RESUMO
Allogeneic hematopoietic stem cell transplant (allo-HSCT) is increasingly being used in the United States (US) and across the world as a curative therapeutic option for patients with certain high-risk hematologic malignancies and non-malignant diseases. However, racial and ethnic disparities in utilization of the procedure and in outcome following transplant remain major problems. Racial and ethnic minority patients are consistently under-represented in the proportion of patients who undergo allo-HSCT in the US. The transplant outcomes in these patients are also inferior. The interrelated driving forces responsible for the differences in the utilization and transplant outcome of the medical intervention are socioeconomic status, complexity of the procedure, geographical barriers, and the results of differences in the genetics and comorbidities across different races. Bridging the disparity gaps is important not only to provide equity and inclusion in the utilization of this potentially life-saving procedure but also in ensuring that minority groups are well represented for research studies about allo-HSCT. This is required to determine interventions that may be more efficacious in particular racial and ethnic groups. Various strategies at the Federal, State, and Program levels have been designed to bridge the disparity gaps with varying successes. In this review paper, we will examine the disparities and discuss the strategies currently available to address the utilization and outcome gaps between patients of different races in the US.

Since its release in 2022, Chat Generative Pre-Trained Transformer (ChatGPT) became the most rapidly expanding consumer software application in history,1 and its role in medicine is underscored by its potential to enhance patient education and physician-patient communication. Previous studies in gastroenterology and hepatology have focused primarily on the earlier Generative Pre-Trained Transformer 3 (GPT-3) model, with none investigating ChatGPT's ability to generate supportive references for its responses, or its applicability as a physician educational tool.2-6 Our study evaluated the accuracy of the more recent ChatGPT, powered by GPT-4, in addressing frequently asked questions by patients on irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colonoscopy and colorectal cancer (CRC) screening, questions on CRC screening from a physician perspective, and reference generation and suitability.
RESUMO
The intestinal barrier is a complex structure that not only regulates the influx of luminal contents into the systemic circulation but is also involved in immune, microbial, and metabolic homeostasis. Evidence implicating disruption in intestinal barrier functions in the development of many systemic diseases, ranging from non-alcoholic steatohepatitis to autism, or systemic complications of intestinal disorders has increased rapidly in recent years, raising the possibility of the intestinal barrier as a potential target for therapeutic intervention to alter the course and mitigate the complications associated with these diseases. In addition to the disease process being associated with a breach in the intestinal barrier functions, patients with hematologic and oncologic diseases are particularly at high risks for the development of increased intestinal permeability, due to the frequent use of broad-spectrum antibiotics and chemoradiation. They also face a distinct challenge of being intermittently severely neutropenic due to treatment of the underlying conditions. In this review, we will discuss how hematologic and oncologic diseases are associated with disruption in the intestinal barrier and highlight the complications associated with an increase in the intestinal permeability. We will explore methods to modulate the complication. To provide a background for our discussion, we will first examine the structure and appraise the methods of evaluation of the intestinal barrier.

Colorectal cancer has been around for a long time, but is still a challenge nonetheless. However, the heterogeneity of the disease opens new potential therapeutic doors. BRAF-mutated advanced colorectal cancer is a demanding entity that does not respond to standard chemotherapy regimens (FOLFOX, capecitabine) and the presence of the mutation significantly weakens the prognosis, but the rise of immunotherapy could reverse the trend. Indeed, pembrolizumab and nivolumab have boasted promising outcomes and increased survival rates among this subset of patients. This article is a collection of these results which could potentially bring immunotherapy to the front line.

Echocardiography, in all its forms (transthoracic echocardiography [TTE], transesophageal echocardiography [TEE], and intracardiac echocardiography [ICE]), is pivotal for the evaluation, guidance, and follow-up of transcatheter tricuspid edge-to-edge repair (TV-TEER) therapies. Although two-dimensional (2D) echocardiography remains essential, three-dimensional (3D) echo with multiplanar reconstruction (MPR) has revolutionized the field of structural imaging. In addition, the advent of 3D ICE has added an important modality to the imaging toolbox, particularly helpful when intraprocedural TEE images are challenging. In this review, we provide a detailed, step-by-step approach for advanced echocardiographic guidance of TV-TEER using 3D MPR.

INTRODUCTION: The importance of preventive medicine and primary care in the sphere of public health is expanding, yet a gap exists in the utilization of recommended medical services. As patients increasingly turn to online resources for supplementary advice, the role of artificial intelligence (AI) in providing accurate and reliable information has emerged. The present study aimed to assess ChatGPT-4's and Google Bard's capacity to deliver accurate recommendations in preventive medicine and primary care. METHODS: Fifty-six questions were formulated and presented to ChatGPT-4 in June 2023 and Google Bard in October 2023, and the responses were independently reviewed by two physicians, with each answer being classified as "accurate," "inaccurate," or "accurate with missing information." Disagreements were resolved by a third physician. RESULTS: Initial inter-reviewer agreement on grading was substantial (Cohen's Kappa was 0.76, 95%CI [0.61-0.90] for ChatGPT-4 and 0.89, 95%CI [0.79-0.99] for Bard). After reaching a consensus, 28.6% of ChatGPT-4-generated answers were deemed accurate, 28.6% inaccurate, and 42.8% accurate with missing information. In comparison, 53.6% of Bard-generated answers were deemed accurate, 17.8% inaccurate, and 28.6% accurate with missing information. Responses to CDC and immunization-related questions showed notable inaccuracies (80%) in both models. CONCLUSIONS: ChatGPT-4 and Bard demonstrated potential in offering accurate information in preventive care. It also brought to light the critical need for regular updates, particularly in the rapidly evolving areas of medicine. A significant proportion of the AI models' responses were deemed "accurate with missing information," emphasizing the importance of viewing AI tools as complementary resources when seeking medical information.

BACKGROUND: There are limited data on the sex differences in the hemodynamic progression and outcomes of early-stage aortic stenosis (AS). OBJECTIVES: The authors sought to determine sex differences in hemodynamic progression and outcomes of mild to moderate native AS. METHODS: This was a retrospective observational cohort study including patients with mild to moderate native tricuspid AS from the Cleveland Clinic echocardiographic database between 2008 and 2016 and followed until 2018. All-cause mortality, aortic valve replacement (AVR), and disease progression assessed by annualized changes in echocardiographic parameters were analyzed based on sex. RESULTS: The authors included 2,549 patients (mean age, 74 ± 7 years and 42.5% women) followed over a median duration of 5.7 years. There was no difference in all-cause mortality between sexes irrespective of age, baseline disease severity, progression to severe AS, and receipt of AVR. Relative to men, women had similar all-cause mortality but lower risk of AVR (adjusted HR: 0.81 [95% CI: 0.67-0.91]; P = 0.009) at 10 years. On 1:1 propensity-matched analysis, men had a significantly faster disease progression represented by greater increases in the median of annualized change in mean gradient (2.10 vs 1.15 mm Hg/y, respectively, P < 0.001), maximum transvalvular velocity (0.42 vs 0.28 m/s/y), left ventricular end-diastolic diameters (0.15 vs 0.048 mm/m2.7/y) (P = 0.014). Women have significantly higher left ventricular ejection fraction, filling pressures, and left ventricular septum thickness over time on follow-up echocardiograms compared with men. CONCLUSIONS: Women with mild to moderate AS had slower hemodynamic progression of AS, were more likely to have preserved left ventricular ejection fraction and concentric left ventricular hypertrophy in addition to lower incidence of AVR compared with men despite similar mortality. These findings provide further evidence that there are distinct sex-specific longitudinal echocardiographic and clinical profiles in patients with AS.

BACKGROUND: Data regarding permanent pacemaker (PPM) implantation following tricuspid valve surgery (TVS) are limited. We sought to evaluate its incidence, risk factors, and outcomes. METHODS AND RESULTS: Medicare beneficiaries who underwent TVS from 2013 to 2020 were identified. Patients who underwent TVS for endocarditis were excluded. The primary exposure of interest was new PPM after TVS. Outcomes included all-cause mortality and readmission with endocarditis or heart failure on follow-up. Among the 13 294 patients who underwent TVS, 2518 (18.9%) required PPM placement. Risk factors included female sex (relative risk [RR], 1.26 [95% CI, 1.17-1.36], P<0.0001), prior sternotomy (RR, 1.12 [95% CI, 1.02-1.23], P=0.02), preoperative second-degree heart block (RR, 2.20 [95% CI, 1.81-2.69], P<0.0001), right bundle-branch block (RR, 1.21 [95% CI, 1.03-1.41], P=0.019), bifascicular block (RR, 1.43 [95% CI, 1.06-1.93], P=0.02), and prior malignancy (RR, 1.23 [95% CI, 1.01-1.49], P=0.04). Tricuspid valve (TV) replacement was associated with a significantly higher risk of PPM implantation when compared with TV repair (RR, 3.20 [95% CI, 2.16-4.75], P<0.0001). After a median follow-up of 3.1 years, mortality was not different in patients who received PPM compared with patients who did not (hazard ratio [HR], 1.02 [95% CI, 0.93-1.12], P=0.7). PPM placement was not associated with a higher risk of endocarditis but was associated with a higher risk of heart failure readmission (HR, 1.28 [95% CI, 1.14-1.43], P<0.001). CONCLUSIONS: PPM implantation frequently occurs after TVS, notably in female patients and patients undergoing TV replacement. Although mortality is not increased, it is associated with higher rates of heart failure rehospitalization.

OBJECTIVE: Patients with moderate aortic stenosis (AS) exhibit high morbidity and mortality. Limited evidence exists on the role of aortic valve replacement (AVR) in this patient population. To investigate the benefit of AVR in moderate AS on survival and left ventricular function. METHODS: In a retrospective cohort study, patients with moderate AS between 2008 and 2016 were selected from the Cleveland Clinic echocardiography database and followed until 2018. Patients were classified as receiving AVR or managed medically (clinical surveillance). All-cause and cardiovascular mortality were assessed by survival analyses. Temporal haemodynamic and structural changes were assessed with longitudinal analyses using linear mixed effects models. RESULTS: We included 1421 patients (mean age, 75.3±5.4 years and 39.9% women) followed over a median duration of 6 years. Patients in the AVR group had lower risk of all-cause (adjusted HR (aHR)=0.51, 95% CI: 0.34 to 0.77; p=0.001) and cardiovascular mortality (aHR=0.50, 95% CI: 0.31 to 0.80; p=0.004) compared with those in the clinical surveillance group irrespective of sex, receipt of other open-heart surgeries and underlying malignancy. These findings were seen only in those with preserved left ventricular ejection fraction (LVEF) ≥50%. Further, patients in the AVR group had a significant trend towards an increase in LVEF and a decrease in right ventricular systolic pressure compared with those in the clinical surveillance group. CONCLUSIONS: In patients with moderate AS, AVR was associated with favourable clinical outcomes and left ventricular remodelling.

BACKGROUND: There are significant sex and age differences in left ventricular (LV) remodeling that may lead to disparity in outcomes when used to inform the timing of aortic regurgitation (AR) intervention. OBJECTIVES: The aim of this study was to examine whether left atrial (LA) parameters might represent better criteria than LV parameters to inform the timing of AR intervention. METHODS: Using data on patients with moderate to severe or severe AR with serial echocardiography (2010-2016), the longitudinal trends in left atrial volume index (LAVI) and left atrial reservoir strain (LAr) were evaluated by sex and age. The incremental utility of these parameters in predicting adverse events over LV parameters was also determined. RESULTS: In 525 patients (25.7% women) with 1,687 echocardiograms over a median follow-up period of 2.0 years (Q1-Q3: 1.0-3.6 years), there was significant increase in LAVI (1.0 mL/m2 per year [95% CI: 0.76-1.2 mL/m2 per year]) and decrease in LAr (-1.3% per year [95% CI: -1.6% to -0.92%]), without a significant interaction by sex or age category (P for interaction ≥ 0.17). In addition, both LAVI and LAr were significant predictors of adverse events independent of LV parameters. The optimal discriminatory thresholds were 37 mL/m2 for LAVI and 35% for LAr. These thresholds were similar across categories of sex and age. Within the relatively short-term follow-up, surgery was associated with survival benefit among patients with LAVI ≥37 mL/m2 (HR: 0.33 [95% CI: 0.15-0.72]; P = 0.006) but was not statistically significant among patients with LAVI <37 mL/m2 (HR: 0.46 [95% CI: 0.18-1.17]; P = 0.09). Similarly, surgery was associated with survival for the subgroup with LAr ≤35% but not among those with LAr >35%. CONCLUSIONS: Unlike LV remodeling, LA remodeling demonstrates a similar rate of progression between categories of sex and age among patients with AR. In addition, LA parameters provide incremental prognostic value over LV parameters.
RESUMO
The complications of endoscopic retrograde cholangiopancreatography (ERCP) are numerous and mainly intraluminal. We present a unique case of a patient who developed splenic hematoma after ERCP. A 41-year-old woman was hospitalized for evaluation of chronic abdominal pain, for which she underwent an ERCP. The next day, the patient developed hemorrhagic shock. She was found to have a large ruptured subcapsular splenic bleed. Splenic artery embolization was performed, and the patient was stabilized. In conclusion, a high index of suspicion should be kept when managing patients presenting with unstable vital signs and/or acute anemia after ERCP.
RESUMO
Despite the use of high-resolution molecular techniques for tissue typing, chronic graft-versus-host disease (cGVHD) remains a major complication following allogeneic hematopoietic stem cell transplant. cGVHD adversely affects the life-expectancy and quality of life. The latter is particularly important and functionally relevant in pediatric patients who have a longer life-expectancy than adults. Current laboratory evidence suggests that there is not any difference in the pathophysiology of cGVHD between adults and pediatric patients. However, there are some clinical features and complications of the disease that are different in pediatric patients. There are also challenges in the development of new therapeutics for this group of patients. In this review, we will discuss the epidemiology, pathophysiology, clinical features and consequences of the disease, and highlight the differences between pediatric and adult patients. We will examine the current treatment options for pediatric patients with moderate to severe cGVHD and discuss the challenges facing therapeutic development for cGVHD in the pediatric population.

Gallbladder cancer (GBC) is a relatively infrequent but highly lethal cancer with a poor prognosis. Management remains challenging and controversial, and most patients are diagnosed at an advanced stage. However, with the progressive advances in the use of immunotherapies, new treatment modalities are being implemented. In September 2022, the US FDA approved durvalumab (a PD-L1 inhibitor) in combination with chemotherapy for adult patients with locally advanced or metastatic GBC. This groundbreaking news is the first FDA approval for the use of immunotherapy in biliary tract cancers. This article reviews the newest advances and trials regarding immunotherapy for GBC.
Gallbladder cancer (GBC) is a malignant tumor that affects the cells of the gallbladder. Management of this condition is challenging and continuously evolving. Surgery, radiotherapy and chemotherapy are the current standards of care. However, recently, immunotherapy, a treatment that stimulates the host's immune system to target cancerous cells, has proven to be effective as a line of treatment. Promising results are continuously published. This article reviews the major advances in immunotherapy regarding the management of GBC.

â¢Cardiac computed tomography (CCT) can be used as a useful complementary tool in preprocedural planning of left atrial appendage closure.â¢CCT planning includes assessing exclusion criteria, device sizing, sheath selection, anticipating challenging anatomies, and transseptal puncture planning.â¢Procedural 3D intracardiac echocardiography (3D-ICE) is increasingly being used instead of transesophageal echocardiography. In this setting, preprocedural CCT is useful to compensate for 3D ICE's reduced resolution.
RESUMO
Infective endocarditis is a complex heterogeneous condition involving the infection of the endocardium and heart valves, leading to severe complications, including death. Surgery is often indicated in patients with infective endocarditis but is associated with elevated risk compared with other forms of cardiac surgery. Risk models play an important role in many cardiac surgeries as they can help inform clinicians and patients regarding procedural risk, decision-making to proceed or not, and influence perioperative management; however, they remain under-utilized in the infective endocarditis settings. Another crucial role of such risk models is to assess predicted versus found mortality, thereby allowing an assessment of institutional performance in infective endocarditis surgery. Traditionally, general cardiac surgery risk models such as European System for Cardiac Operative Risk Evaluation (EuroSCORE), EuroSCORE II, and Society of Thoracic Surgeon's score have been applied to endocarditis surgery. However, there has been the development of many endocarditis surgery-specific scores over the last decade. This review aims to discuss clinical characteristics and applications of all contemporary risk scores in the setting of surgical treatment of infective endocarditis.

A 64-year-old man presented with symptoms indicative of superior vena cava syndrome. Imaging work-up revealed an obstructing right atrial mass, which was subsequently excised and diagnosed as primary cardiac lymphoma. Post-surgery, the patient showed significant clinical improvement and was started on a chemotherapy regimen with complete remission at 1 year.
RESUMO
AIMS: Little data exist about the natural history and disease progression of secondary mitral regurgitation (SMR). We sought to study the temporal progression of left-sided volumes and functions in patients who progress to develop severe SMR. METHODS AND RESULTS: We screened patients with chronic severe SMR who had at least one previous transthoracic echocardiography showing non-severe MR. Unsupervised phenotypic clustering based on baseline and rate of change in left ventricular (LV) and left atrial (LA) volumes, ejection fraction (EF), and MR severity progression identified two different phenotypes. We then compared them in terms of clinical characteristics, mechanistic and anatomical features, management, and outcomes. A total of 257 patients were included. Cluster 1 started with lower EF and LA strain and higher LV and LA volumes compared with Cluster 2, with a slower progression into severe SMR. At the onset of severe MR, Cluster 2 still had higher EF, lower LV volumes, but similar LA volumes and strain, and less proportionate SMR, compared with Cluster 1. They also had higher tenting height and more compensatory leaflet growth. On follow-up, Cluster 1 had more ventricular-directed therapies, whereas Cluster 2 received more mitral valve interventions. While the heart failure burden was higher in Cluster 1, there was no difference in mortality rates. CONCLUSION: Based on disease progression, two distinct progression patterns of SMR exist, having different anatomical and mechanistic features with variation in management and outcomes.

Minimal residual disease (MRD) assessment using peripheral blood instead of bone marrow aspirate/biopsy specimen or the biopsy of the cancerous infiltrated by lymphoid malignancies is an emerging technique with enormous interest of research and technological innovation at the current time. In some lymphoid malignancies (particularly ALL), Studies have shown that MRD monitoring of the peripheral blood may be an adequate alternative to frequent BM aspirations. However, additional studies investigating the biology of liquid biopsies in ALL and its potential as an MRD marker in larger patient cohorts in treatment protocols are warranted. Despite the promising data, there are still limitations in liquid biopsies in lymphoid malignancies, such as standardization of the sample collection and processing, determination of timing and duration for liquid biopsy analysis, and definition of the biological characteristics and specificity of the techniques evaluated such as flow cytometry, molecular techniques, and next generation sequencies. The use of liquid biopsy for detection of minimal residual disease in T-cell lymphoma is still experimental but it has made significant progress in multiple myeloma for example. Recent attempt to use artificial intelligence may help simplify the algorithm for testing and may help avoid inter-observer variation and operator dependency in these highly technically demanding testing process.
RESUMO
We herein report the unusual case of a 52-year-old female with systemic scleroderma who was admitted to the emergency department (ED) with renal dysfunction and hypertension. Following a decline in hemoglobin (Hb) and platelet (Plt) count, the diagnosis of scleroderma renal crisis (SRC) with associated microangiopathic hemolytic anemia was made. Renal replacement therapy using hemodialysis was required. Systemic scleroderma is a chronic autoimmune multisystem vasculopathy affecting several vessel beds, including distal extremities, kidneys, and lungs. Microangiopathic hemolytic anemia occurs in almost half of patients who develop scleroderma renal crisis. This association is thought to be related to the activation of the complement system via the classical pathway. Based on that, we administered a C5 blocker (eculizumab) to our patient and reported an unprecedented positive outcome.
