The Role of Heparin in Postural Orthostatic Tachycardia Syndrome and Other Post-Acute Sequelae of COVID-19.

The therapeutic management and short-term consequences of the coronavirus disease 2019 (COVID-19) are well known. However, COVID-19 post-acute sequelae are less known and represent a public health problem worldwide. Patients with COVID-19 who present post-acute sequelae may display immune dysregulation, a procoagulant state, and persistent microvascular endotheliopathy that could trigger microvascular thrombosis.

Postural orthostatic tachycardia syndrome and other related dysautonomic disorders after SARS-CoV-2 infection and after COVID-19 messenger RNA vaccination.

The COVID-19 pandemic has caused a challenge for our society due to the post-acute sequelae of the disease. Persistent symptoms and long-term multiorgan complications, known as post-acute COVID-19 syndrome, can occur beyond 4 weeks from the onset of the COVID-19 infection. Postural orthostatic tachycardia syndrome (POTS) is considered a variety of dysautonomia, which is characterized by chronic symptoms that occur with standing and a sustained increase in heart rate, without orthostatic hypotension.

[Prophylaxis of venous thromboembolism in orthopedic surgery. Role of the new anticoagulants].

Patients undergoing a total hip or total knee arthroplasty are at high risk of thromboembolism in the postoperative period and after hospital discharge; consequently, clinical guidelines recommended thromboprophylaxis for 10-35 days. Although improved surgical techniques and widespread use of anticoagulants have substantially reduced the incidence of thromboembolic events, venous thromboembolic disease is still a dangerous complication and, in these patients, pulmonary embolism remains the main cause of death. Low molecular weight heparins have long been the mainstay of prevention.

[Assessment of venous thromboembolism risk in hospitalized medical patients. Concordance between PRETEMED guide and the recommendations of the viii conference of the American College of Chest Physicians].

Background And Objective: The aim of this study is to evaluate the use of venous thromboembolism prophylaxis in hospitalized medical patients using 2 clinical practice guidelines and to analyze the agreement between them.

Patients And Methods: Cross-sectional study of medical services in a third level hospital. We calculated the thromboembolic risk and the thromboprophylaxis adequacy by implementing the recommendations of viii conference of the American College of Chest Physicians (ACCP) and PRETEMED guide as well as their agreement.

Why not use the HbA1c as a criterion of dysglycemia in the new definition of the metabolic syndrome? Impact of the new criteria in the prevalence of the metabolic syndrome in a Mediterranean urban population from Southern Europe (IMAP study. Multidisciplinary intervention in primary care).

We analysed the prevalence of metabolic syndrome (MS) of the new diagnostic criteria and the HbA1c to diagnose dysglycemia. We studied 2006 adults without cardiovascular disease or diabetes. The use of the new criteria and the HbA1c resulted in an increase in the population prevalence of MS.

Benign symmetric lipomatosis of the tongue in Madelung's disease.

Introduction: Madelung's disease is characterized by benign, non-encapsulated accumulations of fat in a symmetrical manner. Although rare, symmetrical lipomatosis involving the tongue exclusively has been previously reported. Here another case is presented of Madelung's disease involving the tongue.
