Global, regional, and national incidence and mortality for HIV, tuberculosis, and malaria during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis, and malaria through the formulation of Millennium Development Goal (MDG) 6. The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation for between 1990 and 2013, and an opportunity to assess whether accelerated progress has occured since the Millennium Declaration.

Methods: To estimate incidence and mortality for HIV, we used the UNAIDS Spectrum model appropriately modified based on a systematic review of available studies of mortality with and without antiretroviral therapy (ART).

Genetic polymorphisms and sepsis in premature neonates.

Identifying single nucleotide polymorphisms (SNPs) in the genes involved in sepsis may help to clarify the pathophysiology of neonatal sepsis. The aim of this study was to evaluate the relationships between sepsis in pre-term neonates and genes potentially involved in the response to invasion by infectious agents. The study involved 101 pre-term neonates born between June 2008 and May 2012 with a diagnosis of microbiologically confirmed sepsis, 98 pre-term neonates with clinical sepsis and 100 randomly selected, otherwise healthy pre-term neonates born during the study period.

Prevalence of epilepsy--an unknown quantity.

The incidence, prevalence, and mortality of epilepsy vary across countries with different economies. Differences can be explained by methodological problems, premature mortality, seizure remission, socioeconomic factors, and stigma. Diagnostic misclassification-one possible explanation-may result from inclusion of patients with acute symptomatic or isolated unprovoked seizures.

Involvement of users and relatives in mental health service evaluation.

Although Italian mental health (MH) services are community based, user and relative participation in service evaluation lagged behind until lately. We here review three recent studies involving stakeholder participation in service evaluation: two were quantitative studies, one on 204 users in an MH service in Pistoia (Central Italy) and the other on 2259 relatives, conducted with the National Union of Associations for Mental Health. The third (supported by The Centro per il Controllo delle Malattie, the ministerial Center for Disease Control) was a qualitative study in seven MH services, involving users, relatives, and professionals together, which collected interviews from 136 users, 119 relatives, and 79 professionals.

Regional tenders on biosimilars in Italy: an empirical analysis of awarded prices.

Objective: The goal of the present study is to assess the awarded prices and thus the real level of competition the regional tenders referring to biosimilars in Italy achieved.

Methods: We conducted a web-based analysis to collect detailed information on regional biosimilar tenders, up to December 2012. We identified 191 lots referring to the three off-patent biologicals (somatropin, epoetin and filgrastim) mentioned in the 24 tenders that took place during the study period (2008-2012).

Hydrogel-based nanocomposites and mesenchymal stem cells: a promising synergistic strategy for neurodegenerative disorders therapy.

Hydrogel-based materials are widely employed in the biomedical field. With regard to central nervous system (CNS) neurodegenerative disorders, the design of injectable nanocomposite hydrogels for in situ drug or cell release represents an interesting and minimally invasive solution that might play a key role in the development of successful treatments. In particular, biocompatible and biodegradable hydrogels can be designed as specific injectable tools and loaded with nanoparticles (NPs), to improve and to tailor their viscoelastic properties upon injection and release profile.

Diagnostic accuracy of five serologic tests for Strongyloides stercoralis infection.

Background: The diagnosis of Strongyloides stercoralis (S. stercoralis) infection is hampered by the suboptimal sensitivity of fecal-based tests. Serological methods are believed to be more sensitive, although assessing their accuracy is difficult because of the lack of sensitivity of a fecal-based reference ("gold") standard.

Pharmacological and clinical differences among transmucosal fentanyl formulations for the treatment of breakthrough cancer pain: a review article.

Breakthrough pain (BTP) is highly prevalent (59.2%) in chronic cancer patients and normally needs rescue treatments' with opioids when pain flares up. Transmucosal oral/nasal fentanyl formulations are commonly used in clinical practice.

Sensitivity and predictive value of anti-GM1/galactocerebroside IgM antibodies in multifocal motor neuropathy.

Background: Increased titres of serum IgM antibodies to GM1 ganglioside are often associated with multifocal motor neuropathy (MMN). Testing for IgM antibodies to other antigens including GM2, the mixture of GM1 and galactocerebroside (GM1/GalC) and the disulfated heparin disaccharide NS6S were reported to increase the sensitivity of antibody testing in MMN even if it is unclear whether the specificity and positive (PPV) or negative predictive value (NPV) for MMN were also affected.

Methods: We measured IgM antibodies to GM1, GM2, galactocerebroside, GM1/GalC and NS6S in 40 consecutive patients with MMN and 142 controls with other neuropathies or related diseases and compared their sensitivity, specificity and PPV for MMN.

Validation of a patient-specific hemodynamic computational model for surgical planning of vascular access in hemodialysis patients.

Vascular access dysfunction is one of the main causes of morbidity and hospitalization in hemodialysis patients. This major clinical problem points out the need for prediction of hemodynamic changes induced by vascular access surgery. Here we reviewed the potential of a patient-specific computational vascular network model that includes vessel wall remodeling to predict blood flow change within 6 weeks after surgery for different arteriovenous fistula configurations.
