BACKGROUND: New criteria for acute kidney injury (AKI) in cirrhosis have been proposed, but its prognostic significance is unclear. This study aims to evaluate the prognostic significance of the AKI criteria in cirrhotic patients hospitalized for acute decompensation. MATERIAL AND METHODS: This is a prospective cohort study. AKI was defined as an increase in creatinine (Cr) levels ≥ 0.3 mg/dL in 48 h or ≥ 50% of the basal value in the last 7d. AKI was divided into stages 1 (elevation: < 2x basal), 2 (2 or 3x), and 3 (> 3x)...

Background: Colorectal surgery in cirrhotic patients has had limited indications, but as the study aims to show, careful evaluation of risk factors can extend boundaries. Methods: From January 2011 to January 2016, using a case match cohort, 68 patients with colorectal malignancy and cirrhosis were compared against 136 persons with no liver disease. Significant risk criteria, morbidity and mortality were evaluated. Results: When analyzing specific risk factors age, etiology and severity of liver disease (MELD, Child-Pugh score, ascites and hypoalbuminemia) were found to be significant to surgical outcome...

Indian childhood cirrhosis is an entity believed to be on the verge of extinction. We present the case of a 13-month-old girl presenting acutely with jaundice, fever, and persistently increasing bilirubin. Investigations revealed direct hyperbilirubinemia, elevated transaminases, anemia, a blood with few schistocytes, positive direct coombs test, and deranged prothrombin time. Viral, autoimmune, and metabolic workup was unremarkable. Ultrasonography showed chronic liver disease, portal hypertension, and ascites...

Acute on chronic liver failure (ACLF) is a culmination of chronic liver disease and extra-hepatic organ failures, which is associated with a high short-term mortality and immense healthcare expenditure. There are varying definitions for organ failures and ACLF in Europe, North America and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multi-factorial and related to interactions between the immuno-inflammatory system, microbiota and the precipitating factors...

A 48-year-old woman with alcoholic liver cirrhosis was admitted to our hospital because of hematochezia and severe anemia. She had been hospitalized many times over the past year for hematochezia of unknown etiology. Contrast-enhanced CT demonstrated ileal varices, which were fed by several ileal veins. These feeding veins were selectively embolized with N-butyl cyanoacrylate (NBCA) via a recanalized paraumbilical vein. The paraumbilical vein instead of the portal vein was punctured to decrease the risk of bleeding complications because she had coagulopathy and ascites...

Chemotherapeutic resistance evolves in about 70 % of ovarian cancer patients and is a major cause of death in this tumor entity. Novel approaches to overcome these therapeutic limitations are therefore highly warranted. A disintegrin and metalloprotease 17 (ADAM17) is highly expressed in ovarian cancer and required for releasing epidermal growth factor receptor (EGFR) ligands like amphiregulin (AREG). This factor has recently been detected in ascites of advanced stage ovarian cancer patients. However, it is not well understood, whether and how ADAM17 might contribute to chemo resistance of ovarian cancer...

BACKGROUND: Chylopericardium effusion is characterized by the accumulation of milky effusion in the pericardium. It is often idiopathic but it can be secondary to trauma, chest radiation, tuberculosis and malignancy. If cardiac tamponade ensues, it becomes life-threatening. Herein we describe chylopericardium tamponade in a child with IgA nephropathy. To the best of our knowledge, this is the first reported case of chylopericardium tamponade in IgA nephropathy. CASE PRESENTATION: A 6 years old boy with IgA nephropathy presented with dyspnea, orthopnea, pretibial pitting edema, ascites and fever...

Photodynamic therapy (PDT) is considered as an innovative and attractive modality to treat ovarian cancer. In this study, a biodegradable polymer poly (ethylene glycol)-poly (lactic acid)(PLA)-folate (FA-PEG-PLA) was prepared in order to synthesize an active targeting, water soluble and pharmacomodulated photosensitizer nano-carriers. The drug loading content, encapsulation efficiency, in vitro and in vivo release were characterized, in which HB/FA-PEG-PLA micelles had a high encapsulation efficiency and much slower control release for drugs compared to free drugs (p<0...

Peritoneal dialysis (PD) performed with transmembrane pH-gradient liposomes was reported to efficiently remove ammonia from the body, representing a promising alternative to current standard-of-care for patients with severe hepatic encephalopathy. In this study, we further characterized the properties of liposome-supported peritoneal dialysis (LSPD) by 1) assessing its in-use stability in the presence of ascitic fluids from liver-disease patients; 2) investigating its interactions with drugs that are commonly administered to acute-on-chronic liver failure patients; and 3) analyzing the in vivo extraction profile of LSPD...

We describe the case of a previously 77-year-old man who accessed in our Nephrology Unit for acute kidney injury (AKI) on chronic kidney disease (CKD), gastric discomfort and vague urinary symptoms with apparently preserved diuresis and suspected "ascites". Physical examination confirmed the presence of abdominal effusion, even though ultrasound abdominal examination revealed the presence of a giant diverticular urinary bladder with bilateral hydronephrosis. We discuss the diagnostic and therapeutic approach of these rare complications by briefly reviewing the technical aspects and the possible consequences...

BACKGROUND: Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes that play a key role in preventing chromosomal instability. The aim of the present study is to determine telomere length using fluorescence in situ hybridisation (FISH) on cytological specimens. METHODS: Aspiration samples (n = 41) were smeared on glass slides and used for FISH. RESULTS: Telomere signal intensity was significantly lower in positive cases (cases with malignancy, n = 25) as compared to negative cases (cases without malignancy, n = 16), and the same was observed for centromere intensity...

Although adoptive cell therapy (ACT) has demonstrated effective and remarkable clinical responses in several studies, this approach does not lead to objective clinical responses in all cases. The function of ACT is often compromised by various tumor escape mechanisms, including the accumulation of immunoregulatory cells. As a result of peritoneal metastasis in the terminal stage, malignant ascites fluid lacks effectiveness and is a poor prognostic factor for gastric cancer. The present study assessed T-cell subsets in lymphocytes derived from malignant ascites, and investigated the effects of arsenic trioxide (As2 O3 ) on regulatory T cells (Tregs) and ascites-derived tumor-infiltrating lymphocytes (TILs) in vitro ...

Improved in vitro models are needed to better understand cancer progression and bridge the gap between in vitro proof-of-concept studies, in vivo validation, and clinical application. Multicellular tumor spheroids (MCTS) are a popular method for three-dimensional (3D) cell culture, because they capture some aspects of the dimensionality, cell-cell contact, and cell-matrix interactions seen in vivo. Many approaches exist to create MCTS from cell lines, and they have been used to study tumor cell invasion, growth, and how cells respond to drugs in physiologically relevant 3D microenvironments...
