The World Health Organization System for Reporting Pancreaticobiliary Cytopathology introduces a seven-tier category system to standardize terminology and nomenclature. This system includes the following categories: Insufficient/non-diagnostic, benign/negative for malignancy, atypia, pancreaticobiliary neoplasm low-risk/grade, pancreaticobiliary neoplasm high-risk/grade, suspicious for malignancy, and malignant categories. Adopting a standardized reporting scheme facilitates consistent diagnostic criteria among pathologists, thereby reducing report variability and enhancing communication with the clinical team for optimal patient management. The report also highlights the role of critical ancillary tests in improving diagnostic accuracy for pancreatic lesions and discusses practical approaches to managing solid and cystic pancreatic lesions.

Achalasia is a rare esophageal motility disorder characterized by the inability of the lower esophageal sphincter to relax and the absence of normal esophageal peristalsis. This condition leads to difficulties in swallowing (dysphagia), regurgitation of food, and chest pain. Clinical observations suggest an association between achalasia and esophageal tumors, as achalasia can increase the risk of developing esophageal cancer. We explore the pathophysiology of achalasia, its clinical manifestations, and the associated risk of esophageal malignancies, supported by recent research and clinical evidence, including specific case studies.

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.

Liver cancer is a digestive system malignancy that poses a significant public health challenge globally. This study aimed to analyze and compare the epidemiological trends of liver cancer attributed to hepatitis B (LCHB) and alcohol use (LCAL) over the past 32 years.

Data on mortality and disability-adjusted life years for LCHB and LCAL in China, globally, and across five sociodemographic index regions were obtained from the Global Burden of Disease 2021 database and comprehensively analyzed.

In 2021, the global and Chinese death counts and disability-adjusted life years attributed to LCHB and LCAL showed substantial increases compared to 1990. China had the highest number of deaths from LCHB and LCAL among 204 countries and regions. Gender and age disparities were notable, with males and those aged 40–75 years bearing a higher burden than females and other age groups. Global age-period-cohort analysis revealed an escalating risk of death from LCHB with age, alongside a lower risk in younger cohorts and more recent periods. The mortality risk for LCAL also increased with age but exhibited distinct cohort and period effects compared to LCHB. Decomposition analysis indicated that shifts in the global burden of LCHB and LCAL were influenced by population growth, with population aging playing a crucial role in China.

A significant burden of LCHB and LCAL persists, highlighting the need for tailored prevention, screening, and control strategies to mitigate their incidence, as well as the identification of advanced therapeutics to reduce mortality.

Early determination of prognosis in patients with acute-on-chronic liver failure (ACLF) is crucial for optimizing treatment options and liver allocation. This study aimed to identify risk factors associated with ACLF and to develop new prognostic models that accurately predict patient outcomes.

We retrospectively selected 1,952 hospitalized patients diagnosed with ACLF between January 2010 and June 2018. This cohort was used to develop new prognostic scores, which were subsequently validated in external groups.

The study included 1,386 ACLF patients and identified six independent predictors of 28-day mortality through multivariate analysis (all p < 0.05). The new score, based on a multivariate regression model, demonstrated superior predictive accuracy for both 28-day and 90-day mortalities, with Areas under the ROC curves of 0.863 and 0.853, respectively (all p < 0.05). This score can be used to stratify the risk of mortality among ACLF patients with ACLF, showing a significant difference in survival between patients categorized by the cut-off value (log-rank (Mantel–Cox) χ2 = 487.574 and 606.441, p = 0.000). Additionally, the new model exhibited good robustness in two external cohorts.

This study presents a refined prognostic model, the Model for end-stage liver disease-complication score, which accurately predicts short-term mortality in ACLF patients. This model offers a new perspective and tool for improved clinical decision-making and short-term prognostic assessment in ACLF patients.

Chlorella vulgaris is a green, photosynthetic microalga in the phylum Chlorophyta. The goal of our study was to perform a bioinformatics analysis of Photosystem I P700 chlorophyll a apoprotein A2, one of its photosynthesis-related proteins, and to hunt for potent bioactive peptides.

To generate peptides and estimate the safety and efficacy of each bioactive peptide, we employed the tools BIOPEP-UWM™, PeptideRanker, DBAASP, and ToxinPred. PepDraw was used to understand the physicochemical properties and primary chemical structures of the selected bioactive peptides.

The liberated peptides exhibit up to 17 distinct bioactivities, as shown by the in silico digestion of the protein using several proteolytic enzymes. The peptides with bioactivities are listed as angiotensin-converting enzyme inhibitor, dipeptidyl peptidase IV inhibitor, dipeptidyl peptidase III inhibitor, antioxidative, renin inhibitor, glucose uptake stimulator, neuropeptide regulator (regulating stomach mucosal membrane activity and ion flow), antithrombotic, anti-amnestic, CaMPDE inhibitor, activators of ubiquitin-mediated proteolysis, alpha-glucosidase inhibitor, immunomodulating, calcium-binding, antibacterial, anti-inflammatory, and hypotensive agent. Using the Database of Antimicrobial Activity and Structure of Peptides (DBAASP) prediction method, the antibacterial activity of the released peptides was predicted, highlighting the existence of potent antibacterial peptides. An examination of their physicochemical properties revealed that most peptides are low molecular weight, mildly acidic, and moderately water-soluble. To further establish the non-toxicity profile of the released peptides (sequence length > 3), a ToxinPred analysis was performed, which revealed that most of the peptides are non-toxic. According to the allergenicity analysis, most of the top-ranked peptides are likely non-allergenic.

Thus, our study reveals a less labor-intensive method for discovering new therapeutic targets derived from C. vulgaris, which hold both pharmacological and medical significance.

Reprogramming of lipid metabolism has emerged as a significant characteristic of malignancy during tumor development. Research indicates a critical link between lipid metabolism and the tumor immune microenvironment. This relationship not only facilitates cancer progression by remodeling the tumor microenvironment but also influences the functionality of immune cells. Alterations in lipid metabolism regulate the function and status of immune cells within the microenvironment, impacting immune evasion and the therapeutic efficacy of tumors. Consequently, targeting lipid metabolism is a viable strategy for intervening in tumorigenesis and tumor development. This review examines the roles of key lipid molecules, such as fatty acids and cholesterol, within the tumor microenvironment, highlighting how aberrant lipid metabolism can alter immune cell function. By investigating the interactions between lipid metabolism and immune cells in this setting, the review offers novel insights into early diagnosis, screening, and immunotherapy of malignant tumors. Furthermore, lipid metabolic reprogramming may act as a biomarker for monitoring early immune escape from tumors and predicting therapeutic outcomes, thereby enhancing early diagnosis and personalized cancer treatment.

The proto-oncogene c-Fos is known as a reliable marker of cell activation, which is immediately induced after a new stimulus in specific brain regions, depending on the nature of the stimulus applied. However, the expression of c-Fos is increased in Alzheimer’s disease (AD) and contributes to amyloid β-peptide-induced neurotoxicity. This review attempted to focus on the role of c-Fos in learning and memory in both healthy brain and AD, emphasizing on possible mechanisms. Comparing the available findings, regarding learning and memory, c-Fos expression leads to memory formation through ERK (extracellular signal-regulated kinase)/CREB (cAMP response element-binding protein) and long-term potentiation, while it is down regulated after the repetition and habituation of stimuli. However, its overexpression in neurons and glia of AD, contributes to cognitive deficits and neuronal loss, which represents a defect in its ability to habituate to repeated stimuli. Also, expression pattern in glial is associated with constitutive CREB activation following increasing amyloid beta (Aβ), activation transcription factor (ATF3), and cytochrome c in apoptosis pathways. Thus, two contradictory roles of c-Fos in the healthy brain and AD, reveal more complexity in c-Fos up and down stream signaling pathways, bioavailability, and sensitivity. Future studies focusing on c-Fos modulation, might offer promising strategies to mitigate cognitive decline in AD.

Atypical trigeminal neuralgia (ATN) is a chronic pain condition characterized by persistent facial pain that does not respond well to conventional medical treatments, often leading to significant impairment in quality of life. This study examined the clinical characteristics and surgical outcomes of microvascular decompression combined with nerve combing in patients with ATN.

We conducted a retrospective analysis of surgical techniques, clinical data, and treatment outcomes in 40 patients from January 2009 to January 2018. Pain levels and patient prognoses were assessed using the Visual Analog Scale and the Barrow Neurological Institute (BNI) pain score. Dynamic monitoring of arterial blood pressure was performed, and levels of total adrenaline, norepinephrine, and dopamine were measured before and during the nerve combing procedure.

During surgery, veins combined with arachnoid adhesions and arachnoid adhesions alone were observed compressing the trigeminal nerve in seven patients (17.50%) and 33 patients (82.50%), respectively. Immediate postoperative BNI scores indicated excellent outcomes (P = 2) in 30 patients (75.00%) and good outcomes (P = 3) in four patients (10.00%). Long-term postoperative BNI scores showed excellent outcomes (P = 2) in 25 patients (62.50%) and good outcomes (P = 3) in seven patients (17.50%). All patients experienced an increase in arterial blood pressure during nerve combing, and the mean levels of adrenaline and norepinephrine before combing showed significant improvement (P < 0.05).

Microvascular decompression combined with nerve combing achieves favorable results in treating ATN. Long-term trigeminal nerve compression and central sensitization may contribute to the etiology in these patients.
