Additive effect of factors related to assisted conception on the reduction of maternal serum pregnancy-associated plasma protein A concentrations and…
2013
Objective To analyze whether assisted conceptions need adjustments in first-trimester Down syndrome screening and why modifications in screening markers occur. Design Eleven-year cohort retrospective analysis. Setting Maternal-fetal medicine unit. Patient(s) Two thousand eleven naturally conceived normal singleton pregnancies and 2,042 normal singleton pregnancies achieved with assisted conception: 350 by IUI and 1,692 with IVF (n = 328) or intracytoplasmic sperm injection (ICSI; n=1,364), using nondonor (n = 1,086) or donated ova (n = 606), with fresh (n = 1,432) or frozen (n = 260) embryos. Intervention(s) Comparison of ultrasound and biochemical markers of first-trimester Down syndrome s…

Event‐related brain potentials to change in rapidly presented acoustic stimuli in newborns
1997
Event-related brain potentials of 28 newborns to pitch change were studied during quiet sleep under stimulus conditions that typically elicit mismatch negativity in adults. Rarely occurring deviant tones of 1100 Hz (probability 12%) were embedded among repeated standard tones of 1000 Hz in an oddball-sequence with an interstimulus interval of 425 ms. Two control conditions were also employed: In the first, the 1100-Hz stimulus was presented alone without the intervening standard stimuli, and in the second the deviant stimulus had a pitch of 1300 Hz. In all conditions the infrequent stimulus elicited in most newborns a slow positive deflection peaking at a latency of 250-350 ms. The response…
Towards enhancing research on adolescent positive mental health
2019
The positive mental health and well-being perspective represents innovative public health research of first-rank priority in Europe. Good mental health is both a state and a resource for everyday life. Hence, the concept often refers to a subjective feeling (hedonic component) as well as positive functioning (eudaimonic component). Different conceptualisations of mental health-related issues are a background to this paper, which gives a brief overview of three research issues in the Nordic countries. First, the development in the occurrences of adolescent mental health-related indicators such as life satisfaction, health, sleep, and school pressure. Second, review of Nordic methodological s…
Dentin degradonomics – The potential role of salivary MMP-8 in dentin caries
2019
Background Dentin caries involves dissolution of minerals which eventually leads to degradation of organic matrix. This degradation which was thought to be by bacterial proteases is now considered to be orchestrated by endogenous collagenases such as Matrix Metalloproteinases (MMPs). This paper aims to estimate the salivary levels of MMP-8 in dental caries and also to asses the various risk factors that contribute to the formation of dental caries. Material and methods A random sample of 75 adults aged 18-35 were included and categorized based on the number of caries lesions (MCL). Standard clinical examinations were performed, and stimulated saliva was collected and analyzed for concentrat…
Obstructive sleep apnoea syndrome: What the anesthesiologist should know
2016
Obstructive sleep apnoea syndrome (OSAS) is a rather common sleep disorder and constitutes a risk or an aggravating factor for various underlying diseases. OSAS is characterised by repeated upper airway collapse during sleep causing fragmented sleep, hypoxemia and hypercapnia. It may also cause considerable changes in intrathoracic pressure and an increase in sympathetic nervous activity, which represent the basis of associated pathologies such as arterial hypertension, ischaemic heart disease, diabetes mellitus, stroke and sudden death [1]. Moreover, there is a well-established association between OSAS and postoperative complications [2, 3]. Nevertheless, a significant proportion of patien…
Everolimus (EVE) and exemestane (EXE) in patients with advanced breast cancer aged ≥ 65 years: New lessons for clinical practice from the EVA study
2018
BACKGROUND: The present analysis focuses on real-world data of Everolimus- Exemestane in advanced HR+ve, HER2-ve elderly breast cancer patients (aged 65 years) included in the EVA study, with unique findings in those aged 70 years. METHODS: Data are collected from clinical records and analysed according to age cut-off (< 65 years; 65 - 69 years and [greater than or equal to] 70 years). Relationship of analyzed variables with response were tested by mean of a Mantel- Haenszel chi square test. Time to event analysis was described by Kaplan Meier approach and association with baseline characteristics was analysed by stratified log-rank test and proportional hazard model. RESULTS: From July …
A low threshold to ECG-gated repeat CTA reduces the risk of false-positive diagnosis of type A dissection in interhospital referrals: a case series s…

Angela Kornberger,1 Iris Burck,2 Hazem El Beyrouti,1 Nancy Halloum,1 Andres Beiras-Fernandez,1 Christian-Friedrich Vahl1 1Department of Cardiothoracic and Vascular Surgery, University Hospital of Johannes Gutenberg University, Mainz, Germany; 2Department of Diagnostic and Interventional Radiology, University Hospital of Johann Wolfgang Goethe University, Frankfurt am Main, Germany Background: False-positive diagnosis of acute Stanford type A aortic dissection (AAD) on computed tomography angiography (CTA) is still an issue and may lead to substantial consequences. Given that electrocardiography (ECG)-gated CTA provides greater diagnostic safety, it may be assumed that interhospital referral…
Beurteilung der Durchgängigkeit von koronaren Bypassgefäßen mit einer 2D T2-gewichteten Turbo-Spin-Echo-Sequenz (HASTE) in Atemanhaltetechnik
1999
AIM To evaluate the patency of coronary artery bypass grafts with a 2D T2-weighted breath-hold turbo-spin-echo sequence. METHODS 38 patients with 97 grafts (19 internal mammary artery and 78 saphenous vein grafts) and a total of 120 distal anastomoses were studied at 1.5 Tesla in supine position using a phased array body coil. An ECG gated 2D T2-weighted breath-hold turbo-spin-echo sequence (HASTE) was performed. Reference method was selective coronary angiography. The image material was evaluated independently by two radiologists (observer one, a radiological fellow and the second a staff radiologist). RESULTS Observer 1 reached a sensitivity of 96% (72/75) and a specificity of 91% (20/22)…
Robot-assisted or pure laparoscopic nerve-sparing radical prostatectomy: What is the optimal procedure for the surgical margins? A single center expe…
2012
Objectives: To compare positive surgical margin rates after robot-assisted and pure laparoscopic radical prostatectomy when neurovascular bundles are preserved, and to identify parameters affecting surgical margin status. Methods: From March 2004 to January 2009, 279 consecutive prostatectomies with preservation of neurovascular bundles were carried out by the same surgeon: 175 robot-assisted radical prostatectomies and 104 laparoscopic radical prostatectomies. An intraperitoneal Montsouris's technique was used for all cases. Patient's age, body mass index, prostate weight, prostate-specific antigen level, clinical stage, preoperative and postoperative Gleason score, percentage of positiv…
