    Abstract Influenza virus infects millions of people annually and can cause global pandemics. Hemagglutinin (HA) is the primary component of commercial influenza vaccines (CIV), and antibody titer to HA is a primary correlate of protection. Continual antigenic variation of HA requires that CIVs are reformulated yearly. Structural organization of HA complexes have not previously been correlated with induction of broadly reactive antibodies, yet CIV formulations vary in how HA is organized. Using electron microscopy to study four current CIVs, we find structures including: individual HAs, starfish structures with up to 12 HA molecules, and novel spiked-nanodisc structures that display over 50 HA molecules along the complex's perimeter. CIV containing these spiked nanodiscs elicit the highest levels of heterosubtypic cross-reactive antibodies in female mice. Here, we report that HA structural organization can be an important CIV parameter and can be associated with the induction of cross-reactive antibodies to conserved HA epitopes.

    Abstract Three Odontaspis ferox (confirmed by mtDNA barcoding) were found in the English Channel and Celtic Sea in 2023 at Lepe, UK (50.7846, -1.3508), Kilmore Quay, Ireland (52.1714, -6.5937), and Lyme Bay, UK (50.6448, -2.9302). These are the first records of O. ferox in either country, and extend the species' range by over three degrees of latitude, to >52° N. They were ~275 (female), 433 (female), and 293 cm (male) total length, respectively. These continue a series of new records, possibly indicative of a climate change-induced shift in the species' range.

    Abstract Introduction: A comprehensive review of psychiatric pharmacy practice has never been performed in the United States. As psychiatric pharmacists become more involved in mental illness treatment, determining the current state of practice is important to help advance the specialty. The Professional Affairs Committee of the College of Psychiatric and Neurologic Pharmacists (CPNP) was charged with performing this review to define current psychiatric pharmacy practice.
    Methods: An electronic survey was sent to all pharmacist members of CPNP and all nonmember Board Certified Psychiatric Pharmacists (BCPPs) in the United States in late summer 2019. The survey consisted of 36 questions across multiple domains to obtain information about respondents' education and training background, practice setting and type, and information about prescriptive authority and other areas. An initial e-mail invitation was sent along with 2 reminder e-mails over the subsequent 2 weeks.
    Results: A total of 334 of 1015 pharmacists completed the survey (32.9%). Responders completed a postgraduate residency 77.8% of the time, and 88.3% were BCPP. Practice settings were split evenly between inpatient and outpatient practices or a combination of the 2. Among respondents, 46.5% reported having prescriptive authority as part of their practice, and 41.3% reported treating nonpsychiatric as well as psychiatric illnesses. Prescriptive authority was more likely in outpatient practices and in those treating nonpsychiatric illnesses.
    Discussion: The current practice of psychiatric pharmacy is incredibly varied in terms of practice setting, activities performed, and services provided. Further exploration is needed to help determine the optimal role of psychiatric pharmacists.

    Abstract Purpose: To identify the practice patterns related to use of surveillance mammography in male breast cancer (MaBC) survivors.
    Methods: Using administrative claims data from OptumLabs Data Warehouse, we identified men who underwent surgery for breast cancer during 2007-2017. We calculated the proportion of men who had at least one mammogram (a) within 13 months for all patients and (b) within 24 months amongst those who maintained their insurance coverage for at least that length of time after surgery. Multivariate logistic regression modeling was used to identify factors associated with mammography within each timeframe.
    Results: Out of 729 total MaBC survivors, 209 (29%) underwent mammography within 13 months after surgery. Among those who had lumpectomy, 41% underwent mammography, whereas among those who had mastectomy, 27% had mammography. Amongst 526 men who maintained consistent insurance coverage for 24 months after surgery, 215 (41%) underwent mammography at least once during that 24-month period. In this cohort, the proportion who had at least one mammogram during the 24-month period was 49% after lumpectomy and 40% after mastectomy. In a multivariate logistic regression model, more recent diagnosis (2015+) and older age at diagnosis were associated with lower odds of undergoing mammography, while receipt of radiation was associated with higher odds of undergoing mammography.
    Conclusions: Although recent ASCO guidelines recommend surveillance mammography after lumpectomy, a minority of MaBC survivors undergo surveillance mammography, even after lumpectomy. This is likely due to the paucity of data regarding the true benefits and harms of surveillance/screening mammography for MaBC.

    Abstract Objective: This paper presents and evaluates a breast-specific magnetic resonance guided focused ultrasound (MRgFUS) system. A first-in-human evaluation demonstrates the novel hardware, a sophisticated tumor targeting algorithm and a volumetric magnetic resonance imaging (MRI) protocol.
    Methods: At the time of submission, N = 10 patients with non-palpable T0 stage breast cancer have been treated with the breast MRgFUS system. The described tumor targeting algorithm is evaluated both with a phantom test and in vivo during the breast MRgFUS treatments. Treatments were planned and monitored using volumetric MR-acoustic radiation force imaging (MR-ARFI) and temperature imaging (MRTI).
    Results: Successful technical treatments were achieved in 80 % of the patients. All patients underwent the treatment with no sedation and 60 % of participants had analgesic support. The total MR treatment time ranged from 73 to 114 minutes. Mean error between desired and achieved targeting in a phantom was 2.9 ±1.8 mm while 6.2 ±1.9 mm was achieved in patient studies, assessed either with MRTI or MR-ARFI measurements. MRTI and MR-ARFI were successful in 60 % and 70 % of patients, respectively.
    Conclusion: The targeting accuracy allows the accurate placement of the focal spot using electronic steering capabilities of the transducer. The use of both volumetric MRTI and MR-ARFI provides complementary treatment planning and monitoring information during the treatment, allowing the treatment of all breast anatomies, including homogeneously fatty breasts.

    Abstract Background: Rescue of mitochondrial function is a promising neuroprotective strategy for Parkinson's disease (PD). Ursodeoxycholic acid (UDCA) has shown considerable promise as a mitochondrial rescue agent across a range of preclinical in vitro and in vivo models of PD.
    Objectives: To investigate the safety and tolerability of high-dose UDCA in PD and determine midbrain target engagement.
    Methods: The UP (UDCA in PD) study was a phase II, randomized, double-blind, placebo-controlled trial of UDCA (30 mg/kg daily, 2:1 randomization UDCA vs. placebo) in 30 participants with PD for 48 weeks. The primary outcome was safety and tolerability. Secondary outcomes included 31-phosphorus magnetic resonance spectroscopy (
    Results: UDCA was safe and well tolerated, and only mild transient gastrointestinal adverse events were more frequent in the UDCA treatment group. Midbrain
    Conclusions: High-dose UDCA is safe and well tolerated in early PD. Larger trials are needed to further evaluate the disease-modifying effect of UDCA in PD. © 2023 The Authors.

    Abstract Purpose: The Review Committee for Surgery requires a minimum program director (PD) tenure of 6 years. The impact of PD turnover on the performance of program graduates is unknown. We hypothesize that (1) the majority of PDs step down before 6-year tenure and (2) higher PD turnover is associated with higher failure rate on American Board of Surgery (ABS) examinations.
    Methods: Start and stop dates of all surgery PDs between January 1, 2000 and December 31, 2017 were obtained for civilian surgery programs. A Kaplan-Meier curve of PD "survival" was constructed. Programs were divided into High Turnover (HT; ≥4 PD changes, n = 33) and Low Turnover (LT; ≤3 PD changes, n = 191) groups. Five-year (2013-2017) ABS pass rates were also obtained. Pass rates and compliance with current standards were compared between groups.
    Results: Kaplan-Meier analysis revealed that 40% of PDs do not comply with ACGME policy and serve <6 years. HT programs had lower mean pass rates on ABS certifying exam than LT programs (76% vs 83%, p < 0.01), but not qualifying exam (88% vs 88%). HT programs are less likely to meet the current 65% pass rate standard (82% vs 93%, p < 0.05).
    Conclusions: (1) An estimated 40% of general surgery PDs had tenures of <6 years. (2) Greater PD turnover is associated with lower ABS pass rates among general surgery graduates.

    Abstract Background: The scale of the 2022 global mpox (formerly known as monkeypox) outbreak has been unprecedented. In less than 6 months, non-endemic countries have reported more than 67 000 cases of a disease that had previously been rare outside of Africa. Mortality has been reported as rare but hospital admission has been relatively common. We aimed to describe the clinical and laboratory characteristics and outcomes of individuals admitted to hospital with mpox and associated complications, including tecovirimat recipients.
    Methods: In this cohort study, we undertook retrospective review of electronic clinical records and pathology data for all individuals admitted between May 6, and Aug 3, 2022, to 16 hospitals from the Specialist and High Consequence Infectious Diseases Network for Monkeypox. The hospitals were located in ten cities in England and Northern Ireland. Inclusion criteria were clinical signs consistent with mpox and MPXV DNA detected from at least one clinical sample by PCR testing. Patients admitted solely for isolation purposes were excluded from the study. Key outcomes included admission indication, complications (including pain, secondary infection, and mortality) and use of antibiotic and anti-viral treatments. Routine biochemistry, haematology, microbiology, and virology data were also collected. Outcomes were assessed in all patients with available data.
    Findings: 156 individuals were admitted to hospital with complicated mpox during the study period. 153 (98%) were male and three (2%) were female, with a median age of 35 years (IQR 30-44). Gender data were collected from electronic patient records, which encompassed full formal review of clincian notes. The prespecified options for data collection for gender were male, female, trans, non-binary, or unknown. 105 (71%) of 148 participants with available ethnicity data were of White ethnicity and 47 (30%) of 155 were living with HIV with a median CD4 count of 510 cells per mm
    Interpretation: Although life-threatening mpox appears rare in hospitalised populations during the current outbreak, severe mpox and associated complications can occur in immunocompetent individuals. Analgesia and management of superimposed bacterial infection are priorities for patients admitted to hospital.
    Funding: None.
