Majority of Youth C. Difficile Infections Linked to Doctor Visits
Antibiotics prescribed in a doctor’s office for other conditions are associated with the majority of Clostridium difficile infections, according to a new study in the journal Pediatrics. Researchers from the U.S. Centers for Disease Control and Prevention (CDC) determined that 71 percent of the cases for youth ages 1-17 were linked to the visits, rather than to overnight stays in health care facilities; two-thirds of adult cases are linked to hospital stays. The findings raise the profile of ongoing efforts to reduce unnecessary prescriptions. “Improved antibiotic prescribing is critical to protect the health of our nation’s children,” said CDC Director Tom Frieden, MD, MPH. “When antibiotics are prescribed incorrectly, our children are needlessly put at risk for health problems including C. difficile infection and dangerous antibiotic resistant infections.” Read more on prescription drugs.
Study: Even Slightly Elevated Blood Pressure Can Do Cardiovascular Damage Over Time
Even slightly elevated blood pressure that does not rise to the clinical definition of hypertension can do cardiovascular damage over time, according to a new study in the Journal of the American Medical Association. Researchers at the University of Oklahoma Health Sciences Center analyzed blood pressure data on more than 4,600 participants, all of whom had their readings tracked over 25 years from young adulthood to middle age. They placed the participants in five blood pressure trajectory categories:
- Low-stable: blood pressure that starts low and stays low
- Moderate-stable: blood pressure that begins only slightly elevated and stays that way
- Moderate-increasing: blood pressure begins only slightly elevated and increases over time
- Elevated-stable: blood pressure that starts at elevated levels, but does not increase
- Elevated-increasing: blood pressure that begins elevated and increases over time
The study determined that participants in the moderate-stable group were 44 percent more likely to have coronary artery calcification than those in the low-stable group. Read more on heart health.
Study: Men Die Earlier in More Patriarchal Societies
Gender differences when it comes to mortality rates are higher in more patriarchal societies, meaning women’s rights are good for men’s health, according to a new study in the American Psychological Association’s Evolutionary Behavioral Sciences. Utilized sociodemographic and mortality data from the World Health Organization, researchers from the University of Michigan (UM) School of Public Health found that men living in the top 25 percent most-patriarchal societies were 31 percent more likely to die than men in the least patriarchal quartile, compared to mortality rates for women. Researchers noted that the study only included societies with infrastructures capable of providing reliable data, so the difference could be even more pronounced. Possible explanations include:
- Males in societies where they are more socially dominant tend to engage in riskier behaviors that can lead to death.
- These societies tend to have more resources and social status concentrated in a smaller group of elite men, and men with greater control of resources and social status historically have had more reproductive success.
- In their quest for social dominance, men will go up against other men to gain power and engage in forms of competitive, and sometimes dangerous, behavior.
"Gender inequality is inherently related to inequality in general, and this is bad for both men and women's health, though especially harmful to men in increasing the risk of death," said UM researcher Daniel Kruger. Read more on health disparities.
