Heated tobacco products- well known or well understood? A national cross-sectional study on knowledge, attitudes and usage in Pakistan.

BACKGROUND: Heated tobacco products (HTPs) are reshaping the tobacco industry and just recently, a plan was sought to regularize HTPs in Pakistan. Pakistan provides an intriguing case study in this context, as tobacco use is deeply ingrained in public use. To ensure that future evidence-based policy recommendations are grounded in the public's knowledge, attitudes, and usage of HTPs, a nationwide survey must be conducted. METHODS: A cross-sectional study was conducted using an online-based questionnaire nationwide in Pakistan. The questionnaire was validated and distributed through convenience sampling. The questionnaire assessed participants' knowledge, attitudes, and usage of HTPs. Descriptive statistics was used to describe participants' response and linear regression was performed at a p-value of < 0.05 using SPSS version 26. RESULTS: In our sample of 1195 respondents (mean age of 33 years, 41.8% males and 58.2% females), 54.7% had previously heard about HTPs and 16.9% reported using HTPs at least once. Additionally, 38.24% were unsure of the legality of HTP use. Those with monthly household incomes of PKR 100,000 to 500,000, were more likely to have higher knowledge scores (OR:1.80[1.07-3.04]). On the other hand, males (OR:0.70 [0.55-0.89]) and respondents from Balochistan (OR:0.40 [0.22-0.71]) were more likely to have lower knowledge scores. The strongest motivators were the enjoyability of HTPs (55.73%) and usage as a cigarette alternative (54.64%), while the strongest deterrents were the negative health effects (82.68%) and potential for addiction (81.01%). CONCLUSION: Our study underscores the need for awareness campaigns and interventions concerning HTPs, given prevalent preconceived notions and mixed attitudes among respondents. It was found that women and households with higher incomes scored higher on knowledge. Subjective enjoyment and a substitute for cigarettes were important motivators, but the most mentioned deterrents were the possibility of addiction and the detrimental effects on health. These insights form the basis for informed policy making for non-cigarette tobacco products.

Neuroprotection strategies in traumatic brain injury: Studying the effectiveness of different clinical approaches.

Background: This review delves into clinical strategies aimed at addressing the complexities of traumatic brain injury (TBI), specifically focusing on pharmaceutical interventions and stem cell therapies as potential avenues for enhancing TBI outcomes. Methods: A thorough review of clinical strategies for TBI management, encompassing pharmaceutical and nonpharmaceutical interventions, was performed. PubMed, MEDLINE and clinical trial databases were searched to identify relevant studies and clinical trials. Inclusion criteria consisted of studies involving pharmaceutical agents and other clinical approaches (i.e., stem cell therapies) targeting neuroinflammation, excitotoxicity, oxidative stress, and neurodegeneration in TBI. Data from clinical trials and ongoing research initiatives were analyzed to assess the current status and potential of these clinical approaches. Results: Many trials have been conducted to face the challenge that is TBI. These interventions are designed to target critical aspects of secondary brain injury, encompassing neuroinflammation, excitotoxicity, oxidative stress, and neurodegeneration. Despite this, there is no panacea or definitive remedy for this condition. Combining therapies in a patient-tailored approach seems to be our best chance to improve these patients' outcomes, but systematic protocols are needed. Conclusion: Clinical strategies represent dynamic and continually evolving pathways in TBI management. This review provides an extensive overview of the existing landscape of clinical approaches and promising new studies and outlines their influence on patient outcomes. By highlighting challenges and presenting opportunities, it contributes to the ongoing mission to advance clinical care for individuals impacted by TBI.

Neuroprotection: Surgical approaches in traumatic brain injury.

Background: This review is centered on the pivotal role of surgical interventions within the comprehensive management of traumatic brain injury (TBI). Surgical strategies are indispensable components of TBI care, encompassing primary injury management and the alleviation of secondary injury processes, including the handling of intracranial hemorrhages (ICHs), contusions, and mass lesions. Methods: A systematic review was carried out by searching databases including PubMed, Embase, and Scopus. The inclusion criteria involved studies discussing surgical strategies for TBI, with a focus on primary injury management, ICHs, contusions, and mass lesions.

Gender Differences in Medical Students' Perception of Neurosurgery: A Cross-Sectional Study from Pakistan.

BACKGROUND: Despite 15,000 annual medical graduates, few choose neurosurgery, especially women. The scarcity of female neurosurgeons is a global concern, particularly in resource-limited settings such as Pakistan. This study focuses on gender-based differences in medical student perceptions of neurosurgery in Pakistan. METHODS: A nationwide cross-sectional study was conducted from March 6 to April 20, 2023, using a Web-based survey. Data collectors were recruited through an ambassadorship program, distributed evenly across all provinces. A questionnaire was used after a pilot study. Data analysis was performed using SPSS version 26 and STATA 15. RESULTS: A total of 2353 medical students participated in the study, of which 63.4% were female and 36.5% were male. Around 40.3% of women strongly agreed to the existence of potential gender bias in neurosurgery, in contrast to their corresponding male students, at 17.3%. Some of the highlighted deterring factors in pursuing neurosurgery as a career according to women include longer training duration (44.6%), poor work-life balance (41%), limited residency slots (50.6%), and limited exposure to neurosurgery (45.1%). Other factors included the high-intensity nature of training (33.6%), perceived gender bias (31.4%), competitive work environment (29.1%), complex surgical skills (38.6%), required level of medical knowledge (29.6%), and financial burden (33.9%). CONCLUSIONS: Our study shows that female students are more likely to believe in the existence of potential gender bias in the field compared with their counterpart male participants, which highlights the graveness of the situation in view of the evident paucity of female neurosurgeons in the country.
