Krittanawong, Chayakrit; Wang, Yichen; Qadeer, Yusuf Kamran; Chen, Bing; Wang, Zhen; Al-Azzam, Fu'ad; Alam, Mahboob; Sharma, Samin; Jneid, Hani
It is well known that individuals with liver cirrhosis are considered at high risk for cardiac surgery, with an increased risk for morbidity and mortality as the liver disease progresses. In the last decade, there have been considerable advances in transcatheter aortic valve implantation (TAVI) as an alternative to surgical aortic valve replacement (SAVR) in individuals deemed to be at high risk for surgery. However, research surrounding TAVI in the setting of liver cirrhosis has not been as widely studied. In this national population-based cohort study, we evaluated the trends of mortality, complications, and healthcare utilization in liver cirrhotic patients undergoing TAVI, as well as analyzed the basic demographics of these individuals. We found that from 2011 to 2020, the amount of TAVI procedures conducted in cirrhotic patients was increasing annually, while mortality, procedural complications, and healthcare utilization trends in these cirrhotic patients undergoing TAVI decreased. Overall, TAVI does seem to be reasonable management for aortic stenosis patients with liver cirrhosis who need aortic valve replacement.

Clinical implications of combination proton pump inhibitor and triple therapies in patients with atrial fibrillation following percutaneous intervention: a guide for clinicians
Gries, Jacob J; Chen, Bing; Virk, Hafeez Ul Hassan; Khalid, Umair; Jneid, Hani; Birnbaum, Yochai; Lavie, Carl J; Krittanawong, Chayakrit
INTRODUCTION/UNASSIGNED:Patients on systemic oral anticoagulation with vitamin K antagonists (VKA) or non-vitamin K oral anticoagulants (NOAC) often require triple therapy following percutaneous coronary intervention, substantially increasing the risk of bleeding. Gastroprotective agents like proton pump inhibitors (PPI) are often employed to mitigate this risk, despite potential competitive inhibition between P2Y12-receptor inhibitors, NOACs, and VKAs. While the interactions and clinical outcomes of PPIs and DAPT have been frequently explored in literature, not many studies have evaluated the same outcomes for triple therapy. AREAS COVERED/UNASSIGNED:This comprehensive narrative review of three studies on PPIs and triple from the PubMed/MEDLINE database supplemented by 23 other relevant studies aims to use the available literature to analyze the potential interactions between PPIs and triple therapy while shedding light on their mechanisms, clinical implications, and areas for optimization. EXPERT OPINION/UNASSIGNED:If triple therapy is indicated following PCI, then patients at high-risk for bleeding may benefit from transition to apixaban and a PPI to lower the risk of gastrointestinal bleeding. More research is needed to determine the role of PPIs in triple therapies in prevention of gastrointestinal bleeding or potentiation of other adverse outcomes.

Boosting Immunogenicity of a Recombinant Mycobacterium smegmatis Strain via Zinc-Dependent Ribosomal Proteins
Singh, Shivani; Kanzin, David; Chavez, Sarah; Saavedra-Avila, Noemi Alejandra; Ng, Tony W; Lukose, Regy; Mayer, Oren; Kim, John; Chen, Bing; Chen, Mei; Porcelli, Steven A; Jacobs, William R; Tiwari, Sangeeta
Tuberculosis (TB) continues to be a major global health burden and kills over a million people annually. New immunization strategies are required for the development of an efficacious TB vaccine that can potentially induce sterilizing immunity. In this study, we first confirmed that a live vaccine strain of Mycobacterium smegmatis, previously designated as IKEPLUS, conferred a higher survival benefit than the Bacillus Calmette-Guerin (BCG) in a murine model of intravenous Mycobacterium tuberculosis (Mtb) infection. We have shown that there was a significant increase in the expression of the Rv0282 gene, which is encoded in the esx-3 locus, which played an important role in iron uptake when IKEPLUS was grown in both low zinc and iron-containing Sauton medium. We then confirmed using in vitro assays of biofilm formation that zinc plays a vital role in the growth and formation of M. smegmatis biofilms. IKEPLUS grown in low zinc media led to the better protection of mice after intravenous challenge with a very high dosage of Mtb. We also showed that various variants of IKEPLUS induced apoptotic cell-death of infected macrophages at a higher rate than wild-type M. smegmatis. We next attempted to determine if zinc containing ribosomal proteins such as rpmb2 could contribute to protective efficacy against Mtb infection. Since BCG has an established role in anti-mycobacterial efficacy, we boosted BCG vaccinated mice with rmpb2, but this did not lead to an increment in the protection mediated by BCG.

Revascularization Strategies for Acute and Chronic Mesenteric Ischemia: A Narrative Review
Gries, Jacob J; Sakamoto, Takashi; Chen, Bing; Virk, Hafeez Ul Hassan; Alam, Mahboob; Krittanawong, Chayakrit
UNLABELLED:Mesenteric ischemia is a challenging condition characterized by insufficient blood perfusion to the mesentery and, consequently, intestinal tissues that continues to perplex clinicians. Despite its low prevalence, the condition's variable clinical presentation and elusive radiographic diagnosis can delay life-saving interventions in the acute setting and deteriorate the quality of life of patients when left undiagnosed or misdiagnosed. PURPOSE/OBJECTIVE:Review and summarize recent diagnostic updates and emergent intervention strategies for acute and chronic mesenteric ischemia. METHODS:A narrative review of all relevant studies from January 2022 through September 2023. RESULTS:A total of 11 studies from MEDLINE, supplemented with 44 studies from Google Scholar, were included in the review. CONCLUSIONS:Both acute and chronic mesenteric ischemia propose diagnostic and therapeutic challenges for interventionalists. Computed tomographic angiography remains the diagnostic modality of choice for both. Open surgical intervention remains the gold standard for acute mesenteric ischemia, while endovascular techniques are preferred for chronic mesenteric ischemia.

Pro-Inflammatory Food, Gut Microbiota, and Cardiovascular and Pancreatic Diseases
Chen, Bing; Patel, Shriraj; Bao, Lingyu; Nadeem, Danial; Krittanawong, Chayakrit
Recent studies have shown that a pro-inflammatory diet and dysbiosis, especially a high level of trimethylamine-N-oxide (TMAO), are associated with various adverse health conditions. Cardiovascular diseases and pancreatic diseases are two major morbidities in the modern world. Through this narrative review, we aimed to summarize the association between a pro-inflammatory diet, gut microbiota, and cardiovascular and pancreatic diseases, along with their underlying mechanisms. Our review revealed that TMAO is associated with the development of cardiovascular diseases by promoting platelet aggregation, atherosclerotic plaque formation, and vascular inflammation. TMAO is also associated with the development of acute pancreatitis. The pro-inflammatory diet is associated with an increased risk of pancreatic cancer and cardiovascular diseases through mechanisms that include increasing TMAO levels, activating the lipopolysaccharides cascade, and the direct pro-inflammatory effect of certain nutrients. Meanwhile, an anti-inflammatory diet decreases the risk of cardiovascular diseases and pancreatic cancer.

Advancements in Revascularization Strategies for Acute Mesenteric Ischemia: A Comprehensive Review
Gries, Jacob J; Virk, Hafeez Ul Hassan; Chen, Bing; Sakamoto, Takashi; Alam, Mahboob; Krittanawong, Chayakrit
Even with modern advancements in the management of acute mesenteric ischemia over the past decade, morbidity and mortality remain high, and the best primary treatment modality is still debated amongst interventionalists. Traditionally, interventionalists have favored an open surgical approach but are now trending for endovascular interventions due to apparent reduced mortality and complications. Newer studies suggest hybrid approaches, and intestinal stroke centers may be superior to either strategy alone. This narrative review will explore the natural history of acute mesenteric ischemia with the aim of increasing interventionalist awareness of modern advancements in revascularization strategies for this devastating disease.

Heartburn's Hidden Impact: A Narrative Review Exploring Gastroesophageal Reflux Disease (GERD) as a Cardiovascular Disease Risk Factor
Gries, Jacob J; Chen, Bing; Virani, Salim S; Virk, Hafeez Ul Hassan; Jneid, Hani; Krittanawong, Chayakrit
Gastroesophageal reflux disease (GERD) is a very common disease with an estimated 442 million cases worldwide. It is a well-documented independent risk factor for many gastrointestinal pathologies, however, its role in cardiovascular disease (CVD) is unclear, despite its high prevalence in patients with CVD. Although traditionally considered a causative agent of noncardiac chest pain, a common imitator of cardiac chest pain, or an incidentally shared comorbidity in patients with CVD, a number of studies have implicated GERD and its therapies as risk factors for CVD. This narrative review will explore the relationship between GERD and CVD, including medical and mechanical therapeutic approaches for GERD that could potentially impact the incidence, progression, and mortality of CVD.

Association of Cardiovascular Disease and Pancreatitis: What Came First, the Chicken or the Egg?
Chen, Bing; Moin, Aleena; Virk, Hafeez Ul Hassan; Jneid, Hani; Virani, Salim S; Krittanawong, Chayakrit
(1) Background: Recent studies suggest an association between pancreatitis and cardiovascular disease. This article aims to review the available evidence linking cardiovascular disease with acute and chronic pancreatitis. (2) Methods: A comprehensive search was conducted on the PubMed/MEDLINE database from inception to April 2022 using Medical Subject Heading and keywords related to pancreatitis and cardiovascular disease. The search was limited to English-language literature involving human subjects, and various study types, including observational studies, case-control studies, cohort studies, and clinical trials, were screened for eligibility. Following data extraction, the authors conducted a narrative synthesis of the studies. (3) Results: Longitudinal studies indicate that a history of acute pancreatitis is associated with an increased risk of acute atherosclerotic cardiovascular disease and acute coronary syndrome. Elevated triglyceride levels (>2000 mg/dL) have a temporal relationship with acute pancreatitis. Cross-sectional studies have shown that acute pancreatitis is associated with cardiac injury during the acute phase. Based on longitudinal studies, chronic pancreatitis is associated with an increased risk of cerebrovascular diseases. However, data regarding the relationship between chronic pancreatitis and myocardial infarction are conflicting. (4) Conclusions: Based on the available evidence, having a history of acute pancreatitis appears to increase the risk of acute atherosclerotic cardiovascular disease. However, there is insufficient evidence to conclude whether chronic pancreatitis is associated with cardiovascular disease, and no definitive studies have yielded conflicting results.

Wang, Yichen; Huang, Xiaoquan; Cheryala, Mahesh; Aloysius, Mark; Zheng, Beishi; Yang, Keming; Chen, Bing; Fang, Qianqian; Chowdary, Sriram B; Abougergi, Marwan S; Chen, Shiyao
OBJECTIVES/OBJECTIVE:The US Preventive Services Task Force lowered the recommended starting age for colorectal cancer (CRC) screening in average-risk adults from 50 to 45 years. We aimed to estimate the global burden and trends of colorectal cancer in adults aged 20-49 years (early-onset CRC). METHODS:This is an analysis of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019). The GBD 2019 estimation methods were used to describe the incidence, mortality, and disability-adjusted life years (DALYs) of early CRC from 1990 to 2019. Data from 204 countries and geographic areas were available. RESULTS:The global incidence rate of early-onset CRC increased from 4.2/100 000 to 6.7/100 000 from 1990 to 2019. Mortality and DALYs of early-onset CRC also increased. The CRC incidence rate increased faster in younger adults (1.6%) than in adults aged 50-74 years (0.6%) as measured by the annual percentage change. The increase in early-onset CRC incidence was consistently observed in all five socio-demographic index (SDI) regions and 190 out of 204 countries and territories. Middle and high-middle SDI regions had faster annual increases in early-onset CRC, which warrants further attention. CONCLUSIONS:The global incidence, mortality, and DALYs of early-onset CRC increased from 1990 to 2019. The increase in early-onset CRC incidence was prevalent worldwide. Several countries were found to have higher incidence rates than the United States or fast increase in early-onset CRC, which warrants further attention.
