Background: The clinical burden of Long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and other post-infectious fatiguing illnesses (PIFI) is increasing. There is a critical need to advance understanding of the effectiveness and sustainability of innovative approaches to clinical care of patients having these conditions.

Methods: We aim to assess the effectiveness of a Long COVID and Fatiguing Illness Recovery Program (LC&FIRP) in a two-arm, single-blind, pragmatic, quality improvement, professional cluster, randomized controlled trial in which 20 consenting clinicians across primary care clinics in a Federally Qualified Health Center system in San Diego, CA, will be randomized at a ratio of 1:1 to either participate in (1) weekly multi-disciplinary team-based case consultation and peer-to-peer sharing of emerging best practices (i.

Background: Monoclonal antibody (mAb) treatment for COVID-19 is associated with improved clinical outcomes. However, there is limited information regarding the impact of treatment on symptoms and the prevalence of post-COVID Conditions (PCC). Understanding of the association between time to mAb infusion and the development of PCC is also limited.

During April 2020-August 2020, a preemptive testing strategy combined with accessible isolation and symptom screening among people experiencing homelessness in congregant living settings in San Diego, California, contributed to a low incidence proportion of coronavirus disease 2019 (0.9%). Proactively addressing challenges specific to a vulnerable population may prove impactful.

Purpose: Tobacco cessation remains a public health priority. Unassisted quits are most common despite evidence for a combination of guideline-recommended strategies. This paper reports findings from a pilot study designed to assess past quit strategies and tobacco users' receptiveness to using an integrative clinic that offers both conventional and alternative treatments for future cessation attempts.

Introduction: While many medications can be effective aids to quitting tobacco, real world adherence to smoking cessation medications may render a potentially effective medication ineffective. The present study investigated the role of adherence on treatment outcomes in a bupropion dose-response study among adolescent smokers trying to quit smoking.

Methods: Three hundred twelve adolescent boys (n = 143) and girls (n = 169) between the ages of 14-17 were enrolled in the study, and were randomly assigned to use either 300 mg, 150 mg or placebo bupropion to quit smoking.

Background: Complementary and alternative medicine (CAM) use has steadily increased globally over the past two decades and is increasingly playing a role in the healthcare system in the United States. CAM practice-based effectiveness research requires an understanding of the settings in which CAM practitioners provide services. This paper describes and quantifies practice environment characteristics for a cross-sectional sample of doctors of chiropractic (DCs), licensed acupuncturists (LAcs), and licensed massage therapists (LMTs) in the United States.

Background: Practitioners of complementary and alternative medicine (CAM) therapies are an important and growing presence in health care systems worldwide. A central question is whether evidence-based behavior change interventions routinely employed in conventional health care could also be integrated into CAM practice to address public health priorities. Essential for successful integration are intervention approaches deemed acceptable and consistent with practice patterns and treatment approaches of different types of CAM practitioners - that is, they have context validity.

Objective: To evaluate the effect of tobacco cessation brief-intervention (BI) training for lay "health influencers," on knowledge, self-efficacy and the proportion of participants reporting BI delivery post-training.

Methods: Randomized, community-based study comparing In-person or Web-based training, with mailed materials.

Results: In-person and Web-training groups had significant post-training cessation knowledge and self-efficacy gains.

Background: Quitlines and worksite-sponsored cessation programs are effective and highly accessible, but limited by low utilization. Efforts to encourage use of cessation aids have focused almost exclusively on the smoker, overlooking the potential for friends, family, co-workers, and others in a tobacco user's social network to influence quitting and use of effective treatment.

Methods: Longitudinal, observational pilot feasibility study with 6-week follow-up survey.

Improving population health requires understanding and changing societal structures and functions, but countervailing forces sometimes undermine those changes, thus reflecting the adaptive complexity inherent in public health systems. The purpose of this paper is to propose systems thinking as a conceptual rubric for the practice of team science in public health, and transdisciplinary, translational research as a catalyst for promoting the functional efficiency of science. The paper lays a foundation for the conceptual understanding of systems thinking and transdisciplinary research, and will provide illustrative examples within and beyond public health.

Objective: To evaluate the effectiveness of the Nicotrol nicotine inhaler as an aid to smoking cessation in over-the-counter (OTC) versus health-care-provider (HCP) conditions.

Methods: Five hundred twenty healthy smokers were randomized to the treatment conditions and followed for a year.

Results: At most follow-up visits, abstinence rates for the HCP group were 2 to 3 times those observed in the OTC group.
