Improved Symptom Change Enhances Quality of Dying in Patients With Advanced Cancer: An East Asian Cross-Cultural Study.

BACKGROUND: Symptom burdens tend to increase for patients with cancer and their families over the disease trajectory. There is still a lack of evidence on the associations between symptom changes and the quality of dying and death. In this context, this research investigated how symptom changes influence the quality of dying and death. METHODS: This international prospective cohort study (the East Asian Collaborative Cross-Cultural Study to Elucidate the Dying Process (EASED), 2017-2019) included 22, 11, and 4 palliative care units across Japan, South Korea, and Taiwan. Eligible participants were adults (Japan and Korea, ≥18 years; Taiwan, ≥20 years) with locally advanced or metastatic cancer. Physical and psychological symptoms were assessed by physicians upon admission and within 3 days before death. Death quality was assessed using the Good Death Scale (GDS), developed in Taiwan. Univariate and multivariate regression analyses were used to identify correlations between symptom severity changes and GDS scores. RESULTS: Among 998 patients (542 [54.3%] men and 456 [45.7%] women; mean [SD] age = 70.1 [± 12.5] years), persistent dyspnea was associated with lower GDS scores when compared to stable dyspnea (ß = -0.427, 95% CI = -0.783 to -0.071). Worsened (-1.381, -1.932 to -0.831) and persistent (-1.680, -2.701 to -0.659) delirium were also significantly associated with lower GDS scores. CONCLUSIONS: Better quality of dying and death was associated with improved symptom control, especially for dyspnea and delirium. Integrating an outcome measurement for the quality of dying and death is important in the management of symptoms across the disease trajectory in a goal-concordant manner.

Cross-cultural comparison of continuous deep sedation for advanced cancer patients in East Asian countries: prospective cohort study.

OBJECTIVE: Cultural, social, and legal factors have been known to affect physicians' practice of continuous deep sedation. There have been few quantitative studies to compare continuous deep sedation practice in Asian countries. We aimed to describe and compare clinical characteristics of continuous deep sedation in Japan, Korea and Taiwan. METHODS: Patients with advanced cancer admitted to participating palliative care units were enrolled from January 2017 to September 2018. We evaluated and compared (i) the prevalence of continuous deep sedation, (ii) the characteristics of sedated and non-sedated groups in each country, and (iii) continuous deep sedation administration patterns among the three countries. RESULTS: A total of 2158 participants were included in our analysis, and 264 received continuous deep sedation. The continuous deep sedation prevalence was 10, 16 and 22% in Japan, Korea and Taiwan, respectively. Delirium was the most frequent target symptom in all countries, along with dyspnoea (in Japan) and psychological symptoms (in Korea). Midazolam was most frequently used in Japan and Taiwan, but not in Korea (P < 0.001). Among the patients receiving continuous deep sedation, the hydration amount on the final day was significantly different, with median volumes of 200, 500 and 0 mL in Japan, Korea and Taiwan, respectively (P < 0.001). In Korea, 33% of the continuous deep sedation administration caused a high degree of physicians' discomfort, but 3% in Japan and 5% in Taiwan (P < 0.001). CONCLUSIONS: Clinical practices of continuous deep sedation and physicians' discomfort related to continuous deep sedation initiation highly varied across countries. We need to develop optimal decision-making models of continuous deep sedation and hydration during continuous deep sedation in each country.

Parkin Regulates Mitosis and Genomic Stability through Cdc20/Cdh1.

Mutations in the E3 ubiquitin ligase Parkin have been linked to familial Parkinson's disease. Parkin has also been implicated in mitosis through mechanisms that are unclear. Here we show that Parkin interacts with anaphase promoting complex/cyclosome (APC/C) coactivators Cdc20 and Cdh1 to mediate the degradation of several key mitotic regulators independent of APC/C. We demonstrate that ordered progression through mitosis is orchestrated by two distinct E3 ligases through the shared use of Cdc20 and Cdh1. Furthermore, Parkin is phosphorylated and activated by polo-like kinase 1 (Plk1) during mitosis. Parkin deficiency results in overexpression of its substrates, mitotic defects, genomic instability, and tumorigenesis. These results suggest that the Parkin-Cdc20/Cdh1 complex is an important regulator of mitosis.

WSB1 promotes tumor metastasis by inducing pVHL degradation.

The von Hippel-Lindau tumor suppressor pVHL is an E3 ligase that targets hypoxia-inducible factors (HIFs). Mutation of VHL results in HIF up-regulation and contributes to processes related to tumor progression such as invasion, metastasis, and angiogenesis. However, very little is known with regard to post-transcriptional regulation of pVHL. Here we show that WD repeat and SOCS box-containing protein 1 (WSB1) is a negative regulator of pVHL through WSB1's E3 ligase activity. Mechanistically, WSB1 promotes pVHL ubiquitination and proteasomal degradation, thereby stabilizing HIF under both normoxic and hypoxic conditions. As a consequence, WSB1 up-regulates the expression of HIF-1α's target genes and promotes cancer invasion and metastasis through its effect on pVHL. Consistent with this, WSB1 protein level negatively correlates with pVHL level and metastasis-free survival in clinical samples. This work reveals a new mechanism of pVHL's regulation by which cancer acquires invasiveness and metastatic tendency.

Is spiritual well-being related to survival time of inpatients with advanced cancer? An East Asian cohort study.

OBJECTIVES: It has been suggested that psychosocial factors are related to survival time of inpatients with cancer. However, there are not many studies examining the relationship between spiritual well-being (SWB) and survival time among countries. This study investigated the relationship between SWB and survival time among three East Asian countries. METHODS: This international multicenter cohort study is a secondary analysis involving newly admitted inpatients with advanced cancer in palliative care units in Japan, South Korea, and Taiwan. SWB was measured using the Integrated Palliative Outcome Scale (IPOS) at admission. We performed multivariate analysis using the Cox proportional hazards model to identify independent prognostic factors. RESULTS: A total of 2,638 patients treated at 37 palliative care units from January 2017 to September 2018 were analyzed. The median survival time was 18.0 days (95% confidence interval [CI] 16.5-19.5) in Japan, 23.0 days (95% CI 19.9-26.1) in Korea, and 15.0 days (95% CI 13.0-17.0) in Taiwan. SWB was a significant factor correlated with survival in Taiwan (hazard ratio [HR] 1.27; 95% CI 1.01-1.59; p = 0.04), while it was insignificant in Japan (HR 1.10; 95% CI 1.00-1.22; p = 0.06), and Korea (HR 1.02; 95% CI 0.77-1.35; p = 0.89). SIGNIFICANCE OF RESULTS: SWB on admission was associated with survival in patients with advanced cancer in Taiwan but not Japan or Korea. The findings suggest the possibility of a positive relationship between spiritual care and survival time in patients with far advanced cancer.

Association between the amount of artificial hydration and quality of dying among terminally ill patients with cancer: The East Asian Collaborative Cross-Cultural Study to Elucidate the Dying Process.

BACKGROUND: Artificial hydration (AH) is a challenging issue in terminally ill patients with cancer, because it influences patients' symptoms control, quality of life, and quality of dying (QOD). To date, it is not clear how much AH supply is proper for imminently dying patients. This study aimed to investigate the association between the amount of AH and QOD. METHODS: This study is part of the East Asian Collaborative Cross-Cultural Study to Elucidate the Dying Process (EASED) conducted in Japan, Korea, and Taiwan from January 2017 to September 2018. Patients' demographics, symptoms, and managements on admission to palliative care units (PCUs) and before death were recorded. The AH amount was classified into different groups by 250-mL intervals to compare their difference. The Good Death Scale (GDS) was used to measure QOD, with patients classified into higher or lower QOD groups using GDS = 12 as the cutoff point. We used logistic regression analysis to assess the association between AH amount and QOD. RESULTS: In total, 1530 patients were included in the analysis. Country, religion, spiritual well-being, fatigue, delirium, dyspnea, AH, and antibiotics use before death were significantly associated with QOD. After conducting regression analysis, patients administered with 250 to 499 mL AH had significantly better QOD (odds ratio, 2.251; 95% confidence interval, 1.072-4.730; P = .032) than those without AH. CONCLUSIONS: AH use impacts the QOD of terminally ill patients with cancer admitted to PCUs. Communication with patients and their families on appropriate AH use has a positive effect on QOD. LAY SUMMARY: Our prospective cross-cultural multicenter study aims to investigate the relationship between artificial hydration (AH) amount and quality of dying among terminally ill patients with cancer. The findings reveal that country, religion, spiritual well-being, fatigue, delirium, dyspnea, AH, and antibiotics use before death were significantly associated with quality of death (QOD). After multivariable logistic regression, patients administered with AH amount 250 to 499 mL had significantly better QOD (odds ratio, 2.251; 95% confidence interval, 1.072-4.730; P = .032) than those without AH. Communication with patients and their families regarding AH is recommended as it may help them be better prepared for the end-of-life stage and achieve a good death.

Prevalence and severity of symptoms and signs in patients with advanced cancer in the last days of life: the East Asian collaborative cross-cultural study to elucidate the dying process (EASED).

PURPOSE: Few large-scale studies have focused on the prevalence of symptoms and signs during the last days of patients diagnosed with advanced cancer. Identifying the patterns of specific symptoms according to cancer type is helpful to provide end-of-life care for patients with advanced cancer. We investigated the prevalence and severity of symptoms and signs associated with impending death in patients with advanced cancer. METHODS: In this secondary analysis of an international multicenter cohort study conducted in three East Asian countries, we compared the severity of symptoms and signs among dying patients in the last 3 days of life according to the type of primary cancer using one-way analysis of variance (ANOVA). Post hoc analysis was conducted for multiple comparisons of each symptom according to the type of primary cancer. RESULTS: We analyzed 2131 patients from Japan, Korea, and Taiwan. The prevalence of most symptoms and signs were relatively stable from 1 week after admission to the last 3 days of life. According to cancer type, edema of the lower extremities was the most common symptom and fatigue/ ascites were the most severe symptoms in digestive tract cancer. For lung cancer, respiratory secretion was the most prevalent and dyspnea/respiratory secretion were the most severe symptoms. CONCLUSION: We demonstrated the prevalence and severity of symptoms and signs associated with the impending death of patients with advanced cancer in East Asia. Our study can enable clinicians to recognize the specific symptoms and signs at the very end of life.

Comparison of the accuracy of clinicians' prediction of survival and Palliative Prognostic Score: an East Asian cross-cultural study.

PURPOSE: No study has been conducted to compare the clinicians' prediction of survival (CPS) with Palliative Prognostic Scores (PaP) across countries. We aimed to compare the performance of the CPS in PaP (PaP-CPS), the PaP without the CPS, and the PaP total scores in patients with advanced cancer in three East Asian countries. METHODS: We compared the discriminative accuracy of the three predictive models (the PaP-CPS [the score of the categorical CPS of PaP], the PaP without the CPS [sum of the scores of only the objective variables of PaP], and the PaP total score) in patients admitted to palliative care units (PCUs) in Japan, Korea, and Taiwan. We calculated the area under the receiver operating characteristic curve (AUROC) for 30-day survival to compare the discriminative accuracy of these three models. RESULTS: We analyzed 2,072 patients from three countries. The AUROC for the PaP total scores was 0.84 in patients in Japan, 0.76 in Korea, and 0.79 in Taiwan. The AUROC of the PaP-CPS was 0.82 in patients in Japan, 0.75 in Korea, and 0.78 in Taiwan. The AUROC of the PaP without the CPS was 0.75 in patients in Japan, 0.66 in Korea, and 0.67 in Taiwan. CONCLUSION: The PaP total scores and the PaP-CPS consistently showed similar discriminative accuracy in predicting 30-day survival in patients admitted to PCUs in Japan, Korea, and Taiwan. It may be sufficient for experienced clinicians to use the CPS alone for estimating the short-term survival (less than one month) of patients with far-advanced cancer. The PaP may help to improve prognostic confidence and further reduce subjective variations.

Recovery from chronic periodontal disease is associated with lower risk for incident diabetes.

AIM: The presence of periodontal disease (PD) at a single time point has been suggested as a predictor of diabetes risk, but whether changes in PD status are associated with altered risk of diabetes is yet to be reported on a population scale. This study investigated whether recovery from or development of PD in a population is associated with an altered risk of diabetes occurrence. MATERIALS AND METHODS: Data of subjects who received health screening from 2002 to 2007 were obtained from the National Health Insurance Service-National Health Screening cohort database of Korea. Patients with a history of diabetes were excluded. Changes in PD status were determined from the first two health screenings. Study subjects were divided into four groups according to the changes in PD status: PD-free, PD-recovered, PD-developed, and PD-chronic. The outcome was the occurrence of diabetes. RESULTS: Overall, 111,611 subjects were included for analysis. During a median follow-up of 9.10 years, diabetes developed in 6102 subjects. The adjusted hazard ratios (HRs) for incident diabetes across various PD change groups (in reference to the PD-free group) were as follows: PD-chronic group = 1.096 (95% confidence interval [CI] 1.026-1.170, p = .006); PD-developed group = 1.073 (95% CI 0.993-1.159, p = .075); and PD-recovered group = 1.019 (95% CI 0.945-1.100, p = .622). The subjects who recovered from PD had a lower diabetes risk than those who had consistent PD (adjusted HR 0.930, 95% CI 0.865-1.000, p = .050), whereas those who developed PD had a higher risk of diabetes than those who remained PD-free. CONCLUSION: The longitudinal change in PD status is associated with incident diabetes risk. Future intervention studies are necessary to determine whether PD treatment can prevent incident diabetes.

Free-Living Amoeba Vermamoeba vermiformis Induces Allergic Airway Inflammation.

The high percentage of Vermamoeba was found in tap water in Korea. This study investigated whether Vermamoeba induced allergic airway inflammation in mice. We selected 2 free-living amoebas (FLAs) isolated from tap water, which included Korean FLA 5 (KFA5; Vermamoeba vermiformis) and 21 (an homolog of Acanthamoeba lugdunensis KA/ E2). We axenically cultured KFA5 and KFA21. We applied approximately 1 × 106 to mice's nasal passages 6 times and investigated their pathogenicity. The airway resistance value was significantly increased after KFA5 and KFA21 treatments. The eosinophil recruitment and goblet cell hyperplasia were concomitantly observed in bronchial alveolar lavage (BAL) fluid and lung tissue in mice infected with KFA5 and KFA21. These infections also activated the Th2-related interleukin 25, thymic stromal lymphopoietin, and thymus and activation-regulated chemokines gene expression in mouse lung epithelial cells. The CD4+ interleukin 4+ cell population was increased in the lung, and the secretion of Th2-, Th17-, and Th1-associated cytokines were upregulated during KFA5 and KFA21 infection in the spleen, lung-draining lymph nodes, and BAL fluid. The pathogenicity (allergenicity) of KFA5 and KFA21 might not have drastically changed during the long-term in vitro culture. Our results suggested that Vermamoeba could elicit allergic airway inflammation and may be an airway allergen.

"The surprise questions" using variable time frames in hospitalized patients with advanced cancer.

OBJECTIVE: Several studies supported the usefulness of "the surprise question" in terms of 1-year mortality of patients. "The surprise question" requires a "Yes" or "No" answer to the question "Would I be surprised if this patient died in [specific time frame]." However, the 1-year time frame is often too long for advanced cancer patients seen by palliative care personnel. "The surprise question" with shorter time frames is needed for decision making. We examined the accuracy of "the surprise question" for 7-day, 21-day, and 42-day survival in hospitalized patients admitted to palliative care units (PCUs). METHOD: This was a prospective multicenter cohort study of 130 adult patients with advanced cancer admitted to 7 hospital-based PCUs in South Korea. The accuracy of "the surprise question" was compared with that of the temporal question for clinician's prediction of survival. RESULTS: We analyzed 130 inpatients who died in PCUs during the study period. The median survival was 21.0 days. The sensitivity, specificity, and overall accuracy for the 7-day "the surprise question" were 46.7, 88.7, and 83.9%, respectively. The sensitivity, specificity, and overall accuracy for the 7-day temporal question were 6.7, 98.3, and 87.7%, respectively. The c-indices of the 7-day "the surprise question" and 7-day temporal question were 0.662 (95% CI: 0.539-0.785) and 0.521 (95% CI: 0.464-0.579), respectively. The c-indices of the 42-day "the surprise question" and 42-day temporal question were 0.554 (95% CI: 0.509-0.599) and 0.616 (95% CI: 0.569-0.663), respectively. SIGNIFICANCE OF RESULTS: Surprisingly, "the surprise questions" and temporal questions had similar accuracies. The high specificities for the 7-day "the surprise question" and 7- and 21-day temporal question suggest they may be useful to rule in death if positive.

Comparison of Objective Prognostic Score and Palliative Prognostic Score performance in inpatients with advanced cancer in Japan and Korea.

OBJECTIVE: Accurate prognostication is important for patients and their families to prepare for the end of life. Objective Prognostic Score (OPS) is an easy-to-use tool that does not require the clinicians' prediction of survival (CPS), whereas Palliative Prognostic Score (PaP) needs CPS. Thus, inexperienced clinicians may hesitate to use PaP. We aimed to evaluate the accuracy of OPS compared with PaP in inpatients in palliative care units (PCUs) in three East Asian countries. METHOD: This study was a secondary analysis of a cross-cultural, multicenter cohort study. We enrolled inpatients with far-advanced cancer in PCUs in Japan, Korea, and Taiwan from 2017 to 2018. We calculated the area under the receiver operating characteristics (AUROC) curve to compare the accuracy of OPS and PaP. RESULTS: A total of 1,628 inpatients in 33 PCUs in Japan and Korea were analyzed. OPS and PaP were calculated in 71.7% of the Japanese patients and 80.0% of the Korean patients. In Taiwan, PaP was calculated for 81.6% of the patients. The AUROC for 3-week survival was 0.74 for OPS in Japan, 0.68 for OPS in Korea, 0.80 for PaP in Japan, and 0.73 for PaP in Korea. The AUROC for 30-day survival was 0.70 for OPS in Japan, 0.71 for OPS in Korea, 0.79 for PaP in Japan, and 0.74 for PaP in Korea. SIGNIFICANCE OF RESULTS: Both OPS and PaP showed good performance in Japan and Korea. Compared with PaP, OPS could be more useful for inexperienced physicians who hesitate to estimate CPS.

Physical and psychological symptoms and signs in dying digestive tract cancer patients: the East Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED).

BACKGROUND: Well detection of the symptoms and signs of dying patients is essential for providing proper palliative care. Our goal is to evaluate the predominant symptoms and compare the changes in dying patients with digestive tract cancer in Japan, South Korea, and Taiwan. METHODS: A total of 1057 cancer patients aged 18 years or older admitted in palliative care units with locally advanced or metastatic gastroesophageal, colorectal, and pancreaticobiliary cancer were enrolled from January 2017 to March 2019. The severity of physical and psychological symptoms and signs assessed by physicians and/or nurses upon admission, 1 week after admission, and within 3 days of death, was compared according to cancer type and country of origin. RESULTS: Among the 338 gastroesophageal, 358 pancreaticobiliary, and 361 colorectal cancer patients, 894 (93.1%) died during the observation period. Fatigue was the most severe symptom in all cancer groups before dying. Dyspnea, fatigue, drowsiness, and ascites improved after hospitalization albeit they worsened prior to death. In particular, ascites was a marked symptom in patients with pancreaticobiliary cancer. Delirium and hallucination gradually worsened during the period leading to death. Differences in manifestations with respect to the country of origin were not significant. CONCLUSION: We identified the most prevalent signs and symptoms in patients from East Asia who were dying from digestive tract cancers. Proper management, based on these prevalent signs and symptoms during the dying period, plays a vital role in providing adequate palliative care.

Factors related to spiritual well-being in the last days of life in three East Asian countries: An international multicenter prospective cohort study.

BACKGROUND: Some factors associated with spiritual well-being in dying patients have previously been reported. However, there has been no cross-cultural study comparing factors related to spiritual well-being. The current investigation may shed light on this under-investigated area through a comparison of diverse factors. AIM: We aimed to (1) examine factors associated with spiritual well-being in the last days and (2) compare those factors across three East Asian countries. DESIGN: This is an international multicenter prospective cohort study. SETTING/PARTICIPANTS: Newly admitted inpatients with far advanced cancer in palliative care units in Japan, Korea and Taiwan were enrolled. Each patient was classified into one of two groups based on spiritual well-being score in the last days of life. Univariate and multivariate analyses were performed to identify the factors related to better spiritual well-being score in each country. RESULTS: A total of 1761 patients treated at 37 palliative care units from January 2017 to September 2018 were analyzed. Seven variables were significant in Japan, three in Korea, and five in Taiwan. "Good death scale [acceptance]," "fatigue" and "expressed wish for hastened death" were unique in Japan. "Visit from a pastoral care worker within 48 h of death" was unique in Korea. "Patient's preferences for place of death," "dyspnea" and "continuous deep sedation" were unique in Taiwan. CONCLUSIONS: This study found novel factors related to spiritual well-being in the last days of life, several of which differed according to country. Recognition of factors associated with spiritual well-being can improve the quality of palliative care.

Advance care planning in Asian culture.

Ageing has been recognized as one of the most critically important health-care issues worldwide. It is relevant to Asia, where the increasing number of older populations has drawn attention to the paramount need for health-care investment, particularly in end-of-life care. The advocacy of advance care planning is a mean to honor patient autonomy. Since most East Asian countries are influenced by Confucianism and the concept of 'filial piety,' patient autonomy is consequently subordinate to family values and physician authority. The dominance from family members and physicians during a patient's end-of-life decision-making is recognized as a cultural feature in Asia. Physicians often disclose the patient's poor prognosis and corresponding treatment options to the male, family member rather to the patient him/herself. In order to address this ethical and practical dilemma, the concept of 'relational autonomy' and the collectivism paradigm might be ideally used to assist Asian people, especially older adults, to share their preferences on future care and decision-making on certain clinical situations with their families and important others. In this review article, we invited experts in end-of-life care from Hong Kong, Indonesia, Japan, South Korea, Singapore and Taiwan to briefly report the current status of advance care planning in each country from policy, legal and clinical perspectives. According to the Asian experiences, we have seen different models of advance care planning implementation. The Asian Delphi Taskforce for advance care planning is currently undertaken by six Asian countries and a more detailed, culturally sensitive whitepaper will be published in the near future.

Establishment of metastatic liver carcinoma model by implanting AX7 cells into rabbit liver, and its histological findings.

Background: Progression of metastatic liver carcinoma from any original cancer is aggressive and the prognosis is very poor. Therefore the new model that is easily approachable to study the propagation and prognosis of metastatic liver carcinoma is necessary. The aim of this study is to confirm the tumor formation and metastatic activity of anaplastic thyroid cancer and to support the research basis for the next generation cancer treatment that is to be developed, by carrying out additional experiments like cytokine stimulation. We investigated sequential findings of immunohistochemistry of rabbit hepatic malignancy induced by AX7 cells. Methods: 13 rabbits implanted with AX7 cells directly into liver parenchyme with laparotomy were investigated by histopathology examination, immunohistochemistry, which is useful for the evaluation of metastatic cancer angiogenesis. Growing tissue at the edge of the mass was collected and placed in the petri dish filled with saline. After removing necrotic and fibrous tissue, tumor tissue was cut into pieces, placed in saline, and extracted during the experiment. Results: Tumor growth and malignancy was confirmed on the 10th day after AX7 cells were implanted into liver. Positive for VEGF staining was found in the cytoplasm or cell membrane. The scores for VEGF stained cells were moderately positive (++) on day 10, strongly positive (+++) on day 44. Ki-67-positive hepatocytes reached at 65% on day 10, at 65.78% on day 14, at 66.4% on day 30, at 67.88% on day 44. Conclusion: AX7 cells implanted into liver can be used as a new rabbit metastatic liver carcinoma model and would become useful for human metastatic liver carcinoma studies. Future studies may facilitate the establishment of an effective systemic therapy for the metastatic liver cancer.

Is spirituality related to survival in advanced cancer inpatients in Korea?

OBJECTIVE: Spirituality is what gives people meaning and purpose in life, and it has been recognized as a critical factor in patients' well-being, particularly at the ends of their lives. Studies have demonstrated relationships between spirituality and patient-reported outcomes such as quality of life and mental health. Although a number of studies have suggested that spiritual belief can be associated with mortality, the results are inconsistent. We aimed to determine whether spirituality was related to survival in advanced cancer inpatients in Korea. METHOD: For this multicenter study, we recruited adult advanced cancer inpatients who had been admitted to seven palliative care units with estimated survival of <3 months. We measured spirituality at admission using the Korean version of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-sp), which comprises two subscales: meaning/peace and faith. We calculated a Kaplan-Meier curve for spirituality, dichotomized at the predefined cutoffs and medians for the total scale and each of the two subscales, and performed univariate regression with a Cox proportional hazard model.ResultWe enrolled a total of 204 adults (mean age: 64.5 ± 13.0; 48.5% female) in the study. The most common primary cancer diagnoses were lung (21.6%), colorectal (18.6%), and liver/biliary tract (13.0%). Median survival was 19.5 days (95% confidence interval [CI95%]: 23.5, 30.6). Total FACIT-sp score was not related to survival time (hazard ratio [HR] = 0.981, CI95% = 0.957, 1.007), and neither were the scores for its two subscales, meaning/peace (HR = 0.969, CI95% = 0.932, 1.008) and faith (HR = 0.981, CI95% = 0.938, 1.026).Significance of resultsSpirituality was not related to survival in advanced cancer inpatients in Korea. Plausible mechanisms merit further investigation.

Combining virtual model and cone beam computed tomography to assess periodontal changes after anterior tooth movement.

BACKGROUND: Orthodontic force may affect not only periodontal ligaments, but also the alveoloar bone and the gingiva according to the type of tooth movements. The authors assessed changes in gingival thickness (GT) and alveolar bone thickness (ABT) after orthodontic treatment using a new method. METHODS: This study included 408 teeth (208 central incisors, 200 lateral incisors) from the upper and lower 4 anterior teeth of 52 patients who had completed orthodontic treatment. GT and ABT were measured using virtual casts fabricated from impressions and cone beam computed tomography (CBCT). Two sectioned images of every tooth axis were acquired by partitioning each tooth with a line connecting the midpoint of the incisal edge to the midpoint of the cementoenamel junction in the virtual models and the root apex in CBCT images. After superimposing the two sectioned images, GT and ABT were measured before and after orthodontic tooth movement. Correlations between GT and ABT before and after treatment, and changes in GT and ABT associated with sex, tooth arch, tooth position, orthognathic surgery, and tooth inclination and rotation were assessed. RESULTS: Before orthodontic treatment, GT and ABT were significantly correlated. Patients who underwent orthognathic surgery exhibited an increase in GT thickness compared with those who did not. ABT was significantly decreased in proclined teeth and in rotated teeth. CONCLUSIONS: GT and ABT can be affected by the nature of tooth movement and can be accurately assessed by comparing sectioned CBCT images and virtual models.
