Research conducted at the University of Illinois shows that children with ADHD demonstrate greater attention after a 20-minute walk in a park compared to similar walks in downtown or residential areas. The study found that even small doses of nature exposure can improve symptoms, suggesting a potential long-term benefit.
A study found that most Medicare patients with stable coronary artery disease who underwent elective angioplasty did not have a recommended stress test performed to confirm the necessity of the procedure. The study suggests that this is due to factors such as patient characteristics, physician volume, and geographic variation in care.
A new report highlights the issue of statistical illiteracy in health, with misleading presentation of relative risks and lack of absolute risk information. The problem affects both doctors and patients, leading to incorrect decisions and actions.
Researchers at Ohio State University have developed an in-vitro method to test the digestion and absorption of arsenic-laden soil. This simulation can help determine the amount of arsenic that dissolves during digestion, allowing for more efficient assessment of contaminated sites.

The test plots out the heartbeat and measures the left ventricle filling pressure, providing a prognostic value in predicting diastolic dysfunction.
A new study found that men and women with a history of concussion recover differently, with females performing worse on reaction time tests and being more symptomatic. The authors recommend an individualized approach to treating concussion patients, taking into account prior history and gender.
A new hearing aid technology has been shown to improve speech intelligibility in noisy environments like restaurants. The open-fit hearing aids with directional microphones outperformed traditional options and provided a 20% improvement in speech clarity.
Researchers Francesco Checchi and Les Roberts argue that an independent body is needed to accurately document death rates during humanitarian emergencies. Such a body could provide a basis for both humanitarian advocacy and political advocacy, and could help prevent the DRC experience from being repeated.
A recent study published in the Journal of Applied Physiology examines the validity of recombinant human erythropoietin (rHuEpo) testing. The research found that the detection power of the test is poor, with high rates of false negative results. This has significant implications for anti-doping efforts and fair competition.

A new study finds that combining symptom screening with a simple blood test can detect over 80% of women with early-stage ovarian cancer and nearly 95% with late-stage disease. This approach may lead to improved cure rates for those diagnosed at an earlier stage.
Researchers found that subtle neurological abnormalities in disability-free older adults can predict cognitive and functional declines. The study used standardized neurological exams to devise a scale measuring these abnormalities, providing evidence for the value of standard neurological exams in predicting future brain health.
Two alternative test methods, the bovine corneal opacity and permeability (BCOP) assay and the isolated chicken eye (ICE) assay, have been accepted for ocular safety testing. These non-animal tests can identify substances that may cause permanent or severe eye damage, reducing animal use in this area.
A new mass spectrometry test can detect naturally occurring steroid levels in athletes more accurately than previous tests. The test is faster to perform and can be run on standard laboratory equipment, making it easier to detect doping violations.
A new study by The Endocrine Society found that male recreational athletes who believed they were using growth hormone experienced improved athletic performance, even when given a placebo. In contrast, female athletes showed little benefit from the placebo effect.
Researchers found that performing a standardized 60-second hair count is a reliable method for assessing hair shedding in healthy men. The study found consistent results across age groups, with an average loss of 10 hairs per minute, and demonstrated low intrapatient variability.
Adults with diabetes are more likely to experience hearing loss due to the disease's impact on nerves and blood vessels in the inner ear. Researchers discovered a strong association between high-frequency sound sensitivity and diabetes, which may be linked to nerve damage and increased risk of heart disease.
A study by researchers at the University of Illinois Chicago found that women experience underreported hot flashes and these symptoms are linked to poor verbal memory. Objective measurement of hot flashes reveals a strong relationship between the number of hot flashes and memory performance.
A new Canadian study found that the standard screening test for high blood sugar in children with risk factors misses nearly 3 times fewer cases of prediabetes than a longer test. The glucose stress test identified more cases of both prediabetes and metabolic syndrome. Early detection is crucial, as it can prevent or delay diabetes.
A new study finds that pregnant women with high insulin resistance are at a higher risk of pregnancy complications, including preeclampsia, premature rupture of membranes, and cesarean sections. Babies born to these women also face increased risks of macrosomia and hypoglycemia.
A Temple University researcher has developed a new method for clinical taste testing using edible strips containing five basic tastes. The strips, created by dissolving polymers in warm water and adding taste stimuli, can measure thresholds for tastants at lower levels than traditional 'sip and spit' tests.
A recent meta-analysis found that smoking is associated with increased risk of poor memory among middle-age adults. Long-term ex-smokers also showed improvement in other health behaviors after quitting smoking.
