Chronic kidney disease (CKD), which afflicts more than 26 million Americans, is a condition in which individuals experience a slow loss of kidney function over time.

Low rate of patient monitoring found following initiation of therapy for heart failure
Although frequent laboratory monitoring of patients with heart failure following initiation of mineralocorticoid receptor antagonists is supported by the results of large clinical trials and recommended in guidelines, there appears to be low rates of monitoring in clinical practice, according to a study in the Nov.

People who mostly eat meals prepared at home may have a slightly lower risk of developing type 2 diabetes.

Moving to a walking neighborhood is good for your blood pressure
People who moved from a neighborhood that required a vehicle to run errands to one that made walking-errands convenient were significantly less likely to have high blood pressure than people who moved from one low-walkability neighborhood to another low-walkability neighborhood Specifically, people who moved to a highly walkable neighborhood had a 54 percent lower risk of high blood pressure than those who moved to a more car-dependent neighborhood over 10 years of follow up.

When UA researcher Nicholas Strausfeld co-authored a 2012 paper in Nature describing an ancient, fossilized brain, it challenged the long-held notion that brains don't fossilize.

Poor air quality increases patients' risk of heart attack, new study finds
People with heart disease face an increased risk of a serious heart attack during poor air quality days, according to a major new study presented today at the American Heart Association Scientific Session in Orlando.

Revascularization before exercise program improves walking for patients with PAD
Among patients with peripheral artery disease and intermittent claudication (cramping pain in the legs due to poor circulation in the arteries, aggravated by walking), a combination therapy of endovascular revascularization (an invasive procedure to improve blood flow in an artery) followed by supervised exercise resulted in greater improvement in walking distances and health-related quality-of-life measures at one year compared with supervised exercise only, according to a study in the Nov.

Shared financial incentives for physicians and patients improve LDL cholesterol levels
In a study examining the effect of financial incentives to improve lipid levels among patients in primary care practices, shared financial incentives for physicians and patients, but not incentives to physicians or patients alone, resulted in a modest reduction of low-density lipoprotein cholesterol levels after 12 months, according to a study in the Nov.

Taking public transportation instead of driving linked with better health
Commuting by public transportation is linked to a lower risk of having high blood pressure, diabetes, and overweight than commuting by car or bike.

Exploring the paradox of metabolically healthy obesity
Australian researchers have defined some key characteristics of the metabolically healthy obese -- those obese individuals who remain free from type 2 diabetes and other disorders. that usually associate with obesity.

High job demands, stress and job insecurity are among the main reasons why people go to work when they are ill, according to new research by an academic at the University of East Anglia.

Poverty influences effects of race and education on pain after knee replacement surgery
Findings from a study by researchers from Hospital for Special Surgery suggest that lower socioeconomic status at the community level significantly increases the risk of pain and poor function following a knee replacement.

Video-based CPR training may be as valuable as hands-on approach, Penn study finds
Using a video to train family members of patients at risk for cardiac arrest in CPR may be just as effective as using the traditional hands-on method with a manikin, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Effectiveness of drug to improve natriuretic peptide levels for chronic heart failure
Mihai Gheorghiade, M.D., of the Northwestern University Feinberg School of Medicine, Chicago, and colleagues randomly assigned 456 patients with worsening chronic HF and reduced left ventricular ejection fraction (a measure of how well the left ventricle of the heart pumps with each beat) to receive placebo or 1 of 4 daily target doses of the medication vericiguat for 12 weeks.

The No. 1 killer is invisible to most women
Even though heart disease and stroke are the No. 1 killer of US women, few women say they feel a personal connection to cardiovascular disease, according to a nationally representative survey.

Diagnosing & treating diabetes in heart attack patients improves heart outcomes, study finds
People with heart problems often have diabetes, which puts them at greater risk for heart attacks, heart failure and stroke.
