The furosemide stress test predicts the timing of continuous renal replacement therapy initiation in critically ill patients with acute kidney injury: a double-blind prospective intervention cohort study.

Background: Continuous renal replacement therapy (CRRT) remains a crucial treatment for critically ill patients with acute kidney injury (AKI), although the timing of its initiation is still a matter of contention. Furosemide stress testing (FST) may be a practical and beneficial prediction instrument. This research was meant to examine if FST can be used to identify high-risk patients for CRRT.

Effect of goal-directed fluid therapy on renal function in critically ill patients: a systematic review and meta-analysis.

Objective: To evaluate whether goal-directed fluid therapy (GDFT) reduces the risk of renal injury in critical illness.

Methods: MEDLINE PubMed, EMBASE, CENTRAL and CBM was searched from inception to 13 March 2022, for studies comparing the effect of GDFT with usual care on renal function in critically ill patients. GDFT was defined as a protocolized intervention based on hemodynamic and/or oxygen delivery parameters.

Harmful algal blooms significantly reduce the resource use efficiency in a coastal plankton community.

Harmful algal blooms (HABs) have been investigated for their catastrophic effects on public health and aquaculture intensively, but the research about HABs effects on the diversity patterns and intrinsic functions of the plankton community based on a species identification with high resolution and accuracy has been scarce. We therefore investigated the shifts of plankton diversity via pyrosequencing during and around a natural dinoflagellate (Prorocentrum donghaiense) bloom and analyzed the effect of P. donghaiense abundance on the operationally-defined resource use efficiency (RUE) of plankton community to test our hypothesis that outbreaks of HABs will reduce RUE of the plankton community via shifting the plankton community structure, species composition in particular.

Cultivation of seaweed Gracilaria lemaneiformis enhanced biodiversity in a eukaryotic plankton community as revealed via metagenomic analyses.

Plankton diversity reflects the quality and health of waters and should be monitored as a critical feature of marine ecosystems. This study applied a pair of 28S rRNA gene-specific primers and pyrosequencing to assess the effects of large-scale cultivation of the seaweed Gracilaria lemaneiformis on the biodiversity of eukaryotic plankton community in the coastal water of Guangdong, China. With 1 million sequences (2,221 operational taxonomic units [OTUs]) obtained from 51 samples, we found that the biodiversity of eukaryotic plankton community was significantly higher in the seaweed cultivation area than that in the nearby control area as reflected in OTU richness, evenness (Shannon-Wiener index) and dominance (Simpson index) for total plankton community and its four subcategories when Gracilaria biomass reached the maximum, while no such a significant difference was observed before seaweed inoculation.

[Comparison of the effect of fluid resuscitation as guided either by lactate clearance rate or by central venous oxygen saturation in patients with sepsis].

Objective: To compare the efficacy of fluid resuscitation as guided by lactate clearance rate (LCR) and central venous oxygen saturation (ScvO2) in patients with sepsis.

Methods: A prospective randomized control study was conducted. Fifty patients diagnosed with severe sepsis or septic shock from January 2011 to February 2012 in department of critical care medicine of Fourth Hospital of Hebei Medical University were enrolled in the study.

[Relationship between tumor necrosis factor beta gene polymorphism and acute respiratory distress syndrome after operation for esophageal carcinoma].

Background And Objective: A single nucleotide polymorphism of the tumor necrosis factor beta (TNF-beta) gene affected the level of tumor necrosis factor beta and was associated with prognosis of acute respiratory distress syndrome (ARDS). This study was to investigate the association between the TNF-beta and ARDS after operation for esophageal carcinoma.

Methods: Thirty-four patients with and 116 patients without ARDS after radical resection for thoracotomic esophageal carcinoma were recruited in the Fourth Hospital of Hebei Medical University from January 2005 to June 2007.

[Correlations of preoperative pulmonary function tests for esophageal cancer to postoperative acute respiratory distress syndrome].

Background & Objective: Acute respiratory distress syndrome (ARDS), a serious postoperative complication of esophageal cancer, has a high mortality rate. Preoperative pulmonary function affects treatment project selection and prognosis prediction. The correlation of preoperative pulmonary function of esophageal cancer to postoperative ARDS has seldom been reported.
