Chemicals usage has been reported as the cause of accidents in a laboratory. Those accidents have caused many injuries, even fatality in many sectors, one of which happened in the University Teaching Laboratory. Accidents usually happen because of unsafe behavior, while unsafe behavior is caused by bad safety perceptions. This paper investigates the correlation of perceptions and behavior in University Teaching Laboratory. The result measured by regression analysis to find out the relationship between two variables showed that there is a strong relationship between perceptions and behavior. Therefore, safe behavior can be created through creating good perception.

Introduction: Children living in orphanages tend to be neglected and may be malnourished. This study assessed the socio-economic background and nutritional status of children living in an orphanage in Dhaka city, Bangladesh. Methods: A cross-sectional study was conducted among the children in Sir Salimullah Muslim Orphanage, Dhaka from January to November 2014. Systematic sampling was adopted to collect data from 232 children using a semi-structured questionnaire. Anthropometric measurements of the children were taken and the WHO reference growth chart was used to determine the children’s nutritional status. Weight-for-age was categorised by mild, moderate and severe malnutrition. The Pearson Chi-square test was performed to determine the association between the extent of malnutrition and socio-demographic characteristics of the children. Results: The majority of the children (60.3%) in the orphanage were malnourished, with mild, moderate and severe malnourished being 43.1%, 16.8% and 0.4%, respectively. Malnutrition was higher among the boys than girls in the age group of 15-18 years. The orphans suffered significantly (P<0.05) from malnutrition compared to those, who had at least one parent alive. Conclusion: Malnutrition is highly prevalent among children and adolescents under residential care and needs to be addressed. In particular, early identification and intervention can improve the quality of nutritional status of the urban orphanage population. An investigation with a large sample is highly desirable to explore the severity of the problem in the national context.

Background: Atrial tachycardia poses challenges in patient management due to the associated risks of stroke and systemic embolism. While anticoagulation is recommended in atrial fibrillation (AF), its role in atrial tachycardia remains less defined. This prospective study aimed to evaluate the efficacy and safety of apixaban, a direct oral anticoagulant, in individuals diagnosed with left-sided atrial tachycardias. Methods: Patients diagnosed with left-sided atrial tachycardia (n = 439) were observed over 3 years. Baseline characteristics, medication regimens, and clinical outcomes were assessed. Apixaban-treated individuals (n = 213) received standard or reduced dosages, while the control group (n = 226) received standard care. Primary outcomes included stroke, systemic embolism, bleeding, and mortality rates. Results: Baseline characteristics were comparable between groups. The apixaban cohort showed a lower incidence of stroke (7.0% vs. 9.3%, p = 0.027) and decreased all-cause mortality (11.7% vs. 12.8%, p = 0.012) compared to controls.No significant differences were found in major bleeding or systemic embolization between groups. Conclusion Apixaban demonstrated a potential benefit in reducing stroke and mortality rates in patients with leftsided atrial tachycardia. While requiring further validation, these findings suggest a potential role for apixaban in anticoagulation strategies for atrial tachycardia management.

BACKGROUND: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options. METHODS: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence. All randomized controlled trials delineating the outcomes of surgical versus conservative treatments for acute undisplaced or minimally-displaced scaphoid fractures were included and then evaluated using scoring tools: Cochrane risk of bias tool and PEDro scale. Data were pooled using random-effects models with standard mean differences for continuous outcomes and risk ratios for dichotomous variables. RESULTS: The search yielded 339 potentially related articles, further trimmed down to eight studies based on the eligibility criteria. The meta-analysis revealed that surgical treatment resulted in significantly better functional outcomes than conservative treatment. Furthermore, surgery resulted in the prevention of delayed union of fractures and reduction of time needed to return to work. CONCLUSIONS: While four studies reported advantages of surgical treatment, evidence was insufficient to provide a definitive conclusion that surgery is a better option. Due to the significant limitations with respect to certain variables, the superiority of one method to the other could not be established.

Therapeutic dentin regeneration remains difficult to achieve, and a majority of the attention has been given to anabolic strategies to promote dentinogenesis directly, whereas, the available literature is insufficient to understand the role of inflammation and inflammatory complement system on dentinogenesis. The aim of this study is to determine the role of complement C5a receptor (C5aR) in regulating dental pulp stem cells (DPSCs) differentiation and in vivo dentin regeneration. Human DPSCs were subjected to odontogenic differentiation in osteogenic media treated with the C5aR agonist and C5aR antagonist. In vivo dentin formation was evaluated using the dentin injury/pulp-capping model of the C5a-deficient and wild-type mice. In vitro results demonstrate that C5aR inhibition caused a substantial reduction in odontogenic DPSCs differentiation markers such as DMP-1 and DSPP, while the C5aR activation increased these key odontogenic genes compared to control. A reparative dentin formation using the C5a-deficient mice shows that dentin regeneration is significantly reduced in the C5a-deficient mice. These data suggest a positive role of C5aR in the odontogenic DPSCs differentiation and tertiary/reparative dentin formation. This study addresses a novel regulatory pathway and a therapeutic approach for improving the efficiency of dentin regeneration in affected teeth.

Objective To assess the knowledge on Zika virus infection among healthcare providers (doctors) in Aceh province, Indonesia. Methods A self-administered internet based survey was conducted from 3 May to 3 June 2016 among the members of doctor organizations in Aceh province. A set of validated, pre-tested questionnaire was used to measure knowledge regarding Zika infection and to collect a range of explanatory variables. A two-steps logistic regression analysis was employed to assess the association of participants' demographic, workplace characteristics and other explanatory variables with the knowledge. Results A total of 442 participants included in the final analysis and 35.9% of them (159) had a good knowledge on Zika infection. Multivariate model revealed that type of occupation, type of workplace, availability of access to medical journals and experience made Zika disease as differential diagnose were associated with knowledge on Zika infection. In addition, three significant source of information regarding Zika were online media (60%), medical article or medical news (16.2%) and television (13.2%). Conclusion The knowledge of the doctors in Aceh regarding Zika infection is relatively low. Doctors who have a good knowledge on Zika infection are more confident to established Zika disease as differential diagnosis in their clinical setting. Therefore, such program to increase healthcare providers' knowledge regarding Zika infection is needed to screen potential carriers of Zika infection.

Introduction: Methotrexate (MTX), Moringa oleifera (MO), and Andrographis paniculata (AP) have been reported to have anti-hyperglycemic, antioxidative, and anti-inflammatory effects in diabetic rats. This study aims to investigate the single and combination effects of MTX, MO, and AP on random blood glucose levels, interleukin-6 (IL-6) levels, and trabecular density in diabetic rats. Methods: A total of 49 male rats were divided into seven groups, namely one control group and six diabetes mellitus (DM) groups. All rats in the DM groups were injected with streptozotocin-nicotinamide (STZ-NA) intraperitoneally. In addition, the DM groups were administered with a placebo daily (DG), a single dose of 500 mg/kg BW MO daily (DG+MO), a single dose of 500mg/kg BW AP daily (DG+AP), a single dose of 7 mg/kg BW MTX once a week (DG+MTX), a combination of MTX+MO, and a combination MTX+AP, respectively. The experiment lasted for 28 days. On day 29, the right and left femur of the rats were collected for IL-6 examination (ELISA) and histopathological analysis. Results: IL-6 expression levels were significantly lower in diabetic rats treated with single and combination of MTX, MO, and AP compared to untreated diabetic rats (p < 0.05). However, the random blood glucose levels and trabecular density between treated and untreated diabetic rats were not significantly different (p < 0.001, p = 0.152). In addition, IL-6 levels were not correlated with trabecular density in all groups (r = -0.057, p = 0.722). Conclusion: Single doses of MTX, MO leaf extract, and AP leaf extract could suppress IL-6 expression in the femur tissue in diabetic rats. However, the IL-6 expression was not correlated with trabecular density although it significantly affected blood glucose levels in this study.
