ERS International Congress 2022: highlights from the Respiratory Intensive Care Assembly.

Early Career Members of Assembly 2 (Respiratory Intensive Care) attended the 2022 European Respiratory Society (ERS) International Congress in Barcelona, Spain. The conference covered acute and chronic respiratory failure. Sessions of interest to our Assembly members and to those interested in respiratory critical care included the state-of-the-art session on respiratory critical care, the journal session (ERS/Lancet) on acute respiratory distress syndrome (ARDS) phenotyping into precision medicine, and sessions on specificity of coronavirus disease 2019 ARDS and its post-critical care. A symposium on treatment of acute respiratory failure in patients with COPD and innovations in mechanical ventilation either in the intensive care unit or at home were also reported upon. These sessions are summarised in this article.

Frequency of use and preferences for information and communication technologies in patients with sleep apnea: A multicenter, multinational, observational cross-sectional survey study.

BACKGROUND: Obstructive sleep apnea (OSA) is a condition characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep. An accessible method to facilitate self-management education is through information and communication technologies (ICTs). PURPOSE: To assess the frequency of and preferences for ICT use in patients with sleep apnea. METHODS: A multicenter, multinational, observational cross-sectional survey study was conducted between 2018 and 2019 in sleep units in different countries of Latin America, including patients of both genders older than 18 years with a diagnosis of sleep apnea. Participants were asked to complete 20 questions in a self-administered survey about the frequency of use of ICTs and their preferences for receiving disease-related information. RESULTS: A total of 435 patients participated in the study, with a mean age of 59.1 ± 14.0; 62.5% (n = 272) were males. Most patients had access to cellphones (92.4%, n = 402), smartphone (83.0%, n = 361) and an internet connection (82.3%, n = 358). One-to-one ICTs were regarded as the most frequently used ICT type, as 75.4% (n = 328) of participants reported using them daily (χ2(4) = 848.207, p =.000). With respect to categories of interest, one-to-one ICTs were also the best rated ICT type to receive (59.1%, n = 257; χ2(2) = 137.710, p =.000) and ask physicians (57.0%, n = 248; χ2(2) = 129.145, p =.000) information about OSA. Finally, older adults and those with lower educational levels were found to be less likely to use and be interested in ICTs. CONCLUSION: Most patients have access to different ICTs and often use them to seek and receive medical information. The preferred ICTs include those in the one-to-one category (WhatsApp, email) and the one-to-many category (web browsers) for general health and OSA-related information.

Evaluación respiratoria y manejo de pacientes con obesidad candidatos a procedimientos quirúrgicos y cirugía bariátrica / Respiratory evaluation and management of obese patients who are candidates for surgical procedures and bariatric surgery

En el seno de la Sección de Sueño, Oxigenoterapia y Asistencia Ventilatoria de la Asociación Argentina de Medicina Respiratoria, se planteó el desarrollo de sugerencias para la exploración respiratoria del paciente con obesidad y definiciones sobre el manejo perioperatorio en cirugía bariátrica y procedimientos quirúrgicos electivos (cirugía no bariátrica). Esta iniciativa se basó en la necesidad de contar con lineamientos adaptados a la realidad local y discutida por expertos que se desempeñan en la realidad coyuntural cotidiana de nuestro país. La agenda se inició en agosto de 2020 en un grupo de revisión de la bibliografía y redacción. Revisores de diferentes provincias argentinas efectuaron una extensa valoración de la evidencia. Luego, un comité editorial realizo una revisión crítica del documento. Finalmente, todo el grupo debatió las sugerencias que se exponen como puntos clave. Este documento exhorta a cirujanos y clínicos a trabajar junto a especialistas respiratorios en la evaluación del riesgo, definición de la aptitud operatoria y corrección de trastornos funcionales y apneas del sueño. La cirugía en individuos con obesidad y la cirugía bariátrica, son procedimientos a los que se arriba luego de una evaluación exhaustiva de la situación clínica y funcional. La tarea multidisciplinaria y el tratamiento de las anormalidades detectadas pueden disminuir los riesgos perioperatorios. Pacientes con obesidad que requieren cirugía electiva con anestesia general deben ser evaluados mediante pruebas objetivas para confirmar la presencia de apneas del sueño y estar adecuadamente tratados con CPAP.

Within the Sleep, Oxygen Therapy and Ventilatory Assistance Section of the Argentine Association of Respiratory Medicine, we de velopment of recommendations for the respiratory exploration of patients with obesity and definitions on perioperative management in bariatric surgery and elective surgical procedures (surgery non bariatric). This initiative was based on the need to have guidelines adapted to the local reality and discussed by experts who work in the daily conjunctural reality of our country. The schedule was started in August 2020 in a literature review group. Reviewers from different Argentine provinces carried out an extensive assessment of the evidence. Then, an editorial committee performed a critical review of the document. Finally, the whole group discussed the suggestions that are presented as key points. This document encourages surgeons and clinicians to work close to respiratory specialists in assessing risk, defining operative competence, and revise functional disorders and sleep apnea. Surgery in obese individuals and bariatric surgery are procedures that are reached after a detailed evaluation about clinical and functional situation. The multidisciplinary team and the treatment of detected abnormalities can reduce perioperative risks. Obese patients who require elective surgery with general anesthesia should be evaluated by objective tests to confirm the presence of sleep apnea and be adequately treated with CPAP.

Tratamiento con presión positiva de la Apnea Obstructiva del Sueño. Posición de la Asociación Argentina de Medicina Respiratoria / Treatment of Obstructive Sleep Apnea with Positive Pressure. Position of the Argentinian Association of Respiratory Medicine

La Sección de Sueño, Oxigenoterapia y Otros Tratamientos Crónicos Domiciliarios, de la Asociación Argentina de Medicina Respiratoria (AAMR) se planteó desarrollar en nuestro país un documento formal que exponga la base científica y costo económica de la cobertura del tratamiento del síndrome de apneas e hipopneas obstructivas durante el sueño (SAHOS). Esta iniciativa se basó en la necesidad de analizar la visión de expertos locales que se desempeñan en la realidad coyuntural cotidiana de nuestro país, para elaborar un documento informativo para miembros del equipo de salud. A su vez, exhorta a los diferentes actores del sistema a determinar pautas claras que sirvan de referencia para la generación de políticas públicas. La agenda se inició en septiembre de 2018 en un grupo de redacción. Luego, revisores de cinco provincias argentinas efectuaron una extensa valoración de la evidencia publicada. Para la edición final se realizó una reunión presencial de discusión y generación de consenso. Se plantearon como objetivos; actualizar la base científica que define al SAHOS como problema de salud de proporciones epidémicas con consecuencias demostrables en la salud, analizar los datos de costo-efectividad del tratamiento con CPAP para las formas moderadas a severas y leves con síntomas y unificar conceptos en relación con la calidad mínima necesaria en los tratamientos que se ofrecen. Finalmente, se analiza la situación en la Argentina sobre la base a datos publicados y se presenta una propuesta de mejora en tres niveles: social y económico, logístico-administrativo y clínico

The Sleep, Oxygen Therapy and Other Home Chronic Treatments Section of the Argentinian Association of Respiratory Medicine (AAMR, for its acronym in Spanish) proposed the development in our country of a formal document exposing the scientific and cost-economical foundation of the coverage for the treatment of obstructive sleep apnea and hypopnea syndrome (OSAHS). This initiative was based on the need to analyze the vision of local experts who work in the daily current reality of our country, in order to create an informative document for the members of the medical staff. In turn, it encourages the different members of the system to determine clear guidelines that could be used as reference for generating public policies. The agenda began in September, 2018 within a writing staff. Then, editors from five Argentinian provinces made a thorough assessment of published evidence. For the final edition, a face-to-face meeting was arranged to discuss and reach a consensus. The suggested objectives were: to update the scientific base that defines the OSAHS as a health problem of epidemic proportions with health consequences; to analyze cost-efficacy data of CPAP treatment for moderate to severe and mild-with-symptoms forms of the disease and to unify concepts in relation to the minimum necessary quality of treatments to be offered. Finally, the situation in Argentina is analyzed basing on published data, and a proposal is presented for improvement in three levels: social and economic, logistic-administrative and clinical.

Decreased relative risk of pneumococcal pneumonia during the last decade, a nested case-control study.

BACKGROUND: Streptococcus pneumoniae (SP) is one of the most common pathogens of Community-Acquired Pneumonia (CAP), but recent reports suggest that its incidence may be declining in relation to the use of the conjugate 13-valent pneumococcal vaccine in children. We compared the result of the immunochromatographic SP urinary antigen test (SPUAT) and clinical outcomes in patients with CAP admitted in two periods of time: 2001-2002(CAP1) and 2015-2016(CAP2). METHODS: This was a matched nested case-control study of two prospectively recorded cohorts of patients admitted with CAP, with SPUAT and blood culture performed in all patients. CAP2 cases and CAP1 controls were matched for age ± 4 years, sex, and Pneumonia Severity Index (PSI) score ± 10 points. Odds ratios (OR) for having SPUAT positive was estimated by conditional logistic regression. A multivariate model assessed the contribution of individual variables. RESULTS: Four hundred ninety-eight patients were recruited; 307 during the CAP1 and 191 during the CAP2 periods. Comparing both periods we observed differences, in age, PSI score, and the percentage of smokers, outpatients, previously immunized with pneumococcal vaccine, and positive SPUAT. On the other hand, mortality, admission from nursing homes, pneumococcal bacteremia and hospital admission were not different. After matching, pneumonia due to SP per the SPUAT was observed in 34(23.4%) of CAP1 and in 12(8.3%) of CAP2 patients (p < 0.001), and 6/145 CAP1 vs 33/145 CAP2 patients had received pneumococcal immunization before their admission (p < 0.001). A multivariate analysis confirmed that, independent of falling into PSI class 5, having not received the pneumococcal vaccine and having not survived the episode of pneumonia, there were two factors that increased the probability of having SPUAT positive: developing pneumonia during the CAP1 period (OR = 1.23) and having pneumococcal bacteremia (OR = 2.66). CONCLUSION: We observed a reduction of the role of SP as pathogen, along with an increase in the number of patients who received pneumococcal immunization before admission, in 2015-2016 compared to 2001-2002. In addition, the use of conjugate 13-valent vaccine, starting in 2012 for childhood immunization, could be an additional factor contributing to these changes, as a result of early herd immunity in adults pneumonia.
