How Diet May Alter Risk of Periodontal Disease

Mar. 24, 2021

Can your overall diet, or specific foods, affect your risk for periodontal (gum) disease? The answer has major public health implications, since periodontal disease affects 47% of adults over the age of 30 in the United States and has an indirect economic cost of over $123 billion.

Health Screening for Emerging and Non-Communicable Disease Burdens Among the Global Poor

Research Brief
Jan. 26, 2021

Among adults in rural Malawi, population health screening for high blood pressure (BP) led to a 22-percentage point drop in the likelihood of being hypertensive four years later. Individuals with elevated BP received a referral letter upon initial screening; at follow-up, they had lower BP and higher self-reported mental health than individuals with similar BP who were just below the threshold for referral. Population health screenings can reduce the burden of non-communicable diseases in low-income countries.

Clarifying the Role of the Modern General Surgeon: The Effect of Specialization on Inpatient Practice Patterns in General Surgery

Jan. 13, 2021

Catherine L. Mavroudis, Christopher Wirtalla, Jason Tong, Ezra S. Brooks, Cary B. Aarons, Rachel R. Kelz

Abstract [from journal]

Objective: The growing concentration of fellowship-trained and integrated residency-trained subspecialty surgeons has encroached on the breadth and volume of a so-called "true" general surgery practice, leaving the role of new general surgeons in flux. We aimed to describe the surgical practice of new general surgeons with and without subspecialty fellowship training.

Design: In this retrospective cohort study, state discharge data was linked to American Medical Association Masterfile and

Predicting Survival After Liver Transplantation in Patients With Hepatocellular Carcinoma Using the LiTES-HCC Score

David Goldberg, Alejandro Mantero, Craig Newcomb, Cindy Delgado, Kimberly A. Forde, David E. Kaplan, Binu John, Nadine Nuchovich, Barbara Dominguez, Ezekiel EmanuelPeter P. Reese

Abstract [from journal]

Background & aims: Liver transplant priority in the US and Europe follows the 'sickest-first 'principle. However, for patients with hepatocellular carcinoma (HCC), priority is based on binary tumor criteria (e.g., Milan) to expedite transplant for patients with 'acceptable' post-transplant outcomes. Newer risk scores developed to overcome limitations of these binary criteria (e.g., Metroticket, HALT-HCC) are insufficient to be used for waitlist priority as they focus solely on HCC-related pre-transplant variables

Prior Sexually Transmitted Infection and Human Immunodeficiency Virus Risk Perception in a Diverse At-Risk Population of Men Who Have Sex with Men and Transgender Individuals

Jan. 4, 2021

Daniel Resnick, Knashawn Morales, Robert Gross, Danielle Petsis, Danielle Fiore, Annet Davis-Vogel, David Metzger, Ian Frank, Sarah Wood

Abstract [from journal]

Prior sexually transmitted infections (STIs) are associated with higher rates of subsequent human immunodeficiency virus (HIV) infection, but the influence of prior STIs on perceived vulnerability to HIV remains unclear. We aimed to assess this relationship, hypothesizing that a prior STI diagnosis is associated with higher self-assessed vulnerability to HIV. We performed a cross-sectional study of men and transgender individuals who have sex with men screening for HIV prevention trials in Philadelphia. An unadjusted regression

Abstract [from journal]

Identifying effective strategies to promote healthy eating and reduce obesity is a priority in the USA, especially among low-income and minority groups, who often have less access to healthy food and higher rates of obesity. Efforts to improve food access have led to more supermarkets in low-income, ethnically diverse neighborhoods. However, this alone may not be enough to reduce food insecurity and improve residents' diet quality and health. This paper summarizes the design, methods, baseline findings, and supermarket in-store

Increasing HIV Testing and Viral Suppression via Stigma Reduction in a Social Networking Mobile Health Intervention Among Black and Latinx Young Men and Transgender Women Who Have Sex With Men (HealthMpowerment): Protocol for a Randomized Controlled Trial

Dec. 16, 2020

Abstract [from journal]

Background: Stigma and discrimination related to sexuality, race, ethnicity, and HIV status negatively impact HIV testing, engagement in care, and consistent viral suppression (VS) among young Black and Latinx men who have sex with men and transgender women who have sex with men (YBLMT). Few interventions address the effects of intersectional stigma among youth living with HIV and those at risk for HIV within the same virtual space.

Objective: Building on the success of the HealthMpowerment (

COVID-19 Screening Strategies for Repopulating College Campuses

Dec. 9, 2020

As some college and university leaders plan to resume in-person instruction this spring, it is critical to determine the best way to identify COVID-19 cases among students to safely repopulate campuses. However, there is a lack of consensus about the optimal testing strategy to identify the most infections.
