Age-dependent response of murine female bone marrow cells to hyperbaric oxygen

Consequences of age on the effects of hyperbaric oxygen (HBO) on bone marrow (BM) derived stem cells and progenitors (SCPs) are largely unknown. We treated 2- and 18-month old C57BL/6 female mice by HBO. Hematopoietic stem cells and progenitors, enumerated as colony-forming units in culture, were doubled only in peripheral leukocytes and BM cells of young mice receiving HBO. In old mice colony-forming unit fibroblast numbers, a measure of mesenchymal stromal cells (MSCs) from BM, were high but unaffected by HBO. To further explore this finding, in BM-MSCs we quantified the transcripts of adipocyte early-differentiation genes peroxisome proliferator-activated receptor-γ, CCAAT/enhancer binding protein-β and fatty-acid binding protein 4; these transcripts were not affected by age or HBO. However, osteoblast gene transcripts runt-related transcription factor 2, osterix (OSX) and alkaline phosphatase (AP) were twofold to 20-fold more abundant in MSCs from old control mice relative to those of young control mice. HBO affected expression of osteoblast markers only in old MSCs (OSX gene expression was reduced by twofold and AP expression was increased threefold). Our data demonstrate the impact of aging on the response of BM SCPs to HBO and indicate the potentially different age-related benefit of HBO in wound healing and tissue remodeling

Effects of a Personalized Nurse-Led Educational Program for New Patients Receiving Oral Anticoagulant Therapy after Mechanical Heart Valve Prosthesis Implantation on Adherence to Treatment

Background: Life-long anticoagulant therapy is mandatory for patients who undergo heart valve replacement with implantation of a mechanical prosthesis. The aim of this study was to investigate the effects of a nurse-led patient educational program concerning oral anticoagulant therapy intake after heart valve replacement surgery on patients' knowledge of important parameters of anticoagulant administration. Methods: In this single-center study, 200 patients who underwent surgical implantation of a mechanical prosthesis were divided into 2 groups. The control group received the basic education concerning oral anticoagulants, while the intervention group received a personalized educational program. Results: Personalized education was correlated with a better regulation of therapeutic international normalized ratio (INR) levels and adequate knowledge among patients. Therapeutic levels of INR were achieved in 45% of the patients during the first month, 71% in the third month, and 89% in the sixth month after discharge in the intervention group, compared to 25%, 47%, and 76% in the control group, respectively. Patients' satisfaction with the information was higher in the intervention group than in the control group. The percentage of satisfaction reached 80% for the intervention group versus 37% for the patients of the control group. Conclusion: The implementation of the nurse-led educational programs was associated with improved clinical results and increased adherence to oral anticoagulant treatment. © 2021 The Korean Society for Thoracic and Cardiovascular Surgery.

The impact of ed boarding time, severity of illness, and discharge destination on outcomes of critically Ill ED patients

This aim of this study was to determine the association between emergency department (ED) boarding time, severity of illness, and outcomes for critically ill patients. This was a prospective cohort study of ED patients who met criteria for admission to the intensive care unit (ICU). Patients were divided into 2 groups: those who spent less than 6 hr in the ED prior to transfer, and those who spent 6 hr or more. The groups were compared on the basis of severity of illness, Glasgow Coma Scale score, presence of fever, admission time, and hospital survival. Factors associated with increased mortality included patients who spent 6 hr or longer in the ED, had a fever, were admitted in the evening or night, or were indirect ICU admissions. Length of time spent in the ED prior to transfer to inpatient care is one of several factors associated with increased mortality in critical care patients who were intubated in the ED.

The importance of vital signs in the triage of injured patients

Background: Vital signs are indicators of a patient presenting to an emergency department (ED). Abnormal vital signs have been associated with an increased likelihood of admission to the hospital. Physicians have long recognized the importance of vital sign observations, and vital sign measurement has proven to be useful for detecting serious diseases during triage in EDs. Methods: The study included all patients with injuries presented to the ED of a general hospital in Greece. For these patients, sex, age, cause of injury, vital signs at the time of admission to ED (systolic blood pressure, diastolic blood pressure, mean blood pressure, heart rate, and oxygen saturation), and the course of the patient (admission to hospital, discharge from ED) were recorded. The statistical analysis of data was done by the statistical package SPSS 15. It was performed using univariate regression and Spearman correlation coefficient. Results: A total of 2703 patients were registered, of which 71% were men aged 31.9 ± 0.38 years and 29% were women aged 45.7 ± 0.79 years. The main causes of injury were car accident, motor accident, pedestrian accident, fall from a height, and assault. By logistic regression, the correlation was found between mean blood pressure, systolic blood pressure, oxygen saturation, and hospitalization or discharge of the patients. Conclusions: The measurement of mean blood pressure, systolic blood pressure, and oxygen saturation of the injured patients during the admission to the ED can predict the disease course of patients.
