Humanity behind the intention of primary caregiver to choose withdrawing life-sustaining treatment for terminating patients.

OBJECTIVE: Mechanical ventilation, a measure of life-sustaining treatment (LST), may not be helpful and can be devastating for patients with terminal illness. We explored the effects of demographic characteristics, attitude, subjective norms, and perceived behavioral control on the behavioral intentions of primary caregivers to withdraw LST of long-term ventilator-dependent patients. METHODS: Primary caregivers of ventilator-dependent patients in the respiratory care units of six hospitals participated in the study. A cross-sectional design including the domains of attitude, subjective norms, perceived behavioral control, and behavioral intention was adopted. RESULTS: Valid data for 99 participants were analyzed using logistic regression. Religious belief, a spousal relationship with the patient, item 5 in subjective norms, and item 5 in perceived behavioral control positively influenced the intention to withdraw patient LST. CONCLUSIONS: Religious beliefs, a spousal relationship, perceived behavioral control (confidence in relieving patient suffering), and the opportunity of current favorable subjective norms are major determinants of the intention to withdraw patients' LST. PRACTICE IMPLICATIONS: Shared decision-making with the kin and primary caregivers of long-term ventilator-dependent patients at the end of life is crucial.

Elevated galanin receptor type 2 primarily contributes to mechanical hypersensitivity after median nerve injury.

In this study, we investigated temporal changes in galanin receptor type 2 (GalR2) expression in NF200-, galanin-, neuropeptide Y (NPY)-, and neuronal nitric oxide synthase (nNOS)-like immunoreactive (LI) dorsal root ganglion (DRG) neurons after median nerve chronic constriction injury (CCI), and the effects of GalR2 on c-Fos expression in the cuneate nucleus (CN). Double immunofluorescence labeling methods were used to appraise changes in GalR2 expression in NF200-LI, galanin-LI, NPY-LI, and nNOS-LI DRG neurons after CCI. The von Frey assay was used to assess the efficiency of intraplantar administration of saline, M871 (a GalR2 antagonist), or AR-M1896 (a GalR2 agonist) on neuropathic signs of rats with CCI. The effects of alterations in c-Fos expression were assessed in all treatments. The percentage of GalR2-LI neurons in lesioned DRGs increased and peaked at 1 week after CCI. We further detected that percentages of GalR2-LI neurons labeled for NF200, galanin, NPY, and nNOS significantly increased following CCI. Furthermore, M871 remarkably attenuated tactile allodynia, but the sensation was slightly aggravated by AR-M1896 after CCI. Consequentially, after electrical stimulation of the CCI-treated median nerve, the number of c-Fos-LI neurons in the cuneate nucleus (CN) was significantly reduced in the M871 group, whereas it increased in the AR-M1896 group. These results suggest that activation of GalR2, probably through NPY or nitric oxide, induces c-Fos expression in the CN and transmits mechanical allodynia sensations to the thalamus.

Factors affecting caregivers' perceptions of residents' oral health in long-term care facilities in Taiwan.

The purpose of this study was to investigate the differences between resident oral care policies provided by 2 types of long-term care (LTC) institutions. The study also investigated factors affecting LTC institutional caregivers' perceptions of the residents' oral health. Overall, 103 completed questionnaires were returned. Of these, 44 were from senior citizen welfare institutions, and 59 were from nursing homes. The variables affecting these perceptions included institution type and whether the residents attended hospital dental clinics or consulted a hospital doctor regarding oral health problems. The research results showed that institution type and whether an oral care-related professional was available in an institution were correlated with an increase in institutional caregivers' perceptions of oral care.
