Background Preliminary empirical data indicates a substantial impact of the COVID-19 pandemic on well-being and mental health. Individuals with minoritized sexual and gender identities are at a higher risk of experiencing such negative changes in their well-being. The objective of this study was to compare levels of well-being among cis-heterosexual individuals and individuals with minoritized sexual and gender identities during the COVID-19 pandemic. Methods Using data obtained in a cross-sectional online survey between April 20 to July 20, 2020 (N = 2332), we compared levels of well-being (WHO-5) across subgroups (cis-individuals with minoritized sexual identities, individuals with minoritized gender identities and cis-heterosexual individuals) applying univariate (two-sample t-test) and multivariate analysis (multivariate linear regression). Results Results indicate overall lower levels of well-being as well as lower levels of well-being in minoritized sexual or gender identities compared to cis-heterosexual individuals. Further, multivariate analyses revealed that living in urban communities as well as being in a relationship were positively associated with higher levels of well-being. Furthermore, a moderation analysis showed that being in a relationship reduces the difference between groups in terms of well-being. Conclusion Access to mental healthcare for individuals with minoritized sexual and gender identities as well as access to gender-affirming resources should be strengthened during COVID-19 pandemic. Healthcare services with low barriers of access such as telehealth and online peer support groups should be made available, especially for vulnerable groups.
The aim of this study was to assess the prognostic value of the steroid hormone receptor expression, counting the retinoid X receptor (RXR) and thyroid hormone receptors (THRs), on the two different breast cancer (BC) entities: multifocal/multicentric versus unifocal. The overall and disease-free survival were considered as the prognosis determining aspects and analyzed by uni- and multi-variate analysis. Furthermore, histopathological grading and TNM staging (T = tumor size, N = lymph node involvement, M = distant metastasis) were examined in relation to RXR and THRs expression. A retrospective statistical analysis was carried out on survival-related events in a series of 319 sporadic BC patients treated at the Department of Gynecology and Obstetrics at the Ludwig-Maximillian’s University in Munich between 2000 and 2002. The expression of RXR and THRs, including its two major isoforms THRα1 and THRα2, was analyzed by immunohistochemistry and showed to have a significant correlation for both BC entities in regard to survival analysis. Patients with multifocal/multicentric BC were exposed to a significantly worse disease-free survival (DFS) when expressing RXR. Patients with unifocal BC showed a significantly worse DFS when expressing THRα1. In contrast, a statistically significant positive association between THRα2 expression and enhanced DFS in multifocal/multicentric BC was shown. Especially the RXR expression in multifocal/multicentric BC was found to play a remarkably contradictory role for BC prognosis. The findings imply the need for a critical review of possible molecular therapies targeting steroid hormone receptors in BC treatment. Our results strengthen the need to further investigate the behavior of the nuclear receptor family, especially in relation to BC focality.
Ischemia reperfusion injury (IRI) of the kidney results in interferon regulatory factor 4 (IRF4)–mediated counter-regulation of the acute inflammatory response. Beyond that, IRF4 exerts important functions in controlling the cytokine milieu, T-cell differentiation, and macrophage polarization. The latter has been implicated in tissue remodeling. It therefore remains elusive what the role of IRF4 is in terms of long-term outcome following IRI. We hypothesized that an inability to resolve chronic inflammation in Irf4−/− mice would promote chronic kidney disease (CKD) progression. To evaluate the effects of IRF4 in chronic upon acute injury in vivo, a mouse model of chronic injury following acute IRI was employed. The expression of Irf4 increased within 10 days after IRI in renal tissue. Both mRNA and protein levels remained high up to 5 weeks upon IRI, suggesting a regulatory function in the chronic phase. Mice deficient in IRF4 display increased tubular cell loss and defective clearance of infiltrating macrophages. These phenomena were associated with increased expression of pro-inflammatory macrophage markers together with reduced expression of alternatively activated macrophage markers. In addition, IRF4-deficient mice showed defective development of alternatively activated macrophages. Hints of a residual M1 macrophage signature were further observed in human biopsy specimens of patients with hypertensive nephropathy vs. living donor specimens. Thus, IRF4 restricts CKD progression and kidney fibrosis following IRI, potentially by enabling M2 macrophage polarization and restricting a Th1 cytokine response. Deteriorated alternative macrophage subpopulations in Irf4−/− mice provoke chronic intrarenal inflammation, tubular epithelial cell loss, and renal fibrosis in the long course after IRI in mice. The clinical significance of these finding for human CKD remains uncertain at present and warrants further studies.
Introduction:The COVID-19 pandemic drastically altered the way of life around the world. Due to social distancing measures, contact restrictions and fears of infection, social life has changed significantly. These measures along with the stressors associated with the current worldwide situation, will inevitably have an effect on people's interpersonal and personal behaviors. Aim: This study evaluates the effect the COVID-19 pandemic and nationwide German lockdown had on the sexual behavior of cis men. Methods: An anonymous nationwide web-based questionnaire was conducted among cis men in Germany during the first COVID-19 home isolation (April 20, 2020−July 20, 2020. The questionnaire was distributed via e-mail, online chats and social-media platforms. Main Outcome Measures: Data was collected on general characteristics including demographics and socio-economic backgrounds. To evaluate sexual health, questions from the Sexual Behavior Questionnaire were included. Results: 523 cis male participated. 414 met the inclusion criteria. Most were heterosexual (n = 248, 59.9%; vs homosexual n = 97, 23.4%; vs bisexual n = 69, 16.7%). 243 (59%) were employed, 153 (37.1%) were students and 16 (3.9%) were unemployed. Most of the participants reported an annual income lower than 75.000€. During the lockdown, average weekly frequency of sexual intercourse and masturbation was increased in all groups. Consistently, a significant rise of higher satisfaction with the frequency of sexual contacts during the quarantine was observed (P < .05). Furthermore, the level of sexual arousal increased significantly in all groups (P < .0005). Capability to enjoy sexual intercourse or masturbation increased significantly in heterosexual (P < .0005) and homosexual men (P < .005). Bisexual participants showed a significant increase in general satisfaction with sexual life (P < .05) and a significant decrease in satisfaction in relationship or single life (P < .05). Positive confounders in the changing of sexual behavior during the COVID-19 pandemic were: Being in a relationship or being single, parenthood and being employed. Conclusion: Our study firstly describes how COVID-19 pandemic related restrictions and social distancing measurements altered sexual behavior amongst cis male in Germany. Further studies, including sexual minorities specifically, are needed to clarify if the behavior in the first German nationwide quarantine has persisted or transformed as the pandemic proceeded.
