Smoking cessation is a pressing public health concern. Behavioral therapy has been widely promoted as a means to aid smoking cessation. Acceptance and commitment therapy (ACT), based on the principles of cognitive behavioral therapy, can help participants accept, rather than suppress, the physical and emotional experiences and thoughts associated with not smoking, identify experiential avoidance behaviors, strengthen the determination to quit, and ultimately commit to adaptive behavioral changes guided by smoking-cessation-related values, thereby achieving the goal of quitting smoking.
To assess the effects of ACT compared with other smoking cessation interventions by examining three key outcomes: cessation rates, smoking behaviors, and psychological outcomes.
We searched 8 databases and 2 registration platforms, covering the period from inception to March 26, 2025. We included only randomized controlled trials that recruited adult smokers and implemented ACT for smoking cessation, with the comparison group receiving either active treatment, no treatment, or any other intervention.
A total of 23 studies involving 8951 participants were included. The findings indicated that, compared with all types of control interventions, ACT significantly increased smoking cessation rates both immediately postintervention (RR = 1.48, 95% CI [1.03, 2.14], p = 0.04, I 2 = 81%) and at short-term follow-up (RR = 1.63, 95% CI = 1.31 to 2.01, p < 0.01, I 2 = 0%). Subgroup analyses showed that ACT significantly improved short-term cessation rates compared with behavioral support (RR = 1.60, 95% CI [1.27, 2.02], p < 0.01, I 2 = 0%), while, compared with the blank control, ACT significantly increased smoking cessation rates across three different time points (postintervention: RR = 3.11, 95% CI [2.13, 4.54], p < 0.01, I 2 = 0%; medium-term follow-up: RR = 2.55, 95% CI [1.32, 4.93], p < 0.01; long-term follow-up: RR = 3.33, 95% CI [1.66, 6.68], p < 0.01). Narrative synthesis suggested that compared with behavioral therapy, ACT may confer benefits in improving psychological outcomes, while compared with the blank control, it may also reduce daily cigarette consumption and nicotine dependence, and enhance psychological outcomes.
Acceptance and commitment therapy may be a beneficial approach for improving cessation rates, enhancing smoking cessation behaviors, and promoting psychological well-being among adult smokers. However, the quality of the included evidence was limited, thereby weakening the strength of these findings. Future rigorously designed trials with larger sample sizes, particularly those comparing ACT against other smoking cessation interventions, are warranted to further confirm its effects.
Pressure injuries remain a significant concern in military hospital settings, leading to increased morbidity and healthcare costs. Understanding the interplay of multiple risk factors is critical for effective prevention. To identify key risk factors and their combined effects on pressure injury development among inpatients in multi-centre military hospitals using factor analysis. A cross-sectional study was conducted involving 4876 inpatients across multiple military hospitals. Data were collected on 15 potential risk factors, including incontinence, care dependency, mobility limitations, comorbidities, medication use, nutritional status, and demographics. Factor analysis with principal component analysis and varimax rotation was applied, and maximum canonical correlation coefficients were calculated to evaluate the predictive contribution of single and combined factors. Single-factor analysis identified incontinence as the strongest predictor (MaxCanonicalCorr = 0.50126), followed by care dependency (0.31982) and bedridden status (0.30061). Two-factor analysis revealed incontinence combined with care dependency as the highest-performing model (MaxCanonicalCorr = 0.50867). Three-factor models incorporating incontinence, health conditions, and care dependency achieved the greatest predictive capacity (MaxCanonicalCorr = 0.5157), demonstrating that multi-factor interactions enhance risk prediction beyond single-factor effects. Incontinence is the primary modifiable risk factor for pressure injury in military hospital inpatients. Integrating continence management with assessments of functional status and comorbidities can improve early identification of high-risk patients and guide targeted preventive strategies.

Percutaneous Bunnell repair and open modified Kessler repair remain debated options for acute Achilles tendon rupture (AATR). We retrospectively compared a minimally invasive percutaneous Bunnell technique (Group A) with an open modified Kessler repair (Group B) within a standardized early functional rehabilitation (EFR) protocol at a single center. Fifty-five adults with closed AATR treated between January 2021 and December 2022 were analyzed (Group A, n = 25; Group B, n = 30). Between-group comparisons used Welch t tests for continuous variables and χ² or Fisher exact tests for categorical variables; American Orthopaedic Foot & Ankle Society (AOFAS) and Achilles Tendon Total Rupture Score (ATRS) were assessed at 12 and 24 weeks, with Holm adjustment applied within each scale. Compared with Group B, Group A had shorter operative time (56.6 ± 15.1 vs 68.2 ± 23.2 minutes; mean difference −11.6; 95% CI −22.05 to −1.15; P = 0.030), less intraoperative blood loss (28.4 ± 8.4 vs 74.7 ± 19.4 mL; −46.3; 95% CI −54.22 to −38.38; Pby Melissa M.

BackgroundWhile recent data on vitamin A deficiency (VAD) prevalence is lacking, the 2004 Côte d’Ivoire Nutrition and Mortality Survey reported that 26.7% of children aged 6–59 months were affected by VAD, and approximately 60% were at risk. Since 2016, the government has transitioned from mass campaigns to routine vitamin A supplementation (VAS) delivery integrated into health services. However, evidence on the cost-effectiveness of the routine distribution approaches is limited. This study evaluated the cost, coverage, and cost-effectiveness of three routine VAS delivery strategies across two health districts in northern Côte d’Ivoire.
MethodsA mixed-methods study evaluated three routine VAS delivery strategies – routine-fixed, advanced community-based, and catch-up – across two health districts, Ferkessédougou and Niakaramadougou, in northern Côte d’Ivoire. The quantitative cost data were collected via a structured tool covering six cost categories: planning, procurement, training, social mobilization, distribution, and supervision. VAS coverage was assessed through a post-event coverage survey (PECS) via a two-stage cluster sampling methodology. A cost-effectiveness analysis determined the cost per child supplemented, the cost per DALY averted, and a sensitivity analysis tested the robustness of the findings under different cost scenarios.
ResultsThe total program cost for July-December 2023 was 25.5 million FCFA, with personnel costs comprising over 70% of expenditures. In Ferkessédougou, the routine advanced community-based strategy was the most cost-effective, at 458 FCFA per child in rural areas (versus 596 FCFA for the routine-fixed facility-based approach in the same area). In Niakaramadougou, the December catch-up was more cost-effective in rural areas (606 FCFA per child) than the routine-fixed approach (714 FCFA). Across both districts combined, the routine-fixed strategy averaged roughly 651 FCFA per child supplemented, and the cost per DALY averted ranged from 30,093 FCFA (advanced strategy in Ferkessédougou) to 89,550 FCFA (catch-up Jul 2023 in Niakaramadougou) – all below Côte d’Ivoire’s cost-effectiveness threshold (0.5 x GDP per capita; approximately USD 1,265).
ConclusionAll three strategies were cost-effective, though the advanced community-based strategy achieved the best balance of reach and efficiency. Scaling advanced strategies within health system constraints may enhance sustainability and coverage in low-resource settings.
The ‘time-limited trial’ for patients with critical illness is a collaborative plan made by clinicians, patients and families to use life-sustaining therapies for a defined duration. After this period, the patient’s response to therapy informs decisions about continuing recovery-focused care or transitioning to comfort-focused care. The promise of time-limited trials to help navigate the uncertain limits and benefits of life-sustaining therapies has been extensively discussed in the palliative and critical care literature, leading to their dissemination into clinical practice. However, we have little evidence to guide clinicians in how to conduct time-limited trials, leading to substantial variation in how and why they are currently used. The overall purpose of this study is to characterise the features of an optimal time-limited trial through a rich understanding of how they are currently shaping critical care delivery.
We are conducting an observational, multicentre, focused ethnography of time-limited trials in patients with acute respiratory failure receiving invasive mechanical ventilation in six intensive care units (ICUs) within five hospitals across the US. Study participants include patients, their surrogate decision makers and ICU clinicians. We are pursuing two complementary analyses of this rich data set using the open-ended, inductive approach of constructivist grounded theory and, in parallel, the structured, deductive methods of systems engineering. This cross-disciplinary, tailored approach intentionally preserves the tension between time-limited trials’ conceptual formulation and their heterogeneous, real-world use.
This study has been reviewed and approved by the University of Wisconsin Institutional Review Board (IRB) as the single IRB (ID: 2022-1681; initial approval date 23 January 2023). Our findings will be disseminated through peer-reviewed publication, conference presentations, and summaries for the public.

BackgroundProgressive 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.
MethodsA 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.
ResultsThree 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/discussionThis 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.
To investigate the current status of workplace spirituality and moral resilience among clinical nurses and to explore the relationship between these two factors, thereby providing a reference for developing strategies to enhance nurses' moral resilience.
A cross-sectional survey design.
From February to April 2025, a convenience sampling method was used to select 1680 nurses from ten hospitals in the Pingliang area of China. Data were collected using the general data questionnaire, Workplace Spirituality Scale(WSS). Furthermore, the relationship between workplace spirituality and moral resilience was analyzed.
A total of 1657 valid questionnaires were ultimately recovered, yielding an effective response rate of 98.63%. The mean score for workplace spirituality was 102.36 ± 21.65, and the mean score for moral resilience was 41.76 ± 6.31, both indicating a moderate level. A significant positive correlation was found between the two variables (r = 0.231, p < 0.05). Multivariate linear stepwise regression analysis revealed that monthly income, department, monthly night shifts, and workplace spirituality scores were significant predictors of moral resilience (p < 0.05).
The moral resilience of clinical nurses is at a moderate level. Enhancing workplace spirituality can contribute to improving their moral resilience.
To gain an in-depth understanding of the experience of elderly joint replacement patients in making surgical decisions and to identify the needs of patients in the decision-making process.
A qualitative study, semistructured interviews were used and analysed by Colaizzi’s seven-step method.
This study was conducted in the orthopaedics department of a tertiary hospital in Wuhan.
Eligible participants were aged 60 years or older, scheduled for elective joint replacement surgery, cognitively intact and voluntarily consented to participate in the study.
We conducted interviews with a total of 25 elderly patients who underwent joint replacement surgery. This study reveals three themes and eight subthemes regarding the surgical decision-making experiences of elderly patients undergoing joint replacement. The three themes summarise three stages of the decision-making experience, respectively, trade-offs before decisions, feelings during decision-making and expectations after the decision. In the first stage, three subthemes were identified: (1) weighing the surgical risks and benefits, (2) assessment of medical proficiency and (3) low patient involvement in decision-making. In the second stage, three subthemes emerged: (1) internal fear, (2) self-doubt and (3) a heavy burden. In the third stage, two subthemes were identified: (1) a recovery process filled with confidence and (2) a desire for improved quality of life.
This study delves deep into the experiences of elderly patients undergoing joint replacement surgery during the surgical decision-making process. It provides a theoretical basis for decision-making assistance for elderly joint replacement patients, which is conducive to reducing patients’ decision-making conflicts and enhancing their decision-making capabilities.
To examine demographic, behavioural and clinical determinants of self-rated health (SRH) among Iranian adults with hypertension (HTN), with a particular focus on the association between blood pressure (BP) control and perceived health.
National cross-sectional analysis of 15 predictors spanning demographic, lifestyle and clinical domains.
2021 Iranian STEPwise Approach to Non-communicable Disease Risk Factor Surveillance, a nationally representative survey.
A total of 8812 adults with HTN (mean age 56.97 years; 57% female). Controlled HTN was defined as systolic blood pressure
The primary outcome was SRH, measured on a standard EuroQol-Visual Analogue Scale (0–100).
Controlled HTN was independently associated with higher SRH scores (β=1.31, 95% CI 0.07 to 2.54). Positive predictors of SRH included male gender (β=4.34, 95% CI 3.38 to 5.31), higher wealth (richest vs poorest: β=5.52, 95% CI 4.06 to 6.97), sufficient physical activity (β=4.38, 95% CI 3.48 to 5.28), healthier diet (β=3.06, 95% CI 1.99 to 4.14) and complementary insurance coverage (β=2.50, 95% CI 0.63 to 4.37). Significant negative predictors included diabetes mellitus (β=–4.23, 95% CI –5.59 to –3.26), dyslipidaemia (β=–3.61, 95% CI –4.62 to –2.59), people who smoke (β=–4.21, 95% CI –5.64 to –2.78) and older age. Notably, antihypertensive medication use showed one of the strongest negative associations with SRH (monotherapy: β=–4.83; combination therapy: β=–5.28), likely reflecting underlying disease severity and treatment burden.
Better SRH among hypertensive adults was associated with controlled BP, healthier lifestyle patterns and higher socioeconomic status. Conversely, comorbidities, smoking, older age and antihypertensive treatment were linked to poorer perceived health. Integrating SRH screening into HTN management may help identify vulnerable individuals and inform targeted interventions addressing behavioural and socioeconomic determinants of health.

ObjectiveInvestigate the Knowledge-Attitude-Practice (KAP) of students from Medical College towards emerging infectious diseases, and assess their impact, can provide a scientific basis and practical guidance for enhancing medico’s prevention and control capabilities.
MethodsA total of 2,395 participants from various grades and majors at Medical University were randomly selected using a stratified cluster sampling method. This cross-sectional study was conducted between April 25 and May 31, 2020, using a self-administered questionnaire developed on the Wenjuanxing platform to assess COVID-19-related knowledge, attitudes, and practices (KAP) among medical students.
ResultsA total of 2,245 participants (aged 16–28 years) were included in the study, coming from five medical disciplines: Clinical Medicine, Preventive Medicine, Nursing, Clinical Pharmacy, Health Inspection and Quarantine. The average scores for the COVID-19 epidemiological knowledge and the control measures for the epidemic were 4.92 ± 1.03 and 4.50 ± 0.78, respectively. Among them, the scores of epidemiological knowledge exhibited significant differences in sex, nation, type of dwelling place, major, grade, annual per capita household income, and age. The scores of preventive knowledge significantly differed by sex, major, grade, physical condition, and age. Further, behavioral data indicated that 96.0% of the students thought the pandemic had severely affected their daily life, while >90% maintained consistent mask usage and >80% insisted on health-protective practices. Practice scores finally varied significantly by sex, family structure, and ethnicity.
ConclusionsAltogether, medical students possess certain basic knowledge in controlling emerging infectious diseases, but some still generally suffer from insufficient cognitive depth and anxiety. Colleges can systematically enhance students’ rational cognitive level which include offering specialized courses as well as promoting cutting-edge research achievements, and through standardized operations stabilize their psychological states.
Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide, with most Chinese patients diagnosed at a locally advanced stage. Neoadjuvant chemotherapy (NAC) is increasingly used to improve resectability and survival. Laparoscopy-assisted distal gastrectomy (LADG) provides short-term recovery benefits compared with open distal gastrectomy (ODG), but its safety and oncologic efficacy following NAC remain uncertain. This trial aims to determine whether LADG is non-inferior to ODG in terms of long-term survival outcomes in patients with locally advanced distal gastric cancer (LAGC) after NAC.
This is a multicentre, randomised, controlled, non-inferiority trial conducted at high-volume GC centres in China. Eligible patients (aged 18–75 years; cT3–4a, N0/+, M0) with histologically confirmed distal gastric adenocarcinoma who have completed standard NAC will be randomised 1:1 to LADG or ODG with D2 lymphadenectomy. Surgical quality will be standardised through operative manuals, intraoperative video recording and central auditing. The primary endpoint is 3-year disease-free survival. Secondary endpoints are 3- and 5-year overall survival. A total of 998 patients (499 per arm) will be enrolled, providing 80% power to test non-inferiority with an absolute 8% margin, accounting for 15% attrition. Analyses will follow the intention-to-treat principle, with Cox models used for survival comparisons and subgroup analyses according to nodal status, tumour size and pathological response.
This trial has been reviewed and approved by the Biomedical Ethics Committee of West China Hospital, Sichuan University (Approval No. 2025 (865), 16 July 2025). Written informed consent will be obtained from all participants. The results will be disseminated through peer-reviewed journals and international conferences, providing high-level evidence to guide the surgical management of LAGC after NAC.

Adolescent mental health and wellbeing are of growing concern globally with increased incidence of mental health disorders in young people. BrainWaves provides a framework for relevant and diverse research programmes into adolescent mental health and wellbeing that can translate into practice and policy. The research programme is a partnership with schools centred on establishing a large (n > 50,000) cohort and trials platform. Reported here is the BrainWaves cohort pilot study. This was designed as proof-of-concept for our recruitment and data capture pipelines, and for cost-modelling. A network of research schools was recruited and a computer-driven questionnaire administered. The eligible population was 16 + year olds who were attending the research schools. Of 41 research schools, 36 (88%) participated over one three-week and one four-week data collection period. From an eligible population of 33,531 young people, 16,010 (48%) attended the study lesson and created an account. Of the 16,010 (100%) who created an account, 15,444 (96%) consented to participate, 9,321 (60%) consented to linkage of research data with educational records, and 6,069 (39%) consented to linkage of research with school/college attendance data. Participants were aged 16–19 years, 59% female, and 76% White. Higher levels of anxiety and depression were found in females than males. Higher levels of media-based social networking were found in females, whereas higher levels of media-based gaming were found in males. Females were more likely to report insufficient sleep whilst males were more likely to report high levels of exercise. This study confirmed an ability to recruit at pace and scale. Whilst the response-rate does not indicate a representative sample, the demographics describe an inclusive and diverse sample. Data collected confirmed findings from previous studies indicating that the electronic data collection methods did not materially bias the findings. Initial cost-modelling suggests these data were collected for around £20 per participant.Introducción: La Inseguridad Alimentaria (IA), vinculada a la pobreza, favorece el consumo de alimentos poco nutritivos y aumenta el riesgo de enfermedades crónicas. Su comprensión es clave en enfermería comunitaria y escolar para fomentar hábitos saludables desde edades tempranas. Objetivo: Analizar la relación entre el Nivel Socioeconómico (NSE) e IA en Estudiantes de Una Universidad Pública del Norte de Sinaloa, México. Metodología: Estudio cuantitativo, descriptivo, correlacional y transversal en estudiantes de 18 a 25 años inscritos en un programa de Licenciatura. Los participantes fueron seleccionados a partir de un muestreo aleatorio simple. La muestra fue de 311 estudiantes. Se aplicó una cédula de datos sociodemográficos, el cuestionario AMAI y la Escala Latinoamericana y Caribeña de Inseguridad Alimentaria. Resultados: En los hogares sin presencia de menores, la IA severa presenta mayor prevalencia en NSE medio (29,6%) y alto (32,5%). Se observó una correlación positiva y significativa entre el NSE y la IA, tanto en hogares sin integrantes menores de edad (rs = 0,263, p < 0,01), como en aquellos con menores (rs = 0,231, p < 0,01). Conclusiones: En esta población de estudiantes universitarios, se observó que a medida que aumenta el NSE, también lo hace la IA, lo que sugiere que esta no es exclusiva de los sectores socioeconómicos bajos, sino que también afecta de forma considerable a los niveles medio y alto. La persistencia de esta problemática en todos los niveles sugiere que factores estructurales, más allá del ingreso, como el acceso a alimentos nutritivos, educación alimentaria y estabilidad laboral, podrían influir significativamente.
ABSTRACT
Introduction: Food insecurity (FI), linked to poverty, promotes the consumption of unhealthy foods and increases the risk of chronic diseases. Understanding it is key in community and school nursing to foster healthy habits from an early age. Objective: To analyze the relationship between socioeconomic status (SES) and FI in students at a public university in Northern Sinaloa, Mexico. Methodology: A quantitative, descriptive, correlational, and cross-sectional study was conducted with students aged 18 to 25 years enrolled in an undergraduate program. Participants were selected using simple random sampling. The sample consisted of 311 students. A sociodemographic data form, the AMAI questionnaire, and the Latin American and Caribbean Food Insecurity Scale were administered. Results: In households without children, severe FI was more prevalent in middle (29.6%) and high (32.5%) SES groups. A positive and significant correlation was observed between socioeconomic status (SES) and food insecurity (FI), both in households without minor members (rs = 0.263, p < 0.01) and in those with minors (rs = 0.231, p < 0.01). Conclusions: In this population of university students, it was observed that as SES increases, so does FI, suggesting that it is not exclusive to low socioeconomic sectors, but also significantly affects middle and high levels. The persistence of this problem at all levels suggests that structural factors, beyond income, such as access to nutritious food, nutrition education, and job stability, could have a significant influence.

Dysregulated serum chloride levels are prevalent in critically ill patients. However, their clinical impact remains unclear. This first systematic review and meta-analysis quantified the prevalence of hypochloremia and hyperchloremia, and their associations with mortality and acute kidney injury (AKI) in critically ill populations. We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies reporting hyperchloremia prevalence or outcomes in adult ICU patients until August 2025. Statistical analyses were conducted using Stata v16.0, and study quality was assessed using the Newcastle-Ottawa Scale. 34 studies (n = 175,021 patients) were included. The aggregated prevalence of hyperchloremia was 34% (95% CI [26%−43%]) and hypochloremia was 14% (95% CI [1%−28%]). Meta-analysis demonstrated that both hyperchloremia and hypochloremia were significantly associated with increased mortality, conferring a 28% (OR = 1.28, 95% CI [1.08–1.52]) and 55% (OR = 1.55%, 95% CI [1.33–1.81]) elevated risk for mortality, respectively. Crucially, a dose-response analysis revealed a non-linear relationship between serum chloride levels and mortality, confirming that the risk is independently elevated at both extremes. Furthermore, hyperchloremia was linked to an increased risk of AKI (OR = 1.40, 95% CI [1.07–1.85]). These findings establish dysregulated serum chloride as a common and clinically significant biomarker, underscoring the necessity of monitoring and managing both high and low chloride levels in critically ill patients. Future large-scale studies are warranted to validate these results and elucidate the mechanistic pathways linking chloride dysregulation to such adverse outcomes.Phasix mesh is a fully resorbable synthetic mesh for use in clean and contaminated ventral incisional hernia repairs. Long-term absorbable Phasix mesh appears to be a safe and promising device in incisional hernia repair, with low recurrence rates; however, data on long-term complications after surgery, particularly after the resorption period of the mesh, are scarce.
This protocol describes a study of several European registries on the use of a Phasix mesh in incisional hernia repair. The primary endpoint of the study is long-term complications at 2–5 year follow-up after mesh implantation, with secondary endpoints including hernia recurrence and complications during short-term follow-up.
Ethical approval was not required for this protocol as the study is based on anonymised registry data collected with prior patient consent in each registry. Each participating registry has its own ethical approval process, and this study will adhere to those regulations. The results will be disseminated through peer-reviewed publications and conference presentations.
The MD Anderson Oropharynx Cancer (MDA-OPC) cohort is a unique single-institution, prospective longitudinal cancer cohort. The cohort aims to enhance the therapeutic index of OPC management by supporting data needs for independent investigators to conduct rigorous observational studies examining exposures and factors associated with acute and late toxicities, cancer progression, recurrence, new malignancies and quality of life in OPC survivors.
A total of 1811 patients with OPC with a minimum follow-up of 6 months have been consented to our prospective registry between 18 March 2015 and 29 December 2023. Clinical and treatment (Tx) data are available on all patients, including previously untreated patients (1443, 80%). Most previously untreated patients (97%) consented to longitudinal patient-reported outcomes and functional assessments for critical time points including pre-Tx, during-Tx and post-Tx at 3–6 months, 12 months, 18–24 months and annually up to 5 years.
The median age for the MDA-OPC cohort is 66 years (range, 25–96) with the majority being male (89%), white (92%) and with human papillomavirus (HPV)/p16-associated OPC (88%) primarily located in the tongue base or tonsil (90%). For previously untreated patients, 79% were diagnosed with stage I/II disease, and nearly half underwent curative intent chemoradiation. Overall survival was significantly higher for HPV/p16-associated OPC at 1 year (98% vs 93%) and 5 years (83% vs 54%; p
Future work includes expansion of the MDA-OPC cohort and survivorship surveillance to 10 years under the recently funded OPC-SURVIVOR research programme (P01CA285249), which aims to identify non-invasive, clinic-ready biomarkers and examine novel phenotypes and mechanistically matched mitigation strategies for latent OPC sequelae. Additionally, we aim to expand our advanced data infrastructure by integrating large data streams from parallel clinical trials and imaging registries.

BackgroundMicroglia polarization plays a crucial role in the progression of cerebral ischemia-reperfusion injury (CIRI), but the mechanisms remain largely undefined. The preset study aimed to investigate the mechanism of microglia polarization following CIRI.
MethodsCIRI was modeled in C57BL/6J mice through middle cerebral artery occlusion-reperfusion and in BV2 cells via oxygen and glucose deprivation/reoxygenation. Reverse transcription-quantitative PCR, western blotting, flow cytometry and fluorescence staining were used to detect the expression levels of key proteins associated with microglia polarization, as well as the expression of TNFAIP3 and RACK1. The interaction between TNFAIP3 and RACK1 was verified by co-immunoprecipitation. TNFAIP3 or RACK1 gene interference (overexpression and/or silencing) was employed to examine the role of the TNFAIP3/RACK1 axis in microglia polarization following CIRI.
ResultsThe results revealed that Arg-1 expression decreased, inducible nitric oxide synthase expression increased and TNFAIP3 was upregulated 24 h after CIRI. Furthermore, TNFAIP3 interacted with RACK1 to deubiquitinate and increase the expression of RACK1. These results indicate that knocking down either TNFAIP3 or RACK1 promotes microglia M1 polarization, and overexpression of RACK1 can promote microglia M2 polarization. RACK1 exerts its neuroprotective effects through NF-κB, as demonstrated by the use of NF-κB inhibitors.
ConclusionThe present findings indicate that TNFAIP3 inhibits M1 microglial polarization via deubiquitination of RACK1 after CIRI, RACK1 exerts its effects through NF-κB.

In UAV aerial photography scenarios, targets exhibit characteristics such as multi-scale distribution, a high proportion of small targets, complex occlusions, and strong background interference. These characteristics impose high demands on detection algorithms in terms of fine-grained feature extraction, cross-scale fusion capability, and occlusion resistance.The YOLOv11s model has significant limitations in practical applications: its feature extraction module has a single semantic representation, the traditional feature pyramid network has limited capability to detect multi-scale targets, and it lacks an effective feature compensation mechanism when targets are occluded.To address these issues, we propose a UAV aerial small target detection algorithm named UAS-YOLO (Universal Inverted Bottleneck with Adaptive BiFPN and Separated and Enhancement Attention module YOLO), which incorporates three key optimizations. First, an Adaptive Bidirectional Feature Pyramid Network (ABiFPN) is designed as the Neck structure. Through cross-scale connections and dynamic weighted fusion, ABiFPN adjusts weight allocation based on target scale characteristics, focusing on enhancing feature integration for scales related to small targets and improving multi-scale feature representation capability. Second, a Separated and Enhancement Attention Module (SEAM) is introduced to replace the original SPPF module. This module focuses on key target regions, enhances effective feature responses in unoccluded areas, and specifically compensates for information loss in occluded regions, thereby improving the detection stability of occluded small targets. Third, a Universal Inverted Bottleneck (UIB) structure is proposed, which is fused with the C3K2 module to form the C3K2_UIB module. By leveraging dynamic channel attention and spatial feature recalibration, C3K2_UIB suppresses background noise; although this increases parameters by 34%, it achieves improved detection accuracy through efficient feature selection, striking a balance between accuracy and complexity.Experimental results show that on the VisDrone2019 dataset and the TinyPerson dataset from Kaggle, the mean Average Precision (mAP) of the algorithm is increased by 4.9 and 2.1 percentage points, respectively. Moreover, it demonstrates greater advantages compared to existing advanced algorithms, effectively addressing the challenge of small target detection in complex UAV scenarios.
