Mitigating the impacts of Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) and substance use requires comprehensive and systematic thinking in designing interventions and developing policies. This study describes the growth of research publications from 1991 to 2021 in the Web of Science database and points out current research landscapes in the fields of HIV/AIDS and substance use. Latent Dirichlet Allocation was used for classifying 21 359 papers into corresponding topics. The most common topics were HIV transmission, HIV infection, quality of life and mental health of substance users, and the biomedical effect of substance use. Emerging research landscapes include vulnerabilities of people who inject drugs to HIV transmission and related health problems. This study found a lack of research on health services, interdisciplinary and inter-sectoral in combination with clinical evaluation and treatment services. Future investment and implementation of HIV/AIDS and substance use programs should focus on research of health services and clinical evaluation, especially context-specific interventions.

Nursing knowledge is housed in its paradigms, philosophies, models, and theories. This knowledge must be utilized to demark nursing's unique contributions within healthcare, regardless of the setting. The purpose of this paper is to explore the ways in which Parse's community model may serve as a way to think about health policies and the unique ways policies may connect to nursing knowledge. Within this paper, there is a discussion about health policy, Parse's humanbecoming paradigm, and policy development reflected upon with change concepts within the humanbecoming community model. This exploration is important because "disciplinary knowledge is the foundation for transforming health policy and health care delivery systems" (American Academy of Nursing, 2020, para. 1).

It is important to develop and implement policies that are unique to nursing practice situations. To do so, nurses must participate in policy development that connects disciplinary knowledge with policy formulation. The purpose of this paper is to explore connections between nursing knowledge and transitional care. This is done with a discussion of transitional care definitions and models, along with connections to concepts and principles within extant nursing theories and models. [ABSTRACT FROM AUTHOR]
