Stratified Medicine Paediatrics: Cell free DNA and serial tumour sequencing identifies subtype specific cancer evolution and epigenetic states.

We profiled a large heterogenous cohort of matched diagnostic-relapse tumour tissue and paired plasma-derived cell free DNA (cfDNA) from patients with relapsed and progressive solid tumours of childhood. Tissue and cfDNA sequencing results were concordant, with a wider spectrum of mutant alleles and higher degree of intra-tumour heterogeneity captured by the latter, if sufficient circulating tumour-derived DNA (ctDNA) was present. Serial tumour sequencing identified putative drivers of relapse, with alterations in epigenetic drivers being a common feature.

Clinicopathological Analysis of a European Cohort of MYOD1 Mutant Rhabdomyosarcomas in Children and Young Adults.

Background: Patients with PAX3/7-FOXO1 fusion-negative rhabdomyosarcomas (fnRMS) harbouring the rare L122R MYOD1 mutation have significantly poorer prognosis than other fnRMS. We undertook a detailed clinicopathological evaluation of a cohort of patients with MYOD1 mutated fnRMS in order to improve risk stratification and treatment options.

Procedure: Histological, mutational and clinical data from a cohort of patients with MYOD1 mutant RMS treated in Europe were analysed.

Frontline and Relapsed Rhabdomyosarcoma (FaR-RMS) Clinical Trial: A Report from the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG).

The Frontline and Relapsed Rhabdomyosarcoma (FaR-RMS) clinical trial is an overarching, multinational study for children and adults with rhabdomyosarcoma (RMS). The trial, developed by the European Soft Tissue Sarcoma Study Group (EpSSG), incorporates multiple different research questions within a multistage design with a focus on (i) novel regimens for poor prognostic subgroups, (ii) optimal duration of maintenance chemotherapy, and (iii) optimal use of radiotherapy for local control and widespread metastatic disease. Additional sub-studies focusing on biological risk stratification, use of imaging modalities, including [F]FDG PET-CT and diffusion-weighted MRI imaging (DWI) as prognostic markers, and impact of therapy on quality of life are described.

Quantitative diffusion-weighted MRI response assessment in rhabdomyosarcoma: an international retrospective study on behalf of the European paediatric Soft tissue sarcoma Study Group Imaging Committee.

Objective: To investigate the feasibility of diffusion-weighted magnetic resonance imaging (DW-MRI) as a predictive imaging marker after neoadjuvant chemotherapy in patients with rhabdomyosarcoma.

Material And Methods: We performed a multicenter retrospective study including pediatric, adolescent and young adult patients with rhabdomyosarcoma, Intergroup Rhabdomyosarcoma Study group III/IV, treated according to the European paediatric Soft tissue sarcoma Study Group (EpSSG) RMS2005 or MTS2008 studies. DW-MRI was performed according to institutional protocols.

Patient Reported Outcomes and Measures in Children with Rhabdomyosarcoma.

In addition to optimising survival of children with rhabdomyosarcoma (RMS), more attention is now focused on improving their quality of life (QOL) and reducing symptoms during treatment, palliative care or into long-term survivorship. QOL and ongoing symptoms related to the disease and its treatment are outcomes that should ideally be patient-reported (patient-reported outcomes, PROs) and can be assessed using patient-reported outcome measures (PROMS). This commentary aims to encourage PRO and PROM use in RMS by informing professionals in the field of available PROMs for utilisation in paediatric RMS and provide considerations for future use in research and clinical practice.

A Novel ABCA4 Mutation Associated with a Late-Onset Stargardt Disease Phenotype: A Hypomorphic Allele?

Background: Stargardt disease (STGD) is the most common juvenile hereditary macular dystrophy. In the majority of cases, the diagnosis is made prior to 20 years of age and usually leads to loss of central vision. Late-onset STGD affects a smaller number of patients.

Bronchiectasis following treatment for high-risk neuroblastoma: A case series.

High-risk (HR) neuroblastoma remains a very challenging disease to treat and long-term cure is only possible with intensive, multimodal treatment including chemotherapy, high-dose therapy, radiotherapy, surgery, and immunotherapy. As a result, treatment-related morbidity and late effects are common in survivors. This report outlines a case series of six patients who developed a chronic productive cough following treatment for HR neuroblastoma.

Autoinflammatory retinopathy in chronic infantile neurological cutaneous and articular (CINCA) syndrome.

Chronic infantile neurological cutaneous and articular (CINCA) syndrome is a rare autosomal dominant autoinflammatory disease. We report the cases of monozygotic twins with CINCA syndrome whose predominant ocular manifestation was inflammatory rod-cone retinal dystrophy. Atypically, there were significant differences between twins in phenotype severity, suggestive of epigenetic differences and/or involvement of environmental factors.

Plasma Inflammatory Factors Are Associated with Anxiety, Depression, and Cognitive Problems in Adults with and without Methamphetamine Dependence: An Exploratory Protein Array Study.

Objectives: It is hypothesized that immune factors influence addictive behaviors and contribute to relapse. The primary study objectives were to (1) compare neuropsychiatric symptoms across adults with active methamphetamine (MA) dependence, in early remission from MA dependence, and with no history of substance dependence, (2) determine whether active or recent MA dependence affects the expression of immune factors, and (3) evaluate the association between immune factor levels and neuropsychiatric symptoms.

Methods: A cross-sectional study was conducted using between group comparisons and regression analyses to investigate associations among variables.

Age-related macular degeneration in ethnically diverse Australia: Melbourne Collaborative Cohort Study.

Purpose: To determine and compare the prevalence of age-related macular degeneration (AMD) in older Australians of Anglo-Celtic and Southern European origin.

Methods: A total of 21,132 participants of the Melbourne Collaborative Cohort Study, aged 47-86 years, were assessed for AMD in 2003-2007 with non-mydriatic fundus photography. Of these, 14% were born in Southern Europe (Greece, Italy or Malta), with the remaining 86% of Anglo-Celtic origin, born in Australia, the United Kingdom or New Zealand.

Acute myeloid leukaemia after treatment for acute lymphoblastic leukaemia in girl with Bloom syndrome.

Bloom syndrome (BS) is an inherited genomic instability disorder caused by disruption of the BLM helicase and confers an extreme cancer predisposition. Here we report on a girl with BS who developed acute lymphoblastic leukaemia (ALL) at age nine, and treatment-related acute myeloid leukaemia (t-AML) aged 12. She was compound heterozygous for the novel BLM frameshift deletion c.

The prevalence and risk factors of epiretinal membranes: the Melbourne Collaborative Cohort Study.

Purpose: To determine the prevalence of epiretinal membranes (ERMs) in Melbourne, Australia and its risk factors in this population.

Methods: The Melbourne Collaborative Cohort Study is a prospective study investigating the role of diet and life style in the causation of common chronic diseases. Eighty-six percent of participants were of Northern European origin born in Australia or United Kingdom and 14% were migrants from Greece or Italy (Southern European origin).

Can genetic associations change with age? CFH and age-related macular degeneration.

Genetic variation in the gene encoding complement factor H (CFH) on chromosome 1q31 has repeatedly been associated with an increased risk of age-related macular degeneration (AMD); however, previous studies have had inadequate numbers of participants across a sufficiently wide age range to determine whether the association varies by age. We conducted a genetic case-control study using data from 2294 cases and 2294 controls selected from the Melbourne Collaborative Cohort Study, matched on age, sex and region of origin. Four consistently replicated CFH single-nucleotide polymorphisms (SNPs) were genotyped: rs1061170 (Y402H), rs2274700, rs393955 and rs800292; their relationship with AMD prevalence was determined across the age range 48-86.

20/20--Alcohol and age-related macular degeneration: the Melbourne Collaborative Cohort Study.

Little evidence exists regarding associations between age-related macular degeneration (AMD) and moderate alcohol consumption, patterns of consumption, or different types of alcoholic beverage. The authors examined associations between AMD prevalence and alcohol intake using 20,963 participants from the Melbourne Collaborative Cohort Study aged 40-69 years at baseline (1990-1994). Participants' alcohol consumption was determined from a structured interview at baseline.

Apolipoprotein E gene associations in age-related macular degeneration: the Melbourne Collaborative Cohort Study.

The apolipoprotein E gene (APOE) has been found to be associated with age-related macular degeneration (AMD). Reported associations have been questioned, as they are opposite those for Alzheimer's disease and cardiovascular disease. The authors examined associations between APOE genotype and AMD using a case-control study (2,287 cases and 2,287 controls individually matched on age, sex, and country of origin) nested within Melbourne Collaborative Cohort Study participants aged 48-86 years at AMD detection.

Abdominal obesity and age-related macular degeneration.

Evidence for an association between age-related macular degeneration (AMD) and obesity is inconsistent. The authors examined associations between adiposity and AMD prevalence using 21,287 participants from the Melbourne Collaborative Cohort Study aged 40-69 years at baseline (1990-1994). For men, each increase of 0.

Management of bronchiolitis.

Bronchiolitis is the commonest cause of hospital admission in infancy. Severity varies from mild and self-limiting through to respiratory failure requiring intensive care and ventilation. Many viruses cause bronchiolitis, the commonest being respiratory syncytial virus (RSV).
