Socioeconomic Status and Psychological Function in Children with Chromosome 22q11.2 Deletion Syndrome: Implications for Genetic Counseling

The purpose of this study is to examine the association between parental socio-economic status (SES) and childhood neurocognition and behavior in children with chromosome 22q11.2 deletion syndrome (22q11DS). Although undoubtedly, the deletion of genes in the 22q11.2 interval is primarily responsible for the psychological manifestations, little is known about the role of the environment in either mitigating or contributing to these problems. We examined the association of parental socio-economic status (SES) with cognition and behavior in children with 22q11DS (n = 65) and matched healthy control subjects (n = 52), since SES is a component of family resources. We found that in children with 22q11DS, higher SES correlated with better overall functioning (p < .01) and social skills (p < .01), and less frequent oppositional defiant behavior (p < .001). These findings were in contrast to the control subjects in whom SES correlated with cognition and achievement, but not behavior. Our results indicate that environmental factors influence the behavioral phenotype in children with 22q11DS, providing a framework for developing appropriate interventions. As such, genetic counseling for families with 22q11DS may include consideration of family resources and inclusion of other health professionals, such as social workers, to explore with the family available social supports and resources.     

Ceftriaxone rescues hippocampal neurons from excitotoxicity and enhances memory retrieval in chronic hypobaric hypoxia

Exposure to high altitude is known to cause impairment in cognitive functions in sojourners. The molecular events leading to this behavioral manifestation, however, still remain an enigma. The present study aims at exploring the nature of memory impairment occurring on chronic exposure to hypobaric hypoxia and the possible role of glutamate in mediating it. Increased ionotropic receptor stimulation by glutamate under hypobaric hypoxic conditions could lead to calcium mediated excitotoxic cell death resulting in impaired cognitive functions. Since glutamate is cleared from the synapse by the Glial Glutamate Transporter, upregulation of the transporter can be a good strategy in preventing excitotoxic cell death. Considering previous reports on upregulation of the expression of Glial Glutamate Transporter on ceftriaxone administration, the therapeutic potential of ceftriaxone in ameliorating hypobaric hypoxia induced memory impairment was investigated in male Sprague Dawley rats. Exposure to hypobaric hypoxia equivalent to an altitude of 7600 m for 14 days lead to oxidative stress, chromatin condensation and neuronal degeneration in the hippocampus. This was accompanied by delayed memory retrieval as evident from increased latency and pathlength in Morris Water Maze. Administration of ceftriaxone at a dose of 200 mg/kg for 7 days and 14 days during the exposure on the other hand improved the performance of rats in the water maze along with decreased oxidative stress and enhanced neuronal survival when compared to hypoxic group without drug administration. An increased expression of Glial Glutamate Transporter was also observed following drug administration indicating faster clearance of glutamate from the synapse. The present study not only brings to light the effect of longer duration of exposure to hypobaric hypoxia on the memory functions, but also indicates the pivotal role played by glutamate in mediating excitotoxic neuronal degeneration at high altitude. The therapeutic potential of ceftriaxone in providing neuroprotection in excitotoxic conditions by increasing Glial Glutamate Transporter expression and thereby enhancing glutamate uptake from the synapse has also been explored.     

LOEVINGER'S SENTENCE COMPLETION TEST OF EGO DEVELOPMENT: A USEFUL TOOL FOR CROSS-CULTURAL RESEARCHERS

This study examined the validity of Loevinger's ego development model and method from a cross-cultural perspective. Loevinger's Sentence Completion Test was administered to 171 Australian and 110 Indian tertiary students. The results strongly supported Loevinger's claims for the universality of her model.     

An empirical investigation of Garnets and Pleck's Sex Role Strain Analysis

This study is an empirical investigation of Garnets and Pleck's conceptual analysis — the Sex Role Strain Analysis — which sought to explain the contradictory findings in regard to the relationship between sex role identity and self-esteem. Garnets and Pleck (Sex Role Identity, Androgyny, and Sex Role Transcendence: A Sex Role Strain Analysis, Psychology of Women, 1979, 3(3), 270–283) argued that, while much of previous research assumed that sex role identity has a direct effect on self-esteem, the relationship between the two is actually moderated by the same-sex ideal and sex role salience. This paper adapted the model by considering the effect of sex role salience at the individual and at the cultural levels. More specifically, the revised model was tested within two societies (India and Australia) that differ markedly in the level of sex role salience at the cultural level. The results revealed that sex role salience at the cultural level is an important moderating variable. In the Indian sample, for example, the relationship between sex role ientity and self-esteem is moderated by individual's perception of the sam-sex ideal. In societies (e.g., Australia) that emphasize individuality, however, the relationship between sex role identity and self-esteem is probably moderated by other variables such as individuals' perception of the image that they desire for themselves. The implications of these findings for sex role identity research are discussed.     

Implicit memory for phonological processes in visual stem completion

Four experiments were conducted investigating the role of phonology in repetition priming. Experiment 1 used a cross-modal priming paradigm in which participants made semantic judgments about spoken words and then performed a visual stem completion task. In Experiments 2–4, both the primes and the test stems were presented visually. The results of the first three experiments revealed that priming transfers across interpretations of a homophone. That is, seeing or hearingweek primes bothweek andweak. The results of Experiment 4 showed that homophone priming cannot be attributed to the orthographic similarity of homophonic words. Together, these results indicate that repetition priming on a visual word completion task includes a phonological component.     

Psychopathology in Children with Thalassemia Major

The present work investigated the prevalence and spectrum of psychopathology in children with thalassemia. Childhood psychopathology measurement schedule (CPMS), adapted from Child Behavior Checklist was administered on children with thalassemia major receiving regular blood transfusion. Age and sex matched children with other chronic illness (bronchial asthma) served as controls. 46.7% of children with thalassemia had a CPMS score of > 10 as against 17.1% in the control group. Children with thalassemia had higher scores in factors of conduct problems, special symptoms and somatization. This study highlights the significantly higher psychopathology in children with thalassemia major and emphasizes the need for psychosocial support during treatment.     

Consciousness as an Inhibited Manifestation and Quantum Physics

The term soul is used in the traditional literature as a synonym for one’s true Self and is associated with the subjective essence of one’s living. Since, we don’t have any means to quantify it, the science has ruled out this idea from its investigations. But, in a recent study, Ceylan et al. (2017) has reintroduced the word soul to scientific literature and examined the possibility of the study of the soul through scientific modalities. The primary focus of their study is to find and understand the scientific analog of the soul as quoted and discussed in the traditional literature. In the present paper, we examine the idea of a soul that uses a novel approach; integrating neuroscience and quantum physics, as proposed in Ceylan et al. (2017). For this purpose, we make use of findings from neuroscientific studies on meditation to understand the concepts of soul and consciousness in terms of inhibition mechanisms. In this context, this paper serves as an attempt to call for more studies to discuss and expand the hypothesis about the soul as uninhibited mental activity.     

Not the End of the Odyssey: Parental Perceptions of Whole Exome Sequencing (WES) in Pediatric Undiagnosed Disorders

Due to the lack of empirical information on parental perceptions of primary results of whole exome sequencing (WES), we conducted a retrospective semi-structured interview with 19 parents of children who had undergone WES. Perceptions explored during the interview included factors that would contribute to parental empowerment such as: parental expectations, understanding of the WES and results, utilization of the WES information, and communication of findings to health/educational professionals and family members. Results of the WES had previously been communicated to families within a novel framework of clinical diagnostic categories: 5/19 had Definite diagnoses, 6/19 had Likely diagnoses, 3/19 had Possible diagnosis and 5/19 had No diagnosis. All parents interviewed expressed a sense of duty to pursue the WES in search of a diagnosis; however, their expectations were tempered by previous experiences with negative genetic testing results. Approximately half the parents worried that a primary diagnosis that would be lethal might be identified; however, the hope of a diagnosis outweighed this concern. Parents were accurately able to summarize their child’s WES findings, understood the implications for recurrence risks, and were able to communicate these findings to family and medical/educational providers. The majority of those with a Definite/Likely diagnosis felt that their child’s medical care was more focused, or there was a reduction in worry, despite the lack of a specific treatment. Irrespective of diagnostic outcome, parents recommended that follow-up visits be built into the process. Several parents expressed a desire to have all variants of unknown significance (VUS) reported to them so that they could investigate these themselves. Finally, for some families whose children had a Definite/Likely diagnosis, there was remaining frustration and a sense of isolation, due to the limited information that was available about the diagnosed rare disorders and the inability to connect to other families, suggesting that for families with rare genetic disorders, the diagnostic odyssey does not necessarily end with a diagnosis. Qualitative interviewing served a meaningful role in eliciting new information about parental motivations, expectations, and knowledge of WES. Our findings highlight a need for continued communication with families as we navigate the new landscape of genomic sequencing.
