Article Abstract
Background: Low back pain (LBP) is a significant musculoskeletal disorder with multifactorial causes, affecting workforce productivity globally. Personnel working on islands face heightened LBP risk due to intensive training (e.g., heavy lifting, prolonged standing) and harsh environmental conditions (high temperature, humidity, solar radiation). Existing LBP questionnaires, such as the Roland-Morris Disability Questionnaire and Oswestry Disability Index, lack specificity for island personnel's unique challenges. This study aimed to develop and validate the Low Back Pain Questionnaire (LBPQ) tailored to this population, aligning with the biopsychosocial medical model.
Methods: The LBPQ development followed a six-step process: conceptual definition, item generation, purification, dimension extraction, and reliability/validity testing. Through literature review, expert discussions, and interviews with 30 personnel working on islands, a 50-item initial scale was refined to 25 items across five dimensions: Pain Severity, Training, Daily Life, Psychological Impact, and Island Specificity. The final scale was administered to 600 personnel working on islands (experimental group) and 600 personnel working on land (control group). Reliability was assessed via Cronbach's α, while validity included factor analysis, convergent/discriminant validity tests, and correlation with the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI).
Results: The LBPQ demonstrated excellent reliability for personnel working on islands (Cronbach's α = 0.978) and good validity, with a KMO value of 0.967 and a cumulative variance contribution rate of 93.322%. Confirmatory factor analysis showed optimal model fit (χ/d = 1.354, CFI = 0.997, RMSEA = 0.024). Convergent and discriminant validity were superior in the island group compared to the control group. Strong correlations were observed with VAS ( = 0.675) and ODI ( = 0.824), confirming alignment with established scales.
Conclusion: The LBPQ is a reliable and valid tool for assessing LBP in personnel working on islands, addressing their unique environmental and occupational risks. It enhances clinical understanding of LBP severity and psychosocial impacts, enabling targeted prevention and intervention strategies. Future research should validate its applicability across diverse island environments and further refine its brevity.

Importance: Caregivers of community-dwelling older adults play a protective role in emergency department (ED) care transitions. When the demands of caregiving result in caregiver burden, ED returns can ensue.
Objective: To develop models describing whether caregiver burden is associated with ED revisits and hospital admissions up to 30 days after discharge from an initial ED visit.

Purpose: To investigate the role of personal risk factors in the occurrence of the vascular, neurological and fibroproliferative disorders of the hand-arm vibration syndrome (HAVS) in workers groups exposed to hand-transmitted vibration (HTV).
Methods: HAVS prevalence and incidence data were pooled across a series of cross-sectional studies (total sample: 1272 HTV workers, 579 controls) and prospective cohort studies (total sample: 377 HTV workers, 138 controls) conducted in Central and North-Eastern Italy. The pooled studies included detailed individual-level information about HTV exposure, personal risk factors, medical comorbidities and HAVS disorders.

Modulating the electronic structure of catalysts to maximize their power holds the key to address the challenges faced by zinc-iodine batteries (ZIBs), including the shuttle effect and slow redox kinetics at the iodine cathode. Herein, oxygen vacancies is innovatively introduced into CoO lattice to create high-spin-state Co active sites in nonstoichiometric CoO nanocrystals supported by carbon nanofibers (H-CoO/CNFs). This simple strategy intensifies crystal field splitting of Co 3d orbitals, optimizing the spin-orbital coupling between Co 3d orbitals and iodine species.

Burnout and perceived work ability (PWA) are critical factors influencing teachers' professional well-being and effectiveness. The potential bidirectional relationship between these constructs remains underexplored, particularly in primary and lower secondary school teachers. This study examines the reciprocal relationship between burnout and PWA among teachers over time, using the job demands-resources (JD-R) model and the conservation of resources (COR) theory.
