Knee osteoarthritis (OA) causes pain, reduced function and disability and may require total knee replacement (TKR). Although TKR is effective, up to 20% of patients remain dissatisfied, partly due to poor preoperative function and unrealistic expectations. Long waiting times for surgery may worsen patients’ function, yet preoperative physiotherapy is rarely offered. Prehabilitation—exercise and education before surgery—could improve postoperative recovery, but current evidence is limited. This trial investigates whether adding prehabilitation to standard care before TKR improves postoperative patient-reported joint awareness, enablement and knee function.

This multicentre, randomised controlled parallel-group trial is planned to be conducted within two specialised orthopaedic outpatient rehabilitation units in the southeast healthcare region of Sweden. Eligible patients (40–85 years, awaiting unilateral TKR) are randomised 1:1, stratified by age (≤67, >67 years), to either 8 weeks of prehabilitation—comprising two times per week supervised exercise therapy (strength, range of motion and balance) and education—in addition to standard care, or to standard care alone. Standard care consists of self-care, a single standardised preoperative education session and standardised postoperative rehabilitation. Assessments are conducted at baseline, post-intervention, 1 week pre-surgery and 6, 12 and 52 weeks post-surgery. A total of 110 patients will be recruited to the trial. Primary outcomes are joint awareness (Forgotten Joint Score-12) and patient enablement (modified Patient Enablement Instrument-2). Secondary outcomes are patient satisfaction (5-category Likert scale), the Knee injury and Osteoarthritis Outcome Score, the EuroQol 5 Dimension 3 Level questionnaire, the International Physical Activity Questionnaire—short form, objective function and accelerometer-based physical activity. Analyses will follow intention-to-treat and per-protocol principles. Between-group and within-group differences will be tested using t-tests or non-parametric equivalents, and linear mixed models or generalised linear models. Multiple linear regression and logistic regression will be used to analyse predictor variables for the primary outcomes. Sensitivity analyses will be performed to quantify the magnitude of missing data from patients lost to follow-up.

The trial has received ethical approval from the Swedish Ethical Review Authority (reg. no.2023-05120-01) and complies with the Declaration of Helsinki. Signed informed consent is collected for all patients before entering the trial. Results will be submitted for publication in a peer-reviewed journal and presented at international/national conferences. The findings may improve future clinical guidelines and care pathways for patients undergoing TKR.

NCT06290336.

To determine if communication disorders (1) increase the risk for common mental and physical health conditions and (2) if risk varies by age of onset (≤25 years (developmental) or >25 years (acquired)) by using the large-scale All of Us Research Program participant-reported survey data to electronic health records (EHR) data. We hypothesised that adults with a communication disorder would have a higher risk of mental and physical health conditions.

A retrospective cross-sectional study.

Secondary analysis of EHR and online surveys conducted in the USA.

We assessed 410 360 US adults enrolled in the All of Us Research Program from August 2023 to May 2024 for study eligibility. We used medical diagnosis of a communication disorder from EHR data to group participants into communication disorder (CD) and typical communication (TC) groups, and age of first diagnosis to assign to age of onset (≤25 years (developmental) or >25 years (acquired)) groups. 234 519 participants (median (IQR) age 57.00 (41.00, 68.00); 3700 (1.6%) qualified for the CD group) were included in the analyses.

Primary outcome measures were diagnosis of 11 common mental and physical health conditions from EHR data.

Multiple logistic regression models with propensity score weighting revealed that participants with CD had higher odds for attention deficit hyperactivity disorder, anxiety, asthma, cancer, chronic kidney disease, cardiovascular disease, depression, diabetes and hypertension. Estimates for chronic kidney disease (acquired: adjusted OR (AOR), 1.89 (1.62, 2.20); developmental: AOR, 1.26 (0.42, 3.82)), diabetes (acquired: AOR, 1.64 (1.49, 1.81); developmental: AOR, 1.51 (0.95, 2.41)), hypertension (acquired: AOR, 2.02 (1.85, 2.19); developmental: AOR, 1.16 (0.80, 1.68)) and substance use (acquired: AOR, 1.76 (1.47, 2.12); developmental: AOR, 1.08 (0.65, 1.82)) varied by age of onset. Confounding factors are controlled in the analysis, such as age, income, employment, enrolment, sex at birth, gender identity and US census division.

Our study demonstrates that adults with CD experience health disparities compared with adults with TC, and that these disparities vary by age of onset of CD.

Malaria remains a major public health challenge in India, with transmission dynamics varying widely across ecological, epidemiological, sociobehavioural and health system contexts. Achieving the national malaria elimination target by 2030 requires integrated, context-specific evidence to design effective interventions. This study aims to generate a comprehensive understanding of malaria transmission and factors surrounding it across diverse eco-epidemiological settings in India by assessing malaria burden, identifying determinants of transmission, evaluating health system performance and equity, characterising vector bionomics and insecticide resistance, and examining the influence of environmental drivers.

This longitudinal, multicentric study will be conducted in collaboration with the national programme in 12 districts spanning 10 states in India, covering a population of around 25 000 individuals representing varied ecological contexts (urban, periurban, rural, forest-foothill and coastal) and malaria endemicity levels. In each district, two clusters (villages) with a population of 1000 individuals will be included. A baseline mass survey will estimate malaria prevalence using bivalent rapid diagnostic tests (RDTs) and blood smear microscopy, with low-density parasitaemia detected by PCR in a subset of RDT-negative samples. Participants will be followed for 1 year, with monthly screening of symptomatic individuals using RDT and microscopy, and testing a subset of asymptomatic individuals to detect subclinical infections. Sociobehavioural data will be collected through structured interviews and household observations, with purposive inclusion of vulnerable groups, pregnant women, migrants, elderly persons, individuals with disabilities and tribal populations to assess equity dimensions through mixed-methods approaches. Health system performance will be evaluated through key informant interviews with programme officials, health workers, patients, private practitioners and traditional healers. Entomological surveillance will document vector species composition, density, infection rates and assessment of susceptibility status and intensity of insecticide resistance to commonly used public health insecticides. Environmental variables, including temperature, rainfall and humidity, will be linked with entomological and epidemiological data to explore spatiotemporal relationships.

The protocol was approved by the Institute Human Ethics Committee of ICMR-Vector Control Research Centre (IHEC 03-0125/N/F). All standard ethical practices will be adhered to. The findings will be shared with stakeholders and published in reputed open-access journals.

The literature examining direct-to-consumer (DTC) commercial virtual care has expanded rapidly over the past decade. Our objective was to synthesise the nature and range of evidence on DTC commercial virtual care.

Scoping review.

MEDLINE ALL, EMBASE Classic+Embase, CINAHL, HealthSTAR, PsycINFO, CENTRAL and grey literature sources.

We included original research studies published in English or French between 1 January 2016 and 30 April 2025 that assessed DTC commercial virtual care in all contexts and in all populations.

Screening titles and abstracts, and full-text manuscripts, and extracting data was done in duplicate. We analysed quantitative data using descriptive statistics and reported findings in tables. We provided a narrative summary of textual data.

After excluding duplicates, we identified 8055 studies for title and abstract screening; 691 articles for full-text screening; and 103 studies meeting our inclusion criteria. 32 studies (31.1%) reported financial ties to the virtual care industry. 67 (65.0%) studies were conducted in the USA. Studies were largely quantitative (87/103 (84.5%)) or mixed methods (8/103 (7.8%)) studies and used cross-sectional (85/95 (89.5%)) designs. Most quantitative studies were descriptive, reporting on quality of care, health outcomes, platform characteristics and patient views, with only 24 of the 95 quantitative studies (25.3%) including a control or comparison group. 18 of these 24 studies (75.0%) compared the quality of care, costs and/or utilisation to other models of care and reported variable findings. The rest compared patient characteristics. Few studies assessed clinician perspectives or addressed privacy-related ethical concerns.

Despite a large number of studies assessing DTC commercial virtual care, we have little insight into impacts on quality of care, health outcomes, health system utilisation and privacy-related ethical concerns. The financial ties with industry suggest that there may be bias in the body of research literature.

Socioeconomic inequalities significantly impact access to healthcare services for individuals with type 2 diabetes mellitus (T2DM). This study investigates these inequalities in Iran, focusing on factors such as asset, sex, urban–rural residence, age, education, employment status, and marital status.

Cross-sectional study.

This study used data from the national ‘Diabetes Care (DiaCare)’ study, a population-based survey conducted from 2018 to 2020 in Iran.

Socioeconomic status (SES) was assessed using Principal Component Analysis (PCA) based on assets. Socioeconomic inequalities in access to physicians, pharmacies and laboratories were measured using the Concentration Index (CI) and Erreygers Corrected Concentration Index (ECI). Decomposition analysis was performed using a probit regression model to assess the contributions of various factors to the observed inequalities.

Among 13 315 patients with T2DM, 5.8% lacked access to physicians, 6.8% to pharmacies and 8.7% to laboratories. The CI was positive and statistically significant for access to physicians (0.0614), pharmacies (0.0787) and laboratories (0.0875), indicating better access concentrated among higher SES individuals. Urban residents had the largest positive marginal effects on access to physicians (0.032), pharmacies (0.078) and laboratories (0.053), with percentage contributions of 13.21%, 23.23% and 17.39%, respectively. Higher asset quintiles showed substantial contributions to inequalities, with the highest quintile contributing 10.5% to physician access inequality, 9.68% to pharmacy access and 9.16% to laboratory access. Education level also positively impacted access, with high school education contributing 0.64% and college education 0.52% to access inequalities. Sex differences showed a negative marginal effect for women, indicating slightly lower access.

Socioeconomic factors, particularly asset, residence and education, significantly impact access to healthcare services for patients with T2DM in Iran. Policies should focus on reducing barriers to healthcare access, especially for lower SES and rural populations.

The Happy Healthy Active Children (HHAC) initiative is a multicomponent community-based initiative aimed at promoting physical activity, food literacy and nature literacy among children in early childhood kindergarten and primary school settings. Developed in collaboration between Activity Experts and Community Stakeholders, HHAC integrates thematic activities (Play, Nature, Food) across kindergartens, schools and the broader community. The initiative responds to growing concerns about declining physical activity levels, insufficient contact with nature and poor dietary habits in childhood, factors known to influence long-term health and well-being. This protocol outlines the design, implementation and planned evaluation of the HHAC initiative.

HHAC is carried out within the long-term strategic initiative Tingbjerg Changing Diabetes. Following the Supersetting approach, HHAC addresses inequity in health by mobilising resources across local settings (kindergartens, schools and the local community arenas) and population groups (children, parents, staff and other community members) to develop and implement contextually relevant activities promoting outdoor play, cooking and nature experiences. Activities are evaluated using a within-subject design in kindergartens, while in schools a quasi-experimental design with matched control groups is applied. Data is collected at baseline and follow-up through accelerometry, validated questionnaires and structured observations. Primary outcomes include physical activity levels, food literacy and nature literacy. Analyses apply linear mixed-effects models to account for repeated measures and clustering at the institutional level. The evaluation also investigates implementation processes and context-mechanism configurations through a comprehensive realist evaluation. This includes developing a programme theory, conducting interviews with children, parents, staff and other local stakeholders and participant observations aiming to explore experiences and the mechanisms through which the activities contribute to changes in behaviour and well-being. All data will be analysed and condensed for a model for transferability.

Findings will be disseminated through peer-reviewed journals, conference presentations and public engagement activities targeting educators, policymakers and health professionals. The intervention materials will also be made freely available to support broader implementation. The study procedures were registered and approved by The Capital Region’s centre for data reviews ‘Videnscenter for Dataanmeldelser’ (Reference: P-2023–14277). All procedures were carried out under relevant regulations and guidelines. Written information about the study was given to all school principals, teachers and parents/guardians before the start of the study, and written informed consent is obtained from all legal guardians of all participants in their native language prior to child enrolment.

To detail the development of the Canadian National Questionnaire on Overdose Monitoring (CNQOM), a questionnaire aimed at assessing the perspectives of key stakeholders towards elements of overdose prevention interventions—supervised consumption sites (SCSs) and overdose hotlines and applications (ORHAs).

Cross-sectional survey.

Canadian health system.

English or French speaking adults from four key informant groups: people who use substances (PWUS), health professionals, emergency responders and the general public.

Test–retest reliability of CNQOM items.

A novel questionnaire was developed. Item development followed a standard approach, with face validity verified by representatives from the four informant groups. Input from experts in harm reduction and addiction medicine enhanced content and face validity of the questionnaire. A rigorous response validation approach was undertaken to ensure respondents were human and from Canada. Test–retest reliability items were assessed using Spearman’s rank correlation, Wilcoxon rank-sum test and Cohen’s kappa.

After data cleaning and response validation, 4445 valid responses were obtained from the four key informant groups. Respondents represented a range of sociodemographic backgrounds and housing scenarios from all provinces and territories in Canada. Test–retest reliability was assessed using a small subsample of 142 participants (primarily from general public informants). Questionnaire items demonstrated slight to substantial stability in responses (kappa coefficients: 0.15–0.58; Spearman’s r: 0.08–0.66).

The CNQOM is the first online questionnaire in Canada designed to capture perspectives and attitudes towards specific elements of SCSs and ORHAs among diverse key informant groups. Our questionnaire was administered to a large, geographically diverse sample and designed to capture the perspectives of four key informant groups. Lower than expected test–retest reliability may be explained by lack of participant familiarity with SCS and especially ORHAs and the impersonal nature of the instrument content among some respondents. Future work will elucidate key informant perspectives on these services based on the data.

The functional resonance analysis method (FRAM) is increasingly used to analyse healthcare processes. FRAM uses four steps to analyse a process and its potential variability. We systematically reviewed studies using FRAM in healthcare on how the four steps in FRAM are reported, defined and supported by data.

Systematic review following the preferred reporting items for systematic reviews and meta-analyses 2020 guidelines.

Web of Science, PubMed, Embase, Scopus, PsycINFO, Dimensions and Lens were searched up to December 2025.

All peer-reviewed studies using FRAM in a healthcare context that presented a FRAM visualisation were included. The papers had to be written in English.

Two independent reviewers screened titles and abstracts, and subsequently the full text of selected papers. Data was extracted reporting on the steps of FRAM, how functions were supported by data, and the functions and couplings of the visualisations.

Sixty-eight papers were included, of which 20 (29%) reported at least one aspect of all four steps in FRAM. While most studies (85%) described how functions were supported by data, the methods used varied widely. Terminology was interpreted differently concerning variability, the output of variability and the effect of combined variability.

Most FRAM studies in healthcare do not report all steps of FRAM, and interpretations of key terms differ. FRAM studies should more clearly describe which steps of the method are conducted, and how data is collected and analysed. Refinement of FRAM guidelines, particularly on data use and terminology, would enhance consistency and comparability across studies.
