Testosterone Drugs May Be Overused, FDA Warns
WASHINGTON (AP) — The Food and Drug Administration is warning doctors against over-prescribing testosterone-boosting drugs for men, saying the popular treatments have not been established as safe or effective for common age-related issues like low libido and fatigue. The agency says drugmakers must clearly state in their labeling and promotions that the drugs, currently taken by millions of U.S. men, are only approved to treat low testosterone levels caused by disease or injury, not normal aging. Additionally, the FDA cautioned that the drugs may increase the risk of heart attack, stroke and other cardiovascular problem...

Get the flu vaccine, reduce your risk of death
Last year was a lousy year for the flu vaccine. Hospitalizations for flu hit a nine-year high, and the vaccine prevented flu in only 23% of all recipients, compared with 50% to 60% of recipients in prior years. Why does the flu vaccine work well in some winters and not others? The flu vaccine primes the immune system to attack two proteins on the surface of the influenza A virus, hemagglutinin (H) and neuraminidase (N). Different flu strains have different combinations of these proteins — for example, the strains targeted by recent flu vaccines are H3N2 and H1N1. Unfortunately, the influenza virus is microbiology’s ans...

Thrombolysis-Related Hemorrhage
Intravenous tissue plasminogen activator (tPA) improves outcomes when administered within 4.5 hours of symptom onset of ischemic stroke. Symptomatic intracranial hemorrhage (sICH) is the most feared complication after administration of intravenous tPA. The percentage of patients with a good functional outcome after sICH (as defined by the Safe Implementation of Thrombolysis in Stroke-Monitoring Study) following administration of tPA has been shown to be less than 7%, and mortality rates can be greater than 50%. Almost 2 decades after approval of intravenous tPA by the US Food and Drug Administration, our ability to prevent...

Novel Oral Anticoagulants in Atrial Fibrillation: Update on Apixaban.
Authors: Mezue K, Obiagwu C, John J, Sharma A, Yang F, Shani J Abstract Almost 800,000 new or recurrent strokes happen every year. Atrial fibrillation, the most common cardiac arrhythmia, is a major risk factor for stroke, accounting for 15-20% of ischemic strokes. Apixaban is a direct inhibitor of Factor Xa that was approved in December 2012 by the US Food and Drug Administration (FDA) for the prevention of stroke in patients with non-valvular atrial fibrillation. It is part of a family of novel oral anticoagulants (NOACs) which have the advantage over warfarin of less dosing variability, rapid onset of action and...

Making Sense of Nutraceuticals in China
The Chinese nutraceutical market is considered the third largest in the world after the US and Japan, or the fourth largest if Europe is counted as a single market.Despite strong fundamentals and high rates of annual growth, though, the Chinese market remains some way from realizing its true potential. Its evolution is muddied by ambiguities around what nutraceuticals actually are and how they should be managed.The result has been polarization between over-zealous regulation of so-called health foods, and a grey market where products have skirted approval procedures through questionable positioning or by exploiting alterna...

The streptokinase therapy complications and its associated risk factors in patients with acute ...
Acute myocardial infarction (AMI) is one of the main leading causes of mortality and morbidity. Despite the progress in the treatment of AMI, streptokinase is still being used in many countries. Because of the critical condition of patients with AMI and complications of streptokinase therapy, this study was performed to evaluate the pattern of adverse drug reaction (ADRs) induced by streptokinase and its associated risk factors in patients with acute ST elevation MI. A prospective cross-sectional study in a 14-month period was done at the university affiliated referral cardiovascular center. The Naranjo probability scale a...

Hookah smoking raises cardiovascular risk comparable to traditional cigarette smoking, study finds
This study is believed to be the first to investigate the effects of hookah smoking on stiffening of the arteries. Studies have shown that as cigarette use continues to decline, hookah smoking is rising, especially among youth and particularly among college students.“We know that flavored tobacco products are frequently the first kind of tobacco product used by youth,” Rezk-Hanna said. “One of the major issues with hookah is the fact that the tobacco is flavored with fruit, candy and alcohol flavors, making hookah the most popular flavored tobacco produc t among this audience.”According to the Food and Drug Admini...

YiQi Tongluo Granule against cerebral ischemia/reperfusion injury in rats by freezing GluN2B and CaMK Ⅱ through NMDAR/ERK1/2 Signaling.
This study is aimed to evaluate the protective effect of YQTL on cerebral ischemia reperfusion (I/R) injury and inquire into its underlying mechanisms. Cerebral I/R injury was induced by occluding the middle cerebral artery for 2 h followed by 24 h reperfusion. And regional cerebral flow was monitored by Laser Doppler flow during ischemia phase. The infarct volume was evaluated by Triphenyte-trazolium chloride staining. The protective effects of YQTL were assessed by a number of parameters, including neurological scores, regional cerebral blood flow, pathological changes of neuron in hippocampuses and hippocampus calcium l...

Study: Fish Oil Doesn ’ t Seem To Prevent Heart Problems
This study is consistent with earlier trials. The US Food and Drug Administration approved the fish oil-based drug Vascepa for heart attack and stroke prevention in 2019. Nissen hopes the FDA will take a look at these studies and reconsider that decision. “But it’s hard to get something undone once the genie gets out of the bottle,” he said. An editorial in the journal that accompanies the study written by Dr. Gregory Curfman, assistant professor of medicine at Harvard Medical School, also suggested the FDA should require a postmarketing clinical trial of a high-dose of fish oil, such as Vascepa, vs. corn...

Assessing the Health and Economic Impact of a Potential Menthol Cigarette Ban in New York City: a Modeling Study
AbstractMenthol in cigarettes increases nicotine dependence and decreases the chances of successful smoking cessation. In New York City (NYC), nearly half of current smokers usually smoke menthol cigarettes. Female and non-Latino Black individuals were more likely to smoke menthol-flavored cigarettes compared to males and other races and ethnicities. Although the US Food and Drug Administration recently announced that it will ban menthol cigarettes, it is unclear how the policy would affect population health and health disparities in NYC. To inform potential policymaking, we used a microsimulation model of cardiovascular d...

Performing Transcatheter Left Atrial Appendage Closure: Techniques and Challenges
The left atrial appendage (LAA) has been demonstrated to be the major source of thromboemboli in patients with atrial fibrillation (AF).1 The rationale of LAA closure is based on eliminating LAA continuity with the left atrium thereby reducing stroke risk. Indeed, left atrial appendage occlusion (LAAO) procedures play an important role in anticoagulation-intolerant patients at risk for AF-related stroke. Based on the PROTECT-AF2 and PREVAIL3 studies, the Food and Drug Administration (FDA) approved use of the Watchman (Boston Scientific, MA) device in 2015, with an updated generation of device subsequently ratified in 2020 ...
