5-HT agonism as a neurotherapeutic for sarcopenia: preclinical proof of concept.

Sarcopenia, the pathological age-related loss of muscle mass and strength, contributes to physical decline, frailty, and diminished healthspan. The impact of sarcopenia is expected to rise as the aging population grows, and treatments remain limited. Therefore, novel approaches for enhancing physical function and strength in older adults are desperately needed.

Improving the adoption of a school-based nutrition program: findings from a collaborative network of randomised trials.

Background: Public health nutrition interventions, including school-based programs, are a recommended approach to improve child dietary behaviours. However, the adoption of effective school-based nutrition programs face numerous challenges, including the limited evidence on effective strategies to maximise implementation and adoption of such programs. This study aimed to address this evidence gap by employing a novel collaborative network trial design to evaluate a series of implementation strategies employed by three NSW Local Health Districts, to improve school adoption of an effective school-based nutrition program ('SWAP IT').

Cognitive impairment caused by compromised hepatic ketogenesis is prevented by endurance exercise.

Extensive research has demonstrated endurance exercise to be neuroprotective. Whether these neuroprotective benefits are mediated, in part, by hepatic ketone production remains unclear. To investigate the role of hepatic ketone production on brain health during exercise, healthy 6-month-old female rats underwent viral knockdown of the rate-limiting enzyme in the liver that catalyses the first reaction in ketogenesis: 3-hydroxymethylglutaryl-CoA synthase 2 (HMGCS2).

Dialectical Behavior Therapy Skills Training as a Brief Intervention for Cigarette Smoking by Patients With Cancer: A Scoping Review and Narrative Synthesis of Related Literature.

Objective: Novel behavioral interventions are needed for patients with cancer who smoke cigarettes. Standard tobacco treatment may not effectively address the psychological distress and/or emotion dysregulation that makes quitting smoking difficult for many patients. Dialectical Behavior Therapy-Skills Training (DBT-ST) has demonstrated efficacy as a brief intervention for managing emotions and stress across varied populations but has not been adapted for patients with cancer who smoke.

Feasibility of implementing a culturally and linguistically adapted telephone-based cognitive-behavioral therapy (CBT) intervention for depression and anxiety with Hispanic and Latino cancer survivors.

Purpose/objectives: Hispanic and Latino (hereafter 'H/L') cancer survivors report higher rates of anxiety/depression and are less likely to receive psychosocial services than other survivors. We field-tested a culturally and linguistically adapted cognitive-behavioral therapy intervention with H/L post-treatment cancer survivors. Goals were to: (1) assess feasibility; (2) describe future efficacy outcomes; and (3) examine feedback for refinements.

Care of the Transgender Surgical Client: A Video Simulation for Baccalaureate Nursing Students.

Background: Nursing curriculum lacks content addressing care of transgender (trans) individuals. Gender diversity in health care education must be enhanced to prevent discrimination and systemic biases.

Method: A shared session between pediatric and medical-surgical courses using an interactive video simulation facilitated student preparation to provide inclusive care for trans surgical clients.

Catecholamine-Induced Inflammasome Activation in the Heart Following Photothrombotic Stroke.

Cerebrovascular stroke patients exhibit an increased incidence of cardiac arrhythmias. The pathomechanisms underlying post-traumatic cardiac dysfunction include a surge of catecholamines and an increased systemic inflammatory response, but whether inflammasome activation contributes to cardiac dysfunction remains unexplored. Here, we used a mouse model of photothrombotic stroke (PTS) to investigate the role of inflammasome activation in post-stroke cardiac dysfunction by catecholamines and to evaluate the effectiveness of the inflammasome inhibitor IC100 on inflammasome activation.

Longitudinal DNA methylation in parent-infant pairs impacted by intergenerational social adversity: An RCT of the Michigan Model of Infant Mental Health Home Visiting.

Introduction: Early childhood development is a strong predictor of long-term health outcomes, potentially mediated via epigenetics (DNA methylation). The aim of the current study was to examine how childhood experiences, punitive parenting, and an intergenerational psychotherapeutic intervention may impact DNA methylation in young children and their mothers.

Methods: Mothers and their infants/toddlers between 0 and 24 months were recruited at baseline (n = 146, 73 pairs) to participate in a randomized control trial evaluating the effectiveness of The Michigan Model of Infant Mental Health Home Visiting (IMH-HV) parent-infant psychotherapy compared to treatment as usual.

Expert assessment of illegal collecting impacts on Venus flytraps and priorities for research on illegal trade.

Illegal collecting of wild Venus flytraps (Dionaea muscipula) for the horticultural trade represents a persistent threat to populations of the species across their endemic range in the coastal plain of North and South Carolina (United States). Although wild collecting of Venus flytraps is not a novel threat, there has been very little research on the impacts of collecting on the species' conservation to date or why an illegal trade persists alongside a legal one. We drew on qualitative expert stakeholder elicitation to contextualize the threat of illegal collecting to the long-term conservation of Venus flytraps in relation to other anthropogenic threats.

Management of metacarpal shaft fractures.

Aims: The aims of this study were to describe the epidemiology of metacarpal shaft fractures (MSFs), assess variation in treatment and complications following standard care, document hospital resource use, and explore factors associated with treatment modality.

Methods: A multicentre, cross-sectional retrospective study of MSFs at six centres in the UK. We collected and analyzed healthcare records, operative notes, and radiographs of adults presenting within ten days of a MSF affecting the second to fifth metacarpal between 1 August 2016 and 31 July 2017.

Where Are the Sore Losers? Competitive Authoritarianism, Incumbent Defeat, and Electoral Trust in Zambia's 2021 Election.

How do electoral turnovers shape citizen perceptions of election quality in competitive authoritarian regimes? We argue that electoral outcomes are crucial for determining perceptions of electoral quality. While detailed evaluation of electoral trust is complex in competitive autocracies with institutional uncertainty and polarized electoral environments, turnovers send strong and unequivocal signals about election quality. Previous literature has noted a strong partisan divide in electoral trust in competitive authoritarian regimes, but turnovers can boost trust among both incumbent and opposition supporters.

Hindlimb immobilization induces insulin resistance and elevates mitochondrial ROS production in the hippocampus of female rats.

Alzheimer's disease (AD) is the fifth leading cause of death in older adults, and treatment options are severely lacking. Recent findings demonstrate a strong relationship between skeletal muscle and cognitive function, with evidence supporting that muscle quality and cognitive function are positively correlated in older adults. Conversely, decreased muscle function is associated with a threefold increased risk of cognitive decline.

Beneficial Effects of Human Schwann Cell-Derived Exosomes in Mitigating Secondary Damage After Penetrating Ballistic-Like Brain Injury.

There is a growing body of evidence that the delivery of cell-derived exosomes normally involved in intracellular communication can reduce secondary injury mechanisms after brain and spinal cord injury and improve outcomes. Exosomes are nanometer-sized vesicles that are released by Schwann cells and may have neuroprotective effects by reducing post-traumatic inflammatory processes as well as promoting tissue healing and functional recovery. The purpose of this study was to evaluate the beneficial effects of human Schwann-cell exosomes (hSC-Exos) in a severe model of penetrating ballistic-like brain injury (PBBI) in rats and investigate effects on multiple outcomes.

Inclusive Fitness May Explain Some but Not All Benefits Derived from Helping Behavior in a Cooperatively Breeding Bird.

AbstractIn cooperative breeding systems, inclusive fitness theory predicts that nonbreeding helpers more closely related to the breeders should be more willing to provide costly alloparental care and thus have more impact on breeder fitness. In the red-cockaded woodpecker (), most helpers are the breeders' earlier offspring, but helpers do vary within groups in both relatedness to the breeders (some even being unrelated) and sex, and it can be difficult to parse their separate impacts on breeder fitness. Moreover, most support for inclusive fitness theory has been positive associations between relatedness and behavior rather than actual fitness consequences.

Outcomes of Strabismus Surgery Following Teprotumumab Therapy.

Purpose: To investigate the results of patients undergoing surgical treatment for strabismic diplopia in thyroid eye disease (TED) following teprotumumab.

Design: Multicenter, retrospective, case series.

Methods: We report 28 patients who underwent extraocular muscle surgery for strabismic diplopia after treatment with teprotumumab at 7 different academic centers.

Prostaglandin FP receptor agonists in the treatment of glaucoma and ocular hypertension: a literature review.

Introduction: Glaucoma is a leading cause of blindness with intraocular pressure (IOP) as the only known modifiable risk factor. Prostaglandin FP receptor agonists are the first-line medical treatment for glaucoma and ocular hypertension. Despite their efficacy, their IOP lowering effect may be insufficient requiring second agents, and poor patient compliance to medical therapy may preclude their full effect.

Quantitative assessment of spicule length in spp. (Nematoda, Heligmosomidae): distinction between , and .

Nematode spicules play a vital role in the reproductive activity of species that possess them. Our primary objective was to compare the lengths of spicules of the laboratory mouse () – maintained isolate – with those of from naturally infected wood mice (). On a more limited scale, we also included from bank voles (), a species reputed to possess longer spicules than either of the 2 former species.

Outbreak of Locally Acquired Mosquito-Transmitted (Autochthonous) Malaria - Florida and Texas, May-July 2023.

Eight cases of locally acquired, mosquito-transmitted (i.e., autochthonous) Plasmodium vivax malaria, which has not been reported in the United States since 2003, were reported to CDC from state health departments in Florida and Texas during May 18-July 17, 2023.

Evaluating the scaling up of an effective implementation intervention (PACE) to increase the delivery of a mandatory physical activity policy in primary schools.

Background: Physically Active Children in Education (PACE) is an effective implementation intervention for increasing the number of minutes classroom teachers schedule physical activity each week. To date, evaluations of PACE have included a smaller number of schools from only one region in New South Wales Australia. If PACE is to have population-wide benefits we must be able to deliver this support to a larger number of schools across multiple regions.

A Scoping Review of Economic Evaluations to Inform the Reorientation of Preventive Health Services in Australia.

The Australian National Preventive Health Strategy 2021-2030 recommended the establishment of evidence-based frameworks to enable local public health services to identify strategies and interventions that deliver value for money. This study aimed to review the cost-effectiveness of preventive health strategies to inform the reorientation of local public health services towards preventive health interventions that are financially sustainable. Four electronic databases were searched for reviews published between 2005 and February 2022.

Visual Outcomes, Spectacle Independence, and Patient-Reported Satisfaction of the Vivity Extended Range of Vision Intraocular Lens in Patients with Early Glaucoma: An Observational Comparative Study.

Purpose: This study aimed to evaluate and compare visual outcomes, spectacle independence, and patient satisfaction on bilaterally implanted Vivity extended depth-of-focus (EDOF) or monofocal intraocular lenses (IOLs) after cataract surgery in patients with early glaucoma.

Patients And Methods: In this retrospective, non-randomized, interventional cohort study, patients with early glaucoma undergoing cataract surgery received bilateral implantation of either EDOF (AcrySof IQ Vivity; Alcon) or monofocal (Clareon/SN6ATx/SN60WF; Alcon) IOLs. The primary outcome was monocular uncorrected intermediate visual acuity (UIVA).

Strategies for fixation of periprosthetic fragility fractures of the neck of femur below a well-functioning hip resurfacing arthroplasty: A case-series.

Introduction: Metal-on-metal Hip Resurfacing (HR) was performed in many young individuals as it conserved bone stock and had low wear rates, before it became less popular due to the detection of Adverse Reactions to Metal Debris. As such, many patients in the community have well-functioning HRs and as they age, the incidence of fragility fractures of the neck of femur around the existing implant is expected to increase. These fractures are amenable to surgical fixation as adequate bone stock remains in the head of the femur and the implants are well fixed.

Selective breeding for physical inactivity produces cognitive deficits altered hippocampal mitochondrial and synaptic function.

Physical inactivity is the 4th leading cause of death globally and has been shown to significantly increase the risk for developing Alzheimer's Disease (AD). Recent work has demonstrated that exercise prior to breeding produces heritable benefits to the brains of offspring, suggesting that the physical activity status of previous generations could play an important role in one's brain health and their subsequent risk for neurodegenerative diseases. Thus, our study aimed to test the hypothesis that selective breeding for physical inactivity, or for high physical activity, preference produces heritable deficits and enhancements to brain health, respectively.
