Abstract
The human gut microbiome is attracting increasing attention because of its overall effect on health. Several reviews have investigated the impact of physical activity on the gut microbiome; however, these predominantly concentrate on either endurance or a combination of physical activities. This study aims to describe the effect of resistance or strength training on the gut microbiome of a human population. This rapid review follows the guidelines of the Cochrane Rapid Reviews Guidance along with PRISMA. A review of the literature was carried out using articles indexed by PubMed, Scopus, and Web of Science published in the last 12 years. None of the seven studies included find significant change in the gut microbiome in terms of bacterial taxa composition or overall diversity, though the results show that resistance training might decrease the zonulin level and increase mucin production and thereby reduce inflammation in the gut. Interestingly, two studies point to a gut-muscle axis connection and this is discussed in our paper. However, due to the small number of existing studies and certain methodological disagreements, it was hard to find a consensus on the relationship between the gut microbiome and resistance training.

Abstract
The effect of annealing temperature on the microstructure, defects and optical properties of ZnO thin films are investigated using sol-gel based spin coating method for a range of annealing temperatures from 200∘C to 500∘C. The correlation among the microstructure, defects, impurity content and the optical band gap of films of thickness about 10-12 nm is elucidated. The particle size increases and the optical band gap reduces with the annealing temperature. At 200∘C, amorphous films were formed with particle size less than 10 nm with an optical band gap of about 3.41 eV. As the temperature increases the grain size increases and the defect, impurity content as well as the optical band gap reduces. This could be due to the reduction in the lattice strain. For an average grain size of about 35 nm and above, the band gap asymptotically approaches the theoretical value of ZnO (3.37 eV). The photoluminescence (PL) spectra show a systematic red-shift in the excitonic levels corresponding to the variation in the optical band-gap. The defect emission from Zn-vacancies is observed in the PL spectra and are further supported by the positron annihilation measurements.

Abstract
BACKGROUND Anal intraepithelial neoplasia (AIN) appears in three different stages. AIN 1 and AIN 2 (p16 negative) are defined as low risk and unlikely to progress to invasive anal cancer. AIN 2 (p16 positive) and AIN 3 are of high risk and should be treated because progression rates to anal cancer are around 10% and treatment significantly reduces this risk. The correct treatment is still a matter of debate. Human papilloma virus (HPV) plays a role in the development of AIN. Our aim was to assess anal endoscopic dissection (aESD) as an intervention for AIN3. METHODS We retrospectively evaluated patients who underwent aESD for AIN 3 between December 2017 and March 2023. The interventional technique itself (duration, complications, size of specimen) and patient outcomes (recurrence, progression to anal cancer, re-intervention) were analyzed. RESULTS Fifteen patients with a median age of 52 years (23-78) underwent aESD for AIN 3. All tested specimens were positive for HPV. Median duration of intervention was 56.1 min, one delayed postinterventional bleeding occurred, and specimen size was 12.05 cm2. Median follow-up was 11.17 months. Three recurrences (20%) appeared: one was resected via biopsy and two were again treated with aESD. There was no progression to invasive anal cancer in the follow-up period. CONCLUSIONS Anal endoscopic submucosal dissection seems to be a safe and feasible treatment for AIN. Recurrences are seldom and can be treated again with the same method. Nevertheless, indications for resection in comparison to radiofrequency ablation, pharmacological therapy, and watch-and-wait strategy are still unclear.

Abstract
INTRODUCTION Sleep-disordered breathing (SDB) and non-alcoholic fatty liver disease (NAFLD) are both common comorbidities in obese patients. Structured weight loss programs are effective and can reduce the incidence and severity of obesity-related comorbidities. The objective of the present analysis is to test whether weight loss induced alleviation of SDB is a predictor for improvement of NAFLD. METHODS Obese participants underwent a standardized non-surgical 3 months weight reduction program (800 kilocalories per day with low carbohydrate and fat content). Abdominal sonography for NAFLD (grade 0 to 3) and monitoring for SDB (defined as apnea-hypopnea index [AHI] ≥ 15/h) were performed at baseline and after 3 months. Alleviation of SDB was defined as a shift from AHI≥ 15/h to <15/h. RESULTS 48 patients (48% female, age 42 ± 12 years, body-mass index 40.3 ± 8.1 kg/m2, AHI 14 ± 17/h, 85% NAFLD grade ≥1) participated in the weight loss program. In contrast to the no SDB group, in patients with SDB weight loss of 27.1 ±0 .9 kg (8.4 ± 2.8 kg/m2) after three months was paralleled by a reduction in AHI (-22 ± 17/h), prevalence of SDB (from 31% to 13%), and oxidized low-density lipoprotein (-13 ± 11 U/l). In individuals with preexisting SDB NAFLD grade improved more (2 versus 1, p<0.001) and was at a lower degree at 3 months than in those without SDB (0 versus 1, p = 0.015). In multivariable analysis models, SDB at baseline was associated with improvement of NAFLD grade (B 0.908; 95% CI 0.125, 1.691; p = 0.024), independently of age, sex, and BMI (each p>0.05, respectively). Decreasing BMI (B 0.16 [95%-CI 0.08; 0.23], p<0.001) and alleviation of SDB (B 0.90 [95%-CI 0.21; 1.58], p = 0.012) were independently associated with improvement of NAFLD grade. CONCLUSION Preexisting SDB and weight loss induced alleviation of SDB are predictors for improvement in NAFLD grade, independent of the extent of weight loss. SDB may contribute to the pathogenesis of NAFLD via SDB-induced oxidative stress and inflammation, but the causal mechanism remains unclear.

Abstract
Direct-band-gap Germanium-Tin alloys (Ge1-xSnx) with high carrier mobilities are promising materials for nano- and optoelectronics. The concentration of open volume defects in the alloy, such as Sn and Ge vacancies, influences the final device performance. In this article, we present an evaluation of the point defects in molecular-beam-epitaxy grown Ge1-xSnxfilms treated by post-growth nanosecond-range pulsed laser melting (PLM). Doppler broadening - variable energy positron annihilation spectroscopy and variable energy positron annihilation lifetime spectroscopy are used to investigate the defect nanostructure in the Ge1-xSnxfilms exposed to increasing laser energy density. The experimental results, supported with ATomic SUPerposition calculations, evidence that after PLM, the average size of the open volume defects increases, which represents a raise in concentration of vacancy agglomerations, but the overall defect density is reduced as a function of the PLM fluence. At the same time, the positron annihilation spectroscopy analysis provides information about dislocations and Ge vacancies decorated by Sn atoms. Moreover, it is shown that the PLM reduces the strain in the layer, while dislocations are responsible for trapping of Sn and formation of small Sn-rich-clusters.

Abstract
Hepatitis E virus (HEV) genotype 3 infections in Germany are mainly transmitted zoonotically through the consumption of swine meat. Furthermore, there is evidence that pets might come into contact with HEV, but the relevance of companion animals as possible sources of HEV transmission in Germany still needs to be defined. A monitoring study was therefore carried out on dogs, cats, and horses from Germany. In total 365 serum samples from pets (124 dogs, 119 cats, and 122 horses) were tested for HEV by PCR and for anti-HEV antibodies by a commercial ELISA. The HEV seroprevalence determined by the sero-assay varied significantly between dogs (10%), cats (6%), and horses (2%). Liver injury-related enzymes, alanine transaminase (ALT), and aspartate transaminase (AST) showed no differences between HEV-positive or negative animals. None of the pet serum samples tested positive for PCR. This serological study suggests that dogs and cats are significantly exposed to HEV in Germany, while horses are of minor relevance.

Abstract
Abstract
Background
While conventional frozen sections and other ex vivo microscopy always come along with artefacts, in vivo confocal laser endomicroscopy (CLE) offers less invasive, less manipulated imaging of living tissues. Understanding the distribution of the staining agent sodium-fluorescein (NaFl) plays a key role in establishing in vivo CLE as a new opportunity for real-time transmitted, in vivo imaging.
By comparing the distribution of NaFl in in vivo and ex vivo CLE to conventional fluorescence microscopy of NaFl incubated tumor cell cultures we gain a better understanding of the staining mechanism.
Material and Methods
Sodium-fluorescein is the water-soluble sodium salt of fluorescein and is used as a fluorescent tracer in neurosurgery. The staining agent was applied intravenously at the beginning of the surgical procedure. In vivo CLE of the lesion was performed 30 to 50 minutes later and compared to ex vivo CLE imaging and conventional fluorescence microscopy. In addition, different tumor cell lines derived from malignant gliomas and carcinomas, respectively, were incubated with NaFl in vitro and the uptake of the fluorescent dye was monitored over time.
Results
From initial results, the intraoperative images showed specific fluorescein distribution depending on the architecture of the tumor entity. In most cases, glial tumors demonstrated higher accumulation of the staining agent in the extracellular tumor matrix, whereas the cells of carcinoma metastases appeared to take up NaFl intracellularly. These results were corroborated by NaFl uptake in cell culture experiments.
Compared to ex vivo CLE, in vivo imaging offered a faster assessment of the tissue, brighter images and higher staining levels. Due to movement artefacts and the narrow intraoperative imaging time frame, in vivo CLE images were sometimes impaired by lower image quality.
Conclusion
The specific distribution of the fluorescent agent NaFl allowed for a discrimination between the different neoplastic entities. Images from in vivo and ex vivo confocal laser endomicroscopy showed NaFl uptake in concordance with the results of NaFl incubated cell cultures.
Intraoperative, in vivo confocal laser endomicroscopy shows promising first results in the understanding of brain tumor histomorphology in situ. Being faster and less manipulated by artefacts than ex vivo investigations, it opens up wider opportunities for research and intraoperative diagnostics.

Abstract
Background: Substance misuse is a significant global health concern. In the UK, the prevalence of substance misuse has increased over the past decade and the number of alcohol and drug related deaths are increasing. Individuals with substance dependency issues are entitled to access treatment services. However, the COVID-19 pandemic created significant challenges for public services, including drug and alcohol treatment, and resulted in significant service reconfiguration and a shift from in-person to remote delivery. This study aims to evaluate the delivery of drug and alcohol services in a large metropolitan area in Northern England during the COVID-19 pandemic. It aims to understand the impact of service reconfiguration for services, staff and service users, and to use this understanding to inform the future optimised design of services. Design and methods: The study has five workstreams within a mixed methods framework: (1) Systematic review of literature; (2) Qualitative process evaluation with service providers (digital timelines, focus groups and interviews); (3) Qualitative process evaluation with service users (interviews, focus groups, text based conversations and case studies); (4) Quantitative outcomes and health economic analysis; and (5) Data synthesis and dissemination. Expected Impact of the study for Public Health: The breadth of the study, its novel nature, and the importance of substance misuse as a public health issue, mean that this study will provide valuable findings for those who commission, deliver and use drug and alcohol treatment services nationally and internationally. There will also be important learning for the effective remote delivery of services in sectors beyond drug and alcohol treatment.

Abstract
BackgroundUp to 40% of all diagnostic computed tomography (CT) scans include views of the spine or hips. Among older people, osteoporosis or vertebral fractures have been found in 30% of such CT scans. Our ‘PHOENIX’ intervention repurposes CT scans taken for other reasons to identify fractures and measure bone density as an ‘added extra’. Early detection and treatment of osteoporosis in CT-attending patients could improve health outcomes.ObjectivesTo determine the feasibility and efficacy of PHOENIX versus usual care in a multi-centre, randomised, pragmatic study conducted in Eastern England involving our Cambridge Specialist Hospital ‘hub’ and four regional General Hospital ‘spokes’.MethodsWomen ≥65 and men ≥75 years attending for routine diagnostic CT scans were invited to participate via a novel consent form incorporating FRAX Fracture Risk Assessment questions. After calculating their FRAX 10-year risk score, higher risk patients were block randomised (1:1:1) to Group 1) PHOENIX intervention, 2) Active Control, where the GP was sent the patients’ FRAX answers only, or 3) Usual Care where data were only analysed after 13 months had elapsed. The CT scans of high FRAX risk patients in Group 1 were retrieved by the Cambridge team using NHS Connecting for Health (Burnbank, UK). The team performed vertebral fracture assessment and measured bone density using QCT Pro (Mindways, USA). They added patient-specific treatment and investigation management advice from ‘drop down’ menus before results were reviewed by a physician, authorised and sent to general practitioners (GPs). Baseline CT scans from groups 2 and 3 were assessed in the same way after 13 months to ensure no patient with osteoporosis/fractures was neglected long term. Assuming 25% attrition, the study was powered to find a superior osteoporosis treatment rate in Group 1 (estimated 20%) versus 16% (Active Control) and 5% (Usual Care). Co-primary feasibility endpoints were the ability to a) randomise 375 patients within 10 months and b) retain 75% of survivors able to complete a 1-year bone health outcome questionnaire. Secondary outcomes included osteoporosis/vertebral fracture identification rates and osteoporosis treatment rates. Stakeholder acceptability and economic aspects will be reported separately.ResultsFrom 1828 invites, 595 participants consented to participate of whom 213 were excluded due to ‘low’ FRAX score. Mortality at 12 months was 20%. Both feasibility objectives were achieved: 1) 382 people were randomised within 10 months; 2) 84.4% of survivors at 1 year (95%CI: 80.5, 88.3) were successfully followed-up. Groups were well matched at baseline. The average age of 375 patients (334 female, 41 male) was 75.2 years (74.6, 75.9). Osteoporosis of the hip/spine was present in 41% of 362 analysable CT scans. From the 264 spines that were suitable for VFA, 20% (n=53) were found to have vertebral fractures, with 8.3% having multiple vertebral fractures (n=22). Osteoporosis treatment was reported in 8.5% of Usual Care group (2.9, 14.2) and 24.2% (15.4, 33.0) of PHOENIX group participants, while in the Active Control group (FRAX only) it was 18.8% (10.9, 26.6 p=0.021). In the PHOENIX group, a recommendation to treat was sent to 50 patients’ GPs at baseline. Only 18 of the 50 patients (36%) were found to be taking osteoporosis treatment 12 months after this advice was sent.ConclusionOsteoporosis treatment rates were almost tripled by screening patients attending for routine diagnostic CT scans with waiting room FRAX, CT-bone densitometry and vertebral fracture analysis.AcknowledgementsThis project is funded by the National Institute for Health Research (NIHR) under its Research for Patient Benefit (RfPB) Programme (Grant Reference Number PB-PG-0816-20027) and by the Cambridge NIHR Biomedical Research Centre (BRC-1215-20014).

Abstract
The effect ofin situannealing is investigated in Gd0.1Ca0.9MnO3(GCMO) thin films in oxygen and vacuum atmospheres. We show that the reduction of oxygen content in GCMO lattice by vacuum annealing induced more oxygen complex vacancies in both subsurface and interface regions and larger grain domains when compared with the pristine one. Consequently, the double exchange interaction is suppressed and the metallic-ferromagnetic state below Curie temperature turned into spin-glass insulating state. In contrast, the magnetic and resistivity measurements show that the oxygen treatment increases ferromagnetic phase volume, resulting in greater magnetization (MS) and improved magnetoresistivity properties below Curie temperature by improving the double exchange interaction. The threshold field to observe the training effect is decreased in oxygen treated film. In addition, the positron annihilation spectroscopy analysis exhibits fewer open volume defects in the subsurface region for oxygen treated film when compared with the pristine sample. These results unambiguously demonstrate that the oxygen treated film with significant spin memory and greater magnetoresistance can be a potential candidate for the future memristor applications.

Abstract
Einleitung Die katheterbezogene Lebensqualität (LQ) bei Nephrostomieträgern wurde bisher noch nie systematisch untersucht. Dies sollte nun erstmalig vergleichend mit einer ebenfalls externen Urinableitung, dem suprapubischen Katheter, geschehen. Methodik Das die katheterbezogene LQ untersuchende Assessment nach Mary Wilde wurde bei Patienten mit perkutaner Nephrostomie (PCN) in lebenslanger Intention und minimaler Liegedauer von 3 Monaten vorgelegt. Ergebnisse Es zeigte sich insgesamt bei 66 Patienten (davon 42 mit unilateraler PCN) mit einem Punktwert von median 4,0 auf einer Skala von 0–5 eine nur moderat eingeschränkte katheterbezogene LQ. Diese wurde insgesamt und in allen Domänen schlechter als bei Patienten mit suprapubischem Katheter (SPK) bewertet, bei denen sich ein Score von 4,3 im Median fand. Signifikant waren die Unterschiede in den Einzelitems „Gefühl der Erniedrigung“, „Konflikte mit ärztlichem oder pflegerischem Personal“, „Angst vor schmerzhaften Katheterwechseln“, „Gefühl als kranke Person“, „Behinderungen in Aktivitäten des täglichen Lebens“ und „Besorgnis, nicht alles tun zu können, was ich mag“. Ebenso ergaben sich bei PCN-Trägern signifikant häufiger Angst vor Katheterlecks und Uringeruch. Die Anzahl der einliegenden PCN und die Grunderkrankung spielten für die Beurteilung der LQ keine Rolle. Schlussfolgerung Erstmals wurde die katheterassoziierte LQ, die sich bei PCN-Trägern nur moderat eingeschränkt fand, mit einem validierten Assessment quantitativ eingeordnet. Die Angabe der Betroffenen, sich als „krank“ und in der Ausübung von Aktivitäten des täglichen Lebens „behindert“ zu fühlen und die Angst vor Urinleckagen und schmerzhaften Wechseln sollten Ansporn für eine sorgfältige Indikationsstellung und technisch korrekte Katheterwechsel sein.

Abstract
An investigation of the German consumer organisation "Stiftung Warentest" in 2017 confirmed significant deficiencies in the information, advice and supply of incontinence care products received by urinary incontinence patients. The German Society of Urology (DGU) thereupon drafted and later published guidelines concerning the consultation of patients in the context of incontinence care. Important aspects of the consultation process include the determination of the type of incontinence as well as its severity, clinical examination, and advice regarding possible curative treatments. However, the advice appointment takes centre stage and should ideally be conducted by a qualified person in a separate room granting sufficient privacy and time. Furthermore, repeated supply of a selection of samples for differing degrees and types of incontinence, accommodating the patient's individual preferences and anatomical features, is crucial in order to ensure optimal incontinence care. In the case of commercial health care service providers, transparency relating to the financial implications of e.g. expensive products is key, which is what has been intended by German health insurance providers. The new guidelines concerning urinary incontinence care consultation constitute a step towards the improvement and structuring of processes in the consultation regarding, and the supply of, incontinence care products.

Abstract
Luminescence probes that facilitate multimodal non-contact measurements of temperature are of particular interest due to the possibility of cross-referencing results across different readout techniques. This intrinsic referencing is an essential addition that enhances accuracy and reliability of the technique. A further enhancement of sensor performance can be achieved by using two luminescent ions acting as independent emitters, thereby adding in-built redundancy to non-contact temperature sensing, using a single readout technique. In this study we combine both approaches by engineering a material with two luminescent ions that can be independently probed through different readout modes of non-contact temperature sensing. The approach was tested using Al2O3 co-doped with Cr3+ and Mn4+, exhibiting sharp emission lines due to 2E → 4A2 transitions. The temperature sensing performance was examined by measuring three characteristics: temperature-induced changes of the intensity ratio of the emission lines, their spectral position, and the luminescence decay time constant. The processes responsible for the changes with temperature of the measured luminescence characteristics are discussed in terms of relevant models. By comparing temperature resolutions achievable by different modes of temperature sensing it is established that in Al2O3-Cr,Mn spectroscopic methods provide the best measurement accuracy over a broad temperature range. A temperature resolution better than ±2.8 K can be achieved by monitoring the luminescence intensity ratio (40-145 K) and the spectral shift of the R-line of Mn4+ (145-300 K range).

Abstract
Hintergrund Die Anlage eines transurethralen Dauerkatheters (DK) oder suprapubischen Harnblasenkatheters (SPK) in lebenslanger Indikation stellt einen Eingriff mit relevanten Komplikationen, Komorbiditäten und möglichen Auswirkungen auf die katheterassoziierte Lebensqualität des Betroffenen dar. Letztere wurde aber bisher noch nicht untersucht. Methodik Zur Anwendung kam ein validiertes Assessment zur katheterbezogenen Lebensqualität mit 25 Items in 5 Domänen. Befragt wurden im Rahmen eines Katheterwechsels Patienten mit einem DK oder SPK in lebenslanger Intention, die diesen mindestens 3 Monate trugen. Ergebnisse Fragebögen von 357 Patienten, davon 260 Männer und 97 Frauen, 193 mit SPK und 162 mit DK (2 ohne Angabe) lagen vor. Patienten mit DK waren mit 78,9 ± 11,1 Jahren signifikant älter als solche mit SPK mit 74,4 ± 12,6 Jahren (p < 0,001). Der mittlere Gesamtlebensqualitätsscore lag bei 4,1 ± 0,9 Punkten auf einer Skala von 1 (maximal beeinträchtigte Lebensqualität) bis 5 (keine Beeinträchtigung der Lebensqualität). Es zeigten sich u. a. mit niedrigeren Scores eine vermehrte Angst vor Katheterlecks, Angst vor Uringeruch und Harnwegsinfektionen und vor schmerzhaften Katheterwechseln. Diese Sorgen waren v. a. bei Frauen, solchen mit Harninkontinenz, Trägern eines Katheters ≥ 18 Ch und bei Patienten < 70 Jahren vorhanden. Frauen mit einem SPK wiesen eine schlechtere Bewertung ihrer Lebensqualität als Männer mit SPK auf. Schlussfolgerung Die gefundenen Ergebnisse sollten in die Aufklärung zu einer lebenslangen Katheterableitung einfließen bzw. im Kontext möglicher Alternativen wie z. B. einer operativen Desobstruktion oder einer Hilfsmittelversorgung mit dem Patienten bzw. Betreuungspersonen besprochen werden. Zusatzmaterial online Die Online-Version dieses Beitrags (10.1007/s00120-021-01642-1) enthält weitere Tabellen mit detaillierten Ergebnissen der Fragen der 5 abgefragten Domänen.

Abstract
The effect ofin situoxygen and vacuum annealings on the low bandwidth manganite Gd1-xCaxMnO3(GCMO) thin film withx= 0.4 was investigated. Based on the magnetic measurements, the AFM-FM coupling is suppressed by the vacuum annealing treatment via destroying the double exchange interaction and increasing the unit cell volume by converting the Mn4+to the Mn3+. Consequently, resistance increases significantly compared to pristine film. The results are explained by a model obtained from the positron annihilation studies, where the vacuum annealing increased the annihilation lifetime in A and B sites due to the formation of vacancy complexesVA,B-VO, which was not the case in the pristine sample. The positron annihilation analysis indicated that most of the open volume defects have been detected in the interface region rather than on the subsurface layer and this result is confirmed by detailed x-ray reflection analysis. On the other hand, the effect of oxygen annealing on the unit cell volume and magnetization was insignificant. This is in agreement with positron annihilation results which demonstrated that the introduction of oxygen does not change the number of cation vacancies significantly. This work demonstrates that the modification of oxygen vacancies and vacancy complexes can tune magnetic and electronic structure of the epitaxial thin films to provide new functionalities in future applications.

Abstract
OBJECTIVE To determine the effectiveness of closed incision negative pressure wound therapy (NPWT) compared with standard dressings in preventing surgical site infection (SSI) in obese women undergoing caesarean section. DESIGN Multicentre, pragmatic, randomised, controlled, parallel group, superiority trial. SETTING Four Australian tertiary hospitals between October 2015 and November 2019. PARTICIPANTS Eligible women had a pre-pregnancy body mass index of 30 or greater and gave birth by elective or semi-urgent caesarean section. INTERVENTION 2035 consenting women were randomised before the caesarean procedure to closed incision NPWT (n=1017) or standard dressing (n=1018). Allocation was concealed until skin closure. MAIN OUTCOME MEASURES The primary outcome was cumulative incidence of SSI. Secondary outcomes included depth of SSI (superficial, deep, or organ/body space), rates of wound complications (dehiscence, haematoma, seroma, bleeding, bruising), length of stay in hospital, and rates of dressing related adverse events. Women and clinicians were not masked, but the outcome assessors and statistician were blinded to treatment allocation. The pre-specified primary intention to treat analysis was based on a conservative assumption of no SSI for a minority of women (n=28) with missing outcome data. Post hoc sensitivity analyses included best case analysis and complete case analysis. RESULTS In the primary intention to treat analysis, SSI occurred in 75 (7.4%) women treated with closed incision NPWT and in 99 (9.7%) women with a standard dressing (risk ratio 0.76, 95% confidence interval 0.57 to 1.01; P=0.06). Post hoc sensitivity analyses to explore the effect of missing data found the same direction of effect (closed incision NPWT reducing SSI), with statistical significance. Blistering occurred in 40/996 (4.0%) women who received closed incision NPWT and in 23/983 (2.3%) who received the standard dressing (risk ratio 1.72, 1.04 to 2.85; P=0.03). CONCLUSION Prophylactic closed incision NPWT for obese women after caesarean section resulted in a 24% reduction in the risk of SSI (3% reduction in absolute risk) compared with standard dressings. This difference was close to statistical significance, but it likely underestimates the effectiveness of closed incision NPWT in this population. The results of the conservative primary analysis, multivariable adjusted model, and post hoc sensitivity analysis need to be considered alongside the growing body of evidence of the benefit of closed incision NPWT and given the number of obese women undergoing caesarean section globally. The decision to use closed incision NPWT must also be weighed against the increases in skin blistering and economic considerations and should be based on shared decision making with patients.

Abstract
The excess energy emitted during the positronium (Ps) formation in condensed matter may be released as light. Spectroscopic analysis of this light can be a new method of studying the electronic properties of materials. We report the first experimental attempt, according to our knowledge, to verify the existence of this emission process. As a result, the possibility of the emission of photons during Ps formation is within the experimental uncertainty in two different solids: an n-alkane and porous silica. However, it seems that the Ps formation on the alkane surface is not accompanied by the emission of photons with energy in the detection range of 1.6-3.8 eV. Various processes that can influence the energy of the photon emitted during the Ps formation are discussed to elucidate this issue. To aid future experiments, equations were developed to estimate the expected ratio of light emission events to annihilation events with the presence or absence of a photon during the Ps formation.

Abstract
Sarcomas are a heterogeneous group of malignancies with mesenchymal lineage differentiation. The discovery of neurotrophic tyrosine receptor kinase (NTRK) gene fusions as tissue-agnostic oncogenic drivers has led to new personalized therapies for a subset of patients with sarcoma in the form of tropomyosin receptor kinase (TRK) inhibitors. NTRK gene rearrangements and fusion transcripts can be detected with different molecular pathology techniques, while TRK protein expression can be demonstrated with immunohistochemistry. The rarity and diagnostic complexity of NTRK gene fusions raise a number of questions and challenges for clinicians. To address these challenges, the World Sarcoma Network convened two meetings of expert adult oncologists and pathologists and subsequently developed this article to provide practical guidance on the management of patients with sarcoma harboring NTRK gene fusions. We propose a diagnostic strategy that considers disease stage and histologic and molecular subtypes to facilitate routine testing for TRK expression and subsequent testing for NTRK gene fusions.

Abstract
OBJECTIVES The objective of this study was to compare paediatric emergency airway management strategies in the simulation lab and operating room environments. METHODS This was a two-part cluster cross-over randomised trial including simulation lab and operating room environments conducted between January 2017 and June 2018 in Portland, Oregon, USA. In simulated infant cardiac arrests, paramedic students placed an endotracheal tube, an i-gel or a laryngeal mask airway in random order. In the operating room, paramedic students placed a laryngeal mask airway or i-gel device in random order in sequential patients. The primary outcome for both portions of the study was time to ventilation. In the operating room portion, we also evaluated leak pressures and average initial tidal volumes. RESULTS There were 58 paramedic students who participated in the simulation lab and 22 who participated in the operating room study. The mean time to airway placement in the simulation lab was 48.5 s for the i-gel, 68.9 s for the laryngeal mask and 129.5 s for the endotracheal tube. In the operating room, mean time to i-gel placement was 34.3 s with 45.2 s for the laryngeal mask. In multivariable analysis of the simulation study, the laryngeal mask and i-gel were significantly faster than the endotracheal tube, and the i-gel was faster than the laryngeal mask. In the operating room, there was no significant difference in time to placement, leak pressure and average volume of the first five breaths between the i-gel and laryngeal mask. CONCLUSIONS We found that paramedic students were able to place supraglottic devices rapidly with high success rates in simulation lab and operating room environments. Supraglottic devices, particularly the i-gel, were rated as easy to use. The i-gel may be easiest to use since it lacks an inflable cuff and requires fewer steps to place.

Abstract
The nondestructive investigation of single vacancies and vacancy clusters in ion-irradiated samples requires a depth-resolved probe with atomic sensitivity to defects. The recent development of short-pulsed positron beams provides such a probe. Here, we combine depth-resolved Doppler broadening and positron annihilation lifetime spectroscopies to identify vacancy clusters in ion-irradiated Fe and measure their density as a function of depth. Despite large concentrations of dislocations and voids in the pristine samples, positron annihilation measurements uncovered the structure of vacancy clusters and the change in their size and density with irradiation dose. When combined with transmission electron microscopy measurements, the study demonstrates an association between the increase in the density of small vacancy clusters with irradiation and a remarkable reduction in the size of large voids. This, previously unknown, mechanism for the interaction of cascade damage with voids in ion-irradiated materials is a consequence of the high porosity of the initial microstructure.

Abstract
PURPOSE This work describes the integration of the M6 Cyberknife in the Moderato Monte Carlo platform, and introduces a machine learning method to accelerate the modelling of a linac. METHODS The MLC-equipped M6 Cyberknife was modelled and integrated in Moderato, our in-house platform offering independent verification of radiotherapy dose distributions. The model was validated by comparing TPS dose distributions with Moderato and by film measurements. Using this model, a machine learning algorithm was trained to find electron beam parameters for other M6 devices, by simulating dose curves with varying spot size and energy. The algorithm was optimized using cross-validation and tested with measurements from other institutions equipped with a M6 Cyberknife. RESULTS Optimal agreement in the Monte Carlo model was reached for a monoenergetic electron beam of 6.75 MeV with Gaussian spatial distribution of 2.4 mm FWHM. Clinical plan dose distributions from Moderato agreed within 2% with the TPS, and film measurements confirmed the accuracy of the model. Cross-validation of the prediction algorithm produced mean absolute errors of 0.1 MeV and 0.3 mm for beam energy and spot size respectively. Prediction-based simulated dose curves for other centres agreed within 3% with measurements, except for one device where differences up to 6% were detected. CONCLUSIONS The M6 Cyberknife was integrated in Moderato and validated through dose re-calculations and film measurements. The prediction algorithm was successfully applied to obtain electron beam parameters for other M6 devices. This method would prove useful to speed up modelling of new machines in Monte Carlo systems.

Abstract
Abstract
Objective
Children with traumatic brain injury (TBI) requiring neurocritical care are at high risk for neurocognitive, emotional, physical, and psychosocial difficulties, collectively known as Post-Intensive Care Syndrome. Our study sought to characterize parent ratings of emotional functioning in the acute recovery phase based upon mechanism of injury.
Method
Twenty children (Mdn = 12.6 years, IQR = 9-15; 65% male) were screened as part of a multidisciplinary follow-up clinic 1-month following hospital discharge. Emotional functioning was assessed using PROMIS Parent Proxy Report for Anxiety and Depression. A brief neurocognitive battery estimated presence of cognitive impairment. MANCOVA was used to compare emotional functioning across injury mechanism (high velocity injury [HVI], 65%; fall, 35%).
Results
Groups did not differ on age, gender, and presence of cognitive impairment. After controlling for severity, mechanism of injury had a significant effect on both anxiety (p = .026) and depression (p = .004). The HVI group had mildly elevated anxiety (M = 50.5, SD = 12.2) and depression (M = 54.2, SD = 10.6) scores, while the fall group had anxiety (M = 38.0, SD = 6.2) and depression (M = 39.0, SD = 7.3) scores within normal limits.
Conclusions
In the acute recovery phase following TBI, anxiety and depression symptoms are more common after HVI than falls, even when controlling for severity of injury. The HVI group includes injuries resulting from motor vehicle accidents which may have a broader impact on the family and may explain higher rates of emotional distress in this patient group compared to other mechanisms of TBI. Additional research is needed to further explore variables related to emotional functioning following TBI and how they change over the course of recovery.

Abstract
Modifications of magnetic and magneto-optical properties of Pt/Co(d Co )/Pt upon Ar+ irradiation (with energy 1.2, 5 and 30 keV) and fluence, F at the range from 2 · 1013-2 · 1016 Ar+ cm-2) were studied. Two 'branches' of increased perpendicular magnetic anisotropy (PMA) and enhanced magneto-optical response are found on 2D (d Co , F) diagrams. The difference in F between 'branches' is driven by ion energy. Structural features correlated with magnetic properties have been analysed thoroughly by x-ray diffraction, Rutherford backscattering spectrometry and positron annihilation spectroscopy. Experimental results are in agreement with TRIDYN numerical calculations of irradiation-induced layers intermixing. Our work discusses particularly structural factors related to crystal lattice defects and strain, created and modified by irradiation, co-responsible for the increase in the PMA.

Abstract
Iron is very important element for functioning of the brain. Its concentration changes with aging the brain or during disease. The aim of our work was the histological examination of content of ferritin and free iron (unbound) in brain cortex in association with Aβ plaques from their earliest stages of accumulation in amyloid plaque forming APP/PS1 transgenic mice. Light microscopy revealed the onset of plaques formation at 8-monthage. Detectable traces of free iron and no ferritin were found around plaques at this age, while the rate of their accumulation in and around Aβ plaques was elevated at 13 months of age. Ferritin accumulated mainly on the edge of Aβ plaques, while the smaller amount of free iron was observed in the plaque-free tissue, as well as in and around Aβ plaques. We conclude that free iron and ferritin accumulation follows the amyloid plaques formation. Quantification of cortical iron and ferritin content can be an important marker in the diagnosis of Alzheimer’s disease.
