RESUMO

Parental communication about sex is an important aspect of sexual socialization. However, research has primarily focused on sexual communication's presence, frequency, or topics, with less research on the specific messages parents communicate. Further, few studies have differentiated between communication received before and after youth initiated sex. Therefore, in this paper, we coded open-ended survey responses to explore the sex-related messages young adults report receiving from their caregiver(s) before they began engaging in sex. As part of a larger study, 381 U.S. young adults (Mage = 21.0 years, SD = 2.0) completed an online survey and responded to an open-ended question about messages their caregiver(s) communicated before they began engaging in sex. Participants identified as cisgender women (62.2%), cisgender men (12.1%), and gender diverse (25.7%), and were primarily lesbian, gay, bisexual, queer, questioning, or otherwise non-heterosexual (LGBQ+; 70.6%) young adults. Through thematic analysis, we identified six themes for caregivers' sex-related messages: sex-restrictive, safety and consequences, no, negative, sex-positive, and informational messages. In addition, we found that messages varied by young adults' gender identity and sexual orientation. Our findings suggest that young adults may not receive proper education about healthy sexual relationships and demonstrate the need for interventions with caregivers, as well as sexual health resources for adolescents and young adults, particularly LGBTQ+ youth.

RESUMO

BACKGROUND: Krüppel-like factor 10 (KLF10), a zinc finger transcription factor, plays a pivotal role in modulating TGF-ß-mediated cellular processes such as growth, apoptosis, and differentiation. Recent studies have implicated KLF10 in regulating lipid metabolism and glucose homeostasis. This study aimed to elucidate the precise role of hepatic KLF10 in developing metabolic dysfunction-associated steatohepatitis (MASH) in diet-induced obese mice. METHODS: We investigated hepatic KLF10 expression under metabolic stress and the effects of overexpression or ablation of hepatic KLF10 on MASH development and lipidemia. We also determined whether hepatocyte nuclear factor 4α (HNF4α) mediated the metabolic effects of KLF10. RESULTS: Hepatic KLF10 was downregulated in MASH patients and genetically or diet-induced obese mice. AAV8-mediated overexpression of KLF10 in hepatocytes prevented Western diet-induced hypercholesterolemia and steatohepatitis, whereas inactivation of hepatocyte KLF10 aggravated Western diet-induced steatohepatitis. Mechanistically, KLF10 reduced hepatic triglyceride and free fatty acid levels by inducing lipolysis and fatty acid oxidation and inhibiting lipogenesis, and reducing hepatic cholesterol levels by promoting bile acid synthesis. KLF10 highly induced HNF4α expression by directly binding to its promoter. The beneficial effect of KLF10 on MASH development was abolished in mice lacking hepatocyte HNF4α. In addition, the inactivation of KLF10 in hepatic stellate cells exacerbated Western diet-induced liver fibrosis by activating the TGF-ß/SMAD2/3 pathway. CONCLUSIONS: Our data collectively suggest that the transcription factor KLF10 plays a hepatoprotective role in MASH development by inducing HNF4α. Targeting hepatic KLF10 may offer a promising strategy for treating MASH.

RESUMO

Desire discrepancies are a common source of relationship conflict and one reason adults may seek couples counseling. Within romantic relationships, adults individually experience sexual and affectionate desire, but also experience desire relative to their partner. If desire discrepancies exist, partners may attempt to resolve these discrepancies. Thus, we examined adults' strategies for managing sexual and affectionate desire discrepancies. Our sample consisted of 300 adults (45% women; Mage = 29.5; 86.3% LGBTQ+) who were in a romantic relationship and reported a desire discrepancy. Thematic analysis revealed five strategies for managing desire discrepancies: alternative behaviors, communication, doing nothing, engaging in behaviors anyway, and giving control to a specific partner. Adults reported similar strategies for resolving sexual and affectionate desire discrepancies. Perceived effectiveness and strategies varied by whether adults thought that their discrepancies were problematic. Our findings hold implications for clinicians approaching problematic desire discrepancies, and suggest strategies that may promote effective resolutions.

RESUMO

Forkhead transcription factor 3 (FOXA3) has been shown to regulate metabolism and development. Hepatic FOXA3 is reduced in obesity and fatty liver disease. However, the role of hepatic FOXA3 in regulating obesity or steatohepatitis remains to be investigated. In this work, C57BL/6 mice were i.v. injected with AAV8-ALB-FOXA3 or the control virus. The mice were then fed a chow or Western diet for 16 weeks. The role of hepatic FOXA3 in energy metabolism and steatohepatitis was investigated. Plasma bile acid composition and the role of Takeda G protein-coupled receptor 5 (TGR5) in mediating the metabolic effects of FOXA3 were determined. Overexpression of hepatic FOXA3 reduced hepatic steatosis in chow-fed mice and attenuated Western diet-induced obesity and steatohepatitis. FOXA3 induced lipolysis and inhibited hepatic genes involved in bile acid uptake, resulting in elevated plasma bile acids. The beneficial effects of hepatic FOXA3 overexpression on Western diet-induced obesity and steatohepatitis were abolished in Tgr5-/- mice. Our data demonstrate that overexpression of hepatic FOXA3 prevents Western diet-induced obesity and steatohepatitis via activation of TGR5.

RESUMO

Research suggests that COVID-19-related restrictions affected individuals' ability to engage in relationship maintenance behaviors and have led to poorer romantic relationship quality. Poor relationship quality may be especially problematic for lesbian, gay, bisexual, transgender, queer or questioning, and otherwise non-heterosexual or-cisgender (LGBTQ+) college students, who often lack family support and are at greater risk for mental health issues. We used a social exchange theory lens to examine correlates of relationship satisfaction for LGBTQ+ college students during the early months of the pandemic. The analytic sample consists of 175 LGBTQ+ students (Mage = 20.5) who completed an online survey and reported being in a romantic relationship. Our findings demonstrate that LGBTQ+ students with more supportive partners were more satisfied with their relationships. These results can inform clinicians how to better support LGBTQ+ college couples when they experience relationship stress.
