The Effects of Prenatal Education and Hospital Intervention on Breastfeeding Initiation

Breastfeeding is considered an important health practice for mothers and babies. However, Mississippi has the lowest breastfeeding rate of any state in the nation. Because of the numerous potential benefits of breastfeeding, the overall health of Mississippians could benefit from improved breastfeeding outcomes. Using 2010 data retrieved by the Pregnancy Risk Assessment Monitoring System (PRAMS) survey, which is administered through the Mississippi State Department of Health (MDH) in partnership with the Centers for Disease Control and Prevention (CDC), this study explores the factors that influence the breastfeeding decisions of mothers in Mississippi. In the PRAMS survey, women were asked whether a healthcare professional had talked to them about breastfeeding both during prenatal care visits and before discharge from the hospital. Their responses were analyzed using a logistic regression model to determine whether their decisions regarding breastfeeding initiation were influenced by the breastfeeding advice they received. Existing literature shows that women who are offered support from health professionals are more likely to breastfeed their children than those without support. This study supports this claim, showing that mothers who spoke with a healthcare worker both during prenatal visits and before discharge from the hospital were more likely to initiate breastfeeding than women who spoke with a healthcare worker just once or not at all. This knowledge can be useful in efforts to improve breastfeeding outcomes and in inspiring further research

Protein kinase C-dependent signaling controls the midgut epithelial barrier to malaria parasite infection in anopheline mosquitoes.

Anopheline mosquitoes are the primary vectors of parasites in the genus Plasmodium, the causative agents of malaria. Malaria parasites undergo a series of complex transformations upon ingestion by the mosquito host. During this process, the physical barrier of the midgut epithelium, along with innate immune defenses, functionally restrict parasite development. Although these defenses have been studied for some time, the regulatory factors that control them are poorly understood. The protein kinase C (PKC) gene family consists of serine/threonine kinases that serve as central signaling molecules and regulators of a broad spectrum of cellular processes including epithelial barrier function and immunity. Indeed, PKCs are highly conserved, ranging from 7 isoforms in Drosophila to 16 isoforms in mammals, yet none have been identified in mosquitoes. Despite conservation of the PKC gene family and their potential as targets for transmission-blocking strategies for malaria, no direct connections between PKCs, the mosquito immune response or epithelial barrier integrity are known. Here, we identify and characterize six PKC gene family members--PKCδ, PKCε, PKCζ, PKD, PKN, and an indeterminate conventional PKC--in Anopheles gambiae and Anopheles stephensi. Sequence and phylogenetic analyses of the anopheline PKCs support most subfamily assignments. All six PKCs are expressed in the midgut epithelia of A. gambiae and A. stephensi post-blood feeding, indicating availability for signaling in a tissue that is critical for malaria parasite development. Although inhibition of PKC enzymatic activity decreased NF-κB-regulated anti-microbial peptide expression in mosquito cells in vitro, PKC inhibition had no effect on expression of a panel of immune genes in the midgut epithelium in vivo. PKC inhibition did, however, significantly increase midgut barrier integrity and decrease development of P. falciparum oocysts in A. stephensi, suggesting that PKC-dependent signaling is a negative regulator of epithelial barrier function and a potential new target for transmission-blocking strategies

Feasibility Assessment of Special Management Areas to Enhance Recreational Fisheries and Habitat

Nearshore recreational fisheries provide tremendous value to the Florida economy. These fisheries are dependent on the availability of high-quality habitat, and sound fisheries management. Habitat can be degraded by several factors, including damage to seagrass flats by propellers of power boats operating in shallow waters (prop scarring). The current fisheries management framework employs regulations limiting harvest by season, fish length, and bag limit (number of fish harvestable per angler per day). Regulations often vary due to regional differences in fishery stocks and population dynamics. Our team’s overall goal in undertaking this work was to assess the feasibility of creating special fisheries and habitat management areas by completing a holistic review of the relevant biological, socioeconomic, and legal aspects of such areas, using Citrus County as a model. In this report, we will detail findings related to 1) status of propeller scarring in the St. Martins Keys area, 2) legal analysis of options for seagrass protection and special fisheries management areas, 3) possible effects of management actions on fisheries, including a comparative analysis of existing relevant spatial management

Navigating to new frontiers in behavioral neuroscience: traditional neuropsychological tests predict human performance on a rodent-inspired radial-arm maze

We constructed an 11-arm, walk-through, human radial-arm maze (HRAM) as a translational instrument to compare existing methodology in the areas of rodent and human learning and memory research. The HRAM, utilized here, serves as an intermediary test between the classic rat radial-arm maze (RAM) and standard human neuropsychological and cognitive tests. We show that the HRAM is a useful instrument to examine working memory ability, explore the relationships between rodent and human memory and cognition models, and evaluate factors that contribute to human navigational ability. One-hundred-and-fifty-seven participants were tested on the HRAM, and scores were compared to performance on a standard cognitive battery focused on episodic memory, working memory capacity, and visuospatial ability. We found that errors on the HRAM increased as working memory demand became elevated, similar to the pattern typically seen in rodents, and that for this task, performance appears similar to Miller's classic description of a processing-inclusive human working memory capacity of 7 ± 2 items. Regression analysis revealed that measures of working memory capacity and visuospatial ability accounted for a large proportion of variance in HRAM scores, while measures of episodic memory and general intelligence did not serve as significant predictors of HRAM performance. We present the HRAM as a novel instrument for measuring navigational behavior in humans, as is traditionally done in basic science studies evaluating rodent learning and memory, thus providing a useful tool to help connect and translate between human and rodent models of cognitive functioning
