A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Studies suggests that insular cortex may hold key to treating addiction

A pair of studies suggests that a region of the brain - called the insular cortex - may hold the key to treating addiction. Scientists have come to this conclusion after finding that smokers who suffered a stroke in the insular cortex were far more likely to quit smoking and experience fewer and less severe withdrawal symptoms than those with strokes in other parts of the brain.

14th APS symposium highlights role of endothelin in many biological functions

Endothelin (ET) is a peptide produced by cells in the blood vessels and has powerful vessel-constricting effects. Although endothelin is mainly associated with its role in blood pressure control and cardiovascular diseases, it continues to appear in other physiological functions and diseases.

TXA drug reduces blood transfusion, saves costs

Using an inexpensive drug for every hip or knee replacement since 2013 has helped St. Michael's Hospital reduce its number of red blood cell transfusions performed during these surgeries by more than 40 per cent without negatively affecting patients, according to new research.

Free e-book provides advice for lowering breast cancer risk at every stage of life

Surprisingly, preventing breast cancer can begin as early as age 2. Eating right, being physically active and keeping weight in check - even at a young age - can substantially lower breast cancer risk.

HBV DNA levels guide antiviral treatment in chemotherapy setting

Pretreatment levels of hepatitis B virus DNA could inform the withdrawal of pre-emptive antiviral therapy in chronic HBV patients undergoing cytotoxic chemotherapy for cancer, indicate research findings published in Digestive Diseases and Sciences.

Risk score predicts ACLF risk in chronic HBV patients

A risk score incorporating routinely collected clinical information can identify patients with chronic hepatitis B virus infection at high risk of developing acute-on-chronic liver failure following severe acute exacerbation, research suggests.

Study: High school athletes use smokeless tobacco at a higher rate compared to non-athletes

High school athletes who play on sports teams smoke tobacco products at a lower rate than non-athletes, but use smokeless tobacco at a higher rate, according to a study published by the Centers for Disease Control and Prevention in today's Morbidity and Mortality Weekly Report (MMWR).

Research findings may help explain why drug treatments for addiction, depression are not always effective

New research may help explain why drug treatments for addiction and depression don't work for some patients. The conditions are linked to reward and aversion responses in the brain. Working in mice, researchers at Washington University School of Medicine in St. Louis have discovered brain pathways linked to reward and aversion behaviors are in such close proximity that they unintentionally could be activated at the same time.

Diabetes may be linked to buildup of brain tangles associated with Alzheimer’s disease

Diabetes may be linked to the buildup of tangles or tau in the brain, separate from Alzheimer's disease, according to a new study published in the September 2, 2015, online version of Neurology, the medical journal of the American Academy of Neurology.

Boca Raton Regional Hospital introduces ultra-minimally invasive procedure for patients with atrial fibrillation

Boca Raton Regional Hospital's Richard G. Cartledge, MD, FACS, has begun performing ultra-minimally invasive left atrial appendage ligation for atrial fibrillation patients who are on anticoagulants such as Coumadin, Xarelto or Effient. Dr. Cartledge, who is Chief of Cardiothoracic Surgery at the Hospital, is one of a select group of surgeons nationally using this method, which involves making two microscopic incisions in order to seal off the left atrial appendage (LAA) in patients where anticoagulants are contraindicated or who refuse to be on such medications.

Prime Healthcare Services acquires St. Joseph Mercy Port Huron

Prime Healthcare Services, the fastest growing hospital system in the nation, announced today that it has completed the acquisition of St. Joseph Mercy Port Huron. As a result, St. Joseph Mercy Port Huron will now be known as Lake Huron Medical Center.

Elevated blood pressure associated with increased risk of ICH recurrence

Survivors of an intracerebral hemorrhage (ICH; a type of hemorrhagic stroke in which bleeding occurs directly into the brain) who had inadequate blood pressure (BP) control during follow-up had a higher risk of ICH recurrence, with this association appearing stronger with worsening severity of hypertension, according to a study in the September 1 issue of JAMA.

New NIH grants support research that combines DNA sequence information and electronic medical records

A dozen awards from the National Institutes of Health will support research that incorporates DNA sequence information into electronic medical records. The goal of research conducted by the Electronic Medical Records and Genomics (eMERGE) network is to better understand the genomic basis of disease and to tailor medical care to individual patients based on their genomic differences.

Common antidepressant can help stroke patients improve movement and coordination

Working with mice, researchers at Johns Hopkins have added to evidence that a commonly prescribed antidepressant called fluoxetine helps stroke victims improve movement and coordination, and possibly why.

First-line catheter ablation treatment superior to drug therapy for suppressing AF

First-line treatment with catheter ablation is superior to drug therapy for reducing atrial fibrillation, according to five year results from the MANTRA-PAF trial presented for the first time at ESC Congress today.

European cardiomyopathies registry shows higher than expected use of defibrillators, genetic testing

The most representative snapshot of real world practice in cardiomyopathies in Europe has shown a higher than expected use of defibrillators and genetic testing. The baseline results of the ESC's EORP Cardiomyopathy Registry Pilot are presented for the first time today at ESC Congress 2015.

Report: 3 out of 4 U.S. adults have hearts older than their actual age

Your heart may be older than you are – and that's not good. According to a new CDC Vital Signs report, 3 out of 4 U.S. adults have a predicted heart age that is older than their actual age. This means they are at higher risk for heart attacks and stroke.

AF patients treated with rivaroxaban for stroke prevention experience low rates of bleeding and stroke

Atrial fibrillation (AF) patients treated with rivaroxaban for stroke prevention have low rates of bleeding and stroke, reveals real-world data from the XANTUS study presented at ESC Congress today.

Amgen, Novartis collaborate for Alzheimer's disease and migraine programs

Amgen today announced a neuroscience collaboration with Novartis in the areas of Alzheimer's disease and migraine. The collaboration accelerates Amgen's potential entry into Alzheimer's disease by teaming up with Novartis on a differentiated and genetically validated Alzheimer's disease program directed at genetically predisposed individuals at risk of developing Alzheimer's disease.
