The UCLA Loneliness Scale (Version 3; UCLA-LSV3) is widely used for assessing loneliness. Nevertheless, the validity of this scale for assessing loneliness in individuals with schizophrenia or schizoaffective disorder has not been determined. Additionally, studies validating the eight-item and three-item versions of UCLA-LSV3 have not included individuals with severe mental illness; therefore, whether the short versions are comparable to the full 20-item version of UCLA-LSV3 for this population is unclear.

This study aimed to compare the level of attitudes toward homosexuality among nurses in Taiwan between 2005 and 2017 and with various demographic characteristics, as well as the roles of demographic characteristics in the changing trend of attitudes toward homosexuality between 2005 and 2017. This survey study recruited nurses from three hospitals in 2005 (Survey 2005, = 1176) and 2017 (Survey 2017, = 1519). Participants' four dimensions of attitudes toward homosexuality, including condemnation, immorality, avoiding contact, and stereotypes, were assessed using the Taiwanese version of the Attitudes Toward Homosexuality Questionnaire.

Methods: In 63 women with PMDD and 53 healthy controls, we prospectively evaluated serum levels of leptin and ghrelin, Body Mass Index(BMI), and self-reported sweet cravings, cognitive restraint, uncontrolled eating, emotional eating, depression, and impulsivity during the early luteal (EL) and late luteal (LL) phases.
Results: Compared with the controls, the women with PMDD had higher BMI, higher leptin concentrations in the EL and LL phase, and leptin concentrations increased from the EL to the LL phase.

Objective/introduction: The dynamics of ovarian hormone fluctuations during the luteal phase of the menstruation cycle were previously suggested to contribute to the development of premenstrual dysphoric disorder (PMDD) symptoms, but adequate empirical evidence has not been obtained from hormone concentration studies. We prospectively evaluated estrogen and progesterone levels in the early luteal (EL) and late luteal (LL) phases in women with PMDD and the association of these levels with PMDD symptom severity. Methods: 63 women with PMDD and 53 controls without such severe symptoms were evaluated for the estrogen and progesterone levels, and PMDD severity in the EL and LL phases.

Neurophysiological studies have found a higher high-beta activity of electroencephalography (EEG) at the posterior cortex among patients with comorbid MDD and anxiety symptoms. The present study examined the effects of ALAY and high-beta down-training (Beta) neurofeedback in symptoms of depression and anxiety and EEG parameters.
