Social media promotion of harmful products (e.g., combustible tobacco) poses a public health threat. However, strategies that amplify exposure to and engagement with such content remain understudied. This study aims to characterize strategies boosting cigar, little cigar, and cigarillo (CLCC) marketing visibility, referrals, and engagement on Instagram. Using keyword rules, we collected publicly available CLCC-related Instagram posts from CrowdTangle for a six-year period from August 2016 to October 2021. Posts were categorized as commercial (e.g., posts by tobacco brands or vendors) or organic and were coded for consumer engagement (CE) strategies (e.g., presence of prompts to like/share) using a combination of machine learning methods and human coding. Temporal engagement trends were analyzed using metadata. A total of 320,488 CLCC-related public posts were collected, with 44.6% (n = 142,875) identified as overtly commercial. Of these, 33.5% (n = 47,832) contained CE cues, including discounts and giveaways for tagging peers, liking, commenting, or following CLCC brands and spokesperson/influencers accounts, as well as calls to participate in contests and polls. Overtly commercial CE messages consistently garnered more comments per post and likes per post than non-CE commercial posts. There was a significant upward trend in the rate of comments on CE posts, suggesting growing effectiveness in eliciting user interaction. The proliferation of and high level of engagement with cigar-related promotional messages on Instagram demonstrate the need for public health surveillance and regulation of the evolving strategies promoting CLCC marketing exposure, reach, and engagement on social media.

Background: Early language development, a key predictor of later academic achievement, arises out of social interactions and communication. High-quality social and emotional interactions in early child care and education (ECCE) programs may therefore promote language-rich environments for young children. While culturally and linguistically minoritized communities face systemic barriers that limit equitable access to high-quality ECCE including social and emotional learning (SEL) programs, access to evidence-based SEL programs remains inequitable, disproportionately benefiting White, English-speaking, and higher-income ECCE providers. The current study aims to examine how I-T CHILD, a program designed to foster a climate that supports mental health and SEL in ECCE, improves the quality of the language environment using LENA technology. Methods: Implemented at the height of the COVID-19 pandemic, 38 family child care providers located in an urban setting (63.2% Hispanic/Latine; 40% living in poverty) were randomly assigned to the 12-week I-T CHILD program or to the waitlist-control group. Data were analyzed using hierarchical linear modeling procedures. Results: Infants and toddlers cared for by I-T CHILD providers produced significantly more vocalizations (p = 0.002; ES = 1.50) and were exposed to significantly less media and electronic sounds (p = 0.032; ES = −0.97) than infants and toddlers in the waitlist-control condition. Conclusions: Our findings reinforce the importance of the mental health climate in ECCE and its circular effect on early language development. We offer key insights into how mental health climate interventions in ECCE settings can enhance language interactions, center the child, and foster foundational skills linked to long-term academic success for historically underserved populations.

Background: As global ageing accelerates, countries worldwide are increasingly facing social and economic challenges posed by rising older populations. Many nations are responding by optimizing healthcare systems, strengthening community-based ageing models, and promoting healthy ageing policies. The Naturally Occurring Retirement Community (NORC) is gaining recognition as a promising approach due to its cost efficiency and ability to meet diverse ageing-related needs. However, systematic research on the service models of NORCs remains scarce. Objective: This study aims to systematically examine the service offerings of Naturally Occurring Retirement Community Supportive Service Programs (NORC-SSPs) and analyze how these programs contribute to supporting ageing in place. Methods: A qualitative content analysis was conducted on official website information from 60 NORC-SSPs in New York State. Service categories were identified, coded, and compared across different geographic and structural contexts. Results: The analysis shows that education, healthcare management, and recreational activities are the most frequently provided services, with health-related services playing a central role in supporting older adults to age in place. Differences in service priorities were also observed between rural and non-rural settings, as well as between vertical and horizontal built environments, reflecting the adaptability of NORC-SSPs to varying community conditions. Conclusions: By identifying key service characteristics, this study provides insights for policymakers and practitioners in Australia and other countries seeking to implement sustainable, community-based models of ageing support. Grounded in the concept of “ageing in place”, the findings contribute to the development of inclusive and flexible service systems for older adults. Full article

Background/Objective: Platelet concentrates (PCs) are used in transfusion medicine to treat bleeding disorders. Staphylococcus aureus, a predominant PC contaminant, has been implicated in several adverse transfusion reactions. The aim of this study was to investigate the impact of PC storage on S. aureus resistance to quinolones, which are commonly used to treat S. aureus infections. Methods/Results: Four transfusion-relevant S. aureus strains (TRSs) were subjected to comparative transcriptome analyses when grown in PCs vs. trypticase soy broth (TSB). Results of these analyses revealed differentially expressed genes involved in antibiotic resistance. Of interest, the norB gene (encodes for the NorB efflux pump, which is implicated in quinolone resistance and is negatively regulated by MgrA) was upregulated (1.2–4.7-fold increase) in all PC-grown TRS compared to TSB cultures. Minimal Bactericidal Concentration (MBC) of ciprofloxacin and norfloxacin in PC-grown TRS compared to TSB showed increased resistance to both quinolones in PC cultures. Complementary studies with non-transfusion-relevant strains S. aureus RN6390 and its norB and mgrA deletion mutants were conducted. MBC of ciprofloxacin and norfloxacin and RT-qPCR assays of these strains showed that not only norB, but also norA and norC may be involved in enhanced quinolone resistance in PC-grown S. aureus. The role of norB in S. aureus virulence was also tested using the silkworm Bombyx mori animal model; lethal dose 50 (LD₅₀) assays revealed slightly higher virulence in larvae infected with the wild-type strain compared to the norB mutant. Conclusions: The PC storage environment enhances quinolone resistance in S. aureus and induces differential expression of efflux pump nor genes. Furthermore, our preliminary data of the involvement of NorB in virulence of S. aureus using a silkworm model merit further investigation with other systems such as a mammal animal model. Our results provide mechanistic insights to aid clinicians in the selection of antimicrobial treatment of patients receiving transfusions of S. aureus-contaminated PCs. Full article

Most older individuals prefer to age in place during their later years; however, achieving this aspiration presents significant challenges. Naturally Occurring Retirement Communities (NORCs) represent a potential option for promoting healthy aging, both from the perspective of meeting seniors’ real needs and cost-effectiveness. This article aims to analyze the distribution of NORCs in Australia and compares census data from 2011 to 2021 to understand the overall distribution patterns and changes across the nation, by providing a localized analysis of the hotspot distribution of NORCs in eight Greater Capital Cities. The study employs methods of geovisualization, Global Moran’s I, and Getis-Ord Gi* analysis to examine the spatial correlations and clustering effects of NORCs. The results indicate that NORCs are rapidly growing in Australia, with their distribution primarily influenced by sea change and urbanization. Understanding the trends in NORC distribution can assist the government in developing effective and localized policies and interventions to help older Australians to better age in place.

Consumers often cite cognitive improvements as reasons for making dietary changes or using dietary supplements, a motivation that if leveraged could greatly enhance public health. However, rarely is it considered whether standardized cognitive tests that are used in nutrition research are aligned to outcomes of interest to the consumer. This knowledge gap presents a challenge to the scientific substantiation of nutrition-based cognitive health benefits. Here we combined focus group transcript review using reflexive thematic analysis and a multidisciplinary expert panel exercise to evaluate the applicability of cognitive performance tools/tasks for substantiating the specific cognitive benefits articulated by consumers with the objectives to (1) understand how consumers comprehend the potential benefits of nutrition for brain health, and (2) determine the alignment between consumers desired brain benefits and validated tests and tools. We derived a ‘Consumer Taxonomy of Cognitive and Affective Health in Nutrition Research’ which describes the cognitive and affective structure from the consumers perspective. Experts agreed that validated tests exist for some consumer benefits including focused attention, sustained attention, episodic memory, energy levels, and anxiety. Prospective memory, flow, and presence represented novel benefits that require the development and validation of new tests and tools. Closing the gap between science and consumers and fostering co-creative approaches to nutrition research are critical to the development of products and dietary recommendations that support realizable cognitive benefits that benefit public health.

Through a case study on Bribie Island in Queensland, Australia, this study investigates Naturally Occurring Retirement Communities (NORCs) as a viable alternative for ageing-in-place. Aim: The objectives were to investigate why older adults relocate to Bribie Island, how they perceive their living environment, and their future relocation intentions. Method: The research data were attained through semi-structured interviews with 21 Bribie Island residents, aged 65 and older. These data provided the basis for an in-depth understanding of the residents’ perspectives and experiences, with respect to their community and living conditions. Results: The findings indicate that, overall, the participants expressed a high level of satisfaction with their current living environment; however, they also highlight areas for improvement, particularly the transportation and healthcare facilities. Significantly, most respondents confirmed their desire and intention to continue residing on the island. Conclusion: As exemplified by this Bribie Island case study, this study confirms that NORCs offer desirable settings for ageing-in-place. Recognizing the diversity and range of personal preferences, this study emphasizes the importance of ongoing research to develop responsive, inclusive, and supportive environments, to strategically improve the amenities within future NORCs.

This work aimed to reveal the heterotrophic nitrification and aerobic denitrification activities in a salt-tolerant strain, Tritonibacter mobile HN1, isolated from mariculture sludge by using a pure culture method. Strain HN1 showed the removal rates of ammonia, nitrite, nitrate, and total nitrogen of 98.22%, 100%, 95.71%, and 86.63%, respectively, with the carbon source of sodium citrate or sodium succinate, ratio of carbon to nitrogen of 15, salinity of 3%, temperature of 30 °C, shaking speed of 120 rpm, and pH of 8. The genes of narG, narH, narI, nirS, norB, norC, nosZ, glnA, and GltB were found in the genome sequence of strain HN1, confirming the pathways of nitrogen assimilation, heterotrophic nitrification, and aerobic denitrification. In addition, two nitrifying genes, amo and nap, were missing in the genome of Tritonibacter mobile HN1, indicating that HN1 may have novel genes for this function. This study showed that HN1 had the potential to remove nitrogen contaminants in saline environments and was the first Tritonibacter mobilis strain with heterotrophic nitrification and aerobic denitrification capabilities.

Higher education has been shown to have neuroprotective effects, reducing the risk of Alzheimer’s and Parkinson’s diseases, slowing the rate of age-related cognitive decline, and is associated with lower rates of early mortality. In the present study, the association between higher education, fragile X messenger ribonucleoprotein 1 (FMR1) cytosine–guanine–guanine (CGG) repeat number, and mortality before life expectancy was investigated in a population cohort of women born in 1939. The findings revealed a significant interaction between years of higher education and CGG repeat number. Counter to the study’s hypothesis, the effects of higher education became more pronounced as the number of CGG repeats increased. There was no effect of years of higher education on early mortality for women who had 25 repeats, while each year of higher education decreased the hazard of early mortality by 8% for women who had 30 repeats. For women with 41 repeats, the hazard was decreased by 14% for each additional year of higher education. The interaction remained significant after controlling for IQ and family socioeconomic status (SES) measured during high school, as well as factors measured during adulthood (family, psychosocial, health, and financial factors). The results are interpreted in the context of differential sensitivity to the environment, a conceptualization that posits that some people are more reactive to both negative and positive environmental conditions. Expansions in CGG repeats have been shown in previous FMR1 research to manifest such a differential sensitivity pattern. Full article

BEND3 is a transcription factor that plays a critical role in the regulation of gene expression in mammals. While there is limited research on the role of BEND3 as a tumor suppressor or an oncogene and its potential role in cancer therapy is still emerging, several studies suggest that it may be involved in both the processes. Its interaction and regulation with multiple other factors via p21 have already been reported to play a significant role in cancer development, which serves as an indication of its potential role in oncogenesis. Its interaction with chromatin modifiers such as NuRD and NoRC and its role in the recruitment of polycomb repressive complex 2 (PRC2) are some of the additional events indicative of its potential role in cancer development. Moreover, a few recent studies indicate BEND3 as a potential target for cancer therapy. Since the specific mechanisms by which BEND3 may contribute to cancer progression are not yet fully elucidated, in this review, we have discussed the possible pathways BEND3 may take to serve as an oncogenic driver or suppressor.

Two parallel public health epidemics affecting the United States include the COVID-19 pandemic and a rise in substance use disorders (SUDs). Limited research has examined the potential relationship between these two epidemics. Our objective was therefore to perform an exploratory study in order to examine the association between public stigma toward people with a past history of opioid, methamphetamine, cocaine, and alcohol use disorder and COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 6515) completed a survey which assessed the degree of negative perceptions toward individuals with a past history of substance use disorders (referred to as substance use stigma) and COVID-19 vaccine hesitancy, along with variables such as racial prejudice, source of health news, and other demographics. We evaluated four multivariable logistic regression models to predict COVID-19 vaccine hesitancy, utilizing substance use stigma toward opioids, methamphetamine, cocaine, and alcohol use as independent variables. We found that COVID-19 vaccine hesitancy was positively associated with substance use stigma toward opioid (AOR = 1.34, p < 0.05), methamphetamine (AOR = 1.40, p < 0.01), and cocaine (AOR = 1.28, p < 0.05) use, but not alcohol use (AOR = 1.06, n.s.). Predictive models that incorporate substance use stigma may therefore improve our ability to identify individuals that may benefit from vaccine hesitancy interventions. Future research to understand the underlying reasons behind the association between substance use stigma and COVID-19 vaccine hesitancy may help us to construct combined interventions which address belief systems that promote both substance use stigma and vaccine hesitancy.

Staphylococcus species are major pathogens with increasing importance due to the rise in antibiotic resistance. Whole genome sequencing and genome-scale annotation are promising approaches to study the pathogenicity and dissemination of virulence factors in nosocomial methicillin-resistant and multidrug-resistant bacteria in intensive care units. Draft genome sequences of eight clinical S. aureus strains were assembled and annotated for the prediction of antimicrobial resistance genes, virulence factors, and phylogenetic analysis. Most of the studied S. aureus strains displayed multi-resistance toward the tested drugs, reaching more than seven drugs up to 12 in isolate S22. The mecA gene was detected in three isolates (S14, S21, and S23), mecC was identified in S8 and S9, and blaZ was commonly identified in all isolates except strain S23. Additionally, two complete mobile genomic islands coding for methicillin resistance SCCmec Iva (2B) were identified in strains S21 and S23. Numerous antimicrobial resistance genes (norA, norC, MgrA, tet(45), APH(3′)-IIIa, and AAC(6′)-APH(2″)) were identified in chromosomes of different strains. Plasmid analysis revealed the presence of blaZ, tetK, and ermC in different plasmid types, located in gene cassettes containing plasmid replicons (rep) and insertion sequences (IS). Additionally, the aminoglycoside-resistant determinants were identified in S1 (APH(3′)-IIIa), while AAC(6)-APH(2″) was detected in strains S8 and S14. The trimethoprim (dfrC) resistance gene was detected in S. aureus S21, and the fosfomycin (fosB) resistance gene was detected only in S. aureus S14. We also noted that S. aureus S1 belongs to ST1-t127, which has been reported as one of the most frequent human pathogen types. Additionally, we noted the presence of rare plasmid-mediated mecC-MRSA in some of our isolates. Full article

Scant research exists on COVID-19 vaccine hesitancy among law enforcement officers, hindering health messaging development for officers and, by extension, the communities they serve. This paper’s goal was to address this gap by providing the necessary data to better under hesitancy to guide training and policy interventions for officers. The objective was to conduct the first nationally representative survey of officers on COVID-19 vaccine hesitancy and its correlates. We collected data from February 2021 to March 2022 on officer COVID-19 vaccine hesitancy and examined their responses in terms of sociodemographic factors, health status, and job characteristics. We found that 40% of officers were COVID-19 vaccine hesitant. We found that officers with higher education, older officers, officers with more law enforcement experience, officers who received recent health checkups, and commanders (compared to line officers) were less likely to be COVID-19 vaccine hesitant. Critically, officers working in law enforcement agencies that provided masks for COVID-19 protection were less likely to be COVID-19 vaccine hesitant (compared to agencies not providing masks). Ongoing research is needed to understand how evolving attitudes and barriers toward vaccination change over time for officers and to test messaging to better align officers with health guidelines.

COVID-19 continues to be a public health concern in the United States. Although safe and effective vaccines have been developed, a significant proportion of the US population has not received a COVID-19 vaccine. This cross-sectional study aimed to describe the demographics and behaviors of Minnesota adults who have not received the primary series of the COVID-19 vaccine, or the booster shot using data from the Minnesota COVID-19 Antibody Study (MCAS) collected through a population-based sample between September and December 2021. Data were collected using a web-based survey sent to individuals that responded to a similar survey in 2020 and their adult household members. The sample was 51% female and 86% White/Non-Hispanic. A total of 9% of vaccine-eligible participants had not received the primary series and 23% of those eligible to receive a booster had not received it. Older age, higher education, better self-reported health, $75,000 to $100,000 annual household income, mask-wearing, and social distancing were associated with lower odds of hesitancy. Gender, race, and previous COVID-19 infection were not associated with hesitancy. The most frequently reported reason for not receiving a COVID-19 vaccination was safety concerns. Mask-wearing and being age 65 or older were the only strong predictors of lower odds of vaccine hesitancy for both the primary series and booster analyses. Full article

Background: Opioid overdose rates have steadily been increasing in the United States (US) creating what is considered an overdose death crisis. The US has a mixture of public health and punitive policies aimed to address opioid use and the overdose crisis, yet little is known about public opinion relating to opioid use and policy support. Understanding the intersection of public opinion about opioid use disorder (OUD) and policy can be useful for developing interventions to address policy responses to overdose deaths. Methods: A national sample of cross-sectional data from the AmeriSpeak survey conducted from 27 February 2020 through 2 March 2020 was analyzed. Measures included attitudes toward OUD and policy beliefs. Latent class analysis, a person-centered approach, was used to identify groups of individuals endorsing similar stigma and policy beliefs. We then examined the relationship between the identified groups (i.e., classes) and key behavioral and demographic factors. Results: We identified three distinct groups: (1) “High Stigma/High Punitive Policy”, (2) “High Stigma/Mixed Public Health and Punitive Policy”, and (3) “Low Stigma/High Public Health Policy”. People with higher levels of education had reduced odds of being in the “High Stigma/High Punitive Policy” group. Conclusion: Public health policies are most effective in addressing OUD. We suggest targeting interventions toward the “High Stigma/Mixed Public Health and Punitive Policy” group since this group already displays some support for public health policies. Broader interventions, such as eliminating stigmatizing messaging in the media and redacting punitive policies, could reduce OUD stigma among all groups. Full article
