Point-of-Care Ultrasound (POCUS) as an Extension of the Physical Examination in Patients with Bacteremia or Candidemia.

BACKGROUND: In general, transthoracic echocardiography (TTE) is the first diagnostic test used for patients with bacteremia or candidemia and clinical signs of Infective Endocarditis (IE). Point-of-care ultrasound (POCUS) may be used in addition to physical examination for the detection of structural heart disease and valve abnormalities. OBJECTIVE: To determine the diagnostic accuracy of POCUS for the detection of signs suggestive of IE, including vegetation, valvular regurgitation, structural heart disease, hepatomegaly, splenomegaly and septic embolisms, in patients with bacteremia or candidemia. DESIGN: Observational, cross-sectional, multicenter study using convenience sampling. SETTING: Six Spanish academic hospitals. PATIENTS: Adult patients with bacteremia or candidemia between 1 February 2018 and 31 December 2020. MEASUREMENTS: The reference test, to evaluate vegetation, valvular regurgitation and structural heart disease, was transesophageal echocardiography (TEE). For patients who did not undergo TEE, transthoracic echocardiography (TTE) was considered the reference test. POCUS was performed by internists, while conventional echocardiography procedures were performed by cardiologists. RESULTS: In 258 patients, for the detection of valvular vegetation, POCUS had sensitivity, specificity, and positive and negative predictive values of 77%, 94%, 82% and 92%, respectively. For valvular regurgitation (more than mild), sensitivity was ≥76% and specificity ≥85%. Sensitivity values for the detection of hepatomegaly and splenomegaly were 92% and 92%, respectively, while those for specificity were 96% and 98%. CONCLUSION: POCUS could be a valuable tool, as a complement to physical examination, at the hospital bedside for patients with bacteremia or candidemia, helping to identify signs suggestive of IE.

Prevalence of bleeding secondary to anticoagulation and mortality in patients with atrial fibrillation admitted with SARS-CoV-2 infection.

Introduction and purpose: Atrial fibrillation (AF) is common in patients admitted with severe COVID-19. However, there is limited data about the management of chronic anticoagulation therapy in these patients. We assessed the anticoagulation and incidence of major cardiovascular events in hospitalized patients with AF and COVID-19. Methods: We retrospectively investigated all consecutive patients with AF admitted with COVID-19 between March and May 2020 in 9 Spanish hospitals. We selected a control group of non-AF patients consecutively admitted with COVID-19. We compared baseline characteristics, incidence of major bleeding, thrombotic events and mortality. We used propensity score matching (PSM) to minimize potential confounding variables, as well as a multivariate analysis to predict major bleeding and death. Results: 305 patients admitted with AF and COVID-19 were included. After PSM, 151 AF patients were matched with 151 control group patients. During admission, low-molecular-weight heparin was the principal anticoagulant and the incidence of major bleeding and mortality were higher in the AF group [16 (10.6%) vs 3 (2%), p = 0.003; 52 (34.4%) vs 35 (23.2%), p = 0.03, respectively]. The multivariate analysis showed the presence of AF as independent predictor of in-hospital major bleeding and mortality in COVID-19 patients. In AF group, a secondary multivariate analysis identified high levels of D-dimer as independent predictor of in-hospital major bleeding. Conclusions: AF patients admitted with COVID-19 represent a population at high risk for bleeding and mortality during admission. It seems advisable to individualize anticoagulation therapy during admission, considering patient specific bleeding and thrombotic risk.

Antecedentes y objetivos: La fibrilación auricular (FA) es frecuente en pacientes ingresados por COVID-19 grave. Sin embargo, los datos sobre el manejo de la anticoagulación crónica en estos pacientes son escasos. Analizamos la anticoagulación y la incidencia de episodios cardiovasculares mayores en pacientes con FA ingresados por la COVID-19. Métodos: Retrospectivamente, se identificaron todos los pacientes con FA ingresados por la COVID-19 entre marzo y mayo de 2020, en 9 hospitales españoles. Se seleccionó un grupo control de pacientes ingresados consecutivamente por la COVID-19 sin FA. Se compararon las características basales, incidencia de hemorragias mayores, episodios trombóticos y mortalidad. Para reducir potenciales factores de confusión se realizó un emparejamiento por puntuación de propensión, así como un análisis multivariante para predecir hemorragia mayor y mortalidad. Resultados: Se incluyeron 305 pacientes con FA ingresados por la COVID-19. Tras el emparejamiento por puntuación de propensión, 151 pacientes con FA fueron emparejados con 151 controles. Durante el ingreso, la heparina de bajo peso molecular fue el principal anticoagulante y la incidencia de hemorragia mayor y mortalidad fue mayor en el grupo de FA (16[10,6%] vs. 3[2%], p = 0,003; 52[34,4%] vs. 35[23,2%], p = 0,03, respectivamente). El análisis multivariante demostró la presencia de FA como predictor independiente de sangrados y mortalidad intrahospitalaria en los pacientes con la COVID-19. En el grupo de FA, un segundo análisis multivariante identificó valores elevados de dímero-D como predictor independiente de hemorragia mayor intrahospitalaria. Conclusiones: Los pacientes con FA ingresados por la COVID-19 representan una población de alto riesgo de sangrado y mortalidad durante el ingreso. Parece recomendable individualizar la anticoagulación durante el ingreso, considerando el riesgo específico de sangrado y trombosis.

Medical sequels of COVID-19.

COVID-19 pandemic has impacted the world population, with a high rate of morbidity and mortality. While the evidence to date has attempted to describe clinical feature of acute illness, recent reports have also begun to describe persistent symptoms that extend beyond the initial period of illness. Adverse outcomes, in addition to respiratory, have been found to occur at different levels: cardiovascular, neurological, or immunological; skin, gastrointestinal or renal manifestations. The detrimental effect on mental health has also been described, not only in COVID-19 patients. The burden of disease secondary to this pandemic is likely to be enormous and not limited to acute disease alone, thus epidemiological studies are needed to further investigate the long-term impact of this disease. This review summarizes the current evidence on short-term effects and describes the possible long-term sequelae of COVID-19.

Se ha encontrado que los resultados adversos, además de respiratorios, se presentan a diferentes niveles: cardiovascular, neurológico o inmunológico; manifestaciones cutáneas, gastrointestinales o renales. También se ha descrito el efecto perjudicial sobre la salud mental, no solo en pacientes con COVID-19. Es probable que la carga de enfermedad secundaria a esta pandemia sea enorme y no se limite únicamente a la enfermedad aguda, por lo que se necesitan estudios epidemiológicos que investiguen más a fondo el impacto a largo plazo de esta enfermedad. Esta revisión resume la evidencia actual sobre los efectos a corto plazo y describe las posibles secuelas a largo plazo del COVID-19.

High-dose corticosteroid pulse therapy increases the survival rate in COVID-19 patients at risk of hyper-inflammatory response.

OBJECTIVE: Test whether high dose corticosteroid pulse therapy (HDCPT) with either methylprednisolone or dexamethasone is associated with increased survival in COVID-19 patients at risk of hyper-inflammatory response. Provide some initial diagnostic criteria using laboratory markers to stratify these patients. METHODS: This is a prospective observational study, 318 met the inclusion criteria. 64 patients (20.1%) were treated with HDCPT by using at least 1.5mg/kg/24h of methylprednisolone or dexamethasone equivalent. A multivariate Cox regression (controlling for co-morbidities and other therapies) was carried out to determine whether HDCPT (among other interventions) was associated with decreased mortality. We also carried out a 30-day time course analysis of laboratory markers between survivors and non-survivors, to identify potential markers for patient stratification. RESULTS: HDCPT showed a statistically significant decrease in mortality (HR = 0.087 [95% CI 0.021-0.36]; P < 0.001). 30-day time course analysis of laboratory marker tests showed marked differences in pro-inflammatory markers between survivors and non-survivors. As diagnostic criteria to define the patients at risk of developing a COVID-19 hyper-inflammatory response, we propose the following parameters (IL-6 > = 40 pg/ml, and/or two of the following: C-reactive protein > = 100 mg/L, D-dimer > = 1000 ng/ml, ferritin > = 500 ng/ml and lactate dehydrogenase > = 300 U/L). CONCLUSIONS: HDCPT can be an effective intervention to increase COVID-19 survival rates in patients at risk of developing a COVID-19 hyper-inflammatory response, laboratory marker tests can be used to stratify these patients who should be given HDCPT. This study is not a randomized clinical trial (RCT). Future RCTs should be carried out to confirm the efficacy of HDCPT to increase the survival rates of COVID-19.

Genetic diversity of HIV in seminal plasma remains higher than in blood after short-term antiretroviral therapy.

OBJECTIVE: To provide insight on viral kinetics and genetic diversity of HIV in seminal plasma at baseline and 1 month after initiating antiretroviral therapy (ART). PATIENTS AND METHODS: Blood and seminal samples from patients with newly diagnosed HIV were obtained before ART initiation (T0) and 1 month after ART initiation (T1). HIV env genetic diversity was studied using deep sequencing Nextera and V3 chemistry in a MiSeq Illumina platform. The number of viral quasispecies (5% cut-off) and Shannon Index were used to analyse diversity. RESULTS: Forty-seven ART-naive patients were recruited between September 2016 and November 2018. At enrolment, the number of quasispecies in blood (median 4 (IQR 2-5)) was lower than in the seminal compartment (median 6, (IQR 4-8)) (p<0.01); the Shannon Index was also higher (p<0.001) in the seminal compartment than in blood (1.77 vs 0.64). At T1, for the 13 patients with detectable HIV in both blood/seminal plasma, viral diversity remained higher (p=0.139) in seminal plasma (median 2 (IQR 1-4.5)) than in blood (median 1 (IQR 1-1.5)) Integrase inhibitors (INI)-based regimens achieved higher levels of undetectability and led more frequently to lower variability (p<0.001) than protease inhibitors (PI) or non-nucleoside reverse transcriptase inhibitors (NNRTI). CONCLUSION: We provide here further evidence of a larger genetic diversity in seminal plasma, both at diagnosis and short term after ART initiation. Our results strengthen previous findings on HIV diversity in seminal plasma. In addition, INIs decrease variability more rapidly than PI and NNRTI in both blood and seminal plasma.

Diagnostic Capacity of Pocket-Sized Ultrasound Devices at Point of Care by a Non-radiologist Resident in Patients with Suspected Abdominal Pathology.

Studies have reported the usefulness and tolerability in practice of abdominal ultrasound performed by non-radiologists in various clinical situations. This prospective observational single-center study included 184 patients hospitalized in an internal medicine department who underwent conventional abdominal ultrasound. A medical resident with basic training performed point-of-care clinical ultrasound using a pocket-sized device. The concordance obtained between the researcher and the radiologist was good (k >0.6) for the gallbladder, splenomegaly, longitudinal diameter of the kidney, presence of renal cysts and hydronephrosis. The specificity was >90% for all parameters assessed except normal renal size. A negative predictive value >90% was obtained for all variables studied except the presence of hepatic space-occupying lesions and gallbladder pathology, the negative predictive values for which were >80%. A positive predictive value >80% was obtained for all of these variables, except the presence of adenopathies, hepatomegaly, space-occupying lesions, echogenicity and/or enlargement of the biliary tract, left renal atrophy and right renal masses. We conclude there was a high concordance between a conventional abdominal study and that performed with a pocket-sized ultrasound device after a brief learning curve.
