Reduced Levels of Brain-Derived Neurotrophic Factor Affect Body Weight, Brain Weight and Behavior.

Neurotrophins, which belong to the family of growth factors, not only play crucial roles during development but are also involved in many processes in the postnatal brain. One representative of neurotrophins is brain-derived neurotrophic factor (BDNF). BDNF plays a role in the regulation of body weight and neuronal plasticity and is, therefore, also involved in processes associated with learning and memory formation.

Testing the Preliminary Validity of a Multidimensional Framework for Studying the Effects of Cancer Health Literacy on Cancer Screening Behaviors among Diverse Populations.

The objective of this study was to evaluate the applicability of a multidimensional framework to explore factors associated with cancer literacy and its effects on receiving cancer screenings among diverse populations. Based on the conceptual framework, we developed and pilot-tested the Multidimensional Cancer Literacy Questionnaire (MCLQ) among 1500 individuals (African Americans, Latinos and Whites) in Louisiana. Exploratory factor analysis was used to identify the MCLQ underlying structure and predominant factors explaining each of the dimensions in the model.

Outcomes Following Orbital Floor Fractures in the Elderly.

Background: Orbital floor fractures in the elderly are controversial, with varying guidelines on indications for operative and nonoperative management. Morbidity includes changes to ocular position, inferior rectus muscle injury, and damage to the neurovascular bundle as it traverses the orbital floor. Across all facial fractures, the elderly are less frequently operated on, albeit longer hospital stays and more probably ICU admission.

Thin and Ultra-Thin Split-Thickness Skin Grafts Are Safe and Efficacious in the Burn Population.

Split-thickness skin-grafts are a mainstay of burn management. Studies suggest no benefit to using thick (0.025 inch) over standard (0.

Cancer Health Literacy and Willingness to Participate in Cancer Research and Donate Bio-Specimens.

Although it has been well documented that poor health literacy is associated with limited participation in cancer clinical trials, studies assessing the relationships between cancer health literacy (CHL) and participation in research among diverse populations are lacking. In this study, we examined the relationship between CHL and willingness to participate in cancer research and/or donate bio-specimens (WPRDB) among African Americans, Latinos, and Whites. Participants completed the Cancer Health Literacy Test and the Multidimensional Cancer Literacy Questionnaire.

Ewing Sarcoma Presenting as a Congenital Scalp Mass.

Ewing sarcoma is a locally aggressive, highly malignant tumor most commonly seen in the skeletal system. The "Ewing family of tumors" also includes other tissue types that are not common, such as soft tissue origin classified as extraosseous Ewing sarcoma (EES) or primitive neuroendocrine origin. Age of onset most often occurs within the first 2 decades of life.

Interobserver Reproducibility Among Gynecologic Pathologists in Diagnosing Heterologous Osteosarcomatous Component in Gynecologic Tract Carcinosarcomas.

Distinguishing hyalinized stroma from osteoid production by a heterologous osteosarcomatous component can be challenging in gynecologic tract carcinosarcomas. As heterologous components in a carcinosarcoma may have prognostic and therapeutic implications, it is important that these are recognized. This study examines interobserver reproducibility among gynecologic pathologists in the diagnosis of osteosarcomatous components, and its correlation with expression of the novel antibody SATB2 (marker of osteoblastic differentiation) in these osteosarcomatous foci.

The Effects of Molding Helmet Therapy on Spring-Mediated Cranial Vault Remodeling for Sagittal Craniosynostosis.

There is no clear consensus for the optimal treatment of sagittal craniosynostosis; however, recent studies suggest that improved neurocognitive outcomes may be obtained when surgical intervention imparts active cranial expansion or remodeling and is performed before 6 months of age. The authors consider spring-mediated cranioplasty (SMC) to optimally address these imperatives, and this is an investigation of how helmet orthoses before or after SMC affect aesthetic outcomes.The authors retrospectively evaluated patients treated with SMC and adjunct helmeting for sagittal synostosis.

Detection of female lower genital tract dysplasia using orally administered 5-aminolevulinic acid induced protoporphyrin IX: a preliminary study.

Objective: Previous studies have suggested that 5-aminolevulinic acid (ALA) may be used topically on the cervix to allow optical detection of cervical dysplasia, based on the fluorescence of protoporphyrin IX (PpIX) synthesized in situ from ALA. However, the uniformity of distribution of topically applied PpIX and the sensitivity and specificity of detection are not optimal. The current study was undertaken to demonstrate the feasibility of administering ALA by mouth (po) with the hypothesis that systemic administration might provide a more reliable diagnostic tool.
