RESUMO

BACKGROUND: Labial adhesions, a frequent gynecological condition in prepubertal girls, occur when the labia minora adhere along the midline. The prevailing hypothesis about their etiology suggests that labial adhesion may occur when the delicate and non-estrogenized labia minora undergo an inflammatory response, triggered by exposure to an irritant environment. Therefore, conservative treatment involves the application of topical estrogen or betamethasone cream. The role of androgens has not been considered yet in the pathophysiology or therapy of this condition. However, some studies have shown that androgen receptors are prevalent in the labia minora and vulvar vestibule. CASE SUMMARY: We present the case of a 29-month-old girl with symptomatic labial adhesions. She was first ineffectively treated with topical estriol, and then she was treated with a galenic cream containing both estriol and testosterone with complete recovery and without side-effects. CONCLUSIONS: Both androgens and estrogens play a significant role in maintaining the physiological trophic state of the vulva and vagina, even during childhood. Topical estriol+testosterone could be considered an alternative treatment for prepubertal labial adhesions refractory to standard topical therapy.

RESUMO

COVID-19 infection is associated with increased risk of pregnancy complications, making vaccination during pregnancy critical for mother-neonate dyads. Few data, often with an unrepresentative sample size, are available on SARS-CoV-2 vaccine-induced humoral and cell-mediated response. Here, we evaluated anti-S antibody and interferon-gamma (IFN-γ) production elicited by SARS-CoV-2 immunization in maternal and neonatal plasma. Pregnant women (n = 230) were prospectively enrolled and classified as unvaccinated (n = 103) and vaccinated (n = 127); after serological screening for previous infections, assays were performed on 126 dyads, 15 mothers and 17 newborns. Positive anti-S antibodies were found in most of the vaccinated subjects, regardless of timespan between immunization and delivery (range: 7-391 days). A total of 89 of 92 vaccinated women showed a broad response to COVID-19 immunization and highly effective placental transfer, as attested by anti-S positive rates (maternal = 96.7%, cord = 96.6%). Most of our subjects had indeterminate results in an IGRA assay, preventing a conclusive evaluation of IFN-γ production. Indeed, pregnancy-related hormonal changes may influence T-cell response with an impact on IFN-γ production. Positive pregnancy and perinatal outcomes reinforce the evidence that the anti-SARS-CoV-2 immunization is effective and well-tolerated in pregnant women and also protective for the fetus/neonate, even though it was not possible to define the related IFN-γ production and role.

RESUMO

BACKGROUND: Breastfeeding has effects on health throughout the lives of mothers and babies. In 2014 in Italy, 10,976 babies were born through ART (assisted reproductive technology), accounting for 2.2% of annual births. The study aims to assess how both social and biological variables and the mode of conception influence breastfeeding. METHODS: This observational study involves 161 pregnancies from three different modes of conception: homologous in vitro fertilization, ovum donation, and spontaneous pregnancies. Neonatal and maternal characteristics were collected from the hospital database, while breastfeeding outcomes were obtained through telephone interviews. RESULTS: The mode of conception did not influence any of the breastfeeding outcomes. Breastfeeding duration was negatively affected by smoking. Vaginal delivery, birth weight > 2500 g, delivery > 37 gestational weeks, breastfeeding intention, and rooming-in are positively associated with the initiation of breastfeeding, while skin-to-skin contact and receiving information concerning breastfeeding are the most significant variables associated with its exclusivity and duration. CONCLUSIONS: The duration and exclusivity of breastfeeding are mainly related with information thereon, promotion, and breastfeeding support, but not with the mode of conception. It is essential to adequately support women from the outset in breastfeeding, as recommended by the World Health Organization (WHO) guidelines.

RESUMO

OBJECTIVES: 1. To assess the performance of an extended questionnaire in identifying cases of SARS-CoV-2 infection among obstetric patients. 2. To evaluate the rate of infection among healthcare workers involved in women's care. STUDY DESIGN: A prospective cohort study of obstetric patients admitted to MBBM Foundation and Buzzi Hospital (Lombardy, Northern Italy) from March 16th to May 22nd, 2020. Women were screened on admission by a questionnaire investigating major and minor symptoms of infection and high-risk contacts in the last 14 days. SARS-CoV-2 assessment was performed by RT-PCR on nasopharyngeal swabs. Till April 7th, a targeted SARS-CoV-2 testing triggered by a positive questionnaire was used; from April 8th, a universal testing approach was implemented. RESULTS: There were 1,177 women screened by the questionnaire, which yielded a positive result in 130 (11.0%) cases. SARS-CoV-2 RT-PCR was performed in 865 (73.5%) patients, identifying 51 (5.9%) infections. During the first period, there were 29 infected mothers, 4 (13.8%) of whom had a negative questionnaire. After universal testing implementation, there were 22 (3%, 95% CI 1.94% - 4.04%) infected mothers, 13 (59.1%) of whom had a negative questionnaire; rate of infection among asymptomatic women was 1.9%. Six of the 17 SARS-CoV-2-positive women with a negative questionnaire reported symptoms more than 14 but within 30 days before admission. Isolated olfactory or taste disorders were identified in 15.7% of infected patients. Rate of infection among healthcare workers was 5.8%. CONCLUSIONS: An exhaustive triage questionnaire can effectively discriminate women at low risk of SARS-CoV-2 infection in the context of a targeted and a universal viral testing approach. In 15.7% of infected women, correct classification as a suspected case of infection was due to investigation of olfactory and taste disorders. Extension of the assessed time-frame to 30 days may be worth considering to increase the questionnaire's performance.

RESUMO

Background: Few studies have evaluated in pregnant women with HIV the prevalence of smoking and its associations with maternal and neonatal outcomes. Objectives: to assess the prevalence of smoking among women with HIV in early pregnancy and the association between smoking and pregnancy outcomes in this particular population. Methods: We used data from a multicenter observational study to define the prevalence of smoking in women with HIV in early pregnancy, and the role of smoking status and intensity as risk factors for adverse maternal and neonatal outcomes. Main outcome measures were fetal growth restriction [FGR], preterm delivery [PD] and low birthweight [LB], evaluated in univariate and multivariate analyses. Results: The overall (2001-2018) prevalence of reported smoking (at least one cigarette/day) was 25.6% (792/3097), with a significant decrease in recent years (19.0% in 2013-2018). Women who smoked were less commonly African, had lower body mass index, older age, a longer history of HIV infection and higher CD4 counts. In univariate analyses, smokers were significantly more likely to have PD, LB, FGR and detectable HIV viral load at third trimester. Multivariable analyses confirmed for smokers a significantly higher risk of LB (adjusted odds ratio [AOR]: 1.69, 95%CI 1.22-2.34) and FGR (AOR 1.88, 95%CI 1.27-2.80), while the associations with detectable HIV and PD were not maintained. Conclusions: The common prevalence of smoking among pregnant women with HIV and its association with adverse outcomes indicates that smoking cessation programs in this population may have a significant impact on neonatal and maternal health.

RESUMO

BACKGROUND: No published studies have evaluated in pregnant women with HIV weight gain with different antiretroviral drug classes. METHODS: Data from a national cohort study were used. We compared absolute weight gain and occurrence of excessive weight gain in women with HIV who received during pregnancy integrase inhibitors (INSTI), protease inhibitors (PI), or non-nucleoside reverse transcriptase inhibitors (NNRTI). Excessive weight gain was defined according to the Institute of Medicine recommendations. Possible predictors of weight gain were assessed using univariate and multivariate analyses. RESULTS: Among 273 cases (PI: 191, NNRTI: 43, INSTI: 39), the mean weight increase was 11.3 kg, and 25.4% of the mothers had an excessive weight increase. No significant differences were found among the three treatment groups for absolute weight increase, occurrence of excessive weight gain, infant birthweight, and other pregnancy and laboratory outcomes. The comparisons of individual drugs, although based on a limited number of cases, suggested no major differences. A significant positive correlation was found between weight gain and CD4+ T-cell increase during pregnancy. In multivariate analyses, drug class and nucleoside backbone were not associated with absolute or excessive weight increase. Excessive weight increase was significantly associated with week of delivery (adjusted odds ratio: 1.74, 95% CI 1.15, 2.63), obesity (5.21, 95% CI 1.85, 14.64), overweight (7.95, 95% CI 3.26, 19.39), recent substance use (5.96, 95% CI 1.13, 31.40) and fasting 2nd trimester hyperglycaemia (3.94, 95% CI 1.14, 13.65). CONCLUSIONS: No significant differences in absolute weight change or occurrence of excessive weight gain were found among women with HIV who received during pregnancy different classes of antiretroviral drugs.

RESUMO

INTRODUCTION: Metabolomics identifies phenotypical groups with specific metabolic profiles, being increasingly applied to several pregnancy conditions. This is the first preliminary study analyzing placental metabolomics in normal weight (NW) and obese (OB) pregnancies. METHODS: Twenty NW (18.5 ≤ BMI< 25 kg/m2) and eighteen OB (BMI≥ 30 kg/m2) pregnancies were studied. Placental biopsies were collected at elective caesarean section. Metabolites extraction method was optimized for hydrophilic and lipophilic phases, then analyzed with GC-MS. Univariate and PLS-DA multivariate analysis were applied. RESULTS: Univariate analysis showed increased uracil levels while multivariate PLS-DA analysis revealed lower levels of LC-PUFA derivatives in the lipophilic phase and several metabolites with significantly different levels in the hydrophilic phase of OB vs NW. DISCUSSION: Placental metabolome analysis of obese pregnancies showed differences in metabolites involved in antioxidant defenses, nucleotide production, as well as lipid synthesis and energy production, supporting a shift towards higher placental metabolism. OB placentas also showed a specific fatty acids profile suggesting a disruption of LC-PUFA biomagnification. This study can lay the foundation to further metabolomic placental characterization in maternal obesity. Metabolic signatures in obese placentas may reflect changes occurring in the intrauterine metabolic environment, which may affect the development of adult diseases.

RESUMO

Magnesium (Mg) and calcium (Ca) are essential cations for women's preconception health. It is well known that, in blood, the concentration of ionized form of these two cations is temporally altered during menstrual cycle, suggesting a correlation between sex steroid hormones and serum calcium and magnesium levels. Evidence from literature suggests that in assisted reproductive technology increasing estrogens during ovarian hyperstimulation may also modulate serum magnesium and calcium levels. Therefore, we first examined total serum magnesium and calcium levels during follicular phase in a large population of infertile patients who underwent intrauterine insemination (IUI). The results were compared to a group of fertile women. Successively, we studied the total serum magnesium and calcium concentrations in infertile patients before and after ovarian hyperstimulation for in vitro fertilization (IVF). Results highlight that total serum concentration of magnesium and calcium does not seem altered in infertile women. During stimulation with gonadotropins, the values of the two cations do not change significantly in ovarian-stimulated women. However, we found a downward trend in the total magnesium and calcium levels in relation to the rising estrogens.

RESUMO

BACKGROUND: Since the first successful use of donated oocytes in 1984, the number of oocyte donation cycles in Europe and the USA has dramatically increased. Consequently, there has been increasing interest in the impact of oocyte donation on maternal and fetal outcomes. OBJECTIVE AND RATIONALE: The aim of this review was to summarize the literature regarding maternal and fetal outcomes from pregnancies conceived through oocyte donation. SEARCH METHODS: Identification of relevant publications was through research within the Embase Medline and PubMed databases, the Google-indexed scientific literature and periodic specialized magazines from the on-line Library Service of the University of Milan. OUTCOMES: Oocyte donation seems to be independently associated with a higher rate of pregnancy-induced hypertension and pre-eclampsia. An explanatory hypothesis is that an immunological maladaptation causes placenta-mediated disorders in oocyte donation pregnancies. The risks are even higher in twin pregnancies. Oocyte donation also seems to be associated with lower fetal birthweight. However, after adjusting for obstetric complications, most studies report less pronounced differences in birthweight or no dissimilarities. The incidence of cesarean section is increased without clear clinical indications. WIDER IMPLICATIONS: Oocyte donation pregnancies are associated with a higher rate of placental disorders of pregnancy, such as gestational hypertension and pre-eclampsia. The risk of poorer neonatal outcomes is increased in oocyte donation pregnancies compared to other in-vitro fertilization pregnancies. Poorer outcomes have been demonstrated especially for twin pregnancies and in association with previous chronic pathologies or the development of obstetrics complications.
