The effect of calorie-restriction along with thylakoid membranes of spinach on the gut-brain Axis Pathway and oxidative stress biomarkers in obese women with polycystic ovary syndrome: a Randomized, Double-blind, placebo-controlled clinical trial

BACKGROUND

Women with polycystic ovary syndrome (PCOS) have higher intestinal mucosal permeability, leading to the lipopolysaccharide (LPS) leakage and endotoxemia. This, in turn, leads to oxidative stress (OS) and neuro-inflammation caused by the gut-brain axis, affecting the neurotrophic factors levels such as brain-derived neurotrophic factor (BDNF) and S100 calcium-binding protein B (S100 B) levels. In this study, it was hypothesized that the thylakoid membranes of spinach supplementation along with a hypocaloric diet may have improved the LPS levels, neurotrophic factors, and OS in PCOS patients.

METHODS

In this double-blind, randomized, placebo-controlled, and clinical trial, 48 women with obesity and diagnosed with PCOS based on Rotterdam criteria were randomly assigned to thylakoid (N = 21) and placebo groups (N = 23). A personalized hypocaloric diet with 500 calories less than the total energy expenditure was prescribed to all patients. The participants were daily supplemented with either a 5 g/day thylakoid-rich spinach extract or a placebo (5 g cornstarch) for 12 weeks along with a prescribed low-calorie diet. Anthropometric measurements and biochemical parameters were assessed at baseline and after the 12-week intervention.

RESULTS

A statistically significant decrease in the LPS levels (P < 0.001) and an increase in the BDNF levels (P < 0.001) were recorded for the participants receiving the oral thylakoid supplements and a low-calorie diet. Furthermore, significant decreases were observed in fasting blood glucose, insulin, homeostatic model of assessment for insulin resistance, free testosterone index, and follicle-stimulating hormone / luteinizing hormone ratio in both groups (P < 0.05). No significant differences were detected between the two groups regarding the changes in malondialdehyde, catalase, total antioxidant capacity, and S100B levels (P > 0.05).

CONCLUSIONS

In sum, the thylakoid membranes of spinach supplemented with a hypocaloric diet reduced the LPS levels, increased the BDNF levels, and improved the glycemic profile and sex-hormone levels; however, they had no effects on the OS markers levels after 12 weeks of intervention.

The Effect of Decision Aid on Satisfaction With Decision and Anxiety Among Women With Abnormal Cervical Screening Results

BACKGROUND

Most women in the face of stressful situations such as risk of a cancer diagnosis (abnormal Papanicolaou smear results) need guidance to choose the appropriate method to follow the diagnosis process, but few studies have identified appropriate interventions to support these women.

OBJECTIVE

To determine the effect of decision aid on anxiety and satisfaction with decisions (SWD) regarding the type of follow-up method after receiving an abnormal Papanicolaou smear result.

METHODS

This interventional study was conducted on women referred to the oncology clinic in Tabriz, Iran. Women were assigned to the intervention (n = 27) and control groups (n = 27) in a ratio of 1:1 using blocked randomization. The intervention group received a decision aid booklet. Participants in both groups completed questionnaires assessing demographic and obstetric characteristics, anxiety, SWD, and shared decision-making before and after the intervention.

RESULTS

The mean score for SWD in the intervention group was significantly higher than that in the control group after the intervention (median, 6.43 with 95% confidence interval of 3.11-7.76; P = .03). There was no significant difference between groups in the mean score of anxiety after intervention (median, 1.14; 95% confidence interval, -0.5 to 2.70; P = .19).

CONCLUSION

A decision aid can increase SWD among women with abnormal results in their cervical cancer screening.

IMPLICATIONS FOR PRACTICE

It is recommended that healthcare providers use decision aid tools to support and guide patients.

Iranian mother's perspectives about aspects and determinants of disrespect and abuse during labor and delivery: a qualitative study

Respectful maternity care (RMC) is a crucial strategy in improving postpartum experiences of mothers. This study aimed to explain women's perception of determining aspects and determinants of disrespect and abuse (D&A) during childbirth. This study was carried out from October 2019 to February 2020 in Tabriz-Iran. A total of 12 postpartum women were enrolled in this qualitative study by purposive sampling. The data were collected through in-depth semi structured interviews and simultaneously analyzed with a conventional content analysis approach. Thirty eight sub-themes and 11 main themes extracted from data analysis. The main themes included: "physical abuse," "psychological violence," "discrimination," "violation of privacy," "unmet needs and preferences," "nonparticipation in decision-making," "abandonment of women," "Lack of sympathy," "shortage of human and non-human resources," "unpleasant psychological atmosphere of the ward" and "facilitators of D&A." The results of our study indicated the importance of sympathy with mothers and professional ethics. Moreover, healthcare providers, administrators, and policy-makers should design patient-centered interventions in order to secure the material, psychological, and legal needs of women to receive respectful maternity care.

Woman-centered care and associated factors among midwives working in urban health centers and public and private hospitals in Tabriz, Iran: a cross-sectional study

BACKGROUND

Woman-centered care (WCC) is the cornerstone of the midwifery profession. However, no study has been conducted on WCC provided by Iranian midwives and its associated factors. Thus, this study aimed to determine WCC and factors associated with midwives' WCC for midwives working in urban health centers and public and private hospitals in Tabriz, Iran.

METHODS

This cross-sectional study was the first part (i.e., the quantitative phase) of a sequential explanatory mixed-method study conducted on 575 midwives working in urban health centers and public and private hospitals in Tabriz-Iran from November 2022 to January 2023. The required data was collected by distributing a socio-demographic and job characteristics questionnaire and woman-centered care scale-midwife self-report (WCCS-MSR). To determine the factors associated with WCC, an independent t-test or one-way analysis of variance (ANOVA) was used in bivariate analysis, and a general linear model (GLM) was employed in multivariate analysis to control possible confounding variables.

RESULTS

The statistical population consisted of 575 midwives, with a response rate of 88.2%. According to the GLM, the total mean WCCS-MSR score of single [β (95% CI) 23.02 (7.94 to 38.10)] and married [β (95% CI) 21.28 (6.83 to 35.72)] midwives was significantly higher than that of divorced midwives after adjusting their demographic and job characteristics. Also, the total mean WCCS-MSR score of midwives with sufficient income was significantly higher than those with insufficient income [β (95% CI) 8.94 (0.12 to 17.77). In addition, the total mean WCCS-MSR score of midwives with < 5 years of work experience [β (95% CI) - 7.87 (- 14.79 to - 0.94)], and midwives with official-experimental employment status [β (95% CI) - 17.99 (- 30.95 to - 5.02)], was significantly lower than those with more than 5 years of work experience and contractual employment status.

CONCLUSIONS

The findings indicate that marital status, level of income, years of practice, and employment status were significantly related to WCC provided by midwives. Focusing only on the midwifery community is insufficient to ensure the improved quality of WCC. However, arrangements should be made at three levels, including policy-makers, managers, and health care provider (midwives).

Evaluation of woman-centred care status by Iranian midwives and providing strategies to improve women-centred care: A sequential explanatory mixed method study protocol

AIM

The present study aimed to evaluate the status of WCC provided by Iranian midwives.

DESIGN

A sequential explanatory mixed method study protocol.

METHODS

The present study was conducted in three phases: quantitative, qualitative and mixed. The first phase is a cross-sectional study that will be performed on midwives working in health centres, public and private hospitals in Iranian. The second phase is a qualitative study, in which purposeful sampling will be used, meaning that the midwives who are part of the extreme cases according to the results of quantitative phase and are willing and able to express their own experiences regarding WCC will be selected. Also, pregnant and parturient women under their cover will also be interviewed. Finally, in the mixed phase, we will use a combination of two quantitative and qualitative studies, a literature review and expert opinion using a Delphi method to provide strategies to improve and promote WCC in midwives.

RESULTS

Achieving this goal is expected to provide positive outcomes such as strengthening the midwives professional relationship with women and reducing health care costs. No Patient or Public Contribution.

Consequences of Concurrent Myomectomy and Caesarean Section versus Caesarean Section Alone in the Last Two Decades: Systematic Review and Meta-analysis

Background:

Performing myomectomy concurrently with a caesarean section has been controversial for many decades.

Objective:

The present study mainly aims to evaluate the consequences of concurrent myomectomy and caesarean section versus caesarean section alone.

Methods:

In this systematic review, we have followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Electronic resources, such as MEDLINE, Cochrane, EMBASE, Scopus, and PubMed, were searched. A total of 3057 articles were reviewed. Of these, 33 met the inclusion criteria and were included in the final analysis. The reviewed outcomes were hemoglobin (Hb) before and after the operation, blood transfusion rate, hemorrhage, operation time, duration of hospitalization, and complications, such as fever.

Results:

A meta-analysis of 33 articles with 5586 participants in the caesarean myomectomy (CM) group and 2935 participants in the caesarean section (CS) group showed a statistically significant Hb decrease in the CM group [MD = 0.26, CI=95%(-0.33 to -0.19)]. The transfusion rate was higher in the CM group [OR=0.39(0.42-0.67)], and intraoperative hemorrhage was higher in the CM group [OR=0.56 (0.45 - 0.75) CI=95%]. The mean operation time [MD=1.17(1.10 -1.24) CI=95] and hospitalization time [MD=0.41 (0.34-0.48) CI=95%] were significantly higher in the CM group. There was no significant difference in the incidence of fever between the two groups [MD =1.06, CI=95%, p=0.923(0.78-1.43)].

Conclusion:

Concurrent CM is associated with a reduction in mean Hb and an increase in operation time and hospitalization time; however, it prevents additional surgery and costs; it is worthwhile to perform myomectomy at the time of caesarean section, especially by experienced surgeons with necessary preparations.

The global burden of cancer attributable to risk factors, 2010-19: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally.

METHODS

The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented.

FINDINGS

Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01-4·94) deaths and 105 million (95·0-116) DALYs for both sexes combined, representing 44·4% (41·3-48·4) of all cancer deaths and 42·0% (39·1-45·6) of all DALYs. There were 2·88 million (2·60-3·18) risk-attributable cancer deaths in males (50·6% [47·8-54·1] of all male cancer deaths) and 1·58 million (1·36-1·84) risk-attributable cancer deaths in females (36·3% [32·5-41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6-28·4) and DALYs by 16·8% (8·8-25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9-42·8] and 33·3% [25·8-42·0]).

INTERPRETATION

The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Designing a respectful maternity care guideline: a multiphase study

Background

There is no comprehensive guideline for respectful maternity care (RMC) promotion in Iran. This study aimed to design a RMC guideline based on a multiphase study.

Methods

In this multiphase mixed-methods study, recommendations were made for RMC promotion through the data obtained from Phase I (i.e., the quantitative section with a cross-sectional design), Phase II (i.e., the qualitative section with a content analysis method), and Phase III (i.e., focus group discussions with birth attendants as well as opinions of the specialized panel through the Delphi technique). The composed recommendations were then analyzed and finalized by relevant specialists in terms of execution capacity, approvability, and cost-effectiveness within the current context of Iran. Eventually, the resultant guideline were evaluated and approved by two members of the research team specializing in the research area in accordance with the Appraisal of Guideline for Research and Evaluation (AGREE).

Results

The results of this multiphase study led to 80 recommendations for RMC promotion. The recommendations were classified as eight areas called recommendations for the pregnancy period, recommendations for the labor period and delivery, recommendations for the neonatal period, occupational recommendations, supervision recommendations, national policy recommendations, recommendations for training students and staff, and general public recommendations.

Discussion

Based on the outcomes of disrespect and abuse, it is recommended to provide comprehensive guideline for policymakers and planners to formulate plans through the RMC promotion approach. Healthcare service policymakers can use this guideline to design some interventions to meet women’s financial, psychological, and legal needs.

Disrespect and abuse in the delivery room is associated with negative experience of delivery and poor maternal care quality index. Also, disrespect and abuse is the main barrier to achieving maternal health outcomes. In spite of the considerable achievements in maternal and child health, there is still a large number of maternal and neonatal mortality worldwide. It seems that disrespect and abuse is a key potential obstacle hindering access to delivery facilities and skilled care providers. To achieve the sustainable development 2030 goals developed by the World Health Organization (WHO) (Goal 3.1: Ensure health lives and promote well-being for all at all ages: reduce the global maternal mortality ratio to less than 70 per 100,1000 live birth), stakeholders and relevant institutions should consider respectful pregnancy and delivery care services as a key solution to reducing maternal mortality. Nevertheless, there is no comprehensive guideline with regards to respectful maternity care in the WHO or provided by other countries. In this multiphase mixed-methods study, recommendations were made for respectful maternity care promotion through the data obtained from Phase I (i.e., the quantitative section with a cross-sectional design), Phase II (i.e., the qualitative section with a content analysis method), and Phase III (i.e., focus group discussions with birth attendants as well as opinions of the specialized panel through the Delphi technique). The composed recommendations were then analyzed and finalized by relevant specialists in terms of execution capacity, approvability, and cost-effectiveness within the current context of Iran. The results of this multiphase study led to 80 recommendations for RMC promotion. The recommendations were classified as eight areas called recommendations for the pregnancy period, recommendations for the labor period and delivery, recommendations for the neonatal period, occupational recommendations, supervision recommendations, national policy recommendations, recommendations for training students and staff, and general public recommendations.

Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life Years for 29 Cancer Groups From 2010 to 2019: A Systematic Analysis for the Global Burden of Disease Study 2019

IMPORTANCE

The Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) provided systematic estimates of incidence, morbidity, and mortality to inform local and international efforts toward reducing cancer burden.

OBJECTIVE

To estimate cancer burden and trends globally for 204 countries and territories and by Sociodemographic Index (SDI) quintiles from 2010 to 2019.

EVIDENCE REVIEW

The GBD 2019 estimation methods were used to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) in 2019 and over the past decade. Estimates are also provided by quintiles of the SDI, a composite measure of educational attainment, income per capita, and total fertility rate for those younger than 25 years. Estimates include 95% uncertainty intervals (UIs).

FINDINGS

In 2019, there were an estimated 23.6 million (95% UI, 22.2-24.9 million) new cancer cases (17.2 million when excluding nonmelanoma skin cancer) and 10.0 million (95% UI, 9.36-10.6 million) cancer deaths globally, with an estimated 250 million (235-264 million) DALYs due to cancer. Since 2010, these represented a 26.3% (95% UI, 20.3%-32.3%) increase in new cases, a 20.9% (95% UI, 14.2%-27.6%) increase in deaths, and a 16.0% (95% UI, 9.3%-22.8%) increase in DALYs. Among 22 groups of diseases and injuries in the GBD 2019 study, cancer was second only to cardiovascular diseases for the number of deaths, years of life lost, and DALYs globally in 2019. Cancer burden differed across SDI quintiles. The proportion of years lived with disability that contributed to DALYs increased with SDI, ranging from 1.4% (1.1%-1.8%) in the low SDI quintile to 5.7% (4.2%-7.1%) in the high SDI quintile. While the high SDI quintile had the highest number of new cases in 2019, the middle SDI quintile had the highest number of cancer deaths and DALYs. From 2010 to 2019, the largest percentage increase in the numbers of cases and deaths occurred in the low and low-middle SDI quintiles.

CONCLUSIONS AND RELEVANCE

The results of this systematic analysis suggest that the global burden of cancer is substantial and growing, with burden differing by SDI. These results provide comprehensive and comparable estimates that can potentially inform efforts toward equitable cancer control around the world.

Global, regional, and national progress towards Sustainable Development Goal 3.2 for neonatal and child health: all-cause and cause-specific mortality findings from the Global Burden of Disease Study 2019

BACKGROUND

Sustainable Development Goal 3.2 has targeted elimination of preventable child mortality, reduction of neonatal death to less than 12 per 1000 livebirths, and reduction of death of children younger than 5 years to less than 25 per 1000 livebirths, for each country by 2030. To understand current rates, recent trends, and potential trajectories of child mortality for the next decade, we present the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 findings for all-cause mortality and cause-specific mortality in children younger than 5 years of age, with multiple scenarios for child mortality in 2030 that include the consideration of potential effects of COVID-19, and a novel framework for quantifying optimal child survival.

METHODS

We completed all-cause mortality and cause-specific mortality analyses from 204 countries and territories for detailed age groups separately, with aggregated mortality probabilities per 1000 livebirths computed for neonatal mortality rate (NMR) and under-5 mortality rate (U5MR). Scenarios for 2030 represent different potential trajectories, notably including potential effects of the COVID-19 pandemic and the potential impact of improvements preferentially targeting neonatal survival. Optimal child survival metrics were developed by age, sex, and cause of death across all GBD location-years. The first metric is a global optimum and is based on the lowest observed mortality, and the second is a survival potential frontier that is based on stochastic frontier analysis of observed mortality and Healthcare Access and Quality Index.

FINDINGS

Global U5MR decreased from 71·2 deaths per 1000 livebirths (95% uncertainty interval [UI] 68·3-74·0) in 2000 to 37·1 (33·2-41·7) in 2019 while global NMR correspondingly declined more slowly from 28·0 deaths per 1000 live births (26·8-29·5) in 2000 to 17·9 (16·3-19·8) in 2019. In 2019, 136 (67%) of 204 countries had a U5MR at or below the SDG 3.2 threshold and 133 (65%) had an NMR at or below the SDG 3.2 threshold, and the reference scenario suggests that by 2030, 154 (75%) of all countries could meet the U5MR targets, and 139 (68%) could meet the NMR targets. Deaths of children younger than 5 years totalled 9·65 million (95% UI 9·05-10·30) in 2000 and 5·05 million (4·27-6·02) in 2019, with the neonatal fraction of these deaths increasing from 39% (3·76 million [95% UI 3·53-4·02]) in 2000 to 48% (2·42 million; 2·06-2·86) in 2019. NMR and U5MR were generally higher in males than in females, although there was no statistically significant difference at the global level. Neonatal disorders remained the leading cause of death in children younger than 5 years in 2019, followed by lower respiratory infections, diarrhoeal diseases, congenital birth defects, and malaria. The global optimum analysis suggests NMR could be reduced to as low as 0·80 (95% UI 0·71-0·86) deaths per 1000 livebirths and U5MR to 1·44 (95% UI 1·27-1·58) deaths per 1000 livebirths, and in 2019, there were as many as 1·87 million (95% UI 1·35-2·58; 37% [95% UI 32-43]) of 5·05 million more deaths of children younger than 5 years than the survival potential frontier.

INTERPRETATION

Global child mortality declined by almost half between 2000 and 2019, but progress remains slower in neonates and 65 (32%) of 204 countries, mostly in sub-Saharan Africa and south Asia, are not on track to meet either SDG 3.2 target by 2030. Focused improvements in perinatal and newborn care, continued and expanded delivery of essential interventions such as vaccination and infection prevention, an enhanced focus on equity, continued focus on poverty reduction and education, and investment in strengthening health systems across the development spectrum have the potential to substantially improve U5MR. Given the widespread effects of COVID-19, considerable effort will be required to maintain and accelerate progress.

Characteristics, clinical and laboratory data and outcomes of pregnant women with confirmed SARS-CoV-2 infection admitted to Al-Zahra tertiary referral maternity center in Iran: a case series of 24 patients

BACKGROUND

Physiological changes during pregnancy put pregnant women at higher risk for COVID-19 complications. The objective of this study was to evaluate clinical and laboratory characteristics and outcomes of 24 COVID-19 pregnant patients and their newborns referred to the Al-Zahra tertiary maternity hospital in Tabriz, Iran.

METHODS

Clinical records of 24 COVID-19 confirmed pregnant patients were retrospectively reviewed from10 March 2020 to 15 April 2020. Vertical transition was assessed through neonatal pharyngeal swab samples. The study has been approved by the Tabriz University Medical Ethics Committee (IR.TBZMED.REC.1399.497).

RESULTS

There were 24 hospitalized cases with clinical symptoms and confirmed diagnosis of COVID-19. The mean age of cases was 26.5 years; most were nulliparous (54.2%), in their third trimester (62.5%) and were in the type A blood group. Clinical symptoms in order of prevalence were cough, fever, dyspnea, myalgia, anosmia, and diarrhea. Oxygen saturation (SpO2) in 70.8% cases was in the normal range (greater than 93%). The risk of premature labor or abortion in cases showed no increase. 12 cases were in ongoing normal status; on follow up, 11 cases had delivered their babies at term and one had ended in IUFD because of pregnancy-induced hypertension. All delivered babies were healthy. Caesarean section in all cases was performed under obstetric indications or maternal demand, and no relation was found between COVID-19 and Caesarean delivery. Neonatal outcomes according to gestational age in 8 cases out of 11 (72.72%) were desirable; neonatal morbidity and mortality resulted from pregnancy complications. Blood pH in 6 neonates was assessed due to immaturity and NICU admission, all of which were in normal ranges except one case related to HELLP syndrome. There was no evidence of vertical transmission.

CONCLUSIONS

Findings suggest that clinical symptoms in pregnancy were similar to non-pregnant women, no rise in risk of premature labor or abortion was seen, and vertical transmission was not observed in none of cases. Lymphopenia was the leading laboratory change. Given asymptomatic cases despite severe forms of infection in pregnancies, we propose screening in all suspected cases. All placentas and newborns should be tested in the field for vertical transmission.

Changes of body composition and circulating neopterin, omentin-1, and chemerin in response to thylakoid-rich spinach extract with a hypocaloric diet in obese women with polycystic ovary syndrome: A randomized controlled trial

This trial evaluated the effects of thylakoid-rich spinach extract supplementation combined with a hypocaloric diet on body composition and serum levels of neopterin, chemerin, and omentin-1 in obese women with polycystic ovary syndrome (PCOS). In this randomized controlled trial, 48 obese women with PCOS, aged 20-45 years old, were recruited and randomly divided into thylakoid (n = 24) and placebo (n = 24) groups. They received a low-calorie diet with 5 g/day thylakoid-rich spinach extract or a low-calorie diet with 5 g/day placebo for 12 weeks. The mean age of the participants of the thylakoid group was 31.86 years, and the placebo group was 32.04 years. Thylakoid-rich spinach extract supplementation with a low-calorie diet increased serum levels of omentin-1 (10.90 vs. 3.87 ng/L; p < .001) and decreased fat mass (-5.19 vs. -1.35 kg; p < .001) and serum levels of neopterin (-0.66 vs. -0.38 nmol/L; p = .003) and chemerin (-41.24 vs. -11.26 ng/L; p < .001) in the thylakoid group compared to the placebo group. A significant improvement in omentin-1, chemerin, and neopterin by thylakoid-rich spinach extract supplementation was under the influence of weight change and insulin resistance status throughout the study. A significant decrease in the other anthropometric indices and insulin resistance was also observed in the thylakoid group, compared to the placebo group (p < .001, for all parameters). Thylakoid-rich spinach extract combined with a low-calorie diet increased circulating omentin-1 and decreased fat mass, abdominal obesity, as well as circulating chemerin, neopterin, and insulin in obese women with PCOS.

The psychometric properties of the respectful maternity care (RMC) for an Iranian population

BACKGROUND

The absence of Respectful Maternity Care (RMC) deters mothers from seeking maternity care services. Given the importance of RMC and the lack of a standard tool for its assessment in Iran, the present study was conducted to translate and assess the psychometric properties of the RMC questionnaire in Iranian women.

METHODS

Forward-backward method was used for translating the questionnaire from English into Persian. A total of 265 postpartum women entered the study by simple random sampling from public and private hospitals in Tabriz, Iran. The validity of the questionnaire was confirmed through the face, content and construct validity. Construct validity was assessed through exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were used to confirm the reliability of the questionnaire. Internal consistency was examined by measuring the Cronbach's alpha in a sample of 20 mothers, and test-retest stability by calculating the Intraclass Correlation Coefficient (ICC) in the same group of mothers, who had completed the questionnaire twice with a two-week interval.

RESULTS

The exploratory factor analysis led to the extraction of one factor. Item 12 was eliminated due to its low factor loading. X2/df was less than 5, and RMSEA was less than 0.08, which confirms the validity of this model. The Cronbach's alpha coefficient was obtained as 0.93 and ICC (with 95% confidence interval) as 0.98 (0.96 to 0.99).

CONCLUSION

The results of the study demonstrated that the Iranian RMC scale can be used as a valid and reliable instrument to assess RMC in Iran.

Respectful maternity care and its relationship with childbirth experience in Iranian women: a prospective cohort study

Background

Intrapartum respectful maternity care is defined as a fundamental human right that can affect the mother’s experiences. This study aimed to determine the status of respectful maternity care and its relationship with childbirth experience among Iranian women.

Methods

This prospective cohort study recruited 334 postpartum women in postpartum wards of two public and four private hospitals in Tabriz, Iran. Quota sampling was used based on the number of births in each hospital. Data were collected through interviews with the use of the following tools: sociodemographic and obstetrics characteristics questionnaire, respectful maternity care scale (6 to 18 h postpartum), and childbirth experience questionnaire (30 to 45 days postpartum). The General Linear Model was used to determine the relationship between respectful maternity care and childbirth experience.

Results

The mean respectful maternity care score was 62.58 with a range of 15 to 75, and the total childbirth experience score was 3.29 with a range of 1 to 4. After adjusting for sociodemographic and obstetrics characteristics, a statistically significant direct correlation was found between respectful maternity care and a positive childbirth experience (P < 0.001).

Conclusions

The findings reveals a direct relationship between respectful maternity care and positive childbirth experience. Therefore, it is recommended that mangers and policy makers in childbirth facilities reinforce facilitating a respectful maternity care to improve women’s child birth experience and prevent potential adverse effects of negative childbirth experiences.

Prevalence and predictors of perceived disrespectful maternity care in postpartum Iranian women: a cross-sectional study

Background

Disrespectful maternity care is a key impediment to achieving a good quality care. Identifying predicting factors can be used in mitigating any potential risk in for disrespect and abuse in maternity care. The present study was conducted to determine prevalence and predictors of perceived disrespectful maternity care among Iranian women.

Methods

A cross-sectional study was conducted in three public and three private hospitals in the city of Tabriz involving 334 postpartum women. Tools included socio-demographic, pregnancy, labour and birth characteristics questionnaires, and disrespect and abuse scales. Data were collected in 6 to 18 h after birth. Multivariate logistic regression was used to determine predictors of disrespectful maternity care.

Results

A majority of the women (253; 75.7%) reported one or several types of perceived disrespectful maternity care. The most frequent types related to not allowing women to choose labour positions (142; 44.3%) and not allowing them to move during labour (148; 42.5%). Nighttime childbirth (aOR 3.07; 95% CI 1.61 to 5.88) increased the likelihood of perceived disrespectful maternity care. However, presence of spouses to accompany their wives in waiting rooms (aOR 0.32; 95% CI 0.11 to 0.88), the attendance of private physicians (aOR 0.05; 95% CI 0.02 to 0.12), and midwives (aOR 0.22; 95% CI 0.11 to 0.45) decreased the likelihood of perceived disrespectful maternity care.

Conclusion

The results showed high levels of perceived disrespectful maternity care in postpartum women. Therefore, appropriate interventions, such as encouraging spouses’ presence, increasing the number of night shift staff, and training obstetric residents and midwives by holding ethics classes, with particular emphasis on empathy with patients.

The effects of spinach-derived thylakoid supplementation in combination with calorie restriction on anthropometric parameters and metabolic profiles in obese women with polycystic ovary syndrome: a randomized, double-blind, placebo-controlled clinical trial

BACKGROUND

There is a promising outlook regarding the potential effect of spinach-derived thylakoids in the management of obesity and its associated metabolic disturbances. This research aimed to evaluate the effects of spinach-derived thylakoids supplementation combined with a calorie-restricted diet on anthropometric and metabolic profiles in obese women with the polycystic ovary syndrome (PCOS).

METHODS

In a 12-week double-blind placebo-controlled randomized clinical trial, 48 females with obesity and PCOS were randomly allocated into either intervention (5 g/day thylakoid) or placebo (5 g/day cornstarch) groups along with calorie-restricted diets. Anthropometric measures, physical activity levels, dietary intakes, insulin resistance markers, as well as serum levels of insulin, fasting blood glucose (FBG), non-esterified fatty acids (NEFA), and sex hormones including dehydroepiandrosterone sulfate (DHEAS), follicle-stimulating hormone (FSH), luteinizing hormone (LH), sex hormone-binding globulin (SHBG), and free androgen index (FAI) were evaluated pre-and post-intervention.

RESULTS

After the 12-week intervention, there were significant decreases in weight (- 6.97 ± 0.52 vs. -3.19 ± 0.72 kg; P < 0.001), waist circumference (- 7.78 ± 2.50 vs. -3.73 ± 1.40 cm; P < 0.001), fat mass (- 5.19 ± 0.53 vs. -1.36 ± 0.39 kg; P < 0.001), and insulin levels (- 5.40 ± 1.86 vs. -1.19 ± 0.85 μU/mL; P < 0.001) in the spinach-derived thylakoid group compared to the placebo group. Furthermore, insulin resistance markers and serum levels of testosterone decreased significantly in the thylakoid group compared to the placebo group (P < 0.05). The changes in other parameters did not show significant differences between the two groups.

CONCLUSIONS

Spinach-derived thylakoid supplementation resulted in more favorable improvements in anthropometric indices and insulin sensitivity compared to the calorie restriction alone.

TRIAL REGISTRATION

The study was approved by the Ethics Committee of Research Vice-chancellor of Tabriz University of Medical Sciences, Tabriz, Iran, and was registered in the Iranian Registry of Clinical Trials (registration ID: IRCT20140907019082N9 ).

Quercetin and polycystic ovary syndrome, current evidence and future directions: a systematic review

Polycystic ovary syndrome (PCOS) is a polygenic endocrine disorder and the most common gynecological endocrinopathy among reproductive-aged women. Current remedies are often used only to control its signs and symptoms, while they are not thoroughly able to prevent complications. Quercetin is an herbal bioactive flavonoid commonly used for the treatment of metabolic and inflammatory disorders. Thus, this systematic review was conducted to evaluate the efficacy of quercetin supplementation in subjects with PCOS. Databases until March 2019 were searched. All human clinical trials and animal models evaluating the effects of quercetin on PCOS women were included. Out of 253 articles identified in our search, 8 eligible articles (5 animal studies and 3 clinical trials) were reviewed. The majority of studies supported the beneficial effects of quercetin on the ovarian histomorphology, folliculogenesis, and luteinisation processes. The effects of quercetin on reducing the levels of testosterone, luteinizing hormone (LH), and insulin resistance were also reported. Although quercetin improved dyslipidemia, no significant effect was reported for weight loss. It is suggested that the benefits of quercetin may be more closely related to antioxidant and anti-inflammatory features of quercetin rather than weight-reducing effects. Therefore, this review article provides evidence that quercetin could be considered as a potential agent to attenuate PCOS complications. However, due to the paucity of high-quality clinical trials, further studies are needed.

Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2017: A Systematic Analysis for the Global Burden of Disease Study

Importance

Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.

Objective

To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning.

Evidence Review

We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence.

Findings

In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs).

Conclusions and Relevance

The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

The prognostic role of preoperative serum CA125 levels in patients with advanced endometrial carcinoma

BACKGROUND

Lifetime risk of developing endometrial cancer is 2.17%. There is controversy regarding the predictive value of Cancer Antigen 125 (CA125) in endometrial cancer as well as the significance of its relationship with prognostic factors and appropriate cut-off value.

OBJECTIVE

The aim of the present study was to investigate the prognostic role of CA125 in advanced endometrial carcinoma and determination of the appropriate cut-off value.

METHODS

A sample of 91 patients was retrospectively selected from a population of 501 patients suffering from endometrial cancer during 1995 to 2015 in accordance with the inclusion criteria. The relation between clinicopathological variables and CA125 were analyzed. In order to determine sensitivity and specificity of various cut-off levels, receiver operating characteristic (ROC) curve analysis was performed for associated factors confirmed by logistic regression analysis.

RESULTS

In 35% of patients, CA125 values were 35 u/ml, and in 52%, the values were equal to or greater than 20 u/ml. High preoperative CA125 was significantly related with advanced stage, ovarian involvement, omental metastasis, and myometrial invasion equal to or greater than 50%. According to the ROC curve, the suitable cut-off value for CA125 in advanced stage (sensitivity = 73%, specificity = 55%, positive predictive value = 18%, negative predictive value = 78%) and myometrial invasion equal to or greater than 50% (sensitivity = 64%, specificity = 61%, positive predictive value = 47%, negative predictive value = 74%) was 20 u/ml. Further, the suitable cut-off value for CA125 in involvement of the ovaries (sensitivity = 77%, specificity = 72%, positive predictive value = 31%, negative predictive value = 95%) and omental involvement (sensitivity = 70%, specificity = 70%, positive predictive value = 22%, negative predictive value = 95%) was 35 u/ml.

CONCLUSIONS

In endometrial carcinoma, due to the relationship of CA125 with numerous prognostic factors, it is recommended that CA125 measurement be included in preoperative evaluation. In case of high CA125 levels, complete surgical staging including lymphadenectomy and omentectomy should be considered.

Expression analysis of microRNA-125 in patients with polycythemia vera and essential thrombocythemia and correlation with JAK2 allele burden and laboratory findings

INTRODUCTION

The JAK2V617F mutation has emerged in recent years as a diagnostic as well as a treatment target in patients with polycythemia vera (PV) and essential thrombocythemia (ET). The disease phenotype is also influenced by other factors such as microRNA (miRNA) deregulation. The aim of this study was to investigate miR-125 expression level in these patients with those obtained from healthy control subjects and its correlation with JAK2 allele burden and laboratory findings.

METHODS

In total, forty patients with a clinical diagnosis of PV and ET were examined at the time of diagnosis. Ten healthy subjects were checked as controls. We performed JAK2 V617F allele burdens measurement and expression analysis of miR-125b-5p, miR-125b-3p, miR-125a-5p, and miR-125a-3p in leukocytes isolated from peripheral blood by quantitative real-time polymerase chain reaction.

RESULTS

MiR-125b-5p and miR-125a-5p were upregulated in both patients with PV (P = 0.00 and P = 0.003, respectively) and ET (P = 0.02 and P = 0.002, respectively). In PV group, a significant correlation was observed between miR-125a-5p and platelet counts (P = 0.01, r = 0.531). The correlation between miRNA and JAk2 allele burden was not significant.

CONCLUSION

In conclusion, our data indicate that other factors such as aberrant miR-125 expression may influence on the disease phenotype in patients with PV and ET.

Association between Thrombophilia and Repeated Assisted Reproductive Technology Failures

PURPOSE

This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART) failures.

METHODS

The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 with three or more previously failed ARTs (A) and control group consisted of 36 patients with successful pregnancy following ARTs (B). All patients were tested for the presence of mutated thrombophilic genes including factor V Leiden (FVL), Methylenetetrahydrofolate reductase (MTHFR) and Prothrombin (G20210A) using real-time polymerase chain reaction (RT- PCR).

RESULTS

Mutation of FVL gene was detected in 5.9% women of group A (2 of 34) compared with 2.8% women (1 of 36) of control group (P = 0.6). Mutation of MTHFR gene was found in 35.3% (12 cases) as compared with 50% (18 cases) of control (35.3% versus 50%; P = 0.23). Regarding Prothrombin, only control group had 5.6% mutation (P = 0.49). No significant differences were detected in the incidences of FVL, Prothrombin and MTHFR in the study group A compared with the control group B.

CONCLUSION

The obtained results suggest that thrombophilia does not have a significant effect in ART failures.

Clinical trial design in adult reflux disease: a methodological workshop

BACKGROUND

The development of well-tolerated acid suppressant drugs has stimulated substantial growth in the number of trials assessing therapy options for gastro-oesophageal reflux disease (GERD).

AIM

To develop consensus statements to inform clinical trial design in adult patients with GERD.

METHODS

Draft statements were developed employing a systematic literature review. A modified Delphi process including three rounds of voting was used to reach consensus. Between voting, statements were revised based on feedback from the Working Group and additional literature reviews. The final vote was at a face-to-face meeting that included discussion time. Voting was conducted using a six-point scale.

RESULTS

At the last vote, 93% of the final 102 statements achieved consensus (defined a priori as being supported by >or=75% of the votes). The Working Group strongly supported the development of validated patient-reported outcome instruments. Symptom assessments carried out by the investigator were considered unacceptable. There was agreement that exclusion from clinical trials should be minimized to improve generalizability, that prospective evaluation ideally requires electronic timed/dated methods and that endoscopists should be blinded to patient symptom status.

CONCLUSIONS

Implementation of the consensus statements will improve the quality and comparability of trials, and make them compatible with regulatory requirements.
