RESUMO

During female lifetime and pregnancy, inflammation and cellular senescence are implicated in physiological processes, from ovulation and menstruation, to placental homeostasis and delivery. Several lifestyles, nutritional, and environmental insults, as well as long-lasting pregestational inflammatory diseases may lead to detrimental effects in promoting and sustaining a chronic excessive inflammatory response and inflammaging, which finally contribute to the decay of fertility and pregnancy outcome, with a negative effect on placental function, fetal development, and future health risk profile in the offspring. Maladaptation to pregnancy and obstetric disease may in turn increase maternal inflammaging in a feedback loop, speeding up aging processes and outbreak of chronic diseases. Maternal inflammaging may also impact, through transgenerational effects, on future adult health. Hence, efficacious interventions should be implemented by physicians and healthcare professionals involved in prevention activities to reduce the modifiable factors contributing to the inflammaging process in order to improve public health.

RESUMO

Among 733 pregnant women with HIV followed between 2013 and 2021, only 8 (1.1%) had prior HPV vaccination. One had low-grade squamous intraepithelial lesions [LSIL], and none had HPV type information. Among the 725 non-vaccinated women, 578 (79.7%) had information on cervical cytology. Rate of cytologic abnormalities in this group was 20.6% (0.2% atypical glandular cells of undetermined significance [AGC], 1.7% atypical squamous cells of undetermined significance [ASC-US], 11.1% LSIL, and 7.6% high-grade squamous intraepithelial lesions [HSIL]). Among 56 women with HPV type information, 75.0% carried high risk types, with similar occurrence in women with and without cytologic abnormalities, 30.4% had multiple high-risk types, and 75.9% carried at least one of the types included in the currently recommended 9-valent vaccine.

RESUMO

SARS-CoV-2 infection has been related to adverse pregnancy outcomes. A placental role in protecting the fetus from SARS-CoV-2 infection has been documented. Nevertheless, it is still unclear how the placenta is affected in SARS-CoV-2 infection. Here we assessed placental mitochondrial (mt) and oxidative features in COVID-19 and healthy mothers. mtDNA levels, DNA oxidative damage, expression levels of genes involved in antioxidant defenses, mitochondrial dynamics and respiratory chain subunits were investigated in placentas from singleton pregnancies of 30 women with SARS-CoV-2 infection during the third trimester (12 asymptomatic, 18 symptomatic) and 16 controls. mtDNA levels decreased in COVID-19 placentas vs. controls and inversely correlated with DNA oxidative damage, which increased in the symptomatic group. Antioxidant gene expressions decreased in SARS-CoV-2 mothers (CAT, GSS). Symptomatic cases also showed a lower expression of respiratory chain (NDUFA9, SDHA, COX4I1) and mt dynamics (DNM1L, FIS1) genes. Alterations in placental mitochondrial features and oxidative balance in COVID-19-affected mothers might be due to the impaired intrauterine environment, generated by systemic viral effects, leading to a negative vicious circle that worsens placental oxidative stress and mitochondrial efficiency. This likely causes cell homeostasis dysregulations, raising the potential of possible long-term effects.

RESUMO

PURPOSE: To evaluate associations between CD4/CD8 ratio and pregnancy outcomes in women with HIV. METHODS: We evaluated, in a national study of pregnant women with HIV receiving antiretroviral treatment (ART), values of CD4/CD8 ratio at entry in pregnancy, changes between first and third trimester, and possible associations with preterm delivery, low birthweight, and HIV-RNA < 50 copies/ml at third trimester in univariate and multivariate analyses. RESULTS: Among 934 women, 536 (57.4%) were already on ART at conception. CD4/CD8 ratio (baseline value 0.570) increased significantly between the first and third trimesters, particularly in women who started ART in pregnancy (+ 0.163, vs. + 0.036 in women already on treatment). The rate of CD4/CD8 ratio normalization, defined by achieving a ratio ≥ 1 at the third trimester, was 13.2%. In multivariable analyses, women who entered pregnancy with a CD4/CD8 ratio < 0.3, compared to women with ratio ≥ 1, were almost four-times less likely to have third-trimester HIV-RNA < 50 copies/ml (AOR 0.258, 95%CI 0.111-0.601), and more than twice as likely to have preterm delivery (AOR 2.379, 95%CI 1.082-5.232). For preterm delivery, also a baseline CD4/CD8 ratio between 0.3 and 0.45 was significantly associated with an increased risk (AOR: 3.415, 95%CI 1.690-6.900). CONCLUSION: We described for the first time independent associations of low CD4/CD8 ratio with preterm delivery and HIV-RNA suppression.

RESUMO

Overweight and obesity during pregnancy have been associated with increased birth weight, childhood obesity, and noncommunicable diseases in the offspring, leading to a vicious transgenerational perpetuating of metabolic derangements. Key components in intrauterine developmental programming still remain to be identified. Obesity involves chronic low-grade systemic inflammation that, in addition to physiological adaptations to pregnancy, may potentially expand to the placental interface and lead to intrauterine derangements with a threshold effect. Animal models, where maternal inflammation is mimicked by single injections with lipopolysaccharide (LPS) resembling the obesity-induced immune profile, showed increased adiposity and impaired metabolic homeostasis in the offspring, similar to the phenotype observed after exposure to maternal obesity. Cytokine levels might be specifically important for the metabolic imprinting, as cytokines are transferable from maternal to fetal circulation and have the capability to modulate placental nutrient transfer. Maternal inflammation may induce metabolic reprogramming at several levels, starting from the periconceptional period with effects on the oocyte going through early stages of embryonic and placental development. Given the potential to reduce inflammation through inexpensive, widely available therapies, examinations of the impact of chronic inflammation on reproductive and pregnancy outcomes, as well as preventive interventions, are now needed.

RESUMO

Obesity is becoming pandemic and is associated with impaired reproductive potential. Oxidative stress, low-grade chronic inflammation and mitochondrial dysfunctions, which characterize obesity, strongly affect oocyte environment and function. Supplementation with antioxidant and anti-inflammatory compounds has been suggested to improve fertility. Here we evaluated the effect of α-lipoic acid and myo-inositol supplementation on the oocyte environment of infertile obese women. Nineteen normal-weight and twenty-three obese women, infertile for non-ovarian reasons, were recruited. For two months before ovarian stimulation, all women received 400 µg/die folic acid, whereas 15 obese were additionally supplemented with 800 mg α-lipoic acid, 2 g myo-inositol/die. Antioxidant capacity was measured in follicular fluid by enzymatic assay; mitochondrial DNA (mtDNA) content and mRNA levels of two respiratory chain subunits were analyzed in granulosa cells by Real-time PCR. Pregnancy rate was similar between normal-weight and treated obese, and lower in untreated obese patients. Supplemented women showed significantly higher antioxidant levels in follicular fluid compared to the two groups taking only folic acid. Conversely, granulosa cells mtDNA content was decreased in treated and higher in untreated obese patients compared to normal-weight women, suggesting mtDNA increases to compensate for oxidative-stress damages. Reduced expression of respiratory subunits in untreated obese may confirm mitochondria impairment. Interestingly, mtDNA levels inversely correlated to both total and metaphase II oocyte number. In this preliminary study, combined supplementation of α-lipoic acid and myo-inositol in infertile obese women was associated with amelioration in the oxidative status of the oocyte environment, possibly contributing to a higher pregnancy rate.

RESUMO

This study investigated the associations between maternal adherence to a healthy diet, first trimester placental markers, and pregnancy outcome. Singleton spontaneous pregnancies were enrolled at 11+0-13+6 gestational weeks in a prospective cohort study. A nutritional score (0-10) measuring the adherence to a healthy diet was calculated. A transabdominal ultrasound scan for placental marker assessment was performed (uterine artery (UtA) doppler, placental volume). Biochemical placental markers were recorded (Pregnancy Associated Plasma Protein A (PAPP-A), free ß- Human Chorionic Gonadotropin (HCG)). Birth outcomes were obtained from medical records. Associations between the maternal nutritional score, first trimester placental markers, and pregnancy outcome were investigated by using multi-adjusted general linear models. In total, 112 pregnancies were enrolled with a median nutritional score of 7 (range 3-10). Median gestational age at birth was 277 days (range 203-296). The nutritional score was positively associated with PAPP-A concentrations, whereas a negative association was detected with the UtA mean pulsatility index and placental volume. A positive association was detected between nutritional score and gestational age at birth. This study demonstrates that a first trimester nutritional score as a measure of adherence to a healthy diet is significantly associated with early biochemical and ultrasound markers of placental development, with further association with gestational age at birth.

RESUMO

OBJECTIVE: To investigate the clinical evolution of coronavirus disease 2019 (COVID-19) in hospitalized pregnant women and potential factors associated with severe maternal outcomes. METHODS: We designed a prospective multicenter cohort study of pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection who were admitted to 12 Italian maternity hospitals between February 23 and March 28, 2020. Clinical records, laboratory and radiologic examinations, and pregnancy outcomes were collected. A subgroup of patients with severe disease was identified based on intensive care unit (ICU) admission, delivery for respiratory compromise, or both. RESULTS: Seventy-seven patients were included, 14 of whom had severe disease (18%). Two thirds of the patients in the cohort were admitted during the third trimester, and 84% were symptomatic on admission. Eleven patients underwent urgent delivery for respiratory compromise (16%), and six were admitted to the ICU (8%). One woman received extracorporeal membrane oxygenation; no deaths occurred. Preterm delivery occurred in 12% of patients, and nine newborns were admitted to the neonatal intensive care unit. Patients in the severe subgroup had significantly higher pregestational body mass indexes (BMIs) and heart and respiratory rates and a greater frequency of fever or dyspnea on admission compared with women with a nonsevere disease evolution. CONCLUSION: In our cohort, one in five women hospitalized with COVID-19 infection delivered urgently for respiratory compromise or were admitted to the ICU. None, however, died. Increased pregestational BMI and abnormal heart and respiratory rates on admission were associated with severe disease.

RESUMO

INTRODUCTION: The role of ultrasound imaging in urogynecology is not defined. Significant developments in visualization techniques and interpretation of images allowed to study structures of the lower genitourinary tract and pelvic floor. EVIDENCE ACQUISITION: PubMed and Scopus database were searched for publications on the following item: stress urinary incontinence, ultrasound, perineal ultrasound and preoperative and postoperative assessment. EVIDENCE SYNTHESIS: The role of ultrasound in urogynecology could be helpful in diagnosing of urinary incontinence and urethral hypermobility, to document pelvic floor anatomy and to assess anatomic and functional changes before and after surgery. CONCLUSIONS: Ultrasound could be an important step during preoperative and post-operative assessment of patients affected by stress urinary incontinence.

RESUMO

INTRODUCTION: This study investigates the hypothesis that placenta works differently in oocyte donation (OD) compared to spontaneous pregnancies. To verify this hypothesis we examine the first trimester maternal serum levels of free ß-hCG and pregnancy-associated plasma protein-A (PAPP-A). Then we evaluated for potential differences of Down syndrome screening between OD pregnancies, in vitro fertilization/intracytoplasmic sperm injection pregnancies with autologous oocytes (IVF/ICSI) and spontaneous pregnancies. METHODS: We analyze 13624 spontaneously conceived pregnancies (Controls), 171 oocyte donation pregnancies (OD IVF/ICSI) and 76 IVF pregnancies with autologous oocytes (Autologous IVF/ICSI). Furthermore, we collect a cohort of 802 spontaneously conceived age-matched pregnancies, in order to evaluate how older uteri contribute to explain the changes in markers concentrations (Age-matched controls We compare the multiples of the median (MoM) of free ß-hCG and PAPP-A and nuchal translucency. RESULTS: Free ß-hCG levels are significantly higher both in OD IVF/ICSI pregnancies (1.44 ± 1.06 MoM) and Autologous IVF/ICSI (1.48 ± 1.02 MoM) compared to Controls (1.15 ± 0.84 MoM; p < 0.05) and Age-matched Controls (1.18 ± 0.98 MoM; p < 0.05). PAPP-A levels do not significantly differ among the four groups. Significantly lower nuchal translucency is detected in Controls (1.41 ± 0.36 mm) compared to OD IVF/ICSI (1.46 ± 0.44 mm; p < 0.05), in Autologous IVF/ICSI (1.51 ± 0.34 mm; p < 0.05) and Age-matched Controls (1.44 ± 0.42 mm; p < 0.05). DISCUSSION: Oocyte donation pregnancies (OD IVF/ICSI) are significantly related to altered maternal serum placenta marker levels. These alterations might be due to the IVF technique.
