Peri-levator Betamethasone Versus Triamcinolone Injection in Management of Thyroid Eye Disease-related Upper Eyelid Retraction Without Proptosis.

PURPOSE: To compare the efficacy of peri-levator injection of both betamethasone and triamcinolone in the management of thyroid eye disease-related upper eyelid retraction without proptosis. METHODS: This prospective, double-blind, randomized clinical trial was conducted at Assiut University Hospital, Upper Egypt in the period between December 2021 and October 2023. The study included 47 patients (56 eyes) and was divided into 2 groups. In group A, 1 ml betamethasone was injected into the peri-levator area, while in group B, 1 ml triamcinolone was injected. The injection was repeated every month for up to 5 injections if there was an improvement in margin reflex distance 1 (MRD1). The injection was stopped if MRD1 reached the normal value or if 2 successive injections caused no improvement in MRD1. The postinjection outcome was divided into: 1) effective if MRD1 reached the normal ≤4.5 mm; 2) partially effective if MRD1 was improved but did not reach the normal; and 3) ineffective if there was no improvement in MRD1. The follow up ranged from 6 to 20 months. RESULTS: In group A, the injection was effective in 26 eyes (92.9%) and partially effective in 2 eyes (7.1%). In group B, the injection was effective in 17 eyes (60.7%), partially effective in 6 eyes (21.4%), and ineffective in 5 eyes (17.9%). The mean number of injections was significantly lower in group A than in group B: 1.61 ± 0.50 versus 2.36 ± 1.16. CONCLUSIONS: This study results suggest that betamethasone is more effective with a smaller number of injections than triamcinolone in the management of thyroid eye disease-related upper eyelid retraction.

Bacillus sonorinses derived exopolysaccharide enhances cell cycle arrest, apoptosis, necrosis, autophagy and COX-2 down regulation in liver cancer cells.

Background: Hepatocellular carcinoma (HCC) is one of the most serious types of cancer that accounts for numerous cancer deaths worldwide. HCC is poorly prognosed and is a highly chemotherapy-resistant tumor. Therefore, new treatments are urgently needed. Exopolysaccharides (EPS-1) produced from the novel Bacillus sonorensis strain was found to exhibit chemopreventive effects against cancer. Objective: Evaluating the anti-cancer cytotoxic effect of exopolysaccharides (EPS-1) produced by the newly studied Bacillus sonorensis strain SAmt2. Methods: The cytotoxic activity was investigated through cell cycle, apoptosis, and autophagy analyses using flow cytometry technique. Also, the effect of EPS-1 on Huh7 release of COX-2 was examined using ELISA. Results: Our results revealed that EPS-1exhibit an anti-proliferative effect on Huh7 cells through decreasing the percentage of cells at the S-phase and G2 phase, while increasing the cell population at the sub-G1 and G1 phases. Apoptosis analysis showed that EPS-1 increased necrotic and apoptotic cell fractions in EPS-1 treated Huh7. In addition, it induced significant autophagic cell death in the Huh7.Finally, antiproliferative and apoptosis induction results were supportedby ELISA assay results where the protein level of COX-2 was declined. Conclusion: : In conclusion, EPS-1 derived from B. sonorensis SAmt2, is a promising proliferation inhibitor of Huh7 cells with potential anticancer effects.

Gender differences in presentation, management, and outcomes among Egyptian patients with acute coronary syndrome: a single-centre registry.

BACKGROUND: Despite a significant rise in cardiovascular disease (CVD)-related mortality in low- and middle-income countries (LMICs), data are scarce regarding the quality of care provided, particularly for women. METHODS: This is a prospective observational, cross-sectional study. Acute coronary syndrome (ACS) patients presented to the Cardiology Department at Tanta University, Egypt, between September 1, 2023, and December 31, 2023, were enrolled. The study assessed gender disparities by comparing men and women regarding presentation, management, and major adverse cardiovascular events (MACE) occurrence during hospitalization and 30 days after discharge. RESULTS: A total of 400 ACS patients were included, with 29.5% being women. Women were comparatively older (59 ± 9 years vs. 55 ± 13 years), with a significantly higher prevalence of hypertension (70.3% vs. 47.5%) and diabetes (55% vs. 36.8%). Non-ST-segment elevation myocardial infarction (Non-STEMI) was more common in women (35.29% vs. 21%). Dyspnea was expressed by 34.4% of women (vs. 21.35% of men). Women were hospitalized later (9.29 h vs. 6.74 h). In-hospital outcomes were poorer for women with worse NYHA classes III and IV. Additionally, the odds ratio (OR) for in-hospital cardiac mortality was 0.303 (95% CI 0.103-0.893) for women compared to men. However, a one-month follow-up for MACE post-hospital discharge did not indicate significant gender differences. CONCLUSIONS: The current study suggests that women with ACS in Egypt exhibit a higher risk profile for CVD compared to men and tend to present later with atypical symptoms. Women additionally experience poorer in-hospital MACE and higher cardiac mortality. Therefore, increasing awareness about ACS syndrome and eliminating obstacles that delay hospital admission are imperative.

Key considerations for the future of mental health epidemiology.

Psychiatric epidemiology has led to substantial progress in our understanding of the causes of mental health disorders. The increasing sophistication of etiologic psychiatric research has been accompanied by a greater focus on the biological and genetic causes of psychiatric disorders, to some extent diverging from field's early focus on the burden of poor mental health due to a breadth of social and economic conditions. We argue that the moment is ripe for advancing a mental health epidemiology that can reconnect the field to these earlier-and still central-concerns, while retaining the strengths of psychiatric epidemiology. Embracing five considerations can help advance the evolving field of mental health epidemiology. First, conceptually, an ambitious vision for the future of the field necessitates investment in refining our definitions and methodologies. Second, there is a need for a renewed focus on the macrosocial determinants of mental health. Third, a deeper engagement with mental health inequities should be central to our scholarship. Fourth, the field would benefit from a more deliberate assessment of the mechanisms leading to adverse mental health outcomes, which can then be used to inform novel interventions. Finally, realizing this future is contingent upon a wholesale commitment to studying population mental health globally.

Higher Number of Children is Associated with Increased Risk of Generalization Deficits in Older African American Women.

OBJECTIVES: The objectives of this project were to: (1) examine the relationship between the number of biological children and hippocampal-dependent cognitive performance among older African American women and (2) determine the influence of socioeconomic status (i.e., age, education, marital status, median household income), if any, on this relationship. METHODS: 146 cognitively unimpaired African American women aged 60 and older were recruited from the greater Newark area and reported their number of biological children, marital status, educational level, and age. We retrieved median household income from census tract data based on the participants' addresses. Participants' cognitive performance was assessed using the Rey Auditory Verbal Learning Test (RAVLT) long delay recall and a Rutgers generalization task (Concurrent Discrimination and Transfer Task). RESULTS: As the number of biological children a woman has had increases, the number of generalization errors also increased, indicating poorer hippocampal-dependent cognitive performance when controlling for age, education, marital status, and median household income. There was no significant relationship between the number of children and performance on a standardized neuropsychological measure of episodic memory (RAVLT), although education was a significant covariate. DISCUSSION: Generalization tasks may better capture early changes in cognitive performance in older African American women who have had children than standardized neuropsychological assessments. This finding may be explained by the fluctuations in estrogen associated with having children. Future studies should explore how these findings can be applied to protecting cognitive function and preventing AD in older African American women who have had children.

Perceptions of the determinants of health across income and urbanicity levels in eight countries.

BACKGROUND: A clear understanding of public perceptions of the social determinants of health remains lacking. This paper aimed to describe the relationship between income and urbanicity levels and public views of the determinants of health in eight middle-and high-income countries that varied across multiple characteristics. METHODS: We conducted a cross-sectional online survey in Brazil, China, Germany, Egypt, India, Indonesia, Nigeria, and the United States. Respondents were asked to select what they considered to be most important for health out of a list of ten determinants. We stratified the results by income and urbanicity levels and tested significance of differences between groups using two-tailed χ2 tests. Multivariable logistic regression models tested associations between demographic factors and the likelihood of respondents selecting the genetics, healthcare, income and wealth, or social support determinants. RESULTS: Here we show 8753 respondents across eight countries. Rankings of determinants are similar across income groups, except for two determinants. Respondents in the highest income group rank genetics in higher proportions (32.4%, 95%CI: 29.0%,35.8%) compared to other income groups. Conversely, those in lowest income group rank social support more frequently (27.9%, 95%CI: 25.3%,30.7%) than other income groups. Those living in urban settings rank healthcare in higher proportions (61.2%, 95%CI: 59.0%,63.4%) compared to non-urban respondents; meanwhile, higher proportions (26.6%, 95%CI: 24.9%,28.3%) of non-urban respondents rank social support as important for health compared to urban respondents. CONCLUSION: Demographic factors play a role in shaping public views of what affects health. Advancing public understanding about determinants of health requires tailoring public health messaging to account for socioeconomic position within a population.

Various factors determine our health, such as our environment, education, and genetics. Here, we explore how people from different income and urban backgrounds view the factors that affect health. We surveyed participants from Brazil, China, Germany, Egypt, India, Indonesia, Nigeria, and the United States. Respondents selected the most important factors for health from a list of ten choices. Overall, people's views on these factors were comparable across income groups, with exceptions. Those with higher incomes tended to emphasize the importance of genetics more, while lower-income individuals valued social support. People in urban areas prioritized healthcare, while those in non-urban areas valued social support. These findings suggest that factors such as income and where people live influence their views about health determinants. These factors should be considered in public health messaging and strategies to promote health amongst different groups.

News media as a commercial determinant of health.

Commercial determinants of health frameworks aim to identify the features and actions of corporate entities that can influence health. This Viewpoint conceptualises the work of the news media as a set of commercial forces and provides a framework that can help researchers better understand how features and actions of the news media shape health and health equity. We discuss four key features of news media action that can shape health: agenda setting, framing, priming, and tactics of persuasion. Beyond the direct role of the media in shaping health, we also explore pathways (ie, public relation activities, advertising, and economic pressures) in which the media is used by other commercial actors to affect health. A better understanding of how news media operates can help inform efforts to improve media actions to aid in improving population health outcomes.

Depression and assets during the COVID-19 pandemic: A longitudinal study of mental health across income and savings groups.

The prevalence of depression in U.S. adults during the COVID-19 pandemic has been high overall and particularly high among persons with fewer assets. Building on previous work on assets and mental health, we document the burden of depression in groups based on income and savings during the first two years of the COVID-19 pandemic. Using a nationally representative, longitudinal panel study of U.S. adults (N = 1,271) collected in April-May 2020 (T1), April-May 2021 (T2), and April-May 2022 (T3), we estimated the adjusted odds of reporting probable depression at any time during the COVID-19 pandemic with generalized estimating equations (GEE). We explored probable depression-defined as a score of ≥10 on the Patient Health Questionnaire-9 (PHQ-9)-by four asset groups, defined by median income (≥$65,000) and savings (≥$20,000) categories. The prevalence of probable depression was consistently high in Spring 2020, Spring 2021, and Spring 2022 with 27.9% of U.S. adults reporting probable depression in Spring 2022. We found that there were four distinct asset groups that experienced different depression trajectories over the COVID-19 pandemic. Low income-low savings asset groups had the highest level of probable depression across time, reporting 3.7 times the odds (95% CI: 2.6, 5.3) of probable depression at any time relative to high income-high savings asset groups. While probable depression stayed relatively stable across time for most groups, the low income-low savings group reported significantly higher levels of probable depression at T2, compared to T1, and the high income-low savings group reported significantly higher levels of probable depression at T3 than T1. The weighted average of probable depression across time was 42.9% for low income-low savings groups, 24.3% for high income-low savings groups, 19.4% for low income-high savings groups, and 14.0% for high income-high savings groups. Efforts to ameliorate both savings and income may be necessary to mitigate the mental health consequences of pandemics.

Mental Health and U.S. Attitudes Toward Social Determinants of Health Policies.

INTRODUCTION: Research has suggested that individual health may influence policy attitudes, yet the relationship between mental health and policy support is understudied. Clarifying this relationship may help inform policies that can improve the population mental health. To address this gap, this study measures national support for 5 social determinants of health policy priorities and their relation to mental health and political affiliation. METHODS: This study assessed support for 5 policy priorities related to the social determinants of health using a nationally representative survey of US adults (n=2,430) conducted in March-April 2023. Logistic regression was used to estimate the predicted probability of identifying each priority as important, test differences in support by self-rated mental health, and evaluate whether partisanship modified these relationships. Analyses were conducted in 2023. RESULTS: The majority of US adults, across partisan identities, supported 5 policy priorities related to improving the economy (84%), healthcare affordability (77%), improving K-12 education (76%), housing affordability (68%), and childcare affordability (61%). Worse mental health predicted significantly greater support for addressing housing affordability (73.9% vs 66.2%), and partisanship modified the relationship between mental health and support for improving the economy, improving K-12 education, and housing affordability. CONCLUSIONS: In 2023, there was substantial bipartisan support for federal policy action to address the social determinants of health, and worse mental health was related to greater policy support, particularly among Democrats. Federal policymakers have a broad consensus to take action to address the social determinants of health, which may improve the population mental health.

Experience of Personal Loss Due to Drug Overdose Among US Adults.

Importance: Since 1999, over 1 million people have died of a drug overdose in the US. However, little is known about the bereaved, meaning their family, friends, and acquaintances, and their views on the importance of addiction as a policy priority. Objectives: To quantify the scope of the drug overdose crisis in terms of personal overdose loss (ie, knowing someone who died of a drug overdose) and to assess the policy implications of this loss. Design, Setting, and Participants: This cross-sectional study used data from a nationally representative survey of US adults (age ≥18 years), the fourth wave of the COVID-19 and Life Stressors Impact on Mental Health and Well-Being (CLIMB) study, which was conducted from March to April 2023. Main Outcomes and Measures: Respondents reported whether they knew someone who died of a drug overdose and the nature of their relationship with the decedent(s). They also reported their political party affiliation and rated the importance of addiction as a policy issue. Logistic regression models estimated the associations between sociodemographic characteristics and political party affiliation and the probability of experiencing a personal overdose loss and between the experience of overdose loss and the perceived salience of addiction as a policy issue. Survey weights adjusted for sampling design and nonresponse. Results: Of the 7802 panelists invited to participate, 2479 completed the survey (31.8% response rate); 153 were excluded because they did not know whether they knew someone who died of a drug overdose, resulting in a final analytic sample of 2326 (51.4% female; mean [SD] age, 48.12 [0.48] years). Of these respondents, 32.0% (95% CI, 28.8%-34.3%) reported any personal overdose loss, translating to 82.7 million US adults. A total of 18.9% (95% CI, 17.1%-20.8%) of all respondents, translating to 48.9 million US adults, reported having a family member or close friend die of drug overdose. Personal overdose loss was more prevalent among groups with lower income (<$30 000: 39.9%; ≥$100 000: 26.0%). The experience of overdose loss did not differ across political party groups (Democrat: 29.0%; Republican: 33.0%; independent or none: 34.2%). Experiencing overdose loss was associated with a greater odds of viewing addiction as an extremely or very important policy issue (adjusted odds ratio, 1.37; 95% CI, 1.09-1.72) after adjustment for sociodemographic and geographic characteristics and political party affiliation. Conclusions and Relevance: This cross-sectional study found that 32% of US adults reported knowing someone who died of a drug overdose and that personal overdose loss was associated with greater odds of endorsing addiction as an important policy issue. The findings suggest that mobilization of this group may be an avenue to facilitate greater policy change.

A new framework for novel analogues of pazopanib as potent and selective human carbonic anhydrase inhibitors: Design, repurposing rational, synthesis, crystallographic, in vivo and in vitro biological assessments.

Herein, we describe the design and synthesis of novel aryl pyrimidine benzenesulfonamides APBSs 5a-n, 6a-c, 7a-b, and 8 as pazopanib analogues to explore new potent and selective inhibitors for the CA IX. All APBSs were examined in vitro for their promising inhibition activity against a small panel of hCAs (isoforms I, II, IX, and XII). The X-ray crystal structure of CA I in adduct with a representative APBS analogue was solved. APBS-5m, endowed with the best hCA IX inhibitory efficacy and selectivity, was evaluated for antiproliferative activity against a small panel of different cancer cell lines, SK-MEL-173, MDA-MB-231, A549, HCT-116, and HeLa, and it demonstrated one-digit IC50 values range from 2.93 µM (MDA-MB-231) to 5.86 µM (A549). Furthermore, compound APBS-5m was evaluated for its influence on hypoxia-inducible factor (HIF-1α) production, apoptosis induction, and colony formation in MDA-MB-231 cancer cells. The in vivo efficacy of APBS-5m as an antitumor agent was additionally investigated in an animal model of Solid Ehrlich Carcinoma (SEC). In order to offer perceptions into the conveyed hCA IX inhibitory efficacy and selectivity in silico, a molecular docking investigation was also carried out.

Qatar's National Mental Health Survey-The World Mental Health Qatar: Sampling design, instrument adaptation, quality control, and fielding procedures.

OBJECTIVES: The World Mental Health Qatar (WMHQ) study, the first national general population mental health survey in Qatar, was conducted as part of the World Health Organization (WHO) World Mental Health (WMH) Survey Initiative. It was one of the few WMH survey conducted during the COVID-19 pandemic. This paper presents the methodological advances and challenges encountered while conducting the survey by telephone during the pandemic. METHODS: Disproportionate stratified sampling using a national-level cellular telephone frame selected a representative sample of Arabic-speaking adults. Participants were initially contacted via Short Message Service text, followed by telephone interviews. WMH training materials supported a comprehensive training program, and data quality was ensured through a quality control indicator system and extensive monitoring. RESULTS: Over 234 days, 5195 interviews in Arabic were completed, averaging 77 min each. In line with Qatar's population, the majority of participants were non-Qatari residents living in Qatar (72.2%). CONCLUSIONS: A distributed remote Computer Assisted Telephone Interviewing system facilitated centralized quality monitoring and data security. However, the pandemic intensified challenges such as remote management of interviewer productivity, low response rates, and rising survey costs. The findings will inform Qatar's mental health policymakers, and the strategies used to address these challenges offer valuable insights for researchers worldwide.

Feasibility of replacing face-to-face with telephone interviews for the World Mental Health Qatar survey during the COVID-19 pandemic.

OBJECTIVES: We investigated the feasibility of replacing face-to-face with telephone interviews conducted as part of the World Mental Health Qatar (WMHQ) survey and discuss the main methodological changes across the two pilots that were subsequently implemented in the full-scale WMHQ telephone survey. METHODS: We assessed the net mode effect by comparing the lifetime prevalence estimates of the main mental disorder classes (mood and anxiety disorders) and a number of disorders across the two survey pilots conducted prior to and post-pandemic. RESULTS: The main differences in terms of methodology for both pilots stemmed from differences in the survey mode, including questionnaire length, study recruitment method, and fielding team size and structure. These factors influenced response rates and costs. However, the lifetime prevalence estimates and other key indicators of survey results did not differ across modes. CONCLUSIONS: Our findings confirm the comparability of data collected via telephone and face-to-face modes, supporting the adoption of telephone surveys for future mental health studies, particularly in the context of pandemics. They also confirm the feasibility of changing or mixing modes depending on field conditions in future psychiatric epidemiological research.

Twelve-month prevalence, persistence, severity, and treatment of mood and anxiety disorders in Qatar's national mental health study.

OBJECTIVES: To estimate 12-month prevalence, persistence, severity, and treatment of mental disorders and socio-demographic correlates in Qatar. METHODS: We conducted the first national population-based telephone survey of Arab adults between 2019 and 2022 using the Composite International Diagnostic Interview and estimated 12-month DSM-5 mood and anxiety disorders and their persistence (the proportion of lifetime cases who continue to meet 12-month criteria). RESULTS: The 12-month prevalence of any disorder was 21.1% (10.4% mild, 38.7% moderate, and 50.9% severe) and was associated with: younger age, female, previously married, and with persistence of any disorder. Persistence was 74.7% (64.0% mood and 75.6% anxiety) and was significantly associated with secondary education or lower. Minimally adequate treatment received among those with any 12-month mental disorder was 10.6% (74.6% in healthcare and 64.6% non-healthcare sectors). Severity and the number of disorders significantly associated with each other and with treatment received (χ2 = 7.24, p = 0.027) including adequate treatment within the mental health specialty sector (χ2 = 21.42, p < 0.001). CONCLUSIONS: Multimorbidity and sociodemographics were associated with 12-month mental disorder. Treatment adequacy in Qatar are comparable to high-income countries. Low treatment contact indicate need for population-wide mental health literacy programes in addition to more accessible and effective mental health services.

Clinical reappraisal of the composite international diagnostic interview version 3.3 in Qatar's National Mental Health Study.

OBJECTIVES: Lifetime DSM-5 diagnoses generated by the lay-administered Composite International Diagnostic Interview for DSM-5 (CIDI) in the World Mental Health Qatar (WMHQ) study were compared to diagnoses based on blinded clinician-administered reappraisal interviews. METHODS: Telephone follow-up interviews used the non-patient edition of the Structured Clinician Interview for DSM-5 (SCID) oversampling respondents who screened positive for five diagnoses in the CIDI: major depressive episode, mania/hypomania, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Concordance was also examined for a diagnoses of post-traumatic stress disorder based on a short-form versus full version of the PTSD Checklist for DSM-5 (PCL-5). RESULTS: Initial CIDI prevalence estimates differed significantly from the SCID for most diagnoses ( χ 1 2 ${\chi }_{1}^{2}$  = 6.6-31.4, p = 0.010 < 0.001), but recalibration reduced most of these differences and led to consistent increases in individual-level concordance (AU-ROC) from 0.53-0.76 to 0.67-0.81. Recalibration of the short-form PCL-5 removed an initially significant difference in PTSD prevalence with the full PCL-5 (from χ 1 2 ${\chi }_{1}^{2}$  = 610.5, p < 0.001 to χ 1 2 ${\chi }_{1}^{2}$  = 2.5, p = 0.110) while also increasing AU-ROC from 0.76 to 0.81. CONCLUSIONS: Recalibration resulted in valid diagnoses of common mental disorders in the Qatar National Mental Health Survey, but with inflated prevalence estimates for some disorders that need to be considered when interpreting results.

Evaluation of incipient enamel-carious-like lesion treated with hydroxyapatite-chitosan nanocomposite hydrogel.

BACKGROUND: Non-invasive restoration of tooth enamel is a topic of high relevance in dental material science. Multiple approaches have been proposed to reach optimum reconstruction results. The current study was performed to evaluate the cross-sectional microhardness besides mineral quality and content in artificially induced carious enamel after treatment with hydroxyapatite-chitosan (HAp-CS) nanocomposite gel. METHODS: Artificially carious lesions were induced by immersion of teeth in acidic carboxymethyl cellulose gel (pH 4.95-5) for 24- and 72-hours periods. Two different compositions of HAp-CS nanocomposite hydrogel were prepared with two different ratios 50/50 (%) and 70/30 (%), respectively. Additionally, sodium fluoride gel (1000 ppm concentration) was prepared and used as reference. Gels were applied to carious lesions twice/day for 3 min/each. After 45 days of application, surface morphology, energy dispersive x-ray spectroscopy, micro-Raman analysis in addition to cross-sectional microhardness were evaluated. Statistical analysis was performed using two-way ANOVA and Tukey's post hoc statistical tests. RESULTS: Surface morphological evaluation of treated surfaces showed obliteration of surface irregularities. Groups demineralized for 24 hours and treated with 70/30 (HAp-CS) showed highest significant cross-sectional-microhardness (P ≤ 0.05). Evaluated subsurface cross-sectional microhardness showed better mineral quality for groups demineralized for 24 hours and treated with HAp-CS nanocomposite gels. CONCLUSIONS: Nanocomposite gel with 70/30 (HAp-CS) could efficiently improve cross-sectional microhardness and both minerals composition and quality for lesions demineralized for 24 hours. More severely induced lesions, as demineralized for 72 hours, need more powerful agent compositions and/or prolonged application protocols for improvement.

Genetic relatedness and diversity of Capillaria species infecting bayad (Bagrus bajad) in upper Egypt.

BACKGROUND: This study investigates the genetic characteristics of Capillaria isolates from the infected fish, Bagrus bajad, and their relation to human Capillaria philippinensis using Random Amplified Polymorphic DNA (RAPD-PCR) analysis. Fifteen fish Capillaria were isolated and compared to identified human C. philippinensis using six primers: M-are, M-1, G-7, G-11, G-15, and G-18. RESULTS: All six primers successfully amplified DNA, highlighting their efficacy in distinguishing between human and fish Capillaria isolates. The analysis revealed distinctive banding patterns between fish and human isolates, with variations in size and number of DNA fragments. Additionally, genetic similarity analysis showed intriguing patterns of relatedness, with certain pairs exhibiting high similarity percentages. Comparative assessment of RAPD polymorphism demonstrated consistent findings of 100% polymorphism across all primers. The Unweighted Pair Group Method with Arithmetic Mean Algorithm (UPGMA) evaluated the closest relationship between human and fish isolates. These results underscore the utility of RAPD analysis in delineating the genetic diversity among Capillaria isolates from different hosts. CONCLUSION: Overall, this study contributes to our understanding of the genetic variability and relatedness among Capillaria isolates, shedding light on their evolutionary dynamics and zoonotic potential.

Feasibility of Fit24, a Digital Diabetes Prevention Program for Hispanic Adolescents: Qualitative Evaluation Study.

BACKGROUND: Digital health interventions are promising for reaching and engaging high-risk youth in disease prevention opportunities; however, few digital prevention interventions have been developed for Hispanic youth, limiting our knowledge of these strategies among this population. OBJECTIVE: This study qualitatively assessed the feasibility and acceptability of Fit24, a 12-week goal-setting intervention that uses a Fitbit watch (Fitbit Inc) and theoretically grounded SMS text messages to promote physical activity and sleep among Hispanic adolescents (aged between 14 and 16 years) with obesity. METHODS: After completing the intervention, a subsample of youth (N=15) participated in an in-depth interview. We categorized the themes into dimensions based on participant perspectives using the Practical, Robust Implementation, and Sustainability Model (PRISM) framework. RESULTS: Participants shared positive perceptions of wearing the Fitbit and receiving SMS text messages. Youth were highly engaged in monitoring their behaviors and perceived increased activity and sleep. Almost all youth organically received social support from a peer or family member and suggested the use of a group chat or team challenge for integrating peers into future interventions. However, most youth also expressed the need to take personal responsibility for the change in their behavior. Barriers that impacted the feasibility of the study included the skin-irritating material on the Fitbit watch band and environmental barriers (eg, lack of resources and school schedules), that limited participation in activity suggestions. Additionally, sync issues with the Fitbit limited the transmission of data, leading to inaccurate feedback. CONCLUSIONS: Fit24 is a promising approach for engaging Hispanic youth in a diabetes prevention program. Strategies are needed to address technical issues with the Fitbit and environmental issues such as message timing. While integrating peer social support may be desired by some, peer support strategies should be mindful of youth's desire to foster personal motivation for behavior change. Findings from this study will inform future diabetes prevention trials of Fit24 and other digital health interventions for high-risk pediatric populations.

microRNA 21 and long non-coding RNAs interplays underlie cancer pathophysiology: A narrative review.

Non-coding RNAs (ncRNAs) are a diverse group of functional RNA molecules that lack the ability to code for proteins. Despite missing this traditional role, ncRNAs have emerged as crucial regulators of various biological processes and have been implicated in the development and progression of many diseases, including cancer. MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are two prominent classes of ncRNAs that have emerged as key players in cancer pathophysiology. In particular, miR-21 has been reported to exhibit oncogenic roles in various forms of human cancer, including prostate, breast, lung, and colorectal cancer. In this context, miR-21 overexpression is closely associated with tumor proliferation, growth, invasion, angiogenesis, and chemoresistance, whereas miR-21 inactivation is linked to the regression of most tumor-related processes. Accordingly, miR-21 is a crucial modulator of various canonical oncogenic pathways such as PTEN/PI3K/Akt, Wnt/ß-catenin, STAT, p53, MMP2, and MMP9. Moreover, interplays between lncRNA and miRNA further complicate the regulatory mechanisms underlying tumor development and progression. In this regard, several lncRNAs have been found to interact with miR-21 and, by functioning as competitive endogenous RNAs (ceRNAs) or miRNA sponges, can modulate cancer tumorigenesis. This work presents and discusses recent findings highlighting the roles and pathophysiological implications of the miR-21-lncRNA regulatory axis in cancer occurrence, development, and progression. The data collected indicate that specific lncRNAs, such as MEG3, CASC2, and GAS5, are strongly associated with miR-21 in various types of cancer, including gastric, cervical, lung, and glioma. Indeed, these lncRNAs are well-known tumor suppressors and are commonly downregulated in different types of tumors. Conversely, by modulating various mechanisms and oncogenic signaling pathways, their overexpression has been linked with preventing tumor formation and development. This review highlights the significance of these regulatory pathways in cancer and their potential for use in cancer therapy as diagnostic and prognostic markers.
