What Causes Herpes Cold Sore Flare-Ups? New Study Offers Clues

What Causes Herpes Cold Sore Flare-Ups? New Study Offers CluesWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Scientists may have discovered why cold sores caused by herpes simplex virus (HSV) are triggered by stress, illness and sunburn.The finding could lead to new ways to prevent recurring cold sores and herpes-related eye disease, U.S. and British researchers say. More than half of Americans are infected with herpes simplex virus. It is spread through close contact with someone who has the infection and can re-emerge at any time."Now [that] we understand more what can induce HSV to come out of hiding and reactivate, we can start to understand how this works at the level of the infected nerve cell," said researcher Anna Cliffe, an assistant professor of microbiology, immunology and cancer biology at the University of Virginia in...

Insight Into Why a Prostate Cancer Therapy Works Better for Black MenWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Higher levels of a certain type of immune cell may explain why immunotherapy for prostate cancer is more effective in Black men than in white men, researchers say.The finding could lead to immunotherapy-based precision treatment for localized aggressive and advanced prostate cancer in all races.For the study, the researchers analyzed 1,300 prostate tumor samples and found that, on average, those from Black men had higher levels of plasma cells (a type of immune cell) than those from white men.The researchers also found that higher levels of plasma cells were associated with improved cancer survival following surgery, regardless of the patient's race.The findings suggest that plasma cells could play an important role in prostate cancer...

Too Little Sleep Could Raise Your Dementia Risk

Too Little Sleep Could Raise Your Dementia RiskWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Older adults who get little sleep each night may be at heightened risk of dementia or earlier death, a new study suggests.Researchers found that among 2,600 older Americans, those who were deemed "short sleepers" -- catching no more than five hours of sleep at night -- were more likely to develop dementia or die over the next five years.Their risks were double that of older people who typically got the recommended seven to eight hours of shut-eye.The study, recently published in the journal Aging, is not the first to link poor sleep with dire health outcomes, including dementia.But this study points the finger at a particularly troublesome culprit, according to researcher Rebecca Robbins, of the Division of Sleep and Circadian Rhythms at...

Autopsy Study May Explain Why Some COVID Survivors Have `Brain Fog`WEDNESDAY, Feb. 17, 2021 (HealthDay News) -- One of the least understood effects of COVID-19 infection is "brain fog," a kind of mental confusion that can take hold among seriously ill patients, sometimes lingering long after recovery.Now, a new study has spotted a possible neurological clue in the form of highly unusual cell clusters in the brains of people who had COVID-19."What we're talking about is a situation where patients feel fuzzy and foggy in their thoughts," said study lead author Dr. David Nauen. "It's when you're extremely tired and sluggish, and your mental activity just doesn't seem to be working as crisply and sharply as usual. And it's been reported among COVID-19 patients still under care and afterwards, during the long recovery phase," he explained."We thought it...

Child Bullies at Higher Odds for Substance Abuse as Adults: StudyWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Schoolyard bullies have been making life difficult for kids for eons, often causing lasting damage to their victims. Now, new research shows these bullies can also suffer lasting consequences as they age.Bullies may be more likely to abuse drugs, alcohol and tobacco later in life, and this risk is greater for childhood bullies than those who picked on others during their adolescent years, the study found. Bullying or unwanted aggressive behavior among school-aged kids has become more pervasive in recent years, and the stakes are much higher likely due to social media. In the past, bullying was limited to school, but now bullies can harass their victims online 24/7. About 20% of students aged 12 to 18 have been bullied at school or online in...

Severe COVID-19 Linked With Changes in Eyes of SurvivorsWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Severe eye abnormalities have been found in the eyes of some COVID-19 patients, a new study out of France contends.The findings show the need for eye screening, as well as appropriate treatment and management of potentially serious eye problems in these patients, experts say."We showed that a few patients with severe COVID-19 from the French COVID-19 cohort had one or several nodules of the posterior pole of the [eye's] globe," explained study lead author Dr. Augustin Lecler, a neuroradiologist at the Foundation Adolphe de Rothschild Hospital in Paris.One U.S. ophthalmologist unconnected to the study explained that these nodules appeared in a portion of the eye's globe called the macula."The macula is the area of the retina responsible for...

'Prediabetes' May Be Harming Your Brain, Study Finds

`Prediabetes` May Be Harming Your Brain, Study Finds WEDNESDAY, Feb. 17, 2021 (HealthDay News) -- "Prediabetes" -- where blood sugar levels are high but not yet tipped over into full-blown diabetes -- may pose a threat to brain health, new British research suggests."As an observational study, it cannot prove higher blood sugar levels cause worsening brain health. However, we believe there is a potential connection that needs to be investigated further," said study lead author Victoria Garfield. She's at the Institute of Cardiovascular Science and MRC Unit for Lifelong Health and Aging, at University College London. In their research, Garfield's team analyzed UK Biobank data on a half-million people, average age 58. Compared to those with normal blood sugar ("glucose") levels, people with prediabetes had a 42% higher risk of mental...

Heart Attack More Likely to Kill Instantly in People Who Don`t ExerciseWEDNESDAY, Feb. 17, 2021 (HealthDay News) -- Heart attack patients are less likely to die on the spot if they have been physically active, according to a new study.Researchers analyzed data from more than 28,000 people in Europe who suffered a heart attack in order to see how active or more 'couch potato' lifestyles affected their risk of death.They found that about 18% of patients died within 28 days of their heart attack. Of those, over 62% died instantly.Higher levels of physical activity were associated with a lower risk of death immediately and within 28 days. Compared to inactive patients, those with high levels of leisure-time physical activity had a 45% lower risk of immediate death and a 36% lower risk of death within 28 days. Those who had engaged in moderate levels of...
