RESUMO
PURPOSE: Breast cancer mortality rates in Latin America (LA) are higher than those in the United States, possibly because of advanced disease presentation, health care disparities, or unfavorable molecular subtypes. The Latin American Cancer Research Network was established to address these challenges and to promote collaborative clinical research. The Molecular Profiling of Breast Cancer Study (MPBCS) aimed to evaluate the clinical characteristics and treatment outcomes of LA participants with locally advanced breast cancer (LABC). PATIENTS AND METHODS: The MPBCS enrolled 1,449 participants from Argentina, Brazil, Chile, Mexico, and Uruguay. Through harmonized procedures and quality assurance measures, this study evaluated clinicopathologic characteristics, neoadjuvant chemotherapy response, and survival outcomes according to residual cancer burden (RCB) and the type of surgery. RESULTS: Overall, 711 and 480 participants in the primary surgery and neoadjuvant arms, respectively, completed the 5-year follow-up period. Overall survival was independently associated with RCB (worse survival for RCBIII-adjusted hazard ratio, 8.19, P < .001, and RCBII [adjusted hazard ratio, 3.69, P < .008] compared with RCB0 [pathologic complete response or pCR]) and type of surgery (worse survival in mastectomy than in breast-conserving surgery [BCS], adjusted hazard ratio, 2.97, P = .001). The hormone receptor-negative-human epidermal growth factor receptor 2-positive group had the highest proportion of pCR (48.9%). The analysis of the ASCO Quality Oncology Practice Initiative breast module revealed high compliance with pathologic standards but lower adherence to treatment administration standards. Notably, compliance with trastuzumab administration varied widely among countries (33.3%-88.7%). CONCLUSION: In LABC, we demonstrated the survival benefit of BCS and the prognostic effect of the response to available neoadjuvant treatments despite an important variability in access to key treatments. The MPBCS represents a significant step forward in understanding the real-world implementation of oncologic procedures in LA.

Resumen Introducción: La sepsis pediátrica continúa siendo una causa importante de mortalidad en países de bajos y medianos ingresos, su reconocimiento temprano en emergencias requiere del uso de criterios que nos permitan predecir anticipadamente la gravedad del paciente. Objetivo: nuestro estudio pretende comparar los criterios de SIRS y qSOFA en cuanto a su capacidad discriminatoria en mortalidad en sepsis pediátrica. Métodos: realizamos un estudio multicéntrico, prospectivo en servicios de emergencias incluyendo niños con sospecha de sepsis subsecuentemente ingresados a UTIP, en los cuales se evaluaron los puntajes en SIRS y qSOFA comparándolos con los resultados al egreso. Resultados: se enrolaron 64 pacientes, admitidos en estadios de Sepsis (19%), Shock Séptico (20,6%) y con Disfunción Multiorgánica (60,4%), con una mortalidad respectivamente de 9,5%, 14,3% y 76,2%; en 33,9% de los casos se pudo rescatar algún germen. Evaluando los criterios SIRS vemos que la ausencia de ellos se asocia con mayor sobrevivencia (p=0,044; OR 0,618: IC95% 0,5020,761), Por otro lado, 2 o más criterios qSOFA se asocia con mayor mortalidad (p=0,047; OR 3,52: IC95% 1,090-11,371). Conclusión: ambos criterios utilizados para definir sepsis en pediatría demostraron su utilidad, el uso del score qSOFA dada a su estrecha relación con la mortalidad puede emplearse para anticipar alteraciones orgánicas potencialmente mortales.
Abstract Introduction: Pediatric sepsis continues to be one of the main causes of mortality in low and middle-income countries, its early recognition in emergencies requires the use of criteria that allow us to predict the severity of the patient. Objective: our study aims to compare the SIRS criteria and qSOFA regarding its discriminatory capacity in mortality in children with sepsis. Methods: a prospective multicenter study was carried out in emergency services enrolling children with suspected sepsis subsequently admitted to the PICU, in which the scores in qSOFA and SIRS were evaluated comparing them with the results at hospital discharge. Results: 64 patients were enrolled, admitted in emergency in Sepsis (19%), Septic Shock (20.6%) and with Multiple Organ Dysfunction (60.4%) stage, with a mortality respectively of 9.5% and 14.3% and 76.2%; germ could be rescued in 33.9% of the cases; Evaluating the SIRS criteria, we see that the absence of them is associated with lower mortality (p = 0.044; OR 0.618: 95% CI 0.502-0.761); otherwise, 2 or more qSOFA criteria are associated with higher mortality (p = 0.047 ; OR 3.52: 95% CI 1.090-11.371). Conclusion: both criteria used to define sepsis in pediatrics demonstrated their usefulness, the use of the qSOFA score given its close relationship with mortality can be used to anticipate life-threatening organ alterations.
RESUMO
Objetivos del trabajo: Se determinaron los porcentajes de las lesiones precancerosas de cuello uterino en un grupo de mujeres diagnosticadas positivas por la prueba ADN-VPH. Materiales y métodos: El presente estudio es un análisis exploratorio descriptivo transversal de una base de datos con resultados de las pruebas de ADN-VPH (genotipo y tipo de infección), citología y colposcopia, realizadas en 58 mujeres de 30 años o más, para el periodo de octubre del 2018 a febrero del 2019. Resultados: De las 58 mujeres positivas para la prueba ADN-VPH, el 57% (n=33) fueron positivas para la prueba citológica cervical. De este grupo de mujeres fueron diagnosticadas negativas para LEI el 21% (n=7); para LEI-BG el 33% (n=11); y para LEI-AG el 45% (n=15) mediante la prueba de colposcopia. El VPH-16 mostró la mayor frecuencia relativa de detección en las LEI-AG con un 46,7% (n=7). Igualmente, los genotipos que cubre la vacuna Gardasil_4 fueron identificados en mayor porcentaje en las LEI-AG en comparación con los otros tipos histopatológicos diagnosticados, siendo esta asociación estadísticamente significativa, valor de p = 0,033. Conclusiones: La implementación de la nueva guía de práctica clínica para la detección y manejo de lesiones precancerosas de cuello uterino muestra resultados satisfactorios, siendo concordante la detección de ADN-VPH, con la identificación de anormalidades citológicas e histopatológicas, permitiendo la identificación precoz de mujeres en riesgo de desarrollar cáncer cervical.
Objectives of the study: To determine the percentages of precancerous lesions in the cervix in a group of women with positive diagnostic to the DNA-HPV test. Materials and methods: The present study is a cross-sectional exploratory analysis of a database with information on the results of DNA-HPV tests (genotype and type of infection), cytology and colposcopy, carried out on 58 women aged 30 or older, for the period from October 2018 to February 2019. Results: Of the 58 women positive for the DNA-HPV test, 57% (n=33) were positive for the cervical cytology test. Of this group of women, 21% (n=7) were diagnosed LEI-negative; for LEI-BG 33% (n=11); and for LEI-AG, 45% (n=15) using the colposcopy test. HPV-16 has a higher detection frequency in the LEI-AG with 46.7% (n=7). Likewise, the genotypes that cover the Gardasil_4 vaccine were members in a greater percentage in the LEI-AG in comparison with other diagnosed histopathological types, this association being statistically significant, value of p = 0.033. Conclusions: The implementation of the new clinical practice guideline for the detection and management of precancerous lesions of the cervix shows satisfactory results, the DNA-HPV detection being consistent, with the identification of cytological and histopathological abnormalities, allowing the early identification of women at risk to develop cervical cancer.

Background: Hip fractures (HFx) are an important geriatric syndrome, with a high incidence in developing countries. Aim: To describe characteristics of a group of Chilean patients with HFx. Patients and Methods: In a cross-sectional study we included patients aged 60 years or more with a HF admitted to an orthopedic service along three years. Age, incidence, location, seasonality, hospital stay, time between HFx and surgery, mortality, prior treatment for osteoporosis, anatomical location, etiology and type of surgery were evaluated. Results: We reviewed 647 patients with a median age of 81 years (76% women). The calculated incidence of hip fracture for people aged ≥ 65 years was 177/100,000. Sixty six percent of fractures were extracapsular. Mean hospital stay was 17 days and the mean lapse between the fracture and surgery was 19 days. Eighty four percent of patients had osteoporosis and only 5% were receiving treatment. Eighty three percent of patients were operated. Osteosynthesis was mainly used for extracapsular fractures and arthroplasty for intracapsular lesions. Intracapsular HFx tended to occur more commonly during warm seasons (Odds ratio = 1.534). Mortality at one year was 24%. It was higher among non-operated patients in whom the proportion of males and number of comorbidities were significantly higher. Conclusions: A high proportion of patients with HFx have osteoporosis albeit a reduced number is receiving treatment. Non-operated patients had a higher risk profile and higher mortality.

Background: Metabolic syndrome is a risk factor for cardiovascular diseases and cancer. Its frequency is increasing steadily Aim: To evaluate the prevalence of metabolic syndrome (MS) and its components in a 10-year tracking study of young adults. Material and Methods: Concurrent cohort study of subjects born between 1974 and 1978. They were evaluated between 2000 and 2002 and between 2010 and 2012 to determine the frequency of MS and its components (high blood glucose, waist circumference [WC], triglycerides, blood pressure and low HDL cholesterol), according to ATP III criteria. Attrition was handled using the reciprocal of the probability of remaining in the study. Result: During the first evaluation, the prevalence of metabolic syndrome was 9.3%, confidence interval (CI): 7.5-11.1), with no gender differences. Ten years later, the prevalence of MS increased significantly to 27.6% (CI: 24.7-29.9) and was more common in women than men (30.4 and 23.8% respectively, p < 0.014). The components of MS also increased from one period to another: hyperglycemia, from 5.2% (CI: 4-7) to 24.4% (CI: 22-27); high triglyceride levels from 17.6% (CI: 15-20) to 35.3% (CI: 32-38); high blood pressure from 14.7 (CI: 13-18) to 30.2% (IC: 28-33) and high WC: 16.9% (CI: 15-19) to 41.5% (CI: 39-45). In both evaluations, there was a greater frequency of high triglycerides and high blood pressure among men, and greater frequency of low HDL and high WC among women. Hyperglycemia only showed differences by gender in the second measurement, and was greater among men. Conclusions: There was a marked increase in metabolic syndrome and its components in a 10-year interval, which is a warning sign of future cardiovascular risk.
