A Systematic Review of the Potential Chemoprotective Effects of Resveratrol on Doxorubicin-Induced Cardiotoxicity: Focus on the Antioxidant, Antiapoptotic, and Anti-Inflammatory Activities.
PURPOSE
Although doxorubicin chemotherapeutic drug is commonly used to treat various solid and hematological tumors, its clinical use is restricted because of its adverse effects on the normal cells/tissues, especially cardiotoxicity. The use of resveratrol may mitigate the doxorubicin-induced cardiotoxic effects. For this aim, we systematically reviewed the potential chemoprotective effects of resveratrol against the doxorubicin-induced cardiotoxicity.
METHODS
In the current study, a systematic search was performed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for the identification of all relevant studies on "the role of resveratrol on doxorubicin-induced cardiotoxicity" in the electronic databases of Web of Science, PubMed, and Scopus up to March 2021 using search terms in their titles and abstracts. Two hundred and eighteen articles were screened in accordance with a predefined set of inclusion and exclusion criteria. Finally, 33 eligible articles were included in this systematic review.
RESULTS
The and findings demonstrated a decreased cell survival, increased mortality, decreased heart weight, and increased ascites in the doxorubicin-treated groups compared to the control groups. The combined treatment of resveratrol and doxorubicin showed an opposite pattern than the doxorubicin-treated groups alone. Furthermore, this chemotherapeutic agent induced the biochemical and histopathological changes on the cardiac cells/tissue; however, the results (for most of the cases) revealed that these alterations induced by doxorubicin were reversed near to normal levels (control groups) by resveratrol coadministration.
CONCLUSION
The results of this systematic review stated that coadministration of resveratrol alleviates the doxorubicin-induced cardiotoxicity. Resveratrol exerts these chemoprotective effects through several main mechanisms of antioxidant, antiapoptosis, and anti-inflammatory.

Review
BACKGROUND
Vitamin D deficiency is often reported in people with chronic liver diseases. Improving vitamin D status could therefore be beneficial for people with chronic liver diseases.
OBJECTIVES
To assess the beneficial and harmful effects of vitamin D supplementation in adults with chronic liver diseases.
SEARCH METHODS
We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, Science Citation Index Expanded, and Conference Proceedings Citation Index-Science. We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. We scanned bibliographies of relevant publications and enquired experts and pharmaceutical companies as to additional trials. All searches were up to November 2020.
SELECTION CRITERIA
Randomised clinical trials that compared vitamin D at any dose, duration, and route of administration versus placebo or no intervention in adults with chronic liver diseases. Vitamin D could have been administered as supplemental vitamin D (vitamin D (cholecalciferol) or vitamin D (ergocalciferol)), or an active form of vitamin D (1α-hydroxyvitamin D (alfacalcidol), 25-hydroxyvitamin D (calcidiol), or 1,25-dihydroxyvitamin D (calcitriol)).
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of evidence.
MAIN RESULTS
We included 27 randomised clinical trials with 1979 adult participants. This review update added 12 trials with 945 participants. We assessed all trials as at high risk of bias. All trials had a parallel-group design. Eleven trials were conducted in high-income countries and 16 trials in middle-income countries. Ten trials included participants with chronic hepatitis C, five trials participants with liver cirrhosis, 11 trials participants with non-alcoholic fatty liver disease, and one trial liver transplant recipients. All of the included trials reported the baseline vitamin D status of participants. Participants in nine trials had baseline serum 25-hydroxyvitamin D levels at or above vitamin D adequacy (20 ng/mL), whilst participants in the remaining 18 trials were vitamin D insufficient (less than 20 ng/mL). Twenty-four trials administered vitamin D orally, two trials intramuscularly, and one trial intramuscularly and orally. In all 27 trials, the mean duration of vitamin D supplementation was 6 months, and the mean follow-up of participants from randomisation was 7 months. Twenty trials (1592 participants; 44% women; mean age 48 years) tested vitamin D (cholecalciferol); three trials (156 participants; 28% women; mean age 54 years) tested vitamin D; four trials (291 participants; 60% women; mean age 52 years) tested 1,25-dihydroxyvitamin D; and one trial (18 participants; 0% women; mean age 52 years) tested 25-hydroxyvitamin D. One trial did not report the form of vitamin D. Twelve trials used a placebo, whilst the other 15 trials used no intervention in the control group. Fourteen trials appeared to be free of vested interest. Eleven trials did not provide any information on clinical trial support or sponsorship. Two trials were funded by industry. We are very uncertain regarding the effect of vitamin D versus placebo or no intervention on all-cause mortality (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.51 to 1.45; 27 trials; 1979 participants). The mean follow-up was 7 months (range 1 to 18 months). We are very uncertain regarding the effect of vitamin D versus placebo or no intervention on liver-related mortality (RR 1.62, 95% CI 0.08 to 34.66; 1 trial; 18 participants) (follow-up: 12 months); serious adverse events such as hypercalcaemia (RR 5.00, 95% CI 0.25 to 100.8; 1 trial; 76 participants); myocardial infarction (RR 0.75, 95% CI 0.08 to 6.81; 2 trials; 86 participants); thyroiditis (RR 0.33, 95% CI 0.01 to 7.91; 1 trial; 68 participants); circular haemorrhoidal prolapse (RR 3.00, 95% CI 0.14 to 65.9; 1 trial; 20 participants); bronchopneumonia (RR 0.33, 95% CI 0.02 to 7.32; 1 trial 20 participants); and non-serious adverse events. The certainty of evidence for all outcomes is very low. We found no data on liver-related morbidity such as gastrointestinal bleeding, hepatic encephalopathy, hepatorenal syndrome, ascites, or liver cancer. There were also no data on health-related quality of life. The evidence is also very uncertain regarding the effect of vitamin D versus placebo or no intervention on rapid, early, and sustained virological response in people with chronic hepatitis C.
AUTHORS' CONCLUSIONS
Given the high risk of bias and insufficient power of the included trials and the very low certainty of the available evidence, vitamin D supplementation versus placebo or no intervention may increase or reduce all-cause mortality, liver-related mortality, serious adverse events, or non-serious adverse events in adults with chronic liver diseases. There is a lack of data on liver-related morbidity and health-related quality of life. Further evidence on clinically important outcomes analysed in this review is needed.

World Journal of Clinical Cases Jul 2021The impact of type 2 diabetes mellitus (T2DM) on the prognosis and complications of liver cirrhosis is not fully clarified.
BACKGROUND
The impact of type 2 diabetes mellitus (T2DM) on the prognosis and complications of liver cirrhosis is not fully clarified.
AIM
To clarify the mortality and related risk factors as well as complications in cirrhotic patients with T2DM.
METHODS
We searched PubMed, EMBASE, and the Cochrane Library from their inception to December 1, 2020 for cohort studies comparing liver transplant-free mortality, hepatocellular carcinoma (HCC), ascites, spontaneous bacterial peritonitis (SBP), variceal bleeding, and hepatic encephalopathy (HE) in cirrhotic patients with without T2DM. Odds ratios (ORs) were combined by using fixed-effects or random-effects models with RevMan software.
RESULTS
The database search generated a total of 17 cohort studies that met the inclusion criteria. Among these studies, eight reported the risk of mortality, and eight reported the risk of HCC. Three studies provided SBP rates, and two documented ascites rates. Four articles focused on HE rates, and three focused on variceal bleeding rates. Meta-analysis indicated that T2DM was significantly associated with an increased risk of liver transplant-free mortality [OR: 1.28, 95% confidence intervals (CI): 1.16-1.41, < 0.0001] and HCC incidence (OR: 1.82, 95%CI: 1.32-2.51, = 0.003). The risk of SBP was not significantly increased (OR: 1.16 95%CI: 0.86-1.57, = 0.34). Additionally, T2DM did not significantly increase HE (OR: 1.31 95%CI: 0.97-1.77, = 0.08), ascites (OR: 1.11 95%CI: 0.84-1.46, = 0.46), and variceal bleeding (OR: 1.34, 95%CI: 0.99-1.82, = 0.06).
CONCLUSION
The findings suggest that cirrhotic patients with T2DM have a poor prognosis and high risk of HCC. T2DM may not be associated with an increased risk of SBP, variceal bleeding, ascites, or HE in cirrhotic patients with T2DM.

This study aims to analyze the patient profile and presentation of endometriosis-related hemorrhagic ascites and review its management to raise awareness among gynecologists and improve treatment strategies. We present a case report and engage in a systematic review involving human cases of histologically proven endometriosis with hemorrhagic ascites. Keywords were searched in PubMed/MEDLINE, Cochrane Library, EMBASE, and Ovid Discovery databases from inception until December 2018. Studies that did not include a description of ascites or histopathologic results confirming endometriosis or those that involved patients with other conditions that may contribute to ascites were excluded. The review yielded 73 articles describing 84 premenopausal women with histologically proven endometriosis-related hemorrhagic ascites. Of note, 83% (65/78) of the patients were nulliparous and 69.35% (43/62) were of African descent. The most common chief complaint was abdominal enlargement (58.33%, 49/84) but a host of other symptoms were also reported. Pleural effusion was reported in 32.14% (27/84), and elevated CA-125 was seen in 74.42% (32/43). The majority (64.29%, 54/84) of the patients underwent laparotomy, and an increasing trend of minimally invasive surgical approaches (p<0.001) and fertility-sparing techniques (p<0.001) was observed. The mean ascites volume was 4228.27 mL (SD: 2625.66). Moderate to severe endometriosis was seen in 97.44% (76/78) of cases. The majority of the patients who received medical treatment were given gonadotropin-releasing hormone (GnRH) agonists (63.79%, 37/58). The rate of recurrence after termination or suppression of ovarian function was 8.33% (7/84), and there was a mortality rate of 1.19% (1/84). Diagnosis of endometriosis-related hemorrhagic ascites may be challenging because it mimics several disease entities that cause ascites, thereby warranting a heightened clinical suspicion. Minimally invasive techniques are usually employed to establish a histologic diagnosis. The prevention of recurrence involves the recognition of endometriosis-related hemorrhagic ascites as a manifestation of severe endometriosis, which should prompt therapies directed at suppressing ovarian function. Since affected women are of childbearing age, ovary-preserving surgeries are generally preferred. The rate of recurrence is low after appropriate surgical and medical interventions.

Florence Nightingale Journal of Nursing Jun 2021This systematic review aimed to evaluate the efficacy of preventive and therapeutic approaches used in the management of ascites in liver cirrhosis. (Review)
Review
AIM
This systematic review aimed to evaluate the efficacy of preventive and therapeutic approaches used in the management of ascites in liver cirrhosis.
METHOD
Literature review was done in "Scopus, Web of Science, CINAHL, ScienceDirect, PubMed MEDLINE, Ulakbim National Database, and Cochrane Library" databases using the keywords, "ascites, refractory ascites, liver cirrhosis, intervention, prophylaxis, treatment, nursing management, prevention, ascites management, randomized controlled trials," and 2,447 articles were obtained. The studies with low bias risk were included. This systematic review was planned by following the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015 statement.
RESULTS
A total of 11 randomized controlled trials were included. When the included studies were examined, ascites treatment approaches were evaluated in all of the studies; however, preventive approaches were not evaluated. It was found that mannitol, a diuretic drug, helps ascites management by contributing to weight loss, decrease in abdominal circumference, and urinary sodium excretion. The automatic low-flow ascites pump also reduced the need for large-volume paracentesis. There was a decrease in weight and abdominal circumference measurements when band compression was applied to the umbilicus.
CONCLUSION
Therapeutic approaches were found to be effective. It was thought that the lack of nursing practices and the prevention of ascites formation in the abdomen was an important deficiency. Randomized controlled trials were recommended for the prevention of abdominal ascites formation and the side effects of treatment on the patient.

Review
BACKGROUND AND AIM
Spontaneous bacterial peritonitis is a potentially life-threatening infection in patients with liver cirrhosis and ascites. Its prevention is vital to improve prognosis of cirrhotic patients. The main objective of this systematic review was to evaluate what is the most efficacious and safest antibiotic prophylactic strategy.
METHODS
Studies were located by searching PubMed and Cochrane Central Register of Controlled Trials in The Cochrane Library until February 2019. Randomized controlled trials evaluating primary or secondary spontaneous bacterial peritonitis prophylaxis in cirrhotic patients with ascites were included. The selection of studies was performed in two stages: screening of titles and abstracts, and assessment of the full papers identified as relevant, considering the inclusion criteria. Data were extracted in a standardized way and synthesized qualitatively.
RESULTS
Fourteen studies were included. This systematic review demonstrated that daily norfloxacin is effective as a prophylactic antibiotic for the prevention of spontaneous bacterial peritonitis in patients with cirrhosis. Once weekly ciprofloxacin was not inferior to once daily norfloxacin, with good tolerance and no induced resistance. Trimethoprim-sulfamethoxazole and norfloxacin have similar efficacy for primary and secondary prophylaxis of spontaneous bacterial peritonitis, however, trimethoprim-sulfamethoxazole was associated with an increased risk of developing an adverse event. Rifaximin was more effective than norfloxacin in the secondary prophylaxis of spontaneous bacterial peritonitis, with a significant decrease in adverse events and mortality rate.
CONCLUSIONS
Continuous long-term selective intestinal decontamination with norfloxacin is the most widely used prophylactic strategy in spontaneous bacterial peritonitis, yet other equally effective and safe options are available.

World Journal of Gastrointestinal... Jun 2021Chylous ascites is a rare complication in colorectal surgery with limited evidence.
BACKGROUND
Chylous ascites is a rare complication in colorectal surgery with limited evidence.
AIM
To systematically review all available evidence to describe the incidence, clinical presentation, risk factors and management strategies.
METHODS
The systematic review was performed through PubMed, MEDLINE, EMBASE and Cochrane and cross-checked up to November 2020. The data collated included: Demographics, indications (benign malignant), site of disease, surgical approach, extent of lymphadenectomy, day to and method of diagnosis of chylous ascites and management strategies.
RESULTS
A total of 28 studies were included in the final analysis (426 cases). Patient age ranged from 31 to 89 years. All except one case were performed for malignancy. Of the 426 cases, 195 were right-colonic, 121 left-colonic, 103 pelvic surgeries and 7 others. The majority were diagnosed during the same inpatient stay by recognition of typical drain appearance and increased volume. Three cases were diagnosed during outpatient visits with increased abdominal distention and subsequently underwent paracentesis. Most cases were managed successfully non-operatively (fasting with prolonged drainage, total parenteral nutrition, somatostatin analogues or a combination of these). Only three cases required surgical intervention after failing conservative management and subsequently resolved completely. Risk factors identified include: Right-colonic surgery/ tumour location, extent of lymphadenectomy and number of lymph nodes harvested.
CONCLUSION
Chylous ascites after colorectal surgery is a relatively rare complication. Whilst the majority of cases resolved without surgical intervention, preventative measures should be undertaken such as meticulous dissection and clipping of lymphatics during lymphadenectomy to prevent morbidity.

Review
INTRODUCTION
Gastrointestinal involvement is a common complain observed in 40-60% of systemic lupus erythematosus (SLE) patients. We performed a systematic review of clinically severe and potential life-threatening gastrointestinal manifestations and discuss clinical presentation, pathogenesis and treatment.
METHODS
We performed a literature search in English literature using PubMed and Embase from 2000 to December 2020. The following MeSH terms: systemic lupus erythematosus, protein-losing enteropathy, ascites, pancreatitis, vasculitis, intestinal vasculitis, enteritis and diarrhea published in the English literature.
RESULTS
We identified 141 studies (case reports, case series and cohort studies). The most frequent presenting symptoms are acute abdominal pain, nausea, and vomiting. Many of the manifestations were associated with disease activity. Histological features are rarely available, but both vasculitis and thrombosis have been described. There is no treatment guideline. The majority of patients were treated with corticosteroids and the most common immunososupressant were azathioprine, cyclophosphamide and mycophenolate.
CONCLUSION
Vasculitis and thrombosis may be responsible for severe life-threatening manifestations such as pancreatitis, protein loosing gastroenteritis, acalculous cholecistyitis and enteritis.

Review
INTRODUCTION
Portal vein obstruction (PVO) is a significant vascular complication after liver transplantation (LT) in pediatric patients. Current treatment strategies include percutaneous transluminal angioplasty (PTA), with or without stent placement, mesorex bypass (MRB), splenorenal shunt, mesocaval shunt, endovascular recanalization (EVR), splenic artery embolization and splenectomy. However, specific characteristics of patients undergoing intervention and selection of individual treatment and its efficacy have remained unclear. This review systematically analyzed biochemical and clinical characteristics, selection of treatment, efficacy, and post-procedural complications.
METHODS
We systematically searched PubMed and Embase between January 1995 and March 2021 for studies on the management of PVO after LT. We analyzed the reports for biochemical and clinical characteristics at the timing of the intervention in different patients, selection of treatment, and reported efficacies.
RESULTS
We found 22 cohort studies with 362 patients who had the following characteristics: biliary atresia (83%), living-donor LT (85%), thrombocytopenia (73%), splenomegaly (40%), ascites (16%), or gastrointestinal bleeding (26%). The 3-year primary patency of PTA without stent placement was similar to that with stent placement (70%-80% and 43%-94%, respectively). MRB was used as an initial treatment with a 3-year patency of 75% to 100%. One study showed that 5-year primary patency of EVR was 80%. Secondary patency was 90% to 100% after 3 years in all studies with PTA alone, PTA/stent placement, and stent placement alone.
CONCLUSION
This is the first review of all treatment protocols in PVO after pediatric LT. We showed that an important group of patients has severe symptoms of portal hypertension. Efficacy of all treatment modalities was high in the included studies which make them important modalities for these patients.

Meta-Analysis
The World Health Organization (WHO) introduced the new dengue classification in 2009. We aimed to assess the association of clinical signs and symptoms with WHO severe dengue classification in clinical practice. A systematic literature search was performed using the databases of PubMed, Embase, and Scopus between 2009 and 2018 according to PRISMA guideline. Meta-analysis was performed with the RevMan software. A random or fixed-effect model was applied to pool odds ratios and 95% confidence intervals of important signs and symptoms across studies. Thirty nine articles from 1790 records were included in this review. In our meta-analysis, signs and symptoms associated with higher risk of severe dengue were comorbidity, vomiting, persistent vomiting, abdominal pain or tenderness, pleural effusion, ascites, epistaxis, gum bleeding, GI bleeding, skin bleeding, lethargy or restlessness, hepatomegaly (>2 cm), increased HCT with decreased platelets, shock, dyspnea, impaired consciousness, thrombocytopenia, elevated AST and ALT, gall bladder wall thickening and secondary infection. This review shows new factors comorbidity, epistaxis, GI and skin bleeding, dyspnea, gall bladder wall thickening and secondary infection may be useful to refine the 2009 classification to triage severe dengue patients.
