RESUMO
OBJECTIVES: To evaluate the diagnostic performance of ultrasound guided attenuation parameter (UGAP) for evaluating liver fat content with different probe forces and body positions, in relation to sex, and compared with proton density fat fraction (PDFF). METHODS: We prospectively enrolled a metabolic dysfunction-associated steatotic liver disease (MASLD) cohort that underwent UGAP and PDFF in the autumn of 2022. Mean UGAP values were obtained in supine and 30° left decubitus body position with normal 4 N and increased 30 N probe force. The diagnostic performance was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS: Among 60 individuals (mean age 52.9 years, SD 12.9; 30 men), we found the best diagnostic performance with increased probe force in 30° left decubitus position (AUC 0.90; 95% CI 0.82-0.98) with a cut-off of 0.58 dB/cm/MHz. For men, the best performance was in supine (AUC 0.91; 95% CI 0.81-1.00) with a cut-off of 0.60 dB/cm/MHz, and for women, 30° left decubitus position (AUC 0.93; 95% CI 0.83-1.00), with a cut-off 0.56 dB/cm/MHz, and increased 30 N probe force for both genders. No difference was in the mean UGAP value when altering body position. UGAP showed good to excellent intra-reproducibility (Intra-class correlation 0.872; 95% CI 0.794-0.921). CONCLUSION: UGAP provides excellent diagnostic performance to detect liver fat content in metabolic dysfunction-associated steatotic liver diseases, with good to excellent intra-reproducibility. Regardless of sex, the highest diagnostic accuracy is achieved with increased probe force with men in supine and women in 30° left decubitus position, yielding different cut-offs. CLINICAL RELEVANCE STATEMENT: The ultrasound method ultrasound-guided attenuation parameter shows excellent diagnostic accuracy and performs with good to excellent reproducibility. There is a possibility to alter body position and increase probe pressure, and different performances for men and women should be considered for the highest accuracy. KEY POINTS: ⢠There is a possibility to alter body position when performing the ultrasound method ultrasound-guided attenuation parameter. ⢠Increase probe pressure for the highest accuracy. ⢠Different performances for men and women should be considered.
RESUMO
INTRODUCTION: There is evidence that sex differences exist in stroke presentation, risk factors, severity, treatment, and outcomes. To further understand this, we explored how sex differences influence acute stroke management, secondary prevention prescribing, and mortality outcomes in a well-characterised cohort of first-ever stroke patients in Scotland. METHODS: This is a retrospective, population-based, data-linkage study of stroke admissions to acute care hospitals in Scotland between January 1, 2011, and December 31, 2018. Data sources included the Scottish Stroke Care Audit (SSCA), the Prescribing Information System (PIS), the Scottish Morbidity Record 01 (SMR01), and the National Records of Scotland (NRS) death records. Multivariable logistic regression was used to explore the association between patient sex, acute stroke care, and secondary prevention prescribing, while Cox proportional hazards models were used to explore the association between patient sex and all-cause mortality up to 1 year after index event. RESULTS: This study included 5,901 patients with a first-ever intracerebral haemorrhage (ICH) and 47,087 patients with a first-ever acute ischaemic stroke (AIS). After an ICH, women had significantly lower odds of receiving all components of the stroke care bundle (adjusted odds ratio [aOR], 0.78; 95% confidence interval [CI], 0.69-0.87) and were less likely to be prescribed antihypertensives within 90 days after discharge to the usual place of residence (aOR, 0.78; 95% CI, 0.63-0.97). There was no sex difference in stroke care bundle achievement for those admitted with AIS; however, women had significantly lower odds of receiving antihypertensives, lipid-lowering drugs, or oral anticoagulants after discharge. The risk of all-cause mortality was lower in women at 1 year after both ICH (adjusted hazard ratio [aHR], 0.90; 95% CI, 0.83-0.98) and AIS (aHR, 0.91; 95% CI, 0.87-0.95) after adjusting for potential confounders. CONCLUSION: The sex differences in stroke treatment and outcomes may be partly explained by the older age of women at the time of stroke, which influences stroke presentation, severity, and prognosis. However, following adjustment, women had a reduced risk of all-cause mortality after both ICH and AIS.
RESUMO
PURPOSE: Epidemiological TB data indicate differences in infection prevalence, progression rates, and clinical disease incidence between sexes. In contrast, evidence on sex-specific differential (post) TB case fatality in Europe has not been synthesized systematically. METHODS: We searched electronic databases and grey literature up to December 2020 for studies reporting sex-stratified TB death data for Europe. The JBI critical appraisal tools served for bias risk assessment and subgroup analyses for studying heterogeneity. Random-effects models meta-analyses enabled estimating pooled relative risks of sex-associated TB fatality. Considering associations of comorbidities and risk factors on fatality differences, we applied relative risk meta-regression. RESULTS: Based on 17,400 records screened, 117 studies entered quantitative analyses. Seventy-five studies providing absolute participant data with moderate quality and limited sex stratification reported 33 to 235,000 TB cases and 7 to 27,108 deaths. The pooled male-to-female TB fatality risk ratio was 1.4 [1.3-1.5]. Heterogeneity was high between studies and subgroups. Study time, concurrent comorbidities (e.g., HIV, diabetes, cancers), and mean participant ages showed no effect modification. We identified higher male TB fatality in studies with higher homelessness (coefficient 3.18, 95% CI [-0.59 to 6.94], p-value 0.10) and lower migrants proportion (coefficient - 0.24, 95% CI [- 0.5 to 0.04], p-value 0.09). CONCLUSION: We found 30-50% higher TB case fatality for males in Europe. Except for homelessness, migration, and a trend for some comorbidities, assessing effect modification could not reduce our meta-analysis' high heterogeneity. Public health authorities should take heed of this higher risk of dying in male patients' treatment services.
RESUMO
Rationale: Women have worse outcomes than men in several conditions more common in men, including cardiac surgery and burns. Objectives: To describe the relationship between sex balance within each diagnostic group of ICU admissions, defined as the percentage of patients who were women, and hospital mortality of women compared with men with that same diagnosis. Methods: We studied ICU patients in the Australian and New Zealand Intensive Care Society's Adult Patient Database (2011-2020). We performed mixed effects logistic regression for hospital mortality adjusted for sex, illness severity, ICU lead time, admission year, and hospital site. We compared sex balance with the adjusted hospital mortality of women compared with men for each diagnosis using weighted linear regression. Measurements and Main Results: There were 1,450,782 admissions (42.1% women), with no difference in the adjusted hospital mortality of women compared with men overall (odds ratio, 0.99; 99% confidence interval [CI], 0.97 to 1). As the percentage of women within each diagnosis increased, the adjusted mortality of women compared with men with that same diagnosis decreased (regression coefficient, -0.015; 99% CI; -0.020 to -0.011; P < 0.001), and the illness severity of women compared with men at ICU admission decreased (regression coefficient, -0.0026; 99% CI, -0.0035 to -0.0018; P < 0.001). Conclusions: Sex balance in diagnostic groups was inversely associated with both the adjusted mortality and illness severity of women compared with men. In diagnoses with relatively few women, women were more likely than men to die. In diagnoses with fewer men, men were more likely than women to die.

BACKGROUND: There are several differences in the clinical course of hypertension due to the biological and social differences between men and women. Resistant hypertension is an advanced disease state, and significant gender difference could be expected, but much has not been revealed yet. The purpose of this study was to compare gender differences on the current status of blood pressure (BP) control and clinical prognosis in patients with resistant hypertension. METHODS: This is a multicenter, retrospective cohort study using common data model databases of 3 tertiary hospitals in Korea. Total 4,926 patients with resistant hypertension were selected from January 2017 to December 2018. Occurrence of dialysis, heart failure (HF) hospitalization, myocardial infarction, stroke, dementia or all-cause mortality was followed up for 3 years. RESULTS: Male patients with resistant hypertension were younger but had a higher cardiovascular risk than female patients. Prevalence of left ventricular hypertrophy and proteinuria was higher in men than in women. On-treatment diastolic BP was lower in women than in men and target BP achievement rate was higher in women than in men. During 3 years, the incidence of dialysis and myocardial infarction was higher in men, and the incidence of stroke and dementia was higher in women. After adjustment, male sex was an independent risk factor for HF hospitalization, myocardial infarction, and all-cause death. CONCLUSION: In resistant hypertension, men were younger than women, but end-organ damage was more common and the risk of cardiovascular event was higher. More intensive cardiovascular prevention strategies may be required in male patients with resistant hypertension.

PURPOSE: To evaluate gestational age (GA) and small-for-gestational age (SGA) as continuums and gender on the incidences of autism spectrum disorder (ASD) and co-occurring intellectual disability (ID). METHODS: This is a population-based cohort study using the 2004-2008 Taiwan Maternal and Child Health Database. The diagnosis of ASD was determined by International Classification of Diseases, 9th Revision (ICD-9). Generalized estimating equations models were fit to evaluate associations between perinatal variables and ASD. RESULTS: This study included 916,315 individuals. A total of 9474 (1.0%) children were diagnosed with ASD, among whom 1594 (16.8%) had co-occurring ID. Lower GA carried higher odds of ASD with ID (GA < 28 weeks, aOR: 4.26, 95% CI: 2.13, 8.50; GA 28-30 weeks, aOR: 2.80, 95% CI: 1.57, 4.97; GA 31-33 weeks, aOR: 1.63, 95% CI: 1.05, 2.55; GA 34-36 weeks, aOR: 1.39, 95% CI: 1.16, 1.67) and ASD without ID (GA < 28 weeks, aOR:2.05, 95% CI: 1.25, 3.36; GA 28-30 weeks, aOR: 2.02, 95% CI: 1.46, 2.79; GA 31-33 weeks, aOR: 1.42, 95% CI: 1.13, 1.77; GA 34-36 weeks, aOR: 1.18, 95% CI: 1.08, 1.29). Male preterm infants had ASD risks negatively correlated to GA, while ASD risks were significantly increased only among female infants born late preterm. The degree of SGA showed a stepwise increased risk for ASD with and without ID in both male and female infants. CONCLUSION: Lower GA and the degree of SGA are both associated with ASD susceptibility, either with or without co-occurring ID, and remarkably increased the risk of ID.

BACKGROUND: Women are underrepresented in orthopaedic surgery, especially in Japan. Authorship is associated with representation and career advancement, but the academic representation of women in Japanese orthopaedic surgery has not been elucidated. This study aimed to elucidate the proportion of female first authorship and its associating factors, as well as trends in the Journal of Orthopaedic Science (JOS), the official journal of the Japanese Orthopaedic Association. METHODS: The study reviewed original articles published in JOS from 2002 to 2021 using data from PubMed on March 16, 2022. The gender of the first and last authors was determined using genderize. io, an online gender detection tool and manual search. The study used multivariable logistic regression to identify the factors associated with female first authorship and visualized the trend of predicted probability using restricted cubic spline curve. RESULTS: Among 2272 original articles, 148 (6.5%) and 79 (3.5%) had female first and last authors, respectively. Compared with 2002-2006, female first authorship significantly increased in 2012-2016 (adjusted odds ratio [aOR], 2.04; 95% confidence interval [CI], 1.09-4.05; p = 0.03) and 2017-2021 (aOR, 2.72; 95% CI, 1.46-5.276; p = 0.002). Affiliation with an institution in Japan (aOR, 0.51; 95% CI, 0.35-0.74; p < 0.001) and affiliation in orthopaedics (aOR, 0.16; 95% CI, 0.11-0.23; p < 0.001) were negatively associated with female first authorship. Around 2020, the trend showed a gradual then rapid increase in women with non-orthopaedic affiliations. Only a very small increase was observed in women with an orthopaedic affiliation. CONCLUSIONS: Female first authorship in JOS has been increasing. However, the proportion of female authors remains low. Authors outside of Japan and not affiliated with orthopaedics largely affect female authorship statistics. The results indicate the persistent gender gap in the academic representation of women in Japanese orthopaedic publications.
RESUMO
Objectives: To investigate the effect of gender on the activation ratio of vastus medialis oblique to vastus lateralis during straight leg raising and stepdown activities. Method: The cross-sectionalstudy was conducted at the College of Medical Rehabilitation Sciences, Taibah University, Medina, Kingdom of Saudi Arabia, from September 2021 to March 2022, and comprised recreationally active subjects without knee pathology who were distributed in 2 gender-based groups. All the participants were subjected to straight leg raising and stepdown activitiesthrice and the average value of each activity was noted. The vastus medialis oblique and vastus lateralis electromyographic activity of the dominant limb was recorded using surface electromyography during the activities. The normalised value of the activation ratio of vastus medialis oblique to vastus lateralis levels was calculated. Data was analysed using SPSS 25. RESULTS: Of the 60 subjects, there were 30(50%) males with mean age 30.00±5.91 years, mean height 167±5.63cm, mean body weight 66.76±6.14kg, and mean body mass index 23.97±3.02kg/m2 . There were 30(50%) females with mean age 29.03±5.34 years, mean height 186±6.20cm, mean body weight 68.5±5.6 kg and mean body mass index 23.76±3.22 kg/m2 . There was no significant difference in the normalized electromyography activities of the vastus medialis oblique and vastuslateralis muscles between males and females(p>0.05). Also, no significant difference was found in the activation ratio between the genders (p>0.05). CONCLUSIONS: There were no gender-based differencesin the activation ratio of vastus medialis oblique to vastuslateralis during weight-bearing and non-weight-bearing activities.

OBJECTIVE: Although sex differences in endovascular abdominal aortic aneurysm repair (EVAR) outcomes have been increasingly reported, the determination of contributing factors has not reached a consensus. We investigated the disparities in sex-specific outcomes after elective EVAR at our institution and evaluated the factors that might predispose women to increased morbidity and mortality. METHODS: We performed a retrospective medical record review of all patients who had undergone elective EVAR from 2011 to 2020 at a suburban tertiary care center. The primary outcomes were 5-year survival and freedom from reintervention. The Fisher exact test, t tests, and Kaplan-Meier analysis using the rank-log test were used to investigate the associations between sex and outcomes. A multivariable Cox proportional hazard model controlling for age and common comorbidities evaluated the effect of sex on survival and freedom from reintervention. RESULTS: A total of 273 patients had undergone elective EVAR during the study period, including 68 women (25%) and 205 men (75%). The women were older on average than were than the men (76 years vs 73 years; P ≤ .01) and were more likely to have chronic obstructive pulmonary disease (38% vs 23%; P = .01), require home oxygen therapy (9% vs 2%; P = .04), or dialysis preoperatively (4% vs 0%; P = .02). The distribution of other common vascular comorbidities was similar between the sexes. The 30-day readmission rate was greater for the women than for the men (18% vs 8%; P = .02). The women had had significantly lower survival at 5 years (48% ± 7.9% vs 65% ± 4.3%; P < .01) and significantly lower 1-year (women, 89% ± 4.1%; vs men, 94% ± 1.7%; P = .01) and 5-year (women, 69% ± 8.9%; vs men, 84% ± 3.3%; P = .02) freedom from reintervention. On multivariable analysis, female sex (hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.1-2.9), congestive heart failure (HR, 2.2; 95% CI, 1.2-3.9), and older age (HR, 1.1; 95% CI, 1.0-1.1) were associated with 5-year mortality. Female sex remained as the only variable with a statistically significant association with 5-year reintervention (HR, 2.4; 95% CI, 1.1-4.9). CONCLUSIONS: Female sex was associated with decreased 5-year survival and increased 1- and 5-year reintervention after elective EVAR. Data from our institution suggest that factors beyond patient age and baseline health risk likely contribute to greater surgical morbidity and mortality for women after elective EVAR.

BACKGROUND: Despite the World Health Organization calling for sexuality to be recognized as an aspect of well-being, no studies have explored sexual activity and physical tenderness in older adults aged ≥ 75 years in Belgium or those aged ≥ 85 years worldwide. AIM: To assess the prevalence and predictors of sexual activity and physical tenderness in a sample of older adults. METHODS: Using data from a Belgian cross-sectional study on sexual violence (UN-MENAMAIS), information on sexual activity, physical tenderness, and associated characteristics was collected during structured face-to-face interviews with older adults living in the community, assisted living facilities, or nursing homes. Cluster random probability sampling with a random route-finding approach was used to select the participants. OUTCOMES: Current sexual activity and physical tenderness in the previous 12 months, sociodemographic characteristics, chronological age, subjective age, number of sexual partners, sexual satisfaction, attitudes toward sexuality in later life, quality of life, and lifetime sexual victimisation. RESULTS: Among the 511 participants included, 50.3% were in a relationship, mainly living with their partner; 31.3% indicated they were sexually active; and 47.3% of sexually inactive participants reported having experienced forms of physical tenderness in the previous 12 months. Sexual activity was associated with the presence of a partner, satisfaction with sexual life, permissive attitudes regarding sexuality in later life, a younger age, and a lack of disability. Physical tenderness was associated with the presence of a partner, community residency, and permissive attitudes regarding sexuality in later life. CLINICAL IMPLICATIONS: Raising awareness among the general population, healthcare professionals, and older adults about sexuality in later life could contribute to ending this taboo and should therefore be a priority for society. STRENGTHS AND LIMITATIONS: Our study fills a gap in the literature regarding sexual activity and physical tenderness in older adults aged ≥ 70 years, including respondents aged up to 99 years. Additionally, we explored different forms of sexual expression beyond intercourse, and face-to-face interviews contributed to the quality of the collected data. The main limitation of this study was the sample size, although the findings were similar to recent statistical indicators in Belgium. CONCLUSION: One in 3 older adults aged ≥ 70 years living in Belgium are sexually active. These findings provide an opportunity to inform the general public and older adults about later life sexuality and to educate healthcare professionals about aging sexuality to increase discussions and avoid assumptions of asexuality in later life.

The extent of sotalol-induced QTc prolongation on the electrocardiogram, is variable among subjects and influenced by sex. However, the influence of baseline QTc on the extent of drug-induced QTc prolongation remains unclear. This was studied around peak plasma concentration in a large cohort of 376 healthy male and 614 healthy female subjects who received 80 mg of sotalol orally. Baseline QTc was 379 ± 16 ms in men and 393 ± 15 ms in women (P < .0001). The change in QTc from baseline was highly variable among both sexes and was greater in women than in men (26.5 ± 13.2 vs.13.0 ± 10.8 ms; P < .0001). The slope of the regression line between QTc on sotalol and baseline QTc did not significantly differ from unity in men and in women, indicating that the extent of QTc prolongation with sotalol was not influenced by baseline QTc. Assessing QTc after administration of an IKr blocker may be more important than measuring a baseline QTc.

BACKGROUND: Despite diversity initiatives, inequities persist in medicine with negative implications for the workforce and patients. Little is known about workplace inequity in nephrology. AIM: To describe perceptions and experiences of bias by health professionals in the Australian and New Zealand Society of Nephrology (ANZSN), focussing on gender and race. METHODS: A web-based survey of ANZSN members recorded degree of perceived inequity on a Likert scale, ranging from 1 (none) to 5 (complete). Groups were compared using Mann-Whitney U-test and logistic regression. Comments were synthesised using qualitative methods to explore themes of inequity and pathways to an inclusive future. RESULTS: Of the 620 members of the ANZSN, there were 134 (22%) respondents, of whom 57% were women and 67% were White. The majority (88%) perceived inequities in the workforce. Perceived drivers of inequity were gender (84/113; 75%), carer responsibilities (74/113; 65%) and race (64/113; 56%). Half (74/131) had personally experienced inequity, based on gender in 70% (52/74) and race in 39% (29/75) with perceived discrimination coming from doctors, patients, academics and health administrators. White males were least likely (odds ratio 0.39; 95% confidence interval 0.18-0.90) to experience inequity. Dominant themes from qualitative analysis indicated that the major impacts of inequity were limited opportunities for advancement and lack of formal assistance for those experiencing inequities. Proposed solutions to reduce inequity included normalising the discourse on inequity at an organisational level, with policy changes to ensure diverse representation on committees and in executive leadership positions. CONCLUSIONS: Inequity, particularly driven by gender and race, is common for nephrology health professionals in Australia and New Zealand and impacts career progression.

RATIONALE & OBJECTIVE: Cardiovascular events are less common in women than men in general populations; however, studies in chronic kidney disease (CKD) are less conclusive. We evaluated sex-related differences in cardiovascular events and death in adults with CKD. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 1,778 women and 2,161 men enrolled in the Chronic Renal Insufficiency Cohort (CRIC). EXPOSURE: Sex (women vs men). OUTCOME: Atherosclerotic composite outcome (myocardial infarction, stroke, or peripheral artery disease), incident heart failure, cardiovascular death, and all-cause death. ANALYTICAL APPROACH: Cox proportional hazards regression. RESULTS: During a median follow-up period of 9.6 years, we observed 698 atherosclerotic events (women, 264; men, 434), 762 heart failure events (women, 331; men, 431), 435 cardiovascular deaths (women, 163; men, 274), and 1,158 deaths from any cause (women, 449; men, 709). In analyses adjusted for sociodemographic, clinical, and metabolic parameters, women had a lower risk of atherosclerotic events (HR, 0.71 [95% CI, 0.57-0.88]), heart failure (HR, 0.76 [95% CI, 0.62-0.93]), cardiovascular death (HR, 0.55 [95% CI, 0.42-0.72]), and death from any cause (HR, 0.58 [95% CI, 0.49-0.69]) compared with men. These associations remained statistically significant after adjusting for cardiac and inflammation biomarkers. LIMITATIONS: Assessment of sex hormones, which may play a role in cardiovascular risk, was not included. CONCLUSIONS: In a large, diverse cohort of adults with CKD, compared with men, women had lower risks of cardiovascular events, cardiovascular mortality, and mortality from any cause. These differences were not explained by measured cardiovascular risk factors.

OBJECTIVES: Studies examining the impact of adolescent and young adult cannabis use on structural outcomes have been heterogeneous. One already-identified moderator is sex, while a novel potential moderator is extent of aerobic fitness. Here, we sought to investigate the associations of cannabis use, sex, and aerobic fitness levels on brain volume. Second, we explored brain-behavior relationships to interpret these findings. METHODS: Seventy-four adolescents and young adults (36 cannabis users and 38 controls) underwent 3 weeks of monitored cannabis abstinence, aerobic fitness testing, structural neuroimaging, and neuropsychological testing. Linear regressions examined cannabis use and its interaction with sex and aerobic fitness on whole-brain cortical volume and subcortical regions of interests. RESULTS: No main-effect differences between cannabis users and nonusers were observed; however, cannabis-by-sex interactions identified differences in frontal, temporal, and paracentral volumes. Female cannabis users generally exhibited greater volume while male users exhibited less volume compared to same-sex controls. Positive associations between aerobic fitness and frontal, parietal, cerebellum, and caudate volumes were observed. Cannabis-by-fitness interaction was linked with left superior temporal volume. Preliminary brain-behavior correlations revealed that abnormal volumes were not advantageous in either male or female cannabis users. CONCLUSIONS: Aerobic fitness was linked with greater brain volume and sex moderated the effect of cannabis use on volume; preliminary brain-behavior correlations revealed that differences in cannabis users were not linked with advantageous cognitive performance. Implications of sex-specific subtleties and mechanisms of aerobic fitness require large-scale investigation. Furthermore, present findings and prior literature on aerobic exercise warrant examinations of aerobic fitness interventions that aimed at improving neurocognitive health in substance-using youth.

PURPOSE: Excessive daytime sleepiness (EDS) is a main symptom in patients with obstructive sleep apnea (OSA); however, patients with OSA have significant variability in their reported EDS which cannot be fully explained by the apnea-hypopnea index (AHI). The purpose of this study was to investigate gender differences regarding the sleep test variables contributing to excessive daytime sleepiness. METHODS: Retrospective study of 578 men and 270 women with suspected OSA who underwent home overnight sleep test. We assessed the correlation between sleep test variables and EDS, using the Epworth Sleepiness Scale (ESS). RESULTS: Among the group of men, correlation was found between ESS to BMI (r = .107, p = .010), AHI (r = .158, p < .001), number of apneas (r = .129, p = .002), number of hypopneas (r = .115, p = .006), number of blood oxygen desaturations (r = .145, p < .001), and percent of time the blood oxygen saturation was under 90% (r = .130, p = .002). However, among the group of women, no significant correlation was found between any of the sleep test parameters or BMI to ESS. Among the group of women, a negative correlation was found between age and EDS (r = - .208, p < .001). CONCLUSION: Men showed correlations between sleep test variables and EDS, while women did not show such correlations. The results suggest that men's sleepiness is more influenced by OSA and sleep variables compared to women. To our knowledge, this is the first study which shows difference between genders in the influence of sleep variables and OSA on EDS.

Previous studies have confirmed the sex difference of gray matter asymmetry in typically developing controls and the abnormal gray matter asymmetry in autism spectrum disorders. However, whether and how sex differences of gray matter asymmetry exist in autism spectrum disorders remains studied. This paper analyzes the above issues and explores correlations between gray matter asymmetry and autistic symptoms. Data from 72 children (36 males and 36 females) with autism spectrum disorders and 72 typically developing-controls (36 males and 36 females) between 8 and 14 years were included and obtained from the autism brain imaging data exchange repository (autism brain imaging data exchange I and autism brain imaging data exchange II). The voxel-based morphometry approach was used to assess gray matter asymmetry in T1-weighted brain data, and gray matter asymmetry was quantified as asymmetry index. A 2 × 2 analysis of covariance was used to identify asymmetry index differences among the four groups. Pearson correlation analysis was performed for asymmetry index values extracted from the clusters with significant differences between the four groups and autistic symptoms (social impairments, communication difficulties, and restricted, repetitive behaviors) measured by the revised autism diagnostic interview scale. Results showed that specific brain regions showed significant main effects for diagnosis in which autism spectrum disorders patients had more leftward asymmetry than typically developing-controls for the parahippocampal gyrus and the postcentral gyrus; specific brain regions showed significant main effects for sex in which females showed more rightward asymmetry for the middle temporal gyrus, inferior frontal gyrus, angular gyrus, and postcentral gyrus and minor rightward asymmetry for the superior frontal gyrus than males; significant diagnosis × sex interaction effects were identified in the angular gyrus and middle occipital gyrus. Pearson correlation analysis showed that males with autism spectrum disorders had a positive association between the asymmetry index value in the middle occipital gyrus and more significant verbal impairment measured by the revised autism diagnostic interview (r = 0.387, p = 0.026). The asymmetry index value in the parahippocampal gyrus was positively associated with more severe social impairment in females with autism spectrum disorders (r = 0.422, p = 0.020). We identified that the sex difference of gray matter asymmetry in children with autism spectrum disorders is qualitative rather than quantitative, which is relatively novel. Our findings provide the theoretical basis for conducting separate studies and using sex-specific diagnostic methods and treatments for males and females children with autism spectrum disorders.

BACKGROUND: Veterans are more likely than other Canadians to have chronic health conditions, making access to health care an important issue. However, little research has addressed health care access and use among veterans. This paper examines access and use among veterans compared with other Canadians. DATA AND METHODS: Health care access and use indicators were examined for Regular Force veterans using the 2016 Life After Service Survey. Information for male and female veterans was compared with information on the Canadian general population from the 2015 and 2016 Canadian Community Health Survey, using age-adjusted rates and 95% confidence intervals. RESULTS: More than 80% of male and female veterans reported having a regular medical doctor in the 12 months before the survey. The majority of veterans (71% of males and 81% of females) had consulted a family doctor, while a minority had been hospitalized (8% of males and females). These rates were similar to those in the Canadian general population. However, veteran consultation rates for mental health care and with audiologists, speech therapists or occupational therapists among both sexes were double to triple those of the Canadian general population. Among veterans, males reported lower rates of unmet needs compared with females. DISCUSSION: Veterans had similar rates of access to a regular medical doctor and higher rates of use compared with other Canadians. However, these may be comparatively low, given previous findings on higher rates of disability and some chronic conditions among veterans. Noted differences between males and females highlight the importance of research and services that account for sex and gender. The extent to which health care needs explain health care use and barriers to care requires further research.

BACKGROUND: A person's sex is suggested to impact their outcome after acute coronary syndrome (ACS) and cardiac surgery, although evidence in controversial. This study examined sex differences in outcomes of ACS patients treated with coronary artery bypass grafting (CABG). METHODS: Patients aged ≥18 year with ACS and treated with first-time isolated CABG in Finland between 2004-2014 were retrospectively identified from a national registry (n=6,683, 24% women). Propensity score matching (1:1) was used to identify 1,607 women and 1,607 men with comparable baseline features (mean age 71 years and follow-up 7.1 years). In-hospital outcomes of all matched patients and long-term (10-year) outcomes of hospital survivors were studied. RESULTS: Women had higher in-hospital mortality (4.5 vs 2.6%; HR, 1.83; 95% CI, 1.18-2.86; p=0.008) but lower long-term all-cause mortality (28.3 vs 34.4%; HR, 0.70; 95% CI, 0.58-0.84; p<0.0001) and cardiovascular mortality (19.5 vs 23.7%; HR, 0.69; 95% CI, 0.55-0.86; p=0.001) as well as long-term major bleeding (11.6 vs 13.6%; HR, 0.69; 95% CI, 0.49-0.97; p=0.032). Re-sternotomy was also less common among women (3.7 vs 5.4%; OR 0.69; CI 0.49-0.96; p=0.029). There were no differences in length of stay (8.8 days in women vs 9.0 days in men) or in the occurrence of a composite major adverse cardiovascular event (MACE) in long-term follow-up (43.0% in women vs 46.5% in men; p=0.800). CONCLUSIONS: Outcomes after CABG-treated ACS differed between sexes. Women had higher in-hospital mortality, while men had higher long-term mortality and occurrence of major bleeding. The long-term risk of combined MACE was comparable between sexes.

OBJECTIVE: The couples coping with cancer together program (CCCT) is used to illustrate practical strategies to implement, evaluate, and grow a successful couples-based program in an NCI-designated CCC. CCCT is multimodal program utilizing psychoeducational, strategic, strengths-based, and problem-solving theoretical frameworks. CCCT integrates multiple intervention modalities, as the standard of care: patients/partners biopsychosocial screening, a standardized psychoeducational session, group intervention, and short-term couples counseling. METHODS: Implementation strategies included: (a) identifying Values-Benefits-Outcomes for key stakeholders, (b) recruiting an interdisciplinary team, (c) utilizing a concurrent development model (implementing program components in small iterations), (d) integrating program into existing institutional processes, and (e) collecting data and credibility. RESULTS: CCCT prospectively screened 1995 patients/partners simultaneously for biopsychosocial distress and 913 patient/partner completed program evaluations. Program satisfaction was extremely high: "I recommend this program, for other patients/partners (Patients 95.4% Partners 96.4%)." Ten of the 11 participating physicians anonymously surveyed responded and indicated 100% likely/very likely "to recommend the program to other physicians." CONCLUSIONS: Couples-based programs are underutilized and have been shown to be important for adjustment and increased longevity. Despite barriers in the healthcare environment, implementing couples-based programs into standard of care are feasible. These strategies may be applicable to develop supportive care programs in various health-care settings.
