RESUMEN
To investigate the relationship between preoperative blood glucose levels and long-term all-cause mortality in patients with osteoporotic vertebral compression fractures (OVCF) who underwent percutaneous vertebroplasty (VP). This single-center retrospective study involved a chart review of patients admitted for VP to treat OVCF between 2013 and 2020. Patients with pathological or multiple fractures or those who did not undergo bone mineral density assessment were excluded. All relevant information was collected from electronic medical records. The survival status of all patients was confirmed at the end of March 2021. Cox proportional hazard models with multivariate adjustments were used to examine the effects of blood glucose levels on all-cause mortality. Overall, 131 patients were retrospectively analyzed (mean age: 75.8 ± 9.3 years, male patients: 26.7%) with a median follow-up period of 2.1 years. Preoperative hyperglycemia (hazard ratio: 2.668, 95% confidence interval [CI] 1.064, 6.689; p = 0.036) and glucose levels (hazard ratio: 1.007, 95% CI 1.002-1.012; p = 0.006) were found to be independently associated with a higher risk of all-cause mortality. This correlation remained significant even after adjusting for age and sex, and other factors and comorbidities that might affect outcomes (hazard ratio: 2.708, 95% CI 1.047, 7.003, p = 0.040 and 1.007; 95% CI 1.001, 1.013, p = 0.016, respectively). Furthermore, a history of diabetes mellitus was not a significant factor influencing long-term all-cause mortality. Preoperative glucose levels were found to be independently associated with survival outcomes in patients with OVCF who underwent VP. Conversely, diabetes mellitus was not associated with long-term all-cause mortality. Our findings highlight that preoperative hyperglycemia is a risk factor for long-term mortality in this aging surgical population.

People with diabetes has an elevated risk of depression, and depression contributes to a worse prognosis for people with diabetes. Dietary antioxidants have been shown to reduce the risk of depression in the general population. Therefore, we hypothesized that dietary antioxidants would also help to reduce the risk of depression and all-cause mortality in people with prediabetes. A total of 8789 participants aged 20 years and older from the 2005-2018 National Health and Nutrition Examination Surveys who met the diagnostic criteria for prediabetes were included in our study. The associations between six dietary antioxidant intakes and the composite dietary antioxidant index (CDAI) with depression risk and all-cause mortality were assessed using weighted logistic and Cox regression. Possible nonlinear associations were further explored using restricted cubic spline. To ensure the reliability of the findings, the multiple imputations by chained equation were applied to missing covariates to avoid potential bias. Our study found that moderate dietary antioxidant intake prevents depression and improves prognosis in people with prediabetes. Moreover, a CDAI score near three allows for maximum benefit. Our findings could provide clues for early intervention in people with diabetes.

N-terminal pro-Brain-type natriuretic peptide (NT-proBNP) has a predictive value of cardiovascular disease (CVD). Pro-inflammatory diet has been proven to be related to CVD. Our study investigated whether the association between NT-proBNP and mortality differed among general U.S. adults with different dietary inflammatory index (DII) scores. This study utilized the National Health and Nutrition Examination Surveys (NHANES) database from 1999 to 2004. Non-pregnant U.S. adults aged ≥ 20 years and without CVD were included. Cox regression model and restricted cubic splines were used to investigate the associations between NT-proBNP, DII, and mortality. A total of 9788 adults were included, and 2386 all-cause deaths with 668 CVD deaths occurred over 17.08 years of follow-up. NT-proBNP was positively associated with DII scores (P < 0.001). Among subjects without CVD, elevated NT-proBNP was positively associated with an increased risk of mortality, with per unit increase in log transformed NT-proBNP, the risk of all-cause and cardiovascular mortality increased by approximately 1.40 times (HR 2.397, 95%CI 1.966-2.922, P < 0.001) and 2.89 times (HR 3.889, 95%CI 2.756-5.490, P < 0.001) after adjusting for cardiovascular risk factors, similar results were observed after adjusting DII scores. Besides, significant interaction was found between lgNT-proBNP and DII on mortality (all P for interaction < 0.05). While as the DII quartiles increased, the association between lgNT-proBNP and mortality partially weakened. Our findings reveal that the association of NT-proBNP with all-cause and cardiovascular mortality differed with different DII scores among U.S. adults without CVD. A pro-inflammatory diet may partially explain the association between NT-proBNP and mortality and warrant further study.

BACKGROUND: Inter-cycle delays to chemotherapy are often required to manage drug toxicity. The impact of delays on mortality is poorly characterised. This retrospective cohort study examined the association of treatment delay with all-cause mortality in early-stage breast cancer. METHODS: This real-world analytical study included adult women with stage 2 or 3 breast cancer receiving first-line (neo-)adjuvant chemotherapy between 01/01/2014 and 31/12/2015 in England. Inter-cycle delays > 7 days during the treatment period were calculated, and the association of treatment delay with 5-year all-cause mortality was investigated. Survival was compared between patients experiencing treatment delay and those completing treatment to schedule using landmark methodology and Kaplan-Meier (KM) estimator. Cox proportional hazards regression was used to investigate the impact of delay on survival, using inverse probability of treatment weighting to adjust for confounding variables. RESULTS: 8567 patients were included. 17 % (1448) experienced inter-cycle delay > 7 days during the treatment period. 1120 (13 %) women had died at the end of the 5-year follow up period. Median follow-up time was 5.5 years. Survival probability was significantly lower in patients experiencing treatment delay by KM estimator analysis (p < 0.0001). Cox proportional hazards regression demonstrated a significant positive association between delay and 5-year all-cause mortality (HR 1.33 95 % CI 1.12-1.61, p < 0.001). CONCLUSIONS: This is the largest study of its kind demonstrating an association between treatment delay and all-cause mortality. These findings support interventions to improve toxicity management allowing completion of chemotherapy to schedule where patients experience treatment delay due to treatment-related toxicity or hospital capacity pressures.
RESUMEN
OBJECTIVE: To investigate the relationship between C-reactive protein and albumin ratios (CAR) and all-cause and cardiovascular disease(CVD)-specific mortality in individuals with coronary heart disease(CHD). METHODS: The data from 1895 patients were extracted from the National Health and Nutrition Examination Survey (NHANES) database from 1999-2010. We used weighted COX regression analyses to explore the association between CAR, all-cause, and CVD-specific mortality. Restricted cubic spline(RCS) regression models and threshold effects analysis were used to analyze nonlinear relationships. Subgroup analyses were also performed to explore these relationships further. RESULTS: During a mean follow-up of 115.78 months, 61.48% of deaths occurred, and 21.85% were due to CVD. After adjusting for potential confounders, each 1-unit increase in CAR was associated with a 65% increase in all-cause mortality and a 67% increase in CVD-specific mortality. The RCS model revealed a non-linear association between CAR and the risk of all-cause mortality and CVD-specific mortality in CHD patients (all non-linear P < 0.001). Threshold effects analysis identified inflection points in regression models of all-cause mortality (0.04, P < 0.001) and CVD-specific mortality (0.05, P = 0.0024). The interaction tests found sex, smoking and diabetes influenced the association between CAR and all-cause mortality and sex, smoking and HF influenced its association with CVD-specific mortality (all P < 0.05). CONCLUSION: There was a nonlinear association between CAR and all-cause mortality and CVD mortality in patients with CHD, with a higher hazard ratio before the inflection point. Sex, smoking, diabetes, and HF might have an effect on the associations between CAR and death risks.

BACKGROUND: The objective of this research is to clarify the impact of periodontitis on overall and cardiovascular-related death rates among hypertensive individuals. METHOD: A total of 5665 individuals with hypertension were included from the National Health and Nutrition Examination Survey (NHANES) data spanning 2001-2004 and 2009-2014. These individuals were divided into two groups based on the presence or absence of periodontitis and further stratified by the severity of periodontitis. We employed weighted multivariate Cox proportional hazards regression and Kaplan-Meier curves (log-rank test) to evaluate the impact of periodontitis on all-cause and cardiovascular mortality. Additional analyses, including adjustments for various covariates, subgroups, and sensitivity analyses, were conducted to ensure the robustness and reliability of our results. RESULT: Over an average follow-up duration of 10.22 years, there were 1,122 all-cause and 297 cardiovascular deaths. Individuals with periodontitis exhibited an elevated risk of all-cause mortality (HR = 1.33, 95% CI 1.18-1.51; p < 0.0001) and cardiovascular mortality (HR = 1.48, 95% CI 1.15-1.89; p = 0.002). Moreover, we observed a progressive increase in both all-cause mortality and cardiovascular mortality (p for trend are both lower than 0.001) and correlating with the severity of periodontitis. These associations remained consistent across various subgroup and sensitivity analyses. CONCLUSION: Our findings suggest a significant association between periodontitis and increased risks of all-cause and cardiovascular mortality among hypertensive individuals. Notably, the severity of periodontitis appears to be a critical factor, with moderate to severe cases exerting a more pronounced impact on all-cause mortality. Additionally, cardiovascular disease mortality significantlly increases in individuals with varying degrees of periodontitis.

Background: Little is known about the effect of combined exposure to different air pollutants on mortality in dialysis patients. This study aimed to investigate the association of multiple exposures to air pollutants with all-cause and cause-specific death in dialysis patients. Materials and methods: This registry-based nationwide cohort study included 90,373 adult kidney failure patients initiating maintenance dialysis between 2012 and 2020 identified from the French REIN registry. Estimated mean annual municipality levels of PM2.5, PM10, and NO2 between 2009 and 2020 were combined in different composite air pollution scores to estimate each participant's exposure at the residential place one to 3 years before dialysis initiation. Adjusted cause-specific Cox proportional hazard models were used to estimate hazard ratios (HRs) per interquartile range (IQR) greater air pollution score. Effect measure modification was assessed for age, sex, dialysis care model, and baseline comorbidities. Results: Higher levels of the main air pollution score were associated with a greater rate of all-cause deaths (HR, 1.082 [95% confidence interval (CI), 1.057-1.104] per IQR increase), regardless of the exposure lag. This association was also confirmed in cause-specific analyses, most markedly for infectious mortality (HR, 1.686 [95% CI, 1.470-1.933]). Sensitivity analyses with alternative composite air pollution scores showed consistent findings. Subgroup analyses revealed a significantly stronger association among women and fewer comorbid patients. Discussion: Long-term multiple air pollutant exposure is associated with all-cause and cause-specific mortality among patients receiving maintenance dialysis, suggesting that air pollution may be a significant contributor to the increasing trend of CKD-attributable mortality worldwide.

BACKGROUND AND AIM: Post-transplant diabetes mellitus (PTDM) is a complex condition arising from various factors including immunosuppressive medications, insulin resistance, impaired insulin secretion, and inflammatory processes. Its impact on patient and graft survival is a significant concern in kidney transplant recipients. PTDM's impact on kidney transplant recipients, including patient and graft survival and cardiovascular mortality, is a significant concern, given conflicting findings in previous studies. This meta-analysis was imperative to not only incorporate emerging evidence but also to delve into cause-specific mortality considerations. We aimed to comprehensively evaluate the association between PTDM and clinical outcomes, including all-cause and cardiovascular mortality, sepsis-related mortality, malignancy-related mortality, and graft loss, in kidney transplant recipients. MATERIALS AND METHODS: PubMed, Ovid/Medline, Web of Science, Scopus, and Cochrane Library databases were screened and studies evaluating the effect of PTDM on all-cause mortality, cardiovascular mortality, sepsis-related mortality, malignancy-related mortality, and overall graft loss in adult kidney transplant recipients were included. RESULTS: 53 studies, encompassing a total of 138,917 patients, to evaluate the association between PTDM and clinical outcomes were included. Our analysis revealed a significant increase in all-cause mortality (RR 1.70, 95% CI 1.53 to 1.89, P<0.001) and cardiovascular mortality (RR 1.86, 95% CI 1.36 to 2.54, P<0.001) among individuals with PTDM. Moreover, PTDM was associated with a higher risk of sepsis-related mortality (RR 1.96, 95% CI 1.51 to 2.54, P<0.001) but showed no significant association with malignancy-related mortality (RR 1.20, 95% CI 0.76 to 1.88). Additionally, PTDM was linked to an increased risk of overall graft failure (RR 1.33, 95% CI 1.16 to 1.54, P<0.001). CONCLUSION: These findings underscore the importance of comprehensive management strategies and the need for research targeting PTDM to improve outcomes in kidney transplant recipients.
RESUMEN
BACKGROUND: The impact of economic engagement on the health of cancer survivors is notable. Our study aims to explore the association between early loss of economic activity (EA) and the risk of all-cause mortality among gastric cancer survivors. METHODS: This retrospective cohort study utilized data from Korea's National Health Insurance Service, focusing on 30-59-year-old gastric cancer patients who received either surgery or endoscopic procedures from January 2009 to December 2013. The primary outcome measure was all-cause mortality. Early loss of EA was identified when a patient's insurance status shifted to dependent within one year following treatment. Adjusted hazard ratios (HRs) and 95% confidence intervals (CI) for all-cause mortality were estimated using multivariable Cox proportional hazards models, conducting separate analyses for surgical and endoscopic groups. RESULTS: Among 24,159 patients (median follow-up, 9.9 years), 2976 (12.3%) experienced all-cause mortality. Specifically, 2835 of these deaths occurred in patients who underwent surgery, while 141 were in the endoscopic procedure group. Early loss of EA was recorded in 14.4% of the surgery group and 7.7% of the endoscopic procedure group. Adjusted HRs (95% CI) for all-cause mortality associated with early loss of EA were 1.39 (1.27-1.54) for the surgery group and 2.27 (1.46-3.52) for the endoscopic procedure group. CONCLUSIONS: This study highlights a significant association between the early loss of EA and an increased risk of all-cause mortality in those who have undergone curative treatments for gastric cancer. It underscores the crucial role of sustaining EA in enhancing the health outcomes of these survivors.
RESUMEN
AIMS: The relationship between α-Klotho (αK) and mortality is controversial and has not been examined in a large, diverse cohort. We investigated the association between serum αK protein levels with all-cause and cause-specific mortality in a cohort representative of the US population. METHODS: We used National Health and Nutrition Examination Survey (NHANES) data from 2007 to 2016. A nonlinear association between mortality and αK levels as a quadratic variable were examined using Cox proportional hazard models and competing risk models. Multivariable models were adjusted for age, gender, race, hypertension, diabetes, smoking, alcohol use, physical activity, body mass index (BMI), serum cholesterol, estimated glomerular filtration rate, highest educational status attained and family income to poverty threshold ratio. RESULTS: Of the 13 749 participants, 1569 (11%) died, 7092 (52%) were female, and 5918 (43%) were Caucasian. The mean (SD) of age was 58 (11) years, BMI 29.7 (6.7) kg/m2, and αK was 0.85 (0.31) ng/mL. In the adjusted Cox proportional hazards model with quadratic αK, we found a U-shaped relationship between all-cause mortality and αK levels (continuous αK hazard ratio [HR] = 0.56, 95% confidence interval [CI]: 0.37, 0.85; P = .007; squared-αK HR = 1.25, 95% CI: 1.11, 1.41; P < 0.001). A similar U-shaped relationship was noted between αK and cancer mortality in the adjusted Cox proportional hazards model (continuous αK HR = 0.45, 95% CI: 0.19, 1.06; P = 0.07; squared αK HR = 1.32, 95% CI: 1.07, 1.61; P = 0.009). No relationship was present with cardiovascular or other-cause mortality. CONCLUSIONS: In this large diverse cohort, we report a U-shaped relationship between αK with all-cause and cancer mortality. Further research to elucidate the underlying biological mechanism of these relationships is needed.
RESUMEN
Purpose: This study aimed to develop an integrative dynamic nomogram, including N-terminal pro-B type natural peptide (NT-proBNP) and estimated glomerular filtration rate (eGFR), for predicting the risk of all-cause mortality in HFmrEF patients. Patients and Methods: 790 HFmrEF patients were prospectively enrolled in the development cohort for the model. The least absolute shrinkage and selection operator (LASSO) regression and Random Survival Forest (RSF) were employed to select predictors for all-cause mortality. Develop a nomogram based on the Cox proportional hazard model for predicting long-term mortality (1-, 3-, and 5-year) in HFmrEF. Internal validation was conducted using Bootstrap, and the final model was validated in an external cohort of 338 consecutive adult patients. Discrimination and predictive performance were evaluated by calculating the time-dependent concordance index (C-index), area under the ROC curve (AUC), and calibration curve, with clinical value assessed via decision curve analysis (DCA). Integrated discrimination improvement (IDI) and net reclassification improvement (NRI) were used to assess the contributions of NT-proBNP and eGFR to the nomogram. Finally, develop a dynamic nomogram using the "Dynnom" package. Results: The optimal independent predictors for all-cause mortality (APSELNH: A: angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitor (ACEI/ARB/ARNI), P: percutaneous coronary intervention/coronary artery bypass graft (PCI/CABG), S: stroke, E: eGFR, L: lg of NT-proBNP, N: NYHA, H: healthcare) were incorporated into the dynamic nomogram. The C-index in the development cohort and validation cohort were 0.858 and 0.826, respectively, with AUCs exceeding 0.8, indicating good discrimination and predictive ability. DCA curves and calibration curves demonstrated clinical applicability and good consistency of the nomogram. NT-proBNP and eGFR provided significant net benefits to the nomogram. Conclusion: In this study, the dynamic APSELNH nomogram developed serves as an accessible, functional, and effective clinical decision support calculator, offering accurate prognostic assessment for patients with HFmrEF.
RESUMEN
BACKGROUND: The newly described inflammatory burden index (IBI) reflects a patient's inflammatory burden. This study aimed to estimate the association between IBI, osteoarthritis (OA), and all-cause mortality in patients with OA. METHODS: We extracted the data of adults from the National Health and Nutrition Examination Survey database between 1999 and 2018. After using appropriate survey weights to correct for sample bias, we conducted multivariate logistic regression analyses to explore the association between IBI and OA across three models: in the unadjusted model, partially adjusted model (adjusting age, sex, race, education level, marital status, PIR, BMI, smoking status, drinking status, stroke, CVD, DM, and hypertension) and fully adjusted model (which included additional variables: HBA1C, ALT, AST, BUN, TC, and HDL). And the odds ratios (OR) and 95% confidence intervals (CI) were calculated. Similarly, using comparable survey weights and covariates adjustments, we employed Cox proportional hazards regression analysis to investigate the association between IBI and all-cause mortality in the other 3 models. The Cox proportional hazards regression models were fitted to calculate the hazard ratios (HR) and 95% CI of the association between IBI and all-cause mortality. A restricted cubic spline (RCS) was used to explore the nonlinear relationships between association effects. Subgroup analysis was performed to validate the reliability of their effects. RESULTS: In total, 22,343 eligible participants were included. Multiple logistic regression models revealed that participants with the highest IBI had 2.54 times (95%CI, 2.23, 2.90)) higher risk of OA than those with the lowest IBI in Model 1, whereas the OR was 1.21 (95%CI, 1.03, 1.42) in Model 2 and 1.23 (95%CI,1.05, 1.45) in Model 3. Multiple Cox regression models showed participants with the highest IBI had 186% (95%CI, 1.50, 2.31) times risk of developing all-cause death than those with the lowest IBI in Model 1. This trend remained stable in Models 2 (HR,1.54; 95%CI,1.22, 1.95) and 3 (HR, 1.41; 95%CI, 1.10, 1.80). The RCS revealed a significant positive association between IBI and OA risk. With respect to the association between IBI and all-cause mortality, a slight decrease in mortality was observed from the lowest quartile to the second quartile of IBI, and the mortality risk increased with increasing IBI. Subgroup analyses showed that age, cardiovascular disease, and hypertension were pivotal in the association of IBI with all-cause mortality, whereas the association of IBI with OA remained stable after stratification by other factors such as sex, race, education level, marital, smoking, and drinking status, hypertension, and most serological indices. CONCLUSIONS: This study provides evidence of a positive association between IBI, OA, and all-cause mortality. IBI may be a promising signature for assessing the inflammatory burden in patients with OA, which, in turn, is conducive to precise references for high-risk population recognition, anti-inflammatory guidance, and reducing mortality intervention.

Background: Although total joint arthroplasty is the most effective procedures for end-stage arthritis, the incidence of postoperative death and complications remains high. The association of additional peripheral nerve blocks (PNBs) to routine spinal or general anesthesia with major adverse events (including mortality and complication rates) in elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) has been subject to inconclusive findings. Methods: This retrospective observational single institution study included all patients ⧠18 years undergoing their first elective THA or TKA from January 1, 2012 to December 31, 2021. A 1:2 propensity score matching (PSM) was performed to account for the baseline differences between two groups that were accepted to PNB or not. Kaplan-Meier curves were employed to estimate the effects of PNB on mortality. The associations of PNB and the complications were assessed by logistic regression models. Results: We identified 1328 patients, among whom 197 had PNB and 1131 had not. The 90-day all-cause mortality was significantly reduced in patients with PNBs (0 % vs 2.79 %, P = 0.041) after THA or TKA, when compared to the non-PNB group. PNB was also associated with a lower risk of pulmonary complications (odds ratio [OR], 0.430; 95%confidence interval [CI],0.216-0.857) and deep vein thrombosis (OR, 0.103; 95%CI, 0.011-0.954). Interpretation: The results of this observational, propensity score-matched cohort study suggested a strong association between the addition of PNBs to routine spinal or general anesthesia and decreased risks of major adverse events.
RESUMEN
Background and purpose: This study explores the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels and mortality among Parkinson's disease (PD) patients, providing evidence for the potential benefits of vitamin D (VD) supplementation. Methods: PD patients were collected from the National Health and Nutrition Examination Survey (NHANES) database from 1999 to 2020. These patients were categorized based on their serum 25(OH)D levels: deficiency, insufficiency, and sufficiency. We compared demographic information and analyzed mortality data from the National Death Index. A restricted cubic spline model assessed the nonlinear association between 25(OH)D levels and mortality, complemented by multivariable Cox regression analysis. Consistency of results was checked through subgroup analysis. Results: The study included 364 PD patients: 87 (23.9%) with VD deficiency, 121 (33.2%) with insufficiency, and 156 (42.9%) with sufficiency. Demographically, 46.4% were male, and 56% were over 65 years. The deficiency group predominantly consisted of Mexican Americans (53.1%), had lower income levels, a higher unmarried rate, and increased liver disease incidence. The analysis showed a U-shaped curve between 25(OH)D levels and mortality risk, with the lowest risk at 78.68 nmol/L (p-non-linear = 0.007, p-overall = 0.008). Kaplan-Meier analysis found the highest survival rates in patients with 25(OH)D levels between 75-100 nmol/L (p = 0.039). Compared to this group, patients with levels below 50 nmol/L had a 3.52-fold increased mortality risk (95% CI = 1.58-7.86, p = 0.002), and those above 100 nmol/L had a 2.92-fold increase (95% CI = 1.06-8.05, p = 0.038). Age-specific subgroup analysis (p = 0.009) revealed that both very low (<50 nmol/L) and high (>100 nmol/L) levels increased mortality risk in patients under 65, while levels below 75 nmol/L raised mortality risk in older patients. Conclusion: Serum 25(OH)D levels are nonlinearly linked to mortality in PD patients, with optimal survival rates occurring at 75-100 nmol/L. Deviations from this range increase the risk of death.
RESUMEN
BACKGROUND: Few studies have examined the link between systemic oxidative stress and mortality risk in diabetes and prediabetes patients. The Oxidative Balance Score (OBS) is a novel measure of systemic oxidative stress, with higher scores indicating greater antioxidant exposure. This study investigates the relationship between OBS and all-cause and cardiovascular mortality in these patients. METHODS: This study analyzed 10,591 diabetes and prediabetes patients from the 1999-2018 National Health and Nutrition Examination Survey (NHANES). The endpoints were all-cause and cardiovascular mortality, determined from the National Death Index (NDI). OBS was calculated using 20 dietary and lifestyle factors. Kaplan-Meier survival analysis, multivariable Cox regression models, restricted cubic splines (RCS), and subgroup analyses were used to assess the relationship between OBS and mortality risks. RESULTS: Over an average follow-up of 99.8 months, 2900 (26.4 %) participants died, including 765 (8.9 %) from cardiovascular diseases. Kaplan-Meier analysis showed the lowest all-cause and cardiovascular mortality in the highest OBS quartile (Q4) and the highest mortality in the lowest quartile (Q1) (p < 0.001). In the fully adjusted model, multivariable Cox regression revealed that each unit increase in OBS was linked to a 1.8 % decrease in all-cause mortality risk (HR 0.982, 95 % CI 0.976-0.987, p < 0.0001) and a 4 % decrease in cardiovascular mortality risk (HR 0.960, 95 % CI 0.949-0.970, p < 0.0001). Compared to Q1, those in Q4 had significantly lower all-cause mortality (HR 0.719, 95 % CI 0.643-0.804, p < 0.0001, p for trend <0.0001) and cardiovascular mortality (HR 0.567, 95 % CI 0.455-0.705, p < 0.0001, p for trend <0.0001). These findings were consistent across subgroups. RCS curves showed a negative correlation between OBS and both mortality types. CONCLUSION: Higher OBS is linked to reduced all-cause and cardiovascular mortality in diabetes and prediabetes patients.
RESUMEN
BACKGROUND: The American Heart Association (AHA) recently defined a new concept of cardiovascular health-Life's Essential 8 (LE8). We sought to examine whether LE8 score is associated with a risk of all-cause and cardiovascular disease (CVD)-related mortality in individuals with hypertension. METHODS: This longitudinal study analyzed data from the National Health and Nutrition Examination Survey from 2007 to 2018 in people 20 years or older with hypertension. LE8 score (range 0-100) was measured according to the AHA definition and divided into unweighted tertiles into groups T1 (< 50.00), T2 (50.00-61.25), and T3 (≥ 61.25). Primary outcomes included all-cause mortality and CVD-specific mortality. RESULTS: A total of 15,318 individuals with hypertension were included in this study, with a mean ± standard error age of 55.06 ± 0.25 years. During the median follow-up period of 76 months, 2525 all-cause mortality occurred, of which 806 were due to CVD. Compared with participants with hypertension in the T1 group, those in T2 and T3 respectively had 28% (adjusted HR = 0.72, 95% CI 0.63-0.83, P < 0.001) and 39% (adjusted HR = 0.61, 95% CI 0.52-0.72, P < 0.001) lower risk of all-cause mortality, the T2 and T3 groups were associated with 32% (adjusted HR = 0.68, 95% CI 0.53-0.88, P = 0.003) and 36% (adjusted HR = 0.64, 95% CI 0.49-0.84, P = 0.001) reduced risk of CVD mortality separately. CONCLUSIONS: A higher LE8 score is associated with a lower risk of all-cause mortality and CVD mortality, and the higher LE8 score can be maintained in the clinic to improve prognosis by modifying the diet and lifestyle habits of individuals with hypertension.

The Atherogenic Index of Plasma (AIP) is associated with coronary artery disease (CAD) and acute coronary syndrome (ACS), but the relationship between AIP and ACS in elderly patients remains unclear. We investigated the prognostic capability of AIP for in-hospital and long-term mortality in elderly patients with ACS undergoing coronary angiography (CA). We analyzed 627 patients with ACS over 75 years of age who were admitted to our clinic between April 2015 and December 2022 and underwent CA. The primary clinical endpoints were in-hospital, 30-day, 1-year, and long-term mortality. The median follow-up time was 27 months. AIP was defined as log (triglyceride/high-density lipoprotein cholesterol). In-hospital mortality rates for patients with AIP ≤.1 and AIP >.1 were 4.7% and 17.6% (P < .001), 30-day mortality rates were 8.7% and 32.2% (P = .01), 1-year mortality rates were 12.1% and 45.1% (P < .001), and long-term mortality rates were 47.3% and 67.5% (P < .001), respectively. Multivariate Cox regression analysis revealed AIP, age, left ventricle ejection fraction (LVEF), admission creatinine, and Killip ≥2 as independent predictors for long-term mortality. AIP can predict in-hospital and long-time all-cause mortality in elderly patients with ACS undergoing CA. Age, LVEF, admission creatinine, and Killip ≥2 are additional factors that predict long-term all-cause mortality.
RESUMEN
BACKGROUND: The post-discharge prognosis of patients with sepsis remains a crucial issue; however, few studies have investigated the relationship between pre-sepsis health status and subsequent prognosis in a large population. This study aimed to examine the effect of the pre-sepsis care needs level on changes in care needs and mortality in patients with sepsis 1 year post-discharge. METHODS: This was a population-based retrospective cohort study including twelve municipalities in Japan that participated in the Longevity Improvement & Fair Evidence study between April 2014 and March 2022, with a total of 1,491,608 persons. The pre-hospitalization levels of care needs (baseline) were classified from low to high, as no care needs, support level and care needs level 1, care needs levels 2-3, and care needs levels 4-5 (fully dependent). The outcomes were changes in care needs level and mortality 1 year post-discharge, assessed by baseline care needs level using Cox proportional hazard models. RESULTS: The care needs levels of 17,648 patients analyzed at baseline were as follows: no care needs, 7982 (45.2%); support level and care needs level 1, 3736 (21.2%); care needs levels 2-3, 3089 (17.5%); and care needs levels 4-5, 2841 (16.1%). At 1 year post-discharge, the distribution of care needs were as follows: no care needs, 4791 (27.1%); support level and care needs level 1, 2390 (13.5%); care needs levels 2-3, 2629 (14.9%); care needs levels 4-5, 3373 (19.1%); and death, 4465 (25.3%). Patients with higher levels of care needs exhibited an increased association of all-cause mortality 1 year post-discharge after adjusting for confounders [hazard ratios and 95% confidence intervals: support level and care needs level 1, 1.05 (0.96, 1.15); care needs levels 2-3, 1.46 (1.33, 1.60); and care needs levels 4-5, 1.92 (1.75, 2.10); P for trend < 0.001]. CONCLUSIONS: Elevated care needs and mortality were observed in patients with sepsis within 1 year post-discharge. Older patients with sepsis and higher baseline levels of care needs had a high association of all-cause mortality 1 year post-discharge.

BACKGROUND: Physical activity engagement following a cancer diagnosis is positively associated with survival, reduced risk of disease recurrence, and reduced cancer-specific and all-cause mortality. However, rates of physical activity engagement are low among individuals diagnosed with and being treated for breast cancer or prostate cancer. OBJECTIVE: The purpose of this study was to describe the systematic process of developing an e-cycling intervention aimed at increasing physical activity among individuals living with prostate cancer or breast cancer and outline the key components to be implemented. METHODS: The Medical Research Council guidance for developing complex interventions and the Behaviour Change Wheel were used to guide intervention development. Information was gathered from the literature and through discussions with end users to understand factors influencing e-cycling. These factors were mapped onto the Theoretical Domains Framework to identify potential mechanisms of action. Behavior change techniques were selected from theory and evidence to develop intervention content. Interested parties, including cycling instructors, end users, and behavior change experts, reviewed and refined the intervention. RESULTS: Anticipated barriers and facilitators to e-cycling engagement were mapped onto 11 of the 14 domains of the Theoretical Domains Framework. A total of 23 behavior change techniques were selected to target these domains over 4 one-to-one e-cycling sessions delivered by trained cycling instructors in the community. Cycling instructors were provided a 3-hour classroom training session on delivering the intervention and a 3-hour practical session with feedback. The outcome of this work is a theory and evidence-informed intervention aimed at promoting e-cycling behavior among individuals being treated for breast cancer or prostate cancer, which is currently being implemented and evaluated. CONCLUSIONS: Transparent intervention development and reporting of content is important for comprehensively examining intervention implementation. The implementation of this intervention package is currently being evaluated in a pilot randomized controlled trial. If the intervention is found to be effective and the content and delivery are acceptable, this intervention will form a basis for the development of e-cycling interventions in other survivors of cancer.

RESUMEN
BACKGROUND: There were limited data investigating platelet indices in predicting peritoneal dialysis (PD) outcomes on comorbidities. The aim of this study was to evaluate the association between platelet indices and new-onset comorbidity and all-cause mortality in PD patients. METHODS: A single-center, retrospective observational cohort study was conducted in incident PD patients from 28 December 2011 to 24 January 2018, and followed up until 31 December 2022. Time to the first new-onset cardiovascular disease (CVD) and time to the first new-onset infection event after PD were identified as the primary outcomes. All-cause mortality was identified as the secondary endpoint. The correlation between platelet indices and comorbidities and all-cause mortality were assessed by Cox model. Data of liver disease status was not collected and analyzed. Survival curves were performed by Kaplan-Meier method with log-rank tests. RESULTS: A total of 250 incident PD patients with a median follow-up of 6.79 (inter-quarter range 4.05, 8.89) years was included. A total of 81 and 139 patients experienced the first new-onset CVD and infection event respectively during the follow-up period. High mean platelet volume (MPV) was independently associated with high risk of time to the first new-onset CVD (HR 1.895, 95% CI 1.174-3.058, p = 0.009) and all-cause mortality (HR 1.710, 95% CI 1.155-2.531, p = 0.007). Patients with low mean platelet volume to platelet count ratio (MPV/PC) were prone to occur the new-onset infection events (log rank 5.693, p = 0.017). Low MPV/PC (HR 0.652, 95% CI 0.459-0.924, p = 0.016) was significantly associated with the time to the first new-onset infection event on PD. CONCLUSIONS: Platelet indices were associated with the new-onset CVD, infectious comorbidities and all-cause mortality on PD. Low MPV/PC was associated with time to the first new-onset infection event in PD patients. Moreover, high MPV was associated with new-onset CVD and all-cause mortality in the incident PD patients.
