A stepped-wedge randomized trial protocol of a community intervention for increasing lung screening through engaging primary care providers (I-STEP).

Lung cancer screening with low-dose computed tomography (LDCT) reduces lung cancer mortality, yet few eligible high-risk patients receive it annually. This protocol describes a community-partnered intervention (Toolkit) designed to support primary care practices in making referrals for lung screening and guiding patients into appropriate screening pathways. This study uses a stepped-wedge implementation design.

Differences in Partner Services Outcomes for Men Who Have Sex With Men Diagnosed With Primary and Secondary Syphilis by HIV Serostatus.

Background: Differences in partner services outcomes in men who have sex with men (MSM) by HIV serostatus have not been explored as a potential driver of differential early syphilis (ES) burden in this population.

Methods: We compared partner services outcomes (number of partners named, notified, tested, diagnosed, and treated) between HIV-positive and HIV-negative MSM initiated for ES partner services in Texas from 2013 to 2016 using logistic regression and Wilcoxon-Mann-Whitney tests. Logistic regression was used to assess the relationship between HIV serostatus and having a no-partner-initiated (NPI) partner services interview controlling for demographic characteristics, prior partner services interactions, and geosocial phone application use.

Intracerebroventricular Oxytocin Self-Administration in Female Rats.

Oxytocin (OT) is a neuromodulator that facilitates pair-bonding, maternal care and social approach. OT is considered to promote these social behaviours by enhancing the salience and reinforcing effects of relevant social stimuli. There is the additional possibility that OT per se may be rewarding.

Testosterone enhances risk tolerance without altering motor impulsivity in male rats.

Anabolic-androgenic steroids (AAS) increase impulsive and uncontrolled aggressive ('roid rage) in humans and enhance agonistic behavior in animals. However, the underlying mechanisms for AAS-induced aggression remain unclear. Potential contributing elements include an increase risk-taking and/or motor impulsivity due to AAS.

Quality assurance management methods applied to a local-level primary health care system in rural Nigeria.

Introduction. Management of primary health care (PHC) systems in less developed countries is often impeded by factors such as poorly trained personnel, limited financial resources, and poor worker morale. This study explored the ability of local-level PHC supervisors in rural Nigeria to use quality assurance (QA) management methods to improve the quality of the PHC system.
