This technology may promote understanding of aortic root form and function, and facilitate valve-sparing surgery, and seems valuable for 3D exploration-and-measurement of cardiac anatomy in vivo.

Although surgical management is associated with improved outcomes, the optimal approach remains to be elucidated. We describe a case of AEF which was treated with a simultaneous repair of the atrium and esophagus via a right thoracotomy with an extra-pericardial off-pump approach.
Kommerell diverticulum (KD) is a dilated proximal aberrant subclavian artery associated with either right or left aortic arches (RAA-ARSA or LAA-ALSA). Although case series suggest KD may be a liability for vascular complications, the risk, pattern of dilation throughout the lifespan, and differences between arch sides, are not known.
A single-center retrospective review of patients of all ages with KD on cross-sectional imaging. Maximal short axis diameter of KD (KDmax), absolute and indexed to descending aortic (DAo) diameter, was correlated with age. Comparisons were made between arch sides. Patients with vascular complications are described.
One hundred and four patients with KD were included [68 (65%) RAA-ALSA, 36 (35%) LAA-ARSA; 43 (41%) asymptomatic]. Although KDmax was correlated with age (RAA-ALSA r=0.84 [p<.0001]; LAA-ARSA r=0.51 [p=0.001]), KDmax/DAo was not (RAA-ALSA r=0.14 [p=0.27]; LAA-ARSA r=-0.22 [p=0.21]). RAA-ALSA had larger KDmax/DAo (1.02±0.20 vs 0.89±0.18 mm/mm, p=0.002), more sy patients with LAA-ARSA and aneurysm risk factors. This suggests conservative management of asymptomatic KD is often reasonable, especially with RAA-ALSA.
Patients with congenitally corrected transposition of the great arteries (ccTGA) with intact ventricular septum (IVS) or d-looped transposition of the great arteries (DTGA) with IVS post atrial switch operation often develop left ventricular dysfunction after anatomical repair despite prior retraining of the morphologically left ventricle (mLV) using pulmonary artery banding (PAB). We examined histopathological changes in such mLV.
Capillary density, myocyte diameter, and interstitial fibrous area in the mLV were retrospectively evaluated in postmortem or explanted heart specimens obtained from patients with ccTGA/IVS or DTGA/IVS post atrial switch operation after PAB for retraining and compared with those of patients with normal cardiac anatomy, ccTGA/IVS or DTGA/IVS without PAB, and ccTGA or DTGA with high mLV pressure using generalized estimating equations models.
Adjusting for age, capillary density in four patients with ccTGA/IVS or DTGA/IVS after PAB was ∼20% lower than that in eight patients with normal cardiac anatomy (3149 ± 863 / um
vs 3978 ± 1206 /um
(mean, SD); p = 0.039), while myocyte diameter was ∼50% larger (16.2 ± 4.0 um vs 11.7 ± 2.4 um (mean, SD); p < 0.001). Interstitial fibrous area did not differ between the two groups (803 ± 422 um
vs 789 ± 480 um
, p = 0.92).
We observed significant cardiomyocyte hypertrophy but lower capillary density in patients with ccTGA/IVS or DTGA/IVS after PAB for retraining compared to normal controls. This suggests inadequate capillary growth is a potential pathological basis for mLV dysfunction occurring after retraining or anatomical repair.

The objective of this study is to examine the association between an academic medical center and free clinic referral partnership and subsequent hospital utilization and costs for uninsured patients discharged from the academic medical center's emergency department (ED) or inpatient hospital.
This retrospective, cross-sectional study included 6014 uninsured patients age 18 and older who were discharged from the academic medical center's ED or inpatient hospital between July 2016 and June 2017 and were followed for 90 days in the organization's electronic medical record to identify the occurrence and cost of subsequent same-hospital ED visits and hospital admissions. The occurrence of any subsequent ED visits or hospital admissions and the cost of subsequent hospital care were compared by free clinic referral status after inverse probability of treatment weighting.
Overall, 330 (5.5%) of uninsured patients were referred to the free clinic. Compared with patients referred to the free clinic, patients not referred had greater odds of any subsequent ED visits or hospital admissions within 90 days (odds ratio, 1.8; 95% confidence interval 1.7-2.0). https://www.selleckchem.com/products/zcl278.html For patients with any subsequent ED visits or hospital admissions, the mean cost of care for those who were not referred to the free clinic was 2.3 times higher (95% confidence interval 2.0-2.7) compared to referred patients.
An academic medical center-free clinic partnership for follow-up care after discharge from the ED or hospital admission is a promising approach for improving access to care for uninsured patients.

To date, there is no published local epidemiological evidence documenting the respiratory health effects of source specific air pollution in South Asia, where PM2.5 composition is different from past studies. Differences include more biomass and residue crop-burning emissions, which may have differing health implications.
We assessed PM2.5 associations with respiratory emergency department (ED) visits in a biomass-burning dominated high pollution region, and evaluated their variability by pollution source and composition.
Time-series regression modeling was applied to daily ED visits from January 2014 through December 2017. Air pollutant effect sizes were estimated after addressing long-term trends and seasonality, day-of-week, holidays, relative humidity, ambient temperature, and the effect modification by season, age, and sex.
PM2.5 yielded a significant association with increased respiratory ED visits [0.84% (95% CI 0.33%, 1.35%)] per 10 μg/m3 increase. The PM2.5 health effect size varied with season, the highest being during monsoon season, when fossil-fuel combustion sources dominated exposures.
