La enfermedad grave por coronavirus 2019 (COVID-19) está causada por el Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) y predispone a complicaciones trombóticas. En esta revisión se aborda de manera práctica la estrecha relación entre la tromboembolia venosa y la COVID-19, enfatizando aspectos epidemiológicos, factores de riesgo y tromboprofilaxis, así como potenciales opciones de anticoagulación. Actualmente la evidencia científica es muy escasa, pero día a día seguimos aprendiendo, estando atentos a cambios novedosos y dinámicos en esta enfermedad infecciosa e inmunotrombótica emergente.A finales de 2019, en Wuhan, China, se reportaron numerosos casos de neumonía comunitaria causada por un virus, llamado coronavirus tipo 2 asociado a síndrome respiratorio agudo grave (SARS-CoV-2). En octubre de 2020 rebasamos la preocupante cifra de 34 millones de casos en todo el mundo, con más de 1 millón de decesos. Se han hecho múltiples comparaciones con otras pandemias por coronavirus, y el impacto de la actual es cada vez más desolador.BACKGROUND Tyrosine kinase inhibitors (TKIs) are used to treat metastatic disease associated with clear cell renal cell carcinoma (ccRCC); however, most patients develop resistance after 6 to 15 months. As such, identifying biomarkers of TKI resistance may be useful for prognosis. MATERIAL AND METHODS We analyzed ChIP-seq data related to TKI resistance from the Gene Expression Omnibus and RNA-Seq and clinical data from The Cancer Genome Atlas database. We used univariate Cox analysis and Cox regression/Lasso analysis to determine a risk score. The Kaplan-Meier estimate and receiver operating characteristic curve verified the risk score's sensitivity and specificity. The stratified analysis and the univariate and multivariate analyses revealed its predictive power. We predicted survival time by constructing a nomogram. RESULTS Of the 32 differentially expressed genes (DEGs) related to TKI resistance, 6 (ACE2, MMP24, SLC44A4, C1R, C1ORF194, ADAMTS15) were used to establish a risk score. Kaplan-Meier analysis showed that high-risk patients had shorter median survival times than low-risk patients, notably among those with metastatic disease (1.51 vs. 4.55 years). The stratified analysis revealed that patients with advanced disease had relatively higher risk scores than patients at early stages (P less then 0.001). Univariate analysis independently associated the 6-DEGs signature with the prognosis of metastatic ccRCC (hazard ratio, 1.217; 95% confidence interval, 1.090-1.358). The nomogram we constructed based on 6-DEGs signature and clinical parameters predicted survival time accurately. CONCLUSIONS We identified a 6-DEGs signature that permitted us to establish a risk score related to TKI resistance that can serve as a reliable biomarker for predicting the survival of patients with ccRCC.Infective endocarditis (IE) is an infection of the endocardium and/or heart valves that involves thrombus formation (vegetation). This condition might damage the endocardial tissue and/or valves. An indwelling central venous catheter is a major risk factor for bacteremia at-risked pediatric populations such as premature infants; children with cancer and/or connective tissue disorders. Herbaspirillum huttiense is a Gram-negative opportunistic bacillus that may cause bacteremia and pneumonia rarely in this fragile population. Herein we report the very first case of bacteremia and IE in a pediatric oncology patient caused by H. huttiense.

Imported parasitosis, which do not require an invertebrate vector, are extremely dangerous and can lead to the occurrence of disease in currently parasite free areas. In the present study we report a case of multi-parasitic infection in a young immigrant from Ghana to Italy caused by filaria, Schistosoma sp. and Strongyloides sp.

A 27-year-old Ghanaian man attended the Hospital of Nuoro (Sardinia), Italy, at the end of August 2015, claiming pain to the kidney and hypertensive crisis; the patient presented with dyspnea and epistaxis, chronic itchy skin of the back, shoulders, arms and legs, anuria and high creatinine, metabolic acidosis and hypereosinophilic syndrome. Serological test for parasitic infections were done, and showed a marked positivity for filaria, Schistosoma sp. DNQX supplier and Strongyloides sp. The patient started the treatment immediately with two doses per day of Bassado Antibiotic (tetracycline) for twenty days and then with a single dose of 3 mg of ivermectin that was repeated after 3 months.

Immigrant patients from endemic areas who show clinical signs, such as a general itching on the back, shoulders and arms and legs, should have a thorough history in order to make early diagnosis and prevent further complications. Therefore, general practitioners and doctors in Europe and in other parasitosis non-endemic countries, should consider to test for parasites in any immigrant from endemic countries to aid in establishing the final diagnosis and prevent further complications.

Cytomegalovirus (CMV), is the most common opportunistic infection, remains a cause of life-threatening disease and allograft rejection in liver transplant (LT) recipients. The purpose of this case series is to state that CMV may lead to severe pneumonia along with other bacteria.

CMV pneumonia was diagnosed with the thoracic computed tomography (CT) scan findings, bronchoscopic biopsy, real time quantitative Polymerase Chain Reaction (qPCR) and clinical symptoms. For extraction of CMV DNA from the clinical sample, EZ1 Virus Mini Kit v2.0 (Qiagen, Germany) was used, and aplification was performed with CMV QS-RGQ Kit (Qiagen, Germany) on Rotor Gene Q 5 Plex HMR (Qiagen, Germany) device.

All recipients had severe pneumonia, leukopenia, thrombocytopenia and at least two-fold increase in transaminases on seventh, twenty-eighth and twenty-second days after surgery, respectively. Thoracic CT scan revealed as diffuse interstitial infiltration in the lung parenchyma. Bronchoscopy, Gram-staining and culture from bronchoalveolar lavage (BAL) fluid were performed in all of them.
