Fulltext Effect of physical activity on fasting blood glucose and lipid profile among low income housewives in the MyBFF@home study

Omar A, Husain MN, Jamil AT, Nor NSM, Ambak R, Fazliana M, et al.

BMC Womens Health, 2018 07 19;18(Suppl 1):103.
PMID: 30066645 DOI: 10.1186/s12905-018-0598-9

BACKGROUND: Regular physical activity has always been strongly recommended for good cardiovascular health. This study aimed to determine the effect of physical activity on fasting blood glucose and lipid profile among low income housewives in Klang Valley.
METHODS: Data of 328 eligible housewives who participated in the MyBFF@Home study was used. Intervention group of 169 subjects were provided with an intervention package which includes physical activity (brisk walking, dumbbell exercise, physical activity diary, group exercise) and 159 subjects in control group received various health seminars. Physical activity level was assessed using short-International Physical Activity Questionnaire. The physical activity level was then re-categorized into 4 categories (active intervention, inactive intervention, active control and inactive control). Physical activity, blood glucose and lipid profile were measured at baseline, 3rd month and 6th month of the study. General Linear Model was used to determine the effect of physical activity on glucose and lipid profile.
RESULTS: At the 6th month, there were 99 subjects in the intervention and 79 control group who had complete data for physical activity. There was no difference on the effect of physical activity on the glucose level and lipid profile except for the Triglycerides level. Both intervention and control groups showed reduction of physical activity level over time.
CONCLUSION: The effect of physical activity on blood glucose and lipid profile could not be demonstrated possibly due to physical activity in both intervention and control groups showed decreasing trend over time.

PMID: 30682116 DOI: 10.1371/journal.pone.0211210

It remains widely perceived that early-onset Type 2 Diabetes (T2D) in children and adolescents is rare and clinically distinct from Type 1 Diabetes (T1D). We studied the challenges of classifying subtypes of early-onset diabetes using clinical features and biomarkers, and management of these patients. We reviewed retrospectively the record of patients < 25 years old who attended the diabetes clinic in Penang General Hospital, Malaysia between 1st December 2012 and 30th June 2015. We examined their clinical features, C-peptide and pancreatic autoantibodies. Comparisons were made between T1D and T2D for magnitude, demographics, metabolic status and complications. We studied 176 patients with a mean age of 20 ± 3.7 years, 43.2% had T1D, 13.6% had T2D, and 13.6% had mixed features of both. When tested, pancreatic autoantibodies were positive in 59.4% of the T1D. T2D presented two years later than T1D at 14.3 years, 20% were asymptomatic at presentation, and 50% required insulin supplementation despite fasting c-peptide of > 250 pmol/L. HbA1C of ≤ 8.0% (64 mmol/mol) was achieved in 30.3% of T1D, 58.3% of T2D on OAD and 16.7% of T2D on insulin. The T2D had greater cardiovascular risk with higher body mass index, more dyslipidaemia, higher blood pressure and earlier onset of nephropathy. The overlapping clinical features, variable autoimmunity, and beta-cell loss complicate classification of young diabetes. Pancreatic autoantibodies and C-peptide did not always predict diabetes subtypes nor respond to insulin. The poor metabolic control and high cardiovascular risk burden among the T2D highlight the need for population-based study and focused intervention.

Familial Paroxysmal Rhabdomyolysis, non-exertional type, in a Malay family - a case report

Hussain Imam Muhammad Ismail, Azizi Omar

Malaysian Journal of Child Health, 1993;5(1):57-61.
MyJurnal

Familial Paroxysmal Rhabdomyolysis of the non-exertional variety is a rare but treatable disorder previously not described in Malaysia. We report 3 Malay siblings of a consanguinous marriage who developed myoglobulinuria during a febrile illness. The first 2 died without being investigated, but the last had creatinine kinase levels of 24,800 UIL suggesting acute rhabdomyolysis. Fasting appears to be a major precipitating factor, and glucose infusions combined with alkaline diuresis may be life-saving.

PMID: 32987623 DOI: 10.3390/biom10101360

Catalpol was tested for various disorders including diabetes mellitus. Numerous molecular mechanisms have emerged supporting its biological effects but with little information towards its insulin sensitizing effect. In this study, we have investigated its effect on skeletal muscle mitochondrial respiration and insulin signaling pathway. Type-2 diabetes (T2DM) was induced in male C57BL/6 by a high fat diet (60% Kcal) and streptozotocin (50 mg/kg, i.p.). Diabetic mice were orally administered with catalpol (100 and 200 mg/kg), metformin (200 mg/kg), and saline for four weeks. Fasting blood glucose (FBG), HbA1c, plasma insulin, oral glucose tolerance test (OGTT), insulin tolerance test (ITT), oxygen consumption rate, gene (IRS-1, Akt, PI3k, AMPK, GLUT4, and PGC-1α) and protein (AMPK, GLUT4, and PPAR-γ) expression in muscle were measured. Catalpol (200 mg/kg) significantly (p < 0.05) reduced the FBG, HbA1C, HOMA_IR index, and AUC of OGTT whereas, improved the ITT slope. Gene (IRS-1, Akt, PI3k, GLUT4, AMPK, and PGC-1α) and protein (AMPK, p-AMPK, PPAR-γ and GLUT4) expressions, as well as augmented state-3 respiration, oxygen consumption rate, and citrate synthase activity in muscle was observed in catalpol treated mice. The antidiabetic activity of catalpol is credited with a marked improvement in insulin sensitivity and mitochondrial respiration through the insulin signaling pathway and AMPK/SIRT1/PGC-1α/PPAR-γ activation in the skeletal muscle of T2DM mice.

Effects of fasting in Ramadan on tropical Asiatic Moslems

Husain R, Duncan MT, Cheah SH, Ch'ng SL

Br J Nutr, 1987 Jul;58(1):41-8.
PMID: 3620437

1. Anthropometric variables, resting heart rate and respiratory gas exchange were measured in twelve male and nine female Asiatic adult Moslems during the month of Ramadan, the week before and the month after Ramadan. 2. Energy intakes were estimated from dietary recall during fasting and non-fasting conditions. 3. Both male and female subjects experienced a decrease in body mass with the reduction in energy intake during fasting. Males experienced a greater reduction than females in resting heart rate; females lost more body-weight and subcutaneous fat than males. 4. Urine output and fluid intake were measured in twelve male subjects for 1 d during each week of fasting and 1 d during the pre-fasting control period. Among the subjects examined, the Ramadan regimen did not result in changes in the pattern of fluid exchange.

Fulltext Ventilatory function in Malay Muslims during normal activity and the Ramadan fast

Duncan MT, Husain R, Raman A, Cheah SH, Ch'ng SL

Singapore Med J, 1990 Dec;31(6):543-7.
PMID: 2281349

Pulmonary function parameters were examined in a Malay Muslim population during normal activity and Ramadan fasting conditions. The validity of employing various lung function prediction formulae for the subjects was also assessed. Present findings indicate that the water deprivation regime and resultant dehydration during Ramadan did not cause significant changes in ventilatory functions. Although pulmonary prediction formulae based on Caucasian and African populations were inapplicable to the subjects examined, the equations derived from the neighbouring populations in Singapore could be employed.

Fulltext Intermittent Fasting and Obesity-Related Health Outcomes: An Umbrella Review of Meta-analyses of Randomized Clinical Trials

Patikorn C, Roubal K, Veettil SK, Chandran V, Pham T, Lee YY, et al.

JAMA Netw Open, 2021 12 01;4(12):e2139558.
PMID: 34919135 DOI: 10.1001/jamanetworkopen.2021.39558

Importance: Several meta-analyses of randomized clinical trials (RCTs) have demonstrated the many health benefits of intermittent fasting (IF). However, there has been little synthesis of the strength and quality of this evidence in aggregate to date.
Objective: To grade the evidence from published meta-analyses of RCTs that assessed the associations of IF (zero-calorie alternate-day fasting, modified alternate-day fasting, the 5:2 diet, and time-restricted eating) with obesity-related health outcomes.
Evidence Review: PubMed, Embase, and Cochrane database of systematic reviews were searched from database inception to January 12, 2021. Data analysis was conducted from April 2021 through July 2021. Meta-analyses of RCTs investigating effects of IF in adults were included. The effect sizes of IF were recalculated using a random-effects model. We assessed the quality of evidence per association by applying the GRADE criteria (Grading of Recommendations, Assessment, Development, and Evaluations) as high, moderate, low, and very low.
Findings: A total of 11 meta-analyses comprising 130 RCTs (median [IQR] sample size, 38 [24-69] participants; median [IQR] follow-up period, 3 [2-5] months) were included describing 104 unique associations of different types of IF with obesity-related health outcomes (median [IQR] studies per association, 4 [3-5]). There were 28 statistically significant associations (27%) that demonstrated the beneficial outcomes for body mass index, body weight, fat mass, low-density lipoprotein cholesterol, total cholesterol, triglycerides, fasting plasma glucose, fasting insulin, homeostatic model assessment of insulin resistance, and blood pressure. IF was found to be associated with reduced fat-free mass. One significant association (1%) supported by high-quality evidence was modified alternate-day fasting for 1 to 2 months, which was associated with moderate reduction in body mass index in healthy adults and adults with overweight, obesity, or nonalcoholic fatty liver disease compared with regular diet. Six associations (6%) were supported by moderate quality evidence. The remaining associations found to be significant were supported by very low (75 associations [72%]) to low (22 associations [21%]) quality evidence.
Conclusions and Relevance: In this umbrella review, we found beneficial associations of IF with anthropometric and cardiometabolic outcomes supported by moderate to high quality of evidence, which supports the role of IF, especially modified alternate-day fasting, as a weight loss approach for adults with overweight or obesity. More clinical trials with long-term follow-up are needed to investigate the effects of IF on clinical outcomes such as cardiovascular events and mortality.

Introduction: Diabetes is associated with a high risk of cardiovascular disease. The management of blood glucose, dyslipidaemia and other modifiable risk factor, is a key element in the multifactorial approach to prevent complications of type 2 diabetes. Materials and Methods: A cross sectional study was conducted to determine the level of glycaemic control, lipid profile, blood pressure and body weight status among type 2 diabetics in rural Malaysia. A total of 237 diabetic subjects participated in this study. Physical examination was carried out, including measurements of height, weight, waist and hip circumferences, and systolic and diastolic blood pressure. Fasting venous blood samples were collected to determine the glucose level and lipid profile. Results: About 70% of the subjects had a high body mass index (BMI), equal to or above 25 kg/m2. More than 60% of the subjects had systolic blood pressure >= 140 mmHg and/or diastolic >=90 mmHg. Mean fasting blood glucose was 9.84±4.54 mmol/L. Mean total cholesterol was 5.18±1.35 mmol/L. High density lipoprotein cholesterol (HDLC) and triglyceride (TG) and glucose levels were higher in male than in female, but not statistically significant (p>0.05). However, low density lipoprotein cholesterol (LDLC) was higher in females than males (p

Introduction: Hypercholesterolemia has been proven as a main pathogenic trigger for pathogenesis of atherosclerosis. Atherosclerosis characterised by chronic inflammatory process and increased expression of inflammatory markers. In this study; Trihoney (a combination of three types of natural honey namely: Trigona, mellifera, and Dorsata)
was investigated for its anti-inflammatory effect in hypercholesterolemic atherosclerotic rabbits. Methods: Thirty
male New Zealand white rabbits (NZW) were grouped into: normal diet (C), normal diet with 0.6g/kg/day of Trihoney (C+H), 1% cholesterol diet (HCD), 1% cholesterol diet with 0.6g/kg/day of Trihoney (HCD+H), and 1%
cholesterol diet with 2mg/kg/day of atorvastatin (HCD+At.). After 12 weeks of starting the experiment, animals were
sacrificed and serum analysed for homocysteine and pro-atherogenic inflammatory markers such as: interleukin-1β
(IL-1β), interleukin-6 (IL-6), and tumour necrosis factor-α (TNF-α). Fasting serum glucose was analysed to assess glycaemic status. Results: Trihoney treated group showed significantly lower (p

Prevalence of diabetes is escalating both globally as well as in Malaysia. With the epidemic of diabetes and its related morbidities and mortalities, health care professionals are facing an unprecedented challenges in controlling the disease. Objective: To determine the metabolic control and the cardiovascular risk factors among type 2 diabetic patients in a primary care setting. Method: This was a cross sectional study conducted in a primary care clinic in Selangor, Malaysia. Inclusion criteria were all type 2 diabetic patients aged 18 and above and were being followed-up for more than six months prior to the recruiting period in May 2009. The demographic data were obtained through face- to-face interview. Height, weight and blood pressure of the patients were taken during the day of data collection. The co-morbidities and laboratory results were obtained from the medical records. Results: Two-hundred patients were recruited. The mean age was 58.6 (SD=10.5) with 79.0% of the patients aged more than 50 years old. The majority of the patients were female (62.5%). One-tenth (11.5%) were smokers. More than half of the patients (64.0%) had co-morbid of hypertension and half of them (50.5%) had dyslipidaemia. A total of 72.5% of the patients had 3 or more cardiovascular risk factors. Less than one fifth of the patients had achieved the target of control for glycaemia, blood pressure, LDL and BMI. Those age 60 and above had significantly higher proportion of patients achieving fasting blood glucose control (p=0.033). Conclusion: The majority of type 2 diabetic patients had multiple cardiovascular risk factors (3 or more risk factors) and had not achieved the recommended goals in
metabolic control.

Asian-Australas J Anim Sci, 2013 May;26(5):700-4.
PMID: 25049841 DOI: 10.5713/ajas.2012.12561

A study was conducted to investigate the effects of feeding medium chain triacylglycerol (MCT) on growth performance, plasma fatty acids, villus height and crypt depth in preweaning piglets. A total of 150 new born piglets were randomly assigned into one of three treatments: i) Control (no MCT); ii) MCT with milk (MCT+milk); iii) MCT without milk (MCT+fasting). Body weight, plasma fatty acid profiles, villus height and crypt depth were measured. Final BW for the Control and MCT+fasting was lower (p<0.05) than MCT+milk. The piglets fed with MCT regardless of milk provision or fasting had greater medium chain fatty acids (MCFA) than the Control. In contrast, the Control had greater long chain fatty acid (LCFA) and unsaturated fatty acid (USFA) than the MCT piglets. The piglets fed with MCT regardless of milk provision or fasting had higher villus height for the duodenum and jejunum after 6 h of feeding. Similar observations were found in piglets fed with MCT after 6 and 8 days of treatment. This study showed that feeding MCT to the piglets before weaning improved growth performance, with a greater concentration of MCT in blood plasma as energy source and a greater height of villus in duodenum, jejunum and ileum.

Strategising, which is an effective workplace intervention to curb cardiovascular disease (CVD), requires understanding of the CVD risk related to a specific working population. The Framingham Risk Score (FRS) is widely used in predicting the ten-year CVD risk of various working populations. This study aimed to use FRS to determine the ten-year CVD risk amongst workers in a tertiary healthcare setting and its associated factors. A cross-sectional study was conducted on workers who participated in the special health check programme at the staff clinic of a tertiary healthcare institution in Kuala Lumpur, Malaysia. A set of data sheets was used to retrieve the workers’ sociodemographic and CVD risk information. The prevalence of high, moderate and low ten-year CVD risk was 12.8%, 20.0% and 67.2%, respectively. Workers in the high-risk group were older [mean age: 54.81 (standard deviation, 5.72) years], male (44%), smokers (72.7%) and having hyperglycaemia (46.7%) and hypertriglyceridemia [median triglycerides: 1.75 (interquartile range, 1.45) mmol/L]. Diastolic blood pressure (aOR 1.07, 95% CI: 1.01,1.14), hyperglycaemia (aOR 8.80, 95% CI: 1.92,40.36) and hypertriglyceridemia (aOR 4.45, 95% CI: 1.78,11.09) were significantly associated with high ten-year CVD risk. Diastolic blood pressure (aOR 1.08, 95% CI: 1.03,1.13) and hypertriglyceridemia (aOR 2.51, 95% CI: 1.12-5.61) were significantly associated with moderate ten-year CVD risk. The prevalence of high and moderate ten-year CVD risk was relatively high. Amongst the workers in the high-risk group, they were older, male, smokers and with high fasting blood sugar and triglyceride. Understanding the ten-year CVD risk and its associated factors could be used to plan periodic workplace health assessment and monitor to prevent CVD

Diabetes emergencies around Ramadan study (DEARS) - A multi-center study of diabetes emergencies admitted before, during and after Ramadan in Malaysia

Tong CV, Yow HY, Mohd Noor N, Hussein Z, DEARS (Diabetes Emergencies Around Ramadan Study) study group

Diabetes Res Clin Pract, 2021 May;175:108854.
PMID: 33961901 DOI: 10.1016/j.diabres.2021.108854

OBJECTIVE: The objective of this study was to determine admissions for diabetes emergencies among patients who fasted or planned to fast one month before, during and one month after Ramadan 2019 in public hospitals in Malaysia.
MATERIALS AND METHODS: This was a cross sectional prospective study done in 18 public hospitals in Malaysia from 7/4/2019 to 2/7/2019. Data was collected prospectively with universal sampling. All adult Muslim patients with previous diagnosis of diabetes, who were admitted for hypoglycemia, DKA or HHS were included if they had fasted and had intentions to fast.
RESULTS: 295 admissions for diabetes emergencies were analyzed. The pre-Ramadan period recorded the highest number of admissions (119) followed by during (106) and post-Ramadan (70). Admissions for hyperglycemic emergencies accounted for 2/3 of total admissions. 37% of admissions for hypoglycemia occurred during pre-Ramadan period compared to 32.1% during Ramadan. Contributing factors included use of sulphonylurea (59.6%), presence of nephropathy (54.5%) and past history of hypoglycemia (45.5%). Admissions for DKA were more common than HHS (119 versus 77) and highest during Ramadan period (36.1%). Most of the admissions for hyperglycemic emergencies were among those with Type 2 diabetes (75.9% for DKA and 97.4% for HHS). Only 31.5% of patients admitted for diabetes emergencies recalled having received Ramadan advice in the past.
DISCUSSION: Admissions for diabetes emergencies were highest during pre-Ramadan period followed by Ramadan and post-Ramadan period. This suggests that fasting during Ramadan does not increase admissions for diabetes emergencies.

PMID: 32330510 DOI: 10.1016/j.diabres.2020.108154

AIMS: To explore the real-world safety and effectiveness of gliclazide modified release (MR) in patients with type 2 diabetes mellitus (T2DM) fasting during Ramadan.
METHODS: DIA-RAMADAN (NCT04132934) was a prospective, international, observational study conducted in nine countries. Patients >18 years of age with T2DM (N = 1244) were examined at an inclusion visit (V0) occurring 6-8 weeks before the start of Ramadan. Patients received a diary to report treatment changes, hypoglycaemic events (HEs), and other adverse events. Gliclazide MR was taken once daily for 14-18 weeks. A second visit (V1) was conducted 4-6 weeks after the end of Ramadan. The primary endpoint was the proportion of patients reporting ≥1 symptomatic HE. Changes in HbA1c, fasting plasma glucose (FPG), and body weight were secondary endpoints.
RESULTS: The proportion of patients reporting ≥1 symptomatic HE during Ramadan was low (2.2%) with no reported severe HEs. There was a significant reduction in HbA1c (-0.3%), FPG (-9.7 mg/dL), body weight (-0.5 kg) and body mass index (-0.2 kg/m2) between V0 and V1 (p

ScientificWorldJournal, 2013;2013:308041.
PMID: 24311975 DOI: 10.1155/2013/308041

This study was done to observe the anthropometry and body composition changes before, during, and after the holy month of Ramadan. This study was carried out on 46 staff from one of the local universities, which comprised of 14 males and 32 females ranging in age from 25 to 40 years old. There were four sessions done to complete this study, namely, a week before Ramadan (T1), 1st week of Ramadan (T2), 3rd week of Ramadan (T3), and a month after Ramadan (T4). All subjects were assessed according to weight, body circumference, and body composition status. It was found that subjects with different weight status showed a significant reduction in weight (P < 0.01) but no significant reduction in body fat percentage (P < 0.05). The findings suggest that weight reduction does not promise a reduction in body fat. Changes in neck circumference were only found in normal subjects. Hence, it can be said that overweight and obese subjects showed no changes in anthropometry status during Ramadan. No changes in body composition were reported in all three weight groups except for trunk body fat. In conclusion, normal subjects showed significant changes in various anthropometry parameters, but overweight and obese subjects showed no obvious difference.

Hussin NM, Shahar S, Teng NI, Ngah WZ, Das SK

J Nutr Health Aging, 2013;17(8):674-80.
PMID: 24097021 DOI: 10.1007/s12603-013-0344-9

OBJECTIVE: An intervention study on the FCR (Fasting and Calorie Restriction) dietary regime was carried out to determine its efficacy in improving mood states and depression status among ageing men.
SUBJECTS: A total of 32 healthy males (Mean±SD), aged 59.7±6.3 years, with a BMI of 26.7±2.2 kg/m2 were recruited to the study.
METHOD: Participants were randomized to either the FCR group (and were instructed to follow a calorie restricted dietary regime with intermittent fasting) or to the control group (in which individuals were asked to maintain their current lifestyle), for a 3 month period. Mood was assessed using the Profile of Mood States and depression was assessed using Beck Depression Inventory-II and Geriatric Depression Scale-15 at baseline, week 6 and week 12 of the intervention.
RESULTS: A total of 31 subjects completed the study (n=16, FCR and n=15, control). Significant decreases in tension, anger, confusion and total mood disturbance and improvements in vigor were observed in participants in the FCR group compared to the control group (p<0.05). No significant changes in mean depression scores were observed. Weight, BMI and percent body fat were reduced by 3.8%, 3.7% and 5.7% respectively in the FCR group.
CONCLUSIONS: Our findings show that a FCR dietary regime is effective in improving mood states and nutritional status among ageing men.

Fulltext Exploring the experiences and perceptions of haemodialysis patients observing Ramadan fasting: a qualitative study

Adanan NIH, Adnan WAHWM, Khosla P, Karupaiah T, Daud ZAM

BMC Nephrol, 2021 02 02;22(1):48.
PMID: 33530941 DOI: 10.1186/s12882-021-02255-8

BACKGROUND: The festival of Ramadan is a month of spiritual reflection for Muslims worldwide. During Ramadan, Muslims are required to refrain from eating and drinking during daylight hours. Although exempted from fasting, many patients undergoing maintenance haemodialysis (HD) opt to participate in this religious practice. Many studies have explored the effects of Ramadan on health outcomes, however, the exploration from patients' own point of view pertaining to this religious practice is lacking. Thus, we aimed to explore the experiences and perceptions of Muslim HD patients observing Ramadan fasting from three HD centres in Klang Valley, Malaysia.
METHOD: An exploratory phenomenology qualitative study was conducted whereby subjects were purposively selected based on previous experience in observing Ramadan fasting. Face-to-face in-depth interviews were conducted, and study data were analyzed thematically and iteratively coded using a constant comparison method.
RESULTS: Four major themes emerged from the data, namely: (i) "fasting experiences", (ii) "perceived side effects of fasting", (iii) "health-seeking behavior" and, (iv) "education and awareness needs". Patients expressed the significance of Ramadan fasting as well as the perceived impact of fasting on their health. Additionally, there is lack of health-seeking behaviour observed among patients thus, raising needs for awareness and education related to Ramadan fasting.
CONCLUSIONS: Findings of this study shed light on patients' experiences and perceptions regarding Ramadan fasting which warrants the needs for an effective communication between patients and health care practitioners through a structured-Ramadan specific education program.

Cardiovascular risk factors in pre-pubertal Malays: effects of diabetic parentage

Choo KE, Lau KB, Davis WA, Chew PH, Jenkins AJ, Davis TM

Diabetes Res Clin Pract, 2007 Apr;76(1):119-25.
PMID: 16979774 DOI: 10.1016/j.diabres.2006.08.006

Diabetes prevalence is increasing rapidly in Asian populations but the influence of a family history of diabetes on cardiovascular risk is unknown. To assess this relationship, 120 urban-dwelling Malays were recruited to a cross-sectional case-control study. Sixty were pre-pubertal children, 30 of diabetic parentage (Group 1) and 30 with no diabetes family history (Group 2). Group 1 and 2 subjects were the offspring of adults with (Group 3) or without (Group 4) type 2 diabetes. Subjects were assessed for clinical and biochemical variables defining cardiovascular risk. Principal component analysis assessed clustering of variables in the children. Group 1 subjects had a higher mean waist:hip ratio, diastolic blood pressure and HbA(1c) than those in Group 2, and a lower HDL:total cholesterol ratio (P<0.03). Although there were no correlations between Group 1 and 3 subjects for cardiovascular risk variables, significant associations were found in Groups 2 and 4, especially HbA(1c) and insulin sensitivity (P< or =0.004). Of five separate clusters of variables (factors) identified amongst the children, the strongest comprised diabetic parentage, HbA(1c), insulin sensitivity and blood pressure. Features of the metabolic syndrome are becoming evident in the young non-obese children of diabetic Malays, suggesting that lifestyle factors merit particular attention in this group.

In the present study, the combined effects of hypoxia and nutritional status were examined in common carp (Cyprinus carpio), a relatively hypoxia tolerant cyprinid. Fish were either fed or fasted and were exposed to hypoxia (1.5-1.8mg O2L(-1)) at or slightly above their critical oxygen concentration during 1, 3 or 7days followed by a 7day recovery period. Ventilation initially increased during hypoxia, but fasted fish had lower ventilation frequencies than fed fish. In fed fish, ventilation returned to control levels during hypoxia, while in fasted fish recovery only occurred after reoxygenation. Due to this, C. carpio managed, at least in part, to maintain aerobic metabolism during hypoxia: muscle and plasma lactate levels remained relatively stable although they tended to be higher in fed fish (despite higher ventilation rates). However, during recovery, compensatory responses differed greatly between both feeding regimes: plasma lactate in fed fish increased with a simultaneous breakdown of liver glycogen indicating increased energy use, while fasted fish seemed to economize energy and recycle decreasing plasma lactate levels into increasing liver glycogen levels. Protein was used under both feeding regimes during hypoxia and subsequent recovery: protein levels reduced mainly in liver for fed fish and in muscle for fasted fish. Overall, nutritional status had a greater impact on energy reserves than the lack of oxygen with a lower hepatosomatic index and lower glycogen stores in fasted fish. Fasted fish transiently increased Na(+)/K(+)-ATPase activity under hypoxia, but in general ionoregulatory balance proved to be only slightly disturbed, showing that sufficient energy was left for ion regulation.
