Background: The PLASMIC score is a convenient tool for predicting ADAMTS13 activity of ＜10%.Lactate dehydrogenase (LDH) is widely used as a marker of haemolysis in thrombotic thrombocytopenic purpura (TTP) monitoring, and could be used as a replacement marker for lysis. We aimed to validate the PLASMIC score in a multi-centre Asia Pacific region, and to explore whether LDH could be used as a replacement marker for lysis. Methods: Records of patients with thrombotic microangiopathy (TMA) were reviewed. Patients’ ADAMTS13 activity levels were obtained, along with clinical/laboratory findings relevant to the PLASMIC score. Both PLASMIC scores and PLASMIC-LDH scores, in which LDH replaced traditional lysis markers, were calculated. We generated a receiver operator characteristics (ROC) curve and compared the area under the curve values (AUC) to determine the predictive ability of each score. Results: 46 patients fulfilled the inclusion criteria, of which 34 had ADAMTS13 activity levels of ＜10%. When the patients were divided into intermediate-to-high risk (scores 5‒7) and low risk (scores 0‒4), the PLASMIC score showed a sensitivity of 97.1% and specificity of 58.3%, with a positive predictive value (PPV) of 86.8% and negative predictive value (NPV) of 87.5%. The PLASMIC-LDH score had a sensitivity of 97.1% and specificity of 33.3%, with a PPV of 80.5% and NPV of 80.0%. Conclusion Our study validated the utility of the PLASMIC score, and demonstrated PLASMIC-LDH as a reasonable alternative in the absence of traditional lysis markers, to help identify high-risk patients for treatment via plasma exchange.

In this paper, we provide guidance to clinicians who care for infants born to mothers with suspected/confirmed COVID-19 during this current pandemic. We reviewed available literature and international guidelines based on the following themes: delivery room management; infection control and prevention strategies; neonatal severe acute respiratory syndrome coronavirus 2 testing; breastfeeding and breastmilk feeding; rooming-in of mother-infant; respiratory support precautions; visiting procedures; de-isolation and discharge of infant; outpatient clinic attendance; transport of infant; and training of healthcare staff. This guidance for clinical care was proposed and contextualised for the local setting via consensus by members of this workgroup and was based on evidence available as of 31 July 2020, and may change as new evidence emerges.

Introduction: The incidence of angiotensin-converting enzyme inhibitors (ACEi)-induced cough has been reported between 5% and 30% but is unknown in Malaysia. This study aimed to determine the incidence of ACEi-induced cough and its associated factors in a public primary care clinic in Malaysia. Methods: A retrospective review of electronic medical records of patients who were initiated ACEi between January 1, 2015, and December 31, 2015, and reviewed until July 31, 2016. A total of 1,091 patients were newly prescribed ACEi, and 394 patients were eligible for this study. We excluded patients who defaulted follow-ups with no further clinic visits before July 31, 2016, were transferred to the clinic without the recorded date of ACEi initiation, were transferred to other clinics during the study period, were followed up at other clinics and attended the study clinic for a short period, or were given only a stat dose of ACEi. Results: Among the 394 patients initiated on ACEi, 225 (57.1%) were male, 369 (93.7%) were Malay, 376 (95.4%) had hypertension, and 192 (48.7%) had diabetes. The incidence of ACEi-induced cough was 24.1%, and 42 (10.7%) patients developed cough on the day of therapy initiation. There was no association between age, gender, ethnicity, type of ACEi, and cough. Conclusion Approximately one quarter of patients developed cough after ACEi initiation, and approximately half of them developed cough within 1 week of ACEi initiation. Doctors should consider early follow-up for patients initiated on ACEi therapy to ensure adherence, quality of life, and minimise unnecessary treatment.

Radiation thyroiditis resulting from radioactive iodine-131 treatment for Graves' disease is an uncommon complication. Although a majority of patients are asymptomatic or manifest mild symptoms that can be managed conservatively, published literature describing severe radiation thyroiditis resulting in significant morbidity is lacking. We herein report on six patients with severe radiation thyroiditis that resulted in hospitalisation, including an unusual complication of myopericarditis.

Objectives: To evaluate study designs and citation counts of original research published in the Medical Journal of Malaysia (MJM). Methods: The bibliographic data of the MJM for the period 1980-2016 were retrieved from PubMed and analysed using Endnote bibliographic software. Study designs of original journal articles were analysed according to whether the articles were diagnostic study, prognostic study or clinical trial (collectively known as “evidence papers”). The citation counts of the original articles and case reports for the period 2012-2016 were compared in a sub-study using a case-control design. Results: A total of 3952 MJM journal items were retrieved from PubMed for the period 1980-2016; of these, 58.9% were original articles and 29.5% were case reports. Among the original articles, 14.6% were “evidence papers”; 2.3% were diagnostic studies, 7.7% were prognostic studies, 4.6% were clinical trials. In the study period 2012-2016, “other types of original articles” had statistically significantly more citations than case reports. However, there is no difference between “evidence papers” and case reports. Conclusion Our analysis shows the distribution of the types of articles appearing in the MJM for the period of study and serves as a reference for improving citations counts in the local context.

Introduction: A recently published meta-analysis showed that each additional serving of rice increased risk of type 2 diabetes mellitus (DM) by an alarming 11%. We investigated whether this phenomenon is seen in the Malaysian population by studying the effect of rice intake and added sugar consumption on fasting plasma glucose (FPG) and fasting triacylglycerol (TAG). Methods: Ninety subjects (60 females, 30 males, aged 30-70 years), adequate to detect a weak-to-moderate Pearson correlation of r=0.26 at a=0.05 and power= 0.80, were recruited by convenience sampling from six communities in the Klang Valley, Malaysia. Fasting blood samples were collected by finger-prick and analysed for FPG (AccuCek, Roche) and TAG (Accutrend, Roche). Macronutrient intakes, including rice, were obtained by a single interview using a previously-evaluated food frequency questionnaire (FFQ) and quantitated as grams by the DietPLUS V2 programme. Added sugar intakes by subjects were estimated using an Added Sugar Intake excel programme. Results: Rice contributed to 85% of dietary carbohydrates, accounting for 41.8 % kcal of the average 1750- kcal diet. Rice intakes or added sugar consumption did not have a significant correlation (p>0.05) with FPG nor fasting TAG. Added sugar consumption, which averaged 44g/person/day (5% kcal) was markedly lower than the 137g/person/day reported elsewhere for the Malaysian population. Conclusion: High consumption of rice as a risk factor of type 2 DM was not indicated in the present study. Since white rice consumption varied 10-fold in the present subjects, the reduction in daily intake of this staple food represents a feasible option for cutting back on calorie intake for overweight or obese individuals.

Aims: Bacteria on chicken egg surfaces can be potential sources of food borne diseases. The aim of this study was to determine the prevalence of E. coli, Salmonella and enterococci on the surface of conventional broiler eggs, “Kampung” chicken eggs and carrying trays and to determine the antimicrobial resistant profile of these isolates. Methodology and results: Conventional broiler eggs, “Kampung” chicken eggs and carrying trays were sampled randomly from nine wet markets in Selangor, Malaysia. The surface of the eggs and carrying trays were swabbed and E. coli, Salmonella and enterococci were isolated using selective agars. Antimicrobial susceptibility testing (AST) was performed on the isolates against different antimicrobials via disk diffusion test. A large proportion of E. coli isolates (>50% of isolates from conventional broiler eggs and “Kampung” chicken eggs) was resistant to chloramphenicol and tetracycline whereas enterococci (>60% of isolates from conventional broiler eggs and “Kampung” chicken eggs) isolates were resistant to tetracycline and erythromycin. Salmonella isolates were found to be susceptible to all of the antimicrobials tested except for tetracycline. There was also presence of isolates showing multiple resistances in this study. E. coli isolates (8.8%) from the surface of “Kampung” chicken eggs were resistant against 10 different antimicrobials whereas 17.8% of the enterococci isolates from the surface of “Kampung” chicken eggs were resistant to 11 different antimicrobials. Conclusion, significance and impact of study: The presence of multiple-antimicrobial resistant bacteria especially on the surface of “Kampung” chicken eggs that are ready to be sold to consumers is a serious concern. However, further study has to be conducted to determine the ultimate source of the bacterial contamination before specific food safety measures can be introduced.

Background: The public health issue of consuming groundwater is a major concern because people often extract groundwater directly from the aquifers either through wells or boreholes without treating it with any form of filtration system or chlorine disinfection. Based on the Malaysian National Drinking Water guidelines the current study was designed to provide a better understanding on the variable factors that are influencing the quality of well-water in an urbanised village in Malaysia. Well water quality assessment of heavy metals, chemicals, microbial and physical parameters were carried out for Sungai Buloh Village in the Klang Valley to ensure it was safe for human consumption. Materials and Methods: Water samples were collected from wells at four sites (Sites A,B,C,D), a river and a tap inside a house in Sungai Buloh village. Soil was sampled from the riverbed and area surrounding the wells. Samples were collected every two months over a one year duration from all sites. The water samples were processed and examined for viruses, coliforms and protozoa as well as for heavy metal contaminants. Results: The turbidity and colour ranged in the average of 0.57-0.13 Nephelometric Turbidity (NTU) and 4.16- 5.00 Total Conjunctive Use (TCU) respectively for all sites except Site C. At Site C the turbidity level was 2.56 ± 1.38 NTU. The well-water was polluted with coliforms (1.2 to 2.4 x 10 3 CFU/100 ml) in all sites, E. coli (0.12 - 4 x 10 2 CFU/100 ml CFU/ 100 ml) and Cryptosporidium oocysts (0.4 cysts/100 ml). All the heavy metals and chemical parameters were within the Malaysian Guidelines’ limits except manganese. The average pH ranged from 5.44 - 6.62 and the temperature was 28 ºC. Conclusion: In summary, the well water at Sungai Buloh is considered unsafe for consumption due to pollution. Therefore the major thrust will be to provide better quality of drinking water to the residents of the village.

Adequate nutrition is important for mothers and their offspring during and after birth. This cross sectional study was conducted to determine nutritional status and nutritional knowledge of pregnant women from two selected private hospitals in Klang Valley, Malaysia. A total of 236 Malay pregnant women aged between 20 to 45 years old (mean age 31+5 years) were recruited through convenient sampling method. Socio-demographic data, nutritional knowledge and a 24-hours diet recall were obtained through a self-administered questionnaire. Anthropometric and haemoglobin data were obtained from the antenatal records in the respective hospitals. The percentages of participants who were underweight, normal, overweight and obese before pregnancy were 12.7%, 55.1%, 25.0% and 7.2% respectively. Among those who were obese before pregnancy, a total of 59.7% had inadequate weight gain, 24.6% gained adequate weight and 15.7% gained excessive gestational weight. About 33.5% of subjects were anaemic (Hb < 11.0g/dL). The mean daily energy intake of the participants was 1748 ± 526 kcal which was 76% of RNI. Calcium (73% of RNI), folic acid (36% of RNI), niacin (89% of RNI) and vitamin D (40% of RNI). The nutritional knowledge level of subjects was moderate (51.9 ± 13.8%). Lower monthly household income (p < 0.001), educational level (p < 0.001) and gestational stage (p < 0.05) of participants were associated with a lower nutritional knowledge level. Nutritional knowledge score was positively correlated with gestational weight gain (r = 0.166, p < 0.05) and haemoglobin level (r = 0.200, p < 0.05). Subjects who claimed practising food taboos had higher nutritional knowledge score (54.9 ± 12.5%) than those who did not (49.9 ± 14.4%)(p < 0.05). A comprehensive nutrition education should be integrated in the antenatal classes to improve nutritional status of pregnant women
