Abstract Objective The lack of data on the impact of hyperglycemia and obesity on the prevalence of pregnancy-specific urinary incontinence (PSUI) led us to conduct a cross-sectional study on the prevalence and characteristics of PSUI using validated questionnaires and clinical data. Methods This cross-sectional study included 539 women with a gestational age of 34 weeks who visited a tertiary university hospital between 2015 and 2018. The main outcome measures were the prevalence of PSUI, the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Incontinence Severity Index (ISI) questionnaires. The women were classified into four groups: normoglycemic lean, normoglycemic obese, hyperglycemic lean, and hyperglycemic obese. The differences between groups were tested using descriptive statistics. Associations were estimated using logistic regression analysis and presented as unadjusted and adjusted odds ratios. Results Prevalence rates of PSUI were no different between groups. However, significant difference in hyperglycemic groups worse scores for severe and very severe PSUI. When adjusted data for confound factors was compared with normoglycemic lean group, the hyperglycemic obese group had significantly higher odds for severe and very severe forms of UI using ICIQ-SF (aOR 3.157; 95% CI 1.308 to 7.263) and ISI (aOR 20.324; 95% CI 2.265 to 182.329) questionnaires and highest perceived impact of PSUI (aOR 4.449; 95% CI 1.591 to 12.442). Conclusion Our data indicate that obesity and hyperglycemia during pregnancy significantly increase the odds of severe forms and perceived impact of PSUI. Therefore, further effective preventive and curative treatments are greatly needed.

Resumo Objetivo A falta de dados sobre o impacto da hiperglicemia e obesidade na prevalência de incontinência urinária específica da gravidez (IAPS) nos levou a realizar um estudo transversal sobre a prevalência e características da IAPS usando questionários validados e dados clínicos. Métodos Este estudo transversal incluiu 539 mulheres com idade gestacional de 34 semanas que visitaram um hospital universitário terciário entre 2015 e 2018. As principais medidas de desfecho foram a prevalência de PSUI, o formulário curto do International Consultation on Incontinence Questionnaire (ICIQ-SF) e os questionários do Incontinence Severity Index (ISI). As mulheres foram classificadas em quatro grupos: magras normoglicêmicas, obesas normoglicêmicas, magras hiperglicêmicas e obesas hiperglicêmicas. As diferenças entre os grupos foram testadas por meio de estatística descritiva. As associações foram estimadas usando análise de regressão logística e apresentadas como odds ratio não ajustadas e ajustadas. Resultados As taxas de prevalência de PSUI não foram diferentes entre os grupos. No entanto, houve diferença significativa nos grupos hiperglicêmicos com piores escores para PSUI grave e muito grave. Quando os dados ajustados para fatores de confusão foram comparados ao grupo magro normoglicêmico, o grupo obeso hiperglicêmico teve chances significativamente maiores de formas graves e muito graves de IU usando ICIQ-SF (aOR 3,157; IC 95% 1,308 a 7,263) e ISI (aOR 20,324; 95% CI 2,265 a 182,329) questionários e maior impacto percebido de PSUI (aOR 4,449; 95% CI 1,591 a 12,442). Conclusão Nossos dados indicam que a obesidade e a hiperglicemia durante a gravidez aumentam significativamente as chances de formas graves e o impacto percebido da PSUI. Portanto, tratamentos preventivos e curativos mais eficazes são extremamente necessários.

There is an ongoing discussion regarding abdominal muscle (AbM) and pelvic floor muscle (PFM) synergism. Therefore, this study aimed to investigate the cocontraction between AbMs and PFMs in women with or without pelvic floor dysfunction (PFD). The following databases were searched up to December 21, 2018: MEDLINE, EMBASE, LILACS, PEDro and CENTRAL. We included any study that assessed the cocontraction between PFMs and AbMs in women with and without PFD. Two reviewers independently screened eligible articles and extracted data. The outcomes were extracted and analyzed as continuous variables with random effect models. Twenty studies were included. A meta-analysis did not show differences in women with and without PFD. However, a sensitivity analysis suggested cocontraction of the transversus abdominis (TrA) during PFM contraction in healthy women (standardized mean difference (SMD) –1.02 [95% confidence interval (CI) −1.90 to −0.14], P=0.02; I2= not applicable; very low quality of evidence). Women with PFD during contraction of PFMs showed cocontraction of the obliquus internus (OI) (SMD 1.10 [95% CI 0.27 to 1.94], P=0.01; I2= not applicable; very low quality of evidence), and obliquus externus (OE) (SMD 2.08 [95% CI 1.10 to 3.06], P<0.0001; I2 = not applicable; very low quality of evidence). Increased cocontraction of the TrA may be associated with maximal contraction of PFMs in women without PFD. On the other hand, there is likely an increased cocontraction with the OI and OE in women with PFD.

ABSTRACT PURPOSE: To evaluate the contamination index of metals and pesticides in pregnant women, and to relate this to perinatal outcomes. METHODS: Descriptive, retrospective, exploratory study, developed from existing secondary data analyses at Level III maternity center. A total of 40 mothers with their newborns (NB), living in a rural area in Botucatu- Brazil and surrounding region. Blood samples from mothers and newborn were collected to determine the total contamination index for metals and pesticides. The concentrations of each metal and each pesticide were determined in blood samples of mothers and their newborns by Rudge's results. After obtaining these concentrations, the total contamination index in mother and NB was calculated, along with its correlation with clinical parameters of NB. RESULTS: There was no correlation (p> 0.05) between maternal contamination index with NB clinical parameters, and NB contamination index versus NB clinical parameters. CONCLUSION: The maternal contamination index of metals and pesticides was not related to perinatal outcomes, but it could be used as baseline parameter in future toxicological studies, regarding to long-term toxic characteristics as persistent organic pollutants, its long half-lives, bioacumulative, and expected to impose serious health effects on humans.
