The impact of the developmental timing of trauma exposure on PTSD symptoms and psychosocial functioning among older adults.

The present study examined the impact of the developmental timing of trauma exposure on posttraumatic stress disorder (PTSD) symptoms and psychosocial functioning in a large sample of community-dwelling older adults (N = 1,995). Specifically, we investigated whether the negative consequences of exposure to traumatic events were greater for traumas experienced during childhood, adolescence, young adulthood, midlife, or older adulthood. Each of these developmental periods is characterized by age-related changes in cognitive and social processes that may influence psychological adjustment following trauma exposure. Results revealed that older adults who experienced their currently most distressing traumatic event during childhood exhibited more severe symptoms of PTSD and lower subjective happiness compared with older adults who experienced their most distressing trauma after the transition to adulthood. Similar findings emerged for measures of social support and coping ability. The differential effects of childhood compared with later life traumas were not fully explained by differences in cumulative trauma exposure or by differences in the objective and subjective characteristics of the events. Our findings demonstrate the enduring nature of traumatic events encountered early in the life course and underscore the importance of examining the developmental context of trauma exposure in investigations of the long-term consequences of traumatic experiences.

People believe it is plausible to have forgotten memories of childhood sexual abuse.

Pezdek, Blandon-Gitlin, and Gabbay (2006) found that perceptions of the plausibility of events increase the likelihood that imagination may induce false memories of those events. Using a survey conducted by Gallup, we asked a large sample of the general population how plausible it would be for a person with longstanding emotional problems and a need for psychotherapy to be a victim of childhood sexual abuse, even though the person could not remember the abuse. Only 18% indicated that it was implausible or very implausible, whereas 67% indicated that such an occurrence was either plausible or very plausible. Combined with Pezdek et al.s' findings, and counter to their conclusions, our findings imply that there is a substantial danger of inducing false memories of childhood sexual abuse through imagination in psychotherapy.

Does predation control adult sex ratios and longevities in marine pelagic copepods?

We assess the causes of adult sex ratio skew in marine pelagic copepods by examining changes in these ratios between the juveniles and adults, sexual differences in juvenile stage durations, and mortality rates of adults in the field and laboratory (when free from predators). In the field, late copepodite stages (CIV and CV) commonly have sex ratios that are either not significantly different from equity (1 : 1), or slightly male biased. By contrast, in adults, these ratios are commonly significantly biased toward female dominance. Sex ratio skews are therefore primarily attributable to processes in adults. Members of the non-Diaptomoidea have especially skewed adult ratios; in the members Oithonidae and Clausocalanidae this is not generated from differences between male and female adult physiological longevity (i.e., laboratory longevity when free of predators). In the genera Acartia, Oithona, and Pseudocalanus, we estimate that predation mortality contributed ≥ 69% of the field mortality rate in adult males, whereas in Acartia, Oithona, and Calanus adult females, this is ≥ 36%.We conclude that (1) adult sex ratio skew in pelagic copepods is primarily due to differential mortality of the sexes in the adult stage and not in juveniles, (2) mortality rates of adult Acartia, Pseudocalanus, and Oithona are dominated by predation mortality rather than physiological longevity (except under extreme food limitation), and (3) in Pseudocalanus and Oithona, elevated mortality rates in adult males to females is predominantly due to higher predation on males. Our work demonstrates that we now need to develop a more comprehensive understanding of the importance of feeding preferences in predators. Continue reading full article

The Association Between Childhood Trauma and Memory Functioning in Schizophrenia

Objective: Both neurocognitive impairments and a history of childhood abuse are highly prevalent in patients with schizophrenia. Childhood trauma has been associated with memory impairment as well as hippocampal volume reduction in adult survivors. The aim of the following study was to examine the contribution of childhood adversity to verbal memory functioning in people with schizophrenia. Methods: Eighty-five outpatients with a Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) diagnosis of chronic schizophrenia were separated into 2 groups on the basis of self-reports of childhood trauma. Performance on measures of episodic narrative memory, list learning, and working memory was then compared using multivariate analysis of covariance. Results: Thirty-eight (45%) participants reported moderate to severe levels of childhood adversity, while 47 (55%) reported no or low levels of childhood adversity. After controlling for premorbid IQ and current depressive symptoms, the childhood trauma group had significantly poorer working memory and episodic narrative memory. However, list learning was similar between groups. Conclusion: Childhood trauma is an important variable that can contribute to specific ongoing memory impairments in schizophrenia.

Negotiation of risk in sexual relationships and reproductive decision-making amongst HIV sero-different couples

The paper focuses on the ways in which medical discourses of HIV transmission risk, personal bodily meanings and reproductive decision-making are re-negotiated within the context of sero-different relationships, in which one partner is known to be HIV-positive. Eighteen in-depth interviews were conducted with 10 individuals in Northern Ireland during 2008–2009. Drawing on an embodied sociological approach, the findings show that physical pleasure, love, commitment, a desire to conceive without medical interventions and a dislike of condoms within regular ongoing relationships, shaped individuals' sense of biological risk. In addition, the subjective logic that a partner had not previously become infected through unprotected sex prior to knowledge of HIV status and the added security of an undetectable viral load significantly impacted upon women's and, especially, men's decisions to have unprotected sex in order to conceive. The findings speak to the importance of reframing public health campaigns and clinical counselling discourses on HIV risk transmission to acknowledge how couples negotiate this risk, alongside pleasure and commitment within ongoing relationships.

Multidimensional rehabilitation programmes for adult cancer survivors

This is the protocol for a review and there is no abstract. The objectives are as follows:

To assess the effectiveness of multidimensional rehabilitation programs in terms of maintaining or improving the physical and psychosocial well-being of adult cancer survivors.

The review will evaluate the extent to which:

Professionally led multidimensional rehabilitation programs achieve better outcomes than standard services for patients with cancer and their caregivers
Rehabilitation programmes exert a different impact on different domains (e.g. psychological health, physical functioning)
Different modes of delivery and different settings influence outcomes
There is relationship between the number, duration and intensity of rehabilitation sessions and degree of change in measured outcomes.

Predicting family caregiver psychosocial functioning in palliative care

Health professionals are expected to support family caregivers of patients requiring palliative care. However, there is a dearth of empirical evidence to help clinicians identify caregivers who might be at risk of poor psychosocial functioning.

Sexual offences against children: An exploration of attrition in the Northern Ireland criminal justice system

Objective: This paper uses data provided by the Police Service for Northern Ireland (PSNI) to compare the characteristics and outcomes of reported sexual offences involving child and adult victims and explore the factors associated with case outcomes.
Method: PSNI provided data on 8,789 sexual offences recorded between April 2001 and March 2006. Case outcomes were based on whether a case was recorded by police as having sufficient evidence to summons, charge, or caution an offender (detected). Where an offender was summonsed, charged, or cautioned, this is classified as detection with a formal sanction. A case can also be classified as "detected" without a formal sanction. The analysis focused on two key categories of detection without formal sanction: cases in which the police deem there to be sufficient evidence to charge an offender but took no further action because the victim did not wish to prosecute, or because the police or the Public Prosecution Service (PPS) decided that no useful purpose would be served by proceeding.
Results: The analysis confirmed that the characteristics of recorded sexual offences involving adult and child victims vary significantly according to gender, offence type, the timing of report and victim-offender relationship. Almost half of child sex abuse cases are not detected by police and a quarter do not proceed through the criminal justice system because either the victim declines to prosecute or the Police/PPS decide not to proceed. Only one in five child cases involved detection with a formal sanction. Child groups with lower detection with formal sanction rates included children under 5, teenagers, those who do not report when the abuse occurs but disclose at a later date; and those who experience abuse at the hands of peers and adults known to them but not related. The analysis also highlighted variation in formal sanction rates depending on where the offence was reported.
Conclusions: Consideration needs to be given to improving the criminal justice response to specific child groups as well as monitoring detection rates in different police areas in order to address potential practice variation.
Practice implications: Consideration needs to be given to improving the professional response in relation to with particularly lower detection with formal sanction rates. There is also a need to monitor case outcomes to ensure that child victims in different areas receive a similar service.

Prenatal hypoxia leads to increased muscle sympathetic nerve activity, sympathetic hyperinnervation, premature blunting of NPY signalling and hypertension in adult life

Adverse conditions prenatally increase the risk of cardiovascular disease, including hypertension. Chronic hypoxia in utero (CHU) causes endothelial dysfunction, but whether sympathetic vasoconstrictor nerve functioning is altered is unknown. We, therefore, compared in male CHU and control (N) rats muscle sympathetic nerve activity, vascular sympathetic innervation density, and mechanisms of sympathetic vasoconstriction. In young (Y)-CHU and Y-N rats (≈3 months), baseline arterial blood pressure was similar. However, tonic muscle sympathetic nerve activity recorded focally from arterial vessels of spinotrapezius muscle had higher mean frequency in Y-CHU than in Y-N rats (0.56±0.075 versus 0.33±0.036 Hz), and the proportions of single units with high instantaneous frequencies (1–5 and 6–10 Hz) being greater in Y-CHU rats. Sympathetic innervation density of tibial arteries was ≈50% greater in Y-CHU than in Y-N rats. Increases in femoral vascular resistance evoked by sympathetic stimulation at low frequency (2 Hz for 2 minutes) and bursts at 20 Hz were substantially smaller in Y-CHU than in Y-N rats. In Y-N only, the neuropeptide Y Y1-receptor antagonist BIBP3226 attenuated these responses. By contrast, baseline arterial blood pressure was higher in middle-aged (M)-CHU than in M-N rats (≈9 months; 139±3 versus 126±3 mmHg, respectively). BIBP3226 had no effect on femoral vascular resistance increases evoked by 2 Hz or 20 Hz bursts in M-N or M-CHU rats. These results indicate that fetal programming induced by prenatal hypoxia causes an increase in centrally generated muscle sympathetic nerve activity in youth and hypertension by middle age. This is associated with blunting of sympathetically evoked vasoconstriction and its neuropeptide Y component that may reflect premature vascular aging and contribute to increased risk of cardiovascular disease

Evaluation of a partnership between primary and secondary care providing an accessible Level 1 sexual health service in the community

Comprehensive testing for asymptomatic sexually transmitted infections in Northern Ireland has traditionally been provided by genitourinary medicine clinics. As patient demand for services has increased while budgets have remained limited, there has been increasing difficulty in accommodating this demand. In May 2013, the newly commissioned specialist Sexual Health service in the South Eastern Trust sought to pilot a new model of care working alongside a GP partnership of 12 practices. A training programme to enable GPs and practice nurses to deliver Level 1 sexual health care to heterosexual patients aged >16 years, in accordance with the standards of BASHH, was developed. A comprehensive care pathway and dedicated community health advisor supported this new model with close liaison between primary and secondary care. Testing for Chlamydia, gonorrhoea, HIV and syphilis was offered. The aims of the pilot were achieved, namely to provide accessible, cost-effective sexual health care within a framework of robust clinical governance. Furthermore, it uncovered a high positivity rate for Chlamydia, especially in young men attending their general practice, and demonstrated a high level of patient satisfaction. Moreover the capacity of secondary care to deliver Levels 2 and 3 services was increased.

Explanations for child sexual abuse given by convicted offenders in Malawi:no evidence for "HIV cleansing"

OBJECTIVE: A commonly cited, but unproven reason given for the rise in reported cases of child sexual abuse in Sub-Saharan Africa is the "HIV cleansing myth"-the belief that an HIV infected individual can be cured by having sex with a child virgin. The purpose of this study was to explore in Malawi the reasons given by convicted sex offenders for child sexual abuse and to determine if a desire to cure HIV infection motivated their offence.

METHODS: Offenders convicted of sexual crimes against victims under the age of 18 were interviewed in confidence in Malawi's two largest prisons. During the interview the circumstances of the crime were explored and the offenders were asked what had influenced them to commit it. Each participant was asked the closed question "Did you think that having sex with your victim would cure or cleanse you from HIV?"

RESULTS: 58 offenders agreed to participate. The median (range) age of offenders and victims was 30 (16-66) years and 14 (2-17) years, respectively. Twenty one respondents (36.2%) denied that an offence had occurred. Twenty seven (46.6%) admitted that they were motivated by a desire to satisfy their sexual desires. Six (10.3%) stated they committed the crime only because they were under the influence of drugs or alcohol. None of the participants said that a desire to cure or avoid HIV infection motivated the abuse.

CONCLUSION: This study suggests that offenders convicted of a sexual crime against children in Malawi were not motivated by a desire to be cured or "cleansed" from HIV infection. A need to fulfil their sexual urges or the disinhibiting effect of drugs or alcohol was offered by the majority of participants as excuses for their behaviour.

Autistic Functioning and Language Development

This thesis is a retrospective qualitative study based on psychotherapy sessions with children presenting autistic features who use language in atypical ways. The aim was to understand, through the transferential relationship, what psychological context in terms of anxieties and defences prevents the child from using language efficiently. Hypotheses concerning children‘s use of language in the context of their emotional oscillation and evolution during the course of treatment were noted and checked against subsequent developments. They were also triangulated with the outcome of a grounded theory analysis. The grounded theory analysis led to the emergence of higher-level themes that were compared within and across cases and allowed factors surrounding the children‘s use of language to be conceptualized. The grounded theory method was used in parallel with the usual process of evaluation of the dynamics of each session and patient used by psychoanalysts a posteriori and which is part of the researcher‘s background. This procedure was enhanced by the use of Bion‘s Grid, here in a version adapted to the aims of the research. This approach is discussed in detail in the Methodology chapter. The psychoanalytic theoretical background that supported the research was mainly based on the tradition of Object-Relations Theory, particularly the evolution of Kleinian thinking represented by Bion‘s works, and as far as autism is concerned, by Frances Tustin and Donald Meltzer‘s formulations. Concerning the subject of language development, Meltzer‘s explorations on the necessary conditions for its development and the philosopher Wittgenstein‘s investigations on the social function of language were the main influences of this work. The evolution of the children‘s use of language in parallel with their emotional development in the context of their psychotherapies was analyzed and some hypotheses about the oscillations in their emotional and mental functioning were made. The oscillation in the children‘s emotional state, language use and thinking processes was also studied in terms of a general fluctuation between different mental states that was considered to be present in different degrees and quality in mental life and more strongly when there are limitations in communication skills and social interaction. A few excerpts from notes on adolescent and adult cases with autistic features were included in the Discussion Chapters to briefly illustrate this aspect.

Profiles of ageing in the South of Portugal: education and cognitive functioning in elderly persons living in institutionalized and community contexts

The region of the Algarve shows huge differences between the coastline where population in the urban areas grows, and the inland rural areas, in some cases very isolated, which frequently have high ageing indexes. This general scenario, with an elderly population with very different economic and social conditions, frames the ongoing PhD research designed as a cross-sectional study of an intentional sample of elderly persons. The basic theoretical framework departs from the perspective of developmental psychology of life-span and the model of selection, optimisation and compensation for optimal ageing (Baltes & Baltes, 1990; Freund & Baltes, 2002). The present study is a first step in the analysis of empirical data collected in the PhD sample (N=156; age range 65 to 97 years; M = 80.4 years; SD = 7.2 years). Its purpose is to assess the cognitive functioning of participants, screening for cognitive impairment and examine the relations between the cognitive status of the subjects and a number of selected variables including educational level, age, physical activity and living contexts of the subjects. We accessed the cognitive status of the participants with the Portuguese version of Mini Mental State Examination (MMSE) finding a 10.3% prevalence of positive cases with cognitive impairment. The results also show significant relationships between the cognitive status accessed by the MMSE and educational level, professional qualification, age, living arrangement and activity level of the participants. The relationship verified between educational level and cognitive status of the participants was the largest correlation found in the study with the variability in educational level accounting for 44.8% of the variability in MMSE score. This results points in the same direction of several lines of research that corroborate the strong intercorrelation between education and cognitive functioning in old age.

Impact of job insecurity on sexual desire: an exploratory analysis.

To explore, for the first time, the impact of job insecurity on sexual desire. Cross-sectional analysis of a nationally representative sample of 7247 individuals aged 20-64 years working as full or part-time employees in Switzerland. The logistic regression analysis showed that workers aged 20-49 years perceiving high levels of job insecurity are exposed to a significantly higher risk of decrease of sexual desire compared to the reference group. The risk is 53% higher among men (OR 1.53; 95% CI 1.16-2.01) and 47% for woman (OR 1.47; 1.13-1.91). No increased risk was found for employees aged 50-64 years old. An increasing fear of job loss is associated with a deterioration in sexual desire. These first preliminary findings should promote further epidemiological and clinical prospective studies on the impact of job insecurity on intimate relationships and sexual dysfunction.

Effects of female postmating odour on male sexual behaviour, in Heliconius butterflies /

The effects of the female postmating odour on male sexual behaviour were examined in Heliconius erato and H. charithonia (Lepidoptera: Nymphalidae). Predictions from the antiaphrodisiac hypothesis were tested using the two reproductive strategies of these species. Within the pupal mating strategy, results from behavioural experiments quantified and statistically tested dispersal rates of pupal-perched males to the presence of stimuli with and without the postmating odour. Results do not support an antiaphrodisiac function to the postmating odour. Similarly, within the adult courtship strategy, behavioural test results indicate that males do not alter their expenditure of energy in terms of either the duration or frequency of courtship behaviours elicited by females with and without the postmating odour. The data from both experiments did not support the antiaphrodisiac hypothesis for the function of the female postmating odour. A novel hypothesis predicting that the postmating female odour acts as an oviposition-deterring pheromone is presented.
