RESUMO

OBJECTIVE: The objective of this study was to obtain the perception of patients on the use of portable digital media devices by providers during patient care and compare the findings to a previous study that examined providers' perceptions on the use of these devices. DESIGN: This was a cross-sectional survey study. SETTING: This study took place at a large tertiary referral center. PARTICIPANTS: Participants were identified via inpatient lists from general surgery services. RESULTS: Of those eligible to participate, 70% completed the questionnaire. While some situations were seen as less appropriate, the overall consensus from participants was that informing the patient of why the physician is using a digital media device made it more appropriate. CONCLUSION: Patients recognize digital device use in healthcare is appropriate and professional when discussed with them in advance. Overall, patients and providers are in agreement that portable digital technology can improve patient care and open communication about the use improves the provider-patient relationship. There is some risk to patient trust in using digital devices in their presence.

RESUMO

OBJECTIVE: Congenitally corrected transposition of the great arteries (ccTGA) encompasses a diverse morphologic cohort, for which multiple treatment pathways exist. Understanding surgical outcomes among various pathways and their determinants are challenged by limited sample size and follow-up, and heterogeneity. We sought to investigate these questions with a large cohort of ccTGA patients presenting at different ages and representing the full therapeutic spectrum. METHODS: Retrospective review of 240 patients diagnosed with ccTGA from Cleveland Clinic coupled with prospective cross-sectional follow-up. Forty-six patients whose definitive procedure was completed elsewhere were excluded. Time-related survival was described among treatment pathways using actuarial, time-varying covariate, and competing risks analyses. Temporal trends in longitudinal valve and ventricular function were assessed using nonlinear mixed-effects models. RESULTS: Median follow-up was 10 years. Seventy-nine patients with ccTGA underwent anatomic repair, 45 physiologic repair, 24 Fontan palliation, and 6 primary transplant. Forty patients managed expectantly had excellent long-term survival when considered from time of presentation, but benefited from failures captured following transition to physiologic repair or transplant. Morphologic right ventricular dysfunction after physiologic repair increased from 68% to 85% after 5 years, whereas morphologic left ventricular function was stable in anatomic repair, especially with early surgery. Transplant-free survival at 15 years for anatomic and physiologic repair was 80% and 71%, respectively. CONCLUSIONS: Early anatomic repair may be preferable to physiologic repair for select ccTGA patients. Late attrition after physiologic repair represents failure of expectant management and progressive tricuspid valve and morphologic right ventricular dysfunction compared with anatomic repair, where morphologic left ventricular function is relatively preserved.

RESUMO

Cardiac progenitor cells (CPCs) have been shown to promote cardiac regeneration and improve heart function. However, evidence suggests that their regenerative capacity may be limited in conditions of severe hypoxia. Elucidating the mechanisms involved in CPC protection against hypoxic stress is essential to maximize their cardioprotective and therapeutic potential. We investigated the effects of hypoxic stress on CPCs and found significant reduction in proliferation and impairment of vasculogenesis, which were associated with induction of quiescence, as indicated by accumulation of cells in the G0-phase of the cell cycle and growth recovery when cells were returned to normoxia. Induction of quiescence was associated with a decrease in the expression of c-Myc through mechanisms involving protein degradation and upregulation of p21. Inhibition of c-Myc mimicked the effects of severe hypoxia on CPC proliferation, also triggering quiescence. Surprisingly, these effects did not involve changes in p21 expression, indicating that other hypoxia-activated factors may induce p21 in CPCs. Our results suggest that hypoxic stress compromises CPC function by inducing quiescence in part through downregulation of c-Myc. In addition, we found that c-Myc is required to preserve CPC growth, suggesting that modulation of pathways downstream of it may re-activate CPC regenerative potential under ischemic conditions.
