Preliminary findings of a study on the practice of self-medication of antibiotics among the practicing nurses of a tertiary care hospital

Objectives: Antibiotic resistance is indeed a global concern. It is of significant concern especially in the low-middle income countries because of the ease of accessibility, affordability, and absence of regulations pertaining to the dispensing of non-prescription antibiotics. This study aims to estimate the frequency and factors associated with the self-medication of antibiotics found among the practicing nurses.Methods: We conducted a descriptive cross-sectional study at a tertiary care hospital in Karachi, Pakistan from July 2016 to August 2016.Results: Of the 48 recruited nurses, 60.4% (29/48) were practicing self-medication of antibiotics. There were slightly more male nurses (17/29) than their female counterparts. The most frequently used antibiotic was Amoxicillin/Clavulanic acid, which was reported by 72.4% (21/29) of the nurses. The most prominent factor urging the nurses for practicing self-medication of antibiotics was their perceived knowledge of antibiotics, as was the case with 72.4% (21/29) of the nurses. Fever (79.3%) and sore throat (65.5%) were the two most frequent health problems that prompted the nurses to practice antibiotics self-medication. An earlier experience of the use of antibiotics was reported by 51.7% (15/29) of the nurses. Only 20.7% (6/29) of the nurses completed the entire antibiotic course. The adverse effects of antibiotics were encountered by 41.4% (12/29) of the nurses, which included diarrhoea, nausea, and vomiting.Conclusions: The self-medication of antibiotics is a frequent practice found among the practicing nurses in Karachi. It is a pressing concern and needs considerable attention from the healthcare authorities

Structure of Parabolic Trough Collector Model for Local Heating and Air Conditioning

Concentrating solar power (CSP) is a type of solar energy that uses mirrors (concentrators) to concentrate sunlight from a large area to a small area where it is absorbed and converted to heat at high temperatures. CSP plants have a big advantage over photovoltaic (PV) power plants because they can use conventional fuels and store thermal energy to make up for the fact that solar energy doesn’t always work. In this paper, a parabolic trough collector (PTC) with the following parameters was designed to investigate the efficiency of a small-scale PTC to heat a synthetic heat transfer fluid that may be used for domestic heating or cooling. PTC 2 m in length, 30 cm rim radius

Impact of IL28B genetic variant's and viral genotype on treatment outcome of hepatitis C infected patients

Introduction: Viral genotype and variation in host genes involved in the immune response may predict the treatment response in patients infected with HCV. The present study was designed to determine the distribution pattern of HCV and host genotypes in Chronic Hepatitis C (CHC) patients and their association with virological response and other risk factors. Methodology: Two hundred and fifty (n = 250) HCV positive patients were included in the study. HCV and Interleukin 28B (IL28B) genotyping was carried out by PCR-RFLP. Results: Viral genotype 3 was the predominant genotype seen in 187 (74.8%) patients. Wild genotype predominated in rs12979860, rs12980275 and rs8099917 SNP of IL28B gene. A significant difference was found in end stage virological response (EVR) between HCV genotype 1 infected patients with wild and variant genotype for rs12980275 and rs8099917 SNPs respectively (P < 0.05). On multivariate analysis all the SNPs were found to be associated with each other (P < 0.05) with rs12980275 SNP associated with history of Jaundice (P < 0.05). Viral genotype 3 was significantly associated with age (< 50 years) and rapid virological response (RVR) while as viral genotype 1 was significantly associated with history of surgery on multivariate analysis (P < 0.05). Conclusions: The viral genotype and IL28B polymorphisms are important factors to personalize antiviral therapy of patients with CHC

Socio-economic advantages and climate adaptation in sustainable vs. conventional cotton: evidence from Pakistan

Two groups of cotton growers participated in this study; the first, referred as “conventional cotton producers” (CCPs), continues to use traditional techniques. The second group, known as sustainable cotton producers (SCPs), adheres to practices that are socially acceptable, economically feasible, and environment friendly. This study was designed to undertake a thorough socio-economic analysis of CCP and SCP in terms of cost of production, yield, and adaptations for climate change. The data were collected from a total of 275 farming households (138 SCPs and 137 CCPs) from two districts, namely, Bahawalpur and Rajanpur, Punjab, Pakistan. The data were analyzed using the benefit–cost ratio (BCR), paired sampled t-test, and log–log regression model in SPSS. The results of the study revealed that the cost of production for SCP was significantly less than CCP and the value of BCR for SCP is higher than CCP. The results of the study also revealed that the land preparation costs, irrigation costs, and fertilizer and pesticide costs decrease the cotton yield of CCP, while land area owned and picking costs showed no significant influence on the yield of CCP. On the other hand, all cost items except fertilizer cost have a positive impact on CCP’s cotton yield. The results also indicated that SCP farmers adopted more of adaptation practices for climate change than CCP. This study concluded that SCP has significant advantages over CCP. Therefore, it is recommended that the government should prioritize incentives for SCP adoption to enhance yield and environmental sustainability in cotton farming

Prevalence of Mistreatment or Belittlement among Medical Students – A Cross Sectional Survey at a Private Medical School in Karachi, Pakistan

Background: Mistreatment or belittlement of medical students either by faculty or fellow students has often been reported. Perception of mistreatment has also been associated with increased degree of psychological morbidity. There is a lack of such studies being conducted amongst the medical students of Pakistan. The aim of this study was to determine the prevalence and forms of perceived mistreatment and presence of mental health morbidity in a private medical school in Pakistan. Also, any association between mental health morbidity and mistreatment was to be identified. Methods: A cross sectional study was carried out on medical students from Aga Khan University Hospital, Karachi, Pakistan during the period of June-September 2007. A self administered questionnaire, adapted from Frank et al and Baldwin et al was distributed to a total of 350 students. The questionnaire consisted of three parts: the first dealing with the demographics of the population, the second concerning the various forms of mistreatment, while the third assessed the mental health of students using the General Health Questionnaire 12(GHQ12). Descriptive statistics were performed. The Chi-square test and Fisher\u27s exact tests were applied. Results: A total of 350 students were approached out of which 232 completed the questionnaire giving a response rate of 66.2%. Mistreatment was reported by 62.5% (145/232) of the respondents. Of these, 69.7% (83/145) were males and 54.9% (62/145) were females. There was a significant relationship between gender, year division, stress at medical school and possible use of drugs/alcohol and reported mistreatment but no statistical relationship was seen with psychiatric morbidity. The overall prevalence of psychological morbidity was 34.8% (77/221). Conclusion: This study suggests high prevalence of perceived mistreatment and psychological morbidity among Pakistani medical students. However, no association was found between these two aspects of medical student education. There is a need to bring about changes to make the medical education environment conducive to learning. Increased student feedback, support systems and guidance about progress throughout the year and the provision of adequate learning resources may provide help with resolving both of these issues
