Abstract
PURPOSE To present the results of the first multi-centre real-world validation of autoplanning for whole breast irradiation after breast-sparing surgery, encompassing high complexity cases (e.g. with a boost or regional lymph nodes) and a wide range of clinical practices. METHODS The 24 participating centers each included 10 IMRT/VMAT/Tomotherapy patients, previously treated with a manually generated plan ('manplan'). There were no restrictions regarding case complexity, planning aims, plan evaluation parameters and criteria, fractionation, treatment planning system or treatment machine/technique. In addition to dosimetric comparisons of autoplans with manplans, blinded plan scoring/ranking was conducted by a clinician from the treating center. Autoplanning was performed using a single configuration for all patients in all centres. Deliverability was verified through measurements at delivery units. RESULTS Target dosimetry showed comparability, while reductions in OAR dose parameters were 21.4 % for heart Dmean, 16.7 % for ipsilateral lung Dmean, and 101.9 %, 45.5 %, and 35.7 % for contralateral breast D0.03cc, D5% and Dmean, respectively (all p < 0.001). Among the 240 patients included, the clinicians preferred the autoplan for 119 patients, with manplans preferred for 96 cases (p = 0.01). Per centre there were on average 5.0 ± 2.9 (1SD) patients with a preferred autoplan (range [0-10]), compared to 4.0 ± 2.7 with a preferred manplan ([0,9]). No differences were observed regarding deliverability. CONCLUSION The automation significantly reduced the hands-on planning workload compared to manual planning, while also achieving an overall superiority. However, fine-tuning of the autoplanning configuration prior to clinical implementation may be necessary in some centres to enhance clinicians' satisfaction with the generated autoplans.

Abstract
We analyzed peripheral blood mononuclear cells (PBMCs) and serum inflammatory biomarkers in patients with mesial temporal lobe epilepsy (drug-resistant - DR, vs. drug-sensitive - DS). Patients with epilepsy showed higher levels of serum CCL2, CCL3, IL-8 and AOPP, and lower levels of FRAP and thiols compared to healthy controls (HC). Although none of the serum biomarkers distinguished DR from DS patients, when analysing intracellular cytokines after in vitro stimulation, DR patients presented higher percentages of IL-1β and IL-6 positive monocytes compared to DS patients and HC. Circulating innate immune cells might be implicated in DR epilepsy and constitute potential new targets for treatments.

Abstract
Abstract Despite the advances made by therapeutic technologies, healthcare-associated infections (HAIs) are currently still a worldwide problem. Central-line-associated bloodstream infections (CLABSIs) are one of the most common causes of HAIs. The cost of CLABSIs is considerable, both for the increase in morbidity and financial resources expenses. Coagulase-negative staphylococci are the common pathogens responsible for CLABSIs, followed by Staphylococcus aureus, Enterococci, and Candida spp. The Enterococcus genus comprises of more than 50 species but E. faecalis and E. faecium are the most common causes of infections in humans. Enterococcus Raffinosus (ER) is a non-faecalis and non-faecium enterococcus even if ER has rarely been proven to be a human pathogen, recent reports of infections caused by enterococci that are relatively resistant to beta-lactam antibiotics by non-p-lactamase mechanisms have included strains of ER. Here we describe a first report of CLABSI due to Enterococcus Raffinosus in a cancer patient.

Abstract
A phase sensitive optical time domain reflectometry sensing scheme employing a two-stage nonlinear optical preamplification system is proposed to reduce the blind spot effect in Rayleigh scattering by improving the optical power distribution and to enhance the resolution at locations of low-backscatter intensity measurements, providing a higher signal-to-noise ratio for distributed acoustic measurements; the developed system has been tested in-laboratory and on in-field monitoring of a survey well in Cottessen, The Netherlands. The characterization shows strain noise levels below 1 nɛ for a 10 kHz sampling rate.

Abstract
Background An imbalance in host proteases has been implicated in inflammatory bowel disease (IBD). Recent evidence implicates microbial proteolytic activity (PA) in ulcerative colitis but whether it also plays a role in Crohn’s disease (CD) remains unclear. Purpose We therefore investigated the colitogenic potential and underlying pathways of proteolytic CD microbiota. Method Adult germ-free (GF) C57BL/6 mice were colonized with CD microbiota selected based on high (CD-HPA) or low fecal proteolytic activity (CD-LPA), and from healthy controls with LPA (HC-LPA), after which total fecal proteolytic, elastolytic and mucolytic activity were analyzed in the mice. Microbial community was assessed by 16S rRNA gene sequencing. Immune function and colonic injury were investigated by inflammatory gene expression (NanoString) and histology. Colitis severity and underlying pathways were investigated in C57BL/6, Nucleotide-binding Oligomerization Domain-2 knock-out (Nod2-/-), and Protease-Activated Receptor 2 (PAR2) cleavage resistant mice (R38E-PAR2) subjected to 2% dextran sodium sulfate in drinking water for 5 days followed by 2 days on water. Result(s) Colonization with HC-LPA or CD-LPA lowered baseline fecal proteolytic activity compared with GF mice, which was paralleled by lower acute inflammatory cell infiltrate. CD-HPA further increased proteolytic activity compared with GF mice. Fecal supernatants from CD-LPA or HC-LPA colonized mice had lower in vitro PAR2 cleavage compared to supernatants from GF and CD-HPA colonized mice. Several genes, such as Map kinases, Rhoa, Myd88, and Tollip, were increased in GF mice compared to colonized mice. 18 genes related to inflammation and barrier function (e.g., Mapk2k6, Tnf, Claudin1) were differentially expressed between CD-LPA and CD-HPA. CD-HPA mice had lower alpha diversity, distinct microbial profiles, and higher fecal proteolytic activity compared with CD-LPA. Abundance of several beneficial species (e.g., Akkermansia muciniphilia) was decreased while other taxa were increased (e.g., Hungattella hathewayi) in CD-HPA compared to CD-LPA. H. hathewayi as well as the serine protease K04772 were transcriptionally increased in fecal samples from CD-HPA colonized mice. C57BL/6 and Nod2-/- mice, but not R38E-PAR2 mice, colonized with CD-HPA developed earlier and more severe colitis compared with mice colonized with CD-LPA. Conclusion(s) CD proteolytic microbiota is proinflammatory through a PAR2 pathway. H. hathewayi correlates with the proinflammatory phenotype through the serine protease K04772 in this model. The results support a role of microbial PA in CD, which could constitute a biomarker for identifying patients who would benefit from anti-proteolytic therapies. Disclosure of Interest None Declared

Abstract
INTRODUCTION Multiple chemical sensitivity (MCS), is a syndrome characterised by increased sensitivity to the exposure of environmental chemicals (1). There are considerable difficulties in reaching a good estimate of the prevalence of disease and the main pathogenetic hypotheses take into account both the organic and psychiatric/psychological factors. Treatment with epidermal growth factor tyrosine kinase receptor inhibitors (tkis), like Osimertinib, results in improved progression-free survival (PFS) compared to chemotherapy, in Non-small-cell lung carcinoma (NSCLC) with epidermal growth factor receptor (EGFR) mutation (2). CASE REPORT We describe the case of a 74 year old woman with history of MCS and fibromyalgia in treatment with Osimertinib for EGFR-mutated NSCLC. Patient initially refused any form of active therapy for lung cancer, but thanks to teamwork and the important support of the psychologist, the patient decided to start treatment with Osimertinib at a reduced dose, not 80 mg but 40 mg. Subsequently, after few days , of his own free will and without informing the staff physicians, the patient changed the treatment schedule by taking one quarter of the dose of the medicine every other day, justifying this choice in therapeutic modification because of her fear and intolerance to any type of medicine and/ or chemical substance, being influenced by MCS. MANAGEMENT & OUTCOME Despite the changes in the treatment plan, a PET scan performed after two months showed a sigificative lung response and the stability of bone metastases. Discussion. Our case describes a significative response with Osimertinib despite the change in dosage and schedule in a patient with MCS. Our experience deserves to be considered in the light of its particularity and uniqueness as it shows an excellent response to treatment with Osimertinib despite the change made to the dosage and schedule, in a patient presenting in her medical history this rare pathological condition: MCS syndrome.

Abstract
PURPOSE We investigated the autophagic response of rat Müller rMC-1 cells during a short-term high glucose challenge. METHODS rMC-1 cells were maintained in 5 mM glucose (LG) or exposed to 25 mM glucose (HG). Western blot analysis was used to evaluate the expression levels of markers of autophagy (LC3-II, p62) and glial activation (AQP4), as well as the activation of TRAF2/JNK, ERK and AKT pathways. Autophagic flux assessment was performed using the autophagy inhibitor chloroquine. ROS levels were measured by flow cytometry using dichlorofluorescein diacetate. ERK involvement in autophagy induction was addressed using the ERK inhibitor FR180204. The effect of autophagy inhibition on cell viability was evaluated by SRB assay. RESULTS Activation of autophagy was observed in the first 2-6 h of HG exposure. This early autophagic response was transient, not accompanied by an increase in AQP4 or in the phospho-activation of JNK, a key mediator of cellular response to oxidative stress, and required ERK activity. Cells exposed to HG had a lower viability upon autophagy inhibition by chloroquine, as compared to those maintained in LG. CONCLUSION A short-term HG challenge triggers in rMC-1 cells a process improving the ability to cope with stressful conditions, which involves ERK and an early and transient autophagy activation.

Abstract
BACKGROUND Breast is a symbol of femininity, motherhood and sexuality. Breast cancer (BC) is the leading cause of cancer death in women worldwide and most frequent cancer in Italy: in 2019, 53.500 new cases were diagnosed. BC and its treatment, the disturbances of body image, and mental health problems such as anxiety and depression could influence sexuality. Very often the aspect of sexuality in BC is likely not to be fully investigated: cultural barriers may also contribute to lack of attention to these issues. In Italy, there are very few Breast Units that provide the figure of the sexologist and psycho-oncologist. METHODS We enlisted 141 BC patients (pts), mean age was 54 years afferent to Breast Unit S. Maria Goretti Hospital, Latina, from March 2019 to March 2020. All pts had undergone surgical intervention. Participants were invited to complete a structured questionnaire, which included four close-up questions regarding self-image, sexual activity, sexual satisfaction, analyzing these aspects before and after BC and its treatments. Finally the participants were asked if they needed the sexologist and psycho-oncologist. RESULTS Only 2/141 pts (1.41%) refused to participate in our study. Of 139 participants, 68 (48.92%) had disturbances of body image, 26 (18.7%) had sexuality greatly negatively affected, and 103 (74.1%) every kind of sexual dissatisfaction after BC. 38 pts (27.3%) would require the help of the sexologist. 135 ( 97%) would require the help of the psycho-oncologist. Despite the negative influence in their body-image and sexuality, few pts require the help of the sexologist, but nearly all pts require the help of the psycho-oncologist. CONCLUSION In our study nearly all pts require the help of the psycho-oncologist, but few pts of the sexologist. Further studies will be needed to understand the reasons for this disparity: at the moment we are carrying out another project following this illustration, with the aim of understanding why this disparity.

Introduction
Cavotricuspid isthmus ablation (CTIA) is an effective treatment for typical atrial flutter (AFL) with a recurrence rate of about 10%. A prospective multicentric registry (FLAI registry) has recently shown that a protocol including ‘point by point’ CTI ablation targeting an a quality lesion marker (Ablation Index AI) ≥ 500 and a maximum inter-lesion distance (ILD) measurement of ≤6 mm allowed an acute success rate of 98.3%. In this study, we aimed to describe the incidence and predictors of recurrence of both AFL and atrial fibrillation (AF) in a long-term follow-up of the patients enrolled in the FLAI registry.
Methods
The FLAI registry was a multicentric non-randomized study that enrolled 412 consecutive patients (mean age 64.9±9.8; 72.1% males; 27.7% with structural heart disease). Patients with typical AFL underwent an AI-guided cavotricuspid isthmus ablation. The procedures targeted an AI of 500 and an ILD measurement of ≤ 6mm. The primary endpoints were CTI ‘first pass’ block and persistent block after a 20-minute waiting period. The CTI bidirectional "first pass block" was reached in 355 patients (88.3%), whereas CTI block at the end of the waiting period was achieved in 405 patients (98.3%). No complications were reported.
The mean time of follow-up was 21±4.24 months and it was available for 397 patients. The FU included outpatient clinical evaluation, ECG and 24-h Holter ECG at three, six- and 12-months post-ablation, followed by an annual clinical evaluation and ECG. Documented ECG Atrial fibrillation events, in follow up, were also included in the data set.
Results
Atrial flutter recurrence: 22 AFL events were observed (5.5%) at 34 months. According to the Kaplan Meier analysis, the growth of recurrence rate was constant between 6 and 12 months, after 19 months recurrences were unlikely. At the univariate analysis predictors of AFL recurrence were: absence of bidirectional block after the waiting time period (p= 0,001); failure of the CTIA index procedure (p=<0,0005); ablation line lengths > 32 mm (p=0.,018), number of automatic ablation lesion tags (VISITAG) > 20 (p=0,.005) and At the increathe reported numbers of ‘g"gap’" in the ablation line lengths: the more the gaps increase the more the probability of AFL recurrence in FU increases (p=0.,037).
In the Multivariate aAnalysis, the independent predictors of AFL recurrence were: the procedural success and the number of VISITAG (OR =1.062)
Atrial fibrillation recurrence: 45 patients developed atrial fibrillation after CTI ablation (11.3%). In the multivariate analysis, the major independent predictor was a documented pre-procedural Afib and the risk increases with the younger age (< 53 yo).
Conclusions
The FLAI protocol is safe, reproducible and effective in the follow-up, with a long term success of 94,5%. The reported incidence of atrial fibrillation in FU was 11,3%

Background
Ventricular tachycardia (VT) ablation targeting conducting channels (CC)s based on timing of late potentials (LPs) during sinus rhythm (dechanneling) may facilitate a scar homogenization strategy without the need for extensive ablation and possibly lead to higher successful rate.
Purpose
We evaluated the feasibility and safety of a CC identification and ablation approach by means of an ultra-high density mapping system with a novel automated algorithm in ischemic VT procedures.
Methods
Consecutive patients indicated for ischemic VT ablation were prospectively included. A complete map of the left ventricle was performed prior and after ablation through the Rhythmia mapping system. Channels were defined as any signal activity bounded by anatomic and functional barriers and characterized through the Lumipoint (LM) tool and continuous activation was used on the whole ventricular substrate. Procedural end point was the elimination of all identified CCs by ablation at the CC entrance and exit followed by abolition of any residual LPs inside the CC. The ablation endpoint was noninducibility. Data are reported as mean±SD.
Results
A total of 36 channels were identified through LM from 28 patients (1.2±0.5 per patient): 21 (75%) patients had 1 CC, 6 (21.4%) had 2 CCs and 1 (3.6%) had 3 CCs. LPs were identified inside CCs in 19 cases (67.9%). In 8 cases (28.6%) LPs were present both inside and outside and in 1 (3.6%) case LPs were present only outside the CC. LPs inside channels covered an area of 7.6±5 mm2 with a ratio between LPs area and CCs’ area of 67.4±31.8%. In 12 (43%) cases LPs area covered more than 90% of the CCs’ area. At voltage map analysis a total of 34 CC were identified: 1 CC was present in 75% of the cases, 2 CCs in 17.9% and 3 CCs in 3.6%. LPs were identified only inside CCs in 46.4% of the cases, both inside and outside in 42.9% and only outside in 10.7%. Healthy tissue (voltage level≥0.5mV) was prevalent (68.2±17%), followed by intermediate voltage areas (0.5-0.05 mV; 31.1±17%) and very low voltage areas (<0.05mV; 0.7±1%). LPs were found mostly at intermediate voltage areas (57.0±34% of the covered area; 39.1±33% at healthy tissue and 3.4±13% at very low voltage areas). LM was more accurate than traditional voltage mapping in identifying CCs: in 6 (21.4%) cases voltage map overestimated LPs areas, in 2 (7.1%) cases failed to fully identify LPs and only in 19 out 28 (67.8%) LM and voltage map had a complete agreement. All CCs’ entrance and exit were successfully ablated and abolition of any residual LPs inside the CC was achieved in all patients. No complication occurred. Noninducibility was achieved in all (100%) the cases.
Conclusions
In this experience, a channel identification approach through the advanced Lumipoint tool was more accurate than traditional voltage mapping and seems to be safe, feasible, and effective at least in the acute setting of ischemic VT ablation.

Abstract
Abstract
Background
Worldwide, cardiovascular disease are still a major mode of death, being sudden arrhythmic death (SCD)25 % of total death. Implantable cardioverter defibrillator (ICD) is an effective weapon for SCD prevention in high risk patients with reasonable expectation of survival with good functional status for >1 year. However sometimes the risk of SCD can be transient, so the use of a wearable cardioverter defibrillator (WCD) is considered.
Methods
We considered consecutively 40 patients discharged from our cardiology department of Piacenza and Castel san Giovanni that, for potentially transient high risk of SCD, weared a WCD from August 2017 to September 2021, after a systematic education session lasting 30 – 45 minutes. They are followed through remote monitoring.
Results
Out of 40 patients, with average age 66 years old and average left ventricular ejection fraction (LVEF) 29%, 88% were males, 70 % suffered from arterial hypertension, 32% diabetes mellitus, 17,5 % peripheral vascular disease, 35 % chronic renal failure, 55% heart failure, 7,5% previous stroke. 56% of these patients weared WCD for severe systolic disfunction in ischemic cardiac disease after recent myocardial infarction, after percutaneous coronary intervention or coronary artery bypass graft, 7% after removal of an infected ICD, 9 % whilst awaiting completion of diagnostic tests (chanalopathies/right arrhythmogenic ventricular cardiomyopathy), 34% after newly diagnosed cardiomyopathy.The patients were discharged in high risk mode of SCD with WCD protection.The average wearing time of WCD was 51 days and 22,98 hours daily. We received 953 trasmissions, with 21 events: 7 ventricular tachicardia, 4 Sopraventricular tachicardia and 5 T wave oversensing .Neither inappropriate shock and neither death were detected .After wearing time and after clinical evaluation, only 52% of patients were subjected to ICD implantation.
Conclusions
In our experience we may consider that WCD use is effective, safe and with a good adherence in all patients, considering wearing time. The WCD allows saving resources with less hospitalization time.

Abstract
Abstract
Background
The wearable cardioverter defibrillator (WCD) is considered in patients with increased risk of sudden cardiac death (SDC), in which implanted cardiac defibrillator (ICD) is temporary not definitively indicated. A few registry confirmed efficacy and safety of WCD and left ventricular ejection fraction recovery (LEVS)after wearing time.
Methods
We considered in our study 40 consecutively patients that used WCD in Piacenza and Castel San Giovanni Cardiology Department from August 2017 to September 2021 with recent acute myocardial infarction, newly diagnosed cardiomyopathy, primary arrhythmias syndrome awaiting diagnostic completation. They were followed by remore monitoring. The primary outcome were: the need of ICD implantation or not indication to ICD at the of the wearing time, We analyzed clinical variables related to primary outcome.
Results
Out of 40 patients, average age 66 years, average LEVS media 29%±12,5,88% were males, 32% suffered from diabetes mellitus, 35% renal failure, 55% acute and chronic heart failure, 10% previous ischemic stroke, 17% atrial fibrillation (AF), 12% cardiac arrest (ACC) after STEMI onset, 20% ventricular tachicardia (VT). 27% of these patients took amiodarone,92% beta blockers and 82% ACEi.The average wearing time of WCD was 51 days and 22,96 hours dailyAt the end of this period 48% of patients didn‘t receive ICD implantation for increasing LEVS.We evaluated clinical variables related to primary outcome with Chi Square test and Student’s t test.There weren’t significant difference regarding primary outcome between ischemic disease and other cardiophaties. The presence of AF, previous stroke, renal failure, hypertension, diabetes mellitus was more but not significant in ICD group. No significant age difference(66.8±14.1 vs 66.3±11.8, p = 0,6) neither FEVS (29.4±11.6 vs 29.5±12.7, p = 0,8) was in patients that received ICD versus not received .The clinical variables related to primary outcome only were: ACC after STEMI onset and amiodarone therapy.
Conclusions
In our study of patients with WCD, the percentage of LEVS increase is consistent with European registries. A few clinical variables may be related to ICD indication. Further studies can be useful to identify patients who need more of WCD for a lack of LEVS improvement.

BACKGROUND
The debate about the independent prognostic responsibility of functional mitral regurgitation (FMR) is still in turmoil. Growing findings about the predictive role of left atrial (LA) function are emerging in several scenarios.
PURPOSE
This study aims to define FMR linkage to cardiovascular (CV) outcomes and the interplay with LA function in a prospective cohort of consecutive heart failure patients with reduced ejection fraction (HFrEF).
METHODS
286 consecutive outpatients with chronic HFrEF were enrolled. FMR was quantified by effective regurgitant orifice area (EROA). Global peak atrial longitudinal strain (PALS) was measured by speckle tracking echocardiography (STE). The primary endpoint was defined as a composite of congestive HF hospitalization and CV death.
RESULTS
The majority (81%) of patients were men (mean age: 67 ± 11 years, mean LVEF: 32 ± 6%). The median global PALS was 17.7% ranging from 2.7% to 49.2%. FMR was quantifiable in 240 (84%) patients. During a median follow-up period of 6.4 (IQR 3.9-7.7) years, the primary endpoint occurred in 88 (31%) patients (35 HF admissions, and 53 deaths). EROA showed independent prediction for the primary endpoint (HR 1.30 [1.05-1.57], P = 0.01). The spline modeling of the risk by EROA values showed an excess event risk starting at about the EROA value of 0.1 cm2 (Figure 1). There was a remarkable graded association between the EROA strata, even if tested per 0.1 cm2 increase, and the risk of congestive HF hospitalization and CV death (P = 0.0004). Any FMR grade presenting with reduced LA function (PALS < 14%) was associated with dismal outcome (event rate of 63 ± 10% for EROA exceeding 0.3 cm2 and 49 ± 6% for EROA ≥0.1 cm2 at 5 years). Conversely, the presence of EROA ≥0.1 in the context of preserved global PALS showed a better outcome (Figure 2).
CONCLUSIONS
Our results refine the independent association between FMR and CV outcome among HFrEF outpatients. The risk of CV events starts at a low EROA value, reaching a severe level above the threshold of 0.3 cm2. Within a moderate EROA range, the LA function mitigates the clinical consequences of the mitral regurgitation, providing measurable proof of the interplay between the regurgitation and the LA compliance.

Abstract
PURPOSE To assess the incidence of incisional hernia (IH) across various type of incisions in colorectal surgery (CS) creating a map of evidence to define research trends, gaps and areas of future interest. METHODS Systematic review of PubMed and Scopus from 2010 onwards. Studies included both open (OS) and laparoscopic (LS). The primary outcome was incidence of IH 12 months after index procedure, secondary outcomes were the study features and their influence on reported proportion of IH. Random effects models were used to calculate pooled proportions. Meta-regression models were performed to explore heterogeneity. RESULTS Ninetyone studies were included reporting 6473 IH. The pooled proportions of IH for OS were 0.35 (95% CI 0.27-0.44) I2 0% in midline laparotomies and 0.02 (95% CI 0.00-0.07), I2 52% for off-midline. In case of LS the pooled proportion of IH for midline extraction sites were 0.10 (95% CI 0.07-0.16), I2 58% and 0.04 (95% CI 0.03-0.06), I2 86% in case of off-midline. In Port-site IH was 0.02 (95% CI 0.01-0.04), I2 82%, and for single incision surgery (SILS) of 0.06-95% CI 0.02-0.15, I2 81%. In case of stoma reversal sites was 0.20 (95% CI 0.16-0.24). CONCLUSION Midline laparotomies and stoma reversal sites are at high risk for IH and should be considered in research of preventive strategies of closure. After laparoscopic approach IH happens mainly by extraction sites incisions specially midline and also represent an important area of analysis.
