RESUMEN
Patient-centered medical home (PCMH) is a concept of a team of providers caring for a panel of patients with the goals to improve the quality of care while simultaneously decreasing the cost of that care. The clinical evidence that the PCMH approach achieves either goal is mixed. More studies are in progress that will provide more data.

INTRODUCTION: Stress among medical students induced by academic pressures is on the rise among the student population in Pakistan and other parts of the world. Our study examined the relationship between two different systems employed to assess academic performance and the levels of stress among students at two different medical schools in Karachi, Pakistan. METHODS: A sample consisting of 387 medical students enrolled in pre-clinical years was taken from two universities, one employing the semester examination system with grade point average (GPA) scores (a tiered system) and the other employing an annual examination system with only pass/fail grading. A pre-designed, self-administered questionnaire was distributed. Test anxiety levels were assessed by The Westside Test Anxiety Scale (WTAS). Overall stress was evaluated using the Perceived Stress Scale (PSS). RESULTS: There were 82 males and 301 females while four did not respond to the gender question. The mean age of the entire cohort was 19.7 ± 1.0 years. A total of 98 participants were from the pass/fail assessment system while 289 were from the GPA system. There was a higher proportion of females in the GPA system (85% vs. 59%; p < 0.01). Students in the pass/fail assessment system had a lower score on the WTAS (2.4 ± 0.8 vs. 2.8 ± 0.7; p = 0.01) and the PSS (17.0 ± 6.7 vs. 20.3 ± 6.8; p < 0.01), indicating lower levels of test anxiety and overall stress than in students enrolled in the GPA assessment system. More students in the pass/fail system were satisfied with their performance than those in the GPA system. CONCLUSION: Based on the present study, we suggest governing bodies to revise and employ a uniform assessment system for all the medical colleges to improve student academic performance and at the same time reduce stress levels. Our results indicate that the pass/fail assessment system accomplishes these objectives.

BACKGROUND: Coronary artery bypass grafting and percutaneous coronary intervention are revascularization options for significant coronary artery disease. While international data support the use of coronary artery bypass in high-risk groups, regional data on outcomes in these groups are rare. We conducted a retrospective study to determine the outcomes of patients undergoing coronary artery bypass for left main and multivessel disease. METHODS: Two thousand eight hundred and fifty-one patients undergoing coronary artery bypass at the Aga Khan University Hospital from 2006 to 2013 were included; patients undergoing redo surgery were excluded. Demographic data, comorbidities, angiography findings, in-hospital complications, one-month and one-year follow-up were analyzed. RESULTS: Of the 2851 patients, 568 had left main disease (group 1) and 2283 (group 2) had multivessel disease (≥2 vessels excluding the left main). Group 1 had significantly more chronic lung disease, cardiogenic shock, and congestive heart failure than group 2 (p < 0.001); 50.6% of patients were diabetic and 71.8% were hypertensive. Mortality was 5.1% and 2.2% during hospital stay, 6.5% and 2.6% at 30 days, and 6.7% and 2.7% at 1 year in groups 1 and 2, respectively. CONCLUSION: Our comparable results and international data advocate revision of the current practice of using percutaneous coronary intervention over coronary artery bypass in the developing world. Institutional results are essential to determine the outcome of coronary artery bypass in high-risk populations with a high burden of diabetes and hypertension. We noted increased complications and mortality in patients with left main rather than multivessel disease.

OBJECTIVE: To identify the frequency of different types of oral clefts and presence of known risk factors among patients. METHODS: The retrospective review of 292 patients, presenting with oral clefts between 1992 and 2011, was conducted at the Aga Khan University Hospital, Karachi. A pre-designed questionnaire was used to collect details, including demographics, type of cleft, presence of known risk factors, surgical details, and follow-up visits. SPSS 16 was used for data analysis. Chi-square test and analysis of variance was used: whenever applicable. RESULTS: Of the total, 168 (57-53%) patients had cleft lip with or without cleft palate, and 124 (42.5%) had cleft palate alone. The most common defect was left-sided complete cleft lip and palate and midline incomplete cleft palate in the two groups respectively. Consanguinity among the parents was found to be the most common risk factor (n = 50; 17.1%). Median age of repair was 4 months for cleft lip and 10 months for cleft palate in the first group. For the other group, the median age of primary repair was 13 months. First-week follow-up after surgery was 50% (n = 84) for the lip repair, and 65% (n = 81) for palate repair. CONCLUSION: Our review revealed that most patients had cleft lip with or without cleft palate (CL/P). The most common risk factor was consanguinity among parents. Delay in seeking care, low follow-up rates after surgical repair of the anomaly and lack of involvement of speech therapist and orthodontist was observed.
