Deep vein thrombosis (DVT) is part of the clinical spectrum of venous thromboembolism disease (VTE), whose estimated annual incidence rate is 1-2 episodes per 1000 individuals and represents the third leading cause of cardiovascular mortality in developed countries. Establishing an accurate diagnosis of DVT is essential for preventing acute complications (such as pulmonary embolism) and chronic complications associated with post-thrombotic syndrome. Currently, there are well-established diagnostic algorithms for lower extremity DVT, which include clinical probability models that help establish the risk of experiencing the disease based on the patients' history, clinical findings, D dimer measurements, fibrin degradation product tests with a high negative predictive value and imaging tests to confirm the diagnosis. ⋯ The consensus is not as clear about the need for a proximal or complete examination of the entire extremity. Other techniques may also be employed, such as magnetic resonance venography and venous phase computed axial tomography, although these should not be a substitute for compression ultrasonography as the initial diagnostic test. There are other special circumstances in which the diagnosis is more problematic and there are no diagnostic algorithms as consolidated, such as DVT during pregnancy, diagnosing rethrombosis and DVT that affects the upper extremities.

Comorbidity and prognostic factors on admission in a COVID-19 cohort of a general hospital.
To describe clinical features, comorbidity, and prognostic factors associated with in-hospital mortality in a cohort of COVID-19 admitted to a general hospital. ⋯ The presence of cardiopathy, levels of LDH≥345IU/L and age ≥65 years are associated with a higher risk of death during hospital stay for COVID-19. This model should be validated in prospective cohorts.

Despite the potential benefits of outpatient care, most patients with pulmonary embolisms are treated in hospitals for fear of possible adverse events. However, there is a wealth of scientific evidence from studies covering more than 4000 outpatients, which has led the current clinical practice guidelines to recommend early discharge or outpatient treatment when a low risk of death or complications has been confirmed, when there are no comorbidities or aggravating processes present to warrant hospitalisation and when appropriate monitoring and treatment are observed. ⋯ Using these tools, the short-term outcomes (30-90days) show low mortality (in general <3%) and a low incidence of other complications (rate of recurrence and major bleeding <2%). Based on the available evidence, outpatient treatment can be considered the most appropriate strategy at this time for most hemodynamically stable patients with pulmonary embolisms.

ReviewProphylaxis of venous thromboembolism disease in patients with cancer.
Thrombotic risk should always be assessed in the various clinical scenarios of patients with cancer. Thromboprophylaxis with low-molecular-weight heparin is recommended above other anticoagulants for most patients with cancer who are hospitalised. However, the safety of primary thromboprophylaxis in this context is unknown; however, thromboprophylaxis can be completed with mechanical methods. ⋯ In these cases, prophylaxis such as apixaban, rivaroxaban and low-molecular-weight heparin may be employed, provided there are no significant risk factors for bleeding or drug interactions. In patients undergoing oncologic surgery, thromboprophylaxis should be started before the surgery, continuing for at least 7 to 10 days and, in cases of major surgery, even up to 4 weeks. Drug prophylaxis is not routinely recommended to prevent upper extremity thrombosis in patients who carry central venous catheters.
