Global impact of ten-valent and 13-valent pneumococcal conjugate vaccines on invasive pneumococcal disease in all ages (the PSERENADE project): a global surveillance analysis.

Background: Pneumococcal conjugate vaccines (PCVs) that are ten-valent (PCV10) and 13-valent (PCV13) became available in 2010. We evaluated their global impact on invasive pneumococcal disease (IPD) incidence in all ages.

Methods: Serotype-specific IPD cases and population denominators were obtained directly from surveillance sites using PCV10 or PCV13 in their national immunisation programmes and with a primary series uptake of at least 50%.

Effectiveness of 10 and 13-valent pneumococcal conjugate vaccines against invasive pneumococcal disease in European children: SpIDnet observational multicentre study.

Background: Pneumococcal conjugate vaccines covering 10 (PCV10) and 13 (PCV13) serotypes have been introduced in the infant immunization schedule of most European countries in 2010-11. To provide additional real-life data, we measured the effectiveness of PCV10 and PCV13 against invasive pneumococcal disease (IPD) in children of 12 European sites (SpIDnet).

Methods: We compared the vaccination status of PCV10 and PCV13 serotype IPD (cases) to that of nonPCV13 serotype IPD (controls) reported in 2012-2018.

Serotype Replacement after Introduction of 10-Valent and 13-Valent Pneumococcal Conjugate Vaccines in 10 Countries, Europe.

We evaluated invasive pneumococcal disease (IPD) during 8 years of infant pneumococcal conjugate vaccine (PCV) programs using 10-valent (PCV10) and 13-valent (PCV13) vaccines in 10 countries in Europe. IPD incidence declined during 2011-2014 but increased during 2015-2018 in all age groups. From the 7-valent PCV period to 2018, IPD incidence declined by 42% in children <5 years of age, 32% in persons 5-64 years of age, and 7% in persons >65 years of age; non-PCV13 serotype incidence increased by 111%, 63%, and 84%, respectively, for these groups.

Human papillomavirus vaccination in the European Union/European Economic Area and globally: a moral dilemma.

While many European Union/European Economic Area (EU/EEA) countries recently expanded human papillomavirus (HPV) vaccination to boys, HPV vaccine supply is currently limited for girls in low- and middle-income countries (LMIC) that are severely affected by HPV.Globally, about 50% of countries have introduced HPV vaccination. Some LMIC with high burden of cervical cancer have not yet introduced HPV vaccination, or are reaching suboptimal vaccination coverage.

Rapidly increasing cumulative incidence of coronavirus disease (COVID-19) in the European Union/European Economic Area and the United Kingdom, 1 January to 15 March 2020.

The cumulative incidence of coronavirus disease (COVID-19) cases is showing similar trends in European Union/European Economic Area countries and the United Kingdom confirming that, while at a different stage depending on the country, the COVID-19 pandemic is progressing rapidly in all countries. Based on the experience from Italy, countries, hospitals and intensive care units should increase their preparedness for a surge of patients with COVID-19 who will require healthcare, and in particular intensive care.

Potential scenarios for the progression of a COVID-19 epidemic in the European Union and the European Economic Area, March 2020.

Two months after the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the possibility of established and widespread community transmission in the European Union and European Economic Area (EU/EEA) is becoming more likely. We provide scenarios for use in preparedness for a possible widespread epidemic. The EU/EEA is moving towards the 'limited sustained transmission' phase.

Impact of infectious diseases on population health using incidence-based disability-adjusted life years (DALYs): results from the Burden of Communicable Diseases in Europe study, European Union and European Economic Area countries, 2009 to 2013.

Background and aimsThe Burden of Communicable Diseases in Europe (BCoDE) study aimed to calculate disability-adjusted life years (DALYs) for 31 selected diseases in the European Union (EU) and European Economic Area (EEA). DALYs were estimated using an incidence-based and pathogen-based approach. Incidence was estimated through assessment of data availability and quality, and a correction was applied for under-estimation.

Disability weights for infectious diseases in four European countries: comparison between countries and across respondent characteristics.

Background: In 2015, new disability weights (DWs) for infectious diseases were constructed based on data from four European countries. In this paper, we evaluated if country, age, sex, disease experience status, income and educational levels have an impact on these DWs.

Methods: We analyzed paired comparison responses of the European DW study by participants' characteristics with separate probit regression models.

Estimating the annual burden of tick-borne encephalitis to inform vaccination policy, Slovenia, 2009 to 2013.

With an annual incidence between 8 and 15 per 100,000 population in the period from 2009 to 2013, Slovenia has one of the highest notified incidences of tick-borne encephalitis (TBE) in Europe. TBE vaccination coverage remains at about 7.3%.

A Software Tool for Estimation of Burden of Infectious Diseases in Europe Using Incidence-Based Disability Adjusted Life Years.

The burden of disease framework facilitates the assessment of the health impact of diseases through the use of summary measures of population health such as Disability-Adjusted Life Years (DALYs). However, calculating, interpreting and communicating the results of studies using this methodology poses a challenge. The aim of the Burden of Communicable Disease in Europe (BCoDE) project is to summarize the impact of communicable disease in the European Union and European Economic Area Member States (EU/EEA MS).

Breaking the matching in nested case-control data offered several advantages for risk estimation.

Objective: To demonstrate the advantage of using weighted Cox regression to analyze nested case-control data in overcoming limitations encountered with traditional conditional logistic regression.

Study Design And Setting: We analyzed data from 1,051 women who were sampled in a case-control study of lung cancer nested within a cohort of breast cancer patients. We investigated how lung cancer risk is associated with radiation therapy and modified by smoking, with both conditional logistic regression and weighted Cox regression models.

Risk of hospitalisation and death due to bone fractures after breast cancer: a registry-based cohort study.

Background: Bone fractures may have an impact on prognosis of breast cancer. The long-term risks of bone fracture in breast cancer patients have not been thoroughly studied.

Methods: Poisson regression was used to investigate the incidence of hospitalisation due to bone fracture comparing women with and without breast cancer based on Swedish National registers.

Infection-related hospitalizations in breast cancer patients: Risk and impact on prognosis.

Objectives: Infections are a common cause of hospitalization in breast cancer patients. We studied the risk, clinical characteristics and outcomes of infection-related hospitalizations in this patient population.

Methods: A Swedish registry-based study including 8338 breast cancer patients diagnosed between 2001 and 2008, followed prospectively for infection-related hospitalizations until 2010.

Review of disability weight studies: comparison of methodological choices and values.

Introduction: The disability-adjusted life year (DALY) is widely used to assess the burden of different health problems and risk factors. The disability weight, a value anchored between 0 (perfect health) and 1 (equivalent to death), is necessary to estimate the disability component (years lived with disability, YLDs) of the DALY. After publication of the ground-breaking Global Burden of Disease (GBD) 1996, alternative sets of disability weights have been developed over the past 16 years, each using different approaches with regards to the panel, health state description, and valuation methods.

Effects of an ageing population and the replacement of immune birth cohorts on the burden of hepatitis A in the Netherlands.

Background: In populations in which the incidence of hepatitis A virus (HAV) infection has declined due to socio-economic improvements, better sanitation and hygiene, and vaccination, birth cohorts who have long-term immunity through exposure early in life are now being replaced by non-immune cohorts, meaning that more cases in the elderly may occur in future. Our goal was to qualitatively investigate the interaction of this cohort effect and demographic change (population ageing) on the estimated disease burden of HAV infection in the Netherlands.

Methods: We used dynamic MSIR (maternal immunity-susceptible-infectious-recovered) transmission and demographic models to simulate annual HAV incidence over the period 2000-2030, and estimated disease burden using the disability-adjusted life years (DALY) measure and a pre-defined disease progression model.

Prognosis of patients with breast cancer: causes of death and effects of time since diagnosis, age, and tumor characteristics.

Purpose: The proportion of women living with a diagnosis of breast cancer in developed countries is increasing. Because breast cancer-specific deaths decrease with time since diagnosis, it is important to assess the burden of other causes of death in women diagnosed with breast cancer.

Methods: Different causes of death within 10 years from diagnosis were assessed in 12,850 women younger than 75 years of age with stage 1 to 3 breast cancer diagnosed in Stockholm and Gotland regions 1990 to 2006.

[Survey of the Council of Residents of the Italian Society of Hygiene (SItI) on the smoking habits of physicians training in Hygiene and Preventive Medicine.].

This study was conducted on a sample of physicians training in Hygiene and Preventive medicine to evaluate their: smoking habits, awareness of the effects of cigarette smoke on health and attitudes regarding antismoking legislation. Data was obtained through administration of an anonymous questionnaire. A total of 220 physicians were interviewed: 27% was found to be a smoker while 45% of smokers stated that they did not want to quit smoking.

Third Italian national survey on knowledge, attitudes, and sexual behaviour in relation to HIV/AIDS risk and the role of health education campaigns.

Aim: The survey, supported by the National Health Institute (ISS), investigates on sources of information for HIV/AIDS and sexual behaviour of the Italian general population.

Methods: The survey was carried out in four different Italian provinces with different geographical, social, and epidemiological patterns of HIV/AIDS: Bari, Milan, Parma, and Perugia. A self-administered questionnaire was used to interview a sample of 2000 people, aged 18-49 years, chosen using a quota-sampling, considering age, sex, and level of education.

[The evaluation process of public health action: the challenge of epidemiology].

This paper aims to focus the need of a correct use of epidemiology in the evaluation process of public health actions. It has been described the challenge of epidemiology, at first used mainly for aetiological studies but now much more involved in health services research. Then, considering the fact that in public health every act has to be judged on the basis of its suitability and efficacy, but also of the few financial resources available, the authors stated the importance of the identification of the actual role of the epidemiologists in the evaluation processes and, meanwhile, of their specific training programs.
