Exponential synchronization of quaternion-valued memristor-based Cohen-Grossberg neural networks with time-varying delays: norm method.

In this paper, the exponential synchronization of quaternion-valued memristor-based Cohen-Grossberg neural networks with time-varying delays is discussed. By using the differential inclusion theory and the set-valued map theory, the discontinuous quaternion-valued memristor-based Cohen-Grossberg neural networks are transformed into an uncertain system with interval parameters. A novel controller is designed to achieve the control goal.

Effects of remediation agents on rice and soil in toxic metal(loid)s contaminated paddy fields: A global meta-analysis.

Toxic metal(loid)s contamination of paddy soil is a nonnegligible issue and threatens food safety considering that it is transmitted via the soil-plant system. Applying remediation agents could effectively inhibit the soil available toxic metal(loid)s and reduce their accumulation in rice. To comprehensively quantify how remediation agents impact the accumulation of Cd/Pb/As in rice, rice growth and yield, the accumulation of available Cd/Pb/As in paddy soil, and soil characteristics, 50 peer-reviewed publications were selected for meta-analysis.

Coronal translation of the forearm, proximal capitate, and ulnar styloid predict radial inclination in distal radius fractures in older female patients.

Aims: The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI).

Methods: From posteroanterior digital radiographs of healed DRFs in 398 female patients aged 70 years or older, and 32 unfractured control wrists, the relationships of RI, quantifiably, to four linear measurements made perpendicular to reference distal radial shaft (DRS) and ulnar shaft (DUS) axes were analyzed: 1) DRS to radial aspect of ulnar head (DRS-U); 2) DUS to volar-ulnar corner of distal radius (DUS-R); 3) DRS to proximal capitate (DRS-PC); and 4) DRS to DUS (interaxis distance, IAD); and, qualitatively, to the distal ulnar fracture, and its intersection with the DUS axis.

Results: In the study (fracture) and control groups, respectively, the mean values were: RI, 17.

Short-Term Efficacy and Safety of Open Conjunctiva Ab Externo XEN45 Gel Stent Implantation in Glaucoma Patients.

Prcis: We examined the safety and efficacy of the open conjunctiva ab externo approach for XEN45 gel stent implantation. There was a significant reduction in intraocular pressure (IOP) and number of glaucoma medications at 12 months follow-up.

Purpose: This study aims to determine the safety and efficacy of the open conjunctiva ab externo approach to XEN45 stent implantation.

The Effects of Patient Resilience and Catastrophizing on Carpal Tunnel Surgical Outcomes.

Purpose: Outcomes following carpal tunnel release (CTR) are generally favorable. When patient satisfaction or symptom resolution is not as expected, understanding what factors contribute to that outcome could allow for strategies targeted at improving results. Our purpose was to determine if measurable mental health factors, specifically resilience and pain catastrophization, correlate with patients' postoperative outcomes following CTR.

Magnitude, Direction, Temporal Patterns, and Frequency of Loss of Distal Radius Fracture Reduction in Women 50 Years and Older.

Purpose: To determine the magnitude, direction, temporal patterns, and frequency of reduction loss following nonsurgical, closed treatment of distal radius fractures in women 50 years and older and correlate these observations with bone mineral density and age.

Methods: We reviewed registry data on 1,148 patients 50 years and older with distal radius fractures managed by closed reduction and cast immobilization. Radial inclination (RI), ulnar variance (UV), and radial tilt (RT) were measured immediately and at 1, 2, 3, 6, 9, and 12 weeks after reduction.

Latent class growth modeling of depression and anxiety in older adults: an 8-year follow-up of a population-based study.

Background: Depression and anxiety are common mental health conditions in the older adult population. Understanding the trajectories of these will help implement treatments and interventions.

Aims: This study aims to identify depression and anxiety trajectories in older adults, evaluate the interrelationship of these conditions, and recognize trajectory-predicting characteristics.

Nerve root sedimentation sign on MRI: A triage screen for leg dominant symptoms?

Purpose: Surgical indications for lumbar spinal stenosis are controversial, but most agree that leg dominant pain is a better predictor of success after decompression surgery. The objective of this study is to analyze the ability of the Nerve Root Sedimentation Sign (SedSign) on MRI to differentiate leg dominant symptoms from non-specific low back pain.

Methods: This was a retrospective review of 367 consecutive patients presenting with back and/or leg pain.

Four-Corner Arthrodesis With Differing Methods of Osteosynthesis: A Systematic Review.

Purpose: The purpose of this study was to compare the union rates and clinical outcomes of 4-corner arthrodesis with different methods of osteosynthesis.

Methods: A systematic review of studies published in Ovid, Medline, Embase, and PubMed was conducted. Primary studies that reported clinical and radiographic results following 4-corner arthrodesis for scapholunate advanced collapse (SLAC), scaphoid nonunion advanced collapse (SNAC), or other types of wrist arthritis in human subjects were eligible.

No decrease in incidence of arthroscopic meniscectomy in a Canadian province.

Purpose: Arthroscopic meniscectomy (APM) is the most common procedure in orthopedic surgery, despite increasing evidence questioning its benefit over conservative management for treatment of degenerative meniscal tears. The purpose of this study is to determine the epidemiology and trends of APM in Saskatchewan, a Canadian province, over a 20 year period.

Methods: Physician billing codes were used to identify patients who underwent APM in Saskatchewan between January 1, 1998 and December 31, 2017.

Trajectories of Depression and Their Predictors in a Population-Based Study of Korean Older Adults.

The aim of this study was to determine trajectories of depression in older adults and to identify predictors of membership in the different trajectory groups. A total of 3983 individuals aged 65 or older were included. Latent class growth models were used to identify trajectory groups.
