Association between nutritional risk status and both diaphragmatic dysfunction and diaphragm atrophy in medical intensive care unit patients.

Introduction: Aim: critical illness often leads to malnutrition and diaphragmatic dysfunction (DD), common in intensive care units (ICU). Ultrasonography (US) is a potent tool for detecting DD. This study examines the connection between malnutrition risk and DD in ICU patients using ultrasonographic diaphragm measurements in medical ICU patients. Methods: we assessed nutritional risk using risk screening tools and mid-upper arm circumference measurements (MUAC). Diaphragm atrophy (DA) and DD were evaluated by measuring diaphragmatic excursion (DE), thickness, and thickening fraction (TF) by US. We then compared these diaphragmatic measurements in patients based on their nutritional risk scores. Results: of the fifty patients studied, 54 % to 78 % were at risk of malnutrition, 28 % exhibited diaphragm atrophy (DA), and 24 % showed DD upon ICU admission. Malnutrition risk diagnosed by all nutritional risk screening tools was significantly more frequent in patients with DD, while diagnosed by MUAC was considerably higher in patients with DA. A total of 16 patients (32 %) died during their ICU stay, with DD, DA, and malnutrition risks (as identified by the mNUTRIC Score) being more prevalent among non-survivors (p < 0.05). Malnutrition risk (as determined by the mNUTRIC Score) was an independent risk factor for DD [OR (95 % CI): 6.6 (1.3-34), p = 0.03]. Conclusion: malnutrition risk may be significantly associated with DD and DA in medical ICU patients upon ICU admission.

Introducción: Objetivo: las enfermedades graves a menudo conducen a desnutrición y disfunción diafragmática (DD), comunes en las unidades de cuidados intensivos (UCI). La ultrasonografía (US) es una herramienta poderosa para detectar la DD. Este estudio examina la conexión entre riesgo de desnutrición y DD en pacientes de UCI utilizando mediciones ultrasonográficas del diafragma. Métodos: evaluamos el riesgo nutricional utilizando herramientas de evaluación de riesgos y mediciones de la circunferencia del brazo en su punto medio superior (MUAC). La atrofia del diafragma (DA) y la DD se evaluaron midiendo la excursión diafragmática (DE), el grosor y la fracción de engrosamiento (TF) por ecografía. Luego, comparamos estas mediciones diafragmáticas en pacientes según sus puntuaciones de riesgo nutricional. Resultados: de los cincuenta pacientes estudiados, entre el 54 % y el 78 % estaban en riesgo de desnutrición, el 28 % presentaban atrofia del diafragma (DA) y el 24 % mostraban DD al ingreso en la UCI. El riesgo de desnutrición diagnosticado por todas las herramientas de evaluación del riesgo nutricional fue significativamente más frecuente en los pacientes con DD, mientras que el diagnosticado por el MUAC fue considerablemente mayor en los pacientes con DA. Un total de 16 pacientes (32 %) fallecieron durante su estancia en la UCI, siendo la DD, la DA y los riesgos de desnutrición (según lo identificado por la puntuación mNUTRIC) más prevalentes entre los no sobrevivientes (p < 0,05). El riesgo de desnutrición (según lo determinado por la puntuación mNUTRIC) fue un factor de riesgo independiente de la DD [OR (95 % CI): 6,6 (1,3-34), p = 0,03]. Conclusión: en este estudio se encontró una asociación significativa entre el riesgo de desnutrición y la disfunción diafragmática, así como con la atrofia diafragmática al ingreso en la UCI.

The Impact of CoronaVac Vaccination on 28-day Mortality Rate of Critically Ill Patients with COVID-19 in Türkiye.

Background: Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear. Aims: To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19. Study Design: Multicenter prospective observational clinical study. Methods: This study was conducted in 60 hospitals with ICUs managing critically ill patients with COVID-19. Patients aged ≥ 18 years with confirmed COVID-19 who were admitted to the ICU were included. The present study had two phases. The first phase was designed as a one-day point prevalence study, and demographic and clinical findings were evaluated. In the second phase, the 28-day mortality was evaluated. Results: As of August 11, 2021, 921 patients were enrolled in the study. The mean age of the patients was 65.42 ± 16.74 years, and 48.6% (n = 448) were female. Among the critically ill patients with COVID-19, 52.6% (n = 484) were unvaccinated, 7.7% (n = 71) were incompletely vaccinated, and 39.8% (n = 366) were fully vaccinated. A subgroup analysis of 817 patients who were unvaccinated (n = 484) or who had received two doses of the CoronaVac vaccine (n = 333) was performed. The 28-day mortality rate was 56.8% (n = 275) and 57.4% (n = 191) in the unvaccinated and two-dose CoronaVac groups, respectively. The 28-day mortality was associated with age, hypertension, the number of comorbidities, type of respiratory support, and APACHE II and sequential organ failure assessment scores (p < 0.05). The odds ratio for the 28-day mortality among those who had received two doses of CoronaVac was 0.591 (95% confidence interval: 0.413-0.848) (p = 0.004). Conclusion: Vaccination with at least two doses of CoronaVac within six months significantly decreased mortality in vaccinated patients than in unvaccinated patients.
