The goal of the Iowa Child Death Review Team is to identify those risks or factors in childhood (ages 17 and under) that result in fatal outcomes through a retrospective review of child death cases. A multidisciplinary team approach to reviewing child death cases is conducted. Recommendations made by the Team are based on data, which then are used to identify trends that require systemic solutions. In reviewing the number of child deaths in years 2008 and 2009, one can quickly discern that child death rates declined from 2008 to 2009, decreasing from 386 to 311 deaths. The incidence of child death was higher in those counties with greater populations within our state.

Recombinant adeno-associated virus (rAAV) are effective gene delivery vehicles that can mediate long-lasting transgene expression. However, tight regulation and tissue-specific transgene expression is required for certain therapeutic applications. For regulatable expression from the liver we designed a hepatospecific bidirectional and autoregulatory tetracycline (Tet)-On system (Tet(bidir)Alb) flanked by AAV inverted terminal repeats (ITRs). We characterized the inducible hepatospecific system in comparison with an inducible ubiquitous expression system (Tet(bidir)CMV) using luciferase (luc). Although the ubiquitous system led to luc expression throughout the mouse, luc expression derived from the hepatospecific system was restricted to the liver. Interestingly, the induction rate of the Tet(bidir)Alb was significantly higher than that of Tet(bidir)CMV, whereas leakage of Tet(bidir)Alb was significantly lower. To evaluate the therapeutic potential of this vector, an AAV-Tet(bidir)-Alb-expressing interleukin-12 (IL-12) was tested in a murine model for hepatic colorectal metastasis. The vector induced dose-dependent levels of IL-12 and interferon-γ (IFN-γ), showing no significant toxicity. AAV-Tet(bidir)-Alb-IL-12 was highly efficient in preventing establishment of metastasis in the liver and induced an efficient T-cell memory response to tumor cells. Thus, we have demonstrated persistent, and inducible in vivo expression of a gene from a liver-specific Tet-On inducible construct delivered via an AAV vector and proved to be an efficient tool for treating liver cancer.

Studies on host-parasite relationships have commonly reported that parasitized hosts undergo changes in their behavioural and life history traits. How do these changes affect the fitness of the hosts? What are the ecological and evolutionary drivers of these changes? These open questions are crucial to predict the parasite spread amongst hosts. Surprisingly, mosquito vectors of diseases to humans and animals have long been seen as passive parasite transporters, being unaffected by the infection though they also function as hosts. Natural parasite-vector interactions are therefore poorly documented in the literature. In this thesis, we seek to address the role of wild vectors in the epidemiology of avian Plasmodium, the etiological agents of malaria in birds. We first conducted avian malaria surveys in field-caught mosquitoes to identify the natural vectors in our temperate study area. We report that ornithophilic Culex pipiens primarily act as a vector for Plasmodium vaughani in spring, this parasite species being progressively replaced by P. relictum along with the season. Season-related factors may thus shape the mosquitoes' vectorial capacity. We then used experimental approaches to determine the effect of avian malaria on wild, naturally infected C. pipiens. We show that infected mosquitoes incur unavoidable physiological costs associated with parasite exploitation, these costs being expressed as a reduced survival under nutritionally stressed conditions only. These results are of significant importance for the epidemiology of avian malaria since seasonal changes in climate may likely influence food quality and quantity available to the mosquitoes. The host-selection preferences of the vectors with respect to the malaria-infection status of their bird hosts largely determine the disease spreading. In a second laboratory experiment, we thus offered wild C. pipiens the opportunity to choose between uninfected and naturally infected great tits, Parus major. We show that host-seeking mosquitoes have innate orientation preferences for uninfected birds. This suggests that avian malaria parasites exert strong selective pressures on their vectors, pushing them to evolve anti-parasite behaviours. We lastly investigated the links between malaria-associated symptoms in birds and resulting attractiveness to the mosquitoes. We show that experimentally malaria-infected canaries, Serinus canaria, suffer severe haematocrit reduction at peak parasitaemia and reduced basal metabolic rate later in the course of the infection. However, no links between infection and bird attractiveness to the mosquitoes were shown in an experiment using canaries as live bait for mosquito trap in the field. These links may have been masked by confounding environmental factors. Using a system where the vectors, parasites and hosts co-occur in sympatry, this thesis illustrates that vectors are not always Plasmodium permissive, which opposes to the traditional view that malaria parasites should have little effect on their vectors. The way that the vectors respond to the parasite threat is largely determined by the environmental conditions. This may have major implications for the epidemiology of avian malaria. - Les études portant sur les relations hôtes-parasites mentionnent souvent que les hôtes parasités subissent des modifications de leurs traits d'histoire de vie ou bien comportementaux. Comment ces changements affectent-ils la valeur sélective des hôtes et celle de leurs parasites ? Quels sont les déterminants de ces modifications ? Ces questions sont d'un grand intérêt en épidémiologie. Pour autant, les moustiques vecteurs de maladies infectieuses ont longtemps été perçus comme de simples transporteurs de parasites, n'étant pas affectés par ces derniers. Cette thèse porte sur le rôle des vecteurs dans l'épidémiologie des Plasmodium aviaires, agents étiologiques de la malaria chez les oiseaux. Dans le but d'identifier les vecteurs naturels de malaria aviaire dans notre zone d'étude, nous avons tout d'abord collecté des moustiques sur le terrain, puis déterminé leur statut infectieux. Nous rapportons que les moustiques Culex pipiens sont principalement impliqués dans la transmission de Plasmodium vaughani au printemps, cette espèce de parasite étant progressivement remplacée par P. relictum au fil de la saison de transmission. Nous avons ensuite conduit une expérience visant à déterminer l'effet de la malaria aviaire sur des C. pipiens sauvages, naturellement infectés. Nous montrons que des coûts sont associés à l'infection pour les moustiques. Ces coûts occasionnent une diminution de la survie des vecteurs seulement lorsque ceux-ci sont privés de ressources nutritionnelles. Des changements saisonniers de climats pourraient affecter la quantité et la qualité des ressources disponibles pour les vecteurs et donc, leur aptitude à transmettre l'infection. Les traits comportementaux des moustiques vecteurs, tels que la recherche et le choix d'un hôte pour se nourrir, sont d'une importance majeure pour la dispersion de la malaria. Pour cela, nous avons offert à des C. pipiens sauvages l'opportunité de choisir simultanément entre une mésange charbonnière (Parus major) saine et une autre naturellement infectée. Nous montrons que les moustiques s'orientent préférentiellement vers des mésanges saines. Les Plasmodium aviaires exerceraient donc de fortes pressions de sélection sur leurs vecteurs, favorisant ainsi l'évolution de comportements d'évitement des parasites. Enfin nous avons cherché à identifier de potentiels liens entre symptômes de l'infection malarique chez les oiseaux et attractivité de ces derniers pour les moustiques. Nous montrons que des canaris (Serinus canaria) expérimentalement infectés sont fortement anémiés au moment du pic infectieux et que leur métabolisme basai diminue plus tard au cours de l'infection. Toutefois, aucun lien entre le statut infectieux et l'attractivité des canaris pour les moustiques n'a pu être montré lors d'une expérience réalisée en nature. Il se peut que ces liens aient été masqués par des facteurs environnementaux confondants. Dans son ensemble, cette thèse illustre que, contrairement aux idées reçues, les vecteurs de malaria aviaire ne sont pas toujours permissifs avec leurs parasites. L'environnement apparaît aussi comme un facteur déterminant dans la réponse des vecteurs face à la menace d'infection malarique. Cela pourrait fortement affecter l'épidémiologie de la malaria aviaire.

The General Assembly Line Balancing Problem with Setups (GALBPS) was recently defined in the literature. It adds sequence-dependent setup time considerations to the classical Simple Assembly Line Balancing Problem (SALBP) as follows: whenever a task is assigned next to another at the same workstation, a setup time must be added to compute the global workstation time, thereby providing the task sequence inside each workstation. This paper proposes over 50 priority-rule-based heuristic procedures to solve GALBPS, many of which are an improvement upon heuristic procedures published to date.
Novel insulated gamma and lentis retroviral vectors towards safer genetic modification of stem cells

In otherwise successful gene therapy trials insertional mutagenesis has resulted in leukemia. The identification of new short synthetic genetic insulator elements (GIE) which would both prevent such activation effects and shield the transgene from silencing, is a main challenge. Previous attempts with e.g. b-globin HS4, have met with poor efficacy and genetic instability. We have investigated potential improvement with two new candidate synthetic GIEs in SIN-gamma and lentiviral vectors. With each constructs two internal promoters have been tested: either the strong Fr- MuLV-U3 or the housekeeping hPGK.We could identify a specific combination of insulator 2 repeats which translates into best functional activity, high titers and boundary effect in both gammaretro and lentivectors. In target cells a dramatic shift of expression is observed with an homogenous profile the level of which strictly depends on the promoter strength. These data remain stable in both HeLa cells over three months and cord blood HSCs for two months, irrespective of the multiplicity of infection (MOI). In comparison, control native and SIN vectors expression levels show heterogeneous, depend on the MOI and prove unstable. We have undertaken genotoxicity assessment in comparing integration patterns ingenuity in human target cells sampled over three months using high-throughput pyro-sequencing. Data will be presented. Further genotoxicity assessment will include in vivo studies. We have established insulated vectors which harbour both boundary and enhancer-blocking effect and show stable in prolonged in vitro culture conditions.
