Abstract
Importance Following treatment, breast cancer survivors face challenges participating in valued activities. Objective To determine whether a telephone-based coaching rehabilitation intervention enhances activity participation in the year following breast cancer treatment. Design, Setting, and Participants In this multisite, single-blind randomized clinical trial (Optimizing Functional Recovery of Breast Cancer Survivors), recruitment occurred between August 28, 2019, and April 30, 2022. Data collection was completed by April 1, 2023. Participants were recruited from 2 cancer centers (Dartmouth College and the University of Alabama at Birmingham) and via social media advertisements. Women aged 18 years or older who had completed primary treatment for stage I to III breast cancer within 1 year and reported participation restrictions were eligible to participate. Randomization was stratified by site, treatment, and time since treatment. Interventions The intervention, delivered via telephone over 9 sessions, used behavioral activation and problem-solving principles to promote activity participation. The education-based attention control condition was delivered via telephone at matched intervals. Main Outcomes and Measures The primary outcome was participation, assessed using 5 measures, including Patient-Reported Outcomes Measurement Information System (PROMIS) social participation-satisfaction measure. One individualized outcome allowed participants to specify activities for which they wanted to foster recovery. Outcomes were collected by telephone by blinded coordinators at baseline and at 8, 20, and 44 weeks. The individualized outcome was assessed at the first and last intervention and control session. Results Among 1996 patients identified, 303 were eligible and enrolled. Of these, 284 women (94%; mean [SD] age, 56.1 [10.2] years) completed baseline assessments and were randomized, and 81% or more of each group completed the final assessment with no adverse events. Of those who completed the final assessment, 118 of 114 (82%) were in the intervention group, and 113 of 140 (81%) were attention control participants. Between-group differences were not statistically significant for the main measures of PROMIS satisfaction (week 20: Cohen d, 0.1 [95% CI, -0.09 to 0.29] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]) and ability (week 20: Cohen d, 0.15 [95% CI, -0.06 to 0.37] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]). On the individualized outcome, intervention participants reported significantly greater improvements in activity satisfaction (Cohen d, 0.76 [95% CI, 0.48-1.02]) and performance (Cohen d, 0.60 [95% CI, 0.32-0.87]). Conclusions and Relevance In this randomized clinical trial, the intervention catalyzed greater improvements in self-selected activity participation and goal disengagement but did not otherwise accelerate recovery compared with the control condition. Future research should determine what intervention features may lead to the greatest reductions in participation restrictions and other measures that may detect functional recovery. Trial Registration ClinicalTrials.gov Identifier: NCT03915548.

Abstract
Barth syndrome is an X-linked disorder characterized by dilated cardiomyopathy, cyclic neutropenia, skeletal myopathy, abnormal mitochondria, and growth deficiency. The primary defect is a mutation in the TAZ gene on the X chromosome at Xq28, resulting in abnormal phospholipid biosynthesis and cardiolipin deficiency. To date, there has been no systematic evaluation of the cardiac phenotype. We report five cases of cardiac arrest and/or placement of an internal cardiac defibrillator with documented ventricular arrhythmia. We suggest that ventricular arrhythmia is part of the primary phenotype of the disorder and that patients should be screened accordingly.

Abstract
The murine homeobox gene Csx/Nkx2.5 is an evolutionarily highly conserved gene related to the Drosophila tinman gene, which specifies cardiac and visceral mesoderm. Since Csx/Nkx2.5 plays an essential role in heart development, studying its regulation is essential for the better understanding of molecular mechanisms of cardiogenesis and the pathogenesis of congenital heart disease in humans. In this study, we characterized the murine Csx/Nkx2.5 gene and identified two novel untranslated exons, 1a, and 1b, resulting in three different Csx/Nkx2.5 transcripts. To examine the tissue-specific transcriptional regulation in vivo, we analyzed a total of 23 kb of Csx/Nkx2.5 upstream and downstream sequences by generating transgenic embryos carrying lacZ reporter constructs containing various lengths of flanking sequence. With 14 kb of 5′ flanking sequence, lacZ expression was observed in the cardiac crescent at E7.5, and in the outflow tract, the interatrial groove, the atrioventricular canal and right and left ventricles, as well as in pharyngeal floor, thyroid primordia, and stomach at E10.5. In adult animals, lacZ expression of the transgene was limited to the atrioventricular junction and the subendocardium of the ventricular septum. Reducing the size of flanking sequence to 3.3 kb of intron 2 restricted lacZ expression to the outflow tract and the basal part of the right ventricle in E10.5 embryos. In contrast, the addition of 6 kb of 3′ flanking sequence caused strong expression of the reporter gene in the entire right ventricle. Interestingly, Csx/Nkx2. 5 seems to be negatively regulated by its own gene product, because when lacZ was “knocked-in” to replace the entire coding exons, lacZ expression was much higher in the heart of homozygous embryos than that in the heterozygote. These results indicate that the transcriptional regulatory elements of Csx/Nkx 2.5 seems unexpectedly highly modular, and is temporally regulated in a dynamic manner by different enhancer regions. Since Csx/Nkx2.5-like genes are expressed in all species having a heart, their complex modular organization with multiple enhancers probably reflects progressive addition of regulatory elements during the evolution from a simple heart tube to a complex four-chambered organ.

Abstract
BACKGROUND Csx/Nkx2.5, a murine nonclustered homeobox gene expressed primarily in the heart, has significant sequence similarity to the Drosophila tinman gene. Tinman is essential for heart and gut formation in Drosophila. Targeted mutation in the mouse gene, Csx/Nkx2.5, arrests cardiac development during early embryonic stages, suggesting an evolutionary conservation in cardiogenesis. MATERIALS AND METHODS We have isolated and characterized a human homolog, hCsx, from an adult cardiac cDNA library. Northern blotting and ribonuclease protection was used to define the pattern of expression during normal development and in disease states. Chromosomal localization of the gene was determined by somatic cell hybrid analysis and fluorescent in situ hybridization. RESULTS The predicted amino acid sequence of hCsx has 87% overall homology to the murine gene with 100% identity in the homeodomain. The homeodomain sequence of hCsx is 95% identical to its Xenopus homolog, and 65% to tinman. hCsx mRNA was detected exclusively in the heart. hCsx transcript was detected at 12 weeks in human embryonic heart, the earliest time point examined, and was up-regulated 5-fold between 12 and 19 weeks. There was no significant alteration of hCsx message level in the myocardium of 14 patients with end stage heart failure compared to a normal control. The human gene mapped to the distal portion of chromosome 5, the 5q34-q35 region. This defines a new synteny region between human chromosome 5q and the t-locus of mouse chromosome 17, where the mouse Csx gene is located. CONCLUSIONS hCsx, the human homolog of Drosophila tinman, is expressed in heart in a tissue restricted manner. Distal 5q trisomies produce several phenotypic abnormalities, including a high incidence of congenital heart disease. Isolation of the hCsx gene will allow further studies of mutations in this gene and their potential associations with some forms of congenital heart disease in humans.
