Background: Medication nonadherence is a public health issue that contributes to poor health outcomes and health-care costs. Factors influencing long-term medication adherence are known; however, little is known about short-course medication adherence.
Objective: This study examined patient perspectives on adherence and factors that influence adherence to short-course pharmacotherapy in diarrhea-predominant irritable bowel syndrome.
Method: Twenty-seven participants were interviewed to identify their perceptions of barriers and facilitators to thrice-daily, 14-day rifaximin.
Results: Participants were primarily female (89%), aged 18 to 65 years. Sixty-eight percent of interviewees were identified as "low-adherers," meaning the percentage of days with correct daily dosing of rifaximin was <80%. The final coding framework identified social/economic-related (family support and medication expense), system-related (relationship with provider and medication knowledge), condition-related (symptom severity), therapy-related (inconvenient dosing), and patient-related (forgetfulness and busyness of daily life) factors that influenced adherence.
Conclusion: The resulting patient perspectives highlight a diverse set of factors that influence short-course adherence and the need for tailored interventions that address these various factors resulting in enhanced patient outcomes.

Recent evidence indicates that endocrine resistance in estrogen receptor-positive (ER+) breast cancer is closely correlated with phenotypic characteristics of epithelial-to-mesenchymal transition (EMT). Nonetheless, identifying tumor tissues with a mesenchymal phenotype remains challenging in clinical practice. In this study, we validated the correlation between EMT status and resistance to endocrine therapy in ER+ breast cancer from a transcriptomic perspective.

Neurodegenerative diseases (NDDs) cause a progressive loss of neurons. Since NDDs are multifactorial, the precise etiology varies on the basis of the type of disease and patient history. Cohort studies and case studies have demonstrated a potential link between viral infections and the onset or progression of NDDs.

Cost-utility analysis of MR imaging-guided transurethral ultrasound ablation for the treatment of low- to intermediate-risk localised prostate cancer.
BMJ Open

Institute of Health Economics and Clinical Epidemiology, Faculty of Medicine and University Hospital of Cologne, Cologne, Germany
Background: Magnetic resonance-guided transurethral ultrasound ablation (MR-TULSA) is a new focal therapy for treating localised prostate cancer that is associated with fewer adverse effects (AEs) compared with established treatments. To support large-scale clinical implementation, information about cost-effectiveness is required.
Objective: To evaluate the cost-utility of MR-TULSA compared with robot-assisted radical prostatectomy (RARP), external beam radiation therapy (EBRT) and active surveillance (AS) for patients with low- to favourable intermediate-risk localised prostate cancer.
Modified Delphi Consensus on Interventions for Acute Radiation Dermatitis in Breast Cancer: A Canadian Expert Perspective.
Int J Radiat Oncol Biol Phys

McGill University, Oncology, Montreal, Quebec, Canada. Electronic address:
Acute radiation dermatitis (ARD) is a prevalent adverse effect of radiotherapy in patients with breast cancer, and there is a lack of high-quality data regarding its prevention and management. This study employs a systematic and iterative process to compile the perspectives of Canadian radiation oncology, nursing, and dermatology experts, aiming to establish consensus-based recommendations for the prevention and management of ARD in breast cancer patients. A modified Delphi consensus was conducted with the participation of 19 experts from across Canada.
