Rapid white matter changes in children with conduct problems during a parenting intervention

Studies report that the microstructural integrity of the uncinate fasciculus (UF; connecting the anterior temporal lobe to the orbitofrontal cortex) is abnormal in adults with psychopathy and children with conduct problems (CP), especially those with high callous-unemotional (CU) traits. However, it is unknown if these abnormalities are 'fixed' or 'reversible'. Therefore, we tested the hypothesis that a reduction in CP symptoms, following a parenting intervention, would be associated with altered microstructural integrity in the UF. Using diffusion tensor imaging tractography we studied microstructural differences (mean diffusivity (MD) and radial diffusivity (RD)) in the UF of 43 typically developing (TD) and 67 boys with CP before and after a 14-week parenting intervention. We also assessed whether clinical response in CP symptoms or CU traits explained changes in microstructure following the intervention. Prior to intervention, measures of MD and RD in the UF were increased in CP compared to TD boys. Following intervention, we found that the CP group had a significant reduction in RD and MD. Further, these microstructural changes were driven by the group of children whose CU traits improved (but not CP symptoms as hypothesized). No significant microstructural changes were observed in the TD group. Our findings suggest, for the first time, that microstructural abnormalities in the brains of children with CP may be reversible following parenting intervention.

Selective Amygdala Hypoactivity to Fear in Boys With Persistent Conduct Problems After Parent Training

BACKGROUND

Parenting interventions reduce antisocial behavior (ASB) in some children with conduct problems (CPs), but not others. Understanding the neural basis for this disparity is important because persistent ASB is associated with lifelong morbidity and places a huge burden on our health and criminal justice systems. One of the most highly replicated neural correlates of ASB is amygdala hypoactivity to another person's fear. We aimed to assess whether amygdala hypoactivity to fear in children with CPs is remediated following reduction in ASB after successful treatment and/or if it is a marker for persistent ASB.

METHODS

We conducted a prospective, case-control study of boys with CPs and typically developing (TD) boys. Both groups (ages 5-10 years) completed 2 magnetic resonance imaging sessions (18 ± 5.8 weeks apart) with ASB assessed at each visit. Participants included boys with CPs following referral to a parenting intervention group and TD boys recruited from the same schools and geographical regions. Final functional magnetic resonance imaging data were available for 36 TD boys and 57 boys with CPs. Boys with CPs were divided into those whose ASB improved (n = 27) or persisted (n = 30) following the intervention. Functional magnetic resonance imaging data assessing fear reactivity were then analyzed using a longitudinal group (TD/improving CPs/persistent CPs) × time point (pre/post) design.

RESULTS

Amygdala hypoactivity to fear was observed only in boys with CPs who had persistent ASB and was absent in those whose ASB improved following intervention.

CONCLUSIONS

Our findings suggest that amygdala hypoactivity to fear is a marker for ASB that is resistant to change following a parenting intervention and a putative target for future treatments.

Impact of Delay in Surgery on Outcome in Patients Undergoing Cardiac Revascularisation Surgery

BACKGROUND

Diagnosis of critical coronary artery disease, including after acute coronary syndrome presentation (ACS), represents an important indication for early coronary artery bypass graft (CABG) surgery. The study aims to investigate the influence of time from diagnosis to CABG on outcomes and document barriers to early revascularisation.

METHODS

All patients 18 years and older with an acute presentation due to ACS or critical coronary artery disease who were considered to require urgent inpatient cardiac surgery between January 2016-February 2019 were included in the study. The primary endpoints were 30-day all-cause mortality or readmission, 1-year all-cause mortality, all-cause readmission. The secondary endpoint was the rate of complications while waiting for surgery. The time duration between diagnostic coronary angiography and surgery was considered as the time interval.

RESULTS

Of 266 eligible patients, 251 underwent surgical revascularisation with 15 (6%) not undergoing surgery due to preoperative complications (n=12) or due to perceived prohibitively high surgical risk (n=3). The majority (85%) were male (mean age 67 years), 37% of patients had diabetes and 71% had hypertension. Non-ST elevation myocardial infarction was documented in 51% of the patients. The median time between diagnosis and inpatient CABG was 7 days (IQR 5-11). Thirty-five per cent (35%) of patients experienced complications while awaiting surgery. Of the 266 patients, 140 patients (53% - cohort 1) underwent surgery within 7 days. The cohort 1 rate of complications was lower than in cohort 2 (surgery after 7 days) (24 vs 47%, p<0.001). Moreover, 1-year mortality was less in cohort 1 (2 vs 8%, p=0.029).

CONCLUSION

In patients requiring urgent inpatient CABG, delay for more than 7 days is associated with a higher rate of in-hospital complications and worse 30 day and 12-month outcomes.

Informing the personalisation of interventions for parents of children with conduct problems: a qualitative study

BACKGROUND

Parenting programmes aim to alleviate behavioural problems in children, including conduct disorder. This study was part of a multi-phase mixed-methods project seeking to extend the reach of parenting programmes for the treatment of conduct problems through developing an evidence base to inform a personalised approach. It explored the narratives of parents of children with behavioural and conduct problems about parenting programmes to identify how such programmes could be personalised in order to extend their reach to parents and children who do not currently benefit.

METHODS

Face-to-face semi-structured interviews with a purposive sample of 42 parents, who had different experiences of parenting programmes. Interviews were conversational and informed by a topic guide. Analysis of transcripts of audio-recorded interviews drew on inductive thematic approaches and was framed largely within a phenomenological perspective.

RESULTS

Parents' accounts demonstrated three themes: 1) a personalised approach needs to include the child; 2) a supportive school matters; and, 3) the programme needs to feel personal. Parents were more likely to have a positive experience at a parenting programme, and for their child to demonstrate positive behavioural changes, when they felt their concerns were validated within the group and they also felt supported by the child's teachers. Parents whose children had been assessed prior to undertaking the programme were also more likely to perceive the programme to be beneficial, compared to parents who felt their child's individual issues were never considered.

CONCLUSIONS

Our findings point to the potential for personalised approaches to extend the reach of parenting programmes to parents and children who do not currently benefit from such programmes. Important in personalising parenting programmes is assessing children before parents are referred, to directly work with children as well as parents, and to work collaboratively with parents and children to identify which families are most suited to group support or one-to-one support and how this may change depending on circumstances.

Effect of Clinical and Treatment Factors on Survival Outcomes of Triple Negative Breast Cancer Patients

Purpose

Triple negative breast cancer (TNBC) accounts for approximately 15% of breast cancer cases and is associated with a poor prognosis. In this retrospective study of patients undergoing radiation therapy as part of their treatment, disease-free survival (DFS) and overall survival (OS) of TNBC patients were examined in relation to clinical and treatment-related factors.

Patients and Methods

The electronic records of 214 consecutive TNBC patients treated with surgery followed by radiotherapy at the Mid North Coast Cancer Institute between 2006 and 2016 were reviewed. Overall survival and DFS times were analyzed using the Kaplan-Meier method; multivariate Cox proportional hazard regression modelling was used to assess the significance of prognostic factors.

Results

The majority of tumors were T1 (51.9%), followed by T2 (39.2%) and T3 (6.1%). For the whole group, mean DFS was 106.4 (SD 48.7) months; OS 109.4 (SD 52.1) months. Radiotherapy technique, fractionation protocol and laterality were not significant factors for DFS or OS (p>0.05). However, compared to breast conservation, mastectomy was associated with poorer DFS (mean 114.2 vs 65.2 months; p<0.0001) and poorer OS (mean 115.5 vs 80.5 months; p=0.0015). The mastectomy group had fewer patients with tumor size T1 (p=0.001) and higher proportions of T3 (p=0.001) and T4 (p=0.02). On multivariate analysis, tumor size T3/T4 and nodal status N2/N3 were significant factors for reduced DFS (p=0.023 and p=0.0003 respectively). Tumor size T3/T4 was the only significant prognostic factor for reduced OS (p=0.019).

Conclusion

Advanced disease exhibited by tumor size > 5cm and positive nodal status is associated with poorer DFS in TNBC patients. Radiotherapy technique or fractionation protocol were not associated with differences in DFS or OS in our patient cohort.

Randomized controlled trial of Functional Family Therapy for offending and antisocial behavior in UK youth

BACKGROUND

Youth offending and antisocial behavior (ASB) are associated with low quality mental health and relationships and usually lead to poor adult functioning; they are very costly for society. Family interventions are effective in children but there are few reliably effective and inexpensive interventions for adolescents. Functional Family Therapy (FFT) is an evidence-based intervention but seldom tested outside the United States.

METHODS

One hundred and eleven adolescents (10-17 years of age, M = 15.0, SD = 1.63) and their families were randomized to FFT + Management As Usual (MAU) (n = 65) or to MAU (n = 46). Assessments were made at baseline 6, and 18 months after randomization and included interviews and questionnaires of parenting behaviors, conduct disorders (CDs) and offending. Parent-child interaction was directly observed and police records obtained.

TRIAL REGISTRATION

ISRCTN27650478.

RESULTS

Eighty-nine (80%) were followed-up. In both groups, there were large reductions over time in all measures of offending and antisocial behavior (e.g. primary outcome p < 0.001), but no significant changes over time in parenting behavior or the parent-child relationship. However, there were no differences between intervention and control groups at 6 or 18 months on self-reported delinquency, police records of offending, symptoms or diagnoses of CDs, parental monitoring or supervision, directly observed child negative behavior, or parental positive or negative behavior. Against predictions, the intervention group showed lower levels of directly observed child positive behavior at 18 months compared to controls.

CONCLUSIONS

In contrast to most previous trials of FFT, FFT+MAU did not lead to greater reductions in youth ASB and offending compared to MAU alone, and did not lead to improvements in parenting or the parent-child relationship. This may be because the trial was more rigorously conducted than prior studies; equally, the possibility that MAU was effective requires further research.

Impact of a parenting program in a high-risk, multi-ethnic community: the PALS trial

BACKGROUND

Parenting programs have been shown to work when delivered to motivated ethnic majority parents in demonstration projects, but comparatively little is known about their impact when delivered to high-risk, multi-ethnic populations by routine local services.

METHODS

The Primary Age Learning Skills (PALS) trial was a randomized controlled trial of an evidence-based parenting-group program that targeted the parent-child relationship and child literacy. Parents of 174 children were selected from a population of 672 5- and 6-year-olds attending four primary schools in a high-risk, ethnically diverse, inner-city area. Eighty-eight children were allocated to the Incredible Years preventive program plus a shortened six-week version of the SPOKES literacy program, delivered by local services; 86 to usual community services; 152/174 (87%) of families were successfully followed up. Parent-child relationship quality and child behavior were measured using direct observation and parent interview; child reading was assessed psychometrically.

RESULTS

Two-thirds (58/89) of those offered the parenting program attended at least one session, with similar enrollment rates across the Black African, African-Caribbean, White-British and Other ethnic groups. Mean attendance was four relationship-building sessions and one literacy-development session. Satisfaction questionnaires were completed by 43/58 starters; 93% said they were well or extremely satisfied, with equally high rates across ethnic groups. At follow-up after one year, those allocated to the intervention showed significant improvements in the parent-child relationship on observation and at interview compared to controls; effects were similar across all ethnic groups. However, child behavior problems and reading did not improve. The cost was £1,343 ($2,100) per child.

CONCLUSIONS

Programs can be organized to be engaging and effective in improving parenting among high-risk, multi-ethnic communities, which is of considerable value. To also be cost-effective in achieving child changes may require a set-up that enables parents to attend more sessions and/or an exclusive focus on children with clinically significant behavior problems.

Randomised controlled trial of parent groups for child antisocial behaviour targeting multiple risk factors: the SPOKES project

BACKGROUND

There is a pressing need for cost-effective population-based interventions to tackle early-onset antisocial behaviour. As this is determined by many factors, it would seem logical to devise interventions that address several influences while using an efficient means of delivery. The aim of this trial was to change four risk factors that predict poor outcome: ineffective parenting, conduct problems, attention deficit/hyperactivity disorder (ADHD) symptoms, and low reading ability.

METHODS

A randomised controlled trial was carried out in eight schools in London, England. Nine hundred and thirty-six (936) 6-year-old children were screened for antisocial behaviour, then parents of 112 high scorers were randomised to parenting groups held in schools or control; 109 were followed up a year later. The intervention lasted 28 weeks and was novel as it had components to address both child behaviour (through the Incredible Years programme) and child literacy (through a new 'SPOKES' programme to help parents read with their children). Fidelity of implementation was emphasised by careful training of therapists and weekly supervision. Controls received an information helpline. Assessment of conduct problems was by parent interview, parenting by direct observation and child reading by psychometric testing.

RESULTS

At follow-up parents allocated to the intervention used play, praise and rewards, and time out more often than controls, and harsh discipline less; effect sizes ranged from .31 to .59 sd (p-values .046 to .005). Compared to control children, whose behaviour didn't change, intervention children's conduct problems reduced by .52sd, (p < .001), dropping from the 80th to the 61st percentile; oppositional-defiant disorder (ODD) halved from 60% to 31% (p = .003). ADHD symptoms reduced by .44sd (p = .002), and reading age improved by six months (.36sd, p = .027). Teacher-rated behaviour didn't change. The programme cost pound2,380 ($3,800) per child.

CONCLUSIONS

Effective population-based early intervention to improve the functioning of with antisocial behaviour is practically feasible by targeting multiple risk factors and emphasising implementation fidelity.

Multicentre controlled trial of parenting groups for childhood antisocial behaviour in clinical practice

OBJECTIVE

To see whether a behaviourally based group parenting programme, delivered in regular clinical practice, is an effective treatment for antisocial behaviour in children.

DESIGN

Controlled trial with permuted block design with allocation by date of referral.

SETTING

Four local child and adolescent mental health services.

PARTICIPANTS

141 children aged 3-8 years referred with antisocial behaviour and allocated to parenting groups (90) or waiting list control (51).

INTERVENTION

Webster-Stratton basic videotape programme administered to parents of six to eight children over 13-16 weeks. This programme emphasises engagement with parental emotions, rehearsal of behavioural strategies, and parental understanding of its scientific rationale.

MAIN OUTCOME MEASURES

Semistructured parent interview and questionnaires about antisocial behaviour in children administered 5-7 months after entering trial; direct observation of parent-child interaction.

RESULTS

Referred children were highly antisocial (above the 97th centile on interview measure). Children in the intervention group showed a large reduction in antisocial behaviour; those in the waiting list group did not change (effect size between groups 1.06 SD (95% confidence interval 0.71 to 1.41), P<0.001). Parents in the intervention group increased the proportion of praise to ineffective commands they gave their children threefold, while control parents reduced it by a third (effect size between groups 0.76 (0.16 to 1.36), P=0.018). If the 31 children lost to follow up were included in an intention to treat analysis the effect size on antisocial behaviour was reduced by 16%.

CONCLUSIONS

Parenting groups effectively reduce serious antisocial behaviour in children in real life conditions. Follow up is needed to see if the children's poor prognosis is improved and criminality prevented.

Disruption and reconstruction: narrative insights into the experience of family members caring for a relative diagnosed with serious mental illness

The findings of a study investigating carers' accounts about serious mental illness occurring in their family are presented. The narrative form is a primary means of ordering, structuring, and communicating illness experiences, reflecting some of the processes that carers intend to master and understand. Psychotic episodes entail a frightening disruption that forces carers to face fundamental existential, moral, and psychological issues because they call into question the continuity of lives and life-projects. This study has explored how carers articulate the consequences of a devastating experience and turn it into a meaningful event that can in some way be incorporated into the course of their life. Two types of narrative structure were identified. In stories of restitution or reparation, the experience of the event is transformed into phenomena having meaning, occupying a place in carers' lives. In chaotic and frozen narratives, the illness remains a series of random events. The effects on coping of these two narrative types were explored, as well as gender-related themes and beliefs about mastery and control. Therapeutic implications are discussed and also possible connections to other research constructs (for example, Expressed Emotion). It is argued that the concept of illness must be approached from a systemic, multidetermined perspective that includes our narrative constructions.

Psychomotor recovery following propofol or isoflurane anaesthesia for day-care surgery

A newly developed test for the assessment of psychomotor recovery--the perceptive accuracy test (PAT)--is described. Seventy-four subjects who performed the test though that it was easy to perform and some were motivated to try it on a number of occasions. Eight persons performed the test on different days and at different periods of time; the results were consistent and reproducible. Eight more persons were then asked to do the test 4 times at 15-min intervals; no 'learning' was seen with this test. A randomized, prospective study was then performed in two groups of 15 patients, undergoing arthroscopic procedures of the knee. Anaesthesia was induced with propofol and maintained with an infusion of propofol 12 mg/kg/h for the first 15 min, followed by 8 mg/kg/h subsequently in the propofol group. In the isoflurane group, anaesthesia was also induced with propofol, but isoflurane (0.5-2%) was used to maintain anaesthesia. Alfentanil was the analgesic used in both groups of patients. Results were compared with a third group of unanaesthetised controls, who were asked to perform psychomotor tests including choice reaction time and PAT at 30-min intervals for 2.5 h. There was a significant difference (P less than 0.01) in psychomotor recovery on the PAT-200 between the propofol group and control groups, but not in the isoflurane and control groups at 30 min. Both groups had returned to baseline values at 60 min in the PAT-60 and PAT-200. The choice reaction time showed no significant difference in either group 30 min after the anaesthetic.(ABSTRACT TRUNCATED AT 250 WORDS)

Falls from trees and tree associated injuries in rural Melanesians

Falls from trees and other tree related injuries are the most common cause of trauma in some parts of rural Melanesia. A four year review of all admissions for trauma to the Provincial Hospital at Alotau, Milne Bay Province, Papua New Guinea, showed that 27% were due to falls from trees, and a further 10% were due to related injuries, such as being struck by a falling branch or a coconut. A questionnaire distributed to rural health centres showed that during the study period at least 28 villagers died from falls from trees before reaching hospital. Head and chest trauma were common causes of death. Many injured patients were boys. Forearm fractures were the most common injuries, but more serious injuries were also frequently encountered. Trees responsible for most deaths and injuries included the coconut palm, betel palm, mango, and breadfruit. There are many strategies for preventing such injuries; perhaps the most important is to stop small boys climbing tall trees. Such falls are a serious occupational hazard for many subsistence farmers.
