Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has led to an increasing demand for online psychological intervention. The aim of this study is to evaluate the efficacy of received support in internet-based psychological intervention group (I-IG) patients, compared with a wait-list control group (CG). The Impact of Event Scale—Revised, Patient Health Questionnaire 9-item and Generalized Anxiety Disorder scale 7-item were administered. After participants had used the internet-based solution, the System Usability Scale was administered. In total, 221 patients (194 patients supported by internet-based interventions and 27 patients supported onsite) were included in intervention group, and 194 patients were included in CG. In a 6-month follow-up, participants in the I-IG demonstrated significant improvements in terms of PTSD risk (p < 0.0001, d = 0.64), depression (p < 0.0001, d = 0.68), and anxiety (p < 0.0001, d = 1.33), compared to the CG. Significant improvements in onsite intervention group patients with a large to very large effect size of PTSD risk (p < 0.0001, d = 0.91), depression (p < 0.0001, d = 0.81), and anxiety (p < 0.0001, d = 1.62) were found. After internet-based solution use, I-IG patients reported a very high usability and functionality (72.87 ± 13.11) of online intervention. In conclusion, SARS-CoV-2-related mental health problems can be improved by internet-based psychological intervention. The usability and functionality evaluation of online solutions by technological tools showed very positive results for the I-IG patients.

Background: Emotion recognition skills are predicted to be fundamental features in social robots. Since facial detection and recognition algorithms are compute-intensive operations, it needs to identify methods that can parallelize the algorithmic operations for large-scale information exchange in real time. The study aims were to identify if traditional machine learning algorithms could be used to assess every user emotions separately, to relate emotion recognizing in two robotic modalities: static or motion robot, and to evaluate the acceptability and usability of assistive robot from an end-user point of view., Methods: Twenty-seven hospital employees (M = 12; F = 15) were recruited to perform the experiment showing 60 positive, negative, or neutral images selected in the International Affective Picture System (IAPS) database. The experiment was performed with the Pepper robot. Concerning experimental phase with Pepper in active mode, a concordant mimicry was programmed based on types of images (positive, negative, and neutral). During the experimentation, the images were shown by a tablet on robot chest and a web interface lasting 7 s for each slide. For each image, the participants were asked to perform a subjective assessment of the perceived emotional experience using the Self-Assessment Manikin (SAM). After participants used robotic solution, Almere model questionnaire (AMQ) and system usability scale (SUS) were administered to assess acceptability, usability, and functionality of robotic solution. Analysis wasperformed on video recordings. The evaluation of three types of attitude (positive, negative, andneutral) wasperformed through two classification algorithms of machine learning: k-nearest neighbors (KNN) and random forest (RF)., Results: According to the analysis of emotions performed on the recorded videos, RF algorithm performance wasbetter in terms of accuracy (mean ± sd = 0.98 ± 0.01) and execution time (mean ± sd = 5.73 ± 0.86 s) than KNN algorithm. By RF algorithm, all neutral, positive and negative attitudes had an equal and high precision (mean = 0.98) and F-measure (mean = 0.98). Most of the participants confirmed a high level of usability and acceptability of the robotic solution., Conclusions: RF algorithm performance was better in terms of accuracy and execution time than KNN algorithm. The robot was not a disturbing factor in the arousal of emotions.

Background: The Pilots for Healthy and Active Ageing (PHArA-ON) project aimsto ensure reality smart and active living for Europe's ageing population by creating a set of integrated and highly customizable interoperable open platforms with advanced services, devices, and technologies and tools. The aim of the present study was to determine the needs and preferences of older people and their caregivers for improving healthy and active aging and guiding the technological development of thePHArA-ON system., Methods: A pre-structured interview was administered to older adults, informal caregivers and professional caregivers (including social operators) taking part in the piloting sessions., Results: Interviews were carried out in Umana Persone Social Enterprise R&D Network (UP) in Tuscany, and Ospedale Casa SollievodellaSofferenza (CSS) in Apulia. A total of 22 older adults, 22 informal caregivers, 13 professional caregivers and 4 social operators were recruited. A prioritization analysis of services, according to the stakeholder's needs, has determined two fundamental need categories: Heath Management (i.e., stimulation and monitoring), and Socialisation (i.e., promoting social inclusion)., Conclusions: The main scientific contributions to this study are the following: to design and evaluate technology in the context of healthy and active ageing, to acquire relevant knowledge on user needs to develop technologies that can handle the real life situations of older people, obtain useful insights about the attitude and availability of end-users in using technologies in clinical practice, and to provide important guidelines to improve the PHArA-ON system. Specific experimentation stages were also carried out to understand which kind of technology is more acceptable, and to obtain feedback regarding the development priority related to the impact of the proposed services. Research through fruitful and continuous interaction with the different subjects involved in the development process of the system, as well as with stakeholders, enabled the implementation of a platform which could be further and easily integrated and improved.

Background and Objectives: Conflicting evidence is reported regarding any association between colonic diverticula with colorectal adenomas or cancer. The present study aimed to evaluate, in a cohort of Caucasian patients, the association between colonic diverticula and colorectal polyps and cancer. Materials and Methods: All consecutive patients undergoing colonoscopy at our institution were included in the study. The presence and location of diverticula, polyps, and cancers were recorded. Histologically, polyps were classified as adenoma (with low or high dysplasia), hyperplastic, or inflammatory. The relative risk of the association of polyps and cancer with diverticula was assessed. Multiple logistic regression analyses, including age, sex, family history for colorectal cancer (CRC), and family history for diverticula, were carried out. Results: During the study period, 1490 patients were enrolled; 37.2% ( n = 555) showed colonic diverticula or polyps or CRC (308 males, mean age 66 years). Particularly, 12.3% ( n = 183) patients presented only diverticula, 13.7% ( n = 204) only polyps or cancer, 11.3% ( n = 168) both diseases, and 62.7% ( n = 935) neither diverticula nor polyps and cancer. A total of 38 patients presented colorectal cancer, 17 of which had also diverticula. A significant increase in relative risk (RR 2.81, 95% CI 2.27-3.47, p < 0.0001) of colorectal adenoma and cancer in patients with colonic diverticula was found. At multivariate analysis, only diverticula resulted to be significantly associated with colorectal adenomas and cancer (Odds Ratio, OR 3.86, 95% CI 2.90-5.14, p < 0.0001). Conclusions: A significant association of colonic diverticula with colorectal adenoma or cancer was found. This implies that patients with colonic diverticula require a vigilant follow-up procedure for the prevention of colorectal cancer from those applicable to the general population.

Background: Alzheimer's disease (AD) may be a vascular disorder with neurodegenerative consequences opening possibility of preventing AD by targeting vascular risk factors including homocysteine., Objective: The study aims were to assess homocysteine distribution in different forms and severity of cognitive impairment (CogI) [mild cognitive impairment (MCI), probable AD (Prob-AD), possible AD (Poss-AD), and vascular dementia (VaD)] and in NoCogI, and to estimate possible association between hyperhomocysteinemia levels with functional deficit severity and psychobehavioral complications., Methods: In total, 929 (M = 366, F = 563; mean age of 72.55±6.24 years) patients were evaluated with cognitive, neuropsychiatric, affective, and functional assessment scales. Homocysteine serum was set on two levels: between 0 and 10μmol/L and > 10μmol/L. For each patient, blood concentration of folate, vitamin B12, hemoglobin, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), cholesterol, triglycerides, and glycemia were measured., Results: CogI patients demonstrated significantly a higher frequency of homocysteine > 10 (p = 0.003), than NoCogI patients. Patients with moderate and severe dementia had a higher frequency of homocysteine > 10 (p < 0.0001), than MCI and mild dementia. Poss-AD and VaD had a higher frequency of homocysteine > 10 (p = 0.003), than Prob-AD patients. Homocysteine > 10 frequency is directly proportional to increased neuropsychiatric symptom severity (p < 0.0001), and functional impairment severity respectively for ADL (p < 0.0001) and IADL (p < 0.0001)., Conclusion: Higher homocysteine level seems to be significantly related to cognitive impairment frequency and severity, possible AD and VaD, neuropsychiatric symptom severity, and functional impairment severity.

We provide a dataset of 3D coordinate time series of 37 continuous GNSS stations installed for stability monitoring purposes on onshore and offshore industrial settlements along a NW-SE-oriented and ~100-km-wide belt encompassing the eastern Italian coast and the Adriatic Sea. The dataset results from the analysis performed by using different geodetic software (Bernese, GAMIT/GLOBK and GIPSY) and consists of six raw position time series solutions, referred to IGb08 and IGS14 reference frames. Time series analyses and comparisons evidence that the different solutions are consistent between them, despite the use of different software, models, strategy processing and frame realizations. We observe that the offshore stations are subject to significant seasonal oscillations probably due to seasonal environmental loads, seasonal temperature-induced platform deformation and hydrostatic pressure variations. Many stations are characterized by non-linear time series, suggesting a complex interplay between regional (long-term tectonic stress) and local sources of deformation (e.g. reservoirs depletion, sediment compaction). Computed raw time series, logs files, phasor diagrams and time series comparison plots are distributed via PANGAEA ( https://www.pangaea.de ).

Hydrocarbon seepage is overlooked in the marine environment, mostly due to the lack of high-resolution exploration data. This contribution is about the set-up of a relocatable and cost-effective monitoring system, which was tested on two seepages in the Central Adriatic Sea. The two case studies are an oil spill at a water depth of 10 m and scattered biogenic methane seeps at a water depth of 84 m. Gas plumes in the water column were detected with a multibeam system, tightened to sub-seafloor seismic reflection data. Dissolved benthic fluxes of nutrients, metals and Dissolved Inorganic Carbon (DIC) were measured by in situ deployment of a benthic chamber, which was used also for the first time to collect water samples for hydrocarbons characterization. In addition, the concentration of polycyclic aromatic hydrocarbons, as well as major and trace elements were analyzed to provide an estimate of hydrocarbon contamination in the surrounding sediment and to make further inferences on the petroleum system.

Background: Insomnia seems to be related to disability, risk of injury, metabolic syndrome, risk for cardiovascular diseases, cognitive impairment, depression and impaired quality of life. Objectives: The goals in this paper was (1) to keep track of technological concepts and approaches to improve insomnia in elderly people, and (2) to define the effect that information and communication technologies (ICT) is having on patients' care. Design: A systematic review was conducted from existing literature. Our selection criteria included: (1) age ≥ 60 years; (2) diagnosis of insomnia with the International Classification of Sleep Disorders (ICSD-II), (3) CBTi (cognitive behavioural therapy insomnia), (4) use of technological tools, and (5) associations between insomnia-related variables and indices of disability, quality of life, and global clinical assessments. Data analysis: 11 articles were included. An inductive content analysis was used for data extraction. Results: Our review revealed any technological systems that could purportedly rehabilitate elderly patients with insomnia. Three categories of research were identified from the review: (1) Internet Deliver-CBTi, (2) virtual coaches, and (3) sleep technologies. Conclusions: The potential for ICT to support insomnia care at home can improve the quality of life for families and reduce health care costs and premature institutional care.

Background and Study Aims: Functional dyspepsia is an exclusion diagnosis requiring different tests, including endoscopy, often repeated over time. Duodenal biopsies are frequently resorted to, not rarely revealing duodenal microscopic inflammation. Aim of the study is to confirm a previously supposed role of antro-duodenal low-grade inflammation in functional dyspepsia, evaluating the frequency of duodenal lymphocytosis, H. pylori infection and their association in a group of patients with functional dyspepsia compared to asymptomatic control subjects., Patients and Methods: A cross-sectional, observational study has been conducted screening all the patients who underwent duodenal biopsies during upper endoscopy, in a 30 months period. All the patients without endoscopic lesions were analysed. The study group consisted of patients compatible with the diagnosis of functional dyspepsia (Rome III criteria). The control group consisted of healthy asymptomatic subjects in the population subjected to endoscopy. The presence of duodenal lymphocytosis and of H. pylori infection in the two groups was evaluated., Results: 216 patients were enrolled: 161 in the functional dyspepsia group and 55 as asymptomatic control group. The frequency of duodenal lymphocytosis was similar between cases and control groups (25.47% vs 25.45%; p = 0.99), as well as H. pylori infection (26.71% vs 23.64%; p = 0.78). Duodenal lymphocytosis was significantly associated with functional dyspepsia only in H. pylori positive dyspeptic patients (p = 0.047). 94% of the subjects with both lymphocytosis and H. pylori infection suffer from dyspepsia. Duodenal intraepithelial lymphocytosis is significantly associated with bloating (p = 0.0082)., Conclusions: In our cohort of dyspeptic patients, duodenal lymphocytosis is significantly associated with bloating and the simultaneous presence of duodenal lymphocytosis and H. pylori infection is significantly more prevalent than in control subjects., (Copyright © 2019 Pan-Arab Association of Gastroenterology.

Background: Although it is known that Alzheimer's disease (AD) is associated with the progressive accumulation of amyloid β-peptide (Aβ) in the human brain, its pathogenic role has to be completely clarified. Aβ moves from the bloodbrain barrier to the plasma and an increased Aβ production in brain could be associated with higher Aβ concentrations in blood. A recent study has evaluated Aβ40 and Aβ42 levels in human red blood cells (RBCs) with evidence of agedependent higher Aβ concentration in RBCs., Objective: The aim of the study was to investigate if erythrocyte associated Aβ (iAβ) levels could be different in subjects affected by dementia in comparison with controls and according to the patient's cognitive impairment or different dementia subtypes., Method: To answer these questions we assessed iAβ40 and iAβ42 levels in 116 patients: 32 healthy controls, 39 with diagnosis of vascular dementia (VaD), 14 mild cognitive impairment (MCI) and 31 AD., Results: In this population we found significant differences in iAβ42 between controls and cognitive impaired patients. Moreover, iAβ42 significantly differed between dementia vs MCI. AD also showed different iAβ42 levels as compared to VaD. Conversely, no differences were found for iAβ40. All the analyses were adjusted for potential confounders like age, gender and Hb concentration. A direct correlation between increasing iAβ42 concentration and the progression of the cognitive decline using the MMSE score as continuous variable was also found., Conclusion: Our findings support the evidence that iAβ42 could be an instrument to early recognize dementia and predict cognitive impairment., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

Background/aim: The aim of the study was to evaluate the prognostic power of late-life depression (LLD) compared with amnestic mild cognitive impairment (aMCI) for the onset of Alzheimer's disease (AD) within 4 years of follow-up., Methods: We estimated the incidence of AD in 60 patients presenting with aMCI, 115 patients suffering of LLD treated with antidepressants with good compliance, and 66 healthy control (HC) patients, followed for 4 years., Results: The risk to develop AD, within 4 years, was 68.33% for aMCI and 49.57% for LLD. In AD patients 5.60% deteriorated without depression, and 72.20% deteriorated with depression after 4 years of follow-up (p < 0.0001). No HC patients deteriorated to AD or any other dementia type., Conclusion: In our results, aMCI was the first predictive condition that increased the risk to develop AD. Depression is a potentially preventable medical condition across the lifespan and may be a modifiable risk factor., (© 2018 S. Karger AG, Basel.)

Background: Chronic diarrhoea affects 5-10% of the adult population. Histologic lesions of possible diagnostic significance are found under normal colonoscopy in approximately 30% of patients affected by chronic diarrhoea. Mastocytic enterocolitis is characterized by an increase in the number of mucosal mast cells (MC) in the gut of patients with chronic intractable diarrhoea, detected by immunohistochemical staining, responding to mast-cell targeted drugs. The question arises whether to search for MC infiltration in specific subsets of patients as a matter of routine clinical practice., Summary: A systematic electronic search of the English literature up to December 2017 was performed, using Medline, EMBASE, Web of Science, Scopus, and the Cochrane Library. This revealed 9 studies reporting an increased number of MC in the gut mucosa of patients with chronic diarrhoea. No consensus was found, however, on the actual cutoff point, the overlap in range between patients and controls being too great to be of clinical significance. The available evidence does not therefore justify the routine evaluation of MC count. Key Messages: More studies are needed to better define MC count and the significance of MC degranulation in normal and pathological settings. Until these become available, the search for MC infiltration in specific subsets of patients should be restricted to research settings., (© 2018 S. Karger AG, Basel.)

Background: Celiac disease (CD) often manifests with dyspeptic symptoms and chronic gastritis is a common finding., Aim: To evaluate the frequency of lymphocytic gastritis (LG), chronic active gastritis (CAG), and chronic inactive gastritis (CIG) in patients with CD, before and after gluten-free diet (GFD)., Methods: A five-year prospective study including all consecutive patients with a new diagnosis of CD was conducted. Gastric and duodenal biopsy specimens taken both at the time of the CD diagnosis and at the first endoscopic control after 18-24 months on GFD were evaluated., Results: 213 patients with CD were enrolled. At the time of the diagnosis, 42 patients (19.7%) showed normal gastric mucosa, 34 (15.9%) LG, 67 (31.5%) CAG, and 70 (32.9%) CIG. Out of the 34 patients with LG, all were Helicobacter pylori negative and the majority of them showed an improvement both of gastritis (94.1%) and duodenal lesions (82.3%) after GFD. GFD did not show significant effects on CAG and CIG., Conclusions: LG is present in 16% of CD patients, it is not associated with H. pylori infection, and it improves after GFD. Both CAG and CIG are also frequently associated with CD, but fail to respond to a GFD.

ABSTARCT Genome-wide association studies pinpointed common variants in or near the MTNR1B gene encoding MT2 melatonin receptor to be strongly associated with fasting glucose levels. IRS2 gene polymorphisms impact insulin resistance and epicardial fat (EF) thickness, which in turn is correlated with visceral adiposity, cognitive ability and risk for metabolic plus cardiovascular disease. We aimed to discover the interactions between MTNR1B and IRS2 gene polymorphisms, insulin sensitivity, EF thickness and cognitive performance in the elderly. In 60 subjects aged 60 years and older, we evaluated five single nucleotide polymorphisms (SNPs) within the MTNR1B locus (rs10830962, rs4753426, rs12804291, rs10830963, rs3781638), the Gly1057Asp variant of IRS2 gene (rs1805097), biochemical parameters, cognitive performance by the Mini Mental State Examination (MMSE) and EF thickness by transthoracic echocardiography. We found that MTNR1B and IRS2 gene variants impacted EF thickness, lipid profile and glucose homeostasis. IRS2 but not MTNR1B variants impacted MMSE scores. In conclusion, MTNR1B SNPs interact with IRS2 gene variant, correlate with the amount of epicardial adipose tissue and impact glucose homeostasis and lipid profile influencing cardiometabolic risk.

The definition of personalized treatments in tumor disease could lead to an improvement of the therapeutic success rate. Therefore, biomarkers are urgently required in order to select the patients that could benefit from adjuvant therapies in the initial phase of the disease and to better define and treat the clinical/therapeutic subgroups in the advanced pathological phases. Disregulation of cytokine physiological network is directly involved in the genesis and progression of tumors. Cytokines are of central importance in the regulation of immune system, but they are rarely released singly: each cytokine is able to induce the production of many other factors leading to a network in which they cooperate with other cell regulators such as hormones and neuropeptides. For these reasons the research must be directed to the evaluation of the interrelationships between the different cytokines and their respective pathways, as well as their contribution to the disease aetiology and progression in order to identify real and effective drug targets and biomarkers. The T CD4+ helper cells (Th) have various subpopulations, among which Th1, Th2, Th3, Th9 and Th17, respectively produce cytokines. It has become clear that disorders within the interactions of the network of these cytokines can produce neoplastic diseases. Furthermore, studies focusing on gender have shown that the homeostasis of the immune system is controlled by pathways of cytokines that are different between sexes and defined for this reason "genderspecifics". Therefore, this perspective article aims to highlight the significance of these cytokine pathways in order to identify new clinical strategies and personalized therapy in neoplastic diseases., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

At present, very few data are available on deferasirox (DFX) in the treatment of patients with Philadelphia-negative myeloproliferative neoplasms in fibrotic phase (FP-MPN) and transfusion dependence. To address this issue, a retrospective analysis of 28 patients (22 male and 6 female) with FP-MPN and iron overload secondary to transfusion dependence was performed, based on patients enrolled in the database of our regional cooperative group who received treatment with DFX. DFX was started after a median interval from diagnosis of 12.8 months (IR 7.1-43.1) with median ferritin values of 1415 ng/mL (IR 1168-1768). Extra-hematological toxicity was reported in 16 of 28 patients (57.1%), but only two patients discontinued treatment due to toxicity. Among 26 patients evaluable for response (≥6 months of treatment), after a median treatment period of 15.4 months (IR 8.1-22.3), 11 patients (42.3%) achieved a stable and consistent reduction in ferritin levels <1000 ng/mL. As for hematological improvement, 6 of 26 patients (23%) showed a persistent (>3 months) rise of Hb levels >1.5 g/dL, with disappearance of transfusion dependence in four cases. Treatment with DFX is feasible and effective in FP-MPN with iron overload. Moreover, in this setting, an erythroid response can occur in a significant proportion of patients., (© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: To characterize the differences of caregiver burden in patients with Alzheimer's disease (AD) and vascular dementia (VaD) in order to improve the care counselling and management plan., Methods: We included 506 patients consecutively attending the Alzheimer's Evaluation Unit of a Geriatric Unit, evaluated with Mini Mental State Examination (MMSE), Clinical Dementia Rating (CDR), Hamilton Rating Scale for Depression, and Neuropsychiatric Inventory. To all caregivers were administered the Caregiver Burden Inventory (CBI), a 24-item multidimensional questionnaire in which 5 subscales explore 5 dimensions of caregiver burden: (1) CBI-Objective; (2) CBI-Developmental; (3) CBI-Physical; (4) CBI-Social; and (5) CBI-Emotional., Results: The present study included, respectively, 253 AD patients and 253 VaD patients. AD patients at baseline showed a significantly higher instruction level (p < .0001), higher grade of cognitive impairment (MMSE, p < .0001), and increased severity stage of dementia (CDR, p < .0001) than VaD patients. AD caregivers, mainly females (p = 0.010), devoted significantly more length of time care (in months, p = 0.010) and time of daily care (in hours, p = 0.011) and showed a significantly higher burden level in CBI-Objective (p = 0.047), CBI-Physical (p < .0001), CBI-Social (p = 0.003), CBI-Emotional (p < .0001), and CBI-total score (p < .0001), than VaD caregivers. In both caregiver groups, a higher presence of spouses and sons (p < .0001) compared to other relatives was observed. AD caregiver burden showed a significant association with sex of caregivers and length of time care in months., Conclusions: AD caregivers showed a higher burden level than VaD caregivers, and this appeared to be associated with sex and length of time care., (Copyright © 2014 John Wiley & Sons, Ltd.)

Objective: To evaluate in a pilot single-blind randomized controlled clinical trial the efficacy of an integrated treatment with rivastigmine transdermal patch (RTP) and cognitive stimulation (CS) in Alzheimer's disease (AD) patients at 6-month follow-up., Methods: We enrolled 90 patients with an age ≥65 years admitted to the outpatient Alzheimer's Evaluation Unit with diagnosis of AD. Patients were randomized to enter in the Group-1 (RTP + CS) or in the Group-2 (RTP). All patients at baseline and after 6 months were evaluated with the following tools: Mini Mental State Examination (MMSE), Clinical Dementia Rating (CDR), Hamilton Rating Scale for Depression (HAM-D), Geriatric Depression Scale (GDS-15), Neuropsychiatric Inventory (NPI), Neuropsychiatric Inventory-Distress (NPI-D), and a standardized Comprehensive Geriatric Assessment, including also activities of daily living (ADL), instrumental activities of daily living (IADL), and the Mini Nutritional Assessment (MNA). Mortality risk was assessed using the Multidimensional Prognostic Index (MPI)., Results: At baseline no significant difference was shown between the two groups. After 6 months of follow-up, there were significant differences between Group-1 and Group-2 in: MMSE: +6.39% vs. +2.69%, CDR: +6.92% vs. +1.54%, HDRS-D = -60.7% vs. -45.8%, GDS: -60.9% vs. -7.3%, NPI: -55.2% vs. -32.7%%, NPI-D: -55.1% vs. -18.6%, ADL: +13.88% vs. +5.95%, IADL: +67.59% vs. +18.28%, MNA: +12.02% vs. +5.91%, and MPI: -29.03% vs. -12.90%., Conclusion: The integrated treatment of RTP with CS in AD patients for 6 months improved significantly cognition, depressive and neuropsychiatric symptoms, functional status, and mortality risk in comparison with a group of AD patients receiving only RTP., (Copyright © 2014 John Wiley & Sons, Ltd.)

To highlight the role of azacytidine (AZA) in patients with myeloproliferative neoplasms developing blast phase (MPN-BP), we evaluated retrospectively 19 patients [M/F 15/4, median age 71.3 years, interquartile range (IQR) 64.5-77.7] reported in the database of our cooperative group. Median time from diagnosis to BP evolution was 52.7 months (IQR 11.2-181.8). All patients were treated with AZA at the standard dosage of 75 mg/m(2). Two patients died early after 5-AZA initiation from pulmonary fungal infection and respiratory failure respectively, 4 patients had a disease progression, 4 patients a stable disease, 3 patients had an hematological improvement, 1 patient a partial response and 5 pts (26.3%) a complete response (CR) after 4, 4, 4, 5, and 12 months. The median cumulative survival from BP evolution was 9.9 months (95%CI 6.6-13.1): the comparison with an historical cohort of 72 patients with MPN-BP treated with approaches other than AZA (median cumulative survival 3.1 months, 95%CI 1.1-5.0) showed a significant advantage for patients treated with AZA (p=0.02). Our data confirm the relative efficacy and safety of AZA in this group of patients with otherwise dismal prognosis, underlining the possible achievement of long-lasting responses in a sizeable portion of them., (Copyright © 2015 Elsevier Ltd.

Background: Non-celiac gluten sensitivity (NCGS) is a recently recognized disorder, characterized by the occurrence of symptoms following gluten ingestion. It is often self-diagnosed by the patient, but should be confirmed by the response to a gluten-free diet, followed by a gluten challenge. Celiac disease (CD) and wheat allergy (WA) must first be ruled out., Aims: (1) to determine the frequency of visits performed for symptoms self-perceived as gluten-related; (2) to assess in this cohort, the proportion of patients satisfying the diagnostic criteria for NCGS., Methods: A two-year prospective study including all consecutive patients complaining of gluten-related symptoms. NCGS was diagnosed on the basis of the disappearance of the symptoms within 6 months of a gluten-free diet, followed by their reappearance with the reintroduction of gluten in the diet for 1 month., Results: Three hundred and ninety two patients complaining of gluten-related symptoms were enrolled; 26 of these (6.63%) were affected by CD, 2 (0.51%) by WA and 27 were diagnosed with NCGS (6.88%). The remaining 337 patients (85.96%) did not experience any change of symptoms with a gluten-free diet. The PPV of the gluten-related symptom was found to be 7%., Conclusion: Eighty six percent of patients reporting gluten-related symptoms have neither NCGS, nor CD, nor WA. Self-perceived gluten-related symptoms are rarely indicative of the presence of NCGS., (© 2015 S. Karger AG, Basel.)

The amount of fat surrounding the heart, called epicardial adipose tissue (EAT), is a marker of cardiometabolic risk and correlates with the quantity of visceral adipose tissue (VAT). The amount of VAT is associated with an increased risk of cardiovascular and cerebrovascular disease and with cognitive impairment. We aimed to evaluate the association between EAT thickness as a measure of VAT and cognitive function. In 71 elderly subjects (mean age 72.7 ± 7.1 yr) we measured EAT thickness through transthoracic echocardiography, assessed the metabolic profile through evaluation of biochemical parameters, and estimated the cognitive function via the Mini Mental State Examination (MMSE). We found that greater EAT thickness was associated with lower cognitive performance evaluated by MMSE (P < 0.01) independently of the presence or absence of metabolic syndrome or obesity. Lower MMSE results were also associated with the presence of metabolic syndrome (P < 0.01), elevated HOMA index (P < 0.01), and high BMI values (P < 0.01). The results of mediation analysis confirmed that the total effect of metabolic syndrome, HOMA, and BMI on MMSE is mainly explained by an indirect effect through EAT thickness. In conclusion, increased EAT thickness assessed by transthoracic echocardiography is associated with deficient results of psychometric tests assessing cognitive performance and may consistently foresee impairment of cognition in the elderly.

Studies focusing on gender have shown that differences exist in how the immune system responds to disease and therapy. Understanding how gender influences immunological mechanisms in health and disease and identifying gender-specific biomarkers could lead to specifically tailored treatment and ultimately improve therapeutic success rates. T helper1 (Th1) and Th2 cytokines (Th1/Th2) have pivotal roles in the homeostasis of Th1 and Th2 cell network functions in the immune response but sex steroids affect Th1/Th2 production in different ways and a natural sexual dimorphism in the immune response has been shown. In order to investigate these differences further, we developed Th-cytokine data-driven models of the immune response and evaluated healthy subject peripheral blood samples. Independent cohorts of colorectal cancer and adenoma patients were also studied for comparison purposes. Our results show that the interferon (IFN)γ production pathway for immune response homeostasis is specific to men whilst the interleukin- (IL-) 6 production pathway for immune response homeostasis is specific to women. The IL-10 pathway for restoring immune system resting homeostasis was common to both but was controlled by the respective gender-specific pathways. These gender pathways could well be used as targets and biomarkers in translational research into developing new clinical strategies.

Purpose: Promising new therapeutic options for follicular lymphoma (FL) include fludarabine plus mitoxantrone (FM) and the mouse/human anti-CD20 antibody, rituximab. We performed a randomized comparative trial of FM with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) front-line chemotherapy with and without sequential rituximab., Patients and Methods: All previously untreated CD20(+) FL patients presenting in 15 Italian cooperative institutions from October 1999 were randomly allocated to FM or CHOP. Following clinical or molecular restaging, patients in complete remission (CR) with bcl-2/IgH negativity (CR(-)) received no further treatment; those in CR with bcl-2/IgH positivity (CR(+)) received rituximab, as did those in partial remission (PR) with bcl-2/IgH negativity (PR(-)) or positivity (PR(+)); nonresponders (NR subgroup) were off study., Results: After chemotherapy, the FM arm achieved higher rates of CR (68% [49 of 72 patients] v 42% [29 of 68 patients]; P =.003) and CR(-) (39% [28 of 72 patients] v 13 of 68 patients [19%]; P =.001). Rituximab elicited CR(-) in 55 of 95 treated patients (58%). The final CR(-) rate was higher in the FM arm (71% [51 of 72 patients] v 51% [35 of 68 patients]; P =.01). However, with a median follow-up of 19 months (range, 9 to 37 months), no statistically significant difference was found among the various study arms in terms of both progression-free (PFS) and overall survival (OS)., Conclusion: These results indicate that FM is superior to CHOP for front-line treatment of FL and that rituximab is an effective sequential treatment option. However, they also confirm that this superiority is unlikely to translate into either better PFS or OS.

Purpose: A first comparative trial of fludarabine (FLU) alone versus FLU plus idarubicin (FLU-ID) for indolent or mantle-cell lymphomas., Patients and Methods: From September 1995 to July 1998, 199 patients aged 25 to 65 years (median, 54 years) with newly diagnosed stages II to IV indolent or mantle-cell lymphomas (standard risk according to the International Prognostic Index) were enrolled onto a multicenter, 1:1 randomized study. Of the 199 patients who were able to be assessed, 101 were assigned to the FLU group (six monthly cycles of FLU 25 mg/m(2)/d on days 1 through 5) and 98 to the FLU-ID group (six monthly cycles of FLU 25 mg/m(2)/d on days 1 through 3 and idarubicin 12 mg/m(2) on day 1)., Results: In the FLU group, complete response (CR) and partial response rates were 47% and 37%, respectively, whereas in the FLU-ID group, they were 39% and 42%, respectively. In-depth analysis of the CR rate with respect to histologic type showed that FLU seemed to be superior to FLU-ID in treating follicular lymphomas (60% v 40%, respectively), whereas FLU-ID seemed to be more effective than FLU in treating nonfollicular lymphomas (small lymphocytic, 43% v 29%, respectively; immunocytoma, 38% v 23%, respectively; P = not significant), excluding the mantle-cell subset (in which there was no difference between the two groups). No striking differences were observed between the two protocols in terms of overall response or toxicity, which was generally mild. However, with a median follow-up of 19 months, only 29 patients (62%) who received FLU alone have maintained their initial CR, compared with 32 (84%) of those who received FLU-ID therapy (P =.021)., Conclusion: Although the FLU-ID regimen may not significantly improve the induction of CR in most indolent-lymphoma patients, our preliminary data do suggest that, with respect to FLU alone, it may be capable of conferring a longer-lasting CR and that it might be superior in terms of CR rate in small lymphocytic and immunocytoma subtypes.

In a groups of 254 patients treated for Hodgkin's disease with a follow up period of minimum 2 years, 3 cases of acute non lymphoid leukaemia (ANLL) were observed: erythroleukaemia, myelomonocytic and myeloblastic leukaemia, respectively. The crude incidence of leukaemia in all patients was 0.0128 and patient year risk was estimated to be 0.003652. All 3 patients had received radiation therapy and chemotherapy. In all cases of haemopoietic dysplasia preceded ANLL. Bone marrow chromosome investigations showed an abnormal karyotype in all patients: chromosomal changes were present in 100% of cells and revealed a non-random distribution, the most frequent involvement being clustered to chromosomes nos 11, 17 and 21. Hypodiploidy was prevalent and multiple structural rearrangements, such as markers, rings and minutes, were present in a high percentage of cells. Other changes involved chromosomes nos 5, 7 and 14. Our results are compared with other previously reported cases and possible pathogenetic implications are discussed.

51Cr-platelet kinetics study was performed in 197 patients with chronic ITP after corticosteroid therapy had failed to induce a long lasting remission. The incidence of splenic, spleno-hepatic, hepatic and diffuse platelet sequestration site was 58%, 17%, 6% and 19%, respectively. Splenic and spleno-hepatic sequestration sites were more frequent in patients less than 30 years old and in patients with a platelet count lower than 50 x 10(9)/1. 111 patients were splenectomized shortly after the study. Normalization of the platelet count was obtained more frequently in patients with splenic and spleno-hepatic sequestration than in the others. Labelled platelet sequestration site was the best predictor of the outcome of splenectomy. Platelet kinetics is a non-invasive investigation that should be performed early after the diagnosis of chronic ITP in all patients eligible for splenectomy.
