Abstract
Wastewater-based epidemiology is experiencing exponential development. Despite undeniable advantages compared to patient-centered approaches (cost, anonymity, survey of large populations without bias, detection of asymptomatic infected peoples…), major technical limitations persist. Among them is the low sensitivity of the current methods used for quantifying and sequencing viral genomes from wastewater. In situations of low viral circulation, during initial stages of viral emergences, or in areas experiencing heavy rains, the extremely low concentrations of viruses in wastewater may fall below the limit of detection of the current methods. The availability during crisis and the cost of the commercial kits, as well as the requirement of expensive materials such as high-speed centrifuge, can also present major blocks to the development of wastewater-based epidemiological survey, specifically in low-income countries. Thereby, highly sensitive, low cost and standardized methods are still needed, to increase the predictability of the viral emergences, to survey low-circulating viruses and to make the results from different labs comparable. Here, we outline and characterize new protocols for concentrating and quantifying SARS-CoV-2 from large volumes (500 mL-1 L) of untreated wastewater. In addition, we report that the methods are applicable for monitoring and sequencing. Our nucleic acid extraction technique (the routine C: 5 mL method) does not require sophisticated equipment such as automatons and is not reliant on commercial kits, making it readily available to a broader range of laboratories for routine epidemiological survey. Furthermore, we demonstrate the efficiency, the repeatability, and the high sensitivity of a new membrane-based concentration method (MBC: 500 mL method) for enveloped (SARS-CoV-2) and non-enveloped (F-specific RNA phages of genogroup II / FRNAPH GGII) viruses. We show that the MBC method allows the quantification and the monitoring of viruses in wastewater with a significantly improved sensitivity compared to the routine C method. In contexts of low viral circulation, we report quantifications of SARS-CoV-2 in wastewater at concentrations as low as 40 genome copies per liter. In highly diluted samples collected in wastewater treatment plants of French Guiana, we confirmed the accuracy of the MBC method compared to the estimations done with the routine C method. Finally, we demonstrate that both the routine C method processing 5 mL and the MBC method processing 500 mL of untreated wastewater are both compatible with SARS-CoV-2 sequencing. We show that the quality of the sequence is correlated with the concentration of the extracted viral genome. Of note, the quality of the sequences obtained with some MBC processed wastewater was improved by dilutions or enzyme substitutions suggesting the presence of specific enzyme inhibitors in some wastewater. To the best of our knowledge, our MBC method is one of the first efficient, sensitive, and repeatable method characterized for SARS-CoV-2 quantification and sequencing from large volumes of wastewater.

Abstract
The French Armed Forces Biomedical Research Institute (IRBA) deeply involved in research on SARS-COV-2, participated in the creation of the Obépine sentinel network in charge of detecting, qualifying and quantifying the virus genome in wastewater in France. During this pandemic, wastewater-based epidemiology has proven to be a first class public health tool for assessing viral dynamics in populations and environment. Obépine has also conducted research demonstrating the low infectivity of faeces and wastewater and allowed for early detection of epidemic waves linked to new variants. The IRBA has adapted this powerful tool to the monitoring of viral infections on board the aircraft carrier Charles-de-Gaulle in order to get an operational system for anticipation after the first local outbreak in 2020. The presence of this surveillance and anticipation tool has allowed a better management of SARS-CoV-2 contingent introductions on board during stopovers or crewmembers entries. The combination of a mandatory vaccination protocol and the surveillance of viral circulation in black waters has made it possible to identify and locate cases, and thus to continue the operational mission in the COVID-19 environment while limiting the spread and preserving the health of the crew. This innovative tool can easily be redirected to the search for any other pathogens in blackwater or even, in the long term, to ensure health surveillance of any military establishment, at sea or on land, in France or on overseas bases.

Abstract
Background Systemic pentavalent antimonials, mainly meglumine antimoniate, continue to be the first-choice drugs for treatment of cutaneous leishmaniasis (CL) despite their toxicity, difficulty of administration and high cost. In the search for therapeutic alternatives, combining two treatment interventions has emerged as a potential alternative to either reduce the use of antimonials with the associated toxicities, or to increase efficacy. Here, we report the results of a recently completed trial assessing the efficacy and safety of a combination of thermotherapy (TT) plus a short course of miltefosine (MLT) for the treatment of uncomplicated CL in Colombia and Peru. Methods A multicenter, randomized, evaluator-blinded, phase II, controled clinical trial was conducted. Adult volunteers with a parasitologically confirmed diagnosis of uncomplicated CL were randomly allocated to receive either a single session of TT or a combination of TT plus a short course of MLT (3 weeks). Therapeutic response outcomes and safety were assessed. Results 130 subjects were included in the study, of whom 64 were randomly assigned to the TT arm and 66 to the TT + MLT arm. Cure at 3 months’ follow-up was achieved in 57.8% (n = 37) and 80.3% (n = 53) in the TT and TT + MLT groups, respectively, in the intention to treat analysis. The TT + MLT regimen was better that TT alone (p = 0.0055). The presence of vesicles at the site of heat application was the most common adverse event reported associated with the use of TT; while vomiting (31.8%) and elevation of liver enzymes (28.8%) were the most frequent adverse events reported associated with the use of MLT. Conclusion The combination of TT plus a short course of MLT was shown to be significantly better than TT alone for the treatment of uncomplicated CL in the New World. Trial registration Registered in clinicaltrials.gov NCT02687971. Cutaneous leishmaniasis is a disease caused by Leishmania parasites transmitted by sandflies. It is a complex and neglected disease. Generally, it manifests as ulcers, nodules, or other lesions, mainly on the face and extremities. An estimated 0.7–1 million new cases occur annually in around 88 countries in South and Central America, Africa, Europe, the Middle East, and Asia, with the appearance of new outbreaks in different regions of the world. For more than 70 years, pentavalent antimonials have been the first line treatment, despite their toxicity, varying efficacy and need of administration of painful injections for 20 days or more. There is limited availability of effective and safe treatment alternatives and the strength of scientific evidence on the efficacy and safety of the different schemes is variable, limiting the control of the disease from a therapeutic approach. Hence the need for effective, safe, low-cost treatment alternatives with non-invasive routes of administration. This article reports the results of a clinical trial aiming to evaluate a combined therapy with two therapeutic alternatives (miltefosine and thermotherapy) approved for the treatment of cutaneous leishmaniasis, comparing it with thermotherapy alone. In this study, the combined therapy was significantly better than the monotherapy in managing cutaneous leishmaniasis.

Abstract
SARS-CoV-2 is a coronavirus causing a globalized outbreak called COVID-19. SARS-CoV-2 transmission is associated with inhalation of contaminated respiratory droplets and could causes severe complications. Until today several "waves" of infections have been observed despite implementation of strict health policies. Decisions for such sanitary measures are based on population health monitoring. Unfortunately, for COVID-19, a significant proportion of individuals are asymptomatic but play a role in the virus transmission. To overcome these limitations, several strategies were developed including genome quantification in wastewater that could allow monitoring of the health status of population, since shedding of SARS-CoV-2 in patient stool is frequent. Wastewater-based epidemiology (WBE) was established and several countries implemented this approach to allow COVID-19 outbreak monitoring. In France, the OBEPINE project performed a quantitative analysis of SARS-CoV-2 in raw wastewater samples collected from major wastewater treatment plants (WWTP) since March 2020. In the greater Paris area 1101 samples (507 for five WWTP and 594 for sewer) were collected. This 16 months monitoring allows us to observe the outbreak dynamics. Comparison of WBE indicators with health data lead to several important observation; the good level of correlation with incidence rates, the average 3 days lead time, and the sensitivity (WBE change when incidence is > to 7/100000 inhabitants). We also compared the local monitoring (city level) with the regional monitoring, to help cluster identification. Moreover, variants of concern (VOC) emerged due to the selection pressure. We developed a specific RT-qPCR method targeting the deletion H69-V70 in the spike protein, using this deletion as a proxy of the B.1.1.7 presence in the wastewater. With this data we demonstrate the predominant role played by this strain in the third wave. All these results allow a better description and understanding of the pandemic and highlight the role of such WBE indicators.

Abstract
The ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a public health emergency of international concern. Although SARS-CoV-2 is considered to be mainly transmitted by inhalation of contaminated droplets and aerosols, SARS-CoV-2 is also detected in human feces and to a less extent in urine, and in raw wastewaters (to date viral RNA only) suggesting that other routes of infection may exist. Monitoring SARS-CoV-2 genomes in wastewaters has been proposed as a complementary approach for tracing the dynamics of virus transmission within human population connected to wastewater network. The understanding on SARS-CoV-2 transmission through wastewater surveillance, the development of epidemic modeling and the evaluation of SARS-CoV-2 transmission from contaminated wastewater are largely limited by our knowledge on viral RNA genome persistence and virus infectivity preservation in such an environment. Using an integrity based RT-qPCR assay this study led to the discovery that SARS-CoV-2 RNA can persist under several forms in wastewaters, which provides important information on the presence of SARS-CoV-2 in raw wastewaters and associated risk assessment.

Abstract
We generated human induced pluripotent stem cells (hiPSCs) from dermal fibroblasts of a 40 years old female patient homozygous for the mutation c.535 G > A p.G179S on the KCNQ1 gene, causing a severe form of autosomal recessive Long QT Syndrome type 1 (AR-LQT1). The hiPSCs, generated using classical approach of the four retroviruses enconding the reprogramming factors OCT4, SOX2, cMYC and KLF4, display pluripotent stem cell characteristics, and differentiate into cell lineages of all three germ layers: endoderm, mesoderm and ectoderm.

Abstract
We generated PSMi001-A and PSMi008-A hiPSC lines from two individuals belonging to a South African (SA) founder population in which the malignant KCNQ1-A341V mutation cosegregates with the Long QT Syndrome (LQTS) phenotype. PSMi001-A was derived from an asymptomatic KCNQ1-A341V mutation carrier, whereas PSMi008-A was derived from a healthy non-mutation carrier, heterozygous for the minor variant rs16847548 on the NOS1AP gene, associated with QT prolongation in the general population, and with a greater risk for cardiac arrest in the affected members of the SA founder population. The hiPSCs, generated using the Yamanaka's retroviruses, display pluripotent stem cell features and trilineage differentiation potential.

Abstract
BACKGROUND & AIMS Gender-related differences represent an emerging investigation field to better understand obesity heterogeneity and paradoxically associated cardiovascular (CV) risk. Here, we investigated if high-sensitivity C-reactive protein (hs-CRP) might differently affect adiposity and predict the clinical response to bariatric surgery in obese males and females. METHODS AND RESULTS In 110 morbidly obese patients undergoing laparoscopic sleeve gastrectomy, hs-CRP as well as anthropometric assessment of adiposity, completed by electric bioimpedance and ultrasonography quantification of visceral fat area (VFA), were measured before and one year after surgery. As compared to males, obese female showed less severe overweight and prevalent subcutaneous fat deposition, but higher circulating hs-CRP. In obese females, hs-CRP was associated with VFA at baseline, independently of body mass index (BMI) and visceral adiposity index (OR 1.022 [95% CI 1.001-1.044]; p = 0.039). Based on decreases and increases in hs-CRP levels after surgery, two distinct subgroups of females were identified. Post-surgery decreases in hs-CRP was predominantly observed in patients with higher baseline levels of hs-CRP and associated with greater reduction of weight, BMI, fat and lean mass, VFA and visceral to subcutaneous fat ratio. Finally, we observed that high baseline values of hs-CRP were able to predict VFA reduction one-year after surgery, independently of BMI and visceral adiposity index (VAI) loss (OR 1.031 [95% CI 1.009-1.053]; p = 0.005). CONCLUSION In obese females, hs-CRP levels might be a promising biomarker of visceral fat amount and dysfunction, in addition to predict the effectiveness of bariatric surgery in terms of loss of VFA one-year after surgery.

Abstract
Splenic hematopoiesis is a major feature in the course of myelofibrosis (MF). In fact, the spleen of patients with MF contains malignant hematopoietic stem cells retaining a complete differentiation program, suggesting both a pivotal role of the spleen in maintaining the disease and a tight regulation of hematopoiesis by the splenic microenvironment, in particular by mesenchymal stromal cells (MSCs). Little is known about splenic MSCs (Sp-MSCs), both in normal and in pathological context. In this work, we have in vitro expanded and characterized Sp-MSCs from 25 patients with MF and 13 healthy subjects (HS). They shared similar phenotype, growth kinetics, and differentiation capacity. However, MF Sp-MSCs expressed significant lower levels of nestin, and favored megakaryocyte (Mk) differentiation in vitro at a larger extent than their normal counterpart. Moreover, they showed a significant upregulation of matrix metalloprotease 2 (MMP2) and fibronectin 1 (FN1) genes both at mRNA expression and at protein level, and, finally, developed genetic abnormalities which were never detected in HS-derived Sp-MSCs. Our data point toward the existence of a defective splenic niche in patients with MF that could be responsible of some pathological features of the disease, including the increased trafficking of CD34+ cells and the expansion of the megakaryocytic lineage.

Abstract
We report the generation of human induced pluripotent stem cells (hiPSCs) from dermal fibroblasts of a female patient carrier of the two compound heterozygous mutations c.568 C>T p.R190W (maternal allele), and c.1781 G>A p.R594Q (paternal allele) on the KCNQ1 gene, causing Jervell and Lange-Nielsen Syndrome (JLNS). To obtain hiPSCs, we used the classical approach of the four retroviruses each encoding for a reprogramming factor OCT4, SOX2, KLF4, cMYC. The obtained hiPSC clones display pluripotent stem cell characteristics, and differentiate into spontaneously beating cardiomyocytes (hiPSC-CMs).

Abstract
Introduction Progress with the treatment of cutaneous leishmaniasis (CL) has been hampered by inconsistent methodologies used to assess treatment effects. A sizable number of trials conducted over the years has generated only weak evidence backing current treatment recommendations, as shown by systematic reviews on old-world and new-world CL (OWCL and NWCL). Materials and methods Using a previously published guidance paper on CL treatment trial methodology as the reference, consensus was sought on key parameters including core eligibility and outcome measures, among OWCL (7 countries, 10 trial sites) and NWCL (7 countries, 11 trial sites) during two separate meetings. Results Findings and level of consensus within and between OWCL and NWCL sites are presented and discussed. In addition, CL trial site characteristics and capacities are summarized. Conclusions The consensus reached allows standardization of future clinical research across OWCL and NWCL sites. We encourage CL researchers to adopt and adapt as required the proposed parameters and outcomes in their future trials and provide feedback on their experience. The expertise afforded between the two sets of clinical sites provides the basis for a powerful consortium with potential for extensive, standardized assessment of interventions for CL and faster approval of candidate treatments. The term ‘cutaneous leishmaniasis’ (CL) includes a range of manifestations affecting the skin caused by Leishmania parasites across several continents. While not life-threatening, CL can be invalidating and disfiguring, or become complicated. Today, there is no satisfactory treatment for CL that is effective and safe. Faced with no investments into developing drugs for CL, clinical researchers have tried many treatments over the years, but little progress has been made. One of the reasons is the lack of standardized methodologies in conducting these trials which makes it difficult to collate and compare results. Clinical researchers now realize that their efforts can be brought to fruition if common methodologies are available and applied. This paper summarizes the principles and parameters agreed upon by researchers of how to identify patients and how to measure treatment effects in a way that will make it possible to gather convincing evidence of whether a treatment works or not. Adhering to these principles will allow faster progress towards offering better care to patients with this neglected disease.

Abstract
In January 2016, a large-scale outbreak of acute gastroenteritis was reported among French armed forces deployed in the Central African Republic. Challenging investigations, conducted from France, made it possible to identify a norovirus genogroup II in both stool and food samples, confirming a norovirus foodborne disease outbreak. Infected food handler management is discussed.

Abstract
INTRODUCTION The association between congenital pulmonary airway malformations (CPAM) and malignancy is reported in the literature. Interactions between the tumor, immune, and mesenchymal stromal/stem cells (MSCs) have been recognized as crucial for understanding tumorigenesis. We characterized MSCs isolated from CPAM lesions in order to define potential malignancy risks. METHODS CPAM II pulmonary tissue was used for MSC expansion; a "healthy" lung section from the same child was used as a comparator. Morphology, immunophenotype, differentiation and immunological capacity, proliferative growth, gene signature telomerase activity, and in vivo tumorigenicity in nude mice were evaluated. RESULTS MSCs were successfully isolated and propagated from CPAM tissue. CPAM-MSCs presented the typical MSC morphology and phenotype, while exhibiting high proliferative capacity, reaching confluence at a median time of 5 days as well as differentiation capabilities. CPAM-MSCs at early passages were not neoplastic and chromosomally normal, even though unbalanced chromosomal rearrangements were noted by molecular karyotype. CONCLUSIONS CPAM-MSCs exhibited specific features similar to tumor derived MSCs. Whilst there was no evidence of malignant transformation in the cystic tissue, our results provide evidence that this abnormal tissue has malignant potential. MSCs are considered important players in the tumor microenvironment and they have been closely linked to regulation of tumor survival, growth, and progression. Thus, early lesion resection also in asymptomatic patients might be indicated to exclude that the microenvironment may be potentially permissive to cancer development.

Abstract
hTERT component is the key regulator of telomerase. Alternatively spliced variants of hTERT generate different telomerase activity. The goal of the study was to determine the role of different hTERT isoforms in the regulation of telomerase expression in AML patients. Among the 97 studied patients, 45 had a complex karyotype and 52 a normal karyotype. hTERT isoforms expression was determined in bone marrow samples by q-RT-PCR, using SYBR Green I. hTERT expression was lower in AML patients than controls (median 2.5 vs. 10.1, p = .003), though no difference was observed between the complex and normal karyotype (median 3.2 vs. 2.3, p = .37). High trans-dominant negative isoform expression increased the response rate by two. High expression of inactive product (-α - β) was shown to increase the risk of relapse by about three times. In conclusion, our data suggest an intriguing link between the control of hTERT isoforms expression and AML outcome.

Abstract
In myelodysplatic syndromes and acute myeloid leukemia (MDS/AML) deletion of the 11q14 region is a rare chromosomal defect (incidence: 0.6-1.0%), included within the intermediate risk criteria by the International Prognostic Scoring System. No fluorescence in situ hybridization (FISH) study has yet been performed to identify a common breakpoint region (CBR). In our study through FISH with bacterial artificial chromosomes and commercial probes, we analyzed seven patients with MDS/AML harboring 11q14 deletion on conventional cytogenetic analysis. FISH revealed deletions in five patients and amplifications in two. Three patients with deletion carried a CBR, two had a deletion involving a more centromeric breakpoint. These five patients exhibited multilineage dysplasia, blast cells with large round nuclei, loose chromatin, small and abundant nucleoli, and vacuolated cytoplasm with very thin Auer bodies. In conclusion, the morphological features which occur independently of the extent of the deletion are of multilineage dysplasia in MDS and leukemic blasts strongly reactive to peroxidase in AML; despite the variable size of the deleted area, some patients harbor a CBR.

Abstract
BACKGROUND AND AIMS Each bariatric surgery procedure impacts differently on cholesterol synthesis and absorption. Although a restrictive procedure, sleeve gastrectomy resolves diabetes mellitus and, like mixed-type procedures, induces early changes in gastrointestinal hormones. To our knowledge the present study is the first to assess the effects of sleeve gastrectomy on cholesterol synthesis and absorption. METHODS AND RESULTS 42 consecutive subjects with obesity and sleeve gastrectomy candidates were included in the study together with a control group of 20 subjects without obesity. Before sleeve gastrectomy and 10 months afterwards, all subjects underwent a clinical examination, blood tests, ultrasound visceral fat area estimation and determination of plasma lathosterol, campesterol and sitosterol concentrations. After sleeve gastrectomy, significant decreases were observed in BMI, waist circumference, visceral and subcutaneous fat, blood pressure, triglycerides, insulin and glucose levels, lathosterol and HOMA-IR. HDL-C and apolipoprotein AI levels increased significantly. No significant differences emerged in LDL-C, apolipoprotein B levels or cholesterol absorption markers. Lathosterol levels correlated significantly with BMI, visceral fat area and HOMA-IR. Differences in cholesterol intake after surgery were not significantly associated with differences in lathosterol, campesterol and sitosterol concentrations. CONCLUSIONS Sleeve gastrectomy reduced the markers of cholesterol synthesis but did not modify cholesterol absorption. Changes in cholesterol synthesis and absorption were independent of variations in cholesterol intake, suggesting a specific sleeve gastrectomy-related effect.

Abstract
The aim of the study was to investigate the involvement of the adipokines eotaxin-3, MIP-1β, and MCP-4 in obesity and related comorbidities and the modification of their circulating levels after bariatric surgery. Eighty severely obese subjects and 20 normal-weight controls were included in the study. Circulating levels of MCP-4, MIP-1β, and eotaxin-3, and the main clinical, biochemical, and instrumental parameters for the evaluation of cardiovascular and metabolic profile were determined in controls and in obese subjects at baseline and 10 months after surgery. Within the obese group at baseline, eotaxin-3 levels were higher in males than females and in smokers than non-smokers and showed a positive correlation with LDL-cholesterol, apolipoprotein B, and leptin. MIP-1β showed a positive correlation with age and leptin and a negative correlation with adiponectin and was an independent predictor of increased carotid artery intima-media thickness. MCP-4 levels were higher in obese subjects than controls and showed a positive correlation with body mass index, eotaxin-3, and MIP-1β. Bariatric surgery induced a marked decrease in all the 3 adipokines. MCP-4 is a novel biomarker of severe obesity and could have an indirect role in favoring sub-clinical atherosclerosis in obese patients by influencing the circulating levels of eotaxin-3 and MIP-1β, which are directly related to the main atherosclerosis markers and risk factors. The reduction of circulating levels of MCP-4, eotaxin-3, and MIP-1β could be one of the mechanisms by which bariatric surgery contributes to the reduction of cardiovascular risk in these patients.

Abstract
A tight relationship between the acute myeloid leukemia (AML) population and the bone marrow (BM) microenvironment has been convincingly established. The AML clone contains leukemic stem cells (LSCs) that compete with normal hematopoietic stem cells (HSCs) for niche occupancy and remodel the niche; whereas, the BM microenvironment might promote AML development and progression not only through hypoxia and homing/adhesion molecules, but also through genetic defects. Although it is still unknown whether the niche influences treatment results or contains any potential target for treatment, this dynamic AML-niche interaction might be a promising therapeutic objective to significantly improve the AML cure rate.

Abstract
Fanconi anaemia (FA) is an inherited disorder characterized by pancytopenia, congenital malformations and a predisposition to develop malignancies. Alterations in the haematopoietic microenvironment of FA patients have been reported, but little is known regarding the components of their bone marrow (BM) stroma. We characterized mesenchymal stromal cells (MSCs) isolated from BM of 18 FA patients both before and after allogeneic haematopoietic stem cell transplantation (HSCT). Morphology, fibroblast colony-forming unit (CFU-F) ability, proliferative capacity, immunophenotype, differentiation potential, ability to support long-term haematopoiesis and immunomodulatory properties of FA-MSCs were analysed and compared with those of MSCs expanded from 15 age-matched healthy donors (HD-MSCs). FA-MSCs were genetically characterized through conventional karyotyping, diepoxybutane-test and array-comparative genomic hybridization. FA-MSCs generated before and after HSCT were compared. Morphology, immunophenotype, differentiation potential, ability in vitro to inhibit mitogen-induced T-cell proliferation and to support long-term haematopoiesis did not differ between FA-MSCs and HD-MSCs. CFU-F ability and proliferative capacity of FA-MSCs isolated after HSCT were significantly lower than those of HD-MSCs. FA-MSCs reached senescence significantly earlier than HD-MSCs and showed spontaneous chromosome fragility. Our findings indicate that FA-MSCs are defective in their ability to survive in vitro and display spontaneous chromosome breakages; whether these defects are involved in pathophysiology of BM failure syndromes deserves further investigation.

Abstract
In this paper, laser beam resonant interaction with pendant microdroplets that are seeded with a laser dye (Rhodamine 6G (Rh6G)) water solution or oily Vitamin A emulsion with Rhodamine 6G solution in water is investigated through fluorescence spectra analysis. The excitation is made with the second harmonic generated beam emitted by a pulsed Nd:YAG laser system at 532 nm. The pendant microdroplets containing emulsion exhibit an enhanced fluorescence signal. This effect can be explained as being due to the scattering of light by the sub-micrometric drops of oily Vitamin A in emulsion and by the spherical geometry of the pendant droplet. The droplet acts as an optical resonator amplifying the fluorescence signal with the possibility of producing lasing effect. Here, we also investigate how Rhodamine 6G concentration, pumping laser beam energies and number of pumping laser pulses influence the fluorescence behavior. The results can be useful in optical imaging, since they can lead to the use of smaller quantities of fluorescent dyes to obtain results with the same quality.

Abstract
AIM The use of robotic technology has proved to be safe and effective, arising as a helpful alternative to standard laparoscopy in a variety of surgical procedures. However the role of robotic assistance in laparoscopic rectopexy is still not demonstrated. METHODS A systematic review of the literature was carried out performing an unrestricted search in MEDLINE, EMBASE, the Cochrane Library, and Google Scholar up to 30th June 2014. Reference lists of retrieved articles and review articles were manually searched for other relevant studies. We meta-analyzed the data currently available regarding the incidence of recurrence rate of rectal prolapse, conversion rate, operative time, intra-operative blood loss, post-operative complications, re-operation rate and hospital stay in robot-assisted rectopexy (RC) compared to conventional laparoscopic rectopexy (LR). RESULTS Six studies were included resulting in 340 patients. The meta-analysis showed that the RR does not influence the recurrence rate of rectal prolapse, the conversion rate and the re-operation rate, whereas it decreases the intra-operative blood loss, the post-operative complications and the hospital stay. Yet, the RR resulted to be longer than the LR. Post-operative ano-rectal and the sexual functionality and procedural costs could not meta-analyzed because the data from included studies about these issues were heterogeneous and incomplete. CONCLUSION The meta-analysis showed that the RR may ensure limited improvements in post-operative outcomes if compared to the LR. However, RCTs are needed to compare RR to LR in terms of short-term and long-term outcomes, specially investigating the functional outcomes that may confirm the cost-effectiveness of the robotic assisted rectopexy.

Abstract
Conventional loop ileostomy (CLI) is a suitable procedure for transitory faecal diversion after colocolic or colorectal anastomosis, but it causes relevant morbidities (dehydration, discomfort, peristomal infections) and requires a second operation to be closed. We already described an alternative technique of temporary percutaneous ileostomy (TPI), which can be removed without surgery, as faecal diversion in low colorectal anastomosis. Now we report our experience with the TPI in protecting colocolic and colorectal anastomosis in urgency in elderly. From January 2012 to June 2014, 45 patients underwent urgent surgical procedures for acute abdomen with colonic and/or rectal resections and colocolic or colorectal anastomosis with faecal diversion by TPI. Nineteen out of 45 patients were older than 70. Four low colorectal anastomoses, 10 intra-peritoneal colorectal anastomosis and 4 colocolic anastomosis were performed. Neither intra-operative complications nor post-operative deaths were observed. None of the 19 patients treated had evidence of clinical or radiological leakage of the anastomosis. Post-operative complications occurred in 7 patients and nobody required re-intervention. No intestinal obstruction was reported in the early (30 days) post-operative period. The TPI seems to be a valid alternative to standard ileostomy, ensuring an optimal faecal diversion both in elective surgery and in urgency. The TPI also ensures less patient discomfort and it can be easily removed without surgery, unlike the CLI. The limited duration of the faecal diversion and the uselessness of a second surgical procedure to remove the TPI are the most important advantages of this new technique, especially in elderly.

Abstract
BACKGROUND AND AIM Morbid obesity is often accompanied by insulin resistance and increased ectopic fat surrounding the heart. We evaluated the relation of epicardial and pericardial fat with insulin resistance and left ventricular (LV) structure and function. METHODS AND RESULTS Epicardial and pericardial fat thicknesses were determined at 2-dimensional echocardiography in 80 morbid obese subjects [age 42 ± 12 years, 31% men, body mass index (BMI) 44.4 ± 7 kg/m(2)]. LV hypertrophy (LV mass ≥51 g/m(2.7)), inappropriately high LV mass for a given cardiac workload (observed vs predicted LV mass >128%), and stress-adjusted LV mid-wall fractional shortening were determined. Pericardial and epicardial fat thicknesses had direct associations with BMI (r = 0.40 and 0.45, both p < 0.01) and waist circumference (r = 0.37 and 0.45, both p < 0.01). Pericardial (partial r = 0.35, p < 0.01), but not epicardial fat thickness (partial r = 0.05, p = n.s.), was correlated with homeostasis model assessment-insulin resistance after adjustment for BMI. Pericardial fat also had a strong negative correlation with mid-wall fractional shortening (p = 0.01) and a positive one with inappropriately high LV mass (p < 0.01), while no such relation was found for epicardial fat (both p = n.s.). Independently of age, male sex, BMI, and anti-hypertensive treatment, pericardial fat thickness had an independent positive association with inappropriately high LV mass (β = 0.29, p = 0.02), and a negative one with stress-adjusted mid-wall fractional shortening (β = -0.26, p = 0.04). CONCLUSIONS Pericardial fat thickness is associated with insulin resistance, inappropriately high LV mass, and LV systolic dysfunction in obese individuals. Findings from this study confirm the existence of a connection between insulin resistance, cardiac ectopic fat deposition and cardiac dysfunction in morbid obesity.

Abstract
Transcribed gene fusions are key biomarkers in many hematologic and solid tumors, often representing the primary oncogenic driver mutation. Here, we report an experimental and computational pipeline for detecting fusion transcripts using single-molecule RNA FISH and unbiased correlation analysis (FuseFISH). We constructed a genome-wide database of optimal oligonucleotide sequences, enabling quick design of FuseFISH probes against known and novel fusions. We implemented FuseFISH in cell lines, tissue sections, and purified RNA, reliably detecting one BCR-ABL1 positive in 10,000 negative cells. In 34 hematologic samples, we detected BCR-ABL1 transcripts with high specificity and sensitivity. Finally, we measured BCR-ABL1 expression heterogeneity and dynamics in single CML cells exposed to the kinase inhibitor Nilotinib. Our resource and methods are ideal for streamlined validation of fusions newly identified by next-generation sequencing, and they pave the way to studying the impact of fusion expression variability on clinical outcome.

Abstract
This study evaluated whether the NCCSS truly improves the prognostic stratification of 630 consecutive de novo MDS patients and established which cytogenetic grouping [NCCSS or International Prognostic Scoring System (IPSS)], when combined with the WHO classification, best predicted the clinical outcome of myelodysplastic syndromes (MDS). The frequency of chromosomal defects was 53.8%. Clinical parameters, including number of cytopenias, WHO classification, IPSS cytogenetic categories and scores, NCCSS were all relevant for overall survival (OS) and leukemia-free survival (LFS) and were included in six distinct multivariate models compared by the Akaike Information Criterion (AIC). The most effective model to predict OS included the number of cytopenias, the WHO classification and the NCCSS, whereas the model including the number of cytopenias, blast cell percentage and the NCCSS and the model including the number of cytopenias the WHO classification and the NCCSS were almost equally effective to predict LFS. In conclusion, the NCCS (i) improves the prognostic stratification of the good and poor IPSS cytogenetic categories by introducing the very good and the very poor categories; (ii) is still incomplete in establishing the prognostic relevance of rare/double defects, (ii) applied to patients who receive supportive treatment only identifies five different prognostic subgroups, but applied to patients treated with specific therapies reveals only a trend toward a significantly different OS and LFS when patients of the poor and intermediate cytogenetic categories are compared, (iii) combined with the WHO classification is much more effective than the IPSS in predicting MDS clinical outcome.

Abstract
This study analyzed 140 patients with isolated del13q14 on interphase FISH (I-FISH), to identify subsets with a different progression risk and to assess the acquisition of additional chromosomal abnormalities (clonal evolution) in treatment-naïve del13q14 patients. A monoallelic deletion (del13qx1) was detected in 123 cases (88%), a biallelic deletion (del13qx2) in eight and a mosaic of monoallelic and biallelic deletions (del13qx1/del13qx2) in nine. In 33% of cases, deletion encompassed the Rb1 locus The median percentage of abnormal nuclei was 50% (15%-96%), and it was higher in patients with a biallelic/mosaic pattern in comparison with patients with monoallelic deletion. Sixty two patients (44%) have been treated; 5-year treatment free survival rate was 56% and the median treatment free survival was 65 months. The baseline percentage of deleted nuclei, as a continuous variable, was related to progression (HR: 1.02; p = 0.001). According to deletion burden, three groups were identified: 64 cases (46%) had <50% deleted nuclei, 47 (33%) had 50-69% deleted nuclei, and 29 (21%) had ≥70% deleted nuclei. The 5-year untreated rate was 70.5% , 52.6% and 28.7% (p < 0.0001), respectively. In multivariate analysis using IGHV mutational status, presence of a nullisomic clone, CD38 expression and percentage of deleted nuclei as covariates, only IGHV mutational status and the percentage of deleted nuclei were independent risk factors for treatment. In 103 patients serially monitored by I-FISH before starting any treatment, we observed a significant increase in the proportion of del13q14 cells, and this increase affected the risk of subsequent treatment requirement (HR 2.54, p = 0.001). The appearance of a new clone was detected in 16 patients (15.5%) and chromosome 13 was involved in 14 of them. I-FISH monitoring proves worthwhile for a dynamic risk stratification and for planning clinical surveillance.

Abstract
TET2 haplo-insufficiency occurs through different molecular mechanisms and is promptly revealed by array comparative genomic hybridization, single nucleotide polymorphism (SNP) array, and next-generation sequencing (NGS). Fluorescence in situ hybridization (FISH) can effectively demonstrate TET2 deletions and is often used to validate molecular results. In the present study 41 MDS patients with and without 4q abnormalities were analyzed with a series of bacterial artificial chromosome (BAC) probes spanning the 4q22.3-q25 region. On conventional cytogenetic (CC) studies, a structural defect of the long arm of chromosome 4 (4q) was observed in seven patients. In three, one each with a t(1;4)(p21;q24), an ins(5;4)(q23;q24qter), and a t(4;17)(q31;p13) as the sole chromosomal abnormality, FISH with the RP11-356L5 and RP11-16G16 probes, which cover the TET2 locus, produced one signal only. Unexpectedly, this same result was achieved in 3 of the remaining 34 patients. Thus, a TET2 deletion was observed in a total of six patients (14.6%). TET2 deletion was not correlated with any particular clinical findings or outcome. These findings demonstrate that 1) FISH is an effective and economical method to reveal cryptic abnormalities of band 4q22-q24 resulting in TET2 deletions; 2) in these patients, TET2 deletion is the unifying genetic event; and 3) the different breakpoints within the 4q22-q25 region suggest that deletions are not mediated by repetitive sequences.

Abstract
BACKGROUND Photochemical transformation of certain bioactive compounds for the purpose of obtaining derivatives with increased bioactivity is a prospective area of synthetic chemistry. Ecdysteroids, analogs of the insect molting hormone, which can also exert several beneficial effects in mammals including humans, contain an enone moiety in their B ring, and, as such, are good candidates for photochemical transformations. MATERIALS AND METHODS 20-hydroxyecdysone (20E), the most common ecdysteroid in Nature, and the easily obtained derivative 20-hydroxyecdysone 2,3;20,22-diacetonide (20ED), at different concentrations, were exposed to a 266 nm laser beam at an energy level of 6.5 mJ for different periods of time and evaluated for fluorescence emission during the process of irradiation. The products of irradiation were scanned from 200 to 1500 nm and then subjected to one-dimensional and two-dimensional thin layer chromatography. RESULTS During irradiation, progressive significant changes in the fluorescence emission spectra were noted for both compounds with time that were accompanied by changes in their UV-Vis spectra. Full conversion of both compounds was reached within 14 minutes, and both compounds yielded several major products and several minor ones representing a wide polarity range. CONCLUSION The photo-transformation system described here was proven to be a useful and flexibly adjustable tool for the laser-catalyzed conversion of bioactive compounds. Due to the multi-drug resistance reversal activity of the less polar ecdysteroids, several new products are promising for being tested against various cancer cell lines. Fractionation, isolation and characterization of the irradiated products are currently in process.

Abstract
AIM Loop ileostomy is a suitable procedure for transitory faecal diversion after colorectal or coloanal anastomosis. We describe here an easy alternative technique for ileostomy construction that does not require reintervention for the closure. METHOD In twenty patients undergoing anterior resection of the extraperitoneal rectum with colorectal and/or coloanal anastomosis, loop ileostomy was performed using a modified jejunotomy tube inflated with 10 ml of normal saline. The tube was deflated on the eighth post-operative day and removed on day 11 after a radiological contrast enema of the anastomosis. RESULTS Radiological control carried out on day 11 evidenced a premature dislocation of the jejunostomy tube in 1 patient, thus the tube was correctly removed without any complications. In another patient a delayed closure of the ileo cutaneous fistula was recorded that required simple medication over 15 days in the out patient clinic. No signs of anastomotic leakage, either clinical or radiological were evidenced. CONCLUSION We have described here a safe alternative technique for loop ileostomy with negligible complications related to construction as demonstrated in our results.

Abstract
This study correlated chromosomal defects with French-American-British (FAB)/World Health Organization (WHO) classification subtypes, proposed a revised International Prognostic Scoring System (IPSS) cytogenetic grouping; and established which classification, when used with the IPSS cytogenetic categories, best predicted clinical outcome in the myelodysplastic syndromes (MDS). A higher prevalence of chromosomal defects and distinct defects were observed in patients with multi-lineage dysplasia and a blast cell percentage >10%. Abnormalities of the long arm of chromosome 3, del(7)(q31q35), trisomy 8, del(11)(q14q23), del(12p) and 20q- could be segregated from their respective IPSS cytogenetic categories and used to develop new cytogenetic subgroups. Clinical parameters, FAB/WHO classification, IPSS score and standard or revised cytogenetic categories were statistically relevant for overall survival (OS) and progression-free intervals (PFI) and were included within five distinct multivariate models compared by the Akaike Information Criterion. To predict OS, the best models included age, WHO classification and standard or revised IPSS cytogenetic categories; to predict PFI, the best model included the same variables and revised cytogenetic categories. In conclusion, (i) the WHO classification was associated with a more homogeneous cytogenetic pattern than the FAB classification, (ii) WHO classification and standard/revised IPSS cytogenetic categories were much more effective than IPSS for predicting MDS clinical outcome, (iii) revised cytogenetic subgroups predicted PFI more effectively than standard categories.
