Exploring the well-being of professional female musicians: a self-determination theory perspective.

Background: This study investigated the well-being of 16 professional female musicians through the lens of Self-Determination Theory, focusing on the satisfaction of their psychological needs for autonomy, competence, and relatedness, as well as the unique challenges they encounter in their careers.

Methods: Semi-structured interviews were undertaken and analyzed using thematic analysis.

Results And Discussion: Three broad themes and 10 sub-themes emerged from the interviews.

The co-occurrence of multimorbidity and polypharmacy among middle-aged and older adults in Canada: A cross-sectional study using the Canadian Longitudinal Study on Aging (CLSA) and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

Background: There is an increasing prevalence of multiple conditions (multimorbidity) and multiple medications (polypharmacy) across many populations. Previous literature has focused on the prevalence and impact of these health states separately, but there is a need to better understand their co-occurrence.

Methods And Findings: This study reported on multimorbidity and polypharmacy among middle-aged and older adults in two national datasets: the Canadian Longitudinal Study on Aging (CLSA) and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

New evidence for baroreflex and respiratory chemoreflex mediated cerebral sympathetic activation in humans.

The brain is highly innervated by sympathetic nerve fibres; however, their physiological purpose is poorly understood. We hypothesized that unilateral cerebral norepinephrine (NE) spillover, an index of cerebral sympathetic nerve activity (SNA), would be elevated when engaging the baroreflex [via lower-body negative pressure (LBNP; -20 and -40 Torr)] and respiratory chemoreflexes [via carbon dioxide (CO) administration (+8 Torr)], independently, and in combination. Twelve young and healthy participants (5 females) underwent simultaneous blood sampling from the right radial artery and internal jugular vein.

Low dose contrast enhancement of biodegradable low-density stents by an approach balancing radiopaque coatings and beam filtration.

Biodegradable cardiovascular stents made of thin, low atomic number metals (e.g. Zn, Mg, Fe) are now approved for clinical use.

Low Back Pain During and After Spaceflight: A Systematic Review with Meta-Analysis.

Space flights can produce physiological changes in the spine, leading to the development of acute and chronic pain in passengers. However, there is a lack of comprehensive literature exploring physiological spine changes and acute and chronic pain in space passengers (astronauts and animals). The first aim of this study was to identify the physiological changes experienced by passengers (humans and animals) after space flight.
