When surgeons are rarer than resources - our experience with improving access to thoracic surgery in an urban setting: A special report

With progressive globalisation enabled by technology, there is an increased interest in finding viable solutions to the myriad health problems faced by developing countries. In countries like Pakistan, occasionally the challenge is not a dearth of material resources but rather unavailability of expertise. The current paper was planned to share a model that was successfully implemented in the urban setting of Karachi, Pakistan, from 2012 onwards which significantly improved access to thoracic surgery for underprivileged individuals. Our model focussed on a qualified thoracic surgeon reviving a defunct thoracic surgical unit thereby optimising the use of resources already available in the community. The key to efficient outcomes was direct managerial control by the surgeon who first educated himself in the various processes involved. The model, with its challenges and solutions, has good potential for adaptation in other urban settings in the developing worl

Impact of today\u27s media on university student\u27s body image in Pakistan: a conservative, developing country\u27s perspective

Background: Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive. Methods: A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan\u27s largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated. Results: Of the 784 final respondents, 376 (48%) were males and 408 (52%) females. The mean age of males was 20.77 (+/-1.85) years and females was 20.38 (+/-1.63) years. Out of these, 358 (45.6%) respondents had a positive BID (body image dissatisfaction) score while 426 (54.4%) had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7%) were male and 265 (65.0%) were female. Of the respondents with a negative BID score, 283 (75.3%) were male and 143 (35.0%) were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p \u3c 0.0001) showing a statistically significant association between high media exposure and negative body image dissatisfaction. Finally, we looked at the association between gender and image dissatisfaction. Again a statistically significant association was found between positive body image dissatisfaction and female gender and negative body image dissatisfaction and male gender (p \u3c 0.0001). Conclusions: Our study confirmed the tendency of the media to have an overall negative effect on individuals\u27 body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in males as compared to females. Likewise, positive BID scores were more prevalent amongst females

Impact of interventions to prevent and manage preeclampsia and eclampsia on stillbirths

<p>Abstract</p> <p>Background</p> <p>Pre-eclampsia and Eclampsia are relatively common complications of pregnancy, leading to considerable maternal and fetal mortality and morbidity. We sought to review the effect of aspirin, calcium supplementation, antihypertensive agents and magnesium sulphate on risk stillbirths.</p> <p>Methods</p> <p>A systematic literature search was conducted to identify studies evaluating the above interventions. We used a standardized abstraction and grading format and performed meta-analyses where data were available from more than one studies. The estimated effect on stillbirths was determined by applying the standard Child Health Epidemiology Reference Group (CHERG) rules for multiple outcomes. For interventions with insufficient evidence for overall effect, a Delphi process was undertaken to estimate effectiveness.</p> <p>Results</p> <p>We identified 82 relevant studies. For aspirin, maganesium sulphate and use of antihypertensive we found an insignificant decrease in stillbirth and perinatal mortality. For calcium supplementation, there was a borderline significant reduction in stillbirths (RR 0.81, 95 % CI 0.63-1.03). We undertook a Delphi consultation among experts to assess the potential impact of a package of interventions for the management of pre-eclampsia and eclampsia (antihypertensive, magnesium sulphate and C-section if needed). The Delphi process suggested 20% reduction each in both antepartum and intrapartum stillbirths with the use of this package.</p> <p>Conclusions</p> <p>Despite promising benefits of calcium supplementation and aspirin use cases on maternal morbidity and eclampsia in high risk cases, further work is needed to ascertain their benefits in relation to stillbirths. The Delphi process undertaken for assessing potential impact of a package of interventions indicated that this could be associated with 20% reduction in stillbirths, for input into LiST.</p

Exploring the cAMP/PKA pathway in the corn smut pathogen Ustilago maydis through serial analysis of gene expression

Ustilago maydis is the causative agent of corn smut disease. The ability of the fungus to switch from budding to filamentous growth is required for pathogenesis. Mating type genes and signaling pathways (cAMP and MAPK) regulate morphogenesis and pathogenesis in U. maydis. A novel protein Hgll appears to be a downstream component of the cAMP pathway that influences cell morphology and sporulation during infection. The focus of this work was to further explore the role of the hgll gene in U. maydis through the construction of Serial Analysis of Gene Expression (SAGE) libraries to compare the transcriptomes of wild type and hgll mutant strains. The SAGE approach provides a quantitative gene expression profile and identifies differentially expressed genes. A key result of the SAGE work was the identification of a number of differentially expressed genes for putative zinc finger proteins in the transcriptome. A hypothetical protein encoded by the cthl (Cystine 3-histidine) gene had similarity to a zinc finger protein. This gene was disrupted to investigate its role in the morphology of U. maydis and in disease progression. Phenotypic characterization of the cthl mutant lead to the conclusion that the gene is required for normal morphology and completion of the life cycle in U. maydis, and that it might also be involved in the regulation of cell division. Overall, this work makes a contribution to our understanding of the cAMP signaling pathway in U. maydis and provides a wealth of expression data for future analysis.Land and Food Systems, Faculty ofGraduat

Risk factors predisposing to congenital heart defects

Introduction: Congenital heart disease (CHD) is associated with multiple risk factors, consanguinity may be one such significant factor. The role of consanguinity in the etiology of CHD is supported by inbreeding studies, which demonstrate an autosomal recessive pattern of inheritance of some congenital heart defects. This study was done to find out the risk factors for CHD. Methods: A case-control study was done on pediatric Patients at a tertiary care hospital, Aga Khan University Hospital, located in Karachi, Pakistan. A total of 500 Patients, 250 cases and 250 controls were included in the study. Results: Amongst the 250 cases (i.e. those diagnosed with CHD), 122 Patients (48.8%) were born of consanguineous marriages while in the controls (i.e. non-CHD) only 72 Patients (28.9%) showed a consanguinity amongst parents. On multivariate analysis, consanguinity emerged as an independent risk factor for CHD, adjusted odds ratio 2.59 (95% C. I. 1.73 - 3.87). Other risk factors included low birth weight, maternal co-morbidities, family history of CHD and first born child. On the other hand, medications used by the mother during the index pregnancy, maternal age and gender of the child did not significantly increase the risk of developing CHD. Conclusions: Analyses of our results show that parental consanguinity, family history of CHD, maternal co-morbidities, first born child and low birth weight are independent risk factors for CHD

Reducing transfusion-associated malaria in Pakistan: an algorithmic approach

Blood transfusions represent a small but significant source of malaria transmission. Most blood banks rely solely on donor questioning to exclude malaria patients from donating blood. No guidelines exist for in vitro screening of donor blood for malaria in endemic areas. Possible laboratory screening techniques include: microscopy; enzyme-linked immunosorbent assay (ELISA) antibody testing; polymerase chain reaction (PCR) testing; and rapid diagnostic antigen tests. However, all these modalities have diagnostic limitations. Based on a best evidence review, we present recommendations using an algorithmic approach to blood screening for malaria in Pakistan. This algorithm considers regional endemicity for malaria, as well as a detailed donor history, in order to decide whether donor blood should be tested with rapid antigen testing. We hope this algorithm will assist in the development of future national guidelines for screening blood for malaria that will reduce the risk of blood-borne transmission

Synthesis, characterization and docking studies of amide ligands as anti-leishmanial agents

Aim of this study was to synthesize new inhibitors on the basis of active site of aspartic protease enzyme and to evaluate their intended biological activity. A3D model of an enzyme was generated via homology modeling and series of novel amide ligands were synthesized by using a short high yield process, subsequently, analyzed in-silico and in-vitro anti-leishmanial activities. Characterization and identification was accomplished via NMR (H1& C13), infrared and mass spectroscopic techniques. Among all compound (4) was found to show significant activity (IC50 58±0.01) against Leishmania major (L. major) species. Furthermore, docking studies confirmed the inhibition of a targeted enzyme that supported the interaction of potent compound (4) with key residues (aspartic protease) via hydrogen bonds. Present study conferred about novel compound (4) as a promising compound to antagonize L. major activities in future
