Implementing pay-for-performance incentives can significantly reduce these costs by encouraging improved disease management and adherence to clinical guidelines.
A study comparing reflux esophagitis in African-Americans and non-Hispanic whites found similar frequencies of complications, except for Barrett's esophagus. Non-Hispanic whites had higher rates of endoscopic and histological Barrett's esophagus and heartburn-induced endoscopy.
A recent study found that US counties with a higher percentage of African-American patients tend to have fewer gastroenterologists and radiation oncologists, while those with more Asian Americans have more specialists. This disparity is linked to disparities in access to quality healthcare services.
A study published in Journal of the American College of Surgeons reveals that segregation is associated with decreased access to surgical services and increased emergency room visits among minority populations. The research highlights the need to address racial disparities in healthcare, particularly in the most segregated areas.
A study on guppies led by UC Riverside's Swanne Gordon found that the fish adapted to a new environment in less than 30 generations, or eight years. The guppies developed larger and fewer offspring with each reproductive cycle in the low-predation environment, but not in the high-predation environment.
Research on Hispanic children in the US reveals a high prevalence of obesity, largely attributed to suboptimal diets and sedentary lifestyles. The VIVA LA FAMILIA Study found that even non-overweight participants had inadequate diets, with low levels of essential nutrients and excessive sugar consumption.
A new study found that retail clinics are more likely to be located in higher-income areas, making it difficult for poor and underserved communities to access medical care. The clinics' location may be an adjunct to existing traditional medical care rather than addressing unmet needs.
A study published in Archives of Internal Medicine found that retail clinics tend to be located in areas with higher median incomes and home ownership rates. In contrast, counties without these clinics have higher uninsured rates and lower socioeconomic status.
A study found that Asian Americans who adopted more aspects of Western culture were more likely to engage in sun exposure behaviors, such as deliberate sunbathing and getting more sun on weekends. This association may lead to increased risk of skin cancer among this population.
Researchers at the University of Cincinnati analyzed lung, colon, breast, prostate, bladder, kidney and skin cancer data in transplant recipients compared to the general population, finding worse disease-specific survival rates for each type of cancer. Immunosuppressive therapies may play a role in the poorer outcomes.
Researchers found nearly one in 12 people reported increased alcohol consumption, with similar rates for drugs and cigarettes. The study suggests a potential behavioral health effect of man-made disasters like terrorism on substance misuse.

A DNA study confirms that Native Americans and Greenlanders share a common ancestral population, with the '9-repeat allele' present in all Native American populations and absent in other Asian groups. This evidence supports the single ancestral population theory, ruling out multiple mutations and natural selection hypotheses.
A study found that a lean population would consume 20% less food and produce fewer greenhouse gases than an obese one. Staying slim also leads to lower transport-related emissions.

The study suggests that increased awareness and diagnosis of celiac disease can lead to health care costs savings.
Researchers found that many Hispanics were misclassified in a 'some other race' category, leading to incorrect projections of racial diversity. The study suggests that Americans may struggle to accurately report their ancestry due to generational memory loss and stigma around interracial relationships.
A study published in the Journal of the American College of Surgeons reveals a critical shortage of surgeons in Maryland, with rural areas particularly affected. The shortage is expected to worsen over the next decade due to an aging physician population and limited medical education programs.
A recent study by SAGE found that Mexican immigrants face harsher treatment in California than Texas, with more anti-immigrant policies and lower wages. The longer they stay in the US, the fewer disadvantages they face.

A study found that about 64% of US hospitals did not give tissue plasminogen activator (tPA) to Medicare patients between 2005 and 2007. The researchers also discovered that 40% of the US population resides in a county without a hospital that provides tPA treatment.
A recent study by Henry Ford Health found that Arab-American women in southeast Detroit have dangerously low vitamin D levels, averaging 8.5 ng/mL, with those who wore the hijab showing even lower levels of 4 ng/mL. The researchers recommend supplementing with a vitamin D supplement to address this deficiency.
A new mathematical model predicts that pre-exposure prophylaxis (PrEP) could substantially reduce the lifetime risk of HIV infection, but its cost-effectiveness varies depending on target population and drug costs. With modest improvements, PrEP might be as effective as other public health interventions.

According to University of Miami professor Ira M. Sheskin, the strength of the Jewish-American vote is not measured by its numbers but by its geographic concentrations. The Jewish population has shifted from Northeast and Midwest to South and West, maintaining a significant influence on US politics.

A new study analyzing ancient DNA from 160 mammoth samples across Holarctica suggests that North American mammoths replaced dwindling Siberian populations around 50,000 to 5,000 years ago. The findings refute the notion of climate change as a direct cause of extinction, instead pointing to a complex pattern of migration and evolution.
A study found that Americans with health insurance are equally likely to access eye care as Canadians, while those without insurance visit less often. Individuals with higher incomes and optional vision insurance tend to use eye care services more frequently.

Researchers from Helmholtz Centre for Environmental Research propose five-step action plan to regulate cormorant populations in Europe. A common management strategy is needed due to varying national attitudes towards culling, with some countries opposing the practice.
Researchers have developed a new computational method to reconstruct viral populations with improved accuracy and efficiency. This method, based on pyrosequencing, reduces error rates and yields faster results at a lower cost.
A long-term study found that 4% of male and 19% of female US population experienced stagnating or declining health conditions between the 1980s and 2001. The main causes were related to smoking, high blood pressure, and obesity.
A new study found that between 1983 and 1999, death rates in women increased in low-income counties due to chronic diseases like smoking, high blood pressure, and obesity. Inequality in life expectancy worsened across US counties, particularly for disadvantaged populations.
The number of general surgeons per 100,000 Americans has declined by over 25% since 1981, mainly due to an aging population and a lack of rural training opportunities. Rural areas are disproportionately affected, with urban areas experiencing a slightly greater decline.
