As healthcare continues its transition toward value-based care, it is increasingly important for transplant pharmacists to demonstrate their impact on patient care, health-related outcomes, and healthcare costs. Evidence-based quality and performance metrics are recognized as crucial tools for measuring the value of service. Yet, there is a lack of well-developed and agreed-upon specific metrics for many clinical pharmacy specialties, including solid organ transplantation.

This study interrogates the common assumption that parasocial grief, or grief for celebrities, is always less intense than grief for people in social relationships. An online 2 (Parasocial or Social) × 2 (Close or Distant) experiment with participants recruited on MTurk ( = 271) examined differences in people's anticipated grief responses after imagining the hypothetical death of either a celebrity or a person in their social network, who they considered to be either close or a more distant acquaintance. The results revealed that closeness, but unexpectedly not parasociality, affected people's imagined grief.

Although the influence of celebrities on public health-related attitudes and behaviors is well established, the specific role that celebrity examples play in shaping health-related social norm perceptions is not well understood. To examine the effect of celebrities on social norm perceptions, young adults were randomly assigned to read news articles about vaping that either featured one of four film stars using a vape pen or did not contain any celebrity exemplar. The presence or absence of a celebrity exemplar did not affect readers' perceptions of vaping social norms.

Article Synopsis
  • Some pancreatic cancers (about 8-10%) don't have a common mutation called KRAS, which makes them different from most cases.
  • In a study of 795 pancreatic cancer patients, 73 were found to have KRAS wild-type (normal) cancer, and many had other mutations that could be targeted for treatment.
  • The research shows that patients with this type of cancer are generally younger and may respond well to specific therapies, especially if they have certain genetic changes.

Background: Functional profiling of freshly isolated glioblastoma (GBM) cells is being evaluated as a next-generation method for precision oncology. While promising, its success largely depends on the method to evaluate treatment activity which requires sufficient resolution and specificity.

Methods: Here, we describe the 'precision oncology by single-cell profiling using ex vivo readouts of functionality' (PROSPERO) assay to evaluate the intrinsic susceptibility of high-grade brain tumor cells to respond to therapy.

The role of the transplant pharmacist is recognized by transplant programs, governmental groups, and professional organizations as an essential part of the transplant multidisciplinary team. This role has evolved drastically over the last decade with the advent of major advances in the science of transplantation and the growth of the field, which necessitate expanded pharmacy services to meet the needs of patients. Data now exist within all realms of the phases of care for a transplant recipient regarding the utility and benefit of a solid organ transplant (SOT) pharmacist.

Purpose: Anaplastic lymphoma kinase (ALK) aberrations have been identified in pediatric-type infant gliomas, but their occurrence across age groups, functional effects, and treatment response has not been broadly established.

Experimental Design: We performed a comprehensive analysis of ALK expression and genomic aberrations in both newly generated and retrospective data from 371 glioblastomas (156 adult, 205 infant/pediatric, and 10 congenital) with in vitro and in vivo validation of aberrations.

Results: ALK aberrations at the protein or genomic level were detected in 12% of gliomas (45/371) in a wide age range (0-80 years).

The clinical significance of gene fusions detected by DNA-based next generation sequencing remains unclear as resistance mechanisms to EGFR tyrosine kinase inhibitors in EGFR mutant non-small cell lung cancer. By studying EGFR inhibitor-resistant patients treated with a combination of an EGFR inhibitor and a drug targeting the putative resistance-causing fusion oncogene, we identify patients who benefit and those who do not from this treatment approach. Through evaluation including RNA-seq of potential drug resistance-imparting fusion oncogenes in 504 patients with EGFR mutant lung cancer, we identify only a minority of them as functional, potentially capable of imparting EGFR inhibitor resistance.

Belatacept has demonstrated effectiveness for preventing rejection in kidney transplant and has a favorable side effect profile. Studies assessing long-term infectious complications with belatacept compared to tacrolimus are limited. The purpose of this program evaluation was to determine the proportion of patients who developed an infection when converted to belatacept compared to those on tacrolimus.

Objectives: Beers Criteria and the Screening Tool of Older Persons' Prescriptions (STOPP) Criteria/Screening Tool to Alert to Right Treatment Criteria are used to assess potentially inappropriate prescribing and medications, which could pose a harm to those of older age. The purpose of this study was to assess and compare the use of Beers and STOPP Criteria in older kidney transplant recipients.

Methods: This was a dual-center, retrospective chart review from May 1, 2014, to March 1, 2018, including kidney transplant recipients 65 years and older.

The health and economic burden of diabetes mellitus across the United States and the world is such that effective care is crucial to improving outcomes, including macro and microvascular complications, and lowering health care costs. Pharmacists are well placed within communities to provide the critical care necessary for patients with diabetes and have a unique skillset that has demonstrated clear benefits in clinical and non-clinical outcomes. Here, we will provide a narrative review of the literature including the role of the pharmacist in different care models, outcomes associated with pharmacist care, and future directions and opportunities for pharmacist-managed diabetes.

Background: Solid organ transplant recipients (SOTRs) are at disproportionate risk for severe Coronavirus Disease 2019 (COVID-19). Vaccination is a key preventative strategy but is associated with decreased humoral responses among SOTR. Whether dampened immune responses correlate with reduced clinical effectiveness is unclear.

The SARS-CoV-2 pandemic continues to place a substantial burden on healthcare systems. Outpatient therapies for mild-to-moderate disease have reduced hospitalizations and deaths in clinical trials, but the real-world effectiveness of monoclonal antibodies and oral antiviral agents in solid organ transplant recipients (SOTR) with coronavirus disease-2019 (COVID-19) is largely uncharacterized. We conducted a single-center, retrospective review of 122 SOTR diagnosed with COVID-19 in the outpatient setting during the Omicron surge to address this knowledge gap.

Prognostically relevant RNA expression states exist in pancreatic ductal adenocarcinoma (PDAC), but our understanding of their drivers, stability, and relationship to therapeutic response is limited. To examine these attributes systematically, we profiled metastatic biopsies and matched organoid models at single-cell resolution. In vivo, we identify a new intermediate PDAC transcriptional cell state and uncover distinct site- and state-specific tumor microenvironments (TMEs).

germline mutations are associated with an increased risk of breast and ovarian cancer. Recent findings of others suggest that mutation carriers also bear an increased risk of esophageal and gastric cancer. Here, we employ a mouse model to show that unresolved replication stress (RS) in heterozygous cells drives esophageal tumorigenesis in a model of the human equivalent.
