To compare the psychological stress level and hair cortisol level of people living with HIV (PLWH) with those without HIV in China, a total of 220 participants were initially enrolled in the study, including 200 PLWH and 20 people living without HIV. Psychological stress level, including quality of life, anxiety, perceived stress and psychological resilience, was self-reported in both groups with related scales. The cortisol in hair was extracted and assessed by LC-APCI-MS/MS method. Propensity score matching analysis was performed to balance the baseline covariates of the two groups, whereas the difference in psychological stress level and hair cortisol level between the two groups was compared. Furthermore, the associations between psychological stress level and cortisol level were examined. Two comparison groups were matched by 1:3 propensity score matching, which yielding 20 people living without HIV and 60 PLWH. Ultimately, in regarding to the psychological stress, the levels of the anxiety (34 vs. 26, p < 0.001), perceived stress (38.5 vs. 33, p = 0.001) and psychological resilience (31 vs. 26, p = 0.004) were higher among PLWH than those living without HIV, but the people without HIV showed higher quality of life (109 vs.116, p < 0. 001). The hair cortisol level (34.66 vs. 21.61, p = 0.002) in PLWH was higher than those living without HIV. However, there were no significant associations between psychological stress level and cortisol level (p > 0.05). The PLWH showed higher level of psychological stress and cortisol than those without HIV. No relationship was seen between psychological stress level and cortisol level in PLWH.

Religious informal helpers may play a crucial role in recognizing and providing referrals to mental health professional for at-risk individuals, including those with mental illness, especially since members of religious communities tend to conceal their difficulties and to view religious leaders as a sole source of assistance. This quantitative study aimed to explore Jewish bathhouse attendants ("balaniyot") who assist women in their monthly immersion, a unique situation in which mental health symptoms (e.g.

Background: Smoking rates have declined markedly in Australia over time; however, lesbian, bisexual and queer (LBQ) women continue to smoke at higher rates than heterosexual women. Understanding the factors influencing smoking in this population is crucial for developing targeted cessation interventions and other supports.
Methods: Experiences of and motivations for smoking among 42 LBQ cisgender and transgender women and non-binary people in Australia who currently or previously smoked were explored through semi-structured interviews.

Background: Studies of salivary cortisol levels in psychosis have yielded inconsistent findings, which may be attributable to heterogeneity in cortisol measurement, illness stage, and approaches to dealing with sampling factors and potential confounders. To address these issues, we performed an individual participant data (IPD) meta-analysis comparing individuals at different stages of psychosis to controls using five different salivary cortisol measures and explored potential effect modifiers.
Methods: Salivary cortisol data from five London-based cohorts were used to derive the cortisol awakening response, total daytime cortisol output, basal cortisol, and diurnal slope measures (wake-to-evening and peak-to-evening).

The model minority stereotype (MMS) is deeply embedded within the society of the United States, including in the science, technology, engineering, and mathematics (STEM) fields. This has resulted in the neglect of STEM Asian American students' psychological needs by researchers and service providers while simultaneously pressuring the students to pursue unattainable goals. The aim of the present study was to explore the mechanism of how stress from the MMS might be related to depressive symptoms.
