Validity and Reliability of a Short Form of the Questionnaire for the Reflective Practice of Nursing Involving Invasive Mechanical Ventilation: A Cross-Sectional Study.

The number of patients on ventilators is rapidly increasing owing to the coronavirus pandemic. The previously developed Questionnaire for the Reflective Practice of Nursing Involving Invasive Mechanical Ventilation (Q-RPN-IMV) for the care of patients on ventilators includes nurses' thought processes as items. This study aims to develop a short form of the Q-RPN-IMV for immediate use in practice and to test its reliability and validity. A convenience sample of 629 participants was used to explore the factor structure using factor analysis. The test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The study was a cross-sectional design instrument development study and was reported according to GRRAS guidelines. Q-RPN-IMV short form was divided into ventilator management and patient management. The ventilator management comprised 31 items organized into six factors. Cronbach's alpha ranged from 0.82 to 0.91, and the ICC ranged from 0.82 to 0.89. The patient management comprised 27 items organized into five factors. Cronbach's alpha ranged from 0.75 to 0.97, and ICC ranged from 0.75 to 0.97. The Q-RPN-IMV short form is a reliable and validated instrument for assessing care for patients on ventilators. This study was not registered.

Effects of a virtual reality intervention on dementia care education among acute care nurses in Japan: A non-randomised controlled trial.

This study aimed to evaluate the effects of a virtual reality intervention for dementia care education in Japanese acute care nurses. Non-randomised controlled trial was used to assess the effectiveness of the intervention pre- and post-intervention and at a 1-month follow-up. This study enrolled 20 and 19 nurses in the intervention and control groups, respectively. Generalized estimating equation analyses revealed significant differences in scores on the Dementia Nursing Competency Scale in Acute Hospitals and Staff Experiences of Working with Dementia Residents questionnaire in the intervention group. A post hoc test revealed significantly higher scores on the Dementia Nursing Competency Scale in Acute Hospitals at 1 month after compared with pre-intervention. Staff Experiences of Working with Dementia Residents questionnaire scores were significantly lower at pre- than that at post-intervention and 1 month after intervention. These findings could improve competency of dementia nursing care and attitudes toward people with dementia.

Dementia nursing competency in acute care settings: A concept analysis.

AIM: To critically analyse the concept of dementia nursing competency in acute care settings. BACKGROUNDS: The nursing care needs of patients with dementia are increasing in acute care settings. However, a framework for the dementia nursing competency has not been explicitly outlined. DESIGN: Rodgers' evolutionary method for concept analysis. DATA SOURCES: Competenc* AND dementia AND nurs* AND acute OR hospital OR clinical were selected from the MEDLINE, CINAHL, PsycINFO, CiNii, and Google Scholar for publication from 2006 to 2017. REVIEW METHODS: All 29 articles were identified. Data were analysed with a particular focus on the attributes, antecedents, and consequences of the concept. RESULTS: Six attributes were identified: respecting patient individuality, applying ethical considerations, providing person-centred care, possessing responsibility, coordinating external environments, and possessing care coordination and facilitation skills. Identified antecedents included building theoretical and clinical knowledge, developing an awareness of dementia and its risk behaviours, performing assessments of dementia nursing practice, developing relationships with patients with dementia, and applying a team approach. Applying the competency led to positive consequences for patients, nurses, and patient-nurse and nursing team relationships. CONCLUSION: Developing the dementia nursing competency results in stronger emotional interventions and adds a human-to-human connection.

Development of a Questionnaire for the Reflective Practice of Nursing Involving Invasive Mechanical Ventilation: Assessment of validity and reliability.

AIM: To develop the Questionnaire for Reflective Practice of Nursing Involving Invasive Mechanical Ventilation (Q-RPN-IMV), a Japanese self-evaluation instrument for ward nurses' IMV practices. DESIGN: Cross-sectional survey. METHODS: Participants were 305 ward nurses from five hospitals in Japan with nursing involving invasive mechanical ventilation. Items concerning the process of nursing practice, including the thought process related to ventilator care, were collected from the literature and observation and interviews with five IMV specialists. Construct validity, concurrent validity, internal consistency and test-retest reliability were tested. RESULTS: Initially, 141 items were collected and classified into three domains (i.e., observation, assessment and practice). Examination of exploratory factor analysis yielded five factors in the observation domain, six factors in the assessment domain and six factors in the practice domain. The data exhibited internal consistency, stability and concurrent validity. Items of practical content, including thoughts on ventilator care, are useful for preparing educational programmes.

A membrane protein, TMCO5A, has a close relationship with manchette microtubules in rat spermatids during spermiogenesis.

We isolated the transmembrane and coiled-coil domains 5A (Tmco5A) gene using polymerase chain reaction-based subtraction technique and showed that Tmco5A was predominantly expressed in rat testes starting at 4 weeks of postnatal development. When expressed in COS7 cells, TMCO5A was found to be distributed in the endoplasmic reticulum-nuclear membrane (ER-NM) of cells as a membrane-associated protein, while TMCO5AΔC lacking the transmembrane region (TM) mislocalized and diffused throughout the cytoplasm. The result suggested that TM is responsible for the retention of TMCO5A at the ER-NM. Immunocytochemical and immunoblotting analyses indicated that TMCO5A was localized along the posterior part of the nuclei in both round and elongated rat spermatids but disappeared from epididymal spermatozoa. Double immunolabeling of isolated spermatids with the anti-TMCO5A and the anti-ß tubulin antibodies showed that TMCO5A was always found to be closely associated with developing manchette microtubules but did not completely colocalize with them. On the other hand, we found that almost all TMCO5A colocalized with SUN4, a linker of nucleoskeleton and cytoskeleton complex protein present at the posterior part of spermatid nuclei. These data suggested that TMCO5A is located closer to the nuclei than the manchette microtubules. It is likely that TMCO5A, in association with manchette microtubules, is involved in the process of spermiogenesis.

Volatiles emitted from the leaves of Laurus nobilis L. improve vigilance performance in visual discrimination task.

The leaves of Laurus noblis L. (laurel) are mainly used as a spice in cooking, and the essential oil obtained by steam distillation of the leaves is used as an additive in foods, drugs and cosmetics. We investigated the effect of the volatiles emitted from the leaves of L. noblis at different doses (low-dose and high-dose groups) on vigilance performance in a visual discrimination task. By inhaling volatiles of the leaves of L. noblis, the decrease of the rate of true hits found in the control group was prevented in the low-dose group. The high-dose group showed higher scores than the low-dose group for subjective effects related to negative emotion. Meanwhile, both groups showed physiological effects suggesting stimulation of circulation. These findings suggest that the volatiles emitted from the leaves of L. noblis at low concentration could be utilized to maintain a high level of vigilance performance, such as the rate of true hits by improving physiological arousal without incurring the detrimental performance effects of negative emotion.

Pulsed NMR study of network formation in the course of bulk polymerization of methyl acrylate.

The proton spin-spin relaxation time (T2) during the bulk polymerization of methyl acrylate was measured as a function of the reaction time at various temperatures. Three kinds of T2 (T2L (long), T2S (short) and T2M (intermediate)) were obtained as the polymerization proceeded. The fraction of T2S (FS) increased sigmoidally at a certain reaction time, while that of T2L (FL) decreased reciprocally. The former corresponded to the amount of a polymer whose molecular weight was sufficiently high enough to cause a tight entanglement that produced a transient network structure; the latter reflected a decrease in the mixture of the monomer and the low molecular weight of the polymer. T2M is considered to arise from a relatively mobile region of the entanglement. The relationship between the fractions of T2S + T2M and the polymer yield was found to be linear, which led us to monitor the polymer yield in real time during the polymerization in a non-distractive manner. 13C DD (dipolar decoupling)/MAS (magic angle spinning) NMR spectra were also measured to monitor the polymerization process in terms of the molecular motions between the main chain and the side chain in the formation of a network structure. The 13C DD/MAS NMR spectra show that the side chain motion became restricted as well as the main chain when the "Trommosdorff effect" (gel effect) was observed, and a part of the monomers were trapped in the network structure.
