Study Sheds Light on How Mitochondrial Changes Contribute to Muscle Aging

As an individual grows older, they experience continued loss of strength and skeletal muscle mass. Once an adult reaches 40, they start losing roughly 8% of their muscle mass every 10 years. By age 70, this often rises to 15% loss in muscle mass every 10 years. Muscle loss, commonly referred to as sarcopenia, is linked to a heightened risk of disability and mortality in the elderly. It causes frailty, which significantly reduces an individual’s quality of life. While the main cause of sarcopenia isn’t known, researchers posit that mitochondrial dysfunction could help explain its development. Prior studies have determined…

Analysis Reveals Many MA Plans Offer Inadequate Dental Coverage

Traditional Medicare doesn’t cover most dental care, which leaves consumers with the option to enroll in Medicare Advantage that provides dental care as a supplemental benefit. Previous studies have observed high out-of-pocket costs and low dental utilization rates for beneficiaries under traditional Medicare as well as Medicare Advantage. A recent analysis has determined that Medicare Advantage offers poor-quality dental coverage. Only about 8% of plans under this privatized form of Medicare provided dental benefits that met the study's quality standards. A team of researchers from Mass General Brigham conducted the analysis. For their study, the researchers assessed Medicare data from…

Study Uncovers Link Between Gut Infection and Alzheimer’s Disease

Cytomegalovirus is a type of herpes virus that most humans are exposed to in their lives. This virus is normally spread from one individual to another through bodily fluids but isn’t considered a sexually transmitted illness. Prior studies have determined that the virus may remain active in the gut, sometimes travelling to the brain through the vagus nerve. Once there, the virus can alter the immune system and contribute to changes linked to Alzheimer’s. One study found that brains of Alzheimer’s patients were likely to have CD83 microglia, with the researchers noting that antibodies found in the intestines of these…

Researchers Identify Protein That Makes Cancer Evade Cell Therapy

CAR T cell therapy is designed to use the immune system to find and eliminate cancer cells. This therapy is often used to treat types of aggressive blood cancers like lymphoma and leukemia. Prior studies have found that cancer cells have learned how to evade the immune system to avoid elimination. Now researchers at City of Hope have discovered a protein that assists cancer cells in hiding from this treatment. During their study, the researchers discovered that YTHDF2 played a huge role in advancing blood cancer development. The first author of the study, Zhen-Hua Chen, explained that uncovering the biological…

Autism Prevalence Surges Globally, Raising Concerns Among Healthcare Experts

Autism spectrum disorder is a neurodevelopmental disorder that’s characterized by restricted, repetitive and inflexible patterns of interests, activities and behavior. Globally, it is estimated that 61.8 million individuals live with this disorder. Now a new study has highlighted the increase in the prevalence of autism globally, with findings estimating that 1 in 127 individuals are afflicted by the condition. This is quite an increase from previous findings and given that this latest data is from 2021, there’s a possibility the number may be even higher. The study was carried out by the Global Burden of Diseases, with the researchers arguing…

4 Ways of Making e-Commerce Deliveries While Improving City Life

E-commerce and online shopping have grown significantly since the coronavirus pandemic, with choice and convenience pulling in more consumers. It is estimated that by 2027, e-commerce retail sales may have surpassed $8 trillion, representing an increase of about 39%. While this is a good thing, the increasing numbers of delivery vehicles in urban centers aren’t helping fight congestion. A recent paper that examined the growth of delivery culture has found that rising greenhouse gas emissions and traffic congestion as well as health issues may be some of the possible hidden costs linked to deliveries within cities. Given that increased congestion…

IT Professionals Suggest How Healthcare Data Protection Can Be Enhanced

Privacy and security are crucial in any healthcare organization, whether they’re a new practice with growing volumes of records, an established one with vast volumes, or a practice that still hasn’t gone fully digital. While technological advancements can make the lives of both patients and staff easier and ease access to care, they can also make it easier for cybercriminals to breach healthcare systems and obtain sensitive information. This raises the question, how can healthcare organizations ensure the privacy and security of patient data while managing e-health records? Below, we look at some of the ways this can be done,…

Research Shows Brain Tumors Grow by Hijacking Circadian Clocks

Glioblastoma multiforme is an aggressive type of cancer that primarily affects the brain. A new study has found that this cancer has an internal clock which is synced every day to capitalize on the circadian rhythm of the patient. This feature allows tumors to grow as the patient’s body releases hormones. The study, which was carried out by researchers at Washington University in St. Louis, discovered that blocking circadian signals significantly reduced the growth of tumors as well as disease progression. The first author of the study, Maria F. Gonzalez-Aponte, explained that prior studies had allowed the researchers to establish…

New Technology Programs Immune Cells to Combat Brain Cancer, MS

Glioblastoma multiforme is an aggressive type of cancer that usually affects an individual’s spinal cord or brain. Brain cancers, which are among the most difficult cancers to treat, are the primary cause of cancer deaths in kids. The main treatments of this cancer include chemotherapy and surgery, with medications being a less prescribed option as they can’t always access the brain. Now researchers at the University of California-San Francisco have discovered a new way to alter immune cell behavior to attack glioblastoma. For their study, they came up with a molecular GPS that could lead immune cells to the brain…

Why Retirees Should Think Carefully Before Enrolling for Medical Advantage

Retirees have benefited a lot from the Medicare program since its inception in 1965. With the 2025 open enrollment period for the program approaching, some may be thinking about switching to a Medicare Advantage plan. While these plans may appeal to the masses with their low premiums, they aren’t the best choice for every individual. Below, we discuss things retirees need to consider before moving to Medicare Advantage, as well as why they may prefer to remain covered under Original Medicare. So, what should retirees know about Medicare Advantage? For starters, these plans have limited provider networks as they operate…
