Mapping Gilles de la Tourette syndrome through the distress and relief associated with tic-related behaviors: an fMRI study.

Personal distress associated with tic urges or inhibition and relief associated with tic production are defining features of the personal experience in Gilles de la Tourette syndrome (GTS). These affective phenomena have not been studied using fMRI, hindering our understanding of GTS pathophysiology and possible treatments. Here, we present a novel cross-sectional fMRI study designed to map tic-related phenomenology using distress and relief as predicting variables.

When action prediction grows old: An fMRI study.

Predicting the unfolding of others' actions (action prediction) is crucial for successfully navigating the social world and interacting efficiently. Age-related changes in this domain have remained largely unexplored, especially for predictions regarding simple gestures and independent of contextual information or motor expertise. Here, we evaluated whether healthy aging impacts the neurophysiological processes recruited to anticipate, from the observation of implied-motion postures, the correct conclusion of simple grasping and pointing actions.

Sense of agency disturbances in movement disorders: A comprehensive review.

Sense of agency refers to the experience that one's self-generated action causes an event in the external environment. Here, we review the behavioural and brain evidence of aberrant experiences of agency in movement disorders, clinical conditions characterized by either a paucity or an excess of movements unrelated to the patient's intention. We show that specific abnormal agency experiences characterize several movement disorders.

Neoadjuvant Treatment for Pancreatic Adenocarcinoma: A False Promise or an Opportunity to Improve Outcome?

Pancreatic ductal adenocarcinoma (PDAC) has an aggressive tumor biology and is associated with poor survival outcomes. Most patients present with metastatic or locally advanced disease. In the 10-20% of patients with upfront resectable disease, surgery offers the only chance of cure, with the addition of adjuvant chemotherapy representing an established standard of care for improving outcomes.

Better survival of patients with oligo- compared with polymetastatic cancers: a systematic review and meta-analysis of 173 studies.

: The modern concept of oligometastatic (OM) state has been initially developed to describe patients with a low burden of disease and with a potential for cure with local ablative treatments. We systematically assessed the risk of death and relapse of oligometastatic (OM) cancers compared to cancers with more diffuse metastatic spread, through a meta-analysis of published data.  : PubMed, the Cochrane Library, and EMBASE were searched for studies reporting prognosis of patients with OM solid tumors.

Altered sense of agency in Gilles de la Tourette syndrome: behavioural, clinical and functional magnetic resonance imaging findings.

Current neurocognitive models of motor control postulate that accurate action monitoring is crucial for a normal experience of agency-the ability to attribute the authorship of our actions and their consequences to ourselves. Recent studies demonstrated that action monitoring is impaired in Gilles de la Tourette syndrome, a movement disorder characterized by motor and vocal tics. It follows that Tourette syndrome patients may suffer from a perturbed sense of agency, the hypothesis tested in this study.

Predicting the Sensory Consequences of Self-Generated Actions: Pre-Supplementary Motor Area as Supra-Modal Hub in the Sense of Agency Experience.

Sense of agency refers to the feeling that one's self-generated action caused an external environment event. In a previous study, we suggested that the supplementary motor area (SMA), in its anterior portion (pre-SMA), is a key structure for attributing the sense of agency for the visual consequences of self-generated movements. However, real-life actions can lead to outcomes in different sensory modalities, raising the question of whether SMA represents a supra-modal hub for the sense of agency.

How the effects of actions become our own.

Every day, we do things that cause effects in the outside world with little doubt about who caused what. To some, this sense of agency derives from a post hoc reconstruction of a likely causal relationship between an event and our preceding movements; others propose that the sense of agency originates from prospective comparisons of motor programs and their effects. Using functional magnetic resonance imaging, we found that the sense of agency is associated with a brain network including the pre-supplementary motor area (SMA) and dorsal parietal cortex.

Eyes wide shut: How visual cues affect brain patterns of simulated gait.

In the last 20 years, motor imagery (MI) has been extensively used to train motor abilities in sport and in rehabilitation. However, MI procedures are not all alike as much as their potential beneficiaries. Here we assessed whether the addition of visual cues could make MI performance more comparable with explicit motor performance in gait tasks.

Motor imagery training speeds up gait recovery and decreases the risk of falls in patients submitted to total knee arthroplasty.

With Motor imagery (MI), movements are mentally rehearsed without overt actions; this procedure has been adopted in motor rehabilitation, primarily in brain-damaged patients. Here we rather tested the clinical potentials of MI in purely orthopaedic patients who, by definition, should maximally benefit of mental exercises because of their intact brain. To this end we studied the recovery of gait after total knee arthroplasty and evaluated whether MI combined with physiotherapy could speed up the recovery of gait and even limit the occurrence of future falls.

Predictive Accuracy of Electrocardiographic Monitoring of Patients With Syncope in the Emergency Department: The SyMoNE Multicenter Study.

Background: Arrhythmia is one of the most worrisome causes of syncope. Electrocardiographic (ECG) monitoring is crucial for the management of non-low-risk patients in the emergency department (ED). However, its diagnostic accuracy and optimal duration are unknown.

Neurofunctional correlates of body-ownership and sense of agency: A meta-analytical account of self-consciousness.

Self-consciousness consists of several dissociable experiences, including the sense of ownership of one's body and the sense of agency over one's action consequences. The relationship between body-ownership and the sense of agency has been described by different neurocognitive models, each providing specific neurofunctional predictions. According to an "additive" model, the sense of agency entails body-ownership, while an alternative "independence" hypothesis suggests that they represent two qualitatively different processes, underpinned by distinct brain systems.

Risk of second primary tumors in GIST survivors: A systematic review and meta-analysis.

Introduction: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors arising in the gastrointestinal tract. Second primary tumors (SPTs) have been reported frequently, either synchronously or during follow-up, in patients diagnosed with GISTs.

Methods: We carried out an electronic search of PubMed, SCOPUS, Web of Science, EMBASE, and the Cochrane Library seeking articles investigating the incidence of SPTs in patients with concomitant GIST.

The Brain in (Willed) Action: A Meta-Analytical Comparison of Imaging Studies on Motor Intentionality and Sense of Agency.

Voluntary actions can be fractionated in different phenomena: from the emergence of intentions and the ensuing motor plans and actions, to the anticipation and monitoring of their outcomes, to the appreciation of their congruency with intentions and to the eventual emergence of a sense of agency. It follows that motor intention and the sense of agency should occur at different stages in the normal generation of willed actions. Both these processes have been associated with a fronto-parietal motor network, but no study has investigated to what extent the two experiences can be dissociated for the brain regions involved.

Adjuvant radiotherapy for Merkel cell carcinoma: A systematic review and meta-analysis.

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy with a high propensity for local recurrence and regional and distant metastases. The main treatment is surgery with narrow excision margins and draining nodes, plus or minus adjuvant radiotherapy (RT) on the surgical bed and/or lymph nodes. We performed a systematic review and meta-analysis of the benefits of adjuvant RT in MCC treatment.

Prognostic and predictive role of elevated lactate dehydrogenase in patients with melanoma treated with immunotherapy and BRAF inhibitors: a systematic review and meta-analysis.

Levels of serum lactate dehydrogenase (LDH) are a recognized prognostic factor in malignant melanoma (MM). It is relevant to confirm its prognostic role in patients treated with targeted therapies [BRAF inhibitors (BRAFi) and MEK inhibitors (MEKi)] and immunotherapy (IT). Furthermore, its role as a predictive marker in patients treated with these drugs had still not been investigated.

Dissecting the neurofunctional bases of intentional action.

Here we challenge and present evidence that expands the , , and anatomical model of intentional action, which states that internally driven decisions about the content and timing of our actions and about whether to act at all depend on separable neural systems, anatomically segregated along the medial wall of the frontal lobe. In our fMRI event-related paradigm, subjects acted following conditional cues or following their intentions. The content of the actions, their timing, or their very occurrence were the variables investigated, together with the modulating factor of intentionality.

Adjuvant chemotherapy for resected biliary tract cancers: a systematic review and meta-analysis.

Introduction: The use of adjuvant treatment (AT) in resected biliary tract cancers (BTC) is still controversial. No efficacy comparison has been performed between chemotherapy (CT) and chemoradiotherapy (CTRT). A systematic review of the available evidence regarding adjuvant chemotherapy (AC) in resected BTC was performed.

The What, the When, and the Whether of Intentional Action in the Brain: A Meta-Analytical Review.

In their attempt to define discrete subcomponents of intentionality, Brass and Haggard (2008) proposed their (-) which postulates that the content, the timing and the possibility of generating an action can be partially independent both at the cognitive level and at the level of their neural implementation. The original proposal was based on a limited number of studies, which were reviewed with a discursive approach. To assess whether the model stands in front of the more recently published data, we performed a systematic review of the literature with a meta-analytic method based on a hierarchical clustering (HC) algorithm.

TSH-Suppressive Therapy: A Thorny Issue.

Unlabelled: Thyroid stimulating hormone (TSH)-suppressive therapy with levothyroxine is a cornerstone of thyroid carcinoma follow-up therapy, but the achievement of therapeutic goals must be balanced against L-T4 side effects. We describe the case of a 64-year-old cardiopathic patient with papillary thyroid carcinoma and autoimmune thyroiditis, whose cardiac condition worsened during TSH-suppressive therapy. TSH concentrations also fluctuated widely because of changing intestinal absorption due to coeliac disease.

Bone quality in beta-thalassemia intermedia: relationships with bone quantity and endocrine and hematologic variables.

We report the first evaluation of bone quality in 70 thalassemia intermedia (TI) patients (37 males, 33 females, age 41 ± 12 years). Thirty-three patients (47%) had been transfused, 34 (49%) had been splenectomized, 39 (56%) were on iron chelation therapy, and 11 (16%) were on hydroxyurea. Mean hemoglobin was 9.

Role of molecular imaging in the management of patients affected by inflammatory bowel disease: State-of-the-art.

Aim: To present the current state-of-the art of molecular imaging in the management of patients affected by inflammatory bowel disease (IBD).

Methods: A systematic review of the literature was performed in order to find important original articles on the role of molecular imaging in the management of patients affected by IBD. The search was updated until February 2016 and limited to articles in English.

Predictive value of (18)F-FDG PET/CT in restaging patients affected by ovarian carcinoma: a multicentre study.

Purpose: Ovarian cancer is the eighth most common malignancy among women and has a high mortality rate. Prognostic factors able to drive an effective therapy are essential. (18)F-Fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has been investigated in patients with epithelial ovarian cancer and showed promise in diagnosing, staging, detecting recurrent lesions and monitoring treatment response.

Long response to eribulin in breast cancer: a case report.

No definitive cure is available for metastatic breast cancer and current therapies mainly focus on symptom control and minimization of adverse events to extend survival and maintain a good quality of life. Current treatment options include hormonal and chemotherapeutic agents which are characterized by different toxicity profiles and are selected based on patients' performance status and prior therapies. Eribulin is a microtubule dynamic inhibitor which acts by sequestering tubulin molecules into aggregates, thus preventing microtubule growth and causing apoptosis.
