Objectives To systematically review studies evaluating one or more components of physical fitness (PF) in pregnant women, to answer two research questions: (1) What tests have been employed to assess PF in pregnant women? and (2) What is the validity and reliability of these tests and their relationship with maternal and neonatal health? Design A systematic review. Data sources PubMed and Web of Science. Eligibility criteria Original English or Spanish full-text articles in a group of healthy pregnant women which at least one component of PF was assessed (field based or laboratory tests). Results A total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (ie, 52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6) or the relationship of PF with maternal and neonatal health (n=16). Conclusion Physical fitness has been assessed through a wide variety of protocols, mostly lacking validity and reliability data, and no consensus exists on the most suitable fitness tests to be performed during pregnancy., University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence: Unit of Excellence on Exercise and Health (UCEES), Junta de Andalucia, Consejeria de Conocimiento, Investigacion y Universidades and European Regional Development Fund (ERDF) SOMM17/6107/UGR

Objectives: The aim of this study was to explore the associations of abdominal muscles thickness and inter-recti distance (IRD) at late pregnancy with birth-related outcomes and umbilical cord blood (CB) gas values. Design: cross-sectional study. Setting: Sport and Health University Research Institute Sample: One hundred and fifty-two pregnant women. Main outcome measures: The thickness of the abdominal muscles (transverse abdominis [TrA], internal [IO] and external obliques [EO]) and the IRD were measured by ultrasound at the 34th gestational week. Birth outcomes were collected from obstetric medical records. Umbilical CB gas concentrations were assessed after birth using a blood analyzer. Results: Greater TrA and IO thickness were associated with a higher venous CB PO2 value, both at muscular rest (respectively, p

The aims of this cross-sectional study were to describe objectively measured sedentary time (ST) and physical activity (PA) levels in Spanish pregnant women, to analyze the degree of compliance with PA guidelines during the early second trimester of pregnancy and to explore sociodemographic and clinical factors associated with meeting these PA guidelines. One hundred and thirty-four Caucasian pregnant women were recruited between October 2015 and October 2017 to participate in this study. Triaxial accelerometers were used to analyze ST andPA levels for seven consecutive valid days. Womenspent512 ± 92.1 minutes daily in sedentary behaviors, and 85 ± 108.2 minutes in moderate-to-vigorous physical activity (MVPA) in bouts of at least 10 minutes. They walked on average 7436 ± 2410steps per day. Only 22% of the study sample complied with the PA guidelines. Having an University degree was related with threefold higher odds of compliance with the PA guidelines (95% confidence interval: 0.096-0.913

Objective: To determine the presence of anti-SARS-CoV-2 antibodies in colostrum and mature milk in women who had SARS-CoV-2 infection during pregnancy or at delivery; to investigate the correlation between anti-SARS-CoV-2 antibodies in milk with antibody in maternal blood, severity of infection and time-interval from active illness; and to evaluate immunoglobulin evolution from colostrum to mature milk. Design: prospective cohort-study Setting: six hospitals in Spain and Hong-Kong. Sample: pregnant women with confirmed SARS-CoV-2 infection during pregnancy or at delivery. Methods: Colostrum and mature milk were collected by manual expression with strict contact precautions. Colostrum samples were tested with rRT-PCR-SARS-CoV-2 and both, maternal milk and serum were tested against SARS-CoV-2 specific immunoglobulin M, A and G reactive to receptor binding domain of SARS-CoV-2 spike protein-1. Results: All rRT-PCR-SARS-CoV-2 tested negative. IgA and IgG were present in 111/135 (82.2%) and 2/135 (1.5%) colostrum samples and 27/81 (33.3%) and 0/81 mature milk samples, respectively. Concentrations of immunoglobulins were not associated with the timing of infection but women with SARS-CoV-2 pneumonia had higher levels of IgA and IgG in colostrum than those who were asymptomatic or had mild symptoms. Conclusion: No SARS-CoV-2 virus was found in human milk, however, high levels of antibodies were found in colostrum, specially IgA, irrespective of the time of infection. All women should be encouraged to breastfeed, undertaking strict contact precautions when there is active disease. Funding: Spanish Government grant (Instituto de Salud Carlos III: COV20/00188).

This research was funded by the Health Institute Carlos III (FEDER funds), grant number PI17/01743, and donations from particular endometriosis women that believed in this project from the beginning. It was also partly supported by funds from the PAIDI group CTS-206 (Oncologia Basica y Clinica). This study takes place thanks to the additional funding from the University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES)., Aim: The ‘Physio-EndEA’ study aims to explore the potential benefits of a therapeutic exercise program (focused on lumbopelvic stabilization and tolerance to exertion) on the health-related quality of life (HRQoL) of symptomatic endometriosis women. Design: The present study will use a parallel-group randomized controlled trial design. Methods: A total of 22 symptomatic endometriosis women will be randomized 1:1 to the Physio-EndEA or usual care groups. The ‘Physio-EndEA’ program will consist of a one-week lumbopelvic stabilization learning phase followed by an eight-week phase of stretching, aerobic and resistance exercises focused on the lumbopelvic area that will be sequentially instructed and supervised by a trained physiotherapist (with volume and intensity progression) and adapted daily to the potential of each participant. The primary outcome measure is HRQoL. The secondary outcome measures included clinician-reported outcomes (pressure pain thresholds, muscle thickness and strength, flexibility, body balance and cardiorespiratory fitness) and patient-reported outcomes (pain intensity, physical fitness, chronic fatigue, sexual function, gastrointestinal function and sleep quality). Discussion: Findings of this study will help to identify cost-effective non-pharmacological options (such as this exercise-based intervention) that may contribute to the improvement of HRQoL in symptomatic endometriosis women., Health Institute Carlos III (FEDER funds) PI17/01743, PAIDI group, University of Granada

Importance: Understanding the impact of endometriosis symptoms on patients’ activities of daily living (ADLs) is a priority to establish effective and personalized intervention programs. Objective: To explore limitations in ADLs and instrumental ADLs (IADLs) and their association with pelvic pain (PP), chronic fatigue, and pain-catastrophizing thoughts among women with endometriosis. Design: Cross-sectional study. Setting: Spain. Participants: Two hundred thirty women with endometriosis. Outcomes and Measures: Information regarding performance of ADLs (Barthel Index) and IADLs (Lawton–Brody questionnaire), PP intensity (Numeric Rating Scale), chronic fatigue (Piper Fatigue Scale), and pain-catastrophizing thoughts (Pain Catastrophizing Scale) was gathered. Multivariate regression analyses were created, and mediating effects of fatigue and pain-catastrophizing thoughts on the association between PP and ADL and IADL limitations were assessed. Results: The prevalence of limitations in at least one ADL and one IADL was 22.6% (95% confidence interval [CI] [17.2, 28.1]) and 39.1% (95% CI [32.8, 45.5]), respectively. Limitations in bowel continence, housework, shopping, and meal preparation were reported most frequently. Women reporting severe PP showed higher risk for ADL (odds ratio [OR] = 3.33, 95% CI [1.10, 10.10]) and IADL (OR = 7.99, 95% CI [2.86, 22.34]) limitations. Chronic fatigue and pain-catastrophizing thoughts were also positively related to ADL–IADL limitations, showing a mediating effect on the association between PP and ADL–IADL limitations. Conclusions and Relevance: This study reveals the widespread presence of difficulties in ADL–IADL performance among women with endometriosis, with some symptoms underlying these difficulties in occupational performance. This study points to the need for cost-effective occupational therapy interventions for affected women. What This Article Adds: This research shows that the occupational performance of women with endometriosis is frequently impaired; therefore, the effectiveness of occupational therapy interventions should be addressed in the near future.

Background Physical fitness (PF) is a powerful marker of health throughout the lifespan. In pregnant women, higher PF is associated with better maternal and fetal health, better delivery outcomes and earlier postpartum recovery. The assessment of PF during pregnancy requires special considerations to preserve fetal and maternal health; thus, providing a compilation of the most frequently used fitness tests, and assessing their validity, reliability, and association with maternal and neonatal health-related outcomes is of scientific and clinical interest. Objectives To systematically review studies evaluating one or more components of PF in pregnant women, to answer two research questions: 1) What fitness tests have been previously employed in pregnant women? and 2) What is the validity and reliability of these tests and their relationship with health-related outcomes? Data Sources PubMed and Web of Science. Methods Two independent reviewers systematically examined the articles in each database. The information from the included articles was summarized by a single researcher. Results A total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (i.e.,52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6), or the relationship of PF with maternal and neonatal health-related outcomes (n=16). Conclusion PF during pregnancy has been assessed through a wide variety of protocols, mostly lacking validity and reliability data. PROSPERO Registration Number: CRD42018117554 Key points Physical Fitness during pregnancy has been assessed through a wide variety of tests (n=191) and different protocols (n=149). We found that cardiorespiratory fitness has been assessed with 75 different protocols (many of them made ad hoc), muscular fitness with 16 different protocols, flexibility with 13 different protocols, and balance with 40 different protocols. Most of the protocols lacked validity and reliability data, which limits the confidence on the association of fitness with maternal and neonatal health-related outcomes, which is still scarce. We advocate for an expert consensus to be developed in the following years to achieve the goal of appropriate and effective PF assessment during pregnancy. Running Heading Assessing physical fitness during pregnancy: validity, reliability and relationship with maternal and neonatal health-related outcomes.

Objective To explore hypersensitivity to pain and musculoskeletal impairments in the lumbopelvic area in women with and without endometriosis. Methods This cross-sectional study included 66 women (41 women with endometriosis and 25 healthy women). Pain and related catastrophizing thoughts were assessed through a numeric rating scale, pressure pain thresholds (PPTs), the slump test, and the Pain Catastrophizing Scale. Lumbopelvic muscles were evaluated through ultrasound imaging, flexor/extensor resistance tests, and the lumbopelvic stability test. Results Women with endometriosis showed increased self-reported intensity of current pelvic pain (CuPP), reduced local PPTs (42.8–64.7% in the affected area, P-value Conclusions The presence of pain sensitization signs and lumbopelvic impairments, more pronounced in patients with stage IV endometriosis and moderate/severe CuPP, warrants the development of rehabilitation interventions targeting pain and lumbopelvic impairments in women with endometriosis.

To explore work performance status in Spanish women with endometriosis and to identify those endometriosis-related symptoms that potentially contribute to the reduced work performance.Cross-sectional study.Spain.Women with endometriosis working at enrolment (n = 148).Work performance status was assessed through the Work Role Functioning Questionnaire (WRFQ). Endometriosis-related symptoms (pelvic pain, catastrophizing thoughts related to pain, chronic fatigue, sleep quality, mood status, gastrointestinal discomfort and social support) were also evaluated through validated scales. Statistical analyses were performed through multivariate linear regression analyses.Work performance status.Median WRFQ score was 72.0, with the lowest scores found in demands related to worker's needs to manage the workday from beginning to end and those dynamic and static physical loads required in the conduct of work duties. Severe pelvic pain, depressive mood and poorer sleep quality was inversely related to work performance status (p-values0.020). Finally, self-perceived social support was borderline associated with better work performance (p = 0.057). Considered together, these four psychosocial factors were responsible to explain the 37.9 % of the limitations on work performance observed in our study sample.Spanish women with endometriosis reported lower WRQF scores (predominantly in work scheduling and physical demands) in comparison with previous studies on Spanish healthy adults. Psychosocial factors, including pelvic pain, sleep quality and depressive mood are related with work performance status. Thus, the effectiveness of physical and psychological rehabilitation programs in work productivity in women with endometriosis should be evaluated in the close future.

We explored (a) the associations between self-reported maternal physical fitness and birth outcomes; (b) whether self-reported maternal physical fitness (PF) is related to the administration of oxytocin to induce or stimulate labour. Pregnant women from the GESTAFIT project randomized controlled trial (n = 117) participated in this prospective longitudinal study. Maternal physical fitness was assessed through the International Fitness Scale at the 34th gestational week. Maternal and neonatal birth outcomes and oxytocin administration were collected from the obstetric medical records. Umbilical arterial and venous cord blood gas were analysed immediately after birth. Selfreported overall fitness, cardiorespiratory fitness, muscular strength and flexibility were not related to any maternal and neonatal birth outcomes (all p > 0.05). Greater speed-agility was associated with a more alkaline arterial (p = 0.04) and venous (p = 0.02) pH in the umbilical cord blood. Women who were administered oxytocin to induce or stimulate labour reported lower cardiorespiratory fitness (p = 0.013, Cohen’s d = 0.55; 95% confidence interval (CI): 0.14, 0.93) and flexibility (p = 0.040, Cohen´s d = 0.51; 95% CI: 0.09, 0.89) compared to women who were not administered oxytocin. Greater maternal physical fitness during pregnancy could be associated with better neonatal birth outcomes and lower risk of needing oxytocin administration., Regional Ministry of Health of the Junta de Andalucía (PI-0395-2016), Research and Knowledge Transfer Fund (PPIT) 2016, Excellence Actions Programme: Scientific Units of Excellence (UCEES), Regional Ministry of Economy, Knowledge, Enterprises, University, European Regional Development Funds (ref.

In the last years, the variety and consumption of cosmetics and personal care products (PCPs) have greatly increased, although the long-term adverse effects to low doses of chemicals used in their production and with proven hormone-mimicking properties have been still poorly addressed. Among these endocrine disrupting chemicals (EDCs), parabens, benzophenones, bisphenols, and phthalates are the most widely found in these products. Given the estrogenic-dependent nature of the endometrium, it has been hypothesized the potential contribution of these EDCs contained in cosmetics and PCPs in the risk of endometriosis. In this book chapter, we have summarized the current evidence supporting this hypothesis, highlighting epidemiological, in vivo, and in vitro studies that have addressed the potential influence of parabens, benzophenones, bisphenols, and phthalates in the origin and progression of this chronic feminine disease.

This paper is part of the thesis developed by A. Mundo-López in the Official Doctoral Program in Clinical Medicine and Public Health of the University of Granada., Aim: To analyze the levels of chronic fatigue in Spanish women with endometriosis and its relationship with their psychosocial status and quality of life (QoL). Methods: A total of 230 Spanish women with a clinical diagnosis of endometriosis were recruited. Chronic fatigue (Piper Fatigue Scale) and pelvic pain (Numeric Rating Scale) were evaluated. An on-line battery of validated scales was used to assess psychosocial status [Hospital Anxiety and Depression Scale, Scale for Mood Assessment, Pain Catastrophizing Scale, Pittsburgh Sleep Quality Index, Gastrointestinal Quality of Life Index, Female Sexual Function Index and Medical Outcomes Study-Social Support Survey] and QoL [Endometriosis-Health Profile questionnaire-30]. Associations between fatigue and both psychosocial and QoL outcomes were explored through multivariate regression models. Results: One-third and one-half of women showed moderate and severe fatigue, respectively. Fatigue was associated with higher anxiety and depression, poorer sleep quality, poorer sexual functioning, worse gastrointestinal health, higher catastrophizing thoughts, higher anger/hostility scores and lower QoL (p-values < 0.050). Moreover, fatigue and catastrophizing thoughts showed a mediating effect on the association between pelvic pain and QoL. Conclusion: This work reveals the important role of fatigue in the association between pain, psychosocial status, and QoL of Spanish women with endometriosis., Health Institute Carlos III (ISCIII)-FEDER PI17/01743, PAIDI group (Oncologia Basica y Clinica) funds CTS-206, University of Granada, Plan Propio de Investigacion 2016, Excellence action: Units of Excellence, University of Granada, Plan Propio de Investigacion 2016, Excellence action: Unit of Excellence on Exercise and Health (UCEES), Junta de Andalucia SOMM17/6107/UGR, European Union (EU) SOMM17/6107/UGR

The authors are indebted with all participants, without whom this work would not have been possible. We are grateful to Ana Yara Postigo-Fuentes for her assistance with the English language. This paper is part of the PhD thesis developed by A. Lara-Ramos in the Official Doctoral Programme in Clinical Medicine and Public Health of the University of Granada., Aim: To explore endometriosis-related fatigue (ERF), health-related fitness, sleep quality, and health-related quality of life (HRQoL) in women with endometriosis in comparison with matched controls. Methods: Twenty-five affected women and twenty-five age and height-matched women without endometriosis were included. ERF was assessed through the Piper Fatigue Scale; health-related fitness was assessed through the Schöber, flamingo, and 6-min walking tests and dynamometry; and body composition was assessed through impedanciometry. Self-perceived physical fitness, sleep quality, and HRQoL were assessed through the International Fitness Scale, the Pittsburgh Sleep Quality Index, and the 12-item Short Form Health Survey, respectively. Results: Affected women exhibited higher levels of ERF than controls, increased fat mass, and physical deconditioning (reduced back strength, lumbar flexibility, body balance, and functional capacity, p-values < 0.050). Moreover, cases also had poorer perceived physical fitness, sleep quality, and HRQoL (p-value < 0.050). Finally, we observed deteriorated health-related fitness, sleep quality, and HRQoL in those women with endometriosis with higher levels of ERF. Conclusions: This study constitutes the first evidence that women with endometriosis describe a generalized physical deconditioning, even more pronounced in affected women with higher levels of ERF. Further studies assessing the efficacy of rehabilitation interventions to face these physical impairments in women with endometriosis are warranted., Health Institute Carlos III (ISCIII)-FEDER PI17/01743, PAIDI group CTS-206, University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES), Junta de Andalucia, Consejeria de Conocimiento, Investigacion y Universidades, European Union (EU) SOMM17/6107/UGR

Aim: The aim of this study was to explore associations of urinary concentrations of bisphenols A (BPA), S (BPS), and F (BPF) and of thiobarbituric acid reactive substances (TBARS) with the risk of endometriosis in women of childbearing age. Methods: This case&ndash, control study enrolled 124 women between January 2018 and July 2019: 35 women with endometriosis (cases) and 89 women without endometriosis undergoing abdominal surgery for other reasons (controls). Endometriosis was diagnosed (cases) or ruled out (controls) by laparoscopic inspection of the pelvis and the biopsy of suspected lesions (histological diagnosis). Fasting urine samples were collected before surgery to determine concentrations of BPA, BPS, BPF, and TBARS. Associations of bisphenol and TBARS concentrations with endometriosis risk were explored with multivariate logistic and linear regression analyses. Results: After adjustment for urinary creatinine, age, BMI, parity, and residence, endometriosis risk was increased with each 1 log unit of BPA [OR 1.5, 95%CI 1.0&ndash, 2.3] and &Sigma, bisphenols [OR 1.5, 95%CI 0.9&ndash, 2.3] but was not associated with the presence of BPS and BPF. Classification of the women by tertiles of exposure revealed statistically significant associations between endometriosis risk and the second tertile of exposure to BPA [OR 3.7, 95%CI 1.3&ndash, 10.3] and &Sigma, bisphenols [OR 5.4, 95%CI 1.9&ndash, 15.6]. In addition, TBARS concentrations showed a close-to-significant relationship with increased endometriosis risk [OR 1.6, 2.8], and classification by TBARS concentration tertile revealed that the association between endometriosis risk and concentrations of BPA [OR 2.0, 4.1] and &Sigma, bisphenols [OR 2.2, 4.6] was only statistically significant for women in the highest TBARS tertile (&gt, 4.23 &mu, M). Conclusion: Exposure to bisphenols may increase the risk of endometriosis, and oxidative stress may play a crucial role in this association. Further studies are warranted to verify these findings.

(a) To analyse the association of objectively measured sedentary time (ST) and physical activity (PA) during early second trimester of pregnancy with maternal and neonatal birth outcomes; (b) to explore if ST and PA differ between women with vaginal or caesarean section deliveries.Ninety-four Caucasian pregnant women (32.9 ± 4.6 years old) participated in this prospective longitudinal study. Triaxial accelerometers were used to assess ST and PA intensity levels for seven consecutive days during second trimester of pregnancy. Birth data were collected from the obstetric medical records. Umbilical cord arterial and venous blood gas (pH, partial pressure of carbon dioxide and oxygen, and oxygen saturation) were analysed after birth.After adjusting for potential confounders, greater ST was associated with higher arterial and venous cord blood partial pressure of carbon dioxide and more acidic arterial and venous pH (all, P 0.01). Moderate PA, moderate-to-vigorous PA (MVPA), total PA and steps per day were positively associated with arterial cord blood oxygen saturation (all P 0.05). Steps per day were inversely associated with gestational age at birth (P 0.01), and duration of first stage of labor (P 0.05). Total and light PA were associated with a more alkaline pH in umbilical vein (all, P 0.01). Vigorous PA was inversely associated with the Apgar score (P 0.01). No significant differences were observed in ST and PA levels between women with vaginal and women with caesarean section deliveries (all, P 0.10).Increasing PA and decreasing ST during pregnancy might promote better maternal and neonatal birth markers.

Introduction Bisphenol A (BPA) is a well-known endocrine disrupting compound. Although several studies have investigated the effect of BPA exposure and reproductive hormones in humans, results have been inconsistent. Objective To explore the cross-sectional relationship between bisphenol A (BPA) exposure and reproductive hormones/cortisol among peripubertal boys. Material and methods Urinary BPA and serum hormones were assessed in 172 boys belonging to the INMA “Environment and Childhood” Granada birth cohort in their follow-up at 9–11 years of age. BPA concentrations were quantified by liquid chromatography-mass spectrometry, and levels of serum total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and cortisol were measured by electrochemiluminescence immunoassay. Result(s) After adjustment for confounders, linear regression models showed that each natural-log unit increase in urinary BPA concentrations was associated with a 19% increase in geometric mean (GM) serum TT levels, and a 16% decrease in GM serum cortisol levels. When urinary BPA concentrations were categorized in tertiles, boys in the 3rd tertile showed 49% higher TT levels and 23% lower cortisol concentrations compared to boys in the 1st tertile. Additionally, urinary BPA concentrations were also significantly associated with higher TT:LH and TT:cortisol ratios, but not with serum LH or FSH levels. Conclusion(s) Our results suggest the possible endocrine disrupting potential of BPA during this important period of development. Although action at the testis or pituitary cannot be ruled out, our findings are compatible with a possible involvement of BPA at the adrenal gland, resulting in a differential production of androgens/cortisol. However, given the cross-sectional design of our study, the heterogeneous results reported in the literature, and the scant experimental research on BPA effects at the adrenal gland, the present findings should be interpreted with caution.

Aim To evaluate concentrations of parabens (PBs) and benzophenones (BzPs) in menstrual blood and explore related sociodemographic/lifestyle factors, and to compare between menstrual and peripheral blood concentrations in a subset of samples. Material and methods Concentrations of 4 PBs [methyl- (MeP), ethyl- (EtP), propyl- (PrP) and butyl-paraben (BuP)] and 6 BzPs [BzP-1, BzP-2, BzP-3, BzP-6, BzP-8 and 4-OH-BzP] were determined in menstrual blood from 57 women and in both menstrual and peripheral blood samples from 12 women, all healthy Spanish women of reproductive age. Socio-demographic characteristics and lifestyle habits [diet and use of cosmetics and personal care products (PCPs)] were gathered using an online questionnaire. Spearman correlation analysis was performed to examine the relationship between menstrual and peripheral blood concentrations, while multivariable linear regression was used to identify potential explanatory variables for menstrual PB and BzP concentrations. Results Globally, all menstrual blood samples had detectable levels of ≥3 compounds, and 52.6% of the samples contained ≥6 compounds. MeP, PrP, and BzP-3 were the most frequently detected compounds (detection frequencies >90.0%), with median concentrations of 1.41, 0.63, and 1.70 ng/mL of menstrual blood, respectively. Age, the use of PCPs, and consumption of some food items (meat, pasta, cheese, or dairy products) were related to the menstrual blood concentrations of some PBs/BzPs. Serum:menstrual blood ratios of PBs/BzPs ranged from 1.7 to 3.6, with no inter-matrix correlations. Conclusions This study reveals, to our knowledge for the first time, the widespread presence of several PBs and BzPs in intimate contact with gynecological tissues, although their concentrations in menstrual blood were not correlated with those in peripheral blood from the same women. These results shed light on the information provided by the menstrual blood as a potential matrix for characterizing exposure to PBs and BzPs, whose consequences for women's reproductive health need to be addressed.

This study aimed (a) to examine the construct validity of the International Fitness Scale (IFIS) to discriminate between different objectively measured physical fitness levels in pregnant women and (b) to assess the extent to which IFIS is able to discriminate between pregnant women with different levels of health-related quality of life (HRQoL). A total of 159 pregnant women were involved in the GESTAtion and FITness project: 106 pregnant women (mean age 32.7, SD 4.4 years) were included. Self-reported physical fitness-that is, cardiorespiratory fitness, muscular strength, flexibility, and overall fitness-was assessed with the IFIS. Physical fitness was objectively measured using the Bruce test, the handgrip strength test and the back-scratch test. The HRQoL was assessed with the 36-item Short Form Health Survey (SF-36). Higher self-reported physical fitness measured with IFIS was associated with higher objectively measured physical fitness (P < .05). There was a linear association so that higher self-reported physical fitness (ie, IFIS; regardless of the fitness component) was related to greater General Health dimension scores (P < .05). Moreover, higher self-reported physical fitness (all components except muscular strength) was associated with better Physical Functioning, lower Bodily Pain and higher Vitality scores (ie, SF-36 components). This linear trend was not seen for objectively measured physical fitness. The results of this study suggest that IFIS might be a useful tool for identifying pregnant women with low or very low physical fitness and with low quality of life health-related. Further research should elucidate whether IFIS can identify women with pregnancy complications before it can be implemented in clinical practice.

Introduction Childhood obesity is one of the most serious public health challenges of our times. Although an important body of experimental evidence highlights the obesogenic potential of endocrine disruptors such as bisphenol A (BPA), the epidemiological evidence remains inconclusive and limited. Objective To assess associations between urinary BPA concentrations and several adiposity measures in peripubertal boys from the Environment and Childhood (INMA) cohort in Granada, Spain. Material and methods BPA concentrations were determined in spot urine samples from 298 boys aged 9–11, and their weight, height, waist circumference, and percentage body fat mass were measured. Overweight/obesity was defined as BMI z-score ≥85th percentile and abdominal obesity as waist-to-height ratio (WHtR) ≥0.5. Associations were assessed using multivariable linear and logistic regression models. Results In adjusted models, each natural log-unit increase in urinary BPA concentrations was associated with higher BMI z-score (β = 0.22; 95%CI = 0.03, 0.41) and increased odds of overweight/obesity (OR = 1.46; 95%CI = 1.05, 2.05). Children with higher BPA concentrations had higher WHtR values (β = 0.007; 95%CI = −0.001, 0.015), and BPA was associated with a greater risk of abdominal obesity (OR = 1.45; 95%CI = 1.03, 2.06). No associations were found with % body fat mass. Conclusions BPA may exert an obesogenic effect in peripubertal boys, potentially increasing the risk of overweight/obesity, especially abdominal obesity. However, these results should be interpreted with caution given the modest sample size and the possibilities of reverse causality and residual confounding by diet and lifestyle patterns.

Low back pain affects around 50% of pregnant women and presents significant morbidity and persistence for years in 20% of postpartum women who report that pain. Numerous studies have documented gait alterations during pregnancy and postpartum. Therefore, an analysis of the relationship between certain gait parameters and low back pain was attempted using low-cost validated instrumented insoles. This work presents a longitudinal cohort study carried out during routine gynecological follow-up visits in the first, second, and third trimesters of pregnancy at an Obstetrics and Gynecology Service. Sample size was 62. Plantar pressure data were collected with specially designed instrumented insoles containing four force sensors to measure peak pressure, center of pressure, and stance phase time in each foot and in each pregnancy trimester. The analysis was carried out on a two-dimensional level, simultaneously considering the data from both feet using Hotelling’s T2 test. This longitudinal study detected relationships between certain gait parameter changes and low back pain during pregnancy. It revealed a cyclic tendency of low back pain prevalence with a maximum in the second trimester and a decrease in the third trimester, which was correlated with alterations of the pregnant gait: excessive foot pronation and rearfoot pressure increase., This work was funded by the Junta de Andalucía (Spain) under Project P10-TIC5997. This project was partially supported by the European Regional Development Funds (ERDF).

To explore the relationship of urinary concentrations of different congeners of benzophenones and parabens with the utilization of cosmetics and personal care products (PCPs) and their impact on the risk of endometriosis, and to evaluate the influence of oxidative stress on associations found.This case-control study comprised a subsample of 124 women (35 cases; 89 controls). Endometriosis was confirmed (cases) or ruled out (controls) by laparoscopy, with visual inspection of the pelvis and biopsy of suspected lesions (histological diagnosis). Urinary concentrations of benzophenone-1 (BP-1), benzophenone-3 (BP-3), 4-hydroxibenzophenone (4-OH-BP), methyl- (MeP), ethyl- (EtP), propyl- (PrP), and butyl-paraben (BuP), and biomarkers of oxidative stress [lipid peroxidation (TBARS) and total antioxidant power (TAP)] were quantified. Information was gathered on the frequency of use of cosmetics and PCPs. Associations between the frequency of cosmetics/PCP use, urinary concentrations of benzophenones and parabens, oxidative stress, and endometriosis risk were explored in logistic and linear multivariable regression analyses.The frequency of utilization of certain cosmetics and PCPs was significantly associated with urinary concentrations of benzophenones and parabens. After adjustment for potential confounders, the risk of endometriosis was increased in women in the second versus first terciles of MeP (OR = 5.63; p-value0.001), BP-1 (OR = 5.12; p-value = 0.011), BP-3 (OR = 4.98; p-value = 0.008), and ƩBPs (OR = 3.34; p-value = 0.032). A close-to-significant relationship was observed between TBARS concentrations and increased endometriosis risk (OR = 1.60, p-value = 0.070) and an inverse association between TAP concentrations and this risk (OR = 0.15; p-value = 0.048). Oxidative stress results did not modify associations observed between benzophenone/paraben exposure and endometriosis risk.Our findings indicate that the frequency of cosmetics and PCP utilization is a strong predictor of exposure to certain benzophenone and paraben congeners. These compounds may increase the risk of endometriosis in an oxidative stress-independent manner. Further studies are warranted to corroborate these findings.

Purpose This study describes a new methodology—the cold pressor gel test (CPGT)—for delivering an accessible experimental pain stimulus, which is reproducible and safe for functional MRI (fMRI). Methods The cold pressor test was modified to put safety precautions into the CPGT. The material used is cool gelled water with a thickening product, which provides a stable temperature at 0.2 °C. Thirteen women with chronic pelvic pain were scanned using a 3 Tesla (T) MR scanner equipped with a 12-channel head coil. Changes in BOLD activation during cold-induced pain were estimated. Results The results have demonstrated that gel substances maintain a stable temperature during the experiment, resulting in an insignificant variation. Before the experiment, the mean temperature was 0.2 ± 0.11 °C, and at the end it was 0.7 ± 0.15 °C. The time taken by participants to reach the maximum level of pain during the CPGT was 56.92 ± 11.09 s. The pain intensity during the experiments was 6.92 ± 1.66 on the visual analog scale (VAS). The fMRI analysis showed significant BOLD activation in the main brain regions involved in chronic pain processing. Conclusion The CPGT is an experimental tool to deliver pain that is easily reproducible, particularly in brain functional imaging studies. Moreover, it is cost-effective, safe, and compatible with fMRI. Magn Reson Med, 2016. © 2016 International Society for Magnetic Resonance in Medicine.

Studies examining the association of anogenital distance (AGD), a biomarker of prenatal androgen exposure, with sexual development in children are lacking. To assess the association between AGD measures and reproductive outcomes, including puberty onset, testicular volume, reproductive hormone levels, and urogenital malformations in boys aged 9-11 years. A cross-sectional study was conducted among children belonging to the Spanish Environment and Childhood (INMA) Project, a population-based birth cohort study. The present sample included 279 boys for whom data were available on AGD, pubertal stage, testicular volume, and relevant covariates. Out of the boys with AGD data, 187 provided a blood sample for hormone analysis. AGD was measured from the center of the anus to the base of the scrotum. Pubertal development was assessed according to Tanner stage of genital development (G1-G5), and testicular volume was measured with an orchidometer. After adjusting for potential confounders, logistic regression analysis showed that AGD was positively associated with testicular volume but not with Tanner stage (>G1 vs. G1), serum hormone levels, or undescended testis. Regardless of their age, body mass index, and Tanner stage (G1 or >G1), boys with longer AGD showed increased odds of a testicular volume >3 mL (OR = 1.06, 95%CI = 1.00-1.19 per 10% increment in AGD; and OR = 3.14, 95%CI = 0.99-9.94 for AGD >42 mm vs. G1 vs. G1), serum hormone levels, or undescended testis. Regardless of their age, body mass index, and Tanner stage (G1 or >G1), boys with longer AGD showed increased odds of a testicular volume >3 mL (OR = 1.06, 95%CI = 1.00-1.19 per 10% increment in AGD; and OR = 3.14, 95%CI = 0.99-9.94 for AGD >42 mm vs. G1), boys with longer AGD showed increased odds of a testicular volume >3 mL (OR = 1.06, 95%CI = 1.00-1.19 per 10% increment in AGD; and OR = 3.14, 95%CI = 0.99-9.94 for AGD >42 mm vs. 3 mL (OR = 1.06, 95%CI = 1.00-1.19 per 10% increment in AGD; and OR = 3.14, 95%CI = 0.99-9.94 for AGD >42 mm vs. 42 mm vs. Longer AGD was associated with testicular growth, an indicator of gonadarche, but not with other reproductive outcomes. Although AGD was positively associated with testicular volume, it remains unclear whether AGD predicts testis size at puberty or is related to puberty onset.

This work presents the dynamic study of the plantar pressure in a group of 15 pregnant women. An instrumented insoles (ECnsole) developed by the research group were used in order to measure the plantar pressure distribution. A questionnaire that described their perception of the back pain were filled by the participants. This test were repeated in weeks 12, 20 and 32 of pregnancy. From our preliminary results, the centre pressure in the Y-axis in both foot were slightly displaced towards the heel in week test 20 and 32, and it agrees with the onset of back pain in pregnant women.

ObjectiveThyroid hormones (THs) are crucial for the correct maturation of the CNS and the neurodevelopment of the child. We aimed to investigate the association of TSH and free thyroxine (FT4) levels with cognitive functioning in children from the INMA-Granada cohort studied during their follow-up at the age of 9–11 years.DesignWe evaluated 300 children from the original cohort, which comprised 668 eligible mother–son pairs recruited at birth from 2000 to 2002 in Granada (Spain).MethodsFT4 and TSH concentrations were measured, and cognitive development was assessed using neuropsychological tests (n=187). Children with chronic disease related to thyroid function and/or cognitive development were excluded.ResultsMedian TSH and FT4 levels were 3.1 μIU/ml and 1.2 ng/dl respectively. In multivariable regression analyses adjusted for maternal and child characteristics, children with TSH levels in the top tertile had worse verbal comprehension and immediate and long-term recall. Children with FT4 levels in the top tertile had better attention and lower impulsivity and were at a lower risk of scoring below the 20th percentile in intelligence quotient (OR=0.24; 95% CI=0.08–0.74; P=0.013) and in abstract reasoning ability (OR=0.28; 95% CI=0.09–0.88; P=0.029).ConclusionOur findings indicate that circulating THs and TSH may in the top tertile have an impact on cognitive functions; thus, higher TSH slightly but significantly increased the risk of a lower score in certain neuropsychological tests.

To describe the overall and disease-free survival at five and ten years after breast cancer diagnosis in women from a previous case-control study, and establish related prognostic factors.We followed up 202 patients diagnosed between 1996 and 1998 in three public hospitals in Granada and Almeria provinces in Spain. Survival rates were calculated using the Kaplan and Meier method, and the Cox proportional hazards model was applied to identify the most significant variables contributing to survival.Mean age at diagnosis was 54.27 ± 10.4 years. Mean follow-up for overall survival was 119.91 months (95%CI 113.65-126.17); the five-year survival rate was 83.9% (95%CI: 78.13-89.66) and the ten-year rate was 71% (95% CI: 63.25-78.74). Mean follow-up for disease-free survival was 118.75 months (95%CI 111.86-125.65); the five-year disease-free survival rate was 81% (95% CI: 74.52-87.47) and the ten-year rate was 71.3% (95% CI: 63.33-79.26). The mortality rate of the study population was 33.17%.Disease characteristics are similar in our population to those in other Spanish and European regions, while the overall survival is higher than the mean rate during the same period in Europe (5-yr rate of 79%) and similar to that in Spain (83%).

Objective: To characterize the exposure to electric fields and magnetic fields of non-ionizing radiation in the electromagnetic spectrum (15 Hz to 100 kHz) in the dwellings of children from the Spanish Environment and Childhood-“INMA” population-based birth cohort. Methodology: The study sample was drawn from the INMA-Granada cohort. Out of 300 boys participating in the 9–10 year follow-up, 123 families agreed to the exposure assessment at home and completed a specific ad hoc questionnaire gathering information on sources of non-ionizing radiation electric and magnetic fields inside the homes and on patterns of use. Long-term indoor measurements were carried out in the living room and bedroom. Results: Survey data showed a low exposure in the children's homes according to reference levels of the International Commission on Non-Ionizing Radiation Protection but with large differences among homes in mean and maximum values. Daytime electrostatic and magnetic fields were below the quantification limit in 78.6% (92 dwellings) and 92.3% (108 dwellings) of houses, with an arithmetic mean value (± standard deviation) of 7.31±9.32 V/m and 162.30±91.16 nT, respectively. Mean magnetic field values were 1.6 lower during the night than the day. Nocturnal electrostatic values were not measured. Exposure levels were influenced by the area of residence (higher values in urban/semi-urban versus rural areas), type of dwelling, age of dwelling, floor of the dwelling, and season. Conclusion: Given the greater sensitivity to extremely low-frequency electromagnetic fields of children and following the precautionary principle, preventive measures are warranted to reduce their exposure., This work was supported by the Spanish Ministry of Health (CIBERESP and FIS PI11/0610) and the Andalusia Regional Government, Council of Innovation, Science and Enterprise (Excellence Project P09-CTS-5488) and Council of Health (SAS PI-0675-2010).
