Difficulty With Board Certification in Urology Is Associated With Adverse Medical License Actions.

Introduction: Board certification in urology is a multistep process including a written qualifying examination (QE), followed by an oral certifying examination (CE) approximately 2 years after residency or fellowship completion. The goal of this process is to ensure that urologists are well trained, have an extensive fund of knowledge, demonstrate professionalism and competence in practice, and are safe to practice urology. Board certification in urology serves to both establish and confirm physician competence and ultimately protect the public.

Increases in the susceptibility of human endometrial CD4 T cells to HIV-1 infection post-menopause are not dependent on greater viral receptor expression frequency.

Epidemiological evidence suggests that post-menopausal women are more susceptible to HIV infection following sexual intercourse than are younger cohorts for reasons that remain unclear. Here, we evaluated how menopause-associated changes in CD4 T cell numbers and subsets as well as HIV coreceptor expression, particularly CCR5, in the endometrium (EM), endocervix (CX), and ectocervix (ECX) may alter HIV infection susceptibility. Using a tissue-specific mixed cell infection model, we demonstrate that while no changes in CD14 macrophage infection susceptibility were observed, CD4 T cell HIV-1 infection frequency increases following menopause in the EM, but not CX nor ECX.

Guidelines International Network: Principles for Use of Artificial Intelligence in the Health Guideline Enterprise.

Description: Artificial intelligence (AI) has been defined by the High-Level Expert Group on AI of the European Commission as "systems that display intelligent behaviour by analysing their environment and taking actions-with some degree of autonomy-to achieve specific goals." Artificial intelligence has the potential to support guideline planning, development and adaptation, reporting, implementation, impact evaluation, certification, and appraisal of recommendations, which we will refer to as "guideline enterprise." Considering this potential, as well as the lack of guidance for the use of AI in guidelines, the Guidelines International Network (GIN) proposes a set of principles for the development and use of AI tools or processes to support the health guideline enterprise.

White matter connections within the central sulcus subserving the somato-cognitive action network.

The somato-cognitive action network (SCAN) consists of three nodes interspersed within Penfield's motor effector regions. The configuration of the somato-cognitive action network nodes resembles the one of the 'plis de passage' of the central sulcus: small gyri bridging the precentral and postcentral gyri. Thus, we hypothesize that these may provide a structural substrate of the somato-cognitive action network.
