Assessment of COVID-19 related preventive measures in medical students across a lower-middle-income country: A cross-sectional study from Pakistan.

Objectives: This study aims to identify the effect of having COVID-19 positive close contact on practices and evaluate practices regarding COVID-19 prevention among medical students and the differences among clinical and preclinical students. Study design: The cross-sectional study included medical students from the Micro-fest++ event held on 30th May 2020. Methods: Participants filled a questionnaire of 15 questions regarding COVID preventive measures practices having satisfactory reliability (Cronbach's alpha = 0.715) and validity. The Statistical Package for Social Sciences (IBM SPSS) 26.0 was used for data analysis. Out of 1342 medical students, the majority were female (N = 881, 65.6%). Greater proportion (47%) of students had good practices (>85.7%) (p < 0.05). Results: Having COVID-19 positive relatives resulted in higher positive responses for practices with 11.86 ± 1.94 (out of 14) compared to 11.78 ± 2.38 for the COVID-19 negative group. Clinical year students compared to preclinical students responded positively to all questions, except one, and had a better score of 11.90 ± 2.28 (out of 14) compared to 11.61 ± 2.37 (p < 0.05). A significant difference was noted for "Information on preventive measures" (p < 0.01), "Avoiding crowds and staying home" (p < 0.05), "Social distancing (maintain 3 feet)" (p < 0.01), and "Practices of disinfection after going outside" (p < 0.05). Conclusions: Overall, medical students showed good practices, but a lack of knowledge in certain areas requires addressing infection during clinical rotations. A greater proportion of clinical students and those having a COVID-19 positive relative showed better adherence to practices.

Anthropogenic Effects of Coal Mining on Ecological Resources of the Central Indus Basin, Pakistan.

Water is essential for life, agriculture, and industrialization; however, a rapid increase in population is constantly causing water scarcity and pollution in Pakistan. Mining activities produce the potential toxic element (PTE) accumulation, which lead to unnatural enrichment, ecological pollution, and environmental degradation. The ecological resources impeded by the PTEs cause serious abnormalities in the population through dermal contact, inhalation, and digestion. Mining induced anthropogenic activities are well-known causes of contamination of ecological resources. The produced effluents have drastic effects by changing the physical, chemical, and biological properties of the concerned resources. The Central Indus Basin is a well-known coal regime, where more than 160 mines are active at present. The samples that were collected from the mine water, groundwater, surface water, and the soil were analyzed by atomic absorption and elemental determination analysis (EDA) for an assessment of their quality and the presence of PTEs. The results were correlated with available quality standards, including the World Health Organization (WHO), National Standard of Drinking Water Quality (NSDWQ), World Wildlife Fund (WWF), and Sediment Quality Guidelines (SQGs). These analyses showed the noticeable anthropogenic concentration of PTEs, like iron, cadmium, sulphur, and copper, which can degrade the quality of resources in the Central Indus Basin and have adverse effects on human health. An excessive amount of acid mine drainage (AMD) draws attention to some suitable active or passive treatments for disposal from mines to avoid degradation of ecological resources in the Central Indus Basin of Pakistan.

Prevalence of hydatidosis in livestocks in Chakwal District of Pakistan

Background:Hydatidosis is a zoonotic parasitic disease and a serious human and animal health problem in many endemic areas of the world. It is caused by the tapeworm parasite of Echinococcus granulosus sensu lato. This parasite is endemic in the neighboring countries like China, Iran and India. There are limited studies on CE in Pakistan.Methods:This study primarily aimed to determine the prevalence of hydatidosis in slaughtered livestocks in Chakwal district (Chakwal, Bhaun, Kallar kahar, Choa saidan shah and Balkasar) from June to December 2015. The livestocks were inspected after slaughtering and the ages, breeds and organ wise prevalence were recorded.Results:A total of 6 095 animals (sheep, goat, buffaloes and cattle) of different genders, ages and breeds were inspected after slaughtering. Overall prevalence was 8.55% (88/1 045) in sheep followed by 8.42% (88/1 045), 6.90% (4/58), 2.99% (138/4 608) in cattle, buffaloes and goats, respectively. Liver wise prevalence was 7.75%, 6.90%, 0.06%, 1.30% in cattle, buffaloes, goats and sheep, respectively while lung wise prevalence was 7.55%, 0.67%, 0.00%, 0.00%, in sheep, cattle, buffaloes and goats, respectively. Male (9.50%) were more infected than female (1.96%) in all hosts. Breed wise prevalence was higher in desi breed of cattle followed by crossbreed and other breeds. In goats, teddhi breed was more infected then beetal while in sheep Afghani breed was more infected than the others. Cattle of 6-9 years groups were more infected than 0-3 and 3-6 years age groups. Buffaloes of the only age group of 6-9 years were infected while in goat and sheep 3-6 years were more infected than 0-3 years. According to the statistical analysis there was a significant difference (P<0.05) in prevalence of hydatidosis when ages, genders and organs were compared.Conclusion:The hydatidosis is a serious parasitic problem in the study area for livestocks. The disease should be monitored on regular basis in other areas of Pakistan and future studies should be carried out to explore the real prevalence in Pakistan.
