Categorization systems for tick-borne encephalitis virus (TBEV) infection lack consistency in classifying disease severity. To evaluate the need for a standard, consensus-based categorisation system for TBEV infection across subtypes, we gathered an expert panel of clinicians and scientists with diverse expertise in TBEV infection. Consensus was sought using the Delphi technique, which consisted of 2 web-based survey questionnaires and a final, virtual, consensus-building exercise.

The increasing number of cases of tick-borne encephalitis (TBE) reported in recent years in Europe and, more recently, in Poland is a consequence of factors related to climate and environmental change leading to increasing tick populations and human behavior favoring exposure. In Poland, there is considerable regional variation in the incidence of TBE, resulting, among other factors, from underreporting of all cases and limited access to laboratory diagnostics. The consequence is low public awareness of the disease and insufficient use of vaccination as optimal prevention.

Article Synopsis
  • This study analyzed 331 patients with primary brain abscesses (PBAs) from 39 centers in 16 countries, focusing on infection causes, risk factors, and mortality outcomes over a 12-year period.
  • Study results showed that the majority of patients were middle-aged men (average age 46.8), with symptoms like headaches and fever; Gram-positive cocci were the most common pathogens.
  • Key factors influencing mortality at 42 days included intravenous drug use and malignancy, while factors affecting 180-day mortality included temporal lobe involvement and the presence of unidentified bacteria.

Listeriosis caused by due to its ability to withstand harsh conditions and form biofilms on post-processed food poses a serious public health issue. It typically manifests itself with fever and gastrointestinal symptoms, but it can escalate with life-threatening conditions, especially in immunocompromised patients, the elderly, oncologically sick, and even pregnant women. The diagnosis is based on blood and cerebrospinal fluid culture growth, but it presents significant challenges due to deceptive findings and low positivity rates, the golden standard includes molecular diagnostic tests such as real-time PCR and metagenomic next-generation sequencing, which offer higher sensitivity and rapid detection.
