Are Parents the Key? How Parental Suicide Stigma and Suicide Literacy Affect Help-Seeking Attitudes and Intentions for their Child

Suicide is the leading cause of death among Australian young people, yet rates of help-seeking for suicidal ideation and behaviors in this population are concerningly low. In this study, the relationships between parental suicide stigma, parental suicide literacy, and their attitudes and intentions toward seeking professional help for their child if they were to express thoughts of suicide are investigated. Understanding this influence is critical given parents are key facilitators of their child's access to and engagement with professional mental health services. An online survey was administered to 302 parents of children aged-12-18 (Mage = 45.36, SDage = 6.23; 91.4% female). Parental suicide stigma was significantly associated with more negative help-seeking attitudes and lower help-seeking intentions. Other significant predictors of more positive help-seeking attitudes included parental self-efficacy and having a child with no history of suicidal ideation. Higher help-seeking intentions were associated with female gender, living in an urban area, and positive help-seeking attitudes. Parental suicide literacy was not significantly associated with help-seeking. Practically, outcomes of this study may inform the development and implementation of targeted education programs to increase parental help-seeking for their children.

Aneurysm of the inferior vena cava: case report

Venous aneurysms are uncommon. Despite their infrequency, venous aneurysms can present with significant clinical complications such as thrombosis, pulmonary embolism, and death. In this report, we present the case of a thrombosed inferior vena cava aneurysm discovered in a 16-year-old male who had deep vein thrombosis of the right lower extremity. Thrombosis of the inferior vena cava is uncommon in the pediatric population. Therefore, congenital abnormalities such as an inferior vena cava aneurysm should be considered when evaluating pediatric patients who present with deep vein thrombosis.

Synthesis of biologically active taxol analogs with modified phenylisoserine side chains

Taxol (1) is a highly potent antitumor agent, exerting its mechanism of action by promoting the assembly of stable microtubules in cells. We are reporting on the first synthesis and biological evaluation of taxol derivatives with substituted phenyl rings at the C-13 N-benzoyl-(2'R,3'S)-3'-phenylisoserine side chain of taxol (1). Two taxol derivatives were synthesized, one possessing a N-(p-chlorobenzoyl)-(2'R,3'S)-3'-phenylisoserine side chain (2) and the other one a N-benzoyl-(2'R,3'S)-3'-(p-chlorophenyl)isoserine side chain (3). The synthesis of the novel phenylisoserine side chains was achieved through the asymmetric synthesis of 3-hydroxy-4-aryl-2-azetidinone derivatives via the ester enolate-imine cyclocondensation reaction. The 2-azetidinones 14 and 15 were acylated with p-chlorobenzoyl chloride and benzoyl chloride, respectively, to form the N-acyl beta-lactams 16 and 17. Subsequent coupling of 16 and 17 to 7-(triethylsilyl)baccatin III (6) in the presence of pyridine and DMAP afforded, after removal of the protecting groups, the desired taxol analogues 2 and 3 in excellent yields. The newly synthesized derivatives 2 and 3 were tested in the tubulin assembly assay and also evaluated for their cytotoxicity against B16 melanoma cells. It was found that the taxol derivatives 2 and 3 had activity comparable to taxol (1).
