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.

Optimising a 6-plex tetanus-diphtheria-pertussis fluorescent bead-based immunoassaySmall volume assays are required for large-scale research studies and in particular paediatric trials, where multiple measures are required from a single sample. Fluorescent bead-based technology (Bioplex/Luminex) allows high through-put and simultaneous quantification of multiple analytes in a single test. This technology uses sets of microspheres, each with a unique spectral address that can be coated with a different antigen of interest.

Perioperative pediatric tonsillectomy analgesia: A single-center review of practice and cost-effectiveness analysisTonsillectomy is one of the most common pediatric surgeries and results in considerable postoperative pain. Insufficiently managed pain is costly, risks physiological and psychological consequences with multi-modal analgesia widely recommended to minimize opioid-based agents. We determined adherence to multi-modal analgesia guidelines and assessed cost-effectiveness. We undertook a cross-sectional cohort study at a tertiary pediatric institution in Perth, Western Australia, retrospectively identifying selected patients undergoing tonsillectomy over two discrete periods of 6-week duration.

Prenatal Exposure to General Anesthesia and Childhood Behavioral DeficitExposure to surgery and anesthesia in early childhood has been found to be associated with an increased risk of behavioral deficits. While the US Food and Drug Administration (FDA) has warned against prenatal exposure to anesthetic drugs, little clinical evidence exists to support this recommendation. This study evaluates the association between prenatal exposure to general anesthesia due to maternal procedures during pregnancy and neuropsychological and behavioral outcome scores at age 10.

Global maps of travel time to healthcare facilitiesAccess to healthcare is a requirement for human well-being that is constrained, in part, by the allocation of healthcare resources relative to the geographically dispersed human population. Quantifying access to care globally is challenging due to the absence of a comprehensive database of healthcare facilities. We harness major data collection efforts underway by OpenStreetMap, Google Maps and academic researchers to compile the most complete collection of facility locations to date.

PPARalpha and PPARgamma activation is associated with pleural mesothelioma invasion but therapeutic inhibition is ineffectiveMesothelioma is a cancer that typically originates in the pleura of the lungs. It rapidly invades the surrounding tissues, causing pain and shortness of breath. We compared cell lines injected either subcutaneously or intrapleurally and found that only the latter resulted in invasive and rapid growth.

BAL Inflammatory Markers Can Predict Pulmonary Exacerbations in Children With Cystic FibrosisPulmonary exacerbations in cystic fibrosis are characterized by airway inflammation and may cause irreversible lung damage. Early identification of such exacerbations may facilitate early initiation of treatment, thereby potentially reducing long-term morbidity. Research question: Is it possible to predict pulmonary exacerbations in children with cystic fibrosis, using inflammatory markers obtained from BAL fluid?

Six Months of Hybrid Closed-Loop Versus Manual Insulin Delivery With Fingerprick Blood Glucose Monitoring in Adults With Type 1 Diabetes: A Randomized, Controlled TrialTo investigate glycemic and psychosocial outcomes with hybrid closed-loop (HCL) versus user-determined insulin dosing with multiple daily injections (MDI) or insulin pump (i.e., standard therapy for most adults with type 1 diabetes). Adults with type 1 diabetes using MDI or insulin pump without continuous glucose monitoring (CGM) were randomized to 26 weeks of HCL (Medtronic 670G) or continuation of current therapy.

Poor treatment outcomes of children on highly active antiretroviral therapy: protocol for a systematic review and meta-analysisWhile access to highly active antiretroviral therapy (HAART) for children with HIV has expanded and the use of HAART has substantially reduced the morbidity and mortality of children due to HIV, poor treatment outcomes among children with HIV are still a major public health problem globally. The aim of this systematic review and meta-analysis is to quantify treatment outcomes among children with HIV.

Vascular Effects of ACE (Angiotensin-Converting Enzyme) Inhibitors and Statins in Adolescents With Type 1 DiabetesAn increased albumin-creatinine ratio within the normal range can identify adolescents at higher risk of developing adverse cardio-renal outcomes as they progress into adulthood. Utilizing a parallel randomized controlled trial and observational cohort study, we characterized the progression of vascular phenotypes throughout this important period and investigated the effect of ACE (angiotensin-converting enzyme) inhibitors and statins in high-risk adolescents.
