Maternal attachment influences mother–infant styles of regulation and play with objects at nine months

We examined the association between the quality of maternal representations of attachment evaluated by the Adult Attachment Interview (AAI) and mother styles of regulating attention and emotion during free play with objects in 41 mother dyads when infants were nine months old. The secure mother dyads showed a greater duration of engagement matches, with more positive matches, and a greater capacity to move from non-matched to matched states. Secure mother dyads demonstrated greater involvement in play with objects than insecure mother dyads. Insecure mother dyads showed a greater duration of mismatches and spent more time in negative matches. Correlations between maternal AAI scores and the variables studied also showed that the maternal Passivity and Unresolved scales were associated with less adequate dyadic attention and emotion regulation, while the maternal Coherence scale was associated with more adequate dyadic attention and emotion regulation.     

Modifying and validating the Composite International Diagnostic Interview (CIDI) for use in Nepal

Background: Efforts to develop and validate fully‐structured diagnostic interviews of mental disorders in non‐Western countries have been largely unsuccessful. However, the principled methods of translation, harmonization, and calibration that have been developed by cross‐national survey methodologists have never before been used to guide such development efforts. The current report presents the results of a rigorous program of research using these methods designed to modify and validate the Composite International Diagnostic Interview (CIDI) for an epidemiological survey in Nepal. Methods: A five‐step process of translation, harmonization, and calibration was used to modify the instrument. A blinded clinical reappraisal design was used to validate the instrument. Results: Preliminary interviews with local mental health expert led to a focus on major depressive episode, mania/hypomania, panic disorder, post‐traumatic stress disorder, generalized anxiety disorder, and intermittent explosive disorder. After an iterative process of multiple translations‐revisions guided by the principles developed by cross‐national survey methodologists, lifetime DSM‐IV diagnoses based on the final Nepali CIDI had excellent concordance with diagnoses based on blinded Structured Clinical Interview for DSM‐IV (SCID) clinical reappraisal interviews. Conclusions: Valid assessment of mental disorders can be achieved with fully‐structured diagnostic interviews even in low‐income non‐Western settings with rigorous implementation of replicable developmental strategies.

A Panel Interview on the Ethical Practice of Neuropsychology

Neuropsychologists who have considerable experience reflecting, presenting, publishing, and advising on ethical matters are a rich resource for clinicians who have ethics questions. Consultation with such colleagues can be an important part of the ethical decision-making process. The purpose of the present article is to provide the opinions and perspectives of three neuropsychologists who, based on their experience and scholarly activities, served as panelists regarding ethical matters. Although the advice and opinions of colleagues are not a substitute for familiarity with relevant ethical requirements, guidelines, and professional literature, they offer valuable information that enhances the ethical decision-making process.     

Serotonin transporter gene polymorphisms and treatment-resistant depression

Major Depression Disorder (MDD) is a serious mental illness that is one of the most disabling diseases worldwide. In addition, approximately 15% of depression patients are defined treatment-resistant (TRD). Preclinical and genetic studies show that serotonin modulation dysfunction exists in patients with TRD. Some polymorphisms in the promoter region of the serotonin transporter gene (SLC6A4) are likely to be involved in the pathogenesis/treatment of MDD; however, no data are available concerning TRD.     

Neurotrophin-3 gene,intelligence, and selective attention deficit in a Korean sample with attention-deficit/hyperactivity disorder

Objective

Attention-deficit/hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder with a strong genetic component. Neurotrophin-3 (NTF3), which participates in the differentiation and survival of dopaminergic and noradrenergic neurons, has been identified as a factor in the development of ADHD. We investigated the relationships between ADHD and NTF3 gene polymorphism.

Methods

We conducted a case–control analysis of 202 ADHD subjects and 159 controls, performed a transmission disequilibrium test (TDT) on 151 trios, and compared the intelligence quotient (IQ) and a continuous performance test (CPT) according to the genotype of two single-nucleotide polymorphisms (SNPs) (rs6332 and rs6489630) in the NTF3 gene.

Results

In the case–control and family-based analyses, NTF3 was not significantly associated with ADHD. However, in the ADHD probands, the subjects with AA genotype in the rs6332 SNP had significantly higher mean T-scores for commission errors on the CPT than did those with the AG genotypes (p = 0.045). The mean IQ of the ADHD probands who had the CC genotype of the rs6489630 SNP were higher compared with those who had the CT or TT genotype (p = 0.035). The mean T-score for response time on the CPT was higher in the subjects with TT genotype in the rs6489630 SNP compared to those with the CC or CT genotype, even after adjusting for the effect of IQ (p = 0.021).

Conclusions

These results provide preliminary evidence of an association between NTF3 and the intelligence and selective attention deficit in the Korean population.     

Exploring the relationship between cognitive illness representations and poor emotional health and their combined association with diabetes self-care. A systematic review with meta-analysis

Objective

Depression and anxiety are common in diabetes and are associated with lower diabetes self-care adherence. How this occurs is unclear. Our systematic review explored the relationship between cognitive illness representations and poor emotional health and their combined association with diabetes self-care.

Methods

Medline, Psycinfo, EMBASE, and CINAHL were searched from inception to June 2013. Data on associations between cognitive illness representations, poor emotional health, and diabetes self-care were extracted. Random effects meta-analysis was used to test the relationship between cognitive illness representations and poor emotional health. Their combined effect on diabetes self-care was narratively evaluated.

Results

Nine cross-sectional studies were included. Increased timeline cyclical, consequences, and seriousness beliefs were associated with poorer emotional health symptoms. Lower perceived personal control was associated with increased depression and anxiety, but not mixed anxiety and depressive symptoms. Remaining cognitive illness representation domains had mixed statistically significant and non-significant relationships across emotional states or were measured only once. Effect sizes ranged from small to large (r = ± 0.20 to 0.51). Two studies explored the combined effects of cognitions and emotions on diabetes self-care. Both showed that cognitive illness representations have an independent effect on diabetes self-care, but only one study found that depression has an independent effect also.

Conclusions

Associations between cognitive illness representations and poor emotional health were in the expected direction — negative diabetes perceptions were associated with poorer emotional health. Few studies examined the relative effects of cognitions and emotions on diabetes self-care. Longitudinal studies are needed to clarify directional pathways.     

Does α-synuclein have a dual and opposing effect in preclinical vs. clinical Parkinson's disease?

α-Synuclein gene (SNCA) multiplications cause familial parkinsonism and allele-length polymorphisms within the SNCA dinucleotide repeat REP1 increase the risk for developing Parkinson's disease (PD). Since SNCA multiplications increase SNCA expression, and REP1 genotypes that increase the risk of developing PD show increased SNCA expression in cell-culture systems, animal models, and human blood and brain, PD therapies seek to reduce SNCA expression. We conducted an observational study of 1098 PD cases to test the hypothesis that REP1 genotypes correlated with reduced SNCA expression are associated with better motor and cognitive outcomes. We evaluated the association of REP1 genotypes with survival free of Hoehn and Yahr stages 4 or 5 (motor outcome) and of Modified Telephone Interview for Cognitive Status score ≤27 or Alzheimer's Disease Dementia Screening Interview score ≥2 (cognitive outcome). Median disease duration at baseline was 3.3 years and median lag time from baseline to follow-up was 7.8 years. Paradoxically, REP1 genotypes associated with increased risk of developing PD and increased SNCA expression were associated with better motor (HR = 0.87, p = 0.046, covariate-adjusted age-scale analysis; HR = 0.85, p = 0.020, covariate-adjusted time-scale analysis) and cognitive outcomes (HR = 0.90, p = 0.12, covariate-adjusted age-scale analysis; HR = 0.85, p = 0.023, covariate-adjusted time-scale analysis). Our findings raise the possibility that SNCA has a dual, opposing, and time-dependent role. This may have implications for the development of therapies that target SNCA expression.

A comparative study of caregivers’ perceptions of health-care needs and burden of patients with bipolar affective disorder and schizophrenia

Abstract

Background: Although many studies in schizophrenia have evaluated health-care needs, there is a lack of data on the needs of patients with bipolar affective disorder (BPAD), with only occasional studies evaluating them, and no study has evaluated the relationship of health-care needs of patients with caregiver's burden. Aim: To study the relationship of caregiver's burden and needs of patients as perceived by caregivers of patients with BPAD and schizophrenia. Method: Caregivers of patients with BPAD and schizophrenia were assessed using the Camberwell Assessment of Needs – Research version (CAN-R) and Supplementary Needs Assessment Scale (SNAS), the Family Burden Interview schedule (FBI) and the Involvement Evaluation Questionnaire (IEQ). Results: Mean total needs of patients on CAN-R were 7.54 (SD 3.59) and 7.58 (SD 4.24) for BPAD and schizophrenia respectively. Mean total needs for SNAS were 7.24 (SD 3.67) and 7.68 (SD 5.02) for BPAD and schizophrenia groups, respectively. Total objective and subjective burden as assessed on FBI was significantly more for the schizophrenia group. Caregivers of patients with BPAD perceived significantly less disruption of routine family activities and lower impact on the mental health of others. On IEQ, the mean score on the domain of supervision was significantly higher for the BPAD group. In the schizophrenia group, positive correlations were seen between the total number of unmet and total (met and unmet) needs and certain aspects of burden, but no such correlations emerged in the BPAD group. Conclusion: There is no correlation between number of needs and burden in the BPAD group; however, in the schizophrenia group the number of needs correlated with the perceived burden. Accordingly, orienting services to address needs of patients with schizophrenia can lead to reduction in burden among caregivers.
