A first-trimester serum TSH in the 4-10 mIU/L range is associated with obstetric complications in thyroid peroxidase antibody-negative women.

PURPOSE: The impact of mild subclinical hypothyroidism on pregnancy outcomes in TPOAb-negative women is poorly explored. The aim of the present study was the evaluation in a wide cohort of TPOAb-negative pregnant women the role of subclinical hypothyroidism (SCH) on several pregnancy outcomes. METHODS: The study included women aged ≥ 18 years with a singleton pregnancy without known thyroid disease with serum TSH concentration between 0.4 and 10 mIU/L and TPOAb negative. Data about clinical and demographic features were collected. A blood sample was drown to test TSH, TPOAb, ANA and ENA concentration. The mean uterine artery pulsatility index was measured. Risk of adverse obstetric and fetal outcomes was collected. RESULTS: The cohort included 2135 pregnant women. Pregnant women with TSH 4-10 mUI/L had a significantly higher frequency of family history of thyroid diseases, and personal history of celiac disease diseases, type 1 diabetes mellitus, rheumatic disease, antinuclear antibody (ANA) and anti-extractable nuclear antigen (ENA) positive tests. The risk for pre-eclampsia and small for gestational age (SGA) was significantly higher in pregnant women with first-trimester TSH 4-10 mIU/L. A first-trimester TSH serum level greater than 4 mIU/L was associated with a significant increase in the occurrence of abnormal uterine artery pulsatility index, with a more than threefold increase in the risk of developing pre-eclampsia and with the risk of SGA. CONCLUSIONS: In TPOAb-negative pregnant women, a first-trimester serum TSH level ranging from 4 to 10 mIU/L is significantly and independently linked to an increased uterine artery pulsatility index as well as to negative pregnancy outcomes such as pre-eclampsia, SGA and gestational diabetes.

Human cytomegalovirus (HCMV) long-term shedding and HCMV-specific immune response in pregnant women with primary HCMV infection.

Human cytomegalovirus (HCMV) shedding has been extensively investigated in newborns and in young children, however, much less is known about it in immunocompetent adults. Shedding of HCMV was investigated in saliva, vaginal secretions and urine of pregnant women experiencing primary infection along with the development of the HCMV-specific immune response. Thirty-three pregnant women shed HCMV DNA in peripheral biological fluids at least until one year after onset of infection, while in blood HCMV DNA was cleared earlier. Significantly higher levels of viral load were found in vaginal secretions compared to saliva and urine. All subjects examined two years after the onset of infection showed a high avidity index, with IgM persisting in 36% of women. Viral load in blood was directly correlated with levels of HCMV-specific IgM and inversely correlated with levels of IgG specific for the pentameric complex gH/gL/pUL128L; in addition, viral load in blood was inversely correlated with percentage of HCMV-specific CD4+ and CD8+ expressing IL-7R (long-term memory, LTM) while viral load in biological fluids was inversely correlated with percentage of HCMV-specific CD4+ and CD8+ effector memory RA+(TEMRA). In conclusion, viral shedding during primary infection in pregnancy persists in peripheral biological fluids for at least one year and the development of both antibodies (including those directed toward the pentameric complex) and memory T cells are associated with viral clearance.

Vaginal delivery in SARS-CoV-2-infected pregnant women in Northern Italy: a retrospective analysis.

OBJECTIVE: To report mode of delivery and immediate neonatal outcome in women infected with COVID-19. DESIGN: Retrospective study. SETTING: Twelve hospitals in northern Italy. PARTICIPANTS: Pregnant women with COVID-19-confirmed infection who delivered. EXPOSURE: COVID 19 infection in pregnancy. METHODS: SARS-CoV-2-infected women who were admitted and delivered from 1 to 20 March 2020 were eligible. Data were collected from the clinical records using a standardised questionnaire on maternal general characteristics, any medical or obstetric co-morbidity, course of pregnancy, clinical signs and symptoms, treatment of COVID 19 infection, mode of delivery, neonatal data and breastfeeding. MAIN OUTCOME AND MEASURES: Data on mode of delivery and neonatal outcome. RESULTS: In all, 42 women with COVID-19 delivered at the participating centres; 24 (57.1%, 95% CI 41.0-72.3) delivered vaginally. An elective caesarean section was performed in 18/42 (42.9%, 95% CI 27.7-59.0) cases: in eight cases the indication was unrelated to COVID-19 infection. Pneumonia was diagnosed in 19/42 (45.2%, 95% CI 29.8-61.3) cases: of these, 7/19 (36.8%, 95% CI 16.3-61.6) required oxygen support and 4/19 (21.1%, 95% CI 6.1-45.6) were admitted to a critical care unit. Two women with COVID-19 breastfed without a mask because infection was diagnosed in the postpartum period: their newborns tested positive for SARS-Cov-2 infection. In one case, a newborn had a positive test after a vaginal operative delivery. CONCLUSIONS: Although postpartum infection cannot be excluded with 100% certainty, these findings suggest that vaginal delivery is associated with a low risk of intrapartum SARS-Cov-2 transmission to the newborn. TWEETABLE ABSTRACT: This study suggests that vaginal delivery may be associated with a low risk of intrapartum SARS-Cov-2 transmission to the newborn.

Pregnant with HIV before age 25: data from a large national study in Italy, 2001-2016.

Young pregnant women with HIV may be at significant risk of unplanned pregnancy, lower treatment coverage, and other adverse pregnancy outcomes. In a large cohort of pregnant women with HIV in Italy, among 2979 pregnancies followed in 2001-2016, 9·0% were in women <25 years, with a significant increase over time (2001-2005: 7·0%; 2006-2010: 9·1%; 2011-2016: 12·2%, P < 0·001). Younger women had a lower rate of planned pregnancy (23·2% vs. 37·7%, odds ratio (OR) 0·50, 95% confidence interval (CI) 0·36-0·69), were more frequently diagnosed with HIV in pregnancy (46·5% vs. 20·9%, OR 3·29, 95% CI 2·54-4·25), and, if already diagnosed with HIV before pregnancy, were less frequently on antiretroviral treatment at conception (<25 years: 56·3%; ⩾25 years: 69·0%, OR 0·58, 95% CI 0·41-0·81). During pregnancy, treatment coverage was almost universal in both age groups (98·5% vs. 99·3%), with no differences in rate of HIV viral suppression at third trimester and adverse pregnancy outcomes. The data show that young women represent a growing proportion of pregnant women with HIV, and are significantly more likely to have unplanned pregnancy, undiagnosed HIV infection, and lower treatment coverage at conception. During pregnancy, antiretroviral treatment, HIV suppression, and pregnancy outcomes are similar compared with older women. Earlier intervention strategies may provide additional benefits in the quality of care for women with HIV.

Amniocentesis and chorionic villus sampling in HIV-infected pregnant women: a multicentre case series.

OBJECTIVES: To assess in pregnant women with HIV the rates of amniocentesis and chorionic villus sampling (CVS), and the outcomes associated with such procedures. DESIGN: Observational study. Data from the Italian National Program on Surveillance on Antiretroviral Treatment in Pregnancy were used. SETTING: University and hospital clinics. POPULATION: Pregnant women with HIV. METHODS: Temporal trends were analysed by analysis of variance and by the Chi-square test for trend. Quantitative variables were compared by Student's t-test and categorical data by the Chi-square test, with odds ratios and 95% confidence intervals calculated. MAIN OUTCOME MEASURES: Rate of invasive testing, intrauterine death, HIV transmission. RESULTS: Between 2001 and 2015, among 2065 pregnancies in women with HIV, 113 (5.5%) had invasive tests performed. The procedures were conducted under antiretroviral treatment in 99 cases (87.6%), with a significant increase over time in the proportion of tests performed under highly active antiretroviral therapy (HAART) (100% in 2011-2015). Three intrauterine deaths were observed (2.6%), and 14 pregnancies were terminated because of fetal anomalies. Among 96 live newborns, eight had no information available on HIV status. Among the remaining 88 cases with either amniocentesis (n = 75), CVS (n = 12), or both (n = 1), two HIV transmissions occurred (2.3%). No HIV transmission occurred among the women who were on HAART at the time of invasive testing, and none after 2005. CONCLUSIONS: The findings reinforce the assumption that invasive prenatal testing does not increase the risk of HIV vertical transmission among pregnant women under suppressive antiretroviral treatment. TWEETABLE ABSTRACT: No HIV transmission occurred among women who underwent amniocentesis or CVS under effective anti-HIV regimens.

Rate, correlates and outcomes of repeat pregnancy in HIV-infected women.

OBJECTIVES: The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. METHODS: Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. RESULTS: The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/µL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). CONCLUSIONS: Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple children may proceed safely and confidently with subsequent pregnancies.

Cord and blood levels of newborn IgE: Correlation, role and influence of maternal IgE.

The role of cord blood immunoglobulin E (IgE) levels in predicting the development of atopy has been widely investigated. The aim of the study was to evaluate the correlation between serum and cord blood total IgE in newborns and the possible influence of the atopic status of the mother on them. It was also investigated the possible role of gestational age on neonatal total IgE levels. We considered 763 deliveries, 724≥37 weeks of gestation and 39<37 weeks of gestation. 14% of mothers (13.7% at term, 15.4% preterm) showed high total IgE levels. The results showed a significant correlation between serum and cord IgE levels both in preterm and term newborns. The data revealed also that mother's total IgE levels affect both neonatal serum and cord total IgE levels. For the latters we also found child gender as an additional independent predictor. On the contrary total IgE levels are not affected by gestational age. Clinical limitations of total IgE is known but their determination can be useful to define atopy and to suggest follow-up of the children.

Robotic single site staging in endometrial cancer: A multi-institution study.

OBJECTIVE: To evaluate the feasibility and the safety of robotic single site hysterectomy (RSSH) plus or less pelvic lymphadenectomy in FIGO stage I-II endometrial cancer. MATERIALS AND METHODS: We prospectively collected patient demographics, operative times, complications, pathologic results, and length of stay on all patients who underwent RSSH plus or less pelvic lymphadenectomy for clinical FIGO stage I or occult stage II endometrial carcinoma. RESULTS: From January 2012 to February 2015, 125 patients were included in our study. The median age of the patients was 59 years (range, 35-84 years) and the median body mass index was 27 kg/m(2) (range, 19-52 kg/m(2)). One patient was converted to vaginal surgery due to problems of hypercapnia. The median docking time, console time, and total operative time was 11 min (range, 4-40 min), 80 min (range, 20-240 min) and 122 min (range, 35-282 min), respectively. The median blood loss was 50 ml (range, 10-250 ml). No laparoscopic/laparotomic conversion was registered. Twenty one patients underwent pelvic lymphadenectomy (16.8%) and the median pelvic lymph nodes was 13 (range, 3-32). The median time to discharge was 2 days (range, 1-3 days). No intra-operative complications occurred, while we observed 10 (8%) early post-operative complications. CONCLUSION: RSSH plus or less pelvic lymphadenectomy is technically feasible, safe and reproducible and could be the treatment of choice for patients affected by FIGO stage I-II endometrial cancer. However, randomized controlled trials are needed to confirm these results.

Neutralizing and ELISA IgG antibodies to human cytomegalovirus glycoprotein complexes may help date the onset of primary infection in pregnancy.

BACKGROUND: Definition of onset for primary human cytomegalovirus (HCMV) infection during pregnancy is critical for several reasons, including diagnosis of pre-conceptional infections and definition of gestational age at the time of infection. OBJECTIVE: To determine the onset of primary HCMV infection, differential kinetics of antibodies neutralizing infection of epithelial and fibroblast cells, as well as ELISA IgG antibodies to HCMV glycoprotein complexes (gC) gH/gL/pUL128L, gH/gL/gO, and gB were exploited and compared with conventional assays. STUDY DESIGN: In a series of 40 pregnant women with primary HCMV infection and ascertained HCMV-related mild clinical symptoms, the kinetics of different types of neutralizing and ELISA IgG antibodies were investigated with the aim of establishing criteria for dating the onset of primary infection in pregnant women without clinical symptoms. RESULTS: IgG antibodies to gB and gH/gL/pUL128L, as well as antibodies neutralizing infection of epithelial cells appeared early after infection onset (within 2-3 weeks) and increased rapidly, whereas antibodies to gH/gL/gO and antibodies neutralizing infection of fibroblasts appeared later (>30 days) and increased slowly. Both the conventional diagnostic assays (IgG, and IgM antibody, and IgG avidity index) and the novel assays for determination of antibody responses directed against HCMV gC allowed the definition of an algorithm indicating the onset of primary HCMV infection in asymptomatic women within a period of 1-2 months. CONCLUSION: New neutralization and ELISA IgG assays to HCMV gC provide additional tools for dating the onset of primary infection in pregnancy.

Placental lesions associated with oligohydramnios in fetal growth restricted (FGR) pregnancies.

INTRODUCTION: Aim of the study was to investigate the association between placental pathology and oligohydramnios in pregnancies complicated by fetal growth restriction (FGR). METHODS: Placentas from 221 consecutive FGR pregnancies and 63 healthy controls were studied. Pathological lesions were described according to consensus nomenclature and standardized criteria; both elementary lesions and constellations of lesions (patterns) were considered. Statistics included analysis of linear trends and multinomial logistic regression. RESULTS: Amniotic fluid index (AFI) was normal in 56 (25.3%) FGR pregnancies, whereas mild, moderate and severe oligohydramnios were diagnosed in 32 (14.5%), 44 (19.9%) and 89 (40.3%) subjects, respectively. In FGR pregnancies, after adjustment for potential confounders, membrane meconium staining (chi-square = 28.6, p < 0.001), chronic villous hypoxia pattern (chi-square = 18.8, p < 0.001) and fetal thrombotic vasculopathy pattern (chi-square = 9.2, p = 0.002) were positively and linearly correlated to AFI decrease. Odds ratios of meconium and chronic villous hypoxia were 9.2 (95% CI = 2.6-32.9) and 4.2 (95% CI = 1.3-13.6) in FGR pregnancies with normal AFI and 25.2 (95% CI = 6.9-91.8) and 9.7 (95% CI = 3-31.5) in those with severe oligohydramnios (p = 0.005 and p = 0.023 compared to normal AFI, respectively). DISCUSSION: In FGR pregnancies, reduction of amniotic fluid volume is directly correlated to histological features of placental under-perfusion, meconium staining of membranes and fetal vascular damage. These findings support the clinical notion that in FGR pregnancies oligohydramnios is a risk factor of fetal hypoxia and possibly of increased adverse neonatal outcomes.

Candida glabrata and pre-term premature rupture of membrane complicating in vitro pregnancy: case report and confirmation of mother to neonate transmission.

CASE REPORT: We report a case of Candida glabrata infection in an in vitro fertilization-assisted pregnancy complicated by pre-term pre-labor rupture of the membranes. We found C. glabrata in gastric fluid, amniotic fluid and maternal vaginal swab. Neonatal and maternal isolates showed indistinguishable molecular patterns analyzed by fingerprint DNA multilocus. DISCUSSION: Strong consideration should be given to perform a screening test C. glabrata. Multiple treatments, even in pregnancy, should be considered in women who have positive cultures results.

Gonadal and uterine function in female survivors treated by chemotherapy, radiotherapy, and/or bone marrow transplantation for childhood malignant and non-malignant diseases.

OBJECTIVE: To evaluate gonadal function and uterine volume in a cohort of female survivors treated by chemotherapy, radiotherapy, and/or stem cell transplantation (SCT) for childhood malignant and non-malignant diseases. DESIGN: An observational study. SETTING: S. Matteo Hospital, Pavia, Italy. POPULATION: A cohort of 135 female survivors. METHODS: A clinical, hormonal, and ultrasonographic evaluation. Thirty-three patients (24%) had non-malignant haematologic diseases (thalassaemia or sickle cell anaemia), 68 (50%) had leukaemia, 23 (17%) had lymphomas, and 11 (8%) had solid tumours. In total, 106 patients had received SCT, preceded by a conditioning regimen. MAIN OUTCOME MEASURES: Anti-Müllerian hormone (AMH) and Inhibin-B, and uterine volume. RESULTS: The median concentrations of AMH and Inhibin-B in the entire cohort were 0.12 ng/ml (interquartile range, IQR, 0.1-0.5 ng/ml) and 3.5 pg/ml (IQR 0.1-13.2 pg/ml), respectively. In a stepwise ordered logistic regression analysis, conventional chemotherapy for the treatment of malignancies, as opposed to total body irradiation (TBI), was the only oncologically significant predictor of increased AMH levels (OR 4.8, 95% CI 1.9-12, P < 0.001). Conditioning treatment before or after menarche did not influence AMH concentrations (P = 0.24). The best predictor of reduced uterine volume was TBI during the preparation for the allograft (OR 3.5, 95% CI 1.4-8.4, P = 0.006). Increasing age at treatment (OR 0.86, 95% CI 0.77-0.95, P = 0.04), chemotherapy, as opposed to other treatments (OR 0.09, 95% CI 0.03-0.28, P < 0.001), and solid tumours as opposed to either leukaemia/lymphomas or non-malignant diseases (OR 0.2, 95% CI 0.07-0.56, P = 0.002) were associated with larger uterine volumes. CONCLUSIONS: Conditioning therapies for SCT, including TBI, had the worst effects on uterine volume and gonadal reserve. Increasing age at treatment and conventional chemotherapy were associated with less detrimental effects on uterine volume.

Effects of uncomplicated vaginal delivery and epidural analgesia on fetal arterial acid-base parameters at birth in gestational diabetes.

AIM: To investigate the effects of uncomplicated vaginal delivery and epidural analgesia on fetal acid-base parameters in women with gestational diabetes (GDM) compared with controls. METHODS: A retrospective case-control study of 142 women with gestational diabetes and 284 controls. To evaluate the effect of diabetes and analgesia on acid-base status correcting for potential confounders we used ordered logistic equations including quartiles of fetal arterial acid-base parameters collected at birth as outcomes and categories of diabetes and epidural analgesia as explanatory variables. RESULTS: In the GDM group cord base deficit (-2.63 mmol/l, interquartile range [IQR]=4.2 to -0.65 mmol/l vs. -1.9 mmol/l, IQR=-3.3 to -0.2 mmol/l, p=0.009, odds ratio (OR)=1.51, 95% confidence interval (CI)=1.04-2.18) was lower and concentration of calcium higher (1.49 mmol/l, IQR=1.42-1.56 mmol/l vs. 1.47 mmol/l, IQR=1.41-1.51 mmol/l, p=0.009, OR=1.69, 95% CI=1.12-2.56) compared with controls. Epidural analgesia in the GDM group was associated with reduced cord concentration of glucose (84.0mg/dl [4.7 mmol/l], IQR=70-103.3mg/dl vs. 92.5mg/dl [5.1 mmol/l], IQR=76.5-121.8 mg/dl, p=0.004), lactate (2.65 mmol/l (IQR=1.80-4.20) vs. 3.70 mmol/l (IQR=2.90-5.55 mmol/l), p=0.002) and less pronounced base deficit (-2.05 mmol/l, IQR=-3.90 to -0.17 mmol/l vs. -2.8, IQR=-5.57 to -1.05 mmol/l, p=0.01, OR=0.7, 95% CI=0.49-0.99). CONCLUSIONS: In uncomplicated pregnancies and deliveries, well-controlled gestational diabetes mellitus has potentially significant detrimental effects on fetal acid-base status at birth. Epidural analgesia reduces cord arterial glucose and lactates.

Different subsets of circulating angiogenic cells do not predict bronchopulmonary dysplasia or other diseases of prematurity in preterm infants.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease occurring in very and extremely preterm infants undergoing mechanical ventilation. Given the altered lung vascular growth characterizing BPD, circulating angiogenic cells could be useful biomarkers to predict the risk. The objective of the study was to determine whether the percentages of circulating angiogenic cells (CD34+VEGFR-2+, CD34+CD133+VEGFR-2+, and CD45-CD34+CD133+VEGFR-2+ cells), assessed in the peripheral blood at birth by flow cytometry, could be used as markers for the risk of BPD. In one-hundred and forty-two preterm neonates (gestational age less than 32 weeks and/or birth weight less than 1500 g) admitted to our tertiary care Neonatal Intensive Care Unit between 2006 and 2009, we evaluated the percentages of circulating angiogenic cells at birth, at 7 days, and, in a subset of infants (n=40), at 28 days of life. The main outcome was the correlation between cell counts at birth and the subsequent risk of developing BPD. In our study, all the three cell populations failed to predict the development of BPD or other diseases of prematurity. We suggest that these cells cannot be used as biomarkers in preterm infants, and that research is needed to find other early predictors of BPD.

Variation of B-type natriuretic peptide concentrations and intrauterine growth restriction: mother, fetus and newborn.

To evaluate maternal, fetal, neonatal B-type natriuretic peptide (BNP) concentrations related to Intra Uterine Growth Restriction (IUGR). BNP concentrations in 43 IUGR and 35 healthy, Appropriate for Gestational Age (AGA) infants/paired mothers have been compared, from delivery/birth to first month of life. Maternal and IUGR cord BNP concentrations were coupled to fetal ultrasonography. Neonatal echocardiography was performed too. On delivery BNP was higher in all IUGR mothers, suffering or not from gestational hypertension, than in AGA (median 37.14 vs 11.1 pg/ml p=0.002). Maternal BNP was not associated to cord/neonatal BNP or fetal ultrasonographic parameters. Cord BNP was higher in IUGR than AGA newborns (median 23.9 vs 11.4 pg/ml p=0.0007) independently of gestational age, while varied with amniotic fluid (p=0.0044) and umbilical artery flowmetry (p=0.0121). Earlier drop of BNP on day 3 was reported in IUGR neonates (p=0.0001).Ventricular mass change/body weight varied positively in AGA newborns (p<0.001), while declined in IUGR ones (p=0.003). Carrying IUGR fetus is a stress factor resulting in high maternal BNP concentration. Altered fetal ultrasonographic parameters in IUGR newborns lead to higher BNP cord levels. A rapid BNP drop and probable ventricular mass adjustment of IUGR newborns may indicate earlier post-natal cardiovascular adaptation than AGA infants.

HPV infection and intraepithelial lesions: comparison between HIV positive and negative women.

INTRODUCTION: Human Papillomavirus infections have been shown to be crucial for the development of cervical intraepithelial neoplasia and subsequent cervical cancer. The aim of this study is to describe the prevalence of different genotypes of HPV, in a population of HIV-positive women, compared to the negative ones, and their oncogenic risk. PATIENTS AND METHOD: A case-control study comparing HPV genotype distribution between 93 HIV-seropositive and 186 HIV-seronegative women, matched for age and severity of cervical lesions, who attending colposcopic service of our departments for periodical Pap smear and HPV DNA full genotyping by SPF-10 LiPA assay. RESULTS: No significant difference was found in genotype distribution between HIV positive and HIV negative women. Only the prevalence of HPV56 was higher in HIV positive women (p=0,046). The rates of HPV 6, 11, 16 and 18 were similar in both groups. The likelihood of the detection of three or more HPV genotypes was significantly associated with CIN (OR=2.0; 95% CI=1.1-3.8; p= 0.026) but only marginally to HIV-positive serostatus (OR=1.68; 95% CI=0.89-3.16; p= 0.1). High grade cervical lesions are associated with high risk viruses like HPV 16 and 18 and with multiple cervical HPV infections. CONCLUSIONS: The tendency to treat HIV disease with high active antiretroviral therapy may reduce the impact of immunosuppression and make the course of such HPV infections more similar to that among women who are not HIVinfected. As in immunocompetent women, high oncogenic risk viral type and multiple infections are associated with a histologically proven cervical intraepithelial lesions.

Robotic-assisted laparoscopic donor nephrectomy with transvaginal extraction of the kidney.

Transvaginal recovery of the kidney has recently been reported, in a donor who had previously undergone a hysterectomy, as a less-invasive approach to perform laparoscopic live-donor nephrectomy. Also, robotic-assisted laparoscopic kidney donation was suggested to enhance the surgeon's skills during renal dissection and to facilitate, in a different setting, the closure of the vaginal wall after a colpotomy. We report here the technique used for the first case of robotic-assisted laparoscopic live-donor nephrectomy with transvaginal extraction of the graft in a patient with the uterus in place. The procedure was carried out by a multidisciplinary team, including a gynecologist. Total operative time was 215 min with a robotic time of 95 min. Warm ischemia time was 3 min and 15 s. The kidney was pre-entrapped in a bag and extracted transvaginally. There was no intra- or postoperative complication. No infection was seen in the donor or in the recipient. The donor did not require postoperative analgesia and was discharged from the hospital 24 h after surgery. Our initial experience with the combination of robotic surgery and transvaginal extraction of the donated kidney appears to open a new opportunity to further minimize the trauma to selected donors.

Genistein effects on Ca2+ handling in human umbilical artery: inhibition of sarcoplasmic reticulum Ca2+ release and of voltage-operated Ca2+ channels.

Isoflavones are a group of natural phytoestrogens including the compound genistein. Health beneficial effects have been attributed to the consumption of this compound, but the fact that it has estrogen-like activity has raised doubts regarding its potential risk in infants, newborns, or in the fetus and placenta during pregnancy. This work is aimed at studying genistein effects on Ca2+ handling by smooth muscle cells of the human umbilical artery (HUA). Using fluorometric techniques, we found that in these cells genistein reduces the intracellular Ca2+ peak produced by serotonin. The same result could be demonstrated in absence of extracellular Ca2+, suggesting that the isoflavone reduces Ca2+ release from the sarcoplasmic reticulum. Force measurement experiments strengthen these results, since genistein reduced the peak force attained by intact HUA rings stimulated by serotonin in a Ca2+-free solution. Moreover, genistein induced the relaxation of HUA rings precontracted either with serotonin or a depolarizing high-extracellular K+ solution, hinting at a reduction of extracellular Ca2+ entry to the cell. This was confirmed by whole-cell patch-clamp experiments where it was shown that the isoflavone inhibits ionic currents through voltage-operated Ca2+ channels. In summary, we show that genistein inhibits two mechanisms that could increase intracellular Ca2+ in human umbilical smooth muscle cells, behaving in this way as a potential vasorelaxing substance of fetal vessels. Taking into account that genistein is able to cross the placental barrier, these data show that isoflavones may have important implications in the regulation of feto-maternal blood flow in pregnant women who consume soy-derived products as part of their meals.
