The authors propose achievable strategies to increase immunization rates among these groups, including unconventional site distribution and patient reminders.
Recent progress in preventing and treating end-stage renal disease (ESRD) in the US is cause for cautious optimism, with improvements in survival expectations and increased use of fistulas for hemodialysis. However, skyrocketing costs are a major concern, with Medicare costs reaching $20.1 billion in 2004.

A new study by Stanford University atmospheric scientist Mark Z. Jacobson found that ethanol-fueled vehicles increase ozone-related mortalities in the US by about 200 deaths per year compared to gasoline. Nationwide, E85 is likely to increase asthma-related emergency room visits and respiratory-related hospitalizations.
A RAND Corporation study reveals the proportion of severely obese Americans increased by 50% from 2000 to 2005, while moderate obesity grew at twice the rate. This challenges the notion that bariatric surgery can significantly impact morbid obesity trends.
Overweight and obese individuals are at a 50% increased risk of developing asthma, with targeted interventions potentially reducing incidence. Obesity contributes to various respiratory issues, including reduced lung function and increased oxygen cost of breathing.

A USC study found that Healthy Kids coalitions in 28 California counties linked 85,000 kids with health insurance coverage. The success of these coalitions was attributed to diverse stakeholder groups and strong leadership.
A national study estimates that approximately 1 in 4 U.S. females between 14 and 59 years old may have HPV infection, with the highest prevalence among younger women. The study also found a significant trend for increasing HPV prevalence with age, followed by a decline through 59 years.

The research recommends using this cultural concept to encourage open communication and safe-sex practices among couples.
A new study finds that immigration has contributed to declines in interracial marriages in the US, particularly among Hispanic and Asian Americans. Education plays a key role in defining who participates in interracial marriages, with highly educated individuals more likely to cross racial lines to marry. African American intermarriage...
First- or second-generation immigrants make up a disproportionate high percentage of Black student population at U.S. universities, with selectivity increasing proportionally. Despite this, Black immigrant students perform similarly to native counterparts in academic performance.
A new unified score, ABCD², has been developed to predict stroke risk within 2 days of TIA more accurately than existing scores. This improvement can help guide clinical decisions and optimize secondary prevention strategies.
