Abstract
OBJECTIVES To investigate cleft laterality dental arch relationship outcomes of children with non-syndromic complete unilateral cleft lip and palate (UCLP) in New Zealand. DESIGN A retrospective nationwide study. SETTINGS Virtual 3D orthodontic study models collected prior to undertaking secondary alveolar bone grafting. PARTICIPANTS A total of 104 patients with UCLP (L = 80: R = 24). OUTCOME MEASURES Four calibrated assessors used the GOSLON Yardstick and 100 mm Visual Analogue Scale (VAS) to score the randomised models on 2 separate assessment sessions. Weighted Kappa were used to determine the intra/inter-rater reliability for the GOSLON and correlations for the VAS. RESULTS Intra-rater reliability ranged from 0.57-0.88 (GOSLON) and 0.45-0.93 (VAS). Inter-rater reliability ranged from 0.62-0.86 (GOSLON) and 0.64-0.93 (VAS).GOSLON scores for the left UCLP were 31.2% for good/very good; 26.3% for fair; 42.5% for poor/very poor while the right UCLP scored 8.3% for good/very good; 37.5% for fair; 54.2% for poor/very poor. The mean VAS for left and right UCLP were 53.4 (sd 22.5) and 44.6 (sd 17.1) respectively. Neither the GOSLON nor VAS differences reached statistical significance (both P = .08). CONCLUSIONS From a clinical perspective right UCLP had worse dental arch relationship outcomes, however, these differences failed to reach statistical significance. Further studies using larger sample sizes are required to determine if cleft laterality is an important consideration when investigating UCLP dental arch outcomes.

Abstract
OBJECTIVE Inflammation has a vital role in tumor development and metastasis. Changes in blood count parameters have been associated with tumor prognosis. We aimed to evaluate the prognostic significance of neutrophil to lymphocyte ratio (NLR) in predicting lung metastasis of giant cell tumors of the bone (GCTB) of the extremities. PATIENTS AND METHODS 34 GCTB patients (22 males and 12 females) were included in the study. Patients were divided into two groups. The metastasis group (n = 7) included GCTB patients with lung metastasis, while the non-metastasis group (n = 27) included those without lung metastasis. Descriptive statistics and frequency distribution were calculated [age, white blood cell (WBC), neutrophil, lymphocyte, platelets, neutrophil to lymphocyte ratio (NLR), and platelets to lymphocytes ratio (PLR)]. Continuous normal variables were expressed as mean ± standard deviation and compared using Student's t-tests. The receiver operating characteristic (ROC) curve analysis was used to evaluate the ability of NLR and PLR to predict lung metastasis. The factors were considered to be statistically significant at p < 0.05. RESULTS There were no significant differences between the lymphocyte count (1.81 vs. 2.23 103/mm3), platelet count (436 vs. 364 103/mm3), and PLR values (247 vs. 190) of the two groups (p > 0.05). The WBC count (11.8 vs. 8.95 103/mm3), neutrophil count (8.78 vs. 5.69 103/mm3), and NLR levels (5.45 vs. 2.81) (p < 0.05) were significantly higher in the metastasis group. The presence of an NLR cut-off value of 3.7 significantly predicted the existence of lung metastasis (AUC = 0.857 [95%CI = 0.714-1], p = 0.004) with a sensitivity of 85% and specificity of 82%. CONCLUSIONS NLR may serve as a promising prognostic marker for predicting lung metastasis in GCTB patients.

Abstract
Abstract
Background
To report our recommended methodology for extracting and then confirming research uncertainties – areas where research has failed to answer a research question – derived from previously published literature during a broad scope Priority Setting Partnership (PSP) with the James Lind Alliance (JLA).
Methods
This process was completed in the UK as part of the PSP for “Common Conditions Affecting the Hand and Wrist”, comprising of health professionals, patients and carers and reports the data (uncertainty) extraction phase of this. The PSP followed the robust methodology dictated by the JLA and sought to identify knowledge gaps, termed “uncertainties” by the JLA. Published Cochrane Systematic Reviews, Guidelines and Protocols, NICE (National Institute for Health and Care Excellence) Guidelines, and SIGN (Scottish Intercollegiate Guidelines Network) Guidelines were screened for documented “uncertainties”. A robust method of screening, internally verifying and then checking uncertainties was adopted. This included independent screening and data extraction by multiple researchers and use of a PRISMA flowchart, alongside steering group consensus processes.
Selection of research uncertainties was guided by the scope of the Common Conditions Affecting the Hand and Wrist PSP which focused on “common” hand conditions routinely treated by hand specialists, including hand surgeons and hand therapists limited to identifying questions concerning the results of intervention, and not the basic science or epidemiology behind disease.
Results
Of the 2358 records identified (after removal of duplicates) which entered the screening process, 186 records were presented to the PSP steering group for eligibility assessment; 79 were deemed within scope and included for the purpose of research uncertainty extraction (45 full Cochrane Reviews, 18 Cochrane Review protocols, 16 Guidelines). These yielded 89 research uncertainties, which were compared to the stakeholder survey, and added to the longlist where necessary; before derived uncertainties were checked against non-Cochrane published systematic reviews.
Conclusions
In carrying out this work, beyond reporting on output of the Common Conditions Affecting the Hand and Wrist PSP, we detail the methodology and processes we hope can inform and facilitate the work of future PSPs and other evidence reviews, especially those with a broader scope beyond a single disease or condition.

Abstract
Abstract
Background
The RAFAU is a Multidisciplinary Team including Medical, Physiotherapy and Occupational Therapy, incorporating a fulltime team of OT and PT based in the Emergency Department called RAFT (Rapid Access Frailty Team). It aims to prevent hospital admissions and social crises. There are three main referral pathways, via community (GP, Public Health Nurses, Allied Health Professionals), RAFT-ED, and general medical follow up.
Methods
The data used was from RAFAU attendances between May 2021 and March 2022. Inclusion criteria was age greater than 65 and attendance in person. Exclusion criteria was incomplete data. Data was manually recorded after each attendance using data entry points including age range, methods of and reason for referral, etc. This gave us the raw data to develop information on our cohort. Data analysis was completed using Excel.
Results
A total of 569 patients were seen. The most populous age brackets were 81-85 (28%), 70-75 (25%) and 75-80 (26%) respectively. The vast majority of referrals were from GPs (57%), followed by RAFT-ED (30%). The most common reasons for referral were Medical (34%), Cognitive (27%) and Falls (26%).
Conclusion
A significant number of patients were seen for the first time by the RAFAU MDT. GPs were the major source of referrals which is to be expected as GPs are in more frequent contact with patients and act as gatekeepers to specialist hospital services. The primary referral reasons were also to be expected as these are three issues that are at the core of Gerontology. 173 hospital admissions were prevented in the ED by a combination of the RAFT and Emergency Doctors. There is good rationale for keeping the RAFAU and RAFT-ED team, and where possible expanding their services. This model could easily be expanded to other hospitals.

Abstract
Hip extensor muscles are critical to sport performance as events requiring sprinting and forceful landings are highly dependent on these muscles. Despite biomechanical differences between the barbell hip thrust (BHT) and the barbell glute bridge (BGB), both are biomechanically efficient ways to load this musculature for training purposes. Research investigating the differences in muscular activity between the BHT and BGB has yet been conducted. The aim of this study was to investigate, through surface electromyography, if one exercise is more optimal than the other in producing greater muscle activation for specific hip extensor muscles. Ten male participants completed a two-part study protocol. Results revealed the BHT elicited significantly greater muscle activity within the vastus lateralis for peak and mean outcomes; however, the BGB elicited significantly greater muscle activity in the upper and lower gluteus maximus for peak and mean outcomes and mean outcome in the gluteus medius. Current findings suggest, the BGB is, at minimum, a superior substitute for the BHT for eliciting a larger magnitude of activity in the gluteus maximus. Future studies between the two exercises are warranted to discern which produces greater hypertrophy and whether adaption of the BHT or BGB transfers more optimally to sport performance.

Abstract
Objective: The microanatomy of the fronto-ethmoidal transition region has been addressed in several classifications. CT stereoscopic imaging (3DCTSI) provides improved display and delineates three defined complex “spaces”, the Frontal Sinus/Frontal Recess Space, the Infundibular Space of the Ethmoid Uncinate Process, and the Ethmoid Bulla Space (FSRS, IS-EUP, EB), none of which were adequately described with the “cell” terminology. We present details on the 3D microanatomy, variability, and prevalence of these spaces. Methods: 3D stereoscopic imaging displays (3DCTSI) were created from 200 datasets. The images were analyzed and categorized by a radiologist (SJZ), and consultant otolaryngologists, focusing on 3D microanatomy of the fronto-ethmoidal transition, the frontal recess/frontal sinus, and drainage pathways, in comparison to established anatomical classification systems. Results: The anterior ethmoid is subdivided into seven groups with the following core properties and prevalence: 1. The horizontal roof of the IS-EUP is attached to the superior half of the frontal process of the maxilla (19%); 2. The IS-EUP extends into the frontal recess (6.5%); 3. The IS-EUP extends into the frontal recess and the frontal sinus (18.5%); 4. A bulla is seen in the medial frontal sinus (3%); 5. The ethmoid bulla and supra bullar space extend into the frontal sinus (7%); 6. Lamellae extend into the FSRS antero-superiorly (25%); 7. FSRS expansion expands below the upper half of the frontal process of the maxilla (FSRS) (21%). Conclusion: 3-D analysis of the detailed anatomy provides important new anatomic information with the increased focus on precision surgery in the region.

Abstract
OBJECTIVE: The objective of this presentation is to display a series of new anatomical concepts and terms regarding the frontal si- nus, its drainage pathway and cells vs. spaces of the anterior ethmoid, based on Three-Dimensional Computer X-ray Tomography Stereoscopic Imaging (3DCTSI) and contrast these concepts to those reported in the current literature. METHODS: Given the new anatomic observations provided by 3DCTSI, and the widespread anatomic variations a small sample was initially selected to describe our observations. Six exemplary cases according to the “Classification of Fronto-Ethmoidal cells” by Kuhn, Bent et al., Lee et al., expanded by Wormald et al., and adopted by Ramakrishnan et al., Huang et al., and Void et al. (1-7) were chosen to illustrate our detailed anatomic observations. Additional observations and data of prevalence identified in a larger series will follow. RESULTS and CONCLUSION: Conceptually, the anterior ethmoid “cells” are in essence “spaces” with openings that communicate with the middle meatus and/or the ethmoidal infundibulum. The frontal sinus and frontal recess are a united and continuous three-dimensional, irregularly shaped space, the Frontal Sinus/Recess Space (FSRS). The uncinate process has two segments: the Ethmoidal Uncinate Process (EUP), which encompasses the Infundibular Space of the EUP (IS-EUP), currently known as the Agger Nasi cell; and the Turbinal Uncinate Process (TUP), which borders the Turbinal Infundibulum (TI) medially. The superior attach- ment of the EUP will be detailed in each of the six cases (Table 2). The middle meatus and infundibular passages are the drainage pathways from the frontal sinus and maxillary sinus to the nasal cavity.

Abstract
The Linac coherent light source x-ray free-electron laser is a complex scientific apparatus which changes configurations multiple times per day, necessitating fast tuning strategies to reduce setup time for successive experiments. To this end, we employ a Bayesian approach to maximizing x-ray laser pulse energy by controlling groups of quadrupole magnets. A Gaussian process model provides probabilistic predictions for the machine response with respect to control parameters, enabling a balance of exploration and exploitation in the search for the global optimum. We show that the model parameters can be learned from archived scans, and correlations between devices can be extracted from the beam transport. The result is a sample-efficient optimization routine, combining both historical data and knowledge of accelerator physics to significantly outperform existing optimizers.

Abstract
Abstract
A collaborative study was conducted for the capillary gas chromatographic (GC) method for the simultaneous determination of the fungicide chlorothalonil (CTL) and the accompanying impurity, hexachlorobenzene (HCB), in technical and formulated materials. The method calls for the dissolution of technical and dry formulations of CTL and HCB from the aqueous flowable formulation. The 10 participating laboratories were asked to analyze the samples by adhering to the method as closely as their instrumentation and data systems allowed, and to note any deviations from the method. Collaborators were asked to prepare the standards and samples, set up the capillary GC systems, analyze the samples, and calculate the results. CTL produced reproducibility relative standard deviations (RSDR) of 0.4–2.5 (active ingredient concentrations ranged from approximately 52 to 98% by weight). HCB produced RSDR values of 5.2–22% (HCB concentrations were 0.02–0.04% by weight). The method was adopted First Action by AOAC INTERNATIONAL.

Abstract
In vitro fertilization has served as a great tool in the human and bovine field in its ability to treat infertility in females. The purpose of this study was to compare hormone injection treatments in goats using the laparoscopic ovum pickup technique. A crossover trial was conducted to evaluate 2 superovulation injection protocols [a multiple-injection FSH (F) and a one-injection FSH-eCG (F+E)] for their ability to increase recovery of oocytes using laparoscopic ovum pickup (LOPU) technique in 10 prepubertal Kiko does. Does were randomly assigned to 2 sequence groups (n=5). Period 1 initiated on 28 July 2017 and Period 2 on 12 August 2017. A CIDR device was inserted on Day 0 and removed after LOPU. On Day 6 of each period, 3mL of prostaglandin F2α was given IM to each doe. F-treated does received (IM) twice daily injections of 15, 12.5, 10, and 7.5mg of FSH, whereas F+E-treated does received (IM) 80mg of FSH and 300 international units (IU) of eCG. Thirty-six hours after injection, follicles were aspirated using LOPU. Treatment response measurements included total follicles observed, oocyte recovery rate, and blastocyst rate. Total follicles observed were higher (P=0.004) in F+E-treated does (305 follicles) than F-treated does (236 follicles). Neither oocyte recovery rates (F+E=41.5% and F=38.1%) nor blastocysts rates (F+E=18% and F=32%) were affected (P>0.05) by injection protocol. In conclusion, we summarise that multiple injections of FSH can results in a higher number of follicles produced; however, this does not have a subsequent effect on IVF and development rates.

Abstract
Background Randomized controlled trials of prenatal omega (ω-3) long chain polyunsaturated fatty acid (LCPUFA) supplementation are suggestive of some protective effects on allergic sensitization and symptoms of allergic disease in childhood. Due to the nature of the atopic march, investigation of any effects of this prenatal intervention may be most informative when consistently assessed longitudinally during childhood. Methods Follow-up of children (n = 706) with familial risk of allergy from the Docosahexaenoic Acid to Optimize Mother Infant Outcome (DOMInO) trial. The intervention group received fish oil capsules (900 mg of ω-3 LCPUFA) daily from <21 weeks' gestation until birth; the control group received vegetable oil capsules without ω-3 LCPUFA. This new longitudinal analysis reports previously unpublished data collected at 1 and 3 years of age. The allergic disease symptom data at 1, 3 and 6 years of age were consistently reported by parents using the "International Study of Asthma and Allergies in Childhood" (ISAAC) questionnaire. Sensitization was determined by skin prick test to age specific, common allergen extracts. Results Changes over time in symptoms of allergic disease with sensitization (IgE-mediated) and sensitization did not differ between the groups; interaction p = 0.49, p = 0.10, respectively. Averaged across the 1, 3 and 6-year assessments, there were no significant effects of prenatal ω-3 LCPUFA supplementation on IgE-mediated allergic disease symptoms (adjusted relative risk 0.88 (95% CI 0.69, 1.12), p = 0.29) or sensitization (adjusted relative risk 0.97 (95% CI 0.82, 1.15), p = 0.76). Sensitization patterns to common allergens were consistent with the atopic march, with egg sensitization at 1 year strongly associated with house dust mite sensitization at 6 years, (p < 0.0001). Discussion Although there is some evidence to suggest that maternal supplementation with 900mg ω-3 LCPUFA has a protective effect on early symptoms of allergic disease and sensitization in the offspring, we did not observe any differences in the progression of disease over time in this longitudinal analysis. Further investigation into the dose and timing of ω-3 LCPUFA supplementation, including long-term follow up of children using consistent outcome reporting, is essential to determine whether this intervention may be of benefit as a primary prevention strategy for allergic disease. Conclusion Maternal supplementation with 900 mg of ω-3 LCPUFA did not change the progression of IgE-mediated allergic disease symptoms or sensitization throughout childhood from 1 to 6 years.

Abstract
OBJECTIVE Adapt and evaluate the feasibility of implementing Good Life with osteoArthritis in Denmark (GLA:DTM) in Canada for people with mild to severe hip/knee osteoarthritis. METHODS Patients triaged to non-surgical management participated in two education sessions and 12 supervised, neuromuscular exercise classes. We used the RE-AIM implementation framework evaluating outcomes of Reach, Effectiveness/Efficacy, Adoption, Implementation and Maintenance. Patients completed surveys pre-program and at 3 months follow-up. Program fidelity was evaluated at four observations against a priori criteria. We conducted semi-structured interviews with therapists post-program. RESULTS 72 patients consented to participate, 59 started the program and one withdrew on physician advice. The remaining 58 provided follow-up data. Mean age was 67 years; 78% were female and 52% had body mass index (BMI) >25. The effect of the program was demonstrated: 40% improvement in pain with 59% achieving a clinically important improvement of ≥2 points on the Numeric Pain Rating scale. Statistically significant improvement also occurred in the Hip disability/Knee injury and Osteoarthritis Outcome Score subscales. 24% reported increased physical activity. Program fidelity was demonstrated with all criteria met. Therapists emphasized that rolling recruitment allowed appropriate supervision and resulted in participants encouraging each other. 99% of participants indicated they benefitted from and were satisfied with the program and 90% reported using the knowledge daily. 52% were willing to pay >$250 Cdn for the program. CONCLUSION GLA:DTM implementation was feasible in the Canadian context with results similar to those of >7,000 participants in Denmark. Implementation and evaluation of GLA:DTM Canada is now occurring nationally.
