ABSTRACT
Abstract Significant attention to palliative care in terminally ill patients has only been effective in Brazil since the year 2000, although there have been isolated actions since the 1980s. When the case involves fetuses or neonates unable to cure, communication and care with the family members only received attention and effective organization starting in 2017. Notably in the years 2015 and 2016 there was an epidemic of microcephaly and along with the persistent crisis of drug users has raised the indices of malformations to a level higher than 3 % of the world average. Here we aim the evaluation of: a) social, educational and spiritual profile of the mothers; b) structure of the specific teams related to palliative care in neonatology; c) recommendations and protocols currently used in the country. The method used is an electronic retrospective on databases and government data; evaluation of the location and composition of palliative care teams in the country. The data found clearly point out that for Brazilian women, the characteristics of regionality in the country, educational level, religiousness and quality of life directly influence pregnancy and the acceptance or not of the possibility of death, directly influencing perinatal palliative care, which, by the way, is still developing methodologies for this type of action.
ABSTRACT
Cervical cancer (CC) is one of the most common cancers among women worldwide. The relation of the human papillomavirus (HPV) with CC and its precursor lesions was first suspected for over 40 years. The indoleamine 2,3 dioxygenase (IDO) is an immune modulator enzyme responsible for the immune system tissue protection mechanism, which may be the key to the tumoural persistence. HPV oncoprotein E7 promotes the increase in cyclin-dependent kinase inhibitor p16 (CDKN2A/p16). The isolated and combined analysis of CDKN2A/p16 mRNA to CC diagnosis was done with promising results. The aim of this study is to evaluate the correlation between IDO mRNA and CDKN2A/p16 mRNA. We will explore the potential of both as diagnostic tools. RNA was extracted from tissue samples. cDNA was generated with High Capacity RNA-to-cDNA kit. The real-time PCR results were analysed using nonlinear curve estimation, ROC curve, Chi-squared test, the proportion of variance explained and Galen and Gambino formulas. From 270 patients attended, colposcopy examination was performed in 110 and the biopsy in 75 patients. We found a positive correlation in patients older than 28 years old with low-risk lesions, but the correlation is lost in high-risk lesions. Although cytology, IDO mRNA and CDKN2A/p16 mRNA could not differentiate the risk groups, IDO combined with CDKN2A/p16 mRNA results could (p = 0.028). The best diagnostic result was achieved by IDO coupled with CDKN2A/p16 mRNA, which may considerably increase the sensitivity of screening for CC.
