Current diagnostic criteria for diabetes are based on morning measurements, but patients tested in the afternoon may have higher fasting plasma glucose levels, leading to incorrect diagnoses. The study suggests that applying current criteria to afternoon patients could miss up to half of undiagnosed cases.
Researchers at Cedars-Sinai Medical Center found that 78% of patients with IBS had excessive bacteria in the small intestine. Treatment with antibiotics reduced symptoms in most patients, suggesting a strong association between SIBO and IBS.
A study by UCLA researchers found that androstenedione supplements can contain a contaminant linked to banned steroid nandrolone. The study tested 37 healthy men, revealing that 20 of their urine samples contained enough 19-norandrosterone to test positive for steroid use.
A new non-invasive skin test can measure cholesterol levels in just three minutes, potentially offering a simple way to assess risk of heart disease. The test found that those with the highest skin cholesterol levels also had the greatest number of diseased arteries.

Researchers found that 19 out of 47 people with mild cognitive impairment who had difficulty identifying smells went on to develop Alzheimer's disease. The study suggests that the inability to recognize smells, combined with a lack of awareness about impaired olfactory senses, may be used as a predictor of impending Alzheimer's disease.
Researchers warn that children born with persistent pulmonary hypertension (PPHN) may be at risk for progressive hearing loss, even if standard auditory testing proves normal in the first weeks of life. Periodic hearing tests every six months until age 3 are recommended to avoid delayed diagnosis and its associated costs.
A University of Michigan study suggests that patients with undiagnosed sleep apnea may not always describe their symptoms as 'sleepy', but rather experience fatigue, tiredness, or lack of energy. Laboratory sleep tests revealed interrupted breathing patterns in 73% of the study's subjects.

Research on a monkey vaccine for anthrax suggests that while vaccinated individuals may survive an attack, they could become severely ill, posing a burden on the military. The US Army Medical Research Institute's 1991 test found that monkeys given the vaccine became sick for up to two weeks after inhaling anthrax spores.
A fatal tropical disease has infected large numbers of foxhounds in the US, causing skin lesions, hair loss, and joint issues. At least 12% of dogs have antibodies suggesting exposure to the parasite, with 2% showing a strong response, prompting public health officials to recommend quarantine or euthanasia.

A University at Buffalo study found that men with testicular cancer are two-thirds less likely to have fathered a live infant and nine times more likely to have been diagnosed as infertile than healthy controls. The research contradicts earlier findings that showed no relationship between fertility and testicular cancer diagnosis.
Two studies found that voluntary counseling and testing significantly reduces unprotected intercourse among HIV individuals and couples, with behavior changes maintained over time. The studies also estimate the intervention's cost-effectiveness, finding it averts infections and saves lives at a lower cost than other HIV interventions.

A new study published in the American Journal of Medicine finds that managed care insurance systems can standardize care, eliminate unnecessary tests, and minimize antibiotic resistance by implementing a single guideline for treating uncomplicated urinary tract infections. The study, which included over 3,800 women, showed that using a...
New research suggests that PSA testing alone cannot fully explain the decline in prostate cancer deaths since the early 1990s. Instead, other factors such as changing treatment patterns and misclassification of cause of death may be contributing to the trend.
A study by the University at Buffalo found that a very-low-fat diet can suppress the immune system of trained runners, making them more susceptible to infections. The researchers discovered that high-fat diets, on the other hand, enhanced certain components of the immune system and reduced inflammation.
Smokers who abstain from cigarettes experience increased cravings but show improved reasoning skills upon resuming smoking. The study found that abstinence impairs certain mental tasks, such as letter search, while leaving others unchanged.
Researchers have developed a new technique to spot contaminated corn by listening for telltale noises made by mouldy kernels when exposed to infrared strobe light. The method uses Fourier Transform Infrared Photoacoustic Spectroscopy (FTIR-PAS) and achieves a 96% accuracy in spotting clean and contaminated corn.
Research suggests that children who grow up in smoking households experience small but lasting negative effects on their health, including higher blood pressure and heart rate. The study found that even though the children were not exposed to tobacco smoke at home, they still had higher baseline rates, putting them at risk for hyperten...
Scientists are developing a new urine test that can detect chemical indicators of cancer. The test looks for derivatives of pteridine compounds, which change levels in the urine of cancer patients. This could lead to earlier diagnosis and monitoring of treatment progress.
Researchers have developed virtual reality technology to evaluate mental health problems, including Alzheimer's disease and cognitive impairments. The study found that virtual reality tests showed no significant gender differences in performance.

A new retinal birefringence scanner can measure eye fixation independent of head position, allowing doctors to diagnose amblyopia in young children. The device has the potential to revolutionize communication and daily living for people with disabilities.
A lack of testing on children means doctors must prescribe 'off label', leaving them with uncertainty about the outcome. This also leads to liability for healthcare authorities rather than pharmaceutical companies.
The Rosalind Russell New Arthritis Treatment Program at UCSF is testing innovative therapies targeting specific cells that promote inflammation and joint damage. Current clinical trials focus on rheumatoid arthritis and systemic lupus erythematosus, with promising results expected to lead to nationwide approval.
