Background:COVID 19 is an infectious disease caused by SARS-CoV-2 that has affected Peru on a large scale. Potential clinical and/or epidemiological factors that are related to the positivity of SARS-CoV-2 in the high Andean population are not documented. Objective: To determine factors associated with positivity of SARS-CoV-2 in people living in Ancash. Material and methods: Analytical transversal study. We used the records of patients treated for suspected COVID-19 in a public hospital in Huaraz in March-May 2020. Prevalence ratios (PR) with confidence intervals were estimated. In simple regression analysis, prevalence ratios and 95% confidence intervals were estimated, using Poisson distribution family, log-link function and robust variance. Out of 903 patients, Results: 13.7% tested positive for SARS-CoV-2. In simple regression, male (RP=2.98), cough (RP=2.27), respiratory distress (RP=2.97), diarrhea (RP=2.69), general malaise (RP=1.82), odynophagia (RP=1.69) were positively associated with having a positive SARS-CoV-2 test. In the multiple regressions, the association was maintained in four characteristics: being male (RP=2.7), having a cough (RP=1.45), respiratory distress (RP=2.15), and diarrhea (RP=1.89). Conclusion: In high Andean areas, most positive cases present typical symptoms. The factors associated with positivity were male sex and the presence of cough, respiratory difficulty and diarrhea.

Nonsteroidal anti-inflammatory drug effectivity in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis: A systematic review and meta-analysis.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for the treatment of diseases affecting the biliary tree and pancreatic duct. Although the therapeutic success rate of ERCP is high, the procedure can cause complications, such as acute pancreatitis [post-ERCP pancreatitis (PEP)], bleeding and perforation. AIM: To assess the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in preventing PEP during follow-up. METHODS: Databases such as MEDLINE, EMBASE and Cochrane Central Library were searched. Only randomized controlled trials (RCTs) comparing the efficacy of NSAIDs and placebo for the prevention of PEP were included. Outcomes evaluated included the incidence of PEP, severity of pancreatitis, route of administration, types, dose, and timing of administration of NSAIDs. RESULTS: Twenty-six RCTs were considered eligible with a total of 8143 patients analyzed. Overall, 4020 patients used NSAIDs before ERCP and 4123 did not use NSAIDs (control group). Ultimately, 298 cases of post-ERCP acute pancreatitis were diagnosed in the NSAID group and 484 cases in the placebo group. The risk of PEP was lower in the NSAID group risk difference (RD): -0.04; 95% confidence interval (CI): -0.07 to - 0.03; number needed to treat (NNT), 25; P < 0.05. NSAID use effectively prevented mild pancreatitis compared to placebo use (2.5% vs 4.1%; 95%CI: -0.05 to -0.01; NNT, 33; P < 0.05), but information on moderate PEP and severe PEP could not be fully elucidated. Only rectal administration reduced the incidence of PEP with RD: -0.06; 95%CI: -0.08 to -0.04; NNT, 17; P < 0.05). Furthermore, only the use of diclofenac or indomethacin was effective in preventing PEP, at a dose of 100 mg, which must be administered before performing ERCP. CONCLUSION: Rectal administration of diclofenac and indomethacin significantly reduced the risk of developing mild PEP. Additional RCTs are needed to compare the efficacy between NSAID routes of administration in preventing PEP.

Factores pronóstico de supervivencia en adultos por gliomas de alto grado en un hospital de Lima, Perú / Prognostic Factors And Survival Study In High-Grade Glioma In A Hospital In Lima, Peru

Introducción: Los Gliomas son tumores primarios del sistema nervioso central. Son clasificados del I-IV grado, siendo los de alto grado el III y IV los más frecuentes y de pobre pronostico. Objetivo: Determinar los factores pronósticos de supervivencia en pacientes por gliomas de alto grado en un hospital de Lima, Perú. Métodos: Se revisaron retrospectivamente las historias clínicas con glioma de alto grado del 2010-2014, se analizaron diez variables; con graficas de supervivencia de Kaplan-Meiery Long-rank y el modelo de regresión de Cox. Resultados: De un total de 278 pacientes con gliomas de alto grado 136 fueron varones y 142 mujeres. El análisis de la Supervivencia Libre de Progresión(SLP) tuvo un rango de 5,6-80,3 (mediana 22,7) y el análisis de supervivencia global (PS) tuvo un rango de 4-83,2 (mediana 26,2) meses. La supervivencia global para el tumor de IV grado fue 15,7 meses (IC95% 14,2-17,1); el III grado fue de 38,4 meses (IC 95% 35,8-40,9). El grado (PS: HR 15; SLP: HR 25,1); el tratamiento quirúrgico (PS: HR 0,6; SLP: HR 0,49), edad (PS: HR 1,47; SLP: HR 1,7), tratamiento adyuvante(PS: HR 0,6; SLP: HR 0,58) y karnofsky (PS: HR 0,7) tuvieron correlación; mientras el Karnofsky para SLP no (P=0,146). Conclusión: La edad, el estado funcional, el tratamiento quirúrgico, el tratamiento adyuvante y el grado del tumor son factores pronósticos de PS; en contraste, para SLP los factores pronósticos fueron la edad, tratamiento quirúrgico, tratamiento adyuvante y el grado del tumor.

Introduction: Gliomas are primary tumors of the central nervous system. They are classifiedfrom grade I-IV, with high grade III and IV being the most frequent and with poor prognosis. Objective: To determine the prognostic factors of survival in patients with high-gradegliomas in a hospital in Lima, Peru. Methods: The medical records with high-grade gliomafrom 2010-2014 were retrospectively reviewed, ten variables were analyzed with Kaplan-Meier and Log Rank survival graphs and the Cox regression model. Results: Out of a total of278 patients with high-grade gliomas, 136 were men and 142 women. The analysis of Progression-Free Survival (SLP) had a range of 5.6-80.3 (median 22.7) and the analysis ofoverall survival (PS) had a range of 4-83.2 (median 26, 2 months. The overall survival for theIV grade tumor was 15.7 months (95% CI 14.2-17.1); the III degree was 38.4 months (95%CI 35.8-40.9). The grade (PS: HR 15; SLP: HR 25.1); surgical treatment (PS: HR 0.6; SLP:HR 0.49), age (PS: HR 1.47; SLP: HR 1.7), adjuvant treatment (PS: HR 0.6; SLP: HR 0 , 58)and karnofsky (PS: HR 0.7) were correlated; while the Karnofsky for SLP does not (P =0.146). Conclusion: age, functional status, surgical treatment, adjuvant treatment, and tumorgrade are prognostic factors for PS. In contrast, for SLP the prognostic factors were age,surgical treatment, adjuvant treatment, and tumor grade.

Five Year Results of the French EPI-ANA-01 Registry of AnacondaTM Endografts in the Treatment of Infrarenal Abdominal Aortic Aneurysms.

OBJECTIVE: A significant decrease in aneurysm related survival is observed at long term follow up after infrarenal endovascular aneurysm repair (EVAR) compared with open repair. Therefore, longer term results with new generation endografts are essential. The aim of this post-approval French multicentre prospective observational study (EPI-ANA-01) was to evaluate the technical success and five year mortality and secondary intervention rates of the third generation AnacondaTM endograft. METHODS: From June 2012 to October 2013, 176 consecutive unruptured infrarenal abdominal aortic aneurysms were included (160 male patients, mean age 75.3 ± 8.4 years). Survival, freedom from type Ia endoleak, limb events, and re-interventions were estimated using the Kaplan-Meier method. Anatomical and clinical characteristics were compared according to the occurrence of migration, conversion, adverse limb events, endoleak, and sac enlargement. RESULTS: The primary technical and clinical success rates were 98.3% and 94.9%, respectively. A hostile neck was identified in 33.9% of patients and 10.7% were treated outside instructions for use (IFU). An early post-operative (≤30 days) mortality rate of 1.7% was observed. At one and five years, respectively, the overall survival rate was 94.9% and 65.9% (aneurysm related in four patients [2.3%]) and the clinical success rate was 90.9% and 70.6%. Secondary interventions were performed in 35 of 176 patients (19.9%). The overall limb occlusion rate was 7.9% and the aneurysm sac diameter decreased significantly (pre-operative diameter 53.9 ± 8.6 mm vs. 42.3 ± 14.7 mm at five years; p < .001). Patients treated outside the instructions for use (IFU) had significantly higher rates of migration, surgical conversion, and aneurysm sac expansion (p = .03). CONCLUSION: The Anaconda endograft provides high technical success and satisfactory five year aneurysm exclusion and clinical success rates. However, implantation outside the IFU should be avoided, as it leads to significantly worse outcomes, and caution over the risk of limb occlusion and distal embolisation should be observed.
