Stem cell-derived extracellular vesicles: a potential intervention for Bronchopulmonary Dysplasia.

Despite advances in neonatal care, the incidence of Bronchopulmonary Dysplasia (BPD) remains high among extreme preterm infants. The pathogenesis of BPD is multifactorial, with inflammation playing a central role. There is strong evidence that stem cell therapy reduces inflammatory changes and restores normal lung morphology in animal models of hyperoxia-induced lung injury.

The physical, technical and tactical demands of on-field training drills in professional Rugby league: a systematic scoping review.

Objectives: The main objectives of this scoping review were to conduct a systematic search on the physical, technical and tactical demands of rugby league training, consolidate and summarise key findings and identify any existing gaps in knowledge.

Methods: A systematic online search of Scopus, PubMed, MEDLINE and SPORTDiscus was conducted from earliest record to 6 August 2023 and supplemented by manually searching reference lists. The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist was followed.

Effectiveness of extracellular vesicles derived from hiPSCs in repairing hyperoxia-induced injury in a fetal murine lung explant model.

Background: Despite advances in neonatal care, the incidence of Bronchopulmonary Dysplasia (BPD) remains high among preterm infants. Human induced pluripotent stem cells (hiPSCs) have shown promise in repairing injury in animal BPD models. Evidence suggests they exert their effects via paracrine mechanisms.

Obesity and Adipose Tissue Dysfunction: From Pediatrics to Adults.

Obesity is a growing health problem that affects both children and adults. The increasing prevalence of childhood obesity is associated with comorbidities such as cardiovascular disease, type 2 diabetes and metabolic syndrome due to chronic low-grade inflammation present at early stages of the disease. In pediatric patients suffering from obesity, the role of epigenetics, the gut microbiome and intrauterine environment have emerged as causative factors Interestingly, pediatric obesity is strongly associated with low birth weight.

Hidden in plain sight? Identifying patient-authored publications.

Background: Patient advocates are increasingly authoring peer-reviewed publications that could enhance patient care and understanding of the lived experience. Although patient authorship may be seen as an innovation in the peer-reviewed publication environment and some may not be aware of or accept patient authorship, we know patient-authored publications exist. However, identifying patient-authored publications is often challenging and time-consuming.

Changes in COVID-19-Associated Deaths During a Year Among Blacks and Hispanics Compared to Whites in the State of Connecticut.

Background: With recent COVID-19 vaccination rates relatively high in the USA, the USA still maintains the most documented cases globally,[1] even though COVID-19 cases, hospitalization, and mortality have been declining. However, the health burden has been largely felt in communities involving racial and ethnic minorities. Thus, in order to provide a clearer picture of what is happening in Black, Indigenous, and people of color communities, we examined the racial/ethnic differences of monthly COVID-19 deaths in Connecticut.

Fentanyl, Heroin, and Cocaine Overdose Fatalities are Shifting to the Black Community: An Analysis of the State of Connecticut.

Background: Historically, Blacks and Hispanics have had lower opioid-involved overdose death rates in Connecticut (CT). We examined if a shift has taken place where rates of Black fatal overdoses have now surpassed Whites in the state.

Methods: Drug overdose fatality rates were calculated by number of deaths per year per 100,000 population from 2012 to 2019 in Connecticut.

Excess Deaths Among Blacks and Latinx Compared to Whites During Covid-19.

Importance: Blacks and Latinx are disproportionately affected by Coronavirus disease 2019 (Covid-19) and experience higher mortality rates than Whites and Asians in the USA. Such racial disparities, in Covid-19 testing, cases, and mortality are visible in Connecticut too. Recently, excess deaths have become an important consideration in news reports and academic research.

An Unanticipated Role for Sphingosine Kinase-2 in Bone and in the Anabolic Effect of Parathyroid Hormone.

Sphingosine-1-phosphate (S1P) is an anabolic clastokine. Sphingosine kinase (SPHK) is the rate-limiting enzyme in S1P production and has 2 isoforms. To evaluate the roles of SPHK1 and SPHK2 in bone, we examined the skeletal phenotype of mice with selective deletion of SPHK1 in osteoclasts (SPHK1-Oc-/-) and mice in which the SPHK2 gene was deleted in all tissues (SPHK2-/-).

A Pandemic on a Pandemic: Racism and COVID-19 in Blacks.

Racism and COVID-19 represent a pandemic on a pandemic for Blacks. The pandemics find themselves synergized to the detriment of Blacks and their health. The complexity of the combination of these pandemics are evident when examining the interplay between racist policing practices and health.

Racial Profiling Is a Public Health and Health Disparities Issue.

Racial profiling is a public health and health disparities issue through its disparate and adverse health impact on those targeted by this practice, as well as members of their communities. We discuss six ways police profiling and racial discrimination adversely impact Black American health. We identify four direct and two indirect ways.

Identification of a 22 bp DNA cis Element that Plays a Critical Role in Colony Stimulating Factor 1-Dependent Transcriptional Activation of the SPHK1 Gene.

Sphingosine-1-phosphate (S1P) is an anabolic clastokine. Colony Stimulating Factor 1 (CSF1) induces expression of the rate limiting enzyme required for S1P synthesis, sphingosine kinase 1 (SPHK1) in bone in vivo, and in osteoclasts in vitro. To study the mechanism of CSF1-induced SPHK1 gene expression, a 2608 bp fragment of the murine SPHK1 gene (- 2497 to + 111 bp relative to the transcription start site) was cloned and transfected into pZen cells (murine fibroblasts engineered to express c-fms).

Evaluation of Incisional Negative Pressure Wound Therapy in the Prevention of Surgical Site Occurrences After Radical Cystectomy: A New Addition to Enhanced Recovery After Surgery Protocol.

Background: Surgical site infection (SSI) remains a significant complication after radical cystectomy (RC). Enhanced recovery after surgery (ERAS) focuses on interventions to decrease length of stay, but few address wound-related complications directly.

Objective: To determine the impact that prophylactic incisional negative pressure wound therapy (iNPWT) will have to reduce the rate of surgical site occurrences (SSOs = SSI + seroma + superficial dehiscence) after RC.

The contribution of cross-talk between the cell-surface proteins CD36 and CD47-TSP-1 in osteoclast formation and function.

Antibody-mediated blockade of cluster of differentiation 47 (CD47)-thrombospondin-1 (TSP-1) interactions blocks osteoclast formation and attenuates parathyroid hormone (PTH)-induced hypercalcemia in mice. Hypercalcemia in this model reflects increased bone resorption. TSP-1 has two cell-associated binding partners, CD47 and CD36.

Public health guide to field developments linking ecosystems, environments and health in the Anthropocene.

The impacts of global environmental change have precipitated numerous approaches that connect the health of ecosystems, non-human organisms and humans. However, the proliferation of approaches can lead to confusion due to overlaps in terminology, ideas and foci. Recognising the need for clarity, this paper provides a guide to seven field developments in environmental public health research and practice: occupational and environmental health; political ecology of health; environmental justice; ecohealth; One Health; ecological public health; and planetary health.
