The fascination with low-carb versus low-fat diet continues; the latest news comes from a study in the Annals of Internal Medicine released today that found that people on both diets lost about the same amount of weight over two years. However, the low-carb group had an edge in raising HDL (good) cholesterol and lowering diastolic blood pressure The study looked at 153 people who were randomly assigned to a low-carb diet, and 154 to a low-fat diet. The low-carb group limited carbohydrate intake to 20 grams per day for the first 12 weeks, then gradually increased fruits, vegetables, whole grains and dairy foods until they reached a desired weight.

Health screenings — they might be tedious, expensive, and time-consuming, but they also can be worth it, even if you're a healthy young adult. Take the case of cholesterol screening. Even though today approximately two-thirds of young adults have one or more risk factors for coronary heart disease, less than 50% of them are screened for high cholesterol, according to a study published in the July-August issue of the Annals of Family Medicine . Coronary heart disease, also known as coronary artery disease, is a buildup of calcium, plaque and fatty material in the arteries that restricts the flow of blood and oxygen to the heart and can lead to a heart attack.

Add sepsis to your list of post-surgery worries. Or, if you're so inclined, to your list of worries in general. First, we'll look at the hospital picture. Researchers at Methodist Hospital, Weill Cornell Medical College, set out to document the incidence, mortality rate and risk factors for sepsis and septic shock after general surgery. And what they found wasn't pretty. Using data from 363,897 patients, they established that sepsis, a life-threatening blood infection, occurred in 2.3% of those patients and that septic shock, dangerously low blood pressure from said blood infection, occurred in 1.6%.

David Axene was flat on his back in a hospital bed with a swollen left leg. His kidneys had shut down. His blood pressure had plunged. Doctors pumped him with potent antibiotics to stave off a deadly infection. Yet there he was sifting through spreadsheets on his laptop, cradling his cellphone to his ear, waving off doctors to finish another conference call. California's top insurance watchdogs had hired Axene to scour Anthem Blue Cross' files for any flaw in the voluminous paperwork that accompanied its rate hikes of up to 39%. Anthem's plan to impose higher premiums March 1 had outraged consumers and politicians alike.

Cancer, diabetes, accidents — heart disease trumps them all, killing more people in the United States than any other condition. The term is actually a fairly broad one, encompassing an array of conditions, but it's most often used as shorthand for coronary artery disease. The latter is caused by a buildup of plaque in the arteries that supply blood to the heart, which in turn can lead to chest pain, arrythmias, heart attacks and heart failure. The risk factors: High blood cholesterol High blood pressure Smoking Diabetes, insulin resistance or metabolic syndrome Being overweight Growing older Family history of heart disease What you can do: Get that high blood pressure and high cholesterol under control.

The differences in men and women's hearts may not be limited to problems of the small and large arteries. Sudden cardiac arrest and how it's predicted may play out differently by gender as well. In the U.S., sudden cardiac arrest claims around 250,000 lives each year, which is about 30% of the total deaths from cardiovascular disease. In sudden cardiac arrest, the heart's electrical activity becomes disrupted or chaotic, preventing the organ from beating. Without immediate treatment by an external defibrillator or cardiopulmonary resuscitation, the victim will die; the mortality rate is 95%. In a heart attack, blood flow to the heart muscle is restricted, causing damage to the muscle.

Men at an above-normal risk of prostate cancer may be able to reduce their risk of developing the disease by taking a drug already on the market. In research reported Wednesday, the drug dutasteride, currently used to shrink enlarged prostates, was found to reduce the risk of prostate cancer by about a quarter in high-risk men. The medication, sold under the brand name Avodart, apparently caused small tumors to stop growing or even to shrink, researchers...

Responding to recent deaths among children who passed through Los Angeles County's child welfare system, Supervisor Mark Ridley-Thomas renewed his call Monday to improve the computer system designed to provide county agencies with information about a child's risk factors for abuse. The Times reported Sunday that an upgraded system for sharing information among agencies about suspicious injuries, domestic violence and other key risk factors was one of a number of unfinished reform efforts.

Pam Levin's daughter weighed less than 5 pounds at birth. But by the time the child turned 3, Levin and her husband had begun to bristle at some of the comments about her. "People would say, ‘She's chunky' or ‘She's a big girl,'" Levin says. The comments may not have been tactful, but the Los Angeles mom caught herself wondering if they were true. Was the adorable, easygoing preschooler overweight? During the child's first year of life, she had been smaller than 95% of children her age, according to pediatric growth charts, weighing about 17 pounds on her first birthday.

Poverty appears to trump smoking, obesity and education as a health burden, potentially causing a loss of 8.2 years of perfect health. In a new study, researchers looked at health and life expectancy data from the National Health Interview Surveys and the Medical Expenditure Panel Surveys and came up with various behavioral and social risk factors that affect quality of life, then used a formula to estimate the quality-adjusted years of life that...
