Increasing a Quitline's Reach to Low-Income Tobacco Users Through 211 Agencies.

Introduction: Low-income individuals bear a disproportionate share of the burden of tobacco use. This study tested the feasibility of increasing a quitline's reach to low-income tobacco users by collaborating with 211 information and referral agencies, which primarily serve people experiencing economic hardship.

Aims And Methods: Study participants (N = 114 888) were adult tobacco users referred to the California quitline by 211 agencies, referred by healthcare clinics, or self-referred from April 17, 2021 to December 31, 2023.

Ethnicity-specific patterns of epigenetic age acceleration in rheumatoid arthritis.

Rheumatoid arthritis (RA) is an age-related chronic inflammatory disease which may include accelerated biological ageing processes in its pathogenesis. To determine if increased biological age is associated with risk of RA and/or is present once disease is established. We used DNA methylation to compare biological age (epigenetic age) of immune cells in adults at risk of RA and those with confirmed RA, including twins discordant for RA.

Impact of the XVII Pacific Games on the National Referral Hospital Emergency Department, Solomon Islands.

Background: The XVII Pacific Games was held in Honiara, Solomon Islands in 2023 and was attended by competitors from 24 Pacific nations. The National Referral Hospital (NRH) is the sole tertiary hospital and largest emergency department (ED) in the Solomon Islands, located in the capital city, Honiara, and was the designated referral hospital for the Pacific Games.

Objective: This report documents the lessons learnt from supporting a large international sporting event within a resource-limited health setting, and may help other EDs prepare for similar planned mass gatherings.

Respiratory plasticity induced by chronic hyperoxia in juvenile and adult rats.

Chronic hyperoxia during early postnatal development depresses breathing when neonatal rats are returned to room air and causes long-lasting attenuation of the hypoxic ventilatory response (HVR). In contrast, little is known about the control of breathing of juvenile or adult mammals after chronic exposure to moderate hyperoxia later in life. Therefore, Sprague-Dawley rats were exposed to 60 % O for 7 days (juveniles) or for 4 and 14 days (adults) and ventilation was measured by whole-body plethysmography immediately after the exposure or following a longer period of recovery in room air.
