Clinical Hypnosis as an Adjunct to Cognitive Behavior Therapy: An Updated Meta-Analysis.

In 1995, Kirsch and colleagues published an influential meta-analysis (k = 20, N = 577) which found that CBT enhanced with hypnosis (CBTH) was superior to CBT alone by at least d = .53. However, a lack of full replication and the emergence of new empirical studies prompted this updated analysis. A total of 48 post- (N = 1,928) and 25 follow-up treatments (N = 1,165) were meta-analyzed. CBTH achieved small to medium but statistically significant advantages over CBT at posttreatment (dIGPP/d = .25 to .41), and specifically in the management of depressed mood and pain. At follow-up, there was a medium sized advantage for CBTH (dIGPP/d = .54 to .59), and specifically for the treatment of obesity. These results further support the adjunctive use of hypnosis as an enhancer of CBT's efficaciousness and endurance as a treatment.

Antiapoptotic serine protease inhibitors contribute to survival of allergenic TH2 cells.

BACKGROUND: The mechanisms that regulate maintenance of persistent TH2 cells and potentiate allergic inflammation are not well understood. OBJECTIVE: The function of serine protease inhibitor 2A (Spi2A) was studied in mouse TH2 cells, and the serine protease inhibitor B3 (SERPINB3) and SERPINB4 genes were studied in TH2 cells from patients with grass pollen allergy. METHODS: Spi2A-deficient TH2 cells were studied in in vitro culture or in vivo after challenge of Spi2A knockout mice with ovalbumin in alum. Expression of SERPINB3 and SERPINB4 mRNA was measured in in vitro-cultured TH2 cells and in ex vivo CD27-CD4+ cells and innate lymphoid cell (ILC) 2 from patients with grass pollen allergy by using quantitative PCR. SERPINB3 and SERPINB4 mRNA levels were knocked down in cultured CD27-CD4+ cells with small hairpin RNA. RESULTS: There were lower levels of in vitro-polarized TH2 cells from Spi2A knockout mice (P < .005) and in vivo after ovalbumin challenge (P < .05), higher levels of apoptosis (Annexin V positivity, P < .005), and less lung allergic inflammation (number of lung eosinophils, P < .005). In vitro-polarized TH2 cells from patients with grass pollen allergy expressed higher levels of both SERPINB3 and SERPINB4 mRNA (both P < .05) compared with unpolarized CD4 T cells. CD27-CD4+ from patients with grass pollen allergy expressed higher levels of both SERPINB3 and SERPINB4 mRNA (both P < .0005) compared with CD27+CD4+ cells. ILC2 expressed higher levels of both SERPINB3 and SERPINB4 mRNA (both P < .0005) compared with ILC1. Knockdown of either SERPINB3 or SERPINB4 mRNA (both P < .005) levels resulted in decreased viability of CD27-CD4+ compared with control transduced cells. CONCLUSION: The Serpins Spi2A in mice and SERPINB3 and SERPINB4 in allergic patients control the viability of TH2 cells. This provides proof of principle for a therapeutic approach for allergic disease through ablation of allergic memory TH2 cells through SERPINB3 and SERPINB4 mRNA downregulation.

Low dietary intake of magnesium is associated with increased externalising behaviours in adolescents.

OBJECTIVE: Adequate Zn and Mg intakes may be beneficial for the prevention and treatment of mental health problems, such as depression, anxiety and attention-deficit hyperactivity disorder. We aimed to investigate the prospective association between dietary intakes of Zn and Mg and internalising and externalising behaviour problems in a population-based cohort of adolescents. DESIGN: Prospective analysis (general linear mixed models) of dietary intakes of Zn and Mg assessed using a validated FFQ and mental health symptoms assessed using the Youth Self-Report (YSR), adjusting for sex, physical activity, family income, supplement status, dietary misreporting, BMI, family functioning and energy intake. SETTING: Western Australian Pregnancy Cohort (Raine) Study. SUBJECTS: Adolescents (n 684) at the 14- and 17-year follow-ups. RESULTS: Higher dietary intake of Mg (per SD increase) was significantly associated with reduced externalising behaviours (ß = -1.45; 95% CI -2.40, -0.50; P = 0.003). There was a trend towards reduced externalising behaviours with higher Zn intake (per SD increase; ß = -0.73; 95% CI -1.57, 0.10; P = 0.085). CONCLUSIONS: The study shows an association between higher dietary Mg intake and reduced externalising behaviour problems in adolescents. We observed a similar trend, although not statistically significant, for Zn intake. Randomised controlled trials are necessary to determine any benefit of micronutrient supplementation in the prevention and treatment of mental health problems in adolescents.

Low vitamin D levels are associated with symptoms of depression in young adult males.

OBJECTIVE: Results from studies examining associations between serum 25-hydroxyvitamin D (25(OH)D) concentrations and depressive symptoms are equivocal. We investigated the relationship between serum 25(OH)D concentrations and symptoms of depression, anxiety and stress in a cross-sectional analysis of a population-based sample of young adults participating in the Western Australian Pregnancy Cohort (Raine) Study. METHODS: Participants provided a blood sample at the 20-year follow-up (March 2010-April 2012) for the measurement of serum 25(OH)D concentrations. Mental health symptoms were assessed using the 21-item Depression Anxiety Stress Scales (DASS-21). Associations between serum 25(OH)D concentrations and total DASS-21 scores and subscale scores of depression, anxiety and stress were explored in males and females using negative binomial regression, adjusting for age, race, body mass index (BMI) and physical activity (n=735). Models examining subscale scores were also adjusted for the other subscale scores. RESULTS: After adjusting for confounders, an increase in serum 25(OH)D concentrations of 10 nmol/L decreased total DASS-21 scores in males by 9% (rate ratio (RR) 0.91; 95%CI 0.87,0.95; p<0.001) and depression subscale scores in males by 8% (RR 0.92; 95%CI 0.87,0.96; p=0.001). However, in adjusted models there were no significant associations between serum 25(OH)D concentrations and symptoms of anxiety and stress in males. There were no significant associations between serum 25(OH)D concentrations and symptoms of depression, anxiety and stress in females. CONCLUSIONS: We found an association between serum 25(OH)D concentrations and symptoms of depression, but not anxiety and stress, in males. Randomised controlled trials are necessary to determine any benefit of vitamin D supplementation in the prevention and treatment of depressive symptoms in young adults.

A review of interferon use in patients with relapsing remitting multiple sclerosis in the Canterbury region, New Zealand: 2000-2006.

We report a retrospective medical chart review of 104 patients resident in Canterbury and surrounding districts with relapsing remitting multiple sclerosis (RRMS), who received funded interferon-beta between 2000 and 2006. The aim of the study was to review relapse rates, Expanded disability status scale (EDSS) scores and intravenous methylprednisolone (IVMP) use in the 2-year period before, and following, the initiation of interferon-beta therapy. Demographic analysis showed that the age at entry, duration of disease and EDSS at entry were each greater than in the landmark clinical trials. Relapse rates and usage of IVMP decreased when compared to the 2 years prior to treatment.
