by Thomas C. Scheier, Richard Whitlock, Mark Loeb, Philip James Devereaux, Andre Lamy, Michael McGillion, MacKenzie Quantz, Ingrid Copland, Shun-Fu Lee, Dominik Mertz

Sternal surgical site infections after cardiac surgery can lead to significant morbidity, mortality, and cost. The effects of negative pressure wound management and adding vancomycin as perioperative antimicrobial prophylaxis are unknown. The PICS-PREVENA pilot/vanguard trial, a 2x2 factorial, open label, cluster-randomized crossover trial with 4 periods, was conducted at two major cardiac surgery hospitals in Ontario, Canada. Sites were randomized to one of eight sequences of the four study arms (Cefazolin or Cefazolin + Vancomycin (not analyzed) and standard wound dressing or a negative pressure 3M Prevena incision management system (Prevena). Only diabetic or obese patients were eligible for the latter comparison. This trial investigated feasability including adherence to protocol of each intervention (goal: > 90% each) and loss to follow-up (goal:

Drug-resistant (DR) tuberculosis (TB) and diabetes mellitus (DM) are intersecting epidemics that complicate management of both diseases and worsen patient outcomes. We conducted a prospective cohort study of 758 GeneXpert-confirmed pulmonary TB patients, of whom 75 had DM. Demographic, clinical, radiographic, and anthropometric data were collected at baseline. Sputum samples were cultured for mycobacterial isolation, and the obtained isolates were characterized for Mycobacterium tuberculosis complex (MTBC) lineage and drug-susceptibility testing using spoligotyping and microplate alamar blue assay. The TB-diabetes (TB-DM) comorbid cohort was older [TB-DM: 53/75 (70.7%) vs. 241/683 (35.3%) aged 41–60 years) (p

Health risk realization versus warning: Impact on lifestyle behaviours

Por: Zoey Verdun — Diciembre 15th 2025 at 15:00

by Zoey Verdun

Using individual-level panel data from Understanding Society I estimate the response to a health risk realization on a healthy lifestyle index. To overcome the endogeneity of a diagnosis, I match on initial health risks. I find individuals improve their overall lifestyle healthiness when faced with a large negative health event such as a heart attack or diabetes diagnosis, interpreted as a precise signal about their health status, whereas they do not respond to a noisier signal through solely receiving information about certain health risk factors, such as a diagnosis of high blood pressure or angina (chest pain). The drivers of the overall effect are a decrease in the number of cigarettes smoked and an increase in not drinking alcohol; there is no significant effect found for either diet or exercise. I find some heterogeneity by sex, but only when looking at individual lifestyle behaviours. Overall, the findings suggest that the realization of a health risk leads individuals to improve their lifestyle behaviours, while only a noisier signal about their health risks leads to no such change.

Organising maternal and newborn care in high-income countries: a scoping review of organisational elements and their association with outcomes

Por: Liebregts · J. · Goodarzi · B. · Valentijn · P. · Downe · S. · Erwich · J. J. · Burchell · G. · Batenburg · R. · de Jonge · A. · Verhoeven · C. J. M. · VOICE Study Group · Burzynska · de Graaf · van Heemstra · Rippen · Koster · van der Voort · Kaiser · Fransen · Berks · Haga · Vermo — Diciembre 15th 2025 at 06:41
Introduction

Countries face challenges in maternal and newborn care (MNC) regarding costs, workforce and sustainability. Organising integrated care is increasingly seen as a way to address these challenges. The evidence on the optimal organisation of integrated MNC in order to improve outcomes is limited.

Objectives

(1) To study associations between organisational elements of integrated care and maternal and neonatal health outcomes, experiences of women and professionals, healthcare costs and care processes and (2) to examine how the different dimensions of integrated care, as defined by the Rainbow Model of Integrated Care, are reflected in the literature addressing these organisational elements.

Results

We included 288 papers and identified 23 organisational elements, grouped into 6 categories: personal continuity of care; interventions to improve interdisciplinary collaboration and coordination; care by a midwife; alternative payment models (non-fee-for-service); place of birth outside the obstetric unit and woman-centred care. Personal continuity, care by a midwife and births outside obstetric units were most consistently associated with improved maternal and newborn outcomes, positive experiences for women and professionals and potential cost savings, particularly where well-coordinated multidisciplinary care was established. Positive professional experiences of collaboration depended on clear roles, mutual trust and respectful interdisciplinary behaviour. Evidence on collaboration interventions and alternative payment models was inconclusive. Most studies emphasised clinical and professional aspects rather than organisational integration, with implementation barriers linked to prevailing biomedical system orientations.

Conclusions

Although the literature provides substantial evidence of organisational elements that contribute to improved outcomes, a significant gap remains in understanding how to overcome the barriers in sustainable implementation of these elements within healthcare systems. Interpreted through a systems and transition science lens, these findings suggest that strengthening integrated maternity care requires system-level changes aligning with WHO policy directions towards midwifery models of person-centred care.

Determining the longitudinal associations between suicidal ideation and biopsychosocial factors in early to mid-adolescence: a prospective cohort study

Por: Crethar · M. · Boyes · A. · Schwenn · P. · Mills · L. · Prince · T. · Bromley · K. · Kennedy · M. · Driver · C. · Hermens · D. F. — Diciembre 12th 2025 at 18:11
Objectives

To determine whether a biopsychosocial model of suicidality, specifically sleep, nutrition, physical exercise, mindfulness, social connectedness, lower socioeconomic status (SES) and sex are uniquely associated with increased suicidal ideation, longitudinally over adolescence.

Design

Longitudinal, prospective cohort study.

Setting

A structured self-report questionnaire was collected as part of the Longitudinal Adolescent Brain Study at the University of the Sunshine Coast’s Thompson Institute (Queensland, Australia) from July 2018 to January 2024.

Participants

159 Australian adolescents (n=91 female; 68 male) aged 12 to 17 years.

Outcome measures

Self-reported suicidal ideation was measured longitudinally. Data were also collected on self-reported lifestyle factors (sleep, nutrition, physical exercise, mindfulness and social connectedness), psychological distress, SES and sex. All measures were collected at 4-monthly intervals for each participant for up to 5 years (maximum of 15 time points).

Results

Significant relationships were identified between increased suicidal ideation and poor sleep (OR 2.6, 95% CI 1.4 to 4.6, p=0.002), socioeconomic disadvantage (SES quintile 1: OR 6.3, 95% CI, 1.8 to 21.8, p=0.004; SES quintile 2: OR 8.7, 95% CI 1.4 to 56.2, p=0.022), psychological distress (OR 5.7, 95% CI 2.1 to 15.6, p≤0.001) and eating habits (β –0.08, 95% CI –0.2 to –0.0).

Conclusions

Poor sleep, socioeconomic disadvantage, psychological distress and eating habits were all found to be significantly associated with increased adolescent suicidal ideation over time. These biopsychosocial factors should be considered in targeted interventions and policies for reducing adolescent suicidality. Further research should employ multilevel modelling to examine factor interactions and rigorously evaluate interventions targeting lifestyle factors and socioeconomic inequalities through randomised controlled trials and quasi-experimental designs.

Sources and consequences of self-doubt in patients with Ehlers-Danlos syndrome: a qualitative study in Europe and North America

Por: Halverson · C. M. E. · Vershaw · S. L. · Francomano · C. A. · Doyle · T. — Diciembre 12th 2025 at 18:11
Objectives

To examine how clinicians’ scepticism regarding patients’ self-reports of subjective symptoms can be internalised, leading to psychosocial and medical harms.

Design

In-depth, semi-structured qualitative interviews with the resulting data analysed using reflexive thematic analysis.

Participants

43 individuals with Ehlers-Danlos syndrome (EDS) from Europe and North America completed a pre-survey, and 39 of those participants completed interviews for this study. Purposive sampling was used to obtain approximately equal numbers of participants with hypermobile EDS and the molecularly defined types of EDS.

Results

Patients with both hypermobile and molecularly defined types of EDS reported high levels of self-doubt, with 73% of survey respondents questioning the extent—and even reality—of their private experiences of pain. Participants attributed much of their self-doubt to repeated dismissal and minimisation of their symptoms in healthcare settings, especially during childhood. Ultimately, self-doubt transformed not merely how they communicated their symptoms but also how they recognised, evaluated and even experienced them at a phenomenological level. While some participants developed coping strategies, others withdrew from the conventional medical system altogether.

Conclusion

These findings have important implications for clinicians, who may inadvertently reinforce self-doubt through discussion of diagnostic uncertainty. Doubt need not be delegitamising. Recognising and mitigating these potential harms requires epistemic humility and attention to the psychosocial dynamics of patient-provider interaction.

Perspective of healthcare professionals on barriers and facilitators in exploring end-of-life care preferences of patients with pulmonary fibrosis: A qualitative study

Por: Lian Trapman · Lea M Dijksman · Jan C. Grutters · Saskia C.C.M. Teunissen · Everlien de Graaf — Diciembre 12th 2025 at 15:00

by Lian Trapman, Lea M Dijksman, Jan C. Grutters, Saskia C.C.M. Teunissen, Everlien de Graaf

Background

Progressive pulmonary fibrosis is a lethal disease with a survival of 3–5 years with optimal medication treatment. Palliative care and advance care planning are therefore receiving increasing attention in the literature. However, structural implementation in clinical practice is still lacking. The aim of this study was to explore the needs, facilitators, and barriers for communication on the topic of end-of-life preferences of patients from the perspective of healthcare professionals.

Methods

A generic qualitative study was performed with focus groups and individual semi structured interviews with healthcare professionals. Data collection and analysis were performed iteratively. A thematic analysis was performed, following the methods of Braun and Clarke.

Results

Three focus groups and seven individual semi-structured interviews were conducted. Three themes were generated: (1) a lack of vision on palliative care, resulting in different approaches within the same clinic and showing the need for optimization of collaboration; (2) the importance of a learning-driven environment to support healthcare professionals skills and knowledge; and (3), the central role of the individual professional in developing skills and knowledge.

Conclusions/discussion

This study underscores the importance of behavioral and organizational change in palliative care to optimize conversations exploring values, preferences, and needs for end-of-life care for patients with pulmonary fibrosis. Leveraging the shared motivation of healthcare professionals to provide optimal care, integrating these findings into training and coaching programs can further enhance patient-centered approach in palliative care.

Drug-related stigma among people who inject drugs – development and validation of the drug use stigma scale (DUSS)

Por: Robin A. Pollini · Catherine E. Paquette · Brandon Irvin · Jennifer L. Syvertsen · Christa L. Lilly — Diciembre 12th 2025 at 15:00

by Robin A. Pollini, Catherine E. Paquette, Brandon Irvin, Jennifer L. Syvertsen, Christa L. Lilly

Drug use is a highly stigmatized behavior, and drug-related stigma is a key driver of behavioral risk, lower health care utilization, and associated adverse health outcomes among people who inject drugs (PWID). While instruments exist for measuring drug-related stigma, their applicability to community-based PWID across multiple stigma types (enacted, anticipated, internalized) and settings (health care, society, family) is limited, as most were developed using treatment-based samples and all were developed in urban populations. This study sought to develop a Drug Use Stigma Scale (DUSS) that addresses these limitations. We developed an initial list of 39 items based on literature review and qualitative interviews (N = 27) and three focus groups (N = 28) with PWID recruited from syringe services programs and via peer referral in two predominantly rural West Virginia counties. The scale items were administered in a survey to 336 PWID recruited from the same two counties divided into development and validation samples. Responses to the 39-item scale went through a multidimensional refinement process, including examination of internal consistency, Confirmatory Factor Analysis (CFA), and a three-factor CFA based on stigma setting. Next, a set of final measurement CFAs were conducted. Finally, the resulting scale was examined for criterion-related concurrent validation. The final DUSS consisted of 16 items with excellent fit statistics for the development sample: SRMR: 0.03, RMSEA: 0.09, GFI: 0.92, CFI: 0.96, NFI: 0.94. Fit attenuated but remained satisfactory for the validation sample. DUSS scores were significantly associated with increased odds of not seeking healthcare when needed (OR: 1.47, p = 0.001; OR: 1.61, p

Sexual and reproductive health policies for migrant, immigrant and refugee populations in select high-income countries: a policy analysis protocol

Por: Mirzaei Damabi · N. · Castleton · P. · Mengesha · Z. · Munn · Z. · Begum · M. · Avery · J. · Meherali · S. · Lassi · Z. — Diciembre 10th 2025 at 11:59
Introduction

International migrants comprise 3.6% of the global population and face systemic barriers to accessing sexual and reproductive health (SRH) services, such as contraception, safe abortion care and sexual function support. In high-income countries, policy frameworks vary widely, with migration status significantly influencing entitlement and access to host countries. This protocol outlines a planned study to systematically analyse SRH policies in high-income countries with strong migrant integration frameworks, aiming to identify policy gaps, assess inclusivity and inform recommendations to strengthen Australia’s SRH policy landscape.

Methods and analysis

This study employs a systematic policy analysis using the Joanna Briggs Institute scoping review methodology. Countries with ≥10% migrant populations and a Migrant Integration Policy Index health score ≥70 will be included. 13 countries meet these criteria, including Australia, Canada and Sweden. A comprehensive search of academic databases (PubMed, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature and ProQuest Public Health) and grey literature from governmental and non-governmental sources will be conducted. Data extraction will follow Bacchi’s ‘What’s the Problem Represented to Be?’ approach. Thematic analysis will combine deductive and inductive methods to examine the extent to which SRH policies address migrant and refugee needs, including sexual function, safe abortion care and fertility care. A comparative policy matrix will identify strengths, limitations and best practices.

Ethics and dissemination

As this study analyses publicly available policy documents, ethics approval is not required. Findings will be disseminated through peer-reviewed publications and policy briefs targeting stakeholders involved in SRH policy and migrant health.

S. · Probasco · J. · Hasbun · R. · Bea — Diciembre 8th 2025 at 06:09
Objective

Encephalitis is brain parenchyma inflammation, frequently resulting in seizures which worsens outcomes. Early anti-seizure medication could improve outcomes but requires identifying patients at greatest risk of acute seizures. The SEIZURE (SEIZUre Risk in Encephalitis) score was developed in UK cohorts to stratify patients by acute seizure risk. A ‘basic score’ used Glasgow Coma Scale (GCS), fever and age; the ‘advanced score’ added aetiology. This study aimed to evaluate the score internationally to determine its global applicability.

Design

Patients were retrospectively analysed regionally, and by country, in this international evaluation study. Univariate analysis was conducted between patients who did and did not have inpatient seizures, followed by multivariable logistic regression, hierarchical clustering and analysis of the area under the receiver operating curves (AUROC) with 95% CIs.

Participants and setting

2032 patients across 13 countries were identified, among whom 1324 were included in SEIZURE score calculations and 970 were included in regression modelling. The involved countries comprised 19 organisations spanning all WHO regions.

Outcome measures

The primary outcome was measuring inpatient seizure rates.

Results

Autoantibody-associated encephalitis, low GCS and presenting with a seizure were frequently associated with inpatient seizures; fever showed no association. Globally, the score had limited discriminatory ability (basic AUROC 0.58 (95% CI 0.55 to 0.62), advanced AUROC 0.63 (95% CI 0.60 to 0.66)). The scoring system performed acceptably in western Europe, excluding Spain, with the best performance in Portugal (basic AUROC 0.82 (95% CI 0.69 to 0.94), advanced AUROC 0.83 (95% CI 0.72 to 0.95)).

Conclusions

The SEIZURE score performed best in several countries in Western Europe but performed poorly elsewhere, partly due to differing and unknown aetiologies. In most regions, the score did not reach a threshold to be clinically useful. The Western European results could aid in designing clinical trials assessing primary anti-seizure prophylaxis in encephalitis following further prospective trials. Beyond Western Europe, there is a need for tailored, localised scoring systems and future large-scale prospective studies with optimised aetiological testing to accurately identify high-risk patients.

Determinants and implementation strategies to implement a reflection method for guideline-based informal caregiving in community nursing in the Netherlands: a mixed-method study

Por: Vullings · N. · Maas · M. · Adriaansen · M. · Vermeulen · H. · Van der Wees · P. · Heinen · M. — Diciembre 5th 2025 at 09:25
Aim

This study aims to identify key determinants and strategies for effectively implementing a reflection method to support adequate use of the ‘Informal Care’ guideline within community nursing. The SPARK (Self & Peer Assessment to Reflect on Quality Standards) reflection method, developed in an earlier participatory design-based study, is a structured group reflection approach designed to help nurses and nursing assistants reflect on and apply guideline recommendations in daily practice.

Design

A mixed method study.

Setting

Six community care organisations in the Netherlands.

Participants and interventions

This mixed-method study collected qualitative data through observations and video recordings of group meetings with community nurses, nursing assistants and a patient representative, alongside quantitative questionnaires. This project included design and test group meetings to develop and evaluate prototypes of the reflection method. Observations were discussed, and video recordings were thematically analysed. The Measurement Instrument for Determinants of Innovations questionnaire was used to identify key determinants for effective implementation. The questionnaire results were analysed descriptively, using the Tailored Implementation in Chronic Diseases (TICD) framework to present preliminary determinants for validation. Implementation strategies were then selected in a group meeting. Based on this input, the research group operationalised the selected implementation strategies.

Results

Twenty-nine determinants for implementing the reflection method were identified across seven TICD domains, including barriers such as limited support, knowledge and time, and facilitators such as team collaboration and prevention of caregiver overload. Based on these findings, three implementation strategies, namely knowledge enhancement, coaching development and leadership strengthening, were formulated to support integration into community nursing practice.

Conclusion

This study identified key determinants and strategies for implementing a reflection method in community nursing. While several determinants align with existing literature, context-specific determinants related to the heterogeneous group of registered nurses and certified nursing assistants also emerged. Strengthening guideline knowledge, coaching competencies and leadership is essential for sustainable, guideline-based reflection in practice.

Exposome project for health and occupational research night shift cohort (EPHOR-NIGHT): a unique resource to advance research on night shift work and chronic disease

Por: Harding · B. N. · Castano-Vinyals · G. · Broberg · K. · Albin · M. · Laurell · C. · Garde · A. H. · Nabe-Nielsen · K. · Fiehn · A. E. S. · van der Grinten · T. · Peters · S. · Vermeulen · R. C. H. · Gosh · M. · Loh · M. · Pronk · A. · Kogevinas · M. — Diciembre 5th 2025 at 09:25
Purpose

The EPHOR-NIGHT cohort was established to investigate how night shift work influences biological pathways and chronic disease risk using a comprehensive working-life exposome approach, focusing on cardiometabolic, mental health, cognitive and biological ageing outcomes.

Participant

The cohort includes 937 workers aged 20–65 years (88% female), primarily from the healthcare sector (96%) in Spain, Sweden, Denmark and the Netherlands. Participants were categorised as permanent day (39%), permanent night (35%) or rotating/other shift workers (26%). Data collection included questionnaires, daily ecological momentary assessments, wearable sensors tracking light, physical activity, heart rate and environmental exposures and biological samples (blood collected once and saliva collected during five points across the day), with harmonised protocols across countries.

Findings to date

From the 937 participants contributing data to the cohort, 708 had complete information from questionnaires, sensors and blood and saliva, with subsets undergoing advanced biological analyses, including genomics, targeted and genome-wide DNA methylation, telomere length and mtDNA copy number, metabolomics, transcriptomics, proteomics, hormone profiling and inflammatory biomarkers and blood metals. Many reported prevalent chronic conditions, including anxiety (27%), depression (18%) and metabolic disturbances. Night shift and rotating shift workers had greater exposure to long shifts and more scheduled rest days compared with day workers. Sleep duration and quality were poorest among permanent night shift workers.

Future plans

A 2-year follow-up was completed in June 2025, including the collection of additional biomarker data, psychosocial work environment data and data related to female sexual and reproductive health. Findings from the EPHOR-NIGHT study aim to inform prevention strategies and occupational health policies. Data will be made available to support broader research efforts on shift work and health.

Introduction

Neurodegenerative disorders (NDDs) represent an unprecedented public health burden. These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.

Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case–control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers.

Methods and analysis

People living with dementia, motor neuron disease, multiple sclerosis and Parkinson’s disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms.

Ethics and dissemination

Digital App for Speech and Health Monitoring Study was approved by the South Central—Hampshire B Ethics Committee (REC ref. 24/SC/0067), NHS Lothian (R&D ref. 2024/0034) and NHS Forth Valley (R&D ref. FV1494). Results of the study will be submitted for publication in peer-reviewed journals and conferences. Data from the study will be shared with other researchers and used to facilitate speech processing challenges for neurological disorders. Regular updates will be provided on the Anne Rowling Regenerative Neurology Clinic web page and social media platforms.

Introduction

Inguinal hernia repair is one of the most frequently performed operations in the paediatric population and can be performed according to two approaches: open or laparoscopic. At present, decisive evidence about the best treatment strategy is lacking and consequently, there is an ongoing debate about the most (cost-)effective treatment for the paediatric inguinal hernia. The aim of the Hernia Endoscopic oR opeN repair In chIldren Analysis—trial (HERNIIA2-trial) is to estimate the (cost-)effectiveness of the laparoscopic percutaneous internal ring suturing (PIRS) technique compared with open repair in children aged 0–16 years with a primary unilateral inguinal hernia.

Methods and analysis

A national multicentre randomised controlled trial will be performed including 464 children aged 0–16 years with a primary unilateral inguinal hernia. Patients will be randomised between the open or PIRS technique. The primary outcome is the number of reoperations within 2 years after primary surgery. Secondary outcome measures are: operative and postoperative complications, total duration of surgery, postoperative pain, length of admission, time to normal daily activities, cosmetic appearance of the scar, social and healthcare costs and health-related quality of life. Furthermore, cost-effectiveness will be assessed from a societal and healthcare perspective.

Ethics and dissemination

The protocol was approved by the ethics committee of the Amsterdam University Medical Hospital. Informed consent will be obtained by parents and, if possible, according to age, by patient. The study will be conducted according to the principles of the Declaration of Helsinki (2013) and in accordance with the Medical Research Involving Human Subjects Act (WMO) and Good Clinical Practice. Study findings will be disseminated through scientific publications, conferences and patient-friendly materials. The national study network of participating centres will facilitate rapid dissemination and implementation within the Netherlands and potentially abroad.

Predictability of perceptual factors of the intention-behaviour gap among young adults: a protocol for an explanatory mixed-methods study

Por: Bagherzadeh · B. · Sharma · M. · Hashemiparast · M. · Allahverdipour · H. — Diciembre 3rd 2025 at 17:58
Introduction

Behavioural intention is a strong predictor of actual behaviour; however, many health interventions fail among individuals with a high intention to adopt healthy behaviours. This discrepancy, known as the intention-behaviour gap, remains a critical challenge in health promotion. The purpose of this study is to present a protocol designed to explore the predictability of perceptual factors that hinder the conversion of intention into weight loss behaviour among young adults.

Methods and analysis

This study employs a sequential explanatory mixed-methods design, comprising two distinct phases. In the first phase, a quantitative cross-sectional survey with a descriptive-analytical approach will be conducted to assess the frequency of behavioural intention to lose weight and weight loss behaviours. A multistage cluster sampling method will recruit young individuals aged 18–29 years with a body mass index of ≥25 kg/m² in Malekan County, Iran. Data will be collected using a structured questionnaire that includes sociodemographic information, physical activity measurements, a dietary adherence questionnaire and items assessing subjective norms, attitudes, perceived behavioural control and behavioural intention based on the Theory of Planned Behaviour. In the second phase, a qualitative study will be conducted using a purposive sampling strategy to select participants who can provide insights into the quantitative findings. Data collection in this phase will primarily involve in-depth individual interviews. A grounded theory approach will be used to develop a comprehensive understanding of the factors that impede the conversion of intention into behaviour among young individuals.

Ethics and dissemination

This protocol has been approved by the Ethics Committee of Tabriz University of Medical Sciences (IR.TBZMED.REC.1403.646). Written informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed publications, conference presentations and reports to relevant health authorities.

Influence of the COVID-19 pandemic on drug and healthcare utilisation among First Nations with diabetes in Alberta, Canada: a retrospective cohort study

Por: Weaver · O. · Sarin · C. · Samanani · S. · Crowshoe · L. · Ye · M. · Eurich · D. T. — Diciembre 3rd 2025 at 17:58
Objectives

The purpose of this study was to assess changes in diabetes management and healthcare utilisation among First Nations with diabetes in Alberta before and during the COVID-19 pandemic.

Design

This analysis used a retrospective cohort in a case–control design. Individual-level administrative health datasets (1 April 2018 to 31 March 2022) were linked and data were formatted as a segmented interrupted time series.

Setting

This study took place in Alberta, Canada using administrative data.

Participants

Adult First Nations and non-First Nations (matched 1:1) with diabetes and living in Alberta were included (n=28 101; 53% female, 47% male).

Primary and secondary outcome measures

The primary outcome was the change in incidence rate of general practitioner (GP) visits, emergency department (ED) visits, hospitalisations and diabetes-related drug dispenses during-COVID-19 versus pre-COVID-19, quantified using generalised linear regressions. The secondary outcome was to report the reasons for non-drug outcomes pre-COVID-19 and during-COVID-19, based on primary diagnosis International Statistical Classification of Diseases and Related Health Problems codes.

Results

Pre-COVID-19, baseline rates of GP visits, ED visits, hospitalisations and drug dispenses were significantly higher among First Nations compared with non-First Nations (rate differences 398.32 (391.97–404.67), 100.58 (98.32–102.84), 14.49 (13.56–15.43), 876.98 (868.72–885.24) per 100 person-years (PY); p

Conclusions

Healthcare utilisation was substantially elevated among First Nations compared with non-First Nations peoples before and during COVID-19. While the generalisability of our findings to other health systems and populations may be limited, our findings are clinically applicable among First Nations across Alberta in order to help direct public health programming post-COVID-19.

Introduction

Cervical cancer (CaCx) is a leading cause of cancer-related deaths among women in South Africa, often presenting at advanced stages and requiring chemoradiotherapy. In South Africa, the burden is disproportionately high among women living with HIV, with limited access to radiotherapy further compounding treatment challenges. Despite this documented disparity, limited data exist on patients in a South African context. This protocol describes the research methodology to assess patterns of care, treatment delays, interruptions and survival outcomes in patients with advanced CaCx, addressing an urgent need for local data in low-income and middle-income countries to provide evidence-based improvements in care.

Methods and analysis

The Cervical Cancer Cohort at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH-CCC), initiated in 2023, is a mixed retrospective and prospective single-centre study investigating the characteristics, challenges and outcomes of patients with advanced CaCx. It includes women aged ≥18 years with a histopathological diagnosis of stage IB3–IVA CaCx treated at CMJAH Radiation Oncology. The retrospective component covers data from September 2018 to August 2023. Data collection is complete and the team is currently conducting quality control. The prospective component began in October 2023 and aims to enrol participants over 2 years, with follow-up for up to 3 years. The study is ongoing, and an extension for continued enrolment beyond September 2025 is being sought. Participants provide baseline data on demographics, socioeconomic status, cultural influences and healthcare access, with updates every 3 months. When necessary, the next of kin provides follow-up information. The study aims to inform strategies to improve outcomes and reduce the CaCx burden in South Africa.

Ethics and dissemination

Ethics approval for this study was obtained from the Human Research Ethics Committee (Medical) at the University of the Witwatersrand in Johannesburg, South Africa, with an ethical clearance certificate (MM221001 MED22-09-085). The results will be widely distributed through presentations at national and international conferences and published in peer-reviewed open-access journals, ensuring wide access to the results.

Differential contribution of α2δ auxiliary subunits of voltage-gated calcium channels in mouse models of pain and itch

Voltage-gated calcium channels (VGCCs) are multimeric proteins composed of alpha 1, β and γ subunits, as well as one of four auxiliary α2δ subunits. Although there is considerable preclinical and clinical evidence for a contribution of VGCCs to nociceptive processing, notably the gabapentin-targeted α2δ-1 subunit, unclear is the extent to which other α2δ subunits contribute to baseline or injury-altered pain and itch processing. Here, we investigated the anatomical and behavioral consequences of deleting α2δ-2, α2δ-3 or α2δ-4 in the mouse and report that selectively ablating each α2δ subunit leads to different, and in some cases, opposite effects on behavioral indices of pain and itch. Specifically, deleting α2δ2 resulted in mechanical and heat hypersensitivity, and an increase in spinal cord microglial immunoreactivity, but reduced scratching (presumptive) itch in response to a pruritogen. In contrast, ablation of α2δ3 led to thermal hyposensitivity, but no change in mechanical responsiveness or indices of itch. Mice deficient for α2δ4 exhibited hyposensitivity across pain modalities and only minor itch deficits. Interestingly, these differential effects were limited to baseline nociceptive responses, therefore we conclude that the α2δ-2, α2δ-3 and α2δ-4 subunits of VGCCs differentially contribute to pain and itch processing. The mechanisms underlying these differences remain however to be determined.

The Associations Between Nurses' Perceived Adequacy of Staffing and Quality of Nursing Care and Job Enjoyment: A Multilevel Modelling Approach

ABSTRACT

Aim

To explore the associations of (1) shift-to-shift Nurse Perceived Adequacy of Staffing Scale (NPASS) scores and (2) the relative contribution of individual NPASS items to nurse-perceived quality of care (NPQoC) and job enjoyment.

Design

Multihospital prospective observational study.

Methods

The study was conducted across 15 medical, surgical or acute admission hospital wards in three teaching hospitals in the Netherlands. Vocationally and bachelor-trained nurses conducted 1550 measurements of perceived adequacy of staffing using the NPASS, NPQoC and job enjoyment in 797 shifts. Multilevel models were used to assess associations between NPASS scores and NPASS items and the outcome variables.

Results

Higher NPASS scores were significantly associated with improved NPQoC and job enjoyment. An increase in 1.0 point NPASS score leads to an increase of 0.97 points in NPQoC and 1.04 points in job enjoyment. Of the NPASS items, energy level, adherence to protocols and the opportunity for adequate breaks had the most positive effect on both outcomes.

Conclusion

Perceived adequacy of staffing as measured by the NPASS is highly relevant for improvements in both NPQoC and job enjoyment.

Implications for the Profession and/or Patient Care

Decision-makers on nurse staffing should incorporate the NPASS in staffing methods to ensure adequate staffing and the associated benefits. Policies that ensure adequate breaks, adherence to protocols and maintenance of nurses' energy levels during the shift should be implemented with special attention.

Impact

This study provides supportive evidence for incorporating nurses' perceived adequacy of staffing, as measured by the NPASS, to ensure adequate staffing. This is crucial for nurse retention, and therefore vital to maintaining accessible healthcare given the global nursing shortages.

Reporting Method

The STROBE checklist was used to conduct and describe the study.

Patient or Public Contribution

This study did not include patient or public involvement in its design, conduct or reporting.

Development of a low-cost culture medium from industrial and environmental by-products for sustainable cultivation of Lactic Acid Bacteria

by Michele Letitia Tchabou Tientcheu, Pierre Marie Kaktcham, Edith Marius Foko Kouam, Laverdure Tchamani Piame, Lysette Chabrone Djodjeu Kamega, Aarzoo , Agnihotri Shekhar, Singh Bhim Pratap, François Zambou Ngoufack

Conventional culture media such as de Man, Rogosa and Sharpe are essential for the growth of lactic acid bacteria and the production of metabolites used in the food and pharmaceutical industries. However, their high cost limits their application, particularly in low and middle-income countries. This study aimed to develop a cost-effective and efficient culture medium based on agro-industrial and environmental by-products, pineapple peels, sugarcane molasses, and black soldier fly larvae cake. After physico-chemical analysis of the by-products, excluding sugarcane molasses, a statistical mixture design was used to determine the optimal proportions for supporting lactic acid bacteria growth and bacteriocin production. Growth and metabolite production were monitored via plate count and agar well diffusion assays respectively. The strains tested belonged to the genera Lactobacillus, Bifidobacterium, Streptococcus, Lactococcus, and Bacillus as an out taxa group. The larvae cake showed high protein (48.47 ± 0.14%) and amino acid (17 types) content, while pineapple peels and molasses were rich in carbohydrates (89.52 ± 0.16% and 86.86 ± 0.07%). Based on regression models, the compromise formulation was defined as 55.15% larvae cake hydrolysate, 19.85% pineapple peel hydrolysate, and 25.00% sugarcane molasses. This medium highly supported lactic acid bacteria growth (9.43–9.86 log CFU/mL) compared to MRS and M17 (9.20–9.69 log CFU/mL), with Lactobacillus strains performing better. It also supported bacteriocin activity (11.0–14.5 mm inhibition zones), higher or similar to MRS and M17, with Lactococcus lactis subsp. lactis MA2 exhibiting the strongest effect. These results highlight the potential of this formulation as a sustainable, low-cost alternative for microbiology and biotechnology, particularly in resource-limited settings. The determination of its formula will allow its manufacture once the proximate compositions of the ingredients are known, regardless their origin. Future investigations will focus on optimisation of culture conditions, powder form formulation, and cost evaluation.
