Introduction: A vegetarian diet is generally considered as healthy for preventing metabolic-related diseases. There is lack of studies in Malaysia comparing the nutritional status of vegetarians and non-vegetarians. This cross-sectional study aims to compare body weight status, dietary intake and blood pressure level between these two groups. Methods: A total of 131 vegetarians and 135 non-vegetarians were recruited using convenience sampling from a Buddhist organisation in Kuala Lumpur. Body weight, height, waist circumference, percentage of body fat, and blood pressure measurements were taken, while dietary intake was assessed using a 2-day 24-hour dietary recall. Results: More vegetarians were underweight than non-vegetarians (31.3% vs 15.6%), while prevalence of overweight and obesity was higher among the non-vegetarians (23.7% vs 9.9%). A higher proportion of nonvegetarians (34.1%) had an unhealthy range of body fat percentage and significantly higher risk of abdominal obesity (24.4%) than the vegetarians (19.1% body fat; 13.7% abdominal obesity). Mean intakes for protein and fat were significantly lower among the vegetarians, while no significant differences were observed in the mean intake for energy and carbohydrate. Vegetarians had significantly higher intakes of vitamins C, D and E, calcium, potassium and folate, while vitamin B12 intake was significantly higher in the non-vegetarians. More non-vegetarians presented with unhealthy blood pressure status. Conclusion: Vegetarians in this study generally showed healthier dietary intake and lower body fatness than the non-vegetarians. Studies are suggested to be undertaken on a bigger sample size of vegetarians to confirm these findings.
Home health monitoring devices are consumer-grade devices that help to monitor the health of individuals at home. These devices are usually low-cost and easily procurable, and they can be operated by patients or their caretakers with minimal training. However, improper usage of these devices may provide erroneous results, which can lead to an unnecessary hospital visit or teleconsultation. In this article, we discuss the basic technology and proper usage of some of these devices, namely automatic blood pressure monitors, blood glucose monitors, body fat monitors, pulse oximeters, electrocardiographs, digital thermometers, and infrared thermometers. This brief document intends to help primary health care professionals and their patients use these devices.
Dioxins are a most toxic compound ever studied by human until today. Their significant health effects involved all ranges of age, including infants due to exposure to contaminated breast milk. The objective of the study was to appraise the status of dioxin contamination in breast milk among postnatal mothers live in urban and suburban areas in Klang Valley. It was conducted as a cross sectional study involving 101 postnatal mothers who came for their infant second hepatitis B vaccination. The samples were analysed using High Resolution Gas Chromatography (HRGC) following the USEPA Method 8290. About 70.3% of the samples were found detected with dioxin congeners. More suburban mothers have positive breast milk dioxins compared to urban mothers, 100.0% and 67.0% respectively. Significant associated factors include high fat daily intake (p=0.013), high milk daily intake (p= 0.044), high meat daily intake (p=0.001), body mass index more than 30 kg/m2 (p=0.005), and body fat % of more than 26% (p=0.046). In conclusion, amount daily intake of fat diet, meat, milk, body mass index and body fat are significant associated factors for the present of dioxins in breast milk among postnatal mothers in Klang Valley. More suburban mothers contain dioxins in their breast milk, which poses higher risk of health problems among their infants. A comprehensive study need to be conducted and regular followup need to be established in monitoring the future severity of maternal breast milk contamination to ensure the health of the next generations.
Complementary Alternative Medicine (CAM) is broadly used as an adjunct treatment for patients to treat various kinds of disease, prevent disease and to sustain and enhance quality of life of the users. The study is aimed to investigate the association between CAM uses, Health-Related Quality of Life (HRQoL) and anthropometric indices among workers or staffs in Universiti Sultan Zainal Abidin (UniSZA) Gong Badak Campus, Kuala Terengganu. A total of 300 subjects participated in this study and completed the malay version of modified HRQol (SF-12) questionnaires. Anthropometric measurements among the subjects were done. Independent t-test, One-way ANOVA and Pearson correlation were used to test the association and the hypotheses. The prevalence of CAM users was 37.3%. The results showed that bodily pain score domain was significantly higher among non-CAM users. Overall, male had higher Mental Health Composite Score (MCS) score than female. Physical Health Composite Score (PCS) was only correlated negatively with BMI among non-CAM users but negative correlated with body fat percentage in both CAM and non-CAM users. As conclusion, HRQoL had significant negative correlation with body fat percentage among CAM users. No association was found between CAM use and HRQoL scores.

As conclusion, HRQoL had significant negative correlation with body fat percentage among CAM users. No association was found between CAM use and HRQoL scores.
Thirty-six adult male SD rats, weighing 200-250 g were used in this study. Dietary obesity was induced by feeding high-fat diet (HFD) for 12 weeks. One group of animal (n=6) served as normal control which received normal diet from the beginning to the end of the study. The other 30 male obese animals induced by HFD were randomly divided into five experimental groups: The group which received high-fat diet considered as a negative control and the other four groups were treated with saffron extract and crocin in low and high dosages of 40 and 80 mg/kg for 8 weeks. At the end of treatment period, kidney and pancreas were removed and stained with hematoxylin and eosin (H&E). There were significant histopathological changes, such as tubular degenerative, vascular congestion and interstitial inflammation in the kidney and extensive pancreatic adipose tissue infiltration in high-fat diet rats group when compared with normal control. The results showed less significant histopathological changes of the kidney and also moderate pancreatic adipose tissue infiltration in the groups treated with crocin. Interestingly saffron extract dose-independently displayed significant renal protective effect while a significant decrease in pancreatic adipose tissue infiltration was observed in obese rat treated with high dose of saffron extract (80 mg/kg). From these results, it can be concluded that consumption of saffron extract reduced the untoward effects of high-fat diet in kidney and pancreas of high-fat diet induced obese rats.
Introduction: There is an emergent increase of ultra-processed food consumption in developing countries including Malaysia which carries a likelihood towards the increase of obesity. However, few studies have been done in relating between ultra-processed consumption and obesity, especially in Malaysia. Therefore, this study aims to determine the consumption of ultra-processed foods and its relationship with BMI and body fat percentage among university committee in Kuala Nerus, Terengganu. Methods: A cross-sectional study was performed among 167 individuals aged 18 to 59 years old in Kuala Nerus. Data were collected using a researcher-administered questionnaire which consisted of three different sections: socio-demographic profile, two days 24-hour dietary recall, and nutritional status assessment on BMI and body fat percentage. Consumption of ultra-processed foods were determined by classifying two days 24-hour dietary recall based on ultra-processed food classification. Data were analyzed using SPSS version 21.0 with p
Introduction: Short-term fasting may influence intraocular pressure (IOP) due to alteration of fluid (total body water;
TBW, and water intake) and fat (total body fat; TBF). This study aimed: i) to compare IOP values within and between,
fasting and non-fasting periods; and ii) to assess the association between IOP and, TBW and TBF. Methods: Thirty
healthy participants aged 21.8±1.1 years were assessed on two different periods (fasting vs. non-fasting). During each
period, the IOP, TBW and TBF values were assessed for four times (morning, afternoon, evening, late-evening). The
IOP was measured using AccuPen® tonopen, while TBW and TBF were assessed by using a Tanita body composition
analyser. Results: During fasting, the IOP value in the afternoon (14.53±2.33 mmHg) was significantly higher than in
the evening (12.43±2.73 mmHg, p=0.009) and late-evening (12.60±2.44 mmHg, p=0.003). No significant difference
in IOP was observed during non-fasting period. The mean of IOP in the evening was significantly lower during fasting
compared to non-fasting (12.43±2.73 mmHg vs 13.75±2.53 mmHg, p=0.044). The IOP and TBW were negatively
correlated (r=-0.268; p=0.011) during non-fasting and showed no association during fasting period. There was no
significant correlation between IOP and TBF during both fasting and non-fasting periods. Conclusion: IOP reduction
during short-term fasting, together with the no association with TBF and TBW suggested that IOP is an independent
factor that reduces during fasting in healthy population.
This article aimed to review the available anthropometry measurements used in the assessment of nutritional sta- tus among Cerebral Palsy (CP) children. Searched journals were from Medline, PubMed and Ovid published from 2015 to 2018. The search identified 443 articles, and eight studies met the criteria. Anthropometric measurements included weight, height, recumbent length, knee height, tibia length, Dual-energy X-ray absorptiometry (DXA), Bio- electrical impedance (BIA), Mid arm circumference (MUAC) subscapular skinfold (SFT), Triceps skinfold (TSF) and prediction equations. Body fat composition can be obtained by DXA, BIA, skinfold measurement, and also prediction equation. The predictive equation is the most reported method to determine nutritional status among CP. This review found that TSF and SFT are more accurate to determine body fat percentage when using together with the predictive equation. Besides, predictive equations using segmental length are reliable in estimating the height and can be used to evaluate the nutritional status using the specific CP growth chart.
Vitamin D plays an important role in maintaining the physical health as well as the performance of athletes. This cross-sectional analytical study was conducted to determine vitamin D intake, sun exposure and skin types of both indoor and outdoor Malaysian athletes in the National Sports Institute, Bukit Jalil. Method: A total of 28 indoor (badminton, shooting, wushu and fencing) and 36 outdoor (athletics, football and hockey) athletes were recruited for this study. The dietary vitamin D intake was estimated using Vitamin D-specific Food Frequency Questionnaire (FFQ). The Sun Exposure Index (SEI) was calculated from Seven-day Sun Exposure Record while the skin types of athletes were determined using Fitzpatrick Skin Typing Questionnaire. Results: The mean age of the athletes was 21.02±4.11 years and their mean Body Mass Index (BMI) was 22.20±2.22 kg/m2. The mean body fat percentage of outdoor athletes was significantly lower than indoor athletes (p
Lipoma arborescens is a non-neoplastic, reactive condition due to chronic synovial inflammation and irritation, characterized by frond-like or villous proliferation of mature adipose tissue covered by hyperplastic synovium. The knee is the most commonly affected site particularly the suprapatellar pouch. We report a case of lipoma arborescens affecting the right knee of an elderly Chinese gentleman associated with bilateral knee and hand osteoarthritis. He presented with progressive worsening of right knee swelling and pain. Partial synovectomy of the right knee was performed and no lesion recurrence was noted at one year post-operation. The clinical and imaging findings, pathological features, together with differential diagnoses were discussed.
More than 100 attendees from Australia, Austria, Belgium, Canada, China, Germany, Hong Kong, Indonesia, Japan, Malaysia, the Netherlands, the Philippines, Republic of Korea, Singapore, Sweden, Switzerland, the United Kingdom, and the United States convened in Singapore for the 2019 ISMRM-sponsored workshop on MRI of Obesity and Metabolic Disorders. The scientific program brought together a multidisciplinary group of researchers, trainees, and clinicians and included sessions in diabetes and insulin resistance; an update on recent advances in water-fat MRI acquisition and reconstruction methods; with applications in skeletal muscle, bone marrow, and adipose tissue quantification; a summary of recent findings in brown adipose tissue; new developments in imaging fat in the fetus, placenta, and neonates; the utility of liver elastography in obesity studies; and the emerging role of radiomics in population-based "big data" studies. The workshop featured keynote presentations on nutrition, epidemiology, genetics, and exercise physiology. Forty-four proffered scientific abstracts were also presented, covering the topics of brown adipose tissue, quantitative liver analysis from multiparametric data, disease prevalence and population health, technical and methodological developments in data acquisition and reconstruction, newfound applications of machine learning and neural networks, standardization of proton density fat fraction measurements, and X-nuclei applications. The purpose of this article is to summarize the scientific highlights from the workshop and identify future directions of work.
The metabolic syndrome (MetS) is a cluster of metabolic abnormalities comprising visceral obesity, dyslipidaemia and insulin resistance (IR). With the onset of IR, the expression of lipoprotein lipase (LPL), a key regulator of lipoprotein metabolism, is reduced. Increased activation of glucocorticoid receptors results in MetS symptoms and is thus speculated to have a role in the pathophysiology of the MetS. Glycyrrhizic acid (GA), the bioactive constituent of licorice roots (Glycyrrhiza glabra) inhibits 11beta-hydroxysteroid dehydrogenase type 1 that catalyzes the activation of glucocorticoids. Thus, oral administration of GA is postulated to ameliorate the MetS.
Biological therapies are new additions to breast cancer treatment. Among biological compounds, beta-carotene has been reported to have immune modulatory effects, in particular, enhancement of natural killer cell activity and tumor necrosis factor-alpha production by macrophages. The objective of this study was to investigate the effect of palm carotene supplementation on the tumorigenicity of MCF-7 human breast cancer cells injected into athymic nude mice and to explore the mechanism by which palm carotenes suppress tumorigenesis. Forty-eight 4-wk-old mice were injected with 1 x 10(6) MCF-7 cells into their mammary fat pad. The experimental group was supplemented with palm carotene whereas the control group was not. Significant differences were observed in tumor incidence (P< 0.001) and tumor surface area and metastasis to lung (P< 0.005) between the two groups. Natural killer (NK) cells and B-lymphocytes in the peripheral blood of carotene-supplemented mice were significantly increased (P < 0.05 and P < 0.001, respectively) compared with controls. These results suggest that palm oil carotene is able to modulate the immune system by increasing peripheral blood NK cells and B-lymphocytes and suppress the growth of MCF-7 human breast cancer cells.
Osteoradionecrosis (ORN) is a well-recognized, debilitating complication of radiotherapy for patients with head and neck cancer. There is no universally accepted treatment for ORN of the jawbones. We report on a case of refractory mandibular ORN treated by sequestrectomy of mandible and autogenous transplantation of fat graft combined with platelet-rich fibrin (PRF). Improved perfusion was observed using the laser Doppler flowmetry. This case highlights the use of autogenous free fat graft and PRF as an adjunct therapy to sequestrectomy in the management of ORN.
This quasi experimental study is aimed to determine the effect of 8 weeks physical exercise training program among 219 obese an overweight National Service Training Program (NSTP). It is a purposive sampling and divide to experimental group (n = 110) and control group (n = 109). Body fat (BFP) measured using Omron Karada Scan HBF 375 with Height Scale. The experimental group underwent 8 weeks physical exercise program using the NSTP wellness module. The module contains 18 low intensity training, 40 moderate intensity training and 14 high intensity training with 8 psychological sessions. Analysis showed a significant difference between pre-test and post-test after 8 weeks in experimental group. There was a greater decrease BFP (-1.44%) and weight (-2.03%). The control group showed slightly increase in BFP (+2.97%) but decrease weight (-0.28%). This means the intervention program very effective and manage to reduce the BFP and weight among 18 years old obese and overweight NSTP in Malaysia.
In the field of cell-based therapy and regenerative medicine, clinical application is the ultimate goal. However, one major concern is: does in vitro manipulation during culture expansion increases tumourigenicity risk on the prepared cells? Therefore, the aim of this study was to investigate the effect of long-term in vitro expansion on human adipose-derived stem cells (ASCs). The ASCs were harvested from lipo-aspirate samples and cultured until passage 20 (P20), using standard culture procedures. ASCs at P5, P10, P15 and P20 were analysed for morphological changes, DNA damage (Comet assay), tumour suppressor gene expression level (quantitative PCR), p53 mutation, telomerase activity, telomere length determination and in vivo tumourigenicity test. Our data showed that ASCs lost their fibroblastic feature in long-term culture. The population doubling time of ASCs increased with long-term culture especially at P15 and P20. There was an increase in DNA damage at later passages (P15 and P20). No significant changes were observed in both p53 and p21 genes expression throughout the long-term culture. There was also no p53 mutation detected and no significant changes were recorded in the relative telomerase activity (RTA) and mean telomere length (TRF) in ASCs at all passages. In vivo implantation of ASCs at P15 and P20 into the nude mice did not result in tumour formation after 4 months. The data showed that ASCs have low risk of tumourigenicity up to P20, with a total population doubling of 42 times. This indicates that adipose tissue should be a safe source of stem cells for cell-based therapy.
The discovery of mesenchymal stem cells (MSCs) from a myriad of tissues has triggered the initiative of establishing tailor-made stem cells for disease-specific therapy. Nevertheless, lack of understanding on the inherent differential propensities of these cells may restrict their clinical outcome. Therefore, a comprehensive study was done to compare the proliferation, differentiation, expression of cell surface markers and gene profiling of stem cells isolated from different sources, viz. bone marrow, Wharton's jelly, adipose tissue and dental pulp. We found that although all MSCs were phenotypically similar to each other, Wharton's jelly (WJ) MSCs and dental pulp stem cells (DPSCs) were highly proliferative as compared to bone marrow (BM) MSCs and adipose tissue (AD) MSCs. Moreover, indistinguishable cell surface characteristics and differentiation capacity were confirmed to be similar among all cell types. Based on gene expression profiling, we postulate that BM-MSCs constitutively expressed genes related to inflammation and immunodulation, whereas genes implicated in tissue development were highly expressed in AD-MSCs. Furthermore, the transcriptome profiling of WJ-MSCs and DPSCs revealed an inherent bias towards the neuro-ectoderm lineage. Based on our findings, we believe that there is no unique master mesenchymal stem cell that is appropriate to treat all target diseases. More precisely, MSCs from different sources exhibit distinct and unique gene expression signatures that make them competent to give rise to specific lineages rather than others. Therefore, stem cells should be subjected to rigorous characterization and utmost vigilance needs to be adopted in order to choose the best cellular source for a particular disease.
Epidemiological evidence shows that diabetic patients are susceptible to high temperature weather, and brown adipose tissue (BAT) activity is closely related to type 2 diabetes (T2DM). Activation of BAT under cold stress helps improve T2DM. However, the impact of high temperature on the activity of BAT is still unclear. The study aimed to investigate the impact of heat stress on glucose and lipid metabolism in T2DM mice by influencing BAT activity. High-fat feeding and injecting streptozotocin (STZ) induced model of T2DM mice. All mice were randomly divided into three groups: a normal(N) group, a diabetes (DM) group and a heat stress diabetes (DMHS) group. The DMHS group received heat stress intervention for 3 days. Fasting blood glucose, fasting serum insulin and blood lipids were measured in all three groups. The activity of BAT was assessed by using quantitative real-time PCR (qRT-PCR), electron microscopy, and PET CT. Furthermore, the UHPLC-Q-TOF MS technique was employed to perform metabolomics analysis of BAT on both DM group and DMHS group. The results of this study indicated that heat stress aggravated the dysregulation of glucose and lipid metabolism, exacerbated mitochondrial dysfunction in BAT and reduced the activity of BAT in T2DM mice. This may be related to the abnormal accumulation of branched-chain amino acids (BCAAs) in the mitochondria of BAT.
