OBJETIVO: Avaliar a sobrevida e complicações associadas à prematuridade em recém-nascidos com menos de 32 semanas. MÉTODOS: Estudo prospectivo do tipo coorte. Foram incluídos os nascidos vivos, com idade gestacional entre 25 semanas e 31 semanas e 6 dias, sem anomalias congênitas admitidos em UTI Neonatal, entre 1º de agosto de 2009 e 31 de outubro de 2010. Os recém-nascidos foram estratificados em três grupos: G25, 25 a 27 semanas e 6 dias; G28, 28 a 29 semanas e 6 dias; G30, 30 a 31 semanas e 6 dias, e acompanhados até 28 dias. Foram avaliadas a sobrevida aos 28 dias e a morbidade associadas à prematuridade. Para análise dos resultados, utilizou-se o teste do c², análise de variância, teste de Kruskal-Wallis, razão de risco com intervalo de confiança (IC) e regressão logística múltipla, com significância em 5%. RESULTADOS: A coorte compreendeu 198 prematuros, sendo G25=59, G28=43 e G30=96. O risco de óbito foi significativamente maior em G25 e G28, em relação ao G30 (RR=4,1; IC95% 2,2-7,6 e RR=2,8; IC95% 1,4-5,7). A sobrevida encontrada foi, respectivamente, 52,5, 67,4 e 88,5%. A partir da 26ª semana e peso >700 g, a sobrevida foi superior a 50%. A morbidade foi inversamente proporcional à idade gestacional, exceto para enterocolite necrosante e leucomalácia, que não diferiram entre os grupos. A análise de regressão logística mostrou que a hemorragia pulmonar (OR=3,3; IC95% 1,4-7,9) e a síndrome do desconforto respiratório (OR=2,5; IC95% 1,1-6,1) foram fatores independentes de risco para óbito. Houve predomínio das lesões cerebrais hemorrágicas graves em G25. CONCLUSÕES: Sobrevivência superior a 50% ocorreu a partir da 26ª semana de gravidez e peso >700 g. A hemorragia pulmonar e a síndrome do desconforto respiratório foram preditores independentes de óbito. Há necessidade de identificar e instituir práticas para melhorar a sobrevida de prematuros extremos.

PURPOSE: To compare obstetric outcomes of induced preterm twin births (under 32 weeks gestation) with those spontaneously conceived. METHODS: Prospective study of twin pregnancies (25 induced and 157 spontaneously conceived) developed over a period of 16 years in a tertiary obstetric center. Demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were compared. RESULTS: The analysis of obstetrical complications concerning urinary or other infections, hypertensive disorders of pregnancy, gestational diabetes, fetal malformations, intrauterine fetal death, intrauterine growth restriction and intrauterine discordant growth reveal no significant statistical differences between the two groups. First trimester bleeding was higher in the induced group (24 versus 8.3%, p=0.029). The cesarean delivery rate was 52.2% in spontaneous gestations and 64% in induced gestations. Gestational age at delivery, birth weight, Apgar scores at first and fifth minutes, admissions to Neonatal Intensive Care Unit and puerperal complications show no statistically significant differences between the two groups. These results were independent of chorionicity and induction method. CONCLUSION: The mode of conception did not influence obstetric and neonatal outcomes. Although induced pregnancies have higher risk of first trimester bleeding, significant differences were not observed regarding other obstetric and puerperal complications and neonatal results.

The connexin 32 (Cx32) is a protein that forms the channels that promote the gap junction intercellular communication (GJIC) in the liver, allowing the diffusion of small molecules through cytosol from cell-to-cell. Hepatic fibrosis is characterized by a disruption of normal tissue architeture by cellular lesions, and may alter the GJIC. This work aimed to study the expression and distribution of Cx32 in liver fibrosis induced by the oral administration of dimethylnitrosamine in female Wistar rats. The necropsy of the rats was carried out after five weeks of drug administration. They presented a hepatic fibrosis state. Sections from livers with fibrosis and from control livers were submitted to immunohistochemical, Real Time-PCR and Western-Blot analysis to Cx32. In fibrotic livers the Cxs were diffusely scattered in the cytoplasm, contrasting with the control livers, where the Cx32 formed junction plaques at the cell membrane. Also it was found a decrease in the gene expression of Cx32 without reduction in the protein quantity when compared with controls. These results suggest that there the mechanism of intercellular communication between hepatocytes was reduced by the fibrotic process, which may predispose to the occurrence of a neoplastic process, taken in account that connexins are considered tumor suppressing genes.

Tutkielmassa tarkastellaan veronkorotuksen määräämistä verotusmenettelystä annetun lain (VML) 32.3 §:n perusteella oikeuskäytännön valossa. Kyseisen pykälän perusteella määrätään ankarimmat veronkorotukset ja veronkorotus voi olla 0-30 prosenttia tuloon lisätystä määrästä. Tutkielman perusteella oikeuskäytännön valossa veronkorotus voidaan määrätä VML 32.3 §:n perusteella mikäli on osoitettavissa, että verovelvollinen on ollut tietoinen tekemästään virheestä esimerkiksi aiemman ohjauksen perusteella tai, mikäli verovelvollisen olisi pitänyt olla tietoinen tekemästään virheestä esimerkiksi asian verotuksellisen selvyyden vuoksi ja hänen voidaan tästä syystä katsoa toimineen törkeästä huolimattomuudesta. Mikäli asia kuitenkin on tulkinnanvarainen tai verovelvollinen on todistettavasti pyrkinyt selvittämään asiaa, veronkorotus ei tule määrättäväksi VML 32.3 §:n perusteella. Veronkorotus voidaan määrätä, mikäli tehdyllä virheellä on vaikutusta verovelvollisen verotettavaan tuloon ja korotuksen tulisi olla korkeintaan noin 5 prosenttia lisätystä tulosta. Oikeuskäytännön valossa verotusmenettelyn yhteydessä määrättävät veronkorotukset ovat yleisesti ottaen liian korkeita ja verohallinnon ohjeistusta tulisi tältä osin muuttaa paremmin lainsäädäntöä ja oikeuskäytäntöä vastaavaksi.
