ABSTRACT

Screening for viral hepatitis is considered a high-priority area in the Veterans Health Administration (VHA). Yet, few studies have examined viral hepatitis screening test use among low-income veterans who are considered high-risk with limited healthcare access. Using cross-sectional data from 933 participants in the 2021-2022 National Veteran Homeless and Other Poverty Experiences (NV-HOPE) study, we examined rates and correlates of lifetime screening for hepatitis B (HBV) and hepatitis C (HCV) infections. Multivariable logistic regression models evaluated characteristics associated with HBV/HCV screening. Nearly 16% and 21% reported lifetime HBV and HCV screening, respectively. These rates are considerably lower than HBV (47.3%) and HCV (92.9%) screening rates documented among contemporaneous veterans in VHA electronic health records. In the NV-HOPE data, veterans 50-79 years were more likely than those ≥80 years of age to ever-screen for HBV/HCV. Whereas, household income was inversely related to lifetime screening behaviours, veterans reporting 'other' employment types (vs. full-time/part-time employment) were more likely to ever-screen for HBV/HCV. Ever-screening for HBV was more likely among veterans reporting non-Hispanic 'other' (vs. non-Hispanic 'white') race, housing instability, Medicaid insurance, as well as drug use and cognitive disorder histories. Living with ≥5 members (vs. alone), histories of alcohol use, cancer, and liver disorders were also correlated with ever-screening for HCV. HIV/AIDS history correlated with ever-screening for HBV/HCV. In conclusion, fewer than one-third of low-income US veterans ever-screened for HBV/HCV, with lower screening rates among those less likely to be exposed to viral hepatitis, thereby informing interventions aimed at promoting available screening, treatment and vaccinations for HBV/HCV.

ABSTRACT

Background: Homeless-experienced veterans (HEVs) are an important but challenging group to care for in the U.S. Department of Veterans Affairs health care system, and there are opportunities to examine the potential of integrative and complementary medicine approaches. Methods: This observational study enrolled 33 HEVs in a one-group observational, prospective study of Battlefield Acupuncture (BFA) with a monthly follow-up for 3 months after initiating BFA. Results: Linear growth curve analyses revealed a significant improvement in overall pain scores and scores on the effects of pain on activity level, mood, and stress. Conclusions: These preliminary findings suggest the potential of BFA to improve pain among HEVs as an area for further research.

ABSTRACT

BACKGROUND: Nonalcoholic fatty pancreatitis (NAFP) presents a pressing challenge within the domain of metabolic disorders, necessitating further exploration to unveil its molecular intricacies and discover effective treatments. Our focus was to delve into the potential therapeutic impact of ZBiotic, a specially engineered strain of probiotic B. subtilis, in managing NAFP by targeting specific genes linked with necroptosis and the TNF signaling pathway, including TNF, ZBP1, HSPA1B, and MAPK3, along with their upstream epigenetic regulator, miR-5192, identified through bioinformatics. METHODS: Rats were subjected to either a standard or high-fat, high-sucrose diet (HFHS) for eight weeks. Subsequently, they were divided into groups: NAFP model, and two additional groups receiving daily doses of ZBiotic (0.5 ml and 1 ml/kg), and the original B. subtilis strain group (1 ml/kg) for four weeks, alongside the HFHS diet. RESULTS: ZBiotic exhibited remarkable efficacy in modulating gene expression, leading to the downregulation of miR-5192 and its target mRNAs (p < 0.001). Treatment resulted in the reversal of fibrosis, inflammation, and insulin resistance, evidenced by reductions in body weight, serum amylase, and lipase levels (p < 0.001), and decreased percentages of Caspase and Nuclear Factor Kappa-positive cells in pancreatic sections (p < 0.01). Notably, high-dose ZBiotic displayed superior efficacy compared to the original B. subtilis strain, highlighting its potential in mitigating NAFP progression by regulating pivotal pancreatic genes. CONCLUSION: ZBiotic holds promise in curbing NAFP advancement, curbing fibrosis and inflammation while alleviating metabolic and pathological irregularities observed in the NAFP animal model. This impact was intricately linked to the modulation of necroptosis/TNF-mediated pathway-related signatures.

ABSTRACT

Background Gastroesophageal reflux disease (GERD) is a global gastrointestinal disorder, and obesity is a particular risk factor. Symptoms of GERD, such as heartburn and acid reflux, are caused by abnormal relaxation in the lower esophagus, causing gastric acid reflux. Persistent symptoms can affect the patient's quality of life (QOL) and can cause complications, such as esophageal adenocarcinoma. Management of GERD includes lifestyle changes, antacids, and anti-reflux surgery. Even though GERD is a common disease, few research has been carried out on it in Saudi Arabia. Aim This study aimed to estimate the prevalence of GERD and its associated risk factors among obese individuals in the Al-Baha region population and the effect of GERD on their QOL. Methods A cross-sectional study included 314 obese participants from the Al-Baha region. A questionnaire was filled out to measure the prevalence of GERD, risk factors, and effects on the QOL of the participants. Data were analyzed by the IBM SPSS Statistics for Windows, version 26.0 (released 2019, IBM Corp., Armonk, NY). Descriptive statistics and the chi-squared test were applied. Logistic regression analysis was used to determine the factors associated with the incidence of GERD. A p-value of <0.05 was considered statistically significant. Results A total of 314 patients who met our inclusion criteria completed the survey; 42% of them were women, the mean age of all patients was 35.3 ± 12.9 years, and 38.2% of the patients were diagnosed with GERD. Epigastric pain and burning sensation were the most common symptoms (44.9%). Five out of six domains in the QOL questionnaire showed more effects among GERD participants than non-GERD participants, and the results were statistically significant (p = 0.001). Logistic regression analysis showed that men are 1.8 times more likely than women to be diagnosed with GERD, and smokers have 2.6 times the risk of being diagnosed with GERD than non-smokers. Conclusion The present study showed a high prevalence of GERD among obese patients in the Al-Baha region, negatively affecting their QOL. Major risk factors included gender, smoking, dyslipidemia, and hypertension. Public health programs to raise awareness of these risk factors and lifestyle habits are necessary to improve QOL and prevent complications.

ABSTRACT

The growing effects of climate change on Malaysia's coastal ecology heighten worries about air pollution, specifically caused by urbanization and industrial activity in the maritime sector. Trucks and vessels are particularly noteworthy for their substantial contribution to gas emissions, including nitrogen dioxide (NO2), which is the primary gas released in port areas. The application of advanced analysis techniques was spurred by the air pollution resulting from the combustion of fossil fuels such as fuel oil, natural gas and gasoline in vessels. The study utilized satellite photos captured by the Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel-5P satellite to evaluate the levels of NO2 gas pollution in Malaysia's port areas and exclusive economic zone. Before the COVID-19 pandemic, unrestricted gas emissions led to persistently high levels of NO2 in the analyzed areas. The temporary cessation of marine industry operations caused by the pandemic, along with the halting of vessels to prevent the spread of COVID-19, resulted in a noticeable decrease in NO2 gas pollution. In light of these favourable advancements, it is imperative to emphasize the need for continuous investigation and collaborative endeavours to further alleviate air contamination in Malaysian port regions, while simultaneously acknowledging the wider consequences of climate change on the coastal ecology. The study underscores the interdependence of air pollution, maritime activities and climate change. It emphasizes the need for comprehensive strategies that tackle both immediate environmental issues and the long-term sustainability and resilience of coastal ecosystems in the context of global climate challenges.

ABSTRACT

BACKGROUND: Homelessness and housing instability disproportionately affect U.S. veterans with psychiatric disorders, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), hepatitis C, and Alzheimer's disease and related disorders (ADRD). We examined housing status and/or HIV/AIDS in relation to ADRD risk and evaluated hepatitis C, substance use, and mental health disorders as mediators and/or moderators of hypothesized relationships, among U.S. veterans ≥50 years of age seeking Department of Veterans Affairs (VA) healthcare services. METHODS: A retrospective cohort study was conducted using linked VA Homeless Operations Management and Evaluation System and Corporate Data Warehouse databases (2017-2023) on 3 275 098 eligible veterans yielding 133 388 ADRD cases over 5 years of follow-up. Multivariable regression and causal mediation analyses were performed, controlling for demographic and clinical characteristics. RESULTS: Taking stably housed veterans without HIV/AIDS as referent, ADRD risk was higher among veterans with homelessness/housing instability alone (adjusted hazard ratio [aHR] = 1.67, 95% confidence interval [CI]: 1.63,1.72), lower among veterans with HIV/AIDS alone (aHR = 0.65, 95% CI: 0.58,0.73), but similar to veterans with homelessness/housing instability and HIV/AIDS (aHR = 1.01, 95% CI: 0.79,1.29). In adjusted models, hepatitis C and psychiatric disorders were positively related to homelessness/housing instability and ADRD risk, but negatively related to HIV/AIDS. Statistically significant mediation and/or moderation of hepatitis C and psychiatric disorders were observed, although <10% of total effects were explained by these characteristics, controlling for confounders. CONCLUSIONS: Among older veterans, ADRD diagnoses over 5 years were less among those with HIV/AIDS, but more among those with homelessness/housing instability, and these relationships were partly explained by hepatitis C and psychiatric disorders.

ABSTRACT

Mathematical manipulation technique has proven to be a very powerful tool for efficient processing and handling of highly overlapped spectra. This work introduced two green and sustainable approaches for the successful recovery of the ternary mixture, Tylosin tartarate (TYL), Sulfadimdine (SLD), and Trimethoprim (TRI). The approaches were constructed using three different methods, derivative ratio spectrum zero-crossing method (DRSZ), double divisor ratio spectra derivative method (DDRD), and factorized derivative ratio method coupled with spectrum subtraction (FDRM-SS). The two approaches succeeded in recovering the three drugs (Linearity range achieved were 0.5-5 µg/mL for TYL, 0.3-1.3 µg/mL for SLD, and 0.3-5 µg/mL for TRI), giving convenient standard deviations and satisfactory recovery percentages. The recommended methods have been verified in accordance with (ICH) guidelines. When the results were statistically compared to the official methods, no significant difference was found. Both AGREE-Analytical GREEnness Metric Approach and Software, and White Analytical Chemistry (WAC) RGB model gave scores of 0.93 and 97.2%, respectively, which proved that the approaches were eco-friendly and abiding by the sustainability principles.

ABSTRACT

The primary emphasis of this study was on the innovative and scientifically valuable hydrothermal synthesis of MIL-101(Co) as a metal-organic framework (MOF) material. Subsequently, the CuFe2O4 was incorporated into the MOF by a reduction-precipitation technique. The SrTiO3/CuFe2O4/MIL-101(Co) composite was synthesized by using hydrothermal in situ growth process. The XRD and FESEM investigations of the SrTiO3/CuFe2O4/MIL-101(Co) composite definitively verified its crystalline structure and proved its production with exact shape and dimensions. The data indicated that Candida albicans displayed the greatest vulnerability to all three produced materials, with reported Minimum Inhibitory Concentration (MIC) values of 500 µg mL-1 for MIL-101(Co). The CuFe2O4/MIL-101(Co) compound, when produced, exhibits MIC values of 200 µg mL-1. Additionally, the combination of CuFe2O4/MIL-101(Co) with SrTiO3, shows MIC values of 50 µg mL-1. The results also indicated that the MIC values for MIL-101(Co), and CuFe2O4/MIL-101(Co) against S. aureus were 100 µg mL-1. Ultimately, SrTiO3/CuFe2O4/MIL-101(Co) exhibited identical MIC values of 50 µg mL-1 against S. aureus. The concentration of the bacterial protein was increased by adding MIL-101(Co), CuFe2O4/MIL-101(Co), and SrTiO3/CuFe2O4/MIL-101(Co). The antibacterial capabilities of the SrTiO3/CuFe2O4/MIL-101(Co) were increased after being subjected to gamma doses of 100.0 kGy. This process paves a ways for manufacturing innovation in near future.

ABSTRACT

Background: Inflammation-mediated insulin resistance in type 2 diabetes mellitus (T2DM) increases complications, necessitating investigation of its mechanism to find new safe therapies. This study investigated the effect of rosavin on the autophagy and the cGAS-STING pathway-related signatures (ZBP1, STING1, DDX58, LC3B, TNF-α) and on their epigenetic modifiers (miR-1976 and lncRNA AC074117.2) that were identified from in silico analysis in T2DM animals. Methods: A T2DM rat model was established by combining a high-fat diet (HFD) and streptozotocin (STZ). After four weeks from T2DM induction, HFD/STZ-induced T2DM rats were subdivided into an untreated group (T2DM group) and three treated groups which received 10, 20, or 30 mg per kg of R. rosea daily for 4 weeks. Results: The study found that rosavin can affect the cGAS-STING pathway-related RNA signatures by decreasing the expressions of ZBP1, STING1, DDX58, and miR-1976 while increasing the lncRNA AC074117.2 level in the liver, kidney, and adipose tissues. Rosavin prevented further weight loss, reduced serum insulin and glucose, improved insulin resistance and the lipid panel, and mitigated liver and kidney damage compared to the untreated T2DM group. The treatment also resulted in reduced inflammation levels and improved autophagy manifested by decreased immunostaining of TNF-α and increased immunostaining of LC3B in the liver and kidneys of the treated T2DM rats. Conclusion: Rosavin has shown potential in attenuating T2DM, inhibiting inflammation in the liver and kidneys, and improving metabolic disturbances in a T2DM animal model. The observed effect was linked to the activation of autophagy and suppression of the cGAS-STING pathway.

ABSTRACT

Introduction: With the increasing prevalence of type 2 diabetes mellitus (T2DM), there is an urgent need to discover effective therapeutic targets for this complex condition. Coding and non-coding RNAs, with traditional biochemical parameters, have shown promise as viable targets for therapy. Machine learning (ML) techniques have emerged as powerful tools for predicting drug responses. Method: In this study, we developed an ML-based model to identify the most influential features for drug response in the treatment of type 2 diabetes using three medicinal plant-based drugs (Rosavin, Caffeic acid, and Isorhamnetin), and a probiotics drug (Z-biotic), at different doses. A hundred rats were randomly assigned to ten groups, including a normal group, a streptozotocin-induced diabetic group, and eight treated groups. Serum samples were collected for biochemical analysis, while liver tissues (L) and adipose tissues (A) underwent histopathological examination and molecular biomarker extraction using quantitative PCR. Utilizing five machine learning algorithms, we integrated 32 molecular features and 12 biochemical features to select the most predictive targets for each model and the combined model. Results and discussion: Our results indicated that high doses of the selected drugs effectively mitigated liver inflammation, reduced insulin resistance, and improved lipid profiles and renal function biomarkers. The machine learning model identified 13 molecular features, 10 biochemical features, and 20 combined features with an accuracy of 80% and AUC (0.894, 0.93, and 0.896), respectively. This study presents an ML model that accurately identifies effective therapeutic targets implicated in the molecular pathways associated with T2DM pathogenesis.

ABSTRACT

PURPOSE: The Veterans Health Administration (VHA) is the largest integrated healthcare system in the U.S. While preventive healthcare services are high priority in the VHA, low-income U.S. Veterans experience adverse life circumstances that may negatively impact their access to these services. This study examined lifetime prevalence as well as demographic, socioeconomic, military-specific, and clinical correlates of colorectal cancer (CRC) screening among low-income U.S. Veterans ≥ 50 years of age. METHODS: Cross-sectional data on 862 participants were analyzed from the 2021-2022 National Veteran Homeless and Other Poverty Experiences study. RESULTS: Overall, 55.3% (95% confidence interval [CI] 51.3-59.3%) reported ever-receiving CRC-screening services. In a multivariable logistic regression model, never-receivers of CRC screening were twice as likely to reside outside of the Northeast, and more likely to be married (odds ratio [OR] = 1.86, 95% CI 1.02, 3.37), have BMI < 25 kg/m2 [vs. 25- < 30 kg/m2] (OR = 1.75, 95% CI 1.19, 2.58), or ≥ 1 chronic condition (OR = 1.46, 95% CI 1.06, 2.02). Never-receivers of CRC screening were less likely to be female (OR = 0.53, 95% CI 0.29, 0.96), aged 65-79y [vs. ≥ 80y] (OR = 0.61, 95% CI 0.40, 0.92), live in 5 + member households (OR = 0.33, 95% CI 0.13, 0.86), disabled (OR = 0.45, 0.22, 0.92), with purchased health insurance (OR = 0.56, 95% CI 0.33, 0.98), or report alcohol-use disorder (OR = 0.10, 95% CI 0.02, 0.49) and/or HIV/AIDS (OR = 0.28, 95% CI 0.12, 0.68). CONCLUSION: Nearly 55% of low-income U.S. Veterans reported ever screening for CRC. Variations in CRC-screening behaviors according to veteran characteristics highlight potential disparities as well as opportunities for targeted behavioral interventions.

ABSTRACT

We investigated relations of depressive symptoms, antidepressant use, and epigenetic age acceleration with all-cause mortality risk among postmenopausal women. Data were analyzed from ≤1,900 participants in the Women's Health Initiative study testing four-way decomposition models. After a median 20.4y follow-up, 1,161 deaths occurred. Approximately 11% had elevated depressive symptoms (EDS+), 7% were taking antidepressant medication at baseline (ANTIDEP+), while 16.5% fell into either category (EDS_ANTIDEP+). Baseline ANTIDEP+, longitudinal transition into ANTIDEP+ and accelerated epigenetic aging directly predicted increased mortality risk. GrimAge DNA methylation age acceleration (AgeAccelGrim) partially mediated total effects of baseline ANTIDEP+ and EDS_ANTIDEP+ on all-cause mortality risk in socio-demographic factors-adjusted models (Pure Indirect Effect >0, P < 0.05; Total Effect >0, P < 0.05). Thus, higher AgeAccelGrim partially explained the relationship between antidepressant use and increased all-cause mortality risk, though only prior to controlling for lifestyle and health-related factors. Antidepressant use and epigenetic age acceleration independently predicted increased all-cause mortality risk. Further studies are needed in varying populations.

ABSTRACT

BACKGROUND: The study examined how plasma proteome indicators may explain the link between poor cardiovascular health (CVH) and dementia risk. METHODS: The present study involved 28,974 UK Biobank participants aged 50-74y at baseline (2006-2010) who were followed-up for ≤ 15 y for incidence of dementia. CVH was calculated using Life's Essential 8 (LE8) total scores. The scores were standardized and reverse coded to reflect poor CVH (LE8z_rev). OLINK proteomics was available on this sample (k = 1,463 plasma proteins). The study primarily tested the mediating effects of the plasma proteome in LE8z_rev-dementia effect. The total effect was decomposed into "mediation only" or pure indirect effect (PIE), "interaction only" or interaction referent (INTREF), "neither mediation nor interaction" or controlled direct effect (CDE), and "both mediation and interaction" or mediated interaction (INTMED). RESULTS: The study found poorer CVH assessed by LE8z_rev increased the risk of all-cause dementia by 11 % [per 1 SD, hazard ratio, (HR) = 1.11, 95 % CI: 1.03-1.20, p = 0.005). The study identified 11 plasma proteins with strong mediating effects, with GDF15 having the strongest association with dementia risk (per 1 SD, HR = 1.24, 95 % CI: 1.16, 1.33, P < 0.001 when LE8z_rev is set at its mean value) and the largest proportion mediated combining PIE and INTMED (62.6 %; 48 % of TE is PIE), followed by adrenomedullin or ADM. A first principal component with 10 top mediators (TNFRSF1A, GDF15, FSTL3, COL6A3, PLAUR, ADM, GFRAL, ACVRL1, TNFRSF6B, TGFA) mediated 53.6 % of the LE8z_rev-dementia effect. Using all the significant PIE (k = 526) proteins, we used OLINK Insight pathway analysis to identify key pathways, which revealed the involvement of the immune system, signal transduction, metabolism, disease, protein metabolism, hemostasis, membrane trafficking, extracellular matrix organization, developmental biology, and gene expression among others. STRING analysis revealed that five top consistent proteomic mediators were represented in two larger clusters reflecting numerous interconnected biological gene ontology pathways, most notably cytokine-mediated signaling pathway for GDF15 cluster (GO:0019221) and regulation of peptidyl-tyrosine phosphorylation for the ADM cluster (GO:0050730). CONCLUSION: Dementia is linked to poor CVH mediated by GDF15 and ADM among several key proteomic markers which collectively explained âˆ¼ 54 % of the total effect.

ABSTRACT

The hazard of diseases created by S. Enteritidis and S. Typhimurium is relatively high in turkey meat products. Combinations of preservation methods are utilized in many strategies, such as mild heat with decreased water activity, a changed atmosphere, refrigerated storage, and decreased heat treatment with some acidification. Within the domain of ready-to-eat food technology, a range of preservation methods are typically utilized to enhance shelf life, such as applying mild heat in tandem with reduced water activity, employing modified atmosphere packaging, utilizing refrigerated storage, and utilizing reduced heat treatment combined with acidification. This investigation aimed to determine how S. Enteritidis and S. Typhimurium grew when sliced ready-to-eat smoked turkey (RTE-SM) was stored at 0, 5, 10, and 15°C for various periods. The study also examined the effects of modified atmosphere packaging (MAP) (40% CO2 and 60% N2) and VP on these growth patterns. Total viable count (TVC), lactic acid bacteria (LAB), pH, and redox potential levels were determined. The control experiment on RTE-SM showed no Salmonella growth within 30 d of storage at any temperature. This indicated that the RTE-SM in use did not initially contain S. Typhimurium and S. Enteritidis. Results indicated that the storage of RTE-SM using a combination of VP, MAP, and MAPEO with storage at 0 and 5°C did not allow for the pathogen to grow throughout storage. In comparison, at 10 and 15°C after one day, which allowed for minor growth (0.17-0.5 log CFU/g)? In contrast, at 0 and 5°C, Salmonella survives until the end of storage (173 d). However, the combination of MAPEO with the same storage temperatures achieved the elimination of the pathogen in the meat after 80 d. The combination of both packaging systems with high temperatures (10 or 15°C) allowed for the multiplication and growth of the bacterium through the product's shelf life of more than 1 log CFU/g. Thus, a combination of MAP or MAPEO with low storage temperatures (0 or 5°C) inhibited the growth of the pathogen.

ABSTRACT

Neurofilament light chain (NfL) is a neuron-specific structural protein released into the extracellular space, including body fluids, upon neuroaxonal damage. Despite evidence of a link in neurological disorders, few studies have examined the association of serum NfL with mortality in population-based studies. Data from the National Health and Nutrition Survey were utilized including 2,071 Non-Hispanic White, Non-Hispanic Black and Hispanic adult participants and adult participants of other ethnic groups (20-85 years) with serum NfL measurements who were followed for ≤ 6 years till 2019. We tested the association of serum NfL with mortality in the overall population and stratified by sex with the addition of potential interactive and mediating effects of cardio-metabolic risk factors and nutritional biomarkers. Elevated serum NfL levels (above median group) were associated with mortality risk compared to the below median NfL group in the overall sample (P = 0.010), with trends observed within each sex group (P < 0.10). When examining Loge NfL as a continuum, one standard deviation of Loge NfL was associated with an increased mortality risk (HR = 1.88, 95% CI 1.60-2.20, P < 0.001) in the reduced model adjusted for age, sex, race, and poverty income ratio; a finding only slightly attenuated with the adjustment of lifestyle and health-related factors. Four-way decomposition indicated that there was, among others, mediated interaction between NfL and HbA1c and a pure inconsistent mediation with 25(OH)D3 in predicting all-cause mortality, in models adjusted for all other covariates. Furthermore, urinary albumin-to-creatinine ratio interacted synergistically with NfL in relation to mortality risk both on the additive and multiplicative scales. These data indicate that elevated serum NfL levels were associated with all-cause mortality in a nationally representative sample of US adults.

ABSTRACT

OBJECTIVES: Opioid use disorder (OUD) is characterized as a chronic condition that was first outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and now the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision. It encompasses frequent opioid usage, cravings, the development of tolerance, withdrawal symptoms upon discontinuation, unsuccessful attempts to quit or reduce use, and recurrent use even when faced with negative consequences. Both national- and state-level data show that overdose deaths associated with prescription opioids are increasing at an alarming rate. The increasing overdose deaths from illicitly manufactured fentanyl and other synthetic opioids compound this epidemic's burden. The present study sought to determine the prevalence and potential factors associated with OUD in North Carolina. METHODS: Using the State Inpatient Database, a retrospective cross-sectional study was conducted to identify OUD-related discharges between 2000 and 2020. Descriptive statistics and rates of OUD per 1000 discharges were calculated. Simple and multivariable logistic regression models were used to identify factors associated with increased odds of having an opioid use disorder diagnosis at discharge. The deviance-Pearson goodness of fit statistic was also used. Variables were identified using International Classification of Diseases, Ninth Revision, Clinical Modification, and International Classification of Diseases, Tenth Revision, Clinical Modification, codes in the discharge records. RESULTS: Of 19,370,483 hospitalizations that occurred between 2000 and 2020 in North Carolina, 483,250 were associated with OUD, a prevalence rate of 24.9 cases per 1000 discharges. The highest OUD rates were seen among adults who self-paid for their hospitalization, those with Medicaid, and those with other types of payors such as Workers' Compensation and the Indian Health Service; individuals between 25 and 54 years old; tobacco and alcohol users; Native American patients; patients located in urban areas; patients with lower household income; White patients; and female patients. OUD also was associated with increased odds of having one or more comorbid psychiatric disorders when controlling for other factors. CONCLUSIONS: Although preventive measures are crucial, including policies that discourage prescribing opioids for noncancer pain and those that target the manufacturing and distribution of synthetic opioids, providing integrated care for patients with OUD and co-occurring psychiatric and/or physical disorders is equally important. These findings suggest the need for a system-wide public health response focused on the expansion of primary prevention and treatment efforts, including crisis services, harm reduction services, and recovery programs.

ABSTRACT

Background: Loneliness, dementia, and mortality are interconnected. Objective: We aimed at understanding mediating pathways and interactions between loneliness and dementia in relation to mortality risk. Methods: The study tested bi-directional relationships between dementia, loneliness, and mortality, by examining both interactions and mediating effects in a large sample of older US adults participating in the nationally representative Health and Retirement Study. Out of≤6,468 older participants selected in 2010, with mean baseline age of 78.3 years and a follow-up time up to the end of 2020, 3,298 died at a rate of 64 per 1,000 person-years (P-Y). Cox proportional hazards and four-way decomposition models were used. Results: Algorithmically defined dementia status (yes versus no) was consistently linked with a more than two-fold increase in mortality risk. Dementia status and Ln(odds of dementia) were strongly related with mortality risk across tertiles of loneliness score. Loneliness z-score was also linked to an elevated risk of all-cause mortality regardless of age, sex, or race or ethnicity, and its total effect (TE) on mortality was partially mediated by Ln(odds of dementia), z-scored, (≤40% of the TE was a pure indirect effect). Conversely, a small proportion (<5%) of the TE of Ln(odds of dementia), z-scored, on mortality risk was explained by the loneliness z-score. Conclusions: In sum, dementia was positively associated with all-cause mortality risk, in similar fashion across loneliness score tertiles, while loneliness was associated with mortality risk. TE of loneliness on mortality risk was partially mediated by dementia odds in reduced models.

ABSTRACT

The plasma proteome can mediate poor oral health problems (POHP)'s link to incident dementia. We screened 37,269 UK Biobank participants 50-74 years old (2006-2010) for prevalent POHP, further tested against 1463 plasma proteins and incident dementia over up to 15 years of follow-up. Total effect (TE) of POHP-dementia through plasma proteomic markers was decomposed into pure indirect effect (PIE), interaction referent (INTREF), controlled direct effect (CDE), or mediated interaction (INTMED). POHP increased the risk of all-cause dementia by 17% (P < 0.05). Growth differentiation factor 15 (GDF15) exhibited the strongest mediating effects (PIE > 0, P < 0.001), explaining 28% the total effect of POHP on dementia, as a pure indirect effect. A first principal component encompassing top 4 mediators (GDF15, IL19, MMP12, and ACVRL1), explained 11% of the POHP-dementia effect as a pure indirect effect. Pathway analysis including all mediators (k = 173 plasma proteins) revealed the involvement of the immune system, signal transduction, metabolism, disease, and gene expression, while STRING analysis indicated that top mediators within the first principal component were also represented in the two largest proteomic clusters. The dominant biological GO pathway for the GDF15 cluster was GO:0007169 labeled as "transmembrane receptor protein tyrosine kinase signaling pathway." Dementia is linked to POHP mediated by GDF15 among several proteomic markers.

ABSTRACT

Crucial to the Earth's oceans, ocean currents dynamically react to various factors, including rotation, wind patterns, temperature fluctuations, alterations in salinity and the gravitational pull of the moon. Climate change impacts coastal ecosystems, emphasizing the need for understanding these currents. This study explores multibeam echosounder (MBES), specifically R2-Sonic 2020 instrument, offering detailed seabed information. Investigating coral reefs, rocky reefs and artificial reefs aimed to map seafloor currents movement and their climate change responses. MBES data viz. Bathymetry and backscatter were classified and acoustic doppler current profiler (ADCP) ground data were validated using random forest regression. Results indicated high precision in currents speed measurement i.e. coral reefs with 0.96, artificial reefs with 0.94 and rocky reefs with 0.97. Currents direction accuracy was notable in coral reefs with 0.85, slightly lower in rocky reefs with 0.72 and artificial reefs with 0.60. Random forest identified sediment and backscatter as key for speed prediction while direction relies on bathymetry, slope and aspect. The study emphasizes integrating sediment size, backscatter, bathymetry and ADCP data for seafloor current analysis. This multibeam data on sediments and currents support better marine spatial planning and determine biodiversity patterns planning in the reef area.

ABSTRACT

Pathways explaining racial/ethnic and socio-economic status (SES) disparities in white matter integrity (WMI) reflecting brain health, remain underexplored, particularly in the UK population. We examined racial/ethnic and SES disparities in diffusion tensor brain magnetic resonance imaging (dMRI) markers, namely global and tract-specific mean fractional anisotropy (FA), and tested total, direct and indirect effects through lifestyle, health-related and cognition factors using a structural equations modeling approach among 36,184 UK Biobank participants aged 40-70 y at baseline assessment (47% men). Multiple linear regression models were conducted, testing independent associations of race/ethnicity, socio-economic and other downstream factors in relation to global mean FA, while stratifying by Alzheimer's Disease polygenic Risk Score (AD PRS) tertiles. Race (Non-White vs. White) and lower SES predicted poorer WMI (i.e. lower global mean FA) at follow-up, with racial/ethnic disparities in FAmean involving multiple pathways and SES playing a central role in those pathways. Mediational patterns differed across tract-specific FA outcomes, with SES-FAmean total effect being partially mediated (41% of total effect = indirect effect). Furthermore, the association of poor cognition with FAmean was markedly stronger in the two uppermost AD PRS tertiles compared to the lower tertile (T2 and T3: ß±SE: -0.0009 ± 0.0001 vs. T1: ß±SE: -0.0005 ± 0.0001, P < 0.001), independently of potentially confounding factors. Race and lower SES were generally important determinants of adverse WMI outcomes, with partial mediation of socio-economic disparities in global mean FA through lifestyle, health-related and cognition factors. The association of poor cognition with lower global mean FA was stronger at higher AD polygenic risk.
