Abstract
BACKGROUND Exposure to mental health problems are becoming increasingly more frequent within physiotherapy. Physiotherapists recognize the need for a biopsychosocial approach, however their knowledge, assessment, and treatment skills specific to mental health problems requires further research. PURPOSE To profile the level of education and perception of education that physiotherapists have acquired specific to mental health problems; and to profile an understanding of the current practice of physiotherapists specific to mental health problems. METHODS An online survey addressed the aims of the study and collected data from physiotherapists in Australia and New Zealand (open between 20th of October 2022 to the 20th of March 2023). RESULTS 139 respondents were included in the analysis. Physiotherapists had a perception that a significantly greater amount of coursework related to mental health needed to be included within their initial degree compared to what they received (mean difference of 20.0%, 95% CI: 17.5 to 22.5). This trend was evident irrespective of the degree level or the year of graduation. Higher perceived knowledge of anxiety (MD of 11.4, p = 0.001, ES: 0.5) and depression (MD of 11.8, p = 0.001, ES: 0.5) was evident in outpatient care physiotherapists. Lack of perceived knowledge is a reason for whether an assessment or treatment strategy is used with patients experiencing a mental health problem. Motivational interviewing and mindfulness were the most frequently used psychologically based techniques. CONCLUSION This study reveals the need to increase the amount of mental health and psychologically based techniques within Physiotherapy curriculum.

Abstract
BACKGROUND AND OBJECTIVES In Parkinson disease (PD), Alzheimer disease (AD) copathology is common and clinically relevant. However, the longitudinal progression of AD CSF biomarkers-β-amyloid 1-42 (Aβ42), phosphorylated tau 181 (p-tau181), and total tau (t-tau)-in PD is poorly understood and may be distinct from clinical AD. Moreover, it is unclear whether CSF p-tau181 and serum neurofilament light (NfL) have added prognostic utility in PD, when combined with CSF Aβ42. First, we describe longitudinal trajectories of biofluid markers in PD. Second, we modified the AD β-amyloid/tau/neurodegeneration (ATN) framework for application in PD (ATNPD) using CSF Aβ42 (A), p-tau181 (T), and serum NfL (N) and tested ATNPD prediction of longitudinal cognitive decline in PD. METHODS Participants were selected from the Parkinson's Progression Markers Initiative cohort, clinically diagnosed with sporadic PD or as controls, and followed up annually for 5 years. Linear mixed-effects models (LMEMs) tested the interaction of diagnosis with longitudinal trajectories of analytes (log transformed, false discovery rate [FDR] corrected). In patients with PD, LMEMs tested how baseline ATNPD status (AD [A+T+N±] vs not) predicted clinical outcomes, including Montreal Cognitive Assessment (MoCA; rank transformed, FDR corrected). RESULTS Participants were 364 patients with PD and 168 controls, with comparable baseline mean (±SD) age (patients with PD = 62 ± 10 years; controls = 61 ± 11 years]; Mann-Whitney Wilcoxon: p = 0.4) and sex distribution (patients with PD = 231 male individuals [63%]; controls = 107 male individuals [64%]; χ2: p = 1). Patients with PD had overall lower CSF p-tau181 (β = -0.16, 95% CI -0.23 to -0.092, p = 2.2e-05) and t-tau than controls (β = -0.13, 95% CI -0.19 to -0.065, p = 4e-04), but not Aβ42 (p = 0.061) or NfL (p = 0.32). Over time, patients with PD had greater increases in serum NfL than controls (β = 0.035, 95% CI 0.022 to 0.048, p = 9.8e-07); slopes of patients with PD did not differ from those of controls for CSF Aβ42 (p = 0.18), p-tau181 (p = 1), or t-tau (p = 0.96). Using ATNPD, PD classified as A+T+N± (n = 32; 9%) had worse cognitive decline on global MoCA (β = -73, 95% CI -110 to -37, p = 0.00077) than all other ATNPD statuses including A+ alone (A+T-N-; n = 75; 21%). DISCUSSION In patients with early PD, CSF p-tau181 and t-tau were low compared with those in controls and did not increase over 5 years of follow-up. Our study shows that classification using modified ATNPD (incorporating CSF Aβ42, CSF p-tau181, and serum NfL) can identify biologically relevant subgroups of PD to improve prediction of cognitive decline in early PD.

Abstract
BACKGROUND Posterior cortical atrophy is a rare syndrome characterised by early, prominent, and progressive impairment in visuoperceptual and visuospatial processing. The disorder has been associated with underlying neuropathological features of Alzheimer's disease, but large-scale biomarker and neuropathological studies are scarce. We aimed to describe demographic, clinical, biomarker, and neuropathological correlates of posterior cortical atrophy in a large international cohort. METHODS We searched PubMed between database inception and Aug 1, 2021, for all published research studies on posterior cortical atrophy and related terms. We identified research centres from these studies and requested deidentified, individual participant data (published and unpublished) that had been obtained at the first diagnostic visit from the corresponding authors of the studies or heads of the research centres. Inclusion criteria were a clinical diagnosis of posterior cortical atrophy as defined by the local centre and availability of Alzheimer's disease biomarkers (PET or CSF), or a diagnosis made at autopsy. Not all individuals with posterior cortical atrophy fulfilled consensus criteria, being diagnosed using centre-specific procedures or before development of consensus criteria. We obtained demographic, clinical, biofluid, neuroimaging, and neuropathological data. Mean values for continuous variables were combined using the inverse variance meta-analysis method; only research centres with more than one participant for a variable were included. Pooled proportions were calculated for binary variables using a restricted maximum likelihood model. Heterogeneity was quantified using I2. FINDINGS We identified 55 research centres from 1353 papers, with 29 centres responding to our request. An additional seven centres were recruited by advertising via the Alzheimer's Association. We obtained data for 1092 individuals who were evaluated at 36 research centres in 16 countries, the other sites having not responded to our initial invitation to participate to the study. Mean age at symptom onset was 59·4 years (95% CI 58·9-59·8; I2=77%), 60% (56-64; I2=35%) were women, and 80% (72-89; I2=98%) presented with posterior cortical atrophy pure syndrome. Amyloid β in CSF (536 participants from 28 centres) was positive in 81% (95% CI 75-87; I2=78%), whereas phosphorylated tau in CSF (503 participants from 29 centres) was positive in 65% (56-75; I2=87%). Amyloid-PET (299 participants from 24 centres) was positive in 94% (95% CI 90-97; I2=15%), whereas tau-PET (170 participants from 13 centres) was positive in 97% (93-100; I2=12%). At autopsy (145 participants from 13 centres), the most frequent neuropathological diagnosis was Alzheimer's disease (94%, 95% CI 90-97; I2=0%), with common co-pathologies of cerebral amyloid angiopathy (71%, 54-88; I2=89%), Lewy body disease (44%, 25-62; I2=77%), and cerebrovascular injury (42%, 24-60; I2=88%). INTERPRETATION These data indicate that posterior cortical atrophy typically presents as a pure, young-onset dementia syndrome that is highly specific for underlying Alzheimer's disease pathology. Further work is needed to understand what drives cognitive vulnerability and progression rates by investigating the contribution of sex, genetics, premorbid cognitive strengths and weaknesses, and brain network integrity.

Abstract
BACKGROUND African Americans with MCI may be at increased risk for dementia compared to Caucasians. The effect of race on the efficacy of cognitive training in MCI is unclear. METHODS We used data from a two-site, 78-week randomized trial of MCI comparing intensive, home-based, computerized training with Web-based cognitive games or Web-based crossword puzzles to examine the effect of race on outcomes. The study outcomes were changes from baseline in cognitive and functional scales as well as MRI-measured changes in hippocampal volume and cortical thickness. Analyses used linear models adjusted for baseline scores. This was an exploratory study. RESULTS A total of 105 subjects were included comprising 81 whites (77.1%) and 24 African Americans (22.8%). The effect of race on the change from baseline in ADAS-Cog-11 was not significant. The effect of race on change from baseline to week 78 in the Functional Activities Questionnaire (FAQ) was significant with African American participants' FAQ scores showing greater improvements at weeks 52 and 78 (P = 0.009, P = 0.0002, respectively) than white subjects. Within the CCT cohort, FAQ scores for African American participants showed greater improvement between baseline and week 78, compared to white participants randomized to CCT (P = 0.006). There was no effect of race on the UPSA. There was no effect of race on hippocampal or cortical thickness outcomes. CONCLUSIONS Our preliminary findings suggest that web-based cognitive training programs may benefit African Americans with MCI at least as much as Caucasians, and highlight the need to further study underrepresented minorities in AD prevention trials.

Abstract
Frontotemporal dementia (FTD) is a spectrum of clinically and pathologically heterogenous neurodegenerative dementias. Clinical and anatomical variants of FTD have been described and associated with underlying frontotemporal lobar degeneration (FTLD) pathology, including tauopathies (FTLD-tau) or TDP-43 proteinopathies (FTLD-TDP). FTD patients with predominant degeneration of anterior temporal cortices often develop a language disorder of semantic knowledge loss and/or a social disorder often characterized by compulsive rituals and belief systems corresponding to predominant left or right hemisphere involvement, respectively. The neural substrates of these complex social disorders remain unclear. Here, we present a comparative imaging and postmortem study of two patients, one with FTLD-TDP (subtype C) and one with FTLD-tau (subtype Pick disease), who both developed new rigid belief systems. The FTLD-TDP patient developed a complex set of values centered on positivity and associated with specific physical and behavioral features of pigs, while the FTLD-tau patient developed compulsive, goal-directed behaviors related to general themes of positivity and spirituality. Neuroimaging showed left-predominant temporal atrophy in the FTLD-TDP patient and right-predominant frontotemporal atrophy in the FTLD-tau patient. Consistent with antemortem cortical atrophy, histopathologic examinations revealed severe loss of neurons and myelin predominantly in the anterior temporal lobes of both patients, but the FTLD-tau patient showed more bilateral, dorsolateral involvement featuring greater pathology and loss of projection neurons and deep white matter. These findings highlight that the regions within and connected to anterior temporal lobes may have differential vulnerability to distinct FTLD proteinopathies and serve important roles in human belief systems.

Abstract
PURPOSE/OBJECTIVE(S) Stereotactic radiotherapy (SR) is highly effective but has risks for serious toxicity. We sought to identify risk factors for SR plans requiring revision in a comprehensive, prospective peer review program conducted across a network of affiliated radiation centers. We hypothesized that increased physician experience and SR case volume would be associated with lower rates of SR plan revision. MATERIALS/METHODS Weekly peer review rounds were conducted to review SR cases for image fusion, contours, plan, and dose constraints, all prior to start of radiation. Cases recommended for revision were recorded and tracked prospectively. Factors potentially associated with case revision including body site, SR type, physician experience, and physician case load were assessed for significance using univariate and multivariable logistic regression. RESULTS From March 2019 to January 2023, 1,015 SR cases were prospectively reviewed, including 312 brain stereotactic radiosurgery (SRS), 190 multi-fraction brain SRS (fSRS), and 513 stereotactic body radiotherapy (SBRT). Revision was recommended in 177 cases (17%). The yearly revision rate was 21% in 2019, 16% in 2020, 17% in 2021, and 18% in 2022. There were 13 individual treating physicians with a median of 5 years' experience (range: 2-18 years), measured at the time of each SR case review. Physicians were categorized as junior (< = 2 years of experience), mid-career (3-9 years), or senior (> = 10 years). The physician's SR case volume in the preceding 3 months (median 25 cases) was dichotomized as low volume (< = 25) or high volume (>25). Logistic regression results are shown in Table 1. Statistical significance was determined by p <0.05. CONCLUSION SR plans utilizing SRS (as opposed to SBRT) and treated by physicians with high case volume had lower revision rates. Junior attendings had higher revision rates. These data imply a high value to peer review for junior attendings and for those with low SR case volume. Adequate case volume may be a critical factor for safe delivery of SR, analogous to surgical literature. Annual revision rates in the program remained stable over time, demonstrating the ongoing importance of an effective peer review program for SR.

Level I evidence supports the use of adjuvant radiotherapy (RT) and PCV chemotherapy for histologic LGG, but integration of molecular biomarkers in recent WHO classification and the emergence of temozolomide chemotherapy for gliomas necessitates additional investigation of the optimal treatment and timing of postoperative interventions. We hypothesized molecularly-defined LGG (IDH-mutant astrocytoma (astro) and IDH-mutant, 1p/19q-codeleted oligodendroglioma (oligo)) may have different clinical outcomes following adjuvant RT (aRT) with chemotherapy (aRT+chemo) vs observation or chemo alone. MATERIALS/METHODS A retrospective analysis of consecutive adult patients diagnosed with WHO Grade 2 astrocytoma or oligodendroglioma who underwent initial resection at a single institution from January 1998 to November 2017 was performed. Wilcoxon rank sum and Chi-squared tests were used to compare continuous and categorical variables, respectively. Survival analyses were performed using the Kaplan-Meier method and Cox proportional hazards models. Patients without clinical progression or death were censored at the date of last follow-up. Pre-operative and post-operative T2 FLAIR hyperintense tumor volumes were quantified using 3D Slicer to calculate extent of resection (EOR). RESULTS A total of 342 patients with molecularly-defined LGG (178 astro, 164 oligo) were identified with a median follow up of 9.1 yr. 171 (50%) patients received RT during their treatment course, of which 31 (18%) were treated with aRT within 1 year of diagnosis. The median aRT dose was 54 Gy (range: 40-60 Gy). aRT was more likely for astro (58%) vs oligo (41%, p = 0.001) and for patients who had resections with lower median EOR (88% vs 95%, p = 0.014). 53 patients (15%) were treated with chemo alone, and 136 patients (40%) were treated with aRT+chemo. Temozolomide was used for 161 patients (85%). For astro, aRT+chemo was associated with longer PFS (median 14.9 yr) compared to observation (4.8 yr, p = 0.05), aRT without chemo (5.2 yr, p = 0.01), or chemo alone (4.7 yr, p = 0.02). For oligo, aRT+chemo was associated with longer PFS (median not reached) compared to aRT without chemo (1.6 yr, p = 0.03), but not when compared to observation (median not reached, p = 0.47), or chemo alone (7.9 yr, p = 0.45). Multivariate analysis showed preoperative tumor volume, EOR, and aRT+chemo (but not aRT or chemo alone) were independently associated with astro PFS compared to observation. Propensity matching based on pre-operative tumor volume, EOR, and age demonstrated longer astro PFS after aRT+chemo (14.9 yr) compared to observation or chemo alone (4.5 yr, p = 0.015), without significant difference in OS (18.2 vs. 11.5 yr, p = 0.40). CONCLUSION Retrospective data from a single institution support the use of adjuvant radiotherapy with chemotherapy for patients with molecular astrocytomas, while the role of this approach for oligodendrogliomas is unclear in this cohort.

Abstract
PURPOSE/OBJECTIVE(S) Dual-phase PET CT, a technique by which two PET/CT scans are taken hours apart, has previously shown utility in differentiating radionecrosis (RN) from tumor progression (TP) after radiation for brain metastases. We sought to validate the utility of this technique in an independent, contemporary patient cohort. Understanding the difficulty of validation without the gold standard of pathologic confirmation in a majority of cases, we hypothesized that a dual-phase PET/CT indicating likely RN would correlate with improved overall survival (OS). MATERIALS/METHODS We performed a retrospective cohort study of all patients who received dual-phase FDG-PET between April 2015 and January 2023 at a single center for the purpose of distinguishing RN from TP in brain metastases previously treated with radiation. Scans were classified as indicating likely RN (dpPET-RN), likely TP (dpPET-TP), or unclear (dpPET-Unc) based on final radiology report. A Kaplan Meier (K-M) analysis was performed to evaluate differences in survival among the different dual-phase PET finding categories. An alpha level of 0.05 in the log-rank test was used to determine statistical significance. RESULTS We identified 36 patients who met inclusion criteria. All patients had received prior radiation - stereotactic radiosurgery (SRS), whole brain radiotherapy (WBRT) or both- to the lesion, and 21 (58%) had received surgery at some point prior to the dual phase PET CT. One patient received brachytherapy. Median time from the most recent course of radiation until dual-phase PET was 294 days, while median time from most recent surgery to dual-phase PET was 379 days. 14/36 (39%) of scans were called as dpPET-TP,15/36 (42%) were dpPET-RN, and 7/36 (19%) were dpPET-Unc. There were 10 cases where pathology was available after subsequent resection of the lesion. Five of the 10 path reports were concordant with the dual phase PET read, 5 were discordant. On K-M, median survival was 11 months (95% CI: 7.8 to 14.2 months) for dpPET-TP patients, 18 months (95% CI: 7.9 to 33.5 months) for dpPET-RN, and 12 months (95% CI: 0.0 to 51.2 months) for dpPET-Unc. On log rank testing, differences in the survival distribution for the different groups of dual-phase FDG-PET results were not statistically significant, χ2(2) = 4.085, p = .130. CONCLUSION Dual-phase PET CT has been proposed as a useful tool for distinguishing TP from RN after prior radiation. In the small subset of cases from our study with pathologic confirmation of outcomes, dual-phase PET failed to show high concordance with pathology. Although the dpPET-RN cohort had numerically superior OS compared to the dpPET-TP and dpPET-unc groups, this result was not statistically significant. Further independent validation of this imaging technique is warranted before it can be relied upon for routine clinical management.

Abstract
Obtaining the mechanical properties of soft tissues is critical in many medical fields, such as regenerative medicine and surgical simulation training. Although various tissue-characterization methods have been developed, such as AFM, indentation, and elastography, there remain some limitations on their accuracy and validity for measuring small and fragile soft tissues. This paper presents a tensile testing technique to measure the mechanical properties of soft tissues directly and accurately. Tensile testing was chosen as the primary method because of its simple procedure and ability to derive mechanical properties without requiring many assumptions or complicated models. However, tensile testing on soft tissues presents challenges related to gripping the tissue sample without affecting its inherent properties, applying minuscule forces to the sample, and measuring the cross-section area and strain of the sample. To solve these issues, this study presents a sub-micro scale tensile testing system that uses a flexure mechanism and a novel 3D-printed sample holder for gripping the tissue samples. The system also measures tested samples' cross-section area and strain using two high-resolution cameras. The system was validated by testing standard materials and used to characterize the elastic modulus, yield stress, and yield strain of lung tissue slices from six different mice. The results from the validation tests showed a less than 2.5% error for elastic modulus values measured using the tensile tester. At the same time, results from the mice lung tissue measurements revealed qualitative findings that closely matched those seen in the literature and displayed low coefficient of variation values, demonstrating the high repeatability of the system.

Abstract
This article presents a set of change management strategies found across several models and frameworks and identifies how frequently change management practitioners implement these strategies in practice. We searched the literature to identify 15 common strategies found in 16 different change management models and frameworks. We also created a questionnaire based on the literature and distributed it to change management practitioners. Findings suggest that strategies related to communication, stakeholder involvement, encouragement, organizational culture, vision, and mission should be used when implementing organizational change.

Abstract
OBJECTIVE We evaluated a point-of-care prothrombin time (PT)/international normalized ratio (INR) cartridge-based analyzer for its feasibility, accuracy, and value in critical care air transport. METHODS In this prospective study, blood samples from 10 randomly selected adult patients were tested with the cartridge during transport to determine feasibility. The cartridge results were compared with the laboratory results for the same samples. Similarly, blood samples from an additional 20 randomly selected adult patients were tested to determine test accuracy. A chart review identified 110 adult patients with PT/INR cartridge results to determine the clinical value of those results. RESULTS Data from the first group of 10 patients showed that vibration did not affect use of the cartridge. The average bias between the 2 testing methods was 0.0 INR units. A comparison of the PT/INR cartridge results and the laboratory results from the group of 20 patients showed that 73% of the cartridge values were within 0.2 of the laboratory values, 83% were within 0.4, and 93% were within 0.6. Of the 110 patients whose charts showed PT/INR cartridge results, 23% received blood products (45 trauma patients and 65 medical patients). CONCLUSION The PT/INR cartridge withstands the rigors of rotor wing transport and provides accurate, valuable results for making clinical decisions.

Abstract
Abstract
Introduction
Improved outcome measures of muscle reinnervation would facilitate clinical translation of new therapies which hope to enhance human peripheral nerve repair. Valid outcome measures should be receptive to the biological process of muscle reinnervation and correlate with clinical assessments of muscular function. This study investigated the responsiveness of volumetric MRI to the biological process of muscle reinnervation and its relationship with clinical indices of muscular function.
Method
Twenty-five patients who underwent nerve transfer to reinnervate elbow flexor muscles were followed-up at a median time of 258 days (-86 to 1698 days) post-operatively for a mean of two (one to three) volumetric MRI assessments. Medical Research Council (MRC) grade, peak volitional force (PVF), muscular fatigue, co-contraction and Stanmore Percentage of Normal Elbow Assessment (SPONEA) was also measured at each appointment. The responsiveness of each parameter was compared using Pearson or Spearman correlation as appropriate.
Results
Elbow flexor muscle volume per unit BMI demonstrated responsiveness to the biological process of muscle reinnervation (R2=0.73, p < 0.001) and correlated with patient reported impairments of reinnervated muscle; co-contraction (R2=0.63, p = 0.02) and muscle fatigue (R2=0.64, p = 0.04).
Conclusions
Volumetric MRI may is an excellent candidate as an outcome measure of muscle reinnervation.

Abstract
Intermediate band solar cells (IBSCs) promise high efficiencies while maintaining a low device structural complexity. A high efficiency can be obtained by harvesting below-band-gap photons, thus increasing the current, while at the same time preserving a high voltage. Here, we provide experimental proof that below-band-gap photons can be used to produce nonzero electrical work in an IBSC without compromising the voltage. For this, we manufacture a GaSb/GaAs quantum-dot IBSC. We use light biasing and make our cell operate at the maximum power point at 9 K. We measure the photocurrent response to absorption of photons with an energy of less than 1.15 eV while the cell is operating at 1.15 V. We also show that this result implies the existence of three quasi-Fermi levels linked to the three electronic bands in our device, as demanded by the IBSC theory to preserve the output voltage of the cell.

Abstract
STUDY DESIGN A prospective, regional, population-based study. OBJECTIVES (1) Determine the mortality rate and factors associated with it 4 years after a TSCI and (2) The point prevalence of secondary medical complications of survivors at 4 years. SETTING Communities of the Cape metropolitan area, South Africa. METHODS All persons (n = 145) sustaining a TSCI from 15 September 2013 to 14 September 2014 were eligible for follow-up at 4 years. Participants were contacted after 4 years. The next of kin, via verbal autopsy, was used to establish cause of death. Those who were alive at 4 years were asked to indicate any secondary medical complications. Logistic regression techniques were used to identify independently associated risk indicators for death and development of secondary complications, respectively. RESULTS Of the initial 145 persons, 87 were included and accounted for. Of these, 21 (24%) had died, 55 (63%) were alive and completed the survey, and 11 (13%) were classified as alive but did not submit the survey. The main cause of death reported was septicaemia (n = 7; 33%), followed by unknown natural causes (n = 7; 33%), then pressure injuries (n = 5; 24%). Out of the 55 persons alive, 89% had at least one medical complication at the time of enquiry, while more than 50% experienced 6 or more complications. The most common complications were pain (80%), muscle spasms (76%), sleeping problems (56%), and bladder dysfunction (44%). CONCLUSIONS Almost one-quarter of persons with TSCI have died 4 years after injury. Also, secondary complications were found to be highly prevalent at 4 years. This information could be used to develop secondary complications prevention programmes to reduce premature deaths. SPONSORSHIP This study was funded by the Medical Research Council of South Africa within the Research Capacity Development Initiative.

Abstract
Fetal lung interstitial tumor (FLIT) is a rare fetal malignancy that is typically diagnosed in the postnatal period, or, if recognized prenatally can mimic a benign lesion such as congenital pulmonary airway malformation. We present the earliest case of a FLIT tumor described by ultrasound and MRI at 26 weeks of gestation. Our case highlights features suggestive of FLIT including presentation later in gestation in combination with findings on fetal MRI such as a solid appearance with radiating curved bands of high signal within and along the periphery of the lesion (not as intensely high signal as the typical CPAM), possibly detailing a radiographic signature for these tumors. The role of betamethasone for these tumors is not known.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
BACKGROUND In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. METHODS All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated. RESULTS A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures. CONCLUSIONS VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

Abstract
Background Additive manufacturing has allowed for the creation of a patient-specific custom solution that can resolve many of the limitations previously reported for canine cranioplasty. The purpose of this pilot study was to determine the schedule feasibility and workflow in manufacturing patient-specific titanium implants for canines undergoing cranioplasty immediately following craniectomy. Results Computed tomography scans from patients with tumors of the skull were considered and 3 cases were selected. Images were imported into a DICOM image processing software and tumor margins were determined based on agreement between a board-certified veterinary radiologist and veterinary surgical oncologist. Virtual surgical planning was performed and a bone safety margin was selected. A defect was created to simulate the planned intraoperative defect. Stereolithography format files of the skulls were then imported into a plate design software. In collaboration with a medical solution centre, a custom titanium plate was designed with the input of an applications engineer and veterinary surgery oncologist. Plates were printed in titanium and post-processed at the solution centre. Total planning time was approximately 2 h with a manufacturing time of 2 weeks. Conclusions Based on the findings of this study, with access to an advanced 3D metal printing medical solution centre that can provide advanced software and printing, patient-specific additive manufactured titanium implants can be planned, created, processed, shipped and sterilized for patient use within a 3-week turnaround.

Abstract
Abstract
Objective
The Montreal Cognitive Assessment (MoCA) is a well-known screener of global cognitive functioning. Multiple studies have determined optimal cutoff scores for detection of cognitive impairment in various clinical populations. This study aims to determine appropriate cutoff scores in a clinically mixed bilingual (English/Spanish) sample.
Methods
A sample of n = 57 self-identified bilingual veterans referred for neuropsychological evaluation at a VA hospital completed the MoCA as part of a full battery. All tests were administered in English. The majority were male (96.4%), Hispanic/Latinx, with 14.65 mean years of education. Only MoCA total score without adding one point for ≤12 years of education was included. Descriptive statistics were used for sample characterization. ROC curve analysis assessed diagnostic accuracy of the MoCA for classification of cognitive impairment (CI). The CI group (n = 40) included both major or mild neurocognitive disorder. The nonimpaired group (n = 17) included persons with no CI or psychiatric diagnosis.
Results
ROC curve analysis was significant (p < .001) with an AUC of .857 (95% confidence interval .746-.969). A cutoff score of ≤24 was yielded an optimal balance of sensitivity (.900) and specificity (.706). Follow-up independent samples t-test and ANOVA were conducted to examine differences between groups.
Conclusions
Among bilingual individuals, a cutoff of ≤24 on the MoCA maximized sensitivity and specificity of accurately identifying cases of cognitive impairment. Findings have implications for identifying patients requiring further neuropsychological assessment.

Abstract
Abstract
Objective
The Stroop Color and Word Test is a well-known measure of executive functioning. The aim of this study is to determine if Stroop performance is impacted by bilingualism.
Method
A clinic-referred sample of veterans (n = 245; Mage = 55.84; Medu = 13.87) in whom a cognitive disorder diagnosis was ruled out were selected for inclusion. Participants self-identified as monolingual English (n = 192) or bilingual English/Spanish (n = 53) and were deemed appropriate for completing neuropsychological evaluation in English. All participants were administered the Stroop as part of a larger battery of tests. Analysis of covariance (ANCOVA) was used to examine Stroop scores across monolingual/bilingual groups, controlling for age.
Results
Stroop Word (raw) was significantly lower among bilingual participants (M = 79.13, SD = 18.24) compared to monolingual participants (M = 85.22, SD = 16.7), F = 4.48, p = .035. Although Color (F = 3.01, p = .084) and Color-Word Interference trials (F = 2.36, p = .125) were not significantly different across groups, there was a trend. When scores on the Color-Word Interference subtest were corrected using the Golden Equation, there were no significant group differences (F = .002, p = .966).
Conclusions
Bilingualism was related to reduced performance on speeded word-reading. Although there were no statistical differences on color-naming or inhibition, the sample size may have impacted statistical power. Despite this, there was no evidence of even a trend towards significance when applying the Golden Equation to correct for speed of word-reading and color-naming. Findings indicate Stroop is a valid measure of inhibitory control among bilingual individuals who are appropriate for completing testing in English, so long as adjustments are made to account for speed on the Word, Color, and Color-Word trials.

Abstract
We examined longitudinal change in language expression during a semi-structured speech sample in 48 patients with primary progressive aphasia (PPA) or behavioral variant frontotemporal dementia (bvFTD) and related this to longitudinal neuroimaging of cortical thickness available in 25 of these patients. All patient groups declined significantly on measures of both speech fluency and grammar, although patients with nonfluent/agrammatic PPA (naPPA) declined to a greater extent than patients with the semantic variant, the logopenic variant, and bvFTD. These patient groups also declined on several neuropsychological measures, but there was no correlation between decline in speech expression and decline in neuropsychological performance. Longitudinal decline in grammaticality, assessed by the number of well-formed sentences produced, was associated with longitudinal progression of gray matter atrophy in left frontal operculum/insula and bilateral temporal cortex.

Abstract
INTRODUCTION: Prior research suggests there may be gender differences with regards to hypoxia resilience. Our study was designed to determine whether there were differences between genders in neuronal electrical activity at simulated altitude and whether those changes correlated with cognitive and aviation performance decrements.METHODS: There were 60 student Naval Aviators or Flight Officers who completed this study (30 women, 30 men). Participants were exposed to increasing levels of normobaric hypoxia and monitored with dry EEG while flying a fixed-base flight simulation. Gender differences in brainwave frequency power were quantified using MATLAB. Changes in flight and cognitive performance were analyzed via simulation tasks and with a cognitive test validated under hypoxia.RESULTS: Significant decreases in theta and gamma frequency power occurred for women compared to men with insidious hypoxic exposures to 20K, with an average frequency power decrease for women of 19.4% compared to 9.3% for men in theta, and a 42.2% decrease in gamma for women compared to 21.7% for men. Beta frequency power correlated highest between genders, with an average correlation coefficient of r = 0.95 across seven channels.DISCUSSION: Results of this study suggest there is identifiable brain wave suppression for both men and women with hypoxic exposure and, moreover, there are significant differences in this suppression between genders. Beta frequency power was most sensitive for both genders and highly correlative compared to other brainwave frequencies. The implications of these findings are important considerations for next-generation aviation helmets, which may employ this technology as an early warning mechanism.Rice GM, Snider D, Drollinger S, Greil C, Bogni F, Phillips J, Raj A, Marco K, Linnville S.

Abstract
INTRODUCTION: Recently, portable dry electroencephalographs (dry-EEGs) have indexed cognitive workload, fatigue, and drowsiness in operational environments. Using this technology this project assessed whether significant changes in brainwave frequency power occurred in response to hypoxic exposures as experienced in military aviation.METHODS: There were 60 (30 women, 30 men) student Naval Aviators or Flight Officers who were exposed to an intense (acute) high-altitude (25,000 ft) normobaric hypoxic exposure, and 20 min later, more gradual (insidious) normobaric hypoxic exposure up to 20,000 ft while flying a fixed-wing flight simulation and monitored with a dry-EEG system. Using MATLAB, EEG frequencies and power were quantified and analyzed. Cognitive performance was also assessed with a cognitive task validated under hypoxia. Normobaric hypoxia and O₂ saturation (Spo₂) were produced and monitored using the Reduced Oxygen Breathing Device (ROBD2).RESULTS: Significant Spo₂ decreases were recorded at acute 25K and insidious 20K simulated altitudes. Significant power decreases were recorded in all frequencies (alpha, beta, gamma, and theta) and all channels with acute 25K exposures. Gamma, beta, and theta frequency power were significantly decreased with insidious 20K exposures at most of the channels. The frequency power decreases corresponded to significant decreases in cognitive performance and flight performance. Most importantly, frequency power suppressions occurred despite 42% of the volunteers not perceiving they were hypoxic in the acute phase, nor 20% in the insidious phase.DISCUSSION: Results suggest EEG suppression during acute/insidious hypoxia can index performance decrements. These findings have promising implications in the development of biosensors that mitigate potential in-flight hypoxic physiological episodes.Rice GM, Snider D, Drollinger S, Greil C, Bogni F, Phillips J, Raj A, Marco K, Linnville S.

Abstract
BACKGROUND The Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS®) program provides a situation-monitoring tool that allows health-care professionals to perform an environmental scan. This process includes scanning the status of the patient, team members, and the environment, to ensure that patient care is progressing toward the goal. It is assumed that health-care professionals will act in a certain way by providing feedback and support based on the scan. However, there is limited research supporting the impact of the clinical environment on behavior among health-care professionals. METHODS This qualitative research used in situ simulation and a theoretical sampling of six day and overnight shift clinical teams (n = 34) from three departments in an urban hospital in New York City: pediatric medicine, emergency medicine, and internal medicine. Notebook entries by the participants at three intervals during the case and a debriefing following the cases captured participant views, observations, and concerns about the immediate clinical environment. RESULTS In all six cases, and with every shift, there were documented examples of someone in the environment who saw something but did not speak up, possibly making a difference in regard to patient safety and the outcomes in the case. Some of the noted reasons include not wanting to be wrong, not wanting to hurt someone's feelings, or not being sure. DISCUSSION Our research explored the environmental scan that health-care team members conducted in three unique department settings, including how they perceived affordances, and the reasons why individuals may not speak up when another team member is not performing properly. Each person possesses a unique awareness and deficit of available affordances because of his/her position in the environment. Patient safety is somewhat reliant on the views and observations of each team member. Educators should use these outcomes to justify teamwork and communication training that includes targeted emphasis on providing candid feedback, situation monitoring, and mutual support.
