Summary
Targeted sampling effectively recruited street-based female sex workers for HIV research in the US. This method is valuable for reaching hidden, mobile populations in public spaces.
Area of Science:
- Public Health
- Epidemiology
- Social Sciences
Background:
- Effective HIV prevention interventions exist globally for street-based female sex workers (FSWs).
- There is a significant gap in US-based HIV prevention research specifically for street-based FSWs.
- Recruitment challenges hinder research among this hidden and mobile population in the USA.
Purpose of the Study:
- To describe the targeted sampling strategy used to recruit street-based FSWs in Baltimore, MD.
- To examine the influence of police presence on the HIV risk environment for street-based FSWs.
- To highlight the utility of targeted sampling for hidden populations.
Main Methods:
- Utilized targeted sampling to recruit a cohort of street-based FSWs.
- Focused on understanding the role of law enforcement in shaping HIV risk environments.
- Conducted research in Baltimore, Maryland.
Main Results:
- Targeted sampling proved to be an effective recruitment strategy.
- Demonstrated the feasibility of recruiting mobile and geographically dispersed hidden populations.
- Provided insights into the police's role in the HIV risk environment for FSWs.
Conclusions:
- Targeted sampling is a successful method for recruiting hidden populations like street-based FSWs.
- This approach can overcome recruitment barriers in US-based HIV prevention research.
- Understanding police influence is crucial for developing effective HIV interventions for FSWs.

109.0K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

01:28Infertility in Females
4.9K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

4.5K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

01:14Avoidance Learning and Learned Helplessness
2.6K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
