BackgroundInfectious diseases are a common cause of increased morbidity and mortality in elderly patients. Bacteraemia in the elderly is a difficult diagnosis and a therapeutic challenge due to age-related vicissitudes and to their comorbidities. The main purpose of the study was to assess independent risk factors for in-hospital mortality among the elderly with bacteraemia admitted to an Internal Medicine Ward.MethodsOverall, a cohort of 135 patients, 65 years of age and older, with bacteraemia were retrospectively studied. Data related to demographic information, comorbidities, clinical parameters on admission, source and type of infection, microorganism isolated in the blood culture, laboratory data and empirical antibiotic treatment was recorded from each patient. Multivariate logistic regression was performed to identify independent predictors of all-cause in-hospital mortality.ResultsOf these 135 patients, 45.9% were women. The most common infections in this group of patients were urinary tract infections (46.7%). The main microorganisms isolated in the blood cultures were Escherichia coli (14.9%), Methicillin-resistant Staphylococcus aureus (MRSA) (12.0%), non-MRSA (11.4%), Klebsiella pneumoniae (9.1%) and Enterococcus faecalis (8.0%). The in-hospital mortality was 22.2%. Independent prognostic factors associated with in-hospital mortality were age ≥ 85 years, chronic renal disease, bacteraemia of unknown focus and cognitive impairment at admission (OR, 2.812 [95% CI, 1.039-7.611; p = 0.042]; OR, 6.179 [95% CI, 1.840-20.748; p = 0.003]; OR, 8.673 [95% CI, 1.557-48.311; p = 0.014] and OR, 3.621 [95% CI, 1.226-10.695; p = 0.020], respectively). By multivariate analysis appropriate antibiotic therapy was not associated with lower odds of mortality.ConclusionBacteraemia in the elderly has a high mortality rate. There are no set of signs or clinical features that can predict bacteraemia in the elderly. However, older age (≥ 85 years), chronic renal disease, bacteraemia of unknown focus and severe cognitive impairment adversely affects the outcome of elderly patients with bacteraemia admitted to an Internal Medicine ward.
Background The Clinical Frailty Scale (CFS) is frequently used to measure frailty in critically ill adults. There is wide variation in the approach to analysing the relationship between the CFS score and mortality after admission to the ICU. This study aimed to evaluate the influence of modelling approach on the association between the CFS score and short-term mortality and quantify the prognostic value of frailty in this context. Methods We analysed data from two multicentre prospective cohort studies which enrolled intensive care unit patients ≥ 80 years old in 26 countries. The primary outcome was mortality within 30-days from admission to the ICU. Logistic regression models for both ICU and 30-day mortality included the CFS score as either a categorical, continuous or dichotomous variable and were adjusted for patient’s age, sex, reason for admission to the ICU, and admission Sequential Organ Failure Assessment score. Results The median age in the sample of 7487 consecutive patients was 84 years (IQR 81–87). The highest fraction of new prognostic information from frailty in the context of 30-day mortality was observed when the CFS score was treated as either a categorical variable using all original levels of frailty or a nonlinear continuous variable and was equal to 9% using these modelling approaches (p < 0.001). The relationship between the CFS score and mortality was nonlinear (p < 0.01). Conclusion Knowledge about a patient’s frailty status adds a substantial amount of new prognostic information at the moment of admission to the ICU. Arbitrary simplification of the CFS score into fewer groups than originally intended leads to a loss of information and should be avoided. Trial registration NCT03134807 (VIP1), NCT03370692 (VIP2)
SUMÁRIOApesar de a maioria dos doentes tratados com amiodarona permanecer em eutiroidia, alguns desenvolvem hipertiroidismo (HPEIA) ou hipotiroidismo (HPOIA) induzidos pela amiodarona. Os autores apresentam uma análise retrospectiva dos processos de dez doentes com disfunção tiróidea induzida pela amiodarona. Verificou-se que seis doentes eram mulheres e que o tempo médio de toma da amiodarona foi de 17,7 meses. O HPOIA foi o mais frequente (seis doentes). Dos doentes com HPEIA, dois tinham HPEIA tipo 2, um tipo 1 e um tipo 3. Sintomas sugestivos de disfunção tiróidea ocorreram em cinco doentes, a maioria com HPOIA. No HPEIA, a clínica mais comum foi exacerbação da arritmia de base (três doentes). A interrupção da amiodarona e administração de levotiroxina foi a terapêutica escolhida em 83,3% dos casos de HPOIA, enquanto a tionamida associada a corticoide com suspensão da amiodarona foi opção em 75% dos casos de HPEIA. Registraram-se três óbitos, todos com HPEIA. O HPEIA constituiu uma complicação potencialmente fatal. A clínica pode ser vaga, pelo que a monitorização da função tiróidea é obrigatória. Arq Bras Endocrinol Metab. 2013;57(1):71-8 SUMMARYAlthough most patients remain clinically euthyroid, some develop amiodarone-induced hyperthyroidism (HPEAI) or hypothyroidism (HPOAI). The authors present a retrospective analysis of ten patients with amiodarone-induced thyroid dysfunction. Six patients were female and mean amiodarone intake was 17.7 months. HPOIA was more common (six patients). From all the patients with HPEAI, two had type 2, one had type 1, and one had type 3 hyperthyroidism. Symptoms suggestive of thyroid dysfunction occurred in five patients, most of them with HPOAI. In HPEAI, the most frequent symptom was exacerbation of arrhythmia (three patients). Discontinuation of amiodarone and treatment with levothyroxine was chosen in 83.3% of the HPOAI cases, while thyonamide treatment with corticosteroids and without amiodarone was the option in 75% of the HPEAI cases. There were three deaths, all in patients with HPEAI. HPEAI is potentially fatal. The clinical picture may be vague, so the thyroid monitoring is mandatory. IntROdUçãO A disfunção tiróidea induzida pela amiodarona (DTIA) é uma complicação potencialmente grave, cuja incidência é estimada entre 2% e 24% (1,2).A amiodarona, um antiarrítmico da classe 3 da classificação de Vaughan Williams, introduzida em 1962 como antianginoso, foi aprovada pela Food and Drug Administration em 1985 para o tratamento de taquiarritmias supraventriculares (1,2). Constitui um dos fár-macos mais utilizados atualmente para manutenção do ritmo sinusal em doentes com fibrilhação auricular (1) e recentemente foi incluída nas diretivas da American Heart Association como um dos fármacos utilizados na paragem cardíaca (3). Contudo, está associada a vários efeitos secundários, que ocorrem em cerca de 80% dos doentes. Os efeitos mais frequentes são microdepósitos córneos (quase 100%), perturbações gastrointestinais benignas (80%), fotossensibilidade e hiperpigmentação cu...
The Ehlers-Danlos syndrome type IV (EDS-IV) is a hereditary, autosomal dominant disease that causes a defect in the procollagen III synthesis, which results in a structural modification in this protein. An awareness of the disease is of vital importance for the optimal outcome, since the affected individuals have a high risk of vascular, intestinal and uterine rupture. It's a disease with great clinical variability and the diagnosis is confirmed by detection of a mutation in the gene encoding collagen type III. The authors present a case report of a patient who appeared at the emergency ward with acute abdomen and hypovolemic shock after spontaneous aortic rupture. The diagnosis was confirmed after genetic study that identified a mutation in the (c.970G>A) in the COL3A1 gene, only reported once in the literature in a family with internal carotid dissections in some of its members. It's the first time that this mutation is reported in association with the EDS-IV. The authors also make a brief review of the clinical, genetic and molecular characteristics of this syndrome.
