Designing a blockchain technology platform for enhancing the pre-exposure prophylaxis care continuum.

Objectives: Pre-exposure prophylaxis (PrEP) is a key biomedical intervention for ending the HIV epidemic in the United States, but its uptake is impeded by systemic barriers, including fragmented workflows and ineffective data coordination. This study aims to design PrEPLinker, a blockchain-based, client-centered platform to enhance care to address these challenges by improving care coordination and enabling clients to securely manage their identity and PrEP-related data.

Materials And Methods: Using Houston, Texas, as a use case, we conducted a needs assessment with PrEP collaborators to evaluate existing workflows and identify barriers in the PrEP care continuum.

How do researchers identify and recruit dementia caregivers? A scoping review.

Background And Objectives: Studies involving dementia caregivers are essential to transform care and inform new policies. However, identifying and recruiting this population for research is an ongoing challenge. This scoping review aimed to capture the current methodology for identifying and recruiting dementia caregivers in clinical studies.

"I didn't go into medicine just to be on the phone": Emotional Expression as Sacrosanct During Derious Illness Patient-Physician Advanced Cancer Care Communication During the COVID-19 Pandemic.

Guided by communication accommodation theory, we studied 27 physician reports of patient-physician advanced cancer communication during the COVID-19 pandemic. Advanced cancer communication requires recognizing patients' psychosocial states and collaboratively engaging patients empathetically to develop the shared understanding necessary to guide decision-making. However, physicians found their communication underaccommodated, stemming from personal protection equipment, social distancing, and telemedicine.

Results of a Feasibility Pilot Pragmatic Trial Implementing Palliative Care in Skilled Nursing Facilities.

Seriously ill older adults are admitted for post-acute care in skilled nursing facilities (SNFs) for curative, rehabilitative treatments, yet experience high rates of re-hospitalization, and death. The primary palliative care in post-acute care (PPC-PAC) intervention is an evidence-based approach designed to help people with serious illness align treatment plans with goals of care, optimize quality of life, and improve satisfaction with their care. To conduct a preliminary study and evaluate the feasibility of implementing the PPC-PAC intervention in the post-acute care SNF setting.

Cercospora leaf spot impacts on postharvest disease and respiration of affected sugarbeet roots.

In Michigan, sugarbeets () are stored for up to 200 days post-harvest, during which sugar loss may occur due to energy use from respiration and factors like rot. Cercospora leaf spot (CLS) has been considered a potential predisposing factor for increased storage rot. To investigate these impacts, field and postharvest studies evaluated storage rot symptom development in sugarbeets with designated 'high' or 'low' in-season CLS severity.
