Abstract Funding Acknowledgements none Introduction The second-generation CB (CB2, Arctic Front Advance, Medtronic Inc., Minneapolis, USA) has demonstrated high procedural success rates, relatively short procedure times, high durability of PVI and convincing long-term clinical success rates. Nevertheless, data on the impact of different ablations protocols on durability after CB2 based PVI is limited. Purpose We aimed at comparing durability of pulmonary vein isolation (PVI) following three different ablation strategies utilizing the second-generation cryoballoon (CB2) in patients with recurrence of atrial fibrillation (AF) or atrial tachycardia (AT) undergoing repeat procedures. Methods In 192 patients a total of 751 PVs were identified. All PVs (751/751, 100%) were successfully isolated during index PVI. Thirty-one out of 192 (16%) patients were treated with a bonus-freeze protocol (group 1), 67/192 (35%) patients with a no bonus-freeze protocol (group 2), and 94/192 (49%) patients with a "time-to-effect"-guided ablation protocol without bonus freezes (group 3). Results Persistent PVI was documented in 419/751 (55.8%) PVs, and in 41/192 (21%) patients all PVs were persistently isolated. The number of patients with all PVs being persistently isolated was not significant between the groups (p = 0.594). The total rate of PV reconnection was not significantly different between the three groups (p = 0.134) and the comparison of individual PVs revealed also no differences for different ablation protocols (p-values for RSPV: 0.424, RIPV: 0.541, LSPV: 0.788, LIPV: 0.346, LCPV: 0.865). The procedure times were significantly reduced in non-bonus freeze ablation protocols and/or when applying individualized application times (group 1: 123.4 ± 31.5min, group 2: 112.9 ± 39.8 min, group 3:  86.67 ± 28.4 min, p <0.001). Conclusions A considerably high rate of persistent PVI was demonstrated in patients after index CB2-based PVI. No differences for durable PVI were detected for different ablation protocols. Therefore, individualized ablation protocols might be a beneficial ablation strategy during CB2-based PVI.

Outcomes are superior for pancreatic resection at high-volume centers. To assess the impact of focused high-volume multidisciplinary care, a quality index (QI) was used to review our experience. Data from 1996 to July 2012 were analyzed in three groups: 1) early (1996 to 2007); 2) transition (2008 to 2009); and 3) mature (2010 to July 2012). A total of 239 patients were included with a mean age of 63.4 years and the majority were white (65.7%). The number of patients with Charlson comorbidity index greater than 2 and age older than 80 years increased comparing Group 1 with latter groups. Volume increased over time: Group 1 (n = 93) 7.75/year, Group 2 (n = 51) 25.5/year, and Group 3 (n = 95) 39/year. Overall mortality was 5.9 per cent: Group 1, 4.3 per cent; Group 2, 11.5 per cent; and Group 3, 3.9 per cent ( P = 0.0454). The QI score incorporates documentation, chemotherapy, resection for Stage I/II, time to treatment, margins, lymph nodes, mortality, and surgical volume with a maximum possible score 10. The QI increased over time: 3 in Group 1; 4 in Group 2; and 6 in Group 3. An improvement was noted for the quality indicators: surgical resection ( P = 0.0125) and use of palliative and adjuvant therapy ( P = 0.0144 and < 0.0001). Implementation of a focused multidisciplinary pancreatic surgery program increases quality.

Abstract INTRODUCTION Children treated for CNS tumours experience a very high burden of adverse effects. Platinum-based chemotherapy and cranial radiotherapy can cause ototoxicity, which may be particularly problematic in patients who have impaired vision and cognition as a result of their tumour and associated treatment. This study assessed the prevalence of impaired hearing and vision and how this may impact upon education. METHODS 53 patients diagnosed with solid tumours in Edinburgh, UK between August 2013–2018 were included in the study. Patients were split into three groups according to treatment received: Group 1 – cisplatin-based chemotherapy and cranial radiotherapy; Group 2 - platinum-based chemotherapy, no cranial radiotherapy; Group 3 – benign brain tumours treated with surgery only. Data was collected retrospectively from patient notes. RESULTS Overall 69.5% of those treated with platinum-based chemotherapy experienced ototoxicity as assessed by Brock grading and 5.9% of patients had reduced visual acuity. Patients in Group 1 had the highest prevalence of both. 44.4% of patients in Group 1 needed increased educational support following treatment, either with extra support in the classroom or being unable to continue in mainstream school. 12.5% of Group 2 patients required such support and 31.3% in Group 3. CONCLUSIONS Children with CNS tumours frequently require support for future education but those treated with both platinum-based chemotherapy and cranial radiotherapy are at particular risk, which may be compounded by co-existent ototoxicity and visual impairment. It is essential to provide appropriate support for this patient cohort in order to maximise their educational potential.

Objective To determine the relationship between cartilage lesion etiology and clinical outcomes after second-generation autologous chondrocyte implantation (ACI) in the patellofemoral joint (PFJ) with a minimum of 2 years’ follow-up. Methods A retrospective review of all patients that underwent ACI in the PFJ by a single surgeon was performed. Seventy-two patients with a mean follow-up of 4.2 ± 2.0 years were enrolled in this study and were stratified into 3 groups based on the etiology of PFJ cartilage lesions: patellar dislocation (group 1; n = 23); nontraumatic lesions, including chondromalacia, osteochondritis dissecans, and degenerative defects (group 2; n = 28); and other posttraumatic lesions besides patellar dislocations (group 3; n = 21). Patient’s mean age was 29.6 ± 8.7 years. Patients in group 1 were significantly younger (25.4 ± 7.9 years) than group 2 (31.7 ± 9.6 years; P = 0.025) and group 3 (31.5 ± 6.6 years; P = 0.05). Body mass index averaged 26.2 ± 4.3 kg/m2, with a significant difference between group 1 (24.4 ± 3.2 kg/m2) and group 3 (28.7 ± 4.5 kg/m2; P = 0.005). A clinical comparison was established between groups based on patient-reported outcome measures (PROMs) and failure rates. Results Neither pre- nor postoperative PROMs differed between groups ( P > 0.05). No difference was seen in survivorship between groups (95.7% vs. 82.2% vs. 90.5%, P > 0.05). Conclusion Cartilage lesion etiology did not influence clinical outcome in this retrospective study after second generation ACI in the PFJ. Level of Evidence Level III, retrospective comparative study.

AbstractOestradiol, an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization-embryo transfer (IVF-ET) cycles. A supraphysiologic E2 level is inevitable during controlled ovarian hyper-stimulation (COH), and its effect on the outcome of IVF-ET is controversial. The aim of this retrospective study is to evaluate the association between elevated serum oestradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and neonatal birthweight after IVF-ET cycles. The data of 3659 infertile patients with fresh IVF-ET cycles were analysed retrospectively between August 2009 and February 2017 in First Hospital of Zhengzhou University. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels ≤ 1000 pg/mL, n = 230), group 2 (serum E2 levels between 1001 and 2000 pg/mL, n = 524), group 3 (serum E2 levels between 2001 and 3000 pg/mL, n = 783), group 4 (serum E2 levels between 3001 and 4000 pg/mL, n = 721), group 5 (serum E2 levels between 4001 and 5000 pg/mL, n = 548 ), and group 6 (serum E2 levels > 5000 pg/mL, n = 852). Univariate linear regression was used to evaluate the independent correlation between each factor and outcome index. Multiple logistic regression was used to adjust for confounding factors. The LBW rates were as follows: 3.0% (group 1), 2.9% (group 2), 1.9% (group 3), 2.9% (group 4), 2.9% (group 5), and 2.0% (group 6) (P = 0.629), respectively. There were no statistically significant differences in the incidences of neonatal LBW among the six groups. We did not detect an association between peak serum E2 level during ovarian stimulation and neonatal birthweight after IVF-ET. The results of this retrospective cohort study showed that serum E2 peak levels during ovarian stimulation were not associated with birth weight during IVF cycles. In addition, no association was found between higher E2 levels and increased LBW risk. Our observations suggest that the hyper-oestrogenic milieu during COS does not seem to have adverse effects on the birthweight of offspring after IVF. Although this study provides some reference, the obstetric-related factors were not included due to historical reasons. The impact of the high estrogen environment during COS on the birth weight of IVF offspring still needs future research.

Background:Systemic lupus erythematosus (SLE) is an autoimmune disease mainly affecting women of childbearing age. The interplay between genetic and environmental factors may contribute to disease pathogenesis1. At today, no robust data are available about the possible contribute of diet in SLE. Caffeine, one of the most widely consumed products in the world, seems to interact with multiple components of the immune system by acting as a non-specific phosphodiesterase inhibitor2.In vitrodose-dependent treatment with caffeine seems to down-regulate mRNA levels of key inflammation-related genes and similarly reduce levels of different pro-inflammatory cytokines3.Objectives:We evaluated the impact of caffeine consumption on SLE-related disease phenotype and activity, in terms of clinimetric assessment and cytokines levels.Methods:We performed a cross-sectional study, enrolling consecutive patients and reporting their clinical and laboratory data. Disease activity was assessed by SLE Disease Activity Index 2000 (SLEDAI-2k)4. Caffeine intake was evaluated by a 7-day food frequency questionnaire, including all the main sources of caffeine. As previously reported, patients were divided in four groups according to the daily caffeine intake: <29.1 mg/day (group 1), 29.2-153.7 mg/day (group 2), 153.8-376.5 mg/day (group 3) and >376.6 mg/day (group 4)5. At the end of questionnaire filling, blood samples were collected from each patient to assess cytokines levels. These were assessed by using a panel by Bio-Plex assays to measure the levels of IL-6, IL-10, IL-17, IL-27, IFN-γ, IFN-α and Blys.Results:We enrolled 89 SLE patients (F/M 87/2, median age 46 years, IQR 14; median disease duration 144 months, IQR 150). The median intake of caffeine was 195 mg/day (IQR 160.5). At the time of the enrollment, 8 patients (8.9%) referred a caffeine intake < 29.1 mg/day (group 1), 27 patients (30.3%) between 29.2 and 153.7 mg/day (group 2), 45 patients (51%) between 153.8 and 376.5 mg/day (group 3) and 9 patients (10.1%) >376.6 mg/day (group 4). A negative correlation between the levels of caffeine and disease activity, evaluated with SLEDAI-2K, was observed (p=0.01, r=-0.26). By comparing the four groups, a significant higher prevalence of lupus nephritis, neuropsychiatric involvement, haematological manifestations, hypocomplementemia and anti-dsDNA positivity was observed in patients with less intake of caffeine (figure 1 A-E). Furthermore, patients with less intake of caffeine showed a significant more frequent use of glucocorticoids [group 4: 22.2%,versusgroup 1 (50.0%, p=0.0001), group 2 (55.5%, p=0.0001), group 3 (40.0%, p=0.009)]. Moving on cytokines analysis, a negative correlation between daily caffeine consumption and serum level of IFNγ was found (p=0.03, r=-0.2) (figure 2A); furthermore, patients with more caffeine intake showed significant lower levels of IFNα (p=0.02, figure 2B), IL-17 (p=0.01, figure 2C) and IL-6 (p=0.003, figure 2D).Conclusion:This is the first report demonstrating the impact of caffeine on SLE disease activity status, as demonstrated by the inverse correlation between its intake and both SLEDAI-2k values and cytokines levels. Moreover, in our cohort, patients with less caffeine consumption seems to have a more severe disease phenotype, especially in terms of renal and neuropsychiatric involvement. Our results seem to suggest a possible immunoregulatory dose-dependent effect of caffeine, through the modulation of serum cytokine levels, as already suggested byin vitroanalysis.References:[1]Kaul et alNat.

Abstract Background Contact force catheter ablation is the gold standard for treatment of atrial fibrillation (AF). Local tissue impedance (LI) evaluation has been recently studied to evaluate lesion formation during radiofrequency ablation. Purpose Aim of the study was to assess the outcomes of an irrigated catether with LI alghorithm compared to contact force (CF)-sensing catheters in the treatment of symptomatic AF. Methods A prospective, single-center, nonrandomized study was conducted, to compare outcomes between CF-AF ablation (Group 1) and LI-AF ablation (Group 2). For Group 1 ablation was performed using the Carto 3© System with the SmartTouch SF catheter and, as ablation target, an ablation index value of 500 anterior and 400 posterior. For Group 2, ablation was performed using the Rhythmia™ System with novel ablation catheter with a dedicated algorithm (DirectSense) used to measure LI at the distal electrode of this catheter. An absolute impedance drop greater than 20Ω was used at each targeted. According to the Close Protocol, ablation included a point by point pulmonary vein isolation (PVI) with an Inter-lesion space ≤5 mm in both Groups. Procedural endpoint was PVI, with confirmed bidirectional block. Results A total of 116 patients were enrolled, 59 patients in Group 1 (CF) and 57 in Group 2 (LI), 65 (63%) with a paroxismal AF and 36 (37%) with a persistent AF. Baseline patients features were not different between groups (P=ns). LI-Group showed a comparable procedural time (180±89 vs 180±56, P=0.59) but with a longer fluoroscopy time (20±12 vs 13±9 min, P=0.002). Wide antral isolation was more often observed in CF-Group (95% vs 80%, P=0.022), while LI-Group 2 required frequently additional right or left carina ablation (28% vs 14%, P=0.013). The mean LI was 106±14Ω prior to ablation and 92.5±11Ω after ablation (mean LI drop of 13.5±8Ω) during a median RF time of 26 [19–34] sec for each ablation spot. No steam pops or complications during the procedures were reported. The acute procedural success was 100%, with all PVs successfully isolated in all study patients. Regarding safety, only minor vascular complications were observed (5%), without differences between groups (p=0.97). During follow up, 9-month freedom from atrial fibrillation/atrial flutter/atrial tachycardia recurrence was 86% in Group 1 and 75% in Group 2 (P=0.2). Conclusions An LI-guided PV ablation strategy seems to be safe and effective, with acute and mid-term outcomes comparable to the current contact force strategy. LI monitoring could be a promising complementary parameter to evaluate not only wall contact but also lesion formation during power delivery.

Background: The COVID-19 pandemic is challenging healthcare systems worldwide. This study examines geriatric patients with proximal femur fractures during the COVID-19 pandemic, shifts in secondary disease profile, the impact of the pandemic on hospitalization and further treatment. Methods: In a retrospective monocentric study, geriatric proximal femur fractures treated in the first six months of 2020 were analyzed and compared with the same period of 2019. Pre-traumatic status (living in a care home, under supervision of a legal guardian), type of trauma, accident mechanism, geriatric risk factors, associated comorbidities, time between hospitalization and surgery, inpatient time and post-operative further treatment of 2 groups of patients, aged 65-80 years (Group 1) and 80+ years (Group 2) were investigated. Results: The total number of patients decreased (70 in 2019 vs. 58 in 2020), mostly in Group 1 (25 vs. 16) while the numbers in Group 2 remained almost constant (45 vs. 42). The percentage of patients with pre-existing neurological conditions rose in 2020. This corresponded to an increase in patients under legal supervision (29.3%) and receiving pre-traumatic care in a nursing home (14.7%). Fractures were mostly caused by minor trauma in a home environment. In 2020, total number of inpatient days for Group 2 was lower compared to Group 1 (p = 0.008). Further care differed between the years: fewer Group 1 patients were discharged to geriatric therapy (69.6% vs. 25.0%), whereas in Group 2 the number of patients discharged to a nursing home increased. Conclusions: Falling by elderly patients is correlated to geriatric comorbidities, consequently there was no change in the case numbers in this age group. Strategic measures to avoid COVID-19 infection in hospital setting could include reducing the length of hospital stays by transferring elderly patients to a nursing home as soon as possible and discharging independent, mobile patients to return home.

Abstract Background Although regional techniques have been suggested more in order to provide postoperative analgesia in inguinal hernia repairs, the ideal method is still controversial. The aim of this study was to evaluate the effect of preemptive transversus abdominis plane (TAP) block, local anesthetic infiltration (LAI) and intravenous dexketoprofen (IVD) on postoperative pain in inguinal hernia repairs. Methods This prospective study included 120 patients with American Society of Anesthesiologists status 1-3 between 18-75 years of age who undergoing elective inguinal hernia surgery under spinal anesthesia. The patients were allocated into three groups: USG-guided TAP block (Group 1, n = 40), USG-guided LAI (Group 2, n = 40) and IVD (Group 3, n = 40) before surgical incision. The mean of tramadol consumption, number of patients in requiring rescue analgesics, duration of postoperative analgesia and complications were recorded for 24 hours postoperatively. VAS scores were evaluated at the 30 minute, 1, 2, 4, 8, 12, 16 and 24th hours. Results There was no significant difference between the postoperative mean tramadol consumption [Group 1: 22.5 mg; Group 2: 20 mg; Group 3: 27.5 (p 0.833)]. The number of patients requiring rescue analgesics was statistically similar (p 0.787). VAS scores at 30. min, 1, 2, 4, 8 and 12 hours were statistically lower in Group 1 than in the other groups (p 0.003, 007, 0013, 0049, 0015, 0021). VAS scores at 30. min and 2. h were lower in Group 1 than Group 2 (p 0.049, 0.037). İn addition, VAS scores at 30 min, 1, 2, 8 and 12 hours were lower in Group 1 than in Group 3 (p 0.003, 0.006, 0.021, 0.017, 0.016). VAS scores at all hours were statistically similar between Group 2 and Group 3. Conclusion This study demonsrated that preemptive transversus abdominis plane block, local anesthetic infiltration or iv dexketoprofen for postoperative analgesia in inguinal hernia repairs had similar effects on postoperative tramadol consumption and number of requiring rescue analgesic patients. However, TAP block provides lower VAS values and excellent analgesia in more patients in the first 24 hours postoperatively.

Due to the growing number of patients with age-related diseases, the aim of the study was to investigate in the changes of aging rate (AR) in patients with comorbid course of arterial hypertension (H), type 2 diabetes mellitus (T2DM) and subclinical hypothyroidism (SH) and to study the features of these changes depending on hormonal imbalance. 118 patients (63 women and 55 men, average age — 53.6±4.3 years) were divided into 3 groups: group 1 (n=37) with isolated H; group 2 (n=42) — with H and T2DM; group 3 (n=39) — with H, T2DM and SH. The investigation program included: measurement of anthropometric parameters (blood pressure, height, body weight (BW), body mass index (BMI)), carbohydrate and thyroid metabolism using standard methods, biological age (BA) by V.P. Voitenko et al. Statistical processing was performed using the Statistica for Windows 8.0 software package. When evaluating AR, physiological aging was found in 8 patients (21.6%) of group 1, in 4 (9.5%) patients of group 2 and 3 (7.7%) of patients in group 3. In the overwhelming majority of the examined patients, premature aging (PA) was noted, however, the acceleration of PA between patients of groups 2 and 3 was not differ significantly (p>0.05). The increase in AR in group 2 patients was accompanied by an increase in BA by 7.2 years, in 3 group patients — by 7.3 years compared with their chronological age. A correlation analysis revealed a positive relationship between BMI and coefficient of aging rate (CAR) (r=0.679; p<0.05); BMI and BA (r=0.562; p<0.05) and CAR and the TSH level (r=0.050; p=0.388) in the 3rd group. Thus, the presence of hypertension and comorbid endocrinopathies — T2DM and SH significantly increases the AR and when assessing the effect of endocrine disorders, the presence of T2DM is more important than SH.

Background: It is usual to face clinical complexity in piles patients. They usually present with variable number of pile masses and in different grades of progression. This led to the idea of offering concomitant single stage management in our hemorrhoid patients matching to our criteria. We conducted hospital based descriptive study among the patients coming to my clinical practice falling in grade-1-3.Methods: All the patients falling in grade-1-3 and matching to our criteria were included. The study was conducted   from January 2012 to December 2020. Place of study was basically at two centres: Karamdeep medical centre, Kanpur and Mayo health care, Mohali. Total number of patients were 581. Patients having grade-4 piles and with local co-morbidities were excluded from the study. Modalities of treatment used were sclerotherapy, band ligation and hemorrhoidectomy.Results: Patients managed were divided into four groups – group 1 included patients with piles in grade-1; group-2 included patients having piles in grade-1 and 2; group-3 included patients having piles in grade-1 and 3; and group-4 included patients having piles in grade-1, 2 and 3. Total 952 pile masses were treated in 581 patients. Sclerotherapy was required in 732 (77%) masses, banding in 99 (10.3%) masses and surgery in 122 (12.7%) masses.Conclusions: Concomitant treatment policy proved to be comprehensive way to tackle pile patients of grade-1-3. Mixed and matched method using surgical and non-surgical modalities in a single sitting proved to be beneficial. 86.4% cases were cured this way. Cost of the treatment was economical with lesser complications including local mutilation and better quality of life.
