RESUMO
We retrospectively assessed the utility of a flow cytometry-based test quantifying the percentage of CD3+ T cells with the CD4-/CD8- phenotype for predicting tularemia diagnoses in 64 probable and confirmed tularemia patients treated during 2003-2015 and 342 controls with tularemia-like illnesses treated during 2012-2015 in the Czech Republic. The median percentage of CD3+/CD4-/CD8- T cells in peripheral blood was higher in tularemia patients (19%, 95% CI 17%-22%) than in controls (3%, 95% CI 2%-3%). When we used 8% as the cutoff, this test's sensitivity was 0.953 and specificity 0.895 for distinguishing cases from controls. The CD3+/CD4-/CD8- T cells increased a median of 7 days before tularemia serologic test results became positive. This test supports early presumptive diagnosis of tularemia for clinically suspected cases 7-14 days before diagnosis can be confirmed by serologic testing in regions with low prevalences of tularemia-like illnesses.

The stability and properties of donor-acceptor adducts of square-planar Pt(II) and Ir(I) complexes (designated as PtX, IrX, or generally MX complexes) with trihydrides and trihalides of group 13 elements of general formula YZ3 (Y = B, Al, Ga; Z = H, F, Cl, Br) were studied theoretically using DFT methodology in the gas phase. MX complexes were represented by wide range of the ligand environment which included model complexes [Ir(NH3)3X]0 and cis-[Pt(NH3)2X2]0 (X = H, CH3, F, Cl, Br) and isoelectronic complexes [Ir(NNN)(CH3)]0 and [Pt(NCN)(CH3)]0 with tridentate NNN and NCN pincer ligands. MX complexes acted as the Lewis bases donating electron density from the doubly occupied 5d z2 atomic orbital of the metal M atom to the empty valence p z orbital of Y whose evidence was clearly provided by the natural atomic orbital (NAO) analysis. This charge transfer led to the formation of pentacoordinated square pyramidal MX·(YZ3) adducts with M·Y dative bond. Binding energies were -44.7 and -75.2 kcal/mol for interaction of GaF3 as the strongest acid with PtNCN and IrNNN pincer ligands complexes. Only M·B bonds had covalent character although MX·BZ3 adducts were the least stable due to large values of Pauli repulsion and deformation energies. The highest degree of covalent character was found for adducts of BH3 in all series of structures studied. Al and Ga adducts showed remarkably similar behavior with respect to geometry and binding energies.
RESUMO
OBJECTIVE: Vancomycin therapeutic drug monitoring (TDM) is recommended for better treatment efficacy and safety. The Scottish Antimicrobial Prescribing Group model recommends weight-based loading dose, next 3-4 doses based on creatinine clearance and maintenance doses according to trough concentrations. METHODS: Retrospective cohort study of all adult patients treated with vancomycin before and after introducing the guideline in a large Czech hospital in 2015 compares the success rate in achieving recommended trough concentrations (10-20 mg/l) during first measurement and efficiency of maintaining these concentrations subsequently. Assessment of vancomycin related nephrotoxicity is included. RESULTS: In 2014, 74/163 (45.4 %) patients achieved recommended concentrations in the first measurement, compared to 101/160 (63.1 %) patients in 2016 (χ2; p = 0.001). Recommended trough concentrations in more than half of subsequent measurements were detected in 51/105 patients (48.6 %) in 2014 and in 80/117 patients (68.4 %) in 2016. Not a single level in subsequent measurements within the range was detected in 28 (26.7 %) cases in 2014 and in 10 (8.5 %) cases in 2016 (Mann-Whitney; p = 0.026). There was no difference in nephropathy occurrence (χ2; p = 0.286). CONCLUSION: The adopted Scottish model of vancomycin TDM resulted in very significantly higher achievement of recommended trough concentrations during first measurements and significantly more effective maintenance of subsequent concentrations, without increased nephrotoxicity. Key words: guideline - therapeutic drug monitoring - vancomycin.

PURPOSE: Sarcopenic obesity (SO) as a new diagnostic entity defined by presence of obesity in combination with sarcopenia represents serious health condition negatively affecting quality of life in old age. Despite the rapidly increasing incidence of SO associated with demographic aging, clear diagnostic criteria for SO have not yet been established. We describe here the applicability of the EWGSOP2 and EWGSOP1 diagnostic criteria in identifying sarcopenia and SO and the development of a refinement algorithm for SO detection. METHODS: In total 156 subjects were pre-screened, 126 had a complete dataset and were included, 20.6% (n = 26) were men and 79.4% (n = 100) women, mean age 81 ± 6.3 years in tertiary hospital, Prague, Czech Republic. Testing of physical performance (hand-grip test, 400 m walk test, chair stand test, gait speed), anthropometric measures and SARC-F, SPPB and MNA-SF were used to determine physical, functional, and nutritional status, while muscle mass and fat mass were measured by DXA scans to confirm sarcopenia and SO diagnosis. RESULTS: The prevalence of sarcopenia (BMI adjusted ALM < 0.789 for men, < 0.512 for women) was 26.2% (n = 33), SO in 20.6% (n = 26). 78.8% of all sarcopenic subjects fulfilled the criteria of SO (FM > 27% for men and > 38% for women; waist circumference > 90 cm for men and > 85 cm for women). EWGSOP1 criteria for diagnosing sarcopenia showed better sensitivity of 97.0% than the EWGSOP2 66.7%, while specificity reached 100% for both criteria. According to DXA measurement, EWGSOP1 identified 3.0% cases (1 out of 33) as false negative meanwhile EWGSOP2 identified 33.3% cases as false negative and this difference was statistically significant (McNemar's test, p < 0.001). An algorithm for SO was developed (which uses sex, BMI, height, waist circumference and SPPB) with sensitivity and specificity of 88.5 and 91.0%, respectively. CONCLUSION: High prevalence of obesity among elderly people and rather low sensitivity of current diagnostic criteria for SO call for ongoing research. Broader international consensus for SO diagnostic criteria, screening and diagnosis algorithm are crucial for early detection of SO in older people in clinical practice so that optimal multi-component therapy can be initiated.

THEORETICAL BASIS: A sedentary lifestyle, consumption of inappropriate food, smoking or alcohol consumption can contribute to the overall deterioration of lifestyle and lead to weight gain. Lifestyle includes nutrition, physical activity, sleep, psychological well-being, good relationships or job satisfaction. We can influence some parts of our lifestyle, but we cannot influence many other factors like genetic predisposition or the environment in which we live. OBJECTIVE OF STUDY: The objective of the study is to evaluate the relationship between lifestyle and BMI (Body Mass Index), as well as differences based on age and sex. METHODOLOGY: A self-constructed questionnaire containing 71 questions was used to determine information about lifestyle. The collected data was based on the assessment of body mass index (BMI) and age, all respondents were measured using the stadiometer and InBody 270. The group included 323 adults (156 men and 167 women) and was divided according to BMI (BMI lower than 25 kg/m2, and BMI of 25 kg/m2 or higher). The selected lifestyle characteristics were grouped to create a positive score including positive lifestyle factors, a negative score including negative lifestyle factors, and an overall healthy lifestyle score that included positive and negative scores. RESULTS: We found out that physiological BMI (18.5-24.9 kg/m2) was more common in respondents with higher education and students. The most respondents prefer omnivorous diet, in lower BMI group were mainly non-smokers and occasional consumers of alcohol, in comparison to higher BMI group where were former smokers and those who abstained from alcohol. All scales of lifestyle are sex-related and negative healthy lifestyle score also depend on BMI. Effect of age is not significant. CONCLUSIONS: According to our study, people with a physiological BMI have a significantly healthier lifestyle compared to overweight or obese people. The overall lifestyle values, as well as the positive and negative lifestyle scores, depend on sex; the negative healthy lifestyle score also depends on BMI.

RESUMO
The kinetics of the hydration reaction on trans-[Pt(NH3)2(pyrX)Cl]+ (pyr = pyridine) complexes (X = OH-, Cl-, F-, Br-, NO2 -, NH2, SH-, CH3, C≡CH, and DMA) was studied by density functional theory calculations in the gas phase and in water solution described by the implicit polarizable continuum model method. All possible positions ortho, meta, and para of the substituent X in the pyridine ring were considered. The substitution of the pyr ligand by electron-donating X's led to the strengthening of the Pt-N1(pyrX) (Pt-NpyrX) bond and the weakening of the trans Pt-Cl or Pt-Ow bonds. The electron-withdrawing X's have exactly the opposite effect. The strengths of these bonds can be predicted from the basicity of sigma electrons on the NpyrX atom determined on the isolated pyrX ligand. As the pyrX ring was oriented perpendicularly with respect to the plane of the complex, the nature of the X···Cl electrostatic interaction was the decisive factor for the transition-state (TS) stabilization which resulted in the highest selectivity of ortho-substituted systems with respect to the reaction rate. Because of a smaller size of X's, the steric effects influenced less importantly the values of activation Gibbs energies ΔG ⧧ but caused geometry changes such as the elongation of the Pt-NpyrX bonds. Substitution in the meta position led to the highest ΔG ⧧ values for most of the X's. The changes of ΔG ⧧ because of electronic effects were the same in the gas phase and the water solvent. However, as the water solvent dampened electrostatic interactions, 2200 and 150 times differences in the reaction rate were observed between the most and the least reactive mono-substituted complexes in the gas phase and the water solvent, respectively. An additional NO2 substitution of the pyrNO2 ligand further decelerated the rate of the hydration reaction, but on the other hand, the poly-NH2 complexes were no more reactive than the fastest o-NH2 system. In the gas phase, the poly-X complexes showed the additivity of the substituent effects with respect to the Pt-ligand bond strengths and the ligand charges.
RESUMO
A cross-sectional survey was undertaken to estimate the prevalence of child maltreatment and adverse childhood experiences in the Czech Republic, as data on these is scarce. The survey was conducted among 1760 randomly selected students from five Czech universities. Participants filled in the adverse childhood experiences survey instrument. The results showed that the prevalence of child maltreatment and other adverse childhood experiences is high: emotional abuse was reported by 20.7%, physical abuse by 17.1%, sexual abuse by 6.4%, and physical neglect by 8.0%. Household dysfunction was also high, with household street drug use reported by 4.9%, alcohol misuse by 15.3%, mental disorder by 13.4%, parental violence by 22.1% and parental separation by 23%. Thirty-eight per cent had not experienced any adverse childhood experience, while 9.9% reported experiencing four or more types of adverse childhood experiences. There was a significant association between adverse childhood experiences and health-harming behaviours such as suicide attempt, drug use, risky sexual behaviour and tobacco use. The findings suggest that there is a need to invest in prevention programmes.

BACKGROUND: Spinal muscular atrophy is a rare hereditary neuromuscular disorder (with a prevalence of 1 per 30,000) that greatly debilitates patients and, in most cases, shortens their life expectancy. Although there is no causal therapy, improvements in symptomatic therapy have extended patients' life expectancy and increased their quality of life. Unfortunately, the advancements in care vary from country to country. To improve the care for children with spinal muscular atrophy in the Czech Republic, we created a survey to obtain the baseline information about their quality of life and compared the data with equivalent data from the United States. METHODS: We used the Pediatric Quality of Life Inventory 3.0 Neuromuscular Measurement Model, which is a health-related quality of life questionnaire specific to children with neuromuscular disorders. The survey was conducted on 35 children with genetically proven spinal muscular atrophy and their parents. RESULTS: Compared with the US data, the Czech data generally show a lower quality of life, mainly in the family resources part. The greatest score was achieved in the section about communication. Altogether, the parents' scores are lower than those of the children. CONCLUSION: In the Czech Republic, patients with spinal muscular atrophy and, especially their parents, have a significantly lower quality of life compared with US patients, mostly because of economic factors and a lack of social support. Our results reveal areas toward which improvement should be directed. The need for family support through social care as well as civic, patient, or organizational support is accentuated.
