Comparison of the glomerular filtration rate in children by the new revised Schwartz formula and a new generalized formula.

The most widely used formula for estimating glomerular filtration rate (eGFR) in children is the Schwartz formula. It was revised in 2009 using iohexol clearances with measured GFR (mGFR) ranging between 15 and 75 ml/min × 1.73 m(2). Here we assessed the accuracy of the Schwartz formula using the inulin clearance (iGFR) method to evaluate its accuracy for children with less renal impairment comparing 551 iGFRs of 392 children with their Schwartz eGFRs. Serum creatinine was measured using the compensated Jaffe method. In order to find the best relationship between iGFR and eGFR, a linear quadratic regression model was fitted and a more accurate formula was derived. This quadratic formula was: 0.68 × (Height (cm)/serum creatinine (mg/dl))-0.0008 × (height (cm)/serum creatinine (mg/dl))(2)+0.48 × age (years)-(21.53 in males or 25.68 in females). This formula was validated using a split-half cross-validation technique and also externally validated with a new cohort of 127 children. Results show that the Schwartz formula is accurate until a height (Ht)/serum creatinine value of 251, corresponding to an iGFR of 103 ml/min × 1.73 m(2), but significantly unreliable for higher values. For an accuracy of 20 percent, the quadratic formula was significantly better than the Schwartz formula for all patients and for patients with a Ht/serum creatinine of 251 or greater. Thus, the new quadratic formula could replace the revised Schwartz formula, which is accurate for children with moderate renal failure but not for those with less renal impairment or hyperfiltration.

2008 Iowa Youth Survey State of Iowa Results, Revised June 2009

In September and October of 2008, the Iowa Department of Public Health (IDPH) collaborated with schools in Iowa to conduct the 2008 Iowa Youth Survey (IYS). The 2008 IYS is the twelfth in a series of surveys that have been completed every three years since 1975. The survey is conducted with students in grades 6, 8, and 11 attending Iowa public and private schools. The IYS includes questions about students’ behaviors, attitudes, and beliefs, as well as their perceptions of peer, family, school, neighborhood, and community environments.

2005 Iowa Youth Survey State of Iowa Results, Revised December 2006

The 2005 Iowa Youth Survey (IYS) State of Iowa report was designed to help state-level planners identify youth development-related needs, develop relevant programs, and assess the outcomes of those programs. These data can help you better understand our youth and their needs. They can also help you assess the strengths and weaknesses of our schools, families, and communities from the young person’s perspective. In addition, the data in this report help the state obtain funds for a wide variety of programs. At every step of the process–from needs identification, to program development and implementation, to program assessment–the 2005 IYS data will prove to be a valuable resource. The state report can also help Iowa’s schools, area education agencies, and counties assess their relative strengths and weaknesses. The grades 6, 8, and 11, as well as male and female percentages reported in district-level, AEA-level, county-level, and other 2005 IYS reports can be compared with the respective state report percentages. The higher the proportion of students in each of these columns that completed usable IYS questionnaires, the more likely the comparisons with the state report percentages will be unbiased. Such comparisons should be considered exploratory, but for the most part are likely to be useful.

Alternatives to Guardianship and Conservatorship for Adults in Iowa, Revised 2006

Independence, respect, and equality are values important to all people. These values help define the concepts of autonomy (independence and freedom) and self-determination (the right to make decisions for one’s self). Because these rights are so valued in our society and are something that most of us would value for ourselves, the “least restrictive alternative” should always be considered before taking away a person’s civil and legal rights to make decisions for him or herself. The least restrictive alternative is an option, which allows a person to keep as much autonomy, and self-determination as possible while providing only the level of protection and supervision that is necessary. Some examples may include: representative payee for certain government benefit checks, joint bank accounts or advance directives for health care.

Power of Attorney Handbook, June 2006, revised

This booklet is designed to assist those who have been appointed as an attorney-in-fact, those who are considering the need for a power of attorney, or those who have an interest in the subject. This is a general overview of the laws governing powers of attorney and, like most general overviews it will apply in most situations, but not all. Small differences and individual circumstances can be very important in resolving legal problems and the general guidance provided by this booklet cannot take such differences into account. Keep in mind that the laws continually change and information in this booklet is not designed to take the place of legal counsel.

I-74 Iowa/Illinois Corridor Study Aesthetic Design Guideline April 6, 2009

The I-74 Aesthetic Design Guideline (ADG) document has two primary goals: To establish and identify an overall design theme To prioritize enhancement opportunities within the framework of corridor elements The recommendations of this report have been developed based on an “unconstrained” framework for future corridor–wide enhancements. Future funding availability, along with the recommendations of this report, will guide the final design process. ADG Future Uses: This document is intended to be used as a reference to future processes in the following ways: Guidance for I-74 final design teams Reference document for future local community redevelopment initiatives Inspiration for identification and development of other I-74 corridor aesthetic enhancement opportunities Process: As illustrated in Figure 1.3, the overall process for corridor aesthetics began traditionally with inventory and identification of potential aesthetic applications. The ADG does not document all the reports and presentations related to these early design stages, but has incorporated these efforts into the design theme, guiding principles and prioritized enhancements shown on the following pages of this report. The I-74 final design phase will incorporate these recommendations into the project. The consultant design team and representatives of the DOTs have worked with the CAAT members to facilitate community input and have helped develop recommendations for improving I-74 corridor aesthetics. CAAT recommendations have been advanced to the I-74 Advisory Committee for review and endorsement. Both DOTs have reviewed the CAAT recommendations and have endorsed the contents of this report. Figure 1.4 illustrates the status of corridor aesthetic design development. As of the date of this report, aesthetic design is approximately 50% complete. Future detailed design, cost evaluation, feasibility and prioritizations all need to occur for this process to be successfully completed.

I-74 Iowa-Illinois Corridor Study, Vol 3, Fall 2003

The I-74 Iowa-Illinois Corridor Study has been progressing since the last newsletter and the Public Information Meetings in July of 2002, and the Advisory Committee has been involved in every step. Our goal has been and continues to be ensuring that community priorities and goals are reflected in the I-74 project, and that local concerns are considered.

Feasibility Study on Proposed Amtrak service from Chicago, to Iowa City, Iowa via Quad Cities, December 5, 2007

Soon after the Illinois Department of Transportation (“Ill. DOT”) requested Amtrak to conduct a feasibility study on proposed Amtrak service between Chicago and the Illinois Quad Cities, the Iowa Department of Transportation (“Iowa DOT”) asked that the study be extended to Iowa City and later to Des Moines. This report examines the feasibility of extending service to Iowa City. The completed report for the proposed Chicago – Quad Cities’ service was delivered to Ill. DOT in early January 2008. It assumes a stand-alone train operation strictly within the State of Illinois and makes no reference to extending the service into the State of Iowa. Therefore, there is no discussion about potential cost sharing allocations for capital improvements or operating losses between the two states which will become a matter of future negotiations between the two jurisdictions. That being said, this report on extending the service to Iowa City is simply an addendum to the Quad Cities report and covers such topics as additional capital infrastructure improvements that would be required in Iowa, impacts on operating expenses, revised ridership and revenue projections, and the like. With one minor exception, the recommended level of capital improvements within Illinois will still be required if the service to Iowa City is initiated. It is thus important for the readers of this report to refer to the Illinois study for detailed information on that state’s portion of the route alternatives.
