Htx-011 Reduced Pain Intensity And Opioid Consumption Versus Bupivacaine Hcl In Bunionectomy: Phase Iii Results From The Randomized Epoch 1 Study., Eugene R. Viscusi, Joseph S. Gimbel, Richard A. Pollack, Jia Hu, Gwo-Chin Lee

Department of Anesthesiology Faculty Papers

BACKGROUND AND OBJECTIVES: There is a need for local anesthetics that provide consistent analgesia through 72 hours after surgery. This study evaluates the use of HTX-011 (bupivacaine and meloxicam in Biochronomerpolymer technology), an extended-release, dual-acting local anesthetic, in reducing both postoperative pain over 72 hours and postoperative opioid use when compared with bupivacaine hydrochloride (HCl) and saline placebo. Inclusion of low-dose meloxicam in HTX-011 is designed to reduce local inflammation caused by surgery, potentiating the analgesic effect of bupivacaine. Previously, significant synergy has been observed with bupivacaine and meloxicam with both given locally together.

Gangliosides: Treatment Avenues In Neurodegenerative Disease., Pierre J. Magistretti, Fred H. Geisler, Jay S. Schneider, P. Andy Li, Hubert Fiumelli, Simonetta Sipione

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Gangliosides are cell membrane components, most abundantly in the central nervous system (CNS) where they exert among others neuro-protective and -restorative functions. Clinical development of ganglioside replacement therapy for several neurodegenerative diseases was impeded by the BSE crisis in Europe during the 1990s. Nowadays, gangliosides are produced bovine-free and new pre-clinical and clinical data justify a reevaluation of their therapeutic potential in neurodegenerative diseases. Clinical experience is greatest with monosialo-tetrahexosyl-ganglioside (GM1) in the treatment of stroke. Fourteen randomized controlled trials (RCTs) in overall >2,000 patients revealed no difference in survival, but consistently superior neurological outcomes vs. placebo. GM1 was shown …

Astragaloside Iv Protects Neurons From Microglia-Mediated Cell Damage Through Promoting Microglia Polarization., Jingwen Yu, Minfang Guo, Yanhua Li, Huiyu Zhang, Zhi Chai, Qing Wang, Yuqing Yan, Jiezhong Yu, Chunyun Liu, Guang-Xian Zhang, Ma Cungen

Department of Neurology Faculty Papers

Astragaloside IV (AST-IV) is a major active ingredient of astragalus, with a neuroprotective effect. The current study is aimed to investigate the impact of AST-IV on the M1/M2 microglial activation in response to lipopolysaccharide (LPS) stimulation, how AST-IV attenuated microglia-mediated neuronal damage, and the molecular mechanisms underlying AST-IV's protection of neurons against microglia-mediated neuronal damage. Our results showed that AST-IV partially protected microglia from death evoked by LPS and downregulated the release of pro-inflammatory (M1) mediators including interleukin (IL)-1β, IL-6, tumour necrosis factor α (TNF-α) and nitric oxide, as well as the expression of Toll-like receptors 4 (TLR4), MyD88, and …

Galcanezumab In Episodic Migraine: Subgroup Analyses Of Efficacy By High Versus Low Frequency Of Migraine Headaches In Phase 3 Studies (Evolve-1 & Evolve-2)., Stephen D. Silberstein, Virginia L. Stauffer, Katie A. Day, Sarah Lipsius, Maria-Carmen Wilson

Department of Neurology Faculty Papers

BACKGROUND: Patients with high-frequency episodic migraine (HFEM) have a greater disease burden than those with low-frequency episodic migraine (LFEM). Acute treatment overuse increases the risk of migraine chronification in patients with HFEM. Galcanezumab, a humanized monoclonal antibody binding calcitonin gene-related peptide (CGRP), is effective for migraine prevention with a favorable safety profile. Here, we investigate whether there are differences in galcanezumab efficacy in patients with LFEM or with HFEM.

METHODS: Data were pooled from two double-blind, placebo-controlled phase 3 trials; EVOLVE-1 and EVOLVE-2. Patients were 18-65 years old, experienced 4-14 monthly migraine headache days (MHDs) for ≥1 year prior, with …

Department of Radiology Faculty Papers

Background: Although papillary thyroid microcarcinoma (PTMC) has a high incidence and excellent clinical outcome, debate continues as to the therapeutic approach that would be most appropriate after confirming the diagnosis.

Methods: We retrospectively analyzed the medical records of 311 patients with T1aN0M0 PTMC between January 2013 and September 2018. In all, 168 underwent microwave ablation (MWA), and 143 underwent surgery. MWA was performed using extensive ablation with hydrodissection. The surgery comprised thyroid lobectomy (TL) with unilateral central lymph node dissection (CND). We examined clinical outcomes during mean follow-up periods of 824 ± 452 days for the TL group and 753 …

A Prospective, Multi-Center, Randomized Comparison Of Iron Isomaltoside 1000 Versus Iron Sucrose In Patients With Iron Deficiency Anemia; The Ferwon-Ida Trial., Michael Auerbach, David Henry, Richard J. Derman, Maureen M. Achebe, Lars L. Thomsen, John Glaspy

Global Health Articles

Iron deficiency anemia (IDA) is prevalent, and intravenous iron, especially if given in a single dose, may result in better adherence compared with oral iron. The present trial (FERWON-IDA) is part of the FERWON program with iron isomaltoside 1000/ferric derisomaltose (IIM), evaluating safety and efficacy of high dose IIM in IDA patients of mixed etiologies. This was a randomized, open-label, comparative, multi-center trial conducted in the USA. The IDA patients were randomized 2:1 to a single dose of 1000 mg IIM, or iron sucrose (IS) administered as 200 mg intravenous injections, up to five times. The co-primary endpoints were adjudicated …

M6a Mrna Demethylase Fto Regulates Melanoma Tumorigenicity And Response To Anti-Pd-1 Blockade, Seungwon Yang, Jiangbo Wei, Yan-Hong Cui, Gayoung Park, Palak Shah, Yu Deng, Andrew E. Aplin, Zhike Lu, Seungmin Hwang, Chuan He, Yu-Ying He

Department of Cancer Biology Faculty Papers

Melanoma is one of the most deadly and therapy-resistant cancers. Here we show that N⁶-methyladenosine (m⁶A) mRNA demethylation by fat mass and obesity-associated protein (FTO) increases melanoma growth and decreases response to anti-PD-1 blockade immunotherapy. FTO level is increased in human melanoma and enhances melanoma tumorigenesis in mice. FTO is induced by metabolic starvation stress through the autophagy and NF-κB pathway. Knockdown of FTO increases m⁶A methylation in the critical protumorigenic melanoma cell-intrinsic genes including PD-1 (PDCD1), CXCR4, and SOX10, leading to increased RNA decay through the m⁶A reader YTHDF2. Knockdown of …

HLA-haploidentical hematopoietic cell transplantation (Haplo-HCT) using posttransplantation cyclophosphamide (PT-Cy) has improved donor availability. However, a matched sibling donor (MSD) is still considered the optimal donor. Using the Center for International Blood and Marrow Transplant Research database, we compared outcomes after Haplo-HCT vs MSD in patients with acute myeloid leukemia (AML) in first complete remission (CR1). Data from 1205 adult CR1 AML patients (2008-2015) were analyzed. A total of 336 patients underwent PT-Cy–based Haplo-HCT and 869 underwent MSD using calcineurin inhibitor–based graft-versus-host disease (GVHD) prophylaxis. The Haplo-HCT group included more reduced-intensity conditioning (65% vs 30%) and bone marrow grafts (62% vs …

Gpvi Inhibitor As Antitumor Gateway Drug., Lawrence E. Goldfinger

Department of Medicine Faculty Papers

In this issue ofBlood, Volz et al establish a potential antitumor strategy byexploiting the selective requirement for platelets to maintain vascular in-tegrity within the tumor microenvironment.1Their work demonstrates, forthefirst time, that functional inhibition of platelet-specific surface receptorglycoprotein (GP) VI, using F(ab9)2fragments to avoid platelet clearance,increases intratumoral hemorrhage and concomitant tumor cell apoptosis, aswell as enhanced accumulation of chemotherapeutic drugs. These effectswork additively to inhibit tumor growth, achieving results similar to thoseachieved by platelet depletion.

Stat3 Genotypic Variant Rs744166 And Increased Tyrosine Phosphorylation Of Stat3 In Il-23 Responsive Innate Lymphoid Cells During Pathogenesis Of Crohn's Disease, Ying Tang, Sanda A. Tan, Atif Iqbal, Jian Li, Sarah C. Glover

Department of Neurology Faculty Papers

Crohn's disease (CD) results from dysregulated immune responses to gut microbiota in genetically susceptible individuals, affecting multiple areas of the gastrointestinal tract. Innate lymphoid cells (ILCs) are tissue-resident innate effector lymphocytes which play crucial roles in mucosal immune defense, tissue repair, and maintenance of homeostasis. The accumulation of IFN-γ-producing ILC1s and increased level of proinflammatory cytokines produced by ILCs has been observed in the inflamed terminal ileum of CD patients. To date, the precise mechanisms of ILC plasticity and gene regulatory pathways in ILCs remain unclear. Signal transducer and activator of transcription 3 (STAT3) regulates gene expression in …

Heart Failure With Preserved Ejection Fraction: A Review Of The Acc/Aha Guidelines And Evidence-Based Management Strategy, Vikas Sunder, Md

The Medicine Forum

Introduction

Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which a patient has signs and symptoms of heart failure including dyspnea, fatigue, pulmonary rales, peripheral edema and an ejection fraction greater than 50%.1-4 Approximately half of patients with heart failure have a preserved ejection fraction.2-5 HFpEF is considered a distinct clinical entity from other causes of heart failure with a preserved ejection fraction such as valvular heart disease, pericardial disease, and infiltrative cardiomyopathy. HFpEF carries a poor prognosis, with an annual mortality of 29% in patients discharged after an acute decompensated heart failure admission.5 5-year survival …

A Gram-Negative False-Negative: Normal Procalcitonin Level In A Patient With Multiple Klebsiella Pneumoniae Intra-Abdominal Abscesses: A Case Report And Literature Review, Mario Caldararo, Md

The Medicine Forum

Introduction

Despite over 3,000 peer-reviewed articles on procalcitonin (PCT) since 2004, guidance on its usage is sparse.1 An analysis of more than 500 United States hospitals in the Premier Healthcare Database found large differences in utilization exist across regions (115 PCT encounters per 10,000 patients in the Northeast vs. 408 to 576 in other regions) and teaching vs. non-teaching hospitals (345 vs. 530 PCT encounters per 10,000 patients, respectively).2 The purpose of this work is to describe a case that exemplifies the caveats in PCT interpretation and to summarize the current knowledge of the clinical utilization of PCT.

Resident Experiences With Journaling, Tara Sunder, Md, Gretchen Diemer, Md, Vikas Sunder, Md

The Medicine Forum

Background

Each year, medical school graduates don their long white coat for the first time and begin their residency. While residency promises the excitement of learning and increased autonomy, it also brings long duty hours and stressful situations worsened by inexperience. Due to these stressors, burnout affects many residents each year. Studies have been done to see if wellness curricula help decrease resident burnout, and since journaling is a known way to relieve stress and enhance reflection, journaling has become a common intervention in these curricula.1,2 While there are studies evaluating the impact of journaling on mental health and stress …

Pneumatosis Intestinalis In A Patient With Systemic Lupus Erythematosus, Sean Dikdan, Md, Michael Lake, Md

The Medicine Forum

Introduction

Pneumatosis intestinalis (PI) refers to the radiographic finding of gas within the small or large bowel wall. It can be seen in association with gas in the portal venous system. The clinical significance of these findings is variable and depends on the patient's etiology and initial presentation. PI can be seen anywhere in the gastrointestinal tract distal to the stomach and is caused by a myriad of conditions.1 We present a case of a patient admitted to the intensive care unit with PI and portal vein gas.

Hemothorax And Hemorrhagic Ascites: A Rare Presentation Of Endometriosis, Harry Wang, Md

The Medicine Forum

Introduction

Endometriosis is a common diagnosis in reproductive age women characterized by the presence of endometrial tissue outside the uterine cavity.1 Although it is typically confined to the pelvis, rare manifestations involving the thorax, abdomen or pericardium have been documented.2-5 Even more rare is the concurrent presence of endometriosis- associated hemorrhagic pleural effusion and ascites, which can prove a diagnostic challenge. We describe a case of hemothorax and hemorrhagic ascites in a woman with shortness of breath and abdominal pain.

Subacute Onset Hand Clumsiness In A Renal Transplant Patient With A Recent Icu Stay, William Bradford, Md

The Medicine Forum

Introduction

Solid organ transplant recipients carry a high burden of disease and are susceptible to opportunistic infections not seen in other patient subgroups. Signs and symptoms that would not necessarily warrant timely attention in other patient groups may call for an aggressive workup in this subset of patients. Here, we present one case in which a seemingly trivial complaint denoted serious underlying pathology, and timely attention to this minor but unusual concern led to early intervention with appropriate treatment of an uncommon disorder.

Hyperviscosity In Non-Igm Lymphoplasmacytic Lymphoma, Mario Fonseca-Paricio, Md, Sushil Chmire, Md, Adam Binder, Md

The Medicine Forum

The following is a case of how a non-IgM paraproteinemia can present with symptoms of hyperviscosity and coagulopathy, an uncommon occurrence.1-3 As this case demonstrates, this diagnosis must be considered even in patients with relatively normal coagulation laboratory results. Such pathology requires urgent treatment with plasmapheresis.

Worsening Autoimmune Neutropenia After Stopping Ibrutinib In A Patient With Chronic Lymphocytic Leukemia: Case Report And Review Of Literature, Natalie Rosen, Ba, Thomas Klumpp, Md, Sameh Gaballa, Md, Msc

The Medicine Forum

Introduction

Autoimmune cytopenia (AIC) is relatively common in patients with chronic lymphocytic leukemia occurring in 5-10% of patients during the course of their disease.1 Autoimmune hemolytic anemia (AIHA) constitutes the highest prevalence (5-10%) of CLL-associated AIC followed by idiopathic thrombocytopenic purpura (ITP) (2-5%), pure red cell aplasia (PRCA) (<1%), and autoimmune neutropenia (AIN) (<1%).2,3 The prevalence of AIN, however, may in fact be higher than reported due to a lack of awareness of the condition and difficulty in its diagnosis.4 Despite its rarity, autoimmune neutropenia can be a significant clinical challenge in patients with CLL and can increase the risk of infectious complications. Thus, the prompt diagnosis and resolution of CLL-associated AIN is essential to the management of these patients.

Ibrutinib is a selective inhibitor of Bruton tyrosine kinase and induces a durable response in patients with CLL.5 The activity of ibrutinib in CLL-associated AIC is largely unknown as pivotal clinical trials excluded patients with AIC. We report a case of a patient with CLL who experienced worsening of AIN after …

Bilateral Choroidal Metastases As Initial Presentation Of Widespread Follicular Thyroid Cancer, Jennifer Hong, Md

The Medicine Forum

Introduction

Follicular thyroid cancer (FTC) is the second most common malignancy of the thyroid gland and comprise 10-15% of all thyroid tumors; the usual mode of spread is via hematogenous dissemination with the most common sites of metastases being the lungs and bones.4 A case is presented to demonstrate the unusual presentation of follicular thyroid cancer as bilateral choroidal metastases. Although exceptional, a diagnosis of choroidal metastases should be considered in any decline in visual acuity in patients with thyroid cancer.

Complicated Persistent Peritonitis, Lindsey Roth, Ba, Kumar Sarkar, Md

The Medicine Forum

Introduction

Spontaneous bacterial peritonitis (SBP) is a common complication of end-stage liver disease. SBP can present with many symptoms such as abdominal pain, fever and altered mental status.1 The diagnosis of SBP is made when ascitic fluid from a paracentesis has an absolute neutrophil count (ANC) more than 250/uL, there is a positive ascitic fluid culture, and no secondary source of infection can be idenitifed.2 However, nearly 60% of patients with SBP have negative fluid cultures.3 These patients can still potentially have SBP and should be treated as such since in-hospital mortality ranges from 20-40%.1,4 Conventional treatment for SBP includes …

Sealing The Diagnosis Of Celiac Disease In Pregnancy, Ritu Nahar, Md, Avani Aman, Md

The Medicine Forum

Introduction

Celiac disease (CD) is an immune mediated condition that results from a reaction to dietary gluten and primarily affects the small intestine. Genetically predisposed individuals develop a chronic inflammatory state of the small intestine which leads to malabsorption. The disease is mediated by HLA DQ2 or DQ8 haplotypes, which bind the gliadin peptides of gluten, present the peptides to CD4+ T lymphocytes and trigger cytokine and B lymphocyte responses.1

The prevalence of CD in the United States is approximately 1% and can reach up to 4-5% in at-risk groups.2 Serologic study of asymptomatic elderly patients in the United Kingdom …

Thyrotoxic Periodic Paralysis – A Case Report Of A Rare Cause Of Paralysis In A 39-Year-Old Asian Man, R. Benson Jones, Md, James Uricheck, Md

The Medicine Forum

Introduction

Uncontrolled hyper thyroidism has a myriad of presentations. Classically, symptoms include weight loss, tremor, palpitations, shortness of breath, diarrhea, anxiety, and heat intolerance. A rare manifestation of hyperthyroidism is thyrotoxic periodic paralysis (TPP). Periodic paralysis is a musculoskeletal channelopathy manifested by episodes of painless muscle weakness often precipitated by heavy exercise, fasting, or high carbohydrate meals. Although classically associated with painless weakness; cramping, myalgias, and stiffness can also occur prior to the episodes as prodromal symptoms. Neurologic examination during an attack typically demonstrates proximal more than distal muscle weakness, and the upper extremities are more commonly affected than the …

Hypoglycemia is most convincingly documented by Whipple’s triad: low plasma glucose, symptoms of hypoglycemia and relief of symptoms after treatment.1 Pseudohypoglycemia is a condition where there is an artifactually low glucose concentration and an absence of hypoglycemic symptoms. We present a case of pseudohypoglycemia where leukocytosis played a role in lowering venous glucose.

A Case Of Left Ventricular Myocardial Calcification In A Patient With Severe Sepsis, Carly Sedlock, Md, Randi Zukas, Md, Hillary Landon, Md

The Medicine Forum

Introduction

Sepsis is an important source of morbidity and mortality among patients admitted to the Intensive Care Unit (ICU) and can cause critical damage to all organ systems. Regarding cardiac complications, sepsis can acutely result in cardiomyopathy characterized by ventricular dilatation and a depressed ejection fraction.1 Myocardial calcification is a more rare, delayed cardiac complication of severe sepsis that has been reported in literature.1-6 Herein we report a case of a patient with Acute Myeloid Leukemia (AML) admitted to the TJUH ICU requiring prolonged vasopressor support for severe sepsis whose clinical course was complicated by left ventricular myocardial calcification.
