A Massive Overdose Of Dalfampridine, L. J. Fil, P. Sud, S. Sattler Jan 2015

A Massive Overdose Of Dalfampridine, L. J. Fil, P. Sud, S. Sattler

Journal Articles

Multiple sclerosis (MS) is an immune mediated inflammatory disease that attacks myelinated axons in the central nervous system. Dalfampridine (4-aminopyridine) was approved by the Food and Drug Administration in January 2010 for treatment of MS. Our patient was a 34-year-old male with a history of MS, who was brought to the emergency department after being found unresponsive. His current medications were valacyclovir, temazepam, dalfampridine (4-AP) and a tysabri intravenous (IV) infusion. Fifteen minutes after arrival the patient seized. The seizures were refractory to benzodiazepines, barbiturates and phenytoin. The 4-AP level was 530ng/mL (25ng/mL and 49ng/mL). The patient stopped seizing on …

Bleb Point: Mimicker Of Pneumothorax In Bullous Lung Disease, C. Gelabert, M. Nelson Jan 2015

Bleb Point: Mimicker Of Pneumothorax In Bullous Lung Disease, C. Gelabert, M. Nelson

Journal Articles

In patients presenting with severe dyspnea, several diagnostic challenges arise in distinguishing the diagnosis of pneumothorax versus several other pulmonary etiologies like bullous lung disease, pneumonia, interstitial lung disease, and acute respiratory distress syndrome. Distinguishing between large pulmonary bullae and pneumothorax is of the utmost importance, as the acute management is very different. While multiple imaging modalities are available, plain radiographs may be inadequate to make the diagnosis and other advanced imaging may be difficult to obtain. Ultrasound has a very high specificity for pneumothorax. We present a case where a large pulmonary bleb mimics the lung point and therefore …

Not Just Painless Bleeding: Meckel's Diverticulum As A Cause Of Small Bowel Obstruction In Children-Two Cases And A Review Of The Literature, K. Itriyeva, M. Harris, J. Rocker, R. Gochman Jan 2015

Not Just Painless Bleeding: Meckel's Diverticulum As A Cause Of Small Bowel Obstruction In Children-Two Cases And A Review Of The Literature, K. Itriyeva, M. Harris, J. Rocker, R. Gochman

Journal Articles

Physicians are educated with the classical teaching that symptomatic patients with Meckel's diverticulum (MD) most often present with painless rectal bleeding. However, a review of the literature reveals that young patients with MD will most commonly present with signs of intestinal obstruction, an etiology not frequency considered in patients presenting to the emergency department with obstruction. We present two cases of intestinal obstruction diagnosed in our emergency department, with Meckel's diverticulum being the etiology.

Hspb1 As A Novel Regulator Of Ferroptotic Cancer Cell Death, X. Sun, Z. Ou, M. Xie, R. Kang, Y. Fan, X. Niu, H. Wang, L. Cao, D. Tang Jan 2015

Hspb1 As A Novel Regulator Of Ferroptotic Cancer Cell Death, X. Sun, Z. Ou, M. Xie, R. Kang, Y. Fan, X. Niu, H. Wang, L. Cao, D. Tang

Journal Articles

Ferroptosis is an iron-dependent form of non-apoptotic cell death, but its molecular mechanism remains largely unknown. Here, we demonstrate that heat shock protein beta-1 (HSPB1) is a negative regulator of ferroptotic cancer cell death. Erastin, a specific ferroptosis-inducing compound, stimulates heat shock factor 1 (HSF1)-dependent HSPB1 expression in cancer cells. Knockdown of HSF1 and HSPB1 enhances erastin-induced ferroptosis, whereas heat shock pretreatment and overexpression of HSPB1 inhibits erastin-induced ferroptosis. Protein kinase C-mediated HSPB1 phosphorylation confers protection against ferroptosis by reducing iron-mediated production of lipid reactive oxygen species. Moreover, inhibition of the HSF1-HSPB1 pathway and HSPB1 phosphorylation increases the anticancer activity …

Evaluating Ct Perfusion Deficits In Global Cerebral Edema After Aneurysmal Subarachnoid Hemorrhage, H. Baradaran, V. Fodera, D. Mir, K. Kesavobhotla, J. Ivanidze, U. Ozbek, A. Gupta, J. Claassen, P. C. Sanelli Jan 2015

Evaluating Ct Perfusion Deficits In Global Cerebral Edema After Aneurysmal Subarachnoid Hemorrhage, H. Baradaran, V. Fodera, D. Mir, K. Kesavobhotla, J. Ivanidze, U. Ozbek, A. Gupta, J. Claassen, P. C. Sanelli

Journal Articles

BACKGROUND AND PURPOSE: Global cerebral edema is an independent predictor of mortality and poor outcomes after aneurysmal SAH. Global cerebral edema, a complex disease process, is thought to be associated with an altered cerebral autoregulatory response. We studied the association between cerebral hemodynamics and early global cerebral edema by using CTP. MATERIALS AND METHODS: We retrospectively studied consecutive patients with aneurysmal SAH with admission CTP performed at days 0-3. Two neuroradiologists classified global cerebral edema and hydrocephalus on NCCT performed concurrently with CTP. Global cerebral edema was defined as diffuse effacement of the sulci and/or basal cisterns or diffuse disruption …

Effect Of Reconstruction Algorithms On The Accuracy Of (99m)Tc Sestamibi Spect/Ct Parathyroid Imaging, K. J. Nichols, G. G. Tronco, C. J. Palestro Jan 2015

Effect Of Reconstruction Algorithms On The Accuracy Of (99m)Tc Sestamibi Spect/Ct Parathyroid Imaging, K. J. Nichols, G. G. Tronco, C. J. Palestro

Journal Articles

The superiority of SPECT/CT over SPECT for (99m)Tc-sestamibi parathyroid imaging often is assumed to be due to improved lesion localization provided by the anatomic component (computed tomography) of the examination. It also is possible that this superiority may be related to the algorithms used for SPECT data reconstruction. The objective of this investigation was to determine the effect of SPECT reconstruction algorithms on the accuracy of MIBI SPECT/CT parathyroid imaging. We retrospectively analyzed preoperative MIBI SPECT/CT parathyroid imaging studies performed on 106 patients. SPECT data were reconstructed by filtered back projection (FBP) and by iterative reconstruction with corrections for collimator …

The Role Of Factor Xa Inhibitors In Venous Thromboembolism Treatment, K. P. Cabral, J. E. Ansell Jan 2015

The Role Of Factor Xa Inhibitors In Venous Thromboembolism Treatment, K. P. Cabral, J. E. Ansell

Journal Articles

Three factor Xa inhibitors have been studied in the treatment of venous thromboembolism, both for acute therapy and as extended therapy to prevent recurrent events. Rivaroxaban, apixaban, and edoxaban have all proven to be effective in Phase III clinical trials for this indication when compared to current standard of therapy with similar or less bleeding. Nevertheless, the agents all offer different pharmacological profiles, which have an impact on patient selection and potential advantages in clinical practice.

Romidepsin is an epigenetic agent approved for the treatment of patients with cutaneous or peripheral T-cell lymphoma (CTCL and PTCL). Here we report data in all patients treated on the National Cancer Institute 1312 trial, demonstrating long-term disease control and the ability to retreat patients relapsing off-therapy. In all, 84 patients with CTCL and 47 with PTCL were enrolled. Responses occurred early, were clinically meaningful and of very long duration in some cases. Notably, patients with PTCL receiving romidepsin as third-line therapy or later had a comparable response rate (32%) of similar duration as the total population (38%). Eight patients …

Therapeutic Potential Of New B Cell-Targeted Agents In The Treatment Of Elderly And Unfit Patients With Chronic Lymphocytic Leukemia, K. R. Rai Jan 2015

Therapeutic Potential Of New B Cell-Targeted Agents In The Treatment Of Elderly And Unfit Patients With Chronic Lymphocytic Leukemia, K. R. Rai

Journal Articles

Chronic lymphocytic leukemia (CLL), the most common adult leukemia in the Western world, is primarily a disease of the elderly, with most patients >= 65 years of age and having at least one major comorbidity. Aggressive chemoimmunotherapy regimens recommended to achieve remission and improve survival in young, fit patients are often poorly tolerated in elderly and/or less physiologically fit ("unfit") patients, necessitating alternative treatment options. Although patient age, fitness, and comorbidities are key considerations in the selection of a treatment regimen, historically, clinical trials have been limited to young, fit patients by virtue of the ethical concerns associated with potential …

Journal Articles

BACKGROUND: Randomized controlled trials (RCTs) on pediatric venous thromboembolism (VTE) treatment have been challenged by unsubstantiated design assumptions and/or poor accrual. Pilot/feasibility (P/F) studies are critical to future RCT success. METHODS: The Kids-DOTT trial is a multicenter RCT investigating non-inferiority of a 6-week (shortened) versus 3-month (conventional) duration of anticoagulation in patients aged < 21 years with provoked venous thrombosis. Primary efficacy and safety endpoints are symptomatic recurrent VTE at 1 year and anticoagulant-related, clinically relevant bleeding. In the P/F phase, 100 participants were enrolled in an open, blinded-endpoint, parallel-cohort RCT design. RESULTS: No eligibility violations or randomization errors occurred. Of the enrolled patients, 69% were randomized, 3% missed the randomization window, and 28% were followed in prespecified observational cohorts for completely occlusive thrombosis or persistent antiphospholipid antibodies. Retention at 1 year was 82%. Interobserver agreement between local and blinded central determination of venous occlusion by imaging at 6 weeks after diagnosis was strong (k-statistic = 0.75; 95% confidence interval [CI] 0.48-1.0). The primary efficacy and safety event rates were 3.3% (95% CI 0.3-11.5%) and 1.4% (95% CI 0.03-7.4%). CONCLUSIONS: The P/F phase of the Kids-DOTT trial has demonstrated the validity of vascular imaging findings of occlusion as a randomization criterion, and defined randomization, retention and endpoint rates to inform the fully powered RCT.

Journal Articles

BACKGROUND: Therapeutic decisions in atrial fibrillation (AF) are often influenced by assessment of bleeding risk. However, existing bleeding risk scores have limitations. OBJECTIVES: We sought to develop and validate a novel bleeding risk score using routinely available clinical information to predict major bleeding in a large, community-based AF population. METHODS: We analysed data from Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF), a prospective registry that enrolled incident and prevalent AF patients at 176 US sites. Using Cox proportional hazards regression, we identified factors independently associated with major bleeding among patients taking oral anticoagulation (OAC) over a median …

Ferric Pyrophosphate Citrate (Triferic) Administration Via The Dialysate Maintains Hemoglobin And Iron Balance In Chronic Hemodialysis Patients, S. N. Fishbane, A. K. Singh, S. H. Cournoyer, K. K. Jindal, P. Fanti, C. D. Guss, V. H. Lin, R. D. Pratt, A. Gupta

Journal Articles

BACKGROUND: Administration of ferric pyrophosphate citrate (FPC, Triferic) via hemodialysate may allow replacement of ongoing uremic and hemodialysis-related iron losses. FPC donates iron directly to transferrin, bypassing the reticuloendothelial system and avoiding iron sequestration. METHODS: Two identical Phase 3, randomized, placebo-controlled trials (CRUISE 1 and 2) were conducted in 599 iron-replete chronic hemodialysis patients. Patients were dialyzed with dialysate containing 2 microM FPC-iron or standard dialysate (placebo) for up to 48 weeks. Oral or intravenous iron supplementation was prohibited, and doses of erythropoiesis-stimulating agents were held constant. The primary efficacy end point was the change in hemoglobin (Hgb) concentration from …

Journal Articles

Increased plasma level of soluble urokinase-type plasminogen activator receptor (suPAR) was associated recently with focal segmental glomerulosclerosis (FSGS). In addition, different clinical studies observed increased concentration of suPAR in various glomerular diseases and in other human pathologies with nephrotic syndromes such as HIV and Hantavirus infection, diabetes and cardiovascular disorders. Here, we show that suPAR induces nephrin down-modulation in human podocytes. This phenomenon is mediated only by full-length suPAR, is time-and dose-dependent and is associated with the suppression of Wilms' tumor 1 (WT-1) transcription factor expression. Moreover, an antagonist of alpha v beta 3 integrin RGDfv blocked suPAR-induced suppression of …

Investigation Of Body Image As A Mediator Of The Effects Of Bowel And Gi Symptoms On Psychological Distress In Female Survivors Of Rectal And Anal Cancer, C. Benedict, V. M. Rodriguez, J. Carter, L. Temple, C. Nelson, K. Duhamel

Journal Articles

PURPOSE: Treatment for rectal and anal cancer (RACa) can result in persistent bowel and gastrointestinal (GI) dysfunction. Body image problems may develop over time and exacerbate symptom-related distress. RACa survivors are an understudied group, however, and factors contributing to post-treatment well-being are not well understood. This study examined whether poorer body image explained the relation between symptom severity and psychological distress. METHODS: Participants (N = 70) completed the baseline assessment of a sexual health intervention study. Bootstrap methods tested body image as a mediator between bowel and GI symptom severity and two indicators of psychological distress (depressive and anxiety symptoms), …

Journal Articles

Intravenous (IV) iron therapy is widely used in iron deficiency anemias when oral iron is not tolerated or ineffective. Administration of IV iron is considered a safe procedure, but severe hypersensitivity reactions (HSRs) can occur at a very low frequency. Recently, new guidelines have been published by the European Medicines Agency (EMA) with the intention of making IV-iron therapy safer; however, the current protocols are still non-specific, non-evidence-based empiric measures which neglect the fact that the majority of IV-iron reactions are not Ig-E-mediated anaphylactic reactions. The field would benefit from new specific and effective methods for the prevention and treatment …

Journal Articles

Chronic lymphocytic leukemia (CLL) is characterized by a progressive accumulation of B lymphocytes. T cell abnormalities are a common feature of CLL and contribute to impaired immune function in these patients. T cells are ineffective in eliminating the leukemic clone and may actually promote tumor growth and survival. Previous work from our laboratory documented elevated circulating levels of IL-17A-producing Th17 cells in CLL patients as compared to healthy age-matched control subjects. These high circulating Th17 levels associated with better prognostic markers and significantly longer overall survival, even among patients whose clones used unmutated IGHVs (U-CLL). Recent studies suggest that Th17 …

In ovarian cancer, multiple attempts to adjust the standard taxane/platinum doublet by adding cytotoxic therapy or varying scheduling, dosage, and delivery have been met with limited success. Alternative methods to improve the grim prognosis of ovarian cancer, including molecular therapies, are currently under investigation. Efforts have been made to study tyrosine kinase inhibitors (including imatinib and pazopanib), Src kinase inhibitors and histone deacetylase inhibitors (HDACi) in combination with taxanes/platinums in order to improve efficacy. Unfortunately, while many pre-clinical and early phase clinical trials argue that the utilization of these molecular targets may enhance survival, only modest benefit has been seen …

Integrating Real Time Data To Improve Outcomes In Acute Kidney Injury, J. S. Hirsch, S. Mohan Jan 2015

Integrating Real Time Data To Improve Outcomes In Acute Kidney Injury, J. S. Hirsch, S. Mohan

Journal Articles

Critically ill patients with acute kidney injury requiring renal replacement therapy have a poor prognosis. Despite well-known factors, which contribute to outcomes, including dose delivery, patients frequently miss the target dose and volume removal. One major barrier to effective care of these patients is the traditional dissociation of dialysis device data from other clinical information systems, notably the electronic health record (EHR). This lack of integration and the resulting manual documentation leads to errors and biases in documentation and missed opportunities to intervene in a timely fashion. This review summarizes the technological advancements facilitating direct connection of dialysis devices to …

Apolipoprotein L1 (Apol1) Variants (Vs) A Possible Link Between Heroin-Associated Nephropathy (Han) And Hiv-Associated Nephropathy (Hivan), X. Lan, T. K. Rao, P. N. Chander, K. Skorecki, P. C. Singhal

Journal Articles

In 1970s, Heroin-associated Nephropathy (HAN), one form of focal and segmental glomerulosclerosis (FSGS), was a predominant cause of End-stage Kidney Disease (ESKD) in African-Americans (AAs). In 1980s, with the surge of Acquired Immune Deficiency Syndrome (AIDS) in AAs, HAN more or less disappeared, and the incidence of Human Immunodeficiency Virus associated Nephropathy (HIVAN) markedly increased. Recent studies in AAs have identified APOL1 variants (Vs) as a major risk factor for the development and progression of non-diabetic kidney diseases including idiopathic FSGS and hypertension-attributed nephrosclerosis. These observations have also offered partial insights into the mechanisms of development, and higher rate of …

Introduction: Moving Beyond Chemotherapy, F. Muggia, E. Teplinsky

Journal Articles

Epithelial ovarian cancer and related cancers arising in extrauterine Mullerian epithelium are generally chemosensitive—particularly to the platinum drugs, cisplatin and carboplatin, that form the backbone of first-line treatments upon diagnosis even at early stages. Doublets of platinums with paclitaxel have represented the standard-of-care since the late 1990s, with further notable advances taking place by intraperitoneal administration (in Gynecologic Oncology Group studies) after optimal surgical cytoreduction is achieved, and by divided doses of paclitaxel (in a Japanese GOG study). Adding another agent to improve on these results has otherwise proven to be quite challenging. Nevertheless, continued forays into introducing ‘targeted therapies’ …

Cardiorenal Syndrome And The Role Of The Bone-Mineral Axis And Anemia, D. M. Charytan, S. Fishbane, J. Malyszko, P. A. Mccullough, D. Goldsmith

Journal Articles

The association between chronic kidney disease (CKD) and cardiovascular disease (CVD) is well established, and there is mounting evidence of interorgan cross talk that may accelerate pathologic processes and the progression of organ dysfunction in both systems. This process, termed cardiorenal syndrome (CRS) by the Acute Dialysis Quality Initiative, is considered a major health problem: patients with CKD and CVD are at much higher risk of mortality than patients with either condition alone. To date, the majority of CRS research has focused on neurohormonal mechanisms and hemodynamic alterations. However, mounting evidence suggests that abnormalities in the normal pathophysiology of the …
