Fractures of thoracolumbar spine in the field of ankylosing diseases such as ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) can by surgically treated with miniinvasive posterior transpedicular fixation. The exact length of implant is the subject of several studies. In our study, we retrospectively evaluated the treatment of B3 fractures of the ankylosed thoracolumbar spine with use a shorter versus longer implant, always with 8 screws. ⋯ Based on this study, we could conclude that both used constructions are comparable in terms of treatment results. It can be observed that longer fixation is more resistant to kyphotization at 6 and 12 months, but we would need a larger group of patients to confirm this hypothesis. In all incomplete reduced fractures through the surgery, complete reduction after verticalization occurred within 6 months in both groups. The angle of reduction was greater in the group with longer fixation, but the difference was not significant (Tab. 6, Fig. 8, Ref. 31).

Review Comparative Study
A comparative review of coronary computed tomography angiography and myocardial perfusion imaging.
Coronary artery disease remains a leading cause of morbidity and mortality worldwide. Non-invasive imaging techniques have revolutionized the diagnosis and management of coronary artery disease. ⋯ In parallel, we discuss the role of coronary computed tomography angiography and myocardial perfusion imaging in the diagnosis and management of coronary artery disease, their comparative efficacy, and their potential to guide subsequent interventions (Fig. 4, Ref. 70). Keywords: angiography, heart, perfusion, myocardial blood flow, ischemic heart disease.

ASCT has been considered the standard of care for younger patients with NDMM, however, not all the studies published so far have uniformly demonstrated the complete superiority of ASCT over chemotherapy at standard doses. A systematic review and meta-analysis of randomized studies has shown a significant benefit with single ASCT in terms of prolonged progression-free survival (PFS), but not of overall survival (OS). In our retrospective analysis we investigated the impact of high dose (HD) chemotherapy followed by ASCT in special population of patients with high risk cytogenetic profile on the PFS and treatment outcome. ⋯ HD chemotherapy followed by ASCT remains the standard of care for NDMM eligible for high dose chemotherapy. Our results confirm the benefit of ASCT even in the presence of HRCA. Lower PFS in the HRCA subgroup might indicate the need for more intensive treatment, which may be achieved by tandem ASCT defined as two ASCT performed within a period of no more than six months. Additionally, as three- and four-drug induction therapies are becoming increasingly available and effective, resulting in high minimal residual disease (MRD) negative rates, it is important to continue discussing and further personalizing upfront ASCT to avoid overtreatment and possible toxicities especially in the non-high-risk patient population (Tab. 5, Fig. 2, Ref. 9).

Dental caries remains the most prevalent chronic, oral biofilm-associated disease affecting majority of the globe's population in all age categories. Despite enormous and revolutionary progress in omics technologies, it´s aetiology is not fully understood. The interest of current research is primarily focused on the identification and understanding of the crosstalk between main players such as host cell genome, oral microbiome´s genome, factors of immune response, saliva content and nutrition. ⋯ This review focuses on contemporary evidence on genetics factors affecting dental caries and to provide an up-to-date comprehensive description and classification of the genes and their alterations influencing the disease. It also aims to delineate and discuss evidence gaps and potential novel applications of genetics in the context of recent advances (Tab. 2, Ref. 113).

HBeAg-negative chronic HBV infection is defined by viremia < 2,000 IU/ml (or < 20,000 IU/ml), normal ALT activity and minimal liver fibrosis. Some patients do not meet all the criteria and belong to the so-called grey zone. The aim of the work was to analyse a group of patients with asymptomatic chronic HBV infection, divide them according to the levels of HBV DNA during follow-up and to compare the clinical and laboratory parameters of the patients within the groups. ⋯ Patients with HBeAg-negative chronic HBV infection often have fluctuating HBV DNA and ALT values during follow-ups. Statistically significantly higher proportion of abnormal ALT activity in patients with HBV DNA > 2,000 IU/ml may suggest higher risk of adverse outcomes. Initiation of treatment in such patients is not always necessary unless they also meet the other indication criteria for treatment. The exact definition of the grey zone is currently absent (Tab. 2, Fig. 2, Ref. 16).
