Tuesday, October 8th, 2pm-3pm

Artificial Intelligence is being called the new electricity—a technological invention that promises to transform our lives and the world. The resurgence of investment and enthusiasm for artificial intelligence, or the ability of machines to carry out “smart” tasks, is driven largely by advancements in the subfield of machine learning. Machine learning algorithms can analyze large volumes of complex data to find patterns and make predictions, often exceeding the accuracy and efficiency of people who are attempting the same task. Driven by tremendous growth in data collection and availability as well as computing power and accessibility, artificial intelligence and machine learning applications are rapidly growing in public health.

This presentation reviewed emerging application and implications of machine learning in public health research. The aim of this seminar was to increase participants’ understanding of machine learning, its relevance to public health research and practical challenges to its application, so as to enable participants to work in conjunction with people with technical skills in machine learning. We outlined what can and cannot be solved with machine learning models and provide a basic overview of machine learning techniques and their use.

The CHIPTS’ Methods Core hosts a monthly seminar series, which are one-hour workshops on research and statistical methods.  The seminars are open to HIV researchers, faculty, students, and community. To see previous seminars, check out the Methods Seminar tag or you can find seminar videos on our Youtube Channel! This series is hosted by the Center for HIV Identification, Prevention, and Treatment Services (CHIPTS) and made possible by funds from the National Institute of Mental Health (MH058107).

Spotlight: Dilara Uskup, PhD, PhD

Dilara Üsküp began working on HIV/AIDS as an undergraduate at the University of Michigan, Ann Arbor. As part of  Dr. Nesha Haniff’s Pedagogy of the Action program, she taught Dr. Haniff’s peer health HIV module to individuals who were low-literate and illiterate in South Africa. Upon graduating early from the Gerald R. Ford School of Public Policy at Michigan, Dilara directed her efforts on addressing race and gender-related HIV related disparities at the federal level. As an intern in the Office of National AIDS Policy (ONAP) at the White House, she observed that the federal government lacked a comprehensive strategy to specifically address gender and race-based health disparities in the domestic fight against the HIV/AIDS epidemic. Dilara led the effort to co-author a presidential memorandum, entitled “Establishing a Working Group on the Intersection of HIV/AIDS, Violence Against Women and Girls, and Gender-related Health Disparities,” that was then signed by former President Barack Obama in March 2012.

Dilara earned a PhD in theology and a PhD in political science from the University of Chicago. Her research empowers women to optimize their sexual health through a multidisciplinary approach at the intersection of health behavior, social science, and religion. Currently, she is working on several projects including the incorporation of technology into PrEP delivery and increasing PrEP access among African American women. Dilara is also committed to dismantling institutionalized racism in the health care setting and addressing racial and ethnic disparities in the health. Dilara is a Turkish-African American, and one of her personal life goals is mastering her family’s prized rice pilaf and börek recipes. As a self-identified creative-trapped-in-an-academic’s-body Dilara hopes to complete her fantasy fiction novel, pursue her photography, and other concept creations.

U.S. Preventive Services Task Force Issues Final Recommendation Statements on HIV Screening and HIV Prevention

Clinicians should screen for HIV in adolescents, adults, and pregnant people and offer PrEP to people at high risk for HIV. You can find the original recommendation available for download here: U.S. Preventive Services Task Force Issues Final Recommendation Statements on HIV Screening and HIV Prevention

WASHINGTON, D.C. – June 11, 2019 – The U.S. Preventive Services Task Force (Task Force) today published final recommendation statements on HIV screening and HIV prevention. Based on its review of the evidence, the Task Force recommends that clinicians screen for HIV in everyone ages 15 to 65 years and all pregnant people. Younger adolescents and older adults at increased risk for HIV should also be screened. The Task Force also recommends that clinicians offer pre-exposure prophylaxis (PrEP)—a pill that helps prevent HIV—to people at high risk of HIV. These are A recommendations.

HIV is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases. HIV is spread by contact with certain bodily fluids of a person infected with HIV, most commonly during sex without a condom or through injection drug use. HIV continues to be a significant public health issue; about 40,000 people are diagnosed with HIV each year. While HIV infection rates have been going down, rates among some groups are on the rise, most notably among young adults. “Clinicians can make a real difference toward reducing the burden of HIV in the United States,” says Task Force chair Douglas K. Owens, M.D., M.S. “HIV screening and HIV prevention work to reduce new HIV infections and ultimately save lives.”

Screening for HIV

Screening is the only way to know if a person has been infected with HIV because, after initial flu-like symptoms, HIV does not cause any signs or symptoms for several years. The Task Force recommends HIV screening for everyone between the ages of 15 and 65 and for anyone who is pregnant. People younger than 15 and older than 65 who are at increased risk for HIV should also be screened. Behaviors that increase someone’s risk include having a new sex partner whose HIV status is unknown.

“Screening for HIV is important so that everyone knows their HIV status, and those with HIV can begin treatment right away,” says Task Force member John Epling, M.D., M.S.Ed. “Today’s treatments help people live long, healthy lives and lower the risk of passing HIV to others.”

People who learn that they have HIV need to start treatment as soon as possible to suppress the virus (keep the amount of HIV in the blood very low) and prevent HIV-related disease. Treatment also helps to reduce the chance that someone with HIV can pass the infection to another person, including pregnant people passing it on to their baby.

PrEP for HIV Prevention

In addition to screening, people need to take steps to prevent getting HIV by using condoms during sex and, for those who inject drugs, using clean needles and syringes. People at high risk for HIV have an additional strategy for prevention: taking PrEP. The Task Force found that PrEP is highly effective at preventing HIV, if taken daily. Taking PrEP less often lowers its effectiveness. Like with many medicines, there are benefits and harms of use. For people at high risk of getting HIV, the benefits of PrEP far outweigh the harms, which can include kidney problems and nausea.

PrEP is not for everyone; it is for people who do not have HIV but are at high risk for getting it. Behaviors that can put someone at high risk include having a sex partner who is living with HIV, having sex without a condom with a partner whose HIV status is unknown and who is at high risk for HIV, and sharing injection drug equipment.

“Clinicians have the opportunity to protect patients at high risk for HIV by offering PrEP,” says Task Force member Seth Landefeld, M.D. “To know which patients are good candidates for PrEP, clinicians need to ask all patients about their sexual history and injection drug use in an open and nonjudgmental way.” Clinicians should also provide support to patients taking PrEP to help them follow the daily regimen for maximum protection.

PrEP only helps prevent HIV. People who take PrEP should continue to use condoms and practice other behaviors to reduce their risk of other sexually transmitted infections.

The Task Force’s final recommendation statements and corresponding evidence summaries have been published online in the Journal of the American Medical Association and posted on the Task Force Web site. Draft versions of these recommendations and evidence reviews were available for public comment from November 20, 2018, to December 26, 2018.

The Task Force is an independent, volunteer panel of national experts in prevention and evidence based medicine that works to improve the health of all Americans by making evidence-based recommendations about clinical preventive services such as screenings, counseling services, and preventive medications.

Dr. Owens is a general internist and investigator at the Center for Innovation to Implementation at the Veterans Affairs Palo Alto Health Care System. He is the Henry J. Kaiser, Jr., professor at Stanford University, where he is also a professor of medicine.

Dr. Epling is a professor of family and community medicine at the Virginia Tech Carilion School of Medicine in Roanoke, VA. He is the medical director of research for family and community medicine, is the medical director of employee health and wellness for the Carilion Clinic, and maintains an active clinical primary care practice.

Dr. Landefeld is the chairman of the Department of Medicine and the Spencer chair in medical science leadership at the University of Alabama at Birmingham School of Medicine. Dr. Landefeld also serves on the board of directors of the American Board of Internal Medicine.
