Objective: There is a lack of controlled studies of community-wide interventions to increase screening for hepatitis B (HBV) among Asian Americans, particularly Vietnamese Americans, who disproportionately suffer from HBV-related illnesses. The objective of our study was to develop, implement, and evaluate the effectiveness of a media campaign to promote HBV screening among Vietnamese Americans.Design: We designed and implemented a three-year media campaign promoting HBV screening among Vietnamese Americans. Evaluation consisted of cross-sectional pre- and post-intervention population-based telephone surveys of Vietnamese Americans adults age 18-64 who spoke English or Vietnamese and lived in the Northern California (intervention) or Greater Washington, D.C. (comparison) communities in 2007 or 2011. Statistical analysis was completed in 2012. The main outcome was self-report of HBV testing, defined as participants answering 'Yes' to the question: 'Have you ever had a blood test to check for hepatitis B?'Results: The sample sizes at pre- and post-intervention were 1,704 and 1,666, respectively. Both communities reported increased exposure to HBV-related booklets, radio and television advertisements, and websites. Only the intervention community reported increased exposure to newspaper elements. HBV screening increased in both communities (intervention: 65.3% to 73.1%, p

Mathematics - Group Theory - Abstract
In 2014, Benjamin Nachman showed that when $p\equiv$1 mod 8, the 2-dimensional projective linear group over the field of $p$ elements fails the replacement property if the maximal length $m$ of an irredundant generating sequence for the group is 3. In addition, if $m=4$, the group satisfies the property for any prime $p$. In this paper, we will extend such classification for PSL$(2,q)$ where $q$ is $p$ and $p^2$ with conditions of modulo 8 and 10 on $p$.

Culture impacts help-seeking preferences. We examined Vietnamese Americans' help-seeking preferences for depressive symptoms, through a telephone survey (N = 1666). A vignette describing an age- and gender-matched individual with depression was presented, and respondents chose from a list of options and provided open-ended responses about their help-seeking preferences. Results showed that 78.3% would seek professional help, either from a family doctor, a mental health provider, or both; 54.4% preferred to seek help from a family doctor but not from a mental health provider. Most (82.1%) would prefer to talk to family or friends, 62.2% would prefer to look up information, and 50.1% would prefer to get spiritual help. Logistic regression analysis revealed that preferences for non-professional help-seeking options (such as talking to friends or family, looking up information, and getting spiritual help), health care access, and perceived poor health, were associated with increased odds of preferring professional help-seeking. This population-based study of Vietnamese Americans highlight promising channels to deliver education about depression and effective help-seeking resources, particularly the importance of family doctors and social networks. Furthermore, addressing barriers in access to care remains a critical component of promoting professional help-seeking.

BackgroundColorectal cancer (CRC) is the second most commonly diagnosed cancer among Korean American men and women. Although CRC screening is effective in reducing the burden of this disease, studies have shown that Korean Americans have low screening rates.MethodsThe authors conducted a 2-arm cluster randomized controlled trial comparing a brochure (print) with a brochure and lay health educator (LHE) outreach (print + LHE) in increasing CRC screening rates among Korean American individuals. Self-administered written surveys at baseline and at 6 months assessed knowledge of CRC and its screening, ever screening, and being up to date with screening.ResultsA total of 28 LHEs recruited 348 participants aged 50 to 75 years from their social networks. Significant percentages of participants reported not having health insurance (29.3%) or a usual source of care (35.6%). At 6 months postintervention, the print + LHE participants had a greater increase in knowledge compared with those in the print arm (P = .0013). In multivariable analyses, both groups had significant increases in ever screening (print plus LHE: odds ratio [OR], 1.60 [95% confidence interval (95% CI), 1.26-2.03] and print: OR, 1.42 [95% CI, 1.10-1.82]) and being up to date with screening (print plus LHE: OR, 1.63 [95% CI, 1.23-2.16] and print: OR, 1.40 [95% CI, 1.04-1.89]). However, these increases did not differ significantly between the study arms. Having insurance and having seen a provider within the past year were found to be positively associated with screening.ConclusionsCompared with a brochure, LHE outreach yielded greater increases in knowledge but resulted in similar increases in CRC screening in a Korean American population with barriers to health care access. More work is needed to appropriately address logistical and system barriers in this community. Cancer 2017;123:2705-15. © 2017 American Cancer Society.

BackgroundAsian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans.MethodsA cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months.ResultsAll 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes.ConclusionsA culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy.

Background Safety and immunogenicity of 3 doses of BNT162b2 and CoronaVac in adult and pediatric patients with inborn errors of immunity (IEIs) remain unknown. Intradermal vaccination may improve immunogenicity in immunocompromised patients. Our study (NCT04800133) aimed to determine the safety and immunogenicity in patients with IEIs receiving a 3-dose primary series of mRNA vaccine BNT162b2 (age 12+) or inactivated whole-virion vaccine CoronaVac (age 3+) in Hong Kong, including Omicron BA.1 neutralization, in a nonrandomized manner. Intradermal vaccination was also studied. Methods Thirty-nine patients were vaccinated, including 16 with homologous intramuscular 0.3ml BNT162b2 and 17 with homologous intramuscular 0.5ml CoronaVac. Two patients received 3 doses of intradermal 0.5ml CoronaVac, and 4 patients received 2 doses of intramuscular BNT162b2 and the third dose with intradermal BNT162b2. Adverse reactions and adverse events were tracked for 7 and 28 days after each dose. Antibody responses assessed included binding IgG antibody to wild-type (WT) spike receptor-binding domain (S-RBD IgG) and surrogate neutralization activity to WT and BA.1 viruses. T cell responses were examined by intracellular cytokine staining following stimulation with SARS-CoV-2 peptide pool(s). Results No safety concerns were identified. Inadequate antibody responses were found after 2 doses in patients with humoral immunodeficiencies and especially so against BA.1. Dose 3 of either vaccine increased S-RBD IgG response. T cell responses against SARS-CoV-2 antigens were detected in vaccinated IEI patients. Intradermal third dose vaccine led to high antibody response in 4 patients. Conclusions The primary vaccination series of BNT162b2 and CoronaVac in adults and children with IEIs should include 3 doses for optimal immunogenicity.

- Abstract
Objective: There is a lack of controlled studies of community-wide interventions to increase screening for hepatitis B (HBV) among Asian Americans, particularly Vietnamese Americans, who disproportionately suffer from HBV-related illnesses. The objective of our study was to develop, implement, and evaluate the effectiveness of a media campaign to promote HBV screening among Vietnamese Americans.Design: We designed and implemented a three-year media campaign promoting HBV screening among Vietnamese Americans. Evaluation consisted of cross-sectional pre- and post-intervention population-based telephone surveys of Vietnamese Americans adults age 18-64 who spoke English or Vietnamese and lived in the Northern California (intervention) or Greater Washington, D.C. (comparison) communities in 2007 or 2011. Statistical analysis was completed in 2012. The main outcome was self-report of HBV testing, defined as participants answering Yes to the question: Have you ever had a blood test to check for hepatitis B?Results: The sample sizes at pre- and post-intervention were 1,704 and 1,666, respectively. Both communities reported increased exposure to HBV-related booklets, radio and television advertisements, and websites. Only the intervention community reported increased exposure to newspaper elements. HBV screening increased in both communities (intervention: 65.3% to 73.1%, p < 0.01, comparison: 57.7% to 66.0%, p < 0.01). In multivariable analyses, there was no intervention effect. In both communities, exposure to media elements (Odds Ratio 1.26 [95% Confidence Interval: 1.21, 1.31] for each additional element) was significantly associated with screening.Conclusions: Among Vietnamese Americans in 2 large communities, HBV screening rates were sub-optimal. Screening increased in both the intensive media intervention and comparison communities, and exposure to HBV-related media messages was associated with increased screening.

- Abstract
BACKGROUND: In Australia, Chinese migrants are among the populations most affected by hepatitis B virus (HBV) infection but often experience late diagnosis or access to clinical care. This study aims to explore approaches to increase HBV testing in Australia's Chinese community and inform evaluation planning, specifically to i) assess the feasibility and acceptability of HBV educational programs, and ii) compare HBV testing uptake in people receiving a tailored education resource focussing on liver cancer prevention compared with a standard HBV education package. METHODS: This is a pre-post mixed-methods pilot and feasibility study. People of Chinese ethnicity and unsure of their HBV infection or immunity status were recruited from ten community sites in Melbourne, Australia in 2019-2020. Participants were randomised to receive an education package (comprised of a leaflet and in-person one-on-one educational session) with a focus on either 1) standard HBV-related information, or 2) liver cancer prevention. Participants completed a baseline questionnaire prior to receiving the intervention and were followed up at 6 months' time for a questionnaire and an opt-in semi-structured interview. Primary study outcomes included feasibility of study procedures, measured by recruitment, participation, and retention rates; acceptability of the education program assessed by acceptability scores; and HBV testing uptake rate in each arm. Secondary outcomes include HBV-related knowledge change, assessed by pre-post comparison; and factors affecting participants' testing behaviour analysed using qualitative data. RESULTS: Fifty-four participants received an education package; baseline and follow-up data from 33 (61%) were available. The study procedures of recruitment and retention were feasible; the acceptability of the education program was moderate with improved HBV-related knowledge observed. Four participants self-reported being tested: one (1/15, 7%) in the standard HBV informa

IMPORTANCE: Comprehensive and timely monitoring of disease burden in all age groups, including children and adolescents, is essential for improving population health. OBJECTIVE: To quantify and describe levels and trends of mortality and nonfatal health outcomes among children and adolescents from 1990 to 2015 to provide a framework for policy discussion. EVIDENCE REVIEW: Cause-specific mortality and nonfatal health outcomes were analyzed for 195 countries and territories by age group, sex, and year from 1990 to 2015 using standardized approaches for data processing and statistical modeling, with subsequent analysis of the findings to describe levels and trends across geography and time among children and adolescents 19 years or younger. A composite indicator of income, education, and fertility was developed (Socio-demographic Index [SDI]) for each geographic unit and year, which evaluates the historical association between SDI and health loss. FINDINGS: Global child and adolescent mortality decreased from 14.18 million (95% uncertainty interval [UI], 14.09 million to 14.28 million) deaths in 1990 to 7.26 million (95% UI, 7.14 million to 7.39 million) deaths in 2015, but progress has been unevenly distributed. Countries with a lower SDI had a larger proportion of mortality burden (75%) in 2015 than was the case in 1990 (61%). Most deaths in 2015 occurred in South Asia and sub-Saharan Africa. Global trends were driven by reductions in mortality owing to infectious, nutritional, and neonatal disorders, which in the aggregate led to a relative increase in the importance of noncommunicable diseases and injuries in explaining global disease burden. The absolute burden of disability in children and adolescents increased 4.3% (95% UI, 3.1%-5.6%) from 1990 to 2015, with much of the increase owing to population growth and improved survival for children and adolescents to older ages. Other than infectious conditions, many top causes of disability are associated with long-term sequelae of conditions present at birth (eg, neonatal disorders, congenital birth defects, and hemoglobinopathies) and complications of a variety of infections and nutritional deficiencies. Anemia, developmental intellectual disability, hearing loss, epilepsy, and vision loss are important contributors to childhood disability that can arise from multiple causes. Maternal and reproductive health remains a key cause of disease burden in adolescent females, especially in lower-SDI countries. In low-SDI countries, mortality is the primary driver of health loss for children and adolescents, whereas disability predominates in higher-SDI locations; the specific pattern of epidemiological transition varies across diseases and injuries. CONCLUSIONS AND RELEVANCE: Consistent international attention and investment have led to sustained improvements in causes of health loss among children and adolescents in many countries, although progress has been uneven. The persistence of infectious diseases in some countries, coupled with ongoing epidemiologic transition to injuries and noncommunicable diseases, require all countries to carefully evaluate and implement appropriate strategies to maximize the health of their children and adolescents and for the international community to carefully consider which elements of child and adolescent health should be monitored.

Asian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans.A cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months.All 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P.0001). In multivariable regression analyses, the intervention group demonstrated a greater increase than the control group in reporting ever-screening (adjusted odds ratio, 1.73; 95% confidence interval, 1.07-2.79) and being up-to-date with screening (adjusted odds ratio, 1.71; 95% confidence interval, 1.26-2.32). Individuals who had health insurance were found to have4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes.A culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy.

Background: p75ECD-Fc is a recombinant human protein that has recently been developed as a novel therapy for Alzheimer’s disease. Current studies showed that it is able to alleviate Alzheimer’s disease pathologies in animal models of dementia. Thus, knowledge about the pharmacokinetic behavior and tissue distribution of this novel protein is crucial in order to better understand its pharmacodynamics and more importantly for its clinical development. Methods: The aim of this study is to characterize the pharmacokinetics of p75ECD-Fc after single intravenous and subcutaneous injection of 3mg/kg in Sprague Dawley rats. We calculated the bioavailability of the SC route and studied the distribution of that protein in different tissues, cerebrospinal fluid and urine using ELISA and immunofluorescence techniques. In-vitro stability of the drug was also assessed. Data obtained were analyzed with Non-compartmental pharmacokinetic method using R. Results: Results showed that the bioavailability of SC route was 66.15%. Half-life time was 7.5 ± 1.7 and 6.2 ± 2.4 days for IV and SC injection, respectively. Tissue distribution of p75ECD-Fc was modest with the ability to penetrate the blood brain barrier. It showed high in vitro stability in human plasma. Conclusion: These acceptable pharmacokinetic properties of p75ECD-Fc present it as a potential candidate for clinical development for the treatment of Alzheimer’s disease.

- Abstract
Lung cancer is a severe challenge to the health care system with intrinsic resistance to first and second-line chemo/radiotherapies. In view of the sterile environment of lung cancer, several immunotherapeutic drugs including nivolumab, pembrolizumab, atezolizumab, and durvalumab are currently being used in clinics globally with the intention of releasing exhausted T-cells back against refractory tumor cells. Immunotherapies have a limited response rate and may cause immune-related adverse events (irAEs) in some patients. Hence, a deeper understanding of regulating immune checkpoint interactions could significantly enhance lung cancer treatments. In this review, we explore the role of miRNAs in modulating immunogenic responses against tumors. We discuss various aspects of how manipulating these checkpoints can bias the immune system's response against lung cancer. Specifically, we examine how altering the miRNA profile can impact the activity of various immune checkpoint inhibitors, focusing on the PD-1/PD-L1 pathway within the complex landscape of lung cancer. We believe that a clear understanding of the host's miRNA profile can influence the efficacy of checkpoint inhibitors and significantly contribute to existing immunotherapies for lung cancer patients. Additionally, we discuss ongoing clinical trials involving immunotherapeutic drugs, both as standalone treatments and in combination with other therapies, intending to advance the development of immunotherapy for lung cancer., (© 2024.

- Abstract
The mortality and hospitalization rate by COVID-19 dropped significantly currently, but its seasonal outbreaks make antiviral treatment still vital. The mortality and hospitazation rate by COVID-19 dropped significantly currently, but its seasonal ourbreaks make antiviral treatment still vital. In our study, syrian golden hamsters were treated with molnupiravir and interferons (IFNs) after SARS-CoV-2 infection. Their weight changes, pathological changes, virus replication and inflammation levels were evaluated. In the IFNs single treatment, only IFN-α group reduced viral load (p < 0.05) and virus titer in hamster lungs. The TNF-α expression decreased significantly in both IFNs treatment at 2dpi. Histological and immunofluorescence results showed lung damage in the IFNs groups were milder at 4dpi. In the molnupiravir/IFN-α combination treatment, weight loss and virus replication in lung were significantly decreased in the mono-molnupiravir group and combination group (p < 0.05), the expression of IL-6, TNF-α, IL-1β and MIP-1α also decreased significantly (p < 0.05), but the combination treatment was not more effective than the mono-molnupiravir treatment. Histological and immunofluorescence results showed the lung damage and inflammation in mono-molnupiravir and combination groups were milder. In summary, IFNs treatment had anti-inflammatory effect against SARS-CoV-2, only IFN-α showed a weak antiviral effect. Molnupiravir/IFN-α combination treatment was effective against SARS-CoV-2 but was not superior to mono-molnupiravir treatment. IFN-α could be considered for immunocompromised patients to stimulate and activate early immune responses., (© 2024 Wiley Periodicals LLC.)

- Abstract
Cell cycle dysregulation is a hallmark of cancer that promotes eccessive cell division. Cyclin-dependent kinase 4 (CDK4) and cyclin-dependent kinase 6 (CDK6) are key molecules in the G1-to-S phase cell cycle transition and are crucial for the onset, survival, and progression of breast cancer (BC). Small-molecule CDK4/CDK6 inhibitors (CDK4/6i) block phosphorylation of tumor suppressor Rb and thus restrain susceptible BC cells in G1 phase. Three CDK4/6i are approved for the first-line treatment of patients with advanced/metastatic hormone receptor-positive (HR
+ )/human epidermal growth factor receptor 2-negative (HER2- ) BC in combination with endocrine therapy (ET). Though this has improved the clinical outcomes for survival of BC patients, there is no established standard next-line treatment to tackle drug resistance. Recent studies suggest that CDK4/6i can modulate other distinct effects in both BC and breast stromal compartments, which may provide new insights into aspects of their clinical activity. This review describes the biochemistry of the CDK4/6-Rb-E2F pathway in HR+ BC, then discusses how CDK4/6i can trigger other effects in BC/breast stromal compartments, and finally outlines the mechanisms of CDK4/6i resistance that have emerged in recent preclinical studies and clinical cohorts, emphasizing the impact of these findings on novel therapeutic opportunities in BC., Competing Interests: Declaration of Competing Interest S.A.W.: Consulting/Advisory Board: Foundation Medicine, Eli Lilly, Novartis, Astrazeneca, Biovica, Hologic, Pfizer, Puma Biotechnology; Education/Speaking: Guardant Health, Eli Lilly, 2ndMD; Institutional Research Support: Genentech, Eli Lilly, Pfizer, Pfizer, Nuvation Bio, Regor Therapeutics.

- Abstract
Background: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has lasted for three years. Coinfection with seasonal influenza may occur resulting in more severe diseases. The interaction between these two viruses for infection and the effect of antiviral treatment remains unclear., Methods: A SARS-CoV-2 and influenza H1N1 coinfection model on Calu-3 cell line was established, upon which the simultaneous and sequential coinfection was evaluated by comparing the viral load. The efficacy of molnupiravir and baloxavir against individual virus and coinfection were also studied., Results: The replication of SARS-CoV-2 was significantly interfered when the influenza virus was infected simultaneously or in advance (p < 0.05). On the contrary, the replication of the influenza virus was not affected by the SARS-CoV-2. Molnupiravir monotherapy had significant inhibitory effect on SARS-CoV-2 when the concentration reached to 6.25 μM but did not show any significant anti-influenza activity. Baloxavir was effective against influenza within the dosage range and showed significant effect of anti-SARS-CoV-2 at 16 μM. In the treatment of coinfection, molnupiravir had significant effect for SARS-CoV-2 from 6.25 μM to 100 μM and inhibited H1N1 at 100 μM (p < 0.05). The tested dosage range of baloxavir can inhibit H1N1 significantly (p < 0.05), while at the highest concentration of baloxavir did not further inhibit SARS-CoV-2, and the replication of SARS-CoV-2 significantly increased in lower concentrations. Combination treatment can effectively inhibit influenza H1N1 and SARS-CoV-2 replication during coinfection. Compared with molnupiravir or baloxavir monotherapy, combination therapy was more effective in less dosage to inhibit the replication of both viruses., Conclusions: In coinfection, the replication of SARS-CoV-2 would be interfered by influenza H1N1. Compared with molnupiravir or baloxavir monotherapy, treatment with a combination of molnupiravir and baloxavir should be considered for early treatment in patients with SARS-CoV-2 and influenza coinfection., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
The gut microbiota has been implicated in many cancers through the secretion of blood-traveling metabolites or activation of oncogenic signaling. Currently, specific microbial signatures have been detected in the human breast, which are different from other microbial-rich compartments, such as the intestine and skin. Changes in the breast microbiome profile have been shown to positively or negatively correlate with breast cancer development, progression, and therapeutic outcomes. However, studies regarding the role and underlying mechanism of intratumoral microbiota in breast cancer have remained concealed. This review aimed to provide an overview of the role of the intratumoral microbiome in tumorigenesis and tumor progression, and how these intratumoral microbiota affect breast cancer. We also discuss the potential of using the intratumoral microbiome as a biomarker or treatment alternative in breast cancers., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

- Abstract
Colorectal cancer (CRC) stands as one of the most prevalent form of cancer globally, causing a significant number of deaths, surpassing 0.9 million in the year 2020. According to GLOBOCAN 2020, CRC ranks third in incidence and second in mortality in both males and females. Despite extensive studies over the years, there is still a need to establish novel therapeutic targets to enhance the patients' survival rate in CRC. Nuclear receptors (NRs) are ligand-activated transcription factors (TFs) that regulate numerous essential biological processes such as differentiation, development, physiology, reproduction, and cellular metabolism. Dysregulation and anomalous expression of different NRs has led to multiple alterations, such as impaired signaling cascades, mutations, and epigenetic changes, leading to various diseases, including cancer. It has been observed that differential expression of various NRs might lead to the initiation and progression of CRC, and are correlated with poor survival outcomes in CRC patients. Despite numerous studies on the mechanism and role of NRs in this cancer, it remains of significant scientific interest primarily due to the diverse functions that various NRs exhibit in regulating key hallmarks of this cancer. Thus, modulating the expression of NRs with their agonists and antagonists, based on their expression levels, holds an immense prospect in the diagnosis, prognosis, and therapeutical modalities of CRC. In this review, we primarily focus on the role and mechanism of NRs in the pathogenesis of CRC and emphasized the significance of targeting these NRs using a variety of agents, which may represent a novel and effective strategy for the prevention and treatment of this cancer., (© 2024.

- Abstract
Despite the promising antitumor activity of SHP2 inhibitors in RAS-dependent tumours, overall responses have been limited by their narrow therapeutic window. Like with all MAPK pathway inhibitors, this is likely the result of compensatory pathway activation mechanisms. However, the underlying mechanisms of resistance to SHP2 inhibition remain unknown. The E3 ligase SMURF2 limits TGFβ activity by ubiquitinating and targeting the TGFβ receptor for proteosome degradation. Using a functional RNAi screen targeting all known phosphatases, we identify that the tyrosine phosphatase SHP2 is a critical regulator of TGFβ activity. Specifically, SHP2 dephosphorylates two key residues on SMURF2, resulting in activation of the enzyme. Conversely, SHP2 depletion maintains SMURF2 in an inactive state, resulting in the maintenance of TGFβ activity. Furthermore, we demonstrate that depleting SHP2 has significant implications on TGFβ-mediated migration, senescence, and cell survival. These effects can be overcome through the use of TGFβ-targeted therapies. Consequently, our findings provide a rationale for combining SHP2 and TGFβ inhibitors to enhance tumour responses leading to improved patient outcomes., (© 2023. The Author(s).)

- Abstract
The identification of thermodynamic descriptors of catalytic performance is essential for the rational design of heterogeneous catalysts. Here, we investigate how spillover energy, a descriptor quantifying whether intermediates are more stable at the dopant or host metal sites, can be used to design single-atom alloys (SAAs) for formic acid dehydrogenation. Using theoretical calculations, we identify NiCu as a SAA with favorable spillover energy and demonstrate that formate intermediates produced after the initial O-H activation are more stable at Ni sites where rate-determining C-H activation occurs. Surface science experiments demonstrated that NiCu(111) SAAs are more reactive than Cu(111) while they still follow the formate reaction pathway. However, reactor studies of silica-supported NiCu SAA nanoparticles showed only a modest improvement over Cu resulting from surface coverage effects. Overall, this study demonstrates the potential of engineering SAAs using spillover energy as a design parameter and highlights the importance of adsorbate-adsorbate interactions under steady-state operation.

- Abstract
Active school commuting (ASC) has been proposed as a practical way to inculcate positive physical activity habits in children. This paper reviews the current evidence regarding ASC among children, highlights advances in research techniques and existing limitations in the field, and outlines future implications for research and promotion. A comprehensive literature search was conducted to identify English language studies on ASC among children aged 6-12 years, followed by a narrative review. ASC has witnessed a global decline, despite evidence of its contribution to physical activity levels. Context-dependent factors such as commuting distance and parental safety concerns are consistently identified as key determinants of ASC. Several promising interventions have been identified. Despite the limitations in intervention scope and quality, notable advancements in research techniques, such as multilevel regression and agent-based modelling, have been identified. Effective promotion of ASC to tackle childhood physical inactivity requires collaborative efforts among schools, parents, and the government, and should be tailored to address multilevel determinants within the local context. Future research should leverage recent advancements in research techniques to develop effective promotion strategies, while considering the context-dependent nature of ASC behaviours and addressing existing limitations, including the lack of standardised definitions and limited geographical and age coverage., Competing Interests: The authors declare no conflict of interest.

- Abstract
Background: Acinetobacter nosocomialis (A. nosocomialis) is a glucose non-fermentative, gram-negative bacillus that belongs to the Acinetobacter calcoaceticus-baumannii complex. In recent years, studies have found an increased clinical prevalence of A. nosocomialis. However, given the increasing trend of antibiotic resistance, developing new antibacterial agents is vital. Currently, research regarding bacteriophage therapy against A. nosocomialis is only limited., Methods: Two A. nosocomialis bacteriophages, TCUAN1 and TCUAN2, were isolated from sewage. Experiments such as transmission electron microscopy (TEM), host-range analysis, and sequencing were performed to determine their biological and genomic characteristics. TCUAN2 were further subjected to in vivo experiments and their derived-endolysin were cloned and tested against their bacteria host., Results: Transmission electron microscopy revealed that TCUAN1 and TCUAN2 belong to Myoviridae and Podoviridae, respectively. Both phages show a broad host spectrum and rapid adsorption efficiency. Further biological analysis showed that TCUAN2 possesses a shorter latent period and larger burst size compared to TCUAN1. Because TCUAN2 showed a better antibacterial activity, it was injected into A. nosocomialis-infected mice which resulted in a significant decrease in bacterial load levels in the blood and increased the mice's survival. Finally, genomic analysis revealed that the complete nucleotide sequence of TCUAN1 is 49, 691 bps (containing 75 open reading frames) with a G + C content of 39.3%; whereas the complete nucleotide sequence of TCUAN2 is 41, 815 bps (containing 68 open reading frames) with a G + C content of 39.1%. The endolysin gene cloned and purified from TCUAN2 also showed antibacterial activity when used with a chelator EDTA., Competing Interests: Declaration of competing interest All authors declare that they have no conflict of interest., (Copyright © 2023.

- Abstract
The PI3K/AKT/mTOR (PAM) signaling pathway is a highly conserved signal transduction network in eukaryotic cells that promotes cell survival, cell growth, and cell cycle progression. Growth factor signalling to transcription factors in the PAM axis is highly regulated by multiple cross-interactions with several other signaling pathways, and dysregulation of signal transduction can predispose to cancer development. The PAM axis is the most frequently activated signaling pathway in human cancer and is often implicated in resistance to anticancer therapies. Dysfunction of components of this pathway such as hyperactivity of PI3K, loss of function of PTEN, and gain-of-function of AKT, are notorious drivers of treatment resistance and disease progression in cancer. In this review we highlight the major dysregulations in the PAM signaling pathway in cancer, and discuss the results of PI3K, AKT and mTOR inhibitors as monotherapy and in co-administation with other antineoplastic agents in clinical trials as a strategy for overcoming treatment resistance. Finally, the major mechanisms of resistance to PAM signaling targeted therapies, including PAM signaling in immunology and immunotherapies are also discussed., (© 2023.

Objectives: We examined for differences in pre-left ventricular assist device (LVAD) implantation myocardial transcriptome signatures among patients with different degrees of mitral regurgitation (MR)., Methods: Between January 2018 and October 2019, we collected left ventricular (LV) cores during durable LVAD implantation (n = 72). A retrospective chart review was performed. Total RNA was isolated from LV cores and used to construct cDNA sequence libraries. The libraries were sequenced with the NovaSeq system, and data were quantified using Kallisto. Gene Set Enrichment Analysis (GSEA) and Gene Ontology analyses were performed, with a false discovery rate <0.05 considered significant., Results: Comparing patients with preoperative mild or less MR (n = 30) and those with moderate-severe MR (n = 42), the moderate-severe MR group weighted less (P = .004) and had more tricuspid valve repairs (P = .043), without differences in demographics or comorbidities. We then compared both groups with a group of human donor hearts without heart failure (n = 8). Compared with the donor hearts, there were 3985 differentially expressed genes (DEGs) for mild or less MR and 4587 DEGs for moderate-severe MR. Specifically altered genes included 448 DEGs for specific for mild or less MR and 1050 DEGs for moderate-severe MR. On GSEA, common regulated genes showed increased immune gene expression and reduced expression of contraction and energetic genes. Of the 1050 genes specific for moderate-severe MR, there were additional up-regulated genes related to inflammation and reduced expression of genes related to cellular proliferation., Conclusions: Patients undergoing durable LVAD implantation with moderate-severe MR had increased activation of genes related to inflammation and reduction of cellular proliferation genes. This may have important implications for myocardial recovery., (Published by Elsevier Inc.)

- Abstract
Vascular injury following traumatic knee injury quoted in the literature ranges from 3.3 to 65%, depending on the magnitude and pattern of the injury. Timely recognition is crucial to ensure the revascularization is done within 6 to 8 hours from the time of injury to avoid significant morbidity, amputation, and medicolegal ramifications. We present a case of an ischemic limb following delayed diagnosis of popliteal artery injury after knee dislocation. Even though we have successfully repaired the popliteal artery, the evolving ischemia over the distal limb poses a reconstruction challenge. Multiple surgical debridement procedures were performed to control the local tissue infection. Free tissue transfer with chimeric latissimus dorsi flap was done to resurface the defect. However, the forefoot became gangrenous despite a free muscle flap transfer. His limb appeared destined for amputation in the vicinity of tissue and recipient vessels, but we chose to use a cross-leg free flap as an option for limb salvage., Competing Interests: Conflict of Interest None declared., (The Author(s).

- Abstract
Previous studies have shown that seasonal influenza strikes annually causing millions to fall sick and several hundred thousand to die globally. Hence, universal vaccination is a public health aim to control influenza. The Hong Kong Government started to introduce the School Outreach Vaccination (SOV) program in 2018 to increase vaccination rates in children. This study looked at the impact this had on hospital admissions and estimated vaccination rates in the total population, using a questionnaire-based tool. The SOV program significantly increased vaccination coverage rates with a 1% increase associated with a reduction of 4.3 influenza-related hospital admissions of school-aged children. The estimation of vaccine coverage rates among the under 5-year olds (48.5%), primary school children (69.3%) and over 65-year olds (45.7%), through the questionnaire-based tool, was within the 95% confidence interval of the coverage rates published by the Center for Health Protection of the Hong Kong Government, 47.4%, 68.1% and 45.8%, respectively. Extension of the SOV program should be considered in secondary schools to increase the coverage rates in adolescents. The questionnaire survey may inform government how to achieve universal vaccination for specific age groups.
