Simple Summary: This study collected data from patients with cutaneous melanoma with mutation in the B-RAF gene who were treated with the combination of dabrafenib and trametinib in 34 Italian hospitals in every-day clinical practice. The aim was to understand how these drugs modify the progression pattern of the tumor in a heterogeneous population of patients who had either a limited (104 patients) or a bulky disease (97 patients). The results showed that fewer patients had lesions at the skin and more patients had lesions in other sites rather than the skin and lymph nodes when the disease progressed compared to baseline, and the proportion of patients with at least three involved organs at the progression increased in both cohorts. The survival and the time without progression were similar to previously published data and no new adverse reactions were reported. Therefore, dabrafenib and trametinib demonstrated to be effective and safe in heterogenous patients. In patients with B-RAF-mutated cutaneous melanoma, targeted therapies are the treatment of choice to achieve a rapid response. In this multicentric, prospective, observational study, patients with B-RAF-mutated cutaneous melanoma who were treated with dabrafenib and trametinib were categorized in two cohorts (cohort A: limited disease (n = 104) and cohort B: bulky disease (n = 97)) according to lactate dehydrogenase levels. The primary endpoint was the progression pattern; the secondary endpoints were overall survival (OS), progression-free survival (PFS), and safety data. From baseline to time of progression, there was a progression from nodal to other sites of disease in cohort A and from skin and nodal to other sites in cohort B. In both the cohorts, the number of involved organs and metastases at each location decreased. The median OS was 32.4 months (95% CI: 20.1 months (not estimable)) for cohort A, and 10.5 months (95% CI: 8.3–14.4 months) for cohort B; median PFS was 12.4 months (95% CI: 10.9–17.0 months) for cohort A, and 8.1 months (95% CI: 6.3–9.4 months) for cohort B. No new safety signals were reported. This study describes the patterns of first-line treatment progression with dabrafenib and trametinib in Italian clinical practice. The effectiveness and safety data were consistent with previous trials and extended to a real-world heterogeneous population. [ABSTRACT FROM AUTHOR]

Background: Previously, findings from CheckMate 238, a double-blind, phase 3 adjuvant trial in patients with resected stage IIIB-C or stage IV melanoma, showed significant improvements in recurrence-free survival and distant metastasis-free survival with nivolumab versus ipilimumab. This report provides updated 4-year efficacy, initial overall survival, and late-emergent safety results.Methods: This multicentre, double-blind, randomised, controlled, phase 3 trial was done in 130 academic centres, community hospitals, and cancer centres across 25 countries. Patients aged 15 years or older with resected stage IIIB-C or IV melanoma and an Eastern Cooperative Oncology Group performance status of 0 or 1 were randomly assigned (1:1) to receive nivolumab or ipilimumab via an interactive voice response system and stratified according to disease stage and baseline PD-L1 status of tumour cells. Patients received intravenous nivolumab 3 mg/kg every 2 weeks or intravenous ipilimumab 10 mg/kg every 3 weeks for four doses, and then every 12 weeks until 1 year of treatment, disease recurrence, unacceptable toxicity, or withdrawal of consent. The primary endpoint was recurrence-free survival by investigator assessment, and overall survival was a key secondary endpoint. Efficacy analyses were done in the intention-to-treat population (all randomly assigned patients). All patients who received at least one dose of study treatment were included in the safety analysis. The results presented in this report reflect the 4-year update of the ongoing study with a database lock date of Jan 30, 2020. This study is registered with ClinicalTrials.gov, NCT02388906.Findings: Between March 30 and Nov 30, 2015, 906 patients were assigned to nivolumab (n=453) or ipilimumab (n=453). Median follow-up was 51·1 months (IQR 41·6-52·7) with nivolumab and 50·9 months (36·2-52·3) with ipilimumab; 4-year recurrence-free survival was 51·7% (95% CI 46·8-56·3) in the nivolumab group and 41·2% (36·4-45·9) in the ipilimumab group (hazard ratio [HR] 0·71 [95% CI 0·60-0·86]; p=0·0003). With 211 (100 [22%] of 453 patients in the nivolumab group and 111 [25%] of 453 patients in the ipilimumab group) of 302 anticipated deaths observed (about 73% of the originally planned 88% power needed for significance), 4-year overall survival was 77·9% (95% CI 73·7-81·5) with nivolumab and 76·6% (72·2-80·3) with ipilimumab (HR 0·87 [95% CI 0·66-1·14]; p=0·31). Late-emergent grade 3-4 treatment-related adverse events were reported in three (1%) of 452 and seven (2%) of 453 patients. The most common late-emergent treatment-related grade 3 or 4 adverse events reported were diarrhoea, diabetic ketoacidosis, and pneumonitis (one patient each) in the nivolumab group, and colitis (two patients) in the ipilimumab group. Two previously reported treatment-related deaths in the ipilimumab group were attributed to study drug toxicity (marrow aplasia in one patient and colitis in one patient); no further treatment-related deaths were reported.Interpretation: At a minimum of 4 years' follow-up, nivolumab demonstrated sustained recurrence-free survival benefit versus ipilimumab in resected stage IIIB-C or IV melanoma indicating a long-term treatment benefit with nivolumab. With fewer deaths than anticipated, overall survival was similar in both groups. Nivolumab remains an efficacious adjuvant treatment for patients with resected high-risk melanoma, with a safety profile that is more tolerable than that of ipilimumab.Funding: Bristol Myers Squibb and Ono Pharmaceutical.

Background: A phase 2 trial suggested increased overall survival and increased incidence of treatment-related grade 3-4 adverse events with ipilimumab 10 mg/kg compared with ipilimumab 3 mg/kg in patients with advanced melanoma. We report a phase 3 trial comparing the benefit-risk profile of ipilimumab 10 mg/kg versus 3 mg/kg.Methods: This randomised, double-blind, multicentre, phase 3 trial was done in 87 centres in 21 countries worldwide. Patients with untreated or previously treated unresectable stage III or IV melanoma, without previous treatment with BRAF inhibitors or immune checkpoint inhibitors, were randomly assigned (1:1) with an interactive voice response system by the permuted block method using block size 4 to ipilimumab 10 mg/kg or 3 mg/kg, administered by intravenous infusion for 90 min every 3 weeks for four doses. Patients were stratified by metastasis stage, previous treatment for metastatic melanoma, and Eastern Cooperative Oncology Group performance status. The patients, investigators, and site staff were masked to treatment assignment. The primary endpoint was overall survival in the intention-to-treat population and safety was assessed in all patients who received at least one dose of study treatment. This study is completed and was registered with ClinicalTrials.gov, number NCT01515189.Findings: Between Feb 29, and July 9, 2012, 727 patients were enrolled and randomly assigned to ipilimumab 10 mg/kg (365 patients; 364 treated) or ipilimumab 3 mg/kg (362 patients; all treated). Median follow-up was 14·5 months (IQR 4·6-42·3) for the ipilimumab 10 mg/kg group and 11·2 months (4·9-29·4) for the ipilimumab 3 mg/kg group. Median overall survival was 15·7 months (95% CI 11·6-17·8) for ipilimumab 10 mg/kg compared with 11·5 months (9·9-13·3) for ipilimumab 3 mg/kg (hazard ratio 0·84, 95% CI 0·70-0·99; p=0·04). The most common grade 3-4 treatment-related adverse events were diarrhoea (37 [10%] of 364 patients in the 10 mg/kg group vs 21 [6%] of 362 patients in the 3 mg/kg group), colitis (19 [5%] vs nine [2%]), increased alanine aminotransferase (12 [3%] vs two [1%]), and hypophysitis (ten [3%] vs seven [2%]). Treatment-related serious adverse events were reported in 133 (37%) patients in the 10 mg/kg group and 66 (18%) patients in the 3 mg/kg group; four (1%) versus two (<1%) patients died from treatment-related adverse events.Interpretation: In patients with advanced melanoma, ipilimumab 10 mg/kg resulted in significantly longer overall survival than did ipilimumab 3 mg/kg, but with increased treatment-related adverse events. Although the treatment landscape for advanced melanoma has changed since this study was initiated, the clinical use of ipilimumab in refractory patients with unmet medical needs could warrant further assessment.Funding: Bristol-Myers Squibb.

Background: This case report describes a spontaneous tumor lysis syndrome due to a rare solid tumor.Case Presentation: A 65-year-old white woman had tumor lysis syndrome, which represent a dangerous oncological emergency. This syndrome occurs usually with a hematological tumor, but in this case our patient had a solid tumor, which was a rare extraskeletal osteosarcoma, localized in her pelvic region. She also had lung metastases and bilateral hydronephrosis. After spontaneous tumor lysis syndrome, she had acute renal insufficiency, which was treated with hemodialysis and successively with rasburicase, Kayexalate (sodium polystyrene sulfonate), and febuxostat.Conclusion: Tumor lysis syndrome represents an oncological emergency, which must be suspected and treated as soon as possible.

Background: The orally available BRAF kinase inhibitor vemurafenib, compared with dacarbazine, shows improved response rates, progression-free survival (PFS), and overall survival in patients with metastatic melanoma that has a BRAF(V600) mutation. We assessed vemurafenib in patients with advanced metastatic melanoma with BRAF(V600) mutations who had few treatment options.Methods: In an open-label, multicentre study, patients with untreated or previously treated melanoma and a BRAF(V600) mutation received oral vemurafenib 960 mg twice a day. The primary endpoint was safety. All analyses were done on the safety population, which included all patients who received at least one dose of vemurafenib. This report is the third interim analysis of this study. This study is registered with ClinicalTrials.gov, number NCT01307397.Findings: Between March 1, 2011, and Jan 31, 2013, 3226 patients were enrolled in 44 countries. 3222 patients received at least one dose of vemurafenib (safety population). At data cutoff, 868 (27%) patients were on study treatment and 2354 (73%) had withdrawn, mainly because of disease progression. Common adverse events of all grades included rash (1592 [49%]), arthralgia (1259 [39%]), fatigue (1093 [34%]), photosensitivity reaction (994 [31%]), alopecia (826 [26%]), and nausea (628 [19%]). 1480 (46%) patients reported grade 3 or 4 adverse events, including cutaneous squamous cell carcinoma (389 [12%]), rash (155 [5%]), liver function abnormalities (165 [5%]), arthralgia (106 [3%]), and fatigue (93 [3%]). Grade 3 and 4 adverse events were reported more frequently in patients aged 75 years and older (n=257; 152 [59%, 95% CI 53-65] and ten [4%, 2-7], respectively) than in those younger than 75 years (n=2965; 1286 [43%, 42-45] and 82 [3%, 2-3], respectively).Interpretation: Vemurafenib safety in this diverse population of patients with BRAF(V600) mutated metastatic melanoma, who are more representative of routine clinical practice, was consistent with the safety profile shown in the pivotal trials of this drug.Funding: F Hoffmann-La Roche.

Abstract: Background: Mucosal melanoma is an extremely rare and aggressive malignancy that often remains undetected until it reaches an advanced stage, when effective treatment options are limited. The activity and safety of ipilimumab were assessed in an Expanded Access Programme (EAP) that included patients with metastatic, mucosal melanoma. Methods: Ipilimumab was available upon physician request for patients aged ⩾16years with stage III (unresectable) or IV skin, ocular or mucosal melanoma, who had failed or did not tolerate previous treatments and had no other therapeutic option available. Patients received ipilimumab 3mg/kg every 3weeks for four doses. Patients with stable disease or an objective response to ipilimumab were eligible for retreatment upon disease progression. Tumour assessments were conducted at baseline and week 12 using immune-related response criteria. Patients were monitored for adverse events (AEs), including immune-related AEs, within 3 to 4days of each scheduled visit. Results: Of 855 patients participating in the EAP in Italy, 71 (8%) had metastatic, mucosal melanoma. With a median follow-up of 21.8months, the response rate was 12% and the immune-related disease control rate was 36%. Median progression-free survival and overall survival were 4.3 and 6.4months, respectively. In total, 34% of patients reported treatment-related AEs of any grade, which were grade 3 or 4 in 9% of patients. AEs were generally manageable as per protocol-specific guidelines. Conclusion/interpretation: Ipilimumab may be a feasible treatment option in pretreated patients with metastatic mucosal melanoma, and warrants further investigation in prospective clinical trials.

Nivolumab was approved as adjuvant therapy for melanoma based on data from CheckMate 238, which enrolled patients per American Joint Committee on Cancer version 7 (AJCC-7) criteria. Here, we analyse long-term outcomes per AJCC-8 staging criteria compared with AJCC-7 results to inform clinical decisions for patients diagnosed per AJCC-8. In a double-blind, phase 3 trial (NCT02388906), patients aged ≥15 years with resected, histologically confirmed AJCC-7 stage IIIB, IIIC, or IV melanoma were randomised to receive nivolumab 3 mg/kg every 2 weeks or ipilimumab 10 mg/kg every 3 weeks for 4 doses and then every 12 weeks, both intravenously ≤1 year. Recurrence-free survival (RFS) and distant metastasis-free survival (DMFS) were assessed in patients with stage III disease, per AJCC-7 and AJCC-8. Per AJCC-7 staging, 42.4% and 57.3% of patients were in substage IIIB and IIIC, respectively; per AJCC-8, 1.1%, 30.4%, 62.8%, and 5.0% were in IIIA, IIIB, IIIC, and IIID. After 4 years' minimum follow-up, the AJCC-7 superior efficacy of nivolumab over ipilimumab in patients with resected stage III melanoma was preserved per AJCC-8 analysis. No statistically significant difference in RFS between stage III substage hazard ratios was observed per AJCC-7 or -8 staging criteria (interaction test: AJCC-7, P = 0.8115; AJCC-8, P = 0.1051; P = 0.8392 ((AJCC-7) and P = 0.8678 (AJCC-8) for DMFS). CheckMate 238 4-year RFS and DMFS outcomes are consistent per AJCC-7 and AJCC-8 staging criteria. Outcome benefits can therefore be translated for patients diagnosed per AJCC-8. • Nivolumab superior to ipilimumab per American Joint Committee on Cancer version 7 (AJCC-7) was preserved when analysed per AJCC-8. • Longer recurrence-free survival and distant metastasis-free survival with nivolumab across staging criteria and substages. • Adjuvant nivolumab benefit and risk information for patients diagnosed per AJCC-8.

Fibromyalgia is a debilitating condition marked by persistent pain and reduced functionality. Various therapeutic methods have been suggested to alleviate symptoms in individuals with fibromyalgia, yet the impact of diverse rehabilitation strategies remains unclear. This systematic review and meta-analysis aimed at assessing the efficacy of rehabilitation interventions in improving functioning in fibromyalgia patients. We conducted a comprehensive literature search of multiple international databases (PubMed, Scopus, and Web of Science) from their inception until November 22nd, 2023. We identified 23 randomized controlled trials (RCTs) assessing multiple rehabilitation strategies. The primary outcome was the Fibromyalgia Impact Questionnaire (FIQ). Study quality was assessed using the Cochrane Risk-of-Bias Tool for Randomized Trials (RoB 2). The study protocol was registered in PROSPERO (CRD42020197666). Our meta-analysis rehabilitation interventions significantly reduce FIQ scores (MD =-11.74, 95% CI: -16.88 to -6.59, p< 0.0001). Notably, the subgroup analysis showed that different rehabilitation modalities seem to induce different therapeutic responses. Rehabilitation strategies hold promise in addressing the functional impairments and improving the overall well-being of individuals with fibromyalgia. The study underscores the need for further research to determine the optimal rehabilitation approach and its potential impact on the multilevel disability characterizing patients with fibromyalgia.

The aim of this systematic review is to guide the physician in defining the pharmacologic and rehabilitative therapeutic approaches for adopting the best strategies described in the current literature. The search was conducted in PubMed, EMBASE, Cochrane Library and Web of Science to identify the treatment of small fiber neuropathies. Two reviewers independently reviewed and came to a consensus on which articles met inclusion/exclusion criteria. The authors excluded the duplicates, animal studies and included the English articles in which the treatment of patients with small fiber neuropathies was described. The search identified a total of 975 articles with the keywords "small fiber neuropathy" AND "rehabilitation" OR "therapy" OR "treatment". Seventy-eight selected full-text were analyzed by the reviewers. Forty-two publications met the inclusion criteria and were included in the systematic review to describe the rehabilitative and pharmacologic treatment of small fiber neuropathies. Despite the range of different protocols of treatment for small fiber neuropathy, other robust trials are needed. In addition, always different therapeutic approaches are used; a unique protocol could be important for the clinicians. More research is needed to build evidence for the best strategy and to delineate a definitive therapeutic protocol. [ABSTRACT FROM AUTHOR]

The primary analysis of the phase III NIBIT-M2 study showed a 41% 4-year overall survival (OS) of melanoma patients with asymptomatic brain metastases treated with ipilimumab plus nivolumab. Here, we report the 7-year efficacy outcomes and the Health-Related Quality of Life (HRQoL) analyses of the NIBIT-M2 study. As of May 1, 2023, at a median follow-up of 67 months (mo), the median OS was 8.5 (95% CI: 6.6–10.3), 8.2 (95% CI: 2.1–14.3) and 29.2 (95% CI: 0–69.9) mo for the fotemustine (F) Arm A, ipilimumab plus fotemustine Arm B, and ipilimumab plus nivolumab Arm C, respectively. The 7-year OS rate was 10.0% (95% CI: 0–22.5) in Arm A, 10.3% (95% CI: 0–22.6) in Arm B, and 42.8% (95% CI: 23.4–62.2) in Arm C. HRQoL was preserved in all treatment arms. Most functional scales evaluated from baseline to W12 were preserved, with a lower mean score decrease for EORTC Quality of Life Questionnaire (QLQ)-C30 and an increase for EORTC QLQ-Brain neoplasm (BN20) in patients receiving ipilimumab plus nivolumab. With the longest follow-up available to date in melanoma patients with asymptomatic brain metastases, the NIBIT-M2 study continues to show persistent therapeutic efficacy of I ipilimumab plus nivolumab while preserving HRQoL. • Ipilimumab plus nivolumab is effective in asymptomatic melanoma brain metastases. • The NIBIT-M2 study showed persistent efficacy of ipilimumab plus nivolumab at 7-year. • Ipilimumab plus nivolumab may prevent melanoma recurrence in the brain. • Ipilimumab plus nivolumab preserved HRQoL in treated patients. • A meaningful percentage of patients may be cured from therapy.

Background: Congenital disorders of glycosylation (CDG) are genetic diseases caused by impaired synthesis of glycan moieties linked to glycoconjugates. Phosphomannomutase 2 deficiency (PMM2-CDG), the most frequent CDG, is characterized by prominent neurological involvement. Gait disturbance is a major cause of functional disability in patients with PMM2-CDG. However, no specific gait assessment for PMM2-CDG is available. This study analyses gait-related parameters in PMM2-CDG patients using a standardized clinical assessment and instrumented gait analysis (IGA). Results: Seven adult patients with a molecular diagnosis of PMM2-CDG were followed-up from February 2021 to December 2022 and compared to a group of healthy control (HC) subjects, matched for age and sex. Standardized assessment of disease severity including ataxia and peripheral neuropathy along with isometric muscle strength and echo-biometry measurements at lower limbs were performed. IGA spatiotemporal parameters were obtained by means of a wearable sensor in basal conditions. PMM2-CDG patients displayed lower gait speed, stride length, cadence and symmetry index, compared to HC. Significant correlations were found among the used clinical scales and between disease severity (NCRS) scores and the gait speed measured by IGA. Variable reduction of knee extension strength and a significant decrease of lower limb muscle thickness with conserved echo intensity were found in PMM2-CDG compared to HC. Conclusions: The study elucidates different components of gait disturbance in PMM2-CDG patients and shows advantages of using wearable sensor-based IGA in this frame. IGA parameters may potentially serve as quantitative measures for follow-up or outcome quantification in PMM2-CDG. [ABSTRACT FROM AUTHOR]

Despite the relevant research efforts, the causes of amyotrophic lateral sclerosis (ALS) are still unknown and no effective cure is available. Many authors suggest that ALS is a multi-system disease caused by a network failure instead of a cell-autonomous pathology restricted to motoneurons. Although motoneuronal loss is the critical hallmark of ALS given their specific vulnerability, other cell populations, including muscle and glial cells, are involved in disease onset and progression, but unraveling their specific role and crosstalk requires further investigation. In particular, little is known about the plastic changes of the degenerating motor system. These spontaneous compensatory processes are unable to halt the disease progression, but their elucidation and possible use as a therapeutic target represents an important aim of ALS research. Genetic animal models of disease represent useful tools to validate proven hypotheses or to test potential therapies, and the conception of novel hypotheses about ALS causes or the study of pathogenic mechanisms may be advantaged by the use of relatively simple in vivo models recapitulating specific aspects of the disease, thus avoiding the inclusion of too many confounding factors in an experimental setting. Here, we used a neurotoxic model of spinal motoneuron depletion induced by injection of cholera toxin-B saporin in the gastrocnemius muscle to investigate the possible occurrence of compensatory changes in both the muscle and spinal cord. The results showed that, following the lesion, the skeletal muscle became atrophic and displayed electromyographic activity similar to that observed in ALS patients. Moreover, the changes in muscle fiber morphology were different from that observed in ALS models, thus suggesting that some muscular effects of disease may be primary effects instead of being simply caused by denervation. Notably, we found plastic changes in the surviving motoneurons that can produce a functional restoration probably similar to the compensatory changes occurring in disease. These changes could be at least partially driven by glutamatergic signaling, and astrocytes contacting the surviving motoneurons may support this process. [ABSTRACT FROM AUTHOR]

In Italy, the concept of "flood hazard" is adopted to map areas inundated with a fixed frequency or return period, as established by the European Directive 2007/60/CE (Flood directive), and the following Italian laws. The result is the production of "Hydrogeological Structure Plans" (PAI), and later, following the flood directive, "Flood Risk Management Plans" (PGRA), which however cover only main rivers and not secondary rivers and water bodies. In addition, these plans consider the presence of hydraulic defense works (levees, quay walls, drainage canals and detention basins), perfectly functioning, and assume the isofrequency between precipitation and the correspondent flood. Thus, while these plans respond to national laws, they may not provide a clear vision of the inner fragility of the territory.Here, the concept of "susceptibility" is used to map the flood prone areas. The susceptibility defines the probability of a territory to be flooded, and generally is determined according to its geo-litho-morphological and climatic characteristics, regardless of any hydraulic defense work. We considered Apulia region (Southern Italy) as case study. We tested different methods to quantify susceptibility and different geo-litho-morphological and climatic as key factors. We used different data including refund requests made during the commission management of national emergencies, satellite surveys and historically collected information on flood areas. The preliminary results are encouraging and seem to support the use of susceptibility as simple and useful tool for the management of hydraulic risk and the flood emergencies. [ABSTRACT FROM AUTHOR]

Vertebral fragility fractures (VFFs) commonly result from low bone mass and microarchitecture deterioration of bone tissue. spinal orthoses are common non-pharmacological options for managing vertebral fracture pain. However, the effects of spinal orthoses on pain, physical functioning, and quality of life (QoL) are still debated. This survey aimed to investigate the patients-reported outcomes of a dynamic spinal orthosis prescribed in the routine clinical practice of VFFs management. This multi-center national-wide prospective cohort study assessed older patients (aged > 60 years) diagnosed with acute VFFs and prescribed with a dynamic spinal orthosis (Spinfast®). A survey questionnaire was realized and included sections on patient characterization, osteoporosis characterization, spinal orthosis, clinical outcomes, pain medications, and osteoporosis medications. The questionnaire was administered at baseline and after three months. A total of 68 patients completed the questionnaire at three months. Most patients had one or two VFFs and were treated with pain medications and osteoporosis medications. Compliance and tolerability of the spinal orthosis were assessed, and clinical outcomes such as pain intensity, physical functioning, and QoL were measured. The results showed no significant differences in outcomes between age subgroups. Italian physical medicine and rehabilitation physicians were commonly involved in the management of VFFs patients. Sixty-six patients completed the questionnaire. The results showed that pain intensity, physical functioning and QoL improved after three months of spinal orthosis wearing (p< 0.0001). The correct management of VFFs is mandatory to improve pain and reduce disability, and our findings suggested a positive role of dynamic spinal orthosis to improve the comprehensive management of VFFs patients. However, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF. [ABSTRACT FROM AUTHOR]

Despite the recent breakthroughs in targeted and immunotherapy for melanoma, the overall survival rate remains low. In recent years, considerable attention has been paid to the gut microbiota and other modifiable patient factors (e.g., diet and body composition), though their role in influencing therapeutic responses has yet to be defined. Here, we characterized a cohort of 31 patients with unresectable IIIC-IV-stage cutaneous melanoma prior to initiation of targeted or first-line immunotherapy via the following methods: (i) fecal microbiome and metabolome via 16S rRNA amplicon sequencing and gas chromatography/mass spectrometry, respectively, and (ii) anthropometry, body composition, nutritional status, physical activity, biochemical parameters, and immunoprofiling. According to our data, patients subsequently classified as responders were obese (i.e., with high body mass index and high levels of total, visceral, subcutaneous, and intramuscular adipose tissue), non-sarcopenic, and enriched in certain fecal taxa (e.g., Phascolarctobacterium) and metabolites (e.g., anethole), which were potentially endowed with immunostimulatory and oncoprotective activities. On the other hand, non-response was associated with increased proportions of Streptococcus, Actinomyces, Veillonella, Dorea, Fusobacterium, higher neutrophil levels (and a higher neutrophil-to-lymphocyte ratio), and higher fecal levels of butyric acid and its esters, which also correlated with decreased survival. This exploratory study provides an integrated list of potential early prognostic biomarkers that could improve the clinical management of patients with advanced melanoma, in particular by guiding the design of adjuvant therapeutic strategies to improve treatment response and support long-term health improvement.

Introduction: The efficacy of single injections of abobotulinumtoxinA (Dysport) is established in adults with upper limb spasticity. In this study we assessed the effects of repeated injections of abobotulinumtoxinA over 1 year.Methods: Patients (n = 258, safety population) received 500 U, 1,000 U, or 1,500 U (1,500-U dose included 500-U shoulder injections) for up to 4 or 5 treatment cycles. Assessments included treatment-emergent adverse events (TEAEs), muscle tone, passive and active range of motion (XV1, XA ), angle of catch (XV3 ), Disability Assessment Scale (DAS) score, Modified Frenchay Scale (MFS) score, and Physician Global Assessment (PGA) score.Results: The incidence of TEAEs decreased across cycles. Muscle tone reduction and XV1 remained stable across cycles, whereas XV3 and XA continued to improve at the finger, wrist, and elbow flexors. DAS and PGA improved across cycles. MFS improved best with 1,500 U.Discussion: A favorable safety profile and continuous improvements in active movements and perceived and active function were associated with repeated abobotulinumtoxinA injections in upper limb muscles.

The demand for noninvasive methods to assess postural defections is increasing because back alterations are more common among the healthy population. We propose a combined infrared method of rasterstereography and thermography to assess the back without harmful effects. This study aims to provide reference data on rasterstereography and thermography to evaluate the back of a healthy population and to further study the correlation between these two methods. This cross-sectional research involved 175 healthy individuals (85 males and 90 females) aged 22 to 35 years. There is a large Cohen's d effect size in the cervical depth (males = 43.77 ± 10.96 mm vs. females = 34.29 ± 7.04 mm, d = 1.03), and in the lumbar lordosis angle (males = 37.69 ± 8.89° vs. females = 46.49 ± 8.25°, d = − 1.03). The back temperature was different for gender in the cervical area (males = 33.83 ± 0.63 °C vs. females = 34.26 ± 0.84 °C, d = − 0.58) and dorsal area (males = 33.13 ± 0.71 °C vs. females = 33.59 ± 0.97 °C, d = − 0.55). Furthermore, in the female group there was a moderate correlation of lumbar temperature with lumbar lordosis angle (r = − 0.50) and dorsal temperature with shoulders torsion (r = 0.43). Males showed a moderate correlation for vertebral surface rotation RMS with cervical (r = − 0.46), dorsal (r = − 0.60), and lumbar (r = − 0.50) areas and cervical temperature with shoulders obliquity (r = 0.58). These results highlight a possible correlation between rasterstereography and thermography, which may elucidate the underlying mechanics of spinal alterations and thermal muscle response. Our findings may represent reference data for other studies using noninvasive methods to assess postural alterations. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study is to evaluate the impact of total knee arthroplasty (TKA) with the aid of Navio Robot, comparing it with standard prosthetic surgery on the functional outcomes of patients after an intensive rehabilitation program. Method: A case–control observational study was conducted on patients undergoing TKA for severe KOA. All patients underwent the same intensive hospital rehabilitation program of 14 daily sessions lasting 3 h. The following rating scales were administered: Numeric Rating Scale (NRS), Knee Society Score (KSS) and 12-Item Short Form Survey scale. Patient assessments were performed 1 week post-surgery (T0), 1 month post-surgery (T2), and 3 months post-surgery (T3). The primary outcomes were active knee extension and flexion and pain severity. The secondary outcomes were functional capacity and quality of life. Results: Using repeated measures ANOVA, we observed at T1 a statistically different difference for the treatment group compared to the control group about KSS (p < 0.05), pain (p < 0.05), and knee flexion (p < 0.05). No statistically significant difference between the two groups was observed for knee extension (p = 0.09) and the SF-12 scale (p = 0.52). At T2 instead, we observed a statistically significant difference for the treatment group compared to the control group as regards KSS (p < 0.05) and knee flexion (p < 0.05), while no statistically significant difference was observed for pain (p = 0.83), knee extension (p = 0.60), and the SF-12 scale (0.44). Conclusions: Our study has demonstrated that robot-NAVIO assisted knee prosthesis surgery, associated with a specific intensive rehabilitation treatment, in the short and medium term, determines good pain control, better flexion recovery and a improvement of functional capacity.

Background: The various mechanisms involved in peripheral nerve regeneration, induced by exercise and electrical nerve stimulation, are still unclear. Objective: The aim of this review was to summarize the influence of physical exercise and/or electrical stimulation on peripheral nerve repair and regeneration and the variation of impact of intervention depending on timing, as well as kind and dosage of the intervention. A literature survey was conducted on PubMed, Scopus, and Web of Science, between February 2021 to July 2021, with an update in September 2022. Methodology: The literature search identified 101,386 articles with the keywords: "peripheral nerve" OR "neuropathy" AND "sprouting" OR "neuroapraxia" OR "axonotmesis" OR "neurotmesis" OR "muscle denervation" OR "denervated muscle" AND "rehabilitation" OR "physical activity" OR "physical exercise" OR "activity" OR "electrical stimulation". A total of 60 publications were included. Eligible studies were focused on evaluating the process of nerve repair (biopsy, electromyographic parameters or biomarker outcomes) after electrical stimulation or physical exercise interventions on humans or animals with peripheral sensory or motor nerve injury. Synthesis: This study shows that the literature, especially regarding preclinical research, is mainly in agreement that an early physical program with active exercise and/or electrical stimulation promotes axonal regenerative responses and prevents maladaptive response. This was evaluated by means of changes in electrophysiological recordings of CMAPs for latency amplitude, and the sciatic functional index (SFI). Furthermore, this type of activity can cause an increase in weight and in muscle fiber diameter. Nevertheless, some detrimental effects of exercising and electrical stimulation too early after nerve repair were recorded. Conclusion: In most preclinical studies, peripheral neuropathy function was associated with improvements after physical exercise and electrical stimulation. For humans, too little research has been conducted on this topic to reach a complete conclusion. This research supports the need for future studies to test the validity of a possible rehabilitation treatment in humans in cases of peripheral neuropathy to help nerve sprouting.

To evaluate the reasons for inadequate adherence to osteoporosis therapy and to describe the strategies for improving adherence to and persistence with regular medications, we conducted a review of the literature. The primary outcome of the study was the determination of the factors adverse to the onset and maintenance of anti-osteoporosis therapies. Secondly, we focused on studies whose efforts led to finding different strategies to improve adherence and persistence. We identified a total of 26 articles. The most recurrent and significant factors identified were aging, polypharmacy, and smoking habits. Different strategies to guide patients in their osteoporosis care have been identified, such as monitoring and follow-up via telephone calls, email, and promotional meetings, and proactive care interventions such as medication monitoring, post-fracture care programs, and decision aids. Changes in the drugs regimen and dispensation are strategies tried to lead to better adherence and persistence, but also improved satisfaction of patients undergoing anti-osteoporosis treatment. Patient involvement is an important factor to increase medication persistence while using a flexible drugs regimen. [ABSTRACT FROM AUTHOR]

The article offers information on a clinical report of a 50 year old man facing problems in movement of his right index finger and contraction of the corresponding flexor muscles. He has been diagnosed for focal dystonia and the medical personnel used electromyography to study the contractions of the involved muscles. He has been treated with a combination of levodopa, anticholinergic drugs, benzodiazepines and chemodenervation with botulinum toxin.

Background: Patients with stage IIB or IIC melanoma who undergo surgery alone are at a substantial risk for disease recurrence. Adjuvant pembrolizumab significantly improved recurrence-free survival versus placebo in stage IIB or IIC melanoma in the first interim analysis of the KEYNOTE-716 trial. Here, we report results from the secondary endpoint of distant metastasis-free survival (prespecified third interim analysis), and recurrence-free survival with longer follow-up.Methods: KEYNOTE-716 is a multicentre, double-blind, placebo-controlled, crossover or rechallenge, randomised, phase 3 trial done at 160 academic medical centres and hospitals across 16 countries. Eligible patients were aged 12 years and older with newly-diagnosed, completely resected, and histologically confirmed stage IIB (T3b or T4a) or IIC (T4b) cutaneous melanoma; negative sentinel lymph node biopsy; and an Eastern Cooperative Oncology Group performance status of 0-1. Patients were randomly assigned (1:1) to receive either 200 mg of pembrolizumab (2 mg/kg up to a maximum of 200 mg in paediatric patients) or placebo, both intravenously, every 3 weeks for 17 cycles (part 1) or until disease recurrence or unacceptable toxicity. Eligible patients with disease recurrence could receive further treatment with pembrolizumab in the part 2 crossover or rechallenge phase. Randomisation was done using an interactive response technology system and stratified by T category and paediatric status. The primary endpoint was investigator-assessed recurrence-free survival (assessed here with longer follow-up), and we report the prespecified third interim analysis of distant metastasis-free survival (secondary endpoint). Efficacy analyses were done in the intention-to-treat population (all patients who were randomly assigned, according to assigned group) and safety was assessed in all patients who were randomly assigned and received at least one dose of trial treatment, according to the treatment received. KEYNOTE-716 is registered at ClinicalTrials.gov, NCT03553836, and has completed recruitment.Findings: Between Sept 23, 2018, and Nov 4, 2020, 976 patients were randomly assigned to receive pembrolizumab (n=487) or placebo (n=489). At a median follow-up of 27·4 months (IQR 23·1-31·7), median distant metastasis-free survival was not reached (95% CI not reached [NR]-NR) in either group. Pembrolizumab significantly improved distant metastasis-free survival (hazard ratio [HR] 0·64, 95% CI 0·47-0·88, p=0·0029) versus placebo. Median recurrence-free survival was 37·2 months (95% CI NR-NR) in the pembrolizumab group and not reached in the placebo group (95% CI NR-NR). The risk of recurrence remained lower with pembrolizumab versus placebo (HR 0·64, 95% CI 0·50-0·84). The most common grade 3 or worse adverse events were hypertension (16 [3%] of 483 patients in the pembrolizumab group vs 17 [4%] of 486 patients in the placebo group), diarrhoea (eight [2%] vs one [<1%]), rash (seven [1%] vs two [<1%]), autoimmune hepatitis (seven [1%] vs two [<1%]), and increased lipase (six [1%] vs eight [2%]). Treatment-related serious adverse events occurred in 49 (10%) patients in the pembrolizumab group and 11 (2%) patients in the placebo group. No treatment-related deaths were reported.Interpretation: Adjuvant pembrolizumab is an efficacious treatment option for resected stage IIB and IIC melanoma, with significant improvement in distant-metastasis free survival versus placebo and continued reduction in the risk of recurrence with an adverse event profile consistent with previous studies of pembrolizumab. The overall benefit-risk of pembrolizumab continues to be positive in the adjuvant setting.Funding: Merck Sharp & Dohme, a subsidiary of Merck & Co. [ABSTRACT FROM AUTHOR]

Pembrolizumab prolongs progression-free and overall survival among patients with advanced melanoma and recurrence-free survival in resected stage III disease. KEYNOTE-716 assessed pembrolizumab as adjuvant therapy in patients with completely resected, high-risk, stage II melanoma. We report results from the planned first and second interim analyses for recurrence-free survival. In this double-blind, randomised, placebo-controlled phase 3 study, involving 160 academic medical centres and hospitals in 16 countries (Australia, Belgium, Brazil, Canada, Chile, France, Germany, Israel, Italy, Japan, Poland, South Africa, Spain, Switzerland, the UK, and the USA), patients aged 12 years or older with newly diagnosed, completely resected stage IIB or IIC melanoma (TNM stage T3b or T4 with a negative sentinel lymph node biopsy) were recruited. Eligible patients were randomly assigned (1:1), in blocks of four and stratified by T-category (3b, 4a, and 4b) and paediatric status (age 12–17 years vs ≥18 years), using an interactive response technology system to intravenous pembrolizumab 200 mg (2 mg/kg in paediatric patients) or placebo every 3 weeks for 17 cycles or until disease recurrence or unacceptable toxicity. All patients, clinical investigators, and analysts were masked to treatment assignment. The primary endpoint was investigator-assessed recurrence-free survival (defined as time from randomisation to recurrence or death) in the intention-to-treat (ITT) population (ie, all patients randomly assigned to treatment). The primary endpoint was met if recurrence-free survival was significantly improved for pembrolizumab versus placebo at either the first interim analysis (after approximately 128 patients had events) or second interim analysis (after 179 patients had events) under multiplicity control. Safety was assessed in all patients randomly assigned to treatment who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov , NCT03553836 , and is closed to accrual. Between Sept 23, 2018, and Nov 4, 2020, 1182 patients were screened, of whom 976 were randomly assigned to pembrolizumab (n=487) or placebo (n=489; ITT population). The median age was 61 years (IQR 52–69) and 387 (40%) patients were female and 589 (60%) were male. 874 (90%) of 976 patients were White and 799 (82%) were not Hispanic or Latino. 483 (99%) of 487 patients in the pembrolizumab group and 486 (99%) of 489 in the placebo group received assigned treatment. At the first interim analysis (data cutoff on Dec 4, 2020; median follow-up of 14·4 months [IQR 10·2–18·7] in the pembrolizumab group and 14·3 months [10·1–18·7] in the placebo group), 54 (11%) of 487 patients in the pembrolizumab group and 82 (17%) of 489 in the placebo group had a first recurrence of disease or died (hazard ratio [HR] 0·65 [95% CI 0·46–0·92]; p=0·0066). At the second interim analysis (data cutoff on June 21, 2021; median follow-up of 20·9 months [16·7–25·3] in the pembrolizumab group and 20·9 months [16·6–25·3] in the placebo group), 72 (15%) patients in the pembrolizumab group and 115 (24%) in the placebo group had a first recurrence or died (HR 0·61 [95% CI 0·45–0·82]). Median recurrence-free survival was not reached in either group at either assessment timepoint. At the first interim analysis, grade 3–4 treatment-related adverse events occurred in 78 (16%) of 483 patients in the pembrolizumab groups versus 21 (4%) of 486 in the placebo group. At the first interim analysis, four patients died from an adverse event, all in the placebo group (one each due to pneumonia, COVID-19-related pneumonia, suicide, and recurrent cancer), and at the second interim analysis, one additional patient, who was in the pembrolizumab group, died from an adverse event (COVID-19-related pneumonia). No deaths due to study treatment occurred. Pembrolizumab as adjuvant therapy for up to approximately 1 year for stage IIB or IIC melanoma resulted in a significant reduction in the risk of disease recurrence or death versus placebo, with a manageable safety profile.

COMBI-AD demonstrated long-term benefit of adjuvant dabrafenib plus trametinib in patients with resected stage III BRAF V600E/K–mutant melanoma; however, 9% of patients permanently discontinued therapy due to pyrexia. COMBI-APlus evaluated whether an adapted pyrexia management algorithm reduces high-grade pyrexia and pyrexia-related adverse outcomes. COMBI-APlus is an open-label, phase IIIb trial evaluating an adapted pyrexia management algorithm in patients with high-risk resected stage III BRAF V600E/K–mutant melanoma treated with up to 12 months of adjuvant dabrafenib plus trametinib. Both drugs were interrupted for pyrexia (temperature ≥38°C) or the occurrence of pyrexia syndrome for suspected recurrent pyrexia. Treatment was restarted at the same dose once patients were symptom free for ≥24 h. The primary endpoint was the composite rate of grade 3/4 pyrexia, hospitalisation due to pyrexia, or permanent discontinuation due to pyrexia versus historical COMBI-AD control (20.0%; 95% confidence interval [CI], 16.3%–24.1%). At data cutoff (5 October 2020), COMBI-APlus met its primary endpoint of significant improvement in the composite rate of pyrexia (8.0% [95% CI, 5.9%–10.6%]), with rates of 3.8% for grade 3/4 pyrexia, 4.3% for hospitalisation due to pyrexia, and 2.4% for discontinuation due to pyrexia. Estimated 12-month relapse-free survival was 91.8% (95% CI, 89.0%–93.9%). The most common adverse events were consistent with those in COMBI-AD, and 14.7% of patients permanently discontinued treatment due to adverse events. The adapted pyrexia management algorithm appears to reduce the incidence of severe pyrexia outcomes, enables patients to manage pyrexia at home, and helps patients remain on treatment. NCT03551626. • COMBI-APlus met its primary endpoint of reduction in the composite rate of pyrexia. • Pyrexia composite rate = grade 3/4 incidence, hospitalisation, and discontinuation. • The adapted pyrexia management algorithm interrupted both drugs for pyrexia. • Overall safety and early efficacy in COMBI-APlus were consistent with COMBI-AD.

Background: Neurological immune-related adverse events (nirAEs) are rare toxicities of immune-checkpoint inhibitors (ICI). With the increase of ICI oncological indications, their incidence is growing. Their recognition and management remain nevertheless challenging. Methods: A national, web-based database was built to collect cases of neurological symptoms in patients receiving ICI and not attributable to other causes after an adequate workup. Results: We identified 27 patients who developed nirAEs (20 males, median age 69 years). Patients received anti-PD1/PDL1 (78%), anti-CTLA4 (4%), or both (19%). Most common cancers were melanoma (30%) and non-small cell lung cancer (26%). Peripheral nervous system was mostly affected (78%). Median time to onset was 43.5 days and was shorter for peripheral versus central nervous system toxicities (36 versus 144.5 days, p = 0.045). Common manifestations were myositis (33%), inflammatory polyradiculoneuropathies (33%), and myasthenia gravis (19%), alone or in combination, but the spectrum of diagnoses was broad. Most patients received first-line glucocorticoids (85%) or IVIg (15%). Seven patients (26%) needed second-line treatments. At last follow-up, four (15%) patients were deceased (encephalitis, 1; myositis/myasthenia with concomitant myocarditis, 2; acute polyradiculoneuropathy, 1), while seven (26%) had a complete remission, eight (30%) partial improvement, and six (22%) stable/progressing symptoms. ICI treatment was discontinued in most patients (78%). Conclusions: Neurological irAEs are rare but potentially fatal. They primarily affect neuromuscular structures but encompass a broad range of presentations. A prompt recognition is mandatory to timely withheld immunotherapy and administrate glucocorticoids. In corticoresistant or severely affected patients, second-line treatments with IVIg or plasmapheresis may result in additional benefit. [ABSTRACT FROM AUTHOR]

Abstract: Mammalian chitinases consisting of CHIA, CHIT1, CHI3L1, CHI3L2 and CHID1 exert important biological roles in the monocyte lineage and chronic inflammatory diseases. Pathological bone resorption is a cause of significant morbidity in diseases affecting the skeleton such as rheumatoid arthritis, osteoporosis, periodontitis and cancer metastasis. The biologic role of chitinases in bone resorption is poorly understood. In this study, we evaluated the expression of the chitinases family during osteoclast differentiation. The expression of CHIA, CHI3L2 and CHID1 resulted unchanged during osteoclast differentiation, whereas CHIT1 and CHI3L1 increased significantly. We also observed that CHIT1 and CHI3L1 are involved in osteoclast function. Indeed, silencing CHIT1 and CHI3L1 with siRNA resulted in a significant decrease in bone resorption activity. In addition, transfection with CHIT1 or CHI3L1 siRNA and co-transfection with both decreased the levels of the pro-differentiative marker MMP9. Overall, these discoveries reveal a novel and crucial role for both CHIT1 and CHI3L1 in promoting bone resorption and identifying new potential candidate markers for therapeutic targeting.

Parts 4 and 5 of the phase 1/2 KEYNOTE-022 study investigated the maximum tolerated dose (MTD), safety, and efficacy of pembrolizumab plus trametinib in solid tumours and BRAF wild-type melanoma. Patients received intermittent or concurrent dosing of pembrolizumab plus trametinib. Concurrent dosing was 2 or 4 weeks of trametinib run-in followed by concurrent pembrolizumab every 3 weeks (Q3W) plus trametinib once daily (QD). Intermittent dosing was 2 weeks of trametinib run-in followed by pembrolizumab plus intermittent trametinib (1 week off/2 weeks on). A 3 + 3 dose escalation was used, followed by dose confirmation. Forty-two patients were enrolled. No dose-limiting toxicities (DLTs) occurred at initial dose levels (DL). At subsequent DLs, 10 of 38 evaluable patients had DLTs. For concurrent dosing, MTD was pembrolizumab 200 mg Q3W plus trametinib 1.5 mg QD, with a 2-week trametinib 1.5 mg QD run-in (concurrent DL2a); in concurrent DL2a group, five (31%) patients had grade 3/4 treatment-related adverse events (TRAEs); the objective response rate (ORR) was 0%. ORR was 40% in concurrent DL1 and 0% in concurrent DL2b. For intermittent dosing, MTD was pembrolizumab 200 mg Q3W plus trametinib 2 mg QD with a 2-week trametinib 2 mg QD run-in (intermittent DL2); in the intermittent DL2 group, seven (47%) patients had grade 3/4 TRAEs; ORR was 27%. ORR in intermittent DL1 was 33%. MTDs for concurrent and intermittent dosing of pembrolizumab with trametinib were identified. The combination had limited antitumour activity, numerically higher ORR with intermittent versus concurrent dosing, and manageable safety. NCT02130466. • Pembrolizumab plus trametinib was investigated in parts 4 and 5 of KEYNOTE-022. • Patients in parts 4 and 5 had BRAF wild-type melanoma or solid tumours. • Maximum tolerated doses were identified for concurrent and intermittent dosing. • The safety profile of pembrolizumab plus trametinib was manageable. • Limited antitumour activity was observed; further investigation is warranted.

• With sequential CIRT and ICIs G3+ AEs are observed in 21% of patients. • Late AEs may be observed in 79% of patients treated with sequential CIRT and ICIs. • The frequency of G3+ local AEs is similar to what is observed with CIRT alone. • The frequency of G3+ AEs is similar to what is observed with ICI without CIRT. We analyzed CTCAE adverse events of sequential Carbon Ion radiotherapy (CIRT) and immune checkpoint inhibitors (ICIs) in advanced melanoma patients. The frequencies of early and late adverse events (AEs) were 100% and 82% of patients, respectively. The frequency of G3+ AEs was in line with the literature. [ABSTRACT FROM AUTHOR]

During the Tenth Edition of the Annual Congress on "Anticancer Innovative Therapy" [Milan, 23/24 January 2020], experts in the fields of immuno-oncology, epigenetics, tumor cell signaling, and cancer metabolism shared their latest knowledge on the roles of i] epigenetics, and in particular, chromatin modifiers, ii] cancer metabolism, iii] cancer stem cells [CSCs], iv] tumor cell signaling, and iv] the immune system. The novel therapeutic approaches presented included epigenetic drugs, cell cycle inhibitors combined with ICB, antibiotics and other off-label drugs, small-molecules active against CSCs, liposome-delivered miRNAs, tumor-specific CAR-T cells, and T-cell–based immunotherapy. Moreover, important evidence on possible mechanisms of resistance to these innovative therapies were also discussed, in particular with respect to resistance to ICB. Overall, this conference provided scientists and clinicians with a broad overview of future challenges and hopes to improve cancer treatment reasonably in the medium-short term.

Background and aim: In the scientific literature, there is unanimous consensus that hospitalization in stroke unit (SU) is the most important treatment for stroke patients. In this regard, the Act number 70/2015 by the Italian government identified specific skills that contribute to a classification of SU and outlined a "hub and spoke" stroke network. The aim of our study was to check the coverage of requirements of first and second level SU in the national territory and to shed light on any deficit or misdistribution of resources. Material and methods: In 2019, a survey on the current situation related to stroke care in Italy was carried out by the Italian Society of Neurology (SIN), The Italian Stroke Organization (ISO), and the Association for the Fight against Stroke (A.L.I.Ce). Results: First level SU was found to be 58 against a requirement, according to the Act 70/2015, of 240. Second level SU was found to be 52 compared with an expected requirement of 60. Neurointerventionists were 280 nationally, with a requirement of 240. A misdistribution of resources within individual regions was often seen. Conclusions: The survey demonstrated a severe shortage of beds dedicated to cerebrovascular diseases, mainly because of lack of first level SU, especially in central and southern Italy. It also suggests that the current hub and spoke system is not yet fully implemented across the country and that resources should be better distributed in order to ensure uniform and fair care for all stroke patients on the whole territory.

• CIRT in Head and Neck Mucosal Melanoma (HNMM) is safe and locally effective. • CIRT for HNMM is safe both in unresected and postoperative setting. • Multidisciplinary management of HNMM in high expertise referral centers is crucial. • Immunotherapy after CIRT may provide potential survival advantage. • Prospective studies are needed to investigate the role of immunotherapy after CIRT. To evaluate efficacy and toxicity of carbon ion radiotherapy (CIRT) in locally advanced head and neck mucosal melanoma (HNMM) patients treated at our Institute. Between June 2013 and June 2020, 40 HNMM patients were treated with CIRT. Prescription dose was 65.6-68.8 Gy relative biological effectiveness [RBE] in 16 fractions. Twelve (30%) patients received only biopsy, 28 (70%) surgical resection before CIRT. Immunotherapy was administered before and/or after CIRT in 45% of patients, mainly for distant progression (89%). Median follow-up was 18 months. 2-year Local Relapse Free Survival (LRFS), Overall Survival (OS), Progression Free Survival (PFS) and Distant Metastasis Free Survival (DMFS) were 84.5%, 58.6%, 33.2% and 37.3%, respectively. At univariate analysis, LRFS was significantly better for non-recurrent status, < 2 surgeries before CIRT and treatment started < 9 months from the initial diagnosis, with no significant differences for operated versus unresected patients. After relapse, immunotherapy provided longer median OS (17 months vs 3.6, p-value<0.001). Late toxicity ≥ G3 (graded with CTCAE 5.0 scale) was reported in 10% of patients. CIRT in advanced HNMM patients is safe and locally effective. Prospective trials are warranted to assess the role of targeted/immune- systemic therapy to improve OS. [ABSTRACT FROM AUTHOR]

This systematic review describes the several methods to diagnose and measure the severity of small fiber neuropathies and aims to guide the physician to define all the diagnostic approaches for adopting the best strategies described in the current literature. The search was conducted in PubMed, EMBASE, Cochrane Library and Web of Science. Two reviewers independently reviewed and came to consensus on which articles met inclusion/exclusion criteria. The authors excluded all the duplicates, animals' studies, and included the English articles in which the diagnostic measures were finalized to assess the effectiveness of rehabilitation and pharmacologic treatment of patients with small fiber neuropathies. The search identified a total of 975 articles with the keywords "small fiber neuropathy" AND "rehabilitation" OR "therapy" OR "treatment". Seventy-eight selected full-text were analyzed by the reviewers. Forty-one publications met the inclusion criteria and were included in the systematic review. Despite the range of diagnostic tools for the assessment of small fiber neuropathy, other robust trials are needed. In addition, always different diagnostic approaches are used, a unique protocol could be important for the clinicians. More research is needed to build evidence for the best diagnostic methodologies and to delineate a definitive diagnostic protocol. [ABSTRACT FROM AUTHOR]

Objective: immunotherapy with immune checkpoint inhibitors has become one of the standard therapeutic modalities for patients with advanced melanoma. Melanoma of the female lower genital tract is a rare and aggressive disease, with poor long-term clinical outcomes. To date, no study evaluated the role of immunotherapy in metastatic melanoma of the lower genital tract. Methods: Data of women with metastatic melanoma of the lower genital tract were prospectively collected. Survival outcomes over time was assessed using Kaplan-Meier model. Results: Seven cases of metastatic melanoma of the lower genital tract (vulva [n=2], vagina [n=4], and uterine cervix [n=1]) treated with immune checkpoint inhibitors are reviewed. Two patients had metastatic disease at diagnosis, while 5 patients developed metastatic disease at a mean (standard deviation) time of 9.9 (±3.0) months from primary diagnosis. Four patients received an anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA4) (ipilimumab) and 3 received an anti-programmed cell death 1 (PD-1) (pembrolizumab [n=2], nivolumab [n=1]) therapy. The response rate to immunotherapy was 28.5%. Patients receiving an anti-PD-1 experienced a better progression-free survival than patients treated with anti-CTLA4 (p=0.01, log-rank test). Although not reaching statistical significance, overall survival was better in patients having an anti-PD-1 therapy in comparison to anti- CTLA4 (p=0.15, log-rank test). Conclusion: Results from our series confirm the poor prognosis of women with metastatic melanoma of the lower genital tract, thus supporting the need of exploring new treatment modalities. Further studies are warranted to improve knowledge on the role of immunotherapy in metastatic melanoma of the lower genital tract. [ABSTRACT FROM AUTHOR]

Introduction: Intra‐articular injections of various drugs are commonly used in patients with degenerative osteoarthritis and also in haemophilic patients. Haemophilic arthropathy is a particular type of secondary osteoarthritis (OA), but the degeneration of strong synovial, cartilaginous and subchondral constituents is provoked by the direct action of iron and blood in the joint. Aim of the study: The aim of this study is to review the literature regarding the use of various intra‐articular drugs in joints affected by haemophilic arthropathy. Methods: We reviewed the data from the literature; the search was performed on three medical electronic databases (PubMed, Cochrane Library and Scopus Web of Science) by three authors (B. E., A. M. and V. N.) from 3 December 2018 till 15 December 2018. The search string was as follows: (hyaluronic acid OR viscosupplementation OR platelet‐rich plasma OR corticosteroid OR mesenchymal stem cells) AND (haemophilia OR haemophilic arthropathy OR haemophilic arthritis). Results: Once the research was performed, a total of 300 articles were identified. 47 selected articles were analysed by the reviewers, and the eligibility of the study inclusion was assessed independently. Twelve papers were included based on clear fulfilment of the inclusion criteria. Thirty‐five articles were excluded for the following reasons: no full text or accessible data for 14 of them, 15 involved surgery or rehabilitation therapy as the primary topic and 6 were systematic reviews (the main topics were beyond the haemophilic arthropathy). Conclusion: Although the degree of scientific evidence of the publications on intra‐articular injections of various drugs (hyaluronic acid, corticosteriods, PRP and MSCs) in haemophilia is very low, it seems that intra‐articular injections of hyaluronic acid can relieve joint pain for months and can be repeated every 6‐12 months, which is why they can be recommended. Corticosteroid injections seem to relieve joint pain for a few weeks, but their routine use is not recommended in haemophilia.

Background: Therapeutic chances for metastatic melanoma have consistently changed over the last years with the advent of antibodies targeting the programmed cell death protein-1 (PD-1). Onset of immune-related adverse events (irAEs) during treatment can be a source of concern, and the association with survival outcome is yet to be defined.Patients and methods: Data of consecutive patients treated with anti-PD1 (nivolumab or pembrolizumab) for metastatic melanoma between July 2013 and January 2018 were retrospectively reviewed. Baseline factors, together with onset of irAEs and vitiligo during treatment, were evaluated to identify predictors of progression-free (PFS) and overall (OS) survival. PFS and OS were assessed using Kaplan-Meier and Cox models.Results: Overall, 173 patients were included in the present analysis, and 102 patients (59%) experienced irAEs. Disease control rate was 51%. Median (interquartile range) PFS and OS were 4.9 (2.6-13.3) and 8.6 (3.5-18.3) months, respectively. At multivariate analysis, irAEs occurrence was independently associated with improved PFS [HR 0.47 (95% CI 0.26, 0.86); p = 0.016], and correlated with better OS [HR 0.39 (95% CI 0.18, 0.81); p = 0.007]. Among various irAEs, the occurrence of vitiligo was associated with a trend toward a non-significant improved OS in comparison with other irAEs (p = 0.061). Median OS was undefined for patients experiencing vitiligo vs. 21.9 months for patients with other irAEs vs. 9.7 months for patients who had no irAEs (p = 0.003).Conclusions: Our study underlines the association between irAEs and survival outcomes from anti-PD1 therapy. Careful management of treatment-related toxicity can lead to achieve maximum clinical benefit from this therapy. [ABSTRACT FROM AUTHOR]

Abstract Background The oncogenic BRAF inhibitor vemurafenib improves outcomes for patients with advanced BRAF V600 mutation-positive melanoma compared with cytotoxic chemotherapy. Vemurafenib is now approved for use in this patient population. Patients and methods In this open-label, multicentre study, patients with previously treated or untreated melanoma and the BRAF V600 mutation received vemurafenib 960 mg twice daily. The primary endpoint was safety. In a post hoc analysis, overall survival (OS) was analysed according to a prognostic scoring system developed using Eastern Cooperative Oncology Group performance status, existence of brain metastases and baseline serum lactate dehydrogenase level. The index was validated using data from patients treated with vemurafenib or dacarbazine in three clinical trials and data from patients treated with vemurafenib plus cobimetinib in two studies. The study is registered with ClinicalTrials.gov (NCT01307397). Results Between March 2011 and January 2013, 3224 patients were enrolled, and 3219 patients received ≥1 dose of vemurafenib (safety population); median follow-up time was 33.4 months. Vemurafenib's long-term benefits were confirmed, and no new safety signals identified. The prognostic index showed between-group differences in OS, with tight, non-overlapping confidence intervals. Validation in a pooled group of 666 vemurafenib-treated clinical trial patients revealed a similar pattern; the pattern was similar in 280 patients treated with vemurafenib plus cobimetinib. Conclusions Final results from the vemurafenib safety study confirm vemurafenib's tolerability in BRAF V600 mutation-positive patients and resemble those seen in real-world clinical practice. This index may be useful in patients on combination therapy and as a basis for further work. Highlights • Vemurafenib was generally tolerable in patients with metastatic melanoma. • We developed a prognostic index that allowed estimation of overall survival. • The prognostic index showed survival differences, with tight, non-overlapping confidence intervals. • Validation in vemurafenib-treated clinical trial patients revealed a similar pattern. • This prognostic index may be useful as a basis for further studies.

Background and Objective: Immuno-oncology therapies represent a new treatment opportunity for patients affected by metastatic melanoma. The purpose of this study was to estimate the costs of immune-related adverse events (irAEs) associated with the new anti-PD1 immuno-oncology therapies, with the anti-CTLA-4 immuno-oncology therapy and with the combined therapy (CTLA4 + anti-PD1) in patients affected by metastatic melanoma.Materials and Methods: A probabilistic cost-of-illness (COI) model was developed to estimate the management costs of grade ≥ 3 adverse events associated with the new anti-PD1 therapies (pembrolizumab and nivolumab), the anti-CTLA-4 therapy (ipilimumab) and the combined therapy CTLA4 + anti-PD1 (nivolumab + ipilimumab) for the treatment of patients with metastatic melanoma from the National Health Service (NHS) perspective in Italy. Identification of the epidemiological and cost parameters was carried out through a systematic literature review (SLR). Univariate and probabilistic sensitivity analyses were performed to account for uncertainty and variation in the model results.Results: The model estimated a cost associated with the management of grade ≥ 3 immune-related adverse events in patients with metastatic melanoma equal to €176.2 (95% CI 63.5-335.0) for anti-CTLA-4 therapy, €48.6 (95% CI 40.1-58.5) for the new anti-PDI therapies and €276.8 (95% CI 240.4-316.2) for the combined therapy. Among the innovative therapies for the considered metastatic melanoma, the combined therapy was the most expensive innovative treatment in terms of event management of immune-related grade ≥ 3 adverse events.Conclusion: This study may represent a useful tool to understand the economic burden associated with the management of irAEs associated with patients affected by metastatic melanoma.

Objective The incidence of brain metastases from melanoma is increasing. Several effective treatment options are now available but what can be considered the optimal therapeutic strategy is not yet defined. We evaluated the outcome of patients with brain metastatic melanoma in terms of local control rate, brain distant progression, and overall survival. Methods The present retrospective study includes only patients with limited brain metastases (≤4) who underwent surgery plus stereotactic radiosurgery (SRS), or SRS alone. Surgical resection was performed in patients with good Karnofsky performance score, single large brain lesions, controlled extracranial disease, and SRS alone in all other cases. Supramargical resection was performed in all patients. The prescribed radiotherapy doses were 24 Gy/1 fraction and 30 Gy in 3–5 fractions for lesions >2.5 cm. Clinical outcome was evaluated by brain magnetic resonance imaging performed 2 months after radiotherapy and then every 3 months. Results From April 2011 to October 2015, 53 patients were treated. The median age was 54 years (range, 29–82 years). Most of patients had 1–2 brain metastases (86.8%). Twelve patients (22.6%) underwent surgical resection followed by SRS on the tumor bed, and 41 (77.4%) received SRS alone. The median follow-up time was 20.9 months (range, 5.7–61.3 months). The median, 1-, 2-, 3-year overall survival were 11.8 months, 47.2%, 28%, and 21.8%, respectively. Factors recorded as influencing survival were the number of brain metastases, the melanoma-specific graded prognostic assessment score, and BRAF mutated status. Conclusions Our data identifier a subset of patients with a more favorable outcome who could take advantage of a more aggressive local approach followed by targeted therapy. [ABSTRACT FROM AUTHOR]

Background The orally available BRAF kinase inhibitor vemurafenib is an effective and tolerable treatment option for patients with metastatic melanoma harbouring BRAF V600 mutations. We assessed the safety of vemurafenib in a large population of patients with few alternative treatment options; we report updated 2-year safety. Methods This was an open-label, multicentre study of vemurafenib (960 mg bid) in patients with previously treated or untreated BRAF mutation-positive metastatic melanoma (cobas ® 4800 BRAF V600 Mutation Test). The primary end-point was safety; efficacy end-points were secondary. An exploratory analysis was performed to assess safety outcomes in patients with long duration of response (DOR) (≥12 or ≥24 months). Results After a median follow-up of 32.2 months (95% CI, 31.1–33.2 months), 3079/3219 patients (96%) had discontinued treatment. Adverse events (AEs) were largely consistent with previous reports; the most common all-grade treatment-related AEs were arthralgia (37%), alopecia (25%) and hyperkeratosis (23%); the most common grade 3/4 treatment-related AEs were squamous cell carcinoma of the skin (8%) and keratoacanthoma (8%). In the exploratory analysis, patients with DOR ≥12 months (n = 287) or ≥24 months (n = 133) were more likely to experience grade 3/4 AEs than the overall population. No new specific safety signals were observed with longer vemurafenib exposure. Conclusions After 2 years' follow-up, safety was maintained in this large group of patients with BRAF V600 mutation-positive metastatic melanoma who are more representative of routine clinical practice than typical clinical trial populations. These data suggest that long-term vemurafenib treatment is effective and tolerable without the development of new safety signals. [ABSTRACT FROM AUTHOR]

Background: Dabrafenib plus trametinib improves clinical outcomes in BRAFV600-mutant metastatic melanoma without brain metastases; however, the activity of dabrafenib plus trametinib has not been studied in active melanoma brain metastases. Here, we report results from the phase 2 COMBI-MB trial. Our aim was to build on the current body of evidence of targeted therapy in melanoma brain metastases through an evaluation of dabrafenib plus trametinib in patients with BRAFV600-mutant melanoma brain metastases.Methods: This ongoing, multicentre, multicohort, open-label, phase 2 study evaluated oral dabrafenib (150 mg twice per day) plus oral trametinib (2 mg once per day) in four patient cohorts with melanoma brain metastases enrolled from 32 hospitals and institutions in Europe, North America, and Australia: (A) BRAFV600E-positive, asymptomatic melanoma brain metastases, with no previous local brain therapy, and an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; (B) BRAFV600E-positive, asymptomatic melanoma brain metastases, with previous local brain therapy, and an ECOG performance status of 0 or 1; (C) BRAFV600D/K/R-positive, asymptomatic melanoma brain metastases, with or without previous local brain therapy, and an ECOG performance status of 0 or 1; and (D) BRAFV600D/E/K/R-positive, symptomatic melanoma brain metastases, with or without previous local brain therapy, and an ECOG performance status of 0, 1, or 2. The primary endpoint was investigator-assessed intracranial response in cohort A in the all-treated-patients population. Secondary endpoints included intracranial response in cohorts B, C, and D. This study is registered with ClinicalTrials.gov, number NCT02039947.Findings: Between Feb 28, 2014, and Aug 5, 2016, 125 patients were enrolled in the study: 76 patients in cohort A; 16 patients in cohort B; 16 patients in cohort C; and 17 patients in cohort D. At the data cutoff (Nov 28, 2016) after a median follow-up of 8·5 months (IQR 5·5-14·0), 44 (58%; 95% CI 46-69) of 76 patients in cohort A achieved an intracranial response. Intracranial response by investigator assessment was also achieved in nine (56%; 95% CI 30-80) of 16 patients in cohort B, seven (44%; 20-70) of 16 patients in cohort C, and ten (59%; 33-82) of 17 patients in cohort D. The most common serious adverse events related to study treatment were pyrexia for dabrafenib (eight [6%] of 125 patients) and decreased ejection fraction (five [4%]) for trametinib. The most common grade 3 or worse adverse events, regardless of study drug relationship, were pyrexia (four [3%] of 125) and headache (three [2%]).Interpretation: Dabrafenib plus trametinib was active with a manageable safety profile in this melanoma population that was consistent with previous dabrafenib plus trametinib studies in patients with BRAFV600-mutant melanoma without brain metastases, but the median duration of response was relatively short. These results provide evidence of clinical benefit with dabrafenib plus trametinib and support the need for additional research to further improve outcomes in patients with melanoma brain metastases.Funding: Novartis.

Background: There are no established therapies specific for NRAS-mutant melanoma despite the emergence of immunotherapy. We aimed to assess the efficacy and safety of the MEK inhibitor binimetinib versus that of dacarbazine in patients with advanced NRAS-mutant melanoma.Methods: NEMO is an ongoing, randomised, open-label phase 3 study done at 118 hospitals in 26 countries. Patients with advanced, unresectable, American Joint Committee on Cancer stage IIIC or stage IV NRAS-mutant melanoma who were previously untreated or had progressed on or after previous immunotherapy were randomised (2:1) to receive either binimetinib 45 mg orally twice daily or dacarbazine 1000 mg/m2 intravenously every 3 weeks. Randomisation was stratified by stage, performance status, and previous immunotherapy. The primary endpoint was progression-free survival assessed by blinded central review in the intention-to-treat population. Safety analyses were done in the safety population, consisting of all patients who received at least one study drug dose and one post-baseline safety assessment. This study is registered with ClinicalTrials.gov, number NCT01763164 and with EudraCT, number 2012-003593-51.Findings: Between Aug 19, 2013, and April 28, 2015, 402 patients were enrolled and randomly assigned, 269 to binimetinib and 133 to dacarbazine. Median follow-up was 1·7 months (IQR 1·4-4·1). Median progression-free survival was 2·8 months (95% CI 2·8-3·6) in the binimetinib group and 1·5 months (1·5-1·7) in the dacarbazine group (hazard ratio 0·62 [95% CI 0·47-0·80]; one-sided p<0·001). Grade 3-4 adverse events seen in at least 5% of patients the safety population in either group were increased creatine phosphokinase (52 [19%] of 269 patients in the binimetinib group vs none of 114 in the dacarbazine group), hypertension (20 [7%] vs two [2%]), anaemia (five [2%] vs six [5%]), and neutropenia (two [1%] vs ten [9%]). Serious adverse events (all grades) occurred in 91 (34%) patients in the binimetinib group and 25 (22%) patients in the dacarbazine group.Interpretation: Binimetinib improved progression-free survival compared with dacarbazine and was tolerable. Binimetinib might represent a new treatment option for patients with NRAS-mutant melanoma after failure of immunotherapy.Funding: Array BioPharma and Novartis Pharmaceuticals Corporation.

Array-comparative genomic hybridization (Array-CGH) has been proposed as the first efficient approach to scan the entire genome for variations in DNA copy number. This diagnostic method is based on the study of total genomic DNA isolated from any sample and reference cell populations, differentially labelled and hybridized to DNA microarrays. The method has been initially applied in clinical genetics research and has recently also been used in cancer research, as tumor genomes have a wide variety of copy number phenotypes, indicating different types of genetic instability. In this field, array-CGH has been demonstrated to be an efficient diagnostic method to provide information on the location of important cancer genes. Recently the use of array-CGH has been expanded, including the analysis of constitutional abnormalities, to diagnose subtending mutations of neurologic diseases, with promising results in diagnosing genetic mutations otherwise not evident with other genetic tests. We performed a prospective study on the efficiency of array-CGH in the genetic-molecular diagnosis of pediatric patients affected by developmental delay and mental retardation associated with clinical signs of dimorphism and/or other relevant neurological symptoms. In our study, we had a detection rate of 22.71% by array-CGH analysis and we were able to take more precise genetic information for microdeletion and microduplication of our cohort of patients with developmental delay and/or idiopathic mental retardation and/or dimorphic face and/or epilepsy. In our opinion, we think that these findings would be helpful in early diagnosis and family genetic counseling, above all in those clinical neurologic cases in which other diagnostic tests have not succeed in performing a diagnosis.

Background: Hepatitis C virus infection and interferon treatment are often associated with anxiety, depressive symptoms and poor health-related quality of life. To evaluate the Silybin-vitamin E-phospholipids complex effect on work ability and whether health related factors (anxiety and depression) were associated with work ability in subjects with chronic hepatitis C treated with Pegylated-Interferon-α2b (Peg-IFN) and Ribavirin (RBV). Methods: Thirty-one patients (Group A) with chronic hepatitis and other 31 subjects in Group B were recruited in a randomized, prospective, placebo controlled, double blind clinical trial. Group A received 1.5 mg/kg per week of Peg-IFN plus RBV and placebo, while Group B received the same dosage of Peg-IFN plus RBV plus association of Silybin 94 mg + vitamin E 30 mg + phospholipids 194 mg in pills for 12 months. All subjects underwent to laboratory exams and questionnaires to evaluate depression (Beck Depression Inventory - BDI), anxiety (State-trait anxiety inventory - STAI) and work ability (Work ability Index - WAI). Results: The comparison between group A and group B showed significant differences after 6 months in ALT (P < 0.001), and viremia (P < 0.05), after 12 months in ALT (P < 0.001), and AST (P < 0.001), at follow up in AST (P < 0.05), and ALT (P < 0.001). Significant difference were observed after 1 month in WAI (p < 0.001) and BDI (P < 0.05), after 6 months in WAI (P < 0.05) and STAI (P < 0.05), after 12 months and at follow up in WAI, STAI and BDI (p < 0.01). Conclusions: The supplementation with Silybin-vitamin E -phospholipids complex increased work ability and reduced depression and anxiety in patients treated with Peg-IFN and RBV.

Glial activation and related neuroinflammatory processes play a key role in the aging and progression of Alzheimer's disease (AD). CHI3L1 / YKL40 is a widely investigated chitinase in neurodegenerative diseases and recent studies have shown its involvement in aging and AD. Nevertheless, the biological function of CHI3L1 in AD is still unknown. Here, we collected microarray datasets from the National Center for Biotechnology Information (NCBI) brain samples of not demented healthy controls (NDHC) who died from causes not attributable to neurodegenerative disorders (n = 460), and of deceased patients suffering from Alzheimer's disease (AD) (n = 697). The NDHC and AD patients were stratified according to CHI3L1 expression levels as a cut-off. We identified two groups both males and females, subsequently used for our statistical comparisons: the high CHI3L1 expression group (HCEG) and the low CHI3L1 expression group (LCEG). Comparing HCEG to LCEG, we attained four signatures according to the sex of patients, in order to identify the healthy and AD brain cellular architecture, performing a genomic deconvolution analysis. We used neurological signatures (NS) belonging to six neurological cells populations and nine signatures that included the main physiological neurological processes. We discovered that, in the brains of NDHC the high expression levels of CHI3L1 were associated with astrocyte activation profile, while in AD males and females we showed an inflammatory profile microglia-mediated. The low CHI3L1 brain expression levels in NDHC and AD patients highlighted a neuronal activation profile. Furthermore, using drugs opposing CHI3L1 transcriptomic signatures, we found a specific drug profile for AD males and females characterized by high levels of CHI3L1 composed of fostamatinib, rucaparib, cephaeline, prednisolone, and dinoprostone. Brain levels of CHI3L1 in AD patients represent a biological signature that allows distinguishing between males and females and their likely cellular brain architecture. • Deconvolution method represents a new approach to define the brain cells' architecture AD. • CHI3L1 is a chitinase high modulated in neurodegenerative diseases and AD. • In AD brains the high expression levels of CHI3L1 were associated with an inflammatory profile. • Neuronal activation profile is significantly activated in AD patients with low CHI3L1 expression. • Anti-AD drugs identified by L1000FWD showed fostamatinib, rucaparib, cephaeline, prednisolone, and Dinoprostone.
