- Critically ill patient mortality by age: long-term follow-up (CIMbA-LT)Publication . Gonçalves-Pereira, João; Oliveira, André; Vieira, Tatiana; Rodrigues, Ana Rita; Pinto, Maria João; Pipa, Sara; Martinho, Ana; Ribeiro, Sofia; Paiva, José-ArturBackgroundThe 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.MethodsThe 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.ResultsWe 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].ConclusionsCritically 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.
- High diversity of pathogenic Escherichia coli clones carrying mcr‐1 among gulls underlines the need for strategies at the environment–livestock–human interfacePublication . Ribeiro‐Almeida, Marisa; Mourão, Joana; Novais, Ângela; Pereira, Sofia; Freitas‐Silva, Joana; Ribeiro, Sofia; Martins da Costa, Paulo; Peixe, Luísa; Antunes, PatríciaThe expansion of mcr-carrying bacteria is a well-recognized public health problem. Measures to contain mcr spread have mainly been focused on the food-animal production sector. Nevertheless, the spread of MCR producers at the environmental interface particularly driven by the increasing population of gulls in coastal cities has been less explored. Occurrence of mcr-carrying Escherichia coli in gull's colonies faeces on a Portuguese beach was screened over 7 months. Cultural, molecular and genomic approaches were used to characterize their diversity, mcr plasmids and adaptive features. Multidrug-resistant mcr-1-carrying E. coli were detected for 3 consecutive months. Over time, multiple strains were recovered, including zoonotic-related pathogenic E. coli clones (e.g. B2-ST131-H22, A-ST10 and B1-ST162). Diverse mcr-1 genetic environments were mainly associated with ST2/ST4-HI2 (ST10, ST131, ST162, ST354 and ST4204) but also IncI2 (ST12990) plasmids or in the chromosome (ST656). Whole-genome sequencing revealed enrichment of these strains on antibiotic resistance, virulence and metal tolerance genes. Our results underscore gulls as important spreaders of high-priority bacteria and genes that may affect the environment, food-animals and/or humans, potentially undermining One-Health strategies to reduce colistin resistance.
- O suporte é básico e salva vidas uma história de sucesso da cadeia de sobrevivência:caso clinicoPublication . Costa, Hugo; Jacob, Miguel; Pereira, Rafaela; Ribeiro, SofiaReportamos um caso clínico de um jovem de 38 anos, vítima de paragem cardiorrespiratória em fibrilhação ventricular. O doente foi recuperado após 7 minutos de suporte básico de vida mais 26 minutos de suporte avançado de vida com 5 choques pelo monitor- desfibrilhador e LUCAS adaptado até à recuperação da circulação espontânea. Após estabilização o doente foi internado na Unidade de Cuidados Intensivos Polivalentes e posteriormente transferido para o serviço de Cardiologia, onde efetuou avaliação da anatomia coronária com coronárias sem lesões. Após descartadas as principais causas para o sucedido e passiveis de tratamento, o doente teve indicação para a colocação de um cardioversor - desfibrilhador- implantável. O caso clínico enaltece a rápida atuação e o elo de ligação da cadeia de sobrevivência, com suporte básico de vida e o contacto precoce com o centro de orientação de doentes urgentes, essenciais para a chegada em tempo útil da equipa de emergência médica e posterior ressuscitação cardiopulmonar avançada.
