A Patient-Centered Conceptual Model of AYA Cancer Survivorship Care Informed by a Qualitative Interview Study.

: Conceptual models provide frameworks to illustrate relationships among patient-, provider-, system-, and community-level factors that inform care delivery and research. Existing models of cancer survivorship care focus largely on pediatric or adult populations whose needs differ from adolescents and young adults (AYAs). We developed a patient-centered conceptual model of AYA survivorship care.

Reducing Central Nervous System-Active Medications to Prevent Falls and Injuries Among Older Adults: A Cluster Randomized Clinical Trial.

Importance: High-risk medications that contribute to adverse health outcomes are frequently prescribed to older adults. Deprescribing interventions reduce their use, but studies are often not designed to examine effects on patient-relevant health outcomes.

Objective: To test the effect of a health system-embedded deprescribing intervention targeting older adults and their primary care clinicians for reducing the use of central nervous system-active drugs and preventing medically treated falls.

A health-system-embedded deprescribing intervention targeting patients and providers to prevent falls in older adults (STOP-FALLS trial): study protocol for a pragmatic cluster-randomized controlled trial.

Background: Central nervous system (CNS) active medications have been consistently linked to falls in older people. However, few randomized trials have evaluated whether CNS-active medication reduction reduces falls and fall-related injuries. The objective of the Reducing CNS-active Medications to Prevent Falls and Injuries in Older Adults (STOP-FALLS) trial is to test the effectiveness of a health-system-embedded deprescribing intervention focused on CNS-active medications on the incidence of medically treated falls among community-dwelling older adults.

STRategies to Improve Pain and Enjoy life (STRIPE): Protocol for a pragmatic randomized trial of pain coping skills training and opioid medication taper guidance for patients on long-term opioid therapy.

High-dose, long-term opioid therapy (LtOT) is associated with risk for serious harms. Rapid opioid discontinuation may lead to increased pain, psychological distress, and illicit opioid use, but gradual, supported opioid taper may reduce these risks. We previously demonstrated that an opioid taper support and pain coping skills training intervention reduced opioid dose more than usual care (43% vs 19% dose reduction from baseline), with no increase in pain intensity and a significant reduction in activity interference.

Changes in use of opioid therapy after colon cancer diagnosis: a population-based study.

Purpose: To describe patterns of opioid use in cancer survivors.

Methods: In a cohort study of colon cancer patients diagnosed during 1995-2014 and enrolled at two Kaiser Permanente regions, we constructed quarterly measures of opioid use from 1 year before cancer diagnosis through 5 years after diagnosis to examine changes in use. Measures included any use, incident use, regular use (use ≥ 45 days in a 91-day quarter), and average daily dose (converted to morphine milligram equivalent, MME).

Use of antidepressants after colon cancer diagnosis and risk of recurrence.

Objective: Prior research examining the association between use of antidepressants after colon cancer diagnosis and risk of recurrence is scant. We evaluated this association among colon cancer patients diagnosed at two integrated health care delivery systems in the United States.

Methods: We conducted a cohort study of stage I to IIIA colon cancer patients diagnosed at greater than or equal to 18 years of age at Kaiser Permanente Colorado and Kaiser Permanente Washington during 1995 to 2014.

Risk of colon cancer recurrence in relation to diabetes.

Purpose: To describe the association between diabetes and colon cancer recurrence.

Methods: We conducted a cohort study at two integrated health care delivery systems in the United States. Using tumor registry data, we identified patients aged ≥ 18 years when diagnosed with stage I-IIIA adenocarcinomas of the colon during 1995-2014.

Glad you asked: participants' opinions of re-consent for dbGap data submission.

No consensus exists about when researchers need additional participant consent (reconsent) to submit existing data to the federal database of Genotypes and Phenotypes (dbGaP). Re-consent for submission of their data to dbGaP was sought from 1,340 study participants, 1,159 (86%) of whom agreed. We invited the first 400 of those who agreed to complete a telephone survey about their reasoning for their consent decision and their satisfaction with the reconsent process; 365 participants completed the survey.

E2A acts in cis in G1 phase of cell cycle to promote Ig gene diversification.

Rearranged Ig genes undergo diversification in sequence and structure initiated by the DNA deaminase, activation-induced deaminase. Ig genes must be transcribed for diversification to occur, but whether there are additional requirements for cis activation has not been established. Here we show, by chromatin immunoprecipitation, that the regulatory factor E2A associates with the rearranged Ig lambda(R) gene in the chicken DT40 B cell line, which performs constitutive Ig gene diversification.

The MRE11-RAD50-NBS1 complex accelerates somatic hypermutation and gene conversion of immunoglobulin variable regions.

Targeted diversification of immunoglobulin variable regions is induced by activation-induced deaminase and may occur by either somatic hypermutation or gene conversion. MRE11-RAD50-NBS1 (MRN) is a ubiquitous and conserved nuclease complex critical for DNA break repair and is essential in class-switch recombination. Here we show that ectopic expression of NBS1, the regulatory subunit of MRN, accelerated hypermutation in the human B cell line Ramos and accelerated gene conversion in the chicken B cell line DT40.
