This interview describes the numerous and important contributions that Vito Cagli, who was born in Ancona in 1926, has given to the Italian Nephrology and to other fields of Medicine. These contributions, that are very poorly known today, were produced especially in the years in which Cagli worked as deputy director of the Centre for the Investigation and Treatment of Hypertension and Renal Diseases at Policlinico Hospital Umberto I in Rome. This interview also describes the early phase of Italian Nephrology before the introduction in our country of renal biopsy and of hemodialysis.

Background & Aims Obeticholic acid (OCA) has recently been restricted in patients with primary biliary cholangitis (PBC) with "advanced cirrhosis" because of its narrow therapeutic index. We aimed to better define the predicting factors of hepatic serious adverse events (SAEs) and non-response in cirrhotic patients undergoing OCA therapy. Methods Safety and efficacy of treatment were evaluated in a cohort of consecutive PBC cirrhotic patients started with OCA. OCA response was evaluated according to the Poise criteria. Risk factors for hepatic SAEs and non-response were reported as risk ratios (RR) with 95% confidence intervals (CIs). Results One hundred PBC cirrhotics were included, 97 Child-Pugh class A and 3 class B. Thirty-one had oesophageal varices and 5 had a history of ascites. Thirty-three per cent and 32% of patients achieved a biochemical response at 6 and 12 months respectively. Male sex (adjusted-RR 1.75, 95%CI 1.42-2.12), INR (1.37, 1.00-1.87), Child-Pugh score (1.79, 1.28-2.50), MELD (1.17, 1.04-1.30) and bilirubin (1.83, 1.11-3.01) were independently associated with non-response to OCA. Twenty-two patients discontinued OCA within 12 months: 10 for pruritus, 9 for hepatic SAEs (5 for jaundice and/or ascitic decompensation; 4 for upper digestive bleeding). INR (adjusted-RR 1.91, 95%CI 1.10-3.36), lower albumin levels (0.18, 0.06-0.51), Child-Pugh score (2.43, 1.50-4.04), history of ascites (3.5, 1.85-6.5) and bilirubin (1.30, 1.05-1.56), were associated with hepatic SAEs. A total bilirubin >= 1.4 mg/dl at baseline was the most accurate biochemical predictor of hepatic SAEs under OCA. Conclusions An accurate baseline assessment is crucial to select cirrhotic patients who can benefit from OCA. Although OCA is effective in one third of cirrhotics, bilirubin level >= 1.4 mg/dl should discourage from its use.

Toll-like receptors (TLRs) regulate innate and adaptive immune responses. Moreover, TLRs can induce a pro-survival and pro-proliferation response in tumor cells. This study aims to investigate the expression of TLR4 in the epithelium surrounding oral squamous cell carcinomas (OSCC) in relation to its inflammatory microenvironment. This study included 150 human samples: 30 normal oral control (NOC), 38 non-lichenoid epithelium surrounding OSCC (NLE-OSCC), 28 lichenoid epithelium surrounding OSCC (LE-OSCC), 30 OSCC ex-non oral lichenoid lesion (OSCC Ex-NOLL), and 24 OSCC ex-oral lichenoid lesion (OSCC Ex-OLL). TLR4 expression was investigated by immunohistochemistry and the percentage of positive cells was quantified. In addition, a semiquantitative analysis of staining intensity was performed. Immunohistochemical analysis revealed that TLR4 is strongly upregulated in LE-OSCC as compared to normal control epithelium and NLE-OSCC. TLR4 expression was associated with the inflammatory environment, since the percentage of positive cells increases from NOC and NLE-OSCC to LE-OSCC, reaching the highest value in OSCC Ex–OLL. TLR4 was detected in the basal third of the epithelium in NLE-OSCC, while in LE-OSCC, TLR4 expression reached the intermediate layer. These results demonstrated that an inflammatory microenvironment can upregulate TLR4, which may boost tumor development.

Low-grade serous ovarian and peritoneal cancer (LGSC) is a rare disease and few data on the clinical and genomic landscape have been published.A retrospective analysis of patients diagnosed with LGSC between 1996 and 2019 was conducted in MITO centers. Objective Response Rate (ORR) to treatments, progression-free survival (PFS) and overall survival (OS) were assessed. Additionally, the tumor molecular profile of 56 patients was evaluated using the Next Generation Sequencing (NGS) FoundationOne CDX (Foundation Medicine®).A total of 128 patients with complete clinical data and pathologically confirmed diagnosis of LGSC were identified. ORR to first and subsequent therapies were 23.7% and 33.7%, respectively. PFS was 43.9 months (95% CI:32.4-53.1) and OS was 105.4 months (95% CI: 82.7-not reached). The most common gene alterations were: KRAS (n = 12, 21%), CDKN2A/B (n = 11, 20%), NRAS (n = 8, 14%), FANCA (n = 8, 14%), NF1 (n = 7, 13%) and BRAF (n = 6, 11%). Unexpectedly, pathogenetic BRCA1 (n = 2, 4%), BRCA2 (n = 1, 2%) and PALB2 (n = 1, 2%) mutations were found.MITO 22 suggests that LGSC is an heterogenous disease for both its clinical behavior in response to standard therapies and its molecular alterations. Future prospective studies should test treatments according to biological and molecular tumor's characteristics.This study is registered under NCT02408536 on ClinicalTrials.gov .

Tumors of nasal cavity and paranasal sinuses (TuNSs) are rare and heterogeneous malignancies, presenting different histological features and clinical behavior. We reviewed the literature about etiology, biology, and clinical features of TuNSs to define pathologic features and possible treatment strategies. From a diagnostic point of view, it is mandatory to have high expertise and perform an immunohistochemical assessment to distinguish between different histotypes. Due to the extreme rarity of these neoplasms, there are no standard and evidence-based therapeutic strategies, lacking prospective and large clinical trials. In fact, most studies are retrospective analyses. Surgery represents the mainstay of treatment of TuNSs for small and localized tumors allowing complete tumor removal. Locally advanced lesions require more demolitive surgery that should be always followed by adjuvant radio- or chemo-radiotherapy. Recurrent/metastatic disease requires palliative chemo- and/or radiotherapy. Many studies emphasize the role of specific genes mutations in the development of TuNSs like mutations in the exons 4–9 of the TP53 gene, in the exon 9 of the PIK3CA gene and in the promoter of the TERT gene. In the near future, this genetic assessment will have new therapeutic implications. Future improvements in the understanding of the etiology, biology, and clinical features of TuNSs are warranted to improve their management.

Objectives To evaluate oncological and reproductive outcomes of women undergoing fertility-sparing surgery (FSS) for stage II–III serous borderline ovarian tumors (BOTs). Methods A multi-institutional retrospective study was conducted within the MITO Group. Results A total of 91 patients were recruited. The median follow-up time from primary cytoreduction was 127 months (IQR range 91–179). Forty-nine patients (53.8%) experienced at least one recurrence (median time to first relapse 22 months, IQR range 9.5–57). At univariable analysis, significant predictors of relapse were: size of largest extra-ovarian lesion, peritoneal cancer index, completeness of cytoreduction, type of implants. After multivariable analysis, the size of extra-ovarian lesions and the presence of invasive implants resulted as the only independent predictors of recurrence. Median disease-free survival (DFS) was 96 months (95% CI, 24.6–167.3), while median disease-specific survival (DSS) was not reached. Twenty-nine patients (31.8%) attempted to conceive: 20 (68.9%) achieved at least one pregnancy and 18 (62%) gave birth to a healthy child. At the end of the observation period, 88 patients (96.7%) showed no evidence of disease, 2 (2.2%) were alive with disease, and 1 patient (1.1%) died from BOT. Conclusions Despite the recurrence high rate, FSS provides good chances of reproductive success with no impact on DSS. The presence of invasive peritoneal implants affects the DFS but not DSS nor reproductive outcome. The risk of recurrence would not seem to be related to the ovarian preservation per se, but to the natural history of the initial peritoneal spread.

Background A growing body of observational evidence supports the value of ceftazidime-avibactam (CAZ-AVI) in managing infections caused by carbapenem-resistant Enterobacteriaceae. Methods We retrospectively analyzed observational data on use and outcomes of CAZ-AVI therapy for infections caused by Klebsiella pneumoniae carbapenemase–producing K. pneumoniae (KPC-Kp) strains. Multivariate regression analysis was used to identify variables independently associated with 30-day mortality. Results were adjusted for propensity score for receipt of CAZ-AVI combination regimens versus CAZ-AVI monotherapy. Results The cohort comprised 577 adults with bloodstream infections (n = 391) or nonbacteremic infections involving mainly the urinary tract, lower respiratory tract, and intra-abdominal structures. All received treatment with CAZ-AVI alone (n = 165) or with ≥1 other active antimicrobials (n = 412). The all-cause mortality rate 30 days after infection onset was 25% (146/577). There was no significant difference in mortality between patients managed with CAZ-AVI alone and those treated with combination regimens (26.1% vs 25.0%, P = .79). In multivariate analysis, mortality was positively associated with presence at infection onset of septic shock (P = .002), neutropenia (P < .001), or an INCREMENT score ≥8 (P = .01); with lower respiratory tract infection (LRTI) (P = .04); and with CAZ-AVI dose adjustment for renal function (P = .01). Mortality was negatively associated with CAZ-AVI administration by prolonged infusion (P = .006). All associations remained significant after propensity score adjustment. Conclusions CAZ-AVI is an important option for treating serious KPC-Kp infections, even when used alone. Further study is needed to explore the drug’s seemingly more limited efficacy in LRTIs and potential survival benefits of prolonging CAZ-AVI infusions to ≥3 hours.

Objective To further delineate the electroclinical features of individuals with SYNGAP1 pathogenic variants. Methods Participants with pathogenic SYNGAP1 variants and available video-electroencephalogram (EEG) recordings were recruited within five European epilepsy reference centers. We obtained molecular and clinical data, analyzed EEG recordings and archived video-EEGs of seizures and detailed characteristics of interictal and ictal EEG patterns for every patient. Results We recruited 15 previously unreported patients and analyzed 72 EEGs. Two distinct EEG patterns emerged, both triggered by eye closure. Pattern 1 (14/15 individuals) consisted of rhythmic posterior/diffuse delta waves appearing with eye-closure and persisting until eye opening (strongly suggestive of fixation-off sensitivity). Pattern 2 (9/15 individuals) consisted of diffuse polyspike-and-wave discharges triggered by eye closure (eye-closure sensitivity). Both patterns presented in 8/15. Including archived video-EEG clips of seizures from 9/15 patients, we analyzed 254 seizures. Of 224 seizures experienced while awake, 161 (72%) occurred at or following eye closure. In 119/161, pattern 1 preceded an atypical absence, myoclonic seizure or myoclonic absence; in 42/161, pattern 2 was associated with eyelid myoclonia, absences and myoclonic or atonic seizures. Conclusions Fixation-off and eye closure were the main triggers for seizures in this SYNGAP1 cohort. Significance Combining these clinical and electroencephalographic features could help guide genetic diagnosis.

Cisplatin (CDDP) is commonly used to treat a multitude of tumors including sarcomas, ovarian and cervical cancers. Despite recent investigations allowed to improve chemotherapy effectiveness, the molecular mechanisms underlying the development of CDDP resistance remain a major goal in cancer research. Here, we show that mitochondrial morphology and autophagy are altered in different CDDP resistant cancer cell lines. In CDDP resistant osteosarcoma and ovarian carcinoma, mitochondria are fragmented and closely juxtaposed to the endoplasmic reticulum; rates of mitophagy are also increased. Specifically, levels of the mitophagy receptor BNIP3 are higher both in resistant cells and in ovarian cancer patient samples resistant to platinum-based treatments. Genetic BNIP3 silencing or pharmacological inhibition of autophagosome formation re-sensitizes these cells to CDDP. Our study identifies inhibition of BNIP3-driven mitophagy as a potential therapeutic strategy to counteract CDDP resistance in ovarian carcinoma and osteosarcoma.

Epileptic myoclonus (EM) is reported in many paediatric epilepsies from neonatal period to adolescence. Myoclonus can be the only seizure type or may occur among others, independently or in combination as a single ictal event. We report two children presenting with absences associated with myoclonus, predominating on one side, in a setting of two different types of absence seizures and two different electro-clinical syndromes. Patients were explored with long-duration video-EEG coupled to surface EMG polygraphy. EEG was visually analysed and complemented by jerk-locked back-averaging. Two types of seizure, encompassing myoclonus and absence, were identified: myoclonic absences in the context of epilepsy with myoclonic absences and atypical absences with atonic component (negative myoclonus) in the context of encephalopathy related to status epilepticus during slow sleep (ESES). In the latter case, rhythmic upper limb jerking, mimicking positive myoclonus, corresponded to recovery of muscular tone after each negative myoclonus. Due to the rhythmic recovery of muscle tone, subsequent rhythmic negative myoclonus may exhibit a similar clinical picture to that of rhythmic positive myoclonus. Video-EEG recording coupled to EMG polygraphy is essential in order to precisely characterize motor manifestations during seizures with myoclonus [Published with video sequences].

In this in vitro study, we test our hypothesis that Broccoli-derived vesicles (BDVs), combining the anti-oxidant properties of their components and the advantages of their structure, can influence the metabolic activity of different cancer cell lines. BDVs were isolated from homogenized fresh broccoli (Brassica oleracea L.) using a sucrose gradient ultracentrifugation method and were characterized in terms of physical properties, such as particle size, morphology, and surface charge by transmission electron microscopy (TEM) and laser doppler electrophoresis (LDE). Glucosinolates content was assessed by RPLC–ESI–MS analysis. Three different human cancer cell lines (colorectal adenocarcinoma Caco-2, lung adenocarcinoma NCI-H441 and neuroblastoma SHSY5Y) were evaluated for metabolic activity by the MTT assay, uptake by fluorescence and confocal microscopy, and anti-oxidant activity by a fluorimetric assay detecting intracellular reactive oxygen species (ROS). Three bands were obtained with average size measured by TEM based size distribution analysis of 52 nm (Band 1), 70 nm (Band 2), and 82 nm (Band 3). Glucobrassicin, glucoraphanin and neoglucobrassicin were found mostly concentrated in Band 1. BDVs affected the metabolic activity of different cancer cell lines in a dose dependent manner compared with untreated cells. Overall, Band 2 and 3 were more toxic than Band 1 irrespective of the cell lines. BDVs were taken up by cells in a dose- and time-dependent manner. Pre-incubation of cells with BDVs resulted in a significant decrease in ROS production in Caco-2 and NCI-H441 stimulated with hydrogen peroxide and SHSY5Y treated with 6-hydroxydopamine, with all three Bands. Our findings open to the possibility to find a novel “green” approach for cancer treatment, focused on using vesicles from broccoli, although a more in-depth characterization of bioactive molecules is warranted.

Objectives The aim of this study was to assess colistin use in a country endemic for multidrug-resistant Gram-negative bacteria (MDR-GNB). Methods Colistin prescription patterns were evaluated in 22 Italian centres. Factors associated with use of colistin in combination with other anti-MDR-GNB agents were also assessed. Results A total of 221 adults receiving colistin were included in the study. Their median age was 64 years (interquartile range 52–73 years) and 134 (61%) were male. Colistin was mostly administered intravenously (203/221; 92%) and mainly for targeted therapy (168/221; 76%). The most frequent indications for colistin therapy were bloodstream infection and lower respiratory tract infection. Intravenous colistin was administered in combination with at least another anti-MDR-GNB agent in 80% of cases (163/203). A loading dose of 9 MU of colistimethate was administered in 79% of patients receiving i.v. colistin and adequate maintenance doses in 85%. In multivariable analysis, empirical therapy [odds ratio (OR) = 3.25, 95% confidence interval (CI) 1.24–8.53;P = 0.017] and targeted therapy for carbapenem-resistant Enterobacterales infection (OR = 4.76, 95% CI 1.69–13.43; P = 0.003) were associated with use of colistin in combination with other agents, whilst chronic renal failure (OR = 0.39, 95% CI 0.17–0.88; P = 0.024) was associated with use of colistin monotherapy. Conclusion Colistin remains an important option for severe MDR-GNB infections when other treatments are not available. Despite inherent difficulties in optimising its use owing to peculiar pharmacokinetic/pharmacodynamic characteristics, colistin was mostly used appropriately in a country endemic for MDR-GNB.

Summary Objectives bloodstream infections (BSI) due to multidrug-resistant (MDR) Acinetobacter baumannii (AB) have been increasingly observed among hospitalized patients. Methods prospective, observational study conducted among 12 large tertiary-care hospitals, across 7 Italian regions. From June 2017 to June 2018 all consecutive hospitalized patients with bacteremia due to MDR-AB were included and analyzed in the study. Results During the study period 281 episodes of BSI due to MDR-AB were observed: 98 (34.8%) episodes were classified as primary bacteremias, and 183 (65.2%) as secondary bacteremias; 177 (62.9%) of them were associated with septic shock. Overall, 14-day mortality was observed in 172 (61.2%) patients, while 30-day mortality in 207 (73.6%) patients. On multivariate analysis, previous surgery, continuous renal replacement therapy, inadequate source control of infection, and pneumonia were independently associated with higher risk of septic shock. Instead, septic shock and Charlson Comorbidity Index >3 were associated with 14-day mortality, while adequate source control of infection and combination therapy with survival. Finally, septic shock, previous surgery, and aminoglycoside-containing regimen were associated with 30-day mortality, while colistin-containing regimen with survival. Conclusions BSI caused by MDR-AB represents a difficult challenge for physicians, considering the high rates of septic shock and mortality associated with this infection.

Only 10-15% of serous borderline ovarian tumors (BOTs) with extra-ovarian disease have invasive implants, and conservative treatments have been rarely reported. The MITO14 is a multi-institutional retrospective study conducted with the aim of systematically collecting data from consecutive BOT patients. The present analysis reports the oncological and reproductive outcomes of women with serous BOT and invasive implants registered into the MITO14 database and conservatively treated between August 2002 and May 2019.Thirteen patients (FIGO2014 stage II-III serous BOT with invasive implants) were recruited. Primary and secondary endpoints were, respectively, recurrence and death rates, and pregnancy and live birth rates. Only patients undergoing fertility-sparing surgery (FSS) were included, while patients were excluded in case of: age45 years; second tumor(s) requiring therapy interfering with the treatment of BOT.Median follow-up time from primary cytoreduction was 146 months (range 27-213 months). Eleven patients (84.6%) experienced at least one recurrence (median time to first relapse 17 months, range 4-190 months), all of these undergoing secondary surgery (FSS in 7). Five patients attempted to conceive: 3 achieved at least one pregnancy and 2 gave birth at least to a healthy child. At the end of the observation period, all patients were alive with no evidence of disease.Fertility-sparing treatment should be considered in a context of serous BOT with invasive implants. Despite the high rate of recurrence, FSS provides good chances of reproductive success without a negative impact on overall survival.

The Italian Fund for Alzheimer's and other dementias was approved and signed in December 2021. The Fund is financed with 15 million euros in three years. The main goal is to provide new strategies in the field of dementia with a Public Health perspective. The Fund includes eight main activities that will be monitored and supervised by the Italian National Institute of Health: 1) development of a guideline for the assessment, management and support for people with dementia and their families/carers; 2) updating of the Dementia National Plan (DNP); 3) implementation of the documents of the DNP; 4) conducting surveys dedicated to the Italian Dementia Services; 5) promotion of dementia prevention strategies; 6) training strategies for healthcare professionals, families and caregivers; 7) creation of a National Electronic Record for Dementia; 8) evaluation and monitoring of activities promoted by Regions and Autonomous Provinces in the field of dementia, together with the dementia National Permanent Table. These activities are outlined in detail in the present paper.

The First World War was a turning point for medicine worldwide and the following 20 years brought many important innovations. Kidney studies in Italy were part of this general trend. In this contribution, all the papers relating to kidney physiology, pathology and therapeutics produced by Italian scientists in the years between the two World Wars are retrieved and examined. The authors who produced strictly nephrological articles are also singled out and their activity described. This research retrieved 638 articles dealing with kidneys and published by Italian scientists over the period described. The topics covered were up-to-date, and the level was consistent with that of foreign contemporaries. Among the authors, a group of young scientists particularly dedicated to the study of the kidney emerges. Most of them would subsequently be among the founders of the Italian Society of Nephrology and leaders of Italian nephrology.

Endoscopic trans-canal tympanoplasty type I (ETT) is gradually diffusing worldwide. It mainly allows less invasive surgery in children with respect to a microscope approach by avoiding post-auricular access. The aim of this study is to illustrate our experience in endoscopic reconstruction of tympanic membrane, using autologous tragus perichondrium (TP) and non-autologous acellular porcine small intestinal sub-mucosa (SIS) as grafts.Between January 2011 and December 2020, the results of a prospective non-randomized series of consecutive ETT were analyzed. The primary outcome was closure rate at 6 months and secondary outcomes are closure rates associated with age, size of perforation, type of perforation and middle ear status, presence of myringosclerosis, type of graft, status of contralateral ear, adenoidectomy and pre-postoperative ABG change. Statistical analysis was performed using the SPSS statistical package.One hundred and sixteen consecutive procedures, mean age 9.4 years (range 4-17 years), were evaluated. TP and SIS grafts were used in 65 (56%) and 51 (44%) procedures, respectively. Mean duration of surgical procedure was 53 ± 21 min for SIS and 77 ± 18 min for TP (P = 0.001) Total graft intake was 82.8%; TP and SIS intake were 86.2% and 78.4% (P = 0.3), respectively. Graft intake w.r.t. in age stratified age groups was not statistically significant. Average preoperative and postoperative air-bone gap was 12.1 ± 7.6 dB and 5.5 ± 3.8 dB, respectively (P = 0.001). The difference in closure rates was not significant. Neither intra- nor postoperative complications were observed.In children, ETT is an applicable and less invasive technique compared to the microscope and offers less morbidity. The use of SIS contributes additional less invasiveness to endoscopic surgery by avoiding tragus harvesting with a comparable success rate and granting significantly less surgical duration.

BackgroundChemotherapy with carboplatin, paclitaxel, and bevacizumab is the standard therapy for patients with advanced stage ovarian cancer wild-type BRCA after primary surgery. The most frequent side effects of bevacizumab in this setting are hypertension, thrombosis, hemorrhage, and proteinuria, while arthralgia has been poorly described.ObjectiveTo examine the incidence, duration, and reversibility of arthralgia.Patients and methodsA retrospective analysis was performed to describe the occurrence and outcome of arthralgia in 114 patients with advanced ovarian cancer, given first-line treatment with a combination of carboplatin, paclitaxel, and bevacizumab. Statistical analysis was performed to investigate a possible prognostic role of arthralgia, with progression-free survival as endpoint.Results47 of 114 patients (41%) developed arthralgia during therapy. All patients had grade 1 or grade 2 arthralgia. Toxicity persisted after the end of bevacizumab in 17/47 patients (36%). Median progression-free survival for patients without arthralgia was 18 months (95% CI 14 to 24) compared with 29 months (95% CI 21 to not reached) for patients experiencing arthralgia (p=0.03). In order to avoid possible biases related to treatment duration, a multivariable Cox proportional hazards model including toxicity as a time dependent variable and age, stage, and residual disease after primary surgery was performed. In this model no variable showed a statistically significant association with progression-free survival.ConclusionA high incidence of arthralgia (41%) was found and although rogression-free survival was worse for those patients who developed arthralgia, this was not maintained on multivariate analysis. Guidelines for treatment of this adverse event are needed.

Objectives: To evaluate the impact of high-dose (HD) carbapenem-based combination therapy on clinical outcome in patients with monomicrobial carbapenem-resistant Klebsiella pneumoniae (CR-KP) bloodstream-infection (BSI). Methods: Post hoc analysis of all adult patients with CR-KP BSI who were treated with a combination antibiotic regimen, collected over a six-year period in six large Italian teaching hospitals. To control for confounding effects of HD carbapenem combination on 14-day mortality, a multivariate Cox regression analysis was performed. Due to imbalances between patients, a propensity score for receiving HD carbapenem was added to the model. Results: 595 patients with CR-KP BSI were analysed, 77% of isolates showed a carbapenem MIC ≥16 mg/L, 428 (71.9%) received HD carbapenem-based combination therapy. Overall, 127 patients (21.3%) died within 14 days after BSI onset. Multivariate analysis showed the Charlson comorbidity index (HR 1.31, 95%CI 1.20–1.43, P < 0.001), septic shock at BSI onset (HR 3.14, 95%CI 2.19–4.50, P < 0.001), and colistin-resistant strain (HR 1.52, 95%CI 1.02–2.24, P = 0.03) were independently associated with 14-day mortality, whereas admission to surgical ward (HR 0.44, 95%CI 0.25–0.78, P = 0.005) and HD carbapenem use (HR 0.69, 95%CI 0.47–1.00, P = 0.05) were protective factors. When adjusted for the propensity score, HD carbapenem use showed a greater protective effect (HR 0.64, 95%CI 0.43–0.95, P = 0.03). Stratifying the model for carbapenem MIC, the benefit of HD carbapenem was also observed for strains with carbapenem MIC ≥16 mg/L. Conclusions: In patients receiving combination therapy for CR-KP BSI, the use of HD carbapenem seems to be associated with better outcome, even in the presence of high-level carbapenem resistance.

Background: The achievement of high rates of sustained virological response (SVR) with direct-acting antivirals (DAAs) in hepatitis C virus (HCV) infected patients will reduce decompensating terminal events. Aims: To investigate whether hepatocellular carcinoma (HCC) occurrence could change due to the DAA-induced increase in life-expectancy. Methods: A Markov model was built on clinical data of 494 cirrhotic patients and available literature to estimate probabilities of “death before HCC” and of “HCC occurrence” without and with DAA. Results: In comparison to untreated patients, DAA therapy reduced the 20-year mortality before HCC by 21.9% in patients without varices and by 21.5% in those with varices, considering an SVR of 95% and no direct effect on hepatocarcinogenesis. Tumour occurrence increased by 5%–8.2% and the proportion of HCCs diagnosed in compensated stages increased to >98%. If we consider DAA as having “anti-tumoral” effects, the benefit becomes greater, achieving a 20-year survival of 81.5% in patients without varices, and 52.2% in patients with varices. Instead, if we consider DAA as having a “pro-tumoral” effect, then, the increased incidence of HCC nullifies the survival benefits. Conclusion: DAAs drastically reduce the mortality caused by the liver function worsening, increasing the proportion of HCCs diagnosed in compensated stages. Knowledge of the DAA effect on hepatocarcinogenesis remains pivotal. © 2017 Editrice Gastroenterologica Italiana S.r.l.

In this interview Attilio Losito tells us about his first nephrological experiences gained in the late sixties of the past century in the Institute of Patologia Medica in Perugia directed by Giovanni Gigli, and his subsequent experiences, which also included a period at Guy's Hospital in London. The interview also describes the important contributions that the school of Perugia produced in the field of nephrology and its main protagonists. This nephrological life story highlights: the role that internal medicine, with its multidisciplinary approach, had in the development of nephrology in its beginnings; the importance of cooperation with foreign institutions; the contributions that specialised research laboratories attached to renal units have given to the improvement of the diagnosis and to the understanding of the pathogenesis of nephropathies.

We propose a device for monitoring the number of people who are physically present inside indoor environments. The device performs local processing of infrared array sensor data detecting people’s direction, which allows monitoring users’ occupancy in any space of the building and also respects people privacy. The device implements a novel real-time pattern recognition algorithm for processing data sensed by a low-cost infrared (IR) array sensor. The computed information is transferred through a Z-Wave network. On-field evaluation of the algorithm has been conducted by placing the device on top of doorways in offices and laboratory rooms. To evaluate the performance of the algorithm in varying ambient temperatures, two groups of stress tests have been designed and performed. These tests established the detection limits linked to the difference between the average ambient temperature and perturbation. For an in-depth analysis of the accuracy of the algorithm, synthetic data have been generated considering temperature ranges typical of a residential environment, different human walking speeds (normal, brisk, running), and distance between the person and the sensor (1.5 m, 5 m, 7.5 m). The algorithm performed with high accuracy for routine human passage detection through a doorway, considering indoor ambient conditions of 21–30 °C.

Recessive mutations in DDHD2 cause SPG54, a complex hereditary spastic paraplegia (HSP) with less than forty patients reported worldwide. In this retrospective, multicenter study we describe eight additional SPG54 cases harboring homozygous or compound heterozygous DDHD2 variants. Finally, we reviewed literature data on SPG54, with the aim to better define the phenotype and the brain magnetic resonance imaging (MRI) pattern as well as genotype-phenotype correlations. SPG54 is typically characterized by early-onset (i.e., congenital or, more frequently, infantile) delay in motor and cognitive milestones, coupled or followed by appearance of spasticity. Cognitive impairment is absent in adult-onset cases. Spasticity progresses over time. Abnormal eye movement, found in about 50% of cases, is the feature most frequently associated with spasticity and developmental delay. Cerebellar ataxia is a prominent sign in several patients, including one adult of this study, suggesting to include SPG54 in the differential diagnosis of spastic-ataxia syndromes. Brain MRI shows thin corpus callosum and non-specific periventricular white matter lesions in about 90% and 70% of cases, respectively. Brain MR spectroscopy reveals abnormal lipid peak in 90% of investigated patients. Twenty-one pathogenic changes have been reported so far, many of which are nonsense or small deletion/duplication. Most mutations appear to be private, with only two mutations recurring in three (i.e., R287*) or more families (i.e., D660H). The identification of nine novel variants expands the molecular spectrum of DDHD2-related HSP and corroborates the notion of a quite homogeneous clinical and neuroradiological phenotype in spite of different genotypes.

Protocadherin 19 (PCDH19) mutations have been identified in epilepsy in females with mental retardation as well as patients with a "Dravet-like" phenotype. We aimed to elucidate the electroclinical phenotype associated with PCDH19 mutation, which is currently difficult to identify at onset leading to a delay in diagnosis. We retrospectively reviewed clinical and EEG data for 13 consecutive patients with PCDH19 mutations or deletions diagnosed at our centers from 2009 to 2011, and followed these patients into adolescence and adulthood. We identified a specific temporal sequence of electroclinical manifestations, identified as three main stages. During the first two years of life, previously healthy girls presented with clusters of afebrile focal seizures. Early seizures were recorded on video-EEG in 10/13 patients, and were focal (n=8) with temporo-occipital and frontal onset. Three patients with strictly stereotyped focal seizures underwent a pre-surgical work-up. Two patients started with generalized seizures, one presenting with early-onset atypical absences and the other generalized tonic-clonic seizures. During the course of the disease, from two to 10 years, seizures became fever-sensitive and continued to recur in clusters, although these were less frequent. Seizures were mainly described by eyewitnesses as generalized tonic-clonic, even though three of five seizures, recorded on EEG, showed a focal onset with fast bilateral spread. Atypical absences and fever-induced tonic-clonic seizures remained frequent in only one patient until the age of 16 years. No specific treatment or combination appeared to be more effective over another. Various degrees of cognitive or behavioural impairment were reported for all patients, but it was in the second decade that behavioural disturbances prevailed with hetero-aggressiveness and behaviour associated with frontal lobe abnormalities leading to psychosis in two. Early recognition of the above features should improve early diagnosis and long-term management of patients with epilepsy and PCDH19 mutations.

Background The Neurological involvement is the most common extra-renal complication of Shiga toxin-producing E. coli-hemolytic uremic syndrome (HUS) or typical HUS. On brain magnetic resonance examination, main neurological signs encompass acute lesions of the basal ganglia and the white matter, which could usually regress after Eculizumab infusion. In contrast, peripheral nervous system (PNS) manifestations in typical HUS are very rare and, when occurring, they require a careful management of neurological sequelae and an intensive multidisciplinary neuro-rehabilitation program. Case presentation Here, we present two pediatric cases of severe and complicated typical HUS with PNS manifestations who required therapeutic treatment and an intensive multidisciplinary neuro-rehabilitation program. In both cases, PNS manifestations were followed by the recovery from typical HUS-related severe central neurological damage and manifested mainly with marked bilateral motor deficit and hyporeflexia/areflexia in the lower limbs. The peripheral polyneuropathy was treated with immunosuppressive therapy (methylprednisolone boluses, i.v. immunoglobulins, plasma exchange), followed by a prolonged intensive neuro-rehabilitation program. After 8 months of rehabilitation, both patients gained complete functional recovery. Conclusions PNS manifestations during typical HUS are a rare event and potentially leading to severe disability. A timely clinical assessment is mandatory to set up a prompt therapeutic and rehabilitation program and to obtain a complete clinical and functional recovery.

The contribution of dysregulation of lipid signaling and metabolism to neurodegenerative diseases including Alzheimer’s and Parkinson’s is the focus of this special issue. Here, the matter of three reviews and one research article is summarized.

Background In heart failure, the exercise gas exchange Weber (A to D) and ventilatory classifications (VC‐1 to VC‐4) historically define disease severity and prognosis. However, their applications in the modern heart failure population of any left ventricular ejection fraction combined with hemodynamics are undefined. We aimed at revisiting and implementing these classifications by cardiopulmonary exercise testing imaging. Methods and Results 269 patients with heart failure with reduced (n=105), mid‐range (n=88) and preserved (n=76) ejection fraction underwent cardiopulmonary exercise testing imaging, primarily assessing the cardiac output (CO), mitral regurgitation, and mean pulmonary arterial pressure (mPAP)/CO slope. Within both classes, a progressively lower exercise CO, higher mPAP/CO slopes, and mitral regurgitation ( P P P =0.017) were independently associated with outcome. The best stratification was observed when combining Weber (A/B or C/D) with severe ventilation inefficiency (VC‐4) (HR, 2.7; 95% CI, 1.6–4.8; P P P Conclusions In the contemporary heart failure population, the Weber and ventilatory classifications maintain their prognostic ability, especially when combined. Exercise CO and mPAP/CO slope are the best predictors of peak oxygen consumption and ventilation to carbon dioxide production slope classifications representing the main targets of interventions to impact functional class and, likely, event rate.

The author singled out the first decade of the 20th century as the time in which the renewal of academic medicine in post-unification Italy was concluded, while the changes that would be induced by the following war had not yet started. A bibliographic research relating to this period was undertaken with the aim of investigating the number and the quality of the studies on kidneys published by Italian scientists. A total of 176 publications of Italian scientists dealing with kidney diseases or physiology was retrieved, 10.8% of which was published on foreign journals. The analysis of the topics treated shows that they were up to date and comparable with the contemporary studies across Europe. Moreover, the issues raised remained of interest throughout the following decades up to our day. Top Italian researchers were fairly cited, especially if they published on international journals. While at the time the state of other organs was mainly assessed by examining physical signs and symptoms, kidney studies required laboratory facilities. This limitation meant that kidney scholars usually belonged to well established medical faculties. From these schools, a few figures stood out among the others for the importance of their studies, both physiological and clinical in nature. The same figures also gave birth to the major Italian schools of internal medicine from which, half a century later, originated the Italian Society of Nephrology. The findings of this research support the conclusion that the basis of modern nephrology can be traced back to that decade.

Background The best available treatment against carbapenemase-producing Enterobacteriaceae (CPE) is unknown. The objective of this study was to investigate the effect of appropriate therapy and of appropriate combination therapy on mortality of patients with bloodstream infections (BSIs) due to CPE. Methods In this retrospective cohort study, we included patients with clinically significant monomicrobial BSIs due to CPE from the INCREMENT cohort, recruited from 26 tertiary hospitals in ten countries. Exclusion criteria were missing key data, death sooner than 24 h after the index date, therapy with an active antibiotic for at least 2 days when blood cultures were taken, and subsequent episodes in the same patient. We compared 30 day all-cause mortality between patients receiving appropriate (including an active drug against the blood isolate and started in the first 5 days after infection) or inappropriate therapy, and for patients receiving appropriate therapy, between those receiving active monotherapy (only one active drug) or combination therapy (more than one). We used a propensity score for receiving combination therapy and a validated mortality score (INCREMENT-CPE mortality score) to control for confounders in Cox regression analyses. We stratified analyses of combination therapy according to INCREMENT-CPE mortality score (0–7 [low mortality score] vs 8–15 [high mortality score]). INCREMENT is registered with ClinicalTrials.gov, number NCT01764490. Findings Between Jan 1, 2004, and Dec 31, 2013, 480 patients with BSIs due to CPE were enrolled in the INCREMENT cohort, of whom we included 437 (91%) in this study. 343 (78%) patients received appropriate therapy compared with 94 (22%) who received inappropriate therapy. The most frequent organism was Klebsiella pneumoniae (375 [86%] of 437; 291 [85%] of 343 patients receiving appropriate therapy vs 84 [89%] of 94 receiving inappropriate therapy) and the most frequent carbapenemase was K pneumoniae carbapenemase (329 [75%]; 253 [74%] vs 76 [81%]). Appropriate therapy was associated with lower mortality than was inappropriate therapy (132 [38·5%] of 343 patients died vs 57 [60·6%] of 94; absolute difference 22·1% [95% CI 11·0–33·3]; adjusted hazard ratio [HR] 0·45 [95% CI 0·33–0·62]; p

Fine needle cytology (FNC) is a crucial procedure in the preoperative diagnosis of thyroid tumors. Papillary thyroid carcinoma (PTC), in its classic variant (cPTC), is the most common malignant neoplasm of the thyroid. Several histological variants of PTC have been described, each one with its own characteristics and prognosis. The ability of FNC to identify the variants represents a challenge even for a skilled pathologist. The aim of this study was to evaluate the diagnostic cytological accuracy of FNC in PTC and to look for specific features that could predict the different variants. This was a single center prospective study on 128 patients who received a diagnosis of PTC on FNC. The smears were blindly reviewed by two cytopathologists to create a frequency score (0, 1, 2, 3) of the features for each variant. The cytological parameters were divided into three groups: architectural, nucleo-cytoplasmic, and background features. Univariate analysis was performed by chi-square test with Yates correction and Fisher exact test as appropriate. Multiple regression analysis was performed among the variables correlated at the linear correlation. The correlation study between cytology and histology showed an accuracy of FNC in classic, follicular, and oncocytic PTC variants of 63.5, 87.5, and 87% respectively. Familiarity with cytological features may allow an early diagnosis of a given PTC variant on FNC samples. This is fundamental in a preoperative evaluation for the best surgical approach and subsequent treatment.

Although studies suggest decreased incident hepatocellular carcinoma (HCC) after treatment with direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection, data are conflicting regarding risk and aggressiveness of recurrence in patients who have a history of treated HCC. This review analyses data available in literature in order to elucidate the impact of DAAs on the risk of HCC recurrence after successful treatment of the tumor. Overall 24 papers were identified. The available data cannot be considered definitive, but the initial alarmist data indicating an increased risk of recurrence have not been confirmed by most subsequent studies. The suggested aggressive pattern (rapid growth and vascular invasion) of tumor recurrence after DAAs still remains to be confirmed. Several limitations of the available studies were highlighted, and should drive future researches. The time-to-recurrence should be computed since the last HCC treatment and results stratified for cirrhosis and sustained viral response. Any comparison with historical series is of limited interest because of a number of biases affecting these studies and differences between enrolled patients. Prospective intention-to-treat analyses will be probably the best contribution to drive clinical practice, provided that a randomized trial can be difficult to design.

With the introduction of direct-acting antiviral agents (DAA), the rate of sustained virological response (SVR) in the treatment of hepatitis C virus (HCV) has radically improved to over 95%. Robust scientific evidence supports a beneficial role of SVR after interferon therapy in the progression of cirrhosis, resulting in a decreased incidence of hepatocellular carcinoma (HCC). However, a debate on the impact of DAAs on the development of HCC is ongoing. This review aimed to analyse the scientific literature regarding the risk of HCC in terms of its recurrence and occurrence after the use of DAAs to eradicate HCV infection. Among 11 studies examining HCC occurrence, the de novo incidence rate ranged from 0 to 7.4% (maximum follow-up: 18 mo). Among 18 studies regarding HCC recurrence, the rate ranged from 0 to 54.4% (maximum "not well-defined" followup: 32 mo). This review highlights the major difficulties in interpreting data and reconciling the results of the included studies. These difficulties include heterogeneous cohorts, potential misclassifications of HCC prior to DAA therapy, the absence of an adequate control group, short follow-up times and different kinds of follow-up. Moreover, no clinical feature-based scoring system accounts for the molecular characteristics and pathobiology of the tumours. Nonetheless, this review does not suggest that there is a higher rate of de novo HCC occurrence or recurrence after DAA therapy in patients with previous HCV infection. © 2018 The Author(s).

Snail is a target of USP1 that links platinum response to metastasis in ovarian cancer., Resistance to platinum-based chemotherapy is a common event in patients with cancer, generally associated with tumor dissemination and metastasis. Whether platinum treatment per se activates molecular pathways linked to tumor spreading is not known. Here, we report that the ubiquitin-specific protease 1 (USP1) mediates ovarian cancer cell resistance to platinum, by regulating the stability of Snail, which, in turn, promotes tumor dissemination. At the molecular level, we observed that upon platinum treatment, USP1 is phosphorylated by ATM and ATR and binds to Snail. Then, USP1 de-ubiquitinates and stabilizes Snail expression, conferring resistance to platinum, increased stem cell–like features, and metastatic ability. Consistently, knockout or pharmacological inhibition of USP1 increased platinum sensitivity and decreased metastatic dissemination in a Snail-dependent manner. Our findings identify Snail as a USP1 target and open the way to a novel strategy to overcome platinum resistance and more successfully treat patients with ovarian cancer.

Background Cervical cancer cells often express Epidermal Growth Factor Receptor (EGFR). Cetuximab (CET), an anti-EGFR antibody, can be safely combined with carboplatin (C) and paclitaxel (P), a standard treatment for advanced/recurrent cervical cancer (ARCC) patients. Patients and methods ARCC patients, ECOG PS ≤ 1, were randomized to CP for 6 cycles with or without CET (400 mg/m2 one week before starting CP, then 250 mg/m2 weekly) until disease progression or unacceptable toxicity. Event-free survival (EFS) was the primary endpoint. With a 4.5 months expected median EFS and a 6.4 months predicted EFS (HR 0.70), 0.20 one-tailed α and 80% power, 89 events were required for the final intent-to-treat analysis. Results 108 patients were assigned to CP (n = 53) or CP-CET (n = 55). Median age was 50, 69% were PS0, 76% had recurrent disease, 91% had distant metastasis and 57% had received previous chemotherapy. After a median follow-up of 23 months, 102 patients had an event, 97 progressed and 61 died. Median EFS was 4.7 and 6.0 months (one-tail P = 0.43), median PFS was 5.2 and 7.6 months (one-tail P = 0.20) and median OS was 17.7 and 17 months (one-tail P = 0.27), with CP and CP-CET, respectively. There was no difference in the occurrence of severe adverse events, except for skin toxicity. Biomarker analysis, in a small subgroup of patients, suggests that PIK3CA mutation might be predictive of CET resistance. Conclusion CP-CET was not more active than CP alone in unselected ARCC patients.

Skin and soft tissue infections (SSTIs) represent a wide range of clinical conditions characterized by a considerable variety of clinical presentations and severity. Their aetiology can also vary, with numerous possible causative pathogens. While other authors previously published analyses on several types of SSTI and on restricted types of patients, we conducted a large nationwide surveillance programme on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients. Twenty-five Infectious Diseases (ID) Centres throughout Italy collected prospectively data concerning both the clinical and microbiological diagnosis of patients affected by SSTIs via an electronic case report form. All the cases included in our database, independently from their severity, have been managed by ID specialists joining the study while SSTIs from other wards/clinics have been excluded from this analysis. Here, we report the preliminary results of our study, referring to a 12-month period (October 2016-September 2017). During this period, the study population included 254 adult patients and a total of 291 SSTI diagnoses were posed, with 36 patients presenting more than one SSTIs. The type of infection diagnosed, the aetiological micro-organisms involved and some notes on their antimicrobial susceptibilities were collected and are reported herein. The enrichment of our registry is ongoing, but these preliminary results suggest that further analysis could soon provide useful information to better understand the national epidemiologic data and the current clinical management of SSTIs in Italy.

Urinary tract infections (UTIs) are among the most common infections in all age groups. Fast and accurate diagnosis is essential to ensure a timely and effective therapy. Alongside with reference culture-based methods, several point-of-care tests (POCTs) for early detection of UTIs have been developed, but they have not been significantly implemented in current clinical practice. The Micro Biological Survey (MBS) POCT is a simple test developed by MBS Diagnostics Ltd. (London, UK) for the detection and management of UTIs. The present study has been undertaken to investigate the potentials and limits of the MBS POCT. A total of 349 patients were enrolled in two open-label, monocentric, non-interventional clinical trials in collaboration with an Emergency Medicine department and the outpatient clinic of two hospitals in Rome. Results of urine analysis using the MBS POCT were compared with those of the routine culture-based tests for UTI diagnosis performed by the hospital laboratory. The MBS POCT provided fast results revealing high bacterial count UTIs (≥ 105 CFU/ml) with 97% accuracy, 92% sensitivity, 100% specificity, 99% PPV, and 96% NPV within a 5-h analytical time threshold.

Lipidomics suffers from the lack of fast and reproducible tools to obtain both structural information on intact phospholipids (PL) and fatty acyl chain composition. Hydrophilic interaction liquid chromatography with electrospray ionization coupled to an orbital-trap Fourier-transform analyzer operating using all ion fragmentation mode (HILIC-ESI-FTMS-AIF MS) is seemingly a valuable resource in this respect. Here, accurate m/z values, HILIC retention times and AIF MS scan data were combined for PL assignment in standard mixtures or real lipid extracts. AIF scans in both positive and negative ESI mode, achieved using collisional induced dissociation for fragmentation, were applied to identify both the head-group of each PL class and the fatty acyl chains, respectively. An advantage of the AIF approach was the concurrent collection of tandem MS-like data, enabling the identification of linked fatty acyl chains of precursor phospholipids through the corresponding carboxylate anions. To illustrate the ability of AIF in the field of lipidomics, two different types of real samples, i.e., the lipid extracts obtained from human plasma and dermal fibroblasts, were examined. Using AIF scans, a total of 253 intact lipid species and 18 fatty acids across 4 lipid classes were recognized in plasma samples, while FA C20:3 was confirmed as the fatty acyl chain belonging to phosphatidylinositol, PI 38:3, which was found to be down-regulated in fibroblast samples of Parkinson&rsquo, s disease patients.

Background School violence and bullying are a pandemic issue. The academic literature underlined the need to investigate social-contextual risk factors. The United Nations called for more comprehensive and disaggregated data to inform prevention strategies. Objective The present study comprises a set of secondary analyses on Italian data from the International Civic and Citizenship Study 2016. We adopted an innovative ‘bottom-up’ approach to identify the level of disaggregation for national data. The researchers focused on community, social, and economic risk indicators at school-level, and investigated whether it was possible to aggregate schools in different classes, depending on their risk profile. Participants and settings Analyses were implemented on a nationally representative sample of 170 Principals of lower secondary schools, 2,527 teachers and 3,766 students at grade 8. Methods and analyses A Latent Class Analyses was conducted on risk indicators and four classes of risk were identified: No Risk, Community Risk, Socio-economic Risk, Multi-Risk (entropy = .786). No significant differences were found across classes in relation to urban/rural location, school size, and geographical macro-partition. On the contrary, significant differences emerged when considering teachers’ perception of bullying, social problem, and students’ behavior at school. Furthermore significant differences were found for the quality of relationship with teachers as reported by students. Conclusions Results a) suggested a potential gradient of increasing risk moving across the classes; b) provided a contribution to address the gap in the investigation of contextual factors and bullying; c) offered a new lens to tailor interventions to prevent school violence and bullying.

Background Management of spinal muscular atrophy (SMA) has progressed enormously and reached unprecedented levels with nusinersen gene therapy. We are finally able to counter the progression of this devastating genetic disease, contributing to the definition of new trajectories in its natural history and the identification of new SMA phenotypes post-gene therapy. The aim of this paper was to use the The International Classification of Functioning, Disability and Health-Children and Youth as a framework for the management of spinal muscular atrophy in the era of gene therapy: a proof-of-concept study (ICF-CY) as a comprehensive documentation tool to better understand and improve care provided to a child with SMA and to illustrate its use in a multidisciplinary perspective with a proof-of-concept study. Case report An SMA child under gene therapy receiving a rehabilitation program. Clinical and functional outcome measures assessed at all levels of the ICF-CY, including impairment by Hammersmith Infant Neurological Examination, activity by Hammersmith Functional Motor Scale and Functional Independence Measure for Children, and participation by Pediatric Quality of Life Inventory™ - PedsQL™ and Neuromuscular Module™ as well as by parent report. Treatment outcomes were assessed at two main time points: at T0: prior to administration of nusinersen, and T1: immediately before the first administration of maintenance doses, 6 months after the first administration of nusinersen. A significant clinical improvement was seen on all domains between T0 and T1. The patient improved especially in motor skills and motor disability severity. The HRQOL showed a substantial improvement, too. ICF-CY codes were used to document change in body functions or structures, performance of activities or participation in social roles both in terms of gradient and hierarchy of change. This proof-of-concept study is the first attempt to explore SMA in a comprehensive manner from the perspective of the ICF-CY using a selected set of codes. These codes define essential child dimensions that can make up an ICF-CY core set, as identified by a trained multidisciplinary team, to guide assessment, treatment and rehabilitation. Clinical rehabilitation impact Although limited to a single patient, this study makes nonetheless a strong point: we suggest using the ICF-CY as an essential tool in SMA management at a time when gene therapy with nusinersen is changing the phenotypes of activity and functioning in these children.

Background and purpose The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2. Methods Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group. Results In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection. Conclusions Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

INTRODUCTION: Residents in facilities such as nursing homes (NHs) are particularly vulnerable to Coronavirus disease 2019 (COVID-19). A national survey was carried out to collect information on the spreading and impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in nursing homes, and on how suspected and/or confirmed cases were managed. We carried out a survey between 25 March 2020 and 5 May 2020. MATERIALS AND METHODS: All Italian nursing homes either public or providing services both privately and within the NHS were included in the study. An on-line questionnaire was sent to 3292 nursing homes across all Italian regions. Nursing homes were also contacted by telephone to provide assistance in completing the questionnaire. RESULTS: A total of 1356 nursing homes voluntarily participated to the survey, hosting a total of 100,806 residents. Overall, 9154 residents died due to any cause from February 1 to the time when the questionnaire was completed (from March 25 to May 5). Of these, 7.4% had COVID-19 and 33.8% had flu-like symptoms, corresponding to a cumulative incidence of 0.7 and 3.1, respectively. Lack of personnel, difficulty in transferring patients to hospital or other facility, isolating residents with COVID-19, number of beds and geographical area were the main factor positively associated to the presence of COVID-19 in nursing homes. DISCUSSION: This survey showed the dissemination and impact of SARS-CoV-2 infection in Italian nursing homes and on how older and potentially chronically ill people residing in these long-term care facilities were managed.

Methods: Sixty-one human NETs were included into the study. CXCR4/CXCL12/CXCR7 axis and mTOR pathway were assessed by qRT-PCR and immunohistochemistry (IHC). The effect of mTOR inhibitor, RAD001, was evaluated on CXCR4 pathway through proliferation and p-Erk and p-AKT induction. Results: CXCR4/CXCL12/CXCR7 axis and p-mTOR were found to be active and correlated with grading, Ki67 index and tumor stage. mTOR pathway activation significantly correlated with poor prognosis. In human NET cells, CXCL12 induced mTOR signalling while AMD3100 (CXCR4-antagonist) impaired it. The mTOR-antagonist, RAD001, impaired the CXCL12-dependent induction of CXCR4 downstream effectors. Combination of AMD3100 and RAD001 potentiate cell growth inhibition. Conclusions: CXCR4/CXCL12/CXCR7 axis is active in NETs and signals on mTOR. CXCR4 might be considered a prognostic factor in NETs. Combined treatment with AMD3100 and RAD001 may provide clinical benefits in NET patients with drug-resistant.

Objective Low-grade endometrial stromal sarcoma (LG-ESS) is a rare malignancy, often occurring before menopause. There is no consensus regarding its optimal management. Total hysterectomy and bilateral salpingo-oophorectomy precludes future fertility and may thus be undesirable by women wishing to maintain their reproductive potential. However, experience of fertility-sparing management in LG-ESS is very limited. In this paper, the disease outcome is presented in six young women with LG-ESS conservatively treated by combined hysteroscopic resection and hormonal therapy. Study design From October 2009 to February 2013, at the Gynecologic Oncology Department of the National Cancer Institute of Naples, six women, with early-stage LG-ESS aged 18–40 years who desired childbearing and/or retaining their fertility, were enrolled into a pilot study of fertility-sparing management. Diagnosis of LG-ESS was made on specimens from hysteroscopic resection performed on a presumed benign lesion. All patients were planned to be treated with adjuvant megestrol acetate for two years. Hormonal therapy was started within 6 weeks from the hysteroscopic resection, with orally megestrol acetate at 40 mg daily, increasing gradually according to patient's tolerance to the recommended total dose of 160 mg daily. Results All patients were submitted to hysteroscopic resection in a one-step procedure. Five patients started megestrol acetate within 6 weeks from the hysteroscopic resection (one patient did not start hormonal therapy because of early pregnancy after the hysteroscopic resection). Hormonal therapy was well tolerated; one patient stopped megestrol acetate after 12 months because of self-supporting strong desire to conceive; the other four patients regularly completed the hormonal therapy. To date, all patients show no evidence of disease. Conclusions Although fertility-sparing management is not the current standard of care for young women with early-stage LG-ESS, our preliminary data are promising. Larger series with a longer follow-up are needed to further assess safety and efficacy of combined hysteroscopic resection and hormonal therapy.

Angiosarcoma and anaplastic carcinoma are the most lethal neoplasms of the thyroid worldwide and share some similarities, which have led to a longstanding controversy on their etiopathological relationship. Thyroid angiosarcomas are characterized by vessel formation and an immunophenotype common to endothelial cells, while anaplastic carcinomas are partially or wholly composed of mesenchymal-like cells that have lost the morphologic and functional features of normal thyroid follicular cells. To investigate whether angiosarcomas represent the endothelial extreme of the differentiation spectrum of carcinomas or they are bona fide vascular neoplasms, we studied the clinico-morphologic and genetic characteristics of a series of 10 angiosarcomas and 22 anaplastic carcinomas. Immunohistochemically, among the endothelial markers, CD31 and ERG were the most consistently expressed in angiosarcomas. Among the markers of thyroid origin, PAX8 was the most reliable in anaplastic carcinomas, while TTF-1 reactivity was found in only 5% of anaplastic carcinomas and thyroglobulin was always negative. Pankeratin reacted with most angiosarcomas and anaplastic carcinomas and is therefore not useful in the differential diagnosis. Interestingly a mutated pattern of p53 immunostaining prompted a diagnosis of anaplastic carcinoma. To compare the genetic profile, we used the NGS approach to sequence hotspot regions within a panel of 57 genes. As a result, only a few mutations were found in angiosarcomas and all of them were single events (no TP53 or TERT mutation). On the other hand, anaplastic carcinomas were characterized by a higher number of mutations, and TP53 and TERT promoter mutations were the most frequent genetic alterations. The lack in angiosarcomas of the common mutations identified in anaplastic carcinomas supports a different genetic origin and strongly suggests that, in spite of a shared sarcomatous morphology and a similar clinical aggressiveness, angiosarcomas and anaplastic carcinomas rely on a completely different set of genetic alterations during their evolution.

In patients with recurrent ovarian cancer, the choice of second-line therapy is complex. Several factors have to be considered, such as platinum-free interval (PFI), residual toxicity from the previous treatments, BRCA1/2 gene mutation status. Trebectedin is a minor groove DNA binder derived from a marine organism that has shown efficacy in different settings in ovarian cancer therapy. It has been approved in the treatment of partially platinum sensitive (PPS) (PFI between 6 and 12 months) relapsed ovarian cancer according to the statistically significant progression-free survival (7.3 versus 5.8 months) and overall survival (22.2 versus 18.9 months) benefit compared with single-agent pegylated liposomal doxorubicin (PLD) in the OVA 301 phase III trial. This drug has been shown to prolong the time to first subsequent treatment and improve the efficacy of further platinum-based chemotherapy. The role of trabectedin/PLD followed by platinum combination compared with the reverse sequence in PPS is actually in evaluation in the INOVATYON phase III study, which will clarify the best sequence to be adopted in this setting. Trabectedin has been shown to be active in patient carriers of BRCA mutations, probably for its mechanism of action directly affecting DNA and it is actually tested as a single agent in some phase III trials in BRCA mutated and BRCAness ovarian cancer patients. Trabectedin is also active on the immune system. There is, therefore, the rational for new trials of a combination with immune checkpoint inhibitors.
