Construct: The Knowledge of Malnutrition - Geriatric 2.0' (KoM-G 2.0) instrument was designed to quantify nursing staff malnutrition knowledge in inpatient medical and rehabilitation care facilities, as well as home health care. It has been used to assess grasp of current clinical practice guidelines and proficiency in addressing issues related to malnutrition. It provides insight into familiarity with and capacity to tackle issues pertaining to malnutrition in clinical practice. Furthermore, it has been used assess the effectiveness of educational interventions aimed at improving nursing professionals knowledge and awareness of malnutrition. Background: The quality of nursing education affects malnutrition risk assessment, monitoring of food intake, and effectiveness of nutrition care. Improvements in malnutrition education require determining the current level of knowledge and benchmarking with other countries. In the Czech Republic, no nationwide assessment of nursing staff malnutrition knowledge has ever been conducted. Approach: The purpose of the study was to translate the KoM-G 2.0 instrument, gather initial validity evidence, and evaluate nursing staff knowledge of malnutrition in inpatient medical, rehabilitation care facilities, and home care in the Czech Republic. All inpatient healthcare facilities and home healthcare facilities in the Czech Republic were invited to participate. The Czech version of the internationally standardized KoM-G 2.0 (KoM-G 2.0 CZ) was used to assess nursing staff malnutrition knowledge between 3 February 2021 and 31 May 2021. A total of 728 nurses began the questionnaire, and 465 (63.9%) of respondents completed it and were included in the study. Data analyses examined instrument difficulty, discriminability, and reliability, as well as sources of variation in knowledge scores. Findings: The psychometric characteristics of the KoM-G 2.0 CZ instrument included the difficulty index Q (0.61), the discriminant index (ULI 0.29, RIT 0.38, upper-lower 30% 0.67), and Cronbach alpha (0.619). The overall mean of correct answers was 6.24 (SD 2.8). There was a significant impact of educational attainment and nutrition training on KoM-G 2.0 CZ scores. Conclusions: Our findings provide initial validity evidence that KoM-G 2.0 CZ is useful and appropriate for assessing malnutrition knowledge among Czech nursing staff. Our research identified gaps in knowledge and examples of good practice in understanding malnutrition that can be applied internationally. The knowledge of academic nurses was greater; therefore, we suggest they play a key role in nutritional care. We recommend continuous education to improve understanding of malnutrition in this setting.

The past 30 years have brought undeniable progress in medicine, biology, physics, and research. Knowledge of the nature of the human body, diseases, and disorders has been constantly improving, and the same is true regarding their treatment and diagnosis. One of the greatest advances in recent years has been the introduction of nanoparticles (NPs) into medicine. NPs refer to a material at a nanometer scale (0.1-100 nm) with features (specific physical, chemical, and biological properties) that are broadly and increasingly used in the medical field. Their applications in cancer treatment and radiotherapy seem particularly attractive. In this field, inorganic/metal NPs with high atomic number Z have been employed mainly due to their ability to enhance ionizing radiation's photoelectric and Compton effects and thereby increase conventional radiation therapy's efficacy. The improvement NPs enable relates to their enhanced permeation ability and longer retention effect in tumor cells, capacity to reduce toxicity of commercially available cancer drugs through advanced NPs drug delivery systems, radiation sensitizers of tumors, or enhancers of radiation doses to tumors. Advanced options according to size, core, and surface modification allow even such multimodal approaches in therapy as nanotheranostics or combined treatments. The current state of knowledge emphasizes the role of gold nanoparticles (AuNPs) in sensitizing tumors to radiation. We have reviewed AuNPs and their radiosensitizing power during radiation treatment. Our results are divided into groups based on AuNPs' surface modification and/or core structure design. This study provides a complete summary of the in vivo sensitizing effect of AuNPs, surface-modified AuNPs, and AuNPs combined with different elements, providing evidence for further successful veterinarian and clinical implementation.

It is necessary for nursing staff to have adequate knowledge of malnutrition in older people in order to provide high quality care. This study was conducted to update the Knowledge of Malnutrition-Geriatric (KoM-G) questionnaire to fit different settings and to cross-culturally adapt it to the German, Czech, Dutch and Turkish languages. In Part 1 of the study, the KoM-G questionnaire was updated and adapted for use in different settings. Content validation of the KoM-G 2.0 was carried out in a Delphi study with 16 experts. The final KoM-G 2.0 questionnaire consists of 16 items with a Scale Content Validity Index/Average of 94.5%. In Part 2, the English KoM-G 2.0 was cross-culturally adapted into the German, Czech, Dutch and Turkish languages. In the pilot test, between 96.9% (The Netherlands) and 97.8% (Austria) of the nursing staff rated the items as understandable. The KoM-G 2.0 is an up-to-date questionnaire with a highly satisfactory Content Validity Index. It was cross-culturally adapted into the German, Czech, Dutch, and Turkish languages, and the understandability was high. At the moment, the necessary comprehensive psychometric testing of the KoM-G 2.0 is in process. Afterwards it can be used to compare nurses' knowledge between various countries and settings.

BACKGROUND: Nursing staff must have sufficient knowledge in order to adequately prevent and treat malnutrition. However, only a marginal amount of information on this topic is available in the literature. OBJECTIVES: This paper provides a comparison of the malnutrition knowledge among nursing staff in Austria, the Czech Republic, the Netherlands, and Turkey and presents factors associated with the malnutrition knowledge of nursing staff. DESIGN: A cross-sectional study was performed. SETTING AND PARTICIPANTS: Nursing staff from different care settings in Austria, the Czech Republic, the Netherlands, and Turkey participated in the study. METHODS: The KoM-G 2.0 (Knowledge of Malnutrition - Geriatric) questionnaire was used for data collection. RESULTS: In total, 2056 participants from different care settings took part in the study. Between 11.7 % (Turkey) and 32.5 % (Austria) of the participants had high levels of malnutrition knowledge. The country itself was the factor most strongly associated with malnutrition knowledge. The nurses' educational level and specialised training of nursing staff were also significantly (p < 0.001) associated with malnutrition knowledge. Questions about "factors that should be considered during older persons' food intake" were most frequently answered correctly, while questions about "different aspects of nutritional screening" were less often answered correctly in all four countries. CONCLUSIONS: This study was one of the first to describe the rather low level of malnutrition knowledge among nursing staff in different countries. The country itself was identified as the factor most strongly associated with the nurses' knowledge of malnutrition, while the nursing staff's basic education as well as further training were also detected as significant factors. These results indicate that it is necessary to extend and improve (academic) nursing education and to offer specialised training programmes which may improve nutritional care across country borders over the long run.

AIMS AND OBJECTIVES: The aim of this study was to find tools for screening the risk of malnutrition in adult hospitalised patients, evaluate their key characteristics including selected psychometric properties and propose the most appropriate tools for nursing practice. BACKGROUND: A large number of existing tools for nutritional screening make it difficult to be aware of all the possibilities and especially to select the optimal tool. DESIGN: The research methodology was designed as secondary research using a scoping review search to map and compare existing tools for assessing the risk of malnutrition in hospitalised adults. METHODS: The analysis focused on the selected psychometric properties of the instruments (sensitivity, specificity, positive and negative predictive value) and key characteristics relevant to the selection of an appropriate instrument. This study follows the PRISMA-ScR Checklist. RESULTS: The review included 27 publications containing 17 tools. The best sensitivity (57%-100%) and specificity (76%-96%) were achieved by the Malnutrition Universal Screening Tool (MUST) and the Nutritional Risk Screening 2002 (NRS 2002). Minimal Eating Observation and Nutrition Form-Version II (MEONF-II) has solid sensitivity (up to 73%), specificity (88%) and high positive predictive values (81%-82%). CONCLUSIONS: The MUST, NRS 2002 and MEONF-II showed satisfactory psychometric properties. MEONF-II and MUST are able to assess risk without weighing the patient. The Hand Grip Strength (HGS) assessment can be recommended to detect reductions in muscle strength. RELEVANCE TO CLINICAL PRACTICE: We recommend the MUST, NRS 2002 and MEONF-II tools for use in clinical practice, as they have the best psychometric properties and are user-friendly. The HGS, which proved to be related to the length of hospital stay (LOS) and used as an indicator of protein-energy malnutrition in obese patients, may be a useful complementary tool. For nursing practice, we recommend selecting a tool with respect to the specifics of a particular workplace.

The dramatic rise in diagnostic procedures, radioisotope-based scans and intervention procedures has created a very valid concern regarding the long-term biological consequences from exposure to low doses of ionizing radiation. Despite its unambiguous medical benefits, additional knowledge on the health outcome of its use is essential. This review summarizes the available information regarding the biological consequences of low-dose radiation (LDR) exposure in humans (e.g. cytogenetic changes, cancer risk and radiation-induced cataracts. However, LDR studies remain relatively new and thus an encompassing view of its biological effects and relevant mechanisms in the human body is still needed.

An online method involving transient electrokinetic dosing and ITP with neutralization reaction boundary (NRB) and/or carrier ampholyte-free isoelectric focusing (CAF IEF) was developed for the preconcentration, preseparation, and analytical determination of glyphosate in aqueous samples containing low concentrations of the analyte of interest. Various parameters were investigated in the framework of an optimization study with the aim of achieving the maximum concentration limit of detection (cLOD) decrease in minimum time. The proposed method used CAF IEF and/or ITP with NRB. The sample was dosed to the column on the stationary reaction boundary (CAF IEF) and/or moving reaction boundary (ITP with NRB), whereat a sharp pH step exists. Here, charge reversal was due to the ampholytes, and/or acid accumulation occurred because of charge loss. Similarly, the accumulated sample was mobilized with TE and analyzed using classical ITP in the second analytical column. Glyphosate (GLY), the analyte of interest, was chosen as a model substance for ITP with NRB and preconcentration as well as focusing preconcentration and CAF IEF using the asymmetric purpose-built NRB. On one side of the asymmetric boundary was the zone of acidic pH; while the opposite side comprised a neutral/basic non-conductive zone of the ampholyte-in this case, GLY. Such an arrangement enables the use of a lower pH on the acidic side, which allows the focusing of strongly acidic ampholytes and the accumulation of weak acids. The electrolyte composition and the dosing time were optimized, and a 14-fold accumulation was achieved in 25 min compared to that by classical ITP and a 180-fold accumulation was achieved through CAF IEF and preconcentration with a glyphosate sample. Both methods are simple and can be conducted using all commercial ITP systems.

INTRODUCTION: Periprocedural stroke represents a rare but serious complication of cardiac catheterization. Pooled data from randomized trials evaluating the risk of stroke following cardiac catheterization via transradial versus transfemoral access showed no difference. On the other hand, a significant difference in stroke rates favoring transradial access was found in a recent meta-analysis of observational studies. Our aim was to determine if there is a difference in stroke risk after transradial versus transfemoral catheterization within a contemporary real-world registry. METHODS: Data from 14,139 patients included in a single-center prospective registry between 2009 and 2016 were used to determine the odds of periprocedural transient ischemic attack (TIA) and stroke for radial versus femoral catheterization via multivariate logistic regression with Firth's correction. RESULTS: A total of 10,931 patients underwent transradial and 3,208 underwent transfemoral catheterization. Periprocedural TIA/stroke occurred in 41 (0.29%) patients. Age was the only significant predictor of TIA/stroke in multivariate analysis, with each additional year representing an odds ratio (OR) = 1.09 (CI 1.05-1.13, p < 0.000). The choice of accession site had no impact on the risk of periprocedural TIA/stroke (OR = 0.81; CI 0.38-1.72, p = 0.577). CONCLUSION: Observational data from a large prospective registry indicate that accession site has no influence on the risk of periprocedural TIA/stroke after cardiac catheterization.

A capillary electroseparation technique for focusing and selective pre-concentration of metal chelates with subsequent on-line isotachophoresis (ITP) analysis was developed and verified. The ions of alkali earth metals (Mg, Ca, Sr, and Ba) were pre-concentrated from the mixture and analyzed. The focusing of the metals was carried out in a ligand step gradient, which was created by the addition of a convenient ligand agent to the regular stationary pH step gradient. The analytical procedure consisted of three steps. During the first step, the metal ions were electrokinetically continuously dosed into the column where they were selectively trapped on the stationary ligand step gradient in the form of unmoving zones of chelate complexes with effectively zero charge. After a detectable amount of analyte was accumulated, the dosing was stopped. The accumulated zones were mobilized to the analytical column, where they were analyzed by the ITP method with conductivity or photometric detection. The proper electrolyte systems for dosing, mobilizing, and analyzing in isoelectric focusing (IEF), moving boundary electrophoresis (MBE), and ITP modes were consequently developed and put into practice. The trapping selectivity can be regulated by the choice of pH and convenient complexing agents. A mixture of alkali earth metals were used as model analytes. Using a 3000 s dosing time, the proposed method improved the detection limit by 5-29 times in comparison to analysis by ITP with classical injection.

The use of carrier ampholyte-free IEF (CAF-IEF) with ITP mobilization and conductivity detection in ITP mode for preconcentration and analysis of amino acids is demonstrated. The analytical procedure consists of three subsequent steps. In the first step, amino acids are continuously dosed from an infinite volume reservoir by electromigration to the column, where a sharp, stationary neutralization reaction boundary (NRB) is created in between acidic and basic primary electrolyte. Here, amino acids are selectively focused (trapped), if their pI falls to the pH difference on both sides of the NRB (pH gap). Amino acids create sharp rectangular zones, arranged according to their pI values. In the second step, focused zones are mobilized. After accumulation of the detectable amount of amino acids, dosing electrolyte in the infinite volume reservoir is changed for the mobilizing electrolyte. The migration mode is changed from CAF-IEF to ITP and substances start to migrate toward the analytical capillary. In the third step, analytes are transferred into the analytical column equipped with a conductivity detector and are detected in the new leading electrolyte in an ITP migration mode. The presented CAF-IEF-ITP-ITP with time-dependent accumulation of the large-volume sample enables to achieve in a reasonable time a 100 times lower c-LOD (here in orders of nmol/L), than can be reached by conventional hyphenated ITP-ITP.
