Intratumoral heterogeneity of oncogenic drivers in mixed histology lung adenocarcinomas: How tissue selection impacts molecular testing?

Majority of the lung adenocarcinomas show a mixture of different histological patterns. The possibility of histologically heterogeneous areas of the adenocarcinoma showing genetic heterogeneity and harboring different driver mutations, with potentially significant clinical impact, has not been adequately addressed. Currently, there are no guidelines to suggest how to submit tumor tissue in adenocarcinomas with mixed histological features for molecular testing.

The association of outdoor temperature and self-reported Raynaud's phenomenon severity among people with systemic sclerosis: a Scleroderma Patient-centered Intervention Network Cohort study.

Background: Raynaud's phenomenon is the earliest and most common systemic sclerosis manifestation. Episodes can be triggered by cold exposure and ambient temperature changes. Small studies have found that Raynaud's phenomenon outcomes were associated with season.

Minimal Detectable Changes of the Health Assessment Questionnaire-Disability Index, Patient-Reported Outcomes Measurement Information System-29 Profile Version 2.0 Domains, and Patient Health Questionnaire-8 in People With Systemic Sclerosis: A Scleroderma Patient-Centered Intervention Network Cohort Cross-Sectional Study.

Objective: Systemic sclerosis (SSc) is a rare, chronic autoimmune disorder associated with disability, diminished physical function, fatigue, pain, and mental health concerns. We assessed minimal detectable changes (MDCs) of the Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient-Reported Outcomes Measurement Information System-29 Profile version 2.0 (PROMIS-29v2.

The association of resilience and positive mental health in systemic sclerosis: A Scleroderma Patient-centered Intervention Network (SPIN) cohort cross-sectional study.

Objective: A previous study using Scleroderma Patient-centered Intervention Network (SPIN) Cohort data identified five classes of people with systemic sclerosis (also known as scleroderma) based on patient-reported somatic (fatigue, pain, sleep) and mental health (anxiety, depression) symptoms and compared indicators of disease severity between classes. Across four classes ("low", "normal", "high", "very high"), there were progressively worse somatic and mental health outcomes and greater disease severity. The fifth ("high/low") class, however, was characterized by high disease severity, fatigue, pain, and sleep but low mental health symptoms.

Factors associated with physical function among people with systemic sclerosis: a SPIN cohort cross-sectional study.

Objectives: To compare physical function in systemic sclerosis (SSc, scleroderma) to general population normative data and identify associated factors.

Methods: Scleroderma Patient-centered Intervention Network Cohort participants completed the Physical Function domain of the Patient-Reported Outcomes Measurement Information System Version 2 upon enrolment. Multivariable linear regression was used to assess associations of sociodemographic, lifestyle, and disease-related variables.

Moderators of Loneliness Trajectories in People with Systemic Sclerosis During the COVID-19 Pandemic: A SPIN COVID-19 Cohort Longitudinal Study.

Background: Many individuals with systemic sclerosis (SSc) are at heightened risk for COVID-19 related morbidity and isolation due to interstitial lung disease, frailty, and immunosuppressant use. Minimal research has explored loneliness predictors in individuals with chronic illnesses during COVID-19. This study evaluated moderators of loneliness trajectories in individuals with SSc during COVID-19.

Objective: Some individuals with systemic sclerosis (SSc) report positive mental health, despite severe disease manifestations, which may be associated with resilience, but no resilience measure has been validated in SSc. This study was undertaken to assess the validity, reliability, and differential item functioning (DIF) between English- and French-language versions of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10) in SSc.

Methods: Eligible participants were enrolled in the Scleroderma Patient-centered Intervention Network Cohort and completed the CD-RISC-10 between August 2022 and January 2023.

Differences in Myocardial Remodeling and Tissue Characteristics in Chronic Isolated Aortic and Mitral Regurgitation.

Background: The left ventricular hemodynamic load differs between aortic regurgitation (AR) and primary mitral regurgitation (MR). We used cardiac magnetic resonance to compare left ventricular remodeling patterns, systemic forward stroke volume, and tissue characteristics between patients with isolated AR and isolated MR.

Methods: We assessed remodeling parameters across the spectrum of regurgitant volume.

A Novel Approach to Delivering Evidence-based, High-quality Care in Psychiatry Through an Electronic Integrated Care Pathway (eICP) Pilot.

Integrated care pathways (ICPs) are evidence-based decision support tools intended to reduce variation and improve quality of care. Historically, adoption of ICPs has been difficult to measure, as the pathways were outside of the electronic health record (EHR), where care delivery documentation and orders were completed. This Technology Column describes the innovative development and implementation of a diagnosis specific electronic ICP that directly embeds pathway steps into an EHR to facilitate order sets, clinical decision-making, and usage tracking.

The Assembled Genome of the Stroke-Prone Spontaneously Hypertensive Rat.

Background: We report the creation and evaluation of a de novo assembly of the genome of the spontaneously hypertensive rat, the most widely used model of human cardiovascular disease.

Methods: The genome is assembled from long read sequencing (PacBio HiFi and continuous long read data [CLR]) and scaffolded with long-range structural information obtained from Bionano optical maps and proximity ligation sequencing proximity analysis of the genome. The genome assembly was polished with Illumina short reads.

The objective of this feasibility trial was to evaluate aspects of feasibility for conducting a full-scale randomized controlled trial of the SPIN-HAND program.

Materials And Methods: The feasibility trial was embedded in the SPIN cohort and utilized the cohort multiple randomized controlled trial (cmRCT) design.

mRatBN7.2: familiar and unfamiliar features of a new rat genome reference assembly.

Rat genomic tools have been slower to emerge than for those of humans and mice and have remained less thorough and comprehensive. The arrival of a new and improved rat reference genome, mRatBN7.2, in late 2020 is a welcome event.

Randomized feasibility trial of the Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program.

Background: The Scleroderma Patient-centered Intervention Network (SPIN) developed an online self-management program (SPIN-SELF) designed to improve disease-management self-efficacy in people with systemic sclerosis (SSc, or scleroderma). The aim of this study was to evaluate feasibility aspects for conducting a full-scale randomized controlled trial (RCT) of the SPIN-SELF Program.

Methods: This feasibility trial was embedded in the SPIN Cohort and utilized the cohort multiple RCT design.

The Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program: protocol for a two-arm parallel partially nested randomized controlled feasibility trial with progression to full-scale trial.

Background: Systemic sclerosis (scleroderma; SSc) is a rare autoimmune connective tissue disease. We completed an initial feasibility trial of an online self-administered version of the Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program using the cohort multiple randomized controlled trial (RCT) design. Due to low intervention offer uptake, we will conduct a new feasibility trial with progression to full-scale trial, using a two-arm parallel, partially nested RCT design.

Strain-Specific Adaptations of to Serial In Vitro Passage in Daptomycin (DAP): Genotypic and Phenotypic Characteristics.

Viridans group streptococci (VGS), especially the subgroup, are pivotal pathogens in a variety of invasive endovascular infections, including "toxic shock" in neutropenic cancer patients and infective endocarditis (IE). Previously, we showed that the serial in vitro passage of strains in sublethal daptomycin (DAP) resulted in rapid, high-level and stable DAP-resistance (DAP-R), which is accompanied by distinct changes in several genotypic and phenotypic signatures: (1) the disappearance of two key membrane phospholipids, phosphatidylglycerol (PG) and cardiolipin (CL); (2) increased membrane fluidity; (3) increased positive surface charge; (4) single nucleotide polymorphisms (SNPs) in two loci involved in CL biosynthesis (); and (5) DAP hyperaccumulation. The current study examined these same metrics following in vitro serial DAP passages of a separate well-characterized bloodstream isolate (SF100).

Protocol for a partially nested randomised controlled trial to evaluate the effectiveness of the scleroderma patient-centered intervention network COVID-19 home-isolation activities together (SPIN-CHAT) program to reduce anxiety among at-risk scleroderma patients.

Objective: Contagious disease outbreaks and related restrictions can lead to negative psychological outcomes, particularly in vulnerable populations at risk due to pre-existing medical conditions. No randomised controlled trials (RCTs) have tested interventions to reduce mental health consequences of contagious disease outbreaks. The primary objective of the Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Trial is to evaluate the effect of a videoconference-based program on symptoms of anxiety.

Strengthening effects of bone marrow mononuclear cells with intensive atorvastatin in acute myocardial infarction.
