BACKGROUND: Very few articles, comprehensively, investigated musculoskeletal pain symptoms (MPS) among wide variety of allied health professions (AHP) students. OBJECTIVES: : This study aimed to investigate the prevalence of MPS and their associated factors among different AHP majors’ students. METHOD: A cross-sectional design was conducted. A sample of AHP students from nine majors ( n = 838, Mean age = 21.3 years) completed a validated structured self-administrated questionnaires including Nordic Musculoskeletal Questionnaire, Depression Anxiety Stress Scale (DASS 21), and specific questions regarding demographics and life style. MPS prevalence rate were compared between males and females and between majors. Logistic regression was conducted to identify predictors of MPS. RESULTS: MPS in neck, lower back, and shoulder 12-month were the most prevalent (67.1%, and 61.4%, 58.8% respectively). MPS prevalence was significantly higher in females and statistically different among majors. MPS were significantly associated with increased clinical training load, mental stress symptoms, and smartphone average use time. CONCLUSIONS: MPS in AHP students are prevalent and statistically higher among females. Students are advised to adhere to different conservative precautions and follow prevention programs. Future studies are needed to assess actual mechanisms causing MPS among AHP students and designing effective prevention programs specific to AHP students.

Small animal imaging provides diverse methods for evaluating tumor growth and acute response to therapy. This study compared the utility of non-invasive optical and ultrasound imaging to monitor growth of three diverse human tumor xenografts (brain U87-luc-mCherry, mammary MCF7-luc-mCherry, and prostate PC3-luc) growing in nude mice. Bioluminescence imaging (BLI), fluorescence imaging (FLI), and Power Doppler ultrasound (PD US) were then applied to examine acute vascular disruption following administration of arsenic trioxide (ATO). During initial tumor growth, strong correlations were found between manual caliper measured tumor volume and FLI intensity, BLI intensity following luciferin injection, and traditional B-mode US. Administration of ATO to established U87 tumors caused significant vascular shutdown within 2 hrs at all doses in the range 5 to 10 mg/kg in a dose dependant manner, as revealed by depressed bioluminescent light emission. At lower doses substantial recovery was seen within 4 hrs. At 8 mg/kg there was >85% reduction in tumor vascular perfusion, which remained depressed after 6 hrs, but showed some recovery after 24 hrs. Similar response was observed in MCF7 and PC3 tumors. Dynamic BLI and PD US each showed similar duration and percent reductions in tumor blood flow, but FLI showed no significant changes during the first 24 hrs. The results provide further evidence for comparable utility of optical and ultrasound imaging for monitoring tumor growth, More specifically, they confirm the utility of BLI and ultrasound imaging as facile assays of the vascular disruption in solid tumors based on ATO as a model agent.

Benzyloxy-2-chloroquinoline was reacted with fluorine-18 labelled potassium cryptand fluoride, followed by catalytic hydrogenation to prepare [¹⁸F]2-fluoroquinolin-8-ol in high radiochemical yields (30%; uncorrected and relative to [¹⁸F]-fluoride), specific activities (>1 Ci μmol⁻¹) and radiochemical purities (>99%) within 70 min; PET-CT imaging with this new radiotracer in double transgenic mice shows excellent promise for imaging Alzheimer's disease.

Among healthcare workers, nurses are considered the core of healthcare auth–info services in healthcare facilities because of their responsibilities and duties toward patients. All healthcare professionals, especially nurses, must be completely knowledgeable about the hazards of ionizing radiation, and the most effective radiation protection techniques. This study assessed the attitude and awareness toward radiation protection among final-year nursing students in the Fatima College of Health Sciences (FCHS) campuses. An online cross-sectional survey was conducted between March and April 2022. A total of 200 out of 224 female participants ranging from 18 to 30 years old agreed to participate in the study. The highest percentage of final-year nursing students did not attend any radiation protection course (52%). The results of the last section of the survey indicate a lack of awareness of basic radiation protection knowledge among final-year nursing students in FCHS campuses (less than 80%). The results showed a lack of knowledge and poor attitude toward radiation hazards and radiation protection from final-year nursing students in the FCHS. Formal education about basic radiation and radiation is recommended in the nursing program for safe clinical practice.
