RESUMO
BACKGROUND: Hemodialysis holds the highest incidence and prevalence rate in Taiwan globally. However, the implementation of advance care planning (ACP), advance directives (AD), and patient self-determination acts (PSDA) remains limited. Our objective was to examine the current status of ACP, AD and PSDA and potential opportunities for enhancement. METHODS: We developed a novel questionnaire to assess individuals' knowledge, attitudes, and intentions regarding ACP, AD, and PSDA. We also collected baseline characteristics and additional inquiries for correlation analysis to identify potential factors. Student's t-test and Analysis of Variance were employed to assess significance. RESULTS: Initially, a cohort of 241 patients was initially considered for inclusion in this study. Subsequently, 135 patients agreed to participate in the questionnaire study, resulting in 129 valid questionnaires. Among these respondents, 76 were male (59.9%), and 53 were female (41.1%). Only 13.2% had signed AD. A significant portion (85.3%) indicated that they had not discussed their dialysis prognosis with healthcare providers. Additionally, a mere 14% engaged in conversations about life-threatening decisions. Ninety percent believed that healthcare providers had not furnished information about ACP, and only 30% had discussed such choices with their families. The findings revealed that the average standardized score for ACP and AD goals was 84.97, while the attitude towards PSDA received a standardized score of 69.94. The intention score stood at 69.52 in standardized terms. Potential candidates for ACP initiation included individuals aged 50 to 64, possessing at least a college education, being unmarried, and having no history of diabetes. CONCLUSION: Patients undergoing hemodialysis exhibited a significant knowledge gap concerning ACP, AD, and the PSDA. Notably, a substantial number of dialytic patients had not received adequate information on these subjects. Nevertheless, they displayed a positive attitude, and a considerable proportion expressed a willingness to sign AD. It is imperative for nephrologists to take an active role in initiating ACP discussions with patients from the very beginning.

The distribution and functions of neurons in scleractinian corals remain largely unknown. This study focused on the Arg-Phe amide family of neuropeptides (RFamides), which have been shown to be involved in a variety of biological processes in animals, and performed molecular identification and characterization in the adult scleractinian coral Euphyllia ancora. The deduced amino acid sequence of the identified RFamide preprohormone was predicted to contain 20 potential neuropeptides, including 1 Pro-Gly-Arg-Phe (PGRF) amide and 15 Gln-Gly-Arg-Phe (QGRF) amide peptides. Tissue distribution analysis showed that the level of transcripts in the tentacles was significantly higher than that in other polyp tissues. Immunohistochemical analysis with the FMRFamide antibody showed that RFamide neurons were mainly distributed in the epidermis of the tentacles and mouth with pharynx. Treatment of E. ancora polyps with synthetic QGRFamide peptides induced polyp contraction. The induction of polyp contraction by QGRFamide peptide treatment was also observed in another scleractinian coral, Stylophora pistillata. These results strongly suggested that RFamides play a role in the regulation of polyp contraction in adult scleractinians.

Introduction: Literature is limited on quantified acute stress reaction, the impact of event scale on medical staff when facing medical malpractice (MMP), and how to individually care for staff. Methods: We analyzed data in the Taichung Veterans General Hospital from October 2015 to December 2017, using the Stanford Acute Stress Reaction Questionnaire (SASRQ), the Impact of Event Scale-Revised (IES-R), and the medical malpractice stress syndrome (MMSS). Results and Discussion: Of all 98 participants, most (78.8%) were women. Most MMPs (74.5%) did not involve injury to patients, and most staff (85.7%) indicated receiving help from the hospital. The internal-consistency evaluations of the three questionnaires showed good validity and reliability. The highest score of IES-R was the construct of intrusion (30.1); the most severe construct of SASRQ was "Marked symptoms of anxiety or increased arousal," and the most were having mental and mild physical symptoms for MMES. A higher total IES-R was associated with younger age (<40 y/o), and more severe injury on patients (mortality). Those who indicated receiving very much help from the hospital were those having significantly lower SASRQ sores. Our study highlighted that hospital authorities should regularly follow up on staff's response to MMP. With timely interventions, vicious cycles of bad feelings can be avoided, especially in young, non-doctor, and non-administrative staff.

The receptor guanylate cyclases (rGCs) in animals serve as sensitive chemoreceptors to detect both chemical and environmental cues. In reproduction, rGCs were shown to be expressed on sperm and serve as receptors for egg-derived sperm-activating and sperm-attracting factors in some echinoderms and mammals. However, sperm-associated rGCs have only been identified in some deuterostomes thus far, and it remains unclear how widely rGCs are utilized in metazoan reproduction. To address this issue, this study investigated the existence and expression of rGCs, particularly asking if rGCs are involved in the reproduction of a basal metazoan, phylum Cnidaria, using the stony coral Euphyllia ancora. Six paralogous rGCs were identified from a transcriptome database of E. ancora, and one of the rGCs, GC-A, was shown to be specifically expressed in the testis. Immunohistochemical analyses demonstrated that E. ancora GC-A protein was expressed in the spermatocytes and spermatids and eventually congregated on the sperm flagella during spermatogenesis. These findings suggest that GC-A may be involved in the regulation of sperm activity and/or functions (e.g., fertilization) in corals. This study is the first to perform molecular characterization of rGCs in cnidarians and provides evidence for the possible involvement of rGCs in the reproduction of basal metazoans.
