Does Gender Influence Outcome in Cartilage Repair Surgery? An Analysis of 4,968 Consecutive Patients from the German Cartilage Registry (Knorpel Register DGOU)

The goal was to examine gender differences of patient characteristics and outcome after cartilage repair based on a collective of nearly 5,000 patients. Patient characteristics, accompanying therapies, and outcome (Knee Injury and Osteoarthritis Outcome Score [KOOS], reoperations, patient satisfaction) of 4,986 patients of the German cartilage register DGOU were assessed by t test for possible gender differences. P values <0.05 were considered statistically significant. Women were older than men (38.07 ± 12.54 vs. 26.94 ± 12.394 years, P = 0.002), more often preoperated (0.30 ± 0.63 vs. 0.24 ± 0.55, P = 0.001), and had a longer symptom duration (25.22 ± 41.20 vs. 20.67 ± 35.32 months, P < 0.001). Men had greater mean leg axis malalignment than women (3.24° ± 3.26° vs. 2.67° ± 3.06°, P < 0.001), less favorable meniscal status ( P = 0.001), worse defect stage ( P = 0.006), and a more severely damaged corresponding articular surface ( P = 0.042). At baseline (59.84 ± 17.49 vs. 52.10 ± 17.77, P < 0.001), after 6 months (72.83 ± 15.56 vs. 66.56 ± 17.66, P < 0.001), after 12 months (77.88 ± 15.95 vs. 73.07 ± 18.12, P < 0.001), and after 24 months (79.311 ± 15.94 vs. 74.39 ± 18.81, P < 0.001), men had better absolute KOOS values, but women had better relative KOOS increases 6 months (14.59 ± 17.31 vs. 12.49 ± 16.3, P = 0.005) as well as 12 months postoperatively (20.27 ± 18.6 vs. 17.34 ± 17.79, P = 0.001) compared with preoperatively, although 12 and 24 months postoperatively they were subjectively less satisfied with the outcome ( P < 0.001) and had a higher reintervention rate at 24 months (0.17 ± 0.38 vs. 0.12 ± 0.33, P = 0.008). In summary, the present work shows specific gender differences in terms of patient characteristics, defect etiology, defect localization, concomitant therapy, and the choice of cartilage repair procedure. Unexpectedly, contrary to the established scientific opinion, it could be demonstrated that women show relatively better postoperative KOOS increases, despite a higher revision rate and higher subjective dissatisfaction.

Introduction : The purpose of this study is to determine the degree of gender differences in lay person recognition, emergency medical services (EMS) activation, and the prehospital management of STEMI. Methods : Data were gathered prospectively from May 1999 to January 2007 on consecutive patients with STEMI who presented to a tertiary care hospital emergency department. Patients arriving by ambulance and private vehicle were included. Data collection included determining symptom duration, whether a prehospital ECG was obtained, whether the cardiac interventional lab was activated prior to patient arrival at the hospital, patient age, and hospital length of stay. Prehospital activation of the cath lab was done by emergency medicine based on paramedic ECG interpretation in consultation with cardiology. Statistical analysis was performed using the Mann-Whitney U test, the Yates-corrected chi-square test, and linear regression. Results : A total of 3260 cases were studied, of which, 3097 had complete data for analysis. Only EMS cases were included in the ECG analysis, and only patients having a prehospital ECG were included in the prehospital activation of cath lab analysis. Regression analysis showed that older age and female gender were significant predictors of access and arrival by EMS. The mean age in years was higher for EMS arrival (69 women; 59 men) than for private vehicle (62 women; 56 men). Conclusion : Women with STEMI tend to use EMS more frequently then men, but are older and wait longer before seeking treatment. Whether these factors contribute to the longer length of stay remains to be determined.

Objective The main purpose of the present study was to assess the risk for major revision surgery after perichondrium transplantation (PT) at a minimum of 22 years postoperatively and to evaluate the influence of patient characteristics. Design Primary outcome was treatment success or failure. Failure of PT was defined as revision surgery in which the transplant was removed, such as (unicondylar) knee arthroplasty or patellectomy. The functioning of nonfailed patients was evaluated using the International Knee Documentation Committee (IKDC) score. In addition, the influence of patient characteristics was evaluated. Results Ninety knees in 88 patients, aged 16 to 55 years with symptomatic cartilage defects, were treated by PT. Eighty knees in 78 patients were eligible for analysis and 10 patients were lost to follow-up. Twenty-eight knees in 26 patients had undergone major revision surgery. Previous surgery and a longer time of symptoms prior to PT were significantly associated with an increased risk for failure of cartilage repair. Functioning of the remaining 52 patients and influence of patient characteristics was analyzed using their IKDC score. Their median IKDC score was 39.08, but a relatively young age at transplantation was associated with a higher IKDC score. Conclusions This 22-year follow-up study of PT, with objective outcome parameters next to patient-reported outcome measurements in a unique group of patients, shows that overall 66% was without major revision surgery and patient characteristics also influence long-term outcome of cartilage repair surgery.

Objective We sought to determine whether rates of postoperative arthrofibrosis following tibial tuberosity osteotomy (TTO) with complete mobilization of the fragment (TTO-HD) are comparable to TTOs where the hinge remained intact (TTO-HI). Design Patients who underwent TTO with concomitant cartilage repair procedure between January 2007 and May 2017, with at least 2 years of follow-up were included in this study. Postoperative reinterventions following TTO-HD and TTO-HI were assessed and multivariant logistic regression models were used to identify whether postoperative reinterventions can be attributed to either technique when controlled for defect size or defect number. Results A total of 127 patients (TTO-HD, n = 80; TTO-HI, n = 47) were included in this study. Significantly more patients in the TTO-HD group (31.2%) developed postoperative arthrofibrosis compared with TTO-HI (6.4%; P < 0.05). Multivariant logistic regression revealed that TTO-HD is an independent risk factor for predicting postoperative arthrofibrosis (OR 6.5, CI = 1.7-24.2, P < 0.05). Conclusion Patients who underwent TTO with distal hinge detachment and a proximally flipped tubercle for better exposure during concomitant cartilage repair were at a significantly higher risk of postoperative arthrofibrosis than patients with similar size and number of defects treated without mobilization of the tubercle. While certain procedures can benefit from larger exposure, surgeons should be aware of the increased risk of postoperative arthrofibrosis. Level of Evidence Level III, case-control study.

Preoperative Analysis

Aims and Objectives: In the context of cartilage repair, identification of the underlying pathologies depends on detailed preoperative evaluation. High tibial osteotomy (HTO) for varus deformities is one of the most common concomitant treatments, though scientific evidence about efficiency of concomitant HTO is still limited. The present study was initiated to describe preoperative analysis of alignment and to analysis outcome comparing patients with combined cartilage repair and HTO with those who received cartilage repair procedures alone. Materials and Methods: The multicenter data (3855 data sets on April 15, 2018) was provided by the attending physician and a self-reported outcome analysis (KOOS). Inclusion criteria: Existence of a leg full length portrait, a single defect at the medial femoral condyle, either no accompanying surgery or a HTO and information on leg axis misalignment. For outcome evaluation patients were divided into three different groups with regard to the extent of varus deformity: MILD (0-4° varus), MODERATE (5-9° varus) and SEVERE (> 10°). Statistical Analysis was performed using SPSS (IBM) Version 23. For detection of significances between different groups one-way ANOVA test was applied. P-values < 0.05 were considered statistical significant. Results: In 55.1% (n=2125) of the patients a full leg weight-bearing radiographs has been performed preoperatively. Out of these 834 (39%) cases with isolated defects of the medial femoral condyle have been identified of which 179 received HTO in combination with the cartilage repair procedure (21.5%), while 411 cases have been treated with isolated cartilage repair (49.3%). From the remaining 385 patients, 256 patients were considered MILD (67,3%), 113 MODERATE (29.5%) and 4.2% (n=16) SEVERE. Incidence of HTO significantly depended on the degree of varus deformity for mild (19% HTO) and moderate (83% HTO) deformity, but there was no significance between the moderate and severe (81% HTO) group. Significant differences of the KOOS score could be shown preoperatively between the mild (mean: 57.3), as well as moderate (mean: 55.95), and the severe group (mean 39.53) and six months postoperatively between the mild (mean: 71.48) and the severe (mean: 52.6) group. Conclusion: The present analysis of a large patients cohort extracted from the German Cartilage Registry (KnorpelRegister DGOU) demonstrates that, against common guidelines, full-leg weigth-bearing radiographs are not conducted on a regular basis in patients assigned for cartilage repair procedures. In those cases with detailed preoperative analysis of alignment, the degree of deformity seems to influence the decision, whether a realignment procedure (HTO) is performed. For the moderate subgroup a trend towards better clinical outcome was found for combined treatment in terms of realignment and cartilage repair in comparison to cartilage repair alone. Since there was no difference in the MILD subgroup, more evidence is needed to proof, whether those patients benefit from a HTO or not.

How is credit for group work allocated when individual contributions are not observed? I use data on academics' publication records to test whether demographic traits like gender influence how credit is allocated under such uncertainty. While solo-authored papers send a clear signal about ability, coauthored papers are noisy, providing no specific information about each contributor's skills. I find that men are tenured at roughly the same rate regardless of coauthoring choices. Women, however, are less likely to receive tenure the more they coauthor. The result is much less pronounced among women who coauthor with other women.

Ciguatera poisoning is a globally occurring seafood disease caused by the ingestion of marine products contaminated with dinoflagellate produced neurotoxins. Persistent forms of ciguatera, which prove to be highly debilitating, are poorly studied and represent a significant medical issue. The present study aims to better understand chronic ciguatera manifestations and identify potential predictive factors for their duration. Medical files of 49 patients were analyzed, and the post-hospitalization evolution of the disease assessed through a follow-up questionnaire. A rigorous logistic lasso regression model was applied to select significant predictors from a list of 37 patient characteristics potentially predictive of having chronic symptoms. Missing data were handled by complete case analysis, and a survival analysis was implemented. All models used standardized variables, and multiple comparisons in the survival analyses were handled by Bonferroni correction. Among all studied variables, five significant predictors of having symptoms lasting ≥3 months were identified: age, tobacco consumption, acute bradycardia, laboratory measures of urea, and neutrophils. This exploratory, hypothesis-generating study contributes to the development of ciguatera epidemiology by narrowing the list from 37 possible predictors to a list of five predictors that seem worth further investigation as candidate risk factors in more targeted studies of ciguatera symptom duration.

Background:Enthesitis is an important feature of ankylosing spondylitis (AS) and structural and inflammatory entheseal lesions (EL) are frequently present on ultrasound. Plain radiographs also provide good imaging of structural entheseal involvement1. Until now, little is known about the presence of structural EL at the hip and pelvic region and the association with patient characteristics in AS.Objectives:Our aim was to investigate the prevalence of radiographic EL at the hip and pelvic region in AS patients compared to age and sex matched control subjects and to explore the relation with AS patient characteristics.Methods:AS patients from the Groningen Leeuwarden Axial SpA (GLAS) cohort, included between November 2004 and December 2010, with available anteroposterior (AP) pelvis radiographs at baseline were included. All patients fulfilled the modified New York criteria for AS. Additionally, 100 randomly selected AP pelvis radiographs from age and sex matched control subjects were obtained from the radiology department of the University Medical Center Groningen. The sacroiliac joints of all radiographs were blinded and radiographs were scored independently by two trained observers unaware of patient characteristics and treatment. The entheseal sites scored were: trochanter major, trochanter minor, os ischium, crista iliaca, both left and right side. The following 3 EL were scored: erosion/cortical irregularity, calcification and enthesophyte. Only lesions with absolute agreement between both observers were used for analyses. Radiographic spinal involvement was scored according to the modified Stoke AS Spine Score (mSASSS; range 0-72) and radiographic hip involvement according to the Bath AS Radiology Index (BASRI)-hip (range 0-4). Independent samples t test, Mann-Whitney U test, Chi-Square test, and Fisher Exact test were used to compare patient characteristics between patients with and without radiographic EL.Results:Of the 167 included AS patients, 117 (70%) were male, mean age was 43 ± 11 years, 133 (80%) were HLA-B27 positive and median symptom duration was 16 years (range 1-53). 127 (76%) AS patients and 58 (58%) controls showed EL, with 501 lesions in total of which 377 (75%) in AS patients. AS patients showed significantly more lesions than controls at all 5 locations. Os ischii showed the most lesions in both AS patients and controls (66% vs 53%, p<0.05). The most prevalent type of lesion in both groups was erosion/cortical irregularity (72% vs 51%, p<0.005). Enthesophytes were also more often observed in AS patients than in controls (31% vs 21%, p=0.07). Prevalence of calcifications was low in both groups and not significantly different (5% vs 2%, p=0.22). AS patients with EL were significantly older (mean 45.2 vs 35.1 yrs, p<0.005) and had longer symptom duration (median 18 vs 7.5 yrs, p<0.005) than patients without EL. Furthermore, patients with BMI >25 had significantly more often enthesophytes (42% vs 16%, p<0.05) than patients with a normal BMI. Additionally, AS patients with EL had significantly more often radiographic spinal damage than patients without EL with median mSASSS total score 8.7 vs 1.0 (p<0.005) and a trend toward significance for radiographic hip involvement (BASRI-hip score ≥2; p=0.06).Conclusion:Radiographic EL at hip and pelvic region are significantly more prevalent in AS patients than in age and sex matched controls. AS patients with EL were significantly older, had longer symptom duration and more spinal radiographic damage than patient without EL. Furthermore, BMI >25 was associated with a higher prevalence of enthesophytes. These new findings contribute to the knowledge of entheseal involvement in AS.References:[1]Voudouris et al.

Abstract Objectives Many patients with axial spondyloarthritis (axSpA) report persistent pain even when treated with anti-inflammatory agents. Our aim was to explore the presence of central sensitization (CS) and different types of illness perceptions in patients with axSpA, and to assess their associations with disease activity assessments. Methods Consecutive outpatients from the Groningen Leeuwarden Axial Spondyloarthritis (GLAS) cohort were included. Besides standardized assessments, patients filled out the Central Sensitization Inventory (CSI), Illness Perception Questionnaire (IPQ-R) and Pain Catastrophizing Scale (PCS). Univariable and multivariable linear regression analyses were used to investigate the association between questionnaire scores, patient characteristics and disease activity assessments ASDASCRP, BASDAI and CRP. Results We included 182 patients with a mean symptom duration of 21.6 years. Mean ASDASCRP was 2.1, mean BASDAI 3.9, and median CRP 2.9. Mean CSI score was 37.8 (scale 0–100) and 45% of patients scored ≥40, indicating a high probability of CS. CSI score, IPQ-R domain identity (number of symptoms the patient attributes to their illness), and IPQ-R domain treatment control (perceived treatment efficacy), and obesity were significantly and independently associated with both ASDASCRP and BASDAI, explaining a substantial proportion of variation in these disease activity scores (R2=0.35 and R2=0.47, respectively). Only obesity was also independently associated with CRP. Conclusion CS may be common in patients with long-term axSpA. CS, as well as specific illness perceptions and obesity were all independently associated with the widely used (partially) patient-reported disease activity assessments ASDASCRP and BASDAI. Treating physicians should take this into account in the follow-up and treatment of their patients.

Objective: Urinary tract iatrogenic trauma in abdominal or pelvic surgery may cause morbidity, mortality, or even medico-legal problems. The close embryonic, as well as anatomical relationship between urinary tract and genital organs, may be a predisposition for urinary tract trauma, especially ureter and bladder, in obstetrics and gynecology surgeries. This research aimed to evaluate the incidence of iatrogenic urinary tract trauma in obstetrics and gynecology surgeries. Material & Methods: This was a descriptive retrospective research. This research was conducted at Urology Division of Department of Surgery at H. Adam Malik General Hospital, Medan, from February to June 2016. Total sampling method was used. Data were collected from medical records of patients who had iatrogenic urinary tract trauma due to obstetrics and gynecology surgeries at H. Adam Malik General Hospital from January 2011 to December 2015. Parameters that were evaluated included patient characteristics, the type of obstetrics and gynecology procedure that was conducted, the type of urinary tract trauma, and the type of urologic procedure conducted. Data were registered and analyzed using statistical software SPSS version 22. Results: There were 25 patients with 28 incidences of iatrogenic urinary tract trauma, which consisted of 12 iatrogenic ureteral trauma and 16 iatrogenic bladder trauma, out of all patients who underwent obstetrics and gynecologic surgeries at H. Adam Malik General Hospital, Medan, from January 2011 to December 2016. The youngest patient was 19 years old, while the oldest patient was 78 years old. Mean age of patients was 46.48 years (SD ± 11.6). The age group with the most iatrogenic urinary tract trauma was between 26-45 years old, which consisted of 12 patients (48%). Gynecologic patients had the most iatrogenic urinary tract trauma, which was experienced by 23 patients (92%). The most common diagnosis was ovarian cancer. Hysterectomy was the most common procedure to cause iatrogenic urinary tract trauma, as was found in 23 patients (92%). All patients who were found with iatrogenic bladder trauma (15 patients; 60%) underwent bladder repair. Conclusion: Gynecologic procedure, especially hysterectomy, was the most common cause of iatrogenic urinary tract trauma. Bladder repair procedure was the most common procedure performed on patients who were found with iatrogenic urinary tract trauma.
