2007 State of Iowa Juvenile Justice and Delinquency Prevention Act Formule Grand Update

This document is Iowa’s 2007 JJDP Act formula grant three year plan update. When specific items of this plan are unchanged from the previously submitted 2006 plan, we have reflected accordingly in the respective topic areas of this document. The bulk of this 2007 plan is an “update” of the program plan completed since submission of the original 2006 plan. The Division of Criminal and Juvenile Justice Planning (CJJP) wrote Iowa’s three year plan update. CJJP is the state agency responsible for administering the JJDP Act in Iowa. Federal officials refer to state administering agencies as the state planning agency (SPA). The Plan was developed and approved by Iowa’s Juvenile Justice Advisory Council. That Council assists with administration of the JJDP Act, and also provides guidance and direction to the SPA, the Governor and the legislature regarding juvenile justice issues in Iowa. Federal officials refer to such state level groups as state advisory groups (SAG’s).

Antagonistes de l'angiotensine II et cancer: un bilan rassurant [Angiotensin II receptor blockers (ARBs) and cancer: a reassuring balance].

The effects of drugs on new cancer and cancer-related death are a major concern. Recently, a meta-analysis raised the possibility that ARBs might have an adverse impact in this respect. This point of view was highly debated until the publication of two other meta-analyses which did not demonstrate any increased risk of new cancer occurrence as well as of cancer related-death with the use of ARBs in patients with hypertension, heart failure and/or nephropathy. This illustrates that the results of meta-analyses should be interpreted cautiously and critically in order to avoid biased conclusions. Overall the bulk of evidence today indicates that ARBs are not associated with an increased cancer risk.

Combined written and oral information prior to gastrointestinal endoscopy compared with oral information alone: a randomized trial.

BACKGROUND: Little is known about how to most effectively deliver relevant information to patients scheduled for endoscopy. METHODS: To assess the effects of combined written and oral information, compared with oral information alone on the quality of information before endoscopy and the level of anxiety. We designed a prospective study in two Swiss teaching hospitals which enrolled consecutive patients scheduled for endoscopy over a three-month period. Patients were randomized either to receiving, along with the appointment notice, an explanatory leaflet about the upcoming examination, or to oral information delivered by each patient's doctor. Evaluation of quality of information was rated on scales between 0 (none received) and 5 (excellent). The analysis of outcome variables was performed on the basis of intention to treat-analysis. Multivariate analysis of predictors of information scores was performed by linear regression analysis. RESULTS: Of 718 eligible patients 577 (80%) returned their questionnaire. Patients who received written leaflets (N = 278) rated the quality of information they received higher than those informed verbally (N = 299), for all 8 quality-of-information items. Differences were significant regarding information about the risks of the procedure (3.24 versus 2.26, p < 0.001), how to prepare for the procedure (3.56 versus 3.23, p = 0.036), what to expect after the procedure (2.99 versus 2.59, p < 0.001), and the 8 quality-of-information items (3.35 versus 3.02, p = 0.002). The two groups reported similar levels of anxiety before procedure (p = 0.66), pain during procedure (p = 0.20), tolerability throughout the procedure (p = 0.76), problems after the procedure (p = 0.22), and overall rating of the procedure between poor and excellent (p = 0.82). CONCLUSION: Written information led to more favourable assessments of the quality of information and had no impact on patient anxiety nor on the overall assessment of the endoscopy. Because structured and comprehensive written information is perceived as beneficial by patients, gastroenterologists should clearly explain to their patients the risks, benefits and alternatives of endoscopic procedures.

Molecular mechanisms of penicillin-induced killing and penicillin tolerance in Streptococcus gordonii

Abstract The main thesis topic relates to the 'molecular mechanisms of penicillin-induced bacterial death. Indeed, bacteria have developed two principal mechanisms to escape the killing effect of ß-lactam antibiotics: resistance and tolerance. Resistant bacteria are characterized by their ability to grow in the presence of drug concentrations higher than the one inhibiting the growth of susceptible members of the same species. Hence, resistant bacteria have an increased minimal inhibitory concentration (MIC) of the drug. Nevertheless, when exposed to antibiotic concentrations exceeding their new MIC, resistant bacteria remain sensitive to the antibiotic killing effect. In contrast, tolerant bacteria have an unchanged MIC. However, they have a considerably increased ability to survive drug-induced killing, even at concentrations exceeding their MIC by several orders of magnitude. In other words, in the presence of the antibiotic, tolerant bacteria become persister cells which stop growing but are not killed. In the present thesis, it is shown that the survival phenotype of a tolerant Streptococcus gordonii strain depends on two components belonging to sugar metabolism pathways. First, the transcription factor CcpA which mediates a global regulatory mechanism allowing bacteria to utilize the most efficient sugar source for their growth. We show that the inactivation of the ccpA gene leads to a partial loss of penicillin tolerance both in vitro and in a rat model of experimental endocarditis. Second, the Enzyme I of the phosphotransferase system which is involved in the uptake and phosphorylation of sugars. Here, we -show that a single nucleotide mutation in ptsI, the gene encoding the Enzyme I, is sufficient to confer a fully tolerant phenotype in S. gordonii both in vivo and in vivo. The mutation results in a radical proline to arginine substitution in the C-terminal domain of the protein, probably leading to a decrease in its homodimerization and subsequent activity. Taken together our results prove that tolerance is a global survival mechanism linked to sugar metabolism. We hypothesize that, in the presence of the antibiotic, the already altered metabolic processes of the tolerant strain are completely inactivated. Hence, bacteria may enter in a dormant state and become insensitive to the bactericidal effect of ß-lactams, which depends on actively dividing cells. This thesis manuscript also contains two other side-projects. The first one establishes that the ability to form a biofilm is not a requisite for the successful establishment of endocarditis due to S. gordonii. The second one characterizes the S. gordonii a-phosphoglucomutase gene, and shows that its inactivation results in a loss of in vitro fitness and in vivo virulence. Résumé Le sujet principal de cette thèse concerne les mécanismes moléculaires de la mort bactérienne induite par la pénicilline. En effet, les bactéries ont développé deux mécanismes principaux pour échapper à l'effet bactéricide des ß-lactamines : la résistance et la tolérance. Les bactéries résistantes sont caractérisées par leur capacité de croître en présence de concentration d'antibiotiques plus élevées que celles inhibant la croissance des organismes sensibles de la même espèce. Les bactéries résistantes ont donc une augmentation de leur concentration minimale inhibitrice (CMI) à l'antibiotique. Néanmoins, quand elles sont exposées à des concentrations dépassant leur nouvelle CMI, elles restent sensibles à l'effet bactéricide. Au contraire, les bactéries tolérantes ont une CMI inchangée. Toutefois, elles ont une très importante capacité à survivre à l'effet bactéricide des ß-lactamines, ceci même à des concentrations excédant leur CMI de plusieurs ordres de grandeur. En d'autres termes, en présence de l'antibiotique, les bactéries tolérantes deviennent des cellules persistantes qui arrêtent leur croissance mais ne sont pas tuées. Dans la présente thèse, il est montré que le phénotype de survie d'un Streptococcus gordonii tolérant dépend de deux composants appartenant aux voies du métabolisme des sucres. Premièrement, le facteur de transcription CcpA qui contrôle un système global de régulation permettant à la bactérie d'utiliser les sources de sucre les plus efficaces pour sa croissance. Il est montré que l'inactivation du gène ccpA résulte en la perte partielle de la tolérance à la pénicilline aussi bien in vitro que dans un modèle d'endocardite expérimentale chez le rat. Deuxièmement, l'Enzyme I du système de phosphotransfert impliqué dans l'import et la phosphorylation des sucres. Nous montrons qu'une mutation ponctuelle d'un nucléotide dans ptsl, le gène codant pour l'Enzyme I, suffit à complètement conférer un phénotype tolérant chez S. gordonii aussi bien in vitro qu'in vivo. La mutation induit la substitution radicale d'une proline en une arginine dans le domaine C-terminal de la protéine, résultant probablement en une diminution de sa capacité d'homodimérisation et donc d'activité. Dans leur ensemble, nos résultats prouvent que la tolérance est un mécanisme global de survie lié au métabolisme des sucres. Nous présentons l'hypothèse que, en présence de l'antibiotique, les processus métaboliques déjà altérés de la souche tolérante deviennent complètement inactifs. En conséquence, les bactéries entreraient dans un état dormant nonréplicatif, devenant ainsi insensibles à l'effet bactéricide des ß-lactamines qui nécessite des cellules en cours de division active. Le manuscrit de cette thèse contient également deux projets secondaires. Le premier montre que la capacité de former un biofilm n'est pas un prérequis pour le succès de l'initiation de l'endocardite à S. gordonii. Le second caractérise le gène de l'a-phosphoglucomutase de S. gordonii et montre que son inactivation résulte en une perte de fitness in vitro et de virulence in vivo.

Implementation of raltegravir in routine clinical practice: selection criteria for choosing this drug, virologic response rates, and characteristics of failures.

BACKGROUND: Raltegravir (RAL) achieved remarkable virologic suppression rates in randomized-clinical trials, but today efficacy data and factors for treatment failures in a routine clinical care setting are limited. METHODS: First, factors associated with a switch to RAL were identified with a logistic regression including patients from the Swiss HIV Cohort Study with a history of 3 class failure (n = 423). Second, predictors for virologic outcome were identified in an intent-to-treat analysis including all patients who received RAL. Last observation carried forward imputation was used to determine week 24 response rate (HIV-1 RNA >or= 50 copies/mL). RESULTS: The predominant factor associated with a switch to RAL in patients with suppressed baseline RNA was a regimen containing enfuvirtide [odds ratio 41.9 (95% confidence interval: 11.6-151.6)]. Efficacy analysis showed an overall response rate of 80.9% (152/188), whereas 71.8% (84/117) and 95.8% (68/71) showed viral suppression when stratified for detectable and undetectable RNA at baseline, respectively. Overall CD4 cell counts increased significantly by 42 cells/microL (P < 0.001). Characteristics of failures were a genotypic sensitivity score of the background regimen <or=1, very low RAL plasma concentrations, poor adherence, and high viral load at baseline. CONCLUSIONS: Virologic suppression rates in our routine clinical care setting were promising and comparable with data from previously published randomized-controlled trials.

Molecular genetics and treatment of narcolepsy.

Narcolepsy is a neurological disorder characterized by excessive daytime sleepiness and cataplexy. The hypocretin/orexin deficiency is likely to be the key to its pathophysiology in most of cases although the cause of human narcolepsy remains elusive. Acting on a specific genetic background, an autoimmune process targeting hypocretin neurons in response to yet unknown environmental factors is the most probable hypothesis in most cases of human narcolepsy with cataplexy. Although narcolepsy presents one of the tightest associations with a specific human leukocyte antigen (HLA) (DQB1*0602), there is strong evidence that non-HLA genes also confer susceptibility. In addition to a point mutation in the prepro-hypocretin gene discovered in an atypical case, a few polymorphisms in monoaminergic and immune-related genes have been reported associated with narcolepsy. The treatment of narcolepsy has evolved significantly over the last few years. Available treatments include stimulants for hypersomnia with the quite recent widespread use of modafinil, antidepressants for cataplexy, and gamma-hydroxybutyrate for both symptoms. Recent pilot open trials with intravenous immunoglobulins appear an effective treatment of cataplexy if applied at early stages of narcolepsy. Finally, the discovery of hypocretin deficiency might open up new treatment perspectives.

Guidelines for the use and interpretation of assays for monitoring autophagy in higher eukaryotes.

Research in autophagy continues to accelerate,(1) and as a result many new scientists are entering the field. Accordingly, it is important to establish a standard set of criteria for monitoring macroautophagy in different organisms. Recent reviews have described the range of assays that have been used for this purpose.(2,3) There are many useful and convenient methods that can be used to monitor macroautophagy in yeast, but relatively few in other model systems, and there is much confusion regarding acceptable methods to measure macroautophagy in higher eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers of autophagosomes versus those that measure flux through the autophagy pathway; thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from fully functional autophagy that includes delivery to, and degradation within, lysosomes (in most higher eukaryotes) or the vacuole (in plants and fungi). Here, we present a set of guidelines for the selection and interpretation of the methods that can be used by investigators who are attempting to examine macroautophagy and related processes, as well as by reviewers who need to provide realistic and reasonable critiques of papers that investigate these processes. This set of guidelines is not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to verify an autophagic response.

Iowa Sex Offender Treatment and Supervision Task Force Report to the Iowa General Assembly, January 15, 2007

Over the last several years, lawmakers have been responding to several highly publicized child abduction, assault and murder cases. While such cases remain rare in Iowa, the public debates they have generated are having far-reaching effects. Policy makers are responsible for controlling the nature of such effects. Challenges they face stem from the need to avoid primarily politically-motivated responses and the desire to make informed decisions that recognize both the strengths and the limitations of the criminal justice system as a vehicle for promoting safe and healthy families and communities. Consensus was reached by the Task Force at its first meeting that one of its standing goals is to provide nonpartisan guidance to help avoid or fix problematic sex offense policies and practices. Setting this goal was a response to the concern over what can result from elected officials’ efforts to respond to the types of sex offender-related concerns that can easily become emotionally laden and politically charged due to the universally held abhorrence of sex crimes against children. The meetings of the Task Force and the various work groups it has formed have included some spirited and perhaps emotionally charged discussions, despite the above-stated ground rule. However, as is described in the report, the Task Force’s first set of recommendations and plans for further study were approved through consensus. It is hoped that in upcoming legislative deliberations, it will be remembered that the non-legislative members of the Task Force all agreed on the recommendations contained in this report. The topics discussed in this first report from the Task Force are limited to the study issues specifically named in H.F. 619, the Task Force’s enabling legislation. However, other topics of concern were discussed by the Task Force because of their immediacy or because of their possible relationships with one or more of the Task Force’s mandated study issues. For example, it has been reported by some probation/parole officers and others that the 2000 feet rule has had a negative influence on treatment participation and supervision compliance. While such concerns were noted, the Task Force did not take it upon itself to investigate them at this time and thus broaden the agenda it was given by the General Assembly last session. As a result, the recently reinstated 2000 feet rule, the new cohabitation/child endangerment law and other issues of interest to Task Force members but not within the scope of their charge are not discussed in the body of this report. An issue of perhaps the greatest interest to most Task Force members that was not a part of their charge was a belief in the benefit of viewing Iowa’s efforts to protect children from sex crimes with as comprehensive a platform as possible. It has been suggested that much more can be done to prevent child-victim sex crimes than would be accomplished by only concentrating on what to do with offenders after a crime has occurred. To prevent child victimization, H.F. 619 policy provisions rely largely on incapacitation and future deterrent effects of increased penalties, more restrictive supervision practices and greater public awareness of the risk presented by a segment of Iowa’s known sex offenders. For some offenders, these policies will no doubt prevent future sex crimes against children, and the Task Force has begun long-term studies to look for the desired results and for ways to improve such results through better supervision tools and more effective offender treatment. Unfortunately, much of the effects from the new policies may primarily influence persons who have already committed sex offenses against minors and who have already been caught doing so. Task Force members discussed the need for a range of preventive efforts and a need to think about sex crimes against children from other than just a “reaction- to-the-offender” perspective. While this topic is not addressed in the report that follows, it was suggested that some of the Task Force’s discussions could be briefly shared through these opening comments. Along with incapacitation and deterrence, comprehensive approaches to the prevention of child-victim sex crimes would also involve making sure parents have the tools they need to detect signs of adults with sex behavior problems, to help teach their children about warning signs and to find the support they need for healthy parenting. School, faithbased and other community organizations might benefit from stronger supports and better tools they can use to more effectively promote positive youth development and the learning of respect for others, respect for boundaries and healthy relationships. All of us who have children, or who live in communities where there are children, need to understand the limitations of our justice system and the importance of our own ability to play a role in preventing sexual abuse and protecting children from sex offenders, which are often the child’s own family members. Over 1,000 incidences of child sexual abuse are confirmed or founded each year in Iowa, and most such acts take place in the child’s home or the residence of the caretaker of the child. Efforts to prevent child sexual abuse and to provide for early interventions with children and families at risk could be strategically examined and strengthened. The Sex Offender Treatment and Supervision Task Force was established to provide assistance to the General Assembly. It will respond to legislative direction for adjusting its future plans as laid out in this report. Its plans could be adjusted to broaden or narrow its scope or to assign different priority levels of effort to its current areas of study. Also, further Task Force considerations of the recommendations it has already submitted could be called for. In the meantime, it is hoped that the information and recommendations submitted through this report prove helpful.

Evidential relevance in scene to offender transfer cases: development and analysis of a likelihood ratio for offence level propositions

The present paper focuses on the analysis and discussion of a likelihood ratio (LR) development for propositions at a hierarchical level known in the context as 'offence level'. Existing literature on the topic has considered LR developments for so-called offender to scene transfer cases. These settings involve-in their simplest form-a single stain found on a crime scene, but with possible uncertainty about the degree to which that stain is relevant (i.e. that it has been left by the offender). Extensions to multiple stains or multiple offenders have also been reported. The purpose of this paper is to discuss a development of a LR for offence level propositions when case settings involve potential transfer in the opposite direction, i.e. victim/scene to offender transfer. This setting has previously not yet been considered. The rationale behind the proposed LR is illustrated through graphical probability models (i.e. Bayesian networks). The role of various uncertain parameters is investigated through sensitivity analyses as well as simulations.

This article steps through the process using a sample data set of abstracts from the INSPEC database on the topic o "knowledge discovery and data mining." The paper offers a set of specific indicators suitable for mining such databases to understand innovation prospects. In illustrating the uses of such indicators, it offers some insights into the status of knowledge discovery research*.

Supporting interdisciplinary case studies: development and implementation of a joint learning environment for students in forensic science and criminal law

Scientific reporting and communication is a challenging topic for which traditional study programs do not offer structured learning activities on a regular basis. This paper reports on the development and implementation of a web application and associated learning activities that intend to raise the awareness of reporting and communication issues among students in forensic science and law. The project covers interdisciplinary case studies based on a library of written reports about forensic examinations. Special features of the web framework, in particular a report annotation tool, support the design of various individual and group learning activities that focus on the development of knowledge and competence in dealing with reporting and communication challenges in the students' future areas of professional activity.

P value and the theory of hypothesis testing: an explanation for new researchers.

In the 1920s, Ronald Fisher developed the theory behind the p value and Jerzy Neyman and Egon Pearson developed the theory of hypothesis testing. These distinct theories have provided researchers important quantitative tools to confirm or refute their hypotheses. The p value is the probability to obtain an effect equal to or more extreme than the one observed presuming the null hypothesis of no effect is true; it gives researchers a measure of the strength of evidence against the null hypothesis. As commonly used, investigators will select a threshold p value below which they will reject the null hypothesis. The theory of hypothesis testing allows researchers to reject a null hypothesis in favor of an alternative hypothesis of some effect. As commonly used, investigators choose Type I error (rejecting the null hypothesis when it is true) and Type II error (accepting the null hypothesis when it is false) levels and determine some critical region. If the test statistic falls into that critical region, the null hypothesis is rejected in favor of the alternative hypothesis. Despite similarities between the two, the p value and the theory of hypothesis testing are different theories that often are misunderstood and confused, leading researchers to improper conclusions. Perhaps the most common misconception is to consider the p value as the probability that the null hypothesis is true rather than the probability of obtaining the difference observed, or one that is more extreme, considering the null is true. Another concern is the risk that an important proportion of statistically significant results are falsely significant. Researchers should have a minimum understanding of these two theories so that they are better able to plan, conduct, interpret, and report scientific experiments.
