COVID-19 Vaccination in Pregnancy, Paediatrics, Immunocompromised Patients, and Persons with History of Allergy or Prior SARS-CoV-2 Infection: Overvi…
2021
To date, four vaccines have been authorised for emergency use and under conditional approval by the European Medicines Agency to prevent COVID-19: Comirnaty, COVID-19 Vaccine Janssen, Spikevax (previously COVID-19 Vaccine Moderna) and Vaxzevria (previously COVID-19 Vaccine AstraZeneca). Although the benefit–risk profile of these vaccines was proven to be largely favourable in the general population, evidence in special cohorts initially excluded from the pivotal trials, such as pregnant and breastfeeding women, children/adolescents, immunocompromised people and persons with a history of allergy or previous SARS-CoV-2 infection, is still limited. In this narrative review, we critically overv…
Choosing wisely: Practical considerations on treatment efficacy and safety of asthma in the elderly
2015
The prevalence of asthma in the most advanced ages is similar to that of younger ages. However, the concept that older individuals may suffer from allergic asthma has been largely denied in the past, and a common belief attributes to asthma the definition of "rare" disease. Indeed, asthma in the elderly is often underdiagnosed or diagnosed as COPD, thus leading to undertreatment of improper treatment. This is also due to the heterogeneity of clinical and functional presentations of geriatric asthma, including the partial loss of reversibility and the lower occurrence of the allergic component in this age range. The older asthmatic patients are also characterized the coexistence of comorbid …
Martyrdom in Contemporary Animalist Discourses
2019
Is it possible to use the notion of martyrdom in order to explain the communicative strategies and the semiotic mechanisms of the animalist movement? Is the animal a sort of contemporary martyr? This study aims to apply the notion of martyrdom outside the traditional boundaries of religion and politics, testing it in another relevant socio–cultural phenomenon: the contemporary animalist discourse. This paper analyses texts from animalist advertising, essays and novels promoting animal rights and vegetarianism. The main features of the traditional notion of martyrdom are compared to the semiotic structures of the animalist discourse. The questions of the efficacy of images and that of the ex…
Anti-fouling additives for the consolidation of archaeological mortars in underwater environment: Efficacy tests performed on the apsidal fishpond of…
2020
This paper deals with the formulation of innovative mortars for the consolidation of archeological structures in underwater environment. The research was conducted within the frame of the MaTaCoS project (Advanced materials and technologies applied to the conservation of underwater cultural heritage) funded by MISE (Italian Ministry of Economic Development). The project concerns the design of advanced tools and methods for the protection of Underwater Cultural Heritage, through specific cleaning and consolidating procedures to be applied directly in situ. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. I…
Parents’ Willingness and Perception of Children’s Autonomy as Predictors of Greater Independent Mobility to School
2019
The present study aimed to examine the factors associated with different forms of independent mobility (IM) to school (IM one way and IM both ways) according to their parents&rsquo
Persistence of protection through 33 months of age provided by immunization in infancy with two three-component acellular pertussis vaccines
1998
Abstract A large, randomized, placebo-controlled clinical trial in Italy on two three-component pertussis vaccines, given as DTaP in infancy, one manufactured by SmithKline and Beecham (SB) and one by Chiron Biocine (CB), found each vaccine to be 84% efficacious through the average age of 24 months. The cohort of children envolled in the trial was followed with unmodified case ascertainment procedures for nine additional calendar months, during which partial unblinding occurred, for the unvaccinated randomized group. For the DTaP groups, the specific vaccine assignment remained double-blinded throughout the entire additional observation period. Pertussis was defined as paroxysmal cough last…
Efficacy of Acellular Pertussis Vaccine in Early Childhood After Household Exposure
1996
Objective. —To evaluate the efficacy of a three-dose primary vaccination with a diphtheria-tetanus tricomponent acellular pertussis vaccine against "typical" pertussis, defined as a spasmodic cough of 21 days or longer with confirmation of Bordetella pertussis infection by culture or serology. Design. —Passive monitoring for suspected first household (index) cases of typical pertussis in six areas in Germany comprising 22 505 children vaccinated with study vaccine at 3, 4, and 5 months of age. Blinded, prospective follow-up of household contacts of index cases for incidence and progression of pertussis. Setting. —Six areas in Germany with a high incidence of pertussis. Subjects. —Four hundr…
Coverage, efficacy or dosing interval: which factor predominantly influences the impact of routine childhood vaccination for the prevention of varice…
2016
Background Varicella is a highly infectious disease with a significant public health and economic burden, which can be prevented with childhood routine varicella vaccination. Vaccination strategies differ by country. Some factors are known to play an important role (number of doses, coverage, dosing interval, efficacy and catch-up programmes), however, their relative impact on the reduction of varicella in the population remains unclear. This paper aims to help policy makers prioritise the critical factors to achieve the most successful vaccination programme with the available budget. Methods Scenarios assessed the impact of different vaccination strategies on reduction of varicella disease…
Timing of activation of CD4+ memory cells as a possible marker to establish the efficacy of vaccines against contagious agalactia in sheep
2013
Mycoplasma agalactiae is a major pathogen of sheep and goats in many areas of the world and particularly in Mediterranean countries. It causes contagious agalactia, an infectious disease primarily affecting mammary glands. Many vaccines against the pathogen are currently under development. The aim of the study was to investigate the involvement of T cell-mediated immunity during vaccination and challenge experiments against Mycoplasma agalactiae. A comparison of the antigen-specific expansion of interferon gamma positive T cell memory and naïve subsets was performed between vaccinated and non-vaccinated sheep to identify cellular subsets whose activation was different between protected and …
A randomized phase II study of estramustine phosphate versus estramustine phosphate plus etoposide in hormone refractory prostate cancer (HRPC)
2008
20632 Background: Docetaxel-based regimens represent the treatment of choice of HRPC. However, in some patients toxicity may be a concern and the quality of life may be compromised. The aim of this phase II randomized study is to investigate the efficacy and safety of low-dose chemotherapy regimen adopting a combination of EMP and VP16 in patients affected by HRPC. Methods: 54 HRPC patients were randomized between: arm A, daily oral standard dose EMP (10mg/kg) and arm B, low-dose EMP (3mg/kg) plus VP16 (25mg/mq) for 2 weeks followed by 2-weeks’rest. Systemic toxicity and hematologic exams were monitored every 2 weeks. Performance status, pain and analgesic use were evaluated according to WH…
