This study, conducted at Quaid-e-Azam Medical College, Bahawalpur, aimed to comprehensively evaluate current students' knowledge, attitudes, and practices concerning cigarette smoking. Employing a web-based cross-sectional observational descriptive study design over the study period from June 15, 2020, to August 1, 2020, a sample of 200 medical students drawn from the first to fifth year was examined using stratified sampling. Data collection involved the distribution of a meticulously designed and pre-tested questionnaire through social media platforms, encompassing inquiries about participants' biodata and research-related topics. The subsequent data analysis utilized Google Spreadsheets, Microsoft Excel, Microsoft Word, and SPSS software to calculate percentages, create graphical representations, construct tables, and apply the chi-square test. The survey findings illuminated a remarkably high level of awareness, with 99% of respondents recognizing the harmful effects of smoking, including elevated cancer risk, and 94% acknowledging its addictive nature. A substantial 93% regarded passive smoking as equally detrimental as active smoking. In comparison, 98.5% were aware of the heightened risk of respiratory illnesses in children exposed to smoking. The majority exhibited a responsible stance towards discouraging smoking, with 90.5% feeling a duty to encourage cessation and 71.5% considering maintaining good health a sufficient incentive to quit. Additionally, 97% concurred that smoking in the presence of children should be avoided. Concerning smoking cessation, 64.5% believed high taxes were effective, and 97.5% deemed public smoking bans effective measures. Notably, 74% thought professional advice had limited influence on a smoker's attitude. Active smokers constituted a mere 20% of the sample, with a mere 2% commencing smoking before age 16 and 10% succumbing to peer pressure or media influence as instigating factors. Furthermore, 13.5% reported exam-related anxiety as a trigger for smoking, and 10% admitted to smoking in the company of non-smokers. Encouragingly, 19.5% expressed a desire to quit, with 5% seeking professional guidance in their cessation attempts. In conclusion, most participants exhibited commendable knowledge and a positive attitude towards cigarette smoking, contributing to a low prevalence of tobacco consumption among them. Nevertheless, the study underscores the need for ongoing improvements through targeted educational initiatives and governmental regulations to further mitigate tobacco use among future healthcare professionals and the broader population.

The Role of Estrogen Therapy as a Protective Factor for Alzheimer's Disease and Dementia in Postmenopausal Women: A Comprehensive Review of the Literature.

The complete cessation of menstruation for 12 months with associated vasomotor symptoms is termed menopause. Apart from playing a role in reproduction, estrogen significantly affects the central nervous system (CNS). Population-based studies highlighted a substantial difference in the prevalence of dementia between men and women, with Alzheimer-associated dementia being more prevalent in women, indicating that estrogen deficiency might be a risk factor for neurodegenerative diseases. Patients with dementia experience a progressive decline in neurocognitive function, beginning with short-term memory loss that progresses to long-term memory loss and the inability to perform everyday activities, leading ultimately to death. There is currently no cure for dementia, so preventing or slowing the disease's progression is paramount. Accordingly, researchers have widely studied the role of estrogen as a neuroprotective agent. Estrogen prevents dementia by augmenting Hippocampal and prefrontal cortex function, reducing neuroinflammation, preventing degradation of estrogen receptors, decreasing oxidative damage to the brain, and increasing cholinergic and serotonergic function. According to the window phase hypothesis, estrogen's effect on preventing dementia is more pronounced if therapy is started early, during the first five years of menopause. Other studies like The Woman's Health Initiative Memory Study (WHIMS) showed unfavorable effects of estrogen on the brain. This review aims to establish an understanding of the currently available data on estrogen's effect on neurodegeneration, namely, dementia and Alzheimer's disease.

Advancements in Inflammatory Bowel Disease: A Narrative Review of Diagnostics, Management, Epidemiology, Prevalence, Patient Outcomes, Quality of Life, and Clinical Presentation.

Inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), is a chronic, immune-mediated disorder that impacts the gastrointestinal tract. Significant advancements in the diagnosis and treatment of IBD have been made during the past few decades, improving patient outcomes. This narrative review aims to provide an overview of recent developments in the diagnosis and treatment of IBD. Both from an evaluative and therapeutic standpoint, the management of IBD has undergone significant change. The standard of treatment for treating UC and CD patients has changed due to several medical developments. These developments include amino-salicylates, immunosuppressants, biological agents, and new therapeutics. The review also addresses the difficulties in applying these developments in clinical practice. Globally, the prevalence of IBD is rising, with Asia among the regions with the highest rates. These environments provide particular difficulties, such as poor disease knowledge, a lack of diagnostic services, and infectious IBD mimics. These issues must be resolved to diagnose and manage IBD in these populations accurately. New imaging modalities and other improvements in diagnostic methods have increased the precision and early identification of IBD. To reduce problems and improve patient outcomes, healthcare professionals treating patients with IBD must work effectively as a team. An extensive summary of current developments in the diagnosis and treatment of IBD is given in this narrative review. It draws attention to the therapeutic possibilities, difficulties, and uncertainties of integrating these developments into clinical practice. By keeping up with these changes, healthcare practitioners can better care for patients with IBD and improve their quality of life.

Comparative efficacy and safety profile of once-weekly Semaglutide versus once-daily Sitagliptin as an add-on to metformin in patients with type 2 diabetes: a systematic review and meta-analysis.

BACKGROUND: The emergence of genetically-modified human proteins and glucagon-like peptide-1 (GLP-1) receptor agonists have presented a promising strategy for effectively managing diabetes. Due to the scarcity of clinical trials focusing on the safety and efficacy of semaglutide as an adjunctive treatment for patients with type 2 diabetes who had inadequate glycemic control with metformin, we conducted a systematic review and meta-analysis. This was necessary to fill the gap and provide a comprehensive assessment of semaglutide compared to sitagliptin, a commonly prescribed DPP-4 inhibitor, in this patient population. METHODS: A comprehensive and systematic search was carried out on reputable databases including PubMed, the Cochrane Library, and Elsevier's ScienceDirect to identify relevant studies that compared the efficacy of once-weekly Semaglutide with once-daily Sitagliptin in individuals diagnosed with type 2 diabetes mellitus. The analysis of the gathered data was performed utilizing the random-effects model, which considers both within-study and between-study variations. RESULTS: The meta-analysis incorporated three randomized controlled trials (RCTs), encompassing 2401 participants, with a balanced distribution across the treatment groups. The primary focus of the study revolved around evaluating changes in HbA1C, blood pressure, pulse rate, body weight, waist circumference, and BMI. The findings revealed that once-weekly Semaglutide showed substantially improved HbA1C (WMD: -0.98; 95% CI: -1.28, -0.69, p-value: < 0.0001; I2: 100%), systolic (WMD: -3.73; 95% CI: -5.42, -2.04, p-value: <0.0001; I2: 100%) and diastolic blood pressures (WMD: -0.66; 95% CI: -1.02, -0.29, p-value: 0.0005; I2: 100%), and body weight (WMD: -3.17; 95% CI: -3.84, -2.49, p-value: <0.00001; I2: 100%) compared to once-daily Sitagliptin. However, there was an observed increase in pulse rate (WMD: 3.33; 95% CI: 1.61, 5.06, p-value: <0.00001; I2: 100%) associated with Semaglutide treatment. Regarding secondary outcomes, there was an elevated risk of total adverse events and premature treatment discontinuation with Semaglutide. The risk of serious, severe, moderate, and mild adverse events did not significantly differ between the two treatments. CONCLUSIONS: In conclusion, the administration of once-weekly Semaglutide exhibited a substantial reduction in HbA1c, average systolic blood pressure (SBP), mean diastolic blood pressure (DBP), body weight, waist circumference, body mass index (BMI), and a rise in pulse rate, as opposed to the once-daily administration of Sitagliptin.

Effects of Non-steroidal Anti-inflammatory Drugs (NSAIDs) and Gastroprotective NSAIDs on the Gastrointestinal Tract: A Narrative Review.

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used for their anti-inflammatory, antipyretic, and analgesic properties. However, their use is often associated with gastrointestinal tract (GIT) side effects due to the inhibition of both cyclooxygenase (COX)-1 and COX-2 enzymes, leading to a decrease in gastroprotective prostaglandins (PG). To minimize these adverse effects, various approaches have been explored, including selective COX-2 inhibitors, NO-NSAIDs (nitric oxide-releasing NSAIDs), and dual COX/LOX (lipoxygenase) NSAIDs. However, the effects of these gastroprotective NSAIDs on the GIT and their efficacy remains uncertain. This review aims to provide an overview of the current understanding of the effects of traditional NSAIDs and gastroprotective NSAIDs on GIT. We discuss the underlying mechanisms of GIT damage caused by NSAIDs, including mucosal injury, ulceration, and bleeding, and the potential of gastroprotective NSAIDs to mitigate these effects. We also summarize recent studies on the efficacy and safety of various gastroprotective NSAIDs and highlight the limitations and challenges of these approaches. The review concludes with recommendations for future research in this field.
