Purpose: to verify if teachers with less vocal use due to reduced workload have fewer complaints of vocal disorders and better environmental and organizational working conditions.
Methods: 46 teachers of both genders, with a mean age of 39.5 years old, and 15 years of career length participated in this study. The individuals were divided into group A, public school teachers with exclusive dedication to a single school and regulated workload; group B, public school teachers with elevated workload working in many schools. All subjects were submitted to the following instruments: Condition of Vocal Production-Teacher and the Screening Index for Voice Disorder.
Results: group B teachers presented voice disorder (5.21; p=0.02) and greater complaints regarding acoustic conditions (p=0.04), temperature (p=0,04), humidity (p=0.01), lighting (p=0.001), cleanliness (p=0.01), and didactic materials (p<0.0001). Habits of screaming (p=0.02), speaking in an open place (p=0,02), and vocal orientations (p=0.01) also had a statistically significant difference.
Conclusion: Teachers working in elementary and high school belonging to the group of exclusive dedication to a single school, with reduced weekly classroom hours and less vocal exposure had fewer complaints of voice disorders, better environmental and organizational conditions, and reported screaming less at work.

The changing relationship between racial identity and skin color in Brazil.
Proc Natl Acad Sci U S A
January 2025
Department of Sociology, University of California, Irvine, CA 92697-5100.
In recent years, Brazil's non-White (Brown and Black) population became a numerical majority for the first time since the 19th century. Although we know this change was mostly due to racial reclassification, we do not know how such changes are related to skin color, the primary marker of race in Brazil. Using data from six Latin American Public Opinion Project (LAPOP), or America's Barometer, surveys from 2010 to 2023, we examine how changes in racial self-identification (White, Brown, or Black) are related to respondent skin color (light, medium, or dark).

Affordable and clean energy, eliminating poverty, and reducing inequality are important goals of the United Nations Sustainable Development Goals (SDGs). This paper examines the role of access to clean cooking fuels in promoting income growth and reducing income inequality. Using data from Chinese households, we show that a 10% increase in the adoption of clean cooking fuels would result in an increase in total annual household income of US$37 billion nationwide.

Cultural Adaptation of an Aboriginal and Torres Strait Islanders Maternal and Child mHealth Intervention: Protocol for a Co-Design and Adaptation Research Study.
JMIR Res Protoc

College of Medicine and Public Health, Flinders University, Bedford Park, Australia.
Background: There is limited evidence of high-quality, accessible, culturally safe, and effective digital health interventions for Indigenous mothers and babies. Like any other intervention, the feasibility and efficacy of digital health interventions depend on how well they are co-designed with Indigenous communities and their adaptability to intracultural diversity.
Objective: This study aims to adapt an existing co-designed mobile health (mHealth) intervention app with health professionals and Aboriginal and/or Torres Strait Islander mothers living in South Australia.
Baseline characteristics and 2-year functional outcome data of patients undergoing an arthroscopic rotator cuff repair in Switzerland, results of the ARCR_Pred study.

Orthopaedic Surgery and Traumatology, University Hospital Basel, Basel, Switzerland.
The ARCR_Pred study was initiated to document and predict the safety and effectiveness of arthroscopic rotator cuff repair (ARCR) in a representative Swiss patient cohort. In the present manuscript, we aimed to describe the overall and baseline characteristics of the study, report on functional outcome data and explore case-mix adjustment and differences between public and private hospitals. Between June 2020 and November 2021, primary ARCR patients were prospectively enrolled in a multicenter cohort across 18 Swiss and one German orthopedic center.
