Economic implications in inflammatory bowel disease: results from a retrospective analysis in an Italian Centre

BACKGROUND: Inflammatory bowel disease (IBD) represents a group of chronic conditions characterized by elevated costs. Over the last years, also a considerable healthcare burden associated with IBD has emerged, due to an increasing use of biological drugs and hospitalization costs. Despite the creation of local or regional databases, data regarding healthcare expenditure are lacking in Italy.AIM: To evaluate the treatment cost (biological drugs and hospitalizations) for patients with ulcerative colitis (UC) or Crohn’s disease (CD) treated with biological drugs.METHODS: Disease severity was evaluated by clinical scores (partial Mayo score and Harvey Bradshaw Index). We analyzed retrospectively patients treated with biologics referred to our IBD Unit between May 2015-April 2016 who underwent at least six months of follow-up (last visit October 2016). We calculated a mean cost per month of treatment for each patient. We also investigated the presence of any correlation between the monthly cost of treatment and demographic or clinical variables.RESULTS: We enrolled 142 patients (52 UC, mean age 44.3 years, male 40.4%; 90 CD, mean age 38.8 years, male 56.7%). About half of CD patients (48.9%) underwent previous intestinal surgery. The disease severity was higher in UC group vs CD group. In UC group infliximab was the most prescribed biologic (51.9%), followed by golimumab (26.9%) and adalimumab (21.2%). While CD patients were treated with adalimumab in 54.4% and infliximab in 45.6%. The mean monthly cost of treatment was € 1,235.41 ± 358.38 for UC and € 1,148.92 ± 337.36 for CD (p = 0.16). In both groups expenditure due to biologics amounts for more than 80%. We found a correlation between costs and disease activity (UC: p < 0.01; CD: p < 0.01).CONCLUSION: The main cost is due to biological drugs, but patients enrolled were the most severe in comparison to the whole IBD population under conventional therapy. As no cost differences were found between biologic drugs and the way of administration (intravenous or subcutaneous), the therapeutic choice should be driven by clinical reasons and not only economic ones

Tailoring crystallinity for hemocompatible and durable PEEK cardiovascular implants

Polymers have the potential to replace metallic or bioprosthetic heart valve components due to superior durability and inertness while allowing for native tissue-like flexibility. Despite these appealing properties, certain polymers such as polyetheretherketone (PEEK) have issues with hemocompatibility, which have previously been addressed through assorted complex processes. In this paper, we explore the enhancement of PEEK hemocompatibility with polymer crystallinity. Amorphous, semi-crystalline and crystalline PEEK are investigated in addition to a highly crystalline carbon fiber (CF)/PEEK composite material (CFPEEK). The functional group density of the PEEK samples is determined, showing that higher crystallinity results in increased amount of surface carbonyl functional groups. The increase of crystallinity (and negatively charged groups) appears to cause significant reductions in platelet adhesion (33 vs. 1.5 % surface coverage), hemolysis (1.55 vs. 0.75 %∙cm$^{-2}$), and thrombin generation rate (4840 vs. 1585 mU/mL/min/cm$^{2}$). In combination with the hemocompatibility study, mechanical characterization demonstrates that tailoring crystallinity is a simple and effective method to control both hemocompatibility and mechanical performance of PEEK. Furthermore, the results display that CFPEEK composite performed very well in all categories due to its enhanced crystallinity and complete carbon encapsulation, allowing the unique properties of CFPEEK to empower new concepts in cardiovascular device design

Eligibility criteria for pediatric patients who may benefit from anti SARS-CoV-2 monoclonal antibody therapy administration: an Italian inter-society consensus statement

The fast diffusion of the SARS-CoV-2 pandemic have called for an equally rapid evolution of the therapeutic options.The Human recombinant monoclonal antibodies (mAbs) have recently been approved by the Food and Drug Administration (FDA) and by the Italian Medicines Agency (AIFA) in subjects aged ≥12 with SARS-CoV-2 infection and specific risk factors.Currently the indications are specific for the use of two different mAbs combination: Bamlanivimab+Etesevimab (produced by Eli Lilly) and Casirivimab+Imdevimab (produced by Regeneron).These drugs have shown favorable effects in adult patients in the initial phase of infection, whereas to date few data are available on their use in children.AIFA criteria derived from the existing literature which reports an increased risk of severe COVID-19 in children with comorbidities. However, the studies analyzing the determinants for progression to severe disease are mainly monocentric, with limited numbers and reporting mostly generic risk categories.Thus, the Italian Society of Pediatrics invited its affiliated Scientific Societies to produce a Consensus document based on the revision of the criteria proposed by AIFA in light of the most recent literature and experts' agreement.This Consensus tries to detail which patients actually have the risk to develop severe disease, analyzing the most common comorbidities in children, in order to detail the indications for mAbs administration and to guide the clinicians in identifying eligible patients

Ventricular septal defect in a child with Alport syndrome: a case report

<p>Abstract</p> <p>Background</p> <p>Alport syndrome (AS) is a rare inherited disorder characterized by an inflammation of the kidneys and damage to the glomerular capillaries, ultimately leading to renal failure at an early age. To date, rare reports of cardiac involvement in AS have been described, due in the majority of cases to the higher risk of heart conduction abnormalities in these patients, at times requiring implantation of a transcutaneous pacemaker. An increased risk of hypertension is likewise commonly featured.</p> <p>Case presentation</p> <p>We report the case of a 17-year-old female affected by a very severe early form of AS. A previously unreported association of the syndrome with congenital heart disease (CHD), (in this case membranous ventricular septal defect), is also reported. A possible pathophysiological mechanism underlying the concomitant manifestation of these two disorders is suggested. Complications implicated in surgical treatment of CHD are described. Clinical and therapeutic management of AS with cardiovascular involvement are discussed, and a short literature review performed.</p> <p>Conclusions</p> <p>This first report of a cardiovascular association highlights the possible involvement of collagen mutations in the two pathologies. Even when drug-resistance appears to be responsible for the failure to control secondary hypertension in AS, clonidine may represent a safe, effective option in the normalization of high blood pressure.</p

Compulsory language educational policies and identity formation

Education can be at the root of the process of identity formation. Using survey data from Catalonia and the Basque Country, where in 1983 the education system became bilingual, we study how parental choices and schooling interact with each other and contribute to the development of individual identity. The difference between the reforms implemented in the two Spanish regions is that whereas in Catalonia the reform was compulsory, in the Basque Country parents could choose the language used to educate their children. Results show a significant effect of the compulsory language policy implemented in Catalonia on identity, whereas the non-compulsory language policy implemented in the Basque Country does not have any effect

Designing Polymeric Cardiovascular Biomaterials for Hemocompatibility and Mechanical Performance

One of the greatest challenges facing polymeric cardiovascular devices is the issue of hemocompatibility. Devices such as polymeric heart valves potentially offer improved mechanical properties and quality of life compared to their animal tissue counterparts. However, they are still strongly limited by problematic interactions with blood. The reduction of platelet adhesion, thrombogenicity, and calcification have been addressed in a variety of surface and bulk modification methods, generally by increasing the hydrophilic character of polymers. However, most hydrophilization processes – oxygen plasma in particular – tend to offer limited longevity. The crystallinity of polymers has previously been observed to influence the extent of platelet adhesion, though the underlying mechanisms for this phenomenon are not clear. In this research, we report on the effect of crystallinity on hemolysis, thrombogenicity, and platelet adhesion in PEEK surfaces. By tailoring the bulk crystallinity, we demonstrate changes in the surface chemical composition and propose a potential strategy to achieve longer term surface modification for improved hemocompatibility. Additionally, we explore the influence of crystallinity on the mechanical properties of thin PEEK films, establishing the multi-dimensional impact of polymer crystallinity. The results shown here may have implications for the design of polymeric cardiovascular devices and considerations that should be taken during material selection

Seasonal variability of thermophilic campylobacter spp. In raw milk sold by automatic vending machines in Lombardy

In temperate climates, a seasonal trend was observed in the incidence of human campylobacteriosis cases, with peaks reported in spring and autumn in some countries, or in summer in others; a similar trend was observed in Campylobacter spp. dairy cattle fecal shedding, suggesting that cattle may play a role in the seasonal peak of human infection. The objectives of this study were to assess if a seasonal trend in thermophilic Campylobacter spp. contamination of raw milk exists and to evaluate a possible relation between this and the increase of human campylobacteriosis incidence in summer months. The results showed a mean prevalence of 1.6% of milk samples positive for thermophilic Campylobacter spp. with a wide range in different months during the three years considered of 0.0-3.1%. The statistical analysis showed a significant difference (P<0.01) of the prevalence of positive samples for thermophilic Campylobacter spp. between warmer and cooler months (2.3% vs 0.6%). The evidence of a seasonal trend in thermophilic Campylobacter spp. contamination of raw milk sold for direct consumption, with an increase of the prevalence in warmer months, may represent one of the possible links between seasonal trend in cattle fecal shedding and seasonal trend in human campylobacteriosis
