The estrogen protection hypothesis of schizophrenia was introduced in the late 1980s to explain gender-related differences in epidemiology and clinical features. This study examines whether raloxifene, an estrogen agonist, might be effective as antipsychotic augmentation for ameliorating schizophrenia symptoms in women.

To identify the COVID-19 pandemic impact on well-being/mental health, coping strategies, and risk factors in adolescents worldwide. This study was based on an anonymous online multi-national/multi-language survey in the general population (representative/weighted non-representative samples, 14-17 years of age), measuring change in well-being (World Health Organization-Five Well-Being Index [WHO-5]/range = 0-100) and psychopathology (validated composite P-score/range = 0-100), WHO-5 <50 and <29, pre- vs during COVID-19 pandemic (April 26, 2020-June 26, 2022). Coping strategies and 9 a priori- defined individual/cumulative risk factors were measured. A χ², penalized cubic splines, linear regression, and correlation analyses were conducted. Analyzing 8,115 of 8,762 initiated surveys (representative = 75.1%), the pre-pandemic WHO-5 and P-score remained stable during the study (excluding relevant recall bias/drift), but worsened during the pandemic by 5.55 ± 17.13 (SD) and 6.74 ± 16.06 points, respectively (effect size d = 0.27 and d = 0.28). The proportion of adolescents with WHO-5 scores suggesting depression screening (<50) and major depression (2 years. The 3 most subjectively effective coping strategies were Internet use, exercise/walking, and social contacts. Overall, well-being/mental health worsened (small effect sizes) during the early stages of the COVID-19 pandemic, especially in vulnerable subpopulations. Identified at-risk groups, association with pandemic-related measures, and coping strategies can inform individual behaviors and global public health strategies. The impact of COVID-19 and related restrictions on the mental health of children and adolescents remains unclear. This study conducted an anonymous online survey with over 8,100 adolescents aged 14 to 17 years worldwide. Results showed a significant decline in wellbeing, with depression rates increasing from 9% to 17% returning to near- pre-pandemic values after about 2 years. Adolescents with preexisting mental health conditions, female youth, and those affected by school closures were particularly vulnerable. Effective coping strategies included internet use, exercise, and social contacts, highlighting areas for public health focus to support youth during pandemics.

Introduction: APOE is one of the prominent genes involved in the increased risk of developing Alzheimer’s disease, but its effect on cognition in patients who are not yet diagnosed with dementia or mild cognitive impairment is relatively understudied. We aimed to examine the effect of ApoE4 on cognitive performance in unimpaired middle-aged and elderly persons. Materials and methods: Our study included 51 cognitively unimpaired participants divided into ApoE4 positive patients and controls by APOE genotyping. The following clinical and demographic characteristics were collected: age, gender, education, social status, BMI, history of medical or psychiatric disorders. Patients with current anxiety or depressive disorders were excluded. Cognitive function was evaluated using MMSE, Rey Auditory-Verbal Learning Test, Rey Complex Figure test, TMT A and B and verbal fluency test. The two groups were matched for age, sex, and education. Categorial data was analyzed using Chi-Square and continuous data using Student-T test (parametric variables) or Mann-Whitney test (non-parametric variables). Statistical significance was considered at p≤.05. Results: There were 11 (21.6%) ApoE4 positive patients and 40 (78.4%) controls. There were no significant differences between the groups regarding socio-demographic and clinical characteristics. The ApoE4 positive group performed slightly worse on cognitive evaluations compared to controls but only the mean scores of the Rey Complex Figure Test – Memory reached statistical significance (p=.019). Conclusion: Cognitive evaluation generally rendered lower scores in the ApoE4 group compared to the control group. However, only visual memory impairment scores were significantly lower in the ApoE4 positive individuals than in controls.
