Venous thromboembolism (VTE) remains a major cause of morbidity and mortality in hospitalized medically ill patients. These patients constitute a heterogeneous population, whose VTE risk is dependent upon the acute medical illness, immobility status, and patient-specific risk factors that have been incorporated into individualized VTE risk assessment models. Randomized placebo-controlled trials (RCTs) have shown both efficacy and net clinical benefit of in-hospital thromboprophylaxis, which is supported by guideline recommendations. Read More

Patients with coronavirus disease 2019 (COVID-19) have elevated D-dimer levels. Early reports describe high venous thromboembolism (VTE) and disseminated intravascular coagulation (DIC) rates, but data are limited. This multicenter, retrospective study described the rate and severity of hemostatic and thrombotic complications of 400 hospital-admitted COVID-19 patients (144 critically ill) primarily receiving standard-dose prophylactic anticoagulation.

The antiphospholipid syndrome (APS) is an autoimmune systemic disease characterized by a hypercoagulable state secondary to the presence of antiphospholipid antibodies (aPL) and associated to vascular thromboses and/or pregnancy complications. Although ≈60% of thrombotic manifestations is represented by venous thrombosis, also cardiovascular (CV) manifestations can occur in APS patients, comprising coronary and/or non-coronary complications. Moreover, several studies consistently showed a more significant atherosclerosis in APS patients than controls. Read More

The New Coronavirus Epidemic (2019-nCoV), discovered in the city of Wuhan, China, in December 2019, presents mainly with pulmonary pneumonia that is preceded by fever, cough and myalgia. However, as the disease spread globally and the number of hospitalizations increased exponentially, it was noted that most serious patients hospitalized by COVID-19 have laboratory changes worthy of attention, such as lymphopenia, neutrophilia, increased time of prothrombin and increased levels of D-dimer. Due to these changes proving to be crucial for the mortality and morbidity rates in this subset of infected people, several studies focusing on the pathophysiology, mainly hematological, of the disease appear every day.

Background: The relationship between the risk of right heart failure in primary acute pulmonary embolism after embolization and the residual thrombus sites in the pelvis and lower limbs is not clear.

Methods: This single-center retrospective observational study examined the results of contrast-enhanced computed tomography and venous ultrasonography of patients with primary acute PE and DVT. We assessed the association between the occurrence of right heart failure and age; gender; pulmonary thrombosis distribution; most proximal site of deep vein thrombosis in the soleal vein, inferior vena cava (IVC), or common iliac vein (CIV); DVT distribution; and malignancy using univariate and multivariate logistic regression.

Joint Orthopaedic Centre, Sydney, Australia.

Purpose: This study reports the results of a multimodal thromboprophylaxis protocol for lower limb arthroplasty involving risk stratification, intraoperative calf compression, aspirin prophylaxis and early (within 4 h) post-operative mobilisation facilitated by the use of local infiltration analgesia. The study also aimed to identify risk factors for venous thromboembolism (VTE) within a 3-month period following surgery for patients deemed not at elevated risk.

Methods: Patients undergoing knee/hip arthroplasty or hip resurfacing were preoperatively screened for VTE risk factors, and those at standard risk were placed on a thromboprophylaxis protocol consisting of intraoperative intermittent calf compression during surgery, 300 mg/day aspirin for 6 weeks from surgery and early mobilisation.

Fever etiology during the first postoperative days following total knee arthroplasty (TKA) may be challenging to solve. Early periprosthetic joint infection is the main reason; however, other equally important causes must be excluded such as thrombosis, deep venous thrombosis, and chest or urinary tract infections. We report the case of a 70-year-old Caucasian female patient presented with high fever reaching 39°C, fatigue, and myalgia lasting for a week after a fully cemented primary TKA. Read More

Neuromuscular blocking agents (NMBAs) can be an effective modality to address challenges that arise daily in the intensive care unit (ICU). These medications are often used to optimize mechanical ventilation, facilitate endotracheal intubation, stop overt shivering during therapeutic hypothermia following cardiac arrest, and may have a role in the management of life-threatening conditions such as elevated intracranial pressure and status asthmaticus (when deep sedation fails or is not tolerated). However, current NMBA use has decreased during the last decade due to concerns of potential adverse effects such as venous thrombosis, patient awareness during paralysis, development of critical illness myopathy, autonomic interactions, and even residual paralysis following cessation of NMBA use.

Temporary cardiac pacing is commonly used in patients with life-threatening bradycardia and serves as a bridge to implantation of a permanent pacemaker (PPM). For years, passive fixation leads have been used for this purpose, offering the advantage of that they can be placed at bedside. The downside, however, is that patients must remain on telemetry and bed rest until lead removal due to the risk of displacement and failure to capture. Read More

Introduction: Severe thermal trauma to the hand can result in major impairment and reduced function due to defective healing or even extremity loss. Full-thickness injuries frequently incur exposure of tendons or bone and require an early and stable coverage with soft tissue transplants to allow for rapid induction of exercise and to preserve structures and hand function. Free tissue transfer to the hand after thermal trauma is a rare indication, and safety, management, and outcome of free flap surgery for severe acute burn injuries to the hand remains underreported.

Objective: High-value medical care is described as care that leads to excellent patient outcomes, high patient satisfaction, and efficient costs. Neurosurgical care in particular can be expensive for the hospital, as substantial costs are accrued during the operation and throughout the postoperative stay. The authors developed a "Safe Transitions Pathway" (STP) model in which select patients went to the postanesthesia care unit (PACU) and then the neuro-transitional care unit (NTCU) rather than being directly admitted to the neurosciences intensive care unit (ICU) following a craniotomy.
