Status of Females in the Juvenile Justice System Iowa, 2009

Young women in the juvenile justice system present with characteristics and experiences that differentiate them from their male counterparts. As such, the juvenile justice system in Iowa must consider these factors if it is to effectively and efficiently impact recidivism, rehabilitation and public safety. Data reveal the following trends: All youth in the juvenile justice system experience a significantly higher rate of child maltreatment than do youth in the general population. Additionally, young women have a distinctly higher percentage of reported sexual abuse. Young women commit primarily non-violent offenses, with shoplifting and running away being the only two areas where they exceed young men in number. Young women are held in detention for a substantially higher percentage of misdemeanor versus felony offenses than young men. Young women of color, particularly African American females, are far more likely to come into contact with the juvenile justice system. Additionally, arrests of minority females have increased during the same time frame as arrests of Caucasian females have decreased. The general type of offense committed by young women is against public order (i.e. alcohol related violations, disorderly conduct) or property (i.e. shoplifting), though young women with subsequent charges of a violent nature are likely to have had violent offenses initially as well. Historically, young women have been a smaller segment of the juvenile justice population. They remain so today. Consequently, they are easy to overlook. But Iowa’s response to them is no less important. Perhaps, because they are fewer in number, our system can have a true and meaningful influence, with prevention of further penetration into both the juvenile and adult systems being the ultimate goal. The Iowa Task Force on Young Women recommends the following measures to facilitate movement toward that goal: 1. Facilities and programs striving to provide the most effective and efficient services to young women will opt for single gender environments with female responsive programming that includes components to address trauma. 2. All institutions and agencies that work with females involved in the juvenile justice system and which receive state funding should be required to provide annual female responsive training to their employees. Training should be research based, progressive, ongoing and result in an implementation plan. 3. As detention reform proceeds, gender and the disproportionate number of females in detention for misdemeanor offenses must be an integral part of policy and decision making discussions including any recommendations for solutions to be implemented. 4. As research, data and planning progresses related to disproportionate minority contact with the juvenile system, the needs of girls of color be given equal consideration. Specifically, assessment tools must be without race/ethnic bias and they must also be female responsive.

Relationships between soil class and nutritional status of coffee plantations

Farm planning requires an assessment of the soil class. Research suggest that the Diagnosis and Recommendation Integrated System (DRIS) has the capacity to evaluate the nutritional status of coffee plantations, regardless of environmental conditions. Additionally, the use of DRIS could reduce the costs for farm planning. This study evaluated the relationship between the soil class and nutritional status of coffee plants (Coffea canephora Pierre) using the Critical Level (CL) and DRIS methods, based on two multivariate statistical methods (discriminant and multidimensional scaling analyses). During three consecutive years, yield and foliar concentration of nutrients (N, P, K, Ca, Mg, S, B, Zn, Mn, Fe and Cu) were obtained from coffee plantations cultivated in Espírito Santo state. Discriminant analysis showed that the soil class was an important factor determining the nutritional status of the coffee plants. The grouping separation by the CL method was not as effective as the DRIS one. The bidimensional analysis of Euclidean distances did not show the same relationship between plant nutritional status and soil class. Multidimensional scaling analysis by the CL method indicated that 93.3 % of the crops grouped into one cluster, whereas the DRIS method split the fields more evenly into three clusters. The DRIS method thus proved to be more consistent than the CL method for grouping coffee plantations by soil class.

Evaluation of the immune response to infection with metastatic and non-metastatic "Leishmania guyanensis" parasites

ABSTRACT : Les infections par le parasite Leishmania guyanensis se caractérisent par une dissémination depuis le site initial d'infection jusqu'aux tissus naso-pharyngés, responsable de la Leishmaniose à lésions secondaires muco-cutanées (LMC). Les lésions des patients atteints de LMC montrent une massive infiltration de cellules immunitaires, une réponse immunitaire élevée et la présence de parasites (bien qu'en très faible quantité). La LMC engendre une augmentation de l'expression de TNFa ainsi qu'un défaut dans le contrôle de la réponse immunitaire caractérisé par une absence de réponse à l'IL 10. La réponse immunitaire de l'hôte ainsi que la virulence du parasite sont deux facteurs reconnus pour le contrôle de l'infection. Le mécanisme de la pathogenèse de la LMC restent grandement incompris, surtout le mécanisme de dissémination de l'infection du site d'inoculation jusqu'aux sites secondaires d'infection (métastases) ainsi que les détails de la réponse de l'hôte contre le pathogène. Dans un modèle d'infection d' hamsters avec des parasites du Nouveau Monde, la classification des parasites Leishmania se fait en fonction de leur capacité à développer des métastases. Ce modéle d'infection a permis de caractériser différentes souches de parasites selon la classification de l'Organisation Mondiale de la Sante (OMS) tel que la souche de référence W>É-II/BR/78/M5313 qui est reconnue comme hautement métastatique alors que ces clones dérivés de M5313 montrent de grandes variations quand a leur capacité à créer des métastases. Les clones 13 et 21 sont métastatiques (M+) alors que les clones 3 et 17 sont nonmétastatiques (NI-). Les objectifs de cette thèse ont été d'étudier le rôle de la réponse immunitaire innée des macrophages après infection in vitro avec différents clones métastatiques et non-métastatiques du parasite L. guyanensis, ainsi que d'étudier la réponse immunitaire générée suite à une infection in vivo par les clones M+ et M- de L. guyanensis dans un modèle marin. L'analyse de la .réponse immunitaire des macrophages in vitro montrent qu'il y aune augmentation significative de leur statut d'activation après infection par des parasites M+ indiquée par la modulation des marqueurs d'activation de surface CD80, CD86 et CD40, ainsi que une augmentation significative de CXCL 10, CCLS, IL6 et TNFa au niveau transcription de l'ARNm et au niveau de la protéine. Cette phénomène d'activation a été observée chez les deux souches de souris C57BL/6 et BALB/c. L'utilisation d'un inhibiteur d'entrée des parasites (Cytochalsin D) ou d'un inhibiteur des fonctions endosomales (Chloroquine) diminue de manière significative la réponse des macrophages aux parasites M+. L'utilisation de macrophages déficients en TLR, MyD88, et TRIF a démontré que la réponse générée après infection par les parasites M+ était dépendante de la voie de signalisation de TRIF et TLR3. Lors d'infection in vivo par des parasites M5313, au moins 50% des souris BALB/c présentent un phénotype sensible caractérisé par des lésions non-nécrotiques qui ne guérissent pas, persistent plus de 13 semaines après infection et contiennent un nombre considérable de parasites. Ces souris développent une réponse immunitaire de type T helper 2 (Th2) avec un niveau élevé d'IL-4 et d'IL-10. Les autres souris ont un phénotype non-sensible, les souris développant peu ou pas de lésion, avec peu de parasites et une réponse immunitaire diminuée, caractérisée par un niveau faible d'IFNy, d'IL4 et d'IL10. De plus, les souris BALB/c infectées par un parasite L. guyanensis isolé à partir des lésions muco-cutanées d'un patient humain atteint de LMC ont démontrés un phénotype similaire aux souris infectées par la souche M5313 avec 50% des souris développant des lésions persistantes, alors qu'un parasite dérivé des lésions cutanées humains n'a montré qu'une faible sensibilité avec une lésion transitoire qui finit par guérir. Nous avons montré que la sensibilité de ces souris BALB/c dépend de l'IL-4 et de l'IL-10 car les souris IL-10-/sur fond génétique BALB/c ainsi que les souris BALB/c traitée avec de l'anti-IL4 étaient capables de contrôler l'infection par M5313. Les souris C57BL/6 sont résistantes à l'infection par le parasite M5313. Elles développent une lésion transitoire qui guérit 9 semaines après infection. Ces souris résistantes ont un très faible taux de parasites au site d'infection et développent une réponse immunitaire de type Thl avec un niveau élevé d'IFNr et peu d'IL4 et d'IL10. Les infections in vivo de souris déficientes en MyD88, TRIF, TLR3 ou TLR9 (sur fond génétique C57BL/6) ont indiqué que MyD88 et TLR9 étaient impliqués dans la résistance à l'infection par L. guyanensi, et que TRIF et TLR3 avaient un rôle important dans la sensibilité. Ce travail met en évidence le fait que la réponse immunitaire de l'hôte est modulée par le parasite selon leur caractérisation d'être soit M+ ou M-. Nous avons démontré également que plusieurs gènes et voies de signalisations étaient impliqués dans cette réponse favorisant le développement d'une LMC. ABSTRACT : Leishmania guyanensis parasites are able to disseminate from the initial site of cutaneous skin infection to the nasopharyngeal tissues resulting in destructive secondary lesions and the disease Mucocutaneous Leishmaniasis (MCL). The secondary lesions in patients have intense immune cell infiltration, elevated immune responses and the presence (albeit at low levels) of parasites. More specifically, MCL patients produce higher levels of TNFa and display impairment in their ability to control the immune response due to a defect in their ability to respond to IL10. Little is known about the pathogenesis of MCL, especially about the dissemination of the infection from the site of inoculation to secondary sites (metastasis) and the response of the host to the pathogen. The hamster model of L. guyanensis infection has previously characterized the WHO reference strain, L. guyanensis WHI/BR/78/M5313, as being highly metastatic. Clones of parasites derived from this reference strain show a differential ability to metastasize. This thesis studied the differential immune response generated by macrophages in vitro, or by mice in vivo, following infection with L. guyanensis parasites. A significant increase in the activation status of macrophages derived from C57BL/6 or BALB/c mice was observed after in vitro infection with L. guyanensis parasites when compared to non-metastatic parasites. This change in status was evidenced by the increased expression of surface activation markers, together with the chemokines, CXCL 10, CCLS, and cytokines, IL6 and TNFa. Furthermore, in vitro infection of macrophages isolated from mice deficient in either a specific Toll Like Receptor (TLR) or the adaptor molecules MyD88 or TRIF, indicated that the immune response generated following L. guyanensis metastatic parasite infection was reliant on the TRIF dependent TLR3 signalling pathway. In vivo footpad infection of BALB/c mice with the L. guyanensis M5313 parasites showed a reproducible susceptible phenotype, whereby at least 50% of infected mice developed non-healing, nonnecrosing lesions with high parasitemia that persisted over 13 weeks post infection. This phenotype was characterized by a Th2 type cytokine immune response with increased levels of IL4 and IL10 detected in the draining lymph nodes. IL 10 deficient mice on a BALB/c background, or BALB/c mice treated with anti-IL4 were able to control infection with L. guyanensis M5313 parasites, thereby proving that these cytokines were indeed implicated in the susceptibility to infection. Moreover, infection of BALB/c mice with patient isolated L. guyanensis parasites confirmed that MCL derived parasites were able to induce a susceptibility phenotype similar to that of L. guyanensis M5313. C57BL/6 mice, on the other hand, were highly resistant to infection with L. guyanensis M5313 parasites and produced transient footpad swelling that healed by week 9 post infection, together with low degrees of footpad parasitemia and a Thl polarized immune response. Infection of mice deficient in MyD88, TRIF, TLR3, and TLR9 (on a C57BL/6 background), indicated that MyD88 and TLR9 were involved in the resistance of these mice to infection, and that TRIF and TLR3 were involved in the susceptibility. This study has shown that the host response can be differentially modulated depending on the infecting parasite with several genes and pathways being identified that could be involved in promoting the development of MCL.

Construction and Quantitative Evaluation of a Dual Specific Promoter System for Monitoring the Expression Status of Stra8 and c-kit Genes.

Applications of genetic constructs with multiple promoters, which are fused with reporter genes and simultaneous monitoring of various events in cells, have gained special attention in recent years. Lentiviral vectors, with their distinctive characteristics, have been considered to monitor the developmental changes of cells in vitro. In this study, we constructed a novel lentiviral vector (FUM-M), containing two germ cell-specific promoters (Stra8 and c-kit), fused with ZsGreen and DsRed2 reporter genes, and evaluated its efficiency in different cells following treatments with retinoic acid and DMSO. Several cell lines (P19, GC-1 spg and HEK293T) were transduced with this vector, and functional capabilities of the promoters were verified by flow cytometry and quantitative RT-PCR. Our results indicate that FUM-M shows dynamic behavior in the presence and absence of extrinsic factors. A correlation was also observed between the function of promoters, present in the lentiviral construct and the endogenous level of the Stra8 and c-kit mRNAs in the cells. In conclusion, we recommend this strategy, which needs further optimization of the constructs, as a beneficial and practical way to screen chemical inducers involved in cellular differentiation toward germ-like cells.

The relationship between a short measure of health status and physical activity in a workplace population.

Many interventions promoting physical activity (PA) are effective in preventing disease onset, and although studies have found a positive relationship between health-related quality of life (HRQL) and PA, most of these studies have focused on older adults and those with chronic conditions. Less is known regarding the association between PA level and HRQL among healthy adults. Our objective was to analyse the relationship between PA level and HRQL among a sample of 573 employees aged 20-68 taking part in a workplace intervention to promote PA. Measures included HRQL (using a single item) and PA (i.e. Godin Leisure-Time Questionnaire). The Modified Canadian Aerobic Fitness Test (MCAFT) was also completed by 10% of the employees. MET-minute scores (assessing energy expenditure over one week) were compared across HRQL categories using ANOVA. A multiple linear regression analysis was conducted to further examine the relationship between HRQL and PA, controlling for potential covariates. Participants in the higher health status categories were found to report higher levels of energy expenditure (one-way ANOVA, p < 0.001). In the multiple linear regression model, each unit increase in health status level translated in a mean increase of 356 MET-minutes in energy expenditure (p < 0.001). This single-item assessment of health status explained six percent of the variance in energy expenditure. The study concludes that higher energy expenditure through PA among an adult workplace population is positively associated with increased health status, and it also suggests that a single-item HRQL measure is suitable for community- and population-based studies, reducing response burden and research costs.

Mechanisms of antifungal resistance in the opportunistic fungus Aspergillus fumigatus

ABSTRACT Aspergillus fumigatus is one of the most prevalent airbone fungal pathogen and can cause severe fatal invasive aspergillosis in immunocompromised patients. Several antifungal agents are available to treat these infections but with limited success. These agents include polyenes (amphotericin B), echinocandins (caspofungin) and azoles, which constitute the most important class with itraconazole (ITC) and voriconazole as major active compounds. Azole-derived antifungal agents target the ergosterol biosynthesis pathway via the inhibition of the lanosterol 14α-demethylase (cyp51/ERG1 1), a cytochrome P450 responsible for the conversion of lanosterol to ergosterol, which is the main component of cell membrane in fungi. A. fumigatus is also found in the environment as a contaminant of rotting plant or present in composting of organic waste. Among antifungal agents used in the environment for crop protection, the class of azoles is also widely used with propiconazole or prochloraz as examples. However, other agents such as dicarboximide (iprodione), phenylamide (benalaxyl) or strobilurin (azoxystrobin) are also used. Emergence of clinical azole-resistant isolates has been described in several European countries. However the incidence of antifungal resistance has not been yet reported in details in Switzerland. In this study, the status of antifungal resistance was investigated on A. fumigatus isolates collected from Swiss hospitals and from different environmental sites and. tested for their susceptibility to several currently used antifungal agents. The data showed a low incidence of resistance for all tested agents among clinical and environmental isolates. Only two azole-resistant environmental isolates were detected and none among the clinical tested isolates. In general, A. fumigatus was susceptible to all antifungals tested in our study, except to azoxystrobin which was the less active agent against all isolates. Since mechanisms of antifungal resistance have been poorly investigated until now in A. fumigatus, this work was aimed 1) to identify A. fumigatus genes involved in antifungal resistance and 2) to test their involvement in the development of resistance in sampled isolates. Therefore, this work proposed to isolate A. fumigatus genes conferring resistance to a drug-hypersusceptible Saccharomyces cerevisiae strain due to a lack of multidrug transporter genes. Several genes were recovered including three distinct efflux transporters (atrF, atrH and mdrA) and a bZip transcription factor, yapA. The inactivation of each transporter in A. fumigatus indicated that the transporters were involved in the basal level of azole susceptibility. The inactivation of YapA led to a hypersusceptibility to H2O2, thus confirming the involvement of this gene in the oxidative stress response of A. fumigatus. The involvement of the abovementioned transporters genes and of other transporters genes identified by genome analysis in azole resistance was tested by probing their expression in some ITC-resistant isolates. Even if upregulation of some transporters genes was observed in some investigated isolates, the correlation between azole resistance and expression levels of all these transporters genes could not be clearly established for all tested isolates. Given these results, the present work addressed 1) alteration in the expression of cyp51A encoding for the azole target enzyme, and 2) mutation(s) in the cyp51A sequence as potential mechanisms of azote resistance in A. . However, overexpression of cyp51A in the investigated isolates was not linked with azote resistance. Since it was reported that mutation(s) in cyp51A were participating in azote resistance in A. fumigatus, a functional complementation of cyp51A cDNAs from ITC-resistant A. fumigatus strains in S. cerevisiae ergl 1 Δ mutant strain was attempted. Expression in S. cerevisiae allowed the testing of these cDNAs with regards to their functionality and involvement in resistance to specific azote compounds. We could demonstrate that Cyp51A protein with a G54E or M220K mutations conferred resistance to specific azoles in S. cerevisiae, therefore suggesting that these mutations were important for the development of azote resistance in A. fumigatus. In conclusion, this work showed a correlation between ITC resistance and mechanisms involving overexpression of transporters and cyp51A mutations in A. fumigatus isolates. However, azole resistance of some isolates has not been solved and thus it will be necessary to approach the study of resistance mechanisms in this fungal species using alternative methodologies. RESUME Aspergillus fumigatus est un champignon opportuniste répandu et est la cause d'aspergilloses invasives le plus souvent fatales chez des patients immunodéprimés. Plusieurs antifongiques sont disponibles afin de traiter ces infections, cependant avec un succès limité. Ces agents incluent les polyènes (amphotericin B), les échinocandines (caspofungin) et les azoles, qui représentent la plus importante classe d'antifongiques avec l'itraconazole (ITC) et le voriconazole comme principaux agents actifs. Les dérivés azolés ciblent la voie de biosynthèse de l'ergostérol via l'inhibition de la lanostérol 14α-demethylase (cyp51/ERG11), un cytochrome P450 impliqué dans la conversion du lanostérol en ergostérol, qui est un composant important de la membrane chez les champignons. A. fumigatus est également répandu dans l'environnement. Parmi les antifongiques employés en agriculture afin de protéger les cultures, les azoles sont aussi largement utilisés. Cependant, d'autres agents tels que les dicarboximides (iprodione), les phenylamides (benalaxyl) et les strobilurines (azoxystrobin) peuvent être également utilisés. L'émergence de souches cliniques résistantes aux azoles a été décrite dans différents pays européens. Cependant, l'incidence d'une telle résistance aux azoles n'a pas encore été reportée en détails en Suisse. Dans ce travail, l'émergence de la résistance aux antifongiques a été étudiée par analyse de souches d'A. fumigatus provenant de milieux hospitaliers en Suisse et de différents sites et leur susceptibilité testée envers plusieurs antifongiques couramment utilisés. Les données obtenues ont montré une faible incidence de la résistance parmi les souches cliniques et environnementales pour les agents testés. Seulement deux souches environnementales résistantes aux azoles ont été détectées et aucune parmi les souches cliniques. Les mécanismes de résistance aux antifongiques ayant été très peu étudiés jusqu'à présent chez A. fumigatus , ce travail a eu aussi pour but 1) d'identifier les gènes d' A. fumigatus impliqués dans la résistance aux antifongiques et 2) de tester leur implication dans la résistance de certaines souches. Ainsi, il a été proposé d'isoler les gènes d' A. fumigatus pouvant conférer une résistance aux antifongiques à une souche de Saccharomyces cerevisiae hypersensible aux antifongiques. Trois transporteurs à efflux (atrF, atrH et mdrA) et un facteur de transcription appartenant à la famille des bZip (YapA) ont ainsi été isolés. L'inactivation, dans une souche d'A. fumigatus, de chacun des ces transporteurs a permis de mettre en évidence leur implication dans la susceptibilité d'A. fumigatus aux antifongiques. L'inactivation de YapA a engendré une hypersusceptibilité à l' H2O2, confirmant ainsi le rôle de ce gène dans la réponse au stress oxydatif chez A . fumigatus. La participation dans la résistance aux antifongiques des gènes codant pour des transporteurs ainsi que d'autres gènes identifiés par analyse du génome a été déterminée en testant leur niveau d'expression dans des souches résistantes à l'ITC. Bien qu'une surexpression de transporteurs ait été observée dans certaines souches, une corrélation entre la résistance à l'ITC et les niveaux d'expression de ces transporteurs n'a pu être clairement établie. Ce présent travail s'est donc porté sur l'étude de 2 autres mécanismes potentiellement impliqués dans la résistance aux azoles : 1) la surexpression de cyp51A codant pour l'enzyme cible et 2) des mutations dans cyp51A. Cependant, la surexpression de cyp51A dans les souches étudiées n'a pas été constatée. L'effet des mutations de cyp51A dans la résistance aux azoles a été testée par complémentation fonctionnelle d'une souche S. cerevisiae déletée dans son gène ERG11. L'expression de ces gènes chez S. cerevisiae a permis de démontrer que les protéines Cyp51Ap contenant une mutation G54E ou M220K pouvaient conférer une résistance spécifique à certains azoles, ainsi suggérant que ces mutations pourraient être importantes dans le développement d'une résistance aux azoles chez A. fumigatus. En conclusion, ce travail a permis de mettre en évidence, dans des souches d'A. fumigatus , une corrélation entre leur résistance à l' ITC et les mécanismes impliquant une surexpression de transporteurs et des mutations dans cyp51A. Cependant, ces mécanismes n'ont pu expliquer la résistance aux azoles de certaines souches et c'est pourquoi de nouvelles approches doivent être envisagées afin d'étudier ces mécanismes.
