The Calicophoron daubneyi genome provides new insight into mechanisms of feeding, eggshell synthesis and parasite-microbe interactions.

Background: The rumen fluke, Calicophoron daubneyi, is the major paramphistome species infecting ruminants within Europe. Adult flukes reside within the rumen where they are in direct contact with a unique collection of microorganisms. Here, we report a 1.

AUGMENTed Real-World Data Enhances Comparative Efficacy Between Once-Weekly Insulin Icodec with Dosing Guide App Versus Once-Daily Insulin Glargine U300 in Insulin-Naive Type 2 Diabetes.

Introduction: ONWARDS 5 evaluated the effectiveness and safety of insulin icodec (icodec) titrated with a dosing guide app (icodec with app) versus once-daily insulin analogs in insulin-naive adults with type 2 diabetes. The insulin glargine U300 (glargine U300) stratum was too small to enable a robust post hoc efficacy comparison. Augmentation methodology was applied to increase the glargine U300 group size using real-world data (RWD), to facilitate efficacy comparisons of icodec with app versus glargine U300, and to demonstrate the potential of the augmentation methodology to strengthen underpowered treatment comparisons (AUGMENT study).

Measuring hospital inpatient Procedure Access Inequality in the United States.

Geographic disparities in access to inpatient procedures are a significant issue within the US healthcare system. This study introduces the Procedure Access Inequality (PAI) index, a standardized metric to quantify these disparities while adjusting for disease prevalence. Using data from the Healthcare Cost and Utilization Project State Inpatient Databases, we analyzed inpatient procedure data from 18 states between 2016 and 2019.

Machine Learning Identification of Modifiable Predictors of Patient Outcomes After Transcatheter Aortic Valve Replacement.

Background: Transcatheter aortic valve replacement (TAVR) is an important treatment option for patients with severe symptomatic aortic stenosis. It is important to identify predictors of excellent outcomes (good clinical outcomes, more time spent at home) after TAVR that are potentially amenable to improvement.

Objectives: The purpose of the study was to use machine learning to identify potentially modifiable predictors of clinically relevant patient-centered outcomes after TAVR.

Rac1 and Nectin3 are essential for PCP-directed axon guidance in the peripheral auditory system.

Our sense of hearing is critically dependent on the spiral ganglion neurons (SGNs) that connect the sound receptors in the organ of Corti (OC) to the cochlear nuclei of the hindbrain. Type I SGNs innervate inner hair cells (IHCs) to transmit sound signals, while type II SGNs (SGNIIs) innervate outer hair cells (OHCs) to detect moderate-to-intense sound. During development, SGNII afferents make a characteristic 90-degree turn toward the base of the cochlea and innervate multiple OHCs.

Limited Access to Aortic Valve Procedures in Socioeconomically Disadvantaged Areas.

Background: To explore how differences in local socioeconomic deprivation impact access to aortic valve procedures and the treatment of aortic valve disease, in comparison to other open and minimally invasive surgical procedures.

Methods And Results: Procedure volume data were obtained from the Healthcare Cost and Utilization Project from 18 states from 2016 to 2019 and merged with area deprivation index data, an index of zip code-level socioeconomic distress. We estimate the relationship between local deprivation ranking and differences in volumes of aortic valve replacement, which include transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR), versus coronary artery bypass graft surgery and laparoscopic colectomy (LC).

Tertiary lymphoid structures sustain cutaneous B cell activity in hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic skin condition affecting approximately 1% of the US population. HS skin lesions are highly inflammatory and characterized by a large immune infiltrate. While B cells and plasma cells comprise a major component of this immune milieu, the biology and the contribution of these cells in HS pathogenesis are unclear.

Long-term risk of reintervention after transcatheter aortic valve replacement.

Background: Transcatheter aortic valve replacement (TAVR) has surpassed surgical aortic valve replacement (SAVR) as the predominant mode of valve replacement for the treatment of severe aortic stenosis (AS). However, the long-term need for valvular reintervention after TAVR remains unknown.

Methods: Using data from the Medicare Fee for Service 100% dataset, all patients receiving TAVR between July 2011 and December 2020 were identified.

Development of an amplicon-based sequencing approach in response to the global emergence of mpox.

The 2022 multicountry mpox outbreak concurrent with the ongoing Coronavirus Disease 2019 (COVID-19) pandemic further highlighted the need for genomic surveillance and rapid pathogen whole-genome sequencing. While metagenomic sequencing approaches have been used to sequence many of the early mpox infections, these methods are resource intensive and require samples with high viral DNA concentrations. Given the atypical clinical presentation of cases associated with the outbreak and uncertainty regarding viral load across both the course of infection and anatomical body sites, there was an urgent need for a more sensitive and broadly applicable sequencing approach.

Methods: We conducted a cross-sectional survey on the mental health and financial burden of caregivers of CMC from April 2020 to April 2021. The study sample included 70 caregivers.

Tertiary Lymphoid Structures Sustain Cutaneous B cell Activity in Hidradenitis Suppurativa.

Background: Hidradenitis suppurativa (HS) skin lesions are highly inflammatory and characterized by a large immune infiltrate. While B cells and plasma cells comprise a major component of this immune milieu the biology and contribution of these cells in HS pathogenesis is unclear.

Objective: We aimed to investigate the dynamics and microenvironmental interactions of B cells within cutaneous HS lesions.

Cost-utility and cost-benefit analysis of TAVR availability in the US severe symptomatic aortic stenosis patient population.

Aims: We evaluated the availability of transcatheter aortic valve replacement (TAVR) to determine its value across all severe symptomatic aortic stenosis (SSAS) patients, especially those untreated because of concerns regarding invasive surgical AVR (SAVR) and its impact on active aging.

Methods: We performed payer perspective cost-utility analysis (CUA) and societal perspective cost-benefit analysis (CBA). The CBA's benefit measure is active time: salaried labor, unpaid work, and active leisure.

Measuring irritability in young adults: An integrative review of measures and their psychometric properties.

WHAT IS KNOWN ON THE SUBJECT?: Irritability is a transdiagnostic psychiatric symptom among different mental health diagnoses, such as depression, anxiety, personality and substance abuse disorders. Despite the prevalence of irritability across various psychiatric disorders, there is a lack of assessment measures developed and validated to specifically assess irritability. Existing evidence suggests that young adults with depression combined with irritability experience higher disease burden compared with depressed peers with low levels of irritability.

Which Factors Are Important to Women When Choosing a Breast Reconstruction Surgeon?

Background: Women undergoing breast reconstruction often research their health care provider options. The authors studied which factors may influence how a woman selects a plastic surgeon for breast reconstruction surgery.

Methods: An online survey was distributed by means of Amazon Mechanical Turk (MTurk; Amazon Web Services, Inc.

The unintended consequences of Medicare's wage index adjustment on device-intensive hospital procedures.

Objectives: To study the association between Medicare's wage index adjustment and the differential use of labor-intensive surgical procedures and medical device-intensive minimally invasive clinical procedures across the United States.

Study Design: We combine a conceptual model and an empirical investigation of its predictions, applied to aortic valve replacement, to study the relationship between variation in Medicare wage index payment adjustment across hospital referral regions (HRRs) and the utilization of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in these areas.

Methods: Using detailed individual Medicare claims data for 2013-2018 and a novel geographical crosswalk to nest information on Medicare's wage index and utilization of TAVR and SAVR, we estimate a mixed effects Poisson regression model across HRRs to test our hypotheses.

A Comparison of Complications in Therapeutic versus Contralateral Prophylactic Mastectomy Reconstruction: A Paired Analysis.

Background: Although breast reconstruction after bilateral mastectomies including a contralateral prophylactic mastectomy is known to have a higher overall complication profile, whether reconstructive complication rates differ between the therapeutic mastectomy and contralateral prophylactic mastectomy sides remains unclear.

Methods: Women undergoing bilateral mastectomies with autologous or implant-based breast reconstruction for a unilateral breast cancer at a single institution were identified (2009 to 2019). Postoperative complications were stratified by laterality (therapeutic mastectomy versus contralateral prophylactic mastectomy).

Contemporary Costs Associated With Transcatheter Versus Surgical Aortic Valve Replacement in Medicare Beneficiaries.

Background: In patients with severe aortic stenosis, treatment with transcatheter aortic valve replacement (TAVR) has been shown to be cost-effective in the high-risk surgical population and cost-saving in the intermediate-risk population when compared with surgical aortic valve replacement (SAVR) in early pivotal clinical trials. Whether TAVR is associated with comparable or lower costs when compared with SAVR in contemporary clinical practice is unknown.

Methods: Using data from the Medicare Dataset Standard Analytic Files 5% Fee for Service database, patients receiving either TAVR or SAVR between 2016 and 2018 were identified.

Transmission from vaccinated individuals in a large SARS-CoV-2 Delta variant outbreak.

An outbreak of over 1,000 COVID-19 cases in Provincetown, Massachusetts (MA), in July 2021-the first large outbreak mostly in vaccinated individuals in the US-prompted a comprehensive public health response, motivating changes to national masking recommendations and raising questions about infection and transmission among vaccinated individuals. To address these questions, we combined viral genomic and epidemiological data from 467 individuals, including 40% of outbreak-associated cases. The Delta variant accounted for 99% of cases in this dataset; it was introduced from at least 40 sources, but 83% of cases derived from a single source, likely through transmission across multiple settings over a short time rather than a single event.

Triceps Rupture and Repair in a Healthy, Young Woman following Rock Climbing.

Triceps tendon rupture in females is rare. In this case report, we present a young adult female patient with a distal triceps tendon rupture from bouldering treated with open surgical repair technique using a modified bone tunnel and suture anchor fixation technique. The diagnosis and technique for repair and postoperative rehabilitation are described.

Early-life inflammation primes a T helper 2 cell-fibroblast niche in skin.

Inflammation early in life can prime the local immune milieu of peripheral tissues, which can cause lasting changes in immunological tone that confer disease protection or susceptibility. The cellular and molecular mechanisms that prompt changes in immune tone in many nonlymphoid tissues remain largely unknown. Here we find that time-limited neonatal inflammation induced by a transient reduction in neonatal regulatory T cells causes a dysregulation of subcutaneous tissue in mouse skin.

Evidence of transmission from fully vaccinated individuals in a large outbreak of the SARS-CoV-2 Delta variant in Provincetown, Massachusetts.

Multiple summer events, including large indoor gatherings, in Provincetown, Massachusetts (MA), in July 2021 contributed to an outbreak of over one thousand COVID-19 cases among residents and visitors. Most cases were fully vaccinated, many of whom were also symptomatic, prompting a comprehensive public health response, motivating changes to national masking recommendations, and raising questions about infection and transmission among vaccinated individuals. To characterize the outbreak and the viral population underlying it, we combined genomic and epidemiological data from 467 individuals, including 40% of known outbreak-associated cases.
