ABSTRACT
In sorrow thou shalt bring forth children (Genesis 3:16) seems as relevant today, with one of seven mothers afflicted by a depressive episode, constituting the most common medical complication after delivery. Why mothers are variably affected by mood symptoms postpartum remains unclear, and the pathogenesis and early molecular indicators of this divergent outcome have not been described. We applied a case-control design comparing differential global gene expression profiles in blood mononuclear cells sampled shortly after delivery at the time of inception of postpartum depression (PD). Nine antidepressant naive mothers showing high depressive scores and developing a persisting major depressive episode with postpartum onset were compared with 10 mothers showing low depressive scores and no depressive symptoms on prospective follow-up. A distinctive gene expression signature was observed after delivery among mothers with an emergent PD, with a significant overabundance of transcripts showing a high-fold differential expression between groups, and correlating with depressive symptom severity among all mothers. Early expression signatures correctly classified the majority of PD patients and controls. Those developing persisting PD exhibit a relative downregulation of transcription after delivery, with differential immune activation, and decreased transcriptional engagement in cell proliferation, and DNA replication and repair processes. Our data provide initial evidence indicating that blood cells sampled shortly after delivery may harbor valuable prognostic information for identifying the onset of persisting PD. Some of the informative transcripts and pathways may be implicated in the differential vulnerability that underlies depression pathogenesis.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, where family data support substantial heritability.(1) To date, association studies focussed mainly on genes regulating dopaminergic neurotransmission.(2)Interleukin-1 (IL-1) activity in the brain has been implicated with differentiation of dopaminergic neurons(3,4) and modulation of central monoaminergic reactivity.(5) We investigated the role of interleukin-1 receptor antagonist (IL-1Ra) gene variable number tandem repeat (VNTR) polymorphism,(6) in a sample of 86 children with DSM-IV ADHD and their parents. Transmission disequilibrium analysis showed increased transmission of the IL-1Ra 4-repeat allele (chi(2) = 4.07, P = 0.04) and decreased transmission of the 2-repeat allele (chi(2) = 4.59, P = 0.03) to affected children. The 4-repeat allele was associated with a significantly increased risk for ADHD (chi(2) = 4.46, df 1, P = 0.035, RR = 1.292, 95% CI 1.01-1.66). The IL-1Ra 2-repeat allele was associated with a significantly decreased risk for ADHD (chi(2) = 4.65, df 1, P = 0.03, RR = 0.763, 95% CI 0.59-0.98). If replicated, this finding may point to a role for brain cytokine activity in the etiopathogenesis of ADHD.

Attachment between parent and child plays a crucial role in the healthy development of the child. Accordingly disturbances in parental bonding will be linked with the development of mental disorders later in life. The present study examines the relationship between parental bonding and mental health in healthy adolescents. Participants were 847 Israeli high school students who completed the Parental Bonding Instrument (PBI), the Brief Symptom Inventory (BSI), the General Well-Being (GWB), the Perceived Social Support (PSS), and the Social Desirability scale (SDS). In general, Israeli adolescents reported more parental care and less control than did Australian adolescents and adults. Female subjects reported more maternal care than did males. Subjects who reported high care and low control (optimal bonding) reported less distress, better general well-being and better social support that did all other groups. In contrast, those who reported low care and high control (affectionless control bonding) had the highest BSI scores and the lowest GWB and PSS scores. These results are in line with Bowlby's theory of attachment. They also show that specific configuration of parental bonding are linked with distress and isolation in adolescents.

The systematic study of antipsychotic-induced movement disorders in young psychiatric patients is very sparse. We assessed the presence of tardive dyskinesia in an adolescent in-patient psychiatric ward. Eighteen per cent (3/17) exhibited either pronounced or subtle signs of tardive dyskinesia. Our study suggests that young psychiatric patients may develop signs of tardive dyskinesia even though they are exposed to relatively short-term neuroleptic treatment and at dosages that are relatively low. We advocate frequent and systematic monitoring of adolescent patients taking antipsychotic drugs in order to minimize the emergence of this long-term, troublesome complication of neuroleptic drugs.

We have described several immune derangements found in a clinically asymptomatic group of 117 male homosexuals (MHS) in Israel. These consisted of a marked decrease in TH and TS cells, decreased NK and allogeneic response, and increased levels of acid labile alpha-interferon and circulating immune complexes (CIC). Most of these alterations were found in approximately 40% of the subjects, with no simple correlation between them. Since Israel is a low incidence area for AIDS and related syndromes, it is suggested that this situation reflects a common situation among asymptomatic MHS in general, although the reasons for these impairments are not clear. This situation may therefore explain susceptibility of the male homosexual for developing AIDS, given the appropriate circumstances, environment, and genetic background.
