Objective The coronavirus disease 2019 (COVID-19) pandemic has had a serious impact on health all over the world. Cancer patient, whose immunity is often compromised, faces a huge challenge. Currently, some COVID-19 vaccines are being developed and applied on general population; however, whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China. Methods A cross-sectional study was conducted in Eastern China from June 17th to September 3rd, 2021. Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine; following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance. Results A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05% (519/2158); further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine (35.54%), and 872 were willing to get vaccinated (40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants, patients’ knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the “vaccine hesitancy” population and “vaccine acceptance” population. Multivariate logistic regression analysis indicated that parameters including alcohol consumption (odds ratio [OR] = 1.849; 95% confidence interval [CI]: 1.375–2.488; P -reference [ P -Ref] < 0.001 vs non-drinkers), income impacted by COVID-19 pandemic (OR = 1.930, 2.037 and 2.688 for mild, moderate, and severe impact, respectively; all P -Ref < 0.01 vs no impact), knowledge of how the vaccine was developed (OR = 1.616; 95% CI: 1.126–2.318; P -Ref = 0.009 vs unknown), believing in the safety of the vaccine (OR = 1.502; 95% CI: 1.024–2.203; P -Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine (OR = 3.042; 95% CI: 2.376–3.894; P -Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated (OR = 2.744; 95% CI: 1.759–4.280; P -Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired (OR = 0.586; 95% CI: 0.438–0.784; P -Ref < 0.001 vs...
The global monkeypox outbreak in 2022 has severely affected the life and health of people. Currently, partial smallpox vaccines have been approved for monkeypox prevention. Considering the potential occupational health risks of monkeypox infection among healthcare workers (HCWs), this study explored the willingness of Chinese HCWs to receive the monkeypox vaccine and analyzed the factors influencing their decision. We conducted an online cross‐sectional survey among HCWs of 10 Chinese hospitals from May 30th, 2022 to August 1st, 2022. Specifically, a self‐report questionnaire was administered to evaluate the attitude and acceptance of HCWs toward the monkeypox vaccine, followed by a multivariate logistic regression analysis to determine the independent predictors of vaccination. The survey included 1032 participants, of whom 90.12% expressed their willingness for vaccination (vaccine hesitancy rate = 9.88%). Univariate analysis showed that 11 variables differed significantly between the vaccine acceptance and vaccine hesitancy groups. Multivariate logistic regression analysis demonstrated that the age of 30–40 years (odds ratio [OR] = 0.504, 95% confidence interval [CI]: 0.284–0.893, p = 0.019 vs. age of <30 years old), working in a secondary hospital (OR = 0.449, 95% CI: 0.249–0.808, p = 0.019 vs. working in a tertiary hospital), considering vaccination necessary for controlling monkeypox infection (OR = 4.135, 95% CI: 2.109–8.106, p < 0.001 vs. not considering it necessary), willingness to pay for the monkeypox vaccine (OR = 2.125, 95% CI: 1.206–3.745, p = 0.009 vs. no willingness to pay), considering implementation of mandatory vaccination necessary (OR = 1.990, 95% CI: 1.023–3.869, p = 0.043 vs. not considering it necessary), and recommending family members and friends to take the vaccine (OR = 13.847, 95% CI: 7.487–25.609, p < 0.001 vs. not recommending) were crucial independent predictors of the willingness to receive monkeypox‐related vaccination. This study evaluated the acceptance and hesitancy rates of Chinese HCWs toward the monkeypox vaccine and found that the willingness to receive vaccination was mainly correlated to age, hospital level, and attitude toward vaccination. Therefore, to promote vaccine absorption, we recommend expanding publicity, formulating reasonable policies, and improving the recognition of vaccines.
BackgroundThis study aimed to investigate the association of serum concentrations of vitamin A, D, and E with recurrent respiratory tract infections (RRTIs).MethodsA total of 1200 children aged at 0.5–14 years were selected via a face-to-face survey in Harbin, China. Among the participants, 600 children with RRTIs comprised the symptomatic group (RRTI group), whereas 600 healthy children were used as controls (control group). Blood samples were collected to measure serum levels of vitamins A and E by HPLC; the serum level of 25-hydroxycholecalciferol (25(OH)D), was measured by HPLC-MS/MS.ResultsSerum levels of vitamins A and E, as well as 25(OH)D, were significantly lower in the RRTI group than the control group. The conditional logistic regression model and the receiver-operating characteristic curve showed that the insufficiency or deficiency of vitamins A, D, and E was positively correlated with RRTI occurrence (p < 0.05).ConclusionsLow serum concentrations of vitamins A, D, and E were associated with RRTIs in children from northern China.
Background Living at high latitudes is one of the risk factors for vitamin D deficiency in children. However, evidence on vitamin D improvement for this pediatric population to date is limited. This study aims at evaluating the association of different vitamin D intervention methods and outdoor activity on the vitamin D status of children in North China. Methods In this observational study, a total of 55,925 children aged 1 month to 18 years old were recruited from pediatric outpatient departments from July 2016 to June 2017. Data on demographics, anthropometric measurements, vitamin D intervention (either prescribed by physicians or given by parents) and outdoor activity were recorded. The serum levels of 25-hydroxycholecalciferol (25(OH)D) were determined by high performance liquid chromatography tandem–mass spectrometry. Logistic regression analysis was performed to assess the association of vitamin D intervention or outdoor activity with blood vitamin D status, adjusted for age, gender, BMI for age, and seasons. Results The overall rate of hypovitaminosis D was 65.60%. Of the children’s outdoor activity, 35.63, 31.95, and 32.42% were below 30 min/d, 30–60 min/d and over 60 min/d, respectively. Furthermore, the proportion of therapeutic intervention, supplementation intervention and no vitamin D intervention among the children was 16.48, 32.87, and 50.65%, respectively. After adjusted for confounding factors, vitamin D intervention was associated with a lower risk of hypovitaminosis D, with OR (95% CI) of 0.191 (0.180, 0.202) in children with therapeutic doses and 0.423 (0.404, 0.443) in those with supplementation doses, compared with children without vitamin D intervention. In addition, longer outdoor time was associated with a lower risk of hypovitaminosis D [0.479 (0.456, 0.504) for 60 min/d, 0.737 (0.701, 0.776) for 30–60 min/d], independent of vitamin D intervention. Conclusions High prevalence of vitamin D deficiency was found in children living at high latitudes. Vitamin D intervention and outdoor activity are all negatively associated with children’s vitamin D deficiency. Routine vitamin D intervention combined with increased outdoor time might be an effective approach to prevent hypovitaminosis D among children, especially those at school, living at high latitudes.
Use of the TCM four diagnostic methods can provide an effective basis for TCM syndrome diagnosis, observation of development of state of illness, and evaluation of clinical therapeutic effects.
Background and Objective. Acute liver failure (ALF) is a rare clinical syndrome with a poor prognosis and leads to multiple organ failure. Polygoni Cuspidati Rhizoma et Radix (PCRR) is a commonly used Chinese medicine, which is recognized as a potential therapeutic herb against ALF. This study aimed to explore the pharmacological mechanisms of the therapeutic effect of PCRR in ALF via network pharmacology and molecular docking. Materials and Methods. The potential bioactive compounds of PCRR and their targets were collected from TCMSP, TCMID, and BATMAN-TCM databases with absorption, distribution, metabolism, and excretion protocols (oral bioavailability ≥30% and drug-likeness ≥0.18). The ALF-related target genes were identified using the GeneCards and OMIM databases. A protein-protein interaction (PPI) network among these targets was constructed using the Cytoscape software to obtain the core targets. The genes associated with ALF were analyzed via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses to identify the signaling pathways related to the therapeutic effect of PCRR in ALF. Results. In total, 10 bioactive compounds of PCRR and 200 targets related to them were obtained, and 2913 ALF-related target genes were identified. PPI network analysis pinpointed 15 core targets, namely, TP53, AKT1, JUN, HSP90AA1, MAPK1, RELA, TNF, ESR1, IL6, MYC, MAPK14, FOS, RB1, CDKN1A, and EGFR. GO enrichment and KEGG pathway analyses revealed that the therapeutic mechanisms of PCRR in ALF are related to cell metabolism, oxidative stress, inflammation, and hepatocyte apoptosis. Conclusion. This is the first study to explore the therapeutic mechanisms of PCRR in ALF via network pharmacology and molecular docking. This study provides a research platform with candidate ALF-related targets of PRCC for the development of therapeutics against ALF.
Objective The Coronavirus Disease 2019 (COVID-19) has brought severe damage to global health and socioeconomics. In China, traditional Chinese medicine (TCM) is the most important complementary and alternative medicine (CAM) and it has shown a beneficial role in the prevention and treatment of COVID-19. However, it is unknown whether patients are willing to accept TCM treatment. The objective of our study is to investigate the acceptance, attitude, and independent predictors of TCM among asymptomatic COVID-19 patients admitted to Shanghai fangcang hospital during the outbreak of the COVID-19 pandemic in Shanghai in 2022. Methods A cross-sectional study was conducted on asymptomatic COVID-19 patients in the largest fangcang hospital in Shanghai, China, from April 22, 2022, to May 25, 2022. Based on the literature review of previous similar studies, a self-report questionnaire was developed to assess the patients’ attitude and acceptance of TCM, and a multivariate logistic regression analysis was conducted to determine the independent predictors of TCM acceptance. Results A total of 1,121 patients completed the survey, of whom 91.35% were willing to accept CAM treatment whereas 8.65% of participants showed no willingness. Multivariate logistic regression analysis revealed that the patients who have received two doses of COVID-19 vaccine (OR = 2.069, 95%CI: 1.029–4.162, P = 0.041 vs. not received), understood the culture of TCM (OR = 2.293, 95%CI: 1.029–4.162, P = 0.014 vs. not understood), thought the TCM treatment is safe (OR = 2.856, 95%CI: 1.334–6.112, P = 0.007 vs. not thought), thought the TCM treatment is effective (OR = 2.724, 95%CI: 1.249–5.940, P = 0.012 vs. not thought), and those who informed their attending physician if using TCM for treatment (OR = 3.455, 95%CI:1.867–6.392, P < 0.001 vs. not informed) were more likely to accept TCM treatment. However, patients who thought TCM might delay your treatment (OR = 0.256, 95%CI: 0.142–0.462, P < 0.001 not thought) was an independent predictor for unwillingness to accept TCM treatment. Conclusion This study preliminarily investigated the acceptance, attitude, and predictors of intention to receive TCM among asymptomatic COVID-19 patients. It is recommended to increase the publicity of TCM, clarify the impact of TCM and communicate with attending doctors that meet the healthcare needs of asymptomatic COVID-19 patients.
This study examined the effects of different duration of stress exposure on cellular immunity and heat shock protein (HSP) 70 expression in rats. The different durations of crowding and noise were used as different stress modes. Observation of exploratory behavior in an open‐field test was used to indicate stress level. The expression of HSP70 and T‐cell subsets in blood samples were measured in the different groups of stressed rats. The results showed that there were significant reductions in the percentages of CD3+ and CD4+ T cells in the stressed groups. The lowest point was at 2 weeks from stress. There were significant increases in the percentage of CD8+ in 2 day, 1 week and 2 week stress groups compared with the control group. The CD4+/CD8+ ratio was also remarkably lower in rats of the 2 day, 1 week and 2 week stress groups compared with the control group. HSP70 expression rose significantly after stress and reached a maximum after 2 weeks of stress. Open field test activity showed higher vertical movement scores at 2 weeks stress compared with the control group. Grooming scores at 2 days stress was obviously more than that of the control and there were higher grooming scores at 2 weeks and 3 weeks stress compared to the 2 day stress group. Those results showed that the different duration stress exposure affects both exploratory behavior and immune function. The results also showed that not only immune function but also HSP70 expression was mainly dependent on the duration of stress. Copyright © 2006 John Wiley & Sons, Ltd.
