Abstract
BACKGROUND The Pacman flap is a modified V-Y advancement flap that showed to be versatile in repairing surgical and non-surgical wounds. Indeed, this flap has been used in any anatomical localization, except for the scalp, where its use has not been reported. Moreover, the versatility of the Pacman flap can be enhanced by applying simple modifications to its original design. MATERIALS AND METHODS A case-series of 23 patients whose surgical breaches were repaired using standard or modified Pacman flap were included in this retrospective study. RESULTS Most patients were male (65.2%) with a median age of 75.7 years. Squamous cell carcinoma was the tumor most commonly removed (60.9%), while scalp and face were the most frequent localizations (30.4%). Although 18 flaps were sculpted in the traditional Pacman shape, 5 were modified to fit the defect and localization. Complications occurred in 30% of flaps, but all of them were minor except for 1 extended necrosis. CONCLUSIONS The Pacman flap can be used to repair surgical wounds localized in any body area, including the scalp. Three modifications can enhance the versatility of the flap and offer new repair options to dermatologic surgeons.

Abstract
Determining the optimal course of treatment for low grade glioma (LGG) patients is challenging and frequently reliant on subjective judgment and limited scientific evidence. Our objective was to develop a comprehensive deep learning assisted radiomics model for assessing not only overall survival in LGG, but also the likelihood of future malignancy and glioma growth velocity. Thus, we retrospectively included 349 LGG patients to develop a prediction model using clinical, anatomical, and preoperative MRI data. Before performing radiomics analysis, a U2-model for glioma segmentation was utilized to prevent bias, yielding a mean whole tumor Dice score of 0.837. Overall survival and time to malignancy were estimated using Cox proportional hazard models. In a postoperative model, we derived a C-index of 0.82 (CI 0.79-0.86) for the training cohort over 10 years and 0.74 (Cl 0.64-0.84) for the test cohort. Preoperative models showed a C-index of 0.77 (Cl 0.73-0.82) for training and 0.67 (Cl 0.57-0.80) test sets. Our findings suggest that we can reliably predict the survival of a heterogeneous population of glioma patients in both preoperative and postoperative scenarios. Further, we demonstrate the utility of radiomics in predicting biological tumor activity, such as the time to malignancy and the LGG growth rate.

Abstract
Gas chromatography (GC) is a separation technique commonly developed for targeted in situ analyses in planetary space missions. It is coupled with low-resolution mass spectrometry to obtain additional structural information and allow compound identification. However, ground-based analyses of extraterrestrial samples have shown the presence of large molecular diversities. For future targeted in situ analyses, it is therefore essential to develop new technologies. High resolution mass spectrometry (HRMS) is currently being spatialized using FT-orbitrap-MS technology. In this contribution, the coupling of gas chromatography with FT-orbitrap-MS is studied for targeted amino acid analyses. The method for enantioselective separation of amino acids was optimized on a standard mixture comprising 47 amino acid enantiomers. Different ionization modes were optimized, chemical ionization with three different reactive gasses (NH3, CH4 and NH3/CH4) and electron impact ionization at different electron energies. Single ion and full scan monitoring modes were compared, and detection and quantification limits were estimated by internal calibration under the optimized conditions. The GC-FT-orbitrap-MS demonstrated its ability to separate 47 amino acid enantiomers with minimal co-elution. Furthermore, due to the high mass resolution and accuracy of FT-orbitrap-MS, with mass extraction, the S/N is close to zero, allowing average LOD values of 10⁻7 M, orders of magnitude lower than conventional GC-MS techniques. Finally, these conditions were tested for enantioselective analysis of amino acids on an analog of a pre-cometary organic material showing similarities to that of extraterrestrial materials.

Abstract
BACKGROUND AND OBJECTIVES Elevated blood lactate levels are associated with poor outcome in several critical conditions. Patients with SARS-CoV-2 rarely develop hyperlactatemia. The purpose of this study is to evaluate the trend of lactatemia in patients affected by mild/moderate SARS-Co V-2-ARDS and if it affected prognosis. METHODS We analyzed blood lactate levels in thirty-eight patients with severe SARS-CoV-2 infection admitted to COVID Care Unit of Santa Maria delle Grazie Hospital, Pozzuoli. RESULTS Twenty patients survived and were discharged at home and 18 patients died. Despite severe hypoxia that affected all patients enrolled, T0 lactate was within normal values. All survivors showed a significant increase in lactate concentration the day prior to clinical improvement. In not-survivors levels of lactate did not increase significantly. CONCLUSION In our study, patients who survive SARS CoV-2 ARDS have a fleeting increase in lactate, which precedes clinical improvement by one day.

Abstract
Budd-Chiari syndrome (BCS) is a rare disease with a variable clinical presentation and often late diagnosis. Doppler ultrasonography (DUS) permits to determine the site of the obstructed venous tracts, the thrombotic or non-thrombotic nature of the obstruction with its morphologic features and the flow-pattern alterations. Other non-specific findings, which are seen in most of the other liver diseases, include ascites, hepatosplenomegaly and caudate hypertrophy. The aim of this study is to show our experience in BCS reporting retrospectively 15 cases referred to our hepatology center between 2017 and 2021. Four selected cases depict the extreme heterogeneous behaviour of BCS and highlight the importance of DUS as a diagnostic tool when there is a clinical suspicion. In patients, mainly young, who present with ascites and abdominal pain, BCS has to be considered and DUS is the first imaging technique to be performed to rule it out.

Abstract
Abstract
Introduction
This study aims to explore perceptions, fears and worries regarding SARS-CoV-2 risk of infection and transmission to relatives and/or co-workers and non-pharmacological preventive interventions among hospital workers.
Materials and Methods
The research used an explorative qualitative approach. Six focus groups and ten individual interviews across multidisciplinary workers (physicians, nurses, aides, cleaners, maintenance, and security staff) were conducted online and audio-recorded, transcribed verbatim and analysed using thematic analysis and mixed coding.
Results
Forty professionals participated in the study. Four common themes emerged in all groups: challenges related to the lack of pandemic preparedness, concerns about personal protective equipment, unclear guidelines for case and contact tracing, and communication-related difficulties.
Conclusions
This study emphasizes the key recommendations to improve non-pharmacological preventive interventions to reduce workers’ fears and worries about the risk of infection and spreading the infection to others, including families. Above all, these should include ensuring the availability, and correct use of adequate personal protective equipment, improve guidelines on case and contact tracing, and setting effective communication channels for all workers of the organization. These recommendations must be reinforced in maintenance and security personnel, as well as night shift nurses and aides, in order to reduce also health inequalities.
Key messages
• Lack of pandemic preparedness increased HCW’ fear of infection, which could be reduced by ensuring the availability and good use of proper PPE, and by clear guidelines on case/contact detection.
• The improvement on non-pharmacological preventive interventions must be underpinned by effective communication channels and/or communication staff, and should reach all workers in the institution.

Abstract
Abstract
Background
Medullary sponge kidney is generally considered a benign condition, gold standard for the diagnosis is urography but it has almost been replaced by UroCT that did not present the same sensibility. Although it is really rare, our sonography’s findings were consistent with medullary sponge kidney in the transplanted kidneys.
Case presentation
A 45-year-old woman with a long history of double-kidney transplantation complained of frequent urinary tract infections, a history of vague loin pain and came to our attention for sonography follow-up. Her kidney function was normal, we did not find signs of infections in the transplanted kidneys and urinary findings were normal. Curiously, the transplanted kidneys came from a newborn and the patient received a double-kidney transplantation in order to guarantee a satisfactory renal function.
Conclusions
Despite a long history of kidney transplantation, genetic disease should not be forgotten when symptoms and images recall to specific inherited alterations. Sonography has to be considered in diagnostic path of kidney cystic disease.

Abstract
Healthcare workers (HCW) are at high risk for suicide, yet little is known about the onset of suicidal thoughts and behaviors (STB) in this important segment of the population in conjunction with the COVID-19 pandemic. We conducted a multicenter, prospective cohort study of Spanish HCW active during the COVID-9 pandemic. A total of n = 4809 HCW participated at baseline (May-September 2020; i.e., just after the first wave of the pandemic) and at a four-month follow-up assessment (October-December 2020) using web-based surveys. Logistic regression assessed the individual- and population-level associations of separate proximal (pandemic) risk factors with four-month STB incidence (i.e., 30-day STB among HCW negative for 30-day STB at baseline), each time adjusting for distal (pre-pandemic) factors. STB incidence was estimated at 4.2% (SE = 0.5; n = 1 suicide attempt). Adjusted for distal factors, proximal risk factors most strongly associated with STB incidence were various sources of interpersonal stress (scaled 0-4; odds ratio [OR] range = 1.23-1.57) followed by personal health-related stress and stress related to the health of loved ones (scaled 0-4; OR range 1.30-1.32), and the perceived lack of healthcare center preparedness (scaled 0-4; OR = 1.34). Population-attributable risk proportions for these proximal risk factors were in the range 45.3-57.6%. Other significant risk factors were financial stressors (OR range 1.26-1.81), isolation/quarantine due to COVID-19 (OR = 1.53) and having changed to a specific COVID-19 related work location (OR = 1.72). Among other interventions, our findings call for healthcare systems to implement adequate conflict communication and resolution strategies and to improve family-work balance embedded in organizational justice strategies.

Abstract
In December 2019, a novel coronavirus emerged in Wuhan, China, rapidly spreading into a global pandemic. Italy was the first European country to experience SARS-CoV-2 epidemic, and one of the most severely affected during the first wave of diffusion. In contrast to the general restriction of people movements in Europe, the number of migrants arriving at Italian borders via the Mediterranean Sea route in the summer of 2020 had increased dramatically, representing a possible, uncontrolled source for the introduction of novel SARS-CoV-2 variants. Importantly, most of the migrants came from African countries showing limited SARS-CoV-2 epidemiological surveillance. In this study, we characterized the SARS-CoV-2 genome isolated from an asymptomatic migrant arrived in Sardinia via the Mediterranean route in September 2020, in comparison with SARS-CoV-2 isolates arrived in Sicily through the Libyan migration route; with SARS-CoV-2 isolates circulating in Sardinia during 2020; and with viral genomes reported in African countries during the same summer. Results showed that our sequence is not phylogenetically related to isolates from migrants arriving in Sicily, nor to isolates circulating in Sardinia territory, having greater similarity to SARS-CoV-2 genomes reported in countries known for being sites of migrant embarkation to Italy. This is in line with the hypothesis that most SARS-CoV-2 infections among migrants have been acquired prior to embarking to Italy, possibly during the travel to or the stay in crowded Libyan immigrant camps. Overall, these observations underline the importance of dedicated SARS-CoV-2 surveillance of migrants arriving in Italy and in Europe through the Mediterranean routes.

Abstract
INTRODUCTION To analyze the virus spread among Sassari Hospital staff in the first Covid-19 wave and the impact of the Swab Team, a multidisciplinary task force entitled of nasopharyngeal swab collection and testing. METHODOLOGY Nasopharyngeal swabs from HCWs between March 6 and May 28 2020 are evaluated. RESULTS 4919 SARS-CoV-2 tests were performed on 3521 operators. Nurses and doctors are the categories at highest risk. After the Swab Team institution, the average number of swabs raised from 47/day to 86/day (p = 0.007). Positive samples decreased from 18.6% to 1.7% (p < 0.0001). CONCLUSIONS The Swab Team is effective in increasing the cases tested and in reducing the reporting time. Procedure standardization reduces the risk for all the subjects involved (no transmission among swab team members, nor during the sample collection).

Abstract
Abstract
Background
Incessant pericarditis is defined as pericarditis with persistent symptoms without a symptom-free interval of 4 to 6 weeks despite therapy. On the contrary, recurrent pericarditis is characterized by recurring symptoms after a symptom-free interval of at least 4 to 6 weeks, allowing the completion of therapy.
Aims
The aim of this study is to assess the risk of complicated pericarditis and related hospitalizations according to the clinical pattern of incessant or recurrent pericarditis.
Methods
From January 2017 to December 2018, all consecutive patients admitted to AOU Città della Salute (Turin, IT) for pericarditis were included in a prospective cohort study with a clinical and echocardiographic follow-up at 1, 3, and 6 months, and then every 6 months.
Results
We included 147 patients (median age, 50.9 years [IQR, 28.5]; 49.7% women, 89% had idiopathic aetiology, 11% had pericarditis related to systemic inflammatory disease/postcardiac injury syndrome, 80% had pericardial effusion, and 62% had elevated C-reactive protein >5 mg/L). Patients were treated according to ESC guidelines. After a median follow-up of 14 months (IQR, 9 months), adverse events were recorded in 54/147 patients (36.7%): nonidiopathic/viral aetiology in 16 of 147 cases (10.9%), recurrent pericarditis/persistent symptoms in 53 of 147 cases (36.1%), cardiac tamponade in 4/147 cases (2.7%), persistent CP in 4/147 cases (2.7%), and hospitalization related to pericarditis in 38/147 cases (25.9%). An incessant course was reported in 18 of 147 cases (12%). The risk of complications was higher in patients with incessant pericarditis (Figure) – especially CP – compared to nonincessant course (22.2% versus 0%, respectively; P<0.001). Patients with incessant pericarditis more commonly had echocardiographic evidence of CP (77.8% vs. 9.3%; P<0.001) and thickened pericardium on multimodality imaging (66.7% vs. 4.7%; P<0.001). These findings were reversible with medical therapy with the use of anakinra (100 mg/d) and colchicine in all but 4 cases that progressed to persistent CP, which were referred for pericardiectomy. An analysis of risk factors for complicated pericarditis and hospitalization using Cox proportional hazards regression analysis identified the following risk factors: large pericardial effusion (hazard ratio, 7.63 [95% CI, 3.09–18.83]), elevated C-reactive protein >5 mg/L (hazard ratio, 5.55 [95% CI, 1.87–16.44]), and incessant course (HR, 17.10 [95% CI, 7.63–38.33]).
Conclusions
This study highlights that an incessant course of pericarditis is a possible new risk factor for complications and especially for developing constriction. In clinical practice, the detection of an incessant course, as well as imaging findings of constriction and pericardial thickening, should prompt more diagnostic testing, a close follow-up, and more aggressive therapy to prevent complications and persistent constriction.

Abstract
BACKGROUND During the COVID-19 outbreak, a very high number of infected patients developed pneumonia and many of them complicated with acute respiratory distress syndrome. The optimal management of respiratory failure and the role of lung ultrasound imaging in the evaluation of efficacy of treatment are unknown. METHODS In March 2020 we treated 18 patients with mild and moderate ARDS secondary to SARS-CoV-2 with non-invasive continuous positive airway pressure therapy (NI-CPAP). All patients underwent lung ultrasound imaging to verify the entity of lung recruitment after NI-CPAP initiation. RESULTS After one hour of treatment we observed a significant improvement in PaO2/FiO2 ratio in 10 patients. Notably, only 50 % of them reached an effective improvement in lung aeration detectable with lung ultrasound. In the other 50 % or patients the improvement in PaO2/FiO2 might be related to blood redistribution and reverse of hypoxic vasoconstriction. CONCLUSION NI- CPAP is a valid therapeutic option in mild and moderate ARDS secondary SARS-CoV-2. Lung recruitment detected by means of lung ultrasound is a relevant but not the exclusive mechanism that underlies the therapeutic efficacy of NI-CPAP in this clinical setting.

Abstract
The complex non-linear regime of the monthly rainfall in Catalonia (NE Spain) is analyzed by means of the reconstruction fractal theorem and the multifractal detrended fluctuation analysis algorithm. Areas with a notable degree of complex physical mechanisms are detected by using the concepts of persistence (Hurst exponent), complexity (embedding dimension), predictive uncertainty (Lyapunov exponents), loss of memory of the mechanism (Kolmogorov exponent), and the set of multifractal parameters (Hölder exponents, spectral asymmetry, spectral width, and complexity index). Besides these analyses permitting a detailed description of monthly rainfall pattern characteristics, the obtained results should also be relevant for new research studies concerning monthly amounts forecasting at a monthly scale. On one hand, the number of necessary monthly data for autoregressive processes could change with the complexity of the multifractal structure of the monthly rainfall regime. On the other hand, the discrepancies between real monthly amounts and those generated by some autoregressive algorithms could be related to some parameters of the reconstruction fractal theorem, such as the Lyapunov and Kolmogorov exponents.

Abstract
OBJECTIVE SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)-related pneumonia, referred to as COVID-19 (Coronavirus Disease 19), is a public health emergency as it carries high morbidity, mortality, and has no approved specific pharmacological treatments. In this case series, we aimed to report preliminary data obtained with anti-complement C5 therapy with eculizumab in COVID-19 patients admitted to intensive care unit (ICU) of ASL Napoli 2 Nord. PATIENTS AND METHODS This is a case series of patients with a confirmed diagnosis of SARS-CoV2 infection and severe pneumonia or ARDS who were treated with up to 4 infusions of eculizumab as an off-label agent. Patients were also treated with anticoagulant therapy with Enoxaparin 4000 IU/day via subcutaneous injection, antiviral therapy with Lopinavir 800 mg/day + Ritonavir 200 mg/day, hydroxychloroquine 400 mg/day, ceftriaxone 2 g/day IV, vitamine C 6 g/day for 4 days, and were on Non-Invasive Ventilation (NIV). RESULTS We treated four COVID-19 patients admitted to the intensive care unit because of severe pneumonia or ARDS. All patients successfully recovered after treatment with eculizumab. Eculizumab induced a drop in inflammatory markers. Mean C Reactive Protein levels dropped from 14.6 mg/dl to 3.5 mg/dl and the mean duration of the disease was 12.8 days. CONCLUSIONS Eculizumab has the potential to be a key player in treatment of severe cases of COVID-19. Our results support eculizumab use as an off-label treatment of COVID-19, pending confirmation from the ongoing SOLID-C19 trial.

Abstract
BACKGROUND Metastatic pancreatic cancer has a median overall survival of less than 12 months, even if treated with chemotherapy. Selected patients with oligometastatic disease could benefit from multimodal treatments connecting chemotherapy and surgical treatment or radiofrequency ablation (RFA) of metastases. CASE PRESENTATION We present a patient with oligometastatic pancreatic cancer recurrence who was successfully treated with a multimodal therapeutic approach. A 57-year-old male initially presenting with resectable pancreatic cancer underwent pancreatoduodenectomy. The histopathological diagnosis revealed ductal pancreatic adenocarcinoma with positive surgical resection margins and negative lymph nodes. He completed six cycles of adjuvant therapy with gemcitabine (1000 mg/mq 1,8,15q 28), followed by external radiotherapy (54 Gy in 25 fractions) associated with gemcitabine 50 mg/mq twice weekly. Three years later, the patient developed multiple liver metastases, and he started FOLFIRINOX (oxaliplatin 85 mg/mq, irinotecan 180 mg/mq, leucovorin 400 mg/mq and fluorouracil 400 mg/mq given as a bolus followed by 2400 mg/mq as a 46 h continuous infusion,1q 14) as a first-line treatment. The CT scan showed a partial response after 6 cycles. After multidisciplinary discussion, the patient underwent a laparotomic metastasectomy of the three hepatic lesions. After additional postsurgical chemotherapy with 4 cycles of the FOLFIRINOX schedule, the patient remained free of recurrence for 12 months. A CT scan showed a new single liver metastasis, which was treated with radiofrequency ablation (RFA). A second radiofrequency ablation was performed when the patient developed another single liver lesion 12 months after the first RFA; currently, the patient is free from recurrence with an overall survival of 6 years from the diagnosis. CONCLUSIONS Our case has benefited from successful multimodal treatment, including surgical and local ablative techniques and systemic chemotherapy. A multimodal approach may be warranted in selected patients with oligometastatic pancreatic cancer and could improve overall survival. Further research is needed to investigate this approach.

Abstract
Point-of-care ultrasound (POCUS) is increasingly used to assess medical patients. It has many uses in daily clinical practice, including improved diagnostic timeliness and accuracy, and providing information about a patient's prognosis and follow-up. It has been integrated into numerous specialities, but remains relatively undefined in internal medicine training programs. Ultrasonography is a useful tool in the standard clinical practice of internists in numerous clinical scenarios (Emergency Department, hospital ward, general and specific consultations, and home care). Although POCUS has been recently included in the European curriculum of internal medicine, there are differences between European internists in its use, ranging from not at all to well structured educational programs. The use of POCUS needs to be widespread in internal medicine departments, and to accomplish this we must encourage structured training. This document details the consensus-based recommendations by the European Federation of Internal Medicine (EFIM) Ultrasound working group. We establish POCUS core competencies and clinical settings for internists in a symptom-based approach. We also propose training requirements, providing a framework for training programs at a national level.

Abstract
As of 28 February 2020, Italy had 888 cases of SARS-CoV-2 infections, with most cases in Northern Italy in the Lombardia and Veneto regions. Travel-related cases were the main source of COVID-19 cases during the early stages of the current epidemic in Italy. The month of February, however, has been dominated by two large clusters of outbreaks in Northern Italy, south of Milan, with mainly local transmission the source of infections. Contact tracing has failed to identify patient zero in one of the outbreaks. As of 28 February 2020, twenty-one cases of COVID-19 have died. Comparison between case fatality rates in China and Italy are identical at 2.3. Additionally, deaths are similar in both countries with fatalities in mostly the elderly with known comorbidities. It will be important to develop point-of-care devices to aid clinicians in stratifying elderly patients as early as possible to determine the potential level of care they will require to improve their chances of survival from COVID-19 disease.

Abstract
BACKGROUND Since 1985, two antigenically distinct lineages of influenza B viruses (Victoria-like and Yamagata-like) have circulated globally. Trivalent seasonal influenza vaccines contain two circulating influenza A strains but a single B strain and thus provide limited immunity against circulating B strains of the lineage not included in the vaccine. In this study, we describe the characteristics of influenza B viruses that caused respiratory illness in the population in Italy over 13 consecutive seasons of virological surveillance, and the match between the predominant influenza B lineage and the vaccine B lineage, in each season. METHODS From 2004 to 2017, 26,886 laboratory-confirmed influenza cases were registered in Italy, of which 18.7% were type B. Among them, the lineage of 2465 strains (49%) was retrieved or characterized in this study by a real-time RT-PCR assay and/or sequencing of the hemagglutinin (HA) gene. RESULTS Co-circulation of both B lineages was observed each season, although in different proportions every year. Overall, viruses of B/Victoria and B/Yamagata lineages caused 53.3 and 46.7% of influenza B infections, respectively. A higher proportion of infections with both lineages was detected in children, and there was a declining frequency of B/Victoria detections with age. A mismatch between the vaccine and the predominant influenza B lineage occurred in eight out of thirteen influenza seasons under study. Considering the seasons when B accounted for > 20% of all laboratory-confirmed influenza cases, a mismatch was observed in four out of six seasons. Phylogenetic analysis of the HA1 domain confirmed the co-circulation of both lineages and revealed a mixed circulation of distinct evolutionary viral variants, with different levels of match to the vaccine strains. CONCLUSIONS This study contributes to the understanding of the circulation of influenza B viruses in Italy. We found a continuous co-circulation of both B lineages in the period 2004-2017, and determined that children were particularly vulnerable to Victoria-lineage influenza B virus infections. An influenza B lineage mismatch with the trivalent vaccine occurred in about two-thirds of cases.

Abstract
Colorectal cancer (CRC) ranks as the most frequent carcinoma worldwide. CRC patients show strong prognostic differences and responses to treatment, and 20% have incurable metastatic disease at diagnosis. We considered it essential to investigate mechanisms that control cellular regulatory networks, such as the miRNA-mRNA interaction, known to be involved in cancer pathogenesis. We conducted a human miRNome analysis by TaqMan low density array, comparing CRC to normal colon tissue (NCT, and experimentally identified gene targets of miRNAs deregulated, by anti-correlation analysis, with the CRC whole-transcriptome profile obtained from RNASeq experiments. We identified an integrated signature of 20 deregulated miRNAs in CRC. Enrichment analyses of the gene targets controlled by these miRNAs brought to light 25 genes, members of pathways known to lead to cell growth and death (CCND1, NKD1, FZD3, MAD2L1, etc.), such as cell metabolism (ACSL6, PRPS1-2). A screening of prognosis-mediated miRNAs underlined that the overexpression of miR-224 promotes CRC metastasis, and is associated with high stage and poor survival. These findings suggest that the biology and progression of CRC depend on deregulation of multiple miRNAs that cause a complex dysfunction of cellular molecular networks. Our results have further established miRNA-mRNA interactions and defined multiple pathways involved in CRC pathogenesis.

Abstract
INTRODUCTION Renal allograft biopsy is the gold standard for the detection of histological lesions of chronic allograft dysfunction. The identification of a noninvasive routine test would be desirable. Elastosonography is used to assess tissue stiffness according to viscosity, and no data are available on the use of point quantification shear-wave elastography (ElastPQ) for the evaluation of renal chronic lesions. RESEARCH QUESTION To evaluate the feasibility of ElastPQ to assess cortical allograft stiffness and to determine the correlation of clinical, biological, and pathological factors with the diagnostic accuracy of kidney stiffness values in patients with histological lesions. DESIGN Forty-two patients underwent kidney transplant biopsy and 10 valid measurements of ElastPQ, blindly performed by 2 operators. The interobserver reproducibility was assessed according to intraclass correlation coefficient. The ElastPQ measurements and the clinical data were compared using the Spearman correlation analysis. RESULTS 97.6% reliable measurements were obtained using ElastPQ, with an excellent interobserver agreement. The kidney stiffness was significantly higher in the patients with a time since transplantation >12 months and was correlated with chronic lesions (interstitial fibrosis, tubular atrophy transplant glomerulopathy, and mesangial matrix), with the interstitial fibrosis/tubular atrophy, score and with the sum of the scores of the chronic lesions. Mesangial matrix increase is the only independent determinant of kidney stiffness. DISCUSSION ElastPQ is a noninvasive, reproducible, and sensitive diagnostic tool able to detect moderate/severe chronic lesions. Its routine use during follow-up can identify patients eligible for biopsy, which remains the gold standard exam for detecting chronic allograft dysfunction.

Abstract
Colorectal cancer (CRC) is a leading cause of cancer death worldwide and about 20% is metastatic at diagnosis and untreatable. The anti-EGFR therapy in metastatic patients is led by the presence of KRAS-mutations in tumor tissue. KRAS-wild-type CRC patients showed a positive response rate of about 70% to cetuximab or panitumumab combined with chemotherapy. MiRNAs are promising markers in oncology and could improve our knowledge on pathogenesis and drug resistance in CRC patients. This class of molecules represents an opportunity for the development of miRNA-based strategies to overcome the ineffectiveness of anti-EGFR therapy. We performed an integrative analysis of miRNA expression profile between KRAS-mutated CRC and KRAS-wildtype CRC and paired normal colic tissue (NCT). We revealed an overexpression of miR-425-5p in KRAS-mutated CRC compared to KRAS-wild type CRC and NCT and demonstrated that miR-425-5p exerts regulatory effects on target genes involved in cellular proliferation, migration, invasion, apoptosis molecular networks. These epigenetic mechanisms could be responsible of the strong aggressiveness of KRAS-mutated CRC compared to KRAS-wildtype CRC. We proved that some miR-425-5p targeted genes are involved in EGFR tyrosine kinase inhibitor resistance pathway, suggesting that therapies based on miR-425-5p may have strong potential in targeting KRAS-driven CRC. Moreover, we demonstrated a role in the oncogenesis of miR-31-5p, miR-625-5p and miR-579 by comparing CRC versus NCT. Our results underlined that miR-425-5p might act as an oncogene to participate in the pathogenesis of KRAS-mutated CRC and contribute to increase the aggressiveness of this subcategory of CRC, controlling a complex molecular network.

Abstract
Sarcomas comprise a broad group of tumors, many of whose biological behavior and aggressiveness differ from one type to another. The therapeutic approach is generally multidisciplinary and often complex. Developments in surgical and oncological dermatology during the last few decades have positioned dermatologists as specialists in the diagnosis and treatment of skin cancer. The aim of this article is to review the main soft tissue sarcomas that typically affect the skin. Dermatofibrosarcoma protuberans is a low-grade malignant sarcoma. It exhibits slow-growth, is locally invasive, and has low metastatic potential (<3%). Mohs micrographic surgery is the treatment of choice. The COL1A1-PDGFB translocation should be analyzed in cases of unclear diagnosis and when it is necessary to identify candidates for tyrosine kinase inhibitors. Imatinib is indicated for the treatment of locally advanced and metastatic dermatofibrosarcoma protuberans.

Abstract
From September 1986 to April 1988, all consecutive patients with histologically proven (pathologic review mandatory) malignant mesothelioma, measurable disease, age less than 75 years, Karnofsky performance status equal to or greater than 40, and no previous chemotherapy were treated with epiru-blcin at the dosage of 75 mg/m2 i.v. every 3 weeks. Of the 23 patients who entered the study, 2 were retrospectively found not to have malignant mesothelioma. In the 21 eligible patients (all evaluable), no complete remission, 1 partial remission, 11 stable diseases and 9 progressions were noted. Toxicity was very mild. Median survival was 7.5 months. At the dosage used, epirubicin proved to be of little value in the management of these patients. Whether higher doses are more effective, as has been noted in other tumors, remains to be ascertained.

Abstract
Background The aim of this study was to evaluate the pepsinogen C expression in malignant cutaneous melanomas and analyze its possible relationship to clinical and pathological parameters. Pepsinogen C is an aspartyl proteinase primarily involved in the digestion of proteins in the stomach and represents one of the main androgen-inducible proteins in breast cancer cells. Method Tumoral pepsinogen C expression was retrospectively analyzed in 35 paraffin-embedded tissues from patients with primary malignant cutaneous melanoma and in 10 samples from 10 benign lesions (4 dermal melanocytic nevi, 4 compound melanocytic nevi and 2 dysplastic melanocytic nevi), using immunohistochemical methods. Results The benign lesions were consistently negative for pepsinogen C, whereas 20 of the 35 malignant melanomas (57%) showed positive immunostaining for pepsinogen C. The percentage of pepsinogen C-positive tumors was significantly higher in men than in women (p=0.01) and in epithelioid melanomas than in fusocellular or mixed type melanomas (p=0.003). In addition, the percentage of pepsinogen-C positive tumors was positively and significantly correlated with lesion thickness (p=0.003), Clark's level of invasion (p=0.028) and tumor stage (p<0.001). Conclusion Pepsinogen C could be a new prognosticator of unfavorable outcome in cutaneous malignant melanoma.

Abstract
Abstract
Background
When comparing the efficacy of surgical and non-surgical therapies for hepatocellular carcinoma (HCC), a major limitation is the causal inference problem. This concerns the impossibility of seeing both outcomes of two different treatments for the same individual at the same time because one is inevitably missing. This aspect can be addressed methodologically by estimating the so-called average treatment effect (ATE).
Methods
To estimate the ATE of hepatic resection over locoregional therapies for HCC, data from patients treated in two tertiary care settings between August 2000 and December 2014 were used to obtain counterfactual outcomes using an inverse probability weight survival adjustment.
Results
A total of 1585 patients were enrolled: 815 underwent hepatic resection, 337 radiofrequency ablation (RFA) and 433 transarterial chemoembolization (TACE). The option of operating on all patients who had tumour ablation returned an ATE of +9·8 months for resection (effect size 0·111; adjusted P = 0·064). The option of operating on all patients who had TACE returned an ATE of +27·9 months (effect size 0·383; adjusted P < 0·001). The ATE of surgery was negligible in patients undergoing ablation for very early HCCs (effect size 0·027; adjusted P = 0·627), independently of albumin–bilirubin (ALBI) grade; or in patients with ALBI liver function grade 2 (effect size 0·083; adjusted P = 0·213), independently of tumour stage. In all other instances, the ATE of surgery was notably greater. Operating on patients who had TACE with multinodular HCC beyond the Milan criteria resulted in a mild ATE (effect size 0·140; adjusted P = 0·037).
Conclusion
ATE estimation suggests that hepatic resection is a better treatment option than ablation and TACE in patients with HCC.

Abstract
An important factor affecting the success in the setting of related haploidentical hematopoietic stem cell transplantation (HSCT) is the graft-versus-leukemia effect mediated by natural killer (NK) cells when the donor displays NK alloreactivity versus the recipient. NK cell function is regulated by killer immunoglobulin-like receptors (KIR) and it has been described that donor KIR genotype influences transplantation outcome. This has led to a requirement of laboratories to have a quality assurance program for validation and control of their KIR genotyping methods. The goal of the 1st and 2nd Spanish KIR Genotyping Workshops was to provide an external proficiency testing program in KIR genotyping for Spanish immunology and transplant laboratories. These workshops were conducted during the years 2014-2016 and consisted of 17 participating laboratories typing a set of 20 samples. The presence/absence of 16 mandatory KIR loci (2DL1, 2DL2, 2DL3, 2DL4, 2DL5, 2DS1, 2DS2, 2DS3, 2DS4, 2DS5, 2DP1, 3DL1, 3DL2, 3DL3, 3DS1, and 3DP1) was evaluated per sample. Methods for KIR genotyping included polymerase chain reaction with the use of sequence-specific primers and sequence-specific oligoprobes. Consensus typing was reached in all samples, and the performance of laboratories in external proficiency testing was satisfactory in all cases. The polymorphism detected in the small sample studied in both workshops is indicative of an ample variety of KIR gene profiles in the Spanish population.

Abstract
During the past two decades, several studies showed reduced rates of hepatocellular carcinoma recurrence in patients with HCV-related cirrhosis after interferon-based antiviral therapies respect to untreated controls, even without reaching viral clearance. The recent development of new all-oral regimens with direct-acting antivirals has radically improved the therapeutic management of hepatitis C. Nevertheless, paradoxical, or at least unexpected, high rates of both occurrence and recurrence of hepatocellular carcinoma after a treatment with direct-acting antivirals, have been reported in the recent literature. These findings generated a strong rebound in the hepatology community and are at present still controversial. We sought to compare the hepatocellular carcinoma recurrence-free survival of a historical cohort treated with pegylated interferon/ribavirin and an untreated cohort with a cohort treated with direct-acting antivirals.

Abstract
Natalizumab is effective against multiple sclerosis (MS), but is associated with progressive multifocal leukoencephalopathy (PML), fatal disease caused by the JCV polyomavirus. The SF2/ASF (splicing factor2/alternative splicing factor) inhibits JCV in glial cells. We wondered about SF2/ASF modulation in the blood of natalizumab-treated patients and if this could influence JCV reactivation. Therefore, we performed a longitudinal study of MS patients under natalizumab, in comparison to patients under fingolimod and to healthy blood donors. Blood samples were collected at time intervals. The expression of SF2/ASF and the presence and expression of JCV in PBMC were analyzed. A bell-shaped regulation of SF2/ASF was observed in patients treated with natalizumab, increased in the first year of therapy, and reduced in the second one, while slightly changed, if any, in patients under fingolimod. Notably, SF2/ASF was up-regulated, during the first year, only in JCV DNA-positive patients, or with high anti-JCV antibody response; the expression of the JCV T-Ag protein in circulating B cells was inversely related to SF2/ASF protein expression. The SF2/ASF reduction, parallel to JCV activation, during the second year of therapy with natalizumab, but not with fingolimod, may help explain the increased risk of PML after the second year of treatment with natalizumab, but not with fingolimod. We propose that SF2/ASF has a protective role against JCV reactivation in MS patients. This study suggests new markers of disease behavior and, possibly, help in re-evaluations of therapy protocols.

Abstract
One prognostic factor for early multiple sclerosis (MS) patients to develop a definite MS may be the presence of the MS-associated retrovirus (MSRV) in the cerebrospinal fluid (CSF). We designed a specific study on a cohort of optic neuritis (ON) patients to evaluate the MSRV-dependent conversion to MS relative to the prediction conferred by magnetic resonance imaging (MRI) and CSF abnormalities. At follow-up, 33.3% MSRV+ and 0% MSRV− ON patients developed MS ( P=0.03). The prediction value is lower than that given by CSF and MRI abnormalities (42.3%). This intriguing finding is discussed in the light of the abundant discrepancies observed in the MSRV literature.

Abstract
The human endogenous retroviruses (HERV)-W family contains an extracellular particle detected in multiple sclerosis (MS) patients and designated as MS-associated retrovirus (MSRV). Through nested RT-PCR assays specific for pol MSRV gene, we preliminary reported that its presence in the cerebrospinal fluid (CSF) of early MS patients could be indicative of a poor prognosis upon a three-year follow-up. In the present clinical study, we enlarged our blind observation up to six years. At study entry, 10 MS patients were MSRV- and eight were MSRV+ in the CSF, both groups having a similar mean age and Expanded Disability Status Scale (EDSS) score. After six year follow-up, the mean EDSS significantly differed between the MSRV- and MSRV+ cohorts (4.3 versus 2.2; P = 0.004), as did the annual relapse rate (0.5 in the MSRV- versus 0.3 in the MSRV+; P = 0.01). Finally, two MSRV- patients entered the progressive phase, whilst none of the MSRV+ group entered this phase, and 9/10 MSRV- versus 2/8 MSRV+ patients were treated with immunomodulatory or immunosuppressive drugs (P = 0.009). In conclusion, we found that the presence of MSRV virions in the CSF at the onset of MS is associated, not only with disability accumulation, but also with a higher rate of clinical re-exacerbations. With the known potential pathogenic effects of MSRV given in the literature, further investigations on MSRV are warranted.

Abstract
BACKGROUND Cancer risk in secondary aluminium production is not well described. Workers in this industry are exposed to potentially carcinogenic agents from secondary smelters that reprocess aluminium scrap. AIMS To evaluate cancer risk in workers in a secondary aluminium plant in Spain. METHODS Retrospective cohort study of male workers employed at an aluminium secondary smelter (1960-92). Exposure histories and vital status through 2011 were obtained through personal interviews and hospital records, respectively. Standardized mortality (SMRs) and incidence ratios (SIRs) were calculated. RESULTS The study group consisted of 98 workers. We found increased incidence and mortality from bladder cancer [SIR = 2.85, 95% confidence interval (CI) 1.23-5.62; SMR = 5.90, 95% CI 1.58-15.11]. Increased incidence was also observed for prostate cancer and all other cancers but neither were statistically significant. No increased risk was observed for lung cancer. CONCLUSIONS Results of this study suggest that work at secondary aluminium smelters is associated with bladder cancer risk. Identification of occupational carcinogens in this industry is needed.
