Multi-slice spiral computed tomography in differential diagnosis of gastric stromal tumors and benign gastric polyps, and gastric stromal tumor risk stratification assessment.

BACKGROUND: The biological characteristics of gastric stromal tumors are complex, and their incidence has increased in recent years. Gastric stromal tumors (GST) have potential malignant tendencies, and the probability of transformation into malignant tumors is as high as 20%-30%. AIM: To investigate the value of multi-slice spiral computed tomography (MSCT) in the differential diagnosis of GST and benign gastric polyps, and GST risk stratification assessment. METHODS: We included 64 patients with GST (GST group) and 60 with benign gastric polyps (control group), confirmed by pathological examination after surgery in PLA General Hospital, from January 2016 to June 2021. The differences in the MSCT imaging characteristic parameters and enhanced CT values between the two groups before surgery were compared. According to the National Institutes of Health's standard, GST is divided into low- and high-risk groups for MSCT imaging characteristic parameters and enhanced CT values. RESULTS: The incidences of extraluminal growth, blurred boundaries, and ulceration in the GST group were significantly higher than those in the control group (P < 0.05). The CT values and enhanced peak CT values in the arterial phase in the CST group were higher than those in the control group (P < 0.05). The MSCT differential diagnosis of GST and gastric polyp sensitivity, specificity, misdiagnosis rate, missed diagnosis rate, and areas under the curve (AUCs) were 73.44 %, 83.33%, 26.56%, 16.67%, 0.784, respectively. The receiver operating characteristic curves were plotted with the arterial CT value and enhanced peak CT value, with a statistical difference. The results showed that the sensitivity, specificity, misdiagnosis rate, missed diagnosis rate, and AUC value of arterial CT in the differential diagnosis of GST and gastric polyps were 80.18%, 62.20%, 19.82%, 37.80%, and 0.710, respectively. The sensitivity, specificity, misdiagnosis rate, missed diagnosis rate, and AUC value of the enhanced peak CT value in the differential diagnosis of GST and gastric polyps were 67.63%, 60.40%, 32.37%, 39.60%, and 0.710, respectively. The incidence of blurred lesion boundaries and ulceration in the high-risk group was significantly higher than that in the low-risk group (P < 0.05). The arterial phase and enhanced peak CT values in the high-risk group were significantly higher than those in the low-risk group (P < 0.05). CONCLUSION: Presurgical MSCT examination has important value in the differential diagnosis of GST and gastric benign polyps and can effectively evaluate the risk grade of GST patients.

An evaluation model for the development of more humane correctional institutions: Evidence from Penghu Prison.

Over time, correctional institutions have actively implemented innovations in prison administration. Most correctional institutions constitute conservative and closed societies. Generally, people do not have sufficient knowledge or understanding of penal correction. Therefore, it is difficult but necessary to break the stereotyped impression people hold about correctional institutions, actively integrate them into society, and encourage people to assume a more humane attitude towards correctional institutions. We conducted an inductive analysis of Penghu Prison administered by the Agency of Corrections, Ministry of Justice, Taiwan. After creating evaluation indices for the development of more humane correctional institutions, we conducted a survey to classify the evaluation indices into criteria under the four major evaluation dimensions. Using DEMATEL, we determined the causal relationship among different evaluation indicators and generated an influential network relation map about the evaluation criteria. Using DANP, we subsequently calculated weightings for the influence of each criterion. Finally, using the modified VIKOR, we conducted a gap analysis. The results of this study can be used to build a more positive and human reputation for correctional institutions and enable their sustainable creation.

Palliative Care Development in the Asia Pacific Region: A Review of Assessment Indicators.

CONTEXT: Organizations such as Asia Pacific Hospice Palliative Care Network functions to promote quality palliative care development through training and education, research collaboration and variety relevant projects and events for all in the Asia and Pacific region. OBJECTIVES: To summarise and further compare existing development indicators used in Asia Pacific region for palliative care. METHODS: The current review used Whittemore and Knafl 's framework for integrative reviews. PubMed, Embase, CINAHL and Google Scholar databases were searched for eligible studies. This review focused on palliative care development according to the domains and indicators identified by the World Health Organization Public Health Strategy and ATLANTES Palliative Care Research Group. Joanna Briggs Institute critical appraisal checklists were adopted to assess the methodological quality of included studies. RESULTS: Ten studies were included and two main findings were identified: 1) There was a strong evidence of educational preparation, use of medicines and service provision for palliative care development in Asia Pacific and 2) Professional activities and policy geared towards palliative care development were limited and had relative emphasis at a country-level in Asia Pacific. CONCLUSION: Palliative care development is largely influenced by policies and funding structures as well as by cultural views and beliefs of stakeholders. It is expected that individuals, stakeholders and practitioners in Asia Pacific might have differing views and cultural beliefs when compared to the European or western counterparts. The lack of details and documentation in the region and inadequate reporting measures impacts on the development of strong palliative care framework.

Differences in medical costs for end-of-life patients receiving traditional care and those receiving hospice care: A retrospective study.

BACKGROUND: Hospice care has a positive effect on medical costs. The correlation between survival time after receiving hospice care and medical costs has not been previously investigated in the literature on Taiwan. This study aimed to compare the differences in medical costs between traditional care and hospice care among end-of-life patients with cancer. METHODS: Data from Taiwan's National Health Insurance program on all patients who had passed away between 2010 and 2013 were used. Those whose year of death was between 2010 and 2013 were defined as end-of-life patients. The patients were divided into two groups: traditional care and hospice care. We then analyzed the differences in end-of-life medical cost between the two groups. RESULTS: From 2010 to 2013, the proportion of patients receiving hospice care significantly increased from 22.2% to 41.30%. In the hospice group, compared with the traditional group, the proportions of hospital stays over 14 days and deaths in a hospital were significantly higher, but the proportions of outpatient clinic visits; emergency room admissions; intensive care unit admissions; use of ventilator; use of cardiopulmonary resuscitation; and use of hemodialysis, surgery, and chemotherapy were significantly lower. Total medical costs were significantly lower. A greater number of days of survival for end-of-life patients when receiving hospice care results in higher saved medical costs. CONCLUSION: Hospice care can effectively save a large amount of end-of-life medical costs, and more medical costs are saved when patients are referred to hospice care earlier.

Controlled attenuation parameter by vibration-controlled transient elastography for steatosis assessment in members of the public undergoing regular health checkups with reference to magnetic resonance imaging-based proton density fat fraction.

AIM: Controlled attenuation parameter (CAP) measured by vibration-controlled transient elastography (FibroScan) allows repeatable and reliable assessment of liver steatosis for screening of patients at risk of non-alcoholic steatohepatitis development among asymptomatic individuals at a community level. However, this has never been compared with another quantitative method, such as magnetic resonance imaging-based proton density fat fraction, among the Chinese health checkup population. METHODS: A multicenter prospective study was conducted with Chinese individuals undergoing regular health checkups. Steatosis grading by magnetic resonance imaging-based proton density fat fraction was used as the reference to evaluate the diagnostic performance of CAP. RESULTS: A total of 173 individuals were included with mean age of 45 ± 11 years and body mass index of 25.8 ± 4.0 kg/m2 . A linear correlation was found between CAP and log10 -transformed magnetic resonance imaging-based proton density fat fraction results (Pearson's coefficient 0.772, P < 0.001). The areas under the receiver operating characteristic curve for distinguishing ≥S1 and ≥S2 steatosis were 0.88 (95% confidence interval 0.83-0.93) and 0.89 (95% confidence interval 0.83-0.95), respectively. When optimized for ≥90% sensitivity, the CAP cut-off for staging ≥S1 steatosis was 244 dB/m. CAP could classify patients with ≥S1 steatosis with similar performance as an ultrasound examination. CONCLUSIONS: As a non-invasive and quantitative method, CAP is highly adapted for population screening at a community level. With the integration of liver stiffness and CAP results in risk stratification scores for non-alcoholic steatohepatitis, vibration-controlled transient elastography can be useful in regular health checkups.

Evaluation of a Community-Run and General-Practitioner-Supervised Self-Care for Minor Illnesses (CGPSC) Program in a Remote Area in Taiwan.

Although Taiwanese citizens benefit from affordable health care, residents in remote areas extensively rely on unsafe self-care practices because of a lack of easy access to medical services. To improve self-care safety, ten easy-access self-care medical spots (ESCMSs) managed by trained residents were established in two remote villages. This study aimed to assess the impact of ESCMSs on self-care and access to medical services. For a total of six commonly experienced minor illnesses, the average number of illnesses for which residents were confident to perform self-care increased from 2.78 in the pretest to 3.58 in the post-test. ESCMSs were also the first choice when experiencing minor illnesses for 31.25% residents who did not visit a doctor. Residents' personal experience with ESCMSs correlated with their perception of ESCMSs' function. Compared with residents who had no personal experience of using ESCMSs, those who used the ESCMS service were less likely to store medications for minor illnesses at home (51.02% vs. 76.67%). Furthermore, those who attribute the reduced needs for professional help to ESCMSs had used medications for minor illnesses at ESCMSs. These results suggest that establishing ESCMSs is a viable alternative to increase the self-care capacity of residents in remote areas and increase the access to medical resources. Moreover, because residents are less likely to store medication and travel for professional help, ESCMSs could indirectly reduce the risks of self-medication and traffic accidents, respectively. However, caution should be exercised when generalizing these results to more populated areas that also lack medical resources.

Planning mass eradication of Helicobacter pylori infection for indigenous Taiwanese peoples to reduce gastric cancer.

BACKGROUND AND AIM: The aim of this study is to identify gastric cancer burden in Indigenous Taiwanese peoples and conduct a project to evaluate how to reduce the disparities most effectively in Indigenous communities. METHODS: First, we quantified the health disparities in gastric cancer in Indigenous peoples using data from the cancer registries during the period of 2006-2014. Second, we identified parameters that might be associated with Helicobacter pylori infection or help identify a good eradication strategy. RESULTS: Gastric cancer incidence (24.4 vs 12.3 per 100 000 person-years) and mortality rates (15.8 vs 6.8 per 100 000 person-years) were higher in Indigenous than in non-Indigenous, with 2.19-fold (95% confidence interval [CI]: 2.06-2.33) and 2.47-fold (2.28-2.67) increased risk, respectively. In Indigenous communities, H. pylori infection was more prevalent in Indigenous than in non-Indigenous (59.4% vs 31.5%, P < 0.01). Regression analyses consistently showed that either the mountain or plain Indigenous had 1.89-fold (95% CI: 1.34-2.66) and 1.73-fold (95% CI: 1.24-2.41) increased risk for H. pylori infection, respectively, as compared with non-Indigenous, adjusting for other baseline characteristics. The high infection rates were similarly seen in young, middle-aged, and older adults. Program eradication rates using clarithromycin-based triple therapy were suboptimal (73.7%, 95% CI: 70.0-77.4%); the habits of smoking (1.70-fold, 95% CI: 1.01-2.39) and betel nut chewing (1.54-fold, 95% CI: 0.93-2.16) were associated with the higher risk of treatment failure. CONCLUSION: Gastric cancer burden is higher in Indigenous Taiwanese peoples than in their non-Indigenous counterparts. Eliminating the prevalent risk factor of H. pylori infection is a top priority to reduce this health disparity.

Social Determinants and Disparities in Active Aging Among Older Taiwanese.

This study assesses equity in active aging across social determinants among older Taiwanese. The data were collected from face-to-face interviews with adults aged 55 years or more in Taiwan in 2017 (n = 738). A total of 30 individual-level Taiwan active aging indicators were chosen, and the relationship between social determinants and active aging indicators were analyzed by logistic regression models. Women were more likely to participate in volunteering and other social groups and in lifelong learning activities, whereas men were more likely to be employed, to engage in physical activity, to feel safe from violence, and to use preventive care. Higher education was related to higher employment, social participation, independent living, lifelong learning, and a lower likelihood of poverty and severe cognitive impairment. Those living in rural areas were more likely to be employed, perform physical activity, feel physically safe, have better mental well-being, and have higher social respect and social integration ratings, whereas living in urban areas was related to greater access to medical care, owning assets, less severe cognitive impairment, greater likelihood of using information and communications technology, higher level of education, and higher access to convenient transportation. The significant disparities that exist in active aging may suggest inequality.

Development and Validation of a Self-Assessment Tool for an Integrative Model of Health Promotion in Hospitals: Taiwan's Experience.

The Health Promotion Administration of Taiwan launched an integrative certification initiative in 2016 to streamline a plural system of certifications of health promotion in hospitals. It endeavored to replace original certifications, thereby establishing the proposal of a self-assessment instrument to aid in this integration. This study aimed to verify the robustness of this self-assessment tool by conducting exploratory factor analyses through stratification, reliability tests, content and construct validity tests, and specialist evaluations, which were convened to judge the comprehensibility, applicability, and importance of the standards and measures of this tool. A stratified random sampling of 46 hospitals was performed to confirm the validity of this tool. The tool rendered a floor effect of 0% and a ceiling effect of 13%. A valid factor structure and internal consistency (α ranged from 0.88 to 0.96) in each standard were verified. Hospitals with previous certificates or with 300+ beds achieved high compliance scores. A majority of experts agreed that the sub-standards were comprehensible (≥80%), applicable (≥70%), and important (≥70%). Finally, we conclude that the self-assessment tool is valid and can serve as a reference for other countries with hospitals committed to health promotion in hospital settings.

National health data linkage and the agreement between self-reports and medical records for middle-aged and older adults in Taiwan.

BACKGROUND: Characteristics associated with acceptance of dataset linkages and health data linkage data quality were analyzed. METHODS: Participants from the 2011 Taiwan Longitudinal Study on Aging were asked to link their epidemiological data with concurrent and future medical claim datasets. Characteristics associated with acceptance of data linkage, data consistency, under-reporting, and over-reporting of disease conditions were identified. RESULTS: Among the 3727 respondents, 3601 (96.6%) accepted data linkage. Middle-aged adults with worse functional health accepted data linkage. Older adults (65+) with better health behavior and social support were more likely to accept data linkage. Consistency between self-reports and medical data was very good to satisfactory (Kappa = 0.80 and 0.67, respectively, for diabetes and hypertension). Comorbidities were common risk factors resulting in inconsistency between self-reports and medical data (OR = 1.58 and 1.27, respectively, for diabetes and hypertension). Living alone was another risk factor resulting in inconsistency for diabetes. Male, older, and not living alone were other risk factors resulting in inconsistencies for hypertension. Under-reporting of illness was associated with poor health and older age. Over-reporting of illness was associated with better health and younger age. DISCUSSION: The findings suggest different adjustment methods for middle-aged versus older respondents when considering self-report data validity.

An anthropological approach to teach and evaluate cultural competence in medical students - the application of mini-ethnography in medical history taking.

PURPOSE: To use mini-ethnographies narrating patient illness to improve the cultural competence of the medical students. METHODS: Between September 2013 and June 2015, all sixth-year medical students doing their internship at a medical center in eastern Taiwan were trained to write mini-ethnographies for one of the patients in their care. The mini-ethnographies were analyzed by authors with focus on the various aspects of cultural sensitivity and a holistic care approach. RESULTS: Ninety-one students handed in mini-ethnographies, of whom 56 were male (61.5%) and 35 were female (38.5%). From the mini-ethnographies, three core aspects were derived: 1) the explanatory models and perceptions of illness, 2) culture and health care, and 3) society, resources, and health care. Based on the qualities of each aspect, nine secondary nodes were classified: expectations and attitude about illness/treatment, perceptions about their own prognosis in particular, knowledge and feelings regarding illness, cause of illness, choice of treatment method (including traditional medical treatments), prejudice and discrimination, influences of traditional culture and language, social support and resources, and inequality in health care. CONCLUSIONS: Mini-ethnography is an effective teaching method that can help students to develop cultural competence. It also serves as an effective instrument to assess the cultural competence of medical students.

Bayesian estimation on diagnostic performance of Face, Legs, Activity, Cry, and Consolability and Neonatal Infant Pain Scale for infant pain assessment in the absence of a gold standard.

BACKGROUND: Nonverbal pediatric patients such as infants are unable to describe their pain, which leads to the lack of a gold standard scale for their pain assessment. The aim of this study was to estimate the diagnostic performance of Face, Legs, Activity, Cry, and Consolability (FLACC) scale and Neonatal Infant Pain Scale (NIPS) for infants' pain in the absence of a gold standard. METHODS: This prospective observational study recruited 202 postoperative infants, aged <12 months. Postoperative pain intensity was evaluated using FLACC and NIPS scales. The diagnostic performance of these two scales was to estimate using a Bayesian latent class model with conditional dependence. McNemar's test was applied to test whether NIPS and FLACC tests differ from each other. RESULTS: Under a combined model with conditional dependence, the median posterior sensitivity and specificity of the FLACC were 89.94% (95% CI: 78.48-96.83%) and 87.82% (95% CI: 78.6-95.23%), respectively. The sensitivity and specificity of the NIPS were 85.94% (95% CI: 72.15-95.6%) and 92.61% (84.05-97.52%), respectively. McNemar's test demonstrated no significant difference between FLACC and NIPS in either sensitivity or specificity. CONCLUSION: Both the FLACC and NIPS have excellent sensitivity and specificity for pain assessment in infants. The comparison test showed that the FLACC scale was no different to the NIPS scale in sensitivity and specificity.

Efficacy of diclofenac sodium in pain relief after conventional radiofrequency denervation for chronic facet joint pain: a double-blind randomized controlled trial.

OBJECTIVES: Many patients experience pain for a short duration after conventional radiofrequency (CRF) denervation for lumbar facet pain. The aim of the present study was to evaluate the efficacy and cost of administering diclofenac sodium for the relief of pain after CRF denervation. METHODS: After denervation, 66 patients were randomly allocated into three groups to receive either placebo for 7 days (group A), diclofenac sodium for 3 days (group B), or diclofenac sodium for 7 days (Group C). The patients' pain visual analgesia score (VAS) and side effect were recorded at baseline 1, 7, 14, 30, and 60 days after treatment. Oswestry Disability Index (ODI), Patients' Satisfaction Score (PSS), and dosage and cost of the drugs used for pain management were recorded at baseline, 30 and 60 days after treatment. RESULTS: VAS in groups B and C both was less than that in group A at 1 and 7 days after treatment (P<0.05 and 0.01, respectively). PSS in groups B and C was significantly better than in group A at 30 and 60 days after treatment (P<0.05). The rate of side effects was similar among the three groups at all times (P>0.05). The cost of analgesic administration in group B was significantly less than in groups A and C (P<0.05). CONCLUSION: Diclofenac sodium administration improves analgesia and the PSS after CRF denervation. Compared to a 7-day dosage, a 3-day diclofenac sodium therapy has similar efficacy and less cost for the treatment of pain after CRF neurotomy.
