REVIEW
Ankur S Narain, Fady Y Hijji, Kelly H Yom, Krishna T Kudaravalli, Kern Singh
BACKGROUND CONTEXT: Cervical disc arthroplasty (CDA) is an emerging technique for the treatment of cervical degenerative disease. Multiple studies have investigated the outcomes of CDA, particularly in comparison to cervical arthrodesis techniques such as anterior cervical discectomy and fusion (ACDF). As many entities have financial interests in CDA implants, it is imperative to consider the influence of conflicts of interest on the results of studies investigating the efficacy of CDA...

Many different text features influence text readability and content comprehension. Negation is commonly suggested as one such feature, but few general-purpose tools exist to discover negation and studies of the impact of negation on text readability are rare. In this paper, we introduce a new negation parser (NegAIT) for detecting morphological, sentential, and double negation. We evaluated the parser using a human annotated gold standard containing 500 Wikipedia sentences and achieved 95%, 89% and 67% precision with 100%, 80%, and 67% recall, respectively...

To accurately mimic the native tissue environment, tissue engineered scaffolds often need to have a highly controlled and varied display of three-dimensional (3D) architecture and geometrical cues. Additive manufacturing in tissue engineering has made possible the development of complex scaffolds that mimic the native tissue architectures. As such, architectural details that were previously unattainable or irreproducible can now be incorporated in an ordered and organized approach, further advancing the structural and chemical cues delivered to cells interacting with the scaffold...

OBJECTIVE: This is a nationwide query into surgical management techniques for tethered cord syndrome, focusing on patient demographic, hospital characteristics, and treatment outcomes. Our hypothesis is that detethering vs. fusion for TCS results in different in-hospital complications. MATERIALS AND METHODS: Retrospective review of the Nationwide Inpatient Sample 2001-2010. Inclusion: TCS discharges undergoing detethering or fusion. Sub-analysis compared TCS cases by age (pediatric [≤9years] vs...

PURPOSE: Management guidelines for infants with chylothorax lack substantial evidence. We sought to identify variables that impact outcomes in these patients in order to develop an evidence-based management algorithm. METHODS: We retrospectively reviewed the medical records of all infants diagnosed with chylothorax from June 2005 to December 2014 at our institution. Data collected included demographics, chest tube output (CTO), medical and dietary interventions, surgical procedures, and absolute lymphocyte count (ALC)...

BACKGROUND: The purpose of this study is to evaluate perfusion related complications in bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction based on perforator selection. METHODS: A retrospective review of a prospectively maintained database was performed on all patients undergoing bilateral DIEP flap reconstruction at a single institution between 2004-2014. The hemiflaps were separated into three cohorts based on perforator location: lateral row only, medial row only, and medial plus lateral row...

Toxoplasma gondii has been suggested as an important opportunistic pathogen in immunocompromised patients. We conducted a global meta-analysis to assess the prevalence and odds ratios (ORs) of T. gondii infection in immunocompromised individuals. Electronic databases were reviewed for T. gondii infection in HIV/AIDS patients, cancer patients, and transplant recipients, and meta-analyses were conducted to calculate overall estimated prevalence and ORs using random or fixed-effects models. Totally, 72 eligible studies were included...

Infectious encephalitis is a severe disease leading to a high mortality and morbidity. The most frequent causes include Herpes simplex virus, Varicella Zoster virus, Listeria monocytogenes, and Mycobacterium tuberculosis. Urgent treatment is required (anti-infective therapy and nonspecific supportive care). The aim of this study was to define treatment strategy, empirical and after microbiological documentation at 48hours, through a systematic literature review.

Recent success in cancer immunotherapy (anti-CTLA-4, anti-PD1/PD-L1) has confirmed the hypothesis that the immune system can control many cancers across various histologies, in some cases producing durable responses in a way not seen with many small-molecule drugs. However, only less than 25% of all patients do respond to immuno-oncology drugs and several resistance mechanisms have been identified (e.g. T-cell exhaustion, overexpression of caspase-8 and β-catenin, PD-1/PD-L1 gene amplification, MHC-I/II mutations)...

Publications reporting concentrations of caffeine in postmortem blood were reviewed if the cause of death was attributed to overdosing (poisoning) with drugs. Age and gender of the deceased, the manner of death (accident, suicide or undetermined) and types of co-ingested drugs were evaluated in relation to the concentrations of caffeine in blood (N = 51). The mean age (±SD) of the victims was 39 ± 17.8 years (range 18-84 years) and most were female (N = 31 or 61%). The difference in mean age of males (42 ± 17...

PURPOSE: To determine whether an oral effervescent agent improves magnetic resonance cholangiography (MRC) images, both qualitatively and quantitatively, in potential live liver donors. MATERIALS AND METHODS: This retrospective study was approved by the Institutional Review Board, and informed consent was waived. Seventy potential liver donors underwent 2D MRC before and after administration of an oral effervescent agent. One radiologist measured relative contrast ratio (rC) and relative signal intensity (rS) for right and left intrahepatic ducts (RHD and LHD), and common hepatic duct (CHD)...

OBJECTIVE: The purpose of this study is to evaluate the utility of combined PET/CT for the detection of early local tumor progression after cryoablation of bone metastases. MATERIALS AND METHODS: A retrospective single-institution review revealed 61 consecutive patients with 80 separate bone metastases treated with cryoablation who were evaluated with a preablation PET/CT and at least two postablation PET/CT examinations between September 2007 and July 2015. Patients were excluded if they had local therapy or pathologic fracture after ablation...

INTRODUCTION: The CellaVision™DM96 is a digital pattern recognition system that classifies white blood cells. The aim of this study was to evaluate whether the CellaVision preclassification feature, without a subsequent re-classification, was a sufficient approach to follow up flags reported by Sysmex XE-5000. METHODS: Pairs of blood smears from 400 samples reported with suspect flags were examined using conventional microscopy and the CellaVision features. The effect of pre- vs...

Hypertension is the leading cause of cardiovascular disease in the United States and worldwide. It also provides a useful model for team-based chronic disease management. This article describes the M.A.P. checklists: a framework to help practice teams summarize best practices for providing coordinated, evidence-based care to patients with hypertension. Consisting of three domains-Measure Accurately; Act Rapidly; and Partner With Patients, Families, and Communities-the checklists were developed by a team of clinicians, hypertension experts, and quality improvement experts through a multistep process that combined literature review, iterative feedback from a panel of internationally recognized experts, and pilot testing among a convenience sample of primary care practices in two states...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) effectively treats obesity and gastroesophageal reflux disease (GERD). As more surgeons recommend RYGB to treat GERD in patients with obesity, there are concerns about this approach in patients with previous non-bariatric foregut surgery. This study aims to evaluate the effect of previous non-bariatric foregut surgery on subsequent RYGB. METHODS: Retrospective review of 2089 patients undergoing RYGB between January 1985 and June 2015 was conducted to identify all patients with previous non-bariatric foregut surgery...

REVIEW

Diabetes in whites of European descent with hemochromatosis was first attributed to pancreatic siderosis. Later observations revealed that the pathogenesis of diabetes in HFE hemochromatosis is multifactorial and its clinical manifestations are heterogeneous. Increased type 2 diabetes risk in HFE hemochromatosis is associated with one or more factors, including abnormal iron homeostasis and iron overload, decreased insulin secretion, cirrhosis, diabetes in first-degree relatives, increased body mass index, insulin resistance, and metabolic syndrome...
