Estimation of the epidemiological burden of human papillomavirus-related cancers and non-malignant diseases in men in Europe: a review

<p>Abstract</p> <p>Background</p> <p>The role of human papillomavirus (HPV) in malignant and non-malignant genital diseases in women is well known and the corresponding epidemiological burden has been widely described. However, less is known about the role of HPV in anal, penile and head and neck cancer, and the burden of malignant and non-malignant HPV-related diseases in men. The objective of this review is to estimate the epidemiological burden of HPV-related cancers and non-malignant diseases in men in Europe.</p> <p>Methods</p> <p>The annual number of new HPV-related cancers in men in Europe was estimated using Eurostat population data and applying cancer incidence rates published by the International Agency for Research on Cancer. The number of cancer cases attributable to HPV, and specifically to HPV16/18, was calculated based on the most relevant prevalence estimates. The annual number of new cases of genital warts was calculated from the most robust European studies; and latest HPV6/11 prevalence estimates were then applied. A literature review was also performed to retrieve exhaustive data on HPV infection at all anatomical sites under study, as well as incidence and prevalence of external genital warts, recurrent respiratory papillomatosis and HPV-related cancer trends in men in Europe.</p> <p>Results</p> <p>A total of 72, 694 new cancer cases at HPV-related anatomical sites were estimated to occur each year in men in Europe. 17,403 of these cancer cases could be attributable to HPV, with 15,497 of them specifically attributable to HPV16/18. In addition, between 286,682 and 325,722 new cases of genital warts attributable to HPV6/11were estimated to occur annually in men in Europe.</p> <p>Conclusions</p> <p>The overall estimated epidemiological burden of HPV-related cancers and non-malignant diseases is high in men in Europe. Approximately 30% of all new cancer cases attributable to HPV16/18 that occur yearly in Europe were estimated to occur in men. As in women, the vast majority of HPV-positive cancer in men is related to HPV16/18, while almost all HPV-related non-malignant diseases are due to HPV6/11. A substantial number of these malignant and non-malignant diseases may potentially be prevented by quadrivalent HPV vaccination.</p

Competitive universities need to internationalize learning: perspectives from three European universities

The process of restructuring European universities in order to harmonize their educational systems is rapidly approaching a key milestone as 2010 looms large on the horizon. This paper describes an approach to the European Higher Education Area (EHEA) based on a real case study of students that belong to five European Universities (University of Burgos, Technical University of Valencia, University of Valladolid, University of Basque Country and University of Applied Sciences Cologne). The objective of this paper is two-fold: on the one hand, to analyze from the student’s point of view how they value the restructuring of teaching as a result of the Bologna process and what are the implications for students with regards to both their academic qualifications and their future incorporation into the labour market; and, on the other hand, to deduce from the results obtained recommendations which may help to guide teachers towards successful internationalization and collaboration between interuniversity networks, as well as achieving greater standards of quality within university teaching. Only this would permit an environment in which students are capable of developing the necessary competences, and put into practice learning outcomes. The results show that students value communication, innovative proposals and cooperation between universities; the internationalization of knowledge between universities has been positively accepted and this has motivated research to place a stronger focus on this aspect; it impacts strongly on scientific productivity, improves the quality of education offered by the teaching staff, and leads to greater student mobility. This strategy is intrinsically linked to learning from local experiences shared by members of the same university as well as from more global experiences made available through inter-university networks. It implies being willing to listen, to communicate, to engage in dialogue and means that we must seek to understand the potential contributions from teachers, staff and students that make up each university.Peer Reviewe

Impact of the bacterial nasopharyngeal microbiota on the severity of genus enterovirus lower respiratory tract infection in children: A case-control study

Introduction: Rhinoviruses (RV) and enteroviruses (EV) are among the main causative etiologies of lower respiratory tract infection (LRTI) in children. The clinical spectrum of RV/EV infection is wide, which could be explained by diverse environmental, pathogen-, and host-related factors. Little is known about the nasopharyngeal microbiota as a risk factor or disease modifier for RV/EV infection in pediatric patients. This study describes distinct nasopharyngeal microbiota profiles according to RV/EV LRTI status in children. Methods: Cross-sectional case-control study, conducted at Hospital Sant de Déu (Barcelona, Spain) from 2017 to 2020. Three groups of children <5 years were included: healthy controls without viral detection (Group A), mild or asymptomatic controls with RV/EV infection (Group B), and cases with severe RV/EV infection admitted to the pediatric intensive care unit (PICU) (Group C). Nasopharyngeal samples were collected from participants for viral DNA/RNA detection by multiplex-polymerase chain reaction and bacterial microbiota characterization by 16S rRNA gene sequencing. Results: A total of 104 subjects were recruited (A = 17, B = 34, C = 53). Children's nasopharyngeal microbiota composition varied according to their RV/EV infection status. Richness and diversity were decreased among children with severe infection. Nasopharyngeal microbiota profiles enriched in genus Dolosigranulum were related to respiratory health, while genus Haemophilus was specifically predominant in children with severe RV/EV LRTI. Children with mild or asymptomatic RV/EV infection showed an intermediate profile. Conclusions: These results suggest a close relationship between the nasopharyngeal microbiota and different clinical presentations of RV/EV infection.This project is supported by the Spanish National Health Institute Carlos III (Grant id.

Quantifying the under-reporting of uncorrelated longitudal data: the genital warts example

Abstract Background: Genital warts are a common and highly contagious sexually transmitted disease. They have a large economic burden and affect several aspects of quality of life. Incidence data underestimate the real occurrence of genital warts because this infection is often under-reported, mostly due to their specific characteristics such as the asymptomatic course. Methods: Genital warts cases for the analysis were obtained from the Catalan public health system database (SIDIAP) for the period 2009-2016. People under 15 and over 94 years old were excluded from the analysis as the incidence of genital warts in this population is negligible. This work introduces a time series model based on a mixture of two distributions, capable of detecting the presence of under-reporting in the data. In order to identify potential differences in the magnitude of the under-reporting issue depending on sex and age, these covariates were included in the model. Results: This work shows that only about 80% in average of genital warts incidence in Catalunya in the period 2009-2016 was registered, although the frequency of under-reporting has been decreasing over the study period. It can also be seen that this issue has a deeper impact on women over 30 years old. Conclusions: Although this study shows that the quality of the registered data has improved over the considered period of time, the Catalan public health system is underestimating genital warts real burden in almost 10,000 cases, around 23% of the registered cases. The total annual cost is underestimated in about 10 million Euros respect the 54 million Euros annually devoted to genital warts in Catalunya, representing 0.4% of the total budget

Estimating body mass of sperm whales from aerial photographs

We wish to thank Fundación Biodiversidad for supporting COLCA project and all the ecovolunteers involved in the fieldwork of the Balearic Sperm Whale project. We are grateful to OceanCare (Switzerland) for their continuous support of the sperm whale research and conservation activities of the PCRI since 2008 and to Prof. Kostas Kostarelos and the University of Manchester for organizing the crowd-funding project “Nanowhales” to cofund the research expedition of 2019 along the Hellenic Trench. This paper represents HIMB and SOEST contribution nos. 1903 and 11568, respectively.Body mass is a fundamental feature of animal physiology. Although sperm whales (Physeter macrocephalus) are the largest toothed predators on earth, body mass is seldom included in studies of their ecophysiology and bioenergetics due to the inherent difficulties of obtaining direct measurements. We used UAV‐photogrammetry to estimate the weight of free‐ranging sperm whales. Aerial photographs (23 calves, 11 juveniles, 55 nonmother adults, 13 mothers) were collected in the Eastern Caribbean and Mediterranean Sea during 2017–2020. Body length, widths, and heights (dorso‐ventral distance at 5% increments) were measured from dorsal and lateral photographs, while body volume was calculated using an elliptical model. Volume varied noticeably (12.01 ± 4.79 m3) in larger animals (>8 m), indicating fluctuations in body condition of adults and mothers. Volume was converted to mass, using tissue‐density estimates from catch data, animal‐borne tags, and body‐tissue composition. Average total body density ranged from 834 to 1,003 kg/m3, while the weight predictions matched with existing measurements and weight‐length relationships. Our body‐mass models can be used to study sperm whale bioenergetics, including inter‐ and intraseasonal variations in body condition, somatic growth, metabolic rates, and cost of reproduction.Publisher PDFPeer reviewe

Exploring self-care and cervical cancer prevention attitudes and practices among Moroccan and Pakistani immigrant women in Catalonia, Spain: a comparative qualitative study

BackgroundSelf-care and preventive health strategies may trigger health inequities when individuals' cultural values and health beliefs are not fully understood and considered. In the case of cervical cancer (CC) screening programs immigrant women have shown lower attendance compared with native women, which increases the risk of late diagnosis and, consequently, a lower probability of survival. HPV self-sampling for CC screening has been recently added to the World Health Organization's (WHO) list of self-care interventions as a promising tool to reduce this disparity and improve screening coverage. In Catalonia, Spain, the introduction of HPV self-sampling as a part of the new population-based CC screening program, is a significant step. However, there is a lack of research addressing self-care and prevention among immigrant populations in this region. This study aims to fill this gap exploring self-care and prevention attitudes and practices among Moroccan and Pakistani women.MethodsWe conducted focus groups and individual interviews with 36 Moroccan and 37 Pakistani women in Barcelona, Spain. The topic guide of the focus groups included case vignettes to stimulate the discussion and a semi-structured questionnaire was used for the interviews.ResultsOur findings show that most Moroccan and Pakistani women do not prioritize self-care and prevention. They seek care for symptom treatment rather than disease prevention. In this sense, they reported not having the habit of doing regular check-ups and their self-care and prevention attitudes and practices seemed to be conditioned by cultural values. The implementation of an effective call and recall system could enhance the engagement of these populations with CC screening services.ConclusionThis study provides evidence on how universal concepts of self-care and prevention may not aligned with more collectivist societies, emphasizing the limited applicability and motivation of global self-care interventions guidelines for individuals with different cultural backgrounds and values. Therefore, the successful implementation of CC screening programs or any other self-care intervention requires the adoption of culturally appropriate strategies
