To investigate the association of perinatal variables with the birth of very low birth weight (VLBW) preterm newborns.
It was a retrospective study of the medical records of infants born after spontaneous preterm labor with admission to a neonatal intensive care unit. Preterm infants were divided into two groups: very low birth weight (VLBW) group (weight <1,500 g) and low birth weight (LBW) group (weight ≥1,500 g and <2,500 g). Prenatal variables such as maternal complications during pregnancy and childbirth/postpartum, and fetal/neonatal complications were investigated. Statistical analysis was performed using the Fisher exact test or χ2 test, with calculation of relative risk (RR), and the Student t test for comparison of group means, with the level of significance set at p≤0.05.
Hemorrhagic comorbidities (p=0.006; RR=1.2) and hypertension (p=0.04; RR=1.5), surgical delivery (p=0.001; RR=0.5), gestational age <33 weeks (p< 0.001; RR=16.7) and Apgar score at 1st and 5th minute (p=0.006; RR=1.6; p=0.01; RR=1.9) were associated with the occurrence of VLBW. Infants with VLBW had a significant association with the occurrence of metabolic comorbidities (p=0.01; RR=1.8), neurological (p=0.01; RR=1.7) and infectious diseases (p=0.001; RR=1.9), hospitalization >4 weeks (p=0.02; RR=1.8) and early neonatal death (p=0.0001; RR=2.9).
Factors such as hypertension and bleeding comorbidities during delivery and management of gestational age of less than 33 weeks were associated with the birth of VLBW newborns. This group of infants also showed higher RR for the occurrence of early neonatal death.

To analyze the serological, anatomopathological and parasitological results obtained from abortive material in order to detect infections with the risk of vertical transmission, with emphasis on toxoplasmosis.
A cross-sectional cohort study was conducted in order to determine the prevalence of infectoparasitic diseases. A total of 105 women who suffered spontaneous complete or incomplete abortion participated in the study. The women were interviewed, answered a questionnaire and had their blood and abortive material collected. Immunological tests were carried out in order to detect toxoplasmosis, Chagas disease, rubeola, cytomegalovirus and syphilis, and anatomopathological analysis of the ovular remains was performed.
55% of the women studied were 20 to 30 years old. Most of them (68%) presented a gestational age between the 7th and 14th week. 54.3% of the women had complete or incomplete high school education. Serological analysis showed cytomegalovirus (CMV) as the most common vertically transmitted infection with 97.1% positivity, followed by rubeola with 95.2%. Toxoplasmosis showed 54.3% positivity, Chagas disease 1.9% and syphilis 0.95%. Anatomopathological analysis showed inflammation in 63.1% of the cases and absence of inflammation in 34%. The results of the serological, anatomopathological and parasitological analysis of the 105 participants showed that 57 women were T. gondii positive. However, none showed positivity in the polymerase chain reaction (PCR) or in mouse inoculation.
The prevalence of diseases with the risk of vertical transmission is important in women with spontaneous abortion, indicating the need for more research in order to investigate the etiology of abortion.

To evaluate changes in body and internal organ weight of autopsied children in the perinatal period and their relationship with the cause of death.
One hundred and fifty three cases of perinatal autopsies performed at a university hospital in Southeastern Brazil ere included. Information about cause of perinatal death, date of autopsy, gestational age, perinatal weight and organ weight was obtained from the autopsy protocols and medical records of the mother and/or the newborn. Four groups of causes of death were defined: congenital malformations, perinatal hypoxia/anoxia, ascending infection and hyaline membrane. Brain, liver, lungs, heart, spleen, thymus and adrenals were analyzed.
The weight of children with perinatal hypoxia/anoxi (1,834.6±1,090.1 g versus 1,488 g), hyaline membranes (1,607.2±820.1 g versus 1,125 g) and ascending infection (1,567.4±1,018.9 g versus 1,230 g) was higher than expected for the population. Lung weight was higher in cases with ascending infection (36.6±22.6 g versus 11 g) and lower in cases with congenital malformations (22.0±9.5 g versus 40 g). Spleen weight was higher in children with ascending infection (8.6±8.9 g versus 3.75 g ) and adrenal weight was lower in cases with congenital malformations (3.9±2.1 g versus 5.5 g). Thymus weight was lower in cases with miscellaneous causes (3.7±1.2 g versus 7.5 g) and spleen weight was lower in patients with lung immaturity (0.4±0.1 g versus 1.7 g). All results showed significant differences.
This study demonstrates that variations in the weight of children and the weight of their organs are related to the types of cause of perinatal death. These data may contribute to a better interpretation of autopsy findings and their anatomical and clinical relationship.

To evaluate the maternal risk factors that require newborn assistance in neonatal Intensive Care Units (ICU).
A prospective observational case-control study was conducted on 222 pregnant women (1:1 case-control ratio) attended at a public maternity. The following variables were analyzed in the puerperae: age at menarche, age at first sexual intercourse, history of chronic diseases, habits, prenatal care, obstetric history, clinical complications during pregnancy and childbirth, and sociodemographic variables. The variables of the newborns were: Apgar scores, gestational age, birth weight, presence or absence of malformation, need for resuscitation, and complications during the first 24 hours. Proportions were compared using the Fisher exact test or the Person γ2 test. Multivariable models were developed by logistic regression analysis using adjusted Odds Ratio with a 95% confidence interval (CI).
Regarding reproductive history, ≥3 pregnancies and 2 or 3 previous cesareans were sytatistically significant (p=0.0 and 0.0, respectively). Among the complications that required assistance in the neonatal ICU, prematurity was responsible for 61 cases (55.5%), followed by risk of intrapartum infection in 46 cases (41.8%). Regarding the maternal history, the presence of hypertensive disease showed statistical significance (p=0.0). Premature rupture of membranes was strongly associated with the need for the neonatal ICU (Odds Ratio - OR=6.1, 95%CI 2.6-14.4).
Premature rupture of membranes and hypertensive disease should receive special attention in prenatal care due to their strong association with newborns requiring assistance in the neonatal ICU.

To analyze the cytological findings of women with cervical adenocarcinoma, taking
into account the patient's history in the year prior to diagnosis and the
histopathological aspects of the lesions.
A retrospective comparative study was conducted using data from women with
cervical adenocarcinoma or squamous carcinoma detected between 2002 and 2008. The
cytological reports were synthesized according to the Bethesda System revised in
2001 and were compared to the histopathological findings of cervical
adenocarcinoma and squamous carcinoma. The distributions of cytological findings
were calculated, as well as the global agreement and chance-corrected agreement
using the Cohen's Kappa Coefficient. For this purpose, the cytological findings
were grouped according to the epithelial origin, forming the glandular cell and
squamous cell groups, with the histopathologically confirmed tumor types
(adenocarcinoma versus squamous carcinoma) being used as the gold
standard.
A total of 284 cases of cervical cancer were diagnosed during the study period.
The effectively studied cases were 27 and 54 patients with adenocarcinoma and
squamous carcinoma, respectively. The adenocarcinoma group represented 9.5% of the
total cases diagnosed, and 56.0% of the women in this group were younger than 50
years. Cervical cytology was collected on average 92 days before the cancer
diagnosis (range: 19 days to 310 days). In 41.6% of cases the cytological results
were consistent with glandular alterations such as adenocarcinoma cells or
atypical glandular cells. The global agreement and Cohen's Kappa Coefficient were
73.7 and 48.7%, suggesting substantial and moderate agreement, respectively.
In this population, the cytological smears had an important role in screening
women with adenocarcinoma, although some of them were referred to clarify the
clinical symptoms. The agreement between cytological and histopathological
findings was moderate.

To analyze and compare the knowledge, attitudes and opinions of medical students about abortion in Brazil during the progression of the course.
This was a cross-sectional study involving 174 medical students. A questionnaire was applied whose dependent variables were degree of information about abortion, including its legal aspects in Brazil, situations in which the students would agree with the expansion of permitted legal abortion, knowledge of someone undergoing abortion, and discomfort about performing the procedure legally. The independent variables were sociodemographic data, religion, and academic standing (first or second half of the course). For data analysis it was used χ2 and Fisher's exact tests, with the level of significance set at 5%.
Among the interviewees, 59.8 % considered themselves well informed about the topic. Students demonstrated knowledge about the complications of abortion, with no differences with the progression of the course. Knowledge about the legal aspects of abortion in Brazil was shown by 48.9% of the sample, being significantly higher among students in the second half of the course (34.0 and 68.9%, respectively; p<0.001). Experiencing situations of clandestine abortion was significantly higher among students in the final half of the course (3.05 and 59.4%, respectively; p<0.001), the same being observed about knowing someone who underwent the procedure illegally (5.0 and 18.9%, respectively; p<0.001). The expansion of permissive legal abortion in Brazil was agreed about by 86.2% students, although 54.6% of the students reported that they felt uncomfortable about performing the procedure even legally, without statistical significance with the evolution of the course regarding the two situations.
The experiences of abortion and the knowledge of legal aspects were significantly higher among students in the second half of the course, with no significant changes in attitudes or opinions about abortion being observed with the competences acquired during medical training.
