RESUMEN
BACKGROUND: New therapies have revolutionized the treatment of Crohn's disease (CD), but in some countries, the surgery rate has not changed, the frequency of emergency surgery is underestimated, and surgical risk is poorly studied. AIMS: The aim of this study was to identify risk factors and clinical indications for primary surgery in CD patients at the tertiary hospital. METHODS: This was a retrospective cohort of a prospectively collected database of 107 patients with CD from 2015 to 2021. The main outcomes were the incidence of surgery treatment, types of procedures performed, surgical recurrence, surgery free time, and risk factors for surgery. RESULTS: Surgical intervention was performed in 54.2% of the patients, and most of the procedures were emergency surgeries (68.9%). The elective procedures (31.1%) were performed over 11 years after diagnosis. The main indications for surgery were ileal stricture (34.5%) and anorectal fistulas (20.7%). The most frequent procedure was enterectomy (24.1%). Recurrence surgery was most common in emergency procedures (OR 2.1; 95%CI 1.6-6.6). Montreal phenotype L1 stricture behavior (RR 1.3; 95%CI 1.0-1.8, p=0.04) and perianal disease (RR 1.43; 95%CI 1.2-1.7) increased the risk of emergency surgeries. The multiple linear regression showed age at diagnosis as a risk factor for surgery (p=0.004). The study of surgery free time showed no difference in the Kaplan-Meier curve for Montreal classification (p=0.73). CONCLUSIONS: The risk factors for operative intervention were strictures in ileal and jejunal diseases, age at diagnosis, perianal disease, and emergency indications.

BACKGROUND: An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant was detected in the psychiatric ward of a general hospital in Brasília, Brazil. METHODS: We report the investigation, clinical outcomes, viral sequencing, and control measures applied to outbreak containment. RESULTS: The overall attack rate was 95% (23/24) in a period of 13 days. Among the cases, 78% (18/23) were vaccinated and 17% (4/23) required intensive care. The Omicron variant was isolated from the 19 sequenced samples. CONCLUSIONS: The findings highlight the potential harm that highly transmissible variants may generate among hospitalized populations, particularly those with comorbidities.

AIM: The main goal in Crohn´s disease (CD) is a sustained suppression of inflammatory activity associated with mucosa healing in endoscopic evaluation. During clinical routine, there are small numbers of good markers to monitor inflammatory activity under treatment. We postulated that Oral 67Gallium Citrate Scintigraphy is able to mark inflammatory disease in mucosa and deep inflammation in CD, when used in oral form. OBJECTIVE: Measure the accuracy of Oral 67Gallium Citrate Scintigraphy in intestinal inflammatory activity of Crohn´s disease. PATIENTS AND METHODS: In a prospective consecutive cross-sectional study from January 2018 to June 2019, the ileocolonic region of 32 patients with CD were studied by dividing into four regions of interest (ROI) from the ileum to the rectum. A total of 128 intestinal segments were analyzed in cluster data. Accuracy values of Oral 67Gallium Scintigraphy and colonoscopy tests were evaluated with the histological reference test. Values of the respective receiver operating characteristic (ROC) curves were obtained and compared. The reliability between the tests was evaluated by Kappa statistical with the segment-level analyses using variance adjustments. All statistical analyses were performed with a test significance level of 0.05. RESULTS: The study population included 32 patients with CD (10 men, 22 women; average age 39 years). Disease time was five years on average. Anti-TNFs treatment was found in 71%. The most found phenotype of the Montreal classification was L3. Differences in ROC curves for colonoscopy (0.94) and Oral 67Ga Scintigraphy (0.96) did not show significant value (p = 0.32). The sensitivity of scintigraphy to detect intestinal inflammatory activity in CD was 64%, specificity of 96% and accuracy of 84%. A high agreement was found between oral scintigraphy and histological measurements with kappa = 0.64. CONCLUSIONS: Oral 67Ga Scintigraphy had similar accuracy and agreement compared to colonoscopy in the identification of inflammatory activity in Crohn´s Disease. This new approach may be useful and less invasive for long term follow-ups.

RESUMO RACIONAL Novas terapias revolucionaram o tratamento da Doença de Crohn, mas em alguns países a taxa de cirurgias não se modificou, a frequência de cirurgias de emergência é subestimada e o risco cirúrgico é pouco estudado. OBJETIVOS Analisar fatores de risco e as indicações para cirurgia primária em pacientes com doença de Crohn, em Hospital terciário. MÉTODOS: Análise de banco de dados coletado prospectivamente, de 107 pacientes com doença de Crohn de 2015 a 2021. Os principais desfechos foram a incidência de tratamento cirúrgico, tipos de procedimentos realizados, recidiva cirúrgica, tempo livre de cirurgia e fatores de risco. RESULTADOS: A intervenção cirúrgica foi realizada em 54.2% dos pacientes, sendo a maioria dos procedimentos cirúrgicos de urgência (68.9%). Os procedimentos eletivos (31.1%) foram realizados mais de 11 anos após o diagnóstico. As principais indicações cirúrgicas foram estenose ileal (34,5%) e fístula anorretal (20,7%), sendo o procedimento mais frequente a enterectomia (24,1%). As cirurgias para recidiva foram mais comuns em procedimentos de urgência (OR 2,1; IC95% 1,6-6,6). O fenótipo de comportamento estenosante Montreal L1 (RR = 1,3; IC 95%: 1,0-1,8, p=0,04) e a doença perianal (RR 1,43; IC95% 1,2-1,7) aumentaram o risco de cirurgias de emergência. A regressão linear múltipla mostrou a idade ao diagnóstico como fator de risco para cirurgia (p=0,004). O estudo do tempo livre de cirurgia não mostrou diferença na curva de Kaplan Meier para a classificação Montreal (p=0,73). CONCLUSÕES: Os principais fatores de risco para intervenções cirúrgicas foram estenoses em doenças ileais e jejunais, idade ao diagnóstico, doença perianal e indicações de urgência.
