Authors: Zheng Linfu , Li Dazhou , Wang Wen 
Published: November 2020

Abstract
Background
Ectopic spleen is extremely rare. Most cases are congenital, acquired ectopic spleen may be a consequence of surgery or trauma to the spleen. The ectopic spleen in the gastric wall we reported is even rarer.

Case presentation
We report a 41-year-old female patient, with a past history of splenectomy, who presented with heartburn. Gastroscopy revealed a swelling in the fundus in the stomach. Ultrasonography and computed tomographic examination suggested the possibility of gastrointestinal stromal tumor. We performed endoscopic resection of the mass. Pathological examination of the resected mass showed ectopic spleen.

Conclusion
When a patient with a history of splenectomy presents with a gastric submucosal tumor, ectopic spleen should also be considered in the differential diagnoses. And minimally invasive endoscopic treatment can achieve the purpose of diagnosis and treatment for unobvious submucosal tumors.

AbstractBackgroundMaternal undernutrition is highly prevalent in underdeveloped countries. Hence, this study was intended to determine the prevalence and associated factors of undernutrition among pregnant women visiting ANC clinics in Silte Zone.MethodFacility-basedcross-sectional study was conducted from July to January 2019. Systematic random sampling technique was used to select 422 study participants from 11 randomly selected health facilities. Data was collected by using a structured-interviewer administered questionnaire. Mid upper arm circumference (MUAC) was measured by standard non stretchable MUAC tape. Data was entered into a computer using Epi data 3.1 and edited, cleaned, and analyzed using SPSS version 20. Both bivariate and multiple logistic regression analyses were employed to identify factors associated with maternal undernutrition.ResultIn this study, the overall prevalence of undernutrition among study subjects was 21.8%. Age greater than 31 years of women (AOR = 0.15; 95% CI: 0.03, 0.93), Birth intervals > 2 years (AOR = 0.18; 95% CI: 0.04, 0.76), good nutritional knowledge (AOR = 0.34; 95% CI: 0.17, 0.67), and having no dietary change as a result of current pregnancy AOR = 6.02; 95% CI: 2.99, 12.14) were significantly associated with undernutrition.ConclusionsThe prevalence of undernutrition among pregnant women was 21.8%. Current estimate is lower than previously reported in the study area but higher than reported in developed country. Age of women, Birth intervals, and Dietary change as a result of current pregnancy and Nutrition knowledge were important risk factors/ predictors of undernutrition (MUAC < 23 cm). Interventions targeting maternal nutrition education and child spacing with giving special emphasis to adolescent pregnant women are recommended.

AbstractBackgroundJoint hemorrhage is caused by trauma, ligament reconstruction surgery, and bleeding disorders such as hemophilia. Recurrence of hemorrhage in the joint space induces hemosiderotic synovitis and oxidative stress, resulting in both articular cartilage degeneration and arthropathy. Joint immobilization is a common treatment option for articular fractures accompanied by joint hemorrhage. Although joint hemorrhage has negative effects on the articular cartilage, there is no consensus on whether a reduction in joint hemorrhage would effectively prevent articular cartilage degeneration. The purpose of this study was to investigate the effect of joint hemorrhage combined with joint immobilization on articular cartilage degeneration in a rat immobilized knee model.MethodsThe knee joints of adult male rats were immobilized at the flexion using an internal fixator from 3 days to 8 weeks. The rats were randomly divided into the following groups: immobilized blood injection (Im-B) and immobilized-normal saline injection (Im-NS) groups. The cartilage was evaluated in two areas (contact and non-contact areas). The cartilage was used to assess chondrocyte count, Modified Mankin score, and cartilage thickness. The total RNA was extracted from the cartilage in both areas, and the expression of metalloproteinase (MMP)-8,MMP-13, interleukin (IL)-1β, and tumor necrosis factor (TNF)-α was measured by quantitative real-time polymerase chain reaction.ResultsThe number of chondrocytes in the Im-B group significantly decreased in both areas, compared with that in the Im-NS group. Modified Mankin score from 4 to 8 weeks of the Im-B group was significantly higher than that of the Im-NS group only in the contact area. The expression ofMMP-8andMMP-13from 2 to 4 weeks andTNF-αfrom 2 to 8 weeks significantly increased in the Im-B group compared with those in the Im-NS group, but there was no significant difference inIL-1βexpression.ConclusionsThe results showed that joint hemorrhage exacerbated immobilization-induced articular cartilage degeneration. Drainage of a joint hemorrhage or avoidance of loading may help prevent cartilage degeneration during joint immobilization with a hemorrhage.

Abstract
Background
The purpose of this study was to clarify the reliability and validity of pelvic floor muscle (PFM) strength assessment using the MizCure perineometer in healthy women.

Methods
Twenty healthy women (age 20–45 years) participated in this study. The vaginal pressure measured using the MizCure and validated Peritron perineometers were repeated during PFM contraction in the supine and standing positions. All women were evaluated twice by examiners 1 and 2. Following the measurements in the first session (Test 1), they were repeated after an interval of between 2 and 6 weeks (Test 2). Within- and between-session intra- and inter-rater reliabilities in vaginal pressure were analyzed using intraclass correlation coefficients (ICC) (1, 1) and (2, 1), respectively. Validity was assessed by Pearson’s product-moment correlation coefficient and Spearman’s rank correlation analysis.

Results
Within-session intra-rater reliabilities for both examiners 1 and 2 for all vaginal pressures in Tests 1 and 2 were 0.90–0.96 for both perineometers. Between-session intra-rater reliability for the MizCure was 0.72–0.79 for both positions for examiner 1, and 0.63 in the supine position and 0.80 in the standing position for examiner 2. Inter-rater reliability for Test 1 was 0.91 in the supine position and 0.87 in the standing position for the MizCure. The vaginal pressures using the MizCure and Peritron were significantly associated with the supine position (r = 0.68, P < .001) and the standing position (rs = 0.82, P < .001).

Conclusion
MizCure perineometer is a validated tool to measure PFM strength in both supine and standing positions in healthy nulliparous women.
Intensive and pharmacological care in times of COVID-19: A “special ethics” for emergency?
Authors: Marinelli Enrico , Busardò Francesco Paolo , Zaami Simona 
Published: November 2020

AbstractBackgroundThe Authors have laid out an analysis of Italian COVID-19 confirmed data and fatality rates, pointing out how a dearth of health care resources in northern regions has resulted in hard, ethically challenging decisions in terms of granting patient access to intensive care units (ICU).Main textHaving to make such decisions certainly entails substantial difficulties, and that has led many health care professional to seek ethical guidance. The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) has attempted to meet that growing need by a set of recommendations, applying “clinical soundness” as a beacon standard; that approach tends to prioritize patients with higher life expectancy, which could be characterized as a “moderately utilitarian” approach. Yet, such a selection has engendered daunting ethical quandaries. The authors believe it can only be warranted and acceptable if rooted in a transparent decision-making process and verifiable, reviewed criteria. Moreover, the authors have stressed how clinical experimentation in a pandemic setting is a subtext of great interest from an ethical perspective. In Italy, no drug therapy and trials were undertaken for COVID-19 patients for a rather long period of time. When the epidemic was already circulating, an intervention proved necessary on the system of administrative procedures, aimed at expediting the authorization and validation of protocols, then bogged down by bureaucracy. A new system has since been instituted by a government decree that was signed about one month after the first Covid-19 case was officially recorded in the country. Such a swift implementation, which took just a few weeks, is noteworthy and proves that clinical trials can be initiated in a timely fashion, even with a pandemic unfolding. The concerted, action of supportive care and RCTs is the only way to attain effective forms of treatments for COVID-19 and any other future outbreak.ConclusionsThe authors have arrived at the conclusion that the most effective and ethically sound response on the part of any national health care system would be to adequately reconfigure its organizational mechanisms, by making clinical trials and all related administrative procedures consistent with the current state of emergency.

Abstract
Background
Interferon (IFN) regulatory factors (IRFs), as transcriptional regulatory factors, play important roles in regulating the expression of type I IFN and IFN- stimulated genes (ISGs) in innate immune responses. In addition, they participate in cell growth and development and regulate oncogenesis.

Results
In the present study, the cDNA sequence of IRF10 in common carp (Cyprinus carpio L.) was characterized (abbreviation, CcIRF10). The predicted protein sequence of CcIRF10 shared 52.7–89.2% identity with other teleost IRF10s and contained a DNA-binding domain (DBD), a nuclear localization signal (NLS) and an IRF-associated domain (IAD). Phylogenetic analysis showed that CcIRF10 had the closest relationship with IRF10 of Ctenopharyngodon idella. CcIRF10 transcripts were detectable in all examined tissues, with the highest expression in the gonad and the lowest expression in the head kidney. CcIRF10 expression was upregulated in the spleen, head kidney, foregut and hindgut upon polyinosinic:polycytidylic acid (poly I:C) and Aeromonas hydrophila stimulation and induced by poly I:C, lipopolysaccharide (LPS) and peptidoglycan (PGN) in peripheral blood leucocytes (PBLs) and head kidney leukocytes (HKLs) of C. carpio. In addition, overexpression of CcIRF10 was able to decrease the expression of the IFN and IFN-stimulated genes PKR and ISG15.

Conclusions
These results indicate that CcIRF10 participates in antiviral and antibacterial immunity and negatively regulates the IFN response, which provides new insights into the IFN system of C. carpio.

AbstractBackgroundTo establish and validate a multi-parametric prognostic model based on clinical features and serological markers to estimate the overall survival (OS) in non-small cell lung cancer (NSCLC) patients with chronic hepatitis B viral (HBV) infection.MethodsThe prognostic model was established by using Lasso regression analysis in the training cohort. The incremental predictive value of the model compared to traditional TNM staging and clinical treatment for individualized survival was evaluated by the concordance index (C-index), time-dependent ROC (tdROC) curve, and decision curve analysis (DCA). A prognostic model risk score based nomogram for OS was built by combining TNM staging and clinical treatment. Patients were divided into high-risk and low-risk subgroups according to the model risk score. The difference in survival between subgroups was analyzed using Kaplan–Meier survival analysis, and correlations between the prognostic model, TNM staging, and clinical treatment were analysed.ResultsThe C-index of the model for OS is 0.769 in the training cohorts and 0.676 in the validation cohorts, respectively, which is higher than that of TNM staging and clinical treatment. The tdROC curve and DCA show the model have good predictive accuracy and discriminatory power compare to the TNM staging and clinical treatment. The prognostic model risk score based nomogram show some net clinical benefit. According to the model risk score, patients are divided into low-risk and high-risk subgroups. The difference in OS rates is significant in the subgroups. Furthermore, the model show a positive correlation with TNM staging and clinical treatment.ConclusionsThe prognostic model showed good performance compared to traditional TNM staging and clinical treatment for estimating the OS in NSCLC (HBV+) patients.
Hsa_circ_0004831 serves as a blood-based prognostic biomarker for colorectal cancer and its potentially circRNA-miRNA-mRNA regulatory network construction
Authors: Xing Linlin , Xia Mengyan , Jiao Xin , Fan Ling 
Published: November 2020

AbstractBackgroundColorectal cancer (CRC) is a common malignant tumor with unsatisfactory overall prognosis. CircRNAs could be promising prognostic biomarkers in cancers, and play important role in the process of tumorigenesis and progression. Here, we explored the role of hsa_circ_0004831 in blood extracellular vesicles and its prognostic value in CRC.MethodsThe circRNA and mRNA expression level matrix in extracellular vesicles of CRC and normal samples were obtained from the exoRBase database. The corresponding miRNA expression level matrix in extracellular vesicles was downloaded from the BBCancer database. Differentially expressed circRNAs, miRNAs and mRNAs were identified using the limma package of R software at the cut-off criteria of fold change (FC) > 2 and adj. p < 0.05. RT-qPCR assay was conducted to measure hsa_circ_0004831 expression level in CRC blood samples. A circRNA-miRNA-mRNA regulatory network of hsa_circ_0004831 was constructed based on competitive endogenous RNA mechanism and differentially expressed genes. The mRNAs co-expressed with hsa_circ_0004831 were screened at the cut-off criteria of pearson |r| > 0.3 and p < 0.05. Gene set enrichment analysis (GSEA) based on co-expressed mRNAs was used to explore the potential molecular function of hsa_circ_0004831.ResultsDifferentially expressed circRNAs, miRNAs and mRNAs were identified and hsa_circ_0004831 had a FC value of 3.92 in CRC blood extracellular vesicles. The RT-qPCR assay showed that the hsa_circ_0004831 was up-regulated in CRC blood samples. The overall survival analysis found that high expression of hsa_circ_0004831 was linked with poorer prognosis. Finally, a circRNA-miRNA-mRNA regulatory network of hsa_circ_0004831 was constructed based on down-regulated miR-4326 and 12 up-regulated mRNAs. GSEA indicated that mRNAs co-expressed with hsa_circ_0004831 were involved in EMT, WNT and p53 signaling pathways.ConclusionsThe study confirmed the up-regulation of hsa_circ_0004831 in CRC, and it may act as a vital prognostic biomarker. The circRNA-miRNA-mRNA regulatory network of hsa_circ_0004831 could be used to uncover the tumorigenesis and progression of CRC.

Published: November 2020

AbstractBackgroundThe menace of resistance to anti-malarial drugs is a great challenge to malaria control, necessitating the search for new anti-malarial agents. This search has led to the exploration of natural products for efficacy in malaria therapy.Omidunis the supernatant of fermenting maize (ogi) slurry that has been widely investigated and reported to possess several health benefits and it is used traditionally as solvent for preparing anti-malarial herbs. However, there is no information on the anti-malarial activity ofomidunitself. This study was conducted to investigate the prophylactic, curative and suppressive anti-malarial potential ofomidun.MethodsExperimental mice in the curative group were infected with 1 × 106cells ofPlasmodium bergheistrain ANKA and treated with either 0.2 ml ofomiduncontaining 3 × 109 cfu/ml of viable lactic acid bacteria or 0.2 ml of 5 mg/kg of chloroquine (positive control) or 0.2 ml of saline (negative control) for 4 days from day 3 post infection. The prophylactic group of mice were pre-treated with eitheromidun, chloroquine or saline for 4 days before infection withP. berghei, while the suppressive group was treated withomidunor chloroquine or saline and infected withP. bergheisimultaneously. A group of mice were uninfected but treated (withomidunand control samples), while a final group was uninfected and untreated (controls). Parasitaemia and histopathology analysis were done in all groups.ResultsThe curative and suppressive groups showed a significant difference between theomidun-treated mice (100% parasitaemia reduction) and the untreated mice (54.5% parasitaemia increase). There was no significance difference between theomiduntreatment and chloroquine (positive control) treatment in suppressive group as both treatment had 100% parasitaemia reduction. Theomidunprophylactic treatment however did not show any parasitaemia suppression, but a significant difference was observed between theomiduntreatment (85% increase) and the chloroquine (positive control) treatment (100% reduction) in the group.Omiduntreatment is non-toxic to the kidney.ConclusionThis study provides scientific evidence supportingomidunusage in the treatment of malaria. Consequently, further work may yield the specific component ofomidunresponsible for the anti-malarial activity.

Published: November 2020

AbstractThe world is now experiencing its third major epidemic of coronavirus (CoV) infections began in Wuhan, Hubei, China, in late 2019 and named COVID-19. After an initial explosive outbreak of pneumonia of unknown etiology in China, the disease spread first to neighboring Asian countries and then worldwide. Patients with COVID-19 presented with a constellation of symptoms such as fever, dry cough, dyspnea, sore throat, and nasal congestion and radiological findings showed bilateral lung glassy opacities. Vitamin D has many mechanisms by which it reduces the risk of microbial infection and death, including physical barrier, cellular natural immunity, and adaptive immunity. Vitamin D supplementation has shown favorable effects in viral infections including influenza and HIV. The effects of vitamin D supplementation during covid 19 infection remain controversial. Looking ahead, clinical studies are needed to define better cut offs for vitamin D levels and, finally, which dosage is the best.

Abstract
Background
Analysis of the risk factors associated with functional delayed gastric emptying after distal gastric cancer surgery to provide a basis for further reduction of the incidence of this complication.

Methods
Total of 1382 patients with distal gastric cancer from January 2016 to October 2018 were enrolled. Correlation analysis was performed in 53 patients with FDGE by logistic regression. Subgroup risk analysis was performed in 114 patients with preoperative pyloric obstruction. A Pearson Chi-square analysis was used to compare categorical variables between normal distribution groups. Meanwhile, a t test was used to compare continuous variables between groups. Odds ratio (OR) was used for comparison of the two groups, and it was summarized with its 95% confidence interval (CI) and p value using logistic regression.

Result
In multivariable analysis, age (OR 1.081, 95% CI, 1.047–1.117), BMI (OR 1.233, 95% CI, 1.116–1.363), preoperative pyloric obstruction (OR 3.831, 95% CI, 1.829–8.023), smaller volume of residual stomach (OR 1.838, 95% CI, 1.325–6.080), and anastomosis in greater curvature perpendicular (OR 3.385, 95% CI, 1.632–7.019) and in greater curvature parallel (OR 2.375, 95% CI, 0.963–5.861) were independent risk factors of FDGE. In the preoperative pyloric obstruction group, higher BMI (OR 1.309, 95% CI, 1.086–1.579) and preoperative obstruction time (OR 1.054, 95% CI, 1.003–1.108) were independent risk factors of FDGE and preoperative gastrointestinal decompression (OR 0.231, 95% CI, 0.068–0.785) was independent protective factor of FDGE.

Conclusion
Adequate gastrointestinal decompression should be performed before the operation to reduce the incidence of postoperative gastroparesis in patients with preoperative pyloric obstruction. We also could improve the surgical methods to reduce the occurrence of FDGE, such as controlling the size of the residual stomach, ensuring blood supply. Especially selecting an appropriate stapler and anastomosis during the anastomosis process, the occurrence of FDGE can be reduced.
