Surgery is associated with alterations of alarmins' and related molecules' levels. The aim of this study was to investigate which biomarkers are most involved in surgery. The studied group consisted of 58 patients with inguinal or umbilical hernia or cholecystolithiasis and 21 healthy controls for compa-rison. We also added seven acute patients with appendicitis, cholecystitis and incarcerated hernia. Serum concentrations of soluble receptor of advanced glycation end-products (sRAGE), extracellular newly identified receptor for advanced glycation end-products binding protein (EN-RAGE), calprotectin, high mobility group box 1 (HMGB1) and interleukin 6 (IL-6) were analysed by ELISA before and after surgery. Preoperative concentrations of calprotectin were significantly decreased while concentrations of sRAGE were significantly increased in patients compared to controls; the concentrations of EN-RAGE and HMGB1 did not differ significantly. IL-6 levels were undetectable in elective patients preoperatively and in controls. Postoperatively, there was a significant increase of EN-RAGE, calprotectin, HMGB1, and IL-6 and a significant decrease of sRAGE compared to preoperative levels. In acute patients, all tested molecules except for sRAGE were significantly increased preoperatively, and sRAGE was significantly decreased. In contrast, after surgery, we could observe a further increase in IL-6; the other biomarkers did not differ significantly. We can conclude that the concentrations of all tested biomarkers are significantly influenced by elective surgery. The postoperative levels of all tested molecules increase except for sRAGE, whose level is significantly decreased after surgery. In acute states, these molecules are already increased, and the influence of surgery is, apart from IL-6, insignificant.

In forensic contexts, sternal anatomical varieties represent useful tools for the identification of an individual, either by comparison of ante-mortem and post-mortem data, or by potential comparison of data from biologically related individuals. Sternal body variation is also used to detect the biological affinity of individuals in bioarchaeology. However, no study has been made available to date on the degree to which the overall shape of the sternal body reflects the degree of biological relatedness. We, therefore, analyzed the sternal body shape of 10 individuals with known genealogical data, members of one family over three generations including inbred individuals (19th-20th centuries, Bohemia, Czech Republic), and a control sample of 12 biologically unrelated individuals. First, closely biologically related individuals were compared with unrelated individuals based on 10 variables expressing the morphological characteristics of the sternum, and then all individuals were compared based on Fourier analysis depending on their degree of relationship. The results showed that there is a greater degree of shape similarity in biologically related individuals than in unrelated individuals, and variability decreases with an increasing degree of relatedness. Inbred individuals showed the lowest sternum-shape distances and degree of variability, while unrelated individuals, showed the highest distances and variability. Moreover, in some cases, the documented relationships were also supported by a similar morphology of the ossified and fused xiphoid process. Thus, sternal shape analysis expands the possibilities for individual identification and the detection of the biological affinity of individuals for both the forensic sciences and bioarchaeology.

Immunotherapy has dramatically influenced and changed therapeutical approach in non-small cell lung cancer (NSCLC) in recent five years. Even though we can reach long-term response to this treatment in approximately 20% of patients with NSCLC, we are still not able to identify this cohort of patients based on predictive biomarkers. In our study we have focused on tumor mutation burden (TMB), one of the potential biomarkers which could predict effectiveness of check-point inhibitors, but has several limitations, especially in multiple approaches to TMB quantification and ununiform threshold. We determined the value of TMB in tumor tissue (tTMB) and blood (bTMB) in 20 patients with early stage NSCLC using original custom gene panel LMB_TMB1. We evaluated various possibilities of TMB calculation and concluded that TMB should be counted from both somatic non-synonymous and synonymous mutations. Considering various factors, we established cut-offs of tTMB in/excluding HLA genes as ≥22 mut/Mb and 12 mut/Mb respectively, and cut-offs of bTMB were defined as ≥21 mut/Mb and ≥5 mut/Mb, respectively. We also observed trend in correlation of somatic mutations in HLA genes with overall survival of patients.

PURPOSE: The main aim was to evaluate the changes in beliefs about immunosuppressants over a 3-year period in patients after kidney transplantation. The second aim was to investigate the relationship between beliefs, medication adherence, and selected clinical outcomes such as graft functioning. PATIENTS AND METHODS: This observational follow-up study was conducted in the outpatient post-transplant clinic at the University Hospital Hradec Kralove in the Czech Republic. Adult patients, at least 4 weeks after kidney transplantation, were invited for the structured interview, which was followed by a self-administered questionnaire survey during their regularly scheduled visits at the clinic. Appropriate paired tests were used to compare two measurements of beliefs about immunosuppressants by BMQ-CZ© in 2016 (baseline) and in 2019 (follow-up). Self-reported adherence was measured by two validated tools (MARS-CZ© and BAASIS©) capturing implementation and discontinuation phases. A generalized linear model was used to investigate the relation between beliefs and the consecutive estimated glomerular filtration rate. RESULTS: The study involved 134 patients. Over time, their perceived treatment necessity beliefs of immunosuppressants decreased, while their treatment-related concerns increased. Overall self-reported non-adherence (ie, taking, dosing and discontinuation of immunosuppressants) was reported by 12% of the patients in both observation periods. In the follow-up period, timing non-adherence was reported by 52 (38.8%) patients. Higher baseline treatment concerns were associated with poor adherence whereas higher baseline treatment necessity beliefs corresponded with better kidney functioning, even after adjusting for age. CONCLUSION: Higher treatment necessity beliefs corresponded with better kidney functioning, whereas higher treatment concerns were related to non-adherence to immunosuppressants at the beginning of the observed period. Still, most patients accepted their medicines that do not come without risk. Nevertheless, decreasing treatment necessity beliefs on one hand, and increasing treatment concerns on the other, should be considered in clinical practice.

Background Geriatric patients represent a vulnerable population in terms of adverse drug events (ADEs). Objective The aims of this study were to determine the prevalence and preventability of hospital admissions to a geriatric ward related to ADEs, to identify medications involved in these ADEs and to describe potential preventability aspects of ADE-related admissions. Setting University Hospital Hradec Králové, Czech Republic. Methods This cross-sectional study evaluated acute hospital admissions to the geriatric ward of University Hospital Hradec Králové over a period of nine months (April-December 2017). Medication reviews were performed in order to identify ADE-related hospital admissions. Causality was assessed using the World Health Organization-Uppsala Monitoring Centre criteria. Modified Schumock-Thornton algorithm was used to assess the preventability of ADEs. Main outcome measure 9-month-prevalence of ADE-related hospital admissions. Results A total of 366 hospital admissions were included. The 9-month-prevalence of ADE-related hospital admissions was 11.75% [95% confidence interval 8.45-15.05]. Antithrombotic agents and diuretics represented the most common medication classes associated with ADEs (30.2% each). Electrolyte disturbances and gastrointestinal haemorrhages and ulcerations were the most frequently observed ADEs associated with hospital admission. Out of 43 ADE-related hospitalisations, 23 (53.5%) were considered potentially preventable. Conclusion The contribution of ADEs to hospital admission to the geriatric ward was not negligible. Our results also suggest that 53.5% of identified ADE-related admissions could be potentially prevented. This finding demonstrates just how important the research on the preventability of medication-related hospitalisations is. Further studies and implementations are still needed aiming to minimize the risk of medication-related harm.

Background Oral anticoagulants are established drugs of choice for the prevention and treatment of thromboembolic events. However, monitoring their safety remains warranted. Objective The aim was to analyze spontaneous reports of adverse drug reactions related to oral anticoagulants in the Czech Republic. Setting Retrospective observational pharmacovigilance study. Methods Adverse drug reaction reports were obtained from the State Institute for Drug Control between January 2005 and November 2017. Reports related to warfarin, dabigatran, apixaban, and rivaroxaban received from healthcare professionals and patients were analyzed. Main outcome measure Frequency and nature of adverse drug reactions reported to oral anticoagulants. Results In total, 297 reports containing 672 adverse drug reactions were received; 269 reports were sent by healthcare professionals (85% by physicians). In 65% of all reports, reactions were due to direct oral anticoagulants. A higher total number of adverse drug reactions was associated with direct oral anticoagulants than with warfarin [reporting odds ratio (ROR): 10.76; confidence interval (CI): 8.70-13.32; p < 0.001]. Along with the increasing utilization of direct oral anticoagulants, the reporting rate gradually declined over time, especially for rivaroxaban and apixaban. Fatal outcomes were reported in 7%, mostly for dabigatran. Hemorrhagic reactions were the most frequently reported adverse drug reactions (37% associated with dabigatran, 28% with apixaban, 24% with warfarin, and 23% with rivaroxaban), and compared to warfarin, they were significantly more often associated with direct oral anticoagulants (ROR: 14.36; CI: 9.57-21.54; p < 0.001). Conclusion The number of adverse drug reaction reports related to oral anticoagulants in the Czech Republic was relatively low, compared to other studies, but 96% of the cases were serious. Data from spontaneous adverse drug reactions reporting should be further analyzed in order to obtain additional information on the safety profile of oral anticoagulants.

RATIONALE, AIMS, AND OBJECTIVES: Falls are among the major problems occurring in hospital setting, when drugs are viewed as important modifiable risk factor of falling. The aim was to analyse the effect of pharmacotherapy on the risk of falls in hospitalized patients. METHODS: A multicentre prospective case-control study was conducted in 2017 retrieving data from four hospitals in South Bohemia, Czech Republic. An online database was constructed to collect patient and fall-related data. Each fall that occurred during hospitalization was assigned to appropriate controls (no fall during hospitalization) based on gender, age, length of hospitalization, and the number of drugs. Univariate and multivariate correlations were performed with a significance level of P < .05. RESULTS: A total of 222 fall cases (107 males; median age, 81 y) and 1076 controls (516 males; median age, 80 y) were included. According to the first ATC level classification, drugs from groups S, N, and P were significantly associated with fall-related risk compared with controls (P < .05); further analysis of ATC levels showed that only psycholeptics (N05), antipsychotics (N05A), and tiapride were significantly associated with falls. Regression analysis revealed use of psycholeptics N05 (OR = 2.06; 95% CI, 1.56-2.76), or ophthalmologicals S01 (OR = 2.72; 95% CI, 1.37-5.41), as factors with the highest fall-related risk. CONCLUSIONS: Apart from the commonly considered fall-risk increasing drugs, other groups, such as ophthalmologicals, should also be considered; however, regarding clinical practice, it is difficult to evaluate the effects of individual drugs in the context of other risk factors of falls, due to the multifactorial nature of falls.

This study aimed to analyze the effect of fall risk-increasing drugs (FRIDs) and drug-related factors relative to falls through clinical pharmacy service in hospitalized patients, focusing on the relevance of clinical pharmacist evaluation in the context of physician assessment. A prospective study of inpatient falls was conducted in 2017 retrieving data from 4 hospitals in South Bohemia, Czech Republic. An online database was developed to collect patient and fall-related data, and fall evaluation records. Healthcare professionals classified the overall effect of drugs on falls using Likert scale. Univariate and multivariate correlations were performed with a significance level of p < 0.05. Out of the total 280 falls (mean age of patients 77.0 years), a mean of 2.8 diagnoses with fall-related risk, 8.8 drugs, and 4.1 FRIDs per fall were identified. Incidence of falls decreased quarterly (p < 0.001). Use of FRIDs were positively associated with increasing age (p = 0.007). Clinical pharmacists were more likely to identify pharmacotherapy as the relevant fall-related risk, compared to physicians evaluation (p < 0.001). An increasing total number of prescribed drugs as well as higher number of FRIDs increased the suspicion in both professionals in the context of drug-related causes of falls.

PURPOSE: Kidney transplant (KTx) recipients should strictly adhere to their lifelong complex therapeutic regimen, and any barriers to medication adherence can weaken correct patient behavior. This study aimed to determine the adherence to immunosuppressive therapy (IS) in KTx adult outpatients in the Czech Republic, and attempted to gain a greater insight into their attitudes toward IS and self-management tasks. MATERIALS AND METHODS: Pharmacist-led structured interviews were conducted to assess self-reported adherence to IS using the Czech version of the Medication Adherence Report Scale, in the context of attitudes toward IS in terms of necessity and concern scale of the Beliefs about Medicines Questionnaire. A specific questionnaire was developed to target IS self-management tasks. Medication records were also reviewed for IS serum levels, reflecting direct adherence measurement. Descriptive statistics were used to calculate adherence and self-management variables, and were analyzed by univariate and multivariate correlations, including the decision-tree method. RESULTS: The interview was completed by 211 (male 123; mean age 55.0±12.4 years, mean time 6.6±5.9 years after KTx) of the total of 235 patients. Full adherence to IS was reported by 173 (82.0%) patients. Most of them had IS serum levels within the therapeutic range, however, cyclosporine was associated with the highest variability (P<0.001). Non-adherence and concerns increased over time after KTx (P<0.05). Despite the more common unintentional non-adherence (P<0.001), relatively high concerns signified the risk of not taking IS as prescribed. Concerns also correlated with the perception of impaired health status (P<0.01), as well as the occurrence of IS-related adverse effects (P<0.001). The patients' awareness of their therapy was insufficient, and main gaps in self-management comprised inadequate sun protection, incorrect administration of IS, and unfamiliarity with the IS name, or their indications. CONCLUSION: Although self-reported adherence to IS therapy was satisfactory, the comprehensive evaluation enabled the detection of greater concerns about IS, as well as underestimated self-management tasks that posttransplant interventions should target in the future.

Three peat cores were extracted from the Kovářská Bog in the central Ore Mountains to study anthropogenic pollution generated by mining and metallurgy. The core profiles were 14C dated, and concentrations of selected elements were determined by ICP MS and HG-AAS. Principal component analysis indicated that Pb, Cu, As and Ag may be useful elements for the reconstruction of historical atmospheric pollution. Total and anthropogenic accumulation rates (ARs) of Pb, Cu and As estimated for the last ca. 3500years showed similar chronologies, and revealed twelve periods of elevated ARs of Pb, As and Cu related to possible mining and metallurgic activities. In total, four periods of elevated ARs of Pb, Cu and As were detected during the Middle and Late Bronze Ages, including a distinct Late Bronze Age pollution event between 1030BCE and 910BCE. The Iron Age included three episodes of increased ARs of Pb and As; the first and the most distinctive episode, recorded between 730 and 440BCE, was simultaneous with the Bylany culture during the Hallstatt Period. The Roman Age was characterized by one pollution event, two events were detected in the Middle Ages, and the last two during the modern period. Enhanced element ARs in the late 12th and 15th centuries clearly documented the onset of two periods of intense mining in the Ore Mountains. Metal ARs culminated in ca. 1600CE, and subsequently decreased after the beginning of the Thirty Years' War. The last boom of mining between 1700CE and 1830CE represented the last period of important metallurgical operations. Late Medieval and modern period metal ARs are in good agreement with written documents. Earlier pollution peaks suggest that local metal production could have a much longer tradition than commonly believed; however, archaeological or written evidence is scarce or lacking.
