Abstract
Background To evaluate the technique of transtibial pull-out repair with tibial interference screw fixation for medial meniscus posterior root (MMPR) tear by reporting on short-term outcomes and complications. Methods All MMPR repairs performed between January 2019 and August 2021 (n = 70) were retrospectively screened regarding demographic data and surgical parameters. The patients were questioned for performed revision surgery, symptoms and complications. The Numeric Rating Scale (NRS) for pain, Lysholm Knee Score and International Knee Documentation Committee Subjective Knee Form (IKDC) questionnaires were used to evaluate clinical outcome. In cases of revision surgery for re-tear the mode of failure was intraoperatively classified (patients with re-tear were excluded from the clinical follow-up examination). The influence of demographic and treatment parameters (surgical and rehabilitation) on the incidence and mode of re-tear and clinical scores was evaluated. Results After 2.3 ± 0.7 years, 62 patients (88.6 %) were available for follow-up. There were no direct intra- or postoperative complications. No revision was performed due to symptoms related to the tibial fixation material. The mean surgery time was 33.5 ± 10.8 min. The overall re-tear rate was 17.7 % (11 patients) of whom 10 were treated surgically and one conservatively. Primary mode of failure was suture cut-out from the meniscus (70 %). The NRS, Lysholm Knee Score and subjective IKDC were obtained in 38 patients and improved from 6.8 ± 2.4, 40.1 ± 23.9 and 32.8 ± 16.3 to 2.2 ± 2.2, 80.5 ± 16.3 and 63.0 ± 13.9, respectively (all p < 0.001). No influence was observed from demographic and treatment parameters on re-tear rates or clinical Scores. Conclusions Tibial interference screw fixation is a fast and promising technique for MMPR transtibial pull-out repair. In the presented technique, utilizing non-absorbable locking sutures alongside tibial interfenrence screw fixation, the primary mode of failure was suture cut-out from the meniscus.

Abstract
OBJECTIVES The primary objective was to perform a systematic review of predictive factors for obstetric anal sphincter injury (OASI) occurrence at first vaginal delivery, with the diagnosis made by ultrasound (US-OASI). The secondary objective was to report on incidence rates of sonographic anal sphincter (AS) trauma, including trauma that was not clinically reported at childbirth, among the studies providing data for our primary objective. METHODS We conducted a systematic search of MEDLINE, EMBASE, Web of Science, CINAHL, The Cochrane Library and ClinicalTrials.gov databases. Both observational cohort studies and interventional trials were eligible for inclusion. Study eligibility was assessed independently by two authors. Random-effects meta-analyses were performed to pool effect estimates from studies reporting on similar predictive factors. Summary odds ratio (OR) or mean difference (MD) is reported with 95% CI. Heterogeneity was assessed using the I2 statistic. Methodological quality was assessed using the Quality in Prognosis Studies tool. RESULTS A total of 2805 records were screened and 21 met the inclusion criteria (16 prospective cohort studies, three retrospective cohort studies and two interventional non-randomized trials). Increasing gestational age at delivery (MD, 0.34 (95% CI, 0.04-0.64) weeks), shorter antepartum perineal body length (MD, -0.60 (95% CI, -1.09 to -0.11) cm), labor augmentation (OR, 1.81 (95% CI, 1.21-2.71)), instrumental delivery (OR, 2.13 (95% CI, 1.13-4.01)), in particular forceps extraction (OR, 3.56 (95% CI, 1.31-9.67)), shoulder dystocia (OR, 12.07 (95% CI, 1.06-137.60)), episiotomy use (OR, 1.85 (95% CI, 1.11-3.06)) and shorter episiotomy length (MD, -0.40 (95% CI, -0.75 to -0.05) cm) were associated with US-OASI. When pooling incidence rates, 26% (95% CI, 20-32%) of women who had a first vaginal delivery had US-OASI (20 studies; I2 = 88%). In studies reporting on both clinical and US-OASI rates, 20% (95% CI, 14-28%) of women had AS trauma on ultrasound that was not reported clinically at childbirth (16 studies; I2 = 90%). No differences were found in maternal age, body mass index, weight, subpubic arch angle, induction of labor, epidural analgesia, episiotomy angle, duration of first/second/active-second stages of labor, vacuum extraction, neonatal birth weight or head circumference between cases with and those without US-OASI. Antenatal perineal massage and use of an intrapartum pelvic floor muscle dilator did not affect the odds of US-OASI. Most (81%) studies were judged to be at high risk of bias in at least one domain and only four (19%) studies had an overall low risk of bias. CONCLUSION Given the ultrasound evidence of structural damage to the AS in 26% of women following a first vaginal delivery, clinicians should have a low threshold of suspicion for the condition. This systematic review identified several predictive factors for this. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Polypharmacy (intake of ≥5 drugs) is an important issue for patients with chronic diseases such as multiple sclerosis (MS). We aimed to assess the prevalence of polypharmacy with regard to the severity of anxiety/depression and to comorbidities. Therefore, 374 MS patients from two German neurological sites were examined for drug burden, comorbidities, disability level and psychopathological measures capturing depression and anxiety using the Hospital Anxiety and Depression Scale (HADS-A and HADS-D). We found that patients with a higher HADS-D score take more medication (r = 0.217, p < 0.001). Furthermore, patients with higher depression severity were more likely to show polypharmacy (p < 0.001). These differences were not significant for anxiety. (p = 0.413). Regarding the frequency of ≥1 comorbidities, there were no significant differences between patients with different HADS-A (p = 0.375) or HADS-D (p = 0.860) severity levels, whereas the concrete number of comorbidities showed a significant positive linear correlation with HADS-A (r = 0.10, p = 0.045) and HADS-D scores (r = 0.19, p < 0.001). In conclusion, symptoms of depression pose a relevant issue for MS patients and are correlated with polypharmacy and comorbidities. Anxiety is not correlated with polypharmacy but with the frequency of several comorbidity groups in MS patients.

Abstract
BACKGROUND The posterior tibial slope has been identified as an anatomic risk factor for anterior cruciate ligament insufficiency and reruptures after anterior cruciate ligament reconstruction. Anterior tibial closing wedge osteotomy for correction of sagittal plane deformities has the potential to cause an unintended change in coronal plane alignment. PURPOSE To evaluate the effects of anterior tibial closing wedge osteotomies for correction of posterior tibial slope on coronal plane alignment using an infratuberosity surgical approach and to identify predictive factors for a change in medial proximal tibial angle (MPTA). STUDY DESIGN Case series; Level of evidence, 4. METHODS This study reports on retrospectively obtained data from radiographic measurements of 38 anterior tibial closing wedge osteotomies. All patients underwent revision anterior cruciate ligament reconstruction and had undergone ≥1 previous anterior cruciate ligament reconstruction. In all patients, an infratuberosity approach was used with angular stable plate fixation. Pre- and postoperative radiographs were examined retrospectively to detect changes in the sagittal and coronal plane alignment (posterior tibial slope and MPTA). A multivariate regression analysis was used to identify predictors for a change in MPTA. RESULTS The study group consisted of 14 women and 24 men whose mean ± SD age at the index procedure was 31.6 ± 8.7 years (range, 17-51 years). Posterior tibial slope decreased significantly (by 7.2° ± 2.3°; P < .001) from 14.6° ± 2.0° preoperatively to 7.4° ± 2.1° postoperatively. MPTA decreased significantly by 1.3° ± 1.5° (P = .005) from pre- to postoperative measurement. Mean wedge height was 9.3 ± 1.1 mm. A lower preoperative MPTA (coefficient = 0.32; P = .017; 95% CI, 0.06-0.59) and larger wedge height (coefficient = 0.48; P = .029; 95% CI, 0.05-0.9) were significant predictive factors for a decrease in MPTA. CONCLUSION Anterior tibial closing wedge osteotomy for posterior tibial slope reduction resulted in a slight but significant decrease of the MPTA in the coronal plane. These changes were dependent on the preoperative MPTA and the wedge height.

Abstract
PURPOSE To assess the longitudinal variation of the ratio of umbilical and cerebral artery pulsatility index (UCR) in late preterm fetal growth restriction (FGR). MATERIALS AND METHODS A prospective European multicenter observational study included women with a singleton pregnancy, 32+ 0-36+ 6, at risk of FGR (estimated fetal weight [EFW] or abdominal circumference [AC] < 10th percentile, abnormal arterial Doppler or fall in AC from 20-week scan of > 40 percentile points). The primary outcome was a composite of abnormal condition at birth or major neonatal morbidity. UCR was categorized as normal (< 0.9) or abnormal (≥ 0.9). UCR was assessed by gestational age at measurement interval to delivery, and by individual linear regression coefficient in women with two or more measurements. RESULTS 856 women had 2770 measurements; 696 (81 %) had more than one measurement (median 3 (IQR 2-4). At inclusion, 63 (7 %) a UCR ≥ 0.9. These delivered earlier and had a lower birth weight and higher incidence of adverse outcome (30 % vs. 9 %, relative risk 3.2; 95 %CI 2.1-5.0) than women with a normal UCR at inclusion. Repeated measurements after an abnormal UCR at inclusion were abnormal again in 67 % (95 %CI 55-80), but after a normal UCR the chance of finding an abnormal UCR was 6 % (95 %CI 5-7 %). The risk of composite adverse outcome was similar using the first or subsequent UCR values. CONCLUSION An abnormal UCR is likely to be abnormal again at a later measurement, while after a normal UCR the chance of an abnormal UCR is 5-7 % when repeated weekly. Repeated measurements do not predict outcome better than the first measurement, most likely due to the most compromised fetuses being delivered after an abnormal UCR.

Abstract
PURPOSE To determine the prevalence of an "increased posterior tibial slope (PTS)" (PTS ≥ 12°) in a population with one, two or ≥ three anterior cruciate ligament (ACL) graft insufficiencies. Furthermore, to investigate whether the prevalence of an increased PTS and the absolute PTS increases with an increasing number of ACL graft insufficiencies, as well as to determine the survival time of the first ACL graft. METHODS Patients diagnosed with an ACL graft insufficiency between January 2021 and March 2022 were included. The PTS was measured using the proximal anatomical tibial axis on long lateral knee radiographs. Patients were divided into 3 groups depending on the number of ACL graft insufficiencies: group A (1 graft insufficiency), group B (2 graft insufficiencies) and group C (≥ 3 graft insufficiencies). The prevalence of increased PTS and absolute PTS between groups was compared alongside the survival of the first ACL graft between patients with or without increased PTS. RESULTS Two-hundred and six patients (147 males/59 females) met the inclusion criteria. 73 patients showed an increased PTS [prevalence 35% [95% confidence interval (CI) (29%; 42%)]. 155 patients were found in category A, 42 patients in B and 9 patients in C. The prevalence of increased PTS for group A, B and C was, 32% [95% CI (25%; 40%)], 38% [95% CI (23%; 53%)] and 78% [95% CI (51%; 100%)], respectively. The prevalence of increased PTS and mean PTS did not increase significantly between group A and B. However, both parameters increased significantly between group A and C, and group B and C (p < 0.05). The survival time of the first ACL graft in patients with or without an increased PTS was 3 (interquartile range (IQR) 5) and 6 years (IQR 9), respectively (p < 0.05). CONCLUSION There is a 35% prevalence of increased PTS in the studied ACL graft insufficient patient cohort. The survival of the first ACL graft is shorter in patients with an increased PTS. Surgeons should be aware of the high prevalence of increased PTS when consulting patients for revision ACL reconstruction as it is an important risk factor for recurrent instability.

Abstract
The complex thermal history imposed by the laser-based powder bed fusion of metals (PBF-LB/M) process is known to promote the evolution of unique microstructures. In the present study, metastable CrMnNi steels with different nickel contents and, thus, different phase stabilities are manufactured by PBF-LB/M. Results clearly reveal that an adequate choice of materials will allow to tailor mechanical properties as well as residual stress states in the as-built material to eventually redundantize any thermal post-treatment. The chemical differences lead to different phase constitutions in as-built conditions and, thus, affect microstructure evolution and elementary deformation mechanisms upon deformation, i.e., twinning and martensitic transformation. Such alloys designed for additive manufacturing (AM) highlight the possibility to tackle well-known challenges in AM such as limited damage tolerance, porosity and detrimental residual stress states without conducting any post treatments, e.g., stress relieve and hot isostatic pressing. From the perspective of robust design of AM components, indeed it seems to be a very effective approach to adapt the material to the process characteristics of AM.

Abstract
PURPOSE The purpose of this study was to prospectively evaluate the clinical and radiological results of double level osteotomy (distal femoral lateral closed wedge and proximal tibial medial open wedge) in medial osteoarthritis and varus malalignment due to bifocal deformity of femur and tibia. METHODS From 2017 to 2019 all cases of DLO in osteoarthritic varus malaligned knees with bifocal deformity (femoral and tibial deformity) were prospectively enrolled into this observational therapeutic study. Evaluation was performed preoperatively, at six, twelve, 18 and 24 months with regard to survival (not requiring arthroplasty), functional outcome [subjective International Knee Documentation Committee score (IKDC), Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome score (KOOS) and Tegner Activity Scale], pain level (numeric rating scale), subjective satisfaction (rating 1-5), radiographic parameters on a pre-and postoperative full leg x-rays (mechanical axis, mechanical proximal tibial and distal femoral angles) and complications. For statistical evaluation student's t test, Mann-Whitney U test and Wilcoxon-signed-rank test were used. RESULTS Fifty-two consecutive cases in 48 patients were enrolled in the study. Three cases were excluded, resulting in a follow-up rate of 94%. No arthroplasties were performed within follow-up. All functional outcome scores substantially and significantly increased as early as six months after the index procedure and further increased until final follow-up (p < 0.001). Pain level significantly decreased (p < 0.001). At final follow-up all patients stated that they would retrospectively undergo the operation again, and rated the result with 4.5 ± 0.6 out of 5 (3-5). Radiographic parameters were within physiological limits postoperatively. No severe complications occurred. CONCLUSIONS Double level osteotomy has excellent short-term results while maintaining physiological radiographic parameters. Therefore, it should be an integral part and standard procedure in realignment surgery for monocompartimental osteoarthritis. LEVEL OF EVIDENCE IV (prospective observational therapeutic study).

Abstract
OBJECTIVE To examine the association of umbilical venous diameter and flow in monochorionic diamniotic twin pregnancy with placental sharing and fetal demise. METHODS This was a prospective longitudinal cohort study of a consecutive series of monochorionic diamniotic twin pregnancies that underwent ultrasound assessments at 12, 16, 20 and 28 weeks' gestation. Fetal biometry (crown-rump length at 12 weeks or estimated fetal weight (EFW) thereafter) and cord insertion sites were recorded at each visit, as well as the diameter of the umbilical vein (UV) in both the intra-abdominal part and a free loop of the umbilical cord. Time-averaged maximum velocity in the intra-abdominal part of the UV was measured to calculate UV-flow. Univariate and multivariate linear regression analyses were performed to assess the relationship between intertwin ratios of these variables and placental sharing at 12, 16, 20 and 28 weeks' gestation. Placental sharing was calculated by dividing the larger by the smaller placental share, as measured on placental injection studies after birth. Additionally, the Mann-Whitney U-test and receiver-operating-characteristics-curve analysis were used to explore the relationship between the occurrence of fetal demise and intertwin differences in fetal biometry, cord insertion sites, UV diameters and flow at 12, 16, 20 and 28 weeks. RESULTS Of 200 consecutive monochorionic twin pregnancies enrolled, injection studies were performed in 165 (82.5%) placentas. On univariate analysis, intertwin differences in fetal biometry, cord insertions and UV variables were associated significantly with placental sharing at 12, 16, 20 and 28 weeks' gestation. On multivariate analysis, intertwin differences in fetal biometry, cord insertions and all three UV variables remained associated significantly with placental sharing at 12 and 16 weeks. However, at 20 and 28 weeks, only the intertwin EFW ratio was associated consistently with placental sharing. Fetal demise of one or both twins complicated 26 (13.0%) pregnancies. Differences in EFW and cord insertion sites were not associated significantly with fetal demise, while at 16 weeks, differences in intra-abdominal UV diameter and flow were associated with an increased risk of subsequent fetal demise. CONCLUSIONS At 12 and 16 weeks' gestation, intertwin differences in UV diameter and flow reflect placental sharing more accurately than do differences in fetal growth and cord insertion sites. At 16 weeks, discordance in intra-abdominal UV diameter and flow is also associated with an increased risk of fetal demise. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Vaccination is a key strategy for controlling the SARS-CoV-2 pandemic. Acceptance of SARS-CoV-2 vaccines by chronically ill patients, such as multiple sclerosis (MS) patients, plays an important role in prevention of complicated disease course. This longitudinal, prospective, multi-centre-study of German MS-patients aimed to detect socio-demographic, clinical, or psychological determinants of attitudes towards standard vaccines, SARS-CoV-2 vaccines, and governmental measures before/during the pandemic. Exactly 404 MS-patients were investigated by standardized questionnaires and structured interviews on socio-demographic, clinical-neurological, and psychological characteristics, vaccination status, and vaccination from June 2019. Data on SARS-CoV-2 vaccination willingness were collected in two follow-up assessments (1st: June to July 2020, before SARS-CoV-2 vaccine availability, N = 200; 2nd: March to May 2021, after SARS-CoV-2 vaccine availability, N = 157). Age, sex, MS course type, depression, and personality characteristics (Extraversion, Novelty seeking, Self-directedness, and Cooperativeness) were significantly associated with vaccination willingness. Although the majority of MS-patients showed SARS-CoV-2 vaccination willingness at both follow-ups (1st: 60%, 2nd: 61%), a substantial proportion had concerns and were undecided or opposed to vaccination. Socio-demographic variables like age and sex, psychopathological status, and various personality characteristics might influence vaccination willingness and should be considered when discussing with MS-patients about SARS-CoV-2 vaccination.

Abstract
Abstract
Background
Accurate stereotactic biopsies of brain tumors are imperative for diagnosis and decisions on therapy. Repetitive needle insertions owing to inconclusive tissue samples enhance increased risks of brain lesioning, hemorrhage and prolonged procedure. Previously we reported on frame-based stereotactic biopsies with a combined 5-ALA fluorescence and laser Doppler flowmetry detection system[1]. The system has now been adapted to frameless navigation with a modified biopsy needle and a new registration system[2].
Material and Methods
Planning was effected with the Medtronic Stealth System. The optical probe was inserted inside the outer cannula of the biopsy needle, which had an opening at the tip, enabling optical measurements ahead of the needle in real-time while manually forwarding it along the trajectory to the target. Fluorescence spectra, microvascular blood flow, and tissue grayness were recorded during insertion. The biopsies were taken where the fluorescence indicated tumor tissue; the optical probe was replaced by the inner cannula. The diagnoses were compared with the fluorescence signals.
Results
In the 9 examined patients the fluorescence measurements and pathological diagnosis of high-grade gliomas or lymphomas matched. Only one needle insertion was necessary. The optical measurements along the trajectory took 5-10 min to the target, the pathological diagnosis was reported after 30-70 min. The probe provided direct feedback of increased blood flow along the trajectory and of malignant tissue in the vicinity of the target.
Conclusion
The optical probe can detect tumor before any tissue is retrieved. If fluorescence is registered, pathological tissue is safely identified. The method can increase the precision and safety of the biopsy and shorten the procedure. The new multimodal probe and the improved registration unit will be tested with other stereotactic and navigation systems and at other neurosurgical centers.
Also, the parallel project on fluorescence guided resection of high-grade gliomas is continued[3].

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
BackgroundAt the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease 2019 (COVID-19) pandemic, the influence of anti-inflammatory therapy on the course of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases (IRD) was unknown. In the meantime, several data indicate an association of severe courses of COVID-19 with the use of rituximab (RTX).ObjectivesTo gather further knowledge about SARS-CoV-2 infections in RTX-treated IRD patients, data from the German COVID-19-IRD-registry were analysed.MethodsHospitalisation was used as a surrogate of COVID-19 severity. Baseline characteristics, disease features, medication and outcome of COVID-19 were compared in RTX-treated inpatients and outpatients.ResultsIn total, 3592 cases were reported in the registry, which included 130 RTX patients (3.6%) for our analysis. RTX-treated inpatients were older than RTX-treated outpatients (median age 63 y vs 56 y, p=0.007). Patients with granulomatosis with polyangiitis treated with RTX (n=32) showed a significant higher COVID-19 related hospitalisation rate (33% vs 11%, p=0.005), which was not the case for patients with rheumatoid arthritis (49% vs 50%). Cardiovascular comorbidities were reported more frequently in hospitalised RTX-treated patients (20% vs. 6%, p=0.032). More than 50% of the RTX-treated inpatients developed COVID-19 related complications, e.g. acute respiratory distress syndrome. The median time period between the last RTX treatment and SARS-CoV-2 infection was shorter in inpatients than in non-hospitalised patients (3 (range 0-17) vs. 4 months (range -29), p=0.039). The COVID-19 related mortality rate was 14% (n=19) in RTX-treated IRD patients. In RTX-treated inpatients and outpatients, there were no relevant differences with respect to the use of concomitant glucocorticoids or other disease modifying anti-rheumatic drugs, disease activity, median last RTX dose or median number of immunomodulatory drugs prior to RTX treatment.ConclusionIn addition to general risk factors, such as age and comorbidities, it is already known that IRD patients treated with RTX show a higher rate of severe COVID-19. In our registry, RTX-treated patients with granulomatosis with polyangiitis appear to be at even higher risk to develop severe COVID-19 compared to other IRD. Moreover, the shorter the time since the last RTX treatment, the higher seems to be the risk of developing severe COVID-19. This might be explained by a more profound B-cell depletion in the first weeks after RTX treatment warranting further studies.Disclosure of InterestsNone declared

Abstract
BackgroundFactors influencing disease activity assessment by patients and physicians are unknown, but are highly relevant in the context of PROs development.ObjectivesTo compare the patients’ and physicians’ global assessment of disease activity in large vessel vasculitis and investigate factors influencing the assessment of disease activity.MethodsBetween 2010 and 2020, patients with large vessel vasculitis and their routine caring physicians assessed a global disease activity score (numerical rating scale 0 – 10) in our outpatient clinic. We compared these global scores of disease activity. In a multiple linear regression analysis we examined the influence of potential demographical and clinical factors on the disease activity assessment.Results138 Patients with 866 assessments were available for analysis. At timepoint of assessment they had a mean age of 76 (± 9) years and a mean disease duration of 5 years (± 5). The median global score of patient-reported disease activity was 3 points, the median physicians’ disease activity assessment was 2 points.In 28,2% (n=244) there was a deviation of more than 2 points between the patients’ and physicians’ assessment of disease activity. Only 5 times the physicians, but 232 times the patients rated their disease activity higher than 5 points.In this group the patient-reported disease activity was associated with the patients age (β 0.025), the patients BMI (β 0.071) and the extent of pain (β 0.19), p<0.05. The disease duration, CRP level and the psychological well-being of the patient showed no association.ConclusionIn our cohort, physicians and patients showed greater divergence in disease activity assessment with higher disease activity. Age, BMI and the extent of pain were associated with higher disease activity ratings by the patients. This results are relevant for the development and interpretation of PROs for activity assessment in large vessel vasculitides.Disclosure of InterestsAnna Kernder: None declared, Marius Rohde: None declared, Hasan Acar: None declared, Oliver Sander Speakers bureau: SOBI Pharma, EUSA Pharma, AbbVie Pharma, Consultant of: SOBI Pharma, EUSA Pharma, Boehringer Pharma, Jutta Richter: None declared, Rebecca Fischer-Betz: None declared, Matthias Schneider Speakers bureau: Astra-Zeneca; Biogen; BMS; Celgene; Chugai; GSK; Janssen-Cilag; Lilly; Pfizer; UCB, Paid instructor for: Lilly, Consultant of: Abbvie; Astra-Zeneca; Boehringer-Ingelheim; GSK; Lilly; Novartis; Pfizer; Protagen; Roche; Sanofi-Aventis; UCB, Grant/research support from: Abbvie; Astra-Zeneca; GSK; UCB, Gamal Chehab: None declared

Abstract
BackgroundSARS-CoV-2 vaccines offer the most effective way to reduce the risk of severe COVID-19. Recent data indicate sufficient immune response after vaccination in most patients with inflammatory rheumatic diseases (IRD) on immunomodulatory treatments.ObjectivesTo investigate the clinical profile of SARS-CoV-2 breakthrough infections among double and triple vaccinated patients with IRD.MethodsData from the German COVID-19-IRD registry, collected by treating rheumatologists between February 2021 and January 2022 were analysed. Patients double or triple vaccinated against COVID-19 ≥14 days prior to proven SARS-CoV-2 infection were identified, and type of IRD, vaccine, immunomodulation, comorbidities and outcome of the infection were compared with 737 unvaccinated IRD-patients with COVID-19.ResultsIn total, 271 cases of breakthrough infections were reported, 250 patients (91%) had received two doses of vaccines, 21 (9%) patients three. More than 70% of the patients received Pfizer/Biontech vaccine for the first, second and third vaccination. The median time from second/third vaccine dose to infection was 148 days (range 14-302) days. Most of the patients were diagnosed with inflammatory joint diseases (Table 1). Most of the patients were treated with methotrexate (Table 1). The use of Januskinase inhibitors(i) was more frequently reported in double vaccinated patients (10.4% vs 4.8%), whereas tumor necrosis (TNF)i were reported more often in triple vaccinated patients (33.3% vs. 22.8). Hospitalisation rate was higher in unvaccinated IRD-patients than in vaccinated ones, while fatality rate was similar in unvaccinated and double vaccinated patients. Although the rate of comorbidities and median age were higher in triple-vaccinated patients, infected patients showed a lower rate of hospitalisation, neither COVID-19 related complications, nor the need of oxygen treatment or death.Table 1.Profile of vaccinated IRD patientsunvaccinated2ndvaccination3rdvaccinationNumber (737)%Number (250)%Number (21)%Age56 (18-93)57 (22-90)63 (35-88)Female47864.915863.21361.9BMI26.8 (17-53)26.7 (17-55)25.4 (18-41)Inflammatory rheumatic disease (multiple selections possible)Inflammatory joint diseases56175.918674.41676.2Connective tissue diseases10112.8301229.6Vasculitis719.6228.8314.3Other IRD638.52911.614.8Immunomodulation (multiple selections possible)Glucocorticoid21228.86726.8523.8Methotrexate27036.69036838.1Azathioprine192.672.8//Cyclosporine30.410.4//Leflunomide506.872.8//Hydroxychloroquine7910.7239.214.8Sulfasalazine202.793.6//JAKi547.32610.414.8TNFi15821.45722.8733.3Abatacept91.231.2//Rituximab212.8114.414.8Other biologics597.93212.829.6Mycophenolate15241.6//Immunoglobulines20.310.4//Apremilast40.5////Cyclophosphamide10.110.4//No immunomodulation7410228.814.8No/low disease activity62584.822389.21885.7Moderate/high disease activity10213.82710.8314.3ComorbiditiesCardiovascular diseases32944.6130521361.9Diabetes mellitus7610.32510//Osteoporosis435.8218.429.5Chronic renal failure405.4166.4419Cancer/history of cancer152.0104314.3COPD253.4104//ILD162.272.8//Bronchial asthma344.6166.4//Pregnancy70.910.414.8No comorbidity25434.59738.8523.8Complications due to COVID-19Hospitalisation13518.32911.629.5Oxygen treatment11415.5249.6//Invasive ventilation253.493.6//Death162.272.8//ConclusionIn this cohort of triple-vaccinated IRD patients no fatal courses and no COVID-19 related complications were reported, although median age and rate of comorbidities were higher compared to double-vaccinated and unvaccinated patients.

Abstract
To optimize gene delivery to myelinating Schwann cells we compared clinically relevant AAV serotypes and injection routes. AAV9 and AAVrh10 vectors expressing either EGFP or the neuropathy-associated gene GJB1/Connexin32 (Cx32) under a myelin specific promoter were injected intrathecally or intravenously in wild type and Gjb1-null mice, respectively. Vector biodistribution in lumbar roots and sciatic nerves was higher in AAVrh10 injected mice while EGFP and Cx32 expression rates and levels were similar between the two serotypes. A gradient of biodistribution away from the injection site was seen with both intrathecal and intravenous delivery, while similar expression rates were achieved despite higher vector amounts injected intravenously. Quantified immune cells in relevant tissues were similar to non-injected littermates. Overall, AAV9 and AAVrh10 efficiently transduce Schwann cells throughout the peripheral nervous system with both clinically relevant routes of administration, although AAV9 and intrathecal injection may offer a more efficient approach for treating demyelinating neuropathies.

Abstract
BACKGROUND Medial patellofemoral ligament reconstruction in skeletally immature patients who experience lateral patellar dislocation has been reported to yield good results. Whether bony abnormalities such as patellar height and trochlear dysplasia should be addressed additionally is a topic of discussion. PURPOSE To evaluate patient-reported outcomes and redislocation rates after isolated medial patellofemoral ligament reconstruction as first-line surgical treatment for lateral patellar dislocation in skeletally immature patients. Further, to analyze epidemiological, intraoperative, and radiographical factors influencing redislocation and clinical outcome. STUDY DESIGN Case series; Level of evidence, 4. METHODS Prospectively collected data were retrospectively analyzed for adolescent patients younger than 16 years who underwent medial patellofemoral ligament reconstruction between 2014 and 2018. Inclusion criteria were isolated medial patellofemoral ligament reconstruction with gracilis tendon and availability of accurate pre- and postoperative radiographs with the presence of open physes. The patients were questioned regarding further surgery, redislocation, and clinical outcomes using the Tegner Activity Scale, International Knee Documentation Committee (IKDC) Subjective Knee Form, Lysholm score, and Kujala score. The influence of diverse epidemiological, intraoperative, and radiographical parameters on the redislocation rates and clinical outcome was analyzed. RESULTS A total of 54 medial patellofemoral ligament reconstructions (49 patients) met the inclusion criteria. After 4.3 ± 1.7 years (range, 2.0-7.3 years), 45 reconstructions (83.3%) in 41 patients were available for follow-up. The distribution of trochlear dysplasia was as follows: type A and B, 19 cases (42.2%) each; type C, 6 cases (13.3%); and type D, 1 case (2.2%). Patellar redislocation occurred in 3 patients (6.7%). The mean Tegner, subjective IKDC, Lysholm, and Kujala scores at follow-up were 6.3 ± 1.6 (range, 3-9), 93.6 ± 8.8, 95.9 ± 7.4, and 97.9 ± 7.1, respectively. Patellar height and trochlear dysplasia had no influence on redislocation or clinical scores. The Lysholm score was lower in knees with intraoperative retropatellar chondral lesion grade ≥III versus grade <III (89.0 ± 19.2 vs 96.9 ± 3.6, respectively; P = .023); likewise, the Kujala score was lower in knees that were grade ≥III versus grade <III (90.0 ± 19.7 vs 98.1 ± 2.1, respectively; P = .015). CONCLUSION Isolated medial patellofemoral ligament reconstruction as first-line surgical treatment in skeletally immature patients yields excellent midterm results, irrespective of patellar height and trochlear dysplasia. Redislocation still occurs in a certain number of patients, and a higher degree of retropatellar chondral lesion is a predictor for a worse clinical outcome.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection represents a serious health risk, especially in chronically ill people. Multiple sclerosis (MS) is the most common chronic immune-mediated neurological disease. Vaccinations play an important role in the therapeutic MS management. This study aimed at determining MS patients' attitudes toward vaccinations and governmental measures before and during the SARS-CoV-2 pandemic, including associations with sociodemographic and clinical variables. METHODS In a longitudinal, multicenter study, 200 MS patients were investigated regarding their vaccination attitudes before and after the first wave of the SARS-CoV-2 pandemic. Data on vaccination status and burden (physical, psychological, and social) experienced as caused by the pandemic and related governmental safety measures were registered. RESULTS Patients with progressive MS felt significantly more pandemic-burdened than patients with relapsing-onset MS (p < 0.001). Older patients were more frequently willing to get vaccinated against SARS-CoV-2 than younger patients (p < 0.001). After the first pandemic wave, patients with pre-pandemic willingness to comply with vaccination recommendations were more likely to accept recommended standard vaccinations (60% vs. 36%) and a possible SARS-CoV-2 vaccination than pre-pandemic nonwilling patients (66.7% vs. 42.0%). CONCLUSIONS The vaccination topic was not immediately present in many patients before the pandemic. MS patients need comprehensive and understandable education meeting their concerns using evidence-based and convincing arguments on the subject of vaccination, particularly younger patients. Older patients are already more often willing to become vaccinated. Complete vaccination status is necessary to avoid multiple infections.

Abstract
BACKGROUND Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease with respect to outcome. Features of the tumor microenvironment (TME) are associated with prognosis when assessed by gene expression profiling. However, it is uncertain whether assessment of the microenvironment can add prognostic information to the most relevant and clinically well-established molecular subgroups when analyzed by immunohistochemistry (IHC). PATIENTS AND METHODS We carried out a histopathologic analysis of biomarkers related to TME in a very large cohort (n = 455) of DLBCL treated in prospective trials and correlated with clinicopathologic and molecular data, including chromosomal rearrangements and gene expression profiles for cell-of-origin and TME. RESULTS The content of PD1+, FoxP3+ and CD8+, as well as vessel density, was not associated with outcome. However, we found a low content of CD68+ macrophages to be associated with inferior progression-free survival (PFS) and overall survival (OS; P = 0.023 and 0.040, respectively) at both univariable and multivariable analyses, adjusted for the factors of the International Prognostic Index (IPI), MYC break and BCL2/MYC and BCL6/MYC double-hit status. The subgroup of PDL1+ macrophages was not associated with survival. Instead, secreted protein acidic and cysteine rich (SPARC)-positive macrophages were identified as the subtype of macrophages most associated with survival. SPARC-positive macrophages and stromal cells directly correlated with favorable PFS and OS (both, P[log rank] <0.001, P[trend] < 0.001). The association of SPARC with prognosis was independent of the factors of the IPI, MYC double-/triple-hit status, Bcl2/c-myc double expression, cell-of-origin subtype and a recently published gene expression signature [lymphoma-associated macrophage interaction signature (LAMIS)]. CONCLUSIONS SPARC expression in the TME detected by a single IHC staining with fair-to-good interobserver reproducibility is a powerful prognostic parameter. Thus SPARC expression is a strong candidate for risk assessment in DLBCL in daily practice.

Abstract
Background:Spondyloarthritis (SpA) is a severe chronic inflammatory disease, which affects quality of life and functional status. It frequently occurs in women of childbearing age. Active disease and TNFi discontinuation at early pregnancy were found to be risk factors for flares during pregnancy (1).Objectives:To compare disease activity during pregnancy in patients with or without bDMARD exposure at conception and during pregnancy and to assess pregnancy outcomes.Methods:RHEKISS is a prospective longitudinal cohort study including patients with confirmed diagnose of inflammatory rheumatic disease. Pregnant patients are eligible to be enrolled until the 20th week of gestation regardless of drug treatment. During observation, information on treatment, disease and pregnancy course, and outcome is collected from rheumatologists and patients. For this analysis, pregnancies of patients with SpA were selected and stratified into three groups according to their exposure to bDMARDs.Results:Of 140 SpA pregnancies included, 74 (53%) were not exposed to bDMARDs at conception (group 1), 38 (27%) were exposed to bDMARDs at conception, but not during pregnancy (group 2) and 28 (20%) were continuously exposed to bDMARDs at conception and during pregnancy (group 3). Certolizumab (50%), Adalimumab (20%), Etanercept (8%) and Infliximab (8%) were the most frequently prescribed bDMARDs at beginning of pregnancy. Baseline characteristics according to treatment exposure are shown in Table 1. Frequency of flares was highest in group 2: 21%, 38%, and 39% of patients flared during the 1st, 2nd, and 3rd trimester. These rates were 20%, 25%, and 21% in group 1 and 8%, 20%, and zero in group 3. The difference in flare rates was also mirrored in the course of physician assessed global disease activity (Figure 1). Whereas patients in group 1 seemed to have a quite stable disease activity during pregnancy, those who were in group 2 had an increasing activity of disease during pregnancy with an even higher increase of disease activity after giving birth. Patients in group 3 had the lowest disease activity.Of 137 singleton pregnancies, 130 (95%) ended in live birth. Of 6 spontaneous abortions 2 were in every of the three groups. One pregnancy in group 1 was terminated in gestational week 22 due to suspect malformation. One baby of the triple pregnancy was born and two aborted. All babies of the twin pregnancies were born healthy.Conclusion:SpA patients treated with bDMARDs at conception are not at higher risk for adverse pregnancy outcomes. Our results in a larger patient population confirmed that discontinuation of bDMARDs after conception is associated with increased disease activity during pregnancy and after birth and a higher risk of flares.References:[1]van den Brandt S et al., Arthritis Res Ther. 2017; 19(1):64.Table 1.Baseline characteristics; numbers are n (%) if not otherwise specified; * value at beginning of pregnancy: first 22 weeks after conceptionParameterno bDMARD at conception (group 1)n=74bDMARD at conception anddiscontinuedduring pregnancy(group 2)n=38bDMARD at conception andcontinuedduring pregnancy (group 3)n=28Totaln=140Singleton72 (97)37 (97.4)28 (100)137 (97.9)Twin1 (1.4)1 (2.6)02 (1.4)Triple1 (1.4)001 (0.7)New-York criteria fulfilled21 (33)17 (49)10 (48)48 (40)disease duration in years, mean (SD)6.4 (5.9)7 (4.1)5.8 (4)6.4 (5.1)age*, mean (SD)33.4 (4.9)32.3 (4)31.6 (3.4)32.7 (4.4)severity of illness*: asymptomatic4 (6)0 (0)3 (14)7 (6) mild31 (48)6 (17)4 (19)41 (34) moderate24 (38)21 (60)14 (67)59 (49) severe5 (8)8 (23)013 (11)HLA-B27 positive41 (62)24 (80)15 (75)80 (69)CRP in mg/l *, mean (SD)6.6 (8.2)5.4 (8.2)5.2 (4.9)6 (7.6)CRP >5mg/l *25 (41)9 (30)8 (35)42 (37)physician global* (NRS 0-10), mean (SD)2.6 (2)2.3 (2.5)1.7 (1.4)2.4 (2.1)BASDAI* (0-10), mean (SD)3.2 (2)2.9 (2.3)2.8 (1.5)3.1 (2)patient global* (NRS 0-10), mean (SD)3.3 (2.7)3 (2.8)3 (2.3)3.1 (2.6)Figure 1Course of physician assessed global disease activityDisclosure of Interests:None declared.

Abstract
Background:Patients with rheumatic and musculoskeletal diseases (RMD) might have an increased risk for infection due to their immunomodulatory treatment, secondary to their disease and comorbidities. Recent studies suggest a decreased risk of severe COVID-19 in RMD-patients treated with biologics.Objectives:The aim of this study was to assess courses of RMD patients treated with TNF-inhibitors (TNF-I) included in the German COVID-19 registry.Methods:In the German physician-reported COVID-19-RMD registry, patients with an RMD and confirmed SARS-CoV-2-infection were documented (data entered between March 30, 2020 and January 30, 2021). We analysed TNF-I treated patients, their course and outcome of the infection. Data were compared to RMD-patients treated with other immunomodulatory drugs (OID) than TNF-I.Results:A total of 269 patients were treated with a TNF-I (57% female) compared to 874 patients who were treated with OID (68% female). Median age was 52 years (range: 19-87) in the TNF-I-group versus 58 years (range: 18-91) in the OID-group. Rheumatoid arthritis was the most common diagnosis (38% in TNF-I-group vs. 52% in the OID-group), followed by ankylosing spondylitis (32% vs. 6%), psoriatic arthritis (22% vs. 11%) and other RMD (9% vs. 31%). Adalimumab (35%) and etanercept (35%) were the most frequently used TNF-I (tab. 1). Glucocorticoids (GC) were used in 22% of TNF-I-treated patients and in 42% of the OID-group.Under TNF-I, stable disease was reported prior to the SARS-CoV-2-infection in 53% of the patients (OID-group: 47%), followed by low disease activity in 35% (OID: 34%), moderate disease activity in 6% (OID: 12%) and high disease activity in 4% (OID: 3%). Most frequent comorbidities were arterial hypertension (29% under TNF-I vs. 35% under OID), diabetes (8% vs. 11%) and cardiovascular diseases (7% vs. 12%).The most common reported COVID-19 symptoms were dry cough (57% vs. 55%), fever (53% vs. 61%) and fatigue (50% vs. 49%). Hospitalization due to SARS-CoV infection was required in only 12% of the TNF-I-treated cases vs. in 29% in the OID-group. Oxygen treatment was necessary in 5% of the patients under TNF-I compared to 22% under OID and invasive ventilation in 2% in the TNF-I-group compared to 6% under OID. Most notably, no fatal courses of COVID-19 were reported among the 269 RMD-patients treated with TNF-I versus 49 deaths in the 874 cases (5.6%) treated with OID. Focussing on the hospitalizated TNF-I patients, the rate of concomitant GC use (p<0.001) and higher disease activity (p=0.005) was significant higher (tab.1).Conclusion:High or moderate RMD-disease activity is an important factor associated with severity of COVID-19 including mortality. In this large cohort RMD patients treated with TNF-I show a low hospitalisation rate and no fatal course. This is reassuring for patients and treating rheumatologists to use TNF-I to control RMD disease activity. The use of glucocorticoids and high disease activity seem to counteract possible protective effects of TNF-I.Table 1.TNF inhibition (269)Other immunomodulation (874)Total patientsRate (%)Total patientsRate (%)Disease activitystable1415340847low933529934Moderate15610812High104293Comorbiditiescardiovascular diseases18710412arterial hypertension772930335bronchial asthma124657COPD/interstitial lung disease1148610chronic renal failure93779Osteoporosis135678Diabetes2289211COVID-19 related symptomsFever1425347855dry cough1525753061Expectoration3112839muscular pain973628032Fatigue1355042449Headache1013823727shortness of breath491824528no symptoms239566COVID-19 outcomeOutpatients2378861971Inpatients321225529need of oxygen treatment18718922invasive ventilation52496fatal course00496TNF inhibitorsAdalimumab9535Infliximab239Certolizumab3312Golimumab249Etanercept9435GC and disease activity in TNF-I treated patientsTNF-I inpatients treated with GC18/3256p< 0.001TNF-I outpatients treated with GC42/23718TNF-I inpatients with high disease activity4/3213TNF-I outpatients with high disease activity6/2376p= 0.005Acknowledgements:The authors would like to thank all physicians and personnel involved in the documentation of the cases in our registry.Disclosure of Interests:None declared

Abstract
Background:The current pandemic constitutes an entirely new situation for patients as well as physicians. The insecurity of the early phase, shutdowns, increasing infection rate and appearing SARS-CoV2 mutations have created a situation that makes live difficult especially for chronic diseases i.e. patients with rheumatic and musculoskeletal diseases (RMD) and their treating physicians. The psychosocial burden that is created by this special situation is completely unknown and is estimated to be higher in patients than in the general population.Objectives:In order to measure the impact on our patients, the German COVID19-Rheuma patient survey was set up in April 2020, during Germany’s first shut down.Methods:The German COVID19-Rheuma patient survey is a patient reported longitudinal online survey where patients with RMD who registered between April and July 2020 are asked on a monthly base using an online survey on social, personal, medical factors, whether a COVID19 infection occurred, isolation measures were changed and scores regarding stress and anxiety are recorded. Between April and July 2020, 637 patients registered and completed a first survey. Up to January 2021, about 400 patients are still enrolled.Here we present an interim analysis of the first 6 months regarding patients that were enrolled in April and May during the first shut-down. This first analysis compares the situation in the first lockdown to July, a phase with very low infection numbers in Germany, and to November, the beginning of the second lockdown.Results:150 patients (87% female) were enrolled in April/early May 2020. Mean age was 48 years (range 11-89). The majority of patients suffered from rheumatoid arthritis (51%), followed by psoriatic arthritis (17%), other spondyloarthropathies (10%) and connective tissue diseases (10%).The majority of patients received antirheumatic therapies: 32% glucocorticoids (GC), 31% cDMARDs, 21% TNF inhibitors, 7% Jak inhibitors, and 9% other biologicals. Of the patients treated with GC, 25% were on GC monotherapy.In the first lockdown, 26% of patients were working remotely and 24% were self-isolating (doubles included). Additionally, 48% were using masks that were not mandatory at that time and 41% were using disinfection in a regular manner. The rates for remote work and self-isolation did not change significantly over time while the mask use increased to 98% with the official obligation to do so. The use of disinfectants increased to 88% in November.Regarding disease activity, no change in patient global assessment could be observed over time (4.3 ± 2.5 vs. 4.0 ±2.6 and 4.0 ± 2.5). Self-reported pain was also stable over time as were sleep disturbances. While 48.2% of patients who were receiving physiotherapy paused in April, only 10 and 14% did so in July and November, respectively. 11% of the patients paused their medication in the first lockdown, whereas only 2.75% did so in July and 3.4% in November. Contact with the treating rheumatologist was maintained over time in the majority of cases.Conclusion:While in the beginning of the pandemic the insecurity was considerable and the concern that the fear for infection would lead to inadequately treated patients with RMDs, we here show for the first time that on the one hand our patients were timely in taking adequate measures to keep themselves safe (e.g. self-isolating, mask use) and adapted to the clinical situation in not pausing their medication. Altogether, in this alert cohort, the pandemic did not lead to an increase of patient-reported disease activity in the first six months.Acknowledgements:Thanks goes to all patients who participated in the study.Disclosure of Interests:None declared

Abstract
Background Abnormal intracranial findings are often detected at mid‐trimester ultrasound (US) in fetuses with myelomeningocele (MMC). It is unclear whether these findings constitute a spectrum of the disease or are an independent finding, which should contraindicate fetal surgery. Objective To ascertain the spectrum and frequency of US‐detected cranial findings in fetuses with MMC. Search strategy MEDLINE, Embase, Web of Science and CENTRAL were searched from January 2000 to June 2020. Selection criteria Study reporting incidence of cranial US findings in consecutive cases of second‐trimester fetuses with MMC. Data collection and analysis Publication quality was assessed by Newcastle–Ottawa Scale (NOS) and modified NOS. Meta‐analysis could not be performed as a result of high clinical diversity and study heterogeneity. Main results Fourteen cranial US findings were reported in 15 studies. Findings in classic Chiari II malformation (CIIM) spectrum included posterior fossa funnelling (96%), small transcerebellar diameter (82–96%), ‘banana’ sign (50–100%), beaked tectum (65%) and ‘lemon’ sign (53–100%). Additional cranial findings were small biparietal diameter (BPD) and head circumference (HC) (<5th centile; 53 and 71%, respectively), ventriculomegaly (45–89%), abnormal pointed shape of the occipital horn (77–78%), thinning of the posterior cerebrum, perinodular heterotopia (11%), abnormal gyration (3%), corpus callosum disorders (60%) and midline interhemispheric cyst (42%). Conclusions We identified 14 cranial findings by second‐trimester US in fetuses with MMC. The relatively high incidence of these findings and their unclear prognostic significance might not contraindicate fetal surgery in the case of normal fetal genetic testing. Some cranial findings may independently affect postnatal outcome, however. Long‐term detailed follow‐up is required to investigate this. Tweetable abstract A high rate of cranial abnormalities found on second‐trimester ultrasound in fetuses with myelomeningocele. A high rate of cranial abnormalities found on second‐trimester ultrasound in fetuses with myelomeningocele.

Abstract
Problems and complications concerning the patellar fixation in medial patellofemoral ligament reconstruction (MPFLR) have been reported. The purpose of this retrospective study was to systematically analyze the surgical technique for MPFLR with a V: -shaped patellar bonetunnel for implant-free fixation of an autologous gracilis tendon, allowing early functional rehabilitation, regarding restoration of the patellofemoral stability, patient satisfaction, return to sports, and technique-specific complications. In 2010, 128 cases of consecutive isolated MPFLR were performed. All these cases were included. After a minimum follow-up of 3 years, 104 cases were retrospectively analyzed (follow-up: 81.3%) with regard to redislocation, subjective functional outcome (Tegner's score and sports level compared with preoperative level), patient satisfaction, revision surgery, and technique-specific complications. After a follow-up of 45.7 ± 3.2 months, 101 of 104 cases (97.1%) showed no redislocation. Mean Tegner's score was 5.1 ± 1.8 (range, 2-9). A total of 61.5% patients reported about a higher sports level compared with their preoperative level. The patient satisfaction was high with 94.2%. In two cases (1.9%), technique-specific problems occurred as the bone bridge of the V: -shaped tunnel was insufficient due to a malpositioning of the aiming device. No further technique-specific problems occurred and no revision surgery was necessary during the observational period. The presented surgical technique is safe and it reliably restores the patellofemoral stability, with a low rate of redislocations, an excellent subjective functional outcome, and a high-patient-reported satisfaction. No major technique-specific complications occurred.

Abstract
Polymerase chain reaction (PCR) detection has become the gold standard for diagnosis and typing of enterovirus (EV) and human parechovirus (HPeV) infections. Its effectiveness depends critically on using the appropriate sample types and high assay sensitivity as viral loads in cerebrospinal fluid samples from meningitis and sepsis clinical presentation can be extremely low. This study evaluated the sensitivity and specificity of currently used commercial and in-house diagnostic and typing assays. Accurately quantified RNA transcript controls were distributed to 27 diagnostic and 12 reference laboratories in 17 European countries for blinded testing. Transcripts represented the four human EV species (EV-A71, echovirus 30, coxsackie A virus 21, and EV-D68), HPeV3, and specificity controls. Reported results from 48 in-house and 15 commercial assays showed 98% detection frequencies of high copy (1000 RNA copies/5 µL) transcripts. In-house assays showed significantly greater detection frequencies of the low copy (10 copies/5 µL) EV and HPeV transcripts (81% and 86%, respectively) compared with commercial assays (56%, 50%; P = 7 × 10-5 ). EV-specific PCRs showed low cross-reactivity with human rhinovirus C (3 of 42 tests) and infrequent positivity in the negative control (2 of 63 tests). Most or all high copy EV and HPeV controls were successfully typed (88%, 100%) by reference laboratories, but showed reduced effectiveness for low copy controls (41%, 67%). Stabilized RNA transcripts provide an effective, logistically simple and inexpensive reagent for evaluation of diagnostic assay performance. The study provides reassurance of the performance of the many in-house assay formats used across Europe. However, it identified often substantially reduced sensitivities of commercial assays often used as point-of-care tests.

Abstract
OBJECTIVES To explore the association between fetal umbilical and middle cerebral artery (MCA) Doppler abnormalities and outcome in late preterm pregnancies at risk of fetal growth restriction. METHODS This was a prospective cohort study of singleton pregnancies at risk of fetal growth restriction at 32 + 0 to 36 + 6 weeks of gestation, enrolled in 33 European centers between 2017 and 2018, in which umbilical and fetal MCA Doppler velocimetry was performed. Pregnancies were considered at risk of fetal growth restriction if they had estimated fetal weight and/or abdominal circumference (AC) < 10th percentile, abnormal arterial Doppler and/or a fall in AC growth velocity of more than 40 percentile points from the 20-week scan. Composite adverse outcome comprised both immediate adverse birth outcome and major neonatal morbidity. Using a range of cut-off values, the association of MCA pulsatility index and umbilicocerebral ratio (UCR) with composite adverse outcome was explored. RESULTS The study population comprised 856 women. There were two (0.2%) intrauterine deaths. Median gestational age at delivery was 38 (interquartile range (IQR), 37-39) weeks and birth weight was 2478 (IQR, 2140-2790) g. Compared with infants with normal outcome, those with composite adverse outcome (n = 93; 11%) were delivered at an earlier gestational age (36 vs 38 weeks) and had a lower birth weight (1900 vs 2540 g). The first Doppler observation of MCA pulsatility index < 5th percentile and UCR Z-score above gestational-age-specific thresholds (1.5 at 32-33 weeks and 1.0 at 34-36 weeks) had the highest relative risks (RR) for composite adverse outcome (RR 2.2 (95% CI, 1.5-3.2) and RR 2.0 (95% CI, 1.4-3.0), respectively). After adjustment for confounders, the association between UCR Z-score and composite adverse outcome remained significant, although gestational age at delivery and birth-weight Z-score had a stronger association. CONCLUSION In this prospective multicenter study, signs of cerebral blood flow redistribution were found to be associated with adverse outcome in late preterm singleton pregnancies at risk of fetal growth restriction. Whether cerebral redistribution is a marker describing the severity of fetal growth restriction or an independent risk factor for adverse outcome remains unclear, and whether it is useful for clinical management can be answered only in a randomized trial. © 2020 The Authors.

Abstract
PURPOSE To analyse 1000 consecutive patients, treated with isolated or combined posterior cruciate ligament (PCL) reconstruction in a single centre according to the epidemiological factors and differences in injury patterns depending on the activity during trauma. METHODS Between 2004 and 2019, one thousand isolated and combined PCL reconstructions were performed. The medical charts and surgical reports of all patients were analysed regarding epidemiological factors. The PCL lesions were divided into isolated and combined lesions with at least one additional ligamentous injury. The influence of activity during accident and additional injury on the presence of isolated or combined lesions and injury patterns was calculated. RESULTS In 388 patients (38.8%), sporting activity was the main activity in PCL lesions, followed by traffic accidents in 350 patients (35.0%). Combined injuries were present in 227 patients (58.5%) with sports injuries and 251 patients (71.7%) with traffic accidents. Only during handball, an isolated PCL lesion (69.1%) was more common than a combined lesion. Highest rate of combined lesions was present in car accidents (91.7%). In all activities except skiing and biking, the most common additional peripheral injury was a tear of the posterolateral corner. In skiing and biking accidents, the most common additional peripheral lesion was a lesion of the medial collateral ligament. In patients with PCL lesion and additional fracture of the same lower extremity, a combined lesion was more common than an isolated lesion (p = 0.001). CONCLUSION Combined PCL lesions are more common than isolated lesions, even in sports injuries (except handball). Incidence and injury pattern vary depending on activity during trauma. Main additional peripheral lesion is a lesion of the posterolateral corner, except biking and skiing accidents where a medial lesion is more common. LEVEL OF EVIDENCE Level III.

Abstract
Background:Patients with systemic lupus erythematosus (SLE), even compared to those with other rheumatic diseases, are thought to often experience a long delay from the onset of symptoms to diagnosis.Objectives:Our aim was to study the association of this delay to the long-term outcome of the disease.Methods:Information on demographics, onset of first symptoms, first physicians visit, time of diagnosis and organ involvement was assessed by self-reported questionnaires among SLE patients in Germany in 2011 (LuLa cohort, n=585). Disease related damage (Brief Index of Lupus Damage; BILD), disease activity (Systemic Lupus Activity Questionnaire; SLAQ) and health related quality of life (SF-12) were chosen as proxies for outcome. The association to the outcome of the disease was analyzed by linear regression analysis, adjusted for age, disease duration, organ involvement and sex.Results:In our cohort, the mean reported duration between the onset of symptoms and the diagnosis of SLE was 46 months (SD 73), which includes 13 months (SD 41) between the onset of symptoms and the first physicians visit. The participating patients were diagnosed between 1960 and 2004.Linear regression analysis revealed that longer time to diagnosis was associated with (i) higher disease activity (SLAQ, p<0.0001, β=0.199), (ii) higher disease-related damage (BILD, p=0.002, β=0.137) and (iii) lower health-related quality of life (SF-12 physical p=0.004, β=-0.136, SF-12 mental p=0.004, β=-0.143) in the year 2011. The organ involvement at the time of diagnosis did not alter these results.Conclusion:A delay in diagnosis was associated with a worse outcome in SLE (disease activity, disease-related damage and health-related quality of life). Therefore, an early diagnosis seems to be important to improve the long-term outcome of the disease. It will be interesting to see whether adopting the new EULAR/ACR 2019 classification criteria can contribute to a faster diagnosis and a better outcome in consequence.The LuLa study is supported by unrestricted grants from GlaxoSmithKline and UCB Pharma.Disclosure of Interests:Anna Kernder Grant/research support from: Grant/research support from: GlaxoSmithKline and UCB Pharma for performing the LuLa-study., Jutta Richter Grant/research support from: Grant/research support from: GlaxoSmithKline and UCB Pharma for performing the LuLa-study., Rebecca Fischer-Betz Consultant of: UCB, Speakers bureau: Abbvie, Amgen, Biogen, BMS, Celgene, Chugai, GSK, Janssen, Lilly, Medac, MSD, Novartis, Roche, UCB, Pfizer., Borgi Winkler-Rohlfing: None declared, Martin Aringer Consultant of: Boehringer Ingelheim, Roche, Speakers bureau: Boehringer Ingelheim, Roche, Matthias Schneider Grant/research support from: GSK, UCB, Abbvie, Consultant of: Abbvie, Alexion, Astra Zeneca, BMS, Boehringer Ingelheim, Gilead, Lilly, Sanofi, UCB, Speakers bureau: Abbvie, Astra Zeneca, BMS, Chugai, GSK, Lilly, Pfizer, Sanofi, Gamal Chehab Grant/research support from: Grant/research support from: GlaxoSmithKline and UCB Pharma for performing the LuLa-study.

Abstract
Background:Patients with inflammatory rheumatic diseases (IRD) and infection with SARS-CoV-2 may be at risk to develop a severe course of COVID-19. To gather knowledge about SARS-CoV-2 infections in IRD patients, a national registry was established to elucidate IRD specific profiles of COVID-19.Objectives:To identify risk factors for hospitalisation.Methods:Patients from the German registry on SARS-CoV-2 infection in IRD were analysed. Patients are enrolled with a pre-existing IRD and a positive lab-result for a SARS-CoV-2 infection. The main outcome parameter was hospitalisation versus non-hospitalisation. Multivariable logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Covariates included in the model were age group, gender, key comorbidities (cardiovascular, lung diseases, chronic renal insufficiency), prior and/or current use of glucocorticosteroids (GC) or NSAIDs and remission.Results:Until May 17th, 2020, data from 192 IRD patients with SARS-CoV-2 infection were reported (67 males; 124 females; 1 diverse). 64 patients were hospitalised, 21 patients were ventilated non-invasively/invasively and 15 patients died.Baseline characteristics are shown in table 1, stratified into the patient groups non-hospitalisation, hospitalisation without ventilation, and hospitalisation with ventilation. Non-hospitalised patients were younger, had less comorbidities and were less often treated with GC. In the group of hospitalised patients compared to non-hospitalised patients more patients were male (42% vs 32% male) with an even higher proportion in the ventilated patient group (57% male).In the multivariable logistic regression model, age>65 years (OR 5.1; 95%CI 2.3-11.4), cardiovascular comorbidity (OR 2.3; 95%CI 1.0-5.0), and prior and/or current treatment with GC (OR 2.6; 95%CI 1.2-5.4) were independently associated with hospitalisation.Parameter, N (%)Non-hospitalisation128 (66.7)Hosp. without ventilation42 (22.4)Hosp. with ventilation21 (10.9)Age [years], mean (SD)53.8 (13.4)65.2 (15.5)69.7 (9.9)Female87 (68.5)28 (65.1)9 (42.9)RA60 (46.9)24 (55.8)12 (57.1)Psoriasis23 (18)3 (7)3 (14.3)Axial spondyloarthritis14 (10.9)2 (4.7)0Lupus7 (5.5)1 (2.3)0Remission of IRD67 (52.3)23 (53.5)4 (19)Number of comorbidities, mean (SD)1 (1.2)1.8 (1.4)2.4 (1.5)Cardiovascular disease42 (32.8)25 (58.1)16 (76.2)Pulmonary disease16 (12.5)8 (18.6)8 (38.1)Chronic renal insufficiency5 (3.9)7 (16.3)4 (19)Cancer2 (1.6)4 (9.3)2 (9.5)Obesity (BMI>30)23 (18)5 (11.6)3 (14.3)Diabetes3 (2.3)7 (16.3)4 (19)Other comorbidities20 (15.6)9 (20.9)6 (28.6)csDMARD (without HCQ)59 (46.1)25 (58.1)8 (38.1)HCQ13 (10.2)1 (2.3)2 (9.5)bDMARD48 (37.5)15 (34.9)8 (38.1)tsDMARD5 (3.9)1 (2.3)1 (4.8)Glucocorticosteroids47 (37)29 (67.4)13 (61.9)NSAIDs21 (16.4)5 (11.6)1 (4.8)Conclusion:As has been described for COVID-19 in general, also in IRD male gender may be associated with a more severe course of the infection as the descriptive analysis of data shows.

Abstract
The therapeutic landscape of chronic myeloid leukemia (CML) has profoundly changed over the past 7 years. Most patients with chronic phase (CP) now have a normal life expectancy. Another goal is achieving a stable deep molecular response (DMR) and discontinuing medication for treatment-free remission (TFR). The European LeukemiaNet convened an expert panel to critically evaluate and update the evidence to achieve these goals since its previous recommendations. First-line treatment is a tyrosine kinase inhibitor (TKI; imatinib brand or generic, dasatinib, nilotinib, and bosutinib are available first-line). Generic imatinib is the cost-effective initial treatment in CP. Various contraindications and side-effects of all TKIs should be considered. Patient risk status at diagnosis should be assessed with the new EUTOS long-term survival (ELTS)-score. Monitoring of response should be done by quantitative polymerase chain reaction whenever possible. A change of treatment is recommended when intolerance cannot be ameliorated or when molecular milestones are not reached. Greater than 10% BCR-ABL1 at 3 months indicates treatment failure when confirmed. Allogeneic transplantation continues to be a therapeutic option particularly for advanced phase CML. TKI treatment should be withheld during pregnancy. Treatment discontinuation may be considered in patients with durable DMR with the goal of achieving TFR.

Abstract
OBJECTIVE All arthroscopic treatment of deep cartilage defects in the knee for reconstruction of the articular surface. INDICATIONS Focal cartilage defects of the knee (ICRS ≥ grade 3) from a size of 2.5 cm2 and more. CONTRAINDICATIONS Osteoarthritis (Kellgren-Lawrence > grade 2), osseus defect situation, cartilage lesion of the opposing articular surfaces (ICRS > grade 2), instability, malalignment (>3-4°), inflammatory joint diseases. SURGICAL TECHNIQUE First procedure (cell harvesting): Treatment of additional pathologies, preparation of the cartilage defect, harvesting of osteochondral cylinders for cell culture. Second procedure (cell implantation): Dry arthroscopy, cleaning and drying of the already prepared defect, implantation of the in situ crosslinking cartilage cell suspension. POSTOPERATIVE MANAGEMENT First procedure (cell harvesting): Early functional treatment with weight bearing as tolerated. Second procedure (cell implantation): No drains, extension brace for 4 days, then free range of motion, partial weight bearing for 4 weeks in patellofemoral implantation and for 8 weeks in tibiofemoral implantation, continuous passive motion beginning in postoperative week 2, cycling from postoperative week 9. RESULTS In the literature, results for ACI in the knee are reported to be good, especially for larger cartilage defects. Arthroscopic techniques should lead to a decrease of complications and perioperative morbidity. No technique-specific complications occurred in our cohort. From 2012-2015, 98 patients were treated using the above mentioned technique, whereby 62 patients were retrospectively evaluated after 31.0 ± 14.8 (12.5-61.4) months. In 15 patients (28%) additional procedures were performed (7 anterior cruciate ligament reconstructions, 3 correction osteotomies and 5 medial patellofemoral ligament reconstructions). Average cartilage defect size was 4.7 ± 2.8 cm2, in 18 patients (29%) more than one cartilage defect was treated. The subjective IKDC and total KOOS scores resulted in 66 ± 10 and 73 ± 19 points.

Abstract
X-linked Charcot-Marie-Tooth disease (CMT1X), one of the commonest forms of inherited demyelinating neuropathy, results from GJB1 gene mutations causing loss of function of the gap junction protein connexin32 (Cx32). The aim of this study was to examine whether delayed gene replacement therapy after the onset of peripheral neuropathy can provide a therapeutic benefit in the Gjb1-null/Cx32 knockout model of CMT1X. After delivery of the LV-Mpz.GJB1 lentiviral vector by a single lumbar intrathecal injection into 6-month-old Gjb1-null mice, we confirmed expression of Cx32 in lumbar roots and sciatic nerves correctly localized at the paranodal myelin areas. Gjb1-null mice treated with LV-Mpz.GJB1 compared with LV-Mpz.Egfp (mock) vector at the age of 6 months showed improved motor performance at 8 and 10 months. Furthermore, treated mice showed increased sciatic nerve conduction velocities, improvement of myelination and reduced inflammation in lumbar roots and peripheral nerves at 10 months of age, along with enhanced quadriceps muscle innervation. Plasma neurofilament light (NEFL) levels, a clinically relevant biomarker, were also ameliorated in fully treated mice. Intrathecal gene delivery after the onset of peripheral neuropathy offers a significant therapeutic benefit in this disease model, providing a proof of principle for treating patients with CMT1X at different ages.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
BACKGROUND Young patients with severe medial osteoarthritis, varus malalignment and insufficiency of the anterior cruciate ligament (ACL) are difficult to treat. The tibial slope has gained attention with regard to osteotomies and ligamentous instability. The purpose was to evaluate the outcome of combined high tibial osteotomy (HTO), ACL reconstruction and chondral resurfacing (CR, abrasion plus microfracture), and to analyse graft failure rates with regard to the tibial slope. METHODS Fifty cases (48.9 ± 5.4 years) of combined HTO, ACLR and CR were retrospectively analysed with regard to survival, functional outcome (subjective International Knee Documentation Committee (IKDC) examination form) and subjective satisfaction. The tibial slope was determined on lateral radiographs and analysed with regard to its influence on graft functionality at the time of hardware removal. RESULTS Follow-up rate was 100% after 5.6 ± 1.6 years. No arthroplasties were performed. Subjective IKDC score was 70 ± 18, and 94% were satisfied with the result. The graft was intact in 39 cases (78%), and non-functional in 11 cases (22%). No significant changes were present in pre- and postoperative tibial slope (P = 0.811). Graft insufficiency was strongly dependent on tibial slope, with a failure rate of seven percent in cases of postoperative tibial slope <7.5°, 24% in cases of 7.5-12.5°, and 36% in cases of >12.5°. CONCLUSION Combined HTO, ACLR and CR is an effective treatment in these cases. The graft failure rate increases with an increase in tibial slope, in particular when exceeding 12.5°.

Abstract
Motivation Molecular signatures for treatment recommendations are well researched. Still it is challenging to apply them to data generated by different protocols or technical platforms. Results We analyzed paired data for the same tumors (Burkitt lymphoma, diffuse large B-cell lymphoma) and features that had been generated by different experimental protocols and analytical platforms including the nanoString nCounter and Affymetrix Gene Chip transcriptomics as well as the SWATH and SRM proteomics platforms. A statistical model that assumes independent sample and feature effects accounted for 69–94% of technical variability. We analyzed how variability is propagated through linear signatures possibly affecting predictions and treatment recommendations. Linear signatures with feature weights adding to zero were substantially more robust than unbalanced signatures. They yielded consistent predictions across data from different platforms, both for transcriptomics and proteomics data. Similarly stable were their predictions across data from fresh frozen and matching formalin-fixed paraffin-embedded human tumor tissue.

Abstract
BACKGROUND High tibial osteotomy (HTO) is a widely used treatment option for medial osteoarthritis and varus malalignment, especially in young patients with early osteoarthritis. Limited outcome data are available for this procedure in severe osteoarthritis, and no long-term data are available using newer implants. PURPOSE To determine survivorship and functional results of medial open-wedge HTO combined with a chondral resurfacing (CR) procedure (abrasion plus microfracture) in severe medial osteoarthritis (Kellgren-Lawrence grade 3 and 4) and varus malalignment. Furthermore, factors that potentially influence the outcome were analyzed. STUDY DESIGN Case series; Level of evidence, 4. METHODS From September 2005 to December 2008, all cases of HTO (fixation with an angular-stable internal fixator) combined with CR were prospectively surveyed with regard to survival (Kaplan-Meier-method, not requiring arthroplasty) and functional outcome (subjective International Knee Documentation Committee [IKDC] score). Cartilage regeneration at the time of hardware removal, tibial bone varus angle (TBVA), pre- and postoperative mechanical medial proximal tibial angle (MPTA), and postoperative alignment were analyzed with regard to the result. RESULTS Seventy-nine knees were included (73 patients; mean age 50.9 ± 7.6 years). The follow-up rate was 90% at 10.0 ± 1.2 years (range, 8.3-12.1 years). Pre- and postoperative mechanical tibiofemoral axis were 9.6° ± 3.0° of varus and 0.6° ± 2.7° of valgus, respectively. Survival rate was 81.7% (95% CI, 72.5%-90.9%) at 10 years. Subjective IKDC score significantly improved from 44 ± 11 preoperatively to 70 ± 13 at one, 66 ± 15 at three, 66 ± 15 at five, and 65 ± 17 at ten years ( P < .001 at any point of follow-up). Poor cartilage regeneration and low preoperative IKDC score (<40) were associated with decreased survival. High preoperative TBVA was associated with better and an overcorrected MPTA (>95°) with inferior functional outcome at final follow-up, respectively. CONCLUSION Even in cases of severe medial osteoarthritis and varus malalignment, HTO in combination with a CR procedure is a good to excellent treatment option. The role of the CR procedure remains unclear. Although good results are obtained with overcorrected MPTA, long-term functional outcome is inferior.
