Abstract
The associations between individual components of metabolic syndrome (MetS) and bone health in children are complex, and data on this topic are sparse and inconsistent. We assessed the relationship between bone turnover markers and markers of the processes underlying MetS (insulin resistance and inflammation) in a group of presumably healthy children aged 9–11 years: 89 (51 girls, 38 boys) presenting without any features of MetS and 26 (10 girls, 16 boys) with central obesity and two features of MetS. Concentrations of glucose, triglycerides (TG), HDL cholesterol (HDL-C), C-reactive protein (CRP), HbA1c, total 25-hydroxyvitamin D (25(OH)D), intact-P1NP (N-terminal propeptide of type I procollagen), CTX-1 (C-terminal telopeptide of type I collagen) were assayed and insulin resistance was assessed (HOMA-IR). BMI centile, waist circumference (WC) and blood pressure were measured. The presence of MetS in girls resulted in significantly lower concentrations of CTX-1 and a trend to lower CTX-1 in boys. The concentrations of bone formation marker i-P1NP were not affected. Among the features associated with MetS, HOMA-IR appeared as the best positive predictor of MetS in girls, whereas CRP was the best positive predictor in boys. A significant influence of HOMA-IR on the decrease in CTX-1 in girls was independent of BMI centile and WC, and the OR of having CTX-1 below the median was 2.8-fold higher/1SD increased in HOMA-IR (p = 0.003). A weak relationship between CTX-1 and CRP was demonstrated in girls (r = −0.233; p = 0.070). Although TG, as a MetS component, was the best significant predictor of MetS in both sexes, there were no correlations between bone markers and TG. We suggest that dyslipidemia is not associated with the levels of bone markers in prepubertal children whereas CRP is weakly related to bone resorption in girls. In prepubertal girls, insulin resistance exerts a dominant negative impact on bone resorption, independent of BMI centile and waist circumference.

Abstract
AIM Impaired regulation of glucose metabolism in childhood adversely affects bone health. We assessed the effect of fasting hyperglycemia and insulin resistance on bone turnover markers in prepubertal children with normal glycemia (<100 mg/dL) and fasting hyperglycemia (100-125 mg/dL). METHODS Glucose, hemoglobin A1c, IGF-I (insulin-like growth factor I), iP1NP (N-terminal propeptide of type I procollagen), CTX-1 (C-terminal telopeptide of type I collagen) and insulin were measured. Bone turnover index (BTI) and HOMA-IR (homeostasis model assessment) were calculated. RESULTS Bone resorption marker (CTX) levels were decreased by 26.5% in boys with hyperglycemia, though only 7% in girls. Hyperglycemia had no effect on the bone formation marker iP1NP. IGF-1, the best predictor of bone marker variance accounted for 25% of iP1NP and 5% of CTX variance. Girls presented significantly higher BTI indicating the predominance of bone formation over resorption. Insulin resistance significantly decreased CTX. In girls, HOMA-IR and IGF-1 predicted 15% of CTX variance. CONSLUSIONS Fasting hyperglycemia and insulin resistance in children impact bone turnover suppressing bone resorption. Hyperglycemia decreased resorption, particularly in boys, while suppression of resorption by insulin resistance was more pronounced in girls. We suggest that the progression of disturbances accompanying prediabetes, may interfere with bone modelling and be deleterious to bone quality in later life.

Abstract
Both vitamin D and insulin-like growth factor 1 (IGF-1) play essential roles in bone metabolism and may interact during prepubertal bone accrual. We investigated the association of low serum 25-hydroxyvitamin D (25(OH)D) (<20 ng/mL) with the circulating bone turnover markers, when compared to their interaction with IGF-1. Subjects and Methods: Serum 25(OH)D, IGF-I, P1NP (N-terminal propeptide of type I procollagen), and CTX-1 (C-terminal telopeptide of type I collagen) were measured, and the bone turnover index (BTI) was calculated in 128 healthy children, aged 9–11 years. Results: Mean 25(OH)D concentration was 21.9 ± 4.9 ng/mL, but in 30.5% of participants it was <20 ng/mL (<50 nmol/L). We observed a trend for higher P1NP (p < 0.05) and IGF-1 (p = 0.08), towards lower 25(OH)D in tertiles. Levels of P1NP in the lowest 25(OH)D tertile (<20 ng/mL) were the highest, while CTX and BTI remained unchanged. Additionally, 25(OH)D negatively correlated with IGF-1, while the correlation with P1NP was not significant. A strong positive correlation of IGF-1 with P1NP and BTI but weak with CTX was observed. Low 25(OH)D (<20 ng/mL) explained 15% of the IGF-1 variance and 6% of the P1NP variance. Conclusions: Low levels of 25(OH)D do not unfavorably alter bone turnover. It seems that serum 25(OH)D level may not be an adequate predictor of bone turnover in children.

Abstract
OBJECTIVES There are many mobile health applications (apps) now available and some that use in some way laboratory medicine data. Among them, patient-oriented are of the lowest content quality. The aim of this study was to compare the opinions of non-laboratory medicine professionals (NLMP) with those of laboratory medicine specialists (LMS) and define the benchmarks for quality assessment of laboratory medicine apps. METHODS Twenty-five volunteers from six European countries evaluated 16 selected patient-oriented apps. Participants were 20-60 years old, 44% were females, with different educational degrees, and no professional involvement in laboratory medicine. Each participant completed a questionnaire based on the Mobile Application Rating Scale (MARS) and the System Usability Scale, as previously used for rating the app quality by LMS. The responses from the two groups were compared using the Mann-Whitney U test and Spearman correlation. RESULTS The median total score of NLMP app evaluation was 2.73 out of 5 (IQR 0.95) compared to 3.78 (IQR 1.05) by the LMS. All scores were statistically significantly lower in the NLMP group (p<0.05), except for the item Information quality (p=0.1631). The suggested benchmarks for a useful appear: increasing awareness of the importance and delivering an understanding of persons' own laboratory test results; understandable terminology; easy to use; appropriate graphic design, and trustworthy information. CONCLUSIONS NLMP' evaluation confirmed the low utility of currently available laboratory medicine apps. A reliable app should contain trustworthy and understandable information. The appearance of an app should be fit for purpose and easy to use.

Abstract
Background Many of the mobile applications (apps) used for delivering health interventions involve laboratory medicine data. This survey was conducted to search the online market for health apps that manage laboratory medicine data. The aim was to review them and perform a quality evaluation. Methods Apps search criteria were "Lab results blood work", "Lab results", and "Health apps". After the stepwise exclusion process, 52 selected apps were downloaded and analyzed. For review and content analysis of the apps, a multidimensional tool for classifying and rating the quality of mobile health apps - Mobile App Rating Scale (MARS), was used. Results Selected apps were classified into five categories according to their intended use by patients or physicians, and the type of data engaged. Spearman's correlation analysis found significant correlations between MARS individual scoring items, as with the subjective quality and number of technical aspects. Kruskal-Wallis analysis showed a significant difference in the number of technical aspects employed, MARS engagement and informational quality score items, total score, and subjective quality. The lowest values for all of these items were in the category of apps designed for patients, and the post hoc test showed that the difference was statistically significant between this and the values in all other categories. Conclusions Apps designed for patients, are of the poorest quality, considering the total quality of the content and information they provide, estimated using the MARS tool. This estimation needs to be validated for laboratory medicine apps, and eventually modified after consideration of specific quality benchmarks.

Abstract
Background Nowadays over-the-counter (OTC) drugs and dietary supplements are widely used. Their use can have a significant impact on the validity of laboratory results. The aim of this multicenter European study was to determine the frequency of consumption of various dietary products and OTC drugs among patients and explore their level of knowledge and awareness about the potential impact of various products on laboratory test results. Methods Eighteen European countries participated in this study. The survey was carried out anonymously on a subsequent series of outpatients (n=200) in each participating country. Included were patients who were referred to the laboratory for blood sampling and who voluntarily agreed to participate in the study. The survey included questions about the frequency of consumption of various products, awareness of the importance of informing physicians and laboratory staff about it and information about influence of preanalytical factors in general on laboratory test results. Results In total, 68% of patients were regularly taking at least one OTC drug or dietary supplement. The frequency of patients consuming at least one OTC drug or dietary supplement differed between countries (p=0.001). Vitamins (38%), minerals (34%), cranberry juice (20%), acetylsalicylic acid (ASA) (17%) and omega fatty acids (17%) were the most commonly used in our study. Conclusions The use of various OTC drugs and dietary supplements is highly prevalent in Europe and patients are often not willing to disclose this information to the laboratory staff and ordering physician. The education of both patients and healthcare staff is needed.

Abstract
BACKGROUND There is increasing interest in direct patient engagement including receiving their laboratory medicine results. We previously established an appetite for Specialists in Laboratory Medicine to support patients in understanding results. The aim of this study was to establish whether patients agreed with such an approach, determined through surveying views in eight European countries. METHODS A standardized five-question survey was administered across eight European countries to a total of 1084 individuals attending medical outpatient clinics, with 100 patients each in Poland, Serbia, Netherlands, Turkey and Czech Republic, 101 in Estonia, 116 in Denmark and 367 in Norway. The responses across countries were compared using the chi-square test (p<0.05). RESULTS Patients wanting their results ranged from 50% to 94% (mean 65%) of those responding positively, a mean of 72% wanted additional information with their results; direct receipt was preferred over referral to a website. Specialists in Laboratory Medicine providing such information were acceptable to a mean of 62% of those respondents wishing their results; in countries where payment was possible, there was little interest in making additional payment for such a service. CONCLUSIONS A clear proportion of patients are interested in receiving their laboratory medicine results, the majority with explanatory notes; a role for Specialists in Laboratory Medicine is acceptable and raises the potential for direct engagement by such specialists with patients offering a new paradigm for the provision of laboratory medicine activities.

Abstract
BACKGROUND Low 25-hydroxyvitamin D (25[OH]D) and asthma development may be related to airway remodeling and eosinophilia. Periostin is proposed as a key molecule that links remodeling and eosinophilic inflammation. OBJECTIVE We evaluated the association of 25(OH)D concentration with periostin, peripheral blood eosinophil counts, and immunoglobulin E (IgE) in children with newly diagnosed asthma. METHODS The study included 150 children: 110 with atopic asthma and 40 constituted a reference group. Fasting blood was collected for cell counts and serum for measurements of 25(OH)D, periostin, IgE, and C-reactive protein (CRP) concentrations. RESULTS Significantly lower 25(OH)D, elevated IgE concentrations, and eosinophil counts were found in children with asthma compared with the reference group (p = 0.0001). A lower forced expiratory volume in the first second of expiration percentage predicted value was associated with a lower 25(OH)D value in children with asthma. The bronchodilator reversibility was inversely related to serum 25(OH)D concentrations (R = -0.45, p = 0.029). The children with asthma and with a 25(OH)D deficient concentration (≤20 ng/mL) had higher concentrations of periostin (p = 0.035) and CRP (p = 0.01) than those with a sufficient 25(OH)D concentration (≥30 ng/L). Additional analysis revealed statistically significant differences (p = 0.013) when comparing periostin concentrations between subjects with a 25(OH)D deficient concentration (≤20 ng/mL) and subjects who did not have a deficient concentration (>20 ng/mL). In individuals with asthma, a 25(OH)D concentration of <30 ng/mL had no impact on eosinophilia, whereas IgE concentrations were associated with increased eosinophils, and the effect of periostin on eosinophilia was small although significant. Multivariate regression, including 25(OH)D concentration, CRP level, eosinophil counts, and sex, accounted for 7% of periostin variation in subjects with asthma. CONCLUSION In newly diagnosed pediatric asthma, 25(OH)D concentrations revealed a small although significant association with periostin levels but no effect on eosinophilia. A low vitamin D concentration may increase airway remodeling induced by inflammatory mediators, but further clinical studies aimed to explain the causal link between vitamin D insufficiency and asthma are needed.

AbstractMedicine is a highly professionalized endeavour, by tradition centred on the authority of physicians. Better education and the advent of the information age cater for increased demands on society in general and on health care in particular to enable people to make informed decisions regarding themselves. Participation in medical decisions requires informed knowledge which is hard to obtain without substantial and time consuming professional help.We performed a survey amongst the member organizations of European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) in order to investigate the recognition and preparedness of providing help to patients in interpreting their laboratory results.Out of 40 EFLM Member Societies, 27 sent their responses to the survey. In most cases the first line delivery of laboratory results to physicians is by computer link (63%). Patients receive their laboratory results on demand from their physician in 60% of cases. However, 34% of laboratory specialists showed a negative attitude for delivering laboratory results to patients. Yet, in 48% of countries 1–5 patients per day ask a laboratory specialist about the significance of laboratory results outside the reference range. When patients are informed about the purpose of laboratory testing, they seek information primarily from their physician, followed by the internet and the Specialist in Laboratory Medicine.Changing practices increasingly enabling patient access to their records are on the increase facilitated by recent innovations in information technologies. Successful transfer of some of the responsibilities of physicians, demands a mutual triangular dialogue between the patient, their physician and laboratory medicine.

Abstract
Phosphorescence spectra at 103 K and delayed fluorescence and phosphorescence spectra at 296 K of flavomononucleotide (FMN) stabilized by poly(vinyl alcohol) PVA matrix have been measured. At 103 K the FMN monomer and excimer exhibit phosphorescence bands at about 620 and 640 nm, respectively. At 295 K the delayed fluorescence and phosphorescence of the FMN excimer exist together, revealing that FMN in the excited triplet state is an energetically well-isolated molecular complex which may play an important role in photobiological reactions.
