Selective Decarboxylative Fluorination of β-Keto Acids in Aqueous Media: F-NMR-Assisted Batch Optimization and Transfer to Continuous Flow.

The selective decarboxylative fluorination of 3-oxo-3-phenylpropionic acid is used as a benchmark reaction to optimize it under biocompatible conditions in batch and to transfer it to continuous flow mode. The reaction conditions are varied with respect to temperature, fluorinating reagents, inorganic base additives, and pH, as these parameters have been identified as having a significant impact on the process. The formation of the products and any by-products is analyzed using gas chromatography (GC) and F nuclear magnetic resonance spectroscopy (NMR).

Diagnostic Value of Serum Biomarkers for Invasive Aspergillosis in Haematologic Patients.

Background: Invasive aspergillosis (IA) is a significant cause of morbidity and mortality in patients with haematological malignancies. Accurate diagnosis of IA is challenging due to non-specific symptoms and the impact of antifungal prophylaxis on biomarker sensitivity.

Methods: This retrospective study evaluated the diagnostic performance of three serum biomarkers: Galactomannan Ag VirClia Monotest (VirClia), Wako β-D-Glucan Test (Wako BDG), and MycoGENIE Real-Time PCR (MycoGENIE PCR).

"A decade of candidaemia: A comprehensive analysis of prognosis and risk factors at a Belgian tertiary hospital".

Candidemia, predominantly caused by C. albicans, poses a significant threat in hospitals. Yet, non-albicans candidemia (NAC) and antifungal resistance are increasing concerns.

Comparison of testing methods assessing the in vitro efficacy of the combination of aztreonam with avibactam on multidrug-resistant Gram-negative bacilli.

Background: Aztreonam-avibactam (ATM-AVI) combination shows promising effectiveness on most carbapenemase-producing Gram-negatives, yet standardized antibiotic susceptibility testing (AST) methods for evaluating the combination in clinical laboratories is lacking. We aimed to evaluate different ATM-AVI AST approaches.

Methods: 96 characterized carbapenem-resistant clinical isolates belonging to 9 Enterobacterales (EB; n = 80) and P.

Photosensitivity and self-induction in patients aged 50 and older.

Objective: Photosensitivity is known to occur predominantly in children and adolescents and with a clear female predominance. Little is known on the prevalence of photosensitivity in older patients (50+) and its phenotypical appearance.

Methods: A retrospective observational study was performed investigating the prevalence of a photoparoxysmal EEG response (PPR) on at least one EEG during the period 2015-2021.
