Coronary revascularisation in patients with chronic kidney disease and end-stage renal disease: A meta-analysis.

Int J Clin Pract 2021 Jun 12:e14506. Epub 2021 Jun 12.

Department of Cardiac Surgery, Peking University First Hospital, Beijing, China.

Objectives: To compare coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for revascularising coronary arteries in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). CKD is described as a continuous decrease in the glomerular filtration rate or abnormalities in kidney structure or function.

Methods: PubMed, Cochrane Library and Embase databases were searched for studies on the revascularisation of coronary arteries in patients with CKD and ESRD.

Results: Since no randomised controlled trials (RCTs) have addressed this issue so far, 31 observational studies involving 74 805 patients were included in this meta-analysis. Compared with PCI, patients undergoing CABG have significantly higher early mortality (CKD: RR = 1.62, 95% CI: 1.17-2.25, pheterogeneity = 0.476, I  = 0; ESRD: RR = 1.99, 95% CI: 1.46-2.71, pheterogeneity = 0.001, I  = 66.9%). Patients with ESRD undergoing CABG have significantly lower all-cause mortality (RR = 0.95, 95% CI: 0.93-0.96, pheterogeneity < 0.001, I  = 82.9%) and cardiac mortality (RR = 0.73, 95% CI: 0.58-0.92, pheterogeneity = 0.908, I  = 0). The long-term risk of repeat revascularisation (CKD: RR = 0.24, 95% CI: 0.19-0.30, pheterogeneity = 0.489, I  = 0; ESRD: RR = 0.23, 95% CI: 0.15-0.34, pheterogeneity = 0.012, I  = 54.4%) and myocardial infarction (CKD: RR = .57, 95% CI: 0.38-0.85, pheterogeneity = 0.025, I  = 49.9%; ESRD: RR = 0.42, 95% CI: 0.40-0.44, pheterogeneity = 0.49, I  = 0) remained significantly higher in the PCI group.

Conclusions: Patients with ESRD, but not CKD, who underwent CABG had significantly lower all-cause mortality and cardiac mortality. However, CABG was associated with an increased risk of early mortality in patients with CKD or ESRD. Adequately powered, contemporary, prospective RCTs are needed to define the optimal revascularisation strategy for patients with CKD and ESRD.

Preparation, characterization, and efficient chromium (VI) adsorption of phosphoric acid activated carbon from furfural residue: an industrial waste.

Water Sci Technol 2020 Dec;82(12):2864-2876

Key Laboratory of Low Carbon Energy and Chemical Engineering, College of Chemistry and Bioengineering, Shandong University of Science and Technology, Qingdao, 277590, China E-mail: State Key Laboratory of Heavy Oil Processing, China University of Petroleum (East China), Qingdao 266580, China.

Furfural residue (FR) is an inevitable by-product of industrial furfural production. If FR is not managed properly, it will result in environmental problems. In this study, FR was used as a novel precursor for activated carbon (AC) production by HPO activation under different conditions. Under optimum conditions, the prepared FRAC had high BET surface area (1,316.7 m/g) and micro-mesoporous structures. The prepared FRAC was then used for the adsorption of Cr(VI). The effect of solution pH, contact time, initial Cr(VI) concentration, and temperature was systematically studied. Characterization of the adsorption process indicated that the experimental data were well-fitted by the Langmuir isotherm model and pseudo-second-order kinetics model. The maximum adsorption capacity of 454.6 mg/g was achieved at pH 2.0, which was highly comparable to the other ACs reported in the literatures. The preparation of FRAC using HPO activation can make use of FR's characteristic acidity, which could make it preferable in practical industrial production.

Influence of chronic kidney disease on early clinical outcomes after off-pump coronary artery bypass grafting.

J Cardiothorac Surg 2020 Jul 29;15(1):199. Epub 2020 Jul 29.

Department of Cardiac Surgery, Peking University First Hospital, 8 Xishiku Street, Beijing, 100034, People's Republic of China.

Background: Patients with chronic kidney disease (CKD) have a high incidence of coronary heart disease, which is the leading cause of death in these patients. Coronary artery bypass grafting (CABG) significantly increases short-term mortality and decreases long-term mortality in patients with CKD compared with percutaneous coronary intervention (PCI). The effect of CKD on the early outcomes of off-pump CABG is not well-studied. We aimed to investigate the effect of CKD on early postoperative mortality and complications following off-pump CABG.

Methods: We retrospectively analyzed preoperative baseline and surgery data for 1173 patients undergoing off-pump CABG from January 2010 to December 2017 in the Department of Cardiac Surgery, Peking University First Hospital. Outpatient follow-up was performed until 30 days postoperatively. Patients with estimated glomerular filtration rates calculated according to the Chronic Kidney Disease Epidemiology Collaboration equation of ≥60 mL/min/1.73 m were assigned to the normal renal function group (normal group, n = 924), and those with a rate < 60 mL/min/1.73 m were assigned to the CKD group (CKD group, n = 249).

Results: Patients in the CKD group were seriously ill with multiple complications, and postoperative 30-day mortality and complication rates were significantly higher than those in the normal group. In the logistic regression analysis, after correcting for common confounding factors, namely sex, age, and left ventricular ejection fraction, preoperative CKD was a risk factor for postoperative acute kidney injury, perioperative myocardial infarction, gastrointestinal bleeding, secondary tracheal intubation, stroke, chest wound infection, prolonged mechanical ventilation (≥ 24 h), prolonged intensive care unit stay (≥ 72 h), prolonged length of stay (≥ 14 d), dialysis requirement, and postoperative death within 30 days.

Conclusions: Patients with CKD had more preoperative complications, and their postoperative 30-day mortality and complication rates after off-pump CABG were significantly higher than those of patients with normal renal function. For CABG patients with CKD, the risk of surgery should be assessed carefully, and comprehensive measures should be taken to strengthen perioperative management, with an aim to reduce complications and mortality and improve surgical outcomes.

Crystallization and preliminary X-ray diffraction analysis of UspE from Escherichia coli.

Acta Crystallogr F Struct Biol Commun 2014 Dec 14;70(Pt 12):1640-2. Epub 2014 Nov 14.

Universal stress proteins (Usps) are among the most highly induced genes when bacteria are subjected to several stress conditions such as heat shock, nutrient starvation or the presence of oxidants or other stress agents. Escherichia coli has five small Usps and one tandem-type Usp. UspE (or YdaA) is the tandem-type Usp and consists of two Usp domains arranged in tandem. To date, the structure of UspE remains to be elucidated. To contribute to the molecular understanding of the function of the tandem-type UspE, UspE from E. coli was overexpressed and the recombinant protein was purified using Ni-NTA affinity, Q anion-exchange and gel-filtration chromatography. Crystals of UspE were obtained by sitting-drop vapour diffusion. A diffraction data set was collected to a resolution of 3.2 Å from flash-cooled crystals. The crystals belonged to the tetragonal space group I4122 or I4322, with unit-cell parameters a = b = 121.1, c = 241.7 Å.
