Constructing a Malaysian early intervention programme for children with disabilities

This case study of a parent-initiated community project called Wings Melaka has helped improve provision of early intervention services to Malaysian children with disabilities, and their families, by making contributions specifically to the workplace at Wings Melaka, and more generally, to the much-neglected field of early intervention in Malaysia.

Effects of a daily school based physical activity intervention program on muscle development in prepubertal girls

This 12-month prospective controlled intervention evaluated the effect of a general school based physical activity program on muscle strength, physical performance and body composition in prepubertal girls. Fifty-three girls aged 7–9 years involved in a school based exercise program [40 min/day of general physical activity per school day (200 min/week)] were compared with 50 age-matched girls who participated in the general Swedish physical education curriculum (mean 60 min/week). Body composition (DXA), isokinetic peak torque (PT) of the knee extensors and flexors at 60 and 180°/s, and vertical jump height (VJH) were assessed at baseline and 12 months. The annual gain in weight was similar between the groups, but there was a greater increase in total body and regional lean mass (P < 0.05) and fat mass (P < 0.01) in the exercise group. Mean gains in knee extensor PT at 60 and 180°/s were 7.0–7.6% greater in the exercise group (P ranging <0.05–<0.001). No significant differences were detected in VJH. In conclusion, increasing school based physical education to at least 3 h/week provides a feasible strategy to enhance the development of muscle strength and lean mass in prepubertal girls.

Does stage of illness impact treatment response in bipolar disorder? Empirical treatment data and their implication for the staging model and early intervention

Objective: The staging model suggests that early stages of bipolar disorder respond better to treatments and have a more favourable prognosis. This study aims to provide empirical support for the model, and the allied construct of early intervention.

Methods: Pooled data from mania, depression, and maintenance studies of olanzapine were analyzed. Individuals were categorized as having had 0, 1–5, 6–10, or >10 prior episodes of illness, and data were analyzed across these groups.

Results: Response rates for the mania and maintenance studies ranged from 52–69% and 10–50%, respectively, for individuals with 1–5 previous episodes, and from 29–59% and 11–40% for individuals with >5 previous episodes. These rates were significantly higher for the 1–5 group on most measures of response with up to a twofold increase in the chance of responding for those with fewer previous episodes. For the depression studies, response rates were significantly higher for the 1–5 group for two measures only. In the maintenance studies, the chance of relapse to either mania or depression was reduced by 40–60% for those who had experienced 1–5 episodes or 6–10 episodes compared to the >10 episode group, respectively. This trend was statistically significant only for relapse into mania for the 1–5 episode group (p = 0.005).

Conclusion: Those individuals at the earliest stages of illness consistently had a more favourable response to treatment. This is consistent with the staging model and

Evidence and implications for early intervention in bipolar disorder

Aims: To review the evidence that supports early intervention in the treatment of bipolar disorder.

Background: Bipolar disorder is a pleomorphic condition, with varying manifestations that are determined by a number of complex factors including the ‘‘stage’’ of illness. It is consequently a notoriously difficult illness to diagnose and as a corollary is associated with lengthy delays in recognition and the initiation of suitable treatment.

Methods: A literature search was conducted using MEDLINE augmented by a manual search.

Results: Emerging neuroimaging data suggests that, in contrast to schizophrenia, where at the time of a first-episode of illness there is already discernible volume loss, in bipolar disorder, gross brain structure is relatively preserved, and it is only with recurrences that there is a sequential, but marked loss of brain volume. Recent evidence suggests that both pharmacotherapy and psychotherapy are more effective if instituted early in the course of bipolar disorder, and that with multiple episodes and disease progression there is a noticeable decline in treatment response.

Conclusions: Such data supports the notion of clinical staging, and the tailored implementation of treatments according to the stage of illness. The progressive nature of bipolar disorder further supports the concept that the first episode is a period that requires energetic broad-based treatment, with the hope that this could alter the temporal trajectory of the illness. It also raises hope that prompt treatment may be neuroprotective and that this perhaps attenuates or even prevents the neurostructural and neurocognitive changes seen to emerge with chronicity. This highlights the need for early identification at a population level and the necessity of implementing treatments and services at a stage of the illness where prognosis is optimal.

Early intervention in bipolar disorders : clinical, biochemical and neuroimaging imperatives

In the absence of clear targets for primary prevention of many psychiatric illnesses, secondary prevention becomes the most feasible therapeutic target, and is best encompassed by the concept of early intervention. This construct encompasses the goals of minimising diagnostic delay and the prompt initiation of clinically appropriate therapy. This paper develops the rationale for early intervention in bipolar disorder. Three interrelated themes are discussed; the clinical data supporting the value of prompt diagnosis and treatment in bipolar disorder, the putative biochemical mechanisms underlying the pathophysiological processes, and the parallel concept of neuroprotection, and the developing neuroimaging data that supports early intervention. Early initiation of appropriate therapy may potentially facilitate improved clinical outcomes, and further might allow the secondary prevention of the sequelae of untreated illness, which include the deleterious impact on family relationships, psychosexual and vocational development, identity and self-concept and self-stigma.

Early intervention with erythropoietin does not affect the outcome of acute kidney injury (the EARLYARF trial)

We performed a double-blind placebo-controlled trial to study whether early treatment with erythropoietin could prevent the development of acute kidney injury in patients in two general intensive care units. As a guide for choosing the patients for treatment we measured urinary levels of two biomarkers, the proximal tubular brush border enzymes γ-glutamyl transpeptidase and alkaline phosphatase. Randomization to either placebo or two doses of erythropoietin was triggered by an increase in the biomarker concentration product to levels above 46.3, with a primary outcome of relative average plasma creatinine increase from baseline over 4 to 7 days. Of 529 patients, 162 were randomized within an average of 3.5 h of a positive sample. There was no difference in the incidence of erythropoietin-specific adverse events or in the primary outcome between the placebo and treatment groups. The triggering biomarker concentration product selected patients with more severe illness and at greater risk of acute kidney injury, dialysis, or death; however, the marker elevations were transient. Early intervention with high-dose erythropoietin was safe but did not alter the outcome. Although these two urine biomarkers facilitated our early intervention, their transient increase compromised effective triaging. Further, our study showed that a composite of these two biomarkers was insufficient for risk stratification in a patient population with a heterogeneous onset of injury.

Psychological needs of adolescents in the early phase of bipolar disorder : implications for early intervention

Aim: This paper will describe the rationale for, and importance of, psychological interventions for young people early in the course of bipolar disorder.
Methods: Emerging literature in this field will be discussed in addition to describing specific clinical challenges and opportunities with this population.
Results: In order to be more developmentally appropriate for young people with bipolar disorder, eight aspects of clinical work which may require modification were identified.
Conclusions: The evidence base for the effectiveness of psychological interventions for people diagnosed with bipolar disorder is growing. However, some aspects relating to working with adults with bipolar disorder require modification to be effective in working with young people early in the course of the disorder.
