Lingering Effects of Loss? Widowhood and Substance Use in the LGB Population

Little is known about widowhood's effects on externalizing expressions of distress, like substance use, among sexual minorities. Our study is the first to address this issue using a large national sample of LGB individuals living in the United States. Using the 2010 Aging with Pride: National Health, Aging, and Sexuality/Gender Study ( n = 2,258), we ran logistic regression models predicting current smoking, past 30-day binge drinking, and past year drug use. Widowhood predicted higher odds of drug use. These results were found for currently partnered individuals, suggesting that widowhood's effects are not completely offset by current partnership. In contrast, widowhood did not predict smoking or binge drinking. All results held for women and men. Results suggest that LGB widowhood's effects on substance use vary by current partner status and substance type. These findings contrast with those of studies examining widowhood's effects on internalized expressions of distress, which consistently find detrimental effects.

Luteimonas flava sp. nov. and Aquilutibacter rugosus gen. nov., sp. nov., isolated from freshwater environments in China and re-examining the taxonomic status of genera Luteimonas and Lysobacter

Three Gram-stain-negative, aerobic, short rod-shaped and motile strains (FXH3WT, SHGZ20W and SMYT11WT) were isolated from freshwater environments in China. Comparisons based on the 16S rRNA gene sequences indicated that strains FXH3WT and SHGZ20W showed the highest 16S rRNA gene sequence similarity of about 99.6% to ‘Luteimonas cellulosilyticus’ MIC 1.5, and strain SMYT11WT showed the highest 16S rRNA gene sequence similarity of 99.8% to Luteimonas fraxinea D4P002T, respectively. Observing the phylogenetic trees reconstructed based on the 16S rRNA gene sequences, the species of genera Luteimonas and Lysobacter were not monophyletic and often mixed together. The further reconstructed phylogenomic tree and Genome Taxonomy Database also showed that the species of both genera were polyphyletic, implying that the current taxonomic status of the species of both genera was questionable. The calculated OrthoANIu, digital DNA–DNA hybridization and average amino acid sequence identity (AAI) values supported that strains FXH3WT and SHGZ20W should belong to the same novel species and strain SMYT11WT should also represent an independent novel species. Combining the AAI values and phylogenomic analyses, the species of genera Luteimonas and Lysobacter should be reassigned to 12 genera (Luteimonas, Lysobacter, Cognatiluteimonas, Noviluteimonas, Pseudoluteimonas, Solilutibacter, Agrilutibacter, Cognatilysobacter, Marilutibacter, Novilysobacter, Montanilutibacter and Aerolutibacter). The AAI values 69.5–76.0% were also proposed as the Lysobacteraceae-specific thresholds for genus delineation. Strain SMYT11WT should represent a novel species of the genus Luteimonas, for which the name Luteimonas flava sp. nov. (type strains SMYT11WT=GDMCC 1.4275T=KCTC 8304T) is proposed. Strains FXH3WT and SHGZ20W should represent a novel species of a new genus Aquilutibacter rugosus gen. nov., sp. nov. The type strain of the type species is FXH3WT (=GDMCC 1.4096T=KCTC 8154T).

Determinants of long‐term paramagnetic rim lesion evolution in people with multiple sclerosis

AbstractObjectiveBaseline paramagnetic rim lesion (PRL) load predicts disease progression in people with multiple sclerosis (pwMS). Understanding how PRLs relate to other known MS‐related factors, and the practical utility of PRLs in clinical trials, is crucial for informing clinical decision‐making and guiding development of novel disease‐modifying treatments (DMTs).MethodsThis study included 152 pwMS enrolled in a larger prospective, longitudinal cohort study who had 3T MRI scans and clinical assessments at baseline and 5‐ or 10‐year follow‐ups. PRLs were identified on baseline 3T quantitative susceptibility maps and classified as persisting, disappearing, or newly appearing at follow‐up. The relationships between PRL evolution and clinical, radiological, environmental, and genetic characteristics were assessed, and clinical trial sample sizes were estimated using PRL appearance or disappearance as outcome measures.ResultsDMT use was associated with lower odds of new PRL appearance (for high‐efficacy DMTs: odds ratio = 0.088, p = 0.024), but not disappearance. Current smoking status was associated with greater baseline PRL number (B = 0.527 additional PRLs, p = 0.013). A 24‐month clinical trial in people with progressive MS for a DMT that doubles the rate of PRL rim disappearance would require an estimated 118 people with progressive MS per group at 80% statistical power.InterpretationEarly MS diagnosis and subsequent DMT initiation may reduce new chronic active inflammation. However, the utility of PRL disappearance or new PRL appearance as outcome measures in clinical trials is limited by potentially large sample sizes that are needed for moderate efficacy drugs.

Parental awareness on myopia prevention and control among 350 children

AIM: To understand the current situation of parental perspectives, knowledge, and practices concerning myopia prevention and control for both pre- and school-aged children. METHODS: This study was a cross-sectional survey that involved children aged 0 to 15y and their parents. Participants were required to respond to an online questionnaire by scanning a quick response (QR) code. The questionnaire consisted of 25 tick-box questions and was open to response from December 22, 2022, to January 5, 2023. The dioptric traits of the children, the visual status and educational background of the parents, the parental perspectives towards myopia and its risks, and the parents' knowledge and practices related to myopia prevention and control were recorded and measured. The Chi-square test and binomial logistic regression were used for statistics. RESULTS: Totally 350 parents responded to the questionnaire. The prevalence and severity of myopia among the surveyed children exhibited a positive correlation with advancing age (P<0.001 and P=0.004, respectively). Nearly half of parents with myopic children considered myopia did not pose any health threat and could be effectively corrected (P<0.001). Parents who held master's or doctoral degree demonstrated a better understanding of children's vision standards for each age group (P=0.001), and 31.63% of them could undergo initial vision screening for their children during the age of 0 to 3y while parents with bachelor's degree (34.04%) and below (32.43%) mainly initiated the vision examination for their children at the age of 4 to 6y (P=0.05). Parents with master's or doctoral degree also exhibited more rational practices concerning outdoor time (P=0.048) and sleep time (P=0.044). No other significant discrepancy among the different educational groups in additional conceptions of myopia, such as hyperopia reserve, axis length, and corneal curvature alterations. Most parents preferred to employ conventional interventions, such as enhancing indoor lighting condition (80.00%) and ensuring appropriate reading posture and distance (71.71%). CONCLUSION: The current status of parental knowledge and practices about myopia prevention and control remains outdated and deficient. The administrative department should implement efficacious and adaptable measures to enhance parental awareness and foster their commitment towards myopia prevention and control.

The role of the rhizobiome recruited by root exudates in plant disease resistance: current status and future directions.

Root exudates serve as a bridge connecting plant roots and rhizosphere microbes, playing a key role in influencing the assembly and function of the rhizobiome. Recent studies have fully elucidated the role of root exudates in recruiting rhizosphere microbes to enhance plant performance, particularly in terms of plant resistance to soil-borne pathogens; however, it should be noted that the composition and amount of root exudates are primarily quantitative traits regulated by a large number of genes in plants. As a result, there are knowledge gaps in understanding the contribution of the rhizobiome to soil-borne plant disease resistance and the ternary link of plant genes, root exudates, and disease resistance-associated microbes. Advancements in technologies such as quantitative trait loci (QTL) mapping and genome-wide association studies (GWAS) offer opportunities for the identification of genes associated with quantitative traits. In the present review, we summarize recent studies on the interactions of plant and rhizosphere microbes through root exudates to enhance soil-borne plant disease resistance and also highlight methods for quantifying the contribution of the rhizobiome to plant disease resistance and identifying the genes responsible for recruiting disease resistance-associated microbes through root exudates.

South Korea’s Megacorp and super app: Kakao’s paths to market dominance

This paper traces Kakao’s corporate strategies—with a focus on conglomeration and valuation—in order to trace how the company’s trajectory led to its current status as a near-monopoly. Starting as a chat app which now has 43 million active users in South Korea, Kakao became a conglomerate by expanding its operations across different business sectors such as transportation, entertainment, fintech, etc. Kakao’s diversification of businesses and conglomeration should be understood in relation to its corporate strategies and forms, not as the natural outcome of technological innovation. Aspiring to become an entertainment conglomerate, not just a platform company, Kakao has expanded the scope of its business by acquiring start-ups and competitors, spinning off in-house startups as subsidiaries, and making strategic mergers between subsidiaries. Kakao has also placed greater focus on boosting valuation rather than profitability, a crucial strategy for leveraging high valuations to consolidate its market dominance. Tracing Kakao’s affinities to chaebol, I further propose a framework for thinking about the relationship between the state, tech, and finance. Collusion between the state and tech has occurred through deregulation, which has allowed tech companies to become financial capital.

The Prevalence of Fluoroquinolone-Resistant E. coli in Animals and Animal Products: A Systematic Review and Meta-Analysis

Background: Biological contamination of foods is a serious problem for human health. Animal and animal products may be contaminated by these biological and chemical contaminants. One of the most important causes of foodborne illness in humans is Escherichia coli. Fluoroquinolones can be used as a suitable treatment for enteric infections in food-producing livestock. We aimed to evaluate the current status of resistance of E. coli strains isolated from animals and animal products to fluoroquinolone in Iran. Methods: A systematic search was conducted using the Web of Science, PubMed, Embase, Google Scholar, and Scopus databases from 2000 to Oct 2020. Nineteen studies were selected based on the inclusion criteria and analysis by Comprehensive Meta-Analysis. Results: Based on the data analysis, The rates of antibiotic resistance in animal strains were as follows: Flumequine (75.1%), Enrofloxacin (55.2%), Danofloxacin (48.1%), Ciprofloxacin (48.4%), and Norfloxacin (52.9%). Next, the rates of quinolone resistance among E. coli strains isolated from animal products were Norfloxacin (45.5%), Ciprofloxacin (44.5%), and Enrofloxacin (60.9%). Based on the funnel plots and Egger's test, there was no significant publication bias. Conclusion: We finally concluded that antibiotic resistance in commensal E. coli is related to the overuse of antibiotics in livestock, especially fluoroquinolones.

Orchid phylogenetics and evolution: history, current status and prospects.

Orchidaceae are one of the two largest families of angiosperms; they exhibit a host of changes -- morphological, ecological and molecular -- that make them excellent candidates for evolutionary study. Such studies are most effectively performed in a phylogenetic context, which provides direction to character change. Understanding of orchid relationships began in the pre-evolutionary classification systems of the 1800's that were based solely on morphology, and now is largely based on genomic analysis. The resulting patterns have been used to update family classification and to test many evolutionary hypotheses in the family. Recent analyses with dense sampling and large numbers of nuclear loci have yielded well-supported trees that have confirmed many longstanding hypotheses and overturned others. They are being used to understand evolutionary change and diversification in the family. These include dating the origination of the family, analysis of change in ecological habit (from terrestrial to epiphytic and back again in some cases), revealing significant plastid genome change in leafless holomycotrophs, studying biogeographic patterns in various parts of the world, and interpreting patterns of fungal associations with orchids. Understanding of orchid relationships has progressed significantly in recent decades, especially since DNA sequence data have been available. These data have contributed to an increasingly refined classification of orchids and the pattern has facilitated many studies on character evolution and diversification in the family. Whole genome studies of the family are just beginning and promise to reveal fine-level details underlying structure and function in these plants, and, when set in a phylogenetic context, provide a much richer understanding of how the family has been so successful in diversification.

Comprehensive construction of biologically active α‐carbolines from synthetic and natural origin

α‐Carboline is an important scaffold present in various synthetic and naturally obtained bioactive compounds possessing a wide range of pharmacological properties. Hence, in the current comprehensive review, we intend to present the main routes to the synthesis of α‐carboline analogs based on various pathways such as pyrrole, benzene, and pyridine ring annulation. The pathways include either or combinations of transition metal‐catalyzed amination/arylation, Graebe‐Ullmann reaction (thermal pyrolysis, photochemical cyclization), Diels‐Alder cycloaddition and condensation reactions, N‐Heterocyclic carbene catalysed reactions, decarboxylative annulation, etc. of substituted benzene, pyridine, quinoline, and indole derivatives in order to compare the potential of synthetic routes of this series and consolidate the development, current status and perspectives for the design of α‐carboline analogs. Various pharmacological and spectroscopy functions of the compounds belonging to this class are summarized herewith. It also discusses the synthesis of functionalized bioactive naturally obtained hetero‐annulated α‐ carbolines.

The 'Zero consumption' phenomenon of elderly people's sports and leisure in the Yangtze River delta region

This study investigates the current status of the "zero consumption" phenomenon in sports and leisure activities among elderly individuals in the Yangtze River Delta region, analyzing its characteristics and underlying causes. Data related to the consumption of sports and leisure activities among the elderly in this region were obtained through methods such as questionnaires and interviews. The results indicate that "zero consumption" in elderly sports and leisure activities is a common social phenomenon in the Yangtze River Delta region of China. It is not only a result of economic income constraints but also a consumption trend formed under the influence of various factors such as aging and declining physical fitness. While "zero consumption" does not significantly affect the elderly' s participation in sports and leisure activities, it may to some extent impact the diversification of these activities. Given the current participation status of elderly individuals in sports and leisure activities in China, it is still unable to play a crucial leading role in the development of the leisure industry as seen in developed countries.

From past to present, exploring the applications of mupirocin ointment: A comprehensive review

Mupirocin (MUP), a potent antibacterial agent, has been a cornerstone of topical antimicrobial therapy for several decades. As an older, yet widely used antibiotic, MUP has exhibited efficacy against various bacterial strains, making it a versatile tool in the management of a range of infections. The review synthesizes available literature to highlight the evolution of MUP, from its initial discovery to its current status as a go-to topical antibiotic. In the era of rising antibiotic resistance, MUP is positioned as a valuable therapeutic option due to its broad-spectrum activity against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). Emphasis is placed on its distinctive role in different infections, enhanced efficacy with different additives, and newer drug delivery strategies.In addition to its classical applications in impetigo and other superficial skin infections, this review delves into emerging indications and novel uses of MUP, potentially expanding its clinical utility. The exploration of combination therapies, alternative formulations, and ongoing research endeavors will contribute to a forward-looking perspective on the role of MUP in future antimicrobial strategies.

Lung Point of Care Ultrasound (POCUS) in Cardiorespiratory Physiotherapy and Respiratory Therapy Practices: Current Status and Future Directions

Lung Point of Care Ultrasound (POCUS) strongly influences physiotherapy and respiratory therapy clinical decision-making in the intensive care unit (ICU). The uptake of Lung POCUS training by physiotherapists and respiratory therapists is low in some countries, often due to many barriers to its implementation. The safe and appropriate integration of Lung POCUS into physiotherapy and respiratory therapy clinical practice may be achieved by various means. This article describes the pathway for physiotherapists to become Lung POCUS-accredited in Australia, focusing on a novel fast-track approach that may apply internationally and in other professions, such as respiratory therapy. While a fast-track approach is resource intensive, such resource allocation may be justified to support the growth of Lung POCUS in physiotherapy and respiratory therapy practice where mentor support may be inconsistent, lacking, or absent.

Energy transition governance in the ASEAN: current status and future prospects

PurposeA study of Association of Southeast Asian Nations (ASEAN) member states’ (AMS) norm entrepreneurial practices regarding the energy transition to reveal insights into its current and future governance.Design/methodology/approachUnderstanding why the notion of an energy transition has garnered support, and importantly, knowing what this means for the future requires reviewing the forces of norm entrepreneurship at play. By adopting a constructivist lens, this article undertakes a comparative analysis of the “modes of transmission” of the energy transition amongst AMS.FindingsASEAN nations have in many respects been at the vanguard of the energy transition. Yet the governments themselves demonstrate both norm entrepreneurial and antipreneurial characteristics. Notwithstanding this mix, there are extant opportunities for “intraconnection” – in the form of cooperation between AMS and “interconnection” – in the form of cooperation between AMS and other state and non-state actors.Practical implicationsThis article underscores the importance of partnerships in the energy transition: both in enabling AMS to meet their respective nationally determined contributions (NDCs) but also crucially in catalysing action amongst a broader swathe of countries.Originality/valueApplying the lens of norm entrepreneurship to the ASEAN context, including introducing novel conceptions of “conductive” practices that drive the energy transition and “resistive” practices that slow it down.

Evaluation of the osteoarthritis disease burden in China from 1990 to 2021: based on the Global Burden of Disease Study 2021

ObjectiveThis study aims to understand the current status and trend of the disease burden of osteoarthritis (OA) in people over 30 years old in China from 1990 to 2021 and identify the priority population groups, to provide reference data for the prevention and treatment of OA in China.MethodsThe Global Burden of Disease Study 2021 was used to describe the incidence, prevalence, and disability-adjusted life years (DALYs) of OA in adult aged 30 years or older in China by sex and age groups, which was used to analyze the disease burden of OA from 1990 to 2021. The joinpoint regression model and age-period-cohort model were used to characterize the temporal trend.ResultsIn 2021, the number of OA prevalence in China was about 152.85 million, and the number of incidences was about 11.65 million. The age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR) and age-standardized DALYs rate (ASDR) of OA in China are lower than those in developed countries such as Korea, the United States of America and Japan, but higher than those in India. Knee osteoarthritis had the highest ASPR and ASDR. The highest incidence rate was 50–54 years, and the highest prevalence and DALYs rate were in the age group of patients over 95 years old. The incidence rate of women in all age groups is higher than that of men. From 1990 to 2021, the ASIR, ASPR and ASDR of OA in China roughly showed an increasing trend year by year. The age-period-cohort analysis showed that the peak age groups for longitudinal age incidence of OA in China from 1992 to 2021 were 50–54 years and 80–84 years. We found that the OA incidence was highest in the period 2017–2021.ConclusionThe disease burden of OA in those over 30 years old in China from 1990 to 2021 will become more and more serious, and the target population for primary prevention is the female population under 50 years old. The development of a scientific and effective comprehensive prevention and treatment program for OA is imminent.

Harnessing AI for advancing pathogenic microbiology: a bibliometric and topic modeling approach

IntroductionThe integration of artificial intelligence (AI) in pathogenic microbiology has accelerated research and innovation. This study aims to explore the evolution and trends of AI applications in this domain, providing insights into how AI is transforming research and practice in pathogenic microbiology.MethodsWe employed bibliometric analysis and topic modeling to examine 27,420 publications from the Web of Science Core Collection, covering the period from 2010 to 2024. These methods enabled us to identify key trends, research areas, and the geographical distribution of research efforts.ResultsSince 2016, there has been an exponential increase in AI-related publications, with significant contributions from China and the USA. Our analysis identified eight major AI application areas: pathogen detection, antibiotic resistance prediction, transmission modeling, genomic analysis, therapeutic optimization, ecological profiling, vaccine development, and data management systems. Notably, we found significant lexical overlaps between these areas, especially between drug resistance and vaccine development, suggesting an interconnected research landscape.DiscussionAI is increasingly moving from laboratory research to clinical applications, enhancing hospital operations and public health strategies. It plays a vital role in optimizing pathogen detection, improving diagnostic speed, treatment efficacy, and disease control, particularly through advancements in rapid antibiotic susceptibility testing and COVID-19 vaccine development. This study highlights the current status, progress, and challenges of AI in pathogenic microbiology, guiding future research directions, resource allocation, and policy-making.
