Researchers found that individuals with a family history of alcoholism are more likely to prefer sweet tastes than those without. This preference precedes the development of alcoholism and may serve as a marker for genetic risk. The study suggests that a simple test to assess sweet preference could help identify individuals at risk ear...

Despite preferring virtual colonoscopy due to its less invasive nature, patients generally dislike the bowel preparation required for both tests. The study found that most patients reported little pain or difficulty with either procedure, but many expressed discomfort with the advance bowel preparation.
Research finds that lower socioeconomic status groups take longer to recover from stress-induced blood pressure increases, leading to heightened disease risk. The study suggests that adapting quickly to stress is crucial in reducing biological damage.
A single-visit approach combining visual inspection with acetic acid wash (VIA) followed by cryotherapy shows promising results in rural Thailand, with 94% of women testing negative for VIA at one year's follow-up. The program is safe, acceptable, and feasible, achieving moderate population coverage with high satisfaction rates.
ApoB is a more robust indicator of cardiac events than cholesterol levels, according to MUHC cardiologists. Measuring apoB can help identify patients at risk of heart attacks even if their cholesterol levels are well-controlled.
A comprehensive analysis found that Medicare enrollees in higher-spending regions don't have better access to or quality of care, nor do they have better survival rates. In fact, those in higher-spending regions were less likely to receive preventive services.
Researchers found that bystanders correctly administered the Cincinnati Prehospital Stroke Scale (CPSS) directions 96% of the time, detecting key symptoms like arm weakness and slurred speech. This ability can allow untrained adults to act as 'eyes and ears' for emergency dispatchers, potentially improving stroke diagnosis and treatment.
Most prematurely born children show significant improvements in cognitive abilities, such as verbal comprehension and intelligence tests, between ages 3 and 8. Environmental factors like increasing age, maternal education, and absence of brain injury are linked to higher scores.
Researchers discovered that many nonagenarians (people 90-99 years old) are free of Alzheimer's disease or dementia, with some performing in the superior range on cognitive tests. Mild cognitive impairment (MCI) also exists in this age group, but features similar characteristics to those seen in younger individuals.
A new trial found that routine electronic fetal monitoring, known as admission cardiotocography, has no impact on infant death or moderate to severe illness rates. The practice may also increase the risk of unnecessary interventions during childbirth.
A study by the University of Pittsburgh researchers investigated the recovery process in high school athletes with mild concussions. The study found that athletes with longer-lasting on-field symptoms had longer-lasting post-injury symptoms and were more likely to experience significant cognitive declines.
Elderly persons who developed dementia showed similar performance in word pair memory tests without semantic link as those without dementia. However, implicit recall tests improved prediction of dementia risk. Researchers recommend using memory tests that also consider semantic and implicit memory.
A rapid diagnostic test for plague has been developed to detect antigens at low concentrations within 15 minutes of infection. The test is 100% sensitive and reliable, detecting more infections than conventional laboratory assessments and providing opportunities for bioterrorism preparedness and response.
Researchers developed a technique that uses acoustic energy to kill bacteria on medical instruments, reducing the need for heat and chemicals. The method achieved a 90% kill rate using a combination of pressure and isopropyl alcohol, with potential benefits for minimizing infection risk and reducing equipment downtime.
A new test protocol has been shown to accurately diagnose chest pain in emergency patients, with a 100% sensitivity rating for heart attacks. The protocol's accelerated evaluation tool may reduce hospital admissions and improve patient outcomes by enabling earlier diagnosis and treatment.
Researchers link chronic fatigue syndrome to an impaired stress response, finding lower levels of a key hormone in patients. The study suggests that future research should investigate the role of cortisol in the condition.
A large randomized trial found no improvement in cognitive function among postmenopausal women with coronary disease after four years of hormone replacement therapy. The study provides no evidence regarding the effect of estrogen-only therapy on cognition, contradicting some previous studies that showed an improvement in younger women
A study of 51 participants found that serving food on an individual plate with varying portion sizes led to less eating than when participants served themselves. The authors suggest developing strategies to limit portion sizes in restaurants and at home to combat the national obesity epidemic.
