Pré-eclâmpsia precoce e tardia: uma classificação mais adequada para o prognóstico materno e perinatal? Early-onset preeclampsia: is it a better classification for maternal and perinatal outcomes?

OBJETIVO: avaliar as diferenças entre o resultado materno e perinatal de gestações complicadas pela pré-eclâmpsia, segundo classificação em sua forma grave/leve e de início precoce/tardio. MÉTODOS: estudo retrospectivo envolvendo 211 gestações complicadas pela pré-eclâmpsia, avaliadas em centro universitário de referência, no período de 2000 a 2010. O diagnóstico e a gravidade da doença foram baseados nos valores da pressão arterial, proteinúria e nos achados clínicos e laboratoriais. A idade da gestante, cor da pele, paridade, pressão arterial, valores de proteinúria semiquantitativa, presença de incisura bilateral em artérias uterinas à doplervelocimetria e as condições de nascimento foram comparados entre os casos de forma leve/grave, assim como entre aqueles de surgimento precoce/tardio. A doença foi considerada precoce quando diagnosticada antes da 34ª semana. RESULTADOS: a maioria das gestantes apresentava a forma grave da pré-eclâmpsia (82,8%) e 50,7%, de início precoce. Os valores da pressão arterial (133,6±14,8 versus 115,4 mmHg, p=0,0004, e 132,2±16,5 versus 125,7 mmHg, p=0,0004) e proteinúria semiquantitativa (p=0,0003 e p=0,0005) foram mais elevados nas formas grave e precoce em relação às formas leve e tardia. O peso ao nascimento (1.435,4±521,6 versus 2.710±605,0 g, 1.923,7±807,9 versus 2.415,0±925,0 g, pPURPOSE: to evaluate the differences between the maternal and perinatal outcomes of pregnancies complicated by preeclampsia, according to the classification as the severe/mild form, and the early/late onset form. METHODS: a retrospective study with 211 pregnancies complicated by preeclampsia, assessed at a university reference center from 2000 to 2010. The diagnosis and disease severity were based on the values of blood pressure, proteinuria, and clinical and laboratory findings. The pregnant's age, skin color, parity, blood pressure, urine protein semiquantitative values, presence of bilateral notch in the uterine artery dopplervelocimetry and birth conditions were compared between patients with mild and severe disease, as well as between those of early/late onset. The disease was considered to be of early onset when diagnosed at less than 34 weeks of gestational age. RESULTS: most patients had the severe form of preeclampsia (82.8%), and the onset of the condition was early in 50.7%. Blood pressure values (133.6±14.8 versus 115.4 mmHg, p=0.0004 and 132.2±16.5 versus 125.7 mmHg, p=0.0004) and semiquantitative proteinuria (p=0.0003 and p=0.0005) were higher in the early and severe forms compared to mild and late forms. Infant birth weight (1,435.4±521.6 versus 2,710±605.0 g, 1,923.7±807.9 versus 2,415.0±925.0 g, p<0.0001 for both) and Apgar score (p=0.01 for both) were smaller for severe and early preeclampsia compared to mild and late preeclampsia. On the other hand, the presence of a bilateral notch in the uterine arteries was linked to the forms of early onset (69.2 versus 47.9%, p=0.02), whereas fetal growth restriction was more frequent in the severe forms of preeclampsia (30 versus 4.4%, p=0.008). CONCLUSION: the preeclampsia classification based on maternal clinical parameters better reflected the conditions of fetal nutrition, while the early onset of the condition was associated with placental vasculopathy detected by dopplervelocimetry

O Jogo Sério 'COVID-19 - Você sabia?' Descrição dos acessos ao jogo após 30 meses de implementação

ABSTRACTIntroduction: From the scenario imposed by the COVID-19pandemic in 2020, it was necessary to have access toinformation as a mode of transmission and prevention of thespread of the new coronavirus, considered critical healthmeasures. Serious games have advantages in disseminatingreliable information during a pandemic, as they can offerqualified content while providing user interactivity and widereach over the internet. Objective: This study aims to presentand analyze the results of using the serious game. Methods:Development was based on Progressive Web App with IonicFramework. Open data reports of how users interact withserious play were taken from the Google Analytics API.Results: The game was made available for free in April2020. The visual identity was developed considering aselection of colors, typography, sounds and images suitablefor the young audience. During 5 semesters of use, therewere more than 32 thousand accesses, the majority (98%)coming from Brazil. Conclusion: The health educationcontent gamification strategy on the topic of COVID-19achieved the proposed objectives

Uromodulin: a new biomarker of fetal renal function?

Abstract Introduction: Obstructive uropathies are main diseases affecting the fetus. Early diagnosis allows to establish the appropriate therapy to minimize the risk of damage to kidney function at birth. Biochemical markers have been used to predict the prognosis of renal function in fetuses. Uromodulin, also known by Tamm-Horsfall protein (THP) is exclusively produced in the kidneys and in normal conditions is the protein excreted in larger amounts in human urine. It plays important roles in kidneys and urinary tract. Also it participates in ion transport processes, interact with various components of the immune system and has a role in defense against urinary tract infections. Moreover, this protein was proved to be a good marker of renal function in adult patients with several renal diseases. Objective: To evaluate if uromodulin is produced and eliminated by the kidneys during fetal life by analyzing fetal urine and amniotic fluid and to establish correlation with biochemical parameter of renal function already used in Fetal Medicine Center at the Clinic Hospital of UFMG (CEMEFE/HC). Methods: Between 2013 and 2015, were selected 29 fetuses with indication of invasive tests for fetal diagnosis in monitoring at the CEMEFE/HC. Results: The determination of uromodulin was possible and measurable in all samples and showed statistically significant correlation with the osmolarity. Conclusion: There was a tendency of lower levels of Uromodulin values in fetuses with severe renal impairment prenatally. Thus, high levels of this protein in fetal amniotic fluid or fetal urine dosages possibly mean kidney function preserved

Longitudinal assessment of D-dimer and plasminogen activator inhibitor type-1 plasma levels in pregnant women with risk factors for preeclampsia

Objective: Investigating D-Dimer/D-Di and plasminogen activator inhibitor type-1/PAI-1 levels throughout gestation in women with preeclampsia/PE risk factors. Methods: D-Di and PAI-1 plasma levels were determined in 28 women at 12–19, 20–29, 30–34 and 35–40 weeks of gestation. Results: D-Di was lower at 12–19 weeks and higher at 30–34 weeks in women who developed PE versus who did not develop it. D-Di increased throughout gestation in both groups, peaking earlier in pregnant women who developed PE versus who did not develop it. PA1-1 increased across gestation, but it didn’t differ between groups. Conclusion: D-Di was able to discriminate these groups of women at 12–19 and 30–34 weeks of gestation.</p
