Influenza is a highly contagious viral respiratory disease that affects million of people worldwide each year. Annual vaccination is recommended by the World Health Organization with the goal of reducing influenza severity and limiting transmission through elicitation of antibodies targeting the hemagglutinin (HA) glycoprotein. The antibody response elicited by current seasonal influenza virus vaccines is predominantly strain-specific, but pre-existing influenza virus immunity can greatly impact the serological antibody response to vaccination. However, it remains unclear how B cell memory is shaped by recurrent annual vaccination over the course of multiple seasons, especially in high-risk elderly populations. Here, we systematically profiled the B cell response in young adult (18–34 year old) and elderly (65+ year old) vaccine recipients that received annual split inactivated influenza virus vaccination for 3 consecutive seasons. Specifically, the antibody serological and memory B-cell compartments were profiled for reactivity against current and historical influenza A virus strains. Moreover, multiparametric analysis and antibody landscape profiling revealed a transient increase in strain-specific antibodies in the elderly, but with an impaired recall response of pre-existing memory B-cells, plasmablast (PB) differentiation and long-lasting serological changes. This study thoroughly profiles and compares the immune response to recurrent influenza virus vaccination in young and elderly participants unveiling the pitfalls of current influenza virus vaccines in high-risk populations.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin’s lymphoma (NHL) in adults. Epstein–Barr virus (EBV) positive DLBCL of the elderly was defined by the World Health Organization (WHO) in 2008, it was restricted only to patients older than 50 years old, and it was attributed to immunesenescence associated with physiological aging. After the description of EBV-associated DLBCL in children and young adults, the WHO redefined the definition, leading to the substitution of the modifier “elderly” with “not otherwise specified” (EBV + DLBCL, NOS) in the updated classification, and it is no more considered provisional. The incidence of EBV + DLBCL, NOS varies around the world, in particular influenced by the percentage of EBV+ cells used as cut-off to define a case as EBV-associated. EBV has effect on the genetic composition of tumor cells, on survival, and at the recruitment of immune cells at the microenvironment. In this review, the role of EBV in the pathogenesis of DLBCL is discussed.

The swine-origin new influenza variant A(H1N1) emerged in 2009 and changed the epidemiology of the 2009/2010 influenza season globally and at national level. Aims: The aim of the authors was to analyse the cases of two influenza seasons. Methods: The Medical and Health Sciences Centre of Debrecen University has 1690 beds with 85 000 patients admitted per year. The diagnosis of influenza was conducted using real-time polymerase chain reaction in the microbiological laboratories of the University and the National Epidemiological Centre, according to the recommendation of the World Health Organization. Results: The incidence of influenza was not higher than that observed in the previous season, but two high-risk patient groups were identified: pregnant women and patients with immunodeficiency (oncohematological and organ transplant patients). The influenza vaccine, which is free for high-risk groups and health care workers in Hungary, appeared to be effective for prevention, because in the 2010/2011 influenza season none of the 58 patients who were administered the vaccination developed influenza. Conclusion: It is an important task to protect oncohematological and organ transplant patients. Orv. Hetil., 2012, 153, 649–654.

StreszczenieB-komórkowe agresywne chłoniaki nieziarnicze (B-cell non-Hodgkin lymphoma – B-NHL) to heterogenna grupa nowotworów układu chłonnego, wywodząca się z obwodowych limfocytów B. Aberracje cytogenetyczne towarzyszące B-NHL to najczęściej translokacje onkogenów takich jak MYC, BCL2, BCL6 w okolice genowych loci dla łańcuchów ciężkich lub lekkich immunoglobulin. W niektórych przypadkach dochodzi do wystąpienia kilku wymienionych aberracji jednocześnie, tak jak w przypadkach przebiegających z równoczesną translokacją genów MYC i BCL2 (double hit), niekiedy także z obecnością rearanżacji BCL6 (triple hit). Takie chłoniaki cechuje szczególnie agresywny przebieg kliniczny. Obecnie molekularna diagnostyka cytogenetyczna przy użyciu techniki fluorescencyjnej hybrydyzacji in situ (FISH) oraz, w niektórych przypadkach, aCGH jest niezbędnym narzędziem rozpoznawania, klasyfikowania i oceny stopnia zaawansowania agresywnych, nieziarniczych chłoniaków B-komórkowych. Technika mikromacierzy CGH (aCGH) była kluczowym elementem wyróżnienia prowizorycznej grupy chłoniaków Burkitt-like z aberracją chromosomu 11q (Burkitt-like lymphoma with 11q aberration – BLL, 11q) w najnowszej klasyfikacji nowotworów układu chłonnego Światowej Organizacji Zdrowia (World Health Organization – WHO) z 2016 r. Omówione zostaną sposoby różnicowania na poziomie cytogenetycznym takich chłoniaków jak: chłoniak Burkitta (Burkitt lymphoma – BL), chłoniak rozlany z dużych komórek B (diffuse large B-cell lymphoma – DLBCL) oraz 2 nowych jednostek klasyfikacji WHO 2016, czyli chłoniaka z komórek B wysokiego stopnia złośliwości z obecnością translokacji MYC i BCL2 i/lub BCL6 (high-grade B-cell lymphoma HGBL, with MYC and BCL2 and/or BCL6 translocations) oraz chłoniaka BLL, 11q.

Influenza is a highly known contagious viral infection that has been responsible for the death of many people in history with pandemics. These pandemics have been occurring every 10 to 30 years in the last century. The most recent global pandemic prior to COVID-19 was the 2009 influenza A (H1N1) pandemic. A decade ago, the H1N1 virus caused 12,500 deaths in just 19 months globally. Now, again, the world has been challenged with another pandemic. Since December 2019, the first case of a novel coronavirus (COVID-19) infection was detected in Wuhan. This infection has risen rapidly throughout the world; even the World Health Organization (WHO) announced COVID-19 as a worldwide emergency to ensure human health and public safety. This review article aims to discuss important issues relating to COVID-19, including clinical, epidemiological, and pathological features of COVID-19 and recent progress in diagnosis and treatment approaches for the COVID-19 infection. We also highlight key similarities and differences between COVID-19 and influenza A to ensure the theoretical and practical details of COVID-19.

Abstract Healthy ageing is a public health problem globally. In Europe, the dependency ratio of the elderly is expected to increase by 21.6 per cent to 51.2 per cent in 2070. The World Health Organization (WHO) study on healthy ageing started in 2002 as a concept whereby all people of all ages should be able to live in a healthy, safe and socially inclusive way. The aim of this study is to present preliminary results of the project Identification of Determinants of Healthy Ageing in Italy (IDAGIT) that aimed to collect data on the active and healthy ageing of the Italian population aged over 18 using the conceptual framework of the WHO's ageing model. To link the determinants of the IDAGIT studies to those of the WHO model, we performed a confirmatory factor analysis which reported these variables as significant (in order of factor loading): smoking, cognition score, comorbidity, outdoor built environment, participation, working expertise and income. Considering comorbidity, 83.8 per cent of the sample declared not having any chronic diseases or to have only one, and regarding neurological diseases, only nine people had received a diagnosis of stroke. Regarding gender, the personal determinants and physical and social environments did not result in statistically significant differences, whereas we found statistical differences between the aged groups in all variables analysed. These results provide a first bio-psycho-social perspective on ageing in the Italian population.

RESUMO Objetivo Avaliar, por meio de questionários padronizados, a qualidade de vida de idosos com deficiência auditiva diagnosticada que utilizam ou não a prótese auditiva (AASI) e de idosos sem queixa auditiva. Método Trata-se de um estudo transversal, com amostra não probabilística, distribuída em três grupos divididos da seguinte forma: 30 idosos com perda auditiva diagnosticada e com indicação para uso do aparelho de amplificação sonora individual (AASI), mas que ainda não faziam uso da prótese; 30 idosos com deficiência auditiva que usavam o AASI; e 30 idosos sem queixa auditiva. Os participantes completaram um questionário que investigava dados sociodemográficos e familiares, o Hearing Handicap Inventory for the Elderly Screening Version (HHIE-S) e o World Health Organization Quality of Life - versão breve (WHOQOL-Breve). Além das análises descritivas dos dados, foram realizados testes para comparação dos três grupos, aplicando-se a análise de variância (ANOVA) e o teste post hoc de Bonferroni. Resultados Os três grupos se diferenciaram significativamente em todos os domínios de qualidade de vida. O grupo de idosos com perda auditiva diagnosticada e com indicação para uso do AASI apresentou menores escores que o grupo de idosos com deficiência auditiva que usavam o AASI e que o grupo de referência. O grupo com AASI apresentou os melhores resultados de qualidade de vida. Conclusão A perda auditiva afeta a qualidade de vida do idoso. O uso efetivo da prótese auditiva é benéfico a esta população, melhorando suas condições de vida e saúde.

Criminological concerns with the victimization of the elderly has developed parallel to, and independently of, the elder abuse debate. Criminologists have traditionally been concerned with the commission of acts against the older person in public as opposed to private space. A further hindrance to criminological enquiry is the practice of defining elder abuse in terms of victim needs, rather than of basic human rights. There has been no neat evolutionary process from positive treatment of the elderly, attributed to some golden age in the past to their increasing present victimization rates globally. Elder victimization is a long way from the simplistic notions of “granny battering.” There is general agreement among scholars that older people regularly suffer victimization in private space—in the household and in care institutions. They regularly experience multiple forms of abuse. One can attribute some of these experiences to major social changes as declining family support for older people diminishes and the proportion of young to old decreases. The World Health Organization (WHO) states that as the global population ages, the number of people aged sixty years and older is estimated to reach 1.2 billion worldwide by 2025. More pointedly, the longevity is also inextricably linked to the maltreatment of the global old. In particular, we have seen offenders apprehended in transgressions against the young, women, and ethnic minorities but have yet to see an active criminal justice response concerned with the experience of elder victimization. The discipline’s reluctance to recognize elder victimization is associated with it commonly being labeled as victimization by intimates, and to be understood through the lenses of psychology and psychiatry rather than through a criminal justice model. Care and individual needs of the elderly have been the traditional focus, rather than social justice, reason, and rights. Justice and rights involve choice and free will. Older people are not simply passive recipients of other people’s actions—they resist their victimization and often fight back. This article is a critical exposition of the sources available on elders abused as part of a larger account of the experience of older people worldwide. In particular, the reader is reminded that this article is limited due to publishing word constraints. Therefore, it provides a balanced, limited overview of the major literature and research available in the Western context. More pointedly, the literature cited here is intended to reflect on recent scholarship considered to have the potential of adding to the debate in criminology and elder victimization. Given that the study of elder abuse is still in its infancy in the discipline of criminology, this article is therefore necessarily interdisciplinary.

BackgroundDecline in social functioning occurs in individuals who later develop psychosis.AimsTo investigate whether baseline differences in disability are present in those who do and those who do not make a transition to psychosis in a group clinically at high risk and whether disability is a risk factor for transition.MethodProspective multicentre, naturalistic field study with an 18-month follow-up period on 245 help-seeking individuals clinically at high risk. Disability was assessed with the Disability Assessment Schedule of the World Health Organization (WHODAS–II).ResultsAt baseline, the transition group displayed significantly greater difficulties in making new friends (z =−3.40, P = 0.001), maintaining a friendship (z =−3.00, P = 0.003), dealing with people they do not know (z =−2.28, P = 0.023) and joining community activities (z =−2.0, P = 0.05) compared with the non-transition group. In Cox regression, difficulties in getting along with people significantly contributed to the prediction of transition to psychosis in our sample (β = 0.569, s.e. = 0.184, Wald = 9.548, P = 0.002, hazard ratio (HR) = 1.767, 95% CI 1.238–2.550).ConclusionsCertain domains of social disability might contribute to the prediction of psychosis in a sample clinically at high risk.
