Article Synopsis
  • The study aimed to determine if additional doses of the COVID-19 vaccine correlate with fewer COVID-19-like symptoms six weeks after infection among health care workers.
  • A total of 2478 participants were enrolled, with 57% confirmed cases of COVID-19; symptoms like fatigue and sleep difficulties were common, especially in those infected.
  • Results indicated that those who received extra vaccine doses after their primary series experienced significantly lower odds of symptoms at six weeks post-infection compared to those who did not get boosted.

Axicabtagene ciloleucel (axi-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for relapsed/refractory (R/R) follicular lymphoma (FL). Approval was supported by the phase 2, multicenter, single-arm ZUMA-5 study of axi-cel for patients with R/R indolent non-Hodgkin lymphoma (iNHL; N = 104), including FL and marginal zone lymphoma (MZL). In the primary analysis (median follow-up, 17.

Background: Initiation of evidence-based medications for patients with heart failure with reduced ejection fraction (HFrEF) during hospitalization in contemporary practice is unknown.

Objectives: This study characterized opportunities for and achievement of heart failure (HF) medication initiation.

Methods: Using the GWTG-HF (Get With The Guidelines-Heart Failure) Registry 2017-2020, which collected data on contraindications and prescribing for 7 evidence-based HF-related medications, we assessed the number of medications for which each patient with HFrEF was eligible, use before admission, and prescribed at discharge.

Nonalcoholic fatty liver disease is the most common chronic liver disease in children in the United States and encompasses a range of disease from steatosis to cirrhosis. The mainstay of treatment is lifestyle modifications like increased physical activity and healthier eating habits. These are sometimes augmented with medications or surgery for weight loss.

Impact of the Share 35 Policy on Perioperative Management and Mortality in Liver Transplantation Recipients.

Ann Transplant

October 2021

Department of Surgery, Ronald Reagan University of California Los Angeles Medical Center, David Geffen School of Medicine, Los Angeles, CA, USA.

BACKGROUND The Share 35 policy was introduced in 2013 by the Organ Procurement and Transplantation Network (OPTN) to increase opportunities of sicker patients to access liver transplantation. However, it has the disadvantage of higher MELD score associated with adverse postoperative transplant outcomes. Early data after implementation of the Share 35 policy showed significantly poorer post-transplantation survival in some UNOS regions.

Traumatic brain injury (TBI) is responsible for the majority of trauma-related deaths and is a leading cause of disability. It is characterized by an inflammatory process involved in the progression of secondary brain injury. TBI is measured by the Glasgow Coma Scale (GCS) with scores ranging from 15-3, demonstrating mild to severe brain injury.

Catheter-based ablation techniques have a well-established role in atrial fibrillation (AF) management. The prevalence and impact of AF is increasing globally, thus mandating an emphasis on improving ablation techniques through innovation. One key area of ongoing evolution in this field is the use of laser energy to perform pulmonary vein isolation during AF catheter ablation.

Article Synopsis
  • - The study aimed to evaluate the effectiveness of avelumab, a PD-L1 inhibitor, as maintenance therapy for patients with unresectable gastric or gastroesophageal junction cancer after initial chemotherapy.
  • - In a phase III trial involving 805 patients, those on avelumab had a median overall survival (OS) of 10.4 months compared to 10.9 months for those continuing chemotherapy, indicating no significant survival advantage.
  • - Side effects were more common in the chemotherapy group (77.3% with grade ≥ 3 adverse events for chemotherapy vs. 61.3% for avelumab), suggesting that avelumab might have a better safety profile, particularly for patients with PD-L1-positive tumors

Venovenous Bypass During Liver Transplantation: A New Look at an Old Technique.

Transplant Proc

April 2020

Departments of Anesthesiology, Ronald Reagan University of California Los Angeles Medical Center, David Geffen School of Medicine, Los Angeles, California, United States. Electronic address:

Venovenous bypass (VVB) is a technique that was developed in the 1980s to mitigate untoward hemodynamic effects of complete cross-clamping of the inferior vena cava during liver transplantation (LT). Since the introduction of nonclassic surgical techniques, the interest in using VVB has decreased. Despite this, VVB is still commonly practiced today.

Chimeric Antigen Receptor T-Cell Therapy for Cancer and Heart: JACC Council Perspectives.

J Am Coll Cardiol

December 2019

Department of Medicine, Weill Cornell Medical College, New York, New York; Cardiology Service, Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, New York. Electronic address:

Chimeric antigen receptor (CAR) T-cell therapy has significantly advanced the treatment of patients with relapsed and refractory hematologic malignancies and is increasingly investigated as a therapeutic option of other malignancies. The main adverse effect of CAR T-cell therapy is potentially life-threatening cytokine release syndrome (CRS). Clinical cardiovascular (CV) manifestations of CRS include tachycardia, hypotension, troponin elevation, reduced left ventricular ejection fraction, pulmonary edema, and cardiogenic shock.

Objectives: This study sought to describe the short-term health status benefits of angiotensin-neprilysin inhibitor (ARNI) therapy in patients with heart failure and reduced ejection fraction (HFrEF).

Background: Although therapy with sacubitril/valsartan, a neprilysin inhibitor, improved patients' health status (compared with enalapril) at 8 months in the PARADIGM-HF (Prospective Comparison of ARNI with ACE inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) study, the early impact of ARNI on patients' symptoms, functions, and quality of life is unknown.

Methods: Health status was assessed by using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ) in 3,918 outpatients with HFrEF and left ventricular ejection fraction ≤40% across 140 U.

Background Intravenous recombinant tissue-type plasminogen activator (rtPA) remains the only medical therapy to improve outcomes for acute ischemic stroke (AIS), but the safety of rtPA in AIS patients with a history of recent myocardial infarction (MI) remains controversial. Methods and Results We sought to determine whether the presence of recent MI would alter the risk of mortality and rtPA-related complications. Multivariate logistic regression models were used to compare in-hospital outcomes between rtPA-treated AIS patients with recent MI within 3 months and those with no history of MI from the Get With The Guidelines-Stroke hospitals between February 2009 and December 2015.

Importance: A roadblock for research on adductor spasmodic dysphonia (ADSD), abductor SD (ABSD), voice tremor (VT), and muscular tension dysphonia (MTD) is the lack of criteria for selecting patients with these disorders.

Objective: To determine the agreement among experts not using standard guidelines to classify patients with ABSD, ADSD, VT, and MTD, and develop expert consensus attributes for classifying patients for research.

Design, Setting And Participants: From 2011 to 2016, a multicenter observational study examined agreement among blinded experts when classifying patients with ADSD, ABSD, VT or MTD (first study).

Treatment outcomes of patients with primary squamous cell carcinoma of the retromolar trigone.

Laryngoscope

December 2018

Department of Head and Neck Surgery, David Geffen School of Medicine , University of California Los Angeles, Los Angeles, California.

Objectives/hypothesis: Squamous cell carcinoma of the retromolar trigone (RMT SCC) is a relatively uncommon primary site for oral cavity malignancy. However, given its proximity to the mandible and buccal mucosa, RMT SCC typically exhibits early invasion and generally presents at an advanced stage. Large-sample studies are needed to assess the epidemiology and clinical outcomes of this tumor.
