Revision for humeral stem loosening: a systematic review.

Introduction: Humeral loosening (HL) is an uncommon indication for revision shoulder arthroplasty. This systematic review describes patient characteristics (prosthetic type removed, reimplanted, and septic vs. aseptic loosening status), re-revision rate, and outcomes following revision surgery for a loose humeral stem.

How to avoid baseplate failure: the effect of compression and reverse shoulder arthroplasty baseplate design on implant stability.

Background: Failure to achieve fixation of the glenoid baseplate will lead to clinical failure. The fixation of the baseplate to the scapula must be able to withstand sufficient shear forces to allow bony ingrowth. The importance of compression to neutralize the forces at the baseplate-bone interface has been assumed to be critical in limiting excessive micromotion.

Increasing Stormwater Capture and Recharge Using Forecast Informed Reservoir Operations, Prado Dam.

The United States Army Corps of Engineers (USACE) operates Prado Dam in southern California for flood risk management and to capture stormwater for groundwater recharge. USACE and the Orange County Water District (OCWD) have collaborated for over 30 years to temporarily store Santa Ana River (SAR) stormflow at Prado Dam for groundwater recharge in the Orange County Groundwater Basin (Basin). USACE, OCWD, and other stakeholders are assessing Forecast Informed Reservoir Operations (FIRO) at Prado Dam as a new operational approach to capture additional supplies of SAR water for groundwater recharge without affecting Prado Dam's primary flood risk management purpose.

Pre-hospital heparin use for ST-elevation myocardial infarction is safe and improves angiographic outcomes.

Aims: This study aims to evaluate if pre-hospital heparin administration by paramedics is safe and improves clinical outcomes.

Methods And Results: Using the multicentre Victorian Cardiac Outcomes Registry, linked with state-wide ambulance records, we identified consecutive patients undergoing primary percutaneous coronary intervention for STEMI between January 2014 and December 2018. Information on thrombolysis in myocardial infarction (TIMI) flow at angiography was available in a subset of cases.

Trends in Australian inguinal hernia repair rates: a 15-year population study.

Background: An inguinal hernia is one of the most common surgical pathologies, and therefore the repair of an inguinal hernia is one of the most common general surgical procedures. The aim of this study was to assess the trend in inguinal hernia repair (IHR) rates in Australia between 2000/2001 and 2014/2015 using population data from public and private hospitals.

Methods: ICD-10 data cubes from the Australian Institute of Health and Welfare were analysed to determine the number of inguinal hernia repairs performed, open or laparoscopically, between 2000/2001 and 2014/2015 financial years.

Distributed Temperature Sensing to Measure Infiltration Rates Across a Groundwater Recharge Basin.

Managed aquifer recharge is used to augment groundwater resources and provide resiliency to water supplies threatened by prolonged droughts. It is important that recharge facilities operate at their maximum efficiency to increase the volume of water stored for future use. In this study, we evaluate the use of distributed temperature sensing (DTS) technology as a tool to measure high-resolution infiltration rates at a large-scale recharge facility.

Inpatient rehabilitation did not positively affect 6-month patient-reported outcomes after hip or knee arthroplasty.

Background: The aim of this study was to compare patient-reported outcomes 6 months after hip or knee arthroplasty in subjects who were discharged to home compared to those who attended inpatient rehabilitation.

Methods: Seven hundred and forty-eight consecutive total hip or knee replacement patients were identified from a prospective database. Preoperative and 6-month post-operative patient-reported outcome measures were recorded.

Measuring artificial recharge with fiber optic distributed temperature sensing.

Heat was used as a tracer to measure infiltration rates from a recharge basin. The propagation of diurnal oscillation of surface water temperature into the basin bed was monitored along a transect using Fiber Optic Distributed Temperature Sensing (FODTS). The propagation rate was related to downward specific discharge using standard theory of heat advection and dispersion in saturated porous media.
