Pulmonary embolism is the blockage of the blood vessels in the lungs usually due to blood clots from the veins, especially the veins in the legs and pelvis.
Dyspnea, chest pain, syncope or tachypnea (respiratory rate of ≥20/min) occur in most cases of pulmonary embolism.
Pleuritic chest pain with or without dyspnea is one of the most frequent presentations of this disease.
Syncope or shock are the hallmark signs of central pulmonary embolism and usually result in severe hemodynamic repercussions.
Signs of hemodynamic compromise and reduced heart flow are also usually present.
The types of bariatric surgery differentially affect the risk of developing acute pancreatitis postoperatively, such that the risk is greater in patients who undergo vertical sleeve gastrectomy vs Roux-en-Y gastric bypass surgery, according to a study. Risk factors include younger age and presence of gallstones.
An adjuvant trastuzumab treatment course shortened to 9 weeks has failed to demonstrate noninferiority to the standard 1-year course in terms of disease-free survival in breast cancer patients, although the shortened course confers benefits for the risk of severe cardiac toxicity, according to the results of the phase III randomized Short-HER study.
