ReviewPerioperative cardiovascular evaluation: heads or tails?
When dealing with surgical patients, a perioperative evaluation is essential to anticipate complications and institute measures to reduce the risks. Several algorithms and exams have been used to identify postoperative cardiovascular events, which account for more than 50% of perioperative mortality. However, they are far from ideal. ⋯ The ankle-brachial index is another significant marker of atherosclerosis. However, specific information regarding the perioperative context of all these methods is still needed. The objective of this article is to evaluate cardiovascular risk prediction models after noncardiac surgery.

Profile of women admitted at an obstetric ICU due to non-obstetric causes.
To characterize patients admitted during the pregnancy-puerperal cycle for non-obstetric causes in the obstetric intensive care unit (ICU) of a tertiary hospital in northeastern Brazil. ⋯ Women admitted at the obstetric ICU due to non-obstetric causes represent a significant number of patients in this sector. They are mostly young women, and the main admission diagnoses were cardiovascular, respiratory, and infectious diseases, with a fatality rate of 4%.

Comparative StudyDepression, emotional and social aspects in the abortion context: a comparison between two Brazilian capitals.
To assess emotional and social aspects in the experience of abortion and the diagnosis of major depression, comparing women from two Brazilian cities (São Paulo--SP, Natal--RN). ⋯ Although there was no difference between the emotional and social aspects in the comparison between the two capitals, there was a high proportion of women with major depression, more frequent in the city of Natal than in São Paulo, which demonstrates the importance of psychosocial support in the women's healthcare system.

ReviewAtypical glandular cells and cervical cancer: systematic review.
Atypical glandular cells are a common finding in cervical cytology in cervical cancer screening and its occurrence has increased in the last decades. The identification of these cells is clinically very important due to its association with cervical and endometrial dysplasic lesions and cancer. Using a systematic approach, this article reviewed studies investigating cervical lesions that are characteristic in patients previously diagnosed as having atypical glandular cells. ⋯ Nineteen articles met the inclusion criteria and were selected. This report aims at evaluating whether atypical glandular cells, initially found in cervical cytology and subsequently identified at the histological analysis, are related to the presence of benign, pre-malignant and malignant lesions. Eleven out of 19 selected articles showed the highest correlation between atypical glandular cells with benign diseases and six with squamous pre-malignant lesions.

Review[The molecular basis of RH system and its applications in obstetrics and transfusion medicine].
The Rh system is the most polymorphic and immunogenic for all blood group systems. Currently more than 49 antigens were identified with five major antigens D, C, c, E, e. ⋯ In Caucasians the primary mechanism of Rh-negative phenotype is the complete RHD gene deletion, while in African descendants it is the presence of pseudogene and gene RHDψ hybrid RHD-CE (4-7)-D. The authors analyze the structure of the Rh complex in red cells, molecular basis of the Rh system, mechanisms of Negativity RHD and weak and incomplete expression of RHD.
