Effect of laparoscopic handle size on surgical performance: A randomized crossover trial.

Laparoscopic instrument handles design and dimensions are crucial to determine the configuration of surgeons' hand grip and, therefore, can have a deleterious effect on overall surgical efficiency and surgeons' comfort. The aim of this study is to investigate the impact of laparoscopic handle size and hand surface area on surgical task performance. A single-blind, randomized crossover trial was carried out with 29 novice medical students.

Health inequalities in Brazilian adolescents: Measuring and mapping gaps in a cross-sectional school-based survey.

Background And Aims: This study aims to describe inequalities in health indicators according to gender, area of residence, and socioeconomic position among Brazilian adolescents.

Methods: Cross-sectional study using data from a school-based survey carried out in Brazil in 2019. Twelve health outcomes were evaluated.

Satisfaction of Health Professionals Regarding the Short Binasal Prong Used as a Non-Invasive Ventilation Interface in Neonatology.

Purpose: To evaluate the health professionals' satisfaction regarding the short binasal prong used in Neonatal Intensive Care Units (NICU), evaluate the difficulties related to its use, and present possible improvements in the design of this device.

Patients And Methods: Observational, cross-sectional study with prospective data collection carried out in the NICU of a public hospital in southern Brazil. This research was presented into two stages.

Thermal changes in the sacral region with different mattresses used in the prevention of pressure injuries.

Background: Pressure Injury (PI) is a severe health problem that affects millions of people. As a preventive strategy for high-risk ICU patients, the appropriate selection of a support surface is essential for preventing PI, along with risk assessment and repositioning. Increasing skin temperature has been associated with a higher susceptibility to PI development.

Effects of hydrotherapy and tactile-kinesthetic stimulation on weight gain of preterm infants admitted in the Neonatal Intensive Care Unit.

Objective: The present study aimed to evaluate the effects of hydrotherapy and tactile-kinesthetic stimulation on the birth weight of preterm infants admitted in the Neonatal Intensive Care Unit.

Method: It was a randomized controlled trial, without blinding, in which 44 preterm infants of both sexes with gestational age between 32 and 34 weeks were included into two groups: hydrotherapy group (n = = 22) and tactile-kinesthetic stimulation group (n = 22). Weight gain was the parameter assessed daily.

Correlation of End-Tidal Carbon Dioxide with Arterial Carbon Dioxide in Mechanically Ventilated Neonates: A Scoping Review.

Monitoring CO levels in intubated neonates is highly relevant in the face of complications associated with altered CO levels. Thus, this review aims to present the scientific evidence in the literature regarding the correlation between arterial carbon dioxide measured by non-invasive methods in newborns submitted to invasive mechanical ventilation. The search was carried out from January 2020 to January 2021, in the Scopus, Medline, The Cochrane Library, Web of Science, CINAHL and Embase databases.

Investigation of musculoskeletal symptoms in a manufacturing company in Brazil: a cross-sectional study.

Background: Musculoskeletal disorders are prevalent and represent the most common health problem among the working population in industrially-developing countries, with considerable costs and impact on quality of life. Despite the high incidence of disability insurance claims among Brazilian manufacturing-sector workers, only a few studies assessed musculoskeletal disorders prevalence.

Objective: To provide information on the prevalence of musculoskeletal disorders among manufacturing-sector workers and to explore the relationship between musculoskeletal disorders and sociodemographic and occupational characteristics in a medium metallurgical company located in Brazil.

Parachuting harnesses comparative evaluation on energy distribution grids.

This research aims to make a comparative evaluation of three different parachuting harnesses to work at heights in the energy industry, from the electricians' point of view concerning these products under the optics of usability and ergonomic principles, and mainly justified by the high quantity of injuries at the energy industry due to high falls. According to its main target, this field research is classified as exploratory-descriptive transversal viewing study and, considering this perspective, the study was developed in four steps. Research results have enlightened the weakest spots and the potential improvement opportunities of these products, developed to assure safety of the work at heights to the energy industry, according to the opinion of the users.
