Cytomegalovirus (CMV) infection is related to acute rejection and graft loss after kidney transplantation, though the underlying mechanism remains largely unknown. Some CMV strains produce a peptide that is identical to a peptide sequence found in the leader peptide of specific HLA-A and -C alleles. In this retrospective study of 351 kidney transplantations, we explored whether CMV-seropositive recipients without the VMAPRTLIL, VMAPRTLLL or VMAPRTLVL HLA class I leader peptide receiving a transplant from a donor with this peptide, faced an increased risk of T-cell-mediated rejection (TCMR) in the first 90 days after transplantation.

Despite the rapid growth in the number of scientific publications, our understanding of author publication trajectories remains limited. Here we propose an embedding-based framework for tracking author trajectories in a geometric space that leverages the information encoded in the publication sequences, namely the list of the consecutive publication venues for each scholar. Using the publication histories of approximately 30,000 social media researchers, we obtain a knowledge space that broadly captures essential information about periodicals as well as complex (inter-)disciplinary structures of science.

Objectives: To explore the barriers to and facilitators of caregiving experienced by family caregivers of patients with COVID-19 who had been in intensive care in the pandemic's earliest months.
Methods: In-depth qualitative interviews were conducted by web conference with 16 adults recovering at home after intubation for COVID-19 in an intensive care unit at a major academic medical center and their primary caregivers from March to August 2020 (N = 32).
Purpose: Oral anti-cancer agents (OAAs) represent a new frontier in cancer treatment, but we do not know how well patients incorporate the strategies that they are taught for managing the side effects of OAAs into their daily lives. The purpose of this study was to understand how OAA side effects influenced patients' lives and what strategies patients used to manage them.
Methods: The study used an interpretive descriptive design utilizing photo elicitation interviews (PEI).
Background: While adverse events and toxicities related to cancer drug therapy in the ambulatory oncology setting are common and often rooted in communication challenges, few studies have examined the problems of communication or tested tools to improve communication in this unique, high-risk setting.
Objective: To determine the feasibility and acceptability of a virtual interdisciplinary communication Workshop designed to strengthen communication across ambulatory oncology teams members.
Methods: Surveys of patients and clinicians in one ambulatory oncology clinic were analyzed and informed the communication intervention: an interdisciplinary virtual Workshop.
Background: In the United States, hematopoietic stem cell transplant (HCT) surpasses 22,000 procedures annually. Due to the demanding and time-intensive process of an HCT, patients and family care partners face unique challenges involving their health and well-being. Positive psychology interventions (PPIs) may offer potential solutions to help boost health and well-being.

Objective: To compare machine learning recommender (ML recommender) computer tailoring of motivational text messages vs a standard motivational text-based intervention (standard messaging) and a viral peer-recruitment tool kit (viral tool kit) for recruiting friends and family vs no tool kit in a smoking-cessation intervention.
Design, Setting, And Participants: This 2 ×2 factorial randomized clinical trial with partial allocation, conducted between July 2017 and September 2019 within an online tobacco intervention, recruited current smokers aged 18 years and older who spoke English from the US via the internet and peer referral.
Background: Family caregivers often experience psychological distress during a critical care hospitalization, potentially compromising their ability to function effectively in a supportive role. A better understanding of the sources of family caregiver distress is needed to inform strategies to mitigate its development and impact.
Objective: To explore sources of family caregiver psychological distress during a critical care hospitalization and how caregivers' experiences may differ by their anxiety level.
Aim And Objective: To identify how family caregivers adapt to the caregiving role following a relative's COVID-19-related intensive care unit (ICU) hospitalisation.
Background: Family caregiving is often associated with poor health amongst caregivers which may limit their capacity to effectively support patients. Though severe COVID-19 infection has necessitated increasing numbers of persons who require caregiver support, little is known about these caregivers, the persons they are caring for, or the strategies used to effectively adjust to the caregiving role.
