Liquid Biopsy in Hepatocellular Carcinoma: The Significance of Circulating Tumor Cells in Diagnosis, Prognosis, and Treatment Monitoring.

Hepatocellular carcinoma (HCC) is an aggressive malignancy with poor outcomes when diagnosed at an advanced stage. Current curative treatments are most effective in early-stage HCC, highlighting the importance of early diagnosis and intervention. However, existing diagnostic methods, such as radiological imaging, alpha-fetoprotein (AFP) testing, and biopsy, have limitations that hinder early diagnosis. AFP elevation is absent in a significant portion of tumors, and imaging may have low sensitivity for smaller tumors or in the presence of cirrhosis. Additionally, as our understanding of the molecular pathogenesis of HCC grows, there is an increasing need for molecular information about the tumors. Biopsy, although informative, is invasive and may not always be feasible depending on tumor location. In this context, liquid biopsy technology has emerged as a promising approach for early diagnosis, enabling molecular characterization and genetic profiling of tumors. This technique involves analyzing circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), or tumor-derived exosomes. CTCs are cancer cells shed from the primary tumor or metastatic sites and circulate in the bloodstream. Their presence not only allows for early detection but also provides insights into tumor metastasis and recurrence. By detecting CTCs in peripheral blood, real-time tumor-related information at the DNA, RNA, and protein levels can be obtained. This article provides an overview of CTCs and explores their clinical significance for early detection, prognosis, treatment selection, and monitoring treatment response in HCC, citing relevant literature.

Increasing Pancreatic Cancer Incidence in Young Women in the United States: A Population-Based Time-Trend Analysis, 2001-2018.

BACKGROUND & AIMS: Previous studies have shown an increasing incidence of pancreatic cancer (PC), especially in younger women; however, this has not been externally validated. In addition, there are limited data about contributing factors to this trend. We report age and sex-specific time-trend analysis of PC age-adjusted incidence rates (aIRs) using the National Program of Cancer Registries database without Surveillance Epidemiology and End Results data. METHODS: PC aIR, mortality rates, annual percentage change, and average annual percentage change (AAPC) were calculated and assessed for parallelism and identicalness. Age-specific analyses were conducted in older (≥55 years) and younger (<55 years) adults. PC incidence based on demographics, tumor characteristics, and mortality were evaluated in younger adults. RESULTS: A total of 454,611 patients were diagnosed with PC between 2001 and 2018 with significantly increasing aIR in women (AAPC = 1.27%) and men (AAPC = 1.14%) without a difference (P = .37). Similar results were seen in older adults. However, in younger adults (53,051 cases; 42.9% women), women experienced a greater increase in aIR than men (AAPCs = 2.36%, P < .001 vs 0.62%, P = 0.62) with nonparallel trends (P < .001) and AAPC difference of 1.74% (P < .001). This AAPC difference appears to be due to rising aIR in Blacks (2.23%; P < .001), adenocarcinoma histopathologic subtype (0.89%; P = .003), and location in the head-of-pancreas (1.64%; P < .001). PC mortality was found to be unchanged in women but decreasing in counterpart men (AAPC difference = 0.54%; P = .001). CONCLUSION: Using nationwide data, covering ≈64.5% of the U.S. population, we externally validate a rapidly increasing aIR of PC in younger women. There was a big separation of the incidence trend between women and men aged 15-34 years between 2001 and 2018 (>200% difference), and it did not show slowing down.

Safety and Efficacy of Fully Covered Self-Expandable Metal Stents for Benign Upper Gastrointestinal Strictures Beyond the Esophagus.

Background Stents utilized for pyloric, duodenal, or anastomotic malignant strictures are generally uncovered and are not retrievable. Taewoong Medical created a through-the-scope stent that is fully covered, retrievable, and can be placed beyond the esophagus for benign gastroduodenal strictures as an alternative to surgical approaches. The aim of this paper is to examine the safety and efficacy of short-term, fully covered, self-expanding metal stents (FC-SEMS) in refractory benign strictures of the pylorus, duodenum, and gastrojejunal anastomosis. Methodology This multicenter case series was conducted at four hospitals from January 2018 through December 2020. Patients presenting with benign strictures of the pylorus, duodenum, or gastrojejunal anastomosis were entered into the study. A therapeutic channel scope was utilized to place FC-SEMS to open strictures. The stents were removed a few weeks later. A four-point gastric outlet obstruction scoring system (GOOSS) was used to record improvement. Results Statistically significant improvement in GOOSS was found between the pre-procedure and the four-week follow-up. Conclusions Fully covered, retrievable metal stents appear safe and effective in the management of refractory benign pyloric, duodenal, and anastomotic strictures. This may provide a less invasive option in the management of these strictures compared to surgery.

Utilization of Antireflux Mucosectomy and Resection and Plication: A Novel Approach for the Management of Recurrent Gastroesophageal Reflux Disease after Prior Nissen Fundoplication or Transoral Incisionless Fundoplication.

Background: Nissen Fundoplication (NF) and Transoral Incisionless Fundoplication (TIF) are established procedures for the treatment of gastroesophageal reflux disease (GERD). However, the surgically induced plication can loosen over time. This multicenter study aims to evaluate the safety and efficacy of Antireflux Mucosectomy (ARMS) and Resection and Plication (RAP) in symptomatic patients with prior NF or TIF that has become loose. Patients and methods: Eighteen patients were enrolled in the study. Ten had prior TIF, while eight had prior NF. Half of these patients had a Hill Grade 3 Valve while the other half had a Hill Grade 2 valve. Endoscopic submucosal dissection (ESD) was performed in six patients, while endoscopic mucosal resection (EMR) was performed in twelve patients. A follow-up endoscopy was performed at 4-12 weeks. Results: At follow-up, 11 patients had a Hill Grade 1 valve, and seven patients had a Hill Grade 2 valve. All patients had improvement in symptoms for up to 32 months. Conclusions: In this pilot study, ARMS/RAP appears to be an effective option in patients who had prior NF or TIF with recurrent GERD symptoms.

Endoscopic Ultrasound-Guided Botox Injection for Refractory Anal Fissure.

Background: Anal fissures cause severe pain and can be difficult to treat. Medical therapy is initially used, followed by sigmoidoscopy-guided botox injections if the medical therapy is not successful. With this technique, however, it is not clear whether botox is injected into the muscle layer or submucosa. Aim: To evaluate the efficacy of EUS-guided botox injection directly into the internal sphincter. Methods: Consecutive patients with chronic anal fissure refractory to conventional endoscopic botulinum toxin type A injection were enrolled in the study. EUS was performed using a linear array echoendoscope, and a 25 G needle was used to inject botox. All patients were followed up at one- and two-month intervals. Results: Eight patients with chronic anal fissures were included in the study. Six patients had an excellent response to botox at the two-month interval using a visual analog pain scale, while one patient had a moderate response with a pain score reduction of 40%. One patient had no response. No complications were noted. An improvement in visual analog scale (pre-score > post-score) was statistically significant at the p < 0.01 level. Conclusion: EUS-guided botox injection into the internal sphincter appears to be a promising technique for patients with refractory anal fissure with pain.

Missed at Birth: A Rare Case of Acute Pancreatitis Secondary to Congenital Diaphragmatic Hernia.

Acute pancreatitis is a common gastrointestinal cause of hospitalizations across the world. The most common etiologies of acute pancreatitis include gallstones, excessive alcohol use, hypertriglyceridemia, or, rarely, trauma. Traction-induced pancreatitis is an uncommon but previously reported cause of acute pancreatitis. We present a 60-year-old male with a past medical history of cerebral palsy who presented to our facility with acute pancreatitis secondary to a congenital diaphragmatic hernia.

The Pain of Staying Alert: A Case Report and Literature Review on Energy Drink-Induced Acute Pancreatitis.

Energy drink consumption has increased over the past decade. It is associated with several common side effects including diarrhea, heartburn, and dyspepsia. Energy drinks have been proposed as a rare but potential cause of acute pancreatitis. This paper investigates a unique case of energy drink-induced pancreatitis and further explores current literature on this topic. This study stresses the importance of asking all patients presenting with acute pancreatitis about their daily energy drink consumption, especially if the cause is unknown.

Bone Marrow Suppression Secondary to the COVID-19 Booster Vaccine: A Case Report.

As of September 2021, SARS-CoV-2 booster shots became widely available in the US to ensure continued protection against the virus. A temporal relationship has been previously reported between the first or second dose of the COVID-19 vaccine and the development of thrombocytopenia. However, adverse events related to the third COVID-19 vaccine are still being reported and studied. We report a 74-year-old male who developed bone marrow suppression and pancytopenia recorded seven days after receiving the Pfizer SARS-CoV-2 vaccine. During his hospital stay, the patient's hemoglobin, white blood cell, and platelet levels continued to trend downwards. However, all three levels showed improvement one week after discharge without robust intervention. Global vaccination is of utmost importance, as is understanding and documenting post-vaccination reactions including bone marrow suppression. Prompt evaluation and patient education are imperative to improve patient outcomes and combat hesitancy against vaccine administration.

Initial Presentation of Cirrhosis Mimicking an Ischemic Stroke.

Liver cirrhosis is the 12th most common cause of death in the United States of America. This disease commonly presents with neurological disorders including, but not limited to, dementia, asterixis or coma. Hepatic encephalopathy and hyperammonemia are suspected to be the cause of altered mentation. However, hepatic encephalopathy with neurological symptoms mimicking stroke is underestimated. We present a case of liver cirrhosis manifesting with initial signs of right-sided hemiparesis.

Pilot evaluation of obesity-specific health-related quality of life following a 12-week non-randomized lifestyle intervention in youth.

BACKGROUND: Health-related quality of life (HRQOL), a multifaceted construct for understanding health and healthcare outcomes, is comprised of eight domains of well-being and functioning over time and has become an essential factor in assessing outcomes for youth with obesity. AIMS: To evaluate the effect of a community based, lifestyle intervention, on obesity-specific HRQOL using the Sizing Me Up (SMU) in this group of Latino and White youth. MATERIALS AND METHODS: For this 12-week family and community-based intervention (ACT; Actively Changing Together), HRQOL was measured before and after the intervention concluded using the obesity-specific HRQOL tool, SMU. This study enrolled 68 youth (10.9 ± 2 years; 54% male; 50% non-Hispanic white). Paired t-tests were used to examine the Sizing Me Up sub-scales: Emotion, Physical, Social Avoidance, Positive Attributes, Teasing, and the total score. A greater change score indicated a larger increase in quality of life sub-scale. RESULTS: Significant improvements from baseline to follow-up were found in the total SMU (mean change = 5.27, SD 10.76, p = 0.00) and for the sub-scores of: emotion (mean change = 8.06, SD 16.85, p ≤ 0.00), teasing (mean change = 5.65, SD 16.79, p = 0.01), and social avoidance (mean change = 3.92, SD 11.21, p = 0.01). CONCLUSIONS: Sizing Me Up provided a clinically meaningful tool for this research study to evaluate obesity-specific HRQOL among Hispanic and non-Hispanic White youth with obesity.
