OBJECTIVE Depression and anxiety symptoms are commonly observed among clinical populations, especially among women and maltreated individuals. Few investigations have, however, assessed the existence of distinct symptoms trajectories among clinical populations and how these relate to childhood maltreatment, sex differences, and stress physiology indexed by hair cortisol concentrations (HCC). The current study (1) identified distinct depression and anxious trajectories in a sample of psychiatric inpatients followed-up prospectively from their admission to a psychiatric emergency service (PES), and (2) examined whether HCC, childhood maltreatment and sex independently and jointly predict these trajectories. METHODS Adult inpatients (N = 402, 55% women) were recruited upon admission to PES (T1) during which HCC (reflecting cortisol secretion for the last 3 months), childhood maltreatment, and depression and anxiety symptoms were assessed. Symptoms were re-evaluated when patients were discharged from the hospital (T2), admitted to outpatient clinics (T3), and 12 months later or at the end of outpatient treatment (T4). RESULTS Three trajectories were identified for depression and anxiety symptoms. Among men, higher HCC predicted higher odds of evincing chronic depressive symptoms compared to a Low Stable trajectory (OR 3.46, 95% confidence interval [CI] 1.43-8.40). Greater childhood maltreatment among men predicted higher chances of exhibiting chronic anxious symptoms than the Low Stable (OR 1.47, 95% CI 1.07-2.02) and the High Decreasing trajectories (OR .70, 95% CI .51-.95). Opposite findings were noted for women. CONCLUSIONS Childhood maltreatment and HCC should be further investigated as predictors of anxious and depressive trajectories, during which sex-specific associations ought to be considered.

OBJECTIVE: We examined individual differences in CD4/CD8 T-cell ratio trajectories and associated risk profiles from acute HIV infection (AHI) through 144 weeks of antiretroviral therapy (ART) using a data-driven approach. METHODS: A total of 483 AHI participants began ART during Fiebig I-V and completed follow-up evaluations for 144 weeks. CD4+, CD8+, and CD4/CD8 T-cell ratio trajectories were defined followed by analyses to identify associated risk variables. RESULTS: Participants had a median viral load (VL) of 5.88 copies/ml and CD4/CD8 T-cell ratio of 0.71 at enrollment. After 144 weeks of ART, the median CD4/CD8 T-cell ratio was 1.3. Longitudinal models revealed five CD4/CD8 T-cell ratio subgroups: group 1 (3%) exhibited a ratio >1.0 at all visits; groups 2 (18%) and 3 (29%) exhibited inversion at enrollment, with normalization 4 and 12 weeks after ART, respectively; and groups 4 (31%) and 5 (18%) experienced CD4/CD8 T-cell ratio inversion due to slow CD4+ T-cell recovery (group 4) or high CD8+ T-cell count (group 5). Persistent inversion corresponded to ART onset after Fiebig II, higher VL, soluble CD27 and TIM-3, and lower eosinophil count. Individuals with slow CD4+ T-cell recovery exhibited higher VL, lower white blood cell count, lower basophil percent, and treatment with standard ART, as well as worse mental health and cognition, compared with individuals with high CD8+ T-cell count. CONCLUSIONS: Early HIV disease dynamics predict unfavorable CD4/CD8 T-cell ratio outcomes after ART. CD4+ and CD8+ T-cell trajectories contribute to inversion risk and correspond to specific viral, immune, and psychological profiles during AHI. Adjunctive strategies to achieve immune normalization merit consideration.

ObjectivesBeyond male/female binaries, gender roles represent masculine and feminine traits that we assimilate and enact throughout life span development. Bem proposed that “androgynous” individuals adeptly adapt to different contexts by alternating from a strong repertoire of both masculine and feminine gender roles. By contrast, “undifferentiated” individuals may not adapt as well to social norms because of weak self-endorsed masculinity and femininity.MethodsAmong 204 adults (mean [standard error] age = 40.4 [0.9] years; 70% women) working in a psychiatric hospital, we hypothesized that androgynous individuals would present better mental health and less physiological dysregulations known as allostatic load (AL) than undifferentiated individuals. AL was indexed using 20 biomarkers using the conventional “all-inclusive” formulation that ascribes cutoffs without regard for sex or an alternative “sex-specific” formulation with cutoffs tailored for each sex separately while controlling for sex hormones (testosterone, estradiol, progesterone). Well-validated questionnaires were used.ResultsIndependent of sex, androgynous individuals experienced higher self-esteem and well-being and lower depressive symptoms than did undifferentiated individuals. Men manifested higher AL than did women using the all-inclusive AL index (p = .044, η2P = 0.025). By contrast, the sex-specific AL algorithm unmasked a sex by gender roles interaction for AL (p = .043, η2P = 0.048): with the highest AL levels in undifferentiated men. Analysis using a gender index based on seven gendered constructs revealed that a greater propensity toward feminine characteristics correlated only with elevated sex-specific AL (r = 0.163, p = .025).ConclusionsBeyond providing psychobiological evidence for Bem's theory, this study highlights how sex-specific AL formulations detect the effects of sociocultural gender. published

Objectives: Lesbian, gay, and bisexual (LGB) individualsVparticularly those who have not disclosed their sexual orientationVare believed to experience increased chronic stress in comparison with heterosexuals. This interdisciplinary study assessed whether psychiatric symptoms (self-rated anxiety, depression, and burnout), stress hormone profiles (diurnal cortisol), and physiological dysregulations (allostatic load [AL]) would differ for a) LGBs versus heterosexuals and b) disclosed LGBs versus nondisclosed LGBs. Methods: The study included 87 healthy participants (mean [SD] age = 24.6 [0.6] years; LGB n = 46, 43% women; and heterosexual n = 41, 49% women). Diurnal cortisol sampled at five time points was averaged for 2 days. AL indices were based on an algorithm incorporating 21 biomarkers representing neuroendocrine, immune/inflammatory, metabolic, and cardiovascular functioning. Psychological measures were assessed with well-validated questionnaires. Results: Between-group results revealed no significant differences in symptoms of anxiety and burnout, nor among diurnal cortisol levels between sexual orientations. By contrast, gay/bisexual men unexpectedly had lower depressive symptoms (p = .003) and AL levels (p = .043) compared with heterosexual men. Within-group results revealed that disclosed LGBs had fewer psychiatric symptoms (p values G 0.01) and lower cortisol levels +30 minutes upon awakening (p = .004) compared with nondisclosed LGBs. Disclosure was not significantly related to AL levels. Conclusions: LGBs did not manifest more stress-related problems than did heterosexuals. Life transitions like disclosing to one’s family and friends may be protective against psychopathologies and hyperactive cortisol awakening responses. Our novel findings underline the roles disclosure processes have on positive health and well-being for sexual minorities.
