This study investigates the health implications of sharing a shisha (hookah) mouthpiece during smoking, with a focus on tuberculosis (TB) and hepatitis prevalence in Sub Saharan Africa. It examines shisha smoking behavior patterns and associated risks of disease transmission among those sharing a common mouthpiece. Through literature review and empirical data analysis, the research highlights epidemiological factors driving TB and hepatitis transmission within the context of shisha smoking in Sub Saharan Africa. Exploring cultural, social, and behavioral determinants influencing shisha mouthpiece sharing, the study offers insights into interventions and public health strategies. It emphasizes the need for targeted health education campaigns, policy interventions, and community-based initiatives to promote safer smoking practices. Immediate coordinated public health interventions, including educational campaigns and regulatory measures, are recommended. Collaboration among healthcare professionals, policymakers, and communities is essential. These insights deepen the understanding of challenges posed by communal shisha smoking in Sub Saharan Africa, laying the groundwork for evidence-based interventions to reduce TB and hepatitis transmission and enhance overall health outcomes in the region. This research underscores the urgency of addressing the risks associated with shisha smoking, aiming to mitigate disease transmission and improve population health in Sub Saharan Africa. 展开更多

Background: Health care workers are respected in every society and have a strong influence on the behaviour of the community. In order to reduce the shisha dependence in the Pakistani population, it is necessary to evaluate the perspective of future doctors and pharmacists regarding this addiction as they become role models for the future generations. Objective: The aim is to compare the knowledge, attitudes, and practices of shisha use among medical students and pharmacy students in order to assess their support in the anti-shisha campaigns of Pakistan. Methodology: Cross sectional study was performed in four major medical universities of Karachi, Pakistan through a modification of the WHO global health survey questionnaire. Result: 398 medical students and 470 pharmacy students were included in the study which showed that currently 9.6% pharmacy students and 4.8% medical students used shisha daily (p = 0.000). Pharmacy students started shisha use in less than 15 years of age while this number was 29.5% among medical students (P = 0.000). Moreover, 44.6% pharmacy students and 50% medical students were not planning to quit this addiction within the next six months. 14% of pharmacy students and 20.4% in medical students (P = 0.002) were unaware that passive smoking caused lung cancer, while 23.4% pharmacy students and 33.5% medical students rejected it as cause of heart diseases (p = 0.006). Conclusion: A significant number of medical and pharmacy students were unaware about some of the serious consequences of shisha smoking. Therefore, both groups of students need to be educated about the health hazards of shisha use, in order to control this growing menace. 展开更多

60年前的1964年5月2日,中国登山队10名登山队员成功登顶海拔8027m的希夏邦马峰。作为全球8000m以高的最高峰之一,希夏邦马也是一座完全位于我国境内的山峰。在这次登山过程中,中国科学院组织了希夏邦马峰科学考察,其在地质学方面取得的... 60年前的1964年5月2日,中国登山队10名登山队员成功登顶海拔8027m的希夏邦马峰。作为全球8000m以高的最高峰之一,希夏邦马也是一座完全位于我国境内的山峰。在这次登山过程中,中国科学院组织了希夏邦马峰科学考察,其在地质学方面取得的主要学术成果包括:(1)将区域上变质的岩石归类为希夏邦马群,并将其划分为下部的片麻岩(包括下段粗粒的片麻岩和上段细粒的变粒岩)和上部的片岩两类,相当于现今划分的高喜马拉雅结晶岩系和肉切村群浅变质岩系。同时认为,希夏邦马峰顶的岩石为上述片麻岩;(2)建立了区内显生宙地层系统,分别为上古生界港门穹群、中生界土隆群和雪拉群及新生界野博康加勒群;(3)在5800m营地附近的野博康加勒群下部砂砾岩中发现了高山栎植物化石,并据此提出了喜马拉雅山3Ma以来隆升了约3000m的认识;(4)运用K-Ar法获得的区内淡色花岗岩-伟晶岩的年龄为13~15Ma,而眼球状片麻岩的年龄为19~35Ma,表明希夏邦马形成于非常年轻的中新世。希夏邦马考察及取得的成果对后来我国喜马拉雅山其他地区的考察起到了很好的示范作用。但是,1964年登顶以后,很少再有地质学家对此山峰展开进一步的科学考察与研究。近30年来,珠穆朗玛峰及喜马拉雅地区其他山峰的研究已经基本明确,喜马拉雅由下部的高喜马拉雅深变质岩系和上部未变质的特提斯喜马拉雅沉积岩系构成,两者之间为遭受韧性伸展变形的构造岩系,即藏南拆离系。未来,应着重检查希夏邦马地区变质岩岩石性质、显生宙地层层序及区域构造特征,确定峰顶究竟是变质岩还是淡色花岗岩,并进一步研究含高山栎化石地层的时代及沉积物形成机制等。 展开更多

The use of tobacco products constitutes the leading cause of preventable deaths in the world. In Egypt, data on the national prevalence of cigarette and waterpipe smoking are lacking, yet such data are vital to tobacco control efforts. We designed and implemented a sampling method to generate population-based prevalence estimates for tobacco smoking in Egypt. In 2005, a total of 3369 adults ages 18 and above, including 1867 females and 1502 males, participated in the survey. Among males, the national prevalence of former cigarette smoking was 18.1%, and 27.5% reported current smoking. Exclusive current waterpipe smoking was reported by 7.2% of adult males, and a further 3.4% reported smoking both waterpipes and cigarettes. Tobacco smoking was rarely reported by females;among them the national prevalence of current cigarette smoking was 0.3%. This study produced the first robust estimate of the national prevalence of cigarette and waterpipe smoking in Egypt based on a rigorous probability sample. Along with the more recent Global Adult Tobacco Survey, carried out by the World Health Organization in 2009, the results will be useful in assessing smoking trends in Egypt and in evaluating the impacts of recent tobacco control laws. 展开更多
