Women and HIV: A story of racial and ethnic health disparities

The history of women with HIV/AIDS in the United States is really a story of racial and ethnic health disparities.

Overall, the rate of American women contracting the disease relative to men has climbed from 8 percent in the 1980s to 25 percent today. But most of this burden is in underserved communities: one in 32 African-American women will be diagnosed with HIV in their lifetime, as will one in 106 Latina women. Meanwhile, one in 526 Caucasian and Asian women will contract the virus. Death rates are also higher for African-American and Latina women, making it one of the leading causes of death for those groups. (more…)

Epidemiology and gene sequencing technologies have been used by researchers in the UK, the Kingdom of Saudi Arabia, the US and Canada to show that the novel Middle East Respiratory Syndrome (MERS) coronavirus can spread between people in healthcare settings. The work is published in the New England Journal of Medicine.

The scientists, from the Saudi Arabian Ministry of Health, UCL, Wellcome Trust Sanger Institute, University of Toronto, University of Colorado and Johns Hopkins University, rapidly investigated and defined the epidemiology, transmission dynamics and genetic composition of the MERS-CoV cluster of 22 cases of healthcare-acquired MERS coronavirus infections from a recent outbreak in Al-Hasa, Eastern Province, Kingdom of Saudi Arabia.

Evidence from a quiet MRI: Breastfeeding benefits babies’ brains

A study using brain images from “quiet” MRI machines adds to the growing body of evidence that breastfeeding improves brain development in infants. Breastfeeding alone produced better brain development than a combination of breastfeeding and formula, which produced better development than formula alone.

PROVIDENCE, R.I. [Brown University] — A new study by researchers from Brown University finds more evidence that breastfeeding is good for babies’ brains.

The study made use of specialized, baby-friendly magnetic resonance imaging (MRI) to look at the brain growth in a sample of children under the age of 4. The research found that by age 2, babies who had been breastfed exclusively for at least three months had enhanced development in key parts of the brain compared to children who were fed formula exclusively or who were fed a combination of formula and breastmilk. The extra growth was most pronounced in parts of the brain associated with language, emotional function, and cognition, the research showed. (more…)

Innovative intervention program improves life for rural women in India living with HIV/AIDS

A multidisciplinary team of researchers from UCLA and India has found that a new type of intervention program, in which lay women in the rural Indian province of Andra Pradesh were trained as social health activists to assist women who have HIV/AIDS, significantly improved patients’ adherence to antiretroviral therapy and boosted their immune-cell counts and nutrition levels.

The lay women were trained by the research team to serve as accredited social health activists, or ASHA, and their work was overseen by rural nurses and physicians. These ASHA then provided counseling and support to the women with HIV/AIDS, as well as assistance aimed at removing the barriers they face in accessing health care and treatment. (more…)

Breaking Dengue Fever

Like malaria, dengue fever is an infectious disease transmitted by mosquitoes. Unlike malaria, there is no vaccine for it. As many as 100 million people contract dengue each year, but MSU researcher Zhiyong Xi is working to change that.

Among the estimated 2.5 billion people at risk for dengue, more than 70 percent live in Asia Pacific countries, which spurred Xi to establish a collaborative research institute at Sun Yat-sen University in Guangzhou, China. (more…)

Health in conflict: A public health student undertakes a challenging internship in Lebanon

“In Syria it is a fast death; here it is a slow death,” a woman lamented as she described her situation as a refugee in Lebanon escaping an escalating civil war in her homeland.

Each woman’s story was different, but they were all sad, grim. Another refugee had five children and a husband who is detained somewhere back home. “When a father is present you might be able to afford some of the children’s needs, but if he’s not, from whom do you seek help?” she asked. (more…)

More Fresh Air in Classrooms Means Fewer Absences

Berkeley Lab study finds correlation between higher illness absences and lower ventilation rates in California elementary schools.

If you suspect that opening windows to let in fresh air might be good for you, a new study by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has confirmed your hunch. Analyzing extensive data on ventilation rates collected from more than 150 classrooms in California over two years, the researchers found that bringing classroom ventilation rates up to the state-mandated standard may reduce student absences due to illness by approximately 3.4 percent.

Vicious cycle: Changes in brain chemistry sustain obesity

In a new discovery reported in the Journal of Biological Chemistry, Brown University and Lifespan researchers show that in the brain cells of rats, obesity impedes the production of a hormone that curbs appetite and inspires calorie burning. The root cause appears to be a breakdown in the protein-processing mechanism of the cells. In the lab, the researchers showed they could fix the breakdown with drugs. (more…)
