A modified lung ultrasound score to evaluate short-term clinical outcomes of bronchopulmonary dysplasia.

Background: Lung ultrasound (LUS) is a useful tool for assessing the severity of lung disease, without radiation exposure. However, there is little data on the practicality of LUS in assessing the severity of bronchopulmonary dysplasia (BPD) and evaluating short-term clinical outcomes. We adapted a LUS score to evaluate BPD severity and assess the reliability of mLUS score correlated with short-term clinical outcomes.

Echocardiography evaluation of bronchopulmonary dysplasia-associated pulmonary hypertension: a retrospective observational cohort study.

Background: Echocardiography has poor accuracy in grading the severity of pulmonary hypertension (PH) compared to cardiac catheterization. However, the relationship between degree of PH and prognostic outcomes remains uncertain. Our primary objective was to determine whether echocardiogram-assessed PH severity is associated with mortality and hospital readmission in the first year of life.

Folic Acid Supplementation in Chinese Peri-conceptional Population: Results from the SPCC Study.

Objective: To determine the prevalence and determinants of folic acid (FA) supplementation in Chinese couples planning for pregnancy and in women during early pregnancy.

Methods: This was a cross-sectional study based on the Shanghai PreConception Cohort (SPCC) study. Data on FA supplementation and socio-demographic features were collected using questionnaires.

[Study on the oxidative coupling of p-amino-N,N-dimethylaniline with 1-amino-8-naphthol-3,6-disulfonic acid and its application].

A new catalytic spectrophotometic method for the determination of trace chromium (VI) is reported in this paper. The method is based on the catalytic action of chromium (VI) on the oxidative coupling of p-Amino-N,N-dimethylaniline dihydrochloride and 1-Amino-8-naphthol-3,6-disulfonic acid to form a colored dye (lambda max = 516 nm) in the presence of hydrogen peroxide. The mechanism of the reaction was discussed and its optimum conditions were established.
