RESUMO
BACKGROUND: We aimed to evaluate the cardiac adverse events (AEs) in hospitalized patients with coronavirus disease 2019 (COVID-19) who received remdesivir plus standard of care (SoC) compared with SoC alone (control), as an association was noted in some cohort studies and disproportionality analyses of safety databases. METHODS: This post hoc safety analysis is based on data from the multicenter, randomized, open-label, controlled DisCoVeRy trial in hospitalized patients with COVID-19. Any first AE that occurred between randomization and day 29 in the modified intention-to-treat (mITT) population randomized to either remdesivir or control group was considered. Analysis was performed using Kaplan-Meier survival curves, and Kaplan-Meier estimates were calculated for event rates. RESULTS: Cardiac AEs were reported in 46 (11.2%) of 410 and 48 (11.3%) of 423 patients in the mITT population (n = 833) enrolled in the remdesivir and control groups, respectively. The difference between both groups was not significant (hazard ratio [HR], 1.0; 95% confidence interval [CI], .7-1.5; P = .98), even when serious and nonserious cardiac AEs were evaluated separately. The majority of reports in both groups were of arrhythmic nature (remdesivir, 84.8%; control, 83.3%) and were associated with a favorable outcome. There was no significant difference between the two groups in the occurrence of cardiac AE subclasses, including arrhythmic events (HR, 1.1; 95% CI, .7-1.7; P = .68). CONCLUSIONS: Remdesivir treatment was not associated with an increased risk of cardiac AEs compared with control in patients hospitalized with moderate or severe COVID-19. These results are consistent with other randomized, controlled trials and meta-analyses. Clinical Trials Registration. NCT04315948; EudraCT 2020-000936-23.

OBJECTIVES: Cardiac tamponade is a potentially life-threatening complication during extracorporeal membrane oxygenation (ECMO). In this study, the authors assessed the incidence, patient characteristics, and risk factors for mortality of cardiac tamponade during ECMO. DESIGN: The authors queried the Extracorporeal Life Support Organization (ELSO) Registry from 1997 to 2021 for all adults with cardiac tamponade as a reported complication during ECMO. PARTICIPANTS: Cardiac tamponade was reported in 2,176 (64% men; 53.8 ± 0.33 years) of 84,430 adults (2.6%). MEASUREMENTS AND MAIN RESULTS: Venoarterial ECMO was the main configuration (78%), followed by venovenous ECMO (VV ECMO) (18%), for cardiac (67%), pulmonary (21%) support, and extracorporeal cardiopulmonary resuscitation (ECPR) (12%). Percutaneous cannulation was performed in 51%, with the femoral vein and femoral artery as the most common sites for drainage and return cannulae, with dual-lumen cannulae in 39% of VV ECMO. Hospital survival was lower (35% v 49%; p < 0.01) when compared with that of all adults from the ELSO Registry. In multivariate analysis, age, aortic dissection and/or rupture, COVID-19, ECPR, pre-ECMO renal-replacement therapy, and prone position are associated with hospital mortality, whereas ECMO for pulmonary support is associated with hospital survival. Similarly, renal, cardiovascular, metabolic, neurologic, and pulmonary complications occurred more frequently in nonsurvivors. CONCLUSIONS: Cardiac tamponade is a rare complication during ECMO that, despite being potentially reversible, is associated with high hospital mortality. Venoarterial ECMO is the most common configuration. ECMO for pulmonary support was associated with higher survival, and ECPR was associated with higher mortality. In these patients, other ECMO-related complications were frequently reported and associated with hospital mortality.

Background: Thousands of people suffer from anxiety, depression, and insomnia every day, with benzodiazepines being one of the strategies used to treat these conditions. Withdrawal from its long-term use can lead to potentially life-threatening complications, including Takotsubo syndrome. The authors highlight an atypical case of Takotsubo syndrome secondary to benzodiazepine withdrawal, a rare life-threatening complication of acute substance withdrawal. Case summary: A 58-year-old female presented to the emergency department with altered mental status and acute pulmonary oedema after discontinuing her prescribed benzodiazepines 3 days prior to presentation. Electrocardiogram (ECG) demonstrated anterior ST-segment elevation, with Q-wave and T-wave inversion with prolonged QT interval. Troponin I concentration and B-type natriuretic peptide were elevated to 5407â ng/L (normal ≤ 16â ng/L) and to 1627.0â pg/L (normal ≤ 100â pg/mL), respectively. Echocardiogram showed ballooning of the left ventricle (LV) apex with dyskinesia of the mid and apical segments, with LV function of 15%. Coronary angiography was normal, but left ventriculography showed severe LV systolic dysfunction with akinesis of the mid and apical LV segments and hyperdynamic basal segments. A presumptive diagnosis of benzodiazepine withdrawal-induced Takotsubo syndrome was made, and patients' symptoms, ECG findings, and LV dysfunction resolved after benzodiazepine administration. Six months post discharge, the patient remained asymptomatic with a normal biventricular function, and a beta-blocker was successfully introduced as part of a lifelong plan. Discussion: A diagnosis of benzodiazepine withdrawal-induced Takotsubo syndrome is an underrecognized and challenging diagnosis, due to its atypical clinical presentation. High degree of clinical suspicion for this syndrome is crucial, since favourable prognosis depends on prompt diagnosis and treatment.
RESUMO
Invasive pneumococcal disease is a serious infection with an elevated case-fatality rate that can be even higher among patients with asplenia. Its impact has been blunted by the widespread use of vaccines; even recently, in 2021, two new pneumococcal conjugate vaccines emerged. The authors present a case of a 58-year-old male, splenectomised with the immunisation schedule complete, who died of invasive pneumococcal disease with a fulminant course. It is highlighted that fever in a patient with impaired splenic function is an emergency, and despite the success of immunisation in reducing pneumococcal carriage and invasive disease, serotypes continue to change. Also, the local epidemiology may help guide situations where the immunisation recommendations are dubious regarding the implementation of the new vaccines.
RESUMO
BACKGROUND: Carbapenemase-producing Enterobacterales (CPE) is an increasing problem in healthcare settings. This study aimed to identify the source of a CPE outbreak that occurred in 2022, in a tertiary hospital in the North of Portugal, to identify exposed patients, and to assess the risk of becoming CPE-positive following hospital admission. METHODS: A multi-disciplinary investigation was conducted including descriptive, analytical, and molecular epidemiology, environmental screening, and assessment of infection control measures. Clinical and environmental isolates were analyzed using whole-genome sequencing and phylogenetic analysis. Additionally, a prospective observational cohort study was conducted to further investigate the risk factors associated with the emergence of new cases in cohorts of CPE-negative admitted patients. RESULTS: We observed the presence of multispecies KPC-, IMP-, and/or NDM-producing isolates. Genetically indistinguishable clinical and environmental isolates were found on the same room/ward. The ST45 KPC-3-producing Klebsiella pneumoniae clone was the responsible for the outbreak. During patients' treatment, we detected the emergence of resistance to ceftazidime-avibactam, associated with mutations in the blaKPC-3 gene (blaKPC-46, blaKPC-66 and blaKPC-124, the last variant never previously reported), suggesting a vertical evolutionary trajectory. Patients aged ≥ 75 years, hygiene/feeding-care dependent, and/or subjected to secretion aspiration were risk factors for CPE colonization after hospital admission. Additionally, cases with previous admission to the emergency department suggest that CPE dissemination may occur not only during hospitalization but also in the emergency department. CONCLUSION: Overall, the study highlights that selection pressure with antibiotics, like ceftazidime-avibactam, is a contributing factor to the emergence of new ß-lactamase variants and antibiotic resistance. It also shows that the hospital environment can be a significant source of CPE transmission, and that routine use of infection control measures and real-time molecular epidemiology investigations are essential to ensure the long-term termination of CPE outbreaks and prevent future resurgences.

Objectives: Despite the discrepancy between demand and availability of organs for transplantation, controlled circulatory death donation has not been implemented in Portugal. This study aimed to estimate the potential increase in organ donation from implementing such a program. Material and Methods: All deceased patients within the intensive care medicine department at Centro Hospitalar Universitário de São João, throughout the year 2019, were subjected to retrospective analysis. Potential gain was estimated comparing the results with the number of donors and organs collected during the same period at this hospital center. Differences in variables between groups were assessed using t tests for independent samples or Mann-Whitney U tests for continuous variables, and chi-squared tests were used for categorical variables. Results: During 2019, 152 deaths occurred after withdrawal of life-sustaining therapies, 10 of which would have been potentially eligible for donation after controlled circulatory death. We can anticipate a potential increase of 10 prospective donors, a maximum 21% growth in yearly transplantation activity, with a greater impact on kidney transplantation. For most patients, the time between withdrawal of organ support and death surpassed 120 minutes, an outcome explained by variations in withdrawal of life-sustaining measures and insufficient clinical records, underestimating the potential for controlled circulatory arrest donation. Conclusion: This study effectively highlights public health benefits of controlled circulatory arrest donation. Legislation allowing donation through this method represents a social gain and enables patients who will never meet brain death criteria to donate organs as part of the end-of-life process in intensive care medicine, within a framework of complete ethical alignment.
RESUMO
We compared epidemiology of intra-abdominal infection (IAI) between immunocompromised and non-immunocompromised ICU patients and identified risk factors for mortality. We performed a secondary analysis on the "AbSeS" database, a prospective, observational study with IAI patients from 309 ICUs in 42 countries. Immunocompromised status was defined as either neutropenia or prolonged corticosteroids use, chemotherapy or radiotherapy in the past year, bone marrow or solid organ transplantation, congenital immunodeficiency, or immunosuppressive drugs use. Mortality was defined as ICU mortality at any time or 28-day mortality for those discharged earlier. Associations with mortality were assessed by logistic regression. The cohort included 2589 patients of which 239 immunocompromised (9.2 %), most with secondary peritonitis. Among immunocompromised patients, biliary tract infections were less frequent, typhlitis more frequent, and IAIs were more frequently healthcare-associated or early-onset hospital-acquired compared with immunocompetent patients. No difference existed in grade of anatomical disruption, disease severity, organ failure, pathogens, and resistance patterns. Septic shock was significantly more frequent in the immunocompromised population. Mortality was similar in both groups (31.1% vs. 28.9 %; p = 0.468). Immunocompromise was not a risk factor for mortality (OR 0.98, 95 % CI 0.66-1.43). Independent risk factors for mortality among immunocompromised patients included septic shock at presentation (OR 6.64, 95 % CI 1.27-55.72), and unsuccessful source control with persistent inflammation (OR 5.48, 95 % CI 2.29-12.57). In immunocompromised ICU patients with IAI, short-term mortality was similar to immunocompetent patients, despite the former presented more frequently with septic shock, and septic shock and persistent inflammation after source control were independent risk factors for death.
RESUMO
PURPOSE: The primary objective of this study was to evaluate the associations between centre/country-based factors and two important process and outcome indicators in patients with hospital-acquired bloodstream infections (HABSI). METHODS: We used data on HABSI from the prospective EUROBACT-2 study to evaluate the associations between centre/country factors on a process or an outcome indicator: adequacy of antimicrobial therapy within the first 24 h or 28-day mortality, respectively. Mixed logistical models with clustering by centre identified factors associated with both indicators. RESULTS: Two thousand two hundred nine patients from two hundred one intensive care units (ICUs) were included in forty-seven countries. Overall, 51% (n = 1128) of patients received an adequate antimicrobial therapy and the 28-day mortality was 38% (n = 839). The availability of therapeutic drug monitoring (TDM) for aminoglycosides everyday [odds ratio (OR) 1.48, 95% confidence interval (CI) 1.03-2.14] or within a few hours (OR 1.79, 95% CI 1.34-2.38), surveillance cultures for multidrug-resistant organism carriage performed weekly (OR 1.45, 95% CI 1.09-1.93), and increasing Human Development Index (HDI) values were associated with adequate antimicrobial therapy. The presence of intermediate care beds (OR 0.63, 95% CI 0.47-0.84), TDM for aminoglycoside available everyday (OR 0.66, 95% CI 0.44-1.00) or within a few hours (OR 0.51, 95% CI 0.37-0.70), 24/7 consultation of clinical pharmacists (OR 0.67, 95% CI 0.47-0.95), percentage of vancomycin-resistant enterococci (VRE) between 10% and 25% in the ICU (OR 1.67, 95% CI 1.00-2.80), and decreasing HDI values were associated with 28-day mortality. CONCLUSION: Centre/country factors should be targeted for future interventions to improve management strategies and outcome of HABSI in ICU patients.

BACKGROUND: Hospital-acquired bloodstream infections are common in the intensive care unit (ICU) and have a high mortality rate. Patients with cirrhosis are especially susceptible to infections, yet there is a knowledge gap in the epidemiological distinctions in hospital-acquired bloodstream infections between cirrhotic and non-cirrhotic patients in the ICU. It has been suggested that cirrhotic patients, present a trend towards more gram-positive infections, and especially enterococcal infections. This study aims to describe epidemiological differences in hospital-acquired bloodstream infections between cirrhotic and non-cirrhotic patients hospitalized in the ICU regarding infection sources, microorganisms and mortality. METHODS: Using prospective Eurobact-2 international cohort study data, we compared hospital-acquired bloodstream infections sources and microorganisms in cirrhotic and non-cirrhotic patients. The association between Enterococcus faecium and cirrhosis was studied using a multivariable mixed logistic regression. The association between cirrhosis and mortality was assessed by a multivariable frailty Cox model. RESULTS: Among the 1059 hospital-acquired bloodstream infections patients included from 101 centers, 160 had cirrhosis. Hospital-acquired bloodstream infection source in cirrhotic patients was primarily abdominal (35.6%), while it was pulmonary (18.9%) for non-cirrhotic (p < 0.01). Gram-positive hospital-acquired bloodstream infections accounted for 42.3% in cirrhotic patients compared to 33.2% in non-cirrhotic patients (p = 0.02). Hospital-acquired bloodstream infections in cirrhotic patients were most frequently caused by Klebsiella spp (16.5%), coagulase-negative Staphylococci (13.7%) and E. faecium (11.5%). E. faecium bacteremia was more frequent in cirrhotic patients (11.5% versus 4.5%, p < 0.01). After adjusting for possible confounding factors, cirrhosis was associated with higher E. faecium hospital-acquired bloodstream infections risk (Odds ratio 2.5, 95% CI 1.3-4.5, p < 0.01). Cirrhotic patients had increased mortality compared to non-cirrhotic patients (Hazard Ratio 1.3, 95% CI 1.01-1.7, p = 0.045). CONCLUSIONS: Critically ill cirrhotic patients with hospital-acquired bloodstream infections exhibit distinct epidemiology, with more Gram-positive infections and particularly Enterococcus faecium.
RESUMO
AIMS: Drug-refractory electrical storm (ES) is a life-threatening medical emergency. We describe the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in drug-refractory ES without a reversible trigger, for which specific guideline recommendations are still lacking. METHODS AND RESULTS: Retrospective observational study in four Iberian centres on the indications, treatment, complications, and outcome of drug-refractory ES not associated with acute coronary syndromes, decompensated heart failure, drug toxicity, electrolyte disturbances, endocrine emergencies, concomitant acute illness with fever, or poor compliance with anti-arrhythmic drugs, requiring VA-ECMO for circulatory support. Thirty-four (6%) out of 552 patients with VA-ECMO for cardiogenic shock were included [71% men; 57 (44-62) years], 65% underwent cardiopulmonary resuscitation before VA-ECMO implantation, and 26% during cannulation. Left ventricular unloading during VA-ECMO was used in 8 (24%) patients: 3 (9%) with intraaortic balloon pump, 3 (9%) with LV vent, and 2 (6%) with Impella. Thirty (88%) had structural heart disease and 8 (24%) had an implantable cardioverter-defibrillator. The drug-refractory ES was mostly due to monomorphic ventricular tachycardia (VT) and ventricular fibrillation (VF) (59%), isolated monomorphic VT (26%), polymorphic VT (9%), or VF (6%). Thirty-one (91%) required deep sedation, 44% overdrive pacing, 36% catheter ablation, and 26% acute autonomic modulation. The main complications were nosocomial infection (47%), bleeding (24%), and limb ischaemia (21%). Eighteen (53%) were weaned from VA-ECMO, and 29% had heart transplantation. Twenty-seven (79%) survived to hospital discharge (48 (33-82) days). Non-survivors were older [62 (58-67) vs. 54 (43-58); P < 0.01] and had a higher first rhythm disorder-to-ECMO interval [0 (0-2) vs. 2 (1-11) days; P = 0.02]. Seven (20%) had rehospitalization during follow-up [29 (12-48) months], with ES recurrence in 6%. CONCLUSIONS: VA-ECMO bridged drug-refractory ES without a reversible trigger with a high success rate. This required prolonged hospital stays and coordination between the ECMO centre, the electrophysiology laboratory, and the heart transplant programme.

Abstract Background: Delirium is described as a distressful experience by patients and their families. Also, among healthcare staff, nurses caring for patients with delirium are the most at risk of high distress related to this syndrome. Aims: To assess nurses' distress related to delirium and its specific symptoms and severity. To identify factors nurses' sociodemographic and psychological characteristics and professional experience, that may be associated to this distress. Methods: A prospective study was carried out with nurses caring older adults with delirium in Intensive Care Medicine Service. Distress related to delirium, global psychological distress and burnout in nurses were measured with Delirium Experience Questionnaire, Kessler Psychological Distress Scale and Copenhagen Burnout Inventory, respectively. Results: Eighteen nurses were included (mean age=32 years; 89% women). About 46% of the nurses classified the experience of caring for patients in delirium as moderately distressing. Disorientation and psychomotor agitation were the most distressing symptoms. High distress related to delirium was associated with greater personal (p=0.040) and work-related burnout (p=0.020), and more global psychological distress (p=0.007). Conclusion: Caring for patients with delirium is distressing for nurses, particularly if the disorientation and psychomotor agitation are present and if nurses presented high burnout or psychological distress. This study highlights the need for development of education and support strategies for all professionals dealing with these patients.
Resumo Contexto: O delirium é descrito como uma experiência angustiante pelos pacientes e famílias. Também entre os profissionais de saúde, os enfermeiros que cuidam destes doentes são os que correm maior risco de grande distress relacionado com esta síndrome. Objetivos: Avaliar o distress dos enfermeiros relacionado com o delirium, os seus sintomas específicos e gravidade. Identificar fatores sociodemográficos e psicológicos e experiência profissional dos enfermeiros, que podem estar associados a este distress. Metodologia: Foi realizado um estudo prospetivo com enfermeiros que cuidam de idosos com delirium no Serviço de Medicina Intensiva. O distress relacionado com o delirium, distress psicológico global e burnout em enfermeiros foram medidos com Questionário Experiência de Delirium, Escala Distress Psicológico de Kessler e Inventário Burnout de Copenhaga, respetivamente. Resultados: Foram incluídos dezoito enfermeiros (média=32 anos; 89% mulheres). Cerca de 46% dos enfermeiros classificaram a experiência de cuidar de pacientes em delirium como moderadamente distressing. A desorientação e a agitação psicomotora, foram os sintomas mais distressing. O elevado distress relacionado com o delirium foi associado a um maior burnout pessoal (p=0,040) e relacionado com o trabalho (p=0,020), e mais distress psicológico global (p=0,007). Conclusões: Cuidar de doentes com delirium é distressing para os enfermeiros, particularmente se desorientação e agitação psicomotora estiverem presentes e se os enfermeiros apresentarem um elevado burnout ou distress psicológico. Este estudo salienta a necessidade do desenvolvimento de estratégias de formação e apoio para todos os profissionais que lidem com estes pacientes.

Conclusión: El cuidado de los pacientes con delirium es angustioso para los enfermeros, en particular si hay desorientación y agitación psicomotriz y si los enfermeros tienen un alto grado de burnout o distrés psicológico. Este estudio pone de manifiesto la necesidad de desarrollar estrategias de formación y apoyo para todos los profesionales que tratan con estos pacientes.
RESUMO
ABSTRACT Objective: To evaluate the association between different intensive care units and levels of brain monitoring with outcomes in acute brain injury. Methods: Patients with traumatic brain injury and subarachnoid hemorrhage admitted to intensive care units were included. Neurocritical care unit management was compared to general intensive care unit management. Patients managed with multimodal brain monitoring and optimal cerebral perfusion pressure were compared with general management patients. A good outcome was defined as a Glasgow outcome scale score of 4 or 5. Results: Among 389 patients, 237 were admitted to the neurocritical care unit, and 152 were admitted to the general intensive care unit. Neurocritical care unit management patients had a lower risk of poor outcome (OR = 0.228). A subgroup of 69 patients with multimodal brain monitoring (G1) was compared with the remaining patients (G2). In the G1 and G2 groups, 59% versus 23% of patients, respectively, had a good outcome at intensive care unit discharge; 64% versus 31% had a good outcome at 28 days; 76% versus 50% had a good outcome at 3 months (p < 0.001); and 77% versus 58% had a good outcome at 6 months (p = 0.005). When outcomes were adjusted by SAPS II severity score, using good outcome as the dependent variable, the results were as follows: for G1 compared to G2, the OR was 4.607 at intensive care unit discharge (p < 0.001), 4.22 at 28 days (p = 0.001), 3.250 at 3 months (p = 0.001) and 2.529 at 6 months (p = 0.006). Patients with optimal cerebral perfusion pressure management (n = 127) had a better outcome at all points of evaluation. Mortality for those patients was significantly lower at 28 days (p = 0.001), 3 months (p < 0.001) and 6 months (p = 0.001). Conclusion: Multimodal brain monitoring with autoregulation and neurocritical care unit management were associated with better outcomes and should be considered after severe acute brain injury.
RESUMO Objetivo: Avaliar a associação entre diferentes tipos de unidades de cuidados intensivos e os níveis de monitorização cerebral com desfechos na lesão cerebral aguda. Métodos: Foram incluídos doentes com traumatismo craniencefálico e hemorragia subaracnoide internados em unidades de cuidados intensivos. A abordagem na unidade de cuidados neurocríticos foi comparada à abordagem na unidade de cuidados intensivos polivalente geral. Os doentes com monitorização cerebral multimodal e pressão de perfusão cerebral ótima foram comparados aos que passaram por tratamento geral. Um bom desfecho foi definido como pontuação de 4 ou 5 na Glasgow outcome scale. Resultados: Dos 389 doentes, 237 foram admitidos na unidade de cuidados neurocríticos e 152 na unidade de cuidados intensivos geral. Doentes com abordagem em unidades de cuidados neurocríticos apresentaram menor risco de um mau desfecho (Odds ratio = 0,228). Um subgrupo de 69 doentes com monitorização cerebral multimodal (G1) foi comparado aos demais doentes (G2). Em G1 e G2, respectivamente, 59% e 23% dos doentes apresentaram bom desfecho na alta da unidade de cuidados intensivos; 64% e 31% apresentaram bom desfecho aos 28 dias; 76% e 50% apresentaram bom desfecho aos 3 meses (p < 0,001); e 77% e 58% apresentaram bom desfecho aos 6 meses (p = 0,005). Quando os desfechos foram ajustados para o escore de gravidade do SAPS II, usando o bom desfecho como variável dependente, os resultados foram os seguintes: para o G1, em comparação ao G2, a odds ratio foi de 4,607 na alta da unidade de cuidados intensivos (p < 0,001), 4,22 aos 28 dias (p = 0,001), 3,250 aos 3 meses (p = 0,001) e 2,529 aos 6 meses (p = 0,006). Os doentes com abordagem da pressão de perfusão cerebral ótima (n = 127) apresentaram melhor desfecho em todos os momentos de avaliação. A mortalidade desses doentes foi significativamente menor aos 28 dias (p = 0,001), aos 3 meses (p < 0,001) e aos 6 meses (p = 0,001). Conclusão: A monitorização cerebral multimodal com autorregulação e abordagem na unidade de cuidados neurocríticos foi associado a melhores desfechos e deve ser levado em consideração após lesão cerebral aguda grave.
RESUMO
RESUMO Objetivo: Avaliar a influência das características dos pacientes na hiperlactatemia em uma população admitida com infecção em unidades de terapia intensiva, bem como a influência da gravidade da hiperlactatemia na mortalidade hospitalar. Metódos: Foi realizada uma análise post hoc da hiperlactatemia no INFAUCI, um estudo nacional prospectivo, observacional e multicêntrico, que incluiu 14 unidades de terapia intensiva portuguesas. Foram selecionados pacientes admitidos com infecção em unidades de terapia intensiva com dosagem de lactato nas primeiras 12 horas de admissão. A sepse foi identificada de acordo com a definição Sepsis-2 aceita no momento da coleta de dados. A gravidade da hiperlactatemia foi classificada como leve (2 - 3,9mmol/L), moderada (4,0 - 9,9mmol/L) ou grave (> 10mmol/L). Resultados: De 1.640 pacientes admitidos com infecção, a hiperlactatemia ocorreu em 934 (57%) e foi classificada como leve, moderada e grave em 57,0%, 34,4% e 8,7% dos pacientes, respectivamente. A presença de hiperlactatemia e um maior grau de hiperlactatemia se associaram a um maior Simplified Acute Physiology Score II, a maior Índice de Comorbidade de Charlson e à presença de choque séptico. Em relação à curva Receiver Operating Characteristic do lactato para mortalidade hospitalar, foi encontrada área sob a curva de 0,64 (IC95% 0,61 - 0,72), que aumentou para 0,71 (IC95% 0,68 - 0,74) quando se combinou o Sequential Organ Failure Assessment. A mortalidade intra-hospitalar com outras covariáveis ajustadas pelo Simplified Acute Physiology Score II se associou à hiperlactatemia moderada e grave, com razão de chances de 1,95 (IC95% 1,4 - 2,7; p < 0,001) e 4,54 (IC95% 2,4 - 8,5; p < 0,001), respectivamente. Conclusão: Os níveis de lactato sanguíneo correlacionam-se independentemente com a mortalidade intra-hospitalar para graus moderados e graves de hiperlactatemia.
ABSTRACT Objective: To evaluate the influence of patient characteristics on hyperlactatemia in an infected population admitted to intensive care units and the influence of hyperlactatemia severity on hospital mortality. Methods: A post hoc analysis of hyperlactatemia in the INFAUCI study, a national prospective, observational, multicenter study, was conducted in 14 Portuguese intensive care units. Infected patients admitted to intensive care units with a lactate measurement in the first 12 hours of admission were selected. Sepsis was identified according to the Sepsis-2 definition accepted at the time of data collection. The severity of hyperlactatemia was classified as mild (2 - 3.9mmol/L), moderate (4.0 - 9.9mmol/L) or severe (> 10mmol/L). Results: In a total of 1,640 patients infected on admission, hyperlactatemia occurred in 934 patients (57%), classified as mild, moderate and severe in 57.0%, 34.4% and 8.7% of patients, respectively. The presence of hyperlactatemia and a higher degree of hyperlactatemia were both associated with a higher Simplified Acute Physiology Score II, a higher Charlson Comorbidity Index and the presence of septic shock. The lactate Receiver Operating Characteristic curve for hospital mortality had an area under the curve of 0.64 (95%CI 0.61 - 0.72), which increased to 0.71 (95%CI 0.68 - 0.74) when combined with Sequential Organ Failure Assessment score. In-hospital mortality with other covariates adjusted by Simplified Acute Physiology Score II was associated with moderate and severe hyperlactatemia, with odds ratio of 1.95 (95%CI 1.4 - 2.7; p < 0.001) and 4.54 (95%CI 2.4 - 8.5; p < 0.001), respectively. Conclusion: Blood lactate levels correlate independently with in-hospital mortality for moderate and severe degrees of hyperlactatemia.
RESUMO
RESUMO Objetivo: Avaliar se a infecção grave pelo SARS-CoV-2 está mais comumente associada a sinais de disfunção do trato corticoespinhal e outros sinais, sintomas e síndromes neurológicas, em comparação com outros agentes infecciosos. Métodos: Este foi um estudo de coorte prospectivo com inclusão consecutiva de doentes admitidos a unidades de cuidados intensivos devido a síndrome do desconforto respiratório agudo infeccioso primário, com necessidade de ventilação mecânica invasiva por > 48 horas. Os doentes incluídos foram atribuídos aleatoriamente a três investigadores para a avaliação clínica, a qual incluía a pesquisa de sinais de disfunção do trato corticoespinhal. Os dados clínicos, incluindo outras complicações neurológicas e possíveis preditores, foram obtidos independentemente a partir dos registros clínicos. Resultados: Foram incluídos consecutivamente 54 doentes com síndrome do desconforto respiratório agudo, 27 devido a SARS-CoV-2 e 27 devido a outros agentes infecciosos. Os grupos eram comparáveis na maioria das características. Os doentes com COVID-19 apresentavam risco significativamente superior de complicações neurológicas (RR = 1,98; IC95% 1,23 - 3,26). Os sinais de disfunção do trato corticoespinhal tendiam a ser mais prevalentes em doentes com COVID-19 (RR = 1,62; IC95% 0,72 - 3,44). Conclusão: Este estudo foi a primeira análise comparativa visando avaliar disfunção neurológica, entre doentes com infecção SARS-CoV-2 e outros agentes infecciosos, em um contexto de unidade de cuidados intensivos. Reportamos um risco significativamente superior de disfunção neurológica em doentes com COVID-19. Como tal, sugere-se o rastreio sistemático de complicações neurológicas em doentes com COVID-19 crítico.
ABSTRACT Objective: To evaluate whether critical SARS-CoV-2 infection is more frequently associated with signs of corticospinal tract dysfunction and other neurological signs, symptoms, and syndromes, than other infectious pathogens. Methods: This was a prospective cohort study with consecutive inclusion of patients admitted to intensive care units due to primary infectious acute respiratory distress syndrome requiring invasive mechanical ventilation > 48 hours. Eligible patients were randomly assigned to three investigators for clinical evaluation, which encompassed the examination of signs of corticospinal tract dysfunction. Clinical data, including other neurological complications and possible predictors, were independently obtained from clinical records. Results: We consecutively included 54 patients with acute respiratory distress syndrome, 27 due to SARS-CoV-2 and 27 due to other infectious pathogens. The groups were comparable in most characteristics. COVID-19 patients presented a significantly higher risk of neurological complications (RR = 1.98; 95%CI 1.23 - 3.26). Signs of corticospinal tract dysfunction tended to be more prevalent in COVID-19 patients (RR = 1.62; 95%CI 0.72 - 3.44). Conclusion: Our study is the first comparative analysis between SARS-CoV-2 and other infectious pathogens, in an intensive care unit setting, assessing neurological dysfunction. We report a significantly higher risk of neurological dysfunction among COVID-19 patients. As such, we suggest systematic screening for neurological complications in severe COVID-19 patients.
RESUMO
RESUMO Objetivo: Avaliar a qualidade de vida relacionada com a saúde e a incapacidade no primeiro mês após a alta para domicílio de todos os sobreviventes de COVID-19 grave internados por mais de 24 horas no Serviço de Medicina Intensiva. Metódos: Estudo realizado no Serviço de Medicina Intensiva do Centro Hospitalar Universitário São João, entre 8 de outubro de 2020 e 16 de fevereiro de 2021. Aproximadamente 1 mês após a alta para domicílio, uma enfermeira com experiência em medicina intensiva realizou uma consulta telefônica a 99 sobreviventes, aplicando os questionários EuroQol Five-Dimensional Five-Level e World Health Disability Assessment Schedule 2.0 - 12 itens. Resultados: A média de idade da população estudada foi de 63 ± 12 anos, e 32,5% foram submetidos à ventilação mecânica invasiva. O Simplified Acute Physiology Score médio foi de 35 ± 14, e o Índice de Comorbilidades de Charlson foi de 3 ± 2. O tempo de internamento em medicina intensiva e no hospital foi de 13 ± 22 e 22 ± 25 dias, respectivamente. A média da Escala Visual Analógica da EuroQol foi de 65% (± 21), sendo que apenas 35,3% dos sobreviventes não apresentaram ou tiveram problemas ligeiros para realizar suas atividades habituais, a maioria com algum grau de dor/desconforto e ansiedade/depressão. O World Health Disability Assessment Schedule 2.0 - 12 itens, mostrou incapacidade marcada em retomar o trabalho habitual ou atividades comunitárias e na mobilidade. O uso de ambas as ferramentas sugeriu que o estado de saúde dos sobreviventes seria pior do que a sua percepção. Conclusão: A identificação precoce de sequelas pode ajudar a definir fluxos e prioridades para a reabilitação e reinserção após a COVID-19 grave.
ABSTRACT Objective: To assess early postdischarge health-related quality of life and disability of all survivors of critical COVID-19 admitted for more than 24 hours to na intensive care unit.. Methods: Study carried out at the Intensive Care Medicine Department of Centro Hospitalar Universitário São João from 8th October 2020 to 16th February 2021. Approximately 1 month after hospital discharge, an intensive care-trained nurse performed a telephone consultation with 99 survivors already at home applying the EuroQol Five-Dimensional Five-Level questionnaire and the 12-item World Health Organization Disability Assessment Schedule 2.0. Results: The mean age of the population studied was 63 ± 12 years, and 32.5% were submitted to invasive mechanical ventilation. Their mean Simplified Acute Physiologic Score was 35 ± 14, and the Charlson Comorbidity Index was 3 ± 2. Intensive care medicine and hospital lengths of stay were 13 ± 22 and 22 ± 25 days, respectively. The mean EuroQol Visual Analog Scale was 65% (± 21), and only 35.3% had no or slight problems performing their usual activities, most having some degree of pain/discomfort and anxiety/depression. The 12-item World Health Organization Disability Assessment Schedule 2.0 showed marked impairments in terms of reassuring usual work or community activities and mobility. The use of both tools suggested that their health status was worse than their perception of it. Conclusion: This early identification of sequelae may help define flows and priorities for rehabilitation and reinsertion after critical COVID-19.
RESUMO
RESUMO Introdução: A Sociedade Portuguesa de Cuidados Intensivos e o Grupo de Infeção e Sépsis emitiram previamente recomendações visando à organização dos serviços de saúde e ao manejo dos doentes críticos com COVID-19. Em virtude da evolução do conhecimento, o painel de peritos voltou a se organizar para rever a atual evidência e emitir recomendações atualizadas. Métodos: Foi reunido um painel nacional de peritos que declararam não ter conflitos de interesse para o desenvolvimento das recomendações. Foram desenvolvidas perguntas operacionais conforme a metodologia PICO, e foi conduzida uma revisão sistemática rápida por meio da consulta de diferentes fontes bibliográficas. O painel determinou a direção e a força das recomendações com a utilização de duas rodadas de um método Delphi, conduzido seguindo princípios do sistema GRADE. Uma recomendação forte recebeu a redação "recomenda-se", e uma recomendação fraca foi redigida como "sugere-se". Resultados: Foram emitidas 48 recomendações e 30 sugestões abrangendo os seguintes tópicos: diagnóstico de infecção por SARS-CoV-2, coinfecção e superinfecção; critérios de admissão, cura e suspensão de isolamento; organização dos serviços; Equipamentos de Proteção Individual; terapêuticas de suporte respiratório e outras e terapêuticas específicas (antivirais, imunomodeladores e anticoagulação). Conclusão: Essas recomendações, especificamente orientadas para a realidade portuguesa, mas que podem se aplicar também aos Países Africanos de Língua Oficial Portuguesa e ao Timor-Leste, visam apoiar os profissionais de saúde no manejo de doentes críticos com COVID-19. Pretende-se que sejam constantemente revistas, de modo a refletir o avanço de nossa compreensão e o da terapêutica dessa patologia.
ABSTRACT Introduction: The Sociedade Portuguesa de Cuidados Intensivos and the Infection and Sepsis Group have previously issued health service and management recommendations for critically ill patients with COVID-19. Due to the evolution of knowledge, the panel of experts was again convened to review the current evidence and issue updated recommendations. Methods: A national panel of experts who declared that they had no conflicts of interest regarding the development of the recommendations was assembled. Operational questions were developed based on the PICO methodology, and a rapid systematic review was conducted by consulting different bibliographic sources. The panel determined the direction and strength of the recommendations using two Delphi rounds, conducted in accordance with the principles of the GRADE system. A strong recommendation received the wording "is recommended", and a weak recommendation was written as "is suggested." Results: A total of 48 recommendations and 30 suggestions were issued, covering the following topics: diagnosis of SARS-CoV-2 infection, coinfection and superinfection; criteria for admission, cure and suspension of isolation; organization of services; personal protective equipment; and respiratory support and other specific therapies (antivirals, immunomodulators and anticoagulation). Conclusion: These recommendations, specifically oriented to the Portuguese reality but that may also apply to Portuguese-speaking African countries and East Timor, aim to support health professionals in the management of critically ill patients with COVID-19. They will be continuously reviewed to reflect the progress of our understanding and the treatment of this pathology.

RESUMO A atual epidemia de COVID-19 foi declarada em 31 de dezembro de 2019 no mercado de frutos do mar da cidade de Wuhan, com rápida disseminação na China e, posteriormente, envolvendo múltiplos países (como maior expressão na Coreia do Sul, Japão, Itália e Irã) incluindo, desde 1º de março, Portugal. A maioria dos doentes infetados apresenta doença ligeira sem necessidade de hospitalização. Dentre os internados, de 6% a 10% necessitam de cuidados intensivos. As presentes recomendações visam facilitar a organização dos serviços de medicina intensiva para a resposta ao COVID-19, proporcionado os melhores cuidados aos doentes e protegendo os profissionais de saúde.
ABSTRACT Current COVID-19 epidemics was declared on December 31, 2019 at the Wuhan city seafood market, rapidly spreading throughout China, and later reaching several countries (mainly South Korea, Japan, Italy and Iran) and, since March 1, reaching Portugal. Most of the infected patients present with mild symptoms, not requiring hospitalization. Among those admitted to the hospital, 6% to 10% require admission to the intensive care unit. These recommendations are aimed to support the organization of intensive care services to respond COVID-19, providing optimized care to the patient and protection for healthcare professionals.
