Relapse rare in young men after antireflux surgery
Surgery for severe heartburn has become less common after the turn of the millennium, due in part to the fear of relapse. Instead, most patients are treated with drugs that reduce the acidity of the stomach. However, a new study from Karolinska Institutet in Sweden published in the distinguished journal JAMA shows that the risk of complications and relapse is not as high as feared, especially not in young, healthy males.

Bone marrow-derived cells differentiate in the brain through mechanisms of plasticity
When bone marrow-derived stem cells (BMDCs) were grafted into mutant mice suffering from degeneration of specific neuronal populations at different ages, more bone marrow-derived microglial cells were observed in olfactory bulbs of the test animals where degeneration of mitral cells was still in progress, rather than in the cerebellum where cell degeneration had been completed, showing that BMDCs contribute to the central nervous system variably in the same animal depending on region and cell-specific factors.

How plants manage excess solar energy
Life on earth largely depends on the conversion of light energy into chemical energy through photosynthesis by plants. However, absorption of excess sunlight can damage the complex machinery responsible for this process. Researchers from UNIGE have discovered how Chlamydomonas reinhardtii activates the protection of its photosynthetic machinery. Their study indicates that the receptors that detect ultraviolet rays induce the activation of a safety valve that allows dissipation of excess energy as heat. (2016-12-05)

Study finds cellular processes controlling the formation of lymphatic valves
A mouse model study led by the University of South Florida Health (USF Health) Morsani College of Medicine has identified new cellular processes controlling development of the small valves inside lymphatic vessels, which prevent lymph fluid from flowing the wrong way back into tissues. The new findings suggest that targeting signaling pathways involved in creating and maintaining lymphatic valves may be a viable therapy for patients coping with lymphedema. (2019-08-27)

Now, you can hold a copy of your brain in the palm of your hand
Medical imaging technologies like MRI and CT scans produce high-resolution images as a series of 'slices,' making them an obvious complement to 3D printers, which also print in slices. However, the process of manually 'thresholding' medical scans to define objects to be printed is prohibitively expensive and time-consuming. A new method converts medical data into dithered bitmaps, allowing custom 3D-printed models of patient data to be printed in a fraction of the time. (2018-05-29)

Nicotine patches don't cause heartburn

Irreversible catastrophic brain hemorrhage after minor injury in a patient on dabigatran
Clinicians from the University of Utah report the death of a patient who received a mild brain injury from a ground-level fall while taking the new anticoagulant dabigatran etexilate for non-valve-related atrial fibrillation. Bleeding complications associated with direct thrombin inhibitors, such as dabigatran, are largely irreversible. Physicians should suspect the strong potential for catastrophic hemorrhage in patients taking these medications so that available, albeit limited, management options can be put into effect without delay.

Death rate 70 percent lower at top-rated hospitals: HealthGrades annual hospital quality study
Patients have on average a 70 percent lower chance of dying at the nation's top-rated hospitals compared with the lowest-rated hospitals across 17 procedures and conditions analyzed in the eleventh annual HealthGrades Hospital Quality in America Study, issued today by HealthGrades, the leading independent healthcare ratings organization. Based on the study, HealthGrades today made available its 2009 quality ratings for all nonfederal hospitals in the country at www.healthgrades.com. (2008-10-14)

Real-world heart procedure results consistent with scientific research
The first one-year outcomes data of transcatheter heart valve replacement in nearly all US patients undergoing this procedure shows that real-world outcomes are comparable to or slightly better than those found in clinical trials, according to registry data presented at the American College of Cardiology's 63rd Annual Scientific Session. (2014-03-31)

Ginseng reduces effects of anti-clotting drug
Ginseng, one of the best selling herbal supplements in the United States, interferes with warfarin, a drug commonly used to prevent blood clots. Since precise warfarin dosing is crucial, this can have significant consequences. Too little warfarin can allow clots to form and too much can cause serious bleeding. Anyone who takes both ginseng and warfarin should notify his or her doctor and doctors should ask patients on warfarin if they are taking ginseng. (2004-07-05)

Children with Dravet Syndrome given fenfluramine experienced a greater reduction in convulsive seizures, compared to patients given a placebo for a 14-week treatment period, according to a randomised controlled trial published in The Lancet. (2019-12-17)

Potential RNA Markers of abnormal heart rhythms identified in circulating blood
The irregular heart rhythm atrial fibrillation (AF) increases the risk of stroke and heart failure, but is often undiagnosed because of a lack of symptoms. Now, Tokyo Medical and Dental University (TMDU) researchers have identified four short lengths of RNA (miRNAs) that show increased expression in the circulating blood of AF patients. These miRNAs could be used as potential biomarkers to predict the onset of AF disease. (2018-03-15)

Women can gauge what their fitness level should be at a given age to reduce risk of death
Researchers have developed a nomogram (alignment chart) specifically for women that can be used to predict their expected exercise capacity at any given age, as well as demonstrated that the resulting measure is a predictor of the risk of death. Women whose exercise capacity was less than 85 percent the age-predicted value had twice the risk of death compared to women reaching at least 85 percent. (2005-08-03)

Poor patient warfarin knowledge may increase risk of deadly side effects
