Perception and practices regarding cannabis consumption in Karachi, Pakistan: A cross-sectional study.

Several studies have been carried out regarding the awareness and usage of cannabis around the world, especially in developed countries. Pakistan ranks amongst the top nations in regards to cannabis consumption. However, the amount of literature shedding light on people's perception, knowledge and practices are scarce. Therefore, the authors sought to establish a baseline study to ignite the discussion on the possibility of cannabis' induction in the medical field in Pakistan, and additionally provide a foundation for further research. The purpose of this study was to investigate the level of understanding and consumption practices in Karachi with respondents from different socio-economic backgrounds, age groups and gender regarding cannabis use and assessing the awareness of the general population. The null hypothesis is that the usage of cannabis does not have a significant correlation with age, gender, or socio-economic status of a population. We conducted a cross-sectional study in November 2018 using convenience sampling and interviewed 518 individuals for their gender, age, and socio-economic status, to determine their knowledge, attitudes, and practices regarding cannabis usage. The participants were questioned about their knowledge and its source. Attitudes were judged using three and five-point Likert scales while questions regarding practices centered upon the past and current usage of cannabis. One-way analysis of variance and chi-square tests were used as the primary statistical tests. Out of the 518 people who responded, more than half of the respondents were males (n = 340, 65.6%). The majority was familiar with the use of cannabis (n = 514, 99.2%), and the different ways in which it is consumed (n = 435, 84%). About one-third of the participants happened to consume cannabis (n = 168, 32.4%), and a quarter mentioned recreational use/curiosity as the principal reason (n = 134, 25.9%). Majority of the respondents agreed upon the harmful effects of consuming cannabis (n = 364, 70.3%), while when compared to other inimical drugs, half of them believed it to be less harmful (n = 259, 50%). Besides, an overwhelming majority stated, that if they were to consume cannabis, they would not consider taking permission from their parents/guardians (n = 441, 85.2%). Concerning legality, three-fifths of the participants chose cannabis to remain illegal in Pakistan (n = 307, 59.3%) and, for not consuming/quitting cannabis, the primary reason chosen was its harmful consequences (n = 210, 40.5%). Our study revealed that knowledge about usage of cannabis still requires a great deal of attention. Only individuals from higher socio-economic backgrounds have a positive attitude towards cannabis usage and are aware of it. There is an urgent need for awareness programs that especially reach out to the lower socio-economic status population, who otherwise do not have access to essential information resources. We also found that males were more likely to be consumers and to have more knowledge about cannabis, therefore, it is equally important to educate females about this topic so that an informed discussion about cannabis use and its medical benefits can be generated in Pakistan.

Restless Leg Syndrome in Patients with Liver Cirrhosis! Its Frequency, Severity, and Correlation.

BACKGROUND: Restless leg syndrome (RLS) has been recognized as a typical additional manifestation among patients with cirrhosis of the liver. RLS prevalence in liver cirrhosis further worsens the quality of life, which has already been compromised with the disease-related complications of cirrhosis itself. AIMS: The study aimed to determine the frequency and severity of Restless Leg Syndrome (RLS) among patients with cirrhosis of the liver and to correlate its severity with the severity of cirrhosis. METHODS: This prospective cross-sectional study was carried out at Ruth K.M. Pfau Civil Hospital (Karachi, Pakistan) from December 2019 to February 2020. Three hundred and fifteen cirrhotic patients with any etiology were included in the study after informed written consent. Restless leg syndrome with its severity was determined in all cirrhotic patients. For continuous variables, means and medians with standard deviations were calculated, while percentages and proportions were used for discrete variables. Spearman correlation was used to find significance between RLS Severity Score (RSS) and Model of End-stage Liver Disease MELD Score. A p value of < 0.05 was considered significant for all analyses. RESULTS: The frequency of RLS among cirrhotic patients was 38.4%. More than half (54.5%) of the patients had severe RLS. Viral related hepatitis C and hepatitis B were the most common cause of cirrhosis of the liver (57.8% and 30.8%). A significant difference was found between as patients both with or without RLS in terms of age (p=0.003), gender (p=0.005), hemoglobin (p=0.00), and serum albumin (p=0.01). No significant association was found between RLS severity score and MELD Score (p=0.693). CONCLUSION: Prevalence of RLS is very high among cirrhotic patients, but no correlation was found between the severity of RLS and cirrhosis. Further studies should be carried out to assess the quality of life in cirrhotic patients having RLS.

Prevalence and Predictors of the Use of Sunscreen Amongst Medical Students: A Multi-center Cross-sectional Study.

Objective Sun exposure is a primary preventable risk factor for skin cancer. Sunscreen has been shown to reduce the risk of certain skin cancers such as squamous cell carcinoma and melanoma. We aimed to assess the prevalence and predictors of sunscreen use among medical students in Karachi. Methods A multi-center cross-sectional study was conducted among 578 students from multiple medical universities in Karachi, Pakistan. The levels of use of sunscreen were recorded using a comprehensive questionnaire consisting of 29 questions. Descriptive statistics were used and p-values less than 0.05 calculated using the chi-square test were considered significant. Results A majority (n=441, 73.9%) of the participants in this study were female students. Sunscreen use was prevalent in 415 (69.5%) participants. Female students were more aware of the risk of skin cancer from extended sun exposure (n=186, 72.4%). Sunscreen use was significantly associated with gender (p<0.001) and the propensity to get sunburned easily (p=0.001). Few (n=19, 5.0%) students reported being well-versed regarding skin cancer and its risk factors. Most participants were aware of the use of sunscreen for sunburn prevention (n=473, 79.2%), though knowledge of the additional benefits of sunscreen, such as the prevention of skin cancer (n=257, 43.0%) and aging (n=199, 33.3%), was lacking. Conclusion There is an evident lack of knowledge of the importance of sunscreen protection among medical students, particularly regarding the prevention of skin cancer and skin aging. However, an overall positive attitude was observed regarding the use of sunscreen among female students. Medical students are an imperative part of our future healthcare system and should be adequately informed on sunscreen benefits and skin cancer prevention.

Knowledge and Attitude Towards Cardiopulmonary Resuscitation Among Doctors of a Tertiary Care Hospital in Karachi.

Objective Cardiac arrest is an emergency, which can be managed effectively by sound knowledge and practice of basic life support (BLS) skills. However, it has been globally reported that the knowledge of doctors regarding cardiopulmonary resuscitation (CPR) and BLS is sub-standard. We conducted this study with the aim to assess the knowledge and attitude of doctors toward CPR in Dr. Ruth K.M. Pfau Civil Hospital, one of the largest tertiary care hospitals, in Pakistan. Methods We conducted a cross-sectional study, in Dr. Ruth K.M. Pfau Civil Hospital located in Karachi, Pakistan, using cluster sampling. A total of 285 doctors were interviewed. Results A majority of the doctors were unaware of the revised rate and depth of chest compressions (65.6% and 75.8% respectively). While many know the abbreviations of BLS and CPR (96.55% and 95.4%, respectively), 56.5% did not know what automated external defibrillator (AED) stood for. CPR was preferred over chest compression-only resuscitation (CCR) by 91.6% of the doctors. Half of the participants rated their knowledge as average. Most stated that they will not be reluctant to perform CPR in an emergency situation. The majority also agreed that BLS training should be an integral part of the medical curriculum. Conclusion There is an evident lack of knowledge of CPR among healthcare professionals, particularly regarding the updates made in the 2015 American Heart Association (AHA) guidelines. However, an overall positive attitude was observed.
