Abstract

Background: The SARS-CoV-2 pandemic is still ongoing and a major challenge for health care services worldwide. In the first WSES COVID-19 emergency surgery survey, a strong negative impact on emergency surgery (ES) had been described already early in the pandemic situation. However, the knowledge is limited about current effects of the pandemic on patient flow through emergency rooms, daily routine and decision making in ES as well as their changes over time during the last two pandemic years. This second WSES COVID-19 emergency surgery survey investigates the impact of the SARS-CoV-2 pandemic on ES during the course of the pandemic. Methods: A web survey had been distributed to medical specialists in ES during a four-week period from January 2022, investigating the impact of the pandemic on patients and septic diseases both requiring ES, structural problems due to the pandemic and time-to-intervention in ES routine. Results: 367 collaborators from 59 countries responded to the survey. The majority indicated that the pandemic still significantly impacts on treatment and outcome of surgical emergency patients (83.1% and 78.5%, respectively). As reasons, the collaborators reported decreased case load in ES (44.7%), but patients presenting with more prolonged and severe diseases, especially concerning perforated appendicitis (62.1%) and diverticulitis (57.5%). Otherwise, approximately 50% of the participants still observe a delay in time-to-intervention in ES compared with the situation before the pandemic. Relevant causes leading to enlarged time-to-intervention in ES during the pandemic are persistent problems with in-hospital logistics, lacks in medical staff as well as operating room and intensive care capacities during the pandemic. This leads not only to the need for triage or transferring of ES patients to other hospitals, reported by 64.0% and 48.8% of the collaborators, respectively, but also to paradigm shifts in treatment modalities to non-operative approach

Abstract

Background: A high-cholesterol diet (HCD) induces vascular atherosclerosis through vascular inflammatory and immunological processes via TLRs. The aim of this study is to investigate the mRNA expression of TLRs and other noxious biomarkers expressing inflammation, fibrosis, apoptosis, and cardiac dysfunction in the rabbit myocardium during (a) high-cholesterol diet (HCD), (b) normal diet resumption and (c) fluvastatin or rosuvastatin treatment. Methods: Forty-eight male rabbits were randomly divided into eight groups (n = 6/group). In the first experiment, three groups were fed with HCD for 1, 2 and 3 months. In the second experiment, three groups were fed with HCD for 3 months, followed by normal chow for 1 month and administration of fluvastatin or rosuvastatin for 1 month. Control groups were fed with normal chow for 90 and 120 days. The whole myocardium was removed; total RNA was isolated from acquired samples, and polymerase chain reaction, reverse transcription PCR and quantitative real-time PCR were performed. Results: mRNA of TLRs 2, 3, 4 and 8; interleukin-6; TNF-a; metalloproteinase-2; tissue inhibitor of metalloproteinase-1; tumor protein 53; cysteinyl aspartate specific proteinase-3; and brain natriuretic peptide (BNP) increased in HCD. Statins but not resumption of a normal diet decreased levels of these biomarkers and increased levels of antifibrotic factors. Conclusions: HCD increases the levels of TLRs; inflammatory, fibrotic and apoptotic factors; and BNP in the rabbit myocardium. Atherogenic diets adversely affect the myocardium at a molecular level and are reversed by statins. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

16. Packing Optimization for Digital Fabrication

Author

Abstract

We present a design-computation method of design-to-production automation and optimization in digital fabrication; an algorithmic process minimizing material use, reducing fabrication time and improving production costs of complex architectural form. Our system compacts structural elements of variable dimensions within fixed-size sheets of stock material, revisiting a classical challenge known as the two-dimensional bin-packing problem. We demonstrate improvements in performance using our heuristic metric, an approach with potential for a wider range of architectural and engineering design-built digital fabrication applications, and discuss the challenges of constructing free-form design efficiently using operational research methodologies.

Abstract

Background The SARS-CoV-2 pandemic is still ongoing and a major challenge for health care services worldwide. In the first WSES COVID-19 emergency surgery survey, a strong negative impact on emergency surgery (ES) had been described already early in the pandemic situation. However, the knowledge is limited about current effects of the pandemic on patient flow through emergency rooms, daily routine and decision making in ES as well as their changes over time during the last two pandemic years. This second WSES COVID-19 emergency surgery survey investigates the impact of the SARS-CoV-2 pandemic on ES during the course of the pandemic. Methods A web survey had been distributed to medical specialists in ES during a four-week period from January 2022, investigating the impact of the pandemic on patients and septic diseases both requiring ES, structural problems due to the pandemic and time-to-intervention in ES routine. Results 367 collaborators from 59 countries responded to the survey. The majority indicated that the pandemic still significantly impacts on treatment and outcome of surgical emergency patients (83.1% and 78.5%, respectively). As reasons, the collaborators reported decreased case load in ES (44.7%), but patients presenting with more prolonged and severe diseases, especially concerning perforated appendicitis (62.1%) and diverticulitis (57.5%). Otherwise, approximately 50% of the participants still observe a delay in time-to-intervention in ES compared with the situation before the pandemic. Relevant causes leading to enlarged time-to-intervention in ES during the pandemic are persistent problems with in-hospital logistics, lacks in medical staff as well as operating room and intensive care capacities during the pandemic. This leads not only to the need for triage or transferring of ES patients to other hospitals, reported by 64.0% and 48.8% of the collaborators, respectively, but also to paradigm shifts in treatment modalities to non-operative approaches reported by 67.3% of the participants, especially in uncomplicated appendicitis, cholecystitis and multiple-recurrent diverticulitis. Conclusions The SARS-CoV-2 pandemic still significantly impacts on care and outcome of patients in ES. Well-known problems with in-hospital logistics are not sufficiently resolved by now; however, medical staff shortages and reduced capacities have been dramatically aggravated over last two pandemic years.

Abstract

Background A large number of patients who undergo laparoscopic sleeve gastrectomy present with surgical complications. Stenosis, in particular, occurs in .7%–4% of cases. Objectives To report our experience, results, and long-term follow-up after pneumatic dilation of late functional helix stenosis after laparoscopic sleeve gastrectomy. Setting Multicenter study led by an endoscopic tertiary referral center. Methods Thirty-five patients were dilated initially at 30 mm. Thirteen out of 35 patients underwent a second dilation up to 35 mm. Only 8 patients underwent a third pneumatic dilation up to 40 mm. The stricture was localized in the mid-body of the sleeve in 32 patients overall; 3 had narrowing adjacent to the cardia. Eleven twists formed an acute angle between the 2 segments of the stomach, whereas 24 angles were obtuse. Seven out of 35 patients presented with persistent dilated pouch above the twist. Two patients were lost to follow-up. Overall outcome at an average follow-up of 15.5 months after primary surgery (range 7–49 mo) was as follows: 12 clinical failures and 1 technical failure (40%) and 60% (20 out of 33) clinical success. Conclusion Pneumatic dilation of late functional helix stricture is an effective technique for treatment of dysphagia in the majority of patients treated. Complete helix stricture, defined in function of the angle within twist, as well as the presence of a persistently dilated gastric pouch above the kinking, seems to be correlated with higher failure rates.

Abstract

Background: Roux-en-Y gastric bypass (RYGB) is complicated by a leak in 0-4.3% of cases. Treatment by fully covered stents has been reported to be associated with some life-threatening complications. We report our experience of insertion of double pigtail stents. Methods: Thirty-three patients (20M, 43 years-20/65), presenting with a leak at an average of 10 days after RYGB (4-35), were treated by double pigtail stent insertion and a nasojejunal feeding tube. Sixty percent of these patients had undergone surgical drainage prior to stenting for control of sepsis. Thirty leaks were located at the top of staple line and three at the gastro-jejunal anastomosis. At a 4-weekly follow-up, ablation or re-stenting was performed depending on status of fistula closure and patients were placed on normal diet. Results: At the first follow-up, 10/33 fistulae healed, one patient presented with clinical failure (3%) and needed surgery, and 22/33were re-stented. Twenty-one out of these 22 developed a secondary sub-clinical gastro-gastric fistula and one, instead, developed complex (gastro-gastric, gastro-colic) fistula. All (22) primary fistulae healed following four more weeks of treatment. Average treatment duration was of 61 days (28-99). Thirty-two patients (97%) at a follow-up of 1-33 months are asymptomatic. Conclusions: Leaks following RYGB can be successfully and safely managed by double pigtail stents. Upper gastric staple line leaks are responsible for the formation of a secondary sub-clinic gastro-gastric fistula which needs no additional treatment.

Abstract

Endoscopic mucosal resection (EMR) is a well-established technique for excision of colo-rectal polyps, which can be technically challenging when the polyp is inside a diverticulum, as colonic perforation may easily occur due to the lack of muscular coats. Here we report, to our knowledge, the first case of sessile (diminutive) polyp inside a diverticulum being successfully removed entirely by EMR.

Abstract

Over-the-scope clip closure of iatrogenic gastrointestinal tract perforations has been successfully demonstrated, and is usually performed in the immediate peroperative setting [1,2]. We report the first case, to our knowledge, of delayed successful treatment of an iatrogenic colon perforation using an over-the-scope clip. An 80-year-old woman underwent routine colonoscopy. Her medical history was unremarkable apart from unexplained thrombocytopenia (40000 platelets/dL). During endoscopy, a perforation occurred at the level of the sigmoid junction with the left colon (●" Fig.1). At that time, after multidisciplinary discussion, and in view of the successful colonic preparation and the thrombocytopenia, a mini-invasive endoscopic treatment was proposed (the patient being on antibiotics). Two and a half hours later the patient was transferred to our unit for an attempt at clip closure. Using a gastroscope and CO2 insufflation, a 7-mm perforation orifice was visualized. An OTSC 11/6t clip (Ovesco Endoscopy GmbH, Tubingen, Germany) was then delivered, with aspiration of the edges of the orifice (●" Fig.2, ●" Fig.3). Contrast medium study through the endoscope performed at that time did not show any fluid extravasation (●" Fig.4). The day after the procedure, the patient presented localized peritoneal irritation and fever (38°C). Lab tests showed no hyperleukocytosis, but the C-reactive protein level had increased to 204U/L. Spiral CT with bowel opacification performed then confirmed a sealed clip closure with no free fluid or air in the peritoneal cavity (●" Fig.5). The patient was kept fasting until bowel transit was re-established 2 days later. She was symptom-free by the Fig.4 Watertight closure with no extravasation of contrast medium.

Abstract

Background: Fully covered self-expanding metal stent (SEMS) placement has been successfully described for the treatment of malignant and benign conditions. The aim of this study is to evaluate our experience of fully covered SEMS placement for post-operative foregut leaks. Materials and methods: Retrospective analysis was done for indications, outcomes and complications of SEMS placed in homogeneous population of 15 patients with post-operative foregut leaks in our tertiary-care centre from December 2008 to December 2010. Stent placement and removal, clinical and radiological evidence of leak healing, migration and other complications were the main outcomes analyzed. Results: Twenty-three HANAROSTENT(®) SEMS were successfully placed in 14/15 patients (93%) with post-operative foregut leaks for an average duration of 28.73 days (range=1-42 days) per patient and 18.73 days per SEMS. Three (20%) patients needed to be re-stented for persistent leaks ultimately resulting in leak closure. Total 5/15 (33.33%) patients and 7/23 (30.43%) stents showed migration; 5/7 (71.42%) migrated stents could be retrieved endoscopically. There were mucosal ulceration in 2/15 (13.33%) and pain in 1/15 (6.66%) patients. Conclusions: Stenting with SEMS seems to be a feasible option as a primary care modality for patients with post-operative foregut leaks.

Abstract

Today, fitting bespoke hearing aids involves injecting silicone into patients' ears to produce ear canal molds. These are subsequently 3D scanned to create digital ear canal impressions. However, before digital impressions can be used they require a substantial amount of effort in manual 3D editing. In this article, we present computational methods to pre-process ear canal impressions. The aim is to create automation tools to assist the hearing aid design, manufacturing and fitting processes as well as normalizing anatomical data to assist the study of the outer ear canal's morphology. The methods include classifying the handedness of the impression into left and right ear types, orienting the geometries onto the same coordinate system sense, and removing extraneous artifacts introduced by the silicone mold. We investigate the use of convolutional neural networks for performing these semantic tasks and evaluate their accuracy using a dataset of 3000 ear canal impressions. The neural networks proved highly effective at performing these tasks with 95.8% adjusted accuracy in classification, 92.3% within 20° angular error in registration and 93.4% intersection over union in segmentation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

39. A Novel Ear Impression-Taking Method Using Structured Light Imaging and Machine Learning: A Pilot Proof of Concept Study with Patients' Feedback on Prototype.

Author

Abstract

Introduction: Taking an ear impression is a minimally invasive procedure. A review of existing literature suggests that contactless methods of scanning the ear have not been developed. We proposed to establish a correlation between external ear features with the ear canal and with this proof of concept to develop a prototype and an algorithm for capturing and predicting ear canal information., Methods: We developed a novel prototype using structured light imaging to capture external images of the ear. Using a large database of existing ear impression images obtained by traditional methods, correlation analyses were carried out and established. A deep neural network was devised to build a predictive algorithm. Patients undergoing hearing aid evaluation undertook both methods of ear impression-taking. We evaluated their subjective feedback and determined if there was a close enough objective match between the images obtained from the impression techniques., Results: A prototype was developed and deployed for trial, and most participants were comfortable with this novel method of ear impression-taking. Partial matching of the ear canal could be obtained from the images taken, and the predictive algorithm applied for a few sample images was within good standard of error with proof of concept established., Discussion: Further studies are warranted to strengthen the predictive capabilities of the algorithm and determine optimal prototype imaging positions so that sufficient ear canal information can be obtained for three-dimensional printing. Ear impression-taking may then have the potential to be automated, with the possibility of same-day three-dimensional printing of the earmold to provide timely access.

Abstract

The ear canal is usually described as an S-shaped funnel. In attempting to classify ear-canal shapes obtained from point clouds digitized from molds of 300 ears, the problem of designing criteria for distinguishing and organizing the canal shapes arose. In this work, we extracted features inspired by the S-shape characteristic (critical point, maximum, minimum, twist, writhe, translation, rotation) and, through them, introduced 14 types of ear-canal shapes. This classification allowed comparison of ears within a type and of ears between different types. It expanded our range of descriptors of canal shapes and unlocked perspectives for applications., (© 2023. The Author(s).)

Abstract

Background and Aims: Endoscopic retrograde cholangiopancreatography (ERCP), in surgically altered anatomy (SAA), can be challenging and the optimal technique selection remains debatable. Most common foregut interventions resulting to this burden consist of Billroth II gastrectomy, Whipple surgery and Roux-en-Y anastomoses, including gastric by-pass. This systematic review, with meta-analysis, aimed to compare the rates of successful enteroscope-assisted (EA)-, endosonography-directed transgastric- (EDGE), and laparoscopy-assisted (LA)-ERCP., Methods: A systematic research (Medline) was performed for relative studies, through January 2022. The primary outcome was technical success, defined as approaching the ampulla site. Secondary outcomes included the desired duct cannulation, successful therapeutic manipulations, and complication rates. We performed meta-analyses of pooled data, and subgroup analysis considering the EA-ERCP subtypes (spiral-, double and single balloon-enteroscope). Pooled rates are reported as percentages with 95% Confidence Intervals (95%CIs)., Results: Seventy-six studies were included (3569 procedures). Regarding primary outcome, EA-ERCP was the least effective [87.3% (95%CI: 85.3-89.4); I 2 : 91.0%], whereas EDGE and LA-ERCP succeeded in 97.9% (95%CI: 96.4-99.4; I 2 : 0%) and 99.1% (95%CI: 98.6-99.7; I 2 : 0%), respectively. Similarly, duct cannulation and therapeutic success rates were 74.7% (95%CI: 71.3-78.0; I 2 : 86.9%) and 69.1% (95%CI: 65.3-72.9; I 2 : 91.8%) after EA-ERCP, 98% (95%CI: 96.5-99.6; I 2 : 0%) and 97.9% (95%CI: 96.3-99.4) after EDGE, and 98.6% (95%CI: 97.9-99.2; I 2 : 0%) and 98.5% (95%CI: 97.8-99.2; I 2 : 0%) after LA-ERCP, respectively. The noticed high heterogeneity in EA-ERCP results probably reflects the larger number of included studies, the different enteroscopy modalities and the variety of surgical interventions. Comparisons revealed the superiority of LA-ERCP and EDGE over EA-ERCP ( p ≤ 0.001) for all success-related outcomes, though LA-ERCP and EDGE were comparable ( p ≥ 0.43). ERCP with spiral-enteroscope was inferior to balloon-enteroscope, while the type of the balloon-enteroscope did not affect the results. Most adverse events were recorded after LA-ERCP [15.1% (95%CI: 9.40-20.8); I 2 : 87.1%], and EDGE [13.1% (95%CI: 7.50-18.8); I 2 : 48.2%], significantly differing from EA-ERCP [5.7% (95%CI: 4.50-6.80); p ≤ 0.04; I 2 : 64.2%]., Conclusions: LA-ERCP and EDGE were associated with higher technical, cannulation, and therapeutic success compared to EA-ERCP, though accompanied with more adverse events.

Abstract

Background: A high-cholesterol diet (HCD) induces vascular atherosclerosis through vascular inflammatory and immunological processes via TLRs. The aim of this study is to investigate the mRNA expression of TLRs and other noxious biomarkers expressing inflammation, fibrosis, apoptosis, and cardiac dysfunction in the rabbit myocardium during (a) high-cholesterol diet (HCD), (b) normal diet resumption and (c) fluvastatin or rosuvastatin treatment., Methods: Forty-eight male rabbits were randomly divided into eight groups ( n = 6/group). In the first experiment, three groups were fed with HCD for 1, 2 and 3 months. In the second experiment, three groups were fed with HCD for 3 months, followed by normal chow for 1 month and administration of fluvastatin or rosuvastatin for 1 month. Control groups were fed with normal chow for 90 and 120 days. The whole myocardium was removed; total RNA was isolated from acquired samples, and polymerase chain reaction, reverse transcription PCR and quantitative real-time PCR were performed., Results: mRNA of TLRs 2, 3, 4 and 8; interleukin-6; TNF-a; metalloproteinase-2; tissue inhibitor of metalloproteinase-1; tumor protein 53; cysteinyl aspartate specific proteinase-3; and brain natriuretic peptide (BNP) increased in HCD. Statins but not resumption of a normal diet decreased levels of these biomarkers and increased levels of antifibrotic factors., Conclusions: HCD increases the levels of TLRs; inflammatory, fibrotic and apoptotic factors; and BNP in the rabbit myocardium. Atherogenic diets adversely affect the myocardium at a molecular level and are reversed by statins.

Abstract

A herbal mouthwash containing essential oils of holy basil and mountain tea, extracts of St John's wort and European goldenrod (Bucovia™) and cetylpyridinium chloride, was developed and in vitro tested for its efficiency against biofilm formation by Streptococcus mutans , together with its eradicating activity against already preformed (48 h with saccharose) streptococcal biofilm. The minimum inhibitory (MIC) and bactericidal concentrations (MBC) of the final formulation, as well as of its individual components, were initially determined. The results revealed that the mouthwash needed to be applied at two-times its MIC (0.63% v.v -1 ) to completely inhibit biofilm formation by S. mutans , which was otherwise capable of developing a robust biofilm on the tested surface. Once fully developed, the matrix of the biofilm was found to contain a significant amount of exopolysaccharides protecting the cells, being impossible to eradicate even when exposed to pure mouthwash for 15 min, highlighting the great recalcitrance of biofilm-embedded S. mutans .

Abstract

Given plans to revisit the lunar surface by the late 2020s and to take a crewed mission to Mars by the late 2030s, critical technologies must mature. In missions of extended duration, in situ resource utilization is necessary to both maximize scientific returns and minimize costs. While this present a significantly more complex challenge in the resource-starved environment of Mars, it is similar to the increasing need to develop resource-efficient and zero-waste ecosystems on Earth. Here, we make use of recent advances in the field of bioinspired chitinous manufacturing to develop a manufacturing technology to be used within the context of a minimal, artificial ecosystem that supports humans in a Martian environment., Competing Interests: The authors have declared that no competing interests exist.

46. Circular manufacturing of chitinous bio-composites via bioconversion of urban refuse.

Abstract

Bioinspired manufacturing, in the sense of replicating the way nature fabricates, may hold great potential for supporting a socioeconomic transformation towards a sustainable society. Use of unmodified ubiquitous biological components suggests for a fundamentally sustainable manufacturing paradigm where materials are produced, transformed into products and degraded in closed regional systems with limited requirements for transport. However, adoption is currently limited by the fact that despite their ubiquitous nature, these biopolymers are predominantly harvested as industrial and agricultural products. In this study, we overcome this limitation by developing a link between bioinspired manufacturing and urban waste bioconversion. This result is paramount for the development of circular economic models, effectively connecting the organic by-products of civilization to locally decentralized, general-purpose manufacturing.

Abstract

Cellulose is the most abundant and broadly distributed organic compound and industrial by-product on Earth. However, despite decades of extensive research, the bottom-up use of cellulose to fabricate 3D objects is still plagued with problems that restrict its practical applications: derivatives with vast polluting effects, use in combination with plastics, lack of scalability and high production cost. Here we demonstrate the general use of cellulose to manufacture large 3D objects. Our approach diverges from the common association of cellulose with green plants and it is inspired by the wall of the fungus-like oomycetes, which is reproduced introducing small amounts of chitin between cellulose fibers. The resulting fungal-like adhesive material(s) (FLAM) are strong, lightweight and inexpensive, and can be molded or processed using woodworking techniques. We believe this first large-scale additive manufacture with ubiquitous biological polymers will be the catalyst for the transition to environmentally benign and circular manufacturing models.

Abstract

Background: A large number of patients who undergo laparoscopic sleeve gastrectomy present with surgical complications. Stenosis, in particular, occurs in .7%-4% of cases., Objectives: To report our experience, results, and long-term follow-up after pneumatic dilation of late functional helix stenosis after laparoscopic sleeve gastrectomy., Setting: Multicenter study led by an endoscopic tertiary referral center., Methods: Thirty-five patients were dilated initially at 30 mm. Thirteen out of 35 patients underwent a second dilation up to 35 mm. Only 8 patients underwent a third pneumatic dilation up to 40 mm. The stricture was localized in the mid-body of the sleeve in 32 patients overall; 3 had narrowing adjacent to the cardia. Eleven twists formed an acute angle between the 2 segments of the stomach, whereas 24 angles were obtuse. Seven out of 35 patients presented with persistent dilated pouch above the twist. Two patients were lost to follow-up. Overall outcome at an average follow-up of 15.5 months after primary surgery (range 7-49 mo) was as follows: 12 clinical failures and 1 technical failure (40%) and 60% (20 out of 33) clinical success., Conclusion: Pneumatic dilation of late functional helix stricture is an effective technique for treatment of dysphagia in the majority of patients treated. Complete helix stricture, defined in function of the angle within twist, as well as the presence of a persistently dilated gastric pouch above the kinking, seems to be correlated with higher failure rates., (Copyright © 2017 American Society for Bariatric Surgery.
