Impact of Obesity and Hyperglycemia on Pregnancy-specific Urinary Incontinence.

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.

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.

Diastasis recti abdominis and pelvic floor dysfunction in peri- and postmenopausal women: a cross-sectional study.

INTRODUCTION: Diastasis recti abdominis (DRA) and pelvic floor dysfunction (PFD) occurs commonly with aging; however, little is known about what leads to these changes. OBJECTIVE: We aimed to investigate and compare the presence or absence of DRA and PFD in peri- and postmenopausal women. METHODS: This cross-sectional study involved 150 participants who answered questions on their sociodemographic and clinical profiles related to urinary and fecal incontinence and pelvic organ prolapse. Diastasis recti abdominis was diagnosed with a digital caliper. RESULTS: Supra-umbilical diastasis occurred in 37.3% of cases, and 78.6% of participants with DRA had PFD. No significant differences existed between participants with and without DRA in terms of background and clinical variables. However, participants with DRA were 2.6 times more likely to have PFD than participants without DRA. Furthermore, the presence of DRA was significantly shown to be a risk factor for PFD on binary logistic regression analyses (p = .01, OR = 3.2). CONCLUSIONS: This cross-sectional study suggests that DRA is a predictive factor of PFD in women aged over 50 years.

Associação da função do assoalho pélvico e mobilidade em idosas / Association of Pelvic Floor Function And Mobility In Elderly Women

Introdução: O envelhecimento populacional cresce a cada ano e, consequentemente, surgem adaptações fisiológicas do organismo, tais como: diminuição da velocidade da marcha, da estabilidade e da adaptação postural, além da perda da integralidade muscular; podendo levar a várias alterações, dentre elas: disfunções do assoalho pélvico e prejuízo na mobilidade. Objetivo: associar a função do assoalho pélvico à mobilidade em idosas. Materiais e métodos: trata-se de um estudo transversal, desenvolvido com mulheres acima de 60 anos, residentes na cidade de Bauru/SP. O estudo foi aprovado pelo Comitê de Ética em Pesquisa (parecer nº4.040.883), e todas as voluntárias, que assinaram o Termo de Consentimento Livre e Esclarecido, responderam aos questionários para caracterização sociodemográfica e verificação das queixas de disfunções do assoalho pélvico. A avaliação da mobilidade foi realizada pela marcha, por meio de uma passarela de 14 metros e da análise dos parâmetros cinemáticos da marcha pelo módulo de aquisição de sinais biológicos, com um acelerômetro triaxial posicionado sobre o maléolo lateral e uma bateria de avaliação Short Physical Performance Battery (SPPB). Resultados: No total, foram avaliadas 13 mulheres (7 no grupo com disfunção do assoalho pélvico e 6 no grupo controle), com média de idade de 64 ± 6,3 anos. As disfunções do assoalho pélvico relatadas foram: 54% de incontinência urinária, 8% de prolapsos de órgãos pélvicos, 15% de incontinência fecal e 8% de disfunção sexual. Nos resultados do SPPB, 92% das voluntárias apresentaram boa capacidade; 8%, baixa capacidade. Na avaliação da marcha, não foram encontradas diferenças estatísticas entre os grupos (p=0,260). Conclusão: Não houve relação entre as funções do assoalho pélvico e a mobilidade nas participantes avaliadas.

Introduction: Population aging grows every year and, consequently, there are physiological adaptations of the organism such as a decrease in gait speed, stability, and postural adaptation, in addition to a loss of muscle integrality, which can lead to several changes, including pelvic floor dysfunctions and impaired mobility. Objective: to associate pelvic floor function with mobility in elderly women. Materials and methods: this cross-sectional study consisted of women over 60 from the city of Bauru /SP. The Research Ethics Committee (number 4.040.883) approved the study, and all volunteers signed the Informed Consent Form and responded to questionnaires for sociodemographic characterization and verification of complaints of pelvic floor dysfunction. Mobility assessment was performed by gait using the 14-meter walkway and analysis of the kinematic parameters using the biological signal acquisition module and a triaxial accelerometer positioned on the lateral malleolus and the evaluation battery Short Physical Performance Battery. Results: A total of 13 women were evaluated (7 in the group with pelvic dysfunction and 6 in the control group) with a mean age of 64± 6,3 years. 54% of women reported urinary incontinence, 8% prolapse, 15% fecal incontinence and 8% sexual dysfunction. In the results of the SPPB, 92% of the volunteers had good ability, and 8% had low ability. In the gait assessment, there were no statistical statistics between the groups (p = 0.260). Conclusion: There was no relation between pelvic floor function and mobility in the evaluated participants.

Evaluation of satisfaction of pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence: A randomized, single-blinded clinical trial.

OBJECTIVES: To compare the satisfaction degree and pelvic floor manometry after pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence (MUI). STUDY DESIGN: A randomized, single-blinded clinical trial was conducted. 24 women diagnosed with MUI were equally divided into two groups: pelvic floor muscle training isolated and associated to transcutaneous tibial nerve stimulation (TTNS). The study occurred in four stages: 1) evaluation: general information, pelvic floor manometry, the International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and International Consultation on Incontinence Questionnaire - Overactive Bladder (OAB) application; 2) intervention: carried out over 2 months twice a week; 3) post-intervention evaluation: vaginal manometry, reapplication of the questionnaires and the Patient Global Impression (PGI) application at the end of the 2-month intervention; and, 4) follow-up: evaluation after 1 month of the end of the intervention. The primary outcome was the ICIQ-UI-SF and the secondary outcomes were ICIQ-OAB, vaginal manometry, and PGI. The repeated measures ANOVA was used to assess the time-to-group interaction by assigning a significance level of 5%. RESULTS: There was no interaction between time and group for ICIQ-UI-SF (p = 0.17) and manometry (p = 0.56). There was interaction for ICIQ-OAB (p < 0.01). PGI was reported as "much better" with 41.67% in the PFMTG + TTNS and 16.67% in the PFMTG after the intervention (p = 0.04). CONCLUSIONS: The results showed weak evidence that TTNS, in combination with PFMT, may be an intervention that can be used to treat MUI. The satisfaction degree was better with associated intervention.

Deleterious effects of gestational diabetes mellitus on the characteristics of the rectus abdominis muscle associated with pregnancy-specific urinary incontinence.

AIMS: To evaluate the effects of gestational diabetes mellitus (GDM) on the structural characteristics of the rectus abdominis muscle (RAM) and its indirect effects on pregnancy-specific urinary incontinence (PSUI). METHODS: A total of 92 pregnant women were divided into four groups, according to their clinical conditions: non-GDM continent, non-GDM associated PSUI, GDM continent and GDM associated PSUI. The muscle morphometry (histochemistry and immunohistochemistry) for the fiber types and collagen fiber distribution, the ultrastructural analysis (transmission electron microscopy), the protein expression of fiber types and calcium signaling (Western blotting), and the content of types I and III collagen fiber (ELISA) in RAM collected at delivery were assessed. RESULTS: The GDM groups presented a significantly increased number of slow fibers and slow-twitch oxidative fiber expression; decreased fiber area, number of fast fibers, and area of collagen; an increase in central nuclei; ultrastructural alterations with focal lesion areas such as myeloid structures, sarcomere disorganization, and mitochondrial alteration. The PSUI groups presented a considerable decrease in types I and III collagen contents and the localization of collagen fiber. CONCLUSIONS: Our data reveal that GDM causes morphological, biochemical and physiological changes in the RAM, and this might predispose women to PSUI.

Pregnancy-specific urinary incontinence in women with gestational hyperglycaemia worsens the occurrence and severity of urinary incontinence and quality of life over the first year post partum.

OBJECTIVE: To determine the occurrence and severity of pregnancy-specific urinary incontinence (PSUI) in women with gestational hyperglycaemia, and its impact on quality of life (QoL) over the first year post partum. STUDY DESIGN: Three hundred and eighty-eight pregnant women with PSUI were distributed into two groups (normoglycaemic and hyperglycaemic) and analysed at five timepoints during pregnancy and the first year post partum. Gestational hyperglycaemia was defined according to the criteria of the American Diabetes Association and the glucose profile test. Relationships with outcome were analysed using Chi-squared test for categorical variables and Student's t-test for quantitative variables. RESULTS: The overall prevalence rate of PSUI was 54.1 %, with prevalence rates of 43.3 % and 56.7 % in normoglycaemic and hyperglycaemic Brazilian pregnant women, respectively. Women with gestational hyperglycaemia had a higher amount of urine loss (p < 0.0027), frequency of UI (p < 0.0014), impact of UI on QoL (p < 0.0001), severity of UI (p = 0.0003) and total scores on the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-SF) and Incontinence Severity Index (ISI) (p<0.0001) at the two timepoints during pregnancy; and a higher amount of urine loss (p = 0.0079), frequency of UI (p = 0.0382), impact of UI on QoL (p < 0.0001), severity of UI (p = 0.0053) and questionnaire scores (p < 0.0001 for ICIQ-SF and p = 0.003 for ISI) over the first year post partum. CONCLUSIONS: PSUI in women with gestational hyperglycaemia worsens the occurrence and severity of UI, and the impact of UI on QoL over the first year post partum. These results emphasize the interaction between PSUI, gestational hyperglycaemia and long-term maternal outcome.

Alterations in the structural characteristics of rectus abdominis muscles caused by diabetes and pregnancy: A comparative study of the rat model and women.

BACKGROUND AND OBJECTIVE: In the present study, we compared the effect of diabetic pregnancy on the rectus abdominis muscle (RAM) in humans and rats. We hypothesized that our animal model could provide valuable information about alterations in the RAM of women with Gestational Diabetes (GDM). METHOD: Newborns female rats (n = 10/group) were administered streptozotocin (100 mg/kg body weight) subcutaneously and were mated on reaching adulthood, to develop the mild hyperglycemic pregnant (MHP) rat model. At the end of pregnancy, the mothers were sacrificed, and the RAM tissue was collected. Pregnant women without GDM (non-GDM group; n = 10) and those diagnosed with GDM (GDM group; n = 8) and undergoing treatment were recruited, and RAM samples were obtained at C-section. The RAM architecture and the distribution of the fast and slow fibers and collagen were studied by immunohistochemistry. RESULTS: No statistically significant differences in the maternal and fetal characters were observed between the groups in both rats and women. However, significant changes in RAM architecture were observed. Diabetes in pregnancy increased the abundance of slow fibers and decreased fast fiber number and area in both rats and women. A decrease in collagen distribution was observed in GDM women; however, a similar change was not observed in the MHP rats. CONCLUSION: Our results indicated that pregnancy- associated diabetes- induced similar structural adaptations in the RAM of women and rats with slight alterations in fiber type number and area. These findings suggest that the MHP rat model can be used for studying the effects of pregnancy-associated diabetes on the fiber structure of RAM.

Study protocol to investigate biomolecular muscle profile as predictors of long-term urinary incontinence in women with gestational diabetes mellitus.

BACKGROUND: Pelvic floor muscles (PFM) and rectus abdominis muscles (RAM) of pregnant diabetic rats exhibit atrophy, co-localization of fast and slow fibers and an increased collagen type I/III ratio. However, the role of similar PFM or RAM hyperglycemic-related myopathy in women with gestational diabetes mellitus (GDM) remains poorly investigated. This study aims to assess the frequency of pelvic floor muscle disorders and pregnancy-specific urinary incontinence (PS-UI) 12 months after the Cesarean (C) section in women with GDM. Specifically, differences in PFM/RAM hyperglycemic myopathy will be evaluated. METHODS: The Diamater is an ongoing cohort study of four groups of 59 pregnant women each from the Perinatal Diabetes Research Centre (PDRC), Botucatu Medical School (FMB)-UNESP (São Paulo State University), Brazil. Diagnosis of GDM and PS-UI will be made at 24-26 weeks, with a follow-up at 34-38 weeks of gestation. Inclusion in the study will occur at the time of C-section, and patients will be followed at 24-48 h, 6 weeks and 6 and 12 months postpartum. Study groups will be classified as (1) GDM plus PS-UI; (2) GDM without PS-UI; (3) Non-GDM plus PS-UI; and (4) Non-GDM without PS-UI. We will analyze relationships between GDM, PS-UI and hyperglycemic myopathy at 12 months after C-section. The mediator variables to be evaluated include digital palpation, vaginal squeeze pressure, 3D pelvic floor ultrasound, and 3D RAM ultrasound. RAM samples obtained during C-section will be analyzed for ex-vivo contractility, morphological, molecular and OMICS profiles to further characterize the hyperglycemic myopathy. Additional variables to be evaluated include maternal age, socioeconomic status, educational level, ethnicity, body mass index, weight gain during pregnancy, quality of glycemic control and insulin therapy. DISCUSSION: To our knowledge, this will be the first study to provide data on the prevalence of PS-UI and RAM and PFM physical and biomolecular muscle profiles after C-section in mothers with GDM. The longitudinal design allows for the assessment of cause-effect relationships between GDM, PS-UI, and PFMs and RAMs myopathy. The findings may reveal previously undetermined consequences of GDM.

Validation of the international consultation on incontinence modular questionnaire - female lower urinary tract symptoms (ICIQ-FLUTS) into brazilian portuguese

ABSTRACT Purpose: To translate, adapt and validate the International Consultation on Incontinence Modular Questionnaire on Female Lower Urinary Tract Symptoms ICIQ-FLUTS for the Brazilian female population. Materials and Methods: A translation of the questionnaire into Brazilian Portuguese was made followed by an adaptation for better understanding by native speakers. After that, the ICIQ-FLUTS was answered by eighty volunteers (n=80) twice (for interviewers 1 and 2) with an interval of 30 minutes between them. Furthermore, after 15 days from the evaluation, the participants answered the ICIQ-FLUTS again in order to verify the questionnaire stability over time. The questionnaires Utian Quality Of Life (UQOL) and International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), which are validated in Brazil were also applied to perform the validation. Results: The result of the Cronbach α coefficient of the instrument presented a value of 0.832. The values for test-retest were 0.907 (inter-observer) and 0.901 (intra-observer). The correlation between ICIQ-FLUTS (score I - domain of urinary incontinence) with the ICIQ-SF (final score) was strong and positive (r=0.836, p=0.000). In addition, the ICIQ-FLUTS showed moderate and negative correlation with the total score of UQOL (r=-0.691, p=0.017). Conclusion: The Portuguese version of the ICIQ-FLUTS questionnaire showed strong correlation to ICIQ-SF questionnaire and satisfactory values to test-retest and internal consistency.

Translation, cultural adaptation and validation of "Pregnancy Experience Scale" for Brazilian pregnant / Tradução, adaptação cultural e validação da "Pregnancy Experience Scale" para gestantes brasileiras / Traducción, adaptación y validación de la "Pregnancy Experience Scale" para brasileñas embarazadas

Abstract Introduction: The analysis of maternal psychosocial stress during pregnancy can be an important intervention tool for maternal and infant health. Objective: To translate, culturally adapt and validate the Pregnancy Experience Scale - Brief Version - into Brazilian Portuguese for Brazilian pregnant women. Method: The scale was carried out according to the guidelines recommended by Beaton and his collaborators. Data were collected between January and September of 2016, in hospitals, basic health units, and community. In total, 206 pregnant women with an average age of 25.01 ± 6.44 years and gestational age of 25.5 ± 8.72 pregnancy weeks answered the scale for the process of psychometric analysis and validation. Results: The results indicated a two-dimensional model of the scale with two factors: Positive Experiences and Negative Experiences. The reliability was established through Cronbach's Alpha Test (α > 0.70). The value found for the positive experiences factor was appropriate, α = 0.77. The same happened to the Negative Experiences factor, α = 0.80. These values provide evidence of the scale reliability. The convergent and concurrent validity of the instrument was established. Conclusion: The result of the psychometric study of the scale pointed out that the Pregnancy Experience Scale is an important intervention tool for the health care of mother and newborn, besides being a useful instrument to assess the experience of the women with the pregnancy, especially, the level of psychosocial stress, contributing to broaden the research in this area and subsidize support strategies for this population and women's health policies.

Pelvic floor and abdominal muscle cocontraction in women with and without pelvic floor dysfunction: a systematic review and meta-analysis.

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.

Prenatal exposure to gestational diabetes mellitus increases developmental defects in the enamel of offspring.

BACKGROUND AND OBJECTIVE: Gestational diabetes mellitus (GDM) is associated with short- and long-term maternal and perinatal repercussions. Our objective was to evaluate the long-term consequences of intrauterine exposure to hyperglycemia on Developmental Defects of Enamel (DDE) in offspring. RESULTS: Overall, 50 children of women with GDM and 250 children of normoglycemic women participated, the latter serving as controls. Children were examined at the age between 3 and 12 years. In addition to physical examination, two independent observers examined and rated photographs to identify specific types of DDE in a blinded fashion. Among offspring of mothers with GDM, rates of DDE (all types combined) and hypoplasia (specific type) were significantly higher (p<0.001, p = 0.04), in comparison to offspring of normoglycemic mothers. Considering only the affected teeth (1060 in GDM category; 5499 in controls), rates of DDE (all types combined) were significantly higher for total teeth (p <0.001) and deciduous teeth (p<0.001), but not permanent teeth. In specific types of DDE involving deciduous teeth, rates of demarcate opacity were significantly higher (p<0.001; canine and 2nd mandibular molars) and hypoplasia (p <0.001; 2nd maxillary molars and 2nd mandibular molars). In permanent teeth, the rate of diffuse opacity in association with GDM was significantly higher (p<0.001; maxillary central incisors and 1st maxillary molars). CONCLUSION: GDM was associated with the adverse effects of DDE on offspring. This study lays the foundation for future studies to determine the impact of GDM on long-term risk of DDE.

The influence of hyperglycemia on the remodeling of urethral connective tissue in pregnant rats.

OBJECTIVE: To analyze the distribution and quantification of the key structural extracellular matrix components of the urethral tissue in a rat model of hyperglycemia and pregnancy. STUDY DESIGN: A total of 120 female Wistar rats were distributed into the following four experimental groups: virgin, pregnant, hyperglycemic and hyperglycemic + pregnant groups. The urethra was harvested for histochemical, morphometric, immunohistochemical, Western blot and glycosaminoglycan analyses. All protocols were approved by the Institutional Animal Care and Use Committee of Botucatu Medical School (process number 828-2010). RESULTS: The hyperglycemic + pregnant group showed significantly increased stiffness in urethral tissue. The total striated muscle was decreased, with increased deposition of collagen fibers around the muscle fibers and a change in the organization of the collagen fibrils. An increase in the relative collagen type I/III ratio and a decrease in total glycosaminoglycans were also observed. CONCLUSIONS: This study provides the first line of experimental evidence supporting a metabolic relationship between hyperglycemia and urethral remodeling of connective tissue in pregnant rats. The different organization of the collagen fibrils and the profile of glycosaminoglycans found in urethral samples suggest that the pathology of the urethral fibromuscular system could be related to hyperglycemia-induced pelvic floor dysfunction in women, which has direct clinical implications with the possibility to develop new multidisciplinary treatments for improving the health care of these women.

Effects of short-term severe and long-term mild STZ-induced diabetes in urethral tissue of female rats.

AIMS: To estimate and compare the alterations in the urethral tissues of female rats with two diabetes models: short-term severe and long-term mild diabetes. METHODS: To induce mild diabetes (blood glucose levels between 120 and 300 mg/dl), female newborns received streptozotocin (100 mg/kg body weight, sc route), and to induce short-term severe diabetes (blood glucose levels > 300 mg/d), adult animals received streptozotocin (40 mg/kg, iv route). The rats were killed on day 133 of the experimental via an i.p. Thiopentax® injection of 80 mg/kg, and the urethrovaginal tissues were harvested. Morphometric, pathological, immunohistochemical, and ultrastructural analyses were conducted. RESULTS: In the long-term mild diabetes group, collagen deposition, severe fibrosis, lipid droplets and numerous subsarcolemmal, and intermyofibrillar mitochondria were observed. In the short-term severe diabetes group, centrally located myonuclei and a significantly reduced striated muscle area were noted. Both diabetic models exhibited similar immunohistochemistry patterns, with changes from fast to slow fibers and a decrease in the numbers of fast fibers. CONCLUSIONS: Either long-term mild hyperglycemia or short-term severe hyperglycemia have detrimental impacts on muscle health. They are both involved in the failure to maintain healthy skeletal muscle that may contribute to the development of pelvic floor dysfunctions via different pathways. These results have important implications for monitoring and prevention strategies for improving the quality of life of women with diabetes mellitus and pelvic floor muscle dysfunction. Neurourol.

Prevalence and knowledge of urinary incontinence and possibilities of treatment among low-income working women / Prevalência e conhecimento sobre incontinência urinaria e possibilidades de tratamentos entre mulheres trabalhadoras de baixa renda

Abstract Introduction: Urinary incontinence (UI) can affect women's lives in all areas, including in the occupational context, due to an uncomfortable workplace, incorrect positions for long periods of time and the handling of heavy items. Another worrying aspect is that the knowledge about urinary incontinence, in the health area, and its forms of treatment is still small among the low-income population. Objective: To verify the prevalence and knowledge about urinary incontinence and treatment possibilities among low-income working women. Methods: A cross-sectional study carried out on working women of a poultry processing plant. Results: The study included 136 women with an average age of 33.7 ± 9.7 years; body mass index of 26.6 ± 5.6 kg/m2; parity of 2.1 ± 1.1 children; monthly income of 2.3 ± 1 minimum wages. Of those interviewed, 63.9% were white; 44.8% had incomplete primary education; 52.9% were single; 53.6% underwent cesarean section delivery; and of those who underwent normal labor delivery, 86.6% underwent episiotomy. The prevalence of urinary incontinence was found to be 2.9%, and among the women affected, two reported that UI led to sexual, social, water and occupational restriction, and one of them believes that UI interferes with her concentration and productivity in the workplace. Regarding health knowledge, 46.3% had never heard of urinary incontinence before, and more than half (66.1%) did not know about the existence of medical treatment. All women interviewed (100%) were unaware of the existence of physiotherapeutic treatment. Conclusion: The prevalence of urinary incontinence was among those interviewed was small, however, the knowledge about the symptoms and possibilities of medical, and mainly physiotherapeutic treatment. is scarce among these women. This study allows to alert and to guide the health professionals and the society about the importance of actions that promote health education in the low income population, besides allowing these women to prevent or seek the appropriate treatment in order to guarantee a better quality of life.

Resumo Introdução: A incontinência urinária pode afetar a vida da mulher em todos os âmbitos, inclusive no contexto ocupacional, devido a ambientes desfavoráveis, posições incorretas por longos períodos e carregamento de pesos. Outro aspecto preocupante é que o conhecimento em saúde sobre a perda urinária e suas formas de tratamento ainda é pequeno entre a população de baixa renda. Objetivo: Verificar a prevalência e o conhecimento sobre incontinência urinária e possibilidades de tratamentos entre mulheres trabalhadoras de baixa renda. Métodos: Trata-se de estudo transversal, realizado em mulheres trabalhadoras em uma empresa frigorífica de aves. Resultados: Participaram do estudo 136 mulheres com média de idade de 33,7 ± 9,7 anos; índice de massa corporal de 26,6± 5,6 Kg/m2; paridade de 2,1 ± 1,1 filhos; renda mensal de 2,3 ± 1 salários mínimos. Das entrevistadas, 63,9% eram brancas; 44,8% com ensino fundamental incompleto; 52,9% eram solteiras; 53,6% realizaram parto cesárea; e das mulheres que fizeram parto vaginal, 86,6% realizaram episiotomia. A prevalência de perda urinária encontrada foi de 2,9%, e entre as mulheres afetadas, duas relataram que a IU levou a restrição sexual, social, hídrica e ocupacional, sendo que uma delas, acredita que a perda de urina interfere na concentração e na sua produtividade no trabalho. Sobre o conhecimento em saúde, 46,3% nunca ouviram falar sobre o assunto da incontinência, sendo que mais da metade (66,1%) não sabiam da existência de tratamento médico e todas as entrevistadas (100%) não conheciam a existência de tratamento fisioterapêutico. Conclusão: A prevalência de IU em mulheres trabalhadoras de baixa renda no setor frigorífico foi pequena, entretanto, o conhecimento sobre a incontinência urinária e as possibilidades de tratamento é escasso entre estas mulheres. Este estudo permite alertar e orientar os profissionais da saúde e a sociedade sobre a importância de ações que promovam educação em saúde na população de baixa renda, além de permitir que estas mulheres se previnam ou procurem o tratamento adequado e garantam melhor qualidade de vida.

Mesenchymal stem cell therapy in a rat model of birth-trauma injury: functional improvements and biodistribution.

INTRODUCTION AND HYPOTHESIS: We evaluated the potential role of human mesenchymal stem cells (hMSCs) in improvement of urinary continence following birth-trauma injury. METHODS: Human MSCs were injected periurethrally or systemically into rats immediately after vaginal distention (VD) (n = 90). Control groups were non-VD (uninjured/untreated, n = 15), local or systemic saline (injection/control, n = 90), and dermofibroblast (cell therapy/control, n = 90). Leak-point pressure (LPP) was measured 4, 10, and 14 days later. Urethras were morphometrically evaluated. In another sets of VD and non-VD rats, the fate of periurethrally injected hMSC, biodistribution, and in vivo viability was studied using human Alu genomic repeat staining, PKH26 labeling, and luciferase-expression labeling, respectively. RESULTS: Saline- and dermofibroblast-treated control rats demonstrated lower LPP than non-VD controls at days 4 and 14 (P < 0.01). LPP after systemic hMSC and periurethral hMSC treatment were comparable with non-VD controls at 4, 10, and 14 days (P > 0.05). Local saline controls demonstrated extensive urethral tissue bleeding. The connective tissue area/urethral section area proportion and vascular density were higher in the local hMSC- versus the saline-treated group at 4 and 14 days, respectively. No positive Alu-stained nuclei were observed in urethras at 4, 10, and 14 days. PKH26-labelled cells were found in all urethras at 2 and 24 h. Bioluminescence study showed increased luciferase expression from day 0 to 1 following hMSC injection. CONCLUSIONS: Human MSCs restored the continence mechanism with an immediate and sustained effect in the VD model, while saline and dermofibroblast therapy did not. Human MSCs remained at the site of periurethral injection for <7 days. We hypothesize that periurethral hMSC treatment improves vascular, connective tissue, and hemorrhage status of urethral tissues after acute VD injury.

[Changes in the extracellular matrix due to diabetes and their impact on urinary continence]. / Alterações da matriz extracelular causadas pelo diabetes: o impacto sobre a continência urinária.

The prevalence of urinary incontinence in diabetic pregnant women is significantly high two years after cesarean section. Incontinence can be the most common consequence of hyperglycemia compared to other complications. Thus, identifying the risk factors for the development of urinary incontinence in diabetes is the major aim in the prevention of this very common condition. Recent surveys have shown that not only muscle but also the urethral extracellular matrix play an important role in the mechanism of urinary continence. Translational work on rats by our research group showed that diabetes during pregnancy damages the extracellular matrix and urethral striated muscle, a fact that may explain the high prevalence of urinary incontinence and pelvic floor dysfunction in women with gestational diabetes mellitus. Diabetes affects the expression, organization and change in extracellular matrix components in different organs, and tissue remodeling and fibrosis appear to be a direct consequence of it. Therefore, understanding the impact of modifiable risk factors, such as diabetes, which involves using preventive strategies, can reduce the rates of urinary incontinence and the health care costs, and improve the quality of life of women, especially during pregnancy and postpartum.

Alterações da matriz extracelular causadas pelo diabetes: o impacto sobre a continência urinária / Changes in the extracellular matrix due to diabetes and their impact on urinary continence

A prevalência de incontinência urinária em gestantes diabéticas é significantemente elevada e persiste por até dois anos após o parto cesárea, podendo ser a sequela mais frequente da hiperglicemia gestacional comparada a outras complicações. Dessa forma, identificar os fatores de risco para o desenvolvimento da incontinência urinária em diabéticas é o principal objetivo na prevenção dessa condição tão comum. Pesquisas recentes apontam que não apenas o músculo uretral mas também a matriz extracelular uretral desempenham papel importante no mecanismo da continência urinária. Os trabalhos do nosso grupo de pesquisa evidenciaram que, em ratas, o diabetes durante a prenhez lesa a matriz extracelular e o músculo estriado uretral, o que pode explicar a alta prevalência de incontinência e disfunção do assoalho pélvico em mulheres com diabetes mellitus gestacional. O diabetes exerce efeito sobre a expressão, organização e alteração dos componentes da matriz extracelular em diversos órgãos, e a remodelação do tecido e a fibrose parecem ser uma consequência direta dele. Assim, a compreensão do impacto de fatores de risco modificáveis, como o diabetes, permitirá que, utilizando estratégias preventivas, reduzamos as taxas de incontinência urinária, bem como os custos de assistência à saúde, e melhoremos a qualidade de vida das mulheres, especialmente na gestação e no pós-parto.
