Disease-modifying therapies for amyloid transthyretin cardiomyopathy: Current and emerging medications.

Transthyretin amyloidosis (ATTR) is a rare disease that results in amyloid fibril misfolding and deposition in multiple organs, including the heart, leading to the development of ATTR cardiomyopathy (ATTR-CM), which is associated with poor outcomes. In the last decade, several disease-modifying medications are in advanced stages of clinical development or have been approved to treat ATTR-CM. The purpose of this review is to critically evaluate clinical trial data investigating the use of approved and investigational medications for the treatment of ATTR-CM.

Pathologic complete response in patients with esophageal cancer receiving neoadjuvant chemotherapy or chemoradiation: A systematic review and meta-analysis.

Background: Neoadjuvant chemoradiation and chemotherapy are recommended for the treatment of nonmetastatic esophageal cancer. The benefit of neoadjuvant treatment is mostly limited to patients who exhibit pathologic complete response (pCR). Existing estimates of pCR rates among patients receiving neoadjuvant therapy have not been synthesized and lack precision.

Investigation of genomic and transcriptomic risk factors in clopidogrel response in African Americans.

Clopidogrel, an anti-platelet drug, used to prevent thrombosis after percutaneous coronary intervention. Clopidogrel resistance results in recurring ischemic episodes, with African Americans suffering disproportionately. The aim of this study was to identify biomarkers of clopidogrel resistance in African American patients.

Cost-effectiveness of systematic screening and treatment of transthyretin amyloid cardiomyopathy (ATTR-CM) in patients with heart failure with preserved ejection fraction (HFpEF) in United States.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed cause of heart failure in clinical practice. Tc-pyrophosphate scintigraphy (PYP-scan) improves the accuracy of ATTR-CM detection, enabling timely initiation of tafamidis, a drug that slows the progression of ATTR-CM and lowers the risk of adverse cardiac events. PYP-scans, serum free light-chain (FLC) test and immunofixation electrophoresis (IFE) are critical components of a systematic screening.

Racial and Ethnic Inequities in US Oncology Clinical Trial Participation From 2017 to 2022.

Importance: There is increasing recognition from regulatory agencies that racial and ethnic representation in clinical trials is inadequate and linked to health inequities. The extent of racial inequities in clinical trial participation is unclear because prior studies have synthesized enrollment data from published trials, which often do not report participant race and ethnicity.

Objective: To evaluate racial and ethnic inequities in oncology clinical trial participation in a contemporary cohort of patients with cancer before and during the COVID-19 pandemic.

Assessing the Contribution of Scanned Outside Documents to the Completeness of Real-World Data Abstraction.

Purpose: Electronic health record (EHR) data are widely used in precision medicine, quality improvement, disease surveillance, and population health management. However, a significant amount of EHR data are stored in unstructured formats including scanned documents external to the treatment facility presenting an informatics challenge for secondary use. Studies are needed to characterize the clinical information uniquely available in scanned outside documents (SODs) to understand to what extent the availability of such information affects the use of these real-world data for cancer research.

Prompt initiation of triple therapy following hospitalization for a chronic obstructive pulmonary disease exacerbation in the United States: An analysis of the PRIMUS study.

Severe exacerbations requiring hospitalization contribute a substantial portion of the morbidity and costs of chronic obstructive pulmonary disease (COPD). Triple therapy (inhaled corticosteroid + long-acting β-agonist + long-acting muscarinic antagonist) is a recommended option for patients who experience recurrent COPD exacerbations or persistent symptoms. Few real-world studies have specifically examined the effect of prompt initiation of triple therapy, specifically among patients hospitalized for a COPD exacerbation.

Thromboembolic Events in Users of Warfarin Treated with Different Skeletal Muscle Relaxants.

Background and Objectives: Warfarin and a skeletal muscle relaxant are co-treatments in nearly a quarter-million annual United States (US) office visits. Despite international calls to minimize patient harm arising from anticoagulant drug interactions, scant data exist on clinical outcomes in real-world populations. We examined effects of concomitant use of warfarin and individual muscle relaxants on rates of hospitalization for thromboembolism among economically disadvantaged persons.

Apixaban Concentrations in Routine Clinical Care of Older Adults With Nonvalvular Atrial Fibrillation.

Background: Direct-acting oral anticoagulants are first-line agents for prevention of stroke in patients with nonvalvular atrial fibrillation (NVAF), but data are limited for the oldest patients, and with reduced dosing.

Objectives: To determine steady-state apixaban peak and trough concentrations during routine care of older adults with NVAF, compare concentrations to clinical trial concentrations, and explore factors associated with concentrations.

Methods: A cross-sectional study of medically stable older adults with NVAF (≥75 years or ≥70 years if Black) receiving apixaban.

Impact of socioeconomic status and rurality on cancer-specific survival among women with de novo metastatic breast cancer by race/ethnicity.

Purpose: There are approximately 150,000 women living with metastatic breast cancer (mBC) in the United States. Disparities in de novo mBC incidence and mortality exist across race/ethnicity, socioeconomic status (SES), and rurality. However, how SES and rurality independently impact mBC outcomes across different racial/ethnic groups is not fully understood.

Impact of time to distant recurrence on breast cancer-specific mortality in hormone receptor-positive breast cancer.

Women with hormone receptor (HR)-positive early-stage breast cancer (BC) have five-year survival rates of > 90% but remain at serious risk for developing distant metastases beyond five years from diagnosis. This retrospective cohort study used data from the Surveillance, Epidemiology, and End Results (SEER) registries to examine associations between distant recurrence-free interval (DRFI) and risk of BC-specific mortality following distant relapse. The analysis includes 1,057 women with second primary stage IV BC who were initially diagnosed with AJCC stages I-III HR-positive BC between1990 and 2016.

PRIMUS - Prompt Initiation of Maintenance Therapy in the US: A Real-World Analysis of Clinical and Economic Outcomes Among Patients Initiating Triple Therapy Following a COPD Exacerbation.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) may experience moderate (requiring outpatient care) or severe (requiring hospitalization) disease exacerbations. Guidelines recommend escalation from dual to triple therapy (inhaled corticosteroid + long-acting beta agonist + long-acting muscarinic antagonist) after two moderate or one severe exacerbation in a year. This study examined whether prompt initiation of triple therapy lowers risk of future exacerbations and reduces healthcare costs, compared to delayed/very delayed triple therapy after an exacerbation.

Applicability of Pharmacogenomically Guided Medication Treatment during Hospitalization of At-Risk Minority Patients.

Known disparities exist in the availability of pharmacogenomic information for minority populations, amplifying uncertainty around clinical utility for these groups. We conducted a multi-site inpatient pharmacogenomic implementation program among self-identified African-Americans (AA; = 135) with numerous rehospitalizations ( = 341) from 2017 to 2020 (NIH-funded ACCOuNT project/clinicaltrials.gov#NCT03225820).

The association between physical health-related quality of life, physical functioning, and risk of contralateral breast cancer among older women.

Background: Physical limitations prior to cancer diagnosis may lead to suboptimal health outcomes. Our objective was to evaluate the impacts of poor physical health-related quality of life (HRQOL) and physical functioning (PF) on the risk of contralateral breast cancer (CBC).

Methods: We performed a nested case-control study of women with invasive unilateral breast cancer (UBC) who did not receive prophylactic contralateral mastectomy using the Surveillance, Epidemiology and End Results Medicare Health Outcomes Survey data resource.

Clinical predictors of poor outcomes in patients with sickle cell disease and COVID-19 infection.

We aimed to identify predictors of outcomes and survival in patients living in 4 major metropolitan areas who had sickle cell disease (SCD) and COVID-19 to inform best approaches to prevention and care. Data were collected at baseline and during the clinical course in SCD patients diagnosed with COVID-19 in four COVID-19 epicenters. Patients were followed up posthospital discharge for up to 3 months.
