Inequality on the frontline: A multi-country study on gender differences in mental health among healthcare workers during the COVID-19 pandemic.

Healthcare workers (HCWs) were at increased risk for mental health problems during the COVID-19 pandemic, with prior data suggesting women may be particularly vulnerable. Our global mental health study aimed to examine factors associated with gender differences in psychological distress and depressive symptoms among HCWs during COVID-19. Across 22 countries in South America, Europe, Asia and Africa, 32,410 HCWs participated in the COVID-19 HEalth caRe wOrkErS (HEROES) study between March 2020 and February 2021. They completed the General Health Questionnaire-12, the Patient Health Questionnaire-9 and questions about pandemic-relevant exposures. Consistently across countries, women reported elevated mental health problems compared to men. Women also reported increased COVID-19-relevant stressors, including insufficient personal protective equipment and less support from colleagues, while men reported increased contact with COVID-19 patients. At the country level, HCWs in countries with higher gender inequality reported less mental health problems. Higher COVID-19 mortality rates were associated with increased psychological distress merely among women. Our findings suggest that among HCWs, women may have been disproportionately exposed to COVID-19-relevant stressors at the individual and country level. This highlights the importance of considering gender in emergency response efforts to safeguard women's well-being and ensure healthcare system preparedness during future public health crises.

The Relationship Between Overparenting and Social Avoidance Among Emerging Adults: Mediating Role of Peer Attachment and Gender Differences.

Purpose: We aim to explore the relationship between overparenting and social avoidance among emerging adults, and the mediating effects of peer attachment and gender differences. Participants and Methods: A total of 1161 Chinese college students completed the questionnaire. The structural equation model was established to validate the main effect model and the mediation model. Results: The results found that both paternal and maternal overparenting positively predicted social avoidance among emerging adults. Both attachment avoidance and attachment anxiety played a significant mediating role in the relationship between paternal overparenting and social avoidance. Attachment anxiety played a significant mediating role in the relationship between maternal overparenting and social avoidance, while, the mediating effect of attachment avoidance was not significant. In addition, gender differences were found in the mediating effects of peer attachment. The mediating effect of attachment anxiety in males' families had an opposite-gender matching effect, while in females' families, the mediating effect of attachment avoidance had an opposite-gender matching effect. Conclusion: This study contributes to the understanding of the effects of overparenting on emerging adults, enriching empirical research in related fields.

Age and sex mediated effects of estrogen and Β3-adrenergic receptor on cardiovascular pathophysiology.

Sex differences are consistently identified in determining the prevalence, manifestation, and response to therapies in several systemic disorders, including those affecting the cardiovascular (CV), skeletal muscle, and nervous system. Interestingly, such differences are often more noticeable as we age. For example, premenopausal women experience a lower risk of CV disease than men of the same age. While at an advanced age, with menopause, the risk of cardiovascular diseases and adverse outcomes increases exponentially in women, exceeding that of men. However, this effect appears to be reversed in diseases such as pulmonary hypertension, where women are up to seven times more likely than men to develop an idiopathic form of the disease with symptoms developing ten years earlier than their male counterparts. Explaining this is a complex question. However, several factors and mechanisms have been identified in recent decades, including a role for sex hormones, particularly estrogens and their related receptors. Furthermore, an emerging role in these sex differences has also been suggested for ß-adrenergic receptors (ßARs), which are essential regulators of mammalian physiology. It has in fact been shown that ßARs interact with estrogen receptors (ER), providing further demonstration of their involvement in determining sexual differences. Based on these premises, this review article focused on the ß3AR subtype, which shows important activities in adipose tissue but with new and interesting roles in regulating the function of cardiomyocytes and vascular cells. In detail, we examined how ß3AR and ER signaling are intertwined and whether there would be sex- and age-dependent specific effects of these receptor systems.

Injury Patterns and Gender in Italy.

Introduction: Globally, injuries pose significant public health challenges, with road traffic accidents in particular being responsible for considerable morbidity, mortality, and economic distress. Italy has been significantly impacted due to its high population density and frequency of road traffic and domestic incidents. Method: This study set out to investigate the incidence of self-reported road traffic and home and leisure accidents in the Italian general population. A particular emphasis was placed on exploring possible gender differences across varying age groups. The data was obtained from the European Health Interview Survey and a representative sample of the Italian population was analyzed. Results: The analysis revealed that regardless of age, women experienced a reduced risk of road traffic accidents compared to men. However, gender disparities in home-leisure accidents were observed to be age-dependent. Women under the age of 25 exhibited a lower likelihood of home-leisure accidents and serious accidents necessitating hospital admission in comparison to their male counterparts. In contrast, women aged 65 and above had an increased likelihood of home-leisure accidents as opposed to men in the same age category. Conclusions: The findings of this study highlight the importance of considering age and gender as significant factors in the occurrence of different types of accidents, offering insight into how injury rates vary between these demographic groups within Italy.

The comorbid network characteristics of anxiety and depressive symptoms among Chinese college freshmen.

BACKGROUND: This study aimed to investigate the interplay between anxiety and depressive symptoms in Chinese college freshmen using the causal system perspective (CSP), which differs from the traditional common cause perspective (CCP) by providing an alternative explanation by attributing comorbidity to direct interactions among symptoms. METHODS: A convenience sample of 2,082 Chinese college freshmen (39.51% male, Mage = 18.61) from a normal university completed the Generalized Anxiety Disorder 7-Item Scale (GAD-7) and the Patient Health Questionnaire (PHQ-9). Network analysis was conducted and evaluated as to centrality, stability, node predictability, and bridging features. Moreover, the moderated network model (MNM) was utilized to detect the moderation effects of gender in the comorbidity network. RESULTS: The network of anxiety and depressive symptoms exhibited stability, characterized by the core symptoms of "restlessness", "lack of energy", and "excessive worry about control", as well as the bridging symptoms of "fearfulness", "sad mood", and "irritability". Notably, the nodes representing "uncontrollable worry" and "difficulty in relaxation" demonstrated the highest predictive power. Gender did not exert any moderating effects on the anxiety and depressive symptom network. CONCLUSION: These results reinforce that certain anxiety or depressive symptoms are more central than others, and thus play a more vital role in the comorbid network. These findings highlight underlying potential targeting symptoms to consider in future interventions.

Do emergency medical dispatchers choose the same response to serious injury in men and women - a qualitative study.

BACKGROUND: Recent research has indicated that sex is an important determinant of emergency medical response in patients with possible serious injuries. Men were found to receive more advanced prehospital treatment and more helicopter transportation and trauma centre destinations and were more often received by an activated trauma team, even when adjusted for injury mechanism. Emergency medical dispatchers choose initial resources when serious injury is suspected after a call to the emergency medical communication centre. This study aimed to assess how dispatchers evaluate primary responses in trauma victims, with a special focus on the sex of the victim. METHODS: Emergency medical dispatchers were interviewed using focus groups and a semistructured interview guide developed specifically for this study. Two vignettes describing typical and realistic injury scenarios were discussed. Verbatim transcripts of the conversations were analysed via systematic text condensation. The findings were reported in accordance with the Consolidated Criteria for Reporting Qualitative Studies (COREQ) checklist. RESULTS: The analysis resulted in the main category "Tailoring the right response to the patient", supported by three categories "Get an overview of location and scene safety", "Patient condition" and "Injury mechanism and special concerns". The informants consistently maintained that sex was not a relevant variable when deciding emergency medical response during dispatch and claimed that they rarely knew the sex of the patient before a response was implemented. Some of the participants also raised the question of whether the Norwegian trauma criteria reliably detect serious injury in women. CONCLUSIONS: The results indicate that the emergency medical response is largely based on the national trauma criteria and that sex is of little or no importance during dispatch. The observed sex differences in the emergency medical response seems to be caused by other factors during the emergency medical response phase.

Eating disorders and social media use among college students in Japan and China: a brief cross-sectional survey.

BACKGROUND: In recent years, new forms of media-social networking services (SNS)-such as Facebook and Sina Weibo have spread rapidly. Greater SNS use has been associated with greater body dissatisfaction, which in turn, is related to greater eating disorder (ED) symptom severity. In this study, we (1) investigated the relationships between ED tendencies, SNS use intensity, and body esteem and (2) examined the mediating role of body esteem in the relationship between SNS use intensity and ED tendencies among Japanese and Chinese students. METHODS: A total of 564 Japanese and Chinese college students aged 18-22 years were surveyed on their age and BMI, including self-filling questions from the Japanese and Chinese versions of the Eating Attitudes Test (EAT-26), SNS Intensity Scale, Body Esteem Scale for Adolescents and Adults (BESAA), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) scale. RESULTS: The proportion of students with a score of ≥ 20 on the EAT-26 was 15.8% (Japanese, 14.7%; Chinese, 17.0%). The number of participants with scores ≥ 20 on the EAT-26 was significantly higher than ever before, both in Japan and China. Chinese students reported greater body esteem than Japanese students, as well as a stronger association of SNS use intensity with body esteem. Among Japanese students, EAT-26 scores were unrelated to SNS Intensity Scale scores but had a weak negative correlation with BESAA scores; therefore, body esteem did not mediate the relationship between SNS use intensity and ED tendencies. Among Chinese students, scores on the SNS Intensity Scale and BESAA had a weak correlation with EAT-26 scores, and SNS use intensity reduced ED tendencies through greater body esteem. CONCLUSIONS: It is important to consider the way users engage with SNS, in addition to the SNS use intensity. Improving body esteem may reduce the risk of ED. Furthermore, it is necessary to include men in the discussion on ED in the future.

We investigated the relationships between eating disorder (ED) tendencies, social networking service (SNS) use intensity, and body esteem among Japanese and Chinese students, and compared the findings. We surveyed 564 Japanese and Chinese students regarding basic demographic information, ED tendencies, SNS use, body esteem, depression, and anxiety. The results showed that the number of participants with scores ≥ 20 on the Eating Attitudes Test was significantly higher than ever before, both in Japan and China. In Japanese students, body esteem affected ED tendencies, while SNS use intensity did not. In Chinese students, SNS use intensity reduced ED tendencies through greater body esteem. There were no gender differences in Eating Attitudes Test scores among Japanese students. This study provides evidence for the relationship between ED tendencies, SNS use, and body esteem in Asian countries.

Gender differences in the impact of anatomical factors on non-contact anterior cruciate ligament injuries: a magnetic resonance study.

PURPOSE: To identify MRI-detected anatomical risk factors for non-contact anterior cruciate ligament (ACL) injuries across genders. METHODS: A retrospective analysis was performed on 141 ACL-reconstructed patients (35 females, 106 males) and 142 controls (37 females, 105 males) from January 2020 to April 2022. Inclusion criteria were primary non-contact ACL injuries. The tibial plateau slope, lateral femoral condyle index, Insall-Salvati index, and patellar tendon angle were measured, using binary logistic regression for gender-specific risk evaluation. RESULTS: Increased lateral tibial plateau slope, reduced intercondylar notch width index, lateral femoral condyle index, and patellar tendon angle correlated with ACL injuries in both genders. The Insall-Salvati index was a significant risk factor in females but not in males. CONCLUSION: This study identifies the lateral tibial plateau slope, notch width index, lateral femoral condyle index, and patellar tendon angle at near-extension as risk factors for ACL injuries in both genders, with the Insall-Salvati index also implicated in females.

Association Between Self-Construals, Social Pain Sensitivity, and Gender in Young Adults.

We experience pain in response to negative, unwanted social interaction with others (e.g., social rejection), and this type of pain is termed as social pain in the recent literature. While sensitivity to social pain may be beneficial to increase a chance for survival, social pain sensitivity could also be detrimental to elevate the risk of various health issues. Such opposing natures of social pain sensitivity warrants research to better identify factors that are linked to social pain sensitivity. Self-construals show perspectives on how to view oneself in relations to others, characterized as independent and interdependent self-construals, and may be linked to social pain sensitivity. Additionally, pervious data have indicated gender differences in social pain sensitivity, but it is unclear if self-construals explain gender differences in social pain sensitivity. Therefore, this study examined if self-construals were associated with social pain sensitivity, and gender differences in social pain sensitivity were accounted for by self-construals. The participants were 148 college students who completed several self-report questionnaires to evaluate self-construals and social pain sensitivity. The results indicated that interdependent tendency, which showed higher interdependent self-construal than independent self-construal, was associated with social pain sensitivity. While gender differences in social pain sensitivity were confirmed, gender differences in social pain sensitivity were not accounted for by interdependent tendency. The results suggest that interdependent tendency is associated with social pain sensitivity, but is not involved in gender differences in social pain sensitivity.

Treating sex and gender differences as a continuous variable can improve precision cancer treatments.

BACKGROUND: The significant sex and gender differences that exist in cancer mechanisms, incidence, and survival, have yet to impact clinical practice. One barrier to translation is that cancer phenotypes cannot be segregated into distinct male versus female categories. Instead, within this convenient but contrived dichotomy, male and female cancer phenotypes are highly overlapping and vary between female- and male- skewed extremes. Thus, sex and gender-specific treatments are unrealistic, and our translational goal should be adaptation of treatment to the variable effects of sex and gender on targetable pathways. METHODS: To overcome this obstacle, we profiled the similarities in 8370 transcriptomes of 26 different adult and 4 different pediatric cancer types. We calculated the posterior probabilities of predicting patient sex and gender based on the observed sexes of similar samples in this map of transcriptome similarity. RESULTS: Transcriptomic index (TI) values were derived from posterior probabilities and allowed us to identify poles with local enrichments for male or female transcriptomes. TI supported deconvolution of transcriptomes into measures of patient-specific activity in sex and gender-biased, targetable pathways. It identified sex and gender-skewed extremes in mechanistic phenotypes like cell cycle signaling and immunity, and precisely positioned each patient's whole transcriptome on an axis of continuously varying sex and gender phenotypes. CONCLUSIONS: Cancer type, patient sex and gender, and TI value provides a novel and patient- specific mechanistic identifier that can be used for realistic sex and gender-adaptations of precision cancer treatment planning.

Some efforts to improve cancer therapy involve the idea of personalizing treatments to who a patient is and how their cancer operates. Personalizing treatment can involve straighforward features like a patient's age, family cancer history, personal disease and surgical histories, as well as more complex features like analysis of their specific cancer's mechanisms of growth and spread throughout the body. One glaring omission in common personalization schemes is the sex and gender of the patient. While patient sex and gender is known to substantially affect cancer rates and response to treatment, we do not yet use this information in treatment planning. There are multiple reasons for this but among them is that we tend to think about sex and gender as an either/or categorization. You are either a male/man or a female/woman. This is not accurate as there are many variables that contribute to who an individual is as a male/man or female/woman. This variability is a challenge to incorporating these features into personalized treatment planning. Here, we have developed a method to address this challenge. It is our great hope that this will enable the use of this critically important element of personalization in cancer treatment planning and improve survival rates for all patients.

Training in the implementation of sex and gender research policies: an evaluation of publicly available online courses.

BACKGROUND: Recently implemented research policies requiring the inclusion of females and males have created an urgent need for effective training in how to account for sex, and in some cases gender, in biomedical studies. METHODS: Here, we evaluated three sets of publicly available online training materials on this topic: (1) Integrating Sex & Gender in Health Research from the Canadian Institutes of Health Research (CIHR); (2) Sex as a Biological Variable: A Primer from the United States National Institutes of Health (NIH); and (3) The Sex and Gender Dimension in Biomedical Research, developed as part of "Leading Innovative measures to reach gender Balance in Research Activities" (LIBRA) from the European Commission. We reviewed each course with respect to their coverage of (1) What is required by the policy; (2) Rationale for the policy; (3) Handling of the concepts "sex" and "gender;" (4) Research design and analysis; and (5) Interpreting and reporting data. RESULTS: All three courses discussed the importance of including males and females to better generalize results, discover potential sex differences, and tailor treatments to men and women. The entangled nature of sex and gender, operationalization of sex, and potential downsides of focusing on sex more than other sources of variation were minimally discussed. Notably, all three courses explicitly endorsed invalid analytical approaches that produce bias toward false positive discoveries of difference. CONCLUSIONS: Our analysis suggests a need for revised or new training materials that incorporate four major topics: precise operationalization of sex, potential risks of over-emphasis on sex as a category, recognition of gender and sex as complex and entangled, and rigorous study design and data analysis.

Recently implemented research policies requiring the inclusion of females and males have created an urgent need for effective training in how to account for sex, and in some cases gender, in biomedical studies. We evaluated three publicly available online trainings on this topic: (1) Integrating Sex & Gender in Health Research from the Canadian Institutes of Health Research; (2) Sex as a Biological Variable: A Primer from the United States National Institutes of Health; and (3) The Sex and Gender Dimension in Biomedical Research, developed as part of "Leading Innovative Measures to Reach Gender Balance in Research Activities (LIBRA)" from the European Commission.

All three discussed the importance of including males and females to better generalize results, discover potential sex differences, and tailor treatments to men and women. The interconnectedness of sex and gender, how to operationalize sex, and potential downsides of focusing on sex more than other sources of variation were minimally discussed. Notably, all three courses explicitly endorsed invalid analytical approaches that lead to incorrect findings of differences. Our analysis suggests a need for revised or new training materials that cover four major topics: precise operationalization of sex, attention to potential risks of over-emphasizing sex, consideration of gender and sex as complex and intertwined, and rigorous study design and data analysis.

Gender differences in relation to stigmatization and depressive symptoms after burns.

OBJECTIVES: The aim of this study was to investigate the moderating role of gender in the relationship between burn severity, perceived stigmatization and depressive symptoms at multiple time points postburn. MATERIALS AND METHODS: This multi-center study included data from two cohorts. Cohort 1 consisted of 215 burn survivors, participating in a longitudinal study with measures at 3 and 12 months postburn. Cohort 2 consisted of 180 burn survivors cross-sectionally assessed at 5 - 7 years postburn. Both cohorts completed self-reported measures of perceived stigmatization and depressive symptoms. The number of acute surgeries (i.e., no surgery, 1 surgery or 2 or more surgeries) was used as indicator of burn severity. Relations between number of surgeries, depressive symptoms, and perceived stigmatization, including possible indirect effects, were evaluated with gender-specific path models. RESULTS: In both men and women, number of surgical operations was related to higher levels of depressive symptoms and perceived stigmatization at 3 months after burn. In women, number of operations was still directly related to both constructs at 12 months after burn, which was cross-sectionally confirmed in the 5-7 years after burn cohort. In men, from 3 to 12 months after burn, depressive symptoms and perceived stigmatization were bidirectionally related, and, through these effects, number of surgeries was indirectly related to both outcomes. In the cross-sectional 5-7 years after burn cohort, number of operations was related to stigma but not to depressive symptoms of men. CONCLUSION: Number of operations had a different effect on psychosocial adaptation of male and female burn survivors. In women, a persistent direct link from number of operations to both depressive symptoms and perceived stigmatization was found over time. In men, the effect of number of operations was most evident in the short-term, after which perceived stigmatization and depressive symptoms became interrelated. This indicates that burn severity remains a factor of significance in psychological adjustment in women, whereas in men, this significance seems to decrease over time.

Unmasking Distorted Reflections: Exploring Body Image, Alcohol, and Drug Use in Nighttime Entertainment Districts.

Background: Violence within nighttime entertainment districts (NEDs) has been blamed on problematic masculinity and has predominantly been attributed to excessive alcohol intake and steroid use in men. In this report we conducted two studies to: (1) ascertain whether researchers could act as third-party raters of body weight and muscle mass in NED patrons; and (2) to examine the relationship between body self-image, inebriation, alcohol preloading behaviors and drug use in the NEDs. Methods: Study 1 employed an observational approach to establish inter-rater reliability for ratings of muscle mass and weight. In Study 2 data (n = 2,745) were collected through breathalyzing and questionnaires to examine individuals' self-image and drinking and drug-taking behaviors. Results: Participants' self-ratings of muscle and weight significantly differed from researchers' ratings, with males perceiving themselves as less muscular and females perceiving themselves as heavier. Perceived weight and muscle size did not relate to alcohol levels, but an interaction was found for female steroid users who perceived themselves as less muscular. Conclusions: Findings indicated a distortion in participants' perceived body image, with a desire for muscularity among both males and females. These results underscore the complex interplay between self-perception, societal ideals, and drug use in young NED patrons.

Gender Differences in Trends in Incidence and Mortality of Acute Myocardial Infarction in the Small Island Developing State of Barbados.

Objective To determine trends, identify predictors of acute myocardial infarction (AMI) incidence and mortality, and explore performance metrics for AMI care in Barbados. Methods Data on all cases diagnosed with AMI were collected by the Barbados National Registry for Non-Communicable Diseases (BNR) from the island's only tertiary hospital, the Queen Elizabeth Hospital, and the National Vital Registration Department. Participants who survived hospital admission were then followed up at 28 days and one year post event via telephone survey and retrieval of death certificates. Age-standardized incidence and mortality rates were calculated. Determinants of mortality at 28 days were examined in multivariable logistic regression models. Median and interquartile ranges (IQR) were calculated for performance metrics (e.g., time from pain onset to reperfusion). Results In a 10-year period between 2010 and 2019, 4,065 cases of myocardial infarction were recorded. The median age of the sample was 73 years (IQR: 61,83), and approximately half (47%) were female. Over a 10-year period, standardized incidence increased in women on average yearly by three per 100,000 (95% CI: 1 to 6; p=0.02), while in men, the average increase per year was six per 100,000 (95% CI: 4 to 8; p<0.001). There was no increase in 28-day mortality in women; mortality in men increased each year by 2.5 per 100,000 (95% CI: 0.4 to 4.5; p=0.02). The time from arrival at the hospital to the ECG was 44 minutes IQR (20,113). Conclusion AMI incidence and mortality are increasing in Barbados, and men have a higher velocity of mortality rate increase than women, which contradicts global data.

Gender differences in hepatitis A seropositivity rates according to the Republic of Korea's vaccination policy.

Objectives: This study aimed to investigate differences in the anti-hepatitis A (HAV) antibody seropositivity rate by age and gender. Methods: We collected information on anti-HAV immunoglobulin G and immunoglobulin M status from samples submitted for HAV antibody testing in 2012-2022. A total of 1,333,615 cases were included in the analysis. Results: By age, the seropositivity rate was represented by a U-shaped curve, such that the rate was low for the group aged 20 to 39 years and higher in those who were younger or older. Over time, the curve shifted rightward, and the seropositivity rate declined gradually in the group aged 35 to 39 years and older. A gender-based difference in antibody seropositivity rate was especially noticeable in the group aged 20 to 29 years. This difference between genders widened in the participants' early 20s-when men in the Republic of Korea enlist in the military-and the divergence continued subsequently for older individuals. Conclusion: These results indicate a higher risk of severe infection among older individuals and a gender-based difference in seroprevalence. Therefore, it is necessary to implement policies to promote vaccination in adults.

Procrastination Mediates the Relationship between Problematic TikTok Use and Depression among Young Adults.

Background: Although the prevalence of depression has increased significantly in recent years, especially in the young adult population, little is known about its causes and risk factors. The study aims to examine the mediating role of TikTok use in the relationships between procrastination and depression in young adults. Methods: A sample of 448 adults, ranging in age from 18 to 35 years (M = 24.45, SD = 3.76), including 214 men (48%), participated in the study. The cross-sectional survey consists of a modified Bergen Facebook Addiction Scale (BFAS) to assess problematic TikTok use (PTTU), the Pure Procrastination Scale (PPS) for procrastination measurement, and the nine-item Patient Health Questionnaire (PHQ-9) for screening depression symptoms. Results: The independent samples t-test indicates that emerging adults (ages ranging between 18 and 25 years) have more severe depression symptoms than young adults (26-35 years old). Gender differences were not found for procrastination, PTTU, and depression symptoms. Positive correlations were found between procrastination, PTTU, and depression symptoms. PTTU plays a mediating role in the associations between procrastination and depression. Conclusions: Both procrastination and PTTU treatment should be prioritized in the prevention and intervention programs for improving mental health among young adults. Some effective therapeutic methods are recommended.

Sex and gender differences in hepatitis C virus risk, prevention, and cascade of care in people who inject drugs: systematic review and meta-analysis.

Background: People who inject drugs (PWID) are a priority population in HCV elimination programming. Overcoming sex and gender disparities in HCV risk, prevention, and the cascade of care is likely to be important to achieving this goal, but these have not yet been comprehensively reviewed. Methods: Systematic review and meta-analysis. We searched Pubmed, EMBASE and the Cochrane Database of Systematic Reviews 1 January 2012-22 January 2024 for studies of any design reporting sex or gender differences among PWID in at least one of: sharing of needles and/or syringes, incarceration history, injection while incarcerated, participation in opioid agonist treatment or needle and syringe programs, HCV testing, spontaneous HCV clearance, direct-acting antiviral (DAA) treatment initiation or completion, and sustained virological response (SVR). Assessment of study quality was based on selected aspects of study design. Additional data were requested from study authors. Data were extracted in duplicate and meta-analysed using random effects models. PROSPERO registration CRD42022342806. Findings: 9533 studies were identified and 92 studies were included. Compared to men, women were at greater risk for receptive needle and syringe sharing (past 6-12 months: risk ratio (RR) 1.12; 95% confidence interval (CI) 1.01-1.23; <6 months: RR 1.38; 95% CI 1.09-1.76), less likely to be incarcerated (lifetime RR 0.64; 95% CI 0.57-0.73) more likely to be tested for HCV infection (lifetime RR 1.07; 95% CI 1.01, 1.14), more likely to spontaneously clear infection (RR1.58; 95% CI 1.40-1.79), less likely to initiate DAA treatment (0.84; 95% CI 0.78-0.90), and more likely to attain SVR after completing DAA treatment (RR 1.02; 95% CI 1.01-1.04). Interpretation: There are important differences in HCV risk and cascade of care indicators among people who inject drugs that may impact the effectiveness of prevention and treatment programming. Developing and assessing the effectiveness of gender-specific and gender-responsive HCV interventions should be a priority in elimination programming. Funding: Réseau SIDA-MI du Québec.

Gender differences in spinal mobility during postural changes: a detailed analysis using upright CT.

Lumbar spinal alignment is crucial for spine biomechanics and is linked to various spinal pathologies. However, limited research has explored gender-specific differences using CT scans. The objective was to evaluate and compare lumbar spinal alignment between standing and sitting CT in healthy individuals, focusing on gender differences. 24 young and 25 elderly males (M) and females (F) underwent standing and sitting CT scans to assess lumbar spinal alignment. Parameters measured and compared between genders included lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), lordotic angle (LA), foraminal height (FH), and bony boundary area (BBA). Females showed significantly larger changes in SS and PT when transitioning from standing to sitting (p = .044, p = .038). A notable gender difference was also observed in the L4-S LA among the elderly, with females showing a significantly larger decrease in lordotic angle compared to males (- 14.1° vs. - 9.2°, p = .039*). Females consistently exhibited larger FH and BBA values, particularly in lower lumbar segments, which was more prominent in the elderly group (M vs. F: L4/5 BBA 80.1 mm2 [46.3, 97.8] vs. 109.7 mm2 [74.4, 121.3], p = .019 in sitting). These findings underline distinct gender-related variations in lumbar alignment and flexibility, with a focus on noteworthy changes in BBA and FH in females. Gender differences in lumbar spinal alignment were evident, with females displaying greater pelvic and sacral mobility. Considering gender-specific characteristics is crucial for assessing spinal alignment and understanding spinal pathologies. These findings contribute to our understanding of lumbar spinal alignment and have implications for gender-specific spinal conditions and treatments.

Employment rates for working-age patients receiving hemodialysis increasing: Changing economic environment.

INTRODUCTION: This study explored employment trends among working-age patients undergoing hemodialysis using 5-year surveys from 1996 to 2021. Policy changes affecting individuals with disabilities, the economic environment, and employment status among the general population in Japan were considered. Differences in trends by gender and health status were examined. METHODS: Employment status was categorized into employment and nonemployment; and regular, nonregular, and self. Analytical data with similar characteristics were generated over the six surveys using the propensity score method. RESULTS: The employment rate, especially among women, increased from 1996 to 2021. However, the employment rate ratio to the general population was approximately 80% for men and 50% for women, even in 2021. The employment rate increased with an expansion in nonregular employment. Women's employment trends could be explained by changes in real gross domestic product and employment quotas for individuals with disabilities. CONCLUSION: Employment trends differ by gender and by regular versus nonregular employment.
