AIM: To describe in detail changes in the incidence of invasive pneumococcal disease in the Czech Republic during and after the COVID-19 pandemic. Another objective is molecular analysis of S. pneumoniae isolates of serotypes 3 and 19A recovered in the Czech Republic between 2018 and 2024. MATERIAL AND METHODS: Data on the incidence of invasive pneumococcal disease and S. pneumoniae serotypes were obtained from the invasive pneumococcal disease surveillance program in the Czech Republic. S. pneumoniae isolates of serotypes 3 (63) and 19A (66) from 2018-2024 were subjected to whole genome sequencing (WGS) to characterize the GPSCs (Global Pneumococcal Sequence Clusters) and STs (sequence types) and place them in a global context. RESULTS: Results: During the COVID-19 pandemic, a significant decline was observed in the incidence of invasive pneumococcal disease in the Czech Republic. Following the pandemic, the incidence of invasive pneumococcal disease rose again to significantly higher levels than before the pandemic. Compared to the 2018–2019 period, the incidence of certain serotypes increased in 2023–2024, including vaccine serotypes 3, 4, 14, and 15B, while the incidence of serotypes 8, 12F, and 15A, among others, decreased. Whole genome sequencing analysis demonstrated the dominance of GPSC12 ST-180 among serotype 3 isolates throughout the study period. Among serotype 19A isolates, GPSC4 prevailed, particularly ST-416. CONCLUSIONS: The COVID-19 pandemic has demonstrated how rapidly the epidemiological situation of invasive pneumococcal disease can change and that continuous, systematic surveillance of invasive pneumococcal disease is necessary. The best prevention against invasive pneumococcal disease is vaccination, primarily with higher valency pneumococcal conjugate vaccines.
Electronic Health Record (EHR) systems are now being developed in many places. More advanced systems provide also reminder facilities, usually based on if-then rules. In this paper we propose a method how to build the reminder facility directly upon the guideline interchange format (GLIF) model of medical guidelines. The method compares data items on the input of EHR system with medical guidelines GLIF model and is able to reveal if the input data item, that represents patient diagnosis or proposed patient treatment, contradicts with medical guidelines or not. The reminder facility can be part of EHR system itself or it can be realized by a stand-alone reminder system (SRS). The possible architecture of stand-alone reminder system is described in this paper and the advantages of stand-alone solution are discussed. The part of the EHR system could be also a browser that would present graphical GLIF model in easy to understand manner on the user screen. This browser can be data driven and focus attention of user to the relevant part of medical guidelines GLIF model.
Lilium spp. with symptoms of severe fasciation were observed in Southern and central Bohemia during the period 1999-2003. Nucleic acids extracted from symptomatic and asymptomatic plants were used in nested-PCR assays with primers amplifying 16S-23S rRNA sequences specific for phytoplasmas. The subsequent nested-PCR with phytoplasma group-specific primers followed by RFLP analyses and the 16S ribosomal gene sequencing, allowed classification of the detected phytoplasmas in the aster yellows group, subgroups 16SrI-B and 16SrI-C alone, and in mixed infection. Samples infected by 16SrI-C phytoplasmas showed different overlapping RFLP profiles after TruI digestion of R16F2/R2 amplicons. Two of these amplicons were sequenced, one of them directly and the other after cloning; sequence analyses and blast alignment confirmed the presence of two different overlapping patterns in samples studied. The sequences obtained were closely related, respectively, to operon A and operon B ribosomal sequences of the clover phyllody phytoplasma. Direct PCR followed by RFLP analyses of the tuf gene with two restriction enzymes showed no differences from reference strain of subgroup 16SrI-C. Infection with aster yellows phytoplasmas of 16SrI-B subgroup in asymptomatic lilies cv. Sunray was also detected.
