    Abstract Background & aims: Chronic hepatitis B (CHB) disproportionately impacts foreign-born patients and those of Asian or Black race. Given the paucity of data, we aimed to study the impact of race and ethnicity on CHB patient characteristics and management.
    Methods: A retrospective analysis of adult CHB patients using data recorded in the deidentified Optum Clinformatics Data Mart Database (January 2003‒March 2021) was performed. We characterized and examined the rates of receiving adequate treatment evaluation (measuring hepatitis B virus DNA and alanine transaminase) and hepatitis B virus treatment among the racial and ethnic groups.
    Results: The study cohort included 42,140 patients: age, 51.9 ± 15.1 years; 56.1% male; 47% Asian; 26% White; 11% Black; and 7% Hispanic. Thirty-three percent of White and 48% of Asian patients had an annual household income greater than $100,000 US compared with 16% for Black and 25% for Hispanic patients (P < .001), with similar disparities in educational levels. Approximately one third of White (29.3%), Black (35.1%), and Hispanic (35.4%), and half of Asian (49.9%) patients received adequate evaluation (P < .001). Among patients who met American Association for the Study of Liver Diseases treatment criteria, treatment rates were similar among White (60.8%; P = .09) and Black (62.8%; P = .48), but lower among Hispanic (54.7%; P = .03), as compared with Asian patients (65.4%). On multivariable logistic regression adjusted for age, sex, provider type, viral co-infection, and fatty liver disease, Hispanic patients were less likely to receive treatment (adjusted hazard ratio, 0.69; 95% CI, 0.53‒0.91; P = .01) compared with Asian patients.
    Conclusions: Compared with Asian CHB patients, non-Asian patients were less likely to undergo adequate evaluation and Hispanic patients were less likely to receive treatment for CHB. Additional efforts are needed to improve CHB management, especially for non-Asian patients.

    Abstract Tamarillo fruit contains many phytochemicals that have beneficial therapeutic and nutritional properties. Spray-drying is widely used to preserve fruit puree in powder form. However, to obtain high-quality fruit powder, the optimisation of spray-drying conditions is necessary, as a high drying temperature can damage sensitive bioactive compounds. This study investigated the effects of spray-drying on the microstructure, polyphenolics, total flavonoids, total carotenoids, antioxidant activity, and anticancer capacity of tamarillo powder. Response surface methodology (RSM) was used to optimise the spray-drying process to produce tamarillo powder. The independent variables were inlet drying temperature (120-160 °C), flow rate (1-5 g/mL), and maltodextrin concentration (0-10%). These variables influenced the microstructural attributes, bioactive components, and cytotoxicity of the spray-dried tamarillo powder. The increase in polyphenols and antioxidant activities were favoured under high-temperature spray drying conditions and a low carrier concentration. The optimised spray-drying conditions for producing tamarillo powder with high antioxidant and anticancer activities, high yield, and stable bioactive compounds were found to be at 146.8 °C inlet temperature, and a flow rate of 1.76 g/mL.

    Abstract Enzymes, as a kind of biomacromolecules, play an important role in many physiological processes and relate directly to various diseases. Developing an efficient detection method for enzyme activity is important to achieve early diagnosis of enzyme-relevant diseases and high throughput screening of potential enzyme-relevant drugs. Time-resolved luminescence assay provide a high accuracy and signal-to-noise ratios detection methods for enzyme activity, which has been widely used in high throughput screening of enzyme-relevant drugs and diagnosis of enzyme-relevant diseases. Inspired by these advantages, various responsive probes based on metal complexes and metal-free organic compounds have been developed for time-resolved bioimaging and biosensing of enzyme activity owing to their long luminescence lifetimes, high quantum yields and photostability. In this review, we comprehensively reviewed metal complex- and metal-free organic compound-based responsive probes applied to detect enzyme activity through time-resolved imaging, including their design strategies and sensing principles. Current challenges and future prospects in this rapidly growing field are also discussed.

    Abstract Background & aim: Causes of hepatocellular carcinoma (HCC) may change as treatments become available for some liver diseases. We examined the distribution of HCC cause and survival of a nationwide cohort of insured patients.
    Methods: Optum's de-identified Clinformatics
    Results: A total of 34707 patients with HCC were included: mean age: 68.3±11.6 years, 61% male, 62% Caucasian, 74% cirrhosis. Non-alcoholic fatty liver disease (NAFLD) was the most common etiology (38.9%), then hepatitis C virus (HCV) (25.3%), cryptogenic (18.0%), alcohol-associated liver disease (9.4%), other liver diseases (5.8%) and hepatitis B virus (HBV) at 2.6%. NAFLD patients were the oldest (mean age 71.1±11.2) and had the highest Charlson Comorbidity Index (CCI) (mean 10.5±3.9), while HCV were the youngest (mean age 64.2±9.2 years) and HBV had the lowest CCI (mean 7.2±4.4) (both
    Conclusion: HCC patients in more recent time 2014-2021 were more likely to be older, more likely to have nonviral etiology, and had worse survival compared to those from 2003 to 2013.

    Abstract Diatom and pollen references such as atlases and identification keys are remarkably rare from the Gulf Coast region of the United States. This dataset describes modern and fossil diatom and pollen from Galveston Bay, Texas to Cedar Keys Florida, USA. An illustrated and descriptive atlas of diatom and pollen was compiled from original data to facilitate the identification of microfossil in sediments. For diatom atlas, we include light micrographs and detailed descriptions of a total of 32 diatom species, including 9 marine diatom species, 18 estuarine diatom species, and 5 freshwater diatom species. For pollen atlas, we include light micrographs and descriptions of a total of 28 pollen and non-pollen palynomorphs, including 3 mangrove taxa, 12 upland (tree and shrub) taxa, and 10 herbaceous taxa. The diatom atlas is referenced from LSU Global Change and Coastal Paleoecology Laboratory's light micrographs collection. The pollen and diatom datasets are associated with research articles by Yao et al. [1,2].

    Abstract It is important to understand the temporal trend of the paediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load to estimate the transmission potential of children in schools and communities. We determined the differences in SARS-CoV-2 viral load dynamics between nasopharyngeal samples of infected asymptomatic and symptomatic children. Serial cycle threshold values of SARS-CoV-2 from the nasopharynx of a cohort of infected children were collected for analysis. Among 17 infected children, 10 (58.8%) were symptomatic. Symptomatic children, when compared to asymptomatic children, had higher viral loads (mean cycle threshold on day 7 of illness 28.6 vs. 36.7, P = 0.02). Peak SARS-CoV-2 viral loads occurred around day 2 of illness in infected children. Although we were unable to directly demonstrate infectivity, the detection of significant amount of virus in the upper airway of asymptomatic children suggest that they have the potential to shed and transmit SARS-CoV-2. Our study highlights the importance of contact tracing and screening for SARS-CoV-2 in children with epidemiological risk factors regardless of their symptom status, in order to improve containment of the virus in the community, including educational settings.

    Abstract Background: Advanced practice providers (APP) may be able to play a role in improving the linkage to care in patients with chronic hepatitis B (CHB), but data are limited.
    Aim: To compare management of patients with CHB under APP-assisted versus physician-only care METHODS: This retrospective analysis identified patients with CHB infection from Optum's de-identified Clinformatics® Data Mart Database (2003-2021) using ICD-9/ICD-10 codes. We compared the proportion of patients with CHB who had adequate evaluation for treatment (defined as ALT, HBV DNA, ± HBeAg), and the proportion of treatment-eligible patients with CHB who received treatment between APP versus physician-only care.
    Results: We included 42,140 eligible patients (mean age: 51.9 ± 15.1; 56.1% male). Overall, 34.3% received APP care with increasing utilisation over time. Compared to physician-only care, patients who also received APP care were more likely to have viral co-infection, and more likely to have been seen by a specialist (72.1%). Overall, 62.8% and 56.2% of treatment-eligible patients based on AASLD and EASL guidelines, respectively, received treatment. APP care patients were more likely to be treated (AASLD adjusted HR: 1.18, 95%CI: 1.03-1.34; EASL adjusted HR:1.24, 95%CI: 1.09-1.41) after adjustment for age, sex, race/ethnicity, viral dual infection, baseline cirrhosis/liver cancer, number of HBV DNA and alanine aminotransferase measurements, and physician provider type.
    Conclusion: Treatment-eligible patients with CHB receiving APP care were more likely to receive antiviral therapy. APP care may help to expand the pool of providers for patients with CHB, and to improve current suboptimal treatment rates.
