Retrospective Cohort Study on the Predictive Value of Primary Non-response to Initial Biologic for Future Biologic Use in Patients with Inflammatory Bowel Disease.

Background: The armamentarium of medical therapies to treat inflammatory bowel disease (IBD) continues to grow, which has expanded treatment options, particularly after first biologic failure. Currently, there are limited studies investigating the predictive value of first biologic primary non-response (PNR) on subsequent biologic success. Our objective was to determine if PNR to the first biologic for IBD is predictive of response to subsequent biologic therapy.

Epidermal Collagen Reduction Drives Selective Aspects of Aging in Sensory Neurons.

Despite advances in understanding molecular and cellular changes in the aging nervous system, the upstream drivers of these changes remain poorly defined. Here, we investigate the roles of non-neural tissues in neuronal aging, using the cutaneous PVD polymodal sensory neuron in Caenorhabditis elegans as a model. We demonstrate that during normal aging, PVD neurons progressively develop excessive dendritic branching, functionally correlated with age-related proprioceptive deficits.

Fractional flow reserve-guided complete revascularization versus culprit-only percutaneous coronary intervention in patients with myocardial infarction: A meta-analysis of randomized controlled trials.

Introduction: The optimal revascularization strategy for patients with myocardial infarction (MI) and multivessel coronary artery disease (CAD) remains an area of research and debate. Fractional flow reserve (FFR)-guided complete revascularization (CR) by percutaneous coronary intervention (PCI) has emerged as an alternative to traditional culprit-only PCI.

Objective: To investigate the outcomes of FFR-guided CR versus culprit-only PCI in patients with MI and multivessel CAD.

Efficacy of combination therapy with mometasone and montelukast versus mometasone alone in treatment of adenoid hypertrophy in children: A systematic review and meta-analysis.

Introduction: Intranasal mometasone and oral montelukast have been found to be effective for adenoid hypertrophy in children. We aimed to compare the efficacy of combination therapy of mometasone and montelukast versus mometasone alone for adenoid hypertrophy in children.

Methods: Following PRISMA guidelines, we systematically searched PubMed, Embase, Cochrane CENTRAL, and ClinicalTrials.

Limits to timescale dependence in erosion rates: Quantifying glacial and fluvial erosion across timescales.

Earth's topography and climate result from the competition between uplift and erosion, but it has been debated whether rivers or glaciers are more effective erosional agents. We present a global compilation of fluvial and glacial erosion rates alongside simple numerical experiments, which show that the "Sadler effect," wherein geological rates show an inverse relationship with measurement timescale, comprises three distinct effects: a measurement thickness bias, a bias of erosion and redeposition, and a bias introduced by not observing quiescent intervals. Furthermore, we find that, globally, average glacial erosion rates exceed fluvial erosion rates through time by an order of magnitude, and that this difference cannot be explained by Sadlerian biases or by variations in hillslope, precipitation, or latitude.
