OBJECTIVE  The aim of this study is to assess the impact of specialized pediatric palliative care (PPC) on neonates with life-limiting conditions compared to standard care. STUDY DESIGN  MEDLINE, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, Scopus, and Embase databases were searched from January 2000 to September 2018. Randomized clinical trials, experimental or observational studies, and secondary administrative database analyses published in English, Spanish, French, and German were included. Two independent reviewers extracted data, and used the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool for quality analysis. Discrepancies were resolved as a team. RESULTS  From the 37,788 records obtained, only eight articles met the inclusion criteria. A meta-analysis was not possible due to the heterogeneity in how the outcomes were defined; however, a qualitative synthesis of the results was possible; organizing outcomes into eight different categories psychological, social and spiritual support; communication; location of care; symptom management; bereavement care; predicted versus actual neonatal outcomes; and parental coping, stress, and satisfaction. CONCLUSION  Specialized versus may have an impact on neonates with life-limiting conditions and their families. More studies that evaluate the impact of specialized versus in neonates with sound statistical analysis is warranted.

STUDY DESIGN  This is a retrospective cohort study of triplet pregnancies from 2007 to 2014. Maternal data were manually collected and assessed until 6 weeks postpartum, and neonatal data were assessed until hospital discharge or death. RESULTS  Eighty-two triplet pregnancies were identified with 246 babies born. Mean gestational age at delivery was 32.3 (standard deviation [SD] ± 3.6) weeks and average birth weight was 1,726 g (SD ± 500). There were 12 perinatal deaths and 25 (10.2%) infants diagnosed with a congenital anomaly. Prior preterm birth and nulliparity had a negative impact on gestational age at delivery (p = 0.016) as compared with prior full-term births. Pregnancy complications (preeclampsia or hypertensive disorders [46.3%], gestational diabetes [28%], postpartum hemorrhage [9.8%], and blood transfusions [8.5%]) also impacted gestational age at delivery (33.0 vs. 34.0 weeks, p = 0.031). Spontaneous conception, chorionicity, and maternal medical problems did not have an impact on median gestational age. CONCLUSION  Nulliparity and presence of pregnancy complications are pertinent to triplet outcomes. This study provides valuable information for anticipatory guidance and preconception counseling to patients considering artificial reproductive technology.

TH acts via the TH receptors (TR) α and β. Lithocholic acid molecular weight By binding to thyroid hormone responsive elements (TREs) on the DNA, TRs regulate expression of TH target genes. Thus, TRs are mainly characterized as ligand dependent transcription factors and regulation of gene expression and protein synthesis is considered the canonical mode of TH/TR action. The demonstration that the ligand-bound TRs α and β also mediate activation of the phosphatidylinositol-3-kinase (PI3K) pathway established noncanonical TH/TR action as an additional mode of TH signaling. Recently, TR mutant mouse models allowed to determine the underlying mode of TH/TR action, either canonical or noncanonical TH/TR signaling, for several physiological TH effects in vivo Regulation of the hypothalamic-pituitary-thyroid axis requires DNA-binding of TRβ, whereas hepatic triglyceride content appears to be regulated by noncanonical TRβ signaling. TRα mediated effects in bone development are dependent on DNA-binding, whereas several cardiovascular TRα effects are rapid and independent from DNA-binding. Therefore, noncanonical TH/TR action contributes to the overall effects of TH in physiology. © Georg Thieme Verlag KG Stuttgart · New York.in English, Portuguese Este relato descreve um caso de bloqueio atrioventricular completo (BAVC) diagnosticado com 25 semanas de gestação em uma mulher com síndrome de Sjögren e anticorpos anti-Ro/SSA positivos. Esteroides fluoretados (dexametasona e betametasona) e terbulina foram utilizados para aumentar a frequência cardíaca fetal, mas o bloqueio cardíaco fetal não foi reversível, e a administração dos medicamentos foi interrompida devido a efeitos colaterais maternos. Ecocardiogramas fetais de acompanhamento foram realizados, e o feto evoluiu com derrame pericárdico, presença de fibroelastose no ventrículo direito, e disfunção ventricular. A interrupção da gravidez por cesariana foi indicada com 34 semanas, e um marca-passo cardíaco foi implantado no recém-nascido do sexo masculino imediatamente após o nascimento. A terapia para fetos com BAVC é controversa, principalmente no que diz respeito ao uso ou não de corticosteroides; no entanto, o monitoramento do intervalo atrioventricular pela ecocardiografia fetal deve ser feito em fetos de mulheres grávidas com autoanticorpos positivos anti-Ro/SSA e/ou anti-La/SSB para impedir a progressão para o BAVC.in English, Portuguese OBJETIVO  Identificar as estratégias e recomendações atuais para profilaxia de tromboembolismo venoso associado ao ciclo gravídico-puerperal, condição de alta morbimortalidade entre mulheres. MéTODOS  A busca na literatura ocorreu entre maio e outubro de 2019, com pesquisa na base de dados do PubMed, contemplando trabalhos publicados nos idiomas português, inglês e espanhol. Os termos thromboembolism (Mesh) AND pregnancy (Mesh) OR postpartum (Mesh) foram utilizados como descritores, incluindo ensaios clínicos randomizados, metanálises, revisões sistemáticas e diretrizes publicadas entre 2009 a 20019, apresentando estratégias de prevenção de tromboembolismo venoso durante a gravidez e o pós-parto. RESULTADOS  Oito artigos abordando estratégias de tromboprofilaxia primária e secundária durante a gestação, parto e puerpério foram selecionados para a presente revisão sistemática. Muitos estudos avaliados foram excluídos por não abordarem estratégias de prevenção.
