Background: Obstructive sleep apnea (OSA) is an important clinical condition. Eligibility for treatment usually depends on disease severity, measured as the apnea-hypopnea index (AHI), equal to the sum of apneas plus hypopneas per hour of sleep. There is divergence on scoring rules for hypopneas between the recommendations of the American Academy of Sleep Medicine (AASM) and the Center for Medicare Services (CMS), the latter being more restrictive.

Article Synopsis
  • Familial acute myeloid leukemia is linked to specific genetic mutations, particularly in CEBPA, with a focus on a unique Q311P mutation identified in a study involving a large family.
  • Using advanced techniques like whole exome sequencing and protein modeling, researchers found that the Q311P mutation disrupts the DNA-binding ability of the CEBPA protein.
  • The study also noted incomplete penetrance of this mutation, suggesting that not all carriers will develop leukemia despite having the genetic mutation.

Cannabinoids in Medical Practice.

Cannabis Cannabinoid Res

January 2016

Department of Psychiatry, David Geffen UCLA School of Medicine, Los Angeles, California.

Many patients with chronic medical illnesses use cannabinoids. There are two FDA-approved cannabinoid products, whereas medical marijuana purchased at legal dispensaries is not FDA regulated and may contain uncertain concentrations of various compounds. Cannabinoids have shown efficacy in treating chemotherapy-related nausea and vomiting, poor appetite in advanced HIV, some pain states, and multiple sclerosis-associated spasticity.

EGFR Mutation Promotes Glioblastoma through Epigenome and Transcription Factor Network Remodeling.

Mol Cell

October 2015

Ludwig Institute for Cancer Research, La Jolla, CA 92093, USA; Department of Pathology, UCSD School of Medicine, La Jolla, CA 92093, USA; Moores Cancer Center, UCSD School of Medicine, La Jolla, CA 92093, USA. Electronic address:

Epidermal growth factor receptor (EGFR) gene amplification and mutations are the most common oncogenic events in glioblastoma (GBM), but the mechanisms by which they promote aggressive tumor growth are not well understood. Here, through integrated epigenome and transcriptome analyses of cell lines, genotyped clinical samples, and TCGA data, we show that EGFR mutations remodel the activated enhancer landscape of GBM, promoting tumorigenesis through a SOX9 and FOXG1-dependent transcriptional regulatory network in vitro and in vivo. The most common EGFR mutation, EGFRvIII, sensitizes GBM cells to the BET-bromodomain inhibitor JQ1 in a SOX9, FOXG1-dependent manner.

In this review, a companion piece to our recent examination of choroid plexus (CP), the organ that secretes the cerebrospinal fluid (CSF), we focus on recent information in the context of reliable older data concerning the composition and functions of adult human CSF. To accomplish this, we define CSF, examine the methodology employed in studying the CSF focusing on ideal or near ideal experiments and discuss the pros and cons of several widely used analogical descriptions of the CSF including: the CSF as the "third circulation," the CSF as a "nourishing liquor," the similarities of the CSF/choroid plexus to the glomerular filtrate/kidney and finally the CSF circulation as part of the "glymphatic system." We also consider the close interrelationship between the CSF and extracellular space of brain through gap junctions and the paucity of data suggesting that the cerebral capillaries secrete a CSF-like fluid.

Glucose-dependent acetylation of Rictor promotes targeted cancer therapy resistance.

Proc Natl Acad Sci U S A

July 2015

Ludwig Institute for Cancer Research, University of California San Diego, La Jolla, CA 92093; Moores Cancer Center, University of California San Diego, La Jolla, CA 92093; Department of Pathology, University of California San Diego, La Jolla, CA 92093

Cancer cells adapt their signaling in response to nutrient availability. To uncover the mechanisms regulating this process and its functional consequences, we interrogated cell lines, mouse tumor models, and clinical samples of glioblastoma (GBM), the highly lethal brain cancer. We discovered that glucose or acetate is required for epidermal growth factor receptor vIII (EGFRvIII), the most common growth factor receptor mutation in GBM, to activate mechanistic target of rapamycin complex 2 (mTORC2) and promote tumor growth.

Exercise in the management of persons with multiple sclerosis.

Ther Adv Neurol Disord

May 2015

Professor of Clinical Neurology, David Geffen UCLA School of Medicine, Los Angeles, CA 90095, USA.

For decades, persons with multiple sclerosis (MS) were counseled to avoid excessive physical activity and exercise because of concerns about worsening disease activity. Recent studies indicate that, not only can those with MS tolerate physical exercise, but that it is helpful in managing symptoms, preventing complications and comorbidities, and may possibly have neuroprotective actions. This article reviews previous studies on the effects of different exercise protocols in people with MS, and provides summaries of suggested exercise regimens that may be appropriate and beneficial for this patient population.
