Los iSGLT2 en la insuficiencia cardiaca. ¿Sus beneficios pueden extenderse a todo el espectro de la fracción de eyección? / SGLT2i in heart failure: can their benefits be expanded across the entire spectrum of ejection fraction?

La publicación del estudio EMPEROR-Preserved y la extensión del beneficio cardiovascular de los inhibidores del cotransportador de sodio-glucosa tipo 2 (iSGLT2) a pacientes con insuficiencia cardiaca IC y fracción de eyección (FE)> 40% supone un importante hito en el tratamiento de la IC con FE conservada (IC-FEc). A raíz de estos resultados, en febrero de 2022 la Food and Drug Administration estadounidense aprobó el uso de la empagliflozina para el tratamiento de pacientes con IC independientemente de la FE. Sin embargo, un análisis más detallado del estudio EMPEROR-Preserved genera ciertas dudas en relación con la banda de FE más alta (> 60%). Este grupo de pacientes presenta una gran heterogeneidad y probablemente no se pueda considerar un único fenotipo para fines terapéuticos y de abordaje clínico. Además, la FE es un parámetro continuo. Por ello, no parece que una diferenciación basada en puntos de corte matemáticos concuerde con la evidencia más reciente, que apunta precisamente a un cambio más gradual en cuanto a mecanismos subyacentes, etiologías y respuesta al tratamiento a lo largo del espectro de la FE. Un mejor conocimiento de los mecanismos fisiopatológicos es fundamental para establecer nuevas dianas terapéuticas, interpretar los resultados de los ensayos clínicos y desarrollar tratamientos dirigidos y eficaces (AU)

The publication of the EMPEROR-Preserved trial and data on the benefits of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with heart failure (HF) with ejection fraction (EF)> 40% represent a significant step forward in the treatment of HF with preserved EF. Given these results, in February 2022 the US Food and Drug Administration approved the use of empaglifozin in adults with HF with reduced or preserved EF. However, more detailed analysis of the EMPEROR-Preserved trial led to doubts about the effect of empagliflozin in patients with an EF of> 60% this patient group is widely heterogeneous and, probably, a single phenotype cannot be considered in treatment goals or the clinical approach. Moreover, EF occurs on a continuum and classifications of HF according to arbitrary cut-points in EF do not appear consistent with recent evidence, which points to a gradual shift and considerable overlap in underlying mechanisms, phenotypes and treatment response over the spectrum of EF. Enhanced knowledge of pathophysiological mechanisms is essential to establish new therapeutic targets, interpret the results of clinical trials, and develop targeted and effective therapies (AU)

Airway management of COVID-19 patients: A survey on the experience of 1125 physicians in Spain.

BACKGROUND: We explored the experience of clinicians from the Spanish Society of Anesthesiology (SEDAR) in airway management of COVID-19 patients. METHODS: An software-based survey including a 32-item questionnaire was conducted from April 18 to May 17, 2020. Participants who have been involved in tracheal intubations in patients with suspected or confirmed COVID-19 infection were included anonymously after obtaining their informed consent. The primary outcome was the preferred airway device for tracheal intubation. Secondary outcomes included the variations in clinical practice including the preferred video laryngoscope, plans for difficult airway management, and personal protective equipment. RESULTS: 1125 physicians completed the questionnaire with a response rate of 40,9%. Most participants worked in public hospitals and were anesthesiologists. The preferred device for intubation was the video laryngoscope (5.1/6), with the type of device in decreasing order as follows: Glidescope, C-MAC, Airtraq, McGrath and King Vision. The most frequently used device for intubation was the video laryngoscope (70,5%), using them in descending order as follow: the Airtraq, C-MAC, Glidescope, McGrath and King Vision. Discomfort of intubating wearing personal protective equipment and the frequency of breaching a security step was statistically significant, increasing the risk of cross infection between patients and healthcare workers. The opinion of senior doctors differed from younger physicians in the type of video-laryngoscope used, the number of experts involved in tracheal intubation and the reason that caused more stress during the airway management. CONCLUSIONS: Most physicians preferred using a video-laryngoscope with remote monitor and disposable Macintosh blade, using the Frova guide.

Analysis of Candida auris candidemia cases in an Intensive Care Unit of a tertiary hospital.

Candida auris is a multi-resistant emerging fungus. OBJECTIVES: To analyze the relationship between colonization by C. auris and the appearance of invasive candidiasis. Description of the sample of colonized patients, risk factors for colonization and/or infection, and calculation of mortality rates. METHODOLOGY: Longitudinal observational study in an anesthesia intensive care unit in 2018. RESULTS: 2130 patients were admitted. Surveillance studies were positive in 124 patients; 118 cases involved skin colonization and 52 were pharyngeal. Patients with a positive blood culture were identified. A statistically significant association was found between pharyngeal colonization and the appearance of a positive blood culture. There were significant differences between patients with a high Candida Score as a risk factor for candidemia. In total, 67% of pharyngeal carriers negativized at 1 month compared to 21% of cutaneous carriers, who negativized after 3-4 months. Of the patients with positive blood cultures, 70% of non-survivors received only monotherapy, although this difference was not statistically significant due to the small sample size. CONCLUSIONS: The incidence of C. auris, a multi-resistant pathogen that is difficult to diagnose, treat and eradicate, is steadily increasing among critically ill patients. Its status as an emerging threat to global health calls for the urgent implementation of early in-hospital detection systems.

Intubation in two patients with difficult airway management and tracheal stenosis after tracheostomy in thoracic surgery. / Intubación en dos pacientes con vía aérea difícil y estenosis traqueal tras traqueostomía en cirugía torácica.

Lung isolation in thoracic surgery is a challenge, this is even more complex in the presence of unknown tracheal stenosis (TS). We report two cases of unknown TS and its airway management. TS appears most frequently after long term intubation close to the endotracheal tube cuff or in the stoma of tracheostomy that appears as a consequence of the granulation tissue after the surgical opening of the trachea. Clinical history, physical examination, difficult intubating predictors and imaging tests (CT scans) are crucial, however most of tracheal stenosis may be unnoticed and symptoms depend on the degree of obstruction. In our cases, the patients presented anatomical changes due to surgery and previous tracheostomy that led to a TS without symptoms. There is scarce literature about the intubation in patients with previous tracheostomy in thoracic surgery. In the first case, a Univent® tube was used using a flexible fiberscope but an acute tracheal hemorrhage occurred. In the second case, after intubation with VivaSight SL® in an awake patient, the insertion of a bronchial blocker was performed through an endotracheal tube guided by its integrated camera without using flexible fiberscopy.

Angiosarcoma epitelioide vertebral primario / Primary spinal epitheliod angiosarcoma

El angiosarcoma óseo primario es una rara eventualidad que representa, tan solo, el 1% de todos los angiosarcomas. Estos tumores asientan con mayor frecuencia en huesos largos. La afectación vertebral primaria se ha comunicado en un 10% de angiosarcomas. Como resultado de esta rareza se desconocen, en gran medida, sus características patológicas, clínicas y terapéuticas. Presentamos el caso de una paciente con angiosarcoma epitelioide vertebral primario en D8 que debutó con dolor dorsal y paraparesia con el objetivo de intentar contribuir a un mejor conocimiento de este raro proceso (AU)

Primary bone angiosarcoma is rare, and is only seen in 1% of all sarcomas. These tumours are more often found in the long bones. Primary spinal involvement has been reported in 10% of angiosarcomas. As a result of its rarity, its pathological, clinical and therapeutic characterists are largely unknown. We presnt the case of a patient with a primary vertebral epithelioid angiosarcoma in D8 which initially presented as dorsal pain and paraparesis, with the aim of contributing to a better knowlwedge of this rare process (AU)

Experiencia con un formato simplificado de la herramienta de ayuda en la toma de decisiones Adjuvant Online en pacientes con cáncer de mama / Experience with a simplified format of decision making tool adjuvant Online in breast cancer patients

Fundamento. Adjuvant. Online calcula el riesgo de recidiva y muerte a 10 años y proporciona estimaciones del beneficio del tratamiento adyuvante en pacientes con cáncer de mama. Testamos su aplicabilidad y analizamos únicamente estimaciones de mortalidad. Método. Presentamos las estimaciones de 66 pacientes intervenidas de cáncer de mama unilateral y unicéntrico, sin enfermedad residual ni metástasis. Las variables analizadas fueron edad, comorbilidad, receptores de estrógenos, grado histológico, tamaño tumoral, ganglios metastásicos, tipo de tratamiento hormonal y de quimioterapia. Resultados. La estimación de la mediana de supervivencia fue del 77%, de mortalidad por cáncer fue del 18% y por otras causas fue del 5%. La media de reducción absoluta del riesgo (RAR) de mortalidad con tratamiento hormonal fue del 4%, con quimioterapia fue del 4,5% y con tratamiento combinado fue del 7%. Resultados. Todas las pacientes con algún beneficio decidieron recibir tratamiento hormonal. Cuarenta y tres pacientes (65%) decidieron recibir quimioterapia y 23 pacientes (35%) decidieron no recibirla. La media de reducción del riesgo con quimioterapia fue del 2% en quien decidió no recibir quimioterapia y fue del 8% en quien decidió recibirla. Existe asociación entre la decisión de quimioterapia y la estimación del riesgo de mortalidad por cáncer (p=0,0001), del riesgo de mortalidad por otras causas (p=0,038) y de la RAR (p=0,0001). El 6% de las pacientes con RAR del 1%, el 50% de las que tenían RAR entre el 2–5%, y el 61,8% con RAR entre el 6–10% eligieron la quimioterapia. Conclusiones. Todas las mujeres optan por el tratamiento hormonal independientemente del beneficio. Las razones para elegir la quimioterapia fueron el propio pronóstico vital y la magnitud del beneficio. Algunas pacientes deciden elegir quimioterapia con beneficios mínimos(AU)

Background. Adjuvant. Online estimates 10-year recurrence and mortality outcomes for breast cancer patients and predicts the effect of each type of treatment. Our purpose was to test the applicability by only analysing mortality estimations. Method. We present estimations of 66 women with definitive surgery and axillary staging for unilateral, unicentric, invasive adenocarcinoma, without metastatic or residual disease. Age, co-morbidity, estrogen receptor status, histological grade, tumor size, number of positive nodes, and hormone therapy or chemotherapy option, were the variables required. Results. Median of survival estimations was 77%, cancer mortality 18% and mortality for other reasons 5%. The average of absolute risk reduction (ARR) with hormone therapy was 4%, with chemotherapy 4.5% and with combined treatment 7%. Results. All the patients with some benefit decided to receive hormone therapy. Forty-three patients (65%) decided to receive chemotherapy and 23 (35%) did not. The average risk reduction with chemotherapy was 2% in those who decided not to receive chemotherapy and 8% in those who decided to receive it. There was an association between a chemotherapy decision and the estimation of the risk of breast cancer mortality (P=0.0001), risk of mortality for other reasons (P=0.038), and the ARR (P=0.0001). There were 6% of the patients with an ARR of 1%, 50% between 2–5% and 61.8% between 6–10%, who chose chemotherapy. Conclusions. All women opted for hormone therapy regardless of benefit. The reasons for choosing chemotherapy were the prognosis itself and the magnitude of benefit. Some patients decided to choose chemotherapy even when the benefit was minimal(AU)
