Tactile breathing guidance increases oxygen saturation but not alertness or hypoxia symptoms.

We investigated the effect of tactile guided slow deep breathing compared with that of spontaneous breathing on blood oxygen saturation (SpO2), alertness, and hypoxia symptoms during acute hypobaric hypoxia. We also evaluated the usability of this tactile breathing guidance. Twelve male military pilots were exposed to a simulated altitude of 4,572 m (15,000 ft) in a repeated measures study while breathing spontaneously and during tactile guided slow deep breathing.

Hypoxia impairs reaction time but not response accuracy in a visual choice reaction task.

We investigated the effect of hypoxia on the reaction time (RT) and response accuracy of pilots performing a visual choice reaction task that corresponded to the scanning of helmet mounted display (HMD) symbology. Eighteen male military pilots performed the task in a hypobaric chamber at two simulated altitudes (92 m and 4572 m) in a single-blinded repeated measures and counter-balanced design. The visual stimuli were displayed in low and high contrast and at a 30- and 50-degree field of view (FoV).

Working conditions in women with multiple pregnancy-the impact on preterm birth and adherence to guidelines: a prospective cohort study.

Background: Women with multiple pregnancies are at risk for maternal complications such as preterm birth. Hazardous working conditions, such as physically demanding work and long and irregular working hours, might increase the risk of preterm birth.

Objective: This study primarily aimed to determine whether certain working conditions up to 20 weeks of pregnancy increase the risk of preterm birth in multiple pregnancies.

Views of breast cancer survivors on work participation guidance by general practitioners: a qualitative study.

Background: Breast cancer survivors can be at high risk of having work-related problems. Previous studies suggest that GPs could discuss work participation with cancer patients and provide guidance. The aim this study is to explore the experiences and expectations of breast cancer survivors with their GPs' role regarding guidance on work participation and return to work.

The role of general practitioners in the work guidance of cancer patients: views of general practitioners and occupational physicians.

Purpose: To explore views of general practitioners (GPs) and occupational physicians (OPs) on the role of GPs in work guidance of cancer patients.

Methods: Between 2016 and 2019, two focus groups with GPs (N = 17) and two focus groups with OPs (N = 10) were conducted. Focus group discussions were audiotaped and transcribed verbatim.
