Bioavailability of a novel sustained-release pellet formulation of 5-flucytosine in healthy-fed participants for use in patients with cryptococcal meningitis.

Cryptococcal meningoencephalitis (CM) is an opportunistic fungal infection and a major cause of death among people living with human immunodeficiency virus in sub-Saharan Africa. 5-flucytosine (5-FC) is a unique, brain-permeable antifungal agent used to reduce mortality from CM and to prevent disease in individuals carrying cryptococcal antigen. 5-FC has a short plasma half-life, requiring 6-hourly oral dosing with an immediate-release (IR) formulation, a significant challenge in hospital and outpatient settings, risking a lack of compliance.

Bioavailability of three novel oral, sustained-release pellets, relative to an immediate-release tablet containing 500 mg flucytosine: A randomized, open-label, crossover study in healthy volunteers.

The opportunistic fungal infection cryptococcal meningoencephalitis is a major cause of death among people living with HIV in sub-Saharan Africa. We report pharmacokinetic (PK) and safety data from a randomized, four-period crossover phase I trial of three sustained-release (SR) oral pellet formulations of 5-flucytosine conducted in South Africa. These formulations were developed to require less frequent administration, to provide a convenient alternative to the current immediate release (IR) formulation, A.

Comparison of in-person versus virtual ultrasound instruction for pediatric residents.

Purpose: Point-of-care ultrasound (POCUS) instruction is prevalent in medical schools but not in pediatric residency programs, even though the majority of pediatric residents desire POCUS instruction. Virtual ultrasound instruction with affordable handheld ultrasound devices may help remedy this deficiency by allowing qualified instructors to circumvent geographic and financial limitations to reach this population. This study sought to determine if virtual ultrasound instruction is an effective alternative to traditional in-person instruction in a cohort of pediatric residents for the extended Focused Assessment with Sonography in Trauma (eFAST) exam.

Effect of food on the pharmacokinetics of zoliflodacin granules for oral suspension: Phase I open-label randomized cross-over study in healthy subjects.

Gonorrhea is a sexually transmitted infection for which antibiotic treatment options have declined due to increasing antibiotic resistance. Zoliflodacin, an investigational oral spiropyrimidinetrione antibiotic with activity against Neisseria gonorrhoeae strains that are multidrug-resistant, including to third-generation cephalosporins, is in phase III development for uncomplicated gonorrhea. This phase I, parallel, open-label, randomized, crossover study in healthy adults evaluated the effect of food on the pharmacokinetics of single 3 or 4 g doses of zoliflodacin administered as granules for oral suspension in the fasted state or after consumption of a standardized high-fat meal.
