Nurses’ job performance is defined as the effectiveness of a person in carrying out his or her duties related to patient care. Aim of this study is to measure job performance among nurses in a tertiary hospital and its associated factors. A cross-sectional study was conducted among nurses selected from four departments, which were Obstetrics & Gynecology (O&G), medical, surgical and Cardiac Care Unit (CCU)/High Dependency Unit (HDU). A Malay validated Six-Dimension Scale of Nursing Performance (6-DSNP) questionnaire was used to measure job performance. Nurses who have one child more compared to other nurses had significantly lower total mean score of job performance by -0.06 (95% CI 0.11, 0.01). Nurses working in medical department [adj.β=0.16 (95% CI 0.01, 0.30)] and CCU/HDU [adj.β= 0.33(95% CI: 0.17, 0.50)] had significantly higher total mean scores of jobs performance compared to O&G department. Effective strategies and re-examining work conditions are imperative for better job performance.

Aims: Rice blast disease caused by Pyricularia oryzae is one of the major biotic diseases of rice in Sarawak, Malaysian Borneo. This study aims to isolate and characterize rice blast fungus obtained from infected leaf collected from four different divisions in Sarawak, viz, Miri, Serian, Sri Aman, and Kuching. Methodology and results: Twelve succeeded isolates were pre-identified as P. oryzae by morphological characteristics of spores, followed by verification through (internal transcribed spacer) ITS sequencing. The isolates were evaluated for morphological characteristics, growth rate and sporulation rate, which were grown on two types of media, (filtered oatmeal agar) FOMA and (potato dextrose agar) PDA. Morphological characterization showed that the colony surface of the different isolates varied from smooth and fluffy to rough and flattened mycelia; some were with the present of concentric rings, and some with aerial mycelia. The growth rate and sporulation rate of each isolate varied based on types of media used. Most of the isolates grew faster on PDA than on FOMA but produced higher number of spores on FOMA as compared to PDA. Conclusion, significance and impact of study: This preliminary study showed that there were variations observed based on morphological and physiological characterization for the different isolates collected in Sarawak, Malaysian Borneo. This study is the first step towards understanding variation in the population of P. oryzae from Sarawak.

The aim of this study was to determine the polyphenol content and antioxidant activities in commercialized date and pomegranate concentrates that are available in local market. A total of seven samples comprised of two brands of date concentrates (D1 and D2) and five brands of pomegranate concentrates (P1, P2, P3, P4, and P5) have been analyzed for their polyphenol content and antioxidant activity. The Folin-Ciocalteu assay was used to determine the polyphenol content (TPC) of the samples while 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and Ferric Reducing Antioxidant Power (FRAP) assays were used to determine the antioxidant activity. The results showed the commercialized date concentrate D2 contained the highest TPC (1243.00 ± 67.00 mg GAE/100 ml) and antioxidant activity using FRAP assay (2.67 ± 0.01 mmol TE/100 ml). Date concentrate D1 showed the highest antioxidant activity using DPPH assay (0.39 ± 0.02 mmol TE/100 ml). The pomegranate concentrate P5 showed the highest reading for TPC (3260.10 ± 428.70 mg GAE/100 ml), DPPH (1.61 ± 0.05 mmol TE/100 ml) and FRAP assays (20.98 ± 0.42 mmol TE/100 ml). As a conclusion, the studied commercial date and pomegranate concentrates available in the local market contained high polyphenol and antioxidant contents although the content levels were different from one brand to another. Further study is needed to identify the causes of this distinction. The results of this study could help the consumers to make a better selection of commercialized date and pomegranate concentrates that are available in local market in term of polyphenol content and antioxidant activity.

Visual impairment among children can be serious without early intervention. This study was conducted to determine prevalence of visual impairment causes among preschool children. Twenty one kindergartens were randomly selected for vision screening. The screening module consist of visual acuity test, cover test, Hirschberg’s test, exsternal ocular asessment and ophthalmoscopy. Preschool children who failed the vision screening were referred for further assessment. Four hundred and seventy nine preschool children with an average age of 5.30 ± 0.69 years old participated in the vision screening program. Of those 43 children who failed the vision screening, 32 (6.7%) children were confirmed to have some form of visual impairment, while 8 children were normal. Three children were excluded from the study because the children did not cooperate for further assessment. The main cause of visual impairment among preschool children was refractive error (5.8%). Other causes were amblyopia (1.3%), strabismus (1.0%) and ocular abnormalities (0.8%). In conclusion early detection of visual impairment through vision screning and early optometric intervention is very important to be conducted among preschool children so that visual impairment can be reduced.

The inhibitory effect of phytate on the bioavailability of iron, zinc and calcium was determined by measuring their molar ratios. A total of 29 food samples consisting of 12 rice and rice products, 5 wheat and wheat products, 5 grains and cereal based products and 7 different popular varieties of cooked rice and rice products were selected. The phytate content was analysed using anion-exchange chromatography whereas mineral contents were analysed using atomic absorption spectrophotometry(AAS). One-way ANOVA test was used to statistically analyse the mean difference between the phytate and mineral contents between the food group samples. In general, results show that cooked products have lower content of phytate and minerals as compared to raw products. This could be due to the influence of the cooking method on phytate and mineral content in the food. Based on one-way ANOVA test, there were no significant difference in phytate and zinc content between four food groups (p >0.05). Significant differences were found only in iron and calcium content (p <0.05). Of the 29 food samples, 25 food samples had a phytate/iron molar ratio > 1, 5 food samples had a phytate/zinc molar ratio > 15 and 23 food samples had a phytate/ calcium molar ratio of 0.24. These results show that although many of the food samples analysed had high mineral content, the high phytate content may impair the bioavailability of the mineral in the body.

Aims: Bakanae disease on rice has been widely distributed in all countries where rice is grown commercially, especially in Asian countries including Malaysia. As an alternative measure in controlling Fusarium fujikuroi, two approaches have to be adapted i.e. by using resistant varieties and biocontrol agents as reported in the present study. Methodology and results: A total of 31 Malaysian rice varieties were used in screening and results showed that variety MR211 was the most susceptible and MR220 was slightly susceptible. Out of 60 isolates of Trichoderma harzianum isolated from soils in Malaysia and tested against the pathogen under in vitro condition, 13 isolates showed high percentage of inhibition (PIRG > 60%). All isolates of T. harzianum showed that the PIRGs were significantly different at p≤0.05 with those of control plates. Conclusion, significance and impact of study: Biocontrol agent and resistant variety are better alternative for controlling plant diseases. We found a variety MR220 was slightly susceptible, but none of tested varieties is resistant towards pathogen of bakanae disease. T. harzianum has the ability to inhibit the growth of F. fujikuroi (T3068P) under in vitro condition. The findings of the Malaysian susceptible/resistant variety and potential T. harzianum isolate as a biocontrol agent of bakanae are important for future tests in the plant house and field trials.

Infective endocarditis (IE) is a disease that is rare but potentially fatal and challenging to diagnose. A 28-year-old man with sickle cell trait and a history of intravenous drug use presented with abdominal pain and hematuria mimicking a surgical abdomen. The preliminary diagnosis was cholecystitis or perforated viscus. The chest radiograph was indicative of pulmonary septic emboli. Computed tomography was initially thought to show pyelonephritis, but further review of images revealed renal infarct. The patient was found to have endocarditis which resulted in an embolic renal infarct. The patient recovered remarkably well after 60 days of intravenous antibiotics. This case demonstrates that a surgical abdomen may also be a sign of endocarditis, and multiple imaging studies may be required to confirm the diagnosis. In patients such as intravenous drug users with an increased risk of IE, unexplained flank pain should raise a suspicion of acute renal infarction.

A total of 25 strains of Fusarium species that belong to F. fujikuroi (a pathogen of bakanae disease), F. proliferatum, F.sacchari, F. subglutinans and F. verticillioides were isolated from rice plants showing typical bakanae symptoms in Malaysia and Indonesia and screened for their secondary metabolites. The objectives of the studies were to determine the physiological variability based on production of moniliformin (MON), fumonisin (FB1), gibberellic acid (GA3) and fusaric acid (FA) as well as to ascertain the mating populations (MPs) within the Gibberella fujikuroi species complex based on their ability to produce perithecia and viable ascospores. Production of GA3 could be used to separate F. fujikuroi that belongs to MP-C from other species. In crosses with seven standard testers of MPs, 76% of strains could be assigned to at least one of the G. fujikuroi species complex namely MP-A (G. moniliformis), MP-B (G. sacchari), MP-C (G. fujikuroi) and MP-D (G. intermedia). Single strain (M3237P) that was assigned as MP-C, and has also been identified morphologically as F. fujikuroi was also crossed-fertile with MP-D tester. The secondary metabolites profiles and the presence of MP-A, MP-B, MP-C and MP-D strains on samples of bakanae-infected rice plants are new records in Malaysia.

Aim: Multi-drug resistant bacteria have become a global issue. Drug-resistant bacteria can be found in humans, animals, food and environmental sources. Staphylococcus aureus is one of many bacteria species known for its antimicrobial resistance. The current study is conducted to determine the antimicrobial resistance profiles of S. aureus isolated from raw chicken meat samples in Kota Bharu, Kelantan. Methodology and results: Fifty raw and fresh chicken meat samples were purchased from 3 different wet markets in Kota Bharu, Kelantan and were transported to the laboratory aseptically. Routine isolation and identification of S. aureus was conducted and the isolates were confirmed by polymerase chain reaction (PCR) through the detection of a S. aureus specific gene, nucA. Antimicrobial sensitivity tests were conducted according to Kirby-Bauer methods (Hudzicki, 2013). Staphylococcus aureus was isolated in 24% (12/50) of the samples. All the isolates were resistant towards at least two of the antimicrobials tested. Of these, 11 (91.67%), 10 (83.33%), 5 (41.67%), 3 (25%), 1 (8.33%) and 1 (8.33%) were resistant to ampicillin (AMP10), teicoplanin (TE30), amoxicillin (AML10), penicillin (P10), oxacillin (OX1) and mupirocin (MUP20) respectively. In addition to that, all the isolates were susceptible to streptomycin, vancomycin, teicoplanin and cefoxitin. However, all the isolates were negative for the methicillin resistance encoding gene, mecA while one of the isolates showed resistance towards oxacillin. Conclusion, significance and impact of the study: The results from this study indicated that raw chicken intended for human consumption may be contaminated by antimicrobial-resistant strains of S. aureus. This may lead to the colonization or infection in humans. Nevertheless, further detailed investigation to determine the correlation between contamination of chicken meat and colonization of antimicrobial resistant S. aureus should be carried out. The relevance of the present study which showed contamination of fresh chicken meat with antimicrobial resistant S. aureus emphasizes the need to have stricter hygiene measures for retailers during the handling of the chicken meat to minimize or avoid possible health hazards for consumers.
