Exposure to neonatal hyperoxia reduced body weight; survival rate; and expressions of von Willebrand factor, HIF-1α, phosphor mammalian target of rapamycin, VEGF, and endothelial nitric oxide synthase and increased the mean linear intercept values in the pups. Roxadustat administration reversed these effects.
Hyperoxia suppressed pulmonary vascular development and the expression of proangiogenic factors. Roxadustat promoted pulmonary angiogenesis on hyperoxia exposure by stabilizing HIF-1α and upregulating the expression of proangiogenic factors, indicating its potential in clinical and therapeutic applications.

Hyperuricemia has been increasingly prevalent and linked to future cardio-metabolic risks in adolescent population. The study aims to explore the relationship between anthropometric indices and hyperuricemia among adolescent athletes.
This was a cross-sectional study of 387 student athletes (218 males and 169 females; mean age, 17.4 ± 1.3 years) in Northern Taiwan in 2013-2015. We exhibited the prevalence of hyperuricemia among this population, and tested the association of serum uric acid levels with different anthropometric parameters in males and females respectively.
A total of 59 (27.1%) male and 37 (21.8%) female adolescent athletes had hyperuricemia. Both in male and female adolescents, several obesity-related anthropometric parameters were significantly higher in hyperuricemia groups than in non-hyperuricemia groups. The odds of having hyperuricemia significantly increased with increasing BMI, BMI z-score, waist circumference and waist-to-height ratio in logistic regression analysis. There was a U-shaped association between uric acid level and body fat percentage (BF%) in both genders. Subjects whose BF% in lowest-body-fat-percentage quintile (quintile 1) and highest-body-fat-percentage quintile (quintile 5) had higher mean serum uric acid level than subjects whose BF% in the middle three quintiles. In both genders, the odds ratio (OR) of having hyperuricemia in subjects whose BF% in quintile 1 remained significantly higher than the OR in the middle three quintiles (the reference) after adjusting for age and BMI z-score.
In addition to the positive association between obesity and hyperuricemia, there is a U shape association between BF% and prevalence of hyperuricemia among adolescent athletes of both genders.

Distinguishing coronavirus disease 2019 (COVID-19) pneumonia from other lung diseases is often difficult, especially in a highly comorbid patient population in a low prevalence region. We aimed to distinguish clinical data and computed tomography (CT) images between COVID-19 and other lung diseases in an advanced care hospital.
We assessed clinical characteristics, laboratory data, and chest CT images of patients with COVID-19 and non-COVID-19 patients who were suspected of having COVID-19 between February 20 and May 21, 2020, at the University of Tokyo Hospital.
Typical appearance for COVID-19 on CT images were found in 24 of 29 COVID-19 cases and 21 of 168 non-COVID-19 cases, according to the Radiological Society of North America Expert Consensus Statement (for predicting COVID-19, sensitivity 0.828, specificity 0.875, positive predictive value 0.533, negative predictive value 0.967). When we focused on cases with typical CT images, loss of taste or smell, and close contact with COVID-19 patients were exclusive characteristics for the COVID-19 cases. Among laboratory data, high fibrinogen (P<0.01) and low white blood cell count (P<0.01) were good predictors for COVID-19 with typical CT images in multivariate analysis.
In a relatively low prevalence region, CT screening has high sensitivity to COVID-19 in patients with suspected symptoms. When chest CT findings are typical for COVID-19, close contact, loss of taste or smell, lower white blood cell count, and higher fibrinogen are good predictors for COVID-19.

The aim of this study was to develop pre-procedural intravascular ultrasound (IVUS)-based models for predicting the occurrence of stent underexpansion.
Although post-stenting IVUS has been used to optimize percutaneous coronary intervention, there are no pre-procedural guidelines to estimate the degree of stent expansion and provide preemptive management before stent deployment.
A total of 618 coronary lesions in 618 patients undergoing percutaneous coronary intervention were randomized into training and test sets in a 51 ratio. Following the coregistration of pre- and post-stenting IVUS images, the pre-procedural images and clinical information (stent diameter, length, and inflation pressure; balloon diameter; and maximal balloon pressure) were used to develop a regression model using a convolutional neural network to predict post-stenting stent area. To separate the frames with from those without the occurrence of underexpansion (stent area<5.5mm
), binary classification models (XGBoost) were deve avoid stent underexpansion as a preventable cause of stent failure.
The aim of this study was to investigate age-related outcomes of patients undergoing transcatheter aortic valve replacement (TAVR) as assessed in a nationwide, prospective, multicenter cohort study.
TAVR is the preferred treatment for elderly patients with severe aortic stenosis and is expanding into lower age groups.
Data from the SwissTAVI Registry were analyzed. Clinical outcomes were compared between patients 70 years of age or younger (n=324), 70 to 79 years of age (n=1,913), 80 to 89 years of age (n=4,353), and older than 90 years of age (n=507). KRT-232 inhibitor Observed deaths were correlated with expected deaths in the general Swiss population using standardized mortality ratios.
Between February 2011 and June 2018, 7,097 patients (mean age 82.0 ± 6.4 years, 49.6% women) underwent TAVR at 15 hospitals in Switzerland. Procedural characteristics were similar; however, older patients more often had discharge to the referring hospital or a rehabilitation facility after TAVR. Using adjusted analyses, a linear trend for mortality (30-day adjusted hazard ratio [HR
