Table_1_Association between high-density lipoprotein cholesterol and type 2 diabetes mellitus: dual evidence from NHANES database and Mendelian randomization analysis.docx
BackgroundLow levels of high-density lipoprotein cholesterol (HDL-C) are commonly seen in patients with type 2 diabetes mellitus (T2DM). However, it is unclear whether there is an independent or causal link between HDL-C levels and T2DM. This study aims to address this gap by using the The National Health and Nutrition Examination Survey (NHANES) database and Mendelian randomization (MR) analysis.Materials and methodsData from the NHANES survey (2007-2018) with 9,420 participants were analyzed using specialized software. Logistic regression models and restricted cubic splines (RCS) were used to assess the relationship between HDL-C and T2DM incidence, while considering covariates. Genetic variants associated with HDL-C and T2DM were obtained from genome-wide association studies (GWAS), and Mendelian randomization (MR) was used to evaluate the causal relationship between HDL-C and T2DM. Various tests were conducted to assess pleiotropy and outliers.ResultsIn the NHANES study, all groups, except the lowest quartile (Q1: 0.28-1.09 mmol/L], showed a significant association between HDL-C levels and reduced T2DM risk (all P -13), and there was no evidence of pleiotropy or outliers.ConclusionThis study provides evidence supporting a causal relationship between higher HDL-C levels and reduced T2DM risk. Further research is needed to explore interventions targeting HDL-C levels for reducing T2DM risk.</p
Table_1_The association between systemic immune-inflammation index and chronic obstructive pulmonary disease in adults aged 40 years and above in the United States: a cross-sectional study based on the NHANES 2013–2020.docx
BackgroundInflammation is the core of Chronic obstructive pulmonary disease (COPD) development. The systemic immune-inflammation index (SII) is a new biomarker of inflammation. However, it is currently unclear what impact SII has on COPD. This study aims to explore the relationship between SII and COPD.MethodsThis study analyzed patients with COPD aged ≥40 years from the National Health and Nutrition Examination Survey (NHANES) in the United States from 2013 to 2020. Restricted Cubic Spline (RCS) models were employed to investigate the association between Systemic immune-inflammation index (SII) and other inflammatory markers with COPD, including Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR). Additionally, a multivariable weighted logistic regression model was utilized to assess the relationship between SII, NLR and PLR with COPD. To assess the predictive values of SII, NLR, and PLR for COPD prevalence, receiver operating characteristic (ROC) curve analysis was conducted. The area under the ROC curve (AUC) was used to represent their predictive values.ResultsA total of 10,364 participants were included in the cross-sectional analysis, of whom 863 were diagnosed with COPD. RCS models observed non-linear relationships between SII, NLR, and PLR levels with COPD risk. As covariates were systematically adjusted, it was found that only SII, whether treated as a continuous variable or a categorical variable, consistently remained positively associated with COPD risk. Additionally, SII (AUC = 0.589) slightly outperformed NLR (AUC = 0.581) and PLR (AUC = 0.539) in predicting COPD prevalence. Subgroup analyses revealed that the association between SII and COPD risk was stable, with no evidence of interaction.ConclusionSII, as a novel inflammatory biomarker, can be utilized to predict the risk of COPD among adults aged 40 and above in the United States, and it demonstrates superiority compared to NLR and PLR. Furthermore, a non-linear association exists between SII and the increased risk of COPD.</p

Modeling Free Nitrous Acid Inhibition on the Removal of Nitrogen and Atenolol during Sidestream Partial Nitritation Processes
Sidestream serves as an important reservoir collecting
pharmaceuticals
from sludge. However, the knowledge on sidestream pharmaceutical removal
is still insufficient. In this work, atenolol biodegradation during
sidestream partial nitritation (PN) processes characterized by high
free nitrous acid (FNA) accumulation was modeled. To describe the
FNA inhibition on ammonia oxidation and atenolol removal, Vadivelu-type
and Hellinga-type inhibition kinetics were introduced into the model
framework. Four inhibitory parameters along with four biodegradation
kinetic parameters were calibrated and validated separately with eight
sets of batch experimental data and 60 days’ PN reactor operational
data. The developed model could accurately reproduce the dynamics
of nitrogen and atenolol. The model prediction further revealed that
atenolol biodegradation efficiencies by ammonia-oxidizing bacteria
(AOB)-induced cometabolism, AOB-induced metabolism, and heterotrophic
bacteria-induced biodegradation were 0, ∼ 60, and ∼35%
in the absence of ammonium and FNA; ∼ 14, ∼ 29, and
∼28% at 0.03 mg-N L–1 FNA; and 7, 15, and
5% at 0.19 mg-N L–1 FNA. Model simulation showed
that the nitritation efficiency of ∼99% and atenolol removal
efficiency of 57.5% in the PN process could be achieved simultaneously
by controlling pH at 8.5, while 89.2% total nitrogen and 57.1% atenolol
were removed to the maximum at pH of 7.0 in PN coupling with the anammox
process. The pH-based operational strategy to regulate FNA levels
was mathematically demonstrated to be effective for achieving the
simultaneous removal of nitrogen and atenolol in PN-based sidestream
processes
Covalently Assembled Black Phosphorus/Conductive C<sub>3</sub>N<sub>4</sub> Hybrid Material for Flexible Supercapacitors Exhibiting a Superlong 30,000 Cycle Durability
Black phosphorus (BP) has been demonstrated
as a promising electrode
material for supercapacitors. Currently, the main limitation of its
practical application is the low electrical conductivity and poor
structure stability. Hence, BP-based supercapacitors usually severely
suffer from low capacitance and poor cycling stability. Herein, a
chemically bridged BP/conductive g-C3N4 (BP/c-C3N4) hybrid is developed via a facile ball-milling
method. Covalent P–C bonds are generated through the ball-milling
process, effectively preventing the structural distortion of BP induced
by ion transport and diffusion. In addition, the overall electrical
conductivity is significantly enhanced owing to the sufficient coupling
between BP and highly conductive c-C3N4. Moreover,
the imbalanced charge distribution around the C atom can induce the
generation of a local electric field, facilitating the charge transfer
behavior of the electrode material. As a result, the BP/c-C3N4-20:1 flexible supercapacitor (FSC) exhibits an outstanding
volumetric capacitance of 42.1 F/cm3 at 0.005 V/s, a high
energy density of 5.85 mW h/cm3, and a maximum power density
of 15.4 W/cm3. More importantly, the device delivers excellent
cycling stability with no capacitive loss after 30,000 cycles
DataSheet2_Concordance of the treatment patterns for major depressive disorders between the Canadian Network for Mood and Anxiety Treatments (CANMAT) algorithm and real-world practice in China.pdf
Background: Antidepressant (AD) algorithm is an important tool to support treatment decision-making and improve management of major depressive disorder (MDD). However, little is known about its concordance with real-world practice. This study aimed to assess the concordance between the longitudinal treatment patterns and AD algorithm recommended by a clinical practice guideline in China.Methods: Data were obtained from the electronic medical records of Shanghai Mental Health Center (SMHC), one of the largest mental health institutions in China. We examined the concordance between clinical practice and the Canadian Network for Mood and Anxiety Treatments (CANMAT) algorithm among a cohort composed of 19,955 MDD patients. The longitudinal characteristics of treatment regimen and duration were described to identify the specific inconsistencies. Demographics and health utilizations of the algorithm-concordant and -discordant subgroups with optimized treatment were measured separately.Results: The overall proportion of algorithm-concordant treatment significantly increased from 84.45% to 86.03% during the year of 2015–2017. Among the patients who received recommended first-line drugs with subsequent optimized treatment (n = 2977), the concordance proportion was 27.24%. Mirtazapine and trazodone were the most used drugs for adjunctive strategy. Inadequate or extended duration before optimized treatment are common inconsistency. The median length of follow-up for algorithm-concordant (n = 811) and algorithm-discordant patients (n = 2166) were 153 days (Q1-Q3 = 79–328) and 368 days (Q1-Q3 = 181–577) respectively, and the average number of clinical visits per person-year was 13.07 and 13.08 respectively.Conclusion: Gap existed between clinical practice and AD algorithm. Improved access to evidence-based treatment is required, especially for optimized strategies during outpatient follow-up.</p
