Long-term brain structure and cognition following bariatric surgery

JAMA Network Open

2024-02-09

(Press-News.org) About The Study: The findings of this study including 133 adults with severe obesity suggest that bariatric surgery was associated with health benefits two years after surgery. Bariatric surgery was associated with improved cognition and general health and changed blood vessel efficiency and cortical thickness of the temporal cortex. These results may improve treatment options for patients with obesity and dementia.

Pioneering technique reveals new layer of human gene regulation

2024-02-09

A technique can determine for the first time how frequently, and exactly where, a molecular event called “backtracking” occurs throughout the genetic material (genome) of any species, a new study shows. Published online February 9 in Molecular Cell, the study results support the theory that backtracking represents a widespread form of gene regulation, which influences thousands of human genes, including many involved in basic life processes like cell division and development in the womb. Led by researchers from NYU Grossman School of Medicine, the work revolves around genes, the stretches ...

Reducing diabetes medication costs can help improve outcomes, especially for low-income patients

2024-02-09

BOSTON, MA — A new study led by researchers at the Harvard Pilgrim Health Care Institute has found that reducing out-of-pocket costs for patients with diabetes, especially those considered low income, can be one step toward improving health outcomes. The study, “Acute Diabetes Complications After Transition to a Value-Based Medication Benefit,” was published in the February 9 edition of JAMA Health Forum. Treatment with antidiabetic agents, antihypertensives, and lipid-lowering ...

Thermal energy storage and the energy transition: MLU coordinates Europe-wide research project

2024-02-09

An international research project led by the Martin Luther University Halle-Wittenberg (MLU) delves into the next generation of seasonal thermal energy storage systems. The "INTERSTORES" project is investigating optimal ways to construct new types of storage systems and integrate them into energy systems. The collaboration between science and industry will receive nearly eleven million euros as part of "Horizon Europe", with around 1.5 million euros going to MLU. The aim is to improve the ...

An anticancer drug opens a new path for the treatment of Parkinson's

2024-02-09

L'Hospitalet de Llobregat, February 8th, 2024. Once they enter the body, drugs, apart from carrying out their therapeutic function, are biochemically transformed by the action of the metabolic machinery, a process that facilitates their expulsion. This biotransformation results in a gradual disappearance of the drug, which is converted into its metabolites. These, in turn, can reach high concentrations in the body and also show a biological activity that may be different from that of the original drug. That is, the metabolites and the drug coexist ...

Innovative coating prevents limescale formation

2024-02-09

Hot water tanks, washing machines, kettles: limescale forms in every domestic appliance that comes into contact with (hot) water – especially in areas where the water is hard, meaning high in calcium. Often the only thing that helps is to use vinegar or a special descaler to dissolve the rock-hard deposits and restore the appliance’s functionality. This is a nuisance in households – and an expensive problem in thermal power stations, for example those that generate electricity, where the formation of limescale is known as fouling. Heat exchangers are particularly prone to limescale, which greatly reduces the efficiency of the systems: ...

Novel technique has potential to transform breast cancer detection

2024-02-09

OAK BROOK, Ill. – An innovative breast imaging technique provides high sensitivity for detecting cancer while significantly reducing the likelihood of false positive results, according to a study published today in Radiology: Imaging Cancer, a journal of the Radiological Society of North America (RSNA). Researchers said the technique has the potential to offer more reliable breast cancer screening for a broader range of patients. Mammography is an effective screening tool for early detection of breast cancer, but its sensitivity ...

Children's Hospital Colorado accepted as one of nine core sites nationally in the prestigious Pediatric Heart Network

2024-02-09

Children’s Hospital Colorado (Children’s Colorado) is announcing its recent acceptance into the Pediatric Heart Network (PHN), a collective of leading hospitals working to improve outcomes and quality of life for children – and more recently adults – with heart disease. The hospital’s Heart Institute will become one of nine clinical research centers across North America selected to be a part of this national network. “We are thrilled to be accepted as a new core site for the Pediatric Heart Network,” said Shelley Miyamoto, MD, professor and Jack Cooper Millisor Chair of Pediatric Cardiology ...

New tumor spatial mapping tool will help clinicians assess aggressiveness of cancer and personalize treatment

2024-02-09

Scientists have developed a new AI tool that maps the function of proteins in a cancerous tumour, enabling clinicians to decide how to target treatment in a more precise way. In cancers such as clear cell renal cell carcinoma (ccRCC), responses to existing treatments are different for each patient, making it difficult to identify the right drug treatment regime for each patient. For example, cancer therapeutic Belzutifan has recently been approved to treat ccRCC, but only has a response rate of 49% in patients with the most common form of the condition. To understand better why some patients respond better than others, researchers from the Universities of Bath and Nottingham studied ...

Certain older Americans show hesitation around brain scan research

2024-02-09

Asian Americans are less likely than their white peers to participate in health research involving MRIs and addressing this hesitancy could improve research, according to a Rutgers Health-led study. Findings by the researchers, published in Alzheimer's & Dementia: Translational Research & Clinical Interventions, a journal of the Alzheimer’s Association, surveyed older adults about their experiences and perceptions of MRI brain imaging scans, their desire to learn results of scans and their attitudes related to dementia and overall research participation. According to the study, South Asian older adults – those 65 and older – are less likely than older white adults ...

Migration solves exoplanet puzzle

2024-02-09

Ordinarily, planets in evolved planetary systems, such as the Solar System, follow stable orbits around their central star. However, many indications suggest that some planets might depart from their birthplaces during their early evolution by migrating inward or outward. This planetary migration might also explain an observation that has puzzled researchers for several years: the relatively low number of exoplanets with sizes about twice as large as Earth, known as the radius valley or gap. Conversely, there are many exoplanets smaller and larger than this size. “Six years ago, a reanalysis of data from the Kepler space telescope revealed a shortage of exoplanets with sizes around ...
