Abstract
We present results from an analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season. This includes the first Keck Array observations at 95 GHz. The maps reach a depth of 50 nK deg in Stokes Q and U in the 150 GHz band and 127 nK deg in the 95 GHz band. We take auto- and cross-spectra between these maps and publicly available maps from WMAP and Planck at frequencies from 23 to 353 GHz. An excess over lensed ΛCDM is detected at modest significance in the 95×150 BB spectrum, and is consistent with the dust contribution expected from our previous work. No significant evidence for synchrotron emission is found in spectra such as 23×95, or for correlation between the dust and synchrotron sky patterns in spectra such as 23×353. We take the likelihood of all the spectra for a multicomponent model including lensed ΛCDM, dust, synchrotron, and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r) using priors on the frequency spectral behaviors of dust and synchrotron emission from previous analyses of WMAP and Planck data in other regions of the sky. This analysis yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors. Combining these B-mode results with the (more model-dependent) constraints from Planck analysis of CMB temperature plus baryon acoustic oscillations and other data yields a combined limit r_{0.05}<0.07 at 95% confidence. These are the strongest constraints to date on inflationary gravitational waves.

Abstract
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven frequencies from 30 to 353 GHz, but much less deeply in any given region (1.2 μK deg in Q and U at 143 GHz). We detect 150×353 cross-correlation in B modes at high significance. We fit the single- and cross-frequency power spectra at frequencies ≥150 GHz to a lensed-ΛCDM model that includes dust and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r), using a prior on the frequency spectral behavior of polarized dust emission from previous Planck analysis of other regions of the sky. We find strong evidence for dust and no statistically significant evidence for tensor modes. We probe various model variations and extensions, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint. Finally, we present an alternative analysis which is similar to a map-based cleaning of the dust contribution, and show that this gives similar constraints. The final result is expressed as a likelihood curve for r, and yields an upper limit r_{0.05}<0.12 at 95% confidence. Marginalizing over dust and r, lensing B modes are detected at 7.0σ significance.

Abstract
INTRODUCTION Dissection of regional lymph nodes (RLNs) can lead to significant morbidity and a high prevalence of complications. Published guidance states that these procedures should be carried out by surgeons who are members of a specialist skin multidisciplinary team who carry out a combined minimum of 15 axillary/groin dissections per year. However, there is little evidence to guide this minimum figure of procedures. We report on the burden of service provision and prevalence of complications across the South West of England and Wales. METHODS A 12-month review of dissections of RLNs for skin cancer was undertaken covering five Plastic Surgery Units with a collective catchment of 8.4 million people. Detailed data were collected on patient demographics, pathology, timing of surgery, and prevalence of complications. RESULTS A total of 163 dissections were carried out. Forty-three per cent of patients experienced one or more complication. In that 12-month period, an average of 8 axillary/groin dissections was carried out per surgeon. A funnel plot demonstrated that the prevalence of complications for individual surgeons was within the limit of the plot but, in many cases, this was based only on a relatively small number of procedures per consultant. If surgeons carried out 10 procedures per year, the upper and lower limits on the plot were 73% and 11%, respectively. CONCLUSIONS Funnel plots can provide a useful guide as to whether the prevalence of complications for procedures for individual surgeons lies within acceptable limits. Based on these results, 10 procedures per consultant per year should be sufficient to enable meaningful assessment of the prevalence of complications.

Abstract
We report results from the BICEP2 experiment, a cosmic microwave background (CMB) polarimeter specifically designed to search for the signal of inflationary gravitational waves in the B-mode power spectrum around ℓ∼80. The telescope comprised a 26 cm aperture all-cold refracting optical system equipped with a focal plane of 512 antenna coupled transition edge sensor 150 GHz bolometers each with temperature sensitivity of ≈300 μK(CMB)√s. BICEP2 observed from the South Pole for three seasons from 2010 to 2012. A low-foreground region of sky with an effective area of 380 square deg was observed to a depth of 87 nK deg in Stokes Q and U. In this paper we describe the observations, data reduction, maps, simulations, and results. We find an excess of B-mode power over the base lensed-ΛCDM expectation in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ. Through jackknife tests and simulations based on detailed calibration measurements we show that systematic contamination is much smaller than the observed excess. Cross correlating against WMAP 23 GHz maps we find that Galactic synchrotron makes a negligible contribution to the observed signal. We also examine a number of available models of polarized dust emission and find that at their default parameter values they predict power ∼(5-10)× smaller than the observed excess signal (with no significant cross-correlation with our maps). However, these models are not sufficiently constrained by external public data to exclude the possibility of dust emission bright enough to explain the entire excess signal. Cross correlating BICEP2 against 100 GHz maps from the BICEP1 experiment, the excess signal is confirmed with 3σ significance and its spectral index is found to be consistent with that of the CMB, disfavoring dust at 1.7σ. The observed B-mode power spectrum is well fit by a lensed-ΛCDM+tensor theoretical model with tensor-to-scalar ratio r = 0.20_(-0.05)(+0.07), with r = 0 disfavored at 7.0σ. Accounting for the contribution of foreground, dust will shift this value downward by an amount which will be better constrained with upcoming data sets.

Abstract
OBJECTIVES Acral lentiginous melanoma (ALM) is a defined histopathological entity with peculiar clinical-pathological features and is the most common subtype of malignant melanoma in acral locations. The 5-year survival rate is lower than that for all cutaneous malignant melanoma overall (80.3% versus 91.3%). Controversy exists in the literature as to whether this worse prognosis is attributable to a more aggressive biological nature or to difficult-to-see sites and consequent advanced stage at the time of diagnosis. The main purpose of the study was to explore any prognostic difference according to upper limb or lower limb localizations, based on the hypothesis that upper limb localizations might receive attention sooner than lower limb localizations. PATIENTS AND METHODS A cohort longitudinal study was performed through a retrospective review of all patients consecutively referred to our Unit with histological confirmation of ALM. Data were collected from a 10 year period between 1996 and 2006 to allow determination of 5 year survival statistics. RESULTS Out of 87 patients included in the study, 32 were men (37%) and 55 were women 63%. The average number of months it took for patients to present was 62 months with a mode of 12 months. Overall 5 year survival was 80% and a multivariate analysis showed that the most reliable prognostic indicators are the Breslow's thickness and the margins of complete excision. When controlling the survival rates for Breslow thickness, the values were similar to the reported rates indicated in the recent literature for cutaneous malignant melanoma. CONCLUSIONS The higher aggressiveness of ALM was noticed to be attributable to a later stage and more advanced thickness at diagnosis. No significant difference was found between upper and lower limb localization in terms of prognosis.

Abstract
Data from literature suggest the possible use of probiotics as chemopreventive agents against colon cancer, but few investigations are available on their effects on gastric cancer proliferation. In our previous study, a specific Lactobacillus, strain L. paracasei IMPC2.1, was demonstrated to colonize the human gut and positively affect fecal bacteria and biochemical parameters. The aims of the present study were to investigate the effects of L. paracasei IMPC2.1, comparing them with those of Lactobacillus rhamnosus GG (L.GG), either as viable or heat-killed cells, on cell proliferation and apoptosis in a gastric cancer (HGC-27) and a colorectal cancer cell line (DLD-1). Both the gastric and colon cancer cells were sensitive to the growth inhibition and apoptosis induction by both viable or heat-killed cells from L. paracasei IMPC2.1 and L.GG. These findings suggest the possibility for a food supplement, based on dead probiotics, including L. paracasei IMPC2.1 cells, which could represent an effective component of a functional food strategy for cancer growth inhibition, with potential for cancer prevention.

Viral hepatitis reactivation has been widely reported in patients undergoing immunosuppressive therapy; however, few data are available about the risk of HBV and HCV reactivation in patients with inflammatory bowel disease, receiving immunosuppressive drugs. The aim of our study was to assess the prevalence of HBV and HCV infection in a consecutive series of patients with inflammatory bowel disease and to value the effects of immunosuppressive therapy during the course of the infection. Retrospective observational multicenter study included all consecutive patients with inflammatory bowel disease who have attended seven Italian tertiary referral hospitals in the last decade. A total of 5096 patients were consecutively included: 2485 Crohn's disease and 2611 Ulcerative Colitis. 30.5% and 29.7% of the patients were investigated for HBV and HCV infection. A total of 30 HBsAg positive, 17 isolated anti-HBc and 60 anti-HCV-positive patients were identified. In all, 20 patients with HBV or HCV infection received immunosuppressive therapy (six HBsAg+; four isolated anti-HBc+ and 10 anti-HCV+). One of six patients showed HBsAg+ and one of four isolated anti-HBc+ experienced reactivation of hepatitis. Two of six HBsAg patients received prophylactic therapy with lamivudine. Only one of 10 anti-HCV+ patients showed mild increase in viral load and ALT elevation. Screening procedures for HBV and HCV infection at diagnosis have been underused in patients with inflammatory bowel disease. We confirm the role of immunosuppressive therapy in HBV reactivation, but the impact on clinical course seems to be less relevant than previous reported.

Abstract
Randomized controlled trials (RCTs) are the gold standard method for developing evidence-based medicine in inflammatory bowel disease (IBD). Methodological problems in RCTs in IBD concern different aspects such as the definition of the study population due to the extreme variability of patients with IBD, the indices of disease activity, a clearly defined outcome, the environmental risk factors (i.e smoking behaviour) that may influence the randomization, the heterogeneous placebo rate of remission and the different statistical methods used to analyze the results. It is important that trials are designed efficiently, done well and complement clinical practice with a careful subject selection, standardization of disease activity indices, and precise outcome measurement in order to continue the improvement of the IBD research process.

Abstract
BACKGROUND The role of probiotics in the management of constipation is uncertain. AIMS To evaluate the effects of probiotic-enriched artichokes on treatment preference, symptom profile and short-chain fatty acid (SCFA) production in constipated subjects when compared with ordinary artichokes. METHODS Twenty constipated patients (3M/17F; 38.8 ± 14.4 years) were studied using a double-blind method and a computer-generated randomisation list. Each patient consumed 180 g per day of ordinary artichokes or artichokes enriched with Lactobacillus paracasei IMPC 2.1 for 15 days (daily dose of 2 × 10(10) CFU). Relief of symptoms was evaluated using a visual analogue scale. The stool consistency and symptom profile of patients were investigated using the Bristol stool form chart and the Gastrointestinal Symptom Rating Scale questionnaire (GSRS). SCFA production in faecal samples was evaluated using HPLC. RESULTS Eighty per cent of patients preferred probiotic-enriched artichokes to ordinary ones (P = 0.011). Satisfactory relief of symptoms was significantly higher (P = 0.0014) during the probiotic-enriched artichoke period. Bristol chart cluster scores were significantly higher (3.3 ± 1.2, 2.9 ± 1.3 2.2 ± 1.2, baseline, ordinary artichokes and probiotic-enriched ones, respectively; P = 0.009) and GSRS constipation was significantly lower (13.9 ± 0.9, 10.2 ± 0.8, 8.3 ± 0.9; P = 0.032) in the probiotic group compared with the baseline. As for SCFA production, propionic acid was significantly higher (2.2 ± 1.4, 2.1 ± 1.53, 1.5 ± 1.2; P = 0.035) in the probiotic group compared with baseline. CONCLUSION This trial shows a positive effect on symptoms in constipated patients after intake of probiotic-enriched artichokes.

Abstract
Chemoprevention by dietary constituents has recently emerged as a novel approach to control gastric cancer incidence. Over the past years, functional foods and food supplements, especially probiotics, have received much attention as potential dietary cancer prevention agents. The precise mechanisms by which these lactic cultures exert their antitumorigenic activities are not fully elucidated, but there is some evidence of their influence on cell proliferation and growth. Ornithine decarboxylase (ODC) and spermidine/spermine N1-acetyltransferase (SSAT) are the key enzymes involved in polyamine biosynthesis and catabolism, respectively. These polycationic compounds are significantly associated with cancer risk and represent a specific markers for neoplastic proliferation. The aim of this study was to investigate the effects of increasing concentrations of Lactobacillus rhamnosus strain GG (ATCC 53103) (L. GG) homogenate on polyamine biosynthesis and polyamine degradation as well as on resulting polyamine levels in HGC-27 human gastric cancer cells. The influence of this probiotic on cell proliferation was also evaluated. Administration of probiotic homogenate significantly reduced both ODC mRNA and activity as well as polyamine content and neoplastic proliferation. Besides, an increase in both SSAT mRNA and activity occurred after LGG administration in HGC-27. These data suggest that a nutritional component such as the probiotic L. GG could be proposed in an alternative approach to prevention of gastric cancer. This strategy could overcome the limitations due to a prolonged use of drugs and/or the occurrence of their adverse effects, and it could reasonably also start at a young age.
