MATERIALS AND METHODS: 93 patients with diagnosed carpal tunnel syndrome subjected to complete the self-report DASH-KU and patient rated wrist\hand evaluation PRWHEKU questionnaire during two consecutive assessments with a 24-hour interval before any intervention.

RESULTS: DASH-KU questionnaire had excellent internal consistency (Cronbach's alpha = 0.99) and test-retest reliability (intra-class correlation coefficient =0.99). A strong correlation between the DASH-KU score and the PRWHE tool (r=0.792) demonstrated acceptable construct validity of DASH-KU. Bland-Altman plot showed good agreement between the two assessments of DASH-KU, and no floor (3%) nor ceiling effects (0%) were observed. Factor analysis showed that the DASH-KU scale had a high acceptable adequacy (adequacy index = 0.700) and a significant sphericity (p<0.001). The analysis showed a major factor that accounted for 40% of the observed variance with an eigenvalue of 13.14. In addition, five items model also explained 81.23% of the DASH-KU scale variance. However, the responsiveness of DASH-KU was suboptimum, which can be linked to the short 24-hour interval between measurements.

METHOD: This study proposes a combination of decision tree and logistic regression techniques to model crash severity (injury vs. noninjury), because the combined approach allows the specification of nonlinearities and interactions in addition to main effects. Both a scobit model and a random parameters logit model, respectively accounting for an imbalance response variable and unobserved heterogeneities, are tested and compared. The study data set contains a total of 5 years of crash data (2008-2012) on selected mountainous highways in Malaysia. To enrich the data quality, an extensive field survey was conducted to collect detailed information on horizontal alignment, longitudinal grades, cross-section elements, and roadside features. In addition, weather condition data from the meteorology department were merged using the time stamp and proximity measures in AutoCAD-Geolocation.

RESULTS: The random parameters logit model is found to outperform both the standard logit and scobit models, suggesting the importance of accounting for unobserved heterogeneity in crash severity models. Results suggest that proportion of segment lengths with simple curves, presence of horizontal curves along steep gradients, highway segments with unsealed shoulders, and highway segments with cliffs along both sides are positively associated with injury-producing crashes along rural mountainous highways. Interestingly, crashes during rainy conditions are associated with crashes that are less likely to involve injury. It is also found that the likelihood of injury-producing crashes decreases for rear-end collisions but increases for head-on collisions and crashes involving heavy vehicles. A higher order interaction suggests that single-vehicle crashes involving light and medium-sized vehicles are less severe along straight sections compared to road sections with horizontal curves. One the other hand, crash severity is higher when heavy vehicles are involved in crashes as single vehicles traveling along straight segments of rural mountainous highways.

Materials and Methods: We identified and performed five primary reverse total shoulder arthroplasties between 1 May 2019 and 1 June 2020. All patients were contactable and available for analysis. Assessment of functional outcomes was performed using the Constant-Murley score, the patient satisfaction score (PSS), and imaging studies. The mean follow-up from operation to the time of reporting was 9.6 months (range, 3 to 14 months).

Results: The median age for our patients was 58 years (±11.91). The most common indication for surgery was post-traumatic arthritis, followed by rotator cuff arthropathy and osteoarthritis. The mean Constant score improved from 9.0 pre-operatively to 52.3 post-operatively at a mean of 9.6 months. The majority of the patients were satisfied with the surgery as the post-operative range of motion, especially anterior elevation and abduction, improved in four of our patients and there were no short-term complications, for example, of infection or revisions, reported at the last follow-up.

Methods: Nineteen adolescent state-level weightlifters were assigned into isokinetic or isotonic groups. All participants were recruited from a pool of weightlifters with standardized training program provided by their coach. Series of immunological tests were carried out before the commencement, immediately upon the completion, and a month after the cessation of the additional training program to evaluate total leukocytes and lymphocytes count.

Results: The results revealed a significant time and group interaction and main effects of time on mean total leukocytes (P < 0.05). Mean total leukocytes count at posttest decreased in both groups. In isotonic group, it was further decreased following 1 month of training cessation (P < 0.05) but not in the isokinetic group. However, the decrement was not high and the values were in the normal range. No significant time and group interaction was observed in total lymphocytes and its subsets count.

Methods: Overall, 142 participants (height: 1.80 ± 0.15 m, BMI: 26.08± 6.70, age: 35±15 yr) with at least a year of working experience completed both questionnaires, the online ROSA and the Cornell musculoskeletal discomfort, in 2016 in Malaysia.

Results: Relationship between the total scores of both questionnaires for lower back, shoulder and neck pain were significant but exhibited a weak to moderate relationship (range of r values from 0.012 (CI 95%, -0.153-0.176) to 0.503 (CI 95%, 0.369-0.616).
