The association between transient childhood psychotic experiences and psychosocial outcomes in young adulthood: Examining the role of mental disorders and adult attachment

Aim

Evidence suggest individuals with mental disorders and psychotic experiences (PE), even transient PE, show poorer psychosocial outcomes relative to those with mental disorders. The concept of “attachment” is hypothesized as the mechanism by which people seek support in times of need. This can be measured as discrete styles or as positive (low avoidance/anxiety)/negative (high avoidance/anxiety) dimensions. Adult attachment has previously been examined on PE risk factors, but not outcomes. This study aimed to examine the relationship between transient childhood PE and adult psychosocial outcomes, comparing those with and without mental disorders. Second, to examine the role of adult attachment.

Method

Participants (n = 103) attended baseline (age 11–13) and 10-year follow-up. PE and mental disorders were measured using the Schedule for Affective Disorders and Schizophrenia for School-aged Children. Attachment and outcomes were measured using self-report measures. Analysis compared those with PE (with/without mental disorders), and mental disorders without PE, to controls, using linear and Poisson regression.

Results

PE was associated with lower self-esteem (β = −2.28, p = .03), perceived social support from friends (β = −2.80, p = .01), and higher stress in platonic relationships (IRR = 1.64). PE and mental disorders were associated with lower self-esteem (β = −5.74, p = .002), higher stress in romantic (IRR = 1.40) and platonic (IRR = 1.59) relationships, general stress (β = 5.60, p = .006), and mental distress (β = 5.67, p = .001). Mental disorders alone was not associated with any measure. Adult attachment dimensions attenuated some results.

Conclusions

This paper illustrates the association between transient PE and adult psychosocial outcomes, with & without co-occurring mental disorders, and demonstrates the role of adult attachment.     

Early proliferation of CCR5(+) CD38(+++) antigen-specific CD4(+) Th1 effector cells during primary HIV-1 infection

We investigated whether HIV-1 antigen-specific CD4(+) T cells expressed the viral coreceptor CCR5 during primary HIV-1 infection (PHI). In the peripheral blood of subjects with very early PHI (< 22 days after onset of symptoms), there was a 10- to 20-fold increase in the proportion of highly activated (CD38(+++)) and proliferating (Ki-67(+)) CD4(+) T cells that expressed CCR5(+), and were mostly T-cell intracellular antigen-1 (TIA-1)(+) perforin(+) granzyme B(+). Inthe same patient samples, CD4(+) T cells producing interferon (IFN)-gamma in response to HIV group-specific antigen (Gag) peptides were readily detected (median, 0.58%) by intracellular cytokine assay-these cells were again predominantly CD38(+++), Ki-67(+), and TIA-(++), as well as Bcl-2(low). On average, 20% of the Gag-specific CD4(+) T cells also expressed interleukin-2 (IL-2) and were CD127 (IL-7R)(+). Taken together, these results suggest that Gag-specific T-helper 1 (Th1) effector cells express CCR5 during the primary response and may include precursors of long-term self-renewing memory cells. However, in PHI subjects with later presentation, antigen-specific CD4(+) T cells could not be readily detected (median, 0.08%), coinciding with a 5-fold lower level of the CCR5(+)CD38(+++) CD4(+) T cells. These results suggest that the antiviral response to HIV-1 infection includes highly activated CCR5(+)CD4(+) cytotoxic effector cells, which are susceptible to both apoptosis and cytopathic infection with HIV-1, and rapidly decline.     

Neurocognition in the Extended Psychosis Phenotype: Performance of a Community Sample of Adolescents With Psychotic Symptoms on the MATRICS Neurocognitive Battery

Neurocognitive dysfunction is well established in psychosis, but recent work suggests that processing speed deficits might represent a particularly important cognitive deficit. A number of significant confounds, however, such as disease chronicity and antipsychotic medication use, have been shown to affect processing speed, causing debate as to the core cognitive features of psychosis. We adopted a novel strategy of testing neurocognitive performance in the “extended psychosis phenotype,” involving community-based adolescents who are not clinically psychotic but who report psychotic symptoms and who are at increased risk of psychosis in adulthood. This allows investigation of the earliest cognitive factors associated with psychosis risk, while excluding potential confounds such as disease chronicity and antipsychotic use. A population sample of 212 school-going adolescents aged 11–13 years took part in this study. Psychotic symptoms were assessed using the psychosis section of the Schedule for Affective Disorders and Schizophrenia. Neurocognition was assessed using the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) consensus neurocognitive battery. Adolescents with psychotic symptoms performed significantly more poorly on 3 processing speed tasks: Trail Making Test-A (F = 3.3, P < .05), Trail Making Test-B (F = 3.1, P < .05), and digit symbol coding task (F = 7.0, P < .001)—as well as on a nonverbal working memory (spatial span) task (F = 3.2, P < .05). Our findings support the idea that neurocognitive impairment, and processing speed impairment in particular, is a core feature of psychosis risk. This group likely demonstrates some of the earliest cognitive impairments associated with psychosis vulnerability.Key words: epidemiology/adolescents/cognitionKey words: epidemiology, adolescents, cognition     

Monosomy 7 syndrome in an infant with neurofibromatosis.

A 9-month-old boy with known familial neurofibromatosis type I (NF-1) presented with a clinical and laboratory picture suggestive of juvenile chronic myelomonocytic leukemia (JCMMoL). Chromosomal studies obtained from the bone marrow indicated, however, that he had monosomy 7 syndrome. We believe this is the first reported case of monosomy 7 syndrome in a child with NF in the United States, and that this case complements a recent report of two cases of NF, JCMMoL, and monosomy 7 in Japanese children. Since monosomy 7 syndrome is very difficult to differentiate from JCMMoL or acute nonlymphocytic leukemia (ANLL) unless appropriate chromosomal studies are obtained, we believe it is possible that monosomy 7 may occur with increased frequency in patients with NF-1. Monosomy 7 syndrome might therefore be a significant cause of the known association between NF-1 and nonlymphoid leukemia.     

Intensive short course chemotherapy for tuberculous meningitis.

This nonrandomized, open clinical investigation of tuberculous meningitis evaluated 53 children with Stage I (n = 8), Stage II (n = 29) and Stage III (n = 16) disease. The overall mortality was 20.8% (11 of 53) with a rate of sequelae of 35.7% (15 of 42) in survivors reflecting the advanced stages of children at diagnosis. Various combinations of standard antituberculous drugs including isoniazid, rifampin, pyrazinamide, streptomycin and ethambutol were given. Three treatment durations used during various time periods were evaluated: 12, 9 and 6 months with only the 6-month regimen receiving pyrazinamide (PZA). This prospective evaluation demonstrated that: (1) severe disease at presentation is highly associated with early mortality (P less than 0.05), regardless of drug regimen; and (2) intensive short course chemotherapy (6 months) with PZA, regardless of stage of disease at presentation, is more efficacious than longer course therapy (9 or 12 months) without PZA in preventing total negative outcomes and sequelae (P less than 0.05). This study demonstrates that a 6-month regimen containing PZA can be used in treating children with tuberculous meningitis.     

The influence of long-term cimetidine as an adjuvant to pancreatic enzyme therapy in cystic fibrosis

Seventeen patients on constant doses of pancreatic enzymes were randomised to receive either cimetidine or placebo for either of two successive six month periods. Nutritional state and maldigestion were assessed at the beginning and end of each period. Reductions in mean values of faecal fat, nitrogen, wet weight, and bile salts of approximately 30% were found on cimetidine therapy. Results showed considerable variation and only the fall in faecal fat was statistically significant. No benefit was demonstrated for height, weight, skinfold thickness, albumin, vitamin A, bone age or Crispin-Norman score.

Intussusception: influence of age on reducibility

Our experience of hydrostatic reduction of intussusception by barium enema over the last 7 years is reviewed. There were 115 attempted hydrostatic reductions out of a total of 129 patients diagnosed as having intussusception on barium enema or at surgery. Age at presentation varied from one month to nine years, 81% of patients presenting before one year of age. Of 115 attempted reductions, 63 were successful giving an overall success rate of 55%. Looking at the different age groups, it was found that hydrostatic reduction was much less successful in infants aged 3 months and younger; success rate 20% compared to a 60% success rate in the remainder. Conscious of recent reports in the literature of bowel perforation during attempted hydrostatic reduction in young infants, we suggest that there should be a reappraisal of the role of hydrostatic reduction in the three months and younger age group.
