Abstract
Sex differences in late-life memory decline may be explained by sex differences in dementia risk factors. Episodic memory and dementia risk factors were assessed in young, middle-aged and older adults over 12 years in a population-based sample (N = 7485). For men in midlife and old age, physical, cognitive and social activities were associated with less memory decline, and financial hardship was associated with more. APOE e4 and vascular risk factors were associated with memory decline for women in midlife. Depression, cognitive and physical activity were associated with memory change in older women. Incident midlife hypertension (β = - 0.48, 95% CI - 0.87, - 0.09, p = 0.02) was associated with greater memory decline in women and incident late-life stroke accounted for greater memory decline in men (β = - 0.56, 95% CI - 1.12, - 0.01), p = 0.05). Women have fewer modifiable risk factors than men. Stroke and hypertension explained sex differences in memory decline for men and women respectively.

Abstract
INTRODUCTION Despite common perceptions, coronary artery disease (CAD) is not a male-specific condition, and sex-based differences do occur in many aspects, including clinical outcomes after percutaneous coronary intervention (PCI) with stent implantation. New-generation drug-eluting stents (DES) significantly improved post-PCI outcomes. However, no sex-specific guidelines on PCI and the use of DES are available as current evidence was derived from clinical trials enrolling predominantly male patients. AREAS COVERED This review aims at exploring sex-based disparities in CAD characteristics and manifestations, and comparing PCI outcomes and the efficacy and safety profiles of DES according to sex. In addition, a critical approach to trials' interpretation with an analysis of sources of bias is provided to inform future research and clinical practice. EXPERT OPINION Sex gap in clinical outcomes after PCI with DES implantation is narrowing due to improved performances of new-generation DES. However, scientific research and biomedical engineering are striving to optimize DES profiles and generate new iterations of devices. At the same time, gender initiatives and sex-specific trials are accruing to overcome current issues in the field. Advances in these areas will foster improvements in early and long-term clinical outcomes of both women and men.

Abstract
Background Currently, there have been studies showing a correlation between sex differences and prognosis. Nevertheless, the conclusions of clinical studies on sex-based differences are controversial. We aimed to evaluate the effect of sex on the short- and long-term survival of critically ill patients with sepsis. Methods We use the critical care database of the healthcare information mart. Cox models were conducted to determine the relationship of 28-day and 1-year mortality with a different sex. Interaction and stratified analyses were conducted to test whether the effect of sex differed across age and sequential organ failure assessment (SOFA) score subgroups. Results A total of 12,321 patients were enrolled in this study. The Cox regression analysis showed that the 28-day and 1-year mortality rates of female patients were significantly lower than those of male patients by 10% and 8%, respectively (hazard ratio [HR]=0.90, 95% confidence interval [CI] 0.83–0.98, and HR=0.92, 95% CI 0.87–0.97, respectively). The effects of the association between sex and 28-day and 1-year mortality were broadly consistent for age and the SOFA subgroup variables. Only age was observed to have significant interactions in the 1-year mortality (P=0.0177). Compared with male patients, female patients aged <50 years had a long-term survival advantage (HR=0.77, 95% CI 0.62–0.95). In contrast, we did not find sex-based differences in the short- and long-term survival for patients aged ≥50 years. Conclusion In the current retrospective large database review, the 28-day and 1-year mortality were significantly lower in females than in male patients among critically ill patients with sepsis. Notably, there was an interaction between age and sex, and whether female-associated hormones or other contributing factors affect the clinical outcomes of patients with sepsis needs to be further researched.

Abstract
OBJECTIVES To examine the effects of physical activity (PA) in adults with or without prehypertension at baseline on systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension risk by gender. METHODS A total of 5986 men and 6525 women (≥18 years old) without hypertension-related disease at baseline who attended surveys from China Health and Nutrition Survey (1991-2015) at least twice were selected. In terms of the nested data structure, three-level random intercept growth model and three-level logistic regression were used to estimate the relationship between the PA and SBP/DBP or hypertension risk. RESULTS The incidence of hypertension increased from 10.86% in 1991 to 20.34% in 2015, and the median of PA dropped from 408 MET·h/week in 1991 to 104 MET·h/week in 2015. After adjusting confounders, PA in the third and fourth quartiles decreased SBP (by 0.98 and 0.96 mm Hg, p < 0.05) and DBP (by 0.30 and 0.38 mm Hg, p < 0.05), and it reduced the odds of hypertension by 12 and 15% (p < 0.05), compared with PA in the lowest quartile. For normotensive women in the third quartile of PA and prehypertensive women in the fourth quartile of PA, the risk of hypertension was reduced 15 and 22%, compared with women in the lowest quartile of PA. CONCLUSIONS Physical activity should be improved to the relatively high level to be effective in controlling blood pressure. Normotensive women had an association between physical activity and SBP, DBP, and the risk of hypertension.

Abstract
Introduction In women, an increase in blood pressure is observed after the menopause. However, the confounding effect of aging and comorbidities should be taken into account. Current guidelines don’t recommend any specific treatment of post-menopausal hypertension. This study aimed to assess the influence of gender on the outcome of hypertension treatment in patients above 40 years old. Material and methods Data for this retrospective, single-center study were collected from the disease cards of hypertensive pharmacologically treated patients hospitalized on the cardiological ward. 268 patients, aged over 40, were divided into two groups: women and men. Additional data regarding compliance and efficacy of treatment after hospitalization were obtained in phone interview. Statistical analysis was performed using the IBM SPSS Statistics25 package. Results We analyzed the data in term of comorbidities and medical history of cardiological interventions. The significant differences between studied groups were noted only in the frequency of hyperlipidemia and coronary artery bypass graft, both were more often in men. Significantly more men have been using combined products (24 men – 32.4%) vs. 40 women (20.6%) (p = 0.03). Regarding the drug classes in treatment of hypertension, the only significant difference was observed in the frequency of alfa-blocker use (more often in men). We did not observe any significant difference in the willingness to participate in follow-up between women and men (146, 75.3% vs. 57, 77%, respectively, p = 0.45). There were no significant differences in the follow-up results. Conclusions In the studied group of patients, gender did not affect the outcome of hypertension treatment.

Abstract
Cardiovascular autonomic dysfunction is associated with end organ damage and increased risk of mortality. Menopause and metabolic syndrome increase the risk for cardiorenal complications. In this study, we investigated the effects of aerobic or resistance exercise training on autonomic control of circulation and renal oxidative stress in a model of menopause and metabolic syndrome. Female Wistar rats and spontaneously hypertensive rats (SHR) were divided into 5 groups (n = 8): control (C), hypertensive (H), and sedentary (FHO), aerobic trained (FHOTa) and resistance trained (FHOTr) oophorectomized hypertensive treated with fructose (100 mg/mL drink water for 19 weeks). The FHO group presented increased vascular sympathetic modulation (LF-SBP), impaired baroreflex sensitivity (BRS) associated with increased blood pressure (BP) when compared to the H group. Aerobic exercise training enhanced tachycardic responses, while resistance training improved bradycardic responses to BP changes, thus ameliorating BRS. Moreover, despite unchanged BP, both exercise training protocols were effective in preventing increase in LF-SBP, reduction in systemic nitric oxide bioavailability (NOx), and increase in oxidative stress in the renal tissue, by decreasing lipid and protein oxidation in renal tissue. Positive correlation between LF-SBP and renal lipoperoxidation (r = 0.63, p < 0.05), as well as a negative correlation between NOx and renal lipoperoxidation (r = -0.66, p < 0.05) were observed. In conclusion, both aerobic and resistance exercise training were effective in improving autonomic control of circulation and reducing renal oxidative stress, thus attenuating the deleterious effects induced by arterial hypertension and fructose overload in female rats after ovarian hormone deprivation.

Abstract
Cardiovascular disease (CVD) is the leading cause of death in women, who have a notable increase in the risk for this disease after menopause and typically develop coronary heart disease several years later than men. This observation led to the hypothesis that the menopause transition (MT) contributes to the increase in coronary heart disease risk. Over the past 20 years, longitudinal studies of women traversing menopause have contributed significantly to our understanding of the relationship between the MT and CVD risk. By following women over this period, researchers have been able to disentangle chronological and ovarian aging with respect to CVD risk. These studies have documented distinct patterns of sex hormone changes, as well as adverse alterations in body composition, lipids and lipoproteins, and measures of vascular health over the MT, which can increase a woman's risk of developing CVD postmenopausally. The reported findings underline the significance of the MT as a time of accelerating CVD risk, thereby emphasizing the importance of monitoring women's health during midlife, a critical window for implementing early intervention strategies to reduce CVD risk. Notably, the 2011 American Heart Association guidelines for CVD prevention in women (the latest sex-specific guidelines to date) did not include information now available about the contribution of the MT to increased CVD in women. Therefore, there is a crucial need to discuss the contemporary literature on menopause and CVD risk with the intent of increasing awareness of the significant adverse cardiometabolic health-related changes accompanying midlife and the MT. This scientific statement provides an up-to-date synthesis of the existing data on the MT and how it relates to CVD.

Abstract
Current guidelines recommend statin therapy for all adult patients with coronary artery disease irrespective of sex. Over recent years, some concerns have been raised concerning the effects of statins on endogenous steroid hormones synthesis. The aim of this review was to summarize the effects of statins on endogenous sex hormones in order to clarify their role and safety in different clinical settings. Results suggest that HMG-CoA inhibitors may slightly impair adrenal and/or gonadal steroid hormone production. In men, statins do not cause any clinically-relevant harmful effects on erectile function and spermatogenesis and, in women, statins have beneficial effects in treatment of polycystic ovary syndrome (PCOS). Additional research is needed to provide specific clinical recommendations concerning this topic.

Abstract
BACKGROUND Epidemiological differences between men and women have been reported with regards to sepsis, influenza and severe coronavirus infections including SARS-CoV and MERS-CoV. AIM To systematically review the literature relating to men versus women on SARS-CoV-2 in order to seek differences in disease characteristics (e.g. infectivity, severity) and outcomes (e.g. mortality). METHODS We searched 3 electronic databases up or observational studies reporting differences between men and women in the SARS-CoV-2 disease characteristics stated. We identified and included 47 studies, reporting data for 21,454 patients mainly from China. RESULTS The unadjusted mortality rates of men were higher than those of women, with a mortality OR 0.51 [0.42, 0.61] (p<0.001) for women. The proportion of men presenting with severe disease and admitted to the intensive care unit (ICU) was also higher than that of women (OR 0.75 [0.60-0.93] p<0.001 and OR 0.45 [0.40-0.52] p<0.001 respectively). Adjusted analyses could not be conducted due to lack of data. CONCLUSION COVID-19 may be associated with worse outcomes in males than in females. However, until more detailed data are provided in further studies enabling adjusted analysis, this remains an unproven assumption.

Abstract
COVID-19 displays a sex-biased behavior with a higher rate of intensity and mortality in men. In that sense, COVID-19 deflects-off the typical trend of many viral infections which are characterized by a higher rate of intensity and prevalence in males, yet a higher female mortality rate. Severity and mortality rates of COVID-19 are associated with several underlying diseases, which exhibit significant self-sufficient male-biased dimorphism, thus are at times hypothesized to be the ones responsible to tilt mortality balance toward higher men death in COVID-19. Yet, similar comorbidities prevail in other viral infections, raising curiosity to what makes COVID-19 unique? The answer may lay in the involvement of renin-angiotensin system and ACE2 receptor in COVID-19 progression, 2 players which are significant contributors to the fatality of COVID-19. A structured difference is evident in the expression and function of RAS and ACE2 between the sexes, presumably tipping over mortality rate tendency toward male-risk factor.

Abstract
Background Both triglyceride glucose-body mass index (TyG-BMI) and non-alcoholic fatty liver disease (NAFLD) are linked to insulin resistance (IR). Prospective studies linking TyG-BMI to NAFLD have been limited by short follow-up. This study investigated the longitudinal association between TyG-BMI and NAFLD occurrence in the non-obese Chinese individuals. Methods This study determined TyG-BMI at baseline and the incidence of NAFLD at follow-up and performed a post hoc analysis of a prospective cohort study that involved assessing the risk of NAFLD in non-obese Chinese residents from January 2010 to December 2014. The incidence of NAFLD during the 5-year follow-up was identified as the endpoint. Cox proportional hazards regression analysis was used to evaluate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the incidence of NAFLD. Receiver operating characteristic (ROC) curve analysis was conducted to estimate the predictive power of TyG-BMI and its components for NAFLD. Subgroup analysis was performed to better understand other factors that may affect the association between TyG-BMI and NAFLD to identify potential special populations. Results During the follow-up period, 841 (8.61%) of 9767 non-obese subjects who met the screening criteria were diagnosed with NAFLD. After confounding factors were fully adjusted for, the HR of NAFLD was 3.09 (95% CI 2.63–3.63) per standard deviation (SD) increase in TyG-BMI. Furthermore, TyG-BMI had a strong predictive value (area under ROC = 0.85; 95% CI 0.84–0.86) for the incidence of NAFLD, with a specificity of 0.73 and sensitivity of 0.82. Additionally, in the male population, each SD increase in TyG-BMI was linked to an increased risk of NAFLD (HR = 2.85, 95% CI 2.30–3.53), but the risk was higher in the female population (HR = 3.58, 95% CI 2.80–4.60). Gender and TyG-BMI interacted significantly with NAFLD incidence (P < 0.0001). Conclusion In the normolipidaemic and non-obese subset of the Chinese population, an increase in TyG-BMI is related to an increased incidence of NAFLD. TyG-BMI may have clinical significance in identifying groups at high risk of NAFLD.

Abstract
There is little evidence about the impact of birth month on total and cardiovascular disease mortality in developing countries. We evaluated these associations using the population health registration data of Hefei City, China from 2014 to 2017. After controlling for the fixed effects of gender, education, and occupation, we fitted the Cox proportional hazard regression model to assess the relationship between birth month and mortality. Hazard ratio (HR) with corresponding 95% confidence interval (CI) was calculated. All data analyses were performed by R 3.6.0 software. The data of 44 665 participants were analyzed in the study. Compared to people born in January, people born between May and October had higher total and cardiovascular mortality, being highest in June, respectively, HR: 1.130 (95%CI: 1.074 to 1.190) and HR: 1.200 (95%CI: 1.115 to 1.290). After stratification by gender, males born in June had highest risk total and cardiovascular mortality, with an increase in risk of 14.8% and 24.7%, respectively. For females, highest risk of total mortality was increased by 11.1% in those born in July, while those born in December had highest increase in cardiovascular mortality risk by 15.7%. Our results indicate in Hefei City, China month of birth is associated with total and cardiovascular disease mortality.

Abstract
Purpose: We analyzed blood pressure (BP) changes in transgender male adolescents treated with gonadotropin-releasing hormone analogs (GnRHa) and after adding testosterone treatment. Methods: This was a retrospective pilot study. Outcome measures included systolic BP (SBP) and diastolic BP (DBP) before and after GnRHa initiation and after adding testosterone. Results: Fifteen transgender male adolescents received GnRHa. DBP percentiles increased significantly after GnRHa treatment (from 55.9% ± 26.4 to 73.6% ± 9.4, p = 0.019). BP levels did not meet criteria for hypertension. DBP percentiles were restored after adding testosterone. Conclusion: GnRHa may increase DBP in transgender male adolescents, and testosterone treatment may restore it. Further larger studies are indicated.

Abstract
For normal-weight population, the management of prehypertension may be more beneficial by identifying insulin resistance (IR) status than relying solely on traditional indicators of obesity. We investigated the association of triglyceride glucose (TyG) index, a simple surrogate marker of IR, and its combination of obesity indices with prehypertension in lean individuals. A total of 105 070 lean adults without hypertension were included in this analysis. Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), and TyG were calculated according to the corresponding formula; TyG-BMI, TyG-WC, and TyG-WHtR were calculated by multiplying the corresponding two parameters. Gardner-Altman plots, partial correlation, and logistic regression analyses were applied to explore the associations in continuous variables and quartiles. The prehypertensive ones had higher mean values of TyG, TyG-BMI, TyG-WC, and TyG-WHtR than normotensive individuals. All the four indicators showed positive correlations with systolic blood pressure and diastolic blood pressure. After full adjustment, only TyG-BMI and TyG-WC were significantly associated with prehypertension in both genders. Furthermore, TyG-BMI had the highest OR for prehypertension. Our study showed that TyG-BMI might be an accessible and complementary monitor in the hierarchical management of non-obese prehypertensive patients.

Abstract
Hypertension represents one of the most important and most frequent cardiovascular risk factors responsible for heart failure (HF) development. Both sexes are equally affected by arterial hypertension. The difference is lying in the fact that prevalence of hypertension as well as hypertension-induced target organ damage varies during lifetime due to substantial variation of sex hormones in women. Left ventricular (LV) structural, functional, and mechanical changes induced by hypertension are well-known complications that occur in both sexes and they are responsible for HF development. However, their prevalence is significantly different between women and men, which could potentially explain the variation in HF occurrence and prognosis between the sexes. Studies have shown that the prevalence of left ventricular hypertrophy is higher in men. The data are not consistent regarding LV diastolic dysfunction and a similar report has been given for LV mechanical changes. Most investigations agree that LV longitudinal strain is lower among hypertensive men. However, even in the healthy population, men have lower LV longitudinal strain and the cutoff values are still missing. Therefore, it would be difficult to draw the conclusion that LV mechanical dysfunction is more prevalent among men. The main mechanisms responsible for sex-related LV remodeling are sex hormones and their influence on biohumoral systems. This review provides an updated overview of the available data about sex-related LV remodeling, as well as potential mechanisms for these changes, in the patients with arterial hypertension.

Abstract
Background Hypertension prevalence increases when socioeconomic status decreases but gender differences in the relationship between socioeconomic status and hypertension have been less studied. This work aimed to explore the pattern of associations between three indicators of socioeconomic status at individual, household, and municipal levels with hypertension across genders in a large sample of French adults from the CONSTANCES cohort. Methods Using data at inclusion from 59 805 participants (52% women) aged 25–69 years and recruited between 2012 and 2015, multilevel log-Poisson regressions with robust variance estimates were used to assess the associations of Relative Index of Inequality in education, monthly income per consumption unit and residential deprivation with hypertension. Modifying effects of gender and age in those associations were tested. Results Hypertension prevalence was higher in men than in women. Steep socioeconomic gradients of hypertension were observed for the three socioeconomic indicators in both genders and from the youngest to the oldest age class. Socioeconomic inequalities, especially educational inequalities, were larger among women than men: Relative Index of Inequality for highest versus lowest education among the 25–34 years were 0.43 [95%-confidence interval = 0.28–0.67] in women and 0.70 [95%-confidence interval = 0.53–0.92] in men. With increasing age, socioeconomic gradients of hypertension eased in men and even more in women so that gender differences decreased. Conclusions In this cross-sectional analysis of a large sample of adults, prevalence of hypertension was higher in men than in women. Moreover, socioeconomic status and especially education displayed a stronger association with hypertension prevalence in women compared to men. Reducing inequalities in hypertension may require gender-specific approaches.

Abstract
Hypertension is the leading cause of preventable mortality worldwide, contributing to over 9 million deaths per annum, predominantly owing to cardiovascular disease. The association of obesity, physical inactivity and alcohol with elevated blood pressure (BP) is firmly established. Weight loss or other dietary strategies, such as the Dietary Approaches to Stop Hypertension (DASH) diet, have been shown to be effective in lowering BP. Additionally, specific nutrients are recognised to contribute to BP, with higher sodium intake linked with an increased risk of hypertension, while potassium is associated with a reduced risk of hypertension. Of note, emerging evidence has identified a novel role for one-carbon metabolism and the related B vitamins, particularly riboflavin, in BP. Specifically in adults genetically at risk of developing hypertension, owing to the common C677T polymorphism in MTHFR, supplemental riboflavin (co-factor for MTHFR) was shown in randomised trials to lower systolic BP by up to 13 mmHg. A BP response to intervention of this magnitude could have important clinical impacts, given that a reduction in systolic BP of 10 mmHg is estimated to decrease stroke risk by 40%. This review aims to explore the factors contributing to hypertension across the lifecycle and to critically evaluate the evidence supporting a role for nutrition, particularly folate-related B vitamins, in BP and risk of hypertension. In addition, gaps in our current knowledge that warrant future research in this area, will be identified.

Abstract
Background Pulmonary hypertension is prevalent in black individuals, especially women. Elevated pulmonary artery systolic pressure (PASP) is associated with significant morbidity and mortality. Methods and Results We developed linear and proportional hazards models to examine potential gender‐related differences in risk factors for elevated PASP (estimated by transthoracic echocardiography) and PASP‐associated clinical outcomes (incident heart failure admissions and mortality) in JHS (Jackson Heart Study) participants. JHS is a prospective observational cohort study of heart disease in blacks from the Jackson, Mississippi, metropolitan area. The study cohort included participants with measurable transtricuspid gradients (n=3286) at the time of first/baseline examination, 2000–2004. The median age (interquartile range) of patients at baseline was 57.8 years (18.6 years) with 67.5% being women. The median PASP at baseline was higher in women (men: 26 mm Hg [interquartile range 8], women: 27 mm Hg [interquartile range 9]. In multivariate linear regression analyses with PASP, significant gender interactions were noted for age, chronic lung disease, pulse pressure, and obstructive spirometry. In exploratory analyses stratified by gender, body mass index, and obstructive and restrictive spirometry patterns were associated with PASP in women, and chronic lung disease was associated with PASP in men. Age and pulse pressure had stronger associations with PASP in women compared with men. There was a significant interaction between gender and PASP for heart failure admissions but not mortality. Conclusions Specific cardiopulmonary risk factors are associated with elevated PASP in women and men. Women with elevated PASP have a higher risk of incident heart failure admissions. Future research is needed to understand associated gender‐specific mechanisms that can help identify targeted prevention and management strategies for patients with elevated PASP.

Int J Endocrinol 2020; 2020:8849641.

Abstract
INTRODUCTION Androgen signaling comprises nongenomic and genomic pathways. Nongenomic actions are not related to the binding of the androgen receptor (AR) and occur rapidly. The genomic effects implicate the binding to a cytosolic AR, leading to protein synthesis. Both events are independent of each other. Genomic effects have been associated with different pathologies such as vascular ischemia, hypertension, asthma, and cardiovascular diseases. Catecholamines play a crucial role in regulating vascular smooth muscle (VSM), airway smooth muscle (ASM), and cardiac muscle (CM) function and tone. OBJECTIVE The aim of this review is an updated analysis of the role of androgens in the adrenergic system of vascular, airway, and cardiac myocytes. Body. Testosterone (T) favors vasoconstriction, and its concentration fluctuation during life stages can affect the vascular tone and might contribute to the development of hypertension. In the VSM, T increases α1-adrenergic receptors (α 1-ARs) and decreases adenylyl cyclase expression, favoring high blood pressure and hypertension. Androgens have also been associated with asthma. During puberty, girls are more susceptible to present asthma symptoms than boys because of the increment in the plasmatic concentrations of T in young men. In the ASM, β 2-ARs are responsible for the bronchodilator effect, and T augments the expression of β 2-ARs evoking an increase in the relaxing response to salbutamol. The levels of T are also associated with an increment in atherosclerosis and cardiovascular risk. In the CM, activation of α 1A-ARs and β 2-ARs increases the ionotropic activity, leading to the development of contraction, and T upregulates the expression of both receptors and improves the myocardial performance. CONCLUSIONS Androgens play an essential role in the adrenergic system of vascular, airway, and cardiac myocytes, favoring either a state of health or disease. While the use of androgens as a therapeutic tool for treating asthma symptoms or heart disease is proposed, the vascular system is warmly affected.

Abstract
BACKGROUND Epidemiological differences between men and women have been reported with regards to sepsis, influenza and severe coronavirus infections including SARS-CoV and MERS-CoV. AIM To systematically review the literature relating to men versus women on SARS-CoV-2 in order to seek differences in disease characteristics (e.g. infectivity, severity) and outcomes (e.g. mortality). METHODS We searched 3 electronic databases up or observational studies reporting differences between men and women in the SARS-CoV-2 disease characteristics stated. We identified and included 47 studies, reporting data for 21,454 patients mainly from China. RESULTS The unadjusted mortality rates of men were higher than those of women, with a mortality OR 0.51 [0.42, 0.61] (p<0.001) for women. The proportion of men presenting with severe disease and admitted to the intensive care unit (ICU) was also higher than that of women (OR 0.75 [0.60-0.93] p<0.001 and OR 0.45 [0.40-0.52] p<0.001 respectively). Adjusted analyses could not be conducted due to lack of data. CONCLUSION COVID-19 may be associated with worse outcomes in males than in females. However, until more detailed data are provided in further studies enabling adjusted analysis, this remains an unproven assumption.

Abstract
CONTEXT Steroid hormones are important regulators of physiological processes in humans and are under genetic control. A link to coronary artery disease (CAD) is supposed. OBJECTIVE Our main objective was to identify genetic loci influencing steroid hormone levels. As a secondary aim, we searched for causal effects of steroid hormones on CAD. DESIGN We conducted genome-wide meta-association studies for eight steroid hormones: cortisol, dehydroepiandrosterone sulfate (DHEAS), estradiol, and testosterone in two independent cohorts (LIFE-Adult, LIFE-Heart, maximum n = 7667), and progesterone, 17-hydroxyprogesterone, androstenedione, and aldosterone in LIFE-Heart only (maximum n = 2070). All genome-wide significant loci were tested for sex interactions. Furthermore, we tested whether previously reported CAD single-nucleotide polymorphisms were associated with our steroid hormone panel and investigated causal links between hormone levels and CAD status using Mendelian randomization (MR) approaches. RESULTS We discovered 15 novel associated loci for 17-hydroxyprogesterone, progesterone, DHEAS, cortisol, androstenedione, and estradiol. Five of these loci relate to genes directly involved in steroid metabolism, that is, CYP21A1, CYP11B1, CYP17A1, STS, and HSD17B12, almost completing the set of steroidogenic enzymes with genetic associations. Sexual dimorphisms were found for seven of the novel loci. Other loci correspond, for example, to the WNT4/β-catenin pathway. MR revealed that cortisol, androstenedione, 17-hydroxyprogesterone, and DHEA-S had causal effects on CAD. We also observed enrichment of cortisol and testosterone associations among known CAD hits. CONCLUSION Our study greatly improves insight into genetic regulation of steroid hormones and their dependency on sex. These results could serve as a basis for analyzing sexual dimorphism in other complex diseases.

[PMID: 31548618 DOI: 10.1038/s41371-019-0263-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 06/26/2019] [Accepted: 07/17/2019] [Indexed: 12/13/2022]
Abstract
Timely awareness of hypertension is among the most crucial components in reducing the burden of hypertension. However, there is limited information about the awareness of hypertension in northern China. Therefore, in this cross-sectional study, we aimed to investigate the awareness of hypertension and its associated factors in the Jilin province in China; the study was conducted between July 2014 and December 2015 in four cities and four rural counties in the Jilin province as part of a national study. A stratified multistage random-sampling method was used to select a representative sample: a total of 15,206 participants aged ≥15 years were initially recruited, among which 14,956 were finally included in the survey. The awareness of hypertension in the Jilin province was found to be 42.3%. Moreover, the awareness of hypertension was associated with age, sex, region, marital status, body mass index, and family history of hypertension or coronary artery disease. Employment was associated with a lower awareness in rural areas, whereas high education was associated with a higher awareness in urban areas. Policies targeting specific subgroups may be helpful in increasing the awareness of hypertension in the Jilin province.

Impact of Patient Beliefs on Blood Pressure Control in the General Population: Findings from the Population-Based STAAB Cohort Study. Int J Hypertens 2019; 2019:9385397. [PMID: 31467700 PMCID: PMC6699330 DOI: 10.1155/2019/9385397] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 06/19/2019] [Accepted: 07/07/2019] [Indexed: 01/15/2023] Open
Abstract
Background. Effective antihypertensive treatment depends on patient compliance regarding prescribed medications. We assessed the impact of beliefs related towards antihypertensive medication on blood pressure control in a population-based sample treated for hypertension. Methods. We used data from the Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB) study investigating 5000 inhabitants aged 30 to 79 years from the general population of Würzburg, Germany. The Beliefs about Medicines Questionnaire German Version (BMQ-D) was provided in a subsample without established cardiovascular diseases (CVD) treated for hypertension. We evaluated the association between inadequately controlled hypertension (systolic RR >140/90 mmHg; >140/85 mmHg in diabetics) and reported concerns about and necessity of antihypertensive medication. Results. Data from 293 participants (49.5% women, median age 64 years [quartiles 56.0; 69.0]) entered the analysis. Despite medication, half of the participants (49.8%) were above the recommended blood pressure target. Stratified for sex, inadequately controlled hypertension was less frequent in women reporting higher levels of concerns (OR 0.36; 95%CI 0.17-0.74), whereas no such association was apparent in men. We found no association for specific-necessity in any model. Conclusion. Beliefs regarding the necessity of prescribed medication did not affect hypertension control. An inverse association between concerns about medication and inappropriately controlled hypertension was found for women only. Our findings highlight that medication-related beliefs constitute a serious barrier of successful implementation of treatment guidelines and underline the role of educational interventions taking into account sex-related differences.

Abstract
INTRODUCTION Hypertension is significantly contributing to global mortality and morbidity and has been identified as the most important modifiable risk factor for early development of cardiovascular diseases (CVD). AIM The aim of this study was to investigate the efficacy of different combinations of antihypertensive therapy on blood pressure, arterial stiffness and peripheral resistance in patients with essential hypertension using the brachial oscillometric ambulatory blood pressure monitor. METHODS This study was designed as an observational, prospective, multi centric study conducted in eight primary care centers of the Health Center of Canton Sarajevo during the period of six months. The study included 655 participants, both genders, aged between 30 and 75, who were diagnosed with hypertension according to the ESC/ESH guidelines. Participants were divided into six treatment groups based on the hypertensive drug therapy they were using; lisinopril, losartan or valsartan alone or in combination with hydrochlorothiazide (A, B and C group respectively) or combination of lisinopril, losartan or valsartan with/without hydrochlorothiazide together with amlodipine (D, E and F respectively). The participants were monitored at baseline, after 3 and 6 months (1st and 2nd follow-up). Brachial oscillometric ambulatory blood pressure monitor was used for measuring systolic (SBP), diastolic (DBP), pulse pressure (PP), pulse wave velocity (PWV) and peripheral resistance (PR). RESULTS SBP, DPB, PP, and PWV significantly decreased from baseline to 2nd follow-up in all treatment groups. The mean reductions in SBP were from -11.7 (95%CI; 9.3- 14.1) to -23.2 (95%CI; 18.3-28.1) mmHg and DBP reductions varied from -5.5 (95%CI; 3.9- 7.1) to -13.4 (95%CI; 7.7-19.1) mmHg. PWV decreased in all treatment groups (from -3.3% to -8.2%). Treatment regiment was not associated with significant differences in SBP, DBP, PP or PWV reductions or their values measured at 2nd follow-up. Peripheral resistance significantly decreased only in group C (p=0.011), group D (p=0.009) and group F (p=0.027). CONCLUSION These data suggest that lisinopril/lisinopril + hydrochlorothiazide, losartan/losartan + hydrochlorothiazide and valsartan/valsartan + hydrochlorothiazide alone or in combination with amlodipine are equally effective and well tolerated for the reduction of both systolic and diastolic blood pressure and improve arterial stiffness in patients with essential hypertension.

Abstract
Objective To estimate the prevalence of hypertension and antihypertensive medication recommended among U.S. reproductive-aged women according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline as compared with the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7) guideline and to identify factors associated with newly classified hypertensive women. Methods We analyzed data from the National Health and Nutrition Examination Survey 2005–2014. Hypertension was defined using blood pressure measurements and/or self-reported antihypertensive medication use. Multivariable Poisson regression models with robust error variance were conducted. Results Among 4,575 (weighted n = 40,194,602) non-pregnant women aged 20–44 years, the prevalence of hypertension was 16.5% using the 2017 guideline, and 7.8% based on the JNC7 guideline. Following the 2017 guideline, 8.6% would be recommended for antihypertensive medication, similar to 8.5% according to JNC7 guideline. Following the 2017 guideline, women with older age (35–44 years), obesity, and diabetes were more likely, while Hispanic women were less likely, to be newly classified as hypertensive. Conclusion Among reproductive-aged women, compared to JNC7 guidelines, the prevalence of hypertension increased by 112% following the 2017 guideline, but the percentage of women recommended for antihypertensive medication was similar. Hypertension occurred in about 16.5% of women of reproductive age. The prevalence of hypertension increased by 112% following the new guideline. Several factors associated with newly classified hypertension were identified.

Abstract
The thick ascending limb plays a key role in maintaining water and electrolyte balance. The importance of this segment in regulating blood pressure is evidenced by the effect of loop diuretics or local genetic defects on this parameter. Hormones and factors produced by thick ascending limbs have both autocrine and paracrine effects, which can extend prohypertensive signaling to other structures of the nephron. In this review, we discuss the role of the thick ascending limb in the development of hypertension, not as a sole participant, but one that works within the rich biological context of the renal medulla. We first provide an overview of the basic physiology of the segment and the anatomical considerations necessary to understand its relationship with other renal structures. We explore the physiopathological changes in thick ascending limbs occurring in both genetic and induced animal models of hypertension. We then discuss the racial differences and genetic defects that affect blood pressure in humans through changes in thick ascending limb transport rates. Throughout the text, we scrutinize methodologies and discuss the limitations of research techniques that, when overlooked, can lead investigators to make erroneous conclusions. Thus, in addition to advancing an understanding of the basic mechanisms of physiology, the ultimate goal of this work is to understand our research tools, to make better use of them, and to contextualize research data. Future advances in renal hypertension research will require not only collection of new experimental data, but also integration of our current knowledge.

Abstract
No study investigated whether the presence of specific medical comorbidities is associated with the type of traumatic event, in particular with terrorist attack (TA). In a group of subjects with posttraumatic stress disorder (PTSD), the current study investigated the association between the types of traumatic event (TA vs. other traumatic event [OTE]) and medical comorbidities, controlling for sex and PTSD duration. The Mini International Neuropsychiatric Interview, the Clinician-Administered PTSD Scale, and the Davidson Trauma Scale were administered to 84 subjects diagnosed with PTSD. Thirty-nine were victims of TA and 45 victims of OTE. TA was associated with higher prevalence of neoplasms (β = 2.60, p = 0.02). Females were more protected than males from circulatory system comorbidities (β = 1.47, p = 0.04), while PTSD duration was associated with higher prevalence of such comorbidities (β = 0.005, p = 0.01). Females showed a higher prevalence of neoplasms than males (β = 2.50, p = 0.02). Female sex was protective against metabolic syndrome (β = -1.79, p = 0.02). Patients with PTSD due to TA and female patients should be considered for their higher prevalence of neoplasms, while male patients and those with higher symptom duration should be monitored for circulatory disease and metabolic syndrome. Symptom duration might be associated with circulatory and metabolic disease. Implications for tailored and timely psychopharmacological and psychotherapeutic intervention for PTSD are discussed focusing on these specific medical comorbidities.

Afferent arteriole responsiveness to endothelin receptor activation: does sex matter? Biol Sex Differ 2019; 10:1. [PMID: 30606254 PMCID: PMC6318859 DOI: 10.1186/s13293-018-0218-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2018] [Accepted: 12/17/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND The pathogenesis of hypertension is distinct between men and women. Endothelin-1 (ET-1) is a potential contributor to sex differences in the pathophysiology of hypertension. ET-1 participates in blood pressure regulation through activation of endothelin A (ETA) and endothelin B (ETB) receptors including those in the vasculature. Previous studies demonstrated that sex and sex hormones evoke discrepancies in ET-1-mediated control of vascular tone in different vascular beds. However, little is known about sex- and sex hormone-related differences in ET-1-dependent renal microvascular reactivity. Accordingly, we hypothesized that loss of sex hormones impairs afferent arteriole reactivity to ET-1. METHODS Male and female Sprague Dawley rats were subjected to gonadectomy or sham surgery (n = 6/group). After 3 weeks, kidneys from those rats were prepared for assessment of renal microvascular responses to ET-1 (ETA and ETB agonist, 10-12 to 10-8 M) and sarafotoxin 6c (S6c, ETB agonist, 10-12 to 10-8 M) using the blood-perfused juxtamedullary nephron preparation. RESULTS Control afferent arteriole diameters at 100 mmHg were similar between sham male and female rats averaging 14.6 ± 0.3 and 15.3 ± 0.3 μm, respectively. Gonadectomy had no significant effect on control arteriole diameter. In sham males, ET-1 produced significant concentration-dependent decreases in afferent arteriole diameter, with 10-8 M ET-1 decreasing diameter by 84 ± 1%. ET-1 induced similar concentration-dependent vasoconstrictor responses in sham female rats, with 10-8 M ET-1 decreasing the diameter by 82 ± 1%. The afferent arteriolar vasoconstrictor responses to ET-1 were unchanged by ovariectomy or orchiectomy. Selective ETB receptor activation by S6c induced a concentration-dependent decline in afferent arteriole diameter, with 10-8 M S6c decreasing diameter by 77 ± 3 and 76 ± 3% in sham male and female rats, respectively. Notably, ovariectomy augmented the vasoconstrictor response to S6c (10-12 to 10-9 M), whereas orchiectomy had no significant impact on the responsiveness to ETB receptor activation. CONCLUSION These data demonstrate that sex does not significantly influence afferent arteriole reactivity to ET receptor activation. Gonadectomy potentiated the responsiveness of the afferent arteriole to ETB-induced vasoconstriction in females, but not males, suggesting that female sex hormones influence ETB-mediated vasoconstriction in the renal microcirculation.

J Diabetes Res 2019; 2019:9578391. [PMID: 31093507 PMCID: PMC6481037 DOI: 10.1155/2019/9578391] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 01/15/2019] [Accepted: 02/07/2019] [Indexed: 01/22/2023] Open
Abstract
PURPOSE This cross-sectional study was performed to assess the relationship between simple snoring and metabolic syndrome (MetS). METHODS A total of 5635 participants including 300 healthy volunteers without snoring allegedly were initially included from 2007 to 2016. Polysomnographic variables, anthropometric measurements, and biochemical indicators were collected. The polynomial linear trend test was used to assess the linear trend across snoring intensity for metabolic score, and logistic regression was used to evaluate the odds ratios (ORs) for MetS after controlling for age, sex, obesity, smoking status, and alcohol consumption. RESULTS The final study population consisted of 866 participants. Simple snorers showed more severe metabolic disorders and higher prevalence of MetS than nonsnorers. A significant linear trend was observed between snoring intensity and metabolic score. Simple snoring was significantly associated with increased odds for MetS among all participants (OR = 2.328, 95% CI: 1.340-4.045) and female participants (OR = 2.382, 95% CI: 1.136-4.994) after multivariable adjustment. With regard to MetS components, simple snoring was significantly associated with increased odds for hypertension (OR = 1.730, 95% CI: 1.130-2.650), abdominal obesity (OR = 1.810, 95% CI: 1.063-3.083), and hyper-triglycerides (TG) (OR = 1.814, 95% CI: 1.097-2.998) among all participants, with hypertension (OR = 3.493, 95% CI: 1.748-6.979) among males and with abdominal obesity (OR = 2.306, 95% CI: 1.245-4.270) and hyper-TG (OR = 2.803, 95% CI: 1.146-6.856) among females after multivariable adjustment. CONCLUSIONS After excluding the influence of repeated apnea and hypoxia, simple snoring was still significantly associated with MetS, especially in women. Furthermore, the associations were more obvious for hypertension among males and for abdominal obesity and hyper-TG among females. In addition to OSA, simple snoring also should be valued.
