, , , , , , To assess the degree of correlation/agreement of maternal-fetal Doppler parameters between normal and growth-restricted fetuses (fetal growth restriction [FGR]).
The present observational and retrospective study included 274 singleton pregnancies. The following maternal-fetal Doppler parameters were assessed: uterine artery (UAt), umbilical artery (UA), middle cerebral artery (MCA), cerebroplacental ratio (CPR), and umbilical-cerebral ratio (U/C). The assessment of FGR was based on the Figueiras and Gratacós9 criteria. Spearman correlation coefficients were estimated to assess the correlation between resistance (RI) and pulsatility (PI) indices of Doppler parameters. The agreement between two Doppler parameters was assessed by the Kappa coefficient.
In total, 502 Doppler examinations were included, and FGR was observed in 19 out of 274 fetuses. A strong correlation was observed between RI and PI of UAt, UA, and MCA in all of the samples (p<0.001). Of the 502 Doppler examinations, there was agreement between U/C and CPR percentiles for 480 (95.6%) and disagreement for 22 (4.4%), with Kappa coefficient of 0.26, thereby corresponding to weak agreement. Of the 68 cases with estimated fetal weight ≤ 9th percentile (small for gestational age [SGA]), there was agreement between U/C>1.0 and CPR<5th percentile in 61 (88.4%) and disagreement in 7 (5.8%) with Kappa coefficient of 0.49, thereby corresponding to moderate agreement.
Strong correlation was observed among RI and PI UAt, UA, and MCA Doppler examinations in the present study; however, weak agreement was observed between U/C and CPR in the normal and FGR fetuses. In SGA, U/C and CPR demonstrated moderate agreement.

, , , , To evaluate the seroprevalence of positive markers for syphilis, human immunodeficiency virus (HIV) I and II, human T cell lymphotropic virus (HTLV) I and II, and hepatitis B and C among women undergoing in vitro fertilization (IVF).
We conducted a retrospective analysis among patients who underwent IVF, between January 2013 and February 2016, and who had complete screening records.
We analyzed 1,008 patients who underwent IVF, amounting to 2,445 cycles. Two patients (0.2%) tested positive for HIV I and II and none for HTLV I and II. Three patients (0.3%) had positive screening for syphilis, and two (0.2%) had positive hepatitis C antibody test (anti-HCV). A positive hepatitis B virus surface antigen (HbsAg) test was observed in 4 patients (0.4%), while 47 (4.7%) patients were positive for IgG antibody to hepatitis B core antigen (anti-HbC IgG), and only 1 (0.1%) was positive for IgM antibody to hepatitis B core antigen (anti-HbC IgM). The anti-HbS test was negative in 659 patients (65.3%). Only 34.7% of the patients had immunity against the Hepatitis B virus. Patients with an anti-HbS negative result were older than those with a hepatitis B test (anti-HbS) positive result (36.3 versus 34.9; p<0.001).
The present study showed lower infection rates than the Brazilian ones for the diseases studied in patients undergoing IVF. Only a few patients were immunized against hepatitis B.

To evaluate the ovarian response after cyclophosphamide use (CPM) in patients
with systemic lupus erythematosus (SLE) and to correlate the age and cumulative
dose findings with changes in menstrual cycle and/or progression to ovarian
failure (OF).
This was a cross-sectional, retrospective study of 50 patients with a diagnosis
of SLE who used CFM with a clinical follow-up of at least 1 year. Included were
patients aged 12-40 years, who had undergone chemotherapy for SLE control and who
had regular menstrual cycles before the beginning of CPM treatment. Patients who
discontinued follow-up, who were followed up for less than one year or who had
irregular/absent menses before the beginning of CPM treatment were excluded. All
women studied were submitted to an interview and a questionnaire containing
questions about the pattern of the menstrual cycle before and after therapy, and
about the gestational periods and contraception. We asked if the patients had been
instructed about the side effects and consequences of CFM. Statistical analysis
was performed using the Student t-test and the Mann Whitney, χ2 and
nonparametric Kolmogorov-Smirnov tests.
The mean age of the patients included in the study was 30.8 years and the mean
age at the time of use of CPM was 25.3 years. After CFM, 24% of patients stopped
menstruating, 28% returned to regular cycles and 48% continued to have irregular
cycles. It was found that the patients who developed OF had longer disease
duration (12.3 years) than those who did not develop it (8.9 years). Thirteen
patients became spontaneously pregnant after CFM; however, 66% progressed to
abortion. The mean age of the patients who used CFM and developed OF was 28.1
years. Amenorrhea occurred in 50% of those aged 31-40 years, in 22.2% of those
aged 21-30 years and in 7.7% of those aged 12-20 years. Our study showed no
statistical correlation between cumulative dose and OF, although cumulative doses
greater than 11grams tended to promote some type of menstrual irregularity.
SLE disease duration, age at the time of treatment and the highest cumulative
doses are important predictors of OF after therapy with CFM. Pregnancy in lupus
patients is more likely to evolve with abortion after the use of chemotherapy. It
was seen that a small proportion of patients were aware of all the implications of
the drug. Therefore, additional studies should be conducted for further knowledge
and awareness of the importance of contraception and the preservation of ovarian
tissue on the part of the medical community.
