Chemical Constituents of Halophyte Suaeda glauca and Their Therapeutic Potential for Hair Loss.

Suaeda glauca, a halophyte in the Amaranthaceae family, exhibits remarkable resilience to high salt and alkali stresses despite the absence of salt glands or vesicles in its leaves. While there is growing pharmacological interest in S. glauca, research on its secondary metabolites remains limited. In this study, chemical constituents of the aerial parts of S. glauca were identified using 1D- and 2D-NMR experiments, and its biological activity concerning hair loss was newly reported. Eight compounds, including alkaloids (1~3), flavonoids (4~6), and phenolics (7 and 8), were isolated. The compounds, except the flavonoids, were isolated for the first time from S. glauca. In the HPLC chromatogram, quercetin-3-O-ß-d-glucoside, kaempferol-3-O-ß-d-glucoside, and kaempferol were identified as major constituents in the extract of S. glauca. Additionally, the therapeutic potential of the extract of S. glauca and the isolated compounds 1~8 on the expressions of VEGF and IGF-1, as well as the regulation of Wnt/ß-catenin signaling, were evaluated in human follicle dermal papilla cells (HFDPCs) and human umbilical vein endothelial cells (HUVECs). Among the eight compounds, compound 4 was the most potent in terms of increasing the expression of VEGF and IGF-1 and the regulation of Wnt/ß-catenin. These findings suggest that S. glauca extract and its compounds are potential new candidates for preventing or treating hair loss.

Clinical Outcomes of Operating an Acute Palliative Care Unit at a Comprehensive Cancer Center.

PURPOSE: Acute palliative care units (APCUs) are inpatient services in tertiary hospitals that provide intensive symptom management and assist in hospital discharge for transitions to hospice care. We aimed to analyze the clinical outcomes of operating an APCU at a comprehensive cancer center. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 1,440 consecutive patients admitted to the APCU and analyzed demographic and clinical information, discharge outcomes, symptom assessments using the Edmonton Symptom Assessment System, spiritual distress, and financial distress. RESULTS: The median age of patients was 67.0 (range, 23-97) years, and 41% were female. The most common primary cancer types were lung (21.9%), hepatopancreatobiliary (14.1%), and colorectal cancers (12.9%). The median length of stay was 8.0 days (range, 1-60 days), and 31.0% of patients died in the APCU. Death in the APCU showed a significant decrease over time, and overall inpatient death in oncology wards did not increase after APCU opening. In total, 44.7% of patients were discharged to government-certified hospice centers. The proportion of patients discharged to certified hospice centers increased from 32.2% in 2015 to 62.4% in 2018. Among 715 patients with a follow-up evaluation 1 week after admission, Edmonton Symptom Assessment System symptom scores, spiritual distress, and financial distress showed statistically significant improvements compared with the baseline symptom scores (P < .001). This improvement was limited to patients who did not die in the APCU. CONCLUSION: Patients with advanced cancer admitted to the APCU may experience significant improvements in distressing symptoms. The majority of patients requiring transition to hospice were successfully transferred to certified hospice centers. The percentage discharged alive improved over time.

Development of a One-item Screening Question to Assess Spiritual Well-Being for Advanced Cancer Inpatients in Korea.

CONTEXT: Spiritual well-being (SWB) is significant for patients with life-limiting illnesses. Thus, shortened versions of questions would be helpful in approaching SWB. OBJECTIVES: Our goal was to develop a one-item screening question to assess the SWB of advanced cancer inpatients. METHODS: This was a cross-sectional, multicenter study involving adult advanced cancer inpatients from seven palliative care units in South Korea. The candidate one-item questions were three questions scored using numeric rating scales from 0 to 10: feeling at peace (Are you at peace?), self-rated spirituality (Do you think of yourself as a spiritual person?), and self-rated religiosity (Do you think of yourself as a religious person?). The Functional Assessment of Chronic Illness Therapy-Spirituality 12 (FACIT-Sp-12) comprised of two subscales Meaning/Peace and Faith was used to assess SWB. Pearson's correlation test was conducted to determine the relationship between the three questions, the total FACIT-Sp-12 score, and its subscales. RESULTS: A total of 202 patients were enrolled. A strong correlation was observed between self-rated spirituality (r = 0.732 and 0.790; P < 0.001 and < 0.001 respectively) and religiosity (r = 0.708 and 0.758; P < 0.001 and < 0.001 respectively) with the total FACIT-Sp-12 scores and faith subscale scores. Feeling at peace showed a moderate correlation with the total of FACIT-Sp-12 scores (r = 0.505, P < 0.01). All three questions had a moderate correlation with the meaning/peace subscale. CONCLUSION: Self-rated spirituality and religiosity showed better convergence validity than feeling at peace. Therefore, we recommend self-rated spirituality or religiosity as a one-item question for screening SWB in inpatients with advanced cancer.

Behaviors and Attitudes toward the Use of Complementary and Alternative Medicine among Korean Cancer Patients.

PURPOSE: A cross-sectional survey was conducted to explore the current awareness and use of complementary and alternative medicine (CAM), as well as attitudes toward CAM, in patients with cancer and their family members in South Korea. MATERIALS AND METHODS: Between September 21 and October 31, 2017, a 25-item questionnaire regarding CAM experiences among cancer patients and their family members was conducted in 10 oncology clinics in South Korea after institutional review board approval at each institution. RESULTS: In total, 283/310 patients were analyzed. The median age was 60 years, and 60% were male. Most of the patients were actively receiving anticancer treatment at the time of the survey. A total of 106 patients (37%) had experienced a median of two types (interquartile range, 1 to 3) of CAM. Belief in CAM (odds ratio [OR], 3.015; 95% confidence interval [CI], 1.611 to 5.640) and duration of disease (OR, 1.012; 95% CI, 1.004 to 1.020) were independent factors for using CAM in multivariable analysis. Belief in CAM was significantly associated with current use of CAM (OR, 3.633; 95% CI, 1.567 to 8.424). Lay referral was the most common reason for deciding to use CAM, and only 25% of patients (72/283) discussed CAM with their physicians. CONCLUSION: Patient attitudes toward and confidence in CAM modalities were strongly associated with their CAM experiences, and only a small number of patients had an open discussion about CAM with their physicians. A patient education program for CAM is needed.

Spiritual Well-being Among Palliative Care Patients With Different Religious Affiliations: A Multicenter Korean Study.

CONTEXT: Spiritual well-being (SWB) is very important in palliative care patients. OBJECTIVES: The aim of this study was to investigate the SWB among palliative care patients in Korea with different religious affiliations and to identify the correlates of SWB. METHODS: This study is a cross-sectional, multicenter study involving hospitalized patients seen by palliative care teams. We collected data on basic clinicodemographic characteristics, factors related to religion (meaningful religious events, religious activities such as attending worship, individual spiritual activities such as prayer), overall quality of life, and SWB. SWB was measured using Functional Assessment of Chronic Illness Therapy-Spirituality 12. We examined the differences in SWB among patients who reported themselves as Protestants, Catholics, Buddhists, and having no religious affiliations. RESULTS: Among the 202 patients enrolled, 69 (34.2%), 48 (23.8%), 43 (21.3%), and 42 (20.8%) persons were Protestants, were Catholics, were Buddhists, and had no religious affiliation, respectively. The Functional Assessment of Chronic Illness Therapy-Spirituality 12 was highest among Protestants, followed by Catholics, Buddhists, and those without religious affiliation (29.8 vs. 27.0 vs. 23.2 vs. 16.3, P < 0.001). The faith subscale (12.4 vs. 10.4 vs. 7.7 vs. 2.5, P < 0.001) showed similar distributions. Christians reported higher SWB in the meaning and the peace subscale than patients without a religious affiliation. In the multivariate analysis, religious affiliation (P < 0.001), individual spiritual activities (P < 0.001), and quality of life (P < 0.001) were significantly related to a greater SWB. Age was inversely associated with the meaning subscale (P = 0.002). CONCLUSION: Although faith practices may be particularly helpful to improve spiritual well-being among Christians, further research is needed to determine what individual spiritual activities can support non-Christians.

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.

Practical outcome of adjuvant FOLFOX4 chemotherapy in elderly patients with stage III colon cancer: single-center study in Korea.

OBJECTIVE: Elderly patients derive similar benefits from 5-fluorouracil-based adjuvant chemotherapy in Stage III colon cancer; however, conflicting data exist regarding additional benefit from oxaliplatin, fluorouracil and leucovorin (FOLFOX) chemotherapy. METHODS: Single-center, retrospective analysis was performed to compare the safety and efficacy of adjuvant oxaliplatin, fluorouracil and leucovorin-4 chemotherapy in older patients (age ≥65 years) with younger patients with Stage III colon cancer after surgical resection. RESULTS: Among 391 patients with Stage III colon cancer, 229 patients received adjuvant oxaliplatin, fluorouracil and leucovorin chemotherapy (87 (43.5%) ≥65 years old versus 142 (74.3%) <65 years old). Older patients had similar clinico-pathological characteristics as younger patients except for higher Charlson-Age comorbidity score (median 3.44 versus 2.85, P < 0.01). The estimated 3-year disease-free survival (76.5 versus 80.0%, P = 0.88) and 3-year overall survival (90.9 versus 92.7%, P = 0.98) were similar. Grade 3-4 neutropenia was the only toxicity with higher frequency in the elderly patients (62.1 versus 46.5%, P = 0.02). Elderly patients received a lower relative dose intensity of oxaliplatin (0.76 versus 0.79) and 5-fluorouracil (0.75 versus 0.80, P = 0.009). CONCLUSIONS: Adjuvant oxaliplatin, fluorouracil and leucovorin chemotherapy resulted in similar efficacy without significant increase in toxicity in older patients aged ≥65 when compared with younger patients with curatively resected Stage III colon cancer. Therefore, for colon cancer patients aged ≥65, oxaliplatin, fluorouracil and leucovorin chemotherapy can be recommended as safe and effective adjuvant chemotherapy after curative surgery in Asia.

Identification and characterization of a novel 21.6-kDa tegumental protein from Clonorchis sinensis.

Tegumental proteins form a membrane-bound outer surface and are thus involved in host-parasite interactions and parasite survival. A complementary DNA clone encoding a novel 21.6-kDa tegumental protein (CsTegu21.6, accession number JF911532) was identified in a sequence library for the adult Clonorchis sinensis liver fluke. The complete coding sequence was 564 bp and encoded a protein of 188 amino acids. A BLASTX search revealed identities from 43 to 47% with previously identified tegumental proteins in C. sinensis and other helminthic parasites. Multiple alignment of the amino acids of CsTegu21.6 with those of four other C. sinensis tegumental proteins, CsTegu21.1, CsTegu22.3, CsTegu20.8 and CsTegu31.8, revealed pair-wise sequence identities ranging from 24 to 31.8%. A calcium-binding EF-hand domain containing a basic helix-loop-helix structure at the N terminus and a dynein light chain domain at the C terminus were found in CsTegu21.6; these motifs are common in tegumental proteins. CsTegu21.6 was specifically observed on the tegument of adult worms using immunolocalization analysis.

Patterns of palliative procedures and clinical outcomes in patients with advanced non-small cell lung cancer.

BACKGROUND: Despite recent progress in palliative chemotherapy for advanced non-small cell lung cancer (NSCLC), the prognosis is still poor. Aside from multiple lines of chemotherapy, many patients need palliative procedures due to disease-related events. The patterns of events requiring palliative procedures and their impact on the clinical course have not been well described. METHODS: We evaluated 162 patients who were diagnosed with stage IIIB (with malignant effusion) or IV NSCLC at Seoul National University Hospital in 2005. The patterns of disease-related events requiring palliative procedures, the palliative procedures given, and the clinical outcomes were retrospectively analyzed. RESULTS: Of the 162 patients, 107 were male (66%) and 55 were female (34%) with a median age of 61 years (range 31-90). Among these patients, 108 patients (66%) received palliative procedures due to disease-related events. Forty-nine patients (30%) needed a palliative procedure at the time of diagnosis, and 59 patients (36%) required palliative procedure later during the course of their treatment. The events requiring palliative procedures were thoracic events (malignant effusion or severe pneumonia requiring intensive care unit care not related to treatment) in 32 (30%), CNS events (brain metastasis or leptomeningeal metastasis) in 37 (34%), skeletal events (bone metastasis requiring radiation, spinal cord compression, hypercalcemia) in 29 (27%), and other events in 10 (9%). The patients who had events at the time of diagnosis showed comparable overall survival to the patients without events at the time of diagnosis (14.6 months vs. 13.3 months, p=0.65). The patients with later events during their course of treatment had a short median survival after the event requiring palliative procedures (median 2.7 months, 95% CI 2.19-3.21). CONCLUSION: A considerable proportion of patients with advanced NSCLC receive palliative procedures apart from chemotherapy. These interventions should be taken into consideration for comprehensive cancer care and timely cooperation with palliative care team.

Metastasis-associated protein S100A4 and p53 predict relapse in curatively resected stage III and IV (M0) gastric cancer.

PURPOSE: Pathologic stage is the most important predictive factor of relapse in gastric cancer after curative resection. However, patients with the same stage often have different risks of relapse. Here, we investigated whether the expressions of molecular markers can supplement the current staging system in terms of relapse prediction. PATIENTS AND METHODS: One hundred and nine stage III or IV (M0) patients who had received curative gastrectomy followed by adjuvant 5-fluorouracil and cisplatin chemotherapy were included in this study. The expressions of molecular markers including p53, p27, COX-2, HER-2, EGFR, maspin, S100A4, E-cadherin, Sp1, and p97 were analyzed by immunohistochemistry in cancer and paired normal tissues. RESULTS: The overall relapse rate was 58.7%, and pathologic stage was a significant predictive factor of relapse (42% in stage IIIA, 48% in IIIB, 76% in IV, p = 0.005). Of the 10 markers examined, p53 and S100A4 were expressed only in tumor tissues, and S100A4 expression was significantly associated with a higher relapse rate (85% vs. 53%, p = 0.008). In multivariate analysis including tumor stage, S100A4 and p53 expression were independent predictive factors of relapse (relative risk, 6.98; 95% confidence interval [CI], 1.608-30.342, 3.49; 95% CI, 1.328-9.186, respectively). On comparing patients who expressed S100A4 or p53 with those who expressed neither, relapse rates were 58% vs. 25% in stage III (p = 0.011) and 95% vs. 59% in stage IV (M0) (p = 0.003). CONCLUSION: In addition to staging system, the expressions of S100A4 and p53 were significant predictive factors of relapse in gastric cancer after curative resection and adjuvant chemotherapy.
