Evaluation of MindMatters Buddy Support to Secondary Schools in South West Sydney

This study assessed the outcomes of a buddy support scheme designed to increase the capacity of secondary schools to adopt a whole school approach to improving the well-being of students and to enhance uptake of MindMatters. The scheme supported schools implementing MindMatters, forming partnerships, and creating links with health services, organisations and community groups. The results showed that intervention schools were significantly more likely to ensure internal support by assigning a person responsible for MindMatters (90% vs 38%), forming a core team (79% vs 21%), reporting changes (94% vs 26%) and connectedness (100% vs 21%) and continuing MindMatters implementation (90% vs 33%) than non-intervention schools. They also reported positive outcomes in student and community participation, policy development and implementation. The results indicated the usefulness of the scheme and a plausible contribution to a greater level of sustainable changes than standard delivery of MindMatters. To assess the impact, further investigation with a larger sample is needed.     

Seroepidemiologies of Human Metapneumovirus and Respiratory Syncytial Virus in Young Children,Determined with a New Recombinant Fusion Protein Enzyme-Linked Immunosorbent Assay

We compared antibodies against human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) in children. The antibody nadirs for both viruses were at 3 to 5 months, and the majority of children were seropositive for both by 2 years. There was no significant difference in the kinetics of maternal antibody decline or seroconversion relative to the two viruses.     

Two‐ and Three‐Dimensional Transthoracic Echocardiography in the Assessment of Acquired Ascending Aortic Aneurysm to Pulmonary Artery Fistula

Aorta to pulmonary artery fistula is an uncommon and potentially fatal condition. This case is of a 48‐year‐old Caucasian male with congestive heart failure and multiple aortic valve replacement surgeries who presented with an acquired ascending aortic aneurysm to pulmonary artery fistula diagnosed using two‐dimensional transthoracic echocardiography via nonstandard imaging windows. Three‐dimensional transthoracic echocardiography using live/real time three‐dimensional color Doppler was used to assess the size of the opening of the fistula, providing additional value. This patient was surgically managed and is doing well 8 months postoperation.     

Selective Laser Sintering 3-Dimensional Printing as a Single Step Process to Prepare Amorphous Solid Dispersion Dosage Forms for Improved Solubility and Dissolution Rate

This study reports the development of ritonavir-copovidone amorphous solid dispersions (ASDs) and dosage forms thereof using selective laser sintering (SLS) 3-dimensional (3-D) printing in a single step, circumventing the post-processing steps required in common techniques employed to make ASDs. For this study, different drug loads of ritonavir with copovidone were processed at varying processing conditions to understand the impact, range, and correlation of these parameters for successful ASD formation. Further, ASDs characterized using conventional and advanced solid-state techniques including wide-angle X-ray scattering (WAXS), solid-state nuclear magnetic resonance (ssNMR), revealed the full conversion of the crystalline drug to its amorphous form as a function of laser-assisted selective fusion in a layer-by-layer manner. It was observed that an optimum combination of the powder flow properties, surface temperature, chamber temperature, laser speed, and hatch spacing was crucial for successful ASD formation, any deviations resulted in print failures or only partial amorphous conversion. Moreover, a 21-fold increase in solubility was demonstrated by the SLS 3-D printed tablets. The results confirmed that SLS 3-D printing can be used as a single-step platform for creating ASD-based pharmaceutical dosage forms with a solubility advantage.
