Abstract
PURPOSE Nutrient deficiency is one of the common complications in patients who undergo gastrectomy, especially those vitamins and minerals absorbed in the stomach or by substances in the gastric juice, such as vitamin B12. Hence, this systematic review and meta-analysis were conducted for the first time to investigate the prevalence of vitamin B12 deficiency and its symptoms in gastric cancer (GC) patients who underwent gastrectomy. METHOD PubMed, Scopus, Google Scholar, and Web of Science databases were searched to find related studies. After screening, studies were selected based on the abstract and title of related studies. The heterogeneity and inconsistency between studies were evaluated using Cochran's Q, I 2 tests. Egger's test analyzed publication bias for studies. A 95% confidence interval (95% CI) was used to estimate the overall prevalence of vitamin B12 deficiency. RESULTS Fourteen studies, including 2627 GC patients who underwent surgery, were included in the study. The mean age of the patients in this study was 61.2 ± 4.93 years. The pooled estimate of meta-analysis results showed that the prevalence of vitamin B12 deficiency after gastrectomy in patients with GC was 48.8% (95% CI:32.4, 65.2%, I 2 : 98.85, τ 2 = 0.05, Q (13) = 1127.8, P < 0.001). The most important symptoms were anemia, fatigability, cold feet or legs, numbness, and dizziness. CONCLUSION AND RECOMMENDATION Vitamin B12 deficiency has a high prevalence among patients who have undergone gastrectomy, and it is necessary to pay enough attention to treating these patients after surgery to prevent its complications.

Association between prenatal vitamin D deficiency with dental caries in infants and children: a systematic review and meta-analysis. BMC Pregnancy Childbirth 2024; 24:256. [PMID: 38589811 PMCID: PMC11000361 DOI: 10.1186/s12884-024-06477-0] [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: 10/08/2023] [Accepted: 04/01/2024] [Indexed: 04/10/2024] Open
Abstract
Prenatal vitamin D (PVD) is a vital micronutrient for dental caries (DCs). The association between prenatal vitamin D deficiencies (PVDD) and DCs in children has been conflicting in different reports. This meta-analysis aimed to investigate the association between PVDD and DCs in children for the first time. We searched PubMed, Scopus, Web of Sciences, Embase, and Scholar databases to find relevant studies based on mesh terms from 2000 to October 2023. This study was conducted based on the 2020 version of the PRISMA checklist. Cochran's Q and I2 tests were used to evaluate heterogeneity between studies. Egger's test was used to evaluate publication bias. The effect size of the association between PVDD and DCs was reported by the odds ratio (OR) at the 95% confidence interval (95% CI).Twelve studies, including 11,021 participants, were reviewed. The pooled prevalence of PVDD was estimated at 4353 (32%). The prevalence of DCs in children of mothers with and without PVDD was 44% and 25%, respectively. PVDD was significantly associated with an increased risk of DCs in children (OR: 1.35, 95% CI (1.22, 1.47), I2 = 86.6%). The association of DCs with PVDD was different based on gestational age groups, children's age groups, and vitamin D levels. This meta-analysis showed PVDD can be associated with an increased risk of DCs in children, especially in mothers with prenatal vitamin D levels ≤ 35 nmol/L. Adequate vitamin D levels throughout pregnancy can help prevent DCs in children.

Effect of Metformin Use on Survival and Recurrence Rate of Gastric Cancer After Gastrectomy in Diabetic Patients: A Systematic Review and Meta-analysis of Observational Studies. J Gastrointest Cancer 2024; 55:65-76. [PMID: 37526857 DOI: 10.1007/s12029-023-00955-y] [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] [Accepted: 06/24/2023] [Indexed: 08/02/2023]
Abstract
BACKGROUND Gastric cancer (GC) is one of the most common worldwide cancers and causes of death. Various studies have investigated the effect of metformin on overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and recurrence rate in diabetic patients after gastrectomy, and their results have been contradictory. This meta-analysis aimed to evaluate the effect of metformin use compared to sulfonylurea compounds with OS, CSS, RFS, and recurrence rate after gastrectomy in diabetic patients. METHODS We reviewed the Scopus, Google Scholar, PubMed, Web of Science, and Embassy databases until September 2022 based on appropriate MESH terms. All observational studies that evaluated the effect of metformin on survival in diabetic patients who underwent surgery for GC were included. The hazard ratio (HR) with a 95% confidence interval was used to estimate the effect size. The Egger test was used to evaluate publication bias. RESULTS Overall, nine studies, including 245,387 GC patients who underwent surgery, were included. The use of metformin significantly increased the OS rate (HR: 0.81, 95% CI: 0.78, 0.86, P: 0.001, I2: 4.5%), CSS rate (HR: 0.72, 95% CI: 0.63, 0.81, P: 0.011, I2 = 0%), and RFS rate (HR: 719, 95% CI: 0.524, 0.986, P: 0.001) and decreased the recurrence rate after gastrectomy (HR: 0.83, 95% CI: 0.77, 0.87, P: 0.001, I2: 0%). The use of metformin was significantly associated with a greater increase in OS and CSS rate and a greater decrease in recurrence rate in the Asian population than in the Western population. CONCLUSION The use of metformin in diabetic patients with GC can be associated with improved OS, CSS, RFS, and reduced recurrence rate after gastrectomy, especially in the Asian population.

[PMID: 38103456 DOI: 10.1016/j.ijotn.2023.101078] [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: 10/05/2023] [Revised: 12/04/2023] [Accepted: 12/07/2023] [Indexed: 12/19/2023]
Abstract
OBJECTIVE Many studies have reported conflicting results for the use of tramadol with the risk of fractures, especially hip fractures. This systematic review and meta-analysis study aimed to evaluate the association of tramadol use versus codeine use with the risk of hip fracture for the first time. METHODS PubMed, Scopus, Google Scholar, and Web of Science databases were searched with specific keywords to find studies that examined the association of tramadol use with hip fracture risk in patients with osteoarthritis up to May 2023. The risk of hip fracture secondary to tramadol versus codeine use was estimated based on age and sex. This systematic review was conducted based on the PRISMA checklist. Heterogeneity between studies was evaluated using Cochran's Q and I2 tests. Egger's test was used to check publication bias. The Newcastle-Ottawa Checklist (NOS) was used to assess the quality of the studies. FINDINGS Ten studies with 1,939,293 participants were reviewed. The majority of participants were female. Based on the study evaluation checklist, most studies were of good quality. Tramadol use significantly increases the overall risk of hip fracture. (HR: 1.32, 95% CI: 1.14, 1.51, P: 0.001, I2:19.3%) Tramadol use significantly increases the risk of hip fracture in men (HR: 1.48, 95% CI: 1.24, 1.73, P: 0.001 I2:35%) and age ≤65 years (HR: 1.63, 95% CI: 1.45, 1.80, P: 0.001, I2:0%). CONCLUSION The use of tramadol significantly increases the risk of hip fracture. This increased risk of hip fracture was greater in males younger than 65 years.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. The survival rate after hepatectomy as the first line of treatment for HCC depends on various factors. This study evaluated the association of the ABO blood group and Rh with overall survival (OS) and Recurrence-free survival (RFS) rate after hepatectomy. METHODS This multicenter retrospective cohort study reviewed the medical files of 639 HCC patients who underwent hepatectomy from 2010 to 2022 in three medical centers affiliated with the Iran University of Medical Sciences. Patient data, including demographic, clinical, tumor characteristics, and post-surgery outcomes, were collected by referring to the patient's medical profiles. The Cox proportional hazard investigated the relationship between ABO blood group type and OS and RFS rate after hepatectomy. RESULTS The five-year OS and RFS rates were 25.4% and 18.7%, respectively. The five-year OS (Lok rank:40.89, P:0.001) and RFS rate in patients with blood type A were significantly lower than in non-A patients. (Lok rank:10.8, P:0.001) The multivariate Cox analysis showed that blood type A, age < 45 years, tumor size > 5 cm, Poor tumor differentiation, presence of metastasis, The number of involved lymph nodes ≤ 2, and serum Alpha-Fetoprotein)AFP( level ≥ 400 were significantly related to the decreased survival rate of HCC patients after hepatectomy (P < 0.05) There was no significant association between Rh with OS and RFS (P > 0.05). CONCLUSION Blood group type A, compared to non-A, can be associated with decreased OS and RFS rates in patients with HCC after hepatectomy.

Abstract
BACKGROUND Various factors affect the survival rate of Gastric cancer (GC) patients after gastrectomy. This study aimed to investigate the effect of the number of negative lymph nodes (NLNs) removed on GC patients' survival and recurrence rate after gastrectomy. METHODS In this retrospective, multicenter cohort study, we reviewed the medical profile of 639 patients with a definite diagnosis of GC who underwent gastrectomy from 2010 to 2022 in one of the medical centers affiliated with the Iran University of Medical Sciences. Based on the number of NLNs removed, patients were divided into three groups, including (0-9NLNs), (10-15 NLNs), and (≥ 16 NLNs), including 155, 231, and 253 GC patients, respectively. Demographic characteristics, tumor characteristics, and pathological findings of the patients were extracted by referring to the patient's files. RESULTS The 5-year survival rate of patients was estimated at 48.2%. The 5-year tumor recurrence rate in patients with the number of NLNs 1-9, NLNs 10-15, and ≥ 16 NLNs were 79.4%, 51.1%, and 30.8%, respectively. (Log-rank = 9.24, P 0.001) The multivariate analysis showed that the 5-year survival rate in patients with fewer NLNs removed ≥ 16 was significantly higher than in the other two groups. In addition, age, BMI, tumor size, tumor stage, metastasis, and tumor differentiation were significantly related to the survival of GC patients after gastrectomy. (p < 0.05) CONCLUSION: Paying attention to the number of NLNs removed during gastrectomy can be a key factor in improving the survival prediction of GC patients.

Abstract
BACKGROUND Traditionally, the size of total knee arthroplasty (TKA) components is predicted by preoperative radiographic templating, which is of limited accuracy. This study aimed to evaluate the role of demographic data and ankle volume in predicting implant size in TKA candidates. METHODS In a retrospective study, 415 patients who underwent TKA at a single institution were included. The mean age of the patients was 67.5 ± 7.1 years. The mean BMI of the patients was 31.1 ± 4.7 kg/m2. TKA implants were Zimmer Biomet NexGen LPS-Flex Knee in all cases. The demographic data included age, sex, height, weight, BMI, ethnicity, and ankle volume. Ankle volume was assessed with the figure-of-eight method. Multivariate linear regression analysis was used for predicting factors of implant size. RESULTS Multivariate linear regression analysis showed that the Sex (β:1.41, P < 0.001), height (β:0.058, P < 0.001), ankle volume (β:0.11, P < 0.001), and Age (β:0.017, P = 0.004) were significant predictors of tibial component size. Sex (β:0.89, P < 0.001), height (β:0.035, P < 0.001), and ankle volume(β:0.091, P < 0.001) were significant predictors of femoral component size in the multivariate analysis. CONCLUSION Demographic data, adjunct with the ankle volume, could provide a promising model for preoperative prediction of the size of tibial and femoral components in TKA candidates.

Abstract
INTRODUCTION Recently, studies have investigated the relationship between blood types and cancers. Contradictory results regarding the relationship between blood group type and colorectal cancer(CC) have been reported. The purpose of this study was to systematically investigate the distribution of ABO blood group frequency and evaluate its relationship with CC. MATERIAL AND METHODS To conduct this systematic meta-analysis, we searched PubMed, Scopus, Web of Science, and Google Scholar databases using appropriate MESH terms until July 2022. All observational studies which assessed the ABO blood group frequency distribution and the association between ABO and CC were included. The Risk of Bias Assessment tool was used to assess the quality of studies. A random model was used to estimate the odds ratio (OR). The Egger test was used to assess the publication bias. RESULTS Overall,14 studies (413,132 patients) were included. According to the pooled estimation, blood groups A, B, AB, and O frequency in patients with CC were 37%,18%,9%, and 31%, respectively. The OR of CC in people with the A blood group was higher than in the other groups (OR: 1.11, 95% CI:1.03,1.19, P:0.001). In contrast, the OR of CC in people with the O blood group was significantly lower than in other blood groups (OR: 0.93, 95% CI:0.83,0.97, P:0.001). No significant relationship was observed for B and AB blood groups with CC. CONCLUSIONS This Meta-analysis showed that blood group type A has a greater risk of developing CC, while blood group type O was associated with lower chances of CC.

Abstract
INTRODUCTION Fecal incontinence (FI) is caused by external anal sphincter injury. Vitamin E is a potential strategy for anal sphincter muscle repair via its antioxidant, anti-inflammatory, anti-fibrotic, and protective properties against myocyte loss. Thus, we aimed to evaluate the water-soluble form of vitamin E efficacy in repairing anal sphincter muscle defects in rabbits. METHODS Twenty-one male rabbits were equally assigned to the intact (without any intervention), control (sphincterotomy), and Trolox (sphincterotomy + Trolox administration) groups. Ninety days after sphincterotomy, the resting and squeeze pressures were evaluated by manometry, and the number of motor units in the sphincterotomy site was calculated by electromyography. Also, the amount of muscle and collagen in the injury site was investigated by Mallory's trichrome staining. RESULTS Ninety days after the intervention, the resting and squeeze pressures in the intact and Trolox groups were significantly higher than in the control group (P = 0.001). Moreover, the total collagen percentage of the sphincterotomy site was significantly lower in the Trolox group than in the control group (P = 0.002), and the total muscle percentage was significantly higher in the Trolox group compared to the control group (P = 0.001). Also, the motor unit number was higher in the Trolox group than in the control group (P = 0.001). CONCLUSION Trolox administration in the rabbit sphincterotomy model can decrease the amount of collagen and increase muscle, leading to improved anal sphincter electromyography and manometry results. Therefore, Trolox is a potential treatment strategy for FI.

The use of metformin, sulfonylurea compounds and insulin and the risk of hip fractures in diabetic patients: a systematic review and meta-analysis of observational studies. BMC Musculoskelet Disord 2023; 24:367. [PMID: 37161384 PMCID: PMC10170842 DOI: 10.1186/s12891-023-06493-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 05/04/2023] [Indexed: 05/11/2023] Open
Abstract
BACKGROUND Hip fracture is a major health problem that occurs more often in the elderly, especially in diabetic patients. Some studies have been conducted regarding the effect of anti- diabetic drugs on fractures. But so far, no meta-analysis study has been conducted to investigate the effect of diabetic drugs on hip fractures. Therefore, this study investigated the relationship between anti-diabetic drugs (Metformin, Sulfonylurea, and insulin) with hip fractures. METHODS In this systematic review and meta analysis study, PubMed, Scopus, Google Scholar, and Web of Science databases were searched with specific keywords to find relevant studies. Two researchers included related studies after screening based on the title and full text. Cochran's Q and I2 tests were used to assess heterogeneity between studies. Publication bias between studies was evaluated for each drug using Egger's test. A 95% confidence interval was used for effect size significance. Overall, 49 studies, including 6,631,297 participants, were reviewed. RESULTS The results showed that metformin significantly reduced the risk of hip fracture (HR: 0.833, 95% CI: 0.759, 0.914, P:0.001). Consumption of sulfonylurea compounds was significantly associated with an increased risk of hip fracture. (HR: 1.175, 95% CI:1.068,1.293, P:0.001), The risk of hip fracture in patients receiving insulin was significantly higher than in diabetic patients who did not receive insulin. (HR:1.366, 95% CI:1.226,1.522, P:0.001). CONCLUSION The results of this study showed that taking metformin reduces the risk of hip fracture, and insulin and Sulfonylurea increase the risk of hip fracture.

Abstract
BACKGROUND Phobia as a psychological disorder seems to be aggravated during health crises like the current COVID-19 outbreak. On the other hand, people's knowledge about a situation can help decrease the resulting fear. STUDY DESIGN This is a cross-sectional analytical study to evaluate the COVID-19 related phobia and to measure knowledge, attitude, and practice of our target Iranian population about COVID-19. METHODS In this study, DSM-5 specific phobia questionnaire, adapted to SARS-CoV2-19 infection, was used to evaluate the COVID-19 related phobia. Moreover, the knowledge, attitude, and practice (KAP) questionnaire, specific for SARS-CoV-2 infection, was applied. RESULTS Phobia score was significantly higher in 1st-degree relatives of healthcare staff (20.38±5.82) than healthcare staff (18.36±5.68) (p=0.021). Females showed a significantly more severe phobia (20.27±5.41) than males (17.72±5.35, p=0.001). COVID-19 phobia was significantly more severe in those with past psy-chiatric conditions than in those without psychiatric history (p<0.05). The 1st-degree relatives of healthcare staff had a significantly lower level of knowledge about SARS-CoV-2 infection (8.19±1.65) than healthcare staff (9.08±1.28, p=0.001). Additionally, age had a positive significant correlation with knowledge and practice towards SARS-CoV-2 infection. CONCLUSION Both Iranian healthcare staff and 1st-degree relatives of healthcare workers are suffering from moderate COVID-19 phobia. Females are more concerned than males about COVID-19. Phobia is more severe in people with underlying psychiatric conditions than other people. The knowledge level of Iranian healthcare workers and 1st-degree relatives of healthcare staff about COVID-19 is acceptable but it needs improvement in certain areas.

Abstract
BACKGROUND Weight regain (WR) and insufficient weight loss (IWL) after sleeve gastrectomy (SG) are challenging issues. This study aimed to evaluate the predictors of WR and IWL after SG. METHODS In this retrospective analytical study, 568 patients who underwent SG at Hazrat-e Rasool General Hospital, Tehran, Iran, between January 2015 and April 2022 were evaluated. A total of 333 patients were included. WR and IWL were evaluated by multiple criteria such as a BMI of > 35 kg/m2, an increase in BMI of > 5 kg/m2 above nadir, an increase in weight of > 10 kg above nadir, percentage of excess weight loss (%EWL) < 50% at 18 months, an increase in weight of > 25% of EWL from nadir at 36 months, and percentage of total weight loss (%TWL) < 20% at 36 months. All participants were followed up for 36 months. RESULT The univariate analysis showed that preoperative BMI, obstructive sleep apnea, metformin consumption, and grades 2 and 3 fatty liver disease were associated with WR and IWL (P < 0.05). WR or IWL incidence varied (0-19.3%) based on different definitions. The multivariate analysis showed that a preoperative BMI of > 45 kg/m2 [odds ratioAdjusted (ORAdj) 1.77, 95% CI: 1.12-4.11, P = 0.038] and metformin consumption [ORAdj: 0.48, 95% CI: 0.19-0.78, P = 0.001] were associated with WR and IWL after SG, regardless of the definition of WR or IWL. CONCLUSION This study showed that preoperative BMI of > 45 kg/m2, obstructive sleep apnea, metformin consumption, and grades 2 and 3 of fatty liver disease were associated with WR or IWL.

Abstract
BACKGROUND Historically, Roux-en-Y gastric bypass (RYGB) has been considered the gold standard of bariatric surgery (BS). This procedure acts as a mixed restrictive and malabsorptive operation. METHODS This retrospective cohort study included 410 morbidly obese patients (BMI > 40 kg/m2 or BMI > 35 kg/m2 along with at least one major comorbidity) who underwent primary laparoscopic RYGB surgery from 2009 to 2015 by a single surgery team. The patients were 18 years and older with at least 12 months of follow-up. Total weight loss (%TWL) and comorbidity resolution were compared in short-term (12 months) and mid-term (12-60 months) follow-ups. The primary and secondary outcomes were evaluating the effect of Roux-en-Y on weight loss and control of comorbidities, respectively. RESULTS The mean ± SD age, weight, and BMI at surgery were 40.1 ± 10.58 years, 123.32 ± 19.88 kg, and 45.78 ± 5.54 kg/m2, respectively, and 329 (80%) were female, and 62 (15%) had T2DM. %TWL was significantly higher in T2DM patients 9 months postoperatively and after that. Patients with lower BMI (< 50 kg/m2) at surgery and non-diabetic patients had a significantly lower %TWL over a short- and long-term follow-up (P < 0.001). CONCLUSIONS BS remains the most efficacious and durable weight loss treatment. However, a proportion of patients will experience insufficient weight loss following BS.

Predictors of survival rate in patients with pancreatic cancer: A multi-center analytical study in Iran. Cancer Rep (Hoboken) 2022; 5:e1547. [PMID: 34494396 PMCID: PMC9351653 DOI: 10.1002/cnr2.1547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Revised: 08/17/2021] [Accepted: 08/19/2021] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Pancreatic cancer (PC) is among the deadliest cancers of the gastrointestinal tract worldwide and a growing global health concern. AIM This study was aimed to evaluate the survival rate and prognostic factors of survival in patients with PC. METHODS In this retrospective cohort study, the records of 556 patients with PC registered in the hospital cancer registration system from September 2007 to September 2020 were evaluated. In this regard, demographic data, tumor characteristics, received treatments, and patients' final status were analyzed. Kaplan-Meier and Cox's regression were used for univariate and multivariate analyses, respectively. RESULTS The 5-year survival rate was found to be 4.3%. The median survival time was 12.4 ± 6.6 months. Univariate analysis showed that age, BMI (kg/m2 ), blood transfusions, differentiation, tumor stage, tumor size, number of involved lymph nodes, lymph node ratio (LNR), and type of treatment received were significantly associated with patient survival (p < .05). Multivariate Cox regression indicated that the age ≥60 years [Hazard Ratio (HR) = 1.25, 95% confidence interval (CI) = 1.03-1.49], BMI <18 (kg/m2 ; HR = 1.56, 95% CI = 1.13-2.14), poor differentiation (HR = 2.12, 95% CI = 1.75-2.49), tumor size >2.5 cm (HR = 4.61, 95% CI = 3.30-6.78), metastasis presence (HR = 1.97, 95% CI = 1.49-2.60), more than two involved lymph nodes (HR = 1.52, 95% CI = 1.31-1.77), LNR <0.2 (HR = 0.56, 95% CI = 0.36-0.77), and adjuvant therapy with surgery and chemotherapy (HR = 0.44, 95% CI = 0.28-0.61) are the most important prognostic factors of survival in patients with PC (p < .05). CONCLUSIONS This study showed that the survival rate of patients with pancreatic cancer varies based on the characteristics of the tumor and the type of treatment received.

Coronavirus Disease 2019 (COVID-19) Infection-Related Stigma, Depression, Anxiety, and Stress in Iranian Healthcare Workers. Int J Prev Med 2022; 13:88. [PMID: 35958369 PMCID: PMC9362743 DOI: 10.4103/ijpvm.ijpvm_12_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 09/28/2021] [Indexed: 11/15/2022] Open
Abstract
Background Psychological conditions aggravate during outbreaks. Here, we have discussed the existing COVID-19 depression, anxiety, and stress and the resulting stigma and its different aspects in Iranian health care workers and their 1st-degree relatives. Methods In this cross-sectional study, information of our study groups (237 participants including health care workers and their nuclear family members) was collected via two online stigma and depression, anxiety, and stress scale (DASS) questionnaires. Results The DASS questionnaire's mean depression, anxiety, and stress scores were 13.59 ± 5.76, 11.07 ± 4.38, and 15.05 ± 5.86, respectively, in our study population. Marriage status was effective on depression and stress scores. Married participants were having less depression (P = 0.008) but more stressful (P = 0.029) than single ones. Education was found to be effective on anxiety and stress scores. Those with an associate, master, Ph.D., and higher college degrees were significantly less anxious and stressed than those with a diploma or bachelor's degrees (P = 0.032 and 0.016, respectively, for anxiety and stress). Participants with a history of psychiatric conditions showed significantly higher depression, anxiety, and stress rates than those without a past psychiatric condition (P = 0.001). Healthcare workers and their nuclear family members suffer from severe stigma (mean stigma scores were 33.57 and 33.17, respectively). Conclusions Healthcare workers and their nuclear family members in Iran suffer from severe COVID-19 related stigma. We also showed that depression, anxiety, and stress are common among Iranian Healthcare workers and their nuclear family members during this pandemic. This study showed that people with preexisting psychiatric conditions need extra mental care during the pandemic.

Evaluation of health-related quality of life before and after total hip arthroplasty in the elderly in Iran: a prospective cohort study. BMC Psychol 2022; 10:64. [PMID: 35287750 PMCID: PMC8922871 DOI: 10.1186/s40359-022-00762-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 02/23/2022] [Indexed: 11/10/2022] Open
Abstract
Background Owing to the direct impact of total hip arthroplasty (THA) on health-related quality of life (HRQOL) and the higher prevalence of THA in the elderly, this study aimed to compare HRQOL before, and after THA in the Iranian elderly.
Methods The present prospective cohort study was performed on 161 THA candidates. Demographic data were extracted from records of patients. Before, 6, and 12 months after THA, a Short Form 36 health survey (SF-36) was used to assess HRQOL. Before THA, 6 and 12 months after THA, Physical (PCS), and mental component scores (MCS) were obtained from a hundred separately for each subscale of the questionnaire. The Paired t-test was used to compare HRQOL before and after THA. Results Both 6 and 12 months after THA, HRQOL was significantly increased compared to previous THA (P = 0.001). In the first half-year after THA, vitality and emotional state were not different from pre-surgery. However, 12 months after THA, these two subscales also were significantly improved. Although, 6 months after THA, the PCS has dramatically gone up compared to the previous THA (P = 0.012), despite MCS was remained steady. Nonetheless, by comparison with the before surgery, 12 months after THA, MSC notably improved (P = 0.048). Conclusion HRQOL was appreciably improved by the THA in the elderly after 12 months. The improvement in HRQoL in the first 6 months after THA is related to the promotion in the physical aspect (PCS score), and in the second 6 months after THA is related to the promotion in the psychological aspect (MCS score).

Abstract
INTRODUCTION Rupture of renal angiomyolipoma (AML) is an emergency and life-threatening complication. This study aimed to evaluate the association of computed tomography (CT) scan parameters with the risk of rupture in renal AMLs. METHODS In this retrospective cross-sectional study, patients who were referred to a referral university hospital with diagnosis of AML, between 2007 and 2019, were included. Patients were divided into ruptured and non-ruptured cases based on surgery and CT scan findings and the baseline characteristics as well as CT scan parameters were compared between the two groups. RESULTS 20 AML patients with the mean age of 39.6 ± 12.5 years were included (75% female). The lesion was ruptured in 8 (40%) patients. The mean size of the lesion was 97.0 ± 15.9 mm in the ruptured and 72.0 ± 29.4 in the non-ruptured AML (p = 0.045). The mean fat density based on non-contrast enhanced CT (NCCT) scan (-56.1 ± 16.3 vs -74.9±24.1; p = 0.018) and contrast enhanced CT (CECT) scan (-20.8 ± 16.9 vs -50.5 ± 31.7; p = 0.016) was significantly higher in the ruptured cases. Total tumor density based on NCCT scan was significantly greater in the ruptured AMLs (19.6 ± 25.9 vs -22.7±41.6, p=0.033). CONCLUSION It seems that some CT scan parameters such as mean fat density and total tumor density could be used for differentiation between ruptured and non-ruptured AMLs.

Prevalence of anal fistulas: a systematic review and meta-analysis. GASTROENTEROLOGY AND HEPATOLOGY FROM BED TO BENCH 2022; 15:1-8. [PMID: 35611255 PMCID: PMC9123633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Accepted: 01/29/2022] [Indexed: 12/04/2022]
Abstract
Anal fistula refers to a clinical condition with local pain and inflammation associated with purulent discharge that affects the quality of life. Due to the lack of studies, the presence of bias, and high heterogeneity in the studies, the present systematic review is the first to be performed on the population-based database in this field. The present systematic review and meta-analysis was performed according to MOOSE guidelines. After systematic searching in electronic databases, only four articles met the inclusion criteria. After preparing a checklist and extracting data from the relevant articles, a meta-analysis was performed. All studies on the prevalence of anal fistula are related to Europe, and so far, no study has been conducted on other continents. The overall prevalence of anal fistula in European countries was 18.37 (95% CI: 18.20-18.55%) per 100,000 individuals, and the highest prevalence was reported for Italy (23.20 (95% CI: 22.82 to 23.59) per 100,000 people). From the present population-based (224,097,362) study results, it can be concluded that there is a prominent knowledge gap in this context. Because all the studies included in the current study relate only to Europe, the need for further research in this field in other countries is inevitably sensible.

Changes in Body Composition, Basal Metabolic Rate, and Blood Albumin during the First Year following Laparoscopic Mini-Gastric Bypass. J Obes 2022; 2022:7485736. [PMID: 35800664 PMCID: PMC9256454 DOI: 10.1155/2022/7485736] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 03/19/2022] [Accepted: 04/30/2022] [Indexed: 11/18/2022] Open
Abstract
Bariatric surgery is currently the only method that can significantly and continuously reduce weight and improve obesity-related comorbidities in morbidly obese patients. Significant weight loss through bariatric surgery can lead to changes in body composition. This study shows the changes in body composition, basal metabolic rate (BMR), and serum albumin in obese people following bariatric surgery. The study included 880 patients who underwent laparoscopic mini-gastric bypass surgery (LMGBP) between 2016 and 2020. The body mass index (BMI), bioelectrical impedance analysis (BIA), age, gender, blood albumin, WC (waist circumference), HC (hip circumference), BMR, and blood albumin were recorded at 0, 3, 6, and 12 months, postoperatively. The reduction in serum albumin concentration was not consistent with weight loss. Bariatric surgery promotes the breakdown of both fat and lean mass on the arms, torso, and thighs. This size reduction usually aggravates the concomitant skin redundancy in these areas which is a challenge for the plastic surgery team. Interestingly, the rate of lean mass reduction of the arms is faster than that of the torso and thighs. Excessive loss of lean body mass will also lower BMR and lead to subsequent weight gain. Despite the faster loss of proteins and lean mass in somatic areas, internal organs and viscera lose fats faster than proteins. According to this study, visceral proteins are the latest proteins to be affected by weight loss. This finding shows a different metabolic response of viscera comparing to somatic areas.

Abstract
Background Photobiomodulation with low-intensity laser (LIL) and chondroitinase ABC (ChABC) can repair damaged muscle tissue, so the aim of this study was to investigate the effect of co-administration of these two factors on anal sphincter repair in rabbits. Methods Male rabbits were studied in 5 groups (n = 7): Control (intact), sphincterotomy, laser, ChABC and laser + ChABC. 90 days after intervention were evaluated resting and maximum squeeze pressures, number of motor units, collagen amount, markers of muscle regeneration and angiogenesis. Results Resting pressure in the Laser + ChABC group was higher than the sphincterotomy, laser and ChABC groups (p < 0.0001). Maximum squeeze pressure in the all study groups was higher than sphincterotomy group (p < 0.0001). In the laser + ChABC and ChABC groups, motor unit numbers were more than the sphincterotomy group (p < 0.0001). Collagen content was significantly decreased in the laser (p < 0.0001) and laser + ChABC groups. ACTA1 (p = 0.001) and MHC (p < 0.0001) gene expression in the Laser + ChABC group were more than the laser or ChABC alone. VEGFA (p = 0.009) and Ki67 mRNA expression (p = 0.01) in the Laser + ChABC group were more than the laser group, But vimentin mRNA expression (p < 0.0001) was less than the laser group. Conclusion Co-administration of ChABCs and photobiomodulation with LIL appears to improve the tissue structure and function of the anal sphincter in rabbits more than when used alone.

How the Choice of Osteosynthesis Affects the Complication Rate of Intercalary Allograft Reconstruction? A Systematic Review and Meta-analysis. Indian J Orthop 2021; 56:547-558. [PMID: 35342531 PMCID: PMC8921354 DOI: 10.1007/s43465-021-00563-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Accepted: 11/01/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND There is no clear consensus on the optimal type of fixation in intercalary allograft reconstruction. In this study, we aimed to compare the rate of most common complications following the plate and nail fixation of the intercalary allograft. MATERIALS AND METHODS We searched PubMed, EMBASE, Web of Science, Scopus, and Cochrane Library. Studies in which the complication rate of the single bridging plate and intramedullary nail fixation was extractable were included. Studies that used extra procedures such as cementation and fibular vascular graft augmentation were excluded. The primary outcome was the fixation-specific rate of nonunion. Secondary outcomes were the fixation-specific rate of fracture, infection, and local recurrence. RESULTS In total, 13 studies with 431 reconstructions (352 reconstructions in the plate group and 79 reconstructions in the intramedullary nailing group) were included in this study. In the plate fixation, the rate of nonunion, fracture, infection and local recurrence was 12%, 11%, 11%, and 3%, respectively. In the intramedullary nail fixation, the rate of nonunion, fracture, infection, and local recurrence was 37%, 5%, 4%, and 0%, respectively. The rate of nonunion was significantly higher in the intramedullary nail group (OR = 6.34; 95% CI 2.98-13.49, P < 0.001). The rate of fracture, infection, and local recurrence was not significantly different between the two fixation methods. CONCLUSIONS Intramedullary nail is associated with a significantly higher rate of nonunion. Since the rate of other complications was not significantly different between the two osteosynthesis types, plate fixation could be considered as a better type of fixation.

Abstract
Introduction: The popularity of motorcycle riding in Iran is increasing. However, there is a lack of information about the safety of different motorcycle types. This study aimed to compare the severity of injury and trauma pattern between scooter (vespa) and street (standard) motorcycle riders. Method: In a prospective cohort study, a comparison of demographics, injury severity, trauma pattern, and clinical characteristics between 324 riders (162 Vespa and 162 standard motorcycles) admitted to emergency departments was undertaken. The risk factors associated with severe injuries in the two groups were also determined. An emergency medicine specialist determined the severity of trauma based on the abbreviated injury scale (AIS). Results: The Odds Ratio (OR) of severe injuries was significantly higher in the standard motorcycle riders’ group (OR: 3.09; 95% CI: 1.9-4.21; p: 0.013). The frequency of lower extremity fractures was significantly lower in the Vespa group (OR: 4.11; 95% CI: 2.01-6.25; p = 0.012). The frequency of admission to the intensive care unit was significantly higher in the standard motorbike riders’ group (OR: 1.64; 95% CI: 1.11-2.51; p = 0.033). The multivariate analysis indicated that motorcycle type, the speed at the time of the accident, use of helmet, and age of riders are the most important predictors of trauma severity in riders (p<0.05). Conclusion: The pattern of injury varies between standard and Vespa motorcycles. The standard motorcycle riders were prone to a higher risk of adverse outcomes such as severe injuries. Due to the particular structure of scooters, the rate of lower limb injuries was significantly lower than standard motorcycles.

Abstract
Background Dysplasia epiphysealis hemimelica (DEH) is a rare benign overgrowth generally affecting the epiphyses and short bones of the lower limbs. DEH in the elbow joint is extremely rare, and to date, only three cases of DEH have been reported in the radial head. Case presentation In this study, we report a case of DEH located in the radial head of the right elbow of a 10-year-old boy, which was presented with elbow pain and limited range of motion. In clinical examination, an asymmetrical enlargement was observed over the elbow. The lesion was resected surgically, and the patient’s symptoms resolved afterward. The histologic analysis of the lesion confirmed the diagnosis of DEH. Conclusion This report highlights the role of DEH in the differential diagnosis of elbow pathologies, particularly its differentiation from osteochondroma.

Abstract
Risk factors for clinical outcomes of COVID-19 pneumonia have not yet been well established in patients with underlying liver diseases. Our study aimed to describe the clinical characteristics and outcomes of COVID-19 infection among patients with underlying liver diseases and determine the risk factors for severe COVID-19 among them. In a retrospective analytical study, 1002 patients with confirmed COVID-19 pneumonia were divided into two groups: patients with and without underlying liver diseases. The admission period was from 5 March to 14 May 2020. The prevalence of underlying conditions, Demographic data, clinical parameters, laboratory data, and participants' outcomes were evaluated. Logistic regression was used to estimate the predictive factors. Eighty-one (8%) of patients had underlying liver diseases. The frequencies of gastrointestinal symptoms such as diarrhea and vomiting were significantly higher among patients with liver diseases (48% vs. 25% and 46.1% vs. 30% respectively, both P < 0.05). Moreover, ALT and AST were significantly higher among patients with liver diseases (54.5 ± 45.6 vs. 37.1 ± 28.4, P = 0.013 and 41.4 ± 27.2 vs. 29.2 ± 24.3, P = 0.028, respectively). Additionally, the mortality rate was significantly high in patients with liver disease (12.4% vs. 7%, P = 0.018). We also observed that the parameters such as neutrophil to leukocyte ratio [Odds Ratio Adjusted (ORAdj) 1.81, 95% CI 1.21-3.11, P = 0.011] and blood group A (ORAdj 1.59, 95% CI 1.15-2.11, P = 0.001) were associated with progression of symptoms of COVID-19. The presence of underlying liver diseases should be considered one of the poor prognostic factors for worse outcomes in patients with COVID-19.

Abstract
Background: Gastroesophageal reflux disease (GERD) is a common upper gastrointestinal disorder with a negative impact on the quality of life. This study was aimed to assess the effect of adding duloxetine to lansoprazole on the symptom and quality of life improvement in GERD patients. Materials and Methods: Seventy adult patients with a complaint of heartburn and regurgitation were enrolled in this randomized trial. Patients with a history of atypical symptoms, advanced systemic disease, medication-induced symptom, structural lesion in endoscopy, allergy to the medication, and unco-operative were excluded. The patients randomly (computer generated table) assigned in Groups A who received lansoprazole 30 mg plus placebo daily and Group B, in which duloxetine 30 mg daily replaced by placebo during 4 weeks. All of participants, care-givers, and outcomes assessors were blinded. Basic demographic data, symptom severity score, depression and anxiety Beck score, and quality of life questionnaire were recorded at the starting and ending of treatment. Results: Fifty-four patients have completed the study. The mean difference of Anxiety Beck score (13, 95% confidence interval [CI] [10–16], P = 0.001) and total raw score of quality of life (7, 95% CI [3.89–10.11], P = 0.043) were significantly improved in Group B. Complete and overall heartburn improvement rates were significantly better in Group B (odds ratio [OR] Adj: 2.01, 95% CI [1.06–2.97] and OR Adj: 1.31, 95% CI [1.05–1.57], respectively). Conclusion: We found that the combination of duloxetine and lansoprazole is a safe and tolerable regimen, and it can significantly improve anxiety, heartburn, coffee consumption, the quality of sleep, and life in patients who suffer from the symptoms of GERD.

Abstract
Background Hypertension, the most common comorbidity among coronavirus disease 2019 (COVID-19) patients, is accompanied by worse clinical outcomes, but there is lack of evidence about prognostic factors among COVID-19 patients with hypertension. We have come up with some prognostic factors to predict the severity of COVID-19 among hypertensive patients. In addition, epidemiologic, clinical and laboratory differences among COVID-19 patients with and without underlying hypertension were evaluated. Methods Medical profiles of 598 COVID-19 cases were analyzed. Patients were divided into two comparative groups according to their positive or negative history of hypertension. Then, epidemiologic, clinical, laboratory and radiological features and also clinical outcomes were compared. Results 176 (29.4%) patients had underlying hypertension. Diabetes was significantly higher in hypertensive group [72 (40.9%) vs 76 (18%)] (P-value: 0.001). Cardiovascular and renal disorders were significantly higher in hypertensive patients. (P-value: 0.001 and 0.013 respectively). In COVID-19 patients with hypertension, severe/critical types were significantly higher. [42(23.8%) vs. 41(9.7%)], (P-value: 0.012). In the logistic regression model, Body mass index > 25 (ORAdj: 1.8, 95% CI: 1.2 to 2.42; P-value: 0.027), age over 60 (ORAdj: 1.26, 95% CI: 1.08 to 1.42; P-value: 0.021), increased hospitalization period (ORAdj: 2.1, 95% CI: 1.24 to 2.97; P-value: 0.013), type 2 diabetes (ORAdj: 2.22, 95% CI: 1.15 to 3.31; P-value: 0.001) and chronic kidney disease (ORAdj: 1.83, 95% CI: 1.19 to 2.21; P-value: 0.013) were related with progression of COVID-19. Conclusion Hypertensive patients with Age > 60-year-old, BMI > 25 Kg/m2, CVD, diabetes and chronic kidney disease are associated with poor outcomes in those with COVID-19 infection.

Abstract
OBJECTIVE: Helicobacter Pylori (H. pylori) treatment may be different depending on the host and microbial factors in each region. The study was planned to estimate the effect of two 10-day esomeprazole containing clarithromycin and levofloxacin sequential therapies on H. pylori treatment. MATERIALS AND METHODS: Totally, 186 H. pylori-infected patients with gastro-duodenal ulcer who had not yet received treatment for infection, were enrolled. We randomly designated patients to group A (N = 94) who treated with esomeprazole 40 mg and amoxicillin 1 g bid during the early half of treatment, and continued the same dose of esomeprazole with levofloxacin 500 mg and tinidazole 500 mg bid during the second half of treatment and Group B (N = 92) who treated with the identical treatment excepting clarithromycin 500 mg bid as a substitute of levofloxacin. To assess eradication, C14-urea breath test was implemented 8 weeks afterward treatment. RESULTS: Finally, 172 patients completed the trial. We calculated 85.1% (95% confidence interval [CI] = 77.9–92.3) and 83.7% (95% CI = 76.2–91.2) eradication intention-to-treat analysis (P = 0.302) and so, 93.0% (95% CI = 87.6–98.4) and 90.0% (95% CI = 83.6–96.3) eradication by per-protocol analysis (P = 0.420) for Group A and B, respectively. No significant difference was seen among regimens. Drug adverse reactions were not significantly different between regimens. Group A had a 97.8% adherence rate to treatment and Group B had 98.9%. CONCLUSIONS: Both esomeprazole containing sequential regimens including levofloxacin and clarithromycin showed good eradication rates in spite of significant differences in antimicrobial resistance patterns in vitro. The efficacy of esomeprazole in lowering gastric acidity beside its antimicrobial effect should be considered in H. pylori regimens.

Evaluation of the role of reflux pattern in Color Doppler Ultrasound on spermogram improvement after varicocelectomy. Int Urol Nephrol 2020; 52:2245-2251. [PMID: 32862328 DOI: 10.1007/s11255-020-02566-z] [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: 05/16/2020] [Accepted: 07/07/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Many attempts are being made to find an association between varicocele characteristics and sperm parameters. In this study, we investigated the association between a newly introduced varicocele reflux grading pattern and sperm parameters, as well as its effect on spermogram improvement after varicocelectomy. METHODS In a prospective study, 73 patients with a clinical single-sided varicocele who underwent corrective varicocelectomy were included. Reflux pattern was determined on Color Doppler Ultrasound (CDUS) and categorized into four grades: grade 1 (retrograde), grade 2 (augmentation), grade 3 (enhancement), and grade 4 (stasis). The association of pre- and postoperative spermogram with the patients' reflux pattern was evaluated. RESULTS A significant positive association was found between the venous diameter and reflux pattern. Higher grades of the reflux pattern were associated with the more severe hemodynamic pattern of the reflux (shunt type). A significant association was found between the reflux pattern and preoperative semen characteristics, and this association was more prominent in constant venous diameter. In this respect, the enhancing reflux type was associated with the most impaired preoperative sperm count, motility, and morphology. The enhancing type also revealed the most improvement in spermogram after varicocelectomy. CONCLUSION Patients with a higher reflex grade, particularly enhancing pattern, will most benefit from the surgical correction of varicocele. These findings suggest reflux pattern as a promising prognostic factor for a favorable outcome after varicocelectomy.

A randomized controlled trial of pegylated interferon-alpha with tenofovir disoproxil fumarate for hepatitis B e antigen-negative chronic hepatitis B: A 48-week follow-up study. J Infect Chemother 2020; 26:1265-1271. [PMID: 32762882 DOI: 10.1016/j.jiac.2020.07.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 07/03/2020] [Accepted: 07/16/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Recent studies report incongruent finds regarding the addition of pegylated interferon -alpha (Peg- IFNα) to nucleos(t)ide analogues. This study was designed to compare the efficacy of Peg- IFNα and tenofovir disoproxil fumarate (TDF) combination therapy with each of the treatments separately. METHODS In this open-label, randomized clinical trial, treatment-naive hepatitis B e antigen (HBeAg)-negative patients were randomly assigned to three treatment groups: Group A: Peg- IFNα (180 mcg/week) with TDF (300 mg/day); Group B: TDF (300 mg/day); and Group C: Peg- IFNα (180 mcg/week). The intervention spanned 48 weeks and patients were followed up every 12 weeks. The primary end-point was HBV DNA load <20 IU/mL. RESULTS Groups A, B and C each comprised of 22, 23 and 22 patients, respectively. The number of patients with HBV DNA suppression in group A was significantly higher compared to groups B and C (P = 0.034). No significant difference was observed in the normalization trends of serum ALT levels between the three groups (P = 0.082). At week 48, combination therapy was significantly more effective in suppressing HBV DNA concentration to below the level of detection than TDF monotherapy (OR = 2.1, 95%CI: 1.18-4.15; P = 0.034). Furthermore, a comparison between monotherapy arms revealed that both interventions had similar effects on the overall outcome (OR = 1.24, 95%CI: 1.02-5.8; P = 0.062). CONCLUSION A Peg- IFNα and TDF combination therapy resulted in improved virologic response and was safe in HBeAg negative patients. Monotherapy with Peg-IFNα or TDF procured limited benefits in comparison. TRIAL REGISTRATION This study was registered in the Iranian Registry of Clinical Trials (IRCT20181113041635N1).

Abstract
BACKGROUND Gastric cancer (GC) has been considered as the 5th most common type of cancer and the third leading cause of cancer-associated death worldwide. The aim of this historical cohort study was to evaluate the survival predictors for all patients with GC using the Cox proportional hazards, extended Cox, and gamma-frailty models. METHODS This historical cohort study was performed according to documents of 1695 individuals having GC referred to three medical centers in Iran from 2001 to 2018. First, most significant prognostic risk factors on survival were selected, Cox proportional hazards, extended Cox, gamma-frailty models were applied to evaluate the effects of the risk factors, and then these models were compared with the Akaike information criterion. RESULTS The age of patients, body mass index (BMI), tumor size, type of treatment and grade of the tumor increased the hazard rate (HR) of GC patients in both the Cox and frailty models (P < 0.05). Also, the size of the tumor and BMI were considered as time-varying variables in the extended Cox model. Moreover, the frailty model showed that there is at least an unknown factor, genetic or environmental factors, in the model that is not measured (P < 0.05). CONCLUSIONS Some prognostic factors, including age, tumor size, the grade of the tumor, type of treatment and BMI, were regarded as indispensable predictors in patients of GC. Frailty model revealed that there are unknown or latent factors, genetic and environmental factors, resulting in the biased estimates of the regression coefficients.

Abstract
Background In the current diagnostic procedure, generally, both plain radiographs and 3D-CT scans are used for the diagnosis of acetabular fractures. There is no consensus regarding the value of a three-dimensional computerized tomographic (3D-CT) scan alone in the classification of acetabular fractures. In this study, we compared the accuracy of 3D-CT scan and plain radiography through the evaluation of their agreement with the intraoperative surgeon’s classification. Method In a retrospective study, patients who were referred to our center with an acetabular fracture and underwent surgical treatment were included. The classification of acetabular fractures was performed once using Judet view plain radiographs and once using a 3D-CT scan by the corresponding one Experienced musculoskeletal radiologist one independent trauma fellowship-trained orthopaedic who routinely treat acetabular fractures and based on Letournel and Judet classification (17 and 23 years of experience respectively). Cohen’s kappa value was used for the assessment agreement between the two imaging modalities, as well as between the imaging modalities and intraoperative classification. Results Medical files of 152 patients with acetabular fracture were retrospectively reviewed. A kappa value of 0.236 was obtained as the agreement level between radiographs and intraoperative findings (p < 0.001). A kappa value of 0.943 was obtained as the agreement level between 3D-CT and intraoperative classification (p < 0.001). An agreement level of 0.264 was found between the Judet radiographs and 3D-CT scans (p < 0.001). Conclusions 3D-CT scans are reliable enough in the classification of acetabular fractures, and plain radiographs could be omitted to avoid radiation exposure as well as to reduce the cost for patients who sustain acetabular fractures.

Abstract
BACKGROUND A variety of medical and non-medical treatments have been introduced for functional constipation relief. Here, we aimed to compare the efficacy of a combination of polyethylene glycol (PEG) and abdominal massage with each one of the treatments alone. MATERIALS AND METHODS Patients with functional constipation based on Rome IV criteria were randomly assigned into the three treatment groups: group A (abdominal massage for 15 min daily), group B (PEG 20 g daily), and group C (PEG 20 g plus abdominal massage for 15 min daily) for 14 days. PAC-QOL questionnaire, Bristol stool scale were evaluated at baseline and two weeks after treatment. Constipation-associated symptom scores were recorded at baseline, two weeks and four weeks after treatment beginning. Descriptive statistics were provided as the mean ± standard deviation or number and percentage. P-value<0.05 was considered statistically significant. RESULTS Forty eight, 47 and 48 patients in group A, B, and C completed the study, respectively. PAC-QOL, Bristol and Constipation-associated symptom scores showed a significant improvement in all study groups two weeks after the treatment compared to the baseline. At the end of treatment, the rate of straining, incomplete evacuation sensation, finger evacuation and the number of defecation was significantly lower in the group C (P < 0.04). Bristol score were significantly improved in group B (P = 0.029) in compare to other groups. The total quality of life score was also significantly improved in the group C (P = 0.028). CONCLUSION A combination of abdominal massage and PEG is safe, tolerable and more effective than each one of the treatments alone.

Abstract
Biofeedback is a well-known and effective treatment for patients with fecal evacuation disorder (FED). The main purpose of this study was to investigate the outcome and the effects of biofeedback therapy on physiological parameters as assessed by manometry in patients with FED. Data from 114 consecutive patients with FED who underwent biofeedback therapy in Sara Gastrointestinal clinic in Tehran, Iran during 2015-2018 were retrospectively reviewed and analyzed. All participants underwent a comprehensive evaluation of anorectal function that included anorectal manometry and a balloon expulsion test at the baseline and after biofeedback therapy. Maximum anal squeeze pressure and sustained anal squeeze pressure were improved up to 100% and 94.7% of normal values in the patients after biofeedback, respectively (P < 0.001). First rectal sensation, was significantly decreased (25 ± 18.5 vs. 15.5 ± 5.2) while the maximum tolerable volume was significantly increased (233.6 ± 89.7 vs. 182.4 ± 23.1) after biofeedback therapy (P < 0.001). Type I dyssynergia was the most common type, effecting 82 cases (71.9%) of our patients. Dyssynergia parameters were improved 50-80% in 34 (41.5%) and 10 (31.3%) type I and non-type I patients, respectively. Over 80% improvement of dyssynergia parameters occurred in 48 (58.5%) and 22 (68.8%) type I and non-type I patients, respectively. These differences were not statistically significant between the two groups (P = 0.3). In addition, the ability to reject the balloon was significantly better in post intervention measurements (P < 0.001). Biofeedback not only improves the symptoms in patients of FED but also reverses more than 80% the dyssynergic parameters of defecation. However, due to the general effectiveness of biofeedback treatment in different types of DD, there were no significant differences between their improvement scores.

Abstract
INTRODUCTION Currently, the basis of acute coronary syndrome (ACS) therapy is dual antiplatelet therapy (DAPT) with Aspirin as a nonsteroidal anti-inflammatory drug and clopidogrel as adenosine diphosphate receptor antagonists. Therefore, the aim of the present systematic review is to answer that should DAPT with Aspirin and clopidogrel be continued until coronary artery bypass grafting (CABG) in patients who have ACS? METHODS The search for relevant studies in the present meta-analysis is based on three approaches: A) systematic searches in electronic databases, B) manual searches in Google and Google Scholar, and C) screening of bibliography of related original and review articles. The endpoints included mortality rate, myocardial infarction (MI), cerebrovascular accident (CVA), reoperation, re-exploration, other cardiac events, renal failure, length of ICU and hospital stay, chest tube drainage and blood product transfusion after CABG. RESULTS After the initial screening, 41 articles were studied in detail, and finally the data of 15 studies were included in the meta-analysis. DAPT before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events, but increases reoperation, re-exploration, length of ICU, and hospital stay. Chest tube drainage and blood product transfusion rate significantly increased in the DAPT group compared to the control group (non-antiplatelet or Aspirin alone). Increase in chest tube drainage and blood product transfusion rate indicates an increase in bleeding, so increase in reoperation, re-exploration to control bleeding, and, subsequently, increase in the length of ICU and hospital stay are expected. CONCLUSIONS DAPT with Aspirin and clopidogrel before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events despite more bleedings, and it may be suggested before CABG for better graft patency.

Abstract
Background: Child mortality surveillance system (CMSS) for children aged 1–59 months is a critical issue in the prevention of mortality. This surveillance system like other health programs needs to be evaluated. Therefore, this study aims to evaluate CMSS in Iran. Methods: This evaluation was performed from March 2015 to March 2016 based on selected criteria for assessing the public health surveillance system proposed by the Centers for Disease Control and Prevention. Selected criteria examined in this study included timeliness, simplicity, acceptability, and flexibility. These criteria were evaluated in two ways. First, it included the use of a researcher-made questionnaire. The questionnaires were completed by 100 experts on CMSS. Second, to perform a more exact evaluation of these criteria, 24 of these experts were selected for the focus group. Results: In this study, the response rate was 91% (42% hospital-based and 49% primary care-based). In the timeliness section, 49% of the experts believed that approvals of the child mortality committees have not been sent within the designated time frame; hardware, software, and questionnaires were reported as effective factors in this respect. The structural and administrative problems were effective in simplicity domain and the experts of mortality registration and mood of relatives were effective in acceptability domain. The flexibility of the system was high and appropriate. Conclusions: The findings of the present study reveal that CMSS has some limitations and problems in the timeliness, simplicity, and acceptability criteria, which can be resolved. But this program has an appropriate situation in terms of flexibility.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most common primary hepatic malignancies and growing challenges of global health. In this study, for the first time in Iran, we investigated the 5-year survival rate and prognostic factors in patients with HCC. Materials and Methods In this historical cohort study, we examined the medical records of 227 HCC patients who were registered in the central tumor registry of our institution from September 2007 to September 2017. Demographic data, clinical parameters, received treatments, and survival curves from time of diagnosis were evaluated. Kaplan-Meier was used for univariate analysis, and multivariable analysis was performed by Cox regression. Results A total of 208 (91.63%) patients were dead. The 5-year survival rate was estimated 19 (8.37%). The average follow-up in this study was 14.3 months. Overall median survival rate was 12.1 months. Univariate analysis showed that tumor size, metastasis, number of involved lymph node, hepatitis type, and treatment were significantly related to the survival rate, and Cox regression analysis revealed that the tumor size >3 cm (hazard ratio [HR] = 3.06, 95% confidence interval [CI] = 1.68-4.97; P = 0.027), involved lymph nodes >2 (HR = 4.12, 95% CI = 2.66-6.38; P = 0.001), metastasis (HR = 3.87, 95% CI = 3.13-6.54; P = 0.011), combination therapy with surgery and chemotherapy (HR = 0.4, 95% CI = 0.15-0.79; P = 0.023), and coinfection with hepatitis B virus and hepatitis C virus (HR = 2.11, 95% CI = 1.81-4.6; P = 0.036) are the most relevant prognostic factors with 5-year survival rate in patients with HCC. Conclusion Results of this study will help estimate survival rates for patients with HCC according to their clinical status.

Abstract
Background and aims: Hepatitis B virus (HBV) is one of the important public health diseases in Iran. Therefore, to control the prevalence of the disease, knowledge is required regarding the risk factor of HBV. Accordingly, the aim of this study was to determine the risk factors of HB transmission. Methods: A retrospective case-control study was conducted on the possible risk factors of HBV transmission. To this end, a total of 171 patients with HBV infection and 171 controls from Rasoul-eAkram hospital were investigated during 2015-2018. All subjects were directly evaluated using a faceto-face questionnaire about demographic aspects. Finally, HBV infection and its risk factors among the subjects were detected using hepatitis B surface antigen test. Results: Overall, 171 HBV patients including 77 (42%) males and 93 (58%) females were evaluated. The mean age of the participants was 40 ± 13 years. Univariate logistic analysis showed that HBV infection in these cases was associated with addiction injection (odds ratio [OR] = 4.08, CI:1.3- 9.57), family history (OR = 4.52, CI: 1.27-10.7), and having a history of blood transfusion (OR = 3.16, CI: 1.52-5.37). There were no significant relationships between the liver function tests, alcohol consumption, the history of dental visits, and HBV participants. In addition, the logistic-regression model proved that patients with a history of HBV-infected parents (At least one of them) and addiction injection were severely subject to HB infection. In other words, there was a significant association between a history of HBV-infected parents and addiction injection and HB infection. Conclusion: In general, HBV infection was strongly related to having a family member infected with hepatitis B, suffering from addiction injection, and having blood injection.

Abstract
Introduction: Hepatitis C virus (HCV) infection affects almost 180 million people around the world. Even though the development of direct acting antivirals (DAAs) has significantly improved the treatment responses to HCV infection, treatment with pegylated interferon (PegIFN) in combination with ribavirin is considered the standard of care (SOC) for chronic HCV infection treatment in countries with limited medical resources. Considering the inhibitory effect of vitamin B12 on HCV replication, we have evaluated the effect of vitamin B12 supplementation along with SOC on treatment outcomes in patients with chronic HCV infection, who were antiviral treatment-naive.
Methods: In this regard, seventy-four HCV-infected patients, naïve to antiviral therapy, were randomly assigned to receive SOC or SOC in addition to vitamin B12 (SOC + B12). Viral response was evaluated at 4, 12, 24 and 48 weeks following the initiation of viral treatment and at 24 weeks after completing the treatment. Genotyping of the interleukin 28B (IL28B) polymorphisms was also performed. Demographic characteristics, clinical findings, fibroscan results and drug adverse effects were recorded.
Results: Our findings showed that rapid viral response was not significantly different between the two groups; however, the rates of complete early viral response (cEVR) (p=0.033), end-of-treatment viral response (ETVR) (p=0.001) and sustained virologic response (SVR) (p=0.0001) were significantly higher in SOC + B12 patients compared to SOC patients. Besides, in SOC + B12 patients, those with a higher baseline viral load and carriers of IL28B CC genotype showed significantly higher rate of SVR.
Conclusion: In conclusion, the addition of vitamin B12 significantly improved the rate of SVR in HCV-infected patients, who were naïve to antiviral therapy. As this treatment regimen is safe and inexpensive, it proposes an option for improving the effectiveness of the HCV treatment with SOC, particularly in resource-limited settings.

Abstract
Background As the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention. Yet, the results considerably vary between studies. Here, we evaluate the HRQoL of the patient after THA, for the first time in the Iranian population. Methods In a case-control study, HRQoL was assessed in 217 patients after THA and compared with a matched reference population. The 36-item short-form health survey (SF-36) was used for the evaluation of HRQoL. A multiple linear regression model was used to investigate the influence of sociodemographic and clinical characteristics of the patients on the HRQOL. Results The mean follow-up of the patients was 27 ± 18 months. The mean total SF-36 score was 41.4 ± 22.2 in the case and 67.3 ± 26.6 in the control group (p = 0.001). The mean physical component score, but not the mental component score, was significantly lower in the patient group (p = 0.001). Except for the vitality and emotional role, all other SF-36 subscales were significantly lower in the case group. Male sex (B = 4.52, p = 0.023), number of comorbidities (B = − 4.82, p = 0.011), body mass index (B = − 1.18, p = 0.044), number of post-operative complications (B = − 6.57, p = 0.001), and adherence to physiotherapy protocol (B = 2.09, p = 0.014) were associated with HRQoL after THA. Conclusion Although THA is considered as one of the most successful orthopedic practices, it is associated with remarkable reduced HRQoL in Iranian population when compared with the reference population. A variety of patients-associated factors influence the HRQoL after THA.

Abstract
Introduction: Currently breast (BC) cancer is a serious medical problem in all countries of the world. Survival depends on many factors. The present study focused on 5-year survival and its related factors in patients with BC in Iran. Material and methods. The present analytical retrospective study was performed (from March 2010 until March 2015) on patients with BC followed for at least 6 months. The main variables assessed were tumor size, grade of lymph node involvement, metastasis, stage, history, human epidermal growth factor receptor expression, and tumor origin. Analysis of survival was accomplished using the Kaplan- Meier method. Results: Some 351 (80.2%) of the total of 438 individuals had unilateral and 87(19.8%) had bilateral cancer, 28 (35.6%) of the latter being synchronous and 56(64.4%) metachronous. Mean duration of follow-up was 47.44±28.19 months, during which 61 (17.3%) patients with unilateral and 18 with bilateral cancer eventually died. The 5-year survival rate in patients with unilateral BC was significantly higher than those with bilateral BC (Log-rank Test chi2= 3.11, p=0.032). In addition, with metachronous cases, the survival rate was 64.2% in comparison with 51.6% for synchronous BCs. Survival rate was significantly (p value =0.038) higher with metachronous than with synchronous cancers (Log-rank Test chi2=3.54, p=0.038). The highest survival rate was reported for BCs originating from lobule tissue and the lowest rate examples of interstitial tissue origin (Log-rank Test chi2=11.54, p=0.0001). Patients with earl stage lesions (M1) survived longer than with other stages (Log-rank Test chi2= 9.55, p=0.001). Conclusion: In this study, most women with BC had a positive family history and were married. The 5-year survival rate was lower with advanced stages of cancer. According to our findings, survival rates might improve if patients undergo screening and diagnosis is made at an early stage of the disease.

Abstract
Introduction: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. Treatment can improve symptoms and social functioning in the patients. This study was designed to assess the effect of adding Luvos supplementation to mebeverine on improving symptoms and quality of life (QOL) in patients with diarrhea-predominant irritable bowel syndrome.
Methods: Eighty patients with diarrhea-predominant IB, ages 18-65, were diagnosed by the Rome IV criteria and randomly assigned to the study. Forty patients (group A) received mebeverine (135 mg) twice a day (bid) plus Luvos®Healing Earth (1 sachet, bid). The other 41 patients (group B) received mebeverine (135 mg) bid for 4 weeks. Basic demographic data, Bristol score, symptom severity score, and QOL questionnaire were recorded at the start and completion of treatment. The data were analyzed by SPSS version 22.
Results: Seventy one of the patients (35 and 36 patients in groups A and B, respectively) completed the study. The majority of the patients were young males, unmarried and highly educated. Diarrhea and QOL were both significantly improved in group A when compared to group B (P=0.036 and P=0.028, respectively). We did not find a significant difference (improvement) in abdominal pain or overall symptom score between group A (mebeverine + Luvos) compared to group B (mebeverine alone) (P=0.096 and P=0.071, respectively). Mild and tolerable adverse effects were observed in 2.8% (2/71) of the patients.
Conclusion: According to our results, Luvos supplementation is safe, effective and well-tolerated in diarrhea-predominant irritable bowel syndrome patients. Further study with a larger sample size is recommended to evaluate the efficacy of this natural clay-like medicine.

[PMID: 28780229 DOI: 10.1016/j.dsx.2017.07.035] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2017] [Accepted: 07/21/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Helicobactor pylori (H. pylori) have the potential role in the pathogenesis of various extra-gastric disorders such as metabolic disorders. But, it is now questioned about whether H. pylori eradication reduces or induces the risk for metabolic disorders especially in patients with dyspepsia. Hence, the present study aimed to assess the effects of H. pylori eradication on criteria of metabolic syndrome. METHODS H. pylori infected patients with dyspepsia were included. The patients were treated with omeprazole (20mg, q12h), amoxicillin (1g, q12h), and clarithromycin (500mg, q12h) for two weeks, then H. pylori eradication was evaluated by C14 Breathing test (UBT) 6 weeks after the end of the treatment. Demographic data, clinical manifestation and metabolic parameters were recorded before and three months after completing treatment regimen. The data was analyzed by SPSS version 16.0. RESULTS Of 110 patients were initially enrolled, 91 patients completed the study. Overall eradication rate was 61.5%. Significant differences in the serum level of total cholesterol(180.7±34 vs. 172.1±28, p=0.001), LDL(107.0±25 vs. 100.8±20, p<0.001), HDL(46.2±8.7 vs. 48.9±8.6, p<0.001), fasting blood sugar (93.7±12 vs. 90.9±10, p=0.001), hemoglobin A1c(5.37±0.52 vs 5.25±0.53, p=0.006), and as well as for waist circumference(92.2±14 vs. 91.4±13.9, p=0.03) was found after treatment. Data for body weight, systolic and diastolic blood pressure and triglyceride level remained without any significant changes. CONCLUSION H. pylori eradication could relatively reduce the risk of metabolic syndrome criteria such as fasting blood sugar, hemoglobin A1c, lipid profile and waist circumference.
