Outcomes and Cost-Analysis of Open Versus Endovascular Abdominal Aortic Aneurysm Repair in a Developing Country: A 15-year Experience at a Tertiary Medical Center.

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) has become the most common procedure for treating abdominal aortic aneurysms based on multiple studies conducted in the western world. The implication of such findings in developing countries is not well demonstrated. The objective of this study was to compare medical outcomes and costs of EVAR and open surgical repair (OSR) in a developing country. METHODS: This is a retrospective study of all patients undergoing elective abdominal aortic aneurysm repair between 2005 and 2020 at a tertiary medical center in a developing country. Medical records were used to retrieve demographics, comorbidities, and perioperative complications. Medical records were also used to provide data on the need of reintervention, date of last follow-up, and mortality. RESULTS: The study included a total of 164 patients. Median follow-up time was 41 months. The mean age was 69.9 +/- 7.84 years and 90.24% (n = 148) of patients were males. Regarding long-term mortality outcomes, no significant difference was detected between both groups; OSR patients had a survival rate of 91.38% and 74.86% at 5 and 10 years, compared to 77.29% and 56.52% in the EVAR group (P value = 0.10). Both groups had comparable long-term reintervention rates (P value = 0.334). The OSR group was charged significantly less than the EVAR group ($27,666.35 vs. $44,528.04, P value = 0.008). CONCLUSIONS: OSR and EVAR have comparable survival and reintervention outcomes. Unlike what was reported in developed countries, patients undergoing OSR in countries with low hospital stay costs incur lower treatment costs.

Mass casualty management during a pandemic surge: The American University of Beirut Medical Center experience.

Mass casualty incidents can be devastating events associated with a large number of fatalities, morbidities, and long-lasting sequelae. The negative outcomes can be further amplified if the incident occurred during a pandemic surge, such as what occurred in Beirut, Lebanon with the August 4, 2020 Beirut Port explosion. To decrease the mortality and morbidity and avoid inefficiency, management depends on having an established coordinated multidisciplinary approach from transport and triage to emergency department care and in-hospital management. In this article, the mass casualty management and the impact of the coronavirus disease 2019 pandemic will be discussed based on the American University of Beirut Medical Center experience.

Integrated care for pregnant women on methadone maintenance treatment: Canadian primary care cohort study.

OBJECTIVE: To describe the characteristics of a national cohort of pregnant women on methadone maintenance treatment (MMT) and to provide treatment outcome data for integrated care programs. DESIGN: Retrospective chart review. SETTING: Three different integrated care programs in geographically distinct cities: the Toronto Centre for Substance Use in Pregnancy in Toronto, Ont; the Herzl Family Practice Centre in Montreal, Que; and the Sheway clinic in Vancouver, BC. PARTICIPANTS: Pregnant women meeting criteria for opioid dependence and attending an integrated care program between 1997 and 2009. Women were excluded if they were on MMT only for chronic pain. MAIN OUTCOME MEASURES: Patient demographic characteristics, concurrent medical and psychiatric disorders, and substance use outcome data. RESULTS: A total of 102 opioid-dependent pregnancies were included. The mean age was 29.7 years and 64% of women were white. Women in Montreal were more likely to have partners and had fewer children. Differences in living and housing situations among the sites tended to resolve by the time of delivery. Almost half of this cohort tested positive for hepatitis C. Women had a high prevalence of depression and anxiety across all sites. Half of this cohort was on MMT before conception and for the other half, MMT was initiated at a mean gestational age of 20.7 weeks, resulting in a mean dose of 82.4 mg at delivery. At the first visit, polysubstance use was common. Prescription opioid use was more frequent in Toronto and heroin use was more prevalent in Vancouver and Montreal. For the entire population, significant reductions were found by the time of delivery for illicit (P < .001) and prescription opioids (P = .001), cocaine (P < .001), marijuana (P = .009), and alcohol use (P < .001). CONCLUSION: Despite geographic differences, all 3 integrated care programs have been associated with significant decreases in substance use in pregnant opioid-dependent women.

Risk of preeclampsia in HIV-positive pregnant women receiving HAART: a matched cohort study.

OBJECTIVE: We sought to determine whether HIV-positive women receiving highly active anti-retroviral therapy (HAART) are at higher risk for preeclampsia than HIV-negative women. Secondary outcomes included comparing the risks of preterm birth, low birth weight, and small for gestational age birth in these women. METHODS: In this retrospective matched cohort study, we compared the pregnancy outcomes of HIV-positive women treated with HAART with those of HIV-negative women who gave birth at Mount Sinai Hospital, Toronto, Ontario. Data were ascertained through chart review. Univariate and multivariate logistic regression models were used to compare pregnancy outcomes between the two groups. RESULTS: Ninety-one HIV-positive pregnant women receiving HAART and 273 HIV-negative pregnant women were identified. After adjusting for confounding factors, there was no difference between HIV-positive and HIV-negative women in the odds of preeclampsia (3.3% vs. 5.1%; adjusted odds ratio [aOR] 0.59; 95% CI 0.11 to 3.08), preterm birth (15.6% vs. 11.4%; aOR 1.70, 95% CI 0.79 to 3.66) or small for gestational age infants (20.2% vs. 8.8%; aOR 2.08, 95% CI 0.89 to 5.24). HIV-positive women treated with HAART had increased odds of giving birth to a low birth weight infant compared to HIV-negative women (20.2% vs. 9.9%; aOR 2.91; 95% CI 1.47 to 5.78). CONCLUSION: In this cohort, HIV-positive women on HAART did not demonstrate a higher risk of preeclampsia, preterm birth, or small for gestational age infants; however, they did have a higher risk of having low birth weight infants.
