RESUMO

Super-agers are older adults with exemplary cognitive and/or physical abilities. However, the impact of media portrayals of super-agers is unknown. This study examined whether exposure to mass media stories about "moderate" super-agers (exemplary cognitive and physical skill levels) versus "extreme" super-agers (most extreme cognitive and physical skill levels) impacts young adults' ageism. Undergraduate participants exposed to media portrayals of moderate super-agers reported greater agreement with positive age stereotypes toward older adults, whereas participants exposed to extreme super-agers reported lower levels of ageism as compared to control participants. Based on these findings, young adults may perceive super-agers in a positive manner as super-agers highlight positive attributes. Since super-agers are often portrayed as defying negative stereotypes through diligence and a positive outlook (less so through good genes or access to healthcare), exposure to super-agers could have negative effects, which is an important future direction.

RESUMO

OBJECTIVES: During the coronavirus disease 2019 (COVID-19) pandemic, older adults have been disproportionately affected by high rates of health complications and mortality. Reactions toward older adults included a mix of prosocial behaviors and ageist responses, consistent with the history of positive and negative views and treatment of older adults in the United States. METHODS: In a two-part study (n = 113, Mage = 18.49, SD = 0.50; range 18-19), we examined whether pre-pandemic ageism among undergraduates predicts prosocial behavioral intentions toward older adults both specific to COVID-19 and in general. RESULTS: Pre-pandemic ageism toward older adults predicted less intentions to help older adults generally and specific to COVID-19. Whereas viewing older adults as incompetent predicted greater intentions to help specific to COVID-19. DISCUSSION: These results reflect the complexity of predicting helping behaviors and suggest that even supportive behaviors toward older adults during the COVID-19 pandemic may be rooted in negative ageist stereotypes. Implications and directions for future research are discussed.

RESUMO

The COVID-19 pandemic is a significant global issue that has exacerbated pre-existing structural and social inequalities. There are concerns that ageism toward older adults has intensified in conjunction with elevated forms of other "isms" such as ableism, classism, heterosexism, racism, and sexism. This study offers a systematic review (PRISMA) of ageism toward older adults interacting with other isms during the COVID-19 pandemic. Articles were searched in 10 databases resulting in 354 ageism studies published between 2019 and August 2022 in English, French, Portuguese, or Spanish. Only 32 articles met eligibility criteria (ageism together with other ism(s); focus on the COVID-19 pandemic); which were mostly review papers (n = 25) with few empirical papers (n = 7), reflecting almost all qualitative designs (n = 6). Articles discussed ageism with racism (n = 15), classism (n = 11), ableism (n = 9), sexism (n = 7), and heterosexism (n = 2). Authors represented numerous disciplines (gerontology, medicine, nursing, psychology, social work, and sociology) and countries (n = 14) from several continents. Results from this study underscore that ageism intersects with other isms in profoundly negative ways and that the intersections of ageism and other isms are understudied, requiring more research and intervention efforts.

RESUMO

BACKGROUND: Rapid spread of SARS-CoV-2 has led to a global pandemic, resulting in the need for rapid assays to allow diagnosis and prevention of transmission. Reverse transcription-polymerase chain reaction (RT-PCR) provides a gold standard assay for SARS-CoV-2 RNA, but instrument costs are high and supply chains are potentially fragile, motivating interest in additional assay methods. Reverse transcription and loop-mediated isothermal amplification (RT-LAMP) provides an alternative that uses orthogonal and often less expensive reagents without the need for thermocyclers. The presence of SARS-CoV-2 RNA is typically detected using dyes to report bulk amplification of DNA; however, a common artifact is nonspecific DNA amplification, which complicates detection. RESULTS: Here we describe the design and testing of molecular beacons, which allow sequence-specific detection of SARS-CoV-2 genomes with improved discrimination in simple reaction mixtures. To optimize beacons for RT-LAMP, multiple locked nucleic acid monomers were incorporated to elevate melting temperatures. We also show how beacons with different fluorescent labels can allow convenient multiplex detection of several amplicons in "single pot" reactions, including incorporation of a human RNA LAMP-BEAC assay to confirm sample integrity. Comparison of LAMP-BEAC and RT-qPCR on clinical saliva samples showed good concordance between assays. To facilitate implementation, we developed custom polymerases for LAMP-BEAC and inexpensive purification procedures, which also facilitates increasing sensitivity by increasing reaction volumes. CONCLUSIONS: LAMP-BEAC thus provides an affordable and simple SARS-CoV-2 RNA assay suitable for population screening; implementation of the assay has allowed robust screening of thousands of saliva samples per week.

RESUMO

BACKGROUND AND OBJECTIVES: Benevolent and hostile ageism are subtypes of ageism that characterize older adults as incompetent. With benevolent ageism, older adults are also viewed as warm. The coronavirus disease 2019 (COVID-19) pandemic has strained resources and prompted debates about priority for older adults versus other groups. RESEARCH DESIGN AND METHODS: College students completed an online survey of how much priority should be given to older adults in 3 relevant health care-related scenarios and 3 relevant employment scenarios. RESULTS: Benevolent ageism significantly predicted higher priority for older adults to receive health care (triage, COVID-19 vaccine, and COVID-19 testing) and employment resources (retention of job and working from home) while greater endorsement of hostile ageism significantly predicted lower priority ratings. DISCUSSION AND IMPLICATIONS: These findings replicate and extend past work. As the COVID-19 pandemic continues to wreak havoc on health care and employment resources, this study sheds light on one factor-benevolent and hostile ageism-that contributes to a greater understanding of prioritization views toward a vulnerable segment of the population.

RESUMO

The disproportionately high rates of coronavirus disease 2019 (COVID-19) health complications and mortality among older adults prompted supportive public responses, such as special senior early shopping hours and penpal programs. Simultaneously, some older adults faced neglect and blatant displays of ageism (e.g., #BoomerRemover) and were considered the lowest priority to receive health care. This article examines positive and negative responses toward older adults in the United States during the pandemic and the consequences for older adults and society using data from the pandemic in the United States (and informed by data from other countries) as well as past theorizing and empirical research on views and treatment of older adults. Specifically, positive responses can reinforce the value of older adults, improve older adults' mental and physical health, reduce ageism, and improve intergenerational relations, whereas negative responses can have the opposite effects. However, positive responses (social distancing to protect older adults from COVID-19 infection) can inadvertently increase loneliness, depression, health problems, and negative stereotyping of older adults (e.g., helpless, weak). Pressing policy issues evident from the treatment of older adults during the pandemic include health care (triaging, elder abuse), employment (layoffs, retirement), and education about ageism, as well as the intersection of ageism with other forms of prejudice (e.g., racism) that cuts across these policies.

RESUMO

The proportion of US food that is imported is increasing; most seafood and half of fruits are imported. We identified a small but increasing number of foodborne disease outbreaks associated with imported foods, most commonly fish and produce. New outbreak investigation tools and federal regulatory authority are key to maintaining food safety.

RESUMO

Background. In September 2012, the Centers for Disease Control and Prevention (CDC), U.S. Food and Drug Administration (FDA), and state and local partners investigated an outbreak of Salmonella enterica serovar Bredeney linked to peanut butter (PB). Methods. A case was defined as infection with the outbreak strain of Salmonella Bredeney between June 1, 2012 and October 31, 2012. Food exposure questionnaires were analyzed by the CDC to determine the food vehicle. The FDA reviewed production information from Retail Chain A's sole supplier of PB, Company A. The PB samples collected from case-patients and Company A were tested for Salmonella. Results. Forty-two case-patients from 20 states were identified. Of 33 case-patients from whom food exposure information was obtained, 25 (76%) shopped at Retail Chain A and 25 (100%) purchased Company A PB. Three state health departments isolated the outbreak strain from opened jars of PB collected from case-patients. The FDA investigators identified multiple deficiencies in current Good Manufacturing Practices (cGMPs) in Company A's manufacturing facility and determined that internal controls were insufficient to prevent shipment of contaminated product. The FDA isolated the outbreak strain of Salmonella Bredeney from implicated product collected at the firm and the environment of the firm's food production facility. Conclusions. Timely laboratory, investigational, and epidemiologic data led to the voluntary recall of PB by Company A. The FDA suspended Company A's food facility registration, prohibiting the firm from introducing food into interstate commerce. This outbreak underscores the need for effective preventive controls, including robust internal environmental monitoring programs, appropriate action in response to contamination findings, and an improved understanding of food safety at the managerial and corporate levels.

RESUMO

OBJECTIVE: Liver disease is a potential complication from using dietary supplements. This study investigated an outbreak of non-viral liver disease associated with the use of OxyELITE Pro(TM), a dietary supplement used for weight loss and/or muscle building. METHODS: Illness details were ascertained from MedWatch reports submitted to the U.S. Food and Drug Administration (FDA) describing consumers who ingested OxyELITE Pro alone or in combination with other dietary supplements. FDA's Forensic Chemistry Center analyzed samples of OxyELITE Pro. RESULTS: From February 2012 to February 2014, FDA received 114 reports of adverse events of all kinds involving consumers who ingested OxyELITE Pro. The onset of illness for the first report was December 2010 and for the last report was January 2014. Thirty-three states, two foreign nations, and Puerto Rico submitted reports. Fifty-five of the reports (48%) described liver disease in the absence of viral infection, gallbladder disease, autoimmune disease, or other known causes of liver damage. A total of 33 (60%) of these patients were hospitalized, and three underwent liver transplantation. In early 2013, OxyELITE Pro products entered the market with a formulation distinct from products sold previously. The new formulation replaced 1,3-dimethylamylamine with aegeline. However, the manufacturer failed to submit to FDA a required "new dietary ingredient" notice for the use of aegeline in OxyELITE Pro products. Laboratory analysis identified no drugs, poisons, pharmaceuticals, toxic metals, usnic acid, N-Nitroso-fenfluramine, pyrrolizidine alkaloids, aristocholic acid, or phenethylamines in the products. CONCLUSIONS: Vigilant surveillance is required for adverse events linked to the use of dietary supplements.
