Dengue is a global public health problem. The Dengue Virus (DENV) serotypes are transmitted by an Aedes aegypti mosquito. Vector control is among the primary methods to prevent the disease, especially in tropical countries. This study aimed to analyze the spatial distribution of dengue and its relationship with social inequalities using spatial modelling. An ecological study with temporal and spatial analysis was conducted in the state of Sergipe, Northeast Brazil, over a period of 18 years. Spatial modelling was used to determine the influence of space on dengue incidence and social inequalities. The epidemic rates in 2008, 2012, and 2015 were identified. Spatial modelling explained 40% of the influence of social inequalities on dengue incidence in the state. The main social inequalities related to the occurrence of dengue were the percentage of people living in extreme poverty and inadequate sanitation. The epidemic situation even increased the risk of dengue in the population of the state of Sergipe. These results demonstrate the potential of spatial modelling in determining the factors associated with dengue epidemics and are useful in planning the intersectoral public health policies.

UNSTRUCTURED The current outbreak of coronavirus disease 2019 (COVID-19) caused by the novel coronavirus named SARS-CoV-2 has been a major global public health problem threatening many countries and territories. Mathematical modelling is one of the non-pharmaceutical public health measures that plays a crucial role for mitigating the risk and impact of the pandemic. A group of researchers and epidemiologists have developed a machine learning-powered inherent risk of contagion (IRC) analytical framework to georeference the COVID-19 with an operational platform to plan response & execute mitigation activities. This framework dataset provides a coherent picture to track and predict the COVID-19 epidemic post lockdown by piecing together preliminary data on publicly available health statistic metrics alongside the area of reported cases, drivers, vulnerable population, and number of premises that are suspected to become a transmission area between drivers and vulnerable population. The main aim of this new analytical framework is to measure the IRC and provide georeferenced data to protect the health system, aid contact tracing, and prioritise the vulnerable.

Anemia is a global public health problem. The prevalence of anemia among different ages, genders or ethnic groups must be clarified in order to solve problems. This study proposed to determine the prevalence and factors related to anemia among the Muslim school-age population in Nakhon Si Thammarat, Thailand. Socio-demographic and anthropometric data were collected by a structured questionnaire. Blood samples were collected from 200 school-age subjects. The thalassemia screening was performed with KKU-OF and KKU-DCIP reagents. The prevalence of anemia in this study was 36.5%, divided into males and females, 33.3% and 39.1%, respectively. The means of Hb, Hct, MCV, MCH, and MCHC in the anemic group were significantly lower. The positive results for KKU-OF or KKU-DCIP or both were 15.0%, 2.5%, and 1.0%, respectively. The result of positive OF test was a significantly independent factor for anemia. The number of family members was 5 to 7 and more than 7 persons are related factors for anemia in this study. In summary, the contribution of thalassemia and socio-economic factor are associated factors to anemia in this population. These findings should be addressed in public health strategies for the control of anemia of school-aged Muslims in the region.

Abstract Hyperendemic circulation of all four Dengue virus (DENV) serotypes is a severe global public health problem, so any vaccine or therapeutics should be able to target all four of them. Cells of hemopoietic origin are believed to be primary sites of DENV replication. This study aimed to identify potential host miRNAs that target 3' UTR of all 4 DENV serotypes, thereby directly regulating viral gene expression or indirectly modulating the host system at different virus infection steps. We used four prediction algorithms viz. miRanda, RNA22, RNAhybrid, and StarMir for predicting miRNA, targeting 3'UTR of all four DENV serotypes. Statistically, the most significant miRNA targets were screened based on their Log10 P-value (> 0.0001) of GO term and KEGG pathway enrichment analysis. The intersection test of at least three prediction tools identified a total of 30 miRNAs, which could bind to 3'UTR of all four DENV serotypes. Of the 30, eight miRNAs were of hematopoietic cell origin. GO term enrichment and KEGG analysis showed four hemopoietic origin miRNAs target genes of the biological processes mainly involved in the innate immune response, mRNA 3'-end processing, antigen processing, and presentation and nuclear-transcribed mRNA catabolic process.

Medication error is a major cause of morbidity and mortality in medical profession . There is an increasing recognition that medication errors are causing a substantial global public health problem, as many result in harm to patients and increased costs to health providers.Anaesthesia is now safe and routine, yet anaesthetists are not immune from making medication errors and the consequences of their mistakes may be more serious than those of doctors in other specialties. Steps are being taken to determine the extent of the problem of medication error in anaesthesia. In this review, incidence, types, risk factors and preventive measures of the medication errors are discussed in detail.Journal of Bangladesh Society of Anaesthesiologists 2014; 27(1): 31-35

Background: Zoonotic spillover from animal reservoirs is responsible for a significant global public health burden, but the processes that promote spillover events are poorly understood in complex urban settings. Endemic transmission of Leptospira, the agent of leptospirosis, in marginalised urban communities occurs through human exposure to an environment contaminated by bacteria shed in the urine of the rat reservoir. However, it is unclear to what extent transmission is driven by variation in the distribution of rats or by the dispersal of bacteria in rainwater runoff and overflow from open sewer systems. <br /><br />Methods: We conducted an eco-epidemiological study in a high-risk community in Salvador, Brazil, by prospectively following a cohort of 1,401 residents to ascertain serological evidence for leptospiral infections. A concurrent rat ecology study was used to collect information on the fine-scale spatial distribution of ‘rattiness’, our proxy for rat abundance and exposure of interest. We developed and applied a novel geostatistical framework for joint spatial modelling of multiple indices of disease reservoir abundance and human infection risk. <br /><br />Results: The estimated infection rate was 51.4 (95\%CI 40.4, 64.2) infections per 1,000 follow-up events. Infection risk increased with age until 30 years of age and was associated with male gender. Rattiness was positively associated with infection risk for residents across the entire study area, but this effect was stronger in higher elevation areas (OR 3.27 95\%CI 1.68, 19.07) than in lower elevation areas (OR 1.14 95\%CI 1.05, 1.53). <br /><br />Conclusions: These findings suggest that, while frequent flooding events may disperse bacteria in regions of low elevation, environmental risk in higher elevation areas is more localised and directly driven by the distribution of local rat populations. The modelling framework developed may have broad applications in delineating complex animal-environment-human interactions during zoonotic spillover and identifying opportunities for public health intervention.<br /><br />Funding: This work was supported by the Oswaldo Cruz Foundation and Secretariat of Health Surveillance, Brazilian Ministry of Health, the National Institutes of Health of the United States (grant numbers F31 AI114245, R01 AI052473, U01 AI088752, R01 TW009504 and R25 TW009338); the Wellcome Trust (102330/Z/13/Z), and by the Fundação de Amparo à Pesquisa do Estado da Bahia (FAPESB/JCB0020/2016).

Background: Pinworm infection remains a global public health problem in Indonesia, with the highest prevalence in primary school–aged children. The government has made helminthiasis control efforts through annual deworming every six months, yet data on the enterobiasis prevalence and its risk factors are still limited. Purpose: This research aimed to determine the role of personal hygiene and anthelmintic or worm medicine consumption in the prevention of enterobiasis among primary school children. Methods: This research employed an analytic observational method with a cross-sectional design. The population used was primary school children in the Public Health Center (PHC) of Kaliwungu area, Kendal District, Central Java Province. The research sample was 150 students from first grade to third grade at 1 Primary Elementary School 1 Kutoharjo. The data sources were obtained from interviews of risk factors and perianal swab examinations. The data were analyzed by a chi-square test and multiple logistic regression. Results: The prevalence of pinworm infection among primary school children remains high (37.33%). The results of the multivariate analysis showed that there are three determinant variables of pinworm infections: not washing hands with soap before eating (p < 0.01; Prevalence Odds Ratio (POR) = 6.47; 95% Confidence Interval [CI] = 2.87 < POR < 14.59); not washing hands with soap after defecation (p = 0.01; POR = 3.36; 95% CI = 1.40 < POR < 8.05); and not consuming anthelmintic drugs within the past six months (p = 0.03; POR = 2.43; 95% CI = 1.08 < POR < 5.50). Conclusion: Hand washing habits and annual deworming are important factors to prevent pinworm infections.

Introduction: Adolescent suicide is a public health problem that has been neglected due to the pandemic and confinement. Objective: To describe the characteristics of adolescent suicide, during the period of confinement due to pandemic in the year 2020 in Ecuador. Method: An observational, descriptive, cross-sectional, retrospective study was carried out, with the information from the database of violent deaths of the Ministry of Government, from March 17 to September 13, which lasted through the state of emergency. The analysis was carried out by province, sex, age, suicide method and frequency in days after the event occurred. The suicide mortality rate (per 100,000 inhabitants) was estimated for each province. Results: During confinement due to a state of emergency in 2020 in Ecuador, 97 suicides were registered among adolescents between 10 and 19 years of age. The highest number was estimated in males between 15 and 19 years of age, with the most frequent age being 19. The most frequent day of removal of corpses was on Mondays, and the preferred mode of suicide was by hanging with 81 reported cases. followed by intoxication and poisoning. Conclusions: No increases were found in the suicide mortality rate during the state of emergency in 2020. However, it must be considered that the context of COVID-19 has increased the burden of psychological suffering, which may lead adolescents to think about suicide.
