DermaSilk in long-term control of infantile atopic dermatitis: a double blind randomized controlled trial.
No full textAtopic dermatitis is a chronic inflammatory disease characterized by severe itching, skin dryness, blistering and remittent-relapse course. The critical feature is a skin barrier dysfunction that leads to epidermal inflammation and to bacterial superinfection. The aim of our study is to assess the usefulness of DermaSilk in reducing dermatitis relapses, in infants affected by atopic dermatitis, previously treated with topical corticosteroid and, if needed, with antibiotics.
METHODS:
This is a double blind randomized study involving 22 infants, aged 4 to 18 months, affected by atopic dermatitis. Disease severity has been evaluated by the SCORAD Index. To achieve a complete remission, acute phases were managed following international guidelines. Subsequently, infants were randomized to either wear a set of DermaSilk body and tights (group A), or wear clothes in pure cotton (group B) for 24 months with the exception of the warmer months (from mid-May to mid-September).
RESULTS:
The use of topical steroid per month was significantly lower in the DermaSilk group compared to the cotton group (P=0.006). The subjective evaluation reflecting itching reduction was also statistically significant (P=0.014).
CONCLUSION:
This study shows that DermaSilk products can reduce relapses in infants with eczema during the maintenance phase and play a pivotal role in itching control, improving the quality of life of children and their family
Levels of circulating TNF-related apoptosis-inducing ligand in celiac disease
No full textIt has previously been demonstrated that the circulating levels of TNF-related apoptosis-inducing ligand (TRAIL) are significantly lower in patients with type 1 diabetes (T1D) than in normal age- and gender-matched controls. Since celiac disease (CD) is often associated with T1D, a retrospective study was performed to analyze the sera of a cohort of pediatric subjects: i) patients with CD at onset (n=100); ii) patients with potential CD (n=45); iii) patients with CD associated with other auto-immune diseases (n=17); and iv) patients with eosinophilic esophagitis (n=15). Among the patients with CD, 49 were also analyzed after six months on a gluten-free diet, while data were also available for 13 patients after one year on a gluten-free diet. No significant differences were found in the circulating levels of TRAIL between the patients with CD and the patients with either eosinophilic esophagitis or potential CD. Patients with CD associated with other auto-immune diseases showed significantly lower levels of TRAIL when compared with patients with CD alone. The gluten-free diet did not significantly modify the levels of circulating TRAIL at 6 or 12 months. Thus, although T1D and CD share common immunological features, the circulating levels of TRAIL show a significant difference between the two pathologies, and do not appear to be modulated in CD
Acute cardiovascular changes in women undergoing in vitro fertilisation (IVF), a systematic review and meta-analysis
Full text linkObjectives: Ovarian stimulation during fertility treatment leads to profound maternal physiological changes. Women undergoing in vitro fertilisation (IVF) may be at an increased risk of future cardiovascular morbidity, though little is known about the effects on maternal cardiovascular function. We aim to systematically review whether IVF treatment is associated with changes in maternal haemodynamic parameters, and the effects of different protocols. Study Design: A systematic review and meta-analysis of English language studies identified on Medline and EMBASE database, between 1978, to 2019. Search terms: IVF, maternal haemodynamics, and cardiovascular. Studies reporting on ovulation induction, intrauterine insemination, and oocyte donation were excluded. Methodological quality was assessed by using the adapted Critical Appraisal Skills Programme (CASP) checklist. A meta-analysis was conducted for blood pressure and heart rate on patients undergoing the long GnRH agonist protocol according to Cochrane guidelines. We considered four time points in the IVF cycle, in chronological order: pre-treatment, pituitary down regulation, peak oestradiol and the luteal phase. Results: Nine suitable studies were identified; four fulfilled the criteria for meta-analysis. Two studies measuring heart rate found a significant increase in heart rate from pituitary down-regulation to peak estradiol levels, which was supported by the meta-analysis (3.78 ± 2.18 (p= < 0.0001)). Three studies reported a significant decrease in blood pressure from baseline, with those suitable for meta-analysis showing a significant decrease in mean arterial pressure (-2.08 ± 1.79 (p= < 0.0001)). Cardiac functional changes were reported for all studies and the changes depended on the type of protocol used. Conclusions: In Vitro Fertilisation leads to acute changes in maternal haemodynamics at different time points of the stimulation protocol. We found an increase in heart rate from pituitary down-regulation to peak estradiol levels and a significant decrease in blood pressure from baseline or pituitary down-regulation to the luteal phase. Cardiac functional changes were reported for all studies on the agonist protocol, but no significant changes were found using the antagonist protocol. It remains unclear as to whether these acute changes were associated with pregnancy complications or chronic cardiovascular sequelae
TRAIL-based therapeutic approaches for the treatment of pediatric malignancies
No full textTumor necrosis factor-related apoptosis inducing ligand (TRAIL) is a pro-apoptotic ligand that has shown the exquisite ability to trigger extrinsic apoptosis in various types of cancer cells without significant toxicity toward normal cells, when compared to other pro-apoptotic ligands such as tumor necrosis factor (TNF) or Fas ligand. Consequently, TRAIL-based therapies aim to trigger apoptosis in cancer cells by providing the soluble TRAIL or monoclonal antibodies targeting the death receptors TRAIL-R1 or TRAIL-R2. In this review, we start by highlighting the relevance of the tumor microenvironment in tumor development and elimination. We then address conventional and targeted therapeutic approaches for cancer treatment, highlighting the mechanisms involved or targeted. We describe the extrinsic and intrinsic pro-apoptotic pathways of TRAIL, together with the evidences for its pro-survival signaling, and with the relevance of these pathways in therapy. Possible mechanisms of resistance to TRAIL-induced apoptosis are highlighted (i.e. c-FLIP, Bcl-2, IAPs, p53, NF-B) and the rationale for the combined administration of TRAIL with drugs targeting these mechanisms is provided. Preclinical data are reported and show encouraging evidences for TRAIL consideration in pediatric malignancies (i.e., leukemia, lymphomas, neuroblastoma, osteosarcoma, medulloblastoma). Clinical trials of TRAIL-based therapies on the overall population are in phase I or II, and we put particular focus on the pediatric population, on which only few trials have been conducted or are ongoing. Finally, we consider emerging cellular therapies based on TRAIL, such as TRAIL-engineered mesenchymal stem cells or 'inflammatory' dendritic cells. © 2013 Bentham Science Publishers
Review of the scientific literature on the health of the Roma and Sinti in Italy.
No full textBACKGROUND: Roma and Sinti in Italy are excluded from the rest of society, often live in precarious housing conditions and have poor access to health services. In Italy, the Roma and Sinti minority (.3% of the overall population) is scarcely represented if compared with other European countries.
METHODS: To establish what is known and how Roma and Sinti health is studied in Italy, we conducted a review of the scientific literature, including articles published between 2000 and 2010, found in Medline, Embase and Web of Science.
RESULTS: We analyzed 15 relevant articles out of 32 references. Four papers describe rare autosomal recessive disorders. Four illustrate outbreaks of measles. The remaining papers describe health conditions suffered by this minority. All but two, however, are based on data collected at health services.
CONCLUSIONS: The lack of prevalence data and analysis of determinants is a detriment to the health of the Roma and Sinti populations in Italy. Participatory research and evidence-based interventions are needed to improve health outcomes and living conditions of the Roma and Sinti people

Simultaneous determination of multiple cytokines reveals a pro-inflammatory and pro-angiogenic signature after major cardiothoracic surgery: Potential role of C-reactive protein.
No full textMany studies have shown that C-reactive protein (CRP) is associated with increased cardiovascular risk. Elevated concentrations of CRP are associated with increased risk of coronary events and mortality in patients with coronary artery disease (CAD), in other high-risk individuals, and apparently in healthy people, independently from other cardiovascular risk factors. Although CRP has traditionally been considered to be a nonspecific acute phase reactant, CRP accumulates in the macrophage rich areas of the atherosclerotic plaque and modulates the expression and release of macrophage derived pro-inflammatory cytokines. In patients with stable or unstable angina, plasma concentrations of CRP >3 mg/l are associated with an increased risk of coronary events. On these bases, we have investigated the circulating levels of CRP and of a panel of 27 pro-inflammatory cytokines/chemokines in patients before and after major cardiothoracic (elective coronary bypass) surgery
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
