ABSTRACT

Objective:To explore the relationship between endotracheal tube-bacterial biofilm (ETT-BF) in mechanically ventilated neonates and ventilator-associated pneumonia (VAP).Methods:A total of 30 mechanically ventilated neonates whose mechanical ventilation time were ≥48 h in the Department of Neonatology in The Second Affiliated Hospital of Wenzhou Medical University from January 2019 to January 2020 were included.According to the indwelling time of endotracheal tube, all cases were divided into three groups including group A(two to six days), group B(seven to 14 days) and group C (over 14 days). The morphological results of ETT-BF were scanned by scanning electron microscope (SEM). The incidence of VAP, the positive rates of strains isolated from endotracheal tube surface and lower respiratory tract secretion, the detection of strains and drug resistance were analyzed. Chi-squared test were used for statistical analysis.Results:The results of SEM showed that sheet matrix could be observed on the surface of the inner cavity of endotracheal tube in three days of tracheal catheter retention, and cocci adhered to it in four days. With prolonged indwelling time of endotracheal tube, the structure of bacterial biofilm (BF) had improved.The positive rate of strains isolated from the secretion of lower respiratory tract in 30 neonates was 23.3%(7/30) and all of them were Gram-negative bacteria. There was no patient developed VAP in group A, while there were two patients with VAP in group B, and five patients with VAP in group C. The incidences of VAP in the three groups were statistically significant ( χ2=10.82, P=0.004). There was no significant difference in the positive rate of strains isolated from the surface of endotracheal tube under different indwelling time in 30 cases ( χ2=1.03, P=0.598). Among of 13 neonates in group A, there were seven strains isolated from ETT-BF, mainly Gram-positive bacteria which turned out to be mainly Gram-negative bacteria with the prolongation of endotracheal tube indwelling time. Of the seven VAP cases, strains isolated from the lower respiratory tract secretion were consistent with the strains isolated from the surface of the corresponding endotracheal tube in five cases, which were Serratia liquefaciens, Klebsiella acidogenes, Serratia marcescens, Flavobacterium meningosepticum and Stenotrophomonas maltophilia, and the drug resistance was consistent. Conclusions:The colonization bacteria of early ETT-BF may come from the upper respiratory tract, with less migration which rarely causes VAP. With the prolongation of endotracheal tube indwelling time, the incidence of VAP in neonates increases. The same pathogen can be found in the ETT-BF and lower respiratory tract secretion. The source of pathogen needs further study.

ABSTRACT

Objective: To explore the dynamic changes of vestibular autorotation test (VAT) before and after vestibular rehabilitation treatment in patients with unilateral vestibular hypofunction (UVH). Methods: A retrospective study was carried out,48 patients who were diagnosed with UVH and under vestibular rehabilitation in department of otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2019 to January 2021 were enrolled. Among them, there were 21 males and 27 females, with an average age of 46.9 years old, including 25 cases of Meniere's disease, 13 cases of sudden deafness with vertigo and 10 cases of vestibular neuritis. The course of disease ranged from 5 days to 10 years. Demographic characteristics, detailed case data and routine examination were collected for the patients. The horizontal gain/phase, vertical gain/phase, and asymmetry of VAT at different frequencies before and after vestibular rehabilitation were collected. The absolute value of the difference between the measured value of 2.0-5.9 Hz before and after rehabilitation and the standard value were statistically analyzed. Results: Before vestibular rehabilitation, the incidence of abnormal gain was 62.5% (30/48), the incidence of abnormal phase was 56.3% (27/48), and the incidence of asymmetry was 16.7% (8/48). After 4-6 weeks of vestibular rehabilitation, the incidence of gain abnormality was 22.9% (11/48), the incidence of phase abnormality was 31.3% (15/48), and the incidence of asymmetry was 12.5% (6/48).The horizontal gain at frequency of 2.0-3.9 Hz showed statistically significant difference compared with before vestibular rehabilitation (P<0.05), and the horizontal gain at frequency of 4.3-5.9 Hz showed that there was no significant difference (P>0.05); the horizontal phase at 5.9 Hz showed that the difference was statistically significant (P=0.043), and there was no significant difference before and after rehabilitation treatment at 2.0-5.5 Hz (P>0.05); the vertical gain at 4.3 Hz showed the difference was statistically significant (P=0.020), and the remaining frequency showed no significant difference (P>0.05); No frequency of asymmetry and vertical phase showed the difference before and after rehabilitation was statistically significant (P>0.05). Conclusion: VAT can be used to monitor the change trend of multiple frequency bands before and after vestibular rehabilitation in UVH, in order to provide reference for the formulation of personalized rehabilitation strategies.

ABSTRACT

Purpose@#This study identified factors predicting malignant upgrade for atypical ductal hyperplasia (ADH) diagnosed on core-needle biopsy (CNB) and developed a nomogram to facilitate evidence-based decision making. @*Methods@#This retrospective analysis included women diagnosed with ADH at the National Cancer Centre Singapore (NCCS) in 2010–2015. Cox proportional hazards regression was used to identify clinical, radiological, and histological factors associated with malignant upgrade. A nomogram was constructed using variables with the strongest associations in multivariate analysis. Multivariable logistic regression coefficients were used to estimate the predicted probability of upgrade for each factor combination. @*Results@#Between 2010 and 2015, 238,122 women underwent mammographic screening under the National Breast Cancer Screening Program. Among 29,564 women recalled, 5,971 CNBs were performed. Of these, 2,876 underwent CNBs at NCCS, with 88 patients (90 lesions) diagnosed with ADH and 26 lesions upgraded to breast malignancy on excision biopsy. In univariate analysis, factors associated with malignant upgrade were the presence of a mass on ultrasound (p = 0.018) or mammography (p = 0.026), microcalcifications (p = 0.047), diffuse microcalcification distribution (p = 0.034), mammographic parenchymal density (p = 0.008). and ≥ 3 separate ADH foci found on biopsy (p = 0.024). Mammographic parenchymal density (hazard ratio [HR], 0.04; 95% confidence interval [CI], 0.005–0.35; p = 0.014), presence of a mass on ultrasound (HR, 10.50; 95% CI, 9.21–25.2; p = 0.010), and number of ADH foci (HR, 1.877; 95% CI, 1.831–1.920; p = 0.002) remained significant in multivariate analysis and were included in the nomogram. @*Conclusion@#Our model provided good discrimination of breast cancer risk prediction (C-statistic of 0.81; 95% CI, 0.74–0.88) and selected for a subset of women at low risk (2.1%) of malignant upgrade, who may avoid surgical excision following a CNB diagnosis of ADH.

ABSTRACT

Cardiovascular disease (CVD) is the leading cause of death worldwide. The top ten causes of death in Singapore include many cardiovascular-related diseases such as ischaemic heart disease. The increasing prevalence of CVD poses a burden to both the economy and healthcare system of a country. Dietary habits, in particular dietary fats and cholesterol intake, have been shown to greatly influence CVD risks. Therefore, reference and adherence to relevant dietary guidelines could be crucial in CVD prevention. Recent research findings have provided novel insights into the relationship between certain dietary fats or cholesterol intake and CVD risks, challenging or reinforcing previous guidelines. These findings may, however, be conflicting, and there are still controversies over the effects of dietary fats and cholesterol as well as their association with cardiovascular risk. This review paper aims to evaluate common controversies, identify gaps in relevant research areas and summarise evidence-based dietary recommendations.

ABSTRACT

A case of Gilbert syndrome (GS) with a heterozygous mutation in the gene is reported. The patient had no symptoms except for recurrent sclera icterus since childhood. Laboratory examinations revealed an elevated unconjugated bilirubin. Biliary obstruction, hemolysis and other diseases that might cause jaundice were excluded. *28 and c.211G>A heterozygous mutations in gene were found, which may be another type of mutation causing GS in Chinese population.

ABSTRACT

Objective@#To investigate the correlation between interleukin-6 (IL-6) single nucleotide polymorphism (SNP) and the occurrence and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF).@*Methods@#Patients with chronic hepatic diseases diagnosed as HBV infection in the Hepatology Center of the First Affiliated Hospital of Fujian Medical University from July 2012 to March 2018 were divided into HBV-ACLF and non-ACLF group. SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) was determined by the improved multi-temperature ligase detection reaction (imLDRTM) technique. Simultaneously, case data were reviewed with the 3-months followed up survival condition of the ACLF group. Normally distributed data were expressed as arithmetic means and SDs, and t-test was adopted. Data with skewed distribution were expressed as medians with interquartile range, and were measured by non-parametric test. Multivariate logistic regression analysis was used to analyze the relative risk of genetic polymorphism and HBV-ACLF as well as the relationship between IL-6 SNPs with the occurrence and prognosis of HBV-ACLF.@*Results@#Four hundred patients were included in the study, with 122 (30.5%) in the HBV-ACLF and 278 (69.5%) in the non-ACLF group. There were significant differences in total bilirubin, albumin, and white blood cell count, percentage of neutrophils, platelet count, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international standardized ratio, creatinine and the model for end-stage liver disease score between the two groups (P < 0.001). The genotype of IL-6 genes (rs1800795, rs1800797, rs2069827, and rs2069830) of all subjects showed no mutation or the mutation rate under 1%. There was no significant difference in the genotype of IL-6 (rs1524107, rs2069837, rs2069840 and rs2069845) between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the SNPs in the above four loci of IL-6 gene was not associated with HBV-ACLF risk, nor had significant correlation with the 3-months prognosis.@*Conclusion@#The SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) is unrelated to the occurrence and short-term prognosis of HBV-ACLF.

ABSTRACT

@# Introduction: The accurate measurement of the height of bedridden patients is difficult. Height assessment is required for the calculation of body mass index, which is crucial for determining the nutrition status of a patient. This study aimed to validate recumbent length measurement against the standing height measurement using soft and firm mattresses and to derive predictive equations to calculate the actual height of bedridden patients on mattresses with different firmness. Methods: Ninety-nine hospitalised participants (mean age 48.9±13.9 years; range 21–80 years) (49 men, 50 women) and 100 healthy participants (mean age 36.8±13.6 years; range 21–77 years) (50 men, 50 women) were recruited. Standing height was measured using a stadiometer. Recumbent length was measured using a 2 metre long measuring tape. Hospitalised participants lay on soft mattress and healthy participants on firm mattress. Results: Using Bland–Altman plot, 96% of hospitalised participants using soft mattress were within 2.5±2.7 cm (mean±2SD) whereas 97% of healthy participants using firm mattress were within 2.1±2.1 cm. The regression equation developed using firm mattress was Standing height (cm) = 0.993 x Recumbent length – 0.943; (r2=0.982). The regression equation developed using soft mattress was Standing height (cm) = 1.012 x Recumbent length – 4.477; (r2=0.981). Conclusion: We concluded that recumbent length is a valid clinical tool to estimate standing height. Standing height can be estimated from the predictive equations developed for patients lying on soft or firm mattresses.

ABSTRACT

Objective To investigate the association between interleukin-22 (IL-22) single nucleotide polymorphisms (SNPs) and the prognosis of hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF).Methods The patients with HBV-ACLF from the First Affiliated Hospital of Fujian Medical University were retrospectively studied.Seven SNP genotypes of IL-22 gene,including rs2227478,rs2227491,rs1179251,rs1179249,rs2227473,rs2227484,and rs11611206,were detected using imLDRTM multiple SNP typing kit and the distribution features of SNP genotypes were described.The relationship between the distribution of SNP genotypes and alleles and the prognosis of ACLF was analyzed.Comparison of genotypes and allele frequencies between groups were performed by chi-square test of R × C table or Fisher's exact tests.Binary logistic regression analysis was used to analyze whether IL-22 gene polymorphisms was an independent prognostic factor for patients with ACLF.Results A total of 122 patients with HBV-ACLF were included in this study.Ninety-two (75.1%) were male and 30 (24.59 %) were female.Patients were stratified as survival group (90 cases) and non-survival group (32cases) according to the Results of three months follow-up.The genotype distribution of rs2227484 of IL-22 gene was significantly different between the two groups (x2=6.128,P=0.033).The A allele frequency in the non-survival group (15.6%) was significantly higher than that in the survival group (5.6%) with statistically significance (OR=0.318,95% CI=0.126-0.804,P=0.012).There was no significant difference in the other six SNP genotypes of IL-22 gene between the two groups (all P>0.05).However,binary logistic regression showed that rs2227484 of IL-22 gene was not an independent risk factor for the short-term mortality in HBV-ACLF patients (adjusted OR=3.102,95% CI:0.939-10.250,P=0.063).Conclusions The A allele and AA genotype of rs2227484 of IL-22 gene may be associated with a short-term prognosis in patients with HBV-ACLF.

ABSTRACT

ObjectiveTo investigate the cost-effectiveness ratio of Gd-EOB-DTPA contrast-enhanced magnetic resonance imaging (EMRI) versus ultrasound in liver cancer screening for the high-risk population. MethodsThe TreeAge Pro 2011 software was used to establish a decision-tree model. A mathematical model was used to simulate the costs and benefits of EMRI or ultrasound screening every 6 months in patients with liver cirrhosis, and the cost-effectiveness ratios under different screening models were calculated. ResultsThe EMRI group had a mean cost of liver cancer screening of 2050.2 RMB each person each time and mean benefits of 0.11 YLG, while the ultrasound group had a mean cost of 262.6 RMB and mean benefits of 0.02 YLG. When the incidence rate of liver cancer was 17.8%, the EMRI group had a similar cost-effectiveness ratio as the ultrasound group, and the cost of 1 YLG was 11445 RMB; EMRI tended to have a lower cost and a better effect in screening with the increase in the incidence rate of liver cancer. The cost-effectiveness ratio of EMRI gradually decreased with the reduction in its price, and its effect in screening gradually increased with the reduction in price. ConclusionThe cost-effectiveness of liver cancer screening is closely related to the incidence rate of liver cancer and the price of screening. EMRI has a good cost-effectiveness ratio in screening when the risk of liver cancer is higher than 17.8%.

ABSTRACT

Radiofrequency ablation (RFA) is one of the most important methods for the treatment of liver cancer and has the advantages of small trauma,simple operation,and repeatability.However,for tumors in high-risk locations within 5 mm of the first and second branches of the hepatic portal vein,near the hepatic vein,the inferior vena cava,or the gallbladder,within 5 mm of the intestinal tract,under the Glisson's capsule,and in the diaphragm,RFA has the issues of a low complete ablation rate,a high local recurrence rate,and serious complications.This article introduces the complications of RFA for liver cancer in high-risk locations and their prevention and points out that with the promotion of individualized and standardized RFA,liver cancer in these high-risk locations is no longer a contradiction for RFA.

ABSTRACT

This study investigated the relationship among the severity of hearing impairment,vestibular function and balance function in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).A total of 35 ISSNHL patients (including 21 patients with vertigo) were enrolled.All of the patients underwent audiometry,sensory organization test (SOT),caloric test,cervical vestibular-evoked myogenic potential (cVEMP) test and ocular vestibular-evoked myogenic potential (oVEMP) test.Significant relationship was found between vertigo and hearing loss grade (P=0.009),and between SOT VEST grade and hearing loss grade (P=0.001).The abnormal rate of oVEMP test was the highest,followed by the abnormal rates of caloric and cVEMP tests,not only in patients with vertigo but also in those without vertigo.The vestibular end organs were more susceptible to damage in patients with vertigo (compared with patients without vertigo).Significant relationship was found between presence of vertigo and SOT VEST grade (P=0.010).We demonstrated that vestibular end organs may be impaired not only in patients with vertigo but also in patients without vertigo.The cochlear and vestibular impairment could be more serious in patients with vertigo than in those without vertigo.Vertigo does not necessarily bear a causal relationship with the impairment of the vestibular end organs.SOT VEST grade could be used to reflect the presence of vertigo state in the ISSNHL patients.Apart from audiometry,the function of peripheral vestibular end organs and balance function should be evaluated to comprehensively understand ISSNHL.Better assessment of the condition will help us in clinical diagnosis,treatment and prognosis evaluation of ISSNHL.

ABSTRACT

Objective: To identify and analyze the 50 most-cited gastroenterology and hepatology articles originating from mainland China


Methods: We utilized the 2015 edition of Journal Citation Reports and PubMed to determine the 50 most-cited gastroenterology and hepatology articles from 75 professional journals and four leading journals in clinical medicine, which are The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, and The British Medical Journal. Then we excluded the articles written outside mainland China and collected the basic information, including the title, authors, year of publication, source journal, city, institution, number of citations, and topic of the research


Results: The number of citations for the top 50 papers ranged from 279 to 89 [mean, 129]. These articles were published between 2005 and 2012, in which 2009 was the year with the largest number of highly cited papers [13]. All articles were published in 15 journals. The journal Hepatology published the largest number of articles [21], followed by Journal of Gastroenterology and Hepatology [4], Journal of Hepatology [4] and World Journal of Gastroenterology [4]. The top 50 articles originated mainly from Shanghai [20], Guangzhou [13] and Beijing [6]. Sun Yat-sen University produced most highly cited papers [10]. The number of basic research was far more than clinical research, of which the ratio was about 1.78[32:18]. In all these articles, hepatocellular carcinoma was the most-discussed topic [19], followed by hepatitis B virus [8] and endoscopic [5]


Conclusions: Although a large gap remains between mainland China and the global community, the gastroenterology and hepatology research from China is gradually recognized by the world

ABSTRACT

Objective To investigate the correlation between non-alcoholic fatty liver disease and serum and histological viral parameters in patients with chronic hepatitis B (CHB).Methods Clinical and laboratory data from patients with CHB who received liver biopsy from 2009 to 2015 were collected. Patients were divided into steatosis and non-steatosis groups based on the presence of steatosis in liver biopsies.Propensity score matching (PSM)was conducted to adjust the confounding bias including age, sex,body mass index (BMI),total cholesterol (TC)and triglyceride (TG).Correlation of liver fatty and viral parameters was compared between steatosis and non-steatosis groups.Student t test,χ2 test,rank sum test and Pearson correlation test were employed to analyze the data.Results A total of 874 patients with a mean age of (37.0±10.1)years were enrolled in the study,with 690 males and 184 females,and 270 (30.9%)patients were diagnosed with steatosis by liver biopsy.Age,gender,BMI,TC and TG were significantly different between the two groups before PSM (all P 0.05 ).Serum hepatitis B virus (HBV)DNA,hepatitis B surface antigen (HBsAg) level,proportion of hepatitis B e antigen (HBeAg )positivity,HBsAg and hepatitis B core antigen (HBcAg)immunohistological staining in liver tissue were not significantly different between steatosis and non-steatosis groups after PSM (all P >0.05).Patients in steatosis group were stratified into two groups according to the degree of steatosis confirmed by liver biopsies:mild steatosis group (F1 )and medium to severe steatosis group (F2-F4).The serum alanine aminotransferase (ALT),HBV DNA,HBsAg level, proportion of HBeAg positivity,immunohistological HBsAg and HBcAg staining in liver tissue between those two groups showed no differences (all P >0.05).The mean rank of liver inflammation and fibrosis in F1 group were 129.9 and 128.2,respectively,which were both significantly higher than those in F2-F4 group (105 .9 and 108.5 ,respectively;both P <0.05).Steatosis was negatively correlated with either inflammatory grade (r=-0.183,P =0.005)or fibrosis stage (r=-0.150,P =0.020).Conclusions There is no correlation between serum viral factors and hepatic steatosis. Hepatic steatosis is not associated with the expressions of HBsAg and HBcAg in liver tissue.The severity of steatosis is negatively correlated with both liver inflammation and fibrosis.

ABSTRACT

Echogenic breast lesions are generally thought to be benign. We herein report four cases of echogenic breast lesions that were seen at our centre over 38 months. One patient had a prior history of wide excision and radiotherapy for breast cancer and was imaged as part of routine cancer surveillance, while the other three were recalled for further assessment following an abnormal screening mammogram. All four patients were assessed on ultrasonography, which demonstrated an echogenic lesion in each patient. All four lesions underwent ultrasonography-guided core biopsy, followed by excision biopsy. The indications for biopsy were interval increase in the size of lesion or indeterminate features demonstrated in the lesion. Three lesions were benign, while the lesion from the patient who had received previous radiotherapy was angiosarcoma. Not all echogenic lesions are benign and lesions with suspicious features on ultrasonography should undergo biopsy.

ABSTRACT

Objective The aim of this prospective observational study was to analyze the prevalence and the predictive factors of hemorrhagic events after abdominal paracentesis in patients with acute-on-chronic liver failure (ACLF).Methods ACLF patients who received at least one episode of abdominal paracentesis were prospectively enrolled between January 2010 to December 2013. Prevalences of intraperitoneal and abdomen hemorrhage complications were examined. t test was performed for continuous variables and chi-square test was performed for categorical variables.Binary Logistic regression was used to analyze the risk factors of hemorrhage.Results A total of 525 abdominal paracenteses were carried out on 185 ACLF patients within a 4-year period,with 289 (55 .0%)for diagnostic purpose and 236 (45 .0%)for therapeutic purpose.A total of 16 (3.0%)hemorrhagic complications were identified, with 4 cases of abdominal wall hematomas and 12 cases of intraperitoneal hemorrhage.Patients were divided into hemorrhage group and non-hemorrhage group according to this complication.Age,gender, Child-Pugh score,volume of ascitic fluid removed,underlying cirrhosis,platelet count and thrombin time were not significantly different between two groups (all P > 0.05 ).Patients with bleeding events had lower fibrinogen levels and higher prothrombin time,international normalized ratio,activated partial thromboplastin time and model for end-stage liver disease score (all P <0.05).After adjustment of other factors,multivariate regression analysis indicated that low fibrinogen level was the only independent predictor of hemorrhagic complication (OR=0.105,95%CI :0.018-0.608,P =0.012).Conclusion Low fibrinogen level is the independent predictor of severe hemorrhagic complications following paracenteses in patients with ACLF.

ABSTRACT

This study looked into the efficacy of a modified titration protocol of intratympanic gentamicin injection (ITG) in the patients with unilateral intractable Ménière's disease (MD). Modified titration protocol of ITG at a low dose (20 mg/mL) was administered to 10 patients with definite unilateral intractable MD. After initial first two fixed ITGs on weekly basis, the patients might or might not be given any more injections, depending on the appearance of unilateral vestibular loss (UVL). ITG was terminated if the patients satisfied the criteria of UVL. All patients were followed-up for at least two years. The effects of ITG on the vertigo attack, functional level scores and postural balance were evaluated. Of the 10 cases, 8 showed the sign of UVL after receiving initial two ITGs and were not given any more intratympanic injections, and the other 2 patients were administered three ITGs. A two-year follow-up revealed that complete and substantial vertigo control was achieved in 9 cases, and limited vertigo control in 1 patient. Hearing level was lowered in 2 patients. The posture stability and functional level scores were improved. Our study showed that the modified titration protocol of ITG at a low dose could effectively control vertigo in patients with unilateral intractable MD.

ABSTRACT

Thirty one Vibrio cholera isolates recovered from cholera outbreak in Bintulu, Sarawak (Malaysia) were detected with the presence of ctx gene by using specific PCR. These isolates were further characterized and differentiated by using the Enterobacterial Repetitive Intergenic Consensus PCR (ERIC-PCR) and BOX-PCR to determine their genomic fingerprints. The specific PCR result confirmed the identities of 27 isolates out of 31 as pathogenic V. cholerae. The ERIC-PCR generated several genetic profiles consisting of 4-6 bands with sizes in the range of 100 to 600 bp, while the BOX-PCR produced profiles numbering 2-7 bands in the sizes between 200 to 1000 bp. Based on the dendrogram generated from the DNA fingerprinting profiles (ERIC-PCR and BOX-PCR), all of the isolates can be divided into 2 main clusters that is further divided into 2 sub-clusters. The low genetic diversity of the isolates indicated the outbreak of V. cholerae in the study area was due to the contamination from a single or few sources of V. cholerae.
