Characteristics of dietary intakes including NOVA foods among pre-adolescents living in urban Kuala Lumpur – Findings from the PREBONE-Kids study

@#Introduction: Evidence showed considerable variability of health risk factors within different socioeconomic groups. This study aimed to characterise dietary intakes by total household income among a sample of Malaysian pre-adolescents in urban Kuala Lumpur. Methods: Baseline data of 243 healthy, pre-adolescent children between 9 and 11 years old including socio-demographic background (gender, ethnicity, and total household monthly income), anthropometry (body weight and height), and 7-day diet histories were collected. Secondary analysis was performed on dietary intakes to quantify food groups based on the Malaysian Dietary Guidelines and NOVA classification systems besides nutrients. Differences and associations between total monthly household income categories with anthropometry and dietary intakes were tested using independent t-test/Mann-Whitney U (depending on normality) and chi-square tests, respectively. Results: Most children in this study population had dietary intakes below the recommended serving sizes for five food groups, except meat/poultry (195.2±107.2%) and fish (110.1±106.3%) and consumed about 32% of energy from ultra-processed foods (NOVA food group 4). While there was no difference in dietary intake between the bottom 40% with the middle 40% and high 20% household income groups, the percentage of energy contributed by NOVA food group 4 (processed fats/oils, condiments, and sauces) was higher in the bottom 40% households (p=0.024). Conclusion: Most pre-adolescent children in this study, regardless of household income, did not meet dietary recommendations and ate diets comprised of less nutritious foods. Comprehensive approaches that aim to improve dietary patterns and reduce the risk of diet-related chronic diseases are warranted.

Barcelona Clinic Liver Cancer and Hong Kong Liver Cancer staging systems for prediction of survival among Hepatocellular Carcinoma patients

@#Introduction: We aimed to compare the Barcelona Clinic Liver Cancer (BCLC) and Hong Kong Liver Cancer (HKLC) staging systems. Materials and Methods: This is a retrospective study on patients with newly diagnosed hepatocellular carcinoma (HCC) at the University Malaya Medical Centre between 2011 and 2014. Survival times were analysed using the KaplanMeier procedure and comparison between groups was done using the log rank test. Results: The data of 190 patients was analysed. Chronic hepatitis B was the most common aetiology for HCC (43.7%), but a large proportion was cryptogenic or non-alcoholic steatohepatitis-related (41.6%). Only 11.1% were diagnosed early (BCLC Stage 0-A) while majority were diagnosed at an intermediate stage (BCLC Stage B, 53.7%). The median survival rate was significantly different between the different groups when either of the staging systems was used (p<0.05 for all comparisons). However, the two staging systems lacked agreement (weighted kappa 0.519, 95%CI: 0.449, 0.589) with significant difference in median survival rates between BCLC Stage A and HKLC Stage 2, and between BCLC Stage C and HKLC Stage 4. Conclusion: Both staging systems were able to stratify patients according to survival, but they only had moderate agreement with significant differences observed in two groups of the staging systems.

Psychometric Properties of the Malay Version of the Dutch Eating Behaviour Questionnaire (DEBQ) in a Sample of Malaysian Adults Attending a Health Care Facility

Objective: This study aims to investigate the psychometric properties of the Malay version of the Dutch Eating Behaviour Questionnaire (DEBQ) among Malaysian adults. Method: The Malay version of the DEBQ instrument was administered to 398 outpatients (269 women and 129 men) at the University of Malaya Medical Centre (UMMC). Confirmatory Factor Analysis (CFA) was conducted to study the construct validity of the instrument. Composite reliability coefficient, Raykov's rho, was used to determine the internal consistency. Results: The proposed three-factor structure for the DEBQ instrument was appropriate, although three items (Items 21, 14 and 27) showed problematic loadings with inappropriate model fit and were removed. The modified version had an appropriate model fit χ2/df = 2.129, TLI = 0.908, CFI = 0.918, RMSEA = 0.053 (90%CI = 0.048–0.058), close-fit P-value = 0.136 and satisfactory internal consistency of 0.914 for emotional eating scale, 0.819 for external eating scale and 0.856 for restrained eating scale. Discussion: The Malay version of the DEBQ is a valid instrument to study eating behaviour traits among Malaysian adults. Further research is warranted to determine if Items 14 and 27 are appropriate for the Malaysian population.

Clinical investigation of the protective effects of palm vitamin E tocotrienols on brain white matter.

BACKGROUND AND PURPOSE: Previous cell-based and animal studies showed mixed tocotrienols are neuroprotective, but the effect is yet to be proven in humans. Thus, the present study aimed to evaluate the protective activity of mixed tocotrienols in humans with white matter lesions (WMLs). WMLs are regarded as manifestations of cerebral small vessel disease, reflecting varying degrees of neurodegeneration and tissue damage with potential as a surrogate end point in clinical trials. METHODS: A total of 121 volunteers aged ≥35 years with cardiovascular risk factors and MRI-confirmed WMLs were randomized to receive 200 mg mixed tocotrienols or placebo twice a day for 2 years. The WML volumes were measured from MRI images taken at baseline, 1 year, and 2 years using a validated software and were compared. Fasting blood samples were collected for full blood chemistry investigation. RESULTS: According to per-protocol (88 volunteers) and intention-to-treat (121 volunteers) analyses, the mean WML volume of the placebo group increased after 2 years, whereas that of the tocotrienol-supplemented group remained essentially unchanged. The mean WML volume change between the 2 groups was not significantly different (P=0.150) at the end of 1 year but was significant at the end of 2 years for both per-protocol and intention-to-treat analyses (P=0.019 and P=0.018). No significant difference was observed in the blood chemistry parameters between the 2 groups. CONCLUSIONS: Mixed tocotrienols were found to attenuate the progression of WMLs.

Psychometric properties and validation of the Satisfaction with Life Scale in psychiatric and medical outpatients in Malaysia.

The present study evaluated the psychometric properties and factor structure of the Satisfaction With Life Scale (SWLS) in a sample of clinical outpatients in Malaysia. The SWLS is a measure designed to assess subjective life satisfaction. Four hundred eighty-three participants (283 with psychiatric illnesses and 200 with other medical illnesses) completed the SWLS and other self-report instruments. Results of the EFA and CFA supported the fit for the one-factor model as the best-fitting model. The internal consistency of the SWLS (α=0.86) was found to be high. Correlational analyses showed that SWLS had adequate concurrent validity. Scores on SWLS, which differentiated psychiatric patients and medical patients, supported criterion validity. The logistic regression analyses showed good discriminative validity of SWLS. The SWLS is a reliable and valid instrument to measure the satisfaction with life among psychiatry and clinical outpatients in Malaysia.

The temerloh hospital cataract complications study:factors associated with, types and outcomes of cataract surgery complications / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To study the prevalence of complications of cataract surgery and any association between the occurrence of complications and experience of surgeon, type of surgery, type of anaesthesia and visual outcome.METHODS: This was a retrospective study of patients who underwent cataract surgery over a period of two years in a district hospital in Malaysia. The demographic details of patients, type of surgery done, as well as type of anaesthesia used and experience of the surgeon were noted. The types of intraoperative and postoperative complications were recorded. The final best corrected visual outcome was recorded. RESULTS:Complications occurred in 11. 1% of the total 1007 patients operated. Posterior capsule rupture (3. 6%) was the most common complication. The experience of the surgeon and the type of anaesthesia used did not affect complications during surgery. Intracapsular cataract extraction ( ICCE ) and phacoemulsification converted to extracapsular cataract extraction ( ECCE ) were significantly associated with more complications ( P CONCLUSION: The occurrence of complications during cataract surgery significantly affected the visual outcome. The type of surgery done was associated by the occurrence of complications. However, the experience of the surgeon and the type of anaesthesia used did not affect the occurrence of complications. We recommend that particular attention be given to ICCE and phacoemulsification converted to ECCE to minimise the complications and thereby reducing the chances of poor vision postoperatively.

Preliminary study of an exercise programme for reducing fatigue and improving sleep among long-term haemodialysis patients

<p><b>INTRODUCTION</b>Fatigue and quality of sleep are the main factors that contribute to a poor quality of life among patients on long-term haemodialysis. Studies have also emphasised the importance of exercise for improving the wellbeing of dialysis patients. This study aimed to determine the effectiveness of a predialysis low-to-moderate-intensity exercise programme for reducing fatigue and improving sleep disorders among long-term haemodialysis patients.</p><p><b>METHODS</b>In this quasi-experimental study, an exercise programme was conducted three times a week for 12 weeks before long-term haemodialysis patients underwent dialysis at two centres. The patients were categorised into either the exercise group (n = 28) or control group (n = 27). The latter was asked to maintain their current lifestyles. Assessments of fatigue and sleep disorder levels were performed for both groups using self-reported questionnaires at baseline and after intervention. The patients' perception of the exercise programme was also determined using self-reported questionnaires.</p><p><b>RESULTS</b>Paired sample t-test indicated improvements in fatigue level in the exercise group (mean fatigue score: post-treatment 40.5 ± 7.9 vs. pre-treatment 30.0 ± 10.9). Improvements in sleep disorders were also observed in the exercise group (mean score: post-treatment 7.6 ± 3.3 vs. pre-treatment 10.1 ± 3.8). However, sleep quality deteriorated in the control group (mean score: post-treatment 10.7 ± 2.9 vs. pre-treatment 9.3 ± 2.9).</p><p><b>CONCLUSION</b>Simple low-to-moderate-intensity exercise is effective for improving fatigue, sleep disorders and the overall quality of life among haemodialysis patients.</p>

Bile salt deconjugation and cholesterol removal from media by Lactobacillus strains used as probiotics in chickens.

BACKGROUND: Bile salt deconjugation by Lactobacillus strains is often closely linked to bile tolerance and survival of the strains in the gut and lowering of cholesterol in the host. The present study investigated the deconjugation of bile salts and removal of cholesterol by 12 Lactobacillus strains in vitro. The 12 strains were previously isolated from the gastrointestinal tract of chickens. RESULTS: The 12 Lactobacillus strains could deconjugate sodium glycocholate (GCA, 16.87-100%) and sodium taurocholate (TCA, 1.69-57.43%) bile salts to varying degrees, with all strains except L. salivarius I 24 having a higher affinity for GCA. The 12 Lactobacillus strains also showed significant (P < 0.05) differences in their ability to remove cholesterol from the growth medium (26.74-85.41%). Significant (P < 0.05) correlations were observed between cholesterol removal and deconjugation of TCA (r = 0.83) among the L. reuteri strains (C1, C10 and C16) and between cholesterol removal and deconjugation of TCA (r = 0.38) and GCA (r = 0.70) among the L. brevis strains (I 12, I 23, I 25, I 211 and I 218). In contrast, although L. gallinarum I 16 and I 26 and L. panis C 17 showed high deconjugating activity, there was no correlation between cholesterol removal and deconjugation of bile salts in these strains. CONCLUSION: The results showed that the 12 Lactobacillus strains were able to deconjugate bile salts and remove cholesterol in vitro, but not all strains with high deconjugating activity removed cholesterol effectively.

Calcium Intake, Vitamin D and Bone Health Status of Post-menopausal Chinese Women in Kuala Lumpur

Bone health status was investigated in 178 free-living Chinese post-menopausal women in Kuala Lumpur. Body mass index (BMI), body composition (using whole body DXA), calcium intake and serum 25-OH vitamin D status were measured along with biochemical markers of bone turnover, that is, pro-collagen Type 1 N-terminal peptide (P1NP), osteocalcin (OC) and C-telopeptide ß cross link of Type 1 collagen (CTX- β). Bone mineral density (BMD) was measured using DXA (Hologic, USA) at the lumbar spine, femoral neck and total hip. Results showed that osteopenia was present in 50% of the subjects at the spine and 57.9% at the femoral neck. Osteoporosis was diagnosed in 10% of the subjects at both the femoral neck and spine. A total of 29.3% of the subjects had high levels of CTX- ß. Mean serum level of 25-OH vitamin D was 60.4+15.6 nmol/L and 50.6% of the subjects had hypovitaminosis D (defined as <50 nmol/l). Mean total calcium intake of the subjects was 497 + 233 mg, of which only 14% met the RNI for calcium with the additional intake of calcium supplements. Body fat was also significantly correlated (r=0.181, p<0.05) with BMD at the spine but not BMD at the femoral neck. Lean body mass was positively correlated with BMD at the spine (r=0.289, p<0.001) and femoral neck (r=0.295, p<0.001). CTX-β was negatively correlated with BMD at the spine (r= -0.235, p<0.001), whereas P1NP (r=-0.215, p<0.001) and osteocalcin (r=-0.265, p<0.001) were both negatively correlated with BMD at the femoral neck. Generally, the study found that women with osteopenia had higher levels of bone turnover markers, less lean body mass and lower calcium intake than women with normal BMD. In conclusion, this study demonstrated that the majority of free living Chinese post-menopausal women in Kuala Lumpur have low calcium intake, low 25-OH vitamin D status and low bone mass and elevated biochemical markers of bone turnover.
