The simple right ventricular contraction pressure index (sRVCPI) is a new echocardiographic variable for estimating the right ventricular systolic function. Our aim was to investigate the association between the sRVCPI, the pulmonary embolism severity index (PESI), and mortality rate in acute pulmonary embolism (APE).

We included in this study 116 patients diagnosed with APE by pulmonary computed tomography angiography or ventilation/perfusion scintigraphy. They were divided into two groups based on the simplified PESI < or >1. Tricuspid regurgitation velocity and TAPSE were measured and used for sRVCPI calculation.

Mortality was higher in patients with a higher sRVCPI (P < .001). In receiver operating characteristic (ROC) curve analysis using a cut-off level of 312.8 mm Hg mm, sRVCPI predicted mortality with a sensitivity of 86.8% and specificity of 69.5% (ROC area under curve 0.712; 95%CI 0.597-0.882; P < .001). The sRVCPI was lower in the sPESI >1 than in the sPESI <1 group (364.3 ± 31.9 vs 511.6 ± 26.1; P < .001). There was an inverse correlation between sRVCPI and the sPESI score (-0.784; P < .001).

The sRVCPI correlated with the sPESI score and was associated with mortality in patients with APE. This easily measurable variable may be used to predict short-term mortality in APE patients.

Diastolic dysfunction (DD) and pulmonary hypertension (PH) are common causes of mortality for sickle cell disease (SCD) patients in developed countries. We hypothesized that left and right atrial strain (LAS-Ɛ, RAS-rƐ) are decreased in SCD adolescents, and that worsening values correlate with laboratory markers of disease severity.

Prospective cohort study of patients with HbSS genotype of SCD was compared with healthy controls. LAS and RAS were measured from 4- and 2-chamber views by a blinded reader. Peak strain and strain rate values were obtained for atrial contraction (ac), reservoir (res), and conduit (con) phases. Mitral/tricuspid Doppler velocities, left atrial volume, right atrial area were obtained. Laboratory variables were obtained from the electronic record with the three prior values being averaged. Differences in variables were assessed with Wilcoxon rank sum test, and correlations assessed with Spearman's coefficient.

There were 33 SCD patients compared to 35 healthy controls of similar age, gender, and size. SCD patients had increased left atrial volume and right atrial area. For LAS, Ɛres was significantly lower in SCD patients. For RAS, RƐcon was significantly lower. Neither measurement correlated with clinical markers. The majority of SCD patients had relatively normal atrial strain values. Those with markedly lower values had similar atrial size.

A sub-set of SCD patients have markedly low Ɛres and rƐcon. No correlation with clinical markers was identified. Larger, longitudinal studies may determine utility of atrial strain as a screening tool in this at-risk population.

Fish is the most common causative food of food protein-induced enterocolitis syndrome (FPIES) in Southern Europe. In children with FPIES, the development of tolerance varies according to the culprit food and specifically fish seems to have a poorer prognosis than other solid foods. We sought to evaluate the fish-FPIES resolution rate in children.

A descriptive retrospective analysis of children with fish-FPIES, followed during the last 20years, was performed. The offending fish, age and symptoms at onset, the coexistence of atopic diseases and FPIES to other foods were registered. All the children included had undergone an oral food challenge (OFC) with the offending fish. We recorded those children that overcame their fish-FPIES and those that did not outgrow the disease.

Seventy children were enrolled in this study (median age 9yo; IQR 6.4-13.8). Forty-two (60%) achieved tolerance to the offending fish with a median age of 4years (IQR 3-5). Among children ≤5yo (n=40), 35 (87.5%) developed tolerance; among 6-8yo (n=14), 40% developed tolerance; and only 12.5% among those ≥9yo (n=16) developed tolerance. Twenty-eight children did not outgrow the disease (median age 8.9 yo; IQR 9-13.8). We did not find any statistical differences regarding the offending fish, presence of single vs multiple fish-FPIES, symptoms at the beginning, coexistence of other atopic diseases or the coexistence of other FPIES, between the children who overcame the disease and those who did not.

One in five children with FPIES to fish will not overcome the disease during childhood.

Raw ewe's milk, as used to manufacture Serra da Estrela Protected Designation of Origin cheese, was pre-treated by high pressure processing (HPP), using previously optimized conditions (121 MPa for 30 min), aiming to evaluate its effect on milk technological properties for subsequent cheese production, namely the impact on resulting curd, whey and cheese throughout ripening.

The cheese yield increased 10.4% as a result of milk pre-treated by HPP, which also yielded inactivation of beneficial microbial groups. After 60 days of ripening, both treated and control cheeses showed no significant differences (P ≥ 0.05) with respect to quantified microbial load or basic physicochemical quality parameters.

HPP appears to be a promising non-thermal treatment for ewes' milk to inactivate contaminant bacteria but with no negative effect on lactic acid bacteria, which is very important for the unique characteristics of Serra da Estrela cheese. SB290157 purchase © 2020 Society of Chemical Industry.
