Abstract
BACKGROUND Preventative strategies that minimize hemodialysis access complications remain limited. OBJECTIVE This study aimed to address this gap by developing a Caprine cannulation model to investigate the impact of repeated cannulations on vascular access patency rates. RESEARCH DESIGN AND MEASURES In this pilot study, a meta-analysis was conducted using experimental control data from four trials to explore the impact of Caprine breed (independent variable) on the dependent variables that affect hemodialysis cannulation, including AVF growth, AVF depth, and flow rate. SUBJECTS Arteriovenous Fistulas (AVFs) were created using the carotid artery and jugular vein in the necks of seven goats from the French alpine, dwarf, and pygmy breeds. All seven AVFs exhibited vessel remodeling patterns similar to that observed in humans and remained patent, enabling hemodialysis access over the 6 month study. RESULTS Over the course of 18 weeks, a total of 291 cannulations were completed using standard 15 g dialysis needles without complications demonstrating the feasibility of using the Caprine species as a cannulation model. The ease of access coupled with the animals' cooperative behavior further contributes to the suitability of the Caprine species for hemodialysis investigations. Notably, no infections or clinically significant incidents were observed throughout the study. CONCLUSIONS The stability of AVF patency and flow underscores the viability and potential of the Caprine species animal model as a valuable research platform for exploring interventions aimed at improving vascular access survival in hemodialysis patients.

Abstract
Nodule-specific cysteine-rich (NCR) peptides, encoded in the genome of the Mediterranean legume Medicago truncatula (barrelclover), are known to regulate plant-microbe interactions. A subset of computationally derived 20-mer peptide fragments from 182 NCR peptides was synthesized to identify those with activity against the unculturable vascular pathogen associated with citrus greening disease, 'Candidatus Liberibacter asiaticus' (CLas). Grounded in a design of experiments framework, we evaluated the peptides in a screening pipeline involving three distinct assays: a bacterial culture assay with Liberibacter crescens, a CLas-infected excised citrus leaf assay, and an assay to evaluate effects on bacterial acquisition by the nymphal stage of hemipteran vector Diaphorina citri. A subset of the 20-mer NCR peptide fragments inhibits both CLas growth in citrus leaves and CLas acquisition by D. citri. Two peptides induced higher levels of D. citri mortality. These findings reveal 20-mer NCR peptides as a new class of plant-derived biopesticide molecules to control citrus greening disease.

Abstract
Machine learning (ML) approaches could expand the usefulness and application of implementation science methods in clinical medicine and public health settings. The aim of this viewpoint is to introduce a roadmap for applying ML techniques to address implementation science questions, such as predicting what will work best, for whom, under what circumstances, and with what predicted level of support, and what and when adaptation or deimplementation are needed. We describe how ML approaches could be used and discuss challenges that implementation scientists and methodologists will need to consider when using ML throughout the stages of implementation.

Abstract
The landscape of scientific publishing is experiencing a transformative shift toward open access, a paradigm that mandates the availability of research outputs such as data, code, materials, and publications. Open access provides increased reproducibility and allows for reuse of these resources. This article provides guidance for best publishing practices of scientific research, data, and associated resources, including code, in The American Phytopathological Society journals. Key areas such as diagnostic assays, experimental design, data sharing, and code deposition are explored in detail. This guidance aligns with that observed by other leading journals. We hope the information assembled in this paper will raise awareness of best practices and enable greater appraisal of the true effects of biological phenomena in plant pathology.

Abstract
The genus Coguvirus, a recently established genus in the family Phenuiviridae, includes several species whose members infect both woody and herbaceous hosts, suggesting a broader host range and wider distribution than previously. To gain insights into the epidemiology and biology of coguviruses, a polyvalent reverse transcription-PCR assay using degenerate primers was developed. The specificity of the assay for coguviruses was confirmed by testing citrus and apple plants infected by previously reported coguviruses and/or several unrelated viruses. The expected 236-bp amplicon was obtained from citrus, apple, pear, watermelon, and several species of the family Brassicaceae. Sequencing of the PCR amplicons allowed the identification, for the first time in Italy and/or Europe, of several coguviruses in multiple hosts, confirming the effectiveness of the assay. Moreover, a new virus, tentatively named Brassica oleracea Torzella virus 1 (BoTV1), was detected in several plants of Torzella cabbage. The complete +genome of BoTV1, determined by high-throughput sequencing and 5' rapid amplification of cDNA ends, revealed that it has the typical molecular features of coguviruses and fulfils the current criteria to be classified as a member of a new species, for which the tentative name Coguvirus torzellae is proposed. The same polyvalent assay was also used to investigate and confirm that BoTV1 is transmitted through seeds in black cabbage, thus providing the first evidence on the relevance of this natural transmission mode in the epidemiology of coguviruses.

Abstract
Since 2010, there has been little published data on the state of equipment and infrastructure in veterinary radiation oncology clinical practice. These data are important not only to identify the status and use of technology within the veterinary radiation oncology community but also to help identify the extent of medical physics support. The purpose of our study is to report findings from a survey of veterinary radiation oncologists in the USA, Canada, and select centers outside of North America in 2022. A 40-question survey covering topics such as type of radiotherapy equipment, techniques offered, treatment planning systems and dose calculation algorithms, special techniques, board-certified radiation oncologists and residents, and extent of medical physics support was distributed through an online survey tool. Results from 40 veterinary radiation oncology institutions, with equipment explicitly used for veterinary care, suggest that the current state of practice is not dissimilar to what currently exists in human radiation oncology facilities; techniques and technologies commonly employed include flattening filter-free mode megavoltage beams, volumetric arc therapy, daily cone-beam computed tomography, image-guided radiation therapy, and sophisticated dose calculation algorithms. These findings suggest the need for modern radiation oncology acceptance testing, commissioning, and quality assurance programs within the veterinary community. The increase in veterinary radiation oncology residency positions and increasing sophistication of equipment suggests that increased levels of standardized medical physics support would benefit the veterinary radiation oncology community.

Abstract
Extracellular vesicles (EVs) secreted by all cell types are involved in the cell-to-cell transfer of regulatory factors that influence cell and tissue phenotypes in normal and diseased tissues. EVs are thus a rich source of biomarker targets for assays that analyze blood and urinary EVs for disease diagnosis. Sensitive biomarker detection in EVs derived from specific cell populations is a key major hurdle when analyzing complex biological samples, but innovative approaches surveyed in this Perspective can streamline EV isolation and enhance the sensitivity of EV detection procedures required for clinical application of EV-based diagnostics and therapeutics, including nanotechnology and microfluidics, to achieve EV characterizations. Finally, this Perspective also outlines opportunities and challenges remaining for clinical translation of EV-based assays.

Abstract
Primary graft dysfunction (PGD) is a common complication after lung transplantation. A plethora of contributing factors are known and assessment of donor lung function prior to organ retrieval is mandatory for determination of lung quality. Specialized centers increasingly perform ex vivo lung perfusion (EVLP) to further assess lung functionality and improve and extend lung preservation with the aim to increase lung utilization. EVLP can be performed following different protocols. The impact of the individual EVLP parameters on PGD development, organ function and postoperative outcome remains to be fully investigated. The variables relate to the engineering and function of the respective perfusion devices, such as the type of pump used, functional, like ventilation modes or physiological (e.g. perfusion solutions). This review reflects on the individual technical and fluid components relevant to EVLP and their respective impact on inflammatory response and outcome. We discuss key components of EVLP protocols and options for further improvement of EVLP in regard to PGD. This review offers an overview of available options for centers establishing an EVLP program and for researchers looking for ways to adapt existing protocols.

Abstract
Protein-protein interactions orchestrate plant development and serve as crucial elements for cellular and environmental communication. Understanding these interactions offers a gateway to unravel complex protein networks that will allow a better understanding of nature. Methods for the characterization of protein-protein interactions have been around for a long time, yet the complexity of some of these interactions fuels the development of new techniques that provide a better understanding of the underlying dynamics. In many cases, the application of these techniques is limited by the nature of the available sample. While some methods require an in vivo set up, others solely depend on protein sequences to study protein-protein interactions via an in silico set up. The vast amount of techniques available to date calls for a way to select the appropriate tools for the study of specific interactions. Here, we classify widely spread tools and new emerging techniques for the characterization of protein-protein interactions based on sample requirements while providing insights into the information that they can potentially deliver. We provide a comprehensive overview of commonly used techniques and elaborate on the most recent developments, showcasing their implementation in plant research.

Abstract
This study aimed to develop and validate "the Imprint method,", a technique for sampling microbes from chronic wounds while preserving their two-dimensional spatial organization. We used nylon filters to sample bacteria and compared with sampling using Eswabs in 12 patients. The Imprint method identified a mean of 0.93 unique species more than Eswab (4.3 ± 2.2 and 3.4 ± 1.4 unique species, respectively; mean ± SD; n = 30). Accuracy between the Eswab and the Imprint method was 93.2% and in cases of disagreement between methods, Imprint had a higher sensitivity in 6/8 of the most prevalent species. In vitro validation confirmed that the Imprint method could transfer bacterial colonies while replicating their two-dimensional organization and the area covered by bacteria on the plate sampled. Clinical testing demonstrated that the imprint method is a rapid and feasible technique that identified more unique bacterial species than Eswab with a good agreement between methods but that Imprint was better at detecting important pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa. The Imprint method is a novel technique that cultures and records the two-dimensional organization of microbes, providing an alternative or supplement to conventional surface culture using Eswab.

Abstract
Aim and methodology The aim of the study was to describe the preferred cataract surgery practices among Moroccan ophthalmologists and compare them with practices in other countries. An online survey consisting of 29 multiple-choice questions was sent to Moroccan ophthalmologists. The questions were centered on the preferred cataract surgical practices of the participants. All the data obtained were collected and analyzed. Results A total of 276 participants responded to the survey. Of these, 178 (64,50%) were in the age group of 31-50 years. The visual acuity for which the operative indication was made was 4/10 for 144 (52.4%) participants). The most popular type of anesthesia was topical, reported by 172 (62.4%). Stop-and-chop was the most used technique for routine cataract surgeries, while hydroprolapse of the nucleus was the leading technique for soft cataracts. The two measures are considered crucial for postoperative endophthalmitis prophylaxis: Povidone-iodine instillation into the conjunctival sac and intracameral antibiotics were performed by 267 (97%) and 276 (100%) participants, respectively. Nonsteroidal anti-inflammatory drugs were prescribed by only 128 (46.5%) surgeons. Conclusion This study provides some insight into the present cataract surgery techniques in Morocco, which might differ considerably from one country to another. Studies in various countries need to be undertaken to develop a consensus and reach some evidence-based patterns. This study may serve as a guide for young surgeons starting their careers based on what the standard procedures are among their seniors and peers.

Abstract
AIM Use of microaxial mechanical circulatory support (MCS) has been reported for severe graft rejection or dysfunction after heart transplantation (HTx). We aimed to assess utilization patterns of microaxial MCS after HTx in adolescents (ages 18 and younger) and adults (ages 19 and older). METHODS Electronic search was performed to identify all relevant studies on post-HTx use of microaxial support in adults and adolescents. A total of 18 studies were selected and patient-level data were extracted for statistical analysis. RESULTS All patients (n=23), including adults (n=15) and adolescents (n=8), underwent Impella (Abiomed, Danvers, MA) microaxial MCS after HTx. Median age was 36 [IQR 18-56] years (Adults, 52 [37-59]; adolescents, 16 [15-17]). Primary right ventricular graft dysfunction was an indication exclusively seen in the adults 40% (6/15), while acute graft rejection was present in 46.7% (7/15) of adults. Median time after transplant was 9 [0-32] months (Adults, 4 [0-32]; adolescents, 11 [4.5, 45]). Duration of Impella support was comparable between adults and adolescents (5 [2.5-8] vs 6 [5-8] days, p = 0.38). Overall improvement was observed both in median LV ejection fraction (23.5% [11.3-28] to 42% [37.8-47.3], p < 0.01) and cardiac index (1.8 [1.2-2.6] to 3 [2.5-3.1], p < 0.01). Retransplantation was required in four adolescents (50%, 4/8). Survival to discharge was achieved by 60.0% (9/15) of adults and 87.5% (7/8) of adolescents respectively (p = 0.37). CONCLUSION Indications for microaxial MCS appear to vary between adult and adolescent patients. Overall improvement in LVEF and cardiac index was observed, however, with suboptimal survival to discharge.

Abstract
For centuries, ancient lineages have consumed psychedelic compounds from natural sources. In the modern era, scientists have since harnessed the power of computational tools, cellular assays, and behavioral metrics to study how these compounds instigate changes on molecular, cellular, circuit-wide, and system levels. Here, we provide a brief history of psychedelics and their use in science, medicine, and culture. We then outline current techniques for studying psychedelics from a pharmacological perspective. Finally, we address known gaps in the field and potential avenues of further research to broaden our collective understanding of physiological changes induced by psychedelics, the limits of their therapeutic capabilities, and how researchers can improve and inform treatments that are rapidly becoming accessible worldwide.

Abstract
BACKGROUND/OBJECTIVE Laryngeal electromyography (LEMG) is a useful diagnostic test in the evaluation of vocal fold paralysis (VFP). This study investigates factors that can make LEMG challenging to perform. METHODS Patients with subacute unilateral VFP presented for LEMG were prospectively enrolled. Demographic data including BMI, previous neck surgery, and anatomic factors were collected. Patient-reported pain related to the procedure was recorded on a visual analogue scale (VAS). Electromyographer and otolaryngologist recorded a consensus rating of the perceived difficulty in performing the test and confidence in using the results for clinical decision-making. RESULTS A total of 111 patients (56.8% female) were enrolled between August 2015 and August 2018. The mean age was 55 ± 14 years, and the average body mass index (BMI) was 28.5 ± 6.4. The mean patient-reported VAS score for pain was 35 ± 24. Notably, 31.2% of the tests were considered "very easy," 32.1% were considered "mildly challenging" and 23.9% and 12.8% were considered "moderately challenging" and "extremely challenging," respectively, by the clinicians. Common factors affecting LEMG difficulty included poorly palpable surface anatomy (50.5%) and patient intolerance (15.6%). Clinicians felt confident in 76.1% of the test findings. Bivariate analyses showed that prior neck surgery is associated with elevated VAS (p = 0.02), but clinician-perceived difficulty of performing the test is not associated with elevated VAS scores (p = 0.55). CONCLUSIONS Majority of LEMG tests are well tolerated by patients. Physicians reported more confidence using LEMG for clinical decision-making when the test was easier to perform. Difficult surface anatomy and patient intolerance affects clinician confidence in integrating the test results with clinical care. LEVEL OF EVIDENCE 3 Laryngoscope, 134:831-834, 2024.

Abstract
The oomycete Phytophthora capsici is a destructive pathogen infecting more than 50 plant species and is one of the most serious threats to cucurbit production. Phytophthora blight caused by Phytophthora capsici can affect all plant growth stages, and fungicides and cultural controls are used to limit losses. Dissecting pathogen virulence and fungicide resistance can provide insights into pathogenic mechanisms and inform effective management practices to control P. capsici. In this study, we assessed virulence, mefenoxam sensitivity, and genetic diversity of nine P. capsici populations collected from Cucurbitaceae, Solanaceae, and Fabaceae host families in Michigan from 2002 to 2016. We developed 992 simple sequence repeats (SSRs) in the P. capsici genome and identified 60 SSRs located within or close to RXLR-class (Arginine-any amino acid-Leucine-Arginine) effectors and 29 SSRs within or close to effector CRN (CRinkling and Necrosis) family protein, which represent 62 RXLR and 34 putative CRNs. Population structure analysis shows that mefenoxam resistance was not associated with the year of collection, host type, or location, but there were significant differences in virulence among the populations. Using the general linear model and mixed linear model-based association analyses with all effector-related SSR markers, we identified four SSR markers significantly associated with at least one of the virulence-related parameters. Of these, one (Pce_SC18) was in a predicted CRN effector and had high identity with the putative PhCRN37 effector in the pathogen Plasmopara halstedii, which can be further verified for virulence identification in P. capsici.

Abstract
Primary hepatobiliary cancers (PHCs), which mainly include hepatocellular carcinoma (HCC) and biliary tract cancers (BTCs), are mostly diagnosed in the advanced stage and are not candidates for curative surgery or ablation, resulting in a dismal prognosis. Targeted therapies with or without programmed death receptor 1 (PD-1)/PD-L1 inhibitors have been incorporated into first-line treatments for advanced HCC. Systemic chemotherapy is still the mainstay treatment for advanced BTCs, and combining it with PD-1/PD-L1 inhibitors has resulted in prolonged patient survival. Intra-arterial therapies, including trans-arterial chemoembolization, selective internal radiation therapy, and hepatic arterial infusion chemotherapy (HAIC), have been explored and used for advanced hepatobiliary cancers for many years with positive results, particularly when combined with systemic treatments. Recently, an increasing number of phase II/III trials have demonstrated the efficacy and safety of HAIC for the treatment of advanced HCC with portal vein tumor thrombosis and/or a large tumor burden, for the neoadjuvant and adjuvant treatment of HCC with high-risk factors, and for treating advanced intrahepatic and perihilar cholangiocarcinoma. However, the techniques and regimens used for HAIC are diverse and differ greatly between various regions and centers worldwide. This review focuses on these diverse techniques and regimens, as well as the updated evidence on HAIC regarding the treatment of PHCs.

Abstract
Vegetables and fruits are highly perishable agricultural commodities cultivated all over the world. However, inadequate handling practices have led to significant postharvest losses of these agricultural commodities, as well as the wastage of valuable resources, such as time and money. Hence, it can be observed that cultivators often experience significant financial setbacks as a result of inadequate comprehension regarding the nature and origins of these losses, insufficient preservation practices, and ineffective approaches to transportation and marketing. In addition, the utilization of suitable chemical agents during both the pre- and postharvest phases has the potential to prolong the shelf life of agricultural products. This preservation technique safeguards vegetables and fruits from pathogenic organisms and other forms of environmental harm, thereby enabling their availability for an extended duration. Therefore, this review proposes a methodology for managing fruits and vegetables postharvest to minimize losses and optimize returns.

Abstract
The incidence of breast cancer has exhibited an annually increasing trend, and the disease has become the most common malignant tumour worldwide. Currently, the primary treatment for breast cancer is surgical resection. However, metastatic recurrence is the main cause of cancer-related death in this patient population. Various factors are associated with breast cancer prognosis, and anaesthesia-induced changes in the tumour microenvironment have attracted increasing attention. To date, however, it remains unclear whether anaesthetic drugs have a positive or negative impact on cancer outcomes after surgery. The present article reviews the effects of different anaesthetics on the postoperative prognosis of breast cancer surgery to guide the choice of anaesthetic technique(s) and agents for such patients.

Abstract
Background Laparoscopic exploration is currently considered the gold standard for managing nonpalpable intraabdominal testes. The problem of short vascular pedicle is addressed in Fowler-Stephen (FS) technique by the division of testicular vessels and in Shehata technique (ST) by traction on testicular vessels. There is a lack of the consensus among pediatric surgeons on the choice of one technique over other. This analysis compares the reported outcomes of staged laparoscopic orchidopexy by ST with the time tested FS technique in managing high intraabdominal undescended testis. Materials and Methods The present systematic review and meta-analysis was conducted as per the preferred reporting items for the systematic review and meta-analyses guidelines. Only randomized controlled trials and comparative studies were included. The primary outcomes compared were the incidence of testicular atrophy, testicular retraction/ascent rate, and operative time of Stage I and Stage II orchidopexy. Results The present analysis was based on three randomized studies with a total of 119 undescended testes in 117 patients satisfying the inclusion criteria. The operative time was less in Stage I FS technique; however, there was no statistically significant difference in operative time of both procedures during the Stage II laparoscopic orchidopexy. Pooled analysis of postintervention testicular atrophy, testicular retraction rate, and duration of postoperative hospitalization showed no difference between both procedures. Conclusion Both FS and STs are comparable in terms of postintervention testicular atrophy, testicular retraction/ascent; however, the mean operative time is significantly less with FS technique in Stage I laparoscopic orchidopexy.

Abstract
Context Minimally invasive management (laparoscopic/robot assisted) is currently the standard of care for managing pelvi ureteric junction obstruction (PUJO). Open techniques of management of PUJO are well described in literature. However, there appears to be relative lack of description of minimally invasive techniques in the literature. Objective This article is aimed at describing in detail, with images, the various techniques and modifications in laparoscopic or robot-assisted management of PUJO. Evidence Acquisition A review of literature on PubMed was performed and all articles which detailed any technique of minimally invasive pyeloplasty were included. Evidence Synthesis The various techniques of minimally invasive pyeloplasty as well as the authors' techniques are compiled and described in detail with intraoperative images. Conclusions Operative techniques of minimally invasive pyeloplasty are not well described in literature. We have attempted to present a comprehensive resource of different techniques of minimally invasive pyeloplasty and the clinical scenarios in which they may be appropriate. This should prove to be a useful reference to the practicing urologist. Patient Summary In this paper, we have compiled the various surgical techniques of treating obstruction at the PUJ of the kidney along with intraoperative photograph.

Abstract
Ectopic variceal bleeding is a potentially under recognized source of gastrointestinal (GI) hemorrhage. While vascular complications following pancreatic transplant are relatively common, the development of symptomatic ectopic venous varices has rarely been reported. We report two patients with a remote history of simultaneous kidney pancreas transplant (SPK) presenting two decades after transplant with an occult GI bleed. In both cases, a lengthy diagnostic course was required. The varices were treated with coil embolization via transhepatic approach. Our findings add to the limited literature on this topic and aid in the recognition, diagnosis, and management of this unusual presentation.

Abstract
OBJECTIVE The current Instructions for Use (IFU) of cyanoacrylate closure (CAC) is to start initial injection with the catheter tip positioned 5 cm distal to the sapheno-femoral junction (SFJ) to prevent endovenous glue-induced thrombosis (EGIT). However, this defensive design is responsible for the relatively long stump length. Although clinical studies on the long-term recurrence rate are still lacking, the long stump length can predict a higher long-term recurrence rate compared to other surgical methods. The author developed a novel surgical technique that can overcome the weakness of CAC, and the initial outcomes of this technique are described in this article. METHODS This study retrospectively reviewed 25 great saphenous vein (GSV) in 20 patients who underwent CAC for incompetent GSV at our hospital. The procedure from puncturing the GSV to insertion of the catheter is the same as the conventional method. Place the catheter tip 2-3 cm below the SFJ before cyanoacrylate injection. After confirming the position of the SFJ with the longitudinal view of the ultrasound, press the GSV directly above the SFJ transversely with the second to fifth fingertips of the left hand. Then, the ultrasound probe is placed against the distal part of the fingertips, and CA injection is performed while GSV is monitored in real time. RESULTS The mean stump length immediately after surgery was 19.3 (± 7.8) mm, with a range of .0-38.4 mm. The mean stump length after 1 week was 12.3 (± 7.4) mm and the range was .1-35.4 mm. The mean stump length after 1 month was 15.4 (± 10.1) mm, and the range was .0-35.4 mm. There was no case with EGIT or recanalization. CONCLUSIONS The author confirmed the possibility of safely reducing stump length with this novel surgical technique, and expect that this method can help overcome the weakness of CAC.

Abstract
As a step towards implementing non-aversive handling techniques at a big mouse breeding facility in Germany, tunnel handling was introduced in a breeding unit comprising three inbred mouse strains. To assess whether tunnel handling would be feasible for the animal technicians in their everyday work and beneficial for the mice when being handled during weekly cage change only, the behaviour of tunnel- and tail-handled animals of both sexes was examined before, during and after the handling events over a period of nine weeks. Moreover, the time expenditure was compared between both handling techniques. It was possible to use the tunnel in all three mouse strains. However, the impact of the handling techniques on the behavioural parameters investigated in the present study were strain-specific. All behavioural parameters suggested that NZW mice benefited the most from tunnel handling. The results obtained from Hello Kitty and WNK mice were ambiguous, which may suggest that a brief handling session during the cage clean may have not been sufficient to habituate them to the process of handling. It took the animal technicians approximately 3 seconds longer per mouse when using a tunnel. The strain-specific results should encourage researchers to share their experiences with non-aversive handling techniques in different mouse strains, for example, along with their research articles.

Abstract
BACKGROUND When trying to be more physically active, preparing for possible barriers by considering potential coping strategies increases the likelihood of plan enactment. Digital interventions can support this process by providing personalized recommendations for coping strategies, but this requires that possible coping strategies are identified and classified. Existing classification systems of behavior change, such as the compendium of self-enactable techniques, may be reused to classify coping strategies in the context of physical activity (PA) coping planning. OBJECTIVE This study investigated whether coping strategies created by a student population to overcome barriers to be physically active can be mapped onto the compendium of self-enactable techniques and which adaptations or additions to the frameworks are needed. METHODS In total, 359 Flemish university students created action and coping plans for PA for 8 consecutive days in 2020, resulting in 5252 coping plans. A codebook was developed iteratively using the compendium of self-enactable techniques as a starting point to code coping strategies. Additional codes were added to the codebook iteratively. Interrater reliability was calculated, and descriptive statistics were provided for the coping strategies. RESULTS Interrater reliability was moderate (Cohen κ=0.72) for the coded coping strategies. Existing self-enactable techniques covered 64.6% (3393/5252) of the coded coping strategies, and added coping strategies covered 28.52% (n=1498). The remaining coping strategies could not be coded as entries were too vague or contained no coping strategy. The added classes covered multiple ways of adapting the original action plan, managing one's time, ensuring the availability of required material, and doing the activity with someone else. When exploring the data further, we found that almost half (n=2371, 45.1%) of the coping strategies coded focused on contextual factors. CONCLUSIONS The study's objective was to categorize PA coping strategies. The compendium of self-enactable techniques addressed almost two-thirds (3393/5252, 64.6%) of these strategies, serving as valuable starting points for classification. In total, 9 additional strategies were integrated into the self-enactable techniques, which are largely absent in other existing classification systems. These new techniques can be seen as further refinements of "problem-solving" or "coping planning." Due to data constraints stemming from the COVID-19 pandemic and the study's focus on a healthy Flemish student population, it is anticipated that more coping strategies would apply under normal conditions, in the general population, and among clinical groups. Future research should expand to diverse populations and establish connections between coping strategies and PA barriers, with ontologies recommended for this purpose. This study is a first step in classifying the content of coping strategies for PA. We believe this is an important and necessary step toward digital health interventions that incorporate personalized suggestions for PA coping plans.

Abstract
Pigs are widely used in metabolic research with procedures often requiring general anaesthesia. The aim was to investigate the effect of four different anaesthetic protocols: 1) isoflurane inhalation, 2) propofol infusion, 3) a mixture of tiletamine, zolazepam, medetomidine, ketamine and butorphanol (TZMKB)) and 4) ketamine combined with midazolam and xylazine (KMX)) on selected biomarkers during basal and glucose stimulated conditions. Eight domestic pigs were included in a cross-over design. Plasma concentrations of glucose, insulin, C-peptide, glucagon, cortisol, triglycerides, total cholesterol, aspartate amino transferase and alanine amino transferase, creatinine, urea, fructosamine, albumin, free fatty acids (FFAs) and glycerol were measured at baseline, during 2 h of anaesthesia and during 1 h of recovery. Intravenous glucose tolerance test (IVGTT, 0.5 g glucose/kg) was performed after 1 h of anaesthesia. Glucose disappearance rate and areas under the insulin, C-peptide and glucagon curves from the IVGTT were calculated. All four anaesthetic protocols affected glucose metabolism parameters significantly compared with un-anaesthetised pigs, which was particularly evident during IVGTT and for TZMKB and KMX anaesthesia. Propofol additionally influenced the plasma concentrations of triglycerides, FFAs and glycerol significantly. The remaining circulating biomarkers were largely unaffected by anaesthesia. These data underline the importance of considering the anaesthetic protocol in porcine studies of circulating metabolic biomarkers.

Abstract
Background and Objectives: This review paper highlights the key alternatives to the blue dye/radioisotope method of sentinel lymph node biopsy (SLNB). It analyses the research available on these alternative methods and their outcomes compared to the traditional techniques. Materials and Methods: This review focused on fifteen articles, of which five used indocyanine green (ICG) as a tracer, four used magnetic tracers, one used one-step nucleic acid amplification (OSNA) and Metasin (quantitative reverse transcriptase-polymerase chain reaction), one used the photosensitiser talaporfin sodium, one used sulphur hexafluoride gas microbubbles, one used CT-guided lymphography and two focused on general SLNB technique reviews. Results: Of the 15 papers analysed, the sentinel node detection rates were 69-100% for indocyanine green, 91.67-100% for magnetic tracers, 81% for talaporfin sodium, 9.3-55.2% for sulphur hexafluoride gas microbubbles, 90.5% for CTLG and 82.7-100% for one-step nucleic acid amplification. Conclusions: Indocyanine green fluorescence (ICG) and magnetic tracers have been proven non-inferior to traditional blue dye and isotope regarding SLNB localisation. Further studies are needed to investigate the use of these techniques in conjunction with each other and the possible use of language learning models. Dedicated studies are required to assess cost efficacy and longer-term outcomes.

Abstract
OBJECTIVE To compare the success rates for urethral catheterization in clinical patients using the traditional and 2-catheter techniques when placed by personnel of all experience levels. ANIMALS 38 female cats and dogs weighing less than 10 kg were prospectively enrolled. METHODS Enrolled animals were randomized to have a urethral catheter placed by the traditional technique or the 2-catheter method under sedation or general anesthesia. Any qualified hospital personnel of any experience level were allowed to place the catheter. If after 5 minutes the animal was not successfully catheterized, the alternate method was performed. The previous experience of the catheter placer, animal signalment, animal condition that necessitated catheter placement, time to successful placement, and which technique was successful was recorded. RESULTS The 2-catheter technique was more successful than the traditional method (60.5% and 34.2%, respectively) for urethral catheterization when used by a variety of hospital personnel. The 2-catheter technique was successful in 63.3% of dogs and 66.6% of cats, while the traditional method was successful in 36.6% of dogs and 33.3% of cats. Eight of 9 (88.9%) novice catheter placers that placed their first urinary catheter in this study succeeded with the 2-catheter technique and only 1 was successful with the traditional method. CLINICAL RELEVANCE The 2-catheter technique has a higher rate of success for placement of female urinary catheters in small patients that are unable to have concurrent digital palpation. This technique may also be helpful in the inexperienced catheter placer population to aid in guidance into the urethral papilla.

Abstract
Bacterial leaf streak, bacterial blight, and black chaff caused by Xanthomonas translucens pathovars are major diseases affecting small grains. Xanthomonas translucens pv. translucens and X. translucens pv. undulosa are seedborne pathogens that cause similar symptoms on barley, but only X. translucens pv. undulosa causes bacterial leaf streak of wheat. Recent outbreaks of X. translucens have been a concern for wheat and barley growers in the Northern Great Plains; however, there are limited diagnostic tools for pathovar differentiation. We developed a multiplex PCR based on whole-genome differences to distinguish X. translucens pv. translucens and X. translucens pv. undulosa. We validated the primers across different Xanthomonas and non-Xanthomonas strains. To our knowledge, this is the first multiplex PCR to distinguish X. translucens pv. translucens and X. translucens pv. undulosa. These molecular tools will support disease management strategies enabling detection and pathovar incidence analysis of X. translucens. [Formula: see text] Copyright © 2023 The Author(s).

Abstract
The endovascular intervention technique has gained prominence in the treatment of intracranial aneurysms due to its minimal invasiveness and shorter recovery time. A critical step of the intervention is the shaping of the microcatheter, which ensures its accurate placement and stability within the aneurysm sac. This is vital for enhancing coil placement and minimizing the risk of catheter kickback during the coiling process. Currently, microcatheter shaping is primarily reliant on the operator's experience, who shapes them based on the curvature of the target vessel and aneurysm location, utilizing 3D rotational angiography or CT angiography. Some researchers have documented their experiences with conventional shaping methods. Additionally, some scholars have explored auxiliary techniques such as 3D printing and computer simulations to facilitate microcatheter shaping. However, the shaping of microcatheters can still pose challenges, especially in cases with complex anatomical structures or very small aneurysms, and even experienced operators may encounter difficulties, and there has been a lack of a holistic summary of microcatheter shaping techniques in the literature. In this article, we present a review of the literature from 1994 to 2023 on microcatheter shaping techniques in endovascular aneurysm embolization. Our review aims to present a thorough overview of the various experiences and techniques shared by researchers over the last 3 decades, provides an analysis of shaping methods, and serves as an invaluable resource for both novice and experienced practitioners, highlighting the significance of understanding and mastering this technique for successful endovascular intervention in intracranial aneurysms.

Abstract
Postpartum neuropathies are common, including femoral neuropathy, peroneal neuropathy, lumbosacral trunk plexopathy, and lateral femoral cutaneous neuropathy. Sciatic mononeuropathy in the peripartum period is rare. Postpartum sciatic neuropathy (PSN) in the setting of cesarean section has been reported before. We present a case series of 2 sciatic mononeuropathies after vaginal delivery. Case 1 is a 25-year-old woman who presented with a left foot drop after normal vaginal delivery after being in labor for 3 hours. Case 2 is a 24-year-old woman who presented with a right foot drop after normal vaginal delivery and being in labor for 31 hours. Both cases noted foot drops in the immediate postpartum period. Neurologic examinations revealed flail foot, 4/5 hamstring muscle strength on MRC scale and intact hip abduction. They had paresthesia on the posterolateral aspect of the leg, dorsal and plantar aspect of the foot with absent ankle reflex. MRI did not show evidence of spinal cord, nerve root or plexus involvement. Electrodiagnostic studies revealed evidence of sciatic mononeuropathy proximal to the short head of biceps femoris. They were discharged home with an ankle brace and therapy. At 3 months follow up, they had complete resolution of weakness. There have been a few reported cases of PSN secondary to cesarean section. Sciatic involvement after vaginal delivery is extremely rare. We report 2 cases of PSN after vaginal delivery to highlight that sciatic mononeuropathy can occur not only after cesarean section, but also after uncomplicated vaginal delivery and should raise awareness of this risk to clinicians.

Abstract
The collagen antibody-induced arthritis (CAIA) model is highly effective in inducing arthritis, making it an attractive model for screening therapeutic compounds such as glucocorticoids (GCs). The severity of discomfort in this model makes it desirable to administer analgesics, but it is a prerequisite that these do not interfere with the model or tested therapeutics. In the present study, we studied the effect of 1 mg/mL tramadol and 3.5 mg/mL paracetamol (TP) on CAIA in male BALB/cAnNCrl mice and the possible interference of TP analgesia with the activity of the GC drug prednisolone (Pred). Our results showed that TP abolished the Pred-induced amelioration of CAIA, as well as several other Pred-induced effects, such as the reduction in thymus weight and the increase in insulin level. This most likely results from the effects of TP on the hepatic metabolism of this drug, since it strongly increased the Cyp3a11 expression in the liver. Altogether, we conclude that TP analgesia is not suitable for the CAIA model in male BALB/cAnNCrl mice, in particular when evaluating the effects of GCs such as Pred.

Abstract
The efficacy of currently available fungicides against apple scab, caused by the fungal pathogen Venturia inaequalis, was investigated in relation to when growers spray (ahead, during, or after rain) and how the spray reaches the target. The adaxial surface of individual leaves of potted trees were sprayed and then inoculated with ascospores of V. inaequalis, to establish dose-response curves for each fungicide. Discriminatory doses providing 50 and 90% symptom inhibition (EC50 and EC90, respectively) in sprays mimicking applications ahead of rain were used for experiments imitating alternative spray timings. Sprays were either applied during the spore germination phase or early or late after infection onset (either 336 or 672 degree-hours after inoculation, respectively), corresponding to grower spray schedules. Experiments were also carried out with sprays applied on the abaxial leaf surface to investigate fungicide efficacy through the leaf lamina. For all fungicides, the best efficacy was observed when sprays were applied during germination, followed by applications ahead of inoculation. Some products maintained equal or better efficacy at early infection, while efficacy in late infection dropped for all products, clearly indicating that this spray timing should be avoided. Some products with postinfection efficacy also showed translaminar efficacy. The close relationship found between EC50 of the active ingredients on potted trees and the label rate could help improve spraying decisions and reduce costs.

Abstract
BACKGROUND Modern technological advancements have led to increase in the development of surgical robots in dentistry, resulting in excellent clinical treatment outcomes. PURPOSE This study aimed to determine the accuracy of automatic robotic implant site preparation for different implant sizes by correlating planned and posttreatment positions, and to compare the performance of robotic and human freehand drilling. METHOD Seventy-six drilling sites on partially edentulous models were used, with three different implant sizes (Ø = 3.5 × 10 mm, 4.0 × 10 mm, 5.0 × 10 mm). The robotic procedure was performed using software for calibration and step-by-step drilling processes. After robotic drilling, deviations in the implant position from the planned position were determined. The angulation, depth, and coronal and apical diameters on the sagittal plane of sockets created by human and robotic drilling were measured. RESULTS The deviation of the robotic system was 3.78° ± 1.97° (angulation), 0.58 ± 0.36 mm (entry point), and 0.99 ± 0.56 mm (apical point). Comparison of implant groups showed the largest deviation from the planned position for 5 mm implants. On the sagittal plane, there were no significant differences between robotic and human surgery except for the 5-mm implant angulation, indicating similar quality between human and robotic drilling. Based on standard implant measurements, robotic drilling exhibited comparable performance to freehand human drilling. CONCLUSIONS A robotic surgical system can provide the greatest accuracy and reliability regarding the preoperative plan for small implant diameters. In addition, the accuracy of robotic drilling for anterior implant surgery can also be comparable to that of human drilling.

Abstract
Sealants may provide a solution for pulmonary air leakage (PAL), but their clinical application is debatable. For sealant comparison, standardized animal models are lacking. This systematic review aims to assess methodology and quality of animal models for PAL and sealant evaluation. All animal models investigating lung sealing devices (e.g., staplers, glues, energy devices) to prevent or treat PAL were retrieved systematically from Embase, Pubmed and Web of science. Methodological study characteristics, risk of bias, reporting quality and publication bias were assessed. A total of 71 studies were included (N = 75 experiments, N = 1659 animals). Six different species and 18 strains were described; 92% of experiments used healthy animals, disease models were used in only six studies. Lesions to produce PAL were heterogenous, and only 11 studies used a previously reported technique, encompassing N = 5 unique lesions. Clinically relevant outcomes were used in the minority of studies (imaging 16%, air leak 10.7%, air leak duration 4%). Reporting quality was poor, but revealed an upward trend per decade. Overall, high risk of bias was present, and only 18.7% used a negative control group. All but one study without control groups claimed positive outcomes (95.8%), in contrast to 84.3% using positive or negative control groups, which also concluded equivocal, adverse or inconclusive outcomes. In conclusion, animal studies evaluating sealants for prevention of PAL are heterogenous and of poor reporting quality. Using negative control groups, disease models and quantifiable outcomes seem important to increase validity and relevance. Further research is needed to reach consensus for model development and standardization.

Abstract
Employing the in-plane technique in infants the footprint of the ultrasound probe should be considered along with the depth of the vein, and the angle between the needle and the face of the probe, which is crucial in optimization of the visibility of the needle in the beam. Three different ultrasound probes are evaluated for different depths of vein. The hockey-stick probe provided a shorter minimum distance while maintaining the angle between the needle and the face of the probe within an optimal range for visualization of the needle in the beam, supporting its recommendation for infants with regard to its frequency and physical size.

Abstract
The use of animals to gain knowledge and understanding of diseases needs to be reduced and refined. In the field of intestinal research, because of the complexity of the gut immune system, living models testing is mandatory. Based on the 3Rs (replacement, reduction and refinement) principles, we aimed to developed and apply the derived-intestinal surgical procedure described by Bishop and Koop (BK) in rats to refine experimental gastrointestinal procedures and reduce the number of animals used for research employing two models of intestinal inflammation: intestinal ischemia-reperfusion injury and chemical-induced colitis. Our results show the feasibility of the application of the BK technique in rodents, with good success after surgical procedure in both small and large intestine (100% survival, clinical recovery and weight regain). A considerable reduction in the use of the number of rats in both intestinal inflammation models (80% in case of intestinal ischemia-reperfusion damage and 66.6% in chemical-induced colitis in our experimental design) was achieved. Compared with conventional experimental models described by various research groups, we report excellent reproducibility of intestinal damage and functionality, survival rate and clinical status of the animals when BK is applied.

Abstract
Information about the diploid genotype of a gene-modified or mutant laboratory animal is essential for breeding and experimental planning. It is also required for the exchange of animals between different research groups or for communication with professional genotyping service providers. While there are detailed, standardized rules for creating an allele name of a genome modification or mutation, the notation of the diploid genotype after biopsy and genotyping has not been standardized yet. Therefore, a uniform, generally understandable nomenclature for the diploid genotype of gene-modified laboratory animals is needed. With the here-proposed nomenclature recommendations from the Committee on Genetics and Breeding of Laboratory Animals of the German Society for Laboratory Animal Science (GV-SOLAS), we provide a practical, standardized representation of the genotype of gene-modified animals. It is intended to serve as a compact guide for animal care and scientific personnel in animal research facilities and to simplify data exchange between groups and with external service providers.

Abstract
Age-related macular degeneration (AMD) is a complex and multifactorial disease characterized by the damage of the unit comprised of the photoreceptors, retinal pigment epithelium (RPE), Bruch's membrane, and choriocapillaris. Although the outer retina appears to be mainly affected in this disorder, several evidences exhibit that also the inner retina may be impaired. In this review we will provide a description of the prominent histologic and imaging findings suggesting an inner retinal loss in these eyes. In details, structural optical coherence tomography (OCT) technology proved either the inner and outer retina is impacted by AMD and that these two impairments are associated. Therefore, the purpose of this review is to provide a description of the role of neurodegeneration in AMD in order to better understand the relationship between neuronal loss and the outer retinal damage in this disease.

Abstract
SUMMARY Sports-related concussion is now in public awareness more than ever before. Investigations into underlying pathophysiology and methods of assessment have correspondingly increased at an exponential rate. In this review, we aim to highlight some of the evidence supporting emerging techniques in the fields of neurophysiology, neuroimaging, vestibular, oculomotor, autonomics, head sensor, and accelerometer technology in the setting of the current standard: clinical diagnosis and management. In summary, the evidence we reviewed suggests that (1) head impact sensors and accelerometers may detect possible concussions that would not otherwise receive evaluation; (2) clinical diagnosis may be aided by sideline vestibular, oculomotor, and portable EEG techniques; (3) clinical decisions on return-to-play eligibility are currently not sensitive at capturing the neurometabolic, cerebrovascular, neurophysiologic, and microstructural changes that biomarkers have consistently detected days and weeks after clinical clearance. Such biomarkers include heart rate variability, quantitative electroencephalography, as well as functional, metabolic, and microstructural neuroimaging. The current challenge is overcoming the lack of consistency and replicability of any one particular technique to reach consensus.

Abstract
Open research practices have been highlighted extensively during the last 10 years in many fields of scientific study as essential standards needed to promote transparency and reproducibility of scientific results. Scientific claims can only be evaluated based on how protocols, materials, equipment, and methods were described; data were collected and prepared; and analyses were conducted. Openly sharing protocols, data, and computational code is central to current scholarly dissemination and communication, but in many fields, including plant pathology, adoption of these practices has been slow. We randomly selected 450 articles published from 2012 to 2021 across 21 journals representative of the plant pathology discipline and assigned them scores reflecting their openness and computational reproducibility. We found that most of the articles did not follow protocols for open science and failed to share data or code in a reproducible way. We propose that use of open-source tools facilitates computationally reproducible work and analyses, benefitting not just readers but the authors as well. Finally, we provide ideas and suggest tools to promote open, reproducible computational research practices among plant pathologists. [Formula: see text] Copyright © 2023 The Author(s).

Abstract
Head and neck cancer (HNC) is one of the most common cancers on the planet, with approximately 600,000 new cases diagnosed and 300,000 deaths every year. Research into the biological basis of HNC has advanced slowly over the past decades, which has made it difficult to develop new, more effective treatments. The patient-derived organoids (PDOs) are made from patient tumor cells, resembling the features of their tumors, which are high-fidelity models for studying cancer biology and designing new precision medicine therapies. In recent years, considerable effort has been focused on improving "organoids" technologies and identifying tumor-specific medicine using head and neck samples and a variety of organoids. A review of improved techniques and conclusions reported in publications describing the application of these techniques to HNC organoids is presented here. Additionally, we discuss the potential application of organoids in head and neck cancer research as well as the limitations associated with these models. As a result of the integration of organoid models into future precision medicine research and therapeutic profiling programs, the use of organoids will be extremely significant in the future.

Abstract
Background Studies to date comparing biceps tenodesis methods in the setting of concomitant rotator cuff repair (RCR) have demonstrated relatively equivalent pain and functional outcomes. Purpose To compare biceps tenodesis constructs, locations, and techniques in patients who underwent RCR using a large multicenter database. Study Design Cohort study; Level of evidence, 3. Methods A global outcome database was queried for patients with medium- and large-sized tears who underwent biceps tenodesis with RCR between 2015 and 2021. Patients ≥18 years of age with a minimum follow-up of 1 year were included. The American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) scores were compared at 1 and 2 years of follow-up based on construct (anchor, screw, or suture), location (subpectoral, suprapectoral, or top of groove), and technique (inlay or onlay). Nonparametric hypothesis testing was used to compare continuous outcomes at each time point. The proportion of patients achieving the minimal clinically important difference (MCID) at the 1- and 2-year follow-ups were compared between groups using chi-square tests. Results A total of 1903 unique shoulder entries were analyzed. Improvement in VR-12 Mental score favored anchor and suture fixations at 1 year of follow-up (P = .042) and the onlay tenodesis technique at 2 years of follow-up (P = .029). No additional tenodesis comparisons demonstrated statistical significance. The proportion of patients with improvement exceeding the MCID did not differ based on tenodesis methods for any outcome score assessed at the 1- or 2-year follow-up. Conclusion Biceps tenodesis with concomitant RCR led to improved outcomes regardless of tenodesis fixation construct, location, or technique. A clear optimal tenodesis method with RCR remains to be determined. Surgeon preference and experience with various tenodesis methods as well as patient clinical presentation should continue to guide surgical decision-making.

Abstract
As a neurodegenerative disease, Alzheimer's disease (AD) is characterized by synaptic loss, extracellular plaques of amyloid accumulation, hyperphosphorylation of tau, and neuroinflammation. Various biological processes are affected by epitranscriptomic modifications, which regulate the metabolism of mRNA in cells and regulate the expression of genes. In response to changes in m6A modification levels, the nervous system becomes dysfunctional and plays a significant role in the development of Alzheimer's disease. As a result of recent research, this paper reviews advances in the understanding of the regulatory mechanisms of m6A modification in the occurrence and development of AD. In addition, the article discusses recent research techniques related to animal models of m6A and AD. Furthermore, it discusses the possibility of studying the pathogenesis of AD at the level of the epitranscriptome, identifying early diagnostic markers, and screening for effective treatment options.

Abstract
Background Optimal infant feeding is critical for children's growth and development during their first years of life. Plenty of evidence on ineffective breastfeeding techniques, yet the problem is still deep-rooted and requires further research in Ethiopia. Objective To determine the proportion of ineffective breastfeeding techniques and associated factors among breastfeeding mothers who gave birth in the last 6 months in Sinan Woreda. Design and methods A community-based cross-sectional study was conducted from March 10 to April 8, 2021 with a total of 389 samples. A computer-generated simple random sampling was used to select mothers. An observational checklist and interviewer-administered questionnaires were used. EpiData 4.2 for data entry and SPSS 25 for cleaning and analysis were used. Variables with a p-value < 0.05 and 95% confidence interval (CI) corresponding adjusted odds ratio (AOR) were used to identify factors of ineffective breastfeeding techniques. Results The proportion of ineffective breastfeeding techniques was 66.8%. The mean (SD) age of mothers was 29.4 ± 5.95 years. No formal education [AOR: 5.88 (95% CI: (2.97, 11.65)], primipara [AOR: 4.34 (95% CI: 2.25, 8.36)], home delivery [AOR: 3.02 (95% CI: 1.12, 8.14)], not received breastfeeding counseling during antenatal care [AOR: 4.94 (95% CI: 1.83, 13.36)], breast problem [AOR: 2.62 (95% CI: 1.25, 5.48)], and breastfeeding experience [AOR: 1.82 (95% CI: 1.01, 3.28)] were statistically significant factors. Conclusions The proportion of ineffective breastfeeding techniques 66.8% was unacceptable. Socio-demographic and maternal health care services were identified factors. Strengthening maternal care, improving health education and promotions, and designing appropriate strategies were required.

Abstract
BACKGROUND Intrathecal nusinersen administration, a fundamental step in the treatment of spinal muscular atrophy, is challenging in children. AIMS This retrospective monocentric analysis of prospectively collected data evaluated the feasibility of needleless general anesthesia exclusively with sevoflurane, without imaging guidance, for children undergoing nusinersen administration in a 24-month period. METHODS Clinical data included demographics, type of spinal muscular atrophy, presence and severity of scoliosis. Primary outcome was defined by the number of predefined sentinel adverse events related to anesthesia. Secondary outcomes were assessed by duration of the procedure, number of lumbar puncture attempts, and number of failures. Other measures included number and type of moderate, minor and minimal adverse events, as well as number and type of puncture-related adverse events. RESULTS 116 patients (mean age: 8.7 (SD 6.9) years; with scoliosis: 49.1%) underwent 250 lumbar punctures; two cases of prolonged desaturation, considered as sentinel adverse events, (0.8%) were recorded during anesthesia (primary outcome). None of the patients underwent orotracheal intubation nor required an unplanned admission in the Pediatric Intensive Care Unit. No patient required an unplanned or prolonged hospitalization after the procedure. Mean number of puncture attempts was 1.6 (SD 1.3), and mean duration of the procedure was 14.1 (SD 8.3) minutes. No failure in the drug administration occurred (secondary outcomes). CONCLUSION In this single-center experience, needleless general anesthesia with inhaled sevoflurane without imaging guidance has been shown to be feasible for children with spinal muscular atrophy undergoing lumbar puncture for nusinersen administration.

Abstract
Cephalosporium gramineum survives primarily in colonized plant residue but is also transmitted by seed at a low frequency. The purpose of this study was to correlate disease intensity in the field with percentage of infected seed and amount of pathogen DNA using a high-throughput PCR method. Field-grown seed of three wheat cultivars was collected over 4 years from plots with a known disease index. The culture-based seed infection rate was determined by isolation of C. gramineum from 2,016 seeds per seed lot. DNA of 380 seeds from each seed lot was extracted individually, and a PCR assay with a fluorescent-labeled forward primer for detecting C. gramineum was performed on each seed. C. gramineum was isolated from 0.12% of the seed on average (range 0 to 0.74%), whereas it was detected in 3.7% on average (range 1.3 to 7.6%) using PCR detection. The single-seed PCR assay was more sensitive than either the culture-based method or conventional PCR. DNA of 674 seeds that tested positive by this PCR was quantified using a real-time PCR with newly designed primers for the amount of pathogen per seed. Seed contained 0.017 to 77.1 pg/seed of C. gramineum DNA (mean 3.0 pg/seed). Disease index was positively correlated with seed infection rate but not with pathogen titer in seed. This fluorescent-labeled PCR, along with quantitative PCR, improved our understanding of seed transmission of C. gramineum in wheat.

Abstract
Springboard diving training is often focused upon skill repetition to establish movement accuracy, stability and consistency. Within-participant study designs provide the ability to understand how individuals create these skills under different movement strategies. IMUs measured angular velocity time-series data of two athletes performing multiple repetitions of forward 3½ somersault pike dives. Functional Principal Component Analyses (fPCA) were performed to examine individual movement structure and variability. The first five fPC's represented approximately 98% of the variability in angular velocity for both divers. To determine the relative importance of angular velocity variability, Pearson's correlations for pairwise comparisons were used to assess the relationship between fPC scores and discrete performance variables during takeoff, flight and entry. Divers exhibited a different number and types of significant correlations (International = 4; National = 11). Only one correlation was common for both divers; higher angular velocity during Initial Flight and/or Somersault phases resulted in more vertically aligned entry posture (International: fPC1 r = -0.761, p < 0.05; National: fPC3 r = -0.796, p < 0.01). Findings identify individualised angular velocity time-series structure and kinematic performance variables (International = angular; National = linear) that can be used by coaching/sport science teams to optimisation performance success.

Abstract
Since time immemorial, human beings have sought natural medications for treatment of various diseases. Weighty evidence demonstrates the use of chemical methodologies for sensitive evaluation of cytotoxic potentials of herbal agents. However, due to the ubiquitous use of cytotoxicity methods, there is a need for providing updated guidance for the design and development of in vitro assessment. The aim of this review is to provide practical guidance on common cell-based assays for suitable assessment of cytotoxicity potential of herbal medicines and discussing their advantages and disadvantages Relevant articles in authentic databases, including PubMed, Web of Science, Science Direct, Scopus, Google Scholar and SID, from 1950 to 2022 were collected according to selection criteria of in vitro cytotoxicity assays and protocols. In addition, the link between cytotoxicity assay selection and different factors such as the drug solvent, concentration and exposure duration were discussed.
