Expression of aquaporins early in human pregnancy

2011

Abstract Background Aquaporins (AQPs) constitute a family of channel proteins implicated in transmembrane water transport. Thirteen different AQPs (AQP0–12) have been described but their precise biologic function still remains unclear. AQPs 1, 3, 4, 8, and 9 expression has been described in human chorion, amnion and placenta; however, AQP4 is the only that has been identified in the first trimester of human pregnancy. Objective To assess multiplicity of AQPs expression from 10th to 14th week gestation. Population and methods Chorionic villi samples (CVS) collected in pregnant women for prenatal diagnosis were analysed by real time-PCR to assess cDNA expression of AQPs 1, 2, 3, 4, 5, 6, 7, 8…

Changes in beverage consumption from pre-pregnancy to early pregnancy in the Norwegian Fit for Delivery study.

2015

AbstractObjectiveTo describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI.DesignCross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9–20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy.SettingEight local antenatal clinics in southern Norway from September 2009 to February 2013.SubjectsFive hundred and seventy-five healthy pregnant nulliparous women.ResultsPre-pregnancy, 27 % reported drinkin…

Fetus acardius: two- and three-dimensional ultrasonographic diagnoses.

2001

Objective. To determine whether ultrasonographic detection of acardiac fetuses and diagnostic accuracy of related malformations improve with complementary use of two-dimensional ultrasonography, three-dimensional ultrasonography, and Doppler scanning. Methods. Three pregnant women with multifetal gestations who were found to have discordant fetuses on initial two-dimensional ultrasonographic scanning were subsequently scanned with three-dimensional ultrasonography and color Doppler ultrasonography. Results. Although the possibility of acardiac fetuses was entertained in all cases after two-dimensional ultrasonographic scanning, the diagnosis was confirmed, and the accuracy and extent of fet…

Laparoscopic pelvic lymphadenectomy in 32 pregnant patients with cervical cancer: Rationale, description of the technique, and outcome

2014

ObjectiveIndividualized treatment of pregnant patients with cervical cancer is mandatory; hence, information on nodal status is pivotal to allow a waiting strategy in early-stage disease.We aimed to verify the oncological safety and surgical reproducibility of a standardized laparoscopic pelvic lymphadenectomy in pregnant patients with cervical cancer.MethodsWe standardized laparoscopic pelvic lymphadenectomy during the first and second term of gestation in 32 patients with cervical cancer since 1999. According to gestational week (GW) of less than 16 GWs or more than 16 GWs, 2 different techniques were used.ResultsThe International Federation of Gynecology and Obstetrics stages were IA in …

Relationship between Thyroid Status during the First Trimester of Pregnancy and Neonatal Well-Being

2021

Iodine is an essential micronutrient for the synthesis of thyroid hormones. The proper functioning of the thyroid axis is essential for the normal development of the nervous system, especially in the first trimester of gestation. The aim of the present study was to analyze the perinatal outcomes, anthropometry, and APGAR test scores of newborns and to relate them to maternal thyroid status. A total of 190 newborns participated in the study. No correlation was found between thyroid stimulating hormone (TSH) and maternal ioduria values in the first trimester of gestation with the weight or length of the newborn, or the APGAR score at one minute after birth. However, we found significant diffe…

Abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar

2006

Aim  To discuss a rare, but severe complication arising following routine root canal treatment. Summary  An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the or…

The first glimpse of the endometrial microbiota in early pregnancy

2020

Investigation of the microbial community in the female reproductive tract with the use of sequencing techniques has revealed that endometrial samples obtained through a transvaginal catheter are dominated by Lactobacillus species. Dysbiotic changes in the endometrial microbiota may be associated with implantation failure or early spontaneous abortion in patients who undergo assisted reproductive technology treatment. Whether or not there is an endometrial microbiota in early pregnancy is unknown. Herein we describe, the human endometrial microbiota in a patient who subsequently had an 8th week spontaneous clinical miscarriage with euploid embryos in the next cycle and, for the first time, d…

Managing Adult-onset Still's disease: The effectiveness of high-dosage of corticosteroids as first-line treatment in inducing the clinical remission.…

2019

Abstract To assess the effectiveness of the treatment with high dosage of corticosteroids (CCSs), as first-line therapy, in inducing remission in naïve Adult-onset Still's disease (AOSD) patients compared with low dosage of CCSs, after 6 months. To further evaluate the rate of patients maintaining the remission and the rate of CCSs discontinuation, after additional 12 months of follow-up. A retrospective evaluation of patients prospectively followed was designed to compare the rate of clinical remission in naïve AOSD patients treated with high dosages of CCSs (0.8–1 mg/kg/day of prednisone-equivalent) or low dosage of CCSs (0.2–0.3 mg/kg/day of prednisone-equivalent), after 6 months. An add…

On reliability of systems with moving material subjected to fracture and instability

2015

Abstract The reliability of systems with moving cracked elastic and isotropic material is considered. The material is modeled as a moving plate which continually has a crack on the edge. The plate is subjected to homogeneous tension acting in the traveling direction and the tension varies temporally around a constant value, the set tension. The tension and the length of the crack are modeled by an Ornstein–Uhlenbeck process and an exponential Ornstein–Uhlenbeck process, respectively. Failure is regarded as the state at which the plate becomes unstable or fractures (or both) and a lower bound for the reliability of the system is derived. Considering reliability of the system leads to first p…

AbstractBackgroundThe value of the nosological distinction between non-affective and affective psychosis has frequently been challenged. We aimed to investigate the transdiagnostic dimensional structure and associated characteristics of psychopathology at First Episode Psychosis (FEP). Regardless of diagnostic categories, we expected that positive symptoms occurred more frequently in ethnic minority groups and in more densely populated environments, and that negative symptoms were associated with indices of neurodevelopmental impairment.MethodThis study included 2182 FEP individuals recruited across six countries, as part of the EUropean network of national schizophrenia networks studying G…
