Assessment of electroencephalographic (EEG) activity in depression has provided insights into neural profiles of the illness. However, there is limited understanding on how symptom severity and risk factors, such as childhood adversity, influence EEG features. Eyes-closed EEG was acquired in N = 28 depressed individuals being treated in a tertiary psychiatric setting.

However, taxonomic and functional information are typically considered separately in downstream analyses. We develop interpretable machine learning (ML) approaches for modelling metagenomic data, combining the biological representation of species with their associated genetically encoded functions within models.

Methods: A retrospective study using surveillance data from the Haitian Unique Health Information System, examining two periods: pre- and peri-COVID-19 pandemic. Health indicators at the national level in the two periods were compared using two-sample -tests for proportions, and average absolute monthly changes were calculated using variance-weighted regression.
Self-determination plays an important role in outcomes in autism and shows intersectional disparities. Yet, little is known about the role of individual differences or social drivers of health in the development of self-determination. Understanding these factors is key for developing effective supports.

There is insufficient description regarding the timing, rate, and extent of the health status changes in heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) after initiation of SGLT2is.
Objectives: The authors sought to model the association of canagliflozin treatment with rates of change in HF symptom status in HFpEF and HFrEF.
Background: Wearable devices are increasingly used in research and clinical care though the relevance of their data in the context of validated outcomes remains unknown.
Objectives: The purpose of this study was to characterize the relationship between smartwatch activity and patient-centered outcomes in patients with heart failure.
Methods: CHIEF-HF (Canagliflozin: Impact on Health Status, Quality of Life and Functional Status in Heart Failure) was a randomized-controlled clinical trial that enrolled participants with heart failure and a compatible smartphone.
Background: Health status outcomes, including symptoms, function, and quality of life, are worse for Black compared with White patients with heart failure. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) reduce cardiovascular mortality and improve health status in patients with heart failure, but whether the health status benefit of SGLT2is is similar across races is not established. The objective of this study was to compare the treatment effect of SGLT2is (versus placebo) on health status for Black compared with White patients with heart failure.

The CHIEF-HF (Canagliflozin Impact on Health Status, Quality of Life and Functional Status in Heart Failure) trial was designed as a double-blind, randomized, fully decentralized clinical trial (DCT) that identified, consented, treated, and followed participants without any in-person visits. Patient-reported questionnaires were the primary outcome, which were collected by a mobile application.
View Article and Find Full Text PDFLarge traditional clinical trials suggest that sodium-glucose co-transporter 2 inhibitors improve symptoms in patients with heart failure and reduced ejection fraction (HFrEF) and in patients with heart failure and preserved ejection fraction (HFpEF). In the midst of the Coronavirus Disease 2019 pandemic, we sought to confirm these benefits in a new type of trial that was patient centered and conducted in a completely remote fashion. In the CHIEF-HF trial ( NCT04252287 ), 476 participants with HF, regardless of EF or diabetes status, were randomized to 100 mg of canagliflozin or placebo.

Objective: To evaluate the safety and functional outcomes of intravenous alteplase among patients who were taking NOACs prior to stroke and compare outcomes with patients who were not taking long-term anticoagulants.
Design, Setting, And Participants: A retrospective cohort study of 163 038 patients with acute ischemic stroke either taking NOACs or not taking anticoagulants prior to stroke and treated with intravenous alteplase within 4.
Background: Given signs and symptoms of hyperthyroidism are non-specific, thyroid studies may be completed to evaluate patients with vague complaints such as tachycardia in the emergency department (ED). We sought to determine how often a new diagnosis of hyperthyroidism was made in patients who underwent thyroid laboratory testing in the ED.
Objectives: The primary outcome of this study was a new diagnosis in the ED, or in the following 30 days, of hyperthyroidism or thyrotoxicosis following ED thyroid laboratory testing.
Background: The expense of clinical trials mandates new strategies to efficiently generate evidence and test novel therapies. In this context, we designed a decentralized, patient-centered randomized clinical trial leveraging mobile technologies, rather than in-person site visits, to test the efficacy of 12 weeks of canagliflozin for the treatment of heart failure, regardless of ejection fraction or diabetes status, on the reduction of heart failure symptoms.
Methods: One thousand nine hundred patients will be enrolled with a medical record-confirmed diagnosis of heart failure, stratified by reduced (≤40%) or preserved (>40%) ejection fraction and randomized 1:1 to 100 mg daily of canagliflozin or matching placebo.
Background: Improving adherence to direct oral anticoagulants (DOAC) is challenging, and simple text messaging reminders have not been effective.
Methods: SmartADHERE was a randomized trial that tested a personalized digital and human direct oral anticoagulant adherence intervention compared to usual care. Eligibility required age ≥ 18, newly-prescribed (≤90 days) rivaroxaban for atrial fibrillation (AF), 1 of 4 at-risk criteria for nonadherence, and a smartphone.
Purpose: Robotically-assisted total knee arthroplasty (TKA) has been shown to improve alignment and decrease outliers, an important goal in TKA procedures. The purpose of this cadaveric study was to compare the accuracy and reproducibility of a recently introduced TKA robotic system to conventional instrumentation for bone resections.
Methods: This cadaveric study compared 14 robotically-assisted TKA with 20 conventional TKAs.

The purpose of this study was to evaluate the antidepressant effects of a single ketamine infusion, a series of repeated ketamine infusions, and prolongation of response with maintenance infusions.
Methods: Forty-one participants with treatment-resistant depression completed a single-site randomized double-blind crossover comparison of single infusions of ketamine and midazolam (an active placebo control).
Background: In patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) with placement of stents, standard anticoagulation with a vitamin K antagonist plus dual antiplatelet therapy (DAPT) with a P2Y inhibitor and aspirin reduces the risk of thrombosis and stroke but increases the risk of bleeding. The effectiveness and safety of anticoagulation with rivaroxaban plus either one or two antiplatelet agents are uncertain.
Methods: We randomly assigned 2124 participants with nonvalvular atrial fibrillation who had undergone PCI with stenting to receive, in a 1:1:1 ratio, low-dose rivaroxaban (15 mg once daily) plus a P2Y inhibitor for 12 months (group 1), very-low-dose rivaroxaban (2.
