Cognitive behavioural therapy stabilises glycaemic control in adolescents with type 1 diabetes-Outcomes from a randomised control trial.

BACKGROUND: To compare the impact of cognitive behavioural therapy (CBT) with non-directive supportive counselling (NDC) on glycaemic control and psychological well-being in adolescents with type 1 diabetes mellitus (T1DM). MATERIALS AND METHODS: Participants aged 11 to 16 years with T1DM (duration ≥1 year) from 4 UK-based paediatric diabetes centres were randomised to receive either 6 weekly sessions of 1-to-1 CBT (n = 43) or NDC (n = 42), with 2 further sessions at 6 and 12 months. Follow-up continued for 12 months postintervention. Outcome measures included glycated haemoglobin A1c (HbA1c) and psychological scores. RESULTS: The HbA1c levels were available in 33 patients in each group for analysis. Between group difference of the overall changes in HbA1c across the study period was statically significant (P = .018). Geometric mean (range) HbA1c in the NDC group deteriorated from 68 (46-113) to 78 (48-128) mmol/mol (ie, 8.4 [6.4-12.5]% to 9.3 [6.5-13.9]%; P = .001), but was maintained in the CBT group from 72 (46-129) to 73 (51-128) mmol/mol (P = .51) (ie, 8.7 [6.4-14]% to 8.9 [6.8-13.9]%). More patients who have undergone CBT showed an improved or maintained HbA1c levels at 24 months (62.5% vs 35.5%, P = .032). Patients offered CBT with depressive scores in the lowest tertile (least depressive symptoms) showed improvement in HbA1c over time from 70 (46-102) to 67 (57-87) mmol/mol (P = .041) (ie, 8.6 [6.4-11.5]% to 8.3 [7.4-10.1]%), but not in the NDC group. The CBT showed borderline improvements in Children's Health Locus of Control (internal) scores over time compared with NDC (P = .05). The self-efficacy score showed significant improvement in both CBT (P < .001) and NDC (P = .03) groups over time. CONCLUSIONS: CBT demonstrated better maintenance of glycaemic control compared with NDC.

The impact of hyperglycemia on risk of infection and early death during induction therapy for acute lymphoblastic leukemia (ALL).

Hyperglycemia during induction chemotherapy for childhood acute lymphoblastic leukemia (ALL) has been inconsistently associated with risk of infection. We investigated the incidence of hyperglycemia during induction for childhood ALL in a retrospective cohort study of 144 patients treated on a single national protocol (UKALL2003) and explored its association with infection. All patients received dexamethasone. Overt hyperglycemia was seen in 36% and proven bacterial or fungal infection was most common in this group (OR 4.1 (1.1-15.6), P = 0.039). Both hyperglycaemia and infection were particularly common in patients with Down Syndrome.

Acute pancreatitis in children - morbidity and outcomes at 1 year.

OBJECTIVE: To establish short-term and medium-term complications 1-year postdiagnosis, of acute pancreatitis (AP) in children aged 0-14 years. DESIGN: One-year follow-up of a prospective monthly surveillance of new cases of AP in children under 15 years through the British Paediatric Surveillance Unit (BPSU) from April 2013 to April 2014. SETTING: A monthly surveillance of >3700 consultant paediatricians and paediatric surgeons in the UK and Ireland using the BPSU. PATIENTS: Children aged 0-14 years with a new diagnosis of AP. MAIN OUTCOME MEASURES: The outcomes following AP, including the incidence of complications and comorbidity at diagnosis and at 1 year. RESULTS: Of the 94 new confirmed cases of AP identified in the UK during the study period, 90 cases (96%) were included in the 1-year follow-up. 30 patients (32%) developed further episode(s) of AP. Over one-fifth of patients developed one or more major complication. At initial admission, the most common of these was pancreatic necrosis (n=8, 9%), followed by respiratory failure (n=7, 7%). Reported complications by 1 year were pseudocyst formation (n=9, 10%), diabetes requiring insulin therapy (n=4, 4%) and maldigestion (n=1, 1%). At 1-year postdiagnosis, only 59% of children made a full recovery with no acute or chronic complications or recurrent episodes of AP. Two patients died, indicating a case fatality of ~2.0%. CONCLUSIONS: AP in childhood is associated with significant short-term and medium-term complications and comorbidities including risk of recurrence in approximately a third of cases.

What change in body mass index is associated with improvement in percentage body fat in childhood obesity? A meta-regression.

OBJECTIVE: Using meta-regression this paper sets out the minimum change in body mass index-SD score (BMI-SDS) required to improve adiposity as percentage body fat for children and adolescents with obesity. DESIGN: Meta-regression. SETTING: Studies were identified as part of a large-scale systematic review of the following electronic databases: AMED, Embase, MEDLINE via OVID, Web of Science and CENTRAL via Cochrane library. PARTICIPANTS: Individuals aged 4-19 years with a diagnosis of obesity according to defined BMI thresholds. INTERVENTIONS: Studies of lifestyle treatment interventions that included dietary, physical activity and/or behavioural components with the objective of reducing obesity were included. Interventions of <2 weeks duration and those that involved surgical and/or pharmacological components (eg, bariatric surgery, drug therapy) were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: To be included in the review, studies had to report baseline and post-intervention BMI-SDS or change measurements (primary outcome measures) plus one or more of the following markers of metabolic health (secondary outcome measures): adiposity measures other than BMI; blood pressure; glucose; inflammation; insulin sensitivity/resistance; lipid profile; liver function. This paper focuses on adiposity measures only. Further papers in this series will report on other outcome measures. RESULTS: This paper explores the potential impact of BMI-SDS reduction in terms of change in percentage body fat. Thirty-nine studies reporting change in mean percentage body fat were analysed. Meta-regression demonstrated that reduction of at least 0.6 in mean BMI-SDS ensured a mean reduction of percentage body fat mass, in the sense that the associated 95% prediction interval for change in mean percentage body fat was wholly negative. CONCLUSIONS: Interventions demonstrating reductions of 0.6 BMI-SDS might be termed successful in reducing adiposity, a key purpose of weight management interventions.

Enablers and barriers to treatment adherence in heterozygous familial hypercholesterolaemia: a qualitative evidence synthesis.

OBJECTIVES: Individuals with heterozygous familial hypercholesterolaemia (FH) are at high risk of developing cardiovascular disease (CVD). This risk can be substantially reduced with lifelong pharmacological and lifestyle treatment; however, research suggests adherence is poor. We synthesised the qualitative research to identify enablers and barriers to treatment adherence. DESIGN: This study conducted a thematic synthesis of qualitative studies. DATA SOURCES: MEDLINE, Embase, PsycINFO via OVID, Cochrane library and CINAHL databases and grey literature sources were searched through September 2018. ELIGIBILITY CRITERIA: We included studies conducted in individuals with FH, and their family members, which reported primary qualitative data regarding their experiences of and beliefs about their condition and its treatment. DATA EXTRACTION AND SYNTHESIS: Quality assessment was undertaken using the Critical Appraisal Skills Programme for qualitative studies. A thematic synthesis was conducted to uncover descriptive and generate analytical themes. These findings were then used to identify enablers and barriers to treatment adherence for application in clinical practice. RESULTS: 24 papers reporting the findings of 15 population samples (264 individuals with FH and 13 of their family members) across 8 countries were included. Data captured within 20 descriptive themes were considered in relation to treatment adherence and 6 analytical themes were generated: risk assessment; perceived personal control of health; disease identity; family influence; informed decision-making; and incorporating treatment into daily life. These findings were used to identify seven enablers (eg, 'commencement of treatment from a young age') and six barriers (eg, 'incorrect and/or inadequate knowledge of treatment advice') to treatment adherence. There were insufficient data to explore if the findings differed between adults and children. CONCLUSIONS: The findings reveal several enablers and barriers to treatment adherence in individuals with FH. These could be used in clinical practice to facilitate optimal adherence to lifelong treatment thereby minimising the risk of CVD in this vulnerable population.

Identifying families' reasons for engaging or not engaging with childhood obesity services: A qualitative study.

The rise in childhood obesity in recent years has been accompanied by a number of initiatives to treat the condition. However, such interventions have often been characterised by poor levels of adherence to treatment and corresponding high attrition rates. This article presents data drawn from qualitative interviews to examine families' reasons for engaging or not engaging with child obesity services. Interviews took place with 15 families whose children attended a UK-based childhood obesity service and 17 families whose children withdrew from treatment. Our data suggested that involvement of children in the decision to attend a clinic was important in building engagement. Specialist diet and exercise advice tailored to individual family circumstance encouraged clinic engagement, but failed to engage some families who felt their personal circumstances had not been considered sufficiently. The clinic environment was viewed as not age appropriate for some children and did not match the expectations of some families. Our findings highlight the value of involving children in the decision to attend an obesity service and practitioners should, as much as possible, tailor advice to the circumstances of each family. Providing clinics for particular age groups in terms of environment and timing may enhance engagement with services.

Barriers engaging families and GPs in childhood weight management strategies.

BACKGROUND: The rapid increase in the prevalence of childhood obesity in recent years has led to inconclusive debate about the most effective way to manage the condition and the most appropriate care setting. Primary care has been suggested as a key site to identify and treat obesity in children. AIM: To identify children from general practice databases with a body mass index (BMI) categorised as 'obese', and invite them for a primary care consultation and possible referral to a specialist secondary care clinic. DESIGN AND SETTING: Targeted screening of GP practice databases for obese children in 12 general practices in Bristol, UK. METHOD: Participating GP practices searched databases for children's BMIs which were then screened by the study team to identify obese children (≥98th centile). Practices invited families of obese children to consult their GP with the potential for referral to a specialist clinic. Follow-up data was recorded with respect to: consultations; consultations about child's weight; and referrals to specialist clinic; and other referrals. RESULTS: A total of 285 letters inviting families to consult their GP were sent; 134 patients consulted their GP in the follow-up period (minimum 3 months), and 42 of these consultations discussed the child's weight. Nineteen patients received a secondary care referral and six received an alternative weight-management referral. CONCLUSION: The low take-up following the mail-out of an invitation to consult highlights the inherent difficulties of engaging families and their obese children in care pathways that facilitate long-term weight management.
