Sexual Health Education in Georgia: A Role for Reducing Sexually Transmitted Infections Among Adolescents

Background: In Georgia, sexually transmitted infections (STIs) are a substantial health issue, particularly among young adults in vulnerable and minority populations. The United States Preventive Services Task Force recommends that sexually active adolescents and at-risk adults receive behavioral counseling and education in primary care settings, community organizations, departments of health, and schools. Methods: The present approach used in Georgia for educating adolescents at high risk for STIs about these diseases was assessed. The data collected included standards for sexual health education, survey results from educators and students, and observations from a pilot study with adolescents detained by the juvenile justice system. Results: In Georgia, most health educators for middle (87.3%) and high (93.8%) schools have health and/or physical education backgrounds. They indicated a need for further education about STIs. For grades 6-12, 24% of students reported that they had not received HIV/AIDS education during the academic year. Preliminary observations from a study with juvenile detainees indicate that this population has limited knowledge about STIs, their effects and modes of transmission. Conclusion: Sexual health education, including that for HIV/AIDS, is essential to curtail the STI crisis, and educational endeavors should be culturally sensitive and evidence-based. In Georgia, many citizens, including teachers, are not adequately equipped to make informed decisions regarding STI risk. Georgia, home to the Centers for Disease Control and Prevention, is in a unique position to adapt evidence-based sexual health interventions for its population

Reflections on Mental Health Advocacy Across Differing Ecological Levels

Background: According to the World Health Organization, mental health advocacy is comprised of a range of actions designed to change aspects of attitudes and structures that impede the achievement of positive mental health in populations. Methods: According to the World Health Organization, mental health advocacy is comprised of a range of actions designed to change aspects of attitudes and structures that impede the achievement of positive mental health in populations. Results: We have proposed interventions and advocacy effort for each ecological level. Project UPLIFT, a distance-delivered intervention for mental health is presented as an example of an effort that can affect several levels of the social ecology. Conclusions: Advocacy and interventions that make an effort to encompass the levels of the social-ecological model may contribute to greater progress in improving mental health outcomes

d-Amino acid oxidase and serine racemase in human brain: normal distribution and altered expression in schizophrenia

The N-methyl-d-aspartate receptor co-agonist d-serine is synthesized by serine racemase and degraded by d-amino acid oxidase. Both d-serine and its metabolizing enzymes are implicated in N-methyl-d-aspartate receptor hypofunction thought to occur in schizophrenia. We studied d-amino acid oxidase and serine racemase immunohistochemically in several brain regions and compared their immunoreactivity and their mRNA levels in the cerebellum and dorsolateral prefrontal cortex in schizophrenia. d-Amino acid oxidase immunoreactivity was abundant in glia, especially Bergmann glia, of the cerebellum, whereas in prefrontal cortex, hippocampus and substantia nigra, it was predominantly neuronal. Serine racemase was principally glial in all regions examined and demonstrated prominent white matter staining. In schizophrenia, d-amino acid oxidase mRNA was increased in the cerebellum, and as a trend for protein. Serine racemase was increased in schizophrenia in the dorsolateral prefrontal cortex but not in cerebellum, while serine racemase mRNA was unchanged in both regions. Administration of haloperidol to rats did not significantly affect serine racemase or d-amino acid oxidase levels. These findings establish the major cell types wherein serine racemase and d-amino acid oxidase are expressed in human brain and provide some support for aberrant d-serine metabolism in schizophrenia. However, they raise further questions as to the roles of d-amino acid oxidase and serine racemase in both physiological and pathophysiological processes in the brain

A high-throughput analysis of high-resolution X-ray CT images of stems of olive and citrus plants resistant and susceptible to Xylella fastidiosa

The bacterial plant pathogen Xylella fastidiosa causes disease in several globally important crops. However, some cultivars harbour reduced bacterial loads and express few symptoms. Evidence considering plant species in isolation suggests xylem structure influences cultivar susceptibility to X. fastidiosa. We test this theory more broadly by analysing high-resolution synchrotron X-ray computed tomography of healthy and infected plant vasculature from two taxonomic groups containing susceptible and resistant varieties: two citrus cultivars (sweet orange cv. Pera, tangor cv. Murcott) and two olive cultivars (Koroneiki, Leccino). Results found the susceptible plants had more vessels than resistant ones, which could promote within-host pathogen spread. However, features associated with resistance were not shared by citrus and olive. While xylem vessels in resistant citrus stems had comparable diameters to those in susceptible plants, resistant olives had narrower vessels that could limit biofilm spread. And while differences among olive cultivars were not detected, results suggest greater vascular connectivity in resistant compared to susceptible citrus plants. We hypothesize that this provides alternate flow paths for sustaining hydraulic functionality under infection. In summary, this work elucidates different physiological resistance mechanisms between two taxonomic groups, while supporting the existence of an intertaxonomical metric that could speed up the identification of candidate-resistant plants.</p
