RESUMO
Commercial automation systems for small- and medium-sized laboratories, including research environments, are often complex to use. For liquid handling systems (LHS), development is required not only for the robot's movements but also for adapting the bioanalytical method to the automated system. This study investigates whether a more human-like automation strategy-using a robotic system (RS)-is more suitable for research laboratories than a professional automation approach utilizing a commercial automated LHS. We conducted a series of measurements for protein determination using a Bradford assay manually, with a fully automated LHS, and with our human-like RS. Although the hand-like RS approach requires more than twice the time of the LHS, it achieved the best standard deviation in this setup (RS = 0.5, manual = 0.71, LHS = 0.86). Due to the low limit of detection (LOD) and limit of quantification (LOQ), most protein samples could be quantified with the RS (samples below LOQ = 9.7%, LOD = 0.23; LOQ = 0.25) compared to manual (samples below LOQ = 28.8%, LOD = 0.24; LOQ = 0.26) and the LHS (samples below LOQ = 36.1%, LOD = 0.27; LOQ = 0.31). In another time-dependent enzymatic assay test, the RS achieved results comparable to the manual method and the LHS, although the required time could be a constraint for short incubation times. Our results demonstrate that a more hand-like automation system closely models the manual process, leading easier to accurate bioanalytical results. We conclude that such a system could be more suitable for typical research environments than a complex LHS.
RESUMO
PURPOSE: The aim of this guideline was to find evidence on whether carrying out Doppler examinations and CTGs in low-risk cohorts of pregnant women improves outcomes. METHODS: First, a systematic search for guidelines was carried out. Identified guidelines were evaluated using the DELPHI instrument of the AWMF. Three guidelines were found to be suitable to evaluate CTG. Two DEGUM best practice guidelines were judged suitable to describe the methods. All studies on this issue were additionally analyzed using 8 PICO questions. A structured consensus of the participating professional societies was achieved using a nominal group process and a structured consensus conference moderated by an independent moderator. RECOMMENDATIONS: No antepartum Doppler sonography examinations should be carried out in low-risk cohorts in the context of antenatal care. No antepartum CTG should be carried out in low-risk cohorts. NOTE: The guideline will be published simultaneously in the official journals of both professional societies (i.âe., Geburtshilfe und Frauenheilkunde for the DGGG and Ultraschall in der Medizin/European Journal of Ultrasound for the DEGUM).

RESUMO
Aim The aim of the interdisciplinary S3-guideline Perimenopause and Postmenopause - Diagnosis and Interventions is to provide help to physicians as they inform women about the physiological changes which occur at this stage of life and the treatment options. The guideline should serve as a basis for decisions taken during routine medical care. This short version lists the statements and recommendations given in the long version of the guideline together with the evidence levels, the level of recommendation, and the strength of consensus. Methods The statements and recommendations are largely based on methodologically high-quality publications. The literature was evaluated by experts and mandate holders using evidence-based medicine (EbM) criteria. The search for evidence was carried out by the Essen Research Institute for Medical Management (EsFoMed). To some extent, this guideline also draws on an evaluation of the evidence used in the NICE guideline on Menopause and the S3-guidelines of the AWMF and has adapted parts of these guidelines. Recommendations Recommendations are given for the following subjects: diagnosis and therapeutic interventions for perimenopausal and postmenopausal women, urogynecology, cardiovascular disease, osteoporosis, dementia, depression, mood swings, hormone therapy and cancer risk, as well as primary ovarian insufficiency.
RESUMO
Aims This is an official interdisciplinary guideline published and coordinated by the German Society for Gynecology and Obstetrics (DGGG), the Austrian Society for Gynecology and Obstetrics (OEGGG) and the Swiss Society for Gynecology and Obstetrics (SGGG). The guideline was developed for use in German-speaking regions and is backed by numerous professional societies and organizations. The aim of this guideline is to provide an evidence- and consensus-based overview of the diagnostic approach and the management of hormonal contraception based on a systematic evaluation of the relevant literature. Methods To compile this S3-guideline, a systematic search for evidence was carried out in PubMed and the Cochrane Library to adapt existing guidelines and identify relevant reviews and meta-analyses. A structured evaluation of the evidence was subsequently carried out on behalf of the Guidelines Commission of the DGGG, and a structured consensus was achieved based on consensus conferences attended by representative members from the different specialist societies and professions. Recommendations Evidence-based recommendations about the advice given to women requesting contraception were compiled. The guideline particularly focuses on prescribing contraceptives which are appropriate to women's individual needs, take account of her personal circumstances, and have few or no side effects.
RESUMO
Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Methods The process of updating the S3 guideline dating from 2012 was based on the adaptation of identified source guidelines which were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and the results of a systematic search of literature databases and the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point to develop recommendations and statements which were modified and graded in a structured consensus procedure. Recommendations Part 1 of this short version of the guideline presents recommendations for the screening, diagnosis and follow-up care of breast cancer. The importance of mammography for screening is confirmed in this updated version of the guideline and forms the basis for all screening. In addition to the conventional methods used to diagnose breast cancer, computed tomography (CT) is recommended for staging in women with a higher risk of recurrence. The follow-up concept includes suggested intervals between physical, ultrasound and mammography examinations, additional high-tech diagnostic procedures, and the determination of tumor markers for the evaluation of metastatic disease.

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Method The process of updating the S3 guideline published in 2012 was based on the adaptation of identified source guidelines. They were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and with the results of a systematic search of literature databases followed by the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point and used them to develop suggestions for recommendations and statements, which were then modified and graded in a structured consensus process procedure. Recommendations Part 2 of this short version of the guideline presents recommendations for the therapy of primary, recurrent and metastatic breast cancer. Loco-regional therapies are de-escalated in the current guideline. In addition to reducing the safety margins for surgical procedures, the guideline also recommends reducing the radicality of axillary surgery. The choice and extent of systemic therapy depends on the respective tumor biology. New substances are becoming available, particularly to treat metastatic breast cancer.
RESUMO
INTRODUCTION: The goal of the 2008 updated guideline: early detection of breast cancer in Germany is to support physicians as well as healthy and affected women in the decision-making process involved in the diagnostic chain for the early detection of breast cancer by providing them with evidence- and consensus-based recommendations. The updated guideline replaces the guideline issued in 2003. MATERIALS AND METHODS: The guideline forms the basis for developing an effective and efficient national early breast cancer detection program that meets the standards set by the Council of Europe and WHO for cancer control programs. The guideline presents the current, evidence- and consensus-based state of scientific knowledge in a multidisciplinary approach for the entire diagnostic chain, consisting of history taking and risk consultation, information on health behavior, clinical breast examination, diagnostic imaging, image-guided percutaneous tissue-acquisition techniques, open surgical excisional biopsy and pathomorphological tissue evaluation. The guideline recommends a set of quality indicators to assure resource availability, performance quality and outcomes enhancing total quality management for early breast cancer diagnosis. CONCLUSION: Currently, early detection of breast cancer offers the most promising possibility to optimize the diagnosis and treatment of breast cancer and, as a result, reduce breast cancer mortality and improve health related quality of life in women.

PURPOSE: The antiepileptic drug vigabatrin (VGB) increases intracellular availability of the inhibitory transmitter gamma-aminobutyric acid (GABA) by inhibition of GABA-transaminase. A blockade of the GABA uptake is the main mechanism of action of tiagabine (TGB). Based on this, the two antiepileptic drugs (AEDs) can be speculated to act synergistically so that their combined antiepileptic efficacy is supraadditive. METHODS: To test this, experiments were performed on hippocampal slices of guinea-pigs. As an epilepsy model, epileptiform field potentials (EFPs) were induced by omission of Mg2+ from the bath solution and recorded in stratum pyramidale of the CA3 region. VGB (7.5 microM) and TGB (0.75 microM) were added to the superfusate. RESULTS: VGB, given alone, failed to decrease the repetition rate of EFPs. Similarly, TGB applied alone only transiently led to a nonsignificant reduction of the EFP frequency. Combining VGB and TGB, their suppressive efficacy increased, yielding a significant reduction of EFP frequency, which, however, again did not persist. Pretreatment of the preparations with VGB for 2 h, followed by additional application of TGB, or TGB alone, drastically and persistently potentiated the effects. CONCLUSIONS: These results demonstrate that VGB and TGB show favorable pharmacodynamic interactions, provided VGB is allowed to block intracellular GABA degradation before GABA uptake block by TGB.
