A faunal inventory of methane seeps on the Pacific margin of Costa Rica.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography. During five expeditions between 2009 and 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths of 300-3600 m. Based on these expeditions and published literature, we compiled voucher specimens, images, and 274 newly published DNA sequences to present a taxonomic inventory of macrofaunal and megafaunal diversity with a focus on invertebrates.

IQ Survey Results on Current Industry Practices-Part 1: Immunogenicity Risk Assessment.

An immunogenicity risk assessment (IRA) is a relatively new expectation of health authorities that is increasingly incorporated into the drug development process across the pharmaceutical/biotech industry. The guiding principle for an IRA includes a comprehensive evaluation of product- and patient-related factors that may influence the immunogenic potential of a biotherapeutic drug and a potential action plan. The Immunogenicity Working Group from the IQ Consortium (Clinical Pharmacology Leadership Group) has conducted a survey to understand the current practices for conducting IRAs and relevant aspects of bioanalysis.

Submucosal Microbiome Profiles in Paired and Unpaired Samples From Healthy and Peri-Implantitis Dental Implants.

Background: This cross-sectional study aimed to compare the composition of the submucosal microbiome of peri-implantitis with paired and unpaired healthy implant samples.

Methods: We evaluated submucosal plaque samples obtained in 39 cases, including 13 cases of peri-implantitis, 13 cases involving healthy implants from the same patient (paired samples), and 13 cases involving healthy implants from different individuals (unpaired samples). The patients were evaluated using next-generation genomic sequencing (Illumina) based on 16S rRNA gene amplification.

Integrated Longitudinal Population Dose-Hemoglobin Response of Daprodustat Following Dose Titration in Patients With Anemia in Chronic Kidney Disease.

Daprodustat, a novel oral hypoxia-inducible factor prolyl hydroxylase inhibitor is approved in the United States for the treatment of anemia due to chronic kidney disease (CKD) in adults receiving dialysis for at least 4 months. Pharmacodynamic dose-hemoglobin (Dose-Hgb) models were developed as daprodustat progressed through development. To support global phase III development, a dose-titration algorithm, guided by simulations from the initial Dose-Hgb model based on phase II clinical data, was implemented.

Practical management of adverse events in patients receiving tarlatamab, a delta-like ligand 3-targeted bispecific T-cell engager immunotherapy, for previously treated small cell lung cancer.

Tarlatamab is a bispecific T-cell engager immunotherapy targeting delta-like ligand 3 (DLL3) and the cluster of differentiation 3 (CD3) molecule. In the phase 2 DeLLphi-301 trial of tarlatamab for patients with previously treated small cell lung cancer, tarlatamab 10 mg every 2 weeks achieved durable responses and encouraging survival outcomes. Analyses of updated safety data from the DeLLphi-301 trial demonstrated that the most common treatment-emergent adverse events were cytokine release syndrome (53%), pyrexia (38%), decreased appetite (36%), dysgeusia (32%), and an emia (30%).

Descriptive Epidemiology of Complete ACL Tears in the Skeletally Immature Population: A Prospective Multicenter PLUTO Study.

Background: Anterior cruciate ligament (ACL) injuries are common in pediatric and adolescent patients. Understanding this population's injury characteristics and treatment strategies is vital for managing this high-risk group.

Purpose: To report the descriptive epidemiology and treatment strategies of a large cohort of skeletally immature patients with complete ACL tears.

Mental health literacy among primary care providers in Hungary: a vignette-based survey.

Objective: This study examined mental health literacy and predictors of disorder recognition among primary care providers (PCPs) in Hungary.

Methods: 208 PCPs in Hungary completed a survey assessing demographics, mental health stigma, and exposure to mental health (i.e.

Polygenic burden of short tandem repeat expansions promotes risk for Alzheimer's disease.

Studies of the genetics of Alzheimer's disease (AD) have largely focused on single nucleotide variants and short insertions/deletions. However, most of the disease heritability has yet to be uncovered, suggesting that there is substantial genetic risk conferred by other forms of genetic variation. There are over one million short tandem repeats (STRs) in the genome, and their link to AD risk has not been assessed.

Evaluation of HER2-Low breast carcinoma in metastatic settings: a cytological approach to proliferation and survival.

Introduction: Human epidermal growth factor receptor 2 (HER2)-low breast cancer, defined by HER2 immunohistochemistry scores of 1+ or 2+ without gene amplification, represents a unique subgroup with emerging therapeutic implications. Limited data describe the behavior of HER2-low tumors, particularly in metastatic settings. This study evaluated the frequency of HER2-low expression, Ki-67 proliferation index, and survival outcomes across HER2 subtypes in metastatic breast carcinoma using cytology specimens.

Incidentally discovered inflammatory pseudotumour of the spleen: understanding clinical manifestations and diagnosis.

A splenic inflammatory pseudotumour (IPT) is a rare condition in which inflammatory cells and non-cancerous specialised cells known as myofibroblasts abnormally replicate in the spleen. Patients with IPT may experience symptoms like abdominal pain, fever and weight loss, making it difficult to distinguish from processes like cancer. As a result, diagnosing IPT often requires imaging studies and microscopic examination.

Ultrasound-triggered release of vancomycin from a novel spinal device: Antibiotic release and efficacy in vivo.

Post-surgical spinal infection occurs in up to 20% of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm) were 3D-printed with an interior reservoir (0.

The long-term effects of housing insecurity in young adulthood on subsequent material hardship, physiological and mental health.

Economic and material hardship, including housing insecurity - limited or uncertain availability or access to safe, quality, and affordable housing - is strongly linked to negative physical and mental health outcomes among adolescents and adults. However, data limitations and the inherent selectivity of housing insecurity have hindered comprehensive analysis of its long-term effects on physiological and mental health. This study uses data from The National Longitudinal Study of Adolescent to Adult Health (Add Health) to construct a sample of participants who experienced housing insecurity between the ages of 18-26 (Wave III) to a suitable control group using propensity score matching.

Retrospective cohort study of trends in the use of outpatient parathyroidectomy by surgical indication.

Background: A shift toward outpatient parathyroidectomy was seen in the early 2000s. Recent trends, especially for secondary and tertiary hyperparathyroidism, have not been described. This study evaluates temporal trends in same-day, overnight, and inpatient parathyroidectomy by surgical indication.

Thyroid Nodules with Indeterminate Cytology and Negative Molecular Profile: Prevalence of Malignancy and Practice Paradigms for Surveillance.

In the era of molecular testing, thyroid nodules with indeterminate cytology are increasingly being managed nonoperatively. The false-negative rates of these molecular tests, and therefore missed malignancies, are not well defined in real-world clinical practice. This retrospective study of patients undergoing fine needle aspiration (FNA) biopsy at our health system between November 2017 and March 2022 included nodules with The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) III and IV cytology and negative, currently negative, or negative but limited ThyroSeq version 3 (TSv3) results.

Hepatosplenic T-cell lymphoma in children and adolescents.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Difficulty With Board Certification in Urology Is Associated With Adverse Medical License Actions.

Introduction: Board certification in urology is a multistep process including a written qualifying examination (QE), followed by an oral certifying examination (CE) approximately 2 years after residency or fellowship completion. The goal of this process is to ensure that urologists are well trained, have an extensive fund of knowledge, demonstrate professionalism and competence in practice, and are safe to practice urology. Board certification in urology serves to both establish and confirm physician competence and ultimately protect the public.

Multidimensional scaling improves distance-based clustering for microbiome data.

Motivation: Clustering patients into subgroups based on their microbial compositions can greatly enhance our understanding of the role of microbes in human health and disease etiology. Distance-based clustering methods, such as partitioning around medoids (PAM), are popular due to their computational efficiency and absence of distributional assumptions. However, the performance of these methods can be suboptimal when true cluster memberships are driven by differences in the abundance of only a few microbes, a situation known as the sparse signal scenario.
