Abstract
Background:The therapeutic aim for rheumatoid arthritis (RA) is to control disease activity and prevent radiographic progression. Various clinical scores are utilized to describe disease activity in RA patients. The DAS28 score can define states of low disease activity (LDA) and remission. Despite achieving LDA or remission, radiographic progression may nevertheless occur. However, the rates and frequency of this occurrence have not been analyzed in detail.Objectives:To describe the frequency and rate of radiographic progression in patients with persistent LDA or remission.Methods:Analysis of RA patients from the SCQM cohort. Persistent LDA or remission were defined as DAS 28 ≤3.2 or <2.6 respectively, at two subsequent follow up time points in the database. We included patients with at least two sets of radiographs within these intervals of LDA and/or remission. Radiographic progression was measured with the Ratingen-score (range 0-190), which describes joint erosions numerically. Repair was defined as an improvement in the Ratingen score >5 points/year and progression as >2 or >5 points change in the Ratingen score within one year.Results:Among 10’141 RA patients, 4’342 episodes of remission occurred in 3’927 patients with 1’776 sets of X rays available within these episodes. Similarly, 8’136 episodes of LDA in 6’765 patients and 2’358 sets of X rays were present within these intervals. For patients in LDA or remission, rates of repair were 5.5% and 4.8%, respectively, while for radiographic progression >5 points in the Ratingen score/year were 10.3% in both groups and for >2 points change of Ratingen score/year were 27.7 and 25.4%, respectively).No differences for demographic factors or measures of disease activity, rheumatoid factor or ACPA were found comparing patients with radiographic progression or non-progression despite LDA or remission at the beginning of the episode of LDA and/or remission.Interestingly, 42.9% of patients in LDA with progression of >5 points in the Ratingen score/year were current smokers vs 29.4% among the non-progressors (X2 = 6.55, p = 0.01). This significant difference vanished when the cut-off for radiographic progression was set at >2 points yearly change in Ratingen score or in patients in remission.Conclusion:Radiographic progression despite LDA or remission are more frequent than expected. No differences in radiographic progression were found comparing LDA and remission suggesting that the goal of LDA is appropriate. Smoking seems to be an independent risk factor for radiographic progression despite LDA. Why the effect of smoking could was not demonstrated in patients in remission, remains unclear.Disclosure of Interests:Lena Brandt: None declared, Hendrik Schulze-Koops: None declared, Thomas Hügle Consultant of: GSK, Abbvie, Pfizer, Jansen, Novartis, Eli Lilly., Michael J.

Abstract
Background:Janus Kinase Inhibitors (JAKi) have recently been approved for the treatment of rheumatoid arthritis (RA) over the last years. JAKi differ in their specificity for the different JAK family members (JAK1, JAK2, JAK3 and TYK2). All three JAKis that are currently approved in Switzerland seem to have comparable efficacy on different disease stages of RA. Whether a JAKi can be effective after discontinuation of another JAKi is one of the open questions of interest according to the EULAR RA guidelines [1].Objectives:To study the effectiveness of baricitinib in patients with RA after discontinuation of tofacitinib.Methods:Longitudinal, retrospective chart review conducted between October 2019 and December 2020 of patients with RA at two Swiss centers (Kantonsspital Aarau and Inselspital Bern). Disease activity was assessed by DAS 28.Results:12 patients (1 male, 11 female) were treated with 4mg baricitinib/d after tofacitinib was discontinued. Mean age of the patients was 61 years, disease duration 140 months. Patients were previously treated with at least two conventional synthetic DMARDs and 75% with at least one biological DMARD. 58% of patients were positive for ACPA, 42% for rheumatoid factor. 50% of the patients suffered from erosive disease. Tofacitinib was stopped in 92% of the patients because of an insufficient response after a mean of 25.8 months. Moderate EULAR response was achieved in 83.3% of the patients after an average of 8 months treatment with baricitinib, and good EULAR response in 58.3% after an average of 10 months. There were no serious adverse events, neoplasms, opportunistic or serious infections during follow-up.Conclusion:The first retrospective analysis of real-world data of baricitinib following tofacitinib shows that there is a good clinical response in 70% of cases. Although limited by the number of patients this study therefore supports the notion that baricitinib after discontinuation of tofacitinib in RA patients may be an effective therapeutic option.References:[1]Smolen JS, Landewé RBM, Bijlsma JWJ, et al.

Abstract
With widespread use of endoscopy, ampullary adenomas are more frequently identified, many of which are not amenable to endoscopic resection. Pancreatoduodenctomy is curative for these lesions but carries high morbidity. The purpose of this study was to determine the safety and efficacy of transduodenal ampullectomy for these lesions. Data were collected on 32 patients who underwent transduodenal ampullectomy from 2002 to 2010. The median age of patients was 64 years. Adenomas were found because of abdominal pain in 34 per cent, jaundice in 22 per cent, and incidentally on endoscopic screening in 16 per cent and on computed tomography scan of the abdomen in 9 per cent. All patients had a preoperative diagnosis of premalignant disease; 6 per cent required intraoperative conversion to pancreaticoduodenectomy after frozen section evaluation documented carcinoma. Of ampullectomies, 97 per cent had clear margins. Follow-up was 28 months. Four (13%) patients developed recurrent disease at 4 years, 2 years, 1.5 years, and 4 months; all had clear margins at ampullectomy and underwent subsequent pancreaticoduodenectomy with invasive malignancy in a single patient. After preoperative biopsy documenting premalignant disease, malignancy at ampullectomy is unusual. Recurrence is uncommon but occurs even with clear margins necessitating diligent follow-up; even with diligent follow-up, recurrence can be malignant.

Abstract
Initial outcomes suggest laparoendoscopic single-site (LESS) Heller myotomy with anterior fundoplication provides safe, efficacious, and cosmetically superior outcomes relative to conventional laparoscopy. This study was undertaken to define the learning curve of LESS Heller myotomy with anterior fundoplication. One hundred patients underwent LESS Heller myotomy with anterior fundoplication. Symptom frequency and severity were scored using a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). Symptom resolution, additional trocars, and complications were compared among patient quartiles. Median data are presented. Preoperative frequency/severity scores were: dysphagia = 10/8 and regurgitation = 8/7. Additional trocars were placed in 12 patients (10%), of whom all were in the first two quartiles. Esophagotomy/gastrotomy occurred in three patients. Postoperative complications occurred in 9 per cent. No conversions to “open” operations occurred. Length of stay was 1 day. Postoperative frequency/severity scores were: dysphagia = 2/0 and regurgitation = 0/0; scores were less than before myotomy ( P < 0.001). There were no apparent scars, except where additional trocars were placed. LESS Heller myotomy with anterior fundoplication well palliates symptoms of achalasia with no apparent scar. Placement of additional trocars only occurred early in the experience. For surgeons proficient with the conventional laparoscopic approach, the learning curve of LESS Heller myotomy with anterior fundoplication is short and safe, because proficiency is quickly attained.

Abstract
Bio-medical waste has a higher potential of infection and injury to the healthcare worker, patient and the surrounding community. Awareness programmes on their proper handling and management to healthcare workers can prevent the spread of infectious diseases and epidemics. This study was conducted in a tertiary care hospital to assess the impact of training, audits and education/implementations from 2009 to 2012 on awareness and practice of biomedical waste segregation. Our study reveals focused training, strict supervision, daily surveillance, audits inspections, involvement of hospital administrators and regular appraisals are essential to optimise the segregation of biomedical waste.

Abstract
OBJECTIVE To assess the ability of preoperative computed tomography (CT) scan of the abdomen/pelvis and serum CA-125 to predict suboptimal (>1cm residual disease) primary cytoreduction in advanced ovarian, fallopian tube, and peritoneal cancer. METHODS This was a prospective, non-randomized, multicenter trial of patients who underwent primary cytoreduction for stage III-IV ovarian, fallopian tube, and peritoneal cancer. A CT scan of the abdomen/pelvis and serum CA-125 were obtained within 35 and 14 days before surgery, respectively. Four clinical and 20 radiologic criteria were assessed. RESULTS From 7/2001 to 12/2012, 669 patients were enrolled; 350 met eligibility criteria. The optimal debulking rate was 75%. On multivariate analysis, three clinical and six radiologic criteria were significantly associated with suboptimal debulking: age ≥ 60 years (p=0.01); CA-125 ≥ 500 U/mL (p<0.001); ASA 3-4 (p<0.001); suprarenal retroperitoneal lymph nodes >1cm (p<0.001); diffuse small bowel adhesions/thickening (p<0.001); and lesions >1cm in the small bowel mesentery (p=0.03), root of the superior mesenteric artery (p=0.003), perisplenic area (p<0.001), and lesser sac (p<0.001). A 'predictive value score' was assigned for each criterion, and the suboptimal debulking rates of patients who had a total score of 0, 1-2, 3-4, 5-6, 7-8, and ≥ 9 were 5%, 10%, 17%, 34%, 52%, and 74%, respectively. A prognostic model combining these nine factors had a predictive accuracy of 0.758. CONCLUSIONS We identified nine criteria associated with suboptimal cytoreduction, and developed a predictive model in which the suboptimal rate was directly proportional to a predictive value score. These results may be helpful in pretreatment patient assessment.

Abstract
The learning curve for laparoendoscopic single-site (LESS) surgery was found to be definable, short, and safe. Background and Objectives: This study of laparoendoscopic single-site (LESS) fundoplication for gastroesophageal reflux disease was undertaken to determine the “learning curve” for implementing LESS fundoplication. Methods: One hundred patients, 38% men, with a median age of 61 years and median body mass index of 26 kg/m2, underwent LESS fundoplications. The operative times, placement of additional trocars, conversions to “open” operations, and complications were compared among patient quartiles to establish a learning curve. Median data are reported. Results: The median operative times and complications did not differ among 25-patient cohorts. Additional trocars were placed in 27% of patients, 67% of whom were in the first 25-patient cohort. Patients undergoing LESS fundoplication had a dramatic relief in the frequency and severity of all symptoms of reflux across all cohorts equally (P < .05), particularly for heartburn and regurgitation, without causing dysphagia. Conclusion: LESS fundoplication ameliorates symptoms of gastroesophageal reflux disease without apparent scarring. Notably, few operations required additional trocars after the first 25-patient cohort. Patient selection became more inclusive (eg, more “redo” fundoplications) with increasing experience, whereas operative times and complications remained relatively unchanged. The learning curve of LESS fundoplication is definable, short, and safe. We believe that patients will seek LESS fundoplication because of the efficacy and superior cosmetic outcomes; surgeons will need to meet this demand.

Postoperative frequency/severity scores were: dysphagia = 2/0 and regurgitation = 0/0; scores were less than before myotomy (P < 0.001). There were no apparent scars, except where additional trocars were placed. LESS Heller myotomy with anterior fundoplication well palliates symptoms of achalasia with no apparent scar. Placement of additional trocars only occurred early in the experience. For surgeons proficient with the conventional laparoscopic approach, the learning curve of LESS Heller myotomy with anterior fundoplication is short and safe, because proficiency is quickly attained.

Abstract
Initial outcomes suggest laparoendoscopic single-site (LESS) Heller myotomy with anterior fundoplication provides safe, efficacious, and cosmetically superior outcomes relative to conventional laparoscopy. This study was undertaken to define the learning curve of LESS Heller myotomy with anterior fundoplication. One hundred patients underwent LESS Heller myotomy with anterior fundoplication. Symptom frequency and severity were scored using a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). Symptom resolution, additional trocars, and complications were compared among patient quartiles. Median data are presented. Preoperative frequency/severity scores were: dysphagia = 10/8 and regurgitation = 8/7. Additional trocars were placed in 12 patients (10%), of whom all were in the first two quartiles. Esophagotomy/gastrotomy occurred in three patients. Postoperative complications occurred in 9 per cent. No conversions to "open" operations occurred. Length of stay was 1 day. Postoperative frequency/severity scores were: dysphagia = 2/0 and regurgitation = 0/0; scores were less than before myotomy (P < 0.001). There were no apparent scars, except where additional trocars were placed. LESS Heller myotomy with anterior fundoplication well palliates symptoms of achalasia with no apparent scar. Placement of additional trocars only occurred early in the experience.

Abstract
There have been great advances in laparoscopic surgery for gastroesophageal reflux disease (GERD), including laparoendoscopic single-site (LESS) surgery. This study details our experience with over 1000 patients undergoing fundoplication for GERD and the journey therein. A total of 1078 patients have been prospectively followed after fundoplication. Patients scored the frequency/severity of symptoms using a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). We compared the outcomes of the first and last 100 patients. Median data are reported. Of 1078 patients, 943 underwent conventional laparoscopic fundoplication and 135, most recently, underwent LESS fundoplication. Before fundoplication, patients noted frequent/severe symptoms (e.g., heartburn: frequency = 8, severity = 8). Fundoplication ameliorated frequency/severity of symptoms (e.g., heartburn: frequency = 2, severity = 0; less than preoperatively, P < 0.05). Relative to our first 100 patients, patients after LESS surgery had similar symptom control (e.g., heartburn: frequency = eight to two vs eight to zero, severity = eight to one vs six to one) but had shorter hospital stays (2 vs 1 day, P < 0.05) and had no apparent scars. Laparoscopic fundoplication provides durable and efficacious treatment for GERD; long-term symptom resolution and patient satisfaction support its continued application. The advent of LESS surgery advances surgeons’ abilities to provide safe and salutary care while promoting cosmesis.

Abstract
Readmissions after operations are a burden. This study was undertaken to determine factors predicting readmissions after pancreaticoduodenectomy. Since 1991, patients undergoing pancreaticoduodenectomy have been prospectively followed. Nineteen per cent of 913 patients were readmitted within 30 days after discharge from pancreaticoduodenectomy. The causes for read-missions were reviewed. Median data are presented. All patients had preoperative comorbidities; most common were cardiovascular (26%), gastrointestinal (23%), or endocrine (15%). Twenty-nine per cent had extended pancreaticoduodenectomy, including major vascular resections. The most common reasons for readmission were: nausea/vomiting (26%), wound infection (15%), and abdominal pain (18%). Gender, body mass index, duration of operation, blood loss, length of stay, pathology, American Joint Committee on Cancer™ stage, and margin status did not predict readmission. Patients being readmitted were younger (65 vs 69 years, P < 0.001) and had more comorbidities ( P < 0.001). Readmission did not curtail long-term survival. Pancreaticoduodenectomy is a complex operation undertaken in patients with notable comorbidities. Readmissions occur frequently after pancreaticoduodenectomy and patients with more comorbidities are at particular risk. Readmissions are not generally the result of complications specific to pancreaticoduodenectomy, but seem more related to ill health, inaccessible nonhospital medical care, and poor expectations. Efforts must focus on patient expectations, intermediate care, home health care, and improving medical care after discharge.

Abstract
BACKGROUND This report details our experience with laparoendoscopic single site (LESS) fundoplication for GERD and provides a comparison to earlier contiguous patients undergoing conventional laparoscopic fundoplication. METHODS With institutional review board approval, symptoms before and after LESS fundoplications and conventional laparoscopic fundoplications were scored by patients. Outcomes after 130 consecutive LESS fundoplications were compared to 130 contiguous consecutive outcomes after conventional laparoscopic fundoplications. RESULTS Patients undergoing conventional laparoscopic vs. LESS fundoplication were very similar. There were no conversions to "open" operations and no notable complications with LESS fundoplication. Symptom reduction was broad and dramatic for patients undergoing LESS or conventional laparoscopic fundoplication; 96 % of patients who underwent LESS fundoplication scored their incision as ≥8 (1 = revolting to 10 = beautiful). CONCLUSIONS Relative to conventional laparoscopy, LESS surgery provides excellent resolution of symptoms without an apparent scar. In comparison to conventional laparoscopy, LESS fundoplication is as safe with similar symptom improvement and superior cosmesis.

Abstract
Millions of Americans are affected by gastroesophageal reflux disease (GERD) in many different ways. The magnitude of the problem of GERD was brought to light by the ambulatory pH test, the introduction of minimally invasive surgery, and the advent of the many medications that are effective in acid suppression. Patients with GERD suffer from various consequences associated with the disease. However, interventions beyond medical therapy, such as laparoscopic fundoplication, provide satisfactory outcomes and definitive relief of acid reflux.

Abstract
INTRODUCTION Polytetrafluoroethylene (PTFE)-covered transjugular intrahepatic portosystemic shunt (TIPS) stents purportedly provide superior patency. This study was undertaken to determine whether covered stents provide better long-term patency and outcomes after TIPSs. METHODS Patients with portal hypertension undergoing TIPS at a large teaching hospital from 2001 to 2010 were studied. Median data are presented. RESULTS Two hundred forty-six patients underwent TIPS; 70 received uncovered stents, and 176 received covered stents. Patients who received uncovered stents had more severely impaired liver function (41% were Child class C cirrhotics). The follow-up was longer with uncovered stents (48 vs 24 months, P < .01). Reinterventions for stenosis were undertaken in 33% with uncovered stents versus 19% with covered stents (P = .01). Shunt dysfunction occurred in 57% with uncovered stents versus 21% covered (P = .05). A deterioration of hepatic function occurred in 31% with uncovered stents versus 30% with covered (P = .32). Survival with uncovered stents was 31 months versus 33 months with covered stents (P = .55, Kaplan-Meier). CONCLUSIONS Covered stents may improve patency but do not mitigate postshunt hepatic dysfunction and do not improve survival.

Abstract
A systematic study of crystal lattice reorientation in early stages of recrystallization has been carried out to correlate the orientations of recrystallization nuclei with the deformation microtexture and with slip systems. Microstructure and texture of Al-1 wt.% Mn single crystals of unstable initial orientations of {112}111, {100}001 and {001}110 have been examined by high-resolution field-emission gun scanning electron microscope local orientation measurements. All single crystals were channel-die deformed at room temperature and then annealed for a short time. It was shown that often observed presence of the 112 directions as rotation axes in the formation of new nuclei orientation directly suggested a close link with the deformation process.

Abstract
Intuitively, more severe acid reflux causes more severe symptoms. This study was undertaken to correlate preoperative DeMeester scores with symptoms before and after laparoscopic Nissen fundoplication. Before fundoplication, all patients with gastroesophageal reflux disease underwent 24 to 48 hour pH testing. Before and after fundoplication, the frequency and severity of reflux symptoms were scored using a Likert scale. Four hundred and eighty-one patients underwent fundoplication and were followed for a mean of 32 months. The preoperative median DeMeester score was 41 (range 14.8 to 361.5). Before fundoplication, DeMeester scores correlated with severity of gastroesophageal reflux disease symptoms (Spearman regression analysis, P < 0.05 for all). Postoperatively, all symptom scores improved (Wilcoxon matched pairs test, P < 0.05 for all). After fundoplication, preoperative DeMeester scores did not correlate with the frequency or severity of symptoms. For patients with excessive acid reflux, reflux severity impacts the frequency and severity of symptoms before fundoplication. Laparoscopic Nissen fundoplication improves the frequency and severity of all reflux symptoms. The severity of preoperative reflux does not impact the frequency or severity of symptoms after fundoplication. Relief of excessive acid reflux, regardless of severity or degree (i.e., DeMeester scores), ameliorates symptoms of acid reflux thereby encouraging fundoplication, especially for patients with very abnormal DeMeester scores.

Abstract
BACKGROUND AND STUDY AIMS A major leak from a rectal anastomosis is an important surgical complication. Endoscopic transanal vacuum-assisted rectal drainage (ETVARD) is a new method for treating nonseptic major anastomotic leaks after extraperitoneal rectal anastomoses. PATIENTS AND METHODS Between January 2002 and March 2007 a total of 17 patients (mean age 61.2 years) who developed anastomotic leakage after resection of the rectum or rectosigmoid colon were prospectively evaluated. Their treatment began with endoscopic debridement of the leak/cavity; nylon sponges were then endoscopically fitted into the cavity. Continuous suction was applied via suction tubes inserted into the sponges. Repeat endoscopies and sponge exchanges, including further debridement were essential. RESULTS In 16/17 patients ETVARD was successful, relieving patients quickly from infectious symptoms and other complaints; one patient eventually required a Hartmann's procedure. Cavity sizes varied from 2 cm x 2 cm to 10 cm x 13 cm. The mean duration of drainage was 21.4 days, with a mean of 5.4 sponge exchanges and 10.7 endoscopies, and a mean total time to closure of the cavity of 53.1 days. The total time to closure of the cavity was directly dependent on the size of the cavity ( P< 0.015). Fifteen patients received additional intramural fibrin glue injections. In eight patients ETVARD was continued on an outpatient basis. There was no advantage demonstrated for patients with diverting loop ileostomies. Patients with anastomoses that were 6 cm or less from the anocutaneous line had considerably longer healing times. The healing time depended significantly on age ( P< 0.036). Follow-up endoscopies have shown only minor anastomotic changes in two patients. CONCLUSIONS ETVARD is a well-tolerated and effective therapeutic option for the treatment of major leaks after extraperitoneal rectal anastomoses. In most cases ETVARD obviates the need for additional surgery, in particular diverting loop ileostomy.

Abstract
AIMS Urogenital tract infection (UTI) due to bacteria is not only a common infection but also a complication during hospitalization. Therefore, the identification and quantification of bacteria in urine samples are routinely performed methods in microbiological laboratories. To differentiate between infection and contamination it is also important to quantify the leukocyte count. In this study, we suggest a screening procedure using the flow cytometer analyzer BACSYS-40i as tool for the diagnosis of UTI. MATERIAL AND METHODS Each urine sample was inoculated onto agar plates (MacConkey agar, sheep blood agar and enterococcosel agar (Bio Merieux, Nütingen, Germany)) within 4 hours after collection. After 24 up to 48 hours incubation at 37 degrees C, bacteria were quantified by evaluation of colony-forming units (CFU) according to the criteria given by the German recommendation [MIQ 1997]. Additionally, each sample was submitted to the BACSYS-40i analyzer. The technological principle is a fluorescence flow cytometer with a laser and a fluorescent dye to identify bacteria and leukocytes with high analytical sensitivity. RESULTS Coefficients of variation (CV) for examination of within-run reproducibility ranged from 1.7 - 9.0% for leukocytes and from 6.2 - 24.6% for bacteria. Linearity was found to be very good, with coefficients of determination of r = 0.9998 for leukocytes, and r = 0.9994 for bacteria. Carry-over was calculated and found to be extremely low, ranging up to 0.03% for leukocytes and up to 0.002% for bacteria. The correlation coefficient for leukocyte counting is 0.979, regression y = 1.0 x + 1.0. The number of bacteria determined with the BACSYS-40i (total cell count) is higher than the number determined by culture (viable cell count). If the cut-offs of the analyzer were fixed at > or = 10(6) and < 10(5) bacteria/microl for positive, respectively negative results, 39 out of 42 patients (93%) showing unambiguous predominant clinical signs of UTI and in addition growth of bacteria involved in UTI were recognized. Six samples were questionable. CONCLUSIONS Results obtained by the BACSYS-40i can be reported after a few minutes. Urine samples from all 57 patients with predominant clinical signs and in addition growth of bacteria isolated from urine and known as pathogens of UTI had positive results with the analyzer (100%) for elevated bacteria and leukocyte counts. Furthermore, all patients without symptoms for UTI were negative after analysis with the BACSYS-40i (44/44; 100%).

Abstract
The crystallography of recrystallization has been investigated in channel-die deformed pure aluminium bicrystals with {100}<011>/{110}<001> orientations. The microstructural and microtextural changes during the early stages of recrystallization were followed by systematic local orientation measurements using scanning and transmission electron microscopes. In particular, orientation mapping combined with in situ sample heating was used to investigate the formation and growth of new grains at very early stages of recrystallization. Grain boundary migration and 'consumption' of the as-deformed areas was always favoured along directions parallel to the traces of the {111} slip planes that had been most active during deformation.

Abstract
A method for analysing EPR-time profiles of transient radicals in solution with unresolved hyperfine structure is proposed. It is based on considering the magnetic field integral of the magnetization, i.e., the total EPR signal intensity, instead of single components of overlapping EPR transitions. For a radical system involving chemical kinetics, chemically induced electron polarization (CIDEP), and spin relaxation, an analytical solution is found for the evolution of the integral magnetization in the Laplace domain. The solution in the time domain is given for the case of negligible saturation, i.e., omega2(1)T1T2 << 1. The formulae presented are suitable to avoid equivocal multi-parameter fits when analysing the results of time-resolved continuous-wave EPR experiments for the observables, which characterize the chemical kinetics, CIDEP, and electron spin relaxation of radical systems.
