RESUMO

Desde 2007, el Servicio de Epidemiología e Infectología, ha implementado un programa de transición que busca optimizar la atención de los adolescentes con infección por el HIV durante el paso de la atención pediátrica a la de adultos. Objetivo: Describir las características clínicas, epidemiológicas, virológicas y psicosociales de los adolescentes con infección HIV atendidos en el Programa y analizar el proceso de transición. Materiales y Métodos: Estudio de cohorte retrospectivo. Se incluyeron a los adolescentes, atendidos en el Programa de Transición entre enero de 2019 y diciembre de 2023, en el Hospital Garrahan, con al menos un resultado de CV y CD4+ en ese período. Se obtuvo la información de la historia clínica electrónica y se analizaron variables clínicas, epidemiológicas, virológicas, terapéuticas y psicosociales. Resultados: Se incluyeron 124 pacientes. La vía de transmisión fue vertical en el 92,74% y el estadio clínico e inmunológico era avanzado. En el momento de la transición 77,4% se encontraban con supresión virológica y con recuperación inmunológica. El 55,6% ya realizó la transición a un centro de adultos, 31,4% continúan en el programa, 11,3% se perdieron en el seguimiento y 1,7% fallecieron. Se recopilaron los datos de 31 pacientes transferidos. La mediana de seguimiento fue de 2 años; 25 pacientes (80,6%) continúan en seguimiento. Conclusiones: A pesar de la pandemia de COVID-19, el programa logró la retención de los adolescentes con infección por HIV y una transferencia sostenida en el tiempo. Además de un programa de transición estructurado para garantizar una atención continua y de calidad, es necesario continuar evaluando la evolución postransición (AU)

Since 2007, the Epidemiology and Infectious Diseases Department has implemented a transition program to optimize the care of adolescents with HIV infection during their transition from pediatric to adult care. Objective: To describe the clinical, epidemiological, virological, and psychosocial characteristics of adolescents with HIV infection treated in the program and to analyze the transition process. Materials and Methods: A retrospective cohort study was conducted. Adolescents followed in the Transition Program at Garrahan Hospital between January 2019 and December 2023, with at least one viral load and CD4+ result during that period, were included. Information was obtained from electronic medical records, and clinical, epidemiological, virological, therapeutic, and psychosocial variables were analyzed. Results: A total of 124 patients were included. The route of transmission was vertical in 92.74%, and the clinical and immunologic stage was advanced. At the time of transition, 77.4% were virologically suppressed and had achieved immunologic recovery. Of the patients, 55.6% had already transitioned to an adult center, 31.4% were still in the program, 11.3% were lost to follow-up, and 1.7% died. Data were collected from 31 transferred patients, with a median follow-up of 2 years; 25 patients (80.6%) remain in follow-up. Conclusions: Despite the COVID-19 pandemic, the program successfully retained HIVinfected adolescents and ensured sustained transition over time. In addition to a structured transition program to ensure continuous and quality care, it is necessary to continue evaluating post-transition outcomes (AU)

RESUMO

Discovery and clinical development of monoclonal antibodies with the ability to interfere in the regulation of the immune response have significantly changed the landscape of oncology in recent years. Among the active agents licensed by the regulatory agencies, nivolumab and pembrolizumab are paradigmatic as the most relevant ones according to the magnitude of available data derived from the extensive preclinical and clinical experience. Although in both cases the respective data sheets indicate well-defined dosage regimens, a review of the literature permits to verify the existence of many issues still unresolved about dosing the two agents, so it must be considered an open question of potentially important consequences, in which to work to improve the effectiveness and efficiency of use.

RESUMO

PURPOSE: Type 2 diabetes (T2D) and low serum concentration of high-density lipoprotein cholesterol (HDL-c) are common coexisting metabolic disorders. ABCA1 variants have been shown to be associated to these conditions. We sought to test the combined effect of two ABCA1 gene common variants, rs2422493 (- 565C > T) and rs9282541 (R230C) on HDL-c levels and T2D risk. METHODS: Path analysis was conducted in 3,303 Mexican-mestizos to assess the specific contributions of rs2422493 and rs9282541 ABCA1 variants, insulin resistance, waist-to-height ratio (WHtR), and age on HDL-c levels and T2D risk. Participants were classified into four groups according to their ABCA1 variants carrier status: (i) the reference group carried wild type alleles for both ABCA1 variants (-/-), (ii) +/- were carriers of rs2422493 but non-carriers of rs9282541, (iii) -/+ for carriers of rs9282541 but not carriers of rs2422493 and (iv) carriers of minor alleles for both SNPs (+/+). Principal components from two previous genome-wide association studies were used to control for ethnicity. RESULTS: We identified significant indirect effects on T2D risk mediated by HDL-c in groups -/+ and +/+ (ß = 0.04; p = 0.03 and ß = 0.06; p < 0.01, respectively) in comparison to the -/- reference group. Low concentrations of HDL-c were directly and significantly associated with increased T2D risk (ß = -0.70; p < 0.01). WHtR, male gender, age, and insulin resistance were also associated with T2D risk (p < 0.05). There was no significant direct effect for any of the ABCA1 groups on T2D risk: p = 0.99, p = 0.58, and p = 0.91 for groups +/-, -/+, and +/+ respectively. CONCLUSIONS: The ABCA1 rs9282541 (R230C) allele is associated with T2D in Mexicans through its effect on lowering HDL-c levels. This is the first report demonstrating that HDL-c levels act as an intermediate factor between an ABCA1 variant and T2D.

RESUMO

El Edema Pulmonar Agudo Cardiogénico es un cuadro clínico frecuente en los servicios de urgencia y conlleva una alta mortalidad, y junto a otras complicaciones de la insuficiencia cardíaca podría continuar incrementándose con los años. Los avances en la evaluación y el manejo de esta patología en el Servicio de Urgencia se centran en la utilidad de la ultrasonografía al lado del paciente, en la utilización apropiada de la farmacoterapia existente y la aplicación de herramientas de soporte ventilatorio que anticipen y eviten la necesidad de intubación oro-traqueal y ventilación mecánica.

Acute cardiogenic pulmonary edema is a medical condition often seen in the emergency department. It has high mortality and, as with other complications of heart failure, its incidence may continue to rise in the future. Advances in the evaluation and management of this pathology in the emergency department focus on the benefit of bedside ultrasound, the appropriate use of existing pharmacotherapy and the use of ventilation support equipment that anticipate and avert the need for orotracheal intubation and mechanical ventilation.

RESUMO

OBJECTIVE: To evaluate renal function in renal cancer patients undergoing radical nephrectomy (RN) or partial nephrectomy (PN) (open or laparoscopic - ORN, OPN, LRN or LPN) and to identify risk factors contributing to renal function loss. METHODS: We analysed 228 consecutive renal cancer patients admitted for OPN, LPN, ORN or LRN. The variables analysed were age, gender, weight, type of surgery (radical versus partial), type of surgical access (open versus laparoscopic), preoperative renal function and history of hypertension, diabetes or malignancy. Absolute renal function was calculated as the difference in glomerular filtration rate (ΔGFR) between the renal function before (GFR0) and 12 months after surgery (GFR12). The relative renal function of patients undergoing PN and RN was evaluated by the change in chronic kidney disease stage. RESULTS: LRN caused the greatest loss in absolute renal function, followed by ORN, LPN and OPN. A GFR of ≥60 ml/min was noted for 90 (68.7%) patients before and 65 (49.6%) patients after RN and for 80 (82.5%) patients before and 74 (76.3%) patients after PN. The chronic kidney disease stage dropped to 4 or 5 in the case of 6 (4.6%) patients who underwent RN and 2 (2.1%) patients who underwent PN. Multivariate analysis revealed that only preoperative weight and type of surgery (radical versus partial) had a significant impact on renal function. CONCLUSION: Renal function significantly decreased in patients undergoing RN, irrespective of the access route. Patients with preoperative poor renal function are at risk of postoperative end-stage renal disease.

RESUMO

Inadequate access to prenatal services has been associated with higher rates of mother and child mortality and premature births in the general population. Thus, this paper aims to compare the utilization and adequacy of prenatal care services of Dominican immigrant mothers with that of Puerto Rican mothers. Data was extracted from birth certificates using a cohort from 1998 to 2002 (n = 252, 919). The Kotelchuck index for adequate prenatal care was used for comparison with socio-demographic characteristics of the population. Less than half of Dominican mothers (48.5 %) received adequate prenatal care compared to more than two-thirds (69.1 %) of Puerto Rican mothers (p < .001). After controlling for demographic characteristics, health insurance, pregnancy risks, complications and previous birth (parity) the odds of receiving adequate care of Dominican mothers was 0.7 that of Puerto Rican mothers (p < .001). These results suggest significant disparities in obtaining adequate prenatal care services among migrant women and native Puerto Ricans.

RESUMO

OBJECTIVE: The aim of this study is to measure the knowledge regarding the new sanitation water system being implemented in Dessources, a rural community in the municipality of Croix-des-Bouquets in Haiti after a two-year intervention programme. DESIGN AND METHODS: A cross-sectional epidemiologic design was used to measure the knowledge of the people in the community using a semi-structured questionnaire. Data collection followed a face-to-face interview process in all houses of the community. The instrument content validity was performed by a panel of experts followed by Cronbach's alpha test to establish the reliability of knowledge scale. In addition, association measures were done using Stata 11.0 statistical package. RESULTS: Content validity test were performed with minimum changes and an alpha of 0.74 was obtained for the scale. Response rate was 65.57% (41/60 houses); non-participants were only those who did not meet the inclusion criteria. Most of the participants (77.5%) were 21-49 years old and 85% had been living in the community for more than 20 years. Bivariate analysis showed that the people of Dessources had adequate knowledge. Significant differences, however, were found among the zones that are not in use of the new sanitary systems and among families with more than seven members per house. CONCLUSIONS: Differences found can be explained based on the Rogers theoretical diffusion of innovation model. The evaluation shows that people of Dessources in Haiti have a high knowledge regarding the new water sanitation system and provided evidence of an adequate health education programme intervention.
