Researchers use a variety of population size estimation methods to determine the sizes of key populations at elevated risk of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), an important step in quantifying epidemic impact, advocating for high-risk groups, and planning, implementing, and monitoring prevention, care, and treatment programs. Conventional procedures often use information about sample respondents' social network contacts to estimate the sizes of key populations of interest. Recent work proposes a generalized network scale-up method that combines two samples - a traditional sample of the general population and a link-tracing sample of the hidden population - and produces more accurate results with fewer assumptions than conventional approaches.

We consider causal inference in observational studies with choice-based sampling, in which subject enrollment is stratified on treatment choice. Choice-based sampling has been considered mainly in the...
Precarious employment (PE) is a social determinant of poor health of workers. However, this population usually lack a sampling frame, making it challenging to identify the characteristics of this grou...
We developed a method to estimate population abundance from simultaneous counts of unmarked individuals over multiple sites. We considered that at each sampling occasion, individuals in a population c...
Adolescent girls and young women (AGYW) remain underserved and at risk for HIV acquisition in Ethiopia. However, there is significant risk heterogeneity among AGYW with limited consensus on optimal st...
Many species have a dormant stage in their life cycle, including seeds for plants. The dormancy stage influences the species dynamics but is often undetectable. One way to include dormancy is to model...
The study purpose is to collect images and user feedback from the Next Generation Venue Ultrasound system, components, and accessories under clinical conditions, as required for device dev...
The aim of this cross-sectional study is to evaluate the hidden blood loss in patients who underwent open radical hysterectomy and identity its risk factors.
Indigenous youth are disproportionately represented in new HIV infection rates in Canada. Limited studies have evaluated longitudinal effects of arts-based approaches to HIV prevention wit...
The purpose of the study is to collect images data sets from clinical cases and periodic user feedback on the Next Generation Venue ultrasound system under clinical conditions. This is a m...
A sample of 600 young (15-25) men who have sex with men (MSM) and transgender persons living in South-East Michigan's Detroit Metro Area (DMA) will be recruited through venue-based samplin...
A sampling methodology using small sample sizes when conducting surveys in small geographical or population-based areas or lots.
Studies in which a number of subjects are selected from all subjects in a defined population. Conclusions based on sample results may be attributed only to the population sampled.
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
A process that searches for hidden and important connections among information embedded in published literature.
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
AIDS and HIV
AIDS; Acquired Immune Deficiency Syndrome. HIV; Human Immunodeficiency Virus HIV infection causes AIDS. HIV infection also causes the production of anti-HIV antibodies, which forms the test for HIV in patients. People who have the HIV antibodies are ...
