Comparison of major depression diagnostic classification probability using the SCID, CIDI, and MINI diagnostic interviews among women in pregnancy or postpartum: An individual participant data meta-analysis
Objectives A previous individual participant data meta-analysis (IPDMA) identified differences in major depression classification rates between different diagnostic interviews, controlling for depressive symptoms on the basis of the Patient Health Questionnaire-9. We aimed to determine whether similar results would be seen in a different population, using studies that administered the Edinburgh Postnatal Depression Scale (EPDS) in pregnancy or postpartum. Methods Data accrued for an EPDS diagnostic accuracy IPDMA were analysed. Binomial generalised linear mixed models were fit to compare depression classification odds for the Mini International Neuropsychiatric Interview (MINI), Composite International Diagnostic Interview (CIDI), and Structured Clinical Interview for DSM (SCID), controlling for EPDS scores and participant characteristics. Results Among fully structured interviews, the MINI (15 studies, 2,532 participants, 342 major depression cases) classified depression more often than the CIDI (3 studies, 2,948 participants, 194 major depression cases; adjusted odds ratio [aOR] = 3.72, 95% confidence interval [CI] [1.21, 11.43]). Compared with the semistructured SCID (28 studies, 7,403 participants, 1,027 major depression cases), odds with the CIDI (interaction aOR = 0.88, 95% CI [0.85, 0.92]) and MINI (interaction aOR = 0.95, 95% CI [0.92, 0.99]) increased less as EPDS scores increased. Conclusion Different interviews may not classify major depression equivalently
Differences in MMPI-2 personality profiles among filicide and homicide women
Introduction. Filicide is an act of terrible violence that generates dismay and astonishment and invites everybody to ask: why? Aim. As the transition to motherhood is a critical period for any woman, requiring the activation of deep personality resources, the aim of this study was to deepen our knowledge of the personality profiles of new mothers by comparing a sample of 16 women who had killed their own child (“filicide mothers”) with women who had murdered someone outside of their family (“non-family homicide women”). Method. All of the women had a similar psychiatric diagnosis, as assessed by the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). All were assessed by the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) 2 to 4 years after the court’s judgment. A Kruskal-Wallis test and two-step cluster analysis were performed to determine whether a specific personality profile could distinguish filicide mothers from non-family homicide women. Results. Years after the act, few filicide mothers showed symptoms of psychopathology; rather, they appeared functional and untroubled. In contrast, non-family homicide women showed a pathological mean profile. Conclusions. The results may indicate conscious attempts made by filicide mothers to avoid negative evaluations, minimize symptoms, and deny psychological suffering. These may indicate personality risk factors that could help clinicians recognize and intervene in cases where a woman presents a severe mental illness before, during, and following the birth of her child

Diapause in a tropical oil-collecting bee: molecular basis unveiled by RNA-Seq
Abstract Background Diapause is a natural phenomenon characterized by an arrest in development that ensures the survival of organisms under extreme environmental conditions. The process has been well documented in arthropods. However, its molecular basis has been mainly studied in species from temperate zones, leaving a knowledge gap of this phenomenon in tropical species. In the present study, the Neotropical and solitary bee Tetrapedia diversipes was employed as a model for investigating diapause in species from tropical zones. Being a bivoltine insect, Tetrapedia diversipes produce two generations of offspring per year. The first generation, normally born during the wet season, develops faster than individuals from the second generation, born after the dry season. Furthermore, it has been shown that the development of the progeny, of the second generation, is halted at the 5th larval instar, and remains in larval diapause during the dry season. Towards the goal of gaining a better understanding of the diapause phenomenon we compared the global gene expression pattern, in larvae, from both reproductive generations and during diapause. The results demonstrate that there are similarities in the observed gene expression patterns to those already described for temperate climate models, and also identify diapause-related genes that have not been previously reported in the literature. Results The RNA-Seq analysis identified 2275 differentially expressed transcripts, of which 1167 were annotated. Of these genes, during diapause, 352 were upregulated and 815 were downregulated. According to their biological functions, these genes were categorized into the following groups: cellular detoxification, cytoskeleton, cuticle, sterol and lipid metabolism, cell cycle, heat shock proteins, immune response, circadian clock, and epigenetic control. Conclusion Many of the identified genes have already been described as being related to diapause; however, new genes were discovered, for the first time, in this study. Among those, we highlight: Niemann-Pick type C1, NPC2 and Acyl-CoA binding protein homolog (all involved in ecdysteroid synthesis); RhoBTB2 and SASH1 (associated with cell cycle regulation) and Histone acetyltransferase KAT7 (related to epigenetic transcriptional regulation). The results presented here add important findings to the understanding of diapause in tropical species, thus increasing the comprehension of diapause-related molecular mechanisms
