ABSTRACT

BACKGROUND: COVID-19, the disease caused by the novel coronavirus, is now a worldwide pandemic. The number of infected people has continually increased, and currently, this pandemic continues to present challenges to public health. Scatter plots are frequently used to interpret the impact in relation to confirmed cases. However, the 95% confidence intervals are rarely given to the scatter plot. The objective of this study was to; Develop 95% control lines on daily confirmed cases and infected days for countries/regions in COVID-19 (DCCIDC) and; Examine their impacts on public health (IPH) using the hT-index.

METHODS: All relevant COVID-19 data were downloaded from GitHub. The hT-index, taking all DCCIDCs into account, was applied to measure the IPHs for counties/regions. The 95% control lines were proposed to highlight the outliers of entities in COVID-19. The hT-based IPHs were compared among counties/regions between 2020 and 2021 using the choropleth map and the forest plot. The features of the hT-index were explained using the line chart and the box plot.

RESULTS: The top 2 countries measured by hT-based IPHs were India and Brazil in 2020 and 2021. The outliers beyond the 95% confidence intervals were Hubei (China), with a lower hT-index favoring 2021 ( = 6.4 in 2021 vs 15.55 in 2020) and higher hT indices favoring 2021 in Thailand (28.34 vs 14,77) and Vietnam (27.05 vs 10.88). Only 3 continents of Africa, Asia, and Europe had statistically and significantly fewer DCCIDCs (denoted by the hT-index) in 2021. The hT-index generalizes the h-index and overcomes the disadvantage without taking all elements (e.g., DCCIDCs) into account in features.

CONCLUSIONS: The scatter plot combined with the 95% control lines was applied to compare the IPHs hit by COVID-19 and suggested for use with the hT-index in future studies, not limited to the field of public health as we did in this research.

ABSTRACT

BACKGROUND: Hypoxic-ischemic brain injury (HIBI) is a disabling consequence of cardiopulmonary resuscitation, which has no direct treatment except supportive care. Many studies have used pharmacological agents to reduce or stop this disability. MLC901 is a traditional Chinese medicine showing neuroprotective and regenerative effects on focal and global ischemia in previous animal and human studies. We designed an experimental, randomized, double-blind, placebo-controlled study to analyze MLC901 efficacy in HIBI patients.

METHODS: In a randomized, placebo-controlled trial, 35 patients with HIBI were randomly designated to receive either MLC901 or placebo capsules 3 times per day over 6 months. We assessed the 2 groups by modified Rankin Scale and Glasgow Outcome Scale at baseline, and follow-up visits in 3rd month, and 6th-month after injury.

RESULTS: Thirty-one patients completed this study. There was no significant difference in baseline characteristics between the 2 groups as regards age, gender, time of resuscitation, the interval between injury and start of the intervention, and the length of intensive care unit stay. Both the placebo and intervention groups improved during the investigation. However, the Glasgow Outcome Scale and modified Rankin Scale scales were significantly improved in the MLC901 group compared to the placebo after 6 months (P < .05) with close to no adverse effects. No major side effect was reported.

CONCLUSION: MLC901 has shown, compared to placebo, a statistically better improvement at 6 months in neurological functions of patients with HIBI.

ABSTRACT

BACKGROUND: Similarities between luteinized thecoma associated with sclerosing peritonitis (LTSP) and thecoma, cause difficulty in clinical differential diagnoses. To improve the situation, we selected 10 specified molecular pathological markers that are frequently used in clinical pathology of ovarian sex cord-stromal tumors to determine whether they exert a discriminatory effect.

METHODS: Applying immunohistochemistry, we analyzed the expression of alpha-1,6-mannosylglycoprotein 6-beta-n-acetylglucosaminyltransferase B (MGAT5B), nuclear receptor coactivator 3 (NCOA3), proliferation marker protein Ki-67 (MKI67), estrogen receptor, progesterone receptor, Vimentin, receptor tyrosine-protein kinase erbB-2, Catenin beta-1 (β-Catenin), CD99 antigen (CD99) and Wilms tumor protein (WT1) in 102 cases of diseases containing 11 LTSP and 91 thecoma. Whole-exome sequencing and fluorescence in situ hybridization were used to examine the MGAT5B-NCOA3 fusion gene in LTSP. Statistical analysis was performed using t test, one-way analysis of variance test, and post hoc test.

RESULTS: Six significant markers were verified for the discrimination between LTSP and thecoma, containing 4 upregulating indicators MGAT5B, NCOA3, MKI67, β-Catenin, and 2 downregulating markers CD99 and WT1 in luteinized cells. In addition, the MGAT5B-NCOA3 fusion gene was identified in LTSP for the first time with significantly rich expression compared to thecoma.

CONCLUSIONS: We verified 6 significant molecular pathological markers containing MGAT5B, NCOA3, MKI67, β-Catenin, CD99, and WT1 and identified MGAT5B-NCOA3 fusion gene in LTSP; this work will help clinicians to discriminate between medical conditions and treat patients accurately.

ABSTRACT

Anaemia during pregnancy is still 1 of the leading causes of maternal and neonatal mortality in low and middle-income countries. Initiatives to address this need evidence on trends and their relevant factors, as they vary from 1 area to another. This study determined the prevalence of anemia and its associated factors among pregnant women in Ilala, Tanzania. This community-based, analytical cross-sectional study was conducted in April 2022 involving 367 randomly selected pregnant women. An interviewer-administered questionnaire and a HemoCue analyzer were used for data collection The data was described using descriptive statistics (frequency distributions, percentages, etc) and inferential statistics (Chi-square tests and logistic regression) were used to explore the associations between the study’s outcome and its explanatory variables, with a significance level of P < .05. The mean age of participants was 26.2 (standard deviation = 5.2) years, 58.0% had a secondary education level, and 45.2 were prime-para. About half (57.2%) of all participants had low hemoglobin level, among which, 36.2% had moderate anemia. Having a primary education level (adjusted odds ratio [AOR] = 2.3, confidence interval [CI] = 1.1-4.7), having an inter-pregnancy interval of <18 months (AOR = 2.6, CI = 1.2-5.5), being in the third trimester (AOR = 2.4, CI = 1.2-4.7), not taking Intermittent Prophylaxis Treatment (AOR = 3.7, CI = 1.3-10), not taking iron supplement and folic acid (AOR = 3.7, CI = 1.3-10), and having a moderate appetite(AOR = 1.6, CI = 1.0-2.6) were predictors of anemia. Nutritionally related factors were not consuming on a daily basis dairy food (AOR = 3.7, CI = 1.4-9.3), meat/fish (AOR = 6.6, CI = 3-14), dark green and other vegetables (AOR = 6.6, CI = 3.1-14), fruits (AOR = 4.2, CI = 1.4-12) and having a lower dietary diversity score (AOR = 84, CI = 37-188). Approximately half of pregnant women in Ilala municipality were anemic with 1 third of them having moderate anemia. The associated factors varied from nutritional, obstetric, and socio-demographic factors. The targeted interventions should focus on health promotion campaign to sensitize the population on the dangers of anemia in pregnancy and preventive measures that must be adhered to.

ABSTRACT

BACKGROUND: Vascular dementia is a cognitive dysfunction syndrome caused by cerebral vascular factors such as ischemic stroke and hemorrhagic stroke. The effect of acupuncture on vascular dementia models is ambiguous, and there is controversy about whether acupuncture has a placebo effect. Oxidative stress and inflammation are the most essential mechanisms in preclinical studies of vascular dementia. However, there is no meta-analysis on the mechanism of vascular dementia in animal models. It is necessary to explore the efficacy of acupuncture through Meta-analysis of preclinical studies.

METHODS: Three major databases, PubMed, Embase and Web of Science (including medline), were searched in English until December 2022.The quality of the including literature was assessed using SYRCLE’s risk of bias tool. Review Manager 5.3 was used to statistically summarize the included studies and the statistical effect values were expressed by SMD. The outcomes included: behavioral tests (escape latency, number of crossings), pathological sections (Nissl and TUNEL staining), oxidative stress markers (ROS, MDA, SOD, GSH-PX) and neuroinflammatory factors (TNF-α, IL-1β, IL-6).

RESULTS: A total of 31 articles were included in this meta-analysis. The results showed that the escape latency, the contents of ROS, MDA, IL-1β, and IL-6 were decreased, and the contents of SOD and Nissl-positive neurons were increased in the acupuncture group as compared with the non-group (P < .05). Compared with the impaired group, the acupuncture group also had the above advantages (P < .05). In addition, the acupuncture group also increased the number of crossings and GSH-PX content, and decreased the expression of TUNEL-positive neurons and TNF-α (P < .05).

CONCLUSIONS: From behavioral tests to slices and pathological markers in animal models of vascular dementia, it can be proved that acupuncture is effective in targeting oxidative stress and neuroinflammatory damage, and acupuncture is not a placebo effect. Nevertheless, attention needs to be paid to the gap between animal experiments and clinical applications.

ABSTRACT

The aim of this article is to utilize ultrasound to evaluate the normal cross-sectional area (CSA)of the vagus nerve (VN) in the carotid sheath. This study included 86 VNs in 43 healthy subjects (15 men, 28 women); mean age 42.1 years and mean body mass index 26.2 kg/m2. For each subject, the bilateral VNs were identified by US at the anterolateral neck within the common carotid sheaths. One radiologist obtained 3 separate CSA measurements for each of the bilateral VNs with complete transducer removal between each measurement. Additionally, for each participant, demographic information of age and gender as well as body mass index, weight, and height were documented. The mean CSA of the right VN in the carotid sheath was 2.1 and 1.9 mm2 for the left VN. The right VN CSA was significantly larger than the left VN (P < .012). No statistically significant correlation was noted in relation to height, weight, and age. We believe that the reference values for the normal CSA of the VN obtained in our study, could help in the sonographic evaluation of VN enlargement, as it relates to the diagnosis of various diseases affecting the VN.

ABSTRACT

BACKGROUND: Empowerment education is a new nursing education model with great significance in the process of chronic disease rehabilitation, and a number of studies have found that it has good benefits for patients after percutaneous coronary intervention (PCI). But there is no meta-analysis on how empowerment education influence the life of patients after PCI.

AIMS: Our study intends to evaluate the impact of empowerment education on the quality of life, cognitive level, anxiety and depression level of patients after PCI.

DESIGN: Systematic review and meta-analysis, following PRISMA guidelines.

METHODS: RevMan5.4 software and R software were used for statistical analysis. Mean difference or standard mean difference was used as effect analysis statistic for continuous variables with 95% confidence intervals.

RESULTS: Six studies met the inclusion criteria, including 641 patients. The Exercise of Self-Care Agency Scale score of the experimental group was higher than that of the control group, with statistically significant difference. Empowerment education could increase the knowledge of coronary heart disease in patients after PCI, but the difference was not statistically significant.

CONCLUSION: Significant effects of empowerment have been found in improving patients’ quality of life and self-care ability. Empowerment education could be a safe exercise option in PCI rehabilitation. However, the effect of empowerment on cognitive level for coronary heart disease and the depression needs to carry out more large-sample, multi-center clinical trials.

ABSTRACT

The prognostic value of peripheral blood hemoglobin/red blood cell distribution width ratio (HRR) in colorectal cancer (CRC) is unclear. The aim of this study was to analyze the correlation between peripheral blood HRR and the prognosis of CRC. A retrospective study analyzed the medical records of 284 CRC patients who attended Linyi People Hospital between June 1, 2017 and June 1, 2021. The optimal diagnostic cutoff value for hemoglobin (Hb)/erythrocyte distribution width was determined by ROC curve as 3.098, and patients were divided into high- and low-level groups for comparative analysis of clinical data. Kaplan-Meier method was used for survival analysis, and logrank test was used to assess survival differences. In univariate and multifactorial analyses, Cox proportional risk regression models were used to assess independent risk factors for overall survival (OS) and progression-free survival (PFS). All statistical tests were bilateral probability tests with α = 0.05, and P < .05 was considered statistically significant. There were 284 patients who were finally included in the statistical analysis. Gender, tumor stage, Hb, platelets, and CEA were associated with PFS and OS. Tumor stage, Hb, and HRR (P < .05) were independent risk factors for PFS and OS. Low-level HRR was associated with poor patient prognosis. Low-level HRR is associated with poor patient prognosis and is a potential tumor prognostic marker.

ABSTRACT

Cardiovascular diseases (CVDs) are a leading cause of death worldwide which is why early risk prediction is crucial. Discrete Polygenic risk score (PRS) measurement using saliva or dried blood spot samples collected at home poses a convenient means for early CVD risk assessment. The present study assessed the effects of 28 disease-associated single nucleotide polymorphisms (SNPs) on 16 serological cardiac markers and also aggregated the risk alleles into a PRS to evaluate its applicability in CVD-risk prediction. The study assessed genetic and serological markers in 184 individuals. The association between serological markers and individual genetic variants was evaluated using a two-tailed t test while the associations of serum markers with the PRS was analyzed using the Pearson correlation. The comparative analysis of genotypes revealed statistically significant associations between serum markers and CVD-associated SNPs with Apo B: Apo A-1, LDL Direct, Apo B, sdLDL, hsCRP, Lp(a), NT-proBNP, and PLAC levels being significantly associated with the risk alleles of the SNPs, rs12526453, rs5186, rs10911021, rs1801131, rs670, rs10757274, and rs10757278. Increased PLAC levels were associated with rs10757274 and rs10757278 (P < .05). The SNPs, rs1801133, rs1549758, rs1799983, rs5082, and rs5186 were significantly associated with an increase in the cardioprotective markers, HDL and ApoA1 (P < .05). Furthermore, the PRS was associated with increasing levels of several serum cardiac markers (r2 > 0.6). Significant correlations were observed between high PRSs and NT-proBNP and ox-LDL levels with the r2 values being 0.82 (95% CI = 0.13-0.99; P = .03) and 0.94 (95% CI = 0.63-0.99; P = .005), respectively. The present study reports that SNPs have differential effects on serum markers with rs12526453, rs5186, rs10911021, rs1801131, rs670, rs10757274, and rs10757278 showing significant associations with elevated marker levels, which are indicators of deteriorating cardiac health. A unified PRS using several SNPs was also associated with an increase in serum markers levels, especially, NT-proBNP and ox-LDL. Genetic assessment via a convenient at-home collection to calculate the PRS can serve as an effective predictive tool for early CVD-risk assessment. This may help identify the risk groups that may require increased serological monitoring.

ABSTRACT

BACKGROUND: Rheumatoid arthritis is a chronic inflammatory autoimmune disease characterized by a wide range of clinical symptoms affecting various bodily functions, including skeletal, vascular, metabolic, and cognitive functions. This review aimed to evaluate the efficacy and safety of integrative medicine (East Asian herbal medicine combined with conventional medicine) used for the treatment of inflammatory pain in rheumatoid arthritis and to identify key candidate drugs based on the data.

METHODS: A comprehensive literature search will be conducted in 4 core databases (PubMed, Excerpta Medica database, Cochrane Library, and Cumulative Index to Nursing & Allied Health Literature) 4 Korean databases (Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, Research Information Service System, and Korea Citation Index), 2 Chinese databases (Chinese National Knowledge Infrastructure Database and Wanfang data), and 1 Japanese database (Citation Information by National Institute of Informatics) for randomized controlled trials from December 13, 2022. Statistical analysis will be performed using R version 4.1.2 and R Studio program. The American College of Rheumatology 20/50/70 score and rate of adverse events will be the primary outcomes. All outcomes will be analyzed using a random-effects model to produce more statistically conservative results. Sensitivity, meta-regression, and subgroup analyses will be used to identify the sources of any heterogeneity in the study. The revised tool for assessing the risk of bias in randomized trials, version 2.0, will be used to evaluate methodological quality. The overall quality of evidence will be assessed according to the Grading of Recommendations Assessment, Development, and Evaluation Pro Framework.

ETHICS AND DISSEMINATION: There are no ethical issues, as no primary data will be collected directly from the participants. The results of this review will be reported in a peer-reviewed scientific journal.

TRIAL REGISTRATION: PROSPERO registration number: CRD42023412385.
