Increased Antibiotic Susceptibility of Gram-Positive Bacteria in Cerebrospinal Fluid Compared to Broth.

In hospital- and community-acquired central nervous system infections, resistant Gram-positive bacteria are an increasing therapeutic challenge. The present approach does not attempt to identify rapidly bactericidal therapies for susceptible pathogens but aims to improve methods to find antibiotic regimens for multi-resistant pathogens that are effective in vivo in spite of reduced in vitro susceptibility in culture media. Antibiotic susceptibility was tested in cerebrospinal fluid (CSF) and Mueller-Hinton broth (, methicillin-resistant , ) or brain-heart infusion ().

Optimization of antiviral dosing in Herpesviridae encephalitis: a promising approach to improve outcome?

Background: Despite established antiviral therapy for herpes simplex virus, varicella zoster and cytomegalovirus encephalitis, the outcome remains poor.

Objectives: To assess pharmacokinetic (PK) and pharmacodynamic (PD) data of antiviral drugs in the central nervous system (CNS) to optimize the treatment of Herpesviridae encephalitis.

Sources: PUBMED search 1950 to September 2024, terms (1) "encephalitis" and ("HSV" or "VZV" or "CMV") or (2) cerebrospinal and ("(val)acyclovir" or "(val)ganciclovir" or "foscarnet" or "cidofovir").

Decreased Phagocytosis and Intracellular Killing of Bacteria in Leukocytes of Geriatric Patients with Clostridioides difficile Infections.

Introduction: Patients suffering from a Clostridioides difficile infection have a higher overall mortality than patients with similar comorbidities.

Methods: Whole blood samples of 15 patients with C. difficile enteritis and 15 control patients matched for age and sex were used to analyze the capacity of blood phagocytes to internalize and kill encapsulated Escherichia (E.

Hyponatremia in geriatric patients.

Hyponatremia is the most frequent electrolyte imbalance in geriatric medicine. Causes of hyponatremia were retrospectively analyzed in all in-patients treated in 2016 (N = 2267, 1564 women, 703 men, mean age ± standard deviation 81.9 ± 7.

Gum Arabic Increases Phagocytosis of by Blood Leukocytes of Young and Old Healthy Volunteers.

Background: Gum arabic, a polysaccharide exudate from (L.) Willdenow trees, has already been used by African native people in natural medicine.

Methods: Using whole-blood samples from young (20-35 years) and older (>80 years) healthy volunteers (each group n = 10), the effect of an aqueous solution of GA on phagocytosis of was examined with a gentamicin protection assay.
