Die vorliegende Studie befasst sich mit dem Einfluss minimalinvasiver Zugangswege zur Mitralklappe auf den Herzrhythmus, den Erfolg einer perioperativ durchgeführten Ablation und die postoperative Notwendigkeit eines Herzschrittmachers. Mitralklappenvitien und deren herzchirurgische Versorgung sind in vielen Fällen mit präoperativ bestehendem oder postoperativ neu auftretendem Vorhofflimmern assoziiert. In den vergangenen Jahrzehnten haben sich neben der medikamentösen Therapie des Vorhofflimmerns und der durch die Mitralklappeninsuffizienz induzierten Herzinsuffizienz verschiedene minimalinvasive chirurgische Zugangswege zur Mitralklappe sowie Ablationsverfahren etabliert und einen kurativen Therapieansatz gebildet. Die Ablation im Zuge einer Mitralklappenchirurgie ist zu einem alltäglich durchgeführten Verfahren geworden. Neu auftretendes Vorhofflimmern im Rahmen der Mitralklappenchirurgie kann perioperativ begrenzt sein und konvertiert häufig innerhalb der ersten 6 Wochen spontan in den Sinusrhythmus. Es geht aber mit einer erhöhten Mortalität und Hospitalisierungszeit einher. Das neu auftretende Vorhofflimmern kann jedoch auch persistieren oder erst im Langzeitverlauf entstehen. Auch die Notwendigkeit eines Herzschrittmachers kann durch Mitralklappeneingriffe insbesondere mit additiver Ablation aufgrund der anatomischen Gegebenheiten erhöht sein. In unserer Arbeit ist von Interesse, ob sich die unten genannten Zugangswege im Hinblick auf das Neuauftreten von Vorhofflimmern im Langzeitverlauf, die Vorhofflimmerrezidivrate nach Ablation und die Schrittmacherrate mit und ohne durchgeführte Ablation unterscheiden. Die vorliegende Studie umfasst alle Mitralklappenoperationen, die zwischen 1998 und 2015 in der Klinik für Thorax-, Herz- und thorakale Gefäßchirurgie der Universitätsklinik Frankfurt am Main über die folgenden drei minimalinvasiven Zugangswege, durchgeführt wurden: Gruppe A bildeten 300 Patienten, die im genannten Zeitraum über eine anterolaterale Minithorakotomie mittels Chitwood-Klemme operiert wurden. Gruppe B bestand aus 687 Patienten, die über eine partielle obere Sternotomie mit superiorem transseptalem Zugang operiert wurden. Die 219 Patienten, bei denen eine partielle obere Sternotomie mit transcavalem Zugang angewandt wurde, bildeten Gruppe C. Die Auswertung erfolgte anhand von Patientenakten, internen und externen Untersuchungsbefunden und eines standardisierten Fragebogens im Follow-up. Es erfolgte eine zweite Auswertung nach Propensity Matching, um präoperative signifikante Unterschiede der Gruppen zu egalisieren. Im Ergebnis konnte in unserer Studie gezeigt werden, dass die atriale Inzision einen entscheidenden Einfluss auf den Ablationserfolg sowie auf die Schrittmacherinzidenz hat. Bekannt war dabei ein höheres Risiko für postoperatives Vorhofflimmern und Schrittmacherimplantationen aufgrund der anatomischen Gegebenheiten bei Gruppe B. Dass jedoch Gruppe C ein signifikant noch höheres Risiko für Schrittmacherimplantationen mit sich bringt, war überraschend und ist derzeit nicht in der Literatur beschrieben. In der multivariaten Analyse nach Matching waren Gruppe C, eine additive Ablation und das Alter signifikante unabhängige Prädiktoren für Schrittmacherimplantationen. In der logistischen Regression war Gruppe A ein unabhängiger Prädiktor für den Ablationserfolg zum Zeitpunkt der Entlassung. In der Langzeitbeobachtung trat Gruppe C an Stelle von Gruppe A, möglicherweise aufgrund der bei Gruppe A vorliegenden längsten Follow-up-Zeit. Wie schon in der vorliegenden Literatur diskutiert waren auch in unserer Auswertung hohes Alter und eine präoperative linksatriale Vergrößerung unabhängige Prädiktoren für den langfristigen Ablationserfolg. Es bedarf weiterer vergleichender Studien mit einheitlichen Follow-up-Zeiten, um die hier gezeigten Ergebnisse zu überprüfen. Insbesondere der transcavale Zugang, der sich im negativen Sinne auf die Zahl der Schrittmacherimplantationen auszuwirken scheint, gibt Anlass für weitere Untersuchungen.

ObjectiveWomen with Lynch syndrome have a risk up to 40–60% of developing endometrial cancer, which is higher than their risk of developing colorectal or ovarian cancer. To date, no data on the outcomes of patients with Lynch syndrome diagnosed with non-endometrioid endometrial cancer are available. The goal of this study was to evaluate the outcome of patients with Lynch syndrome diagnosed with non-endometrioid endometrial cancer.MethodsData from consecutive patients diagnosed with Lynch syndrome and with a histological diagnosis of non-endometrioid endometrial cancer were retrospectively collected in two referral institutes in Italy. A case–control comparison (applying a propensity matching algorithm) was performed in order to compare patients with proven Lynch syndrome and controls. Inclusion criteria were: (a) histologically-proven endometrial cancer; (b) detection of a germline pathogenic variant in one of the MMR genes; (c) adequate follow-up. Only carriers of pathogenic or likely pathogenic variants (ie, class 5 and 4 according to the InSiGHT classification) were included in the study. Survival outcomes were assessed using KaplanMeier and Cox models.ResultsOverall, 137 patients with Lynch syndrome were collected. Mean patient age was 49.2 (10.9) years. Genes involved in the Lynch syndrome included MLH1, MSH2, and MSH6 in 43%, 39%, and 18% of cases, respectively. The study population included 27 patients with non-endometrioid endometrial cancer, who were matched 1:2 with patients with sporadic cancers using a propensity matching algorithm. After a median follow-up of 134 months (range 1–295), 2 (7.4%) of the 27 patients developed recurrent disease (3 and 36 months) and subsequently died of disease (7 and 91 months). Patients diagnosed with Lynch syndrome experienced better disease-free survival (HR 7.86 (95% CI 1.79 to 34.5); p=0.006) and overall survival (HR 5.33 (95% CI 1.18 to 23.9); p=0.029) than controls.ConclusionsNon-endometrioid endometrial cancer occurring in patients with Lynch syndrome might be associated with improved oncologic outcomes compared with controls. Genetic/molecular profiling should be investigated in order to better understand the mechanism underlying the prognosis.

Abstract Background The effect of renal biopsy on the prognosis of elderly patients with chronic kidney disease remains unclear. Thus, in this study, we aimed to evaluate the relationship between renal biopsy and renal survival in this population.Methods In this multi-centre retrospective study, the baseline characteristics among three groups were balanced by propensity matching. All patients were divided into three groups according to age and renal biopsy. The clinicopathological features at biopsy and renal outcomes during the follow-up were collected and analysed. Renal outcomes were defined as estimated glomerular filtration rate < 15 mL/min/1.73 m2, dialysis, renal transplantation, or death. The prognostic effects of renal biopsy were evaluated using Cox regression models. Results A total of 1313 patients were identified. After propensity matching, 390 patients were selected and divided into three groups. After a total follow-up period of 55 months, 20 (13.3%) patients (47.6% group 1 vs 7.41% group 2 vs 39.1% group 3) reached renal outcomes. No significant differences were found in renal outcomes among aged patients whether they underwent renal biopsy or not. Cox regression analysis revealed risk factors in aged patients including low albumin and high levels of proteinuria and serum creatinine (P < 0.05). Platelet count was significant only in aged patients who underwent renal biopsy (hazard ratio: 0.642, P < 0.05). Conclusion In conclusion, renal biopsy in the elderly has not shown benefits in terms of renal survival, conservative treatment appears to be a viable therapeutic option in the management of those people.

Study Design: Retrospective cohort study. Objectives: Violation of the posterior soft tissues is believed to contribute to the development of proximal junctional kyphosis (PJK). Biomechanical and clinical studies suggest that augmentation of the posterior ligamentous structures (PLS) may help prevent PJK. The purpose of this study was to evaluate the effect of PLS augmentation on the rate of PJK at 1 year. Methods: A retrospective single-surgeon cohort study was performed of 108 adult spinal deformity patients who underwent 5 level fusions to the pelvis. Patients were divided into 2 groups: PLS+ patients had reconstruction of the PLS between upper instrumented vertebrae +1 (UIV+1) and UIV−1 with a surgical nylon tape while PLS− patients did not. Demographics, surgical data, and sagittal alignment parameters were compared between the cohorts. The primary outcome of interest was the development of PJK at final follow-up. A subgroup propensity match and logistic regression model were utilized to control for differences in the cohorts. Results: A total of 108 patients met final criteria, 31 patients (28.7%) were PLS+. There were no differences with regard to preoperative or final sagittal alignment parameters, number of levels fused, rates of 3-column osteotomies, and body mass index ( P > .05), though the PLS+ cohort was older and had larger initial sagittal corrections ( P < .05). The rates of PJK for PLS+ (27.3%) and PLS− (28.6%) were similar ( P = .827). After controlling for sagittal correction via propensity matching, PLS+ had no impact on PJK (29% vs 38.7%, P = .367). In our multivariate analysis, only increased sagittal malalignment and failure to restore sagittal balance were retained as significant predictors of PJK. Conclusion: Even after controlling for extent of correction and preoperative sagittal alignment, PLS reinforcement at UIV+1 using a hand-tensioned nylon tape does not reduce the incidence of PJK at 1 year.

Background and Aim: We compared 22-year composites of valve-related reoperation, morbidity, and mortality following mitral mechanical and bioprostheses in young rheumatics aged <45years. Methods: Retrospective comparative analysis of valve-related reoperations and survival data were performed from 466 consecutive propensity matched patients undergoing either bioprosthetic MVR (Group I, n=233) or mechanical MVR (Group II, n=233) between 1998 and 2019. Results: The median age was 33 (IQR: 27-40) and 34 (IQR: 28-39) years for Group I and II respectively. The mean follow-up was 3278.9 patient-years in the biological arm and 3384.4 patient-years in mechanical arm. Bioprosthetic arm exhibited lesser cumulative mortality (4.5% vs 9.9%, SMD= -0.04, p=0.65). Hazard regression for mortality included (HR, 95% CI) preoperative congestive heart failure (CHF) 11.44 (8.44, 624.9), p<0.0001; renal failure 19.51 (8.04, 47.35), p<0.0001; previous operation 6.84 (2.48, 18.84), p<0.0001; atrial fibrillation (AF) 7.64 (1.02, 57.13), p=0.006; LA clot 61.94 (8.28, 463.08), p<0.0001; giant LA >65 mm 7.87 (2.62, 23.56), p<0.0001; poor left ventricular (LV) function 0.94 (0.92, 0.97), p<0.0001; and prolonged aortic clamp time 1.07 (1.04, 1.11), p<0.0001). Propensity matching did not exhibit any difference in reoperations between bioprostheses and mechanical prostheses (18.8% vs 13.3%, SMD= -0.152, p=0.1). At a median follow-up of 136 (IQR: 76-197) months, actuarial survival was 90.32%±0.02% (p=0.09) and there was no difference between the groups (p=0.09). Conclusions: Bioprostheses are an acceptable alternative to mechanical prostheses in young rheumatics aged <45 years unwilling for mechanical valve, redo surgeries, life-long anticoagulation, and those desirous of pregnancy.

Abstract Purpose The small bites (SB) technique for closure of elective midline laparotomies (EMLs) and a prophylactic mesh (PM) in high-risk patients are suggested by the guidelines to prevent incisional hernias (IHs) and fascial dehiscence (FD). Our aim was to implement a protocol combining both the techniques and to analyze its outcomes. Methods Prospective data of all EMLs were collected for 2 years. Results were analyzed at 1 month and during follow-up. The incidence of HI and FD was compared by groups (M = Mesh vs. S = suture) and by subgroups depending on using SB. Results A lower number of FD appeared in the M group (OR 0.0692; 95% CI 0.008–0.56; P = 0.01) in 197 operations. After a mean follow-up of 29.23 months (N = 163; min. 6 months), with a lower frequency of IH in M group (OR 0.769; 95% CI 0.65–0.91; P < 0.0001). (33) The observed differences persisted after a propensity matching score: FD (OR 0.355; 95% CI 0.255–0.494; P < 0.0001) and IH (OR 0.394; 95% CI 0.24–0.61; P < 0.0001). On comparing suturing techniques by subgroups, both mesh subgroups had better outcomes. PM was the main factor related to the reduction of IH (HR 11.794; 95% CI 4.29–32.39; P < 0.0001). Conclusion Following the protocol using PM and SB showed a lower rate of FD and HI. A PM is safe and effective for the prevention of both HI and FD after MLE, regardless of the closure technique used.

221 Background: We sought to compare two common salvage strategies for radio-recurrent prostate cancer: androgen deprivation therapy (ADT: PR7 RCT NCT00003653) or local salvage ablation using cryotherapy (CRYO: single institution study Williams, Eur Urol. 2011;60(3):405). Methods: Pre-salvage therapy prognostic variables common to the two datasets (Gleason score at initial treatment, time from original RT, use of ADT at time of original RT, PSA at time of salvage, patient age) were used for propensity matching between patients from previously published ADT (1) and CRYO (2) datasets. Progression free survival (PFS, defined as time from initial treatment to development of castrate resistance or death); Disease Specific Survival (DSS, defined as time from salvage to prostate cancer related death) and Overall Survival (OS, defined as time from salvage to death from any cause) were compared between the propensity matched cohorts using Log-Rank and Cox PH regression statistics. Raw linear propensity scores included in the PH model to account for residual variability. A planned subset analysis examined the effect of neoadjuvant ADT among the CRYO cohort (no CRYO patients had adjuvant ADT). Results: Overall, 1119/1386 (ADT) and 172/187 (CRYO) patients were included in the propensity matched analysis. Median follow up was 6.7 yrs (ADT) and 18.7 yrs (CRYO). Median PFS (95% CI) was 10.7 yrs (9.5, 12.3) for CRYO vs. 7.0 yrs (6.1, 10.0) for ADT (HR 0.63 (0.44, 0.89), p = 0.009). Median OS was also longer for CRYO vs. ADT: 12.3 (11.0, 13.8) vs. 10.2 (9.4, not reached) yrs (HR 0.69; p = 0.02). 10 year DSS event rate was 16.5% CRYO vs. 18.5% ADT but was not statistically different. Neoadjuvant ADT did not affect outcomes in CRYO. Conclusions: A 3-year PFS and 2-year OS benefit was noted for the CRYO vs. ADT cohorts while no difference was noted in DSS. Potential explanations include residual bias not corrected for in the propensity scoring, variable follow-up duration, adverse effects from differing cumulative exposure to ADT or a combination of these factors. Prospective comparisons are required to control for these potential biases and compare other important outcomes such as side effects and quality of life.

OBJECTIVE Circumferential minimally invasive spine surgery (cMIS) for adult scoliosis has become more advanced and powerful, but direct comparison with traditional open correction using prospectively collected data is limited. The authors performed a retrospective review of prospectively collected, multicenter adult spinal deformity data. The authors directly compared cMIS for adult scoliosis with open correction in propensity-matched cohorts using health-related quality-of-life (HRQOL) measures and surgical parameters. METHODS Data from a prospective, multicenter adult spinal deformity database were retrospectively reviewed. Inclusion criteria were age > 18 years, minimum 1-year follow-up, and one of the following characteristics: pelvic tilt (PT) > 25°, pelvic incidence minus lumbar lordosis (PI-LL) > 10°, Cobb angle > 20°, or sagittal vertical axis (SVA) > 5 cm. Patients were categorized as undergoing cMIS (percutaneous screws with minimally invasive anterior interbody fusion) or open correction (traditional open deformity correction). Propensity matching was used to create two equal groups and to control for age, BMI, preoperative PI-LL, pelvic incidence (PI), T1 pelvic angle (T1PA), SVA, PT, and number of posterior levels fused. RESULTS A total of 154 patients (77 underwent open procedures and 77 underwent cMIS) were included after matching for age, BMI, PI-LL (mean 15° vs 17°, respectively), PI (54° vs 54°), T1PA (21° vs 22°), and mean number of levels fused (6.3 vs 6). Patients who underwent three-column osteotomy were excluded. Follow-up was 1 year for all patients. Postoperative Oswestry Disability Index (ODI) (p = 0.50), Scoliosis Research Society–total (p = 0.45), and EQ-5D (p = 0.33) scores were not different between cMIS and open patients. Maximum Cobb angles were similar for open and cMIS patients at baseline (25.9° vs 26.3°, p = 0.85) and at 1 year postoperation (15.0° vs 17.5°, p = 0.17). In total, 58.3% of open patients and 64.4% of cMIS patients (p = 0.31) reached the minimal clinically important difference (MCID) in ODI at 1 year. At 1 year, no differences were observed in terms of PI-LL (p = 0.71), SVA (p = 0.46), PT (p = 0.9), or Cobb angle (p = 0.20). Open patients had greater estimated blood loss compared with cMIS patients (1.36 L vs 0.524 L, p < 0.05) and fewer levels of interbody fusion (1.87 vs 3.46, p < 0.05), but shorter operative times (356 minutes vs 452 minutes, p = 0.003). Revision surgery rates between the two cohorts were similar (p = 0.97). CONCLUSIONS When cMIS was compared with open adult scoliosis correction with propensity matching, HRQOL improvement, spinopelvic parameters, revision surgery rates, and proportions of patients who reached MCID were similar between cohorts. However, well-selected cMIS patients had less blood loss, comparable results, and longer operative times in comparison with open patients.

AbstractKatharina Pistor’s book The code of capital – how the law creates wealth and inequality (Pistor, K. (2019). The code of capital – How the law creates wealth and inequality. Princeton: Princeton University Press) is an original and insightful intervention in the quest to understand both the rising inequality of the last 40 years, as well as the inner dynamics of capitalism, a social formation that has ruled in western societies for about 200 years now. Pistor shares many of the convictions of the publications in the journal Accounting, Economics and Law, such as the dangers to democracy inherent in the corporate form (Robé, J. P. (2011). The legal structure of the firm. Accounting, Economics and Law, 1(1). https://doi.org/10.2202/2152-2820.1001; Strasser, K., & Blumberg, P. (2011). Legal form and economic substance of enterprise groups: Implications for legal policy. Accounting, Economics and Law, 1(1). https://doi.org/10.2202/2152-2820.1000), the fact that firms and corporate form need to be distinguished (Y. Biondi, A. Canziani, & T. Kirat (Eds), (2007). The firm as an entity: Implications for economics, accounting and law. New York and London: Routledge) and that shareholders do not own corporations, but just their shares, it is only appropriate to discuss and present it to the wider audience of the journal, pointing to its fundamental insights and potential for follow-up research. The title of the book and its set-up evoke both Luhmann’s system theory with its penchant for binary code as well as Marx’s capital (Marx, K. (1955[1867]). Das Kapital. Berlin: Dietz Verlag, Vol. 1). Combining the coding of social systems and their relentless dynamic in innovating and generating new forms by recursively referring to established elements (Luhmann, N. (1984). Soziale Systeme. Frankfurt am Main: Suhrkamp Verlag; Luhmann, N. (1995). Das Recht der Gesellschaft. Frankfurt am Main: Suhrkamp Verlag) with Marx’s focus on the structuring effects capital has on society is making this a very inspiring book, which at the same time evokes many follow-up questions.

ObjectiveBioprosthetic valves are being used with increased frequency for valve replacement, with controversy regarding risk:benefit ratio compared with mechanical valves in younger patients. However, prior studies have been too small to provide comparative estimates of less common but serious adverse events such as infective endocarditis. We aimed to compare the incidence of infective endocarditis between bioprosthetic valves and mechanical valves.MethodsWe searched PubMed, Cochrane, EMBASE, Scopus and Web of Science from inception to April 2018 for studies comparing left-sided aortic and mitral bioprosthetic to mechanical valves for randomised trials or observational studies with propensity matching. We used random-effects model for our meta-analysis. Our primary outcome of interest was the rate of infective endocarditis at follow-up.Results13 comparison groups with 43 941 patients were included. Mean age was 59±7 years with a mean follow-up of 10.4±5.0 years. Patients with bioprosthetic valves had a higher risk of infective endocarditis compared with patients receiving mechanical valves (OR 1.59, 95% CI 1.35 to 1.88, p<0.001) with an absolute risk reduction of 9 per 1000 (95% CI 6 to 14). Heterogeneity within the included studies was low (I2=0%). Exclusion of the study with maximum weight did not change the results of the analysis (OR 1.57, 95% CI 1.14 to 2.17, p=0.006). A meta-regression of follow-up time on incidence of infective endocarditis was not statistically significant (p=0.788) indicating difference in follow-up times did not alter the pooled risk of infective endocarditis.ConclusionsBioprosthetic valves may be associated with a higher risk of infective endocarditis. These data should help guide the discussion when deciding between bioprosthetic and mechanical valves in individual patients.

Background:Hydroxychloroquine (HCQ) is a well-tolerated drug that contributes to downregulating the immune response against autoantigens and it has been used in several autoimmune diseases. In systemic sclerosis (SSc) it is used to treat inflammatory arthritis without proof of efficacy.Objectives:Our aim was to evaluate the use of HCQ and its impact on Health Assessment Questionnaire disability index (HAQ-DI) and the Cochin Hand Function Status (CHFS). in a large SSc cohort compared to a propensity matched group of SSc patients not using HCQ.Methods:SSc patients from the European Scleroderma Trials and Research (EUSTAR) data base treated with HCQ for at least 6 months were evaluated. Demographic and clinical data, concomitant drugs, duration of HCQ treatment and reasons for its discontinuation, HAQ-DI and CHFS (at least 2 evaluation) were recorded and were the outcome variables of interest. Statistical analysis was performed using propensity score matching for age, gender, disease duration, corticosteroids, immunosuppressives, vasoactive drugs, DMARDs in a 3:1 control:HCQ ratio. Standard descriptive statistics and Student’s t-test and Chi-square test were used to assess the propensity-matched groups.Results:1,636 of 17,805 SSc patients (9.2%) were treated with HCQ for at least 6 months; out of these 3% (50/1636). had at least a baseline and follow-up HAQ-DI evaluation, (and 44/1636 (2.7%) had at least a baseline and follow-up CHFS evaluation. Propensity matching assured that pts were matched for demographic variables such as gender (mean on HCQ vs no HCQ:femals:92.0 vs 85.3), age(49.8 vs 49.97yrs) disease duration(8.3 vs 9.1 yrs), limited disease(55.3 vs 62.6%) as well as background medications (P>0.1-0.9). We did not find any significant changes in HAQ or CHFS (difference in slope) over 365 days of treatment, comparing the HCQ-treated group to the non-HCQ treated patients (p=0.240 for both (Figure 1).Conclusion:Results from the EUSTAR registry showed that HCQ was used by 9.2% of SSc patients. HCQ use did not improve the HAQ or CHFS, comparing HCQ users to non-HCQ users.Disclosure of Interests:Silvia Bellando Randone: None declared, Holly Wilhalme: None declared, Cosimo Bruni: None declared, Elise Siegert: None declared, Paolo Airò: None declared, Rosaria Irace: None declared, Oliver Distler: None declared, Andrea Doria: None declared, Lidia P.
