Abstract
A case of primary osteogenic sarcoma of the breast is reported. It should be distinguished from carcinoma with extensive osseous metaplasia. The results of light and electron microscopy including an immunohistochemical study are presented. Immunohistochemical and ultrastructural studies proved that the lesion, in the absence of epithelial differentiation, was a primary osteogenic sarcoma of the breast rather than a carcinoma with extensive osseous metaplasia. Diagnosis may be delayed because the tumor is confused clinically and mammographically with a calcific fibroadenoma.

Abstract
Background Given the incidence of breast cancer, histologic agreement is necessary to select the proper treatment. Methods & study design Twelve pathologists working in Puglia (Italy) independently evaluated a set of 88 slides of breast lesions. The set included 31 cases which presented difficulties at the moment of first diagnosis (problem cases) and 57 cases without problems (routine cases). Each pathologist was requested to classify lesions according to four categories: A, benign; B, atypical proliferation; C, in situ carcinoma; D, invasive carcinoma. For each case, the definite diagnosis was considered that provided by most of the pathologists (prevalent diagnosis). For the evaluation of degree of agreement, kappa statistics were utilized. Results Among routine cases, agreement was observed in 68.4% of cases (38/57) and in 29% of problem cases (9/31). The pair-wise comparison between all participating pathologists showed a good overall agreement, (kappa mean, 0.66; range, 0.57-0.76). The agreement of each pathologist with the prevalent diagnosis was high for invasive (mean kappa, 0.88) and benign lesions (mean kappa, 0.83) followed by in situ carcinoma (mean kappa, 0.64). The lowest value observed was for atypical lesions (mean kappa, 0.25). Conclusions The results showed a good overall degree of diagnostic concordance among participating pathologists, all working in the Italian region of Puglia. The findings emerging from the study are comparable to those of other studies performed with selected pathologists specifically specialized in breast pathology. Moreover, the study confirmed the diagnostic difficulties for borderline lesions and the necessity of further investigation for sclerosing lesions with discordant diagnoses.

Abstract
The authors report on a retrospective consecutive multicentric series of 60 cases with histologic evidence of lobular carcinoma in situ (LCIS), followed for an average of 5.3 years. In the course of the follow-up, ipsilateral LCIS or infiltrating carcinoma occurred in 3 or 5 cases, respectively. Two LCIS reoccurrences and all ipsilateral infiltrating carcinomas were observed in 37 patients treated by limited surgery. Contralateral synchronous or metachronous carcinoma was observed in 3 or 2 cases, respectively (intraductal = 3, infiltrating = 2). Three patients died of breast cancer (2 with Ipsilateral, 1 with ipsilateral and contralateral infiltrating carcinoma). The study confirms the higher risk of ipsilateral and contralateral cancer in LCIS patients and warns about the possible hazards of limited surgery in these cases.

Abstract
The risk of developing breast cancer was investigated in 339 patients in whom histologically confirmed intraductal papilloma had been surgically removed. Follow-up ranged from 2 to 14 years, (average, 6.62 years). Ten breast cancers were observed, whereas 3 were expected on the basis of age-specific incidence rates drawn from local cancer registries (relative risk = 3.33, 95% confidence interval = 1.60-6.13). No significant difference in the relative risk was observed as far as papilloma type (single or multiple) was concerned. All breast cancers observed occurred in the same breast as the papilloma. Women in whom a benign intraductal papilloma has been excised should be carefully followed since they at are higher risk for ipsilateral breast cancer.

Abstract
Aims and background The association of p53 protein accumulation and prognosis in node-negative breast cancer patients has been alternately demonstrated and denied in literature reports, and opinions on the use of p53 expression as an indicator of high risk of recurrence and as a guide for adjuvant therapy are controversial. Study design The association of p53 protein accumulation with prognosis was retrospectively evaluated in a series of 221 node-negative breast cancer patients treated with surgery alone and followed up for a minimum of 10 years. p53 accumulation was determined by immunohistochemistry on archive material, and classified into four grades of increasing immunostaining. Results No association was observed between p53 and age or pT category, whereas a significant association with nuclear grade was found (P = 0.0014). Univariate and multivariate analysis of 10-yr disease-free and overall survival showed a significant and independent prognostic association for tumor size (pT category) and nuclear grading but not for p53 expression, whatever grade grouping was used. Conclusions We did not find any evidence supporting the use of p53 immunostaining in current practice as an independent prognostic indicator or as a discriminant factor for adjuvant treatment of node-negative breast cancer patients.

Abstract
The authors report on a series of 529 consecutive patients examined on physical examination, mammography, nipple discharge cytology and galactography. The criterion for galactography was essentially bloody nipple discharge (73% of cases). Serous nipple discharge was not considered worthy of routine galactography since it is associated with an extremely low incidence of breast cancer. Surgical excision and histologic examination of the discharging duct was performed in 200 cases. Eighteen cases of breast cancer were detected (10 infiltrating, 8 intraductal) of which 9, 6, 7 or 7 were suspected on physical examination, mammography, cytology or galactography, respectively. All combined tests suspected 13 of 18 breast cancers; 3 intraductal breast cancers were biopsied because of evidence of multiple papillomas on galactography, and 2 infiltrating breast cancers were operated because of persistent bloody nipple discharge in the absence of any other sign. No breast cancer was suspected on galactography alone. Galactography is indicated in the presence of bloody nipple discharge, and a biopsy should be performed when breast cancer or multiple papillomas are suspected. The diagnosis and excision of a single papilloma (breast cancer was never misdiagnosed as a single papilloma on galactography) is not worthwhile since a single papilloma is a benign lesion, and the benefit of its excision is still unclear.

Abstract
Abstract
Introduction. Invasive apocrine carcinoma of the breast is a rare type of breast cancer (BC), pure apocrine carcinoma constitutes <1% of all BC. Mammary apocrine epithelium has a characteristic steroid receptor profile that is negative for full length estrogen receptor-alpha and progesterone receptor and is androgen receptor positive. Conflicting data are available on the outcome of this type of disease: few studies reported significantly different prognosis of triple negative (TN) apocrine carcinomas when compared to most non-apocrine triple negative (NA-TN) tumors. The aim of this study is to report our long-term experience in a single-center series of TN apocrine tumors.
Methods. We analyzed clinical and pathological features of a series of TN apocrine carcinomas treated at our Centre in a 15-year period. Clinical and pathological characteristics and outcomes have been compared with a control series of NA-TN tumors treated during the same follow up period. Local relapse-free survival (LRFS), distant metastases-free survival (DMFS), and overall survival (OS) have been evaluated and compared between groups of patients.
Results. Forty-five TN apocrine carcinomas were analyzed. The mean age at diagnosis was 60 years (range 34-83 years). The proportions of apocrine tumor grades varied, with G1 being seen in 6.8% of patients, G2 in 51.1%, and G3 in 40.1%. The majority of apocrine carcinomas had small tumor size (T1: 72.7%; T2: 27.3%), and negative axillary nodal status (66.7%). The series was compared to a homogenous control group of 45 NA-TN patients. The mean age was 54 years (range 32-79 years), affected by high grade (G3: 53.7%), small tumor size (T1: 87.5%; T2: 12.5%), and mostly negative axillary nodal status (82.9%). LRFS in the apocrine group was 85% and 78% at 5- and 10-year, respectively. LRFS in the NA-TN group was 90% and 79% at 5- and 10-year, respectively. No difference was evidenced between groups (HR 1.44 95%CI 0.62-3.79; p=0.39). DMFS in the apocrine group was 85% and 85% at 5- and 10-years, respectively. DMFS in the NA-TN group was 85% and 75% at 5- and 10-year, respectively. DMFS was significantly better in the apocrine group (HR 0.69 95%CI 0.28-1.62). OS in the apocrine group was 86% and 83% at 5- and 10-year, respectively. OS in the NA-TN group was 86% and 63% at 5- and 10-years, respectively. OS was significantly better in the apocrine group (HR 0.57 95%CI 0.26-1.18).
Conclusions. Apocrine carcinomas represent a clinic-pathological distinct group of triple-negative BC, characterized by significantly more favorable clinical prognosis in terms of long-term disease-related morbidity or mortality when compared to NA-TN tumors.

Abstract
The clinical interest in HER-2/neu is related to trastuzumab, a drug used to treat patients with invasive breast carcinoma overexpressing the HER-2/neu protein. It is very important to correctly identify those patients who may benefit from trastuzumab by accurate assessment of the HER-2/neu status. Of the various methods available, the Dako Herceptest for immunohistochemical assay is considered the most reliable to reach this goal. The aim of this study was to investigate within a group of Italian laboratories the reproducibility of the results of HER-2/neu assessment by means of the Dako scoring system on slides stained with the Herceptest kit. This study was also conceived as the continuation of one of our previous studies, which was similar in its aims but different in the classification criteria adopted. Our results show that, whereas the intra-observer reproducibility was generally satisfactory, the interobserver reproducibility was not. Moreover, our findings confirm that the two extreme classes (0 and 3+) are more easy to identify than the other two and that the Herceptest does not allow to discriminate optimally between scoring classes 2+ and 3+. These findings are relevant in clinical practice where the treatment choice is based on categories defined by this assay, suggesting the need of adopting educational programs and/or new reference materials to improve the assay performance.

Abstract
Implantology research framed the implant surface as a key element for a good and sustainable osseointegration of an implant fixture. The aim of this study was to analyze the antibacterial properties of anatase-coated titanium healing screws through microbiological and scanning electron microscopy. The comparison of the bacterial colonies growth between the anatase-coated titanium healing screws and non-coated titanium healing screws showed comparable antibacterial properties, without significant statistical differences. The scanning electron microscopy observations confirmed the microbiological study. These data, also considering previous reports on the positive effects on osteoblasts genetic expressions, might suggest a use of the anatase-coated titanium healing screws to preserve the tissues surrounding implants from microbial attacks.

Abstract
OBJECTIVES Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral small vessel disease caused by NOTCH3 gene mutations. CADASIL women are frequently considered at high risk of systemic vascular events during pregnancy and often prescribed with antithrombotic drugs. This decision is not evidence-based considering the lack of data about pregnancy outcome in CADASIL. We describe our experience on pregnancy in CADASIL patients. MATERIALS AND METHODS We reviewed records of 50 CADASIL females followed in our center, and we collected prospective information in six patients for a total of 93 pregnancies. RESULTS No woman had the disease onset or suffered from cerebral vascular ischemic events during pregnancy. Sixteen miscarriages (17.2%) were recorded. There were 72 vaginal births, and five cesarean sections. Considering the six patients followed prospectively (for a total of eight pregnancies), data on fetal growth and newborns weight were in line with those from the general population. Considering gestational complications, we recorded mild proteinuria without hypertension in one patient and hyperinsulinemia and pre-eclampsia in another affected by a known nephropathy. Antithrombotic drugs were used in three patients, in one for an unrelated coexisting prothrombotic condition. CONCLUSIONS CADASIL does not seem to be associated with an unfavorable outcome of pregnancy either for women and fetuses. Patients and treating physicians should be reassured that pregnancy can be safely initiated in CADASIL, as there is no evidence to support a specific preventive antithrombotic treatment during pregnancy in CADASIL. Larger studies are needed to definitively confirm these conclusions.

Abstract
RESUMO A cicatrização de feridas é um processo que requer a interação de várias células da derme e epiderme. O objetivo deste trabalho foi avaliar qual o momento da aplicação das células das ADSCs em feridas cutâneas agudas que faria diferença na cicatrização nos primeiros sete dias da lesão. As células-tronco foram isoladas do tecido adiposo de camundongos C57Bl/6 GFP+. Para tanto, foram utilizados 49 camundongos C57Bl/6, divididos em quatro grupos: grupo I (GI/controle; n=14); grupo II (GII; n=14): ADSCs injetadas no d0; grupo III (GIII; n=14): ADSCs injetadas no terceiro dia; e Grupo IV (GIV; n=7): ADSCs injetadas no quinto dia. As avaliações clínicas ocorreram nos dias zero, três, cinco e sete, e as histopatológicas nos dias cinco e sete. Na metodologia proposta, foi observado que o uso de ADSCs aumenta a vascularização, a formação de tecido de granulação, a colagenização e incrementa o número de folículos pilosos em apenas sete dias de avaliação. Além disso, o momento da aplicação das células não repercutiu diferenças significativas nas fases inflamatória e proliferativa do processo de cicatrização das feridas cutâneas.

Abstract
Oral surgery procedures involve traumatization of mucosal and bony tissues, and lengthy interventions can lead to inflammatory post-operative sequelae. In the bony tissues in particular, the inflammatory processes can affect healing. Modern drug therapies provide valid support for lowering the risk of occurrence of post-operative inflammatory signs. The two main types of agents used are nonsteroidal anti-inflammatory drugs and/or corticosteroids, which act on two different molecular pathways in the inflammatiory process. The aim of this systematic review is to examine the different corticosteroids used in oral surgery procedures, their indications for use, and their route of administration, to provide the clinician with a useful scheme for correct pharmacological management of post-operative inflammation. To identify studies eligible for inclusion in this systematic review, we performed a literature search up to April 2017 of the electronic databases, considering published papers from 2007 to 2017. The search terms included steroids, third molar, oral surgery, RCT [randomized controlled trial], human, and clinical trial. Only articles in English language were considered.

Abstract
This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non-medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were €7422 (±€6255) for stage 4 and €8971 (±€6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was €1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system.

Abstract
Brain-inspired computation can revolutionize information technology by introducing machines capable of recognizing patterns (images, speech, video) and interacting with the external world in a cognitive, humanlike way. Achieving this goal requires first to gain a detailed understanding of the brain operation, and second to identify a scalable microelectronic technology capable of reproducing some of the inherent functions of the human brain, such as the high synaptic connectivity (~104) and the peculiar time-dependent synaptic plasticity. Here we demonstrate unsupervised learning and tracking in a spiking neural network with memristive synapses, where synaptic weights are updated via brain-inspired spike timing dependent plasticity (STDP). The synaptic conductance is updated by the local time-dependent superposition of pre- and post-synaptic spikes within a hybrid one-transistor/one-resistor (1T1R) memristive synapse. Only 2 synaptic states, namely the low resistance state (LRS) and the high resistance state (HRS), are sufficient to learn and recognize patterns. Unsupervised learning of a static pattern and tracking of a dynamic pattern of up to 4 × 4 pixels are demonstrated, paving the way for intelligent hardware technology with up-scaled memristive neural networks.

Abstract
Abstract
Background. Accelerated partial breast irradiation (APBI) represents a valid option for selected early breast cancer (BC); potential advantages of APBI include shorter treatment time, improved safety profile, and a cost reduction compared with standard fractionation.
We reported the final analysis of quality of life (QOL) results from a phase 3 randomized trial comparing standard adjuvant radiotherapy (50 Gy in 25 fractions, plus 10 Gy boost) to APBI using IMRT technique (30 Gy in 5 daily fractions). The 5-year results have been recently published showing equivalence in terms of local control (ClinicalTrials.gov, NCT02104895).
Methods. Overall 205 patients (105 APBI and 100 WBI) fully completed the given questionnaires at time 0 (RT start), time 1 (RT end), and time 2 (2-year follow up). Patients were asked to compile two specific questionnaires on QOL, the EORTC QLQ-C30 as a reliable and valid measure of the QOL of cancer patients in multicultural clinical research settings, and the BR23 module as a supplementary questionnaire for assessing QOL issues relevant to patients with BC. The statistical software SPSS (SPSS Inc, Chicago, IL, USA) for Windows (version 22), and STATA (StataCorp LP, College Station TX77845, USA) for Windows (version 12) were used. Chi-squared test or Mann Whitney U test were used to compare the individual characteristics of the patients between two arms. Mean and standard deviations (SD) were calculated for all QOL domains, and all scores were compared between APBI and WBI arms using the Mann Whitney test due to non-parametric distribution of data. The Kruskal-Wallis test was used to compare the scores between age groups.
Results. Mean values (and SD) of QLQ-C30 scores according to arm in the series of 205 BC patients at time 2 (time 0 vs time 2), showed significant improvement in favor of APBI in terms of global health status (mean 75.5 vs 59.5, SD range 13.3-22.0; p<0.0001), main functional (p<0.01), and symptom scales (p<0.01). Concerning the BR23 module, APBI showed significantly better outcome in terms of body image perception (mean 89 vs 72.1, SD 13.2-26.6; p<0.0001) and future perspective (84.8 vs 57, SD 23.1-28.5; p<0.0001) among functional scales; breast (6.1 vs 18.9, SD 6.6-18.2; p<0.0001) and arm symptoms (11.7 vs 19.6, SD 13.4-19; p=0.002) among symptom scales.
Conclusions. Women treated with APBI reported a significantly better QOL outcome as compared with women treated using WBI. QOL improvement was evidenced in terms of functional, symptoms, and global health status/QOL scales, both at the end of radiation and at a 2-year follow-up time.

Abstract
Abstract
Background. Several randomized trials demonstrated aromatase inhibitors (AI) superiority in terms of disease-free survival compared to tamoxifen treatment for postmenopausal hormone receptor-positive breast cancer (BC) patients. Anyway AI toxicity profile due to estrogen suppression is a concern. Pivotal trials demonstrated a significant bone mineral density (BMD) loss due to AI, with a consistent risk of fractures, thus impacting on patients' quality of life.
Bisphosphonates represent an effective treatment in postmenopausal osteoporosis fractures prevention. Several studies demonstrated that upfront bisphosphonates therapy prevents bone loss in postmenopausal women receiving adjuvant AI for early-stage BC. However an adequate patients selection for adjuvant bisphosphonates treatment during AI endocrine therapy is still a challenge.
We present the final results of the BONADIUV trial, a single-blind, randomized, placebo-controlled phase 2 study designed to evaluate the impact of ibandronate treatment on BMD in osteopenic women taking AI.
Methods. Between January 2011 and May 2014, 561 patients underwent a baseline BMD assessment before starting AI as planned adjuvant treatment. Overall 171 osteopenic patients (lumbar spine [LS] and/or trochanter -1< T-score <-2.5), were randomized in a 1:1 ratio to receive either placebo or oral monthly ibandronate (150 mg). All patients receive oral supplementation of calcium and vitamin D3. Study duration was 2 years. Exclusion criteria were: premenopausal status at time of randomization; comorbidities with increased risk of osteoporosis; body mass index <18; chronic use of steroids; previous use of bisphosphonates; psychiatric disorders. Primary endpoint was the mean BMD difference between the two arms at a 2-year follow up. ClinicalTrials.gov identifier: NCT02616744. A total of 72 patients per arm of treatment were needed to obtain an 85% statistical power in order to detect a 2% BMD mean difference between the two arms. Considering a 10% dropout, at least 158 patients were required.
Results. A total of 171 patients were randomized in the study. Overall 27 patients (15.8%) withdrew the protocol (17 ibandronate vs 10 placebo arm): the final analysis was performed on 144 patients (72 patients per arm). P-value from Wilcoxon test showed no significant difference between arms at baseline both for LS (p=0.94) and trochanter (p=0.83).
At 2-year, osteopenic patients treated with ibandronate gained +18.7% and +15.5% at the LS and trochanter BMD, respectively. Patients treated with placebo lost -13.3% at the LS, and gained +2.9% at the trochanter.
Trochanter p-value from covariance analysis showed a mean BMD change significantly in favor of ibandronate arm at 1-year (p=0.012), and borderline at 2-year (p=0.087). Concerning LS, the mean BMD change was significantly in favor of ibandronate arm both at 1-year (p=0.002) and 2-year (p<0.0001).
Conclusions. Final results of our study showed that treatment with ibandronate, as compared to placebo, improved BMD change in osteopenic women treated with adjuvant AI, and consistently protected patients' bone loss.

Abstract
BACKGROUND Core needle biopsy (CNB) plays a crucial role as diagnostic tool for breast cancer (BC). The characterization of biomarkers status before surgical treatment is crucial when primary systemic therapy is a therapeutic option. The aim of this analysis was to report concordance between preoperative CNB and surgical specimen (SS) in evaluating biomarkers and molecular subtypes. METHODS Data have been collected from a cohort of 101 patients affected by early BC treated at Careggi Florence University Hospital, between January 2014 and March 2015. The conformity between molecular subtype classification was tested using kappa (κ) test. RESULTS Mean age was 57.5 years (range 29-86). There was concordance between the estrogen receptor (ER) assessment on CNB and SS in 95 cases (94.1%). Concordance of the progesterone receptor (PgR) assessment was observed in 89 cases (88.1%). Concordance for detecting immunohistochemistry-assessed BC molecular subtypes was 87.1% (κ = 0.78). Concerning Ki-67 evaluation, we report a concordance rate of 88.1% (κ = 0.68). The evaluation of luminal A plus luminal B/HER negative subgroup showed a κ-value of 0.65. CONCLUSIONS CNB showed good accuracy in evaluating hormonal receptors status, HER2, and BC molecular subtypes. Evaluation of Ki67 status was less accurate than other biomarkers; therefore, we recommend that it should be detected both on CNB and SS samples, especially in hormonal positive HER2 negative tumors, in order to avoid a misclassification of tumor subtypes that could lead to an omission of potential effective systemic therapy.

Abstract
We demonstrate that Digital Holographic Microscopy can be used for accurate 3D tracking and sizing of a colloidal probe trapped in a diamond anvil cell (DAC). Polystyrene beads were optically trapped in water up to Gigapascal pressures while simultaneously recording in-line holograms at 1 KHz frame rate. Using Lorenz-Mie scattering theory to fit interference patterns, we detected a 10% shrinking in the bead's radius due to the high applied pressure. Accurate bead sizing is crucial for obtaining reliable viscosity measurements and provides a convenient optical tool for the determination of the bulk modulus of probe material. Our technique may provide a new method for pressure measurements inside a DAC.

Abstract
Nutritional abnormalities and physical inactivity are risk factors of increased morbidity and mortality in patients with ESRD. Identify and define malnutrition, in particular protein-energy depletion (PEW), is an important task in the management of renal patients. The aim of this multicenter observational study was to implement the assessment of nutritional status and functional capacity in patients on peritoneal dialysis, including tests and validated methods which are relatively easy to apply in daily clinical practice. The study includes all the 133 prevalent patients (80 m, 53 f, age 65 14 years), in peritoneal dialysis treatment (vintage 26 19 months) in 9 centers in Tuscany. We performed anthropometry, bioimpedance (BIA), clinical biochemistry, evaluation of habitual physical activity (RAPA tests) and performance (Sit-To-Stand test), appetite-evaluation questionnaire, and indices including the Malnutrition Inflammation Score (MIS), Geriatric Nutrition Risk Index (GNRI), Charlson comorbidity index, Barthel and Karnowsky index. The latter showed a condition of dependence in 7.2% and 19.7% of cases, respectively. Poor appetite was recorded in 48.2%. The majority of patients fell within the overweight / obesity range (51%) with waist circumference values associated with increased cardiovascular risk in 51% of males and 60% of females. At the BIA analysis, a BCMI <8 kg/m2 was detected in 39% of patients; an estimated protein intake <1.0 g / kg/d was found in 59% of cases; 34% of patients had serum albumin <3.5 g / dl; control of acidosis was good (bicarbonate 25.4 3.8 mM) but hyperphosphatemia was present in 64.6% of patients. A condition of sedentary or light physical activity was reported by 65.1% of patients, vigorous activity only by 11.9%. The 86.5% of patients able to perform the Sit-to-stand test reported a lower than the reference values for age and sex. A diagnosis of PEW was possible in 8% of our series, while a MIS score> 11, indicative of PEW, took place in 12.7% of cases. The values of the MIS correlated directly with age and the degree of comorbidity and inversely with the sit-to-stand test, RAPA tests and appetite level. The data in this study show that single tests indicative of malnutrition disorders are frequent to be found in our series of peritoneal dialysis patients. However, a diagnosis of PEW is quite infrequent. A large percentage of patients are overweight with increased abdominal adiposity, and reduced cell mass and protein intake below recommended levels; the level of habitual physical activity is low, and the level of physical capability is scarce. Therefore it is conceivable a nutritional counseling intervention to increase the intake of proteins, limiting the phosphorus and (when indicated) energy intake and to stimulating spontaneous physical activity or arranging assisted programs for functional rehabilitation. Close monitoring of the nutritional status and implementation of programs of adapted physical activity should have a prominent role in the clinical management of patients on peritoneal dialysis.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease resulting in death, usually from respiratory failure, within 2-3 years of symptom onset. Non-invasive ventilation (NIV) is a treatment that when given to patients in respiratory failure leads to improved survival and quality of life. Diaphragm pacing (DP), using the NeuRx/4(®) diaphragm pacing system (DPS)™ (Synapse Biomedical, Oberlin, OH, USA), is a new technique that may offer additional or alternative benefits to patients with ALS who are in respiratory failure. OBJECTIVE The Diaphragm Pacing in patients with Amyotrophic Lateral Sclerosis (DiPALS) trial evaluated the effect of DP on survival over the study duration in patients with ALS with respiratory failure. DESIGN The DiPALS trial was a multicentre, parallel-group, open-label, randomised controlled trial incorporating health economic analyses and a qualitative longitudinal substudy. PARTICIPANTS Eligible participants had a diagnosis of ALS (ALS laboratory-supported probable, clinically probable or clinically definite according to the World Federation of Neurology revised El Escorial criteria), had been stabilised on riluzole for 30 days, were aged ≥ 18 years and were in respiratory failure. We planned to recruit 108 patients from seven UK-based specialist ALS or respiratory centres. Allocation was performed using 1 : 1 non-deterministic minimisation. INTERVENTIONS Participants were randomised to either standard care (NIV alone) or standard care (NIV) plus DP using the NeuRX/4 DPS. MAIN OUTCOME MEASURES The primary outcome was overall survival, defined as the time from randomisation to death from any cause. Secondary outcomes were patient quality of life [assessed by European Quality of Life-5 Dimensions, three levels (EQ-5D-3L), Short Form questionnaire-36 items and Sleep Apnoea Quality of Life Index questionnaire]; carer quality of life (EQ-5D-3L and Caregiver Burden Inventory); cost-utility analysis and health-care resource use; tolerability and adverse events. Acceptability and attitudes to DP were assessed in a qualitative substudy. RESULTS In total, 74 participants were randomised into the trial and analysed, 37 participants to NIV plus pacing and 37 to standard care, before the Data Monitoring and Ethics Committee advised initial suspension of recruitment (December 2013) and subsequent discontinuation of pacing (on safety grounds) in all patients (June 2014). Follow-up assessments continued until the planned end of the study in December 2014. The median survival (interquartile range) was 22.5 months (lower quartile 11.8 months; upper quartile not reached) in the NIV arm and 11.0 months (6.7 to 17.0 months) in the NIV plus pacing arm, with an adjusted hazard ratio of 2.27 (95% confidence interval 1.22 to 4.25; p = 0.01). CONCLUSIONS Diaphragmatic pacing should not be used as a routine treatment for patients with ALS in respiratory failure. FUTURE WORK It may be that certain population subgroups benefit from DP. We are unable to explain the mechanism behind the excess mortality in the pacing arm, something the small trial size cannot help address. Future research should investigate the mechanism by which harm or benefit occurs further. TRIAL REGISTRATION Current Controlled Trials ISRCTN53817913.

Abstract
Hoffa's (infrapatellar) fat pad (HFP) is one of the knee fat pads interposed between the joint capsule and the synovium. Located posterior to patellar tendon and anterior to the capsule, the HFP is richly innervated and, therefore, one of the sources of anterior knee pain. Repetitive local microtraumas, impingement, and surgery causing local bleeding and inflammation are the most frequent causes of HFP pain and can lead to a variety of arthrofibrotic lesions. In addition, the HFP may be secondarily involved to menisci and ligaments disorders, injuries of the patellar tendon and synovial disorders. Patients with oedema or abnormalities of the HFP on magnetic resonance imaging (MRI) are often symptomatic; however, these changes can also be seen in asymptomatic patients. Radiologists should be cautious in emphasising abnormalities of HFP since they do not always cause pain and/or difficulty in walking and, therefore, do not require therapy. Teaching Points • Hoffa's fat pad (HFP) is richly innervated and, therefore, a source of anterior knee pain. • HFP disorders are related to traumas, involvement from adjacent disorders and masses. • Patients with abnormalities of the HFP on MRI are often but not always symptomatic. • Radiologists should be cautious in emphasising abnormalities of HFP.

Abstract
PURPOSE Childbearing delay contributes to the increase of subfertile couples that require assisted reproductive technology (ART). Subfertility relates with reproductive aging (RA). In vitro aging (IvA) (due to extended culture) may also impair oocyte competence. Aims of this study were to evaluate and compare the oocyte ultrastructure after RA and IvA. METHODS Cumulus-oocyte complexes (COCs) (n = 68), with metaphase II oocyte and expanded cumulus, from consenting patients (<35 years old and ≥35 years old, n = 36), were selected by phase contrast microscopy and fixed at pick up, or after 24 h culture. COCs (n = 44) were studied by light and qualitative/morphometric transmission electron microscopy. Two-way ANOVA, with age and culture as grouping factors, was applied for statistical analysis (p < 0.05). Metaphase II cumulus-free oocytes (n = 24) were selected for confocal microscopy observations. RESULTS Significant decrease of mitochondria-smooth endoplasmic reticulum aggregates, increase of mitochondria-vesicle complexes size and amount, decrease of cortical granules and microvilli, and alterations of the spindle structure characterized both RA and IvA oocytes. These changes were significantly more evident in the RA oocytes submitted to IvA. RA oocytes also showed changes of the zona pellucida and occurrence of vacuoles after culture. Cumuli appeared re-compacted after culture, irrespective of the age of the patients. CONCLUSIONS These data demonstrated that aging is related to decay of oocyte ultrastructural quality, and that oocytes from elder women are more sensitive to prolonged culture (IvA) than the oocytes from younger women. These morphological results should be considered when applying ART in aged patients, rescue ICSI, or artificial oocyte activation.

Abstract
E. coli bacteria swim following a run and tumble pattern. In the run state all flagella join in a single helical bundle that propels the cell body along approximately straight paths. When one or more flagellar motors reverse direction the bundle unwinds and the cell randomizes its orientation. This basic picture represents an idealization of a much more complex dynamical problem. Although it has been shown that bundle formation can occur at either pole of the cell, it is still unclear whether these two run states correspond to asymmetric propulsion features. Using holographic microscopy we record the 3D motions of individual bacteria swimming in optical traps. We find that most cells possess two run states characterized by different propulsion forces, total torque, and bundle conformations. We analyze the statistical properties of bundle reversal and compare the hydrodynamic features of forward and backward running states. Our method is naturally multi-particle and opens up the way towards controlled hydrodynamic studies of interacting swimming cells.

Abstract
OBJECTIVES Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited small vessel disease caused by NOTCH3 mutations. There are no clinical and neuroimaging findings pathognomonic of the disease. The aim of this paper was to provide a description of a group of NOTCH3-negative patients with a phenotype closely resembling that of CADASIL. MATERIALS AND METHODS We performed NOTCH3 analysis (exons 2-23) in 117 probands because of a clinician's suspicion of CADASIL. The CADASIL scale, a recently developed tool that allows to better select patients for NOTCH3 analysis, was retrospectively applied to NOTCH3-negative patients; the patient subgroup that scored higher than the screening cutoff for CADASIL was defined as CADASIL-like. RESULTS Thirty-four CADASIL-like patients (mean age at onset 57.8 years [52.1-63.4], 50% males) were identified. Compared with 25 patients with CADASIL for clinical, familial, and neuroimaging features, only the following variables were significantly (α level <0.05) different in frequency between patients with CADASIL and CADASIL-like patients: a positive family history for stroke at age ≤ 60 years, more frequent in patients with CADASIL, and hypertension, more frequent in CADASIL-like patients. CONCLUSIONS Our experience highlights the growing number of patients presenting with a high suspicion of a cerebral small vessel disease with an autosomal dominant pattern of inheritance and a phenotype closely similar to that of CADASIL but without NOTCH3 mutations. This group remains to be characterized from the genetic point of view. The role of other genes or NOTCH3 alterations on exons other than 2-23 or introns has to be further assessed.

Abstract
Male breast cancer (MBC) is rare and poorly understood. Like female breast cancer (FBC), MBCs are highly sensitive to hormonal changes, and hyperestrogenism, specifically, represents a major risk factor for MBC. MBC is considered similar to late-onset, post-menopausal estrogen/progesteron receptors positive FBC (ER+/PR+). Sulfotransferase 1A1 (SULT1A1) is an enzyme involved in the metabolism of estrogens. Recently, SULT1A1 common functional polymorphism Arg(213)His (638G>A) variant has been found to be associated with increased breast cancer (BC) risk, particularly in post-menopausal women. For this reason, we decided to explore whether SULT1A1 Arg(213)His could exert an effect on MBC development. The primary aim of this study was to evaluate the influence of the SULT1A1 Arg(213)His polymorphism on MBC risk. The secondary aim was to investigate possible associations with relevant clinical-pathologic features of MBC. A total of 394 MBC cases and 786 healthy male controls were genotyped for SULT1A1 Arg(213)His polymorphism by PCR-RFLP and high-resolution melting analysis. All MBC cases were characterized for relevant clinical-pathologic features. A significant difference in the distribution of SULT1A1 Arg(213)His genotypes was found between MBC cases and controls (P < 0.0001). The analysis of genotype-specific risk showed a significant increased MBC risk in individuals with G/A (OR 1.97, 95% CI 1.50-2.59; P < 0.0001) and A/A (OR 3.09, 95% CI 1.83-5.23; P < 0.0001) genotypes in comparison to wild-type genotype, under co-dominant model. A significant association between SULT1A1 risk genotypes and HER2 status emerged. Results indicate that SULT1A1 Arg(213)His may act as a low-penetrance risk allele for developing MBC and could be associated with a specific tumor subtype associated with HER2 overexpression.

Abstract
The correct identification of HER2-positive cases is a key point to provide the most appropriate therapy to breast cancer (BC) patients. We aimed at investigating the reproducibility and accuracy of HER2 expression by immunohistochemistry (IHC) in a selected series of 35 invasive BC cases across the pathological anatomy laboratories in Tuscany, Italy. Unstained sections of each BC case were sent to 12 participating laboratories. Pathologists were required to score according to the Food and Drug Administration (FDA) four-tier scoring system (0, 1+, 2+, 3+). Sixteen and nineteen cases were HER2 non-amplified and amplified respectively on fluorescence in situ hybridization. Among 192 readings of the 16 HER2 non-amplified samples, 153 (79.7%) were coded as 0 or 1+, 39 (20.3%) were 2+, and none was 3+ (false positive rate 0%). Among 228 readings of the 19 HER2 amplified samples, 56 (24.6%) were scored 0 or 1+, 79 (34.6%) were 2+, and 93 (40.8%) were 3+. The average sensitivity was 75.4%, ranging between 47% and 100%, and the overall false negative rate was 24.6%. Participation of pathological anatomy laboratories performing HER2 testing by IHC in external quality assurance programs should be made mandatory, as the system is able to identify laboratories with suboptimal performance that may need technical advice. Updated 2013 ASCO/CAP recommendations should be adopted as the widening of IHC 2+ "equivocal" category would improve overall accuracy of HER2 testing, as more cases would be classified in this category and, consequently, tested with an in situ hybridisation method.
