Real word outcomes of cabozantinib therapy in poorly differentiated thyroid carcinoma.

Objective: Poorly differentiated thyroid carcinomas (PDTCs) are rare and aggressive head and neck malignancies with a poor prognosis. Systemic treatment for incurable PDTC consists of multi-kinase inhibitors (MKIs) based on extrapolation from the experience with radioiodine refractory differentiated thyroid cancer (DTC). Cabozantinib is an approved second-line MKI therapy for DTC, but there are limited data regarding the safety and efficacy of cabozantinib for PDTC.

Single-Institution Experience of Larotrectinib Therapy for Patients With Fusion-Positive Thyroid Carcinoma.

Context: The real world efficacy and tolerabiltiy of NTRK inhibitor larotrectinib has not yet been reported in the literature although trial data has shown promising results.

Objective: We report a retrospective analysis of patients with thyroid cancer harboring fusions who underwent treatment with larotrectinib.

Methods: A single-institution, retrospective case series of patients with fusion-positive thyroid cancers treated with neurotrophic tyrosine receptor kinase ( inhibitors from January 1, 2007, to January 1, 2023, was performed.

Biomechanical adaptations enable phoretic mite species to occupy distinct spatial niches on host burying beetles.

Niche theory predicts that ecologically similar species coexist by minimizing interspecific competition through niche partitioning. Therefore, understanding the mechanisms of niche partitioning is essential for predicting interactions and coexistence between competing organisms. Here, we study two phoretic mite species, and that coexist on the same host burying beetle and use it to 'hitchhike' between reproductive sites.

The impact of the COVID-19 pandemic on cardiovascular disease prevention and corresponding geographical inequalities in England: interrupted time series analysis.

Background: There has been disruption to the detection and management of those with hypertension and atrial fibrillation (AF) during the COVID-19 pandemic. This is likely to vary geographically and could have implications for future mortality and morbidity. We aimed to estimate the change in diagnosed prevalence, treatment and prescription indicators for AF and hypertension and assess corresponding geographical inequalities.

Association of a calcium channel blocker and diuretic prescribing cascade with adverse events: A population-based cohort study.

Background: Prescribing cascades occur when a drug adverse event is misinterpreted as a new medical condition and a second, potentially unnecessary drug, is prescribed to treat the adverse event. The population-level consequences of prescribing cascades remain unknown.

Methods: This population-based cohort study used linked health administrative databases in Ontario, Canada.

Acute presentations of eating disorders among adolescents and adults before and during the COVID-19 pandemic in Ontario, Canada.

Background: Increased rates of pediatric eating disorders have been observed during the COVID-19 pandemic, but little is known about trends among adults. We aimed to evaluate rates of emergency department visits and hospital admissions for eating disorders among adolescents and adults during the pandemic.

Methods: We conducted a population-based, repeated cross-sectional study using linked health administrative data for Ontario residents aged 10-105 years during the prepandemic (Jan.

External validation of the first prognostic nomogram for older adults with cancer.

Background: The geriatric oncology population tends to be complex because of multimorbidity, functional and cognitive decline, malnutrition and social frailty. Prognostic indices for predicting survival of elderly cancer patients to guide treatment remain scarce. A nomogram based on all domains of the geriatric assessment was previously developed at the National Cancer Centre Singapore (NCCS) to predict overall survival (OS) in elderly cancer patients.

Whole-brain mapping of long-range inputs to the VIP-expressing inhibitory neurons in the primary motor cortex.

The primary motor cortex (MOp) is an important site for motor skill learning. Interestingly, neurons in MOp possess reward-related activity, presumably to facilitate reward-based motor learning. While pyramidal neurons (PNs) and different subtypes of GABAergic inhibitory interneurons (INs) in MOp all undergo cell-type specific plastic changes during motor learning, the vasoactive intestinal peptide-expressing inhibitory interneurons (VIP-INs) in MOp have been shown to preferentially respond to reward and play a critical role in the early phases of motor learning by triggering local circuit plasticity.

Brief Report: High Levels of CD47 Expression in Thymic Epithelial Tumors.

Introduction: CD47 is a tumor antigen that inhibits phagocytosis leading to immune evasion. Anti-CD47 therapy is a promising new immunotherapy across numerous tumor types, but it has not been tested in thymic epithelial tumors (TETs): thymomas and thymic carcinomas. TETs are rare tumors that are difficult to treat, especially with programmed cell death protein 1/programmed death-ligand 1 checkpoint inhibitors, owing to the excessive rates of immune-related adverse events.

Risk of interpersonal violence during and after pregnancy among people with schizophrenia: a population-based cohort study.

Background: Schizophrenia is associated with increased risk of experiencing interpersonal violence. Little is known about risk specifically around the time of pregnancy.

Methods: This population-based cohort study included all individuals (aged 15-49 yr) listed as female on their health cards who had a singleton birth in Ontario, Canada, between 2004 and 2018.

Preventive Health Care Among Children of Women With Schizophrenia: A Population-Based Cohort Study.

To compare well-baby visit and vaccination schedule adherence up to age 24 months in children of mothers with versus without schizophrenia. Using administrative health data on births in Ontario, Canada (2012-2016), children of mothers with schizophrenia (: 295; : F20/F25; schizophrenia or schizoaffective disorder) (n = 1,275) were compared to children without maternal schizophrenia (n = 520,831) on (1) well-baby visit attendance, including an enhanced well-baby visit at age 18 months, and (2) vaccine schedule adherence for diphtheria, tetanus, pertussis, polio, type B (DTaP-IPV-Hib), and measles, mumps, rubella (MMR). Cox proportional hazard regression models were adjusted for each of maternal sociodemographics, maternal health, and child health characteristics in blocks and all together in a fully adjusted model.

Toward a mechanically biocompatible intervertebral disc: Engineering of combined biomimetic annulus fibrosus and nucleus pulposus analogs.

Intervertebral disc (IVD) degeneration and accompanying lower back pain impose global medical and societal challenges, affecting over 600 million people worldwide. The IVD complex fibrocartilaginous structure is responsible for the spine biomechanical function. The nucleus pulposus (NP), composed of swellable glycosaminoglycan (GAG), transfers compressive loads to the surrounding fiber-reinforced annulus fibrosus (AF) lamellae, which stretches under tension.

Disability and in-hospital breastfeeding practices and supports in Ontario, Canada: a population-based study.

Background: Breastfeeding provides infants with nutrients required for optimal growth and development. We aimed to examine breastfeeding practices and supports that promote exclusive breastfeeding during the birth hospital stay among birthing parents with physical disabilities, sensory disabilities, intellectual or developmental disabilities, and multiple disabilities compared with those without a disability.

Methods: This population-based cohort study was done in Ontario, Canada.

Determinants of Hospital Use and Physician Services Among Adults With a History of Homelessness.

Background: People experiencing homelessness have diverse patterns of healthcare use. This study examined the distribution and determinants of healthcare encounters among adults with a history of homelessness.

Methods: Administrative healthcare records were linked with survey data for a general cohort of adults with a history of homelessness and a cohort of homeless adults with mental illness.

Disability and Interpersonal Violence in the Perinatal Period.

Objective: To compare the risk of interpersonal violence experienced by pregnant and postpartum individuals with physical disabilities, sensory disabilities, or intellectual or developmental disabilities with those without disabilities, and to examine whether a prepregnancy history of interpersonal violence puts individuals with disabilities, at excess risk of interpersonal violence in the perinatal period.

Method: This population-based study included all individuals aged 15-49 years with births in Ontario, Canada, from 2004 to 2019. Individuals with physical (n=147,414), sensory (n=47,459), intellectual or developmental (n=2,557), or multiple disabilities (n=9,598) were compared with 1,594,441 individuals without disabilities.

Towards Accurate Reconstruction of 3D Scene Shape From A Single Monocular Image.

Despite significant progress made in the past few years, challenges remain for depth estimation using a single monocular image. First, it is nontrivial to train a metric-depth prediction model that can generalize well to diverse scenes mainly due to limited training data. Thus, researchers have built large-scale relative depth datasets that are much easier to collect.

Functionally distinct NPAS4-expressing somatostatin interneuron ensembles critical for motor skill learning.

During motor learning, dendritic spines on pyramidal neurons (PNs) in the primary motor cortex (M1) undergo reorganization. Intriguingly, the inhibition from local somatostatin-expressing inhibitory neurons (SST-INs) plays an important role in regulating the PN plasticity and thus new motor skill acquisition. However, the molecular mechanisms underlying this process remain unclear.

How Getting Friendly with Bacteria Can Promote Student Appreciation of Microbial Diversity and Their Civic Scientific Literacy.

ePortfolios are digital repositories where students can curate papers, projects, and reflections from individual or multiple courses across the disciplines and in a variety of formats to showcase their learning. This transparent and portable medium, which enables students to document their knowledge and abilities for assessment and career development, has been recognized by the American Association of Colleges and Universities as one of 11 high-impact practices. Using tailored rubrics, student assessment of learning gain surveys, and end-of-course exam questions, this study demonstrates how an ePortfolio assignment can be used in microbiology courses taken by majors and nonmajors to measure student learning outcomes in several course and program learning goals.

Perinatal mental illness among women with disabilities: a population-based cohort study.

Purpose: To examine the risk of perinatal mental illness, including new-onset disorders and recurrent or ongoing use of mental health care, comparing women with physical, sensory, intellectual/developmental, and multiple disabilities to those without a disability.

Methods: From all women aged 15-49 years with a singleton birth in Ontario, Canada (2003-2018), those with physical (n = 144,972), sensory (n = 45,249), intellectual/developmental (n = 2,227), and ≥ 2 of these disabilities ("multiple disabilities"; n = 8,883), were compared to 1,601,363 without a disability on risk of healthcare system contact for mental illness from conception to 365 days postpartum. The cohort was stratified into: (1) no pre-pregnancy mental illness (to identify new-onset illness), (2) distal mental illness (> 2 years pre-pregnancy, to identify recurrent illness), and (3) recent mental illness (0-2 years pre-pregnancy, to identify ongoing contact).
