Rubella is a contagious disease that can be very serious, especially in unvaccinated pregnant women. The best way to be protected is getting vaccinated: MMR vaccine is very effective at protecting people against measles, mumps, and rubella, and preventing the complications caused by these diseases. According to PASSI 2012-2015 (the Italian behavioral risk factor surveillance system) in the territory of ex ASL Roma C only 56% of women between 18 and 49 years were immunized against rubella, thanks to vaccination (34%) or past infection detected by rubeotest (22%); 2% was susceptible and 42% of respondents did not know their immune status against rubella...

The aim of this observational descriptive study was to identify the main international models evaluating the quality of nursing homes for non self-sufficient elderly persons, and to apply them in the Italian health system. Firstly, a bibliographic search of institutional websites and Pubmed-Medline was performed to identify the main international models. Secondly, three variables were chosen to evaluate the level of implementability of the models: (1) frequency of use of quality indicators in the international models; (2) degree of constructability of the models in two Italian nursing homes; (3) perceived relevance of the indicators used by the chosen models, by nursing home workers...

Epithelial-mesenchymal transition (EMT) is recognized as a relevant process during the progression of carcinomas towards metastatic disease. Epithelial cancer cells undergoing an EMT program may acquire mesenchymal features, motility, invasiveness, and resistance to a variety of anticancer therapeutics. Preventing or reverting the EMT process in carcinomas has the potential to minimize tumor dissemination and the emergence of therapeutic resistance. One of the strategies currently under investigation to target tumor cells undergoing EMT is the generation of a sustained immune response directed against an essential molecular driver of the process...

Emerging variant of pseudorabies virus (PRV) have evaded the antiviral immunity of commercially available PRV vaccine and have led to PRV outbreaks in Chinese pig farms. Here, we attenuated a PRV variant strain by serial passages in vitro and evaluate the protective efficacy of the attenuated strain as a vaccine candidate. The virulent PRV variant strain JS-2012 was continuously passaged in Vero cells at 40°C and attenuated rapidly. After 90 passages in Vero cells, the passaged virus lost its ability to cause death in 2-week-old piglets...

REVIEW
Joaquin Bellmunt, Thomas Powles, Nicholas J Vogelzang
The treatment of bladder cancer has evolved over time to encompass not only the traditional modalities of chemotherapy and surgery, but has been particularly impacted by the use of immunotherapy. The first immunotherapy was the live, attenuated bacterial Bacillus Calmette-Guérin vaccine, which has been the standard of care non-muscle-invasive bladder cancer since 1990. Modern immunotherapy has focused on inhibitors of checkpoint proteins, which are molecules that impede immune function, thereby allowing tumor cells to grow and proliferate unregulated...

Identification of antigen for inducing specific class of antibody is prime objective in peptide based vaccine designs, immunodiagnosis, and antibody productions. It's urge to introduce a reliable system with high accuracy and efficiency for prediction. In the present study, a novel multilevel ensemble model is developed for prediction of antibodies IgG and IgA. Epitope length is important in training the model and it is efficient to use variable length of epitopes. In this ensemble approach, seven different machine learning models are combined to predict variable length of epitopes (4 to 50)...

INTRODUCTION: Neighborhood social cohesion has been linked with better health and health behaviors, but its association with patterns of preventive healthcare use remains understudied. The hypothesis was that people with higher perceived neighborhood social cohesion would display increased use of preventive healthcare services. METHODS: Participants (N=7,168) were drawn from the 2006 wave of the Health and Retirement Study-a prospective and nationally representative panel study of American adults aged >50 years-and tracked for one wave (2 years)...

In the Kingdom of Saudi Arabia (KSA), rotavirus universal mass vaccination has been introduced in 2013, however, there is limited information available on the economic benefit and the epidemiological impact of the programme to date. We used a Markov cohort model to evaluate and compare the economic value of rotavirus vaccination with no vaccination in a birth cohort of 562,428 infants. This lifetime analysis considered the societal perspective. Model input was obtained through consensus of local experts after two rounds of evaluation of the proposed estimates...

Vaccination in immunocompetent adult mainly concerns booster vaccination against diphtheria, tetanus, polio and pertussis. Some chronic diseases may also require the achievement of pneumococcal and influenza vaccines. In addition, from the age of 65, annual influenza vaccination as well as one dose of a live attenuated shingles vaccine between 64 and 75 years are recommended. Immunocompromised adults, due to the increased risk of serious infections responsible of significant morbidity and mortality, are particularly concerned by vaccination...

The NIH test is currently used to assess the potency of rabies vaccine, a key criterion for vaccine release. This test is based on mice immunization followed by intracerebral viral challenge. As part of global efforts to reduce animal experimentation and in the framework of the development of Sanofi Pasteur next generation, highly-purified vaccine, produced without any material of human or animal origin, we developed an ELISA as an alternative to the NIH test. This ELISA is based on monoclonal antibodies recognizing specifically the native form of the viral G-protein, the major antigen that induces neutralizing antibody response to rabies virus...

Nursing students are at high risk of exposure to vaccine-preventable diseases such as seasonal influenza. However, due to the limited number of studies conducted in this area, the prevalence and factors affecting annual seasonal influenza vaccination (ASIV) uptake remain unclear. This was a large-scale cross-sectional survey study conducted among 902 nursing students in different years of study. The questionnaire was developed based on the Health Belief Model (HBM), and logistic regression was used to determine the predictors of ASIV uptake...

To address the need for vaccine platforms that induce robust cell-mediated immunity, we investigated the potential of utilizing self-assembling biologic nanolipoprotein particles (NLPs) as an antigen and adjuvant delivery system to induce antigen-specific murine T cell responses. We utilized OT-I and OT-II TCR-transgenic mice to investigate the effects of NLP-mediated delivery of the model antigen ovalbumin (OVA) on T cell activation. Delivery of OVA with the TLR4 agonist monophosphoryl lipid A (MPLA) in the context of NLPs significantly enhanced the activation of both CD4(+) and CD8(+) T cells in vitro compared to co-administration of free OVA and MPLA...

Although culture is considered the gold standard for poliovirus detection from stool samples, real-time PCR has emerged as a faster and more sensitive alternative. Detection of poliovirus from the stool of recently vaccinated children by culture, single and multiplex real-time PCR was compared. Of the 80 samples tested, 55 (68.75%) were positive by culture compared to 61 (76.25%) and 60 (75%) samples by the single and one step multiplex real-time PCR assays respectively. Real-time PCR (singleplex and multiplex) is more sensitive than culture for poliovirus detection in stool, although the difference was not statistically significant...

The prevalence of serum antibodies against C. difficile (CD) toxins A and B in healthy populations have prompted interest in evaluating the therapeutic activity of intravenous immunoglobulin (IVIg) in individuals experiencing severe or recurrent C. difficile infection (CDI). Despite some promising case reports, a definitive clinical role for IVIg in CDI remains unclear. Contradictory results may be attributed to a lack of consensus regarding optimal dose, timing of administration and patient selection as well as variability in specific antibody content between commercial preparations...

PURPOSE: Besides cervical cancer, HPV infection is linked to a multitude of diseases in both males and females, suggesting that vaccination programmes should be re-evaluated, with a judicious assessment made of the disease burden stratified by sex, age, and genotype. Projections of burden into the near future are also needed to provide a benchmark for evaluating the impact of vaccination programmes, and to assess the need for scaling-up preventive measures. METHODS: Using the disability-adjusted life-years (DALY) measure, we estimated the total HPV-associated disease burden in the Netherlands...

Mayaro virus (MAYV) is an arthropod-borne virus and a member of the family Togaviridae, genus Alphavirus. Its infection leads to an acute illness accompanied by long-lasting arthralgia. To date, there are no antiviral drugs or vaccines against infection with MAYV and resources for the prevention or treatment of other alphaviruses are very limited. MAYV has served as a model to study the antiviral potential of several substances on alphavirus replication. In this work we evaluated the antiviral effect of seven new derivatives of thieno[2,3-b]pyridine against MAYV replication in a mammalian cell line...

Natural focal diseases are caused by biological agents associated with specific landscapes. The natural focus of such diseases is defined as any natural ecosystem containing the pathogen's population as an essential component. In such context, the agent circulates independently on human presence, and humans may become accidentally infected through contact with vectors or reservoirs. Some viruses (i.e., tick-borne encephalitis and Congo-Crimean hemorrhagic fever virus) are paradigmatic examples of natural focal diseases...

In the search of strategies of presentation of heterologous antigens to elicit humoral or cellular immune responses that modulate and properly potentiate each type of response, researchers have been studying baculovirus (BV) as vaccine vectors with promising results. For some years, several research groups explored different antigen presentation approaches using the BV AcNPV by expressing polypeptides on the surface of budded virions or by de novo synthesis of heterologous antigens by transduction of mammalian cells...
