Study examines characteristics, risk factors among HIV-positive persons born outside the US

Compares results to persons with HIV born in the US

2012-07-23
(Press-News.org) WASHINGTON, D.C. – An examination of the characteristics of persons born outside the United States diagnosed with HIV while living in the U.S. finds that, compared to U.S.-born persons with HIV, they are more likely to be Hispanic or Asian, and to have a higher percentage of HIV infections attributed to heterosexual contact, according to a study appearing in JAMA being published online.

H. Irene Hall, Ph.D., of the Centers for Disease Control and Prevention, Atlanta, presented the findings of the study at a JAMA media briefing at the International AIDS Conference.

"Persons born outside the United States comprise approximately 13 percent of the total U.S. population and represent a varied group of people, including students, skilled workers, family members of U.S. citizens, undocumented migrants, naturalized citizens, and refugees," according to background information in the article. "Although more than 95 percent of persons with HIV in the world live outside the United States, an understanding of HIV infection in persons born outside but living in the United States allows for both a new perspective on HIV in this country as well as a better understanding of the health status and health education needs of persons born outside the United States." The authors add that it can be difficult for persons born outside the United States to learn about HIV prevention, access HIV testing, and obtain timely medical care because of language and cultural barriers.

Dr. Hall and colleagues examined the demographic, geographic, and risk factor characteristics of U.S.-born and persons born outside the U.S. who received a diagnosis of HIV while living in the U.S. from 2007 through 2010 in 46 states and 5 U.S. territories, as reported to the National HIV Surveillance System. The category of persons were defined as persons born outside the United States and its territories was inclusive of naturalized citizens.

The researchers found that from 2007 through 2010, a total of 191,697 persons received a diagnosis of HIV. Of these, 30,995 (16.2 percent) were born outside the United States. The 4 states (California, Florida, New York, and Texas) reporting the highest numbers of persons born outside the U.S. and diagnosed with HIV were also the top 4 states with HIV cases overall. The majority of HIV cases occurred in males (n = 124,863 [77.7 percent] among U.S.-born males vs. n = 22,773 [73.5 percent] among males born outside the United States).

Regarding race/ethnicity, the researchers found that the proportion of persons born outside the United States varied by category. "Of the 55,574 HIV diagnoses in whites, 1,841 (3.3 percent) were in persons born outside the U.S.; of 86,547 diagnoses in blacks, 8,614 (10.0 percent) were in persons born outside the U.S. Of the 42,431 HIV diagnoses in Hispanics, 17,913 (42.2 percent) were in persons born outside the U.S. Of 3,088 HIV diagnoses in Asians, 1,987 (64.3 percent) were in persons born outside the U.S."

Overall, 39.4 percent of HIV diagnoses in persons born outside the United States (men and women combined) were attributed to heterosexual contact; for U.S.-born persons, 27.2 percent was due to heterosexual contact. For both males born outside the U.S. and U.S.-born men, the majority of HIV diagnoses were in men who have male-to-male sexual contact.

Of the 25,255 persons diagnosed with HIV with a specified country or region of birth outside the United States, the most common region of birth origin was Central America (including Mexico; n = 10,343 [41.0 percent]), followed by the Caribbean (n = 5,418; 21.5 percent), Africa (n = 3,656; 14.5 percent), Asia (n = 1,995; 7.9 percent), and South America (n = 1,929; 7.6 percent).

The researchers note that the date of first entry into the United States is not collected on the HIV case report form, so it is not possible to know whether HIV infection preceded or followed immigration.

"These findings demonstrate the diversity of the HIV-infected population born outside the United States, presenting many clinical and public health challenges," the authors conclude.

Editorial: HIV Infection Among Persons Born Outside the United States

Mitchell H. Katz, M.D., of the Los Angeles County Department of Health Services, and Deputy Editor, Archives of Internal Medicine, writes in an accompanying editorial that the findings of this study "suggests that persons born outside the United States who reside in the United States are a heterogeneous group."

"This study and other studies suggest that these persons are in need of appropriate education and outreach, testing and treatment, and mental health services including specialized services for those who experience traumatic events in their home countries or during the immigration process, substance treatment for those addicted to drugs, as well as HIV care for those who are infected. Although these lessons may apply regardless of country of origin for HIV-infected persons, the effectiveness of these messages and interventions will require culturally relevant delivery to each specific population of immigrants."

Artificial jellyfish swims in a heartbeat

2012-07-23
Cambridge, Mass. — July 22, 2012 — Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish." The finding serves as a proof of concept for reverse engineering a variety of muscular organs and simple life forms. It also suggests a broader definition of what counts as synthetic life in an emerging field that has primarily focused on replicating life's ...

New method for associating genetic variation with crop traits

2012-07-23
A new technique will allow plant breeders to introduce valuable crop traits even without access to the full genome sequence of that crop. The technique, published in the journal Nature Biotechnology, links important agronomic traits in crop plants with active regions of the genome. Instead of requiring knowledge of the crop's complete genome, it identifies only expressed genes. "For many crop plants, markers are still lacking because of the complexity of some plants' genomes and the very high costs involved," said Professor Ian Bancroft, who led the study at the John ...

WASHINGTON, D.C. – Included in the 2012 International Antiviral Society-USA panel recommendations for human immunodeficiency virus (HIV) patient care is that all adult patients, regardless of CD4 cell count, should be offered antiretroviral therapy (ART), according to an article in the July 25 issue of JAMA, a theme issue on HIV/AIDS. Other new recommendations include changes in therapeutic options and modifications in the timing and choice of ART for patients with an opportunistic illness such as tuberculosis. Melanie A. Thompson, M.D., of the AIDS Research Consortium ...

Medusa reimagined: Caltech-led team reverse engineers a jellyfish with the ability to swim

2012-07-23
PASADENA, Calif.—When one observes a colorful jellyfish pulsating through the ocean, Greek mythology probably doesn't immediately come to mind. But the animal once was known as the medusa, after the snake-haired mythological creature its tentacles resemble. The mythological Medusa's gaze turned people into stone, and now, thanks to recent advances in bio-inspired engineering, a team led by researchers at the California Institute of Technology (Caltech) and Harvard University have flipped that fable on its head: turning a solid element—silicon—and muscle cells into a freely ...

New genomic sequencing method enables 'smarter' anaysis of individual cells

2012-07-23
July 22, 2012, New York, NY and Stockholm, Sweden – Only by viewing a Seurat painting at close range can you appreciate the hidden complexities of pointillism – small, distinct dots of pure color applied in patterns to form an image from a distance. Similarly, biologists and geneticists have long sought to analyze profiles of genes at the single cell level but technology limitations have only allowed a view from afar until now. Research published in the July 22 issue of Nature Biotechnology, shows for the first time that a novel genomic sequencing method called Smart-Seq ...

Pre-season fitness makes no difference to risk of injury

2012-07-23
But the type of sport played and gender did, according to a new study published in BioMed Central's open access journal Sports Medicine, Arthroscopy, Rehabilitation, Therapy & Technology. This study into varsity athletics found that women had a shorter time to injury than men and that certain sports, such as volleyball, also had a significantly shorter time to injury than others, such as hockey or basketball. Fitness evaluation and pre-participation are standard practice in university sport. They screen the athletes for health problems and for high-risk behaviors which ...

Genetic mutations that cause common childhood brain tumors identified

2012-07-23
STANFORD, Calif. — Researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital have identified several gene mutations responsible for the most common childhood brain tumor, called medulloblastoma, adding evidence to the theory that the diagnosis is a group of genetically distinct cancers with different prognoses. These and accompanying findings are likely to lead to less-toxic, better-targeted treatment approaches over the next two years, the researchers said. "We tend to treat all medulloblastomas as one disease without taking into ...

Key mutations discovered for most common childhood brain cancer

2012-07-23
Boston, Mass., July 22, 2012– Researchers at Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) and several collaborating institutions have linked mutations in specific genes to each of the four recognized subtypes of medulloblastoma, the most common malignant brain tumor of children. The discovery, reported July in the journal Nature, provides doctors with potential biomarkers for guiding and individualizing treatment and reveals prospective therapeutic opportunities for countering this devastating malignancy. The study was conducted by a research team led by Scott ...

New clues to the early Solar System from ancient meteorites

2012-07-23
Washington, D.C. — In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from a team including Carnegie's Doug Rumble and Liping Qin focuses on one particularly old type of meteorite called diogenites. These samples were examined using an array of techniques, including precise analysis of certain elements for important clues to some of the Solar System's earliest chemical processing. Their work is published online July 22 by ...
