(2024) BATISTA, Patricia Andrade; OLIVEIRA, Claudia de; COSTA, Rafaela Alkmin da; FRANCISCO, Rossana Pulcineli Vieira; CABAR, Fabio Roberto
Introduction: Pregnancy and diabetes mellitus promote several musculoskeletal changes predisposing this population to complaints of Lower Back (LB) and Pelvic Pain (PP). Objective: To assess the frequency of LB and PP and associated factors in type 1 Diabetic (DM1) pregnant women. Method: An observational analytical cross-sectional study. Thirty-six pregnant women with DM1 were evaluated through a postural assessment with a focus on pelvic positioning and what patients reported. The associated factors were assessed using the State-Trait Anxiety Inventory (STAI), the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Female Sexual Function Index (FSFI). Results: The frequency of LB and PP was 55.6 % and 30.6 %, respectively. The presence of anxiety was not associated with a higher prevalence of pain. The incidence of sexual dysfunctions was higher in the GD. DM1 duration had a mean of 14.9 years (+/- 8.2 SD) in the GD and 9.0 years (+/- 6.9 SD) in the GSD, which was statistically significant (p <= 0.050). In the multiple binary regression analysis for the occurrence of pain, the independent factor was DM1 duration >= 17 years (OR = 11.2; 95 % CI = 1.02-124.75). The association between DM1 duration >= 17 years and being overweight showed a probability of 95 % for the studied population in the analysis of the probabilities of occurrence of the pain event. Conclusion: There was a high frequency of LB and PP related to pregnancy in DM1 pregnant women in the second trimester of pregnancy. The incidence of sexual dysfunction and DM1 duration >= 17 years increases the chance that DM1 pregnant women will experience pain. There was no association between anxiety. urinary incontinence and pain in DM1 pregnant women.

Visual Analogue Scale Cut-off Point of Seven Represents Poor Quality of Life in Patients with Endometriosis
(2024) ANDRES, Marina Paula; RICCIO, Luiza Gama Coelho; ABRAO, Henrique Mendonca; MANZINI, Mariana Simionato; BRAGA, Lais; ABRAO, Mauricio Simoes
Establishing objective criteria to assess endometriosis symptoms is crucial in defining therapeutic strategies. The visual analogue scale (VAS) is the most used system to enhance the accuracy and reduce the subjectivity of pain assessment, and symptoms of endometriosis are considered severe when the VAS score is >= 7 cm. Pain symptoms can significantly impact patients' quality of life, resulting in psychological and social distress. The aim of this study is to evaluate whether a VAS cut-off point of 7 cm for each pain symptom correlates with a diminished quality of life in women with endometriosis. This retrospective study included 1129 patients who underwent surgical treatment for endometriosis. Dysmenorrhea, acyclic pelvic pain, deep dyspareunia, dyschezia, and dysuria were assessed using a 0-10 cm VAS. The Short Form-36 (SF-36) questionnaire was employed to evaluate the quality of life 6 months prior to surgery. Dysmenorrhea was the most prevalent symptom reported in 93.6% of cases, with a mean VAS of 7.6 cm. The quality of life reported was reduced in most patients, with domain scores ranging from 49.4 to 80.1. The mean SF-36 scores in all domains were significantly lower in patients with severe pain (VAS score >= 7 cm) compared to those with mild to moderate pain (VAS < 7 cm). This trend was observed across all evaluated pain symptoms. Our research demonstrates that the prevalent VAS cut-off point for establishing severe pain symptoms in endometriosis (VAS >= 7 cm) accurately represents the negative impact of the disease on women's quality of life, as assessed via the SF-36 questionnaire.

Introduction The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency.Methods At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output.Results Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19.Discussion Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.
Adverse Perinatal Outcomes among Adolescent Pregnant Women Living with HIV: A Propensity-Score-Matched Study
(2023) OSMUNDO JUNIOR, G. D. S.; CABAR, F. R.; PERES, S. V.; WAISSMAN, A. L.; GALLETTA, M. A. K.; FRANCISCO, R. P. V.
HIV infection and adolescent pregnancy are known to increase the risk of adverse perinatal outcomes. However, data are limited concerning the outcomes of pregnancies among adolescent girls living with HIV. This retrospective propensity-score matched study aimed to compare adverse perinatal outcomes in adolescent pregnant women living with HIV (APW-HIV-positive) with HIV-negative adolescent pregnant women (APW-HIV-negative) and adult pregnant women with HIV (PW-HIV). APW-HIV-positive were propensity-score matched with APW-HIV-negative and PW-HIV. The primary endpoint was a composite endpoint of adverse perinatal outcomes, comprising preterm birth and low birth weight. There were 15 APW-HIV-positive and 45 women in each control group. The APW-HIV-positive were aged 16 (13–17) years and had had HIV for 15.5 (4–17) years, with 86.7% having perinatally acquired HIV. The APW-HIV-positive had higher rates of perinatally acquired HIV infection (86.7 vs. 24.4%, p < 0.001), a longer HIV infection time (p = 0.021), and longer exposure to antiretroviral therapy (p = 0.034) compared with the PW-HIV controls. The APW-HIV-positive had an almost five-fold increased risk of adverse perinatal outcomes compared with healthy controls (42.9% vs. 13.3%, p = 0.026; OR 4.9, 95% CI 1.2–19.1). The APW-HIV-positive and APW-HIV-negative groups had similar perinatal outcomes.
Skin-sparing mastectomy for the treatment of breast cancer
(2023) MOTA, B. S.; BEVILACQUA, J. L. B.; BARRETT, J.; RICCI, M. D.; MUNHOZ, A. M.; FILASSI, J. R.; BARACAT, E. C.; RIERA, R.
Background: Skin-sparing mastectomy (SSM) is a surgical technique that aims to maximize skin preservation, facilitate breast reconstruction, and improve cosmetic outcomes. Despite its use in clinical practice, the benefits and harms related to SSM are not well established. Objectives: To assess the effectiveness and safety of skin-sparing mastectomy for the treatment of breast cancer. Search methods: We searched Cochrane Breast Cancer's Specialized Register, CENTRAL, MEDLINE, Embase, LILACS, the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP), and ClinicalTrials.gov on 9 August 2019. Selection criteria: Randomized controlled trials (RCTs), quasi-randomized or non-randomized studies (cohort and case-control) comparing SSM to conventional mastectomy for treating ductal carcinoma in situ (DCIS) or invasive breast cancer. Data collection and analysis: We used standard methodological procedures expected by Cochrane. The primary outcome was overall survival. Secondary outcomes were local recurrence free-survival, adverse events (including overall complications, breast reconstruction loss, skin necrosis, infection and hemorrhage), cosmetic results, and quality of life. We performed a descriptive analysis and meta-analysis of the data. Main results: We found no RCTs or quasi-RCTs. We included two prospective cohort studies and twelve retrospective cohort studies. These studies included 12,211 participants involving 12,283 surgeries (3183 SSM and 9100 conventional mastectomies). It was not possible to perform a meta-analysis for overall survival and local recurrence free-survival due to clinical heterogeneity across studies and a lack of data to calculate hazard ratios (HR). Based on one study, the evidence suggests that SSM may not reduce overall survival for participants with DCIS tumors (HR 0.41, 95% CI 0.17 to 1.02; P = 0.06; 399 participants; very low-certainty evidence) or for participants with invasive carcinoma (HR 0.81, 95% CI 0.48 to 1.38; P = 0.44; 907 participants; very low-certainty evidence). For local recurrence-free survival, meta-analysis was not possible, due to high risk of bias in nine of the ten studies that measured this outcome. Informal visual examination of effect sizes from nine studies suggested the size of the HR may be similar between groups. Based on one study that adjusted for confounders, SSM may not reduce local recurrence-free survival (HR 0.82, 95% CI 0.47 to 1.42; P = 0.48; 5690 participants; very low-certainty evidence). The effect of SSM on overall complications is unclear (RR 1.55, 95% CI 0.97 to 2.46; P = 0.07, I2 = 88%; 4 studies, 677 participants; very low-certainty evidence). Skin-sparing mastectomy may not reduce the risk of breast reconstruction loss (RR 1.79, 95% CI 0.31 to 10.35; P = 0.52; 3 studies, 475 participants; very low-certainty evidence), skin necrosis (RR 1.15, 95% CI 0.62 to 2.12; P = 0.22, I2 = 33%; 4 studies, 677 participants; very low-certainty evidence), local infection (RR 2.04, 95% CI 0.03 to 142.71; P = 0.74, I2 = 88%; 2 studies, 371 participants; very low-certainty evidence), nor hemorrhage (RR 1.23, 95% CI 0.47 to 3.27; P = 0.67, I2 = 0%; 4 studies, 677 participants; very low-certainty evidence). We downgraded the certainty of the evidence due to the risk of bias, imprecision, and inconsistency among the studies. There were no data available on the following outcomes: systemic surgical complications, local complications, explantation of implant/expander, hematoma, seroma, rehospitalization, skin necrosis with revisional surgery, and capsular contracture of the implant. It was not possible to perform a meta-analysis for cosmetic and quality of life outcomes due to a lack of data. One study performed an evaluation of aesthetic outcome after SSM: 77.7% of participants with immediate breast reconstruction had an overall aesthetic result of excellent or good versus 87% of participants with delayed breast reconstruction. Authors' conclusions: Based on very low-certainty evidence from observational studies, it was not possible to draw definitive conclusions on the effectiveness and safety of SSM for breast cancer treatment. The decision for this technique of breast surgery for treatment of DCIS or invasive breast cancer must be individualized and shared between the physician and the patient while considering the potential risks and benefits of available surgical options.
Vaginal progesterone for preventing preterm birth and adverse perinatal outcomes in twin gestations: a systematic review and meta-analysis
(2023) CONDE-AGUDELO, Agustin; ROMERO, Roberto; REHAL, Anoop; BRIZOT, Maria L.; SERRA, Vicente; FONSECA, Eduardo Da; CETINGOZ, Elcin; SYNGELAKI, Argyro; PERALES, Alfredo; HASSAN, Sonia S.; NICOLAIDES, Kypros H.
OBJECTIVE: To evaluate the efficacy of vaginal progesterone for the prevention of preterm birth and adverse perinatal outcomes in twin gestations.DATA SOURCES: MEDLINE, Embase, LILACS, and CINAHL (from their inception to January 31, 2023), Cochrane databases, Google Scholar, bibliographies, and conference proceedings.STUDY ELIGIBILITY CRITERIA: Randomized controlled trials that compared vaginal progesterone to placebo or no treatment in asymptomatic women with a twin gestation.METHODS: The systematic review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. The primary outcome was preterm birth <34 weeks of gestation. Secondary outcomes included adverse perinatal outcomes. Pooled relative risks with 95% confidence intervals were calculated. We assessed the risk of bias in each included study, heterogeneity, publication bias, and quality of evidence, and performed subgroup and sensitivity analyses.RESULTS: Eleven studies (3401 women and 6802 fetuses/infants) fulfilled the inclusion criteria. Among all twin gestations, there were no significant differences between the vaginal progesterone and placebo or no treatment groups in the risk of preterm birth <34 weeks (relative risk, 0.99; 95% confidence interval, 0.84-1.17; high-quality evidence), <37 weeks (relative risk, 0.99; 95% confidence interval, 0.92-1.06; high-quality evidence), and <28 weeks (relative risk, 1.00; 95% confidence interval, 0.64-1.55; moderate-quality evidence), and spontaneous preterm birth <34 weeks of gestation (relative risk, 0.97; 95% confidence interval, 0.80-1.18; high-quality evidence). Vaginal progesterone had no significant effect on any of the perinatal outcomes evaluated. Subgroup analyses showed that there was no evidence of a different effect of vaginal progesterone on preterm birth <34 weeks of gestation related to chorionicity, type of conception, history of spontaneous preterm birth, daily dose of vaginal progesterone, and gestational age at initiation of treatment. The frequencies of preterm birth <37, <34, <32, <30, and <28 weeks of gestation and adverse perinatal outcomes did not significantly differ between the vaginal progesterone and placebo or no treatment groups in unselected twin gestations (8 studies; 3274 women and 6548 fetuses/infants). Among twin gestations with a transvaginal sonographic cervical length <30 mm (6 studies; 306 women and 612 fetuses/infants), vaginal progesterone was associated with a significant decrease in the risk of preterm birth occurring at <28 to <32 gestational weeks (relative risks, 0.48-0.65; moderate-to high-quality evidence), neonatal death (relative risk, 0.32; 95% confidence interval, 0.11-0.92; moderate-quality evidence), and birthweight <1500 g (relative risk, 0.60; 95% confidence interval, 0.39-0.88; high-quality evidence). Vaginal progesterone significantly reduced the risk of preterm birth occurring at <28 to <34 gestational weeks (relative risks, 0.41-0.68), composite neonatal morbidity and mortality (relative risk, 0.59; 95% confidence interval, 0.33-0.98), and birthweight <1500 g (relative risk, 0.55; 95% confidence interval, 0.33-0.94) in twin gestations with a transvaginal sonographic cervical length <= 25 mm (6 studies; 95 women and 190 fetuses/infants). The quality of evidence was moderate for all these outcomes. CONCLUSION: Vaginal progesterone does not prevent preterm birth, nor does it improve perinatal outcomes in unselected twin gestations, but it appears to reduce the risk of preterm birth occurring at early gestational ages and of neonatal morbidity and mortality in twin gestations with a sonographic short cervix. However, more evidence is needed before recommending this intervention to this subset of patients.

Association of intrauterine synechiae with pituitary gonadotrophin pulse patterns: A pilot study
(2023) GIANFALDONI, Arlete; ROA, Cristiane; SIMOES, Ricardo dos Santos; BARACAT, Maria Candida P.; FONSECA, Angela Maggio da; BAGNOLI, Vicente Renato; SOPRESO, Isabel Cristina Esposito; RIVAS, Fernando Wladimir Silva; MONTELEONE, Pedro; BARACAT, Edmund C.; JR, Jose Maria Soares
BackgroundIntrauterine synechiae (IS) is an acquired uterine condition that occurs when scar tissues (adhesions) form within the uterus and/or cervix, causing menstrual disturbance. However, approximately 50% of patients with IS are refractory to treatment. Therefore, other endocrine disturbances, such as gonadotropin disturbance, may affect treatment success.Study aimTo analyze gonadotropin levels in women with and without IS.MethodsTen women with refractory IS experiencing amenorrhea since at least 6 months and nine with normal menstrual cycles (control group) were included in this study. Blood sample were collected every 10 minutes during a 4-h period. The serial ultrasound was performed in both groups for evaluating the cycle phase. Blood was collected when the follicles size was between 5-10 mm. Serum LH, FSH, progesterone and estradiol concentrations were measured. To detect LH and FSH pulses, the technique proposed by Santen and Bardin was adopted; therefore, one pulse was defined as a 20% increase in the concentrations as to the preceding point, followed by an important decrease.ResultsNo differences were observed between the study groups at baseline. Estradiol levels were lower in the IS group than in the control group, but the difference was not statistically significant. During the first hour of monitoring, cumulative FSH pulsatile frequency of IS group was lower than one of control.ConclusionOur data suggest that the estradiol levels of IS participants are lower than those of women with normal menstrual cycle. The role of this finding in the physiology of uterine synechiae requires further investigation.

(2023) MENEZESDASILVA, Glaucia Mara; VEIGA, Eduardo Carvalho de Arruda; SIMOES, Manuel Jesus; SIMOES, Ricardo Santos; SHIROMA, Marcos Eiji; BARACAT, Maria Candida Pinheiro; CAVALCANTI, Givanna Santos; SOARES JUNIOR, Jose Maria; BARACAT, Edmund Chada
Introduction: The CA1 region of the hippocampus has an important role in learning and memory. It has been shown that estrogen deficiency may reduce the synaptic density in the region and that hormone replacement ther-apy may attenuate the reduction. Objectives: This study aimed to evaluate the effects of estrogen and raloxifene on the synaptic density profile in the CA1 region of the hippocampus in ovariectomized rats.Methods: Sixty ovariectomized three-month-old virgin rats were randomized into six groups (n = 10). Treatments started either three days (early treatment) or sixty days (late treatment) after ovariectomy. The groups received propylene glycol vehicle (0.5 mL/animal/day), equine conjugated estrogens (50 mu g/animal/day), or raloxifene (3 mg/kg/day) either early or late after ovariectomy. The drugs were administered orally by gavage for 30 days. At the end of the treatments, the animals were anesthetized and transcardially perfused with ether and saline solu-tion. The brains were removed and prepared for analysis under transmission electron microscopy and later fixed. Results: Results showed a significant increase in the synaptic density profile of the hippocampal CA1 region in both the early estrogen (0.534 +/- 0.026 mu/m2) and the early raloxifene (0.437 +/- 0.012 mu/m2) treatment groups compared to the early or late vehicle-treated control groups (0.338 +/- 0.038 mu/m2 and 0.277 +/- 0.015 mu/m2 respectively).Conclusions: The present data suggest that the raloxifene effect may be lower than that of estrogen, even early or late treatment, on synaptic density in the hippocampus.
Locally advanced breast cancer: breast-conserving surgery and other factors linked to overall survival after neoadjuvant treatment
(2023) NOBREGA, Gabriela Bezerra; MOTA, Bruna Salani; FREITAS, Gabriela Boufelli de; MAESAKA, Jonathan Yugo; MOTA, Rosa Maria Salani; GONCALVES, Rodrigo; TRINCONI, Angela Francisca; RICCI, Marcos Desiderio; PIATO, Jose Roberto; SOARES-JR, Jose Maria; BARACAT, Edmund Chada; FILASSI, Jose Roberto
Background Recent data suggest that breast-conserving surgery (BCS) may positively impact overall survival (OS) in early breast cancer. However, the role of BCS in locally advanced breast cancer (LABC) following neoadjuvant therapy (NAT) remains uncertain.Methods We conducted a retrospective cohort study involving 530 LABC patients who underwent surgery after NAT between 2010 and 2015. Outcomes examined included OS, distant recurrence rates (DRR), and loco-regional recurrence rates (LRRs).Results Among the 927 breast cancer patients who received NAT, 530 were eligible for our study. Of these, 24.6% underwent BCS, while 75.4% underwent mastectomy (MS). The median follow-up duration was 79 months. BCS patients exhibited a higher pathological complete response (PCR) rate compared to those who underwent MS (22.3% vs. 10%, p < 0.001). The 6-year OS rates for BCS and MS were 81.5% and 62%, respectively (p < 0.000). In multivariate OS analysis, MS was associated with worse outcomes (OR 1.678; 95% CI 1.069-2.635; p = 0.024), as was body mass index (BMI) (OR 1.031; 95% CI 1.006-1.058; p = 0.017), and stage IIIB or IIIC (OR 2.450; 95% CI 1.561-3.846; p < 0.000). Conversely, PCR (OR 0.42; 95% CI 0.220-0.801; p = 0.008) was associated with improved survival. DRR was significantly lower in BCS (15.4%) compared to MS (36.8%) (OR 0.298; 95% CI 0.177-0.504). LRRs were comparable between BCS (9.2%) and MS (9.5%) (OR 0.693; 95% CI 0.347-1.383).Conclusion Our findings suggest that BCS is oncologically safe, even for patients with large lesions, and is associated with superior OS rates compared to MS. Additionally, lower BMI, lower pretreatment stage, and achieving PCR were associated with improved survival outcomes.
Does bisphenol A (BPA) participates in the pathogenesis of Polycystic Ovary Syndrome (PCOS)?
(2023) URBANETZ, Lorena Ana Mercedes Lara; JR, Jose Maria Soares; MACIEL, Gustavo Arantes Rosa; SIMOES, Ricardo dos Santos; BARACAT, Maria Candida Pinheiro; BARACAT, Edmund Chada
PCOS is an endocrine disorder characterized by chronic anovulation, hyperandrogenism, and polycystic ovaries. Its etiology is uncertain. It is debated whether BPA would be a component of the environmental factor in the etiology of PCOS. Contamination by BPA can occur from food packaging (exposure during the diet) and through skin absorption and/or inhalation. It can be transferred to the fetus via the placenta or to the infant via breast milk, and it can be found in follicular fluid, fetal serum, and amniotic fluid. The phenolic structure of BPA allows it to interact with Estrogen Receptors (ERs) through genomic signaling, in which BPA binds to nuclear ER alpha or Er beta, or through nongenomic signaling by binding to membrane ERs, prompting a rapid and intense response. With daily and constant exposure, BPA's tendency to bioaccumulate and its ability to activate nongenomic signaling pathways can alter women's metabolic and reproductive function, leading to hyperandrogenism, insulin resistance, obesity, atherogenic dyslipidemia, chronic inflammatory state, and anovulation and favoring PCOS. The harmful changes caused by BPA can be passed on to future generations without the need for additional exposure because of epigenetic modifications. Not only high BPA levels can produce harmful effects, but at low levels, BPA may be harmful when exposure occurs during the most vulnerable periods, such as the fetal and neonatal periods, as well as during the prepubertal age causing an early accumulation of BPA in the body. Learning how BPA participates in the pathogenesis of PCOS poses a challenge and further studies should be conducted.

(2023) JR, Jose Maria Soares; HAYASHIDA, Sylvia Asaka Yamashita; MARCONDES, Jose Antonio Miguel; MACIEL, Gustavo Arantes Rosa; BARCELLOS, Cristiano Roberto Grimaldi; MAFFAZIOLI, Giovana De Nardo; MONTEIRO, Karla Krislaine Alves Costa; TURRI, Jose Antonio Orellana; AZZIZ, Ricardo; BARACAT, Edmund Chada
Background: We followed polycystic ovary syndrome (PCOS) women with metabolic syndrome (MS) over a six-year treatment period and evaluated the influence of PCOS phenotypes on MS and on the risk for type 2 diabetes mellitus (T2DM). Methods: This was an observational study of 457 PCOS women, whose demographic, clinical, hormonal, and metabolic data underwent analysis. The PCOS women were divided into four groups per NIH recommendations. Results: After a follow-up of a mean of six years (1-20 years), 310 patients were selected to assess the development of T2DM and MS. The clinical and biochemical parameters, along with the Rotterdam phenotypes, were evaluated. Data were analyzed using Student's t- and the Pearson chi-square tests for data variation and group proportions, respectively. Additionally, multivariate analysis was applied to evaluate the effect of PCOS phenotypes on the risk for MS and T2DM. Patients of the four PCOS phenotypes did not differ in age, body mass index, total testosterone, insulin resistance, and dyslipidemia, but phenotype A patients showed the highest risk for T2DM. A decrease in androgen levels was not followed by an improved metabolic profile; instead, there was a significant increase in the number of T2DM cases. Conclusion: Phenotype A women are at the highest risk for type 2 diabetes mellitus.

(2023) NISHIE, Estela Naomi; OSMUNDO-JUNIOR, Gilmar de Souza; MOHAMED, Samirah Hosney Mahmoud; TANNURI, Ana Cristina Aoun; GIBELLI, Maria Augusta Bento Cicaroni; CARVALHO, Werther Brunow de; PERES, Stela Verzinhasse; FRANCISCO, Rossana Pulcineli Vieira; BRIZOT, Maria de Lourdes
Introduction: Abdominal wall defects (AWD) interfere with postnatal respiratory parameters. We aimed to evaluate lung volume (LV) in fetuses with AWD using three-dimensional (3D) ultrasound (US) and to correlate AWD with the type (omphalocele and gastroschisis) and size of the defect and neonatal morbidity and mortality.Methods: This prospective study included 72 pregnant women with fetuses with AWD and a gestational age <25 weeks. Abdominal volume, 3D US LV, and herniated volume were acquired every 4 weeks up to 33 weeks. LV was compared with normal reference curves and correlated with abdominal and herniated volumes.Results: Omphalocele (p<0.001) and gastroschisis (p<0.001) fetuses had smaller LV than did normal fetuses. LV was positively correlated with abdominal volume (omphalocele, r=0.86; gastroschisis, r=0.88), whereas LV was negatively correlated with omphalocele-herniated volume/abdominal volume (p<0.001, r= -0.51). LV was smaller in omphalocele fetuses that died (p=0.002), were intubated (p=0.02), or had secondary closure (p<0.001). In gastroschisis, a smaller LV was observed in fetuses discharged using oxygen (p=0.002).Discussion/Conclusion: Fetuses with AWD had smaller 3D LV than normal fetuses. Fetal abdominal volume was inversely correlated with LV. In omphalocele fetuses, a smaller LV was associated with neonatal mortality and morbidity.

Background: In recent years, new combined oral contraceptives (COCs) have become available, representing an advance in terms of individualization and compliance by users.Objective: To provide recommendations regarding COCs: formulations, use, efficacy, benefits and safety.Method: For these recommendations, we have used the modified Delphi methodology and carried out a systematic review of studies found in the literature and reviews performed in humans, published in English and Spanish in Pubmed, Medline and advanced medicine and computer networks until the year 2021, using the combination of terms: 'oral contraceptives', 'estroprogestins' and 'combined oral contraceptives'.Results: Regarding the estrogen component, initially switching from mestranol (the pro-drug of ethinylestradiol) to ethinylestradiol (EE) and then reducing the EE dose helped reduce side effects and associated adverse events. Natural estradiol and estradiol valerate are already available and represent a valid alternative to EE. The use of more potent 19-nortestosterone-derived progestins, in order to lower the dose and then the appearance of non-androgenic progestins with different endocrine and metabolic characteristics, has made it possible to individualize the prescription of COC according to the profile of each woman.Conclusion: Advances in the provision of new COCs have improved the risk/benefit ratio by increasing benefits and reducing risks. Currently, the challenge is to tailor contraceptives to individual needs in terms of safety, efficacy, and protection of female reproductive health.
MicroRNA-210-3p Regulates Endometriotic Lesion Development by Targeting IGFBP3 in Baboons and Women with Endometriosis
(2023) KAI, Kentaro; JOSHI, Niraj R.; BURNS, Gregory W.; HRBEK, Samantha M.; VEGTER, Erin L.; OCHOA-BERNAL, Maria Ariadna; SONG, Yong; MOLDOVAN, Genna E.; SEMPERE, Lorenzo F.; MIYADAHIRA, Eduardo H.; SERAFINI, Paulo C.; FAZLEABAS, Asgerally T.
MicroRNAs (miRs) play an important role in the pathophysiology of endometriosis; however, the role of miR-210 in endometriosis remains unclear. This study explores the role of miR-210 and its targets, IGFBP3 and COL8A1, in ectopic lesion growth and development. Matched eutopic (EuE) and ectopic (EcE) endometrial samples were obtained for analysis from baboons and women with endometriosis. Immortalized human ectopic endometriotic epithelial cells (12Z cells) were utilized for functional assays. Endometriosis was experimentally induced in female baboons (n = 5). Human matched endometrial and endometriotic tissues were obtained from women (n = 9, 18-45 years old) with regular menstrual cycles. Quantitative reverse transcript polymerase chain reaction (RT-qPCR) analysis was performed for in vivo characterization of miR-210, IGFBP3, and COL8A1. In situ hybridization and immunohistochemical analysis were performed for cell-specific localization. Immortalized endometriotic epithelial cell lines (12Z) were utilized for in vitro functional assays. MiR-210 expression was decreased in EcE, while IGFBP3 and COL8A1 expression was increased in EcE. MiR-210 was expressed in the glandular epithelium of EuE but attenuated in those of EcE. IGFBP3 and COL8A1 were expressed in the glandular epithelium of EuE and were increased compared to EcE. MiR-210 overexpression in 12Z cells suppressed IGFBP3 expression and attenuated cell proliferation and migration. MiR-210 repression and subsequent unopposed IGFBP3 expression may contribute to endometriotic lesion development by increasing cell proliferation and migration.

Background: Despite the success of interventional coronary reperfusion strategies, morbidity and mortality from acute myocardial infarction are still substantial. Physical exercise is a well-recognized effective nonpharmacological therapy for cardiovascular diseases. Therefore, the objective of this systematic review was to analyze studies in animal models of ischemia-reperfusion in association with physical exercise protocols.Search strategy: Articles published on the topic over a 13-year period (2010-2022) were searched in two databases (PubMed and Google Scholar) using the keywords exercise training, ischemia/reperfusion or ischemia reperfusion injury. Meta-analysis and quality assessment of the studies were performed using the Review Manager 5.3 program.Results: From the 238 articles retrieved from PubMed and 200 from Google Scholar, after screening and eligibility assessment, 26 articles were included in the systematic review and meta-analysis. For meta-analysis comparing the group of previously exercised animals with the non-exercised animals and then submitted to ischemia-reperfusion, the infarct size was significantly decreased by exercise (p < 0.00001). In addition, the group exercised had increased heart-to-body weight ratio (p < 0.00001) and improved ejection fraction as measured by echocardiography (p < 0.0004) in comparison to non-exercised animals.Conclusion: We concluded that the animal models of ischemia-reperfusion indicates that exercise reduce infarct size and preserve ejection fraction, associated with beneficial myocardial remodeling.
