Abstract
BACKGROUND AND OBJECTIVE Among many treatment approaches for chronic low back pain (CLBP), self-management techniques are becoming increasingly important. The aim of this paper was to (a) provide an overview of existing digital self-help interventions for CLBP and (b) examine the effect of these interventions in reducing pain intensity, pain catastrophizing and pain disability. DATABASES AND DATA TREATMENT Following the PRISMA guideline, a systematic literature search was conducted in the MEDLINE, EMBASE, PsychInfo, CINAHL and Cochrane databases. We included randomized controlled trials from the last 10 years that examined the impact of digital self-management interventions on at least one of the three outcomes in adult patients with CLBP (duration ≥3 months). The meta-analysis was based on random-effects models. Standardized tools were used to assess the risk of bias (RoB) for each study and the quality of evidence for each outcome. RESULTS We included 12 studies (n = 1545). A small but robust and statistically significant pooled effect was found on pain intensity (g = 0.24; 95% CI [0.09, 0.40], k = 12) and pain disability (g = 0.43; 95% CI [0.27, 0.59], k = 11). The effect on pain catastrophizing was not significant (g = 0.38; 95% CI [-0.31, 1.06], k = 4). The overall effect size including all three outcomes was g = 0.33 (95% CI [0.21, 0.44], k = 27). The RoB of the included studies was mixed. The quality of evidence was moderate or high. CONCLUSION In summary, we were able to substantiate recent evidence that digital self-management interventions are effective in the treatment of CLBP. Given the heterogeneity of interventions, further research should aim to investigate which patients benefit most from which approach. SIGNIFICANCE This meta-analysis examines the effect of digital self-management techniques in patients with CLBP. The results add to the evidence that digital interventions can help patients reduce their pain intensity and disability. A minority of studies point towards the possibility that digital interventions can reduce pain catastrophizing. Future research should further explore which patients benefit most from these kinds of interventions.

Abstract
PURPOSE The European Organisation for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (QLQ-C30) is a validated and widely-used Patient-Reported Outcome Measure for measuring the health-related quality of life (HRQoL) of cancer patients. To facilitate interpretation of results obtained in studies using the EORTC QLQ-C30, we generated normative data for the Dutch general population, stratified by age and sex. METHODS Dutch participants were selected from a larger cross-sectional online panel research study collecting EORTC QLQ-C30 general population normative data across 15 countries. EORTC QLQ-C30 raw scores based on a 4-point response scale were transformed to linear scores ranging from 0 to 100. Transformed scores were weighted based on the United Nations population distribution statistics and presented by age and sex/age. Differences in scale scores of ≥ 10 points in HRQoL were applied to indicate clinical relevance. RESULTS One thousand respondents completed the online survey. Stratified by age, clinically meaningful differences were observed, with worse physical functioning scores and better emotional functioning scores with increased age. Symptom scores remained stable across age groups, except for small age differences observed for fatigue, nausea/vomiting, diarrhoea, and financial difficulties. Stratified by sex/age, men generally scored better for both functioning and symptoms. However, these differences were not clinically meaningful. CONCLUSIONS These updated normative EORTC QLQ-C30 for the Dutch general population can be used to better interpret HRQoL data obtained from Dutch cancer patients. Being part of a larger international study, these data can further be used for inter-country comparisons in multi-national studies.

Abstract
OBJECTIVE The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 health-related quality of life questionnaire is one of the most widely used cancer-specific health-related quality of life questionnaires worldwide. General population norm data can facilitate the interpretation of QLQ-C30 data obtained from cancer patients. This study aimed at systematically collecting norm data from the general population to develop European QLQ-C30 norm scores and to generate comparable norm data for individual countries in Europe and North America. METHODS We collected QLQ-C30 data from the general population across 11 European Union (EU) countries, Russia, Turkey, Canada and United States (n ≥ 1000/country). Representative samples were stratified by sex and age groups (18-39, 40-49, 50-59, 60-69 and ≥ 70 years). After applying weights based on the United Nations population distribution statistics, we calculated QLQ-C30 domain scores to generate a 'European QLQ-C30 Norm' based on the EU countries. Further, we calculated QLQ-C30 norm scores for all 15 individual countries. RESULTS A total of 15,386 respondents completed the online survey. For the EU sample, most QLQ-C30 domains showed differences by sex/age, with men scoring somewhat better health than women, while age effects varied across domains. Substantially larger differences were seen in inter-country comparisons, with Austrian and Dutch respondents reporting consistently better health compared with British and Polish respondents. CONCLUSIONS This study is the first to systematically collect EORTC QLQ-C30 general population norm data across Europe and North America applying a consistent data collection method across 15 countries. These new norm data facilitate valid intra-country as well as inter-country comparisons and QLQ-C30 score interpretation.

Abstract
Human granulocytic ehrlichiosis (HGE) is an emerging infectious disease recognized in the Western hemisphere. HGE is well known to occur in North America, but records from outside the United States are sparse. The great majority of data from Europe are restricted to seroprevalence studies and molecular biological detection of granulocytic ehrlichiae (GE) in ticks and mammals, but include defined cases from Slovenia. They argue for the existence of this disease in many parts of Europe. In the present study, 510 Ixodes ricinus ticks collected in five different regions of Southern Germany were investigated for the presence of GE and Borrelia burgdorferi sensu lato using polymerase chain reaction. In all, 8 (1.6%) of the 492 ticks that could be evaluated (193 females, 208 males, and 91 nymphs) contained GE and 178 (36.2%) B. burgdorferi s.l.. Four of these ticks were infected with both pathogens. Interestingly, all ehrlichia-infected ticks were adults and all were collected in the English Garden, a recreational park area located in the city of Munich. Sequencing of the 16S rDNA (bp 1 1101) of four of the GE showed 100% sequence identity to each other and greater than 99.9% identity with the published sequence of the HGE agent. The four GE differed in respect to other hitherto described GE by a nucleotide exchange at position 336. These results show that GE that are closely related to the HGE agent are present in Southern Germany, and that coinfection with B. burgdorferi is common in GE-infected ticks. However, in contrast to B. burgdorferi which is endemic everywhere in Southern Germany, the distribution of GE seems to be focal.

Abstract
A total of 131 Ixodes ricinus (51 females, 1 male and 79 nymphs) removed from persons living in Southern Germany were investigated by immunofluorescence assay for the presence of Borrelia burgdorferi with a polyvalent rabbit immune serum and monoclonal antibodies specific for outer surface proteins (Osp) A or C. Borreliae were detectable in 48 (36.6%) of the ticks. Infection rates of these adults and nymphs were significantly higher than infection rates of unfed ticks from Southern Germany. Borreliae in 31.3% (n=15) of the infected ticks expressed solely OspA, solely OspC in 12.5% (n=6), and both OspA and OspC in 39.6% (n=19) of ticks, while in 16.7% (n=8) of ticks neither were expressed. Presentation of OspC by B. burgdorferi in I. ricinus was correlated with tick weight: in females, OspC was detectable only in ticks with a minimum weight of about 3.5 mg, and in nymphs weighing at least 1 mg. These results indicate that in I. ricinus removed from humans OspC is up-regulated during the blood meal of the tick, but in most ticks OspA is still detectable and might even be present in the absence of OspC expression in the midgut and salivary glands of nearly fully engorged nymphal ticks. Furthermore, we found strong evidence that borreliae expressing solely OspA while in the salivary glands can cause Lyme borreliosis. Our findings indicate that during tick feeding, humans are exposed to borreliae that may express either OspA or OspC or both, or lack both OspA and C. These findings suggests that, at the minimum, both OspA and C should be considered as vaccine candidates for prophylaxis of Lyme borreliosis in Europe.

Abstract
A total of 472 field-collected Ixodes ricinus ticks from southern Germany were investigated by immunofluorescence for the presence of Borrelia burgdorferi with a polyvalent rabbit immune serum and with monoclonal antibodies specific for outer surface proteins A and C (OspA and OspC, respectively). Borreliae were detected in 90 ticks with the polyvalent immunofluorescence assay. Infection rates in adults (females, 20.2%; males, 25.2%) were significantly higher than in nymphs (12.1%). OspA was detected in 77 ticks and OspC was detected in only 1 tick with the respective monoclonal antibodies. We therefore conclude that B. burgdorferi in unfed I. ricinus ticks usually expresses OspA and very rarely OspC.

Abstract
It has been shown by analysis with monoclonal and polyclonal antibodies that outer surface protein C (OspC) of Borrelia burgdorferi sensu lato is highly heterogeneous. To determine if the heterogeneity has a genetic basis, the genes of 18 different B. burgdorferi sensu lato strains have been amplified by PCR, cloned, and sequenced. The ospC genes could be amplified from all strains tested, even from two strains which did not express OspC in detectable amounts. Among the 18 strains, 16 significantly different types of ospC sequences have been found. The sequence identities of the deduced amino acid sequences of different ospC genotypes range between 62 and 80% (determined without the leader peptide). The sequences range between 62 and 80% (determined without the leader peptide). The sequences correspond to one of the 13 OspC types distinguishable by analysis with monoclonal antibodies (B. Wilske, S. Jauris-Heipke, R. Lobentanzer, I. Pradel, V. Preac-Mursic, D. Roessler, E. Soutschek, and R. C. Johnson, J. Clin. Microbiol. 33:103-109, 1995) or represent additional types. Two completely new types were found, and OspC type 8 (which was found in Borrelia afzelii and Borrelia garinii) could be divided into two groups with different sequences but the same antibody pattern. Thus, strains belonging to different species or OspA serotypes were always significantly different in their ospC sequences. This was also confirmed by ospA sequence analysis. Interestingly, some strains of the same OspA serotype or genotype were very heterogeneous with respect to OspC, while others had nearly identical OspC proteins. Such groups of strains were found among B. burgdorferi sensu stricto, B. afzelii, and B. garinii strains. Cluster analysis of 5'-terminal and 3'-terminal stretches of ospC suggested recent intragenic recombination events in the ospC gene at least one B. afzelii strain. In addition, other recombination events between ancestors of strains belonging to the same or different species were evidenced by this type of analysis.
