Biomechanical analysis of nickel-titanium (NiTi)-cobalt-chromium (CoCr) hybrid-braided dense-mesh stents for carotid artery stenosis.

This study investigates NiTi-CoCr hybrid carotid artery stents to enhance mechanical properties over NiTi-only designs. Different configurations (24NiTi, 20NiTi-4CoCr, 16NiTi-8CoCr, and 12NiTi-12CoCr) were evaluated through radial compression and bending simulations. The 12NiTi-12CoCr stent showed the highest radial support (39.

Enhancing delirium assessment and management through nursing education interventions: A scoping review.

Aim/objective: The purpose of this scoping review was to explore the characteristics and outcomes of education interventions for nurses focused on delirium assessment and management.

Background: Delirium is a prevalent acute and reversible neuropsychiatric syndrome in hospitalized patients. Delirium can cause cognitive, psychiatric and physical impairments and result in prolonged hospital stay, increased risk of readmission and elevated morbidity and mortality rates.

Dementia and Postoperative Delirium in Surgical Hip Fracture Patients: Unveiling Contrasting Risk Factors and Implications.

Postoperative delirium is a serious complication, particularly in older adults with hip fractures. Using the 2019 American College of Surgeons National Surgical Quality Improvement Program data file, we performed multiple regression analyses to compare risk factors for postoperative delirium in hip fracture patients with and without dementia. Preoperative delirium and mobility aid use were common risk factors in both groups.

Impact of nursing interventions on discharge disposition in patients with postoperative delirium.

Purpose: To identify patient characteristics and perioperative factors associated with non-home patient discharges and the impact of current delirium nursing interventions on discharge disposition, especially non-home dispositions.

Methods: A retrospective pilot chart review was conducted using electronic health records from five networked hospitals in the Mountain West region of the US. The sample comprised 75 randomly selected patients aged 65 or older who screened positive for delirium during hospitalization.

Finite element analysis of braided dense-mesh stents for carotid artery stenosis.

When braided dense-mesh stents are used to treat carotid stenosis, the structural mechanics of vascular stents, the contact mechanics with blood vessels, and the fluid mechanics in the blood environment need to be studied in depth to reduce the damage of stents to blood vessels and the incidence of in-stent restenosis. Three types of braided stents with 8, 16, and 24 strands and laser-cut stents with the corresponding size parameters were designed, and the bending behavior of each of these types of stent, deployment, and fluid dynamic analysis of the 24-strand braided stent were simulated. The results show that the bending stress of the 8-, 16-, and 24-strand braided stents is 46.

Experimental Investigation on Interface Performance of UHPC-Strengthened NC Structure through Push-Out Tests.

Strengthening concrete structures with ultra-high performance concrete (UHPC) can both improve the bearing capacity of the original normal concrete (NC) structure and prolong the service life of the structure due to the high strength and durability of UHPC. The key to the synergistic work of the UHPC-strengthened layer and the original NC structures lies in the reliable bonding of their interfaces. In this research study, the shear performance of the UHPC-NC interface was investigated by the direct shear (push-out test) test method.

Investigation on Roles of Packing Density and Water Film Thickness in Synergistic Effects of Slag and Silica Fume.

The ternary blended cement with finer slag and silica fume (SF) could improve the packing density (PD) through the filling effect. The excess water (water more than needed for filling into voids between the cement particles) can be released to improve the fresh properties and densify the microstructure which is beneficial for improving the hardened properties. To verify the hypothesis and reveal how and why (cement + slag + SF) the ternary blends could bring such advantages, the binder pastes incorporating slag and SF with various water-to-binder ratios were produced to determine the PD experimentally.

Subsequent Pressure Injury Development in Mechanically Ventilated Critical Care Patients with Hospital-Acquired Pressure Injury: A Retrospective Cohort Study.

Objective: To identify factors associated with subsequent hospital-acquired pressure injury (HAPrI) formation among patients in surgical and cardiovascular surgical ICUs with an initial HAPrI.

Methods: Patients admitted to a level 1 trauma center and academic medical center in the Western US between 2014 and 2018 were eligible for this retrospective cohort study. Inclusion criteria were development of an HAPrI stage 2 or above, age older than 18 years, the use of mechanical ventilation for at least 24 hours, and documentation of a risk-based HAPrI-prevention plan including repositioning at least every 2 hours.

Risk factors for falls in homebound community-dwelling older adults.

Objective: To examine risk factors associated with falls among homebound community-dwelling older adults, a vulnerable population often possessing functional disabilities and chronic conditions.

Design And Sample: The study was a cross-sectional study utilizing round 6 data of the National Health and Aging Trend Study (NHATS). Descriptive statistics and multiple logistic regression analyses were conducted.

Outcomes Associated With Stage 2 Pressure Injuries Among Surgical Critical Care Patients: A Retrospective Cohort Study.

Background: Hospital-acquired pressure injuries are a serious problem among critical care patients. Although most hospital-acquired pressure injuries are stage 2 (partial-thickness skin loss with exposed dermis), no studies have examined outcomes of stage 2 pressure injuries among critical care patients.

Objectives: To examine outcomes of stage 2 hospital-acquired pressure injuries among critical care patients and identify factors associated with nonhealing stage 2 hospital-acquired pressure injuries.

Home modifications for older people with cognitive impairments: Mediation analysis of caregivers' information needs and perceptions of fall risks.

Aims And Objectives: The aims were to (a) identify how many older people with cognitive impairments are living in modified homes and (b) explore associated factors, and (c) examine the mediating effects that their caregivers' information needs and perceptions of fall risk and other factors.

Background: Older people and their informal caregivers may consider implementing home modifications as an effective strategy for fall prevention. However, there is a lack of information on which older people's homes receive modifications and the various factors associated with such modifications among community-dwelling older people with cognitive impairments.

Evidence on Fall and Injurious Fall Prevention Interventions in Acute Care Hospitals.

Falls and injurious falls are a major safety concern for patient care in acute care hospitals. Inpatient falls and injurious falls can cause extra financial burden to patients, families, and healthcare facilities. This article provides clinical implications and recommendations for adult inpatient fall and injurious fall prevention through a brief review of factors associated with falls and injurious falls and current fall prevention practices in acute care hospitals.

Outcomes Associated With Stage 1 Pressure Injuries: A Retrospective Cohort Study.

Background: Approximately half of hospital-acquired pressure injuries identified among critical care patients are stage 1. Although stage 1 injuries are common, outcomes associated with them among critical care patients have not been examined.

Objectives: To examine the outcomes of stage 1 pressure injuries among critical care patients and to identify factors associated with worsening of pressure injuries.
