METHODS: A systematic review was conducted on breast cancer screening studies among Malaysian women, published between January 2006 and December 2015. Online databases were searched using keywords: "mammogram", "mammography", "uptake", "breast cancer screening" and "Malaysia".
RESULTS: Thirteen original articles were reviewed. The rate of mammography uptake ranged between 3.6% and 30.9% among the general population, and 80.3% among personnel of a tertiary hospital. Factors associated with mammogram screening were clinical breast examination, age, income, knowledge on breast cancer and mammogram, perceived susceptibility to breast cancer, ethnicity and education level. Barriers to mammogram screening were lack of knowledge, embarrassment, fear of cancer diagnosis, perception that breast screening was unnecessary, lack of coping skills and pain during procedure. However, almost all of the studies could not be generalised beyond the study sample because of the limited number of sites and respondents; and most data were self-reported with no objective measures of the responses.
CONCLUSION: Mammogram screening uptake among women in selected communities were generally low. Further studies involving the general population are essential. Future studies should also explore the availability, affordability and accessibility of this service especially in the pursuit of achieving universal health coverage in breast cancer management.
METHODOLOGY: Data were obtained from a cross-sectional survey in ten different nursing homes in the state of Penang, Malaysia. Participants were selected through convenience sampling were interviewed face-to-face using a questionnaire. Information concerning demographic characteristics, fall risk and depression status were collected.
RESULTS: Of the 357-elderly aged 60 years and above interviewed in the nursing homes, 32.8% (n=354) reported having one or more falls in the past 12 months whereas 13.3% were at moderate/high risk of fall. Depression (Adjusted Odds Ratio (aOR)=1.71, 95%CI: 1.00 to 2.91) and respiratory illnesses (aOR=3.38, 95%CI: 1.11 to 10.30) were shown to be associated with prevalence of falls. Depression (aOR=2.12, 95%CI: 1.06 to 4.23) and history of fall more than once in the past 12 months (aOR=3.90, 95%CI: 1.72 to 8.8) were found to be associated with moderate/high risk of falls.
CONCLUSION: This study showed that the prevalence of fall was higher among depressed elderly and those with respiratory illness. Elderly with higher history of falls were also at higher risk of falls. These findings suggest the importance of screening the elderly for the risk factors of falls as a preventive measure.
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.
METHODS: This was a cross-sectional survey using convenient sampling of 192 RA patients who attended the Rheumatology Clinic outpatient appointment, Hospital Melaka from June 2013 to December 2013. Depression, Anxiety and Stress Scale (DASS21) questionnaire was used to evaluate symptoms of depression, anxiety and stress. RA disease activity was assessed using the DAS28-ESR formula. Functional status was assessed via the Health Assessment Questionnaire Disability Index (HAQ-DI).
RESULTS: Out of 189 completed questionnaires, 46%(n=86) patients reported psychological distress symptoms, and 25%(n=48) experienced more than one negative emotional states. The prevalence of depression, anxiety and stress among our patients were 23.3%(n=44), 42.3%(n=80) and 20.1%(n=38) respectively. There were significant positive correlations (p<0.05) between these psychological symptoms with disease activity, number of tender joints, general health, pain and HAQ score. Age was inversely correlated with depression, anxiety and stress. Higher number of swollen joints correlated positively with depression but not with anxiety and stress. HAQ was the only independent predictor for depression (Odds Ratio [OR]=2.07; 95%CI: 1.19 to 3.61) and anxiety (OR=1.81; 95%CI: 1.1 to 3.0) whilst pain was found to be independent predictor for stress (OR=1.04; 95%CI: 1.0 to 1.1).
CONCLUSION: The incidence of depression and anxiety in our Malaysian sample of RA patient was comparable to that observed in Caucasian populations. Functional status was an independent predictor of depression and anxiety, whereas pain was an independent predictor of stress.
METHODS: A participant blinded, multi-centre, randomised controlled trial was conducted in which the participants in the intervention group (IG) practiced deep breathing exercise guided by sound cues and those in the control group (CG) listened to the music. The primary end point was reduction in blood pressure at eight weeks.
RESULTS: 87 patients, 46 males and 41 females with mean age of 61.1 years were recruited and 93.1% of them successfully completed the study. There was significant reduction in systolic and diastolic Blood Pressure from baseline by 8 weeks in both groups. The reduction in Mean systolic blood pressure (SBP) in the control arm was 10.5mmHg compared to 8.3mmHg (p<0.001) in intervention group. Diastolic blood pressure (DBP) reduction in control and intervention groups were 5.2 mmHg (p<0.001) and 5.6 mmHg (p<0.001) respectively. The absolute difference in SBP reduction from baseline in IG & CG was -2.2 (95%CI: -7.8 to 3.5) and DBP was -0.4 (95%CI: -2.9 to 3.6). However, blood pressure reduction between the two groups was not significant.
CONCLUSIONS: Both listening to music and deep breathing exercise were associated with a clinically significant reduction in SBP and DBP. However, deep breathing exercise did not augment the benefit of music in reducing BP.
METHODS: A cross-sectional study was conducted among pregnant women from four antenatal clinics in Seremban, between February and May 2015. Knowledge on pregnancy risks was assessed using questionnaire. Women were defined as having broad knowledge on obesity related pregnancy risks if they correctly identified that women who are very obese, are at higher risk of obesity related pregnancy complications and weight loss prior to pregnancy is associated with lower risk of obesity related pregnancy complications. Descriptive statistics and regression tests were used in the analysis.
RESULTS: A total of 315 women participated in this study. Their mean age is 29.3 (SD±4.8) years and majority were Malay (72.4%). More than half of them were overweight and obese (60.6%). About 63.2% participants had broad knowledge on obesity related pregnancy risk. Education is a significant predictor of broad knowledge as women with tertiary education had higher odds of having broad knowledge compared to those with only school education (OR 2.1; 95%CI: 1.28 to 3.59).
CONCLUSIONS: This study found that more than half of the participants had knowledge of obesity related pregnancy risks and that education is a significant predictor for knowledge. Pre-pregnancy care education programmes can help identify barriers, introduce simple weight management strategies to overcome obesity, to ensure better maternal and foetal outcome.
MATERIALS AND METHODS: A randomised, double-blinded, placebo-controlled trial was carried out in eight patients with chronic rhinosinusitis or nasal polyposis who were planned for bilateral endoscopic sinus surgery. A Peri-operative Sinus Endoscopy (POSE) Score and Lund-Kennedy Endoscopic Score (LKES) were recorded. The use of hydrocortisone-impregnated Gelfoam dressing versus normal saline-impregnated Gelfoam dressing were compared. Scores were repeated post-operatively at one week, three weeks and three months interval.
RESULTS: For LKES, at the end of three months, 50% of the patients had the same score difference, 37.5% had better results on the study side while 12.5% had better results on the control side. Meanwhile, for POSE Score, at the end of three months, 75% of the patients had better score difference on the study side while 12.5% had better results on the control side.
CONCLUSION: Gelfoam can be used as nasal packing material to deliver topical steroid after endoscopic sinus surgery. Steroid-impregnated nasal dressing after endoscopic sinus surgery may not provide better long-term outcome.
METHODS: These models utilized experimental data of wavelengths and hemoglobin concentrations in building highly accurate Genetic Algorithm/Support Vector Regression model (GA-SVR).
RESULTS: The developed methodology showed high accuracy as indicated by the low root mean square error values of 4.65 × 10-4 and 4.62 × 10-4 for oxygenated and deoxygenated hemoglobin, respectively. In addition, the models exhibited 99.85 and 99.84% correlation coefficients (r) for the oxygenated and deoxygenated hemoglobin, thus, validating the strong agreement between the predicted and the experimental results CONCLUSIONS: Due to the accuracy and relative simplicity of the proposed models, we envisage that these models would serve as important references for future studies on optical properties of blood.
METHOD: In this study, we implement FWF as an energy minimization function to replace the standard gradient-descent method as minimization function in Chan-Vese segmentation technique. The proposed FWF is used to find the boundaries of an object by controlling the inside and outside values of the contour. In this study, the objective evaluation is used to distinguish the differences between the processed segmented images and ground truth using a set of statistical parameters; true positive, true negative, false positive, and false negative.
RESULTS: The FWF as a minimization of energy was successfully implemented on BRATS 2013 image dataset. The achieved overall average sensitivity score of the brain tumors segmentation was 94.8 ± 4.7%.
CONCLUSIONS: The results demonstrate that the proposed FWF method minimized the energy function more than the gradient-decent method that was used in the original three-dimensional active contour without edge (3DACWE) method.
OBJECTIVES: The present study was aimed to investigate the effect of E. longifolia on the proliferation, differentiation and maturation of osteoclasts and the translational mechanism of inhibition of osteoclastogenesis using RAW 264.7 cells as an in vitro osteoclastic model.
MATERIALS AND METHODS: Having assessed cytotoxicity, the cell viability, cell proliferation rate and osteoclastic differentiation capacity of E. longifolia was investigated by evaluating the tartrate-resistant acid phosphatase (TRAP) activity in receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL)-induced osteoclasts. Taken together, the time-mannered expression of osteoclast-related protein biomarkers such as matrix metallopeptidase-9 (MMP-9), cathepsin-K, TRAP, nuclear factor of activated T-cells cytoplasmic 1 (NFATc1), superoxide (free radicals) generation and superoxide dismutase activity were also measured to comprehend the mechanism of osteoclastogenesis.
RESULTS: E. longifolia did not show significant effects on cytotoxicity and cell proliferation of RAW 264.7 cells; however, a significant inhibition of cells differentiation and maturation of osteoclasts was observed. Moreover, a significant down-regulation of RANKL-induced TRAP activity and expression of MMP-9, cathepsin-K, TRAP, NFATc1 and generation of superoxide and enhanced superoxide dismutase activity was observed in E. longifolia treated cell cultures.
CONCLUSION: We anticipated that E. longifolia that enhances bone regeneration on the one hand and suppresses osteoclast's maturation on the other hand may have great therapeutic value in treating osteoporosis and other bone-erosive diseases such as rheumatoid arthritis and metastasis associated with bone loss.
METHODS: In this quasi-experimental, posttest-only nonequivalent control group design, the subjects were undergraduate students who had enrolled in Pediatric Nursing II at Islamic Azad University in Iran. The experiment was conducted over a period of eight weeks, one two-hour session and two two-hour sessions. Two experimental groups, Pure Problem-Based Learning (PPBL) and the Hybrid Problem- Based Learning (HPBL), and one Lecturing or Conventional Teaching and Learning (COTL) group were involved. In the PPBL group, PBL method with guided questions and a tutor, and in the HPBL group, problem-based learning method, some guided questions, minimal lecturing and a tutor were used. The COTL group, however, underwent learning using conventional instruction utilizing full lecture. The three groups were compared on cognitive performances, namely, test performance, mental effort, and instructional efficiency. Two instruments, i.e., Pediatric Nursing Performance Test (PNPT) and Paas Mental Effort Rating Scale (PMER) were used. In addition, the two-Dimensional Instructional Efficiency Index (IEI) formula was utilized. The statistical analyses used were ANOVA, ANCOVA, and mixed between-within subjects ANOVA.
RESULTS: Results showed that the PPBL and HPBL instructional methods, in comparison with COTL, enhanced the students' overall and higher-order performances in Pediatric Nursing, and induced higher level of instructional efficiency with less mental effort (p
