Objective: Utilizing Mendelian Randomization, this study employs Single Nucleotide Polymorphisms (SNPs) as instrumental variables to explore the causal relationships between bibulosity, smoking, and Primary Open Angle Glaucoma (POAG). Methods: GWAS data for bibulosity, smoking, and POAG were obtained from the Social Science Genetic Association Consortium website and the IEU OpenGWAS Project website, respectively. Using a P-value threshold of −8, a linkage disequilibrium coefficient (r2) of 0.001, and a linkage disequilibrium region width of 10,000 kb, the data were aggregated, resulting in 6 SNPs for bibulosity and 253 SNPs for smoking. Three regression models, MR-Egger, Weighted Median Estimator (WME), and Random-Effects Inverse-Variance Weighted (IVW) were applied to analyze the causal impact of bibulosity and smoking on POAG. Results: The GWAS data for alcohol consumption and smoking were derived from European populations, while the GWAS data for Primary Open-Angle Glaucoma (POAG) were sourced from East Asian populations, with no gender restrictions. Analysis using three different regression models revealed that neither excessive alcohol consumption nor smoking significantly increased the risk of developing POAG. Specifically, the odds ratios with 95% confidence intervals for the alcohol consumption group were 0.854 (0.597 - 1.221) in MR-Egger regression, 0.922 (0.691 - 1.231) in WME regression, and 0.944 (0.711 - 1.252) in IVW regression. For the smoking group, the odds ratios were 1.146 (0.546 - 2.406) in MR-Egger regression, 0.850 (0.653 - 1.111) in WME regression, and 0.939 (0.780 - 1.131) in IVW regression. Given the significant heterogeneity in the SNPs associated with smoking, the focus was primarily on the results from the IVW regression model. Conclusion: Alcohol consumption and smoking are not significant risk factors for the development of POAG. 展开更多

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome). 展开更多

Background: The use of drugs for purposes other than those for which they are meant to be used or in excess amounts. Psychoactive drugs are some of the drugs more commonly abused, also, antibiotics and other medications too can be misused. Drug abuse and misuse can lead to serious social, medical and emotional harm to the patients, and antibiotic resistance that makes treatment harder are also likely complications. Method: Patients in both male and female wards of the Orthoepaedics Department of ATBUTH, Bauchi were interviewed using a structured questionnaire and their responses were recorded and data were analyzed using the SPSS version 29. Results: A total of 112 patients were interviewed, 76 males and 36 females. Thirty-two (28.6%) patients had taken various kinds of unprescribed medications while on admission: 9 patients had taken unprescribed tramadol, 4 patients had taken codeine, 6 Ampiclox, 5 flagyl and about 8 patients had taken different kinds of traditional medications while on admission. Among the 32 patients, 23 (72%) are aged less than 30 years, 5 (16%) are aged between 30 and 50 years and 4 (12%) are aged above 50 years. Sixteen (50%) had such medications brought to them by relatives or friends, 10 (30%) were given by other patients on admission, 5 (15%) brought or bought the drugs by themselves while 1 (5%) were given by a non-clinical staff of the hospital. Conclusion: Drug misuse and abuse is a very serious, deleterious practice with destructive consequences in its wake, such consequences as drug dependency with all its antecedent effects, antibiotic resistance and difficulties in controlling/managing infections are but a few. So, it’s very important to both educate patients about these terrible practices and cope with the spread of them in our wards and hospitals. 展开更多

Social media platforms like Instagram have increasingly become venues for online abuse and offensive comments. This study aimed to enhance user security to create a safe online environment by eliminating hate speech and abusive language. The proposed system employed a multifaceted approach to comment filtering, incorporating the multi-level filter theory. This involved developing a comprehensive list of words representing various types of offensive language, from slang to explicit abuse. Machine learning models were trained to identify abusive messages through sentiment analysis and contextual understanding. The system categorized comments as positive, negative, or abusive using sentiment analysis algorithms. Employing AI technology, it created a dynamic filtering mechanism that adapted to evolving online language and abusive behavior. Integrated with Instagram while adhering to ethical data collection principles, the platform sought to promote a clean and positive user experience, encouraging users to focus on non-abusive communication. Our machine-learned models, trained on a cleaned Arabic language dataset, demonstrated promising accuracy (75.8%) in classifying Arabic comments, potentially reducing abusive content significantly. This advancement aimed to provide users with a clean and positive online experience. 展开更多

Background: Globally, it is estimated that more than 800,000 individuals die by suicide each year, making suicide one of the biggest causes of death worldwide. Additionally, suicide kills far more males than women, more so in developing regions that are characterized by economic distress due to low income. Although the number of suicide cases has been seen to increase from 2013 to date, limited studies provide information on the factors influencing the trend. Therefore, this study aimed at investigating the prevalence of suicidal ideation and factors associated with suicide in males in selected compounds of Lusaka. Methods: The study used an analytical quantitative cross- sectional study design that involved 367 men in Mtendere and Kaunda Square townships in Lusaka district, Zambia. A structured questionnaire was used to collect data from participants, which was analyzed using Statistical Package for Social Sciences (SPSS) version 26.0. The Chi-square, Fisher’s exact test and Wilcoxon rank sum tests were used to test relationships among variables at a five percent level of significance. Ethical approval and clearance was obtained from the National Health Research Authority. Results: Participants had a median age of 29 years (IQR, 27 - 32 years), 216 (58.9%) were single and 278 (75.8%) attained tertiary education. Under a quarter, 75 (20.4%) reported suicide ideations, and 97 (26.4%) reported low social support. For most participants, 347 (94.7%) experienced at least one stressful life event, and 359 (97.8%) experienced severe levels of stress. Under half, 170 (46.3%) were alcohol dependent, while 54 (14.7%) used alcohol harmfully. Suicide ideation was significantly associated with marital status (p Conclusion: Suicide ideation is relatively high among men in Mtendere and Kaunda Square townships, mainly influenced by marital status, education level, social support, stressful events alcohol abuse. Efforts must be channeled towards suicide awareness campaigns, and establishment of supportive environments in health facilities which can make it easy for men to open up about their struggles. 展开更多
