Prevalence and correlates of diagnosed and probable polycystic ovary syndrome (PCOS) in a cohort of parous women.

OBJECTIVES: To assess correlates of diagnosed and probable polycystic ovary syndrome (PCOS) among parous women. METHODS: This study includes 557 women recruited from multi-specialty clinics in eastern Massachusetts. We categorized women as "diagnosed PCOS" based on medical records and self-reported clinician-diagnoses. Next, we constructed a category of "probable PCOS" for women without a diagnosis but with ≥2 of the following: ovulatory dysfunction (cycle length<21 or ≥35 days), hyperandrogenism (free testosterone>75th percentile), or elevated anti-Müllerian hormone (>75th percentile). We classified the remaining as "no PCOS," and compared characteristics across groups. RESULTS: 9.7% had diagnosed and 9.2% had probable PCOS. The frequency of irregular cycles was similar for diagnosed and probable PCOS. Free testosterone and AMH were higher for probable than diagnosed PCOS. Frequency of irregular cycles and both hormones were higher for the two PCOS groups vs. the no PCOS group. Obesity prevalence for diagnosed PCOS was twice that of probable PCOS (43.9% vs. 19.6%), yet the two groups had similar HbA1c and adiponectin. CONCLUSIONS: Women with probable PCOS are leaner but have comparable glycemic traits to those with a formal diagnosis, highlighting the importance of assessing biochemical profiles among women with irregular cycles, even in the absence of overweight/obesity.

Consumption of pistachio nuts positively affects lipid profiles: A systematic review and meta-analysis of randomized controlled trials.

We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effects of consuming pistachio nuts on lipid profiles (total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglyceride [TG]). Databases of PubMed, Scopus, ISI Web of Science, and Cochrane Library were searched from inception to June 2019 to identify RCTs documenting the effects of consuming pistachio nuts on blood lipid profiles in adults. Effect sizes were reported as weighted mean difference (WMD) and 95% confidence interval (CI) using the random-effects models (DerSimonian-Laird method). Twelve eligible RCTs were included. Consumption of pistachio nuts decreased TC (WMD: -7.48 mg/dL; 95% CI, -12.62 to -2.34), LDL-C (WMD: -3.82 mg/dL; 95% CI, -5.49 to -2.16) and TG (WMD: -11.19 mg/dL; 95% CI, -14.21 to -8.17) levels. However, HDL-cholesterol levels (WMD: 2.45 mg/dL; 95% CI, -2.44 to 7.33) did not change following pistachio consumption. Consuming pistachio nuts may improve lipid profiles (TC, LDL-C, TG) in adults and may be protective against cardiometabolic diseases. However, further studies with larger sample sizes are required to confirm these results.

Effects of pistachios on glycaemic control: a systematic review and meta-analysis of randomised controlled trials.

To evaluate the effects of pistachio consumption on the glucoregulatory status in individuals with a high risk of CVD, a systematic review and meta-analysis of randomised controlled trials (RCT) were conducted. Online databases including PubMed, Scopus, Web of Science and Cochrane Library were searched from inception until June 2019. Human trials that reported data for fasting blood sugar (FBS), fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) were included. Data were pooled using the random effect models and expressed as weighted mean difference (WMD) with 95 % CI. Eight RCTs were included in the analyses. Pistachio consumption, exchanged isocalorically for other foods, decreased FBS (WMD: -5·32 mg/dl, 95 % CI (-7·80, -2·64), P < 0·001) and insulin (WMD: -1·86 µIU/ml, 95 % CI (-3·13, -0·59), P < 0·01) concentrations in individuals with a high risk of CVD. However, no changes were observed in the levels of HOMA-IR between the groups (WMD: -0·66, 95 % CI (-1·89, 0·58), P = 0·30). Pistachio consumption may improve glucoregulatory status in individuals at risk for CVD, as evidenced by reduced FBS and insulin concentrations. However, due to the limited availability of studies with diabetic cases and relatively small sample sizes of available studies, well-designed trials with adequate sample sizes aimed at diabetic populations are recommended.

Associations between diet quality and migraine headaches: a cross-sectional study.

AIMS: We evaluated associations between diet quality and migraine outcomes. METHODS: The current work represented a cross-sectional study on 262 patients with migraine (20-50 y). Diet quality was assessed using the standard healthy eating index 2015 (HEI-2015) and alternative healthy eating index 2010 (AHEI-2010). A validated 168-item food frequency questionnaire was used to assess dietary intake. Migraine outcomes included clinical factors (severity, duration, frequency, and disability related to migraine) and serum nitric oxide (NO). Associations between diet quality indices and migraine outcomes were evaluated using linear regressions, and ß and 95% corresponding confidence interval (CI) were reported. RESULTS: HEI-2015 was inversely associated with migraine frequency (ß = -4.75, 95% CI: -6.73, -2.76) in patients with the highest HEI scores (third tertile) vs. those with the lowest scores (first tertile) after adjusting for relevant confounders. AHEI-2010 was inversely associated with migraine frequency (ß = -3.67, 95% CI: -5.65, -1.69) and migraine-related disability (ß = -2.74, 95% CI: -4.79, -0.68) in adjusted models. Also, AHEI-2010 was inversely associated with migraine severity in patients in the second vs. first tertile (ß = -0.56; 95% CI: -1.08, -0.05). We detected no associations between diet quality and NO levels (All P > 0.14). CONCLUSIONS: Improved diet quality may be associated with favorable migraine outcomes (lower headache frequency, severity, and migraine-related disability). Future studies are required to confirm and delineate the causal mechanisms of our observations.

Comprehensive evaluation of disparities in cardiometabolic and reproductive risk between Hispanic and White women with polycystic ovary syndrome in the United States: a systematic review and meta-analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to comprehensively compare cardiometabolic and reproductive health risk between Hispanic and White women with polycystic ovary syndrome in the United States in response to the call by the international guideline for polycystic ovary syndrome to delineate health disparities. DATA SOURCES: Databases of MEDLINE, Web of Science, and Scopus were initially searched through October 25, 2020, and confirmed on February 1, 2021. STUDY ELIGIBILITY CRITERIA: Observational studies comparing glucoregulatory, lipid profile, anthropometric, blood pressure, androgen, ovarian morphology, oligoanovulation, and infertility status between Hispanic and White women with polycystic ovary syndrome were included. The primary outcome was metabolic syndrome risk. Furthermore, major cardiovascular events (stroke, coronary heart disease, and heart failure) and mortality rate (cardiovascular death and total mortality) data were evaluated. Studies on adolescents (<2 years after menarche), pregnant, or menopausal-aged women (>50 years) were excluded. METHODS: Data were pooled by random-effects models and expressed as mean differences and 95% confidence intervals. Risk of bias was assessed by the Newcastle-Ottawa Scale. RESULTS: A total of 11 studies (n=2267; 589 Hispanic and 1678 White women) were eligible. All studies, including both White and Hispanic women, had high-quality assessment (Newcastle-Ottawa Scale score of ≥8). Hispanic women exhibited comparable metabolic syndrome prevalence (7% [95% confidence interval, -1 to 14]; P=.06; I2=0%); however, Hispanic women exhibited higher modified Ferriman-Gallwey score (0.60 [95% confidence interval, -0.01 to 1.21]; P=.05; I2=0%), fasting insulin (5.48 µIU/mL [95% confidence interval, 3.11-7.85]; P≤.01; I2=40.0%), and homeostatic model assessment of insulin resistance (1.20 [95% confidence interval, 0.50-1.89]; P≤.01; I2=43.0%) than White women. The 2 groups had comparable glucose, lipid profile, waist circumference, blood pressure, and androgen status (all P≥.08). Findings about group differences in certain reproductive outcomes (ie, ovarian dysmorphology and infertility) were contradictory and described only narratively as inclusion in the meta-analyses was not possible. No study reported on cardiovascular events or mortality. CONCLUSION: Hispanic women with polycystic ovary syndrome exhibited greater impairments in glucoregulatory status than White women. Disparities in reproductive risks could not be concluded. The degree to which glucoregulatory aberrations translate into patient-pressing diseases (diabetes mellitus and infertility) remains a major roadblock given the paucity of available evidence. Our observations have supported the consideration of these disparities in the diagnostic, monitoring, and management practices for polycystic ovary syndrome and reinforced the need to elucidate mechanisms that account for the observed disparities to foster equity in polycystic ovary syndrome care.

Efficacy of synbiotic interventions on blood pressure: a systematic review and meta-analysis of clinical trials.

PURPOSE: The present systematic review and meta-analysis aimed to evaluate the effect of synbiotic interventions on blood pressure levels in adults. METHODS: A systematic literature search was conducted in the databases of MEDLINE, Scopus, Web of Science, and Cochrane through March 2020 to identify all randomized control trials (RCTs) investigating the effects of synbiotic interventions on blood pressure parameter, including systolic (SBP) and diastolic blood pressure (DBP). Grading of Recommendations Assessment, Development and Evaluation (GRADE) scale was used to assess the certainty of evaluated outcomes and determine the strength of recommendations. RESULTS: Eleven RCTs were included in the meta-analysis. Synbiotic interventions significantly reduced SBP (-3.02 mmHg; 95% CI: -4.84, -1.21; I2 = 55%) without changing DBP levels (-0.57 mmHg; 95% CI: -1.78, 0.64; I2 = 50%). Subgroup analyses revealed that the SBP-lowering effects of synbiotic interventions were more pronounced wherein trials were longer (≥12 weeks), synbiotic interventions were administrated as a supplement, and participants were younger (<50 years old). Also, a significant improvement in both SBP and DBP levels was evident in subgroups with a lower (<30 kg/m2) body mass index. CONCLUSIONS: Synbiotic interventions may significantly improve SBP levels in adults.

Effects of the Dietary Approaches to Stop Hypertension (DASH) diet on clinical, quality of life and mental health outcomes in women with migraine: a randomised controlled trial.

The relationship between the Dietary Approaches to Stop Hypertension (DASH) diet and clinical, quality of life and mental health outcomes in migraine is unknown. To address this knowledge gap, we conducted a parallel-group, randomised controlled trial to evaluate the effect of the DASH diet on these health outcomes in women with migraine. Of 102 eligible women (20-50 years), fifty one randomised to the DASH and fifty one to the usual dietary advice (control) groups completed a 12-week intervention. The DASH diet was designed using a 7-d menu cycle to provide 15-20 % of total daily energy requirements from proteins, 25-30 % from fats and 55-60 % from carbohydrates. Dietary records and serum vitamin C levels were used to assess women's compliance with the DASH diet. The clinical symptoms of migraine (i.e., frequency, duration and severity) and quality of life and mental health (i.e., depression, anxiety and stress) outcomes were assessed in groups pre-and post-intervention. We observed greater decreases in the frequency (-3·00 v. -1·40, P = 0·025) and severity (-1·76 v. -0·59, P < 0·001) of migraine in the DASH v. control group post-intervention. Similarly, the DASH group exhibited a tendency towards greater decreases in migraine duration (-0·58 v. -0·33 d, P = 0·053) and had lower scores of depression (-4·50 v. -2·73, P = 0·019) and stress (-5·84 v. -2·98, P = 0·011) v. controls. However, the quality of life and anxiety outcomes remained comparable in groups post-intervention. Together, evidence supports the benefits of the DASH diet on improving migraine health outcomes in reproductive-aged women. Further research is needed to confirm our findings.

Diagnostic accuracy of first and early second trimester multiple biomarkers for prediction of gestational diabetes mellitus: a multivariate longitudinal approach.

BACKGROUND: Gestational Diabetes Mellitus (GDM) is an underlying cause of maternal and newborn morbidity and mortality all around the world. Timely diagnosis of GDM plays an important role in reducing its adverse consequences and burden. This study aimed to determine diagnostic accuracy of multiple indicators in complete blood count (CBC) test for early prediction of GDM. METHODS: In this prospective cohort study, the data from 600 pregnant women was analyzed. In the study sample, the two-step approach was utilized for the diagnosis of GDM at 24-28 weeks of gestation. We also used the repeated measures of hemoglobin (Hb), hematocrit (Hct), fasting blood sugar (FBS) and red blood cell count (RBC) in the first and early second trimesters of pregnancy as the longitudinal multiple indicators for early diagnosis of GDM. The classification of pregnant women to GDM and non-GDM groups was performed using a statistical technique based on the random-effects modeling framework. RESULTS: Among the sample, 49 women (8.2%) were diagnosed with GDM. In the first and early second trimester of pregnancy, the mean HcT, Hb and FBS of women with GDM was significantly higher than non-GDMs (P < 0.001). The concurrent use of multiple longitudinal data from HcT, Hb, RBC and FBS in the first and early second trimester of pregnancy resulted in a sensitivity, specificity and area under the curve (AUC) of 87%, 70% and 83%, respectively, for early prediction of GDM. CONCLUSIONS: In general, our findings showed that the concurrent use of repeated measures data on Hct, Hb, FBS and RBC in the first and early second trimester of pregnancy might be utilized as an acceptable tool to predict GDM earlier in pregnancy.

Food insecurity is associated with the sleep quality and quantity in adults: a systematic review and meta-analysis.

OBJECTIVE: We evaluated associations between food insecurity (FI) and the quality and quantity of sleep in adults (≥18 years). DESIGN: The current study represented a systematic review and meta-analysis of observational studies. SETTING: Databases of PubMed, Scopus, Embase and Web of Science were searched from inception until 6 June 2022. Meta-analyses were conducted using random-effects models, and effect sizes were reported as OR and 95 % CI. PARTICIPANTS: Data from ten eligible observational studies, including 83 764 participants, were included. RESULTS: FI was associated with an increased risk of poor sleep quality (OR = 1·45; 95 % CI (1·24, 1·70), I2 = 95, P < 0·001, n 7). Besides, subgroup analysis showed increased risk of poor sleep quality corresponding to the severity of FI across mild (OR = 1·31; 95 % CI (1·16, 1·48), I2 = 0 %, P < 0·001, n 5), moderate (OR = 1·49; 95 % CI (1·32, 1·68), I2 = 0 %, P < 0·001, n 5) and severe (OR = 1·89; 95 % CI (1·63, 2·20), I2 = 0 %, P < 0·001, n 5) levels. Similarly, subgroup analysis by sleep problems showed that FI was associated with an increased the risk of trouble falling asleep (OR = 1·39; 95 % CI (1·05, 1·83), I2 = 91 %, P = 0·002, n 3) and trouble staying asleep (OR = 1·91; 95 % CI (1·37, 2·67), I2 = 89 %, P < 0·001, n 3). Moreover, FI was associated with the odds of shorter (OR = 1·14; 95 % CI (1·07, 1·21), I2 = 0 %, P < 0·001, n 4) and longer sleep duration (OR = 1·14; 95 % CI (1·03, 1·26), I2 = 0 %, P = 0·010, n 4). CONCLUSIONS: Collective evidence supports that FI is associated with poor sleep quality and quantity in adults. Preventative and management strategies that address FI may provide health benefits beyond improving nutritional status per se.

Associations between exposure to heavy metals and the risk of chronic kidney disease: a systematic review and meta-analysis.

We performed a systematic review and meta-analysis to examine the relationship between heavy metals (HMs) exposure and the risk of chronic kidney disease (CKD). Databases of Web of Science, Embase, MEDLINE, and Scopus were searched through June 2020 to identify studies assessing the relationships between exposure to HMs (i.e. cadmium, lead, arsenic, mercury) and the risk of CKD, evaluated by decreased estimated glomerular filtration rate (eGFR) and/or increased proteinuria risks in adults (≥18 years). Data were pooled by random-effects models and expressed as weighted mean differences and 95% confidence intervals. The risk of bias was assessed by the Newcastle-Ottawa scale (NOS). Twenty-eight eligible articles (n = 107,539 participants) were included. Unlike eGFR risk (p = 0.10), Cadmium exposure was associated with an increased proteinuria risk (OR = 1.35; 95% CI: 1.13, 1.61; p < 0.001; I2 = 79.7%). Lead exposure was associated with decreased eGFR (OR = 1.12; 95%CI: 1.03, 1.22; p = 0.008; I2 = 87.8%) and increased proteinuria (OR = 1.25; 95% CI: 1.04, 1.49; p = 0.02; I2 = 79.6) risks. Further, arsenic exposure was linked to a decreased eGFR risk (OR = 1.55; 95% CI: 1.05, 2.28; p = 0.03; I2 = 89.1%) in contrast to mercury exposure (p = 0.89). Only two studies reported the link between arsenic exposure and proteinuria risk, while no study reported the link between mercury exposure and proteinuria risk. Exposure to cadmium, lead, and arsenic may increase CKD risk in adults, albeit studies were heterogeneous, warranting further investigations. Our observations support the consideration of these associations for preventative, diagnostic, monitoring, and management practices of CKD.

Disparities in cardio metabolic risk between Black and White women with polycystic ovary syndrome: a systematic review and meta-analysis.

OBJECTIVE: We conducted a systematic review and meta-analysis to summarize and quantitatively pool evidence on cardiometabolic health disparities between Black and White women with polycystic ovary syndrome in the United States in response to the call for further delineation of these disparities in the international evidence-based guideline for the assessment and management of polycystic ovary syndrome. DATA SOURCES: Databases of MEDLINE, Web of Science, and Scopus were searched initially through March 05, 2020, and confirmed on September 11, 2020. STUDY ELIGIBILITY CRITERIA: Observational studies documenting cardiometabolic risk profile (glucoregulatory, lipid profile, anthropometric, and blood pressure status) in Black and White women with polycystic ovary syndrome were included. Studies on children (<17 years old) and pregnant or menopausal-aged women (>50 years) were excluded. The primary outcome was fasting glucose. Furthermore, data on major cardiovascular events (stroke, coronary heart disease, heart failure) and mortality rate (cardiovascular death, total mortality) were evaluated. METHODS: Data were pooled by random-effects models and expressed as mean differences and 95% confidence intervals. Studies were weighted based on the inverse of the variance. Heterogeneity was evaluated by Cochran Q and I2 statistics. Study methodologic quality was assessed by the Newcastle-Ottawa scale. RESULTS: A total of 11 studies (N=2851 [652 Black and 2199 White]) evaluated cardiometabolic risk profile and all had high quality (Newcastle-Ottawa scale score of ≥8). No studies reported on cardiovascular events and mortality rate. Black women had comparable fasting glucose (-0.61 [-1.69 to 2.92] mg/dL; I2=62.5%), yet exhibited increased fasting insulin (6.76 [4.97-8.56] µIU/mL; I2=59.0%); homeostatic model assessment of insulin resistance (1.47 [0.86-2.08]; I2=83.2%); systolic blood pressure (3.32 [0.34-6.30] mm Hg; I2=52.0%); and decreased triglyceride (-32.56 [-54.69 to -10.42] mg/dL; I2=68.0%) compared with White women (all, P≤.03). Groups exhibited comparable total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and diastolic blood pressure (all, P≥.06). CONCLUSIONS: Black women with polycystic ovary syndrome have a greater tendency for an adverse cardiometabolic risk profile (increased insulin, homeostatic model assessment of insulin resistance, and systolic blood pressure) despite lower triglycerides than White women. Our observations support the consideration of these disparities for diagnostic, monitoring, and management practices in Black women and for future guideline recommendations. Given the heterogeneity among studies, future research should address the relative contributions of biologic, environmental, socioeconomic, and healthcare factors to the observed disparities. Furthermore, longitudinal research is required to address patient-pressing complications, including cardiovascular events and mortality rate in Black women with polycystic ovary syndrome as a high-risk yet understudied population.

The relationship between demographic features, anthropometric parameters, sleep duration, and physical activity with ECG parameters in Fasa Persian cohort study.

BACKGROUNDS: Cardiovascular Diseases (CVDs) are the first leading cause of death worldwide. The present study aimed to investigate the relationship between demographics, anthropometrics, sleep duration, physical activity, and ECG parameters in the Fasa Persian cohort study. METHODS: In this cross-sectional study, the basic information of 10,000 participants aged 35-70 years in the Fasa cohort study was used. The data used in this study included demographic data, main Electrocardiogram (ECG) parameters, anthropometric data, sleep duration, and physical activity. Data analysis was performed using t-test, chi-square, and linear regression model. RESULTS: Based on multivariate linear regression analysis results, increased age was significantly associated with all study parameters. Nevertheless, gender and body mass index showed no significant relationship with SV3 and PR. Wrist circumference, hip circumference and waist circumference significantly increased the mean values of the ECG parameters. However, sleep duration was not significantly associated with the ECG parameters. In addition, hypertension was major comorbidity, which was shown to increase the mean values of the ECG parameters. CONCLUSION: Several factors affected the ECG parameters. Thus, to interpret ECGs, in addition to age and gender, anthropometric indices, physical activity, and previous history of comorbidities, such as hypertension and ischemic heart disease, should be taken into consideration.

Trend analysis of disability adjusted life years due to cardiovascular diseases: results from the global burden of disease study 2019.

BACKGROUND: Cardiovascular diseases (CVDs) are the number one cause of global mortality representing about one third of all deaths across the world. The objective of the present study was to model the global trend in disability-adjusted life years (DALY) and its components due to CVD over the past three decades. We also aimed to evaluate the longitudinal relationship between CVD DALY and Human Development Index (HDI) in this period of time. METHODS: The age-standardized rates of years lost due to disability (YLD), years of life lost (YLL) and DALY were extracted for cardiovascular diseases from the Global Burden of Disease (GBD) Study 2019 in years 1990 to 2019. Additionally, the United Nations Development Programme (UNDP) database was used to retrieve HDI values for all world countries at the same period time. The trend analysis was performed using the joinpoint regression model. RESULTS: The obtained revealed a significant downward trend for DALY and its components with the average annual percent change of - 1.0, - 0.3 and - 1.1 per 100,000 population, respectively for DALY, YLD and YLL. We also found that countries with high/very high levels of HDI have remarkably experienced steeper declining slope of trend than those in lower levels of HDI over the study period. CONCLUSIONS: Although the observed decreasing trend of CVD burden is a hopeful message for all world countries, the considerable gap in slope of trend between richer and poorer parts of the world is a serious alarm for health policy makers. Regarding this, there is an urgent need to put more efforts on implementing preventive programs, improving the level of patients' care and providing efficient treatment, especially in regions with lower levels of HDI.

A randomized controlled trial of a lifestyle intervention with longitudinal follow-up on ovarian dysmorphology in women with polycystic ovary syndrome.

OBJECTIVE: Effects of lifestyle modification on reproductive function in polycystic ovary syndrome (PCOS) remain poorly elucidated. We compared the effects of a pulse-based diet (lentils, beans, split peas and chickpeas) with Therapeutic Lifestyle Changes (TLC) diet on ultrasonographic markers of ovarian morphology, hyperandrogenism and menstrual irregularity in PCOS. DESIGN: Randomized controlled trial. PATIENTS: Women with PCOS (18-35 years). MEASUREMENTS: Thirty women randomized to the pulse-based and 31 to TLC groups completed a 16-week intervention without energy restriction. Groups performed aerobic exercise (minimum of 5 days/wk; 45 minutes/d) and received health counselling (monthly) and longitudinal follow-up. Follicle numbers per ovary (FNPO, 2-9 mm), ovarian volume (OV), free androgen index (FAI) and menstrual cycle length were measured pre- and postintervention. RESULTS: Follicle numbers per ovary (mean change ± SD, -10 ± 15), OV (-2.7 ± 4.8 mL), FAI (-3 ± 2) and menstrual cycle length (-13 ± 47 days) decreased over time in both groups (All: P < .01), without group-by-time interactions (All: P ≥ .13). Attrition rate was 33.7% and comparable between groups (P = .94). Adherence to diet intervention negatively correlated with changes in FNPO (r=-0.54), OV (r=-0.35) and FAI (r = -.29) in pooled groups (All: P ≤ .04). Groups maintained reduced OV, FNPO, FAI and menstrual cycles 6 months postintervention; however, decreased FNPO and FAI at 16 weeks tended to revert to baseline levels 12 months postintervention in both groups (All: P ≤ .05). CONCLUSIONS: Both interventions improved ovarian dysmorphology, hyperandrogenism and menstrual irregularity in PCOS, and no diet appeared to be superior at improving reproductive outcomes. Our observations highlight the importance of longitudinal surveillance for sustainable adherence to newly adopted healthy lifestyle behaviours and reproductive health in PCOS (ClinicalTrials.gov identifier, NCT01288638).

Investigating the prevalence of hypertension and its associated risk factors in a population-based study: Fasa PERSIAN COHORT data.

BACKGROUND: A high prevalence rate of hypertension (HTN) and its subsequent serious complications made this disease a major health-treatment concern in many societies. The current study aimed to investigate the prevalence of hypertension and its associated risk factors in Fasa PERSIAN COHORT in south of Iran in 2019. METHODS: This was an analytical-cross sectional study. The study population were the individuals covered by Fasa cohort. Information of the first phase of Fasa Persian cohort in south of Iran was used in this study. Independent t test, chi-square test, analysis of variances, Pearson correlation coefficient, and multiple stepwise regression were used to analyze the obtained data. Thereafter, the data was analyzed using SPSS software version 22, and P value < 0.05 was considered as statistically significant. RESULTS: Out of 10,111 individuals included in the study, 5546 (54.86%) subjects were women and 4565 (45.16%) other were men. The overall prevalence rate of hypertension was estimated as 46.6%. In the present study, (16/1%) of the participants were with HTN stage 1, and (17/9%) of them were with HTN stage 2. The results show that there were significant positive correlations among HTN and age, BMI, HDL, TG, BUN, ALP, smoking, physical activity, cardiovascular diseases, diabetes, and renal failure (P < 0.5). CONCLUSIONS: Prevalence of HTN in this study population is considerable. Therefore, it is suggested that health system should program some plans to prevent hypertension's prevalence and eliminate its risk factors.

Correlation of resting heart rate with anthropometric factors and serum biomarkers in a population-based study: Fasa PERSIAN cohort study.

BACKGROUND: There is a positive association between raised resting heart rate (RHR), and all causes of mortality and shorter life expectancy. Several serum biomarkers and some anthropometric factors can affect the resting heart rate. This study aimed to investigate the determinants of resting heart rate in a large random sample of the Iranian population. MATERIAL AND METHODS: It is a standardized, retrospective study and the subjects were chosen from the baseline survey of the Prospective Epidemiological Research Study in IrAN (PERSIAN) Fasa non-communicable disease cohort study. It was conducted from winter 2014 to summer 2019 and after obtaining informed consent from a random sample, all the eligible subjects were enrolled. All anthropometric factors and biologic laboratory factors were collected and analyzed by implement smoothly clipped absolute deviation (SCAD) linear regression and SCAD quantile regression. The comparisons between males and females were done via independent T-test. RESULTS & CONCLUSION: A total number of 9975 persons from 35 to 90 years old were included. The overall median resting heart rate was 74 (interquartile range:66-80). Mean age has no important difference between males and females (P = 0.79) but, resting heart rate was significantly higher in females (76.6 versus 71.4, P < 0.001). All anthropometric factors except wrist circumference were higher in females (P < 0.05). Age has an adverse effect on resting heart rate and also, there was a direct association between resting heart rate and systolic blood pressure and blood glucose. Alpha-blockers (coefficient = 5.2) and Beta1-blockers (coefficient = - 2.2) were the most effective drugs with positive and negative effects on resting heart rate respectively. Lower hemoglobin, obesity, and more body mass index, and more low-density lipoprotein were associated with more resting heart rate. Continuing the monitoring of this sample via our cohort study and put to action multinational prospective researches with large sample sizes and long follow-ups can lead to more precise results and better scientific judgments.

Deep skin wound healing potential of lavender essential oil and licorice extract in a nanoemulsion form: Biochemical, histopathological and gene expression evidences.

Cutaneous wound healing is one of the public health interests. This study aimed to investigate the effects of nanoemulsion cream containing lavender essential oil and licorice extract on the healing of deep skin wound in a rat model. Eighty-five male Wistar rats were randomly divided into five groups including untreated defects as negative control and defects treated with vehicle ointment, lavender essential oil and licorice extract in emulsion and nanoemulsion forms, and phenytoin 1% as the positive control with an excisional wound on the dorsal neck of each rat. On days 2, 7 and 14 oxidative stress factors were evaluated in wound tissue homogenates. The expression of transforming growth factor-ß (TGF-ß), and type I and type III collagen genes were evaluated. Also, wound tissue samples were processed for Hematoxylin & Eosin and Masson-Trichrome staining. Nanoemulsion reduced the wound area more than other groups significantly. Real-time PCR data demonstrated that nanoemulsion and phenytoin groups have shown the best result in increasing TGF-ß1, Type I and type III collagen genes expression compared to the other groups. Reduction in lipid peroxidation level and increasing in SOD and GPx activity was also significant in the nanoemulsion and phenytoin groups. The formation of granular tissue likewise the appearance of collagen in nanoemulsion and phenytoin groups were faster than the other groups. Nanoemulsion cream containing lavender essential oil and licorice extract exhibited a promising wound healing potential towards the excisional wound model in rats.

Comprehensive Evaluation of Type 2 Diabetes and Cardiovascular Disease Risk Profiles in Reproductive-Age Women with Polycystic Ovary Syndrome: A Large Canadian Cohort.

OBJECTIVE: This study compared the prevalence of metabolic syndrome (MetS) and characterized type 2 diabetes (DM2) and cardiovascular disease (CVD) risk profiles between Canadian women with polycystic ovary syndrome (PCOS) and healthy women recruited from the general population. Furthermore, within the PCOS cohort, the study contrasted the CVD and DM2 risk profiles of women with or without MetS. METHODS: Measures of MetS (International Diabetes Federation; National Heart, Lung, and Blood Institute; and the American Heart Association definition), DM2 (Diabetes Canada Clinical Guidelines), and CVD risk factors (Androgen Excess and Polycystic Ovary Syndrome Society statement) were evaluated for 237 women with PCOS (Androgen Excess and PCOS Society definitions) and 42 controls (aged 18-36) in a prospective observational study (Canadian Task Force Classification II-2). RESULTS: The prevalence of MetS was 29.5% in the PCOS group, which was approximately six-fold higher than age-matched controls (P < 0.001). Women with PCOS exhibited higher glucose abnormality, acanthosis nigricans, total cholesterol to high-density lipoprotein cholesterol ratio (TC/HDL-C), and lower sex hormone-binding globulin concentrations when compared with controls after accounting for differences in the BMI (P < 0.01). Further, women with PCOS and MetS exhibited exacerbated insulin and glucose responses to a 75-g oral glucose tolerance test and greater acanthosis nigricans, hirsutism, TC/HDL-C, TC, and sex hormone-binding globulin concentrations compared with their BMI-adjusted counterparts without MetS (P < 0.05). CONCLUSION: Canadian reproductive-age women with PCOS have a high prevalence of MetS and exhibit adverse cardiometabolic risk factors that warrant early screening and regular monitoring across their reproductive lifespan.

Iran's international collaborative articles in medical sciences.

Background: Forecasting is the process of predicting future behavior. In reviewing databases, no predicted value associated with international collaboration publications in Iran was found. Thus, the present study aimed at forecasting Iran's international collaborative articles in medical sciences. Methods: The number of Iran's articles and international collaborative articles in medical sciences written over 56 years was extracted from SCOPUS. Data were extracted from 1960 up to 2016. The time series method was used for forecasting using the Minitab software Version 17. Results: There was no increase in the number of medical articles from Iran from 1960 to 2001. However, the data showed incremental growth between 2001 and 2016. This was similar to Iran's medical sciences international collaboration articles. In 2016, the percentage of Iran's international collaboration articles was 15.2, which is expected to reach 19.9 in 2025. Conclusion: An investigation was performed on the number of international collaboration articles in the field of medical sciences in Iran. Future trends show an incremental growth. The number of Iran's articles can be increased with international cooperation. However, an increase or decrease in Iran's articles without international cooperation has to be investigated.

Electrosurgery and clinical applications of electrosurgical devices in gynecologic procedures.

Background: Electrosurgery is widely used in reproductive related surgeries and technological advancements to improve efficacy and reduce potential complications. However, some reports have indicated lack of sufficient knowledge and training about basic principles and technical aspects of electrosurgery among obstetricians and gynecologists. Methods: In this paper we present a summary on basic concepts and principles of electrosurgery and review the recent evidence on the use of electrosurgical devices in gynecologic procedures including endometrial ablation, gynecologic malignancies, loop electrode excision procedure (LEEP), and infertility. Result: Considering the extensive use of these technologies in reproductive related surgeries, procedures including laparoscopy, hysteroscopy, and loop procedures further highlights the importance of more detailed training in this field. Gynecologists must learn the basics in more detail and update their knowledge on the growing body of evidence regarding the advancements of these technologies to reduce potential complications and select the most cost-effective treatment options for each patient. Conclusion: Try to understanding the underlying biophysical principles and more in-depth familiarity with various electrosurgical devices could lead to less complications and optimize evidence-based gynecological practice.
