Background: Acceptability and tolerance of bowel preparation is critical to overcome patient hesitancy in undergoing colon cancer screening and surveillance colonoscopy. To improve patient experience, a new sports drink-flavored bowel preparation containing polyethylene glycol (PEG) and sulfate salts (FPSS) was developed to provide a similar experience to a commonly used but not United States Food and Drug Administration (FDA) approved PEG and sports drink bowel preparation (PEG-SD), while also achieving improved cleansing efficacy.

Methods: This FPSS preparation, approved by the FDA in June 2023, was evaluated in a non-randomized Phase 2 study in which 40 patients requiring colonoscopy were prepared with FPSS and 20 with PEG-SD.

Introduction: A new bowel preparation for colonoscopy has been developed containing poorly absorbed sulfate salts and polyethylene glycol 3350, which retain water within the intestinal lumen resulting in copious diarrhea, thereby cleansing the bowel. The product was formulated to be safe and effective with a sports drink-like flavor. This study evaluated the new flavored polyethylene glycol and sulfate solution (FPSS) compared with a Food and Drug Administration-approved bowel preparation containing sulfate salts only [oral sulfate solution (OSS)].

Remote ischaemic preconditioning (RIPC) using transient limb ischaemia failed to improve clinical outcomes following cardiac surgery and the reasons for this remain unclear. In the ERIC-GTN study, we evaluated whether concomitant nitrate therapy abrogated RIPC cardioprotection. We also undertook a post-hoc analysis of the ERICCA study, to investigate a potential negative interaction between RIPC and nitrates on clinical outcomes following cardiac surgery.

Introduction: A new tablet-based bowel prep for colonoscopy has been developed containing poorly absorbed sulfate salts which act to retain water within the intestinal lumen resulting in a copious diarrhea, thereby cleansing the bowel. This study evaluated the safety and efficacy of these oral sulfate tablets (OST) compared with a US FDA-approved bowel prep solution containing PEG3350, electrolytes, and ascorbate (polyethylene glycol and ascorbate [PEG-EA]).

Methods: Five hundred fifteen adult patients (mean 57y) were enrolled in this single-blind, multicenter, noninferiority study.

Objectives: The objectives of this study were to critically evaluate the methodology and conclusions of the fiscal notes prepared by the state of Missouri for including doctors of chiropractic (DCs) under Missouri Medicaid and to develop a dynamic scoring model that calculates the savings if DCs were allowed to offer treatment under Missouri Medicaid.

Methods: We used a secondary analysis to determine the cost-saving assumptions to be incorporated into a dynamic model. We reviewed the literature on efficiency and effectiveness of DC-delivered care regarding the most reliable assumptions concerning cost savings and utilization.

Purpose: The theory of attachment has informed our understanding of survival and well-being throughout the lifespan. There is a growing interest in the relationship between attachment and symptoms of post-traumatic stress (PTS). Emerging evidence points to important links between attachment and PTS, yet current theoretical and clinical understandings of PTS symptoms and attachment remain relatively disparate.

The adverse social and physical conditions of homelessness pose significant developmental risks for children, which may be compounded or buffered by the quality of parenting behaviour they are exposed to. There is currently a limited understanding of how parents approach their care-giving role and responsibilities while adjusting to the experience of homelessness. Advancing knowledge in this area is essential for developing acceptable, appropriate and effective interventions to support highly marginalised and vulnerable homeless families.

The irregular appearance of planktonic algae blooms off the coast of southern California has been a source of wonder for over a century. Although large algal blooms can have significant negative impacts on ecosystems and human health, a predictive understanding of these events has eluded science, and many have come to regard them as ultimately random phenomena. However, the highly nonlinear nature of ecological dynamics can give the appearance of randomness and stress traditional methods-such as model fitting or analysis of variance-to the point of breaking.

Anthracycline chemotherapy maintains a prominent role in treating many forms of cancer. Cardiotoxic side effects limit their dosing and improved cancer outcomes expose the cancer survivor to increased cardiovascular morbidity and mortality. The basic mechanisms of cardiotoxicity may involve direct pathways for reactive oxygen species generation and topoisomerase 2 as well as other indirect pathways.

Antimicrobial chemotherapy now spans 80 years and four generations. The healthcare epidemiologist has an important role to play in this field. Efforts focus in three areas: (i) minimizing the transmission of antimicrobial-resistant bacteria in healthcare settings (infection control); (ii) optimizing use of currently available antibacterial drugs (antibiotic stewardship); and (iii) recognizing and responding to opportunities for new drug development.

Objectives: Sickle cell disease (SCD) is the UK's most common blood disorder causing sickle shaped red blood cells to block small blood vessels inducing both acute and chronic pain. A crucial factor in determining quality of life for those with SCD is the severity, timing and number of painful sickling episodes. However, little research focuses on the nature of pain and so it is poorly understood.

Background: Despite the long history of psychogenic nonepileptic seizures (PNES), relatively little is known about the mechanisms that cause and maintain this condition. Emerging research evidence suggests that patients with PNES might have difficulties in regulating their emotions. However, much remains to be learned about the nature of these difficulties and the emotional responses of individuals with PNES.
