Impact of moderate sedation on electrophysiology lab time for left atrial appendage occlusion using 4D-intracardiac echocardiography.

INTRODUCTION: Left atrial appendage occlusion (LAAO) can be performed using diverse anesthetic approaches ranging from moderate sedation (MS) to general anesthesia (GA), and guided by intracardiac echocardiography (ICE) or transesophageal echocardiography (TEE). Prior studies have demonstrated shorter time in lab for heart rhythm procedures performed under MS. The objective of this study was to compare laboratory times, acute procedural outcomes and complication rates for LAAO procedures performed using MS and 4-dimensional ICE as opposed to GA. METHODS AND RESULTS: This was a retrospective observational cohort study of 135 consecutive patients who were referred for LAAO to be performed with either GA or MS between June 2022 and April 2024. The primary endpoints were total laboratory time, procedure time, nonprocedure time, and fluoroscopy time. The secondary endpoints were stroke, peri-device leak (>5 mm), device-related left atrial thrombus, cardiovascular mortality, and all-cause mortality at 45 days and 6 months postprocedure, where data were available. The mean age of patients in the study was 78.8 ± 7.8 years and 64.4% were male with no difference between GA and MS. In the MS group, 4D-ICE was used for intraprocedural imaging in 95.5% of patients and 2 dimensional-ICE (2D-ICE) was used in 4.5% of patients. In the GA group, intra-procedural imaging was done using TEE in 51.5%, 2D-ICE in 32.4% and 4D-ICE in 16.2% of cases. Total laboratory time was significantly lower in the MS group compared to the GA group (68.3 ± 23.1 vs 117.1 ± 34.3 min; p < 0.001), due to shorter nonprocedure time (15.2 ± 9.1 vs 63.7 ± 22.0 min; p < 0.001), with no significant difference in procedure time and fluoroscopy time. There was no significant difference in complications at 45 days and 6 months postprocedure. CONCLUSION: In this single center study, MS reduced total lab time by reducing nonprocedure time when compared to GA for LAAO, without affecting clinical outcomes.

The efficacy of bone marrow mononuclear stem cell transplantation in patients with non-ischemic dilated cardiomyopathy-a meta analysis.

Cardiomyopathy refers to a wide spectrum of heart pathologies that interfere with normal heart function. Management options of patients with cardiomyopathy depended mainly on the severity of the condition. Lifestyle modifications and regular exercise together with a healthy diet is compatible for mild conditions. Severe conditions, however, rely on medications or surgery. Here, we aim to investigate the efficacy of bone marrow mononuclear stem cell transplantation in patients with dilated cardiomyopathy. We searched PubMed, Scopus, and Cochrane CENTRAL for relevant clinical trials and excluded observational studies. We performed the quality assessment of this study following GRADE guidelines. The assessment of the risk of bias was performed by the Cochrane's risk of bias tool. We present an analysis of the following outcomes: left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and six minutes walking test. Data were pooled as mean differences (MD) and relative confidence intervals (CI). The analysis of 667 patients from 11 studies receiving autologous bone marrow cell therapy for non-ischemic dilated cardiomyopathy is presented. A total of 338 patients were allocated to the treatment group, and 329 participants entered the control group. The mean age of the patients in the treatment group is 52.4 ± 4.3 years, while that of the control is 53.7 ± 3.7 years. Seven studies (14.18-23) reported transplantation through the intracoronary route. Table 1 shows a summary of the baseline characteristics of the included studies and participants, the number of injected cells, and the type of injected cells in each trial. Table 2 summarizes and illustrates the previous treatment history of included patients in each trial, as well as the baseline values of different scores used as outcome measures in this analysis. We found that bone marrow mononuclear stem cell therapy leads to significantly increased LVEF (MD = 4.54%, 95% CI [3.52, 5.56], P < 0.0001). Patients in the transplant group experienced less left ventricular end-diastolic diameter (millimeter) than the control arm (MD = -1.86 mm, 95% CI [-4.01, 0.29], P = 0.09). Additionally, Patients in the transplant group could walk 28.53 m more than the controls (MD = 28.53 m, 95% CI [2.51, 54.55], P = 0.03). Transplantation of bone marrow stem cells yields acceptable results regarding left ventricular ejection fraction and lowers the left ventricular end-diastolic diameter. Additionally, the six minutes walking test is improved in the transplant group.

Electrocardiographic abnormalities in patients with metabolic dysfunction-associated steatotic liver disease: A systematic review and meta-analysis.

INTRODUCTION: This study review aimed to consolidate current knowledge on the electrocardiographic abnormalities observed in patients with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), formerly known as Non-Alcoholic Fatty Liver Disease (NAFLD). METHODS: This was a systematic review of studies on the association between MASLD and electrocardiographic abnormalities, published between January 1, 1946, and October 31, 2023. Data from eligible studies were extracted, analyzed, synthesized, and summarized. RESULTS: We evaluated a total of 27 studies with 8,607,500 participants overall and 1,005,101 participants with MASLD. There was a statistically significant association between MASLD and prevalent atrial fibrillation (pooled OR: 1.34 95 % CI: 1.20-1.49, p < 0.001, n = 12), shorter QRS duration (pooled SMD: -0.073, 95 % CI: -0.144 - -0.001, n = 2, p = 0.048, n = 2), QTc prolongation (p < 0.001, n = 2), LVH (pooled OR: 1.48, 95 % CI: 1.25-1.75, p < 0.001, n = 3), low voltage (p < 0.001, n = 1), ST changes (OR: 1.41, 95 % CI: 1.04-1.91, p = 0.027, n = 1), T wave inversion (p < 0.001, n = 1), axis deviation (OR: 3.21, 95 % CI: 1.99-5.17, p < 0.001, n = 1), conduction defect (OR: 2.79, 95 % CI: 1.83-4.26, p < 0.001, n = 1) and bundle branch block (OR: 2.90, 95 % CI: 1.82-4.61, p < 0.001, n = 1), any persistent heart block (p < 0.001, n = 1), fragmented QRS (p < 0.001, n = 1), and p wave dispersion (p < 0.001, n = 1) CONCLUSION: MASLD is associated with multiple ECG abnormalities which are potential markers of early cardiac involvement, highlighting the multisystemic nature of MASLD. These specific ECG abnormalities could be used in screening and management algorithms to improve cardiac risk stratification in MASLD patients. PROSPERO REGISTRATION: CRD42023477501.

Association of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) With an Increased Risk of Congestive Heart Failure in Hospitalized Patients With Cirrhosis: A Propensity Score-Matched Analysis.

INTRODUCTION: Metabolic dysfunction-associated steatotic liver disease (MASLD) is linked to increased cardiovascular (CV) risks, notably congestive heart failure (CHF). We evaluated the influence of MASLD on CHF and mortality among hospitalized cirrhotic patients. METHODS: We analyzed the National Inpatient Sample from 2016 to 2020, identifying adult cirrhosis patients. We focused on CHF and in-hospital mortality, plus hospital stay length, costs, and discharge status. Propensity score matching created balanced cohorts for comparison. Poisson and logistic regression provided adjusted CHF risks and mortality odds ratios (ORs) for MASLD patients. RESULTS: Before matching, 4.1% of 672,625 cirrhotic patients had MASLD. Post-matching, each group had 23,161 patients. Patients with MASLD showed higher CHF risk (OR 1.14, 95% CI 1.10-1.21, p<0.001) but lower in-hospital mortality (OR 0.57, 95% CI 0.52-0.63, p<0.01) and decreased costs (median $24,447 vs. $28,630, OR 0.86, 95% CI 0.85-0.87, p<0.001). CONCLUSION: In this nationwide study of patients with cirrhosis, MASLD was associated with a higher prevalence of CHF and lower in-patient mortality. These findings mirror the "adiposity paradox" phenomenon, where obese/overweight individuals with cardiometabolic dysfunction may experience less severe or beneficial health outcomes than those with a normal weight. Further investigation is warranted to decode the intricate interplay between MASLD, cirrhosis, CHF, and in-hospital mortality and its clinical practice implications.

A systematic review and meta-analysis of left atrial strain in hypertrophic cardiomyopathy and its prognostic utility.

Despite advances in noninvasive imaging modalities to identify atrial fibrillation (AF) risk in Hypertrophic Cardiomyopathy (HCM), there is a paucity of evidence concerning the impact of low Left Atrial strain (LAS) on AF and major adverse cardiac events (MACE) incidence in these patients. This study investigated the diagnostic and prognostic significance of LAS in predicting AF and MACE in HCM. Findings revealed lower LA reservoir (MD: -11.79, 95% CI -14.83, -8.74; p<0.00001), booster (MD: -4.10, 95% CI -6.29, -1.91; p=0.0002), and conduit (MD: -7.52, 95% CI -9.39, -5.65; p<0.00001) strains in HCM patients versus healthy controls, and also indicated a significant association between low LA reservoir/conduit/booster strain and the development of new AF as well as MACE prevalence in HCM patients. The results from this study suggest the valuable role of LA strain in HCM and its utility in predicting the development of new AF and cardiac events in HCM patients.

Cardiovascular morbidity and mortality in lean vs. non-lean MASLD: A comprehensive meta-analysis.

BACKGROUND: Lean metabolic dysfunction-associated steatotic liver disease (MASLD), characterized by a BMI < 25 kg/m² (or < 23 kg/m² in Asians), presents a challenging prognosis compared to non-lean MASLD. This study examines cardiovascular outcomes in both lean and non-lean MASLD cohorts. METHODS: In this meta-analysis, pooled odds ratios (ORs) within 95 % confidence intervals (CIs) were calculated for primary outcomes (cardiovascular mortality and major adverse cardiovascular events [MACE]) and secondary outcomes (cardiovascular disease [CVD], all-cause mortality, hypertension, and dyslipidemia). Studies comparing lean and non-lean MASLD within the same cohorts were analyzed, prioritizing those with larger sample sizes or recent publication dates. RESULTS: Twenty-one studies were identified, encompassing lean MASLD patients (n = 7153; mean age 52.9 ± 7.4; 56 % male) and non-lean MASLD patients (n = 23,514; mean age 53.2 ± 6.8; 63 % male). Lean MASLD exhibited a 50 % increase in cardiovascular mortality odds compared to non-lean MASLD (OR: 1.5, 95 % CI 1.2-1.8; p < 0.0001). MACE odds were 10 % lower in lean MASLD (OR: 0.9, 95 % CI 0.7-1.2; p = 0.7), while CVD odds were 40 % lower (p = 0.01). All-cause mortality showed a 40 % higher odds in lean MASLD versus non-lean MASLD (p = 0.06). Lean MASLD had 30 % lower odds for both hypertension (p = 0.01) and dyslipidemia (p = 0.02) compared to non-lean MASLD. CONCLUSION: Despite a favorable cardiometabolic profile and comparable MACE rates, lean individuals with MASLD face elevated cardiovascular mortality risk.

Temporal trends and procedural safety of transcatheter mitral valve repair with mitraclip in patients with hypertrophic cardiomyopathy: Insights from the national inpatient sample.

Data on utilization and safety of mitral Transcatheter Edge-to-Edge Repair (TEER) among hypertrophic cardiomyopathy (HCM) patients is limited. Our study aimed to assess the national utilization, safety, and clinical outcomes of TEER procedures among HCM patients using a nationwide real-world cohort. HCM patients undergoing TEER hospitalizations between 2015-2020 were identified using ICD-10 (International Classification of Diseases, (ICD-10-CM/PCS). HCM-TEER and HCM No-TEER formed the two comparison groups. Demographic characteristics, baseline comorbidities, procedural complications, inpatient mortality, length of stay (LOS), and cost of hospitalization were compared between the propensity-matched cohorts. Numeric values of 10 or less were not reported per NIS data use agreements. A total of 39,625 weighted cases of TEER were identified from 2015-2020. Of the included patients, 335 patients had the HCM diagnosis. The median age of the HCM-TEER group was 74 (70-79) vs. 79 (72-85) for the no-TEER cohort. The TEER procedure was more frequently performed among Caucasians (86.57%) and females (53.73%). The TEER procedure among HCM patients had similar in-hospital mortality (Adjusted odds ratio: aOR 1.50, 95% CI [0.68-3.29]; p = 0.30) and net adverse cardiac events (NACE) (aOR 1.16, 95% CI [0.73-1.85]; p = 0.51). TEER among HCM was associated with higher odds of gastrointestinal/hematological (aOR 2.33, 95% CI [1.29-4.19]; p = 0.003) complications. However, the odds of cardiac complications (aOR 0.57, 95% CI [0.33-0.96]; p = 0.03) were not higher. The median length of stay was similar in both the groups (median: 2 vs. 2, p = 0.74), although TEER among HCM was associated with higher costs of hospitalization ($44729.36 vs. $40513.82, p < 0.01). TEER is a minimally invasive procedure and could be a safe option for symptomatic HCM patients with significant MR who are poor surgical candidates. Mitral TEER among HCM has been increasingly utilized in recent years in the United States more commonly in obstructive HCM and is associated with no difference in mortality and net adverse cardiac events but higher odds for gastrointestinal/hematological complications than non-HCM patients.

Point-of-Care Ultrasound Overview and Curriculum Implementation in Internal Medicine Residency Training Programs in the United States.

Point-of-care ultrasonography (POCUS) augments physical examination and expedites diagnostic care and clinical decision-making. The use of POCUS in internal medicine (IM) appears inconsistent despite its commendable benefits. It is not fully incorporated into the IM residency core competency skills or academic curriculum. This narrative literature review explores the benefits of POCUS and evaluates the need for an IM-focused POCUS curriculum. The obstacles and a proposed curriculum are also described.

Congenital Long QT Syndrome, Coinciding With Cavitary Mycobacterium avium Lung Infection, Led to Cardiac Arrest.

Congenital long QT syndrome is a cardiac disorder leading to arrhythmias and sudden cardiac death. We present a case of a 55-year-old woman with altered mental status experiencing cardiac arrest caused by congenital long QT syndrome, coincidentally found with Mycobacterium avium complex lung infection. Genetic testing identified a pathogenic mutation in the KCNH2 gene. (Level of Difficulty: Intermediate.).

Meta-Analysis Comparing Outcomes of Remote Hemodynamic Assessment Versus Standard Care in Patients With Heart Failure.

In patients with congestive heart failure (CHF), remote hemodynamic monitoring can reduce heart failure exacerbation and mortality. In this study, we compared the effectiveness of remote hemodynamic monitoring with that of standard care in the management of patients with CHF. The remote monitoring group included 7,733 patients, and the control group included 7,567 patients. Chi-square test and I-square statistics were used to assess heterogeneity. Risk ratios (RRs) were calculated using fixed-effects and random-effects methods to determine the risk of all-cause hospitalization and CHF-related hospitalization (primary outcomes) and all-cause mortality and device outcomes (secondary outcomes). Pooled findings indicated a 7% lower risk of all-cause hospitalization in the remote monitoring group than that in the control group (RR 0.93, 95% confidence interval [CI] 0.89 to 0.98, p = 0.004). The results also revealed a 32% lower risk of CHF-related hospitalization in the remote monitoring group than that in the control group (RR 0.68, 95% CI 0.65 to 0.71, p <0.001). No statistically significant differences were noted between the groups in terms of all-cause mortality (RR 0.97, 95% CI 0.87 to 1.07, p = 0.53) and device outcomes (RR 1.23 95% CI 0.92 to 1.65, p = 0.16). These results provided evidence regarding the comparable effectiveness of remote CHF monitoring and routine care. The current evidence is insufficient to introduce remote hemodynamic CHF monitoring; however, our results suggest that the integration of telemonitoring systems with routine medical management may improve heart failure care.

Incidence and risk factors of cardiovascular mortality in patients with gastrointestinal adenocarcinoma.

BACKGROUND: Gastrointestinal (GI) cancers are common and fatal. Improved cancer-directed therapies, with thier substantial role in improving cancer-specific survival, may increase non-cancer mortality-including cardiovascular mortality-in these patients. AIM: To identify the risk factors of cardiovascular mortality in GI adenocarcinoma patients. METHODS: Data of GI adenocarcinoma patients were gathered from the Surveillance, Epidemiology, and End Results database. We used Pearson's chi-square test to assess the relationships between categorical variables. We used the Kaplan-Meyer test in the univariate analysis and Cox regression test for the multivariate analysis. RESULTS: Among 556,350 included patients, 275,118 (49.6%) died due to adenocarcinoma, 64,079 (11.5%) died due to cardiovascular causes, and 83,161 (14.9%) died due to other causes. Higher rates of cardiovascular mortality were found in patients ≥ 50 years (HR, 8.476; 95% CI, 7.91-9.083), separated (HR, 1.27; 95% CI, 1.184-1.361) and widowed (HR, 1.867; 95% CI, 1.812-1.924), patients with gastric (HR, 1.18; 95% CI, 1.1-1.265) or colorectal AC (HR, 1.123; 95% CI, 1.053-1.198), and patients not undergone surgery (HR, 2.04; 95% CI, 1.958-2.126). Lower risk patients include females (HR, 0.729; 95% CI, 0.717-0.742), blacks (HR, 0.95; 95% CI, 0.924-0.978), married (HR, 0.77; 95% CI, 0.749-0.792), divorced (HR, 0.841; 95% CI, 0.807-0.877), patients with pancreatic AC (HR, 0.83; 95% CI, 0.757-0.91), and patients treated with chemotherapy (HR, 0.416; 95% CI, 0.406-0.427). CONCLUSIONS: Risk factors for cardiovascular mortality in GI adenocarcinoma include advanced age, males, whites, separated and widowed, gastric or colorectal adenocarcinoma, advanced grade or advanced stage of the disease, no chemotherapy, and no surgery. Married and divorced, and patients with pancreatic adenocarcinoma have a lower risk.

Efficacy of Cognitive Behavioral Therapy in Heart Failure Patients: A Systematic Review and Meta-Analysis.

BACKGROUND: Heart failure (HF) is a global disorder affecting around 6.2 million Americans aged 20 years and above. Neurovegetative disorders are common among such patients, and depression is a major problem that affects 20% to 40% of them. Cognitive behavioral therapy (CBT) is a type of treatment that produces the most favorable results compared to other psychotherapies, especially among patients with depression and anxiety. We aim to summarize and synthesize evidence regarding the efficacy of CBT for patients with HF. METHODS: We conducted this study by searching PubMed, Scopus, and Web of Science for relevant studies about CBT use in patients with HF. The outcomes were pooled as mean difference (MD) or standard MD with a 95% CI. The analysis was performed using the RevMan software. RESULTS: Combined data from 9 randomized controlled trials (1070 patients) revealed that CBT can alleviate both depression symptoms in HF patients when measured using different scales after 3 months of follow-up (standard MD, -0.18 [95% CI, -0.33 to -0.02]; P = 0.03) and the quality of life after 3 and 6 months of follow-up (MD, 4.92 [95% CI, 1.14-8.71]; P = 0.01 and MD, 7.72 [95% CI, 0.77-14.68]; P = 0.03, respectively). CONCLUSION: CBT is an effective type of psychotherapy for dealing with depression, mediocre quality of life, and defective physical functioning; therefore, it should be considered in HF patients' care.

Comparison of Percutaneous Coronary Intervention-Related Adverse Cardiac Outcomes in Patients With in-stent vs de novo Chronic Total Occlusion: A Systematic Review and Meta-Analysis.

Contemporary literature reveals a range of cardiac complications in patients who receive the percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). This study compared the adverse cardiac outcomes and procedural/technical success rates between the patients groups of in-stent (IS) CTO PCI and de novo CTO PCI. This systematic review and meta-analysis compared odds for primary (all-cause mortality, MACE, cardiac death post PCI, stroke) and secondary (bleeding requiring blood transfusion, ischemia-driven target-vessel revascularization, PCI procedural success, PCI technical success, and target-vessel MI) endpoints between 2734 patients who received PCI for IS CTO and 17,808 for de novo CTO. Odds ratios for outcome variables were calculated within 95% confidence intervals (CIs) via the Mantel-Haenszel method. The pooled analysis was undertaken for observational (retrospective/prospective) single- and multicentered studies published between January 2005 and December 2021. We found 57% higher, 166% higher, 129% higher, and 57% lower odds for MACE (OR: 1.57, 95% CI 1.31, 1.89, P < 0.001), ischemia-driven target-vessel revascularization (OR: 2.66, 95% CI 2.01, 3.53, P < 0.001), target-vessel myocardial infarction (MI) (OR: 2.29, 95% CI 1.70, 3.10, P < 0.001), and bleeding requiring blood transfusion (OR: 0.43, 95% CI 0.19, 1.00, P = 0.05), respectively, in patients with IS CTO PCI as compared to that of the de novo CTO PCI. No statistically significant differences between the study groups were recorded for the other primary/secondary outcome variables. The findings from this study indicated a high predisposition for MACE, ischemia-driven target-vessel revascularization, target vessel MI, and a lower incidence of bleeding episodes among IS CTO PCI patients as compared to those with de novo CTO PCI. The prognostic outcomes in CTO PCI cases require further investigation with randomized controlled trials.

Sickle Cell Disease and COVID-19 Infection: Importance of COVID-19 Testing and Approach to Management.

Sickle cell disease is an autosomal recessive disorder resulting in the substitution of CTG by CAG in the sixth codon of the beta-globin gene. As a result of this, the hydrophilic glutamic acid residue is replaced by hydrophobic valine residue, leading to the formation of hemoglobin tetramer HBS. This alteration in the beta-globin chain makes the red blood cells prone to sickling, especially in the presence of risk factors such as stress, hypoxia, and infection. These sickled red blood cells have the tendency to adhere to the endothelium and lead to vessel occlusion and distal tissue ischemia. The recent coronavirus disease 2019 (COVID-19) outbreak has impacted millions across the globe, putting individuals with co-morbidities at particularly high risk, and patients with sickle cell disease are no exception. We present the case of a 47-year-old African American male presenting to the emergency department with subjective fevers and a two-day history of pain in the arms, legs, and chest. A diagnosed case of sickle cell disease, the patient was on hydromorphone for pain management but ran out of his medications a few weeks before presentation. On examination, the patient was saturating well with mild tenderness upon palpation of the arms, legs, and chest. On complete blood count, the patient had a hemoglobin of 11.3 g/dL and a white cell count of 13.1 x10(3)/mcL. The patient had a normal mean corpuscular volume with reticulocytosis, hypochromia, ovalocytosis, poikilocytosis, polychromasia, and target cells. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) was positive. The chest X-ray did not reveal any significant findings. He was admitted to the medicine floor for the management of sickle cell crisis and was placed under airborne and droplet precautions. The patient was started on hydromorphone for pain management and intravenous fluid hydration. On the second day of admission, the patient reported increasing shortness of breath. He was saturating 90% on room air and 94% on 2 liters of supplemental oxygen. The white blood cell count increased to 18.42 x10(3)/mcL and the chest X-ray revealed reticular densities with patchy alveolar opacities in the left lung. Given the decline in respiratory status, the patient was started on remdesivir. Over the course of his hospital stay, the patient's pain and respiratory status improved, with the patient saturating 97% on room air. He was discharged home with instructions to follow isolation precautions for at least two weeks, folic acid, and adequate pain management. An appointment was also scheduled for the patient to follow with a sickle cell nurse practitioner upon discharge.

The Impact of COVID-19 Infection on a Neurologically Compromised Male With Fahr's Disease Presenting With Acute Delirium and Aspiration Pneumonia: A Case Report.

Fahr's disease or idiopathic basal ganglia calcification is a rare, sporadic, genetically dominant, and inherited neurological condition that manifests with dysphagia and Parkinson's disease. The computed tomography (CT) scan is the method of choice to diagnose basal ganglia calcifications seen in Fahr's disease. This case report elaborates on the emergency management of a 58-year-old male patient with acute respiratory distress, acute delirium, schizophrenia, Fahr's syndrome, and history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease 2019 or COVID-19) infection. The patient's chest X-ray, laboratory workup, and vital signs were suggestive of aspiration pneumonia-induced sepsis and acute hypoxemic respiratory failure. Post-admission antibiotic management reduced sepsis complications without improving the altered mental status. A comprehensive clinical assessment suggested the attribution of Fahr's disease to the patient's aspiration pneumonia and other clinical complications. In addition, COVID-19 infection, sepsis-induced inflammatory processes, and pre-existing neurological compromise possibly deteriorated the patient's neurological outcomes, overall prognosis, and recovery.

Lactulose-Induced Ischemic Colitis: A Rare Presentation and an Overview of Possible Etiologies of the Disease.

Ischemic colitis is one of the most common ischemic pathologies of the gastrointestinal system and can be divided into non-gangrenous and gangrenous forms. The pathophysiology involves restricted blood supply to the colonic mucosa. Several risk factors have been implicated in the development of ischemic colitis. Lactulose, one of the mainstay therapies for the treatment of hepatic encephalopathy in patients with cirrhosis, has been rarely reported as a cause of ischemic colitis. To the best of our knowledge, there has been only one case report associating lactulose use with the development of ischemic colitis. The exact pathophysiology is unknown but might be associated with the fermentation of lactulose by intestinal bacteria, causing gaseous distention and increasing the intraluminal pressure. We present the case of a 77-year-old African American male, a known case of non-alcoholic liver cirrhosis with portal hypertension and esophageal varices, brought in by his family to the emergency department for altered mental status, non-bilious vomiting, abdominal distension, and pain for one day. On physical examination, the patient had upper extremity asterixis and was alert but disoriented to place and person. Diagnostic paracentesis was performed, which revealed leukocytosis, predominantly neutrophils. The patient was admitted for spontaneous bacterial peritonitis and hepatic encephalopathy with decompensated liver cirrhosis. The patient was started lactulose with a goal of three to four bowel movements per day. Despite adequate treatment, the patient continued to develop worsening mental function and abdominal distension. This was later followed by a bloody bowel movement. Laboratory assessment showed an elevated white blood cell count, worsening kidney function, and high anion gap metabolic acidosis. CT scan revealed dilated loops of bowel with air and fluid along with submucosal wall edema, findings suggestive of ischemic colitis. Given the poor prognosis and the patient's condition, colonoscopy was deferred. Lactulose was discontinued, as it was thought to be a contributing cause of the patient's ischemic colitis. His condition continued to deteriorate, and he passed away on Day 18 of admission.

Acute Pancreatitis and Prognosticating Its Severity in Young Adults: A Case Report.

Acute pancreatitis develops into mild acute, moderately severe, and severe forms in multiple clinical scenarios. The severity assessment of pancreatitis relies on various scoring systems, including CT Severity Index (CTSI), Multiple Organ Dysfunction Syndrome (MODS), Acute Physiology and Chronic Health Evaluation II (APACHE-II), Bedside Index for Severity in Acute Pancreatitis (BISAP), Systemic Inflammatory Response Syndrome (SIRS), Multiple Organ System Score (MOSS), Glasgow score, and Ranson's Criteria (RC). This case report corresponds to a 20-year-old male with acute pancreatitis of unknown etiology. The RC scoring method produced two points, which could not prognosticate the possible severity of acute pancreatitis in the young patient. The hospital course included intubation with mechanical ventilation and ICU management.

Coronary Artery Calcium Score directed risk stratification of patients with Type-2 diabetes mellitus.

BACKGROUND AND AIMS: This study aimed to review the available data on the role of coronary artery calcium (CAC) scoring as the preferred adjunct modality to improve risk prediction and reduce the incidence of major adverse cardiac events and mortality in T2DM patients. METHODS: We reviewed the findings of 21 studies. RESULTS: This study revealed that the CAC scoring system could enhance cardiovascular disease (CVD) risk stratification and positively affect the medical management of patients with T2DM. CONCLUSION: A CAC scoring approach is necessary to reduce the incidence and prevalence of preventable CVD events in patients with type 2 diabetes.

New-Onset Atrial Fibrillation in COVID-19 Infection: A Case Report and Review of Literature.

Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, many cases of arrhythmias have been reported in patients with COVID-19 infection. We present the case of a 66-year-old female with no known cardiovascular history who presented with worsening shortness of breath and productive cough and tested positive for COVID-19 infection in the ED. The patient had a recent hospitalization for COVID-19 infection during which she was treated with dexamethasone and remdesivir therapy and her course remained uncomplicated at that time. Following this, she developed worsening shortness of breath at home for which she presented to the ED. During this hospitalization, she was treated with dexamethasone, remdesivir, and supplemental oxygen. On day six of hospitalization, the patient became tachycardic and had palpitations. Cardiac monitor and EKG showed evidence of new-onset atrial fibrillation (NOAF). Initially patient received metoprolol and diltiazem, both of which failed to achieve adequate rate control. Following this, the patient was started on carvedilol 30 mg every six hours, which attained good rate control. Her CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 (doubled), diabetes, stroke (doubled), vascular disease, age 65 to 74, and sex category) score was 4 for which she was started on apixaban 5mg twice daily. The patient was discharged on the same medications. Despite increasing reported incidences of NOAF in COVID-19 infection, only little is known about the optimal management strategies and possible etiopathology. The aim of our review is to highlight the possible mechanisms triggering atrial fibrillation in COVID-19 infection and go over the management strategies while reviewing the available literature.
