Clinical manifestations and early effectiveness of methimazole in patients with graves' hyperthyroidism-related severe hepatic dysfunction.

BACKGROUND: Graves' hyperthyroidism (GH) is often accompanied by mild to moderate liver injury, but severe hepatic dysfunction (SHD) is relatively rare. Whether patients with GH-related SHD can be treated with methimazole (MMI) remains controversial. This study aimed to determine the clinical characteristics and to evaluate the role of low-dose MMI for such patients. METHODS: 33 patients with GH-related SHD were selected for this retrospective study in the Fifth Medical Center of Chinese PLA General Hospital from January 2017 to July 2022. The clinical manifestations, therapeutic responses, and effectiveness of MMI were evaluated. RESULTS: Systemic jaundice (100.0%), yellow urine (100.0%), fatigue (87.9%), and goiter (66.7%) were the main symptoms. Total bilirubin (TBIL) had no linear correlation with free triiodothyronine (FT3) (r = -0.023, p = .899), free thyroxine (FT4) (r = 0.111, p = .540), T3 (r = -0.144, p = .425), and T4 (r = 0.037, p = .837). On the 14th day after admission, FT3, FT4, T3, T4, TBIL, direct bilirubin (DBIL), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), γ-glutamyltransferase (GGT), and international normalized ratio (INR) decreased compared with the baseline (p < .05). The decrease rates of FT3, FT4, T3, T4, TBIL, and DBIL in the MMI group were higher than those in the non-MMI group (p < .05). The improvement rate of the MMI group (77.8%) was higher than that of the non-MMI group (9.5%, p = .001). MMI treatment is an independent predictor affecting the early improvement of patients (OR = 0.022, p = .010). CONCLUSIONS: The main clinical manifestations of patients with GH-related SHD were symptoms related to liver disease. Low-dose MMI was safe and effective for them.

The diagnostic performance of ultrasound computer-aided diagnosis system for distinguishing breast masses: a prospective multicenter study.

OBJECTIVES: To evaluate the diagnostic value of computer-aided diagnosis (CAD) software on ultrasound in distinguishing benign and malignant breast masses and avoiding unnecessary biopsy. METHODS: This prospective, multicenter study included patients who were scheduled for pathological diagnosis of breast masses between April 2019 and November 2020. Ultrasound images, videos, CAD analysis, and BI-RADS were obtained. The AUC, accuracy, sensitivity, specificity, PPV, and NPV were calculated and compared with radiologists. RESULTS: Overall, 901 breast masses in 901 patients were enrolled in this study. The accuracy, sensitivity, specificity, PPV and NPV of CAD software were 89.6%, 94.2%, 87.0%, 80.4%, and 96.3, respectively, in the long-axis section; 89.0%, 91.4%, 87.7%, 80.8%, and 94.7%, respectively, in the short-axis section. With BI-RADS 4a as the cut-off value, CAD software has a higher AUC (0.906 vs 0.734 vs 0.696, all p < 0.001) than both experienced and less experienced radiologists. With BI-RADS 4b as the cut-off value, CAD software showed better AUC than less experienced radiologists (0.906 vs 0.874, p < 0.001), but not superior to experienced radiologists (0.906 vs 0.883, p = 0.057). After the application of CAD software, the unnecessary biopsy rate of BI-RADS categories 4 and 5 was significantly decreased (33.0% vs 11.9%, 37.8% vs 14.5%), and the malignant rate of biopsy in category 4a was significantly increased (11.6% vs 40.7%, 7.4% vs 34.9%, all p < 0.001). CONCLUSIONS: CAD software on ultrasound can be used as an effective auxiliary diagnostic tool for differential diagnosis of benign and malignant breast masses and reducing unnecessary biopsy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (NCT03887598) KEY POINTS: • Prospective multicenter study showed that computer-aided diagnosis software provides greater diagnostic confidence for differentiating benign and malignant breast masses. • Computer-aided diagnosis software can help radiologists reduce unnecessary biopsy. • The management of patients with breast masses becomes more appropriate.

[Mean microvessel density of the prepuce and its relationship with the severity of hypospadias and early postoperative complications].

OBJECTIVE: To investigate the mean preputial microvessel density (mMVD) and features of hypospadias and their relationship with the severity and early postoperative complications of the disease. METHODS: Sixty children with hypospadias and another 14 age-matching ones with phimosis (the control group) underwent penile curvature correction, Snodgrass procedure or staged surgery, the excessive dorsal foreskin trimmed and retained. We determined the mMVD in the prepuce tissue of the patients by immunohistochemistry, and followed up those treated by Snodgrass procedure. RESULTS: The mMVD was significantly lower in the patients with severe hypospadias than in those with mild hypospadias and the controls (15.51 ± 3.53 vs 19.27 ± 4.42 and 22.09 ± 6.15, P < 0.05), with a median of 21.8 in the control group. The incidence of postoperative complications was obviously lower in the high mMVD (≥ 21.8) than in the low mMVD (< 21.8) group. CONCLUSIONS: The preputial mMVD is significantly lower in patients with severe hypospadias than in normal children, decreasing in a severity-dependent manner. The lower the preputial mMVD, the higher the incidence rate of postoperative complications. The preputial mMVD of 21.8 can be used as a reference index for evaluating the prognosis of surgery clinically. ?

Added Value of a New Strain Elastography Technique in Conventional Ultrasound for the Diagnosis of Breast Masses: A Prospective Multicenter Study.

OBJECTIVE: This study aimed to explore the value of elasticity score (ES) and strain ratio (SR) combined with conventional ultrasound in distinguishing benign and malignant breast masses and reducing biopsy of BI-RADS (Breast Imaging Reporting and Data System) 4a lesions. METHODS: This prospective, multicenter study included 910 patients from nine different hospitals. The acquisition and analysis of conventional ultrasound and strain elastography (SE) were obtained by radiologists with more than 5 years of experience in breast ultrasound imaging. The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under curve (AUC) of conventional ultrasound alone and combined tests with ES and/or SR were calculated and compared. RESULTS: The optimal cutoff value of SR for differentiating benign from malignant masses was 2.27, with a sensitivity of 60.2% and a specificity of 84.8%. When combined with ES and SR, the AUC of the new BI-RADS classification increased from 0.733 to 0.824 (p < 0.001); the specificity increased from 48.1% to 68.5% (p < 0.001) without a decrease in the sensitivity (98.5% vs. 96.4%, p = 0.065); and the PPV increased from 52.2% to 63.7% (p < 0.001) without a loss in the NPV (98.2% vs. 97.1%, p = 0.327). All three combinations of conventional ultrasound, ES, and SR could reduce the biopsy rate of category 4a lesions without reducing the malignant rate of biopsy (from 100% to 68.3%, 34.9%, and 50.4%, respectively, all p < 0.001). CONCLUSIONS: SE can be used as a useful and non-invasive additional method to improve the diagnostic performance of conventional ultrasound by increasing AUC and specificity and reducing the unnecessary biopsy of BI-RADS 4a lesions.

Mesenchymal stem cell therapy in decompensated liver cirrhosis: a long-term follow-up analysis of the randomized controlled clinical trial.

BACKGROUND: Mesenchymal stem cell (MSC) infusion was reported to improve liver function in patients with decompensated liver cirrhosis (DLC); however, whether the medication can improve outcome of these patients is poorly understood. METHODS: This prospective, open-labeled, randomized controlled study enrolled 219 patients with HBV-related DLC who were divided into control group (n = 111) and umbilical cord-derived MSC (UC-MSC)-treated group (n = 108), then all of them received a follow-up check from October 2010 to October 2017. The treated patients received three times of UC-MSC infusions at 4-week intervals plus conventional treatment that was only used for control group. The overall survival rate and HCC-free survival rate were calculated as primary endpoints and the liver function and adverse events associated with the medication were also evaluated. RESULTS: During the follow-up check period from 13 to 75th months, there was a significantly higher overall survival rate in the treated group than the control group, while the difference of the hepatocellular carcinoma event-free survival rate between the treated and control groups was not observed during the 75-month follow-up. UC-MSC treatment markedly improved liver function, as indicated by the levels of serum albumin, prothrombin activity, cholinesterase, and total bilirubin during 48 weeks of follow-up. No significant side effects or treatment-related complications were observed in the UC-MSC group. CONCLUSIONS: Therapy of UC-MSC is not only well tolerated, but also significantly improves long-term survival rate, as well as the liver function in patients with HBV-related DLC. UC-MSC medication, therefore, might present a novel therapeutic approach for the disease.

The pharmacodynamic effect of terlipressin versus high-dose octreotide in reducing hepatic venous pressure gradient: a randomized controlled trial.

BACKGROUND: Vasoactive drugs can reduce portal venous pressure and control variceal bleeding. However, few studies have explored the hemodynamic effects of terlipressin and high-dose octreotide in such patients. Our purpose was to evaluate the hemodynamic changes and safety of using terlipressin and high-dose octreotide in patients with decompensated liver cirrhosis. METHODS: A multi-center randomized controlled trial was conducted. Cirrhotic patients with a history of variceal bleeding were included. Terlipressin or high-dose octreotide was administered during the procedure of measuring hepatic venous pressure gradient (HVPG). Hemodynamic parameters and symptoms were recorded. RESULTS: A total of 88 patients were included. HVPG was significantly reduced at 10, 20, and 30 min after drug administration in the terlipressin group (16.3±6.4 vs. 14.7±5.9, 14.0±6.1, and 13.8±6.1, respectively, P<0.001) and the high-dose octreotide group (17.4±6.6 vs. 15.1±5.8, 15.3±6.2, and 16.1±6.0, respectively P<0.01). Decreased heart rate and increased mean arterial pressure were more often observed in the terlipressin group. The overall response rates were not significantly different between the groups (52.8% vs. 44.8%, P=0.524). The terlipressin group had significantly higher response rates at 30 min compared to the high-dose octreotide group in those with alcoholic liver cirrhosis [6/6 (100%) vs. 0/4 (0%), P=0.005]. The incidence of adverse drug events was rare and similar in the two groups. CONCLUSIONS: Both terlipressin and high-dose octreotide were effective and safe for reducing HVPG. The pharmacodynamic effect of terlipressin persisted longer. The terlipressin group had higher response rates in those with alcoholic cirrhosis (trial number: NCT02119884).

Assessment of different modalities for repeated tissue acquisition in diagnosing malignant biliary strictures: A two-center retrospective study.

OBJECTIVE: Various modalities are applied for pathological diagnosis of malignant biliary strictures (MBS), including brush cytology (BC), forceps biopsy (FB) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). We aimed to assess the value of these modalities in a repeated tissue acquisition process for biliary strictures with initially inconclusive pathological outcomes. METHODS: Patients who were suspected of having MBS and underwent a BC in two large teaching hospitals were retrospectively included. The sensitivity, specificity, positive and negative predictive values, and accuracy of the initial and repeated BC, FB and EUS-FNA were analyzed. Their performances were compared to determine which modality was superior in repeated tissue acquisition. RESULTS: In total, 476 patients were included. The sensitivity, specificity and accuracy in diagnosing MBS for the initial BC were 30.3%, 100% and 55.0%, respectively. Altogether 39, 27 and 44 patients underwent a repeat BC, FB and EUS-FNA, respectively. The sensitivity for repeated BC, FB and EUS-FNA was 41.2%, 61.1% and 44.4%, respectively, whereas their specificity all reached 100%. When comparing diagnostic accuracy, none of the modalities was superior (74.4% vs 74.1% vs 54.5%, P = 0.173). In the repeated process, one patient who underwent BC and two underwent FB developed mild pancreatitis. CONCLUSIONS: Repeated tissue acquisition achieves a conclusive diagnosis of MBS in nearly half patients who have an initially inconclusive cytological diagnosis. None of the tissue acquisition methods is significantly superior in the repeated process.

The periscreen strip is an accurate and rapid method to diagnose spontaneous bacterial peritonitis among patients with acute-on-chronic liver failure.

BACKGROUND: Leukocyte esterase reagent strips may help diagnose spontaneous bacterial peritonitis (SBP), but their effective application among patients with acute-on-chronic liver failure (ACLF) remains unknown. AIM: This study aimed to assess the performance of periscreen strips in the rapid diagnosis of SBP among patients with ACLF. METHODS: Periscreen strips were used to test 261 ascites samples taken from 251 inpatients with ACLF between January 2014 and June 2019. The colors of the reagent strip were divided into four colorimetric graduations ('negative', 'trace', 'small', and 'large'), among which 'trace' is used as the SBP detection threshold. The polymorphonuclear neutrophils (PMN) of ascites ≥250/mm3 was used as the gold standard for SBP diagnosis. RESULTS: SBP was detected in 92 (35.2%) ascite samples. The ascites PMN count of 'negative' (32.5/mm3) was lower than those of 'trace' (248.2/mm3), 'small' (379.0/mm3), and 'large' (7426.0/mm3) (P < 0.001). The colorimetric graduations of the strips were positively correlated with ascites PMN count (r = 0.867, P < 0.001). Periscreen strips had 100% sensitivity, 91.1% specificity, 86.0% positive predictive value, 100% negative predictive value, 11.3 positive likelihood ratios, and 0 negative likelihood ratios. For patients with negative results judged by the gold standard, ascites white blood cells count [odds ratio (OR) = 1.007) and ascites PMN count (OR = 1.028) were independent predictors of false-positive cases. CONCLUSION: Liver failure did not affect the diagnostic performance of periscreen strips. Therefore, these strips can efficiently and rapidly diagnose SBP among patients with ACLF.

Substance P restores spermatogenesis in busulfan-treated mice: A new strategy for male infertility therapy.

Male infertility has become an important health problem that is primarily caused by testicular dysfunction with abnormal spermatogenesis. In this study, we demonstrated that the neuropeptide, substance P (SP), is essential for spermatogonia proliferation in a seminiferous tubule culture system. In addition, SP (5 nmol/kg) treatment markedly restored spermatogenesis, improved sperm quality, and increased the number of ZBTB16+ or LIN28+ undifferentiated spermatogonia as well as STRA8+ differentiated spermatogonia in a busulfan-induced non-obstructive azoospermic mouse model. Furthermore, 100 nM SP treatment in vitro significantly stimulated the proliferation of GC-1 spg cells (a spermatogonia cell line) via activation of the Erk1/2 signaling pathway. Moreover, the sperm quality and the number of spermatogonia were significantly reduced after treatment with RP67580, a selective NK-1 receptor antagonist, suggesting that SP-NK1R signaling plays an important role in spermatogenesis. Taken together, these results suggest that SP may be a potential therapeutic agent for male infertility by accelerating the restoration of spermatogenesis.

Infection deteriorating hepatitis B virus related acute-on-chronic liver failure: a retrospective cohort study.

BACKGROUND: Infection is common in acute-on-chronic liver failure (ACLF), which may worsen the clinical condition and prognosis. However, the characteristics of infection and its influence on prognosis in hepatitis B virus related ACLF (HBV-ACLF) as defined by the European Association for the Study of the Liver (EASL) have not been clarified. We aimed to investigate the characteristics of infection and its influence on mortality in patients with HBV-ACLF defined by EASL in China. METHODS: We performed a retrospective cohort study in patients with HBV-ACLF defined by EASL in a single center from January 2015 to December 2017. These patients were divided into two groups with and without infection. The incidence, sites of infection, isolated strains, and risk factors associated with mortality were evaluated. RESULTS: A total of 289 patients were included, among them 185 (64.0%) were diagnosed with an infection. The most common type of infection was pneumonia (55.7%), followed by spontaneous bacterial peritonitis (47.6%) and others. The gram-negative bacteria were the most frequent (58.3%). Patients with one, two, and three or more infection sites had a gradually increasing incidence of sepsis (P < 0.01), septic shock (P < 0.001), and ACLF-3 (P < 0.05). Also, patients with infection isolated one, two, and three or more strains showed a growing incidence of sepsis (P < 0.01) and septic shock (P < 0.001). Patients with infection showed a significantly higher 28-day mortality than those without (P < 0.01), especially in patients with ACLF-3. Infection was identified as an independent risk factor for 28-day mortality in all HBV-ACLF patients. Pneumonia and sepsis were identified as independent predictors of 28-day mortality for patients with infection. CONCLUSIONS: Infection is associated with severe clinical course and high mortality in HBV-ACLF defined by EASL. The increased number of infection sites or isolated strains was associated with the occurrence of sepsis and septic shock. Pneumonia and sepsis were independent predictors for mortality in HBV-ACLF patients with infection.

Clinical characteristics and 28-d outcomes of bacterial infections in patients with hepatitis B virus-related acute-on-chronic liver failure.

BACKGROUND: Acute-on-chronic liver failure (ACLF), which includes hepatic and multiple extra-hepatic organ failure, is a severe emergency condition that has high mortality. ACLF can rapidly progress and requires an urgent assessment of condition and referral for liver transplantation. Bacterial infections (BIs) trigger ACLF and play pivotal roles in the deterioration of clinical course. AIM: To investigate the clinical characteristics and 28-d outcomes of first BIs either at admission or during hospitalization in patients with hepatitis B virus (HBV)-ACLF as defined by the Chinese Group on the Study of Severe Hepatitis B (COSSH). METHODS: A total of 159 patients with HBV-ACLF and 40 patients with acute decompensation of HBV-related chronic liver disease combined with first BIs were selected for a retrospective analysis between October 2014 and March 2016. The characteristics of BIs, the 28-d transplant-free survival rates, and the independent predictors of the 28-d outcomes were evaluated. RESULTS: A total of 194 episodes of BIs occurred in 159 patients with HBV-ACLF. Among the episodes, 13.4% were community-acquired, 46.4% were healthcare-associated, and 40.2% belonged to nosocomial BIs. Pneumonia (40.7%), spontaneous bacterial peritonitis (SBP) (34.5%), and bloodstream infection (BSI) (13.4%) were the most prevalent. As the ACLF grade increased, the incidence of SBP showed a downward trend (P = 0.021). Sixty-one strains of bacteria, including 83.6% Gram-negative bacteria and 29.5% multidrug-resistant organisms, were cultivated from 50 patients with ACLF. Escherichia coli (44.3%) and Klebsiella pneumoniae (23.0%) were the most common bacteria. As the ACLF grade increased, the 28-d transplant-free survival rates showed a downward trend (ACLF-1, 55.7%; ACLF-2, 29.3%; ACLF-3, 5.4%; P < 0.001). The independent predictors of the 28-d outcomes of patients with HBV-ACLF were COSSH-ACLF score (hazard ratio [HR] = 1.371), acute kidney injury (HR = 2.187), BSI (HR = 2.339), prothrombin activity (HR = 0.967), and invasive catheterization (HR = 2.173). CONCLUSION: For patients with HBV-ACLF combined with first BIs, pneumonia is the most common form, and the incidence of SBP decreases with increasing ACLF grade. COSSH-ACLF score, acute kidney injury, BSI, prothrombin activity, and invasive catheterization are the independent predictors of 28-d outcomes.

High-dependency units play a key role in the treatment of a Chinese military patient who developed liver failure while abroad.

High-dependency units (HDUs) provide high-level care to patients who suffer from single organ failure, with the exception of respiratory failure requiring mechanical ventilation; HDUs serve as an intermediary between general wards and Intensive Care Units. Due to military and civilian needs, our hospital has established a unique HDU for patients with liver disease in China. A Chinese military officer in the United Nations Peacekeeping Forces in South Sudan was transferred to our HDU for liver failure treatment in 2018. The patient's disease status, nutrition, sleep habits, and psychological behaviour were monitored on different scales. The patient was provided with vascular monitoring, telemetry, pulse oximetry, drug treatment, nutritional support, sleep intervention, psychological intervention, and humanistic care by a multidisciplinary treatment team. After treatment, the patient recovered and avoided liver transplantation. Based on the experience with this HDU, this new model may create an efficient treatment process for military and civilian patients with severe liver disease at home or abroad.

Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure.

BACKGROUND: As a large, prospective, multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score (COSSH-ACLFs), has been approved by some foreign scholars; however, its predictive value needs to be verified. This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF. METHODS: This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014. Spearman method was used to assess the correlation of COSSH-ACLFs with classical scores. Different COX multivariate regression models were used to confirm the relationship between COSSH-ACLFs and short-term prognosis in patients with HBV-ACLF, and stratified analysis was used to further verify the stability of this relationship. We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve (AUROC) and Z-test. RESULTS: A total of 975 patients with HBV-ACLF were screened, and 751 were analyzed (623 male and 128 female). COSSH-ACLFs was the highest in patients with end-stage ACLF, followed by those with middle- and early-stage ACLF (H = 211.8, P < 0.001). In the fully adjusted model, COX multivariate regression analysis revealed that COSSH-ACLFs (as a continuous variable) was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days (hazard ratio [HR]: 1.37 [1.22, 1.53], P < 0.001) and 90 days (HR: 1.43 [1.29, 1.58], P < 0.001). The same trend could be observed in the crude model and minimally adjusted model. The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792, respectively, indicating a stronger predictive accuracy than those of classic models. CONCLUSIONS: COSSH-ACLFs, with a superior predictive accuracy compared with other classical scores, can strongly predict short-term prognosis in Chinese patients with HBV-ACLF.

The correlation between LIN28B gene potentially functional variants and Wilms tumor susceptibility in Chinese children.

BACKGROUND: Wilms tumor (WT) is the most common urologic cancer in children. However, genetic bases underlying WT remain largely unknown. Previous studies indicated that Lin28 homolog B (LIN28B) level is significantly elevated in some WTs. Enforced expression of Lin28b during kidney development could induce WT. Genetic variations in the LIN28B gene may be related to WT susceptibility. METHOD: In this study, we aimed to assess the association between LIN28B gene polymorphisms and WT susceptibility in Chinese children. Four potentially functional polymorphisms in the LIN28B gene (rs314276 C>A, rs221634 A>T, rs221635 T>C and rs9404590 T>G) were genotyped in 145 cases and 531 cancer-free controls, using Taqman method. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the associations. RESULTS: Our results showed that the rs314276 CA genotype was associated with a decreased WT risk (CA vs CC: adjusted OR=0.65, 95% CI=0.43-0.98, P=.042). Moreover, we found that carriers of the 1-3 risk genotypes had a significantly increased WT risk when compared to the non-carriers (adjusted OR=1.51, 95% CI=1.03-2.20, P=.035). The association with risk genotypes was more predominant in children 18 month old or younger and in females. CONCLUSION: In summary, these results indicated that the LIN28B gene rs314276 C>A polymorphism alone and three combined polymorphisms may be able to modify WT susceptibility in Southern Chinese children. Our findings call for further validation in large studies with different ethnicities involved.

Differential characteristics and prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure defined by European Association for the Study of the Liver - Chronic Liver Failure criteria.

AIM: To determine the differential characteristics and prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) detected using Asian Pacific Association for the Study of the Liver (APASL) criteria and then classified using European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) criteria. METHODS: We retrospectively reviewed 316 HBV-related APASL ACLF patients treated at Beijing 302 Hospital or Beijing You'An Hospital (both Beijing, China) between February 2015 and February 2016. Clinical characteristics and mortality rates were compared among patients with different EASL-CLIF ACLF severity grades (no ACLF, and ACLF grades 1-3). RESULTS: According to the EASL-CLIF criteria, 138 patients had no ACLF, 123 had ACLF at enrollment, and 55 developed ACLF during hospitalization. Both 28-day and 90-day transplant-free mortality were dramatically lower in patients without EASL-CLIF ACLF (0.7% and 5.1%, respectively) than in patients with EASL-CLIF ACLF (40.7% and 63.2%, respectively; both P < 0.001). Liver failure rates were similar in patients with and without EASL-CLIF ACLF, but extrahepatic organ failure was rare in patients without EASL-CLIF ACLF. Baseline serum creatinine, new bacterial infection and new acute kidney injury during hospitalization, maximum rising rates of CLIF-C ACLF score, and Model for End-stage Liver Disease score were independent predictors of EASL-CLIF ACLF after enrollment. CONCLUSIONS: The EASL-CLIF ACLF classification can accurately prognosticate the short-term mortality of patients with HBV-related APASL ACLF. It can also distinguish distinct clinical characteristics and prognoses in patients with and without EASL-CLIF ACLF.

Associations between LMO1 gene polymorphisms and Wilms' tumor susceptibility.

Wilms' tumor is the most common childhood renal malignancy. A genome-wide association study identified LIM domain only 1 (LMO1) as having oncogenic potential. We examined the associations between LMO1 gene polymorphisms and susceptibility to Wilms' tumor. In this hospital-based, case-control study, we recruited 145 children with Wilms' tumor and 531 cancer-free children. Four polymorphisms (rs110419 A>G, rs4758051 G>A, rs10840002 A>G and rs204938 A>G) were genotyped using Taqman methodology. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to measure the associations between selected polymorphisms and Wilms' tumor susceptibility. Only rs110419 AG was found to be protective against Wilms' tumor (adjusted OR = 0.62, 95% CI = 0.41-0.94, P = 0.024) when compared to rs110419 AA. Wilms' tumor risk was markedly greater in children with 1-4 risk genotypes (nucleotide alterations) than in those with no risk genotypes (adjusted OR = 1.84, 95% CI = 1.25-2.69, P = 0.002). In a stratified analysis, the protective effect of rs110419 AG/GG was predominant in males. The association of 1-4 risk genotypes with Wilms' tumor risk was limited to subgroups of children who were >18 months old, female, and in clinical stages III+IV. Thus, LMO1 gene polymorphisms may contribute to Wilms' tumor risk, but this conclusion should be validated in other populations and larger studies.

BARD1 Gene Polymorphisms Confer Nephroblastoma Susceptibility.

BRCA1-associated RING domain protein 1 (BARD1) is a tumor suppressor, which forms a heterodimer with BRCA1. Three BARD1 gene polymorphisms (rs7585356 G>A, rs6435862 T>G and rs3768716 A>G) were initially identified as high-risk neuroblastoma susceptibility loci by a previous GWAS. Because of the general tumor-suppressing function of BARD1, we hypothesized that these BARD1 gene polymorphisms might modify the susceptibility to nephroblastoma. We genotyped these polymorphisms in 145 cases and 531 controls using Taqman methods. Out of three polymorphisms, only the rs7585356 G>A polymorphism was significantly associated with increased susceptibility to nephroblastoma [AA vs. GG: adjusted odds ratio (OR)=1.78, 95% confidence interval (CI)=1.01-3.12]. Combined analysis of three polymorphisms indicated that subjects with 3 risk genotypes exhibited significantly elevated nephroblastoma risk, when compared with subjects with 0-2 risk genotypes (adjusted OR=1.72, 95% CI=1.02-2.89). Stratified analysis revealed that in term of clinical stage, rs7585356 AA carriers were associated with increased risk of developing clinical stage I+II nephroblastoma. The presence of three risk genotypes was significantly associated with nephroblastoma risk in females and clinical stage I+II nephroblastoma. Our results suggested that BARD1 rs7585356 G>A may be associated with nephroblastoma risk.

NFKB1 -94insertion/deletion ATTG polymorphism and cancer risk: Evidence from 50 case-control studies.

Nuclear factor-kappa B1 (NF-κB1) is a pleiotropic transcription factor and key contributor to tumorigenesis in many types of cancer. Numerous studies have addressed the association of a functional insertion (I)/deletion (D) polymorphism (-94ins/delATTG, rs28362491) in the promoter region of NFKB1 gene with the risk of various types of cancer; however, their conclusions have been inconsistent. We therefore conducted a meta-analysis to reevaluate this association. PubMed, EMBASE, China National Knowledge infrastructure (CNKI), and WANFANG databases were searched through July 2016 to retrieve relevant studies. After careful assessment, 50 case-control studies, comprising 18,299 cases and 23,484 controls were selected. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were used to determine the strength of the association. The NFKB1 -94ins/delATTG polymorphism was associated with a decreased risk of overall cancer in the homozygote model (DD vs. II): OR = 0.75, 95% CI = 0.64-0.87); heterozygote model (ID vs. II): OR = 0.91, 95% CI = 0.83-0.99; recessive model (DD vs. ID/II): OR = 0.81, 95% CI = 0.71-0.91; dominant model (ID/DD vs. II): OR = 0.86, 95% CI = 0.78-0.95; and allele contrast model (D vs. I): OR = 0.88, 95% CI = 0.81-0.95). Subgroup and stratified analyses revealed decreased risks for lung cancer, nasopharyngeal carcinoma, prostate cancer, ovarian cancer, and oral squamous cell carcinoma, and this association held true also for Asians (especially Chinese subjects) in hospital-based studies, and in studies with quality scores less than nine. Well-designed, large-scale case-control studies are needed to confirm these results.
