Gas transport mechanisms during high-frequency ventilation.

By virtue of applying small tidal volumes, high-frequency ventilation is advocated as a method of minimizing ventilator-induced lung injury. Lung protective benefits are established in infants, but not in other patient cohorts. Efforts to improve and extend the lung protection potential should consider how fundamental modes of gas transport can be exploited to minimize harmful tidal volumes while maintaining or improving ventilation.

Non-adherence to antenatal iron supplementation and its determinants among pregnant women in 35 sub-saharan African countries: a generalized linear mixed-effects modeling with robust Poisson regression analysis.

Background: Despite the integration of iron supplementation into routine antenatal care programs as a nutritional intervention to prevent anemia in pregnant women, the use of this supplement for the recommended duration remains low in sub-Saharan Africa (SSA). Evidence on maternal compliance with iron supplementation at the SSA level is lacking and most of the previous studies have been limited to specific geographic areas. Therefore, the current study used large population survey data from 35 SSA countries to estimate the pooled prevalence of non-adherence and its determinants.

RESCUE - Rapid, Effective, Safe Communication in Emergency Departments: A cross-sectional e-survey.

Background: Effective staff-to-staff and patient-provider communication in the Emergency Department (ED) is essential for safe, quality care. Routine wearing of Personal-Protective-Equipment (PPE) has introduced new challenges to communication. We aimed to understand the perspectives of ED staff about communicating while wearing PPE, and to identify factors contributing to communication success, breakdown, and repair.

Pharmacists as independent prescribers in community pharmacy: A scoping review.

Background: There has been a growing interest in granting prescribing rights to pharmacists as a strategy to improve healthcare access. Researchers continue to explore the impact and implementation of pharmacist prescribing. Given the recent international changes in this field, an overview of current territories allowing pharmacist independent prescribing would provide a comprehensive understanding for researchers and policymakers.

Eradication of commercial tobacco related disease and death.

The eradication of the commercial tobacco industry is a crucial goal for health and well-being, particularly from a public health and health justice perspective. The term 'eradication' is applied in epidemiology to mean the process and outcome of elimination of the-commercial tobacco industry as a human-made-agent of disease and death. In this commentary, we outline why the eradication of the tobacco industry is necessary, urgent and realistic.

Strategic interventions and a novel model for the integration of community pharmacy and primary care in Spain: qualitative insights.

Objectives: To explore the opinions and perceptions of key stakeholders on the integration between community pharmacy and primary care, within the Valencian Autonomous Community. Specific objectives include identifying strategic interventions to facilitate this integration. Additionally, the manuscript discusses the formulation of a novel model for the integration of community pharmacy and primary care.

Conscientious objection: a global health perspective.

Conscientious objection is a critical topic that has been sparsely discussed from a global health perspective, despite its special relevance to our inherently diverse field. In this Analysis paper, we argue that blanket prohibitions of a specific type of non-discriminatory conscientious objection are unjustified in the global health context. We begin both by introducing a nuanced account of conscience that is grounded in moral psychology and by providing an overview of discriminatory and non-discriminatory forms of objection.

Inequalities in ownership and availability of home-based vaccination records in 82 low- and middle-income countries.

Introduction: Home-based records (HBRs) are widely used for recording health information including child immunisations. We studied levels and inequalities in HBR ownership in low-income and middle-income countries (LMICs) using data from national surveys conducted since 2010.

Methods: We used data from national household surveys (Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS)) from 82 LMICs.

Cost-effectiveness analysis of proactive home visits compared with site-based community health worker care on antenatal care outcomes in Mali: a cluster-randomised trial.

Introduction: Despite recommendations from the WHO, antenatal care (ANC) coverage remains low in many low-income and middle-income countries (LMICs). Community health workers (CHWs) can play an important role in expanding ANC coverage through pregnancy identification, provision of health education, screening for complications, delivery of therapeutic care and referral to higher levels of care. However, despite the success of CHW programmes in various countries, WHO has called for additional research to develop evidence-based models that optimise CHW service delivery and that can be replicated across geographies.

Falls prevention in an older adult mental health ward through a quality improvement initiative.

Falls in the inpatient units are the most frequently reported patient safety incidents and their consequences can be devastating. Risk factors for falls are broadly categorised into two factors-'extrinsic and intrinsic' and while the effect of functional mental health conditions on falls has not been extensively studied, older adults with dementia are at a higher risk of falling. Their impact could lead to delayed functional recovery, distress, increased length of hospital stays and an increased fear of falling.

Ozone Concentration, Physical Activity, and Emotional and Behavioral Problems in Children and Adolescents.

Background: No prior study has examined the mutual association of long-term outdoor ozone (O) concentration and physical activity (PA) with emotional and behavioral problems (EBPs) in children and adolescents. This study aims to investigate the association between long-term outdoor O concentration and the risk of EBPs in children and adolescents and further explore whether increased PA levels modify this association.

Methods: Data were obtained from the 2020 wave follow-up examination of an ongoing prospective cohort study (COHERENCE project) in Guangzhou, China.

Effect of Medium Chain Triglycerides and Whey Protein Isolate Preloads on Glycaemia in Type 2 Diabetes: A randomised crossover study.

Background: Small nutritional preloads can reduce postprandial glucose excursions in individuals with and without metabolic syndrome or T2D. However, most studies have focused on preloads administered before single meals and have predominantly used protein-based preloads.

Objective: To investigate the effects of sequential consumption of medium chain triglycerides (MCT) and whey protein isolate (WPI) preloads before breakfast lunch and dinner on postprandial, diurnal and 24h glycaemia in individuals with T2D.

Proteomic analysis of natural photoheterotrophic mixed consortium for biohydrogen production under nongrowing conditions.

A biohydrogen and polyhydroxyalkanoates(PHA)-producing natural photoheterotrophic mixed culture composed mainly by Rhodopseudomonas palustris and Clostridium sp was studied by a proteomic analysis under non-growth conditions (nitrogen-absence and organic acids). Proteins in C. pasteurianum were upregulated, particularly those related to stress response.

Seroprevalence of canine distemper virus antibodies in free-roaming dogs in Cambodia.

Canine distemper virus (CDV) can infect a wide range of mammalian carnivores and can cause severe illness and death. Domestic dogs may be an important source of this virus for endangered wild carnivores. The objective of this study was to establish the presence of CDV in rural areas of Cambodia bordering three established protected habitats, and to determine the seroprevalence of CDV in free-roaming dogs inhabiting these areas.

IUPHAR Themed Review: The Gut Microbiome in Schizophrenia.

Gut microbial dysbiosis or altered gut microbial consortium, in schizophrenia suggests a pathogenic role through the gut-brain axis, influencing neuroinflammatory and neurotransmitter pathways critical to psychotic, affective, and cognitive symptoms. Paradoxically, conventional psychotropic interventions may exacerbate this dysbiosis, with antipsychotics, particularly olanzapine, demonstrating profound effects on microbial architecture through disruption of bacterial phyla ratios, diminished taxonomic diversity, and attenuated short-chain fatty acid synthesis. To address these challenges, novel therapeutic strategies targeting the gut microbiome, encompassing probiotic supplementation, prebiotic compounds, faecal microbiota transplantation, and rationalised co-pharmacotherapy, show promise in attenuating antipsychotic-induced metabolic disruptions while enhancing therapeutic efficacy.

Conceptualizing patient-level adverse effects in implementation trials.

Identifying and monitoring adverse effects (AEs) are integral to ensuring patient safety in clinical trials. Research sponsors and regulatory bodies have put into place a variety of policies and procedures to guide researchers in protecting patient safety during clinical trials. However, it remains unclear how these policies and procedures should be adapted for trials in implementation science.

The gut-brain axis: Unveiling the impact of xenobiotics on neurological health and disorders.

The Gut-Brain Axis (GBA) is a crucial link between the gut microbiota and the central nervous system. Xenobiotics, originating from diverse sources, play a significant role in shaping this interaction. This review examines how these compounds influence neurotransmitter dynamics within the GBA.

Rapid confirmation of autochthonous origin in suspected cases of melioidosis from French overseas departments in the Caribbean and the Indian Ocean by PCR-high resolution melting (HRM) analysis.

Burkholderia pseudomallei, a soil-borne bacterium that causes melioidosis, endemic in South and Southeast Asia and northern Australia, is now emerging in new regions. Since the 1990s, cases have been reported in French overseas departments, including Martinique and Guadeloupe in the Caribbean, and Reunion Island and Mayotte in the Indian Ocean, suggesting a local presence of the bacterium. Our phylogenetic analysis of 111 B.

Effects of molecular weight of chitosan on its binding ability with OSA starch and oil-water interface behavior of complex-stabilized emulsion.

This work examined the effects of molecular weight (2-15 kDa) and concentration (10-30 mg/mL) of chitosan (CTS) on the binding capacity and interface behavior between octenyl succinic acid sodium starch (OSS) and CTS, as well as their effects on the storage stability of emulsions. The results of the isothermal calorimetry titration demonstrated that OSS and CTS were complexed by electrostatic interaction and spontaneous hydrogen bonding driven by enthalpy (ΔH from -3931 to -7983 cal/mol, ΔS from -38.5 to -49.

Antisense oligonucleotides-based approaches for the treatment of multiple myeloma.

Multiple myeloma (MM), a hematological malignancy which affects the monoclonal plasma cells in the bone marrow, is in rising incidence around the world, accounting for approximately 2 % of newly diagnosed cancer cases in the US, Australia, and Western Europe. Despite the progress made in the last few years in the available therapeutic options (e.g.

Cardio-metabolic and cytoskeletal proteomic signatures differentiate stress hypersensitivity in dystrophin-deficient mdx mice.

Extreme heterogeneity exists in the hypersensitive stress response exhibited by the dystrophin-deficient mdx mouse model of Duchenne muscular dystrophy. Because stress hypersensitivity can impact dystrophic phenotypes, this research aimed to understand the peripheral pathways driving this inter-individual variability. Male and female mdx mice were phenotypically stratified into "stress-resistant" or "stress-sensitive" groups based on their response to two laboratory stressors.

Competing mechanisms for the buckling of an epithelial monolayer identified using multicellular simulation.

A model using the rigid body multi-cellular framework (RBMCF) is implemented to investigate the mechanisms of buckling of an epithelial monolayer. Specifically, the deformation of a monolayer of epithelial cells which are attached to a basement membrane and the surrounding stromal tissue. The epithelial monolayer , supporting basement membrane and stromal tissue are modelled using two separate vertex dynamics models (one for the epithelial monolayer layer and one for the basement membrane and stromal tissue combined) and interactions between the two are considered using the RBMCF to ensure biologically realistic interactions.

Mouth Rinsing and Ingesting Unpleasant Salty or Bitter Solutions After Heavy-Intensity Cycling Does Not Influence Sprint Performance or Knee-Extensor Force in Trained Cyclists.

Purpose: The present study investigated the effect of unpleasant salty or bitter tastes on cycling sprint performance and knee-extensor force characteristics in different fatigue states.

Methods: Following a familiarization session, 11 trained male cyclists completed 3 experimental trials (salty, bitter, and water) in a randomized crossover order. In each trial, participants cycled at 85% of the respiratory compensation point for 45 minutes and then, after a 5-minute rest, completed a 1-minute sprint.
