Importance: Restrictions related to the COVID-19 pandemic disrupted the lives of young children, but the association between the pandemic and any changes in early childhood developmental milestone achievement in the US remains unclear.

Objectives: To determine the association between the COVID-19 pandemic and changes in developmental screening scores among US children aged 0 to 5 years and to investigate whether caregivers self-reported more worries about their children or concerns about children's behavior during the pandemic, regardless of milestone achievement.

Design, Setting, And Participants: This was a cohort study using an interrupted time series analysis comparing prepandemic (March 1, 2018, to February 29, 2020), interruption (March 1 to May 31, 2020), and intrapandemic (June 1, 2020, to May 30, 2022) periods among 50 205 children (randomly sampled from a population of 502 052 children) aged 0 to 5 years whose parents or caregivers completed developmental screening at pediatric visits at US pediatric primary care practices participating in a web-based clinical process support system.

Objective: School-based health centers (SBHCs) improve health care access, but associations with educational outcomes are mixed and limited for elementary and middle school students. We investigated whether students enrolled in a comprehensive SBHC demonstrated more growth in standardized math and reading assessments over 4 school years versus nonenrolled students. We also explored changes in absenteeism.

The objective of this study was to indirectly compare QDOT MICRO™ (QDOT), Thermocool SmartTouch™ (ST) and Thermocool SmartTouch Surround Flow (STSF) to treat paroxysmal atrial fibrillation. Differences in baseline characteristics between study cohorts were reduced by reweighting patients using inverse probability of treatment weighting. The primary outcome was procedure time.

Many patients with lower-risk myelodysplastic syndromes (LR MDS) require long-term red blood cell (RBC) transfusions to manage anemia. The consequences of RBC transfusions in LR MDS with ring sideroblasts (LR MDS-RS) are not well known. We estimated the association between cumulative RBC dose density and clinical and patient-reported outcomes using data from the MDS-CAN registry for patients enrolled between January 2008 and December 2018.

Patients with lower-risk (LR) myelodysplastic syndromes (MDS) with ring sideroblasts (RS) have better prognosis than those without RS, but how they fare over time is not fully understood. This study's objective was to assess the natural history of LR MDS with RS ≥5% using MDS-CAN registry individual data. Kaplan-Meier estimates and generalized linear mixed models were used to describe time-to-event outcomes and continuous outcomes, respectively.

Objective: Schools with aging infrastructure may expose students to extreme temperatures. Extreme outdoor temperatures have previously been linked to more asthma-related health care utilization. Explore the relationship between classroom temperatures and school-based health care visits for asthma in an urban school building with an outdated heating and cooling system.

Objective: Head-to-head trials comparing siponimod with fingolimod or ofatumumab in patients with multiple sclerosis (MS) are lacking. Instead, the comparative efficacy of siponimod can be derived from indirect treatment comparisons (ITCs). We assessed the suitability of ITCs leveraging individual patient data from relevant phase III trials across different MS phenotypes.

Introduction: Both radiofrequency (RF) and cryoballoon (CB) ablation are treatment options for persistent atrial fibrillation (PsAF). An important recent innovation in RF ablation is Ablation Index (AI), known also as the VISITAG SURPOINT™ Module, a composite lesion quality marker whose use has been shown to significantly reduce the incidence of acute and late pulmonary vein (PV) reconnection and the recurrence of atrial arrhythmias in PsAF. Due to a lack of direct comparative evidence between the latest generations of technologies, there is uncertainty regarding the best treatment option in PsAF.

Most patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) have exhausted their treatment options and are deemed palliative. CD19-directed chimeric antigen receptor (CAR) T-cell therapy has recently been introduced as a new option for these patients. Lisocabtagene maraleucel (liso-cel) is an investigational CAR T-cell therapy that has shown promising activity in this setting.

Glasses wearing at school remains low even when glasses are provided. This study investigated whether a classroom intervention to promote glasses wearing was associated with increased glasses wearing and improved classroom behavior. A pretest, posttest design was implemented with 44 students in Grades 1-4 at an urban public elementary school.

Children with overweight status and obesity seek care for acute illnesses more often than normal weight peers. School-based health centers (SBHCs) have a role in acute and chronic disease management; however, little is known about SBHC use by children with overweight status and obesity. This study compared SBHC utilization by student body mass index (BMI) category and investigated whether SBHC visit diagnoses varied by BMI category.

Introduction: Ablation Index, also known as VISITAG SURPOINT™, is a novel lesion-quality marker that improves outcomes in radiofrequency (RF) catheter ablation of atrial fibrillation (AF). There is no direct evidence on the comparative effectiveness of RF ablation with Ablation Index and cryoballoon (CB). The objective of the present study was to conduct a matching-adjusted indirect comparison (MAIC) using individual patient-level data (IPD) to compare the effectiveness of RF ablation with Ablation Index to that of CB on recurrence of atrial arrhythmias 12 months after catheter ablation in patients with paroxysmal AF (PAF).

Introduction: Asthma is linked to student absenteeism, a risk factor for poor achievement and school dropout. Studies of asthma and absenteeism have common limitations, including relying on parent-reported asthma, which may be unreliable and prone to selection, and inadequately accounting for confounding health and social risks. Therefore, the rate of absenteeism attributable to asthma and the extent to which better asthma control would translate into better attendance remain unclear.

Background: Despite evidence demonstrating the advantages of metered-dose inhalers with spacers (MDI-s), nebulization (NEB) remains the primary method of asthma treatment in some pediatric emergency departments (PEDs). There is a perception that delivering salbutamol by MDI-s is more costly than by NEB. This research evaluates the relative costs of MDI-s and NEB using local, hospital-specific, patient-level data.
