Spectral indices of cardiovascular adaptations to short-term simulated microgravity exposure

We investigated the effects of exposure to microgravity on the baseline autonomic balance in cardiovascular regulation using spectral analysis of cardiovascular variables measured during supine rest. Heart rate, arterial pressure, radial flow, thoracic fluid impedance and central venous pressure were recorded from nine volunteers before and after simulated microgravity, produced by 20 hours of 6° head down bedrest plus furosemide. Spectral powers increased after simulated microgravity in the low frequency region (centered at about 0.03 Hz) in arterial pressure, heart rate and radial flow, and decreased in the respiratory frequency region (centered at about 0.25 Hz) in heart rate. Reduced heart rate power in the respiratory frequency region indicates reduced parasympathetic influence on the heart. A concurrent increase in the low frequency power in arterial pressure, heart rate, and radial flow indicates increased sympathetic influence. These results suggest that the baseline autonomic balance in cardiovascular regulation is shifted towards increased sympathetic and decreased parasympathetic influence after exposure to short-term simulated microgravity.     

Rhetorical theory and family therapy practice

The study found that a connection exists between rhetoric and therapy because both fields are interested in using language as a tool for generating change. Persuasion is viewed as inherent in human communication, even though people do not necessarily intentionally attempt to persuade others. Following a brief (but detailed) explanation of the theoretical stance which informs the implementation of rhetorical techniques in therapy, three pragmatic exemplars are offered to demonstrate the employment of two classical rhetorical concepts, the parastasis catalogue and syncrisis.The authors are grateful to Sandra Kodner, MS for her participation in the development of this project.     

Attributions related to wife abuse: A comparison of the perceptions of volunteer advocate-counselors and marriage and family therapists

Attributions related to wife abuse held by advocate-counselors working in women's shelter home settings and marriage and family therapists were compared. The major finding was that the two groups were surprisingly similar in their attributions even though their theoretical backgrounds and training were considerably different. Implications for practice and training are presented.     

The need for developing standardized family pedigree nomenclature

To assess the variation in usage of symbols used in recording a genetic family history, full members of the National Society of Genetic Counselors were surveyed by questionnaire. The questionnaire return rate was 55.3% and genetic counselors from a broad range of clinical experience, genetic counseling training programs and geographic regions responded. There was striking variation in symbols used for recording routine medical information in a genetic family history (i.e., pregnancy, spontaneous abortion, termination of pregnancy). There was even less consensus in recording situations representing new reproductive technologies (i.e., artificial insemination by donor semen, donor ovum, surrogate motherhood). The results of this survey document the need for developing standardized nomenclature in recording genetic family histories as a quality assurance measure in the delivery of genetic services. Such standardization will reduce the chance of incorrect interpretation of patient and family medical and genetic information.     

Attending to the shame: Working with addicted populations

Shame is a potent emotion that plays a major role in the life of addicted individuals. Shame's ability to penetrate and skew major motivational systems may play a part in the formation of addicted lifestyles. The shame-based or shame-prone individual, such as the addicted client, poses unique problems for the therapist. This paper explicates the processes and consequences of shame and offers guidelines to help clinicians work with addicted clients.Mitchell B. Young, MS, is a third-year doctoral student in the department of counseling and development at Purdue University.The author wishes to express appreciation to Kate Kerr, PhD, for her fine editorial work.     

Coparenting and Toddler's Interactive Styles in Family Coalitions

The current study examined the coparenting and toddler's interactive styles in family coalitions. According to structural family theory, boundaries between generations are clear in alliances, but disturbed in coalitions: the parents look to the child to regulate their conflictual relationship and the child attempts to meet this need. In a normative sample studied longitudinally during the Lausanne Trilogue Play situation (LTP, N=38), 15 coalition cases were detected. Styles of coparenting and of child's interactions were determined and compared in coalition and alliance cases at 18 months. Findings confirm the structural family model by showing the specific ways in which the coparenting and the toddler's interactive styles are associated in 3 different patterns of coalitions: binding, detouring, and triangulation. They illustrate how the child's triangular capacity, or her ability to simultaneously communicate with both parents, is used to regulate the parents' relationship. They suggest that the LTP observational paradigm is a promising assessment method of early family interactions. They point to the importance of assessing early the child's contribution to family coalitions.     

Impact of Applied Suicide Intervention Skills Training on the National Suicide Prevention Lifeline

We examined the impact of the implementation of Applied Suicide Intervention Skills Training (ASIST) across the National Suicide Prevention Lifeline's national network of crisis hotlines. Data were derived from 1,507 monitored calls from 1,410 suicidal individuals to 17 Lifeline centers in 2008–2009. Callers were significantly more likely to feel less depressed, less suicidal, less overwhelmed, and more hopeful by the end of calls handled by ASIST‐trained counselors. Few significant changes in ASIST‐trained counselors' interventions emerged; however, improvements in callers' outcomes were linked to ASIST‐related counselor interventions, including exploring reasons for living and informal support contacts. ASIST training did not yield more comprehensive suicide risk assessments.     

Neurocognitive Function and Suicide in U.S. Army Soldiers

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk.
