Association of Sex With Cardiovascular Outcomes in Heart Failure Patients With Obstructive or Central Sleep Apnea.

Background: This study investigated the association of sex with cardiovascular outcomes in a prospective cohort of patients with heart failure (HF) with obstructive sleep apnea or central sleep apnea.

Methods And Results: Patients were screened for sleep apnea on admission using multichannel cardiopulmonary monitoring from May 2015 to July 2018. The primary outcome was a composite of cardiovascular death or unplanned hospitalization for worsening HF.

Prediction of effluent total nitrogen and energy consumption in wastewater treatment plants: Bayesian optimization machine learning methods.

The control of effluent total nitrogen (TN) and total energy consumption (TEC) is a key issue in managing wastewater treatment plants. In this study, effluent TN and TEC predictive models were established by selecting influent water quality and process control indicators as input features. The prediction performance of machine learning methods under different random seeds was explored, the moving average method was used for data amplification, and the Bayesian algorithm was used for hyperparameter optimization.

Association of hypoxic burden metrics with cardiovascular outcomes in heart failure and sleep-disordered breathing.

Aims: Heart failure (HF) and sleep-disordered breathing (SDB) frequently coexist. We aimed to compare the prognostic value of different nocturnal hypoxic burden metrics in hospitalized HF patients.

Methods And Results: HF patients underwent polygraphy screening for SDB in this prospective cohort.

Prevalence, clinical characteristics, and predictors of sleep disordered breathing in hospitalized heart failure patients.

Background: Heart failure (HF) is often comorbid with sleep disordered breathing (SDB). This prospective study investigated the prevalence, clinical characteristics, and predictors of SDB in hospitalized HF patients.

Methods: Sleep studies were performed on hospitalized HF patients from January 2015 to February 2019.

Prediction of all-cause mortality with malnutrition assessed by nutritional screening and assessment tools in patients with heart failure：a systematic review.

Background And Aims: In the absence of a gold standard or scientific consensus regarding the nutritional evaluation of heart failure (HF) patients, this study aimed to summarize and systematically evaluate the prognostic value of nutritional screening and assessment tools used for all-cause mortality in HF patients.

Methods And Results: Relevant studies were retrieved from major databases (PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), WanFang Data, and China Biology Medicine disc (CMB)) and searched from the earliest available date until July 2021. If three or more studies used the same tool, meta-analysis using RevMan 5.

Prognostic value of sleep apnea and nocturnal hypoxemia in patients with decompensated heart failure.

Background: Nocturnal hypoxemia is an important factor underlying the impact of sleep apnea on heart failure. It remains unclear whether nocturnal hypoxemia has a greater prognostic value in acute decompensated heart failure (ADHF) compared with the frequency of sleep apnea.

Hypothesis: Nocturnal hypoxemia might be better than the frequency of sleep apnea in predicting the outcomes in ADHF.

[Enhanced Treatment of Printing and Dyeing Wastewater Using HO-Biochemical Method].

The traditional biochemical treatment of printing and dyeing wastewater has limited efficiency. This study investigated whether HO could strengthen the biological ability of the hydrolytic acidification/biological contact oxidation process (A/O), which effectively treats the printing and dyeing wastewater. After biofilm formation and the biochemical system startup and operation by HO, the system was successfully started and steadily operated when HOwas added into reactor A with the HO voluve fraction of 3 mL·L, doses of 100.

[Fast Start-up and Performance of the CANON Process Based on a SBAF Systemand Evolution Properties of Microorganisms].

The CANON process has the disadvantages of long start-up periods and unstable operation. In the SBAF system, under strictly controlled conditions of dissolved oxygen (DO) and temperature, a CANON process is started up in 51 days and is operated stably for 278 days using a new method of independent research and development. The results show that the maximum and average ARR are 98.

[Fast Start-up of SBAF System Assisted CANON Process and the Microbial Analysis].

Long period start-up is one of the main restraining factors of the single-stage completely autotrophic nitrogen removal over nitrite (CANON) process.This study investigated the fast start-up of the CANON process initiated by a submerged biological aerated filter (SBAF) method.With conventional activated sludge from the secondary sedimentation tank of municipal waste water treatment plants as the seed sludge,the CANON process was successfully started up after the acclimation of sludge microorganisms for 48 days under the experimental conditions of (30±2)℃,organic carbon free and controlled dissolved oxygen (stage Ⅰ:0.

[Plasma amino-terminal pro-brain natriuretic peptide level and affecting factors in a community-based healthy Chinese population].

Objective: To investigate the plasma level of amino-terminal pro-brain natriuretic peptide (NT-proBNP) and related influencing factors in a community-based healthy population in Beijing area.

Methods: We measured plasma NT-proBNP level by fluoroimmunoassay between March 2012 and July 2012 from 1 034 healthy subjects (including 486 men and 548 women). Empiric method was used to determine the reference value and influencing factors were analyzed.

Methods: Using a cross-sectional research design, CHF patients (n = 267, mean age (63.8 ± 9.

[Predict value of soluble ST2 on one-year mortality for hospitalized patients with chronic heart failure].

Objective: To explore the predict value of plasma soluble ST2 (sST2) on one-year mortality for hospitalized patients with chronic heart failure (HF).

Methods: A total of 1 244 consecutive hospitalized patients admitted to Heart Failure Center Fuwai Hospital between March 2009 and July 2012 and with HF as their primary diagnosis were included.
