Background: The healthcare industry increasingly values high-quality and personalized care. Patients with heart failure (HF) receiving home health care (HHC) often experience hospitalizations due to worsening symptoms and comorbidities. Therefore, close symptom monitoring and timely intervention based on risk prediction could help HHC clinicians prevent emergency department (ED) visits and hospitalizations.

Background: Organizational readiness for change, defined as the collective preparedness of organization members to enact changes, remains understudied in implementing sepsis survivor transition-in-care protocols. Effective implementation relies on collaboration between hospital and post-acute care informants, including those who are leaders and staff. Therefore, our cross-sectional study compared organizational readiness for change among hospital and post-acute care informants.

Study Aim: This study aims to describe the transition-in-care work process for sepsis survivors going from hospitals to home health care (HHC) and identify facilitators and barriers to enable practice change and safe care transitions using a human factors and systems engineering approach.

Background: Despite high readmission risk for sepsis survivors, the transition-in-care work process from hospitals to HHC has not been described.

Methods: We analyzed semi-structured needs assessment interviews with 24 stakeholders involved in transitioning sepsis survivors from two hospitals and one affiliated HHC agency participating in the parent implementation science study, I-TRANSFER.

Article Synopsis
  • This study developed a natural language processing (NLP) system to identify social risk factors in home health care clinical notes and analyzed their link to hospitalizations or emergency department visits.
  • The research involved a retrospective cohort study of over 86,000 care episodes for nearly 66,000 patients, using expert-guided vocabulary to pinpoint relevant social risks documented in clinical notes.
  • Results showed the NLP system performed well, identifying key risk factors like Social and Physical Environment and highlighting their association with increased hospitalization and ED visits, emphasizing the importance of addressing these factors in patient care.

Objective: This study aimed to identify temporal risk factor patterns documented in home health care (HHC) clinical notes and examine their association with hospitalizations or emergency department (ED) visits.

Materials And Methods: Data for 73 350 episodes of care from one large HHC organization were analyzed using dynamic time warping and hierarchical clustering analysis to identify the temporal patterns of risk factors documented in clinical notes. The Omaha System nursing terminology represented risk factors.

This study aimed to empirically examine what effects confidence, social, and economic benefit factors have on continuous relationship orientation through the mediation of service trust, service satisfaction, and customer engagement factors in the auto maintenance and repair service sector. This study carried out a questionnaire survey with 319 customers using auto maintenance and repair service and verified hypotheses. As a result of the analysis, the confidence and social benefits of auto maintenance and repair service affected service trust, while the confidence and economic benefits affected service satisfaction.

We summarize the risk factors that may significantly contribute to racial disparities in pancreatic cancer, which is now the third leading cause of cancer deaths and projected to be second around 2030 in 12 years. For decades, the incidence rate of pancreatic cancer among Blacks has been 30% to 70% higher than other racial groups in the United States and the 5-year survival rate is approximately 5%. Diabetes and obesity have been identified as potentially predisposing factors to pancreatic cancer and both are more common among Blacks.

Background: Feasibility of dignity therapy (DT) is well established in palliative care. Evidence of its efficacy, however, has been inconsistent and may stem from DT's primary effects differing from the outcomes measured in previous studies. We proposed that DT effects were in the spiritual domain and created a new outcome measure, Dignity Impact Scale (DIS), from items previously used in a large randomized controlled trial (RCT).

Objectives: The aim of the study was to obtain objective measures indicative of gastrointestinal maturity using 3 noninvasive technologies.

Methods: Electrogastrography (EGG), abdominal near-infrared spectroscopy (NIRS), and bowel sound/acoustics (AC) monitoring were used simultaneously to obtain physiologic measures of the gastrointestinal system of 18 preterm and 5 term neonates who were tolerating enteral feedings. Measures of EGG slow wave voltage (EGG dominant power) and AC signal amplitude (AC dominant power) were obtained after spectral density analysis.

Objective: Acute transverse myelitis (ATM) is characterized by motor weakness, sensory changes, and autonomic dysfunction. However, diagnosis of ATM is based on early-stage clinical features only (and clarification of the cause of disease), which are difficult for emergency department (ED) physicians owing to low incidence rates. We performed retrospective analysis of ATM in order to provide clinical insights for early detection.

Objective: The aim of the present study was to investigate the relation between shoulder position and subclavian central venous (SCV) catheter misplacement. The shoulder position was estimated using clavicular tilt angle (CTA) values observed on anteroposterior chest X-ray images.

Methods: A retrospective case-control study was conducted on all adult patients who underwent SCV catheterization in the emergency department during a 12-month period.

Background: Previous reports demonstrated mechanisms of cardiac toxicity in acute carbon monoxide (CO) poisoning. Still, none established CO-induced cardiomyopathy (CMP) as a clinical entity. The aim of this study is to investigate CO-induced CMP in patients with acute CO poisoning in terms of its epidemiology, clinical characteristics, and prognosis.

Background: Fractional exhaled nitric oxide (FENO) is nitric oxide (NO) in the lower airway measured by oral exhalation. FENO can be a useful non-invasive marker for asthma. Paraquat-mediated lung injury can be reflective of an ROS-induced lung injury.

Marine microalga, Scenedesmus sp., which is known to be suitable for biodiesel production because of its high lipid content, was subjected to the conventional Folch method of lipid extraction combined with high-pressure homogenization pretreatment process at 1200 psi and 35°C. Algal lipid yield was about 24.

The effect of ultrasonic extraction on extraction yields, cytotoxicity, and anticancer activity of Spirulina maxima was investigated in this study. Optimal extraction conditions were determined as 60 kHz frequency at 60°C for 30 min with 120 W intensity, which resulted in 19.3% of extraction yields and 19.

We compared two 16-electrode electrical impedance tomography (EIT) current patterns on their ability to reconstruct and quantify small amounts of bleeding inside a neonatal human head using both simulated and phantom data. The current patterns used were an adjacent injection RING pattern (with electrodes located equidistantly on the equator of a sphere) and an EEG current pattern based on the 10-20 EEG electrode layout. Structures mimicking electrically important structures in the infant skull were included in a spherical numerical forward model and their effects on reconstructions were determined.

The electrical impedance tomography (EIT) image reconstruction problem is ill posed and spatially variant. Because of the problem's ill-posed nature, small amounts of measurement noise can corrupt reconstructed images. The problem must be regularized to reduce image artifacts.

Electrical impedance tomography (EIT) is particularly well-suited to applications where its portability, rapid acquisition speed and sensitivity give it a practical advantage over other monitoring or imaging systems. An EIT system's patient interface can potentially be adapted to match the target environment, and thereby increase its utility. It may thus be appropriate to use different electrode positions from those conventionally used in EIT in these cases.
