Current epidemiology of infectious encephalitis: a narrative review.

Background: Infectious encephalitis poses a global health challenge with a high mortality and severe neurological consequences in survivors. Emerging pathogens and outbreaks are reshaping the patterns of the disease.

Objective: To understand the current epidemiology for improving prevention, diagnosis, and treatment.

Brain Abscess Caused by Oral Cavity Bacteria: A Nationwide, Population-based Cohort Study.

Background: Oral cavity bacteria are the most frequent etiology of brain abscess. Yet, data on the clinical presentation and outcome are scarce.

Methods: We performed a nationwide, population-based study comprising all adults (aged ≥18 years) with brain abscess due to oral cavity bacteria in Denmark from 2007 through 2020.

Risk Factors and Prognosis of Epilepsy Following Brain Abscess: A Nationwide Population-Based Cohort Study.

Background And Objectives: Epilepsy in patients with brain abscess is frequent, but risk factors and prognosis remain undetermined. This study examined risk factors of epilepsy among survivors of brain abscess and associated prognosis.

Methods: Nationwide, population-based healthcare registries were used to compute cumulative incidences and cause-specific adjusted hazard rate ratios (adj.

Clinical features and prognostic factors in adults with brain abscess.

Studies on brain abscess are hampered by single-centre design with limited sample size and incomplete follow-up. Thus, robust analyses on clinical prognostic factors remain scarce. This Danish nationwide, population-based cohort study included clinical details of all adults (≥18 years) diagnosed with brain abscess in the Danish National Patient Registry from 2007 through 2014 and the prospective clinical database of the Danish Study Group of Infections of the Brain covering all Danish departments of infectious diseases from 2015 through 2020.

Positive Predictive Value of the ICD-10 Diagnosis Code for Long-COVID.

Purpose: To examine the positive predictive value (PPV) of International Classification version 10 (ICD-10) diagnosis codes for long coronavirus disease 2019 (long-COVID) in a Danish Health registry.

Patients And Methods: This was a medical record review of all patients with a diagnosis code of long-COVID (DB948A) at all hospitals in the North Denmark Region from February 27, 2020 through June 30, 2021. Confirmed long-COVID was categorized as fulfillment of all three criteria: (1) a positive polymerase chain reaction (PCR) test for SARS-CoV-2 on a respiratory sample or a positive serum antibody test, (2) symptoms suggestive of long-COVID with no other diagnosis considered more likely, and (3) symptom duration >6 weeks.
