What mediates psychopathology in stalking victims? The role of individual-vulnerability and stalking-related factors

Stalking victims report significant psychiatric morbidity, which often persists long after the stalking itself has ceased. Elucidating predictors of psychopathology in victims is critical to informing the clinical management of this population. This study examined demographic, individual-vulnerability and stalking-related predictors of general psychopathology and post-traumatic stress in a community sample of victims (n = 236). Regression analyses showed that both general psychopathology and post-traumatic stress were influenced by individual-vulnerability factors, particularly the use of avoidance coping, and stalking-related factors, most notably being subjected to threats. This study provides the most comprehensive analysis to date of factors that mediate psychiatric morbidity among stalking victims, and highlights the utility of clinicians focussing on modifying dynamic risk factors such as maladaptive avoidance behaviours to help alleviate victims' psychological distress.

Problem sexual behaviour in children: a review of the literature

   Although there is an under-acknowledgement of the issue in Australia there is a large body of international scholarship on juveniles who exhibit sexually violent or coercive behaviours toward other juveniles. Research undertaken in the United States and the United Kingdom emphasises options for clinical treatment, the logistics of coordinating multi agency response, and the causes and correlatives for coercive sexual behaviours in adolescents. Much of this literature has tended to focus on adolescents and there is an urgent need for increased studies on young children engaging in problem sexual behaviour.

   The smaller body of work published in Australia also favours adolescents rather than children with much of this work heavily influenced by international clinical studies. There are, however, a handful of reports based on Australian practitioner data that do focus on young children who engage in problem sexual behaviour. This literature surveys and evaluates the very limited number of existing therapeutic programs in Australia, and provides interview data with practitioners working with children exhibiting problem sexual behaviour. In the main, this research reinforces the findings of the internationa scholarship, both in terms of the contributing factors to problem sexual activity in children, but also in terms of the need for multi-faceted and contextually based cognitive behavioural therapeutic programs in response. More importantly, this burgeoning field of study indicates how far we have to go both in understanding the extent of the problem in Australia and in fashioning appropriate programs for prevention and intervention. Dr Joe Tucci is Chief Executive Officer of the Australian Childhood Foundation (ACF), an organisation that has taken a lead in responding to childhood problem sexual behaviour. Tucci et al., (2006) claim an urgent need for investment in a dedicated research and response agenda (Staiger et al., 2005b). To effectively address this issue researchers and practitioners require comprehensive empirical data on problem sexual behaviour in children across all sectors of Australian society, including Indigenous communities.

Acute effect of sorghum flour-containing pasta on plasma total polyphenols, antioxidant capacity and oxidative stress markers in healthy subjects: a randomised controlled trial

SUMMARY
Background & aims
It has been previously reported that pasta containing wholegrain sorghum flour exhibits high content of polyphenols and antioxidant capacity and hence might enhance antioxidant status and reduce markers of oxidative stress in vivo; however no clinical studies have yet been reported. Therefore, the present study assessed the effect of pasta containing red or white wholegrain sorghum flour on plasma total polyphenols, antioxidant capacity and oxidative stress markers in humans. The study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN: 12612000324819).

Methods
In a randomised crossover design, healthy subjects (n = 20) consumed three test meals of control pasta (CP), 30% red sorghum pasta (RSP) or 30% white sorghum pasta (WSP), 1–2 wk apart. The test meals were consumed as breakfast after an overnight fast. Blood samples were obtained at fasting and 2 h after consumption and analysed for total polyphenols, antioxidant capacity, superoxide dismutase (SOD) activity, protein carbonyl and 8-isoprostanes.

Results
Compared to baseline, the 2 h post-prandial levels following the RSP meal of plasma polyphenols, antioxidant capacity and SOD activity were significantly (P < 0.001) higher while the protein carbonyl level was significantly lower (P = 0.035). Furthermore, net changes in polyphenols, antioxidant capacity and SOD activity were significantly (P < 0.001) higher while protein carbonyl were significantly (P = 0.035) lower following consumption of the RSP meal than the CP meal.

Conclusion
The results demonstrated that pasta containing red wholegrain sorghum flour enhanced antioxidant status and diminished marker of oxidative stress in healthy subjects.

Investigation of consumer satisfaction with cognitive-behaviour therapy and sertraline in the treatment of adolescent depression

Objective: A new instrument, the Adolescent Depression Treatment Satisfaction Questionnaire (ADTSQ) was devised to measure the consumer satisfaction of depressed adolescents and their parents. The objectives of the paper were to present the psychometric proper ties ofthe ADTSQ and to investigate the relative consumer satisfaction with cognitive-behavioural therapy (CBT), sertraline (SRT) and a combined treatment of CBT and SRT (COMBINED) for the treatment of adolescent depression. In addition, participants were asked to rank their most preferred treatment from the following approaches: medication, individual counselling, group program and family therapy.Method: Thirty-eight adolescents with a unipolar depressive disorder and 37 parents who participated in a randomized clinical trial of CBT versus SRT versus COMBINED completed the ADTSQ following the completion of acute treatment.Results: The ADTSQ was found to have high internal consistency and exploratory factor analysis detected three underlying factors. High levels of consumer satisfaction were reported by both adolescents and parents in all three treatments. Those treated with CBT treatments reported higher levels of skill acquisition than those treated with SRT. Of the four treatment approaches, most parents and adolescentsrated individual counsellingas their first preference.Conclusions: The ADTSQ is a useful measure of consumer satisfaction for depressed adolescents and their parents. CBT, SRT and COMBINED were shown to have high consumer satisfaction with CBT's higher skills training content reflected in the participants' reports. Individual counselling was perceived as the most favourable choice of treatment for adolescent depression. Although limitations associated with the measurement of consumer satisfaction and of the study are acknowledged, it is recommended that the inclusion of consumer satisfaction measures be considered in clinical trials that examine treatment efficacy.

Association between attributions of responsibility for motor vehicle crashes, depressive symptoms, and return to work.

Perceptions surrounding the underlying causes of accidents and injuries may be a key mechanism influencing postaccident health and functional outcomes among people injured in road crashes. In particular, attributions of responsibility may influence rates of postcrash depressive symptomatology and return-to-work.

Feasibility of conducting a palliative care randomized controlled trial in children with advanced cancer: assessment of the PediQUEST study

Pediatric palliative care randomized controlled trials (PPC-RCTs) are uncommon.

N-acetyl cysteine in the treatment of obsessive compulsive and related disorders: a systematic review

Obsessive compulsive and related disorders are a collection of debilitating psychiatric disorders in which the role of glutamate dysfunction in the underpinning neurobiology is becoming well established. N-acetyl cysteine (NAC) is a glutamate modulator with promising therapeutic effect. This paper presents a systematic review of clinical trials and case reports exploring the use of NAC for these disorders. A further objective was to detail the methodology of current clinical trials being conducted in the area.

Symptoms and distress in children with advanced cancer: prospective patient-reported outcomes from the PediQUEST Study

PURPOSE: Thousands of children are living with advanced cancer; yet patient-reported outcomes (PROs) have rarely been used to describe their experiences. We aimed to describe symptom distress in 104 children age 2 years or older with advanced cancer enrolled onto the Pediatric Quality of Life and Evaluation of Symptoms Technology (PediQUEST) Study (multisite clinical trial evaluating an electronic PRO system).

METHODS: Symptom data were collected using age- and respondent-adapted versions of the PediQUEST Memorial Symptom Assessment Scale (PQ-MSAS) at most once per week. Clinical and treatment data were obtained from medical records. Individual symptom scores were dichotomized into high/low distress. Determinants of PQ-MSAS scores were explored using linear mixed-effects models.

RESULTS: During 9 months of follow-up, PQ-MSAS was administered 920 times: 459 times in teens (99% self-report), 249 times in children ages 7 to 12 years (96% child/parent report), and 212 times in those ages 2 to 6 years (parent reports). Common symptoms included pain (48%), fatigue (46%), drowsiness (39%), and irritability (37%); most scores indicated high distress. Among the 73 PQ-MSAS surveys administered in the last 12 weeks of life, pain was highly prevalent (62%; 58% with high distress). Being female, having a brain tumor, experiencing recent disease progression, and receiving moderate- or high-intensity cancer-directed therapy in the prior 10 days were associated with worse PQ-MSAS scores. In the final 12 weeks of life, receiving mild cancer-directed therapy was associated with improved psychological PQ-MSAS scores.

CONCLUSION: Children with advanced cancer experience high symptom distress. Strategies to promote intensive symptom management are indicated, especially with disease progression or administration of intensive treatments.

Physical functioning, emotional, and behavioral problems in children with ADHD and comorbid ASD : a cross-sectional study

OBJECTIVE: To examine (a) physical and daily functioning in children with ADHD and autism spectrum disorder (ASD) compared with ADHD alone and (b) whether decreased physical quality of life (QoL) is associated with increased emotional and behavioral problems in children with ADHD-ASD. METHOD: Cross-sectional study comprising 392 children with confirmed ADHD (ADHD-ASD, n = 93; ADHD alone, n = 299) recruited from 21 pediatric practices in Victoria, Australia. Data were collected via parent and teacher surveys. Key measures included the Strengths and Difficulties Questionnaire (SDQ) and Pediatric Quality of Life Inventory (PedsQL). RESULTS: Children with ADHD-ASD had poorer QoL across both psychosocial and physical health domains, and also had greater parent-reported behavioral, emotional, and peer problems, compared with children with ADHD alone. Poorer physical QoL partially mediated the relationship between comorbid ASD status and poorer emotional and behavioral functioning. CONCLUSION: The comorbid overlay of ASD in ADHD appears to influence not only problems in physical functioning but also the severity of problems relating to areas of emotional and behavioral functioning.

Parenting behaviors and nutrition in children with leukemia

The aim of this study was to examine whether parenting behaviors are associated with child nutrition amongst pre-school children receiving treatment for acute lymphoblastic leukemia (ALL), and to determine whether this association differs from that observed amongst a healthy population. Participants were 73 parents of children aged 2–6 years. The children were either a) receiving treatment for ALL (n = 43), or b) had no major medical history (n = 30). Participants completed psychometrically validated questionnaires that assessed parenting behaviors and child diet. Increased parental overprotection was associated with higher fruit and vegetable consumption for the control group but lower fruit and vegetable consumption for the ALL group. Parental overprotection, inconsistent discipline and emotional feeding were positively associated with non-core (“junk”) food consumption for the ALL group, particularly those who had recently received steroid treatment. To the best of our knowledge, this is the first study to show that certain parenting behaviors may be associated with poor nutrition during treatment for ALL. In light of these results, parenting interventions, specifically targeting parenting behaviors such as assertive discipline, may be a mechanism for nutrition promotion amongst this vulnerable group.

Associations between dehydroepiandrosterone (DHEA) levels, pituitary volume, and social anxiety in children

 Early timing of adrenarche, associated with relatively high levels of dehydroepiandrosterone (DHEA) and its sulphate (DHEA-S) in children, has been linked with mental health problems, particularly anxiety. However, little is known about possible neurobiological mechanisms underlying this association. The pituitary gland is a key component of the hypothalamic–pituitary–adrenal (HPA) axis, the activation of which triggers the onset of adrenarche. The purpose of this study was to examine the extent to which pituitary gland volume mediated the relationship between levels of DHEA/DHEA-S relative to age (i.e., adrenarcheal timing) and symptoms of anxiety in 95 children (50 female, M age 9.50 years, SD 0.34 years). Relatively high DHEA and DHEA-S (DHEA/S) levels were found to be associated with larger pituitary gland volumes. There was no significant direct effect of relative DHEA/S levels on overall symptoms of anxiety. However, results supported an indirect link between relatively high DHEA/S levels and symptoms of social anxiety, mediated by pituitary gland volume. No sex differences were observed for any relationship. Our findings suggest that neurobiological mechanisms may be partly responsible for the link between relatively early adrenarche and anxiety symptoms in children. One possible mechanism for this finding is that an enlarged pituitary gland in children experiencing relatively advanced adrenarche might be associated with hyper-activity/reactivity of the HPA axis. Further research is needed to understand the role of stress in the link between adrenarcheal timing and HPA-axis function, especially in relation to the development of anxiety symptoms in children and adolescents.

Transforming narratives of colonial danger: imagining the environments of New Zealand and Australia in children's literature, 1862–1899

Nineteenth-century British children’s literature set in Australia and New Zealand fixates on the dangers of colonial environments. This chapter examines four British novels of the period, observing the ways in which they manifest elements of ecological imperialism and environmental racism in order to depict successful settlement. It compares these novels with fantasy fictions by Australian and New Zealand children’s authors that constitute more complicated attempts both to understand and co-exist with the natural environment. The chapter proposes that by the 1890s earlier British anxieties had dissipated in popular Australian and New Zealand fiction, in which child protagonists were newly charged with the ability to interpret and control nature.

Interventions for self-harm in children and adolescents

Background : Self-harm(SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

Objectives : To identify all randomised controlled trials of psychosocial interventions, pharmacological agents, or natural products for SHin children and adolescents, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., treatment as usual (TAU), placebo, or alternative pharmacological treatment) for children and adolescents who SH.

Search methods : For this update the Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (30 January 2015).

Selection criteria : We included randomised controlled trials comparing psychosocial or pharmacological treatments with treatment as usual, alternative treatments, or placebo or alternative pharmacological treatment in children and adolescents (up to 18 years of age) with a recent (within six months) episode of SH resulting in presentation to clinical services.

Coenzyme Q(10) and its effects in the treatment of neurodegenerative diseases

According to clinical and pre-clinical studies, oxidative stress and its consequences may be the cause or, at least, a contributing factor, to a large number of neurodegenerative diseases. These diseases include common and debilitating disorders, characterized by progressive and irreversible loss of neurons in specific regions of the brain. The most common neurodegenerative diseases are Parkinson's disease, Huntington's disease, Alzheimer's disease and amyotrophic lateral sclerosis. Coenzyme Q(10) (CoQ(10)) has been extensively studied since its discovery in 1957. It is a component of the electron transportation chain and participates in aerobic cellular respiration, generating energy in the form of adenosine triphosphate (ATP). The property of CoQ(10) to act as an antioxidant or a pro-oxidant, suggests that it also plays an important role in the modulation of redox cellular status under physiological and pathological conditions, also performing a role in the ageing process. In several animal models of neurodegenerative diseases, CoQ(10) has shown beneficial effects in reducing disease progression. However, further studies are needed to assess the outcome and effectiveness of CoQ(10) before exposing patients to unnecessary health risks at significant costs.
