Characterization of Rice Yield Based on Biomass and SPAD-Based Leaf Nitrogen for Large Genotype Plots.

The use of Unmanned Aerial Vehicle (UAV) images for biomass and nitrogen estimation offers multiple opportunities for improving rice yields. UAV images provide detailed, high-resolution visual information about vegetation properties, enabling the identification of phenotypic characteristics for selecting the best varieties, improving yield predictions, and supporting ecosystem monitoring and conservation efforts. In this study, an analysis of biomass and nitrogen is conducted on 59 rice plots selected at random from a more extensive trial comprising 400 rice genotypes.

Geometry Regularized Autoencoders.

A fundamental task in data exploration is to extract low dimensional representations that capture intrinsic geometry in data, especially for faithfully visualizing data in two or three dimensions. Common approaches use kernel methods for manifold learning. However, these methods typically only provide an embedding of the input data and cannot extend naturally to new data points.

Cost Disclosure of Surgeon "Scorecards": Effects on Operating Room Costs for Total Hip and Knee Arthroplasty.

Rising health care costs, coupled with an emphasis on cost containment, continue to gain importance. Surgeon cost scorecards developed to track case-based expenditures can help surgeons compare themselves with their peers and identify areas of potential quality improvement. We sought to investigate what effect surgeon scorecards had on operating room (OR) costs in orthopedic surgery.

Short-Term Follow-Up of Patellar Component Revision in Patients With Isolated Patellar Component Loosening.

Background: The etiology of patellar component loosening can be multifactorial, including component malposition, trauma, infection, and poor implant design. These cases may be managed with isolated patellar component revision or simultaneous patellar component with femoral and/or tibial component revision. Isolated patellar revision in the setting of aseptic loosening historically has had limited success with high rates of repeat revision.

Impact of Resident Training Level on Radiation Exposure During Fixation of Proximal Femur Fractures.

Objective: To identify whether residents are at greater risk of radiation exposure from intraoperative fluoroscopy while earlier in their training and during more complex procedures.

Methods: We analyzed 852 extracapsular proximal femur fracture fixation cases. We compared fluoroscopy times by various levels of resident training, fracture type, and implant used.

A Simple Protocol to Stratify Pulmonary Risk Reduces Complications After Total Joint Arthroplasty.

Background: Pulmonary complications after total joint arthroplasty are a burden to patients and the healthcare system. The aim of this study is to demonstrate the effectiveness of a pulmonary screening questionnaire and intervention protocol developed at our institution to prevent pulmonary complications.

Methods: Between 2010 and 2015, 7658 consecutive total joint arthroplasty patients at our institution were reviewed.

A Proactive Approach to High Risk Delirium Patients Undergoing Total Joint Arthroplasty.

Background: Delirium is a common complication among elderly patients undergoing total joint arthroplasty (TJA). Its incidence has been reported from 4% to 53%. The Centers for Medicare and Medicaid Services consider delirium following TJA a "never-event.

The Direct Anterior Approach Does Not Increase Return to Function Following Hemiarthroplasty for Femoral Neck Fracture.

The purpose of this study was to evaluate functional outcomes for hemiarthroplasty using a direct anterior approach or a direct lateral approach for femoral neck fracture. This retrospective review used data collected from a single institution between 2006 and 2016. Eighty-five and 75 consecutive patients who underwent hemiarthroplasty via a direct anterior approach and a direct lateral approach, respectively, met inclusion criteria.

Is There Still a Role for Irrigation and Debridement With Liner Exchange in Acute Periprosthetic Total Knee Infection?

Background: Periprosthetic joint infection (PJI) is an important cause of failure in total knee arthroplasty. Irrigation and debridement including liner exchange (I&D/L) success rates have varied for acute PJI. The purpose of this study is to present results of a specific protocol for I&D/L with retention of total knee arthroplasty components.

Analysis of the LRRK2 p.G2019S mutation in Colombian Parkinson's Disease Patients.

Introduction: Mutations in the leucine-rich repeat kinase 2 gene (LRRK2 or Dardarin) are considered to be a common cause of autosomal dominant and sporadic Parkinson´s disease, but the prevalence of these mutations varies among populations.

Objective: to analyzed the frequency of the LRRK2 p.G2019S mutation (c.

Theory of Inpatient Circadian Care (TICC): A Proposal for a Middle-Range Theory.

The circadian system controls the daily rhythms of a variety of physiological processes. Most organisms show physiological, metabolic and behavioral rhythms that are coupled to environmental signals. In humans, the main synchronizer is the light/dark cycle, although non-photic cues such as food availability, noise, and work schedules are also involved.

Negative pleural suction in thoracic trauma patients: A randomized controlled trial.

Background: The study aimed to establish the benefits of using chest tubes with negative pleural suction against trapped water in patients with penetrating or blunt chest trauma who underwent tube thoracostomy, in terms of the incidence of complications, such as persistent air leak, clotted hemothorax, empyema, and duration of stay.

Methods: Patients who underwent tube thoracostomy because of traumatic pneumothorax, hemothorax, or hemopneumothorax were randomly assigned into one of two groups: in Group 1, the three-bottle drainage system was connected to a negative suction; in Group 2, no suction was given. Patients who required mechanical ventilation or emergency surgery (thoracotomy or thoracoscopy) either at the time of admission to the institution or immediately after the tube thoracostomy, patients who had histories of thoracic procedures or chronic pulmonary diseases (chronic obstructive pulmonary disease, diffuse interstitial lung disease), and patients with multiple injuries with severe traumatic brain injury and a Glasgow Coma Scale (GCS) score less than 8 of 15 were excluded from the study.
