Background. This study determines the effects of a behavioral program on exercise adherence (step counts) and level of exercise self-efficacy (ESE) in community-dwelling older persons. Methods. Sixty-three participants (age = 63.8 ± 4.5 years) were enrolled in this controlled quasi-experimental study. They were divided into 3 groups: (1) EBG performed a 6-week exercise intervention followed by a 5-week behavioral program, (2) EG performed exercise intervention similar to EBG, and (3) control group (CG) did not receive any interventions. Step counts were measured based on the scores recorded by a pedometer while ESE was measured by a self-reported ESE scale. Results. Data analysis showed significant differences due to time effect (F(1,2) = 39.884, P < 0.01, and η = .399); time and group interactions (F(2,60) = 112.683, P < 0.01, and η = .790); and between-group effect (F(2,60) = 12.524, P < 0.01, and η = .295) for step counts. As for ESE, significant differences were also found for time effect (F(2,4) = 66.628, P < 0.05, and η = .526); time and group interactions (F(2,60) = 4.562, P = 0.014, and η = .132); and between-group effect (F(2,60) = 13.632, P < 0.05, and η = .312). EBG presented with significantly higher mean changes for both step counts and ESE compared to other groups (all P < 0.05). Conclusion. This study suggests that the addition of a behavioral program is superior as compared to exercising alone on increasing exercise adherence and level of self-efficacy in older persons.
This article describes the completed suicide patterns which occurred in the Timur Laut district of Penang Island, Malaysia. In a prospective cohort study over the three years period (2007-2009) there were 138 cases of suicide deaths. The number of suicide deaths for the year 2007, 2008 and 2009 were 45, 41 and 52 deaths, respectively. Majority of the suicide deaths were by jumping from height (47.1%), followed by hanging (34.1%) and by drowning (10.9%). The male victims outnumbered females in a 3 : 1 ratio.
The occurrence of post-operative wound infection was studied respectively over an eight month period in the University Hospital, Kuala Lumpur. One hundred and seventy four (3.4%) surgical wounds out of 5129 operations became infected. The clean wound infection rate was 2.9%, rising to 5.4% and 12.2% for clean-contaminated and contaminated surgical wounds respectively. Of the wound infections, 80.8% occurred within the first two weeks post-operatively. Bacteriological studies revealed that the commonest bacterial isolates were Staphylococcus aureus (36.1%), Pseudomonas aeruginosa (15.4%) and Klebsiella species (10.1%).
OBJECTIVE: Various techniques and instruments have been developed to provide safe and secure closure of laparoscopic wounds. Herein we describe a simple method to close laparoscopic supraumbilical wounds with the aid of a laparoscopic port.
METHOD: This was a retrospective review of prospective data, which were from 151 patients who underwent laparoscopic cholecystectomy for symptomatic gallstone disease from December 2009 to December 2010 in Sultanah Bahiyah Hospital. A senior consultant hepato-pancreato-biliary (HPB) surgeon and two HPB trainee surgeons performed the operations. Postoperatively, all patients were followed up at 4 weeks.
RESULTS: All patients successfully underwent closure of the supraumbilical wound with the assistance of a 5mm laparoscopic port. None of the patients had incisional hernia on follow up.
CONCLUSION: Port assisted closure of supraumbilical laparoscopic wounds is a feasible and safe technique.

INTRODUCTION: T-piece resuscitator (TPR) has many advantages compared to self-inflating bag (SIB). Early Continuous Positive Airway Pressure (CPAP) during newborn resuscitation (NR) with TPR at delivery can reduce intubation rate.
METHODS: We speculated that the intubation rate at delivery room was high because SIB had always been used during NR and this can be improved with TPR. Intubation rate of newborn <24 hours of life was deemed high if >50%. An audit was carried out in June 2010 to verify this problem using a check sheet.
RESULTS: 25 neonates without major congenital anomalies who required NR with SIB at delivery were included. Intubation rate of babies <24 hours of life when SIB was used was 68%. Post-intervention audit (August to November 2010) on 25 newborns showed that the intubation rate within 24 hours dropped to 8% when TPR was used. Proportion of intubated babies reduced from 48.3% (2008-2009) to 35.1% (2011-2012), odds ratio 0.58 (95% CI 0.49-0.68). Proportion of neonates on CPAP increased from 63.5% (2008-2009) to 81.0% (2011-2012), odds ratio 2.44 (95% CI 2.03-2.93). Mean ventilation days fell to below 4 days after 2010. Since then, all delivery standbys were accompanied by TPR and it was used for all NR regardless of settings. There was decline in intubation rate secondary to early provision of CPAP with TPR during NR. Mean ventilation days, mortality and length of NICU stay were reduced.
CONCLUSION: This practice should be adopted by all hospitals in the country to achieve Millennium Development Goal 4 (2/3 decline of under 5 mortality rate) by 2015.

BACKGROUND:
Research is an essential activity required for the advancement of science and improvement of human existence. To carry out a research, a proposal is mandatory. However, in spite of the widespread demand for research proposals, experience has shown that a number of them are so poorly written that they rejected by assessors. This article aims at assisting researchers develop acceptable research proposals by reviewing the different components of a research proposal.
METHOD:
A review of relevant literature on research proposal writing sourced from manual library and internet search was used for this review
RESULT:
A research proposal is a formal and detailed statement of intent to carry out a research. It presents and justifies a plan of action and shows how the investigator thinks. A research protocol on the other hand is a plan written to seek approval for research from a supervisor or an organization. It is developed as a guide for a study and helps to keep the researcher focused on the topic and scope of the research. A research proposal has the following components: The Title page; The Abstract/Executive Summary; The Introduction/Statement of the Problem; Literature Review; Information on the applicant's centre; The Objectives/Research Questions/Hypotheses; The Study Design; Methods; Plans for Analysis; Data Analysis; Plans for Data Interpretation; Plans to report. Thus, although proposals and protocols are sometimes used interchangeably, a proposal precedes a protocol.
CONCLUSION:
To reduce the time wastage and frustration faced by intending researchers and their assessors it is essential that good proposals be written at all times.
OBJECTIVES: The purpose of this study was to evaluate a multidisciplinary, interventional, ergonomic education program designed to reduce the risk of musculoskeletal problems by reducing schoolbag weight and correcting poor sitting posture.
METHODS: Data were collected twice before and twice following intervention using the Standardized Nordic Body Map Questionnaire, a rapid upper limb assessment for posture evaluation, and schoolbag weight measurement in children aged 8 and 11 years attending two schools within the central region of Malaysia.
RESULTS: Students who received the ergonomic intervention reported significant improvements in their sitting posture in a classroom environment and reduction of schoolbag weight as compared with the controls.
CONCLUSION: A single-session, early intervention, group ergonomics education program for children aged 8 and 11 years is appropriate and effective, and should be considered as a strategy to reduce musculoskeletal pain among schoolchildren in this age group.

This was a prospective randomised study comparing carboxyhaemoglobin concentrations between low-flow anaesthesia (fresh gas flow 1.0 L/min) and minimal-flow anaesthesia (0.5 L/min) using desflurane. Sixty (ASA 1 or 2) adult patients undergoing elective surgery under general anaesthesia were randomly allocated to receive either low-flow (Group 1) or minimal flow anaesthesia (Group 2). Venous blood samples for carboxyhaemoglobin levels were taken at baseline and at 10 mins intervals for 40 mins. Both groups showed significant increase in carboxyhaemoglobin concentrations within the first 10 mins when fresh gas flow of 4.0 L/min was used. Reduction in carboxyhemoglobin levels was seen after 20 mins of minimal or low flow anaesthesia. However, there was no significant difference in the magnitude of reduction of carboxyhemoglobin concentrations between the groups. The fractional inspired of oxygen (FiO2) showed no significant changes in either group. In conclusion, desflurane usage in anaesthesia with either low-flow or minimal-flow was not associated with increased carboxyhaemoglobin concentrations.
A prospective study of 92 children with poisoning admitted to University Hospital, Kuala Lumpur is reported. Majority of the affected children were below 3 years of age and belonged to low income families. Household items, especially kerosene, and medications were most often implicated. All children recovered completely. Preventive strategies are discussed.
Objective: In PBL, interaction in tutorial group plays a role in stimulating student learning. However, quality of group interactions need not be always in a desired level which will later affect group success. Hence the aim of this study was to ascertain the quality of group interactions during PBL sessions. Method: In this prospective, observational study, to obtain the perceptions of students and faculty (n = 32), a preformed questionnaire was used. Students from Ist (n = 129) and 2nd year (n = 106) of Bachelors of Medicine and Bachelors of Surgery (MBBS) program and faculty were asked to respond in the questionnaire during a PBL brain-storming session. To explore reasons for adequate and inadequate interactions, focus group (n = 10) discussions were conducted. Results: There was no difference in perceptions regarding interactions between 1st year and 2nd year students. But there was significant difference between students and faculty perceptions regarding posing critical questions (p = 0.002), counter argument (p = 0.001) and handling conflicts. Factors that drove interactions were the prior knowledge, assessment and motivation and the hindering factor was case scenarios which were not designed based on students’ prior knowledge. Conclusion: Faculty expectations regarding PBL group interaction is different from the students’ understanding of PBL interaction. This study helps us to bridge the gap between the faculty expectations and students’ performance by orienting them regarding an ideal PBL interaction.
Introduction: The LA-i was found to be valid, reliable, simple and easy to be administered and consumed minimal time. However, to author knowledge, none of articles reported its stability across multiple observations. Realising its potential, continued research is required to optimize its role, usefulness and applicability as a tool to help educators to understand their students’ learning approaches. Objective: To determine stability of the LA-i to measure characteristics of students’ learning approaches at different time and occasions in a sample of medical students.Method: A prospective cohort study was done on 177 first year medical students. It was administered to a cohort of medical students at four different intervals. The Cronbach’s alpha and intra-class correlation analysis were applied to measure internal consistency and agreement level across the
intervals. The analysis was done using SPSS 18. Result: A total of 157 (88.7%) first year medical students responded completely to the inventory. The overall Cronbach’s alpha value of the LA-i at different intervals ranged between 0.79 and 0.92, The Cronbach’s alpha values for surface learning
approach subscale ranged between 0.65 and 0.80. The Cronbach’s alpha value for strategic learning approach subscale ranged between 0.76 and 0.84. The Cronbach’s alpha value for deep learning approach subscale ranged between 0.83 and 0.95. ICC values for the three learning approach subscales ranged between 0.46 and 0.50. Conclusion: This study reflected that the LA-i had high level of internal stability to measure students’ learning approaches at different time and occasions. Continued research is required to optimize its role, usefulness and applicability at various educational settings.
This prospective randomised study was undertaken to compare surgical parameters as well as clinical and radiological outcomes of subvastus (SV) to midvastus (MV) approaches in staged bilateral total knee arthroplasty (TKA). Twenty-three patients, aged 55–76 years, who underwent staged bilateral TKAs, were followed up for 6 months. The SV approach was used on one knee and MV approach on the other. We found similar lateral retinacular release rates and patellar resurfacing rates between the two approaches .The SV approached knees had a more significant blood loss and increased operative time compared to the MV approached knees but they achieved significantly earlier active straightleg raises (SLR) postoperatively (p
A prospective study done In al Zaafaranya General Hospital in Baghdad/Iraq In the period between April 2003 and February 2007. Ninety two patients admitted to the surgical wards diagnosed as Intestinal obstruction. The aim is to find out the possible common conditions resulting in causing this common surgical emergency. Also to compare the provisional clinical diagnosis about ischemic obstruction and the definitive post operative diagnosis. To encourage post graduate students to use their clinical abilities with the few laboratory and radiological facilities available needed to decide about the management of those patients.
The evolution of instrumentation methods for C1-C2 fusion from the use of posterior wiring methods to transarticular screws and C1 lateral mass with C2 pedicle screw construct have improved fusion rates to almost 100%. However, the C1 lateral mass and C2 pedicle screw technique is technically demanding. This is a prospective review of a series of ten patients who was planned for C1-C2 fusion using C1 lateral mass and C2 pedicle screw technique between January 2007 and June 2009. The procedure was converted to occipital cervical fusion due to a fracture of a hypoplastic lateral mass-posterior arch complex in one patient and Gallie fusion due to a vertebral artery injury in another. Eight patients underwent the C1-C2 fusion using C1 lateral mass and C2 pedicle screw successfully without any complications. The union rate was 100% with an average union time of 5.3 months (range from 3 to 8 months). Postoperatively, the patients achieved an average of one Frankel grade neurological improvement. In conclusion, this technique provides an excellent union rate and good neurological recovery.
Objective: To determine association between academic performance and absenteeism in classroom among first year medical students.
Methods: A one-year prospective study was conducted on 196 first year medical students. Academic performance was measured by examination scores at four examinations. Absenteeism score was measured by the cumulative number of absence in an academic session of each student recorded by academic office at the end of the first year of medical training. The academic performance was categorized into pass and fail for analysis purpose. Data was analyzed by SPSS version 20.
Results: The independent-t analysis showed that, in all examinations, students who passed the examinations had significantly lower absenteeism scores than those who failed (p < 0.001).
Conclusion: This study found significant associations between academic performances and absenteeism scores among first year medical students. Medical schools should pay more attention on this matter since it may result in poor academic performances.
The present study investigates the prospective of substituting inorganic medium with organic food waste compost medium as a nutrient supplement for the cultivation of Chlorella vulgaris FSP-E. Various percentages of compost mixtures were replaced in the inorganic medium to compare the algal growth and biochemical composition. The use of 25% compost mixture combination was found to yield higher biomass concentration (11.1%) and better lipid (10.1%) and protein (2.0%) content compared with microalgae cultivation in fully inorganic medium. These results exhibited the potential of combining the inorganic medium with organic food waste compost medium as an effective way to reduce the cultivation cost of microalgae and to increase the biochemical content in the cultivated microalgae.
AIM: This prospective, single-group, pre-post design trial was conducted to evaluate the effect of individualised Medical Nutrition Therapy intervention administered by a dietitian in individuals with type 2 diabetes mellitus on glycaemic control, metabolic parameters and dietary intake.
METHODS: Subjects (n=104; age=56.4 ±9.9 years; 37% male; years of diagnosis = 6.3 ±4.9 years) treated with diet and on a stabile dose of oral anti-diabetic agents were given dietary advice by a dietitian for a 12 week period. Individualised dietary advice was based on Malaysian Medical Nutrition Therapy for adults with type 2 diabetes mellitus. The primary outcome measure was glycaemic control (fructosamine and HbA1c level) and the secondary outcome included measures of anthropometry, blood pressure, lipid profile, insulin levels dietary intake and knowledge on nutrition.
RESULTS: At week 12, 100 subjects completed the study with a dropout rate of 3.8%. The post-Medical Nutrition Therapy results showed a significant reduction of fructosamine (311.5 ±50 to 297 ±44 umol/L; P< 0.001) and HbA1c (7.6 ±1.2 to 7.2 +1.1%, p<0.001) with pronounced reduction for subjects who had very high HbA1c levels of >9.3% at baseline. Waist circumference (90.7 ±10.2 to 89.1 ±9.8 cm, p<0.05), HDL-cholesterol (1.1 ±0.3 to 1.2 ±0.3 mmol/L, p<0.05), dietary intake and nutrition knowledge score (42 ±19 vs. 75 ±17%; p< 0.001) were significantly improved from the baseline.
CONCLUSIONS: Individualised Medical Nutrition Therapy administered by a dietitian resulted in favourable diabetes outcomes, which were more apparent for individuals with higher than optimal HbA1c levels at the start of the study.
Inflammatory bowel diseases (IBDs) are immune mediated diseases affecting the gastrointestinal tract. Several environmental factors in concert with genetic susceptibilities can trigger IBDs. Recently, one of the important environmental factors contributing to the development of autoimmune diseases is vitamin D (VitD) deficiency. Furthermore, some new evidence points to VitD deficiency and its receptor dysfunction as an underlying factor for the emergence experimental IBDs. The aim of the current study was to evaluate the correlation between serum 25(OH)D concentrations and IBD activity in patients with ulcerative colitis or Crohn's disease. Sixty patients with confirmed diagnosis of IBD were recruited for a cross sectional study. Most of the identified confounders affecting serum VitD concentrations were excluded. Disease activity was assessed using validated questionnaires, including Truelove for Ulcerative Colitis and Crohn Disease Activity Index (CDAI) for Crohn disease. Serum 25(OH)D concentrations were determined by chemiluminescent assay. Serum 25(OH)D≤10 (ng/ml) was considered as VitD deficiency and 11≤25(OH)D<29(ng/ml) as VitD insufficiency. Mean serum 25(OH)D value was 13.1 ± 11.1(ng/ml) in IBD patients. Almost 95% of patients were vitamin D insufficient or deficient. Forty one percent of IBD patients had active disease. VitD deficiency was not associated with IBD activity (p=0.23). However, VitD deficiency was significantly associated with a history of IBD related intestinal surgery (p=0.001). In conclusion, this cross-sectional prospective study suggested that there is no association between vitamin D deficiency and disease activity in a relatively small number of IBD patients in a short period of time.
Medications given via the intravenous (IV) route provide rapid drug delivery to the body. IV therapy is a complex process requiring proper drug preparation before administration to the patients. Therefore, errors occurring at any stage can cause harmful clinical outcomes to the patients, which may lead to morbidity and mortality. This was a prospective observational study with the objectives to determine whether medication errors occur in IV drug preparation and administration in Selayang Hospital, determining the associated factors and identifying the strategies in reducing these medication errors. 341 (97.7%) errors were identified during observation of total 349 IV drug preparations and administrations. The most common errors include the vial tap not swabbed during prepreparation and injecting bolus doses faster than the recommended administration rate. There was one incident of wrong drug attempted. Errors were significantly more likely to occur during administration time at 8.00am and when bolus drugs were given. Errors could be reduced by having proper guidelines on IV procedures, more common use of IV infusion control devices and by giving full concentration during the process. Awareness among the staff nurses and training needs should be addressed to reduce the rate of medication errors. Standard IV procedures should be abided and this needs the cooperation and active roles from all healthcare professionals as well as the staff nurses.
