Background Co-morbidity of mood and anxiety disorders is common and often associated with greater illness severity. This study investigates clinical correlates and familiality of four anxiety disorders in a large sample of bipolar disorder (BP) and major depressive disorder (MDD) pedigrees. Method The sample comprised 566 BP families with 1416 affected subjects and 675 MDD families with 1726 affected subjects. Clinical characteristics and familiality of panic disorder, social phobia, specific phobia and obsessivecompulsive disorder (OCD] were examined in BP and MDD pedigrees with multivariate modeling using generalized estimating equations. Results Co-morbidity between mood and anxiety disorders was associated with several markers of clinical severity, including earlier age of onset, greater number of depressive episodes and higher prevalence of attempted suicide, when compared with mood disorder without co-morbid anxiety. Familial aggregation was found with co-morbid panic and OCD in both BP and MDD pedigrees. Specific phobia showed familial aggregation in both MDD and BP families, although the findings in BP were just short of statistical significance after adjusting for other anxiety co-morbidities. We found no evidence for familiality of social phobia. Conclusions Our findings suggest that co-morbidity of MDD and BP with specific anxiety disorders [OCD, panic disorder and specific phobia] is at least partly due to familial factors, which may be of relevance to both phenotypic and genetic studies of co-morbidity.

This study investigated psychological help-seeking behavior and sexual identity on perceptions of masculinity and femininity. Participants rated masculine and feminine characteristics of a fictitious man portrayed in a vignette. The vignettes were rated by 292 women and 111 men and portrayed either a heterosexual or gay depressed man who was either seeking psychological help or not seeking psychological help. The results of this study showed that psychological help-seeking behavior and sexual identity did not significantly influence perceptions of masculinity, but significantly contributed to perceptions of femininity. In addition, traditional masculine ideology and modern homonegativity were related to negative attitudes toward seeking psychological help.

Since the discovery of anaplastic lymphocyte kinase (ALK) rearrangement in non-small cell lung cancer (NSCLC) and subsequent development of increasingly effective and central nervous system (CNS)-penetrant first-generation, second-generation and third-generation ALK tyrosine kinase inhibitors (TKIs), the landscape of resistance mechanisms and treatment decisions has become increasingly complex. Tissue and/or plasma-based molecular tests can identify not only the rearrangement proper but also common resistance mechanisms to guide decision-making for further lines of treatment. However, frequently encountered questions exist regarding how to diagnosis ALK rearrangement, how to select a first-line ALK TKI, how to diagnose and manage ALK TKI resistance, how to control CNS disease and how to handle failure of ALK inhibition. Herein, we attempt to answer these questions through the evidence-based interpretation of studies on ALK-rearranged NSCLC combined with experience gained from our institution. The authors also propose a therapeutic algorithm for the management of this complex and highly treatable disease to assist clinicians globally in the treatment of patients with ALK-positive NSCLC.
