Severe Spontaneous Hematomas in Patients Hospitalized with COVID-19.

Objective: To describe the epidemiological, clinical, laboratory, and radiological characteristics, medical treatment, and outcomes of a case series of severe spontaneous hematoma in COVID-19. Material and Methods. This retrospective study included patients hospitalized for COVID-19 who were diagnosed with severe spontaneous bleeding complications by following a standardized treatment protocol that included computed tomography angiography (CTA) from 1 March 2020 to 28 February 2022. The main outcomes were embolization and all-cause mortality. Baseline variables were analyzed for their association with mortality using bivariable logistic regression, and results were expressed as odds ratios (OR) and 95% confidence intervals (CI). Results: In total, 2450 adults were hospitalized for COVID-19 in our center during the study period. 20 patients presented severe and spontaneous intramuscular bleeding (8.1 per 1000 COVID-19 admission vs. 0.47 per 1000 non-COVID-19 admissions, p < 0.001); their median age was 68.5 years (interquartile range (IQR) 63, 80), they had high comorbidity (median Charlson comorbidity index 4.5), and 95% were receiving high doses of heparin. The median interval from COVID-19 symptoms to bleeding was 17 days (IQR 13, 24), and 70% reported cough as a previous symptom. Hypovolemic shock, hypotension, and abdominal pain were the most frequent symptoms of the hematoma. All presented decreased hemoglobin, and 95% required transfusion. Intramuscular hematoma occurred most frequently in the rectus sheath, iliopsoas compartment, and femoral-iliac compartment. All patients underwent embolization; mortality was 45%. We did not identify risk factors associated with an increased risk of death. Conclusion: Although severe bleeding is an uncommon complication of COVID-19, its prevalence is higher than in inpatients without COVID-19, it usually needs embolization, and it is associated with high mortality.

Survey of Carbapenemase-Producing Enterobacteriaceae in Companion Dogs in Madrid, Spain.

We found a low prevalence (0.6%) of carbapenemase-producingEnterobacteriaceae(CPE) in fecal microbiota of companion dogs. A single VIM-1-producingKlebsiella pneumoniaeisolate belonging to sequence type (ST) 2090 was detected.blaVIM-1was carried on a class 1 integron and an untypeable ∼48-kb plasmid. Emergence and spread of CPE in this group of animals may be a threat to public health in human and veterinary medicine. This finding supports the need for active surveillance studies in companion animals that live close to humans, as interspecies transmission may occur within the same household.
