Genotype matters—tailored screening for germline CHEK2 variants

A recent editorial was published in Oncotarget, titled “Genotype matters: Personalized screening recommendations for germline CHEK2 variants.” Recognized as a moderate-risk gene, CHEK2—responsible for encoding the CHK2 protein, which plays a crucial role in the repair of DNA double-strand breaks—is associated with a 20–40% lifetime risk of breast cancer (BC) by age 85. While CHEK2 pathogenic variants (PVs) were previously linked to an increased risk of colorectal cancer (CRC), two recent studies have not observed this association. In their recent work, researchers Adela Rodriguez Hernandez, Rochelle Scheib, Judy E. Garber, Huma Q. Rana and Brittany L. Bychkovsky from Dana-Farber Cancer Read More

New device monitors levels of inflammation-associated C-reactive protein in real time

Graphical abstract. Credit: ACS Sensors (2024). DOI: 10.1021/acssensors.4c00249 As inflammation is the body’s natural immune response to disease or infection, it increases blood flow in the body and helps the body’s cells to defend themselves against viruses, infections or cell damage. Fast diagnostics of inflammation is crucial for effective treatments, so it is extremely important to test the levels of inflammatory biomarkers in the body. Researchers from the Institute of Physical Chemistry, Polish Academy of Sciences have demonstrated a novel point-of-care device to monitor levels of the C-reactive protein (CRP) that is produced in the body during inflammation.

Knowing you have a brain aneurysm may raise risk of anxiety, other mental health conditions

Among people who had aneurysms (weakened areas in brain blood vessels), the risk of developing a mental health condition was higher than among peers without an aneurysm. The highest risk was seen in patients younger than age 40, according to research published in Stroke. An unruptured intracranial aneurysm occurs when the wall of a blood vessel in the brain becomes weak and bulges out, posing a potential risk of future rupture and life-threatening bleeding in the brain. “As a neurosurgeon who treats cerebral aneurysms, I often see people who do not undergo surgery yet feel fear and/or anxiety about their Read More

Comprehensive review identifies three key concepts for recovery from substance use disorders

Certain concepts have a demonstrated basis for aiding recovery from dangerous alcohol or substance use, according to an analysis of scientific literature since 1990. Self-efficacy (a belief in one’s ability to achieve a goal), social support, and managing cravings are among the treatment elements best supported by evidence. Effective treatment for alcohol use disorder (AUD) and other substance use disorders (SUDs) depends on understanding how human behaviors change and incorporating that knowledge into clinical practice. An ongoing research effort continues to investigate varying treatment approaches and how they relate to recovery outcomes, but those findings have not been well synthesized Read More

Is white rice bad for me? Can I make it lower glycemic index or healthier?

Rice is a culinary staple in Australia and around the world. It might seem like a given that brown rice is healthier than white and official public health resources often recommend brown rice instead of white as a “healthy swap.” But Australians definitely prefer white rice over brown. So what’s the difference, and what do we need to know when choosing rice? What makes rice white or brown? Rice “grains” are technically seeds. A complete, whole rice seed is called a “paddy,” which has multiple parts: the “hull” is the hard outer layer which protects the seed the “bran,” which Read More

Physician shares four ideas for avoiding the ‘freshman 15’

Credit: Helena Lopes from Pexels The term “freshman 15” often refers to weight gain by students during their first year in college. Many times, it’s their first time away from home and their normal routines. Dr. Denise Millstine, a Mayo Clinic internal medicine physician, shares daily goals for every freshman. In this season of packing up for college, here’s a warning about packing on the “freshman 15.” “It’s usually not actually 15 (pounds). It’s more often 7 or 8,” says Dr. Millstone. Still, it’s extra weight that Dr. Millstine says is often caused by a change in activity and eating Read More

Inside the political fight to build a rural Georgia hospital

Ed Whitehouse stood alongside a state highway in rural Butts County, Georgia, and surveyed acres of rolling fields and forests near Interstate 75. Instead of farmland and trees, he envisioned a hospital. Whitehouse, a consultant for a local health care company that wants to build a hospital there with at least 150 beds, said the group could break ground within a year. The idea, he said, is to provide medical services beyond those currently provided by Wellstar Sylvan Grove Medical Center, an aging, nonprofit “critical access” hospital that offers limited services, including emergency care, rehabilitation, wound care, and imaging. But Read More

Insurance coverage could impact survival of patients after spinal cord injury

The care of people seriously harmed by spinal cord injury can cost hundreds of thousands of dollars, and a new analysis suggests that ability to pay influences how long a patient remains on life support. In a study of more than 8,400 U.S. adults with severe spinal cord injury, “uninsured patients had greater odds of withdrawal of life-supporting treatment,” compared to those who had private insurance, researchers said. The findings were published in the journal JAMA Surgery. According to background information in the study, an estimated 1.3 million people in North America have been affected by a spinal cord injury, Read More

Structural racism in neighborhoods linked to risk of cancer from traffic-related air pollution

High levels of traffic-related air pollutants have been linked with elevated risks of developing cancer and other diseases. New research indicates that multiple aspects of structural racism—the ways in which societal laws, policies, and practices systematically disadvantage certain racial or ethnic groups—may contribute to increased exposure to carcinogenic traffic-related air pollution. The findings are published in the journal Cancer. Most studies suggesting that structural racism, which encompasses factors such as residential segregation and differences in economic status and homeownership, may influence neighborhood exposures to air pollutants have focused on residential racial segregation, which is only one indicator of structural racism.

Survey finds more than 3 in 4 Americans don’t feel they could help someone suffering an opioid overdose

International Overdose Awareness Day is a worldwide campaign held each Aug. 31 that acknowledges the grief of family and friends left behind from those who have died from a drug overdose. This year’s campaign theme “Together we can” highlights the power of the community standing together to help end overdose. However, a new survey of 1,000 Americans from The Ohio State University Wexner Medical Center and College of Medicine found more than three in four Americans say they would not be able to step in to treat an overdose. “A recent Ohio State survey found that 77% of people are Read More

A case of tick-borne Powassan virus in a child

With tick-borne viruses such as Powassan virus increasing in Canada, clinicians should consider these infections in patients with encephalitis, as a case study shows in the Canadian Medical Association Journal. Although rare, Powassan virus is serious, with a death rate of 10–15% in people with encephalitis, and it can cause lingering health effects after infection. The virus can transmit within 15 minutes of tick attachment, and symptoms can develop one to five weeks later. In this case study, a 9-year-old child with up-to-date vaccinations was admitted to hospital after a visit to an emergency department for fever, neck stiffness, and Read More

People of lower socioeconomic status less likely to receive cataract surgery in private clinics, research shows

Despite increased funding for cataract surgeries to private, for-profit clinics, access to surgery fell 9% for lower-income people, according to new research published in the Canadian Medical Association Journal. “Unexpectedly, despite new public funding for operations provided in private for-profit surgical centers, which was intended to fully cover all overhead costs and remove the need to charge patients, this disparity did not decrease, but instead grew during the funding change period,” says lead author Dr. Robert Campbell, a clinician–scientist in the Department of Ophthalmology at Queen’s University and a senior adjunct scientist at ICES.

A study finds an increased risk of developing a productive SARS-CoV-2 infection in obese people. Obesity is known to predict worse outcomes and higher mortality for those with COVID-19. Masanori Aikawa and colleagues sought to determine if obesity also affected the likelihood of getting ill in the first place. The article is published in PNAS Nexus. To investigate, the authors analyzed electronic medical records for 687,813 patients from the Mass General Brigham health care system, including 72,613 individuals with suspected SARS-CoV-2 exposure, 18,447 of whom tested positive. The authors limited their data to a timeframe before vaccination became widespread in Read More

Mpox global emergency not an imminent threat in US, expert says

While the World Health Organization declares mpox a global emergency based on rapid spread in African countries, the infectious disease formerly known as monkeypox has been considered an epidemic in the U.S. since 2022. Dr. Kevin Dieckhaus, chief of UConn Health’s Division of Infectious Diseases, has been keeping an eye on it, both here and overseas. “At this point there is no cause for great alarm,” Dieckhaus says. “Our local epidemic is not from the strain that led to the WHO declaration of a public health emergency of international concern. At this time, the concern in Africa is due to Read More

Ohio study reveals high risk of overdose deaths among those using drugs when they’re alone

In Cuyahoga County, the stark reality of the opioid crisis is that most drug overdose victims die alone, with no one nearby to help. A recent study, done in partnership with Case Western Reserve University and Cuyahoga County, highlights the critical need for “targeted harm-reduction strategies” in Northeast Ohio, where the opioid epidemic continues to claim lives at nearly twice the national average. The paper is published in the journal Substance Use & Misuse. Those strategies include the distribution of Naloxone (an opioid antagonist that can reverse the effects of an overdose), and increasing the availability of medication-assisted treatment options Read More

Study finds females have lower salivary flow than males before and after radiation therapy for head, neck cancer

Reduced salivary flow, or hyposalivation, can cause an increased risk for tooth decay and other mouth conditions. Measuring salivary flow is important to guide risk assessment and management strategies when treating patients with oral health diseases. Typically, the same standard normal values are used for both females and males in interpreting results of salivary flow testing. A recent publication led by Dr. Rajesh Lalla, professor and associate dean for research at the UConn School of Dental Medicine, took a deeper look at differences in salivary flow between female and male patients before and after radiation therapy for head and neck Read More

New study reveals key to long-term vaginal microbiome balance with just a few samples

Credit: Ina Schuppe Koistinen, Karolinska Institutet A new study published in Microbiome by researchers at Karolinska Institutet, suggests that a few well-timed samples could help predict long-term imbalances in vaginal health, which is linked to various health issues. The vaginal microbiome fluctuates during the menstrual cycle, with some women maintaining balance while others shift toward imbalance. This study tracked 49 women daily through a cycle using metagenomic sequencing, identifying four Vaginal Community Dynamics (VCDs): constant eubiotic, constant dysbiotic, menses-related, and unstable dysbiotic. Higher bacteriophage levels and specific bacterial genes were linked to instability. The study suggests that just a few Read More

Finding epilepsy hotspots before surgery: A faster, non-invasive approach

Neurosurgery for patients with drug-resistant epilepsy requires locating the precise brain areas that are generating the seizures. Typically, patients undergo seven to 10 days of invasive intracranial EEG monitoring, with electrodes surgically implanted inside the brain through one or more skull openings to capture seizure activity as it happens. Eleonora Tamilia, Ph.D., directs the Epilepsy Monitoring Unit Signal and Data Science Program within the Epilepsy Center at Boston Children’s Hospital. Her team has piloted a much briefer method for mapping seizure zones. Not only is it noninvasive, but can it provide information a traditional EEG reading cannot. It combines standard Read More

The Mediterranean diet is all the rage because it represents a way of life we’ve lost

The promise of a long, healthy, happy existence living an active, community-based lifestyle under warm, sunny skies may be within reach. In fact, it could be on your table. The Mediterranean diet has been included on UNESCO’s Intangible Cultural Heritage list since 2010. Not only does the diet have guaranteed cultural value, it is also a powerful strategic tool for promoting food products such as olive oil. Often cited for its health benefits, the Mediterranean diet was first described in a 1953 book about Crete. At the time, people were amazed at the low incidence of cardiovascular disease among the Read More

Personalized brain stimulation significantly decreases depression symptoms in pilot study

Credit: Wikimedia Commons In a small pilot study, UNC School of Medicine researchers led by Flavio Frohlich, Ph.D., used a new closed-loop system to measure the electrical brain patterns of individual patients and then stimulate those patterns with a weak electrical current, resulting in significantly improved symptoms of major depressive disorder. Our brains are full of electricity, billions of signals being sent each day whether we’re exercising, eating, singing, reading, working, sleeping, or just relaxing. And when we’re sitting with our thoughts—awake with our eyes closed—particular electrical patterns at 8–12 Hz dominate our brains. They are called alpha oscillations. In Read More

Multipurpose vaccine shows new promise in the presence of pre-existing immunity

Graphical abstract. Credit: Cell (2024). DOI: 10.1016/j.cell.2024.07.052 As researchers estimate that nearly all Americans have been exposed to SARS-CoV-2, the virus that causes COVID-19, whether through infection or vaccination, we are no longer “immunologically naive”—in other words, our immune systems are familiar with certain variants of SARS-CoV-2. This familiarity can pose a problem for vaccine development. In immunology, the phenomenon of “original antigenic sin” or OAS is a colloquial term for the body’s first encounter with a virus, which can forever “bias” the immune response to produce antibodies tailored to the initial strain in an exposure, regardless of subsequent infections Read More

New technology ‘lights up’ bacteria in wounds for better infection prevention

Over 6.5 million Americans experience chronic wounds—wounds that do not heal after a few months. Almost all such wounds contain bacteria, which—if not detected and removed—can lead to severe infection and resulting complications, including amputation if a limb is involved. This is especially true for patients with diabetic foot ulcers (open sores), which affects one-third of people with diabetes. Approximately 20% of those who develop a diabetic foot ulcer will require a lower-extremity amputation, according to the American Diabetes Association. When physicians debride (clean out) a wound, they remove as much bacteria as possible. However, they face one key limitation—not Read More

Field of dreams? How some professional cricketers continue to pay the price for sporting excellence

What comes to mind when you think of cricket? Perhaps it’s an idyllic scene of an English village green—people sitting on deckchairs and checkered blankets tucking into a traditional cricket tea while watching mild-mannered players in sparkling whites shouting “howzat?!” every now and then? The stereotype of a genteel, quintessentially English sport can be light years away from the reality, however. In addition to a potentially punishing—and exclusive—working culture, cricket requires a huge amount of endurance, resilience and skill. It’s such a demanding sport, in fact, that test cricket is often referred to as “the ultimate test.” Research from Loughbrough Read More

Also known as latent autoimmune diabetes in adults (LADA), type 1.5 diabetes has features of both type 1 and type 2 diabetes. More people became aware of this condition after Lance Bass, best known for his role in the iconic American pop band NSYNC, recently revealed he has it. So what is type 1.5 diabetes? And how is it diagnosed and treated? There are several types of diabetes Diabetes mellitus is a group of conditions that arise when the levels of Read More

RSV is linked to asthma in children—but we can’t say one causes the other yet

As winter rolls on in Australia, respiratory viruses are everywhere. One of the main culprits is respiratory syncytial virus, or RSV, which has caused more than 145,000 infections around the country so far this year. Most are in children under five. RSV is the leading cause of bronchiolitis and pneumonia (both chest infections) in young children. Each year, at least 1 in 200 children under 5 are hospitalized with RSV in Australia. Babies under 6 months, and especially under 3 months, are at highest risk. RSV infects the airways and lungs, making airway mucus very sticky. Young babies may develop Read More

WHO unveils plan to end African mpox outbreak

As an mpox outbreak continues to rage in Africa, the World Health Organization on Monday launched a six-month plan to quell its spread. “The mpox outbreaks in the Democratic Republic of the Congo and neighboring countries can be controlled, and can be stopped,” WHO Director-General Dr. Tedros Adhanom Ghebreyesus said in a news release announcing the plan. “Doing so requires a comprehensive and coordinated plan of action between international agencies and national and local partners, civil society, researchers and manufacturers, and our Member States,” he added.

FDA clears first automated device to deliver insulin to people with type 2 diabetes

The U.S. Food and Drug Administration on Monday approved the expanded use of an automated insulin pump system to include those with type 2 diabetes. It’s the first such system for use by people with the more prevalent type 2 form of the disease. The FDA first signed off on the system, which automatically adjusts insulin delivery as needed, for type 1 diabetes in 2022. In approving Insulet’s Omnipod 5 insulin delivery system for type 2 diabetes patients, the FDA said the clearance “provides a new option that can automate many of these manual tasks [of tracking and managing blood Read More

Pregnancy after sterilization turns out to be surprisingly common

Pregnancy test. Credit: public domain Tubal sterilization is thought to be a permanent form of birth control and is the most common method of contraception nationally. But a new study led by UC San Francisco reports that tubal surgery fails often enough that some other forms of birth control are usually more effective. The authors found that 3–5% of women in the United States who had their tubes tied later reported an unplanned pregnancy. This failure rate led the authors to suggest that patients who really want to avoid future pregnancy should instead use a contraceptive arm implant or intrauterine Read More

Defining chronic pain for high-performance athletes with disabilities

With the Paris 2024 Paralympic Games just around the corner, the extensive training and the sacrifices athletes make to compete at the games take center stage. For Paralympians and high-performance athletes with spinal cord injuries (SCI), assessing chronic pain plays a key role in their training and readiness to compete. However, the source of chronic pain is often misattributed to acute trauma or overuse injuries. While the International Olympic Committee acknowledges pain management data among Paralympians and athletes with disabilities is limited, few studies have been launched investigating this dilemma. Now, new research from UBC Okanagan highlights the need for Read More

Spain to donate 500,000 mpox vaccines to Africa

Spain will donate 500,000 mpox vaccine doses to countries in central Africa suffering from a surge in cases, the government said Tuesday. The doses amount to 20 percent of Spain’s total mpox vaccine reserves, the health ministry said in a statement without specifying which nations in the region will receive the vaccines or when they will arrive. Spain also urged its European Union peers to follow suit and also donate 20 percent of their mbox vaccine stockpile, saying it” makes no sense to stockpile vaccines where there is no problem,” the statement added. France and Germany have both announced they Read More

DOI: 10.3389/fnbeh.2024.1396811 Crime films, action films, comedies, or documentaries? A person’s favorite film genre reveals a lot about how their brain works. This is the finding of a new study led by the Martin Luther University Halle-Wittenberg (MLU) that compared data on film preferences with recordings of the brain activity of around 260 people. Fans of action films and comedies reacted very strongly to negative emotional stimuli, while participants who favored documentaries or crime films and thrillers had a significantly Read More

Lyme disease early detection could get boost from simpler, faster testing technology

UCLA researchers have developed an AI-enabled technology that could lead to single-tier Lyme disease testing with faster results. Credit: Rajesh Ghosh/UCLA For some unlucky people, time in the great outdoors leads to Lyme disease, an illness causing head, joint and muscle pain, flu-like symptoms, fatigue, and sometimes a rash. Left untreated, those effects can turn debilitating and expand to include paralysis, inflammation of the brain and heart, and problems with memory, hearing and vision that can last for years. Lyme disease, expected to affect more than 600,000 people in the U.S. this year, is caused by a spiral bacterium that Read More

Her acts of kindness initiative is now expanding to more hospitals

Credit: S?n B?m from Pexels Noor Shaik rushed to the bedside of a patient with severe diabetes complications, who had remained upbeat while undergoing surgery to address a foot infection. The woman was now crying uncontrollably, but not due to pain from her operation that morning. What caused her outburst was that her only hair tie had been lost in the operating room. And the wild curls she couldn’t keep out of her face were a breaking point. Shaik, a third-year neurology resident at Penn, ducked out during her break and returned with a $3 pack of hair ties. “Now Read More

Risk for dementia found to be similar with SGLT2 inhibitors, dulaglutide in type 2 diabetes

For older adults with type 2 diabetes, the risk for dementia seems similar with sodium-glucose cotransporter 2 (SGLT2) inhibitors and the glucagon-like peptide 1 receptor agonist (GLP-1 RA) dulaglutide, according to a study published online Aug. 27 in the Annals of Internal Medicine. Bin Hong, from the School of Pharmacy at Sungkyunkwan University in Suwon, South Korea, and colleagues compared the risk for dementia between SGLT2 inhibitors and dulaglutide in a target trial emulation study using nationwide health care data for South Korea obtained between 2010 and 2022. Participants were aged 60 years or older with type 2 diabetes and Read More

Cardiovascular disease disproportionately affects middle-income countries

Cardiovascular disease (CVD) remains the most common cause of death across Europe, but while CVD mortality rates are generally decreasing, the decline is much less in middle-income countries than in high-income countries, according to new data from the European Society of Cardiology (ESC) Atlas of Cardiology, published in the European Heart Journal. The fourth edition of ESC Atlas statistics again demonstrates that CVD is the most common cause of death in the 55 ESC member countries studied. There are over 3 million deaths due to CVD per year—the equivalent of 8,500 deaths per day—which represents 37.4% of all deaths annually. Read More
