A Clinical Audit of blood component transfusion practices in Paediatric intensive care unit of a Tertiary Care Hospital, Rawalpindi

Background: To audit the practices involved in blood component transfusion in the management of patients in paediatric intensive care unit of our hospital and to determine the appropriateness of transfusion after comparing them with clinical practice guidelines recommended by Royal Children Hospital (RCH). Methods: All patients admitted in pediatric intensive care which were managed with blood component transfusions were retrospectively audited for 8 weeks. Management details including indications of transfusion and its appropriateness were recorded. Clinical practice guidelines recommended by Royal Children Hospital (RCH) were used as standards. Results: One hundred and ninety-two transfusions were done during the study period out of which 58 percent were done to males and 41 percent to females. Majority of transfusions were done in infants (44%) and O Positive blood group was found rampant among blood groups of all recipients (33.3%). Red cell concentrates were predominantly (55.7%) and appropriately (72%) transfusion among all blood components. Platelet concentrates were most inappropriately transfused (57%) followed by fresh frozen plasma (54%) and red cell concentrates (27%). There was significant percentage of inappropriate transfusion of all blood components (p=0.00). Conclusion: All blood components were significantly found inappropriately transfused, commonest component being platelet concentrates

A comparative analysis of multiple sequence alignments for biological data

Multiple sequence alignment plays a key role in the computational analysis of biological data. Different programs are developed to analyze the sequence similarity. This paper highlights the algorithmic techniques of the most popular multiple sequence alignment programs. These programs are then evaluated on the basis of execution time and scalability. The overall performance of these programs is assessed to highlight their strengths and weaknesses with reference to their algorithmic techniques. In terms of overall alignment quality, T-Coffee and Mafft attain the highest average scores, whereas K-align has the minimum computation time

Non-ionic iodinated contrast-induced sialadenitis with parotid gland sparing in patient of hepatocellular carcinoma

61-years-old male patient presented with complain of neck swelling and soreness following contrast-enhanced (CE) CT examination with resolution of symptoms in 36-48 hours. He is diagnosed with hepatitis C virus and hepatocellular carcinoma (HCC); already treated with radiofrequency ablation for HCC. He had already undergone two CECT examinations before he was referred to our institution for disease staging/treatment. He also underwent three triphasic CT scan examinations at our institution during the course of treatment for treatment response and staging. Patient remained undiagnosed up to his fourth CT scan due to inability to relate symptoms with contrast administration. The patient was offered close monitoring on fifth CT exam and ultrasound of neck revealed enlarged and echogenic bilateral submandibular glands, however, thyroid and bilateral parotid glands appear unremarkable. This represents transient iodinated contrast induced sialadenitis with sparing of parotid glands

Determinants of overall knowledge of and attitudes towards HIV/AIDS transmission among ever-married women in Pakistan: evidence from the Demographic and Health Survey 2012–13

Iqbal S, Maqsood S, Zafar A, Zakar R, Zakria Zakar M, Fischer F. Determinants of overall knowledge of and attitudes towards HIV/AIDS transmission among ever-married women in Pakistan: evidence from the Demographic and Health Survey 2012–13. BMC Public Health. 2019;19(1): 793.Background HIV/AIDS has emerged as a serious public health issue across the globe, and particularly in developing countries. Comprehensive knowledge and positive attitudes are cornerstones for the prevention, control and treatment of HIV/AIDS. However, there are various misconceptions associated with HIV/AIDS transmission, which lead to negative attitudes towards people living with AIDS. The present study aims to explore the effects of these determinants, related to socio-demographic characteristics and autonomy, on women’s overall knowledge and attitudes regarding HIV/AIDS in Pakistan. Methods Secondary data analysis was carried out using the national representative dataset of the 2012–13 Pakistan Demographic and Health Survey. A series of questions related to HIV/AIDS was asked of 13,558 ever-married women aged 15–49 years to assess respondents’ knowledge regarding modes of HIV/AIDS transmission and preventative measures, as well as their attitudes towards people living with HIV/AIDS. Descriptive and bivariate statistics were used to identify associations with socio-demographic and autonomy-related variables. Furthermore, bivariate and multivariate logistic regression analyses were performed to assess the association between multiple factors and overall HIV/AIDS knowledge as well as attitudes towards people living with AIDS. Results The results show that only 42% of Pakistani women have heard about HIV/AIDS. Amongst these women, the majority (68%) have good overall knowledge of HIV/AIDS and more than 55% have positive attitudes towards people living with AIDS. Furthermore, women residing in urban areas, having at least secondary-level education, with high autonomy, belonging to the richest wealth quintile and having exposure to mass media had high overall knowledge and positive attitudes towards people living with AIDS. Conclusion The findings of this research support the relevance of women’s autonomy, education and exposure to mass media, particularly in rural areas of Pakistan, to address the lack of knowledge and eliminate various myths and stigmatisation of people living with HIV/AIDS. Furthermore, it reveals a need to increase focused and targeted interventions to enhance women’s knowledge and positive attitudes towards people living with HIV/AIDS. In this regard, the media can play a proactive role to gauge wider audience in creating awareness and eradicating the myths and misconceptions regarding HIV/AIDS

Polymorphism of the renalase gene in gestational diabetes mellitus

Renalase is considered as a novel candidate gene for type 2 diabetes. In this study, we aimed to investigate the relationship of serum renalase and two single nucleotide polymorphisms with gestational diabetes mellitus. One hundred and ninety-eight normotensive pregnant females (n=99 gestational diabetes mellitus; n=99 euglycemic pregnant controls) were classified according to the International Association of the Diabetes and Pregnancy Study criteria. Fasting and 2-h post glucose load blood levels and anthropometric assessment was performed. Serum renalase was measured using enzyme-linked immunosorbent assay, whereas DNA samples were genotyped for renalase single nucleotide polymorphisms rs2576178 and rs10887800 using Polymerase chain reaction-Restriction fragment length polymorphism method. In an age-matched case control study, no difference was observed in the serum levels of renalase (p\u3e0.05). The variant rs10887800 showed an association with gestational diabetes mellitus and remained significant after multiple adjustments (p\u3c0.05), whereas rs2576178 showed weak association (p=0.030) that was lost after multiple adjustments (p=0.09). We inferred a modest association of the rs10887800 polymorphism with gestational diabetes. Although gestational diabetes mellitus is self-reversible, yet presence of this minor G allele might predispose to metabolic syndrome phenotypes in near the future
