Rectangular Repetitive Transcranial Magnetic Monophasic vs Biphasic Stimulation for Major Depressive Disorder: A Randomized Controlled Pilot Trial.

Objectives: Biphasic sinusoidal repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation treatment that has been approved by the US Food and Drug Administration for treatment-resistant depression (TRD). Recent advances suggest that standard rTMS may be improved by altering the pulse shape; however, there is a paucity of research investigating pulse shape, owing primarily to the technologic limitations of currently available devices. This pilot study examined the feasibility, tolerability, and preliminary efficacy of biphasic and monophasic rectangular rTMS for TRD.

The expected polygenic risk score (ePRS) framework: an equitable metric for quantifying polygenetic risk via modeling of ancestral makeup.

Polygenic risk scores (PRSs) depend on genetic ancestry due to differences in allele frequencies between ancestral populations. This leads to implementation challenges in diverse populations. We propose a framework to calibrate PRS based on ancestral makeup.

Three Underused Statistical Methods in Social Epidemiology: Multiple Informant Models, Fractional Regression, and Restricted Mean Survival Time.

We recommend three well-established yet underused statistical methods in social epidemiology: Multiple Informant Models (MIMs), Fractional Regression Model (FRM), and Restricted Mean Survival Time (RMST). MIMs improve how we identify critical windows of exposure over time. FRM addresses the inadequacies of ordinary least squares and logistic regression when dealing with fractional outcomes that are naturally proportions or rates, thereby accommodating data at the boundaries of the unit interval without requiring transformations.

Upconverting microgauges reveal intraluminal force dynamics in vivo.

The forces generated by action potentials in muscle cells shuttle blood, food and waste products throughout the luminal structures of the body. Although non-invasive electrophysiological techniques exist, most mechanosensors cannot access luminal structures non-invasively. Here we introduce non-toxic ingestible mechanosensors to enable the quantitative study of luminal forces and apply them to study feeding in living Caenorhabditis elegans roundworms.

Healthcare Utilization Patterns in Sickle Cell Patients and Their Association With Sickle Cell Retinopathy.

Background/aim: A few shave identified systemic and hematologic risk factors for Proliferative Sickle Cell Retinopathy (PSR) development. The relevance of healthcare utilization as a risk factor for PSR has not been defined. This study evaluates patterns of healthcare utilization among patients with sickle cell disease (SCD) and retinopathy.
