1.Correlates of Physical Activity Level among Hemodialysis Patients in Selangor, Malaysia
Malaysian Journal of Nutrition 2011;17(3):277-286
Introduction: There is mounting evidence demonstrating the importance of
adequate physical activity to promote better well-being among hemodialysis
patients. Available data pertaining to the levels of physical activity and its
determinants among hemodialysis patients is, however, scarce in Malaysia. The
objectives of this study are hence to determine the levels of physical activity and
it associated factors among hemodialysis patients. Methodology: A total of 70
subjects were recruited from three dialysis centres in Selangor. A face-to-face
interview was conducted to obtain socio-demographic data and subjects’
knowledge on dietary sources. Medical history, biochemical parameters and
weight status were obtained from medical records. Physical activity level (PAL)
was assessed using the Global Physical Activity Questionnaire (GPAQ). Results:
A total of 81.4% and 18.6% of the respondents had low and moderate PALs,
respectively. Thus, none of the respondents had high PAL. Serum creatinine,
education level, personal income and knowledge score on potassium-related
medical complications were factors found to correlate significantly with PAL.
Multiple linear regression analysis showed that higher PAL was predicted by a
lower knowledge score on dietary sodium source, higher education and higher
serum creatinine. Conclusion: Despite consistent documentation of the potential
positive impact of physical exercise on hemodialysis outcomes, the level of
physical activity remains low among these patients. It is hoped that these findings
can add to the existing body of knowledge and serve as a supporting document
for the formulation of appropriate interventions to improve the status of physical
activity among hemodialysis patients in Malaysia.

Study design: A cross sectional study among health care providers working at one hospital. Objective: To investigate the prevalence, the consequences and the risk factors associated with low back pain (LBP) among hospital staff. Materials and Methods: The study sample consisted of 931 health care providers who answered a pre established questionnaire including 30 items in two languages. Results: The cumulative life prevalence of LBP was 72.5% and the yearly prevalence was 56.9%. Chronic LBP prevalence was

OBJECTIVETo investigate the relationship between silica or silicosis and lung cancer in a large cohort of silicotic workers in Hong Kong.
METHODSAll workers with silicosis in Hong Kong diagnosed between 1981 and 1998 were followed up till the end of 1999 to ascertain their vital status and causes of death, using the corresponding mortality rates of Hong Kong males of the same period as external comparison. Standardized mortality ratios (SMR) for lung cancer and other major causes of death were calculated. Person-year method was used. Axelson's indirect method was performed to adjust for the confounding effect of smoking. Penalized smoothing spline (p-spline) models were used to evaluate the exposure-response relationship between silica dust exposure and lung cancer mortality.
RESULTSA total of 2789 newly diagnosed cases of silicosis were included in the cohort, with an overall 24 992.6 person-years of observations. The loss-to-follow-up rate was only 2.9%. Surface construction workers (51%) and underground caisson workers (37%) constituted the major part of the cohort. There were 853 silicotics observed with an average age at death of 63.8 years. The SMR for all causes and all cancers increased significantly. The leading cause of death was non-malignant respiratory diseases. About 86 deaths were from lung cancer, giving a SMR of 1.69 (95% CI: 1.35 approximately 2.09). The risk of lung cancer death among workers in surface construction, underground caisson, and entire cohort was reduced to 1.12 (95% CI: 0.89 approximately 1.38), 1.09 (95% CI: 0.82 approximately 1.42) and 1.56 (95% CI: 0.98 approximately 2.36) respectively, after indirectly adjusting for smoking.
RESULTSfrom P-spline model did not show a clear exposure-response relationship between silica dust (CDE and MDC) and lung cancer mortality.
CONCLUSIONThis cohort study did not show an increased risk of lung cancer mortality among silicotic workers. P-spline model does not support an exposure-response relationship between silica dust exposure and lung cancer mortality.

Objective:
To examine the impact of maternal risky behaviors on the behaviors of children born to adolescent and young mothers.
Methods:
Adolescents and young Chinese mothers were recruited from an integrated young mother supportive program in Hong Kong between January and June 2015. Eligible mothers were asked to complete a questionnaire on their sociodemographic characteristics and history of risky behavior as well as their children's behaviors. Multiple regression analyses were conducted to explore the association between maternal risky behaviors and their children's behaviors.
Results:
Among 201 respondents, there were 187 (93.0%) ex-drinkers, 136 (67.7%) ex-smokers, and 83 (41.3%) ex-addicts. Compared to the reference group, children of mothers with drug use behaviors were more likely to have abnormal SDQ total difficulties scores (odds ratio 2.60,

Introduction: Current literature reports varied significance
of ulnar styloid fractures (USF) associated with distal radius
fractures. Our study assesses the role of ulnar styloid
fractures and fragment size in surgically managed distal
radius fractures.
Materials and methods: We reviewed patients who
underwent surgical fixation of distal radius fractures between
January 2004 to June 2006. Patients were divided into those
with (Group 1) and without (Group 0) USFs. Post-operative
radiographic parameters, clinical outcomes and overall wrist
function were analysed. Outcomes included ulnar-sided
wrist pain, extensor carpi ulnaris (ECU) tendinitis, triangular
fibrocartilage complex (TFCC) grind test, distal radioulnar
joint (DRUJ) instability and pain. Overall wrist function was
assessed with range of motion and Disabilities of the Arm,
Shoulder and Hand (DASH) score.
Results: Our study cohort included 31 males and 23 females,
and 38.9% of these patients had concomitant USFs. There
was no difference in terms of demographic data and fracture
configuration between groups. Radiographic parameters
were similar, except for palmar tilt, which was significantly
higher in Group 1 (4.6º vs 9.4º, p=0.047). At 24 months,
there were no differences in clinical outcomes and overall
wrist function. A sub-group analysis showed that mean USF
fragment size was larger in patients with a positive TFCC
grind test (3.9mm vs 7.3mm, p=0.033).
Conclusion: The presence of USFs in surgically managed
distal radius fractures does not compromise clinical and
functional outcome. Similarly, the size of USFs does not
impact clinical and functional outcome but is associated with
the presence of a positive TFCC grind test.
