Advanced mapping of inorganic treatments on porous carbonate stones by combined synchrotron radiation high lateral μXRPD and μXRF. Sci Rep 2024; 14:9108.

Abstract
Understanding the effects of consolidating inorganic mineral treatments on carbonate stones of cultural heritage, and on the nature and distribution of newly formed products within the matrix, poses a significant challenge in Heritage Science and Conservation Science. Existing analytical methods often fail to deliver spatial and compositional insights into the newly formed crystalline phases with the appropriate high lateral resolution. In this study, we explore the capabilities and limitations of synchrotron radiation (SR) micro-X-ray powder diffraction (μXRPD) mapping combined with micro-X-ray fluorescence (μXRF) to give insight into compounds formed following the application of ammonium oxalate (AmOx) and diammonium phosphate-based (DAP) solutions on porous carbonate stone. Ultimately, the integration of μXRPD mapping and μXRF analysis proved itself a powerful asset in providing precise qualitative and quantitative data on the newly formed phases, in the case of both calcium oxalates (CaOxs) and calcium phosphates (CaPs), and their complex stratigraphic distribution, thus opening a new route for applications to a more comprehensive study of inorganic treatments applied to carbonate substrates.

Abstract
Abstract
Background
Cardiogenic shock (CS) includes several phenotypes of congestion or hypoperfusion with heterogenous hemodynamic features. Timely prognostication with scoring tools is warranted to identify patients requiring escalation to mechanical circulatory support (MCS) and to avoid futility.
Purpose
Accordingly, we explored the role of the updated Society for Cardiovascular Angiography and Interventions (SCAI) stages classification on in-hospital mortality using a prospective national registry.
Methods
The Altshock-2 Registry includes 237 patients with CS of all etiologies enrolled between March 2020 and February 2022 in 11 Italian Centers. Patients were classified according to the admission SCAI stages (assigned prospectively and independently updated according to the most recently released version); 24-hour re-assessment was prospectively performed in 201 patients. In-hospital mortality was evaluated for association with admission and 24 hours SCAI stages adjusted for the most relevant clinical covariates.
Results
Of the 237 patients included, 20 (8.4%) had SCAI shock stage B, 132 (55.8%) SCAI stage C, 60 (25.3) SCAI stage D and 25 (10.5%) SCAI stage E. Patients in stage B had the worst reclassification at 24-hours, with 42% of them showing worsened status and only 8% improving. In-hospital mortality was 38%. The revised SCAI stages at baseline were not independently associated with in-hospital mortality, whereas the SCAI classification at 24-h correctly and independently predicted mortality (the rate of in-hospital death was 18% for patients in SCAI shock stage B, 27% for SCAI shock stage C, 64% for SCAI shock stage D, 100% for SCAI shock stage E). At the multivariate analysis (adjusted for age, gender, eGFR, inotropic score and MCS) only SCAI classification at 24-hour evaluation was an independent predictor of in-hospital mortality (OR and 95% CI were, respectively, 3.32, 0.36–30.63, p=0.290 for SCAI stage C and 13.07, 1.69–146.3 for SCAI stage D, with E perfectly predicting because all patients died).
Conclusions
The revised SCAI stage classification may improve prognostication only at 24-hour evaluation. Aggressive treatment (either pharmacological or with MCS escalation) should be tailored in order to achieve prompt clinical improvement within the first 24-hours; refractory SCAI stage E at 24 hours portends dismal prognosis.

Abstract
Introduction Many studies have searched for an association between violence and psychiatric diagnoses, without providing a confirmative result. Objectives We have sought to deepen this topic, analysing different aspects of aggressivity, focusing on a specific diagnosis and its particular phases of illness, and looking for a correlation between psychiatric co-diagnoses and outpatients’ visits adherence. Methods We studied 151 bipolar type I inpatients presenting complaint, past medical and family history; we collected information about lifetime hetero/self-aggressive behaviours, irritability, agitation, suicide attempts, alcohol, or substance abuse. Results ![]()
![]()
The overall aggressivity in our sample resulted in 11.92% of cases, while the number of aggressive episodes during euthymia decreased to 2.64%, close to the population without psychiatric disorders. Personality disorders and alcohol abuse appeared to be the main risk factors for irritability [Fig. 1]; substance abuse for both irritability and hetero-aggressive behaviour [Fig. 2]. We observed that subjects who displayed better compliance to follow-up visits exhibited a significant lower aggressive behaviour than less adherent subjects. Moreover, our data disconfirm the common conception that correlates the presence of psychotic features to violence. Conclusions Studying aggressive in a bipolar population, we observed that the rare episodes of aggressiveness were condensed in active phases of illness and mainly related to alcohol or substance abuse, while violent acts during long periods of wellbeing appear in line with those of the general population. We are confident our data might be helpful in deconstructing the stigma that a psychiatric diagnosis equals to violent behaviour. Disclosure No significant relationships.

Abstract
Introduction Esketamine is a novel antidepressant approved by the FDA in 2019 in the form of an intranasal spray, recommended for Treatment-Resistant Depression (TRD). The intranasal spray system appears to be more manageable than intravenous ketamine infusion. It contains ketamine’s S- isomer which is four-fold more potent for the NMDA receptor. Objectives The aim of this case series is to describe our clinical experience in the use of Esketamine. Methods 6 TRD patients (3 men; 3 women) were recruited in San Raffaele Turro Hospital from March 2021. All patients (2 bipolar and 4 unipolar) were diagnosed with a Major Depressive Episode according to DSM-5 criteria, resistant to at least two antidepressants. Initially, Esketamine was administrated twice weekly for one month; afterward, it was administrated once weekly for a month; finally, it was administrated once weekly or every two weeks for a month. Clinical scales (HAM-D, YMRS, SSI, HAM-A, MADRS, CADSS) were administrated to assess symptoms and sides effects before and after each administration on a weekly basis. Results
Three patients out of six showed an improvement in depressive symptoms: two patients had remission (final HAM-D score < 8); one patient had a clinical response (final HAM-D score < 50 % respect baseline value). Three patients withdrew the treatment: two for perceived inefficacy, after 16 and 19 administrations, one for personal reasons. Conclusions The use of Esketamine in our TRD patients showed good effectiveness and tolerability but randomized controlled clinical trials are needed to confirm our findings.

Abstract
Introduction
Treatment-Resistant Depression continues to represent a great challenge for clinicians.
Objectives
We investigated patients with history of resistance, assessing prognostic factors, response to treatments, and remission over time.
Methods
We recruited 202 unipolar and bipolar depressed inpatients. According to anamnestic backgrounds, patients were assigned to: A) Non-resistant
: responders, with no characteristics of resistance in the current episode. B) Resistant: resistant to two antidepressant trials of adequate doses and duration. C) Pseudo-resistant
: non-responders, not classifiable as Resistant because of inadequate trials. During hospitalization, patients were treated by clinical judgment, following a rehabilitation program.

On the day of admission, non-responders were 44.5% of the sample, but 39.3% of them did not meet the Resistant criteria, defining the Pseudo-resistant
group. Pseudo-resistant
differed from others by younger age, fewer illness episodes, higher rate of personality disorders, and different therapies during hospitalization [Fig.1,2,3]. Pseudo-resistant
remission rate, significantly greater than Resistant one, was comparable to Non-resistant
[Tab.1]. *Kruskal-Wallis Test **Chi-Squared Test
Conclusions
This study outlines a new group of depressed patients that, apparently drug-resistant, displays the same outcome as responders when treated with first-line drugs during hospitalization, certainly taking benefit from the psychoeducational program. Quick recognition of these patients could be crucial to giving optimal care.

Abstract
Introduction
Sleep plays a key role in the pathogenesis and clinic of mood disorders. However, few studies have investigated electroencephalographic sleep parameters during the manic phases of Bipolar Disorder (BD).
Objectives
Sleep management is a priority objective in the treatment of the manic phases of BD and the polysomnographic investigation can be a valid tool both in the diagnostic phase and in monitoring clinical progress.
Methods
Twenty-one patients affected by BD, manic phase, were subjected to sleep monitoring via PSG in the acute phase (at the entrance to the ward) and in the resolution phase (near discharge). All participants were also clinically evaluated using Young Manic Rating Scale (YMRS) Pittsburgh Sleep Quality Index (PSQI), Morningness-eveningness Questionnaire (MEQ) at different timepoints.
Results
Over the hospitalization time frame there was an increase in quantity (Total Sleep Time) and an improvement in the quality and effectiveness of sleep (Sleep Efficiency). In addition, from the point of view of the EEG structure, clinical improvement was accompanied by an increase in the percentage of REM sleep.
Conclusions
Sleep monitoring by PSG can be a valuable tool in the clinical setting both in the diagnostic phase, “objectively” ascertaining the amount of sleep, and in the prognostic phase, identifying electroencephalographic characteristics that can predict the patient’s progress and response to drug therapy. The improvement in effectiveness and continuity of sleep and the change in its structure that accompanies the resolution of manic symptoms also testifies how the regularization of the sleep-wake rhythm is to be considered a priority in treating manic phases.

Introduction
Optimal venous access is crucial in successful cardiac device implantation. Most commonly used accesses are subclavian or axillary vein puncture and cephalic vein cutdown. The extrathoracic access has the advantage of reducing the risk of pneumothorax and lead disfunction; thus, this approach is recommended as the first choice approach.
Purpose
The aim of our retrospective registry was to evaluate the incidence of long-term device complications (pneumothorax, lead rupture or displacement, hematoma, infection or bleeding) with different venous approaches in four high-volume centers in Italy.
Methods
We collected data from implantation and device complications during follow up using available electronic records from each center.
Results
We included 4443 patients, mean age 73±11 years. Median follow up was 118 months (IC range 59-198 months). The incidence of any complication was 7.7 %, without difference between intrathoracic and extrathoracic access (7.8% vs 7.7% respectively, p=0.70). However, lead rupture was more frequent in the intrathoracic group (5.3% vs 1.4%, p=0.04).
Conclusion
In experienced, high-volume centers, the use of intrathoracic vein puncture in the case of unsuitable extrathoracic access may represent a safe alternative of venous access in patients undergoing cardiac device implantation, although associated with a higher occurrence of lead rupture.

Background
Myocardial strain assessed with speckle tracking echocardiography is a sensitive marker of cardiac dysfunction, with long-term prognostic value in many cardiac conditions. Both left ventricular global longitudinal strain (LV-GLS) and right ventricular longitudinal strain (RV-LS) were affected by severe SARS-CoV 2 infection but little is known about cardiac involvement in patients with asymptomatic/mild disease that did not require hospitalization.
Aim
To assess if subclinical myocardial dysfunction could be identified using LV-GLS and RV-LS in patients with previous asymptomatic/mild SARS-CoV 2 infection.
Methods
40 young adults patients (70% males, mean age 24.4 ± 8.4 years), who had a confirmed diagnosis of SARS-CoV-2 infection and were asymptomatic or only mildly symptomatic, without previous known comorbidities/cardiovascular risk factors, were retrospectively included. Patients underwent standard transthoracic echocardiogram and speckle tracking echocardiographic study at least 3 months after diagnosis. A total of 44 age, sex, and body surface area comparable healthy subjects were used as control group.
Results
LV-GLS was within normal limits but significantly lower in the cases group compared to controls (-22.7 ± 1.6% vs. -25.7 ± 2.3%; p < 0.001). Left ventricular ejection fraction (63.3 ± 4.1% vs 63.9 ± 4.6%; p = 0.5), tricuspid annular plane systolic excursion (24.3 ± 3.7 vs. 23.7 ± 3.3; p = 0.5) and RV-LS (-23.2 ± 3 vs. -23.6 ± 2.7; p = 0.6) were comparable between the two groups.
Moreover, in the infection group, there were 25 subjects (30.1% vs 9.6% in the control group, p < 0.001) with a regional peak systolic strain of the left ventricle below -16% in at least two segments. At multivariable logistic regression corrected for age, gender and body surface area, previous SARS-CoV-2 infection was an independent predictor of reduced LV-GLS values (p < 0.001).
Conclusion
SARS-CoV-2 infection may affect left ventricular deformation in 30% of young adults patients despite an asymptomatic or only mildly symptomatic acute illness.
Speckle tracking echocardiography could help in early identification of patients with subclinical cardiac involvement. Since long-term complications of COVID-19 are not yet known, myocardial deformation imaging could be important for risk stratification, treatment and planning of long-term follow-up.

Background
Atrial fibrillation (AF) is the most common arrhythmia and one of the most prevalent cardiac disease. Restoring sinus rhythm improves long-term systolic and diastolic function, quality of life and relieve symptoms in patients with symptomatic AF.
Purpose
The aim of the study was to evaluate the early effects of AF direct current cardioversion on myocardial deformation using speckle-tracking echocardiography.
Methods
51 patients with persistent AF who underwent successful direct current cardioversion were enrolled (age: 70 ± 9 years; men: 72.5%). Patients with ischemic, dilatative, hypertrophic cardiomyopaties, valvular heart disease, previous cardiac interventions were excluded from the study. Left ventricular ejection fraction was 55.2 ± 7.0%. A transthoracic echocardiography was performed one day before the successful cardioversion and 6 hours after, employing 2d standard echocardiography and speckle-tracking technique to evaluate left atrial, left ventricular and free-wall right ventricular longitudinal strain.
Results
Restoration of sinus rhythm led to a reduction of the heart rate (83 ± 14 vs 70 ± 13 bpm, p < 0.001). After about six hours from successful AF direct current cardioversion, we highlighted an increase in left ventricular filling pressure estimated with the ratio E/E’ (8.19 ± 0.29 vs 9.34 ± 0.41, p = 0.0016). A significant increase in left atrial longitudinal strain (10.47 ± 0.64% vs 19.76 ± 1.01%, p < 0.001, Figure A) and in left ventricular longitudinal strain (-13.10 ± 0.60% vs -15.86 ± 0.51%, p < 0.001, Figure C) were noticed; also the free wall right ventricular longitudinal strain increased (-12.06 ± 1.16% vs -15.86 ± 1.29%, p = 0.047, Figure B).
Conclusion
Restoring sinus rhythm improves cardiac performance as evidenced by the increase in either left atrial and bi-ventricular longitudinal strain, suggesting an amelioration even if after early time. Abstract Figure

Abstract
PURPOSE The question whether the new cystic fibrosis transmembrane conductance regulator (CFTR) modulator drugs aimed at restoring CFTR protein function might improve glucose metabolism is gaining attention, but data on the effect of lumacaftor/ivacaftor treatment (LUMA/IVA) on glucose tolerance are limited. We evaluated the variation in glucose metabolism and insulin secretion in CF patients homozygous for Phe508del CFTR mutation after one-year treatment with LUMA/IVA in comparison to patients with the same genotype who did not receive such treatment. METHODS We performed a retrospective case-control study on 13 patients with a confirmed diagnosis of CF, homozygous for the Phe508del CFTR mutation, who received LUMA/IVA for one year (cases) and 13 patients with identical genotype who did not receive this treatment (controls). At the beginning and conclusion of the follow-up, all subjects received a modified 3 h OGTT, sampling at baseline, and at 30 min intervals for plasma glucose, serum insulin, and c-peptide concentrations to evaluate glucose tolerance, and quantify by modeling beta-cell insulin secretion responsiveness to glucose, insulin clearance and insulin sensitivity. RESULTS LUMA/IVA did not produce differences in glucose tolerance, insulin secretory parameters, clearance and sensitivity with respect to matched controls over one-year follow-up. CONCLUSION We found no evidence of improvements in glucose tolerance mechanisms in patients with CF after one-year treatment with LUMA/IVA.

Abstract
PURPOSE Reliable cut-offs for basal (bCT) and calcium stimulated calcitonin (casCT) are needed for an early and accurate diagnosis of medullary thyroid cancer (MTC). PATIENTS AND METHODS Fifty-four new patients with nodular goiter were enrolled and analysed together with those previously published by our group for a total of 135 cases. bCT and casCT were measured by a highly sensitive method and the results compared with histological findings. In a subgroup of patients, cardiac rhythm was recorded before and during the calcium test. RESULTS In both females (F) and males (M), there was a significant correlation between tumor size and bCT levels (P < 0.001). The receiver operating characteristic plot analyses showed that, for bCT, the new cut-off points able to separate non-MTC from MTC patients were > 30 (F) and > 34 pg/mL (M), whereas the best casCT thresholds were > 79 (F) and > 466 pg/mL (M). bCT was shown to harbour a high accuracy, though some cases were diagnosed only upon stimulation test. Importantly, combining bCT, below or above the cut-offs, with casCT above the cut-offs, all the MTC cases were correctly identified. A reversible sinus bradycardia was observed in 9% of cases during the test. CONCLUSIONS Refined cut-offs for bCT and casCT in patients with nodular goiter are reported. Sensitive bCT was shown to have a high accuracy, but the combination with casCT data was needed to identify all MTC cases. The reliability and safety of calcium test strongly favour the routine use of CT determination in nodular thyroid disease.

Abstract
Abstract
Background
Patient groups play an important role in health care and policy. Concerns have been raised about the financial ties between the pharmaceutical industry and patient groups, because of potential threats to the groups' independence. We conducted a systematic review to synthesise studies that explored pharmaceutical or medical device industry funding of patient groups.
Methods
We searched Medline, Embase, Web of Science, Scopus and Google Scholar (from inception to January 2018). We included observational studies reporting at least one of the following outcomes: prevalence of industry funding; proportion of industry funded patient groups which disclosed information about this funding; association between industry funding and organisational positions on health and policy issues. We carried out duplicate independent data extraction and assessed study quality.
Results
26 cross-sectional studies were included. Fifteen studies assessed the prevalence of industry funding, which ranged from 20% (12/61) to 83% (86/104). The proportion of patient groups which disclosed funding information on their websites was low (27% [95% CI: 24%-31%]). Few patient groups had formal policies governing corporate sponsorship (range from 2% (2/125) to 64% (175/274)). Among the few studies examining funding status versus organisational position, industry sponsored groups tend to hold positions consistent with sponsors' interests.
Conclusions
We found widespread indications of industry funding of patient groups. Transparency of funding is inadequate and the prevalence of policies governing corporate sponsorship is low. Research on policy impact is still limited. Considering the important role that patient groups play in health, strategies to prevent biases that may favour commercial interests above those of patients need to be implemented.
Key messages
Industry funding of patient groups is common in high income countries. Transparency of funding is inadequate and the prevalence of policies governing corporate sponsorship is low. Considering the important role that patient groups play in health care and policy, strategies to prevent biases that may favour commercial interests above those of patients need to be implemented.

Abstract
Soft tissue sarcomas constitute 1% of adult malignant tumors. They are a heterogeneous group of more than 50 different histologic types. Isolated limb perfusion is an established treatment strategy for locally advanced sarcomas. Since its adoption for sarcomas in 1992, after the addition of TNFα, few modifications have been done and although indications for the procedure are essentially the same across centers, technical details vary widely. The procedures mainly involves a 60 min perfusion with melphalan and TNFα under mild hyperthermia, achieving a limb preservation rate of 72-96%; with an overall response rates from 72 to 82.5% and an acceptable toxicity according to the Wieberdink scale. The local failure rate is 27% after a median follow up of 14-31 months compared to 40% of distant recurrences after a follow up of 12-22 months. Currently there is no consensus regarding the benefit of ILP per histotype, and the value of addition of radiotherapy or systemic treatment. Further developments towards individualized treatments will provide a better understanding of the population that can derive maximum benefit of ILP with the least morbidity.

Molecular markers for the classification of cytologically indeterminate thyroid nodules. J Endocrinol Invest 2020; 43:703-716. [PMID: 31853887 DOI: 10.1007/s40618-019-01164-w] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 12/11/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND The diagnosis of indeterminate lesions of the thyroid is a challenge in cytopathology practice. Indeed, up to 30% of cases lack the morphological features needed to provide definitive classification. Molecular tests have been developed to assist in the diagnosis of these indeterminate cases. The first studies dealing with the preoperative molecular evaluation of FNA samples focused on the analysis of BRAFV600E or on the combined evaluation of two or three genetic alterations. The sensitivity of molecular testing was then improved through the introduction of gene panels, which became available for clinical use in the late 2000s. Two different categories of molecular tests have been developed, the 'rule-out' methods, which aim to reduce the avoidable treatment of benign nodules, and the 'rule-in' tests that have the purpose to optimize surgical management. The genetic evaluation of indeterminate thyroid nodules is predicted to improve patient care, particularly if molecular tests are used appropriately and with the awareness of their advantages and weaknesses. The main disadvantage of these tests is the cost, which makes them rarely used in Europe. To overcome this limitation, customized panels have been set up, which are able to detect the most frequent genetic alterations of thyroid cancer. CONCLUSIONS In the present review, the most recent available versions of commercial molecular tests and of custom, non-commercial panels are described. Their characteristics and accuracy in the differential diagnosis of indeterminate nodules, namely Bethesda classes III (Atypical follicular lesion of undetermined significance, AUS/FLUS) and IV (Suspicious for follicular neoplasm, FN/SFN) are fully analyzed and discussed.

Use of a mobile application for self-management of pancreatic enzyme replacement therapy is associated with improved gastro-intestinal related quality of life in children with Cystic Fibrosis. J Cyst Fibros 2020; 19:562-568. [PMID: 32335023 DOI: 10.1016/j.jcf.2020.04.001] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 04/02/2020] [Accepted: 04/04/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Most patients with cystic fibrosis (CF) suffer from pancreatic insufficiency (PI), leading to fat malabsorption, malnutrition, abdominal discomfort and impaired growth. Pancreatic enzyme replacement therapy (PERT) is effective, but evidence based guidelines for dose adjustment are lacking. A mobile app for self-management of PERT was developed in the context of the HORIZON 2020 project MyCyFAPP. It contains an algorithm to calculate individual PERT-doses for optimal fat digestion, based on in vitro and in vivo studies carried out in the same project. In addition, the app includes a symptoms diary, educational material, and it is linked to a web tool allowing health care professionals to evaluate patient's data and provide feedback. METHODS A 6-month open label prospective multicenter interventional clinical trial was performed to assess effects of using the app on gastro-intestinal related quality of life (GI QOL), measured by the CF-PedsQL-GI (shortened, CF specific version of the Pediatric Quality of Life Inventory, Gastrointestinal Symptoms Module). RESULTS One hundred and seventy-one patients with CF and PI between 2 and 18 years were recruited at 6 European CF centers. Self-reported CF-PedsQL-GI improved significantly from month 0 (M0) (84.3, 76.4-90.3) to month 6 (M6) (89.4, 80.35-93.5) (p< 0.0001). Similar improvements were reported by parents. Lower baseline CF-PedsQL-GI was associated with a greater improvement at M6 (p < 0.001). CONCLUSIONS The results suggest that the MyCyFAPP may improve GI QOL for children with CF. This tool may help patients to improve self-management of PERT, especially those with considerable GI symptoms.

Abstract
IntroductionPatients affected by severe manic episode, often with delusional symptoms, are commonly treated with a combination of mood stabilizers, antipsychotics and other sedatives. The choice of a specific drug, dose and term is still debated.ObjectivesA naturalistic study on a sample of 84 inpatients affected by acute severe mania treated with a combination therapy.AimsTo compare efficacy and tolerability of haloperidol/risperidone/quetiapine in association with lithium and/or valproate.MethodsEighty-four bipolar inpatients affected by a manic episode according to DSM-5 criteria. Drugs administered according to our best practice. Clinical course weekly monitored with Young Mania Rating Scale (YMRS) for 4weeks. Extrapiramidal side effects (EPSE) monitored with Saint Hans Rating Scale (SHRS).ResultsTwenty-five men (29.76%) and 59 women (70.24%); mean age 43.37 ± 13.58 years. Mean YMRS score T0 40.27 ± 9.04. Forty-one patients (48.81%) treated with haloperidol (3.4 mg/die); 16 (19.05%) with risperidone (4.3 mg/die); 27 (32.14%) with quetiapine (438 mg/die). The 3 groups showed no difference regarding clinical characteristics and YMRS basal scores. Chi2 analysis confirmed an higher response rate (50% of reduction of YMRS final score compared to T0) with haloperidol (χ2 = 14.88; P = 0.00). The repeated-measures model analysis showed a significant decrease (P < 0.05) in YMRS scores in haloperidol vs. risperidone vs. quetiapine patients for all time points from second week. No statistical difference for EPSE was found.ConslusionsWe suggest that haloperidol could be advisable in the treatment of severe mania, with rapid efficacy, even with low doses. Occurrence of EPSE was not considerable during the acute treatment. Studies with a larger sample size, randomization, fixed doses, double blind design are needed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

We report a case of ileal carcinoid which clinically presented as a primary breast carcinoma. Review of the literature demonstrated only 9 cases of carcinoids metastatic to the breast. In spite of the rarity of this event, the differential diagnosis between primary and metastatic carcinoid of the breast should be considered in view of the different clinical management of these two settings.

Abstract
sGLOH (shifting GLOH) is a histogram-based keypoint descriptor that can be associated to multiple quantized rotations of the keypoint patch without any recomputation. This property can be exploited to define the best distance between two descriptor vectors, thus avoiding computing the dominant orientation. In addition, sGLOH can reject incongruous correspondences by adding a global constraint on the rotations either as an a priori knowledge or based on the data. This paper thoroughly reconsiders sGLOH and improves it in terms of robustness, speed and descriptor dimension. The revised sGLOH embeds more quantized rotations, thus yielding more correct matches. A novel fast matching scheme is also designed, which significantly reduces both computation time and memory usage. In addition, a new binarization technique based on comparisons inside each descriptor histogram is defined, yielding a more compact, faster, yet robust alternative. Results on an exhaustive comparative experimental evaluation show that the revised sGLOH descriptor incorporating the above ideas and combining them according to task requirements, improves in most cases the state of the art in both image matching and object recognition.

Abstract
This paper introduces a new compositional framework for classifying color correction methods according to their two main computational units. The framework was used to dissect fifteen among the best color correction algorithms and the computational units so derived, with the addition of four new units specifically designed for this work, were then reassembled in a combinatorial way to originate about one hundred distinct color correction methods, most of which never considered before. The above color correction methods were tested on three different existing datasets, including both real and artificial color transformations, plus a novel dataset of real image pairs categorized according to the kind of color alterations induced by specific acquisition setups. Differently from previous evaluations, special emphasis was given to effectiveness in real world applications, such as image mosaicing and stitching, where robustness with respect to strong image misalignments and light scattering effects is required. Experimental evidence is provided for the first time in terms of the most recent perceptual image quality metrics, which are known to be the closest to human judgment. Comparative results show that combinations of the new computational units are the most effective for real stitching scenarios, regardless of the specific source of color alteration. On the other hand, in the case of accurate image alignment and artificial color alterations, the best performing methods either use one of the new computational units, or are made up of fresh combinations of existing units.

Abstract
High calorie and fat consumption and the production of free radicals are two major mechanistic pathways between diet and disease. In this study we evaluated the effect of a plant-based diet poor in animal fat and rich in (n-3) fatty acids on fatty acids of serum phospholipids and on the production of reactive oxygen metabolites (ROMs). One hundred and four healthy female postmenopausal volunteers were recruited and randomized to a dietary intervention or a control group. Dietary intervention included a program of food education and biweekly common meals for 18 weeks. When the intervention and control groups were compared, it was seen that dietary intervention resulted in a significant reduction of saturated fatty acids (-1.5%) and a significant increase in (n-3) fatty acids (+20.6%), in particular docosahexaenoic acid (+24.8%). We observed that arachidonic acid decreased (–7.7%), while (n-6) fatty acids did not, and the (n-3)/(n-6) polyunsaturated ratio increased significantly (+24.1%). As expected, ROMs decreased significantly in the intervention group (-6%). The results indicated that a plant-based diet can improve the serum fatty acid profile and decrease ROMs production. These results suggest that a plant-based diet may reduce the body's exposure to oxidative stress.
