Comparison of biometric measurements using partial coherence interferometry and applanation ultrasound
2003
Abstract Purpose To compare and contrast axial length (AL) measurements assessed by ultrasound biometry and optical biometry. Setting Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany. Methods Optical biometry and ultrasound biometry were performed in 360 eyes to measure AL. Results In eyes with a clear-appearing crystalline lens, there was a statistically significant median difference in AL measurements between the 2 methods in eyes with a normal or long length. In eyes with cataract, there was a statistically significant median difference in AL measurements in eyes with a normal or short length. In these cases, optical biometry produced larger readings than ultras…
Endometrial response to concurrent treatment with vaginal progesterone and transdermal estradiol.
2012
ABSTRACT Objective To describe the effect of the intermittent administration of vaginal progesterone and a low-dose estradiol patch on endometrial stability, as assessed by the rate of amenorrhea and endometrial stimulation. Methods This was an open study in which 64 moderately symptomatic, postmenopausal women were treated in the outpatient clinic of our University Hospital for different intervals up to 1 year. The treatment consisted of a combination of patches delivering 25 µg/day estradiol and intravaginal pills containing 100 mg of micronized progesterone. Patches and pills were administered concomitantly in a twice-a-week protocol. The endometrial response was assessed by endovaginal …
Prevalence and correlates of major depressive disorder, bipolar disorder and schizophrenia among nursing home residents without dementia: Systematic …
2020
BackgroundThe elderly population and numbers of nursing homes residents are growing at a rapid pace globally. Uncertainty exists regarding the actual rates of major depressive disorder (MDD), bipolar disorder and schizophrenia as previous evidence documenting high rates relies on suboptimal methodology.AimsTo carry out a systematic review and meta-analysis on the prevalence and correlates of MDD, bipolar disorder and schizophrenia spectrum disorder among nursing homes residents without dementia.MethodMajor electronic databases were systematically searched from 1980 to July 2017 for original studies reporting on the prevalence and correlates of MDD among nursing homes residents without demen…
The influence of oxygen concentration during embryo culture on obstetric and neonatal outcomes: a secondary analysis of a randomized controlled trial.
2020
Abstract STUDY QUESTION Does oxygen concentration during 3-day embryo culture affect obstetric and neonatal outcomes? SUMMARY ANSWER Oxygen concentration during 3-day embryo culture does not seem to affect the obstetric and neonatal outcomes measured. WHAT IS KNOWN ALREADY Atmospheric oxygen appears to be harmful during extended embryo culture. Embryo culture conditions might therefore be a potential risk factor for subsequent fetal development and the health of future children. No data are available concerning the obstetrics and neonatal outcomes after Day 3 transfer of embryos cultured under reduced and atmospheric oxygen tensions. STUDY DESIGN, SIZE, DURATION A secondary analysis of a pr…
Progression of Gastric Acid Production in Preterm Neonates: Utilization of In-vitro Method
2018
Background: There have been limited studies done regarding ability to produce gastric acid in preterm infants. Most studies have used in vivo method of assessing gastric pH. Objectives: The objectives of the study was to assess the feasibility of using an in vitro method of measuring gastric pH in babies ≤ 28 weeks gestational age (GA) and determine whether changes in gastric pH differ with gestational age, mode of delivery, and use of antenatal steroids. Design/Methods: Prospective study that enrolled extremely low birth weight (ELBW) babies. Gastric aspirate was collected before feeding. In vitro testing of gastric aspirates for pH were done on days of life 1, 3, 5, 7, 14, and 28 by using…
Maternal sleep duration and neonate birth weight: A population-based cohort study.
2021
Objective Sleep duration is an important health indicator. Our aim was to investigate the association between maternal sleep duration and infant birthweight. Methods The study included 2,536 mother-infant pairs of a Spanish birth cohort (2004-2006, INMA project). The exposures were questionnaire-based measures of sleep duration before and during pregnancy. The primary outcome was infant birthweight score (g) standardized to 40 weeks of gestation. Results In women sleeping less than 7 hours per day before pregnancy, each additional hour of sleep increased birthweight score by 44.7 g (p = 0.049) in the minimally-adjusted model, although findings were not statistically significant after consid…
The orthopaedic status of severe haemophiliacs in Spain
2000
Summary. This paper provides an outline of the results obtained in a cross-sectional study conducted primarily with the aim of ascertaining orthopaedic complications in a group of young severe A and B haemophiliacs, the effects which these complications have on the medical resources used with these patients, and the impact of severe haemophilia on their quality of life. Its secondary aim was to link their current orthopaedic status to the type of treatment they had received prior to the study. Eleven Spanish hospitals took part in this study, monitoring 70 severe haemophiliacs (FVIII:C 6 months). In 40 cases (57.1%) the patients underwent one or more periods of prophylaxis. Thirty-three pat…
Clinical presentation and outcome of 20 fetuses with parvovirus B19 infection complicated by severe anemia and/or fetal hydrops
2014
Aim The aim of this study was to assess the prognosis of parvovirus B19 infection with severely anemic and/or hydropic fetuses according to initial ultrasound and biological criteria. Material and methods Retrospective study of 20 cases of congenital parvovirus B19-proven infection (positive PCR) complicated by fetal anemia and/or hydrops was examined. Anemia was suspected on an elevated peak systolic velocity of the middle cerebral artery and was confirmed by fetal blood sampling. Results Survival rate was 70% (14/20) overall and 76% (13/17) for fetuses with one or more transfusions. When fetal effusion regressed after the transfusion, all 11 fetuses survived, and neonatal condition was fa…
Impact of estrogens on atherosclerosis and bone in the apolipoprotein E-deficient mouse model.
2014
Objective The common inflammatory pathophysiology has nourished the hypothesis of a relationship between osteoporosis and cardiovascular disease. Estrogens are key agents in the modulation of both processes. We investigated whether induction of atherosclerosis affects bone and whether estrogens modulate both processes. Methods Female apolipoprotein E-deficient mice (a well-established model of atherogenesis) were ovariectomized or falsely operated and fed either standard diet or high-fat diet (HFD). Six animals were included in each of the four groups. To clarify mechanisms, we treated preosteoblastic MC3T3-E1 cells with mouse serum. Results Physiological levels of estrogens in falsely oper…
Relationship between PTH, sex steroid and bone turnover marker measurements and bone density in recently postmenopausal women
2003
Objective: It is conceivable that, since menopause accelerates the continuous bone loss determined by age, a specific configuration of bone mass determinants during the first postmenopausal years occurs. Methods: To establish their value as indicators of bone mass in women with recent natural menopause, we assessed relationships between bone mineral density (BMD) and age, menopausal age, body mass index (BMI), PTH, sex steroid hormones (estradiol and testosterone), and several markers of bone turnover in urine (N-telopeptide and calcium/creatinine ratio) or serum (osteocalcin (OC), total alkaline phosphatase (ALP), total and ionic calcium (iCa), phosphate (P) and magnesium (Mg)) for a group…
