BACKGROUND  Motorized spiral enteroscopy (MSE) has been shown to be safe and effective for deep enteroscopy in studies performed at expert centers with limited numbers of patients without previous abdominal surgery. This study aimed to investigate the safety, efficacy, and learning curve associated with MSE in a real-life scenario, with the inclusion of patients after abdominal surgery and with altered anatomy. METHODS  Patients with indications for deep enteroscopy were enrolled in a prospective observational multicenter study. The primary objective was the serious adverse event (SAE) rate; secondary objectives were the diagnostic and therapeutic yield, procedural success, time, and insertion depth. Data analysis was subdivided into training and core (post-training) study phases at centers with different levels of MSE experience. RESULTS  298 patients (120 women; median age 68, range 19-92) were enrolled. In the post-training phase, 21.5 % (n = 54) had previous abdominal surgery, 10.0 % (n = 25) had surgically altered anatomy. Overall, SAEs occurred in 2.3 % (7/298; 95 %CI 0.9 %-4.8 %). The SAE rate was 2.0 % (5/251) in the core group and 4.3 % (2/47) in the training group, and was not increased after abdominal surgery (1.9 %). Total enteroscopy was achieved in half of the patients (n = 42) undergoing planned total enteroscopy. In 295/337 procedures (87.5 %), the anatomical region of interest could be reached. CONCLUSIONS  This prospective multicenter study showed that MSE was feasible and safe in a large cohort of patients in a real-life setting, after a short learning curve. MSE was shown to be feasible in postsurgical patients, including those with altered anatomy, without an increase in the SAE rate.
Recurrent sigmoid volvulus is frequent and sometimes occurs in frail patients with contraindications to surgical sigmoidectomy. Percutaneous endoscopic sigmoidopexy (PES) has recently been proposed as an alternative to elective sigmoidectomy. We aimed to describe the efficacy and safety of PES.

All consecutive patients who underwent PES for recurrent sigmoid volvulus at two French centers between January 2017 and March 2021 were included in this retrospective case series. Recurrent sigmoid volvulus was defined as at least two symptomatic episodes treated by endoscopic decompression. Under endoscopic guidance, anchors were placed to attach the sigmoid to the anterior abdominal wall, allowing the placement of pigtail Chait catheters.

15 patients (60 % female; median age 74 years [range 49-96]) were included. Median number of previous sigmoid volvulus episodes was 3 (range 2-6). Procedures were technically successful with no intraprocedural adverse events for 14 patients (93 %). Peritonitis occurred at Day 2 in one patient (serious adverse event rate 7 %). Median follow-up time was 10 months (range 1-30). No sigmoid volvulus recurrence occurred during follow-up.

PES using Chait catheters was feasible and effective for recurrent sigmoid volvulus and should be considered as an alternative to sigmoidectomy in inoperable patients.

Their transdifferentiation can be achieved by triggering epigenetic remodeling through e. g. post-translational modification of histones. Valproic acid, a branched-chain saturated fatty acid with histone deacetylase inhibitor activity, was linked to the expression of key transcription factors of pancreatic lineage in epithelial cells and insulin transcription. However, the potential of valproic acid to cause cellular reprogramming is not fully understood. To shed further light on it we employed next-generation RNA sequencing, real-time PCR, and protein analyses by ELISA and western blot, to assess the impact of valproic acid on transcriptome and function of Panc-1-cells. Our results indicate that valproic acid has a significant impact on the cell cycle, cell adhesion, histone H3 acetylation, and metabolic pathways as well as the initiation of epithelial-mesenchymal transition through acetylation of histone H3 resulting in α-cell-like characteristics. We conclude that human epithelial pancreatic cells can be transdifferentiated into cells with endocrine properties through epigenetic regulation by valproic acid favoring an α-cell-like phenotype.Vaccination against severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) provides effective protection against infection or severe coronavirus disease 2019 (COVID-19). Moreover, it is regarded as the single most important measure to end the pandemic. Individual vaccination effectiveness is often judged via measurement of anti-SARS-CoV-2 antibodies. However, considering the complexity of the humoral and cellular immune response the question arises whether the relation of anti-SARS-CoV-2 antibody titers and COVID-19 vaccine effectiveness is a myth or a fact? The current article aims to answer this question and provide a short review of the immunological mechanisms of SARS-CoV-2 vaccination. Recommendations for clinical practice are given based on the current evidence and known problems of anti-SARS-CoV-2 antibody measurements after vaccination.The current S3 guideline entitled "Strategies to warrant rational in-hospital use of antibiotics" summarizes evidence-based antibiotic stewardship (ABS) measures that aim to improve clinical outcomes and prevent development and spread of microbial resistance in German hospitals. Most important prerequisite for efficiency and safety of ABS programs is sufficient staffing capacity as well as reliably operating surveillance of (i) pathogens, (ii) antimicrobial resistance and (iii) consumption of antimicrobials. ABS teams require authorization by hospital institutions as units exclusively responsible for antimicrobial audits and implementation of anti-infective interventions. Clinicians should be regularly granted access to in-hospital training programs delivered by ABS experts. Finally yet importantly, the current S3 guideline also highlights future goals, e.g., the structured involvement for nurses in ABS-guided infection management or the promotion of ABS programs in the outpatient sector and in veterinary medicine.Life threatening events after surgery often occur on the ward. These events could be prevented by early detection of clinical deterioration of patients' health status during ward care. Therefore, an adequate monitoring could help to identify patients at risk, since there is an imbalance of monitoring intensity and the occurrence of life-threatening events during hospital stay.Additional monitoring on the general ward could lead to more patient safety. The practicability of additional monitoring needs to be considered, and therefore the use of available monitoring systems on the ward is limited. Capillary refill time (CRT) and the passive leg raise test (PLR) seem to be usable intermittent monitoring techniques.Continuous monitoring systems ensure a better detection of unwanted events and hemodynamic trends. However, the increased workload for the nursing staff and tethered monitors are unfavorable. Future trends of developing wireless monitoring systems are of paramount importance in this respect. Controlling artefacts is crucial for the successful balance between false alarms and "missed events". An adequate reaction is needed when detecting adverse events to avoid a "failure to rescue".Less invasive or even completely non-invasive haemodynamic monitoring technologies have evolved during the last decades. However, the invasive devices such as the pulmonary artery catheter and transpulmonary thermodilution technologies are still the clinical gold standard in terms of advanced haemodynamic monitoring, especially in the treatment of critically ill patients. The current data situation regarding the early use of continuous haemodynamic monitoring in this patient population, specifically flow-based variables such as stroke volume to prevent occult hypoperfusion, is overwhelming. However, the effective implementation of these technologies in daily clinical routine is remarkably low. Given the fact that perioperative morbidity and mortality are higher than anticipated, anaesthesiologists and intensivists are in charge to deal with this problem. The recent advances in minimally invasive and non-invasive haemodynamic monitoring technologies may facilitate a more widespread use in the operating theatre and in critical care patients. This review evaluates the significance of invasive, minimally- and non-invasive monitoring devices and their specific haemodynamic variables in this particular field of perioperative medicine.Goal directed hemodynamic monitoring and the balance in goal directed therapy between adequate fluid/volume therapy and the application of vasoactive or inotropic drugs are the basic elements of modern perioperative therapy.Surgical procedures should be accompanied by as few side effects and complications as possible. Nevertheless, the number of postoperative complications remains surprisingly high, despite of the modern surgical procedures. Anticipation of potential complications in the perioperative period and their rapid treatment build a core competence of anesthesiological action. Thus, it is clear that anesthesia plays a central role in this balancing act.This article aims to provide an overview of the application of the currently available perioperative goal directed hemodynamic monitoring. The current possibilities are discussed by using a case example and an outlook on the future of hemodynamic monitoring is given.Micropropagation is very important for rapid clonal propagation and scientific research of woody plants. However, the micropropagated materials usually show hyperhydricity, which seriously hinders application of the micropropagation. Lycium ruthenicum is an important species of eco-economic forests. Herein, treatment of 'starvation and drying combined with 30 μM AgNO3' (SDCAg+) removed serious hyperhydricity of L. ruthenicum buds regenerated from its green-inflorescence-explants, and then gene expression, metabolites of various phytohormones, chloroplasts, chlorophyll (Chl) and total soluble proteins of the hyperhydric and dehyperhydric leaves were compared and analyzed. The results suggested that the SDCAg+ treatment might remove hyperhydricity of L. ruthenicum through reducing water uptake; increasing water loss; up-regulating the expression of chloroplast-ribosomal-protein genes from nuclear genome; down-regulating the expression of cytoplasmic-ribosomal-protein genes; up-regulating the synthesis of the total soluble proteins; restoring the lamellar structure of chloroplast grana and matrix; improving Chl synthesis and reducing Chl metabolism; increasing expression of light-harvesting Chl protein complex genes and content of Chla and b; up-regulating both photosynthesis and starch and sucrose metabolism KEGG pathways; up-regulating abscisic acid, salicylic acid and their signaling; down-regulating cytokinin, jasmonic acid, jasmonoyl-l-isoleucine and their signaling. Also, the above events interact to form a regulatory network of dehyperhydricity by SDCAg+ treatment. Overall, the study indicated key genes/pathways and physiological/subcellular changes involved in dehyperhydricity and then established a dehyperhydric mechanism model of L. ruthenicum. Cathepsin G Inhibitor I This not only proposed clues for preventing or removing hyperhydricity but also laid foundations for molecular breeding of L. ruthenicum and other species.
