Heart failure-associated morbidity and mortality is largely attributable to extensive and unregulated cardiac remodelling. Roselle (Hibiscus sabdariffa) calyces are enriched with natural polyphenols known for antioxidant and anti-hypertensive effects, yet its effects on early cardiac remodelling in post myocardial infarction (MI) setting are still unclear. Thus, the aim of this study was to investigate the actions of roselle extract on cardiac remodelling in rat model of MI. Male Wistar rats (200-300 g) were randomly allotted into three groups: Control, MI, and MI + Roselle. MI was induced with isoprenaline (ISO) (85 mg/kg, s.c) for two consecutive days followed by roselle treatment (100 mg/kg, orally) for 7 days. Isoprenaline administration showed changes in heart weight to body weight (HW/BW) ratio. MI was especially evident by the elevated cardiac injury marker, troponin-T, and histological observation. Upregulation of plasma levels and cardiac gene expression levels of inflammatory cytokines such as interleukin (IL)-6 and IL-10 was seen in MI rats. A relatively high percentage of fibrosis was observed in rat heart tissues with over-expression of collagen (Col)-1 and Col-3 genes following isoprenaline-induced MI. On top of that, cardiomyocyte areas were larger in heart tissues of MI rats with upregulation of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) gene expression, indicating cardiac hypertrophy. Interestingly, roselle supplementation attenuated elevation of plasma troponin-T, IL-6, IL10, and gene expression level of IL-10. Furthermore, reduction of cardiac fibrosis and hypertrophy were observed. In conclusion, roselle treatment was able to limit early cardiac remodelling in MI rat model by alleviating inflammation, fibrosis, and hypertrophy; hence, the potential application of roselle in early adjunctive treatment to prevent heart failure.

Fulltext The protective effect of aqueous extracts of roselle (Hibiscus sabdariffa L. UKMR-2) against red blood cell membrane oxidative stress in rats with streptozotocin-induced diabetes

Mohamed J, Shing SW, Idris MH, Budin SB, Zainalabidin S

Clinics (Sao Paulo), 2013 Oct;68(10):1358-63.
PMID: 24212844 DOI: 10.6061/clinics/2013(10)11

OBJECTIVES: The aim of this study was to investigate the protective effects of aqueous extracts of roselle (Hibiscus sabdariffa L. UKMR-2) against red blood cell (RBC) membrane oxidative stress in rats with streptozotocin-induced diabetes.
METHODS: Forty male Sprague-Dawley rats weighing 230-250 g were randomly divided into four groups (n = 10 rats each): control group (N), roselle-treated control group, diabetic group, and roselle-treated diabetic group. Roselle was administered by force-feeding with aqueous extracts of roselle (100 mg/kg body weight) for 28 days.
RESULTS: The results demonstrated that the malondialdehyde levels of the red blood cell membranes in the diabetic group were significantly higher than the levels in the roselle-treated control and roselle-treated diabetic groups. The protein carbonyl level was significantly higher in the roselle-treated diabetic group than in the roselle-treated control group but lower than that in the diabetic group. A significant increase in the red blood cell membrane superoxide dismutase enzyme was found in roselle-treated diabetic rats compared with roselle-treated control rats and diabetic rats. The total protein level of the red blood cell membrane, osmotic fragility, and red blood cell morphology were maintained.
CONCLUSION: The present study demonstrates that aqueous extracts of roselle possess a protective effect against red blood cell membrane oxidative stress in rats with streptozotocin-induced diabetes. These data suggest that roselle can be used as a natural antioxidative supplement in the prevention of oxidative damage in diabetic patients.

Hypoglycaemic and antihyperglycemic activity of oil palm Elaeis guineensis fruit extract on normal and Streptozotocininduced
diabetic rats was studied. The oil palm fruit extract (OPF) were administered orally at different concentrations (100,
200 and 500 mg kg-1 b.w.) in fasting and post-prandial rats. Hypoglycaemia was not observed in the group of normal rats
treated with OPF. In fasting rats, OPF (500 mg kg-1 b.w.) has caused the blood glucose level (BGL) to reduce significantly.
For post-prandial diabetic rats, the antihyperglycemic activity was observed after OPF treatment at concentrations 200
and 500 mg kg-1. Chronic OPF treatments (for 28 days) had increased the diabetic rat’s body weight and reduced BGL as
well as improved plasma insulin secretion. The result of this study suggests E. guineensis palm fruit extract show evidence
of antihyperglycemic properties from the reduction of the BGL in diabetic rats.

Relationship of scrotal circumference to age, body weight and onset of spermatogenesis in goats

Bongso TA, Jainudeen MR, Zahrah AS

Theriogenology, 1982 Nov;18(5):513-24.
PMID: 16725772

Scrotal circumference (SC) and body weight (BW) measurements were obtained from 122 crossbred (SaanenxLoca; JumnaparixLocal) bucks, ranging in age from 3 to 28 months. Spermatogenesis and semeniferous tubule diameters were studied from testicular biopsies in 24 bucks. The results showed that SC increased curvilinearly and was significantly correlated with age (P<0.05). Scrotal circumference correlated more significantly with BW (P<0.001). Spermatogenesis was completed at 6-7 months with a sudden increase in tubular diameter at the same time. Since SC is an indirect measurement of testicular size, a marked increase in testicular size indicated the onset of active spermatogenesis and, hence, the possibility of using bucks for breeding at an earlier age than normally recommended. Further, SC norms obtained in this study may become useful in the evaluation of bucks for breeding soundness.

Recent evidence has exhibited dietary influence on the manifestation of depressive-like behaviour induced by stressor tasks. The present study examined the effects of Tualang honey supplement administered with the goal of preventing or attenuating the occurrence of depressive-like behaviour in male rats subjected to noise stress. Forty-eight adult male rats were randomly divided into the following groups: i) nonstressed with placebo, ii) nonstressed with honey, iii) stressed with placebo, and iv) stressed with honey. Tualang honey (200 mg/kg body weight) was administered for 28 days. Stressed rats were subjected to loud noise 100 dB(A) 4 hours daily for 14 days. Forced swimming test was performed to evaluate depressive-like behaviour. Stressed control rats displayed significant increase in depressive-like behaviour, serum adrenocorticotropic hormone (ACTH), corticosterone, and brain oxidative stress markers levels, with significant decrease in antioxidant enzymes activities and total antioxidant status. Honey supplementation successfully counteracted the stress effects whereby the honey treated rats exhibited significant decrease in depressive-like behaviour and levels of ACTH, corticosterone, and oxidative stress markers, with significant increase in antioxidant enzymes activities and total antioxidant status. In conclusion, Tualang honey mediated antidepressant-like effects in stressed rats, possibly acting via restoration of hypothalamic-pituitary-adrenal axis through its antioxidant properties.

Obesity is a risk factor for chronic diseases which can affect work productivity and physical function of employees
particularly among those in security sector. The study aimed to determine the association between obesity with total
days of sick leave and health related quality of life (HRQoL) among Malay male security officers. A cross-sectional
study was conducted among Malay male security officers working in a Malaysian higher learning institution. Subjects
were evaluated using anthropometric measurements, quality of life and number of sick leave taken within two months
prior to the study. A total of 194 subjects (mean age 40.12 ± 11.41 years) were recruited. A total of 30.4% were obese,
39.7% were pre-obese and only 29.9% had normal body weight or underweight. Central obesity was observed in 57.7%
of them and 87.1% shown excessive body fat percentage. Number of sick leave days was positively correlated with Body
Mass Index (BMI) (r = 0.162, p = 0.024) and waist circumference (r = 0.181, p = 0.012). Score of the general health
component was negatively correlated with BMI (r = -0.161, p = 0.025), waist circumference (r = -0.194, p = 0.007) and
body fat percentage (r = -0.191, p = 0.008). Physical functioning score was lowest in obese subjects than normal and
pre-obese subjects (p = 0.046). Score of the bodily pain component was positively correlated with waist circumference (r
= 0.156, p = 0.030). Obesity is associated with number of sick leave days and quality of life in the studied group. Hence,
body weight of the security staff should be monitored and appropriate intervention should be conducted to improve their
work attendance and quality of life.

Clinical versus ultrasound estimation of fetal weight

Raman S, Urquhart R, Yusof M

Aust N Z J Obstet Gynaecol, 1992 Aug;32(3):196-9.
PMID: 1445124

A prospective study was carried out on 50 patients who had their fetal weight estimated by 3 clinicians of different seniority and compared to the ultrasound estimated fetal weights using 3 different formulas. All the patients delivered within 24 hours of their clinical and ultrasound estimates. A wide range of birth-weights (1,800-4,500 g) was estimated among the 3 different races (Malay, Chinese and Indians). The results showed that there was no significant difference in birth-weight estimation amongst the 3 clinicians as well as between the 3 ultrasound formulas used. There was however significant difference between these 2 groups when compared with the actual birthweight with clinical estimation being superior to ultrasound estimation in our population. This level of significance did not extend beyond 4,000 g fetal weight (actual) thus making both clinical and ultrasound estimation of fetal weight equally accurate after 4,000 g. This has important implications for developing countries where there is a lack of technologically advanced ultrasound machines capable of doing sophisticated functions like fetal weight estimations but has experienced clinicians who could perform this function equally well if not better.

Fulltext Role of excitatory amino acid input in rostral ventrolateral medulla neurons in rats with obesity-induced hypertension

Suhaimi FW, Yusoff NH, Dewa A, Yusof AP

Acta Neurol Belg, 2010 Mar;110(1):57-64.
PMID: 20514927

Obesity is intimately associated with hypertension; increases in blood pressure are closely related to the magnitude of weight gain. The present study aims to determine whether the excitatory amino acid input to rostral ventrolateral medulla (RVLM) contributes to elevated blood pressure in rats with diet-induced obesity. Male Sprague-Dawley rats weighing 280 to 300 grams were fed with a low-fat diet (10% kcal from fat) or moderately high-fat diet (32% kcal from fat) for 16 weeks. At week 16, rats on the moderate high-fat diet were segregated into obesity-prone and obesity-resistant rats based on body weight distribution. Baseline mean arterial pressure (MAP) was significantly higher in obesity-prone rats as compared to obesity-resistant and rats on a low-fat diet. Bilateral injection of kynurenic acid (KYN) (40 nM) into the RVLM of the obesity-prone rats reduced MAP to levels significantly different from those observed in rats on a low-fat diet and obesity-resistant rats (no change in MAP). At a lower concentration (4 nM), KYN injection did not produce any change in MAP in any group. The results obtained suggest that excitatory amino acid input to the RVLM does contribute to the development of hypertension in rats with diet-induced obesity.

The effect of 10 days of intermittent fasting on Wingate anaerobic power and prolonged high-intensity time-to-exhaustion cycling performance

Naharudin MNB, Yusof A

Eur J Sport Sci, 2018 Jun;18(5):667-676.
PMID: 29485326 DOI: 10.1080/17461391.2018.1438520

Many physically active individuals have undertaken intermittent fasting to reduce their daily caloric intake. However, abstaining from meals for a specific length of time may lead to the acute disturbance of highly carbohydrate-dependent exercise performance. The purpose of this study was to observe the effect of 10 days of intermittent fasting on high-intensity type exercises, Wingate anaerobic (WT) and prolonged high-intensity time-to-exhaustion (HIT) cycling test. Twenty participants were randomised into an intermittent fasting (FAS) and a control group (CON). One day after baseline data collection on Day-0 where participants consumed their recommended daily caloric intake (FAS = 2500 ± 143 kcal day-1; CON = 2492 ± 20 kcal day-1) served over a course of five meals, the FAS group consumed only four meals where 40% was restricted by the omission of lunch (FAS = 1500 ± 55 kcal day-1). This diet was then continued for 10 days. Data on exercise performance and other dependent variables were collected on Day-2, -4, -6, -8 and -10. A reduction in WT power in the FAS group was observed on Day-2 (821.74 ± 66.07 W) compared to Day-0 (847.63 ± 95.94 W) with a moderate effect size (p weight and triglyceride were consistently reduced in the FAS group (p

Fulltext Protective effect of pulp oil extracted from Canarium odontophyllum Miq. Fruit on blood lipids, lipid peroxidation, and antioxidant status in healthy rabbits

Shakirin FH, Azlan A, Ismail A, Amom Z, Yuon LC

Oxid Med Cell Longev, 2012;2012:840973.
PMID: 22685623 DOI: 10.1155/2012/840973

The aim of this paper was to compare the effects of pulp and kernel oils of Canarium odontophyllum Miq. (CO) on lipid profile, lipid peroxidation, and oxidative stress of healthy rabbits. The oils are rich in SFAs and MUFAs (mainly palmitic and oleic acids). The pulp oil is rich in polyphenols. Male New Zealand white (NZW) rabbits were fed for 4 weeks on a normal diet containing pulp (NP) or kernel oil (NK) of CO while corn oil was used as control (NC). Total cholesterol (TC), HDL-C, LDL-c and triglycerides (TG) levels were measured in this paper. Antioxidant enzymes (superoxide dismutase and glutathione peroxidise), thiobarbiturate reactive substances (TBARSs), and plasma total antioxidant status (TAS) were also evaluated. Supplementation of CO pulp oil resulted in favorable changes in blood lipid and lipid peroxidation (increased HDL-C, reduced LDL-C, TG, TBARS levels) with enhancement of SOD, GPx, and plasma TAS levels. Meanwhile, supplementation of kernel oil caused lowering of plasma TC and LDL-C as well as enhancement of SOD and TAS levels. These changes showed that oils of CO could be beneficial in improving lipid profile and antioxidant status as when using part of normal diet. The oils can be used as alternative to present vegetable oil.

Poor appetite and inadequate food intake together with depression are associated with malnutrition, that will increase risk of morbidity and mortality among elderly people. Identifying factors associated with these conditions are essential for formulation of preventive strategies. Therefore, a study was conducted to identify factors associated with poor appetite and depression among institutionalised Chinese elderly people in Butterworth, Penang. A total of 100 Chinese elderly (49 men and 51 women) aged 60 years and above, (mean age ± SD of 74.7 ± 9.2 years), with no known terminal and mental illnesses from two nursing homes participated in this study. Subjects were interviewed to gather information on appetite using Council of Nutrition Appetite Questionnaire (CNAQ), depression using Geriatric Depression Scale (GDS) and also socio demographic and health status. Food intake was assessed using a combination of one-day food weighing and 24 hour diet recall. Body weight and height were measured. Results showed that the mean energy and nutrients intake did not achieve the Recommended Nutrient Intake of Malaysia (RNI), with the exception for vitamin C. Only 4% of the subjects were underweight and obese, 65% normal and 31% overweight. A total of 70% and 73% of subjects had poor appetite and depression, respectively. Subjects who had depression (adjusted OR = 2.78, 95% CI = 0.95-8.03), energy intake below RNI (adjusted OR = 2.34, 95% CI = 0.68-6.95) and difficulty to fall asleep at night (insomnia) (adjusted OR = 2.22, 95% CI = 0.72-6.82) were more likely to have poor appetite. Subjects who had poor appetite (adjusted OR = 3.36, 95% CI = 1.19-9.47) and insomnia (adjusted OR = 2.58, 95% CI = 0.83-7.98) were more likely to have depression. In conclusion, although the majority of subjects had normal body weight but the nutrient intake was inadequate. Poor appetite and depression were prevalent and interrelated and also strongly associated with insomnia.

Fulltext Use of SGLT-2 Inhibitors in Patients with Type 2 Diabetes Mellitus and Abdominal Obesity: An Asian Perspective and Expert Recommendations

Sheu WHH, Chan SP, Matawaran BJ, Deerochanawong C, Mithal A, Chan J, et al.

Diabetes Metab J, 2020 02;44(1):11-32.
PMID: 32097996 DOI: 10.4093/dmj.2019.0208

The prevalence of obesity in Asia is of epidemic proportions, with an estimated 1 billion overweight/obese individuals in the region. The majority of patients with type 2 diabetes mellitus (T2DM) are overweight/obese, which increases the risk of cardiorenal outcomes in these patients; hence, sustained reductions in body weight and visceral adiposity are important management goals. However, most of the glucose-lowering therapies such as insulin, sulfonylureas, glinides, and thiazolidinediones induce weight gain, which makes the management of overweight/obese T2DM patients challenging. Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are the only oral glucose-lowering agents that have been shown to reduce body weight and visceral adiposity. In addition, SGLT-2 inhibitors therapy reduces ectopic fat deposition and improves adipose tissue function and weight-related quality of life. In this article, we aim to consolidate the existing literature on the effects of SGLT-2 inhibitors in Asian patients with T2DM and to produce clinical recommendations on their use in overweight or obese patients with T2DM. Recommendations from international and regional guidelines, as well as published data from clinical trials in Asian populations and cardiovascular outcomes trials are reviewed. Based on the available data, SGLT-2 inhibitors represent an evidence-based therapeutic option for the management of overweight/obese patients with T2DM.

Evid Based Complement Alternat Med, 2021;2021:5525584.
PMID: 33976701 DOI: 10.1155/2021/5525584

Momordica charantia (MC) is popular for its medicinal uses especially for treating diabetic-related complications. However, the antiulcer activity of essential oil derived from the seeds has not been systematically studied. This study aims to evaluate the gastroprotective activities of essential oil derived from the seed of MC induced by hydrochloride acid/ethanol (HCl/EtOH) and indomethacin and pylorus-ligation model. Gastric ulceration was induced by oral administration of HCl/EtOH solution or indomethacin on day 7 after animals have been pretreated with testing compounds. The first group received just distilled water and the second group received ranitidine (100 mg/kg). Groups 3, 4, and 5 received 10, 50, and 100 mg/kg of essential oil based on their body weight (10 mL/kg), respectively. Macroscopically, pretreatment of essential oil extracted from MC significantly decreased ulceration induced by HCl/EtOH and indomethacin in vivo. Microscopically, essential oil also significantly suppressed the formation of edema, epithelial disruption, and mucosa erosions. Moreover, essential oil significantly elevated the pH without decreasing the total acidity of the gastric juice and was able to increase the amount of adherent mucus compared to control. Current results provide scientific basis to the ethno-pharmacological usage of the MC in preventing ulcer formation induced by HCl/EtOH and indomethacin.

Introduction: Literatures suggest that insufficient physical activity as one of the contributors to non-communicable chronic diseases; nevertheless, data on the physical activity level is sparsely reported among individuals practising a vegetarian diet in Malaysia. The current study aims to determine the prevalence of insufficient physical activity and its association with socio-demographic factors, lifestyle factors and body weight status among 273 individuals prac- tising a vegetarian diet in Klang Valley, Malaysia. Methods: A set of self-administered questionnaire was distributed to all vegetarians and their data on physical activity was determined using the Global Physical Activity Questionnaire (GPAQ). Results: The average years of practising vegetarianism was 14.2±9.6 years, and most of the vegetarians were practised ovo-vegetarian diet (44.0%). A majority of them were Chinese (54.9%) and female (64.8%), with an aver- age age of 47.5 ± 13.1 years. The prevalence of overweight and obesity were 27.5% and 8.1%, respectively. Accord- ing to GPAQ, about two in five vegetarians (46.2%) were having insufficient physical activity. Being females, older age, Chinese, married individuals, and those with high total household income level were found to be significantly associated with low physical activity level among Malaysian vegetarians (p

Increased peroxisome proliferator-activated receptor γ expression levels in visceral adipose tissue, and serum CCL2 and interleukin-6 levels during visceral adipose tissue accumulation

Yogarajah T, Bee YT, Noordin R, Yin KB

Mol Med Rep, 2015 Jan;11(1):515-20.
PMID: 25324014 DOI: 10.3892/mmr.2014.2686

This study was conducted to determine the mRNA and protein expression levels of peroxisome proliferator-activated receptors (PPARs) in visceral adipose tissue, as well as serum adipokine levels, in Sprague Dawley rats. The rats were fed either a normal (control rats) or excessive (experimental rats) intake of food for 8 or 16 weeks, then sacrificed, at which time visceral and subcutaneous adipose tissues, as well as blood samples, were collected. The mRNA and protein expression levels of PPARs in the visceral adipose tissues were determined using reverse transcription-polymerase chain reaction and Western blotting, respectively. In addition, the levels of adipokines in the serum samples were determined using commercial ELISA kits. The results revealed that at 8 weeks, the mass of subcutaneous adipose tissue was higher than that of the visceral adipose tissue in the experimental rats, but the reverse occurred at 16 weeks. Furthermore, at 16 weeks the experimental rats exhibited an upregulation of PPARγ mRNA and protein expression levels in the visceral adipose tissues, and significant increases in the serum levels of CCL2 and interleukin (IL)-6 were observed, compared with those measured at 8 weeks. In conclusion, this study demonstrated that the PPARγ expression level was likely correlated with serum levels of CCL2 and IL-6, molecules that may facilitate visceral adipose tissue accumulation. In addition, the levels of the two adipokines in the serum may be useful as surrogate biomarkers for the expression levels of PPARγ in accumulated visceral adipose tissues.

Fulltext Sonographic renal length and volume of normal Thai children versus their Chinese and Western counterparts

Rongviriyapanich C, Sakunchit T, Sudla C, Mungkung S, Pongnapang N, Yeong CH

Clin Exp Pediatr, 2020 Dec;63(12):491-498.
PMID: 32683809 DOI: 10.3345/cep.2019.01676

BACKGROUND: Renal size is an important indicator in the diagnosis of renal diseases and urinary tract infections in children.
PURPOSE: The purpose of this study is twofold. First, it aimed to measure the renal length and calculate the renal volume of normal Thai children using 2-dimensional ultrasonography (2D-US) and study their correlations with somatic parameters. Second, it aimed to compare the age-specific renal size of normal Thai children with the published data of their Western and Chinese counterparts.
METHODS: A total of 321 children (150 boys, 171 girls; age, 6-15 years) with a normal renal profile were prospectively recruited. All subjects underwent 2D-US by an experienced pediatric radiologist and the renal length, width, and depth were measured. Renal volume was calculated using the ellipsoid formula as recommended. The data were compared between the left and right kidneys, the sexes, and various somatic parameters. The age-specific renal lengths were compared using a nomogram derived from a Western cohort that is currently referred by many Thailand hospitals, while the renal volumes were compared with the published data of a Chinese cohort.
RESULTS: No statistically significant difference (P<0.05) was found between sexes or the right and left kidneys. The renal sizes had strong correlations with height, weight, body surface area, and age but not with body mass index. The renal length of the Thai children was moderately correlated (r=0.59) with that of the Western cohort, while the age-specific renal volume was significantly smaller (P<0.05) than that of the Chinese children.
CONCLUSION: Therefore, we concluded that the age-specific renal length and volume obtained by 2D-US would vary between children in different regions and may not be suitably used as an international standard for diagnosis, although further studies may be needed to confirm our findings.

Suriah AR, Chong TJ, Yeoh BY

Singapore Med J, 1998 Aug;39(8):348-52.
PMID: 9844494

AIM: To evaluate the anthropometric measurements and dietary intake of the free-living elderly in a Chinese community.
METHOD: A survey was carried out on 48 male and female subjects aged 60 to 96 years using anthropometric, dietary intake and questionnaire techniques.
RESULTS: The study indicated female subjects to have more health problems, like pain at the joints (33%), hypertension (17%) and diabetes (27%) as compared to the male subjects. Dietary intake analysis showed the Chinese male subjects to have a higher energy intake (1,623 kcal) compared to the females (1,197 kcal) even though they did not fulfill the recommended dietary intake. The intake for energy, fats and carbohydrates, was found to be significantly different (p < 0.05) between both sexes. Anthropometric measurements indicated male elderly subjects to be significantly heavier (p < 0.05, 55.4 kg) and taller (161.8 cm) than female elderly subjects (49.5 kg; 146.2 cm respectively). About half of the elderly were normal in their BMI (male 55.6%; female 50%) and only 6.6% of the female subjects were obese. More male subjects were found to be underweight (33%) compared to female subjects (17%). Waist hip ratio was 0.92 for male and 0.87 for female.
CONCLUSION: Our study showed that female elderly subjects had more health problems compared to male elderly subjects. On the whole, the elderly did not fulfill the recommended amount for energy intake while the percentage for carbohydrates, fats and protein from the total calorie intake were not in accordance with the healthy diet guidelines. Anthropometrically, male subjects were heavier and taller than female subjects. Looking at body mass index, most of the male elderly subjects were in the normal to underweight range. With these results, more research is warranted to give a clearer picture of the Chinese elderly in the country.

Validation of the Subjective Global Nutrition Assessment (SGNA) and Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP) to Identify Malnutrition in Hospitalized Malaysian Children

Ong SH, Chee WSS, Lapchmanan LM, Ong SN, Lua ZC, Yeo JX

J Trop Pediatr, 2019 02 01;65(1):39-45.
PMID: 29514329 DOI: 10.1093/tropej/fmy009

Background: Early detection of malnutrition in hospitalized children helps reduce length of hospital stay and morbidity. A validated nutrition tool is essential to correctly identify children at risk of malnutrition or who are already malnourished. This study compared the use of the Subjective Global Nutrition Assessment (SGNA, nutrition assessment tool) and Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP, nutrition screening tool) with objective nutritional parameters to identify malnutrition in hospitalized children.
Methods: A cross-sectional study was carried out in two general paediatric wards in a public hospital. SGNA and STAMP were performed on 82 children (52 boys and 30 girls) of age 1-7 years. The scores from both methods were compared against Academy of Nutrition and Dietetics/American Society of Parental and Enteral Nutrition Consensus Statement for identification of paediatric malnutrition. The objective measurements include anthropometry (weight, height and mid-arm circumference), dietary intake and biochemical markers (C-reactive protein, total lymphocytes and serum albumin). Kappa agreement between methods, sensitivity, specificity and cross-classification were computed.
Results: SGNA and STAMP identified 45% and 79% of the children to be at risk of malnutrition, respectively. Using a compendium of objective parameters, 46% of the children were confirmed to be malnourished. The agreement between SGNA and objective measurements (k = 0.337) was stronger than between STAMP and objective measurements (k = 0.052) in evaluating the nutritional status of hospitalized children. SGNA also has a 4-fold higher specificity (70.45%) than STAMP (18.18%) in detecting children who are malnourished.
Conclusion: SGNA is a valid nutrition assessment tool in diagnosing malnutrition status among hospitalized children in Malaysia. The discrepancy in specificity values between the two methods explains the distinguished roles between SGNA and STAMP. The use of STAMP will have to be followed up with a more valid tool such as SGNA to verify the actual nutrition status of the paediatric population.

Obesity is a multifactorial disease caused by the interaction of genetic, lifestyle and environmental factors. Common single nucleotide polymorphisms in the recently-described Fat Mass and Obesity-Associated (FTO) gene have been related to body weight and fat mass in humans and genome-wide association studies in several populations have indicated that the FTO rs9939609 variant is associated with obesity. Therefore, the objective of this study was to investigate the association of the FTO rs9939609 variant with obesity among 324 multi-ethnic Malaysians (98 Malays, 158 Chinese, 68 Indians) who attended the Kampar Health Clinic, Perak. With the overall minor A allele frequency (MAF) of 0.199, the distribution of genotypes and alleles was significantly different among ethnicities (MAF highest among Malays), but no association was found for obesity, related anthropometric measurements and gender. Subject with allele A had marginally but significantly higher waist circumference (p=0.015), thus the FTO rs9939609 allele was associated with central obesity [p=0.034 by Chi-square analysis; Odds Ratio (OR)=1.680 (CI=1.036, 2.724; p=0.035)]. However, this association was abolished when adjusted for age, gender and ethnicity (OR=1.455, CI=0.874, 2.42; p=0.149). In conclusion, the MAF of the FTO rs9939609 SNP was low as in other Asian populations and there was no evidence for an involvement of this SNP in obesity and obesity-related traits in this multi-ethnic Malaysian study group.

In order to assess the feasibility of various carbon sources and plant materials in increasing the growth rate and biomass productivity of Monoraphidium griffithii, ten carbon sources as well as six plant materials were tested in mixotrophic cultures with or without aeration. It was found that glucose, fructose, maltose, sodium acetate and mannitol were potential carbon sources for growth enhancement of M. griffithii. Supplementation of culture medium with these carbon sources resulted in approximately 1-4-fold increase in cell density compared to control in a small scale culture. In a larger scale mixotrophic culture with aeration, 0.05% mannitol and 0.1% fructose resulted in a decent 1-1.5-fold increase in final cell density, approximately 2-fold increase in growth rate and 0.5-1-fold increase in dry biomass weight. Findings from this study suggests that glucose, fructose, maltose and mannitol were potential organic carbon sources for mixotrophic culture of M. griffithii.
