[Percutaneous stabilization of the anterior pelvic ring in osteoporotic fractures]. / Perkutane Stabilisierung bei osteoporotischen Frakturen des vorderen Beckenrings.

The number of low energy traumas in older people with subsequent pelvic ring fractures is increasing in contrast to high energy traumas with pelvic injury in younger people. Geriatric pelvic fractures can be treated conservatively with analgesics and physiotherapy-assisted mobilization, depending on the symptoms. If physical complaints do not allow adequate mobilization, surgical stabilization is indicated. It is often possible to stabilize the dorsal pelvic ring with transiliosacral screws. If additional instability associated with anterior pelvic ring complaints is prevalent, stabilization of the anterior ring can be achieved by invasive osteosynthesis using a plate or percutaneously by implanting an intramedullary plastic polymer.

Head coaches' attitudes towards injury prevention and use of related methods in professional basketball: A survey.

OBJECTIVES: To investigate the practices and attitudes of professional basketball head coaches towards injury prevention. DESIGN: Survey. SETTING: Elite-level basketball. PARTICIPANTS: Head coaches of all 366 German professional teams. MAIN OUTCOME MEASURES: Use of injury risk screening methods, rated importance of different musculoskeletal injuries and rated effectiveness of preventive interventions. RESULTS: Eighty-three of 366 invited coaches (23%) responded to the survey. No non-response bias was detected. Only one of three teams conducts systematic injury screenings. The most commonly used test was the functional movement screen (73.1% of users), while balance and strength testing (both 38.5%) were least prevalent. Top-rated preventive interventions included balance and strength training, training of functional movement patterns, and stretching. In contrast, passive interventions, e.g. the use of orthoses, were not considered effective. The involvement of a health professional (e.g. physiotherapist) was associated with the performance of injury screening, but not with the choice of specific tests or preventive strategies. CONCLUSIONS: The methods applied to conduct injury screening and prevent musculoskeletal disorders in German professional basketball teams seem only partially backed by scientific evidence. Although not correlated with the tests and interventions used, the involvement of health-related stakeholders might help to identify players at increased injury risk.

Needle biopsy-derived myofascial tissue samples are sufficient for quantification of myofibroblast density.

Quantification of myofibroblasts is a promising method for assessing tissue properties in the field of fascia research. This is commonly performed by immunohistochemistry for α-smooth muscle actin. However, usually larger tissue samples sizes are required for quantification. The aim of this investigation was to explore whether a microscopic quantification of myofibroblasts can be conducted with fascial tissue samples derived via percutaneous needle biopsy. Fascial tissues were derived via percutaneous needle biopsy from the fascia lata of 11 persons (aged 19-40 years). Following immunohistochemistry, selected fields for photomicroscopic analysis were chosen by a Monte Carlo method based randomization procedure. On these fields, a digital quantification for the relative density of α-smooth muscle actin was attempted. The newly developed quantification method could successfully be applied in all tissue samples. The median α-smooth muscle actin density in the selected tissue samples ranged between 0% and 1.7% (median 0%, IQR 0%-0.001%). The applied protocol proved to be workable for the purpose of an estimation of the α-smooth muscle actin density in fascial tissue samples derived via percutaneous needle biopsy. Since this type of biopsy is less invasive than the commonly performed open muscle biopsy, this offers a new and useful perspective for future histological investigations of fascial tissue properties in living patients.

Is remote stretching based on myofascial chains as effective as local exercise? A randomised-controlled trial.

Lower limb stretching based on myofascial chains has been demonstrated to increase cervical range of motion (ROM) in the sagittal plane. It is, however, unknown whether such remote exercise is as effective as local stretching. To resolve this research deficit, 63 healthy participants (36 ± 13 years, ♂32) were randomly assigned to one of three groups: remote stretching of the lower limb (LLS), local stretching of the cervical spine (CSS) or inactive control (CON). Prior (M1), immediately post (M2) and 5 min following intervention (M3), maximal cervical ROM was assessed. Non-parametric data analysis (Kruskal-Wallis tests and adjusted post hoc Dunn tests) revealed significant differences between the disposed conditions. With one exception (cervical spine rotation after CSS at M2, P > .05), both LLS and CSS increased cervical ROM compared to the control group in all movement planes and at all measurements (P < .05). Between LLS and CSS, no statistical differences were found (P > .05). Lower limb stretching based on myofascial chains induces similar acute improvements in cervical ROM as local exercise. Therapists might consequently consider its use in programme design. However, as the attained effects do not seem to be direction-specific, further research is warranted in order to provide evidence-based recommendations.

Range of motion and cervical myofascial pain.

Several studies investigating myofascial pain syndrome include assessments of range of motion (ROM) as a diagnostic criterion. However, the value of ROM in this context has not yet been evaluated in controlled clinical studies. We aimed to examine whether patients with myofascial pain syndrome display alterations of ROM when compared to healthy subjects. Twenty-two individuals (13 females, 9 males; aged 33.4 ± 13.9 yrs) afflicted with active myofascial trigger points in the upper trapezius muscle as well as 22 age and sex matched healthy controls were included. All subjects underwent an examination of maximal active cervical ROM in flexion/extension assessed by means of a 3D ultrasonic movement analysis system (30 Hz; Zebris CMS 70). In the patients group, pressure pain threshold (PPT) of the trigger points was determined using a pressure algometer. Maximum range of motion in the sagittal plane did not differ between individuals with MTrP (125.9 ± 23.2°, 95% CI: 116.2-135.6°) and asymptomatic subjects (128.2 ± 20.4°, 95% CI: 119.7-136.7°; p > .05). In patients, PPT (1.7 ± .6, 95% CI: 1.5-1.9) was not correlated with cervical mobility (r = -.13; p > .05). Based on these pilot data, range of motion in flexion/extension is not a valid criterion for the detection of myofascial trigger points. Additional research incorporating movement amplitudes in other anatomical planes and additional afflicted muscles should be conducted in order to further delineate the relative impact of MTrP on range of motion.

Children's snack consumption: role of parents, peers and child snack-purchasing behaviour. Results from the INPACT study.

BACKGROUND: Parents and peers are both likely to influence children's dietary behaviour. However, their actual influence may depend on the age and life stage of the individual child. Therefore, this study examined the influence of parents (home snack availability and consumption rules) and peers on 11-year-old children's snack consumption, and whether these associations were mediated by children's snack-purchasing behaviour. It was hypothesized that children are more likely to buy unhealthy snacks if these are not always available at home, if restrictive rules apply to their consumption and if a child is sensitive to peer influence. It was also assumed that children who buy snacks out of their pocket money would consume more snacks. METHODS: Data were taken from 1203 parent-child dyads who completed a questionnaire in the INPACT study (IVO Physical Activity Child cohorT). Multivariable regression models were used to (i) analyze associations between children's consumption and parents' and peers' influence and (ii) determine whether these associations were mediated by children's snack-purchasing behaviour. RESULTS: Of the parental factors, home availability of snacks was associated with higher snack consumption (B = 1.03, P < 0.05). Parental factors and children's snack-purchasing behaviour were not associated. Children who were sensitive to peer influence consumed more snacks (B = 3c07, P < 0.01) and bought more snacks out of their pocket money (odds ratio 3.27, P < 0.0.01). Children's snack-purchasing behaviour explained part (8.6%) of the association between peer influence and children's snack consumption. CONCLUSION: As these findings indicate that both parents and peers influence children's snack consumption, health promotion may benefit from targeting the broader social environment.

Appraising the methodological quality of cadaveric studies: validation of the QUACS scale.

Although systematic reviews are conducted in the field of anatomical research, no instruments exist for the assessment of study quality. Thus, our objective was to develop a valid tool that reliably assesses the methodological quality of observational cadaveric studies. The QUACS scale (QUality Appraisal for Cadaveric Studies) was developed using an expert consensus process. It consists of a 13-item checklist addressing the design, conduct and report of cadaveric dissection studies. To evaluate inter-rater reliability, a blinded investigator obtained an initial pool of 120 observational cadaveric studies. Sixty-eight of them were selected randomly according to sample size calculations. Three independent researchers rated each publication by means of the QUACS scale. The reliability of the total score was estimated using the intraclass correlation coefficient (ICC). To assess agreement among individual items, margin-free kappa values were calculated. For construct validity, two experts (an anatomist and an experienced physician) categorized the quality of 15 randomly selected studies as 'excellent' (4 points), 'moderate to good' (3 points), poor to moderate' (2 points) or 'poor' (1 point). Kendall's tau rank correlation was used to compare the expert ratings with the scores on the QUACS scale. An evaluation of feasibility was carried out during the reliability analysis. All three raters recorded the duration of quality appraisal for each article. Means were used to describe average time exposure. The ICC for the total score was 0.87 (95% confidence interval: 0.82-0.92; P < 0.0001). For individual items, margin-free kappa values ranged between 0.56 and 0.96 with an agreement of 69-97% among the three raters. Kendall's tau B coefficient of the association between expert ratings and the results obtained with the QUACS scale was 0.69 (P < 0.01). Required rating time per article was 5.4 ±â€…1.6 min. The QUACS scale is highly reliable and exhibits strong construct validity. Thus, it can confidently be applied in assessing the methodological quality of observational dissection studies.

Short-term effects of acupuncture and stretching on myofascial trigger point pain of the neck: a blinded, placebo-controlled RCT.

OBJECTIVES: This trial aimed to evaluate the short-term effectiveness of acupuncture plus stretching to reduce pain and improve range of motion in patients afflicted by cervical myofascial pain syndrome. DESIGN: Randomized, blinded, placebo-controlled crossover study. INTERVENTION: Nineteen patients (11 females, eight males, 33 ± 14 years) with myofascial neck pain in randomized order received the following treatments with one week washout between: acupuncture, acupuncture plus stretching, and placebo laser acupuncture. MAIN OUTCOME MEASURES: Mechanical pain threshold (MPT, measured with a pressure algometer) represented the primary outcome. Secondary outcomes were motion-related pain (Visual Analogue Scale, VAS) and cervical range of motion (ROM, recorded by means of an ultrasonic 3D movement analysis system). Outcomes were assessed immediately prior as well as 5, 15 and 30 min post treatment. Friedman tests with post hoc Bonferroni-Holm correction were applied to compare differences between treatments. RESULTS: Both acupuncture as well as acupuncture plus stretching increased MPT by five, respectively, 11 percent post treatment. However, only acupuncture in combination with stretching was superior to placebo (p<0.05). There were no significant differences between interventions at 15 and 30 min post treatment. VAS did not differ between treatments at any measurement. Five minutes after application of acupuncture plus stretching, ROM was significantly increased in the frontal and the transversal plane compared to placebo (p<0.05). CONCLUSIONS: The combination of acupuncture and stretching could represent a suitable treatment option to improve cervical movement behavior and reduce trigger point pain in the short-term. However, additional studies further discriminating the placebo effects are still warranted.

[Sporting loads to Spondylodesis of lumbar spine: The return-to-play process]. / Sportliche Belastungen nach Spondylodesen der Lendenwirbelsäule : Der Return-to-play-Prozess.

BACKGROUND: Return to play (RTP) and competition following spinal fusion is of particular importance for athletes. There is a lack of guidelines for decision making in RTP processes. OBJECTIVE: The purpose of this work was to provide a systematic review of the criteria and time of return in the RTP decision process for adults undergoing lumbar spinal fusion. METHODS: Two independent investigators searched MEDLINE using MeSH terms. Targeted outcomes were criteria for return to play decisions and total duration of the RTP process. RESULTS: So far, no prospective randomized controlled trials on RTP after spinal fusion considering inclusion and exclusion criteria are available. Five of the included studies are based on original data. Most of the identified studies are narrative reviews and, thus, exhibit low evidence levels. In addition to the narrative reviews, one observational study, two expert opinion surveys and two model development studies were found. CONCLUSION: Based on the literature research, a positive RTP decision can be made if the following criteria are fulfilled: (1) anatomical and functional healing is complete, (2) safety of the athlete and secondary subjects during training and competition is guaranteed, (3) sport-specific skills are regained, and (4) patient is psychosocially ready. The RTP process can often be successfully initiated 6 months after surgery; some patients however, will never manage the return to full-contact sports and/or sports with risk of collision.

Socio-economic inequalities in children's snack consumption and sugar-sweetened beverage consumption: the contribution of home environmental factors.

In the present study, we examined the association between maternal education and unhealthy eating behaviour (the consumption of snack and sugar-sweetened beverages (SSB)) and explored environmental factors that might mediate this association in 11-year-old children. These environmental factors include home availability of snacks and SSB, parental rules about snack and SSB consumption, parental intake of snacks and SSB, peer sensitivity and children's snack-purchasing behaviour. Data were obtained from the fourth wave of the INPACT (IVO Nutrition and Physical Activity Child cohorT) study (2011), in which 1318 parent-child dyads completed a questionnaire. Data were analysed using multivariate regression models. Children of mothers with an intermediate educational level were found to consume more snacks than those of mothers with a high educational level (B= 1·22, P= 0·02). This association was not mediated by environmental factors. Children of mothers with a low educational level were found to consume more SSB than those of mothers with a high educational level (B= 0·63, P< 0·01). The association between maternal educational level and children's SSB consumption was found to be mediated by parental intake of snacks and SSB and home availability of SSB. The home environment seems to be a promising setting for interventions on reducing socio-economic inequalities in children's SSB consumption.

[Quality of fundamental movement patterns in chronic low back pain patients: a quasi-experimental cross-sectional study]. / Qualität grundlegender Bewegungsmuster bei Patienten mit chronischen lumbalen Rückenschmerzen: Eine quasi-experimentelle Querschnittsstudie.

BACKGROUND: Chronic back pain may be associated with alterations of motor control and maladaptive movement. However, instruments that systematically screen fundamental movement patterns are rare. Using a newly developed functional movement analysis, this study aims to examine whether persons with chronic unspecific low back pain display altered quality of fundamental movement patterns and whether asymmetry exists between body sides. SUBJECTS/METHODS: 20 patients with chronic back pain (♀ = 8, ♂ = 12; 49.4 ±â€Š11.3 years) and 20 healthy controls (♀ = 12, ♂ = 8; 47.7 ±â€Š10.7 years) completed the functional movement analysis. It consists of 11 items screening movements of daily life. Eight of them were to complete left and right. The overall score and the number of observed asymmetries (in items to complete left and right) constituted the primary outcomes. A preliminary analysis of reliability (four raters, four subjects) with pilot character was conducted using intraclass correlation (ICC). To compare differences in means, independent t-tests were performed. In case of significance, we calculated the effect size (Cohen's d). RESULTS: The reliability analysis showed an ICC (2.1) of 0.82 (95 % CI: 0.72 - 0.90). Patients with chronic low back pain (31.95 ±â€Š5.82) scored significantly lower than healthy subjects (44.01 ±â€Š5.27; p < 0.001, d = 2.17). Additionally, patients averaged 3.8 ±â€Š1.28 asymmetries while pain-free participants only demonstrated 1.4 ±â€Š0.94 (p < 0.001; d = 2.14). CONCLUSION: Faulty and dysbalanced movement patterns appear to be linked to chronic low back pain. Nonetheless, given an existing relation, it remains unclear whether the detected deficiencies are causes or consequences of pain. Further studies about the reliability of the presented screening tool are needed.

[Coronary sinus devices for treatment of functional mitral valve regurgitation. Solution or dead end?]. / Koronarsinus-Devices zur Behandlung der funktionellen Mitralklappeninsuffizienz. Ausweg oder Sackgasse?

In this article we review the currently available data on percutaneous mitral valve annulorrhaphy devices using the coronary sinus in patients with functional mitral valve regurgitation (MR). Of these devices the greatest clinical experience exists for the Carillon mitral contour system which has gained increasing application also outside trials in the last 2 years. The advantages include the ease of use with an effective reduction in functional MR and a subsequent improvement of echocardiographic and clinical parameters. A limitation is the compromise of flow in the circumflex artery in some patients especially with a crossing of the coronary sinus with this artery. Future investigations need to focus on the evaluation of this coronary sinus-based technology versus mitral valve clipping technology for the treatment of functional MR.

Is there an association between the home food environment, the local food shopping environment and children's fruit and vegetable intake? Results from the Dutch INPACT study.

OBJECTIVE: To examine: (i) the association between home availability of fruit and vegetables and children's fruit and vegetable intake; (ii) the association between parental perception of the local food shopping environment and the home availability of fruit and vegetables; and (iii) whether the home availability of fruit and vegetables mediates the association between parental perception of the local food environment and children's fruit and vegetable consumption. DESIGN: Cross-sectional study. SETTING: A total of ninety-one primary schools in the Netherlands. SUBJECTS: In total 1501 primary caregivers completed a questionnaire to measure children's fruit and vegetable consumption, home availability of fruit and vegetables, parental perceptions of the local food shopping environment (price, quality and availability), the child's socio-economic status, the child's ethnicity and maternal height and weight. RESULTS: The home availability of fruit and vegetables was positively associated with children's fruit and vegetable intake (P,0?01 and P,0?001, respectively). Negative parental perceptions of the local food shopping environment were associated with less fruit available at home (P,0?05, P,0?01 and P,0?05 for price, quality and availability of fruit, respectively). No significant associations were found between parental perception of the local food shopping environment and children's fruit and vegetable consumption. We found no evidence that home availability of fruit and vegetables mediates the association between parental perception of the local food environment and children's fruit and vegetable intake. CONCLUSIONS: Interventions focusing on improving the home availability of fruit and vegetables may help to increase children's fruit and vegetable consumption. However, more data are required on factors influencing the home availability of fruit and vegetables.

How healthcare professionals respond to parents with religious objections to vaccination: a qualitative study.

BACKGROUND: In recent years healthcare professionals have faced increasing concerns about the value of childhood vaccination and many find it difficult to deal with parents who object to vaccination. In general, healthcare professionals are advised to listen respectfully to the objections of parents, provide honest information, and attempt to correct any misperceptions regarding vaccination. Religious objections are one of the possible reasons for refusing vaccination. Although religious objections have a long history, little is known about the way healthcare professionals deal with these specific objections. The aim of this study is to gain insight into the responding of healthcare professionals to parents with religious objections to the vaccination of their children. METHODS: A qualitative interview study was conducted with health care professionals (HCPs) in the Netherlands who had ample experience with religious objections to vaccination. Purposeful sampling was applied in order to include HCPs with different professional and religious backgrounds. Data saturation was reached after 22 interviews, with 7 child health clinic doctors, 5 child health clinic nurses and 10 general practitioners. The interviews were thematically analyzed. Two analysts coded, reviewed, discussed, and refined the coding of the transcripts until consensus was reached. Emerging concepts were assessed using the constant comparative method from grounded theory. RESULTS: Three manners of responding to religious objections to vaccination were identified: providing medical information, discussion of the decision-making process, and adoption of an authoritarian stance. All of the HCPs provided the parents with medical information. In addition, some HCPs discussed the decision-making process. They verified how the decision was made and if possible consequences were realized. Sometimes they also discussed religious considerations. Whether the decision-making process was discussed depended on the willingness of the parents to engage in such a discussion and on the religious background, attitudes, and communication skills of the HCPs. Only in cases of tetanus post-exposure-prophylaxis, general practitioners reported adoption of an authoritarian stance. CONCLUSION: Given that the provision of medical information is generally not decisive for parents with religious objections to vaccination, we recommend HCPs to discuss the vaccination decision-making process, rather than to provide them with extra medical information.

How orthodox protestant parents decide on the vaccination of their children: a qualitative study.

BACKGROUND: Despite high vaccination coverage, there have recently been epidemics of vaccine preventable diseases in the Netherlands, largely confined to an orthodox protestant minority with religious objections to vaccination. The orthodox protestant minority consists of various denominations with either low, intermediate or high vaccination coverage. All orthodox protestant denominations leave the final decision to vaccinate or not up to their individual members. METHODS: To gain insight into how orthodox protestant parents decide on vaccination, what arguments they use, and the consequences of their decisions, we conducted an in-depth interview study of both vaccinating and non-vaccinating orthodox protestant parents selected via purposeful sampling. The interviews were thematically coded by two analysts using the software program Atlas.ti. The initial coding results were reviewed, discussed, and refined by the analysts until consensus was reached. Emerging concepts were assessed for consistency using the constant comparative method from grounded theory. RESULTS: After 27 interviews, data saturation was reached. Based on characteristics of the decision-making process (tradition vs. deliberation) and outcome (vaccinate or not), 4 subgroups of parents could be distinguished: traditionally non-vaccinating parents, deliberately non-vaccinating parents, deliberately vaccinating parents, and traditionally vaccinating parents. Except for the traditionally vaccinating parents, all used predominantly religious arguments to justify their vaccination decisions. Also with the exception of the traditionally vaccinating parents, all reported facing fears that they had made the wrong decision. This fear was most tangible among the deliberately vaccinating parents who thought they might be punished immediately by God for vaccinating their children and interpreted any side effects as a sign to stop vaccinating. CONCLUSIONS: Policy makers and health care professionals should stimulate orthodox protestant parents to make a deliberate vaccination choice but also realize that a deliberate choice does not necessarily mean a choice to vaccinate.

[Strategies to prevent the transmission of multidrug-resistant pathogens and their practical implementation in oupatient care]. / Präventionsstrategien zur Vermeidung der Übertragung multiresistenter Erreger und praktische Umsetzung in der ambulanten Pflege.

BACKGROUND: Multidrugresistant pathogens which are highly relevant for infection control in hospitals and other health-care facilities are a serious public health problem and a big challenge for all players in the health sector. In order to prevent the spread of multi-resistant pathogens the Commission for Hospital Hygiene of the Robert Koch-Institute (RKI) has published guidelines. These recommendations refer to the consequent implementation of an infection control management in all health care settings, including outpatient care. In Germany there are only few data available concerning infection control management and the implementation of preventive strategies in outpatient care. SUBJECT: To what extent are national guidelines concerning infection control of multidrugresistant pathogens (i.e. methicillin-resistant Staphylococcus aureus, MRSA) feasible and practicable in outpatient care? And what are the reasons not to practice these strategies. METHOD: In outpatient care the status of the infection control management and the implementation of prevention strategies was surveyed and assessed. Data were collected by structured interviews - a face to face method. RESULT: Guidelines concerning infection control management are not always sufficiently implemented in outpatient care. There are multiple reasons for this, such as, e.g., lack of compliance with the recommendations as well as structural problems in the health-care system, and special challenges of outpatient care. CONCLUSION: Implementation of an infection control management concerning multidrug-resistant pathogens in outpatient care is problematic. Prevention strategies are commonly not known or not adequately implemented into daily practice. Actions to improve the situation should focus at the individual level (e.g., trainings in the context of the initiative "clean hands" ), the institutional level (improving networking, bonus schemes) and the social level (financial and legal support for outpatient care centres to bear the expenses of infection control management, "search and destroy").

Pioglitazone, etoricoxib, interferon-α, and metronomic capecitabine for metastatic renal cell carcinoma: final results of a prospective phase II trial.

We enrolled 45 patients with metastatic renal cell carcinoma (RCC) at a progressive disease between March 2003 and April 2008 to assess the impact of an anti-inflammatory treatment regime in combination with metronomic low-dose chemotherapy. 42% of the patients had been systemically pre-treated. Therapy consisted of etoricoxib 60 mg daily plus pioglitazone 60 mg daily, day 1+, low-dose interferon-α 4.5 MU sc three times a week, week 1+ and low-dose capecitabine 1 g/m(2) twice daily orally for 14 days, every 3 weeks, day 1+, until disease progression. Objective response was observed in 35% of the patients (PR 27, CR 9%), which was paralleled by strong CRP decline for all patients with initially elevated CRP levels (n = 32). CRP values decreased from mean 42.3 mg/L (range 9.1-236), to 11.1 mg/L, (range 1.1-35.6), P = 0.006. Median overall survival and progression-free survival for the total cohort were 26.9 and 7.2 months for patients with elevated CRP 24.4 and 11.3 months (95% CI, 22.8-31.0/5.7-16.9) and 13.8-2.6 months (95% CI, 6.5-21.1/0.4-4.8) for the non-elevated CRP group, respectively (P = 0.082/0.017). Median observation time: 26.1 months; Overall survival at 5 years: 18%. Toxicity>WHO grade 3 was reported: Hand-foot syndrome in 16 patients (36%), diarrhea in 4, and pneumonia in 2 patients. Our data allow us to conclude that the control of tumor-associated inflammation is an important therapeutic principle in patients with metastatic RCC.

Measuring vaccination coverage in a hard to reach minority.

BACKGROUND: Although childhood vaccination programmes have been very successful, there are some hard to reach minority groups that object to vaccination. The Netherlands has experienced several epidemics of vaccine-preventable diseases, confined to the orthodox Protestant minority. However, vaccination coverage in this minority is still unknown and this hampers prevention and control of epidemics. METHODS: We estimated vaccination coverage among the orthodox Protestant minority and its various subgroups (denominations), using two sub-studies with different design and study population. For both sub-studies separately, we determined overall vaccination coverage and vaccination coverage per denomination. The results were compared and discussed. RESULTS: An online survey was filled out by 1778 orthodox Protestant youngsters, invited via orthodox Protestant media using a snowball method. Next to that, results of a national sample study on vaccination were used, of which only orthodox Protestant respondents were included in our analyses (N = 2129). Overall vaccination coverage among orthodox Protestants in The Netherlands was estimated to be at minimum 60%. Moreover, in both sub-studies three clusters of denominations could be identified, with high (>85%), intermediate (50-75%) and low (<25%) vaccination coverage. CONCLUSION: The integration of both sub-studies, with their own specific strengths and weaknesses, added to our insight in the vaccination coverage in this minority. Based on these results, we recommend to focus prevention and control of vaccine-preventable diseases on the orthodox Protestant subgroups with intermediate and low vaccination coverage.

Soluble immune receptor serum levels are associated with age, but not with clinical phenotype or disease severity in childhood atopic dermatitis.

BACKGROUND: Soluble immune receptors (SIRs) have been proposed as biomarkers in patients with atopic dermatitis (AD). However, their clinical applicability in affected children has rarely been studied. OBJECTIVE: To assess the diagnostic usefulness of serum SIRs in childhood AD by correlating the obtained receptor profiles with serological parameters and clinical features such as age, AD phenotype and disease severity. METHODS: We investigated 100 children with AD. The sCD14, sCD23, sCD25, sCD30, total IgE (tIgE) and eosinophilic cationic protein (ECP) were determined using sera of all children. The clinical phenotype was classified as extrinsic AD (ADe) or intrinsic AD (ADi) by the presence of allergen-specific IgE antibodies. RESULTS: A total of 55 male and 45 female children were recruited. The sCD23, sCD25 and sCD30 serum levels revealed significant age-dependency. At a mean SCORAD of 40 (range 8-98), none of the evaluated SIRs was correlated to disease severity. In all, 73% of patients suffered from ADe while 27% showed the ADi phenotype. None of the analysed SIRs differed significantly between ADe and ADi patients, while tIgE and ECP levels were elevated in the ADe subgroup. CONCLUSION: The current study provides evidence that sCD23, sCD25 and sCD30 serum levels are highly age-dependent. Serum concentrations of all investigated SIRs did not significantly correlate with disease severity in children with AD and were not differentially expressed in patients of different AD phenotypes. Therefore, we believe that the studied SIRs cannot be regarded as clinically useful biomarkers for the assessment of childhood AD.
