Abstract
BACKGROUND Surgical education is highly dependent on intraoperative communication. Trainers must know the trainee's training level to ensure high-quality surgical training. A systematic preoperative dialogue (Educational Team Time Out, ETO) was established to discuss the steps of each surgical procedure. METHODS Over 6 months, ETO was performed within a time limit of 3 minutes. Digital surveys on the utility of ETO and its impact on performance were conducted immediately after surgery and at the end of the study period among the staff of the participating disciplines (trainer, trainee, surgical nursing staff, anaesthesiologists, and medical students). The number of surgical substeps performed was recorded and compared with the equivalent period one year earlier. RESULTS ETO was performed in 64 of the 103 eligible operations (62%). Liver resection (n = 37) was the most frequent procedure, followed by left-sided colorectal surgery (n = 12), partial pancreaticoduodenectomy (n = 6), right-sided hemicolectomies (n = 5), and thyroidectomies (n = 4). Anaesthesiologists most frequently reported that ETO had a direct impact on their work during surgery (90.9%). The influence scores were 46.8% for trainees, 8.8% for trainers, 53.3% for surgical nursing staff and 66.6% for medical students. During the implementation of ETO, a trend towards more assisted substeps in oncologic visceral surgery was seen compared to the corresponding period one year earlier (51% vs.40%; p = 0.11). CONCLUSION ETO leads to improved intraoperative communication and more performed substeps during complex procedures, which increases motivation and practical training. This concept can easily be implemented in all surgical specialties to improve surgical education.

Abstract
PURPOSE The recovery of strength is a key element in successfully returning to sports after ACL reconstruction. The type of anaesthesia has been suspected an influential factor in the post-operative recovery of muscle function. METHODS In this retrospective analysis, n = 442 consecutive patients undergoing primary isolated ACL reconstruction using a hamstring autograft were analysed by pre- and post-operative isokinetic tests in a single orthopaedic centre. These were subdivided into four cohorts: (1) general anaesthesia (n = 47), (2) general anaesthesia with prolonged (48 h) on-demand femoral nerve block (n = 37), (3) spinal anaesthesia (n = 169) and (4) spinal anaesthesia with prolonged (48 h) on-demand femoral nerve block (n = 185). Primary outcome was the change from pre- to post-operative isokinetic strength during knee extension and flexion. RESULTS Using one-way ANOVA, there was no significant influence of the type of anaesthesia. The main effect of anaesthesia on change in extension forces was not significant, and effect sizes were very small (n.s.). Similarly, the main effect of anaesthesia on change in flexion forces was statistically not significant (n.s.). CONCLUSIONS The findings of this study support the interpretation that the type of anaesthesia has no significant effect on the ability to recover thigh muscle strength 6 months after isolated hamstring ACL reconstruction. With regard to the recovery of athletic performance and return-to-sports testing criteria, there is no reason to avoid regional anaesthesia. LEVEL OF EVIDENCE III.

Abstract
PURPOSE In order to translate the FLASH effect in clinical use and to treat deep tumors, Very High Electron Energy irradiations could represent a valid technique. Here, we address the main issues in the design of a VHEE FLASH machine. We present preliminary results for a compact C-band system aiming to reach a high accelerating gradient and high current necessary to deliver a Ultra High Dose Rate with a beam pulse duration of 3μs. METHODS The proposed system is composed by low energy high current injector linac followed by a high acceleration gradient structure able to reach 60-160 MeV energy range. To obtain the maximum energy, an energy pulse compressor options is considered. CST code was used to define the specifications RF parameters of the linac. To optimize the accelerated current and therefore the delivered dose, beam dynamics simulations was performed using TSTEP and ASTRA codes. RESULTS The VHEE parameters Linac suitable to satisfy FLASH criteria were simulated. Preliminary results allow to obtain a maximum energy of 160 MeV, with a peak current of 200 mA, which corresponds to a charge of 600 nC. CONCLUSIONS A promising preliminary design of VHEE linac for FLASH RT has been performed. Supplementary studies are on going to complete the characterization of the machine and to manufacture and test the RF prototypes.

Abstract
The captive breeding of wildlife for commercial purposes is a controversial issue. In South Africa, the farming of African lions (Panthera leo) for commercial trade emerged in the early 1990s, partly as a conservation measure to reduce the decline in wild lion numbers while meeting increasing wildlife trade demands. In May 2021, the South African Department of Forestry, Fisheries, and the Environment (DFFE) announced plans to end the captive breeding of lions, keeping of lions in captivity, and the use of captive lions, their parts and derivatives for commercial trade. Here, we examined the commercial captive lion industry from 2017 to 2020 in the Free State province, the heart of the lion breeding industry. We document the extent of the industry and highlight a number of key management issues. Of particular concern were issues with microchip numbers, which are used to follow each registered lion from birth to death through the system and to avoid laundering of wild caught and/or non-registered lions. Of the 4,823 unique microchips that were identified, at least 11% could not be followed through the system. Additionally, a minimum of 199 microchip numbers may have been reused by permit holders, either on captivity, euthanasia, or transport permits, indicating potential non-compliance with the Threatened or Protected Species (TOPS) Regulations. We highlight further areas of concern that warrant additional attention for these types of activities that may cause management issues during the transition period and which may also be relevant for the keeping, breeding, and trading of other TOPS regulated species in South Africa, particularly big cat species.

Abstract
BACKGROUND Gallbladder cancer (GBC) is an aggressive, uncommon malignancy, with variation in operative approaches adopted across centres and few large-scale studies to guide practice. We aimed to identify the extent of heterogeneity in GBC internationally to better inform the need for future multicentre studies. METHODS A 34-question online survey was disseminated to members of the European-African Hepatopancreatobiliary Association (EAHPBA), American Hepatopancreatobiliary Association (AHPBA) and Asia-Pacific Hepatopancreatobiliary Association (A-PHPBA) regarding practices around diagnostic workup, operative approach, utilization of neoadjuvant and adjuvant therapies and surveillance strategies. RESULTS Two hundred and three surgeons responded from 51 countries. High liver resection volume units (>50 resections/year) organised HPB multidisciplinary team discussion of GBCs more commonly than those with low volumes (p < 0.0001). Management practices exhibited areas of heterogeneity, particularly around operative extent. Contrary to consensus guidelines, anatomical liver resections were favoured over non-anatomical resections for T3 tumours and above, lymphadenectomy extent was lower than recommended, and a minority of respondents still routinely excised the common bile duct or port sites. CONCLUSION Our findings suggest some similarities in the management of GBC internationally, but also specific areas of practice which differed from published guidelines. Transcontinental collaborative studies on GBC are necessary to establish evidence-based practice to minimise variation and optimise outcomes.

Abstract
BackgroundPhysical function is an important factor determining disease burden in arthritis. Monitoring function in rheumatoid arthritis (RA) patients is essential for effective treatment [1]. The currently used tools to assess physical function (e.g. patient reported outcomes) have limitations with respect to sensitivity and specificity to measure functional impairment in RA [2,3]. A marker-based optoelectronic measurement of hand function enables detailed analysis of hand movements such as spatial-temporal parameters and joint angles [4]. This may provide new possibilities to quantitatively and qualitatively analyze the changes of hand function in patients with RA in so far unprecedented way.ObjectivesTo test the feasibility of optoelectronic measurement of hand function in RA patients and healthy controls (HC) when performing standard functional tests such as the Moberg Pick-Up-Test (MPUT) as well as standard movements such as finger flexing and to detect disease specific patterns.MethodsRA patients (ACR/EULAR 2010 criteria [1]) recruited from the Internal Medicine 3 outpatient clinic, Erlangen, Germany and HC were included (Ethics #125_16B). Participants were asked to perform the MPUT and a simple movement of flexing the interphalangeal (DIP) and proximal interphalangeal joint (PIP). Spatial-temporal data of hand movements and hand segment kinematics were captured using an optoelectronic measurement system (Qualisys AB, Sweden) with 29 retroreflective markers (Figure 1). Transport time for each of the 12 MPUT objects was divided into a grasping phase (GP) (first touch to safe grip) and a manipulation phase (MP) (safe grip to drop) using the video recording or marker trajectories. For the flexing movement, the ratios between the flexion angle of the DIP and PIP joint (DIPPIP) were calculated. We used linear mixed-effects models accounting for within-participant clustering of hands and adjusting for age and sex differences to compare RA with controls.Figure 1.Marker setup and the 12 objects transported during the MPUT.ResultsTwenty-four RA patients and 23 healthy controls were evaluated (Table 1). Mean GP times across all objects showed higher absolute differences between the groups (RA 0.43 [0.35-0.52]; HC 0.33 [0.27-0.40] sec) while MP times were identical (RA 0.36 [0.30-0.44]; HC 0.36 [0.30-0.44] sec) showing a significant group-phase interaction (p<0.001). Objects safety pin, key, and paper clip showed the highest absolute between-group mean differences for unadjusted time data (0.41, 0.36, 0.34 sec respectively). Measured angle ratios (RA 0.60±0.15; HC 0.68±0.17 (DIPPIP)) and their linear fit (RA 0.96±0.05; HC 0.97±0.03 R2) were similar for RA and controls (p>0.05).Table 1.Subject characteristics; mean (SD)RAHCmale: female [N]7: 1711: 12Age [years]62.3 (9.1)50.2 (16.1)Disease duration [years]11.8 (10.8)Disease Activity Score (DAS28)2.5 (1.3)ConclusionOptoelectronic measurement of hand function is feasible and allows to gain a more detailed picture of impairment in hand function in RA patients. For instance, tasks like reaching for an object are significantly impaired. Further, objects causing the greatest difficulty for RA patients in the GP were identified. The previously described linear relationship of angle ratios for the distal finger joints in healthy individuals [5] seems also valid for RA patients in our cohort and no significant group differences for the ratio could be observed. This may reflect that DIP and PIP joints are less affected in RA compared to e.g. psoriasis arthritis [6].

Abstract
The illegal wildlife trade (IWT) threatens conservation and biosecurity efforts. The Internet has greatly facilitated the trade of wildlife, and researchers have increasingly examined the Internet to uncover illegal trade. However, most efforts to locate illegal trade on the Internet are targeted to one or few taxa or products. Large-scale efforts to find illegal wildlife on the Internet (e-commerce, social media, dark web) may be facilitated by a systematic compilation of illegally traded wildlife taxa and their uses. Here, we provide such a dataset. We used seizure records from three global wildlife trade databases to compile the identity of seized taxa along with their intended usage (i.e., use-type). Our dataset includes c. 4.9k distinct taxa representing c. 3.3k species and contains c. 11k taxa-use combinations from 110 unique use-types. Further, we acquired over 45k common names for seized taxa from over 100 languages. Our dataset can be used to conduct large-scale broad searches of the Internet to find illegally traded wildlife. Further, our dataset can be filtered for more targeted searches of specific taxa or derived products.

Abstract
India is one of the few countries to have made extensive use of Appendix III of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), compared to other Parties to the Convention. Here we examine India’s use of Appendix III and illustrate its benefits and limitations, using examples of species listed by India in Appendix III. Since its ratification of CITES in 1976, India has listed 39 taxa in Appendix III, 27 species and six subspecies listings of which are still current. Through the listings, important international trade data was gathered, some of which have supported the decision for application to a different CITES Appendix with stricter trade controls. However, the majority of the species have been listed for more than 30 years and a re-evaluation of their listing status and suitability for Appendix III may be warranted. The same applies to the reservations entered by several Parties. We provide recommendations on how to make some of the current listings more effective and encourage other Parties to evaluate their native, non-CITES listed species and, if warranted, to make use of Appendix III to contribute to the conservation of their native wildlife.

Abstract
The unrivaled growth in e-commerce of animals and plants presents an unprecedented opportunity to monitor wildlife trade to inform conservation, biosecurity, and law enforcement. Using the internet to quantify the scale of the wildlife trade (volume and frequency) is a relatively recent and rapidly developing approach that lacks an accessible framework for locating relevant websites and collecting data. We produced an accessible guide for internet-based wildlife trade surveillance. We detailed a repeatable method involving a systematic internet search, with search engines, to locate relevant websites and content. For data collection, we highlight web-scraping technology as an efficient way to collect data in an automated fashion at regularly timed intervals. Our guide is applicable to the multitude of trade-based contexts because researchers can tailor search keywords for specific taxa or derived products and locations of interest. We provide information for working with the diversity of websites used in wildlife trade. For example, to locate relevant content on social media (e.g., posts or groups), each social media platform should be examined individually via the site's internal search engine. A key advantage of using the internet to study wildlife trade is the relative ease of access to an increasing amount of trade-related data. However, not all wildlife trade occurs online and it may occur on unobservable sections of the internet.

Abstract
Time-resolved photoelectron spectroscopy with attosecond precision provides new insights into the photoelectric effect and gives information about the timing of photoemission from different electronic states within the electronic band structure of solids. Electron transport, scattering phenomena and electron-electron correlation effects can be observed on attosecond time scales by timing photoemission from valence band states against that from core states. However, accessing intraband effects was so far particularly challenging due to the simultaneous requirements on energy, momentum and time resolution. Here we report on an experiment utilizing intracavity generated attosecond pulse trains to meet these demands at high flux and high photon energies to measure intraband delays between sp- and d-band states in the valence band photoemission from tungsten and investigate final-state effects in resonant photoemission. Accessing intraband dynamics is challenging due to simultaneous requirements on energy, momentum and time resolution. Here, the authors measure intraband delays between sp- and d-band electronic states in the valence band photoemission from W(110) using intracavity generated attosecond pulse trains.

Abstract
The Philippine Sailfin Lizard (Agamidae: Hydrosaurus pustulatus) is a nationally protected Philippine endemic species. It is threatened by habitat destruction, pollution and overexploitation for the domestic pet trade, yet less is known about the international component of the trade. Here we investigate the international trade in Hydrosaurus spp. (H. weberi, H. amboinensis, and H. pustulatus) with an emphasis on H. pustulatus. We analysed international seizures combined with international online sales and trade data for the United States of America (USA). The export of H. pustulatus from the Philippines has been prohibited since 1991, except under special circumstances, yet they continue to be traded internationally, and we found evidence for trade in Asia, Europe, and North America. Most of these animals, however, were declared to be captive-bred. While imports to and exports from the US consisted mostly of other species of Hydrosaurus, H. pustulatus was by far the most coveted species online, with prices significantly higher for H. pustulatus than any of the other species. While not many seizures have occurred outside the Philippines, even wild-caught individuals were found to be ‘legally’ imported to the USA – in apparent violation of the Lacey Act. We recommend H. pustulatus to be listed in CITES Appendix III, in order for countries other than the USA to have a legal basis to seize wild-caught animals trafficked from the Philippines and to monitor trade in captive-bred specimens. Further, we suggest the use of automated cross-referencing between imported species and the national protection status of the species’ native range states to ensure that legislation violations are detected at the point of import.

Abstract
PURPOSE The aim of this study was to assess the post biopsy infection rate, feasibility and prostate cancer (PCa) detection rate (CDR) by performing transperineal MRI-TRUS fusion biopsy of the prostate (TPBx) under local anesthesia (LA) without antibiotic prophylaxis (AP). METHODS We prospectively screened 766 men with suspicious lesions on mpMRI, an elevated PSA level or a suspect digital examination undergoing MRI-TRUS-TPBx in LA, from May 2019 to July 2020. Patients with the need for antibiotic prophylaxis or without a PI-RADS target lesion were excluded from final analyses. We reported CDR, perioperative pain (0-10) and postoperative complications. PCa with an ISUP grade ≥ 2 was classified as clinically significant PCa (csPCa). RESULTS We included 621 patients with a median age of 68 years (IQR 62-74), a PSA of 6.43 ng/mL (IQR 4.72-9.91) and a prostate volume of 45 cc (IQR 32-64). In median, 4 targeted (TB) (IQR 3-4) and 6 (IQR 5-7) systematic biopsies (SB) detected in combination overall 416 (67%) PCa and 324 (52%) csPCa. Overall CDR of TB for PI-RADS 3, 4 and 5 was 26%, 65% and 84%, respectively. Patients reported a median perioperative pain level of 2 (IQR 1-3). Four patients (0.6%) developed a post biopsy infection, one experienced urosepsis. CONCLUSION Our results demonstrate that transperineal MRI-TRUS fusion-guided prostate biopsy under LA without AP is feasible, safe and well tolerated.

Abstract
The most frequent primary hepatic malignancies are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (intrahepatic cholangiocellular adenocarcinoma [iCCA]). For HCC in cirrhosis, liver transplantation offers the advantage of a complete hepatectomy radically removing all tumorous tissue along with the surrounding cirrhotic parenchyma, which is otherwise associated with a very high risk of recurrence. For HCC in non-cirrhotic livers and iCCA, liver resection is the treatment of choice. Nowadays, even extended resections can be performed with low mortality in experienced centers. Surgical therapy is more and more embedded into multimodal treatment concepts and decision making should be interdisciplinary as for other gastrointestinal tumors.

Abstract
Delayed gastric emptying (DGE) after Ivor-Lewis esophagectomy occurs postoperatively in up to 50% of the patients. This pyloric dysfunction can lead to severe secondary complications postoperatively such as early aspiration, pneumonia or may even have an impact on anastomotic healing and therefore leakage. Early detection of DGE is essential to prevent further complications. The common treatment postoperatively is endoscopic pyloric balloon dilatation (EPBD) after symptoms already occurred. In our work, we analyzed patients who received a preoperative EPBD during the routine restaging endoscopy and compared those patients to a control group to analyze if preoperative EPBD may prevent postoperative DGE and secondary additional complications. We performed a single-center retrospective analysis of 115 patients who received an Ivor-Lewis esophagectomy by the same surgeon between June 2015 and October 2017. Out of these 115 patients, 91 (79.1%) patients received EPBD preoperatively during the staging/restaging endoscopy (PDG, pyloric dilatation group). In 24 (20.9%) patients, preoperative EPBD was not performed due to stenotic esophageal tumors or logistic reasons (NDG, non-pyloric dilatation group). Data of the PDG and NDG group were compared regarding the rate of postoperative DGE as well as DGE and EPBD related complications. In total, 21 (18.3%) patients developed pyloric dysfunction requiring a total of 27 EPBD during follow-up. There were 12 (13.2%) patients in the PDG and 9 (37.5%) patients in the NDG (p = 0.014), respectively. DGE-related complications such as anastomotic leaks (p = 0.466), pulmonary complications (p = 0.466) and longer median hospital stay (p = 0.685) were more frequent in the NDG group; however this difference did not reach statistical significance. The success rate for postoperative EPBD with 20-mm balloons was lower (58.5%) compared to the usage of 30-mm balloons (93.3%). All pre- and postoperative EPBD were performed without any complications. Preoperative EPBD is feasible, safe and can be combined with restating endoscopy. It seems that preoperative EPBD reduces the incidence of DGE and can prevent the need for early postoperative endoscopic interventions. Our recommendation is therefore to perform an EPBD preoperatively when possible to reduce postoperative complications to a minimum. For postoperative EPBD, we recommend the use of the 30-mm balloon due to lower redilatation rates.

Abstract
Laser-dressed photoelectron spectroscopy, employing extreme-ultraviolet attosecond pulses obtained by femtosecond-laser-driven high-order harmonic generation, grants access to atomic-scale electron dynamics. Limited by space charge effects determining the admissible number of photoelectrons ejected during each laser pulse, multidimensional (i.e. spatially or angle-resolved) attosecond photoelectron spectroscopy of solids and nanostructures requires high-photon-energy, broadband high harmonic sources operating at high repetition rates. Here, we present a high-conversion-efficiency, 18.4-MHz-repetition-rate cavity-enhanced high harmonic source emitting 5 × 105 photons per pulse in the 25-to-60-eV range, releasing 1 × 1010 photoelectrons per second from a 10-µm-diameter spot on tungsten, at space charge distortions of only a few tens of meV. Broadband, time-of-flight photoelectron detection with nearly 100% temporal duty cycle evidences a count rate improvement between two and three orders of magnitude over state-of-the-art attosecond photoelectron spectroscopy experiments under identical space charge conditions. The measurement time reduction and the photon energy scalability render this technology viable for next-generation, high-repetition-rate, multidimensional attosecond metrology.

Abstract
Primary hepatobiliary malignancies are hepatocellular carcinoma, cholangiocarcinoma and the rare hepatocellular cholangiocarcinoma (mixed tumor). The indications for liver transplantation and the oncological prognosis differ considerably between these tumor entities. Treatment and decision making for these tumors are often complicated by an underlying chronic liver disease. The aim of this review is to delineate the indications for transplantation and bridging therapies for each cancer entity as well as to highlight some aspects pertinent to transplantation, such as the principles of organ allocation.

Abstract
Streptomyces cinnamonensis A495 is a variant of the monensin producer which instead of the native polyether antibiotic gives rise to antibiotic and anti-tumour shunt-product premonensin. Through the supplementation of the fermentation medium with suitable precursors, premonensin can be derivatized via the incorporation of new-to-nature extender units into the biosynthetic machinery. Polyketide extender units require activation, typically in form of coenzyme A-thioesters. These are membrane impermeable and thus in the past an artificial mimic was employed. Here, we show the use and preliminary characterization of a highly substrate promiscuous new enzyme for the endogenous thioester formation in a Streptomyces strain. These intracellularly activated alternative extender units are significantly better incorporated into premonensin than the synthetically activated counterparts. SIGNIFICANCE AND IMPACT OF THE STUDY Polyketide natural products are of enormous relevance in medicine. The hit-rate in finding active compounds for the potential treatment of various diseases among this substance family of microbial origin is high. However, most polyketides require derivatization to render them suitable for the application. Of relevance in this field is the incorporation of artificial substances into the biogenesis of polyketides, hampered by both the microbial metabolism and the complexity of the enzymes involved. This manuscript describes the straightforward and selective biosynthetic incorporation of synthetic substances into a reduced polyketide and showcases a promising new enzyme to aid this purpose.

Abstract
BACKGROUND Previous studies showed controversial results for the influence of pregnancy-related and perinatal factors on subsequent respiratory and atopic diseases in children. The aim of this study was to assess the association between perinatal variables and the prevalence of asthma, bronchial hyperreactivity (BHR), flexural eczema (FE), allergic rhinitis, and sensitization in childhood and early adulthood. METHODS The studied population was first examined in Munich and Dresden in 1995/1996 at age 9-11 years. Participants were followed until age 19-24 years using questionnaires and clinical examinations. Associations between perinatal data and subsequent atopic diseases were examined using logistic regression analyses adjusting for potential confounders. RESULTS Cesarean section was statistically significantly associated with BHR in early adulthood (odds ratio 4.8 [95% confidence interval 1.5-15.2]), while assisted birth was associated with presence of asthma symptoms in childhood (2.2 [1.2-3.9]), FE symptoms (2.2 [1.2-4.3]) and doctor's diagnosis of atopic dermatitis (1.9 [1.0-3.4]) in childhood, and sensitization in early adulthood (2.2 [1.1-4.3]). Lower birth length (1.9 [1.1-3.2]), lower birthweight (0.5 [0.3-0.9]), and higher birthweight (0.6 [0.4-1.0]) were predictive of sensitization in early adulthood compared to average birth length and birthweight, respectively. None of the other perinatal factors showed statistically significant associations with the outcomes. CONCLUSIONS Our results indicate that children who are born by cesarean section and especially by assisted birth, might be at greater risk for developing asthma, FE, and sensitization and should hence be monitored. Prenatal maternal stress might partly explain these associations, which should be further investigated.

Abstract
Minibeam radiation therapy (MBRT) is an innovative synchrotron radiotherapy technique able to shift the normal tissue complication probability curves to significantly higher doses. However, its exploration was hindered due to the limited and expensive beamtime at synchrotrons. The aim of this work was to develop a cost-effective equipment to perform systematic radiobiological studies in view of MBRT. Tumor control for various tumor entities will be addressable as well as studies to unravel the distinct biological mechanisms involved in normal and tumor tissues responses when applying MBRT. With that aim, a series of modifications of a small animal irradiator were performed to make it suitable for MBRT experiments. In addition, the brains of two groups of rats were irradiated. Half of the animals received a standard irradiation, the other half, MBRT. The animals were followed-up for 6.5 months. Substantial brain damage was observed in the group receiving standard RT, in contrast to the MBRT group, where no significant lesions were observed. This work proves the feasibility of the transfer of MBRT outside synchrotron sources towards a small animal irradiator.
