Breast cancer remains one of the leading causes of cancer-related deaths worldwide. Early detection of breast cancer significantly improves outcomes and survival rates, minimizing treatments. Imaging techniques are critical in identifying abnormalities and diagnosing breast cancer at its earliest stages, often before clinical symptoms emerge. Mammography remains standard for screening in average-risk women, while supplementary methods like ultrasound, magnetic resonance imaging, and tomosynthesis enhance detection rates, particularly in women with dense breasts or those at high risk. Given that certain factors, such as family history, age, genetic mutations, and breast density, affect the risk of developing breast cancer, some women may benefit from earlier or more frequent screenings. Personalized screening protocols are becoming more common, tailoring the type and frequency of imaging to the individual’s risk profile. Newer technologies, such as molecular breast imaging and contrast-enhanced mammography show promise but require further validation for widespread use. In conclusion, imaging techniques including mammography, ultrasound, magnetic resonance imaging, and newer technologies like three-dimensional mammography and molecular breast imaging are essential tools in the early detection of breast cancer, leading to better outcomes for patients. This literature review provides an overview of current breast cancer imaging methods, their role in early diagnosis, and their effectiveness and limitations.

Amyotrophic lateral sclerosis (ALS) and other motor neuron diseases (MNDs) are major global causes of death. However, their global incidence, mortality, and disability-adjusted life years remain largely unknown, despite their importance for disease prevention and resource allocation. We therefore examined the global epidemiology of ALS/MNDs.

This study analyzed data from the Global Burden of Disease 2021 database for 204 regions (1990–2021), focusing on ALS/MNDs. Data from the world, China, and the G8 countries were analyzed separately. Age-standardized incidence rates were reported for the 1990s, 2000s, 2010s, and 2020s.

A rising global burden of ALS/MNDs, with significant variations across regions and levels of the social development index, was observed in the Global Burden of Disease database. A significant overlap of etiology between neurological diseases and ALS was also identified. Among the G8 countries and China, China and the USA exhibited the highest prevalence rates in the 1990s, 2000s, 2010s, and 2020s, with China showing 3.3 per 10,000 and the USA 4.0 per 10,000 in the 2020s.

Understanding the common etiologies of ALS/MNDs is key to their effective control. Recommended strategies include pollution control, chemical and radiation safety management, disease monitoring, public health education, multi-departmental collaboration, and scientific research.

Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract and primarily includes ulcerative colitis and Crohn’s disease. As the number of patients suffering from IBD increases, diagnosis and treatment have become pressing yet challenging tasks. A major challenge is that patients with IBD often do not exhibit characteristic symptoms, making it difficult to distinguish IBD from other intestinal abnormalities. Endoscopy is the most conventional method used to diagnose IBD; however, this technique is invasive and costly. Therefore, there is a need to develop affordable, non-invasive diagnostic methods, which underscores the importance of identifying biomarkers specific to IBD. It is now well established that the gut microbiome plays a significant role in the development of IBD, and changes in the abundance of various gut organisms have been widely studied to identify microbial signatures associated with the disease. This review discusses the current state of knowledge regarding biomarkers in IBD, with a primary focus on the gut microbiome, associated metabolic signatures, and their links with immunological biomarkers. These biomarkers will help propose an integrative model to better understand the pathophysiology of this complex disease. Such an integrated approach also offers insights into potential therapeutic targets for designing more effective treatment strategies for patients.

Metabolic dysfunction-associated steatotic liver disease (MASLD), the most common chronic liver disorder worldwide, results from multidimensional network dysregulation involving lipid metabolism imbalance, insulin resistance, oxidative stress, chronic inflammation, and gut-liver axis disruption. Silent information regulator 1 (SIRT1), an NAD+-dependent deacetylase, functions as a central regulator of metabolic homeostasis and a key mediator in immune microenvironment remodeling and inter-organ communication. This review systematically describes the multi-target mechanisms of SIRT1 in MASLD pathogenesis through its regulation of critical factors, including peroxisome proliferator-activated receptor gamma coactivator 1-α, Forkhead Box O, and nuclear factor kappa-light-chain-enhancer of activated B cells, which govern hepatocyte lipid remodeling, mitochondrial quality control, autophagy–endoplasmic reticulum stress balance, and Kupffer cell/T cell polarization. This work introduces, for the first time, the concept that SIRT1 mediates systemic regulation of MASLD via coordinated “metabolism–inflammation–organ axis” interactions. Recent studies indicate that natural compounds (e.g., resveratrol, curcumin) improve gut-liver barrier function through microbiota–SIRT1 interactions, while synthetic activators (SRT1720) and NAD+ precursors (NMN) enhance hepatocyte antioxidant capacity and fatty acid β-oxidation. This innovative analysis highlights the spatiotemporal specificity of various SIRT1 activators, emphasizing that tissue-selective delivery and dynamic dosage optimization are crucial for overcoming clinical translation challenges. By integrating mechanistic and translational insights, this review provides a novel foundation for precision intervention strategies targeting SIRT1 network reprogramming.

Chronic hepatitis B virus (HBV) infection remains a major cause of liver diseases, including cirrhosis and hepatocellular carcinoma. Reliable biomarkers for assessing viral replication, liver damage, and predicting clinical outcomes are essential for effective patient management. This review focuses on two promising biomarkers: serum HBV RNA and hepatitis B core-related antigen, both of which show strong correlations with viral replication and disease progression. Serum HBV RNA levels reflect the quantity and transcriptional activity of intrahepatic covalently closed circular DNA, providing insights into viral replication. They also correlate with other markers of replicative activity and have predictive value for key clinical outcomes, including hepatitis B e antigen and hepatitis B surface antigen seroconversion, relapse after therapy cessation, and liver fibrosis. Similarly, hepatitis B core-related antigen is closely associated with covalently closed circular DNA levels, correlates with markers of viral replication, and shows promise in predicting liver fibrosis, cirrhosis, and the risk of hepatocellular carcinoma. This review highlights the potential of both biomarkers for monitoring disease progression and guiding therapeutic decisions, particularly in the context of personalized treatment strategies and risk assessment for liver-related complications.

Surgical management of supratentorial spontaneous intracerebral hemorrhage (sICH) remains controversial. Craniotomy (CT) reduces mortality but offers limited functional benefits. Neuroendoscopic surgery (NE) has emerged as a viable alternative, providing improved outcomes. Recent randomized controlled trials (RCTs) strengthen ongoing comparisons between these approaches. This meta-analysis systematically evaluates the efficacy and safety of NE versus CT for supratentorial sICH.

RCTs comparing NE versus CT for supratentorial sICH were systematically identified through comprehensive searches of PubMed, Embase, Cochrane Library, and Web of Science databases. Evaluated outcomes included functional outcome (favorable or unfavorable), hematoma evacuation rate, mortality, intraoperative blood loss, operation time, rebleeding, infection (including pulmonary and intracranial), and total complications. Cochrane’s Risk of Bias-2 tool was employed to assess the risk of bias across the included studies.

Eight RCTs were included, comprising 1,354 patients. NE demonstrated a significant advantage in achieving a favorable functional outcome (risk ratio: 1.43; 95% confidence interval (CI) 1.22, 1.68; p < 0.001) and a notably higher hematoma evacuation rate (mean difference (MD): 7.60; 95% CI 3.59, 11.61; p < 0.001). Additionally, NE was associated with a marked reduction in intraoperative blood loss (MD: −152.95; 95% CI −261.68, −44.22; p = 0.006) and a substantial reduction in operative time (MD: −118.49; 95% CI −147.30, −89.67; p < 0.001). The incidences of unfavorable functional outcome and total complications, including pulmonary infection, were significantly lower in the NE group. However, NE did not lead to an improvement in the mortality rate, and there were no significant differences in the incidences of postoperative rebleeding or intracranial infection between the two groups.

These findings suggest that NE offers distinct advantages in terms of functional outcomes and surgical efficiency for patients with supratentorial sICH. Future studies should involve larger, higher-quality RCTs, and neuroendoscopic techniques should be continuously optimized.

Recent advancements in cancer immunotherapy have highlighted glypican-3 (GPC3) as a prominent target for treating hepatocellular carcinoma (HCC). However, approximately 10% to 30% of HCC patients exhibit low or absent GPC3 expression on the surface of tumor cells, which limits the feasibility of GPC3-targeted therapies. Consequently, it is essential for patients to undergo pre-diagnostic assessments of GPC3 expression in tumor cells to evaluate their suitability for GPC3-directed therapy. Although various methods have been developed to specifically detect GPC3 as a biomarker for treatment and prognosis, the diagnostic approaches currently employed in clinical studies remain relatively limited. Here, we provide a comprehensive overview of the clinical development of GPC3-targeted therapeutics, clinical trials in GPC3-positive HCC, and current methods for detecting GPC3 expression, highlighting their advantages and limitations. Furthermore, we explore the potential of integrating targeted therapy with various GPC3 detection modalities tailored to different pathological stages. This integration not only provides insights into the selection of effective methods for detecting GPC3 expression but also has the potential to significantly improve the clinical outcomes of patients with liver cancer. By simultaneously assessing the advantages and disadvantages of these methods, this review aims to establish a theoretical foundation for the clinical selection of appropriate GPC3 detection strategies for targeted therapy.

This review explores the complex interplay between the microbiome and human aging, highlighting how dysbiosis impacts host physiology and health, particularly in relation to genomic stability and telomere attrition. Recent advances in cellular and molecular biology have underscored the role of both intrinsic and extrinsic factors in human aging, with the microbiome emerging as a key determinant of host physiology and health. Dysbiosis—disruptions in microbiome composition—is linked to various age-related diseases and impacts genomic stability and telomere attrition, the progressive shortening of telomeres that limits cell division and contributes to aging. This review examines how microbiome dynamics influence aging by triggering inflammation, oxidative stress, immune dysregulation, and metabolic dysfunction, all of which affect two primary hallmarks of aging: genomic instability and telomere attrition. Understanding these interactions is essential for developing targeted interventions to restore microbiome balance and promote healthy aging, offering potential treatments to extend healthspan and alleviate aging-related diseases. The convergence of microbiome and aging research promises transformative insights and new avenues for improving global population well-being.

Castleman disease (CD) is a lymphoproliferative condition with a broad range of morphological and clinical presentations. It is categorized into distinct pathological and clinical subtypes, including localized unicentric CD, idiopathic multicentric CD, and human herpesvirus 8-associated or human herpesvirus 8-negative variants. Diagnosing CD requires adherence to internationally recognized guidelines that integrate clinical, laboratory, and histological findings. However, distinguishing CD from other diseases can be complex, as numerous benign and malignant conditions can mimic its features. Additionally, individuals diagnosed with CD are at an elevated risk of developing various malignancies. In this article, we reviewed benign and malignant conditions that can mimic CD.

Literature search is conducted and reviewed.

Mimickers of CD include follicular hyperplasia, indolent B-cell lymphoproliferative disorders, peripheral T-cell malignancies, classic Hodgkin lymphoma, follicular dendritic cell tumors, plasma cell disorders, immunoglobulin G4 -related lymphadenopathy, autoimmune-associated lymphadenopathy, infectious causes of lymphadenopathy, and systemic syndromes like POEMS and TAFRO. Various malignancies are associated with CD, including plasma cell proliferations, lymphomas, follicular dendritic cell neoplasms, and Kaposi sarcoma.

This review explores the differential diagnoses and neoplasms linked to CD, emphasizing their role in accurate classification, treatment decisions, and patient management. A comprehensive understanding of CD and its mimickers is crucial for ensuring accurate diagnosis and appropriate patient management in clinical practice.

Autoimmune hepatitis (AIH) is a chronic inflammatory disease with unclear etiology. Various vaccines have been reported as triggers of AIH. Recently, with the ongoing COVID-19 pandemic and widespread vaccination worldwide, several cases of COVID-19 vaccination-associated (CA) AIH, occurring with or without COVID-19 infection, have been reported.

In this report, we describe a 66-year-old female who developed biopsy-proven acute-onset autoimmune hepatitis after receiving four doses of the COVID-19 vaccine and experiencing one COVID-19 infection in 2022. The patient was immediately treated with prednisone. Her liver enzymes gradually decreased to the normal range after treatment. In addition, we reviewed 20 cases of CA-AIH reported from multiple countries. The summarized data showed that CA-AIH and classical AIH share some clinical, serological, and histopathological features, such as female predominance and a middle-aged distribution. All patients had some positive circulating autoantibodies, including anti-nuclear antibody and/or positive anti-smooth muscle antibody. Histologically, CA-AIH showed a more acute onset compared to classical AIH, which typically presents with more chronic hepatitis.

This case report provides additional evidence supporting an association between COVID-19 vaccination and/or infection and AIH, suggesting more causality than coincidence.
