Macrophages are critical immune cells present in virtually every tissue, where they contribute to tissue homeostasis beyond their traditional immune roles. Past and recent evidence highlights their involvement in endocrine regulation, particularly within the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes. This review explores the ontogeny and function of macrophages residing in the hypothalamus, pituitary, adrenals, and gonads, emphasizing their contributions to hormonal output and endocrine homeostasis. Macrophages in the hypothalamus and pituitary modulate neuroendocrine signalling, impacting stress and reproductive hormone production. In the adrenal glands, distinct macrophage subsets regulate glucocorticoid and mineralocorticoid synthesis, influencing systemic metabolism and blood pressure. Gonadal macrophages contribute to steroidogenesis and fertility, with roles in testosterone production, ovarian folliculogenesis, and corpus luteum maintenance. The emerging understanding of macrophage regulation of endocrine function may seed novel therapeutic approaches for endocrine disorders. Future research should further elucidate the molecular mechanisms underlying macrophage regulation of hormone production and explore their implications for metabolic, immune, and reproductive health.

Cardiac macrophages (CMs) are the most abundant immune cell type in the heart. They are critical for maintaining cardiac homeostasis and in the orchestration of immune responses to ischemic and non-ischemic cardiomyopathies. Their functions are highly heterogeneous and regulated by their tissue microenvironment. CMs have high plasticity, which allows them to perform various functions in the myocardium to bring about homeostasis within the cardiovascular system (CVS). CMs also play critical roles in coronary development and angiogenesis, tissue repair and remodeling, cardiac conduction and in the clearance of necrotic and apoptotic cells. However, there is a paucity of studies on the biology of cardiac macrophages in both steady state and disease, especially, in humans. In this review, we discuss the multifaceted roles of CMs in the heart, focusing on their ontogeny, homeostatic functions and immunological responses during inflammation and reparative processes post-injury. We highlight the heterogeneity of CMs in their ontogeny, phenotypes and functions as well as their roles in the pathogenesis of pathological conditions such as myocarditis, myocardial fibrosis and heart failure. Understanding the unique characteristics of cardiac macrophages in the cardiac milieu is critical for the development of macrophage-specific therapeutic interventions to alleviate the global burden of cardiovascular disease (CVD). Therefore, future studies should focus on further improving the understanding of the biology of cardiac macrophages to harness their potential as therapeutic targets for cardiovascular disorders.

The new treatment goal for chronic myeloid leukemia (CML) is treatment-free remission, which requires the achievement and maintenance of a deep molecular response (DMR) using a tyrosine kinase inhibitor (TKI). However, only a limited number of patients achieve or maintain DMR. TM5614, a PAI1 inhibitor, can bring quiescent hematopoietic stem cells from the bone marrow niche into the cell cycle. Thus, the combination of TM5614 and TKI may eradicate CML cells. Currently, a phase III clinical trial is confirming the efficacy of TM5614 and TKI combination therapy.

N6-methyladenosine (m6A) is an mRNA modification with important roles in gene expression. In African trypanosomes, this post-transcriptional modification is detected in hundreds of transcripts, and it affects the stability of the variant surface glycoprotein (VSG) transcript in the proliferating blood stream form. However, how the m6A landscape varies across the life cycle remains poorly defined. Using full-length, non-fragmented RNA, we immunoprecipitated and sequenced m6A-modified transcripts across three life cycle stages of Trypanosoma brucei – slender (proliferative), stumpy (quiescent), and procyclic forms (proliferative). We found that 1037 transcripts are methylated in at least one of these three life cycle stages. While 21% of methylated transcripts are common in the three stages of the life cycle, globally, each stage has a distinct methylome. Interestingly, 47% of methylated transcripts are detected in the quiescent stumpy form only, suggesting a critical role for m6A when parasites exit the cell cycle and prepare for transmission by the tsetse fly. In this stage, we found that a significant proportion of methylated transcripts encodes for proteins involved in RNA metabolism, which is consistent with their reduced transcription and translation. Moreover, we found that not all major surface proteins are regulated by m6A, as procyclins are not methylated, and that, within the VSG repertoire, not all VSG transcripts are demethylated upon parasite differentiation to procyclic form. This study reveals that the m6A regulatory landscape is specific to each life cycle stage, becoming more pervasive as T. brucei exits the cell cycle.

The functions of activating transcription factor 3 (ATF3) within the human bladder remain unexplored. This study delves into the expressions, functions, and regulatory mechanisms of ATF3 in human bladder cancer.
Material and methods
Gene expressions were determined by immunoblot, RT-qPCR, and reporter assays. Assays of Ki67, colony formation, Matrigel invasion, and the xenograft animal study were used to assess the cell proliferation, invasion, and tumorigenesis in vitro and in vivo. Silico analysis from TCGA database examined the correlations between GDF15 and ATF3 expressions, clinicopathologic features, and progression-free survival rates.
Results
Silico analysis confirmed that ATF3 is an antitumor gene, and the expression positively correlates with GDF15 in bladder cancer tissues. Multivariate analysis revealed that low ATF3/GDF15 but not a single low expression of ATF3 is an independent prognostic factor for progression-free survival of bladder cancer patients. Ectopic overexpression of ATF3 downregulated cell proliferation and invasion in bladder cancer cells in vitro, while ATF3-knockdown reversed these results. Knockdown of ATF3 upregulated EMT markers to enhance cell invasion in vitro and downregulated GDF15, NDRG1, and KAI-1 to elevate tumor growth in vivo. The activation of metformin on ATF3 and GDF15 in bladder cancer cells was blocked by SB431542, a TGFβ receptor inhibitor. ATF3 positively regulated GDF15 expression in bladder cancer cells through a feedback loop.
Conclusions
Our results identify that ATF3 is a metformin-upregulated antitumor gene. Results of Silico analysis align with cell-based studies suggesting that low ATF3/GDF15 could be a negative prognostic marker for bladder cancer.

Objective
The aim of this study was twofold: to assess the annual pharmaceutical savings associated with the treatment of cancer patients at Marqués de Valdecilla University Hospital and to estimate the cost of innovative antineoplastic therapies that patients receive as experimental treatment, both during clinical trials throughout 2020.
Material and methods
An observational and financial analysis of the drug cost related to clinical trials was applied. Direct cost savings to the Regional Health System of Cantabria and the cost of innovative therapies used as an experimental treatment in clinical trials were quantified.
Results
This study includes 38 clinical trials with a sample of 101 patients. The clinical trials analyzed provide a total cost savings of €603,350.21 and an average cost saving of €6630.22 per patient. Furthermore, the total investment amounts to €789,892.67, with an average investment of €15,488.09 per patient.
Conclusions
Clinical trials are essential for the advancement of science. Furthermore, clinical trials can be a significant source of income for both hospitals and Regional Health Systems, contributing to their financial sustainability.

Background
The incidence of autoimmune diseases is increasing in developed countries, possibly due to the modern Western diet and lifestyle. We showed earlier that polysaccharides derived from the medicinal fungus Hirsutella sinensis produced anti-inflammatory, anti-diabetic and anti-obesity effects by modulating the gut microbiota and increasing the abundance of the commensal Parabacteroides goldsteinii in mice fed with a high-fat diet.
Methods
We examined the effects of the prebiotics, H. sinensis polysaccharides, and probiotic, P. goldsteinii, in a mouse model of imiquimod-induced systemic lupus erythematosus.
Results
The fungal polysaccharides and P. goldsteinii reduced markers of lupus severity, including the increase of spleen weight, proteinuria, and serum levels of anti-DNA auto-antibodies and signal transducer and activator of transcription 4 (STAT4). Moreover, the polysaccharides and P. goldsteinii improved markers of kidney and liver functions such as creatinine, blood urea nitrogen, glomerulus damage and fibrosis, and serum liver enzymes. However, the prebiotics and probiotics did not produce consistent improvements in gut microbiota composition, colonic histology, or expression of tight junction proteins in colon tissues.
Conclusions
Our results indicate that H. sinensis polysaccharides and the probiotic P. goldsteinii can reduce lupus markers in imiquimod-treated mice. These prebiotics and probiotics may therefore be added to other interventions conducive of a healthy lifestyle in order to counter autoimmune diseases.
背景:在发达国家,自身免疫性疾病的发病率正在上升,这可能与现代西方饮食和生活方式有关。我们早些时候研究发现,从药用真菌中华大孔菌中提取的多糖通过调节肠道微生物群和增加高脂饮食喂养的小鼠体内共生菌 Parabacteroides goldsteinii 的丰度,产生抗炎、抗糖尿病和抗肥胖的作用:我们在咪喹莫特诱导的系统性红斑狼疮小鼠模型中研究了益生菌中华蘑菇多糖和益生菌金丝桃的作用:结果:真菌多糖和金孢子菌降低了狼疮严重程度的指标,包括脾脏重量增加、蛋白尿、血清中抗 DNA 自身抗体和转录信号转导子和激活子 4(STAT4)的水平。此外,金丝桃多糖和金丝桃还能改善肝肾功能指标,如肌酐、血尿素氮、肾小球损伤和纤维化以及血清肝酶。然而,益生元和益生菌并不影响肠道微生物群的组成、结肠组织学或结肠组织中紧密连接蛋白的表达:我们的研究结果表明,中华猪多糖和益生菌金丝桃可以减少咪喹莫特治疗小鼠的狼疮指标。因此,这些益生元和益生菌可与其他有利于健康生活方式的干预措施相结合,以对抗自身免疫性疾病。

The electromagnetic characteristics of many environments have changed significantly in recent decades. This is in large part due to the increased presence of equipment that emits electromagnetic radiation and materials that may often readily gain excess charge. The presence of excess charge can often increase the risk of infection from pathogens and the likelihood of individuals experiencing compromised performance, respiratory problems, and other adverse health issues from increased uptake of particulate matter. It is proposed that adopting improved electromagnetic hygiene measures, including optimized humidity levels, to reduce the presence of inappropriate levels of electric charge can help reduce the likelihood of ill health, infection, and poor performance arising from contaminant inhalation and deposition, plus reduce the likelihood of medical devices and other electronic devices getting damaged and/or having their data compromised. It is suggested that such measures should be more widely adopted within clinical practice guidelines and water, sanitation, and hygiene programs.

Background
Purpose of this study was to determine what key aspects of function should be incorporated to make up a pre-intervention assessment profile of a child with Developmental Coordination Disorder (DCD); more specifically, what aspects of functioning are implicated in DCD and what is their relative impact?
Methods
A systematic review and meta-analysis were conducted, for which Pubmed, Web of Science, Scopus and Proquest were searched (last update: April 2023, PROSPERO: CRD42023461619). Case-control studies were included to determine point estimates for performances on field-based tests in different domains of functioning. The risk of bias was assessed, and the level of evidence was estimated. Random-effect meta-analyses were performed to calculate the pooled standardized mean differences for domains of functioning and subgrouping was done for clinically relevant subdomains. Heterogeneity was determined with I2.
Results
121 papers were included for analyses. Data of 5923 children with DCD were included (59.8% boys) and 23 619 Typically Developing (TD) children (45.8% boys). The mean (SD) age of the DCD group was 10.3y (1.2) and 9.3y (1.3) for the TD children. Moderate evidence was found for motor performance, executive functions, sensory processing and perceptions, cognitive functions and sports and leisure activities to be affected in children with DCD.
Conclusion
Differences between the two groups varied per domain of functioning. This emphasizes the diversity present within children with DCD and provides a rationale for explaining the heterogeneity in this patient group. Yet, results highlight the potential involvement of all these domains and call for clinicians to be alert not only to examine motor skill difficulties but also other aspects of function. Results indicate the need to develop an individualized pre-intervention multi-dimensional assessment profile for each child with DCD. It also supports the important role that clinicians play in an interdisciplinary team to tackle the difficulties encountered by children with DCD.

Liver transplantation (LT) is considered the ideal treatment for hepatocellular carcinoma (HCC) concurrent with underlying cirrhotic liver disease. As well-known, LT for HCC based on the Milan criteria has shown satisfactory outcomes. However, numerous expanded transplantation criteria were proposed to benefit more patients for LT and showed comparable survivals as well. In addition, a modest expansion of transplantation criteria for HCC may be acceptable on the basis of the consensus within the transplantation community. Nonetheless, LT in patients with advanced HCC and portal vein tumor thrombosis (PVTT) recently has received attention and has been reported by many transplantation centers despite being contraindicated. Of those, the LT outcomes in certain HCC patients with PVTT were favorable. Additionally, the advancement of multimodality treatments and the evolution of systemic therapies have emerged as promising therapeutic options for downstaging advanced HCC prior to LT. Somehow, advanced HCC with PVTT could be downstaged to become eligible for LT through these multidisciplinary approaches. Although the available evidence of LT for HCC with PVTT is limited, it is hoped that LT may soon be more widely indicated for these patients. Nevertheless, several unknown factors associated with LT for HCC remain to be explored. Herein, this review aimed to update the developments in LT for patients with advanced HCC.
