To reduce the percentage of cesareans among pregnant women at UNIMED Jaboticabal by redesigning the care delivery model.
Descriptive study conducted at an institution in São Paulo State starting in 2012 to propose the redesign of the care mode based on Continued Improvement Science adapted to the health area. To measure the results of changes we selected nine indicators and their targets.
The percentage of natural births reached the target of 40% after seven months of implementation of the interventions. The percentage of natural births reached 66% among pregnant women in SUS. The perinatal mortality rate decreased by 25% from 2012 to 2014, and the prematurity rate was 3 per 100 live births in 2014. The percentage of pregnant women from UNIMED with six or more prenatal consultations reached 95%. The hospital costs for childbirth care decreased by 27% compared to 2012 and 2013. This reduction was not sustainable and the per capita cost returned to the same level in 2014. The remuneration of all obstetricians increased by 72% from 2012 to 2014.Unimed's costs attributed to the neonatal intensive care unit (NICU) decreased by 61% from 2012 to 2013. The cost was the same for 2013 as it was for 2014 while the admission rate among newborns at UNIMED decreased by 55%. The percentage of pregnant women participating in courses to prepare for birth did not reach the goal set at 80%. The percentage of pregnant women satisfied and very satisfied with care delivery reached 86%.
This project achieved its objectives by reducing the percentage of C-sections among pregnant women of UNIMED Jaboticabal representing a concrete example of achieving the Triple Aim in health: to improve the experience of care and the health outcomes of populations and individuals and to perform these two tasks at a lower cost.

To analyze the obstetrical and neonatal outcomes of pregnancies with small for gestation age fetuses after 35 weeks based on umbilical cord nucleated red blood cells count (NRBC).
NRBC per 100 white blood cells were analyzed in 61 pregnancies with small for gestation age fetuses and normal Doppler findings for the umbilical artery. The pregnancies were assigned to 2 groups: NRBC≥10 (study group, n=18) and NRBC<10 (control group, n=43). Obstetrical and neonatal outcomes were compared between these groups. The χ2 test or Student's t-test was applied for statistical analysis. The level of significance was set at 5%.
The mean±standard deviation for NRBC per 100 white blood cells was 25.0±13.5 for the study group and 3.9±2.2 for the control group. The NRBC≥10 group and NRBC<10 group were not significantly different in relation to maternal age (24.0 versus 26.0), primiparity (55.8 versus 50%), comorbidities (39.5 versus55.6%) and gestational age at birth (37.4 versus 37.0 weeks). The NRBC≥10 group showed higher rate of caesarean delivery (83.3 versus 48.8%, p=0.02), fetal distress (60 versus 0%, p<0.001) and pH<7.20 (42.9 versus 11.8%, p<0.001). The birth weight and percentile of birth weight for gestational age were significantly lower on NRBC≥10 group (2,013 versus 2,309 g; p<0.001 and 3.8 versus 5.1; p=0.004; respectively). There was no case described of 5th minute Apgar score below 7.
An NRBC higher than 10 per 100 white blood cells in umbilical cord was able to identify higher risk for caesarean delivery, fetal distress and acidosis on birth in small for gestational age fetuses with normal Doppler findings.

To evaluate the effectiveness of an illustrated home exercise guide targeting the pelvic floor muscles in promoting urinary continence during pregnancy.
A randomized clinical trial was performed with 87 participants, evaluated six times during pregnancy and divided into three groups: Gsup, supervised; Gobs, not supervised, and Gref, women who did not perform the home exercises program. A miction diary and perineometry were used to evaluate urinary incontinence (primary outcome) and pelvic floor muscle strength (secondary outcome), respectively. The Kruskal-Wallis test with post hoc Dunn's and chi-square and Z tests with Bonferroni correction were used for continuous variables and proportions, respectively, with the level of significance set at 5%.
At the end of the study, 6.9% of pregnant women in the Gsup and Gobs had urinary incontinence, while 96.6% of Gref women were incontinent. Regarding pelvic floor muscle function, Gsup and Gobs had mean contractions of 10 and 8.9 cmH2O, respectively, while Gref had a value of 4.7 cmH2O. Both results were significant.
An illustrated home exercise guide targeting the pelvic floor muscles is effective in promoting urinary continence during pregnancy, even without permanent supervision.

The administration of a single-course antenatal corticosteroid treatment is recommended for pregnant women between 24 and 34 weeks with risk of premature birth. The maximum effect is achieved when antenatal corticosteroids are administered between 24h and 7 days before delivery. The objective of this study was to evaluate the occurrence of birth within seven days of corticosteroid therapy in major obstetric situations with risk of preterm birth
Retrospective cohort study including 209 pregnant women hospitalized in risk of preterm delivery, submitted to corticosteroid therapy for fetal lung maturation. The study was carried out between January 2012 and March 2014 at a university hospital. Main outcome measure was the number of women who delivered within 7 da ys after antenatal corticosteroid administration. Two groups were defined according to the reason for starting corticosteroids: threatened preterm labour (Group APPT) and other indications for corticosteroid therapy (Group RPPT). A Kaplan-Meier survival analysis was performed and a p value <0.05 was considered statistically significant.
46.4% (n=97) of pregnant women gave birth in the seven days following corticosteroid administration. Delivery within 7 days occurred more frequently on group 2 in comparison to group 1 (57.3 versus42.4%; p=0.001). There is a statistically significant difference between the survival curve for groups 1 and 2, with a hazard ratio for delivery within 7 days 1.71 times higher for group 2 (95%CI 1.23-2.37; p<0.001)
It can be concluded that the probability of an event (birth within 7 days after corticosteroids) is smaller in the group of pregnant women admitted in the context of threatened preterm labor than for other indications. The use of corticosteroids in pregnant women admitted for suspected preterm labor should be subject to rigorous clinical evaluation

To validate the instrument Body Image Relationship Scale (BIRS) for Brazilian women with breast cancer
The instrument was administered by trained interviewers to 139 women who used the Brazilian Unified Health System (SUS). All of them had been submitted to cancer treatments between 2006 and 2010. The instrument was validated considering internal consistency and reliability. In order to compare the techniques, the same factorial analysis as used in the original paper was carried out
The Spearman-Brown correlation value was 0.8, indicating high internal reliability. The Cronbach's alpha found was 0.9, indicating a high level of internal consistency. Factorial analysis showed that four items had low factorial load and no discriminatory power, and another five items were relocated to other factors. When the instrument was applied, it showed variability to that of the original instrument
The Brazilian version of the Body Image Relationship Scale (BIRS), namedEscala de Relacionamento e Imagem Corporal (ERIC), showed evidence of adequate reliability and internal consistency, making this instrument suitable to be recommended for application to Brazilian women with breast cancer, despite some limitations.

To determine the prevalence of HPV-induced lesions in the anal canal of women with cervical intraepithelial neoplasia (CIN) grade 2/3.
A cross-sectional study was carried out from December 2008 to June 2009, in Pernambuco, northeastern Brazil. Only women with grade 2/3 CIN were included, and those who could not undergo anoscopy during their first visit were excluded. A cyttobrush was used for sample collection in order to identify HPV DNA through PCR and anal cytology. An anal biopsy was obtained in cases of abnormal anal cytology or major alterations in high resolution anoscopy (HRA).
Thirty-two percent (n=37/115) of HRA were normal and 63.5% (n=73/115) showed acetowhite epithelium. Twenty-two percent (n=26/115) of anal cytologies were abnormal. Among the latter, 12.2% (n=14/26) were low-grade anal intraepithelial lesions and 3.4% (n=4/26) were high-grade anal intraepithelial lesions. Twenty-two anal biopsies were performed, 13.7% of which (n=3/22) were grade 2 anal intraepithelial neoplasia (AIN2) and 9% (n=2/22) were grade 3 AIN. Th HPV DNA was identified in 72.1% of cases (n=83/115).
Women with CIN grade 2/3 showed a high prevalence of anal HPV infection and HPV-induced lesions.

To determine adherence to dual contraception using depot-medroxyprogesterone acetate (DMPA) and condom among HIV-infected women.
A cross-sectional study carried out from December 2013 to September 2014 at a local reference center, with application of questionnaire elaborated after Delphi panel and content validation to 114 HIV(+) women aged 15 to 49 years, using DMPA plus condom for contraception.
Mean age was 33.2±7.2 years, mean time since HIV detection was 8.1±5.2 years, mean time of antiretroviral use was 6.8±5 years and mean CD4 cells/mm count was 737.6±341.1. Sexual HIV acquisition was reported by 98.2% (112/114), antiretroviral use by 85.9% (98/114), and 77.7% (84/114) had a CD4>500/mm count. Having a single sex partner was reported by 78.9% (90/114), with HIV serodiscordance in 41.2% (47/114) of couples, 21.9% did not know the serological status of their partner and in 37.7% of cases (43/114) the partner was unaware of the HIV(+) status of the woman. The last pregnancy was unplanned in 71.9% of cases (82/114) and 14.9% of the women had become pregnant the year before, with pregnancy being unplanned in 70.5% (12/17) of cases. Current use of DMPA was reported by 64.9% (74/114), with genital bleeding in 48.2% (55/114) and weight gain in 67.5% (77/114). Use of a male condom was reported by 62.2% of the subjects (71/114). Three reported that they always used a female condom and ten that they eventually used it. Unprotected vaginal sex was reported by 37.7% (43/114) and unprotected anal intercourse was reported by 32.4% (37/114). Partner resistance to use a condom occurred in 30.7% of cases (35/114). Dual contraception using DMPA with condom was reported by 42.9% (49/114). A partner who resisted wearing a condom was associated with poor adhesion (PR=0.3; 95%CI 0.2-0.7; p<0.001). A partner who was unaware that a woman was infected with HIV favored adherence (PR=1.8; 95%CI 1.2-2.7; p=0.013).
The percentage of dual contraception using DMPA plus condom was 42.9%, maintaining unplanned pregnancies and unprotected sex. Resistance of partners to use a condom increased three times the chance of a woman not adhering to dual contraception, and the partner not knowing women's HIV infection almost doubled the chance to adhere to safe contraception. Goals: to offer new hormonal contraceptives and to involve the partners in contraception and serologic detection tests.
