Cell stress increases ATP release in NLRP3 inflammasome-mediated autoinflammatory diseases, resulting in cytokine imbalance.

Cell stress is implicated in triggering bouts of systemic inflammation in patients with autoinflammatory disorders. Blood monocytes from patients affected by NLRP3-mediated cryopyrin-associated periodic syndromes (CAPS) release greater amounts of IL-1β than monocytes from unaffected subjects. Here we show that stress lowers the threshold of activation; blood monocytes from CAPS patients maintain the high levels of secreted IL-1β (fivefold) and IL-18 (10-fold) when stimulated with 1,000-fold less LPS than that required for full IL-1β secretion in control subjects.

Folate-Cyclodextrin Conjugates as Carriers of the Platinum(IV) Complex LA-12.

Folic acid has emerged as an interesting cell-targeting moiety and a number of drugs have been conjugated to folate. In this context, new conjugates of β-cyclodextrins with folate have been synthesised as drug carriers to improve their selectivity for cells overexpressing the folic acid receptor. In particular, both 3- and 6-functionalised β-cyclodextrins, linked to the α- or γ-carboxylic group of folic acid, have been synthesised and fully characterised.

Blood pressure levels and control in Italy: comprehensive analysis of clinical data from 2000-2005 and 2005-2011 hypertension surveys.

This analysis is aimed to determine blood pressure (BP) levels and BP control rates in a large population of hypertensive patients in Italy. Data were taken from two large and inclusive cross-sectional surveys, which covered two distinct and subsequent time periods (2000-2005 and 2005-2011, respectively). Observational clinical studies and surveys, which reported average systolic/diastolic clinic BP levels, proportions of treated/untreated and controlled/uncontrolled patients, and prevalence of cardiovascular risk factors in hypertensive patients followed in either outpatient clinics, hypertension centres or general practice, were considered for the analyses.

Inflammation in arterial diseases.

The pathophysiology of some inflammatory arterial diseases (such as vasculitis, atherogenesis and aneurysms) has been widely investigated in the last decades. Among different soluble molecules, proinflammatory cytokines (such as TNF-α, IL-1 and IL-6) were shown to trigger critical pathways regulating these arterial diseases. Together with these cytokines, chemokines were also associated with endothelial dysfunction and intima injury in arterial diseases.

Atypical presentations of bullous pemphigoid: Clinical and immunopathological aspects.

Bullous pemphigoid may occur in extremely variegated manners, misleading even experienced dermatologists. Indeed the type and/or distribution of lesions may be unusual. Furthermore, there may be an atypical demographic profile of patients, a different clinical course and a different responsiveness to therapy.

Lung function testing in COPD: when everything is not so simple.

Combined pulmonary fibrosis and emphysema is a condition occurring mainly in male smokers, presenting different lung mechanics and gas exchange abnormalities than emphysema or pulmonary fibrosis alone. We report the case of an elderly man, former heavy smoker, who presented with progressive exertional dyspnea for 1 year. Lung function tests showed near normal spirometry and lung volumes but marked reduction of diffusing capacity for carbon monoxide and even more nitric oxide.

Treatment with recombinant tissue plasminogen activator (r-TPA) induces neutrophil degranulation in vitro via defined pathways.

Thrombolysis is recommended for reperfusion following acute ischemic stroke (AIS), but its effects on stroke-associated injury remain to be clarified. Here, we investigated the effects of recombinant tissue plasminogen activator (r-tPA) on neutrophil pathophysiology in vitro and in a case-control study with AIS patients submitted (n=60) or not (n=30) to thrombolysis. Patients underwent radiological and clinical examination as well as blood sampling at admission and after 1, 7 and 90days.

Helicobacter pylori infection and eye diseases: a systematic review.

The connection between Helicobacter pylori (Hp) infection and eye diseases has been increasingly reported in the literature and in active research. The implication of this bacterium in chronic eye diseases, such as blepharitis, glaucoma, central serous chorioretinopathy and others, has been hypothesized. Although the mechanisms by which this association occurs are currently unknown, this review describes shared pathogenetic mechanisms in an attempt to identify a lowest common denominator between eye diseases and Hp infection.

The use of semi-quantitative ultrasound elastosonography in combination with conventional ultrasonography and contrast-enhanced ultrasonography in the assessment of malignancy risk of thyroid nodules with indeterminate cytology.

Background: The pre-surgical selection of thyroid nodules with indeterminate cytology (Thy 3 according to British Thyroid Association) after fine-needle aspiration biopsy (FNAB) is currently required in order to reduce unnecessary total thyroidectomy. The objective of our study was to use a surgical series of Thy 3 nodules to evaluate the predictive role of ultrasound elastosonography (USE) and contrast-enhanced ultrasonography (CEUS) in pre-surgical diagnoses of malignancy.

Subjects And Methods: We enrolled 63 patients with Thy 3 nodules in which cytological-histological correlation was available.

Dienogest in women with persistent endometriosis-related pelvic pain during norethisterone acetate treatment.

Objective: To evaluate patient satisfaction at 6-months dienogest (DNG) treatment in women with symptomatic rectovaginal endometriosis who had pain persistence and were unsatisfied after 6-months of norethisterone acetate (NETA) therapy.

Study Design: This 24-weeks pilot open-label prospective study enrolled 25 women. The main outcome was the degree of patient satisfaction measured by using a Likert scale.

Progestin-only contraception compared with extended combined oral contraceptive in women with migraine without aura: a retrospective pilot study.

Objective: To evaluate the effect of a desogestrel progestogen-only pill (POP) compared to continuous combined oral contraception (COC) on migraine patterns in women with migraine without aura.

Study Design: A retrospective analysis of prospective headache charts from migrainous women who used the POP or COC in our clinic between July 2009 and July 2013. The quality and quantity of migraine attacks and use of medications were evaluated at three and six months.

Clinical Outcomes of Castration-resistant Prostate Cancer Treatments Administered as Third or Fourth Line Following Failure of Docetaxel and Other Second-line Treatment: Results of an Italian Multicentre Study.

Background: The availability of new agents (NAs) active in patients with metastatic castration-resistant prostate cancer (mCRPC) progressing after docetaxel treatment (abiraterone acetate, cabazitaxel, and enzalutamide) has led to the possibility of using them sequentially to obtain a cumulative survival benefit.

Objective: To provide clinical outcome data relating to a large cohort of mCRPC patients who received a third-line NA after the failure of docetaxel and another NA.

Design, Setting, And Participants: We retrospectively reviewed the clinical records of patients who had received at least two successive NAs after the failure of docetaxel.

New 8-hydroxyquinoline galactosides. The role of the sugar in the antiproliferative activity of copper(II) ionophores.

8-Hydroxyquinoline derivatives and their metal complexes have recently awakened interest as promising therapeutic agents in cancer therapy. We have previously synthesized and evaluated glucoconjugated 8-hydroxyquinolines as copper ionophores activated by β-glucosidases. In order to further evaluate the crucial role of the sugar, we designed and synthesized a series of new galactoconjugates of 8-hydroxyquinolines and investigated their biological properties in comparison with the 8-hydroxyquinoline analogs.

Relapsing pityriasis rosea.

To assess the prevalence of relapses of pityriasis rosea (PR), a retrospective cohort study investigated all PR cases diagnosed in Genoa between 2000 and 2013 and followed them up to today. Of 570 cases, 21 (3.7%) relapsed.

New risks from ancient food dyes: cochineal red allergy.

This study reports an unusual case of IgE-mediated hypersensitivity to Cochineal red or Carmine red, a coloring agent of natural origin. Although the risk of anaphylactic reactions is well known, since the nineties the use of this additive seems to be nowadays on the rise. The problem of labeling of additives used in handmade food products is highlighted.

H19 long noncoding RNA controls the mRNA decay promoting function of KSRP.

Long noncoding RNAs (lncRNAs) interact with protein factors to regulate different layers of gene expression transcriptionally or posttranscriptionally. Here we report on the functional consequences of the unanticipated interaction of the RNA binding protein K homology-type splicing regulatory protein (KSRP) with the H19 lncRNA (H19). KSRP directly binds to H19 in the cytoplasm of undifferentiated multipotent mesenchymal C2C12 cells, and this interaction favors KSRP-mediated destabilization of labile transcripts such as myogenin.

Public biobanks: calculation and recovery of costs.

A calculation grid developed by an international expert group was tested across biobanks in six countries to evaluate costs for collections of various types of biospecimens. The assessment yielded a tool for setting specimen-access prices that were transparently related to biobank costs, and the tool was applied across three models of collaborative partnership.

IRIS: methodological assessment of psychopathological disease in a cohort of hirsute women.

Background: Hirsutism in females can be a source of considerable psychological distress and a threat to female identity. The aim of our study was to evaluate a possible relationship between facial, total body hair involvement and physical, mental and social well-being during 12 months of follow-up and treatment. Both objective and subjective methods of evaluating hirsutism were used: the Ferriman-Gallwey (FG) scoring method and the questionnaires General Health Questionnaire (GHQ)-12, Polycystic Ovary Syndrome Questionnaire (PCOSQ) and SF-12.

Pharmacokinetic and pharmacodynamic profile of dronedarone , a new antiarrhythmic agent for the treatment of atrial fibrillation.

Introduction: Atrial fibrillation (AF) is the most common arrhythmia and is associated with increased morbidity and mortality. Dronedarone is a recent antiarrhythmic drug that has been developed for treatment of AF, with electrophysiological properties similar to amiodarone but with a lower incidence of side effects.

Areas Covered: This review evaluates the efficacy, safety, tolerability and side effects of dronedarone in the treatment of AF.

Overcoming resistance to BRAF inhibition in BRAF-mutated metastatic melanoma.

Almost 50% of metastatic melanoma patients harbor a BRAF(V600) mutation and the introduction of BRAF inhibitors has improved their treatment options. BRAF inhibitors vemurafenib and dabrafenib achieved improved overall survival over chemotherapy and have been approved for the treatment of BRAF-mutated metastatic melanoma. However, most patients develop mechanisms of acquired resistance and about 15% of them do not achieve tumor regression at all, due to intrinsic resistance to therapy.

Genetic deletion of the adaptor protein p66Shc increases susceptibility to short-term ischaemic myocardial injury via intracellular salvage pathways.

Aims: Several intracellular mediators have been implicated as new therapeutic targets against myocardial ischaemia and reperfusion injury. However, clinically effective salvage pathways remain undiscovered. Here, we focused on the potential role of the adaptor protein p66(Shc) as a regulator of myocardial injury in a mouse model of cardiac ischaemia and reperfusion.
