The 2014 Pancreas Allocation System established national qualifying criteria for simultaneous kidney pancreas (SPK) transplantation. The 2019 UNOS Pancreas Transplantation Committee Policy 11.3.B modified these guidelines to expand transplantation. Subsequent effects on recipient demographics have not been studied. We analyzed 81 SPK transplantations performed at our center from June 2014 to December 2020 to compare recipient demographics and outcomes before and after the 11.3.B policy change. National data were al [...]

YNCRG is a combination of five traditional Chinese ingredients with medicinal properties. We studied its effects and mechanism of action on a rat model of non-alcoholic fatty liver with metabolic syndrome. Eight-week-old male SHRcp rat(s) and Wister Kyoto (WKY) rats were adaptively fed for one week, after which they were randomly divided into three groups, including the control group (n = 9), the YNCRG group (n = 8), and the WKY group (n = 8). The WKY group could freely consume water, the control group was provided [...]

Cholangiocarcinoma is an uncommon adenocarcinoma with poor prognosis. Signet ring cell cholangiocarcinoma is an extremely rare disease, with only 11 cases reported to date. However, its incidence is increasing. Similarly, there is an increasing incidence of other SRC tumors (colon, gastric etc.) as well. Most cases have described a localized mass of signet ring cells, mostly in the common bile duct. A 69-year-old Caucasian man admitted for jaundice and abdominal pain that began 3 days prior to his hospitalization. [...]

This study examines the hydrochemical characteristics of groundwater in the Mutoshi mining environment in Kolwezi, Democratic Republic of Congo, addressing gaps in understanding the impact of mining on water quality. Despite the DRC's vast water resources, only 26% of the urban population has access to safe drinking water, with the Mutoshi aquifer, providing over a quarter of Kolwezi's drinking water, facing deterioration due to underlying copper and cobalt-rich geological formations. Groundwater and geological sam [...]

The geriatric population is increasing all over the world. Aging people have special health requirements and comprehensive medical checkups prevent physical, functional and mental decline during the aging period. This study aimed to examine the fitness level and identify problems with the well-being of elderly persons. In this context, the study also attempted to determine the relationship between socio-demographic factors and the health status of elderly adults. In this cross-sectional study, 168 elderly adults (≥ [...]

Acute pancreatitis (AP) is an inflammatory condition of the pancreas and is one of the most common ailments of the gastrointestinal system that results in significant morbidity and mortality. The main etiologic causes of AP are alcohol consumption, gallstones, hypertriglyceridemia, and biliary stones. The clinical signs and symptoms, and diagnostic criteria of AP are well established in the literature and multiple studies. Multiple scoring systems have been used to predict the severity, prognosis, and mortality a [...]

Because of climate change, greenhouse gas (GHG) emissions have increased, leading to the implementation of energy transition policies. Countries have adopted the Paris Agreement to curb the effects of climate change. The emergence of COVID-19 in 2020 led to the application of different measures to stop its transmission. This study evaluated the effects of COVID-19-related restrictions (such as quarantine and mobility restriction) in Chile during the first wave on compliance with the country's energy transition poli [...]

To increase power level in an autonomous microgrid, higher voltage is necessary. In this paper, detailed Matlab/Simulink modeling of a microgrid operated at medium-voltage level and at constant frequency has been conducted. Modified boost converter and medium-frequency transformer isolated DC/DC converter are adopted for both solar energy and wind energy harnessing in order for them to be connected with the microgrid. This paper further adopted a differential evolution (DE)-based method to carry out load flow analy [...]
