Weaning Premature Infants from Nasal Continuous Positive Airway Pressure - Current Practice and Scientific Evidence.
2017
Abstract Objective In the past decade, a number of trials have been conducted to determine the optimal strategy of weaning premature infants from nasal continuous airway pressure (nCPAP). However, a paucity of information exists on how weaning is actually performed in clinical routine. Aim of this study was to investigate the current practice of weaning premature infants from nCPAP in Germany. Methods An online survey was performed in German tertiary care neonatal units. Results All 160 German tertiary care units were contacted. Replies were retrieved from 85/160 (53%) units, of which 83/160 (52%) completed the questionnaire. 66/83 (80%) respondents indicated to wean without the use of form…
Alpha emitting nuclides in nuclear medicine theranostics.
2021
Theranostic applications with radio-isotopes currently are rapidly progressing and expand nuclear medicine application in clinical routine. Alpha emitting isotopes, in particular, have long been hypothesized to achieve relevant advances for the treatment of malignancies. Here, an overview of their properties and the knowledge of radiobiology is reviewed in view of clinical translation. Clinical evidence of radiopharmaceuticals based on alpha emitters is summarized with a focus on recent developments for treatment of metastasized castration resistant prostate cancer.Theranostische Anwendungen mit Radioisotopen machen derzeit rasche Fortschritte und erweitern den Einsatz der Nuklearmedizin in…
Research and Clinical Routine in the next Century,Segregation or Cooperative Networks?
2001
Reading the daily newspaper one gets the impression that German universities and clinical research in particular are in a deep crisis, and that German professors are to be blamed for it. In medicine, additional insufficiencies of the system are obvious, beginning with corruption cases brought up against clinicians and ending with conflicts of interest due to the fact that clinical professors in addition to research and teaching devote much of their time to the special care of private patients. These headlines in the news tend to let us forget that during the last decade grant moneys for research projects stagnated whereas the number of grant applications has increased out of proportion. In …
Assaying multiple 125 I seeds with the well-ionization chamber SourceCheck 4π 33005 and a new insert
2015
PURPOSE To provide a practical solution that can be adopted in clinical routine to fulfill the AAPM-ESTRO recommendations regarding quality assurance of seeds used in prostate permanent brachytherapy. The aim is to design a new insert for the well-ionization chamber SourceCheck(4π) 33005 (PTW, Germany) that allows evaluating the mean air-kerma strength of up to ten (125)I seeds with one single measurement instead of measuring each seed individually. MATERIAL AND METHODS The material required is: a) the SourceCheck(4π) 33005 well-ionization chamber provided with a PTW insert to measure the air-kerma strength S K of one single seed at a time; b) a newly designed insert that accommodates ten s…
A methodical 68Ga-labelling study of DO2A-(butyl- l-tyrosine)2 with cation-exchanger post-processed 68Ga: practical aspects of radiolabelling
2011
Positron emission tomography (PET) with 68Ga is a fast-growing field in molecular imaging, both in research and in clinical routine. The availability of 68Ga via the 68Ge/68Ga radionuclide generator facilitates the development and production of radiopharmaceuticals independent of a cyclotron. The presented work shows a complete 68Ga labelling study exemplified on [68Ga]DO2A-(butyl- l-tyrosine)2, a potential tumour tracer for PET. A methodical sequence is followed to optimize the 68Ga-labelling reaction. Practical aspects are described and the different parameters contributing to the labelling yield are demonstrated. The influence of temperature, time, amount of labelling precursor and pH va…
Predicting survival after transarterial chemoembolization for hepatocellular carcinoma using a neural network: A Pilot Study.
2019
BACKGROUND AND AIMS Deciding when to repeat and when to stop transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) can be difficult even for experienced investigators. Our aim was to develop a survival prediction model for such patients undergoing TACE using novel machine learning algorithms and to compare it to conventional prediction scores, ART, ABCR and SNACOR. METHODS For this retrospective analysis, 282 patients who underwent TACE for HCC at our tertiary referral centre between January 2005 and December 2017 were included in the final analysis. We built an artificial neural network (ANN) including all parameters used by the aforementioned risk scores a…
Evaluation eines neuen Softwareassistenten zur automatischen Volumenbestimmung von intrahepatischen Tumoren
2004
Purpose: Computed tomography has become the preferred method in detecting liver carcinomas. The introduction of spiral CT added volumetric assessment of intrahepatic tumors, which was unattainable in the clinical routine with incremental CT due to complex planimetric revisions and excessive computing time. In an ongoing clinical study, a new software tool was tested for the automatic detection of tumor volume and the time needed for this procedure. Materials and Methods: We analyzed patients suffering from hepatocellular carcinoma (HCC). All patients underwent treatment with repeated transcatheter chemoembolization of the hepatic arteria. The volumes of the HCC lesions detected in CT were m…
P172 Mainzer lupus score (MLS) a new questionnaire for lupus treatment
2020
Background For the diagnosis and treatment of the systemic lupus erythematosus (SLE), numerous scores and indices already exist with different focal points, which are mostly extensive and time consuming. The MLS is a short newly developed questionnaire consisting out of four items to consider whether it is necessary to adjust current therapy: Occurrence of new lupus-specific symptoms, subjective measurement of quality of life (Qol), change of serological abnormalities and the occurrence of organ damage accrual. Methods Patients who had at least 3 visits since 2016 in our clinic were able to participate. Spearman-correlation was used to correlate MLS and several other well established scores…
Evaluation of oral anticoagulation therapy: Rationale and design of the thrombEVAL study programme
2013
Since decades, oral anticoagulation (OAC) with vitamin K antagonists (VKA) is an established therapy for both prevention and treatment of thromboembolism in daily clinical routine. Increasing life expectancy, demographic changes, and novel oral anticoagulants have led to an increasing complexity of medical therapy. However, data on quality and management of VKA therapy with phenprocoumon in current medical care are limited. Our aim is to investigate the quality of OAC with VKA in current health care and to evaluate the potential for improvements.The investigator-initiated thrombEVAL study programme comprises two cohorts of patients treated with vitamin K antagonists for oral anticoagulation…
