"Atlanta Is Like Wakanda… but With Real Big, Big Issues": A Focus Group Study of Community Strengths and Health Issues in Diverse Groups in Atlanta, Georgia.

Background And Objectives: This qualitative study explored perceived community strengths and health issues among 3 underserved and under-studied populations in the Atlanta, Georgia-older adults, Black or African American persons, and refugees/immigrants/migrants.

Methods: Eight focus groups were conducted with 92 participants who were members of the 3 populations in Atlanta between November 2022 and March 2023.

Results: Although there were variations among groups, all groups emphasized diversity within their community as the foundation of community strength.

Evaluation of a Virtual Health Hub for People Experiencing Homelessness in Sydney, Australia: Ensuring Physical and Psychological Primary Health Care in Crisis Accommodation.

Introduction: Individuals experiencing homelessness have higher rates of chronic disease and face challenges accessing primary care. Virtual health care can reduce health inequity but needs user acceptance. A virtual health hub (VHH) for people experiencing homelessness in Sydney provided virtual GP and psychologist care within a crisis accommodation service.

Identifying the Brain Circuits that Regulate Pain-Induced Sleep Disturbances.

Unlabelled: Pain therapies that alleviate both pain and sleep disturbances may be the most effective for pain relief, as both chronic pain and sleep loss render the opioidergic system, targeted by opioids, less sensitive and effective for analgesia. Therefore, we first studied the link between sleep disturbances and the activation of nociceptors in two acute pain models. Activation of nociceptors in both acute inflammatory (AIP) and opto-pain models led to sleep loss, decreased sleep spindle density, and increased sleep fragmentation that lasted 3 to 6 hours.

Lateral parabrachial FoxP2 neurons regulate respiratory responses to hypercapnia.

About half of the neurons in the parabrachial nucleus (PB) that are activated by CO are located in the external lateral (el) subnucleus, express calcitonin gene-related peptide (CGRP), and cause forebrain arousal. We report here, in male mice, that most of the remaining CO-responsive neurons in the adjacent central lateral (PBcl) and Kölliker-Fuse (KF) PB subnuclei express the transcription factor FoxP2 and many of these neurons project to respiratory sites in the medulla. PBcl neurons show increased intracellular calcium during wakefulness and REM sleep and in response to elevated CO during NREM sleep.

Prolonged activation of EP3 receptor-expressing preoptic neurons underlies torpor responses.

Many species use a temporary drop in body temperature and metabolic rate (torpor) as a strategy to survive food scarcity. A similar profound hypothermia is observed with activation of preoptic neurons that express the neuropeptides Pituitary Adenylate-Cyclase-Activating Polypeptide (PACAP), Brain Derived Neurotrophic Factor (BDNF), or Pyroglutamylated RFamide Peptide (QRFP), the vesicular glutamate transporter, Vglut2 or the leptin receptor (LepR), estrogen 1 receptor (Esr1) or prostaglandin E receptor 3 (EP3R) in mice. However, most of these genetic markers are found on multiple populations of preoptic neurons and only partially overlap with one another.

Lateral parabrachial FoxP2 neurons regulate respiratory responses to hypercapnia.

Although CGRP neurons in the external lateral parabrachial nucleus (PBel neurons) are critical for cortical arousal in response to hypercapnia, activating them has little effect on respiration. However, deletion of all Vglut2 expressing neurons in the PBel region suppresses both the respiratory and arousal response to high CO2. We identified a second population of non-CGRP neurons adjacent to the PBel group in the central lateral, lateral crescent and Kölliker-Fuse parabrachial subnuclei that are also activated by CO2 and project to the motor and premotor neurons that innvervate respiratory sites in the medulla and spinal cord.

Opioids, sleep, analgesia and respiratory depression: Their convergence on Mu (μ)-opioid receptors in the parabrachial area.

Opioids provide analgesia, as well as modulate sleep and respiration, all by possibly acting on the μ-opioid receptors (MOR). MOR's are ubiquitously present throughout the brain, posing a challenge for understanding the precise anatomical substrates that mediate opioid induced respiratory depression (OIRD) that ultimately kills most users. Sleep is a major modulator not only of pain perception, but also for changing the efficacy of opioids as analgesics.

Entyvio lengthen dose-interval study: lengthening vedolizumab dose interval and the risk of clinical relapse in inflammatory bowel disease.

Background: Vedolizumab (VDZ), an α4β7 anti-integrin antibody, is efficacious in the induction and maintenance of remission in ulcerative colitis (UC) and Crohn's disease (CD). In the GEMINI long-term safety study, enrolled patients received 4-weekly VDZ. Upon completion, patients were switched to 8-weekly VDZ in Australia.

Older elite football players have reduced cardiac and osteoporosis risk factors.

Introduction/purpose: Aging with a sedentary lifestyle is associated with increased risk for developing cardiovascular disease (CVD), osteoporosis, and sarcopenia. The purpose of this study was to determine whether former professional football athleticism would be associated with reduced risk factors for CVD and osteoporosis, and higher muscle mass in later life.

Methods: Maximal aerobic capacity (VO2max), body composition, and lipid and glucose risk factors for CVD were compared between 16 older former professional football players and never-athletic men matched for age, body mass index, current physical activity, and race.

Insulin-like growth factor-2 genotype, fat-free mass, and muscle performance across the adult life span.

The influence of insulin-like growth factor-2 (IGF2) genotype on total body fat-free mass (FFM), muscle strength, and sustained power (SP) was evaluated repeatedly at approximately 2-yr intervals in two cohorts from the Baltimore Longitudinal Study of Aging. Cohort 1 was comprised of 94 men tested for isometric grip strength and SP. Cohort 2 was comprised of 246 men and 239 women tested for total body FFM and isokinetic peak torque.

Visceral adipose tissue cutoffs associated with metabolic risk factors for coronary heart disease in women.

Objective: This study determined whether there is a critical level of visceral adipose tissue (VAT) associated with elevated coronary heart disease (CHD) risk factors in a cohort of women >45 years of age.

Research Design And Methods: Measurements of body composition (dual-energy X-ray absorptiometry), body fat distribution (computed tomography), fasting and 2-h postprandial (75-g) glucose concentrations, and fasting lipoprotein lipid and insulin concentrations were performed in 233 perimenopausal (9%) and postmenopausal women (age 59 +/- 6 years, 79% Caucasian, 16% on hormone replacement therapy).

Results: Women in the lowest VAT quintile (< or =105 cm(2)) had higher concentrations of HDL and HDL(2) cholesterol, lower LDL/HDL cholesterol ratios and triglyceride concentrations, and lower fasting glucose and insulin concentrations than women in the remaining four quintiles (P values <0.

Comparison of VO2max and disease risk factors between perimenopausal and postmenopausal women.

Objective: This study determines whether maximal oxygen consumption (VO2 max) is higher in perimenopausal women compared with similarly aged postmenopausal women and whether the lower VO2 max in postmenopausal women is associated with a higher total and visceral fat mass, less favorable lipid and glucose metabolism, and lower bone mineral density (BMD).

Design: Participants were 18 perimenopausal women (mean +/- SD; irregular menstrual cycle in the past 6 months) aged 49 +/- 4 years and 18 postmenopausal women (no menstrual cycle in the past year) aged 52 +/- 2 years who were matched for body mass index and race. Women were sedentary, and none were on hormone replacement therapy.

Differences in adipose tissue metabolism between postmenopausal and perimenopausal women.

Changes in adipose tissue metabolism may contribute to the changes in body fat distribution seen during the menopause transition. We compared in vitro abdominal and gluteal sc adipose tissue metabolism [basal and stimulated lipolysis and activity of adipose tissue lipoprotein lipase (AT-LPL)] in postmenopausal and perimenopausal women (n = 12/group), matched for race, body mass index (29.5 +/- 3.
