Introduction: Previous research has investigated sexual orientation differences in the acoustic properties of individuals' voices, often theorizing that homosexuals of both sexes would have voice properties mirroring those of heterosexuals of the opposite sex. Findings were mixed, but many of these studies have methodological limitations including small sample sizes, use of recited passages instead of natural speech, or grouping bisexual and homosexual participants together for analyses.
Methods: To address these shortcomings, the present study examined a wide range of acoustic properties in the natural voices of 142 men and 175 women of varying sexual orientations, with sexual orientation treated as a continuous variable throughout.
Results: Homosexual men had less breathy voices (as indicated by a lower harmonics-to-noise ratio) and, contrary to our prediction, a lower voice pitch and narrower pitch range than heterosexual men. Homosexual women had lower F4 formant frequency (vocal tract resonance or so-called overtone) in overall vowel production, and rougher voices (measured via jitter and spectral tilt) than heterosexual women. For those sexual orientation differences that were statistically significant, bisexuals were in-between heterosexuals and homosexuals. No sexual orientation differences were found in formants F1-F3, cepstral peak prominence, shimmer, or speech rate in either sex.
Discussion: Recommendations for future "natural voice" investigations are outlined.

Pulmonary arterial hypertension (PAH) is a chronic progressive exacerbation of cardiopulmonary vascular disease. The patients' exercise endurance decreased progressively and the survival rate was low. Current basic therapy and targeted drug therapy can improve the quality of life (QoL) of PAH patients, but the long-term efficacy and prognosis are not good.

Human papillomavirus (HPV) vaccination could reduce HPV infection in men who have sex with men (MSM), but the published statistics on HPV vaccination uptake in MSM were scarce globally. This study estimated the uptake and profiled the service preferences of HPV vaccination of Chinese MSM in Hong Kong. Adult MSM were recruited through non-governmental organizations (NGOs) and online channels for completing an online baseline survey.

Background: How common it is with the presence of human papillomavirus (HPV) in the healthy and diseased oral cavity is largely unknown for Africans. In this cross-sectional study we assessed the prevalence of oral HPV and the risk factors associated with HPV contraction including sexual practice in the urban and rural Zambian population.
Methods: Urban (N = 188) and rural (N = 211) Zambian adults aged 21 years and older living in Ndola and Mansa, respectively, were interviewed about demographical data, oral and coital sexual history and tobacco and alcohol use.

Background: Sexual orientation and gender identity (SOGI) impact health, yet healthcare providers often lack the necessary education to address the unique needs of the 2SLGBTQIA+ community. The SOGI Nursing Toolkit was developed to enhance cultural humility among healthcare providers using virtual simulation experiences.
Objective: The purpose of this study was to explore nurse educators' experiences with debriefing virtual simulations related to the SOGI nursing toolkit within nursing education.

Aims: The study investigated relationships between how youth and young adults access alcohol and their binge drinking behaviors.
Methods: Data from the Rhode Island Student Survey (11- to 18-year-olds) and the Mobile Screen Time project (18- to 24-year-old) were included. Participants were asked whether they access alcohol through several different methods (e.
