- Abstract
ABSTRACT Adherence to antiretroviral therapy (ART) remains sub-optimal among pregnant and postpartum women with HIV (PPWH) in high HIV prevalence low resource settings with few effective behavioral interventions. A large body of qualitative literature has established general barriers and facilitators to ART adherence in PPWH at various levels (individual, interpersonal, structural). However, research exploring the underlying behavioral mechanisms of ART adherence in PPWH with objectively verified adherence biomarkers is extremely limited. We conducted 24 in-depth interviews with postpartum women in western Kenya who had linked ART drug concentrations obtained from three dried blood spot samples across the peripartum period. Among PPWH with a low drug concentration ( n = 13) compared to those with continuously high drug concentrations ( n = 11), distinct themes emerged related to HIV status disclosure, social support, interactions with the health system, and health beliefs. By combining ART biomarkers with patient reported challenges, there is the potential for real-time interventions to support sustained ART adherence among PPWH and improve maternal and infant health outcomes.

- Abstract
Purpose: To assess the accuracy and completeness of ChatGPT-generated answers regarding uveitis description, prevention, treatment, and prognosis., Methods: Thirty-two uveitis-related questions were generated by a uveitis specialist and inputted into ChatGPT 3.5. Answers were compiled into a survey and were reviewed by five uveitis specialists using standardized Likert scales of accuracy and completeness., Results: In total, the median accuracy score for all the uveitis questions ( n = 32) was 4.00 (between "more correct than incorrect" and "nearly all correct"), and the median completeness score was 2.00 ("adequate, addresses all aspects of the question and provides the minimum amount of information required to be considered complete"). The interrater variability assessment had a total kappa value of 0.0278 for accuracy and 0.0847 for completeness., Conclusion: ChatGPT can provide relatively high accuracy responses for various questions related to uveitis; however, the answers it provides are incomplete, with some inaccuracies. Its utility in providing medical information requires further validation and development prior to serving as a source of uveitis information for patients.

- Abstract
Introduction: Socioeconomic status (SES) influences well-being among people living with HIV (people with HIV [PWH]); when individual-level SES information is not available, area-level SES indicators may be a suitable alternative. We hypothesized that (1) select ZIP code-level SES indicators would be associated with viral suppression and (2) accounting for ZIP code-level SES would attenuate racial disparities in viral suppression among PWH., Setting: The NA-ACCORD, a collaboration of clinical and interval cohorts of PWH, was used., Methods: Participants with ≥1 viral load measurement and ≥1 US residential 5-digit ZIP code(s) between 2010 and 2018 were included. In this serial cross-sectional analysis, multivariable logistic regression models were used to quantify the annual association of race and ethnicity with viral suppression, in the presence of SES indicators and sex, hepatitis C status, and age., Results: We observed a dose-response relationship between SES factors and viral suppression. Lower income and education were associated with 0.5-0.7-fold annual decreases in odds of viral suppression. We observed racial disparities of approximately 40% decreased odds of viral suppression among non-Hispanic Black compared with non-Hispanic White participants. The disparity persisted but narrowed by 3%-4% when including SES in the models., Conclusions: ZIP code-based SES was associated with viral suppression, and accounting for SES narrowed racial disparities in viral suppression among PWH in the NA-ACCORD. Inclusion of ZIP code-level indicators of SES as surrogates for individual-level SES should be considered to improve our understanding of the impact of social determinants of health and racial disparities on key outcomes among PWH in North America., Competing Interests: J.G. is an ad hoc member of HIV national advisory boards to Merck, Gilead, and ViiV Health.

- Abstract
Background: Birdshot chorioretinitis (BSCR) is a chronic bilateral posterior uveitis, which can affect central as well as peripheral vision. The aim of this study was to assess how visual acuity and visual field evolved over time in patients with BSCR., Methods: This was a prospective, observational, single-centre study based on data from the CO-BIRD cohort. Patient visits were categorised based on the time elapsed since the first symptoms, and groups of patients with different disease duration were defined. The main outcome measures were the best corrected visual acuity (BCVA), the mean deviation (MD) and the standard pattern deviation (PSD)., Results: The study included 447 Caucasian patients (181 males and 266 females), all of whom HLA-A29 carriers. From onset to 30 years of disease duration, the number of patients in each consecutive 5-year period was 237, 250, 196, 147, 78 and 32, respectively. Overall, the range of visual acuity and visual field results increased with disease duration. BCVA gradually decreased and showed a significant decline after 11-15 years after the first symptoms. Among the visual field indices, PSD significantly increased after 16-20 years, while MD showed a significant decline after 21-25 years. No major gender differences were found in visual outcomes, indicating comparable severity. The intereye correlations of MD and PSD were stronger than those of BCVA., Conclusions: BSCR resulted in a large heterogeneity of visual outcomes, which increased with time. Our data provide an overview of the visual consequences of BSCR as a function of disease duration., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Intermediate uveitis is defined as inflammation of the vitreous and pars planitis. Etiology can be infectious, associated with a systemic disease, neoplastic or idiopathic. Pars planitis is the term used for idiopathic intermediate uveitis that presents with snowballs and snowbanks. While relatively rare, intermediate uveitis is present globally and typically affects adult females. Awareness of the presentation and a dilated fundus examination in patients presenting with floaters is essential to the diagnosis. PCR testing has enhanced the ability to diagnose infectious and neoplastic conditions that masquerade as intermediate uveitis. A structured review of systems and focused imaging, and laboratory testing will assist with early diagnosis and initiation of treatment.

- Abstract
Objectives: People may experience a myriad of symptoms after mild traumatic brain injury (mTBI), but the relationship between symptoms and objective assessments is poorly characterized. This study sought to investigate the association between symptoms, resting heart rate (HR), and exercise tolerance in individuals following mTBI, with a secondary aim to examine the relationship between symptom-based clinical profiles and recovery., Methods: Prospective observational study of adults aged 18 to 65 years who had sustained mTBI within the previous 7 days. Symptoms were assessed using the Post-Concussion Symptom Scale, HR was measured at rest, and exercise tolerance was assessed using the Buffalo Concussion Bike Test. Symptom burden and symptom-based clinical profiles were examined with respect to exercise tolerance and resting HR., Results: Data from 32 participants were assessed (mean age 36.5 ± 12.6 years, 41% female, 5.7 ± 1.1 days since injury). Symptom burden (number of symptoms and symptom severity) was significantly associated with exercise intolerance ( P = .002 and P = .025, respectively). Physiological and vestibular-ocular clinical profile composite groups were associated with exercise tolerance ( P = .001 and P = .014, respectively), with individuals who were exercise intolerant having a higher mean number of symptoms in each profile than those who were exercise tolerant. Mood-related and autonomic clinical profiles were associated with a higher resting HR (>80 bpm) ( P = .048 and P = .028, respectively), suggesting altered autonomic response for participants with symptoms relating to this profile. After adjusting for age and mechanism of injury (sports- or non-sports-related), having a higher mood-related clinical profile was associated with persisting symptoms at 3 months postinjury (adjusted odds ratio = 2.08; 95% CI, 1.11-3.90; P = .013)., Conclusion: Symptom-based clinical profiles, in conjunction with objective measures such as resting HR and exercise tolerance, are important components of clinical care for those having sustained mTBI. These results provide preliminary support for the concept that specific symptoms are indicative of autonomic dysfunction following mTBI., Competing Interests: Competing interests: Prof Melinda Fitzgerald declares her role as CEO of Connectivity Traumatic Brain Injury Australia Ltd.

- Abstract
Radiosynoviorthesis is approved in several European countries and the United States to treat refractory synovitis in many inflammatory joint diseases, such as rheumatoid arthritis, spondyloarthropathies, and other arthritic joint diseases. No radiopharmaceuticals for radiosynoviorthesis are currently approved in Canada. The aim of this Health Canada-approved trial was to demonstrate the safety and efficacy of radiosynoviorthesis. Methods: Between July 2012 and November 2017, we conducted a multicenter, prospective, interventional Canadian trial. Patients ( n = 360) with synovitis refractory to standard treatments after failing 2 intraarticular glucocorticoid injections were included. They were followed up at 3, 6, and 12 mo. Outcome measures included adverse events (AEs) and clinical signs of synovitis (pain, swelling, and joint effusion) measured with the Health Assessment Questionnaire Disability Index, the Disease Activity Score, and the Visual Analog Scale. Results: In total, 392 joints were treated, including those reinjected after 6 mo ( n = 34). Of these, 83.4% (327/392) were injected with [
90 Y]Y-citrate for the knees and 9.9% (39/392) with [186 Re]Re-sulfide for medium-sized joints. Of the joints treated, 82.7% (324/392) were knees. Fifty-five AEs, most of them of mild grade, occurred and resolved without sequelae and were not life-threatening. The incidence of radiosynoviorthesis-related AEs was 9.4% (34/360). The proportion of patients showing an improvement in synovitis symptoms after radiosynoviorthesis was significant at 3 mo and was maintained up to 12 mo ( P < 0.001). Conclusion: This study confirmed the safety of radiosynoviorthesis in the treatment of patients with synovitis refractory to standard treatments. There is evidence of sustained clinical efficacy at 12 mo, suggesting that radiosynoviorthesis is an effective treatment for improving synovitis symptoms., (© 2024 by the Society of Nuclear Medicine and Molecular Imaging.)- Published

- Abstract
Aim: To describe the effectiveness and side-effect profile of adding difluprednate therapy to patients with anterior scleritis being treated systemically., Methods: Retrospective chart review. Charts from all patients with anterior scleritis who were treated with topical difluprednate in addition to systemic therapy from 1 January 2018 to 1 January 2020 were reviewed. Data collected included: demographics, scleritis type, systemic diagnosis, presence of nodules or necrosis, changes in scleritis activity, intraocular pressure (IOP), number of difluprednate drops used, type of systemic treatment used, best-corrected visual acuity (BCVA) and lens status. The primary outcome was clinical resolution of scleritis. Secondary outcomes included BCVA loss ≥2 lines, change in lens status or cataract surgery and IOP ≥24 mm Hg., Results: Thirty-two patients (44 eyes) were analysed. The median age was 57 years (IQR 52, 72); 59% were female; 72% were Caucasian. An associated systemic disease was present in 59%. Systemic therapies used when difluprednate was added were: 65% immunosuppressive agents, 43% prednisone and 25% non-steroidal anti-inflammatory drugs. The addition of difluprednate resulted in clinical resolution in 79.6% of the treated eyes. Median time to inactivity was 9 weeks (IQR 5, 20). Eyes initially using 2-4 drops per day had a higher response rate (89%, p=0.005). Over a median follow-up of 34 weeks (IQR 21, 74), 11 eyes had IOP elevation; 6 eyes lost ≥2 lines of BCVA, 5 eyes had cataract progression., Conclusion: Most eyes treated with difluprednate achieved inactivity. The addition of difluprednate to systemic therapies provides an alternative to achieve control of inflammation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objective . Photon-counting detector (PCD) CT enables routine virtual-monoenergetic image (VMI) reconstruction. We evaluated the performance of an automatic VMI energy level (keV) selection tool on a clinical PCD-CT system in comparison to an automatic tube potential (kV) selection tool from an energy-integrating-detector (EID) CT system from the same manufacturer. Approach. Four torso-shaped phantoms (20-50 cm width) containing iodine (2, 5, and 10 mg cc
-1 ) and calcium (100 mg cc-1 ) were scanned on PCD-CT and EID-CT. Dose optimization techniques, task-based VMI energy level and tube-potential selection on PCD-CT (CARE keV) and task-based tube potential selection on EID-CT (CARE kV), were enabled. CT numbers, image noise, and dose-normalized contrast-to-noise ratio (CNRd ) were compared. Main results . PCD-CT produced task-specific VMIs at 70, 65, 60, and 55 keV for non-contrast, bone, soft tissue with contrast, and vascular settings, respectively. A 120 kV tube potential was automatically selected on PCD-CT for all scans. In comparison, EID-CT used x-ray tube potentials from 80 to 150 kV based on imaging task and phantom size. PCD-CT achieved consistent dose reduction at 9%, 21% and 39% for bone, soft tissue with contrast, and vascular tasks relative to the non-contrast task, independent of phantom size. On EID-CT, dose reduction factor for contrast tasks relative to the non-contrast task ranged from a 65% decrease (vascular task, 70 kV, 20 cm phantom) to a 21% increase (soft tissue with contrast task, 150 kV, 50 cm phantom) due to size-specific tube potential adaptation. PCD-CT CNRd was equivalent to or higher than those of EID-CT for all tasks and phantom sizes, except for the vascular task with 20 cm phantom, where 70 kV EID-CT CNRd outperformed 55 keV PCD-CT images. Significance . PCD-CT produced more consistent CT numbers compared to EID-CT due to standardized VMI output, which greatly benefits standardization efforts and facilitates radiation dose reduction., (© 2024 Institute of Physics and Engineering in Medicine.)- Published

- Abstract
The group and screen (G&S) are performed in early pregnancy to identify clinically significant antibodies (CSA) that may necessitate fetal monitoring for hemolysis/anemia or affect RhIg eligibility. Guidelines vary, including differences between RhD-positive and negative patients, but typically, the G&S is repeated at 28 weeks, and sometimes pre-delivery. We reviewed data showing a low risk (0.01%-0.43%) of detecting a new CSA in late gestation (late alloimmunization) and the risk of late alloimmunization causing severe hemolysis/anemia is even lower at <0.01%. Routinely repeating a G&S at 28 weeks and delivery may not be necessary for healthy, low-risk pregnancies., (Copyright © 2024 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

- Abstract
Reference genomes of cattle and sheep have lacked contiguous assemblies of the sex-determining Y chromosome. We assembled complete and gapless telomere to telomere (T2T) Y chromosomes for these species. The pseudo-autosomal regions were similar in length, but the total chromosome size was substantially different, with the cattle Y more than twice the length of the sheep Y. The length disparity was accounted for by expanded ampliconic region in cattle. The genic amplification in cattle contrasts with pseudogenization in sheep suggesting opposite evolutionary mechanisms since their divergence 18MYA. The centromeres also differed dramatically despite the close relationship between these species at the overall genome sequence level. These Y chromosome have been added to the current reference assemblies in GenBank opening new opportunities for the study of evolution and variation while supporting efforts to improve sustainability in these important livestock species that generally use sire-driven genetic improvement strategies., Competing Interests: SK has received travel funds to speak at events hosted by Oxford Nanopore Technologies.

- Abstract
The Australian Traumatic Brain Injury Initiative (AUS-TBI) aims to co-design a data resource to predict outcomes for people with moderate-severe traumatic brain injury (TBI) across Australia. Fundamental to this resource is the data dictionary, which is an ontology of data items. Here, we report the systematic review and consensus process for inclusion of biological markers in the data dictionary. Standardized database searches were implemented from inception through April 2022. English-language studies evaluating association between a fluid, tissue, or imaging marker and any clinical outcome in at least 10 patients with moderate-severe TBI were included. Records were screened using a prioritization algorithm and saturation threshold in Research Screener. Full-length records were then screened in Covidence. A pre-defined algorithm was used to assign a judgement of predictive value to each observed association, and high-value predictors were discussed in a consensus process. Searches retrieved 106,593 records; 1,417 full-length records were screened, resulting in 546 included records. Two hundred thirty-nine individual markers were extracted, evaluated against 101 outcomes. Forty-one markers were judged to be high-value predictors of 15 outcomes. Fluid markers retained following the consensus process included ubiquitin C-terminal hydrolase L1 (UCH-L1), S100, and glial fibrillary acidic protein (GFAP). Imaging markers included computed tomography (CT) scores (e.g., Marshall scores), pathological observations (e.g., hemorrhage, midline shift), and magnetic resonance imaging (MRI) classification (e.g., diffuse axonal injury). Clinical context and time of sampling of potential predictive indicators are important considerations for utility. This systematic review and consensus process has identified fluid and imaging biomarkers with high predictive value of clinical and long-term outcomes following moderate-severe TBI.

- Abstract
Objective(s): To determine the rate of concussion diagnoses per capita recorded in hospital emergency departments in Western Australia (WA) from 2002-2018 for ICD-10-AM concussion diagnoses S06.00-S06.05, and post-concussional syndrome (PCS) (F07.2)., Design, Setting and Analysis: Retrospective analysis of hospital Emergency Department (ED) presentations and hospital admissions from all WA hospitals for all patients with an ICD-10-AM diagnosis code for concussion and post-concussional syndrome (PCS) over the period 2002-2018. Data pertaining to concussion and PCS presentations were extracted from the WA Department of Health Emergency Department Data Collection (EDDC). Total case numbers were aggregated by year (2002-2018) and regions of WA., Main Outcome Measures: The rates of diagnoses were calculated based on the population in the specific region and expressed as incidence rate per 100,000 person-years. The overall trends of diagnoses across the regions were analysed using negative binomial regression models and expressed as incidence rate ratio (IRR) with the corresponding 95 % CI, whilst adjusting for region. Tests for linearity were also performed., Results: The rate of concussion diagnosis had significantly increased linearly over the years (p for trend: p < 0.001) whilst the rate of PCS diagnosis had significantly declined linearly over the same period (p for trend: p < 0.001)., Conclusion: There was significant increase in all-cause ICD-10-AM concussion diagnoses in WA emergency departments. To further clarify the incidence and prevalence of all-cause concussion in Australia, investigation must focus on truly reflective S06.0 codes and include data linkage to primary care data. Conversely PCS ED presentations reduced; whether this relates to a change in where presentations occur for management of such a diagnosis, improved early intervention or an alternative explanation warrants further investigation., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr Gill Cowen is the Chair of the Western Australian Concussion Network and Professor Lindy Fitzgerald is the Chief Executive Officer of Connectivity, Traumatic Brain Injury Australia.

- Abstract
Abstract: The COVID-19 pandemic drastically affected health care delivery for vulnerable populations. Many facilities shifted services to telemedicine, and people with HIV or at risk of acquiring HIV experienced interruptions in care. Simultaneously, traditional training approaches to help providers adapt were disrupted. Using a mixed method approach to examine changes over time, we integrated data on trainee needs collected by the Mountain West AIDS Education and Training Center (AETC): a 10-state needs assessment survey in 2020; feedback from a 2020 community of practice; aggregate training data from 2000 to 2022; and a second survey in 2022. HIV care providers' training needs evolved from wanting support on telemedicine and COVID-19 patient care issues, to a later focus on mental health and substance use, social determinants of health, and care coordination. This integrative analysis demonstrates the vital role that AETCs can play in addressing evolving and emergent public health challenges for the HIV workforce., (Copyright © 2024 Association of Nurses in AIDS Care.)

- Abstract
Purpose: To evaluate the long-term visual acuity (VA) outcome of cataract surgery in inflammatory eye disease., Setting: Tertiary care academic centres., Design: Multicentre retrospective cohort study., Methods: A total of 1741 patients with non-infectious inflammatory eye disease (2382 eyes) who underwent cataract surgery while under tertiary uveitis management were included. Standardised chart review was used to gather clinical data. Multivariable logistic regression models with adjustment for intereye correlations were performed to evaluate the prognostic factors for VA outcomes. Main outcome measure was VA after cataract surgery., Results: Uveitic eyes independent of anatomical location showed improved VA from baseline (mean 20/200) to within 3 months (mean 20/63) of cataract surgery and maintained through at least 5 years of follow-up (mean 20/63). Eyes that achieved 20/40 or better VA at 1 year were more likely to have scleritis (OR=1.34, p<0.0001) or anterior uveitis (OR=2.2, p<0.0001), VA 20/50 to 20/80 (OR 4.76 as compared with worse than 20/200, p<0.0001) preoperatively, inactive uveitis (OR=1.49, p=0.03), have undergone phacoemulsification (OR=1.45 as compared with extracapsular cataract extraction, p=0.04) or have had intraocular lens placement (OR=2.13, p=0.01). Adults had better VA immediately after surgery, with only 39% (57/146) paediatric eyes at 20/40 or better at 1 year., Conclusions: Our results suggest that adult and paediatric eyes with uveitis typically have improved VA following cataract surgery and remain stable thereafter for at least 5 years., Competing Interests: Competing interests: JTR: AbbVie (consultant); Gilead (consultant); Janssen (consultant); Eyevensys (consultant); UpToDate (author/royalties); Pfizer (financial support); Novartis (consultant); Roche (consultant); Alcon Research Institute (financial support); Horizon (financial support and consultant); Revolo (consultant); Neoleukin (consultant); Affibody (consultant); Celgene-Bristol Myers (Data Monitoring Committee); Eli Lilly (Clinical Endpoints Committee).

- Abstract
Background: Estimating the medical complexity of people aging with HIV can inform clinical programs and policy to meet future healthcare needs. The objective of our study was to forecast the prevalence of comorbidities and multimorbidity among people with HIV (PWH) using antiretroviral therapy (ART) in the United States (US) through 2030., Methods and Findings: Using the PEARL model-an agent-based simulation of PWH who have initiated ART in the US-the prevalence of anxiety, depression, stage ≥3 chronic kidney disease (CKD), dyslipidemia, diabetes, hypertension, cancer, end-stage liver disease (ESLD), myocardial infarction (MI), and multimorbidity (≥2 mental or physical comorbidities, other than HIV) were forecasted through 2030. Simulations were informed by the US CDC HIV surveillance data of new HIV diagnosis and the longitudinal North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) data on risk of comorbidities from 2009 to 2017. The simulated population represented 15 subgroups of PWH including Hispanic, non-Hispanic White (White), and non-Hispanic Black/African American (Black/AA) men who have sex with men (MSM), men and women with history of injection drug use and heterosexual men and women. Simulations were replicated for 200 runs and forecasted outcomes are presented as median values (95% uncertainty ranges are presented in the Supporting information). In 2020, PEARL forecasted a median population of 670,000 individuals receiving ART in the US, of whom 9% men and 4% women with history of injection drug use, 60% MSM, 8% heterosexual men, and 19% heterosexual women. Additionally, 44% were Black/AA, 32% White, and 23% Hispanic. Along with a gradual rise in population size of PWH receiving ART-reaching 908,000 individuals by 2030-PEARL forecasted a surge in prevalence of most comorbidities to 2030. Depression and/or anxiety was high and increased from 60% in 2020 to 64% in 2030. Hypertension decreased while dyslipidemia, diabetes, CKD, and MI increased. There was little change in prevalence of cancer and ESLD. The forecasted multimorbidity among PWH receiving ART increased from 63% in 2020 to 70% in 2030. There was heterogeneity in trends across subgroups. Among Black women with history of injection drug use in 2030 (oldest demographic subgroup with median age of 66 year), dyslipidemia, CKD, hypertension, diabetes, anxiety, and depression were most prevalent, with 92% experiencing multimorbidity. Among Black MSM in 2030 (youngest demographic subgroup with median age of 42 year), depression and CKD were highly prevalent, with 57% experiencing multimorbidity. These results are limited by the assumption that trends in new HIV diagnoses, mortality, and comorbidity risk observed in 2009 to 2017 will persist through 2030; influences occurring outside this period are not accounted for in the forecasts., Conclusions: The PEARL forecasts suggest a continued rise in comorbidity and multimorbidity prevalence to 2030, marked by heterogeneities across race/ethnicity, gender, and HIV acquisition risk subgroups. HIV clinicians must stay current on the ever-changing comorbidities-specific guidelines to provide guideline-recommended care. HIV clinical directors should ensure linkages to subspecialty care within the clinic or by referral.

- Abstract
Background: The accurate identification of the functional elements in the bovine genome is a fundamental requirement for high-quality analysis of data informing both genome biology and genomic selection. Functional annotation of the bovine genome was performed to identify a more complete catalog of transcript isoforms across bovine tissues., Results: A total of 160,820 unique transcripts (50% protein coding) representing 34,882 unique genes (60% protein coding) were identified across tissues. Among them, 118,563 transcripts (73% of the total) were structurally validated by independent datasets (PacBio isoform sequencing data, Oxford Nanopore Technologies sequencing data, de novo assembled transcripts from RNA sequencing data) and comparison with Ensembl and NCBI gene sets. In addition, all transcripts were supported by extensive data from different technologies such as whole transcriptome termini site sequencing, RNA Annotation and Mapping of Promoters for the Analysis of Gene Expression, chromatin immunoprecipitation sequencing, and assay for transposase-accessible chromatin using sequencing. A large proportion of identified transcripts (69%) were unannotated, of which 86% were produced by annotated genes and 14% by unannotated genes. A median of two 5' untranslated regions were expressed per gene. Around 50% of protein-coding genes in each tissue were bifunctional and transcribed both coding and noncoding isoforms. Furthermore, we identified 3,744 genes that functioned as noncoding genes in fetal tissues but as protein-coding genes in adult tissues. Our new bovine genome annotation extended more than 11,000 annotated gene borders compared to Ensembl or NCBI annotations. The resulting bovine transcriptome was integrated with publicly available quantitative trait loci data to study tissue-tissue interconnection involved in different traits and construct the first bovine trait similarity network., Conclusions: These validated results show significant improvement over current bovine genome annotations., (© The Author(s) 2024.

- Abstract
High-precision searches for an electric dipole moment of the neutron (nEDM) require stable and uniform magnetic field environments. We present the recent achievements of degaussing and equilibrating the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute. We present the final degaussing configuration that will be used for n2EDM after numerous studies. The optimized procedure results in a residual magnetic field that has been reduced by a factor of two. The ultra-low field is achieved with the full magnetic-field-coil system, and a large vacuum vessel installed, both in the MSR. In the inner volume of ∼ 1.4 m 3 , the field is now more uniform and below 300 pT. In addition, the procedure is faster and dissipates less heat into the magnetic environment, which in turn, reduces its thermal relaxation time from 12 h down to 1.5 h ., (© The Author(s) 2024.)

- Abstract
We address the ethical and legal considerations for elective tubal sterilization in young, nulliparous women in Canada, with comparison with the United States and the United Kingdom. Professional guidelines recommend that age and parity should not be obstacles for receiving elective permanent contraception; however, many physicians hesitate to provide this procedure to young women because of the permanence of the procedure and the speculative possibility of regret. At the practice level, this means that there are barriers for young women to access elective sterilization; they are questioned or not taken seriously, or their desire for sterilization is more generally belittled by health care professionals. This article argues for further consideration of these requests and considers the ethical and legal issues that arise when preventing regret is prioritized over autonomy in medical practice. In Canada, there is a paucity of professional guidelines and articles offering practical considerations for handling such requests. Compared with the U.S. and U.K. policy contexts, we propose a patient-centered approach for practice to address requests for tubal sterilization that prioritizes informed consent and respect for patient autonomy. We ultimately aim to assure physicians that when the conditions of informed consent are met and documented, they practice within the limits of the law and in line with best ethical practice by respecting their patients' choice of contraceptive interventions and by ensuring their access to care., Competing Interests: Financial Disclosure Julie Thorne belongs to the Bayer Canada LNG-IUS medical advisory board and is a master trainer for Nexplanon with Organon Canada.

- Abstract
Objectives: The aim of this study was to evaluate the high-helical pitch, multienergy (ME) scanning mode of a clinical dual-source photon-counting detector (PCD) computed tomography (CT) and the benefit of virtual monoenergetic images (VMIs) for low-contrast-dose coronary CT angiography (CTA)., Materials and Methods: High-pitch (3.2) ME coronary CTA was performed in PCD-CT in 27 patients using low contrast dose (30 mL of iohexol 350 mg/mL) and in 26 patients at routine contrast dose (60 mL). Low-energy-threshold 120 kV images (also known as T3D images) and 50 kiloelectron volts (50 keV) and 100 kiloelectron volts (100 keV) VMIs were reconstructed using a 1024 × 1024 matrix and 0.6-mm slices. The CT numbers, noise, and contrast-to-noise ratio (CNR) were measured in the ascending aorta (AA), left main coronary artery (LMCA), and distal left anterior descending (LAD) artery. Confidence in grading luminal stenosis with calcific plaque, noncalcific plaque, and stent was evaluated by 2 independent readers on a 0-100 scale (0 the lowest), and a CAD-RADS score was assigned. Image contrast enhancement, sharpness, noise, artifacts, and overall image quality were rated using a 5-point ordinal scale (1 the lowest)., Results: The radiation doses (CTDI) in low- and routine-contrast cohorts were 2.5 ± 0.6 mGy and 3.1 ± 1.7 mGy, respectively ( P = 0.12). At all measured locations, the mean CT number was >300 HU in 120 kV (LMCA 382.9 ± 76.2, distal LAD 341.0 ± 53.9, AA 399.5 ± 76.1) and 50 keV images (LMCA 667.5 ± 139.9, distal LAD 578.1 ± 121.5, AA 700.8 ± 142.5) in the low-contrast cohort, with a 96% increase in CT numbers for 50 keV over 120 kV. The CT numbers were significantly higher ( P < 0.0001) in 50 keV than 120 kV and 100 keV VMI. The CNR was also significantly ( P < 0.0001) higher in 50 keV than 120 kV and 100 keV images in all vessels. Confidence in the assessment of luminal stenosis in the presence of calcific plaque was significantly higher ( P = 0.001) with the addition of 100 keV VMI (median score, 100) than using 50 keV alone (median score, 70) and 120 kV (median score, 70) for reader 1, but no significant differences were seen for reader 2 who had same median scores of 100 for all image types. The confidence in the assessment of luminal stenosis within a stent improved with the use of 100 keV images for both readers (reader 1: median scores for 50 + 100 keV = 100, 50 keV = 82.5, 120 kV = 82.5; reader 2: 50 + 100 keV = 100, 50 keV = 90, 120 kV = 90). There were no significant differences in confidence scores for assessment of luminal stenosis from noncalcific plaques for both readers. The reader-averaged qualitative scores for vascular enhancement and overall image quality were significantly higher for 50 keV VMI than for 120 kV images in both low- and routine-contrast dose cohorts. The image sharpness was nonsignificantly higher at 50 keV VMI than 120 kV images, and the artifact score was comparable for 50 keV VMI and 120 kV images. The noise was higher in 50 keV VMI than in 120 kV images., Conclusions: High-pitch ME PCD-CT mode produced diagnostic quality coronary CTA images at low radiation and iodinated contrast doses. The availability of ME VMIs significantly improved the CNR, overall image quality, and confidence in assessment of luminal stenosis in the presence of calcific plaques and stents, and resulted in change of CAD-RADS categories in 9 patients., Competing Interests: Conflicts of interest and sources of funding: Research reported in this publication was supported in part by the National Institute of Biomedical Imaging and Bioengineering of the National Institutes of Health under award number R01 EB028590.

- Abstract
Objectives: To investigate whether meticulously following a treat-to-target (T2T)-strategy in daily clinical practice will lead to less radiographic progression in patients with active RA who start (new) DMARD-therapy., Methods: Patients with RA from 10 countries starting/changing conventional synthetic or biologic DMARDs because of active RA, and in whom treatment intensification according to the T2T principle was pursued, were assessed for disease activity every 3 months for 2 years (RA-BIODAM cohort). The primary outcome was the change in Sharp-van der Heijde (SvdH) score, assessed every 6 months. Per 3-month interval DAS44-T2T could be followed zero, one or two times (in a total of two visits). The relation between T2T intensity and change in SvdH-score was modelled by generalized estimating equations., Results: In total, 511 patients were included [mean (s.d.) age: 56 (13) years; 76% female]. Mean 2-year SvdH progression was 2.2 (4.1) units (median: 1 unit). A stricter application of T2T in a 3-month interval did not reduce progression in the same 6-month interval [parameter estimates (for yes vs no): +0.15 units (95% CI: -0.04, 0.33) for 2 vs 0 visits; and +0.08 units (-0.06; 0.22) for 1 vs 0 visits] nor did it reduce progression in the subsequent 6-month interval., Conclusions: In this daily practice cohort, following T2T principles more meticulously did not result in less radiographic progression than a somewhat more lenient attitude towards T2T. One possible interpretation of these results is that the intention to apply T2T already suffices and that a more stringent approach does not further improve outcome., (© The Author(s) 2023.

- Abstract
Background: Cardiovascular changes, such as altered heart rate and blood pressure, have been identified in some individuals following mild traumatic brain injury (mTBI) and may be related to disturbances of the autonomic nervous system and cerebral blood flow., Methods: We conducted a scoping review according to PRISMA-ScR guidelines across six databases (Medline, CINAHL, Web of Science, PsychInfo, SportDiscus and Google Scholar) to explore literature examining both cardiovascular parameters and neuroimaging modalities following mTBI, with the aim of better understanding the pathophysiological basis of cardiovascular autonomic changes associated with mTBI., Results: Twenty-nine studies were included and two main research approaches emerged from data synthesis. Firstly, more than half the studies used transcranial Doppler ultrasound and found evidence of cerebral blood flow impairments that persisted beyond symptom resolution. Secondly, studies utilizing advanced MRI identified microstructural injury within brain regions responsible for cardiac autonomic function, providing preliminary evidence that cardiovascular autonomic changes are a consequence of injury to these areas., Conclusion: Neuroimaging modalities hold considerable potential to aid understanding of the complex relationship between cardiovascular changes and brain pathophysiology associated with mTBI. However, it is difficult to draw definitive conclusions from the available data due to variability in study methodology and terminology.

- Abstract
We present an apparatus that applies Ramsey's method of separated oscillatory fields to proton spins in water molecules. The setup consists of a water circuit, a spin polarizer, a magnetically shielded interaction region with various radio frequency elements, and a nuclear magnetic resonance system to measure the spin polarization. We show that this apparatus can be used for Rabi resonance measurements and to investigate magnetic and pseudomagnetic field effects in Ramsey-type precision measurements with a sensitivity below 100 pT., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

- Abstract
Objective: To describe changes in service delivery and access to rheumatologists before and during the coronavirus disease 2019 (COVID-19) pandemic periods., Methods: We conducted a population-based study in Ontario, Canada. Patient visits with rheumatologists were ascertained using billing claims data. Contact with rheumatologists was defined separately by the type of patient encounter (including office visits, telemedicine visits, and new patient consultations). Changes in the total weekly volume of encounters and monthly rates after COVID-19 public health measures were imposed were compared to expected baseline rates determined before pandemic onset (March 17, 2020)., Results: In the year prior to the pandemic, there were 289,202 patients (of which 96,955 were new consults) seen by 239 rheumatologists. In the 1 year following the pandemic onset, there were 276,686 patients (of which 86,553 were new consults) seen by 247 rheumatologists. In March 2020, there was an immediate 75.9% decrease in outpatient office visits and a rapid rise in telemedicine visits. By September 2021, 49.7% of patient encounters remained telemedicine visits. For new patient consultations, there was an immediate 50% decrease in visits at the pandemic onset, with 54.8% diverted to telemedicine visits in the first year of the pandemic versus 37.4% by September 2021. New rheumatology consultation rates continued decreasing over the study period., Conclusion: Rheumatology care delivery has shifted due to the pandemic, with telemedicine increasing sharply early in the pandemic and persisting over time. The pandemic also negatively affected access to rheumatologists, resulting in fewer new consultations and raising concerns for potential delays to diagnosis., (Copyright © 2023 by the Journal of Rheumatology.)

- Abstract
Objective: To determine if continuity of rheumatology care influences rates of emergency department (ED) visits and hospitalizations in patients with rheumatoid arthritis (RA)., Methods: A closed inception cohort of patients with RA diagnosed between 2000 and 2009 were followed until December 31, 2019. During the first 5 years following diagnosis, we categorized patients into 3 rheumatology care continuity groups (high, intermediate, and not retained in rheumatology care). Using a landmark analysis, we compared rates of ED visits and hospitalizations during follow-up. Multivariable Poisson regression models were used to estimate rate ratios (RRs), adjusting for demographics, comorbidities, and health services access and supply measures., Results: The cohort included 38,528 patients, of which 57.7% (n = 22,221) were classified in the high rheumatology continuity group, 17.2% (n = 6636) were in the intermediate group, and 25.1% (n = 9671) were not retained in rheumatology care. Relative to the high continuity group, both the intermediate and nonretention groups had higher ED rates (RR 1.14, 95% CI 1.08-1.20, and RR 1.12, 95% CI 1.08-1.16, respectively). The intermediate group also experienced higher adjusted hospitalization rates (207.4, 95% CI 203.0-211.8 per 1000 person-years [PY]) than the high continuity group (193.5, 95% CI 191.4-195.6 per 1000 PY)., Conclusion: Patients with RA with higher continuity of rheumatology care had lower rates of ED visits and hospitalizations compared to those who did not receive continuous rheumatology care during the first 5 years of follow-up. These findings provide evidence to support the value of early and continuous rheumatology care for reducing hospitalizations and ED visits., (Copyright © 2023 by the Journal of Rheumatology.)

- Abstract
Background: Preeclampsia is a major contributor to maternal and neonatal mortality worldwide. Ninety-nine percent of these deaths occur in resource limited settings. One of the greatest barriers to women seeking medical attention remains the cost of care. Kenya implemented a nation-wide policy change in 2013, offering free inpatient maternity services to all women to address this concern. Here, we explore the impact of this policy change on maternal and neonatal outcomes specific to the hypertensive disorders of pregnancy., Methods: We conducted a retrospective cross-sectional chart review of patients discharged or deceased with a diagnosis of gestational hypertension, preeclampsia, eclampsia or HELLP syndrome at a tertiary referral center in western Kenya one year before (June 1, 2012-May 31, 2013) and one year after (June 1, 2013-May 31, 2014) free maternity services were introduced at public facilities across the country. Demographic information, obstetric history, medical history, details of the current pregnancy, diagnosis on admission and at discharge, antepartum treatment, maternal outcomes, and neonatal outcomes were collected and comparisons were made between the time points., Results: There were more in hospital births after policy change was introduced. The proportion of women diagnosed with a hypertensive disorder of pregnancy was higher in the year before free maternity care although there was a statistically significant increase in the proportion of women diagnosed with gestational hypertension after policy change. Among those diagnosed with hypertensive disorders, there was no difference in the proportion who developed obstetric or medical complications. Of concern, there was a statistically significant increase in the proportion of women dying as a result of their condition. There was a statistically significant increase in the use of magnesium sulfate for seizure prophylaxis. There was no overall difference in the use of anti-hypertensives between groups and no overall difference in the proportion of women who received dexamethasone for fetal lung maturity., Conclusions: Free maternity services, however necessary, are insufficient to improve maternal and neonatal outcomes related to the hypertensive disorders of pregnancy at a tertiary referral center in western Kenya. Multiple complementary strategies acting in unison are urgently needed., (© 2023. The Author(s).)

- Abstract
Objective: To compare the image quality of ultra-high-resolution wrist CTs acquired on photon-counting detector CT versus conventional energy-integrating-detector CT systems., Materials and Methods: Participants were scanned on a photon-counting-detector CT system after clinical energy-integrating detector CTs. Energy-integrating-detector CT scan parameters: comb filter-based ultra-high-resolution mode, 120 kV, 250 mAs, Ur70 or Ur73 kernel, 0.4- or 0.6-mm section thickness. Photon-counting-detector CT scan parameters: non-comb-based ultra-high-resolution mode, 120 kV, 120 mAs, Br84 kernel, 0.4-mm section thickness. Two musculoskeletal radiologists blinded to CT system, scored specific osseous structures using a 5-point Likert scale (1 to 5). The Wilcoxon rank-sum test was used for statistical analysis of reader scores. Paired t-test was used to compare volume CT dose index, bone CT number, and image noise between CT systems. P-value < 0.05 was considered statistically significant., Results: Twelve wrists (mean participant age 55.3 ± 17.8, 6 females, 6 males) were included. The mean volume CT dose index was lower for photon-counting detector CT (9.6 ± 0.1 mGy versus 19.0 ± 6.7 mGy, p < .001). Photon-counting-detector CT images had higher Likert scores for visualization of osseous structures (median score = 4, p < 0.001). The mean bone CT number was higher in photon-counting-detector CT images (1946 ± 77 HU versus 1727 ± 49 HU, p < 0.001). Conversely, there was no difference in the mean image noise of the two CT systems (63 ± 6 HU versus 61 ± 6 HU, p = 0.13)., Conclusion: Ultra-high-resolution imaging with photon-counting-detector CT depicted wrist structures more clearly than conventional energy-integrating-detector CT despite a 49% radiation dose reduction., (© 2022.

- Abstract
We present a novel Active Magnetic Shield (AMS), designed and implemented for the n2EDM experiment at the Paul Scherrer Institute. The experiment will perform a high-sensitivity search for the electric dipole moment of the neutron. Magnetic-field stability and control is of key importance for n2EDM. A large, cubic, 5 m side length, magnetically shielded room (MSR) provides a passive, quasi-static shielding-factor of about 10 5 for its inner sensitive volume. The AMS consists of a system of eight complex, feedback-controlled compensation coils constructed on an irregular grid spanned on a volume of less than 1000 m 3 around the MSR. The AMS is designed to provide a stable and uniform magnetic-field environment around the MSR, while being reasonably compact. The system can compensate static and variable magnetic fields up to ± 50 μ T (homogeneous components) and ± 5 μ T/m (first-order gradients), suppressing them to a few μ T in the sub-Hertz frequency range. The presented design concept and implementation of the AMS fulfills the requirements of the n2EDM experiment and can be useful for other applications, where magnetically silent environments are important and spatial constraints inhibit simpler geometrical solutions., (© The Author(s) 2023.)

- Abstract
Introduction: The COVID-19 pandemic has impacted access to health services. Our objective was to understand the pandemic's impact on access to HIV, pregnancy, and family planning (FP) care among women living with HIV (WLHIV)., Methods: Data were collected after June 2020, when questions about the pandemic were added to two ongoing mixed methods studies using telephone surveys and in-depth interviews among WLHIV in western Kenya. The Chaguo Langu (CL) study includes primarily non-pregnant WLHIV receiving HIV care at 55 facilities supported by AMPATH and the Opt4Mamas study includes pregnant WLHIV receiving antenatal care at five facilities supported by FACES. Our outcomes were self-reported increased difficulty refilling medication, accessing care, and managing FP during the pandemic. We summarized descriptive data and utilized multivariable logistic regression to evaluate predictors of difficulty refilling medication and accessing care. We qualitatively analyzed the interviews using inductive coding with thematic analysis., Results: We analyzed 1,402 surveys and 15 in-depth interviews. Many (32%) CL participants reported greater difficulty refilling medications and a minority (14%) reported greater difficulty accessing HIV care during the pandemic. Most (99%) Opt4Mamas participants reported no difficulty refilling medications or accessing HIV/pregnancy care. Among the CL participants, older women were less likely (aOR = 0.95, 95% CI: 0.92-0.98) and women with more children were more likely (aOR = 1.13, 95% CI: 1.00-1.28) to report difficulty refilling medications. Only 2% of CL participants reported greater difficulty managing FP and most (95%) reported no change in likelihood of using FP or desire to get pregnant. Qualitative analysis revealed three major themes: (1) adverse organizational/economic implications of the pandemic, (2) increased importance of pregnancy prevention during the pandemic, and (3) fear of contracting COVID-19., Discussion: The two unique participant groups included in our study encountered overlapping problems during the COVID-19 epidemic. Access to HIV services and antiretrovirals was interrupted for a large proportion of non-pregnant WLHIV in western Kenya, but access to pregnancy/family planning care was less affected in our cohort. Innovative solutions are needed to ensure HIV and reproductive health outcomes do not worsen during the ongoing pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Bernard, Hassan, Humphrey, Thorne, Maina, Jakait, Brown, Yongo, Kerich, Changwony, Qian, Scallon, Komanapalli, Enane, Oyaro, Abuogi, Wools-Kaloustian and Patel.)

- Abstract
Introduction: The rollout of dolutegravir (DTG) in low- and middle-income countries was disrupted by a potential association reported with periconceptional DTG exposure among women living with HIV (WLHIV) and infant neural tube defects. This prompted countries to issue interim guidance limiting DTG use among women of reproductive potential to those on effective contraception. Data to understand the potential impact of such guidance on WLHIV are limited., Methods: We conducted a retrospective cohort analysis of WLHIV 15-49 years initiating DTG-containing antiretroviral treatment (ART) in Kenya from 2017 to 2020. We determined baseline effective (oral, injectable or lactational amenorrhea) and very effective (implant, intrauterine device or female sterilization) contraception use among women who initiated DTG before (Group 1) or during (Group 2) the interim guideline period. We defined incident contraception use in each group as the number of contraceptive methods initiated ≤180 days post-guideline (Group 1) or post-DTG initiation (Group 2). We determined the proportions of all women who switched from DTG- to non-nucleoside reverse transcriptase inhibitor (NNRTI)- (efavirenz or nevirapine) containing ART ≤12 months post-DTG initiation, compared their viral suppression (<1000 copies/ml) and conducted multivariable logistic regression to determine factors associated with switching from DTG to NNRTI-containing ART., Results: Among 5155 WLHIV in the analysis (median age 43 years), 89% initiated DTG after transitioning from an NNRTI. Baseline effective and very effective contraception use, respectively, by the group were: Group 1 (12% and 13%) and Group 2 (41% and 35%). Incident contraception use in each group was <5%. Overall, 498 (10%) women switched from DTG to an NNRTI. Viral suppression among those remaining on DTG versus switched to NNRTI was 95% and 96%, respectively (p = 0.63). In multivariable analysis, incident effective and very effective contraception use was not associated with switching., Conclusions: Baseline, but not incident, effective contraception use was higher during the interim guideline period compared to before it, suggesting women already using effective contraception were preferentially selected to initiate DTG after the guideline was released. These findings reveal challenges in the implementation of policy which ties antiretroviral access to contraceptive use. Future guidance should capture nuances of contraception decision-making and support women's agency to make informed decisions., (© 2022 The Authors.

- Abstract
We report on a search for dark matter axionlike particles (ALPs) using a Ramsey-type apparatus for cold neutrons. A hypothetical ALP-gluon coupling would manifest in a neutron electric dipole moment signal oscillating in time. Twenty-four hours of data have been analyzed in a frequency range from 23 μHz to 1 kHz, and no significant oscillating signal has been found. The usage of present dark-matter models allows one to constrain the coupling of ALPs to gluons in the mass range from 10^{-19} to 4×10^{-12} eV. The best limit of C_{G}/f_{a}m_{a}=2.7×10^{13} GeV^{-2} (95% C.L.) is reached in the mass range from 2×10^{-17} to 2×10^{-14} eV.

- Abstract
Purpose: The purpose of this study was to determine the impact of body mass index (BMI) on euploidy rates for in vitro fertilization (IVF) cycles with preimplantation genetic testing (PGT) utilizing primarily next-generation sequencing (NGS)., Methods: This retrospective cohort study included women aged ≤ 45 years who underwent IVF/PGT between September 2013 and September 2020 at a single university-affiliated fertility center. The primary outcome was euploidy rate. Secondary outcomes included peak serum estradiol (E2), number of oocytes retrieved, oocyte maturation rate, high-quality blastulation rate, clinical loss rate (CLR), clinical pregnancy rate (CPR), and ongoing pregnancy/live birth rate (OPR/LBR)., Results: The study included 1335 IVF cycles that were stratified according to BMI (normal, n = 648; overweight, n = 377; obese, n = 310). The obese group was significantly older with significantly lower baseline FSH, peak E2, high-quality blastulation rate, and number of embryos biopsied than the normal group. Overall euploidy rates were not significantly different between BMI groups (normal 36.4% ± 1.3; overweight 37.3% ± 1.8; obese 32.3% ± 1.8; p = 0.11), which persisted after controlling for covariates (p = 0.82) and after stratification of euploidy rate by age group and by number of oocytes retrieved per age group. There were no significant differences in CLR, CPR, and OPR/LBR across BMI groups., Conclusions: Despite a lower high quality blastulation rate with obesity, there is not a significant difference in euploidy rates across BMI groups in women undergoing IVF/PGT., (© 2022.

Thorne J, Hussain M, and Mantzios M
- Abstract
Background: Orthorexia nervosa (ON) is an under-researched maladaptive eating behaviour which focuses on the quality and purity of food. Mindful eating refers to being aware of what we eat by making conscious food choices. Guilt and shame are negative self-evaluative emotions which have been associated with maladaptive eating behaviours. This study explores the relationships between ON, mindful eating, and feelings of guilt and shame., Participants and Procedure: Two hundred and fifty-two participants were recruited from various online platforms, such as Facebook, Twitter, and Instagram. They were asked to complete self-report questionnaires on ON, mindful eating, and guilt and shame., Results: The findings suggested that ON was significantly negatively associated with the mindful eating subscales focused eating, hunger and satiety, and eating with awareness and significantly positively associated with guilt and shame. In addition, guilt was significantly negatively associated with focused eating, whilst both guilt and shame were significantly negatively associated with hunger and satiety and eating with awareness. Further investigation suggested that guilt and shame mediated the association between mindful eating and ON., Conclusions: It was concluded that guilt and shame could explain the association between mindful eating and ON. Limitations and future directions are discussed., (Copyright © Institute of Psychology, University of Gdansk.)

- Abstract
Objective: To provide the initial installment of a living guideline that will provide up-to-date guidance on the pharmacological management of patients with rheumatoid arthritis (RA) in Canada., Methods: The Canadian Rheumatology Association (CRA) formed a multidisciplinary panel composed of rheumatologists, researchers, methodologists, and patients. In this first installment of our living guideline, the panel developed a recommendation for the tapering of biologic and targeted synthetic disease-modifying antirheumatic drug (b/ts DMARD) therapy in patients in sustained remission using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach, including a health equity framework developed for the Canadian RA population. The recommendation was adapted from a living guideline of the Australia & New Zealand Musculoskeletal Clinical Trials Network., Results: In people with RA who are in sustained low disease activity or remission for at least 6 months, we suggest offering stepwise reduction in the dose of b/tsDMARD without discontinuation, in the context of a shared decision, provided patients are able to rapidly access rheumatology care and reestablish their medications if needed. In patients where rapid access to care or reestablishing access to medications is challenging, we conditionally recommend against tapering. A patient decision aid was developed to complement the recommendation., Conclusion: This living guideline will provide contemporary RA management recommendations for Canadian practice. New recommendations will be added over time and updated, with the latest recommendation, evidence summaries, and Evidence to Decision summaries available through the CRA website (www.rheum.ca)., (Copyright © 2022 by the Journal of Rheumatology.)

- Abstract
Background: The majority of women living in rural Kenya access antenatal care (ANC) late in pregnancy, and approximately 20% have an unmet need for family planning (FP). This study aimed to determine whether training community health volunteers (CHVs) to deliver urine pregnancy testing (UPT), post-test counselling, and referral to care was an acceptable and feasible intervention to support timely initiation of ANC and uptake of FP., Methods: We applied community-based participatory methods to design and implement the pilot intervention between July 2018 and May 2019. We conducted qualitative content analysis of 12 pre-intervention focus group discussions (FGDs) with women, men, and CHVs, and of 4 post-intervention FGDs with CHVs, each with 7-9 participants per FGD group. Using a pragmatic approach, we conducted inductive line-by-line coding to generate themes and subthemes describing factors that positively or negatively contributed to the intervention's acceptability and feasibility, in terms of participants' views and the intervention aims., Results: We found that CHV-delivered point of care UPT, post-test counselling, and referral to care was an acceptable and feasible intervention to increase uptake of ANC, FP, and other reproductive healthcare services. Factors that contributed to acceptability were: (1) CHV-delivery made UPT more accessible; (2) UPT and counselling supported women and men to build knowledge and make informed choices, although not necessarily for women with unwanted pregnancies interested in abortion; (3) CHVs were generally trusted to provide counselling, and alternative counselling providers were available according to participant preference. A factor that enhanced the feasibility of CHV delivering UPT and counselling was CHV's access to appropriate supplies (e.g. carrying bags). However, factors that detracted from the feasibility of women actually accessing referral services after UPT and counselling included (1) downstream barriers like cost of travel, and (2) some male community members' negative attitudes toward FP. Finally, improved financial, educational, and professional supports for CHVs would be needed to make the intervention acceptable and feasible in the long-term., Conclusion: Training CHVs in rural western Kenya to deliver UPT, post-test counselling, and referral to care was acceptable and feasible to men, women, and CHVs in this context, and may promote early initiation of ANC and uptake of FP. Additional qualitative work is needed to explore implementation challenges, including issues related to unwanted pregnancies and abortion, the financial burden of volunteerism on CHVs, and educational and professional supports for CHVs., (© 2022.

- Abstract
We present the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute, which features an interior cubic volume with each side of length 2.92 m, thus providing an accessible space of 25 m
3 . The MSR has 87 openings of diameter up to 220 mm for operating the experimental apparatus inside and an intermediate space between the layers for housing sensitive signal processing electronics. The characterization measurements show a remanent magnetic field in the central 1 m3 below 100 pT and a field below 600 pT in the entire inner volume, up to 4 cm to the walls. The quasi-static shielding factor at 0.01 Hz measured with a sinusoidal 2 μT peak-to-peak signal is about 100 000 in all three spatial directions and increases rapidly with frequency to reach 108 above 1 Hz.- Published

- Abstract
Background: In 2012, the US Department of Health and Human Services updated their HIV treatment guidelines to recommend antiretroviral therapy (ART) for all people with HIV (PWH) regardless of CD4 count. We investigated recent trends and disparities in early receipt of ART prescription and subsequent viral suppression (VS)., Methods: We examined data from ART-naïve PWH newly presenting to HIV care at 13 North American AIDS Cohort Collaboration on Research and Design clinical cohorts in the United States during 2012-2018. We calculated the cumulative incidence of early ART (within 30 days of entry into care) and early VS (within 6 months of ART initiation) using the Kaplan-Meier survival function. Discrete time-to-event models were fit to estimate unadjusted and adjusted associations of early ART and VS with sociodemographic and clinical factors., Results: Among 11 853 eligible ART-naïve PWH, the cumulative incidence of early ART increased from 42% in 2012 to 82% in 2018. The cumulative incidence of early VS among the 8613 PWH who initiated ART increased from 83% in 2012 to 93% in 2018. In multivariable models, factors independently associated with delayed ART and VS included non-Hispanic/Latino Black race, residence in the South census region, being a male with injection drug use acquisition risk, and history of substance use disorder (SUD; all P ≤ .05)., Conclusions: Early ART initiation and VS have substantially improved in the United States since the release of universal treatment guidelines. Disparities by factors related to social determinants of health and SUD demand focused attention on and services for some subpopulations., (Published by Oxford University Press on behalf of Infectious Diseases Society of America. 2022.)

- Abstract
Background: Accurate data on the types of healthcare people seek in the early stages following mild traumatic brain injury (mTBI) in Australia is lacking. We sought to investigate the types of healthcare people seek following mTBI, including seeking no care at all; ascertain the demographic, pre- and peri-injury factors, and symptom characteristics associated with the care that people access; and examine whether choice of care is associated with symptomatic recovery and quality of life., Methods: An online retrospective survey of Australians aged 18 to 65 years who had experienced a self-reported 'concussion' (mTBI) within the previous 18 months. Types of healthcare accessed were investigated, as well as those who did not seek any care. Data were analysed using frequency and percentages, chi-squared tests and logistic regression models., Results: A total of 201 respondents had experienced a self-reported 'concussion' but 21.4% of the respondents did not seek any care. Of the 183 respondents who sought healthcare, 52.5% attended a hospital Emergency Department, 41.0% attended a general practitioner and 6.6% accessed sports-based care. Compared to their counterparts, those who had a lower level of education (p = 0.001), had experienced previous mTBI (p = 0.045) or previous mental health issues (p = 0.009) were less likely to seek healthcare, whilst those who had experienced loss of consciousness (p = 0.014), anterograde (p = 0.044) or retrograde (p = 0.009) amnesia, and symptoms including drowsiness (p = 0.005), nausea (p = 0.040), and feeling slow (p = 0.031) were more likely to seek care. Those who did not seek care were more likely to recover within one month (AOR 4.90, 95%CI 1.51 - 15.89, p = 0.008), albeit the relatively large 95%CI warrants careful interpretation. Compared to seeking care, not seeking care was not found to be significantly associated with symptom resolution nor quality of life (p > 0.05)., Conclusions: This study provides unique insight into factors associated with healthcare utilisation in the early stages following mTBI, as well as outcomes associated with choice of care, including not seeking care. Delivering targeted community education on the signs and symptoms of mTBI, and the advantages of seeking care following injury is an important step forward in the management of this challenging condition., (© 2022.

Thorne J, Clark D, Geldenhuys L, More K, Vinson A, and Tennankore K
- Abstract
Serum amyloid A protein (AA) amyloidosis, also known as secondary amyloidosis, is a known consequence of chronic inflammation and results from several conditions including inflammatory arthritis, periodic fever syndromes, and chronic infection. AA amyloidosis can lead to multiorgan dysfunction, including changes in glomerular filtration rate and proteinuria. Definitive diagnosis requires tissue biopsy, and management of AA amyloid kidney disease is primarily focused on treating the underlying inflammatory condition to stabilize glomerular filtration rate, reduce proteinuria, and slow potential progression to kidney failure. In this narrative review, we describe the causes, pathophysiology, presentation, and pathologic diagnosis of AA amyloid kidney disease using an illustrative case of biopsy-proven AA amyloid kidney disease in a patient with long-standing rheumatoid arthritis who had a favorable response to interleukin 6 inhibition. We conclude the review with a description of established and more novel therapies for AA amyloidosis including published cases of use of tocilizumab (an interleukin 6 inhibitor) in biopsy-proven AA amyloid kidney disease., (© 2022 The Authors.)

- Abstract
Objective: The Canadian Rheumatology Association (CRA) launched the Workforce and Wellness Survey to update the Canadian rheumatology workforce characteristics., Methods: The survey included demographic and practice information, pandemic effects, and the Mini Z survey to assess burnout. French and English survey versions were distributed to CRA members electronically between October 14, 2020, and March 5, 2021. The number of full-time equivalent (FTE) rheumatologists per 75,000 population was estimated from the median proportion of time in clinical practice multiplied by provincial rheumatologist numbers from the Canadian Medical Association., Results: Forty-four percent (183/417) of the estimated practicing rheumatologists (149 adult; 34 pediatric) completed the survey. The median age was 47 years, 62% were female, and 28% planned to retire within the next 5-10 years. Respondents spent a median of 65% of their time in clinical practice. FTE rheumatologists per 75,000 population were 0.62 nationally and ranged between 0.00 and 0.70 in each province/territory. This represents a deficit of 1-78 FTE rheumatologists per province/territory and 194 FTE rheumatologists nationally to meet the CRA's workforce benchmark. Approximately half of survey respondents reported burnout (51%). Women were more likely to report burnout (OR 2.86, 95% CI 1.42-5.93). Older age was protective against burnout (OR 0.95, 95% CI 0.92-0.99). As a result of the pandemic, 97% of rheumatologists reported spending more time engaged in virtual care., Conclusion: There is a shortage of rheumatologists in Canada. This shortage may be compounded by the threat of burnout to workforce retention and productivity. Strategies to address these workforce issues are needed urgently., (Copyright © 2022 by the Journal of Rheumatology.)

- Abstract
Background and Purpose: Photon-counting detector CT is a new technology with a limiting spatial resolution of ≤150 μm. In vivo comparisons between photon-counting detector CT and conventional energy-integrating detector CT are needed to determine the clinical impact of photon counting-detector CT in temporal bone imaging., Materials and Methods: Prospectively recruited patients underwent temporal bone CT examinations on an investigational photon-counting detector CT system after clinically indicated temporal bone energy-integrating detector CT. Photon-counting detector CT images were obtained at an average 31% lower dose compared with those obtained on the energy-integrating detector CT scanner. Reconstructed images were evaluated in axial, coronal, and Pöschl planes using the smallest available section thickness on each system (0.4 mm on energy-integrating detector CT; 0.2 mm on photon-counting detector CT). Two blinded neuroradiologists compared images side-by-side and scored them using a 5-point Likert scale. A post hoc reassignment of readers' scores was performed so that the scores reflected photon-counting detector CT performance relative to energy-integrating detector CT., Results: Thirteen patients were enrolled, resulting in 26 image sets (left and right sides). The average patient age was 63.6 [SD, 13.4] years; 7 were women. Images from the photon-counting detector CT scanner were significantly preferred by the readers in all reconstructed planes ( P < .001). Photon-counting detector CT was rated superior for the evaluation of all individual anatomic structures, with the oval window (4.79) and incudostapedial joint (4.75) receiving the highest scores on a Likert scale of 1-5., Conclusions: Temporal bone CT images obtained on a photon-counting detector CT scanner were rated as having superior spatial resolution and better critical structure visualization than those obtained on a conventional energy-integrating detector scanner, even with a substantial dose reduction., (© 2022 by American Journal of Neuroradiology.)

- Abstract
We report a comprehensive evaluation of a full field-of-view (FOV) photon-counting detector (PCD) computed tomography (CT) system using phantoms, and qualitatively assess image quality in patient examples. A whole-body PCD-CT system with 50 cm FOV, 5.76 cm z-detector coverage and two acquisition modes (standard: 144 × 0.4 mm collimation and ultra-high resolution (UHR): 120 × 0.2 mm collimation) was used in this study. Phantoms were scanned to assess image uniformity, CT number accuracy, noise power spectrum, spatial resolution, material decomposition and virtual monoenergetic imaging (VMI) performance. Four patients were scanned on the PCD-CT system with matched or lower radiation dose than their prior clinical CT scans performed using energy-integrating detector (EID) CT, and the potential clinical impact of PCD-CT was qualitatively evaluated. Phantom results showed water CT numbers within ±5 HU, and image uniformity measured between peripheral and central regions-of-interests to be within ±5 HU. For the UHR mode using a dedicated sharp kernel, the cut-off spatial frequency was 40 line-pairs cm
-1 , which corresponds to a 125 μ m limiting in-plane spatial resolution. The full-width-at-half-maximum for the section sensitivity profile was 0.33 mm for the smallest slice thickness (0.2 mm) using the UHR mode. Material decomposition in a multi-energy CT phantom showed accurate material classification, with a root-mean-squared-error of 0.3 mg cc-1 for iodine concentrations (2-15 mg cc-1 ) and 14.2 mg cc-1 for hydroxyapatite concentrations (200 and 400 mg cc-1 ). The average percent error for CT numbers corresponding to the iodine concentrations in VMI (40-70 keV) was 2.75%. Patient PCD-CT images demonstrated better delineation of anatomy for chest and temporal bone exams performed with the UHR mode, which allowed the use of very sharp kernels not possible with EID-CT. VMI and virtual non-contrast images generated from a patient head CT angiography exam using the standard acquisition mode demonstrated the multi-energy capability of the PCD-CT system., (© 2021 Institute of Physics and Engineering in Medicine.)- Published

- Abstract
Background: Integrase strand transfer inhibitor (INSTI)-based combination antiretroviral therapy (cART) is associated with greater weight gain among persons with human immunodeficiency virus (HIV), though metabolic consequences, such as diabetes mellitus (DM), are unclear. We examined the impact of initial cART regimen and weight on incident DM in a large North American HIV cohort (NA-ACCORD)., Methods: cART-naive adults (≥18 years) initiating INSTI-, protease inhibitor (PI)-, or nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimens from January 2007 through December 2017 who had weight measured 12 (±6) months after treatment initiation contributed time until clinical DM, virologic failure, cART regimen switch, administrative close, death, or loss to follow-up. Multivariable Cox regression yielded adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident DM by cART class. Mediation analyses, with 12-month weight as mediator, similarly adjusted for all covariates., Results: Among 22 884 eligible individuals, 47% started NNRTI-, 30% PI-, and 23% INSTI-based cART with median follow-up of 3.0, 2.3, and 1.6 years, respectively. Overall, 722 (3%) developed DM. Persons starting INSTIs vs NNRTIs had incident DM risk (HR, 1.17 [95% CI, .92-1.48]), similar to PI vs NNRTI initiators (HR, 1.27 [95% CI, 1.07-1.51]). This effect was most pronounced for raltegravir (HR, 1.42 [95% CI, 1.06-1.91]) vs NNRTI initiators. The INSTI-DM association was attenuated (HR, 1.03 [95% CI, .71-1.49] vs NNRTIs) when accounting for 12-month weight., Conclusions: Initiating first cART regimens with INSTIs or PIs vs NNRTIs may confer greater risk of DM, likely mediated through weight gain., (© The Author(s) 2020.

- Abstract
Objective: Our study assessed the rate of new and recurrent Chlamydia trachomatis and Neisseria gonorrhoeae infections in the third trimester at an adolescent obstetrics clinic., Method: Between October 2016 and June 2020, routine third-trimester screening for C. trachomatis and N. gonorrhoeae was implemented according to new Canadian recommendations. Urine nucleic acid amplification was performed. Patient records were reviewed retrospectively, and demographic data; pregnancy and delivery characteristics; and information on screening at presentation to care, third-trimester screening (33-38 weeks), and other STI testing was recorded., Results: A total of 115 adolescents (mean age 17.90 ± 1.43 y) with 125 pregnancies presented for care. Twenty-three pregnancies were excluded (12 transferred out and 11 experienced a pregnancy loss). At presentation, screening was performed in 100 of 102 pregnancies: 64 of 100 at <13 weeks, 32 of 100 at 13-27 weeks, and 4 of 100 at 28-30 weeks. Nine tested positive for C. trachomatis and none tested positive for N. gonorrhoeae. In the third trimester, there were 3 positive C. trachomatis tests, but all were indicated: test of cure was due for 1 patient, 1 patient had a new sexual partner, and 1 patient presented with symptoms. The remaining 89 of 102 pregnancies were screened (with no other indication) and none were positive for C. trachomatis or N. gonorrhoeae. Ten patients could not be sampled (5 missed, 4 pre-term deliveries, and 1 non-compliant with testing)., Conclusion: No cases of C. trachomatis or N. gonorrhoeae infection were identified on third-trimester screening in our study. Adolescent obstetrics providers implementing Canadian screening guidelines may want to monitor their screening results to determine whether their yield warrants universal implementation., (Copyright © 2021.
