    INTRODUCTION: Disaster can occur at any time any place. Disaster preparedness plays an important role to reduce the loss of a community/country. The aim of this interventional study was to ascertain the impact of a video-based educational intervention program on improvement in knowledge and attitude of paramedical students in a hospital.

    MATERIALS AND METHODS: A pre-post study (interventional study design) was conducted on paramedic students. Our study period was 6 months which was divided into Phases I, II, and III. For administrative purpose, we included all paramedical students, and our sample size was 119. The baseline assessment of knowledge and attitude of paramedic students was done by a pretested questionnaire (Observation 1) with having a baseline scoring. After that, intervention Phase 1 was implemented, and later, end line observation (Observation 2) was made. Changes in knowledge and attitude were observed by the score difference (Observation 2-Observation 1). Descriptive statistics were calculated, and the mean of cumulative score was compared using the Wilcoxon signed-rank test. We applied Mann-Whitney U-test for finding associations between dependent variables with an independent variable using SPSS version 22 (IBM, Chicago, USA) software.

    RESULTS: Our baseline results showed that most of our participants had average knowledge (54.6%), followed by poor knowledge (24.4%). Approximately one-fifth (21.0%) of the participants had good knowledge regarding disaster preparedness. A significant improvement was observed in cumulative score (P < 0.005). A significant difference was observed in knowledge and attitude with respect to age and courses (P < 0.05). Forty percent of the students responded that they would like to get trained by that mock drill, and 26.1% were interested in disaster preparedness workshops in the future.

    CONCLUSION: Our present study results indicate that the overall knowledge and attitude level of the students was average and required improvement. A similar result was reported in some studies conducted globally for the same purpose. All of our students perceived that training for disaster preparedness is necessary for all health facilities, and it is important to have an emergency plan and disaster management committee. Regarding training methods, most of our students liked our interactive audiovisual method. However, their preferred methods were mock drill and workshops. It can be arranged in the future for them.

    The high species richness of tropical forests has long been recognized, yet there remains substantial uncertainty regarding the actual number of tropical tree species. Using a pantropical tree inventory database from closed canopy forests, consisting of 657,630 trees belonging to 11,371 species, we use a fitted value of Fisher's alpha and an approximate pantropical stem total to estimate the minimum number of tropical forest tree species to fall between ∼ 40,000 and ∼ 53,000, i.e., at the high end of previous estimates. Contrary to common assumption, the Indo-Pacific region was found to be as species-rich as the Neotropics, with both regions having a minimum of ∼ 19,000-25,000 tree species. Continental Africa is relatively depauperate with a minimum of ∼ 4,500-6,000 tree species. Very few species are shared among the African, American, and the Indo-Pacific regions. We provide a methodological framework for estimating species richness in trees that may help refine species richness estimates of tree-dependent taxa.

    Background: The objective of the current study was to adapt the Index of Dental Anxiety and Fear (IDAF-4C) in the Urdu language and measure its validity and reliability.

    Methods: Original English questionnaire of IDAF-4C was translated into Urdu language by a panel of dentists and language experts (Urdu and English) followed by critical evaluation, modification and back translation into English language. A final Urdu questionnaire was distributed among 250 patients visiting the Endodontics section at Margalla Institute of Health Sciences (MIHS), Rawalpindi, Pakistan. Cronbach's alpha was used to determine the reliability of the Index whereas validity was assessed by exploratory factor analysis (EFA). Mean rank scores of IDAF-4C for male and female participants were evaluated using Mann-Whitney U tests (P < 0.05).

    Results: Of 250 questionnaires, 209 were returned with a response rate of 84%. Cronbach's alpha for the Urdu version of IDAF-4C was 0.88. Exploratory factor analysis of the IDAF-4C revealed one factor explaining 55.55% of the common variance (Eigenvalue = 4.5). The mean rank scores of all eight items of IDAF-4C were greater for female participants as compared to male participants with a statistically significant association (P < 0.05).

    Conclusion: The psychometric analysis of the Urdu version of IDAF-4C showed good reliability and consistency compared to the original version as well as other translated versions.

    Background: The administration of systemic corticosteroids in chronic obstructive pulmonary disease (COPD) exacerbation is the first line of management. The duration of this administration, however, is not well established in clinical practice. The objective of this study is to compare the clinical outcomes between short-term and long-term corticosteroid use in the acute exacerbation of COPD patients.

    Methods: A single-centre, retrospective cohort study was conducted. From 2014 to 2018, all patients over 40 years old with COPD who were admitted to the hospital with a case of COPD exacerbation and received systemic corticosteroids at presentation were included. The subjects were divided into two groups according to the duration of systemic corticosteroid therapy. The primary outcome was hospital re-admission within 180 days. The secondary outcomes were 30 days mortality and length of hospitalisation. The two groups were compared using an independent sample t-test, a Chi-square test, and a Mann-Whitney U test, according to the data type.

    Results: Eighty patients met the inclusion criteria. A total of 52 (65%) patients completed long-term therapy, while 28 (35%) patients were on short-term treatment. A total of 15 (28.8%) patients reached the primary endpoint in the long-term treatment group versus 19 (67.9%) in the short-term treatment group (P = 0.001). The 30-day mortality was 4 (7.7%) and 0 (0%), respectively, and the median length of hospitalisation was 6.5 and 7.5 days in the long-term group and short-term group, respectively (P = 0.32, P = 0.88).

    Conclusion: Long-term corticosteroid use in the management of acute COPD exacerbation was significantly associated with fewer 180 days re-admission. The duration of corticosteroid use remains controversial, and further studies are recommended to assess the relationship between patient profile and adherence to therapy post-discharge with re-exacerbation.

    The antimetabolite, 5-fluorouracil is widely used in the treatment of cancers. Although its toxic effects on testis causing germinal epithelial sloughing, tubular atrophy and generation of multinucleated cells were reported, its effect on spermatogenesis has not been studied. Hence the present study was conducted to evaluate the effects of 5-fluorouracil on epididymal sperm count. Male Wistar rats were employed in the study (n=5 per group). The animals were injected (i.p) with five consecutive doses of 5-fluorouracil (10, 20, 30mg/kg b.w) at an interval of 24h and the control with 0.1ml-distilled water. Samples were obtained at 14, 35, 42 and 70 days after injection. Rats were sacrificed, a laparatomy was performed and epididymes were collected in 1ml phosphate buffered saline (pH 7.2), minced, filtered and stained with 1% aqueous eosin Y. An aliquot was taken in leucocyte pipette, diluted with phosphate buffered saline and sperm count was done as per the standard procedure. Data were analyzed by Mann Whitney U test. The results of this study revealed that 5 - fluorouracil significantly decreased the sperm count in a dose- and time-dependent manner.

    Fractal dimensions (FDs) are frequently used for summarizing the complexity of retinal vascular. However, previous techniques on this topic were not zone specific. A new methodology to measure FD of a specific zone in retinal images has been developed and tested as a marker for stroke prediction. Higuchi's fractal dimension was measured in circumferential direction (FDC) with respect to optic disk (OD), in three concentric regions between OD boundary and 1.5 OD diameter from its margin. The significance of its association with future episode of stroke event was tested using the Blue Mountain Eye Study (BMES) database and compared against spectrum fractal dimension (SFD) and box-counting (BC) dimension. Kruskal-Wallis analysis revealed FDC as a better predictor of stroke (H = 5.80, P = 0.016, α = 0.05) compared with SFD (H = 0.51, P = 0.475, α = 0.05) and BC (H = 0.41, P = 0.520, α = 0.05) with overall lower median value for the cases compared to the control group. This work has shown that there is a significant association between zone specific FDC of eye fundus images with future episode of stroke while this difference is not significant when other FD methods are employed.

    The aim of this study is to evaluate the psychometric properties of the translated Malay language version of TZO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire in preschool children. Preterm children and term children aged between two and five years were enrolled into the study. The Malay language version of TAPQOL and a set of questions regarding the child's health status were answered by the caregivers. The internal consistency, Spearman's correlation coefficients and principal component analysis (PCA) with Varimax rotation and Mann-Whitney U test for group comparison were employed to evaluate the psychometric properties of this instrument. A total of 258 children (120 preterm children and 138 term children) were recruited to this study with a response rate of 94%. All (sub)domains except one had Cronbach's α coefficients of more than .7. The Spearman's correlation coefficients between 12 subdomains were generally low. PCA supported the structural unidimensionality of the items in the instrument. Preterm children had lower quality of life scores than that of term children. Malay version of TAPQOL has multidimensional construct. It is a reliable and valid instrument for preschool children, with almost similar psychometric properties to the original version.

    Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Result showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivors' health and quality of life.

    Sleep disordered breathing (SDB) is increasingly being diagnosed in children. However, there is no prevalence study done in Malaysia. The study objective was to evaluate the prevalence of SDB symptoms based on parental reports and associated risk factors among Malay school children aged 6 to 10 years old in a primary school using a translated University Michigan Paediatric Sleep Questionnaire (Malay UM-PSQ). The children whose parents responded to the questionnaire and consented were examined, documenting height, weight, skin fold thickness, neck and abdominal circumference, tonsillar size, nostril examination and presence of micrognathia or retrognathia. There were 550 respondents. The prevalence of parental report of SDB symptoms was 14.9 % (95 % CI 11.9, 17.9). Two hundred and eighty-five (51.8%) school children were males with mean age of 8.5 years (SD 1.1). The associated risk factors for SDB symptoms are male, obesity, large neck and waist circumference, positive history of asthma, history of recurrent tonsillitis, enlarged tonsil (> 4+) and enlarged nasal turbinate. Multivariate analysis showed that male gender is the only significant independent risk factor of SDB symptoms

    The aim of this study was to evaluate the antimicrobial activity of a new experimental nano-hydroxyapatite epoxy resin-based sealer (Nanoseal) with several other commercially available sealers; AH26, Tubliseal, Sealapex and Roekoseal against Enterococcus faecalis, Pseudomonas aeruginosa, Streptococcus mutans, Streptococcus sobrinus and Escherichia coli for up to 7 days. Agar diffusion was used in this study. Fifty Muller-Hinton agar plates were prepared and divided into five experimental groups (n = 10), for each micro-organism. Another 10 agar plates were used as positive and negative controls. Endodontic sealers were tested against each micro-organism. Inhibition zones produced were recorded. The results of this study showed that all test materials exhibited inhibition zones towards the tested micro-organisms for 7 days except for Roekoseal, which showed no inhibition zones. Nanoseal and AH26 exhibited similar zones of inhibition. Significant difference was found between Nanoseal and the other tested sealers (P < 0.001).

    Heavy metals, particularly cadmium, lead, and arsenic, constitute a significant potential threat to human health. This study was conducted to determine the levels of cadmium, lead, and arsenic in nail samples from farmers at Muda Agricultural Development Authority (MADA), Kedah, Malaysia, and evaluate factors that can contribute to their accumulations. A total of 116 farmers participated in this study. Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze concentration of heavy metals in the nail samples and questionnaires were given to participants to get demographic, health status, and their agricultural activities data. In this paper, the level of heavy metals was within the normal range and varies according to demographic factors. We found that there were significant correlations between working period with level of lead and arsenic (r=0.315 and r=0.242, resp., P<0.01) and age with lead level (r=0.175, P<0.05). Our findings suggested that agricultural activities could contribute to the accumulation of heavy metals in farmers. Hence, the control of environmental levels of and human exposure to these metals to prevent adverse health effects is still an important public health issue.

    OBJECTIVE: Safety of fasting in Ramadan for diabetic patients is not clearly known. The aim of this study was to determine the effects of fasting on glycemic excursions by continuous glucose monitoring system (CGMS).
    MATERIALS AND METHODS: This pilot, observational study conducted in the Endocrine Research Center, Mashhad University of Medical Sciences, Mashhad, IRAN, in Ramadan 2008. Seventeen well controlled patients with diabetes type 2 who were taking oral agents underwent 72 hour monitoring of glycemic excursions by CGMS one month before Ramadan and during Ramadan. The extent and duration of hyperglycemic and hypoglycemic events were evaluated and compared.
    RESULTS: A significant reduction in hyperglycemic events was observed during Ramadan. The extent and duration of hypoglycemic events was not significantly different between two states (Ramadan and before). A significant increase in number of hypoglycemic events in Ramadan was found in patients who take sulfonylurea compared with those who take only metformin.
    CONCLUSION: Fasting in Ramadan can be safe for well controlled patients with type 2 diabetes.

    This paper aims to evaluate the effect of splinting during implant impression. A master model with two fixtures at the sites of 45 and 47 was used. 20 impressions were made for all four techniques: (A) indirect; (B) direct, unsplinted; (C) direct, splinted; and (D) direct, splinted, sectioned, and re-splinted. Splinting was undertaken with autopolymerizing acrylic resin (AAR). Horizontal distance between fixtures was compared using a digital caliper. The difference in distance were analysed with one-way ANOVA. Group A showed a significantly lowest accuracy among all techniques (p < or = 0.05). There was no significant difference of accuracy among the groups using direct techniques (p > or = 0.05). Group D was more accurate compared to group B and C. We conclude that splinting of impression copings would be beneficial to obtain an accurate impression.

    Community pharmacies are valued for their potential role in the management of common ailments. This cross-sectional study aimed to document the management of diarrhoea by community pharmacies in 3 cities in Pakistan. Visits were performed to 371 randomly selected pharmacies to request advice for a simulated paediatric case of diarrhoea. The pharmacy's management was scored on a checklist including history taking and provision of advice and information. Customers were served by a salesperson in 97.3% of visits and by a pharmacist in only 2.2%. Medication was dispensed in 77.1% of visits. Of the medications dispensed, 58.7% were antiamoebics, 14.0% antibiotics and 18.9% antidiarrhoeals; only 8.4% were oral rehydration salts. None of the regimens matched with a standard prescription. The dosage regimen was explained to the customer in only 52.6% of cases. Drug safety, unqualified personnel, lack of history taking, inappropriate treatment and lack of counselling are concerns to be addressed.

    Dengue is the most important mosquito-borne viral disease. In the absence of specific drugs or vaccines, control focuses on suppressing the principal mosquito vector, Aedes aegypti, yet current methods have not proven adequate to control the disease. New methods are therefore urgently needed, for example genetics-based sterile-male-release methods. However, this requires that lab-reared, modified mosquitoes be able to survive and disperse adequately in the field.

    The genotoxic effects of increasing concentrations (below lethal concentration [LC₅₀]) of cadmium ([Cd] 0.1, 1 and 10 mg/L), copper ([Cu] 0.2, 2 and 20 mg/L) and zinc ([Zn] 0.5, 5 and 50 mg/L) on Chironomus kiiensis were evaluated using alkaline comet assay after exposure for 24 h. Both the tail moment and the olive tail moment showed significant differences between the control and different concentrations of Cd, Cu and Zn (Kruskal-Wallis, p < 0.05). The highest concentration of Cd was associated with higher DNA damage to C. kiiensis larvae compared with Cu and Zn. The potential genotoxicity of these metals to C. kiiensis was Cd > Cu > Zn.

    BACKGROUND: Transtheoretical Model of change has been used successfully in promoting behaviour change.

    OBJECTIVE: To examine the relationships between health-related quality of life (HRQoL) scores with the stages of change of adequate physical activity and fruit and vegetables intake.

    DESIGN: This was a cross-sectional study conducted among employees of the main campus and Engineering campus of Universiti Sains Malaysia (USM) during October 2009 and March 2010.

    MAIN VARIABLES STUDIED: Data on physical activity and fruit and vegetable intake was collected using the WHO STEPS instrument for chronic disease risk factors surveillance. The Short Form-12 health survey (SF-12) was used to gather information on participants' HRQoL. The current stages of change are measured using the measures developed by the Pro-Change Behaviour Systems Incorporation.

    STATISTICAL ANALYSIS: One way ANOVA and its non-parametric equivalent Kruskal-Wallis were used to compare the differences between SF-12 scores with the stages of change.

    RESULTS: A total of 144 employees were included in this analysis. A large proportion of the participants reported inadequate fruits and vegetable intake (92.3%) and physical activity (84.6%). Mean physical and mental component scores of SF-12 were 50.39 (SD = 7.69) and 49.73 (SD = 8.64) respectively. Overall, there was no statistical significant difference in the SF-12 domains scores with regards to the stages of change for both the risk factors.

    CONCLUSIONS: There were some evidence of positive relationship between stages of change of physical activity and fruit and vegetable intake with SF-12 scores. Further studies need to be conducted to confirm this association.
