Gestational hypertension as a factor associated with chronic kidney disease: the importance of obstetric history of women undergoing hemodialysis / Hipertensão gestacional como fator associado à doença renal crônica: a importância do histórico obstétrico de mulheres submetidas à hemodiálise

ABSTRACT Introduction: Pregnancy-related complications may impact women's reproductive cycle and health through their lives. The objective of this study was to evaluate the sociodemographic, clinical, and obstetric history of women undergoing hemodialysis. Methods: We performed a cross-sectional study in a specialized health facility with four hemodialysis units. Sociodemographic characteristics, clinical and personal history, obstetric and perinatal results of women with pregnancies before hemodialysis were evaluated. Prevalence, bivariate, and logistic regression analyses were performed. Results: We included 208 (87.76%) women. Hypertension was the main cause of chronic kidney disease (CKD) (128 women). Rates of adverse perinatal outcomes, including prematurity, low birth weight, miscarriage, fetal death, and neonatal death, were 19.3%, 14.5%, 25.5%, 12.1%, and 5.3%, respectively. Hypertensive syndromes during pregnancy occurred in 37.0% of women, with 12.5% reporting preeclampsia and 1.4% reporting eclampsia. Up to 1 year after birth, 45.2% of women reported hypertension. Hemodialysis due to hypertension was associated with a history of hypertension during pregnancy (OR 2.33, CI 1.27 - 4.24), gestational hypertension (2.41, CI 3.30 - 4.45), and hypertension up to one year after birth (OR 1.98, CI 1.11 - 3.51). Logistic regression showed that gestational hypertension was independently associated with CKD due to hypertension (aOR 2.76, CI 1.45 - 5.24). Conclusion: Women undergoing hemodialysis due to hypertension were more likely to have gestational hypertension or hypertension up to one year after birth. To delay end-stage renal disease, it is necessary to identify women at risk of kidney failure according to their reproductive history.

RESUMO Introdução: Complicações relacionadas à gestação podem afetar o ciclo reprodutivo e a saúde das mulheres ao longo de suas vidas. Este estudo visou avaliar histórico sociodemográfico, clínico e obstétrico de mulheres em hemodiálise. Métodos: Realizamos estudo transversal em unidade de saúde especializada com quatro unidades de hemodiálise. Avaliou-se características sociodemográficas, histórico clínico e pessoal, resultados obstétricos e perinatais de mulheres com gestações anteriores à hemodiálise. Foram realizadas análises de prevalência, bivariadas e regressão logística. Resultados: Incluímos 208 (87,76%) mulheres. Hipertensão foi a principal causa de doença renal crônica (DRC) (128 mulheres). Taxas de desfechos perinatais adversos, incluindo prematuridade, baixo peso ao nascer, aborto espontâneo, óbito fetal e neonatal, foram de 19,3%, 14,5%, 25,5%, 12,1% e 5,3%, respectivamente. Síndromes hipertensivas durante a gestação ocorreram em 37,0% das mulheres, com 12,5% relatando pré-eclâmpsia e 1,4% relatando eclampsia. Até 1 ano após o parto, 45,2% das mulheres relataram hipertensão. Hemodiálise devido à hipertensão foi associada ao histórico de hipertensão na gestação (OR 2,33; IC 1,27 - 4,24), hipertensão gestacional (2,41; IC 3,30 - 4,45), e hipertensão até um ano após o parto (OR 1,98; IC 1,11 - 3,51). A regressão logística mostrou que hipertensão gestacional foi independentemente associada à DRC devido à hipertensão (ORa 2,76; IC 1,45 - 5,24). Conclusão: Mulheres submetidas à hemodiálise por hipertensão foram mais propensas a apresentar hipertensão gestacional ou hipertensão até um ano após o parto. Para retardar a doença renal em estágio terminal, deve-se identificar mulheres em risco de insuficiência renal de acordo com sua história reprodutiva.

Prepregnancy overweight and obesity as risk factors for birth defects: a cross-sectional study over a 30-year period.

Overweight and obesity are public health problems worldwide despite being modifiable conditions. The association between birth defects and pregestational maternal body mass index is not entirely clear. We aimed to assess the prevalence and estimate the risk of birth defects related to pregestational body mass index and other maternal factors. We explored a 30-year time series database in a cross-section study. We analysed 40,217 cases, among them 2.8% had birth defects. Bivariate analysis showed a higher prevalence of birth defects with increased pre-pregnancy body mass index and in extremes of maternal age, white skin colour, and primiparity. Multivariable logistic regression showed a higher chance of birth defects in women with pre-pregnancy overweight/obesity (OR:1.19 [CI95%:1.01-1.41]), maternal age ≥ 40 years (OR:1.68 [CI95%:1.11-2.54]), and white skin colour (OR:1.44 [CI95%:1.19-1.75]). Maternal weight is a modifiable risk factor that must be considered and addressed in preconception counselling to minimise possible deleterious effects on embryogenesis.IMPACT STATEMENTWhat is already known on this subject? Previous studies have linked some maternal factors with birth defects. However, the association with prepregnancy maternal body mass index is not clear.What do the results of this study add? Our findings provide support for the association of prepregnancy maternal overweight and obesity with birth defects and highlight that BMI is a modified risk factor.What are the implications of these findings for clinical practice and/or further research? Maternal body mass index is a modifiable risk factor, highlighting the importance of preconception counselling for the prevention and possible reduction of factors that increase the risk of birth defects.

Circulating Plasma miRNA and Clinical/Hemodynamic Characteristics Provide Additional Predictive Information About Acute Pulmonary Thromboembolism, Chronic Thromboembolic Pulmonary Hypertension and Idiopathic Pulmonary Hypertension.

Idiopathic pulmonary artery hypertension (IPAH), chronic thromboembolic pulmonary hypertension (CTEPH), and acute pulmonary embolism (APTE) are life-threatening cardiopulmonary diseases without specific surgical or medical treatment. Although APTE, CTEPH and IPAH are different pulmonary vascular diseases in terms of clinical presentation, prevalence, pathophysiology and prognosis, the identification of their circulating microRNA (miRNAs) might help in recognizing differences in their outcome evolution and clinical forms. The aim of this study was to describe the APTE, CTEPH, and IPAH-associated miRNAs and to predict their target genes. The target genes of the key differentially expressed miRNAs were analyzed, and functional enrichment analyses were carried out. The miRNAs were detected using RT-PCR. Finally, we incorporated plasma circulating miRNAs in baseline and clinical characteristics of the patients to detect differences between APTE and CTEPH in time of evolution, and differences between CTEPH and IPAH in diseases form. We found five top circulating plasma miRNAs in common with APTE, CTEPH and IPAH assembled in one conglomerate. Among them, miR-let-7i-5p expression was upregulated in APTE and IPAH, while miRNA-320a was upregulated in CTEP and IPAH. The network construction for target genes showed 11 genes regulated by let-7i-5p and 20 genes regulated by miR-320a, all of them regulators of pulmonary arterial adventitial fibroblasts, pulmonary artery endothelial cell, and pulmonary artery smooth muscle cells. AR (androgen receptor), a target gene of hsa-let-7i-5p and has-miR-320a, was enriched in pathways in cancer, whereas PRKCA (Protein Kinase C Alpha), also a target gene of hsa-let-7i-5p and has-miR-320a, was enriched in KEGG pathways, such as pathways in cancer, glioma, and PI3K-Akt signaling pathway. We inferred that CTEPH might be the consequence of abnormal remodeling in APTE, while unbalance between the hyperproliferative and apoptosis-resistant phenotype of pulmonary arterial adventitial fibroblasts, pulmonary artery endothelial cell and pulmonary artery smooth muscle cells in pulmonary artery confer differences in IPAH and CTEPH diseases form. We concluded that the incorporation of plasma circulating let-7i-5p and miRNA-320a in baseline and clinical characteristics of the patients reinforces differences between APTE and CTEPH in outcome evolution, as well as differences between CTEPH and IPAH in diseases form.

Putting knowledge into practice-the challenge of acquiring healthy habits during pregnancy colocando conhecimento em prática - o desafio de adquirir hábitos saudáveis durante a gravidez

Abstract Objective The aim of this study was to investigate the knowledge concerning gestational weight gain (GWG), nutrition, and physical exercise (PE) in pregnant women, and how to put them into practice. Methods A cross-sectional study with 61 pregnant women above 26 weeks of gestation, at the Woman's Hospital, CAISM, University of Campinas. Questionnaires regarding the knowledge of healthy habits (HH) during pregnancy, sociodemographic data, and previous obstetric outcomes were applied. An educational guide with advice on HH during pregnancy and in the postpartum period was offered. Results The average age of women was 28.7 ± 6.23 years, with 85% of them being married; 32% nulliparous; the average body mass index (BMI) before pregnancy was 25.4 ± 9.8 kg/m2, and themean number of years of schoolingwas 11.2 ± 3.8. Only 61%of the subjects had received any previous information about GWG during their antenatal care and were aware as to howmany pounds they should gain during pregnancy. Among the 61 women, 85% understood that they did not need to "eat for 2" and 99% knew that PE had benefits for their body and was safe for their baby. Half of the women practiced PE prior to pregnancy; however, only 31% continued the practice of PE during the pregnancy. Conclusion Despite understanding the need for HH during pregnancy, women still need encouragement to practice PE during pregnancy, as well as more information about GWG.

Shock index and heart rate standard reference values in the immediate postpartum period: A cohort study.

OBJECTIVE: To determine Shock Index (SI) reference values in the first two hours of the postpartum period after objectively measuring postpartum bleeding. MATERIALS AND METHODS: A complementary analysis using data from a prospective cohort study at Women's Hospital of the University of Campinas, Brazil, between 1 February 2015 and 31 March 2016. It included women giving birth vaginally unless they had one of these conditions: gestational age below 34 weeks, hypertension, hypo- or hyperthyroidism without treatment, any cardiac disease, infections with fever or sepsis, history of coagulopathy or delivery by C-section. Blood loss was measured by adding the blood volume collected in the drape placed under the women's buttocks and the weight of gauzes and compresses used (excluding the dry weight). Vital signs were measured every 5-15 min after delivery. Exploratory data analysis was performed to assess the mean, standard deviation, median, and percentiles (5th, 10th, 25th, 50th, 75th, 90th, 95th). To identify variation among the periods after delivery, the mean SI and heart rate (HR) values observed for the following intervals were used in the analysis: 0-20 min, 21-40 min, 41-60 min, 61-90 min and 91-120 min. RESULTS: One hundred eighty-six women were included. The mean age ± SD was 24.9 ± 6.1 years and the mean gestational age at birth was 39.2 ± 1.8 weeks. At the puerperal period, the mean SI values ranged from 0.68 ± 0.14 to 0.74 ± 0.15. The percentile distribution ranged from 0.46 (5th percentile) to 1.05 (95th percentile). The mean HR values ranged from 80.8 ± 12.7 bpm to 92.3 ± 14.4 bpm. The percentile distribution ranged from 62.0 bpm (5th percentile) to 117 bpm (95th percentile). CONCLUSION: Reference ranges were established for SI and HR values which showed small variations throughout the postpartum period.

How to classify BMI among pregnant adolescents? A prospective cohort.

OBJECTIVE: Pregnancy in adolescence is a global health issue, especially in developing countries. Additionally, the recommended gestational weight gain (GWG) is usually based on pre-pregnancy BMI and that might be complex for pregnant teens. The study objective was to compare three different methods of BMI classification and suggest the best way of determining pre-pregnancy BMI and monitoring GWG among pregnant adolescents. DESIGN: Pre-pregnancy weight, weight at first prenatal visit, height, sociodemographic, reproductive and perinatal data were collected. Weighted kappa and McNemar statistics were used to assess agreement between the classification methods. SETTING: Prof. Dr Jose Aristodemo Pinotti Women's Hospital, University of Campinas, Brazil.ParticipantsPrimiparas younger than 19 years of age and with less than 20 weeks of gestational age (n 150). RESULTS: BMI of the primiparas was determined according to the WHO recommendation for adult women, the Child Growth Standards (CGS) and their gynaecological age (GA). The WHO and GA measurements presented a strong agreement with each other (κ w=0·99; 95 % CI 0·97, 1·00), but did not agree with the CGS classification (κ w=0·62; 95 % CI 0·50, 0·74 by WHO; κ w=0·62; 95 % CI 0·51, 0·74 by GA). Also, inadequate GWG was observed in 72·2 % of cases and was correlated with a higher rate of caesarean birth. CONCLUSIONS: BMI classification according to the CGS differed from WHO and GA. However, CGS and WHO agreed on perinatal outcomes. We recommend using BMI classification by WHO to assess pregnant adolescents, since it is easily applied and better known among health professionals.

Body mass Index changes during pregnancy and perinatal outcomes - A cross-sectional study / Mudanças do índice de massa corporal na gravidez e resultados perinatais - um estudo transversal

Abstract Objective To evaluate the relation between changes the body mass index (BMI) percentile, reflected in the Atalah curve, and perinatal outcomes. Methods A cross-sectional study with 1,279 women was performed. Data regarding gestational weight, sociodemographic characteristics and perinatal outcomes were collected through medical charts, prenatal card and interviews in the postpartum period. Women could be classified according to the Atalah curve in the following categories: low weight, adequateweight, overweight, and obese. The BMIwas calculated at the first and at the last prenatal care visits, and these values were compared. Results An increase in the BMI category according to the Atalah classification occurred in 19.9% of pregnant women, and an increase of 3.4, 5.8 and 6.4 points of BMI were found for women respectively classified in the adequate weight, overweight and obese categories at the first prenatal visit. Women with high school education presented a lower chance of increasing their BMI (odds ratio [OR] 0:47 [0.24- 0.95]). Women who evolved with an increase in the the Atalah classification were associated with cesarean section (OR 1.97-2.28), fetalmacrosomia (OR 4.13-12.54) and large for gestational age newborn (OR 2.88-9.83). Conclusion Pregnant women who gained enough weight to move up in their BMI classification according to the Atalah curve had a higher chance of cesarean section and macrosomia. Women classified as obese, according to the Atalah curve, at the first prenatal visit had a high chance of cesarean section and delivering a large for gestational age newborn.

A novel body mass index reference range - an observational study.

OBJECTIVE: To generate a new body mass index curve of reference values and ranges for body mass index and weight gain during pregnancy and to compare the new curve and weight gain ranges with the currently used references. METHODS: A prospective observational study was conducted with a total of 5,656 weight and body mass index measurements in 641 women with single pregnancy who attended their first prenatal visit before 12 weeks. All the women were over 18 years old and had no medical conditions that would influence body mass index. Data were collected using prenatal charts and medical records during hospitalization for childbirth. A linear regression method was used for standard curve smoothing in the general population and for specific curves according to the baseline body mass index classification. Curves were obtained for the 5th, 10th, 50th, 85th, 90th and 95th percentiles. Concordance between the classification of women using the newly generated and currently used curves was evaluated by percentages and kappa coefficients. The weight gain was compared with the reference values of the Institute of Medicine using Student's T test. The data were analyzed using SAS software version 9.2, and the significance level was set at 5%. RESULTS: A general reference curve of percentiles of body mass index by gestational age was established. Additionally, four specific curves were generated according to the four baseline body mass index categories. The new general curve offered percentile limits for women according to their initial body mass index and according to the Centers for Disease Control and Prevention limits, showing poor agreement with the currently used curve (48.3%). Women who were overweight or obese when starting prenatal care had higher weight gain than the Institute of Medicine recommendation. CONCLUSIONS: The new proposed curve for body mass index during pregnancy showed weak agreement with the currently used curve. The new curve provided more information regarding body mass index increase using percentiles for general and specific groups of body mass index. Overweight pregnant women showed an upward body mass index trend throughout pregnancy that increased more dramatically than those of other groups of pregnant women, and they also presented a major mean difference between weight gain and the Institute of Medicine recommendation.

Fetal growth standards in gastroschisis: Reference values for ultrasound measurements.

OBJECTIVES: The objectives of this study were to create growth curves based on ultrasonography biometric parameters of fetuses with gastroschisis, comparing them with normal growth standards, and to analyze umbilical artery (UA) Doppler velocimetry patterns. METHODS: A cohort study of 72 fetuses with gastroschisis, at gestational ages between 14 and 39 weeks was designed. Mean and standard deviation were calculated, with the 5th, 10th, 50th, 90th, and 95th centiles being established for biometric parameters according to gestational age. Curves were obtained, comparing with normal reference via the Mann-Whitney test. UA Doppler velocimetry patterns were obtained. RESULTS: A total of 434 examinations were performed, and centiles were established for biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight. A significant difference was observed between the gastroschisis measurements when compared to control, with all curves shifted downwards. Abdominal circumference was the parameter presenting the largest difference. Estimated fetal weight was also lower, with mean difference of 256.3 ± 166.8 g for the 50th centile (P < .0001). UA Doppler velocimetry was normal in 97.5%. CONCLUSIONS: Fetuses with gastroschisis show symmetrical growth deficits in the second and third trimesters, with normal UA Doppler velocimetry. These results reinforce the hypothesis that they are constitutionally smaller, yet not restricted because of placental insufficiency.

Demora no diagnóstico de câncer de mama de mulheres atendidas no Sistema Público de Saúde / Delay in breast cancer diagnosis on women assisted in the Public Health System

Resumo Introdução Apesar dos esforços, a mortalidade por câncer de mama se mantém elevada no Brasil e é mais frequente em regiões em que o acesso aos serviços de saúde é dificultado ou inexistente. Uma das recomendações do Instituto Nacional do Câncer (INCA) para reduzir a mortalidade é melhorar o acesso ao diagnóstico, realizando-o em até 60 dias após a suspeita. Objetivo Estabelecer o tempo decorrido (em dias) entre a suspeita e o diagnóstico do câncer de mama, subdividindo os intervalos entre os eventos: consulta médica na atenção básica; mamografia ou ultrassonografia; consulta médica especializada; biópsia; consulta médica para conclusão do diagnóstico. Métodos Estudo descritivo e seccional, realizado com 45 mulheres atendidas em um serviço público de saúde, com diagnóstico de câncer de mama efetivado em 2013. Resultados A média da demora foi de 142,6 ± 10,1 dias (12-451), com 60% dos diagnósticos efetivados entre 120 e 180 dias, e chance de efetivação do diagnóstico em até 60 dias para 8,9% da amostra. Conclusão Há necessidade de implementação efetiva das linhas de cuidado na rede de atenção oncológica, com pactuação dos fluxos entre os serviços para agilizar o acesso à assistência integral às mulheres.

Abstract Introduction Despite efforts, mortality from breast cancer remains high in Brazil and is most common in regions where access to health services is difficult or inexistent. One of the INCA’s (Instituto Nacional do Câncer) recommendations to reduce mortality is to improve the early diagnosis for up to 60 days after the suspicious. Objective To establish the elapsed time (in days) between the suspect and the breast cancer diagnosis, subgrouping the timeframe in the events of: primary care medical appointment; mammography and/or ultrasonography; specialized medical appointment; biopsy and; medical appointment for the diagnosis conclusion. Methods The descriptive and sectional study was accomplished with samples from 45 women attending the public health service, diagnosed with breast cancer in 2013. Results The average elapsed time was of 142.6 days ± 10.1 (12-451), with 60% of diagnosis performed within 120 and 180 days and effective diagnosed chance of up to 60 days for 8.9% of the cases. Conclusions A effective implementation of care lines in the cancer care network is in need, with connection between services to speed women access to comprehensive assistance.

Association between parity, pre-pregnancy body mass index and gestational weight gain.

OBJECTIVE: To analyze the relationship between parity, pre-pregnancy body mass index (BMI), and gestational weight gain (GWG). METHODS: This observational controlled study was conducted from November 2013 to April 2014, with postpartum women who started antenatal care up to 14 weeks and had full-term births. Data were collected from medical records and antenatal cards. Descriptive and bivariate analyses were performed. The significance level was 5%. RESULTS: Data were collected from 130 primiparous and 160 multiparous women. At the beginning of prenatal care, 54.62% of the primiparous were eutrophic, while the majority of multiparous were overweight or obese (62.51%). Multiparas are two times more likely to be obese at the beginning of their pregnancies, when compared to primiparas. The average pre-pregnancy weight and final pregnancy weight was significantly higher in multiparous, however, the mean GWG was higher among primiparous. CONCLUSION: We found an inverse correlation between parity and the total GWG, but initial BMI was significantly higher in multiparas. Nevertheless, monitoring of the GWG through actions that promote a healthier lifestyle is needed, regardless of parity and nutritional status, in order to prevent excessive GWG and postpartum weight retention and consequently inadequate pre-pregnancy nutritional status in future pregnancies.

Physical Activity Patterns and Factors Related to Exercise during Pregnancy: A Cross Sectional Study.

OBJECTIVE: To assess the physical activity levels of pregnant women and to examine the characteristics associated with the practice of exercise and the activities of daily living during pregnancy. METHODS: For this cross-sectional study, 1,279 women were recruited within 72 hours postpartum. They were interviewed about their socio-demographic data and obstetric history and were administered self-report questionnaires about exercise and daily physical activities during pregnancy. Data on the current pregnancy, labor, delivery, and newborn outcomes were collected from participants' medical records. To analyze factors related to the practice of exercise, we used the student t-test, X², and odds ratio (OR), with a corresponding 95% confident interval (CI), followed by a multiple logistic regression. The significance level was 5%. RESULTS: Compared to the pre-pregnancy period, the prevalence of physical activity among participants was lower throughout pregnancy (20.1%) (p = 0.01). Half of the women interrupted practicing physical exercise due to pregnancy. The lowest prevalence of exercise was observed in the first (13.6%) and third trimesters (13.4%). Less than half of women received exercise guidance during prenatal care meetings (47.4%). Walking was the most commonly reported exercise, followed by water aerobics. Factors positively associated with exercise practice were higher educational level (OR= 1.82; CI 95% 1.28-2.60), primiparity (OR=1.49; CI 95% 1.07-2.07), exercising before pregnancy (OR= 6.45; CI 95% 4.64-8.96), and exercise guidance during prenatal care (OR=2.54; CI 95% 1.80-3.57). Mildly intense exercise and domestic activities were most frequently reported among pregnant women. There were no differences in maternal and perinatal outcomes between active and sedentary pregnant women. CONCLUSION: The findings indicate that promoting physical activity remains a priority in public health policy, and women of childbearing age, especially those planning a pregnancy, should be encouraged to adopt an exercise routine or maintain an active lifestyle during pregnancy in order to avoid sedentary- and obesity-associated risks.

Short-term physical therapy treatment for female urinary incontinence: a quality of life evaluation.

INTRODUCTION: Urinary incontinence (UI) is a widespread health condition and in some situations conservative treatment has been recommended. The aim of this study was to compare women's quality of life (QoL) before and after short-term physical therapy treatment. METHODS: We carried out a clinical trial involving 72 women who received an eight-session intervention based on pelvic floor electrical stimulation (PFES), pelvic floor muscle training (PFMT) and behavioral training. QoL was evaluated by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). The Wilcoxon signed-rank test compared the ICIQ-SF scores; the relative changes were calculated by dividing the differences by the initial score, and McNemar's χ(2) compared the questions related to the type of, possible causes of or situations related to UI (p < 0.05). RESULTS: There was a significant reduction in the frequency (p < 0.03), amount (p < 0.04) and impact (p < 0.001) of UI on QoL. The total score decreased from 14.6 ± 4.2 to 7.2 ± 4.5 (p < 0.001). All questions regarding the type of, possible causes of or situations related to UI had significantly decreased. Also, 15 women reported the 'never leaked urine' condition (p < 0.001) after treatment. CONCLUSION: A short-term physical therapy treatment based on PFES, PFMT and behavioral modifications reduced the frequency, amount and impact of UI and therefore resulted in QoL improvement.
