Previous research shows a correlation between the levels of vitamin D in patients infected with SARS-CoV-2 and the degree of disease severity. This work investigates the impact of the genetic background related to vitamin D pathways on COVID-19 severity. For the first time, the Portuguese populatio...
The effect of the woman's age, the rate of cleavage and embryo quality on obtai...
Cordeiro, I; Calhaz-Jorge, C; Barata, M; Leal, F; Proença, H; Coelho, A MMultiple factors influence the probability of obtaining a pregnancy through in vitro fertilization (IVF) and embryo transfer (ET). This retrospective study was designed to assess their importance in order to improve prognostic ability and treatment success. 341 consecutive embryo transfer cycles using the same ovarian stimulation protocol were considered and divided in two main groups: 92 cycles in which a clin...
Urinary calcium, magnesium and uric acid in normal children.
Araujo e Sá, G; Proença, H; Sassetti, L; Lopes, S; Barros, F B; Rosa, F CIn a group of 327 normal children, aged 4 to 11, we measured Calcium (Ca) and Creatinine (Cr) in the second morning urine. In 226 of them, Magnesium (Mg) and Uric Acid (UA) were also calculated. Means and SD were respectively Ca/Cr: 0.11 +/- 0.09, Mg/Cr: 0.10 +/- 0.03, Mg/Ca: 1.56 +/- 1.48 and UA/Cr: 0.093 +/- 0.29. Distribution was not normal, so we used the 97.5 centile for the upper acceptable limit. This va...
