    Abstract Purpose: Goal attainment scaling (GAS) has been proposed as a person-centric, semi-quantitative measure that assimilates achievement of individually set goals into a single standardized "goal attainment score" that can be compared at the population level. We aimed to examine the reliability and validity of the Japanese version of the GAS for depression (GAS-D) tool in assessing goal attainment in people living with major depressive disorder (MDD).
    Patients and methods: This was a prespecified analysis of a prospective, 24-week, multicenter, observational cohort study of employed Japanese outpatients with MDD initiating treatment with vortioxetine according to the Japanese label (JRCT1031210200). Participants were assessed using the Japanese version of the GAS-D and other clinical rating scales at baseline and Weeks 8, 12 and 24.
    Results: Goal attainment was significantly associated with symptom severity as assessed by the Montgomery-Åsberg Depression Rating Scale (MADRS) scale, confirming convergent validity. In particular, GAS-D scores were significantly related to MADRS total score at Weeks 12 and 24, indicating that improvements in overall symptom severity with vortioxetine treatment were likely to be reflected in the achievement of individualized treatment goals. With an intraclass correlation coefficient of 0.67 (95% CI 0.45-0.82), the GAS-D also showed moderate test-retest reliability between Weeks 8 and 12 while proving independent of demographic characteristics.
    Conclusion: The results of this open-label study support the use of the GAS-D as a valid and sensitive outcome measure in the assessment of treatment response in MDD.

    Abstract Purpose: Our objective was to develop a methodology for assessing the linear energy transfer (LET) and relative biological effectiveness (RBE) in clinical proton and helium ion beams using fluorescent nuclear track detectors (FNTDs).
    Methods and materials: FNTDs were exposed behind solid water to proton and helium (
    Results: For protons, average relative differences between measurements and simulations were 6% and 19% for LET
    Conclusions: This study demonstrates for the first time that FNTDs can be used to perform direct LET measurements and to estimate the RBE in clinical proton and helium ion beams.

    Abstract Introduction: More than every third patient experiences recurrent atrial fibrillation after surgical pulmonary vein ablation. However, it remains challenging to predict who will and who will not experience this event. Scoring systems containing baseline risk factors have been proposed as a complementary tool to identify patients at higher risk of experiencing atrial fibrillation recurrence. Therefore, the aim of this study was to assess the value of the scoring systems APPLE, CHA
    Methods: In a retrospective study, we identified all patients undergoing concomitant pulmonary vein ablation during cardiac surgery. APPLE-, CHA
    Results: Receiver operating characteristic curves showed the superiority of the APPLE scoring system with an area under the curve of 0.690 compared to 0.571 for CHA
    Conclusions: The APPLE scoring system is superior to CHA

    Abstract A 23-year-old female patient presented with radicular back pain, perineal numbness, and urinary retention. The patient was diagnosed with cauda equina syndrome and magnetic resonance imaging (MRI) of the spine revealed an enhancing osseous lumbar lesion causing severe central stenosis. A core needle biopsy of the lumbar spine showed microscopic features compatible with a small round blue cell tumor. CD99 and FLI1 were positive in the tumor cells.

    Abstract Hospitalisation with COVID-19 is associated with an increased risk of neurological sequelae; however, representative nationwide studies comparing to other infections with similar severity and also including milder SARS-CoV-2 infections have been lacking. Using the nationwide Danish registers including all SARS-CoV-2 PCR test results and hospitalisations between March 1, 2020, and December 31, 2021, we estimate the risk of any first neurological disorder diagnosed in inpatient, outpatient, or emergency room settings. We show that positive tests increase the rate of neurological disorders by a hazard ratio of 1.96 (95% confidence interval: 1.88-2.05) compared to individuals not tested and by a hazard ratio of 1.11 (95% confidence interval: 1.07-1.16) compared to individuals with negative tests only. However, there is no evidence that the risk of neurological disorders is higher for individuals who test positive compared to non-COVID-19 infections treated with anti-infective medication. The risk of neurological disorders is increased after COVID-19-hospitalisation compared to no COVID-19 hospital admission; however, these risks are comparable to hospitalisation with other respiratory infections (P value 0.328). In conclusion, COVID-19 is associated with an increased risk of neurological disorders, but no more than that observed after other infections of similar severity.

    Abstract Importance: Psychiatric outcomes after COVID-19 have been of high concern during the pandemic; however, studies on a nationwide level are lacking.
    Objective: To estimate the risk of mental disorders and use of psychotropic medication among individuals with COVID-19 compared with individuals not tested, individuals with SARS-CoV-2-negative test results, and those hospitalized for non-COVID-19 infections.
    Design, setting, and participants: This nationwide cohort study used Danish registries to identify all individuals who were alive, 18 years or older, and residing in Denmark between January 1 and March 1, 2020 (N = 4 152 792), excluding individuals with a mental disorder history (n = 616 546), with follow-up until December 31, 2021.
    Exposures: Results of SARS-CoV-2 polymerase chain reaction (PCR) testing (negative, positive, and never tested) and COVID-19 hospitalization.
    Main outcomes and measures: Risk of new-onset mental disorders (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, codes F00-F99) and redeemed psychotropic medication (Anatomical Therapeutic Chemical classification codes N05-N06) was estimated through survival analysis using a Cox proportional hazards model, with a hierarchical time-varying exposure, reporting hazard rate ratios (HRR) with 95% CIs. All outcomes were adjusted for age, sex, parental history of mental illness, Charlson Comorbidity Index, educational level, income, and job status.
    Results: A total of 526 749 individuals had positive test results for SARS-CoV-2 (50.2% men; mean [SD] age, 41.18 [17.06] years), while 3 124 933 had negative test results (50.6% women; mean [SD] age, 49.36 [19.00] years), and 501 110 had no tests performed (54.6% men; mean [SD] age, 60.71 [19.78] years). Follow-up time was 1.83 years for 93.4% of the population. The risk of mental disorders was increased in individuals with positive (HRR, 1.24 [95% CI, 1.17-1.31]) and negative (HRR, 1.42 [95% CI, 1.38-1.46]) test results for SARS-CoV-2 compared with those never tested. Compared with individuals with negative test results, the risk of new-onset mental disorders in SARS-CoV-2-positive individuals was lower in the group aged 18 to 29 years (HRR, 0.75 [95% CI, 0.69-0.81]), whereas individuals 70 years or older had an increased risk (HRR, 1.25 [95% CI, 1.05-1.50]). A similar pattern was seen regarding psychotropic medication use, with a decreased risk in the group aged 18 to 29 years (HRR, 0.81 [95% CI, 0.76-0.85]) and elevated risk in those 70 years or older (HRR, 1.57 [95% CI, 1.45-1.70]). The risk for new-onset mental disorders was substantially elevated in hospitalized patients with COVID-19 compared with the general population (HRR, 2.54 [95% CI, 2.06-3.14]); however, no significant difference in risk was seen when compared with hospitalization for non-COVID-19 respiratory tract infections (HRR, 1.03 [95% CI, 0.82-1.29]).
    Conclusion and relevance: In this Danish nationwide cohort study, overall risk of new-onset mental disorders in SARS-CoV-2-positive individuals did not exceed the risk among individuals with negative test results (except for those aged ≥70 years). However, when hospitalized, patients with COVID-19 had markedly increased risk compared with the general population, but comparable to risk among patients hospitalized for non-COVID-19 infections. Future studies should include even longer follow-up time and preferentially include immunological biomarkers to further investigate the impact of infection severity on postinfectious mental disorder sequelae.

    Abstract Background: The decision of whether to continue oral anticoagulation therapy (OAT) after successful surgical ablation of atrial fibrillation is challenging, and current guidelines provide no specific recommendations on whether or not it is safe to terminate OAT. Therefore, the aim of this study was to assess long-term outcomes in patients who either did or did not, receive OAT after surgical ablation of atrial fibrillation.
    Methods: In a prospective follow-up study, patients were included if surgical ablation of atrial fibrillation concomitantly with other cardiac surgery was done, between 2004 and 2018 at Aarhus University Hospital, Denmark. After 12 months, OAT was discontinued if: (a) sinus rhythm was documented by electrocardiogram, (b) atrial fibrillation was absent on 5-day Holter monitoring, (c) CHADS
    Results: A total of 560 patients underwent surgical ablation of which 436 patients reached the baseline at 12 months; 286 patients received OAT, and 150 had OAT discontinued. Survival analysis revealed no differences between the two groups (P = .723). Mean survival time in the group receiving OAT was 5.3 ± 3.3 years, compared to 5.1 ± 3.0 years in the group where OAT was discontinued (P = .784). There was no difference in major adverse cardiac and cerebrovascular events between the two groups (P = .846).
    Conclusion: Discontinuation of OAT is safe in patients with a CHADS

    Abstract Chronic wasting disease (CWD) is a prion disease affecting cervid species, both free-ranging and captive populations. As the geographic range continues to expand and disease prevalence continues to increase, CWD will have an impact on cervid populations, local economies, and ecosystem health. Mitigation of this "wicked" disease will require input from many different stakeholders including hunters, landowners, research biologists, wildlife managers, and others, working together. The NC1209 (North American interdisciplinary chronic wasting disease research consortium) is composed of scientists from different disciplines involved with investigating and managing CWD. Leveraging this broad breadth of expertise, the Consortium has created a state-of-the-science review of five key aspects of CWD, including current diagnostic capabilities for detecting prions, requirements for validating these diagnostics, the role of environmental transmission in CWD dynamics, and potential zoonotic risks associated with CWD. The goal of this review is to increase stakeholders', managers', and decision-makers' understanding of this disease informed by current scientific knowledge.

    Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder that primarily affects the elderly. An estimated 5.4 million people in the United States have AD, and its prevalence is expected to increase rapidly in the coming years. Few US Food and Drug Administration (FDA)-approved treatment options for AD are currently available. Donepezil is 1 of only 2 therapies approved in the United States for the treatment of moderate-to-severe AD. In 2010, the FDA approved a higher daily dose of donepezil (23 mg/day) for the treatment of AD in the moderate-to-severe stages based on positive results from a large, global, phase 3 clinical trial that compared switching to donepezil 23 mg/day with continuing treatment with donepezil 10 mg/day. In that trial, no benefit was seen in the co-primary endpoint of global functioning; however, donepezil 23 mg/day provided a small but significant improvement in the cognitive endpoint compared with donepezil 10 mg/day. A subgroup analysis subsequently showed that the cognitive benefits were significant irrespective of concomitant memantine use. Adverse events were mainly gastrointestinal related and were more prevalent in patients receiving the donepezil 23-mg/day dose during the first month of therapy, but were relatively infrequent thereafter. These data indicate that once-daily donepezil 23 mg may be an effective treatment option for patients with moderate-to-severe AD with or without concomitant memantine. This article reviews the rationale for using higher-dose donepezil, the clinical data supporting its use, and some of the practical implications that should be considered by practicing physicians when using donepezil 23 mg/day for patients with AD.

    Abstract A rich history of comparative research in the auditory field has afforded a synthetic view of sound information processing by ears and brains. Some organisms have proven to be powerful models for human hearing due to fundamental similarities (e.g., well-matched hearing ranges), while others feature intriguing differences (e.g., atympanic ears) that invite further study. Work across diverse "non-traditional" organisms, from small mammals to avians to amphibians and beyond, continues to propel auditory science forward, netting a variety of biomedical and technological advances along the way. In this brief review, limited primarily to tetrapod vertebrates, we discuss the continued importance of comparative studies in hearing research from the periphery to central nervous system with a focus on outstanding questions such as mechanisms for sound capture, peripheral and central processing of directional/spatial information, and non-canonical auditory processing, including efferent and hormonal effects.
