Safety and Efficacy of Ventricular Irrigation for Ventriculitis

Ventriculitis is a severe infectious disease of the central nervous system with diverse etiologies. Currently, the treatment for ventriculitis is challenging, with poor prognosis. The mortality rate of ventriculitis is generally reported to be higher than 30%, with the highest reaching over 75%. Even among survivors, over 60% suffer from a variety of neurological sequelae, including cognitive impairment, gait disturbances, paralysis, behavioral disorders, and epilepsy. Currently, treatments for ventriculitis recommended by guidelines primarily focus on the selection and administration of antibiotics, while the effects of surgical interventions have not been fully elucidated. In recent years, several studies have explored the use of ventricular irrigation in ventriculitis, indicating that ventricular irrigation techniques may accelerate the control of ventricular infection, mitigate damage to the central nervous system caused by infections, improve the prognosis of ventriculitis, and reduce complications such as hydrocephalus. However, current studies are still relatively scarce, and mostly case reports and retrospective studies. High-quality evidence is still lacking for the application of ventricular irrigation in ventriculitis. This multicenter randomized controlled trial aims to explore the safety and effectiveness of ventricular irrigation compared to conventional treatment for ventriculitis, analyze the effectiveness of ventricular irrigation across different pathogen subgroups, and investigate independent risk factors for different prognostic states in patients with ventriculitis.

Machine Learning to Predict Factors Affecting Rehabilitation Length of Stay and Healthcare Costs for Neurological Rehabilitation

The aim of this retrospective study is to ascertain total direct costs, rehabilitation length of stay (RLOS) and factors associated with RLOS for neurological inpatient rehabilitation at the tertiary care hospital.

Comparing Tigecycline Vs. Colistimethate in CNS Infections

This observational study compares the efficacy and safety of tigecycline, an alternative antibiotic with broad-spectrum activity, versus the standard colistimethate sodium-based regimen in managing these infections in pediatric patients. Inclusion Criteria: Pediatric patients aged 1 month to 18 years. Presence of CNS infection symptoms such as fever, altered mental status, and positive cerebrospinal fluid (CSF) findings. EVD placement for managing CNS infections. Exclusion Criteria: Known allergy to tigecycline or colistimethate sodium. Patients with concurrent severe comorbid conditions that may confound study results. Neonates (less than 1 month old), pregnant, or breastfeeding patients. Outcome Measures: Primary Outcomes: Clinical cure (resolution of infection symptoms) and microbiological cure (sterilization of CSF cultures). Secondary Outcomes: Mortality rates and adverse drug events, such as nephrotoxicity, hepatotoxicity, chemical meningitis, or seizures.

INfectious DIsease REgistry BIObank

Prospective observational study designed to describe the clinical, laboratory, imaging, microbiological characteristics and treatment of specific infectious diseases, with the addition of a dedicated biobank.

Central Nervous System Infections in Denmark

The Danish Study Group of Infections of the Brain is a collaboration between all departments of infectious diseases in Denmark. The investigators aim to monitor epidemiological trends in central nervous system (CNS) infections by a prospective registration of clinical characteristics and outcome of all adult (\>17 years of age) patients with community-acquired CNS infections diagnosed and/or treated at departments of infectious diseases in Denmark since 1st of January 2015.

Device-related Central Nervous System Infections in Adult Intensive Care Units in Brazil

Resistant microorganisms are public health problems because they affect the treatment of infectious diseases and the survival of patients. Neurosurgical procedures with placement of intracranial pressure monitoring and external ventricular drainage devices are related to increased morbidity and mortality. In Brazil, there are several multicenter studies demonstrating the prevalence and types of resistant microorganisms, however, there is a lack of data related to central nervous system infections associated with invasive devices, which can have a direct impact on prevention and treatment policies.

Effect of a Bundle of Interventions on the Outcomes of Patients With Intracranial Devices (ICP Monitor e EVD)

Non-randomized clinical trial conducted in the adult ICUs of Brazilian hospitals participating in the IMPACTO MR Platform, involving adult patients using an intracranial pressure monitoring catheter device or external ventricular drain. The study will test the hypothesis that the intervention bundle, following ANVISA recommendations for care practices, will reduce the rates of central nervous system infections associated with ICP and EVD devices. This reduction is expected to lead to more accurate diagnoses, decreased antibiotic usage, shortened ICU and hospital stays, and reduced hospital costs.
