In this work, amino functionalized CdSe-silica core-shell nanoparticles (NH2-CdSe@SiO2 NPs) were constructed as probe to detect picric acid (PA). The CdSe QDs were embedded in SiO2 nanoparticles and modified with amino groups on the surface. The nitro explosives are electron deficient in nature, which will have stronger affinity for amines and resulted in fluorescence quenching of quantum dots. It was proved that this strategy is selective, easy and sensitive enough for sensing PA with a detection limit of 0.5 × 10-7 M. V.Few cases of late onset neutropenia after RITUXIMAB treatment (LONART) have been reported in patients with neuroinflammatory disorders. We conducted a retrospective analysis of patients treated with RITUXIMAB for neuromyelitis optica spectrum disorders (NMOSD), MOG-antibody-associated disease (MOGAD) and multiple sclerosis (MS) at the Toulouse University Hospital from November 2007 to October 2019. Ten patients with LONART were identified in a total of 385 patients 4/25 were MOGAD patients, 2/20 were NMOSD patients and only 4/340 were MS patients (p  less then  0,05). Six required intravenous antibiotics whereas four were asymptomatic. Eight patients received new infusions of RITUXIMAB after resolution of their neutropenia. Neutropenia recurred in one patient. Obsessive-compulsive symptoms (OCS) commonly occur in the course of schizophrenia. The aim of this study was to investigate the rate of obsessive-compulsive disorder (OCD) in patients with chronic schizophrenia and evaluate lifetime correlates of the comorbidity. Subjects were clinically stable patients with chronic schizophrenia (n = 320). Patients having comorbid OCD and those without OCD were compared in terms of symptoms dimensions and cognitive function. OCD was found in 20.6 % of subjects. Earlier age at onset, male gender, higher level of education, comorbid panic disorder, and specific phobia were associated with comorbid OCD. In terms of lifetime symptoms, depression (p = 0.001) and anxiety (p = 0.014) showed significant association with the comorbidity, which corroborates with our previous study findings regarding OCD in bipolar disorder. In addition, decreased emotional response (p = 0.016), less formal thought disorder (p = 0.007), and less prodromal impairment (p = 0.005) were independently associated with the comorbidity. The OCD group showed better performance in working memory domain (p = 0.027) while other cognitive domains did not show any significant difference between the two groups. Association of OCSs with depressive symptoms and other comorbid anxiety disorders seems to be a common finding across schizophrenia and bipolar disorder. This study also suggests that comorbidity of OCD in schizophrenia is associated with less impairment of thought process and cognitive function throughout the disease course. The key to the provision of appropriate care to consumers experiencing mental disorders is to ensure that resources are appropriate to their needs. A model that streams mental health clinicians into case management, care coordination and key work streams would be helpful for services to provide appropriate case management support to consumers enrolled in their program. The neural gut-brain axis consists of viscerosensory and autonomic motor neurons innervating the gastrointestinal (GI) tract. Sensory neurons transmit nutrient-related and non-nutrient-related information to the brain, while motor neurons regulate GI motility and secretion. Previous research provides an incomplete picture of the brain nuclei that are directly connected with the neural gut-brain axis, and no studies have thoroughly assessed sensory-motor overlap in those nuclei. Our goal in this study was to comprehensively characterize the central sensory and motor circuitry associated with the neural gut-brain axis linked to a segment of the small intestine. We injected a retrograde (pseudorabies; PRV) and anterograde (herpes simplex virus 1; HSV) transsynaptic viral tracer into the duodenal wall of adult male rats. Immunohistochemical processing revealed single- and double-labeled cells that were quantified per nucleus. We found that across nearly all brain regions assessed, PRV + HSV immunoreactive neurons comprised the greatest percentage of labeled cells compared with single-labeled PRV or HSV neurons. These results indicate that even though sensory and motor information can be processed by separate neuronal populations, there is neuroanatomical evidence of direct sensory-motor feedback in the neural gut-brain axis throughout the entire caudal-rostral extent of the brain. This is the first study to exhaustively investigate the sensory-motor organization of the neural gut-brain axis, and is a step toward phenotyping the many central neuronal populations involved in GI control. V.BACKGROUND Rural-dwellers have poorer cancer outcomes than urban counterparts, for reasons which are unclear. At healthcare institution level, poorer access to investigations and different clinical decision-making by rural primary healthcare practitioners (PCPs) could be important. Trichostatin A AIM To compare access to investigations, attitudes to cancer diagnosis and clinical decision-making between rural and urban PCPs. SETTING A vignette-based cross-sectional survey of rural and urban PCPs in 20 European countries. METHODS Data on PCPs' decision-making and attitudes to cancer diagnosis were based on clinical scenarios. Comparisons were made using tests of proportion, univariable and multivariable binary logistic regression. RESULTS Of the 1779 PCPs completing the survey 541 30.4 %) practiced rurally. Rural PCPs had significantly less direct access to all investigative modalities ultrasound; endoscopy; x-ray and advanced screening (all p less then 0.001). Rural PCPs were as likely as urban PCPs to take diagnostic action (investigation and/or referral) at the index consultation in all four clinical vignettes ((OR, 95 % CI) for lung 0.90, 0.72-1.12; ovarian 0.95, 0.75-1.19; breast 0.87, 0.69-1.09; colorectal 0.98, 0.75-1.30). Rural PCPs were less likely to refer to a specialist at the index consultation for ovarian cancer (OR 0.71 95 % CI 0.51-0.99). Rural PCPs were significantly more likely to report that their patients faced barriers to accessing specialist care, but practitioners did not report greater difficulties making specialist referral than their urban counterparts CONCLUSIONS European rural PCPs report poorer access to investigations but are at least as likely as urban PCPs to investigate or refer patients that might have cancer at the index consultation. BACKGROUND Cancers comprise a significant proportion of urologic workload. The epidemiology of prostate and renal cancers is well described. We report the incidence, survival and predictors of survival for non-prostate, non-renal urologic cancers between 1977 and 2013. METHODS All patients in the South Australian Cancer Registry diagnosed with bladder, testis, penis, renal pelvis, ureteric and other male genital organ cancers between 1977 and 2013 were included. Demographic data included age, sex, year of diagnosis, grade, and metropolitan/rural status. Changes in incidence, survival and predictors of survival are reported for each cancer type. RESULTS Between 1977 and 2013, bladder cancer was the most common of the studied urologic cancers (6465/9317). Age standardized incidence rate for bladder cancer decreased from 15.6-9.0 per 100,000 in 2013 (Annual Percentage Change (APC) -0.97 %, p less then 0.05 %). Between 1977 and 2013 mortality has increased in patients with bladder cancer (HR 1.01 per year, p = 0.004). Testicular cancer diagnoses increased from 1.7 to 4.7 per 100,000 through 1977-2012 (APC 2.41 %, p less then 0.05 %). Survival has increased (HR 0.95 per year, p less then 0.001). Incidence of penile cancers has increased from 0.23 to 0.46 per 100,000 (APC 2.8 %); Penile cancer survival has remained static (HR 1.02 p = 0.23).Five and ten year survival estimates were highest for testicular cancer - 93.4 % and 91.1 % respectively; and lowest for renal pelvis - 36.3 % and 24.6 %. CONCLUSION The incidence of non-prostate, non-renal urologic cancers remains low and stable. The age-standardized incidence of testicular cancer has increased whilst there has been a decline in the age-standardized incidence of bladder cancer. Bladder cancer survival has decreased since the 1970s. Crown All rights reserved.BACKGROUND Herpes zoster (HZ) and herpes zoster ophthalmicus (HZO) are common and debilitating diseases. There is no consensus in the literature whether HZ and HZO exhibit seasonal patterns. OBJECTIVES To determine whether HZ and HZO are seasonal. STUDY DESIGN All patients in the OptumLabs® Data Warehouse (OLDW), a longitudinal, insurance claims database with de-identified lives between January 1, 2006 and December 31, 2017 with 365 days or more of continuous enrollment were considered in the study. The database was queried for patients reporting a new ICD-9/ICD-10 code for HZ or HZO and monthly counts of each administrative code were modeled using Morelet wavelets and analyzed for annual periodicity using Fisher's g test. RESULTS There were a total of 513,911 new cases of HZ during this time period; 40,166 cases (7.8 %) were reported as HZO. Administrative coding for new cases of HZ exhibited annual periodicity (P less then .001) with a peak in the summer. No periodicity was evident for HZO. CONCLUSIONS These results contribute to a growing body of evidence suggesting that HZ may be seasonal and help characterize the epidemiology of this common, painful disease. How is auditory emotional information processed? The study's aim was to compare cerebral responses to emotionally positive or negative spoken phrases matched for structure and content. Twenty participants listened to 198 vocal stimuli while detecting filler phrases containing first names. EEG was recorded from 128 sites. Three event-related potential (ERP) components were quantified and found to be sensitive to emotional valence since 350 ms of latency. P450 and late positivity were enhanced by positive content, whereas anterior negativity was larger to negative content. A similar set of markers (P300, N400, LP) was found previously for the processing of positive versus negative affective vocalizations, prosody, and music, which suggests a common neural mechanism for extracting the emotional content of auditory information. SwLORETA applied to potentials recorded between 350 and 550 ms showed that negative speech activated the right temporo/parietal areas (BA40, BA20/21), whereas positive speech activated the left homologous and inferior frontal areas. Pathogenic bacteria secrete virulence factors that interact with the human host to establish infections. The human immune system evolved multiple mechanisms to fight bacterial invaders, including immune proteases that were demonstrated to contribute crucially to antibacterial defense. Here we show that granzyme B degrades multiple secreted virulence mediators from Listeria monocytogenes, Salmonella typhimurium, and Mycobacteria tuberculosis. Pathogenic bacteria, when infected in the presence of granzyme B or granzyme-secreting killer cells, fail to grow in human macrophages and epithelial cells owing to their crippled virulence. A granzyme B-uncleavable mutant form of the major Listeria virulence factor, listeriolysin O, rescued the virulence defect in response to granzyme treatment. Hence, we link the degradation of a single factor with the observed decrease in virulent bacteria growth. Overall, we reveal here an innate immune barrier function of granzyme B by disrupting bacterial virulence to facilitate bacteria clearance by bystander immune and non-immune cells.
