Methotrexate (MTX) is used in treating several malignancies. However, MTX neurotoxicity remains a significant clinical side effect, leading to cell division malformation, and neurogenesis impairment. Chrysin, a flavonoid compound found in natural products, demonstrates various biological characteristics, including neuroprotective and antioxidant properties. The purpose of this study was to investigate the ameliorative effect of chrysin on oxidative damage and neurogenesis impairment caused by MTX. Male Sprague-Dawley rats were randomly divided into four groups, including the vehicle, MTX (75 mg/kg), chrysin (10 mg/kg), and chrysin+MTX groups. Chrysin was orally administered for 15 days. MTX was administered intravenously on days 8 and 15. The hippocampal neural stem cells were evaluated using sex determining region Y-box 2 (sox2) and nestin immunofluorescence staining. Antioxidant enzyme expression and the levels of oxidative stress marker were assessed. Additionally, the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), brain-derived neurotrophic factor (BDNF), cAMP-response element binding (CREB), and phosphorylated CREB (pCREB) were evaluated using Western blotting. Results showed that MTX significantly decreased the activity of antioxidant enzymes and produced oxidative stress. MTX also impaired neurogenesis, evidenced by decreased sox2 and nestin-positive cells and decreased expression of Nrf2, BDNF, CREB, and pCREB in the hippocampus and prefrontal cortex. However, chrysin significantly reversed the effects of MTX on these parameters. In conclusion, chrysin exhibits neuroprotective effects against MTX-induced neurogenesis impairment by upregulating antioxidant enzyme activity, reducing oxidative stress, and improving protein expression related to neurogenesis.by Md.

BackgroundUnintended pregnancy among female sex workers (FSW) is a pressing reproductive health concern attributable to risky sexual behaviors, healthcare inequities and poor negotiation powers with male sex partners. However, evidence is scarce on the prevalence and determinants of unintended pregnancies among FSW, which is crucial for enhancing reproductive healthcare. This analysis aims to measure the prevalence of lifetime unintended pregnancies and their associated factors.
MethodsA cross-sectional study was conducted on 327 FSW in Jashore (a border belt district of Bangladesh) from September 2022 to March 2023. Participants were recruited through take-all sampling. Data were collected on the lifetime history of unintended pregnancies and other relevant variables through face-to-face interviews. Chi-square statistic was used to compare the characteristics of FSW reporting unintended pregnancies. To assess the net association of factors associated with unintended pregnancy, multiple logistic regression was applied.
ResultThe lifetime prevalence of unintended pregnancies was reported at 75.8% (95%CI: 71.0–80.1). Among those who reported unintended pregnancies, 37.1% (95%CI: 30.8–43.8) had no education, 39.9% (95%CI: 32.8–47.5) were 25–34 years old, 49.6% (95%CI: 39.3–59.9) were currently married and 62.9% (95%CI: 49.7–74.4) earned ≤10,000 BDT per month compared to those who did not report lifetime unintended pregnancies. The likelihood of unintended pregnancies was significantly higher among those who reported having sex with non-transactional male sex partners (AOR: 2.4, 95%CI: 1.1–5.3, p = 0.036) than those who never had sex with any non-transactional male sex partner. The likelihood was also higher among those who reported rape in their lifetime (AOR: 2.0, 95%CI: 1.0–3.8, p = 0.037) and who self-reported mental health problems (AOR: 2.1, 95%CI: 1.0–4.2, p = 0.045) within the past year, compared to their counterparts.
ConclusionThis study highlights the considerable prevalence and associated determinants of unintended pregnancies among FSW in Jashore. These determinants need to be considered to strengthen reproductive healthcare interventions and policies for FSW. Reproductive health of FSW cannot be improved unless these factors are addressed in the ongoing interventions.
Necrotising fasciitis (NF) is a rapidly progressing, life-threatening infection with mortality rates that are exceedingly high. Despite the notably high risks of developing NF in patients with diabetes mellitus (DM), factors associated with mortality in this population are poorly understood. Therefore, to determine at-risk patients and to improve overall clinical outcomes via hastening management, the objective of this systematic review is to determine what factors are associated with mortality for diabetic patients with NF. This systematic review followed the PRISMA guidelines. Patient data pertaining to outcomes and surgical management were extracted, and mortality rates were evaluated. Studies were assessed for quality using the Alberta Heritage Foundation for Medical Research (AHFMR) and Risk of Bias tool. A total of 25 studies were reviewed, covering 7879 patients with NF and DM with a 23.5% mortality rate. The most prevalent comorbidities among those who died included chronic kidney disease (15.95%), hypertension (9.42%) and obesity (9.02%). While limbs were the most common location for the disease, NF in the trunk and groin regions showed the highest mortality rates at 62.07%. Among those who died, common complications were acute renal failure (13.41%), pulmonary issues (20.41%) and septicaemia (12.80%). Mortality rates by surgical management were fasciotomy (42.9%), surgical debridement (40.68%) and amputation (9.09%). Mortality was comparable between patients with NF and DM (23.54%) and those with NF alone (23.61%). Although DM may not independently increase mortality, it can worsen outcomes when combined with other comorbidities, indicating a need for clearer clinical guidance.
The Novara Cohort Study (NCS) was established to investigate the biological, psychological and social factors that influence ageing in the general population. The study aims to identify early risk factors for frailty, allostatic load and cognitive decline, and to uncover molecular and functional markers of accelerated biological ageing. NCS addresses the need for detailed life-course data from Southern Europe to support personalised prevention and early diagnosis, and to promote healthy longevity.
NCS is a population-based, longitudinal cohort in the Novara province (Northern Italy), originally enrolling adults aged 35 and older. The inclusion criteria were later expanded to encompass all residents aged 18 and over, facilitating the study of ageing trajectories from early adulthood onward. As of mid-2025, about 1000 participants have been enrolled, and recruitment is ongoing. The cohort’s diversity in age, employment status and health conditions enhances its value for life-course analysis.
Following a pilot phase in 2022–2023, the whole study protocol now includes detailed demographic, clinical, behavioural, cognitive and psychosocial data, along with biological samples stored in the UPO Biobank. The protocol incorporates validated tools, comprehensive physical and cognitive assessments, and over 90 laboratory biomarkers covering inflammation, metabolism, hormonal function and coagulation. Additionally, a subset of participants underwent advanced inflammatory profiling by simultaneous measurement of 92 immune-related proteins and comprehensive genomic profiling using Illumina Single Nucleotide Polymorphism (SNP) arrays, capturing common genetic variation across multiple biological domains. Preliminary results demonstrate the feasibility of integrating deep phenotyping, reveal the roles of frailty in ageing and show initial evidence of age-related changes in inflammatory proteins.
NCS plans to enrol at least 10 000 participants and will conduct long-term follow-up using both passive methods, such as linking with clinical records and administrative health databases, and active in-person reassessments. Future phases will integrate clinical, behavioural and cognitive data with large-scale omics analyses, including genomics, proteomics, metabolomics and transcriptomics. Machine learning techniques will be employed to model biological age, identify early signs of age-related decline and develop personalised prevention strategies. By combining high-resolution phenotyping with multidimensional data, NCS aims to find modifiable risk factors and molecular signatures of ageing, supporting national and European research efforts and encouraging collaborative studies through open data-sharing frameworks.
Cardiovascular diseases (CVDs) are a leading cause of mortality in Nepal. Risk perception is crucial for the prevention of CVD-related behaviours. This study assessed CVD risk perceptions and the stages of preventive behaviours among adults in Pokhara Metropolitan, Nepal by integrating two theoretical models—the Health Belief Model and the Transtheoretical Model.
This study used a cross-sectional design with data collected through a survey using a semistructured questionnaire.
This study was conducted from July 2024 to August 2024; among community people aged ≥20 residing in 11 wards of Pokhara Metropolitan.
A total of 384 community people residing in Pokhara Metropolitan, Nepal.
The primary outcome measure was stage of preventive behaviours of CVDs using Fuster BEWAT components (blood pressure, exercise, weight, diet and tobacco), while explanatory variables were sociodemographic characteristics and CVD Health Beliefs.
A total of 384 adults participated (response rate=95%). The mean age was 42.3 years (SD±14.5), with equal representation of males and females. More than half of the participants (55.5%) perceived low susceptibility to CVDs, 40.4% perceived high severity, 78.4% perceived high benefits and 49.5% perceived moderate barriers. Most respondents were in the precontemplation stage for blood pressure control (43%) and weight management (30.5%), whereas maintenance was most common for physical activity (41.1%), healthy diet (51.3%) and smoking abstinence (80.1%).
Ordinal logistic regression revealed that low perceived benefits significantly hindered behavioural progression (p=0.001–0.012), where low perceived barriers significantly facilitated advancement across all behaviours (p
Perceived benefits and barriers were key predictors of progression in CVD prevention behaviours. While many adults maintained healthy diets, physical activity and smoking abstinence, most were in the early stage for blood pressure and weight control strategies. Strengthening perceived benefits and reducing barriers can enhance the adoption of healthy behaviours in Nepal.
This study aims to describe the characteristics of hospitalised COVID-19 patients in a tertiary care hospital close to an international airport in Japan and to compare these characteristics among different waves during the pandemic.
Retrospective observational study.
Tertiary care centre in Japan.
All patients diagnosed with COVID-19 who were hospitalised between January 2020 and April 2022 were included.
Clinical characteristics, characteristics of admission, treatments and outcomes were investigated and compared among six pandemic waves.
A total of 827 patients were included. The median age was 58.0 years. More than half of the patients (58.3%) had at least one comorbidity. The majority of patients (89.0%) were domestically infected patients admitted under the Infectious Diseases Law, while the remaining patients (11.0%) were those diagnosed during airport quarantine and admitted under the Quarantine Act. Hospital-acquired COVID-19 infection occurred in 7.0% of cases, and mainly during the sixth wave. Overall, some form of oxygen therapy, high-flow oxygen devices, invasive mechanical ventilation (IMV) and extracorporeal membrane oxygenation was provided in 46.3%, 10.4%, 4.5% and 1.5% of cases, respectively. Only 1.8% of patients were treated in the intensive care unit (ICU), and 59.5% of patients on IMV were managed in the non-ICU ward. The in-hospital mortality rate was 5.8%. Median age, percentages of some comorbidities, vaccination coverage, medications for COVID-19, types of supportive care and ICU admissions differed significantly among waves.
This study suggests that patient characteristics, vaccination coverage, standard of treatment and severity of illness changed across waves during the COVID-19 pandemic. Intensive care delivery in non-ICU wards was unavoidable due to limited ICU capacity, which may be a key consideration when preparing for future pandemics.
The COmmunity HEalth System InnovatiON (COHESION) project (2016–2019) was a 4-year collaboration between research teams from Mozambique, Nepal, Peru and Switzerland. It conducted formative health system research using tracer chronic conditions, non-communicable diseases (diabetes and hypertension) and one neglected tropical disease per country (schistosomiasis in Mozambique, leprosy in Nepal and neurocysticercosis in Peru).
Findings guided the co-creation of interventions to improve diagnosis and management through a participatory approach with communities, primary healthcare workers and regional health authorities.
As a continuation of this effort, the research team initiated the COHESION Implementation project (COHESION-I) with two objectives: (1) implement and evaluate the context-specific co-created interventions in Mozambique, Nepal and Peru (Component 1) and (2) adapt the COHESION approach to India, a country that did not benefit from a formative phase previously (Component 2). This protocol manuscript focuses on Component 1.
A mixed-methods, pre–post quasi-experimental design will be used, including quantitative, qualitative, economic and process evaluations. Each country will have three arms: (1) co-created and co-designed interventions; (2) only co-designed intervention and (3) the usual care arm. Data will be collected longitudinally over 18 months to assess the effect of the interventions. The main outcomes include patient satisfaction (Patient Satisfaction Questionnaire Short Form), health system responsiveness (WHO responsiveness domains) and quality of life (EuroQol 5 dimensions 5 levels). The qualitative evaluation will explore how satisfaction is perceived among service users with chronic conditions and healthcare workers. Other outcomes per type of evaluation will be considered such as perceived value of health services, cost estimation and acceptability of the intervention components, among others.
Approvals were obtained from Ethics Committees of Universidad Peruana Cayetano Heredia (Peru), Universidade Eduardo Mondale (Mozambique) and Nepal Health Research Council (Nepal). Results will be disseminated through peer-reviewed publications and scientific conferences.
The study aims to present recommendations for a revised Doctor of Pharmacy (Pharm-D) curriculum that aligns with regional needs and international standards of pharmacy education.
An exploratory qualitative study involving individual semistructured interviews. Data were collected and reported in accordance with Consolidated Criteria for Reporting of Qualitative Studies.
Face-to-face interviews were conducted in the respective offices of the experts and online interviews were conducted on Zoom and Google Meet.
Purposive and snowball sampling was used to recruit experts due to the eligibility criteria of including associate professors with a PhD, and snowball sampling facilitated the recruitment of experts from all provinces and internationally. Interviews were transcribed verbatim and data were analysed using an inductive thematic approach using NVivo V.15. All interviews were conducted in English.
The study engaged 49 experts from national and international settings with an age range of 25–60 years (median=43 years). The researchers came out with six themes and their subthemes from the data including: (a) understanding current Pharm-D curriculum in Pakistan, (b) inevitable changes required in the Pharm-D curriculum, (c) specific-subject based changes, (d) foundational steps to achieve the required changes, (e) barriers to the implementation of these changes and (f) impact of Pharm-D curriculum change.
The findings highlighted a clear need to revise the curriculum by incorporating enhanced clinical pharmacy content, integrated learning approaches, elective courses, interprofessional education, mandatory hospital and clinical placements, experiential learning through simulation-based methods and research components through a collaborative approach from policy makers and academic stakeholders.
Binge drinking in the previous month was reported in 23.5% of US adults, and 28.1 million adults met criteria for Alcohol Use Disorder (AUD) in 2023. Individuals with AUD face increased risks of oral health problems, including caries, periodontal disease and mucosal lesions. Poor oral hygiene, nutrition and dental care all contribute to these conditions, but individuals with AUD are often under-represented in oral health surveys. Understanding relationships between oral health behaviours, attitudes and general health is crucial for designing future interventions. This pilot aims to explore the relationship between oral and systemic health in subjects with AUD, focusing on oral health behaviours, salivary biomarkers and clinical phenotype, including systemic biomarkers of inflammation, to inform future research on oral–systemic interactions in AUD.
This protocol has two parts. Part 1 involves cognitive interviews to assess the content validity and interpretability of the Oral Health Behaviours Assessment (OHBA) questionnaire. Part 2 will collect biological and behavioural data from treatment-seeking patients with AUD and matched controls (age, sex and smoking status), including saliva, blood, dental exams, and health behaviour and symptom measures. Inpatients with AUD will provide biospecimens and answer symptom severity questionnaires at admission and again at the dental exam visit (7–12 days later), while controls will provide a single set of measures at their dental exam visit. Oral health will be assessed through structured dental and periodontal examinations, radiographs and validated questionnaires (including the OHBA). Additional data will include alcohol use history, psychiatric and medical history assessments, dietary recall, and measures of stress, sleep and mood to capture potential moderators of oral–systemic relationships. Biomarkers of inflammation and stress will be quantified from saliva and blood using immunoassays. Primary outcomes will compare oral health, salivary biomarkers and clinical measures between AUD and controls, while secondary outcomes will evaluate within-subject changes in patients with AUD during inpatient treatment and early abstinence.
This clinical protocol was approved by the National Institutes of Health Institutional Review Board (IRB #002005). Prior to enrolling, participants will be informed of the study purpose, risks and benefits, and study procedures, and evaluated for understanding prior to signing consent. Part 1 of the protocol is currently active and recruiting participants for cognitive interviews. The study findings will be disseminated through journals and conferences related to addiction medicine, psychology, immunology, neuroscience and dentistry. We expect the results of the pilot study will inform future research on oral health and salivary bioscience while also providing treatment-seeking patients with AUD targeted information on the importance of oral health behaviours for maintaining oral and systemic health.

Ternary complex of curcuminoid-rich extract (CRE-Ter) is a developed water-soluble Curcuma longa extract containing 14% w/w curcuminoids, hydroxypropyl-β-cyclodextrin, and polyvinylpyrrolidone K30. This study aimed to investigate the biomolecular effects of CRE-Ter on differentiation of bone cells (murine MC3T3-E1 preosteoblasts), muscle cells (murine dexamethasone-treated C2C12 myotubes) atrophy and irisin expression. In MC3T3-E1 preosteoblasts, CRE-Ter treatment increased alkaline phosphatase activity, calcium deposition, and expression of Bmp-2, Runx2, and collagen 1a significantly and dose-dependently. 5, 10, and 20 µg/mL CRE-Ter upregulated β-catenin expression significantly. CRE-Ter improved the atrophy of dexamethasone-treated C2C12 myotubes. CRE-Ter decreased proinflammatory cytokine (TNF-α and IL-6) expression but increased FNDC5 and irisin expression and nitric oxide production in dexamethasone-treated C2C12 myotubes significantly and dose-dependently. Dexamethasone promoted β-catenin and total p38 expression in C2C12 myotubes. CRE-Ter at 2.5–20 µg/mL reversed the increase in β-catenin expression, whereas 2.5 µg/mL reversed total p38 expression. Crosstalk experiments further revealed that conditioned medium from C2C12 myotubes enhanced osteocalcin expression in MC3T3-E1 osteoblasts. Molecular docking simulations using CB-Dock2 showed strong interactions between each curcuminoid molecule and irisin. Therefore, CRE-Ter may stimulate osteoblast differentiation, ameliorate myotube atrophy, and increase irisin expression, indicating its therapeutic potential in osteoporosis, sarcopenia, and osteosarcopenia.Predicting the progression to severe dengue remains a critical yet challenging aspect of patient management. This umbrella review aims to identify biomarkers associated with the development of severe dengue. The primary objective is to determine which biomarkers can predict progression to severe disease in dengue-infected patients. Secondary objectives include identifying (a) early biomarkers (detected on days 1–3 of illness), (b) late biomarkers (detected after day 3), (c) biomarkers requiring further investigation and (d) differences in predictive biomarkers between patients aged
The review questions were formulated based on the Population, Concept and Context (PCC) framework. This review will follow the Joanna Briggs Institute methodology for umbrella reviews and be reported in accordance with the Preferred Reporting Items for Overviews of Systematic Reviews guidelines. The protocol has been registered in PROSPERO (CRD420251058284). MEDLINE, Embase, CINAHL, Cochrane Database of Systematic Reviews, JBI Evidence Synthesis and DARE databases will be searched from 1/1/1990 to 1/6/2025. The findings are expected to support early risk stratification and guide future biomarker research in dengue infection. The systematic reviews included in this umbrella review may define severe dengue according to either the WHO 1997 or 2009 guidelines.
Ethical approval is not required since the work involves published documents. The review findings will be communicated to relevant stakeholders through conference presentations and publication in an open-access journal.

Bacillus Calmette-Guérin cell wall skeleton (BCG-CWS) has been shown to enhance vaccine effectiveness and antitumor immunity. In our previous study, we reported that co-administration of BCG-CWS with the encapsidated dengue antigens, UV-inactivated DENV2 and DENV2 NS1, synergistically induced DENV-specific adaptive immune responses in mice. As dendritic cells (DCs) are key immune players that mediate innate and adaptive immunity, we, here, asked how well the response of DCs to this adjuvant aligns with the immune responses elicited in vivo. The responses of primary monocyte-derived DCs to BCG-CWS-adjuvanted encapsidated dengue immunogens compared with the unadjuvanted vaccine were investigated. DCs stimulated by BCG-CWS and the dengue nanoparticle vaccine exhibited a superior response. This response correlated well with the stronger immune response observed in mice. This was evidenced by the marked elevation in expression levels of DC activation markers, such as CD80, CD83, CD86, and HLA-DR, and various innate immune cytokines. Additionally, this adjuvant markedly elevated the expression levels of miRNAs related to DC function, such as miR-146a, miR-147, miR-223, and miR-155. These immune components could suppress DENV2 multiplication in bystander skin cells. BCG-CWS exerted an adjuvant effect on DC responses by enhancing antigen-processing activity and activating several innate immune cytokines and immune-related miRNAs.Implementation science (IS) is increasingly recognised as vital in cancer control planning and integrating evidence-based interventions across the cancer care continuum. Contextual differences often cause variability in delivering optimised healthcare, which IS approaches could mitigate. While IS improves planning effectiveness, many programme and policy planners remain unaware of its benefits. To address this, we examined IS theories applied to national cancer control plans (NCCPs)/strategies across five domains: stakeholder engagement, situational analysis, capacity assessment, economic evaluation and impact assessment.
We conducted a scoping review using the Arksey and O’Malley framework to analyse NCCPs and strategies from 16 and 17 countries belonging to low and medium categories of Human Development Index (HDI), focusing on resource-constrained settings. We identified plans through the International Cancer Control Partnership portal, categorised them by WHO region and included only those available in English or French. We extracted data into a Microsoft Excel database and performed thematic analysis across five IS domains. Multiple IS experts, selected purposively based on their familiarity with resource-constrained settings, validated the findings, assessed policy relevance and helped develop a pathway for integrating IS into national cancer control planning. They reviewed structured questions in advance and provided feedback on analyses, practical utility, dissemination and simplifying IS application, which was used to refine the pathway and reach consensus.
While many NCCPs incorporated key IS elements such as stakeholder engagement, situational analysis and impact measurement, these often needed to be more explicit and consistently applied. None of the plans assessed health system capacity to determine readiness for implementing new interventions. Although most plans described stakeholder engagement, it was typically unstructured and incomplete. Four low HDI and nine medium HDI countries included costed plans, generally using an activity-based approach. All plans included impact measures (eg, key performance indicators), but five lacked mechanisms for engaging stakeholders or responsible entities to achieve the targets. These findings informed a proposed pathway to integrate IS principles into cancer control planning.
Integrating IS into national cancer control planning offers a structured framework for achieving equitable and feasible cancer control policies, particularly in resource-constrained settings, by enabling realistic goal setting and benchmarking against regional and global standards.
Patient safety culture plays a crucial role in reducing clinical errors. By improving healthcare professionals’ and patients’ understanding of human fallibility and error attribution, patient care can be enhanced, fostering greater engagement from both groups. A Just Culture approach, which balances accountability and learning from errors, is a key factor in fostering this safety culture. The DECIDE Project aims to: (1) examine the conceptualisation of human fallibility within and beyond healthcare, (2) identify barriers and facilitators to Just Culture adoption, (3) assess the impact of psychoeducational interventions on professionals’ and social leaders’ attitudes toward clinical errors and (4) develop a roadmap for Just Culture implementation in healthcare.
A 36-month mixed-methods study including qualitative research, a survey of 1255 healthcare professionals, an experimental study with 180 participants (60 per arm) testing interventions based on cognitive dissonance and reasoned action theories and a consensus conference to develop a Just Culture roadmap. Participants include professionals from hospitals, primary care, long-term care, nursing homes and social leaders in Spain. The qualitative data collected during stages 1 and 4 will be analysed using MAXQDA software. In identifying factors related to the implementation of Just Culture during stage 2, ANOVA, t-tests and multiple linear regression will be conducted. To examine the effects of the interventions in phase 3, a linear mixed-effects model for repeated measures will be employed.
This study has received ethical approval from three institutional review boards. Findings will be disseminated through peer-reviewed publications, conference presentations and policy recommendations aimed at integrating Just Culture into national and international patient safety strategies. By promoting a constructive approach to errors, the project could enhance incident reporting, strengthen professional engagement in safety policies and foster a culture of learning and accountability. Its findings will guide policy recommendations for integrating Just Culture into national and international patient safety strategies, with potential applications beyond Spain.
The rise of electronic nicotine delivery systems (ENDS) has introduced new challenges to tobacco control and regulation, particularly among young adults, raising questions about their safety. This umbrella review aimed to synthesise existing systematic reviews with or without meta-analyses to evaluate the health impacts of ENDS.
We conducted a systematic literature search via the PICO strategy across multiple databases, focusing on e-cigarettes, ENDS and e-liquids, while excluding non-nicotine e-cigarette and nicotine replacement therapies (NRTs). Health outcomes include a range of clinical diseases and physiological changes. Quality assessment was performed via assessing the methodoligcal quality of systematic reviews 2 (AMSTAR-2), and the findings were synthesised narratively and in tables, prioritising the highest-rated reviews. The meta-analyses used R software (V.4.3) random effects models, and evidence quality was assessed via the Grading of Recommendations, Assessment, Development and Evaluation criteria.
Of the 5055 records, 69 systematic reviews were included. Systematic reviews have indicated increased risks of cardiovascular and respiratory diseases, mental health issues and substance abuse with ENDS use, especially among adolescents. Cardiovascular risk factors included increased heart rate (mean difference (MD) 1.41, 95% CI 0.81 to 2.01, I2=91%) from 25 studies; increased blood pressure (MD for systolic blood pressure=0.51 mm Hg, 95% CI 0.26 to 0.75, I2=89%; MD for diastolic blood pressure=0.59 mm Hg, 95% CI 0.35 to 0.83, I2=82%) from 23 studies; endothelial dysfunction and increased platelet activity. Respiratory risk factors included reduced lung function and a higher incidence of asthma in nine studies (OR 1.30, 95% CI 1.1 to 1.55; I2=43%) and chronic obstructive pulmonary disease. Mental health concerns, such as depression and suicidality, were also prevalent among adolescent ENDS users. Nine studies reported a negative effect of ENDS on periodontal health. Evidence of carcinogens has been found in the urinary examinations of ENDS users in some studies. The adverse events reported in seven randomised controlled trials with 2611 participants were similar between ENDS and NRT (RR 1.13, 95% CI 0.83 to 1.54, I2=12%).
Exposure to ENDS is harmful to various organ systems, especially cardiovascular and respiratory systems. Comprehensive regulatory measures and public health strategies are necessary to curb the use of ENDS, particularly among young people.
Commentary on: Hua Y, Lu H, Dai J, et al. Self-management challenges and support needs among patients with primary glaucoma: a qualitative study. BMC nursing. 2023 Nov 14;22(1):426.
Healthcare professionals should provide personalised and comprehensive support, addressing the medical, emotional and social challenges faced by patients with primary glaucoma. Further research is needed to explore the effectiveness of tailored self-management support programmes in improving the quality of life and treatment outcomes for patients with glaucoma.
Glaucoma is a chronic disease characterised by progressive visual field defects. It is the most common cause of irreversible blindness and is associated with a decrease in quality of life.
In Bangladesh, evidence on the long-term trajectory of adolescents' sexual and reproductive health (SRH) remains limited, largely due to the lack of longitudinal data to assess the changes over time. To address this gap, the Advancing Sexual and Reproductive Health and Rights (AdSEARCH) project of International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) set up an adolescent cohort study aimed at documenting changes in SRH knowledge, attitudes and practices, and identifying the factors affecting these changes. This article presents the baseline sociodemographic and SRH characteristics of this cohort as a pathway for future analyses.
This cohort study included 2713 adolescents from the Baliakandi Health and Demographic Surveillance System run by icddr,b. The cohort covered three age groups from girls and boys, giving a total of five cohorts: girls aged 12, 14 and 16 years; and boys aged 14 and 16 years. A total of seven rounds of data had been collected at 4-month intervals over 2-years follow-up period.
The majority of adolescents were attending school (90%), and school dropouts were higher among boys. Around 17% of the respondents were involved in income-generating activities, which were mostly boys. Among girls, the mean age of menarche was 12.2 years. Overall, 6% of adolescents had major depressive disorder, with prevalence increasing with age. Gender differences were evident regarding knowledge about conception and contraception. Egalitarian attitudes towards social norms and gender roles were found higher among girls (52%) compared to boys (11%). The majority of adolescents reported experiencing social/verbal bullying (43%), followed by physical violence (38%) and cyberbullying (4%).
This article presents the baseline findings only. A series of papers is in the pipeline for submission to different peer-reviewed journals. The findings from this study will be used to support data-driven policy formulation for future adolescent health programmes.
This paper examines the impact of India’s National Publicly Funded Health Assurance Scheme, Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (PM-JAY), in Haryana on out-of-pocket (OOP) expenses and catastrophic health expenditure (CHE).
We conducted a case-control study using a stratified random sampling approach.
Six districts in Haryana, based on utilisation, were selected: Mewat, Faridabad, Sonipat, Ambala, Kurukshetra and Karnal.
A total sample size of 772 individuals, that is, 386 PM-JAY beneficiaries (cases) and non-beneficiaries (controls) each.
Data were collected using a semistructured questionnaire covering household demographics and expenditure details. The interview gathered information on hospitalisation within the past year, types of ailments, the type of empanelled facility visited, expenditure details and borrowing/selling of assets for treatment.
Mean OOP expenditure was calculated for beneficiaries and non-beneficiaries based on the type of healthcare provider. The impact of PM-JAY on OOP expenditure was analysed using a generalised linear model controlling for religion, caste, type of house, type of family, morbidity patterns, type of disease, type of health facility, hospital stay duration, average distance to the facility and travel time. CHE was defined as OOP payments ≥30% of household income. Logistic regression was used to assess the determinants of CHE.
We found that direct medical expenses incurred for hospitalisations were 65% lower for beneficiaries (11 131 rupees) compared with non-beneficiaries (31 675 rupees). While OOP expenditures are similar for both groups in public empanelled hospitals, non-beneficiaries incur OOP costs three times higher than PM-JAY beneficiaries in private empanelled hospitals. Factors, including the disease type, average distance from home to the facility, average travel time and type of hospital, significantly influence these expenses. Furthermore, the prevalence of CHE is significantly lower among PM-JAY beneficiaries (13.3%) compared with non-beneficiaries (45.9%), with an OR of 7.15 (95% CI: 4.74 to 10.80; p
Our analysis shows the scheme’s impact on decreasing OOP expenditure and CHE. To enhance the scheme’s effectiveness, the study highlights the necessity of addressing non-medical expenses and expanding coverage for indirect costs, such as food, accommodation and transportation. Additionally, strengthening the supply side through improved drug availability at healthcare facilities is crucial for enhancing financial protection and access to care.
Medical oxygen supplementation is essential for treating severe illnesses and plays a critical role in managing life-threatening conditions, especially during the period of increased demand, such as the delta wave of COVID-19. The study aims to evaluate oxygen requirements and production to support effective capacity planning for future health crises.
Cross-sectional quantitative study. Data collection was carried out between 15 March and 19 December 2021.
The study used secondary data from Nepal’s Health Emergency Operation Centre. Regarding medical oxygen production, calculations included oxygen generated from both hospital-based oxygen plants and private companies, using their highest capacities for comparison. These production capacities were then assessed using three levels of efficiency (100%, 80% and 50%), revealing significant gaps when compared against the oxygen requirements of hospitalised COVID-19 patients, as guided by WHO recommendations. The results were communicated in terms of J-size cylinders, alongside average daily COVID-19 hospitalizations. Data was inputted and analysed using Microsoft Excel and presented in numbers and percentage.
The country’s oxygen demand relies largely on the production from private enterprises, with meeting approximately 85.2% of the total requirement. Optimal production ensures that national oxygen needs will be met. The analysis highlighted that at 80% operational efficiency, 90.8% of the hospital’s requirements could be fulfilled. However, if operational efficiency drops to 50%, the fulfilment rate diminishes to 56.7%. The differences in requirement and production of oxygen are consistent across the provinces; however, a huge disparity was notable in Karnali and Sudurpaschim.
Continuous assessment of production capacities in both hospital and private enterprises producing oxygen is necessary to plan and address the gaps.
Multimorbidity contributes significantly to poor population health outcomes while straining healthcare systems. Although some multimorbid patients experience an accelerated health decline (a decline in well-being or functional status that cannot be attributed to the natural ageing-related health deterioration), others can remain stable for years. Identifying risk factors for accelerated health decline in persons with multimorbidity could help prevent complications and reduce unnecessary interventions. Our review, therefore, aims to map the evidence on the clinical, biographical and healthcare-related factors associated with an accelerated health decline in multimorbid individuals.
We will use the evidence-mapping review methodology. We will perform a systematic comprehensive literature search in Medline via Pubmed, Cochrane Library, EMBASE, Web of Science and Google Scholar using two broad concepts: ‘multimorbidity’ and ‘longitudinal studies’. We will search with MeSH terms (eg, ‘Multimorbidity’ (Majr), ‘Longitudinal Studies’ (Majr)) and free text words (eg, multimorbidity, multiple chronic condition*, longitudinal), from inception to date of the final search. All original quantitative studies involving participants in primary care and related healthcare settings will be included. Abstract/titles and full-text screening and data extraction will be performed independently by two or more researchers to minimise selection and reporting bias, with conflicts resolved by consensus. The data will be analysed qualitatively, and topics will be extracted to create evidence clusters. Risk factors will be classified in groups and cross-referenced against the outcomes from respective studies into combinations of exposure-outcome clusters. The resulting evidence clusters will be described narratively and presented as bubble plots. The search, initiated in January 2023, will be updated following this protocol review to reflect the most current evidence; exact dates will be reported in the results manuscript.
Due to the nature of the proposed evidence map, ethics approval will not be required. Results from our research will be disseminated through publications in peer-reviewed journals and presentations at local, national and international conferences.
