RESUMO
INTRODUCTION: Fourier-transform infrared imaging (FTIRI) enables examination of protein secondary structure in the analyzed tissues. The aim of our study was to examine the distribution of secondary structures in epiretinal membranes (ERMs) and internal limiting membranes (ILMs), and to explore possible associations to other diagnostic variables. METHODS: This prospective pilot study included patients scheduled for pars plana vitrectomy with membrane peeling. ERMs and ILMs were harvested during surgery and placed on a BaF2 window for postsurgical FTIRI analysis. Infrared hyperspectral images were subjected to second and fourth derivative analysis to obtain information of the protein secondary structures present in the tissues. RESULTS: Samples of 43 patients were analyzed, with the triple helical domain showing the highest prevalence in the examined tissues. The other secondary structures (beta-sheet, random coil, and beta-turn) showed a heterogenous distribution in the examined samples, without specific associations to indication of surgery, comorbidities, outcomes from optical coherence tomography, and intrasurgical findings. CONCLUSIONS: FTIRI enables analysis of the spatial distribution of protein secondary structures in the examined tissues; thus, it is a useful analytical technique for the analysis of ERMs and ILMs.

Osteocytes are terminally differentiated osteoblasts embedded within the bone matrix and key orchestrators of bone metabolism. However, they are generally not characterized by conventional bone histomorphometry because of their location and the limited resolution of light microscopy. OI is characterized by disturbed bone homeostasis, matrix abnormalities and elevated bone matrix mineralization density. To gain further insights into osteocyte characteristics and bone metabolism in OI, we evaluated 2D osteocyte lacunae sections (OLS) based on quantitative backscattered electron imaging in transiliac bone biopsy samples from children with OI type I (n = 19) and age-matched controls (n = 24). The OLS characteristics were related to previously obtained, re-visited histomorphometric parameters. Moreover, we present pediatric bone mineralization density distribution reference data in OI type I (n = 19) and controls (n = 50) obtained with a field emission scanning electron microscope. Compared to controls, OI has highly increased OLS density in cortical and trabecular bone (+50.66%, +61.73%; both p < 0.001), whereas OLS area is slightly decreased in trabecular bone (-10.28%; p = 0.015). Correlation analyses show a low to moderate, positive association of OLS density with surface-based bone formation parameters and negative association with indices of osteoblast function. In conclusion, hyperosteocytosis of the hypermineralized OI bone matrix associates with abnormal bone cell metabolism and might further impact the mechanical competence of the bone tissue.

OBJECTIVE: Early dental monitoring contributes substantially to good oral health in children. However, little is known on whether children from different geographical regions and gender are equally reached with current preventive and curative oral health strategies. The aim of our study therefore was to explore regional and gender differences in a population-based oral health dataset of Austrian children up to the age of 14. MATERIALS AND METHODS: We extracted the first electronically available health insurance data of children aged up to 14 years on dental services within a 4-year observation period in Austria and performed a separate analysis in up to 6-year-old children. In addition, we used a smaller randomly selected sample dataset of 3000 children as the large numbers would result in significant, but very small effects. RESULTS: In a total of 130,895 children, of whom 77,173 children (59%) were up to the age of six, we detected an east-west gradient: The eastern regions of Austria showed an older age at first contact and a higher number of dental services. A child aged up to 6 years who needed more than four dental services had a likelihood of 40% to be from Vienna, Austria's capital city located in the east. The smaller random sample did not show significant gender differences. CONCLUSIONS: Even in regions with a high density of dentists, such as Vienna, we obviously did not reach young children in the same extent as in other regions. CLINICAL RELEVANCE: Stratified interventions could be developed to overcome regional inequalities.

We examined differences in patients' survival after hip fracture (HF) and risk for subsequent HF among patients treated with oral and intravenous bisphosphonates (oBPs, iBPs), denosumab (DMAB), and patients without therapy. We used data from all patients in Austria aged ≥ 50 who sustained a HF between 2012 and 2017 and were followed for a subsequent HF and all-cause mortality until 2017. Antiosteoporotic treatment-naïve patients, who were incident users of BPs and DMAB, were eligible for propensity score matching 1:1 to obtain comparable user groups. We applied competing risk approach and calculated cumulative incidence functions and subdistribution-hazards for refracture. Cox regression models were applied for mortality risk. A total of 54,145 hip-fractured patients were observed (1919 oBPs; 1870 iBPs; 555 DMAB users; and 42,795 untreated patients were included in the matched sets) and followed up for a median (interquartile range) of 22.6 months (26.2). Patients treated with antiresorptive medications had significantly longer survival time than patients without treatment. Receiving treatment significantly decreased a hazard of dying only for women by 17% for iBPs (HR 0.83, 95% CI 0.71-0.98, p = 0.023). For DMAB and oBPs, the results were not statistically significant. Higher risk of a subsequent HF was observed in women on DMAB (SHR 1.77, 95% CI 1.08-2.91) and on iBP (SHR 1.81, 95% CI 1.35-2.41), and in men on oBPs (SHR 2.89, 95% CI 1.58-5.30). Patients who were treated with antiresorptive medications after HF had longer survival than patients without treatment, highlighting the importance of initiation of antiresorptive treatment after HF.

Background: Little is known about factors associated with mental health problems (MHP) of the elderly in socioeconomically deprived neighbourhoods, and comparisons between Central European and Western European countries on this topic are lacking. We examined whether MHP occurred more frequently in deprived neighbourhoods and among deprived people. Next, we examined whether the association of MHP with area deprivation differed by country and whether this could be explained by the socioeconomic (SE) characteristics of the residents. We obtained data on non-institutionalized residents aged 65 years and above from the EU-FP7: EURO-URHIS 2 project from Slovak ( N = 665, response rate 44.0%) and Dutch cities ( N = 795, response rate 50.2%). An elevated score on General Health Questionnaire-12 (≥2) indicated MHP. Education and household income with financial strain were used as measures of individual SE status. We employed multilevel logistic regression. Overall rates of MHP were significantly higher in Slovakia (40.6%) than in the Netherlands (30.6%). The neighbourhood unemployment rate was not associated with the mental health of elderly in either country. Rates of MHP were significantly higher among elderly with low and medium income [odds ratio (OR) = 1.75, 95% confidence interval (CI) = 1.16-2.62; OR = 1.64, 95% CI = 1.12-2.41, respectively] and financial strain (OR = 2.26, 95% CI = 1.56-3.28) when compared with those with high income and no strain, respectively. Individual-level SE characteristics explained differences between the two countries. The risk of MHP among the elderly is associated with their individual-level SE position but not with neighbourhood deprivation in both Slovakia and the Netherlands.

Background: Evidence shows that living in disadvantaged areas is associated with poor health. This may be due to the socioeconomic (SE) characteristics of both these residents and the areas where they live. Evidence regarding this on Central European (CE) countries is scarce. Our aim was to assess whether the prevalence of poor self-rated health (SRH) was higher in deprived urban areas, whether this can be explained by individual SE status (SES) and whether this differed between Slovakia and the Netherlands per age group. We examined the association of urban-level data and individual-level SE factors from different urban areas in different countries (Slovakia, the Netherlands) using comparable urban health indicators and area indicators. We also obtained unique data from the EU-FP7 EURO-URHIS 2 project. Multilevel logistic regression showed that poor SRH was associated with area deprivation in both countries. Regarding age by country, poor SRH occurred more frequently in the more deprived areas for the younger age group (≤64) in the Netherlands but for the older age group (≥65 years) in Slovakia. Moreover, Slovak citizens reported poor SRH significantly more often than Dutch residents. Individual SES was significantly associated with poor SRH in both age groups and both countries for most area-level SE measures. Individual SES is associated with SRH more strongly than area deprivation. Therefore, it is important to account for relative deprivation at an individual level when considering health-enhancing activities. Moreover, the effect of urban-area deprivation seems to differ between CE and WE countries.

BACKGROUND: Health-risk behaviours (HRB) increase the risk of disability and chronic diseases at an older age. This study aimed to compare Slovakia and the Netherlands regarding differences in the prevalence of HRB by neighbourhood and individual deprivation and to determine whether area differences could be explained by the socio-economic position (SEP) of the residents. METHODS: We obtained data on non-institutionalized residents aged ≥ 65 years from the EU-FP7: EURO-URHIS 2 project from Slovak (N = 665, response rate 44.0%) and Dutch cities (N = 795, response rate 50.2%). HRB concerned daily smoking, binge drinking, physical activity, consumption of fruits and vegetables and body mass index. Area deprivation was measured by the neighbourhood unemployment rate. Individual SEP was measured by education and household income with financial strain. We used multilevel logistic regression. RESULTS: In Slovakia, no HRB was associated with either neighbourhood unemployment or individual SEP. The elderly in the Netherlands from the least favourable neighbourhoods were more likely to be daily smokers [odds ratio (OR) 2.32; 95% confidence interval (CI) 1.25, 4.30] and overweight (OR 1.84; 95% CI 1.24, 2.75) than residents from the most favourable ones. For the Dutch elderly the gradients varied per HRB and per individual-level SEP indicator. Individual SEP explained country differences in the association of area unemployment with smoking and lack of physical activity but not that with overweight. CONCLUSION: Countries differed in the associations with HRB of both neighbourhood unemployment and individual SEP among the elderly urban residents. The local importance of socio-economic factors on both levels should be considered when developing health-promotion activities for the elderly.

BACKGROUND: A balanced diet rich in calcium and protein is recommended for bone-healthy people and osteoporosis patients, but it may also be important for rare bone disease (RBD). Little data is available on RBD and diet. Therefore, the aim of this study was to evaluate the nutritional behavior of patients with RBD. METHODS: This single-center, cross-sectional, questionnaire-based study assessed the nutritional behavior of RBD patients (X-linked hypophosphatemia (XLH), osteogenesis imperfecta (OI), hypophosphatasia (HPP)), osteoporosis (OPO) patients and healthy controls (CTRL). The nutritional questionnaire comprised 25 questions from seven nutritional areas. The associations between socioeconomic factors and BMI were assessed by age-adjusted univariate analysis of covariance (ANCOVA). RESULTS: Fifty patients with RBD (17 OI, 17 HPP, 16 XLH; mean age of 48.8 ± 15.9, 26.0% male, mean BMI 26.2 ± 5.6), 51 with OPO (mean age 66.6 ± 10.0, 9.8% male, mean BMI 24.2 ± 3.9) and 52 CTRL (mean age 50.8 ± 16.3, 26.9% male, mean BMI 26.4 ± 4.7) participated. Twenty-six (52.0%) RBD, 17 (33.4%) OPO and 24 (46.1%) CTRL were overweight or obese according to BMI. Only a minority of RBD, OPO and CTRL had a daily intake of at least three portions of milk or milk products (17.3% RBD, 15.6% OPO, 11.6% CTRL, p = 0.453). In general, similar nutritional behavior was observed between the three subgroups. However, significant differences were found in caffeine consumption (p = 0.016), fruit/vegetable juice consumption (p = 0.034), portions of fish per week (p = 0.044), high-fat meals per week (p = 0.015) and consumption of salty snacks (p = 0.001). CONCLUSION: Nutritional counseling, controlling BMI and ensuring sufficient calcium and protein intake are crucial in patients with osteoporosis as well as in rare bone diseases. Vitamin D does not appear to be sufficiently supplied by the diet, and therefore supplementation should be considered in patients with bone diseases.

Osteoporosis is a widespread disease and affects over 500,000 people in Austria. Fragility fractures are associated with it and represent not only an individual problem for the patients, but also an enormous burden for the healthcare system. While trauma surgery care is well provided in Vienna, there is an enormous treatment gap in secondary prevention after osteoporotic fracture. Systematic approaches such as the Fracture Liaison Service (FLS) aim to identify patients with osteoporosis after fracture, to clarify diagnostically, to initiate specific therapy, and to check therapy adherence. The aim of this article is to describe the practical implementation and operational flow of an already established FLS in Vienna. This includes the identification of potential FLS inpatients, the diagnostic workup, and recommendations for an IT solution for baseline assessment and follow-up of FLS patients. We summarize the concept, benefits, and limitations of FLS and provide prospective as well as clinical and economic considerations for a city-wide FLS, managed from a central location. Future concepts of FLS should include artificial intelligence for vertebral fracture detection and simple IT tools for the implementation of FLS in the outpatient sector.

OBJECTIVES: To assess physical and mental health domains of health related quality of life (HRQoL) as well as fatigue in rare bone disease (RBD) patients and to compare to patients with osteoporosis (OPO) and healthy controls (CTRL) without known bone diseases and to study associations of Fatique Severity Scale (FSS) with eight domains of HRQoL. METHODS: Monocentric, cross-sectional study carried out between 2020 and 2022 in a hospital affiliated with the Vienna Bone and Growth Center (European Reference Network Center for Rare Bone Disease) in Vienna, Austria. The study comprised three types of RBD: Osteogenesis imperfecta, Hypophosphatasia and X-linked Hypophosphatemia. Fatigue was assessed by FSS. The higher score indicates more fatigue severity. HRQoL was assessed by Short-Form Health Survey (SF-36 v2). Physical component (PCS) and mental component summary scores (MCS) were calculated and normalised to a general population. A higher score indicates better HRQoL. Age-adjusted ANCOVA was used to assess differences in PCS and MCS between groups. Spearman correlation was used for associations of FSS with eight domains of HRQoL. RESULTS: Study comprised 50 RBD patients [Mean age (SD) 48.8 (±15.9), 26 % male], 51 OPO patients [66.6 (±10.0), 9.8 % male] and 52 controls [50.8 (±16.3), 26.9 % male]. RBD patients had significantly higher mean age-adjusted FSS (3.5, 95 % CI 3.1-4.0) than controls (2.6, 95 % CI 2.2-3.0, p = 0.008), but not in comparison to osteoporotic patients 2.6 (95 % CI 2.2-3.0, p = 0.69). Diminished age-adjusted PCS of HRQoL was observed in RBD patients with a mean score of 37.1 (95 % CI 33.4-40.8), whereas their MCS of 50.1 (95 % CI 46.6-53.7) was comparable to controls (52.9, 95 % CI 49.8-56.0) and osteoporotic patients (50.2, 95 % CI 45.4-54.9). FSS score was negatively correlated with physical and mental component in RBD (ρ = -0.37, p < 0.05 and ρ = -0.54, p < 0.01, respectively) and OPO patients (ρ = -0.37, p < 0.05 and ρ = -0.35, p < 0.01, respectively). CONCLUSIONS: The HRQoL in adult patients with rare bone diseases is lower than compared to osteoporotic and control group in this Austrian population. Fatigue has significant negative impact on HRQoL and it is important to address it when meeting with RBD patients in clinical practice.

(1) Background: The use of complementary and alternative medicine (CAM) has seen a notable increase in popularity. However, there is an absence of data regarding the prevalence of CAM use in patients with rare bone diseases (RBDs). (2) Methods: This monocentric, cross-sectional study was carried out in a reference hospital for RBDs. RBD patients included individuals with osteogenesis imperfecta, hypophosphatasia and X-linked hypophosphatemia, and their data were compared with those of patients with osteoporosis (OPO) and of healthy controls (CON). This study utilized the German version (I-CAM-G) of the I-CAM questionnaire. (3) Results: This study comprised 50 RBD patients [mean age (SD) of 48.8 (±15.9), 26% male], 51 OPO patients [66.6 (±10.0), 9.8% male] and 52 controls [50.8 (±16.3), 26.9% male]. Treatments by naturopaths/healers were more prevalent in the RBD group (11.4%) compared with OPO (0%) and CON (5.8%) (p = 0.06). More than half of the OPO (60.8%) and CON (63.5%) patients and 46% of the RBD patients reported vitamin/mineral intake within the past 12 months (p = 0.16). Individuals with tertiary education had a significantly higher odds ratio of 2.64 (95% CI: 1.04-6.70, p = 0.04) for visiting any CAM provider. Further, OPO patients were significantly less likely to use self-help techniques compared with the CON group (OR = 0.42, 95% CI: 0.19-0.95; p = 0.04). (4) Conclusions: Herbal medicine, vitamin and mineral supplements, and self-help techniques were the most common forms of CAM reported by patients with RBDs. However, the use of CAM was generally low.

It is not well established to what extent previous immunizations offer protection against infections with the SARS-CoV-2 Omicron variant in dialysis patients. We aimed to define the relevant humoral response in dialysis patients using a SARS-CoV-2 IgG chemiluminescence microparticle immunoassay (CMIA) compared to the activity of neutralizing antibodies assessed by a virus neutralization test. Next, we aimed to determine differences in humoral and cellular response levels over time among patients infected or not infected by the Omicron variant of SARS-CoV-2. Immunological parameters of cellular and humoral response to SARS-CoV-2 were analyzed at baseline and after 3 (T3), 6 (T6) and 14 months (T14). In this monocentric cohort study, we followed 110 dialysis patients (mean age 68.4 ± 13.7 years, 60.9% male) for a median of 545 days. We determined an anti-SARS-CoV-2 IgG level of 56.7 BAU/mL as an ideal cut-off value with a J-index of 90.7. Patients infected during the Omicron era had significantly lower (p < 0.001) mean antibody levels at T0 (3.5 vs. 111.2 BAU/mL), T3 (269.8 vs. 699.8 BAU/mL) and T6 (260.2 vs. 513.9 BAU/mL) than patients without Omicron infection. Patients who developed higher antibody levels at the time of the basic immunizations were less likely to become infected with SARS-CoV-2 during the Omicron era. There is a need to adjust the cut-off values for anti-SARS-CoV-2 IgG levels in dialysis patients.
RESUMO
(1) Background: Pelvic fractures (PFs) are related to osteoporosis, and represent a serious individual and socioeconomic burden. (2) Methods: We examined age- and sex-standardised incidence rates (SIRs) of PF, along with rates of all-cause overall and one-year mortality among patients with PF. We compared the mortality rates between PF patients and a matched fracture-free cohort. Patients ≥50 years old in Austria hospitalised with PF in 2010−2018, along with their dates of death, were recorded. (3) Results: We identified 54,975 patients with PF, of whom 70.9% were women. Between 2010 and 2018 the SIR of PF increased in men by 10.0%from 125.3 (95% Confidence Interval 118.9−132.0) to 137.8 (95% CI 131.8−144.0) per 100,000and in women by 2.7%from 218.7 (95% CI 212.0−225.6) to 224.7 (95% CI 218.3−231.3) per 100,000. The one-year post-PF mortality rate was higher in men than in women (13.0% and 11.1%, respectively; p < 0.001). Pelvic fracture patients aged ≥65 had an elevated mortality risk (Hazard Ratio 1.75, 95% CI 1.71−1.79, p < 0.001) compared to controls. (4) Conclusions: There is a clear increase in the incidence of PF in the elderly population, with a greater increase in men over time. Pelvic fracture itself contributes to increased mortality in individuals aged 65 and above.
RESUMO
OBJECTIVES: Caring for osteoporosis patients has proven challenging during the COVID-19 pandemic due to repeated lockdowns in Austria. The distinct possibility of insufficient treatment regimens is therefore a matter of pressing concern. The aim of the study was to assess alterations in dispensing anti-osteoporotic drugs during the COVID-19 pandemic. PATIENTS/METHODS: This study was a nationwide retrospective register-based observational study which included all patients in Austria aged ≥50 who received at least one prescription for anti-osteoporotic medication between January 2016 and November 2020. Pseudonymised individual-level patients' data were obtained from social insurance authorities. Anti-osteoporotic agents were divided into: (i) oral bisphosphonates, (ii) intravenous bisphosphonates, (iii) selective estrogen receptor modulators (SERMs), (iv) teriparatide (TPTD) and (v) denosumab (DMAB). We used interrupted time series analysis with autoregressive integrated moving average models (ARIMA) to predict drug dispensing. RESULTS: There were 2,884,374 dispensations of anti-osteoporotic drugs to 224,598 patients between 2016 and 2020. The mean monthly prescriptions for oral bisphosphonates (-14.5 %) and SERMs (-12.9 %) decreased during the COVID-19 pandemic when compared to the non-COVID-19 period. Dispensing for intravenous bisphosphonates (1.7 %) and teriparatide (9.5 %) increased. Prescriptions for DMAB decreased during the first lock-down, however increased by 29.1 % for the total observation time. The Arima models showed that in March 2020 (beginning of the 1st COVID-19 lockdown), there was a decrease of 778 dispensings, with a further increase of 14 dispensings every month for denosumab; a decrease by 178 dispensings, with a further increase of 23 dispensings every month for zolendronic acid; a decrease by 2950 dispensings, but with a further increase of 236 dispensings every other month for ibandronate and a decrease by 1443 dispensing with a further decrease of 29 dispensings for alendronate than predicted, had the lockdown not occurred. CONCLUSIONS: The total number of prescriptions dispensed to patients treated with anti-osteoporotic medications declined rapidly during first COVID-19 lockdown. The observed decrease of DMAB during the first lockdown rebounded in the following months. Considering the massive treatment gap for osteoporosis, and the related fracture risk, clinicians should continue treatment, even during a pandemic.

BACKGROUND: The most frequent manifestation in adult hypophosphatasia (HPP) is musculoskeletal pain. The unspecific nature of its clinical presentation may prevent correct diagnosis. The aim of the study was to assess the prevalence of ALPL mutations in adult patients treated in rheumatological outpatient facilities with evident musculoskeletal symptoms typical for HPP. METHODS: Over a period of 10 years 9,522 patients were screened in the rheumatology outpatient clinic of the Hanusch hospital Vienna. Serum ALP levels ≤ 40 U/L were found in 524 patients. After screening for secondary causes, 73 patients were invited for clinical evaluation. Genetic testing was performed in 23 patients with suspected HPP. Logistic regression models with Firth penalisation were used to estimate the unadjusted and BMI-adjusted association of each clinical factor with HPP. RESULTS: Mutations in the ALPL gene were observed in 57% of genetically screened patients. Arthralgia, fractures, and pain were the leading symptoms in individuals with ALPL mutation. Chondrocalcinosis (OR 29.12; 95% CI 2.02-1593.52) and dental disease (OR 8.33; 95% CI 0.93-143.40) were associated with ALPL mutation, independent of BMI. Onset of symptoms in patients with ALPL mutation was at 35.1 (14.3) years, with a mean duration from symptoms to diagnosis of 14.4 (8.1) years. Bone mineral density (BMD) and trabecular bone score (TBS) as well as bone turnover markers were not indicative for HPP or ALPL mutation. CONCLUSION: HPP can mimic rheumatologic diseases. Thus, HPP should be considered as a possible diagnosis in adult patients presenting with musculoskeletal pain of unknown origin in rheumatology outpatient clinics. In patients with persistently low ALP serum levels and unclear musculoskeletal pain, HPP as the underlying cause has to be considered.

OBJECTIVE: Patients with diabetes have an increased risk of osteoporosis and shorter life expectancy. Hip fracture (HF) is the most serious consequence of osteoporosis and is associated with increased mortality risk. We aimed to assess the association of antidiabetic medications with HF and the post-hip fracture mortality risk among diabetic patients ≥50 years. DESIGN: In this nationwide case-control study 53 992 HF cases and 112 144 age-, sex- and region-matched non-hip fracture controls were analyzed. A cohort of hip-fractured diabetic patients were followed-up for an all-cause mortality. METHODS: We defined three groups of diabetic patients based on a prescription of antidiabetic medications: group 1 treated with insulin monotherapy (G1DM), group 2 (G2DM) treated with blood glucose-lowering drugs (BGLD) only, group 3 on a combined BGLD and insulin therapy (G3DM). We applied logistic regression and Cox regression. RESULTS: We identified 2757 G1DM patients, 15 310 G2DM patients, 3775 G3DM patients and 144 294 patients without any antidiabetic treatment. All three groups of diabetic patients had increased odds of HF compared to controls. G1DM patients aged 50-64 years (aOR: 4.80, 95% CI: 3.22-7.17) and G3DM patients (aOR: 1.39, 95% CI: 1.02-1.88) showed the highest HF odds, whereas G2DM patients had 18% decrease in HF odds than their non-diabetic controls (aOR: 0.82, 95% CI: 0.69-0.99). All diabetic patients had increased post-hip fracture mortality risk compared to non-diabetic controls. The highest mortality hazard was observed in G1DM patients, being greater for women than men (HR: 1.71, 95% CI: 1.55-1.89 and HR: 1.44, 95% CI: 1.27-1.64, respectively). CONCLUSIONS: Antidiabetic medications increase the probability of HF. Diabetic patients, who sustained HF have a higher mortality risk than non-diabetic patients.

BACKGROUND: Osteogenesis imperfecta (OI) is a rare genetic disorder characterized by impaired bone quality and quantity. Established imaging techniques have limited reliability in OI. The TX-Analyzer™ is a new, fractal-based software allowing a non-invasive assessment of bone structure based on conventional radiographs. We explored whether the TX-Analyzer™ can discriminate OI patients and healthy controls. Furthermore, we investigated the correlation between TX-Analyzer™ parameters and (i) bone mineral density (BMD) by Dual Energy X-ray Absorptiometry (DXA), (ii) trabecular bone score (TBS), and (iii) bone microstructure by high-resolution peripheral quantitative computed tomography (HR-pQCT). MATERIAL AND METHODS: Data of 29 adult OI patients were retrospectively analyzed. Standard radiographs of the thoracic and lumbar spine were evaluated using the TX-Analyzer™. Bone Structure Value (BSV), Bone Variance Value (BVV), and Bone Entropy Value (BEV) were measured at the vertebral bodies T7 to L5. Data were compared to a healthy, age- and gender-matched control group (n = 58). BMD by DXA, TBS, and trabecular bone microstructure by means of HR-pQCT were correlated to TX-Analyzer™ parameters in OI patients. The accuracy of the TX-Analyzer™ parameters in detecting OI was assessed with area under curve (AUC) analysis of receiver operating characteristic (ROC). RESULTS: BEV of the thoracic and the lumbar spine were significantly lower in OI patients compared to controls (both p < 0.001). BEV of the thoracic spine was significantly correlated to TBS (ρ = 0.427, p = 0.042) as well as trabecular number (Tb.N) at the radius (ρ = 0.603, p = 0.029) and inhomogeneity of the trabecular network (Tb.1/N.SD) at the radius (ρ = -0.610, p = 0.027), when assessed by HR-pQCT. No correlations were found between BEV and BMD by DXA. BEV of the thoracic and the lumbar spine had an AUC of 0.81 (95% confidence interval [CI] 0.67-0.94, p < 0.001) and 0.73 (95% CI 0.56-0.89, p = 0.008), respectively. BSV and BVV did not differ between OI patients and controls. CONCLUSION: The software TX-Analyzer™ is able to discriminate patients with OI from healthy controls. ROC curves of BEV values suggest a suitable clinical applicability. Low to no correlations with conventional methods suggest, that the TX-Analyzer™ may indicate a new and independent examination tool in OI.

BACKGROUND AND AIMS: With rising rates of inflammatory bowel diseases [IBD] in older adults, management of comorbidities such as osteoporosis is becoming increasingly important. Hip fracture [HF] is the most serious consequence of low bone mineral quality and is associated with excess risk of mortality. For older IBD patients, there are only limited data available. Therefore, we aimed to assess the association of IBD with HF, and all-cause mortality risk after HF, among IBD patients older than 50 years. METHODS: In a national database-registered case-control study, 56 821 HF cases aged ≥50 years, and 113 718 age-, sex- and region-matched non-hip-fracture controls, were analysed between 2012 and 2016. A history of IBD was assessed from data from Austrian social health insurance funds. Logistic regression and Cox proportional multivariate models were used to test the association of IBD with HF and post-hip fracture mortality risk. RESULTS: A total of 531 patients were identified with IBD (25.0% men, mean age 81.2 years, standard deviation [SD] 9.7). Analysis, adjusted for anti-osteoporotic treatment, use of glucocorticoids, and selected medications, showed that IBD patients had an increased odds of HF (odds ratio [[OR] 2.22, 95% confidence interval [CI] 1.86-2.64). Patients with Crohn's disease [CD] revealed a higher HF odds in contrast to patients with ulcerative colitis [OR 2.91, 95% CI 2.17-3.89 and OR 1.89, 95% CI 1.52-2.35, respectively]. Overall mortality risk after HF was higher among female CD patients [HR 1.75, 95% CI 1.28-2.41] than in the general population. CONCLUSIONS: IBD was strongly associated with HF in older patients. Post-hip fracture mortality risk was elevated particularly in women with CD.

Crohn's disease (CD) is associated with bone loss and increased fracture risk. TX-Analyzer™ is a new fractal-based technique to evaluate bone microarchitecture based on conventional radiographs. The aim of the present study was to evaluate the TX-Analyzer™ of the thoracic and lumbar spine in CD patients and healthy controls (CO) and to correlate the parameters to standard imaging techniques. 39 CD patients and 39 age- and sex-matched CO were analyzed. Demographic parameters were comparable between CD and CO. Bone structure value (BSV), bone variance value (BVV) and bone entropy value (BEV) were measured at the vertebral bodies of T7 to L4 out of lateral radiographs. Bone mineral density (BMD) and trabecular bone score (TBS) by dual energy X-ray absorptiometry (DXA) were compared to TX parameters. BSV and BVV of the thoracic spine of CD were higher compared to controls, with no difference in BEV. Patients were further divided into subgroups according to the presence of a history of glucocorticoid treatment, disease duration > 15 years and bowel resection. BEV was significantly lower in CD patients with these prevalent risk factors, with no differences in BMD at all sites. Additionally, TBS was reduced in patients with a history of glucocorticoid treatment. Despite a not severely pronounced bone loss in this population, impaired bone quality in CD patients with well-known risk factors for systemic bone loss was assessed by TX-Analyzer™.
RESUMO
CONTEXT: There is little information on health situation of the people of rural Slovak Republic. The rural environment is often a mixture of natural and man-made hazards, which under some conditions, might turn to be a health risk to humans. PURPOSE: The aim of this study was to compare two regions of the Slovak Republic, two different hazards (natural and man-made), two different methods of health outcome measurement (routine statistics and individual diary based data). METHODS: Ecological study design with focus on cancer incidence analysis was employed in case of natural hazard analysis. Standardized incidence ratios (SIR) were calculated and are presented in paper. Observational study design was employed to study rural gardening practices and their impact on health. FINDINGS: Statistically significant differences in SIR were found in rural areas of Spis-Gemer Region (SGR) among males for lip, oral cavity and larynx (1.60, CI 95% 1.12-2.34), respiratory (1.25, CI 95% 1.01-1.55) and digestive organ cancers (1.22, CI 95% 1.01-1.47); hematopoetic cancers are significantly elevated among males in rural areas as well (1.58, CI 95% 1.05-2.39). Pesticide use (83.1% of gardeners use pesticides) without any protective equipment is still widespread among gardeners in rural Slovak Republic (16.9%). The produced fruits and vegetables are substantial part of total fruit and vegetable consumption (51% in summer and 42.7% in winter season) increasing the risk of exposure to pesticides. CONCLUSION: Our study shows that on ecological level, mortality and morbidity statistics could be used to assess human health status in linkage to broad exposure measures (urban-rural); on dose response level (arsenic in soil) this method lacks sensitivity. Health survey and diary method on the other hand are useful tools in analysis of rural health especially with respect to man-made hazards.
