BACKGROUND: Vitamin D deficiency (VDD) has been related to vitamin D binding protein (GC) gene polymorphism, demographics and lifestyle factors in different populations. However, previous studies only focused on demographic and lifestyle factors or genetic factors alone. Therefore, this cross-sectional study aimed to assess the association between GC gene polymorphism, demographics and lifestyle factors with VDD among Malaysian pregnant women.
METHOD: Information on demographic characteristics, dietary vitamin D intake from supplement and food, time spent outdoors, skin type and clothing were collected using a questionnaire. Plasma total 25-hydroxyvitamin D (25OHD) levels were measured using an Ultra-High-Performance Liquid Chromatography (UHPLC). Maternal GC single nucleotide polymorphisms (SNPs) (rs4588 and rs7041) were determined using restriction fragment length polymorphism (RFLP) technique.
RESULTS: Results showed that 50.2% of pregnant women were vitamin D deficient (25OHD

Fulltext Vitamin B12 deficiency presenting as pancytopenia in pregnancy: a case report

Idris N, Arsyad A

Malays Fam Physician, 2012;7(2-3):46-50.
PMID: 25606257 MyJurnal

Vitamin B12 deficiency is a well-known cause of megaloblastic anaemia and pancytopenia. However, the incidence in pregnancy is rarely reported. We present a case of a 32-year old multigravid woman who was diagnosed with megaloblastic anaemia since 22 weeks gestation and progressed to develop severe pancytopenia at 30 weeks gestation. She was also diagnosed with vitamin B12 deficiency related to dietary and sociocultural habits. Folate and iron levels were normal throughout pregnancy. Treatment with parenteral cyano-cobalamin resulted in sustained improvement of haematological parameters. The pregnancy was carried to term and the baby was born weighing 2,050gm but otherwise well at birth and had normal developmental milestones thereafter. This case illustrates the clinical presentation of maternal vitamin B12 deficiency and demonstrates the importance of detecting and treating maternal vitamin B12 deficiency during pregnancy in at-risk patients. Failure to diagnose and institute treatment carries significant risks to both mother and child. Oral vitamin B12 supplementation should be considered for patients who are strict vegetarians or consume very little animal products.

Severe jaundice (serum bilirubin level > 340 gmol/L) occurred in 81 infants admitted to the Neonatal Intensive Care Unit (NICU) of the Maternity Hospital Kuala Lumpur (MHKL) in 1993. Of these 46 (56.8%) underwent 53 exchange transfusions. In-patient case notes were available for study on 41 of them. Two infants had no cause identified while 12 were associated with prematurity, 13 ABO incompatibility, 8 G6PD deficiency, 6 sepsis 2 Rh isoimmunisation and 6 miscellaneous causes. In 14 infants it was felt that exchange transfusions might have been avoided if they were detected earlier and phototherapy instituted promptly. Twenty six (26) infants were deemed to have been given phototherapy at the appropriate time but jaundice increased to exchange transfusion levels, threshold values depending on the unit in charge. Use of higher intensity phototherapy might have been more effective in some of the cases. Available data showed similar outcomes in both groups.

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

A cross-sectional study was undertaken to evaluate if outpatient administration of in-travenous iron sucrose complex (Venofer) was a sensible option in treating iron defi-ciency anaemia during pregnancy and puerperium. A total of 120 patients with iron deficiency anaemia were recruited from the Obstetric Day Care Clinic at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) over 18 months from March 2003 to August 2004. The main outcome measures were haemoglobin increment, patients’ compliance, adverse effects and saving from hospitalization fees. The pre-treatment haemoglobin (Hb) level was 8.5+0.85g/dl for the antenatal patient and 7.6+0.80 g/dl in the post-partum group. The mean post-treatment haemoglobin increment at day four-teenth was 3.52+0.75g/dl. One patient developed skin rash while another had low-grade pyrexia. Seven patients experienced mild metallic taste. There were no serious side effects or anaphylactic reactions. Ten patients (8.3%) did not complete their ther-apy - eight delivered before completion of treatment; another two defaulted following delivery. The average number of Venofer used was seven ampoules i.e. 700mg per person, most of them required three sessions to complete the course. Outpatient treatment allows each patient to save hospitalization fees of RM45 per day, which to-talled up to RM135 for a 3-days ward stay. An estimation of RM16,200 hospitalization fees for the 120 patients was avoided during the study period. In conclusion, outpatient treatment of anaemia in pregnancy and post-partum period using Venofer was safe and feasible, with high patient compliant and cost-savings from hospitalization fees.

MyJurnal

The Orang Asli of Malaysia continue to experience poor health. There appears to be stagnation of certain aspect of their health status. Underweight (low weight-for-age) and stunting (low height-for-age) are significant amongst Orang Asli children. Worm infestation such as Ascaris, Trichuris and hookworm continue to afflict Orang Asli communities in Malaysia. Orang Asli communities can also be afflicted by other kinds of parasites, e.g. malaria parasites, microsporida parasites and Cryptosporidium parasites. Thus, primary care doctors who treat Orang Asli patients should be on the lookout for malnutrition and its effects (including anaemia, iodine deficiency, Vitamin A deficiency) as well as worm and parasite infestations. Such patients may need to undergo de-worming at regular intervals because of the tendency to get re-infected. Primary care doctors also need to be aware of possible interactions between infestations and nutritional deficiencies.

PMID: 27781105

An analysis of the impact of orphanhood at antiretroviral therapy (ART) initiation on HIV outcomes in Asia included 4300 children; 51% were male. At ART initiation, 1805 (42%) were non-orphans (median age: 3 years), 1437 (33%) were single orphans (6 years) and 1058 (25%) were double orphans (7 years). Ten-year post-ART survival was 93.4-95.2% across orphan categories. Clinic transfers were higher among single and double orphans than non-orphans (41% vs 11%, P<0.001). On multivariate analysis, children ≥3 years at ART initiation (hazard ratio 1.58 vs <3 years, 95% confidence interval: 1.11-2.24) were more likely to be lost to follow-up. Although post-ART mortality and retention did not differ by orphan status, orphans were at greater risk of starting ART at older ages, and with more severe immunosuppression and poorer growth.

Fulltext Assessment of Toxicity and Beneficiary Effects of Garcinia pedunculata on the Hematological, Biochemical, and Histological Homeostasis in Rats

Paul S, Ali MY, Rumpa NE, Tanvir EM, Hossen MS, Saha M, et al.

Evid Based Complement Alternat Med, 2017;2017:4686104.
PMID: 28243309 DOI: 10.1155/2017/4686104

This study was undertaken to investigate the toxicological profile of a methanolic extract of Garcinia pedunculata fruit in rats by conducting hematological, biochemical, and histopathological examinations. Long Evans rats were divided into four groups, each with 6 animals, and were treated with three oral doses (250, 500, and 1000 mg/kg) once daily for 21 days. The extract did not cause significant changes in body and relative organ weight, percent water content, or hematological parameters at any administered doses. However, a significant dose-dependent positive effect in serum lipid profile and all atherogenic indices including the cardiac risk ratio, Castelli's risk index-2, and the atherogenic coefficient were observed. Significant increases in the levels of iron and decreases in serum alkaline phosphatase, alanine transaminase, and lactate dehydrogenase activities and the levels of serum glucose were noted when the extract was administered at the highest dose (1000 mg/kg). Histopathological examination of the target tissues further confirmed that the extract was safe and had no observed toxicological features. Our study indicates that G. pedunculata fruit is nontoxic, has the potential to be effective against atherosclerosis, and may be used as a hepatoprotectant. The fruit extract is also beneficial to those with iron deficiency and hyperglycemia.

Introduction: Scarcity of data found in regard to association of vitamin D level with bone mineral density (BMD). Our study aimed to determine the correlation of vitamin D with BMD and intact parathyroid hormone (iPTH) among healthy Malay adult. Methods: This cross-sectional study recruited 126 healthy Malay volunteers (aged 21–45 years old) from Kota Bharu, Malaysia. Serum total calcium, albumin, phosphorus, 25-hydroxyvitamin D (25(OH)D), and iPTH were measured. BMD was assessed with dual energy X-ray absorptiometry (DXA) scan over left hip (right hip in case of problem with left hip) and lumbar spine (L1 – L4 vertebrae). Results: The mean serum 25(OH)D was 38.91
± 14.07 nmol/L. Out of 126 study subjects, 104 subjects (82.5%) had insufficient level of vitamin D (< 50 nmol/L). Mean hip and lumbar BMD were 0.952 ± 0.145 g/cm2 and 1.006 ± 0.133 g/cm2 respectively. According to T-score, 93 subjects (73.8%) had normal T-score of  -1, 33 subjects (26.2%) had osteopenia (T-score -2.5 to -1) and none had osteoporosis (T-score  -2.5). Significant positive correlation between serum 25(OH)D and hip BMD (r = 0.234, p = 0.009) was observed, but no correlation was found between serum 25(OH)D and lumbar BMD. Meanwhile, significant inverse correlation between serum 25(OH)D and iPTH was observed (r = -0.324, p < 0.001). Conclusion: High prevalence of vitamin D insufficiency was observed among healthy Malay population, but majority had normal bone density. Nonetheless, serum 25(OH)D was positively correlated with BMD and inversely correlated with iPTH. Our findings support the role of vitamin D for maintaining bone health.

Introduction: Glucose-6-phosphate dehydrogenase (G6PD) deficiency causes red blood cell destruction due to oxi- dative stress. G6PD is essential for NADPH conversion; which is critical for glutathione reductase to prevent damage to cellular structures. In Malaysia, blood donors are not routinely screened for G6PD deficiency. We hypothesise that G6PD-deficient red blood cells are more likely to haemolyse during storage due to increased oxidative molecules. The objectives of this study were to determine the prevalence of G6PD deficiency among blood donors, describe their characteristics and to evaluate the effects of storage on G6PD-deficient donated blood. Methods: This study was conducted at selected mobile donation centres in Terengganu. Consented blood donors were screened for G6PD sta- tus using fluorescent spot tests (FST). G6PD enzyme activities were measured for donors who were G6PD deficient. Effects of storage on haemolysis from G6PD-deficient donors were compared with non G6PD-deficient group. Sixty ml of blood was collected from blood unit to transfer pouch for estimation of haemoglobin (Hb), plasma Hb, per- centage of haemolysis and plasma potassium. Serial sampling with a 7-day interval was done from Day 1 to Day 35. Statistical analysis was considered significant if p 0.05. Results: A total of 440 blood donors were screened and 12 male donors were found to be G6PD deficient by FST. Enzymatic activities were measured in 11 donors as one donor sample failed to be sent to the centre due to logistic problem. Their enzymatic activities ranged from 1.66-2.93 U/g Hb whereby 6 have severe deficiency and the other 5 were categorised as partial deficiency. Donors were asymp- tomatic for haemolytic episode. Serial sampling showed there was no significant difference of haemolytic parameters in blood units of G6PD-deficient donors as compared to control (p>0.05). Conclusion: Prevalence of G6PD blood donors in Terengganu mobile centres was 2.7%. G6PD enzyme activities did not correlate with clinical symptoms. Haemolytic parameters were not affected in blood units which were G6PD-deficient.

Introduction: Atopic dermatitis (AD) and its severity has been inconsistently associated with lower vitamin D levels as multiple other factors that influence vitamin D status were not always assessed. Methods: A case control study involving AD patients and controls 18 years old was performed. Exclusion criteria were systemic immunosuppres- sion  4 weeks prior to recruitment, renal or hepatic impairment, parathyroid diseases and vitamin D or calcium supplementation. Healthy controls were matched for age, gender, ethnicity, Fitzpatrick skin type and body mass index (BMI). Sun exposure, a 3-day, 24-hour dietary recall and serum 25-hydroxyvitamin D were measured. Re- sults: 38 AD patients and 38 controls participated. Majority had Fitzpatrick skin type IV. Vitamin D was lower in AD [15.9(9.9-24.0)ng/ml] than controls [17.3(14.4-27.2)ng/ml], p= 0.028. It was sufficient in 16(42.1%) AD and 15(39.5%) controls, insufficient in 7(18.4%) AD and 22(57.9%) controls and deficient in 15(39.5%) AD compared to 1(2.6%) control. Sun exposure was similar in both groups. AD had significantly higher dietary vitamin D intake [1.5(0.6-3.1) vs 0.6 (0.3-1.0)µg]. AD was an independant risk for vitamin D deficiency with OR 17.52; 95%CI:1.4-
212.7 and vitamin D insufficiency OR 0.26;95%CI:0.07-0.95. Vitamin D levels did not correlate with AD severity. Conclusion: AD is a risk for vitamin D deficiency despite higher dietary intake and similar skin type, BMI and sun exposure as controls.

Introduction: Iron deficiency anaemia (IDA) is endemic especially in the under-developed and developing countries and is a major public health concern. Improving nutrition is one of the ways to alleviate this condition. Consumption of locally available and affordable food such as date palm and goat milk which are rich in iron is one of the ways to overcome IDA. This study is aimed at evaluating the effect of date palm and goat milk supplementation on hae- matological parameters and iron bioavailability in IDA rats. Methods: 24 male Wistar rats were randomly divided into normal control and IDA group. The normal control was fed with normal diet and water ad libitum while the IDA group were fed on iron-deficient diet for two weeks to induce iron deficiency. The IDA rats were further divided into subgroups; each being supplemented with date palm, goat milk, a combination of date palm and goat milk, and ferrous fumarate as positive control. Blood were collected after 28 days for haematological parameters and iron profile determination. Iron bioavailability was assessed using the haemoglobin regeneration efficiency (HRE) index. Data was analysed by Student T Test and ANOVA using SPSS 23.0 software with p value < 0.05 considered as sta- tistically significant. Results: Supplementation of date palm and goat milk for 28 days significantly improved Hb, RBC, PCV, MCV, MCH, serum iron and transferrin saturation (p

We report a 33-year-old Malay woman presented with acute left dense hemiparesis and an NIHSS score of 11/15. Computed tomography (CT) scan brain showed a massive right middle cerebral artery (MCA) territory infarct. The right internal carotid artery (ICA) and right proximal MCA were shown occluded from digital substraction angiography (DSA). Carotid dissection, carotid canal anomaly, and intercavernous communication were systematically ruled out. She had no risk factors for atherosclerosis. The connective tissue screening and thrombophilic markers were negative. However, she was anaemic on admission and subsequent investigations revealed that she had alpha-thalassemia and iron deficiency anaemia. The right ICA remained occluded from a repeat CT cerebral angiogram after one year, but otherwise she was neurologically stable. This case illustrates an unusual association between intracranial vessel occlusion with iron deficiency anaemia and alpha-thalassemia trait.

Folate and methionine are critical for one-carbon metabolism impacting DNA synthesis, repair, and methylation processes, as well as polyamine synthesis. These micronutrients have been implicated in colorectal cancer risk. There are, however, inconsistencies within the literature, with some studies showing restriction to have tumour-inhibitory effects, whereas others suggest excess to have adverse outcomes. We conducted a review of the published data to examine the accumulated evidence for involvement of dietary folate and/or methionine restriction or excess in intestinal tumour development in the Apc(Min/+) mouse model, which is genetically prone to develop such cancers. Thirteen publications were selected for evaluation based on the following inclusion criteria: (i) use of Apc(Min/+) mouse model; (ii) interventions using dietary folate and/or methionine; and (iii) primary outcome measures focused on intestinal tumour development. We found that nutritional modulation of folate and methionine was shown to have different effects on intestinal cancer in the Apc(Min/+) mouse, depending on the dosage, duration and timing of intervention, and interaction of the Apc(Min/+) genotype with other genetic factors affecting folate and DNA methylation metabolism. Although some studies showed that folate deficiency before tumorigenesis tended to increase risk of tumour formation, there are inconsistencies regarding whether excess folate post-weaning or after tumour initiation increases intestinal tumour burden. Altogether, the pooled data do not appear to indicate a difference in effect on intestinal tumour incidence between post-weaning diets that are folate deficient or folate adequate. The Apc(Min/+) mouse is a useful model for assessment of the impact of dietary folate on intestinal tumour development, but further research is required to understand the reasons for these inconsistencies amongst studies based on likely mechanisms, including modulation of nucleotide synthesis, DNA methylation, and chromosomal instability, which may affect the rate of cellular division and its control.

PMID: 25510540 DOI: 10.1111/jog.12648

α°-thalassemia is a well-known cause of hydrops fetalis in South-East Asia and can be detected in utero. We report a very rare case of thyrotoxic cardiomyopathy associated with hyperplacentosis secondary to α°-thalassemia-associated hydrops fetalis. A 22-year-old primigravida with microcytic anemia presented at 27 weeks' gestation with pre-eclampsia, hyperthyroidism and cardiac failure. Serum β-human chorionic gonadotrophin was markedly elevated and abdominal ultrasound revealed severe hydropic features and enlarged placenta. Serum β-human chorionic gonadotrophin, cardiac function and thyroid function tests normalized after she delivered a macerated stillbirth. Histopathology of the placenta showed hyperplacentosis. Blood DNA analysis revealed that both patient and husband have the α°-thalassemia trait. This case illustrates a very atypical presentation of α°-thalassemia-associated hydrops fetalis and the importance of early prenatal diagnosis of α-thalassemia in women of relevant ethnic origin with microcytic anemia so that appropriate genetic counseling can be provided to reduce maternal morbidity and the incidence of hydrops fetalis.

PMID: 29268718 DOI: 10.1186/s12885-017-3883-3

BACKGROUND: Chlorella vulgaris (ChV), a unicellular green algae has been reported to have anticancer and antioxidant effects. The aim of this study was to determine the chemopreventive effect of ChV on liver cancer induced rats by determining the level and expression of several liver tumour markers.
METHODS: Male Wistar rats (200-250 g) were divided into 4 groups according to the diet given: control group (normal diet), ChV group with three different doses (50, 150 and 300 mg/kg body weight), liver cancer- induced group (choline deficient diet + 0.1% ethionine in drinking water or CDE group), and the treatment group (CDE group treated with three different doses of ChV). Rats were killed at 0, 4, 8 and 12 weeks of experiment and blood and tissue samples were taken from all groups for the determination of tumour markers expression alpha-fetoprotein (AFP), transforming growth factor-β (TGF-β), M2-pyruvate kinase (M2-PK) and specific antigen for oval cells (OV-6).
RESULTS: Serum level of TGF-β increased significantly (p < 0.05) in CDE rats. However, ChV at all doses managed to decrease (p < 0.05) its levels to control values. Expressions of liver tumour markers AFP, TGF-β, M2-PK and OV-6 were significantly higher (p < 0.05) in tissues of CDE rats when compared to control showing an increased number of cancer cells during hepatocarcinogenesis. ChV at all doses reduced their expressions significantly (p < 0.05).
CONCLUSIONS: Chlorella vulgaris has chemopreventive effect by downregulating the expression of tumour markers M2-PK, OV-6, AFP and TGF-β, in HCC-induced rats.

PMID: 12495264

This study examined the effects of a tocotrienol-rich fraction (TRF) obtained from palm oil on the healing of aspirin-induced gastric mucosal lesions. Thirty-six male Sprague-Dawley rats (200-250 g) were randomly divided into three groups. Group I was fed a vitamin E-deficient diet (control), Group II was fed a vitamin E-deficient diet supplemented with tocopherol (300 mg/kg food) and Group III was fed a vitamin E-deficient diet supplemented with TRF (300 mg/kg food). After eight weeks, the control and treated groups received a single intragastric dose of 400 mg/kg body weight aspirin. The rats were killed 24 h after exposure to aspirin. Assessment of gastric lesions showed a lower gastric lesion index in the TRF (P = 0.0005) and tocopherol groups (P = 0.0008) compared to the control. The gastric malondialdehyde (MDA) content was also lower in the TRF (P = 0.025) and tocopherol groups (P = 0.025) compared to control. There were, however, no significant differences in the gastric lesion index and gastric MDA content between the TRF and tocopherol-fed groups. There were no significant differences in the adherent gastric mucous concentration and gastric acid concentration among all groups. We conclude that the TRF and tocopherol are equally effective in preventing aspirin-induced gastric lesions. The most probable mechanism is through their ability to limit lipid peroxidation, which is involved in aspirin-induced gastric lesions.

The nutritional situation in metropolitan Kuala Lumpur, with focus on squatters

Khor GL

Southeast Asian J Trop Med Public Health, 1992;23 Suppl 3:17-30.
PMID: 1342754

Kuala Lumpur is the capital city of Malaysia with an estimated population of 1.55 million. Approximately 12% of the population live in squatter settlements occupying about 7% of the city total area. The squatter settlements generally are provided with basic amenities such as piped water, toilet facilities and electricity. Health indicators for the overall population of Kuala Lumpur are better off than for the rest of the country; however, intra-city differentials prevail along ethnic and socio-economic lines. Malays and Indians have higher rates for stillbirths, and neonatal, infant and toddler mortality than the Chinese. The wide disparity in the socio-economic status between the advantaged and the poor groups in the city is reflected in the dietary practices and nutritional status of young children from these communities. The percentage of preschool children from urban poor households with inadequate intakes of calories and nutrients is two to three times higher than those from the advantaged group. Compared to rural infants, a lower percentage of urban infants are breastfed. A lower percentage of Malays from the urban advantaged group breastfed, compared with the urban poor group. The reversed trend is found for the Chinese community. Growth attainment of young children from the urban poor is worse than the urban advantaged, though better than the rural poor. Health and nutritional practices implications related to both undernutrition and overnutrition are discussed, to illustrate the twin challenges of malnutrition in the city.

Nutrients, 2016 Dec 14;8(12).
PMID: 27983628

Osteoporosis reduces the skeletal strength and increases the risk for fracture. It is an underdiagnosed disease in men. Annatto tocotrienol has been shown to improve bone structural indices and increase expression of bone formation genes in orchidectomized rats. This study aimed to evaluate the effects of annatto tocotrienol on biomechanical strength and calcium content of the bone in orchidectomized rats. Thirty three-month-old male Sprague-Dawley rats were randomly assigned to five groups. The baseline control (BC) group was sacrificed at the onset of the study. The sham-operated group (SHAM) received olive oil (the vehicle of tocotrienol) orally daily and peanut oil (the vehicle of testosterone) intramuscularly weekly. The remaining rats were orchidectomized and treated with three different regimens, i.e., (1) daily oral olive oil plus weekly intramuscular peanut oil injection; (2) daily oral annatto tocotrienol at 60 mg/kg plus weekly intramuscular peanut oil injection; (3) daily oral olive oil plus weekly intramuscular testosterone enanthate injection at 7 mg/kg. Blood, femur and tibia of the rats were harvested at the end of the two-month treatment period for the evaluation of serum total calcium and inorganic phosphate levels, bone biomechanical strength test and bone calcium content. Annatto-tocotrienol treatment improved serum calcium level and tibial calcium content (p < 0.05) but it did not affect femoral biomechanical strength (p > 0.05). In conclusion, annatto-tocotrienol at 60 mg/kg augments bone calcium level by preventing calcium mobilization into the circulation. A longer treatment period is needed for annatto tocotrienol to exert its effects on bone strength.
