The impact of sociodemographic, health status and resources, macroeconomic, and environmental factors on infant mortality rates in Qatar, Kingdom of Saudi Arabia, and the United Arab Emirates.

OBJECTIVES: This study aims to study the impact of sociodemographic (SD), health status and resources (HSR), macroeconomic (ME), and Environmental (EV) factors on the infant mortality rate (IMR) in Qatar, Kingdom of Saudi Arabia (KSA), and the United Arab Emirates (UAE) and from 1990 to 2022. DESIGN: A retrospective time-series study employing yearly data was conducted. A generalized least squares model was utilized to construct an exploratory model of IMR determinants for each country. RESULTS: In SD, the risk of IMR may be increased with a higher crude birth rate, adolescent fertility rate, and married women percentage. In HSR, immunization coverage shows a significant effect in preventing neonatal diseases and reducing IMR. In ME, the effect of parents' employment seems contradicted among the three countries. In EV, greenhouse emissions have also had contradictory effects among the three countries, suggesting a complex relationship with IMR. Some were consistent with global findings, whereas others contradicted the prevailing narrative. CONCLUSIONS: This study highlights the need for tailored public health interventions addressing socio-demographic, healthcare, and environmental contexts to effectively reduce IMR and enhance infant health outcomes.

Investigating the Significant Individual Historical Factors of Driving Risk Using Hierarchical Clustering Analysis and Quasi-Poisson Regression Model.

Driving risk varies substantially according to many factors related to the driven vehicle, environmental conditions, and drivers. This study explores the contributing historical factors of driving risk with hierarchical clustering analysis and the quasi-Poisson regression model. The dataset of the study was collected from two sources: naturalistic driving experiments and self-reports. The drivers who participated in the naturalistic driving experiment were categorized into four risk groups according to their near-crash frequency with the hierarchical clustering method. Moreover, a quasi-Poisson model was used to identify the essential factors of individual driving risk. The findings of this study indicated that historical driving factors have substantial impacts on individual risk of drivers. These factors include the total number of miles driven, the driver's age, the number of illegal parking (past three years), the number of over-speeding (past three years) and passing red lights (past three years). The outcome of the study can help transportation officials, educators, and researchers to consider the influencing factors on individual driving risk and can give insights and provide suggestions to improve driving safety.

Vaginal rhinosporidiosis: a case report.

The female genital tract is an extremely rare site for Rhinosporidiosis. Here we described a 13 year old girl who presented with a slow growing polypoid fleshy mass in the posterior vaginal wall near the orifice for 6 months with scanty bleeding from the mass. The girl was admitted to hospital with profuse watery vaginal discharge. Excision of the mass was followed by histopathological examination which confirmed the diagnosis Rhinosporidiosis.

A dataset on the prevalence and associated risk factors for mental health problems among female university students in Bangladesh.

The data presented here relate to the article with the following title, "Prevalence and associated risk factors for mental health problems among female university students during COVID-19 pandemic: A cross-sectional study findings from Dhaka, Bangladesh" [1]. This article provides a dataset on the prevalence of psychological distress among 451 female university students during the ongoing COVID-19 pandemic. We collected their responses from October 15, 2021, to January 15, 2022, using Google survey tools (Google Forms). A structured questionnaire was prepared, consisting of sociodemographic variables and their association with mental health problems. Three psychometric scales, UCLA-3, GAD-7, and PHQ-9, were applied to measure disorders of loneliness, anxiety, and depression, respectively. We performed the statistical analysis using IBM SPSS (v. 25.0). Each respondent gave their electronic consent for the study, and anonymized data were published. Hence, policymakers of government and non-government groups may utilize the data to create a variety of initiatives to support the mental health of female university students from Dhaka, Bangladesh.

Repositioning potentials of smallpox vaccines and antiviral agents in monkeypox outbreak: A rapid review on comparative benefits and risks.

Background and aims: There is a sought for vaccines and antiviral agents as countermeasures for the recent monkeypox outbreak. Here, we aimed to review and discuss the repurposing potentials of smallpox vaccines and drugs in monkeypox outbreaks based on their comparative benefits and risks. Therefore, we conducted this rapid review and discussed the repurposing potentials of smallpox vaccines and drugs in monkeypox infection. Methods: Here, we searched Google Scholar and PubMed for relevant information and data. We found many articles that have suggested the use of smallpox vaccines and antiviral drugs in monkeypox outbreaks according to the study findings. We read the relevant articles to extract information. Results: According to the available documents, we found two replication-competent and one replication-deficient vaccinia vaccines were effective against Orthopoxvirus. However, the healthcare authorities have authorized second-generation live vaccina virus vaccines against Orthopoxvirus in many countries. Smallpox vaccine is almost 85% effective in preventing monkeypox infection as monkeypox virus, variola virus, and vaccinia virus are similar. The United States and Canada have approved a replication-deficient third-generation smallpox vaccine for the prevention of monkeypox infection. However, the widely used second-generation smallpox vaccines contain a live virus and replicate it into the human cell. Therefore, there is a chance to cause virus-induced complications among the vaccinated subjects. In those circumstances, the available Orthopoxvirus inhibitors might be a good choice for treating monkeypox infections as they showed similar efficacy in monkeypox infection in different animal model clinical trials. Also, the combined use of antiviral drugs and vaccinia immune globulin can enhance significant effectiveness in immunocompromised subjects. Conclusion: Repurposing of these smallpox vaccines and antiviral agents might be weapons to fight monkeypox infection. Also, we recommend further investigations of smallpox vaccines and Orthopoxvirus inhibitors in a human model study to explore their exact role in human monkeypox infections.

Spatiotemporal Bayesian networks for malaria prediction.

Targeted intervention and resource allocation are essential for effective malaria control, particularly in remote areas, with predictive models providing important information for decision making. While a diversity of modeling technique have been used to create predictive models of malaria, no work has made use of Bayesian networks. Bayes nets are attractive due to their ability to represent uncertainty, model time lagged and nonlinear relations, and provide explanations. This paper explores the use of Bayesian networks to model malaria, demonstrating the approach by creating village level models with weekly temporal resolution for Tha Song Yang district in northern Thailand. The networks are learned using data on cases and environmental covariates. Three types of networks are explored: networks for numeric prediction, networks for outbreak prediction, and networks that incorporate spatial autocorrelation. Evaluation of the numeric prediction network shows that the Bayes net has prediction accuracy in terms of mean absolute error of about 1.4 cases for 1 week prediction and 1.7 cases for 6 week prediction. The network for outbreak prediction has an ROC AUC above 0.9 for all prediction horizons. Comparison of prediction accuracy of both Bayes nets against several traditional modeling approaches shows the Bayes nets to outperform the other models for longer time horizon prediction of high incidence transmission. To model spread of malaria over space, we elaborate the models with links between the village networks. This results in some very large models which would be far too laborious to build by hand. So we represent the models as collections of probability logic rules and automatically generate the networks. Evaluation of the models shows that the autocorrelation links significantly improve prediction accuracy for some villages in regions of high incidence. We conclude that spatiotemporal Bayesian networks are a highly promising modeling alternative for prediction of malaria and other vector-borne diseases.

Disease Pattern among Children attending Pediatric Outpatient Department in Community Based Medical College Hospital, Bangladesh.

Disease pattern is based on socio-demographic characteristics, comprehensive health care services, and environmental variables like water supply, basic sanitation and housing, illness behavior like quick decision to arrive at health care facility, and treatment behavior like the modality of treatment they receive. The descriptive cross-sectional study was conducted during the period of January 2014 to December 2015. The study was carried out among 310 purposively selected children attended at Pediatric Outpatient department of Community Based Medical College Hospital, Bangladesh. Data were collected by face to face interview of the parents and clinical examination and anthropometric measurement of children using case record form. Mean age of the children was 4.11 years with a SD of 4.35 years, male-female ratio was 1.25:1 with predominance 201(64.84%) of under-five children. The common diseases were 121(39.03%) with Acute Respiratory Infections (ARI), while 43(13.87%) diarrheal diseases, 25(8.06%) each with bronchial asthma and helminthiasis. Other diseases 96(30.97%) include anemia 17(5.48%), urinary tract infection 15 (4.84%), peptic ulcer disease 9(2.90%), enteric fever, oral candidiasis, apthous ulcer of mouth, scabies and vulvovaginitis. Average number of children per family was 2.2 including 251(80.97%) children having sanitary latrine in the family, 297(95.81%) with safe drinking water facilities and 270(87.10%) were fully vaccinated under EPI. More than three fourth 76(24.52%) of the children were underweight, 114(36.77%) were from poor families and 136(43.87%) lived in Kancha house. With the improvement of safe water supply and use of sanitary latrine diseases like diarrhoeal disease and helminthiasis are showing a decreasing trend.

Spatiotemporal Bayesian Networks for Malaria Prediction: Case Study of Northern Thailand.

While a diversity of modeling technique have been used to create predictive models of malaria, no work has made use of Bayesian networks. Bayes nets are attractive due to their ability to represent uncertainty, model time lagged and nonlinear relations, and provide explanations of inferences. This paper explores the use of Bayesian networks to model malaria, demonstrating the approach by creating a village level model with weekly temporal resolution for Tha Song Yang district in northern Thailand. The network is learned using data on cases and environmental covariates. The network models incidence over time as well as evolution of the environmental variables, and captures time lagged and nonlinear effects. Out of sample evaluation shows the model to have high accuracy for one and two week predictions.

The epidemiology of schistosomiasis in Egypt: Ismailia governorate.

A multi-stage stratified sample of 12,515 individuals from 1,941 households in 42 villages in the Ismailia governorate of Egypt were surveyed for schistosomal infection. A subset of 2,390 subjects were surveyed for morbidity by physical and ultrasonographic examination. The prevalence of Schistosoma mansoni infection in rural Ismailia was 42.9% and the geometric mean egg count (GMEC) was 93.3 eggs/gram of stool, with considerable variability between communities. Prevalence and intensity peaked in the 20-30-year-old age group and was higher in males than in females. Prevalence and intensity of S. haematobium was very low: 1.8% and 3.5 ova/10 ml of urine GMEC, respectively. Canal water exposure risk factors for S. mansoni infection were males bathing (odds ratio [OR] = 2.2), females washing clothes (OR = 1.9), and children playing or swimming (OR = 2.3). Presence of in-house piped water supply and latrine lowered infection rates (P < 0.001 and P = 0.002, respectively). Histories of S. mansoni infection (OR = 1.6) or treatment (OR = 1.5) and blood in feces (OR = 3.5) were associated with infection. Hepatomegaly (16.0%) was more frequently detected than splenomegaly (3.6%) by physical examination, with both being more frequent in older age groups. Splenomegaly, but not hepatomegaly, was associated with presence of S. mansoni ova in stools (OR = 1.4) and the community burden of infection (P = 0.02). Ultrasonographically detected hepatomegaly, splenomegaly, and periportal fibrosis (PPF) were detected in 43.0%, 17.4%, and 39.7% of the subjects, respectively. The higher grades of PPF were rare. Ultrasonographically detected splenomegaly, not hepatomegaly, was associated with S. mansoni infection, community burden of infection, and PPF. Risk factors for PPF were the same as for S. mansoni infection. There was a marginal association of PPF with infection and none (P = 0.33) with the intensity of infection in individuals or in the community. We conclude that in rural Ismailia, S. haematobium infection is rare but the prevalence and intensity of infection with S. mansoni is high. The risk of infection is associated with environmentally detected factors and behaviors. Hepatosplenic morbidity attributable to S. mansoni infection is low, presumably because of the favorable effect of wide application of praziquantel therapy.

In vitro α-amylase inhibitory activity and in vivo hypoglycemic effect of methanol extract of Citrus macroptera Montr. fruit.

OBJECTIVE: To investigate the therapeutic effects of methanol extract of Citrus macroptera Montr.fruit in α-amylase inhibitory activity (in vitro) and hypoglycemic activity in normal and glucose induced hyperglycemic rats (in vivo). METHODS: Fruits of Citrus macroptera without rind was extracted with pure methanol following cold extraction and tested for presence of phytochemical constituents, α-amylase inhibitory activity, and hypoglycemic effect in normal rats and glucose induced hyperglycemic rats. RESULTS: Presence of saponin, steroid and terpenoid were identified in the extract. The results showed that fruit extract had moderate α-amylase inhibitory activity [IC50 value=(3.638±0.190) mg/mL] as compared to acarbose. Moreover at 500 mg/kg and 1 000 mg/kg doses fruit extract significantly (P<0.05 and P<0.01 respectively) reduced fasting blood glucose level in normal rats as compared to glibenclamide (5 mg/kg). In oral glucose tolerance test, 500 mg/kg dose significantly reduced blood glucose level (P<0.05) at 2 h but 1 000 mg/kg dose significantly reduced blood glucose level at 2 h and 3 h (P<0.05 and P<0.01 respectively) whereas glibenclamide (5 mg/kg) significantly reduced glucose level at every hour after administration. Overall time effect is also considered extremely significant with F value=23.83 and P value=0.0001 in oral glucose tolerance test. CONCLUSION: These findings suggest that the plant may be a potential source for the development of new oral hypoglycemic agent.

Mass media exposure and its impact on family planning in Bangladesh.

This paper analyses mass media exposure and its effect on family planning in Bangladesh using data from the Bangladesh Demographic and Health Survey (BDHS) 1993-94. The findings indicate that radio and television are two important mass media for disseminating family planning information in Bangladesh. However, access to them and exposure to family planning through them are still limited. Slightly more than 40% (42.1%) of respondents reported that they had heard family planning messages via radio, while 17.2% said television, 8.4% said poster and 5.4% said billboard. Respondent's place of residence, education, economic status, geographical region and number of living children appeared to be the most important variable determining mass media exposure to family planning. Multivariate analysis shows that both radio and TV exposure to family planning messages and ownership of a radio and TV have a significant effect on current use of family planning methods. These factors remain significant determinants of contraceptive use, even after controlling socioeconomic and demographic factors. The study reveals that both socioeconomic development policies and family planning programmes with a special emphasis on mass media, especially radio, may have a significant effect on contraceptive use in Bangladesh. The principal policy challenge is to design communications strategies that will reach the less privileged, rural and illiterate people who are by far the majority in Bangladesh.

Hepatobiliary complications in chronic pancreatitis.

Thirty nine patients undergoing surgery for chronic pancreatitis were investigated for evidence of hepatobiliary disease. In addition to pre-operative assessment by liver function tests, ultrasound, ERCP (in 33) and percutaneous transhepatic cholangiography (in five), all had peroperative liver biopsy. Common bile duct stenosis was diagnosed in 16 (62%) of the 26 patients with successful cholangiography. Features of extrahepatic biliary obstruction were found on biopsy in 11 patients, three of whom showed features of secondary sclerosing cholangitis. No patients had secondary biliary cirrhosis. Three had parenchymal liver disease (cirrhosis, resolving hepatitis and alcoholic hepatitis respectively) and two others had features suggestive of previous alcohol-induced injury. Five (83%) of the patients with clinical jaundice had biopsy features of extrahepatic biliary obstruction, as did eight (67%) with alkaline phosphatase above twice normal and seven (44%) with radiological common bile duct stenosis. Neither alkaline phosphatase rise, nor common bile duct stenosis alone or in combination, were a reliable indication of the need for biliary enteric bypass surgery. Pre-operative liver biopsy may be a valuable adjunct in the assessment of such patients.
