Missing Persons’ Report! Where are the Transgender Characters in Children’s Picture Books?

When ruminating on the factors that impact early childhood education, one invariably reflects on the topic of how curriculum represents (or fails to represent) issues of gender, specifically with regard to how gender is portrayed within the selection of classroom picture books. In such ruminations, many questions emerge regarding the specific role reading curriculum plays as it relates to gender

Neighbourhood size and neighbourhood frequency effects in the recognition of Italian written words

2010 - 2011The present research investigates neighbourhood size and neighbourhood frequency effects in recognition of Italian written words. Neighbourhood size is the number of words that may be generated by changing one letter of the target word, preserving letter positions; neighbourhood frequency refers to the relationship between the frequencies of neighbours and the frequency of the stimulus word (Grainger, O’Regan, Jacobs & Segui, 1989). By extending the studies on Italian non words of Arduino & Burani (2004) and Mulatti, Peressotti & Job (2007) to Italian five-letter words, four experiments were carried out in order to test the neighbourhood size and the neighbourhood frequency effects, as well as the possible interaction between them. We have used, as experimental tasks, the simple lexical decision, the word and nonword naming and the lexical decision with unmasked orthographic priming.[edited by author]X n.s

Association of bovine papillomavirus type 2 (BPV-2) and urinary bladder tumours in cattle from the Azores archipelago

Copyright (c) 2010 Elsevier Ltd. All rights reserved.Urinary bladder tumours in cattle are caused by chronic ingestion of bracken fern and BPV-1/2 infection. The objective of the present study was to assess if BPV-2 was present in urinary bladder lesions from cattle with chronic enzootic haematuria (CEH) from the Azores archipelago (Portugal), in order to gain further information regarding the epidemiologic distribution of this virus. Samples were analysed using PCR specific primers for BPV-2 DNA and an immunohistochemistry for BPV E5 oncoprotein detection. We found a 28% incidence rate of BPV-2 DNA in different types of tumours and cystitis cases (13 out of 46 samples). Tested positive samples for PCR were also positive for the viral E5 oncoprotein; protein immunolabeling was mainly detected within the cytoplasm of urothelial cells, displaying a juxtanuclear distribution. This is the first report of BPV-2 detection in urinary bladder tumours associated with CEH in cattle from the Azores archipelago.Direcção Regional da Ciência e Tecnologia, Governo dos Açores, Portugal; Università degli Studi di Napoli Federico-II (Italia); CIRN (Centro de Investigação em Recursos Naturais, Universidade dos Açores) (Portugal)

Detection of bovine papillomavirus type 2 in the peripheral blood of cattle with urinary bladder tumours: possible biological role

Bovine papillomavirus type 2 (BPV-2) infection has been associated with urinary bladder tumours in adult cattle grazing on bracken fern-infested land. In this study, we investigated the simultaneous presence of BPV-2 in whole blood and urinary bladder tumours of adult cattle in an attempt to better understand the biological role of circulating BPV-2. Peripheral blood samples were collected from 78 cattle clinically suffering from a severe chronic enzootic haematuria. Circulating BPV-2 DNA was detected in 61 of them and in two blood samples from healthy cows. Fifty of the affected animals were slaughtered at public slaughterhouses and neoplastic proliferations in the urinary bladder were detected in all of them. BPV-2 DNA was amplified and sequenced in 78% of urinary bladder tumour samples and in 38.9% of normal samples as a control. Circulating episomal BPV-2 DNA was detected in 78.2% of the blood samples. Simultaneous presence of BPV-2 DNA in neoplastic bladder and blood samples was detected in 37 animals. Specific viral E5 mRNA and E5 oncoprotein were also detected in blood by RT-PCR and Western blot/immunocytochemistry, respectively. It is likely that BPV-2 can persist and be maintained in an active status in the bloodstream, in particular in the lymphocytes, as a reservoir of viral infection that, in the presence of co-carcinogens, may cause the development of urinary bladder tumours

Colonic Lipoma Causing Bowel Intussusception: An Up-to-Date Systematic Review

Lipoma colónico; CirugíaLipoma colònic; CirurgiaColonic lipoma; SurgeryBackground: Colonic lipomas are rare and can sometimes cause intussusception. The aim of this review was to define the presentation and possible management for colocolic intussusception caused by colonic lipomas. Methods: A systematic search for patients with colocolic intussusception caused by colonic lipoma, including all available reports up to 2021. Epidemiological, clinical, laboratory, and instrumental data and details about the treatments performed were gathered. Results: Colocolic intussusception caused by lipoma is more frequent in women (57%), occurring between 40 and 70 years of age. Up to 83% of patients report abdominal pain, followed by constipation (18%), rectal bleeding (16%), and diarrhea (12%), with abdominal tenderness (37%), and distension in 16%, whereas 24% have a negative exploration. CT (72%) and colonoscopy (62%) are more commonly able to diagnose the entity. The most common location of intussusception is the transverse colon (28%). The surgical operation varies according to the site. The average dimensions of the lipoma are 59.81 × 47.84 × 38.9 mm3. Conclusions: A correct preoperative diagnosis of colonic lipoma causing intussusception might not be easy. Despite nonspecific clinical and laboratory presentation, cross-sectional imaging can help differential diagnosis. Surgical treatment depends on the localization.This research received no external funding

Assessment of liver stiffness in patients with HCV and mixed cryoglobulinemia undergoing rituximab treatment.

INTRODUCTION: Mixed cryoglobulinemia (MC) is a HCV-related lymphoproliferative disorder generally associated with advanced liver disease. Liver stiffness has been significantly correlated with histopathological stage of fibrosis. Moreover, it was influenced by necroinflammatory activity. Rituximab (RTX) is a chimeric anti-CD20 monoclonal antibody inducing transient B lymphocytes depletion that was shown to be useful and safe in the majority of HCV MC patients, leading also to improvement of cirrhotic syndrome. Aim of this study was to evaluate the modifications of liver stiffness following RTX treatment in HCV-related MC patients. MATERIALS AND METHODS: Fourteen consecutive patients (10 F, 4 M; mean age 60.43 ± 43) with HCV-related chronic hepatitis (n = 10) or cirrhosis (n = 4) and MC, eligible for RTX treatment, were prospectively enrolled. Intravenous injection of 1 g of RTX was performed at day 0 and at day 15. Assessment of stiffness was carried out by Fibroscan(®) (Echosens, Paris-France) at baseline, 15 days after the first infusion, and at month 1, 3 and 6 after therapy. RESULTS: MC symptoms significantly improved during the study, especially during the first 3 months. Liver stiffness observed 3 months after treatment was significantly reduced when compared with pre-treatment values (p = 0.01). This difference disappeared after 6 months of follow-up. Cytofluorimetric analysis showed a decrease of CD19+ peripheral blood cells, with the nadir at month 3 after therapy and B cell compartment reconstitution after 6 months. CONCLUSION: This study, for the first time showed that RTX-treatment in HCV-related MC induces a reduction of liver stiffness that is strictly associated with the B-cell depletion

765 Is acute response to calcium sensitizers drugs predictive of response to cardiac contractility modulation in NYHA IV patients?

Abstract A 53-years old man presented to our institution with a diagnosis of decompensated heart failure NYHA Class IV. He had a history of ischaemic heart disease with severe biventricular dysfunction, diabetes, hypertension, dyslipidaemia, advanced chronic kidney disease, previous explanation of dual-chamber implantable electronic device (ICD) due to endocarditis and subsequent implantation of subcutaneous ICD in primary prevention. Home therapy included uptitrated angiotensin-converting enzyme inhibitor, β-blocker, loop-diuretic, spironolactone, acetylsalicylic acid, and oral hypoglycemics. Clinical examination showed signs and symptoms of systemic and pulmonary congestion with pleural effusion and ascites. Echocardiography revealed diffuse left ventricular (LV) hypokinesis with an ejection fraction (EF) of 25%, severe right ventricular dysfunction and increased filling pressures. He was treated with high dose of i.v. diuretics with mild improvement of dyspnoea. However, haemodynamic stability was labile with worsening of symptoms as soon as mild down-titration of iv diuretics was attempted. Levosimendan, a calcium-sensitizer inodilator, indicated for short-term treatment of acutely decompensated severe chronic heart failure (HF), was administered with good clinical response. Thus, we thought that the patient could have benefited from contractility modulation therapy (CCM) which acts on intramyocardial calcium handling. CCM is a novel therapeutic option for patients with classes III–IV HF with EF ≥ 25% to ≤ 45% and narrow QRS complex that acts on intramyocardial calcium-handling. CCM proved effective in alleviating symptoms, improving exercise tolerance and quality of life, and reducing hospitalization rates in HF. It improves myocardial contractility, reverses the foetal myocyte gene program associated with HF and facilitates cardiac reverse remodelling. Therefore, an Optimizer Smart System (Impulse Dynamics) was implanted. Two pacing electrodes were placed on the interventricular septum in apical and mid-septal position, respectively. The leads were connected to a pulse-generator in a right pectoral pocket. In the following days, we observed a progressive improvement in clinical status, with gradual resolution of peripheral oedema, dyspnoea and fatigue and significant weight loss. Six-month echocardiography showed a stable value of EF and significant improvement in stroke volume (35.2 ml from 24.8 ml at baseline). The patient did not undergo further hospitalization for decompensated HF and was in stable ambulatory NYHA Class IV. We believe CCM is an option in patients with advanced HF in which avoiding recurrent hospitalizations, with their overt increase mortality, is often a challenging therapeutic goal. 765 Figur

Long-term effect of HCV eradication in patients with mixed cryoglobulinemia: A prospective, controlled, open-label, cohort study

Limited data are available about the efficacy of antiviral treatment in hepatitis C virus (HCV)-associated mixed cryoglobulinemia (MC), especially concerning the long-term effects of HCV eradication. The aim of this study was to evaluate the influence of MC on the virological response and the long-term effects of viral eradication on MC. We prospectively enrolled 424 HCV+ patients belonging to the following groups: MCS-HCV (121 patients with symptomatic MC); MC-HCV (132 patients with asymptomatic MC); HCV group (158 patients without MC). Peg-IFN+RBV treatment was administered according to standard protocols. Post-treatment follow-up ranged from 35 to 124 months (mean: 92.5 months). A significant difference was observed in the rate of sustained virological response (SVR) between HCV and both MC-HCV (p=0.009) and MC-HCV+MCS-HCV (p=0.014) groups. Multivariate logistic regression analysis identified cryoglobulinemia as an independent prognostic factor of non-response. The clinical-immunological response in MCS-HCV correlated with the virological one. All patients with SVR also experienced a sustained clinical response, either complete or partial. In the majority of SVR patients all MCS symptoms persistently disappeared (36 patients, 57%); in only 2 (3%) did definite MCS persist. All virological non-responders were also clinical non-responders, in spite of a transient improvement in some cases. No evolution to lymphoma was observed. For the first time we have evaluated both the effects of IFN-based therapy on HCV patients with or without MC, and with or without symptoms, and the long-term effects of viral eradication on MC. MC was shown to be a negative prognostic factor of virological response. HCV clearance led to persistent resolution or improvement of MC syndrome, strongly suggesting the need for a next generation of highly effective antiviral drugs
