PROTEOMICS OF OXIDATIVE LESIONS OCCURRING DURING TRANSFUSION-PURPOSED STORAGE OF ERYTHROCYTE CONCENTRATES

Erythrocyte concentrates (ECs) are the major labile blood product being transfused worldwide, aiming at curing anemia of diverse origins. In Switzerland, ECs are stored at 4 °C up to 42 days in saline-adenine-glucose-mannitol (SAGM). Such storage induces cellular lesions, altering red blood cells (RBCs) metabolism, protein content and rheological properties. A hot debate exists regarding the impact of the storage lesions, thus the age of ECs on transfusion-related clinical adverse outcomes. Several studies tend to show that poorer outcomes occur in patients receiving older blood products. However, no clear association was demonstrated up to date. While metabolism and early rheological changes are reversible through transfusion of the blood units, oxidized proteins cannot be repaired, and it is likely such irreversible damages would affect the quality of the blood product and the efficiency of the transfusion. In vivo, RBCs are constantly exposed to oxygen fluxes, and are thus well equipped to deal with oxidative challenges. Moreover, functional 20S proteasome complexes allow for recognition and proteolysis of fairly oxidized protein, and some proteins can be eliminated from RBCs by the release of microvesicles. The present PhD thesis is involved in a global research project which goal is to characterize the effect of processing and storage on the quality of ECs. Assessing protein oxidative damages during RBC storage is of major importance to understand the mechanisms of aging of stored RBCs. To this purpose, redox proteomic-based investigations were conducted here. In a first part, cysteine oxidation and protein carbonylation were addressed via 2D-DIGE and derivatization-driven immunodetection approaches, respectively. Then, the oxidized sub- proteomes were characterized through LC-MS/MS identification of proteins in spots of interest (cysteine oxidation) or affinity-purified carbonylated proteins. Gene ontology annotation allowed classifying targets of oxidation according to their molecular functions. In a third part, the P20S activity was evaluated throughout the storage period of ECs, and its susceptibility to highly oxidized environment was investigated. The potential defensive role of microvesiculation was also addressed through the quantification of eliminated carbonylated proteins. We highlighted distinct protein groups differentially affected by cysteine oxidation, either reversibly or irreversibly. In addition, soluble extracts showed a decrease in carbonylation at the beginning of the storage and membrane extracts revealed increasing carbonylation after 4 weeks of storage. Engaged molecular functions revealed that antioxidant (AO) are rather reversibly oxidized at their cysteine residue(s), but are irreversibly oxidized through carbonylation. In the meantime, the 20S proteasome activity is decreased by around 40 % at the end of the storage period. Incubation of fresh RBCs extracts with exogenous oxidized proteins showed a dose-dependent and protein-dependent inhibitory effect. Finally, we proved that the release of microvesicles allows the elimination of increasing quantities of carbonylated proteins. Taken together, these results revealed an oxidative pathway model of RBCs storage, on which further investigation towards improved storage conditions will be based. -- Les concentrés érythrocytaires (CE) sont le produit sanguin le plus délivré au monde, permettant de traiter différentes formes d'anémies. En Suisse, les CE sont stocké à 4 °C pendant 42 jours dans une solution saline d'adénine, glucose et mannitol (SAGM). Une telle conservation induit des lésions de stockage qui altèrent le métabolisme, les protéines et les propriétés rhéologique du globule rouge (GR). Un débat important concerne l'impact du temps de stockage des CE sur les risques de réaction transfusionnelles, certaines études tentant de démontrer que des transfusions de sang vieux réduiraient l'espérance de vie des patients. Cependant, aucune association concrète n'a été prouvée à ce jour. Alors que les modifications du métabolisme et changement précoces des propriétés rhéologiques sont réversibles suite à la transfusion du CE, les protéines oxydées ne peuvent être réparées, et il est probable que de telles lésions affectent la qualité et l'efficacité des produits sanguins. In vivo, les GR sont constamment exposés à l'oxygène, et sont donc bien équipés pour résister aux lésions oxydatives. De plus, les complexes fonctionnels de proteasome 20S reconnaissent et dégradent les protéines modérément oxydées, et certaines protéines peuvent être éliminées par les microparticules. Cette thèse de doctorat est imbriquée dans un projet de recherche global ayant pour objectif la caractérisation des effets de la préparation et du stockage sur la qualité des GR. Evaluer les dommages oxydatifs du GR pendant le stockage est primordial pour comprendre les mécanismes de vieillissement des produits sanguin. Dans ce but, des recherches orientées redoxomique ont été conduites. Dans une première partie, l'oxydation des cystéines et la carbonylation des protéines sont évaluées par électrophorèse bidimensionnelle différentielle et par immunodétection de protéines dérivatisées. Ensuite, les protéines d'intérêt ainsi que les protéines carbonylées, purifiées par affinité, sont identifiées par spectrométrie de masse en tandem. Les protéines cibles de l'oxydation sont classées selon leur fonction moléculaire. Dans une troisième partie, l'activité protéolytique du protéasome 20S est suivie durant la période de stockage. L'impact du stress oxydant sur cette activité a été évalué en utilisant des protéines exogènes oxydées in vitro. Le potentiel rôle défensif de la microvesiculation a également été étudié par la quantification des protéines carbonylées éliminées. Dans ce travail, nous avons observé que différents groupes de protéines sont affectés par l'oxydation réversible ou irréversible de leurs cystéines. De plus, une diminution de la carbonylation en début de stockage dans les extraits solubles et une augmentation de la carbonylation après 4 semaines dans les extraits membranaires ont été montrées. Les fonctions moléculaires engagées par les protéines altérées montrent que les défenses antioxydantes sont oxydées de façon réversible sur leurs résidus cystéines, mais sont également irréversiblement carbonylées. Pendant ce temps, l'activité protéolytique du protéasome 20S décroit de 40 % en fin de stockage. L'incubation d'extraits de GR en début de stockage avec des protéines oxydées exogènes montre un effet inhibiteur « dose-dépendant » et « protéine-dépendant ». Enfin, les microvésicules s'avèrent éliminer des quantités croissantes de protéines carbonylées. La synthèse de ces résultats permet de modéliser une voie oxydative du stockage des GRs, à partir de laquelle de futures recherches seront menées avec pour but l'amélioration des conditions de stockage.

On-shoe wearable sensors for gait and turning assessment of patients with Parkinson's disease.

Assessment of locomotion through simple tests such as timed up and go (TUG) or walking trials can provide valuable information for the evaluation of treatment and the early diagnosis of people with Parkinson's disease (PD). Common methods used in clinics are either based on complex motion laboratory settings or simple timing outcomes using stop watches. The goal of this paper is to present an innovative technology based on wearable sensors on-shoe and processing algorithm, which provides outcome measures characterizing PD motor symptoms during TUG and gait tests. Our results on ten PD patients and ten age-matched elderly subjects indicate an accuracy ± precision of 2.8 ± 2.4 cm/s and 1.3 ± 3.0 cm for stride velocity and stride length estimation compared to optical motion capture, with the advantage of being practical to use in home or clinics without any discomfort for the subject. In addition, the use of novel spatio-temporal parameters, including turning, swing width, path length, and their intercycle variability, was also validated and showed interesting tendencies for discriminating patients in ON and OFF states and control subjects.

Coronary artery imaging by magnetic resonance.

Non-invasive visualization of the coronary arteries represents a major challenge in modern cardiology, but this goal may be achieved in the near future by MR angiography. Possible applications are non-invasive diagnosis of coronary artery disease, and follow-up examinations for therapy control after PTCA, in order to detect restenosis at an early stage. A multiple slice technique (2 mm slice thickness, with a spatial resolution of 1 x 1 mm, Philips Gyroscan ACS-II, 1.5 Tesla) was used. Ten volunteers were imaged and 10 patients with coronary artery disease were examined before and after PTCA. MR measurements were validated by quantitative coronary angiography. The diameters of the proximal coronary arteries as measured by both methods were compared, and a good correlation was found (r = 0.76). Thus, it is concluded that non-invasive visualization of the coronary arteries is possible before and after PTCA and allows to determine potential restenoses. However, patient cooperation is essential for good image quality. Moreover, limited spatial image resolution and breathing artifacts restrict MR coronary angiography today to be used as a routine diagnostic tool for the diagnosis of coronary artery disease.

Endoleak and in-stent thrombus detection with CT angiography in a thoracic aortic aneurysm phantom at different tube energies using filtered back projection and iterative algorithms.

PURPOSE: To determine the lower limit of dose reduction with hybrid and fully iterative reconstruction algorithms in detection of endoleaks and in-stent thrombus of thoracic aorta with computed tomographic (CT) angiography by applying protocols with different tube energies and automated tube current modulation. MATERIALS AND METHODS: The calcification insert of an anthropomorphic cardiac phantom was replaced with an aortic aneurysm model containing a stent, simulated endoleaks, and an intraluminal thrombus. CT was performed at tube energies of 120, 100, and 80 kVp with incrementally increasing noise indexes (NIs) of 16, 25, 34, 43, 52, 61, and 70 and a 2.5-mm section thickness. NI directly controls radiation exposure; a higher NI allows for greater image noise and decreases radiation. Images were reconstructed with filtered back projection (FBP) and hybrid and fully iterative algorithms. Five radiologists independently analyzed lesion conspicuity to assess sensitivity and specificity. Mean attenuation (in Hounsfield units) and standard deviation were measured in the aorta to calculate signal-to-noise ratio (SNR). Attenuation and SNR of different protocols and algorithms were analyzed with analysis of variance or Welch test depending on data distribution. RESULTS: Both sensitivity and specificity were 100% for simulated lesions on images with 2.5-mm section thickness and an NI of 25 (3.45 mGy), 34 (1.83 mGy), or 43 (1.16 mGy) at 120 kVp; an NI of 34 (1.98 mGy), 43 (1.23 mGy), or 61 (0.61 mGy) at 100 kVp; and an NI of 43 (1.46 mGy) or 70 (0.54 mGy) at 80 kVp. SNR values showed similar results. With the fully iterative algorithm, mean attenuation of the aorta decreased significantly in reduced-dose protocols in comparison with control protocols at 100 kVp (311 HU at 16 NI vs 290 HU at 70 NI, P ≤ .0011) and 80 kVp (400 HU at 16 NI vs 369 HU at 70 NI, P ≤ .0007). CONCLUSION: Endoleaks and in-stent thrombus of thoracic aorta were detectable to 1.46 mGy (80 kVp) with FBP, 1.23 mGy (100 kVp) with the hybrid algorithm, and 0.54 mGy (80 kVp) with the fully iterative algorithm.

Vaccination with a recombinant protein encoding the tumor-specific antigen NY-ESO-1 elicits an A2/157-165-specific CTL repertoire structurally distinct and of reduced tumor reactivity than that elicited by spontaneous immune responses to NY-ESO-1-expressing Tumors.

In a recent vaccination trial assessing the immunogenicity of an NY-ESO-1 (ESO) recombinant protein administered with Montanide and CpG, we have obtained evidence that this vaccine induces specific cytolytic T lymphocytes (CTL) in half of the patients. Most vaccine-induced CTLs were directed against epitopes located in the central part of the protein, between amino acids 81 and 110. This immunodominant region, however, is distinct from another ESO CTL region, 157-165, that is a frequent target of spontaneous CTL responses in A2+ patients bearing ESO tumors. In this study, we have investigated the CTL responses to ESO 157-165 in A2+ patients vaccinated with the recombinant protein. Our data indicate that after vaccination with the protein, CTL responses to ESO 157-165 are induced in some, but not all, A2+ patients. ESO 157-165-specific CTLs induced by vaccination with the ESO protein were functionally heterogeneous in terms of tumor recognition and often displayed decreased tumor reactivity as compared with ESO 157-165-specific CTLs isolated from patients with spontaneous immune responses to ESO. Remarkably, protein-induced CTLs used T-cell receptors similar to those previously isolated from patients vaccinated with synthetic ESO peptides (Vbeta4.1) and distinct from those used by highly tumor-reactive CTLs isolated from patients with spontaneous immune responses (Vbeta1.1, Vbeta8.1, and Vbeta13.1). Together, these results demonstrate that vaccination with the ESO protein elicits a repertoire of ESO 157-165-specific CTLs bearing T-cell receptors that are structurally distinct from those of CTLs found in spontaneous immune responses to the antigen and that are heterogeneous in terms of tumor reactivity, being often poorly tumor reactive.

Measurements of the bulk and interfacial velocity profiles in oscillating Newtonian and Maxwellian fluids

We present the dynamic velocity profiles of a Newtonian fluid (glycerol) and a viscoelastic Maxwell fluid (CPyCl-NaSal in water) driven by an oscillating pressure gradient in a vertical cylindrical pipe. The frequency range explored has been chosen to include the first three resonance peaks of the dynamic permeability of the viscoelastic-fluid¿pipe system. Three different optical measurement techniques have been employed. Laser Doppler anemometry has been used to measure the magnitude of the velocity at the center of the liquid column. Particle image velocimetry and optical deflectometry are used to determine the velocity profiles at the bulk of the liquid column and at the liquid-air interface respectively. The velocity measurements in the bulk are in good agreement with the theoretical predictions of a linear theory. The results, however, show dramatic differences in the dynamic behavior of Newtonian and viscoelastic fluids, and demonstrate the importance of resonance phenomena in viscoelastic fluid flows, biofluids in particular, in confined geometries.

Eight years experience from a skeletal dysplasia referral center in a tertiary hospital in Southern India: A model for the diagnosis and treatment of rare diseases in a developing country.

We report on a series of 514 consecutive diagnoses of skeletal dysplasia made over an 8-year period at a tertiary hospital in Kerala, India. The most common diagnostic groups were dysostosis multiplex group (n = 73) followed by FGFR3 (n = 49) and osteogenesis imperfecta and decreased bone density group (n = 41). Molecular confirmation was obtained in 109 cases. Clinical and radiographic evaluation was obtained in close diagnostic collaboration with expert groups abroad through Internet communication for difficult cases. This has allowed for targeted biochemical and molecular studies leading to the correct identification of rare or novel conditions, which has not only helped affected families by allowing for improved genetic counseling and prenatal diagnosis but also resulted in several scientific contributions. We conclude that (1) the spectrum of genetic bone disease in Kerala, India, is similar to that of other parts of the world, but recessive entities may be more frequent because of widespread consanguinity; (2) prenatal detection of skeletal dysplasias remains relatively rare because of limited access to expert prenatal ultrasound facilities; (3) because of the low accessibility to molecular tests, precise clinical-radiographic phenotyping remains the mainstay of diagnosis and counseling and of gatekeeping to efficient laboratory testing; (4) good phenotyping allows, a significant contribution to the recognition and characterization of novel entities. We suggest that the tight collaboration between a local reference center with dedicated personnel and expert diagnostic networks may be a proficient model to bring current diagnostics to developing countries. © 2014 Wiley Periodicals, Inc.

A fast 3D approach for coronary MRA.

Two-dimensional (2D)-breath-hold coronary magnetic resonance angiography (MRA) has been shown to be a fast and reliable method to depict the proximal coronary arteries. Recent developments, however, allow for free-breathing navigator gated and navigator corrected three-dimensional (3D) coronary MRA. These 3D approaches have potential for improved signal-to-noise ratio (SNR) and allow for the acquisition of adjacent thin slices without the misregistration problems known from 2D approaches. Still, a major impediment of a 3D acquisition is the increased scan time. The purpose of this study was the implementation of a free-breathing navigator gated and corrected ultra-fast 3D coronary MRA technique, which allows for scan times of less than 5 minutes. Twelve healthy adult subjects were examined in the supine position using a navigator gated and corrected ECG triggered ultra-fast 3D interleaved gradient echo planar imaging sequence (TFE-EPI). A 3D slab, consisting of 20 slices with a reconstructed slice thickness of 1.5 mm, was acquired with free-breathing. The diastolic TFE-EPI acquisition block was preceded by a T2prep pre-pulse, a diaphragmatic navigator pulse, and a fat suppression pre-pulse. With a TR of 19 ms and an effective TE of 5.4 ms, the duration of the data acquisition window duration was 38 ms. The in-plane spatial resolution was 1.0-1.3 mm*1.5-1.9 mm. In all cases, the entire left main (LM) and extensive portions of the left anterior descending (LAD) and right coronary artery (RCA) could be visualized with an average scan time for the entire 3D-volume data set of 2:57 +/- 0:51 minutes. Average contiguous vessel length visualized was 53 +/- 11 mm (range: 42 to 75 mm) for the LAD and 84 +/- 14 mm (range: 62 to 112 mm) for the RCA. Contrast-to-noise between coronary blood and myocardium was 5.0 +/- 2.3 for the LM/LAD and 8.0 +/- 2.9 for the RCA, resulting in an excellent suppression of myocardium. We present a new approach for free-breathing 3D coronary MRA, which allows for scan times superior to corresponding 2D coronary MRA approaches, and which takes advantage of the enhanced SNR of 3D acquisitions and the post-processing benefits of thin adjacent slices. The robust image quality and the short average scanning time suggest that this approach may be useful for screening the major coronary arteries or identification of anomalous coronary arteries. J.

The major histocompatibility complex and perfumers' descriptions of human body odors

The MHC (major histocompatibility complex) is a group of genes that play a crucial role in immune recognition and in tolerance of tissue grafting. The MHC has also been found to influence body odors, body odor preferences, and mate choice in mice and humans. Here we test whether verbal descriptions of human body odors can be linked to the MHC. We asked 45 male students to live as odor neutral as possible for two consecutive days and to wear a T-shirt during the nights. The odors of these T-shirts were then described by five evaluators: two professional perfumers and three laymen. One of the perfumers was able to describe the T-shirt odors in such a way that some of the allelic specificity of the MHC was significantly revealed (after Bonferroni correction for multiple testing). This shows that, although difficult, some people are able to describe MHCcorrelated body odor components.

Purpura of the face and neck: an atypical clinical presentation revealing a hepatosplenic T cell lymphoma

BACKGROUND: Hepatosplenic T cell lymphoma (HSTL) is a rare but very aggressive peripheral T cell lymphoma whose initial silent clinical presentation unfortunately delays the diagnosis and worsens the prognosis of patient survival. Efforts should be aimed at early recognition and treatment. METHODS: We describe a case of a 62-year-old woman who presented at our clinic with a non-palpable purpuric eruption of the face. Investigations revealed thrombocytopenia with hepatosplenomegaly, which showed rapid progression together with accentuation of the purpura. Two months later, a bone marrow biopsy revealed the diagnosis of a HSTL. RESULTS: The patient received six cycles of CHOP chemotherapy (vincristine, cyclophosphamide, doxorubicin, methylprednisolone) followed by a well-tolerated autologous bone marrow graft. Normalization of the platelet count resulted in regression of the purpuric rash. CONCLUSION: To our knowledge, this is the first report of a facial thrombocytopenic purpura as the inaugural symptom of HSTL. It emphasizes the privileged position of the dermatologist for early recognition of potentially lethal HSTL.

Multi-Atlas based Segmentation of Head and Neck CT Images using Active Contour

This paper presents the segmentation of bilateral parotid glands in the Head and Neck (H&N) CT images using an active contour based atlas registration. We compare segmentation results from three atlas selection strategies: (i) selection of "single-most-similar" atlas for each image to be segmented, (ii) fusion of segmentation results from multiple atlases using STAPLE, and (iii) fusion of segmentation results using majority voting. Among these three approaches, fusion using majority voting provided the best results. Finally, we present a detailed evaluation on a dataset of eight images (provided as a part of H&N auto segmentation challenge conducted in conjunction with MICCAI-2010 conference) using majority voting strategy.

Defining and searching for structural motifs using DeepView/Swiss-PdbViewer.

BACKGROUND: Today, recognition and classification of sequence motifs and protein folds is a mature field, thanks to the availability of numerous comprehensive and easy to use software packages and web-based services. Recognition of structural motifs, by comparison, is less well developed and much less frequently used, possibly due to a lack of easily accessible and easy to use software. RESULTS: In this paper, we describe an extension of DeepView/Swiss-PdbViewer through which structural motifs may be defined and searched for in large protein structure databases, and we show that common structural motifs involved in stabilizing protein folds are present in evolutionarily and structurally unrelated proteins, also in deeply buried locations which are not obviously related to protein function. CONCLUSIONS: The possibility to define custom motifs and search for their occurrence in other proteins permits the identification of recurrent arrangements of residues that could have structural implications. The possibility to do so without having to maintain a complex software/hardware installation on site brings this technology to experts and non-experts alike.

The role of actions in auditory object discrimination.

Action representations can interact with object recognition processes. For example, so-called mirror neurons respond both when performing an action and when seeing or hearing such actions. Investigations of auditory object processing have largely focused on categorical discrimination, which begins within the initial 100 ms post-stimulus onset and subsequently engages distinct cortical networks. Whether action representations themselves contribute to auditory object recognition and the precise kinds of actions recruiting the auditory-visual mirror neuron system remain poorly understood. We applied electrical neuroimaging analyses to auditory evoked potentials (AEPs) in response to sounds of man-made objects that were further subdivided between sounds conveying a socio-functional context and typically cuing a responsive action by the listener (e.g. a ringing telephone) and those that are not linked to such a context and do not typically elicit responsive actions (e.g. notes on a piano). This distinction was validated psychophysically by a separate cohort of listeners. Beginning approximately 300 ms, responses to such context-related sounds significantly differed from context-free sounds both in the strength and topography of the electric field. This latency is >200 ms subsequent to general categorical discrimination. Additionally, such topographic differences indicate that sounds of different action sub-types engage distinct configurations of intracranial generators. Statistical analysis of source estimations identified differential activity within premotor and inferior (pre)frontal regions (Brodmann's areas (BA) 6, BA8, and BA45/46/47) in response to sounds of actions typically cuing a responsive action. We discuss our results in terms of a spatio-temporal model of auditory object processing and the interplay between semantic and action representations.

MDCT arthrography of the hip: value of the adaptive statistical iterative reconstruction technique and potential for radiation dose reduction.

OBJECTIVE: The purpose of this article is to assess the effect of the adaptive statistical iterative reconstruction (ASIR) technique on image quality in hip MDCT arthrography and to evaluate its potential for reducing radiation dose. SUBJECTS AND METHODS: Thirty-seven patients examined with hip MDCT arthrography were prospectively randomized into three different protocols: one with a regular dose (volume CT dose index [CTDIvol], 38.4 mGy) and two with a reduced dose (CTDIvol, 24.6 or 15.4 mGy). Images were reconstructed using filtered back projection (FBP) and four increasing percentages of ASIR (30%, 50%, 70%, and 90%). Image noise and contrast-to-noise ratio (CNR) were measured. Two musculoskeletal radiologists independently evaluated several anatomic structures and image quality parameters using a 4-point scale. They also jointly assessed acetabular labrum tears and articular cartilage lesions. RESULTS: With decreasing radiation dose level, image noise statistically significantly increased (p=0.0009) and CNR statistically significantly decreased (p=0.001). We also found a statistically significant reduction in noise (p=0.0001) and increase in CNR (p≤0.003) with increasing percentage of ASIR; in addition, we noted statistically significant increases in image quality scores for the labrum and cartilage, subchondral bone, overall diagnostic quality (up to 50% ASIR), and subjective noise (p≤0.04), and statistically significant reductions for the trabecular bone and muscles (p≤0.03). Regardless of the radiation dose level, there were no statistically significant differences in the detection and characterization of labral tears (n=24; p=1) and cartilage lesions (n=40; p≥0.89) depending on the ASIR percentage. CONCLUSION: The use of up to 50% ASIR in hip MDCT arthrography helps to reduce radiation dose by approximately 35-60%, while maintaining diagnostic image quality comparable to that of a regular-dose protocol using FBP.

Juvenile Crime Prevention Community Grand Fund Outcomes Report and FY2002 Juvenile Justice Youth Development Program Summary, January 2002

This document contains two related, but separate reports. The Juvenile Crime Prevention Community Grant Fund Outcomes Report is a summary of outcomes from services and activities funded through the Juvenile Crime Prevention Community Grant Fund in FY2001. The Juvenile Justice Youth Development Program Summary describes Iowa communities’ current prevention and sanction programs supported with funding from the Division of Criminal and Juvenile Justice Planning (CJJP) during FY2002. The material in Juvenile Crime Prevention Community Grant Fund Outcomes Report is presented in response to a legislative mandate to report specific prevention outcomes for the community Grant Fund. It includes a brief description of a Youth Development Results Framework established by the Iowa Collaboration for Youth Development. Outcomes are reported using this results framework, which was developed by a number of state agencies as a common tool for various state programs involving youth development related planning and funding processes. Included in this report is a description of outcomes from the prevention activities funded, all or in part, by the Community Grant Fund, as reported by local communities. The program summaries presented in the Juvenile Justice Youth Development Program Summary provide an overview of local efforts to implement their 2002 Juvenile Justice Youth Development plans and include prevention and sanction programs funded through the combined resources of the State Community Grant Fund and the Federal Title V Prevention, Juvenile Justice & Delinquency Prevention Act Formula Grant and Juvenile Accountability Incentive Block Grant programs. These combined funds are referred to in this document as the Juvenile Justice Youth Development (JJYD) funds. To administer the JJYD funds, including funds from the Community Grant Fund, CJJP partners with local officials to facilitate a community planning process that determines the communities’ priorities for the use of the funds. The local planning is coordinated by the Iowa’s Decategorization Boards (Decats). These local officials and/or their staff have been leaders in providing oversight or staff support to a variety of local planning initiatives (e.g. child welfare, Comprehensive Strategy Pilot Projects, Empowerment, other) and bring child welfare and community planning experience to the table for the creation of comprehensive community longterm planning efforts. The allocation of these combined funds and the technical assistance received by the Decats from CJJP is believed to have helped enhance both child welfare and juvenile justice efforts locally and has provided for the recognition and establishment of connections for joint child welfare/juvenile justice planning. The allocation and local planning approach has allowed funding from CJJP to be “blended” or “braided” with other local, state, and federal dollars that flow to communities as a result of their local planning responsibilities. The program descriptions provided in this document reflect services and activities supported with JJYD funds. In many cases, however, additional funding sources have been used to fully fund the programs. Most of the information in this document’s two reports was submitted to CJJP by the communities through an on- line planning and reporting process established jointly by the DHS and CJJP.
