Mar 11th, 2019 - Barotrauma is physical tissue damage caused by a pressure difference between an unvented space inside the body and surrounding gas or fluid. The damage is due to shear or overstretching of tissues. As a gas-filled space expands or contracts, it can cause damage to the local tissue. Occasionally, tears in tissue can allow gas to enter the body through the initial trauma site. This causes potenti...

Mar 1st, 2019 - Nitroglycerin is a vasodilatory drug that is used primarily to provide relief from anginal chest pain. Nitroglycerin has been FDA approved since 2000 and was first sold by Pfizer under the brand name Nitrostat. It is currently FDA approved for the acute relief of an attack or acute prophylaxis of angina pectoris secondary to coronary artery disease. Off-label, non-FDA approved uses include trea...
Dec 31st, 2010 - Acute chest pain is a frequent presenting complaint in emergency departments. Along with other important disease entities such as aortic dissection and pulmonary embolus, such patient symptoms may question the possibility of acute myocardial ischemia. Acute coronary syndromes (ACS) include ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina (UA) . B...

Dec 11th, 2006 - The importance of resting heart rate (HR) as a prognostic factor and potential therapeutic target is not yet generally accepted. Recent large epidemiologic studies have confirmed earlier studies that showed resting HR to be an independent predictor of cardiovascular and all-cause mortality in men and women with and without diagnosed cardiovascular disease. Clinical trial data suggest that HR re...

Aug 30th, 2006 - Rene Theophile Hyacinthe Laënnec (1781–1826) was a French physician who, in 1816, invented the stethoscope. Using this new instrument, he investigated the sounds made by the heart and lungs and determined that his diagnoses were supported by the observations made during autopsies. Laënnec later published the first seminal work on the use of listening to body sounds, De L’auscultation Mediate (O...
Sep 11th, 2019 - The US Food and Drug Administration (FDA) has cleared an artificial intelligence (AI) algorithm from GE Healthcare that analyzes chest x-rays for pneumothorax and helps flag suspected cases for radiologists to prioritize reading, the company announced today. The algorithm, part of a set of other quality-assurance algorithms named the Critical Care Suite, was developed to run on a GE Healthcare ...
Jun 21st, 2019 - NEW YORK (Reuters Health) - New research helps zero in on which patients with suspected coronary artery disease (CAD) will derive the most benefit from coronary computed tomography angiography (CTA). "Our results indicate that the accuracy of coronary CTA is highest for clinical decision making if probability of coronary disease is between 7% and 67%," lead authors Dr. Robert Haase and Dr Marc ...
Jun 18th, 2019 - After a diagnosis of myocardial infarction (MI) or angina pectoris, individuals enrolled in the English Longitudinal Study of Aging (ELSA) showed more accelerated cognitive decline than those who remained free of coronary heart disease (CHD). The findings, published in the June 25 issue of the Journal of the American College of Cardiology, also showed that the cognitive deterioration occurred n...
Jun 17th, 2019 - TEL AVIV (Reuters) - Zebra Medical Vision, an Israel medical imaging analytics company, said on Monday it received its third clearance from the U.S. Food and Drug Administration for its alert for intracranial hemorrhage, based on head CT scans. The latest cleared product uses artificial intelligence to automatically identify suspected internal brain bleeds based on head CTs. This can significan...

Jun 3rd, 2019 - No. After thoracentesis, chest radiography or another lung imaging study should be done only if pneumothorax is suspected, if thoracentesis requires more than 1 attempt, if the patient is on mechanical ventilation or has pre-existing lung disease, or if a large volume (> 1,500 mL) of fluid is removed.

May 18th, 2019 - In patients with tumors bordering the central airway, use of antiangiogenic agents has been linked to fatal hemorrhage after radiation treatment, according to investigators reporting a large, retrospective case series. Most hemorrhagic events in these patients with so-called “ultracentral” lung tumors occurred in those who received bevacizumab or pazopanib within 30 days of stereotactic body ra.

May 14th, 2019 - Women undergoing open descending thoracic aortic aneurysm (DTA) and open thoracoabdominal aortic aneurysm (TAAA) repair are not at greater risk for operative mortality than their male counterparts. However, they are at significantly greater risk for major adverse events and have significantly lower 5-year survival, according to the results of a single institution database review of 738 surgery.
May 13th, 2019 - TEL AVIV (Reuters) - Israel’s Zebra Medical Vision said on Monday it received approval from the U.S. Food and Drug Administration for its artificial intelligence-based chest X-ray triage product. The FDA approval focuses on an alert for urgent findings of pneumothorax, which the company said has demonstrated potential to reduce turnaround time and increase the radiologist’s confidence in making...
Apr 21st, 2019 - (Reuters Health) - In many parts of the world there are not enough radiation oncologists to design and deliver radiation treatments for lung cancer patients, but that gap could one day be filled with the help of artificial intelligence, researchers suggest in a new study. In a novel approach to the problem, the authors turned to crowdsourcing to help them develop a computer algorithm that would...

Apr 4th, 2019 - EVIDENCE SUMMARY A 2017 meta-analysis of 16 RCTs examined the risk of cardiovascular events in 7540 adult patients taking PPIs for GERD (mean ages 45-55 years). 1 The primary outcome was cardiovascular events—including acute myocardial infarction, myocardial ischemia, angina pectoris, cardiac failure, and coronary artery stenosis—and cardiac disorders.
Mar 18th, 2019 - The Society for Vascular Surgeons and the Society for Thoracic Surgeons are seeking comments on draft Reporting Standards for Type-B Aortic Dissection. Reports focusing on type-B aortic dissection have become increasingly common in recent years, but there is currently no guidance for investigators on reporting.
