The neutrophil-to-lymphocyte ratio is associated with all-cause and cardiovascular mortality among individuals with hypertension.

BACKGROUND: Identifying reliable prognostic markers is crucial for the effective management of hypertension. The neutrophil-to-lymphocyte ratio (NLR) has emerged as a potential inflammatory marker linked to cardiovascular outcomes. This study aims to investigate the association of NLR with all-cause and cardiovascular mortality among patients with hypertension. METHODS: This study analyzed data from 3067 hypertensive adults in the National Health and Nutritional Examination Surveys (NHANES) from 2009 to 2014. Mortality details were obtained from the National Death Index (NDI). Restricted cubic spline (RCS) was deployed to visualize the association of the NLR with mortality risk. Weighted Cox proportional hazards models were employed to assess the independent association of NLR with mortality risk. Time-dependent receiver operating characteristic curve (ROC) analysis was conducted to access the predictive ability of NLR for survival. Mediation analysis was used to explore the indirect impact of NLR on mortality mediated through eGFR. RESULTS: Over a median 92.0-months follow-up, 538 deaths occurred, including 114 cardiovascular deaths. RCS analysis revealed a positive association between NLR and both all-cause and cardiovascular mortality. Participants were stratified into higher (> 3.5) and lower (≤ 3.5) NLR groups. Weighted Cox proportional hazards models demonstrated that individuals with higher NLR had a significantly increased risk of all-cause (HR 1.96, 95% confidence interval (CI) 1.52-2.52, p < 0.0001) and cardiovascular mortality (HR 2.33, 95% CI 1.54-3.51, p < 0.0001). Stratified and interaction analysis confirmed the stability of the core results. Notably, eGFR partially mediated the association between NLR and both all-cause and cardiovascular mortality by a 5.4% and 4.7% proportion, respectively. Additionally, the areas under the curve (AUC) of the 3-, 5- and 10- year survival was 0.68, 0.65 and 0.64 for all-cause mortality and 0.68, 0.70 and 0.69 for cardiovascular mortality, respectively. CONCLUSION: Elevated NLR independently confers an increased risk for both all-cause and cardiovascular mortality in individuals with hypertension.

Prevalence of self-reported thyroid disease among adults with depression.

BACKGROUND: Thyroid disorders are a common comorbidity in patients with depression, yet there is limited information available about the clinical epidemiology of thyroid diseases in this specific population. This study aims to describe the prevalence of thyroid disease among US adults with depression from 2007 to 2018. METHODS: This cross-sectional study used nationally representative data collected through the National Health and Nutrition Examination Survey (NHANES) between January 1, 2007, to December 31, 2018. Age-standardized prevalence of thyroid disease among depressed patients was calculated within 4-year survey periods (2007-2010, 2011-2014, and 2015-2018), and adjusted to the 2000 U.S. standard population. RESULTS: In our weighed sample, 6.1% of depressed individuals and 4.3% of non-depressed individuals reported thyroid disease between 2007 and 2018 (P < 0.0001). The age-standardized prevalence of thyroid disease in patients with depression increased over time, from 5.4% (95%CI, 4.6%-6.2%) in 2007-2010 to 6.8% (95%CI, 5.8%-8.0%) in 2015-2018 (P for trend = 0.0270). Furthermore, thyroid disease prevalence was highest in non-Hispanic white individuals, increased with age, and tended to be higher in women. Mean depression scores in patients with thyroid disease (9.1; 95%CI, 8.7-9.5) did not significantly different from those without thyroid disease (9.1; 95%CI, 9.0-9.3) (P = 0.96). CONCLUSION: The age-standardized prevalence of thyroid disease among US adults with depression exhibited a consistent increase from 2007 to 2018, with the highest rate occurring in older, non-Hispanic white individuals, and women.

Prevalence and Trends of Thyroid Disease Among Adults, 1999-2018.

BACKGROUND: Thyroid disease is a prominent endocrine disorder, yet the clinical epidemiology of this condition remains unclear. This study aims to describe the recent trends in the prevalence of thyroid disease in US adults from 1999-2018. METHODS: This cross-sectional study used nationally representative data collected through the National Health and Nutrition Examination Survey (NHANES) from January 1, 1999 to December 31, 2018. Patients with thyroid disease were defined as patients who reported having a thyroid disease and were on thyroid-related treatment. Age-standardized prevalence of thyroid disease was calculated within 4-year survey periods (1999-2002, 2003-2006, 2007-2010, 2011-2014, and 2015-2018). RESULTS: During the NHANES 1999-2018, a total of 57 540 participants were examined. The age-standardized prevalence of thyroid disease was 5.05% (95% CI, 4.55%-5.60%) from 2015-2018, signifying a significant increase from the 1999-2002 period (P <.0002). However, prevalent thyroid disease remained steady between 2003 and 2014. The highest prevalence of thyroid disease was observed in non-Hispanic Whites (8.1%; 95% CI, 7.3%-9.0%), individuals aged ≥60 years (15.4%; 95% CI, 13.3%-17.8%), and tended to be higher in women (7.6%; 95% CI, 6.8%-8.5%). Multiple regression analysis revealed that age, women sex, non-Hispanic White and Mexican American, body mass index, higher education and incomes were independently associated with increased risks of thyroid disease. CONCLUSION: The age-standardized prevalence of thyroid disease among US adults increased from 1999-2003, remained stable between 2003 and 2014, and then saw an increase from 2014-2018, with the highest rate observed among elders, women, and non-Hispanic Whites.

Precise Regulation of Combustion Characteristics of High-Energy Composite Propellants by Incorporation of CL-20 Crystals Intercalated with Energetic Burn Rate Modifiers.

In this study, a 2D structured triaminoguanidine-glyoxal polymer with a high nitrogen content has been coordinated with metal ions to produce energetic metal complexes (TAGP-Ms) employed as energetic burn rate inhibitors. The metal ions (Ba2+, K+, and Ca2+) are elaborately selected based on their ability of suppressing the burn rate of composite propellants. The CL-20 crystals were intercalated with prepared TAGP-Ms materials via a solvent-antisolvent method for realization of the precise control on burning behaviors of studied propellants. The influence of TAGP-Ms inhibitors on thermal decomposition and combustion characteristics of high-energy composite propellants was evaluated using thermal analysis and a combustion diagnostic method. Results of TGA/DSC-FTIR measurements suggest that the thermal decomposition of CL-20-containing composite propellants was found to be constrained by varied degrees as a result of TAGP-Ms additions, in which the TAGP-K displays a stronger effect on suppressing the thermal decomposition of CL-20 compared with that of other TAGP-Ms. The FTIR spectra indicate that the primary gaseous phase products are composed of N2O, H2O, and CO2 in CL-20 decomposition, as well as by HCl, H2O, NO2, and N2O in the decomposition of AP for all studied composite propellants. The combustion characterizations show that the TAGP-K-containing composite propellant exhibits a significantly reduced rate of heat release but is associated with a higher flame radiation intensity increased by 4.2% compared with that of the reference propellant, which clearly implies that the TAGP-K is capable of suppressing the energy release rate while ensuring the high energetic features of propellants to be well maintained. Moreover, the burn rate pressure exponents are considerably decreased by ∼10% for the TAGP-K-containing propellants in comparison with those of propellants with the typical formulation, which strongly suggests that TGAP-Ms are promising candidates for tuning the combustion behaviors of composite propellants by influencing the decomposition processes of CL-20 and AP collectively.

Detector-trigger-based cardiac multiphase micro-CT imaging for small animals.

BACKGROUND: Micro-computed tomography is important in cardiac imaging for preclinical small animal models, but motion artifacts may appear due to the rapid heart rates. To avoid influence of motion artifacts, the prospective ECG gating schemes based on an X-ray source trigger have been investigated. However, due to the lack of pulsed X-ray exposure modes, high-resolution micro-focus X-ray sources do not support source triggering in most cases. OBJECTIVE: To develop a fast-cardiac multiphase acquisition strategy using prospective ECG gating for micro-focus X-ray tubes with a continuous emission mode. METHODS: The proposed detector-trigger-based prospective ECG gating acquisition scheme (DTB-PG) triggers the X-ray detector at the R peak of ECG, and then collects multiple phase projections of the heart in one ECG cycle by sequence acquisition. Cardiac multiphase images are reconstructed after performing the same acquisition in all views. The feasibility of this strategy was verified in multiphase imaging experiments of a phantom with 150 ms motion period and a mouse heart on a micro-focus micro-CT system with continuous emission mode. RESULTS: Using a high frame-rate CMOS detector, DTB-PG discriminates the positions of the motion phantom well in 10 different phases and enables to distinguish the changes in the cardiac volume of the mouse in different phases. The acquisition rate of DTB-PG is much faster than other prospective gating schemes as demonstrated by theoretical analysis. CONCLUSIONS: DTB-PG combines the advantages of prospective ECG gating strategies and X-ray detector-trigger mode to suppress motion artifacts, achieve ultra-fast acquisition rates, and relax hardware limitations.

Relationship between complications of type 2 diabetes and thyroid nodules.

OBJECTIVE: Recent evidence suggests that diabetes is a risk factor for thyroid nodules. However, the relationship between complications of type 2 diabetes and the risk of thyroid nodules remains unclear. This present study aims to investigate the association between thyroid nodules and complications of type 2 diabetes. METHODS: This retrospective study collected 4696 adult inpatients with type 2 diabetes between January 2021 and December 2021. The complications examined in this paper included diabetic nephropathy, peripheral neuropathy, eye disorder, and peripheral vascular disease. RESULTS: A total of 4696 patients with type 2 diabetes participated in the study, of whom 19.6% had thyroid nodules. Among all the complications, eye disorder had the highest incidence of thyroid nodules (incidence rate, 29.4%; 95% CI, 26.23%-32.51%). The prevalence of thyroid nodules was lower among patients without complications (incidence rate, 14.1%; 95% CI, 12.48% -15.67%) compared to patients who had complications (incidence rate, 23.1%; 95% CI, 21.59%-24.68%) (p < 0.001). Logistic regression revealed that peripheral neuropathy (adjusted OR, 1.6; 95% CI, 1.4-1.9), eye disorder (adjusted OR, 1.8; 95% CI, 1.5-2.2), and peripheral vascular disease (adjusted OR, 1.8; 95% CI, 1.6-2.1) were all significantly associated with an increased risk of thyroid nodules. However, no significant correlation was found between diabetic nephropathy and the risk of thyroid nodules. CONCLUSION: One of the key findings of this study is that type 2 diabetes without complications is negatively correlated with the risk of thyroid nodules, while several complications are associated with a significantly increased risk of thyroid nodules.

3D directional gradient L0 norm minimization guided limited-view reconstruction in a dual-panel positron emission mammography.

BACKGROUND: Dual-panel PET is often used for local organ imaging, especially breast imaging, due to its simple structure, high sensitivity, good in-plane resolution, and straightforward fusion with other imaging modalities. Nevertheless, because of data loss caused by the dual-panel structure, using conventional image reconstruction methods results in limited-view artifacts and low image quality in dual-panel positron emission mammography (PEM), which may seriously affect the diagnosis. To mitigate the limited-view artifacts in the dual-panel PEM, we propose a 3D directional gradient L0 norm minimization (3D-DL0) guided reconstruction method. METHODS: The detailed derivation and reasonable simplification of the 3D-DL0 algorithm are given first. Using this algorithm, we then obtain a prior image with edge recovery but contrast loss. To limit the solution space, the 3D-DL0 prior is introduced into the Maximum a Posteriori reconstruction. Meanwhile, a space-invariant point spread function is also implemented to restore image contrast and boundaries. Finally, the reconstructed images with limited-view artifact suppression are obtained. The proposed method was evaluated using the data acquired from physical phantoms and patients with breast tumors on a commercial dual-panel PET system. RESULTS: The qualitative and quantitative studies for phantom data and the blind reader study for clinical data show that the proposed method is more effective in reaching a balance between artifact elimination and image contrast improvement compared with various limited-view reconstruction methods. In addition, the iteration process of the method is proved convergent numerically. CONCLUSIONS: The image quality improvement confirms the potential value of the proposed reconstruction algorithm to address the limited-view problem, and thus improve diagnostic accuracy in dual-panel PEM imaging.

Thermal Reactivity of High-Density Hybrid Hexahydro-1,3,5-trinitro-1,3,5-triazine Crystals Prepared by a Microfluidic Crystallization Method.

In this paper, the two-dimensional (2D) high nitrogen triaminoguanidine-glyoxal polymer (TAGP) has been used to dope hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) crystals using a microfluidic crystallization method. A series of constraint TAGP-doped RDX crystals using a microfluidic mixer (so-called controlled qy-RDX) with higher bulk density and better thermal stability have been obtained as a result of the granulometric gradation. The crystal structure and thermal reactivity properties of qy-RDX are largely affected by the mixing speed of the solvent and antisolvent. In particular, the bulk density of qy-RDX could be slightly changed in the range from 1.78 to 1.85 g cm-3 as a result of varied mixing states. The obtained qy-RDX crystals have better thermal stability than pristine RDX, showing a higher exothermic peak temperature and an endothermic peak temperature with a higher heat release. Ea for thermal decomposition of controlled qy-RDX is 105.3 kJ mol-1, which is 20 kJ mol-1 lower than that of pure RDX. The controlled qy-RDX samples with lower Ea followed the random 2D nucleation and nucleus growth (A2) model, whereas controlled qy-RDX with higher Ea (122.8 and 122.7 kJ mol-1) following some complex model between A2 and the random chain scission (L2) model.

Prevalence, awareness, and treatment of isolated diastolic hypertension in the United States.

BACKGROUND: Isolated diastolic hypertension (IDH) is recognized as a risk factor for cardiovascular disease, yet its clinical epidemiology remains poorly understood due to insufficient recognition. This study aims to describe the trend in the prevalence, awareness, and treatment of IDH in the United States from 2001 to 2018. METHODS: This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted in nine consecutive two-year cycles from 2001-2002 to 2017-2018, comprising a sample of 48,742 adults aged over 18 years. IDH was defined as a diastolic blood pressure ≥ 80 mm Hg with a systolic BP < 130 mm Hg by the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines. RESULTS: In the nationally representative dataset, 8.9% of participants had IDH in 2017-2018, a decreased of 3.6% (95% confidence interval [CI], -2.6% to -5.0%, P<0.0002) since 2001-2002. IDH prevalence was highest among Mexican American (10.5%), individuals aged 40-59 (12.3%), increased with body mass index (BMI) (11.2% among those BMI ≥30.0 kg/m2), and tended to be higher in men (12.3%). A multiple regression analysis showed that men, white race/ethnicity, young and middle-aged people (aged 18-59), and increasing BMI were independently associated with increased risks of IDH. Among IDH patients, there was a modest increase in awareness (P<0.0002), from 22.4% (95%CI, 18.4% to 27.1%) in 2001-2002 to 35.0% (95%CI, 28.2% to 42.5%) in 2017-2018, with the largest percentage increases among non-Hispanic white and men. IDH treatment increased by 7.6% (95%CI, 3.1% to 12.1%) between 2001-2002 and 2017-2018, with the greatest increases occurring in Mexican American and men. CONCLUSION: IDH prevalence is decreasing from 2001-2002 to 2017-2018 in the United States. Despite the significantly increased in both awareness and treatment, they remain below 50%.

Clinical efficacy of transforaminal endoscopic discectomy in the treatment of recurrent lumbar disc herniation: a single-center retrospective analysis.

PURPOSE: To investigate the clinical efficacy of transforaminal endoscopic discectomy (TED) in treating recurrent lumbar disc herniation. METHODS: Clinical datal of 31 patients who were hospitalized in the Department of Pain Management, First Affiliated Hospital of Nanchang University, between 2015 and 2018 due to recurrent lumbar disc herniation were collected and analyzed retrospectively. Visual analogue scale (VAS) scores and Japanese Orthopedic Association (JOA) scores were used to assess alterations of patients' leg pain intensity and nerve function, respectively. The Modified MacNab criteria were used to evaluate patients' excellent and good rates. RESULTS: Compared to clinical data before surgery, there was a significant reduction in VAS scores (P < 0.01) along with a significant improvement in JOA scores (P < 0.01) at 2 years after revision surgery. The patients' excellent and good rates were 83.9% at the 2 years after surgery. CONCLUSION: The TED is safe and effective in the long term and is applicable to the treatment of recurrent lumbar disc herniation.

Network pharmacology and LC-MS approachs to explore the active compounds and mechanisms of Yuanjiang decoction for treating bradyarrhythmia.

BACKGROUND: Yuanjiang decoction (YJD), a traditional Chinese medicinal prescription, has been found to have a significant heart rate-increasing effect and is effective in the treatment of symptomatic bradyarrhythmia in previous studies. However, its specific components and potential mechanisms remain unclear. METHODS: In this study, we detected and identified the main compounds of YJD using liquid chromatography-mass spectrometry (LC-MS). Through the approach of network pharmacology, we predicted the core targets of the active components, bradyarrhythmia targets, and obtained potential anti-bradyarrhythmia targets of YJD. We further performed protein to protein interaction (PPI), gene ontology (GO) enrichment analyses and kyoto encyclopedia of genes and genomes (KEGG) signaling pathway analyses for core targets, and constructed network of key active ingredients-core targets of YJD. Finally, molecular docking and molecular dynamics simulation were performed for key active ingredients and core targets. RESULTS: The YJD contains a total of 35 main chemical components. The key active ingredients-core targets network contains 36 nodes and 90 edges, including 20 key active ingredients and 16 core targets. The core targets in the PPI network were TP53, TNF, HRAS, PPARG, IL1B, KCNH2, SCN5A, IDH1, LMNA, ACHE, F2, DRD2, CALM1, KCNQ1, TNNI3, IDH2 and TNNT2. KEGG pathway analysis showed that YJD treatment of bradyarrhythmia mainly involves neuroactive ligand-receptor interaction, adrenergic signaling in cardiomyocytes, cAMP signaling pathway, calcium signaling pathway, cholinergic synaptic and serotonergic synapse signaling pathway. The biological processes mainly include regulation of hormone levels, regulation of cardiac contraction, chemical synaptic transmission, circadian rhythm, positive regulation of heart rate, smooth muscle contraction, response to metal ion, oxidation-reduction process, neurotransmitter transport and import across plasma membrane. Molecular docking and molecular dynamics simulation results showed that hesperidin and tetrahydropalmatine had higher affinity with DRD2 and KCNQ1, respectively. CONCLUSION: This study reveals the pharmacodynamic material basis of YJD and its potential multicomponent-multitarget-multipathway pharmacological effects, predicted its potential anti-bradyarrhythmia mechanism may be related to the regulation of myocardial autonomic nervous function and related ion channels. Our work demonstrates that YJD has great potential for treating bradyarrhythmias as a complementary medicine, and the results can provide a theoretical basis for the development and clinical application of YJD.

Thalamocortical Circuit Controls Neuropathic Pain via Up-regulation of HCN2 in the Ventral Posterolateral Thalamus.

The thalamocortical (TC) circuit is closely associated with pain processing. The hyperpolarization-activated cyclic nucleotide-gated (HCN) 2 channel is predominantly expressed in the ventral posterolateral thalamus (VPL) that has been shown to mediate neuropathic pain. However, the role of VPL HCN2 in modulating TC circuit activity is largely unknown. Here, by using optogenetics, neuronal tracing, electrophysiological recordings, and virus knockdown strategies, we showed that the activation of VPL TC neurons potentiates excitatory synaptic transmission to the hindlimb region of the primary somatosensory cortex (S1HL) as well as mechanical hypersensitivity following spared nerve injury (SNI)-induced neuropathic pain in mice. Either pharmacological blockade or virus knockdown of HCN2 (shRNA-Hcn2) in the VPL was sufficient to alleviate SNI-induced hyperalgesia. Moreover, shRNA-Hcn2 decreased the excitability of TC neurons and synaptic transmission of the VPL-S1HL circuit. Together, our studies provide a novel mechanism by which HCN2 enhances the excitability of the TC circuit to facilitate neuropathic pain.

Effect of comorbidity assessed by the Charlson Comorbidity Index on the length of stay, costs, and mortality among colorectal cancer patients undergoing colorectal surgery.

OBJECTIVE: Charlson Comorbidity Index (CCI) is a good predictor for hospitalization cost and mortality among patients with chronic disease. However, the impact of CCI on patients after colorectal cancer surgery is unclear. This study aims to investigate the influence of comorbidity assessed by CCI on length of stay, hospitalization costs, and in-hospital mortality in patients with colorectal cancer (CRC) who underwent surgical resection. METHODS: This historical cohort study collected 10,271 adult inpatients for CRC undergoing resection surgery in 33 tertiary hospitals between January 2018 and December 2019. All patients were categorized by the CCI score into four classes: 0, 1,2, and ≥3. Linear regression was used for outcome indicators as continuous variables and logical regression for categorical variables. EmpowerStats software and R were used for data analysis. RESULTS: Of all 10,271 CRC patients, 51.72% had at least one comorbidity. Prevalence of metastatic solid tumor (19.68%, except colorectal cancer) and diabetes without complication (15.01%) were the major comorbidities. The highest average cost of hospitalization (86,761.88 CNY), length of stay (18.13 days), and in-hospital mortality (0.89%) were observed in patients with CCI score ≥3 compared to lower CCI scores (p < .001). Multivariate regression analysis showed that the CCI score was associated with hospitalization costs (ß, 7340.46 [95% confidence interval (CI) (5710.06-8970.86)], p < .001), length of stay (ß, 1.91[95%CI (1.52-2.30)], p < .001), and in-hospital mortality(odds ratio (OR),16.83[95%CI (2.23-126.88)], p = .0062) after adjusted basic clinical characteristics, especially when CCI score ≥3. Notably, the most specific complication associated with hospitalization costs and length of stay was metastatic solid tumor, while the most notable mortality-specific comorbidity was moderate or severe renal disease. CONCLUSION: The research work has discovered a strong link between CCI and clinical plus economic outcomes in patients with CRC who underwent surgical resection.

Esketamine improves propofol-induced brain injury and cognitive impairment in rats.

As an intravenous anesthetic, propofol has been indicated to induce neurotoxicity in both animal and human brains. It is of great significance to better understand the potential mechanism of propofol-induced neurotoxicity to eliminate the side effects of propofol. Esketamine is a sedative that has been proven to have an antidepressant effect. However, its effect on propofol-induced neurotoxicity and the underlying mechanism remain unclear. Herein, we investigated the role of esketamine in propofol-induced brain injury. A rat model of propofol-induced brain injury was established with or without the treatment of esketamine. The results demonstrated that propofol-induced impairment in spatial learning and memory of rats and promoted oxidative stress, neuronal injury and apoptosis in rat hippocampal tissues. The effects caused by propofol were attenuated by esketamine. Esketamine activated the mature brain-derived neurotrophic factor/tropomyosin receptor kinase B/phosphatidylinositide 3-kinase (mBDNF/TrkB/PI3K) signaling pathway in propofol-administrated rats. Moreover, knocking down BDNF partially reversed esketamine-mediated activation of the mBDNF/TrkB/PI3K signaling pathway and inhibition of neuronal apoptosis in propofol-induced rats. Overall, esketamine mitigates propofol-induced cognitive dysfunction and brain injury in rats by activating mBDNF/TrkB/PI3K signaling.

Analysis of prescription medication rules of traditional Chinese medicine for bradyarrhythmia treatment based on data mining.

BACKGROUND: Multiple studies have revealed that Traditional Chinese Medicine (TCM) prescriptions can provide protective effect on the cardiovascular system, increase the heart rate and relieve the symptoms of patients with bradyarrhythmia. In China, the TCM treatment of bradyarrhythmia is very common, which is also an effective complementary therapy. In order to further understand the application of Chinese medicines in bradyarrhythmia, we analyzed the medication rules of TCM prescriptions for bradyarrhythmia by data mining methods based on previous clinical studies. METHODS: We searched studies reporting the clinical effect of TCM on bradyarrhythmia in the PubMed and Chinese databases China National Knowledge Infrastructure database, and estimated publication bias by risk of bias tools ROB 2. Descriptive analysis, hierarchical clustering analysis and association rule analysis based on Apriori algorithm were carried out by Microsoft Excel, SPSS Modeler, SPSS Statistics and Rstidio, respectively. Association rules, co-occurrence and clustering among Chinese medicines were found. RESULTS: A total of 48 studies were included in our study. Among the total 99 kinds of Chinese medicines, 22 high-frequency herbs were included. Four new prescriptions were obtained by hierarchical cluster analysis. 81 association rules were found based on association rule analysis, and a core prescription was intuitively based on the grouping matrix of the top 15 association rules (based on confidence level), of which Guizhi, Zhigancao, Wuweizi, Chuanxiong, Danshen, Danggui, Huangqi, Maidong, Dangshen, Rougui were the most strongly correlated herbs and in the core position. CONCLUSION: In this study, data mining strategy was applied to explore the TCM prescription for the treatment of bradyarrhythmia, and high-frequency herbs and core prescription were found. The core prescription was in line with the treatment ideas of TCM for bradyarrhythmia, which could intervene the disease from different aspects and adjust the patient's Qi, blood, Yin and Yang, so as to achieve the purpose of treatment.

The global burden of periodontal diseases in 204 countries and territories from 1990 to 2019.

AIMS: The aim of this study was to report the incidence, prevalence, and disability-adjusted life-years (DALYs) of periodontal diseases during the period 1990-2019. METHODS: Data on periodontal diseases were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors study (GBD) 2019. The estimated annual percentage changes were calculated to evaluate the changing trend of age-standardized incidence, prevalence, and DALY rates related to periodontal diseases. RESULTS: Globally, there were 1,087,367,744.0 cases with 91,518,820.6 new incidence and 7,090,390.3 DALYs of periodontal diseases in 2019, almost twice as many as in 1990. Moreover, the pace of increase in age-standardized incidence, age-standardized prevalence, and age-standardized DALY rates had accelerated during the 1990-2019 time period, with EAPC of 0.29 (95% CI, 0.22 to 0.35), 0.34 (95% CI, 0.26 to 0.43), and 0.35 (95% CI, 0.27 to 0.44) separately. The corresponding age-standardized percentage changes were more pronounced in females, Southeast Asia, and low-middle SDI regions. Western Sub-Saharan Africa was the high-risk area of standardized periodontal diseases burden in 2019, among which Gambia was the country with the heaviest burden. CONCLUSION: The globally incidence, prevalence, and DALYs of periodontal diseases are substantially increased from 1990 to 2019, which highlights the importance and urgency of periodontal care.

The global burden of type 2 diabetes attributable to high body mass index in 204 countries and territories, 1990-2019: An analysis of the Global Burden of Disease Study.

Background: High body mass index (BMI) plays a critical role in the initiation and development of type 2 diabetes (T2D). Up to now, far too little attention has been paid to the global burden of T2D attributable to high BMI. This study aims to report the deaths and disability-adjusted life years (DALYs) of T2D related to high BMI in 204 countries and territories from 1990 to 2019. Methods: Data on T2D burden attributable to high BMI were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The global cases, age-standardized rates of mortality (ASMR), and disability-adjusted life years (ASDR) attributable to high BMI were estimated by age, sex, geographical location, and socio-demographic index (SDI). The estimated annual percentage change (EAPC) was calculated to quantify the trends of ASMR and ASDR during the period 1990-2019. Results: Globally, there were 619,494.8 deaths and 34,422,224.8 DALYs of T2D attributed to high BMI in 2019, more than triple in 1990. Moreover, the pace of increase in ASMR and ASDR accelerated during 1990-2019, with EAPC of 1.36 (95% CI: 1.27 to 1.45) and 2.13 (95% CI: 2.10 to 2.17) separately, especially in men, South Asia, and low-middle SDI regions. Oceania was the high-risk area of standardized T2D deaths and DALYs attributable to high BMI in 2019, among which Fiji was the country with the heaviest burden. In terms of SDI, middle SDI regions had the biggest T2D-related ASMR and ASDR in 2019. Conclusion: The global deaths and DALYs of T2D attributable to high BMI substantially increased from 1990 to 2019. High BMI as a major public health problem needs to be tackled properly and timely in patients with T2D.

Efficient degradation of semi-coking wastewater in three-dimensional electro-Fenton by CuFe2O4 heterocatalyst.

Semi-coking wastewater contains a rich source of toxic and refractory compounds. Three-dimensional electro-Fenton (3D/EF) process used CuFe2O4 as heterocatalyst and activated carbon (AC) as particle electrode was constructed for degrading semi-coking wastewater greenly and efficiently. CuFe2O4 nanoparticles were prepared by coprecipitation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy disperse spectroscopy (EDS). Factors like dosage of CuFe2O4, applied voltage, dosage of AC and pH, which effect COD removal rate of semi-coking waste water were studied. The results showed that COD removal rate reached to 80.9% by 3D/EF process at the optimum condition: 4 V, 0.3 g of CuFe2O4, 1 g of AC and pH = 3. Trapping experiment suggesting that hydroxyl radical (•OH) is the main active radical. The surface composition and chemical states of the fresh and used CuFe2O4 were analyzed by XPS indicating that Fe, Cu, and O species are involved into the 3D/EF process. Additionally, anode oxidation and the adsorption and catalysis of AC are also contributed to the bleaching of semi-coking waste water. The possible mechanisms of 3D/EF for degrading semi-coking waste water by CuFe2O4 heterocatalyst were proposed.

Serum potassium level, variability and in-hospital mortality in acute myocardial infarction.

OBJECTIVE: Clinical guidelines recommend an optimal serum potassium concentration between 4.0 and 5.0 mmol/L in patients with acute myocardial infarction (AMI), which was based on lower-quality evidence from more than 20 years ago. Therefore, it is essential to re-evaluate the range of optimal potassium levels in patients with AMI in intensive care unit (ICU). METHODS: This was a retrospective study based on Philips eICU Collaborative Research Database, which covered 9776 patients with AMI between 2014 and 2015. All patients had more than or equal to 2 serum potassium measurements and were categorized by the mean serum potassium level (<3.5, 3.5-4.5, 4.5-5.5, ≥5.5 mmol/L) and potassium variability (1st, 2nd, and ≥3rd standard deviation (SD)). Binary logistic regression was used to determine the association between mean potassium levels, variability and in-hospital mortality in AMI. RESULTS: Of all 9776 AMI patients in ICU, 8731 (89.3%) patients were included. A total of 69847 potassium measurements were performed in these patients. There was a J-shaped relationship between mean serum potassium level and in-hospital mortality. The lowest mortality (mortality rate, 7.2%; 95% CI, 6.57%-7.76%) was observed in patients with mean potassium level between 3.5 and 4.5 mmol/L and a low potassium variability within the 1st SD. Logistic regression showed that the risk of in-hospital mortality is highest when the mean potassium level ≥5.5 mmol/L (57.6%; 95% Cl, 45.02%-70.24%; multivariable adjusted OR, 14.8; 95% CI, 8.4-26.2) compared to the reference group of 3.5-4.5 mmol/L and potassium variability within the 3rd SD (16.5%; 95% Cl, 15.19%-17.88%; multivariable adjusted OR, 3.3; 95% CI, 2.7-4.1) compared to 1st SD. Several sensitivity analyses confirmed these results. CONCLUSION: Among AMI patients in ICU, the minimum risk of in-hospital mortality was observed in those with mean potassium levels between 3.5 and 4.5 mmol/L or a minimal potassium variability compared to those who had higher or lower values.
