Background Nurses working in radiological environments are frequently exposed to ionizing radiation and play an essential role in implementing radiation safety measures for both patients and healthcare professionals. Despite their close involvement in radiological procedures, evidence from several countries suggests that nurses may have inadequate knowledge of radiation protection principles and inconsistent safety practices. The objective of the study was to explore the knowledge, attitudes, and practices of nurses regarding radiation safety and identify educational needs among nursing staff working in the radiation related areas including wards, intensive care units, emergency departments, and operation theatres within a tertiary healthcare setting affiliated with Shri JJT University, Rajasthan, India. Methods A qualitative descriptive study was conducted using semi-structured, in-depth interviews with seventeen female nurses employed in radiology-related departments. Participants were recruited through purposive sampling. Interview transcripts were analyzed using thematic analysis guided by the Knowledge, Attitudes, Practices (KAP) framework. Data coding and theme development were performed manually, and findings were interpreted through an iterative analytical process. Results Five major themes emerged: (1) limited understanding of radiation fundamentals, (2) inadequate awareness of radiation protection measures, (3) inconsistent patient education practices, (4) recognition of occupational risks, particularly during pregnancy, and (5) a strong desire for continuing education. Participants demonstrated confusion regarding ionizing and non-ionizing radiation and incomplete knowledge of imaging modalities. Although most nurses acknowledged that radiation exposure could be harmful, their detailed understanding of dose limits, justification of procedures, and protection strategies was limited. Participants consistently expressed the need for additional training and improved radiation content within nursing curricula. Conclusion The findings indicate substantial gaps in radiation safety knowledge among nurses working in radiation-related clinical areas. Strengthening radiation protection education in undergraduate nursing programs and implementing regular continuing professional development initiatives may improve safety practices, patient education, and occupational protection for nursing staff.

Background The expanding scope of Physical Therapy research, coupled with rapid advances in digital health, artificial intelligence, implementation science, and evidence-based rehabilitation, has increased the demand for doctoral graduates with advanced research, leadership, and interdisciplinary competencies. Despite this evolution, published guidance describing systematic and evidence-informed approaches to developing doctoral curricula in Physical Therapy Sciences remains limited. This study aimed to develop and externally validate an evidence-informed doctoral curriculum framework through systematic needs assessment, international benchmarking, competency mapping, and constructive alignment. Methods A multiphase evidence-informed curriculum development methodology was employed. The study comprised seven sequential phases: (1) needs assessment and environmental analysis; (2) international benchmarking; (3) comparative curriculum analysis; (4) competency mapping ; (5) Curriculum framework development; (6) Curriculum refinement and quality assurance; and (7) external expert content validation. Twenty-four doctoral programmes from research-intensive universities in the United Kingdom, United States, Canada, and Australia were screened, of which eighteen met the predefined inclusion criteria for benchmarking. The proposed curriculum was subsequently evaluated by an international panel of twelve experts using a structured validation instrument, and content validity was assessed using item-level and scale-level Content Validity Indices. Results Benchmarking demonstrated substantial consistency across international doctoral programmes in advanced research methodology, biostatistics, research ethics, scientific writing, proposal development, and independent dissertation research. Comparative analysis further identified increasing emphasis on digital health, artificial intelligence, implementation science, interdisciplinary collaboration, research leadership, and knowledge translation as emerging doctoral competencies. These findings informed the development of a competency-based doctoral curriculum aligned with internationally recognised educational frameworks. External expert validation demonstrated high perceived relevance, competency alignment, curriculum structure, content appropriateness, and implementation feasibility of the proposed framework, with domain-specific agreement ranging from 92% to 100%. Minor recommendations related to curriculum sequencing and emerging digital competencies were incorporated without altering the overall doctoral curriculum framework. Conclusions This study presents an evidence-informed and high perceived relevance, alignment, and feasibility among an international expert panel that aligns Physical Therapy Sciences education with contemporary international educational standards and evolving rehabilitation research priorities. The proposed framework offers a transparent methodology for curriculum development that integrates systematic benchmarking, competency mapping, and expert validation, providing a practical model to inform the development or revision of doctoral programmes in Physical Therapy and related health professions. Future implementation studies are warranted to evaluate its educational effectiveness across diverse institutional settings.

Background Oral cancer remains a major public health concern in India, accounting for a significant proportion of cancer-related morbidity and mortality. Early detection through screening is considered an effective strategy for reducing disease burden and improving survival outcomes. Both community members and healthcare workers play an essential role in oral cancer screening programs; however, several barriers may affect the implementation and effectiveness of these screening initiatives. Understanding these factors is important for strengthening screening services and improving early detection efforts. Methods This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was retrospectively registered in PROSPERO (CRD420261422293). PubMed and Scopus were systematically searched for primary studies published in English from 01 January 2010 to 31 May 2026. Studies involving community members (adults aged 18 years and above) or healthcare workers that addressed barriers to oral cancer screening in India were included. Two reviewers independently screened the studies for eligibility. Data extraction was performed by one reviewer and independently cross-checked for accuracy by a second reviewer. Methodological quality was assessed using the Mixed Methods Appraisal Tool (MMAT) version 2018. A narrative synthesis of findings was performed. Results Eleven studies met the inclusion criteria, encompassing cross-sectional, qualitative, mixed methods, and quasi-experimental designs across multiple Indian states and union territories. Barriers were identified across community, healthcare worker, and health system levels using the WHO Health System Building Blocks framework and Three domains of the Social-Ecological Model: intrapersonal, interpersonal, and community. The principal barriers included limited knowledge and awareness, psychological and sociocultural constraints, household economic barriers, inadequate workforce capacity and training, fragmented referral pathways, weak health information systems, technological and infrastructure limitations, financial barriers, and governance constraints. Conclusions Oral cancer screening in India is impeded by multilayered, interconnected barriers that cannot be addressed through awareness campaigns alone. Integration of screening into Ayushman Bharat Health and Wellness Centres, structured capacity building for community health officers and ASHA workers, and concurrent demand-side interventions targeting stigma, economic hardship, and gender-based access constraints are essential. Sustained policy commitment and equity-focused programme design are urgently needed to reduce India's preventable oral cancer mortality.

Background Recovery after anterior cruciate ligament (ACL) reconstruction is typically monitored through patient-reported outcomes and periodic clinical assessments, which may not fully capture real-world functional performance. Smartphone-derived mobility data provide a passive and objective approach for evaluating daily activity and recovery. Purpose To examine associations between smartphone-derived mobility metrics and recovery outcomes in adults 3–12 months after primary ACL reconstruction and to identify distinct recovery phenotypes using mobility-based clustering. Methods This cross-sectional study included 120 adults who were 3–12 months post-primary ACL reconstruction and had at least 14 days of retrospective smartphone mobility data. Mobility variables included daily step count, activity volume and intensity (e.g., active minutes and walking bout duration), sedentary behavior, and walking-related metrics. Outcomes included pain (Numeric Rating Scale [NRS]), functional status (Knee Injury and Osteoarthritis Outcome Score [KOOS] Pain, Activities of Daily Living, and Sport/Recreation subscales), knee-related quality of life (ACL Quality of Life questionnaire [ACL-QoL]), and psychological measures including the Pain Catastrophizing Scale (PCS), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). Associations were evaluated using Pearson correlation and multivariable linear regression analyses. Recovery phenotypes were identified using unsupervised k-means clustering of mobility metrics. Results Higher daily step counts were independently associated with better KOOS-ADL scores (β = 0.48, p < 0.001), higher ACL-QoL scores (β = 0.45, p < 0.001), and lower pain intensity (β = − 0.39, p = 0.001). Three recovery phenotypes emerged: a high-activity/low-pain phenotype with superior function and minimal psychological distress, a moderate-activity/moderate-pain phenotype with intermediate outcomes, and a low-activity/high-pain phenotype characterized by reduced mobility, poorer function, greater pain, and higher pain catastrophizing. Significant gradients were observed across phenotypes for pain (NRS: 1.72–5.01), function (KOOS-Pain: 88.94–62.37), and pain catastrophizing (PCS: 8.52–24.91; all p < 0.001). Conclusions Smartphone-derived mobility metrics were significantly associated with recovery outcomes following ACL reconstruction. Mobility-based clustering identified distinct recovery phenotypes associated with meaningful differences in pain, function, and pain catastrophizing, highlighting the potential of passive mobility monitoring to support personalized rehabilitation strategies. However, given the variability in evaluation periods and uncontrolled surgical factors, future research employing standardized, long-term follow-ups is warranted.
