Colorectal cancer (CRC) has the highest mortality rate among men and is the second highest among women under fifty, with incidence and mortality rates rising in younger populations. Studies indicate that up to one-third of patients diagnosed before fifty have a family history or genetic factors, highlighting the need for earlier screening. Contrariwise, diagnosis in healthy subjects through screening strategies enables early-stage detection of the tumor and better clinical outcomes. In recent years, mortality rates of CRC in Western countries have been on a steady decline, which is largely attributed to widespread screening programs and advancements in treatment modalities. Indeed, early detection through screening significantly improves prognosis, with stark differences in survival rates between localized and metastatic disease. This article aims to provide a comprehensive review of the existing literature, delving into the performance and efficacy of various CRC screening strategies. It navigates through available screening tools, evaluating their efficacy and cost-effectiveness. The discussion extends to delineating target populations for screening, emphasizing the importance of tailored approaches for individuals at heightened risk.
Pancreatic cancer is one of the leading causes of cancer-related deaths worldwide. Pancreatic lesions consist of both neoplastic and non-neoplastic lesions and often pose a diagnostic and therapeutic challenge due to similar clinical and radiological features. In recent years, pancreatic lesions have been discovered more frequently as incidental findings due to the increased utilization and widespread availability of abdominal cross-sectional imaging. Therefore, it becomes imperative to establish an early and appropriate diagnosis with meticulous differentiation in an attempt to balance unnecessary treatment of benign pancreatic lesions and missing the opportunity for early intervention in malignant lesions. Endoscopic ultrasound (EUS) has become an important diagnostic modality for the identification and risk stratification of pancreatic lesions due to its ability to provide detailed imaging and acquisition of tissue samples for analysis with the help of fine-needle aspiration/biopsy. The recent development of EUS-based technology, including contrast-enhanced endoscopic ultrasound, real-time elastography–endoscopic ultrasound, miniature probe ultrasound, confocal laser endomicroscopy, and the application of artificial intelligence has significantly augmented the diagnostic accuracy of EUS as it enables better evaluation of the number, location, dimension, wall thickness, and contents of these lesions. This article provides a comprehensive overview of the role of the different types of EUS available for the diagnosis and differentiation of pancreatic cancer from other pancreatic lesions while discussing their key strengths and important limitations.

Worldwide, a majority of routine endoscopic procedures are performed under some form of sedation to maximize patient comfort. Propofol, benzodiazepines and opioids continue to be widely used. However, in recent years, Remimazolam is gaining immense popularity for procedural sedation in gastrointestinal (GI) endoscopy. It is an ultra-short-acting benzodiazepine sedative which was approved by the Food and Drug Administration in July 2020 for use in procedural sedation. Remimazolam has shown a favorable pharmacokinetic and pharmacodynamic profile in terms of its non-specific metabolism by tissue esterase, volume of distribution, total body clearance, and negligible drug-drug interactions. It also has satisfactory efficacy and has achieved high rates of successful sedation in GI endoscopy. Furthermore, studies have demonstrated that the efficacy of Remimazolam is non-inferior to Propofol, which is currently a gold standard for procedural sedation in most parts of the world. However, the use of Propofol is associated with hemodynamic instability and respiratory depression. In contrast, Remimazolam has lower incidence of these adverse effects intra-procedurally and hence, may provide a safer alternative to Propofol in procedural sedation. In this comprehensive narrative review, highlight the pharmacologic characteristics, efficacy, and safety of Remimazolam for procedural sedation. We also discuss the potential of Remimazolam as a suitable alternative and how it can shape the future of procedural sedation in gastroenterology.
Background: Sex-related treatment disparities are well-documented across various medical conditions, yet their impact on the management of inflammatory bowel disease (IBD) remains underexplored. This study aims to investigate sex-based differences in the management of ulcerative colitis (UC), focusing on both medical and surgical approaches and examining whether biological sex correlates with variations in healthcare utilization. Methods: A systematic search was conducted across multiple databases, including MEDLINE (via PubMed), Google Scholar, the Cochrane Library, and ScienceDirect, to identify studies on sex differences in ulcerative colitis (UC) management up to April 2024. Statistical analysis was performed using RevMan 5.4, with a random-effects model to combine odds ratios (OR) for both primary and secondary outcomes. The study is registered with PROSPERO (CRD42024537750). Results: The meta-analysis included eight observational studies involving 47,089 patients (51.9% females). There were no statistically significant sex differences in biologic therapy use (OR 0.89, 95% CI: 0.69 to 1.15, p = 0.36) or corticosteroid use (OR 1.17, 95% CI: 0.89 to 1.54, p = 0.27). However, females were less likely to use immunomodulators compared to males (OR 0.89, 95% CI: 0.85 to 0.94, p < 0.0001). There were no significant differences in surgical interventions, including total abdominal colectomy. Females had higher annual UC-related hospitalizations compared to males (OR 1.41, 95% CI: 1.22 to 1.64, p < 0.00001). Conclusions: In conclusion, while biologic and surgical treatments showed no significant sex differences, disparities were noted in immunomodulator use and hospitalization rates, underscoring the need for sex-specific UC management strategies.
Cholestasis due to sepsis is commonly seen in critically ill patients; however, it is often overlooked and poses a challenge in clinical diagnosis and management. In this report, we present a 29-year-old woman who presented to the emergency department with jaundice and symptoms of a urinary tract infection. Initially suspected to be Dubin-Johnson syndrome, sepsis-induced cholestasis was eventually diagnosed after testing. Sepsis should always be considered as part of the differential diagnosis while managing a patient with jaundice. The management of sepsis-induced cholestasis involves treating the underlying infection. In most cases, liver injury improves with the resolution of the infectious process.
Pancreatic cancer is a rare but lethal cancer due to its biologically aggressive nature, advanced stage at the time of diagnosis, and poor response to oncologic therapies. The risk of pancreatic cancer is significantly higher to 5% in certain high-risk individuals with inherited genetic susceptibility. Screening for pancreatic cancer in these individuals from high-risk groups can help with the early detection of pancreatic cancer as well as the detection of precursor lesions leading to early surgical resection and improved overall outcomes. The advancements in radiological imaging as well as advanced endoscopic procedures has made a significant impact on the early diagnosis, surveillance, and staging of pancreatic cancer. There is also a significant advancement in the development of biomarkers for the early detection of pancreatic cancer, which has also led to the development of liquid biopsy, allowing for microRNA detection in serum and circulating tumor cells. Various societies and organizations have provided guidelines for pancreatic cancer screening and surveillance in high-risk individuals. In this review, we aim to discuss the hereditary risk factors for developing pancreatic cancer, summarize the screening recommendations by different societies, and discuss the development of novel biomarkers and areas for future research in pancreatic cancer screening for high-risk individuals.
