Abdominal Myosteatosis and Cognitive Decline in a Biracial Cohort: Insights from CARDIA Study.

Objective: Skeletal muscle fat infiltration (myosteatosis) increases with age and is an emerging risk factor for dementia. We aimed to determine the association between myosteatosis and cognitive decline among middle-aged White and Black Americans.

Methods: Data were on men (n=1,080; 41.

The inclusion and consideration of cultural differences and health inequalities in physical activity behaviour in the UK - the impact of guidelines and initiatives.

Despite widespread attempts from governments and leading health organisations worldwide to promote equity in healthy living medicine, the evidence suggests that attempts to curb worsening public health have been almost entirely ineffective. Despite significant advancements in knowledge, medicine, and technology, as well as the promotion of guidelines and the implementation of numerous global initiatives aimed at addressing health disparities and mitigating the progression of non-communicable diseases (NCDs) worldwide, substantial work remains to be undertaken particularly in addressing inequalities in physical activity. Achieving equitable access to health resources and parity in health outcomes remains a critical and unresolved challenge.

Impact of under-assisted ventilation on diaphragm function and structure in a porcine model.

Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

Acute selective serotonin-reuptake inhibition elevates basal ventilation, attenuates the rebreathing ventilatory response, independent of cerebral perfusion.

Serotonin (5-HT) is integral to signalling in areas of the brainstem controlling ventilation and is involved in central chemoreception. Selective serotonin reuptake inhibitors (SSRIs), used to effectively increase 5-HT concentrations, are commonly prescribed for depression. The effects of SSRIs on the control of breathing and the potential influence of cerebral blood flow (CBF) have not been directly assessed.
