Mortality and re-fracture rates in low trauma hip fracture. BMC Geriatr 2024; 24:381. [PMID: 38684943 PMCID: PMC11059755 DOI: 10.1186/s12877-024-04950-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 04/04/2024] [Indexed: 05/02/2024] Open
Abstract
OBJECTIVES This study aimed to estimate the incidence rate of re-fracture and all-cause mortality rate in patients with hip fractures caused by minor trauma in the first year following the event. MATERIALS AND METHODS This is a retrospective cohort study of patients over 50 years of age conducted in a referral hospital located in Tehran (Shafa-Yahyaian). Using the hospital information system (HIS), all patients hospitalized due to hip fractures caused by minor trauma during 2013-2019 were included in the study. We investigated the occurrence of death and re-fracture in all patients one year after the primary hip fracture. RESULTS A total of 945 patients with hip fractures during a 307,595 person-days of follow-up, were included. The mean age of the participants was 71 years (SD = 11.19), and 533 (59%) of them were women. One hundred forty-nine deaths were identified during the first year after hip fracture, resulting in a one-year mortality rate of 17.69% (95% CI: 15.06-20.77). The one-year mortality rate was 20.06% in men and 15.88% in women. Out of all the participants, 667 answered the phone call, of which 29 cases had experienced a re-fracture in the first year (incidence rate = 5.03%, 95% CI: 3.50-7.24). The incidence rates in women and men were 6.07% and 3.65%, respectively. CONCLUSION Patients with low-trauma hip fractures have shown a high rate of mortality in the first year. Considering the increase in the incidence of hip fractures with age, comprehensive strategies are needed to prevent fractures caused by minor trauma in the elderly population.

Optimizing cardiovascular disease mortality prediction: a super learner approach in the tehran lipid and glucose study. BMC Med Inform Decis Mak 2024; 24:97. [PMID: 38627734 PMCID: PMC11020797 DOI: 10.1186/s12911-024-02489-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 03/22/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND & AIM Cardiovascular disease (CVD) is the most important cause of death in the world and has a potential impact on health care costs, this study aimed to evaluate the performance of machine learning survival models and determine the optimum model for predicting CVD-related mortality. METHOD In this study, the research population was all participants in Tehran Lipid and Glucose Study (TLGS) aged over 30 years. We used the Gradient Boosting model (GBM), Support Vector Machine (SVM), Super Learner (SL), and Cox proportional hazard (Cox-PH) models to predict the CVD-related mortality using 26 features. The dataset was randomly divided into training (80%) and testing (20%). To evaluate the performance of the methods, we used the Brier Score (BS), Prediction Error (PE), Concordance Index (C-index), and time-dependent Area Under the Curve (TD-AUC) criteria. Four different clinical models were also performed to improve the performance of the methods. RESULTS Out of 9258 participants with a mean age of (SD; range) 43.74 (15.51; 20-91), 56.60% were female. The CVD death proportion was 2.5% (228 participants). The death proportion was significantly higher in men (67.98% M, 32.02% F). Based on predefined selection criteria, the SL method has the best performance in predicting CVD-related mortality (TD-AUC > 93.50%). Among the machine learning (ML) methods, The SVM has the worst performance (TD-AUC = 90.13%). According to the relative effect, age, fasting blood sugar, systolic blood pressure, smoking, taking aspirin, diastolic blood pressure, Type 2 diabetes mellitus, hip circumference, body mss index (BMI), and triglyceride were identified as the most influential variables in predicting CVD-related mortality. CONCLUSION According to the results of our study, compared to the Cox-PH model, Machine Learning models showed promising and sometimes better performance in predicting CVD-related mortality. This finding is based on the analysis of a large and diverse urban population from Tehran, Iran.

Legacy benefits of blood pressure treatment on cardiovascular events are primarily mediated by improved blood pressure variability: the ASCOT trial. Eur Heart J 2024; 45:1159-1169. [PMID: 38291599 PMCID: PMC10984564 DOI: 10.1093/eurheartj/ehad814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 10/24/2023] [Accepted: 11/29/2023] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND AND AIMS Visit-to-visit systolic blood pressure variability (BPV) is an important predictor of cardiovascular (CV) outcomes. The long-term effect of a period of blood pressure (BP) control, but with differential BPV, is uncertain. Morbidity and mortality follow-up of UK participants in the Anglo-Scandinavian Cardiac Outcomes Trial-Blood Pressure-Lowering Arm has been extended for up to 21 years to determine the CV impact of mean systolic blood pressure (SBP) control and BPV during the trial, and amongst those allocated to amlodipine- and atenolol-based treatment. METHODS Eight thousand five hundred and eighty hypertensive participants (4305 assigned to amlodipine ± perindopril-based and 4275 to atenolol ± diuretic-based treatment during the in-trial period (median 5.5 years) were followed for up to 21 years (median 17.4 years), using linked hospital and mortality records. A subgroup of participants (n = 2156) was followed up 6 years after the trial closure with a self-administered questionnaire and a clinic visit. In-trial mean SBP and standard deviation of visit-to-visit SBP as a measure of BPV, were measured using >100 000 BP measurements. Cox proportional hazard models were used to estimate the risk [hazard ratios (HRs)], associated with (i) mean with SBP and BPV during the in-trial period, for the CV endpoints occurring after the end of the trial and (ii) randomly assigned treatment to events following randomization, for the first occurrence of pre-specified CV outcomes. RESULTS Using BP data from the in-trial period, in the post-trial period, although mean SBP was a predictor of CV outcomes {HR per 10 mmHg, 1.14 [95% confidence interval (CI) 1.10-1.17], P < .001}, systolic BPV independent of mean SBP was a strong predictor of CV events [HR per 5 mmHg 1.22 (95% CI 1.18-1.26), P < .001] and predicted events even in participants with well-controlled BP. During 21-year follow-up, those on amlodipine-based compared with atenolol-based in-trial treatment had significantly reduced risk of stroke [HR 0.82 (95% CI 0.72-0.93), P = .003], total CV events [HR 0.93 (95% CI 0.88-0.98), P = .008], total coronary events [HR 0.92 (95% CI 0.86-0.99), P = .024], and atrial fibrillation [HR 0.91 (95% CI 0.83-0.99), P = .030], with weaker evidence of a difference in CV mortality [HR 0.91 (95% CI 0.82-1.01), P = .073]. There was no significant difference in the incidence of non-fatal myocardial infarction and fatal coronary heart disease, heart failure, and all-cause mortality. CONCLUSIONS Systolic BPV is a strong predictor of CV outcome, even in those with controlled SBP. The long-term benefits of amlodipine-based treatment compared with atenolol-based treatment in reducing CV events appear to be primarily mediated by an effect on systolic BPV during the trial period.

Efficacy and safety of basal insulins in people with type 2 diabetes mellitus: a systematic review and network meta-analysis of randomized clinical trials. Front Endocrinol (Lausanne) 2024; 15:1286827. [PMID: 38586456 PMCID: PMC10997219 DOI: 10.3389/fendo.2024.1286827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 02/22/2024] [Indexed: 04/09/2024] Open
Abstract
Aim The comparative effectiveness of basal insulins has been examined in several studies. However, current treatment algorithms provide a list of options with no clear differentiation between different basal insulins as the optimal choice for initiation. Methods A comprehensive search of MEDLINE, Embase, Cochrane Library, ISI, and Scopus, and a reference list of retrieved studies and reviews were performed up to November 2023. We identified phase III randomized controlled trials (RCTs) comparing the efficacy and safety of basal insulin regimens. The primary outcomes evaluated were HbA1c reduction, weight change, and hypoglycemic events. The revised Cochrane ROB-2 tool was used to assess the methodological quality of the included studies. A random-effects frequentist network meta-analysis was used to estimate the pooled weighted mean difference (WMD) and odds ratio (OR) with 95% confidence intervals considering the critical assumptions in the networks. The certainty of the evidence and confidence in the rankings was assessed using the GRADE minimally contextualized approach. Results Of 20,817 retrieved studies, 44 RCTs (23,699 participants) were eligible for inclusion in our network meta-analysis. We found no significant difference among various basal insulins (including Neutral Protamine Hagedorn (NPH), ILPS, insulin glargine, detemir, and degludec) in reducing HbA1c. Insulin glargine, 300 U/mL (IGlar-300) was significantly associated with less weight gain (mean difference ranged from 2.9 kg to 4.1 kg) compared to other basal insulins, namely thrice-weekly insulin degludec (IDeg-3TW), insulin degludec, 100 U/mL (IDeg-100), insulin degludec, 200 U/mL (IDeg-200), NPH, and insulin detemir (IDet), but with low to very low certainty regarding most comparisons. IDeg-100, IDeg-200, IDet, and IGlar-300 were associated with significantly lower odds of overall, nocturnal, and severe hypoglycemic events than NPH and insulin lispro protamine (ILPS) (moderate to high certainty evidence). NPH was associated with the highest odds of overall and nocturnal hypoglycemia compared to others. Network meta-analysis models were robust, and findings were consistent in sensitivity analyses. Conclusion The efficacy of various basal insulin regimens is comparable. However, they have different safety profiles. IGlar-300 may be the best choice when weight gain is a concern. In contrast, IDeg-100, IDeg-200, IDet, and IGlar-300 may be preferred when hypoglycemia is the primary concern.

The relationship between moral courage and providing safe care in nurses: A cross-sectional study. JOURNAL OF EDUCATION AND HEALTH PROMOTION 2023; 12:352. [PMID: 38144009 PMCID: PMC10743858 DOI: 10.4103/jehp.jehp_977_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 12/01/2022] [Indexed: 12/26/2023]
Abstract
BACKGROUND Moral courage is one of the moral virtues, which can have a great impact on the provision of safe care for patients. Providing safe care is one of the most significant and fundamental principles of healthcare. This study aimed to determine the relationship between moral courage and safe care among nurses and explain the factors predicting safe care. MATERIALS AND METHODS This is a cross-sectional study conducted on 172 nurses who worked in selected hospitals affiliated with the Iran University of Medical Sciences in 2019. For this purpose, self-report questionnaires on moral courage and safe nursing care were used. The collected data were analyzed in the Statistical Package for Social Sciences (SPSS) version 23.0 using descriptive (mean, standard deviation, percentage, and frequency) and inferential (Pearson's correlation coefficient and multiple linear regression) statistics. P values less than 0.05 were considered statistically significant. RESULTS Mean scores of nurses' moral courage and safe care were desirable (407.57 ± 53.97) and satisfactory (311.31 ± 39.48), respectively. There was a significant correlation between the scores of nursing safe care and moral courage (r = 0.69, P < 0.001). Moral courage, gender, and work experience explained 54% of the variance of nursing safe care. CONCLUSION The results showed that there is a positive and significant relationship between safety care and moral courage. It seems that increasing nurses' awareness of ethical principles leads to their courageous ethical behaviors, and safety and high-quality care should be one of the goals of all healthcare professionals. Also, the results of this study support the need to improve the knowledge and awareness of nurses and nurse managers regarding the importance of moral courage in providing safe nursing care and improving patient safety.

Multiple Substance Use Patterns and Its Relationship with Imprisonment in a High-Risk Group of Iranian Adults. J Res Health Sci 2023; 23:e00590. [PMID: 38315905 PMCID: PMC10660508 DOI: 10.34172/jrhs.2023.125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 07/14/2023] [Accepted: 08/15/2023] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND Substance use is recognized as an important factor associated with many diseases and premature deaths and the main risk factor for disability worldwide. This study aims to identify subgroups of substance use in adults and detect the effect of imprisonment on the membership of participants in latent classes of substance use. Study Design: A cross-sectional study. METHODS This study was performed on 930 adult people who were referred to behavioral health counseling centers in Tehran province. All participants completed some checklists and questionnaires. Data analysis was performed using chi-square, Fisher's exact test, and latent class analysis (LCA). RESULTS Four latent classes were identified, including non-users (58%), cigarette smokers (11.6%), users of low stigma substances (27.4%), and drug users (3.1%). After adjusting for other studied variables, having a history of imprisonment increased the odds of membership in the cigarette smoker class (Odds ratio [OR]=5.82, 95%, confidence interval [CI]: 3.19-10.63) and drug user class (OR=53.59, 95% CI: 18.00- 159.52) compared to non-user class. Among all participants, 84 (9.0%) had a history of imprisonment. CONCLUSION Results from the present study indicate that 30.5% of the participants fell under the user of the low-stigma substance or drug user group. Focusing on increasing prisoner's knowledge of the dangers of using different substances and considering various programs for prisoners' leisure time may help reduce substance use prevalence.

Monitoring the COVID-19 Vaccine Acceptance Trend and its Determinants Among Iranian Adults. ARCHIVES OF IRANIAN MEDICINE 2023; 26:427-433. [PMID: 38301104 PMCID: PMC10685739 DOI: 10.34172/aim.2023.65] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 07/06/2023] [Indexed: 02/03/2024]
Abstract
BACKGROUND Vaccination seems to be the most critical means of halting the COVID-19 pandemic. It is crucial to understand the factors that influence COVID-19 vaccine acceptance to avoid low vaccination rates. This study intended to monitor the COVID-19 vaccine acceptance and its association with socio-demographic factors and prior diagnosis of COVID-19 in Iranian adults during the COVID-19 pandemic. METHODS The study utilized data from the COVID-19 Population Survey of Iran (COPSIR), a repeated national survey designed to monitor COVID-19-related behavioral insights. From April 2020 to November 2021, thirteen iterations of a series of cross-sectional studies involving computer-assisted telephone interviews were conducted. RESULTS The COVID-19 vaccine acceptance rate remained above 80% until the ninth wave in February 2021, when it dropped to 62.9%. However, throughout the next four surveys, it rose gradually from 72.0% to 85.7%. The multilevel regression model revealed that the COVID-19 vaccine acceptance was significantly and positively linked with age and education. CONCLUSION Despite the relatively high COVID-19 vaccine acceptance rate among Iranian adults, after the emergence of vaccines on the global market and controversies about their safety in Iran, the initially high vaccine acceptance rate dropped significantly, and then increased over time and returned to its peak level (85%). According to the Commodity Theory, this rise in vaccine acceptance can be attributed to the COVID-19 vaccine shortage in the country between January and July 2022. For Iranian adults to accept vaccines more readily, health promotion programs should target the youth and the less literate adults.

Persistence of immune responses after heterologous and homologous third COVID-19 vaccine dose schedules in the UK: eight-month analyses of the COV-BOOST trial. J Infect 2023; 87:18-26. [PMID: 37085049 PMCID: PMC10116128 DOI: 10.1016/j.jinf.2023.04.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 03/30/2023] [Accepted: 04/18/2023] [Indexed: 04/23/2023]
Abstract
BACKGROUND COV-BOOST is a multicentre, randomised, controlled, phase 2 trial of seven COVID-19 vaccines used as a third booster dose in June 2021. Monovalent messenger RNA (mRNA) COVID-19 vaccines were subsequently widely used for the third and fourth-dose vaccination campaigns in high-income countries. Real-world vaccine effectiveness against symptomatic infections following third doses declined during the Omicron wave. This report compares the immunogenicity and kinetics of responses to third doses of vaccines from day (D) 28 to D242 following third doses in seven study arms. METHODS The trial initially included ten experimental vaccine arms (seven full-dose, three half-dose) delivered at three groups of six sites. Participants in each site group were randomised to three or four experimental vaccines, or MenACWY control. The trial was stratified such that half of participants had previously received two primary doses of ChAdOx1 nCov-19 (Oxford-AstraZeneca; hereafter referred to as ChAd) and half had received two doses of BNT162b2 (Pfizer-BioNtech, hereafter referred to as BNT). The D242 follow-up was done in seven arms (five full-dose, two half-dose). The BNT vaccine was used as the reference as it was the most commonly deployed third-dose vaccine in clinical practice in high-income countries. The primary analysis was conducted using all randomised and baseline seronegative participants who were SARS-CoV-2 naïve during the study and who had not received a further COVID-19 vaccine for any reason since third dose randomisation. RESULTS Among the 817 participants included in this report, the median age was 72 years (IQR: 55-78) with 50.7% being female. The decay rates of anti-spike IgG between vaccines are different among both populations who received initial doses of ChAd/ChAd and BNT/BNT. In the population that previously received ChAd/ChAd, mRNA vaccines had the highest titre at D242 following their vaccine dose although Ad26. COV2. S (Janssen; hereafter referred to as Ad26) showed slower decay. For people who received BNT/BNT as their initial doses, a slower decay was also seen in the Ad26 and ChAd arms. The anti-spike IgG became significantly higher in the Ad26 arm compared to the BNT arm as early as 3 months following vaccination. Similar decay rates were seen between BNT and half-BNT; the geometric mean ratios ranged from 0.76 to 0.94 at different time points. The difference in decay rates between vaccines was similar for wild-type live virus-neutralising antibodies and that seen for anti-spike IgG. For cellular responses, the persistence was similar between study arms. CONCLUSIONS Heterologous third doses with viral vector vaccines following two doses of mRNA achieve more durable humoral responses compared with three doses of mRNA vaccines. Lower doses of mRNA vaccines could be considered for future booster campaigns.

Abstract
Background Hematological inflammatory indices are currently suggested to assess systemic inflammation. This study aims to investigate a vitamin D supplementation effect on hematological indices of inflammation in rats. Method Forty-eight middle-aged male rats were allocated into a normal diet (ND) group (10% fat) and a high-fat diet (HFD) group (60% fat). The animals were fed for 26 weeks. After this period, each group was randomly divided into three subgroups, each of 8 rats: Group (1): animals were fed the ND and HFD containing 1 IU/g vitamin D for 4 months, group (2): animals were fed the ND and HFD containing 6 IU/g vitamin D for 4 months and group (3): animals were euthanized to evaluate the HFD effect. Serum 25-hydroxyvitamin D level, white blood cell count (WBCs), platelet count, platelet crit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) were measured. Results The HFD, significantly increased body weight, PCT, PDW, PLR, NLR, and MLR and significantly reduced serum vitamin D levels compared to the ND (P < 0.05). There was a significant decrease in food intake, MPV, PDW, and NLR after vitamin D supplementation in the ND-fed group (P < 0.05). A significant reduction in platelet count, PCT, and MLR was observed after vitamin D supplementation in HFD-fed rats (P < 0.05). Conclusions In our study, some hemogram-derived inflammatory indices were higher in the HFD-fed group, and vitamin D supplementation lowering effects on some hematological indices were seen in both ND and HFD groups.

Abstract
BACKGROUND Non-communicable diseases behavioral risk factors can be improved if effective interventions are designed considering the health system's capabilities and local resources. This study evaluated the effectiveness of interventions that aimed at increasing non-physician community health workers' motivation in reducing non-communicable diseases behavioral risk factors in the community. METHODS A randomized field trial study was conducted in 32 community health centers in 4 Iranian districts after a baseline population survey on the status of NCDs of 30-70-year-old individuals (n = 1225). The interventions were performed to improve insufficient physical activity, insufficient fruit consumption, insufficient vegetable consumption, high salt intake, and tobacco use. Four intervention packages were implemented in 24 community health centers; the other 8 centers were used as control groups. The non-physician community health workers performed the interventions. The packages additively included goal-setting, evidence-based education, operational planning, and incentive payments. A second survey was conducted 1 year after the start of the interventions to identify the effects on an independent random sample of 30-70-year-old individuals (n = 1221). Difference-in-difference method was used to quantify the interventions' effects. RESULTS The average age of participants in both surveys was about 49 years. Also, about half of the participants were female, and about 43% were illiterate or had a primary school education. The interventions had statistically significant effects only on decreasing the prevalence of insufficient physical activity. The package with all the intervention components decreased the odds of insufficient physical activity to 0.24 (95% CI, 0.08, 0.72). The package with operational planning but no performance-based financing did not change the odds of insufficient physical activity. CONCLUSIONS This study highlighted the importance of components, design, and implementation details of interventions intended to reduce NCDs behavioral risk factors. Some risk factors, such as insufficient physical activity, seem more easily modifiable with limited low-cost interventions in a one-year horizon. However, risk factors related to healthy food consumption and tobacco use need more extensive interventions. TRIAL REGISTRATION This trial was registered on the Iranian Registry of Clinical Trials (IRCT20081205001488N2) on 3 June 2018 ( https://en.irct.ir/trial/774 ).

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders associated with a high risk of diabetes, atherosclerosis, and cardiovascular disease. The purpose of this study was to determine the effect of sumac powder on clinical symptoms and laboratory parameters in women with PCOS. The double-blind randomized controlled clinical trial was conducted on 88 women with PCOS randomly assigned to the intervention and control groups. The intervention group received three capsules each containing 1 g of sumac powder for 12 weeks. All data and serum levels of sex hormone, hs-CRP, glucose, and lipid profiles were measured at the baseline and at the end of the study. Data were analyzed using SPSS version 25 software. The ANCOVA test results showed that hs-CRP level was significantly reduced in the intervention group (p = .008). Blood glucose and lipid profiles in the intervention group were significantly reduced compared to the placebo group (p < .05). Insulin sensitivity and HDL levels were increased significantly in the Sumac group after the intervention (p < .05). Sumac powder can reduce the inflammatory effects, and glycemic status and lipid profile of polycystic ovaries in affected women, but has no significant effect on anthropometric parameters and sex hormones.

[PMID: 36625021 PMCID: PMC10151630 DOI: 10.31616/asj.2022.0011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Accepted: 04/17/2022] [Indexed: 01/11/2023] Open
Abstract
The current study was carried out systematically by conducting a review of the literature. The purpose of this study was to conduct a systematic review of the literature to determine the effects of brace wearing on sagittal parameters in adolescents with idiopathic scoliosis (AIS). In this study, PubMed/MEDLINE (National Library of Medicine), Scopus, Ovid, CINAHL, PEDro, Google Scholar, and the Cochrane Library were accessed and searched using the patient, intervention, comparison, outcome, and study design model. We included studies that looked at the effects of brace treatment on sagittal spinopelvic parameters in AIS patients over the age of 18. The studies were chosen for their cross-sectional, retrospective, or prospective observational designs, and they were published in English. Review articles, case reports, case study designs, and conference abstracts were excluded from consideration. The methodological quality of the remaining articles was assessed using the Newcastle Ottawa Scale. A total of 12 studies were chosen, and 995 participants were evaluated, with 3 (25%) and 9 (75%) having high and moderate quality, respectively. The studies were classified based on the length of follow-up. Long-term, short-term, and immediate effects of brace wearing on sagittal spinopelvic parameters were reported in four, five, and three studies, respectively. The results of nine studies showed a significant decrease in Cobb angle after wearing the brace, which contradicted the findings of the other two. The cervical and sagittal pelvic parameters, thoracic kyphosis (TK), lumbar lordosis (LL), spinopelvic parameters, and sagittal balance were all evaluated in the intended studies, yielding varying results. According to the available literature, wearing a brace flattens the TK and LL. According to this systematic review, brace treatment may affect sagittal spinopelvic parameters in adolescents with AIS, particularly in TK and LL. The cervical and pelvic parameters yielded inconclusive results. This study backs up the idea that brace design and structure can influence sagittal parameter changes. The limitations of this study include different methods of parameter measurement, variations in the brace types and wear time, varying follow-up duration, and differences in participant characteristics.

Evaluation of psychometric properties of the Persian version of the predicaments questionnaire, exploring social attitudes to suicide. Front Public Health 2023; 10:1061673. [PMID: 36703832 PMCID: PMC9872659 DOI: 10.3389/fpubh.2022.1061673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 12/12/2022] [Indexed: 01/07/2023] Open
Abstract
Background Due to the growing prevalence of suicide, assessing people's attitudes toward suicide is necessary. Therefore, this study aimed to examine the psychometric properties of the Persian version of the Predicaments Questionnaire (PQ), measuring social attitudes toward suicide. Methods This psychometrics study evaluated face validity, content validity, temporal stability, internal consistency, and construct validity. First, the questionnaire was translated into Persian by the translate-back-translate method. The Persian version was provided to 10 experts in psychiatry for further revision. Two indicators, CVR and CVI, were calculated to evaluate the content validity. To check the face validity, we prepared a form and gave it to 10 people outside the campus to submit their opinions. Temporal stability was investigated by the test-retest method, reporting Intraclass correlation (ICC). Internal consistency was assessed by reporting Cronbach's alpha and McDonald's Omega coefficients. Construct validity was assessed using the confirmatory factor analysis to determine the number of dimensions of the questionnaire. Results A total of 151 students were enrolled with a mean age of 25 (SD = 0.32). The Persian PQ was valid in terms of content validity and face validity. Furthermore, it was reliable as Cronbach's alpha, McDonald's Omega, and the ICC were 0.94, 0.943, and 0.998, respectively. In addition, the confirmatory factor analysis yielded one dimension. Finally, after reviewing the experts' comments, the final amendments were made, and only question 29 was removed from the final version. Conclusion Consequently, the Persian version of the PQ is acceptable in terms of content validity, face validity, temporal stability, and internal consistency.

Risk-Taking Behaviors Considering Internet Gaming Disorder among Iranian University Students: A Latent Class Analysis. J Res Health Sci 2022; 22:e00556. [PMID: 36511374 PMCID: PMC10422155 DOI: 10.34172/jrhs.2022.91] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 07/28/2022] [Accepted: 08/15/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Dangerous behaviors adversely affect the health of adolescents and young adults. This study aimed to identify the subgroups of college students based on the parameters of risky behavior and analyze the impact of demographic factors and internet gaming disorder (IGD) belonging to each class. STUDY DESIGN A cross-sectional study. METHODS The study was conducted on 1355 students through a multi-stage random sampling method in 2020. A survey questionnaire was used to collect data, and all students completed 1294 sets of questionnaires. The data were analyzed using t test and latent class analysis (LCA) through SPSS and PROC LCA in SAS 9.2 software. RESULTS Three latent classes have been identified as low-risk (75%), tobacco smoker (8%), and high-risk (17%). There was a high possibility of risky behavior in the third class. Marital status (being single) (OR = 2.28, 95% CI: 1.19-4.37), unemployment (having no job) along with education (OR = 1.56, 95% CI: 1.04-2.33), and IGD (OR = 1.06, 95% CI: 1.04-1.09) increased the risk of inclusion in the tobacco smoker class. Moreover, unemployment (having no job) along with education (OR = 1.43, 95% CI: 1.11-1.84) increased the chance of being in the high-risk class. CONCLUSION According to the findings of this study, 25% of the students were tobacco smokers or were in the high-risk class. The results of this study may help develop and evaluate preventive strategies that simultaneously take into account different behaviors.

The impact of probiotic yogurt versus ordinary yogurt on serum sTWEAK, sCD163, ADMA, LCAT and BUN in patients with chronic heart failure: a randomized, triple-blind, controlled trial. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2022; 102:6024-6035. [PMID: 35460085 DOI: 10.1002/jsfa.11955] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 03/20/2022] [Accepted: 04/22/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND To date, no study has investigated the effects of probiotic yogurt as a functional food in patients with chronic heart failure (CHF). Therefore, the aim of this study was to compare the impact of probiotic yogurt versus ordinary yogurt on inflammatory, endothelial, lipid and renal indices in CHF patients. In this randomized, triple-blind clinical trial, 90 patients with CHF were randomly allocated into two groups to take either probiotic or ordinary yogurt for 10 weeks. Serum levels of soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK), soluble cluster of differentiation 163 (sCD163), asymmetric dimethylarginine (ADMA), and lecithin cholesterol acyltransferase (LCAT) were measured by using ELISA kits, and blood urea nitrogen (BUN) was measured by calorimetry method at baseline and at the end of trial. The P-value <0.05 was defined as statistically significant. RESULTS Seventy-eight patients completed the study. At the end of the intervention, the levels of sTWEAK in both groups increased significantly, and this increase was greater in the probiotic yogurt group [691.84 (335.60, 866.95)] compared to control group [581.96 (444.99, 929.40)], and the difference between the groups was statistically significant after adjusting for confounders (P-value: 0.257, adjusted P-value: 0.038). However, no significant differences were found between the groups in the cases of other study indices. CONCLUSION Probiotic yogurt may be useful for improving the inflammatory status in patients with CHF through increasing sTWEAK levels, however, further studies are needed in this area. © 2022 Society of Chemical Industry.

Safety, immunogenicity, and reactogenicity of BNT162b2 and mRNA-1273 COVID-19 vaccines given as fourth-dose boosters following two doses of ChAdOx1 nCoV-19 or BNT162b2 and a third dose of BNT162b2 (COV-BOOST): a multicentre, blinded, phase 2, randomised trial. THE LANCET. INFECTIOUS DISEASES 2022; 22:1131-1141. [PMID: 35550261 PMCID: PMC9084623 DOI: 10.1016/s1473-3099(22)00271-7] [Citation(s) in RCA: 81] [Impact Index Per Article: 40.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 04/19/2022] [Accepted: 04/19/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Some high-income countries have deployed fourth doses of COVID-19 vaccines, but the clinical need, effectiveness, timing, and dose of a fourth dose remain uncertain. We aimed to investigate the safety, reactogenicity, and immunogenicity of fourth-dose boosters against COVID-19. METHODS The COV-BOOST trial is a multicentre, blinded, phase 2, randomised controlled trial of seven COVID-19 vaccines given as third-dose boosters at 18 sites in the UK. This sub-study enrolled participants who had received BNT162b2 (Pfizer-BioNTech) as their third dose in COV-BOOST and randomly assigned them (1:1) to receive a fourth dose of either BNT162b2 (30 μg in 0·30 mL; full dose) or mRNA-1273 (Moderna; 50 μg in 0·25 mL; half dose) via intramuscular injection into the upper arm. The computer-generated randomisation list was created by the study statisticians with random block sizes of two or four. Participants and all study staff not delivering the vaccines were masked to treatment allocation. The coprimary outcomes were safety and reactogenicity, and immunogenicity (anti-spike protein IgG titres by ELISA and cellular immune response by ELISpot). We compared immunogenicity at 28 days after the third dose versus 14 days after the fourth dose and at day 0 versus day 14 relative to the fourth dose. Safety and reactogenicity were assessed in the per-protocol population, which comprised all participants who received a fourth-dose booster regardless of their SARS-CoV-2 serostatus. Immunogenicity was primarily analysed in a modified intention-to-treat population comprising seronegative participants who had received a fourth-dose booster and had available endpoint data. This trial is registered with ISRCTN, 73765130, and is ongoing. FINDINGS Between Jan 11 and Jan 25, 2022, 166 participants were screened, randomly assigned, and received either full-dose BNT162b2 (n=83) or half-dose mRNA-1273 (n=83) as a fourth dose. The median age of these participants was 70·1 years (IQR 51·6-77·5) and 86 (52%) of 166 participants were female and 80 (48%) were male. The median interval between the third and fourth doses was 208·5 days (IQR 203·3-214·8). Pain was the most common local solicited adverse event and fatigue was the most common systemic solicited adverse event after BNT162b2 or mRNA-1273 booster doses. None of three serious adverse events reported after a fourth dose with BNT162b2 were related to the study vaccine. In the BNT162b2 group, geometric mean anti-spike protein IgG concentration at day 28 after the third dose was 23 325 ELISA laboratory units (ELU)/mL (95% CI 20 030-27 162), which increased to 37 460 ELU/mL (31 996-43 857) at day 14 after the fourth dose, representing a significant fold change (geometric mean 1·59, 95% CI 1·41-1·78). There was a significant increase in geometric mean anti-spike protein IgG concentration from 28 days after the third dose (25 317 ELU/mL, 95% CI 20 996-30 528) to 14 days after a fourth dose of mRNA-1273 (54 936 ELU/mL, 46 826-64 452), with a geometric mean fold change of 2·19 (1·90-2·52). The fold changes in anti-spike protein IgG titres from before (day 0) to after (day 14) the fourth dose were 12·19 (95% CI 10·37-14·32) and 15·90 (12·92-19·58) in the BNT162b2 and mRNA-1273 groups, respectively. T-cell responses were also boosted after the fourth dose (eg, the fold changes for the wild-type variant from before to after the fourth dose were 7·32 [95% CI 3·24-16·54] in the BNT162b2 group and 6·22 [3·90-9·92] in the mRNA-1273 group). INTERPRETATION Fourth-dose COVID-19 mRNA booster vaccines are well tolerated and boost cellular and humoral immunity. Peak responses after the fourth dose were similar to, and possibly better than, peak responses after the third dose. FUNDING UK Vaccine Task Force and National Institute for Health Research.

Abstract
Background: A deeper understanding of the dimensions of preparation for aging at the personal level may provide new perspectives for healthy aging promotion policies. Therefore, the present study was conducted to investigate the dimensions of preparation for old age and retirement. Methods: This was a systematic review. The search was performed in the following databases: PubMed, Embase, Scopus, Web of Science, PsycINFO, and Google Scholar up to June 2020. This search was done based on the following keywords: "prepare*", "preparation", "plan* ", "Aged", "Ageing", "Aging", "older people", "senior", "retirement", "older adults", and "elderly" through the AND/OR operators. In the preliminary search, 2032 papers were identified. After removing the duplicated articles and screening the title and abstract, the full text of 141 papers were investigated. Finally, 42 papers were eligible for inclusion in the systematic review. Results: The results indicated that preparation for aging is propounded in the 6 dimensions: (1) health preparation; (2) psychological preparation; (3) financial preparation; (4) housing; (5) social preparation; and (6) active leisure. Conclusion: The findings of the present study indicated that planning for aging requires coverage of all dimensions of old age preparations to achieve healthy aging. The preparation planning should be performed before later life and during the young or middle-age years.

Abstract
Background India is experiencing a rapid health transition with a rising burden of noncommunicable diseases (NCDs), causing significant morbidity and mortality. Cost-effective interventions for comprehensive NCD management can only be designed after assessing the readiness of various health facilities. Objectives This study aimed to assess the preparedness of healthcare facilities of Manipur in the management of NCDs and to assess the knowledge of doctors regarding NCDs. Methods A cross-sectional study was conducted in 21 public healthcare facilities in seven districts of Manipur during October 2021. Readiness of these facilities was assessed through observation and interview of doctors and nurses using a checklist adapted from the WHO Package of Essential NCDs. Knowledge of 153 doctors was also assessed using a self-administered, structured questionnaire. Data were entered in SPSS-26 and expressed using descriptive statistics. Results General readiness index of primary health centers (PHCs), community health centers (CHCs), district hospitals (DHs), and tertiary care centers (TCCs) was 47%, 66.3%, 73.2%, and 70%, respectively. CHCs were ready in the domains of patient care services (80%), human resources (75%), and advocacy (91.7%). DHs and TCCs were ready in terms of patient care services, human resources, record maintenance, referral system, and advocacy. PHCs were not ready in any of the nine domains. Majority of the doctors (88%) had inadequate knowledge regarding NCDs. Conclusion PHCs and CHCs were not adequately prepared, but DHs and TCCs were ready to manage NCDs. More than four-fifth of the doctors had inadequate knowledge. Strengthening PHCs and CHCs and training of healthcare workers are needed for integrated NCD management.

Persistence of immunogenicity after seven COVID-19 vaccines given as third dose boosters following two doses of ChAdOx1 nCov-19 or BNT162b2 in the UK: Three month analyses of the COV-BOOST trial. J Infect 2022; 84:795-813. [PMID: 35405168 PMCID: PMC8993491 DOI: 10.1016/j.jinf.2022.04.018] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 04/04/2022] [Accepted: 04/05/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVES To evaluate the persistence of immunogenicity three months after third dose boosters. METHODS COV-BOOST is a multicentre, randomised, controlled, phase 2 trial of seven COVID-19 vaccines used as a third booster dose. The analysis was conducted using all randomised participants who were SARS-CoV-2 naïve during the study. RESULTS Amongst the 2883 participants randomised, there were 2422 SARS-CoV-2 naïve participants until D84 visit included in the analysis with median age of 70 (IQR: 30-94) years. In the participants who had two initial doses of ChAdOx1 nCov-19 (Oxford-AstraZeneca; hereafter referred to as ChAd), schedules using mRNA vaccines as third dose have the highest anti-spike IgG at D84 (e.g. geometric mean concentration of 8674 ELU/ml (95% CI: 7461-10,085) following ChAd/ChAd/BNT162b2 (Pfizer-BioNtech, hearafter referred to as BNT)). However, in people who had two initial doses of BNT there was no significant difference at D84 in people given ChAd versus BNT (geometric mean ratio (GMR) of 0.95 (95%CI: 0.78, 1.15). Also, people given Ad26.COV2.S (Janssen; hereafter referred to as Ad26) as a third dose had significantly higher anti-spike IgG at D84 than BNT (GMR of 1.20, 95%CI: 1.01,1.43). Responses at D84 between people who received BNT (15 μg) or BNT (30 μg) after ChAd/ChAd or BNT/BNT were similar, with anti-spike IgG GMRs of half-BNT (15 μg) versus BNT (30 μg) ranging between 0.74-0.86. The decay rate of cellular responses were similar between all the vaccine schedules and doses. CONCLUSIONS 84 days after a third dose of COVID-19 vaccine the decay rates of humoral response were different between vaccines. Adenoviral vector vaccine anti-spike IgG concentrations at D84 following BNT/BNT initial doses were similar to or even higher than for a three dose (BNT/BNT/BNT) schedule. Half dose BNT immune responses were similar to full dose responses. While high antibody tires are desirable in situations of high transmission of new variants of concern, the maintenance of immune responses that confer long-lasting protection against severe disease or death is also of critical importance. Policymakers may also consider adenoviral vector, fractional dose of mRNA, or other non-mRNA vaccines as third doses.

Abstract
Background: Health literacy is one of the important social determinants of health. Objective: The aim of this study was to develop an instrument to measure Dietary Supplement Health Literacy (DSHL) of Iranian women. Methods: In this psychometrics study, an initial nine-factor instrument was developed. Face validity and content validity of the instrument were evaluated. The factor structure of the instrument was explored by the Exploratory Factor Analysis (EFA) among 400 women taking Dietary supplement. Confirmatory Factor Analysis (CFA) was done to determine the underlying factor structure of the instrument in this population. The internal and external reliability of the instrument was evaluated. Key Results: According to expert panel opinions, 16 items were deleted. The results of the EFA showed that the Kaiser-Meyer-Olkin and Bartlett's test of sphericity were significant. EFA showed that 30 items could be grouped into nine factors that accounted for 60.84% of the variance. Since two items in the ability to actively engage with health care providers factor were loaded in factor 1, this factor was labeled Engaging in receiving informational supports from health care providers. In addition, one item of the dimension was loaded in factor 3. Given that the one item of factor 5 and 1 item of factor 6 were loaded in a new factor 9, this factor was labeled Applying information to decision-making. The CFA indicated that the nine-factor structure of the DSHL instrument had a poor fit. To modify indices, factor 9 with 2 items and 1 item of factor 6 were deleted. The Cronbach's alpha and intraclass correlation coefficient of the instrument were acceptable. Finally, a 27-item instrument with 8 dimensions was confirmed. Conclusions: The results of the study showed that the instrument developed was a valid tool for identifying the DSHL of Iranian women. [HLRP: Health Literacy Research and Practice. 2022;6(2):e159–e166.] Plain Language Summary: This study sought to develop and validate a multidimensional instrument to measure the health literacy of Iranian women about dietary supplements that was performed from July 2019 to May 2020 in Iran. Findings showed that the 30-item instrument developed in this study is a valid instrument to be used for identifying the health literacy of Iranian women about dietary supplements.

Abstract
Background: The Integrated Health Record System, locally known as the "SIB," is the most used information system for recording public health services provided to the Iranian population. The objective of this study was to evaluate the success rate of the SIB using the Clinical Information System Success Model (CISSM). Methods: This is a psychometric and evaluation study. The CISSM has a 26-item instrument that assesses 7 constructs in 3 following stages: (1) the socio-technical stage (facilitating conditions, social influence, information quality, and system performance(; (2) the integrated stage (system use dependency and user satisfaction); and (3) success outcome stage (net benefit). A Persian version of the CISSM instrument was validated and applied in this study. Based on this instrument, the reliability and the validity of the CISSM were assessed. The SIB success rate was evaluated using a validated CISSM. The study participants were 758 SIB users from different disciplines and different levels.
Results: Assessment of content validity, construct validity, internal consistency, and test-retest reliability showed acceptable psychometric properties of the CISSM instrument. The results demonstrated that the SIB success rate was in the moderate range (59.6%). Facilitating conditions and information quality were strong predictors of use dependency and user satisfaction, while both of these 2 constructs significantly influenced net benefit.
Conclusion: The SIB success was in the moderate range, and it needs to be enhanced. Therefore, Iranian healthcare policymakers should consider working on the most important factors influencing SIB success (facilitating conditions, information quality, use dependency, and user satisfaction) to improve SIB success.

Abstract
Background: The prevalence of metabolic syndrome (MetSyn) is increasing in Iran. This study was an attempt to determine the effects of a short message service (SMS)-based education intervention on knowledge, attitude, and the adoption of preventive behaviors concerning MetSyn among a sample of employees of Iran University of Medical Sciences (IUMS). Methods: In this randomized controlled trial, conducted from January through April 2021, 144 IUMS staff members were assigned either to the intervention group (n=72) or to the control group (n=72). Thirty-two text messages were designed, pretested, and sent to the participants’ phones in the intervention group in 32 days. Knowledge, attitude, and the adoption of preventive behaviors vis-à-vis MetSyn were measured in the intervention group before and 1 month after the intervention and compared with those in the control group at the same time points. The data were analyzed using paired t tests and ANCOVA. Results: The mean age of the employees in the intervention and control groups was 42.97±8.80 and 40.81±9.58 years, respectively. The results showed that the mean scores of knowledge (P<0.001), attitude (P<0.001), and the adoption of preventive behaviors regarding MetSyn (P=0.009) were significantly different between the intervention and control groups after the intervention was done via SMS. Conclusions: The results of the present study showed that SMS-based interventions might improve knowledge, attitude, and the adoption of preventive behaviors pertaining to MetSyn among employees.

Context The World Health Organization proposed the Robson's classification system as a global standard for assessing and comparing cesarean section (CS) rates within health-care facilities over time and between facilities. Aims This study aims to assess the frequency and indications of CS and to identify the groups within the obstetric population contributing to CS using Robson's classification. Settings and Design A retrospective chart review was conducted in a Tertiary Care Teaching Hospital in Imphal, Manipur. Methods All women who delivered between January and December 2019 were classified using the Robson's Ten Group Classification System. The overall CS rate and the CS rate in each Robson's group were calculated. The indications for CS were also recorded. Statistical Analysis Used Descriptive statistics, such as frequency, percentage, mean, and standard deviation, was used. Results A total of 10,282 births were reported. The overall CS rate was 35.2%. Group 3 (multiparous women without previous CS in spontaneous labor) (27.6%) and Group 1 (nulliparous women in spontaneous labor) (23.7%) contributed to most of the obstetric populations. The majority of CS belonged to the women in Group 5 (multiparous women with previous lower segment CS) (11%), followed by Group 2 (nulliparous women with labor induced or prelabor CS) (8.6%) and Group 4 (multiparous women without previous CS were induced or taken for prelabor CS) (5.5%). Conclusions The study revealed that Groups 5, 2, and 4 contributed to the high CS rate. Efforts to reduce the overall CS rate should be directed at increasing vaginal births after CS, performing effective pelvic examinations, and encouraging obstetricians to perform versions when indicated.

IL1RL1 single nucleotide polymorphisms are associated with asthma in the Iranian population. Monaldi Arch Chest Dis 2021; 92. [PMID: 34964571 DOI: 10.4081/monaldi.2021.1697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 12/20/2021] [Indexed: 11/23/2022] Open
Abstract
Asthma is a chronic and multifactorial disease which is known to result from environmental and genetic factors. Interleukin 1 receptor-like 1 (IL1RL1) is a receptor, which promotes inflammatory responses after binding to its ligand IL-33. Several studies have shown that IL1RL1 gene polymorphisms are related to susceptibility or protection to asthma. The objective of this study was to evaluate the association between two IL1RL1 single nucleotide polymorphisms (rs10208293 and rs1041973) and the risk of asthma in the Iranian population. We performed genotyping of the IL1RL1 SNPs in 126 adult asthmatics and 300 healthy controls using TaqMan genotyping assay. Moreover, total serum IgE level, eosinophil count, and skin prick test were accomplished. The results indicated that the AA genotype of rs10208293 was positively associated with asthma susceptibility (p=0.028). We did not find any association between rs1041973 and asthma. Overall, our findings indicate that rs10208293 has a positive association with asthma in the Iranian population.

Safety and immunogenicity of seven COVID-19 vaccines as a third dose (booster) following two doses of ChAdOx1 nCov-19 or BNT162b2 in the UK (COV-BOOST): a blinded, multicentre, randomised, controlled, phase 2 trial. Lancet 2021; 398:2258-2276. [PMID: 34863358 PMCID: PMC8639161 DOI: 10.1016/s0140-6736(21)02717-3] [Citation(s) in RCA: 407] [Impact Index Per Article: 135.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 11/17/2021] [Accepted: 11/19/2021] [Indexed: 01/12/2023]
Abstract
BACKGROUND Few data exist on the comparative safety and immunogenicity of different COVID-19 vaccines given as a third (booster) dose. To generate data to optimise selection of booster vaccines, we investigated the reactogenicity and immunogenicity of seven different COVID-19 vaccines as a third dose after two doses of ChAdOx1 nCov-19 (Oxford-AstraZeneca; hereafter referred to as ChAd) or BNT162b2 (Pfizer-BioNtech, hearafter referred to as BNT). METHODS COV-BOOST is a multicentre, randomised, controlled, phase 2 trial of third dose booster vaccination against COVID-19. Participants were aged older than 30 years, and were at least 70 days post two doses of ChAd or at least 84 days post two doses of BNT primary COVID-19 immunisation course, with no history of laboratory-confirmed SARS-CoV-2 infection. 18 sites were split into three groups (A, B, and C). Within each site group (A, B, or C), participants were randomly assigned to an experimental vaccine or control. Group A received NVX-CoV2373 (Novavax; hereafter referred to as NVX), a half dose of NVX, ChAd, or quadrivalent meningococcal conjugate vaccine (MenACWY)control (1:1:1:1). Group B received BNT, VLA2001 (Valneva; hereafter referred to as VLA), a half dose of VLA, Ad26.COV2.S (Janssen; hereafter referred to as Ad26) or MenACWY (1:1:1:1:1). Group C received mRNA1273 (Moderna; hereafter referred to as m1273), CVnCov (CureVac; hereafter referred to as CVn), a half dose of BNT, or MenACWY (1:1:1:1). Participants and all investigatory staff were blinded to treatment allocation. Coprimary outcomes were safety and reactogenicity and immunogenicity of anti-spike IgG measured by ELISA. The primary analysis for immunogenicity was on a modified intention-to-treat basis; safety and reactogenicity were assessed in the intention-to-treat population. Secondary outcomes included assessment of viral neutralisation and cellular responses. This trial is registered with ISRCTN, number 73765130. FINDINGS Between June 1 and June 30, 2021, 3498 people were screened. 2878 participants met eligibility criteria and received COVID-19 vaccine or control. The median ages of ChAd/ChAd-primed participants were 53 years (IQR 44-61) in the younger age group and 76 years (73-78) in the older age group. In the BNT/BNT-primed participants, the median ages were 51 years (41-59) in the younger age group and 78 years (75-82) in the older age group. In the ChAd/ChAD-primed group, 676 (46·7%) participants were female and 1380 (95·4%) were White, and in the BNT/BNT-primed group 770 (53·6%) participants were female and 1321 (91·9%) were White. Three vaccines showed overall increased reactogenicity: m1273 after ChAd/ChAd or BNT/BNT; and ChAd and Ad26 after BNT/BNT. For ChAd/ChAd-primed individuals, spike IgG geometric mean ratios (GMRs) between study vaccines and controls ranged from 1·8 (99% CI 1·5-2·3) in the half VLA group to 32·3 (24·8-42·0) in the m1273 group. GMRs for wild-type cellular responses compared with controls ranged from 1·1 (95% CI 0·7-1·6) for ChAd to 3·6 (2·4-5·5) for m1273. For BNT/BNT-primed individuals, spike IgG GMRs ranged from 1·3 (99% CI 1·0-1·5) in the half VLA group to 11·5 (9·4-14·1) in the m1273 group. GMRs for wild-type cellular responses compared with controls ranged from 1·0 (95% CI 0·7-1·6) for half VLA to 4·7 (3·1-7·1) for m1273. The results were similar between those aged 30-69 years and those aged 70 years and older. Fatigue and pain were the most common solicited local and systemic adverse events, experienced more in people aged 30-69 years than those aged 70 years or older. Serious adverse events were uncommon, similar in active vaccine and control groups. In total, there were 24 serious adverse events: five in the control group (two in control group A, three in control group B, and zero in control group C), two in Ad26, five in VLA, one in VLA-half, one in BNT, two in BNT-half, two in ChAd, one in CVn, two in NVX, two in NVX-half, and one in m1273. INTERPRETATION All study vaccines boosted antibody and neutralising responses after ChAd/ChAd initial course and all except one after BNT/BNT, with no safety concerns. Substantial differences in humoral and cellular responses, and vaccine availability will influence policy choices for booster vaccination.

Investigation on factors associated with ovarian cancer: an umbrella review of systematic review and meta-analyses. J Ovarian Res 2021; 14:153. [PMID: 34758846 PMCID: PMC8582179 DOI: 10.1186/s13048-021-00911-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Accepted: 10/26/2021] [Indexed: 12/25/2022] Open
Abstract
Following cervical and uterine cancer, ovarian cancer (OC) has the third rank in gynecologic cancers. It often remains non-diagnosed until it spreads throughout the pelvis and abdomen. Identification of the most effective risk factors can help take prevention measures concerning OC. Therefore, the presented review aims to summarize the available studies on OC risk factors. A comprehensive systematic literature search was performed to identify all published systematic reviews and meta-analysis on associated factors with ovarian cancer. Web of Science, Cochrane Library databases, and Google Scholar were searched up to 17th January 2020. This study was performed according to Smith et al. methodology for conducting a systematic review of systematic reviews. Twenty-eight thousand sixty-two papers were initially retrieved from the electronic databases, among which 20,104 studies were screened. Two hundred seventy-seven articles met our inclusion criteria, 226 of which included in the meta-analysis. Most commonly reported genetic factors were MTHFR C677T (OR=1.077; 95 % CI (1.032, 1.124); P-value<0.001), BSML rs1544410 (OR=1.078; 95 %CI (1.024, 1.153); P-value=0.004), and Fokl rs2228570 (OR=1.123; 95 % CI (1.089, 1.157); P-value<0.001), which were significantly associated with increasing risk of ovarian cancer. Among the other factors, coffee intake (OR=1.106; 95 % CI (1.009, 1.211); P-value=0.030), hormone therapy (RR=1.057; 95 % CI (1.030, 1.400); P-value<0.001), hysterectomy (OR=0.863; 95 % CI (0.745, 0.999); P-value=0.049), and breast feeding (OR=0.719, 95 % CI (0.679, 0.762) and P-value<0.001) were mostly reported in studies. Among nutritional factors, coffee, egg, and fat intake significantly increase the risk of ovarian cancer. Estrogen, estrogen-progesterone, and overall hormone therapies also are related to the higher incidence of ovarian cancer. Some diseases, such as diabetes, endometriosis, and polycystic ovarian syndrome, as well as several genetic polymorphisms, cause a significant increase in ovarian cancer occurrence. Moreover, other factors, for instance, obesity, overweight, smoking, and perineal talc use, significantly increase the risk of ovarian cancer.

Randomized Study of the Effects of Zinc, Vitamin A, and Magnesium Co-supplementation on Thyroid Function, Oxidative Stress, and hs-CRP in Patients with Hypothyroidism. Biol Trace Elem Res 2021; 199:4074-4083. [PMID: 33409923 DOI: 10.1007/s12011-020-02548-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 12/16/2020] [Indexed: 10/22/2022]
Abstract
Hypothyroidism can occur due to deficiencies in micronutrients such as zinc, magnesium, and vitamin A. The aim of this study was to determine the effects of supplementation with these micronutrients on thyroid function, oxidative stress, and hs-CRP levels in patients with hypothyroidism. In a randomized double-blind, placebo-controlled trial with two parallel groups, 86 hypothyroid patients aged 20-65 were allocated to receive daily supplementation with either: (intervention group, n = 43) one 30 mg zinc gluconate capsule per day, one 250 mg magnesium oxide tablet per day, and one 25,000 IU vitamin A capsule twice/week for 10 weeks or (placebo group, n = 43) placebo capsules and tablets as above for 10 weeks. Neither of the groups changed their diet or physical activity. Thyroid hormones (free and total thyroxine (FT4 and TT4), free tri-iodothyronine (FT3), and thyroid-stimulating hormone (TSH)), oxidative markers (malondialdehyde (MDA) and total antioxidant capacity (TAC)), serum hs-CRP, and anthropometric indices (height and weight) were assessed at the baseline and at the end of the study. In the intervention group, we found a significant increase in serum FT4, decreased anthropometric indices, and lower levels of serum hs-CRP by the end of the 10 week protocol (P < 0.05). In the placebo group, serum TAC was decreased and hs-CRP increased (P < 0.05), with no significant changes in serum TSH, FT3, TT4, and MDA after the intervention. Zinc, vitamin A, and magnesium supplementation may have beneficial effects in patients with hypothyroidism and in diseases associated with hyperthyroidism.

Abstract
Background: The need for informed policymaking highlights the importance of data on human immunodeficiency virus (HIV) prevalence on key populations. In this systematic review and meta-analysis, we aimed to provide an overview of HIV prevalence in men who have sex with men (MSM) in Iran. Methods: We searched literature published between January 2008 and December 2019 to identify studies reporting the prevalence of HIV infection or acquired immunodeficiency syndrome (AIDS) in a population of adult Iranian men with history of sexual contact with other men. We employed Metaprop command in Stata to pool proportions from different studies. Results: Among the 16 studies retrieved, 2 were performed on MSM population directly, 7 among people who inject drugs, 4 among prisoners, 2 among the homeless, and 1 among methamphetamine users. HIV prevalence was 7% (95% CI, 5%-10%) based on the meta-analysis, although noticeable heterogeneity existed because of target population, study year, and study location, which imposed limitations to provide a robust summary measure for the prevalence of HIV. Conclusion: There is a potential risk of observing a high prevalence of HIV in MSM that could hamper the results of various preventive strategies and their achievements in other subpopulations.

Abstract
Background:
Ischemic cardiomyopathies are the leading causes of mortality and morbidity. Stem cell therapy using amniotic membrane mesenchymal stem cells have emerged as a promising cardiac regeneration modality. They have shown great immunological advantage when used in allogeneic or xenogeneic transplantation. The aim of the current study is to accumulate evidence from published preclinical studies on the application of amniotic membrane derived mesenchymal stem cells (AMSCs) in the treatment of ischemic cardiomyopathies including myocardial ischemia and heart failure. The aim is to define if there is enough high-quality current evidence to support starting the use of these cells in clinical trials.
Methods:
PubMed, SCOPUS, EMBASE, and ISI Web of Science databases were searched without temporal and language restrictions. Data were extracted from selected studies. The primary outcomes were left ventricular ejection fraction (LVEF) and LV fibrosis. The risk of bias (ROB) assessment was performed using SYRCLE's ROB tool. After qualitative synthesis, provided that data meets the criteria for quantitative analysis, a meta-analysis was performed using Stata software V12 to investigate the heterogeneity of the data and to get an overall estimate of the effect size of the treatment on each outcome.
Results:
On primary search, 438 citations were retrieved. After screening, three studies were selected for quantitative analysis of each of the outcomes LVEF and LV fibrosis. Their administration in acute and chronic MI alleviates heart failure and improves LVEF (SMD=3.56, 95% CI: 2.24-4.87, I-squared=83.1%, p=0.003) and reduces infarct size (SMD= -4.41, 95% CI: (-5.68)-(-3.14), I-squared=79.0%, p=0.009). These observations were achieved in the acute MI model, HF following ischemia due to coronary artery stenosis and coronary artery occlusion with the early restoration of the perfusion. Conclusion:
Present low and medium quality evidence from preclinical studies confirm the efficacy of the AMSCs in the preclinical models of acute MI and HF following ischemia due to coronary artery stenosis and permanent/temporary coronary artery occlusion. High-quality preclinical studies are indicated to bridge the gaps in translation of the current findings of AMSCs research for the treatment of patients with acute and chronic myocardial ischemia and heart failure.

Abstract
Background Identifying strategies to optimize participation in health studies is one of the major concerns for researchers. The purpose of this study was to evaluate the efficiency of different invitation strategies on participation rate in the Employees’ Health Cohort Study of Iran (EHCSIR). Methods Two cluster-randomized trials were carried out to assess the outcomes of different invitation strategies. In the first phase, 7 units with 1880 employees (3 hospitals, 3 health centers, and 1 office) were assigned to the three parallel modes of invitation: 1) invitation letter, 2) phone call and 3) Short Message Service (SMS). In the second phase, 6 hospitals with 1633 employees were allocated to two invitation methods: 1) invitation letter, 2) invitation letter plus EHCSIR project introduction video. All groups were followed up by phone calls. A logistic mixed-effects model was used to compare the effectiveness of the strategies. The cost-effectiveness of the interventions was also compared. Results In the first phase, the participation rates in the invitation letter, phone call, and SMS groups were 27.04% (182/673), 21.55% (131/608), and 22.54% (135/599), respectively. Using an invitation letter was significantly more successful than SMS (Adjusted Odds Ratio = 1.80, 95% CI =1.14 to 2.85). Average Cost-Effectiveness Ratios (ACER) were $1.37, $1.42, and $1.55 for the invitation letter, phone call, and SMS, respectively. In the second phase, adding a project introduction video to the invitation letter did not significantly influence the participation rate (Adjusted OR = 0.58, 95% CI =0.24 to 1.36). The ACER was $1.21 for the invitation letter only and $2.01 for the invitation letter plus the introduction video. Conclusions In comparison with the phone call and SMS, the invitation letter is the most effective invitation method for public sector employees to participate in a cohort study. Sending an introduction video did not significantly increase the participation rate compared to sending an invitation letter only.

Abstract
Background & Aim: Self-care in patients with heart failure can improve multiple outcomes and reduce mortality. Measuring self-care requires valid and reliable tools. This study aimed to determine the psychometric properties of the 9-items European Heart Failure Self-Care Behavior Scale.
Methods & Materials: The present study is a psychometric evaluation. The original version of the tool was translated from English to Persian using the standard Backward-Forward method. The questionnaire's validity was assessed using face, content, criterion (the Self-Care of Heart Failure Index v.6 as a criterion), and construct validity. An exploratory factor analysis approach was used to construct validity with a sample of 216 patients with chronic heart failure referred to Dr. Shariati and Imam Khomeini Hospital's heart clinics in Tehran; and Ayatollah Mousavi Hospital in Zanjan. The reliability of the questionnaire was evaluated by internal consistency and stability methods.
Results: After the validation process (validity and reliability), all 9 items of the questionnaire were approved and remained. The content validity index of the total content of the questionnaire was calculated to be 0.96. Based on factor analysis, only one factor was confirmed for the questionnaire. The correlation between the present questionnaire and the Self-Care of Heart Failure Index v.6 was positive and significant (p<0.001, r=0.753). Internal consistency (α=0.728) and stability (0.897) of the questionnaire were also confirmed.
Conclusion: The European Heart Failure Self-Care Behavior Scale is valid and reliable for measuring Iranian patients' self-care behaviors with heart failure.

Abstract
BACKGROUND Self-reported substance use is more likely to be influenced by underreporting bias compared to the biological markers. Underreporting bias or validity of self-reported substance use depends on the study population and cannot be generalized to the entire population. This study aimed to compare the validity of self-reported substance use between research setting and primary health care setting from the same source population. METHODS AND MATERIALS The population in this study included from Rafsanjan Youth Cohort Study (RYCS) and from primary care health centers. The sample from RYCS is made up 607 participants, 113 (18.62%) women and 494 (81.38%) men and sample from PHC centers is made up 522 individuals including 252 (48.28%) women and 270 (51.72%) men. We compared two groups in respect of prevalence estimates based on self-reported substance use and urine test. Then for evaluating validity of self-reported substance use in both group, the results of reference standard, urine tests, were compared with the results of self-reported drug use using measures of concordance. RESULTS The prevalence of substance use based on urine test was significantly higher in both settings compared to self-reported substance use over the past 72 h. The sensitivity of self-report substance use over the past 72 h in research setting was 39.4, 20, 10% and zero for opium, methadone, cannabis and amphetamine, respectively and in primary health care setting was 50, 20.7, 12.5% and zero for opium, methadone, cannabis and amphetamine, respectively. The level of agreement between self-reported substance use over the past 72 h and urine test indicated fair and moderate agreement for opium in both research and primary health care settings, respectively and also slight agreement for methadone and cannabis in both settings were reported. There was no significant difference between the two groups in terms of self-reported substance use. For all substances, the level of agreement increased with longer recall periods. The specificity of self-report for all substances in both groups was more than 99%. CONCLUSION Individuals in primary health care setting were more likely to self-reported substance use than in research setting, but setting did not have a statistically significant effect in terms of self-reported substance use. Programs that rely on self-reported substance use may not estimate the exact prevalence of substance use in both research and primary health care settings, especially for substances that have a higher social stigma. Therefore, it is recommended that self-report and biological indicators be used for more accurate evaluation in substance use studies. It is also suggested that future epidemiological studies be performed to reduce bias of social desirability and find a method providing the highest level of privacy.

Abstract
BACKGROUND Diabetes is a chronic disease and the prevalence of it is rapidly increasing. Recently, the use of natural products in chronic diseases such as diabetes has gained more attention. Chlorella, a single-celled green alga, is one of them. There have been some studies on the effects of chlorella supplementation in chronic diseases such as NAFLD, prediabetes, and diabetic mice, but none of them examined the effects of chlorella in patients with T2DM. The present study was designed to evaluate the effects of chlorella supplementation on glycemic control, lipid profile, and anthropometric indices in type 2 diabetic patients. METHODS This study is a double-blind, randomized controlled trial. 84 patients with T2DM assigned into two groups, receiving 1500 mg/day C. vulgaris or placebo for 8 weeks. Anthropometric information, blood pressure, 24-h food intake recall, and blood samples were collected at the beginning and end of the study to determine the changes of FBS, HbA1c, insulin concentration, insulin resistance, and lipid profile. RESULTS None of the variables investigated in this study showed a significant change after 8 weeks of intervention with C. vulgaris. CONCLUSION According to the findings of this study, supplementation with C. vulgaris with a dosage of 1500 mg/day for 8 weeks, does not improve the anthropometric measurements, glycemic status, and lipid profile as well. Thus, it cannot be considered as a complementary therapeutic approach to common medications at this dosage and duration. However, future studies with a higher dosage of C. vulgaris and more prolonged than 8 weeks are needed to be done.

Abstract
BACKGROUND Sitagliptin is known as an antidiabetic agent inhibiting the dipeptidyl peptidase-4. Although sitagliptin may influence weight, controversial results have been reported, and there is no general agreement on this issue. Therefore, this study assessed the effect of sitagliptin as monotherapy and add-on therapy to metformin on weight reduction in overweight or obese cases with type 2 diabetes. METHODS We reviewed the following databases to identify all relevant papers published until 1st April 2021: Web of Science, MEDLINE, Embase, Scopus, Cochrane Central Register of Controlled Trials Cochrane Library, and Google Scholar. The research included all clinical trials investigating the effect of sitagliptin in obese or overweight adult patients with type 2 diabetes without any language restriction. RESULTS In total, eighteen randomized controlled trials with 2009 participants were included in our meta-analysis. Results showed supplementation of sitagliptin has led to weight loss for sitagliptin treated (MD -0.99; 95% CI; (-1.87, -0.12); p=0.026)) and sitagliptin+metformin treated groups (MD -1.09; 95% CI; (-1.69, -0.49); p<0.001)). Also, the intervention has influenced body mass index in sitagliptin treated (MD -0.23; 95% CI; (-0.45, 0.02); p=0.033)) and sitagliptin+metformin treated groups (MD -0.52; 95% CI; (-0.96, 0.08); p=0.020)) comparing to placebo. CONCLUSION Our results demonstrated that sitagliptin administration with or without metformin might reduce the body weight and body mass index if these drugs are taken for more than 6 months.

Psychometric evaluation of the perceived access to health care questionnaire. BMC Health Serv Res 2021; 21:638. [PMID: 34215250 PMCID: PMC8254360 DOI: 10.1186/s12913-021-06655-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 06/17/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND AND OBJECTIVE Access to health care is a universal concern. Therefore, this study was conducted to develop a questionnaire to assess the Perceived Access to Health care based on Penchansky and Thomas's definition of access and the assessment of its psychometric properties. METHOD The initial questionnaire contains 31 items developed based on a deductive approach with an extensive review of the related literature. Content validity, face validity, construct validity, internal consistency, and instrument reliability were further examined. Data analysis was conducted using SPSS software version 24, R software version 4, and lavaan package. RESULTS The initial questionnaire was examined using qualitative content validity, and the necessary modifications were applied to each item. The content validity ratio (CVR) was approved in 30 items with a value greater than 0.78, and one item with a CVR value lower than 0.78 was removed. In the case of the content validity index (CVI), 29 items were approved with a CVI value of greater than 0.79, and one item with a CVI value between 0.70 and 0.79 was revised. In qualitative face validity, all items were approved by a panel of experts and the participants. All 30 items with an impact score index higher than 1.5 were approved for the next steps. The confirmatory factor analysis results showed that the six-factor model of access to health care has an appropriate fit. Cronbach's alpha coefficient for the questionnaire was calculated 0.86. The value of Cronbach's alpha for the dimensions of availability, accessibility, affordability, accommodation, acceptability, and awareness were 0.61, 0.76, 0.66, 0.60, 0.80, and 0.76, respectively. The Intraclass Correlation Index (ICC) value for reliability (test-retest) of the whole instrument was calculated 0.94 using the two-way mixed absolute agreement method. CONCLUSION The success of health programs depends on eliminating barriers to access to provided health care services. One of the most critical barriers to understanding access is a perception of limited access. This questionnaire might be used further to understand perceived health care access in different global contexts.

Assessing research misconduct in Iran: a perspective from Iranian medical faculty members. BMC Med Ethics 2021; 22:74. [PMID: 34154574 PMCID: PMC8215315 DOI: 10.1186/s12910-021-00642-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 06/10/2021] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Research misconduct is a global concern in biomedical science. There are no comprehensive data regarding the perception and situation of scientific misconduct among the Iranian medical faculty members. We conducted a nationwide survey to assess the research misconduct among the medical faculty members in Iran. METHODS We used the Persian version of the research misconduct questionnaire (PRMQ) on the Google Forms platform. We sent the survey link to a systematic random sample of medical faculty members in Iran (N = 4986). Descriptive analyses were performed on the individual items of the PRMQ, with frequencies and percentages for categorical and Likert-type response items, and means and standard deviation (S.D.) for continuous variables. Chi-square analysis was conducted to test hypotheses examining differences in the frequency of responses related to factors influencing misconduct. We also defined four tenure categories (TC) based on the working years of the participants as tenured faculty members. All the analyses were performed using R 3.6.0. RESULTS The response rate was 13.8% (692 responses). Nearly 70% of the respondents agreed that their publication output would be of higher quality if there were no publication pressure. Approximately three-quarters (N =499, 72.1%) of the respondents had been aware of some instances of research misconduct during the previous year according to their understanding of misconduct. Among the participants, 18.5% perceived the effectiveness of their associated organisation's rules for reducing research misconduct to be high or very high. Pressure for tenure was identified as the item most frequently perceived with a strong behavioural influence on engaging in research misconduct (80.2%). CONCLUSIONS This study confirms that research misconduct needs to be actively addressed among the medical faculty members. Making policies with a focus on boosting awareness regarding the occasions of scientific misconduct and its management seems to be indispensable in the future in Iran.

Abstract
BACKGROUND Heparin is an anticoagulant medication that is usually injected subcutaneously. Subcutaneous administration of heparin may result in complications such as bruising, haematoma, and pain at the injection site. One of the factors that may affect pain, haematoma, and bruising is injection speed. Several studies have been carried out to determine if speed of injection affects the amount of pain and bruising where the injection is given; however, the results of these studies have differed, and study authors have not reached a clear final conclusion. This is the second update of a review first published in 2014. OBJECTIVES To assess the effects of duration (speed) of subcutaneous heparin injection on pain and bruising at the injection site in people admitted to hospitals or clinics who require treatment with unfractionated heparin (UFH) or low molecular weight heparin (LMWH). We also looked at haematoma at the injection site. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 22 June 2020. We undertook reference checking of included studies to identify additional studies. SELECTION CRITERIA We searched for randomised controlled trials (RCTs) comparing the effects of different durations of subcutaneous injection of heparin on pain, bruising, and haematoma at the injection site. DATA COLLECTION AND ANALYSIS For this update, two review authors independently selected studies and extracted data via Covidence software and assessed methodological quality using Cochrane's risk of bias tool. The primary outcomes of interest were pain intensity at injection site and size and incidence of bruising. The secondary outcomes of interest were size and incidence of haematoma at injection site. We calculated the odds ratio (OR), mean difference (MD), or standardised mean difference (SMD) with corresponding 95% confidence intervals (CIs). We assessed the certainty of the evidence using GRADE criteria. MAIN RESULTS We identified one new study for this update, resulting in a total of five included studies with 503 participants who received subcutaneous injections of LMWH into the abdomen. Given the nature of the intervention, it was not possible to blind participants and caregivers (personnel) in any of the included studies. Two studies described blinding of outcome assessors. Overall, the methodological quality of included studies was moderate. The duration of the fast injection was 10 seconds, and the duration of the slow injection was 30 seconds in all included studies. Four studies reported site pain intensity after each injection at different time points. Two studies assessed site pain intensity immediately after each injection; meta-analysis showed no evidence of a difference in site pain intensity immediately after slow injection when compared to fast injection (MD -1.52, 95% CI -3.56 to 0.53; 140 participants; low-certainty evidence). Meta-analysis of three studies indicated that site pain intensity may be slightly reduced 48 hours after the slow heparin injection compared to fast injection (MD -1.60, 95% CI -2.69 to -0.51; 103 participants; low-certainty evidence). Five studies assessed bruise size at 48 hours, and two studies assessed bruise size at 60 hours. Meta-analysis showed there may be a reduction in bruise size 48 hours (SMD -0.54, 95% CI -1.05 to -0.02; 503 participants; 5 studies; very low-certainty evidence) and 60 hours (SMD -0.49, 95% CI -0.93 to -0.06; 84 participants; 2 studies; low-certainty evidence) after slow injection compared to fast injection. There was no evidence of a difference in bruise size 72 hours after slow injection compared to fast injection (SMD -0.27, 95% CI -0.61 to 0.06; 140 participants; 2 studies; low-certainty evidence). Three studies evaluated incidence of bruising and showed there may be a reduction in bruise incidence 48 hours (OR 0.39, 95% CI 0.26 to 0.60; 444 participants; low-certainty evidence) and 60 hours (OR 0.25, 95% CI 0.10 to 0.65; 84 participants; 2 studies; low-certainty evidence) after slow injection compared to fast injection. We downgraded the certainty of the evidence due to risk of bias concerns, imprecision, and inconsistency. None of the included studies measured size or incidence of haematoma. AUTHORS' CONCLUSIONS Administering medication safely and enhancing patient comfort are the main aims of clinical nurses. In this review, we identified five RCTs that evaluated the effect of subcutaneous heparin injection duration on pain intensity, bruise size and incidence. We found that pain may be slightly reduced 48 hours after slow injection. Similarly, there may be a reduction in bruise size and incidence after slow injection compared to fast injection 48 and 60 hours postinjection. We downgraded the certainty of the evidence for all outcomes to low or very low due to risk of bias concerns, imprecision, and inconsistency. Accordingly, new trials with a more robust design, more participants, and a focus on different injection speeds will be useful in strengthening the certainty of the available evidence.

[PMID: 34085881 DOI: 10.1080/01635581.2021.1933096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/24/2022]
Abstract
BACKGROUND AND AIM Breast cancer-related lymphedema (BCRL) is a treatment-related inflammatory complication in breast cancer survivors (BCSs). This study was aimed to evaluate the effect of synbiotic supplementation on serum concentrations of IL-10, TGF-β, VEGF, adiponectin, and edema volume among overweight or obese BCSs with lymphedema following a low-calorie diet (LCD). METHOD In a randomized double-blind, controlled clinical trial, 88 obese and overweight BCSs women were randomized to synbiotic supplement (n = 44) or placebo (n = 44) groups and both groups followed an LCD for 10 weeks. Pre- and post-intervention comparisons were made regarding the anti-inflammatory markers which included IL-10, TGF-β, VEGF, adiponectin, edema volume, and anthropometric measurements. Also, the same factors were analyzed to find inter-group disparities. RESULTS There were no significant differences among participants in the baseline, except for IL-10 and adiponectin. Post-intervention, no significant differences were observed regarding the anti-inflammatory markers, including IL-10, VEGF, adiponectin, and TGF-β between the groups. After 10 weeks of intervention edema volume significantly decreased in the synbiotic group; additionally, anthropometric measurements (body weight, BMI, body fat percent, and WC) decreased in both groups significantly (P < 0.001 and P < 0.005; respectively). CONCLUSION Synbiotic supplementation coupled with an LCD in a 10-week intervention had beneficial effects on increasing the serum TGF-β, IL-10, and adiponectin levels in women with BCRL. It also reduced arm lymphedema volume. Therefore, synbiotic supplementation can be effective in improving health status in BCRL patients.

Abstract
Purpose: To compare the video observation of procedural skills (VOPS) method with the direct observation of procedural skills (DOPS) method in the assessment of senior residents' performance utilizing the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric for phacoemulsification (ICO-OSCAR; phaco). Methods: This is a prospective comparative study conducted at a university-affiliated hospital. Six ophthalmology residents of postgraduate year 4 participated. Their performance in phacoemulsification was rated via DOPS and later in a masked manner through VOPS by a single faculty assessor. Results: Seventy-one surgeries were evaluated. There were no statistically significant differences between the scores of VOPS and DOPS regarding all ICO-OSCAR indices except “instrument insertion into the eye” in which DOPS had higher scores (P = 0.035). A significant correlation was observed in total scores of “task-specific” (r = 0.64, P < 0.001) and “global” (r = 0.38, P = 0.003) indices between VOPS and DOPS while some subscales did not show a correlation between the two methods of assessment. The Bland-Altman analysis demonstrated that nearly all data points of total “task-specific” and “global” scores fell within the 95% limits of agreement ([-5.84, 6.87] and [-4.78, 4.86], respectively). Conclusion: This study demonstrated that VOPS holds promise for a general rating of residents' performance.

[PMID: 34277503 PMCID: PMC8278023 DOI: 10.47176/mjiri.35.66] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Indexed: 11/09/2022] Open
Abstract
Background: Risk factors of noncommunicable diseases (NCD) are increasingly contributing to morbidity and mortality in Iran. Health care providers’ competencies and motivation are essential factors for the success and efficiency of primary health care. This field trial aims to evaluate the impact of a results-based motivating system on population level of the NCD risk factors field trial (IRPONT) in Iran.
Methods: Population groups of 24 rural or urban catchment areas from 3 provinces were randomized to 1 of the 4 types of study groups. The groups were defined based on a set of 4 intervention packages. Extra 8 rural or urban catchment areas in a separate city were considered as independent nonintervention (control) group. Population levels of major NCD risk factors in all 32 population groups were measured at the beginning of the trial, at the end of the first year, and will be measured in the second year through standardized population surveys. As the outcome measure, the difference in population levels of the risk factors will be compared among the study groups. Study group IV will be compared with combined control groups (study groups I, II, and III). Also, we will conduct subgroup analysis to determine the effects of interventions 2, 3, and 4. Ethics: This trial has received ethical approval from National Institute for Medical Research Development in Iran (IR.NIMAD.REC.1396.084) in 2017. Trial Registration Number: This trial has been registered on the Iranian Registry of Clinical Trials (identifier: IRCT20081205001488N2). Registered on 3 June 2018 and updated on 12 April 2020.

Abstract
Background Congenital hypothyroidism (CH) is the most important cause of mental and physical retardation in newborns. The prevalence of CH has been reported high in East Azerbaijan province of Iran. However, the risk factors for CH are poorly understood. This study aimed to determine and compare risk factors for permanent and transient CH in East Azerbaijan, Iran. Methods A case-control study was conducted in the Iranian national screening program for CH. This study included 680 neonates: 340 neonates with confirmed CH and 340 matched healthy controls born at the same period and from the same residential area as the cases. Multiple logistic regression analyses were used to estimate the crude and adjusted odds ratios and 95% confidence intervals for the association between different risk factors and transient and permanent CH. Results Out of the 680 participants, 364 (53.53%) were male. Family history of CH (OR = 5.09, 95% CI: 1.66–15.63), neonatal jaundice (OR = 3.89, 95% CI: 2.36–6.43) and parental consanguineous relation (OR = 2.19, 95% CI: 1.51–3.17) were associated with an increased risk of permanent CH. Likewise, the use of Betadine in pregnancy (OR = 4.87, 95% CI: 1.45–16.28), family history of CH (OR = 5.98, 95% CI: 2.04–17.48), neonatal jaundice (OR = 2.81, 95% CI: 1.75–4.52), parental consanguineous relation (OR = 3.86, 95% CI: 1.92–5.74), and gestational age at birth (OR = 3.2, 95% CI: 1.90–5.41) were identified as risk factors for transient CH. Conclusion Family history, neonatal jaundice, gestational age at birth, and Betadine usage in pregnancy are associated with CH.

Abstract
Considering the increasing rate of hospitalization due to the symptoms intensification, and the increasing trend of air pollution, this study aimed to determine the relationship between the amount of air pollutants and the incidence of cardiovascular disease leading to hospitalization. This case-crossover study was carried out on the data of admitted patients with cardiovascular disease such as hypertension, ischemic heart disease, and cerebrovascular disease in Urmia during 2011-2016. Weather data about air pollutants (NO2, PM10, SO2, and CO) were obtained from the meteorological department of Urmia. The data were coded for each patient and matched with the meteorological data for statistical modeling. The data were analyzed through STATA version 14. Conditional logistic regression was used to estimate the effects of air pollutants on cardiovascular disease adjusted to air temperature, relative humidity, and air pollutants. The final analysis was performed on 43,424 patients with cardiovascular disease using code I10-I99 including ischemic heart disease, hypertension, and cerebrovascular disease adjusted to air temperature and relative humidity. Of all pollutants, CO with each increase 10 μg/m3 had a meaningful relationship with the incidence of cardiovascular hospitalization. By selecting the window of exposure, 1, 2, and 6 days before admission, lag 6 (6 days) was the best estimation for exposure time in the patients with cardiovascular patients (OR 1.0056, CI 1.0041-1.007), and in the patients with ischemic heart disease (OR 1.000055, CI 1.000036-1.000075) and in the patients with hypertension (OR 1.000076, CI 1.00002-1.000132). Regarding cerebrovascular disease, no statistically significant association was observed. The results showed that only CO was associated with an increased risk of admission in patients with cardiovascular disease, ischemic heart disease, and hypertension, and there was no clear evidence for pollution effects on cerebrovascular diseases.

Abstract
Purslane (Portulaca oleracea L.) is the richest green leafy vegetable source of omega-3, especially alpha linolenic acid (ALA). Experimental studies have shown beneficial effects of purslane extract on liver enzymes. The aim of the present study was to examine the effect of purslane hydroalcohoic extract in patients with non-alcoholic fatty liver disease (NAFLD). In a randomized double-blinded clinical trial, 74 patients were randomly assigned to receive either 300 mg purslane extract or placebo capsules for 12 weeks. Compared with baseline, alanine aminotransferase (ALT) (-9 [-17, 0.50] mg/dl; p = .007), aspartate aminotransferase (AST) (-4 [-10, -0.50] mg/dl; p = .001), gamma glutamyltransferase (GGT) (-6.21 ± 9.85 mg/dL; p < .001), fasting blood glucose (FBG) (-8 [-11, -1.50] mg/dl; p < .001) insulin resistance (-0.95 ± 2.23; p = .020), triglyceride (-20 [-67.50, 3.50] mg/dl; p = .010), and low-density lipoprotein cholesterol (LDL-C) (-5 [-12, -1] mg/dl; p < .001) decreased significantly in the purslane group. At the end of study, no significant changes were observed in liver steatosis grade, insulin, liver enzymes, total bilirubin, lipid profile, and blood pressure between the two groups. The findings of our study show that purslane extract at the dose of 300 mg/day for 12 weeks has no significant effects on liver enzymes, lipid profile, and glycemic indices in patients with NAFLD.

Abstract
Background & Aim: Shared decision making belongs to the continuum between the two decision-making paradigms of the paternalistic perspective and the client’s complete independence. Various interventions, including the Question Prompt List have been developed to facilitate patients’ participation in counseling. This study aims to investigate the effects of question prompt list on shared decision making among cancer patients.
Methods & Materials: For this study, the researchers performed a systematic review of the manuscripts available in Embase, PubMed, Scopus, and Web of Science databases which were published until January 2021. And then, the eligible studies investigating the effect of question prompt list on shared decision making were included in the study. The quality of the studies was assessed using the Cochrane risk of bias tool.
Results: Two eligible papers were included in the study, and it was reported that question prompt list was provided before the patients’ consultation with the physician. Both studies have used OPTION 12 to measure shared decision making. The two articles reported that patient communication aid and question prompt list had no significant effect on improving shared decision making through OPTION 12.
Conclusion: The findings of this systematic review could not confirm the impact of using question prompt list on shared decision making. more preliminary studies are needed to answer the question expressed by this systematic review study.

Abstract
Background: Generalized anxiety disorder (GAD) often remains undiagnosed in patients with migraine, while comorbidity of GAD with migraine is associated with increased dysfunction and risk of chronic migraine. Generalized Anxiety Disorder Scale 7-item (GAD-7) and Generalized Anxiety Disorder Scale 2-item (GAD-2) are the commonly employed screening measures for generalized anxiety symptoms in different patient groups. The present study aimed to evaluate psychometric properties of the Persian version of GAD-7 and GAD-2 in migraine. Methods: In this cross-sectional study, patients were diagnosed with migraine headaches according to the International Classification of Headache Disorders, 3rd edition (ICHD-3); then they participated in the psychiatric diagnostic interview, and filled out GAD-7, GAD-2, Beck Anxiety Inventory (BAI), Headache Impact Test-6 (HIT-6), and Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1). The psychometric properties of GAD-7 and GAD-2 were examined using SPSS and LISREL. Results: Final samples were 186 patients with migraine that 83 patients received a diagnosis of GAD. Confirmatory factor analysis (CFA) indicated that the one-factor model of GAD-7 fit the data well. Internal consistency, test-retest, and Guttman split-half reliability of GAD-7 and GAD-2 were good. Significant correlation results, average variance extracted (AVE), and composite reliability (CR) supported the construct validity of the GAD-7. A score of ≥ 10 in GAD-7 and ≥ 3 in GAD-2 achieved satisfactory sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) (GAD-7: 92%, 90%, 88%, and 93%, respectively; GAD-2: 79%, 88%, 71%, and 91%, respectively). Conclusion: Our findings supported GAD-7 and GAD-2 for assessing GAD in patients with migraine. It seems that GAD-7 and GAD-2 accurately diagnosed GAD in this group of patients.

Abstract
BACKGROUND Literature shows that the consumption of Dietary Supplements (DS) is more common in Iran. This study aimed to explore the experiences of a sample of Iranian women regarding the factors influencing the use of DS. METHODS This qualitative content analysis study was conducted in Qods city, Tehran province, Iran from January to March 2020. Forty-two semi-structured in-depth interviews were performed with women. The participants were asked about their experiences about the determinants of the consumption of DS. After the first round of the interviews was done, we performed content analysis of the data and continued up to data saturation. RESULTS Two main themes including personal factors (with 5 subthemes including sociodemographic characteristics, perceived benefits of DS, history of illness, physiological conditions, and lifestyle factors) and socio-economic factors (with 3 subthemes including subjective norms, the price of food and commercial considerations of the sectors involved in the production and sale of DS) emerged as the experiences of the participants as to the intake of DS. CONCLUSIONS These variables may suggest areas which need to be focused on for performing more effective interventions to affect appropriate consumption of DS in Iran.

Abstract
BACKGROUND Domestic violence during pregnancy as one of the most common social problems and major challenges of health systems can affect the health of the mother and fetus. The study aimed to compare the two groups of intervention based on solution-focused counseling and control in terms of violence and quality of life amounts in women who had experienced domestic violence. METHODS A randomized controlled trial on 90 pregnant women was blocked into two intervention groups (n = 45) and a control (n = 45). The intervention group received six counseling sessions with a solution-focused approach. Study tool included conflict tactics scale (CTS- 2) and short form health survey (SF-36). The tools were completed once before the intervention and again 6 weeks after the end of the counseling sessions by the participants of both groups. The P-value less than 0.05 was considered statistically significant. RESULTS A total of 82/90 pregnant women were analyzed. The results showed that median and interquartile range (IQR) of physical, psychological and sexual violence significantly decreased in the intervention group than the control group (Ps = 0.001). Moreover, quality of life scores significantly improved in the intervention group compared to the control group (P = 0.001). CONCLUSION Solution-focused counseling could be an effective approach to reduce the amount of violence and increase the quality of life in women exposed to domestic violence.
