Association of plasma high-density lipoprotein cholesterol level with risk of stress urinary incontinence in women: a retrospective study.

BACKGROUND: Studies have found that high density lipoprotein cholesterol (HDL-C) levels are linked to a variety of diseases. However, evidence for the relationship between stress urinary incontinence (SUI) and HDL-C remain limited. METHODS: 590 eligible women were enrolled. Basic characteristic, gynecological examinations and blood sampling were collected. The examination of the possible link between HDL-C and SUI was done using univariate and multivariate logistic regression. Feature importance ranking and Receiver operating characteristic (ROC) curves were performed to further evaluate the association between HDL-C and SUI in women. RESULTS: A significant association was found between HDL-C and SUI in women, revealing higher HDL-C levels were related to a lower risk of SUI (OR 0.238; 95%CI: 0.091-0.623; P < 0.01) after adjustment for potential key confounders. The AUC for the SUI predicted by the combined HDL-C was 0.845 (95%CI: 0.798-0.891, P < 0.001). The feature importance ranking revealed that vaginal delivery, HDL-C were the top two important factors. CONCLUSIONS: HDL-C levels were correlated with the development of SUI. In addition to physical and surgical treatments, HDL-C may offer the possibility of potential targeted treatment and prevention of SUI afterwards.

Plasma 25-hydroxyvitamin D deficiency in the peri-operative period is associated with survival outcome in colorectal cancer patients: a meta-analysis.

AIM: Surgery had a significant impact on 25-hydroxyvitamin D (25-(OH)D) levels. Uncertainty still existed regarding the effects of peri-operative 25(OH)D deficiency on colorectal cancer (CRC) patients' prognosis. The purpose of the present study was to explore the potential association between the peri-operative 25(OH)D deficiency and the survival outcome of CRC. METHODS: Seven electronic databases [including PubMed, EMBASE, Web of Science, The Cochrane Library, OvidMEDLINE(R), China National Knowledge Infrastructure (CNKI) and Wangfang data] were searched without language limitations. The primary outcomes were overall survival and all-cause mortality. Secondary outcomes were the incidence of 25(OH)D deficiency and risk variables for low 25(OH)D level in the peri-operative period. RESULTS: 14 eligible studies were obtained with 9324 patients for meta-analysis. In the peri-operative period, the pooled incidence of blood 25(OH)D deficiency was 59.61% (95% CI: 45.74-73.48). The incidence of blood 25(OH)D deficiency post-operatively (66.60%) was higher than that pre-operatively (52.65%, 95% CI: 32.94-72.36). Male (RR = 1.09, 95% CI: 1.03-1.16), rectum tumor (RR = 1.23, 95% CI: 1.03-1.47), spring and winter sampling (RR = 1.24, 95% CI: 1.02-1.49) were the risk factors for the 25(OH)D deficiency. The association between the low 25(OH)D post-operatively and short-term overall survival (HR = 0.43, 95% CI: 0.24-0.77) was most prominent, while a low 25(OH)D pre-operatively (HR = 0.47, 95% CI: 0.31-0.70) was more significantly associated with long-term all-cause mortality than that after surgery. CONCLUSION: Peri-operative 25(OH)D impacted the CRC patients' prognosis. Due to possible confounding effects of systemic inflammatory response (SIR), simultaneous measurement of vitamin D and SIR is essential for colorectal survival.

Using the '4Ps' social marketing strategy to overcome vaccination hesitancy: COVID-19 vaccine coverage in a Chinese college as an example.

OBJECTIVES: To explore the role of the '4Ps' social marketing strategy on vaccine hesitancy and its impact on public vaccine coverage. The '4Ps' strategy (place, price, product and promotion) is a social marketing tool that had addressed many public issues and vaccinations. METHODS: This study was a retrospective before-after study. A total of 10795 people were enrolled. The routine COVID-19 immunization method was used for the first vaccination doses from 23 March to 11 April, 2021. Then we carried out a '4Ps' social marketing strategy for vaccination from 12 April to 1 May 2021. The vaccine hesitancy and the coverage rate of the first dosage of COVID-19 vaccine in the target population were collected and compared before and after the '4Ps' social marketing strategy. RESULTS: The coverage reached only 6.19% during routine immunization. However, vaccine hesitancy of the target population decreased (52% versus [vs.] 3.1%, before vs. after '4Ps' strategy) and degree of coverage (94.8%, vs. routine vaccination method, p<0.001) significantly increased after taking '4Ps' social marketing strategy. Furthermore, the '4Ps' social marketing strategy also consolidated the completion of the second dosage of COVID-19 vaccines. CONCLUSION: The '4Ps' social marketing strategy greatly reduced vaccine hesitancy and enhanced vaccination coverage and provided a more effective and reliable promotion method in the face of current virus mutations and new vaccination in the future.

Pretreatment Depressive Status Associated with Poor Nutrition and Prognosis in Breast Cancer Patients Receiving Neoadjuvant Chemotherapy.

The prevalence of pretreatment depression in breast cancer patients and its impact on nutrition and prognosis during neoadjuvant chemotherapy remain unknown. One hundred twenty-one patients with previously untreated breast cancer undergoing neoadjuvant chemotherapy (NAC) were enrolled. Patients completed the Self-rating Depressive symptoms Scale (SDS) before treatment and were divided into two groups (non-depressive group and depressive group). The nutrition risk screening-2002 (NRS-2002), and nutritional and prognostic indicators, including neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI), were collected at baseline (pretreatment) and post-treatment. One- and two-year progression-free survival (PFS) in both groups were also calculated. We found that 38.84% patients experienced pretreatment depressive symptoms. Patients in the depressive group had higher nutritional risk and lower body mass index, potassium, sodium, total cholesterol, total protein, and fasting blood glucose levels than those in pretreatment non-depressive group after NAC (all p < 0.05). And higher NLR (p = 0.039) and lower PNI level (p = 0.0021) after NAC were found in patients with pretreatment depressive status. Multivariable Cox analysis showed pretreatment depressive status (HR: 1.893; 95% CI: 1.047-3.426; p = 0.034) were a significant predictor of PFS. This study provides evidence for early identification of pretreatment depression in patients receiving NAC, which would certainly favor nutrition and survival outcome.

Predictors of Psychological Distress among Patients with Colorectal Cancer-Related Enterostomy: A Cross-sectional Study.

OBJECTIVE: To identify variables that may predict psychological distress in patients with an enterostomy. METHODS: Investigators recruited 77 patients with a stoma from a stoma clinic according to the inclusion criteria. Patients' psychological distress was assessed with the Distress Thermometer (DT) tool, and their personality type was determined by the Eysenck Personality Questionnaire. Researchers also collected demographic and disease-related data. Predictive values were estimated using multiple regression analyses. RESULTS: The mean DT score of all patients was 5.94 (SD, 1.81), and approximately 85.7% consistently suffered from psychological distress. Being unmarried and having peristomal complications were associated with higher psychological distress, whereas having a monthly income 5,000 ¥ or more was associated with lower levels of distress. Moreover, patients with a melancholic personality type tended to have higher DT scores, which could act as a strong independent predictor for psychological distress. CONCLUSIONS: The majority of patients with a stoma endured moderate to severe psychological distress during follow-up care. Exploring the related factors that predict the levels of psychological distress could enable clinicians to identify at-risk patients as early as possible and thus provide optimal care for improving patients' quality of life.

ERG-Associated lncRNA (ERGAL) Promotes the Stability and Integrity of Vascular Endothelial Barrier During Dengue Viral Infection via Interaction With miR-183-5p.

Dengue virus (DENV) continues to be a major public health problem. DENV infection will cause mild dengue and severe dengue. Severe dengue is clinically manifested as serious complications, including dengue hemorrhagic fever and/or dengue shock syndrome (DHF/DSS), which is mainly characterized by vascular leakage. Currently, the pathogenesis of severe dengue is not elucidated thoroughly, and there are no known therapeutic targets for controlling the disease effectively. This study aimed to further reveal the potential molecular mechanism of severe dengue. In this study, the long non-coding RNA, ERG-associated lncRNA (lncRNA-ERGAL), was activated and significantly up-regulated in DENV-infected vascular endothelial cells. After knockdown of lncRNA-ERGAL, the expression of ERG, VE-cadherin, and claudin-5 was repressed; besides, cell apoptosis was enhanced, and cytoskeletal remodeling was disordered, leading to instability and increased permeability of vascular endothelial barrier during DENV infection. Fluorescence in situ hybridization (FISH) assay showed lncRNA-ERGAL to be mainly expressed in the cytoplasm. Moreover, the expression of miR-183-5p was found to increase during DENV infection and revealed to regulate ERG, junction-associated proteins, and the cytoskeletal structure after overexpression and knockdown. Then, ERGAL was confirmed to interact with miR-183-5p by luciferase reporter assay. Collectively, ERGAL acted as a miRNA sponge that can promote stability and integrity of vascular endothelial barrier during DENV infection via binding to miR-183-5p, thus revealing the potential molecular mechanism of severe dengue and providing a foundation for a promising clinical target in the future.

An increasing public health burden arising from children infected with SARS-CoV2: A systematic review and meta-analysis.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) is spreading all over the world and poses a great threat to humans. This study aimed to systematically review the current situation and public health burden associated with children infected with SARS-CoV2. METHODS: We searched four electronic databases without language limitations. The pooled proportion or odds ratio (OR) and 95% CI confidence interval (CI) were calculated for each analysis to explore the prevalence of asymptomatic infection and coinfection, as well as to assess the sex of SARS-CoV-2-infected children. RESULTS: We obtained data from 14 eligible studies with 410 patients for the meta-analysis. The pooled proportion of asymptomatic infection was 40.45% (95% CI, 24.04-56.85), while coinfection was 10.14% (95% CI, 3.97-16.30), of which Mycoplasma pneumonia (50%; 95% CI, 28.24-71.76) and influenza virus or parainfluenza virus (22.76%; 95% CI, 4.76-40.77) were the most common pathogens. Both male and female children were susceptible to SARS-CoV2 infection. And the pooled proportion of family clustering infection was 83.63% (95% CI, 77.54-89.72). CONCLUSION: A high proportion of asymptomatic infections occurs in children infected with SARS-CoV2, who are also susceptible to coinfection regardless of sex. These data affirm the increasing public health burden arising from infected children regarding the causation of asymptomatic infection or misdiagnosis and as a significant contributor to virus spread. The public should pay more attention to children during epidemics and conduct multimethod detection to further effectively identify infected children and control the source of infection.

Host microRNAs and exosomes that modulate influenza virus infection.

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate over half of human protein-coding genes and play a vital role in cellular development, proliferation, metabolism, and homeostasis. Exosomes are rounded or cup-like extracellular vesicles that carry proteins, mRNAs, miRNAs, and lipids for release and exchange messages between cells involved in various cellular processes. Influenza virus is a substantial public health challenge. The expression of host miRNAs is altered in response to stimulation by influenza virus. These dysregulated miRNAs directly or indirectly target viral genes to regulate viral replication and stimulate or suppress innate immune responses and cell apoptosis during viral infection. Exosomes released by infected cells are associated with the transfer of antigens and key molecules that activate and modulate immune function. Dysregulation of miRNAs and secretion of exosomes are associated with pathogenicity and immune regulation during influenza infection. This review provides a comprehensive summary of the information available regarding host miRNAs and exosomes that are involved in the modulation of influenza virus infection and will facilitate the development of preventative or therapeutic strategies against influenza virus.
