Chitinases (designated as SPCs) were isolated from „Shilbilati‟ potatoes, a potato prototype cultivated in Bangladesh by affinity chromatography on a chitin column. SPCs agglutinated rat erythrocytes at the minimum concentration of 7 μg/mL and showed toxicity against brine shrimp nauplii with the LC50 value of 20 μg/mL. The chitinases also agglutinated seven bacterial strains among the twelve as studied. Pseudomonas aeruginosa, Bacillus subtilis and Salmonella typhi were the most sensitive towards the SPCs and were agglutinated at 1.2, 2.5 and 5.0 μg/mL protein concentrations respectively. Antibacterial tests demonstrated that SPCs showed inhibitory activity against the pathogenic bacteria Staphylococcus aureus, Bacillus subtilis and Salmonella typhi. Antifungal activity was investigated by the disc diffusion method. Five fungal species (Candida albicans, Aspergillus niger, Fusarium vasinfectum, Aspergillus fumigatus and Aspergillus flavus) and two fungal genus (Penicillium and Mucor sp.) were examined in the assay. SPCs showed antifungal activity against Candida albicans, Fusarium vasinfectum and Penicillium sp.

Objective: The MINI International Neuropsychiatric Interview (MINI) is a short, structured diagnostic interview compatible with the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). It was designed for clinical practice, research in psychiatric, primary care settings and epidemiological surveys. This preliminary study aims to evaluate the reliability and validity of the Malaysian Version of MINI for Major Depressive Disorder and Generalized Anxiety Disorder symptoms criteria only. Methods: Six hours of MINI training was given as part of a National Health Morbidity Survey training program for layman interviewers (n=229) and three videos were prepared by an expert psychiatrist for inter-rater reliability purposes. Meanwhile, for validity purposes, the MINI was administered to patients with Major Depressive Disorder (n=30), Generalized Anxiety Disorder (n=20) and to a normal population (n=60), to conform against the Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) that was administered by psychiatrists. Results: Overall the inter-rater reliability was satisfactory (0.67 to 0.85) and the concordance between the MINI’s and expert diagnoses was good, with kappa values of greater than 0.88. Conclusions: The Malay version of the MINI is adjusted to the clinical setting and for the assessment of positive cases in a community setting. Modifications were highlighted to correct any identified problems and to improve the reliability of the MINI for future research and clinical use.

Being a rare clinical entity, discal cyst presents indistinguishably from other causes of lower back pain and radiculopathy. It is an extremely rare pathology with unclear pathogenesis, indeterminate natural history with no consensus on the ideal management of the condition. We report a rare case of discal cyst in a patient who presented to our centre with localised low back pain and subsequently left sided radicular pain. With the aid of MRI and with clear surgical indication we proceeded with endoscopic removal of the cyst and intraoperatively confirmed its origin from the adjacent disc. The patient had immediate relief of his symptoms and no postoperative complications. We recommend that endoscopic surgery can be an effective alternative to conventional open surgery for discal cyst of the lumbar spine.

practice and care environments are important aspects ofnursing care. The use of a reliable and valid scale canmonitor the quality of handover and provide information forcontinuous improvement of practice. This study aims todescribe the perception of nurses, on the domains of qualityof information, efficiency, interaction and support andpatient involvement. Method: A cross-sectional descriptive study was conductedamong 450 nurses from 37 wards in Hospital Kuala Lumpur.Nurses on shift duty were recruited by conveniencesampling from the Medical, Surgery, Obstetrics &Gynaecology, Orthopaedic and Paediatric wards. Using avalidated questionnaire (Handover Evaluation Scale), nursesself-rated their perceptions using a 7-point scale andprovided open-ended responses to the strengths andchallenges that they faced. Descriptive and inferentialanalyses were done while open-ended questions weresummarised based on key themes. Results: A total of 414 nurses completed the survey (92.0%response rate). Nurses had an overall mean (SD) perceptionscore of 5.01 (SD 0.56). They perceived good interaction andsupport during handover and on the quality of informationthat they received, with mean scores of 5.54 (SD 0.79) and5.19 (SD 0.69), respectively. There was an associationbetween the departments where the nurses worked and theiroverall perceptions on nursing handover (p<0.001).Interruptions being the most common theme emerged fromthe open-ended section.Conclusion: Despite having substantial interaction andsupport amongst nurses, opportunities for improvementswere noted. Improvements in the quality of handoverinformation and reducing interruptions should be the mainemphases as these were perceived to be essential in thecurrent handover practices by nurses.

Introduction: Many countries struggle to supply enough blood while maintaining their quality and safety. Increasing the number of regular donors is expected to increase the donor pool and blood safety. Thus, this study describes lapsed and regular blood donors’ characteristics, knowledge, motivation, and barriers concerning blood donation. Methods: This observational cross-sectional study has adopted an assisted self-administered questionnaire, which was distributed to blood donors at the Department of Transfusion Medicine, Hospital Sultanah Bahiyah, Kedah. A total of 328 participants consisting of 164 lapsed and 164 regular donors were selected. Logistic regression tests were used to determine the factors that predict lapsed donors. Results: Out of the selected 328 respondents, 54.3% were in the 25–39 age group, 66.2% were males, and 85.1% were Malays. Most of the respondents (88.4%) showed adequate blood donation knowledge, and 99.7% cited altruism as a motivator for blood donation. About 47.0% of the respondents claimed they lack enough time as their donation barrier. Donors who were younger in age, had a moderate blood donation knowledge (adjusted OR, 3.60; 95% CI, 1.34-9.64), didn’t know where to donate (adjusted OR, 2.79; 95% CI, 1.47-5.29), lack enough time (adjusted OR, 1.83; 95% CI, 1.04-3.24), and insufficient information about blood donation campaigns (adjusted OR, 2.19; 95% CI, 1.23-3.91) were more likely to lapse. Conclusion: Donor education, convenient time and location, and sufficient information about blood donation campaigns targeted at young donors are critical for preventing lapsed donors, which could subsequently increase the regular donor pool.

Aims: Aquaculture has grown tremendously in Malaysia over the past decades. However, guaranteeing aquaculture sustainability is a big challenge in terms of maintaining continuous output with a safe environment. Furthermore, the cultured species should be free from antibiotic resistance bacterial and antibiotic residue. This study aimed to monitor the existence and prevalence of antibiotic resistant bacteria associated with aquaculture farms in Sarawak. Methodology and results: Samples of water, sediment and fish were collected from five aquaculture farms within Sarawak. The samples were plated on trypticase soy agar and incubated at 28 °C for 24 h. A total of 204 bacterial isolates were isolated and analysed by (GTG)5-fingerprinting to determine genetic similarity among the bacterial isolates, so that representatives could be selected from similar clonal isolates. Based on the (GTG)5 profiles, 50 representative isolates were chosen for species identification using 16S rRNA sequencing. The identified bacteria were tested against 25 antibiotics using standard disk diffusion method. The 16S rRNA analysis revealed that the isolates constitute of 14 genera of bacteria including Bacillus (38%), Exiguobacterium (16%), Enterobacter (14%), Aeromonas (6%), Acinetobacter (4%), Citrobacter (4%), Staphylococcus (4%), Achromobacter (2%), Chitinophaga (2%), Fictibacillus (2%), Plesiomonas (2%), Pseudomonas (2%), Pseudoxanthomonas (2%) and Stenotrophomonas (2%). The antibiotic resistance analysis revealed that the highest percentage of resistance was recorded against streptomycin (75.0%), followed by ampicillin (66.0%), ceftriaxone (50.0%), rifampin (43.3%), aztreonam (36.8%) and ceftazidime (31.6%). Resistance to more than two antibiotics was observed in 40.0% of isolates with an overall multiple antibiotic resistant (MAR) index ranging from 0 to 0.79. Conclusion, significant and impact of study The variability of antibiotic resistance patterns exhibited by different bacterial species suggests a dependence on selective pressures exhibited in different geographical locations. Our results show that the occurrence of MAR bacteria in an aquaculture environment with unknown history of antibiotics usage in the aquaculture system is possible, indicating a need to continuously monitor the presence of antibiotic resistant bacteria in the aquaculture system.
