Influencing Factors on Suicide in Correctional Settings

Suicide in correctional facilities is a major issue institutions have to face on a daily basis. Identifying potential risks and factors could help prevent suicide as well as aid in the foundation of more rehabilitative programs. This paper examines suicide and the main factors that influence this phenomenon.

Characterization of L-Serine Deaminase and its Potential Role in the Pathogenicity of Pseudomonas aeruginosa

All pathogens require high energetic influxes to counterattack the host immune system and without this energy bacterial infections are easily cleared. This study is an investigation into one highly bioenergetic pathway in Pseudomonas aeruginosa involving the amino acid L-serine and the enzyme L-serine deaminase (L-SD). P. aeruginosa is an opportunistic pathogen causing infections in patients with compromised immune systems as well as patients with cystic fibrosis. Recent evidence has linked L-SD directly to the pathogenicity of several organisms including but not limited to Campylobacter jejuni, Mycobacterium bovis, Streptococcus pyogenes, and Yersinia pestis. We hypothesized that P. aeruginosa L-SD is likely to be critical for its virulence. Genome sequence analysis revealed the presence of two L-SD homo logs encoded by sdaA and sdaB. We analyzed the ability of P. aeruginosa to utilize serine and the role of SdaA and SdaB in serine deamination by comparing mutant strains of sdaA (PAOsdaA) and sdaB (PAOsdaB) with their isogenic parent P. aeruginosa P AO 1. We demonstrated that P. aeruginosa is unable to use serine as a sole carbon source. However, serine utilization is enhanced in the presence of glycine and this glycine-dependent induction of L-SD activity requires the inducer serine. The amino acid leucine was shown to inhibit L-SD activity from both SdaA and SdaB and the net contribution to L-serine deamination by SdaA and SdaB was ascertained at 34% and 66 %, respectively. These results suggest that P. aeruginosa LSD is quite different from the characterized E. coli L-SD that is glycine-independent but leucine-dependent for activation. Growth mutants able to use serine as a sole carbon source were also isolated and in addition, suicide vectors were constructed which allow for selective mutation of the sdaA and sdaB genes on any P. aeruginosa strain of interest. Future studies with a double mutant will reveal the importance of these genes for pathogenicity.

Evaluation of a mentored self -help intervention for the management of psychotic symptoms

Cognitive behavioral therapy has been shown to be promising for the treatment of individuals experiencing psychotic symptoms, who are often diagnosed with schizophrenia. Using a non-random non-equivalent comparison group design (n = 26), this study explores whether an individually mentored self-help and self-paced intervention based upon cognitive behavioral approaches to auditory hallucinations or "hearing voices" makes a significant positive difference for individuals with major mental disorder diagnoses and psychotic symptoms who are residing in the community and receiving community mental health services. The mentored self-help intervention uses a workbook (Coleman & Smith, 1997) that stemmed from the British psychiatric survivor and "voice hearers"' movements and from cognitive behavioral approaches to treating psychotic symptoms. Thirty individuals entered the study. Pre- and post-intervention assessments of 15 participants in the intervention group and 11 participants in the comparison group were carried out using standardized instruments, including the Rosenberg Self-Esteem Scale, the Brief Psychiatric Rating Scale, and the Hoosier Assurance Plan Inventory - Adult. Four specific research questions address whether levels of self-esteem, overall psychotic symptoms, depression-anxiety, and disruption in life improved in the intervention group, relative to the comparison group. Pre- and post-assessment scores were analyzed using repeated measures analysis of variance. Results showed no significant difference on any measure, with the exception of the Brief Psychiatric Rating subscale for Anxious Depression, which showed a statistically significant pre-post difference with a strong effect size. A conservative interpretation of this single positive result is that it is due to chance. An alternative interpretation is that the mentored self-help intervention made an actual improvement in the level of depression-anxiety experienced by participants. If so, this is particularly important given high levels of depression and suicide among individuals diagnosed with schizophrenia. This alternative interpretation supports further research on the intervention utilized in this study. ^

South Road

SOUTH ROAD, a novel told in third-person limited, follows Adrienne Harris as she navigates the trials of her coming-of-age summer and then must deal with the aftermath. 1997: seventeen-year-old Adrienne Harris wants nothing more than to flee her eccentric grandmother’s rule and leave Harbor Point and never look back. When she meets her new neighbors, Adrienne knows her life will never be the same. Adrienne quickly falls in love with the charismatic Quinn Merritt. They decide to keep their relationship a secret since both families disapprove. This secret starts a chain reaction that seemingly leads to the suicide of the troubled and poetic Lucas Merritt. The summer culminates with Adrienne running away, pregnant and heartbroken. 2011: thirty-one-year-old Adrienne is an out of work line cook and single mother. The story opens as Adrienne reluctantly returns home to Harbor Point to care for her ailing grandmother. Once home, Adrienne has to confront the things that haunt her—the summer she met and lost both Merritt brothers, and also her dysfunctional relationship with her grandmother—in order to heal and repair her own life and her relationship with her daughter. In the end, Adrienne discovers many truths that alter her perception of her past in Harbor Point. Adrienne is finally able to move forward and start to build a life for her and her daughter. Harbor Point, the last place in the world Adrienne Harris wanted to be, turns out to be the only place she wants to call home.
