    Abstract The mechanism of the development of granulocyte progenitor cells into neutrophils under steady-state and pathological conditions remains unclear. In this study, our results showed that with the development of neutrophils from hematopoietic stem cells to mature neutrophils, the expression level of the Hippo kinase MST1 gradually increased. Mst1-specific deficiency in myeloid cells caused neutrophilia, with an expanded granulocytic compartment resulting from a cell-autonomous increase in the number of granulocyte-macrophage progenitors under steady-state conditions and during Listeria monocytogenes infection. Mechanistically, mTOR and HIF1α signaling are required for regulating the balance between glycolysis and succinate dehydrogenase-mediated oxidative phosphorylation, which is crucial for Mst1-/--induced proliferation of granulocyte-monocyte progenitors, lineage-decision factor C/EBPα expression, and granulopoiesis. HIF1α directly regulated C/EBPα promoter activities. Blocking mTOR and HIF1α or adjusting the balance between glycolysis and succinate dehydrogenase-mediated oxidative phosphorylation reversed the granulopoiesis induced by Mst1-/- under steady-state conditions or infection in mice. Thus, our findings identify a previously unrecognized interplay between Hippo kinase MST1 signaling and mTOR-HIF1α metabolic reprogramming in granulocyte progenitor cells that underlies granulopoiesis.

    Abstract Background: Although the role and mechanism of neutrophils in tumors have been widely studied, the precise effects of aryl hydrocarbon receptor nuclear translocator (ARNT) on neutrophils remain unclear. In this study, we investigated the roles of ARNT in the function of CD11b
    Methods: Wild-type (WT), ARNT myeloid-specific deficient mice and a colitis-associated colorectal cancer mouse model were used in this study. The level and functions of CD11b
    Results: We found that ARNT deficiency drives neutrophils recruitment, neutrophil extracellular trap (NET) development, inflammatory cytokine secretion and suppressive activities when cells enter the periphery from bone marrow upon colorectal tumorigenesis. ARNT deficiency displays similar effects to aryl hydrocarbon receptor (AHR) deficiency in neutrophils. CXCR2 is required for NET development, cytokine production and recruitment of neutrophils but not the suppressive activities induced by Arnt
    Conclusion: Our results defined a new role for the transcription factor ARNT in regulating neutrophils recruitment and function and the gut microbiota with implications for the future combination of gut microbiota and immunotherapy approaches in colorectal cancer.

    Abstract Objective: It is unknown how well menu labelling schemes that enforce the display of kilojoule (kJ) labelling at point-of-sale have been implemented on online food delivery (OFD) services in Australia. This study aimed to examine the prevalence of kJ labelling on the online menus of large food outlets with more than twenty locations in the state or fifty locations nationally. A secondary aim was to evaluate the nutritional quality of menu items on OFD from mid-sized outlets that have fewer locations than what is specified in the current scheme.
    Design: Cross-sectional analysis. Prevalence of kJ labelling by large food outlets on OFD from August to September 2022 was examined. Proportion of discretionary ('junk food') items on menus from mid-sized outlets was assessed.
    Setting: Forty-three unique large food outlets on company (e.g. MyMacca's) and third party OFD (Uber Eats, Menulog, Deliveroo) within Sydney, Australia. Ninety-two mid-sized food outlets were analysed.
    Participants: N/A.
    Results: On company OFD apps, 35 % (7/23) had complete kJ labelling for each menu item. In comparison, only 4·8 % (2/42), 5·3 % (2/38) and 3·6 % (1/28) of large outlets on Uber Eats, Menulog and Deliveroo had complete kJ labelling at all locations, respectively. Over three-quarters, 76·3 % (345/452) of menu items from mid-sized outlets were classified as discretionary.
    Conclusions: Kilojoule labelling was absent or incomplete on a high proportion of online menus. Mid-sized outlets have abundant discretionary choices and yet escape criteria for mandatory menu labelling laws. Our findings show the need to further monitor the implementation of nutrition policies on OFD.

    Abstract Myeloid-derived suppressor cells (MDSCs) are a group of immunosuppressive cells that play crucial roles in promoting tumor growth and protecting tumors from immune recognition in tumor-bearing mice and cancer patients. Recently, it has been shown that the metabolic activity of MDSCs plays an important role in the regulation of their inhibitory function, especially in the processes of tumor occurrence and development. The MDSC metabolism, such as glycolysis, fatty acid oxidation and amino acid metabolism, is rewired in the tumor microenvironment (TME), which enhances the immunosuppressive activity, resulting in effector T cell apoptosis and suppressive cell proliferation. Herein, we summarized the recent progress in the metabolic reprogramming and immunosuppressive function of MDSCs during tumorigenesis.

    Abstract Background: The feasibility and safety of administrating a small amount of oral fluid to children in the early recovery period following tonsillectomy under general anesthesia to reduce the thirst and its associated restlessness remain unknown.
    Methods: This study was approved by the institutional ethics committee and adhered to the CONSORT guidelines. Pediatric patients undergoing tonsillectomy who met the inclusion and exclusion criteria of our study were randomized into the study and control groups. In the study group, patients were given a small amount of water instantly after recovering from general anesthesia, which included the recovery of the cough and deglutition reflex, and attaining grade V of muscle strength. The control group was given a small amount of water at 4 to 6 h after the operation. The incidence of nausea and vomiting and the degree of thirst relief were measured and compared between the two groups.
    Results: Three hundred patients were randomized into each group. There was no significant difference in the incidence of nausea and vomiting at 20 min after drinking water between the two groups (P > 0.05). The thirst score of children over 5 years old in the study group was significantly lower than that of the control group (P < 0.05).
    Conclusion: Early administration of a small amount of oral fluid to children following tonsillectomy and recovering from general anesthesia is not only safe but also effective in reducing postoperative thirst.

    Abstract Background: Oral hydration has typically not been administered for between 4 and 6 h postoperative for children's safety in China. But children are more likely to suffer from apnea, crying and agitation, wound bleeding, and other complications during the post-anesthesia recovery period because of thirsty and fear. This Prospective, randomized study sought to assess the compare the early and late oral hydration (EOH and DOH, respectively) in children following general anesthesia, with the goal of assessing relative safety and tolerability and thereby improving patient comfort.
    Methods: A total of 2000 children corresponding to the American Society of Anesthesiology (ASA) I-III were randomized into an EOH group (n = 1000) and a DOH group (n = 1000). For the former group, children were administered a small amount of drinking water following recovery of the swallowing reflex, and children's vital signs were monitored for 20 min in a postanesthesia care unit (PACU). DOH group patients received water at 4 h following general anesthesia). All patients underwent monitoring to assess their thirst, satisfaction, oropharyngeal discomfort, nausea, and vomiting.
    Results: Complete data were collected from a total of 1770 patients (EOH = 832, DOH = 938) and was compared via chi-squared and t-tests as appropriate. There was no hypoxemia in either group, nor did the incidence of nausea and vomiting differ between the two groups (P > 0.05). The thirst score of the EOH group was significantly decreased relative to the DOH group in the children over 5 years old after drinking for 10 to 20 min (P < 0.05).
    Conclusions: For children undergoing general anesthesia, a small amount of drinking water in the early stages of recovery will not increase the incidence of nausea, vomiting, or hypoxemia, but will decrease thirst and improve satisfaction. It is important, however, that medical staff carefully monitor the swallowing reflex and vital signs of all children.
    Trial registration: This study was registered on the Chinese Clinical Trial Registry (ChiCTR-IOR-16008197) (http://www.chictr.org.cn/index.aspx. On April 2, 2016 the first patients was enrolled and on March 31, 2016 the trial was registered).

    Abstract The gut of mammals is considered as a harmonious ecosystem mediated by intestinal microbiota and the host. Both bacteria and mammalian immune cells show region-related distribution characteristics, and the interaction between the two could be demonstrated by synergetic roles in maintaining intestinal homeostasis and dysregulation in intestinal inflammation. The harmonious interplay between bacteria and host requires fine-tuned regulations by environmental and genetic factors. Thus, the disturbed immune response to microbial components or metabolites and dysbiosis related to immunodeficiency are absolute risk factors to intestinal inflammation and cancer. In this review, we discuss the crosstalk between bacteria and host immunity in the gut and highlight the critical roles of bidirectional regulation between bacteria and the mammalian immune system involved in intestinal inflammation.

    Abstract Microbiota is a group of microbes coexisting and co-evolving with the immune system in the host body for millions of years. There are mutual interaction between microbiota and the immune system. Immune cells can shape the populations of microbiota in the gut of animals and humans, and the presence of microbiota and the microbial products can regulate the development and function of the immune cells in the host. Although microbiota resides mainly at the mucosa, the effect of microbiota on the immune system can be both local at the mucosa and systemic through the whole body. At the mucosal sites, the presences of microbiota and microbial products have a direct effect on the immune cells. Microbiota induces production of effectors from immune cells, such as cytokines and inflammatory factors, influencing the further development and function of the immune cells. Experimental data have shown that microbial products can influence the activity of some key factors in signaling pathways. At the nonmucosal sites, such as the bone marrow, peripheral lymph nodes, and spleen, microbiota can also regulate the development and function of the immune cells via several mechanisms in mice, such as introduction of chromatin-level changes through histone acetylation and DNA methylation. Given the important effect of microbiota on the immune system, many immunotherapies that are mediated by immune system rely on gut microbiota. Thus, the study of how microbiota influences immune system bring a potential therapy prospect in preventing and treating diseases.
