Green Method for the Preparation of Durable Superhydrophobic Antimicrobial Polyester Fabrics with Micro-Pleated Structures.

To produce functional protective textiles with minimal environmental footprints, we developed durable superhydrophobic antimicrobial textiles. These textiles are characterized by a micro-pleated structure on polyester fiber surfaces, achieved through a novel plasma impregnation crosslinking process. This process involved the use of water as the dispersion medium, water-soluble nanosilver monomers for antimicrobial efficacy, fluorine-free polydimethylsiloxane (PDMS) for hydrophobicity, and polyester (PET) fabric as the base material. The altered surface properties of these fabrics were extensively analyzed using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectrometry (XPS), thermogravimetric analysis (TGA), and water contact angle (WCA) measurements. The antimicrobial performance of the strains was evaluated using Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. After treatment, the fabrics exhibited enhanced hydrophobic and antimicrobial properties, which was attributed to the presence of a micro-pleated structure and nanosilver. The modified textiles demonstrated a static WCA of approximately 154° and an impressive 99.99% inhibition rate against both test microbes. Notably, the WCA remained above 140° even after 500 washing cycles or 3000 friction cycles.

Age-Related Effect of Uric Acid on Contrast-Induced Acute Kidney Injury of Patients Undergoing Coronary Angiography.

Background: The association between uric acid (UA) and contrast-induced acute kidney injury (CI-AKI) following coronary angiography (CAG) has been established. However, whether the association would vary with age remained undetermined. Methods: We performed the retrospective analysis based on the Cardio-renal Improvement II study, (ClinicalTrials.gov NCT05050877), which enrolled consecutive patients undergoing coronary angiography in 5 teaching hospitals in China from 2007 to 2020. The primary outcome was CI-AKI defined as the rise of serum creatinine (SCr) ≥ 0.5 mg/dL or 25% compared with the baseline value within 48 hours following CAG. The effect of age on the association between uric acid and CI-AKI was assessed by the logistic regression model. Results: A total of 36,550 patients (mean age 63.08±5.6-year-old, 41.7% men) were included in the study. After adjusting for the confounders, the risk of CI-AKI between each quartile of uric acid was insignificant in the young group. In patients of the middle group, lower UA was associated with a lower risk of CI-AKI while higher UA was associated with a higher risk (Q1 OR: 0.853, 95% CI: 0.734-0.993; Q4 OR: 1.797, 95% CI: 1.547-2.09). In patients of the elder group, lower and higher UA were both associated with a higher risk of CI-AKI (Q1 OR: 1.247, 95% CI: 1.003-1.553; Q4 OR: 1.688, 95% CI: 1.344-2.124). The restricted cubic spline indicated a non-linear association between UA and CI-AKI in middle and elder age groups but a linear association in the young age group. Conclusion: The association between uric acid and CI-AKI vary in patients of different age. Patients with elder age should maintain a middle level of uric acid while patients with middle age should consider a lower level of uric acid to reduce the risk of CI-AKI. The level of UA was an insignificant risk factor for CI-AKI in young patients.

Association of triglyceride-glucose index with the prevalence of cardiovascular disease in malnourished/non-malnourished patients: a large cross-sectional study.

Background: Numerous investigations have demonstrated a strong association between the TyG (triglyceride-glucose) index, which is derived from lipid and glucose levels in the bloodstream, and the onset and progression of cardiovascular diseases (CVD). Blood glucose and blood lipids are affected by nutritional status, and few studies have explored whether the correlation between TyG index and the risk of CVD is affected by nutritional status. Aims: To investigate the connection between TyG index and the risk of CVD among individuals with varying nutritional statuses. Method: A total of 19,847 were included in the analysis, of which 15,955 participants were non-malnourished and 3,892 patients were malnourished. According to the TyG index quartile, the patients were categorized into four groups. Logistic regression analysis and restricted cubic spline was used to study the relationship between TyG index and the risk of CVD in normal and malnourished populations. Results: The results of the restricted cubic spline showed that the TyG index was positively associated with the risk of CVD in the non-malnourished population. The TyG index showed a U-shaped association with the risk of CVD in malnourished people. The result is consistent with that of logistic regression (Malnutrition: Group 2: OR: 1.14; 95% CI: 0.85-1.53; Group 3: OR: 1.36; 95% CI: 1.03-1.79; Group 4: OR: 1.72; 95% CI:1.31-2.25, P for trend <0.001; Non-malnutrition: Group 2: OR: 0.82; 95% CI: 0.46-1.48; Group 3: OR: 0.88; 95% CI: 0.49-1.57; Group 4: OR: 1.45; 95% CI:0.83-2.52, P for trend =0.067). Conclusions: The association between the TyG index and the risk of CVD varied depending on the nutritional states. When using TyG index to assess the risk of CVD, stratification combined with nutritional status helps to more accurately screen patients at high risk of CVD.

Sub-50 nm perovskite-type tantalum-based oxynitride single crystals with enhanced photoactivity for water splitting.

A long-standing trade-off exists between improving crystallinity and minimizing particle size in the synthesis of perovskite-type transition-metal oxynitride photocatalysts via the thermal nitridation of commonly used metal oxide and carbonate precursors. Here, we overcome this limitation to fabricate ATaO2N (A = Sr, Ca, Ba) single nanocrystals with particle sizes of several tens of nanometers, excellent crystallinity and tunable long-wavelength response via thermal nitridation of mixtures of tantalum disulfide, metal hydroxides (A(OH)2), and molten-salt fluxes (e.g., SrCl2) as precursors. The SrTaO2N nanocrystals modified with a tailored Ir-Pt alloy@Cr2O3 cocatalyst evolved H2 around two orders of magnitude more efficiently than the previously reported SrTaO2N photocatalysts, with a record solar-to-hydrogen energy conversion efficiency of 0.15% for SrTaO2N in Z-scheme water splitting. Our findings enable the synthesis of perovskite-type transition-metal oxynitride nanocrystals by thermal nitridation and pave the way for manufacturing advanced long-wavelength-responsive particulate photocatalysts for efficient solar energy conversion.

Influence of renal function on the ability of TyG Index to predict all-cause mortality.

BACKGROUND: The association between triglyceride-glucose (TyG) index and poor prognosis remains controversial. Whether renal function status affects the ability of the TyG index to predict poor prognosis has not yet been elucidated and merits further studies. METHODS: This retrospective cohort study included 22,031 participants from communities in the U.S. By juxtaposing the TyG categories with the estimated glomerular filtration rate (eGFR, either < 60 mL/min/1.73m2 or ≥ 60 mL/min/1.73m2), participants were categorized into four distinct groups: (1) TyG_L/eGFR_H; (2) TyG_H/eGFR_H; (3) TyG_L/eGFR_L; and (4) TyG_H/eGFR_L. The endpoint was the all-cause mortality rate. Standard Kaplan-Meier plots were constructed and multifactor Cox regression analyses were carried out and restricted cubic spline regression analysis was utilized to assess the association between death and the TyG index for different renal function statuses. RESULTS: No statistical differences were found in the TyG groups in participants with normal renal function after adjustment for all covariates (P = 0.070). However, in the high TyG index group with renal insufficiency, the risk of all-cause mortality rates was reduced by 18%. (HR, 0.82; CI, 0.69-0.98). The TyG index (high vs. low) and renal function (eGFR < 60 vs. eGFR ≥ 60) had statistically significant interactions with death (P < 0.001). When all covariates were adjusted, the risk of mortality for the TyG_L combined with eGFR_L group was 56% higher than that for the TyG_L combined with eGFR_H group (HR, 1.56; CI, 1.33-1.82). In the renal insufficiency population, a nonlinear relationship was observed between mortality and the TyG index, albeit with a differing pattern (P for nonlinearity < 0.001). CONCLUSIONS: While it has been known that TyG index was a prognosis marker of CVD, this research highlights that higher TyG index was associated with higher all-cause mortality rates for all participants. Furthermore, renal function status significantly moderates the effect of the TyG index on all-cause mortality in community-dwelling adults.

Transition-metal (oxy)nitride photocatalysts for water splitting.

Solar-driven water splitting based on particulate semiconductor materials is studied as a technology for green hydrogen production. Transition-metal (oxy)nitride photocatalysts are promising materials for overall water splitting (OWS) via a one- or two-step excitation process because their band structure is suitable for water splitting under visible light. Yet, these materials suffer from low solar-to-hydrogen energy conversion efficiency (STH), mainly because of their high defect density, low charge separation and migration efficiency, sluggish surface redox reactions, and/or side reactions. Their poor thermal stability in air and under the harsh nitridation conditions required to synthesize these materials makes further material improvements difficult. Here, we review key challenges in the two different OWS systems and highlight some strategies recently identified as promising for improving photocatalytic activity. Finally, we discuss opportunities and challenges facing the future development of transition-metal (oxy)nitride-based OWS systems.

The aggregate index of systemic inflammation (AISI): a novel predictor for hypertension.

Objective: Inflammation plays an important role in the pathophysiology of hypertension (HTN). Aggregate index of systemic inflammation (AISI), as a new inflammatory and prognostic marker has emerged recently. Our goal was to determine whether there was a relationship between HTN and AISI. Methods: We analyzed patients with HTN from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. The primary end point was cardiovascular mortality. A total of 23,765 participants were divided into four groups according to the AISI quartile level. The association between AISI and cardiovascular mortality in patients with HTN was assessed by survival curves and Cox regression analyses based on NHANES recommended weights. Results: High levels of AISI were significantly associated with cardiovascular mortality in patients with HTN. After full adjustment for confounders, there was no significant difference in the risk of cardiovascular mortality in Q2 and Q3 compared to Q1, while Q4 (HR: 1.91, 95% CI: 1.42-2.58; P < 0.001) had a higher risk of cardiovascular mortality compared to Q1. Results remained similar in subgroup analyses stratified by age (P for interaction = 0.568), gender (P for interaction = 0.059), and obesity (P for interaction = 0.289). Conclusions: In adults with HTN, elevated AISI levels are significantly associated with an increased risk of cardiovascular mortality and may serve as an early warning parameter for poor prognosis.

Characterization of the LysP2110-HolP2110 Lysis System in Ralstonia solanacearum Phage P2110.

Ralstonia solanacearum, a pathogen causing widespread bacterial wilt disease in numerous crops, currently lacks an optimal control agent. Given the limitations of traditional chemical control methods, including the risk of engendering drug-resistant strains and environmental harm, there is a dire need for sustainable alternatives. One alternative is lysin proteins that selectively lyse bacteria without contributing to resistance development. This work explored the biocontrol potential of the LysP2110-HolP2110 system of Ralstonia solanacearum phage P2110. Bioinformatics analyses pinpointed this system as the primary phage-mediated host cell lysis mechanism. Our data suggest that LysP2110, a member of the Muraidase superfamily, requires HolP2110 for efficient bacterial lysis, presumably via translocation across the bacterial membrane. LysP2110 also exhibits broad-spectrum antibacterial activity in the presence of the outer membrane permeabilizer EDTA. Additionally, we identified HolP2110 as a distinct holin structure unique to the Ralstonia phages, underscoring its crucial role in controlling bacterial lysis through its effect on bacterial ATP levels. These findings provide valuable insights into the function of the LysP2110-HolP2110 lysis system and establish LysP2110 as a promising antimicrobial agent for biocontrol applications. This study underpins the potential of these findings in developing effective and environment-friendly biocontrol strategies against bacterial wilt and other crop diseases.

A more accurate method to estimate muscle mass: A new estimation equation.

BACKGROUND: Measurement of muscle mass is important in the diagnosis of sarcopenia. Current measurement equipment are neither cost-effective nor standardized and cannot be used in a variety of medical settings. Some simple measurement tools have been proposed that are subjective and unvalidated. We aimed to develop and validate a new estimation equation in a more objective and standardized way, based on current proven variables that accurately reflect muscle mass. METHODS: Cross-sectional analysis with The National Health and Nutrition Examination Survey database for equation development and validation. Overall, 9875 participants were included for development (6913 participants) and validation (2962 participants), for whom the database included demographic data, physical measurements, and main biochemical indicators. Appendicular skeletal muscle mass (ASM) was estimated by dual-energy x-ray absorptiometry (DXA) and low muscle mass was defined by reference to five international diagnostic criteria. Linear regression was used to estimate the logarithm of the actual ASM from demographic data, physical measurements, and biochemical indicators. RESULTS: This study of 9875 participants comprised 4492 females (49.0%), with a weighted mean (SE) age of 41.83 (0.36) years and range of 12 to 85 years. The estimated ASM equations performed well in the validation data set. The variability in estimated ASM was low compared with the actual ASM (R2 : Equation 1 = 0.91, Equation 4 = 0.89), with low bias (median difference: Equation 1 = -0.64, Equation 4 = 0.07; root mean square error: Equation 1 = 1.70 [1.69-1.70], Equation 4 = 1.85 [1.84-1.86]), high precision (interquartile range of the differences: Equation 1 = 1.87, Equation 4 = 2.17), and high efficacy in diagnosing low muscle mass (area under the curve: Equation 1 = 0.91 to 0.95, Equation 4 = 0.90 to 0.94). CONCLUSIONS: The estimated ASM equations are accurate and simple and can be routinely applied clinically to estimate ASM and thus assess sarcopenia.

Association between the insulin resistance marker TyG index and subsequent adverse long-term cardiovascular events in young and middle-aged US adults based on obesity status.

BACKGROUND: A lthough the triglyceride-glucose (TyG) index has been shown to closely correlate with cardiometabolic outcomes and predict cardiovascular events in many groups, it remains unclear whether obese status in young and middle-aged adults is associated with long-term unfavorable cardiovascular events. This warrants further investigation. METHODS: This retrospective cohort study analyzed data from the National Health and Nutrition Examination Survey spanning the years 1999-2018, with follow-up for mortality status until December 31, 2019. To categorize participants based on the TyG level, the optimal critical value was determined through restricted cubic spline function analysis, dividing them into high and low TyG groups. The study assessed the relationship between TyG and cardiovascular events and all-cause mortality in young and middle-aged adults stratified by obesity status. Kaplan‒Meier and Cox proportional risk models were used to analyze the data. RESULTS: During a follow-up period of 123 months, a high TyG index increased the risk of cardiovascular events by 63% (P = 0.040) and the risk of all-cause mortality by 32% (P = 0.010) in individuals after adjusting for all covariates. High TyG was shown to be linked to cardiovascular events in obese people (Model 3: HR = 2.42, 95% CI = 1.13-5.12, P = 0.020); however, there was no significant difference in TyG groups for nonobese adults in Model 3 (P = 0.08). CONCLUSIONS: TyG was independently associated with harmful long-term cardiovascular events in young and middle-aged US populations, with a stronger association observed in those who were obese.

Dietary inflammatory potential is associated with sarcopenia in patients with hypertension: national health and nutrition examination study.

Background: Study has shown that sarcopenia increases the risk of poor outcomes in patients with hypertension. Inflammation is one of the important reasons for the occurrence and development of sarcopenia. Regulating systemic inflammation may be a potential intervention for sarcopenia in hypertensive patients. Diet is one of the important measures to improve systemic inflammation. The dietary inflammatory index (DII) is a tool designed to assess the inflammatory potential of the diet, the association between DII and sarcopenia in hypertensive patients is unclear. Objective: To explore the relationship between the DII and sarcopenia in patients with hypertension. Method: Data from the National Health and Nutrition Examination Survey (NHANES) 1999-2006 and 2011-2018. A total of 7,829 participants were evaluated. Participants were divided into four groups based on the quartile of the DII: Q1 group (n = 1,958), Q2 group (n = 1,956), Q3 group (n = 1,958) and Q4 group (n = 1,957). The relationship between the DII and sarcopenia was assessed by logistic regression analysis based on the NHANES recommended weights. Result: The DII was significantly associated with sarcopenia in patients with hypertension. After full adjustment, patients with higher DII (OR: 1.22, 95% CI: 1.13-1.32, p < 0.001) have a higher risk of sarcopenia. Compared with Q1 group, the group with higher DII levels had a higher risk of sarcopenia (Q2: OR: 1.23, 95%CI: 0.89-1.72, p = 0.209; Q3: OR: 1.68, 95%CI: 1.20-2.35, p = 0.003; Q4: OR: 2.43, 95%CI: 1.74-3.39, p < 0.001). Conclusion: High DII is associated with an increased risk of sarcopenia in hypertensive patients. The higher the level of DII, the higher the risk of sarcopenia in hypertensive patients.

Advanced lung cancer inflammation index is associated with long-term cardiovascular death in hypertensive patients: national health and nutrition examination study, 1999-2018.

Background: Hypertension is one of the main causes of cardiovascular death. Inflammation was considered influential factors of cardiovascular (CVD) death in patients with hypertension. Advanced lung cancer inflammation index (ALI) is an index to assess inflammation, few studies have investigated the relationship between advanced lung cancer inflammation index and cardiovascular death in hypertensive patients. Objective: The aim of this study was to investigate the association between advanced lung cancer inflammation index and long-term cardiovascular death in hypertensive patients. Method: Data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 with mortality follow-up through 31 December 2019 were analyzed. Advanced lung cancer inflammation index was calculated as BMI (kg/㎡) × serum albumin level (g/dL)/neutrophil to lymphocyte ratio (NLR). A total of 20,517 participants were evaluated. Patients were divided into three groups based on tertiles of advanced lung cancer inflammation index as follows: T1 (n = 6,839), T2 (n = 6,839), and T3 (n = 6,839) groups. The relationship between advanced lung cancer inflammation index and long-term cardiovascular death was assessed by survival curves and Cox regression analysis based on the NHANES recommended weights. Results: The median advanced lung cancer inflammation index value in this study was 61.9 [44.4, 84.6]. After full adjustment, the T2 group (hazard ratio [HR]: 0.59, 95% confidence interval [CI]: 0.50-0.69; p < 0.001) and T3 group (HR: 0.48, 95% CI: 0.39-0.58; p < 0.001) were found to have a significantly lower risk of cardiovascular death compared to the T1 group. Conclusion: High levels of advanced lung cancer inflammation index were associated with reduced risk of cardiovascular death in hypertensive patients.

Predictors of mortality in heart failure with reduced ejection fraction: interaction between diabetes mellitus and impaired renal function.

BACKGROUND: The harmful effect of diabetes mellitus (DM) on mortality in patients with heart failure with reduced ejection fraction (HFrEF) remains controversial. Furthermore, it seems that no consistent conclusion on whether chronic kidney disease (CKD) modifies the relationship of DM and poor prognosis in patients with HFrEF. METHODS: We analyzed the individuals with HFrEF from the Cardiorenal ImprovemeNt (CIN) cohort between January 2007 and December 2018. The primary endpoint was all-cause mortality. The patients were divided into four groups (control vs. DM alone vs. CKD alone vs. DM and CKD). Multivariate Cox proportional hazards analysis was conducted to examine the association among DM, CKD and all-cause mortality. RESULTS: There were 3,273 patients included in this study (mean age: 62.7 ± 10.9 years, 20.4% were female). During a median follow-up of 5.0 years (interquartile range: 3.0-7.6 years), 740 (22.6%) patients died. Patients with DM have a higher risk of all-cause mortality (HR [95% confidence interval (CI)]:1.28[1.07-1.53]) than those without DM. In patients with CKD, DM had a 61% (HR [95% CI]:1.61[1.26-2.06]) increased adjusted risk of death relative to non-DM, while in patients with non-CKD, there was no significantly difference in risk of all-cause mortality (HR [95% CI]:1.01[0.77-1.32]) between DM and non-DM (p for interaction = 0.013). CONCLUSIONS: Diabetes is a potent risk factor for mortality in patients with HFrEF. Furthermore, DM had a substantially different effect on all-cause mortality depending on CKD. The association between DM and all-cause mortality was only observed in patients with CKD.

Intestinal obstruction caused by mesodiverticular band in children: a cohort study.

OBJECTIVE: To explore clinical characteristics, pathogenesis, diagnosis and treatment of intestinal obstruction due to mesodiverticular band (MDB) in children in a single center in China. METHODS: The clinical data of 20 children with acute intestinal obstruction due to MDB between 1998 and 2020 were retrospectively analyzed. RESULTS: The male-to-female ratio was 14:6 in 20 cases. Except one case of 7-month pregnant stillbirth, the cases were aged from 7 days to 14 years, at the median age of 4.31 years. The common symptoms were vomiting, abdominal pain and/or abdominal distension. About 40% (8/20) of patients had both MDB and Meckel's Diverticulum (MD), while 60% (12/20) of patients had MDB only. Only one case died because of total colonic aganglionosis, while other children recovered after surgery treatment. MDB led to the strangulation of necrotic bowel in six cases, intestinal perforation in one case, and intestinal rupture in one case. Pathologic examination showed thick-walled arteries and or thick venous vascular structures in the cord. All cases had no complications during 1-year follow-up. CONCLUSION: MDB results from the remnant of vitelline vessel, and often causes acute intestinal obstruction without special clinical symptoms. Unexplained abdominal pain and distension without surgery history should be paid attention, especially for strangulated intestinal obstruction. Timely surgical exploration is beneficial to avoid intestinal necrosis or even sudden death, and the pathological examination is important for the diagnosis.

Overall Water Splitting by a SrTaO2N-Based Photocatalyst Decorated with an Ir-Promoted Ru-Based Cocatalyst.

The development of narrow-bandgap photocatalysts for one-step-excitation overall water splitting (OWS) remains a critical challenge in the field of solar hydrogen production. SrTaO2N is a photocatalytic material having a band structure suitable for OWS under visible light (λ ≤ 600 nm). However, the presence of defects in the oxynitride and the lack of cocatalysts to promote simultaneous hydrogen and oxygen evolution make it challenging to realize OWS using this material. The present work demonstrates a SrTaO2N-based particulate photocatalyst for OWS. This photocatalyst, which was composed of single crystals, was obtained by nitriding SrCl2 and Ta2O5 together with NaOH, with the latter added to control the formation of defects. The subsequent loading of bimetallic RuIrOx nanoparticles accelerated charge separation and allowed the SrTaO2N photocatalyst to exhibit superior OWS activity. This research presenting the strategies of controlling the oxygen sources and promoting the cocatalyst function is expected to expand the range of potential OWS-active oxynitride photocatalysts and permit the design of efficient cocatalysts for photocatalytic OWS.

The advanced lung cancer inflammation index predicts long-term outcomes in patients with hypertension: National health and nutrition examination study, 1999-2014.

Background: Malnutrition and systemic inflammation are associated with poor outcomes in patients with hypertension, and the two often coexist. However, few studies have combined nutritional and inflammatory status to assess the prognosis of patients with hypertension. The present study aimed to investigate the association between advanced lung cancer inflammation index (ALI), as a factor assessment the nutritional and inflammatory status, and long-term all-cause mortality of patients with hypertension. Materials and methods: Data from the National Health and Nutrition Examination Survey (NHANES) 1999-2014 with mortality follow-up through December 31, 2015, were analyzed. A total of 15,681 participants were evaluated. The patients were grouped based on the ALI tertiles as follows: T1 (ALI ≤ 49.41, n = 5,222), T2 (ALI > 49.41 and ≤ 76.29, n = 5,221), and T3 (ALI > 76.29, n = 5,237) groups. Survival curves and Cox regression analysis based on the NHANES recommended weights were used to assess the relationship between nutritional and inflammatory status and long-term all-cause mortality. Results: Advanced lung cancer inflammation index was significantly associated with long-term all-cause mortality in patients with hypertension. After adjustment for related factors, the T2 [hazard ratio (HR): 0.69, 95% confidence interval (CI): 0.58-0.83; P < 0.001) and T3 (HR: 0.59, 95% CI: 0.47-0.74; P < 0.001) groups were significantly associated with a decreased risk of all-cause mortality compared to the lower ALI level group (T1). Conclusion: Advanced lung cancer inflammation index was a comprehensive index of nutrition and inflammation and an independent significant prognostic factor in hypertension patients in the American community. Systemic inflammatory and nutritional status assessment and monitoring are essential for the health of hypertensive patients.

Prognostic value of creatinine-to-cystatin c ratio in patients with type 2 diabetes mellitus: a cohort study.

BACKGROUND: The serum creatinine-to-cystatin C ratio (Scr/Scys) has been suggested as a surrogate marker of muscle mass and a predictor of adverse outcomes in many diseases. However, the prognostic value of Scr/Scys in patients with type 2 diabetes mellitus (T2DM) is unknown. The aim of this study is to assess the prognostic value of Scr/Scys in patients with T2DM. METHODS: In this retrospective observational study, we enrolled 3668 T2DM patients undergoing coronary angiography (CAG). Serum creatinine (Scr) and serum cystatin C (Scys) levels were measured at admission. The study population was separated into low muscle mass (low-MM) and normal muscle mass (normal-MM) groups by Scr/Scys cut-off point. The association between muscle mass and long-term all-cause mortality was examined using Cox regression analysis. RESULTS: During a median follow-up of 4.9 (3.0-7.1) years, a total of 352 (9.6%) patients died. The mortality was higher in patients with low-MM as compared with patients with normal-MM (11.1% vs. 7.3%; p < 0.001). Low muscle mass was associated with increased risk for long-term all-cause mortality, regardless of whether Scr/Scys were used as a continuous variable (adjusted hazard ratio: 1.08 [95% confidence interval (CI) 1.03 to 1.13]; p = 0.009) or a categorial variable (adjusted hazard ratio: 1.36 [95% CI 1.03 to 1.75]; p = 0.021). CONCLUSION: Low muscle mass assessed by Scr/Scys was associated with increased risk of long-term all-cause mortality in diabetic patients.

Nutrition-related diseases and cardiovascular mortality in American society: national health and nutrition examination study, 1999-2006.

BACKGROUND: Despite many significant advances in treatment and management, cardiovascular disease remains the main cause of the global disease burden. Nutrition-related disease is a modifiable cardiovascular risk factor. However, few studies have examined the relationship between nutrition-related diseases and cardiovascular mortality. OBJECTIVE: We aimed to investigate the association of nutrition-related diseases with cardiovascular mortality based on a large nationally representative community population. DESIGN: We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 1999-2006 with mortality follow-up through December 31, 2015. Finally, 12,469 participants were analyzed. Each participant was assigned to one of four groups: normal nutrition without sarcopenia, sarcopenia with normal nutrition, malnutrition without sarcopenia, and malnutrition-sarcopenia syndrome. Survival curves and Cox regressions based on the NHANES recommended weights were used to assess the association between nutrition-related diseases and cardiovascular mortality. RESULTS: Of the 12,469 patients included in the study and divided into four groups, malnutrition-sarcopenia syndrome had the highest 5- and 10-year cardiovascular mortality rates. After adjustment for related factors, sarcopenia with normal nutrition (hazard ratio [HR]: 1.62, 95% confidence interval [CI]: 1.28-2.06; P < 0.001), malnutrition without sarcopenia (HR: 1.28, 95% CI:1.03-1.58; P = 0.024), and malnutrition-sarcopenia syndrome (HR: 2.66, 95% CI:1.89 - 3.74; P < 0.001) were significantly associated with increased risk of all-cause mortality. Malnutrition-sarcopenia syndrome remained associated with an increased risk of cardiovascular mortality (HR: 3.56, 95% CI: 1.17 - 10.84; P < 0.001). CONCLUSIONS: Malnutrition-sarcopenia syndrome was highly prevalent among community-dwelling adults in the United States and was a strong prognostic factor for cardiovascular mortality in the community setting. Randomized clinical trials are needed to demonstrate whether prevention or treatment of malnutrition-sarcopenia syndrome in community populations can reduce global cardiovascular mortality.

Immune depletion of the methylated phenotype of colon cancer is closely related to resistance to immune checkpoint inhibitors.

Background: Molecular typing based on single omics data has its limitations and requires effective integration of multiple omics data for tumor typing of colorectal cancer (CRC). Methods: Transcriptome expression, DNA methylation, somatic mutation, clinicopathological information, and copy number variation were retrieved from TCGA, UCSC Xena, cBioPortal, FireBrowse, or GEO. After pre-processing and calculating the clustering prediction index (CPI) with gap statistics, integrative clustering analysis was conducted via MOVICS. The tumor microenvironment (TME) was deconvolved using several algorithms such as GSVA, MCPcounter, ESTIMATE, and PCA. The metabolism-relevant pathways were extracted through ssGSEA. Differential analysis was based on limma and enrichment analysis was carried out by Enrichr. DNA methylation and transcriptome expression were integrated via ELMER. Finally, nearest template or hemotherapeutic sensitivity prediction was conducted using NTP or pRRophetic. Results: Three molecular subtypes (CS1, CS2, and CS3) were recognized by integrating transcriptome, DNA methylation, and driver mutations. CRC patients in CS3 had the most favorable prognosis. A total of 90 differentially mutated genes among the three CSs were obtained, and CS3 displayed the highest tumor mutation burden (TMB), while significant instability across the entire chromosome was observed in the CS2 group. A total of 30 upregulated mRNAs served as classifiers were identified and the similar diversity in clinical outcomes of CS3 was validated in four external datasets. The heterogeneity in the TME and metabolism-related pathways were also observed in the three CSs. Furthermore, we found CS2 tended to loss methylations while CS3 tended to gain methylations. Univariate and multivariate Cox regression revealed that the subtypes were independent prognostic factors. For the drug sensitivity analysis, we found patients in CS2 were more sensitive to ABT.263, NSC.87877, BIRB.0796, and PAC.1. By Integrating with the DNA mutation and RNA expression in CS3, we identified that SOX9, a specific marker of CS3, was higher in the tumor than tumor adjacent by IHC in the in-house cohort and public cohort. Conclusion: The molecular subtypes based on integrated multi-omics uncovered new insights into the prognosis, mechanisms, and clinical therapeutic targets for CRC.

Association of sarcopenia with ideal cardiovascular health metrics among US adults: a cross-sectional study of NHANES data from 2011 to 2018.

OBJECTIVE: The American Heart Association (AHA) proposed the concept of ideal cardiovascular health (CVH) to reduce the risk of cardiovascular mortality. We attempted to broaden the impact of CVH and further contribute to AHA 2030 goals by identifying the relationship between CVH and non-cardiovascular diseases such as sarcopenia. DESIGN: Cross-sectional survey SETTING: National Health and Nutrition Examination Survey conducted in the USA from 2011 to 2018. PARTICIPANTS: This study included participants with reliable first 24-hour dietary recall and ≥20 years of age and excluded those who could not diagnose sarcopenia or insufficient data to calculate the CVH scores. PRIMARY AND SECONDARY OUTCOME MEASURES: The prevalence of sarcopenia as measured by dual-energy X-ray absorptiometry. RESULTS: This cohort study involving 9326 adults≥20 years comprised 4733 females (50.0%). The number of intermediate or ideal and poor CVH participants was 5654 and 3672 with mean CVH score of 9.70±0.03 and 5.66±0.04, respectively. After adjusting for related confounding factors, intermediate or ideal CVH was associated with an odds reduction of sarcopenia than poor CVH (adjusted OR (aOR): 0.36, 95% CI 0.26 to 0.50, p<0.001) and the odds of sarcopenia was significantly lower for each incremental increase of 1 in CVH metrics (aOR: 0.75, 95% CI 0.71 to 0.79, p<0.001). Moreover, if the number of ideal CVH metrics was>5, the odds of sarcopenia decreased by up to 84% (aOR: 0.16, 95% CI 0.08 to 0.30). CONCLUSIONS: Our findings suggest a relationship between the CVH and the prevalence of sarcopenia in adults. The results of our study can contribute to achieving the 2030 public health goal of achieving CVH for all, which may be supported by efforts to reduce the prevalence of sarcopenia.
