Seguimiento de niños con diagnóstico de asma grave antes y durante la pandemia por COVID-19 / Follow-up of children diagnosed with severe asthma before and during the COVID-19 pandemic

En la pandemia por COVID-19 se exploraron estrategias de atención para garantizar el seguimiento de niños con asma grave. Estudio prospectivo, observacional, comparativo. Se incluyeron pacientes del programa de asma grave de un hospital pediátrico de tercer nivel (n 74). Se evaluó el grado de control, exacerbaciones y hospitalizaciones durante un período presencial (PP), marzo 2019-2020, y uno virtual (PV), abril 2020-2021. En el PP, se incluyeron 74 pacientes vs. 68 (92 %) del PV. En el PP, el 68 % (46) de los pacientes presentaron exacerbaciones vs. el 46 % (31) de los pacientes en el PV (p 0,003). En el PP, se registraron 135 exacerbaciones totales vs. 79 en el PV (p 0,001); hubo una reducción del 41 %. En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

Analysis of antiretroviral therapy interruption in people living with HIV during the 2010-2021 Period. / [Artículo traducido] Análisis de la interrupción de la terapia antirretroviral en personas que viven con VIH/sida durante el periodo 2010­2021.

OBJECTIVE: In the context of the advancement of antiretroviral therapy and, as the characteristics of people living with HIV progress toward an aging population, understanding the causes of treatment interruption becomes crucial. The aim of the study was to determine the change in reasons for antiretroviral treatment discontinuation for 12 years. Secondarily, compare annual antiretroviral regimen discontinuation rate and factors associated. METHODS: We conducted an analysis using data from people living with HIV who were receiving antiretroviral therapy and discontinued it for any reason. The study included people with HIV infection who visited an outpatient hospital pharmacy clinic from January 2010 to December 2021. Two periods were differentiated for the analysis: 2010-2015 and 2016-2021. The reasons for antiretroviral treatment discontinuation followed classification described by Swiss cohort. In the context of this study, it is pertinent to note that the term 'interruption' will be consistently used in this article to refer to the act of switching or stopping antiretroviral treatment. To examine factors associated with antiretroviral therapy discontinuation, we utilized Kaplan-Meier methods and Cox proportional models. RESULTS: We included 789 people living with HIV, predominantly male (81,5%). The main reason for discontinuation was clinical decision (50.2%) followed by adverse effects (37.9%). Focusing on clinical decision, we observed a trend change that went from antiretroviral treatment simplification regimen (56.1%) in the first part of the period analyzed to the therapeutic optimization (53.6%) in the second half. Furthermore, factors that were statistically significantly associated with antiretroviral treatment discontinuation were people with HIV ≥50 years (HR 1.60; 95%CI 1.25-2.04), post-discontinuation single-tablet regimen (HR 1.49; 95%CI 1.06-2.11) and antiretroviral drug classes. CONCLUSIONS: Over the 12 years there has been a change in the main cause of antiretroviral treatment discontinuation, currently therapeutic optimization being the main reason. Integrase inhibitors-based regimens and singletablet regimen strategies were less likely to be discontinued than others antiretroviral drug classes, allowing for better clinical management due to the efficacy profile, especially in people living with HIV ≥50 years with comorbidities.

Análisis de interconsultas derivadas desde atención primaria y rechazadas por salud mental en el Departamento de Salud Arnau de Vilanova-Llíria (Valencia) / Analysis of Interconsultations Derived from Primary Care and Rejected by Mental Health in the Arnau de Vilanova-Llíria (Valencia) Health Department

En los últimos años se ha constatado un aumento de la demanda asistencial en los servicios de salud mental y, por tanto, un aumento de interconsultas que se reci-ben desde atención primaria, siendo necesario filtrar dichas derivaciones para poder llevar a cabo una atención adecuada. El principal objetivo de este estudio es la evaluación del modelo de derivación del Servicio de Salud Mental del Departamento del Arnau de Vila-nova-Llíria mediante un análisis descriptivo y el seguimiento a lo largo de 6 meses de las interconsultas derivadas desde atención primaria y rechazadas por salud mental en el año 2019. Durante esos meses se recibieron 2029 interconsultas, de las cuales 623 fueron rechazadas, correspondiéndose estas a 504 pacientes. De estas personas, 164 fueron finalmente citadas en salud mental tras realizar una nueva interconsulta. Este análisis pone de manifiesto la necesidad de implementar un modelo colaborativo entre atención primaria y salud mental que se traduzca en una mayor detección de casos, una mejor derivación y, en definitiva, una mejor atención a los y las pacientes.

In recent years, there has been an increase in the demand for care in Mental Health services and, therefore, an increase in interconsultations received from Primary Care, making it necessary to filter said referrals in order to carry out adequate care. The main objective of this study is to evaluate the referral model of the Mental Health Ser-vice of the Department of Arnau de Vilanova-Llíria through the descriptive analysis and follow-up over 6 months of interconsultations derived from Primary Care and rejected by Mental Health in 2019. During those months, 2029 interconsultations were received, of which 623 were rejected, corresponding to 504 patients. Of these patients, 164 were fi-nally attended to in Mental Health after carrying out a new interconsultation. This analysis shows the need to implement a collaborative model between Primary Care and Mental Health that turns into greater cases detection, better referral sand, ultimately, a better patient care.

Linfocitosis monoclonal de células B en familiares de pacientes colombianos con síndromes linfoproliferativos crónicos B

Introducción. La linfocitosis monoclonal de células B, generalmente, precede la leucemia linfocítica crónica y afecta alrededor del 12 % de la población adulta sana. Esta frecuencia se incrementa en familiares de pacientes con síndromes linfoproliferativos crónicos de células B. Objetivo. Determinar la frecuencia de linfocitosis monoclonal B en familiares de pacientes con síndromes linfoproliferativos crónicos B, sus características inmunofenotípicas y citogenéticas, posible relación con agentes infecciosos, y seguimiento a corto plazo de población colombiana. Materiales y métodos. Se estudiaron 50 adultos sanos con antecedentes familiares de síndromes linfoproliferativos crónicos de célula B, empleando citometría de flujo multiparamétrica, pruebas citogenéticas y serológicas, encuesta de hábitos de vida y seguimiento a dos años. Resultados. La frecuencia encontrada de linfocitosis monoclonal B fue del 8 %, con predominio del sexo femenino y edad avanzada, incrementándose al 12,5 % en individuos con antecedentes familiares de leucemia linfocítica crónica. Tres de cuatro individuos presentaron inmunofenotipo de tipo leucemia linfocítica crónica, todas con bajo recuento. A su vez, en estos individuos se observa de manera significativa un mayor número de células/ µl en subpoblaciones linfocitarias T, junto con mayor predisposición a la enfermedad. Las poblaciones clonales descritas aumentan a lo largo del tiempo de manera no significativa. Conclusiones. La frecuencia y comportamiento de la linfocitosis monoclonal de célula B en pacientes con antecedentes familiares de síndromes linfoproliferativos crónicos B es similar a lo encontrado en estudios relacionados, lo que sugiere que no existe afectación de genes de mayor relevancia que puedan desencadenar una proliferación clonal descontrolada, pero que generan desregulación inmunológica que podría indicar un mayor riesgo de infección grave en estos individuos.

Introduction. Monoclonal B-cell lymphocytosis generally precedes chronic lymphocytic leukemia, affecting about 12% of the healthy adult population. This frequency increases in relatives of patients with chronic B-cell lymphoproliferative disorders. Objective. To determine the frequency of monoclonal B-cell lymphocytosis in relatives of patients with chronic B-cell lymphoproliferative disorders, their immunophenotypic/ cytogenetic characteristics, a possible relationship with infectious agents, and short-term follow-up in the Colombian population. Materials and methods. Fifty healthy adults with a family history of chronic B-cell lymphoproliferative disorders were studied using multiparametric flow cytometry, cytogenetic/serological testing, lifestyle survey, and 2-year follow-up. Results. The frequency of monoclonal B-cell lymphocytosis found was 8%, with a predominance of female gender and advanced age, increasing to 12.5% for individuals with a family history of chronic lymphocytic leukemia. Three out of four individuals presented chronic lymphocytic leukemia-type immunophenotype, all with low counts. In turn, a significantly higher number of cells/µΙ is observed in these individuals in T lymphocyte subpopulations, together with a greater predisposition to the disease. The described clonal populations increase over time in a non-significant manner. Conclusions. The frequency and behavior of monoclonal B-cell lymphocytosis in patients with family history of chronic B-cell lymphoproliferative disorders are like those found in related studies, which suggests that there is no involvement of more relevant genes that can trigger uncontrolled clonal proliferation, but that generates immunological deregulation that could justify a greater risk of serious infection in these individuals.

Factors from healthcare delivery affecting breast cancer survival in a health area of Northern of Spain.

OBJECTIVE: Clinical breast cancer decision-making significantly affects life expectancy and management of hospital resources. The aims of the present study were to estimate the time of survival for breast cancer patients and to identify independent factors from healthcare delivery associated with survival rates in a specific health area of Northern of Spain. METHODS: Survival analysis was conducted among a cohort of 2545 patients diagnosed with breast cancer between 2006 and 2012 from the population breast cancer registry of Asturias-Spain and followed up till 2019. Adjusted Cox proportional hazard models were used to identify the independent prognostic factors of all-cause from death. RESULTS: The 5-year survival rate was 80%. Advanced age (>80 years) (hazard ratio, HR: 4.35; 95% confidence interval, CI: 3.41-5.54), hospitalization in small hospitals (HR: 1.46; 95% CI: 1.09-1.97), treatment in oncology wards (HR: 3.57; 95% CI: 2.41-5.27), and length of stay >30 days (HR: 2.24; 95% CI: 1.32-3.79) were the main predictors of death. By contrast, breast cancer suspected via screening was associated with a lower risk of death (HR: 0.55; 95% CI: 0.35-0.87). CONCLUSION: There is room for improvement in survival rates after breast cancer in the health area of Asturias (Northern of Spain). Some healthcare delivery factors, and other clinical characteristics of the tumor influence the survival of breast cancer patients. Strengthening population screening programs could be relevant to increasing survival rates.

During follow-up at one year, 41.2% of the patients were asymptomatic and 57.7% were classified as NYHA II, prosthesis dysfunction was found in 13.3% (the majority due to paravalvular leak). Conclusions : Aortic valve replacement surgery in our setting implies an improvement in quality of life with good functional results, complication rate, and morbidity and mortality comparable with the world literature.

Logro de control metabólico temprano en adultos con diabetes mellitus tipo 2 en Perú

Objetivo: Estimar la proporción de sujetos con diabetes mellitus tipo 2 (DMT2) que alcanzan la meta terapéutica para HbA1C un año después del diagnóstico (control metabólico temprano). Métodos: Revisión retrospectiva de historias clínicas de adultos atendidos en 16 centros médicos distribuidos en nueve ciudades peruanas. Se incluyeron pacientes que recibieron un diagnóstico inicial de DMT2 y tuvieron al menos un año de seguimiento. Se consideraron las metas metabólicas definidas en los estándares ADA 2018. Resultados: Se incluyeron 457 sujetos (53,03% mujeres). Cuando fueron diagnosticados, la edad media fue de 55,75 años (DE ± 12,92), la media de HbA1C fue de 9,10% (DE ± 2,28). Hubo diagnóstico concomitante de hipertensión arterial o de dislipidemia en 27,13% y 52,40%, respectivamente. Al año de seguimiento, 57,76% de los sujetos alcanzó la meta de HbA1C ( 40 mg / dL), 24,31% para HDL-c en mujeres (>50 mg/dL), 48,24% para triglicéridos (<150 mg/dL), y 89,23% para presión arterial (<140/90 mmHg). Conclusiones: En este estudio en condiciones de la vida real, en adultos con DMT2 con un año de seguimiento, el logro de la meta de HbA1C (<7%) se alcanzó en el 58% de los pacientes. Si bien estos resultados son compatibles con los reportados en otros estudios de la región, se evidencia la oportunidad de mejorar el logro temprano de metas con el objetivo de optimizar los resultados a largo plazo.

Aim: To estimate the proportion of subjects with type 2 diabetes mellitus (T2DM) who attain therapeutic goal for HbA1C one year after diagnosis (early metabolic control). Methods: Retrospective review of medical records of adults cared for at 16 centers in nine Peruvian cities. Patients who received an initial diagnosis of T2DM and had at least one year of follow up were included. Metabolic goals were as defined by ADA 2018 standards. Results: 457 subjects were included (53,03% female). At diagnosis, mean age was 55,75 years (SD ± 12.92), mean HbA1C was 9,10% (SD ± 2,28). Concomitant hypertension or dyslipidemia were present in 27,13% and 52,40%, respectively. At one year follow up, 57,76% of subjects attained the goal for HbA1C ( 40 mg/dL), 24,31% for HDL-c in women (>50 mg/dL), 48,24% for triglycerides (<150 mg/dL), and 89,23% for blood pressure (<140/90 mmHg). Conclusions: In this real-life study of adults with T2DM with one year of follow up, metabolic control for HbA1C (<7%) was attained in 58% of subjects. While the results are compatible with those reported in other studies in the region, there is opportunity to further improve early treatment goal attainment to optimize long-term outcomes.

Seguimiento de la paciente con diagnóstico de cáncer de mama. Revisión de la evidencia y abordaje terapéutico en el Instituto Nacionalde Cancerología - Colombia / Follow-up of the patient with breast cancer history. Review of the evidence and approach at the Instituto Nacional de Cancerología - Colombia

Los supervivientes de cáncer se definen como aquellos individuos que han completado su tratamiento inicial y no tienen evidencia de la enfermedad. Para el caso de las pacientes supervivientes de cáncer de mama, el seguimiento involucra no sólo la vigilancia de la recaída locorregional y a distancia, así como la tamización de segundos primarios mamarios, sino también la evaluación de los efectos relacionados con las terapias recibidas. Hoy en día, existe controversia sobre cuál debe ser el método, la frecuencia, la duración y tipo de personal de la salud que realice el seguimiento de estas pacientes. Las guías de las distintas sociedades científicas muestran una variabilidad importante en las recomendaciones a este respecto. Este documento pretende revisar la mejor evidencia disponible sobre los procedimientos para la detección de la recaída locorregional, de las metástasis a distancia, de un segundo cáncer de mama contralateral y de los eventos adversos relacionados con los tratamientos para el cáncer de mama. Adicionalmente, se examinan los porcentajes y sitios de recidiva tumoral con relación al estadio clínico y a la biología tumoral

Cancer survivors are defined as those individuals who have completed their initial treatment and have no evidence of disease. In the case of breast cancer survivors, follow-up involves not only surveillance of locoregional and distant relapse, as well as screening for second primary breast cancers, but also evaluation of the effects related to the therapies received. Nowadays, there is controversy about what should be the method, the frequency, the duration and the type of health personnel that carry out the follow-up of these patients. The guides of the different scientific societies show a significant variability in the recommendations in this regard. This document aims to review the best available evidence on procedures for the detection of locoregional relapse, distant metastases, contralateral second breast cancer, and adverse events related to breast cancer treatments. Additionally, the percentages and sites of tumor recurrence are examined in relation to clinical stage and tumor biology

Objective: to describe clinical characteristics of patients with CF with ACFLD and mortality during follow-up. Method: Descriptive, retrospective study of patients with CF and ACFLD: FEVi < 40%, oxygen dependent, and/or referred to a lung transplantprogram. Clinical, microbiological, functional, genetic and mortality characteristics were collected. Results: Of 111 controlled patients, 39% met criteria for ACFLD. 52% were men and the mean age was 29,8 years- old. The average BMI was 19.9 kg/m2, 72% had pancreatic insufficiency and 87% had a genetic study, being the DF508 mutation the most frequent (67%). The average age of diagnosis was 11.2 years (SD ± 13 years), being in 54,5% over the age of 4 years. 75% had chronic Pseudomonas infection. 68% were oxygen dependent and 18% on noninvasive mechanical ventilation. In the last year of follow-up 70% had 2 or more hospitalizations. Of 27 patients who have been referred for transplantation, 7 underwent lung transplantation, 3 died waiting on the transplant list, 9 had contraindications: 4 due to malnutrition and 5 to poor adherence and poor support network. 32% (n = 14) of the ACFLD patients died, 93% due to respiratory causes. Conclusion: 39% of the patients had ACFLD. The average age for CF diagnosis was 11.2 years (SD ± 13 years) Barriers to entering the transplant list are: malnutrition, poor adherence, and lack of a support network. This is a population with a high mortality.

Efectos de un programa de rehabilitación remota en atención primaria en salud, posterior al alta hospitalaria por COVID-19: estudio observacional / Effects of a remote rehabilitation program in primary health care, after hospital discharge due to COVID-19: observational study

Se ha reportado un importante daño sistémico de los pacientes afectados por COVID-19, y aún existen interrogantes sobre las secuelas a largo plazo. Surge ante esto la necesidad de plantear programas de rehabilitación de los sistemas primarios de atención, que respondan a estas necesidades. Se realizó un programa de 6 semanas de rehabilitación remota, con seguimiento y progreso semanal, posterior al alta hospitalaria por COVID-19 a 114 usuarios de 4 centros de atención primaria de la comuna de El Bosque, Santiago, R. Metropolitana. Se incluyó a pacientes de edades entre 21 y 93 años, combinando los principios del ejercicio terapéutico individualizado, una evaluación presencial previo y posterior a las 6 semanas de trabajo. Los indicadores evaluados fueron: Minimental Abreviado, 1 Minute Sit to Stand Test (1min STST), Timed Up and Go (TUG), índice de Barthel y FRAIL. Se hicieron análisis inferenciales y descriptivos y se encontraron mejoras favorables en los indicadores de condición física (TUG y 1'STST), Índice de Barthel y el Simple "FRAIL" Questionnaire Screening Tool (FRAIL). En conclusión, si bien la mayoría de los indicadores tuvieron resultados favorables, es necesario seguir estudiando herramientas de evaluación más sensibles e intervenciones específicas que se adapten a las necesidades de las personas.

Significant systemic damage has been reported in patients affected by COVID-19, and questions remain about long-term sequelae. Therefore, the need arises to propose rehabilitation programs for primary care systems that respond to these needs. A 6-week program of remote rehabilitation, with weekly follow-up and progress, after hospital discharge for COVID-19 was carried out on 114 users from 4 primary care centers in the commune of El Bosque, Santiago, Chile. The program included patients from 21 to 93 years-old, combining the principles of individualized therapeutic exercise, a face-to-face evaluation before and after 6 weeks of work. The indicators evaluated were: Abbreviated Minimental, 1 minute Sit to Stand Test (1 min STST), Timed Up and Go (TUG), Barthel index and the Simple "FRAIL" Questionnaire Screening Tool (FRAIL). Inferential and descriptive analyses were carried out and favorable improvements were found in the indicators of physical condition (TUG and 1min STST), Barthel Index and FRAIL. In conclusion, while most of the indicators had favorable results, it is required to further explore more sensitive assessment tools and targeted interventions that are tailored to people's needs.

Resultados a largo plazo de la cirugía de revascularización coronaria según la presencia o no de enfermedad del tronco de la arteria coronaria izquierda / Long-term Outcomes of Coronary Artery Bypass Surgery According to the Presence or Absence of Left Main Coronary Artery Disease

RESUMEN Introducción: La cirugía de revascularización miocárdica (CRM) ha modificado la evolución natural de los pacientes con enfermedad de tronco de la arteria coronaria izquierda (TCI). En nuestro medio es escasa la información relacionada con el seguimiento a mediano y largo plazo de los pacientes intervenidos. Objetivo: Evaluar la implicancia de la enfermedad del TCI en la evolución alejada de los pacientes intervenidos con CRM, y conocer la mortalidad e incidencia de infarto de miocardio (IAM) y/o accidente cerebrovascular (ACV). Resultados: El seguimiento se completó en 438 pacientes (95,6%) con una mediana de 58 meses [Rango intercuartilo (RIC) 35-88 meses]. La sobrevida actuarial fue a 10 años del 91,8% para toda la población, sin diferencias significativas entre el grupo TCI (91,57%) vs. el grupo no TCI (91,86%), HR 1,008, IC95% 0,38-2,65, p=0,98. En el análisis multivariado se encontraron como predictores de mortalidad alejada la fracción de eyección ventricular izquierda preoperatoria (HR 0,95, IC 95% 0,93-0,97, p<0,001), la edad (HR 1,1, IC 95% 1,04-1,13, p< 0,001) y la prioridad no electiva de la cirugía (HR = 3,71; IC 95%: 1,3-10,35; p = 0,01). La sobrevida libre de IAM fue del 96,8% (TCI 94% vs. no TCI 97,4%, p= 0,8) y la libertad de ACV fue del 98% (TCI 97,8% vs. no TCI 98,1%, p= 0,8). Conclusión: En los pacientes sometidos a CRM, la presencia de enfermedad del TCI no incrementó la tasa de eventos duros (muerte, IAM y ACV) en el seguimiento alejado. Los resultados obtenidos en esta serie de pacientes son similares a los publicados en la bibliografía internacional utilizada para desarrollar las guías de revascularización miocárdica.

ABSTRACT Background: Coronary artery bypass grafting (CABG) has modified the natural evolution of patients with left main coronary artery (LMCA) disease. There is little information in our setting regarding the mid- and long-term follow-up of operated patients. Objective: The aim of this study was to evaluate the implication of LMCA disease in the long-term evolution of patients operated on with CABG, and to assess the mortality and incidence of myocardial infarction (AMI) and/or stroke. Results: Follow-up was completed in 438 patients (95.6%) with a median of 58 months [interquartile range (IQR) 35-88 months]. Actuarial survival at 10 years was 91.8% for the entire population, with no significant differences between the LMCA group (91.57%) vs. the non-LMCA group (91.86%), HR 1,008 95% CI 0.38-2.65, p=0.98. In multivariate analysis, preoperative left ventricular ejection fraction (HR = 0.95; 95% CI 0.93-0.97; p < 0.001), age (HR 1.1, 95% CI 1.04-1.13, p<0.001) and non-elective priority of surgery (HR=3.71; 95% CI 1.3-10.35; p=0.01) were independent predictors of long-term mortality. AMI-free survival was 96.8% (LMCA 94% vs. non-LMCA 97.4%, p=0.8) and freedom from stroke was 98% (LMCA 97.8% vs. non-LMCA 98.1 %, p=0.8). Conclusion: In patients undergoing CABG, the presence of LMCA disease did not increase the rate of hard events (death, AMI, and stroke) at the long-term follow-up. The results obtained in this series of patients are similar to those published in the international literature used to develop myocardial revascularization guidelines.

Method: a longitudinal retrospective series of cases conducted at the Pain Unit of the Hospital Universitario Son Llàtzer between 2018 and 2020. The study population consisted of 196 persons with that treatment. Basal measurement was conducted at one month, at three and six months. The following were measured: gender, age, time of evolution, applications conducted, improvement in intensity (NPRS scale: 0 to 10 points) and extent of pain, health-related quality of life (EQ-5D-3L: 0=the worst to 1=the best), patient global impression of improvement (PGI-I: improvement, worsening or no improvement), use of adjuvant drugs and side effects. Descriptive statistics was applied. Results: 133 patients were included with complete records(= 57 years; = 30.2 months of evolution; = 1.6 applications per person). There was a reduction in the pain area [Reduced (Month 1: 67%; Month 3: 41%; Month 6: 20%)] and pain intensity moved from = 7.35 to 6.32 at month six. Quality of life was superior to the mean baseline (0.37 of 1) in all measurements. There was improvement in PGI [Improvement (Month 1: 64.6%: Month 3: 58.9%; Month 6: 53.6 %)]. There was a reduction in the use of adjuvant medication [Reduced (Month 1: 28%; Month 3: 30%; Month 6: 67%)]. The adverse effects were pain (78.9%), erythema (67.7%) and itching (63.9%). Conclusion: the treatment applied by nurses was effective and safe. There must be follow-up at long term in order to detect any needs and changes.(AU)

Recuperación laboral clínica y funcional a 3 meses del alta en pacientes hospitalizados por neumonía por SARS-CoV-2: relación con la terapia recibida / Clinical and functional recovery and return to work 3 months after discharge in patients hospitalized for SARS-CoV-2 pneumonia: relationship with the therapy received

Resumen Introducción: La presentación clínica de neumonía por COVID-19 ha sido bien documentada; sin embargo, sus repercusiones a largo plazo son aún motivo de investigación. Objetivo: Evaluar la recuperación laboral, clínica y funcional respiratoria, a 3 meses del egreso de pacientes hospitalizados por neumonía por SARS-CoV-2, en relación con la terapia ventilatoria recibida. Pacientes y Métodos: Se analizó una cohorte prospectiva de 116 pacientes con neumonía por COVID-19 del Hospital Naval Almirante Nef de Viña del Mar, con seguimiento clínico y funcional respiratorio 3 meses después de su alta. Resultados: Mediana del seguimiento: 100 días. Constitución de la cohorte: 75 hombres, mediana de edad 60 años, 50% obesos, 34,5% fumadores y 13,8% con comorbilidad respiratoria. 16% recibió rehabilitación. Se reportó disnea en 48,3% y fatigabilidad en 33,6%. Solo 54,8% retornó al trabajo. El 65,2% que utilizó oxigenoterapia (O2) volvió a trabajar comparado con 44% que utilizó cánula nasal de alto flujo (CNAF) y 33,3% con ventilación mecánica invasiva (VMI). Mayoritariamente el grupo de O2 volvió a la vida normal en comparación con CNAF y VMI (71,4 versus 17,5% y 11,1% respectivamente). La función pulmonar fue normal en 39 pacientes (33,6%). La serie que volvió a vida normal tuvo mayor porcentaje de DLCO y test de caminata de 6 minutos normales. En comparación con la serie O2, la serie CNAF tuvo mayor frecuencia de alteración de DLCO (OR = 5) seguido por la serie VMI (OR = 3,6). Conclusión: A 3 meses de seguimiento, se evidenció ausentismo laboral, persistencia de síntomas y alteración funcional respiratoria (DLCO), especialmente en quienes recibieron soporte ventilatorio adicional a oxigenoterapia.

Introduction: The clinical presentation of COVID-19 pneumonia has been well documented; however, its long-term repercussions are still a matter of investigation. Objective: to evaluate the occupational, clinical and functional respiratory recovery, 3 months after the discharge of patients hospitalized for SARS-CoV-2 pneumonia, in relation to the ventilatory therapy received. Patients and Methods: A prospective cohort of 116 patients with COVID-19 pneumonia from Hospital Naval Almirante Nef (Viña del Mar, Chile) was analyzed, with clinical and functional respiratory follow-up at 3 months after being discharged. Results: Median follow-up: 100 days. Composition of the cohort: 75 men, median age 60 years-old, 50% obese, 34.5% smokers and 13.8% with respiratory comorbidity. 16% received rehabilitation. Dyspnea was reported in 48.3% and fatigue in 33.6%. Only 54.8% returned to work. 65.2% who used oxygen therapy (O2) returned to work compared to 44% who used high-flow nasal cannula (HFNC) and 33.3% with invasive mechanical ventilation (IMV). Mostly the O2 group returned to normal life compared to HFNC and VMI (71.4 versus 17.5% and 11.1% respectively). Lung function was normal in 39 patients (33.6%). The series that returned to normal life had higher percentage of normal DLCO and six-minute walk test. Compared to the O2 series, the CNAF series had a higher frequency of DLCO alteration (OR = 5) followed by the VMI series (OR = 3.6). Conclusion: At 3 months of follow-up, absenteeism from work, persistence of symptoms and respiratory functional alteration (DLCO) were evident, especially in those who received ventilatory support in addition to oxygen therapy.

Implante alto de las válvulas autoexpandibles con la técnica de "Cusp-Overlap", una estrategia para disminuir la necesidad de marcapasos en el implante percutáneo de válvula aórtica. Evolución a 30 días / High Self-expandable Valve Implantation with the Cusp-Overlap Technique, a Strategy to Reduce the Need for Pacemaker in Transcatheter Aortic Valve Implantation. 30-day Outcome

RESUMEN Objetivo: Analizar si el implante más alto en el implante percutáneo de válvula aórtica (TAVI) con válvulas auto-expandibles utilizando la superposición de las cúspides derecha e izquierda disminuye la necesidad de marcapasos definitivo. Material y Métodos: Se analizaron 164 pacientes consecutivos que recibieron TAVI con válvulas auto- expandibles; en 101(61,6%) de ellos se implantaron utilizando la vista coplanar de las tres cúspides, a la cual llamamos técnica convencional (CON) y en 63 (38,4%) utilizamos la técnica COVL, con superposición de las cúspides derecha e izquierda . El punto final primario (PFP) fue la necesidad de marcapasos definitivo (MCPD) a 30 días. Resultado: No hubo diferencias entre los grupos en la edad media, prevalencia de sexo masculino, hipertensión, cirugía de revascularización previa, antecedente de accidente cerebrovascular (ACV), función renal, o hemodiálisis. Los pacientes en el grupo COVL tuvieron más diabetes, angioplastia coronaria (ATC) e infarto previos. La ATC pre-TAVI fue similar, con mayor score STS (6,3 ± 2,1 vs. 5,8 ± 2,4; p = 0,05). La presencia de fibrilación auricular fue mayor en el grupo COVL sin diferencia en bloqueo auriculoventricular, de rama derecha o izquierda. No hubo diferencia en el área valvular aórtica, gradiente medio y fracción de eyección ventricular izquierda. A 30 días se observó una reducción significativa del PFP en la estrategia COVL, (6,3% vs 17,8%, p = 0,03). No hubo diferencia en mortalidad, ACV, sangrado mayor, infarto agudo de miocardio o regurgitación aórtica. Hubo tendencia a menor presencia de nuevo bloqueo competo de rama izquierda en el grupo COVL (4,8% vs. 12,9%, p = 0,08). Conclusiones: El uso de la técnica de COVL, que permite un implante más alto en el TAVI con válvulas autoexpandibles, demostró en esta serie ser factible y seguro, con disminución de la necesidad de MCPD sin aumento de las complicaciones.

ABSTRACT Objective: The aim of this study was to analyze whether higher transcatheter aortic valve implantation with self-expandable valves using the right and left cusp overlap strategy decreases the need for permanent pacemaker. Methods: A total of 164 consecutive patients undergoing TAVI with self-expandable valves were analyzed: 101 (61.6%) implanted with the conventional technique (CON) using the three-cusp coplanar view, and 63 (38.4%) using the right and left cusp overlap (COVL) technique. The primary endpoint (PEP) was the need for permanent pacemaker (PPM) at 30 days. Results: Mean age, prevalence of male gender, hypertension, prior coronary artery bypass graft surgery (CABG), and history of stroke, kidney function or hemodialysis was not different between groups. Patients in the COVL group had more diabetes, coronary percutaneous transluminal coronary angioplasty (PTCA) and prior infarct, and pre-TAVI PTCA was similar, with higher STS score (6.3±2.2 vs. 5.8±2.4; p=0.05). The presence of atrial fibrillation was greater in the COVL group, without differences in right or left bundle branch or atrioventricular block. There was no difference in aortic valve area, mean gradient and left ventricular ejection fraction. At 30 days, the need of PPM was significantly reduced with the COVL technique (6.3%% vs. 17.8%; p=0.03). No difference was observed in mortality, stroke, major bleeding, acute myocardial infarction or aortic regurgitation, and the presence of new-onset complete left bundle branch block was lower in the COVL group (4.8% vs. 12.9%; p=0.08). Conclusions: Use of the COVL technique, which allows higher self-expandable valve implantation during TAVI, was feasible and safe, decreasing the need for PPM without increasing complications.

Lipoatrofia semicircular: estudio y seguimiento clínico de 76 casos en Madrid, España. Propuesta de clasificación / Lipoatrophia semicircularis: Clinical study and follow-up of 76 cases in Madrid, Spain. Classification proposal

Introducción: La lipoatrofia semicircular (LS) puede tener presentaciones clínicas variadas, sin criterios diagnósticos claros. Se han propuesto varios factores etiopatogénicos, incluyendo determinados ambientes laborales. En este manuscrito se pretende describir las características de un brote de casos sospechosos de LS que se inició en mayo de 2008 entre trabajadores del Ayuntamiento de Madrid. Con base en la experiencia acumulada, se describen las acciones realizadas por el Servicio de Salud Laboral y se proponen unos criterios clínicos con implicación pronóstica que permitan categorizar los casos. Material y método: Estudio observacional retrospectivo tipo serie de casos que incluye datos recogidos de forma prospectiva de los pacientes revisados en el Servicio de ITS/Dermatología del Ayuntamiento Madrid entre 2008 y 2021. Se lleva a cabo la descripción de las medidas realizadas desde Salud Laboral. A través del registro y análisis estadístico de las variables recogidas durante la evaluación clínica de los pacientes, se proponen unos patrones clínicos definidos. Resultados: Se estudiaron 75 mujeres y un hombre, seguidas en su mayoría durante un período con mediana de 37 meses. Los síntomas locales fueron poco frecuentes (14,5%). Se propone la clasificación de las pacientes en 4 grupos: LS típica, LS unilateral, lipoatrofia en banda en miembros inferiores y lipoatrofia inespecífica. Al comparar los 2 primeros grupos con los 2 últimos, pudo constatarse una evolución clínica más favorable (76 versus 25,8% de mejoría total o parcial de las lesiones), además de una asociación negativa con la presencia de hipertrofia del tejido subcutáneo (p<0,001). Discusión: La LS típica (que puede ser frecuentemente unilateral) tiene por lo general una evolución favorable y unas características definidas que permiten diferenciarla de otros cuadros de lipoatrofia. Las medidas descritas realizadas por el Servicio de Salud Laboral contribuyeron a dicha evolución (AU)

Introduction: The clinical presentations of Lipoatrophia semicircularis (LS) vary, and diagnostic criteria are unclear. Several etiopathogenic factors, including occupational environmental ones, have been suggested. We aimed to describe a cluster of cases of suspected LS that started to appear in May 2008 among employees of the city council of Madrid, Spain. We report the actions taken by the council's Occupational Health Service and propose clinical categories with prognostic implications. Material and method: Retrospective observational case series study including prospectively collected data from patients evaluated between 2008 and 2021 at the Madrid City Council STI/Dermatology Department. Information on measures taken by the Occupational Health Service is detailed. The recording of clinical variables for statistical analysis and the proposal of defined clinical patterns were carried out. Results: We studied the cases of 75 women and one man, most of whom attended follow-up visits for a median of 37 months. Local symptoms were observed in just 14.5% of patients. The cases were classified into 4 groups: typical LS, unilateral LS, band-like lipoatrophy in the lower limbs, and nonspecific LS. Clinical outcomes were more often favorable in the first 2 groups, in which 76% of patients achieved total or partial improvement of lesions (vs. 25.8% in the last 2 groups). LS was negatively associated with the presence of hypertrophic subcutaneous adipose tissue (P<.001). Discussion: Typical LS, which can often be unilateral, generally has a satisfactory outcome. The clinical characteristics of this form distinguish it from other types of lipoatrophy. Measures taken by the Occupational Health Service contributed to favorable outcomes. In this series, LS was not associated with marked subcutaneous adipose tissue hypertrophy in the thighs (AU)
