The Effectiveness of Budesonide Once Daily as Maintenance Treatment of Eosinophilic Esophagitis.

Background: Swallowed topical corticosteroids (STC) are an effective first-line therapy for patients with eosinophilic esophagitis (EoE), both for induction and maintenance of remission. All interventional trials with STC used twice-daily dosing regimens. However, in other inflammatory gastrointestinal disorders, corticosteroids are given once daily (OD) with equal outcomes and improved compliance.

Three-Dimensional CT for Preprocedural Planning of PCI for Ostial Right Coronary Artery Lesions: A Randomized Controlled Pilot Trial.

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Early phosphate changes as potential indicator of unreadiness for artificial feeding: a secondary analysis of the EPaNIC RCT.

Background: As compared to withholding parenteral nutrition (PN) until one week after intensive care unit (ICU) admission, Early PN prolonged ICU dependency in the EPaNIC randomized controlled trial (RCT). The Refeeding RCT showed improved outcome by temporary macronutrient restriction in ICU patients developing refeeding hypophosphatemia, defined as a phosphate decrease of > 0.16 mmol/L to levels < 0.

The role of nutritional vitamin D in CKD-MBD in children and adults with CKD, on dialysis and after kidney transplantation - a European consensus statement.

Vitamin D deficiency is common in patients with chronic kidney disease (CKD) and associates with poor outcomes. Current clinical practice guidelines recommend supplementation with nutritional vitamin D as for the general population. However, recent large-scale, clinical trials in the general population failed to demonstrate a benefit of vitamin D supplementation on skeletal or non-skeletal outcomes, fueling a debate on the rationale for screening for and correcting vitamin D deficiency, both in non-CKD and CKD populations.

Nivolumab plus ipilimumab versus nivolumab in microsatellite instability-high metastatic colorectal cancer (CheckMate 8HW): a randomised, open-label, phase 3 trial.

Background: CheckMate 8HW prespecified dual primary endpoints, assessed in patients with centrally confirmed microsatellite instability-high or mismatch repair-deficient status: progression-free survival with nivolumab plus ipilimumab compared with chemotherapy as first-line therapy and progression-free survival with nivolumab plus ipilimumab compared with nivolumab alone, regardless of previous systemic treatment for metastatic disease. In our previous report, nivolumab plus ipilimumab showed superior progression-free survival versus chemotherapy in first-line microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer in the CheckMate 8HW trial. Here, we report results from the prespecified interim analysis for the other primary endpoint of progression-free survival for nivolumab plus ipilimumab versus nivolumab across all treatment lines.
