Marked each October 15, the day promotes HIV testing among Hispanics/Latinos, who made up about 15% of the US population in 2008 but 19% of people diagnosed with HIV in reporting areas. Barriers cited include poverty, migration, stigma and acculturation.

World Arthritis Day
A CDC study counts almost 50 million US adults living with arthritis in 2007-2009, up from 46 million in 2003-2005, with over 21 million reporting activity limits. One in three obese adults has arthritis, and losing about 11 lbs can cut knee osteoarthritis risk by half.

Pink News: Reproductive factors linked to breast cancer
An Iranian case-control study of 100 patients and 200 controls found later first pregnancy and abortion accompanying 310 and 193 percent higher breast cancer risk, while five or more births went with 91 percent lower risk. A Sri Lankan study tied longer breastfeeding to lower risk.

Neonatal Jaundice Linked to Autism, Is Vitamin D the Missing Link?
A Danish study of 733,826 children published in Pediatrics found newborns with jaundice were 87 percent more likely to be diagnosed with a psychological disorder and, among those born at term, 56 percent more likely to have autism. Babies born October through March were 97 percent more likely.

ADHD is a genetic disorder - study suggests
A Lancet study found children with ADHD were more likely to carry small duplicated or missing DNA segments, some overlapping variants tied to autism and schizophrenia. The article stresses the study does not prove these copy number variants cause the disorder.

Why is the United States the Fattest of 33 Nations?
An OECD report ranks the United States first in obesity among 33 countries, with 70 percent of Americans now at unhealthy weights against half in 1980. The piece points to screen-based sedentary time, the decline of the family dinner and easy access to high-calorie food.

Pertussis (Whooping Cough) – What You Need To Know
A CDC piece on whooping cough, a very contagious bacterial disease that hits hardest in infants too young to be fully vaccinated. Protection from the childhood shots fades, so adolescents and adults need Tdap boosters. Several states, including California, reported outbreaks.

HIV among Gay, Bisexual and Other Men Who Have Sex with Men (MSM)
A CDC fact sheet reports that gay and bisexual men make up about 2 percent of the US population yet accounted for 53 percent of new HIV infections in 2006 — the only risk group whose infections have climbed steadily since the early 1990s. Young black MSM saw the most new infections.
Disease
CDC: Gay, bisexual men account for more than 50% of HIV cases
A CDC letter for National Gay Men's HIV/AIDS Awareness Day reports that gay and bisexual men and MSM who inject drugs account for 57% of new US HIV infections. A survey of 8,153 MSM in 21 cities found 19% infected, and 44% of those were unaware of it.

Gay men at increased risk of HIV - CDC
CDC's National HIV Behavioral Surveillance found 19 percent HIV prevalence among 8,153 men who have sex with men interviewed in 21 cities in 2008, highest among non-Hispanic blacks at 28 percent. Of those infected, 44 percent did not know it, rising to 63 percent among men aged 18 to 29.

Is Female Sexual Dysfunction the Next Big Disease
In an interview, Sex, Lies, and Pharmaceuticals co-author Ray Moynihan argues drug companies now help build the science behind 'female sexual dysfunction' and 'hypoactive sexual desire disorder' in order to create a market for a 'pink' Viagra.

Worldwide dementia care costs $601 billion in 2010 - report
Alzheimer's Disease International puts 2010 care costs for 35.6 million people with dementia at $601 billion, more than 1 percent of global GDP. The report expects cases to double by 2030 and more than triple by 2050, with costs rising fastest in the developing world.

H1N1 Swine Flu Even Milder than Seasonal Strains
A JAMA study comparing pandemic H1N1 with seasonal H1N1 and H3N2 found similar symptoms and complication risks and no substantial rise in hospitalization or pneumonia, though the pandemic strain fell disproportionately on children and young adults.
Disease
Kids and Diabetes Risk: Do Chromosomes Hold New Clues?
USDA-funded researchers led by Nancy Butte are fine-mapping a region of chromosome 13 that influences fasting blood sugar, identified from DNA and glucose tests on 1,030 Hispanic children aged 4 to 19, hoping to yield biomarkers for type 2 diabetes risk.
Disease
Prostate Cancer
A CDC overview of prostate cancer: symptoms range from trouble urinating to pelvic pain, or none at all; risk rises with age, African-American ancestry and family history. In 2006, 203,415 men were diagnosed and 28,372 died. Experts still disagree on whether screening saves lives.
Disease
More genetic variants affect breast cancer risk
A Mayo Clinic-led study identified five single nucleotide polymorphisms on chromosome 19p13 that modify breast cancer risk in BRCA1 mutation carriers. The same variants were tied to estrogen-receptor-negative and triple-negative breast cancer in women without BRCA1 mutations.
