Gastrointestinal complications are common in patients after ischemic stroke. Gastric motility is regulated by gastric pace-making activity (also called gastric myoelectrical activity (GMA)) and autonomic function. The aim of this study was to evaluate GMA, assessed by noninvasive electrogastrography (EGG), and autonomic function, measured via spectral analysis of heart rate variability derived from the electrocardiogram in patients with ischemic stroke.

EGG and electrocardiogram were simultaneously recorded in both fasting and postprandial states in 14 patients with ischemic stroke and 11 healthy controls. Multi-channel surface EGG was used to measure GMA, and autonomic function was evaluated by heart rate variability spectral analysis.

Compared to healthy subjects, patients with ischemic stroke, especially those with a modified Rankin scale ≥ 4, had impaired GMA in both fasting and postprandial states. This included a lower percentage of normal gastric slow waves (the basic rhythmic waves of GMA) and a higher percentage of tachygastria, bradygastria, or arrhythmia. Patients with ischemic stroke also showed a decrease in the dominant frequency and power of the gastric slow waves. Autonomic functions were altered in ischemic stroke patients with a modified Rankin scale ≥ 4, as reflected by increased sympathetic activity and reduced parasympathetic activity.

Gastric pace-making activity is impaired in patients with severe ischemic stroke, as evidenced by a reduced percentage of normal gastric slow waves and a lower frequency of gastric slow waves, likely due to impaired autonomic functions.

Colorectal cancer (CRC) is a type of cancer that originates in the colon or rectum from precancerous polyps, which can evolve into cancerous growths over time. This review aimed to provide a comprehensive analysis of CRC, its subtypes, clinical manifestations, point-of-care diagnostic approaches, and management strategies. The clinical presentation of CRC often includes symptoms such as blood in stool, changes in bowel habits, abdominal discomfort, weight loss, fatigue, a feeling of incomplete bowel emptying, and anemia. The identification of these signs prompts healthcare professionals to initiate diagnostic measures without delay. Point-of-care diagnosis plays a pivotal role in the early detection of CRC, employing screening tests such as stool tests and colonoscopies. These diagnostic modalities enable healthcare professionals to identify precancerous polyps or early-stage tumors, facilitating timely intervention and significantly improving treatment outcomes. Adherence to screening guidelines is crucial for the prevention and early detection of CRC. Despite advancements in screening and treatment options, there remains a crucial need for more specific, minimally invasive screening methods with minimal side effects. By improving current detection methods, a better screening approach for CRC can be developed. Recent advancements, including single-cell sequencing, spatial transcriptomics, and artificial intelligence integration, hold great promise for enhancing early diagnosis and advancing personalized treatment strategies. Moreover, a healthy lifestyle, including a balanced diet, regular exercise, no tobacco use, and limited alcohol consumption, can significantly lower the risk of CRC. By emphasizing the importance of lifestyle modifications, early screening, and timely intervention, healthcare professionals can significantly reduce the burden of CRC and improve patient outcomes.

This study investigates upper gastrointestinal tract (UGIT) involvement in patients with ulcerative colitis (UC), a condition traditionally considered limited to the colon. Although extra-colonic manifestations of UC are well recognized, UGIT issues have received less attention. This research aimed to document the clinical, endoscopic, and histopathological UGIT findings in adults with UC and assess their association with disease severity and extent.

This descriptive cross-sectional study was conducted at Ain Shams University over one year. A total of 78 UC patients underwent comprehensive clinical evaluations, including assessments of gastrointestinal complaints, medication history, disease progression, surgeries, and physical examinations. Endoscopic assessments of both the UGIT and colon were performed, accompanied by biopsies for histopathological analysis.

The study population had a mean age of 35.26 years, with a nearly equal gender distribution. Endoscopic findings revealed significant UGIT involvement: 64% of patients had esophagitis and/or gastroesophageal reflux disease, 93% had gastritis, and 80% had duodenitis. Histopathological findings showed notable inflammation, basal cell hyperplasia, and ulcerations in the esophagus, with 51.3% of patients exhibiting chronic gastritis and 38.5% testing positive for Helicobacter pylori infection. Statistical analysis demonstrated a strong association between colonic disease severity and UGIT endoscopic (p < 0.0001 and p < 0.001 in the esophagus and stomach, respectively) and histopathological (p < 0.004, p < 0.001, and p <0.005 in the esophagus, stomach, and duodenum, respectively) findings, particularly in patients with UGIT symptoms.

This study concludes that UGIT endoscopic and histopathological changes are prevalent among Egyptian UC patients, suggesting a significant link between UC and these UGIT findings.

Despite advancements in diagnostic and therapeutic strategies, hepatocellular carcinoma (HCC) remains a leading cause of cancer-related mortality. Antioxidant-1 (ATOX1) has been implicated in oncogenic processes across various cancer types; however, its specific role in HCC remains unclear. This study aimed to investigate the function of ATOX1 and its underlying molecular mechanisms in HCC.

Immunohistochemical analysis was conducted to assess ATOX1 expression in HCC tissues. Cell Counting Kit-8, colony formation, Transwell migration, flow cytometry, and reactive oxygen species (ROS) assays were employed to evaluate the malignant behaviors of tumor cells. A xenograft mouse model was employed to assess the effects of ATOX1 knockdown on tumor growth in vivo. DCAC50 treatment was performed to inhibit the copper transport function of ATOX1. RNA sequencing was conducted to explore the potential molecular mechanisms of ATOX1 in HCC.

ATOX1 expression was significantly elevated in HCC tumor tissues. ATOX1 promoted cell proliferation, colony formation, and migration. Knockdown of ATOX1 suppressed tumor growth in vivo. Mechanistically, ATOX1 activated c-Myb, and thus enhanced the malignant phenotype of HCC cells via activation of the PI3K/AKT signaling pathway. Additionally, ATOX1 reduced intracellular copper accumulation and inhibited ROS production and apoptosis. Inhibition of ATOX1 by DCAC50 decreased cell proliferation while increasing ROS levels and apoptosis in HCC cells. Notably, acetylcysteine reversed the reduction in c-Myb expression induced by ATOX1 knockdown.

ATOX1 may promote HCC carcinogenesis through the activation of the c-Myb/PI3K/AKT pathway and the inhibition of copper accumulation and oxidative stress.

The refusal of blood transfusions and blood derivatives compels surgeons to face clinical and ethical challenges. We reviewed our perioperative and long-term outcomes of Jehovah’s Witnesses undergoing colon cancer surgery to evaluate the feasibility of bloodless procedures.

We retrospectively analyzed data from patients with colon cancer and Jehovah’s Witnesses who underwent surgery between January 2014 and December 2023. A protocol was systematically followed to optimize hemoglobin levels and other parameters according to the Enhanced Recovery After Surgery guidelines.

Sixteen patients underwent colon surgery, with a median age of 69 years and an equal gender distribution. Thirty-seven and a half percent had preoperative anemia and were managed by a hematologist. All procedures were performed in accordance with oncological standards. Postoperative treatment included low molecular weight heparin, and hemoglobin levels temporarily decreased postoperatively. No blood transfusions were needed during hospitalization. Two patients required surgical intervention due to postoperative hemorrhage. Complications included anastomotic dehiscence and perforation, with an overall morbidity rate of 25% and no 90-day mortality.

This study highlights the challenges in managing patients who reject blood products during colon cancer surgeries; however, the outcomes show results comparable to those of the general population with appropriate protocols. Preoperative optimization is crucial to reduce blood loss. Treatment of postoperative hemorrhage requires a lower threshold for intervention due to limited alternatives to blood products. Despite the limitations of the study, the findings advocate for careful monitoring and intervention. Larger studies are needed to validate these findings and improve care for this group of patients.

Liquid biopsy (LB) represents a promising strategy for the early diagnosis and treatment of lung cancer. However, relying solely on single-biomarker immunohistochemistry for predictive purposes has shown limited efficacy, often leading to suboptimal responses in certain patients. LB provides a complementary or alternative approach to immunohistochemistry by aiding in the identification of patients better suited for immunotherapy, thereby improving treatment precision. This review highlights key LB targets, including circulating tumor cells, exosomes, and small protein molecules, and explores the predictive and prognostic value of LB in immunotherapy for lung cancer and other tumors. These biomarkers play complex and multifaceted roles in liquid biopsies. Consequently, researchers have developed numerous targeted detection methods to study and identify key factors among multiple biomarkers in lung cancer and other tumor diseases. In addition, the limitations and future directions of LB are examined, aiming to advance its clinical application and support the development of personalized and precise immunotherapy. The integration of LB with artificial intelligence holds significant clinical potential for guiding immunotherapy and advancing precision medicine in lung cancer and other tumors.

Gut dysbiosis has been reported in severe liver diseases. However, information on the impact of hepatitis E virus infection on the gut microbiota, and the association between enteric microbiota disturbances and acute hepatitis E (AHE), is limited, particularly in elderly patients with AHE (AHE-elderly). Our objective was to characterize the AHE-specific microbiome in elderly patients and evaluate its association with clinical outcomes.

Fecal samples and clinical data were collected from 58 AHE-elderly patients (46 self-healing cases, 12 non-self-healing cases) and 30 elderly patients with healthy controls (hereinafter referred to as HCs-elderly). Gut microbiota composition was analyzed using 16S rRNA gene sequencing. Bioinformatic analyses, including alpha diversity and STAMP, were performed. The predictive potential of Bacteroides fragilis was assessed using statistical analysis and receiver operating characteristic curves.

Alpha diversity indices showed no significant differences in microbial diversity between the AHE-elderly and HCs-elderly groups, nor between self-healing and non-self-healing groups among AHE-elderly patients. Nevertheless, a trend toward altered species richness was observed. In the AHE-elderly group, the relative abundance of Firmicutes, Lactobacillales, and Bacilli increased significantly. Meanwhile, compared with the self-healing group, Bacteroidetes were more abundant in the non-self-healing group. At the species level, Bacteroides fragilis was the most abundant in the non-self-healing group, significantly contributing to the divergence in gut microbiota between the two groups.

The relative abundance of Bacteroidetes significantly distinguished AHE-elderly patients from healthy controls and could more accurately predict recovery outcomes in elderly AHE patients. These findings suggest new strategies for preventing and managing AHE recurrence in the elderly patients.

This study investigates the potential of methyl eugenol (ME), a compound found in the essential oils of various plants, to inhibit oxidative stress and its impact on diseases associated with this process. ME has been shown to possess antioxidant properties and antiproliferative activity in several cancers. It also demonstrates neuroprotective potential in conditions such as Alzheimer’s disease and ischemic brain injury. The mechanism of action involves the activation of the nuclear factor erythroid 2-related factor 2, which facilitates the transcription of antioxidant genes and modulation of pathways such as AMP-activated protein kinase/glycogen synthase kinase 3 beta, thereby reducing the production of reactive oxygen species and pro-inflammatory cytokines. However, research has identified potential toxicological risks associated with ME, including hepatotoxicity and changes in the gut microbiota. These findings highlight the need for caution when considering prolonged exposure to this compound.

Breast cancer is one of the leading causes of mortality among women worldwide. Tumor necrosis factor α-induced protein 3-interacting protein 1 (TNIP1) is a ubiquitin-binding protein that is widely expressed, but its function in breast cancer cells remains unknown. This study aimed to elucidate the molecular mechanism of TNIP1 regulation in the proliferation and apoptosis of breast cancer cells.

A colony formation assay was conducted on MCF-7 and T47D cells stably transfected with TNIP1/cyclin G1 (CCNG1) short hairpin RNAs. Quantitative polymerase chain reaction was performed to assess the relative abundances of TNIP1, CCNG1, and cyclin D1 (CCND1) messenger RNAs. Immunoprecipitation and immunoblotting were used to detect the expression of TNIP1, CCNG1, CCND1, and related proteins. A dual-luciferase reporter assay was employed to explore the molecular mechanism of TNIP1 in signal transduction. Caspase activity in MCF-7 and T47D cells transfected with TNIP1 short hairpin RNAs was measured using the Caspase-Glo 3/7 assay.

Ablation of TNIP1 induced growth arrest in breast cancer cells. TNIP1 directly interacted with CCNG1, and TNIP1 knockdown increased the ubiquitination of CCNG1. CCNG1 knockdown also induced growth arrest in MCF-7 and T47D cells. Furthermore, TNIP1 knockdown activated the NF-κB pathway and induced apoptosis in these cells.

TNIP1 regulates the proliferation and apoptosis of breast cancer cells, suggesting that TNIP1 may serve as a potential biomarker for breast cancer.

Epileptogenesis involves complex mechanisms, including inflammation and apoptosis. Rosiglitazone, a peroxisome proliferator-activated receptor gamma agonist, possesses anti-inflammatory and neuroprotective properties. This study investigated whether rosiglitazone can prevent pentylenetetrazole (PTZ)-induced kindling in mice by modulating inflammatory cytokines and apoptosis pathways.

Male C57BL/6 mice (n = 8 per group) were assigned to sham, control, or rosiglitazone-treated groups. Kindling was induced with intraperitoneal PTZ (40 mg/kg) every 48 h for 17 days. Rosiglitazone (0.1 mg/kg) was administered 30 m before each PTZ injection. Seizure progression was monitored, and hippocampal tissues were analyzed via immunohistochemistry and Western blotting to assess cytokine levels (interleukin (IL)-10, IL-17A, tumor necrosis factor-alpha, interferon-gamma), caspase-3 activity, and glial fibrillary acidic protein expression.

Rosiglitazone significantly delayed seizure progression, reduced seizure scores, and lowered pro-inflammatory cytokine levels (IL-17A, tumor necrosis factor-alpha, interferon-gamma) while increasing IL-10. Immunohistochemical analysis revealed fewer caspase-3-positive cells and reduced glial fibrillary acidic protein expression in the treatment group compared to controls.

Rosiglitazone exerts neuroprotective effects in PTZ-induced kindling, likely through its anti-inflammatory and anti-apoptotic actions. These findings underscore its potential as a therapeutic agent for mitigating epileptogenesis, warranting further investigation in combination therapies and clinical trials.
