Does fear of movement mediate the relationship between pain intensity and disability in patients following whiplash injury? A prospective longitudinal study

Purpose The purpose of this paper is to investigate the relationship between resting heart rate (RHR) and psychopathy. The literature on heart rate vs criminality (including violence) is quite clear; low RHR is associated with engaging in violent and criminal behavior. However, results are not as consistent for psychopathy. Design/methodology/approach This paper analyzes heart rate measured at ages 18 and 48, and psychopathy at age 48, in the Cambridge Study in Delinquent Development (CSDD). The CSDD is a prospective longitudinal study that has followed 411 boys from childhood to middle age, and measured social and biological factors of interest to the field of criminal psychology. Findings Interestingly, it was only heart rate at age 18 that was negatively and significantly related to psychopathy at age 48. No trends or relationships were found between heart rate at age 48 and psychopathy at age 48. The findings do, however, indicate that low heart rate at age 18 predicts psychopathy at age 48, and the strongest negative relationships are found between low heart rate (beats per minute) and impulsive and antisocial psychopathic symptoms. Originality/value This is the first ever longitudinal study showing that low RHR predicts later psychopathy. Suggestions for future research are outlined.

The Relationship

Limited studies of the association between BDNF levels and delirium have given inconclusive results. This prospective, longitudinal study examined the relationship between BDNF levels and the occurrence of and recovery from delirium. Participants were assessed twice weekly using MoCA, DRS-R98, and APACHE II scales. BDNF levels were estimated using an ELISA method. Delirium was defined with DRS-R98 (score > 16) and recovery from delirium as ≥2 consecutive assessments without delirium prior to discharge. We identified no difference in BDNF levels between those with and without delirium. Excluding those who never developed delirium (n=140), we examined the association of BDNF levels and other variables with delirium recovery. Of 58 who experienced delirium, 39 remained delirious while 19 recovered. Using Generalized Estimating Equations models we found that BDNF levels (Wald χ2=7.155; df: 1, p=0.007) and MoCA (Wald χ2=4.933; df: 1, p=0.026) were associated with recovery. No significant association was found for APACHE II, dementia, age, or gender. BDNF levels do not appear to be directly linked to the occurrence of delirium but recovery was less likely in those with continuously lower levels. No previous study has investigated the role of BDNF in delirium recovery and these findings warrant replication in other populations.

The Relationship

Background. The duration of untreated psychosis has been postulated to be a predictor of clinical outcome in schizophrenia. Although several prospective studies support the relationship, some studies do not. These differences may be due to a number of methodological issues. The objectives of this study are: (i) to address many of the methodological limitations of earlier studies such as variations in sample size and selection, type of treatment provided, differences in measurement of DUP and outcome, and length of follow-up; and (ii) to examine the relationship between DUP and outcome in a prospective longitudinal study.Method. The DUP of 200 consecutive admissions to a first-episode programme was determined. The sample was followed over 2 years and pre-morbid functioning, symptoms, social and cognitive functioning and substance use were assessed longitudinally.Results. Two years after admission to the programme, longer DUP was significantly associated with high levels of positive symptoms and poor social functioning. Independently of other variables, DUP predicted positive symptoms and social functioning at 1 and 2 years.Conclusions. There is evidence that long DUP continues to have an influence on outcome up to 2 years. These results support ongoing efforts for early detection and intervention.
