Feasibility of a healthcare system-based tetralogy of Fallot patient registry.

BACKGROUND: Patient-reported outcomes and epidemiological studies in adults with tetralogy of Fallot are lacking. Recruitment and longitudinal follow-up investigation across institutions is particularly challenging. Objectives of this study were to assess the feasibility of recruiting adult patients with tetralogy of Fallot for a patient-reported outcomes study, describe challenges for recruitment, and create an interactive, online tetralogy of Fallot registry. METHODS: Adult patients living with tetralogy of Fallot, aged 18-58 years, at the University of North Carolina were identified using diagnosis code query. A survey was designed to collect demographics, symptoms, history, and birth mother information. Recruitment was attempted by phone (Part I, n=20) or by email (Part II, n=20). Data analysis included thematic grouping of recruitment challenges and descriptive statistics. Feasibility threshold was 75% for recruitment and for data fields completed per patient. RESULTS: In Part I, 60% (12/20) were successfully contacted and eight (40%) were enrolled. Demographics and birth mother information were obtained for all enrolled patients. In Part II, 70% (14/20) were successfully contacted; 30% (6/20) enrolled and completed all data fields linked to REDCap database; the median time for survey completion was 8 minutes. Half of the patients had cardiac operations/procedures performed at more than one hospital. Automatic electronic data entry from the online survey was uncomplicated. CONCLUSIONS: Although recruitment (54%) fell below our feasibility threshold, enrolled individuals were willing to complete phone or online surveys. Incorrect contact information, privacy concerns, and patient-reported time constraints were challenges for recruitment. Creating an online survey and linked database is technically feasible and efficient for patient-reported outcomes research.

The Role of Immunotherapy in the Management of Esophageal Cancer in Patients Treated with Neoadjuvant Chemoradiation: An Analysis of the National Cancer Database.

BACKGROUND: The current National Comprehensive Cancer Network advises neoadjuvant chemoradiotherapy followed by surgery for locally advanced cases of esophageal cancer. The role of immunotherapy in this context is under heavy investigation. METHODS: Patients with esophageal adenocarcinoma were identified in the National Cancer Database (NCDB) from 2004 to 2019. Three groups were generated as follows: (a) no immunotherapy, (b) neoadjuvant immunotherapy, and (c) adjuvant immunotherapy. Overall survival was evaluated using the Kaplan-Meier method and Cox proportional hazard analysis, adjusting for previously described risk factors for mortality. RESULTS: Of the total 14,244 patients diagnosed with esophageal adenocarcinoma who received neoadjuvant chemoradiation, 14,065 patients did not receive immunotherapy, 110 received neoadjuvant immunotherapy, and 69 received adjuvant immunotherapy. When adjusting for established risk factors, adjuvant immunotherapy was associated with significantly improved survival compared to no immunotherapy and neoadjuvant immunotherapy during a median follow-up period of 35.2 months. No difference was noted among patients who received no immunotherapy vs. neoadjuvant immunotherapy in the same model. CONCLUSIONS: In this retrospective analysis of the NCDB, receiving adjuvant immunotherapy offered a significant survival advantage compared to no immunotherapy and neoadjuvant immunotherapy in the treatment of esophageal adenocarcinoma. The addition of neoadjuvant immunotherapy to patients treated with neoadjuvant chemoradiation did not improve survival in this cohort. Further studies are warranted to investigate the long-term outcomes of immunotherapy in esophageal cancer.

FlatWire Sternal Closure System technique for median sternotomy closure.

Sternal closure after median sternotomy traditionally uses a stainless steel wire cerclage. Sternal wires are placed through or around the sternum, and the wire ends are twisted together to bring the sternum back together. Complications of this technique include sternal instability, dehiscence, non-union, and increased pain. Compared to traditional wire cerclage, the Figure 8 FlatWire Sternal Closure System has been demonstrated to be stronger and significantly reduce sternal cut-through and postoperative pain. There was no significant difference in hospital length of stay or mean hospitalization cost. Operative time was slightly longer in the FlatWire group, but this difference has been attributed to the learning curve of mastering the FlatWire technique. This article and supplemental video will demonstrate the technique of FlatWire Sternal Closure System. Briefly, the FlatWire is placed around the sternum, and the FlatWire end is fed through the security box. Once all of the wires are placed, the Figure 8 tensioning device is used to tighten each wire through the security box to the appropriate tensile force. Next, the FlatWires are rotated 90 degrees to hold the sternal position temporarily. Once sternal approximation is achieved, each FlatWire is twisted 120 degrees, and any excess length of the FlatWire is clipped.

Bilateral Thoracoscopic Sympathectomy After Sternotomy for Left Ventricular Assist Device Insertion.

Our case is a 73-year-old male patient with persistent ventricular tachycardia leading to recent syncopal episodes despite ventricular tachycardia ablation and multiple stellate ganglion blocks, frequent hospital admissions, and acute on chronic congestive heart failure requiring an intraaortic balloon pump. The decision was made to proceed with left ventricular assist device placement and bilateral sympathectomies simultaneously. After performing the sternotomy and widely opening bilateral pleural spaces, the lower third of the stellate ganglia to the level of T4 was removed using a combination of the thoracoscope with the sternotomy incision. The use of thoracoscopy greatly assisted with visualization during the sympathectomy.

Enhanced recovery after thoracic surgery: Systematic review and meta-analysis.

ERATS decreased length of stay, postoperative complications, and readmission.

Thoracic Enhanced Recovery After Surgery: Single Academic Center Observations After Implementation.

BACKGROUND: Enhanced recovery after surgery (ERAS) is an evidence-based, multidisciplinary perioperative care model shown to reduce complications and hospital length of stay (LOS). While some thoracic ERAS studies were inconclusive, others demonstrated that ERAS improves patient outcomes after lung resections and provides more cost-effective care. We aimed to investigate the effects of preliminary implementation of an ERAS protocol, in comparison with conventional care, on lung resection outcomes at a single academic institution. METHODS: In this observational study, adult patients undergoing lung resections during the pre-ERAS (April 2014 to September 2015) and post-ERAS (January 2016 to May 2017) periods were identified. Relevant demographic, preoperative, anesthesia, and surgical variables were collected. Pre-ERAS and post-ERAS cohorts were compared in terms of hospital LOS, postoperative complications, and 30-day outcomes. RESULTS: We identified 264 patients, half in each cohort. Pre-ERAS and post-ERAS groups were similar with respect to age, race, and comorbidities. There were no significant differences in LOS, complications, 30-day readmission and mortality rates, or patient-reported outcomes. Of the patients with prolonged LOS, 31% had pulmonary complications, almost half of which were prolonged air leaks. ERAS adherence rate was approximately 60%. CONCLUSIONS: In the first year of implementation, median LOS, complications, and 30-day outcomes did not differ significantly between the pre-ERAS and post-ERAS groups. Prolonged air leaks commonly led to prolonged LOS; therefore, thoracic ERAS protocols could include interventions to reduce air leak and consideration for discharging patients with chest tubes placed to Heimlich valves. Buy-in and adherence to a new protocol are necessary for implementation to be effective.

Low Levels of Physical Activity Among Older Persons Living with HIV/AIDS Are Associated with Poor Physical Function.

Antiretroviral therapy (ART) has prolonged lives of persons living with HIV/AIDS (PLWHA), resulting in greater incidence of aging-related diseases and disability. Physical activity (PA) is recommended for healthy aging, but little is known about PA in older PLWHA. The purpose of this study was to objectively assess PA levels in older PLWHA and the associations with physical function. Twenty-one PLWHA, ≥50 years old, on ART with undetectable HIV-1 viral loads, wore an accelerometer to assess PA, including number of steps, activity intensity, and energy expenditure over 7 days. A physical function performance battery assessing aerobic capacity, strength, and gait speed was also completed. Average age was 66, and 67% were male. An average of 3,442 (interquartile range: 4,613) steps were walked daily, with 254.9 kcals expended. Participants spent most waking hours (75%) sedentary, with minimal hours (24%) in light-intensity activity. Only 5 min per day (35 min per week), on average, were spent in moderate-to-vigorous physical activity (MVPA). Maximal gait speed and 6-min walk test significantly correlated (p < .05) with all PA outcomes. Usual gait speed significantly correlated with all PA outcomes, except for daily kcals and light-intensity activity. Greater PA was associated with better physical performance, while high sedentary time was associated with poorer performance. To our knowledge, this is the first study to objectively measure PA in older PLWHA. Our findings indicate that older PLWHA accumulate substantial sedentary time. Most (86%) do not achieve recommended MVPA levels. This activity profile was associated with poor physical function. Providers should promote PA among PLWHA.

Diminished physical function in older HIV-infected adults in the Southeastern U.S. despite successful antiretroviral therapy.

BACKGROUND: As antiretroviral therapy efficacy improves, HIV is gradually being recognized more as a chronic disease within the aging HIV-infected population. While these individuals are surviving into old age, they may, however, be experiencing "accelerated aging" with greater declines in physical function than that observed among comparably matched individuals free of HIV. This decline is not well understood and it remains unclear if physical decline correlates with the degree of immunosuppression based on CD4 lymphocyte nadir. METHODS: In a cross-sectional study of accelerated aging in the older HIV-infected population on antiretroviral therapy (ART), physical performance evaluations were completed on a cohort of 107 HIV-infected subjects, age 50 years or older (with no HIV-1 RNA >200 copies/mL in the prior 12 months), and compared to reference ranges for age- and gender-matched HIV-uninfected persons. Physical performance testing consisted of four validated assessments: the 2.4-meter walk, 30-second chair stand, grip strength and 6-minute walk test. RESULTS: When compared to age- and gender-matched HIV-uninfected reference controls, older HIV-infected persons had diminished physical function. No correlation was found between physical function and degree of immunosuppression as determined by pre-ART CD4 nadir. CONCLUSIONS: Despite improved survival, HIV-infected adults on suppressive ART have diminished physical function compared to HIV-uninfected persons. The degree of HIV-associated immunosuppression does not correlate with the observed degree of physical function decline in older HIV-infected persons, suggesting the decline is mediated by other mechanisms.
