Targeting Microbiota: What Do We Know about It at Present?

Targeting Microbiota: What Do We Know about It at Present? Medicina (Kaunas). 2019 Aug 10;55(8): Authors: Derovs A, Laivacuma S, Krumina A Abstract The human microbiota is a variety of different microorganisms. The composition of microbiota varies from host to host, and it changes during the lifetime. It is known that microbiome may be changed because of a diet, bacteriophages and different processes for example, such as inflammation. Like all other areas of medicine, there is a continuous growth in the area of microbiology. Different microbes can reside in all sites of a human body, even in locations that were previously considered as sterile; for example, liver, pancreas, brain and adipose tissue. Presently one of the etiological factors for liver disease is considered to be pro-inflammatory changes in a host's organism. There are lot of supporting data about intestinal dysbiosis and increased intestinal permeability and its effect on development of liver disease pointing to the gut-liver axis. The gut-liver axis affects pathogenesis of many liver diseases, such as chronic hepatitis B, chronic hepatitis C, alcoholic liver disease, non-alcoholic liver disease, non-alcoholic steatohepatitis, liver cirrhosis and hepatocellular carcinoma. Gut microbiota has been implicated in the regulation of brain health, emphasizing the gut-brain axis. Also, experiments with mice showed that microorganisms have significant effects on the blood-brain barrier integrity. M...

Authors: Yoo JJ, Yu SJ, Lee B, Cho EJ, Lee JH, Kim SG, Kim YJ, Kim YS, Yoon JH Abstract Background/Aims: Patients with an intermediate stage of hepatocellular carcinoma (HCC) represent a highly heterogeneous population; therefore, many models have been proposed to predict the survival of these patients. The aim of this study was to evaluate the prognostic performance of a novel subclassification for tumors classified as Barcelona Clinic Liver Cancer (BCLC) stage B using the Model to Estimate Survival in Ambulatory HCC patients (MESIAH). Methods: This analysis was based on 377 patients with HCC treated at Seoul ...

Conclusions: Chromosomal alterations were frequently identified in both PDAC and IPMN with similar patterns. CEP18 gain and 17p and 18q deletions might be involved in the later stages of PDAC tumorigenesis. Chromosome 17p and 18q deletions might be excellent diagnostic markers.

Conclusions: Initiating IFN-based treatment prompted some deterioration in general and HCV-related HRQoL, accompanied by impaired daily activities and most work productivity measures; however, the HRQoL and productivity scores improved towards the EOT. HRQoL impairment upon treatment initiation likely contributed to treatment discontinuation. PMID: 31533395 [PubMed - as supplied by publisher]

"Gut Microbiota-Circadian Clock Axis" in Deciphering the Mechanism Linking Early-Life Nutritional Environment and Abnormal Glucose Metabolism. Int J Endocrinol. 2019;2019:5893028 Authors: Zhou L, Kang L, Xiao X, Jia L, Zhang Q, Deng M Abstract The prevalence of diabetes mellitus (DM) has been increasing dramatically worldwide, but the pathogenesis is still unknown. A growing amount of evidence suggests that an abnormal developmental environment in early life increases the risk of developing metabolic diseases in adult life, which is referred to as the "metabolic memory" and the Deve...

Authors: Nakamura H, Utsunomiya A, Ishida Y, Horita T Abstract A 48-year-old man was brought to our emergency room with acute abdominal pain and systemic edema, indicating acute circulatory failure with lactic acidosis. Furosemide treatment paradoxically worsened the systemic edema and induced confusion. He had no drinking history but hardly ate legumes or meats containing thiamine. Administration of fursultiamine dramatically improved the symptoms and subsequently caused pulmonary edema. Thiamine deficiency may occur in nondrinkers with an unbalanced diet. In this condition, diuretic therapy can worsen the symptom...

Conclusion The present study showed that high plasma glucose levels and severe liver fibrosis stage influence insulin secretion levels in Japanese patients with NAFLD. Conservation of delayed insulin secretion levels was confirmed in patients with severe liver fibrosis. PMID: 31534089 [PubMed - as supplied by publisher]

Conclusion The rate of subjects who underwent HCV screening and DAA treatment was not high, especially in the younger generation, in Saga Prefecture. This group should be targeted for HCV screening and treatment. PMID: 31534084 [PubMed - as supplied by publisher]

ConclusionsEGCG can be used for cancer treatment. It increases the potency of several chemotherapeutics such as doxorubicin, cisplatin, and tamoxifen, in vivo and in vitro, in many cancers. MDR reversal by EGCG is facilitated by a plethora of mechanisms including oxidative and antioxidative responses, altered cell death and survival responses, suppression of oncogenic transcription factors, modulating the tumor microenvironment, and regulating multiple signal transduction pathways.

Background: Hepatocellular carcinoma (HCC) accounts for 90% of primary hepatic malignancies. With the exception of chronic hepatitis B (CHB), other etiologies of chronic liver disease require progression to cirrhosis before HCC development. Case reports have described HCC in noncirrhotic patients with hepatitis C (HCV) and nonalcoholic fatty liver disease. Goal: The aim of this study was to determine the prevalence of patients without cirrhosis and CHB who developed HCC among a large cohort of HCC patients and to identify independent variables that are associated with no cirrhosis among patients with HCC. Study: Fr...

Conclusions: Although overall rates of initial HCC screening among cirrhosis patients is nearly 75%, retention into continued HCC surveillance is poor, with less than half of patients undergoing subsequent HCC surveillance. Cirrhosis patients with HBV and NASH were more likely to be retained into HCC surveillance.
