Critically ill patient mortality by age: long-term follow-up (CIMbA-LT).

BACKGROUND: The past years have witnessed dramatic changes in the population admitted to the intensive care unit (ICU). Older and sicker patients are now commonly treated in this setting due to the newly available sophisticated life support. However, the short- and long-term benefit of this strategy is scarcely studied. METHODS: The Critically Ill patients' mortality by age: Long-Term follow-up (CIMbA-LT) was a multicentric, nationwide, retrospective, observational study addressing short- and long-term prognosis of patients admitted to Portuguese multipurpose ICUs, during 4 years, according to their age and disease severity. Patients were followed for two years after ICU admission. The standardized hospital mortality ratio (SMR) was calculated according to the Simplified Acute Physiology Score (SAPS) II and the follow-up risk, for patients discharged alive from the hospital, according to official demographic national data for age and gender. Survival curves were plotted according to age group. RESULTS: We included 37.118 patients, including 15.8% over 80 years old. The mean SAPS II score was 42.8 ± 19.4. The ICU all-cause mortality was 16.1% and 76% of all patients survive until hospital discharge. The SAPS II score overestimated hospital mortality [SMR at hospital discharge 0.7; 95% confidence interval (CI) 0.63-0.76] but accurately predicted one-year all-cause mortality [1-year SMR 1.01; (95% CI 0.98-1.08)]. Survival curves showed a peak in mortality, during the first 30 days, followed by a much slower survival decline thereafter. Older patients had higher short- and long-term mortality and their hospital SMR was also slightly higher (0.76 vs. 0.69). Patients discharged alive from the hospital had a 1-year relative mortality risk of 6.3; [95% CI 5.8-6.7]. This increased risk was higher for younger patients [21.1; (95% CI 15.1-39.6) vs. 2.4; (95% CI 2.2-2.7) for older patients]. CONCLUSIONS: Critically ill patients' mortality peaked in the first 30 days after ICU admission. Older critically ill patients had higher all-cause mortality, including a higher hospital SMR. A long-term increased relative mortality risk was noted in patients discharged alive from the hospital, but this was more noticeable in younger patients.

Fighting the pandemic with collaboration at heart: Report from cardiologists in a COVID-19-dedicated Portuguese intensive care unit.

INTRODUCTION AND OBJECTIVES: The coronavirus disease 2019 (COVID-19) spread quickly around the world. Although mainly a respiratory illness, there is growing interest in non-respiratory manifestations, particularly cardiovascular ones. At our center, mobilization of cardiologists with intensive care training was needed. Our aim is to describe patients with severe COVID-19 admitted to a Portuguese intensive care unit (ICU), the cardiovascular impact of the disease and the experience of cardiologists working in a COVID-19 ICU. METHODS: Data from adult patients with COVID-19 admitted to the ICU of Centro Hospitalar de Vila Nova de Gaia/Espinho between 16 March 2020 and 21 April 2020 were analyzed retrospectively. RESULTS: Thirty-five patients were admitted. Mean age was 62.6±6.0 years and 23 (65.7%) were male. Dyslipidemia was the most common cardiovascular risk factor (65.7%, n=23), followed by hypertension (57.1%, n=20). Mean ICU stay time was 15.9±10.0 days. Patients had high rates of mechanical ventilation (88.6%, n=31) and vasopressor support (88.6%, n=31). Low rates of new onset left systolic dysfunction were detected (8.5%, n=2). One patient required venoarterial extra-corporeal membrane oxygenation. Mortality was 25% (n=9). Acute myocardial injury and N-terminal pro-B-type natriuretic peptide (NT-proBNP) elevation was detected in 62.9% (n=22). Patients that died had higher NT-proBNP compared to those discharged alive (p<0.05). Care by cardiologists frequently changed decision making. CONCLUSIONS: The cardiovascular impact of COVID-19 seems relevant but is still widely unknown. Studies are needed to clarify the role of cardiac markers in COVID-19 prognosis. Multidisciplinary care most likely results in improved patient care.

INTRODUÇÃO E OBJETIVOS: A doença pelo novo coronavirus (COVID-19) espalhou-se rapidamente pelo globo. Embora tenha atingimento essencialmente respiratório, existe interesse nas manifestações extrarrespiratórias, nomeadamente nas cardiovasculares. No nosso centro, foi necessária a mobilização de cardiologistas com experiência em cuidados intensivos para enfrentar este desafio. O objetivo desta investigação é descrever a população internada com COVID-19 grave numa UCI portuguesa, o impacto cardiovascular desta doença e a nossa experiência enquanto cardiologistas numa UCI COVID-19. MÉTODOS: Dados de adultos com COVID-19 internados na UCI do Centro Hospitalar de Vila Nova de Gaia/Espinho entre 16/03/2020 e 21/04/2020 foram analisados retrospetivamente. RESULTADOS: Foram internados 35 doentes. A média de idade foi 62,6±6,0 anos e 23 (65,7%) doentes eram homens. A dislipidemia foi o fator de risco cardiovascular mais prevalente (65,7%, n=23), seguida pela hipertensão (57,1%, n=20). O tempo médio de internamento em UCI foi 15,9±10,0 dias. A necessidade de ventilação mecânica (88,6%, n=31) e suporte vasopressor (88,6%, n=31) foi alta, mas poucos doentes desenvolveram disfunção sistólica de novo (n=2,85%). A mortalidade foi de 25% (n=9). Foi detetada lesão miocárdica aguda e elevação do NT-proBNP em 62,9% (n=22) dos doentes, sendo os níveis de NT-proBNP mais elevados nos doentes que faleceram (p<0,05). A participação de cardiologistas na UCI alterou frequentemente a decisão clínica. CONCLUSÃO: O impacto cardiovascular da COVID-19 parece relevante mas é parcamente conhecido, sendo necessários mais estudos para clarificar o papel dos marcadores cardíacos no prognóstico da COVID-19. As equipas multidisciplinares provavelmente melhoram os cuidados de saúde prestados a estes doentes.

Original Intracerebral Hemorrhage Score for the Prediction of Short-Term Mortality in Cerebral Hemorrhage: Systematic Review and Meta-Analysis.

OBJECTIVES: To systematically assess the discrimination and calibration of the Intracerebral Hemorrhage score for prediction of short-term mortality in intracerebral hemorrhage patients and to study its determinants using heterogeneity analysis. DATA SOURCES: PubMed, ISI Web of Knowledge, Scopus, and CENTRAL from inception to September 15, 2018. STUDY SELECTION: Adult studies validating the Intracerebral Hemorrhage score for mortality prediction in nontraumatic intracerebral hemorrhage at 1 month/discharge or sooner. DATA EXTRACTION: Data were collected on the following aspects of study design: population studied, level of care, timing of outcome measurement, mean study year, and mean cohort Intracerebral Hemorrhage score. The summary measures of interest were discrimination as assessed by the C-statistic and calibration as assessed by the standardized mortality ratio (observed:expected mortality ratio). Random effect models were used to pool both measures. Heterogeneity was measured using the I statistic and explored using subgroup analysis and meta-regression. DATA SYNTHESIS: Fifty-five studies provided data on discrimination, and 35 studies provided data on calibration. Overall, the Intracerebral Hemorrhage score discriminated well (pooled C-statistic 0.84; 95% CI, 0.82-0.85) but overestimated mortality (pooled observed:expected mortality ratio = 0.87; 95% CI, 0.78-0.97), with high heterogeneity for both estimates (I 80% and 84%, respectively). Discrimination was affected by study mean Intracerebral Hemorrhage score (ß = -0.05), and calibration was affected by disease severity, with the score overestimating mortality for patients with an Intracerebral Hemorrhage score greater than 3 (observed:expected mortality ratio = 0.84; 95% CI, 0.78-0.91). Mortality rates were reproducible across cohorts for patients with an Intracerebral Hemorrhage score 0-1 (I = 15%). CONCLUSIONS: The Intracerebral Hemorrhage score is a valid clinical prediction rule for short-term mortality in intracerebral hemorrhage patients but discriminated mortality worse in more severe cohorts. It also overestimated mortality in the highest Intracerebral Hemorrhage score patients, with significant inconsistency between cohorts. These results suggest that mortality for these patients is dependent on factors not included in the score. Further studies are needed to determine these factors.

NT-pro-BNP correlates with disease severity and predicts outcome in cerebral haemorrhage patients: Cohort study.

BACKGROUND: Intracerebral haemorrhage (ICH) is a devastating condition, with more than half of patients dying or becoming dependent after such an event. Natriuretic peptides, frequently used in the management of heart failure, have been shown to correlate with disease severity and prognosis in brain disorders. The aim of this study was to test the hypothesis that NT-pro-BNP correlates with disease severity and is an independent prognostic marker for non-traumatic ICH patients. METHODS: A consecutive sample of 201 non-traumatic ICH patients, who were non-comatose on admission and medically treated in a stroke unit, were evaluated for in-hospital mortality and three-month functional dependency (modified Rankin Scale >2). NT-pro-BNP measurement was performed after admission. Independent predictors of the outcomes in study were assessed using logistic regression and the incremental value of NT-pro-BNP on three previously validated severity scores was evaluated using the variation in C-statistic (Δc). Values of p < .05 were considered significant. RESULTS: In-hospital mortality rate was 8.0%, and 40.3% of patients achieved good functional outcome. NT-pro-BNP correlated with hematoma volume (r = 0.186) and amount of intraventricular blood (r = 0.240). Higher levels of NT-pro-BNP were independently associated with death (Expß = 1.650) and functional dependency (Expß = 1.449). NT-pro-BNP increased the discrimination of the ICH-GS for mortality prediction (Δc = 0.043) and of FUNC and ICH scores for functional outcome prediction (Δc = 0.060 and 0.055 respectively). Admission NT-pro-BNP levels were independently associated with hematoma size. CONCLUSIONS: NT-pro-BNP is an independent prognostic factor for low-risk non-traumatic ICH patients and a valid marker of disease severity in this patient population.

Assessment and Comparison of the Four Most Extensively Validated Prognostic Scales for Intracerebral Hemorrhage: Systematic Review with Meta-analysis.

BACKGROUND/OBJECTIVE: Intracerebral hemorrhage (ICH) is a devastating disorder, responsible for 10% of all strokes. Several prognostic scores have been developed for this population to predict mortality and functional outcome. The aim of this study was to determine the four most frequently validated and most widely used scores, assess their discrimination for both outcomes by means of a systematic review with meta-analysis, and compare them using meta-regression. METHODS: PubMed, ISI Web of Knowledge, Scopus, and CENTRAL were searched for studies validating the ICH score, ICH-GS, modified ICH, and the FUNC score in ICH patients. C-statistic was chosen as the measure of discrimination. For each score and outcome, C-statistics were aggregated at four different time points using random effect models, and heterogeneity was evaluated using the I2 statistic. Score comparison was undertaken by pooling all C-statistics at different time points using robust variance estimation (RVE) and performing meta-regression, with the score used as the independent variable. RESULTS: Fifty-three studies were found validating the original ICH score, 14 studies were found validating the ICH-GS, eight studies were found validating the FUNC score, and five studies were found validating the modified ICH score. Most studies attempted outcome prediction at 3 months or earlier. Pooled C-statistics ranged from 0.76 for FUNC functional outcome prediction at discharge to 0.85 for ICH-GS mortality prediction at 3 months, but heterogeneity was high across studies. RVE showed the ICH score retained the highest discrimination for mortality (c = 0.84), whereas the modified ICH score retained the highest discrimination for functional outcome (c = 0.80), but these differences were not statistically significant. CONCLUSIONS: The ICH score is the most extensively validated score in ICH patients and, in the absence of superior prediction by other scores, should preferably be used. Further studies are needed to validate prognostic scores at longer follow-ups and assess the reasons for heterogeneity in discrimination.

Prognostic models for intracerebral hemorrhage: systematic review and meta-analysis.

BACKGROUND: Prognostic tools for intracerebral hemorrhage (ICH) patients are potentially useful for ascertaining prognosis and recommended in guidelines to facilitate streamline assessment and communication between providers. In this systematic review with meta-analysis we identified and characterized all existing prognostic tools for this population, performed a methodological evaluation of the conducting and reporting of such studies and compared different methods of prognostic tool derivation in terms of discrimination for mortality and functional outcome prediction. METHODS: PubMed, ISI, Scopus and CENTRAL were searched up to 15th September 2016, with additional studies identified using reference check. Two reviewers independently extracted data regarding the population studied, process of tool derivation, included predictors and discrimination (c statistic) using a predesignated spreadsheet based in the CHARMS checklist. Disagreements were solved by consensus. C statistics were pooled using robust variance estimation and meta-regression was applied for group comparisons using random effect models. RESULTS: Fifty nine studies were retrieved, including 48,133 patients and reporting on the derivation of 72 prognostic tools. Data on discrimination (c statistic) was available for 53 tools, 38 focusing on mortality and 15 focusing on functional outcome. Discrimination was high for both outcomes, with a pooled c statistic of 0.88 for mortality and 0.87 for functional outcome. Forty three tools were regression based and nine tools were derived using machine learning algorithms, with no differences found between the two methods in terms of discrimination (p = 0.490). Several methodological issues however were identified, relating to handling of missing data, low number of events per variable, insufficient length of follow-up, absence of blinding, infrequent use of internal validation, and underreporting of important model performance measures. CONCLUSIONS: Prognostic tools for ICH discriminated well for mortality and functional outcome in derivation studies but methodological issues require confirmation of these findings in validation studies. Logistic regression based risk scores are particularly promising given their good performance and ease of application.

Acute hepatitis C from heterosexual transmission.

The diagnosis of acute hepatitis C (HCV) infection is rare since the majority of cases are asymptomatic, which makes the infection usually detected in a chronic phase, most of the time using serological tests. The main route of HCV transmission is percutaneous, with sexual transmission occurring more often in men who have sex with men. The analytical alterations of acute hepatitis C are varied but usually present with ALT elevation higher than AST, very rarely with hepatic insufficiency. We report a case of a patient with a clinical and analytical picture compatible with toxic acute hepatitis, accompanied by hepatic insufficiency, with negative serology for hepatotropic viruses and with no history compatible with the use of substances with hepatic toxicity other than alcohol. During the diagnostic investigation it was concluded that the patient had acute HCV hepatitis and that the transmission route was heterosexual.

Hepatocellular carcinoma after direct-acting antiviral therapy for chronic HCV infection: Is it a real risk?

The newer oral treatments for chronic hepatitis C virus infection are one of the greatest revolutions in modern medicine. These drugs promise to eradicate the infection, showing high cure rates even in difficult to treat populations with very few side effects. Nevertheless, some cases of recurrence and de novo hepatocellular carcinoma after treatment with these drugs have been reported. We describe two cases of patients treated with direct-acting antiviral agents that developed hepatocarcinoma during follow-up post-treatment.

A Rare and Potentially Catastrophic Infection: Primary Intestinal Aspergillosis-Case Report in an HIV Patient.

Aspergillus species are ubiquitous in nature; however, infection is uncommon, except in immunocompromised or immunosuppressed hosts. We present the case of a 71-year-old woman with a history of human immunodeficiency virus infection who presented with fever, weight loss, and diarrhea, posteriorly diagnosed with intestinal aspergillosis after examination of a segmental enterectomy piece. The diagnosis was made postmortem once the patient died after fast and progressive deterioration in the postoperative period.

Fecal microbiota transplantation as a potential way to eradicate multiresistant microorganisms.

Multiresistant microorganism infection often can produce a life-threatening situation. We report two cases in which fecal microbiota transplantation used for the treatment of recurrent Clostridium difficile infection were effective in eradicating colonization by carbapenemase-producing Enterobacteriaceae. The presented cases illustrate the potential benefit of fecal microbiota transplantation in resolution of asymptomatic carrier states of multiresistant microorganisms, suggesting the need for further investigations with a view to their applicability in this area.
