Pathobiologic Mechanisms of Neurodegeneration in Osteopetrosis Derived From Structural and Functional Analysis of 14 ClC-7 MutantsClC-7 is a chloride-proton antiporter of the CLC protein family. In complex with its accessory protein Ostm-1, ClC-7 localizes to lysosomes and to the osteoclasts' ruffled border, where it plays a critical role in acidifying the resorption lacuna during bone resorption. Gene inactivation in mice causes severe osteopetrosis, neurodegeneration, and lysosomal storage disease. Mutations in the human CLCN7 gene are associated with diverse forms of osteopetrosis.

Mapping malaria by sharing spatial information between incidence and prevalence data setsAs malaria incidence decreases and more countries move towards elimination, maps of malaria risk in low-prevalence areas are increasingly needed. For low-burden areas, disaggregation regression models have been developed to estimate risk at high spatial resolution from routine surveillance reports aggregated by administrative unit polygons.

Malignant Melanoma in Children and Adolescents Treated in Pediatric Oncology Centers: An Australian and New Zealand Children’s Oncology Group (ANZCHOG) StudyUnlike adults, malignant melanoma in children and adolescents is rare. In adult melanoma, significant progress in understanding tumor biology and new treatments, including targeted therapies and immunotherapy have markedly improved overall survival. In sharp contrast, there is a paucity of data on the biology and clinical behavior of pediatric melanoma. We report a national case series of all pediatric and adolescent malignant melanoma presenting to ANZCHOG Childhood Cancer Centers in Australia and New Zealand.

Reduced socs1 expression in lung fibroblasts from patients with ipf is not mediated by promoter methylation or mir155The interleukin (IL)-6 family of cytokines and exaggerated signal transducer and activator of transcription (STAT)3 signaling is implicated in idiopathic pulmonary fibrosis (IPF) pathogenesis, but the mechanisms regulating STAT3 expression and function are unknown. Suppressor of cytokine signaling (SOCS)1 and SOCS3 block STAT3, and low SOCS1 levels have been reported in IPF fibroblasts and shown to facilitate collagen production. Fibroblasts and lung tissue from IPF patients and controls were used to examine the mechanisms underlying SOCS1 down-regulation in IPF.

Additional Insulin is Required in Both the Early and Late Postprandial Periods for Meals High in Protein and Fat: A Randomised TrialThe pattern and quantity of insulin required for high protein high fat (HPHF) meals is not well understood. This study aimed to determine the amount and delivery pattern of insulin required to maintain euglycaemia for five hours after consuming a HPHF meal compared to a low protein low fat (LPLF) meal.

Barriers and motivators for preschoolers playing and walking with their dog: Results from qualitative researchA large proportion of preschoolers do not meet the recommended three hours of daily physical activity. A potential source of daily physical activity could be that provided via the family dog. This qualitative study aimed to explore the barriers and motivators to preschoolers playing with their dog and participating in family dog walks.

Targeted Teacher Education to Improve Primary Preservice Teachers’ Knowledge and Understanding of UV and Effective Sun Protection Measures for ChildrenTeachers are responsible for children at school during peak ultraviolet (UV) times of the day. It is paramount that teachers have knowledge and understanding of UV to effectively protect themselves and their students. The aim of this pilot study was to investigate the effect of a short intervention on preservice teachers’ sun protective behaviours, knowledge and perceived skill to teach sun safety.

Severe congenital cutis laxa: Identification of novel homozygous LOX gene variants in two familiesWe report three babies from two families with a severe lethal form of congenital cutis laxa. All three had redundant and doughy-textured skin and two siblings from one family had facial dysmorphism. Echocardiograms showed thickened and poorly contractile hearts, arterial dilatation and tortuosity. Post-mortem examination in two of the babies further revealed widespread ectasia and tortuosity of medium and large sized arteries, myocardial hypertrophy, rib and skull fractures.

Justice capital: A model for reconciling structural and agentic determinants of desistanceThe emerging literature on desistance (and recovery from addictions) has focused on key life-course transitions that can be characterised as the need for jobs (meaningful activities), friends (transitioning to pro-social) and houses (a home free from threat). The term ‘recovery capital’ is used to characterise personal, social and community resources an individual can draw upon to support their recovery, partly bridging agentic (personal) and structural (community) factors.

The familial risk of infection-related hospitalization in children: A population-based sibling studyTo assess the risk of severe childhood infections within families, we conducted a sibling analysis in a population-based cohort study with genealogical linkage. We investigated the sibling risk of hospitalization with common infections, a marker of severity. We hypothesized that having siblings hospitalized for infection would increase the proband's risk of admission with infection.
