As noted above, there is some evidence to suggest that social wellbeing and optimism for the future is particularly at risk during economic hard times (Clark & Heath, 2014; Elder, 1999; Lau et al., 2008) , yet research in this area has been relatively limited in the number of domains explored. The nature of the LSAY data, four birth cohorts measured roughly three years apart, allows us to compare the influence of the GFC at two distinct ages in the post high-school transition period (i.e., age 19 and 22). We were able to overcome limitations in previous research via the use of multiple cohorts of longitudinal data to explore the influence of the GFC at two different ages in one general and 11 domain specific measures of wellbeing.

cord-003244-abs3tc3r	2018	In 1978, the national Expanded Program on Immunization (EPI) in China started to implement a standard schedule for the routine administration of one dose of measles-containing vaccine (MCV1) among children between 8 and 24 months of age. In the present study, we compared the age-specific R of measles infections between different age groups by using laboratory and clinically confirmed data collected from 2009 to 2016. The R values estimated for children aged 7-15 years were low across the study period in general, even though the values also increased since 2012, indicating that primary and secondary school students had a limited contribution to measles transmissions. In this study, we compared the age-specific R of measles infections between different age groups, using laboratory and clinically confirmed data from 2009 to 2016 for Guangdong Province.

cord-005097-6xkx9a56	2006	The present article aims at outlining the impact of infectious diseases on the elderly and summarizing the progress made in the field of vaccinations of the elderly and how age-related changes within the immune system contribute to the decreased efficacy of vaccines. The following paragraphs will now deal with the most important infectious diseases that threaten the elderly population and will present data on their occurrence, vaccine availability and efficacy, vaccination coverage and current health authority recommendations. This live-attenuated VZV vaccine, which is 14-times more potent than the currently available vaccines that prevent chickenpox, has specifically been developed to protect the reactivation of herpes zoster in elderly people [28, 29] . The frequent occurrence and severity of infectious diseases seen in the elderly is mostly related to an age-related decline in the functions of the immune system that also negatively influences the production of protective antibody levels after vaccination.

The influence of sex, underlying disease and single organ failure was analyzed using the Fischer''s exact test, the influence of additional organ failure on mortality was tested with the Cochran-Mantel-Haenszet statistics.
cord-007084-4niom5mw	1987	Cholesterol side-chain cleavage enzyme activity, the rate-limiting enzyme in corticosterone biosynthesis, was measured in adrenal mitochondria isolated from 2-, 12-, and 18-month-old male Sprague-Dawley rats. Under basal conditions (without 25-hydroxycholesterol), cholesterol side-chain cleavage activity (expressed as nanomoles of pregnenolone produced per min mg protein" 1 ) increased (P < 0.001) from a mean (±SE) of 0.43 ± 0.06 in 2-month-old rats to 1.26 ± 0.11 and 1.51 ± 0.06 in the 12-and 18-month-old rats, respectively. Accordingly, we measured cholesterol side-chain cleavage, 3/3-HSD, 21-hydroxylase, 11/3-hydroxylase activities, and cytochrome P450 contents in appropriate mitochondrial and microsomal fractions of adrenals from 2-, 12-, and 18-month-old rats. Results of the present study also suggest that the decline in steroidogenesis observed in adrenocortical cells isolated from senescent rats is not related to a reduction in cholesterol side-chain cleavage activity or other steroidogenic responses, as measured in vitro in isolated subcellular components.

Mild to moderate focal chronic interstitial myocarditis occurred frequently in rats less than 6 mo old and then decreased in incidence with increasing age. These two lesions were not always coincidental, but one or both appeared to be the predecessor of interstitial fibrosis, >vhich was first seen at 6 to 12 mo, and increased in incidence and degree with age. The most frequent lesion was bile duct hyperplasia, which increased in incidence and severity with age. A wide variety of pathology was found and tabulated, and many lesions were found to increase in severity and incidence with age.

The balance between reaching the ambitious redistribution goals and minimising labour supply distortions is achieved with tax-fi nanced, income tested basic pensions, income-tested basic pensions and a strong link between wage income and accrued pensions for middle-and high-income workers in the earnings-related schemes. By law, the earnings-related pension scheme follows the defi ned benefi t rule, where contribution rates adjust to shocks that weaken the contribution base or increase expenditures. Key elements were the harmonisation of the benefi t rules of different earnings-related schemes, a tighter link between earned income and accruals, introduction of fl exible old age retirement, gradual abolishment of several early retirement schemes and the introduction of a link between life expectancy of the retiring cohort and the pensions.

Patients'' age, sex, risk group, CDC stage, CD4 count, indication for therapy, complication rate and response to treatment are described. Fifty-eight patients (34 male, 24 female) ranging in age from 15 to 65 years (Mean + SD = 28.4 + 10.8) were included in the study. Among these 48 patients (mean age 68.0+12.7), after controlling for age and for the duration and continuity of subsequent antipsychotic treatment, increasing duration of initially untreated psychosis was associated with greater severity of negative symptoms (p<0.005) and with lower scores on the MMSE (p<0.05) but not with executive dysfunction on the EXIT (p=0.3).

cord-016301-vqmqnipq	2011	Current success in transplanting kidneys into older recipients has quieted misconceptions within medical communities and the general public, among them the erroneous belief that advanced age alone prevents a successful surgical outcome, that the elderly patient with ESRD has a very limited life expectancy, and thus cannot receive a transplant, and that older recipients have poor results based upon outdated information from the previous era of transplantation and immunosuppression. While ECD kidneys carry a relative risk of graft failure greater than 1.7 compared to a reference group of donors aged 10-39 years without any of the above three conditions, elderly recipients of ECD kidneys were found to have a survival benefit compared with waiting-list candidates (RR = 0.75; 95% CI 0.65-0.86; p < 0.0001) [8] . One study evaluated 91 transplant recipients over the age of 60 over a 13-year span and reported a 10-year patient survival of 35% in the elderly group and 60% in the younger patients ( p < 0.05).

This may lead to an increased morbidity and mortality and to a spreading ofthe disease, in particular within institutionalized elderly persons.P Further difficulties include the increased emergence of new, multiple drug-resistant strains with higher rransmissibiliry," the poor efficacy of the current bacille Calmette Guerin (BCG) vaccine in protecting adults and elderly people from pulmonary Infection" and the increased risk ofTB co-infection in HIV positive patients." However, in the past few years, several TB vaccine candidates have entered phase I clinical trials, including adjuvanted subunit vaccines as well as improved live recombinant strains of the current BCG vaccine (Table 1 ).
cord-017916-wh708hes	2008	Some nutritional factors (zinc and selenium) may remodel these changes leading to a possible escaping of diseases with subsequent healthy ageing, because they are especially involved in improving immune functions as well as antioxidant defense. Therefore, the interrelationships between zinc and MT is crucial in maintaining the immune response especially in ageing where the production of proinflammatory cytokines is chronic leading to a constant presence of inflammatory status coupled with low intracellular zinc ion bioavailability (Mocchegiani et al. All these "in vitro" and "in vivo" studies in ageing, some age-related diseases, and syndrome of accelerated ageing (nude mice, nTx mice, Down''s Syndrome) demonstrate the pivotal role played by zinc supplementation in maintaining or improving global immune response and in fighting the oxidative stress, strengthen by findings observed in human centenarians.
cord-018387-ci5wx26t	2019	Several lifestyle strategies, such as intervening to provide an adequate diet and physical and mental activity, have been shown to result in improved immune and neuroprotective functions, a decrease in oxidative stress and inflammation, and a potential increase in individual longevity. Thus, zinc deficiency may adversely affect the immunological status, increase oxidative stress, lead to the generation of inflammatory cytokines, and influence the progression of many chronic diseases, including atherosclerosis, neurological disorders, autoimmune diseases, age-related degenerative diseases, and various malignancies [5] . It has been suggested that aging is associated with chronic innate immune activation and significant changes in the functions of monocytes and macrophages, which may have implications for increased low-grade chronic inflammation and for the development of age-related diseases [61] . Evidence that long-term behavioral changes, including nutritional intervention and reduced energy intake together with physical activity, may prevent, improve, or even reverse age-related impairments in immune function continues to accumulate [2] .
cord-018449-4vdqq961	2016	These are the real reason that the end of the Bronze Age in the Near East was called either the "catastrophe" or the "collapse" due to its short time frame of 50 years, the mass migration of the general population and the "Sea Peoples" plus the abandonment of cities such as Hattusa, the capital of the Hittite Empire c.1200 bce. Any historian trying to fi nd the cause of the end of the Bronze Age and the Hittite Empire must explain: the short time frame of approximately 50 years, when it occurred between 1200-1150 BCE ; the mass migrations not only of normal people but also of the "Sea Peoples"; and the fact that so many large cities, such as the Hittite capital Hattusa, were simply abandoned and not destroyed or occupied by raiders or invaders.
cord-020694-zoy49483	2020	In order to compare the age specific incidence of opportunistic versus non-opportunistic infections, we selected pathogens that are sufficiently common globally, for whom there is good background epidemiological information including whether and with what frequency they inhabit the host body under normal conditions, whether a long-term carrier state is known, and whether they confer long-term immunity. We searched PubMed and Google Scholar for individual published reports giving age-class-specific incidence, in addition to available online data from Centers for Disease Control Bureau of Statistics. In the other pattern followed by 8 species and 12 pooled datasets, there was a significant negative trend in 6 with a 50% to 95% decrease in incidence between the 20 and over-60 age groups. The prediction specific to the declining immunity hypothesis that the incidence of externally acquired infections should also increase with age failed to obtain generalized support in epidemiological data.

cord-035015-slgywe0c	2020	Data is now showing that COVID-19 patients do have populations of T-cells displaying mitochondrial dysfunction, as well as altered mitochondrial markers in monocyteshinting that immune-metabolic phenotyping could be used to understand disease pathogenesis and possible treatments; this could include targeting mitochondria [32] . The underlying aetiology for "inflammaging" has long thought to be associated with mitochondrial dysfunction as suggested by Nick Lane in 2003 in his "double agent" theory [5] , and is now receiving renewed interest, for instance, in how decreasing mitochondrial function can reduce T-cell function and enhance immune senescence, as mitochondria are pivotal in metabolic reprogramming towards the Warburg effect [40] . Furthermore, as evidence indicates that many viruses, which most likely include SARs-CoV-2, modulate bioenergetics and redox in both the immune system and other cells they infect to enhance their own replication, they could potentially induce excessive stress in these systems if their mitochondria are already sub-optimally functional.
cord-103337-a1yidr4y	2020	title: Age differential analysis of COVID-19 second wave in Europe reveals highest incidence among young adults To understand the evolution of the ongoing wave, one should trace it back to its origin in the summer, when the incidence started to grow again after the effects of the strict restrictions that were imposed in the Spring faded out, which resulted in an increased number of local outbreaks and community transmission of COVID-19 in most of Europe. To elucidate if this pattern is characteristic of this region or if it is more general, we have collected data on the COVID19 incidence in 25 European countries aggregated by age groups during the period from 1 September to 27 October. These very robust and regular patterns of the incidence of the current second wave are a remarkable observation given that countries in Europe responded distinctly and at different times during the early stages of the pandemic.
cord-142389-t5swlp04	2020	We investigated this apparent discrepancy using age-stratified case and death reports [3] , and an age-dependent infection fatality rate (IFR). From this age-dependent IFR we predict the temporal evolution of the COVID-19associated deaths by delaying each age group''s observed weekly cases by two weeks and multiplying by the IFR (see supplementary material). The observed number deaths (black) in each age group matches well the predicted deaths calculated from the case numbers (color) using an age-dependent infection-fatality rate from a metaanalysis [4] . b. IFR calculation The overall goal is to estimate death numbers from past reported cases per age group and compare them to the observed number of deaths. c. Estimating the number of deaths from the reported SARS-CoV-2 cases The number of deaths is estimated by multiplying the published weekly number of reported cases in 5-years-wide age groups by the associated IFR (equation (2)).
cord-253182-s60vzf3q	2020	Major healthcare challenges involved with caring for the elderly in China include the management of chronic non-communicable diseases (CNCDs), physical frailty, neurodegenerative diseases, cardiovascular diseases, with emerging challenges such as providing sufficient dental care, combating the rising prevalence of sexually transmitted diseases among nursing home communities, providing support for increased incidences of immune diseases, and the growing necessity to provide palliative care for the elderly. The research agenda in response to rapid population ageing in China has been broad, covering areas including the study of the ageing process itself in laboratory and animal studies, to clinical-level studies of drugs or other treatments for common chronic diseases, and finally policy-level research for the care of the elderly in hospital, community and residential care settings, and its influence on health and social care policies . Major risk factors of the high prevalence of dental diseases in the elderly in China include the scarcity of dental health knowledge in the general population, low frequency of daily oral hygiene practices, insufficiency of dental care services, and unhealthy diet habits.
cord-254339-djmibi3a	2020	In particular, we build a new mathematical model and a new computational method to fit the data by using age classes dependent exponential growth at the early stage of the epidemic. We fit this model to the observed data and obtain a snapshot of the effective transmissions occurring inside the population at different times, which indicates where and among whom the disease propagates after the start of public mitigation measures. [17] also discuss age-related effects in the control of the COVID epidemic, and use statistical inference to fit an age-structured SIR variant to data; the model is then used to discuss the efficiency of different control strategies. One of the difficulties in fitting the model to the data is that the growth rate of the epidemic is different in each age class, which lead us to adapt our early method presented in Liu et al.
cord-254896-e6k1bp9n	2020	The observed age dependency of the proportions of registered COVID-19 deaths in relation to the population sizes in the age groups is approximately exponential, similar to the age dependency of the general age specific mortality rate. Comparing the infection fatality rate estimates reported in [3] with the normal annual mortality rates for Austria, we see parallels as well -the estimated risk of death with COVID-19 is for the majority of age groups roughly as high as the normal risk of dying within 1-2 years (Fig. 3 , black dots). We also observe that the number of those who have died in Austria with COVID-19 per population size in the respective age and sex group have a similar exponential age dependency as the estimated infection fatality rates (Fig. 2a, b and 3) .
cord-257765-ljt9rn8z	2020	Accounting for differences in the distribution of age, sex and relevant comorbidities yields substantial differences in the predicted IFR across 21 world regions, ranging from 0.11% in Western Sub-Saharan Africa to 1.07% for high-income Asia Pacific. To account for the likelihood of higher fatality rates in under-resourced health systems, we adjust the predicted IFRs for differences in the relative odds of infection fatality from childhood respiratory syncytial virus (RSV) between world regions as a proxy for local capacity to treat viral respiratory illnesses. We can test the validity of our core assumption, namely, that variation in age, sex and comorbidity distributions as well as health system capacity explain differences in IFRs across countries by comparing our predicted IFRs to independently measured IFRs. For this exercise, we consider all studies reporting either IFRs or infection rates for populations with available COVID-19 fatalities, which were listed in the systematic review by Meyerowitz-Katz and Merone 17 or retrieved through an online search on July 2.

cord-259971-e3h8pr1v	2020	Conclusions: The finding that the prevalence rates and the mean scores for stress, anxiety, and depression on standardized scales to decrease from younger to older subscribers is an interesting observation with potential implications for planning to meet mental health service needs during COVID-19. In an online survey of Chinese subjects, prevalence of generalized anxiety disorder and depressive symptoms was significantly higher in participants younger than 35 years than in participants aged 35 years or older [13] with age and amount of time spent focusing on COVID-19 identified as potential risk factors for psychological illness. On the other hand, older people tend to be less socially mobile than younger ones, thus possibly explaining their reported lower scores on rating scales for stress, anxiety, and depression during a pandemic lockdown. The trend for mean scores across the stress, depression, and anxiety scales to decrease in severity from younger to older age has potential implications for planning to meet mental health service needs during COVID-19.
cord-260797-tc3pueow	2020	In addition, we conduct extensive numerical simulations and conclude that heterogeneities in the contact network are important for a proper determination of the epidemic threshold, whereas the age-structure plays a bigger role beyond the onset of the outbreak. To bridge this gap, in this paper, we focus on analyzing the role that disease-independent heterogeneity in host contact rates plays in the spreading of epidemics in large populations under several scenarios, both numerically and analytically. A slightly better approximation is to divide the population into agegroups, given the demographic structure of the population, Fig 1B, and establish a different number of contacts between and within them (model M), which is the common approach currently used in the epidemic literature to model age-mixing patterns. Nevertheless, most network approaches focus only on determining the role that the difference in the number of contacts of the population has on the impact of disease dynamics but ignore other types of heterogeneities such as the age mixing patterns.

Through multivariate analysis of the causes of death in older patients, we found that male gender, diabetes mellitus, heart failure, chronic kidney disease, dementia, cancer, admission to intensive care unit, computed tomography finding compatible with COVID-19 were all significantly associated with mortality in entire cohort. The Centers for Disease Control and Prevention (CDC) reported that individuals older than age 65 comprise 17% of the total population in the United States, though they are responsible for 31% of infections, 45% of hospitalizations, 53% of intensive care unit (ICU) admissions and 80% of deaths caused by . Clinical characteristics and outcomes of older patients with coronavirus disease 2019 (COVID-19) in Wuhan, China (2019): a single-centered, retrospective study
cord-263650-jxkjn8ld	2020	Specifically, drawing on a broad understanding of care that is consistent with Fisher and Tronto (1990) ; also Tronto, 2013) , the purpose of our study was to explore and compare the relationships between culture and informal family care practices across three diverse ethno-cultural groups: Chinese, South Asians, and Latin Americans living in Vancouver, British Columbia, Canada. Adults self-identifying as Chinese, South Asian, and Latin American, and providing unpaid, informal care or support to someone over the age of 65 needing some level of assistance with activities of daily living, were invited to participate. Even only adult children like Argentinian Rossana pointed out that she had created networks from her family (husband, daughter, and grandchildren, among others) and paid companions as well as her 92-year-old mother''s long-time friends to provide support and care.
cord-264811-xbeipob9	2020	This study aims at assessing the impact of social distancing on the reduction of COVID-19 infected cases by constructing a mathematical model and using epidemiological data of incidences in Korea. An example of a scenario/policy-specific contact matrix of Seoul and Gyeonggi province-school closure with no social distancing, M C -is shown in Figure 3 ; a comparison with the equivalent version for Korea is provided in Figure S3 in Supplementary Section B. In the age-structured model developed in this study, we estimated the transmission rate by applying the contact matrix obtained from [25] to the actual incidence and population data for Seoul and Gyeonggi province. We estimated the transmission rate for each age group in seven distinct periods using the COVID-19 data and contact matrix for each age group and investigated the effect of social distancing on the control of the disease in the age-structured model under various scenarios.
cord-267664-vahd59z8	2020	Not surprisingly, the usual, despicable age criterion started to be implicitly adopted in the decisional algorithm for the allocation of scarce resources to the mounting number of patients. It is noteworthy that during the early crisis, the Società Italiana di Anestesia, Analgesia, Rianimazione e Terapia Intensiva (SIAARTI; Italian Society of Anesthesia, Analgesia, and Intensive Care) released clinical ethics recommendations for the allocation of treatment in exceptional resource-limited situations. Of course, the patient''s age… If we want to fight such an ageistic approach and replace the age criterion for the allocation of resources, we must have and propose a parameter more robust than age but equally easy-to-obtain, that can be used for critical and rapid decision-making. In settings where rationing of resources becomes a necessity and such preparation has not been made, medical staff or oversight organizations should implement ad hoc guidelines that incorporate key prognostic factors beyond age -most notably frailty, comorbidity, and functional status. Clinical ethics recommendations for the allocation of intensive care treatments, in exceptional, resource-limited circumstances
cord-274009-ew4diub5	2020	This study examined the impact of sheltering in place and social distancing among adults aged 60 and older during the 2020 outbreak of COVID-19 in the United States. Using convenience sampling respondents were asked to complete a web-administered survey to explore impact of social distancing on loneliness, stress, and behavioral changes. Social distancing has significant consequences on loneliness and health behaviors among adults in the United States, many of which differ by age group. The purpose of this study was to explore how adults aged 60 and older in the US are coping with social distancing and sheltering in place during the COVID-19 pandemic. These included doing more or less: sleeping, engaging in physical activity, smoking, drinking alcohol, using recreational drugs, eating, solitary activities, engaging in in-person activities, making/receiving phone calls, using social media, emailing, ending/receiving text messages, and spending time on the computer/tablet/phone. Those living alone were also significantly more likely to report that their loneliness had increased since social distancing (42.4%) compared those living with others (27.9%).
cord-274546-jswt3pun	2020	We fit this model to the observed data and obtain a snapshot of the effective transmissions occurring inside the population at different times, which indicates where and among whom the disease propagates after the start of the public measures. One of the difficulties in fitting the model to the data is that the growth rate of the epidemic is different in each age class, which lead us to adapt our early method presented in [9] . Here t ≥ t 0 is time in days, t 0 is the starting date of the epidemic in the model, S(t) is the number of individuals susceptible to infection at time t, I(t) is the number of asymptomatic infectious individuals at time t, R(t) is the number of reported symptomatic infectious individuals at time t, and U (t) is the number of unreported symptomatic infectious individuals at time t.

cord-280605-2i4gk7et	2020	With increasing age, the dynamics and proportion of lymphocytes and myeloid cells differ depending on the sex due to the differential expression of 144 genes of the immune response in men and women (71) . Anti-inflammatory effect of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and their biologically active metabolites (D and E Resolvinsmediators derived from omega-3 fatty acids, primarily EPA and DHA that block the production of proinflammatory mediators and regulate leukocyte trafficking to inflammatory sites) can be mediated through one of the mechanisms capable of reducing inflammation of RAW-264.7 cells and of primary intraperitoneal macrophages (105) . Exposure to various alarm signals induce an acute inflammation that, when associated with deleterious environmental and biological factors, potentiates chronic inflammation, which can be further promoted by excess ROS production and oxidative stress that results from mitochondrial dysfunction or NOX2 activity, leading to inflammaging and eventually to age-related disease.
cord-282839-3ii79g6j	2020	Thus, it seems clear that mitochondrial dysfunction is an important factor in the proinflammatory profile caused by the release of inflammatory cytokines produced by activation of NLRP3 inflammasome and other mechanisms over-activated in aging and in metabolic diseases. It seems clear that, mitochondrial dysfunction in diabetic patients contributes importantly to the low-grade inflammatory profile associated with this disease that is aggravated during aging and has been associated with higher severity in COVID-19 infection. Mediterranean diet, rich in plant foods, is associated with reduced risk of developing age-J o u r n a l P r e -p r o o f related chronic diseases by inducing protection against oxidative stress and improving mitochondrial activity that could be the cause of a reduced inflammation level (Tosti et al., 2018) . Mitochondrial dysfunction releases many damage signals to cytosol that end in the activation of inflammasome and the release of inflammatory cytokines that cause the chronic inflammation associated with aging and age-related diseases.
cord-285546-5tjhdczt	2020	title: The confounded crude case-fatality rates (CFR) for COVID-19 hide more than they reveal—a comparison of age-specific and age-adjusted CFRs between seven countries BACKGROUND: Crude case-fatality rates (CFRs) for COVID-19 vary widely between countries. We examined how the age distribution of the cases is responsible for the COVID-19 CFR differences between countries. METHODS: COVID-19 cases and deaths, by ten-year age-groups, were available from the reports of seven countries. The age-adjusted CFRs were computed by the direct method, using the combined number of cases in all seven countries in each age group as the standard population. CONCLUSIONS: The age structure of the cases explains much of differences in the crude CFRs between countries and adjusting for age substantially reduces this variation. The age-specific number of cases, number of deaths and the crude CFRs by country are given in Table 1 .
cord-288392-khjo6j8u	2020	This paper provides a quantifiable spatial indicators framework to assess local lived environments according to each Age-Friendly Cities and Communities (AFC) domain. The spatial measures used to assess this included: walkability (with and without footpaths); access to public open space; access to public transport; housing affordability; housing diversity; government owned dwellings (social housing); access to services for older people; libraries; universities of the 3rd Age; places of worship; volunteering; households with internet access; aged care facilities; and access to General Practitioners. Objective spatial measures of the lived environment are critical for the following reasons: to simplify assessments of AFC; to provide a foundation level of knowledge about the age-friendliness of an environment; to assist local and state government planning by informing and monitoring future actions and interventions needed to promote healthy ageing in communities; and to include older people into targets of the 2030 Sustainable Development Goals and the New Urban Agenda.
cord-291184-uza4orb8	2020	We find that starting from 60% horizontal confinement, an exit strategy on May 1st of confinement of individuals older than 60 years old and full release of the younger population results in 400 000 hospitalizations, 50 000 ICU cases, and 120 000 deaths in the 50-60 years old age group alone. 29 Here we develop an SIR type compartmental models for COVID-19 including both 30 symptomatic and asymptomatic, quarantined, and hospitalized while taking into 31 consideration differences by age groups. The timescales σ, γ, θ, and ξ, as well as the fractions p and w, are found by Markov 152 chain Monte Carlo (MCMC) fitting, with priors as given in Table 1 Fig. 4a shows the evolution of the compartments of exposed (E), asymptomatic (A), 166 symptomatic (I), and hospitalized (H), in linear scale. Collapse of health care system can be avoided if vertical 213 confinement is instored on people who are 60 or older, but at the expense of a significant 214 number of extra ICU cases for the 50-60 age bin.
cord-292024-ae7rauc6	2020	The increased numbers and activity of certain innate or innate-like immune cell subsets with aging might be considered host responses to compensate for the drastic decline in adaptive immune cell development and function [95] . Several studies have also indicated age-related functional changes in DCs, such as impaired expression of TLRs [115] ; decreased production of cytokines, chemokines, and IFN-a after TLR stimulation [112] [113] [114] [115] [116] ; and increased responses to self-antigen [117] . In the meantime, senescent T cells, analogously to other senescent cells arising with age in the body, produce large amounts of proinflammatory cytokines (a phenomenon called senescence-associated secretory phenotype, SASP) as stated by the inflammaging characteristics of the human immune system [141, 142] . Given the central role of Treg cells in immune homeostasis, age-related loss of Treg function would be predicted to render the host susceptible to excessive immunity, encountered in elderly humans as a syndrome of chronic low-grade inflammation [172] .
cord-294180-t5bncpo4	2020	It is interesting to highlight that both aging and chronic diseases are linked to an increase in levels of systemic inflammation, which could explain a potential common pathway between these factors and COVID-19. In this context, lifestyle and nutraceuticals arise as important prophylactic interventions to reduce the burden of baseline inflammation in older adults and consequently improve quality of life, mobility, cognition, mood, and metabolic and immune balances, especially during the pandemic. Vitamin D, or more specifically, 25hydroxyvitamin D [25 (OH) D], is an anti-inflammatory nutrient (41) , and reduces the activation of the renin-angiotensin system, preventing hypertension (42), besides its importance to bone and muscle, an inverse relationship is also observed between its levels and mortality risk in old adults (43) . Furthermore, reducing sedentary behavior and engaging in exercise may increasing the production of systemic anti-inflammatory cytokines and help to combat inflammation (63, 64) by increasing innate immune function (65) and decreasing the chronic inflammation related to various diseases (66) .
cord-294501-1nf98mpb	2020	Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is characterized by a high mortality of elderly men with age-related comorbidities. Consistent with this finding, the ability of DCs and macrophages to elicit CD8 + T cell response and proliferation and to release antiviral cytokines is impaired in elderly individuals [34] ; in parallel, these subjects are characterized by a reduced activity of plasmacytoid DCs, the main sources of type I IFNs, which underpin the antiviral response and provide the first-line sentinels in immune surveillance, also in the lung [35] . 4. In older men with age-related diseases, the aging-dependent reduction in ACE2 activity worsens SARS-CoV-2 infection outcomes Angiotensin-converting enzyme (ACE)2, the main SARS-CoV2 host cell receptor, plays a crucial role in virus entry into the cell, as previously demonstrated in SARS and NL63 human coronaviruses [41] . In these individuals, acute SARS-CoV-2 infection compounds their chronic, subclinical, aging-related proinflammatory state (inflamm-aging) which, together with immune senescence and the age-and gender-specific distribution of ACE2 in the airway epithelia, could blunt the antiviral response to inflammation.
cord-296494-6kn4mr04	2020	Bearing this in mind, it is quite likely, that if we have fewer complications, particularly severe ones (cardiac arrest, ventricular tachyarrhythmia, acute heart failure, acute coronary syndrome, haemorrhagic or massive ischaemic stroke), this integrated approach could cut down the elevated mortality in the highest risk group (cancer, COPD and oldest subjects with comorbidities), usually preceded by a multi-organ failure. In aged COVID-19 patients or with history of coronary artery disease (CAD) an acute coronary syndrome (ACS) can also be seen for plaque vulnerability in the presence of a pro-inflammatory state with cytokine release (71) but from the experience in animals, could it be plausible that any of them could be due to arteritis? The third aspect would be the combination of T2DM and Heart failure (HF) (the most frequent cardiac complication in any of the phases of the disease), which is present in a high percentage of patients, especially those at higher risk.

Variables used in this study included cat identification, sex, date of birth, breed, life insurance coverage, and diagnostic codes for cause of death. Age-standardized MRs (ASMR, which adjusts for differences in age distributions across groups or categories) have been calculated both for the whole period and yearly and are expressed as deaths per 10,000 CYAR (data on age category 9 o 10 years and over were amalgamated for standardization). Standard errors times 1.96 yielded 95% confidence intervals (95% CI) for ASMRs 8 and age category-specific MRs. 9 Age standardized MRs, and MRs, respectively, have been calculated crudely, yearly, by sex, breed group, breed, diagnostic category, diagnosis, and by combinations thereof as well as for withdrawal unrelated to death.

The same specimens were previously studied for rotaviruses, noroviruses, sapoviruses, adenoviruses, coronaviruses and aichivirus. As in the case of the respiratory tract, simultaneous presence of HBoV1 with other, previously established gastroenteritis viruses is common in faecal specimens (10, 12, 13) , and no clear connection between HBoV1 and AGE of children has been established (11, 13, 14) . We did a thorough work-up of most of the established gastroenteritis viruses including rotaviruses, noroviruses, sapoviruses, enteric adenoviruses, coronaviruses and aichivirus (astroviruses or bacterial pathogens were not studied) and found co-infections in 81.2% of all bocavirus-positive AGE cases.

cord-305743-rnfn6opa	2020	Aging is the primary risk factor for functional decline; thus, understanding and preventing disability among older adults has emerged as an important public health challenge of the 21st century. Given the aging US population, the disproportionately high prevalence of the metabolic syndrome in older adults is a significant public health concern, as it substantially increases the risk for cardiovascular disease J o u r n a l P r e -p r o o f Journal Pre-proof (CVD) [27] [28] [29] [30] and is associated with increased all-cause mortality, disability, CVD mortality, myocardial infarction, and stroke [31] . Age-related life changes that increase susceptibility to social isolation and loneliness includes changes in health status limiting functioning and mobility; changes in family structure (divorce, childless); death of friends, family members, and spouse; auditory and visual changes reducing the ability to communicate and interact; and resource reductions including healthcare access and quality of care [135] .
cord-306210-ny3vvu9h	2020	Furthermore, advancing age (from about 60 on), even in those older persons without any accompanying illnesses, is a strong and independent risk factor for pneumonia, need for an ICU bed and death from the virus. Recommendations include the Ministry of Health publishing clear guidelines as to risk factors and offering sensible advice on how to practice physical (not "social") distancing without exacerbating an older person''s sense of social isolation. Although we are dealing with a fast and erratically moving target, with the present situation in mind this paper will elucidate relevant issues and offer policy recommendations germane to when and how older persons can minimize risk and at some point in the future return to their pre-COVID-19 routine in Israel. A step-by-step proposal 1) With respect to the at-risk populations (those with relevant medical illnesses and older age), so far, even though the number of infected person is rising once again, at the date of writing (late October, 2020) the program recommended herein is still voluntary.

cord-309161-ceahghs1	2020	While there are myriad individual patterns of exposures, traumatic stress or material deprivation have larger effects early in life than when they occur at later periods; Early life adversity is predictive of a range of poor outcomes, including poor mental health, health behaviors, biomarkers of aging, and earlier disease onset (Deighton et al., 2018; Hughes et al., 2017) although plasticity is still possible (McEwen & Morrison, 2013) . Several of these basic mechanisms in immune cells have been associated with aspects of social stress, including systemic inflammation and shorter telomeres (Epel et al., 2004; Kiecolt-Glaser et al., 2011; Miller et al., 2008) poor mitochondrial function (Picard et al., 2018) , and accelerated epigenetic aging (Park et al., 2019; Wolf et al., 2018) . Stress resilience depends in part on the pre-existing level of reserve capacity, the positive protective factors of an organism, as well as the immediate adaptive psychological response to stressors (cognitive appraisals).
cord-309556-xv3413k1	2020	In aggregate, these analyses showed that the age-associated genes with functional roles in SARS-CoV are expressed in specific cell types of the human lung. Of note, the overlap between lung ageassociated genes and SARS-CoV-2 regulated genes was statistically significant across all 3 cell lines (Figure 6d-f) , suggesting a degree of similarity between the transcriptional changes associated with aging and with SARS-CoV-2 infection. Among the age-associated genes that were induced by SARS-CoV-2 infection, the majority of these genes increase in expression with age (Cluster 1) (Figure 6g-i) . To identify a consensus set of age-associated genes that are regulated by SARS-CoV-2 infection, we integrated the analyses from all 3 cell lines. By integrating these data with single cell transcriptomes of human lung tissue, we further pinpointed the specific cell types that normally express the age-associated genes.
cord-309809-zvh2k97q	2020	DISCUSSION AND IMPLICATIONS: Findings are consistent with the strength and vulnerability integration (SAVI) model, wherein older adults try to maintain positive emotional well-being; with middle-aged and older adults in the current study having experienced less negative impact on well-being. Even in non-crisis situations, regardless of age, higher levels of global perceived stress heighten a person''s negative affective response to stress (Scott et al., 2013) ; although, older adults in another study reported less of an increase in negative affect when faced with a daily stressor, compared to younger adults (Uchino, et al., 2006) . Consistent with previous findings on stress (Uchino, et al., 2006) , the current study found that when faced with a stressor, in this case a global pandemic, middle-aged and older adults may be better at regulating their emotions even when they perceive the stressor as disruptive.
cord-309885-6sjxi2et	2020	title: Age-Dependent Assessment of Genes Involved in Cellular Senescence, Telomere, and Mitochondrial Pathways in Human Lung Tissue of Smokers, COPD, and IPF: Associations With SARS-CoV-2 COVID-19 ACE2-TMPRSS2-Furin-DPP4 Axis RESULTS: Several genes were differentially expressed in younger and older smokers, and patients with COPD and IPF compared to non-smokers which were part of the mitochondrial biogenesis/function (HSPD1, FEN1, COX18, COX10, UCP2 & 3), cellular senescence (PCNA, PTEN, KLOTHO, CDKN1C, TNKS2, NFATC1 & 2, GADD45A), and telomere replication/maintenance (PARP1, SIRT6, NBN, TERT, RAD17, SLX4, HAT1) target genes. CONCLUSIONS: Overall, these findings suggest that altered transcription of target genes that regulate mitochondrial function, cellular senescence, and telomere attrition in the pathobiology of lung aging in COPD and IPF is associated with alterations in SARS-CoV-2 ACE2-TMPRSS2-Furin-DPP4 axis as pharmacological targets for COVID-19.
cord-311029-x0lk4110	2020	For that reason, the Clinical Trials Regulation (EC) No. 536/2014 states that "in order to improve treatments available for vulnerable groups such as frail or older people, people suffering from multiple chronic conditions, and people affected by mental health disorders, medicinal products which are likely to be of significant clinical value should be fully and appropriately studied for their effects in these specific groups, including as regards requirements related to their specific characteristics and the protection of the health and well-being of subjects belonging to these groups." Indeed, EMA develops scientific guidelines to help medicine developers address the specific requirements of older people in their medicine development programs, including in the design and conduct of clinical trials. EMA disclosed a reflection paper on "Physical frailty: instruments for baseline characterization of older populations in clinical trials" (7), actively recognizing the importance of considering the various types of aging when experimenting and developing new pharmacological treatments.
cord-312840-jvdph782	2014	We introduce a simple method to estimate the reproductive number by modifying the method originally proposed by Wallinga and Teunis and using existing information on contact patterns between age groups. Studies examining disease transmission by age have consistently shown that children have higher estimated values of the reproductive number than adults. Figures 3a and 3b shows the estimates of R 0 across the 10 age groups obtained when using contact patterns from South Africa and the eight European countries in the PolyMod study for all close contacts (Figure 3a ) and all contacts involving physical touch (Figure 3b ). We present a novel approach to estimating the effective and basic reproductive number by age group, and have applied this method to data from the 2009 Influenza H1N1pdm in Gauteng Province in South Africa. We have applied a novel method to estimate transmission patterns between individuals from different age groups during the 2009 Influenza H1N1pdm in South Africa.

Comparing the 2011 and 2016 censuses, the ratio of people aged 65 and older living in "collective dwellings" (e.g., assisted living, supportive housing, retirement residences, seniors'' apartments, continuum care facilities, and nursing homes) has dropped from 7.9% to 6.9% (Garner, Tanuseputro, Manuel, & Sanmartin, 2018; Statistics Canada, 2012) . For example, in a public guide issued by the federal government, "aging in place" is defined as "having access to services and the health and social supports and services you need to live safely and independently in your home or your community for as long as you wish and are able" (Federal/Provincial/Territorial Ministers Responsible for Seniors, 2015, p.1).
cord-315126-713k0b9u	2020	Second, with these debunked myths as a backdrop, we focus on two alternative and complementary frameworks—the social constructionist perspective and the lifespan development perspective—with promise for changing the way we think about age, aging, and generations at work. We argue that the social constructionist perspective offers important opportunities for understanding the persistence and pervasiveness of generations and that, as an alternative to studying generations, the lifespan perspective represents a better model for understanding how age operates and development unfolds at work. These complementary approaches-the social constructionist and the lifespan development perspective-offer alternative paths forward for studying age and age-related processes at work that do not require a reliance on generational explanations. The social constructionist perspective also encourages changing the discourse among practitioners, shifting the focus away from managing generations as discrete groups and toward developing more age-conscious personnel practices, policies, and procedures that support workers across the entirety of their working lifespans (e.g., Rudolph & Zacher, 2020c) .
cord-315992-jxxio17w	2020	The role of microRNAs (miRNAs, miRs) as epigenetic modifiers in regulating loss of muscle mass and function has become increasingly recognised (reviewed in [17] ). It therefore appears that miR-181 may play a critical role in regulating redox homeostasis and potentially mitochondrial dynamics in nervous and cardiac cells, with studies suggesting that inhibition of miR-181 may prevent cell death and improve antioxidant response via targeting BCL-1, BCL-2, GRP78 and PTEN. In our study, using miR gain-and loss-of-function approaches, we have demonstrated that miR-181 regulates skeletal muscle size and function during aging through regulating mitochondrial dynamics [46] . This may also suggest the important role of miR-181 family in a multitude of disorders associated with changes in mitochondrial dynamics and oxidative stress, such as sarcopenia or aging. The potential of miRs as novel therapeutics for various disorders has been proposed due to their implication in regulating multiple pathways and involvement in many disease states including aging and sarcopenia [25] , [27] , [35] .
cord-317519-yhzv2yjs	2020	Development and use of drugs like rapamycin and metformin by the at-risk population, notably older adults, may confer broad health benefits by targeting multiple aspects of biological aging and in this way raise the chances that these people can ward off the worst effects of COVID-19. Randomized, controlled clinical trials to assess the ability of rapamycin, metformin and other potential geroprotective drugs [20] , to boost response to an eventual COVID-19 vaccine in the elderly, as well as protect against COVID-19 infection altogether, could have a substantial impact on survival in vulnerable populations and should be pursued. Often, in older patients, multiple aging-related diseases are affected by multiple risk factors, further increasing the disability and mortality. The COVID-19 global emergency has emphasized to vast masses of people the vital need to prevent old-age multimorbidity, protect the elderly and improve their health span.
cord-317583-jhulvfev	2020	Blanchflower and Oswald (2008a) find a U-shape for 39 developing countries in World Values Survey sweeps 1-4 4 that averages out at a minimum around age 43 when including control variables. I then turn to examining data for the UK and 36 European countries and find there is evidence of a U-shape whether controls are included or not, with very little difference in the age minima. Blanchflower and Graham examined the same data Ingelhardt used and estimated a series of happiness equations and found there were U-shapes in age with controls in all the countries and variables Ingelhardt examined. Fourteen of those countries have significant and well-defined U-shapes in age and they are not available in any of the other data files, so in Table 14 we report results for these developing countries using the Q1 question above for Cantril''s life satisfaction ladder measure.
cord-318977-4ng6gxpv	2020	To develop such a theoretical frame, we draw on a sociocultural psychology of learning and development, which so far has been mainly focused on children, young adults and adults, as well as on the growing field of anthropological (Droz-Mendelzweig, 2013; Lieblich, 2014; Sarason, 2011) , critical gerontology, sociological and narrative approaches (Freeman, 2011; Gubrium, 1995 Gubrium, , 2011 , and clinical studies of the lives of older people (Aumont & Coconnier, 2016; Bergeret-Amselek, 2016; Gutton, 2016; Quinodoz, 2008; Villa, 2010) . Sociocultural psychology is a theoretical approach to human experience and development that considers the mutual constitution of the person and their social and cultural world, as these dynamics are located in time and space; it also gives a central role to human experience and sense-making (Cole, 1996; Rosa & Valsiner, 2018; Valsiner, 2012; Wertsch, 1998) . Hence, at a sociogenetic level, we call for a careful analysis of the historical evolution and local specificities of the dominant discourses on ageing persons, the institutional arrangements setting conditions for older people''s lives, and the differentiated dynamics of social inclusion and exclusion of elderly persons.
cord-322024-yrqpq9cf	2013	METHODS: Stool samples and nasopharyngeal (NP) swabs collected from 260 children hospitalized for AGE (160 also had respiratory symptoms) and 157 otherwise healthy control children admitted for elective surgery were tested for the presence of four HCoVs using real time RT-PCR. CONCLUSIONS: Although HCoVs were more frequently detected in patients with AGE than in the control group, high prevalence of HCoVs in NP swabs compounded by their low occurrence in stool samples and detection of other viruses in stool samples, indicate that HCoVs probably play only a minor role in causing gastrointestinal illness in children <6 years old. The main objective of the present study was to evaluate the presence of HCoVs in simultaneously collected stool samples and nasopharyngeal (NP) swabs in children with AGE (with or without associated respiratory symptoms) and in control subjects, with the aim of appraising their role in the etiology of AGE.
cord-322486-qwl7nzkr	2020	We estimated the parameter which describes the age-dependency of susceptibility by fitting the model to reported data, including the effect of change in contact patterns during the epidemics of COVID-19, and the fraction of symptomatic infections. Our study revealed that if the mortality rate or the fraction of symptomatic infections among all COVID-19 cases does not depend on age, then unrealistically different age-dependencies of susceptibilities against COVID-19 infections between Italy, Japan, and Spain are required to explain the similar age distribution of mortality but different basic reproduction numbers (R(0)). Assuming that the age-dependency of mortality by COVID-19 is determined by only age-dependent susceptibility (model 1), i.e., the mortality rate does not depend on age, the exponent parameter, φ, describing the variation of susceptibility among age groups for each country, Italy, Japan, and Spain, was estimated as shown in Fig. 4 .
cord-322704-0suc6pt6	2020	COVerAGE-DB is an open access database including cumulative counts of confirmed COVID-19 cases, deaths, and tests by age and sex. Centralization, standardization, and harmonization of data is critical to enable comparisons of the demographic impact of COVID-19 vis-à-vis differences in the age-compositions of confirmed infections and deaths. At this writing, the database contai ns daily counts of COVID-19 cases, deaths, and tests performed by age and sex for 87 national and 195 subnational populations around the world, depending on the available data for each source. Generally, COVID-19 cases, deaths and tests are reported as counts in 10-year age groups, but some sources report data in other metrics (fractions, percents, ratios) or as summary indicators such as case fatality ratios by age. The main strength of COVerAGE-DB is to provide a centralized, open-access, and fully reproducible repository of age-and sex-specific case, death, and test counts from COVID-19, collected from official sources, and harmonized to standard output formats.

The complex and still unclear immunopathological mechanisms of SARS-CoV-2 infection, together with the progressive age-related decline of innate and adaptive immune responses, and the lack of a clear correlate of protection, make the design of vaccination strategies for older people extremely challenging (Fig. 3 ).

cord-323582-7y8pt72r	2020	We developed a model that employed supervised machine learning algorithms to identify the presentation features predicting COVID-19 disease diagnoses with high accuracy. We implemented and applied several machine learning algorithms to our collected data and found that the XGBoost algorithm performed with the highest accuracy (>85%) to predict and select features that correctly indicate COVID-19 status for all age groups. We extracted important features of basic information (age, gender), symptoms (fever, cough, muscle soreness), diagnostic results (lung infection, radiographic imaging), prior disease/symptom history (pneumonia, diarrhea, runny nose) and some trajectory information (isolation treatment status, travel history) that are directly or indirectly related to COVID-19 disease. In our study, we developed and tested a range of machine learning approaches and found the most significant clinical COVID-19 predictive features were (in descending order): lung infection, cough, pneumonia, runny nose, travel history, fever, isolation, age, muscle soreness, diarrhea, and gender.

The first data on infection in nursing homes in Spain come from the EPINGER study, conducted in community health centres in Catalonia, which reported a prevalence of 6.5%, although it should be pointed out that in Catalonia the concept of the community health centre would include medium-long term patients, while in the rest of the Spanish autonomous communities this concept would be limited to nursing homes [40] . This is a multi-centre system for monitoring nosocomial infections, based on the production of an annual prevalence study, which has been conducted since 1990 in a large group of hospitals in Spain and was promoted by the Spanish Society of Preventive Medicine, Public Health and Hygiene. The studies reviewed allow us to estimate a prevalence of infection of between 4 and 10% in nursing homes in Spain, depending on their complexity, and between 6 and 9% in hospitalised elderly people.
cord-325722-ixozph19	2020	The results indicate that by tailoring measures to specific subgroups, the overall number of CSSA recipients would be reduced, thereby improving the efficiency of Hong Kong''s social security system, which has accounted for more than 16.5% of Hong Kong government expenditure in 2018, amounting to more than HKD 92 billion. It is important to consider whether the "entering approach" is indeed more effective than the "leaving approach" in reducing the number of CSSA recipients in Hong Kong. From these results, it seems that preventing people aged 20-29 from entering the CSSA system has a larger impact; that is, the "entering" approach would be more effective in reducing the number of CSSA recipients in 2014. The propose model provides empirical evidence to identify the potential target groups of people that would lead to the largest reduction in the number of the CSSA recipients in the Hong Kong Social Security System.
cord-329626-lsbny5to	2020	Being female, younger, having negative self-perceptions about aging, more time exposed to news about COVID-19, more contact with relatives different to those that co-reside, fewer positive emotions, less perceived self-efficacy, lower quality of sleep, higher expressed emotion and higher loneliness were associated with higher distress. Drawing upon the stress and coping model (Lazarus & Folkman, 1984) , which highlights the relevance of personal or social resources for understanding the differences in distress between individuals, the objective of this study is to analyze the capacity of variables related to the outbreak of COVID-19 to explain loneliness and distress in people exposed to COVID-19 lock-down scenario, controlling for sociodemographic variables (including age and selfperceptions of aging), and personal and family resources. The variables with a significant contribution to explaining distress in the final model were: being female, of lower chronological age, higher negative self-perceptions about aging, more time devoted to COVID-19 information, more contact with other relatives different to those that co-reside, fewer daily positive emotions, less perceived self-efficacy, lower reported quality of sleep, higher expressed emotion and higher loneliness.
cord-331065-tzvkj2rm	2020	The only significant predictor of change in subjective age was the belief that the "coronavirus is only a threat to older adults": The more individuals agreed with this statement, the more likely it was that they felt increasingly younger at follow-up. Experimental research found that when individuals are exposed to negative age-related information, they react by distancing themselves from their age-group and their chronological age, resulting in a younger subjective age (Weiss & Freund, 2012; Weiss & Lang, 2012 The primary scope of the study was to examine the trajectory of subjective age in the context of COVID-19 with longitudinal data from a nation-wide sample of Americans aged 18 to 100 years. We tested the five moderators (age, disease burden, negative expectations about aging, "coronavirus is only a threat to older adults", and stress) in one model that included data from the first two waves, the A c c e p t e d M a n u s c r i p t 14 demographic covariates, and the main effects and interactions with time of the six variables.
cord-335635-41u0cq1h	2020	However, because of the lack of open and multi-ethnic datasets, most modern age and gender estimating models were trained solely based on white people with Western facial features, and thus fall short with non-Caucasian people. In this paper, we developed an applicable Wide ResNet model to estimate the age and the gender of Asian faces. Ultimately, the final aim of my paper is to make the best use of the data, as well as the existing deep learning techniques to put together a wellrounded implementation of Wide ResNet to create a reliable program that can be able to extract the age and gender of a certain Asian person with reasonable accuracy on both aspects. Most modern Age and Gender estimating models were trained based on white people with Western facial features, and the application on Asian faces has limitations.
cord-340028-6oicmeam	2020	Here we compare the expected benefit of treatments for elderly populations (60 years and older) that are currently in development, including standard preventative strategies such as vaccines and antivirals targeting SARS-CoV-2, and the potential added benefit of speculative geroprotective strategies such as rapalogs, NAD+ boosters, senolytics, and stem cell treatment. People >60 years of age with chronic medical conditions, such as type 2 diabetes or cardiovascular disease, direct immunosuppression from HIV, posttransplant or biologic treatment, pregnant individuals, or those with BMI>40, are believed to be at higher risk for influenza infection due to a weakened immune response [31] . As discussed in this paper, small clinical studies have shown that several geroprotective and senoremediative interventions, such as treatment with AGING sirolimus and rapalogs, can induce immunopotentiation, increase resistance to infection, and reduce disease severity in the elderly, without severe side effects.
cord-340285-mq9x12nw	2020	In contrast, as we will discuss in the next section, it is hyper-functional immune response that leads to death from COVID-19 in the elderly by causing cytokine storm. It is driven by nutrient/hormone/cytokinesensing and growth-promoting signaling pathways such as Target of Rapamycin (TOR; mTOR), which are involved in developmental growth and later cause hyperfunctional aging and its diseases [24, 26] . Nutrients and obesity activate growth-promoting pathways (e.g., mTOR), thus accelerating development of quasi-programmed (age-related) diseases. Continuous use of rapamycin is expected to improve health, decrease age-related diseases and extend healthy lifespan, rendering individuals less vulnerable, when infected with the virus. As we discussed in the section "Cytokine storm is a hyperfunction", cytokine storm and hyper-inflammation is a main cause of death in COVID-19 pneumonia [36-40, 42, 45, 135, 141-143] Rapamycin, an antiinflammatory agent, inhibits hyper-functions, cellular senescence and decrease secretion of cytokines ( [74, 81, 144] .
cord-344653-to7571tw	2020	In the current studies, we examined mood, expectations regarding aging, coronavirus attitudes, and loneliness in younger and older adults. Eighty-six older adults who completed the Expectations Regarding Aging (ERA) and Brief Mood Introspection Scale (BMIS) between January 2018 and December 2019 (Time 1) were contacted to participate. In Study 1, we found that overall, our sample of older adults was maintaining positive mood and expectations about aging during the COVID-19 pandemic, but that they reported more negative arousal. In Study 2, we attempted to replicate findings from Study 1 regarding loneliness, COVID-19 attitudes, mood, and expectations regarding aging in a larger sample of older adults. We also examined age-related differences in mood, expectations about aging, loneliness, and attitudes toward COVID-19 in a national sample of older and younger adults. Pearson''s correlations were conducted within each age group to examine associations between overall ERA score, BMIS pleasant-unpleasant mood, COVID-19 score, loneliness rating, and relevant demographic factors like age, gender, education, income, and overall health.

To test whether the epidemic influenced the educational attainment of exposed cohorts, we match a sample of white males born between 1895 and 1916 with the 1916 polio morbidity rate in their state of birth, and the years of education they report having in the 1940 US Census (Ruggles et al. 25 Results reported in Table 7 show that including the influenza death rate and its interactions with age groups does not affect our finding that children of legal working age in states with greater numbers of polio cases had less educational attainment.
cord-352620-a0tt0ldm	2016	However, aged wolves'' life spans far exceeded those of similar‐sized domestic dogs and breeds, suggesting the possibility of an important species difference that should be explored. By comparison, many studies of shoulder diseases of domestic dogs have focused on imaging modalities, osteochondroses (Olsson, 1982) , and a variety of congenital or acquired problems involving tendon, ligament, muscle, joint capsule, and nerve structures that surround the joint (Sumner-Smith, 1993) . The comparative observation raises the question of whether an "aging threshold" exists in the gray wolf, as lifetime data appear to suggest for the domestic dog . Thus, the accumulated data suggest that cartilage degradation and its associated progressive histological inflammatory process are responsible for the aligned articular bone features that we observed in the gray wolves. When interpreting archaeological canid dry bone specimens, it is useful to retain this mental view of the overall process of degenerative joint disease, as observed in the domestic dog.
cord-352737-3ttrx3lf	2020	Enhancing the efficacy of the adaptive immune response may be an important issue both for infection resolution as well as for the appropriate generation of immunity upon vaccination, while inhibiting inflamm-aging will likely emerge as a potential complementary therapeutic approach in the management of patients with severe COVID-19. Enhancing the efficacy of the adaptive immune response may be an important issue both for infection resolution as well as for the appropriate generation of immunity upon vaccination, while inhibiting inflamm-aging will likely emerge as a potential complementary therapeutic approach in the management of patients with severe COVID-19. Interestingly, polymorphonuclear leucocytes from the elderly are less capable of modulating the triggering receptor expressed on myeloid cell-1 (TREM-1)-induced oxidative bursts, suggesting that TREM-1 signal transduction altered with aging may be one of the mediators of the decrease in microbicidal potential of innate immune cells in older adults (41) .
cord-353600-5wo74ms4	2020	In mice, ageing is associated with an elevation in the levels of the inflammatory cytokine IL-6 in the aorta, which participates in a positive feedback loop with the impaired vascular mitochondrial function to accelerate atherogenesis. • Ageing-related alterations in the bone marrow increase the phenomenon of clonal haematopoiesis of indeterminate potential (CHIP) and promote a skewing towards myeloid cell differentiation, both of which can accelerate atherosclerosis. • The role of the vasculature and myeloid cells of the immune system in promoting age-related atherosclerosis might be mediated by shared inflammatory pathways, in particular IL-6 signalling. In a 2019 study in mice, β 2 adrenergic receptor signalling in the bone marrow niche was found to increase with ageing in association with increased generation of myeloid cells and platelets through an IL6 dependent mechanism 60 . Blocking IL-6 might interfere with the increased IL-6 signalling in bone marrow adipocytes that occurs with ageing (which promotes a skewing towards myeloid cell differentiation), thereby reducing the risk of clonal haematopoiesis of indeterminate potential (CHIP).
