Abstract
Alzheimer's disease (AD) represents the most frequent type of dementia in elderly people. Two major forms of the disease exist: sporadic - the causes of which have not yet been fully understood - and familial - inherited within families from generation to generation, with a clear autosomal dominant transmission of mutations in Presenilin 1 (PSEN1), 2 (PSEN2) or Amyloid Precursors Protein (APP) genes. The main hallmark of AD consists of extracellular deposits of amyloid-beta (Aβ) peptide and intracellular deposits of the hyperphosphorylated form of the tau protein. An ever-growing body of research supports the viral infectious hypothesis of sporadic forms of AD. In particular, it has been shown that several herpes viruses (i.e., HHV-1, HHV-2, HHV-3 or varicella zoster virus, HHV-4 or Epstein Barr virus, HHV-5 or cytomegalovirus, HHV-6A and B, HHV-7), flaviviruses (i.e., Zika virus, Dengue fever virus, Japanese encephalitis virus) as well as Human Immunodeficiency Virus (HIV), hepatitis viruses (HAV, HBV, HCV, HDV, HEV), SARS-CoV2, Ljungan virus (LV), Influenza A virus and Borna disease virus, could increase the risk of AD. Here, we summarized and discussed these results. Based on these findings, significant issues for future studies are also put forward.

Abstract
OBJECTIVES Nasal sprays could be a promising approach to preventing respiratory tract infections (RTIs). This study explored lay people's perceptions and experiences of using nasal sprays to prevent RTIs to identify barriers and facilitators to their adoption and continued use. DESIGN Qualitative research. Study 1 thematically analysed online consumer reviews of an RTI prevention nasal spray. Study 2 interviewed patients about their reactions to and experiences of a digital intervention that promotes and supports nasal spray use for RTI prevention (reactively: at 'first signs' of infection and preventatively: following possible/probable exposure to infection). Interview transcripts were analysed using thematic analysis. SETTING Primary care, UK. PARTICIPANTS 407 online customer reviews. 13 purposively recruited primary care patients who had experienced recurrent infections and/or had risk factors for severe infections. RESULTS Both studies identified various factors that might influence nasal spray use including: high motivation to avoid RTIs, particularly during the COVID-19 pandemic; fatalistic views about RTIs; beliefs about alternative prevention methods; the importance of personal recommendation; perceived complexity and familiarity of nasal sprays; personal experiences of spray success or failure; tolerable and off-putting side effects; concerns about medicines; and the nose as unpleasant and unhygienic. CONCLUSIONS People who suffer disruptive, frequent or severe RTIs or who are vulnerable to RTIs are interested in using a nasal spray for prevention. They also have doubts and concerns and may encounter problems. Some of these may be reduced or eliminated by providing nasal spray users with information and advice that addresses these concerns or helps people overcome difficulties.

Abstract
OBJECTIVES Respiratory tract infections (RTIs) are extremely common, usually self-limiting, but responsible for considerable work sickness absence, reduced quality of life, inappropriate antibiotic prescribing and healthcare costs. Patients who experience recurrent RTIs and those with certain comorbid conditions have higher personal impact and healthcare costs and may be more likely to suffer disease exacerbations, hospitalisation and death. We explored how these patients experience and perceive their RTIs to understand how best to engage them in prevention behaviours. DESIGN A qualitative interview study. SETTING Primary care, UK. METHODS 23 participants who reported recurrent RTIs and/or had relevant comorbid health conditions were interviewed about their experiences of RTIs. Interviews took place as the COVID-19 pandemic began. Data were analysed using inductive thematic analysis. RESULTS Three themes were developed: Understanding causes and vulnerability, Attempting to prevent RTIs, Uncertainty and ambivalence about prevention, along with an overarching theme; Changing experiences because of COVID-19. Participants' understandings of their susceptibility to RTIs were multifactorial and included both transmission via others and personal vulnerabilities. They engaged in various approaches to try to prevent infections or alter their progression yet perceived they had limited personal control. The COVID-19 pandemic had improved their understanding of transmission, heightened their concern and motivation to avoid RTIs and extended their repertoire of protective behaviours. CONCLUSIONS Patients who experience frequent or severe RTIs are likely to welcome and benefit from advice and support regarding RTI prevention. To engage people effectively, those developing interventions or delivering health services must consider their beliefs and concerns about susceptibility and prevention.

Abstract
Background Guidelines emphasize prompt antiviral treatment in severe influenza patients. Although nearly a 50% of severe influenza present with pneumonia, the effect of early (≤ 2 days after illness onset) neuraminidase inhibitor (NAI) use on the clinical outcomes of influenza A-related pneumonia (FluA-p) has rarely been assessed. Furthermore, data about the administration of NAIs in the real-world management of Flu-p in China are limited. Methods Data of patients hospitalised with FluA-p from five teaching hospitals in China from 1 January 2013 to 31 December 2018 were reviewed retrospectively. The impact of early NAI therapy on the outcomes in FluA-p patients, and the indications of early NAI administration by clinicians were evaluated by logistic regression analysis. Results In total, 693 FluA-p patients were included. Of these patients, 33.5% (232/693) were treated early. After adjusting for weighted propensity scores for treatment, systemic corticosteroid and antibiotic use, a multivariate logistic regression model showed that early NAI therapy was associated with decreased risk for invasive ventilation [odds ratio (OR) 0.511, 95% confidence interval (CI) 0.312–0.835, p = 0.007) and 30-day mortality (OR 0.533, 95% CI 0.210–0.807, p < 0.001) in FluA-p patients. A multivariate logistic regression model confirmed early NAI use (OR 0.415, 95% CI 0.195–0.858, p = 0.001) was a predictor for 30-day mortality in FluA-p patients and a positive rapid influenza diagnostic test was the only indication (OR 3.586, 95% CI 1.259–10.219, p < 0.001) related to the prescription of early NAI by clinicians. Conclusions Early NAI therapy is associated with better outcomes in FluA-p patients. Improved education and training of clinicians on the guidelines of influenza are needed.

Abstract
BACKGROUND Influenza causes large outbreaks every year. Professionals outside healthcare, including social care staff and non-care giving roles, have a key role in protecting their clients and sustaining operational productivity through influenza vaccination. There has been little research on non-healthcare staff working with vulnerable people and those working in non-caregiving settings regarding influenza and influenza vaccination. AIMS To understand the practices, experiences, perceptions and motivations of local authority staff regarding influenza and influenza vaccination. METHODS Semi-structured focus groups were carried out with local authority staff in Gloucestershire. Transcripts were thematically analysed. RESULTS Participants tended to perceive influenza as a serious illness, where a person had a specific risk factor or during pandemics. They did not feel vulnerable unless they had previous experience of infection or had an underlying health condition. Motivation to vaccinate was based on previous experience of influenza, where they had a close family member at risk or when working directly with vulnerable clients. Beliefs about negative side effects of the vaccine were the strongest reason for vaccine refusal. Ease of access to vaccination through on-site clinics is key to uptake. Management are perceived as key motivators or blockers to vaccine uptake. CONCLUSIONS Workers outside healthcare settings do not feel vulnerable to influenza and have low motivation to vaccinate, unless they have previous experience of infection or an underlying health condition. Vaccination programmes must proactively address workers' beliefs and motivations to ensure their participation in flu vaccination programmes.

Abstract
Background: Common cold and influenza result in an increased number of primary care consultations, significant work/school absences and cause a socio-economic burden. Laypeople’s perceptions and knowledge regarding common cold and influenza prevention is poorly understood and under-researched. Objectives: Our study explores laypeople’s knowledge of prevention of common cold and influenza across three European countries. Furthermore, it investigates if there is any distinction between prevention activities focussing on reasons impacting the attitude towards influenza vaccination as well as investigating cross-country variation. Methods: In total, 85 semi-structured individual interviews were performed across three European countries (Austria n = 31, Belgium n = 30, Croatia n = 24). Qualitative thematic content analysis was performed. Results: Most participants across all three countries made no distinction between the prevention of the common cold and influenza and referenced the same preventative measures for both conditions. They mainly expressed negative attitudes towards influenza vaccination possibly effective but only intended for high-risk groups (bedridden/older people, chronic patients or health workers). There were very few cross-country differences in results. Conclusion: The perception of health risk of contracting influenza and a primary healthcare physicians’ recommendation played an important role in shaping participants’ decisions towards vaccination. Primary healthcare physicians are invited to assess and if necessary adjust inappropriate prevention behaviour through their everyday patient consultations as well as add to the knowledge about influenza severity and influenza vaccination benefits to their patients.

Abstract
Background There is little research on laypersons’ perceptions regarding common cold and influenza, their symptomatic distinction and considerations of risk. This study investigates understanding of pathogenesis across three European countries and provides a knowledge base from which adequate prevention recommendations and treatment advice can be derived. Methods This is a qualitative research study. Semi-structured face-to-face interviews were conducted with 85 participants from three European countries (Austria n = 31, Belgium n = 30, Croatia n = 24) about their experiences, perceptions and risk considerations regarding the common cold and influenza. We performed a qualitative thematic content analysis. Results Three main themes were identified: common cold as harmless with individualistic symptoms; influenza as mainly distinguishable by fever, confinement to bed and severity of symptoms, but description about onset and duration are diverse; and views on pathogenesis contain references to disease causing agents and circumstances. Overall we found that risk perception is based largely on personal experience and risk is assumed moderate for both diseases. Conclusions Study participants possessed a fairly good understanding of symptoms, differences and pathogenesis of common cold and influenza; but explanations integrated misconceptions, such as misinterpretation of fever, disease continuums, diverse onset ideas etc. Perceptions were largely based on lived experiences and interventions for prevention and treatment should be led by health care workers and focus on these issues. Basic consultations, awareness raising activities and other knowledge disseminations strategies should include aspects of communicableness and the self-limiting nature of both diseases. An informed understanding of both infectious diseases is crucial and may also increase influenza vaccination coverage in the three respective countries effectively.

Abstract
AbstractAcute respiratory infections cause significant morbidity and mortality accounting for 5.8 million deaths worldwide. In Australia, influenza-like illness (ILI), defined as cough, fever and fatigue is a common presentation in general practice and results in reduced productivity and lost working days. Little is known about the epidemiology of ILI in working-age adults. Using data from the ASPREN influenza surveillance network in Australia (2010–2013) we found that working-age adults made up 45.2% of all ILI notifications with 55% of samples positive for at least one respiratory virus. Viruses most commonly detected in our study included influenza A (20.6%), rhinovirus (18.6%), influenza B (6.2%), human meta-pneumovirus (3.4%), respiratory syncytial virus (3.1%), para-influenza virus (2.6%) and adenovirus (1.3%). We also demonstrated that influenza A is the predominant virus that increases ILI (by 1.2% per month for every positive influenza A case) in working-age adults during autumn–winter months while other viruses are active throughout the year. Understanding the epidemiology of viral respiratory infections through a year will help clinicians make informed decisions about testing, antibiotic and antiviral prescribing and when the beginning of the ‘flu season’ can be more confidently predicted.

Beyond resistance: social factors in the general public response to pandemic influenza. BMC Public Health 2015; 15:436.

Abstract
Background Influencing the general public response to pandemics is a public health priority. There is a prevailing view, however, that the general public is resistant to communications on pandemic influenza and that behavioural responses to the 2009/10 H1N1 pandemic were not sufficient. Using qualitative methods, this paper investigates how members of the general public respond to pandemic influenza and the hygiene, social isolation and other measures proposed by public health. Going beyond the commonly deployed notion that the general public is resistant to public health communications, this paper examines how health individualism, gender and real world constraints enable and limit individual action. Methods In-depth interviews (n = 57) and focus groups (ten focus groups; 59 individuals) were conducted with community samples in Melbourne, Sydney and Glasgow. Participants were selected according to maximum variation sampling using purposive criteria, including: 1) pregnancy in 2009/2010; 2) chronic illness; 3) aged 70 years and over; 4) no disclosed health problems. Verbatim transcripts were subjected to inductive, thematic analysis. Results Respondents did not express resistance to public health communications, but gave insight into how they interpreted and implemented guidance. An individualistic approach to pandemic risk predominated. The uptake of hygiene, social isolation and vaccine strategies was constrained by seeing oneself ‘at risk’ but not ‘a risk’ to others. Gender norms shape how members of the general public enact hygiene and social isolation. Other challenges pertained to over-reliance on perceived remoteness from risk, expectation of recovery from infection and practical constraints on the uptake of vaccination. Conclusions Overall, respondents were engaged with public health advice regarding pandemic influenza, indicating that the idea of public resistance has limited explanatory power. Public communications are endorsed, but challenges persist. Individualistic approaches to pandemic risk inhibit acting for the benefit of others and may deepen divisions in the community according to health status. Public communications on pandemics are mediated by gender norms that may overburden women and limit the action of men. Social research on the public response to pandemics needs to focus on the social structures and real world settings and relationships that shape the action of individuals.

Abstract
Physicians may be well equipped for the biological aspects of disease, but not for its psychosocial dimensions, an issue that has been absent in family medicine. The psychosocial aspects of the disease are the factors involved in how patients react to the disease, play a role in the expression of symptoms and disease, and have implications on the lives of patients. Moreover, the biological effects (specific) and psychosocial effects (non-specific) are not simply additive but interactive. Physicians should be aware of this hidden, essentially invisible patient psychosocial morbidity, and must incorporate bio-psychosocial interventions into routine medical care to be more effective. In addition, to consider these aspects in the context of care contributes to the distinctive elements of family medicine.
