Value of dedicated research time for IMGs in obtaining surgical residency training positions: A 10-year review of applicants from a medical college in Pakistan

Objective: International Medical Graduates (IMGs) secured greater than 10% of all general surgery (GS) residency positions in the US during the past decade. The Match process remains competitive, with a significant number of IMGs performing dedicated research before residency application. The impact of such research remains largely unknown. We aimed to provide an objective analysis of the impact of dedicated research time on obtaining a categorical GS residency position. Design: Data for National Resident Matching Program Match results from 2008-2017 was compiled from annual Match lists of the Aga Khan University, Medical College (Karachi, Pakistan). Medical graduates provided this information voluntarily each year. Data was exported to Microsoft Excel and used for descriptive and statistical analysis using SPSS. Candidates were divided into quasi-experimental groups based on their preference for direct application (no-research group, n = 64) or research prior to Match (research group, n = 20).Result: A total of 84 IMG applicants matched into GS residency positions in the US within the past decade. Amongst these, 18 matched directly into categorical positions while 66 applicants secured preliminary spots. A total of 37 (56%) preliminary candidates eventually secured categorical GS residency positions. Research group applicants had an overall 85% (n = 17) success rate of obtaining a categorical position, while no-research group had a 59% (n = 39) success rate (chi-square test, p = 0.04). Success rate was 69% (n = 38) for male applicants and 57% (n = 17) for female applicants. Median time to a categorical position was 4 years (2-6) for the research group and 3 years (1-6) for the no-research group.Conclusions: Our quasi-experimental study demonstrated a higher success rate for Aga Khan University, Medical College applicants with significant research background in the US, compared to those who did not. Better social integration, enhanced mentorship available during research, overcoming of cultural and linguistic barriers and a perception as better qualified candidate can be some factors contributing to higher success rates

A comparison of three diagnostic platforms for the detection of influenza A and B in children

Background: Viral flu is the predominant cause of hospitalization in young children, which invariably leads to enhanced morbidity and mortality in children in developing countries. Initial treatment of viral flu is based on presumptive diagnosis. Bedside testing is not common in clinical settings because of variable sensitivity and specificity of rapid tests in different settings. Methods: To address this issue, we evaluated the performance of Binax influenza A/B rapid testing kit against two robust molecular platforms (quantitative real-time polymerase chain reaction [qRT-PCR] and TaqMan array card [TAC]) in 24 nasopharyngeal (NP) swabs, collected from children under 5 years of age. Results: Binax was found to be less sensitive (56%), but 100% specific compared to qRT-PCR (100%) and TAC (>100%). Using TAC cards, 75% of samples were found to be coinfected with other bacterial and viral targets. Conclusion: Binax flu is suitable for bedside testing in clinical and community settings. The negative results of Binax should be interpreted with caution and confirmed by rapid molecular tests

Risk of appendicitis in patients with incidentally discovered appendicoliths

Background: An appendicolith-related appendiceal obstruction leading to appendicitis is a commonly encountered surgical emergency that has clear evidence-based management plans. However, there is no consensus on management of asymptomatic patients when appendicoliths are found incidentally. The objective of this study was to determine the risk of appendicitis in patients with an incidental finding of the appendicolith.Methods: A retrospective matched cohort study of patients with appendicolith discovered incidentally on computed tomographic scan from January 2008 to December 2014 at our institution was completed. The size and position of the appendicolith were ascertained. The study group was matched by age and gender to a control group. Both groups were contacted and interviewed regarding development of appendicitis.Results: In total, 111 patients with appendicolith were successfully contacted and included in the study. Mean age was found to be 38±15y with 36 (32%) of the study population being females. Mean length of appendix was 66±16mm, and mean width was 5.8±0.9mm. Mean size of the appendicolith was 3.6±1.1mm (1.4-7.8mm). Fifty-eight percent of appendicoliths was located at the proximal end or whole of appendix, 31% at mid area, and 11% at the distal end of appendix. All patients of the study and control groups were contacted, and at a mean follow-up of 4.0±1.7y, there was no occurrence of acute appendicitis in either group.CONCLUSIONS: Patients with incidentally discovered appendicolith on radiological imaging did not develop appendicitis. Hence, the risk of developing acute appendicitis for these patients does not seem higher than the general population

The negative results of Binax should be interpreted with caution and confirmed by rapid molecular tests

FcγRIIB is a T cell checkpoint in antitumor immunity

In the setting of cancer, T cells upregulate coinhibitory molecules that attenuate TCR signaling and lead to the loss of proliferative capacity and effector function. Checkpoint inhibitors currently in clinical use have dramatically improved mortality from melanoma yet are not effective in all patients, suggesting that additional pathways may contribute to suppression of tumor-specific CD8+ T cell responses in melanoma. Here, we show that FcγRIIB, an inhibitory Fc receptor previously thought to be exclusively expressed on B cells and innate immune cells, is upregulated on tumor-infiltrating effector CD8+ T cells in an experimental melanoma model and expressed on CD8+ T cells in patients with melanoma. Genetic deficiency of Fcgr2b resulted in enhanced tumor-infiltrating CD8+ T cell responses and significantly reduced tumor burden. Adoptive transfer experiments of Fcgr2b–/– tumor antigen-specific T cells into FcγRIIB-sufficient hosts resulted in an increased frequency of tumor-infiltrating CD8+ T cells with greater effector function. Finally, FcγRIIB was expressed on CD8+ memory T cells isolated from patients with melanoma. These data illuminate a cell-intrinsic role for the FcγRIIB checkpoint in suppressing tumor-infiltrating CD8+ T cells

Deceased-donor organ transplantation: knowledge and attitudes among health care professionals managing critically ill patients in Karachi

Objectives: Adequate knowledge and positive attitudes of health care professionals regarding deceased-donor organ transplants lead to higher donation consent rates. This study assessed the knowledge and attitudes of health care professionals toward this issue in the light of recent organ transplant legislation in Pakistan. Materials and Methods: Health care professionals in critical care areas of 2 hospitals in Karachi were selected (n=243) and asked to complete a questionnaire regarding their knowledge and attitudes toward deceased-donor organ transplants. Results: In all, 58.8% of the participants were physicians and 41.2% were nurses; 91.4% correctly identified brain death; 51.5% expressed support for deceased-donor organ transplants; 56.8% had concerns of religious rulings against deceased organ donation; 67.5% felt that a government body could not run such a system fairly; 56.4% of the respondents would consider receiving a deceased-donor organ if needed, but only 35.3% would donate after their own death. Only 42.7% and 37% were willing to approach patients and families for consent for a deceased-donor organ transplant, respectively. Most of those unwilling felt that the patient could refuse, become upset and aggressive, and lose trust in the health care professionals. Conclusions: Before implementing a deceased-donor organ transplant system in hospitals, health care professionals should attend a training program regarding their concerns. This would increase motivation when approaching patients/patients’ families for consent, thus increasing deceased-donor consent rates
