Patients with congenital heart disease are surviving well into adulthood thanks to advances in medical and clinical care. We present a patient with Ebstein anomaly who underwent surgical tricuspid valve replacement and suffered early valve stenosis due to her unique anatomy. This case highlights the importance of the "unnatural" anatomy that can be encounter in this challenging patient population.
Recently, data from temporal dispersion of myocardial repolarization analysis have gained a capital role in the sudden cardiac death risk stratification. Aim of this study was to evaluate the influence of heart rate, autonomic nervous system, and controlled breathing on different myocardial repolarization markers in healthy subjects.
Myocardial repolarization dispersion markers from short-period (5 minutes) electrocardiogram (ECG) analysis (time and frequency domain) have been obtained in 21 healthy volunteers during the following conditions free breathing (rest); controlled breathing (resp); the first 5 minutes of postexercise recovery phases (exercise
), maximum sympathetic activation; and during the second 5 minutes of postexercise recovery phases (exercise
), intermediate sympathetic activation. Finally, we analyzed the whole repolarization (QTe), the QT peak (QTp), and T peak - T end intervals (Te).
During the exercise
, major part of repolarization variables changed in comparison to the restbjects, whereas they do not alter any spectral components.
Cardiovascular complications related to coronavirus disease 2019 (COVID-19) have led to the need for echocardiographic services during the pandemic. The present study aimed to identify the echocardiographic findings in hospitalized COVID-19 patients and their utility in disease management.
We included patients who were diagnosed with COVID-19 using polymerase chain reaction and those who underwent echocardiographic examination during their hospitalization.
Altogether, 45 patients were evaluated. The mean age was 61.4±12.2years. Hypertension (n=29, 64%) and diabetes mellitus (n=25, 55%) were the most common comorbidities followed by congestive heart failure (n=11, 24%), coronary artery disease (n=9, 20%), and valvular heart disease (n=3, 7%). Eight patients (18%) showed evidence of myocardial injury, as suggested by elevated troponin levels. Brain natriuretic peptide was elevated in 14 patients (36%), and 14 patients had left ventricular dysfunction in the form of reduced ejection fraction (31%). Right ventricular (RV) dilatation was observed in six patients, and five patients had reduced RV ejection fraction. RV pressure and volume overload were observed in three patients. RV thrombus was observed in one patient. Pulmonary pressure was elevated in 10 patients (24%).
Two-dimensional echocardiography can be an important bedside tool for the assessment of cardiovascular abnormalities and hemodynamic status of COVID-19 patients.

The use of nanomaterials for the efficient delivery of active species in viticulture is still an unexplored opportunity. Nitrogen, an essential nutrient for grapevine development and wine quality, is commonly provided in the form of urea. However, the application of conventional fertilisers contributes to nitrate leaching and denitrification, thus polluting groundwater and causing a serious environmental impact. Nanotechnology is offering smart solutions towards more sustainable and efficient agriculture. In the present work, we assessed the efficiency of nontoxic amorphous calcium phosphate (ACP) nanoparticles as nanocarriers of urea (U-ACP) through field experiments on Tempranillo grapevines. Four treatments were foliarly applied U-ACP nanofertiliser (0.4 kg N ha
), commercial urea solutions at 3 and 6 kg N ha
(U3 and U6) and a control treatment (water).
The grapes harvested from plants treated with U-ACP and U6 provided similar levels of yeast assimilable nitrogen, despite the very large reduction al impact. © 2020 Society of Chemical Industry.
People with migraine exhibit postural control impairments. These patients also have an increased light sensitivity due to the disease, and it remains during the headache-free period. Epacadostat datasheet It is currently unknown if increased lighting levels can alter the balance control, especially in individuals with visual hypersensitivity, such as migraineurs. This study aimed to assess the balance and photophobia of women with migraine and non-headache controls under different light conditions.
This cross-sectional study consisted of 14 women with migraine (mean±SD 30.6±8.1 years old) and 14 women without any kind of headache (mean±SD 27.2±2.8years old) screened from a tertiary headache clinical hospital and the local community. Quiet standing balance was evaluated during bipodal and unipodal support, under 3 light conditions ambient (AMB) - 270 lx, visual discomfort threshold (VDT) - 400 lx, and intense visual discomfort (IVD) - 2000 lx. Sway area of the center of pressure was processed and compared between groups. The asl PR=5.50 (1.48 to 20.42), P=.010) lighting conditions.
Photophobia might be a disturbing factor that worsens the balance of patients with migraine during the quiet standing posture.

Various physicochemical parameters, the polyphenolic content, the volatile fraction as well as the sensory profile of beers were studied using five different yeast strains (three top-fermentation and two bottom-fermentation) and two different fermentation temperatures (12 and 18 °C) for each of them.
The results indicated that at lower fermentation temperatures, the yeast strain factor was less significant for the various physicochemical parameters considered. The polyphenolic content increased as the fermentation temperature decreased, and significantly higher amounts of tyrosol were found in the samples fermented at 12 °C. However, the volatile content increased for beers fermented at 18 °C, these beers being better evaluated from the sensory point of view.
No clear relationship was observed between the temperature used and the type of yeast, with more complex aroma and sensory profiles being found in beers fermented at higher temperatures, using yeasts that are supposedly suitable for use at lower temperatures.
