Abstract
BACKGROUND Electronic clinical decision-making support systems (eCDSS) aim to assist clinicians making complex patient management decisions and improve adherence to evidence-based guidelines. Integrated management of Childhood Illness (IMCI) provides guidelines for management of sick children attending primary health care clinics and is widely implemented globally. An electronic version of IMCI (eIMCI) was developed in South Africa. METHODS We conducted a cluster randomized controlled trial comparing management of sick children with eIMCI to the management when using paper-based IMCI (pIMCI) in one district in KwaZulu-Natal. From 31 clinics in the district, 15 were randomly assigned to intervention (eIMCI) or control (pIMCI) groups. Computers were deployed in eIMCI clinics, and one IMCI trained nurse was randomly selected to participate from each clinic. eIMCI participants received a one-day computer training, and all participants received a similar three-day IMCI update and two mentoring visits. A quantitative survey was conducted among mothers and sick children attending participating clinics to assess the quality of care provided by IMCI practitioners. Sick child assessments by participants in eIMCI and pIMCI groups were compared to assessment by an IMCI expert. RESULTS Self-reported computer skills were poor among all nurse participants. IMCI knowledge was similar in both groups. Among 291 enrolled children: 152 were in the eIMCI group; 139 in the pIMCI group. The mean number of enrolled children was 9.7 per clinic (range 7-12). IMCI implementation was sub-optimal in both eIMCI and pIMCI groups. eIMCI consultations took longer than pIMCI consultations (median duration 28 minutes vs 25 minutes; p = 0.02). eIMCI participants were less likely than pIMCI participants to correctly classify children for presenting symptoms, but were more likely to correctly classify for screening conditions, particularly malnutrition. eIMCI participants were less likely to provide all required medications (124/152; 81.6% vs 126/139; 91.6%, p= 0.026), and more likely to prescribe unnecessary medication (48/152; 31.6% vs 20/139; 14.4%, p = 0.004) compared to pIMCI participants. CONCLUSIONS Implementation of eIMCI failed to improve management of sick children, with poor IMCI implementation in both groups. Further research is needed to understand barriers to comprehensive implementation of both pIMCI and eIMCI. (349) CLINICAL TRIALS REGISTRATION: Clinicaltrials.gov ID: BFC157/19, August 2019.

Abstract
Abstract
Background
The neutrophil-lymphocyte ratio (NLR), derived from the complete blood count, independently predicts atherosclerotic events and is a potential biomarker for residual inflammatory risk. A previous study showed that interleukin (IL)-1β inhibition reduces the NLR, but whether inhibition with IL-6, a cytokine downstream of IL-1, also lowers the NLR is unknown.
Purpose
To evaluate whether ziltivekimab, a monoclonal antibody targeting the IL-6 ligand, dose-dependently lowers the NLR compared to placebo.
Methods
The phase II RESCUE trial randomized 264 patients with moderate to severe chronic kidney disease (CKD) and high-sensitivity CRP (hsCRP) >2mg/L in a 1:1:1:1 ratio to placebo or ziltivekimab 7.5 mg, 15 mg, and 30 mg subcutaneously once every four weeks. As previously reported, the trial met its primary endpoint as demonstrated by hsCRP reductions of 4% in the placebo group as compared to 77%, 88%, and 92% at 12 weeks in the ziltivekimab 7.5, 15, and 30 mg groups, respectively. Using RESCUE trial data, we further evaluated the percent change from baseline in the NLR at 12 weeks and sought evidence of correlation between any observed changes in the NLR with changes in other measured biomarkers.
Results
Ziltivekimab dose-dependently reduced the NLR starting at week one and sustained through week 12 (Table). The median change in the NLR at 12 weeks, the primary pre-specified endpoint, was −13.5% in the 7.5 mg group, −14.3% in the 15 mg group, and −22.4% in the 30 mg group compared to 1.56% in the placebo group. The estimated treatment difference was −14.6% (p=0.004), −15.3% (p=0.004), and −23.6% (p<0.0001) in the ziltivekimab 7.5, 15, and 30 mg groups respectively. These changes were driven largely by reductions in the absolute neutrophil count with minimal change in lymphocyte count. The change in NLR with ziltivekimab correlated modestly with the changes in hsCRP (R=0.26, p=0.0006), fibrinogen (R=0.18, p=0.02), and haptoglobin (R=0.17, p=0.03), but not serum amyloid A, ApoA1, ApoB, ApoB/ApoA ratio, or traditional risk markers.
Conclusions
IL-6 inhibition with ziltivekimab lowers the NLR. The ongoing ZEUS cardiovascular (CV) outcomes trial will assess whether ziltivekimab can reduce CV event rates among individuals with stage 3 to 4 CKD, known atherosclerotic disease, and elevated hsCRP. If ziltivekimab reduces CV risk, it would provide further evidence for critical inter-relationships between bone marrow function and atherothrombosis.

Abstract
Abstract
Introduction
In the US phase 2 RESCUE trial, ziltivekimab, a fully human monoclonal antibody against the ligand of the pro-inflammatory cytokine interleukin-6, was shown to reduce biomarkers of inflammation in patients with chronic kidney disease (CKD) and elevated levels of high-sensitivity C-reactive protein (hsCRP), a marker of inflammation and cardiac risk.1 Here, we present outcomes from the phase 2 RESCUE-2 trial of ziltivekimab in a patient population from Japan.
Purpose
To evaluate the efficacy and safety of ziltivekimab 15 mg and 30 mg compared with placebo in Japanese patients with non-dialysis-dependent CKD (NDD-CKD).
Methods
We conducted a randomized, double-blind, placebo-controlled trial in 36 patients aged ≥20 years with stage 3–5 NDD-CKD and hsCRP ≥2 mg/L. Patients were randomly assigned to receive subcutaneous ziltivekimab 15 mg (n=11) or 30 mg (n=12), or placebo (n=13) at weeks 0, 4 and 8. The primary endpoint was percentage change in hsCRP levels from baseline to end of treatment (EOT) (average of week 10 and week 12 values); secondary endpoints included percentage change from baseline to EOT in levels of fibrinogen, serum amyloid A (SAA), N-terminal pro B-type natriuretic peptide (NT-proBNP) and lipids. Analysis of endpoints was performed using Wilcoxon two-sample test; differences between treatment groups were calculated using the Hodges–Lehmann estimator.
Results
Baseline characteristics are shown in the Table. At EOT, median hsCRP levels were reduced by 96% and 93% in the ziltivekimab 15 mg and 30 mg groups, respectively, compared with 27% for placebo (both p<0.001 vs placebo). At both doses, ziltivekimab provided rapid and sustained suppression of hsCRP over the 12-week treatment period (Figure). Statistically significant reductions in levels of the inflammatory markers SAA (15 mg: 71%; 30 mg: 58%; placebo: 30%; both p<0.01 vs placebo) and fibrinogen (38%; 34%; 2%; both p<0.0001 vs placebo) were also observed. Ziltivekimab was well tolerated, did not result in persistent neutropenia or thrombocytopenia, and had minimal effect on liver enzyme levels. There was a non-significant increase in low-density lipoprotein levels and a neutral effect on high-density lipoprotein levels. There was a limited, but statistically significant (p<0.05 vs placebo) increase in triglycerides, whereby levels increased in some patients and decreased in others.
Conclusion
Ziltivekimab effectively reduced inflammatory biomarkers associated with atherosclerosis in patients from Japan with CKD and residual inflammatory risk as measured by hsCRP. A significant reduction of more than 90% in hsCRP levels for both doses of ziltivekimab was demonstrated, with a safety profile similar to placebo. Overall, the results of the RESCUE-2 trial in Japan are consistent with the efficacy and safety results of the US-based RESCUE trial.

Abstract
BACKGROUND Major causes of under-5 child deaths in South Africa (SA) are well recognised, and child mortality rates are falling. The focus of child health is therefore shifting from survival to disease prevention and thriving, but local data on the non-fatal disease burden are limited. Furthermore, COVID-19 has affected children's health and wellbeing, both directly and indirectly. OBJECTIVES To describe the pattern of disease on admission of children at different levels of care, and assess whether this has been affected by COVID-19. METHODS Retrospective reviews of children's admission and discharge registers were conducted for all general hospitals in iLembe and uMgungundlovu districts in KwaZulu-Natal Province, SA, from January 2018 to September 2020. The Global Burden of Disease framework was adapted to create a data capture sheet with four broad diagnostic categories and 37 specific cause categories. Monthly admission numbers were recorded per cause category, and basic descriptive analysis was completed in Microsoft Excel. RESULTS Overall, 36 288 admissions were recorded across 18 hospital wards, 32.0% at district, 49.8% at regional and 18.2% at tertiary level. Communicable diseases, perinatal conditions and nutritional deficiencies (CPNs) accounted for 37.4% of admissions, non-communicable diseases (NCDs) for 43.5% and injuries for 17.1%. The distribution of broad diagnostic categories varied across levels of care, with CPNs being more common at district level and NCDs more common at regional and tertiary levels. Unintentional injuries represented the most common cause category (16.6%), ahead of lower respiratory tract infections (16.1%), neurological conditions (13.6%) and diarrhoeal disease (8.4%). The start of the local COVID-19 outbreak coincided with a 43.1% decline in the mean number of monthly admissions. Admissions due to neonatal conditions and intentional injuries remained constant during the COVID-19 outbreak, while those due to other disease groups (particularly respiratory infections) declined. CONCLUSIONS Our study confirms previous concerns around a high burden of childhood injuries in our context. Continued efforts are needed to prevent and treat traditional neonatal and childhood illnesses. Concurrently, the management of NCDs should be prioritised, and evidence-based strategies are sorely needed to address the high injury burden in SA.

Abstract
OBJECTIVES There is a need for precision medicine and an unspoken promise of an optimal approach for identification of the right patients for value-based medicine based on big data. However, there may be a misconception that measurement of proteins is more valuable than measurement of fewer selected biomarkers. In population-based research, variation may be somewhat eliminated by quantity. However, this fascination of numbers may limit the attention to and understanding of the single. This review highlights that protein measurements (with collagens as examples) may mean different things depending on the targeted epitope - formation or degradation of tissues, and even signaling potential of proteins. DESIGN AND METHODS PubMed was searched for collagen, neo-epitope, biomarkers. RESULTS Ample examples of assays with specific epitopes, either pathological such as HbA1c, or domain specific such as pro-peptides, which total protein arrays would not have identified were evident. CONCLUSIONS We suggest that big data may be considered as the funnel of data points, in which most important parameters will be selected. If the technical precision is low or the biological accuracy is limited, and we include suboptimal quality of biomarkers, disguised as big data, we may not be able to fulfill the promise of helping patients searching for the optimal treatment. Alternatively, if the technical precision of the total protein quantification is high, but we miss the functional domains with the most considerable biological meaning, we miss the most important and valuable information of a given protein. This review highlights that measurements of the same protein in different ways may provide completely different meanings. We need to understand the pathological importance of each epitope quantified to maximize protein measurements.

Abstract
BACKGROUND The Self-reported Foot and Ankle Score (SEFAS) is a patient-reported outcome measure used to evaluate foot and ankle disorders. The purpose of this study was to translate, cross-culturally adapt and validate the Danish language version of the SEFAS in patients with ankle-related fractures. METHODS Forward-backward translation, cross-cultural adaption and validation were performed. In total, 125 patients completed the SEFAS-DK and the Danish version of American Orthopaedic Foot and Ankle Score (AOFAS-DK) at three time points after the date of fracture. The evaluation was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. RESULTS The intra-class correlation coefficient (ICC) level of the SEFAS-DK total score was 0.93 (95% confidence interval [CI]: 0.88-0.96). Cronbach's alpha (CA) for the SEFAS-DK was 0.93, while the floor and ceiling effect at week 6 post-injury was 22.4%. Construct validity was correlated with the AOFAS, and >75% of the pre-defined hypotheses could be confirmed. Responsiveness was analysed using longitudinal data. The minimal clinical important change (MCIC) showed that the SEFAS-DK detects changes in physical function over time. CONCLUSION The Danish version of the SEFAS showed overall good reliability, validity and responsiveness. SEFAS-DK can be used to evaluate physical function in patients with ankle-related fractures.

Abstract
BACKGROUND Current evidence indicates that children are relatively spared from direct COVID-19-related morbidity and mortality, but that the indirect effects of the pandemic pose significant risks to their health and wellbeing. OBJECTIVES To assess the impact of the local COVID-19 outbreak on routine child health services. METHODS The District Health Information System data set for KwaZulu-Natal (KZN) provincial health services was accessed, and monthly child health-related data were extracted for the period January 2018 - June 2020. Chronological and geographical variations in sentinel indicators for service access, service delivery and the wellbeing of children were assessed. RESULTS During April - June 2020, following the start of the COVID-19 outbreak in KZN, significant declines were seen for clinic attendance (36%; p=0.001) and hospital admissions (50%; p=0.005) of children aged <5 years, with a modest recovery in clinic attendance only. Among service delivery indicators, immunisation coverage recovered most rapidly, with vitamin A supplementation, deworming and food supplementation remaining low. Changes were less pronounced for in- and out-of-hospital births and uptake rates of infant polymerase chain reaction testing for HIV at birth, albeit with wide interdistrict variations, indicating inequalities in access to and provision of maternal and neonatal care. A temporary 47% increase in neonatal facility deaths was reported in May 2020 that could potentially be attributed to COVID-19-related disruption and diversion of health resources. CONCLUSIONS Multiple indicators demonstrated disruption in service access, service delivery and child wellbeing. Further studies are needed to establish the intermediate- and long-term impact of the COVID-19 outbreak on child health, as well as strategies to mitigate these.

Abstract
INTRODUCTION Acetabular retroversion is assessed using pelvic X-ray. Cross-over-sign (COS), posterior-wall-sign (PWS) and ischial-spine-sign (ISS) are important radiographic signs of the condition. The pelvic area is sensitive to radiation and thus, possibilities to reduce dose should be considered. The purpose was to compare radiographic signs of acetabular retroversion on conventional pelvic anteroposterior (AP) X-rays with a low-dose slot-scanning system (EOS) in a sample of patients with retroversion of the acetabulum and to compare the radiation doses. METHODS 34 participants with radiographic signs of acetabular retroversion in one or both hips on conventional pelvic X-ray were consecutively recruited. Pelvic EOS-images were acquired in each patient and COS, PWS, ISS, COS-ratio and PWS-ratio was assessed. Radiation dose comparison of X-ray vs. EOS was performed using Dose-Area Products. RESULTS Retroversion was present in 57 out of 68 hips. The absolute agreement was 91%, 84% and 76% for COS, PWS and ISS, respectively. No statistically significant differences were present between COS-ratio and PWS-ratio in either modality and Bland-Altman limits of agreement were narrow. The mean radiation dose was 1053 mGy*cm2 in X-ray and 593 mGy*cm2 in EOS (p = 0.003). CONCLUSION The results indicate that pelvic EOS provides diagnostic qualities similar to conventional X-ray using 44% less radiation when radiographic signs of acetabular retroversion are assessed.

Abstract
PURPOSE To conduct a systematic review and meta-analysis comparing physical function and complications following DIATF surgery with external fixation (EF) or open reduction internal fixation (ORIF). METHOD A search was conducted using PubMed, Embase, Cochrane CENTRAL, Open Grey and Orthopaedic Proceedings. Studies with a level of evidence of I-III on patients (≥ 18 years) with DIATFs operated on with either EF or ORIF were included. A total of 3814 studies were identified. The Cochrane Risk of Bias Tool for randomised controlled trials and the ROBINS-I tool for nonrandomised studies were used to assess risk of bias. RESULTS Nine studies with 478 patients, 271 ORIF and 197 EF met the inclusion criteria. The mean follow-up ranged from 12 to 38 months. The meta-analysis showed a higher incidence of superficial wound infections (RR = 2.94, 95% CI 1.62-5.34, p = 0.0004) and malunions (RR = 2.62, 95% CI 1.27-5.43, p = 0.009) in the EF group compared to the ORIF group. Also worse physical function was associated with the EF group. However, the overall evidence was low. CONCLUSION This systematic review is the first to report on physical function following DIATF surgery. In general, decreased physical function was reported. The meta-analysis showed lower incidence of superficial wound infection and malunion rates in the ORIF group. Heterogeneity was low. In conclusion, this review reports lower complication rates following ORIF for DIATF. The overall evidence was limited, and therefore, the authors cannot recommend ORIF to be superior to EF treatment for DIATF. More multi-centre studies with larger sample sizes are needed to assess long-term physical function and complications following DIATF surgery. LEVEL OF EVIDENCE Level 1.

Abstract
Aims Surgical site infection (SSI) is a common complication of surgery with an incidence of about 1% in the United Kingdom. Sutures can lead to the development of a SSI, as micro-organisms can colonize the suture as it is implanted. Triclosan-coated sutures, being antimicrobical, were developed to reduce the rate of SSI. Our aim was to assess whether triclosan-coated sutures cause a reduction in SSIs following arthroplasty of the hip and knee. Patients and Methods This two-arm, parallel, double-blinded study involved 2546 patients undergoing elective total hip (THA) and total knee arthroplasty (TKA) at three hospitals. A total of 1323 were quasi-randomized to a standard suture group, and 1223 being quasi-randomized to the triclosan-coated suture group. The primary endpoint was the rate of SSI at 30 days postoperatively. Results The baseline characteristics of age, gender and comorbidities were well matched in the two groups. The rates of superficial SSI were 0.8% in the control group and 0.7% in the intervention group (p = 0.651), and when deep and superficial SSIs were combined the rates were 2.5% and 1.8 (p = 0.266). The length of stay in hospital and the rates of medical complications did not differ significantly between the groups (p = 1.000). Conclusion This trial provided no evidence that the use of triclosan-coated sutures at THA and TKA leads to a reduction in the rate of SSI. Cite this article: Bone Joint J 2018;100-B:296–302.

Abstract
Background Multiple somatic symptoms are common and may cause prolonged sickness absence (SA) and unsuccessful return to work (RTW). Aims To compare three instruments and their predictive and discriminative abilities regarding RTW. Methods A longitudinal cohort study of participants recruited from two municipal job centres, with at least 8 weeks of SA. The instruments used were the Symptom Check List of somatic distress (SCL-SOM) (score 0-48 points), the Bodily Distress Syndrome Questionnaire (BDSQ) (0-120 points) and the one-item self-rated health (SRH) (1-5 points). The instruments' predictive value was explored in a time-to-event analysis. Different cut-points were analysed to find the highest number of correctly classified RTW cases, identified in a register on public transfer payments. Results The study involved 305 subjects. The adjusted relative risk regarding prediction of RTW was 0.89 [95% confidence interval (CI) 0.83-0.95], 0.89 (95% CI 0.83-0.95) and 0.78 (95% CI 0.70-0.86) per 5-, 10- and 1-point increase in the SCL-SOM, BDSQ and SRH, respectively. After mutual adjustment for the three instruments, only the prediction of RTW from SRH remained statistically significant 0.81 (95% CI 0.72-0.92). The highest sensitivity (86%) was found by SRH at the cut-point ≤5, at which 62% were correctly classified. Conclusions All three instruments predicted RTW, but only SRH remained a significant predictor after adjustment for the SCL-SOM and BDSQ. The SRH provides an efficient alternative to more time-consuming instruments such as SCL-SOM or BDSQ for estimating the chances of RTW among sickness absentees.

Abstract
Aims A fracture of the hip is the most common serious orthopaedic
injury, and surgical site infection (SSI) is one of the most significant
complications, resulting in increased mortality, prolonged hospital
stay and often the need for further surgery. Our aim was to determine
whether high dose dual antibiotic impregnated bone cement decreases the
rate of infection. Patients and Methods A quasi-randomised study of 848 patients with an intracapsular
fracture of the hip was conducted in one large teaching hospital
on two sites. All were treated with a hemiarthroplasty. A total
of 448 patients received low dose single-antibiotic impregnated
cement (control group) and 400 patients received high dose dual-antibiotic impregnated
cement (intervention group). The primary outcome measure was deep
SSI at one year after surgery. Results The rate of deep SSI was 3.5% in the control group and 1.1% in
the intervention group
(p = 0.041; logistic regression adjusting for age and gender). The
overall rate of non-infective surgical complications did not differ
between the two groups (unadjusted chi-squared test; p > 0.999). Conclusion The use of high dose dual-antibiotic impregnated cement in these
patients significantly reduces the rate of SSI compared with standard
low dose single antibiotic loaded bone cement. Cite this article: Bone Joint J 2016;98-B:1534–1541.

Abstract
The Canadian Immunization Guide (CIG) is a trusted, reader-friendly summary of information and advice on immunization that has been used by health care providers and policy makers for decades. It is continuously updated based on new recommendations from the National Advisory Committee on Immunization (NACI) and the Committee to Advise on Tropical Medicine and Travel (CATMAT), two external advisory bodies to the Public Health Agency of Canada. In September 2016, the CIG moved to a new web platform that has improved navigability and is more mobile friendly. Between April 2015 and October 2016, five new NACI statements were published and are reflected in the CIG. The objective of this article is to provide readers with highlights of recent key changes to active vaccine recommendations in the CIG. For example, for Hepatitis (HA) vaccine, it may now be administered to persons six months of age and older and considered for all individuals receiving repeated replacement of plasma-derived clotting factors. There are now new recommendations for the use of HA immunoglobulin post-exposure prophylaxis. For Human papillomavirus (HPV) vaccine, any of the authorized HPV vaccines in Canada, including HPV9 vaccine, can be used according to the recommended HPV immunization schedules. For influenza vaccine, adults with neurologic or neurodevelopment conditions have been added to the group for whom influenza vaccination is particularly recommended, high-dose influenza vaccine has been approved for use in Canada in adults ≥65 years of age and live attenuated influenza vaccine (LAIV) is no longer a preferentially recommended product for use in children and adolescents. On an individual basis, pneumococcal conjugate 13-valent (PNEU-C-13) vaccine may be recommended to immunocompetent adults aged 65 years and older if not previously immunized against pneumococcal disease. When it is given, it should precede the pneumococcal polysaccharide 23-valent (PNEU-P-23) vaccine. Varicella immune globulin may now be administered up to 10 days since last exposure for the purpose of disease attenuation and there were a number of minor changes to the criteria for assessing varicella immunity.

Abstract
A new fiber-based modulated optical reflectance configuration is developed in this work. The technique maintains the fiber-based heating laser (pump) and detection laser (probe) in close proximity at a fixed separation distance in a ceramic ferrule. The pump beam periodically heats the sample inducing thermal waves into the sample. The probe beam measures the temperature response at a known distance from the pump beam over a range of heating modulation frequencies. The thermal diffusivity of the sample may be calculated from the phase response between the input heat flux and the temperature response of a sample having a reflective surface. The unique measurement configuration is ideal for in situ measurements and has many advantages for laboratory-based systems. The design and development of the system are reported along with theoretical justification for the experimental design. The thermal diffusivities of Ge and SiC are measured and found to be within 10% of reported literature values. The diffusivity for SiO2 is measured with a relative difference of approximately 100% from the literature value when the ferrule is in contact with the sample. An additional measurement was made on the SiO2 sample with the ferrule not in contact resulting in a difference of less than 2% from the literature value. The difference in the SiO2 measurement when the ferrule is in contact with the sample is likely due to a parallel heat transfer path through the dual-fiber ferrule assembly.

Abstract
Maximal muscle strength during shoulder elevation, arm abduction and handgrip was compared for workers performing repetitive work and more varied work. No difference was found except for shoulder elevation strength of male workers. Furthermore, preliminary analyses on workers performing repetitive work for at least 8 years indicated that the muscle strength of male workers with musculoskeletal symptoms, but not of females, was considerably lower than for asymptomatic workers.

Abstract
Consecutive chest radiographs (n = 2 303) in 601 patients in the intensive care units (ICU) were analyzed with regard to main disease and indication. Two thirds of the patients were transferred for routine post-operative treatment, 14 per cent mainly for cardiopulmonary insufficiency. The remainder were referred because of various clinical conditions. The main indications for chest radiography were routine radiographic follow-up and/or control of the position of catheters, tubes, drainages etc. (50%). Obvious clinical indications appeared in only about 1/4 of the patients. When the patients were discharged from the ICU all chest radiographs were analyzed with regard to their predicted future value. Films considered not worth storing were removed and stored in a separate archive (57%). During a 15-month follow-up period none of the removed films were requested, indicating that a substantial number of films can be sorted out continuously. The possibility to reduce and to ‘clinically compress’ the amount of data in a future digital picture archive is emphasized.

Abstract
In order to analyze whether ultrasonography with a reasonable degree of confidence can replace radiography in the diagnosis of sinusitis, 138 patients with clinical signs of sinusitis were examined with both methods. It was found that maxillary sinus fluid was recognized ultrasonographically with a confidence that increased with the amount of fluid, judged from radiographic examinations. In a sub-group of 45 cases, fluid confirmed by maxillary sinus puncture was detected by ultrasonography in 35/45 sinuses (78%) and by radiology in 38/45 sinuses (84%). In patients with radiographically normal maxillary sinuses, the correlation to ultrasound was good. However, mucosal swelling and polyps or cysts observed at radiography were poorly demonstrated by ultrasonography. In addition, the ultrasound method was not reliable for frontal sinus diagnosis. It was concluded that ultrasonography can be recommended in maxillary sinusitis for follow-up of treatment and as a screening method before sinus radiography.

Abstract
In a double-blind study 238 patients were examined with lumbar myelography using iotrolan or iohexol in randomized sequence in order to evaluate the image quality, the safety and tolerance of iotrolan by monitoring the adverse effects with special attention to late reactions. There were no serious complications. On the first day 28 patients (24%) had headache after iotrolan and 41 (34%) after iohexol. This difference was not significant, and these frequencies are similiar to those found after spinal puncture alone. The second most frequent side effect was neck pain; the duration of neck pain were significantly longer after myelography with iohexol than with iotrolan. There was a significantly higher frequency of adverse effects in females the first 24 hours, but during examination and on days 2 to 4 there were no differences between males and females. Anamnestic information or myelographic diagnosis could not predict which patients would have side effects. The image quality was excellent or good in all examinations but one. It is concluded that iotrolan is a safe contrast medium well suited for lumbar myelography.

Abstract
We report results from the first search for ν_{μ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

Abstract
X-linked intellectual disability (XLID) is a clinically and genetically heterogeneous disorder. During the past two decades in excess of 100 X-chromosome ID genes have been identified. Yet, a large number of families mapping to the X-chromosome remained unresolved suggesting that more XLID genes or loci are yet to be identified. Here, we have investigated 405 unresolved families with XLID. We employed massively parallel sequencing of all X-chromosome exons in the index males. The majority of these males were previously tested negative for copy number variations and for mutations in a subset of known XLID genes by Sanger sequencing. In total, 745 X-chromosomal genes were screened. After stringent filtering, a total of 1297 non-recurrent exonic variants remained for prioritization. Co-segregation analysis of potential clinically relevant changes revealed that 80 families (20%) carried pathogenic variants in established XLID genes. In 19 families, we detected likely causative protein truncating and missense variants in 7 novel and validated XLID genes (CLCN4, CNKSR2, FRMPD4, KLHL15, LAS1L, RLIM and USP27X) and potentially deleterious variants in 2 novel candidate XLID genes (CDK16 and TAF1). We show that the CLCN4 and CNKSR2 variants impair protein functions as indicated by electrophysiological studies and altered differentiation of cultured primary neurons from Clcn4(-/-) mice or after mRNA knock-down. The newly identified and candidate XLID proteins belong to pathways and networks with established roles in cognitive function and intellectual disability in particular. We suggest that systematic sequencing of all X-chromosomal genes in a cohort of patients with genetic evidence for X-chromosome locus involvement may resolve up to 58% of Fragile X-negative cases.

Abstract
BACKGROUND A prediction model including age, self-rated health (SRH) and prior sickness absence (SA) has previously been found to predict frequent SA. AIMS To further validate the model and develop it for clinical use. METHODS A multicentre study of care of the elderly workers employed at one of 14 centres in Aarhus (Denmark). SA episodes recorded in the year prior to baseline and both age and SRH at baseline were included in a prediction model for frequent (three or more) SA episodes during a 1-year follow-up period. The prediction model was developed in the largest centre. Risk predictions and discrimination between high- and low-risk workers were investigated in the other centres. The prediction rule 'SRH-prior SA' was derived from the prediction model and prognostic properties of the prediction rule were investigated for each centre, using score <0 as cut-off. RESULTS Of 2562 workers, 1930 had complete data for analysis. Predictions were accurate in 4 of 13 centres; discrimination was good in five and fair in another five centres. Prediction rule scores <0 identified workers at risk of frequent SA with sensitivities of 0.17-0.54, specificities of 0.86-0.96 and positive predictive values of 0.54-0.87 across centres. CONCLUSIONS The prediction model discriminated between workers at high and low risk of frequent SA in the majority of centres. The prediction rule 'SRH-prior SA' can be used in clinical practice specifically to identify workers at high risk of frequent SA.

Abstract
OBJECTIVES Specifically we aim to demonstrate that the results of our earlier safety data hold true in this much larger multi-national and multi-ethnical population. BACKGROUND We sought to re-evaluate the frequency, manifestations, and severity of acute adverse reactions associated with administration of several gadolinium- based contrast agents during routine CMR on a European level. METHODS Multi-centre, multi-national, and multi-ethnical registry with consecutive enrolment of patients in 57 European centres. RESULTS During the current observation 37,788 doses of Gadolinium based contrast agent were administered to 37,788 patients. The mean dose was 24.7 ml (range 5-80 ml), which is equivalent to 0.123 mmol/kg (range 0.01 - 0.3 mmol/kg). Forty-five acute adverse reactions due to contrast administration occurred (0.12%). Most reactions were classified as mild (43 of 45) according to the American College of Radiology definition. The most frequent complaints following contrast administration were rashes and hives (15 of 45), followed by nausea (10 of 45) and flushes (10 of 45). The event rate ranged from 0.05% (linear non-ionic agent gadodiamide) to 0.42% (linear ionic agent gadobenate dimeglumine). Interestingly, we also found different event rates between the three main indications for CMR ranging from 0.05% (risk stratification in suspected CAD) to 0.22% (viability in known CAD). CONCLUSIONS The current data indicate that the results of the earlier safety data hold true in this much larger multi-national and multi-ethnical population. Thus, the "off-label" use of Gadolinium based contrast in cardiovascular MR should be regarded as safe concerning the frequency, manifestation and severity of acute events.

Abstract
BACKGROUND The optimal type of exercise protocol in the physical rehabilitation of non-specific neck pain has not yet been established. Furthermore, the role of fear-avoidance belief in the maintenance of pain and disability has been highlighted. Research indicates that exercise may be a means to reduce fear-avoidance belief, but evidence is scarce. AIM To compare the effect of two different exercise programs on pain, strength and fear-avoidance belief. DESIGN Randomized clinical trial. SETTING A specialized outpatient hospital clinic in Denmark. POPULATION Twenty-three men and 60 women on sick leave due to non-specific neck pain. METHODS Participants were randomized to either general physical activity (GPA group) or GPA and additional strength training of the neck and shoulder (SST group). The primary outcome was pain intensity. Secondary outcomes were muscle strength of the neck and shoulder and fear-avoidance belief. RESULTS Pain was significantly reduced within groups with a median of -1 (IQR: -3 to 0, P<0.001) in the SST group and -1 (IQR: -4 to 1, P=0.046) in the GPA group. The difference between groups was not significant. Changes in strength did not differ between groups. Both groups experienced significant increases in neck flexion strength of 14.7 N (IQR: -1 to 28.4, P=0. 001) in the SST group and 6.9 N (IQR: -4.9 to18.6, P=0.014) in the GPA group. Furthermore, the SST group achieved an increase of 18.6 N (IQR: -2.6 to 69.7, P=0.005) in neck extension. Fear-avoidance beliefs improved with 6 (IQR: 3 to 12, P<0.001) in the SST group, while the GPA group improved with 3 (IQR: 0 to 8, P=0.004). This between-group difference was significant (P=0.046). CONCLUSION AND REHABILITATION IMPACT This study indicates that in rehabilitation of subjects severely disabled by non-specific neck pain, there is no additional improvement on pain or muscle strength when neck exercises are given as a home-based program with a minimum of supervision. However, strength training of the painful muscles seems to be effective in decreasing fear-avoidance beliefs.

Abstract
BACKGROUND Full recovery in muscle strength and functional performance may not be achieved after ACL-injury. AIM The aim of this study is to investigate loading patterns during jumping, muscle function and functional performance in ACL-reconstructed patients and to investigate the origin of between-limb asymmetry by means of a 3-dimensional movement analysis. Design is cross-sectional. METHODS 23 ACL-reconstructed men (27.2±7.5 years, BMI: 25.4±3.2) 27±7 month post-surgery and 25 matched controls (27.2±5.4 years, BMI: 24.1±1.8) were included. Participants performed (i) bilateral and (ii) unilateral counter movement jumps (CMJ). A 3-D movement analysis was performed by a six-camera Vicon MX-system. Subsequently, jump height (JH), knee joint range of motion (ROM), peak and mean sagittal knee moments were analyzed (iii) one-leg maximal jump for distance was performed, and (iv) maximal unilateral isometric knee extensor and flexor strength (MVC) were measured using stabilized dynamometry. RESULTS No in-between group differences in age or BMI were observed. CMJ: Between-limb asymmetry ratios for ROM differed (p<0.01) between patients and controls in both types of CMJ (96.1% vs. 102.6% and 87.0% vs. 99.9% in bilateral and single-leg CMJs, respectively). Jump for distance: Patients demonstrated greater (p<0.01) asymmetry for jump length (92.9% vs. 98.6%). MVC: Asymmetry in hamstring MVC was greater (p<0.001) for patients than controls (77.4% vs. 101.3%). CONCLUSIONS ACL-patients showed reduced function of the operated leg~2 years post ACL-reconstruction, especially for hamstring MVC. Hamstrings are important protagonists to the ACL, thus representing a potential risk factor for secondary ACL-rupture and/or osteoarthritis.
