Do Gerontology Nurse Specialists Make a Difference in Hospitalization of Long‐Term Care Residents? Results of a Randomized Comparison Trial

Residents of long‐term care facilities have highly complex care needs and quality of care is of international concern. Maintaining resident wellness through proactive assessment and early intervention is key to decreasing the need for acute hospitalization. The Residential Aged Care Integration Program (RACIP) is a quality improvement intervention to support residential aged care staff and includes on‐site support, education, clinical coaching, and care coordination provided by gerontology nurse specialists (GNSs) employed by a large district health board. The effect of the outreach program was evaluated through a randomized comparison of hospitalization 1 year before and after program implementation. The sample included 29 intervention facilities (1,425 residents) and 25 comparison facilities (1,128 residents) receiving usual care. Acute hospitalization rate unexpectedly increased for both groups after program implementation, although the rate of increase was significantly less for the intervention facilities. The hospitalization rate after the intervention increased 59% for the comparison group and 16% for the intervention group (rate ratio (RR) = 0.73, 95% confidence interval (CI) = 0.61–0.86, P < .001). Subgroup analysis showed a significantly lower rate change for those admitted for medical reasons for the intervention group (13% increase) than the comparison group (69% increase) (RR = 0.67, 95% CI = 0.56–0.82, P < .001). Conversely, there was no significant difference in the RR for surgical admissions between the intervention and comparison groups (RR = 1.0, 95% CI = 0.68–1.46, P = .99). The integration of GNS expertise through the RACIP intervention may be one approach to support staff to provide optimal care and potentially improve resident health.     

Murine monoclonal antibody MB-2D10 recognizes Rh-related glycoproteins in the human red cell membrane

The human red cell membrane components reacting with monoclonal antibody MB-2D10 were examined by immunoblotting. The antibody bound to a diffusely staining band extending from Mr 30,000 up to the high-molecular-weight region of the gel in normal membranes and in Rhnull U + membranes, but not in Rhnull U - membranes. Treatment of normal red cells with an endoglycosidase F-containing preparation destroyed the epitope recognized by MB-2D10. The reactivity of the antibody with purified preparations of Rh-related glycoproteins D30 polypeptide, D50 polypeptide, R6A32 polypeptide, and R6A45 polypeptide was also examined. Only the purified R6A45 and D50 components reacted with MB-2D10. These results show that MB-2D10 recognizes a carbohydrate-dependent epitope on the R6A45 and D50 group of Rh-related polypeptides. The results also suggest the possibility that the U antigen arises from interaction between glycophorin B and the Rh-related components D50 and R6A45.     

Pharmacokinetics and Bioavailability of Plant Lignan 7-Hydroxymatairesinol and Effects on Serum Enterolactone and Clinical Symptoms in Postmenopausal Women: A Single-Blinded,Parallel, Dose-Comparison Study

Objective: 7-Hydroxymaitairesinol (7-HMR) is a naturally occurring plant lignan found in whole grains and the Norway spruce (Piciea abies). The purpose of this study was to evaluate the bioavailability of a proprietary 7-HMR product (HMRlignan, Linnea SA, Locarno, Switzerland) through measurement of lignan metabolites and metabolic precursors.

Methods: A single-blind, parallel, pharmacokinetic and dose-comparison study was conducted on 22 postmenopausal females not receiving hormone replacement therapy. Subjects were enrolled in either a 36 mg/d (low-dose) or 72 mg/d dose (high-dose) regimen for 8 weeks. Primary measured outcomes included plasma levels of 7-HMR and enterolactone (ENL), and single-dose pharmacokinetic analysis was performed on a subset of subjects in the low-dose group. Safety data and adverse event reports were collected as well as data on hot flash frequency and severity.

Results: Pharmacokinetic studies demonstrated 7-HMR C _max = 757.08 ng/ml at 1 hour and ENL C _max = 4.8 ng/ml at 24 hours. From baseline to week 8, plasma 7-HMR levels increased by 191% in the low-dose group (p < 0.01) and by 1238% in the high-dose group (p < 0.05). Plasma ENL levels consistently increased as much as 157% from baseline in the low-dose group and 137% in the high-dose group. Additionally, the mean number of weekly hot flashes decreased by 50%, from 28.0/week to 14.3/week (p < 0.05) in the high-dose group. No significant safety issues were identified in this study.

Conclusion: The results demonstrate that HMRlignan is quickly absorbed into the plasma and is metabolized to ENL in healthy postmenopausal women. Clinically, the data demonstrate a statistically significant improvement in hot flash frequency. Doses up to 72 mg/d HMRlignan for 8 weeks were safe and well tolerated in this population.     

Incorporating Antiracism Coursework into a Cultural Competency Curriculum

Creating a socially conscious educational environment is an imperative if health care practitioners are to have a significant impact on health inequities. The effects of practitioner bias, prejudice, and discrimination on health and health outcomes have been well documented in the literature. Individuals being trained to provide health care will be entering into an increasingly diverse world and must be equipped with the appropriate knowledge and skills in order to meet the needs of those seeking their care. Cultural competency training in medical education has evolved over the past 15 years since the Institute of Medicine's 2002 report, Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care. As research on the effectiveness of this training has emerged, several authors have called for the integration of antiracism training into the cultural competency curriculum, but few have found effective ways of doing so. This article describes the approach of one midwifery program in order to inform clinical education programs across the spectrum of health care practitioners.
