Abstract
BACKGROUND Ailments such as diarrhoea and antibiotic-associated gut symptoms are generally self-managed using probiotics. Real-world data on reasons behind self-medication with over-the-counter (OTC) products and patient-reported outcomes can be investigated strategically by the pharmacists. OBJECTIVE This study evaluates the use of Bacillus clausii (Enterogermina®) at the Italian community pharmacies among self-medicating patients, their treatment habits and perceived benefits. DESIGN This is a multicentre, prospective, non-interventional study which included two visits [at screening (T0) and end of the study (T1) when symptoms had subsided, ≤ 30 days from T0]. Patients who were already inclined to buy B. clausii were enrolled and instructed to complete a questionnaire at T0 and T1. The primary objective was to evaluate the reasons for taking B. clausii. Secondary objectives assessed treatment duration, perceived effectiveness, quality of life (QoL), treatment satisfaction and safety outcomes. RESULTS Overall, 268 patients were enrolled; 99.6% of them were evaluated at T0 and 97.4% at T1, and safety was evaluated in 97.8% who had ≥ 1 dose of B. clausii. At T0, mean age was 50.7 years and majority were females (62.2%). In the interview, main reason stated for using B. clausii at T0 was diarrhoea (56.93%), followed by other gastrointestinal symptoms. Treatment duration was shorter in those with diarrhoea or abdominal pain versus those with constipation or abdominal tension. More than 90% perceived their symptoms to have improved or improved very much. Overall QoL improved in all the aspects measured. Treatment satisfaction was reported by nearly 90% of patients as satisfied, very satisfied or extremely satisfied. No adverse events were reported. CONCLUSION This is the first pharmacy-based study in Italy that evaluated the real-world usage of an OTC probiotic containing B. clausii among self-medicating adults. Diarrhoea was the most common reason for use, with high-level of perceived effectiveness and patient satisfaction with B. clausii.

Abstract
Introduction Probiotics are living microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Adequate number of living microbes, the presence of specific microorganisms, and their survival in the gastrointestinal (GI) environment are important to achieve desired health benefits of probiotic products. In this in vitro study, 21 leading probiotic formulations commercialized worldwide were evaluated for their microbial content and survivability in simulated GI conditions. Methods Plate-count method was used to determine the amount of living microbes contained in the products. Culture-dependent Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry and culture-independent metagenomic analysis through 16S and 18S rDNA sequencing were applied in combination for species identification. To estimate the potential survivability of the microorganisms contained in the products in the harsh GI environment, an in vitro model composed of different simulated gastric and intestinal fluids was adopted. Results The majority of the tested probiotic products were concordant with the labels in terms of number of viable microbes and contained probiotic species. However, one product included fewer viable microbes than those displayed on the label, one product contained two species that were not declared, and another product lacked one of the labeled probiotic strains. Survivability in simulated acidic and alkaline GI fluids was highly variable depending on the composition of the products. The microorganisms contained in four products survived in both acidic and alkaline environments. For one of these products, microorganisms also appeared to grow in the alkaline environment. Conclusion This in vitro study demonstrates that most globally commercialized probiotic products are consistent with the claims described on their labels with respect to the number and species of the contained microbes. Evaluated probiotics generally performed well in survivability tests, although viability of microbes in simulated gastric and intestinal environments showed large variability. Although the results obtained in this study indicate a good quality of the tested formulations, it is important to stress that stringent quality controls of probiotic products should always be performed to provide optimal health benefits for the host.

Abstract
The U-wave's electrophysiological origin remains unknown and is subject to debate. It is rarely used for diagnosis in clinical practice. The aim of this study was to review new information regarding the U-wave. Further to present the proposed theories behind the U-wave's origin along with potential pathophysiologic and prognostic implications related to its presence, polarity and morphology. METHOD Literature searches were conducted to retrieve publications related to the electrocardiogram U-wave in the literature database Embase. RESULTS The review of the literature revealed the following major theories that will be discussed; late depolarisation, delayed or prolonged repolarisation, electro-mechanical stretch and IK1 dependent intrinsic potential differences in the terminal part of the action potential. Various pathologic conditions were found to correlate with the presence and properties of the U-wave, such as its amplitude and polarity. Abnormal U-waves can, for example, be observed in coronary artery disease with ongoing myocardial ischemia or infarction, ventricular hypertrophy, congenital heart disease, primary cardiomyopathy and valvular defects. Negative U-waves are highly specific for the presence of heart diseases. Concordantly negative T- and U-waves are especially associated with cardiac disease. Patients with negative U-waves tend to have higher blood pressure and history of hypertension, higher heart rate, cardiac disease and left ventricular hypertrophy compared to subjects with normal U-waves. Negative U-waves have been found to be associated with increased risk of all-cause mortality, cardiac death and cardiac hospitalisation in men. CONCLUSIONS The origin of the U-wave is still not established. U-wave diagnostics may reveal cardiac disorders and the cardiovascular prognosis. Including the U-wave characteristics in the clinical ECG assessment may be useful.

Abstract
Registration of dynamic CT image sequences is a crucial preprocessing step for clinical evaluation of multiple physiological determinants in the heart such as global and regional myocardial perfusion. In this work, we present a deformable deep learning-based image registration method for quantitative myocardial perfusion CT examinations, which in contrast to previous approaches, takes into account some unique challenges such as low image quality with less accurate anatomical landmarks, dynamic changes of contrast agent concentration in the heart chambers and tissue, and misalignment caused by cardiac stress, respiration, and patient motion. The introduced method uses a recursive cascade network with a ventricle segmentation module, and a novel loss function that accounts for local contrast changes over time. It was trained and validated on a dataset of n = 118 patients with known or suspected coronary artery disease and/or aortic valve insufficiency. Our results demonstrate that the proposed method is capable of registering dynamic cardiac perfusion sequences by reducing local tissue displacements of the left ventricle (LV), whereas contrast changes do not affect the registration and image quality, in particular the absolute CT (HU) values of the entire CT sequence. In addition, the deep learning-based approach presented reveals a short processing time of a few seconds compared to conventional image registration methods, demonstrating its application potential for quantitative CT myocardial perfusion measurements in daily clinical routine.

Abstract
Some epigenetic information can be transmitted between generations without changes in the underlying DNA sequence. Changes in epigenetic regulators, termed epimutations, can occur spontaneously and be propagated in populations in a manner reminiscent of DNA mutations. Small RNA-based epimutations occur in C. elegans and persist for around 3-5 generations on average. Here, we explored whether chromatin states also undergo spontaneous change and whether this could be a potential alternative mechanism for transgenerational inheritance of gene expression changes. We compared the chromatin and gene expression profiles at matched time points from three independent lineages of C. elegans propagated at minimal population size. Spontaneous changes in chromatin occurred in around 1% of regulatory regions each generation. Some were heritable epimutations and were significantly enriched for heritable changes in expression of nearby protein-coding genes. Most chromatin-based epimutations were short-lived but a subset had longer duration. Genes subject to long-lived epimutations were enriched for multiple components of xenobiotic response pathways. This points to a possible role for epimutations in adaptation to environmental stressors.

Abstract
Mupirocin-based decolonization of Staphylococcus aureus carriers undergoing haemodialysis is not widely implemented due to concerns of mupirocin resistance. In our haemodialysis unit, a strategy combining universal S. aureus screening with targeted mupirocin-based decolonization has been introduced two decades ago. In this study of haemodialysis patients, mupirocin resistance was assessed in blood and colonizing S. aureus isolates during two periods. Mupirocin resistance in S. aureus was infrequent in both blood and colonizing isolates. Furthermore, in the years 2003-2021, a decreasing trend of the annual rate of S. aureus bloodstream infections was observed. Targeted mupirocin-based decolonization of S. aureus carriers undergoing haemodialysis is a sustainable measure for preventing healthcare-associated infections.

Abstract
Aneuploidy in preimplantation embryos is a major cause of human reproductive failure. Unlike uniformly aneuploid embryos, embryos diagnosed as diploid-aneuploid mosaics after preimplantation genetic testing for aneuploidy (PGT-A) can develop into healthy infants. However, the reason why these embryos achieve full reproductive competence needs further research. Current RNA sequencing techniques allow for the investigation of the human preimplantation transcriptome, providing new insights into the molecular mechanisms of embryo development. In this prospective study, using euploid embryo gene expression as a control, we compared the transcriptome profiles of inner cell mass and trophectoderm samples from blastocysts with different levels of chromosomal mosaicism. A total of 25 samples were analyzed from 14 blastocysts with previous PGT-A diagnosis, including five low-level mosaic embryos and four high-level mosaic embryos. Global gene expression profiles visualized in cluster heatmaps were correlated with the original PGT-A diagnosis. In addition, gene expression distance based on the number of differentially expressed genes increased with the mosaic level, compared to euploid controls. Pathways involving apoptosis, mitosis, protein degradation, metabolism, and mitochondrial energy production were among the most deregulated within mosaic embryos. Retrospective analysis of the duration of blastomere cell cycles in mosaic embryos revealed several mitotic delays compared to euploid controls, providing additional evidence of the mosaic status. Overall, these findings suggest that embryos with mosaic results are not simply a misdiagnosis by-product, but may also have a genuine molecular identity that is compatible with their reproductive potential.

Abstract
A child with early failure of a Fontan circulation was listed for cardiac transplantation and then developed a subhepatic abscess. Surgical drainage was deemed necessary after the failure of an attempted percutaneous procedure. Following a multidisciplinary discussion, a laparoscopic technique was chosen to optimise postoperative recovery. To our knowledge, the literature does not describe any case of laparoscopic surgery in a patient with a failing Fontan circulation. This case report highlights the physiological variations involved with this management strategy, discusses the implications and risks, and offers some recommendations.

Abstract
OBJECTIVES Current irritable bowel syndrome (IBS) treatments have limited efficacy and probiotics like Bacillus clausii (B. clausii) were found to be effective in the management of several gastrointestinal disorders. This phase III trial assessed the efficacy and safety of adding B. clausii (four strains: O/C, N/R, SIN, T), versus placebo, to conventional treatment of pediatric IBS in Mexico. METHODS Patients aged 6-17 years 11 months with IBS (Rome IV) for at least 2 months were randomized to receive either B. clausii (oral suspension, total dose 4 billion spores/day) or placebo once daily for 8 weeks. All patients also received conventional treatment. The primary endpoint was the difference in the proportion of patients with clinical improvements at Week 8 (Global Assessment Questions [GAQ]). Secondary endpoints included responders by Subject's Global Assessment of Relief for Children with IBS (SGARC); number/consistency of stools; abdominal distention/bloating; abdominal pain/intensity; and IBS behavior. RESULTS 73.6% (95% confidence interval [CI] 67.3-80.0; B. clausii n = 129) and 78.5% (95% CI 72.5-84.4; placebo n = 130) of patients had symptom improvement (p = 0.8182). For Week 8 SGARC, 19.2% (B. clausii) and 20.9% (placebo) reported complete symptom relief. Stool evaluations, bloating, abdominal pain/intensity, and IBS behavior were similar between groups. Both treatments were well tolerated. CONCLUSION No significant differences in efficacy between B. clausii and placebo were demonstrated in addition to conventional treatment. The sample size calculation was based on an expected placebo/conventional treatment response of 30-40%. However, the actual treatment response observed was 80% and, thus, a study with larger population would be warranted. In addition, this study was conducted during the COVID-19 pandemic, when such controlled social conditions may have resulted in better diet, greater family stability, less psychological stress, and lower risk of infections exacerbating IBS, thereby improving symptoms in both groups.

Abstract
Abstract
Introduction/Objective
Extranodal marginal zone lymphoma (MZL) is a rare indolent tumor with the potential of recurrence and systemic spread. Thyroid involvement is infrequently reported, and generally seen in the context of Hashimoto thyroiditis. Additionally, amyloid deposition is an exceptional complication of extranodal MZL. We report an unusual case of a 65-year-old woman with a rapidly growing symptomatic nodule of the right thyroid lobe and a previous inconclusive FNA showing benign lymphoid tissue. She was taken to the OR for diagnostic right thyroid lobectomy with neck level 6 dissection.
Methods/Case Report
The specimen was sent for histologic evaluation, and showed thyroid with marked amyloid deposition, highlighted by Congo Red special stain, distorting normal architecture. Additionally, significant small atypical lymphoid infiltrate was present. Neoplastic lymphocytes were positive for CD20, PAX5 and CD43. Kappa light chain restriction by kappa ISH stain indicated monoclonality. Conversely, CD138, CD10, BCL6 and CyclinD were negative. Ki-67 demonstrated a 15-20% proliferation index. The germinal centers of the secondary follicles demonstrated diminished CD10 and BCL-6 consistent with follicular colonization by neoplastic lymphocytes. One of the regional lymph nodes displayed involvement by lymphoma with amyloid deposition. Medullary carcinoma of the thyroid was ruled out on the basis of incompatible histologic and immunohistochemical profile.
Results (if a Case Study enter NA)
NA
Conclusion
While Medullary carcinoma and amyloid goiter are among the top differentials for extensive amyloid deposition in the thyroid gland, we illustrate the need for judicious review of clinical history and careful consideration of immunohistochemistry workup to establish the unusual diagnosis of extranodal MZL of the thyroid with extensive amyloid deposition.

Abstract
The gut microbiota is intrinsically linked to human health; disturbances in microbial homeostasis are implicated in both intestinal and extraintestinal disorders. Probiotics are "live microorganisms that, when administered in adequate amounts, confer a health benefit on the host," and many commercial preparations comprising a diverse range of species are available. While probiotics have been much researched, better understanding of the probiotic effects and applications of species such as Bacillus clausii is warranted. In this narrative literature review, we review the characteristics and mechanisms of action supporting B. clausii as a probiotic and discuss the evidence from clinical studies evaluating B. clausii probiotics for the management of a variety of gastrointestinal disorders and symptoms in children and adults. Finally, we highlight the challenges of future research and the need for more robust and diverse clinical evidence to guide physicians in the clinical application of probiotics for gastrointestinal disorders and other conditions.

Abstract
INTRODUCTION The gut microbiota affects the development of the gut immune system in early life. Perturbations to microbiota structure and composition during this period can have long-term consequences on the health of the individual, through its effects on the immune system. Research in the last few decades has shown that probiotic administration can reverse these effects in strain- and environment-specific ways. Bacillus clausii (B. clausii) has been in use for many decades as a safe and efficacious probiotic, but its mode of action has not yet been completely elucidated. AREAS COVERED In this review, we discuss how the gut immune system works, the factors that affect its functioning, and the plethora of research highlighting its role in various diseases. We also discuss the known modes of action of Bacillus probiotics, and highlight the preclinical and clinical evidence that reveal how B. clausii acts to bolster gut defense. EXPERT OPINION We anticipate that the treatment and/or prevention of dysbiosis will be central to managing human health and disease in the future. Discovering the pathophysiology of autoimmune diseases, infections, allergies, and some cancers will aid our understanding of the key role played by microbial communities in these diseases.

Abstract
BACKGROUND Nosocomial outbreaks of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are frequent despite implementation of conventional infection control measures. An outbreak investigation was undertaken using advanced genomic and statistical techniques to reconstruct likely transmission chains and assess the role of healthcare workers (HCWs) in SARS-CoV-2 transmission. METHODS A nosocomial SARS-CoV-2 outbreak in a university-affiliated rehabilitation clinic was investigated, involving patients and HCWs, with high coverage of pathogen whole-genome sequences (WGS). The time-varying reproduction number from epidemiological data (Rt) was estimated, and maximum likelihood phylogeny was used to assess genetic diversity of the pathogen. Genomic and epidemiological data were combined into a Bayesian framework to model the directionality of transmission, and a case-control study was performed to investigate risk factors for nosocomial SARS-CoV-2 acquisition in patients. FINDINGS The outbreak lasted from 14th March to 12th April 2020, and involved 37 patients (31 with WGS) and 39 employees (31 with WGS), 37 of whom were HCWs. Peak Rt was estimated to be between 2.2 and 3.6. The phylogenetic tree showed very limited genetic diversity, with 60 of 62 (96.7%) isolates forming one large cluster of identical genomes. Despite the resulting uncertainty in reconstructed transmission events, the analyses suggest that HCWs (one of whom was the index case) played an essential role in cross-transmission, with a significantly greater fraction of infections (P<2.2e-16) attributable to HCWs (70.7%) than expected given the number of HCW cases (46.7%). The excess of transmission from HCWs was higher when considering infection of patients [79.0%; 95% confidence interval (CI) 78.5-79.5%] and frail patients (Clinical Frailty Scale score >5; 82.3%; 95% CI 81.8-83.4%). Furthermore, frail patients were found to be at greater risk for nosocomial COVID-19 than other patients (adjusted odds ratio 6.94, 95% CI 2.13-22.57). INTERPRETATION This outbreak report highlights the essential role of HCWs in SARS-CoV-2 transmission dynamics in healthcare settings. Limited genetic diversity in pathogen genomes hampered the reconstruction of individual transmission events, resulting in substantial uncertainty in who infected whom. However, this study shows that despite such uncertainty, significant transmission patterns can be observed.

Abstract
Disordered eating research has long considered the negative consequences of internalizing sociocultural appearance ideals (e.g., thin ideal, muscular ideal). However, the implications of internalizing a curvy or "hourglass" body shape remains unclear. The Hourglass Body Shape Ideal Scale (HBSIS) is a new self-report questionnaire that was developed and evaluated to appropriately measure the extent women subscribe to an hourglass body shape ideal. The measure was administered to a community and undergraduate sample of women via two separate online studies. Study 1 (N = 916) provided support for the factor structure as well as the convergent and discriminant validity of the HBSIS. The HBSIS was correlated with measures of appearance orientation, overweight preoccupation, and disordered eating. HBSIS was associated with disordered eating even after controlling for age, BMI, thin ideal and muscular ideal internalization. Further, higher HBSIS scores were associated with increased likelihood of having clinical levels of disordered eating symptoms. There were no racial and ethnic group differences on HBSIS. Study 2 (N = 195) replicated the factor structure of Study 1, in addition to its convergent and discriminant validity. The HBSIS allows for more precise examination of appearance-ideal internalization, capturing a unique construct understudied within eating pathology literature.

Abstract
OBJECTIVES To perform an ergonomic intervention using the methodology of the analysis of the activity of the training process of clinical pharmacy residents in the analysis of prescriptions. METHODS The evaluation was carried out over two semesters: from May to October 2016 (first study) and from November 2016 to April 2017 (second study). The interviews and observations were conducted by an ergonomist who is an expert in this type of evaluation. The first study was based on observations of the training process and interviews at different time. The second study allowed to support pharmacists and evaluate the changes following the recommendations of the previous study. RESULTS A total of 6 and 9 residents participated in the first and second study, respectively. During the first study, 6 difficulties were raised which allowed implementation decisions. Feedback from residents on the training process was generally positive for the first part of the training but negative for the last part. The average number of fears expressed by the residents was higher at the beginning (2.9 fears) than at the end (1 fear). CONCLUSIONS The training process has been adapted to the expectations and feelings of the residents. Follow-up at the beginning and throughout the internship was essential. The next stage of this work will be to evaluate the contribution of the dashboards for monitoring clinical pharmacy skills in the new degree for hospital pharmacy.

Abstract
Dermatofibrosarcoma is the most common cutaneous sarcoma. Its surgical management is a technical challenge due to the high amount of substance loss. We explain a new technique of abdominal wall reconstruction by a reverse abdominoplasty with umbilical transposition. This new surgical technique allowed, in one time, the excision and the abdominal wall reconstruction. Functional and esthetic results are really satisfactory.

Abstract
In metastatic melanoma, with a dismal survival rate and propensity for treatment resistance and recurrence, it is critical to establish biomarkers that better predict treatment response and disease severity. The melanoma glycome, composed of complex carbohydrates termed glycans, is an under-investigated area of research, although it is gaining momentum in the cancer biomarker and therapeutics field. Novel findings suggest that glycans play a major role in influencing melanoma progression and could be exploited for prognosticating metastatic activity and/or as therapeutic targets. In this review, we discuss the role of aberrant glycosylation, particularly the specialized function of β1,6 N-acetylglucosaminyltransferase 2 (GCNT2), in melanoma pathogenesis and summarize mechanisms of GCNT2 regulation to illuminate its potential as a predictive marker and therapeutic target.

Abstract
We present a mixed-lattice atomistic kinetic Monte-Carlo algorithm (MLKMC) that integrates a rigid-lattice AKMC approach with the kinetic activation-relaxation technique (k-ART), an off-lattice/self-learning AKMC. This approach opens the door to study large and complex systems adapting the cost of identification and evaluation of transition states to the local environment. To demonstrate its capacity, MLKMC is applied to the problem of the formation of a C Cottrell atmosphere decorating a screw dislocation in α-Fe. For this system, transitions that occur near the dislocation core are searched by k-ART, while transitions occurring far from the dislocation are computed before the simulation starts using the rigid-lattice AKMC. This combination of the precision of k-ART and the speed of the rigid-lattice makes it possible to follow the onset of the C Cottrell atmosphere and to identify interesting mechanisms associated with its formation.

Abstract
microRNAs (miRNAs) are post-transcriptional regulators of gene expression and can play an important role in modulating organismal development and physiology in response to environmental stress. However, the role of miRNAs in mediating adaptation to diverse environments in natural study systems remains largely unexplored. Here, we characterized miRNAs and their expression in Poecilia mexicana, a species of small fish that inhabits both normal streams and extreme environments in the form of springs rich in toxic hydrogen sulphide (H2 S). We found that P. mexicana has a similar number of miRNA genes as other teleosts. In addition, we identified a large population of mature miRNAs that were differentially expressed between locally adapted populations in contrasting habitats, indicating that miRNAs may contribute to P. mexicana adaptation to sulphidic environments. In silico identification of differentially expressed miRNA-mRNA pairs revealed, in the sulphidic environment, the downregulation of miRNAs predicted to target mRNAs involved in sulphide detoxification and cellular homeostasis, which are pathways essential for life in H2 S-rich springs. In addition, we found that predicted targets of upregulated miRNAs act in the mitochondria (16.6% of predicted annotated targets), which is the main site of H2 S toxicity and detoxification, possibly modulating mitochondrial function. Together, the differential regulation of miRNAs between these natural populations suggests that miRNAs may be involved in H2 S adaptation by promoting functions needed for survival and reducing functions affected by H2 S. This study lays the groundwork for further research to directly demonstrate the role of miRNAs in adaptation to H2 S. Overall, this study provides a critical stepping-stone towards a comprehensive understanding of the regulatory mechanisms underlying the adaptive variation in gene expression in a natural system.

Abstract
To study the contribution of yeasts to the formation of terpene derivatives during winemaking, a dispersive liquid-liquid microextraction gas chromatography mass spectrometry method was developed for the quantitation of terpenes in white wines, synthetic wine, and a fermented synthetic medium. A mixture of acetone (disperser solvent) and dichloromethane (extraction solvent) was added to 5 mL of sample. The proposed method showed no matrix effect, good linearity in the enological range (from 10 to 200 μg/L), good recovery, and satisfactory inter- and intraday reproducibilities (below 20 and 15% of the relative standard deviation). This sample preparation technique is very interesting for high-throughput studies and economic and environmental reasons because it is fast and easy to operate with high enrichment and consumes a low volume of organic solvents. This method was applied to explore the capacities of 40 yeast strains to produce terpene compounds during fermentation of Chardonnay and Ugni Blanc musts as well as in a synthetic medium. Interestingly, most of the studied compounds were detected and quantified in the resulting wines. This study shows that yeast strains can intrinsically produce terpene derivatives under enological conditions and also highlights the differences between the de novo biosynthesis of terpenes and their precursor-linked production.

Abstract
BACKGROUND In the cartilaginous nose, classical surgical anatomy describes 2 triangular upper lateral cartilages (ULCs) framing the lateral sides of the mid-third of the nasal pyramid, which articulate with to the superior edge of the quadrangular cartilage (QC) of the nasal septum. This anatomic arrangement in 3 distinct cartilage parts is, however, controversial. OBJECTIVE The present study aimed to describe the articulation between the ULCs and the QC, avoiding dissection artefacts. MATERIALS AND METHODS Six nasal pyramids were taken in monobloc from fresh cadavers and imaged on micro-MRI with 0.4mm slice thickness. Images were interpreted jointly by 2 head and neck surgeons and a radiologist. RESULTS The cartilage skeleton supporting the mid-third of the nasal dorsum in all specimens presented as 2 septal plates backing onto the midline and curving on either side to form a continuous dome under the inferior aspect of the piriform aperture. CONCLUSION Like the alar cartilages framing the tip of the nose, there are two continuous septolateral cartilages (SLCs) framing the mid-third of the nasal pyramid, likewise showing 2 cruras, medial and lateral, joined in a dome. The SLCs (also known as triangular cartilages) thus cannot be separated as 2 individual anatomic structures. These findings are in line with the shared embryological origin of all the elements composing the fibrocartilaginous nose in evo-devo theory.

Abstract
Abstract
Background
Detection of prior myocardial infarction (MI) may inform arrhythmia treatment and prognosis, yet cardiac imaging is resource intensive. ECG Q-wave analysis is quick and inexpensive but has poor accuracy for assessing prior MI.
Purpose
To evaluate the ability of a deep neural network (DNN) trained on the surface ECG to identify patients with prior MI.
Methods
We assessed 608 well-characterized patients (61.4±14.5 years, 31.2% female) at 2 academic centers. From one 12-lead ECG, median beats were calculated in 3 orthogonal planes (X, Y, Z; Fig. 1A) and used to train a DNN to identify a history of prior MI. Accuracy was compared to manual assessment of pathologic Q waves, defined as a deflection >25% of the subsequent R wave, >40ms in width, and >0.2mV amplitude in 1 of 3 ECG planes.
Results
Of 608 patients, 175 had history of MI (28.7%). The DNN outperformed the accuracy of pathologic Q waves. In training, DNN converged to >98% accuracy and in testing, its accuracy was 71±5% (Fig. 1B) (k=5-fold cross validation). This outperformed the 62% accuracy of pathologic Q waves in this study (red dotted line, Fig. 1B). In the validation cohort, DNN provided an area under the receiver operating characteristics curve of 0.730 (Fig. 1C).
Conclusion
Deep learning of a 12-lead ECG can identify features of prior myocardial injury more accurately than Q-wave analysis. In attempting to improve these results further, studies should explain what inputs weighted DNN decisions, and identify those that reflect abnormalities detectable clinically or on imaging.

Abstract
Abstract
Background
The diagnosis of ARVC is complex and challenging requiring multiple investigational tools, most of which include the demonstration of depolarization/conduction abnormalities, described in recent HRS consensus documents 2019. A simple and user friendly diagnostic tool is warranted.
Purpose
The purpose of our study was therefore to explore whether the analysis of QRS dispersion obtained from 252-leads recorded by a Body Surface Mapping (BSM) system can be used to identify ARVC patients as compared to the traditional ECG criteria including QRS dispersion measured by conventional 12 lead surface ECG.
Methods
12 definite ARVC patients (10/12 with known pathogenic mutation) (Group 1) and 8 healthy family members tested negative for the family mutation served as controls (Group 0), were included. All patients underwent 12-lead ECG (50mm/sec), Signal-averaged ECG for late potentials and 252 lead BSM recordings. The QRS duration was measured in each of the 12 ECG leads manually with digital caliper. The QRS duration from the BSM leads were manually analyzed in Matlab by two observers unaware of the diagnosis. For each lead, the mean value of three randomly chosen beats was calculated. The QRS dispersion was calculated as the difference between the minimum and maximum value for both the 12 lead ECG and the BSM recordings.
Results
The mean age was 49,6 and 38,8 years in ARVC patients and controls, respectively. The number of males in the two groups were 8/12 and 5/8, respectively. Epsilon waves and Terminal Activation Duration (TAD) >55msec were detected in 6/12 and 8/12 ARVC patients, respectively, but in no controls. Late potentials were detected in 11/12 ARVC patients and in 2 controls. The QRS duration and QTc duration was not statistically different in the two Groups.
The ECG-QRS dispersion was significantly more pronounced in Group 1 (42 ms ± 15, range 20–70 ms) than in Group 0 (26 ms ± 8, range 16–36 ms) (p=0.013). The BSM-QRS dispersion was significantly longer in Group 1 (68 ms ± 17, range 29–90ms) than in Group 0 (30 ms ± 7, range 22–41ms) (p=0.001). Only one ARVC patient had a BSM-QRS dispersion <50 msec, whereas none of the controls had a QRS dispersion over 50 msec (Fig. 1).
Conclusion
BSM-QRS dispersion, specifically using the cut off <50 ms, can potentially be a more sensitive and specific method than other ECG related techniques for diagnosing ARVC patients versus non-ARVC patients. Larger patient cohorts and further studies are required to confirm our findings.

Abstract
Abstract
Background
Repolarization abnormalities have a central role on the diagnosis of ARVC according to recent HRS consensus document from 2019 stating that T wave inversion in the right precordial leads is a major criteria if it appears in V1-V3 or a minor criteria if it appears in only V1-V2.
Purpose
The aim of our study was to investigate whether repolarization patterns as recorded by a Body Surface Mapping (BSM) system consisting of a vest with 252 ECG leads, could differentiate ARVC patients and even gene carriers from normal individuals. Our hypothesis is that the method can potentially identify repolarization disturbances earlier or better than conventional 12-lead ECG.
Method
12 definite ARVC patients, 20 healthy gene carriers and 8 family members who tested negative for the family mutation (controls) were included. All patients underwent 12-lead ECG, including right precordial leads (V4R) and BSM recordings. Repolarization (T-wave polarity and concordance with QRS complex vector) was analyzed qualitatively in all BSM recordings, the results of which were displayed on a color code map (fig.1).
Results
The mean age was 49.6, 43.6 and 38.8 years in ARVC patients, healthy gene carriers and controls, respectively. The number of males in the three groups were 8/12, 8/20 and 5/8, respectively.
All 8 controls had similar repolarization patterns with negative and concordant T waves on the right back panel, and T waves that successively changed from negative concordant (green) to positive disconcordant (red) and finally positive concordant (blue) on the left front panel (pattern 1). All 12 ARVC patients had different repolarization patterns as compared to the controls. Two of these patients had no apparent repolarization changes on conventional 12 lead ECG. The pattern type 2 repolarization, as defined by same pattern as the controls at the right back panel but different pattern at the front left panel was seen in 3/12 ARVC patients. The remaining 9 ARVC patients had different repolarization patterns both on the front and on the back panel (pattern 3). Among gene carriers, 15 had a normal repolarization pattern (pattern 1) and 5 demonstrated an abnormal repolarization pattern (4 had pattern type 2 and one pattern 3) despite normal surface ECG.
Conclusions
Using BSM recordings, abnormal repolarization patterns can be detected in all ARVC patients, even in those without repolarization changes on conventional surface ECG. The observation that 25% of gene carriers had divergent repolarization patterns, may indicate an early stage of the disease, and be used as an early diagnostic marker of the disease. Further and larger studies are warranted to confirm these observations.

Abstract
Helminths are parasitic worms that constitute a major public health problem. Conventional analytical techniques to evaluate helminth eggs in environmental samples rely on different steps, namely sedimentation, filtration, centrifugation, and flotation, to separate the eggs from a variety of particles and concentrate them in a pellet for direct observation under an optical microscope. To improve this process, a new approach was implemented in which various image processing algorithms were developed and implemented by a Helminth Egg Automatic Detector (HEAD). This allowed identification and quantification of pathogenic helminth eggs of global medical importance and it was found to be useful for relatively clean wastewater samples. After the initial version, two improvements were developed: first, a texture verification process that reduced the number of false positive results; and second, the establishment of the optimal thresholds (morphology and texture) for each helminth egg species. This second implementation, which was found to improve on the results of the former, was developed with the objective of using free software as a platform for the system. This does not require the purchase of a license, unlike the previous version that required a Mathworks® license to run. After an internal statistical verification of the system was carried out, trials in internationally recognized microbiology laboratories were performed with the aim of reinforcing software training and developing a web-based system able to receive images and perform the analysis throughout a web service. Once completed, these improvements represented a useful and cheap tool that could be used by environmental monitoring facilities and laboratories throughout the world; this tool is capable of identifying and quantifying different species of helminth eggs in otherwise difficult environmental samples: wastewater, soil, biosolids, excreta, and sludge, with a sensitivity and specificity for the TensorFlow (TF) model in the web service values of 96.82% and 97.96% respectively. Additionally, in the case of Ascaris, it may even differentiate between fertile and non-fertile eggs.

Abstract
Research links the built environment to health outcomes, but little is known about how this affects quality of life (QOL) of African American breast cancer patients, especially those residing in disadvantaged neighborhoods. Using latent trajectory models, we examined whether the built environment using Google Street View was associated with changes in QOL over a 2-year follow-up in 228 newly diagnosed African American breast cancer patients. We measured QOL using the RAND 36-Item Health Survey subscales. After adjusting for covariates, improvement in emotional well-being and pain over time was greater for women living on streets with low-quality (vs. high-quality) sidewalks.

Abstract
Simulation has become increasingly important in surgical teaching in recent years and the French National Authority for Health (HAS) recently underlined the goal and ethical priority: "never the first time on the patient". Simulation programs have been tested and validated for laparotomy and for laparoscopy, but there is not yet a validated program specific for robotic surgery. Due to substantial advances in this new technology, we have developed a program in Nancy dedicated to outside-the-operating room (OR) teaching of robotic surgery using the Da Vinci robot. This teaching is based on a combined program of theoretical teaching (e-learning) and learning of practical skills using virtual simulators (DV-Trainer®, Robotic Mentor®, DVSS®), mechanical simulators (Dome, Applied® abdominal simulators), microsurgery and wet lab using ex vivo animal organs, anesthetized animals, and cadavers. This program also emphasizes team training. The course is intended for residents in surgical training and is integrated into the specialized study diploma (DES) program for Visceral and Digestive Surgery; it also can be used by qualified surgeons who can integrate it with the Inter-University Diploma (DIU) in General Robotic Surgery for basic techniques and also for DIUs in other surgical specialties (digestive and gynecologic surgery) for robotic uses within their specialty. These courses are based on the concept of step-by-step skills acquisition and verification allowing a transition to safe clinical activity.

Abstract
Abstract
Background
Calcific aortic valve disease is the 2nd most frequent cause of open heart surgery. The valve interstitial cells (VIC) are crucial for calcification. SNF472 (a derivative of phytic acid) is a calcification inhibitor currently in clinical development for the treatment of cardiovascular calcification (Phase 2 CaLIPSO trial, EudraCT 2016–002834–59). SNF472 has been shown to inhibit vascular calcification in several preclinical models.
Purpose
1. Establish a new model of calcification in cultured human VIC; 2. Investigate whether SNF472 would inhibit calcification in this model, and 3. Study if SNF472 might inhibit ongoing calcification processes.
Methods
Healthy and calcified aortic valves were obtained from heart transplant recipients and patients undergoing aortic valve replacement due to calcific valve disease, respectively. VIC were isolated and seeded in basic growth medium, osteogenic differentiation medium (Osteodiff) alone, and with addition of different concentrations of SNF472. The following series of studies were performed: 1. VIC from healthy and calcified valves were cultured for three weeks with Osteodiff; 2. VIC from calcified valves were cultured for 3 weeks in Osteodiff media with 0, 1, 3, 10, 30, or 100 μM SNF472; 3. VIC from calcified valves were cultured for 3 weeks in Osteodiff media in total, but after 1 or 2 weeks 30 or 100 μM SNF472 was added to the cultures (n=8). Calcification was visualized by Alzarin Red staining and quantified by spectrophotometry. Statistics analysis was performed nonparametric One-Way ANOVA (Friedman and Kruskal–Wallis tests) with Dunn's post-test.
Results
Calcification was found to be 30% stronger in cultures of VIC from calcified valves as compared to cultured VIC from healthy valves (p=0.03). SNF472 successfully inhibited VIC calcification in a dose-dependent manner. SNF472 concentrations of 1, and 3 μM inhibited calcification by 7% (not significant) and 66% (p=0.08) respectively. Concentrations of 10, 30, and 100 μM completely inhibited calcification. 30 and 100 μM of SNF472 added after 1 week reduced ongoing calcification by 84% (p<0.01) and 100% (p<0.01) respectively. When given after 2 weeks of ongoing calcification non-significant inhibition was still observed (21 and 30%, respectively).
Conclusions
VIC from calcified valves have a more pro-calcification phenotype than VIC from healthy valves. SNF472 is able to inhibit the development VIC calcification in vitro. By early intervention SNF472 is also able to stop the progression of ongoing calcification. SNF472 shows to be a promising therapy to treat heart valve calcification.

Abstract
Plants possess a large set of transcription factors both involved in the control of plant development or in plant stress responses coordination. We previously identified PRR2, a Pseudo-Response Regulator, as a plant-specific CML-interacting partner. We reported that PRR2 acts as a positive actor of plant defense by regulating the production of antimicrobial compounds. Here, we report new data on the interaction between PRR2 and transcription factors belonging to the Teosinte branched Cycloidea and PCF (TCP) family. TCPs have been described to be involved in plant development and immunity. We evaluated the ability of PRR2 to interact with seven TCPs representative of the different subclades of the family. PRR2 is able to interact with TCP13, TCP15, TCP19 and TCP20 in yeast two-hybrid system and in planta interactions were validated for TCP19 and TCP20. Transient expression in tobacco highlighted that PRR2 protein is more easily detected when co-expressed with TCP19 or TC20. This stabilization is associated with a specific sub-nuclear localization of the complex in Cajal bodies or in nuclear speckles according to the interaction of PRR2 with TCP19 or TCP20 respectively. The interaction between PRR2 and TCP19 or TCP20 would contribute to the biological function in specific nuclear compartments.

Abstract
Abstract
Background:
CNS metastases are reported in about 10 to 15%. Knowledge about the management of these patients are limited because they are excluded from clinical trials due to its poor prognosis and morbidity. In these study, we aim to describe characteristics, treatment patterns, and overall survival (OS) of patients of mBC with CNS metastases at Instituto Nacional de Cancerología de Mexico (INCan) from january 2007 to december 2015.
Methods:
We include patients with histological diagnosis of mBC and tumoral activity in the CNS (at diagnosis or during de follow-up). mBC subtype was defined using HER2 and hormone receptor (HR) status by immunohistochemistry; systemic treatment, and mortality data were used to characterize mBC with CNS involment.
Results:
During the study period, we found 1272 patients diagnosed with metastatic disease, of whom 408 had CNS disease (novo/recurrence) the median follow up was 52 months. Table 1 describes the percentage of CNS metastases by subtype, clinical characteristics at diagnosis and median OS. Almost all patients (85.6%) were candidate to holocranial radiotherapy; after that, systemic treatment varied according to the subtype of mBC; 69.1% of TN received CT (26% based on platinum); 75.3% of HER2+ received systemic treatment, all included antiher2 therapy; luminal subtype, no one were treated with endocrine therapy.

Conclusions:
HER2 positive breast cancer patients have the highest prevalence of CNS metastases, whereas luminal has the lowest. Patients with HER2+ and CNS metastases commonly receive treatment based on anti-HER2 therapy, maybe this target treatment contribute to the better survival achieved than patients with luminal or TN subtype. mBC with CNS metastases continues in the real world to be an unmet medical need.
