Fingertip pulse oximeters are widely available, inexpensive, and commonly used to make clinical decisions in many settings. Device performance is largely unregulated poorly characterised, especially people with dark skin pigmentation.
Abstract Background Point-of-care HIV viral load testing may enhance patient care and improve health services. We aimed to evaluate the feasibility acceptability of implementing such in a high-volume community sexual clinic United States. Methods conducted cross-sectional, mixed-methods study. Remnant venipuncture specimens from clients undergoing other screenings were analyzed using Xpert ® HIV-1 Viral Load assay. Results compared COBAS AmpliPrep/COBAS TaqMan Test. Clinical staff...
Some pulse oximeters perform worse in people with darker skin, and this may be due to inadequate diversity of skin pigment device development study cohorts. Guidance is needed accurately equitably characterize ensure research We tested multiple methods for characterizing assess comparability impact on cohort diversity.

Abstract The OpenOximetry Dataset stores clinical and lab pulse oximetry data. It supports measurements of arterial oxygen saturation (SaO2) by blood gas co-oximetry (SpO2), alongside processed unprocessed photoplethysmography (PPG) data other metadata. This includes skin color measurements, finger diameter, vital signs (e.g., pressure, end-tidal carbon dioxide), parameters acid-base balance, hemoglobin concentration). All data, from desaturation studies to trials, are collected...
Abstract Background Offering antiretroviral therapy (ART) to patients directly following an HIV diagnosis (“Rapid ART”) improves clinical outcomes and is feasible acceptable for providers. Despite this, implementation of Rapid ART not yet standard practice in the USA. Structural-level guidance available, but research at individual provider level that explores patient-provider interaction itself remains scarce. The Consolidated Framework Implementation Research (CFIR) provides a nuanced guide...
Background: Fingertip pulse oximeters are widely available, inexpensive, and commonly used to make clinical decisions in many settings. Device performance is largely unregulated poorly characterized, especially people with dark skin pigmentation. Methods: Eleven popular fingertip were evaluated using the US Food Drug Administration Guidance (2013) International Organization for Standardization Standards (2017) 34 healthy humans diverse pigmentation SaO2 plateaus between 70% 100%. Skin was...
Abstract The OpenOximetry Repository is a structured database storing clinical and lab pulse oximetry data, serving as centralized repository data model for initiatives. It supports measurements of arterial oxygen saturation (SaO2) by blood gas co-oximetry (SpO2), alongside processed unprocessed photoplethysmography (PPG) other metadata. This includes skin color measurements, finger diameter, vital signs (e.g., pressure, end-tidal carbon dioxide), parameters acid-base balance, hemoglobin...
In the general population, lower socioeconomic status (SES) associates with greater systemic and arterial inflammation a risk of cardiovascular disease. Because is heightened in individuals living HIV, we tested hypothesis that SES this population.Prospective cohort study.Men HIV were recruited. Arterial leukopoietic activity (ie, bone marrow activity) measured using 18F-fluorodeoxyglucose positron emission tomography/computed tomography. Zip code-level measures derived from US Census...
