Objective:To determine the total polyphenol content,antioxidant activity and antibacterial properties of the extracts of different Bangladeshi tea varieties such as flowery broken orange pekoe,broken orange pekoe,red dust and green tea.Methods:Total phenolic and flavonoid contents were determined by Folin-Ciocalteu and aluminum chloride colorimetric assay,respectively.The antioxidant capacity was determined by ferric ion reducing antioxidant power and phosphomolybdenum method.Antibacterial activity was evaluated by disc diffusion method in agar plate and subsequently,the minimum inhibitory concentration was determined by broth dilution method.Results:Total phenolic and flavonoid contents were significantly higher (P ＜ 0.05) in green tea compared to other three black tea varieties.The green tea also showed a higher free radical scavenging amd antioxidant activities than all the other tea varieties tested (P ＜ 0.05).In addition,the extracts of all four tea varieties showed inhibitory activity against several pathogenic bacteria and also the same trend of higher antimicrobial activity of green tea than other tea varieties was observed.Contusions:Taken together,the results of this study demonstrated that Bangladeshi tea,especially the green tea,may act as a substitute for natural antioxidants and as a promising antibacterial agent for bcncficial influence in human health.

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.

PURPOSE: No study had been conducted to assess the hospitals' environment for learning purposes in multicenter sites in Saudi Arabia. It aims to evaluate the environment of hospitals for learning purposes of pediatric residents. METHODS: We applied Postgraduate Hospital Educational Environment Measure (PHEEM) to measure the learning environment at six teaching hospitals in the Eastern Region of Saudi Arabia from September to December 2013. RESULTS: The number of respondents was 104 (86.7%) out of 120 residents and 37 females and 67 male residents have responded. The residents' response scored 100 out of 160 maximum score in rating of PHEEM that showed overall learning environment is favorable for training. There were some items in the social support domain suggesting improvements. There was no significant difference between male and female residents. There was a difference among the participant teaching hospitals (p<0.05). CONCLUSION: The result pointed an overall positive rating. Individual item scores suggested that their social life during residency could be uninspiring. They have the low satisfactory level and they feel racism, and sexual discrimination. Therefore, there is still a room for improvement.

COVID-19 has caused extensive human casualties with significant economic impacts around the globe, and has imposed new challenges on health systems worldwide. Over the past decade, SARS, Ebola, and Zika also led to significant concerns among the scientific community. Interestingly, the SARS and Zika epidemics ended before vaccine development; however, the scholarly community and the pharmaceutical companies responded very quickly at that time. Similarly, when the genetic sequence of SARSCoV-2 was revealed, global vaccine companies and scientists have stepped forward to develop a vaccine, triggering a race toward vaccine development that the whole world is relying on. Similarly, an effective and safe vaccine could play a pivotal role in eradicating COVID-19. However, few important questions regarding SARS-CoV-2 vaccine development are explored in this review.

Dengue Fever is a major public health issue in Malaysia. This study aimed to assess knowledge, attitude and practice regarding dengue fever and effectiveness of health education programme among 204 students of Alam Shah Science School, Cheras/Kuala Lumpur. Study design was a cross sectional study followed by an interventional (pre-post) Study. The self-administered questionnaire included questions on sociodemographic factors, knowledge, attitude and practice regarding dengue fever. Majority of respondents were Malays (96.6%), monthly family income more than RM 3000 (64.6%) and lives in urban area (64.6%). There was no significant association between knowledge status and socio-demographic factors (p-value>0.05). Most of the respondents had good knowledge (63.2%) good attitudes (79.9%) regarding dengue fever. However, practices to prevent dengue was poor (74.0%). Only about one-fifth of the respondents (18.2%) believed that dengue fever is a flu-like illness. Knowledge score was significantly increased after health education programme (p value <0.001). There is a need to increase health education activities through campaigns and mass media to increase knowledge regarding dengue fever. This would help to inculcate positive attitudes and cultivate better preventive practices among the public to eliminate dengue fever in the country.

Stress is accepted as the accumulation of unpleasant state of physical, mental and emotion on a person. Medical education has been known as one of the most stressful academic curriculum. Hence, medical students may subjected to multiple psychological changes and challenges throughout the years of medical education. The aim of this study was to determine the prevalence of stress and its associated factors among medical students. This cross sectional study was conducted from April to May 2018 in medical school in Sabah. It involved 396 medical students through universal sampling. Self-administered questionnaires were used as an instrument for data collection. The questionnaires included were Sociodemographic Questionnaire, Depression, Anxiety and Stress Scales 21 (DASS-21) and Medical Student Stressors Questionnaire (MSSQ). Bivariate analysis (Chi Square test, Fisher’s Exact Test, Independent T test and Man-Whitney U test) were used to analyse the association. The response rate was 90.2%. The prevalence of stress among medical students were 33.3%. Significant associated factors include financial support inadequacy (p=0.010) and all categories of medical student stressors. The mean score of the academic related stressors was found to be at 2.117 (±0.758) which was the highest mean score among medical student stressors assessed by MSSQ. The result of this study can be used as a basis for implementation of preventive measures such as provision of comprehensive, integrated and responsive mental health care services in university-based settings.

SUMMARY Introduction: Urinary tract infection (UTI) is a common bacterial infection affecting children and therefore, prompt recognition and accurate antimicrobial management are vital to prevent kidney damage. This study aims to determine the bacterial pathogens and their patterns of antimicrobial resistance in children presenting with UTI. Methods: A retrospective study of 721 cases, involving children between the ages of 1-day old to 13 years old with culture-proven UTI in Selayang Hospital, Malaysia between January 2007 and December 2011. The bacterial pathogens and antibiotic resistance patterns in the total population, prophylaxis and no prophylaxis groups were studied. Results: The 3 most common organisms isolated in the total population were E.Coli (41.6%), Klebsiella spp. (21.2%) and Enterococcus spp. (11.0%). With regards to the antibiotic resistance, E.Coli resistance rates to ampicillin, cefuroxime and gentamicin were 67.7%, 15.3% and 7.3% respectively. Ampicillin-resistance was also highest in Klebsiella spp. (84.3%), Enterococcus spp. (15.5%) and Proteus spp. (55.5%). Conclusion: E.coli remains to be the leading bacterial pathogen causing UTI in children, with ampicillin-resistance occurring in more than half of these cases. Therefore, accurate choice of antibiotics is important to ensure optimal outcome. In our study, cefuroxime and gentamicin have lower antibiotic resistance rates and can be used in the treatment of UTI in children.

Introduction Tuberculosis (TB) a major global health challenge especially in low- and middle-income countries reflects improper, delayed or missed diagnosis. Contact screening should be utilized both as an efficient and effective targeted approach to intensify TB case finding.Methods Through a comprehensive systematic literature review of online database, this paper aims at providing an insight into the current practice of TB contact screening and to provide evidence based practice for formulation of appropriate policies in low- and middle-income countries. There are 24 articles included in this review from studies published from 2005 to 2014.Results Findings in literature varies substantially. Generally, contact screening is better intensified with clear operational guidelines, adequate training, include close contact outside household as appropriate and follow up at least for 1 year. Prioritizing high risk close contacts is helpful in resource limited setting. Tuberculin skin test is still of value as screening tool and intensified case finding must be accompanied with effective management protocol. Prophylaxis treatment is recommended especially for children especially less than 5 years old, unvaccinated, malnourished, living with person having HIV and close contact with MDR-TB.Conclusion Policy recommendations in improving TB management must incorporate complementary strategies to enhance case finding, effective management protocol for follow up or prophylaxis treatment, training for public health capacity and concerted dedication from various stakeholders.

Background: Scheuermann’s disease is the most common cause of hyperkyphosis of the thoracic spine during the adolescence period. It causes neck and lower back pain, restriction of lung expansion, traction of the spinal cord, increased vulnerability to vertebral fracture, and a hump. Patients with curves < 60° are treated conservatively, while surgery is used for patients with curves > 60°. The purpose of this prospective cohort study was to assess the quality of life and functional changes in conservatively or surgically treated Scheuermann’s disease patients with a curve size of 50°–65° in north Jordan. Methods: Sixty-three adolescent patients with Scheuermann’s kyphosis (aged between 10 and 18 years) were treated at our hospital between January 2014 and August 2018. All patients were investigated clinically, radiologically (Cobb’s angle), and functionally (Oswestry Disability Index [ODI], Scoliosis Research Society 22 revision [SRS-22r] questionnaire, and pulmonary function test [PFT]) preand post-treatment (final follow-up). Patients were randomly selected for treatment method (conservative versus surgical). Results: There were 31 patients (mean age, 15.48 ± 2.50 years) and 32 patients (mean age, 16.19 ± 1.51 years) treated conservatively and surgically, respectively. Mean ± standard deviation of ODI, SRS-22r, and Cobb’s angle of the surgical group improved from 16.8% ± 14.3%, 3.5 ± 0.5, and 58.75° ± 3.59°, respectively, pre-surgery to 13.4% ± 10.8%, 4.2 ± 0.5, and 41.53° ± 3.94°, respectively, post-surgery, while those of the conservative group became worse from 12.6% ± 13.4%, 3.9 ± 0.7, and 56.1° ± 3.3°, respectively, to 20.1% ± 13.6%, 3.5 ± 0.7, and 58.8° ± 5.8°, respectively. The surgical group showed better improvement in all scores than the conservative group (p < 0.05), as well as in PFT. Conclusions Surgical treatment of Scheuermann’s kyphosis with curves of 50°–65° resulted in better QOL, Cobb’s angle, and PFT than conservative treatment. This was because of lower patient cooperation in the conservative management group, which made the curve less flexible for exercises and bracing.
