Chronic kidney disease affects over 7.4 million Americans with less than half the kidney function of a healthy adult, while an additional 11.3 million have at least half normal function but persistent protein in their urine. Raising awareness and controlling diabetes and hypertension are critical to reducing progression and complications.
A study found that only 9% of adults with moderately decreased kidney function reported being told they had weakened or failing kidneys, highlighting a need for increased awareness and diagnosis. The researchers suggest that control of diabetes and hypertension are critical in reducing the rate of progression and complications of chron...

The study suggests that early exposure to this protein through breast milk could influence metabolic health later in life.
A recent study by Cincinnati Children's Hospital Medical Center suggests that human milk can significantly reduce the risk of severe infections in extremely low birth weight infants. The research analyzed data from 1270 infants and found that those who received human milk had a lower incidence of sepsis compared to those who did not.

The study also reveals that women's response to targeted therapies is more favorable than men, raising questions about the differences between male and female lung cancer.
A new study found that only 2% of patients who experienced an allergic-like event after the first penicillin prescription had another reaction, despite previous estimates suggesting a 60% rate. The researchers suggest that some patients labeled as penicillin-allergic can safely receive the antibiotic in emergency situations.
The SCD-HeFT trial showed that implantable cardiac defibrillators can reduce total mortality in patients with moderate to severe congestive heart failure. Patients who received an ICD had a three-year mortality rate of 17.1%, compared to 22.3% for those receiving placebo and 24% for those receiving amiodarone.
A study of 9,307 white subjects and 2,902 black subjects found that whites and blacks responded similarly about 90% of the time to common antihypertensive drugs. This challenges traditional racial treatment differences and suggests that physicians should base drug choices on individual patient factors rather than race.
Researchers found that even delayed responses to smallpox cases could still contain the outbreak through targeted vaccination and isolation. Surveillance and containment were more effective than mass vaccination in controlling the spread of smallpox.

The goal is to understand how prostate cancer cells metastasize to bone and discover new genes that may support or inhibit this process.
A study published in JAMA compared screening mammography performance in the US and UK among similar aged women, analyzing 5.5 million mammograms. Despite lower recall rates in the UK, both countries showed similar cancer detection rates, but US women experience more anxiety and false-positive scares.
Researchers found that while black and white Americans have the same amount of early kidney disease, black patients are five times more likely to progress to end-stage renal disease. This disparity may be due to differences in blood pressure control, quality of care, and access to healthcare.

The researchers suggest that adequate vitamin C intake may reduce the risk of peptic ulcers and stomach cancer, although more research is needed to confirm this association.
A new study found that larger exposures to anthrax spores require longer antibiotic therapy. In low-exposure cases, sixty days of antibiotics provide adequate protection, but four months are needed for high-exposure situations.

The researchers measured depressive symptoms using the Patient Health Questionnaire (PHQ) and found that these patients were more likely to report lower healt...
Researchers found that treatment helps reduce depression and feelings of isolation in patients, but it does not change the risk of future heart attacks or death. Half of the study participants received psychological counseling and behavioral therapy, while the other half got standard medical care.
Researchers analyzed data from the World Health Organization and found that countries with quicker control measures had lower fatality rates and slower epidemics. The study suggests that better control measures, such as rapid hospitalization and isolation of cases, are more effective than differences in infectivity or virulence.
A study found that people with a gun in their home are almost twice as likely to die in a gun-related homicide and 16 times more likely to use a gun to commit suicide than those without. Handguns account for most domestic homicides and suicides, highlighting the dangers of gun ownership.
A new meta-analysis of 42 clinical trials involving over 190,000 patients found that low-dose diuretics significantly reduced the risk of heart attacks, strokes, and death. Low-dose diuretics were found to be more effective than other medications in preventing cardiovascular disease morbidity and mortality.
