BACKGROUND The effectiveness of surgical pleth index (SPI) for managing nociception-antinociception balance during general anesthesia with vasodilators, including nicardipine has not been demonstrated. We aimed to compare the time course during surgery in SPI values in patients receiving nicardipine or remifentanil infusion during thyroidectomy. METHODS Forty patients undergoing thyroidectomy...

Climate change has caused droughts to increase in frequency and severity worldwide, which attracted scientists create drought prediction models mitigate the impacts of droughts. One most important challenges addressing is developing accurate predict their discrete characteristics, i.e., occurrence, duration, severity. The current research examined performance several different machine learning ...

The liver fibrosis index (LFI), based on real‑time tissue elastography (RTE), is a method currently used to assess liver fibrosis. However, this method may not consistently distinguish between the different stages of fibrosis, which limits its accuracy. The aim of the present study was to develop novel models based on biochemical, RTE and ultrasound data for predicting significant liver fibrosi...

Context Isoflavones found in soy products have a chemical structure similar to estrogen, leading to concerns of an adverse estrogenic effect in men, particularly in those with type 2 diabetes mellitus (T2DM) who have low testosterone levels due to hypogonadism. Objective The primary outcome was change in total testosterone levels. The secondary outcomes were the changes in glycemia and cardio...

comparability analyses are performed to investigate similarities/differences of the standard precipitation index (spi) and the reconnaissance drought index (rdi), respectively, utilizing precipitation and ratio of precipitation over potential evapotranspiration (et0). data are from six synoptic stations in south khorasan province in iran.at the first for calculating spi, the elevation-precipita...

[1] The probabilities of the occurrence of extreme dry/wet years and seasons in Europe are estimated by using two ways of the Standardized Precipitation Index (SPI and SPI-GEV) and the Standardized Nonstationary Precipitation Index (SnsPI). The latter is defined as the SPI by fitting precipitation data with a nonstationary Gamma distribution in order to model the precipitation time dependence u...

This study is intended to examine the past drought and predict future drought scenarios for Arkansas-Red River Basin with comprehensive drought indices ranging from meteorology, hydrometeorology to hydrology. In this proceeding, we present some early results and analysis with the Standardized Precipitation Index (SPI) and the Palmer Drought Severity Index (PDSI). Historical climate data within ...

Purpose: Surgical Plethysmographic Index (SPI), calculated from pulse photo-plethysmographic amplitude oscillations, has been proposed as a tool to measure nociception anti-nociception balance during general anaesthesia, but it is affected by several confounding factor that alter the autonomic nervous system (ANS) modulation. We hypotesised that SPI may be mainly affected by sympathetic stimula...
