Intra-Abdominal Hypertension and Abdominal Compartment Syndrome in Liver Diseases

Intra-abdominal hypertension (IAH) is defined as an intra-abdominal pressure (IAP) above 12 mmHg. Abdominal compartment syndrome (ACS) is defined as an IAP above 20 mmHg with evidence of organ failure. Moreover, IAH/ACS is a condition that can cause acute renal failure, respiratory failure, circulatory disease, gastrointestinal dysfunction, and liver failure due to elevated IAP. The incidence of IAH/ACS increases in the more critically ill patient and is associated with significantly increased morbidity and mortality. Ascites, blood, or tumors increase IAP. In liver cirrhosis, massive ascites is often encountered. Hence, preventing IAH/ACS conditions may improve outcomes of patients with liver disease

Aligning cellular and molecular components in age-dependent tertiary lymphoid tissues of kidney and liver

Tertiary lymphoid tissues (TLTs) are ectopic lymphoid structures induced by multiple stimuli, including infection and tissue injuries; however, their clinical relevance in disease progression has remained unclear. We demonstrated previously that TLTs develop in mouse and human kidneys with aging and can be a potential marker of kidney injury and prognosis, and therapeutic targets. In addition, we found that two types of unique lymphocytes that emerge with aging, senescence-associated T cells and age-associated B cells, are essential for TLT formation in the kidney. Although TLTs develop with aging in other organs as well, their cellular and molecular components, and clinical significance remain unclear. In the present study, we found that TLTs developed in the liver with aging, and that their cellular and molecular components were similar to those in the kidneys. Notably, senescence-associated T cells and age-associated B cells were also present in hepatic TLTs. Furthermore, analysis of publicly available data on human liver biopsy transcriptomes revealed that the expression of TLT-related genes was elevated in the liver biopsy samples from hepatitis C virus (HCV)-infected patients compared with those without HCV infection and was associated with liver injury and fibrosis. Therefore, we analyzed liver biopsy samples from 47 HCV patients and found that TLTs were present in 87.2% of cases and that the numbers and stages of TLTs were higher in aged patients and cellular and molecular components of TLTs in humans were similar to those in mice. Our findings suggesting that age-dependent TLT formation is a systemic phenomenon across the tissues and aging is also a predisposing factor for TLT formation across organs

Cross-Cultural Comparison of Organizational Structure in a Multinational Organizational Environment

Due to globalization, cross-cultural specifics exploration is of crucial importance for the success of businesses in opening and maintaining new markets. Whilst cultural differences are more obvious and remarkable than similarities and homogeneities, they must be taken into account in management practices being of high importance for understanding organizational behavior. This study investigates the extent to which relationships between context and structure are stable across cultures, it also examines if cultural differences between nations account for variations in their suggested desired structure. The study first analyzes the structure of sample companies and then compares the findings with data on matched analogue companies. The cross-cultural comparison between the resulting structure revealed that a resultant personnel bureaucracy structure for fitted well their high concentration of authority and low structuring of activities, but it did not match the desired full bureaucracy. In response to the analysis of the results obtained, new research directions on the influence of cultural differences and their application in global businesses were identified

Successful treatment of positive-sense RNA virus coinfection with autoimmune hepatitis using double filtration plasmapheresis

Double filtration plasmapheresis (DFPP) is an apheretic technique that selectively removes high molecular weight substances using a plasma component filter. DFPP has been used to treat positive-sense RNA virus infections, mainly chronic hepatitis C virus (HCV) infection, because of its ability to directly eliminate viral particles from blood plasma from 2008 to about 2015, before direct-acting antiviral agents was marketed. This effect has been termed virus removal and eradication by DFPP. HCV is a positive-sense RNA virus similar to West Nile virus, dengue virus and the SARS and Middle East respiratory syndrome coronaviruses. SARS-CoV-2 is classified same viral species. These viruses are all classified in Family Flaviviridae which are family of single-stranded plus-stranded RNA viruses. Viral particles are 40–60 nm in diameter, enveloped and spherical in shape. We present a rare case of HCV removal where an RNA virus infection that copresented with virus-associated autoimmune hepatitis was eliminated using DFPP. Our results indicate that DFPP may facilitate prompt viraemia reduction and may have novel treatment applications for SARS-CoV-2, that is, use of therapeutic plasma exchange for fulminant COVID-19.</jats:p

Rare paraneoplastic syndromes in digestive systems caused by lung cancer

We observed a rare case of two different digestive paraneoplastic syndromes that improved with the treatment of the neoplasms. The first syndrome was chronic intestinal pseudo-obstruction (CIPO), which is a subtype of paraneoplastic syndromes called a paraneoplastic neurological syndrome (PNS). The second was Stauffer’s syndrome, which is a unique paraneoplastic syndrome characterised by non-metastatic intrahepatic cholestasis associated with neoplasms. Here, we report the case of a 55-year-old man who presented with two concurrent paraneoplastic syndromes in the digestive system. The intestinal pseudo-obstruction and elevated biliary enzyme levels improved as the lung cancer responded to chemotherapy. In this case, CIPO as a PNS led to the detection of lung cancer. To our knowledge, this is the first report of Stauffer’s syndrome caused by lung adenocarcinoma.</jats:p
