Bodybuilders are largely unaware that the protein supplements they use to bulk up might harm their fertility, a new study shows. Four out of five male gym enthusiasts (79%) said they use protein supplements as part of their fitness plan, the poll found. But only 14% had considered how those supplements — which contain high levels of the female hormone estrogen — might impact their fertility, researchers found. “Too much female hormone can cause problems with the amount and quality of sperm that a man can produce,” explained lead researcher Meurig Gallagher, an assistant professor studying infertility at the University of Birmingham in the U.K. Men taking these protein supplements also might be unintentionally dosing themselves with steroids, Gallagher added. “Many protein supplements that can be bought have been found to be contaminated by anabolic steroids, which can cause reduced sperm count, shrunken testicles and erectile dysfunction, amongst other things,” Gallagher said. For this study, Gallagher and his colleagues surveyed 152 avid gym-goers. They found that more than half (52%) of male participants had thought about their fertility prior to being asked. “We found that men are genuinely curious about their fertility when prompted, but that they don’t think about it on their own – likely because societally people still think of fertility as a ‘female issue’ and [incorrectly] believe that men’s fertility doesn’t change…  read on >  read on >

The repeat head injuries suffered by football players, boxers and other athletes appear to affect brain health long after players have given up their sport. New research from Johns Hopkins University in Baltimore could explain why: The persistence in the brain of inflammation tied to the original injury or injuries. “The findings show that participating in repeated collision sports like football may have a direct link to long-term inflammation in the brain,” study senior author Dr. Jennifer Coughlin said in a university news release. She’s an associate professor of psychiatry and behavioral sciences at Hopkins. Key to the new findings is a brain “repair protein,” with the unwieldy name of 18 kDa translocator protein — shortened to TSPO. Whenever a brain sustains injury, TSPO levels quickly rise as the brain tries to heal. TSPO is closely associated with immune cells in the brain called microglia, Coughlin’s group noted. It was thought that spikes in TSPO were only temporary. However, prior studies revealed that levels of the pro-inflammatory protein can remain elevated for up to 17 years. In the new study, the Hopkins team examined PET and MRI brain scans of 27 former NFL players, taken between 2018 and early 2023. They used the scans to compare levels of TSPO in the football players’ brains to those seen in brain scans of 27 former pro college…  read on >  read on >

FRIDAY, DEC. 1, 2023 (Healthday News) — Millions of American kids and teens love to play the game of baseball, but the sport can leave many with elbow pain and injuries, new research finds. “When we look at the forces that baseball players, even Little League baseball players, deal with during routine practice and games, it becomes apparent why elbow injuries are so common amongst this group,” said study co-author Vandan Patel, a radiology-orthopedics research scholar at Children’s Hospital of Philadelphia (CHOP) in Philadelphia. Recent estimates show that 20% to 40% of youth baseball players between the ages of 9 and 12 complain of elbow pain at least once during the season, the researchers noted. “This does not mean that elbow injuries are inevitable in baseball,” Patel noted. “With proper technique and proper rest, these injuries could potentially be avoided.” What sets these youngsters up for injury in the first place? Throwing a baseball repeatedly stresses the growing bones, joints and muscles of the elbows of players. “We conducted this study in order to better understand the patterns of injuries that can occur among youth baseball players with elbow pain,” said senior study author Dr. Jie Nguyen, director for the section of musculoskeletal imaging in CHOP’s Department of Radiology. “A younger player injures differently than an older player. It is our hope that this data…  read on >  read on >

The latest national data show that when it comes to suicide, Americans are increasingly resorting to firearms as their method of choice.  An analysis by researchers at the U.S. Centers for Disease Control and Prevention finds that of the nearly 50,000 suicides recorded in the United States in 2022, more than half (27,000) involved a gun.   Gun-related suicides have been on the rise over the past two decades, but they jumped by 11% during the pandemic, reported a team led by Wojciech Kaczkowski, of the CDC’s National Center for Injury Prevention and Control.  “The persistent upward trend in firearm suicide rates since 2020 across all racial and ethnic groups, coupled with unprecedented high rates during 2022, highlight the need for continuing prevention efforts,” the researchers said in their report. In sheer numbers, white Americans suffered the highest death toll from gun suicide, the report found. But the rate at which guns are being used in suicides is rising fastest among minorities, Kaczkowski’s group noted. For example, while the rate of suicides by firearm rose by 9% among white Americans between 2019 and 2022, it rose by 28% among Hispanic Americans, 42% among Black Americans and 66% among American Indians/Alaska Natives, the study found. Why the sharp rise? Unemployment pressures during the pandemic and lack of access to mental health care may have played a…  read on >  read on >

Teens glued to Instagram, TikTok and other social media are more likely to drink, take drugs, smoke and engage in risky sexual behaviors, a new review warns. For example, spending at least two hours a day on social media doubled the odds of alcohol consumption, compared with less than two hours daily use, researchers report in the Nov. 29 issue of BMJ. The results show that teens are particularly susceptible to social media depictions of risky health behaviors like alcohol use or unhealthy eating, the investigators said. “Experimental and risk-taking behaviors are an inherent part of adolescence,” the team concluded in a journal news release. “However, as safeguards for a digital world are still evolving, precaution across academic, governmental, health and educational sectors may be warranted before the risks of adolescents’ use of social media is fully understood.” For the review, researchers analyzed more than 250 social media measures reported in 73 studies conducted between 1997 and 2022, involving 1.4 million kids ages 10 to 19. The pooled data showed that frequent or daily social media use is associated with a 48% increased risk of alcohol consumption, a 28% increased risk of drug use and an 85% increased risk of smoking, compared to infrequent surfing of social media. Social media seems to have an influence over teens’ sexual choices as well. Frequent or daily social…  read on >  read on >

Women in a Chinese study who sat for more than six hours each day faced substantially higher odds of developing uterine fibroids before menopause, a new study has found. Overall, more sedentary women had double the risk of developing the often painful and harmful uterine growths prior to menopause, say a team led by Dr. Qiong Meng , of Kunming Medical University in Kunming, China. Why the link? Obesity linked to a ‘couch potato’ lifestyle could be one factor, since “studies have shown that obesity is a risk factor for uterine fibroids,” Meng’s group noted. Sedentary lifestyles and obesity are also tied to rising levels of circulating estrogen, as well as other hormones known to contribute to fibroids, the team added. Finally, being sedentary can also help lead to deficiencies in vitamin D — yet another risk factor for these growths. The findings were published Nov. 29 in the journal BMJ Open. According to the study team, uterine fibroids are benign tumors that are exceedingly common among women. They sometimes cause no symptoms, but in many cases can trigger “abnormal bleeding, pain in the pelvic and abdominal organs, adverse reproductive outcomes of infertility,” the researchers noted. Sometimes fibroids become so severe that a hysterectomy is advised. In the new study, Meng’s team analyzed data on over 6,600 women from across China who were between the…  read on >  read on >

THURSDAY, Nov. 30, 2023 (Healthday News) — The U.S. Environmental Protection Agency announced Thursday that it plans to require the removal of all lead pipes from the country’s water systems. The proposed rule, an ambitious effort that will cost up to $30 billion over the next decade, would affect about 9 million pipes that send water to homes in countless communities across the United States. “Lead in drinking water is a generational public health issue, and EPA’s proposal will accelerate progress towards President Biden’s goal of replacing every lead pipe across America once and for all,” EPA Administrator Michael Regan said in an agency news release. “With collaboration and the focused actions proposed today, EPA is delivering on our charge to protect all Americans, especially communities of color, that are disproportionately harmed by lead in drinking water systems.” Utility companies will be expected to cover most of the cost of pipe replacements, but there is $15 billion available in the 2021 infrastructure law to help them pay for it, the agency noted. The proposal “is grounded in the best available science and successful practices utilized by drinking water systems to protect children and adults from lead in drinking water,” added EPA Assistant Administrator for Water Radhika Fox. “Cities like Newark, N.J., Benton Harbor, Mich., and Green Bay, Wisc. have all successfully gotten the lead out of their water…  read on >  read on >

Elevated levels of thyroid hormone appear to harm the aging brain, increasing seniors’ risk of dementia or other cognitive disorders, a new study finds. High levels of thyroid hormone — a condition called thyrotoxicosis — was associated with thinking problems whether they came from an overactive thyroid gland or from taking thyroid medication, researchers found. “Our results suggest that an increased risk of cognitive disorders is among the potential negative consequences of thyroid hormone excess, a common consequence of thyroid hormone therapy,” said senior researcher Dr. Jennifer Mammen, an assistant professor of medicine at Johns Hopkins University School of Medicine in Baltimore. “Clinicians considering thyroid hormone therapy in older adults should avoid over-treatment by using age-appropriate treatment strategies,” Mammen added in a university news release. Some prior studies have suggested that high thyroid levels were associated with an increased risk of cognitive disorder, but those results have been mixed, researchers said. Additionally, those earlier studies didn’t include excess thyroid hormone caused by taking medication. Thyroid hormone is among the most common prescriptions in the United States, researchers said. As many as 20% of people prescribed thyroid hormone might be taking too much, putting them at risk for thyrotoxicosis. “Our goal was to investigate whether aggressive treatment practices … can also possibly cause cognitive harm,” said lead researcher Roy Adams, an assistant professor of psychiatry and…  read on >  read on >

Minding your heart health when you’re young could spare your brain from dementia decades later, new research confirms. Chinese researchers looked at data on more than 450,000 older Britons. They found that people who’d already been in poor cardiovascular health before they reached the age of 45 had a 25% higher odds of developing dementia, compared to those with better heart heath. “What surprised us most was the linear relationship between age of coronary heart disease onset and dementia,” said senior study author Fanfan Zheng. “This shows the huge detrimental influence of premature coronary heart disease on brain health,” added Zheng, a researcher at the Chinese Academy of Medical Sciences & Peking Union Medical College in Beijing. The findings were published Nov. 29 in the Journal of the American Heart Association. Doctors have long known that failing heart health can pose a threat to the brain, with links to poorer brain circulation and even strokes. But does the timing of heart disease onset matter? To find out, Zheng’s group analyzed data from the UK Biobank database. They looked at the medical records of hundreds of thousands of Britons who averaged 57 years of age when they were enrolled in the Biobank. About 12% of the participants had already been diagnosed with heart disease by the time they enrolled. The researchers then tracked cases of new-onset…  read on >  read on >

Migraine sufferers would do better to talk to their doctor about a prescription drug than reaching for a bottle of ibuprofen, a new study finds. Drugs like triptans, ergots and anti-emetics can be two to five times more effective for treating migraines than ibuprofen, according to a report published Nov. 30 in the journal Neurology. “These results confirm that triptans should be considered earlier for treating migraine, rather than reserving their use for severe attacks,” said researcher Dr. Chia-Chun Chiang, a neurologist with the Mayo Clinic in Rochester, Minn. People in the throes of a migraine experience intense throbbing head pain, sensitivity to light and sound, nausea or vomiting, and even thinking issues. There are many treatments available, but not much head-to-head data comparing their effectiveness, Chiang said. For this study, Chiang and her colleagues tracked more than 3 million migraines self-reported by nearly 300,000 people using a smartphone app. The app allows users to monitor the frequency of their migraines, the triggers that caused them, the symptoms they had and the effectiveness of the medication they took. Participants reported trying different medications for their migraines a total of 4.7 million times, and noted whether each helped or not.  Researchers used that information to calculate the relative effectiveness of each drug, evaluating a total 25 meds across seven drug classes. The top three classes of…  read on >  read on >
