Development switch in neural circuitry underlying odor-malaise learning

Fetal and infant rats can learn to avoid odors paired with illness before development of brain areas supporting this learning in adults, suggesting an alternate learning circuit. Here we begin to document the transition from the infant to adult neural circuit underlying odor-malaise avoidance learning using LiCl (0.3 M; 1% of body weight, ip) and a 30-min peppermint-odor exposure. Conditioning groups included: Paired odor-LiCl, Paired odor-LiCl-Nursing, LiCl, and odor-saline. Results showed that Paired LiCl-odor conditioning induced a learned odor aversion in postnatal day (PN) 7, 12, and 23 pups. Odor-LiCl Paired Nursing induced a learned odor preference in PN7 and PN12 pups but blocked learning in PN23 pups. 14C 2-deoxyglucose (2-DG) autoradiography indicated enhanced olfactory bulb activity in PN7 and PN12 pups with odor preference and avoidance learning. The odor aversion in weanling aged (PN23) pups resulted in enhanced amygdala activity in Paired odor-LiCl pups, but not if they were nursing. Thus, the neural circuit supporting malaise-induced aversions changes over development, indicating that similar infant and adult-learned behaviors may have distinct neural circuits.     

Social environment and reproduction in female European rabbits (Oryctolagus cuniculus): benefits of the presence of litter sisters

The authors investigated in an observational study the consequences of the presence of litter sisters on the social interactions and on reproductive performance of young female European rabbits (Oryctolagus cuniculus) from a population living under seminatural conditions. In early winter, when all young females were settled in a social group, they were characterized by the presence or absence of litter sisters in their groups. Females with litter sisters in their groups displayed significantly more positive social interaction with females of their social group compared to females without sisters, whereas this difference was mainly due to the high frequency of positive social interactions among the respective sisters. Such differences between the females of both categories were already apparent during the animals' juvenile phase, before the females integrated into a particular group: females which later had litter sisters in their group showed more positive social behavior than females which later no longer had litter sisters. During their first breeding season, females with litter sisters present generally started to breed earlier by an average of 14 days. A more favorable social environment might have possibly facilitated the earlier onset of breeding in females with present litter sisters by attenuating the negative consequences of stress.     

The Influence of Cancer-related Distress and Sense of Coherence on Anxiety and Depression in Patients with Hereditary Cancer

This study examines the association between Sense of Coherence and anxiety and depression amongst patients at risk of hereditary cancer receiving genetic counseling. When writing this article, 144 patients referred for genetic counseling due to a suspicion of hereditary cancer in the family were recruited for this multicentered longitudinal study on the psychosocial aspects of genetic counseling in Norway. A total of 96 (66%) patients responded to the follow-up survey distributed 6 months after genetic counseling. This survey included the Sense of Coherence-29 Scale, Impact of Event Scale, and Hospital Anxiety and Depression Scale. Multiple regression analyses were applied. Our results show association between cancer-related distress and symptoms of anxiety and depression. Sense of Coherence is significantly associated with both anxiety and depression. The hypothesis of Sense of Coherence buffering cancer-related distress and the possible impact of these findings for genetic counseling are discussed.     

Psychosocial Factors Associated with Quality of Life Among Individuals Attending Genetic Counseling for Hereditary Cancer

The aim of this multicenter study was to explore associations between psychosocial factors (general self-efficacy, perceived availability of social support, cancer-related distress) and health-related quality of life, among individuals at risk for hereditary cancer. One-hundred and twenty one participants with a family history of breast-cancer or colorectal cancer answered a questionnaire 2-4 weeks prior to genetic counseling. The two dimensions of the health-related quality of life measure, mental and physical health were both used as outcome variables. Multiple regression (linear) analyses revealed that increasing degrees of cancer-related distress was related to decreasing degrees of mental health whereas increasing degrees of self-efficacy and social support were related to increasing degrees of this outcome variable. Self-efficacy, self-esteem support and tangible aid seemed to moderate the relationship between cancer-related distress and mental health. These results suggest that self-efficacy and certain resources of social support buffer the negative association between cancer-related distress and mental health, and might be suitable for interventional efforts. Implications for genetic counseling practice are discussed.     

Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized,effectiveness trial

Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated “real-world” implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.     

Risk Perception,Worry and Satisfaction Related to Genetic Counseling for Hereditary Cancer

In this multi center study, genetic counseling for hereditary cancer was evaluated by assessing patients’ worry, perceived risk of developing cancer and satisfaction with genetic counseling. An overall aim was to identify characteristics of vulnerable patients in order to customize genetic counseling. In addition, agreement between patients’ and counselors’ scores was measured. A total of 275 Norwegian patients were consecutively recruited, and 213 completed questionnaires before and after genetic counseling. Patients’ perceived risk decreased after the genetic counseling session. There was incongruence between risk perception expressed as a percentage and in words. Patients were significantly less worried after counseling. Higher levels of worry were predicted by low instrumental satisfaction with counseling, high degree of perceived risk of developing cancer and younger age. In conclusion, counselors met the patients’ psychological needs to a satisfactory degree during counseling. However, patients did not fully understand their risk of developing cancer.     

Postphenomenology: Learning Cultural Perception in Science

In this article I propose that a postphenomenological approach to science and technology can open new analytical understandings of how material artifacts, embodiment and social agency co-produce learned perceptions of objects. In particle physics, physicists work in huge groups of scientists from many cultural backgrounds. Communication to some extent depends on material hermeneutics of flowcharts, models and other visual presentations. As it appears in an examination of physicists’ scrutiny of visual renderings of different parts of a detector, perceptions vary in relation to social and bodily experiences. Vision in physics has seemingly allowed an objective perception at a convenient distance of the body. This article challenges this view and proposes that the variations can be analysed as cultural at two echelons with the help of a postphenomenological approach combined with cultural psychological theory of artifacts. A third echelon presumably constitutes the phenomenological limit to culture in science. Even this last resort of subjectivity can be embraced by a postphenomenological approach. The process of culturalization in physics can be defined as a process of situating knowledge in a body whose continuous learning of micro-and macro perceptions makes scientific renderings unstable. Taken together postphenomenology, following the distinctions between body one and body two, and combined with cultural psychological learning theory, enables new insight into what constitutes culture in science.

Life Satisfaction and Associated Factors Among People Aged 60 Years and Above in Six European Countries

Life satisfaction is a concept frequently used to measure wellbeing of older people. However, there is still a lack of cross-national comparative research investigating factors associated with life satisfaction. There may be unique and common factors associated with life satisfaction across European countries. This study aimed to investigate life satisfaction among people aged 60–89 years in six European countries in relation to health problems, ADL capacity, self-esteem, social and financial resources. A cross-sectional study was performed, including 7,699 people aged 60–89 years, in Sweden, the UK, The Netherlands, Luxemburg, Austria and Italy, participating in the European Study of Adult Wellbeing, using questions from the Older Americans Resources and Services schedule, Multidimensional Functional Assessment Questionnaire, Life Satisfaction Index Z and Rosenberg’s Self-esteem scale. Logistic regression analysis was performed to determine factors associated with life satisfaction in the six national samples. In cases where people were less satisfied with their life it was fairly satisfactory and unsatisfactory social contacts (Odds Ratio (OR) 1.5–13.8), poor financial resources (OR 1.7–15.1), feeling greatly hindered by health problems (OR 2.2–5.4) and self-esteem (OR 2.1–5.1) rather than the ability to perform activities of daily living and the extent of social contacts that gave the greatest risk of low life satisfaction in all the six European countries. There were both common and country-specific factors important for life satisfaction in the six European countries. However, the importance of satisfactory social contacts, financial resources, self-esteem and feeling hindered by health problems seems universal in the six included countries and thus important to target in preventive interventions.
