Background: Few studies have investigated the risk of psychiatric neurodevelopmental disorders (PNDD) after childhood meningitis.

Methods: Nationwide population-based cohort study (Denmark, 1995-2021) of children with positive cerebrospinal fluid for bacteria or enterovirus, stratified on age as young infants (0 to <90 days,  = 637) or older children (≥90 days to <17 years,  = 1,218). We constructed a comparison cohort from the general population ( = 18,550), and cohorts of siblings of participants.

Article Synopsis
  • The study aimed to examine how often patients with neuroborreliosis receive additional antibiotic treatment after their initial doxycycline therapy due to lingering symptoms.
  • Conducted in Denmark between 2009-2021, the research compared 463 neuroborreliosis patients with 2,315 matched individuals from the general population, focusing on doxycycline and phenoxymethylpenicillin usage.
  • Results showed that neuroborreliosis patients were significantly more likely to receive doxycycline again within one year (38.6 times more) compared to the general population, while there was no difference in phenoxymethylpenicillin prescriptions, indicating a specific need for doxycycline rather than just healthcare-seeking behavior.

Background: Lyme borreliosis is a tick-borne disease caused by the bacterium Borrelia burgdorferi (Bb) sensu lato complex. Previous studies have suggested an association between Lyme borreliosis and heart failure, which have been suggested to be a possible manifestation of Lyme carditis. We aimed to investigate the risk of heart failure among individuals tested for serum Bb antibodies, and serum Bb seropositive individuals.

Objectives: To investigate the short- and long-term risks of atrioventricular block and other cardiac conduction disorders associated with being tested for Borrelia burgdorferi (Bb) antibodies or Bb seropositivity as measures of confounding by indication and Bb infection, respectively.

Methods: We performed a nationwide population-based matched cohort study (Denmark, 1993-2021). We included 52 200 Bb-seropositive individuals (stratified as only Bb-IgM-seropositive [n = 26 103], only Bb-IgG-seropositive [n = 18 698], and Bb-IgM-and-IgG-seropositive [n = 7399]) and two age- and sex-matched comparison cohorts: 104 400 Bb-seronegative individuals and 261 000 population controls.

Objectives: In a nationwide, matched cohort study, we aimed to investigate risks of haematologic cancers among individuals tested for Borrelia burgdorferi (Bb) antibodies, and among serum Bb seropositive individuals.

Methods: We identified all Bb seropositive individuals in Denmark (1993-2020) (n = 52 200) and constructed two age- and sex-matched comparison cohorts: (a) Bb seronegative controls (n = 104 400) and (b) background population controls (n = 261 000). We calculated short-term OR (aOR) (<1 month of study inclusion), and long-term hazard ratios (aHR) (>1 month after study inclusion) adjusted for age and sex.
