2014 Iowa Commercial Air Service Retention and Expansion Committee - Plan

Senate File 2355 Sec. 19 (Iowa Code §328.13) created a commercial air service retention and expansion committee within the aviation office of the department of transportation. The membership of the committee consisted of the director or the director’s designee; the managers of each airport in Iowa with commercial air service; two members of the senate, one appointed by the majority leader of the senate and one appointed by the minority leader of the senate; and two members of the house of representatives, one appointed by the speaker of the house and one appointed by the minority leader of the house. The committee was to develop a plan by December 31, 2014 for the retention and expansion of passenger air service in Iowa. The committee is to meet as the committee deems necessary to assess progress in implementing the plan and, if necessary, to update the plan.

Congenital joint dislocations caused by carbohydrate sulfotransferase 3 deficiency in recessive Larsen syndrome and humero-spinal dysostosis

Deficiency of carbohydrate sulfotransferase 3 (CHST3; also known as chondroitin-6-sulfotransferase) has been reported in a single kindred so far and in association with a phenotype of severe chondrodysplasia with progressive spinal involvement. We report eight CHST3 mutations in six unrelated individuals who presented at birth with congenital joint dislocations. These patients had been given a diagnosis of either Larsen syndrome (three individuals) or humero-spinal dysostosis (three individuals), and their clinical features included congenital dislocation of the knees, elbow joint dysplasia with subluxation and limited extension, hip dysplasia or dislocation, clubfoot, short stature, and kyphoscoliosis developing in late childhood. Analysis of chondroitin sulfate proteoglycans in dermal fibroblasts showed markedly decreased 6-O-sulfation but enhanced 4-O-sulfation, confirming functional impairment of CHST3 and distinguishing them from diastrophic dysplasia sulphate transporter (DTDST)-deficient cells. These observations provide a molecular basis for recessive Larsen syndrome and indicate that recessive Larsen syndrome, humero-spinal dysostosis, and spondyloepiphyseal dysplasia Omani type form a phenotypic spectrum.

Official Positions for FRAX® clinical regarding biochemical markers from Joint Official Positions Development Conference of the International Society for Clinical Densitometry and International Osteoporosis Foundation on FRAX®.

The best indirect evidence that increased bone turnover contributes to fracture risk is the fact that most of the proven therapies for osteoporosis are inhibitors of bone turnover. The evidence base that we can use biochemical markers of bone turnover in the assessment of fracture risk is somewhat less convincing. This relates to natural variability in the markers, problems with the assays, disparity in the statistical analyses of relevant studies and the independence of their contribution to fracture risk. More research is clearly required to address these deficiencies before biochemical markers might contribute a useful independent risk factor for inclusion in FRAX(®).

Infant Mortality in Iowa Interim Study Committee, January 1992

The Infant Mortality in Iowa Interim Study Committee was established by the Legislative Council to review historical trends in Iowa's infant mortality rates to identify the extent of the problem on a statewide basis. Identify areas in the state with the greatest incidence of infant mortality, and research health complications. Identify factors which lead to impoverished families, and research access to health care services. Survey and review the current structure of service provided to pregnant women in Iowa health care facilities, and solicit information on the level of existing prenatal services. Recommend changes in Iowa's health care system which would lower Iowa's infant mortality rate.

Official Positions for FRAX® clinical regarding falls and frailty: can falls and frailty be used in FRAX®? From Joint Official Positions Development Conference of the International Society for Clinical Densitometry and International Osteoporosis Foundation on FRAX®.

Risk factors for fracture can be purely skeletal, e.g., bone mass, microarchitecture or geometry, or a combination of bone and falls risk related factors such as age and functional status. The remit of this Task Force was to review the evidence and consider if falls should be incorporated into the FRAX® model or, alternatively, to provide guidance to assist clinicians in clinical decision-making for patients with a falls history. It is clear that falls are a risk factor for fracture. Fracture probability may be underestimated by FRAX® in individuals with a history of frequent falls. The substantial evidence that various interventions are effective in reducing falls risk was reviewed. Targeting falls risk reduction strategies towards frail older people at high risk for indoor falls is appropriate. This Task Force believes that further fracture reduction requires measures to reduce falls risk in addition to bone directed therapy. Clinicians should recognize that patients with frequent falls are at higher fracture risk than currently estimated by FRAX® and include this in decision-making. However, quantitative adjustment of the FRAX® estimated risk based on falls history is not currently possible. In the long term, incorporation of falls as a risk factor in the FRAX® model would be ideal.

Transverse Joint Sealing with Various Sealants, HR-203, 1983

Iowa's first portland cement concrete pavement was constructed in 1904 in the City of LeMars. A portion of that pavement served traffic until 1974 at which time it was resurfaced. The first rural Iowa pee pavement (16' wide, 6" to 7" thick) was constructed under the direction of the Iowa State Highway Commission in 1913. Some of Iowa's early pavements had transverse joints at 25-foot spacings. At that time, joint spacings across the nation ranged from 24 to 100 ft. There have been many changes in joint design over the years with some pavements being constructed without transverse joints. Joint spacing on Iowa primary pavements has generally remained around 20 feet with this spacing having been adopted as an Iowa standard in 1954. Until 1978 it was common to specify a 40-foot joint spacing on secondary pavements. The performance of the pavements with joint spacings greater than 20 feet, and in some cases no contraction joints, generated a 1955 research project on joint spacing. This project was 16 miles long containing sections without contraction joints and sections with joints sawed at intervals of 20, 50 and 80 feet. Approximately half of the sawed joints were left unsealed. The results of this research supported the 20-foot spacing, but were inconclusive regarding the benefits of sealing. One of the desired characteristics of joint sealing material is that it should act as a moisture barrier and prevent the intrusion of surface water. It was generally accepted from past experience that the hot poured type joint seals did not provide this effective moisture barrier.

Transverse Joint Sealing with Improved Sealers, HR-276, 1991

Concern about premature joint sealant failures occurring in portland cement concrete (PCC) pavements gave impetus to initiating this research project. Eight sealants, including three silicone sealants, were evaluated and tested in the lab as well as incorporated in approximately 700 joints in the field and evaluated over a six-year period. The preliminary data show that among the silicone sealants, Dow Corning 888 rated the highest. However, this was rated third overall behind the W. R. Meadows cold-applied Sof Seal and Crafco #231 hot pour sealants. The W. R. Meadows and Crafco sealants cost approximately 30 percent and 50 percent less to furnish and place than the Dow Corning product. All joint sealants will continue to be evaluated.

Cardiac motion estimation by joint alignment of tagged MRI sequences

Image registration has been proposed as an automatic method for recovering cardiac displacement fields from Tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these techniques have evolved to the use of 3D+t deformation models, requiring metrics of joint image alignment (JA). However, only linear combinations of cost functions defined with respect to the first frame have been used. In this paper, we have applied k-Nearest Neighbors Graphs (kNNG) estimators of the -entropy (H ) to measure the joint similarity between frames, and to combine the information provided by different cardiac views in an unified metric. Experiments performed on six subjects showed a significantly higher accuracy (p < 0.05) with respect to a standard pairwise alignment (PA) approach in terms of mean positional error and variance with respect to manually placed landmarks. The developed method was used to study strains in patients with myocardial infarction, showing a consistency between strain, infarction location, and coronary occlusion. This paper also presentsan interesting clinical application of graph-based metric estimators, showing their value for solving practical problems found in medical imaging.

Haemophilia registry of the medical committee of the Swiss Haemophilia Society. Update and annual survey 2009.

The Swiss Haemophilia Registry of the Medical Committee of the Swiss Haemophilia Society started in 1996 but was set as an internet-based, double password-protected facility in the year 2000. With the inclusion of patients' data from two new centres in 2009, we assume a coverage rate of about 90% of all patients with inherited bleeding disorders in our country. Data concerning the phenotype and genotype of the disorder, its severity, its therapy, the prevalence of inhibitors are readily available to the registered users, allowing quality control of haemophilia therapy at a national level, but also rapid care of the patient visiting the emergency room of another treatment centre. Basing on the available data, about two thirds of the WFH global survey can be answered; the mortality statistics shows that bleeding remains a cause of death in haemophiliacs, also in the 21th century. The Registry allows for comparisons with international datasets, especially with respect to treatment (prophylaxis vs. on-demand therapy), factor consumption and costs.

Pressure Relief and Other Joint Rehabilitation Techniques, HR-1042, 1987

A study of four major concrete pavement joint rehabilitation techniques has been conducted, including: pressure relief joints, full-depth repairs, partial-depth repairs and joint resealing. The products of this research include the following for each technique: a summary of published research, detailed documentation of the design and performance of the 36 projects, conclusions and recommendations of the state highway engineers panel, "Design and Construction Guidelines" and "Guide Specifications." The latter two products are prepared for use by state highway agencies. The results of this study are based upon a review of literature, extensive field surveys and analysis of 36 rehabilitation projects, and the experience of an expert panel of state highway engineers.

Longitudinal Joint Forming in PCC Pavements, MLR-00-05, Construction Report, 2003

In conventional construction practices, a longitudinal joint is sawed in a PCC (Portland Cement Concrete) pavement to control concrete shrinkage cracking between two lanes of traffic. Sawing a joint in hardened concrete is an expensive and time consuming operation. The longitudinal joint is not a working joint (in comparison to a transverse joint) as it is typically tied with a tie bar at 30 inch spacing. The open joint reservoir, left by the saw blade, typically is filled or sealed with a durable crack sealant to keep incompressibles and water from getting into the joint reservoir. An experimental joint forming knife has been developed. It is installed under the paving machine to form the longitudinal joint in the wet concrete as a part of the paving process. Through this research method, forming a very narrow longitudinal joint during the paving process, two conventional paving operations can be eliminated. Joint forming eliminates the need of the joint sawing operation in the hard concrete, and as the joint that is formed does not leave a wide-open reservoir, but only a hairline crack, it does not need the joint filling or sealing operation. Therefore, the two conventional longitudinal joint sawing and sealing operations are both being eliminated by this innovation. A laboratory scale prototype joint forming knife was built and tested, initially forming joints in small concrete beams. The results were positive so the method was proposed for field testing. Initial field tests were done in the construction season of 2001, limited to one paving contractor. A number of modifications were made to the knife throughout the field tests. About 3000 feet of longitudinal joint was formed in 2001. Additional testing was done in the 2002 construction season, working with the same contractor. About 150,000 feet of longitudinal joint was formed in 2002. Evaluations of the formed joints were done to determine longitudinal joint hairline crack development rate and appearance. Additional tests will be done in the next construction season to improve or perfect the longitudinal joint forming technique.

Preformed Phoenix Ethylene Propylene Diene Monomer (EPDM) Compression Joint Seals, MLR-93-02, 1999

There is an ongoing drive towards improvements and achieving success in effective and long term sealing of portland cement concrete pavement contraction joints. A variety of joint sealing products and procedures have been applied in Iowa in search of improvements in seal performance. Hot poured rubberized asphalt products were mainly used for sealing all joints in earlier years for highways. In the 1980s, silicone sealant products were becoming popular, especially for the major highways. As a high level of sealant performance was not achieved from silicones in Iowa conditions, other sealing products were tried. Preformed neoprene compression seals are being tried as a substitution for silicone sealants. Due to high costs of materials and installation with neoprene seals, the search for improvements through other joint sealing products and procedures continued. An agreement was made with Phoenix, North America, Inc., to provide and install preformed Ethylene Propylene Diene Monomer (EPDM) compression joint seals. The research site was a 600 ft (183 m) test section of northbound I-29 in Pottawattamie County, Iowa. Seal installation was done August 20, 1992. Seal performance has been good over the past seven years and the seals are still showing no significant signs of decreasing performance.
