METHODS: Published journals before September 2021, from five databases (PubMed, ScienceDirect, Springer, Cochrane, and CNKI) were retrieved according to the keywords. The keywords used included cancer patients, terminally ill patients, cancer, SPB, self-perceived burden, self-burden, self-perceived, factor, predictor, associated factor, determinants, risk factor, prognostic factor, covariate, independent variable, and variable. The quality of the inclusion and exclusion criteria was independently reviewed by three researchers.
RESULTS: Out of 12,712 articles, there are 22 studies met the eligibility criteria. The prevalence of SPB among cancer patients ranged from 73.2 to 100% in Malaysia, China, and Canada. Most of them had moderate SPB. Out of the reported factors, age, gender, marital status, ethnicity, residence, educational level, occupational status, family income, primary caregiver, payment methods, disease-related factors, psychological factors, and physical factors were mostly reported across the studies.
CONCLUSIONS: In conclusion, SPB prevalence is high in cancer patients. Therefore, hospitals, non-governmental organizations, relevant policymakers, and communities can provide special programs for high-risk groups to provide psychological guidance or design corresponding interventions to reduce the SPB level of patients and improve the quality of life.
METHODS: This study enumerated the abundance of E. coli in the water and sediment at five urban lakes in the Kuala Lumpur-Petaling Jaya area, state of Selangor, Malaysia. We developed a novel method for measuring habitat transition rate of sediment E. coli to the water column, and evaluated the effects of habitat transition on E. coli abundance in the water column after accounting for its decay in the water column.
RESULTS: The abundance of E. coli in the sediment ranged from below detection to 12,000 cfu g-1, and was about one order higher than in the water column (1 to 2,300 cfu mL-1). The habitat transition rates ranged from 0.03 to 0.41 h-1. In contrast, the E. coli decay rates ranged from 0.02 to 0.16 h-1. In most cases (>80%), the habitat transition rates were higher than the decay rates in our study.
DISCUSSION: Our study provided a possible explanation for the persistence of E. coli in tropical lakes. To the best of our knowledge, this is the first quantitative study on habitat transition of E. coli from sediments to water column.
AIM OF THE STUDY: To investigate the anti-angiogenic mechanism of EC and its anti-tumor effect by suppressing angiogenesis.
MATERIALS AND METHODS: The in vitro anti-angiogenic effect was evaluated using HUVECs model induced by VEGF and zebrafish model in vivo. The influence of the EC on phosphorylation of VEGFR2 and its downstream signaling pathways were evaluated by western blotting assay. Molecule docking technology was conducted to explore the interaction between EC and VEGFR2. SPR assay was used for detecting the binding affinity between EC and VEGFR2. To further investigate the molecular mechanism of EC on anti-angiogenesis, VEGFR2 knockdown in HUVECs and examined the influence of the EC. Anti-tumor activity of EC was evaluated using colony formation assay and apoptosis assay. The inhibitory effect of EC on tumor growth was explored using HT29 colon cancer xenograft model.
RESULTS: EC obviously inhibited proliferation, migration, invasion and tube formation of VEGF-induced HUVECs. EC also induced apoptosis of HUVECs. Moreover, it inhibited the development of vessel formation in zebrafish. Further investigations demonstrated that EC could suppress the phosphorylation of VEGFR2, and its downstream signaling pathways were altered in VEGF-induced HUVECs. EC formed a hydrogen bond to bind with the ATP binding site of the VEGFR2, and EC-VEGFR2 interaction was shown in SPR assay. The suppressive effect of EC on angiogenesis was abrogated after VEGFR2 knockdown in HUVECs. EC inhibited the colon cancer cells colony formation and induced apoptosis. In addition, EC suppressed tumor growth in colon cancer xenograft model, and no detectable hepatotoxicity and nephrotoxicity. In addition, it inhibited the phosphorylation of VEGFR2, and its downstream signal pathways in tumor.
CONCLUSIONS: EC could inhibit tumor growth in colon cancer by suppressing angiogenesis via VEGFR2 signaling pathway, and suggested EC as a promising candidate for colon cancer treatment.
METHODS: This is an open-label randomized controlled trial with 60 participants divided into 2 study groups in a 1:1 ratio. The intervention group will receive 12 weeks of Guolin Qigong intervention with a 4-week follow-up while control will receive usual care under waitlist. The primary outcome will be feasibility measured based on recruitment and retention rates, class attendance, home practice adherence, nature, and quantum of missing data as well as safety. The secondary subjective outcomes of fatigue, sleep quality and depression will be measured at Week-1 (baseline), Week-6 (mid-intervention), Week-12 (post-intervention), and Week-16 (4 weeks post-intervention) while an objective 24-hour urine cortisol will be measured at Week-1 (baseline) and Week-12 (post-intervention). We will conduct a semi-structured interview individually with participants within 3 months after Week-16 (4 weeks post-intervention) to obtain a more comprehensive view of practice adherence.
DISCUSSION: This is the first mixed-method study to investigate the feasibility and effect of Guolin Qigong on breast, lung, and colorectal cancer survivors to provide a comprehensive understanding of Guolin Qigong's intervention impact and participants' perspectives. The interdisciplinary collaboration between Western Medicine and Chinese Medicine expertise of this study ensures robust study design, enhanced participant care, rigorous data analysis, and meaningful interpretation of results. This innovative research contributes to the field of oncology and may guide future evidence-based mind-body interventions to improve cancer survivorship.
TRIAL REGISTRATION: This study has been registered with ANZCTR (ACTRN12622000688785p), was approved by Medical Research Ethic Committee of University Malaya Medical Centre (MREC ID NO: 2022323-11092) and recognized by Western Sydney University Human Research Ethics Committee (RH15124).
METHODS: We systematically searched Pubmed for population-based studies of chronic kidney disease (CKD) and ESKD epidemiology and management. Population-level data from 23 pre-designated nations were eligible for inclusion if they pertained to people receiving dialysis or kidney transplant for ESKD. When available, government websites were utilized to identify and extract data from relevant kidney registries . Measures gathered included those related to the prevalence and mortality of ESKD; the availability of nephrologists; per capita healthcare expenditures; and use of erythropoietin stimulating agents (ESAs).
RESULTS: We obtained data from the United States (US), 7 nations in Eastern Europe, 4 each in Western Europe, Latin America, and Africa, and 3 in Asia. Documented prevalence of ESKD per million population varied from a high of 3,600 (Malaysia) to a low of 67 (Senegal). Annual mortality associated with ESKD varied from 31% (Ethiopia and Senegal) to 10% (UK). Nephrologist availability per million population varied from 40 (Japan) to <1 (South Africa) and was associated with per capita healthcare expenditures.
CONCLUSIONS: The delivery of kidney care related to ESKD varies widely among countries. Higher per capita healthcare spending is associated with increased delivery of kidney care. However, in part because documentation of kidney disease varies widely, it is difficult to determine how outcomes related to ESKD may vary across nations.
