A Guide to Workforce Drug Testing in Iowa, October 13, 2010

The purpose of the State of Iowa’s drug testing law—Iowa Code Section 730.5 (& Administrative Code Section 641)—is to enhance worker safety, by creating workplaces that are free of drugs and substance abuse. One tool available to private sector employers is drug testing (inclusive of alcohol testing), that often is coupled with educational efforts as part of a comprehensive drug-free workplace program. Each employer must first decide if drug and/or alcohol testing is appropriate for them. Under Iowa law, workplace drug or alcohol testing is optional for private sector employers. Federal laws or regulations governing drug or alcohol testing supersede state law in Iowa.

Iowa Pseudoephedrine Control Law, March 22, 2005

This law is intended to reduce the number of hazardous methamphetamine labs in Iowa, by controlling meth cooks’ access to the key meth-making ingredient: pseudoephedrine. In 2004, Iowa law enforcement agencies responded to a record 1,472 meth lab incidents. Below, please find links to: Senate File 169 (Iowa’s pseudoephedrine control law); an Iowa meth fact sheet; a brief overview of the law; and general compliance guidelines for consumers, pharmacies, retailers and law enforcement. Most provisions of this law, pertaining to pseudoephedrine sales, are effective May 21, 2005. However, two other provisions were effective immediately—March 22, 2005—upon the Governor’s signing of this measure into law: (1) removal of exceptions on the Schedule V Controlled Substance status for ephedrine [all ephedrine products now may only be sold in licensed pharmacies…no retail sales of ephedrine permitted]; and (2) addition of a requirement that bailable defendants charged with manufacture, delivery, possession with the intent to deliver, or distribution of methamphetamine, shall, in addition to a substance abuse evaluation, remain under supervision and be required to undergo random drug tests as a condition of release.

Governor's Office of Drug Control Policy Five-Year Strategic Plan July 1, 2003-June 30, 2008

The Office of the Drug Policy Coordinator is established in Chapter 80E of the Code of Iowa. The Coordinator directs the Governor’s Office of Drug Control Policy; coordinates and monitors all statewide counter-drug efforts, substance abuse treatment grants and programs, and substance abuse prevention and education programs; and engages in other related activities involving the Departments of public safety, corrections, education, public health, and human services. The coordinator assists in the development of local and community strategies to fight substance abuse, including local law enforcement, education, and treatment activities. The Drug Policy Coordinator serves as chairperson to the Drug Policy Advisory Council. The council includes the directors of the departments of corrections, education, public health, public safety, human services, division of criminal and juvenile justice planning, and human rights. The Council also consists of a prosecuting attorney, substance abuse treatment specialist, substance abuse prevention specialist, substance abuse treatment program director, judge, and one representative each from the Iowa Association of Chiefs of Police and Peace Officers, the Iowa State Police Association, and the Iowa State Sheriff’s and Deputies’ Association. Council members are appointed by the Governor and confirmed by the Senate. The council makes policy recommendations related to substance abuse education, prevention, and treatment, and drug enforcement. The Council and the Coordinator oversee the development and implementation of a comprehensive State of Iowa Drug Control Strategy. The Office of Drug Control Policy administers federal grant programs to improve the criminal justice system by supporting drug enforcement, substance abuse prevention and offender treatment programs across the state. The ODCP prepares and submits the Iowa Drug and Violent Crime Control Strategy to the U.S. Department of Justice, with recommendations from the Drug Policy Advisory Council. The ODCP also provides program and fiscal technical assistance to state and local agencies, as well as program evaluation and grants management.

Iowa Underage Drinking Plan, 2007

To better address the issue of underage drinking in the State of Iowa, a State Underage Drinking Task Force was formed to research the problem and develop a strategic plan of action. The Task Force was working on the development of goals and actions when the Surgeon General’s Call to Action to Prevent and Reduce Underage Drinking 2007 was released. Due to the similarity in the goals outlined in the Call to Action with those they had developed, the Task Force, along with the DPAC, is recommending that the document be used as the basis for the plan to curb underage drinking. The Call to Action is based on several overarching principles from which its goals and the means for achieving them were derived.

Substance Abuse, Report to the Board of Corrections, 2006

This report, however, goes beyond documentation of the problem. It describes how the Iowa Department of Corrections is addressing substance abuse among the offender population through the provision of treatment, and monitoring for current drug and alcohol usage. All information was obtained from the Iowa Corrections Offender Network (ICON) with many of the reports obtained via the Iowa Justice Data Warehouse.

Synthesis of chemically functionalized superparamagnetic nanoparticles as delivery vectors for chemotherapeutic drugs.

Superparamagnetic iron oxide nanoparticles (SPIONs) are in clinical use for disease detection by MRI. A major advancement would be to link therapeutic drugs to SPIONs in order to achieve targeted drug delivery combined with detection. In the present work, we studied the possibility of developing a versatile synthesis protocol to hierarchically construct drug-functionalized-SPIONs as potential anti-cancer agents. Our model biocompatible SPIONs consisted of an iron oxide core (9-10 nm diameter) coated with polyvinylalcohols (PVA/aminoPVA), which can be internalized by cancer cells, depending on the positive charges at their surface. To develop drug-functionalized-aminoPVA-SPIONs as vectors for drug delivery, we first designed and synthesized bifunctional linkers of varied length and chemical composition to which the anti-cancer drugs 5-fluorouridine or doxorubicin were attached as biologically labile esters or peptides, respectively. These functionalized linkers were in turn coupled to aminoPVA by amide linkages before preparing the drug-functionalized-SPIONs that were characterized and evaluated as anti-cancer agents using human melanoma cells in culture. The 5-fluorouridine-SPIONs with an optimized ester linker were taken up by cells and proved to be efficient anti-tumor agents. While the doxorubicin-SPIONs linked with a Gly-Phe-Leu-Gly tetrapeptide were cleaved by lysosomal enzymes, they exhibited poor uptake by human melanoma cells in culture.

Community-Based Corrections Substance Abuse Treatment for the Higher Risk Offender, Iowa Department of Corrections Performance Audit Report, September 2007

The performance audit conducted by the Department of Management concerned the licensed substance abuse treatment programs in Department of Corrections’ institutions. This report uses the same methodology, modified for community-based corrections populations, to examine the delivery of substance abuse treatment for higher risk offenders under field supervision, and all offenders who were assigned to community corrections residential facilities.

Therapeutic drug monitoring of seven psychotropic drugs and four metabolites in human plasma by HPLC-MS.

A simple and sensitive LC-MS method was developed and validated for the simultaneous quantification of aripiprazole (ARI), atomoxetine (ATO), duloxetine (DUL), clozapine (CLO), olanzapine (OLA), sertindole (STN), venlafaxine (VEN) and their active metabolites dehydroaripiprazole (DARI), norclozapine (NCLO), dehydrosertindole (DSTN) and O-desmethylvenlafaxine (OVEN) in human plasma. The above mentioned compounds and the internal standard (remoxipride) were extracted from 0.5 mL plasma by solid-phase extraction (mix mode support). The analytical separation was carried out on a reverse phase liquid chromatography at basic pH (pH 8.1) in gradient mode. All analytes were monitored by MS detection in the single ion monitoring mode and the method was validated covering the corresponding therapeutic range: 2-200 ng/mL for DUL, OLA, and STN, 4-200 ng/mL for DSTN, 5-1000 ng/mL for ARI, DARI and finally 2-1000 ng/mL for ATO, CLO, NCLO, VEN, OVEN. For all investigated compounds, good performance in terms of recoveries, selectivity, stability, repeatability, intermediate precision, trueness and accuracy, was obtained. Real patient plasma samples were then successfully analysed.

Risk of falls and major bleeds in patients on oral anticoagulation therapy.

BACKGROUND: The risk of falls is the most commonly cited reason for not providing oral anticoagulation, although the risk of bleeding associated with falls on oral anticoagulants is still debated. We aimed to evaluate whether patients on oral anticoagulation with high falls risk have an increased risk of major bleeding. METHODS: We prospectively studied consecutive adult medical patients who were discharged on oral anticoagulants. The outcome was the time to a first major bleed within a 12-month follow-up period adjusted for age, sex, alcohol abuse, number of drugs, concomitant treatment with antiplatelet agents, and history of stroke or transient ischemic attack. RESULTS: Among the 515 enrolled patients, 35 patients had a first major bleed during follow-up (incidence rate: 7.5 per 100 patient-years). Overall, 308 patients (59.8%) were at high risk of falls, and these patients had a nonsignificantly higher crude incidence rate of major bleeding than patients at low risk of falls (8.0 vs 6.8 per 100 patient-years, P=.64). In multivariate analysis, a high falls risk was not statistically significantly associated with the risk of a major bleed (hazard ratio 1.09; 95% confidence interval, 0.54-2.21). Overall, only 3 major bleeds occurred directly after a fall (incidence rate: 0.6 per 100 patient-years). CONCLUSIONS: In this prospective cohort, patients on oral anticoagulants at high risk of falls did not have a significantly increased risk of major bleeds. These findings suggest that being at risk of falls is not a valid reason to avoid oral anticoagulants in medical patients.

Differential involvement of MEK kinase 1 (MEKK1) in the induction of apoptosis in response to microtubule-targeted drugs versus DNA damaging agents.

MEK kinase 1 (MEKK1) is a 196-kDa enzyme that is involved in the regulation of the c-Jun N-terminal kinase (JNK) pathway and apoptosis. In cells exposed to genotoxic agents including etoposide and cytosine arabinoside, MEKK1 is cleaved at Asp874 by caspases. The cleaved kinase domain of MEKK1, itself, stimulates caspase activity leading to apoptosis. Kinase-inactive MEKK1 expressed in HEK293 cells effectively blocks genotoxin-induced apoptosis. Treatment of cells with taxol, a microtubule stabilizing agent, did not induce MEKK1 cleavage in cells, and kinase-inactive MEKK1 expression failed to block taxol-induced apoptosis. MEKK1 became activated in HEK293 cells exposed to taxol, but in contrast to etoposide-treatment, taxol failed to increase JNK activity. Taxol treatment of cells, therefore, dissociates MEKK1 activation from the regulation of the JNK pathway. Overexpression of anti-apoptotic Bcl2 blocked MEKK1 and taxol-induced apoptosis but did not block the caspase-dependent cleavage of MEKK1 in response to etoposide. This indicates Bcl2 inhibition of apoptosis is, therefore, downstream of caspase-dependent MEKK1 cleavage. The results define the involvement of MEKK1 in the induction of apoptosis by genotoxins but not microtubule altering drugs.

How to keep the brain awake? : pharmacogenomics and aging effects on sleep-wake regulation in inbred mice

ABSTRACT : Genetic approach in the sleep field is at the beginning of its wide expansion. Transitions between sleep and wakefulness, and the maintenance of these states are driven by complex neurobiologic mechanisms with reciprocal interactions. Impairment in both transitions and maintenance of behavioral states leads to debilitating conditions. The major symptom being excessive daytime sleepiness, characterizing most sleep disorders but also a wide variety of psychiatric and neurologic disorders, as well as the elderly. Until now, most wake-promoting drugs available directly (e.g., amphetamines and possibly modafinil) or indirectly (e.g., caffeine) provokes dopamine release which is believed to influence the abuse potential of these drugs. The effects of genetic components were assessed here, on drug-induced wakefulness and age-related sleep changes in three inbred mouse strains [AKR/J, C57BL/6J, DBA/2J] that differ in their major sleep phenotypes. Three wake-promoting drugs were used; d-amphetamine, a classical stimulant, modafinil, the most widely-prescribed stimulant, and YKP-10A, a novel wake-promoting agent with antidepressant proprieties. Electrical activity (Electroencephalogram) and gene expression of the brain were assessed and indicate a highly genotype-dependant response to wake promotion and subsequent recovery sleep. Aging effects on sleep-wake regulation were also strongly influenced by genetic determinants. By assessing the age-dependant effects at several time points (from 3 months to 2 years old mice), we found a strong genetic effect on vigilance states. These studies demonstrate a critical role for genetic factors neglected till now in the fields of pharmacology and aging effects on vigilance states.
