Study of Mesostructured CeO Synthesis via Nanocasting Using SBA-15 as a Template: Influence of the Cerium Precursor.

Mesoporous materials with high surface area, large pore volume, and adjustable pore size are promising in the fields of adsorption and heterogeneous catalysis. In this work, ordered mesoporous ceria structures were successfully prepared via nanocasting using SBA-15 as a template, with Ce(NO)·6HO or CeCl·7HO as ceria precursors. The materials were characterized before and after template removal.

Dissecting Secondary Immunodeficiency: Identification of Primary Immunodeficiency within B-Cell Lymphoproliferative Disorders.

Distinguishing between primary (PID) and secondary (SID) immunodeficiencies, particularly in relation to hematological B-cell lymphoproliferative disorders (B-CLPD), poses a major clinical challenge. We aimed to analyze and define the clinical and laboratory variables in SID patients associated with B-CLPD, identifying overlaps with late-onset PIDs, which could potentially improve diagnostic precision and prognostic assessment. We studied 37 clinical/laboratory variables in 151 SID patients with B-CLPD.

Improvement of Early Outcomes in Type A Acute Aortic Syndrome After an Aorta Code Implementation.

Background: Reduction of variability through process reengineering can improve surgical results for patients with type A acute aortic syndrome. We compare short-term results before and after implementation of an Aorta Code for patients with type A acute aortic syndrome who underwent surgery.

Methods: The Aorta Code was implemented in a 5-hospital healthcare network in 2019.

A Four-Year Survey of Hemoparasites from Nocturnal Raptors (Strigiformes) Confirms a Relation between and Low Hematocrit and Body Condition Scores of Parasitized Birds.

Most hemoparasites hosted by wild birds appear to be harmless, but most of the blood parasite studies in avian wildlife are mainly focused on passerines or migratory species. This study aimed to assess the occurrence of blood parasites in nocturnal raptors (Strigiformes order) and their effect on hematological parameters. A total of 134 blood samples were collected during a four-year period for hematological analysis and hemoparasite detection and quantification by microscopical examination of the samples.

Return to Sports After Total Hip Arthroplasty: An Umbrella Review for Consensus Guidelines.

Background: Current recommendations on safe return to sports (RTS) after total hip arthroplasty (THA) are subjective and based on studies of varying quality.

Purpose: The aim of this study was to synthesize systematic reviews and meta-analyses on post-THA RTS to propose practice guidelines identifying which sports can be resumed, when they can be resumed, and what risks are present.

Study Design: Systematic review; Level of evidence, 4.
