Newly emerged bumblebees are highly susceptible to gut parasite infection

AbstractOne factor that can affect infection susceptibility is host age, the effects of which vary in a range of ways. For example, susceptibility may increase with age, due to senescence or decrease with age as a result of maturation of the immune system. If certain ages are more susceptible to infection, populations with contrasting demographics, such as same-age cohorts versus a mixture of ages, will exhibit differing disease prevalence. We use the bumblebee, Bombus terrestris, and its interaction with the gut trypanosome Crithidia sp. as a model system to investigate age-related susceptibility in a social insect. Crithidia sp. are widespread and prevalent parasites of bumblebees that are spread between colonies via faeces on flowers when foraging, and within colonies via contact with infected bees and contaminated surfaces and resources. In the field, Bombus spp. live for approximately three weeks. Here, we inoculated bumblebees at 0, 7, 14 and 21 days of age and measured their infection after one week. We also measured the level of gene expression of two antimicrobial peptides important in the defence against Crithidia bombi in bumblebees. We found that younger bumblebees are more susceptible to infection by Crithidia sp. than their older siblings. Specifically, individuals inoculated on their first day of emergence had infection intensities seven days later that were four-fold higher than bees inoculated at 21 days of age. In contrast, the gene expression of two AMPs known to protect against the trypanosome, abaecin and defensin, did not significantly vary with age. These results suggest that age does affect susceptibility to Crithidia sp. infection in B. terrestris. The higher susceptibility of callows may have implications for the susceptibility of colonies at different stages of their lifecycle, due to the contrasting age demography of workers in the colony.

FIVE BIODEMOGRAPHIC PRINCIPLES OF AGING THAT EMERGED FROM RESEARCH ON THE MEDITERRANEAN FRUIT FLY

Abstract Because of its large size, visually-distinct sex differences, abundance in the wild and ease of rearing at both industrial and individual levels, the Mediterranean fruit fly (medfly) is an ideal model organism for conducting research on the demography of aging. I will present details on and implications for what I consider to be the five most interesting and important aging-related discoveries from the NIA-funded research my colleagues and I conducted over the past three decades using the medfly model. These discoveries include (1)Deceleration of mortality at advanced ages; (2)Equivocality of the gender gap due to context-specific sex mortality relationships; (3)Supine behavior as a biomarker of both morbidity onset and time-to-death; (4)A dietary disconnect between maximizing longevity vs maximizing lifetime reproduction; and (5)the life table population identity in which the fraction age x in a stationary population equals the fraction with x years to live. I will end with brief comments about the use of non-conventional model organisms for research on aging in both the laboratory and the field.

Demonstration of a contactless waste collection system: A Japanese case study

AbstractThe COVID‐19 pandemic has increased the need for social distancing and improved sanitation to prevent the spread of infectious diseases. In the waste management sector, protecting the safety and health of waste collection labourer has become a priority. In Japan, the labour shortage problem and ageing demography have intensified the need for contactless waste collection technology. This study responds to this need by reviewing the global practice of smart waste collection technologies and observing the situation of the Japanese waste collection system through participant observation. Based on the identified trends and status, the authors developed a contactless waste collection system and tested it on an actual working site. The demonstration showed that the system could safely lift a 700 L waste container containing 212 kg of waste to the collection truck without human contact. Labourers can be reduced from 2 to 1 person to operate the collection truck. This study also discovered the smart bin's potential to motivate the reduction of packaging waste consumption.

Painted in Broad Strokes: English-Language News Media Coverage of Home Care in Relation to the COVID-19 Pandemic in Canada

As eldercare was at the forefront of mainstream news media during the COVID-19 pandemic, these media accounts may draw on and/or further reshape public understandings of home care in Canada. A frame analysis informed by critical discourse theory was used to examine 56 English-language articles related to home care (March 2020–March 2021). Home care is often “tacked on” to discussions of long-term residential care and is constructed by what it is not, by what it is a preferred alternative to, and by what it might circumvent (i.e., neglect, contagion). Infused with taken-for-granted meanings and linked to population aging and system crisis, home care is positioned as the progressive future of Canadian eldercare. Although home care investment is a common call, at times the gravity of the problem is imbalanced against small-scale individualistic solutions. Inequities of home spaces and impacts on families are obscured, with homes characterized as idealized places of dignity and (relative) safety. Older adults are positioned as vulnerable, passive victims, in contrast to their benevolent helpers. The authors discuss how we can clarify and strengthen political advocacy and public discourse around eldercare without reinforcing compassionate ageism, apocalyptic demography, and fear of aging while recognizing the nuances around receiving care in either home or residential settings.

An Agricultural Career through the Lens of Young People

The lack of young people engaged in agriculture threatens future food security and social balance. The agricultural sector and rural areas are experiencing an aging demography. The data confirm the global historical trend of a shortage of young people deciding to pursue careers in agriculture and remaining in rural spaces. Understanding young people’s views on agriculture is the key to supporting their participation in the sector by examining the unattractive factors that influence their perceptions. This study aims to explore these factors through a literature review of the past 10 years, applying the PRISMA model. We used VOSviewer to identify the key elements linked in a co-word map and revealed four clusters that mainly influence young people’s perceptions. The reviewed papers are from developed and developing countries, as our approach seeks to transcend the national boundaries that often delimit analyses on generational renewal. The study brings out the common factors that affect youth’s choice in agriculture, highlighting their perceptions and aspirations. The discussions and conclusion aim to provide a different perspective to understand the decision-making process of young people toward an agricultural career.

A preliminary approach to Early Iron Age demography. Testing paleodemographic methodologies on a microspatial scale: The case of Punta de Muros (NW Iberia)

This paper presents an approach to the paleodemography of the Iron Age in the northwest of the Iberian Peninsula, choosing a microspatial study focused on the settlement of Punta de Muros. This settlement provides an excellent context for paleodemographic analysis, given the extent of its archaeological record, the chronological studies of its occupational dynamics and its condition as a fully excavated settlement. This work aims to review several demographic techniques in order to assess their weaknesses and strengths and their applicability to the case of study. Thus, the data obtained will be analysed from the point of view of their appropriateness and precision for Early Iron Age societies of the northwest, relating the results by means of several demographic markers and the archaeological data known for the settlement.

Norms of soft tissue cephalometric in the 18-25 age demography in Vietnam.

The soft-tissue layer and facial skeleton influence the harmony and equilibrium of the face. The evaluation of the patient's structural and soft-tissue features is one of the most crucial steps in preparing for the diagnosis and treatment of oral-maxillofacial orthodontics. Clinicians can intervene with the proper treatment at the proper time to achieve the best results by being aware of the traits and variations of soft tissue at various developmental stages and in various races. To obtain a consistent treatment result in terms of function and aesthetically pleasing results, patients, and forecast, the growth that may take place after the orthopedic therapy has concluded. To examine the soft-tissue features of the oral-maxillofacial area in Vietnamese adults (aged 18-25 years) by evaluating cephalometric radiographs. In a cross-sectional descriptive study, 85 students from Can Tho University of Medicine and Pharmacy took part. Students' lateral cephalograms were taken in compliance with the sample requirements. Men's lip protrusion (4.30 ± 0.71) was higher than women's (3.88 ± 0.97) (P = 0.024 <.05) and men's (-4.88 ± 0.93) chin lip groove depth was higher than women's (-4.24 ± 0.93) (P = 0.002), both with a P value of. 05. The study identified a statistically significant difference in the protrusion of the top lip and the depth of the cleft lip between the male and female, demonstrating that the soft-tissue features of Vietnamese students were distinct from those of other races.

FOSTERING MULTIDISCIPLINARY SOLUTIONS IN AGING: THE RESEARCH CENTERS COLLABORATIVE NETWORK

Abstract The NIA supports the Research Centers Collaborative Network (RCCN) to build collaborations between scientists from the 6 NIA-sponsored center programs: Alzheimer's Disease Research Centers, Centers on the Demography and Economics of Aging, Claude D. Pepper Older Americans Independence Centers, Nathan Shock Centers of Excellence in the Basic Biology of Aging, Resource Centers for Minority Aging Research, and Roybal Centers for Translational Research on Aging. RCCN's premise is that researchers from different disciplines are most likely to collaborate when they are addressing common problems. To provide a forum for collaborative exchange, the RCCN has convened 6 workshops on topics that cross-cut the concerns of the various NIA center programs ranging from sustaining behavior change in older adults to measuring biologic age. After each Workshop the RCCN awards pilot funds related to the theme. This symposium will present key learnings from the workshops and present work of four RCCN pilot teams from the third and fourth workshops which focused on resilience and reserve, and life course perspectives on aging. Dr. Ramos will discuss how measurement of psychological resilience may predict physical resilience in older patients with lung cancer, while Dr. Reid will discuss positive affect as a source of resilience for older adults with chronic pain. Dr. White will discuss association between perceived discrimination trajectories and multimorbidity burden among middle-aged and older black adults, while Dr. Brooks will discuss development of a resilience index in chronic musculoskeletal pain. Dr. Kritchevsky will also summarize lessons learned across the first 6 workshops.

Long-term outcomes of kidney transplantation from expanded criteria donors with Chinese novel donation policy: donation after citizens’ death

IntroductionThe Chinese Government initiated the Donation after Citizens' Death policy in 2010. To now, it has been a major source of organs for transplant. Since it is still a young policy, corresponding clinical evidence is still urgently needed for its improvement. Compared to kidneys donated by SCD (standard criteria donor), increasing the use of ECD (expanded criteria donor) derived kidneys is a way to expand the donor pool but is also a result of the aging demography of China. This study is based on the data of kidney transplantation in our center with the Donation after Citizens' Death policy, aiming to provide a reference for the clinical use of ECD kidneys.MethodA retrospective study enrolled 415 kidney transplants derived from 211 donors performed between October 2011 and October 2019. A total of 311 (74.9%) organs were donated from 159 (75.4%) SCDs, and the remaining 104 (25.1%) were from 52 (24.6%) ECDs. The log-rank test was used to compare the difference in survival and postoperative complications. The Chi-square test was used to compare the occurrence of postoperative complications and postoperative renal function. The Cox regression analysis was used for risk factor screening.ResultAnalysis showed that grafts from ECD were poorer in survival (P = 0.013), while their recipients had comparable (P = 0.16) survival. Moreover, it also was an independent risk factor for graft loss (HR 2.27, P = 0.044). There were significantly more AR occurrences in the ECD group compared with SCD group (25.0% vs. 15.8%, P = 0.004), but no significant difference was found in infection (51.9% vs. 47.6%, P = 0.497) and DGF (26.0% vs. 21.9%, P = 0.419) between them. Similarly, fewer recipients in the ECD group were free from AR within 1 year after transplantation (P = 0.040), with no statistical difference in all-cause infection prevalence in 1 year (P = 0.168). The eGFR in the ECD group was significantly worse than that in the SCD group at 3 months, 6 months, 1 year, 3 years, and the highest value posttransplant (all < 0.05), but no difference at 5 years posttransplant. Besides, results showed cardiac arrest (uncontrolled vs. controlled, HR 2.49, P = 0.049), HLA mismatch (4–6 loci vs. 0–3 loci, HR 3.61, P = 0.039), and AR occurrence (HR 2.91, P = 0.006) were demonstrated to be independent risk factors for graft loss.ConclusionThe ECD-derived kidney was worse than the SCD-derived kidney in terms of graft survival and AR occurrence, and trend to an inferior renal function postoperative. However, the recipient survival, DGF occurrence, and all-cause infection occurrence were similar.

Effect of lifestyle on the quality of life and general health of the elderly in Ahvaz, Iran

Background and Objectives: The study of the demography of aging in developing countries is a relatively new endeavor. This study aims to determine the effect of lifestyle on the quality of life and general health of the elderly in Ahvaz, Iran. Methods: This descriptive survey study was conducted on 1000 older adults aged &gt; 60 years in Ahvaz city in 2020. Data collection tools were a demographic form, the lifestyle questionnaire, the older people’s quality of life questionnaire, and the general health questionnaire. Data were analyzed using descriptive statistics (mean, frequency, and percentage) and inferential statistics (Pearson correlation test or Spearman correlation test). The significance level was set at 0.05. To test the conceptual model of the study, Structural Equation Modeling (SEM) was used in AMOS software. Results: All t coefficients for the factorial structure of the study model were greater than 1.96 and, thus, all study hypotheses were confirmed. The results showed that the lifestyle of the elderly had a significant effect on their general health. Conclusion: It is necessary to increase the knowledge of healthy lifestyle in the elderly living in Ahvaz city by using educational programs such as stress management training, healthy nutrition education, and recreational and sports programs.

Aging in Nigeria: A Growing Population of Older Adults Requires the Implementation of National Aging Policies.

While the continent of Africa currently has the lowest share of adults aged 60 and older in its population among all world regions, the total number of older Africans is projected to triple between 2020 and 2050. Nigeria-Africa's leading economy and most populated country-has the highest number of older people in the continent and the 19th highest across the globe, with the population of Nigerians aged 65 and older projected to nearly triple by 2050. However, the increase in older Nigerians is occurring against the backdrop of extreme poverty, unsolved development problems, socioeconomic inequality, the HIV/AIDS epidemic, and a decline in the traditional care and support of older adults. Additionally, the absence of an operational national aging policy or safety net services and programs poses a unique challenge to older Nigerians and their families. In this article, we examined social statistics and the current literature to describe aging in the Nigerian context. Our findings highlight the importance of establishing effective governmental policy interventions for the adequate care and support of older Nigerians and the training of gerontological professionals. This article will describe the demography of aging in Nigeria, significant areas of research, key scholars and publicly available data sets, public policy issues, and emerging issues affecting the health and well-being of older Nigerians.

Life and Death of Termite Colonies, a Decades-Long Age Demography Perspective

A eusocial insect colony represents a complex biological entity that must ensure degrees of perennity once it reaches maturity (production of dispersing imagoes over many successive years) to optimize its reproductive success. It is known that a subterranean termite colony invests differentially in different castes over time and adjusts colony functions depending on colony internal and external conditions over many years of activity. However, the current study demonstrates that Coptotermes formosanus Shiraki field mature colonies go through dramatic demographic changes and breeding structure shifts, even many years after they have reached reproductive success. By analyzing the changes in age demography of C. formosanus colonies from four field sites, we here provide a new perspective on how a colony may function over decades, which reveals that each colony demographic trajectory is unique. In a way, throughout its life, a termite colony displays its own “demographic individuality” that drives its growth, its foraging ability, its competitiveness, its age demography, its senescence and ultimately its death. This study is therefore a narrated story of the life -and death- of different C. formosanus field colonies over decades of observation.

Leveraging Free Public Use Data for Aging and Life Course Research

This symposium will showcase life course and aging research that is possible using freely available integrated census and survey data available via IPUMS. This session is organized by the Network for Data-Intensive Research on Aging (NDIRA) initiative at the University of Minnesota’s Life Course Center. NDIRA seeks to build and support an interdisciplinary community of scientists leveraging powerful data resources in innovative ways to understand health outcomes at older ages, as well as the demography and economics of aging. The session features papers that illustrate how to examine aging-related topics including health at older ages, work and socioeconomic conditions, and living conditions with a common thread of examining heterogeneity within groups. These papers all leverage freely available census and nationally-representative survey data, highlighting the potential value of these data for studying aging and the life course. By combining papers on an array of topics from a variety of data sources, this symposium highlights exemplar papers that demonstrate the types of novel research possible using public use census and survey data that NDIRA seeks to foster.

Education of values: Marketizing the aging population in urban China

In this article, I examine some of the marketing and sales strategies at Gardenview, a newly established eldercare company that ran a few residential eldercare facilities in Nanjing, China. There, like elsewhere in urban China, the projected aging demography was mobilized to push for an industrialization (chanyehua)—marketization and professionalization—of eldercare, transforming ideas and experience of eldercare by putting forward a new set of knowledge of aging. To this end, I first ground the rising eldercare industry in the transitioning paradigm of conceptualizing China’s population from population control to demographic aging. Then I explore ethnographically how Gardenview participated in the eldercare industry in a rapidly aging China. In particular, I look at the floorplans and the marketing stories as devices of the education of values—as prices, the good and desirable, and differentiators—to understand the social, economic, and ethical dynamics instigated by a transitioning demography. These values, as I show, are crucial in linking everyday life and choices with the paradigmatic shift of China’s population. Finally, I discuss how understanding the very processes of marketing and sales as an education of values could shed further light on what anthropologist Michael Fischer calls “literacies of the future” as a socially and economically elaborated and contested world of an aging China.

Socioeconomic status and tobacco consumption: Analyzing inequalities in China, Ghana, India, Mexico, the Russian Federation and South Africa

INTRODUCTIONGlobally, there has been a rapid rise in non-communicable diseases driven by changing lifestyle choices and health behaviors. Different lifestyle choices threaten to exacerbate existing health inequalities, yet evidence monitoring the extent of this impact in emerging economies is lacking. The article sets out to measure the level of wealth-related inequality and its drivers in one of these lifestyle choices, tobacco consumption, among populations aged ≥50 years in six Low- and Middle-Income Countries.METHODSThe study provides empirical evidence of the inequality in tobacco consumption across wealth groups in China, Ghana, India, Mexico, the Russian Federation and South Africa using the Erreygers’ corrected concentration indices. These inequalities are then decomposed to gain a deeper understanding of the factors and broader social forces driving inequality. The WHO SAGE data set, collected between 2008 and 2010, is used for the analysis.RESULTSCurrent tobacco consumption is concentrated among the poor in China, Ghana, India, and South Africa, and among the wealthy in the Russian Federation and Mexico. The inequalities widen when we focus solely on the male population. Although the results differ by country, the major drivers of inequality include wealth, locality, and gender.CONCLUSIONSThe focus on tobacco consumption in this age group is key to curbing rising healthcare costs and ensuring longevity. Policies aimed at reducing wealth-related inequalities should especially target high tobacco consumption rates among males, while simultaneously pre-empting and curbing rising rates among women.

Understanding survey data available for researchers working in ageing: the CEPAR Metadata Database on Ageing

Background For researchers working in gerontology or the demography of ageing, knowledge of and access to population-based data, which includes mature age respondents, is critical. The collection of metadata (information describing data) supports researchers in their search for relevant data.&#x0D; Aims This proof-of-concept project seeks to develop a metadata database including metadata on Australian sample surveys relevant to ageing over the period 2010–2018.&#x0D; Data and methods We used a five-stage approach to create the Centre for Excellence in Population Ageing Research (CEPAR) metadata database on ageing: 1) identification of in-scope survey datasets; 2) indexing the in-scope surveys; 3) scraping metadata from publicly available sources; 4) appending metadata to a master database; and 5) creation of a webtool to enable users to search and export metadata and obtain contact details for the relevant data custodian.&#x0D; Results The CEPAR Metadata Database webtool is available from: https://mspgh.unimelb.edu.au/centres-institutes/centre-for-health-policy/research-group/metadata-database.&#x0D; Conclusions Metadata database collections can assist researchers to identify what data has been collected (for their specific research interest in ageing), how it was collected and how to gain access to the data.
