Discrimination, resilience, and HIV testing frequency among black women seeking services from STD clinics.

Rationale: In the United States, Black women are disproportionately affected by HIV, accounting for most new HIV infections diagnosed among women. Socio-structural barriers to HIV testing include stigma and discrimination but may be mitigated by resilience.

Objective: We aimed to examine the effect of discrimination and resilience on HIV testing behaviors among Black women.

The Utility of Scatter Feeding as Enrichment: Do Broiler Chickens Engage with Scatter-Fed Items?

In recent years, welfare certification companies have encouraged the use of scatter feeding as enrichment material, though there is little scientific evidence to support a scatter feeding program. This study aimed to understand the impact of scatter feeding on the foraging behavior of broilers. One hundred eighty Ross 308 chicks were allocated into six treatment groups (six replicates/treatment).

Racial and Ethnic Differences in COVID-19 Outcomes, Stressors, Fear, and Prevention Behaviors Among US Women: Web-Based Cross-sectional Study.

Background: In the United States, racial and ethnic minorities are disproportionately affected by COVID-19, with persistent social and structural factors contributing to these disparities. At the intersection of race/ethnicity and gender, women of color may be disadvantaged in terms of COVID-19 outcomes due to their role as essential workers, their higher prevalence of pre-existing conditions, their increased stress and anxiety from the loss of wages and caregiving, and domestic violence.

Objective: The purpose of this study is to examine racial and ethnic differences in the prevalence of COVID-19 outcomes, stressors, fear, and prevention behaviors among adult women residing in the United States.

"It makes such a difference": An examination of how LGBTQ youth talk about personal gender pronouns.

Background And Purpose: The World Health Organization has developed standards for youth-friendly health services to support adolescents and encourage health care utilization among youth. Necessary building blocks for youth-friendly care include strong interpersonal relationships between youth and health care providers. Nurse practitioners (NPs) may be particularly well positioned to form these relationships.

Perceptions of Sexual Orientation and Gender Identity Minority Adolescents About Labels.

Young peoples' acceptance and use of nontraditional, descriptive identity labels (e.g., pansexual, genderqueer) require nurses to consider moving beyond use of traditional terms (e.

Light at Night and Measures of Alertness and Performance: Implications for Shift Workers.

Rotating-shift workers, particularly those working at night, are likely to experience sleepiness, decreased productivity, and impaired safety while on the job. Light at night has been shown to have acute alerting effects, reduce sleepiness, and improve performance. However, light at night can also suppress melatonin and induce circadian disruption, both of which have been linked to increased health risks.

Daytime light exposure: effects on biomarkers, measures of alertness, and performance.

Light can elicit an alerting response in humans, independent from acute melatonin suppression. Recent studies have shown that red light significantly increases daytime and nighttime alertness. The main goal of the present study was to further investigate the effects of daytime light exposure on performance, biomarkers and measures of alertness.

Light level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression.

Exposure to light from self-luminous displays may be linked to increased risk for sleep disorders because these devices emit optical radiation at short wavelengths, close to the peak sensitivity of melatonin suppression. Thirteen participants experienced three experimental conditions in a within-subjects design to investigate the impact of self-luminous tablet displays on nocturnal melatonin suppression: 1) tablets-only set to the highest brightness, 2) tablets viewed through clear-lens goggles equipped with blue light-emitting diodes that provided 40 lux of 470-nm light at the cornea, and 3) tablets viewed through orange-tinted glasses (dark control; optical radiation <525 nm ≈ 0). Melatonin suppressions after 1-h and 2-h exposures to tablets viewed with the blue light were significantly greater than zero.

The impact of light from computer monitors on melatonin levels in college students.

Objectives: Self-luminous electronic devices emit optical radiation at short wavelengths, close to the peak sensitivity of melatonin suppression. Melatonin suppression resulting from exposure to light at night has been linked to increased risk for diseases. The impact of luminous cathode ray tube (CRT) computer monitors on melatonin suppression was investigated.
