Alexithymia and Breast Cancer Surgery: A Systematic Review

The term alexithymia is a complex multidimensional construct that literally means “no words for mood”. There are two kind of alexithymia: primary and secondary or otherwise called trait and state alexithymia. There is still an unresolved debate about the nature of alexithymia as a trait or a state. The etiology of alexithymia has not been completely determined because of the numerous factors influencing its development. Alexithymia has been observed among patients with a variety of psychiatric disorders and medical conditions. The aim of this systematic review was to review studies investigating the correlations between alexithymia, depression and anxiety in breast cancer surgery women. Literature search was conducted in January, 2016. PubMed and Scopus databases were used to find studies for inclusion in the systematic review. Correlations between alexithymia, depression and anxiety evidenced that alexithymia may be considered a stable personality trait and an important factor to the development of anxiety symptoms. However, limitations of these studies must be considered and further investigations are needed.

Physical Activity as a Buffer for Anxiety Symptoms in Rural African American Adolescent Females

The study examines how physical activity buffers the development of anxiety symptoms in response to racerelated stress and negative youth experiences. The participants are 72 adolescent females from an understudied population of rural African American students residing in South Central Louisiana. Recent literature suggests that physical fitness increases one’s ability to cope with psychological stress and may prevent or combat anxiety disorders. However, American adolescents are becoming less physically active, particularly African American females. Previous literature shows that adolescent females report higher levels of mental health challenges than their male counterparts. The results indicate that physical activity is an effective buffer against increased anxiety symptomology. In addition, the results present this population as resilient rather than “at risk” for developing vulnerability to mental health challenges.

Rough-and-Tumble Play and Other Parental Factors as Correlates of Anxiety Symptoms in Preschool Children

The present study investigated the relationship between parental rough-and-tumble (R&T) play and young children’s anxiety symptoms. Parents of 105 non-clinical children (61 boys and 44 girls aged between 2 and 6 years) completed indices of childhood anxiety symptoms and parental trait anxiety and overprotection, as well as the Parental Play and Care Questionnaire, which was developed for the purpose of this study to assess parental R&T play and care activities. Results showed that fathers exhibited more R&T play towards their offspring, while mothers more often engaged in care activities. As predicted, trait anxiety and overprotection of mothers were positively related to child anxiety symptoms. No support was found for the idea that parental R&T play would be negatively related to childhood anxiety. However, an interaction effect of fathers’ trait anxiety and R&T play on anxiety symptoms of the child was found: children tended to display higher levels of anxiety symptoms when their low trait anxious fathers were more involved in R&T play. The results provide support for the notion that mothers and fathers have unique parenting roles, which may have a differential impact on the development of anxiety symptoms in children.

The Course of Childhood Anxiety Symptoms: Developmental Trajectories and Child-Related Factors in Normal Children

This three-wave longitudinal study explored developmental trajectories for various types of childhood anxiety symptoms (i.e., specific fears, social anxiety, generalized anxiety, and separation anxiety) and examined how these trajectories were associated with several factors thought to be involved in the pathogenesis of anxiety. Parents of a community sample of 224 children aged 4 to 11 years repeatedly completed a standardized questionnaire of anxiety symptoms during a 2-year period. At Time 1, parents also filled out scales for measuring children's level of behavioral inhibition (BI), internalizing and externalizing symptoms, and prosocial behaviors, while an interview was conducted with children to assess Theory-of-Mind (TOM) ability. Growth Mixture Modeling identified multiple developmental trajectories in childhood anxiety symptoms of which the 'stable-low' or 'stable-medium' reflected the normative trajectories. Further, multinomial regression analyses indicated that the higher developmental trajectories of anxiety were associated with higher levels of BI and internalizing symptoms at Time 1. In sum, results show heterogeneity in the development of anxiety symptoms and underline the importance of early prevention programs for children at high risk for developing an anxiety disorder.

Hyperventilation in men claiming compensation for benign asbestos-related diseases

The observation that hyperventilation was common in men involved in civil court actions compared with my non-medico-legal practice stimulated me to carefully assess 100 consecutively seen men with non-malignant asbestos-related disease(s). A diagnosis of hyperventilation was made in 33 and probable hyperventilation in 12. The development of anxiety symptoms in these men could, in part at least, be prevented or greatly decreased if more emphasis was placed on the education of ex-asbestos workers by solicitors and organisations responsible for the initiation of civil actions.

Behavioral Inhibition as a Risk Factor for the Development of Childhood Anxiety Disorders: A Longitudinal Study

This longitudinal study examined the additive and interactive effects of behavioral inhibition and a wide range of other vulnerability factors in the development of anxiety problems in youths. A sample of 261 children, aged 5 to 8 years, 124 behaviorally inhibited and 137 control children, were followed during a 3-year period. Assessments took place on three occasions to measure children’s level of behavioral inhibition, anxiety disorder symptoms, other psychopathological symptoms, and a number of other vulnerability factors such as insecure attachment, negative parenting styles, adverse life events, and parental anxiety. Results obtained with Structural Equation Modeling indicated that behavioral inhibition primarily acted as a specific risk factor for the development of social anxiety symptoms. Furthermore, the longitudinal model showed additive as well as interactive effects for various vulnerability factors on the development of anxiety symptoms. That is, main effects of anxious rearing and parental trait anxiety were found, whereas behavioral inhibition and attachment had an interactive effect on anxiety symptomatology. Moreover, behavioral inhibition itself was also influenced by some of the vulnerability factors. These results provide support for dynamic, multifactorial models for the etiology of child anxiety problems.

Developmental trajectories of anxiety symptoms among boys across early and middle childhood.

This study examined the developmental trajectory of anxiety symptoms among 290 boys and evaluated the association of trajectory groups with child and family risk factors and children's internalizing disorders. Anxiety symptoms were measured using maternal reports from the Child Behavior Checklist (T. M. Achenbach, 1991, 1992) for boys between the ages of 2 and 10. A group-based trajectory analysis revealed 4 distinct trajectories in the development of anxiety symptoms: low, low increasing, high declining, and high-increasing trajectories. Child shy temperament tended to differentiate between initial high and low groups, whereas maternal negative control and maternal depression were associated with increasing trajectories and elevated anxiety symptoms in middle childhood. Follow-up analyses to diagnoses of preadolescent depression and/or anxiety disorders revealed different patterns on the basis of trajectory group membership. The results are discussed in terms of the mechanisms of risk factors and implications for early identification and prevention.

A Multifactorial Model for the Etiology of Anxiety in Non-Clinical Adolescents: Main and Interactive Effects of Behavioral Inhibition, Attachment and Parental Rearing

There has been limited research examining the additive and interactive effects of multiple factors on the development of anxiety symptoms and anxiety disorders in youths. This study was an attempt to examine the reciprocal connections among temperament, attachment, and rearing style, and their unique and interactive relations to anxiety symptoms. Six hundred forty-four non-clinical children aged 11–15 years (mean age = 12.7 years) completed questionnaires measuring behavioral inhibition, attachment, parental rearing behavior, and anxiety symptoms. Results indicated that there were small to moderate positive correlations among various risk factors. Furthermore, modest but significant positive correlations were found between behavioral inhibition, attachment quality, and anxious and controlling rearing behaviors on the one hand, and anxiety scores on the other hand. That is, higher levels of behavioral inhibition, insecure attachment, and parental control and anxious rearing were associated with higher levels of anxiety symptoms. Finally, behavioral inhibition, attachment quality, parental control and anxious rearing each accounted for a small but unique proportion of the variance of anxiety disorders symptomatology. Little support was found for interactive effects of these vulnerability factors on childhood anxiety.

Information-processing predictors of emotional response to stress

Information-processing biases of attention toward and interpretation of threat were measured in 29 undergraduates during a period of low academic stress. During a later period of high academic stress, participants were interviewed about their emotional response: anxious and depressive symptoms, and positive and negative affect. Anxiety symptoms at follow-up were predicted by attention to masked threat stimuli, while negative affect at follow-up was predicted by interpretation of ambiguous items as threatening. Results suggest that although attentional processes appears to play a role in the development of anxiety symptoms, the experience of negative affect during stress may be regulated by more interpretive processes.

Blood Lactate in the Development of Anxiety Symptoms

<h3>Pitts and McClure's Theory and Experiment</h3> RECENTLY Pitts and McClure^1-3claimed to have demonstrated that symptoms of anxiety neurosis are caused by lactate ion, or more specifically, by the effect which excess of lactate ion has on ionized calcium in anxiety-prone subjects. Prompted by the finding that exercise tends to produce an excessive amount of lactic acid in patients with anxiety neurosis,⁴Pitts and McClure hypothesized that "anxiety symptoms may have a common determining biochemical end mechanism involving the complexing of ionized calcium at the surface of excitable membranes"²by lactate. They reasoned that lactate ion accumulates in excessive amounts, more than the normal percentage of ionized calcium becomes complexed with lactate. When the remaining free ionized calcium becomes reduced to clinically significant low concentrations, there will be interference with normal nerve conduction and activity. According to Pitts and McClure,
