Abstract
PURPOSE There has been a UK national directive to ensure that patients are offered reconstructive surgical options. We aimed to assess any change in oncoplastic practice over a 10-year period. METHODS The surgical management of 7019 breast cancers was retrospectively assessed at Nightingale Breast Centre, Manchester University UK, from 2010 to 2019. The procedures were categorised into breast conservative surgery (BCS) and mastectomy ± immediate reconstruction. The data were analysed using inclusion and exclusion criteria. RESULTS The overall rates of BCS and mastectomy were 60.1% and 39.9% respectively. No statistically significant change in the overall rates of BCS or mastectomy was observed over the last decade (p = 0.08). The rate of simple wide local excision (WLE) decreased from 98.7% to 89.3% (p < 0.001), whilst the rate of therapeutic mammoplasty (TM) increased from 1.3% to 8% (p < 0.01). The rate of chest wall perforator flaps (CWPF) changed from zero to account for 2.7% of all BCS by 2019. The overall rate of immediate breast reconstruction (IBR) did not significantly change over the study period, but it consistently remained above the national average of 27%. The rate of implant-based IBR increased from 61.3% to 76.5% (p = 0.012), whilst the rate of Latissimus Dorsi (LD) reconstruction decreased from 26.7% to 5.1% (p < 0.05). Additionally, the rate of nipple-sparing mastectomy significantly increased from 5.2% to 24%. CONCLUSION No significant changes in the overall rates of BCS was observed, the rates of advanced breast conservation techniques, nipple-sparing mastectomy, and implant-based IBR all have increased, whilst the use of LD reconstruction decreased.

Abstract
Introduction Simultaneous anterior cruciate ligament (ACL) and ipsilateral hamstring ruptures have never been reported in the literature. The purpose of this article is to describe a treatment approach for such a case. The principles in this case can help guide treatment for any patient with concomitant ACL and hamstring pathology. Case Report We describe the case of a 53-year-old male who presented with left ipsilateral simultaneous complete proximal hamstring tendon (HT) and ACL tears after an acute tennis injury. He was successfully treated with a staged procedure, first with a proximal HT repair and later with a delayed ACL reconstruction using a bone-patellar tendon-bone autograft. Conclusion Ipsilateral simultaneous complete proximal HT and ACL tears can be successfully treated with acute proximal HT repair and delayed ACL reconstruction after rehabilitation from the HT repair. The synergistic relationship between the ACL and hamstring muscles in preventing anterior translation of the tibia necessitates staged reconstruction in the setting of a simultaneous injury.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to identify the impact of the pandemic on radiotherapy activity among members with cancer. MATERIALS/METHODS This retrospective study included fully-insured commercial members of a large national payor with cancer aged ≥18 years undergoing radiotherapy from March 1, 2018 to February 28, 2022. Radiotherapy activity was defined as the mean weekly number of treatment courses and attendances (fractions) per month pre-COVID (March 2018 to February 2020); during COVID (March 2020 to February 2021); and post-COVID (March 2021 to February 2022). T-tests assessed differences between pre-COVID and post-COVID on radiotherapy activity by age, gender, and cancer type. Interrupted time series analysis (ITS) assessed change in activity overtime, controlling for pre-COVID trends and other potential confounders. A p-value of <0.05 was considered significant. RESULTS The study included 9,275 members, 10,121 courses, and 169,257 fractions; most members were female (57%), the mean age was 57 years (SD = 12). Overall, there was a decline in mean weekly number of courses from the pre-COVID to post-COVID (-18%, p<0.05) timeframe. Females < 70 years experienced the largest decline in mean weekly number of courses (-23%, p<0.05) followed by males aged 70+ (-16%, p<0.05) and males < 70 years (-16%, p<0.05). All cancer types saw a significant decline (p<0.05); breast cancer reported the largest decline (-21%, p<0.05). Fraction numbers significantly declined overall by 27% (p<0.05) from the pre-COVID to post-COVID timeframe. The largest decline in fraction numbers was observed in females < 70 (-28%, p<0.05) followed by males < 70 years (-24%, p<0.05) and males aged 70+ (-22%, p<0.05). No difference between COVID and pre-COVID weeks for courses was observed once pre-COVID trends were accounted for using ITS. Females aged 70+ received 25% (p<0.05) fewer fractions during COVID compared to pre-COVID; a decline which continued to grow even as the pandemic eased (March 2021 to February 2022). Males aged 70+ also experienced a decreased level of fractions during the pandemic (-30%, p<0.05), but increased in the recovery period (+24%, p<0.05). Males < 70 years had an increased level of fractions during the pandemic (+14%, p<0.05). CONCLUSION Radiation mean weekly number of courses and fractions between pre-COVID and post-COVID declined with the effect more pronounced in females < 70 years. A decrease in fraction number was observed in all cancer types; specifically, breast cancer had the largest decline. ITS analysis revealed no difference between COVID and pre-COVID weeks for courses as the downward trend was already present prior to the pandemic. These findings suggest while radiotherapy courses and fractions were significantly impacted, fractionation was decreased to a greater extent, indicating an increased adoption of hypofractionation during the pandemic.

Abstract
PURPOSE/OBJECTIVE(S) Childhood cancer treatment is often costly and time intensive and may require parents/caregivers to stop working. Since 2012, several states have introduced mandatory paid family leave policies. We hypothesized that such policies, whether by reducing financial toxicity or by providing parents greater flexibility to care for their sick children, would improve outcomes among children with cancer. MATERIALS/METHODS Children ages 0-18 years diagnosed with cancer between 2010 and 2019 were identified from the Surveillance, Epidemiology, and End Results program (SEER) database. The primary outcome was overall survival (OS). The exposure of interest was state mandatory paid family leave. Difference-in-differences (DID) analyses with additive hazards regression models were utilized to compare changes in OS from pre- to post- mandatory paid sick leave policy implementation in states with vs. without paid sick leave policies. The models were adjusted for year fixed effects, state fixed effects, state Medicaid expansion status, age, race, sex, metropolitan residence status, county-level income and education, cancer site, cancer stage, and insurance status. Clustered standard errors by state were achieved via the cluster bootstrap. The plausibility of the common trends assumption was tested using event study analyses and was satisfied for all analyses. RESULTS A total of 38,053 children with cancer were identified. In adjusted difference-in-differences analyses, there was no significant change in OS in states with vs. without state mandatory paid family leave policies after policy enactment (hazard difference: 0.0001, 95% CI = -0.0002 to 0.0016, P = .47). However, among non-metropolitan residents, 1-year OS improved from 93.0% to 95.5% (2-year OS: 88.6% to 93.4%) in states with mandatory paid family leave policies compared to 92.7% to 92.5% (2-year OS: 88.0% to 87.7%) in states without such policies after policy enactment. This translates to a 2.7% improvement in 1-year OS (5.2%, 2-year OS) (hazard difference: -0.0021, 95% CI = -0.0034 to -0.0005, P = .037). There was no corresponding change for metropolitan residents (hazard DID = 0.0001, P = .47). By cancer site, the largest policy-associated improvements in survival were observed for rhabdomyosarcoma (hazard DID = -0.0037, P = .11), osteosarcoma (hazard DID = -0.0036, P<.001), and Intracranial and intraspinal embryonal tumors (hazard DID = -0.0026, P = .061). CONCLUSION State mandatory paid family leave policies were associated with improved survival for some children with cancer, most notably for those residing in non-metropolitan areas. The improvements for non-metropolitan residents may be related to alleviating otherwise increased travel burdens for cancer treatment if treatment occurs out-of-town, where working while taking care of a child is less feasible. These data also suggest a slight narrowing in rural-urban-metropolitan childhood cancer disparities associated with paid family leave policies.

Abstract
Abstract
Background Chemotherapy induced peripheral neuropathy (CIPN) is one of the most common dose-limiting side effects seen among patients with early stage breast cancer and received taxane-containing regimens. The primary clinical manifestation of CIPN is sensory neuropathy such as numbness, tingling and pain in hands and feet, which negatively affect the patient’s quality of life (QoL). Although in most patients, CIPN improves over time, in a subset of patients, it remains a substantial debilitating problem, significantly affecting QoL. To date, there are no effective prevention strategies- or sufficient treatment due to the limited understanding of CIPN pre-disposing factors or pathophysiology. We hypothesize that a multimodal integration of biomarkers with CIPN progression analysis will be required to understand the pathophysiology and to consistently predict patient susceptibility. Further, we hypothesize that this multimodal approach may be leveraged to identify targets for CIPN treatment and/or prevention. This abstract describes the study protocol used to explore this hypothesis. Objective This study is designed to 1) identify genetic, transcriptional, epigenetic, metabolic, inflammatory biomarkers predictive of CIPN development among patients with early stage breast cancer receiving a taxane containing therapy; 2) With these biomarkers, develop an algorithm to identify patients who are at risk of developing CIPN before or during taxane therapy. Methods This is a longitudinal, multicenter, observational study. Patients with early-stage breast cancer who are receiving a taxane-containing (paclitaxel, docetaxel or nab-paclitaxel) treatment regimen, without preexisting peripheral neuropathy are eligible. Estimated enrollment is 400 patients. Demographic and clinical data are collected after patients consent to participate. Molecular data and patient reported outcomes (PRO) are collected prior to initiation of taxane therapy, the 4th, 8th, and 12th week of taxane therapy, and at 3, 6, and 9 months after completion of taxane therapy. Blood samples are collected for molecular data which include genetic, transcriptional, epigenetic (DNA-methylation), and metabolic data. PRO are assessed using (i) the European Organization for Research and Treatment of Cancer CIPN20 questionnaire, (ii) the Brief Pain Inventory, (iii) the Pain Catastrophizing Scale, and (iv) the PRO Measurement System for anxiety, depression and pain interference. Initial data analysis will characterize the association of biomarkers in each modality (e.g., genetic, epigenetic, etc.) with the presence or absence of CIPN, and machine learning will be used to build candidate biomarker signatures to predict CIPN before and during taxane treatment. Two distinct multi-modal prediction models will be constructed: 1) a pre-treatment model to predict risk of developing CIPN, and 2) an on-treatment model to predict the onset of CIPN. The goal is to develop a parsimonious, clinically translatable model for robust and accurate predictions of taxane-induced CIPN. Trial Status: Active, 135 subjects enrolled. Trial Centers: 1) Cleveland Clinic Foundation (8 regional sites in Ohio and 1 in Florida); 2) Huntsman Cancer Institute, University of Utah Research Funding: National Institute of Neurological Disorder and Stroke.

Abstract
BACKGROUND Many high-income countries have seen an increase in severe perineal trauma. Teaching strategies and conditions for learning during the active second stage of labour are scarcely described. AIM To describe midwifery preceptors and midwifery students' experiences' of teaching and learning how to manage the second stage of labour, with the specific aim of preventing severe perineal trauma. METHODS A qualitative study with focus group discussions and individual in depth-interviews with preceptor midwives (n = 23) and student midwives (n = 10). Data were analysed by qualitative content analysis. RESULTS "A complex and demanding situation with mutual need for feedback, reflection and safety" was the overall theme describing the conditions. Three sub-themes were identified. "Adapting to a unique situation" refers to the difficulty of teaching and learning the aspects needed to prevent severe perineal trauma, and to provide care during this stage. "Hindering and limiting circumstances" describes teaching strategies that were perceived negatively, and how midwifery students tried to adapt to the preceptors rather than the birthing women. "A trustful and communicative relationship" describes the importance of the relationship between the student and the preceptor, where communication was a central, but not obvious part. CONCLUSION An increased awareness among preceptors is needed to optimize teaching strategies, enabling the students to focus on learning the art of the second stage of labour; supporting the woman, preventing severe perineal trauma and ensuring the safety of the unborn baby. Future research should address how existing prevention models can include training to increase preceptors' confidence in teaching.

Abstract
During inertial confinement fusion experiments at the National Ignition Facility (NIF), a capsule filled with deuterium and tritium (DT) gas, surrounded by a DT ice layer and a high-density carbon ablator, is driven to the temperature and densities required to initiate fusion. In the indirect method, 2 MJ of NIF laser light heats the inside of a gold hohlraum to a radiation temperature of 300 eV; thermal x rays from the hohlraum interior couple to the capsule and create a central hotspot at tens of millions degrees Kelvin and a density of 100-200 g/cm3. During the laser interaction with the gold wall, m-band x rays are produced at ∼2.5 keV; these can penetrate into the capsule and preheat the ablator and DT fuel. Preheat can impact instability growth rates in the ablation front and at the fuel-ablator interface. Monitoring the hohlraum x-ray spectrum throughout the implosion is, therefore, critical; for this purpose, a Multilayer Mirror (MLM) with flat response in the 2-4 keV range has been installed in the NIF 37° Dante calorimeter. Precision engineering and x-ray calibration of components mean the channel will report 2-4 keV spectral power with an uncertainty of ±8.7%.

Abstract
Abstract
Introduction
Abnormal aortic flow patterns in patients with a connective tissue disorder (CTD), such as Marfan or Loeys-Dietz syndrome, may contribute to aortic root dilation [1,2]. Valve sparing aortic root replacement, which is effective in reducing the risk of aortic dissection in case of severe dilation, may also normalize flow patterns beyond the replaced aorta and potentially slow its progressive aortic dilation.
Purpose
To assess aortic flow dynamics in patients with a CTD by 4D flow cardiovascular magnetic resonance (CMR) before and after valve sparing aortic root replacement, and to compare the results with those of healthy volunteers (HV).
Methods
Patients with Marfan or Loeys-Dietz syndrome underwent two non-contrast enhanced 4D flow CMR, one before and another after undergoing valve sparing aortic root replacement. Healthy volunteers matched for age, sex and BSA were also included for comparison. Maximum velocity, in-plane rotational flow (IRF), systolic flow reversal ratio (SFRR) and wall shear stress (WSS) magnitude and its axial and circumferential components were obtained at 24 planes covering the thoracic aorta from the sinotubular junction to the descending aorta at the diaphragmatic level [3–5].
Results
Sixteen patients and 21 healthy volunteers were included. Demographic and clinical data is presented in Table. The mean time between the CMR prior and posterior to surgery was 15 months. Compared to HV, patients with CTD before intervention presented lower maximum velocity at the proximal ascending aorta (Fig. 1A), lower IRF and circumferential WSS at the arch and the proximal descending aorta (Fig. 1B and F), lower magnitude and axial WSS at the proximal ascending and descending aorta (Fig. 1E and D), and increased SFRR at the proximal descending aorta (Fig. 1C). The intervention completely restored maximum velocity and partially-restored physiological helical flow and circumferential WSS, but barely improved axial WSS and SFRR.
Conclusion
Valve sparing aortic root replacement in patients with Marfan or Loeys-Dietz syndrome partially restore to physiological level both in-plane rotational flow and circumferential wall shear stress in the descending aorta. This flow normalization may contribute to prevent progressive dilation after the surgery.

Abstract
Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Abstract
We use single photon detectors to probe the motional state of a superfluid ^{4}He resonator of mass ∼1 ng. The arrival times of Stokes and anti-Stokes photons (scattered by the resonator's acoustic mode) are used to measure the resonator's phonon coherences up to the fourth order. By postselecting on photon detection events, we also measure coherences in the resonator when ≤3 phonons have been added or subtracted. These measurements are found to be consistent with predictions that assume the acoustic mode to be in thermal equilibrium with a bath through a Markovian coupling.

Abstract
OBJECTIVE This study aimed to evaluate and quantify the relationship between coffee and gastric cancer using a uniquely large dataset from an international consortium of observational studies on gastric cancer, including data from 18 studies, for a total of 8198 cases and 21 419 controls. METHODS A two-stage approach was used to obtain the pooled odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for coffee drinkers versus never or rare drinkers. A one-stage logistic mixed-effects model with a random intercept for each study was used to estimate the dose-response relationship. Estimates were adjusted for sex, age and the main recognized risk factors for gastric cancer. RESULTS Compared to never or rare coffee drinkers, the estimated pooled OR for coffee drinkers was 1.03 (95% CI, 0.94-1.13). When the amount of coffee intake was considered, the pooled ORs were 0.91 (95% CI, 0.81-1.03) for drinkers of 1-2 cups per day, 0.95 (95% CI, 0.82-1.10) for 3-4 cups, and 0.95 (95% CI, 0.79-1.15) for five or more cups. An OR of 1.20 (95% CI, 0.91-1.58) was found for heavy coffee drinkers (seven or more cups of caffeinated coffee per day). A positive association emerged for high coffee intake (five or more cups per day) for gastric cardia cancer only. CONCLUSIONS These findings better quantify the previously available evidence of the absence of a relevant association between coffee consumption and gastric cancer.

Abstract
The extensive published works of Hedley Herbert Finlayson provide a major and widely recognised benchmark in the study of Australian mammals during the first half of the 1900s. His publications are still commonly cited in the literature, especially in relation to studies concerning the desert regions, but little has been documented of his extensive and extremely valuable private collection of almost 3000 expertly prepared study specimens. This paper provides a brief background to the man and reports a compilation of his surviving specimens, giving information on quantities, type and geographic origin of specimens, nomenclature and accession numbers. A transcription of his original register of specimens is also provided.

Abstract
INTRODUCTION The retina and brain exhibit similar pathologies in patients diagnosed with neurodegenerative diseases. The ability to access the retina through imaging techniques opens the possibility for non-invasive evaluation of Alzheimer's disease (AD) pathology. While retinal amyloid deposits are detected in individuals clinically diagnosed with AD, studies including preclinical individuals are lacking, limiting assessment of the feasibility of retinal imaging as a biomarker for early-stage AD risk detection. METHODS In this small cross-sectional study we compare retinal and cerebral amyloid in clinically normal individuals who screened positive for high amyloid levels through positron emission tomography (PET) from the Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) trial as well as a companion cohort of individuals who exhibited low levels of amyloid PET in the Longitudinal Evaluation of Amyloid Risk and Neurodegeneration (LEARN) study. We quantified the number of curcumin-positive fluorescent retinal spots from a small subset of participants from both studies to determine retinal amyloid deposition at baseline. RESULTS The four participants from the A4 trial showed a greater number of retinal spots compared to the four participants from the LEARN study. We observed a positive correlation between retinal spots and brain amyloid, as measured by the standardized uptake value ratio (SUVr). DISCUSSION The results of this small pilot study support the use of retinal fundus imaging for detecting amyloid deposition that is correlated with brain amyloid PET SUVr. A larger sample size will be necessary to fully ascertain the relationship between amyloid PET and retinal amyloid both cross-sectionally and longitudinally.

Background
Bicuspid aortic valve (BAV), a congenital heart defect, is associated with ascending aorta dilation, possibly via alteration of aortic blood flow [1]. In BAV abnormal flow condition have been associated with aortic extracellular matrix dysregulation and elastic fiber degeneration [2]. Current morphological classification of BAV patients with aortic valve with a single fusion between two adjacent leaflets does not allow for risk stratification.
Purpose
This research work tested whether the extent of fusion between leaflets is related to AAo diameter and flow alterations.
Methods
Ninety BAV patients free from moderate and severe aortic valve disease and with no previous aortic or aortic valve surgery or replacement were prospectively enrolled. A comprehensive magnetic resonance protocol comprised a stack of double-oblique 2D balanced steady-state free-precession (bSSFP) cine CMR of the aortic valve, which was used to measure the length of the fusion between leaflets, a cine CMR at the level of the pulmonary bifurcation to assess aortic diameter and 4D flow MRI sequence to assess flow characteristics and regional stiffness [3]. Jet angle and flow radial displacement, quantifying the extent of flow eccentricity, and systolic flow reversal ratio (SFRR), assessing the relative amount of backward flow during systole, were computed at 8 equidistant planes in the ascending aorta and 4 equidistant planes in the aortic arch [4]. A two-tailed p-value < 0.05 was considered statistically significant.
Results
The length of leaflet fusion varied widely (median 7.7 mm, inter-quartile range [5.5; 10.2]), Table 1). In bivariate analysis, fusion length was also associated to ascending aortic diameter (R = 0.391, p < 0.001), age (R = 0.313, p = 0.005) and body surface area (R = 0.396, p < 0.001). It was also positively related to flow abnormalities: like displacement in the proximal and distal ascending aorta, jet angle in the mid ascending aorta, and SFRR in the ascending aorta and the aortic arch (see Figure 1). The association between fusion length and ascending aorta diameter persisted in multivariate analysis after correction for age (p = 0.006).
Conclusions
Bicuspid aortic valve fusion extent varies greatly and it is associated with aortic diameter, possibly through flow alterations. Prospective longitudinal studies are needed to establish whether fusion length may allow for risk stratification in bicuspid aortic valve patients.

BACKGROUND
Loeys-Dietz (LDS) and Marfan (MFS) syndromes are rare genetic connective tissue disorders associated with progressive aortic dilation, however, aortic dissections have been observed at lower aortic root diameters in LDS than in MFS. Recent CMR studies in MFS patients reported increased aortic stiffness (1–3) and altered rotational flow (4), but research on aortic flow dynamics and biomechanics in LDS is lacking.
PURPOSE
The aim of this study was to assess rotational aortic flow and aortic stiffness in LDS compared to healthy volunteers (HV) and MFS patients, using 4Dflow CMR.
METHODS
Twenty-one LDS and 44 MFS patients, without previous aortic dissection or surgery, and 43 HV underwent a non-contrast-enhanced 4D flow CMR. Aortic stiffness was quantified at the AAo and DAo using pulse wave velocity (PWV). In-plane rotational flow (IRF), systolic flow reversal ratio (SFRR) (5) and local aortic diameters were obtained at 20 equidistant planes from the ascending (AAo) to the proximal descending aorta (DAo).
RESULTS
LDS patients had lower IRF at the distal AAo and proximal DAo compared to HV (p = 0.053 and 0.004, respectively), once adjusted for age, stroke volume and local aortic diameter; but no differences were found with respect to MFS (Figure). Although SFRR at the proximal DAo was increased in LDS patients compared to both HV (p = 0.037) and MFS populations (p = 0.015), once adjusted for age and aortic diameter, the difference in magnitude was small (Figure). On the other hand, AAo and DAo PWV revealed stiffer aortas in LDS patients compared to HV but no differences versus MFS patients (Table).
CONCLUSIONS
Patients with Loeys-Dietz syndrome showed decreased in-plane rotational flow and abnormally-high regional aortic stiffness compared to healthy controls, and similar hemodynamics and aortic stiffness with respect to patients with Marfan syndrome.

Abstract
OBJECTIVES To evaluate the impact of government HIV strategies that aimed to increase HIV testing uptake and frequency among gay and bisexual men (GBM) in New South Wales (NSW), Australia. DESIGN We analysed HIV testing data from existing passive and sentinel surveillance systems between 2010 and 2018. METHODS Six indicators were measured: (1) state-wide total HIV laboratory tests; (2) number of GBM attending publicly-funded clinics; (3) 12-monthly testing uptake; (4) annual testing frequency; (5) HIV testing with a STI diagnosis; and (6) HIV positivity. Mathematical modelling was used to estimate (7) the proportion of men with undiagnosed HIV. Indicators were stratified by Australian vs. overseas-born. RESULTS Overall, 43,560 GBM attended participating clinics (22,662 Australian-born, 20,834 overseas-born) from 2010-2018. Attendees increased from 5,186 in 2010 to 16,507 in 2018. There were increasing trends (p<0.001 for all) in testing uptake (83.9% to 95.1%); testing with a STI diagnosis (68.7% to 94.0%); annual HIV testing frequency (1.4 to 2.7); and a decreasing trend (p<0.01) in HIV positivity (1.7% to 0.9%).Increases in testing were similar in Australian-born and overseas-born GBM. However, there were decreasing trends in the estimated undiagnosed HIV proportion overall (9.5% to 7.7%) and in Australian-born GBM (7.1% to 2.8%), but an increasing trend in overseas-born GBM (15.3% to 16.9%) (p<0.001 for all).

Introduction
The aorta is a 3D hollow, curvilinear elastic structure whose diseases have life-threatening consequences. Despite much effort has been paid to study aortic diameter, diameter is a poor predictor of events. Conversely, much less is known about aortic curvature, its distribution in the thoracic aorta and the potential impact of risk factors in aneurysms associated with different conditions. Currently, 4D flow magnetic resonance imaging (4D flow CMR) allows to obtain 3D geometry, 4D flow data and regional aortic stiffness.
Purpose
We aim to study regional aortic curvature in thoracic aorta aneurysms of different aetiologies and define its relationship with established risk factors.
Methods
One-hundred twenty patients (40 for each group, selected out of prospective cohorts of 156 bicuspid aortic valve – BAV-, 77 Marfan –MFS- and 67 patients with a degenerative aneurysm – TAVdeg-) were matched for age, sex and BSA via propensity score with 40 healthy volunteers (HV). The thoracic aorta was semi-automatically segmented from angiograms and the centreline was computed. Local curvature was assessed at 20 planes covering the thoracic aorta from the sinotubular junction to the proximal descending aorta (DAo) at the level of the pulmonary artery bifurcation. Local curvature was normalized by subject mean thoracic aorta curvature. Length was measured as centreline length. Aortic stiffness was measured in the DAo by pulse wave velocity (PWV). Aneurysm was defined by z-score ≥ 2 using diameters measured by double-oblique cine CMR.
Results
Matching was successful in all groups with the exception of a residual age difference between HV and TAVdeg. Curvature in HV showed a fairly smooth transition between the straighter ascending aorta (AAo) and DAo to a more curved aortic arch, with a peak in the mid aortic arch (Figure 1A). Conversely, all patients’ groups presented a peak in curvature in the proximal DAo and a decreased local curvature in the aortic arch and mid DAo close to the level of the pulmonary artery. BAV and TAVdeg patients showed also increased curvature in the mid AAo, were dilation is prevalent. Conversely, in the same area MFS showed a reduced curvature and limited prevalence of aneurysm. In the overall population, age, AAo and root diameters, mean blood pressure, DAo PWV and aortic length, all established risk factors for aortic events, were inversely related to curvature in the distal AAo and aortic arch (Figure 1B).
Conclusions
Aneurysms related to different aetiologies show similar abnormalities in aortic curvature, with limited curvature in the aortic arch and a peak soon after the third supra-aortic vessel. Age, aortic diameter, length, stiffness and blood pressure, all known risk factors, are all related to reduced curvature in the distal ascending aorta and aortic arch.

Abstract
A diverse range of platforms has been established to increase the efficiency and speed of clinical trials for Alzheimer's disease (AD). These platforms enable parallel assessment of multiple therapeutics, treatment regimens, or participant groups; use uniform protocols and outcome measures; and may allow treatment arms to be added or dropped based on interim analyses of outcomes. The EU/US CTAD Task Force discussed the lessons learned from the Dominantly Inherited Alzheimer's Network Trials Unit (DIAN-TU) platform trial and the challenges addressed by other platform trials that have launched or are in the planning stages. The landscape of clinical trial platforms in the AD space includes those testing experimental therapies such as DIAN-TU, platforms designed to test multidomain interventions, and those designed to streamline trial recruitment by building trial-ready cohorts. The heterogeneity of the AD patient population, AD drugs, treatment regimens, and analytical methods complicates the design and execution of platform trials, yet Task Force members concluded that platform trials are essential to advance the search for effective AD treatments, including combination therapies.

Abstract
Abstract
Background
Pulmonary embolism (PE) is a life-threatening cardiovascular condition. Studies showed that PE patients were associated with disorders of lipid metabolism and had higher triglyceride and lower HDL-C levels compared with healthy. We conducted the genome-wide association study to identify novel loci contributing to PE.
Methods
We conducted a large-scale GWAS of PE in 5,466 PE cases and 461,219 controls of European ancestry from the UK Biobank (466,685 participants total). We used genome-wide summary statistics to test for enrichment of functional annotations using ENRICHR. Example pathways included in Enrichr for testing include membership of genes in pathway databases such as the Kyoto Encyclopedia of Genes and Genomes (KEGG), Wikipathway, PANTHER, BioCarta or NCI-Nature pathways. We analyzed the pathways using combined score and p-values which were well validated by comparing to several methods. For pathway analyses, we considered a nominal P-value threshold of 0.05.
Results
We identified genome-wide significant genetic associations in 63 independent genetic loci for PE (P<5.0x10–7). Our findings for top pathways highlight that lipid metabolism (LIPC, LCAT, NPC2), caffeine metabolism (NAT2), and sudden cardiac death (ABCG8) related genetic loci play an important role in PE alongside genes already associated with coagulation-thrombosis pathway (VWF, THPO, PTPN11, INPP5D, UROS, HMBS) (all p-values p-values <0.05).
Conclusion
Our findings uncovered unexpected novel factors of PE etiology, suggesting novel mechanistic concepts of PE pathophysiology.

Abstract
Abstract
Background
Connective tissue disorders, such as Loeys-Dietz (LDS) and Marfan (MFS) syndromes, are rare genetic diseases associated with progressive aortic dilation. Aortic dissections have been observed at lower aortic root diameters in LDS than in MFS, and research on aortic flow dynamics and biomechanics in LDS is lacking.
Purpose
To evaluate rotational aortic flow and aortic stiffness in LDS compared to healthy volunteers (HV) and MFS patients, using 4Dflow CMR.
Methods
Twenty-one LDS and 44 MFS patients, without previous aortic dissection or surgery, and 44 HV underwent a non-contrast-enhanced 4D flow CMR. In-plane rotational flow (IRF), systolic flow reversal ratio (SFRR) and local aortic diameters were obtained at 20 equidistant planes from the ascending (AAo) to the proximal descending aorta (DAo). Aortic stiffness was quantified at the AAo and DAo using pulse wave velocity (PWV).
Results
LDS patients had lower IRF at the distal AAo and proximal DAo compared to HV (p=0.053 and 0.004, respectively), once adjusted for age, stroke volume and local aortic diameter; but no differences were found with respect to MFS (Figure). Although SFRR at the proximal DAo was increased in LDS patients compared to both HV (p=0.037) and MFS populations (p=0.015), once adjusted for age and aortic diameter, the difference in magnitude was small (Figure). On the other hand, AAo and DAo PWV revealed stiffer aortas in LDS patients compared to HV but no differences versus MFS patients (Table).
Conclusions
LDS patients showed decreased in-plane rotational flow and abnormally-high regional aortic stiffness compared to healthy controls, and similar hemodynamics and aortic stiffness with respect to MFS patients

Abstract
Abstract
Objective
To determine whether performance on the Latin American Spanish version of the Face-Name Associative Memory Exam (LAS-FNAME) can differentiate between cognitively intact carriers of an autosomal dominant Alzheimer’s disease mutation (E280A) in Presenilin-1, who are destined to develop early-onset dementia, from matched non-carriers. We also sought to examine whether LAS-FNAME performance is associated with amyloid-β and regional tau burden in mutation carriers.
Methods
35 cognitively intact mutation carriers (age range 26–41), 48 matched non-carriers (aged 27 to 44), and 19 symptomatic carriers (13 with subjective cognitive concerns, 6 with mild cognitive impairment [MCI]) completed the LAS-FNAME. A subset of participants (31 carriers [12 symptomatic] and 35 non-carriers) traveled from Colombia to Boston to undergo positron emission tomography (PET) using Pittsburgh compound B to measure mean cortical amyloid-β and Flortaucipir for regional tau tangles. ANOVA analyses and Spearman correlations were used to examine group differences and relationships among LAS-FNAME performance, Aβ and tau accumulation.
Results
Compared to non-carriers, cognitively intact carriers had lower scores on the LAS-FNAME total scores (p = .040). Across all carriers (including symptomatic carriers), higher levels of amyloid-β (r = −.436, p = .018) and regional tau in the entorhinal (r = −.394, p = .031) and inferior temporal cortex (r = −.563, p = .001) were associated with lower LAS-FNAME total scores (see Figure).
Conclusions
Performance on the LAS-FNAME differentiated between cognitively intact mutation carriers from non-carriers, and was associated with greater amyloid and tau burden when examining all carriers. Findings suggest that the LAS-FNAME is sensitive to early clinical and pathological changes and can potentially help track disease progression in Spanish-speaking individuals.

Abstract
Efforts to develop effective disease-modifying treatments for Alzheimer's disease (AD) have mostly targeted the amyloid β (Aβ) protein; however, there has recently been increased interest in other targets including phosphorylated tau and other forms of tau. Aggregated tau appears to spread in a characteristic pattern throughout the brain and is thought to drive neurodegeneration. Both neuropathological and imaging studies indicate that tau first appears in the entorhinal cortex and then spreads to the neocortex. Anti-tau therapies currently in Phase 1 or 2 trials include passive and active immunotherapies designed to prevent aggregation, seeding, and spreading, as well as small molecules that modulate tau metabolism and function. EU/US/CTAD Task Force members support advancing the development of anti-tau therapies, which will require novel imaging agents and biomarkers, a deeper understanding of tau biology and the dynamic interaction of tau and Aβ protein, and development of multiple targets and candidate agents addressing the tauopathy of AD. Incorporating tau biomarkers in AD clinical trials will provide additional knowledge about the potential to treat AD by targeting tau.
