Theory-based physical activity (PA) interventions improve moderate to vigorous physical activity (MVPA) among breast cancer survivors, yet limited research has examined when psychosocial changes occur during intervention delivery. Understanding temporal changes in theoretical constructs during PA adoption may enhance intervention delivery and outcomes. The purpose of this study is to examine longitudinal changes in self-efficacy, self-regulation and affect (intrapersonal constructs from Social Cognitive Theory) and social support (interpersonal construct) during a 12-week theory-based PA program (webMFT) and their association with participants' active minutes (measured by Fitbit) over 12 weeks and intervention engagement (receipt of 12 weekly peer coaching calls).

In a randomized controlled trial with 61 participants, 30 were randomized to receive webMFT (mean age = 58.1 [SD = 8.55], 1.40 years post-diagnosis [SD = 0.5], 80% Stage 0-1 cancer, 80% White) delivered by 10 peer coaches. Only the webMFT participants were assessed; the comparison group (MVPA Tracking) was not included in the analyses. webMFT participants received a Fitbit tracker and weekly PA coaching calls tailored to Fitbit PA data. At baseline, 4, 8 and 12 weeks, they completed questionnaires assessing multidimensional self-efficacy (task, coping, scheduling), self-regulation skills, affective response and social support for PA. Mixed effects regression models examined changes in constructs and their association with Fitbit active minutes/week and intervention engagement.

Increases in total self-efficacy, scheduling self-efficacy, positive affect and social support from family and friends were significantly associated with participants' PA over 12 weeks. There were no significant associations between changes in self-regulation skills, task or coping self-efficacy with PA. Improvements in total self-efficacy, scheduling self-efficacy, self-regulation, affective response and family social support were positively associated with intervention engagement.

Participants' self-efficacy, specifically, for scheduling PA, positive affect and social support for PA adoption and intervention engagement merit future examination.

Following the publication of the above article, a concerned author drew to the authors' attention that, regarding the cell migration assay experiments shown in Fig. 4 on p. 1099, Fig. 4B and C, showing the results of the 'NC' and 'Mock' experiments, contained an overlapping section of data, suggesting that these data panels were derived from the same original source where different experiments were intended to have been portrayed.  The authors have been contacted by the Editorial Office to offer an explanation for this apparent anomaly in the presentation of the data in this paper, and we are awaiting their response. Owing to the fact that the Editorial Office has been made aware of this potential issue concerning the scientific integrity of this paper, we are issuing an Expression of Concern to notify readers of this potential problem while the Editorial Office continues to investigate this matter further.

This article summarizes the top 20 research studies of 2025 identified as POEMs (patient-oriented evidence that matters). Treating male sex partners of female patients with oral and topical medication reduces recurrence of bacterial vaginosis. Anti-influenza drugs do not reduce hospitalizations or mortality. COVID-19 vaccines still improve mortality and reduce hospitalizations. Influenza vaccines are safe in pregnancy. Vaginal estrogen appears to be safe in breast cancer survivors. Women with normal bone density given zoledronic acid every 5 years have fewer fractures. Early post-partum insertion of a long-acting reversible contraceptive is associated with fewer pregnancies vs delayed insertion. Early medication abortion before pregnancy confirmation is safe and effective. After stent placement in patients with atherosclerotic coronary vascular disease who are taking an anticoagulant, adding aspirin worsens outcomes. After catheter ablation for atrial fibrillation, discontinuing anticoagulants after 1 year is safe if atrial arrhythmia does not recur, whereas left atrial appendage closure is superior to oral anticoagulation. For patients with provoked venous thromboembolism and at least one ongoing risk factor, 12 months of apixaban is better than 3 months. Clopidogrel is slightly more effective than aspirin for the secondary prevention of myocardial infarction and stroke over 3 years. Intensive blood pressure lowering decreases cardiovascular events but increases rates of hypotension and syncope, and there are concerns about the applicability of the data to the United States. Duloxetine, milnacipran, and pregabalin provide meaningful pain reduction in adults with fibromyalgia. Amyloid-directed monoclonal antibodies do not provide clinically meaningful cognitive benefits and may cause harms. Bright light therapy is effective for nonseasonal depression. Water exposure 6 hours after cutaneous surgery does not increase the risk of complications. A meta-analysis of platelet-rich plasma injections for knee osteoarthritis concluded that high-quality studies found no meaningful pain improvement. Using an oral challenge to rule out sulfonamide allergy is safe when used with a risk assessment tool.

Data on the clinical significance of viral-bacterial co-detection by molecular methods in adults is limited. We aimed to determine how often respiratory viruses and bacteria are co-detected in acutely ill adults and whether co-detection is associated with worse clinical outcomes than detection of a virus or bacterium alone.

We prospectively enrolled 998 adult patients presenting to the emergency department with symptoms of respiratory infection, fever, chest pain, or poor general condition. Nasal swab samples were taken at entry and analysed by multiplex PCR for 16 respiratory viruses. PCR for 7 bacterial pathogens was performed later on 912 frozen-thawed samples. Medical records were reviewed for the clinical outcomes. Analysis of variance (ANOVA) was used to compare the differences in CRP and age between detection groups. The risk of major outcomes was evaluated using multivariate logistic regression.

Both viral and bacterial PCR were positive in 36 of 912 patients (4%). The most common virus in the Co-detection group was rhinovirus (21/36, 58%) and the most common bacterium Streptococcus pneumoniae (20/36, 56%). The patients in the Co-detection group were younger than those in the Sole bacteria group, who in turn were younger than those in the Sole virus group. Relative to the Negative group, the risk of pneumonia was highest in the Sole bacteria group (aOR 3.53, p < 0.01) and lower, though still elevated, in the Co-detection group (aOR 2.36, p = 0.03). The risk for antibiotic treatment during 30-day follow-up was greatest in the Co-detection group (aOR 4.42), followed by the Sole bacteria (aOR 2.40) and Sole virus (aOR 2.15) groups (all p < 0.01). There was no significant difference between the groups in the risk of death or ICU care.

Viral and bacterial co-detection was rare in acutely ill adults. Although co-detection was associated with the highest risk of antibiotic treatment, it did not carry the highest risk of pneumonia and was not associated with death or ICU admission. Routine use of multiplex PCR for detecting respiratory viral and bacterial pathogens is therefore unlikely to add clinical value in this population. Larger cohorts powered for severe outcomes and real-time result reporting, are needed to determine whether respiratory viral bacterial testing can meaningfully guide clinical management.

Evidence linking exposure to airborne particulate and gaseous pollutants, as well as mold spores, with asthma control and severity is well established. A growing body of literature has demonstrated that ventilation and air filtration can improve indoor air quality (IAQ); however, clinical evidence on their comparative health impacts remains limited. Therefore, this trial aims to evaluate the long-term effectiveness of energy recovery ventilators (ERVs) and portable air cleaners (PACs) in reducing indoor air pollutants and mold levels and improving health outcomes in individuals with asthma. Secondary objectives includes associations between housing conditions, occupant behaviors, indoor environmental exposures, and asthma-related health outcomes.

The AIRVAC study is a single-blind, placebo-controlled, 4-arm, parallel-group, randomized controlled trial, with a pre-intervention period of up to 1 year and a 1-year post-intervention period. Children aged 5-17 years and adults with physician-diagnosed asthma will be recruited from more than 80 households across the Dallas-Fort Worth (DFW) area in Texas. Following the pre-intervention period, each household will be randomized to receive one of four different interventions midway through the study: (1) active ERVs, (2) sham ERVs, (3) active PACs, and (4) sham PACs. Primary health outcomes include asthma control; secondary outcomes include pulmonary function, asthma-related quality of life, stress, and sleep quality. Initial housing assessments will be conducted prior to the pre-intervention period to characterize occupant behaviors and housing-related factors that may contribute to asthma exacerbations and affect ERV installation. Environmental exposures will be assessed by combining measurements of indoor and outdoor air pollutants, including particulate matter (PM), nitrogen dioxide (NO2), carbon monoxide (CO), and volatile organic compounds (VOCs), as well as temperature, relative humidity, and indoor and outdoor mold, using low-cost and research-grade air quality sensors and mold sampling methods.

Findings from the AIRVAC study will provide important evidence on the comparative effects of residential ventilation and air cleaning interventions on IAQ, mold, and asthma-related health outcomes among children and adults with asthma. The study will also examine the relationships among housing characteristics, occupant behaviors, indoor environmental exposures, and asthma-related health outcomes, while providing insights into the operation and performance of residential ventilation and air cleaning interventions in vulnerable households.

Pandemics threaten economies, security, and public health, requiring strong global and local collaboration and coordination. Public receptivity to emergent vaccine technologies is essential to pandemic readiness. Although messenger RNA (mRNA) vaccines offer rapid adaptability and hold promise, their use during the COVID-19 pandemic was met with polarizing debates that raise questions about the conditions needed to support acceptable and equitable use of new vaccines.

This deliberative dialogue study aims to generate consensus on how to ensure informed, accessible public engagement and strengthen public trust in a climate of divisiveness and misinformation, disinformation, and malinformation. Using mRNA vaccines as a case study, the project's specific research objective is to seek insights into what people believe is needed for public understanding, equitable access, and acceptance of emerging vaccine technologies.

Using a sequential deliberative dialogue design, this study invites individuals with significant influence on pandemic readiness and those most likely to be disproportionately affected by related decisions into reflective, conversational, workshop-style online events and self-led dialogues. Dialogues and guiding questions are informed by a knowledge synthesis on what is unknown about mRNA vaccine public sentiments based on a rapid review, an environmental scan, consultations with experts across sectors, and ongoing updates from the dialogues. Data will be analyzed in situ in an iterative and collaborative synthesis of general agreements between dialogue contributors in response to guiding questions and emerging themes. Dialogue reports will be drafted by the research team based on observational notes, transcripts, and video recordings and reviewed by contributors. In summative dialogues, the research team will present main threads of dialogue, responding to research objectives and newly identified knowledge gaps and collecting input to inform dialogue outputs.

This study was funded in May 2025. As of June 2026, we have conducted 10 deliberative dialogues and supported 1 self-led dialogue, engaging 77 contributors across sectors and disciplines. We held 2 summative dialogues with 18 attendees, where we presented the main threads of dialogue as identified by the research team through collaborative analysis. We have started incorporating input from closing dialogues into the final reports and expect to publish the results in the second half of 2026, both as lay-language reports and peer-reviewed manuscripts.

This protocol outlines a consensus-building process capable of deepening the understanding of vaccine hesitancy and strengthening pandemic readiness and public trust in Canada. Dialogues are expected to provide general agreements on how to enhance science and health literacy, tailor communications considering historical inequities, respond to the needs of health care workers, and navigate polarization around vaccination. By creating space for shared learning and collective insight, this study supports the rebuilding of trust in public health institutions as they adapt to evolving societal expectations.

Gaps in knowledge, inhalation skills, and adherence continue to hinder effective chronic obstructive pulmonary disease (COPD) management.

The study was conducted to describe the status of COPD-related knowledge, practical skills for inhalation and breathing exercises, and treatment adherence among patients with COPD and to identify the relationships between these variables.

A cross-sectional study was conducted among 420 outpatients with COPD. Data were collected in 2 rounds, including interviews to assess patients' knowledge and treatment adherence and checklist-based observations of patients' practical skills. Multivariable logistic regression analysis was used to evaluate the associations between knowledge and practical skills and the status of treatment adherence.

A total of 420 outpatients with COPD were included; 331 (78.8%) participants had inadequate COPD-related knowledge, 268 (63.8%) demonstrated adequate practical skills, and 155 (36.9%) achieved overall treatment adherence. In multivariable logistic regression, higher knowledge scores were associated with better treatment adherence (adjusted odds ratio [aOR] 1.20, 95% CI 1.06-1.31; P=.001). Participants who correctly performed inhaler-use techniques were more likely to be adherent than those with incorrect technique (aOR 3.10, 95% CI 2.10-4.70; P=.001). Likewise, adequate breathing-exercise skills were associated with higher adherence (aOR 1.70, 95% CI 1.08-2.71; P=.02).

Higher COPD-related knowledge and better practical skills in inhaler use and breathing exercises were associated with better treatment adherence among outpatients with COPD. Because of the cross-sectional design, these findings indicate associations rather than causal relationships. These observed associations may help inform future intervention studies evaluating patient education and skill-based training, although their effectiveness should be confirmed in longitudinal or interventional studies.

Health system resilience is often described through the World Health Organization building blocks, yet in protracted crises it depends on whether governance, financing, workforce, information systems, service delivery, and accountability can convert crisis response into institutional reform.

This study examines how far Yemen's health system responses to prolonged conflict, economic decline, disease outbreaks, and COVID-19 progressed beyond absorptive and adaptive resilience toward transformative resilience, and how strategic health policy across the building blocks shaped this transition.

We conducted 30 in-depth interviews with national and subnational policymakers and health leaders in Yemen between May and July 2025. Data were analysed in ATLAS.ti 25 using framework-informed thematic analysis that combined a priori categories from the World Health Organization health system building blocks and resilience capacities with inductively developed empirical codes.

Yemen demonstrated externally buffered absorptive capacity sufficient to prevent complete system collapse, together with uneven and localised adaptation through crisis committees, donor-supported financing, temporary workforce mobilisation, intensified surveillance, oxygen and isolation capacity, and referral workarounds. However, these responses were largely reactive, donor-dependent, and unevenly institutionalised. Transformative resilience remained constrained by fragmented authority, under-protected recurrent financing, workforce instability, weak data-to-decision pathways, limited referral governance, and the absence of formal learning-to-reform mechanisms.

Yemen's experience shows that resilience in protracted crisis settings should be judged not only by the survival of repeated shocks, but by whether absorptive and adaptive gains are converted into institutional capability through strategic policy alignment across the health system.

To map the existing evidence on the impact of transverse craniofacial alterations on mandibular advancement device treatment outcomes in adults with obstructive sleep apnea, with the objective of identifying knowledge gaps and informing future research and clinical decision-making.

A systematic literature search was conducted in six databases. Additionally, gray literature sources were searched, and clinical trial registries, including ClinicalTrials.gov, were screened for RCT protocols. The reference lists of all included sources of evidence were also screened, and experts in the field were consulted.

The literature search yielded a total of 1,508 references after duplicate removal. Nine studies and one conference report were found eligible for inclusion. The literature demonstrated heterogeneous associations between transverse craniofacial characteristics and mandibular advancement device treatment outcomes. Most studies (n = 7) did not identify significant associations between isolated transverse craniofacial measurements and treatment response. Greater mandibular transverse dimensions were associated with better therapeutic outcomes in two studies, whereas one study reported better treatment response in individuals with smaller mandibular transverse dimensions. Reduced maxillary width and unfavorable anatomical balance were more frequently associated with greater obstructive sleep apnea severity or poorer treatment outcomes.

While some studies suggest that the response to mandibular advancement devices in obstructive sleep apnea is associated with transverse mandibular dimensions, most investigations have not identified this relationship. Future standardized and well-designed studies are needed to clarify the influence of this anatomical characteristic on the outcomes of this common treatment for obstructive sleep apnea.

In a household cohort enrolled during the COVID-19 pandemic in Lima, Peru, detections of human rhinovirus, endemic coronaviruses, and parainfluenza viruses were significantly lower compared to these viral detections in a similar household cohort followed during the same seven epidemiological weeks in a period immediately preceding the COVID-19 pandemic.
