Background:

Imbalance in tryptophan (TRP) metabolism and its neuroactive metabolites, serotonin and kynurenine (KYN), is a known pathogenic mechanism underlying neurocognitive impairment. Gut microbiota plays an important role in TRP metabolism, and the production of these neuroactive molecules affects neurocognitive function. Although both HIV infection and normal aging independently induce gut dysbiosis and influence TRP metabolism, their interactive effects on compositional/functional changes in gut microbiota and consequent alterations in TRP metabolites remain largely undetermined.

Methods:

Older people living with HIV infection (PLWH, aged 50–70 years, n = 22) were enrolled in this cross-sectional pilot study. Metagenomic analysis of fecal microbiome …

Voices From The Field: A Qualitative Study Of The Challenges And Promising Practices Of Rural Public Health In Addressing Hiv And Hepatitis C, Martha Elbaum Williamson Mpa, Karen B. Pearson Mlis, Ms, Amanda R. Burgess Mppm, Jennifer D. Lenardson Mhs, Erika C. Ziller Phd

Population Health

Rural areas of the United States may be vulnerable to an HIV or hepatitis C (HCV) outbreak among persons who inject drugs. Researchers at the University of Southern Maine’s Rural Health Research Center examined the capacity of rural public health systems to prepare for, identify, control, and respond to an HIV or HCV outbreak. Through semi-structured interviews with 36 state and local public health professionals from six rural states, we sought to understand the challenges related to HIV, HCV, and serving rural persons who inject drugs and to identify strategies to address those challenges. Challenges limiting the public health capacity …

Multilevel Analysis Of Individual, Neighborhood, And Health Care Facility Characteristics Associated With Achievement And Maintenance Of Hiv Viral Suppression Among Persons Newly Diagnosed With Hiv In New York City, Ellen W. Wiewel

Dissertations, Theses, and Capstone Projects

Objective

To investigate the effect of individual, health care facility, and neighborhood characteristics on achievement and maintenance of HIV viral suppression, among New York City residents aged 13 years and older diagnosed with HIV between 2006 and 2012.

Methods

I used individual-level data from the New York City HIV surveillance registry and Case Surveillance-Based Sampling, facility-level data from the surveillance registry, and neighborhood-level data from the U.S. Census and American Community Survey. The outcomes of interest were first viral suppression after diagnosis (Aims 1 and 3; ≤400 copies/mL) and virologic failure after first suppression among persons who achieved suppression (Aim …

Comparison Of Need And Supply Of Syringes For Therapeutic Injections In Pakistan, Adnan Ahmad Khan, Momina Saleem, Huma Qureshi, Rashid Jooma, Ayesha Khan

Section of Neurosurgery

Objectives: To determine the extent of shortfall in syringes by measuring the need from nationally validated sources and comparing it with position on the supply side. This was done in order to contribute to the ongoing national discussions that have focused on increasing syringe supply to curtail syringe reuse.
Methods: Using 'Injections received' data from the Pakistan Demographic Health Survey 2006-7 (N: 5429) and the National Hepatitis Survey (N: 47,043), the study estimated the number of injections received in Pakistan. We matched these against the local syringe production figures from the syringe manufacturers' association and import figures from the Federal …
