Leptospirosis is a significant public health concern worldwide, as it imposes a substantial economic burden on the global economy. Despite a comprehensive search of the relevant literature, few studies evaluating the economic burden experienced by leptospirosis patients were identified. In particular, very few studies thoroughly examined the cost components, including direct, indirect and intangible costs. This paucity of evidence further motivates the need to conduct a more focused search using a systematic review approach. Thus, this study aims to systematically review the global literature on the magnitude and aspects of the direct, indirect and intangible costs incurred by leptospirosis patients and the methods available for assessing these costs.

This review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols 2015 guidelines. The Population, Intervention, Comparison, Outcomes, Study Design framework was used to develop the review questions. The search strategy will comprise two key term blocks: ‘Leptospirosis’ and ‘Economic cost’. A comprehensive literature search will be conducted in PubMed, Web of Science, Scopus, MEDLINE, CINAHL, the Cochrane Library, EconStor and IDEAS to collect publications from inception to July 2025. The search will be limited only to English-language and peer-reviewed publications. The Mixed Methods Appraisal Tool will be used to assess the quality of eligible studies. Extracted cost data will be categorised into direct, indirect and intangible costs. A meta-analysis will be conducted to quantify the magnitude of these costs if sufficient methodological and contextual homogeneity exists. Moreover, a narrative synthesis will be performed to analyse the qualitative data related to intangible costs.

As this study will use secondary data, ethical approval is not required. The systematic review’s findings will be published in a scientific journal and presented at relevant conferences to address the knowledge gap regarding the economic burden (including direct, indirect and intangible costs) faced by leptospirosis patients. The results of this systematic review will guide policies for prioritising prevention, improving surveillance and efficiently allocating resources to control leptospirosis.

Heart failure (HF) remains a major global health challenge, particularly in low-resource settings where access to comprehensive cardiac rehabilitation (CR) is limited. Yoga, a culturally contextualised mind-body intervention, holds promise as an adjunctive therapy in CR. The Yoga-EndOmics study aims to evaluate the effects of Yoga-based cardiac rehabilitation (Yoga-CaRe) on gene expression, endothelial function, vascular biomarkers and clinical outcomes in systolic HF, providing mechanistic insights into its potential integration into conventional cardiac rehabilitation.

This is a prospective, randomised, open-label, blinded-endpoint (PROBE) mechanistic trial enrolling 78 patients with HF with reduced ejection fraction (HFrEF). Participants will be randomised in a 1:1 ratio to receive either a structured Yoga-CaRe intervention or enhanced standard care for 3 months. The Yoga-CaRe group will attend 20 supervised sessions with guided home practice involving tailored asanas, pranayama and meditation. Primary outcomes are changes in endothelial-dependent flow-mediated dilation (FMD) and functional exercise capacity at 3 months. Secondary outcomes include changes in arterial compliance and stiffness, circulating biomarkers of endothelial dysfunction, oxidative stress and inflammation, and immediate changes in global gene expression profiles in peripheral blood mononuclear cells following the Yoga-CaRe intervention. Data will be analysed using analysis of covariance (ANCOVA) for between-group comparisons and significant analysis of microarray (SAM) for global gene expression profiles.

The study has received ethical clearance from the Institutional Ethics Committee of the SDM College of Medical Sciences and Hospital, India (SDMIEC/2025/1072) and is registered with the Clinical Trials Registry of India. Findings will be disseminated through peer-reviewed journals, scientific conferences and stakeholder engagement platforms to inform future integrative strategies in HF management.

Our aim is to develop a Framework of Measurement for people living with Long COVID and their caregivers for use in Long COVID research and clinical practice. Specifically, we will characterise evidence pertaining to outcome measurement and identify implementation considerations for use of outcome measures among adults and children living with Long COVID and their caregivers.

We will conduct a scoping study involving: (1) an evidence review and (2) a two-phased consultation, using methodological steps outlined by the Arksey and O’Malley Framework and Joanna Briggs Institute. We will answer the following question: What is known about outcome measures used to describe, evaluate or predict health outcomes among adults and children living with Long COVID and their caregivers? Evidence review: we will review peer review published and grey literature to identify existing outcome measures and their reported measurement properties with people living with Long COVID and their caregivers. We will search databases including MEDLINE, Embase, CINAHL, PsycINFO and Scopus for articles published since 2020. Two authors will independently review titles and abstracts, followed by full text to select articles that discuss or use outcome measures for Long COVID health outcomes, pertain to adults or children living with Long COVID and/or their caregivers and are based in research or clinical settings. We will extract data including article characteristics, terminology and definition of Long COVID, health outcomes assessed, characteristics of outcome measures, measurement properties and implementation considerations. We will collate and summarise data to establish a preliminary Framework of Measurement. Consultation phase 1: we will conduct an environmental scan involving a cross-sectional web-based questionnaire among individuals with experience using or completing outcome measures for Long COVID, to identify outcome measures not found in the evidence review and explore implementation considerations for outcome measurement in the context of Long COVID. Consultation phase 2: we will conduct focus groups to review the preliminary Framework of Measurement and to highlight implementation considerations for outcome measurement in Long COVID. We will analyse questionnaire and focus group data using descriptive and content analytical approaches. We will refine the Framework of Measurement based on the focus group consultation using community-engaged approaches with the research team.

Protocol approved by the University of Toronto Health Sciences Research Ethics Board (protocol #46503) for the consultation phases of the study. Outcomes will include a Framework of Measurement, to enhance measurement of health outcomes in Long COVID research and clinical practice. Knowledge translation will also occur in the form of publications and presentations.

Recent studies have demonstrated a beneficial role of steroids in severe community-acquired pneumonia, severe COVID-19 infection and acute respiratory distress syndrome (ARDS) of diverse aetiology. This multicentre randomised controlled trial in severe scrub typhus pneumonitis and ARDS will compare the effects of 6 mg of dexamethasone once per day with placebo, in addition to standard treatment, on ventilator-free days (VFD), mortality and ventilatory requirement.

The study, involving six sites, will recruit 440 patients with severe scrub typhus pneumonitis or ARDS to concealed, block-randomised, site-specific assignment of dexamethasone or placebo for 4–7 days. The primary outcome will be VFD, defined as days alive and free of ventilation at 28 days. Secondary outcomes will include 28-day mortality, need and duration of ventilation, and treatment failure, defined as death, or escalation of respiratory support from simple devices (nasal cannula, mask) to non-invasive or invasive ventilation, or the use of open-labelled steroids for worsening shock. The study will also ascertain if antinuclear antibody (ANA) expression during the acute phase of illness will predict steroid responsiveness. Subgroup analyses will be conducted a priori on ANA expression and the need for ventilation. All analyses will be conducted on an intention-to-treat basis. The trial, which commenced in April 2025, would clarify the role of corticosteroids in scrub typhus pneumonitis.

The Institutional Review Board and Ethics Committee of the lead site, Christian Medical College, Vellore, India, has approved the study (IRB Min No 15920 (INTERVE) dated 22 November 2023). The remaining five sites have obtained approval from their respective ethics committees. Study results will be published in an international peer-reviewed journal.

This study explored the barriers to and facilitators of weight reduction among urban, young adults with obesity in Sri Lanka.

A qualitative descriptive study, using the framework method in thematic analysis to identify key themes for barriers and facilitators.

An urban community setting in Sri Lanka in January–March 2022.

62 young adults (18–35 years) with obesity (body mass index ≥25 kgm^-2) representing different socio-demographic characteristics were recruited into the focus group discussions (n=10).

The majority of participants were women (n=40; 64.5%). More than 70% (n=45) of the participants were classified as having class I obesity. Inconsistent knowledge, emotions and mood, poor self-control, inadequate support from others, lack of time, lack of resources and facilities and unsafe environment for physical activities were the identified barriers. The desire to improve appearance and body image, health-related concerns, limitations to day-to-day activities, previous positive experiences, support from others and weight-related victimisation were identified as facilitators.

A multitude of factors were found to interfere with weight-reduction attempts. Due consideration of these barriers and facilitators is important when planning weight management programmes targeting young adults with obesity.
