Summary
Sociodemographic factors like income, race, and political affiliation significantly impact HIV pre-exposure prophylaxis (PrEP) use. Understanding these disparities is crucial for equitable PrEP access and the Ending the HIV Epidemic initiative.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- HIV pre-exposure prophylaxis (PrEP) is a critical component of the Ending the HIV Epidemic initiative in the U.S.
- Understanding factors influencing PrEP uptake is essential for addressing HIV disparities.
Purpose of the Study:
- To evaluate the association between sociodemographic factors and PrEP use in U.S. jurisdictions with high HIV diagnosis rates.
- To identify disparities in PrEP utilization based on income, race, political affiliation, and geographic location.
Main Methods:
- Utilized data from AIDSVu, U.S. Census Bureau, and MIT Election Lab for years 2012-2019.
- Employed linear mixed-effects modeling for county-level analysis and correlational analysis for state-level PrEP rates.
- Examined associations with year, HIV diagnoses, income, insurance coverage, political affiliation, race, and geography.
Main Results:
- Significant associations were found between sociodemographic factors (income, race, political affiliation) and PrEP use at both county and state levels.
- Identified disparities in PrEP utilization across different demographic groups and geographic areas.
Conclusions:
- Sociodemographic factors play a significant role in the equitable provision and uptake of PrEP.
- Further investigation into policy differences contributing to PrEP inequity is necessary to improve access and reduce HIV transmission.

01:24Factors Influencing Drug Absorption: Presystemic Elimination
176
The pharmacokinetic journey of oral drugs begins with a crucial first pass through the hepatic portal system, called the first-pass effect. This first pass significantly impacts bioavailability — the proportion of a drug that enters systemic circulation and is available for therapeutic action. The primary route sees the drug absorbed by intestinal membranes and then shunted to the liver via the hepatic portal vein. Here, pre-systemic elimination occurs as drugs face metabolism or biliary...

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Protein-drug binding, a pivotal aspect of pharmacokinetics, is subject to considerable variability influenced by an array of patient-related factors. The intricate interplay of age, individual differences, and pathological conditions significantly impact the binding dynamics and subsequent pharmacological effects.
Age stands as a key determinant in protein-drug binding. Neonates, characterized by low albumin content, experience heightened concentrations of unbound drugs such as phenytoin and...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...
