Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
Um surto de intoxicação por Cycas revoluta ocorreu no município de Pesqueira no agreste de Pernambuco. Durante a severa seca ocorrida durante o ano de 2013 o proprietário alimentou suas vacas com Cycas revoluta misturada com capim elefante (Pennisetum purpureum). Os animais apresentaram anorexia, atonia ruminal, discreta icterícia, hemorragias petequiais nas mucosas ocular e vulvar, ascite, fezes enegrecidas e com muco e decúbito. As atividades séricas de aspartato amino transferase e gama glutamil transferase estavam aumentadas e a proteína sérica total e a albumina estavam diminuídas. As 12 vacas que ingeriram a planta adoeceram e cinco morreram apresentando necrose centrolobular difusa do fígado. Em épocas de severa estiagem a administração de plantas de toxicidade desconhecida pelos produtores é uma das formas mais frequentes de intoxicação de animais de produção na região nordeste do Brasil.
Introdução: O nosso objetivo foi avaliar as diferenças entre a colocação precoce ou tardia do cateter ureteral duplo J em doentes com urosépsis associada a litíase do trato urinário. Material e Métodos: Revisão retrospectiva de doentes internados na nossa instituição entre 2011 e 2015 com o diagnóstico de urosépsis associada a litíase do trato urinário, com colocação de cateter ureteral duplo J. Os grupos de cateterização precoce e tardia foram definidos pela mediana de espera pela colocação de cateter ureteral duplo J. Analisou-se o tempo de internamento, localização e emissão espontânea de cálculos após a colocação do cateter ureteral. A análise estatística incluiu teste de qui-quadrado, regressão linear e correlação de Spearman. Resultados: Quarenta e dois doentes (média de idade: 58 anos; 32 mulheres) apresentaram uma média de 3,38 dias desde a admissão no serviço de urgência até à colocação de cateter ureteral duplo J. A mediana de tempo para cateterismo ureteral foi 2,5 dias.Otempo médio de internamento foi 12,2 dias. O grupo de cateterismo precoce teve um tempo de internamento menor do que o grupo de cateterismo tardio (média de 5,6 vs 18,8 dias; p<0,001). O grupo de cateterismo ureteral precoce apresentou cálculos predominantemente lombares face ao grupo tardio (76,2% vs 42,8%; p=0,029) e apresentou melhor emissão espontânea de cálculos comparativamente a esse grupo (61,9% vs 47,6%; p=0,268). Se considerarmos apenas os cálculos lombares, existe uma relação na emissão espontânea entre os dois grupos ( p=0,027). Conclusão: Existe redução significativa do tempo de internamento, em doentes com urosépsis por litíase, quando é realizado o cateterismo ureteral precoce. Este apresenta uma maior emissão espontânea de cálculos, sobretudo na região lombar.
trabalho tem por objetivo verificar os níveis séricos hormonais de triiodotironina (T3) e tiroxina (T4) em ovelhas diagnosticadas com toxemia da prenhez (TP), bem como avaliar sua participação e reflexo neste tipo de transtorno metabólico. Foram analisadas as fichas clínicas de 24 ovelhas atendidas na Clínica de Bovinos, Campus Garanhuns/UFRPE, diagnosticadas com TP, no período de 2007 a 2012. Os animais foram submetidos ao exame clínico e ultrassonográfico, seguido de coleta de sangue e urina para exames laboratoriais. As principais alterações clínicas apresentadas pelos animais foram apatia, aumento da temperatura corporal, mucosas congestas, desidratação, edema dos membros, amaurose, taquicardia, inapetência a anorexia, diminuição da motilidade ou atonia ruminal. Vieram a óbito 50 % dos animais, destes 58,33% estavam hiperglicêmicos. A pesquisa de corpos cetônicos revelou um quadro de cetonúria. Quanto a glicemia, foram constatadas três condições nas ovelhas com TP. Os resultados laboratoriais revelaram valores elevados para ácidos graxos não-esterificados (AGNES) e β-hidroxibutirato (BHB). Enquanto que a média dos níveis séricos de T3 (3,21 nmol/L) e de T4 (69,16 nmol/L) nas ovelhas com TP foram consideradas como de baixas concentrações. Dessa forma, é possível concluir que a TP é caracterizada por alterações endócrinas que refletem o estado de balanço energético negativo em que as ovelhas acometidas se encontram.

Analyses were performed of the clinical cases of 24 ewes diagnosed with PT and treated at the Bovine Clinic of the University Federal Rural of Pernambuco, Campus Garanhuns, from 2007 to 2012. The animals were submitted to clinical and ultrasound exams. Blood and urine were collected for the laboratory exams. The main abnormalities were apathy, elevated body temperature, congested mucosa, dehydration, edema in the limbs, amaurosis, tachycardia, inappetence or anorexia and diminished ruminal motility. The mortality rate was 50%. Among the animals that died, 58.33% were hyperglycemic. The study of ketone bodies revealed ketonuria. Three conditions of glycemia were found in the ewes with PT. The laboratory findings revealed high levels of non-esterified fatty acids and β-hydroxybutyric acid. Serum levels of T3 (3.21 nmol/L) and T4 (69.16 nmol/L) were low. In conclusion, pregnancy toxemia in ewes is characterized by endocrine alterations that reflect a negative energy balance..
