    Restriction of antibiotic growth promoters (AGP) in Indonesia reduces broiler production due to bacterial diseases. Some poultry farmers have attempted to replace AGP with phytogenic compounds, such as tannin as an in-feed additive. Therefore, this study was carried out to investigate the effects of tannin administration on the production performance, viscera weight, and lipoprotein levels of tropically-raised broiler chickens. Cobb Strain broiler chicks aged one day were used in an experiment with a completely random design, three treatments, and four replicate pens, each containing nine birds. Three dietary treatments were assigned to the birds: basal diet (negative control), basal diet+0.03% Zn Bacitracyn (positive control), and basal diet+0.05% tannin for the starter phase of 1-21 days and the grower phase of 22-42 days, respectively. Tannin supplementation significantly increased the feed conversion ratio in all phases relative to the control group. Tannin supplementation in the diet significantly reduced daily feed intake during the grower phase, final body weight, carcass weight, intestine weight, liver weight, and total visceral weight, compared to the control group. Tannin had lower levels of aspartate aminotransferase but higher levels of low-density lipoprotein and alanine aminotransferase. Tannin addition in broiler diets might not improve growth performance and health. Therefore, it is not suggested as a substitute for AGPs in broiler diets.

    Blood lead levels of two ethnic groups (11 Chinese and 25 Malays) of workers in a factory manufacturing lead accumulator battery were studied. The mean adjusted (for environmental lead levels, age, exposure duration and stick-years of smoking by analysis of covariance) blood lead level of the Malays was 34.8 micrograms/dl as compared to 22.4 micrograms/dl for the Chinese. This difference was significant (p less than 0.02). Oral ingestion of lead, through eating of food with hands contaminated by lead compound, among the Malay workers was suggested as a possible cause for the difference in the mean blood lead levels. Preventive measures and recommendations to overcome the problem among this particular group of workers were discussed.

    BACKGROUND: Acute generalised exanthematous pustulosis (AGEP) is a rare, cutaneous reaction characterised by sudden onset of numerous, non-follicular, sterile pustules on oedematous erythematous skin, accompanied by fever and neutrophilia. AGEP is predominantly drug-induced. Skin lesions appear rapidly within 1-3 days of drug exposure and upon drug withdrawal, resolve rapidly within 15 days.

    OBJECTIVE: To determine the clinical characteristics, culprit drugs and outcome of patients with AGEP.

    METHODS: A retrospective note review of all AGEP patients seen from 2001-2015.

    RESULTS: Among 21 AGEP patients, 76% were Malays, 9.5% Chinese, 9.5% Indians, and 5% Iban. Sixteen were females and 5 were males. Median age of patients was 40 years (IQR: 26). The main culprit drug was amoxicillin (10 cases), followed by cloxacillin (three cases), phenytoin (two cases) and one case each of carbamazepine, sulphasalazine, allopurinol, cephalexin, ceftriaxone, celecoxib and herbal product. The median time from drug initiation to onset of AGEP was 3 days (IQR: 5.5). Fever was documented in 52.4 %, mucosal involvement 9.5%, purpura 4.7% and blisters 4.7%. Neutrophilia was observed in 63.6% of patients and eosinophilia in 28.5%. While most patients required admission (67%), all achieved complete recovery within 15 days without any sequela.

    CONCLUSIONS: AGEP predominantly affects Malay females in this study. The most common culprit drug was amoxicillin. Our patients exhibited the classic clinical manifestations of AGEP and confirmed the generally benign nature of this reaction upon drug withdrawal. Although the overall prognosis is good, prompt diagnosis of AGEP is important because drug withdrawal is the mainstay therapy.

    BACKGROUND/OBJECTIVES: Dietary triacylglycerols containing palmitic acid in the sn-2 position might impair insulin release and increase plasma glucose.

    SUBJECTS/METHODS: We used a cross-over designed feeding trial in 53 healthy Asian men and women (20-50 years) to test this hypothesis by exchanging 20% energy of palm olein (PO; control) with randomly interesterified PO (IPO) or high oleic acid sunflower oil (HOS). After a 2-week run-in period on PO, participants were fed PO, IPO and HOS for 6 week consecutively in randomly allocated sequences. Fasting (midpoint and endpoint) and postprandial blood at the endpoint following a test meal (3.54 MJ, 14 g protein, 85 g carbohydrate and 50 g fat as PO) were collected for the measurement of C-peptide, insulin, glucose, plasma glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1, lipids and apolipoproteins; pre-specified primary and secondary outcomes were postprandial changes in C-peptide and plasma glucose.

    RESULTS: Low density lipoprotein cholesterol was 0.3 mmol/l (95% confidence interval (95% CI)) 0.1, 0.5; P<0.001) lower on HOS than on PO or IPO as predicted, indicating good compliance to the dietary intervention. There were no significant differences (P=0.58) between diets among the 10 male and 31 female completers in the incremental area under the curve (0-2 h) for C-peptide in nmol.120 min/l: GM (95% CI) were PO 220 (196, 245), IPO 212 (190, 235) and HOS 224 (204, 244). Plasma glucose was 8% lower at 2 h on IPO vs PO and HOS (both P<0.05).

    CONCLUSION: Palmitic acid in the sn-2 position does not adversely impair insulin secretion and glucose homeostasis.

    BACKGROUND: Smoking has always been a huge problem in Malaysia and its surrounding nations. The purpose of this study was to determine the prevalence of cigarette smoking and to identify the influencing factors associated with smoking habits among adolescents.

    MATERIALS AND METHODS: This cross-sectional study was carried out on 226 respondents, using a questionnaire which had 4 sections: socio-demographic data, personal information, family information and social information. Data was analyzed using SPSS® version 16. For categorical variables, comparisons were made using Chi-square and for numerical variables a t-test was performed.

    RESULTS: The current smoker prevalence rate was 20.8% which showed a significant association between smoking and individual factors: level of knowledge on the effects of smoking (p < 0.05), significant association was seen between smoking and marital status of parents, smoking status of male siblings and various other aspects of the individuals themselves.

    CONCLUSIONS: Concerted efforts involving various parties should be taken to curb or prevent this problem or the number of teenage smokers in the country will increase. This in the long run will invite problems to the well being of the adolescents themselves, their families, community and the nation as a whole.

    A simple yet useful criterion based on external markings and/or number of dorsal spines is currently used to differentiate two congeneric archer fish species Toxotes chatareus and Toxotes jaculatrix. Here we investigate other morphometric and meristic characters that can also be used to differentiate these two species. Principal component and/or discriminant functions revealed that meristic characters were highly correlated with pectoral fin ray count, number of lateral line scales, as well as number of anal fin rays. The results indicate that T. chatareus can be distinguished from T. jaculatrix by having a greater number of lateral line scales, a lower number of pectoral fin rays, and a higher number of anal fin rays. In contrast, morphometric discriminant analyses gave relatively low distinction: 76.1% of fish were ascribed to the correct species cluster. The observed morphometric differences came from the dorsal and anal spines lengths, with T. chatareus having shorter dorsal and longer anal spines than T. jaculatrix. Overall, meristic traits were more useful than morphometrics in differentiating the two species; nevertheless, meristics and morphometrics together provide information about the morphological differentiation between these two closely related archer fishes.

    In primary care, chest X-rays are commonly performed to assess patients presenting with a prolonged
    cough. However, the extent to which the flms are accurately interpreted depends on the skill of the
    doctors. Doctors with insufcient experience may miss an exact diagnosis when evaluating a flm,
    especially in patients with nonspecifc symptoms, such as in the case discussed in this paper.

    INTRODUCTION: Influenza outbreak causes high economic burden to Malaysia and other countries in South East Asia. Scientists have found a relatively new way to detect influenza outbreaks early thus reducing the burden of disease by early intervention. This new technology is a social network information system which uses Facebook or Twitter data to detect potential influenza cases. Such system is good to be developed by the Malaysian government as it can detect influenza outbreaks three weeks earlier than the normal pathway. However, to implement this we require good evidence that the development will be accepted by potential users.

    OBJECTIVE: This study was looking at the acceptance towards using social network information system among public health workers.

    MATERIALS AND METHOD: This study was done on 205 Malaysian One Health University Network (MyOHUN) members through email and physical survey.

    RESULTS: Results show that 62.4% public health workers accepted the use technology. The acceptance was shown to be associated with performance expectancy (p<0.05). However, unlike the very famous Unified Theory of Acceptance and Use of Technology (UTAUT) model, the acceptance of social network information system was not associated with effort expectancy, social factors, facilitating conditions and socio-demographic factors. Therefore, it is suggested that social network information system be developed by the authorities in Malaysia, and be developed in a way that the system could strongly increase performance in detection of outbreak earlier than the current normal pathways. As such the system to be accepted and used, it must be sensitive, specific and be able to detect influenza outbreak early CONCLUSION: The development of social network information system is feasible as it is highly accepted and it's potential to improve early detection of influenza outbreak.

    Recent breakthroughs in G protein-coupled receptor (GPCR) crystallography and the subsequent increase in number of solved GPCR structures has allowed for the unprecedented opportunity to utilize their experimental structures for structure-based drug discovery applications. As virtual screening represents one of the primary computational methods used for the discovery of novel leads, the GPCR-Bench dataset was created to facilitate comparison among various virtual screening protocols. In this study, we have benchmarked the performance of Molecular Mechanics/Poisson-Boltzmann Surface Area (MM/PBSA) in improving virtual screening enrichment in comparison to docking with Glide, using the entire GPCR-Bench dataset of 24 GPCR targets and 254,646 actives and decoys. Reranking the top 10% of the docked dataset using MM/PBSA resulted in improvements for six targets at EF1% and nine targets at EF5%, with the gains in enrichment being more pronounced at the EF1% level. We additionally assessed the utility of rescoring the top ten poses from docking and the ability of short MD simulations to refine the binding poses prior to MM/PBSA calculations. There was no clear trend of the benefit observed in both cases, suggesting that utilizing a single energy minimized structure for MM/PBSA calculations may be the most computationally efficient approach in virtual screening. Overall, the performance of MM/PBSA rescoring in improving virtual screening enrichment obtained from docking of the GPCR-Bench dataset was found to be relatively modest and target-specific, highlighting the need for validation of MM/PBSA-based protocols prior to prospective use.

    BACKGROUND: Older persons with diabetes are the major demographic of diabetic patients followed up in primary health clinics. Despite their increasing age and morbidities, they are still being managed strictly towards good sugar control in order to achieve the ideal HbA1c level without taking their quality of life into consideration. This study aimed to determine the prevalence in the use of antidiabetic drugs among older persons with diabetes and its association with their quality of life.

    METHODOLOGY: A cross-sectional study was conducted among 269 older persons with diabetes in all government health clinics in Kuantan using Diabetes Quality of Life questionnaire. SPSS version 23 was used for the statistical analysis.

    RESULTS: Majority of the respondents were females (61%), Malays (84.8%), pensioners (54.3%) with education up to primary school (52%) and are staying with family members (93.7%). Most of the patients were on two antidiabetic agents (48%) followed by a single antidiabetic agent (32%). Despite the risk of hypoglycaemia, 0.4% of them are on glibenclamide. The use of insulin is still common among 21% of them that are on intermediate-acting insulin, 15.6% on premixed insulin and 7.8% on short-acting insulin. Those taking a higher number of antidiabetic agents were found to be associated with poorer quality of life (p=0.001) compared to those taking one or two antidiabetic medications. Those on insulin also have significantly poorer quality of life score (p=0.012).

    CONCLUSION: Despite aiming for controlled diabetes, older persons suffer poor quality of life with further intensification of their antidiabetic medications according to the guidelines. This includes the complexity of insulin usage and polypharmacy, which contribute to the low quality of life score.

    Background The incidence of osteoporosis in Malaysia is increasing due to a fast-ageing population. Because of its silent nature, various osteoporosis risk assessment tools exist to detect high-risk patients and facilitate referrals for bone mineral density measurements. As an accessible point of contact, community pharmacists would benefit from the utilization of these tools and familiarity with guideline recommendations for osteoporosis screening. Aim This study aimed to investigate the awareness of osteoporosis risk assessment tools, practice behaviour towards osteoporosis, and knowledge of guideline recommendations among community pharmacists in the Klang Valley, Malaysia. Setting Community pharmacies. Methods This study was a cross-sectional study which sampled 284 community pharmacists practicing in the Klang Valley, using a stratified sampling approach. The study was conducted using a self-administered questionnaire which was divided into three sections: demographic data, knowledge of osteoporosis risk assessment tools and guideline recommendations, and practice behaviour towards osteoporosis. Practice behaviour was assessed with 15 items using a 5-point Likert scale. Main outcome measure. Proportion of respondents aware of osteoporosis risk assessment tools and respondent knowledge on guideline recommendations for osteoporosis screening. Results A total of 284 community pharmacists participated in the study. 84.1% of the respondents were aware of at least one risk assessment tool. However, only a small proportion of pharmacists (14.9%) regularly used these tools in their practice. Respondents perceived these tools to be relevant and beneficial, but perception towards their accessibility, ease-of-use, and administration time was mixed, suggesting unfamiliarity. Respondents preferred to conduct clinical assessments based on risk factors, with respondents identifying a mean of 10.1 ± 3.4 out of 15 risk factors. However, several clinically relevant risk factors were frequently unidentified. Knowledge of guideline recommendations among respondents was low. Conclusion There is some awareness of osteoporosis risk assessment tools but use in practice remains low among community pharmacists in Malaysia. There is potential to increase the use of these tools and knowledge of recommendations for osteoporosis screening and referral among community pharmacists.

    OBJECTIVES: To identify factors influencing the decisions of Malaysian first-year pharmacy undergraduate students in private higher education when choosing to pursue a degree in pharmacy as well as their choice of private university.

    METHODS: This cross-sectional study employed a validated, self-administered questionnaire which was administered to 543 first-year pharmacy students from nine different private universities. Factor analysis was utilised to extract key factors from the responses. Descriptive and inferential statistics were used to analyse the data.

    KEY FINDINGS: Eight factors motivating students' decision to study pharmacy emerged from the responses, accounting for 63.8% of the variance observed. Students were primarily motivated by intrinsic interests, with work conditions and profession attributes also exerting significant influence. In terms of choice of private university, nine factors were identified, accounting for 73.8% of the variance observed. The image of the school and university were most influential factors in this context, followed by university safety, programme attributes and financial factors.

    CONCLUSIONS: First-year pharmacy students in the private higher education sector are motivated by intrinsic interest when choosing to study pharmacy over other courses, while their choice of private university is influenced primarily by the image of the school and university.

    AIM: To investigate the number of roots and root canal configurations using two coding systems and the root canal diverging and merging levels in extracted maxillary premolars in an Egyptian subpopulation using cone beam computed tomography (CBCT).

    METHODOLOGY: A total of 700 maxillary premolars were examined using CBCT in an Egyptian subpopulation. The number of roots was identified, and root canal configurations were classified according to Vertucci's classification and a new system for classifying root and canal morphology. In addition, the position where roots bifurcated and the levels where canals merged or diverged were identified. Fisher's exact test and independent t-test were used for statistical analysis, and the level of significance was set at 0.05 (P = 0.05).

    RESULTS: More than half of maxillary first premolars were double-rooted, and the majority of maxillary second premolars were single-rooted (P

    BACKGROUND: Potentially inappropriate medications (PIMs) in older adults are detrimental to both clinical outcomes and health care costs, with their prominence set to increase in tandem with a fast-growing ageing population. Beers Criteria is one of the most commonly used guidelines that lists specific PIMs. Community pharmacists would therefore benefit from knowledge of Beers Criteria in detecting PIMs in primary care. This study therefore investigates the awareness of Beers Criteria and knowledge of PIMs among community pharmacists in the Klang Valley, Malaysia.

    METHODS: The study was conducted using a self-administered questionnaire. Knowledge of PIMs was assessed using 10 clinical vignettes based on the 2015 Beers Criteria. Practice behaviour towards older customers was assessed using 10 items with a 5-point Likert scale. Descriptive and inferential statistics were used to analyse the data.

    RESULTS: A total of 277 community pharmacists participated in the study. Only 27.1% of the pharmacists were aware of Beers Criteria, and of these, only 37.3% were aware of the latest 2015 update. The respondents demonstrated moderate knowledge of PIMs with a mean total score of 5.46 ± 1.89 out of a maximum of 10. Pharmacists who were aware of Beers Criteria had significantly higher scores (6.31 vs 5.14, P

    INTRODUCTION: Sarcomas of the Ewing family of tumours are aggressive neoplasms occurring in bone and soft tissue of mostly children and young adults. It usually affects male more than female with peak incidence 10 to 15 years of age, and rarely encountered in adults especially in more than 40 years old. It is an aggressive, rare tumour with a tendency toward recurrence after resection and early metastasis.

    CASE REPORT: We reported a rare case of Ewing Sarcoma in a 62-year-old woman who had an unusual clinical presentation. She had right painless buttock swelling only for a month. Magnetic resonance imaging (MRI) revealed soft tissue sarcoma originated from right gluteal muscle. The diagnosis of Ewing sarcoma (ES) was made in a limited diagnostic material in an initial tru-cut biopsy, followed by an excision supported by immunohistochemistry (IHC) and Fluorescent In-Situ Hybridization (FISH).

    DISCUSSION: The purpose of this study is to document ES in an adult woman and its diagnostic challenges in histopathologic perspective.

    OBJECTIVES: To determine the prescribing patterns and identify potentially inappropriate prescribing practices among general practitioners in the private primary care sector by analysing a large electronic health insurance claims database.

    METHODS: Medical claims records from February 2019 to February 2020 were extracted from a health insurance claims database. Data cleaning and data analysis were performed using Python 3.7 with the Pandas, NumPy and Matplotlib libraries. The top five most common diagnoses were identified, and for each diagnosis, the most common medication classes and medications prescribed were quantified. Potentially inappropriate prescribing practices were identified by comparing the medications prescribed with relevant clinical guidelines.

    KEY FINDINGS: The five most common diagnoses were upper respiratory tract infection (41.5%), diarrhoea (7.7%), musculoskeletal pain (7.6%), headache (6.7%) and gastritis (4.0%). Medications prescribed by general practitioners were largely as expected for symptomatic management of the respective conditions. One area of potentially inappropriate prescribing identified was inappropriate antibiotic choice. Same-class polypharmacy that may lead to an increased risk of adverse events were also identified, primarily involving multiple paracetamol-containing products, non-steroidal anti-inflammatory drugs (NSAIDs), and antihistamines. Other areas of non-adherence to guidelines identified included the potential overuse of oral corticosteroids and oral salbutamol, and inappropriate gastroprotection for patients receiving NSAIDs.

    CONCLUSIONS: While prescribing practices are generally appropriate within the private primary care sector, there remain several areas where some potentially inappropriate prescribing occurs. The areas identified should be the focus in continuing efforts to improve prescribing practices to obtain the optimal clinical outcomes while reducing unnecessary risks and healthcare costs.
