Objective: The purpose of this study was to clarify the collaborative activities and mutual recognition between community comprehensive care unit nurses (Ns) and care managers (CM) in supporting the discharge of the elderly from the hospital. Methods: A total of 300 nurses working in community comprehensive care wards and 360 care managers working in B City in A Prefecture were surveyed using an anonymous self-administered questionnaire. Results: The highest percentage of responses regarding necessary collaborative activities with multiple professions in supporting hospital discharge were the same for Ns and CMs. The items regarding practice with the highest percentages were “relationship as a team” for Ns, and “user-centered awareness” for CM. While these professionals were willing to share information about their patients’ lives after discharge, the percentage of those explaining their expertise was low. It is thought that collaborative activities focusing on these aspects would lead to more appropriate discharge support.

BACKGROUND:Out-of-hospital cardiac arrest(OHCA) is a public health concern, and many studies have been conducted on return of spontaneous circulation(ROSC) and its prognostic *** thromboelastometry(ROTEM?), a point-of-care testing(POCT) method, has been useful for predicting ROSC in patients with OHCA, but very few studies have focused on patients with non-shockable rhythm. We examined whether the parameters of POCT could predict ROSC in patients with OHCA and accompanying non-shockable ***:This is a single-center, retrospective observational study. Complete blood count,blood gas, and ROTEM POCT measurements were used. This study included patients with nontraumatic OHCA aged 18 years or older who were transported to the emergency department and evaluated using POCT between January 2013 and December 2021. The patients were divided into the ROSC and non-ROSC groups. Prehospital information and POCT parameters were compared using receiver operating characteristic(ROC) curve analysis, and further logistic regression analysis was ***:Sixty-seven and 135 patients were in the ROSC and non-ROSC groups,respectively. The ROC curves showed a high area under the curve(AUC) for K^(+) of 0.77(95%confidence interval [CI]:0.71–0.83) and EXTEM amplitude 5 min after clotting time(A5) of 0.70(95%CI:0.62–0.77). The odds ratios for ROSC were as follows:female sex 3.67(95%CI:1.67–8.04);K^(+)0.64(95%CI:0.48–0.84);and EXTEM A5 1.03(95%CI:1.01–1.06).CONCLUSION:In OHCA patients with non-shockable rhythm, K^(+) level and the ROTEM parameter EXTEM A5 may be useful in predicting ROSC.

For the aim of synthesis of the carbon-iodine compound, the preparation of iodin e-included carbon using RF plasma CVD was studied. Iodine-included carbon was sy nthesized on Si substrate using ICP type RF plasma CVD apparatus. C2H5OH and I2 dissolved C2H5OH was used as reactant gases. As a result, surface morphologies o f Iodine included carbon films showed flat surfaces for each samples. On the str ucture of films estimated by Raman spectroscopy, amorphous carbon was recognized . And I2 peaks were observed in XPS spectra. As a result of friction test, frict ion coefficient of the sample growth with C2H5OH showed about 0.45. On the other hand, that of the sample with I2-C2H5OH showed about 0.3 and decrease of fricti on coefficient was recognized. Iodine inclusion for carbon materials can be achi eved by RF plasma CVD using an I2-C2H5OH reactant. The coefficient of iodine-inc luded carbon showed lower than of without iodine

The clinical evidence regarding the utility of magnifying endoscopy with narrow band imaging or endocytoscopy has also been evolving in regard to the diagnosis of IBD-associated neoplasia. These advanced endoscopic techniques are promising for multiple reasons;not only for making an accurate diagnosis of neoplasia, but also in determining if endoscopic resection is appropriate for such lesions in patients with IBD. In this review, we discuss the diagnostic accuracy and limitations of magnifying endoscopy in assessing IBD-associated neoplasia and examine the feasibility and outcomes of endoscopic resection for these lesions.

This investigation was made to estimate current normal concentrations of total mercury in the hair of Chinese coastal people. Hair samples were collected from 659 healthy inhabitants in the areas along the coast and the rivers (such as Shanghai, Ningbo, Dalian, Xiamen, and Zhoushan) of China from Feb. 2005 to June 2006. Total mercury concentrations in the samples were analyzed by the cold vapor atomic adsorption spectrometry method (CVAAS). The results showed the geometric mean concentration of total mercur...
