Vitamin B12 supplementation and health behavior of Austrian vegans: a cross-sectional online survey.

The number of vegans is increasing and was estimated at 2.0% of the Austrian population. Austrian vegans were found to have lower intakes and levels of vitamin B12 compared to vegetarians and omnivores. Vegans are advised to consume reliable sources of vitamin B12, e.g., in the form of dietary supplements or fortified foods. This study aimed to investigate health and supplementation behavior, with special emphasis on the supplementation of vitamin B12, and to demographically characterize the community of Austrian adult vegans. A nonrandom, voluntary sample of adult vegans with a principal residence in Austria was recruited with an online cross-sectional survey via social media and messenger platforms. Associations between respondent characteristics (gender, education, nutritional advice by a dietitian or nutritionist) and health/supplementation behaviors were examined by cross-tabulation. The questionnaire was completed by 1565 vegans (completion rate 88%), of whom 86% were female, the median age was 29 years, 6% were obese, and 49% had completed an academic education. Ninety-two percent consumed vitamin B12 through supplements and/or fortified foods, and 76% had their vitamin B12 status checked. The prevalence of vitamin B12 intake through supplements and/or fortified foods was slightly (not statistically significant) higher among women vs. men (93% vs. 89%), those who were academically educated vs. those who were not (93% vs. 91%), and those who had taken nutritional advice vs. those who had not (97% vs. 92%). Professional nutritional advice had been taken by only 9.5% of female and 8.4% of male respondents. Those who had taken advice reported a lower smoking prevalence (p = 0.05, φ = 0.05), higher prevalence of checking vitamin B12 status (p < 0.01, φ = 0.10), vit B12 intake through supplements and/or fortified foods (p = 0.03, φ = 0.05), and taking supplements of omega-3 (p < 0.01, φ = 0.14), selenium (p = 0.02, φ = 0.06), and iodine (p = 0.02, φ = 0.06). Austrian vegans can be characterized as predominantly young, female, urban, highly educated, and nonobese. The rate of vitamin B12 intake through supplements and/or fortified foods is fairly high (92%), but should be further improved e.g., by increasing the share of vegans who follow professional nutritional advice (requiring a diploma in dietetics, nutritional science, or medicine in Austria).

Oral Contraceptive Intake and Iodine Status in Young Women.

OBJECTIVE: Similar to pregnant women, women taking an oral contraceptive (OC) might have elevated iodine requirements due to the altered hormonal state. This is the first study aimed at investigating the prevalence of iodine deficiency and possible influences of OC intake on urine creatinine and iodine levels in young women. METHODS: One hundred fifty-five women between the age of 18 and 35 years (62 taking an OC and 93 controls) participated in a cross-sectional pilot study at the Medical University of Vienna, which included a 1-spot urine sample and a questionnaire on OC intake as well as a food questionnaire. RESULTS: The median urinary iodine concentration (UIC) in this study was 68 µg/L (41, 111 µg/L) suggesting an inadequate iodine status in the women according to the WHO guidelines. Median UIC (OC: 89 µg/L, IQR 55-120; control: 59 µg/L, IQR 39-91, p = 0.010) and urine creatinine (OC: median = 99.0 µg/L, IQR 74.9-175.5; control: 77.0 µg/L, IQR 49.6-147.2, p = 0.030) levels were significantly higher in OC women than in the control group. UIC corrected for urine creatinine was comparable between both groups. CONCLUSION: With similar creatinine-corrected UICs in both groups, OC intake might not have a significant impact on iodine status. However, the low median UIC in a vulnerable group of young women potentially conceiving in the following years points at the necessity of optimizing the iodine intake in the Austrian population and reiterates the insufficiency of the current iodine supplementation measures.

Translating the Burden of Pollen Allergy Into Numbers Using Electronically Generated Symptom Data From the Patient's Hayfever Diary in Austria and Germany: 10-Year Observational Study.

BACKGROUND: Pollen allergies affect a significant proportion of the population globally. At present, Web-based tools such as pollen diaries and mobile apps allow for easy and fast documentation of allergic symptoms via the internet. OBJECTIVE: This study aimed to characterize the users of the Patient's Hayfever Diary (PHD), a Web-based platform and mobile app, to apply different symptom score calculations for comparison, and to evaluate the contribution of organs and medications to the total score for the first time. METHODS: The PHD users were filtered with regard to their location in Austria and Germany, significant positive correlation to the respective pollen type (birch/grass), and at least 15 entries in the respective season. Furthermore, 4 different symptom score calculation methods were applied to the datasets from 2009 until 2018, of which 2 were raw symptom scores and 2 were symptom load index (normalized) calculations. Pearson correlation coefficients were calculated pairwise for these 4 symptom score calculations. RESULTS: Users were mostly male and belonged to the age groups of 21 to 40 years or >40 years. User numbers have increased in the last 5 years, especially when mobile apps were made available. The Pearson correlation coefficients showed a significant linear relationship above 0.9 among the 4 symptom score datasets and thus indicated no significant difference between the different methods of symptom score calculation. The nose contributed the most to the symptom score and determined about 40% of the score. CONCLUSIONS: The exact method of calculation of the symptom score is not critical. All computation methods show the same behavior (increase/decrease during the season). Therefore, the symptom load index is a useful computation method in all fields exploring pollen allergy, and Web-based diaries are a globally applicable tool to monitor the effect of pollen on human health via electronically generated symptom data.

Thirty-five-year trend in the prevalence of refractive error in Austrian conscripts based on 1.5 million participants.

BACKGROUND: To quantify the current burden of myopia and hyperopia in Austrian young men and the time trend of myopia in the past 35 years by individual and social correlates. METHOD: We included data on all Austrian military conscripts from 1983 to 2017 (n=1 507 063) from six medical investigation stations. Young men provided data on education, weight and height for calculating body mass index, blood pressure and resting heart rate. Non-cycloplegic refractions were measured by an autorefractometer. Spherical equivalent was calculated by standard formula (sphere+cylinder/2, unit dioptres (D)). Myopic refractive error was defined as <-0.5 D). Hyperopic refractive error was defined as >0.5 D. RESULTS: The largest burden of refractive error in Austria is myopia, which rose from 13.8% to 24.4% over 35 years, with less than 5% hyperopic population. Over time, the prevalence of myopia was constantly lower yet increased more rapidly among those with low education levels (11.4%-21.7%) compared with those with higher education (24.5%-29.6%) in all medical investigation stations. We found consistent associations of some unfavourable health indicators (underweight: ORs 1.1-1.4, higher resting heart rate: all p trend <0.001) with higher myopia prevalence, which point towards lifestyle factors playing an important role in the development of myopia. CONCLUSION: Primary preventive measures are needed to curb the observed trend in myopia among Austrian young men. Future research should investigate the impact of modifiable factors on myopia development and progression, particularly lifestyle factors that are dramatically shifting.

Head and neck cancer in Styria : An epidemiologic and clinical audit.

BACKGROUND: The outcome of patients with cancer of the head and neck is significantly improved by increased interdisciplinary cooperation. The main focus of this study was a comparison of epidemiologic factors (age, sex, origin, staging) of patients with head and neck cancer in Styria, with those for patients throughout Austria. METHODS: A retrospective data analysis of collected archived tumor board protocols of the Comprehensive Cancer Center (CCC) Graz included the patient's age, sex, area of residence, TNM stage, reasons for inoperability, comorbidities and performance status by ECOG (Eastern Cooperative Oncology Group), was performed. This study focuses on 340 patients who presented with a head and neck malignancy for the first time. RESULTS: In the period from January 2014 to December 2015 a total of 252 men (74.1%) and 88 women (25.9%) with malignant head and neck tumors, were presented in the tumor board for the first time. The mean age at diagnosis was 63.4 years. In 45.5% the patients already demonstrated advanced tumor stages (T4 = 27.9%, T3 = 17.6%). Most newly diagnosed neoplasms were cancers of the oropharynx (24.1%), larynx (19.4%) and oral cavity (18.8%) and 36.5% were considered to be inoperable. Curative and palliative treatments were initiated in 83.2% and 16.9%, respectively. CONCLUSION: The region of south Styria showed a higher incidence of T3 and T4 tumors of the oropharynx than the average Austrian population. Measures to increase awareness of this problem should be initiated to support general otorhinolaryngologists and general practitioners in detecting oropharyngeal cancers at an earlier stage.

Cancer rehabilitation: current trends and practices within an Austrian University Hospital Center.

Background: Cancer rehabilitation has the goal to improve functional status, quality of life, participation, and can improve quality of patient-centered programs and health care efficiencies. In Austria, inpatient cancer rehabilitation is well established but outpatient rehabilitation has not yet established well.Methods: The present article is describing current rehabilitation in practice and focuses on cancer rehabilitation in Austria, namely bringing together a descriptive account of current trends and practices within an Austrian University Hospital Center (General Hospital of Vienna linked to the Medical University of Vienna) and the Comprehensive Cancer Centre (CCC) Vienna, Austria.Results: Cancer Rehabilitation in the described Austrian University Hospital Center is well developed due to the help of all different clinics dealing with cancer patients and of the opinion leaders of the CCC Vienna. The Department of Physical Medicine, Rehabilitation, and Occupational Medicine of the Medical University of Vienna as a part of the CCC Vienna with his "Pioneer-Status" and the described milestones has been integrated in the national cancer rehabilitation concept of our country from the beginning.Conclusions: Also in Austria, Physical Medicine and Rehabilitation with competencies in diagnostic and therapy as well as of coordination of the multiprofessional and interdisciplinary rehabilitation teams is an important part of cancer rehabilitation.Implications for rehabilitationCancer rehabilitation is an important part in the treatment and care of cancer patients with the goal to improve functional status, quality of life, and participationCancer rehabilitation helps cancer survivors to be integrated in their normal live, namely to increase social participation and/or workabilityThe field of Physical Medicine and Rehabilitation with competencies in diagnostic and therapy as well as of coordination of the multi-professional and interdisciplinary rehabilitation teams is an important part of cancer rehabilitationInterventions and treatment approaches from the field of Physical Medicine and rehabilitation include the application of Physical Modalities like electrotherapy, thermotherapy, balneology and climatic therapy, phototherapy, and mechanotherapy Cancer rehabilitation has to be early integrated into the cancer care continuum.

Prevalence and burden of headache in children and adolescents in Austria - a nationwide study in a representative sample of pupils aged 10-18 years.

BACKGROUND: Headache disorders are highly prevalent worldwide, but not so well investigated in children and adolescents as in adults: few studies have included representative nationwide samples. No data exist for Austria until now. In a representative sample of children and adolescents in Austria, we estimated the prevalence and attributable burden of headache disorders, including the new diagnostic category of "undifferentiated headache" (UdH) defined as mild headache lasting less than 1 hour. METHODS: Within the context of a broader national mental health survey, children and adolescents aged 10-18 years were recruited from purposively selected schools. Mediated self-completed questionnaires included sociodemographic enquiry (gender, age, socioeconomic status, family constellation, residence [urban or rural] and migration background). Prevalence and attributable burden of all headache, UdH, migraine (definite plus probable), tension-type headache (TTH: definite plus probable) and headache on ≥15 days/month (H15+) were assessed using the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire for children and adolescents. Health-related quality of life (HrQoL) was assessed using the KIDSCREEN questionnaire. RESULTS: Of 7643 selected pupils, 3386 (44.3%) completed the questionnaires. The 1-year prevalence of headache was 75.7%, increasing with age and higher in girls (82.1%) than in boys (67.7%; p < 0.001). UdH, migraine, TTH and H15+ were reported by 26.1%, 24.2%, 21.6% and 3.0% of participants. Attributable burden was high, with 42% of those with headache experiencing restrictions in daily activities. Medication use (50% overall) was highest in H15+ (67%) and still considerable in UdH (29%). HrQoL was reduced for all headache types except UdH. Participants in single parent or patchwork families had a higher probability of migraine (respectively, OR 1.5, p < 0.001; OR 1.5, p < 0.01). Participants with a migration background had a lower probability of TTH (OR 0.7, p < 0.01). CONCLUSIONS: Headache disorders are both very common and highly burdensome in children and adolescents in Austria. This study contributes to the global atlas of headache disorders in these age groups, and corroborates and adds knowledge of the new yet common and important diagnostic category of UdH. The findings call for action in national and international health policies, and for further epidemiological research.

Sleep coaching: non-pharmacological treatment of non-restorative sleep in Austrian railway shift workers.

Sleep coaching by Holzinger & Klösch™ is a new, Gestalt therapy-based holistic approach to non-pharmacological treatment of non-restorative sleep. It includes psychotherapeutic aspects which enable participants to improve their sleep quality by developing their own coping strategies as a daily routine. Dream work and relaxation techniques are also part of the programme. The aim of this study was to measure the effectiveness of a two-day sleep coaching seminar on sleep quality, daytime sleepiness, and work and life quality in shift workers employed in an Austrian railway company (Österreichische Bundesbahnen, ÖBB). Thirty shift workers (28 male; mean age=24±45.90, age range 24-56 years) answered the same survey before and six months after the seminar (baseline and follow-up) containing items of the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS), their chronotype, personality factors, and burnout risk factors. The baseline findings in this group were compared with those of non-completers (who did not take the follow-up survey) (N=154) to see if the two groups differed significantly enough to create a bias among completers (who took the follow-up survey as well). Groups differed significantly in burnout levels as well as sleep duration, but not in the distribution of critical PSQI and ESS values. The two-day sleep coaching seminar resulted in a significant improvement in total PSQI score and subjective sleep quality and in a significant reduction in diurnal fatigue, sleep latency, and daytime sleepiness. Nevertheless, more research with a larger sample and a longitudinal design is needed to establish the long-term effects of sleep coaching.

Adherence to inhaled therapy and its impact on chronic obstructive pulmonary disease (COPD).

BACKGROUND: COPD is a treatable disease with increasing prevalence worldwide. Treatment aims to stop disease progression, to improve quality of life, and to reduce exacerbations. We aimed to evaluate the association of the stage of COPD on adherence to inhaled therapy and the relationship between adherence and COPD exacerbations. METHODS: A retrospective analysis of patients hospitalized for acute exacerbation of COPD in a tertiary care hospital in Upper Austria and discharged with a guideline conform inhaled therapy was performed. Follow-up data on medical utilization was recorded for the subsequent 24 months. Adherence to inhaled therapy was defined according to the percentage of prescribed inhalers dispensed to the patient and classified as complete (> 80%), partial (50-80%) or low (< 50%). RESULTS: Out of 357 patients, 65.8% were male with a mean age of 66.5 years and a mean FEV1 of 55.0%pred. Overall, 35.3% were current smokers, and only 3.9% were never-smokers. In 77.0% inhaled triple therapy (LAMA + LABA + ICS) was prescribed. 33.6% showed complete adherence to their therapy (33.2% in men, 34.4% in women), with a mean age of 67.0 years. Mean medication possession ratio by GOLD spirometry class I - IV were 0.486, 0.534, 0.609 and 0.755, respectively (p = 0.002). Hence, subjects with complete adherence to therapy had a significantly lower FEV1 compared to those with low adherence (49.2%pred. vs 59.2%pred., respectively; p <  0.001). The risk of exacerbations leading to hospitalization was 10-fold higher in GOLD spirometry class IV compared to GOLD spirometry class I, which was even more evident in multivariate analysis (OR 13.62). CONCLUSION: Complete adherence to inhaled therapy was only seen in 33.6% and was higher among those with more severe COPD. TRIAL REGISTRATION: Not applicable.

Severe hair loss associated with psychotropic drugs in psychiatric inpatients-Data from an observational pharmacovigilance program in German-speaking countries.

BACKGROUND: The study aimed to investigate severe hair loss related to psychotropic drugs (PDs) by using data from the drug safety programme Arzneimittelsicherheit in der Psychiatrie (AMSP). METHODS: Data on PD utilization and reports of severe PD-related hair loss were collected in 83 psychiatric hospitals in Austria, Germany and Switzerland during the period 1993-2013. RESULTS: Out of 432,215 patients under surveillance, 404,009 patients were treated with PDs for the main indications of depression, schizophrenic disorder, neurosis, mania, and organic psychosis. Severe hair loss related to PD treatment was reported in 43 cases (0.01%). The rates of hair loss under antipsychotic drugs were slightly lower than the mean rates of all PDs and antidepressant drugs. Valproic acid was related to the highest risk. In 6 of the 43 cases, hair loss was imputed to multiple drugs, with 4 cases imputed to double drug combinations and 2 cases to triple combinations. Rates of severe hair loss under valproic acid (VPA) and lithium salts were distinctly lower as compared with the overall rates reported in literature. Severe hair loss under PD treatment was reported significantly more often in female patients than in male patients (p < 0.01). CONCLUSION: The rate of severe PD-related hair loss was very low in the present survey. The large number of patients included in this multicentre study allows for assessment and comparison of hair loss rates related to different PDs and groups of PDs and provides new and supplementary information on PD-related hair loss.

Variability of SCCmec elements in livestock-associated CC398 MRSA.

The most common livestock-associated lineage of methicillin-resistant Staphylococcus aureus (MRSA) in Western Europe is currently clonal complex (CC) 398. CC398-MRSA spread extensively across livestock populations in several Western European countries, and livestock-derived CC398-MRSA strains can also be detected in humans. Based on their SCCmec elements, different CC398 strains can be distinguished. SCCmec elements of 100 veterinary and human CC398-MRSA isolates from Germany and Austria were examined using DNA microarray-based assays. In addition, 589 published SCC and/or genome sequences of CC398-MRSA (including both, fully finished and partially assembled sequences) were analysed by mapping them to the probe sequences of the microarrays. Several isolates and sequences showed an insertion of a large fragment of CC9 genomic DNA into the CC398 chromosome. Fifteen subtypes of SCCmec elements were detected among the 100 CC398 isolates and 41 subtypes could be discerned among the published CC398 sequences. Eleven of these were also experimentally detected within our strain collection, while four subtypes identified in the isolates where not found among the sequences. A high prevalence of heavy metal resistance genes, especially of czrC, was observed among CC398-MRSA. A possible co-selection of resistances to antibiotics and zinc/copper supplements in animal feed as well as a spill-over of SCCmec elements that have evolved in CC398-MRSA to other, possibly more virulent and/or medically relevant S. aureus lineages might pose public health problems in future.

The Gender-Specific Associations Between Religion/Spirituality and Suicide Risk in a Sample of Austrian Psychiatric Inpatients.

Most studies have found religion/spirituality to be protective against suicide risk, with a stronger effect among women. To understand this effect, theories of suicide and clinical samples are needed, but related studies are lacking. We applied two established suicide models in 753 psychiatric inpatients. Religion/spirituality correlated protectively with components of the suicide models, with stronger associations among women. The protective effect emerged especially for the capability aspect of suicide among men and for the motivational aspect among women, suggesting very different causal mechanisms, but this has to be replicated with longitudinal studies.

A ten-year study of midwife-led care at an Austrian tertiary care center: a retrospective analysis with special consideration of perineal trauma.

BACKGROUND: In contrast to other countries, Austria rarely offers alternative models to medical led-care. In an attempt to improve the facilities, a midwife-led care service was incorporated within the Department of Obstetrics and Fetomaternal Medicine. The aim of the present study was to analyze the maternal and neonatal outcomes of this approach. METHODS: Over a 10-years period, a total of 2123 low-risk women receiving midwife-led care were studied. Among these women, 148 required obstetric referral. Age- and parity matched low-risk women with spontaneous vaginal birth overseen by an obstetrician-led team were used as controls to ensure comparability of data. RESULTS: Midwife-led care management demonstrated a significant decrease in interventions, including oxytocin use (p < 0.001), medical pain relief (p < 0.001), and artificial rupture of membranes (ARM) (p < 0.01) as well as fewer episiotomies (p < 0.001), as compared with obstetrician-led care. Moreover, no negative effects on maternal or neonatal outcomes were observed. The mean length of the second stage of labor, rate of perineal laceration and APGAR scores did not differ significantly between the study groups (p > 0.05). Maternal age (p < 0.01), head diameter (p < 0.001), birth weight (p < 0.001) and the absence of midwife-led care (p < 0.05) were independent risk factors for perineal trauma. The overall referral rate was low (7%) and was most commonly caused by pathologic cardiotocography (CTG) and prolonged first- and second-stage of labor. Most referred mothers nevertheless had spontaneous deliveries (77%), and there were low rates of vaginal operative deliveries and cesarean sections (vacuum extraction, 16%; cesarean section, 7%). CONCLUSIONS: The present study confirmed that midwife-led care confers important benefits and causes no adverse outcomes for mother and child. The favorable obstetrical outcome clearly highlights the importance of the selection of obstetric care, on the basis of previous risk assessment. We therefore fully support the recommendation that midwife-led care be offered to all low-risk women and that mothers should be encouraged to use this option. However, to increase the numbers of midwife-led care deliveries in Austria in the future, it will be necessary to expand this care model and to establish new midwife-led care units within hospital facilities.

Revised Reference Values for Potassium Intake.

BACKGROUND: The nutrition societies of Germany, Austria and Switzerland have revised the reference values for potassium intake in January 2017. METHODS: For adults, the estimated value was based on the 24-h urinary potassium excretion and on preventive considerations regarding hypertension and stroke. The estimated values for children and adolescents were extrapolated from the adult estimated value considering differences in body mass. For infants aged 0 to under 4 months, the estimated value was set based on the potassium intake via breast milk. From this reference value, the estimated value for infants aged 4 to under 12 months was also derived by extrapolation. The estimated value for lactating women takes into account the potassium loss via breast milk. RESULTS: The estimated values for potassium intake are set at 400 mg/day for breastfed infants aged 0 to under 4 months, 600 mg/day for infants aged 4 to under 12 months, 1,100-4,000 mg/day for children and adolescents, 4,000 mg/day for adults and pregnant women and 4,400 mg/day for lactating women. CONCLUSIONS: The consumption of potassium-rich foods should be generally increased. Supplemental intake beyond the estimated values has no health benefit and is therefore not recommended.

Age-related prevalence of osteoporosis and fragility fractures: real-world data from an Austrian Menopause and Osteoporosis Clinic.

OBJECTIVES: Age and bone mineral density (BMD) are the most relevant determinants for public health authorities to govern the management of osteoporosis. The objectives of this study were to determine the age-related prevalence of osteopenia and osteoporosis according to WHO criteria and fragility fractures in middle-aged and older women. METHODS: Women ≥40 years, who were referred to a menopause and osteoporosis outpatient clinic for BMD measurements, were assessed for patient characteristics, BMD and previous fragility fractures of the hip, the distal forearm and the vertebrae. Only records of their initial consultations were used for data analysis. RESULTS: Between 1990 and 2012, 99,399 women, mean age 56.1 years, were referred to the clinic for BMD testing. Of the total population, 52.5% showed normal, 34.0% osteopenic and 13.5% osteoporotic BMD. Fragility fractures were reported by 6540 patients, with 3070 (47%) non-vertebral fractures, namely 2518 (38.5%) distal forearm and 552 (8.4%) hip fractures; 66.8% of patients with the non-vertebral fractures were <65 years. CONCLUSION: The prevalence of osteoporosis and fragility fractures in middle-aged women, < 65 years, is hitherto under-recognized. Measuring BMD alone is not sufficient to identify patients at risk for fractures. Supplemental screening for clinical risk factors already during perimenopause may be advantageous.

The medical and scientific responsibility of pollen information services.

Pollen information as such is highly valuable and was considered so far as a self-evident good free for the public. The foundation for reliable and serious pollen information is the careful, scientific evaluation of pollen content in the air. However, it is essential to state and define now the requirements for pollen data and qualifications needed for institutions working with pollen data in the light of technical developments such as automated pollen counting and various political interests in aerobiology including attempts to finally acknowledge pollen and spores as relevant biological particles in the air worth being considered for pollution and health directives. It has to be emphasized that inadequate pollen forecasts are a considerable health risk for pollen allergy sufferers. Therefore, the responsibility of institutions involved in pollen monitoring and forecasting is high and should be substantiated with respective qualifications and know-how. We suggest here for the first time a portfolio of quality criteria and demand rigorous scientific monitoring and certification of such institutions in the interest and for the protection of persons affected by a pollen allergy.

Potential drug-drug interactions and adverse drug reactions in dermatological inpatients.

OBJECTIVES: To present information on the frequency of drug-drug interactions and adverse drug reactions, and to provide assistance on how to minimize these major problems in the pharmacological treatment of dermatological inpatients. PATIENTS AND METHODS: The medications given to 1,099 dermatological inpatients were retrospectively analyzed for drug-drug interactions and adverse drug reactions using web-based drug interaction software (Diagnosia® Check). RESULTS: We report an overall frequency of relevant drug-drug interactions of 51.7 %, with an average of 3.2 interactions per affected inpatient. Drug combinations that should have been avoided were found in 5.7 % of the study population. Total drug count was the most important risk factor. Drug groups involved in the majority of interactions were analgesics, cardiovascular and antithrombotic agents, as well as antidepressants. The risk of developing adverse drug reactions was rated as "high" in 53.1 % of inpatients. The top five adverse reactions in this patient group were bleeding, constipation, anticholinergic effects, sedation, and orthostatic effects. CONCLUSIONS: Potential drug-drug interactions as well as adverse drug reactions are alarmingly common in dermatological inpatients. Every other patient is at risk of experiencing such interactions or adverse reactions, and every twentieth patient receives a drug combination that should not be administered. Increased alertness is a must in order to identify patients at risk.

Elucidation of enterotoxigenic Bacillus cereus outbreaks in Austria by complementary epidemiological and microbiological investigations, 2013.

Identifying Bacillus cereus as the causative agent of a foodborne outbreak still poses a challenge. We report on the epidemiological and microbiological investigation of three outbreaks of food poisoning (A, B, and C) in Austria in 2013. A total of 44% among 32 hotel guests (A), 22% among 63 employees (B) and 29% among 362 residents of a rehab clinic (C) fell sick immediately after meal consumption. B. cereus isolated from left overs or retained samples from related foods were characterized by toxin gene profiling, and molecular typing using panC sequencing and M13-PCR typing (in outbreak A and C). We identified two B. cereus strains in outbreak A, and six B. cereus strains, each in outbreak B and C; we also found Staphylococcus aureus and staphylococcal enterotoxins in outbreak A. The panC sequence based phylogenetic affiliation of the B. cereus strains, together with findings of the retrospective cohort analyses, helped determining their etiological role. Consumption of a mashed potatoes dish in outbreak A (RR: ∞), a pancake strips soup in outbreak B (RR 13.0; 95% CI 1.8-93.0) and for outbreak C of a fruit salad (RR 1.50; 95% CI 1.09-2.00), deer ragout (RR: 1.99; 95% CI 1.23-3.22) and a cranberry/pear (RR 2.46; 95% CI 1.50-4.03)were associated with increased risk of falling sick. An enterotoxigenic strain affiliated to the phylogenetic group with the highest risk of food poisoning was isolated from the crème spinach and the strawberry buttermilk, and also from the stool samples of the one B. cereus positive outbreak case-patient, who ate both. Our investigation of three food poisoning outbreaks illustrates the added value of a combined approach by using epidemiological, microbiological and genotyping methods in identifying the likely outbreak sources and the etiological B. cereus strains.

Do Patients After Chondrosarcoma Treatment Have Age-appropriate Bone Mineral Density in the Long Term?

BACKGROUND: In long-term survivors of osteosarcoma and Ewing sarcoma treated with the addition of radio- and chemotherapy, low bone mineral density (BMD) and fractures have been observed, presumably resulting from these adjuvants. Because patients with chondrosarcoma usually are not treated with conventional adjuvant treatment, observation of low BMD in patients with chondrosarcoma presumably would be the result of other mechanisms. However, BMD in patients with a history of chondrosarcoma has not been well characterized. QUESTIONS/PURPOSES: The aim of our study was to address the following questions: (1) Do long-term survivors of chondrosarcoma have normal BMD and, if not, which factors contribute to low BMD? (2) Is there a greater risk of fracture and does the Fracture Risk Assessment Tool (FRAX(®)) score reflect fracture likelihood? METHODS: All known patients with a history of chondrosarcoma treated at our institution before 2006 were identified. Of 127 patients believed to be alive at the time of this study, 30 agreed to participate in this study (11 females, 19 males; mean age at surgery, 39 ± 12 years; mean followup, 12 ± 5 years). With the data available, the 30 participants were not different from the 97 nonparticipants in terms of age, sex, BMI, tumor grade, tumor location (axial versus appendicular, lower extremity versus elsewhere), and use of any treatment known to influence osteopenia (chemotherapy, lower extremity surgery). BMD was measured and history of fractures was assessed using a questionnaire. The patients´ BMD measurements in this study were sex- and age-matched with a normative sex- and age-categorized reference population reported by Kudlacek et al. Associations were tested by univariate regressions and ANOVAs of all measures of BMD and eligible oncologic and demographic factors. RESULTS: Eighteen of 30 (60%) patients had a pathologic BMD according to the WHO dual-energy x-ray absorptiometry definition, 15 (50%) had osteopenia, and three (10%) had osteoporosis. T-scores in the study cohort were lower than reference values for the femur neck (mean difference, 0.64; 95% CI, 0.27-1.01; p < 0.0015), but not for the spine (mean difference, 0.39; 95% CI, -0.06 to 0.84; p = 0.09). Thirteen patients (45%) reported a history of fractures not distinguishing between low and high impact. The incidence of fractures was 2.8 greater than expected from a comparison with a published microcensus survey of the Austrian population. No effect of the FRAX(®) score on fracture risk could be identified (p = 0.057). CONCLUSIONS: Long-term survivors of chondrosarcoma appear to be at greater risk for having low BMD develop than the healthy population. Although these results are preliminary and based on a very small sampling of patients, if they can be confirmed in larger studies, BMD assessment by dual-energy x-ray absorptiometry might be considered as these patients are followed posttreatment by sarcoma care units. The reasons for low BMD still must be elucidated. LEVEL OF EVIDENCE: Level IV, prognostic study.

First comparison of symptom data with allergen content (Bet v 1 and Phl p 5 measurements) and pollen data from four European regions during 2009-2011.

BACKGROUND: The level of symptoms in pollen allergy sufferers and users of the Patient's Hayfever Diary (PHD), does not directly reflect the total amount of pollen in the air. It is necessary to explain the symptom load and thus the development of allergic symptoms and to determine which environmental factors, besides the pollen load, influence variables. It seems reasonable to suspect allergen content because the amount of allergen varies throughout seasons and regions and is not always correlated with the total pollen amount. METHODS: Data on the allergen content of ambient air (Bet v 1 and Phl p 5) from 2009 until 2011 was used to compare the respective pollen and symptom loads for study regions in Austria, Germany, France and Finland. RESULTS: Our findings suggest that allergen amount (Bet v 1/Phl p 5) has a strong but regionally dependent impact on the symptom load of pollen allergy sufferers. Peak symptom loads can be traced with peak allergen loads. The influence of other important aeroallergens should also be assessed during the pollen season. CONCLUSION: Allergen concentrations have an impact on pollen allergy sufferers although not as clear as assumed previously. The pattern of pollen load and major allergen content distribution does not directly explain the symptom load pattern, although significant positive correlations were found. Thus, monitoring of symptoms via voluntary crowdsourcing should be considered for future pollen and symptom forecasts in order to support pollen allergy sufferers.
