Nurse-led intervention to improve oral mucosal health of intubated patients in the intensive care unit: A prospective study.

BACKGROUND: This prospective study aimed to explore the effectiveness of an oral care intervention with Tegaderm on the oral mucosal health of intubated patients. METHODS: A total of 70 intubated patients were included and randomly assigned to 1 of 3 groups, clean water brushing teeth (n = 23), brushing teeth combined with mouthwash (BTM) (n = 23), and brushing teeth combined with mouthwash and Tegaderm (BTMT) (n = 24). The Oral Mucositis Assessment Scale (OMAS) was applied to evaluate the patient's oral mucosal health before and after oral care intervention. RESULTS: The BTMT group had lower OMAS scores in almost all regions of the oral cavity, compared to the brushing teeth and BTM groups. The general linear model for repeated measurement indicated the BTMT group had the lowest total OMAS scores from Day 2 to Day 4 after the initiation of baseline OMAS evaluation. Of the 3 intervention groups, the BTMT group had the shortest length of endotracheal intubation. The BTMT group had the lowest incidence rate of ventilator-associated pneumonia; however, no significant between-group differences were found. CONCLUSIONS: BTMT effectively reduced the decline in oral mucosal health that was caused by endotracheal intubation and shortened the length of endotracheal intubation.

Identifying KCNJ5 Mutation in Aldosterone-Producing Adenoma Patients With Baseline Characteristics Using Machine Learning Technology.

Background: Primary aldosteronism is characterized by inappropriate aldosterone production, and unilateral aldosterone-producing adenoma (uPA) is a common type of PA. KCNJ5 mutation is a protective factor in uPA; however, there is no preoperative approach to detect KCNJ5 mutation in patients with uPA. Objectives: This study aimed to provide a personalized surgical recommendation that enables more confidence in advising patients to pursue surgical treatment. Methods: We enrolled 328 patients with uPA harboring KCNJ5 mutations (n = 158) or not (n = 170) who had undergone adrenalectomy. Eighty-seven features were collected, including demographics, various blood and urine test results, and clinical comorbidities. We designed 2 versions of the prediction model: one for institutes with complete blood tests (full version), and the other for institutes that may not be equipped with comprehensive testing facilities (condensed version). Results: The results show that in the full version, the Light Gradient Boosting Machine outperformed other classifiers, achieving area under the curve and accuracy values of 0.905 and 0.864, respectively. The Light Gradient Boosting Machine also showed excellent performance in the condensed version, achieving area under the curve and accuracy values of 0.867 and 0.803, respectively. Conclusions: We simplified the preoperative diagnosis of KCNJ5 mutations successfully using machine learning. The proposed lightweight tool that requires only baseline characteristics and blood/urine test results can be widely applied and can aid personalized prediction during preoperative counseling for patients with uPA.

Experiences of oncology healthcare personnel in international medical service quality: a phenomenological study.

BACKGROUND: With the globalization of medical services on the rise, Asia has ascended to a destination of choice for its high-quality medical services at very reasonable rates. Monitoring the quality of the international medical industry is vital to maintain service demand. The experiences of healthcare personnel (HCP) involved in international medical services (IMS) regarding the provision of services to international cancer patients have not yet been discussed. This study aimed to explore oncology HCP experiences of IMS quality in caring for international cancer patients in Taiwan. METHODS: Descriptive phenomenological method and were analyzed through Colaizzi's seven-step approach. In this study, 19 respondents were collected data by using in-depth semi-structured interviews. An average interview lasted approximately 45 min. RESULTS: Four major themes were identified from the interviews: patient selection, psycho-oncology care, predicaments, and promoting suggestions. Additionally, thirteen subthemes emerged, including necessary selection of patients, reasons for unwillingness to enroll international patients, helpless patients, emotional distress, care with warmth, insufficient manpower, an unfair reward mechanism, poor hardware equipment, the predicaments of oncology care, various publicity strategies, one-on-one service model, design of a designated area, and reasonable benefit distribution. CONCLUSIONS: This study explored oncology HCP experiences of IMS quality in caring for international cancer patients, with implications for hospitals in developing high-quality IMS. Due to the fact that IMS is a global trend, HCPs, administrators, and policy-makers are advised to improve the quality of IMS in the oncology department, which has been the least studied field in IMS quality.

Risk of cognitive impairment in men with advanced prostate cancer treated with NHAs: A systematic review and network meta-analysis.

Novel hormonal agents (NHAs) have significantly improved outcomes in men with advanced prostate cancer. However, it remains unclear whether NHAs are associated with subsequent cognitive impairment. Thus, we sought to perform a network meta-analysis to compare the risk of cognitive impairment across NHA types. Databases (PubMed, Embase, Scopus, and Web of Science), trial registries (Clinicaltrial.gov), the European Medicines Agency, and the US Food and Drug Administration drug safety reports were searched from inception through July 30, 2021. Eligible studies were clinical trials evaluating the risk of cognitive impairment between NHAs and placebo/standard care. Two independent investigators extracted the data and performed quality assessments using the Cochrane Risk of Bias Tool and ROBINS-I. We estimated the risk ratios by the frequentist approach and calculated the ranking probabilities of all treatments with the surface under the cumulative ranking probabilities. The primary outcome and secondary outcome were odds ratio (OR) and incidence rate ratio of cognitive impairment, respectively. We identified 15 trials with 14,723 participants comparing HNAs with placebo/standard care. Treatments associated with cognitive impairment, from the most to the least, were enzalutamide (OR, 3.66; 95% confidence interval [CI], 2.84-4.73), apalutamide (OR, 1.76; 95% CI, 1.08-2.87), abiraterone acetate (OR, 1.64; 95% CI, 1.01-2.45), and darolutamide (OR, 1.11 95% CI, 0.51-2.39). After adjustment of treatment time duration, enzalutamide still had the highest risk of cognitive impairment with an incidence rate ratio of 2.17 (95% CI, 1.65-2.78). These findings suggest that NHAs, especially enzalutamide, may increase the risk of cognitive impairment compared with placebo/standard care.

GRK3 as a Prognosis Biomarker in Gastric Cancer.

Background: Globally, gastric cancer is ranked 4th and 3rd in terms of incidence and mortality rate among all cancer types. This study aimed to examine the relationship between G protein-coupled receptor kinase 3 (GRK3) and gastric cancer prognosis and investigate the role of GRK3 in gastric cancer carcinogenesis. Methods: GRK3 level in gastric tissues and cells were determined using immunohistochemistry and immunoblotting. Kaplan-Meier analysis with the log-rank test was employed to evaluate the relationship between GRK3 expression and gastric cancer prognosis. RNAi technology was applied to examine the effects of GRK3 inhibition on gastric cancer proliferation and spread. Results: GRK3 overexpression was correlated significantly with lymphatic metastasis (P = 0.0011), distant metastasis (P < 0.0001), TNM stage (P = 0.0035), and vascular invasion (P = 0.0025). Kaplan-Meier survival analysis showed that the disease-free survival and overall survival of patients with high GRK3 expression were significantly shorter than those of patients with low GRK3 expression. Multivariate Cox regression analysis also showed that the overexpression of GRK3 was an independent prognostic biomarker of gastric cancer (P = 0.029). In cultured gastric cancer cells, GRK3 knockdown inhibited cell proliferation, migration, and invasion. Further analysis revealed that more GRK3-knockdown cells were in G0/G1 phase and few cells were in S phase, thereby inhibiting cell proliferation. Conclusions: GRK3 overexpression can be a candidate biomarker for gastric cancer prognosis. GRK3 is also a potential therapeutic target for gastric cancer.

Using a Hybrid Radioenhancer to Discover Tumor Cell-targeted Treatment for Osteosarcoma: An In Vitro Study.

Osteosarcoma is insensitive to radiation. High-dose radiation is often used as a treatment but causes side effects in patients. Hence, it is important to develop tumor cell-- targeted radiotherapy that could improve radiotherapy efficiency on tumor cells and reduce the toxic effect on normal cells during radiation treatment. In this study, we developed an innovative method for treating osteosarcoma by using a novel radiation-enhancer (i.e., carboxymethyl-hexanoyl chitosan-coated self-assembled Au@Fe3O4 nanoparticles; CSAF NPs). CSAF NPs were employed together with 5-aminolevulinic acid (5- ALA) to achieve tumor cell-targeted radiotherapy. In this study, osteosarcoma cells (MG63) and normal cells (MC3T3-E1) were used for an in vitro investigation, in which reactive oxygen species (ROS) assay, cell viability assay, clonogenic assay, and western blot were used to confirm the treatment efficiency. The ROS assay showed that the combination of CSAF NPs and 5-ALA enhanced radiation-induced ROS production in tumor cells (MG63); however, this was not observed in normal cells (MC3T3-E1). The cell viability ratio of normal cells to tumor cells after treatment with CSAF NPs and 5-ALA reached 2.79. Moreover, the clonogenic assay showed that the radiosensitivity of MG63 cells was increased by the combination use of CSAF NPs and 5-ALA. This was supported by performing a western blot that confirmed the expression of cytochrome c (a marker of cell mitochondria damage) and caspase-3 (a marker of cell apoptosis). The results provide an essential basis for developing tumor-cell targeted radiotherapy by means of low-- dose radiation.

An Interpretative Study on Nurses' Perspectives of Working in an Overcrowded Emergency Department in Taiwan.

PURPOSE: This study aims to gain in-depth understanding of nurses' perspectives of working in an overcrowded emergency. METHODS: Symbolic interactionism and Charmaz's construction of grounded theory were used. Purposive sampling at the start of the study and a further theoretical sampling by snowball technique were used to recruit 40 registered nurses (RN) to participate in in-depth, semi-structured interviews between May and November, 2014. Data analysis included analytic techniques of initial, focused and theoretical coding. RESULTS: Study findings showed searching for work role is derived by the themes of Finding the role of positioning in Emergency Department (ED), Recognizing causes of ED overcrowding, and Confined working environment. Nurses' work experience which represents the RNs not gained control over their work, as care actions influenced by the problematic overcrowded circumstance of the ED environment. CONCLUSION: The findings fill a gap in knowledge about how RNs experience their work role in the context of an overcrowded Emergency Department in Taiwan. Arising from the study result include taking account of nurses' perspectives when planning staff/patient ratios, strategies to reduce waiting time and ensure that clients receive appropriate care.

Presurgical Concerns of Primary Family Caregivers of Children With Cerebral Palsy.

BACKGROUND: Primary family caregivers (PFCs) of children with cerebral palsy have many worries and concerns when their children face orthopedic surgery. Levels of PFC stress about the upcoming surgery is related to the child's level of gross motor function as well as the support they receive from medical professionals. PURPOSE: The purposes of the present study were to (1) explore the levels of concern about orthopedic surgery; and (2) explore the predictive factors associated with concerns about orthopedic surgery among PFCs of children with cerebral palsy during the preoperative period. METHODS: A cross-sectional, correlational study was conducted. Primary family caregivers were assessed preoperatively using the Single-event Multilevel Surgery Scale, Social Support Scale, Gross Motor Function Classification System-Expanded and Revised, and background information form. Primary family caregivers were recruited from the outpatient department of orthopedic surgery and pediatric rehabilitation of a medical center in northern Taiwan. Data were analyzed by descriptive analysis, Pearson product-moment correlation, and multiple regression analysis. RESULTS: A total of 63 eligible subjects were enrolled in this study. Primary family caregivers had moderate levels of concern and mild-to-moderate levels of social support. The higher severity of motor function impairment in children with cerebral palsy, prior caregiving by PFCs for another family member, and PFCs' lower level of social support from healthcare providers were associated with higher levels of PFC concern. CONCLUSIONS: Concerns about orthopedic surgery is an overlooked issue that needs more attention from healthcare providers. This study determined that PFCs who perceived a lack of social support from their healthcare providers and those with children who had limited gross motor function were more concerned and anxious about their children's upcoming orthopedic surgery. Health professionals should provide adequate health education and counseling to help PFCs of children with cerebral palsy in the decision-making process prior to orthopedic surgery.

Workplace interpersonal conflicts among the healthcare workers: Retrospective exploration from the institutional incident reporting system of a university-affiliated medical center.

OBJECTIVE: There have been concerns about the workplace interpersonal conflict (WIC) among healthcare workers. As healthcare organizations have applied the incident reporting system (IRS) widely for safety-related incidents, we proposed that this system might provide a channel to explore the WICs. METHODS: We retrospectively reviewed the reports to the IRS from July 2010 to June 2013 in a medical center. We identified the WICs and typed these conflicts according to the two foci (task content/process and interpersonal relationship) and the three properties (disagreement, interference, and negative emotion), and analyzed relevant data. RESULTS: Of the 147 incidents with WIC, the most common related processes were patient transfer (20%), laboratory tests (17%), surgery (16%) and medical imaging (16%). All of the 147 incidents with WIC focused on task content or task process, but 41 (27.9%) also focused on the interpersonal relationship. We found disagreement, interference, and negative emotion in 91.2%, 88.4%, and 55.8% of the cases, respectively. Nurses (57%) were most often the reporting workers, while the most common encounter was the nurse-doctor interaction (33%), and the majority (67%) of the conflicts were experienced concurrently with the incidents. There was a significant difference in the distribution of worker job types between cases focused on the interpersonal relationship and those without (p = 0.0064). The doctors were more frequently as the reporter when the conflicts focused on the interpersonal relationship (34.1%) than not on it (17.0%). The distributions of worker job types were similar between those with and without negative emotion (p = 0.125). CONCLUSIONS: The institutional IRS is a useful place to report the workplace interpersonal conflicts actively. The healthcare systems need to improve the channels to communicate, manage and resolve these conflicts.

Integrating team resource management program into staff training improves staff's perception and patient safety in organ procurement and transplantation: the experience in a university-affiliated medical center in Taiwan.

BACKGROUND: The process involved in organ procurement and transplantation is very complex that requires multidisciplinary coordination and teamwork. To prevent error during the processes, teamwork education and training might play an important role. We wished to evaluate the efficacy of implementing a Team Resource Management (TRM) program on patient safety and the behaviors of the team members involving in the process. METHODS: We implemented a TRM training program for the organ procurement and transplantation team members of the National Taiwan University Hospital (NTUH), a teaching medical center in Taiwan. This 15-month intervention included TRM education and training courses for the healthcare workers, focused group skill training for the procurement and transplantation team members, video demonstration and training, and case reviews with feedbacks. Teamwork culture was evaluated and all procurement and transplantation cases were reviewed to evaluate the application of TRM skills during the actual processes. RESULTS: During the intervention period, a total of 34 staff members participated the program, and 67 cases of transplantations were performed. Teamwork framework concept was the most prominent dimension that showed improvement from the participants for training. The team members showed a variety of teamwork behaviors during the process of procurement and transplantation during the intervention period. Of note, there were two potential donors with a positive HIV result, for which the procurement processed was timely and successfully terminated by the team. None of the recipients was transplanted with an infected organ. No error in communication or patient identification was noted during review of the case records. CONCLUSION: Implementation of a Team Resource Management program improves the teamwork culture as well as patient safety in organ procurement and transplantation.
