Salivary concentrations of cortisol and testosterone and prediction of performance in a professional triathlon competition

The aim of this study was to examine salivary cortisol and testosterone concentrations in professional male athletes during a short triathlon competition using non-invasive methods, and to determine whether these hormone concentrations could be accurate predictors of performance. Eight adult male athletes (age, mean ± SEM: 27.8 ± 3.2 years; body mass index: 21.66 ± 0.42) in a professional triathlon team volunteered to participate in this study. Saliva samples were taken on the competition day and 7 days after competition on a rest day. The performance of the athletes was assessed by their rank order in the competition. Salivary cortisol concentrations were greater on the competition day than on the rest day in the early morning, immediately after waking up, 30 min later, immediately before the start of the competition, and later in the evening. Testosterone concentrations were greater on the competition day in the morning and in the evening. The diurnal rhythm of both cortisol and testosterone concentrations was maintained on both days and the testosterone/cortisol ratio (T/C ratio) was similar between days. The performance of the athletes was positively correlated with salivary cortisol concentration in the early morning of the competition day, but was not correlated with testosterone concentrations at any of the time points. In conclusion, early morning salivary cortisol concentration, but not T/C ratio, could be used to predict performance in athletes during a professional triathlon competition.     

Synchronicity,the infinite unrepressed,dissociation and the interpersonal

This paper uses the logic derived by Matte Blanco to provide an Archimedean point and a mathematics, both of which Jung complained of lacking, with which to validate the notion of synchronicity and to demonstrate that it is one of the inevitable properties of an unconscious which is unrepressed such as Jung's collective unconscious, and that such an unconscious will also be affective and interpersonal as well as intrapersonal. These have important clinical implications. After an exposition of Matte Blanco's thinking, some clinical material is presented of an episode in which patient and author both suffered the same psychosomatic symptom some time just prior to a session. Correspondences between Matte Blanco's logically derived ideas and Jung's phenomenological observations are made.     

Effect of Nonspecific Chronic Low Back Pain on Walking Economy: An Observational Study

The authors investigated the effects of chronic low back pain (LBP) and walking speed (WS) on metabolic power and cost of transport (CT). Subjects with chronic nonspecific LBP (LBP group [LG]; n = 9) and healthy (control group [CG]; n = 9) were included. The test battery was divided into 3 blocks according to WS as follows: preferred self-selected speed (PS), and lower and higher than the PS. In each block, the volunteers walked 5 min, during which oxygen consumption was measured. Although without differences between groups, the LG had CT lower in slower speeds than in faster speeds. Walking speed affected CT only in the LG, which the group had the greatest walking economy at slower speeds.     

Early control of reaching: effects of experience and body orientation

Although research suggests that experience may be a better indicator of the acquisition of certain abilities by infants than age, little work addresses this issue in the development of reaching movements in particular. This longitudinal study fills this gap by verifying the effect of practice time on more- and less-skilled reachers of the same age group in different body orientations. Less- (n=6) and more-skilled (n=4) reachers were evaluated at the acquisition of reaching and again after 1 month of spontaneous practice. Kinematic analyses examined 3D wrist motion during reaching trials in supine (0 degrees ), reclined (45 degrees ) and seated (70 degrees ) orientations. The results indicated that skill level was a relevant factor in dealing with gravitational constraints imposed by different body orientations. Time of practice affected the way less- and more-skilled reachers explored and adapted the kinematic parameters of reaching to constraints imposed by body orientations. These findings suggest that not only age, but also experience and body orientations are important constraints that should be taken into account when examining infant reaching development.     

Reducing workplace bias toward people with disabilities with the use of imagined contact

In this research we test the effectiveness of imagined intergroup contact as an intervention that improves attitudes toward people with disabilities in organizational settings. We conducted two experimental studies with the aim of examining the bias‐reduction effects of imagined contact on attitudes toward people with disabilities. Furthermore, we examined how imagined contact can be most effective in improving attitudes in work situations. Both studies yielded evidence that the imagined contact intervention significantly impacted on two dependent variables: expected work‐related outcomes and support for the rights of people with disabilities, via enhancing the belief in performance level. We discuss the results in the context of developing effective and accessible intervention tools, which can be used in workplace trainings, and can promote anti‐discriminatory policies in organizations.     

Psychometric Assessment of the Child Surgery Worries Questionnaire Among Portuguese Children

Worries are common in surgical patients, especially in children. The present study analyzed the factor structure and the psychometric properties of a Portuguese version of the Child Surgery Worries Questionnaire (CSWQ-P) in a Portuguese sample of 490 children. Exploratory factor analysis, conducted via principal axis factoring with oblimin rotation, provided evidence for a four-factor structure of the 21 item questionnaire. A confirmatory factor analysis was also conducted, showing the good fit of this solution. The CSWQ-P proved to have one more subscale than the original Spanish version CSWQ. Correlations with the children’s trait anxiety provided evidence of convergent validity for the CSWQ-P. Females also scored higher on worries than males on all subscales. Psychometric properties of this revised version of the CSWQ provided support for use with young children, and indicate the CSWQ-P has value for use in healthcare practice and in clinical research.     

Resilience,religiosity and treatment adherence in hemodialysis patients: a prospective study

Resilience and religiosity have received attention as an important process in the experience and management of chronic comorbidities; however, there is no study evaluating resilience in hemodialysis patients and its association with other psychological dimensions or with treatment adherence. This observational prospective study assessed resilience (25 item Wagnild and Young Resilience Scale), religiosity under three dimensions (organizational, non-organizational and intrinsic) using DUREL scale, depressive symptoms (Patient Health Questionnaire-9) and health-related quality of life (Short Form-36 questionnaire). The main outcomes were medication adherence using the Morisky Medication Adherence Scale-8 (MMAR-8) and the missing/shortened dialysis sessions in the following six months. Of 208 patients approached, 202 (97.1%) agreed to participate. One hundred twenty-three patients (60.9%) were males and mean age was 52.8 ± 14.8 years-old. The median time on hemodialysis was 36 months (IQR, 12, 84). 82 (40.6%) patients obtained a MMAS-8 score <6 and were considered as having ‘poor adherence’. Overall, the mean score of medication adherence was low (5.7 ± 2.1). About adherence to hemodialysis sessions, patients missed a total of 234 (1.6%) hemodialysis sessions. Forty-eight patients (23.7%) missed an average of at least three sessions in six months. Regarding adherence to medication, there was no association in the uni- or multivariate analysis between religiosity dimensions and MMAS-8 score. After adjustment, resilience was positively associated with MMAS-8 score (standardized β coefficient .239, p = .016). Organized and intrinsic religiosity were associated with adherence to dialysis sessions (standardized β coefficient .258, p = .004 and .231, p = .026, respectively). Interestingly, opposite to medication adherence, more resilient patients were associated with less adherence to hemodialysis sessions (standardized β coefficient ?.296, p = .001). Religiosity was associated with dialysis adherence but not with medication adherence. Resilience was associated with higher medication adherence but lower adherence to dialysis sessions.     

Ecological Contexts in Adolescent Pregnancy: The Role of Individual,Sociodemographic, Familial and Relational Variables in Understanding Risk of Occurrence and Adjustment Patterns

Adolescent pregnancy appears today as an intricate tapestry where different dimensions interact. In our study we examined the associations between individual, sociodemographic, familial, and relational variables and their impact on the occurrence of pregnancy and adolescents’ adjustment to it. Participants were Portuguese pregnant and non-pregnant adolescents (N = 833). Ecological contexts were characterized, and individual and relational adjustment (depressive symptoms and quality of life; perceived quality of relationship with significant others—parents, romantic partner and friends) were evaluated. Differences between the ecologies of adolescents in both groups were identified. Familial and relational variables were significantly associated with both the risk of pregnancy and more difficulties in adjustment. Implications for preventive intervention are discussed.
