Progressive Multifocal Leukoencephalopathy in a HIV Negative, Immunocompetent Patient.

Case Rep Neurol Med

August 2016

Columbia College of Physicians and Surgeons, Columbia University Medical Center, 161 Fort Washington Avenue, New York, NY 10032, USA.

Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating disease most common in immunodeficient patients. It occurs due to reactivation of the John Cunningham Virus (JCV) and carries a poor prognosis, with a median life expectancy of 6 months. We report a case of a 66-year-old man with a history of HCV related cirrhosis (HCV) and hepatocellular carcinoma (HCC) who was found to have PML in the setting of a negative viral load in the CSF and a CD4+ >200.

Reduced Functional Connectivity within the Mesocorticolimbic System in Substance Use Disorders: An fMRI Study of Puerto Rican Young Adults.

Front Behav Neurosci

June 2016

Department of Psychiatry, Columbia College of Physicians and Surgeons, Columbia UniversityNew York, NY, USA; Department of Psychiatry, New York State Psychiatric InstituteNew York, NY, USA.

Studies of the mesocorticolimbic reward system (MCLS) and its relationship with impulsivity and substance use disorders (SUD) have largely focused on individuals from non-minority backgrounds. This represents a significant gap in the literature particularly for minority populations who are disproportionately affected by the consequences of SUD. Using resting-state functional MRI (fMRI), we examined the coherence of neural activity, or functional connectivity, within the brain's MCLS in 28 young adult Puerto Ricans (ages 25-27) who were part of a population-based cohort study.

Objectives: Evaluation for a potentially life-threatening cardiac event in the emergency department (ED) is a stressful experience that can result in symptoms of post-traumatic stress disorder, which are associated with increased risk of morbidity and mortality in patients. No study has tested whether good clinician-patient communication in the ED is associated with better psychological outcomes in these individuals and whether it can mitigate other risk factors for post-traumatic stress symptoms (PSS) such as perception of life threat and vulnerability in the ED.

Methods: Data were analysed from 474 participants in the Reactions to Acute Care and Hospitalization (REACH) study, an observational cohort study of ED predictors of medical and psychological outcomes after evaluation for suspected acute coronary syndrome.

Nonalcoholic Fatty Liver Disease: Lipids and Insulin Resistance.

Clin Liver Dis

May 2016

Division of Digestive and Liver Diseases, Department of Medicine, Columbia College of Physicians and Surgeons, Columbia University Medical Center, 650 West 168 Street, New York, NY 10032, USA.

Obesity and its major comorbidities, including type 2 diabetes mellitus, nonalcoholic fatty liver disease (NAFLD), obesity cardiomyopathy, and certain cancers, have caused life expectancy in the United States to decline in recent years. Obesity is the increased accumulation of triglycerides (TG), which are synthesized from glycerol and long-chain fatty acids (LCFA) throughout the body. LCFA enter adipocytes, hepatocytes, and cardiomyocytes via specific, facilitated transport processes.

Background Context: The non-response rates are as high as 20% to 50% after 5 years of follow-up in adult spinal deformity (ASD) surgery. Minimizing loss to follow-up is essential to protect the quality of data in long-term studies. Phone and internet administration of outcomes instruments has grown in popularity and has been found to not only provide a convenient way of collecting data, but also show improved response rates.

Humans have been argued to be biologically adapted to a cooked diet, but this hypothesis has not been tested at the molecular level. Here, we combine controlled feeding experiments in mice with comparative primate genomics to show that consumption of a cooked diet influences gene expression and that affected genes bear signals of positive selection in the human lineage. Liver gene expression profiles in mice fed standardized diets of meat or tuber were affected by food type and cooking, but not by caloric intake or consumer energy balance.

Limited cell numbers in umbilical cord blood (UCB) grafts present a major impediment to favorable outcomes in adult transplantation, largely related to delayed or failed engraftment. The advent of UCB transplantation (UCBT) using two grafts successfully circumvents this obstacle, despite the engraftment of only one unit. Preclinical models suggested that the addition of UCB T cells at the time of transplant can enhance engraftment.

Unlabelled: In 1988, the first contrast agent specifically designed for magnetic resonance imaging (MRI), gadopentetate dimeglumine (Magnevist(®)), became available for clinical use. Since then, a plethora of studies have investigated the potential of MRI contrast agents for diagnostic imaging across the body, including the central nervous system, heart and circulation, breast, lungs, the gastrointestinal, genitourinary, musculoskeletal and lymphatic systems, and even the skin. Today, after 25 years of contrast-enhanced (CE-) MRI in clinical practice, the utility of this diagnostic imaging modality has expanded beyond initial expectations to become an essential tool for disease diagnosis and management worldwide.

Multi-Scale Entrainment of Coupled Neuronal Oscillations in Primary Auditory Cortex.

Front Hum Neurosci

December 2015

Cognitive Neuroscience and Schizophrenia Program, Nathan Kline Institute Orangeburg, NY, USA ; Department of Psychiatry, NYU School of Medicine New York, NY, USA.

Earlier studies demonstrate that when the frequency of rhythmic tone sequences or streams is task relevant, ongoing excitability fluctuations (oscillations) of neuronal ensembles in primary auditory cortex (A1) entrain to stimulation in a frequency dependent way that sharpens frequency tuning. The phase distribution across A1 neuronal ensembles at time points when attended stimuli are predicted to occur reflects the focus of attention along the spectral attribute of auditory stimuli. This study examined how neuronal activity is modulated if only the temporal features of rhythmic stimulus streams are relevant.
