[EX Q]: In the 20th century industrialized nations have become afflicted with an unprecedented pandemic of increased adiposity. In the United States, the epicenter of the epidemic, over 2/3 of the population, is overweight and 1 of every 6 Americans carries the diagnosis of metabolic syndrome. Although genes determine susceptibility to environmental factors, the epidemic is clearly due to increased consumption of calorie-dense, highly lipogenic foods, coupled with a marked decrease in physical exertion resulting from modern technologies. If this lifestyle continues, morbid consequences are virtually inevitable. They include type II diabetes and a cluster of disorders known as "the metabolic syndrome" usually appearing in middle age. The morbid consequences of the chronic caloric surplus are buffered before middle age by the partitioning of these calories as fat in the adipocyte compartment which is specifically designed to store triglycerides. Leptin has been proposed as the major hormonal regulator of the partitioning of surplus calories. However, multiple factors can determine the storage capacity of the fat tissue and when it is exceeded ectopic lipid deposition begins. The organs affected in metabolic syndrome include skeletal muscle, liver, heart and pancreas, which are now known to contain abnormal levels of triglycerides. While neutral fat is probably harmless, it is an index of ectopic lipid overload. Fatty acid derivatives can interfere with the function of the cell and ultimately lead to its demise through lipoapoptosis, the consequences of which are gradual organ failure.

[EX Q]: Two synthetic peripheral nerve myelin P0 protein peptides, an immunodominant (amino acids 180-199) and a cryptic (amino acids 56-71) one, induced an acute or chronic course of experimental autoimmune neuritis (EAN) in Lewis rats, when given at low dose (50-100 microg/rat) or high dose (250 microg/rat), respectively. Corresponding to the different clinical course, pathological changes and immune responses were found: (1) Onset of clinical signs of P0 peptide 56-71 (P0 56-71) induced EAN was 1-3 days later than in P0 peptide 180-199 (P0 180-199) induced EAN at all immunizing doses, whereas the peak of the disease occurred at a similar time point post immunization (p.i.), i.e. at days 14-16 p.i. in P0 56-71 induced EAN and at day 16 p.i. in P0 180-199 induced EAN. (2) Intramolecular epitope spreading as assessed by delayed type hypersensitivity response occurred in P0 56-71 induced EAN at both low and high antigen doses and in P0 180-199 induced EAN at high antigen dose (250 microg/rat) only. (3) P0 180-199 stimulated higher levels of interferon-gamma production in P0 180-199 induced EAN than in P0 56-71 induced EAN and vice versa. (4) Histopathologic evaluation revealed a similar grade of mononuclear cell infiltration in the sciatic nerves of both types of EAN, but more severe demyelination was found in P0 180-199 induced EAN compared to P0 56-71 induced EAN. The results support the hypothesis that high dose autoantigen immunization induces extensive determinant spreading and chronic course of autoimmune diseases.

[EX Q]: ContextChronic hepatitis C is the leading cause for liver transplantation in the United States. Intravenous drug use, the major risk factor, accounts for approximately 60% of hepatitis C virus transmission. Information from the United Network of Organ Sharing (UNOS) does not address substance use among liver transplantation patients. ObjectiveTo identify addiction-related criteria for admission to the UNOS liver transplantation waiting list and posttransplantation problems experienced by patients who are prescribed maintenance methadone. Design, Setting, and ParticipantsMail survey of all 97 adult US liver transplantation programs (belonging to UNOS) in March 2000 with telephone follow-up conducted in May and June 2000.Main Outcome MeasuresPrograms' acceptance and management of patients with past or present substance use disorder. ResultsOf the 97 programs surveyed, 87 (90%) responded. All accept applicants with a history of alcoholism or other addictions, including heroin dependence. Eighty-eight percent of the responding programs require at least 6 months of abstinence from alcohol; 83% from illicit drugs. Ninety-four percent have addiction treatment requirements. Consultations from substance abuse specialists are obtained by 86%. Patients receiving methadone maintenance are accepted by 56% of the responding programs. Approximately 180 patients receiving methadone maintenance are reported to have undergone liver transplantation. ConclusionsMost liver transplantation programs have established policies for patients with substance use disorders. Opiate-dependent patients receiving opiate replacement therapy seem underrepresented in transplantation programs. Little anecdotal evidence for negative impact of opiate replacement therapy on liver transplantation outcome was found. Policies requiring discontinuation of methadone in 32% of all programs contradict the evidence base for efficacy of long-term replacement therapies and potentially result in relapse of previously stable patients.
