Factors Contributing to Posttraumatic Growth Following Bereavement.

Multiple factors have been studied to determine their relationship to posttraumatic growth, with findings suggesting the importance of resiliency (Bensimon, 2012), social support (Tedeschi & Calhoun, 2004), event centrality (Taku et al., 2014), religious coping (Pargament et al., 2006), relationship to the deceased (Oginska-Bulik, 2015), and the circumstance of passing (Feigelman et al., 2009). This study investigated the relationship of these identified factors with posttraumatic growth in a sample of 165 bereaved individuals. Regression results indicated that the overall model predicted scores on posttraumatic growth (R2 = .473, R2 adj = .456, F (5, 159) = 28.51, p < .001), with most robust effects found in social support (ß = .281), religious commitment (ß = .289), and event centrality (ß = .410). This indicates bereavement experiences can result in significant growth in individuals, particularly those who seek social support, identify the event as an essential part of their experience, and identify religion as an important aspect of their routine.

Spiritually incorporating couple therapy in practice: Christian-accommodated couple therapy as an illustration.

Spiritually incorporating couple therapy (SICT)-couple therapy that incorporates spiritual interventions-has a growing research base. Information is limited on how spiritual interventions are used in practice; thus we studied treatment-as-usual (TAU). SICT is treatment that, at a couple's request, sometimes draws upon spiritual resources when addressing relational issues. We tracked 65 couples from 29 couple therapists (who advertised as spiritually incorporating therapists) over 402 sessions of SICT. Couple spirituality predicted use of spiritual interventions more than did therapist spirituality. The most used spiritual interventions included silent prayer for the couple, discussions of hope and forgiveness, and encouragement to consult their heart. In SICT, therapists used evidence-based couple therapy approaches. SICT should (a) treat highly religious couples in high distress as being at risk for early drop out; (b) follow couples' leads in using spiritual methods; and (c) draw on evidence-based couple and spiritual practices.

Forgiveness-reconciliation and communication-conflict-resolution interventions versus retested controls in early married couples.

The first 6 months of marriage are optimal for marriage enrichment interventions. The Hope-Focused Approach to couple enrichment was presented as two 9-hr interventions--(a) Handling Our Problems Effectively (HOPE), which emphasized communication and conflict resolution, and (b) Forgiveness and Reconciliation through Experiencing Empathy (FREE). HOPE and FREE were compared with repeated assessment controls. Couples were randomly assigned and were assessed at pretreatment (t1); 1 month posttreatment (t2) and at 3- (t3), 6- (t4), and 12-month (t5) follow-ups using self-reports. In addition to self-report measures, couples were assessed at t1, t2, and t5 using salivary cortisol, and behavioral coding of decision making. Of 179 couples who began the study, 145 cases were analyzed. Both FREE and HOPE produced lasting positive changes on self-reports. For cortisol reactivity, HOPE and FREE reduced reactivity at t2, but only HOPE at t5. For coded behaviors, control couples deteriorated; FREE and HOPE did not change. Enrichment training was effective regardless of the focus of the training.

Relationship factors and quality among mixed-orientation couples.

Mixed-orientation couples are defined as a heterosexual couple in which 1 partner experiences same-sex attraction and the other does not. Despite the fact that there is a sizable number of mixed-orientation couples in the U.S. adult population, few researchers have studied this population, and thus, there is limited understanding of these relationships. The authors examined the degree to which relationship commitment, partner-focused forgivingness, and marital values were associated with relationship quality, and how these variables predicted relationship quality. The total sample (N = 265) consisted of 2 independent samples-105 sexual minorities (i.e., the spouse who experiences same-sex attraction) and 160 heterosexual spouses. The data were not dyadic. Together, commitment, partner-focused forgivingness, and marital values accounted for roughly 43% of the variance in relationship quality. Relationship commitment was found to be the largest single predictor of relationship quality, followed by partner-focused forgivingness. Research and clinical implications are discussed. This study significantly adds to the current research base by quantitatively measuring various variables in these relationships, as well as expanding our understanding of relationship quality in mixed-orientation couples and factors that may play a role.

Quantification of whole brain arginine vasotocin for two Syngnathus pipefishes: elevated concentrations correlated with paternal brooding.

Arginine vasotocin (AVT) regulates many aspects of fish physiology and behavior including courtship and reproduction. This study begins to address whether paternal functions for AVT have independently evolved in species in which paternal behavior has evolved. We quantified AVT in the brains of Syngnathus fuscus and Syngnathus floridae which, like other pipefishes and seahorses of the family Syngnathidae, brood embryos within specialized structures of the male. For both species, we measured AVT concentrations seventeenfold higher for some males during brooding compared to post-brooding males. Comparable whole brain AVT concentrations between gravid females and males with broods at some embryonic development stages suggest physiological similarities that we hypothesize is related to nutrient provisioning but should be elucidated with further studies including a detailed anatomical analysis of AVT production. Earlier studies have identified differences in the brooding structures of these species. Here we documented interspecific differences in the variability and mean AVT concentration for non-brooding males, the brood stage showing a return to post-brooding concentrations, and the variability of AVT concentrations for brooding males with embryos in some development stages. Future investigations should use these data to investigate the potential for divergent AVT function between species, sexes, and brooding males with embryos of different developmental stages.

Elevated whole brain arginine vasotocin with Aroclor 1254 exposure in two Syngnathus pipefishes.

The neurohypophysial hormone arginine vasotocin (AVT) and the neuroendocrine system strongly interact with the rest of the teleostean endocrine system. The aim of this study is to investigate the effects of exposure to an endocrine disruptor on whole brain AVT concentrations for the pipefishes Syngnathus floridae and S. fuscus. Following treatment over the entire brood period, AVT concentrations were significantly higher for Aroclor 1254-exposed, post-brooding males compared to controls for both species. Considering both previously documented seventeen-fold increases in AVT for brooding males with embryos in some developmental stages and changes in parental nutrient concentrations after Aroclor 1254 exposure, these data begin to address potential physiological mechanisms that may underlie paternal activities in syngnathid males.

Osmoregulatory role of the paternal brood pouch for two Syngnathus species.

Even though sea horses, sea dragons, and pipefishes of the teleost family Syngnathidae have been studied for over a century, the physiological significance of the paternal brood pouch is not well defined. Here we document the regulation of brood pouch osmolality during embryonic development for Syngnathus floridae and Syngnathus fuscus, particularly during the middle brood stages or around hatching. S. fuscus brood pouch osmolality was significantly lower than non-brooding conspecifics for all brood stages, but early and late stage S. floridae displayed pouch osmolality comparable to non-brooding males, suggesting brood pouch osmoregulation at these stages may be important for S. fuscus embryonic development. Quantification of Na(+), K(+), Ca(2+), and Mg(2+) in paternal blood plasma, pouch fluid, and embryos indicated that regulation of these ions contributes to pouch osmoregulation and furthermore, that ions in the brood pouch are most likely derived from the environment and not paternal blood. While both species displayed significant increases in dry mass and changes in embryonic ion concentrations during development, net uptake of paternally-derived ions was not documented. Overall, this examination furthers our understanding of syngnathid brood pouch physiology and offers insight into the evolution of paternal care in these fishes.

Direct evidence for embryonic uptake of paternally-derived nutrients in two pipefishes (Syngnathidae: Syngnathus spp.).

Seahorses, sea dragons and pipefishes of the teleost family Syngnathidae are unique in that embryos develop within specialized brooding structures of the male. We enriched brooding Syngnathus fuscus and Syngnathus floridae males with injections of L-lysine-[(15)N(2)] and 16:0-palmitic acid 1-[(13)C] to demonstrate embryonic uptake of paternally-derived nutrients. While all embryos demonstrated amino acid enrichment, late stages showed significantly higher [(15)N], indicating greater utilization of paternal resources as yolk reserves diminished and embryonic energy demands increased. Limited embryonic [(13)C] uptake, defined as less than 10% of adult enrichment, in 75 and 81% of S. floridae and S. fuscus respectively signified rapid lipid metabolism and thus the need for greater enrichment. Interspecific differences in embryonic uptake of paternally-derived nutrients were not demonstrated. However, interspecific differences in egg nutrient reserves and fry size but comparable fry nutrient levels along with data from a published paternal exposure study indicate paternal transfer in S. fuscus most likely compensates for the comparative egg nutrient deficiency. This study is the first to our knowledge to provide direct evidence for the functional significance of the brood pouch in nutrient provisioning. These results add comparative information on the diversity of Syngnathid paternal care and further our understanding of paternal influence on development.

Utilization of protein expression profiles as indicators of environmental impairment of smallmouth bass (Micropterus dolomieu) from the Shenandoah River, Virginia, USA.

The Shenandoah River (VA, USA), the largest tributary of the Potomac River (MD, USA) and an important source of drinking water, has been the site of extensive fish kills since 2004. Previous investigations indicate environmental stressors may be adversely modulating the immune system of smallmouth bass (Micropterus dolomieu) and other species. Anterior kidney (AK) tissue, the major site of blood cell production in fish, was collected from smallmouth bass at three sites along the Shenandoah River. The tissue was divided for immune function and proteomics analyses. Bactericidal activity and respiratory burst were significantly different between North Fork and mainstem Shenandoah River smallmouth bass, whereas South Fork AK tissue did not significantly differ in either of these measures compared with the other sites. Cytotoxic cell activity was highest among South Fork and lowest among North Fork AK leukocytes. The composite two-dimension gels of the North Fork and mainstem smallmouth bass AK tissues contained 584 and 591 spots, respectively. South Fork smallmouth bass AK expressed only 335 proteins. Nineteen of 50 proteins analyzed by matrix-assisted laser desorption ionization-time of flight were successfully identified. Three of the four identified proteins with increased expression in South Fork AK tissue were involved in metabolism. Seven proteins exclusive to mainstem and North Fork smallmouth bass AK and expressed at comparable abundances serve immune and stress response functions. The proteomics data indicate these fish differ in metabolic capacity of AK tissue and in the ability to produce functional leukocytes. The variable responses of the immune function assays further indicate disruption to the immune system. Our results allow us to hypothesize underlying physiological changes that may relate to fish kills and suggest relevant contaminants known to produce similar physiological disruption.

Influence of estuarine hypoxia on feeding and sound production by two sympatric pipefish species (Syngnathidae).

This research utilizes the acoustic behavior of two sympatric pipefish species to assess the impact of hypoxia on feeding. We collected northern, Syngnathus fuscus, and dusky pipefishes, Syngnathus floridae, from the relatively pristine Chincoteague Bay, Virginia, USA and audiovisually recorded behavior in the laboratory of fish held in normoxic (>5 mg/L O(2)) and hypoxic (2 and 1 mg/L O(2)) conditions. Both species produced high frequency ( approximately 0.9-1.4 kHz), short duration (3-22 msec) clicks. Feeding strikes were significantly correlated with both wet weight of ingested food and click production. Thus, sound production serves as an accurate measure of feeding activity. In hypoxic conditions, reduced food intake corresponded with decreased sound production. Significant declines in both behaviors were evident after 1 day and continued as long as hypoxic conditions were maintained. Interspecific differences in sensitivity were detected. Specifically, S. floridae showed a tendency to perform head snaps at the surface. S. fuscus exhibited a breakdown in the coupling of sound production with food intake in 2 mg/L O(2) with clicks produced in other contexts, particularly choking and food expulsion. Reductions in feeding will ultimately impact growth, health, and eventually reproduction as resources are devoted to survival instead of gamete production and courtship. This work suggests acoustic monitoring of field sites with adverse environmental conditions may reflect changes in feeding behavior in addition to population dispersal.

Differential parental nutrient allocation in two congeneric pipefish species (Syngnathidae: Syngnathus spp.).

Male seahorses and pipefishes of the family Syngnathidae are heralded for their unique brood pouch structures for incubating embryos. There are three general types of brood pouch with increasing complexity: simple ventral gluing, two pouch flaps and a completely sealed sac. The diversity of functional roles within a type in providing nutrition, aeration and protection to offspring is unknown. Here we reveal significant differences in parental nutrient allocation to embryos for two closely related, sympatric pipefishes with similar brood pouch structure. We document differences in embryo attachment, depletion of pouch fluid nutrients over development and egg nutrient partitioning between Syngnathus floridae and Syngnathus fuscus. In S. fuscus, females produce nutritionally poor eggs and the males implant developing embryos in the brood pouch adjacent to blood vessels. A female-biased breeding population was observed, supporting the hypothesis that the cost of male parental care is high in this species. The loose connection between eggs and brood pouch tissues and the appearance of undeveloped eggs and lipid droplets in the pouch of S. floridae males suggest this species utilizes nutrient-rich eggs produced by females as nurse eggs to supplement embryonic development. A balanced sex-ratio for S. floridae further supports more equal parental contribution. This comparison provides evidence of a decline in female gametic investment and reveals the rapid diversification of syngnathid brood pouch function. Our results indicate gross classification of brooding structures into one of the three general pouch types does not predict the energetic investment of males in parental care. But rather, physiological characterization of the relative investment by each sex to offspring is essential to understanding the functional significance of the brood pouch.

Randomized trial of a low-intensity dietary intervention in rural residents: the Rural Physician Cancer Prevention Project.

BACKGROUND: Dietary behavior, specifically a low-fat, high-fiber diet, plays a role in the primary prevention of chronic diseases including cancer. DESIGN: A community-based randomized trial to assess the impact of a low-intensity, physician-endorsed, self-help dietary intervention that provided tailored dietary feedback, and was designed to promote improved fat and fiber behavior in a rural, low-education/low-literacy, partly minority population. The data were collected from 1999 to 2003. SETTING/PARTICIPANTS: A total of 754 patients from three physician practices in rural Virginia completed a baseline telephone survey assessing dietary and psychosocial information, and were then randomly assigned to the intervention or control condition. Follow-up telephone evaluation was based on 522 participants at 1 month, 470 at 6 months, and 516 participants at 12 months. INTERVENTION: A series of tailored feedback, followed by brief telephone counseling and theory-based nutritional education booklets, provided by staggered delivery to the home. MAIN OUTCOME MEASURES: Dietary fat and fiber behavior, dietary intentions to change, self-efficacy for dietary change, and fat and fiber knowledge. RESULTS: The intervention group demonstrated significant improvement in dietary fat and fiber behaviors and intentions to change fat and fiber intake (p <0.05) at 1, 6, and 12 months. CONCLUSIONS: The Rural Physician Cancer Prevention Project provides an effective model for achieving public health-level dietary health behavior changes among a rural, minority, and low-literacy/low-education population.
