Mother and infant coordinate heart rhythms through episodes of interaction synchrony

Animal studies demonstrated the powerful impact of maternal-infant social contact on the infant's physiological systems, yet the online effects of social interactions on the human infant's physiology remain poorly understood. Mothers and their 3-month old infants were observed during face-to-face interactions while cardiac output was collected from mother and child. Micro-analysis of the partners’ behavior marked episodes of gaze, affect, and vocal synchrony. Time-series analysis showed that mother and infant coordinate heart rhythms within lags of less than 1 s. Bootstrapping analysis indicated that the concordance between maternal and infant biological rhythms increased significantly during episodes of affect and vocal synchrony compared to non-synchronous moments. Humans, like other mammals, can impact the physiological processes of the attachment partner through the coordination of visuo-affective social signals.     

Psychosoziale Versorgung von Krebspatienten

Objectives

The aim of this study was to determine rates of psychooncological care for cancer inpatients and outpatients under routine conditions in a large University hospital. The percentage of patients who received care was analyzed and compared with self-rated and expert rated supportive care needs.

Methods

The percentage of inpatients who received psychooncological care was calculated by comparing the number of cancer patients treated at the hospital as documented by the local tumor registry (n=1,979) with the number of patients treated by a psychooncologist in that hospital as documented by the hospital??s psychooncological consultation liaison service. The percentage of outpatients who received psychooncological care was calculated by comparing the number of incident cancer cases as documented by the local tumor registry (n=5,886) with the number of patients who received at least one consultation at the local tumor counseling centre. Supportive care needs were estimated by analyzing data of a prospective patient survey in the same hospital (n=1,803) using the Hospital Anxiety and Depression Scale and single items to determine social burden and the wish for emotional support.

Results

The results showed that 11% of inpatients and outpatients (n=234 and n=638, respectively) received psychooncological care. Social care needs were prevalent in 37% and psychological care needs in 52% of the patients during the stay in hospital and in 42% (social and psychological) 6 months later. Of the patients 41% expressed the need to see a social worker and 29% to see a psychologist. Large differences were found between patients with different tumor entities.

Conclusion

Psychooncological care delivered to cancer patients under routine conditions was below the actual rate required as estimated by screening instruments and as expressed by the patients.     

Pr?diktoren tumorassoziierter Fatigue

Fatigue is a serious cancer-related syndrome reported by cancer patients during and after treatment. Especially the impact of chronic fatigue on quality of life is substantial. The aim of this study was to identify predictors of fatigue after finishing treatment from an early stage of the cancer treatment. A sample of 551 cancer patients with heterogeneous diagnoses completed questionnaires assessing fatigue, psychological and psychosomatic data plus treatment data. The patients were recruited from an acute care hospital (t1) and the participants completed the questionnaire 2?C2.5 years after treatment (t2). Regression analysis showed that the strongest predictor of later fatigue was fatigue during the therapy. Other impact factors are radiotherapy and pain. The results suggest that the diagnosis and treatment of acute fatigue should be carried out at an early stage of cancer treatment to prevent chronic fatigue. Suitable diagnostic methods and treatment options will be presented.     

Moving Knowledge into Action: Developing the Rapid Synthesis and Translation Process Within the Interactive Systems Framework

The Interactive Systems Framework (ISF) for Dissemination and Implementation presents an overall framework for translating knowledge into action. Each of its three systems requires further clarification and explanation to truly understand how to conduct this work. This article describes the development and initial application of the Rapid Synthesis and Translation Process (RSTP) using the exchange model of knowledge transfer in the context of one of the ISF systems: the Prevention Synthesis and Translation System (see [special issue “introduction” article] for a translation of the Wandersman et al. (Am J Community Psychol 41:3–4, 2008) article using the RSTP). This six‐step process, which was developed by and for the Division of Violence Prevention at the Centers for Disease Control and Prevention in collaboration with partners, serves as an example of how a federal agency can expedite the transfer of research knowledge to practitioners to prevent violence. While the RSTP itself represents one of the possible functions in the Prevention Synthesis and Translation System, the resulting products affect both prevention support and prevention delivery as well. Examples of how practitioner and researcher feedback were incorporated into the Rapid Synthesis and Translation Process are discussed.

Child and adolescent development: common mental disorders according to age and gender

Despite the increase in the incidence and prevalence rates of children and adolescents' mental disorders, there are few works performed with large and representative samples of children and adolescents with psychopathological symptoms. The present work analyses 588 participants referred by first care pediatricians to a specialized unit for children and adolescents' mental health. As a result of the study, a statistically significant relation was found between age and diagnosis: a larger incidence of behavioral disorders, communication disorders, elimination disorders, pervasive developmental disorders, impulse-control disorders from 0 to 5 years; behavioral disorders and attention deficit hyperactivity disorder (ADHD) were more common from 6 to 11 years, behavioral and anxiety disorders were more likely at 12 to 15 years; and, lastly, behavioral disorders were more prevalent from 16 to 18 years. With respect to gender, there was a significant relationship with diagnosis: boys had more behavioral disorders, whereas girl had more anxiety disorders. To conclude, a relationship between mental disorders and developmental achievements could be indicated in the younger group. Additionally, externalizing disorders in boys and internalizing ones n girls were more prevalent across all ages.     

Cognitive factors and willingness to participate in an HIV vaccine trial among HIV-positive injection drug users

There are gaps in our knowledge of the role cognitive factors play in determining people's willingness to participate (WTP) in therapeutic HIV vaccine trials. Using a cross-sectional study of HIV-positive injection drug users (IDU), we determined the role of three cognitive factors: HIV treatment optimism, self-efficacy beliefs, and knowledge of vaccine trial concepts in relation to WTP in a hypothetical phase 3 therapeutic HIV vaccine trial. WTP was 54%. Participants tended to be low in HIV treatment optimism (mean?=?3.9/10), high in self-efficacy (mean?=?79.8/100), and low in knowledge (mean?=?4.1/10). Items pertaining to HIV treatment optimism and knowledge of HIV vaccine trial concepts were generally unrelated to WTP. An increase in self-efficacy had a statistically significant positive association with WTP (OR?=?1.61, 95% CI?=?1.04-2.46, p?相似文献   

Through the eyes of anxiety: Dissecting threat bias via emotional-binocular rivalry

An extensive body of research has demonstrated that anxious individuals abnormally process threat-related content. Yet, the manner in which clinical anxiety affects the selection of threatening signals and their maintenance within consciousness is yet to be explored. The present study used an emotional binocular rivalry (e-BR) procedure, in which pictures of faces depicting either fearful or neutral expressions competed with pictures of a house for conscious perception. We assumed that first- or cumulative-preferred perception of faces with fearful over neutral expression (i.e., initial or sustained threat bias, respectively) stand for preferential selection or maintenance of fear content in awareness, correspondingly. Unmedicated patients with social anxiety disorder (SAD) and panic disorder (PAD) were compared to healthy controls for threat-related perceptual biases in the e-BR. At first perception of face, both SAD and PAD patients showed a greater initial threat bias than healthy controls. In contrast, at cumulative dwell-time of face, patient groups demonstrated a diminished sustained threat bias relative to healthy controls, yet in a different manner. SAD patients showed a sustained threat bias, though it was smaller than in healthy controls. Furthermore, increased levels of reported anxiety among SAD patients were associated with enhanced sustained perception of neutral faces. PAD patients, on the other hand, showed no sustained threat bias and a diminished cumulative perception of fearful faces with increased levels of anxiety traits. These findings indicate that anxiety disorders commonly involve an initially enhanced selection of threat signals into awareness, followed by disorder-specific manifestation of diminished preferred maintenance of threat in awareness.

EFFECTS OF ETHNICITY,ACCENT, AND JOB STATUS ON SELECTION DECISIONS

The present study investigated the effects of ethnicity, accent, and job status in the selection interview. Two hundred and ten student subjects viewed simulated, videotaped selection interviews in which applicant ethnicity, applicant accent, and job status were manipulated in a completely crossed 3 × 2 × 2 factorial design. Two sets of ratings were obtained, selection decision ratings of the job applicant, and subjective importance ratings based on the previous selection decisions. Significant main effects were obtained for ethnicity and job status in selection decision as predicted. Contrary to predictions however, the main effect for accent was not found significant. Further analysis of the importance ratings indicated a significant main effect for accent, but not for ethnicity. These findings indicated that applicant ethnicity and job status were important in selection interview decision and accent was not. Contrary to this however, subjects considered that accent was important in their selection decision ratings, while ethnicity was not.     

Answering yes-no questions about causes: Question acts and question categories

Three experiments examined the cognitive process of answering yes-no questions about causes. Singer’s VAIL model of question answering predicted that readers would take longer to correctly answer “no” than “don’t know” to such questions. In Experiment 1, the antecedent sentences used either the causal conjunction so orbecause. Experiment 2 compared so with an implicit causal link. In all conditions, the main prediction was strongly supported. However, when the questions referred to brief stories in Experiment 3, correct “no” and “don’t know” response latencies did not differ. It was concluded that (1) VAIL identifies the cognitive operations underlying the answering of causal questions; (2) answering yes-no questions about causes resembles answering yes-no questions about case-filling elements; (3) the yes-no versus wh- distinction is orthogonal to the type of relation asked about; and (4) studying question answering about sentences will contribute to the understanding of question answering about text.     

体操运动员应激反应特点的研究

情绪紧张或应激状态可引起一系列生理生化反应。但是后天的训练和应激经验能否影响这些反应尚所知不多。本实验比较了运动员与非运动员在实验室内完成一复杂辨别反应时,即在与运动无关的应激状态下尿内儿茶酚胺的分泌量、心率、心律、呼吸率和呼吸积分等变化的异同。发现在紧张性作业时运动员尿内几茶酚胺的分泌仅有小量的不显著的增加,而非运动员则有显著增加。运动员和非运动员尿内儿茶酚胺分泌量差别显著。在紧张性作业时运动员和非运动员的心率均有显著增加,R—R间期标准差则均变小。运动员的心率在休息或作业时均比非运动员慢,R—R间期标准差则均大于相应条件下非运动员的。紧张性作业时运动员和非运动员呼吸率均明显增加,作为相对呼吸流量的呼吸积分值均显著下降。运动员的呼吸积分值均低于相应条件下非运动员的,但两组间差异未达显著水平。结果表明后天的训练和应激经验对机体在应激状态下尿内几茶酚胺分泌量、心率、心律、相对呼吸流量等生理反应有不同程度的影响。
