BACKGROUND: To overcome the limitations of the term \"non-alcoholic fatty liver disease\" (NAFLD), the term metabolic-associated steatotic liver disease (MASLD) was introduced. While epidemiologic studies have been conducted on MASLD, there is limited evidence on its associated sex and ethnic variations.
OBJECTIVE: This study assesses the differences across sex and race-ethnicity on the prevalence, associated risk factors and adverse outcomes in individuals with MASLD.
METHODS: Data retrieved from the National Health and Nutrition Examination Survey between 1999 to 2018 was analyzed. Prevalence, clinical characteristics, and outcomes were evaluated according to sex and race-ethnicity. Adverse outcomes and mortality events were analyzed using multivariate analyses.
RESULTS: Of 40,166 individuals included, 37.63% had MASLD. There was a significant increase in MASLD prevalence from 1999 to 2018 among Mexican Americans (Annual Percentage Change [APC] + 1.889%, p < 0.001), other Hispanics (APC + 1.661%, p = 0.013), NH Whites (APC + 1.084%, p = 0.018), NH Blacks (APC + 1.108%, p = 0.007), and females (APC + 0.879%, p = 0.030), but not males. Females with MASLD were at lower risk of all-cause (HR: 0.766, 95%CI 0.711 to 0.825, p < 0.001), cardiovascular disease-related (CVD) (SHR: 0.802, 95% CI 0.698 to 0.922, p = 0.002) and cancer-related mortality (SHR: 0.760, 95% CI 0.662 to 0.873, p < 0.001). Significantly, NH Blacks have the highest risk of all-cause and CVD-related mortality followed by NH Whites then Mexican Americans.
CONCLUSIONS: There has been an increase in prevalence in most race-ethnicities over time. While the change in definition shows no significant differences in previous associations found in NAFLD, the increased mortality in NH Whites relative to Mexican Americans remains to be explored.

UNASSIGNED: To evaluate the initial impact of a combined oral contraceptive (COC) containing norgestimate (NGM) on female sexuality and on circulating androgen levels in users.
UNASSIGNED: Six months modification in the McCoy Female Sexuality Questionnaire (MFSQ) and testosterone (T) and dehydroepiandrosterone sulphate (DHEAS) serum levels in women starting a monophasic pill containing ethinyl-estradiol (EE) 35 µg and NGM 0.250 mg.
UNASSIGNED: The study was completed by 36 subjects. There was a significant increase in MFSQ during treatment (p < 0.0001) (and its domains with the exclusion of vaginal lubrication domain) with concomitant decreases in T (-4.45%, p < 0.0001) and DHEAS (-19.41%, p < 0.0001) serum levels.
UNASSIGNED: Contraception with EE/NGM was associated with a short term non-deteriorating effect on sexuality despite the evident decrease in androgen levels. Female sexuality during COC use is a complex topic and is not only linked with changes in serum androgen levels.
EE/NGM treatment has a short term non-deteriorating effect on sexuality despite the evident decrease in androgen serum levels.

The introduction of vaccines marked a game changer in the fight against COVID-19. In sub-Saharan Africa, studies have documented the intention to vaccinate and the uptake of COVID-19 vaccines. However, little is documented about how sex differences could have impacted COVID-19 vaccination. We conducted a multi-country cross-sectional study to assess the sex differences in COVID-19 vaccine uptake and intention to vaccinate in the Democratic Republic of Congo (DRC), Nigeria, Senegal, and Uganda. This study involved analysis of data from mobile surveys conducted between March and June 2022 among nationally constituted samples of adults in each country. Bivariate and multivariable logistic regression models were run. The self-reported uptake of COVID-19 vaccines was not significantly different between males and females (p = 0.47), while the intention to vaccinate was significantly higher among males (p = 0.008). Among males, obtaining COVID-19 information from health workers, testing for COVID-19, and having high trust in the Ministry of Health were associated with higher vaccination uptake. Among females, having high trust in the government was associated with higher vaccination uptake. For intention to vaccinate, males who resided in semi-urban areas and females who resided in rural areas had significantly higher vaccination intention compared to their counterparts in urban areas. Other factors positively associated with vaccination intention among males were trust in the World Health Organization and perceived truthfulness of institutions, while males from households with a higher socio-economic index and those who had declined a vaccine before had a lower vaccine intention. Overall, the factors differentiating vaccine uptake and intention to vaccinate among males and females were mostly related to trust in government institutions, perceived truthfulness of institutions, and respondent\'s residence. These factors are key in guiding the tailoring of interventions to increase COVID-19 vaccine uptake in sub-Saharan Africa and similar contexts.

UNASSIGNED: There is controversy regarding sex differences in short-term mortality in acute type A aortic dissection (ATAAD).
UNASSIGNED: This study aimed to investigate the impact of sex differences on 30-day operative mortality after ATAAD surgery and to determine if other covariates modify the association.
UNASSIGNED: Consecutive patients (N = 5670) with surgically repaired ATAAD were identified from the multicenter China 5A study. The primary outcome was operative mortality. The age dependency was modeled using a cubic spline curve.
UNASSIGNED: There were 1,503 females (26.5%) and 4,167 males (73.5%). Females were older and had a lower percentage of comorbidities compared with males. Females had higher mortality compared to males (10.2% vs 8.2%, P = 0.019); however, there was no difference after propensity analyses (adjusted OR: 1.334 [95% CI: 0.918-1.938]). There was an interaction with sex and age (P interaction = 0.035): older age was associated with higher odds of operative mortality among females (OR: 1.045 [95% CI: 1.029-1.061]) compared with males (OR: 1.025 [95% CI: 1.016-1.035]). The risk of mortality for males and females appears to diverge at 55 years of age (P interaction = 0.019): females under 55 years of age had similar odds to males (OR: 0.852 [95% CI: 0.603-1.205]) but higher odds when over 55 years (OR: 1.420 [95% CI: 1.096-1.839]) compared to males.
UNASSIGNED: Under the age of 55 years, females have similar odds of operative mortality compared with males; however, over the age of 55 years females have higher odds than males. Understanding differences in risk allows for individualized treatment strategies. (Additive Anti-inflammatory Action for Aortopathy & Arteriopathy; NCT04398992).
