RESUMEN
Endoscopy training models (ETM) using artificial organs are practical, hygienic and comfortable for trainees. However, few models exist for training endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy. This training is necessary as the number of bariatric surgeries performed worldwide increases. ETM with human-like anatomy were developed to represent the postoperative anatomy after Billroth II (BII) reconstruction for a standard duodenoscope and the situs of a long-limbed Roux-en-Y (RY) for device-assisted enteroscopy (DAE). In three independent workshops, the models were evaluated by international ERCP experts. In RY model, a simulation for small bowel behavior in endoscopy was created. Thirty-three experts rated the ETM in ERCP expert courses. The BII model was evaluated as suitable for training (school grades 1.36), with a haptic and visual impression rating of 1.73. The RY model was rated 1.50 for training suitability and 2.06 for overall impression. Animal tissue-free ETMs for ERCP in surgically altered anatomy were successfully created. Evaluation by experienced endoscopists indicated that the models are suitable for hands-on ERCP training, including device-assisted endoscopy. It is expected that patient care will improve with appropriate training in advanced procedures.

Objective: Many patients have undergone visceral surgery. The effects on anatomy and physiology, which can result in further surgical or gastroenterological clinical pictures, are equally significant and require special knowledge. This content should be taught in an interdisciplinary elective course. The draft of the new 2025 approval regulation and the current approval regulation specify that preclinical and clinical content should specifically be combined within the framework of a Z-curriculum and that the new elective course should meet these requirements. Methodology: Practical and theoretical aspects of recognising and treating patients with postoperative modified anatomy are to be taught and the findings are to be demonstrated using anatomical and artificial preparations. The curriculum of the preclinical course covers anatomy and physiology. The target group of the curriculum is all participating students with a special interest in topics such as anatomy, visceral surgery and gastroenterology. However, the goal is to involve student tutors of the anatomical dissection courses, who, in turn, will pass on knowledge of modified anatomy to the supervised preclinical students. Results: According to Thomas and Kern, the curriculum development process entails the following six stages: general needs assessment, targeted needs assessment, the formulation of goals and content, the description of strategies, planned implementation and evaluation. Conclusion: A "modified anatomy" curriculum for an interdisciplinary elective course in surgery, gastroenterology, and anatomy was developed. Through the training of anatomy table tutors, a "dovetailing" with the preclinical stage is to be achieved. In addition, new concepts related to the transfer of knowledge and competencies were introduced and should be evaluated for suitability.

Objective: To determine London emergency medicine (EM) doctors' physical activity (PA) characteristics, awareness of PA guidelines and PA prescription practice from London emergency departments (EDs). Methods: An anonymous online survey of EM doctors working in London over 6 weeks between 27 April 2021 and 12 June 2021. Inclusion criteria included EM doctors of any grade currently working in London EDs. Exclusion criteria were non-EM doctors, other healthcare professionals and those working outside London EDs. The Emergency Medicine Physical Activity Questionnaire created consisted of two parts: part 1, on basic demographic data and the Global Physical Activity Questionnaire and part 2, focused questions around awareness of guidelines and prescribing characteristics. Results: 122 participants attempted the survey, of which 75 (61.5%) met the inclusion criteria. 61.3% (n=46) were aware of and 77.3% (n=58) achieved minimum recommended aerobic PA guidelines. However, only 33.3% (n=25) were aware of and 48% (n=36) achieved muscle strengthening (MS) guidelines. The mean sedentary behaviour time/day was 5 hours. 75.3% (n=55) of EM doctors thought it was important to prescribe PA, yet only 41.8% (n=23) prescribed PA. Conclusions: Most London EM doctors are aware of and achieve minimum aerobic PA guidelines. Encouraging MS awareness and activities, as well as PA prescribing, should be areas of focus. Larger studies should take place to assess EM doctors' characteristics in UK regions and data using accelerometers to determine PA more precisely. Further research should also look at patient perceptions of PA.
RESUMEN
The aim of the present work was to develop a PAT strategy for the supervision of hot melt coating processes. Optical fibers were placed at various positions in the process chamber of a fluid bed device. Experiments were performed to determine the most suitable position for in-line process monitoring, taking into account such requirements as a good signal to noise ratio, the mitigation of dead zones, the ability to monitor the product over the entire process, and reproducibility. The experimental evidence suggested that the position at medium fluid bed height, looking towards the center, i.e., normal to particle movement, proved to be the most reliable position. In this study, the advantages of multipoint monitoring are shown, and an in-line-implementation was created. This enabled the real-time supervision of the process, including the fast detection of inhomogeneities and disturbances in the process chamber, and the compensation of sensor malfunction. In addition, a model for estimating the particle size distribution via NIR was successfully created. This ensures that the quality of the product and the endpoint of the coating process can be determined correctly.

BACKGROUND: Trifluoperazine is a long-established high potency typical antipsychotic drug used in the treatment of schizophrenia and schizophrenia-like illnesses. OBJECTIVES: To determine absolute effects of trifluoperazine for schizophrenia and schizophrenia-like illnesses compared with placebo.To critically appraise and summarise current evidence on the resource use, cost and economic evaluation of trifluoperazine compared with placebo for schizophrenia. SEARCH METHODS: Searches of the Cochrane Schizophrenia Group's register of trials (July 2012), supplemented with handsearching, reference searching, personal communication and contact with industry. Two review authors undertook a search for economic studies using the Cochrane Schizophrenia Group's Health Economic Database (CSzGHED) on the 9th April 2013. SELECTION CRITERIA: All available clinical randomised trials involving people with schizophrenia and schizophrenia-like illnesses that compare trifluoperazine with placebo. DATA COLLECTION AND ANALYSIS: Studies for the effects of interventions were reliably selected by a review team and data were doubly independently extracted to reduce bias. We only used dichotomous data, using intention-to-treat analysis when possible. Data were estimated using risk ratio (RR) with 95% confidence intervals (CI). A 'Summary of findings' table was produced, where possible, for each primary outcome using GRADE. Economic studies were searched and reliably selected by review authors (VF and SS) to provide an economic summary of available data. Where no relevant economic studies were eligible for inclusion, the economic review team valued the already-included effectiveness outcome data to provide a rudimentary economic summary. MAIN RESULTS: This review included 10 studies with a total number of 686 participants featuring in 20 different outcomes of interest. Overall, there was significant clinical improvement in clinical global state at medium term amongst people receiving trifluoperazine (3 RCTs, n = 417, RR 4.61, CI 1.54 to 13.84, low quality evidence) and significantly fewer people receiving trifluoperazine left the studies early due to relapse or worsening at medium term (2 RCTs, n = 381, RR 0.34, CI 0.23 to 0.49, low quality evidence). However, results were equivocal for leaving the study early at medium term for any reason (2 RCTs, n = 391, RR 0.80, CI 0.17 to 3.81, very low quality evidence) and due to severe adverse effects (2 RCTs, n = 391, RR 1.54, CI 0.56 to 4.24, very low quality evidence). Equivocal data were also found for intensified symptoms at medium term (2 RCTs, n = 80, RR 1.05, CI 0.54 to 2.05, very low quality evidence) and rates of agitation or distress again at medium term (1 RCT, n = 52, RR 2.00, CI 0.19 to 20.72, very low quality evidence). Comparison between low and high-dose trifluoperazine with placebo from a single study provided equivocal evidence of effects. For economic outcomes, we valued outcomes in GBP terms and presented them in additional tables; there was an estimated saving of £3488.3 in favour of trifluoperazine. However, numerous assumptions were made and these savings need to be interpreted in light of those assumptions. AUTHORS' CONCLUSIONS: Our results agree with existing evidence that compared to placebo, trifluoperazine is an effective antipsychotic for people with schizophrenia. Furthermore, our review provides supportive evidence that trifluoperazine increases the risk of extrapyramidal adverse effects. Although the effect sizes against placebo are similar to those observed with other agents, they are based on data from many small, pre-CONSORT trials with generally either a low or very low GRADE evidence that has limited implication for clinical practice. Large, independent trials are needed that adhere to the CONSORT statement to compare trifluoperazine with placebo used in the treatment of schizophrenia and schizophrenia-like illnesses.
