    Research Original Investigation Triheptanoin for Glucose Transporter Type I Deficiency (G1D) Modulation of Human Ictogenesis, Cerebral Metabolic Rate, and Cognitive Indices by a Food Supplement Juan M. Pascual, MD, PhD; Peiying Liu, PhD; Deng Mao, BS; Dorothy I. Kelly, MA; Ana Hernandez, MS; Min Sheng, PhD; Levi B. Good, PhD; Qian Ma, MD, PhD; Isaac Marin-Valencia, MD, MS; Xuchen Zhang, MD; Jason Y. Park, MD, PhD; Linda S. Hynan, PhD; Peter Stavinoha, PhD; Charles R. Roe, MD; Hanzhang Lu, PhD Supplemental content at IMPORTANCE Disorders of brain metabolism are multiform in their mechanisms and jamaneurology.com manifestations, many of which remain insufficiently understood and are thus similarly treated. Glucose transporter type I deficiency (G1D) is commonly associated with seizures and with electrographic spike-waves. The G1D syndrome has long been attributed to energy (ie, adenosine triphosphate synthetic) failure such as that consequent to tricarboxylic acid (TCA) cycle intermediate depletion. Indeed, glucose and other substrates generate TCAs via anaplerosis. However, TCAs are preserved in murine G1D, rendering energy-failure inferences premature and suggesting a different hypothesis, also grounded on our work, that consumption of alternate TCA precursors is stimulated and may be detrimental. Second, common ketogenic diets lead to a therapeutically counterintuitive reduction in blood glucose available to the G1D brain and prove ineffective in one-third of patients. OBJECTIVE To identify the most helpful outcomes for treatment evaluation and to uphold (rather than diminish) blood glucose concentration and stimulate the TCA cycle, including anaplerosis, in G1D using the medium-chain, food-grade triglyceride triheptanoin. DESIGN, SETTING, AND PARTICIPANTS Unsponsored, open-label cases series conducted in an academic setting.

  • Chemoprevention in Kidney Cancer by Madhur Nayan
    Chemoprevention in Kidney Cancer by Madhur Nayan A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy in Clinical Epidemiology, Graduate Department of Health Policy, Management, and Evaluation, in the University of Toronto © Copyright by Madhur Nayan, 2017 THESIS ABSTRACT Thesis Title: Chemoprevention in kidney cancer Degree: Doctor of Philosophy (PhD) in Clinical Epidemiology Year of Convocation: 2017 Student: Madhur Nayan Graduate Department: Health Policy, Management and Evaluation University: University of Toronto Background: This thesis is a composition of three studies that explore the role of statins in kidney cancer. Furthermore, I evaluate the potential for different interpretations from the same data depending on the method of classifying medication use. Methods: The first study was a population-based case-control study evaluating the association of statin use with risk of incident kidney cancer. The second study was a systematic review and meta-analysis reviewing the current evidence relating statins with kidney cancer survival outcomes. The final study was a population-based cohort study evaluating the association of statin use with survival. In the observational studies, I used fractional polynomials for the primary analysis to allow for a non-linear relationship between cumulative exposure and the risk of the outcome. I also compared risk estimates obtained by different methods of classifying medication exposure. Results: The population-based case-control study included 10,377 incident cases of kidney cancer and 35,939 matched controls. Increasing cumulative use of statins was not associated with kidney cancer risk. I identified 12 studies for inclusion in the systematic review and meta- analysis and found that statin use was significantly associated with markedly improved cancer- specific and overall survival.
