Abstract
The emergence of Omicron lineages and descendent subvariants continues to present a severe threat to the effectiveness of vaccines and therapeutic antibodies. We have previously suggested that an insufficient mucosal immunoglobulin A (IgA) response induced by the mRNA vaccines is associated with a surge in breakthrough infections. Here, we further show that the intramuscular mRNA and/or inactivated vaccines cannot sufficiently boost the mucosal secretory IgA response in uninfected individuals, particularly against the Omicron variant. We thus engineered and characterized recombinant monomeric, dimeric, and secretory IgA1 antibodies derived from four neutralizing IgG monoclonal antibodies (mAbs 01A05, rmAb23, DXP-604, and XG014) targeting the receptor-binding domain of the spike protein. Compared to their parental IgG antibodies, dimeric and secretory IgA1 antibodies showed a higher neutralizing activity against different variants of concern (VOCs), in part due to an increased avidity. Importantly, the dimeric or secretory IgA1 form of the DXP-604 antibody significantly outperformed its parental IgG antibody, and neutralized the Omicron lineages BA.1, BA.2, and BA.4/5 with a 25- to 75-fold increase in potency. In human angiotensin converting enzyme 2 (ACE2) transgenic mice, a single intranasal dose of the dimeric IgA DXP-604 conferred prophylactic and therapeutic protection against Omicron BA.5. Thus, dimeric or secretory IgA delivered by nasal administration may potentially be exploited for the treatment and prevention of Omicron infection, thereby providing an alternative tool for combating immune evasion by the current circulating subvariants and, potentially, future VOCs.

Abstract
CEMIP (cell migration-inducing protein), also known as KIAA1199 or HYBID, is a protein involved in the depolymerisation of hyaluronic acid (HA), a major glycosaminoglycan component of the extracellular matrix. CEMIP was originally described in patients affected by nonsyndromic hearing loss and has subsequently been shown to play a key role in tumour initiation and progression, as well as arthritis, atherosclerosis and idiopathic pulmonary fibrosis. Despite the vast literature associating CEMIP with these diseases, its biology remains elusive. The present review article summarises all the major scientific evidence regarding its structure, function, role and expression, and attempts to cast light on a protein that modulates EMT, fibrosis and tissue inflammation, an unmet key aspect in several inflammatory disease conditions.

Abstract
MYC is a pleiotropic transcription factor involved in cancer, cell proliferation, and metabolism. Its regulation and function in NK cells, which are innate cytotoxic lymphocytes important to control viral infections and cancer, remain poorly defined. Here, we show that mice deficient for Myc in NK cells presented a severe reduction in these lymphocytes. Myc was required for NK cell development and expansion in response to the key cytokine IL-15, which induced Myc through transcriptional and posttranslational mechanisms. Mechanistically, Myc ablation in vivo largely impacted NK cells' ribosomagenesis, reducing their translation and expansion capacities. Similar results were obtained by inhibiting MYC in human NK cells. Impairing translation by pharmacological intervention phenocopied the consequences of deleting or blocking MYC in vitro. Notably, mice lacking Myc in NK cells exhibited defective anticancer immunity, which reflected their decreased numbers of mature NK cells exerting suboptimal cytotoxic functions. These results indicate that MYC is a central node in NK cells, connecting IL-15 to translational fitness, expansion, and anticancer immunity.

Abstract
Background The aim of our study was to assess how total intra-venous anaesthesia (TIVA) achieved by propofol and remifentanil continuous infusion could ensure proper success of the endobronchial laser therapy, in optimal conditions for the endoscopist, determining at the same time an adequate hypnosis and a good analgesia. Methods We studied 50 patients (28M - 22F), ASA class I-IV, mean age 42 ± 32.5 years , subjected to laser endoscopy to repair tracheal stenosis. TIVA was performed in all patients, and spontaneous breathing was maintained. Results 10.2% of patients experienced episodes of coughing during induction. The depth of the anaesthesia plan, monitored by BIS, was 55 ± 5. The awakening was fast in all patients, with an Aldrete score of 7.71 ± 1.14 at 1 minute and 9.31 ± 1.12 at 10 minutes. Conclusion The results of this study allow us to state that the continuous infusion of propofol and remifentanil proved to be the gold standard in patients ASA I-II-III undergoing endobronchial laser therapy. The use of TIVA has also allowed to perform endoscopic intervention on patients who suffered from a significant decrease of both cardiac and respiratory functions.

Abstract
Emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants diminishes the efficacy of vaccines and antiviral monoclonal antibodies. Continued development of immunotherapies and vaccine immunogens resilient to viral evolution is therefore necessary. Using coldspot-guided antibody discovery, a screening approach that focuses on portions of the virus spike glycoprotein that are both functionally relevant and averse to change, we identified human neutralizing antibodies to highly conserved viral epitopes. Antibody fp.006 binds the fusion peptide and cross-reacts against coronaviruses of the four genera, including the nine human coronaviruses, through recognition of a conserved motif that includes the S2' site of proteolytic cleavage. Antibody hr2.016 targets the stem helix and neutralizes SARS-CoV-2 variants. Antibody sd1.040 binds to subdomain 1, synergizes with antibody rbd.042 for neutralization, and, similar to fp.006 and hr2.016, protects mice expressing human angiotensin-converting enzyme 2 against infection when present as a bispecific antibody. Thus, coldspot-guided antibody discovery reveals donor-derived neutralizing antibodies that are cross-reactive with Orthocoronavirinae, including SARS-CoV-2 variants.

Abstract
Emergence of SARS-CoV-2 variants diminishes the efficacy of vaccines and antiviral monoclonal antibodies. Continued development of immunotherapies and vaccine immunogens resilient to viral evolution is therefore necessary. Using coldspot-guided antibody discovery, a screening approach that focuses on portions of the virus spike that are both functionally relevant and averse to change, we identified human neutralizing antibodies to highly conserved viral epitopes. Antibody fp.006 binds the fusion peptide and cross-reacts against coronaviruses of the four genera , including the nine human coronaviruses, through recognition of a conserved motif that includes the S2' site of proteolytic cleavage. Antibody hr2.016 targets the stem helix and neutralizes SARS-CoV-2 variants. Antibody sd1.040 binds to subdomain 1, synergizes with antibody rbd.042 for neutralization and, like fp.006 and hr2.016, protects mice when present as bispecific antibody. Thus, coldspot-guided antibody discovery reveals donor-derived neutralizing antibodies that are cross-reactive with Orthocoronavirinae , including SARS-CoV-2 variants. One sentence summary Broadly cross-reactive antibodies that protect from SARS-CoV-2 variants are revealed by virus coldspot-driven discovery.

Abstract
Introduction
22q11.2 deletion syndrome is the most common microdeletion syndrome. Its clinical presentation varies and it may present several medical complications, namely heart defects, cleft palate, autoimmune diseases, delayed development, and psychiatric disorders. In these patients, psychiatric disorders are frequent and may include attention-deficit hyperactivity disorder, anxiety disorders, autism spectrum disorder, and schizophrenia spectrum disorders.
Objectives
We aim to characterize psychosis in patients diagnosed with 2q11.2 deletion syndrome, which is one of the most frequent psychiatric presentations.
Methods
To introduce the topic of 22q11.2 psychiatric symptoms, we will start by presenting a clinical case. Then, a review of the related literature using the Pubmed database using the following expression “22q11.2 deletion syndrome”; “DiGeorge syndrome”; “velocardiofacial syndrome”; “psychosis”; “psychiatric disorders”.
Results
Patients diagnosed with 22q11.2 deletion syndrome are considered high-risk for psychosis. In this clinical case, we present a 19-year old man diagnosed with 22q11.2 deletion syndrome who was admitted to a psychiatric ward for psychosis. The knowledge of the increased risk for psychosis in these patients should be taken into account in the face of behavioral changes de novo to assure a timely therapeutic approach. Currently, the treatment does not differ from other patients, but this is mainly due to the lack of knowledge on the best therapeutic approach in this specific diagnosis.
Conclusions
Genetic syndromes are often associated with psychiatric disorders. Patients diagnosed with 22q11.2 deletion syndrome are at high risk for psychosis and should deserve a multidisciplinary approach so that their diagnosis and treatment are established as early as possible.
Disclosure
No significant relationships.

Abstract
Catheter dislocation and fracture with migration of central venous lines have been reported in the International literature. Catheter fracture with consequent migration has been observed in 0.5-3.0% and may either be consequent to catheter removal or it can occur spontane-ously. Our case report concerns the migration of a Hickman catheter connected to a venous port to the right atrium in a 61-year old patient. A literature up-to-date has been performed to assess the risk of port-a-cath positioning. The position of catheter tip is considered critical for the risk of migration, that is greater as higher the tip localization respect to the carina. The aim of our study is to underline the critical role of X-ray to visualize the exact location of the catheter tip, regard-less of the approach used for catheter positioning.

Abstract
Abstract

Type of funding sources: None.
Background
Cavotricuspid isthmus (CTI) ablation in patients with typical atrial flutter (AFL) has improved in the past years, especially by the use of threedimensional (3D) electroanatomic mapping systems. These mapping tools contributed to reduce radiation exposure, but most ablation procedures still require varying amounts of fluoroscopy.
Purpose
We aim to examine whether fluoroless CTI ablation is effective and safe in reducing AFL recurrence, compared with CTI ablation using fluoroscopy and a 3D mapping system.
Methods
A retrospective analysis of CTI ablation procedures performed at a tertiary center between December 2008 and December 2020 was conducted. Cases were divided in two groups: fluoroless and fluoroscopic, according to the use of radiation. Procedural duration, fluoroscopy time (FT), use of 3D mapping system, complications and recurrence rate at one year were analyzed.
Results
A total of 324 CTI ablations performed on patients with documented typical AFL were included. Mean age was 62.3±14.0, with 78.1% male patients. Fluoroless ablations were performed based on a 3D mapping system, and all fluoroscopic procedures also used 3D electroanatomic mapping. The FT was zero in the fluoroless group - 31 cases (9.6%), and 7.0±4.4 minutes in the fluoroscopic group - 291 cases (90.4%) (p<0.001). There was no statistically significant difference between the two groups, regarding AFL recurrence at one year (21.7% in the fluoroless group versus 13% in the fluoroscopic group; odds ratio [OD] 0.54; 95% confidence interval [CI] 0.18-1.62; p=0.27). Total procedure duration was significantly shorter in the fluoroless group (1h07m versus 1h40m; t-test 4.261, p<0.001, CI 0h16m-0h50m). There were no acute complications for both groups.
Conclusion
Fluoroless CTI ablation avoids radiation exposure to the patient and operator and can be performed in patients with typical AFL, without compromising duration, safety or efficacy of the procedure.

Abstract

Background
Pulmonary vein isolation (PVI) is the mainstay of catheter ablation (CA) for atrial fibrillation (AF). Strategies have been proposed to improve the success rate of CA, such as prophylactic cavotricuspid isthmus (CTI) ablation. Despite some studies providing no, or limited, incremental benefit of CTI ablation in patients with AF, it is still frequently performed worldwide.
Purpose
The aim of this study is to examine whether CTI ablation, combined with PVI, is associated with improvement in recurrence of AF, compared with PVI alone in AF patients with or without atrial flutter (AFL).
Methods
We conducted a retrospective analysis of CA for AF performed at a tertiary center between September 2004 and December 2020. The procedures were divided in two groups: "PVI alone" and "PVI plus CTI ablation". Demographic, clinical, and procedure related data was retrieved. Atrial fibrillation recurrence rate at one year was analyzed for both groups and compared using logistic regression.
Results
A total of 453 procedures were analyzed: PVI alone (n=378; 83.4%) and PVI with CTI ablation (n=75; 16.6%). In the PVI alone group, 12.9% of the patients had concomitant typical AFL and in the PVI plus CTI ablation, 45.8% had typical AFL. Mean age was 57.3±12.1 years, with 63.6% male patients. At one year, AF recurrence rate was higher in the combined PVI with CTI ablation group (30.4%; n=21), compared with the PVI alone group (28.4%; n=97), with no statistical difference between the two groups (Odds Ratio [OD] 1.10; 95% confidence interval [CI] 0.62-1.94; p=0.73). In the subgroup analysis, there was no difference in recurrence between patients with AF without AFL (OR: 1.9; 95% CI: 0.39-9.36; p=0.43), and in patients with AF with concomitant AFL (OR: 10.0; 95% CI: 0.9-110.3; p=0.06).
Conclusion
In AF patients, irrespective of the presence of typical AFL, additional CTI ablation, compared with PVI alone, was not associated with improvement in recurrence of AF.

Abstract
Abstract

Type of funding sources: None.
Background
Focal atrial tachycardia (AT) is a relatively uncommon arrhythmia with poor response to medical treatment. Radiofrequency (RF) ablation appears to be a good option for treatment of symptomatic patients (P).
Purpose
To describe the clinical characteristics, electrophysiological (EP) findings, safety and short-term efficacy of catheter ablation in P with AT.
Methods
Retrospective analysis of consecutive P submitted to AT ablation using electroanatomical mapping between 2015 and 2020. If the AT was not present spontaneously, pacing maneuvers (atrial drive or burst pacing with up to 3 extra-stimuli) and isoprenaline was employed until reproducible induction of an ectopic atrial rhythm. Radiofrequency (RF) ablation was delivered at the site of earliest activation after validation of local electrograms until non-inducibility.
Results
A total of 46P (61% female) were included, with a mean age of 48 ± 23 years (minimum 8 months, maximum 86 years). Idiopathic AT was observed in 47,8%, while 52.2% had other relevant comorbidities (chronic pulmonary disease 17.4%; previous cardiac surgery 8,7%; congenital heart disease 10.9%; coronary artery disease 6.5%). Despite anti-arrhythmic therapy, daily palpitations were present in 87% of the cases and dizziness or syncope occurred in 22%). Nearly half (47.8%) had previously sought urgent medical care and 30.4% had a hospital admission due to arrhythmia. The clinical arrhythmia was documented in 34P (47.8% by 12-lead electrocardiography and 26.1% in 24h Holter monitoring). During the EP study a focal AT was documented in all P (spontaneously in 54.3% and induced with pacing maneuvers in 45.7%). AT origin after electroanatomical activation mapping is depicted in figure 1. After focal RF ablation, a second AT was induced in 16P (34.8%) and a new ablation was performed in 15 cases (93.8%). Total RF time was 508 ± 386 sec. One P developed right phrenic nerve palsy after ablation on the lateral wall of the right atrium. No other complications were noted. On follow-up (mean 320 ± 92 days), symptoms improved in 88.1% of the P, with a 3-fold decrease in urgent medical care visits and hospital admission for arrhythmia. Three P (8.7%) were submitted to a new EP study, in which an AT was documented and ablated in 2P.
Conclusion
AT is a very symptomatic arrhythmia, associated with increased usage of hospital resources and poor response to antiarrhythmic therapy. Ablation is an efficient treatment option, with a high success rate, low rate of complications and short-term clinical benefits. Abstract Figure. Distribution of focal atrial tachycardia

Background
During electrophysiology (EP) procedures, fluoroscopy imaging is employed to visualise catheters position in real-time. However, ionizing radiation is a health hazard to both the patient and operator. In recent years, the use of electroanatomical mapping systems and operator adoption of low-fluoro workflows has allowed a reduction of radiation exposure. The aim of this study was to assess the evolution of fluoroscopy time (FT) in EP procedures, using conventional technique or an electroanatomical mapping system (EMS).
Methods
A retrospective analysis of consecutive EP procedures performed at a tertiary centre between September 2018 and October 2020 was conducted. The procedures were divided in 3 tertiles according to date (T1, T2 and T3), with T3 corresponding to the most recent interventions. Procedural duration, FT, use of EMS, radiofrequency time (RT), acute ablation success and procedural complications were examined.
Results
A total of 615 procedures were analysed: atrioventricular node reentry tachycardia (AVNRT) – n = 144, accessory pathways (AP) – n = 83, typical atrial flutter – n = 106, atrial fibrillation (AF) ablation with radiofrequency (RF) – n = 61, AF ablation with cryoballoon – n = 92, ablation of ventricular arrhythmias – n = 53, and 75 miscellaneous procedures (including atrioventricular node ablation, left atrial flutter ablation and cardioneuroablation). Mean age was 54.6 ± 18.2 years with 59.4% male sex patients. An EMS was used in 75% of the procedures, without significant differences between tertiles. A progressive reduction in median FT was observed over the tertiles (T1 6.3 min, interquartile range [IQR] 2.9-13.6; T2 5.4 min, IQR 2.1-12.0, and T3 3.1 min, IQR 1.2-7.2, Figure 1), and a statistical significant difference was found when comparing T1 to T3 (p < 0.001) and T2 to T3 (p < 0.001). The decrease in FT was observed throughout the study period for all different EP procedures (Figure 2). The number of procedures with zero fluoroscopy had gradually increased (T1 6.1%, T2 8.5% and T3 14.1%; T1 vs. T3 p <0.01). Younger patients (<20 years) were submitted to low fluoroscopy doses with a significant decrease over tertiles (T1 1.2 min, IQR 0.0-4.3; T2 0.9 min, IQR 0.0-2.5; T3 0.0, IQR 0.0-2.2, T1 vs.T3 p < 0.001). No significant difference in procedural duration, RT, acute procedural success or complication rate were noted between tertiles.
Conclusion
Reduction in radiation exposure can be achieved without compromising duration, safety and effectiveness of the procedure. The commitment of operators to reduce radiation exposure using 3D mapping technology can lead to a significant decrease in the use of fluoroscopy. Abstract Figure. Fluoroscopic time analysis

Abstract
Genome Resource Banks are keystones in the ex-situ conservation of wild species. Post-mortem (PM) collection of epididymal spermatozoa is an opportunistic and valuable source of germplasm, the time from the death of the animal limits its use. Seeking to improve germplasm preservation strategies for the chamois (Rupicapra sp.), the effect of PM time on epididymal sperm quality and freezability was studied using the Cantabrian chamois. Samples were classified according to PM collection time, up to 216 h (refrigerated), and cryopreserved (Tris-citric acid-fructose, 430 mOsm/kg, 15% egg yolk, 8% glycerol; freezing at -20 °C/min). Sperm quality was assessed after recovery and post-thawing (motility by CASA, HOS test, abnormal forms, cytoplasmic droplets, and viability and acrosomal damage by flow cytometry). The sperm mass pH and osmolality showed a positive correlation with time. Total sperm motility dropped after 2 days PM, with progressivity and sperm velocities remained similar up to 3 days PM. Sperm freezability was acceptable, with the post-thawing HOST, motility, progressivity, VAP, VCL, VSL and BCF negatively correlating with PM time. Overall, chamois epidydimal samples were not adequate for preservation after 6 days PM. Freezability capacity could make these spermatozoa suitable for specific ART even if kept refrigerated for several days PM.

Abstract
Introduction : L’évaluation du temps de travail en soins infirmiers est une pratique courante aux soins intensifs. Elle permet de calculer un ratio infirmière/patient optimal qui est un enjeu majeur pour assurer la qualité des soins et maîtriser les coûts des soins de santé. Le Nursing Activities Score (NAS) permet de calculer ce ratio, mais l’outil n’a jamais été traduit en français et adapté à la Belgique.
Objectif : Traduire et adapter le NAS à la Belgique francophone.
Méthodes: L’échelle a été traduite par deux traducteurs indépendants de l’anglais vers le français. Ensuite, une traduction rétrograde du français à l’anglais a été réalisée. Une adaptation culturelle a été effectuée en réunissant un groupe de 13 infirmiers belges. Enfin, l’échelle traduite a été validée et implémentée dans deux unités de soins intensifs (USI) distinctes en Belgique francophone.
Résultats : La traduction rétrograde était similaire à la première traduction. La réunion avec le groupe d’experts a permis de trouver un consensus sur l’adaptation de l’échelle et le tutoriel adaptés au contexte des soins en Belgique. Pour la validation, le NAS a été encodé chez 113 patients et avec 981 NAS encodés dans deux USI, la médiane de NAS/patient était respectivement de 69 et 76 %. Le temps médian d’encodage du NAS était de trois minutes par patient. Nous avons observé une compliance élevée de l’encodage du NAS (respectivement 99 et 76 %).
Conclusions : Nous avons validé une échelle traduite en français conforme à la version originale et adaptée au contexte des soins en Belgique.

Abstract
Abstract
Background: Underserved breast cancer survivors are typically offered fewer opportunities to participate in cancer research. To address this disparity, a community based navigator program, Shanti's Margot Murphy Breast Cancer Program (Shanti) initiated a collaboration with UCSF researchers and BreastCancerTrials.org (BCT), a nonprofit clinical trials matching service to explore the potential role of a trusted community-based organization as a source of culturally appropriate education and access to clinical trial information. Through formative research, we developed the Health Research Engagement Intervention (HREI), a one-on-one navigator-client education session emphasizing the range of treatment and non-treatment quality-of-life and observational studies, conducted at a time when the participant is not in the initial crisis of diagnosis. The HREI ends by providing participants with an information card listing BCT and other organizations that provide information about health research for breast cancer patients and survivors.
Methods: We tested the HREI in a randomized controlled trial, comparing the HREI to simply providing the information card. Pre and post intervention surveys one month apart measured our primary outcome of health research information-seeking behavior. Secondary outcomes include health research knowledge, attitudes towards research participation, and health empowerment. All Shanti clients who spoke English, Cantonese or Spanish and had “low care navigation needs” (either completed treatment or no longer in the crisis of initial diagnosis and/or burdened by treatment protocols) were eligible.
Results: We recruited 133 Shanti Clients, including 59 who spoke English, 48 Cantonese, and 26 Spanish; 66 were randomized to the intervention arm and 67 to the control arm, and 130 completed both pre- and post-test surveys. Almost one-third of participants in both the intervention and control arms reported having talked to someone about health research or having called a telephone number or visited a website listed on the card (30% vs. 30%, p=0.94); a smaller proportion of participants confirmed that their information-seeking was related to the content of the educational materials (17% vs. 9%, p=0.22). On average the change from pre- to post-test in a 5-item knowledge score, adjusted for pre-test knowledge, was greater in the intervention group than in the control group (p=0.028), but the proportion of participants who were very confident that they could find health research information (had health empowerment) remained essentially unchanged in both study arms (intervention: 20% post vs. 21% pre, p=0.76; control: 25% post vs. 25% pre, p=1.00). Women were more likely to seek information if they had higher pre-test knowledge scores (odds ratio [OR]=3.5 per item, 95% confidence interval [CI] 1.5-8.4) or a greater increase in knowledge from pre- to post-test (OR=2.2 per item, 95% CI 1.1-4.7); there was no association between information-seeking and health empowerment (OR=0.6, 95% CI 0.2-2.5) or study arm (OR=1.6, 95% CI 0.5-4.9).
Conclusion: The HREI had a positive impact on knowledge of health research but did not significantly affect health empowerment or health research information-seeking behavior.

Abstract
Abstract
Background: Nipple-areola tattoos can provide restoration of a natural looking breast that more closely resembles its pre-surgical appearance while avoiding additional surgeries. To date, the majority of nipple-areola tattoo procedures are performed by healthcare providers with minimal training in tattoo procedures. Substandard results explain the high rates of dissatisfaction among women who receive nipple-areola tattoos. In response, professional tattoo artists have emerged as an alternative provider for women seeking reconstruction. However, few studies have examined expectations and experiences of women undergoing nipple-areola tattoo procedures provided by a professional tattoo artist outside of the traditional healthcare setting. Methods: In-depth interviews were conducted with a racially/ethnically diverse group of 30 women who had undergone nipple-areola tattooing in the past 0-2 years. Interviews were conducted in English, Spanish, Chinese, and Arabic, recorded, and translated and transcribed into English for analysis. A team of three researchers conducted iterative reviews of the data which included closely reading each transcript, coding, running queries of codes, and developing summary documents to highlight recurrent concepts and patterns which were shared and discussed in group meetings. Results: Interview narratives addressed the often unexpected impact nipple-areola tattooing had on body image, self-esteem, emotional well-being, and interpersonal relationships. Women described their decision-making processes as weighing concern about the needle, the pain, and uncertainty about the tattoo artist, setting for the procedure, and outcome with the opportunity to return to a more “normal” appearance without further surgeries. Women discussed how their initial preconceptions of tattoos and tattoo parlors were ameliorated by the spa-like setting and the tattoo artist's anticipation of such concerns which enhanced her ability to put them at ease and provide professional and compassionate care. Participants noted the integral role the tattoo artist played in their positive experiences, describing her as both an “artist” and “caregiver.” The manner in which she guided them through the decision-making process regarding the color, size, shape, and placement of their nipple-areola tattoo was noted as particularly significant and empowering. Conclusions: Nipple-areola tattooing is an acceptable and meaningful reconstruction process for medically underserved public hospital patients. Our results indicate that women should be informed of nipple-areola tattooing as an alternative to more invasive, surgical reconstruction options. Results also illustrate how the healthcare system can extend beyond the traditional healthcare setting to include and leverage non-clinical and non-traditional specialists to provide appropriate care and positive breast health outcomes for women. In order to increase access and legitimacy to these services, additional research is needed to understand how to bring tattoo artists “in-house” (i.e., into the medical setting) and how to incorporate tattoo artists into breast health teams.

Abstract
Abstract
As genetics and genomics become part of mainstream Medicine, these advances have the potential to reduce or exacerbate health disparities. Gaps in effective communication (where all parties share the same meaning) are widely recognized as a major contributor to health disparities. The purpose of this study was to examine cancer genetic counselor-patient communication, to assess its effectiveness from the patient perspective, and to pilot intervention strategies to improve it. We used multiple inductive methods, including standard ethnographic techniques to systematically observe and audio-record genetic counseling sessions, and qualitative interviews with observed patients using the audio recordings to stimulate recall and probe specific aspects of the communication. Data analyses were conducted using grounded theory. We observed 64 English-, 35 Spanish- and 25 Cantonese- speaking public hospital patients (n = 124) and 10 Genetic Counselors in 170 appointments, and interviewed 49 patients who had been offered testing. We identified a fundamental mismatch between the information provided by genetic counselors and the information desired and meaningful to patients. Several components of the communication that contributed to this mismatch and often resulted in ineffective communication included: (1) too much information; (2) complex terminology and conceptually difficult presentation of information; (3) information perceived as not relevant by the patient; (4) unintentional inhibition of patient engagement and question-asking; (5) vague discussions of screening and prevention recommendations. To address these communication barriers, we adapted from other fields of Medicine to the genetic counseling context and pilot tested evidence-based strategies for effective communication with limited literacy patients. Our findings indicate a need to transform the standard model of hereditary cancer risk communication. The increasing access of diverse populations to genetic services, high rates of limited health literacy in the US, and growing complexity of genetic information have created a perfect storm. If not directly addressed, this convergence can be expected to exacerbate health disparities in the genomic age.

Abstract
Extracorporeal Shock Wave Therapy (ESWT), after its first medical application in the urological field for lithotripsy, nowadays represents a valid therapeutical tool also for many musculoskeletal diseases, as well as for regenerative medicine applications. This is possible thanks to its mechanisms of action, which in the non-urological field are not related to mechanical disruption (as for renal stones), but rather to the capacity, by mechanotransduction, to induce neoangiogenesis, osteogenesis and to improve local tissue trophism, regeneration and remodeling, through stem cell stimulation. On the basis of these biological assumptions, it becomes clear that ESWT can represent a valid therapeutic tool also for all those pathological conditions that derive from musculoskeletal trauma, and are characterized by tissue loss and/or delayed healing and regeneration (mainly bone and skin, but not only). As a safe, repeatable and noninvasive therapy, in many cases it can represent a firstline therapeutic option, as an alternative to surgery (for example, in bone and skin healing disorders), or in combination with some other treatment options. It is hoped that with its use in daily practice also the muscleskeletal field will grow, not only for standard indications, but also in posttraumatic sequelae, in order to improve recovery and shorten healing time, with undoubted advantages for the patients and lower health service expenses.

Abstract
BACKGROUND The incidence of bloodstream infection (BSI) varies according to the transplanted organ. Mortality can be as high as 24%, with a significant impact on graft survival. Transplantation is a risk factor for multidrug-resistant (MDR) organisms, but comparison with a non-transplanted population in a single large cohort has not been described. METHODS This is a prospective nationwide study (16 centers) reporting data on 2364 monomicrobial nosocomial BSIs, comparing 83 episodes in solid organ transplant patients with 2447 BSIs occurring in the general hospital population. RESULTS The prevalence of groups of infecting organisms (gram-positive, gram-negative, and fungi) was similar between transplant patients and the general population and a similar crude mortality rate was observed (34.9% in transplant vs. 43.3% in non-transplant patients). Staphylococcus aureus was the single most frequently isolated organism in both groups, and Acinetobacter species was more frequently isolated in the general population. Regarding MDR organisms, Klebsiella species, and Enterobacter species resistant to cefepime, as well as Acinetobacter species resistant to meropenem, were significantly more frequent in transplant patients. CONCLUSION Antimicrobial resistance is higher, particularly among gram-negative bacteria in the transplant population, although the overall mortality rate between transplant and non-transplant patients with nosocomial BSI is similar.

Abstract
Background: Nab-paclitaxel and gemcitabine have demonstrated a survival benefit over gemcitabine alone in advanced pancreatic cancer (PDA). This study aimed to investigate the clinical, biological, and imaging effects of the regimen in patients with operable PDA. Methods: Patients with operable PDA received two cycles of nab-paclitaxel and gemcitabine before surgical resection. FDG-PET and CA19.9 tumour marker levels were used to measure clinical activity. Effects on tumour stroma were determined by endoscopic ultrasound (EUS) elastography. The collagen content and architecture as well as density of cancer-associated fibroblasts (CAFs) were determined in the resected surgical specimen and compared with a group of untreated and treated with conventional chemoradiation therapy controls. A co-clinical study in a mouse model of PDA was conducted to differentiate between the effects of nab-paclitaxel and gemcitabine. Results: A total of 16 patients were enrolled. Treatment resulted in significant antitumour effects with 50% of patients achieving a >75% decrease in circulating CA19.9 tumour marker and a response by FDG-PET. There was also a significant decrement in tumour stiffness as measured by EUS elastography. Seven of 12 patients who completed treatment and were operated had major pathological regressions. Analysis of residual tumours showed a marked disorganised collagen with a very low density of CAF, which was not observed in the untreated or conventionally treated control groups. The preclinical co-clinical study showed that these effects were specific of nab-paclitaxel and not gemcitabine. Conclusion: These data suggest that nab-paclitaxel and gemcitabine decreases CAF content inducing a marked alteration in cancer stroma that results in tumour softening. This regimen should be studied in patients with operable PDA.

Abstract
We characterized the underlying mechanisms by which glutathione (GSH)-enhanced natural killer (NK) cells inhibit the growth of Mycobacterium tuberculosis (M. tb) inside human monocytes. We observed that in healthy individuals, treatment of NK cells with N-acetyl cysteine (NAC), a GSH prodrug in conjunction with cytokines such as interleukin (IL)-2 + IL-12, resulted in enhanced expression of NK cytotoxic ligands (FasL and CD40L) with concomitant stasis in the intracellular growth of M. tb. Neutralization of FasL and CD40L in IL-2 + IL-12 + NAC-treated NK cells resulted in abrogation in the growth inhibition of M. tb inside monocytes. Importantly, we observed that the levels of GSH are decreased significantly in NK cells derived from individuals with HIV infection compared to healthy subjects, and this decrease correlated with a several-fold increase in the growth of M. tb inside monocytes. This study describes a novel innate defence mechanism adopted by NK cells to control M. tb infection.

Abstract
BACKGROUND Identification of low-income women with the rare but serious risk of hereditary cancer and their referral to appropriate services presents an important public health challenge. We report the results of formative research to reach thousands of women for efficient identification of those at high risk and expedient access to free genetic services. External validity is maximized by emphasizing intervention fit with the two end-user organizations who must connect to make this possible. This study phase informed the design of a subsequent randomized controlled trial. METHODS We conducted a randomized controlled pilot study (n = 38) to compare two intervention models for feasibility and impact. The main outcome was receipt of genetic counseling during a two-month intervention period. Model 1 was based on the usual outcall protocol of an academic hospital genetic risk program, and Model 2 drew on the screening and referral procedures of a statewide toll-free phone line through which large numbers of high-risk women can be identified. In Model 1, the risk program proactively calls patients to schedule genetic counseling; for Model 2, women are notified of their eligibility for counseling and make the call themselves. We also developed and pretested a family history screener for administration by phone to identify women appropriate for genetic counseling. RESULTS There was no statistically significant difference in receipt of genetic counseling between women randomized to Model 1 (3/18) compared with Model 2 (3/20) during the intervention period. However, when unresponsive women in Model 2 were called after 2 months, 7 more obtained counseling; 4 women from Model 1 were also counseled after the intervention. Thus, the intervention model that closely aligned with the risk program's outcall to high-risk women was found to be feasible and brought more low-income women to free genetic counseling. Our screener was easy to administer by phone and appeared to identify high-risk callers effectively. The model and screener are now in use in the main trial to test the effectiveness of this screening and referral intervention. A validation analysis of the screener is also underway. CONCLUSION Identification of intervention strategies and tools, and their systematic comparison for impact and efficiency in the context where they will ultimately be used are critical elements of practice-based research.

Abstract
Delirium is an acute or subacute syndrome characterized by a fluctuating global disorder of cognition, impairment of attention and awareness, disorganization of thought and speech, perceptual disturbances, hallucinations, as well as hypo or hyperactivity.We present a case report of a 76-year-old woman who developed disorientation, lack of familiar recognition and functional impairment, three days before admission. She was admitted to a Medicine Department and submitted to several laboratory and imaging studies.During this period she presented attention, consciousness fluctuations and agitation that required several treatments, including neuroleptics. Like these symptoms were linked to an important life even that triggered reactive depression, she was transferred to a psychiatric ward. Progressively her clinical state worsened, she became permanently bedridden and was observed by Neurology. She presented moderate to severe parkinsonian signs, namely akinesia and rigidity, predominantly on her left side. Reviewing her clinical past, she had suffered these symptoms during the two years before this episode (apathy, small stepped gait, flexed posture, and left hand rest tremor). Treatment with antiparkinsonic drugs produced a dramatic improvement in the patient’s mental and physical status. A I-Ioflupane-SPECT (DaTscan) confirmed striatal presynaptic dopaminergic degeneration, more on the right side, which was the proof of the presence of a degenerative parkinsonian syndrome.The present clinical case shows Delirium with degenerative Parkinsonism comorbidity, worsened by the use of neuroleptics. We emphasize the importance previously undiagnosed Parkinsonism in old age which is highlighted by usefulness of dopamine transporter imaging in this scenery.

Abstract
miR-21 is a microRNA (miRNA) frequently overexpressed in human cancers. Here we show that miR-21 is upregulated both in vitro and in vivo by oncogenic Ras, thus linking this miRNA to one of the most frequently activated oncogenes in human cancers. Ras regulation of miR-21 occurs with a delayed kinetic and requires at least two Ras downstream pathways. A screen of human thyroid cancers and non-small-cell lung cancers for the expression of miR-21 reveals that it is overexpressed mainly in anaplastic thyroid carcinomas, the most aggressive form of thyroid cancer, whereas in lung its overexpression appears to be inversely correlated with tumor progression. We also show that a LNA directed against miR-21 slows down tumor growth in mice. Consistently, a search for mRNAs downregulated by miR-21 shows an enrichment for mRNAs encoding cell cycle checkpoints regulators, suggesting an important role for miR-21 in oncogenic Ras-induced cell proliferation.

Abstract
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05 GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.
