Practice makes perfect? Not so much

Tweet

EAST LANSING, Mich. — Turns out, that old "practice makes perfect" adage may be overblown.

New research led by Michigan State University's Zach Hambrick finds that a copious amount of practice is not enough to explain why people differ in level of skill in two widely studied activities, chess and music.

In other words, it takes more than hard work to become an expert. Hambrick, writing in the research journal Intelligence, said natural talent and other factors likely play a role in mastering a complicated activity.

Antibiotic therapy appears beneficial for patients with COPD

Tweet

ATS 2013, PHILADELPHIA ─ Extended use of a common antibiotic may prolong the time between hospitalizations for patients suffering from chronic obstructive pulmonary disease (COPD), according to a post-hoc analysis of a multicenter study which compared the hospitalization rates of patients treated with a 12-month course of azithromycin to the rates of those treated with placebo.

The results of the current analysis will be presented at the ATS 2013 International Conference.

Exercise levels may predict hospitalizations in COPD population

Tweet

ATS 2013, PHILADELPHIA ─ Clinical measurement of physical activity appears to be an independent predictor of whether or not patients with chronic obstructive pulmonary disease (COPD) will end up being hospitalized, according to a new study conducted by researchers in Connecticut. The study also corroborates an earlier investigation that linked higher levels of inactivity with an increased incidence of hospitalizations among patients with COPD.

The results of the study will be presented at the ATS 2013 International Conference.

Hospitals' cardiac arrest incidence and survival rates go hand in hand

Tweet

ANN ARBOR, Mich. — Hospitals with the highest rates of cardiac arrests tend to have the poorest survival rates for those cases, new University of Michigan Health System research shows.

Meanwhile, hospitals that do the best job of preventing cardiac arrest among their patients tend to be better at saving patients with cardiac arrest, according to the findings that appear in JAMA Internal Medicine.

Bronchodilators appear associated with increased risk of cardiovascular events

Tweet

A study of older patients with chronic obstructive pulmonary disease (COPD) suggests that new use of the long-acting bronchodilators β-agonists and anticholinergics was associated with similar increased risks of cardiovascular events, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

Association between in-hospital cardiac arrest survival rates, prevention of cardiac arrests

Tweet

Hospitals with higher rates of survival among patients who experience in-hospital cardiac arrest also appear to have a lower incidence of in-hospital cardiac arrest, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

Lena M. Chen, M.D., M.S., of the University of Michigan, Ann Arbor, and colleagues identified 102,153 cases of in-hospital cardiac arrest at 358 hospitals between January 2000 and November 2009.
