Empowerment of frail institutionalized older people for self-care: from administrators' and staff caregivers' perspectives.

PURPOSE: To investigate the perspectives of administrators and staff caregivers in empowering older people living in long-term care facilities to improve self-care abilities. METHODS: A phenomenology research design was employed to generate data. The purposive sampling method was used to recruit administrator (n = 7) and staff caregiver groups (n =11). Data were collected via face-to-face interviews, observations, and daily recording. The data were then analyzed via content analysis. RESULTS: The results showed that two elements were of critical importance: professional supports and teamwork. The following professional supports activities were found of positive impacts: allowing residents to perform self-care and improving their mood status. The teamwork was developed via a partnership between staff and family caregivers, and preventing and resolving conflicts in the workplace. CONCLUSION: The teamwork could not only reduce the burdens of both staff and family caregivers, but also improve the quality of life and the capacity of older residents. Thus, residents, staffs and family caregivers should work as a team and support older people to perform self-care.

Effectiveness of Applying Evidence-based Guidelines for Nurses Training on Nasogastric Tube Care.

BACKGROUND: This study formulated clinical guidelines for assessing nasogastric tube placement and for health education guidance according to evidence-based recommendations. METHOD: This study used a single group, pre- and postintervention design. Purposive sampling was used to recruit participants from nursing institutions in Taiwan. RESULTS: Sixty-two individuals in charge of nursing institutions were recruited to participate in the in-service training program. Statistically significant differences were observed in the four major items in the self-directed learning readiness scale (t = 3.85, p < .00; t = 3.99, p < .00; t = 2.94, p < .01; t = 4.13, p < .00). With regard to program satisfaction, the mean score was 4.88 to 4.9 points. The mean score for teaching satisfaction was 4.94 to 4.9 points. Furthermore, the participants scored more than 80 points in the online course test and the nasogastric tube placement skill. CONCLUSION: The individuals in-charge are expected to be willing to apply and promote methods of literature collation and recommendation in their respective institutions.

Stimulatory effects of Porphyromonas gingivalis GroEL protein on interleukin-6 and interleukin-8 in human osteoblasts.

BACKGROUND/PURPOSE: Porphyromonas gingivalis is an oral pathogen associated with periodontal diseases. P. gingivalis GroEL protein is a stimulator of inflammatory cytokines in macrophages. This study inspected effects of P. gingivalis GroEL protein on production of interleukin (IL)-6 and IL-8 by human osteoblasts. METHODS: Viability of GroEL-treated osteoblasts was analyzed with 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide. Secretion of IL-6 and IL-8 was analyzed using the enzyme-linked immunosorbent assay. Levels of mRNA were analyzed using the reverse transcription and real-time polymerase chain reaction. The antioxidant (curcumin), the p38 mitogen-activated protein kinase (MAPK) inhibitor (SB203580) and the c-Jun N-terminal kinase (JNK) inhibitor (SP600125) were employed to elucidate possible signaling pathways involved. RESULTS: Treatment with GroEL did not affect morphology and viability of osteoblasts. GroEL significantly induced the secretion of IL-6 and IL-8 by osteoblasts in a concentration-dependent pattern. Moreover, the mRNA levels of IL-6 and IL-8 were stimulated by GroEL. The application of SP600125 (10 µM) significantly suppressed the induction of IL-6 and IL-8 by GroEL-treated cells. However, curcumin (20 µM) and SB203580 (20 µM) only down-regulated the stimulatory effects of GroEL on IL-6. CONCLUSION: GroEL protein stimulated the inflammatory reaction of osteoblasts, probably through the activation of p38 MAPK or JNK pathway. The findings suggest that P. gingivalis GroEL may influence the immune functions of osteoblasts and endanger the periodontal health.

Association between monocyte chemoattractant protein-1 -2518 A/G gene polymorphism and the outcome of the nonsurgical periodontal treatment.

BACKGROUND/PURPOSE: Elevated monocyte chemoattractant protein-1 (MCP-1) is related to severe periodontal destruction. Furthermore, MCP-1 -2518 A/G gene polymorphism affects MCP-1 after inflammatory stimuli. This study analyzed the association between MCP-1 -2518 gene polymorphism and the outcome of nonsurgical periodontal treatment. METHODS: Forty periodontal patients were recruited and MCP-1 -2518 A/G gene polymorphisms were analyzed using polymerase chain reaction-restriction fragment length polymorphism assay. The clinical periodontal parameters, including probing depth (PD), clinical attachment level (CAL), gingival index (GI), bleeding index (BI) and plaque index (PI), were recorded before and six weeks after nonsurgical periodontal therapy. Patients were divided into chronic periodontitis (CP) or aggressive periodontitis (AP). Multiple linear regression analysis was performed to investigate certain predictors of the therapy outcome. RESULTS: The frequency of MCP-1 -2518 genotype-positive (carrying allele G) was 42.5%. Poor treatment outcome in PD, GI and BI improvement could be predicted with MCP-1 -2518 A/G genotype and aggressive periodontitis status as the predictor variables. In contrast, MCP-1 -2518 A/A genotype and aggressive periodontitis status could predict better treatment response in PD and BI improvement. However, MCP-1 -2518 genotype did not affect the treatment outcome in patients with chronic periodontitis. CONCLUSION: MCP-1 -2518 A/G genotype might be useful in predicting less favorable nonsurgical treatment outcome in patients with aggressive periodontitis. However, MCP-1 -2518 gene polymorphism may not play a role in patients with chronic periodontitis. This study suggests that MCP-1 -2518 genotype may influence the outcome of nonsurgical periodontal treatment in aggressive periodontitis patients.

Dysfunction Screening in Experimental Arteriovenous Grafts for Hemodialysis Using Fractional-Order Extractor and Color Relation Analysis.

In physical examinations, hemodialysis access stenosis leading to dysfunction occurs at the venous anastomosis site or the outflow vein. Information from the inflow stenosis, such as blood pressure, pressure drop, and flow resistance increases, allows dysfunction screening from the stage of early clots and thrombosis to the progression of outflow stenosis. Therefore, this study proposes dysfunction screening model in experimental arteriovenous grafts (AVGs) using the fractional-order extractor (FOE) and the color relation analysis (CRA). A Sprott system was designed using an FOE to quantify the differences in transverse vibration pressures between the inflow and outflow sites of an AVG. Experimental analysis revealed that the degree of stenosis (DOS) correlated with an increase in fractional-order dynamic errors (FODEs). Exponential regression was used to fit a non-linear curve and can be used to quantify the relationship between the FODEs and DOS (R (2) = 0.8064). The specific ranges were used to evaluate the stenosis degree, such as DOS: <50, 50-80, and >80%. A CRA-based screening method was derived from the hue angle-saturation-value color model, which describes perceptual color relationships for the DOS. It has a flexibility inference manner with color visualization to represent the different stenosis degrees, which has average accuracy >90% superior to the traditional methods. This in vitro experimental study demonstrated that the proposed model can be used for dysfunction screening in stenotic AVGs.

[Reducing expenditure on infectious waste handling in the hemodialysis room].

Developing awareness of environmental protection issues and rising costs of medical treatment are causing all medical treatment centers to reduce expenditure on the processing of infectious hazardous wastes. This has become a major matter of policy in most hospitals. This project was undertaken because, in one unit, expenditure on infectious hazardous waste processing began to cost 50% of the hospital's entire monthly spending on such processing. A specialist team was established, which put into practice a monitoring plan and improvement measures. The results were as follows. First, with guidance, staff members realized the importance of reducing the quantity of infectious hazardous wastes. Second, infectious hazardous wastes were reduced by reducing the quantity, recycling, and not being wasteful. Third, following this effort, the hemodialysis room in question was able to save NT 2,786 dollars per month in expenditure on hygienic materials and waste handling fees of NT 5,597 dollars per month. A total of NT 100,596 dollars was saved for the whole year. Fourth, the whole improvement project target completion rate was 240% and the progress rate was 13.3%.
