Social groups alleviate depression

Building a strong connection to a social group helps clinically depressed patients recover and helps prevent relapse, according to a new study.

For the paper, Canadian Institute for Advanced Research (CIFAR) Senior Fellow Alexander Haslam, lead author Tegan Cruwys and their colleagues at the University of Queensland conducted two studies of patients diagnosed with depression or anxiety. The patients either joined a community group with activities such as sewing, yoga, sports and art, or partook in group therapy at a psychiatric hospital.

Increased risk of relapse omitting RT in early PET scan negative Hodgkin lymphoma

Interim analysis of the intergroup EORTC-LYSA-FIL 20051 H10 trial published in the Journal of Clinical Oncology indicates an increased risk of early relapse when omitting radiotherapy in early PET scan negative patients with stage I/II Hodgkin's lymphoma. Early outcome, however, was excellent in both arms, and the final analysis should reveal whether these initial findings are maintained over time.

Critical illness increases risk of psychological problems

Fortunately, more and more people survive critical illnesses and accidents. A new Danish-American survey shows, however, that hospitalisation where the patient has received mechanical ventilation can have serious consequences:

- Of course, the good news is that more and more patients survive critical illness and treatment using ventilators. But at the same time, the bad news is that we have now documented that the ventilator patients have a considerable risk of developing psychological problems.

Rush to prescribe: Study questions speed in giving antidepressants to grieving parents

TALLAHASSEE, Fla. — Some doctors are too quick to prescribe antidepressants to parents who have suffered the death of a child either during pregnancy or within the first month of life, according to a study conducted by Florida State University researcher Jeffrey R. Lacasse.

In a study of 235 bereaved parents participating in an online support community, Lacasse found that 88 — or 37.4 percent — of them were prescribed a psychiatric medication to help them cope. Some women received prescriptions with a week of losing their children.

Global attack needed to catch credit thieves

EAST LANSING, Mich. — Stopping massive data breaches like the one that hit Target will require a more sophisticated, collaborative approach by law enforcement agencies around the world, a Michigan State University cyber security expert argues.

Drinking alcohol several times a week increases the risk of stroke mortality

Consuming alcohol more frequently than twice a week increases the risk of stroke mortality in men, according to a study carried out at the University of Eastern Finland. The results show that the effects of alcohol are not limited to the amount consumed, but also the frequency of drinking matters. The results were published in Acta Neurologica Scandinavica on 8 March.

Physical activity and occasional drinking found to be associated with decrease in vision impairment

A physically active lifestyle and occasional drinking is associated with a reduced risk of developing visual impairment, according to a study published online this month in Ophthalmology, the journal of the American Academy of Ophthalmology.

The power of poison: Study examines pesticide poisoning of Africa's wildlife

Poisons are silent, effective and cheap, making the especially dangerous in Africa where they are used for both pest control and illegal poaching. However, as a new study in Annals of the New York Academy of Sciences reveals, they also kill un-intended wildlife.

NHS sight tests lead to waste

Michael Clarke, Consultant Ophthalmologist at Newcastle Eye Centre, says that apart from trauma and orthopaedics, ophthalmology receives more NHS outpatient referrals than any other speciality.

He says that opticians are constrained by legislation to refer patients to a medical practitioner if abnormalities are found at an NHS sight test. However, the testing done at NHS sight tests has become more complex and many patients are now referred with clinically insignificant abnormalities, leading to wastage of appointments in Hospital Eye Services.

Risk of psychiatric diagnoses, medication use increases after critical illness

Critically ill patients receiving mechanical ventilation had a higher prevalence of prior psychiatric diagnoses and an increased risk of a new psychiatric diagnosis and medication use after hospital discharge, according to a study in the March 19 issue of JAMA.

Study examines use of age-adjusted D-dimer levels to exclude lung blood clots

Using a patient's age to raise the threshold for an abnormal result of a blood test used to assess patients with a suspected pulmonary embolism (blood clot in lungs) appeared to be safe and led to fewer healthy patients with the diagnosis, according to a study in the March 19 issue of JAMA.

Ipilimumab in advanced melanoma: Added benefit for non-pretreated patients not proven

The German Institute for Quality and Efficiency in Health Care (IQWiG) already assessed the added benefit of ipilimumab in advanced melanoma in 2012. A considerable added benefit was found for patients who had already received previous treatment. In the new dossier compiled by the drug manufacturer, the drug was now compared with the appropriate comparator therapy dacarbazine specified by the Federal Joint Committee (G-BA) also for non-pretreated patients.

Cardiologists define new heart failure symptom: Shortness of breath while bending over

DALLAS – March 18, 2014 – UT Southwestern Medical Center cardiologists have defined a novel heart failure symptom in advanced heart failure patients: shortness of breath while bending over, such as when putting on shoes.

The condition, which UT Southwestern cardiologists named "bendopnea" (pronounced "bend-op-nee-ah"), is an easily detectable symptom that can help doctors diagnose excessive fluid retention in patients with heart failure, according to the findings published in a recent edition of the Journal of the American College of Cardiology: Heart Failure.

MU study uses video-game device with goal of preventing patient falls

Technology used in video games is making its way to hospital rooms, where researchers at the University of Missouri hope to learn new ways to prevent falls among hospital patients.

Between 700,000 and 1 million people each year fall in U.S. hospitals, according to the Agency for Healthcare Research and Quality. Hospitals nationwide are looking for ways to reduce that number.

An end to animal testing for drug discovery?

DALLAS, March 18, 2014 — As some countries and companies roll out new rules to limit animal testing in pharmaceutical products designed for people, scientists are stepping in with a new way to test therapeutic drug candidates and determine drug safety and drug interactions — without using animals. The development of "chemosynthetic livers," which could dramatically alter how drugs are made, was presented at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.
