Abstract
OBJECTIVE We aimed to describe characteristics of patients with ATTR variant polyneuropathy (ATTRv-PN) and ATTRv-mixed and assess the real-world use and safety profile of tafamidis meglumine 20mg. METHODS Thirty-eight French hospitals were invited. Patient files were reviewed to identify clinical manifestations, diagnostic methods, and treatment compliance. RESULTS Four hundred and thirteen patients (296 ATTRv-PN, 117 ATTRv-mixed) were analyzed. Patients were predominantly male (68.0%) with a mean age of 57.2±17.2 years. Interval between first symptom(s) and diagnosis was 3.4±4.3 years. First symptoms included sensory complaints (85.9%), dysautonomia (38.5%), motor deficits (26.4%), carpal tunnel syndrome (31.5%), shortness of breath (13.3%), and unexplained weight loss (16.0%). Mini-invasive accessory salivary gland or punch skin and nerve biopsies were most common, with a performance of 78.8-100%. TTR genetic sequencing, performed in all patients, revealed 31 TTR variants. Tafamidis meglumine was initiated in 156/214 (72.9%) ATTRv-PN patients at an early disease stage. Median treatment duration was 6.00 years in ATTRv-PN and 3.42 years in ATTRv-mixed patients. Tafamidis was well tolerated, with 20 adverse events likely related to study drug among the 336 patients. CONCLUSION In France, ATTRv patients are usually identified early thanks to the national network and the help of diagnosis combining genetic testing and mini-invasive biopsies.

Abstract
In this new study, we present an intriguing development in the field of theranostics: the simplistic self-assembly of red-emissive amphiphilic porphyrin-like carbon dots (P-CDs). By harnessing their exceptional photophysical properties, we have revealed a strong candidate as the ideal photosensitizer (PS) for applications, particularly in the realm of imaging. Spanning a remarkable size average between 1-4 nm, these particles exhibit both highly stable and unparalleled emission characteristics between 650 and 715 nm in water in comparison to current carbon dots (CDs) available. Lastly, these CDs were fairly non-toxic when tested against normal human cell lines as well as were found to have favorable imaging capabilities in zebrafish embryo.

Abstract
Over time, the interest in developing stable photosensitizers (PS) which both absorb and emit light in the red region (650 and 950 nm) has gained noticeable interest. Recently, carbon dots (CDs) have become the material of focus to act as a PS due to their high extinction coefficient, low cytotoxicity, and both high photo and thermal stability. In this work, a Federal and Drug Association (FDA) approved Near Infra-Red (NIR) organic fluorophore used for photo-imaging, indocyanine green (ICG), has been explored as a precursor to develop water-soluble red emissive CDs which possess red emission at 697 nm. Furthermore, our material was found to yield favorable red-imaging capabilities of glioblastoma stem-like cells (GSCs) meanwhile boasting low toxicity. Additionally with post modifications, our CDs have been found to have selectivity towards tumors over healthy tissue as well as crossing the blood-brain barrier (BBB) in zebrafish models.

Abstract
In this work, a NIR emitting dye, p-toluenesulfonate (IR-813) was explored as a model precursor to develop red emissive carbon dots (813-CD) with solvatochromic behavior with a red-shift observed with increasing solvent polarity. The 813-CDs produced had emission peaks at 610 and 698 nm, respectively, in water with blue shifts of emission as solvent polarity decreased. Subsequently, 813-CD was synthesized with increasing nitrogen content with polyethyleneimine (PEI) to elucidate the change in band gap energy. With increased nitrogen content, the CDs produced emissions as far as 776 nm. Additionally, a CD nanocomposite polyvinylpyrrolidone (PVP) film was synthesized to assess the phenomenon of solid-state fluorescence. Furthermore, the CDs were found to have electrochemical properties to be used as an additive doping agent for PVP film coatings.

Abstract
Abstract
Background
Transthyretin amyloidosis (ATTR) is a rare and serious, systemic disease characterized by deposits of amyloid fibrils in various tissues and organs. Tafamidis meglumine is a potent and selective stabilizer of TTR, indicated since 2011 in the treatment of neurological forms of the disease. The French “Agence Nationale de Sécurité du Médicament et des produits de santé” (ANSM) granted a temporary recommendation for use (RTU) on November 28th 2018, based on ATTR-ACT, the pivotal trial results, and designed to enable use of tafamidis meglumine in ATTR cardiomyopathy (ATTR-CM) patients with NYHA I, II and III before marketing authorization. This RTU has been a unique opportunity in France to collect real world data of ATTR-CM patients treated by tafamidis meglumine.
Objective
We aimed to describe the characteristics of ATTR-CM patient treated by tafamidis in the setting of the RTU, over 2 years from November 28th 2018 to November 27th 2020.
Methods
Demographic and clinical data about the diagnosis pathway of patients included in the RTU were prospectively collected using questionnaires, as requested by ANSM to be completed by physicians at the time of tafamidis prescription. A second version of the inclusion form, introduced in May 2020, has allowed collection of additional clinical information.
Results
Overall, 1902 ATTR-CM patients have been included by 189 physicians from 107 centers. Nine centers included each at least 50 patients, accounting for 1092, or 57.4% of all patients. The median age of the patients was 82 years (IQR=9 years), 82% were male, and, 12.4%, 58.8% and 28.7% of patients had a NYHA class of I, II and III, respectively. For almost all patients, the diagnosis of restrictive/infiltrative heart failure was based on heart MRI and/or echocardiography (98.5%; among the 601 patients included from May 2020 28.8% had both exams, 69.7% echo only and 1.6% MRI only), the infiltrative nature of the cardiomyopathy had been confirmed by bone scintigraphy (99.3%), and the absence of light chains had been confirmed by protein electrophoresis or Bence Jones proteinuria (96.6%). Genetic test was performed in 1205 patients (69.4%). Out of the 884 patients who had a genetic test result available at the time of initial prescription, 762 (86.2%) were affected with the wild-type form and 122 (13.8%) with the hereditary form. Among the 601 patients included from May 2020, a hospitalization for cardiovascular condition within the 6 months preceding tafamidis initiation was reported for 22.3% of them, and tafamidis was initiated within 12 months after diagnosis for 92% of them (only 8% initiated the treatment beyond that period).
Conclusion
The RTU program has provided 1902 ATTR-CM patients with early access to tafamidis over 24 months, in France. Overall, as compared to patients included in ATTR-ACT, the pivotal trial, RTU patients were older, the proportion of wild-type was slightly higher, and NYHA distributions were similar.

Abstract
AIMS The most common autosomal recessive limb girdle muscular dystrophy is associated with the CAPN3 gene. The exclusively recessive inheritance of this disorder has been recently challenged by the description of the recurrent variants, c.643_663del21 [p.(Ser215_Gly221del)] and c.598_612del15 [p.(Phe200_Leu204del)], associated with autosomal dominant inheritance. Our objective was to confirm the existence of autosomal dominant calpainopathies. METHODS Through our activity as one of the reference centres for genetic diagnosis of calpainopathies in France and the resulting collaborations through the French National Network for Rare Neuromuscular Diseases (FILNEMUS), we identified four families harbouring the same CAPN3 heterozygous variant with supposedly autosomal dominant inheritance. RESULTS We identified a novel dominantly inherited CAPN3 variant, c.1333G>A [p.(Gly445Arg)] in 14 affected patients from four unrelated families. The complementary phenotypic, functional and genetic findings correlate with an autosomal dominant inheritance in these families, emphasizing the existence of this novel transmission mode for calpainopathies. The mild phenotype associated with these autosomal dominant cases widens the phenotypic spectrum of calpainopathies and should therefore be considered in clinical practice. CONCLUSIONS We confirm the existence of autosomal dominant calpainopathies as an entity beyond the cases related to the in-frame deletions c.643_663del21 and c.598_612del15, with the identification of a novel dominantly inherited and well-documented CAPN3 missense variant, c.1333G>A [p.(Gly445Arg)]. In addition to the consequences for genetic counselling, the confirmation of an autosomal dominant transmission mode for calpainopathies underlines the importance of re-assessing other myopathies for which the inheritance is considered as strictly autosomal recessive.

Abstract
PURPOSE This study aims to clinically evaluate, at mid-term follow-up, a group of patients treated by the senior author in the last 6 years with our anatomical double-bundle reconstruction surgical technique for the medial ulnar collateral ligament (M-UCL) insufficiency. METHODS In this study, we included only patients affected by chronic valgus elbow instability, diagnosed with an accurate clinical evaluation combined with an MRI, without associated fractures that had been surgically treated in the past and without additional instability detected during the first checkup and in the preoperative evaluation under anesthesia. The nine patients enrolled were operated by the senior author between 2011 and 2014 (from 16 to 49 years old at surgery, all amateur sportsmen). The average follow-up is 4 years (47.6 months). The values of the range of movement were recorded and compared. Pain assessment was performed using the VAS scoring system. The recovery of daily activities was evaluated through the validated MEPS and Quick-DASH score scales. All patients underwent an X-ray in two standard projections and a preoperative and follow-up MRI. RESULTS The recovery of the range of motion was complete in six cases. The remaining three patients had minor loss of extension. None of the patients reported flexion deficits nor pronation-supination at follow-up. All patients achieved subjectively perceived stability and clinically objectified stability at follow-up. Five patients referred a total lack of pain at follow-up. Seven patients achieved full marks in the Mayo Elbow Performance Score and an excellent improvement in the Quick-DASH score. CONCLUSIONS Excellent functional results indicate that M-UCL isolated reconstruction with autologous hamstrings described in this study is a reliable and replicable technique with a reduced incidence of complications. Resuming sports is consistently successful in our patients.

Abstract
Purpose
The aim of this prospective study was to compare and correlate clinical, MRI, and arthroscopic findings in cases of suspected meniscal tears. Using arthroscopic findings as the gold standard, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of clinical investigation and MRI were evaluated to determine if is possible, after a careful examination, to bypass MRI and perform directly arthroscopy in suspected cases.
Methods
A total of 80 patients with a history of knee trauma, preoperative RX, and MRI underwent arthroscopy over an 8-month period at our department. All patients had a clinical examination performed by an experienced knee surgeon. These examiners evaluated and recorded the results of three tests: medial and lateral joint line tenderness test, McMurray's test, and Apley's test. The injury was classified as a meniscal tear if there were at least two positive tests. Finally, using the arthroscopic findings as the gold standard, sensibility, specificity, accuracy, positive and negative predictive values of clinical examination, and MRI were evaluated and compared.
Results
Clinical examination performed by an experienced knee surgeon reported better sensitivity (91 vs. 85%), specificity (87 vs. 75%), accuracy (90 vs. 82%), positive predictive value (94 vs. 88%), and negative predictive value (81 vs. 71%) than MRI for medial meniscal tears. These parameters showed minimal differences for lateral meniscal tears.
Conclusion
Clinical examination performed by an experienced knee surgeon provided equal or better results to diagnose meniscal injuries in comparison to MRI. MRI is not necessary to confirm these lesions and should not be used as the primary diagnostic tool.
Level of Evidence
Level II, prospective study.

Abstract
OBJECTIVE The present research wants to take a picture of the current epidemiological scenario regarding HCV infection in Italy. Studies used to estimate HCV burden of illness in Italy were so far local and performed a number of years ago, not mirroring the state of the art. EpaC wanted to provide a real number of diagnosed patients, eligible to new anti-HCV therapies. PATIENTS AND METHODS EpaC is the most important Italian NGO for hepatopathic patients. A number of sources were cross-checked. Starting from all regional data regarding HCV-related exemptions, a correction/integration was performed with online questionnaire to associated patients (from which we derived patients cured and also other/no exemptions); survey to all prescribing centers in Italy (from which we derived the percentage of ineligible patients); prevalence of particular subpopulations was also collected (prisoners and HIV/HCV coinfected); calculations of new diagnosed, dead and cured patients in 2015. Excluded patients were illegal immigrants and active drug addicts (subpopulations currently rarely cured). RESULTS A total of 221,549 patients were derived from regional exemptions databases and the mean national prevalence was 0.364%. Adding patients without exemptions/other exemptions, total was 308,624. We deducted the yearly deaths, cured and not eligible patients and, last, integrated with coinfected and prisoner special groups. Prevalence was also estimated at regional level, highlighting a reduction of the typical North-to-South prevalence gradient. Applying the above-mentioned corrections/integrations, total diagnosed and eligible HCV patients in Italy who can be immediately cured are supposed to range 163,148-187,756. CONCLUSIONS This is a research aimed at filling an informative gap able to provide useful actual information in terms of HCV patients real-life management and future resource allocation. These data may be considered the basis for policy- and decision-makers to plan and manage patients ready to be cured. The research does not provide information on patients not yet diagnosed.

Abstract
Our objective was to investigate the pattern of damage accumulation in patients with juvenile-onset systemic lupus erythematosus (JSLE) and the relationship between damage accrual, disease flares and cumulative drug therapies. All patients with SLE followed prospectively in three tertiary care centres were identified. Only patients who presented within 12 months of diagnosis and were followed for at least three years were included. Damage was measures based on chart review using the SLICC/ACR damage index (SDI), which was modified (M-SDI) by adding the item growth failure. Mild-moderate and severe disease flares were defined by the increase in SLEDAI-2K. The cumulative duration of drug therapies was calculated in each patient. Fifty-seven patients were included. The mean M-SDI score for the whole patient group increased over time, from 0.1 at one year to 0.8 at three years to 1.5 at five years. Ocular and renal damage and growth failure were observed most frequently. Compared to patients with stable damage, patients who accrued new damage had a significantly greater frequency of severe disease flare in the first three years of follow-up. No significant difference was observed in any cumulative drug therapy between patients who accrued damage and those who did not. Damage accrual was associated with severe disease flares, suggesting that judicious use of immunosuppressive agents to achieve prompt control of severe exacerbation of disease activity is important in minimizing damage in patients with JSLE.

Abstract
Massively parallel sequencing, otherwise known as high-throughput or next-generation sequencing, is rapidly gaining wide use in clinical practice due to possibility of simultaneous exploration of multiple genomic regions. More than 300 genes have been implicated in neuromuscular disorders, meaning that many genes need to be considered in a differential diagnosis for a patient affected with myopathy. By providing sequencing information for numerous genes at the same time, massively parallel sequencing greatly accelerates the diagnostic processes of myopathies compared to the classical "gene-after-gene" approach by Sanger sequencing. In this review, we describe multiple advantages of this powerful sequencing method for applications in myopathy diagnosis. We also outline recent studies that used this approach to discover new myopathy-causing genes and to diagnose cohorts of patients with muscular disorders. Finally, we highlight the key aspects and limitations of massively parallel sequencing that a neurologist considering this test needs to know in order to interpret the results of the test and to deal with other issues concerning the test.

Abstract
This study aims at evaluating sources and processes affecting NO₃(-) concentrations in the Oglio River. Five sampling campaigns considered the main watercourse, tributaries, point pollution sources, springs, and groundwater. Physico-chemical parameters, N forms, B, Sr(2+), stable isotopes (δ(2)HH₂O, δ(18)OH₂O, δ(15)NNO₃, δ(18)ONO₃, δ(11)B) and discharge were measured. Hydrological modelling was performed using mass balance and End Member Mixing Analysis equations. During the irrigation period, in the upstream reach, up to 90% of the natural river flow is diverted for irrigation and industrial purposes; excess water drained from agricultural fields is returned to river in the downstream reach. Results evidenced, in the middle reach, a large input of NO₃(-)-rich groundwater which could be quantified using hydrological modelling. Groundwater inputs are responsible for the sharp, tenfold increase in NO₃(-) in the river water, from 2.2-4.4 up to 33.5 mgL(-1), and are more evident in summer, when discharge is lower. Nevertheless, river water preserves its natural B isotopic composition, indicating that the two tracers do not have a common origin and are not co-migrant. In the lower plain, surface-groundwater interconnections and human disturbances in the water cycle favour the recycling of the compounds in the environment, and lead to a similarity in composition of the different water bodies (Oglio River, tributaries and groundwater). The long lasting agronomical practices have profoundly modified the surface-groundwater equilibrium and chemical characteristics, resulting in a highly buffered system. Infiltrating irrigation water leaches down NO₃(-) which is subsequently denitrified; when returned to the Oglio River, groundwater modifies the river water composition by dilution, in the case of NO₃(-), or by addition, for other constituents (e.g. Cl(-), B). The results of this study indicate that, in order to reduce the NO3(-) transport towards the Adriatic Sea, groundwater contamination should be addressed first, with expected long recovery times.

Abstract
Dysferlinopathies are autosomal recessive muscular dystrophies caused by DYSF mutations, which lead to a reduced amount or a complete lack of dysferlin. One step in dysferlinopathies diagnosis consists in Western blot analysis of proteins extracted from muscle biopsy, or blood monocytes. We have taken advantage of dysferlin expression in monocytes to develop a whole blood flow cytometry (WBFC), using antibodies directed against dysferlin. Six patients were submitted to WBFC analysis and immunofluorescence analysis on monocytes. Results obtained are correlated to Western blot from monocytes and muscle biopsies. The possible usefulness of this flow cytometry analysis in routine diagnosis is presented.

Abstract
BACKGROUND The haemodynamic effects of revascularisation with combined bypass and free-muscle flap remain controversial. In a porcine experimental model, we investigated the transplantation-induced changes in the haemodynamics of a Y-shaped combined arterial autograft bypass-muscle flap (AABF). METHODS Anatomy of AABF was identified in eight dissections in four porcine cadavers. In five animals, AABF served as a superficial femoral artery (SFA) defect replacement. Modelled, triggered pulsatile pressure (P) and flow (Q) waves delivered mean haemodynamics and PQ hysteresis loops before and after transplantation at days 0 and 10. RESULTS Anatomically, AABF combined subscapular and circumflex-scapular arteries, and thoracodorsal artery as latissimus dorsi flap pedicle. Surgical feasibility and AABF patency were confirmed in each case. At day 0, the proximal flow was increased in the grafted Y-shaped AABF, which also adopted the specific SFA pulsatile haemodynamics. Regulatory mechanisms of AABF vasomotricity were preserved and AABF-flow-dependence amplified the flow in the distal segment, which otherwise preserved its own flow dependence. At 10 days, the AABF flow was unchanged in the distal segment, and remained elevated in the proximal and pedicle segments. CONCLUSIONS Combined AABF, as a single one-piece arterial autograft, was shown highly adaptive to the receiving arteries. The transplantation-induced changes in AABF pulsatile flow profile and vascular reactivity improve the overall graft flow, and strongly advocate for beneficial effects on the blood propelling capacity of the grafted circulation.

Abstract
Collectively, angiogenic ocular conditions represent the leading cause of irreversible vision loss in developed countries. In the US, for example, retinopathy of prematurity, diabetic retinopathy and age-related macular degeneration are the principal causes of blindness in the infant, working age and elderly populations, respectively. Evidence suggests that vascular endothelial growth factor (VEGF), a 40kDa dimeric glycoprotein, promotes angiogenesis in each of these conditions, making it a highly significant therapeutic target. However, VEGF is pleiotropic, affecting a broad spectrum of endothelial, neuronal and glial behaviors, and confounding the validity of anti-VEGF strategies, particularly under chronic disease conditions. In fact, among other functions VEGF can influence cell proliferation, cell migration, proteolysis, cell survival and vessel permeability in a wide variety of biological contexts. This article will describe the roles played by VEGF in the pathogenesis of retinopathy of prematurity, diabetic retinopathy and age-related macular degeneration. The potential disadvantages of inhibiting VEGF will be discussed, as will the rationales for targeting other VEGF-related modulators of angiogenesis.

Abstract
OBJECTIVE To investigate the relationship between the magnitude of clinical response in the first 6 months of methotrexate (MTX) therapy and long-term outcome in children with juvenile idiopathic arthritis (JIA). METHODS The clinical charts of 125 JIA patients who were started with MTX and then followed for at least 5 years were reviewed. Based on the level of American College of Rheumatology (ACR) Pediatric response at 6 months, patients were divided in four mutually exclusive groups: (1) non-responders, (2) responders at 30%, (3) responders at 50%, and (4) responders at 70%. The long-term outcome in each response group was evaluated by calculating the percentage change in active and restricted joint counts from baseline to 1, 2 and 5 years and the frequency of inactive disease at 5 years. RESULTS At 6 months, 42 patients were classified as non-responders, 24 as 30% responders, 26 as 50% responders, and 33 as 70% responders. Patients who had achieved a 70% response showed a significantly greater percentage improvement in active joint count between baseline to 5 years compared with non-responders and 30% responders, and a significantly greater percentage improvement in restricted joint count between baseline to 5 years compared with 30% responders. The 70% responders also had a greater frequency of inactive disease at 5 years compared with 30% responders, CONCLUSIONS Our results show that the achievement of an ACR Pediatric 70 response at 6 months after start of MTX therapy predicts a more favorable long-term outcome of patients with JIA.
