Psychiatric Manifestations in Early to Middle Stages of Fragile X-Associated Tremor-Ataxia Syndrome (FXTAS).

OBJECTIVE: The purpose of the present study was to assess the psychiatric manifestations of early to middle stages of fragile X-associated tremor-ataxia syndrome (FXTAS) and their relationship with executive function and FMR1 cytosine-guanine-guanine (CGG) repeat numbers across genders. METHODS: Cross-sectional data from 100 participants (62 men, 38 women; mean±SD age=67.11±7.90 years) with FXTAS stage 1, 2, or 3 were analyzed, including demographic information, cognitive measures, psychiatric assessments (Symptom Checklist-90-Revised and Behavioral Dyscontrol Scale-II [BDS-II]), and CGG repeat number. RESULTS: Participants with FXTAS stage 3 exhibited significantly worse psychiatric outcomes compared with participants with either stage 1 or 2, with distinct gender-related differences. Men showed differences in anxiety and hostility between stage 3 and combined stages 1 and 2, whereas women exhibited differences in anxiety, depression, interpersonal sensitivity, obsessive-compulsive symptoms, and somatization, as well as in the Global Severity Index, the Positive Symptom Distress Index, and the Positive Symptom Total. Among male participants, negative correlations were observed between BDS-II total scores and obsessive-compulsive symptoms, as well as between anxiety and CGG repeat number. CONCLUSIONS: These findings suggest that even at early FXTAS stages, patients have significant cognitive and other psychiatric symptoms, with notable gender-specific differences. This study underscores the clinical and prognostic relevance of comorbid psychiatric conditions in FXTAS, highlighting the need for early intervention and targeted support for individuals with relatively mild motor deficits.

Signal mining and gender differences analysis of adverse events in NMIBC treatment with gemcitabine and BCG bladder instillation based on the FAERS database.

OBJECTIVE: To explore safety differences and perform a gender-based analysis of adverse events related to gemcitabine and Bacillus Calmette-Guérin (BCG) vaccine using the U.S. FDA Adverse Event Reporting System (FAERS) database. METHODS: Using the Reporting Odds Ratio (ROR) and Proportional Reporting Ratio (PRR) methods, adverse events associated with gemcitabine and BCG were mined from FAERS database reports spanning from Q1 2004 to Q3 2023. RESULTS: The study extracted 37,855 reports with gemcitabine and 5,455 reports with BCG as the primary suspected drugs. Adverse events were more prevalent in males (male-to-female ratio: gemcitabine 1.10, BCG 4.25). Differences in high-frequency adverse events among the top 20 signals were detected for both drugs. Both drugs affected similar organ systems, including potential pulmonary, ocular, and renal toxicity, with gemcitabine showing a broader range of adverse events. Gender analysis revealed fewer adverse reactions to gemcitabine in females, while males had fewer adverse reactions to BCG. CONCLUSION: Differences in high-frequency adverse events between gemcitabine and BCG, including some not listed on drug labels, were observed. Both drugs affect similar organ systems, with gemcitabine showing a broader range of adverse events. Gender differences in adverse events were notable.

A cross-lagged analysis of the relationship between short video overuse behavior and depression among college students.

Introduction: Watching short videos on mobile phones is currently a very prevalent phenomenon. It has been found in research that excessive use of short videos is closely related to depression. The aim of this study is to investigate the relationship between short video overuse behavior and depression among college students as well as the gender differences that are present in such relationship. Methods: A follow-up measurement was conducted on 331 college students using the Short Video Usage Behavior Scale and the Epidemic Research Center Depression Scale with an interval of 2 months. Results: (1) Correlation analysis revealed a significant positive correlation between short video overuse behavior and depression, whether measured at the same or different time points, repeated measures ANOVA indicates that short video overuse behavior and depression have strong stability within the interval between two measurements. (2) Pre-test short video overuse behavior could significantly and positively predict post-test depression, whereas pre-test depression could not significantly predict post-test short video overuse behavior. (3) The cross-lagged effect between short video overuse behavior and depression showed no gender differences. Discussion: These findings indicate that, for college students, short video overuse behavior may increase the risk of depression, whereas depression cannot induce short video overuse behavior.

The influence of gender on outcomes following transcatheter aortic valve implantation.

Objectives: This study aimed to compare gender-related differences in short- and long-term outcomes after transcatheter aortic valve implantation. Methods: Patients who underwent transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) from September 2017 to December 2022 were enrolled. The primary endpoint was 5-year all-cause mortality. The secondary endpoints were 30-day mortality and the incidence of post-procedural complication. Patients were separated according to gender before statistical analysis. To compare patients with similar baseline characteristics, we performed a propensity matching. Results: A total of 704 patients [females, 361 (51.3%); males, 343 (48.7%)] were enrolled. Compared to women, men had a higher incidence of smoking (40.5% vs. 14.7%, p < 0.001), diabetes (32.9% vs. 25.1%, p < 0.025), peripheral artery disease (35.8% vs. 18.3%, p < 0.001), and previous cardiac surgery (13.7% vs. 7.2%, p = 0.006) and a lower ejection fraction [56.6 (9.3) vs. 59.8 (7.5), p = 0.046]. Female patients were frailer at the time of the procedure [poor mobility rate, 26% vs. 11.7%, p < 0.001; CCI (Charlson comorbidity index) 2.4 (0.67) vs. 2.32 (0.63), p = 0.04]. Despite these different risk profiles, no significant differences were reported in terms of post-procedural outcomes and long-term survival. Propensity score matching resulted in a good match of 204 patients in each group (57.9% of the entire study population). In the matched cohort, men had a significantly higher incidence of new pacemaker implantation compared to women [33 (16.2%) vs. 18 (8.8%)]. The Kaplan-Meier 5-year survival estimate was 82.4% for women and 72.1% for men, p = 0.038. Conclusions: Female gender could be considered as a predictor of better outcomes after TAVI.

Tobacco control policies and the multidimensional context of tobacco use by gender: The case of Türkiye.

OBJECTIVE: This study aims to determine the indicators of tobacco use in Türkiye within a multidimensional context as socio-demographic, physical, behavioural, and psychological as a response to the tobacco control policies. METHODS: The Turkish Health Survey data in 2014 and 2019 are employed within a probit model approach and the differences in tobacco are decomposed use by gender in order to reveal the gender differences. The samples in 2014 (total n = 19,129; males = 8 721, females = 10,408) and 2019 (total n = 17,084; males = 7 784, females = 9300) were restricted to 15-year-old and above. RESULTS: The findings indicate that being in the 30-49 age cohort, having lower education, and being married increase the likelihood of tobacco use. Future policies and campaigns should specifically target the single, pre-obese, employed males who consume alcohol. For females, the gender-specific policies should aim to reduce the prevalence of smoking, especially among separated or widows, obese, and out of the labour force. The contribution of mental health indicators on tobacco use has declined over the 5 years, which could be a result of the supportive free health services in Türkiye. The findings provide evidence for a significant and increasing gender difference in tobacco use in Türkiye along with reporting that the most significant contributors to gender differences in tobacco use are alcohol consumption and education level. CONCLUSION: Even though the Ministry of Health and the government have been implementing anti-tobacco policies, legislations, and campaigns for years, the tobacco use prevalence has remained high and even increased in Türkiye.

Does Medical Curriculum Impact on Empathy? A Longitudinal Study in a Sample of Undergraduate Medical Students.

Empathy in medical students is receiving increasing attention as it is fundamental to build and develop a functional patient-physician relationship. When looking at its determinants, demographic and academic factors seem to concur in shaping empathy in this population. Although data show strong gender differences and changes in empathy throughout medical school, it is not clear the direction of these changes and whether gender and curriculum features modulate them. This longitudinal study examined changes in empathy and explored gender differences throughout the medical school. Four consecutive cohorts of Italian medical students (N = 336) completed the Jefferson Scale of Empathy - Student (JSE-S) and the Interpersonal Reactivity Index (IRI) in their second year of study (before any clinical clerkship and communication skills courses) and fifth year of study (after a 2-year clinical clerkship and communication skills courses). Analysis of variance for repeated-measures revealed that, beyond the effect of gender, JSE-S total score and IRI Perspective Taking increased, whereas IRI Personal Distress and IRI Fantasy significantly decreased throughout medical school. No significant change in IRI Empathic Concern emerged over time. Student's t-tests showed that female students displayed significantly higher mean scores than their male counterparts for all empathy measures in both their second and fifth years of medical training. The findings suggest that the medical curriculum affects self-reported empathy dimensions among undergraduate medical students. Further research is needed to deepen the understanding of the educational factors that promote the changes in empathy levels during medical training.

Retirement preparedness: A study of gender, marital status, and motivation factors by using a theory of planned behavior model.

Although working men and women share common retirement concerns, women encounter unique challenges in securing their retirement. These challenges arise from factors such as part-time work, intermittent work histories, and potential wealth disparities. Marital status also exerts a profound influence on retirement decisions. Marital status significantly impacts their financial security as they approach retirement. This study investigates the intricate relationship between gender, marital status, and theory of planned behavior factors that influence retirement planning among older adults. Utilizing data from the 2014 Health and Retirement Study (HRS) and RAND, the research analyzed 2,657 participants aged 50 to 62, all of whom reported full or part-time employment. Also, the research leveraged the theory of planned behavior to examine motivational factors affecting retirement planning. The study's findings highlight the significant association of gender with expected retirement timing, revealing that married women typically anticipate retiring earlier than both unmarried women and men. In addition, older adults who secure retirement resources tend to retire earlier. It is important to develop tailored policies and initiatives to address the specific retirement challenges women face. It is imperative to develop retirement support systems that consider the gender, marital statuses, and retirement resources of older adults, and to give special attention to those who are vulnerable. This study provides valuable insights into the intricate interplay of gender, marital status, retirement motivation factors and retirement planning among older adults.

Adolescent Peer Relationship Difficulties, Prosociality, and Parental Emotion Socialization: Moderating Roles of Adolescent Gender.

The present study examined longitudinal, transactional associations between youth social adjustment (prosociality, peer relationship difficulties) and parental emotion socialization in early adolescence. Adolescent gender was considered as a potential moderator. Eighty-seven adolescent-parent dyads (50 girls, 37 boys) participated in 8th grade, with follow-up waves in 9th and 10th grade. Adolescents reported their experiences of peer victimization and their parents' emotion socialization responses, and parents reported youth prosocial behavior and peer relation problems. Hierarchical linear modeling results indicated transactional associations between parent supportive/unsupportive responses and adolescent peer relations and prosociality over time, some of which were moderated by adolescent gender. Increases in parental supportive emotion socialization corresponded to decreased experiences of peer victimization over time for girls, but not boys. When peer victimization increased over time, girls reported less parental supportive responses and all adolescents reported receiving more unsupportive responses from parents. For all adolescents, parents' increased supportive responses also corresponded to decreased peer problems and increased prosocial behavior. As prosocial behavior increased, so did parental supportive responses. Increases in parents' unsupportive responses related to decreased prosocial behavior, and increases in adolescent prosocial behavior related to decreases in parents' unsupportive responses. Results suggest that there is mutual influence between parent emotion socialization and adolescent social adjustment. Adolescent girls appear to uniquely benefit from parents' supportive emotional socialization in relation to their experiences of peer victimization. Potential mechanisms and implications are discussed.

Digitalization and job stress: exploring the mediating roles of job and personal aversion risk with gender as a moderator.

Background: This time-lagged study delves into the impact of digitalization on job stress. Digitalization is defined as the incorporation of digital technologies into various aspects of work life, fundamentally transforming processes, interactions, and decision-making. Aim: The present research focuses on the mediating roles of job-related risk and personal risk, and the moderating effect of gender. We hypothesized that employees' aversion to risks, both in their professional and personal facets, mediates the relationship between the rapid digitalization of their work environment and the resultant job stress. Regarding gender as a moderator, recent research suggests that gender can influence the experience of workplace stress, with women often experiencing higher levels of stress than men in certain situations. This indicates that gender might also moderate the relationship between digital living, risk perception, and job-related stress. This approach allows for an examination of the ways in which digital technology adoption influences workplace stress, considering the temporally spaced data. Methods: Conducted over three waves of data collection among 795 Chinese employees, the research utilizes Hayes's Model 8, adept at revealing the dynamics of digitalization's influence in the workplace and its effects on individual well-being. Results: The study corroborates Hypothesis 1 by establishing a significant, albeit less pronounced, relationship between digital living and job stress. The findings also support Hypothesis 2 by demonstrating that both job risk and personal risk mediate this relationship. The study's results also validate Hypothesis 3, indicating that gender moderates the relationship between digital living, job risk, personal risk, and job stress. Finally, the significant interaction effects found in the study, particularly the stronger conditional negative effect of digital living on perceptions of job and personal risks for males, despite the absence of statistical significance failed to support Hypothesis 4. Implications: This study sheds light on the dynamics of job stress in the context of a digitalizing work environment. The results have important implications for designing workplace strategies and interventions that are sensitive to risk perceptions and gender differences in the digital era.

Parental Mental Health, Gender, and Lifestyle Effects on Post-Pandemic Child and Adolescent Psychosocial Problems: A Cross-Sectional Survey in Northern Italy.

BACKGROUND: The exacerbation of psychosocial problems among children and adolescents during the coronavirus disease 2019 (COVID-19) pandemic necessitates an assessment of the long-term mental health impact of pandemic interventions. Focusing on both pandemic-related factors and demographic variables, such as gender and daily habits, an analysis was conducted to understand how these elements continue to affect young populations in the post-pandemic era. METHODS: In April 2023, a comprehensive online survey was administered to families in South Tyrol, Italy, with children aged 7-19 years, to ensure age and gender representation. The survey included parent ratings and adolescent (11-19 years) self-reports using standardized instruments to measure the symptoms of mental health problems (Strengths and Difficulties Questionnaire, SDQ), anxiety (Screen for Child Anxiety Related Emotional Disorders, SCARED), and depression (Patient Health Questionnaire-2, PHQ-2). Statistical analyses included descriptive statistics, chi-square tests, and unadjusted odds ratios (ORs). RESULTS: Of the 4525 valid responses, 1831 were self-reported by adolescents. Notable gender differences in mental health outcomes were identified, along with significant demographic predictors, such as age, single parenthood, parental mental health problems, and immigrant background. Negative effects were associated with reduced family climate and increased screen time, whereas physical activity showed beneficial effects. Proxy reports overestimated adolescents' mental health problems, whereas self-reports tended to underestimate them. CONCLUSIONS: Persistent mental health problems and gender disparities highlight the need for a public health approach. This should include accessible support services, resilience building, targeted support for vulnerable families and gender-specific interventions.

Gender Differences in Survival after Coronary Artery Bypass Grafting-13-Year Results from KROK Registry.

The influence of gender on both early and long-term outcomes of coronary artery bypass grafting (CABG) is not clearly defined. Objectives: This study aimed to assess the impact of gender on early and long-term mortality after CABG using data from the KROK Registry. Methods: All 133,973 adult patients who underwent CABG in Poland between 1 January 2009 and 31 December 2019 were included in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry). The study enrolled 90,541 patients: 68,401 men (75.55%) and 22,140 women (24.45%) who met the inclusion criteria. Then, 30-day mortality, 1-year mortality, and long-term mortality rates were compared. Results: Advanced age, higher Canadian Cardiovascular Society (CCS) and New York Heart Association (NYHA) grade, diabetes, hypercholesterolemia, arterial hypertension, body mass index BMI > 35 kg/m2, and renal failure, before the propensity matching, were more frequently observed in women. Women more frequently underwent urgent surgery, including single and double graft surgery, and off-pump CABG (OPCAB) (p < 0.001). In propensity-matched groups, early mortality (30 days) was significantly higher in women (3.4% versus 2.8%, p < 0.001). The annual mortality remained higher in this group (6.6% versus 6.0%, p = 0.025). However, long-term mortality differed significantly between the groups and was higher in the male group (33.0% men versus 28.8% women, p < 0.001). Conclusions: There are no apparent differences in long-term mortality between the two sexes in the entire population. In propensity-matched patients, early mortality was lower for men, but the long-term survival was found to be better in women.

Sex-Gender Differences Are Completely Neglected in Treatments for Neuropathic Pain.

As sex-gender differences have been described in the responses of patients to certain medications, we hypothesized that the responses to medications recommended for neuropathic pain may differ between men and women. We conducted a literature review to identify articles reporting potential sex-gender differences in the efficacy and safety of these medications. Only a limited number of studies investigated potential sex-gender differences. Our results show that women seem to achieve higher blood concentrations than men during treatment with amitriptyline, nortriptyline, duloxetine, venlafaxine, and pregabalin. Compared to men, higher rates of women develop side effects during treatment with gabapentin, lidocaine, and tramadol. Globally, the sex-gender differences would suggest initially administering smaller doses of these medications to women with neuropathic pain compared to those administered to men. However, most of these differences have been revealed by studies focused on the treatment of other diseases (e.g., depression). Studies focused on neuropathic pain have overlooked potential sex-gender differences in patient responses to medications. Despite the fact that up to 60% of patients with neuropathic pain fail to achieve an adequate response to medications, the potential role of sex-gender differences in the efficacy and safety of pharmacotherapy has not adequately been investigated. Targeted studies should be implemented to facilitate personalized treatments for neuropathic pain.

Exploring the relationship between binge eating and differentiation of self: the mediating role of emotional distress and work stress.

Binge Eating Disorder (BED) is a prevalent eating disorder outlined in the DSM-5. Emotional distress (including stress, anxiety, and depression) stands out as a critical risk factor for developing eating disorders, and specifically BED. Recent studies have identified differentiation of self- a family pattern involving the ability to balance emotions and cognitions, as well as intimacy and autonomy-as a factor that exacerbates emotional distress. This relationship highlights the importance of addressing both emotional distress and family dynamics in understanding BED. While associations have been found between work-related factors and family dynamics with emotional distress, there has been limited investigation into the specific risk factors that are uniquely linked to BED. It was hypothesized that differentiation of self would relate to BED symptoms through the mediation of emotional distress and work stress. A systematic sampling method was applied to select a total of 275 participants for this study, with 60% women and 40% men (aged 20-45, M = 32.71, SD = 7.50). The findings suggest that low differentiation of self may increase vulnerability to BED symptoms by increasing susceptibility to emotional distress, including stress in the workplace. In addition, the analyses indicated that women reported higher levels of BED symptoms, while men reported higher levels of differentiation of self. The study sheds light on the contribution of unregulated family and emotional patterns to BED, providing valuable insights for organizations seeking to promote healthier work environments.

Association between social isolation and diversity in food intake by gender in community-dwelling older adults: A cross-sectional study.

AIM: Few studies have investigated the relationship between low dietary variety and clearly defined social isolation by gender. This study explored the association between dietary variety and social isolation, classified by operational definition, separately by gender in community-dwelling older adults. METHODS: This cross-sectional study recruited respondents via mail. A total of 4798 participants aged ≥65 years participated in the on-site assessment. Social isolation was assessed by "lack of conversation," "lack of passive support," "lack of offering support," and "lack of social participation." Dietary variety was evaluated using the Dietary Variety Score (DVS). RESULTS: The participants' median age was 73 (interquartile range 25-75: 69-77) years, and 2147 (44.7%) were male. After adjusting for covariates, with regard to male participants, a lack of offering support (ß = -0.051, P = 0.019) and a lack of social participation (ß = -0.089, P < 0.001) were associated with a low DVS. For female participants, only a lack of social participation was related to a low DVS (ß = -0.067, P < 0.001). A lack of conversation and passive support were not associated with a low DVS for both genders (P >0.05). CONCLUSION: The results indicate that encouraging social participation, regardless of gender, as well as preventing a lack of offering support for others among men, may contribute to improving individuals' DVS.

A short mindfulness induction might increase women's mental rotation performance.

The study aimed to investigate the effects of an embodied mindfulness treatment on chronometric mental rotation. Forty-four women and 47 men participated and were randomly divided into two groups: a mindfulness induction group and a control group. They completed two sets of 150 mental rotation tasks with cube figures each. Subjective cognitive effort (measured after each block), reaction time, and accuracy were analyzed using linear mixed models with the factors of time, mindfulness, angular disparity, and gender. The significant finding was a three-way interaction between pre-post testing, mindfulness, and gender for reaction times. This interaction suggests that women might benefit more from the mindfulness induction, while men may benefit more from the control condition. The analysis of subjective cognitive effort indicates that women and men perceive the same cognitive effort when solving cube-figure tasks.

Gender-Specific Pathways in Violent Crime: Investigating the Role of Demographic and Mental Health Factors Using Mixed Graphical Models and Bayesian Networks.

This research aims to uncover gender-specific relationships and pathways that contribute to the perpetration of violent crimes, using sophisticated analytical tools to analyze the complex interactions between various factors. Employing Mixed Graphical Models and Bayesian networks, the study analyzes a sample of 1,254 prisoners (61.64% males and 38.36% females) to investigate the relationships among demographic factors, mental health issues, and violent crime. The study utilizes comprehensive measures, including the Beck Depression Inventory, Beck Anxiety Inventory, and Childhood Trauma Questionnaire, to assess participants' mental health status.Key findings reveal significant gender differences in the pathways to violent crime. For males, incomplete parental marriages strongly correlate with criminal behavior severity, while marriage status emerges as a significant factor, with married males less likely to commit violent crimes. In contrast, these relationships are not significant for females. Bayesian network analysis indicates that living in urban areas differently influences education and emotional expression across genders, emphasizing the importance of contextual factors. The study highlights the need for gender-specific considerations in criminal justice policies and interventions. It underscores the complex interplay of demographic and mental health factors in influencing violent crime pathways, providing insights for developing more effective prevention strategies. Despite its cross-sectional design and reliance on self-reported data, the research significantly contributes to understanding the gendered dimensions of criminal behavior.

The impact of school closures during the COVID-19 pandemic on reading fluency among second grade students: socioeconomic and gender perspectives.

Introduction: The acquisition of reading skills is a crucial milestone in early education, with formal instruction and practice playing pivotal roles. The outbreak of COVID-19 led to widespread school closures and a shift to remote learning. Methods: This study aimed to investigate the effects of school closures on reading acquisition and fluency among a large sample of second-grade children, considering socioeconomic status (SES) and gender differences. In 2019, a cohort of 2228 second-grade students from 34 schools was assessed for word reading fluency and comprehension. In 2020, during the pandemic, 765 students from a subsample of 20 original schools were re-evaluated using the same measures. The study also collected school-related data. Results: The findings from the entire sample indicated no significant differences in fluency and comprehension scores between children in the second grade in 2019 and 2020. However, a significant interaction emerged when analyzing low SES versus high SES children. Children from low SES backgrounds exhibited notably lower reading scores after a year of remote learning due to the COVID-19 outbreak. Moreover, the disparity in reading scores between low SES and high SES children nearly doubled in 2020. Gender differences were also detected. Discussion: These results underscore the impact of remote learning during the COVID-19 crisis on exacerbating gaps in reading fluency and comprehension between children from high and low SES backgrounds. The implications of these findings highlight the critical role of in-person schooling and targeted support for disadvantaged students, especially during pivotal stages of reading development.

Pulmonary embolism: incidence and outcomes in a twelve-year historical series, in Tuscany - Italy (2010-2021).

Background: Pulmonary embolism poses a global health concern. Administrative databases serve as valuable sources for broad epidemiological studies on the prevalence and incidence of major diagnoses or diseases. The primary scope is to provide up-to-date insights into Pulmonary Embolism incidence trends, examining shifts in management and outcomes. Design: This retrospective observational study examines a 12-year dataset from hospitals in the Tuscany Region, covering the first two years of the Covid-19 pandemic. Methods: Administrative data from residents aged 18 and older discharged from hospital between 2010 and 2021 were used for the analysis. Results: Hospitalized pulmonary embolism incidence slightly declined from 2010 to 2019 (64.7 to 60.9 x 100,000; p=0.152). Males under 75 showed a higher incidence rate, while females had higher incidence rates in older age groups. In-hospital and 30-day mortality decreased from 2010 to 2019 (p=0.001 and 0.020 respectively). In 2020, 30-day mortality increased (12.4% vs 10.1%, p=0.029), while in-hospital mortality remained stable. One-year mortality was stable from 2010-2019 but increased in 2020 (32.6% vs 29.4%, p=0.037). Considering the multivariable model, one-year mortality is significantly associated with sex, age, and comorbidities. Conclusions: Our study shows that Pulmonary Embolism persists as a relevant burden in Tuscany region, but with improvements in management over the past decade and a decisive change in pharmacological treatment. Gender-related differences emerge, highlighting the need for a gender-specific healthcare approach.

Sex Differences in the Relationship Between Self-Reporting of Snoring and Cardiovascular Risk:An Analysis of NHANES.

Background: Identifying risk factors for cardiovascular disease (CVD) is critical for effective prevention and management. While classic CVD risk factors have been extensively studied, there is a scarcity of research on the association between snoring and CVD risk, particularly in the context of sex differences. Methods: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted between 2015 and 2020. Participants were initially categorized based on the severity of snoring or the presence of snoring.Within the snoring group, they were further classified by sex. Analysis was carried out using multivariate logistic regression. Results: Our study included 12,681 participants aged 18 years or older. When compared to the non-snoring group, individuals in the moderate snoring group had a higher odds ratio (OR) of 1.418 (95% CI 1.083 to 1.857, p = 0.011), while those in the severe snoring group had a higher OR of 1.882 (95% CI 1.468 to 2.409, p < 0.001). In the snoring group, individuals were further categorized by gender: 4527 males and 4131 females. Importantly, male patients showed a higher OR for atrial fibrillation (4.945, 95% CI 1.187 to 20.598, p = 0.028) compared to females. Additionally, male patients had a higher OR for coronary heart disease (2.002, 95% CI 1.152 to 3.479, p = 0.014) compared to females. Conclusion: Sex plays a significant role in the relationship between snoring and CVD risk. Males with snoring have a higher risk of developing CVD compared to females. In particular, male snorers are nearly five times more likely to develop atrial fibrillation and about twice as likely to experience coronary artery disease in comparison to female snorers. It is recommended that healthcare providers and public health officials prioritize cardiovascular risk assessments for male individuals who exhibit symptoms of snoring.

Greater sensitivity of the circadian system of women to bright light, but not dim-to-moderate light.

Women typically sleep and wake earlier than men and have been shown to have earlier circadian timing relative to the light/dark cycle that synchronizes the clock. A potential mechanism for earlier timing in women is an altered response of the circadian system to evening light. We characterized individual-level dose-response curves for light-induced melatonin suppression using a within-subjects protocol. Fifty-six participants (29 women, 27 men; aged 18-30 years) were exposed to a range of light illuminances (10, 30, 50, 100, 200, 400, and 2000 lux) using melatonin suppression relative to a dim control (<1 lux) as a marker of light sensitivity. Women were free from hormonal contraception. To examine the potential influence of sex hormones, estradiol and progesterone was examined in women and testosterone was examined in a subset of men. Menstrual phase was monitored using self-reports and estradiol and progesterone levels. Women exhibited significantly greater melatonin suppression than men under the 400-lux and 2000-lux conditions, but not under lower light conditions (10-200 lux). Light sensitivity did not differ by menstrual phase, nor was it associated with levels of estradiol, progesterone, or testosterone, suggesting the sex differences in light sensitivity were not acutely driven by circulating levels of sex hormones. These results suggest that sex differences in circadian timing are not due to differences in the response to dim/moderate light exposures typically experienced in the evening. The finding of increased bright light sensitivity in women suggests that sex differences in circadian timing could plausibly instead be driven by a greater sensitivity to phase-advancing effects of bright morning light.
