The Mutographs Cancer Grand Challenge team aimed to discover unknown causes of cancer through mutational epidemiology, an alliance of cancer epidemiology and somatic genomics. By generating whole-genome sequences from thousands of cancers and normal tissues from more than 30 countries on five continents, it discovered unsuspected mutagenic exposures affecting millions of people, raised the possibility that some carcinogens act by altering forces of selection in tissue microenvironments rather than by mutagenesis, and demonstrated changes to the direction of somatic evolution in normal cells of the human body in response to exogenous exposures and noncancer diseases.

Background: The Centers for Medicare and Medicaid Services (CMS) Star Ratings program incentivizes health plans in Medicare to improve performance on a variety of quality measures such as adherence to renin-angiotensin system antagonists (RASAs). Adherence to RASA medications, defined as having a proportion of days covered (PDC) of at least 80%, has been improving for several years, suggesting that further investigation is needed to assess the appropriateness of the current 80% PDC threshold for medication adherence as an indicator of quality. The 80% PDC threshold has been found to be associated with improved health care resource utilization outcomes; however, little evidence exists to show that this threshold is optimal.

Introduction: Novel approaches to improve long-term outcomes in kidney transplant recipients are required. Here, we present the 5-year data from a multicenter, prospective, Phase 3b trial evaluating treatment outcomes with standard (STD) or low (LOW) dose prolonged-release tacrolimus (TAC) combined with ACEi/ARB or other antihypertensive therapy (OAHT) in Canadian kidney transplant recipients.

Methods: Adult de novo kidney transplant recipients were randomized 2 × 2 to STD or LOW dose TAC and ACEi/ARB or OAHT.

Purpose: This study explored the experiences of rural caregivers who require temporary housing during hospital treatment when healthcare is not available in their home communities. Understanding these experiences can identify challenges and inform solutions for improving rural access to healthcare.

Methods: We conducted a community-engaged qualitative study using semi-structured interviews with caregivers who stayed at a healthcare hospitality house in Charlotte, NC.

Background: Certain demographics and/or risk factors contribute to complications following cervical spinal surgery including pseudarthrosis, prolonged pain, and reduced quality of life (QoL). Pulsed electromagnetic field (PEMF) stimulation is a non-invasive therapy that may enhance fusion success in at-risk patients.

Objective: To evaluate the safety and efficacy of post-operative adjunctive PEMF therapy following cervical spinal surgery in subjects at risk for pseudarthrosis.
