The voltage-dependent anion channel (VDAC), the most abundant protein in the outer mitochondrial membrane, is responsible for the transport of all ions and metabolites into and out of mitochondria. Larger than any of the β-barrel structures determined to date by magic-angle spinning (MAS) NMR, but smaller than the size limit of cryo-electron microscopy (cryo-EM), VDAC1's 31 kDa size has long been a bottleneck in determining its structure in a near-native lipid bilayer environment. Using a single two-dimensional (2D) crystalline sample of human VDAC1 in lipids, we applied proton-detected fast magic-angle spinning NMR spectroscopy to determine the arrangement of β strands. Combining these data with long-range restraints from a spin-labeled sample, chemical shift-based secondary structure prediction, and previous MAS NMR and atomic force microscopy (AFM) data, we determined the channel's structure at a 2.2 Å root-mean-square deviation (RMSD). The structure, a 19-stranded β-barrel, with an N-terminal α-helix in the pore is in agreement with previous data in detergent, which was questioned due to the potential for the detergent to perturb the protein's functional structure. Using a quintuple mutant implementing the channel's closed state, we found that dynamics are a key element in the protein's gating behavior, as channel closure leads to the destabilization of not only the C-terminal barrel residues but also the α2 helix. We showed that cholesterol, previously shown to reduce the frequency of channel closure, stabilizes the barrel relative to the N-terminal helix. Furthermore, we observed channel closure through steric blockage by a drug shown to selectively bind to the channel, the Bcl2-antisense oligonucleotide G3139.Regional anesthesia should be the preferred technique for analgesia in shoulder surgery, which is a frequent procedure in the daily practice of anesthesiologists. The use of ultrasound guidance enables the visualization of the relevant nerve structures and the adjacent anatomical details. Low volumes of local anesthetics reduce the incidence of inadvertent blockade of the phrenic nerve with subsequent respiratory impairment. The additional administration of dexmedetomidine to local anesthetics prolonges the duration of analgesia with a minimal increased incidence of haemodynamic side effects. An optimal workflow is associated with economical advantages due to an improved use of operation rooms. Attention have to be paid regarding intraoperative hypotension, cerebral hypoperfusion and complications due to positioning.The application of novel technologies like artificial intelligence (AI), machine learning (ML) and telemedicine in anesthesiology could play a role in transforming the future of health care. In the present review we discuss the current applications of AI and telemedicine in anesthesiology and perioperative care, exploring their potential influence and the possible hurdles. AI technologies have the potential to deeply impact all phases of perioperative care from accurate risk prediction to operating room organization, leading to increased cost-effective care quality and better outcomes. Telemedicine is reported as a successful mean within the anesthetic pathway, including preoperative evaluation, remote patient monitoring, and postoperative care. The utilization of AI and telemedicine is promising encouraging results in perioperative management, nevertheless several hurdles remain to be overcome before these tools could be integrated in our daily practice. AI models and telemedicine can significantly influence all phases of perioperative care, helping physicians in the development of precision medicine.Anesthesia, perioperative and critical care medicine are specific areas where registries, biobanks and big data are gaining a leading role in increasing knowledge and improving patients' care. The adoption of these robust data infrastructures -aimed at bridling, manipulating, aggregating, and linking patients' multiparametric data- supports anesthesiologists and intensive care physicians in several aspects of bedside practice and clinical research. Indeed, registries-integrated calculators may promote the concept of personalized medicine acting as "sniffers", electronic alarm systems, or decision support systems. Artificial intelligence applied to large databases or meta-registries may further increase dramatically this functionality, identify associations among thousands of different and only apparently uncorrelated variables. From a research perspective, large datasets are increasingly mined to create observations about medical care beyond prospective randomized clinical trials enrolling thousands of patients, often only presumably homogeneous ore well-balanced. https://www.selleckchem.com/products/sb239063.html Registries in this context may effectively explore the association between patients' management and patients' outcomes with a negligible impact on ethical issues, limited costs, and easy management. Finally, registries may promote self-evaluation and continuous quality improvement in the field of perioperative and critical care medicine. In a different way, the role of biobanks primarily relies on translational medical research. These allow rapidly creating pools of biological samples available for epidemiological description, pathophysiological definition, and treatment effectiveness verification, basically acting as an accelerator of knowledge production in critical care and perioperative medicine. Nowadays, registries and biobanks are thus routine tools for anesthesiologists and critical care physicians.Lung ultrasonography provides relevant information on morphological and functional changes occurring in the lungs. However, it correlates weakly with pulmonary congestion and extra vascular lung water. Moreover, there is lack of consensus on scoring systems and acquisition protocols. The automation of this technique may provide promising easy-to-use clinical tools to reduce inter- and intra-observer variability and to standardize scores, allowing faster data collection without increased costs and patients risks.
Although the first attempt success rate of radial artery cannulation has been significantly improved by using dynamic needle tip positioning (DNTP) method, there are still problems with long cannulation time. We hereby observe the effect of ultrasound angle for radial artery cannulation in adult patients.

Adult patients scheduled to undergo elective surgeries with continuous invasive blood pressure monitoring were included and randomly allocated into either a U-P-artery (ultrasound probe perpendicular to the artery) or U-P-needle (ultrasound probe perpendicular to the needle) group. The primary outcome measure was cannulation time at the first attempt, the secondary outcome measures included the first attempt success rate, number of attempts and the total puncture procedure duration. In addition, the incidence of complications was included as secondary outcomes.

Fifty-nine patients were evaluated finally. The cannulation time at the first attempt in U-P-needle group (N.=28) was significantly lower than that in U-P-artery group (N.=31; median [IQR] 16 [13.5-20] seconds vs. 41 [25.5-54.5] seconds, P<0.001). The total puncture procedure duration in group U-P-needle was also shorter than that in the group U-P-artery (median [IQR] 17.4 [13.5-20] seconds vs. 52.2 [25.5-54.5] seconds, P<0.001). No significant difference was observed with respect to first-attempt success rate (96.4% vs. 93.5%, relative risk 0.97, 95% CI 0.863-1.0907, P=0.615). The number of attempts showed no statistical difference as well.

The usage of the U-P-needle approach could remarkably reduce radial arterial cannulation time at the first attempt as well as total puncture procedure duration, comparing with the U-P-artery approach.

Postoperative delirium is a frequent occurrence in the elderly surgical population. As a comprehensive list of predictive factors remains unknown, an opioid-sparing approach incorporating regional anesthesia techniques has been suggested to decrease its incidence. Due to the lack of conclusive evidence on the topic, we conducted a systematic review and meta-analysis to investigate the potential impact of regional anesthesia and analgesia on postoperative delirium.

PubMed, Embase, and the Cochrane central register of Controlled trials (CENTRAL) databases were searched for randomized trials comparing regional anesthesia or analgesia to systemic treatments in patients having any type of surgery. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We pooled the results separately for each of these two applications by random effects modelling. Grading of Recommendations Assessment, Development and Evaluation (GRADE) systemsthesia alone may not decrease postoperative delirium since there are other factors that may influence this outcome.
The contribution of intraoperative anesthetist-administered medications (IAAMs) to the total volume of intraoperative intravenous (IV) fluid therapy and their association with postoperative outcomes has never been formally investigated.

We performed a retrospective study of adult patients undergoing pancreaticoduodenectomy. The volume of IAAMs, crystalloids and colloids, blood and blood products, blood loss, urine output and intraoperative fluid balance were collected. The contribution of IAAMs to the total intraoperative IV fluid volume and postoperative complications was evaluated.

A total of 152 consecutive patients were included. The median volume of IAAMs was 363.8 mL (interquartile range [IQR], (241.0-492.5) delivered at a median rate of 0.61 mL kg hr
(0.40-0.87) over a median duration of surgery of 489 minutes (416.3-605.3). This increased the total administered fluid volume by 5.2% (95% confidence intervals [CI] 4.6, 5.9%) (Cohen's d=1.33, P<0.001). The volume of IAAMs was comparable to thel studies.
We performed this randomized controlled trial to evaluate the effect of opioid-free anesthesia (OFA) on postoperative analgesia after laparoscopic gynecologic surgery.

Seventy-eight patients undergoing laparoscopic gynecologic surgery were randomized to receive either OFA (group OF) or opioid-inclusive anesthesia (group C). Postoperative sufentanil consumption within the first 24 h, Visual Analogue Scale (VAS) for pain, postoperative equivalent milligrams of morphine (EMM), severity of postoperative nausea (PN) and vomiting (PV), prevalence of postoperative nausea and vomiting (PONV), use of antiemetics, time to first passage of flatus were compared by a two-tailed Student's t-test, Wilcoxon rank-sum tests or Fisher's exact tests. Repeated measures ANOVA was used to assess the effect of allocation of groups over time.

The median [IQR] sufentanil consumption within 24 h was lower in group OF (4[4.5]) than in group C (6[8], mean difference [MD]=-2, 95% confidence interval [CI] [-4 to 0], P=0.029). The VASnd faster first passage of flatus.
