Effects of the frequency of ostomy management reinforcement education on self-care knowledge,self-efficacy,and ability of stoma appliance change among Korean hospitalised ostomates

Patients who undergo stoma surgery experience difficulties in adapting physically and psychologically. The priority is to support them in learning self-care for successful rehabilitation and psychosocial adaption to a new life. In order to do this, it is important to provide ostomates with repetitive reinforcement education on self-care in a continuous and individual manner, not just to increase knowledge or perform related skills. This study aims to evaluate the effects of ostomy management reinforcement education (OMRE) in ostomates and to identify the optimal frequency of reinforcement education using an equivalent control group post-test design. Participants were 60 ostomates admitted to a university hospital after ostomy formation surgery, and they were randomly assigned to a control and two experimental groups of this study. The OMRE was given to the control group (n = 20), experimental group 1 (n = 20), and experimental group 2 (n = 20) once, twice, and three times, respectively. Participants' self-care knowledge, self-efficacy, and ability of stoma appliance change were evaluated before and after the OMRE. Major results of this study were as follows: the self-care knowledge score of post-test was higher than the pretest in the control, experimental 1, and experimental two groups (P < 0.001). The self-efficacy score of post-test was higher than the pretest in the control, experimental 1, and experimental 2 groups (P < 0.001). The self-care knowledge score according to the frequency of OMRE did not differ among the control, experimental 1, and experimental 2 groups (F = 1.921, P = 0.156). The self-efficacy score according to the frequency of OMRE was significantly different between the control and experimental groups (F = 8.616, P = 0.001), but there was no difference between the experimental 1 and experimental 2 groups (Scheffe's post-hoc analysis: a < b, c). The ability of stoma appliance change score according to the frequency of OMRE was significantly different between the control and experimental groups (F = 49.546, P < 0.001), but there was no difference between the experimental 1 and experimental 2 groups (Scheffe's post-hoc analysis: a < b, c). Results of this study suggested that the OMRE was effective for promoting hospitalised ostomates' self-care knowledge, self-efficacy, and ability of stoma appliance change, and two sessions of the OMRE was the most effective. Findings of this study may be useful in planning education programmes designed to improve self-care ability for hospitalised ostomates.

结论 性别、年龄、工龄、接触职业病危害因素均可能影响五官科异常检出率，应采取积极的针对性预防措施。
     

The effect of oral appliances that advanced the mandible forward and limited mouth opening in patients with obstructive sleep apnea: A systematic review and meta‐analysis of randomised controlled trials

Oral appliances (OAs) have demonstrated efficacy in treating obstructive sleep apnea (OSA), but many different OA devices are available. The Japanese Academy of Dental Sleep Medicine supported the use of OAs that advanced the mandible forward and limited mouth opening and suggested an evaluation of their effects in comparison with untreated or CPAP. A systematic search was undertaken in 16 April 2012. The outcome measures of interest were as follows: Apnea Hypopnea Index (AHI), lowest SpO₂, arousal index, Epworth Sleepiness Scale (ESS), the SF‐36 Health Survey. We performed this meta‐analysis using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Five studies remained eligible after applying the exclusion criteria. Comparing OA and control appliance, OA significantly reduced the weighted mean difference (WMD) in both AHI and the arousal index (favouring OA, AHI: ?7·05 events h^?1; 95% CI, ?12·07 to ?2·03; P = 0·006, arousal index: ?6·95 events h^?1; 95% CI, ?11·75 to ?2·15; P = 0·005). OAs were significantly less effective at reducing the WMD in AHI and improving lowest SpO₂ and SF‐36 than CPAP, (favouring OA, AHI: 6·11 events h^?1; 95% CI, 3·24 to 8·98; P = 0·0001, lowest SpO₂: ?2·52%; 95% CI, ?4·81 to ?0·23; P = 0·03, SF‐36: ?1·80; 95% CI, ?3·17 to ?042; P = 0·01). Apnea Hypopnea Index and arousal index were significantly improved by OA relative to the untreated disease. Apnea Hypopnea Index, lowest SpO₂ and SF‐36 were significantly better with CPAP than with OA. The results of this study suggested that OAs improve OSA compared with untreated. CPAP appears to be more effective in improving OSA than OAs.     

Molar Distalization with Different Pendulum Appliances: In Vitro Registration of Orthodontic Forces and Moments in the Initial Phase

Abstract. Aim: Registration of the orthodontic forces and moments acting with different types of pendulum appliance for non-compliance upper molar distalization in an in vitro study. Material and Methods: The purpose-designed test set-up comprised the following components: artificial maxilla with anchorage unit and two electrothermodynamic (ETD) molars, electronic measuring unit for temperature control and regulation, and a sensor unit with force-moment sensor, analog/digital converter and data readout unit. This set-up permitted virtually authentic simulation of in vivo conditions on the one hand and precise determination of the force systems on the other.The appliances investigated were the standard pendulum appliance with U-loop activation according to Hilgers and with uprighting activation according to Byloff, the M-pendulum with U-loop activation according to Scuzzo, and the Pendulum K with initial uprighting activation, toe-in bend and incorporated distal screw according to Kinzinger. Results and Conclusions: The effects shown by the standard pendulum appliance and the M-pendulum over a 3 mm simulated distalization increment were a marked decrease in the distally directed forces, and an increase in the intrusive and palatally directed forces as well as in the distoinclinatory, mesially inward, and palatally rotating moments.Activations in the U-loop region of the pendulum springs induced an increase in distally and buccally directed forces and in uprighting and buccally rotating moments as well as a marked rise in extrusive forces. Whereas the activation described by Hilgers led to mesially outward rotating moments, activation according to Scuzzo resulted in a further increase in the mesially inward rotating moments.In the measured standard pendulum appliances, uprighting activation at the end of the pendulum according to Byloff led to an increase in distally and buccally directed as well as in mildly intrusive forces, and to an increase in uprighting as well as in buccally and mesially outward rotating moments.With the Pendulum K according to Kinzinger, the initial toe-in bend and uprighting activation in the region of the end of the pendulum spring together with regular adjustment of the incorporated distal screw permitted virtually translatory molar distalization: constantly distalizing forces with slight intrusive, buccally directed, and rotating side effects.
