Second European Multi-Disciplinary Conference of National Strategies for Chlamydia Trachomatis and Human Papillomavirus (NSCP Conference) in Berlin, …
2013
There is a need for updated guidance on detection, management and surveillance of sexually transmitted infections (STIs). Chlamydia, gonorrhoea and syphilis reporting needs to be mandatory in more European countries to aid collection of data. More widespread Chlamydia screening is needed in many countries as this is the only way to reduce complications. The role of Human Papillomavirus (HPV) screening in a situation where the prevalence of HPV infection has dropped significantly was also discussed in the context of the high cost of screening, the need for a relatively complex infrastructure, particularly in developing countries, and falling vaccination costs. An integrated HPV vaccination …
Novel Approaches for Glioblastoma Treatment: Focus on Tumor Heterogeneity, Treatment Resistance, and Computational Tools
2019
BACKGROUND: Glioblastoma (GBM) is a highly aggressive primary brain tumor. Currently, the suggested line of action is the surgical resection followed by radiotherapy and treatment with the adjuvant temozolomide (TMZ), a DNA alkylating agent. However, the ability of tumor cells to deeply infiltrate the surrounding tissue makes complete resection quite impossible, and in consequence, the probability of tumor recurrence is high, and the prognosis is not positive. GBM is highly heterogeneous and adapts to treatment in most individuals. Nevertheless, these mechanisms of adaption are unknown. RECENT FINDINGS: In this review, we will discuss the recent discoveries in molecular and cellular heterog…
Efficacy of a bivalent vaccine against eel diseases caused by Vibrio vulnificus after its administration by four different routes
2003
Vulnivaccine, a vaccine against vibriosis caused by Vibrio vulnificus serovar E (formerly biotype 2), confers acceptable levels of protection to eels after its administration by prolonged immersion in three doses. Recently, a new pathogenic serovar, named serovar A, has been isolated from vaccinated eels in a Spanish freshwater eel farm. The main objective of this work was to design a bivalent vaccine, and to study its effectiveness against the two pathogenic serovars. With this aim, eels weighing around 20 g were immunised with the bivalent vaccine by oral and anal intubation, intraperitoneal injection (i.p.) and prolonged immersion. The overall results indicated that: (i) the new vaccine …
Fasciola spp: Mapping of the MF6 epitope and antigenic analysis of the MF6p/HDM family of heme-binding proteins
2017
MF6p/FhHDM-1 is a small cationic heme-binding protein which is recognized by the monoclonal antibody (mAb) MF6, and abundantly present in parenchymal cells and secreted antigens of Fasciola hepatica. Orthologs of this protein (MF6p/HDMs) also exist in other causal agents of important foodborne trematodiasis, such as Clonorchis sinensis, Opisthorchis viverrini and Paragonimus westermani. Considering that MF6p/FhHDM-1 is relevant for heme homeostasis in Fasciola and was reported to have immunomodulatory properties, this protein is expected to be a useful target for vaccination. Thus, in this study we mapped the epitope recognized by mAb MF6 and evaluated its antigenicity in sheep. The sequenc…
Dinamiche della colonizzazione da pneumococco in Sicilia tra il 2009 ed il 2017: implicazioni nella vaccinazione anti-pneumococcica in soggetti di tu…
2019
Introduzione Streptococcus pneumoniae è uno dei maggiori responsabili di meningiti, sepsi e polmoniti a livello globale. La colonizzazione asintomatica da pneumococco (carriage) rappresenta il reservoir di sierotipi batterici ed è considerata un pre-requisito per lo sviluppo della malattia. In questo lavoro viene descritto l’andamento del carriage da pneumococco e la distribuzione dei sierotipi circolanti in Sicilia, una delle regioni italiane a proporre nei nuovi nati, già dal 2004, la vaccinazione universale con il vaccino anti pneumococcico coniugato e dal 2013 anche nei soggetti a rischio di qualsiasi età e negli adulti over-65. Materiali e metodi Soggetti di tutte le età, giunti all’os…
L’istruttoria ai fini della valutazione della non manifesta infondatezza delle questioni di legittimità costituzionale sull’obbligo vaccinale: profil…
2022
Il contributo esamina alcuni effetti che l’ordinanza n. 38 del 2022 del Consiglio di giustizia amministrativa per la Regione Siciliana nel disporre accertamenti istruttori preliminari alla valutazione della non manifesta infondatezza delle questioni prospettate dagli appellanti – potrebbe produrre nell’eventuale giudizio di costituzionalità del c.d. obbligo vaccinale selettivo previsto dall’art. 4, c. 1 del D.L. n. 44 del 2021, convertito con modifiche dalla legge n. 76 del 2021
Peptide Processing Is Critical for T-Cell Memory Inflation and May Be Optimized to Improve Immune Protection by CMV-Based Vaccine Vectors.
2016
Cytomegalovirus (CMV) elicits long-term T-cell immunity of unparalleled strength, which has allowed the development of highly protective CMV-based vaccine vectors. Counterintuitively, experimental vaccines encoding a single MHC-I restricted epitope offered better immune protection than those expressing entire proteins, including the same epitope. To clarify this conundrum, we generated recombinant murine CMVs (MCMVs) encoding well-characterized MHC-I epitopes at different positions within viral genes and observed strong immune responses and protection against viruses and tumor growth when the epitopes were expressed at the protein C-terminus. We used the M45-encoded conventional epitope HGI…
Immunogenicity and reactogenicity of a Haemophilus influenzae type b tetanus conjugate vaccine when administered separately or mixed with concomitant…
1998
With an increasing number of new vaccines available for routine childhood immunization, combination vaccines are needed in order to maintain or achieve a high compliance with recommended immunization programmes. In a prospective, randomized, comparative, multi-centre study, 822 healthy infants were enrolled to receive three doses of either a candidate or a commercially available Haemophilus influenzae type b (Hib) vaccine concomitantly with diphtheria-, tetanus- acellular pertussis (DTaP) vaccine. Study subjects were randomly allocated to one of the following groups: (1) separate, or (2) mixed injection of DTaP and candidate Hib vaccine, or (3) separate injection of DTaP and commercial Hib …
Spanish Society of Hematology and Hemotherapy expert consensus opinion for SARS-CoV-2 vaccination in onco-hematological patients.
2021
Abstract In the midst of the COVID-19 pandemic, different vaccines in front of SARS-CoV-2 have been approved and administered in different vulnerable populations. As patients with cancer were excluded from pivotal trials of vaccination, little is known on their immunogenic response to these vaccines, particularly in patients with severely impaired immune system. In response to that uncertainty, the Spanish Society of Hematology and Hemotherapy launched an initiative aimed to provide recommendations for vaccination of the main hematological conditions. This document is based on the available information on COVID-19 outcomes, prior knowledge on vaccination in hematological patients, recent pu…
Prevalence of unwillingness and uncertainty to vaccinate against COVID-19 in older people: A systematic review and meta-analysis.
2021
The coronavirus disease 2019 (COVID-19) has been shown to have more severe health outcomes in older people specifically in relation to mortality and disability. Vaccination seems to be efficacious and safe for preventing the negative consequences of COVID-19, but vaccine hesitancy seems to be high in older adults. We therefore aimed to investigate the prevalence of unwillingness and the uncertainty to vaccinate against COVID-19 in older people and the factors that can be associated with the unwillingness to vaccinate. For this work, we searched several databases until 18th June 2021 for studies reporting the prevalence of unwillingness and the uncertainty to vaccinate against COVID-19 in pe…
