Efficacy of endoscopic therapy combined with partial splenic embolization versus Hassab's operation for patients with liver cirrhosis with esophageal variceal bleeding and hypersplenism: a multicenter cohort study based on propensity score matching.

BACKGROUND: The prognosis comparison between endoscopic therapy + partial splenic embolization (PSE) and Hassab's operation is unclear in the treatment of esophageal variceal bleeding in patients with liver cirrhosis. This study aimed to compare the outcome of endoscopic therapy + PSE (EP) with a combination of splenectomy + pericardial devascularization procedure, known as Hassab's operation (SH) for esophageal variceal bleeding in patients with liver cirrhosis with hypersplenism. METHODS: We enrolled 328 patients, including 125 and 203 patients who underwent EP and SH, respectively. Each group consisted of 110 patients after propensity score matching (PSM). Subsequently, we recorded and analyzed bleeding episodes and mortality in 6 months and 1, 2, and 5 years after therapies. RESULTS: The median follow-up time in the EP and SH groups was 53 and 64 months, respectively. Bleeding incidence 6 months after therapies in the EP group was lower than that in the SH group (1.8% vs. 10.0%, P = 0.010). Additionally, complications in the perioperative period were not significantly different (0% vs. 3.6%, P = 0.008). However, the bleeding rate between the two groups was not significantly different at 1, 2, and 5 years after therapies (7.3% vs. 12.7%, P = 0.157; 10.9% vs. 16.4%, P = 0.205; 30.6% vs. 31.8%, P = 0.801), as well as mortality rate (4.5% vs 7.3%, P = 0.571). CONCLUSION: Compared with SH therapy, the bleeding rate 6 months after EP therapy was lower, but the long-term bleeding rate was similar.

Influence of subcutaneous adipose tissue index on prognosis in cirrhotic patients following endoscopic therapy: a retrospective cohort study.

BACKGROUND: The relation of adipose tissue depletion with prognostic outcome of variceal bleeding among cirrhotic patients is still inconclusive. The present work explored whether adipose tissue, which was measured based on computed tomography (CT), was valuable for analyzing rebleeding and mortality among patients with variceal bleeding who had undergone endoscopic therapy. METHODS: The study encompassed cirrhotic patients who underwent endoscopic therapy to prevent variceal rebleeding between January 2016 and October 2022. The L3-level CT images were obtained. Besides, impacts of subcutaneous adipose tissue index (SATI), visceral adipose tissue index (VATI), as well as total adipose tissue index (TATI) on rebleeding and mortality among cirrhotic patients following endoscopic therapy were examined. RESULTS: In this work, our median follow-up period was 31 months. Among those adipose tissue indexes, only SATI exhibited an independent relation to higher rebleeding (HR 0.981, 95% CI, 0.971-0.991, p < 0.001) and mortality (HR 0.965, 95% CI, 0.944-0.986, p = 0.001) risks. Upon multivariate Cox regression, low SATI (male < 30.15 cm2/m2, female < 39.82 cm2/m2) was independently linked to higher rebleeding risk (HR 2.511, 95% CI, 1.604-3.932, p < 0.001) and increased mortality risk (HR 3.422, 95% CI, 1.489-7.864, p = 0.004) after adjusting for other predictors. Furthermore, subgroups were created based on using nonselective ß-blockers (NSBBs), demonstrating that quantitatively assessing SATI exerts a vital role in evaluating rebleeding incidence in patients with or without NSBB therapy. CONCLUSION: This study underscores the potential of quantifying SATI as a means for achieving a more accurate risk classification for individual patients and identifying patients that can gain more benefits from nutritional intervention.

Association between the severity of metabolic dysfunction-associated fatty liver disease and the risk of colorectal neoplasm: a systematic review and meta-analysis.

BACKGROUND: The severity of metabolic dysfunction-associated fatty liver disease (MAFLD) reportedly plays a part in the etiology of colorectal tumors. However, there is no consensus. METHODS: Studies relevant with the impact of MAFLD severity on the risk of colorectal neoplasms published before 24th April 2022 were screened. The pooled odds ratio (OR) with corresponding 95% confidence intervals (95% CI) was obtained using standard and cumulative meta-analyses. Subgroup, meta-regression, and sensitivity analyses were carried out to identify heterogeneity. RESULTS: Fourteen studies with data from 37,824 MAFLD patients were included. The prevalence of colorectal neoplasms escalated with the progression of MAFLD compared to simple steatosis (OR = 1.93; 95% CI = 1.42-2.62). The magnitude and direction of the effect on these outcomes remained largely constant over time. Even after limiting the meta-analysis to 8 studies with available adjusted OR (aOR), the findings still suggested that MAFLD severity was positively related to colorectal neoplasms (aOR = 3.03; 95% CI = 2.02-4.53). Severe MAFLD was more likely to cause left colon tumors (OR = 3.86, 95% CI = 2.16-6.91) than right colon neoplasms (OR = 1.94, 95% CI = 1.15-3.28). CONCLUSION: The severity of MAFLD was independently related to colorectal neoplasms and severe MAFLD was more likely to cause left colon tumors.

[A multicenter survey of antibiotic use in very and extremely low birth weight infants in Hunan Province].

OBJECTIVE: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province. METHODS: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017. RESULTS: The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (rs=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (rs=0.196, P<0.01). CONCLUSIONS: Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

Impact of sarcopenia on variceal rebleeding in patients after endoscopic therapy: a multicenter retrospective cohort study based on propensity score matching.

BACKGROUND: Sarcopenia is a common complication of liver cirrhosis and can be used for predicting dismal prognostic outcomes. This study aimed to evaluate the role of sarcopenia in rebleeding and mortality of liver cirrhosis patients after endoscopic therapy. METHODS: The liver cirrhosis patients who received endoscopic treatment were enrolled. Propensity score matching (PSM) was used to overcome selection bias. Two-year rebleeding episodes and mortality after endoscopic therapy were recorded. RESULTS: A total of 109 (32.4%) sarcopenia patients were reported. Before PSM, the frequency of rebleeding was significantly higher in the sarcopenia group relative to the non-sarcopenia group (41.3% vs. 15.9%, p < 0.001). Moreover, the multivariable analysis revealed that sarcopenia (p < 0.001, HR:2.596, 95% CI 1.591-4.237) was independently associated with a 2-year rebleeding episode. After PSM, the sarcopenia group exhibited an increased rebleeding rate as compared with non-sarcopenia group (44.4% vs. 15.3%, p < 0.001). According to multivariable analysis, sarcopenia (p < 0.001, HR:3.490, 95% CI 1.756-6.938) was identified as a significant predictor for 2-year rebleeding. CONCLUSION: Sarcopenia was significantly associated with a high 2-year rebleeding rate in liver cirrhosis patients after endoscopic treatment. Therefore, the precise evaluation of a patient's nutritional status, including sarcopenia becomes mandatory before endoscopic treatment.

Development and validation of a predictive model for submucosal fibrosis in patients with early gastric cancer undergoing endoscopic submucosal dissection: experience from a large tertiary center.

BACKGROUND: Submucosal fibrosis is associated with adverse events of endoscopic submucosal dissection (ESD). The present study mainly aimed to establish a predictive model for submucosal fibrosis in patients with early gastric cancer (EGC) undergoing ESD. METHODS: Eligible patients with EGC, identified at Qilu Hospital of Shandong University from April 2013 to December 2023, were retrospectively included and randomly split into a training set and a validation set in a 7:3 ratio. Logistic regression analyses were used to pinpoint the risk factors for submucosal fibrosis. A nomogram was developed and confirmed using receiver operating characteristic (ROC) curves, calibration plots, Hosmer-Lemeshow (H-L) tests, and decision curve analysis (DCA) curves. Besides, a predictive model for severe submucosal fibrosis was further conducted and tested. RESULTS: A total of 516 cases in the training group and 220 cases in the validation group were recruited. The nomogram for submucosal fibrosis contained the following items: tumour location (long axis), tumour location (short axis), ulceration, and biopsy pathology. ROC curves showed high efficiency with an area under the ROC of 0.819 in the training group, and 0.812 in the validation group. Calibration curves and H-L tests indicated good consistency. DCA proved the nomogram to be clinically beneficial. Furthermore, the four items were also applicable for a nomogram predicting severe fibrosis, and the model performed well. CONCLUSION: The predictive models, initially constructed in this study, were validated as convenient and feasible for endoscopists to predict submucosal fibrosis and severe fibrosis in patients with EGC undergoing ESD.

Partial splenic embolization combined with endoscopic therapies and vasoconstrictive drugs reduces rebleeding in cirrhosis patients with acute variceal bleeding and hypersplenism: a multicenter randomized controlled trial.

BACKGROUND: This study aimed to compare the efficacy of partial splenic embolization (PSE) combined with endoscopic therapy and endoscopic therapy alone in cirrhosis patients with acute variceal bleeding (AVB) and hypersplenism. METHODS: Cirrhosis patients with AVB who visited three hospitals from June 2016 to June 2022 were prospectively enrolled and randomly allocated to either the endoscopic therapy combined with PSE group (EP group) or the endoscopic intervention group (E group) in a 1:1 ratio. The primary endpoint of the study was re-bleeding of varices during follow-up, and the secondary endpoints were the recurrence of varices, death, and adverse events. RESULTS: One hundred and fourteen patients were prospectively included, of whom 110 completed the trial. The risk of variceal re-bleeding (19.3% vs. 40.4% (23/57), p = 0.013) and variceal recurrence (28.1% vs. 63.2%, p < 0.001) five years after treatment was significantly lower in the EP group than in the E group, and the EP treatment was the only significant independent risk factor affecting variceal re-bleeding and variceal recurrence in patients. The mortality rate was comparable between the EP and E groups. Peripheral blood counts and liver function all improved significantly in the EP group compared to the E group during the follow-up (p < 0.05). CONCLUSIONS: The rates of variceal re-bleeding and recurrence were significantly lower in cirrhosis patients with AVB and hypersplenism after combined endoscopic and PSE treatment compared to those who were provided endoscopic treatment only. The peripheral blood counts and liver function were also improved significantly in EP group (NCT02778425).
