Causes, outcomes and diagnosis of acute breathlessness hospital admissions in Malawi: protocol for a multicentre prospective cohort study.

Background: Hospital admission due to breathlessness carries a significant burden to patients and healthcare systems, particularly impacting people in low-income countries. Prompt appropriate treatment is vital to improve outcomes, but this relies on accurate diagnostic tests which are of limited availability in resource-constrained settings. We will provide an accurate description of acute breathlessness presentations in a multicentre prospective cohort study in Malawi, a low resource setting in Southern Africa, and explore approaches to strengthen diagnostic capacity.

Multimorbidity-associated emergency hospital admissions: a "screen and link" strategy to improve outcomes for high-risk patients in sub-Saharan Africa: a prospective multicentre cohort study protocol.

Background: The prevalence of multimorbidity (the presence of two or more chronic health conditions) is rapidly increasing in sub-Saharan Africa. Hospital care pathways that focus on single presenting complaints do not address this pressing problem. This has the potential to precipitate frequent hospital readmissions, increase health system and out-of-pocket expenses, and may lead to premature disability and death.

Concentration Dependence of Elastic and Viscoelastic Properties of Aqueous Solutions of Ficoll and Bovine Serum Albumin by Brillouin Light Scattering Spectroscopy.

The cellular environment is crowded with macromolecules of different shapes and sizes. The effect of this macromolecular crowding has been studied in a variety of synthetic crowding environments: two popular examples are the compact colloid-like Ficoll macromolecule and the globular protein bovine serum albumin (BSA). Recent studies have indicated that a significant component of bound or surface-associated water in these crowders reduces the available free volume.

Use of hospital services by patients with chronic conditions in sub-Saharan Africa: a systematic review and meta-analysis.

Objective: To estimate the prevalence of individual chronic conditions and multimorbidity among adults admitted to hospital in countries in sub-Saharan Africa.

Methods: We systematically searched MEDLINE®, Embase®, Global Index Medicus, Global Health and SciELO for publications reporting on patient cohorts recruited between 1 January 2010 and 12 May 2023. We included articles reporting prevalence of pre-specified chronic diseases within unselected acute care services (emergency departments or medical inpatient settings).

A health systems approach to critical care delivery in low-resource settings: a narrative review.

There is a high burden of critical illness in low-income countries (LICs), adding pressure to already strained health systems. Over the next decade, the need for critical care is expected to grow due to ageing populations with increasing medical complexity; limited access to primary care; climate change; natural disasters; and conflict. In 2019, the 72nd World Health Assembly emphasised that an essential part of universal health coverage is improved access to effective emergency and critical care and to "ensure the timely and effective delivery of life-saving health care services to those in need".

Paediatric admissions to a district general hospital adult intensive care unit over a six year period: A single centre retrospective case series, with review of practitioner confidence and competence in paediatric critical care.

Background: Critically ill children presenting to district general hospitals (DGH) are admitted to adult intensive care units (AICUs) for stabilisation prior to transfer to paediatric intensive care units (PICUs). Current training in PICU for adult intensive care physicians is only three months. This single centre retrospective case series examines the case mix of children presenting to a DGH AICU and a multidisciplinary survey assesses confidence and previous experience, highlighting continued training needs for DGH AICU staff.

Impact of a Novel, Low-Cost and Sustainable Health Education Program on the Knowledge, Attitudes, and Practices Related to Intestinal Schistosomiasis in School Children in a Hard-to-Reach District of Madagascar.

Schistosomiasis control requires multisectoral approaches including praziquantel treatment, access to safe water, sanitation and hygiene, and health education. Community input can help ensure health education programs are culturally appropriate to effectively direct protective behavior change. This study reports on the three-stage development of an education program for Malagasy children, with an impact evaluation on their knowledge, attitudes, and practices (KAP) related to intestinal schistosomiasis.

Nurses' responses to adolescent distress in an acute child and adolescent mental health inpatient unit: A qualitative interpretive descriptive study.

Purpose: To describe observed nursing responses and interventions to adolescent inpatients experiencing distress.

Methods: Thorne's interpretive descriptive approach guided data collection and analysis of nonparticipant observations of a purposive sample of adolescents, and nurses.

Findings: Three major themes are presented: engagement: responses and interventions for working with distress; adolescent reactions and nurses' clinical decision making to manage distress; and outcomes: escalation or resolution of distress.

Prevalence of intestinal schistosomiasis in pre-school aged children: a pilot survey in Marolambo District, Madagascar.

School-aged children (SAC) have a considerable burden of intestinal schistosomiasis in Madagascar yet its burden in pre-school aged children (PSAC) is currently overlooked. To assess the at-risk status of PSAC, we undertook a pilot epidemiological survey in June 2019 examining children (n = 89), aged 2-4-years of balanced gender, in six remote villages in Marolambo District, Madagascar. Diagnosis included use of urine-circulating cathodic antigen (CCA) dipsticks and coproscopy of stool with duplicate Kato-Katz (K-K) thick smears.

Five-Year Follow-Up on the Prevalence and Intensity of Infections of Schistosoma mansoni in a Hard-to-Reach District of Madagascar.

Schistosomiasis is a major public health problem in Madagascar. The WHO recommends preventive chemotherapy by mass drug administration (MDA) with praziquantel as the primary approach to control Schistosoma mansoni-related morbidity in endemic populations, alongside complementary interventions such as health education. The impact of annual MDA and health education programs was assessed in the hard-to-reach Marolambo district of eastern Madagascar, an area endemic for S.

A cross-sectional study of periportal fibrosis and Schistosoma mansoni infection among school-aged children in a hard-to-reach area of Madagascar.

Background: A cross-sectional survey was performed to estimate the prevalence of periportal fibrosis in children based on ultrasound examination in the Marolambo district of the Atsinanana region of Madagascar. This is a remote area known to have a high prevalence of intestinal schistosomiasis.

Methods: School-aged children (5-14 y) were selected from six villages for parasitological and sonographic examination.

The presence of psychological trauma symptoms in resuscitation providers and an exploration of debriefing practices.

Introduction: Witnessing traumatic experiences can cause post-traumatic stress disorder (PTSD). The true impact on healthcare staff of attending in-hospital cardiac arrests (IHCAs) has not been studied. This cross-sectional study examined cardiac arrest debriefing practices and the burden of attending IHCAs on nursing and medical staff.

Adolescents' experiences of distress on an acute mental health inpatient unit: A qualitative study.

Adolescents admitted to acute mental health inpatient units can experience episodes of distress for numerous reasons. Little is known about how they attempt to cope with this distress. This paper explores adolescent experiences of distress in an acute mental health inpatient unit.

High burden of Schistosoma mansoni infection in school-aged children in Marolambo District, Madagascar.

Background: A school-based survey was undertaken to assess prevalence and infection intensity of schistosomiasis in school-aged children in the Marolambo District of Madagascar.

Methods: School-aged children from six purposively selected schools were tested for Schistosoma haematobium by urine filtration and Schistosoma mansoni using circulating cathodic antigen (CCA) and Kato-Katz stool analysis. The investigators did not address soil-transmitted helminths (STH) in this study.

Nonoperative management rather than endovascular repair may be safe for grade II blunt traumatic aortic injuries: An 11-year retrospective analysis.

Background: The Society of Vascular Surgery (SVS) guidelines currently suggest thoracic endovascular aortic repair (TEVAR) for grade II-IV and nonoperative management (NOM) for grade I blunt traumatic aortic injury (BTAI). However, there is increasing evidence that grade II may also be observed safely. The purpose of this study was to compare the outcome of TEVAR and NOM for grade I-IV BTAI and determine if grade II can be safely observed with NOM.

Hospital episode statistics: improving the quality and value of hospital data: a national internet e-survey of hospital consultants.

Hypothesis: Senior hospital clinicians are poorly engaged with clinical coding and hospital episode statistics (HES).

Aims:  ▸ To understand the current level of clinical engagement with collection of national data and clinical coding. ▸ To gain the views of frontline staff on proposed improvements to hospital statistics.

Peripapillary choroidal neovascularisation in the context of ocular syphilis is sensitive to combination antibiotic and corticosteroid treatment.

Peripapillary choroidal neovascularisation (CNV) in the context of ocular syphilis is exceptional and little is known about its natural history and optimal therapeutic management. We report here a case of right eye peripapillary CNV with subretinal fluid encroaching on the fovea in a patient with mild bilateral ocular inflammation and cystoid macular oedema (CMO) in his contralateral eye. Extensive investigations revealed positive serology for active syphilitic infection.

Application of the Three Rs to challenge assays used in vaccine testing: tenth report of the BVAAWF/FRAME/RSPCA/UFAW Joint Working Group on Refinement.

This report aims to facilitate the implementation of the Three Rs (reduction, refinement and replacement) in the testing of vaccines for regulatory and other purposes. The focus is predominantly on identification of reduction and refinement opportunities in batch potency testing but the principles described are widely applicable to other situations that involve experimental infections of animals. The report should also help to interpret the requirements of the European Pharmacopoeia with regard to the use of alternative tests, humane endpoints and other refinements.

Liposomal delivery of p-ialB and p-omp25 DNA vaccines improves immunogenicity but fails to provide full protection against B. melitensis challenge.

Background: We have previously demonstrated protective efficacy against B. melitensis using formulations of naked DNA vaccines encoding genes ialB and omp25. The present study was undertaken to further understand the immune response generated by the protective vaccination regimens and to evaluate cationic liposome adsorption as a delivery method to improve vaccine utility.

Evaluation of the efficacy of a canine influenza virus (H3N8) vaccine in dogs following experimental challenge.

Canine influenza virus (CIV) subtype H3N8 is an emerging pathogen with sustained horizontal transmission in the dog population in the United States. This study evaluated the efficacy of an inactivated CIV vaccine in 6- to 8-week-old beagle pups challenged with virulent CIV. One group of CIV-seronegative pups was vaccinated with two doses of a CIV vaccine 3 weeks apart; a second group of pups received adjuvanted placebo as a control.

Evaluation of azithromycin, trovafloxacin and grepafloxacin as prophylaxis against experimental murine Brucella melitensis infection.

The prophylactic potential of the azalide azithromycin as well as the fluoroquinolones trovafloxacin and grepafloxacin was assessed for the control of infection with Brucella melitensis in an experimental mouse model, determined by reduction in splenic bacterial burden. Trovafloxacin showed limited protective efficacy when administered 2h following a low-dose B. melitensis challenge, whereas grepafloxacin was ineffective.
