Purpose: For patients with celiac disease (CeD), the only current management option is adherence to a strict gluten-free diet (GFD); however, many patients on a GFD continue to experience symptoms with a significant impact on quality of life. Potential new treatments for CeD are under development and a validated patient-reported outcome measure is required to evaluate their utility in clinical trials. The purpose of this article is to provide a history of the development of the Celiac Disease Symptom Diary (CDSD) 2.

Background: Clinical trials (PALISADE [ARC003], ARTEMIS [ARC010]) proving efficacy and safety of peanut (Arachis hypogaea) allergen powder-dnfp (PTAH) have used double-blind, placebo-controlled food challenges (DBPCFCs) to screen for eligibility and to evaluate efficacy. In routine clinical practice, individuals with peanut allergy do not always undergo food challenges to confirm diagnosis or determine candidacy for treatment.

Objective: To describe PTAH safety and tolerability in participants selected by clinical history and peanut sensitization parameters not undergoing DBPCFCs during trials and to compare findings with previously published data.

Having an interpretable dynamic length-of-stay (LOS) model can help hospital administrators and clinicians make better decisions and improve the quality of care. The widespread implementation of electronic medical record (EMR) systems has enabled hospitals to collect massive amounts of health data. However, how to integrate this deluge of data into healthcare operations remains unclear.

Article Synopsis
  • - The PALISADE study investigated the effects of peanut oral immunotherapy (POIT) using AR101 on peanut-allergic children, demonstrating that it can lead to desensitization and positive immunological changes.
  • - Blood samples showed that participants who successfully desensitized had lower basophil sensitivity and T-cell reactivity to peanuts compared to those who reacted during the challenge test, indicating a significant shift in their immune response.
  • - The results support the idea that AR101 therapy reshapes peanut-reactive T cells, enhancing clinical outcomes while suggesting the therapy's potential as a future treatment option for peanut allergies.

Background: Eliciting doses (EDs) (eg, ED or ED values, which are the amounts of allergen expected to cause objective symptoms in 1% and 5% of the population with an allergy, respectively) are increasingly being used to inform allergen labeling and clinical management. These values are generated from food challenge, but the frequency of anaphylaxis in response to these low levels of allergen exposure and their reproducibility are unknown.

Objective: Our aim was to determine (1) the rate of anaphylaxis in response to low-level peanut exposure and (2) the reproducibility of reaction thresholds (and anaphylaxis) at food challenge.

It is thought that there are not enough mechanical ventilators in the United States for every patient who may need one during the novel coronavirus disease (COVID-19) pandemic. However, there has been no analysis that measures the potential magnitude of the problem or proposes a solution. In this article I combine the pandemic forecasting model used by the federal government with estimates of ventilator availability from the literature to assess the expected shortage under various scenarios.

Background: Celiac disease (CD) is a widespread autoimmune disease triggered by dietary gluten that can lead to severe gastrointestinal symptoms. Because there is no available treatment other than a lifelong gluten-free diet, many patients continue to experience chronic symptoms.

Aim: In this analysis we report on the efficacy of latiglutenase, an orally administered enzyme treatment, for improving multiple gluten-induced symptoms and consequent quality of life (QOL) due to inadvertent gluten consumption.

Background: Peanut allergy, for which there are no approved treatment options, affects patients who are at risk for unpredictable and occasionally life-threatening allergic reactions.

Methods: In a phase 3 trial, we screened participants 4 to 55 years of age with peanut allergy for allergic dose-limiting symptoms at a challenge dose of 100 mg or less of peanut protein (approximately one third of a peanut kernel) in a double-blind, placebo-controlled food challenge. Participants with an allergic response were randomly assigned, in a 3:1 ratio, to receive AR101 (a peanut-derived investigational biologic oral immunotherapy drug) or placebo in an escalating-dose program.

Small intestinal histologic abnormalities in celiac disease include atrophy of the intestinal villi, hypertrophy of the crypts and lymphocytic infiltration of intraepithelial spaces and lamina propria. These findings are central to diagnosis and their severity and change over time are valuable to monitor disease course and response to therapy. Subjective methods to grade celiac disease histological severity include the Marsh-Oberhuber and Corazza-Villanacci systems.

Background: A multidisciplinary team at a major academic medical center established an Acutely Decompensated Heart Failure Clinical Pathway (ADHFCP) program to reduce inpatient readmission rates among patients with heart failure which, among several interventions, included an immediate consultation from a cardiologist familiar with an ADHFCP patient when the patient presented at the Emergency Department (ED). This study analyzed how that program impacted utilization of services in the ED and its subsequent effect on rates of admission from the ED and on disposition times.

Methods: ADHFCP inpatient visits were retrospectively risk stratified and matched with non-program inpatient visits to create a control group.

Background: Re-hospitalization after discharge for acute decompensated heart failure is a common problem. Low-socioeconomic urban patients suffer high rates of re-hospitalization and often over-utilize the emergency department (ED) for their care. We hypothesized that early consultation with a cardiologist in the ED can reduce re-hospitalization and health care costs for low-socioeconomic urban patients with acute decompensated heart failure.
