Paraspinous Muscle

Abstract The purpose was to examine the association of paraspinous muscle density (CT surrogate of myosteatosis) with all-cause mortality in 6803 men and 4558 women, age 60-69 years (mean age 63.6) in the National Lung Screening Trial. Our fully-automated machine learning algorithm: 1) selected the appropriate CT series, 2) chose a single CT image at the level of T12 vertebra, 3) segmented the left paraspinous muscle, and 4) recorded the muscle density in Hounsfield Units (HU). Association between baseline muscle density and all-cause mortality was determined using Cox proportional hazards models, adjusted for age, race, body mass index, pack years of smoking, and presence of diabetes, lung disease, cardiovascular disease, and cancer at enrollment. After a mean 6.44 ± 1.06 years of follow-up, 635 (9.33%) men and 265 (5.81%) women died. In men, lower muscle density on baseline CT examinations was associated with increased all-cause mortality (HR per SD = 0.90; CI = 0.83, 0.99; p=0.03). Each standard deviation (7.8 HU) decrease in muscle density was associated with a 10% increase in mortality. In women, the association did not reach significance.

<b><i>Introduction:</i></b> High risk of early death, especially contributed to cardiovascular disease, exists in patients who have chronic kidney disease (CKD). And the burden of cardiovascular disease is able to be lightened by an increase in omega-3 polyunsaturated fatty acid (omega-3 PUFA). A diet high in omega-3 PUFA in the general population is protective, although it is inconclusive about its beneficial role in the CKD population. <b><i>Methods:</i></b> From the 1999 to 2014 National Health and Nutrition Examination Surveys (NHANES), we can collect 2,990 participants who suffered from CKD, who were classified into 4 groups: &#x3c;0.86, 0.87–1.30, 1.31–1.92, and 1.93–9.65 g/day based on NHANES 24-h dietary recall questionnaire dietary omega-3 PUFA. Moreover, their mortality details were available to be obtained by linking NHANES to the National Death Index. The associations between dietary omega-3 PUFA and mortality were evaluated by constructing multivariable Cox proportional hazards models. <b><i>Results:</i></b> Over 8 years of a median follow-up, 864 deaths were recorded. The adjusted hazard ratios (95% confidence interval) for all-cause mortality of the diseased people with CKD in the 2nd (0.87–1.30 g/day), 3rd (0.87–1.30 g/day), and 4th (1.93–9.65 g/day) quartiles of dietary omega-3 PUFA were 0.94 (0.72, 1.23), 0.74 (0.54, 1.02), and 0.67 (0.48, 0.93), respectively, versus those with the lowest quartile of dietary omega-3 PUFA intake (&#x3c;0.86 g/day) (<i>p</i> for trend = 0.011). <b><i>Conclusion:</i></b> There may be a inverse relation of dietary omega-3 PUFA intake and all-cause mortality in patients with CKD. Therefore, an increase of dietary omega-3 PUFA may be encouraged to be used clinically in patients with CKD.

Abstract Background Eosinophils are traditionally known as moderators of allergic reactions; however, they have now emerged as one of the principal immune-regulating cells as well as predictors of vascular disease and mortality in the general population. Although eosinophilia has been demonstrated in hemodialysis (HD) patients, associations of eosinophil count (EOC) and its changes with mortality in HD patients are still unknown. Methods In 107 506 incident HD patients treated by a large dialysis organization during 2007–11, we examined the relationships of baseline and time-varying EOC and its changes (ΔEOC) over the first 3 months with all-cause mortality using Cox proportional hazards models with three levels of hierarchical adjustment. Results Baseline median EOC was 231 (interquartile range 155–339) cells/μL and eosinophilia (&gt;350 cells/μL) was observed in 23.4% of patients. There was a gradual increase in EOC over time after HD initiation with a median ΔEOC of 5.1 (IQR −53–199) cells/μL, which did not parallel the changes in white blood cell count. In fully adjusted models, mortality risk was highest in subjects with lower baseline and time-varying EOC (&lt;100 cells/μL) and was also slightly higher in patients with higher levels (≥550 cells/μL), resulting in a reverse J-shaped relationship. The relationship of ΔEOC with all-cause mortality risk was also a reverse J-shape where both an increase and decrease exhibited a higher mortality risk. Conclusions Both lower and higher EOCs and changes in EOC over the first 3 months after HD initiation were associated with higher all-cause mortality in incident HD patients.

BackgroundPulse blood pressure was significantly associated with all-cause mortality in middle-aged and elderly populations, but less evidence was known in young adults.ObjectiveTo assess the association of pulse pressure (PP) with all-cause mortality in young adults.MethodsThis cohort from the 1999–2006 National Health and Nutrition Examination Survey included adults aged 18–40 years. All included participants were followed up until the date of death or 31 December 2015. PP was categorised into three groups: <50, 50~60, ≥60 mm Hg. Cox proportional hazards models and subgroup analysis were performed to estimate the adjusted HRs and 95% CIs for all-cause mortality.ResultsAfter applying the exclusion criteria, 8356 participants (median age 26.63±7.01 years, 4598 women (55.03%)) were included, of which 265 (3.17%) have died during a median follow-up duration of 152.96±30.45 months. When treating PP as a continuous variable, multivariate Cox analysis showed that PP was an independent risk factor for all-cause mortality (HR 1.94, 95% CI 1.02 to 3.69; p=0.0422). When using PP<50 mm Hg as referent, from the 50~60 mm Hg to the ≥60 mm Hg group, the risks of all-cause mortality for participants with PP ranging 50–60 mm Hg or ≥60 mm Hg were 0.93 (95% CI 0.42 to 2.04) and 1.15 (95% CI 0.32 to 4.07) (P for tend was 0.959). Subgroup analysis showed that PP (HR 2.00, 95% CI 1.05 to 3.82; p=0.0360) was associated with all-cause mortality among non-hypertensive participants.ConclusionAmong young adults, higher PP was significantly associated with an increased risk of all-cause mortality, particularly among those without hypertension.

Background: The results of studies on the obesity paradox in all-cause mortality are inconsistent in patients equipped with an implantable cardioverter-defibrillator (ICD). There is a lack of relevant studies on Chinese populations with large sample size. This study aimed to investigate whether the obesity paradox in all-cause mortality is present among the Chinese population with an ICD.Methods: We conducted a retrospective analysis of multicenter data from the Study of Home Monitoring System Safety and Efficacy in Cardiac Implantable Electronic Device–implanted Patients (SUMMIT) registry in China. The outcome was all-cause mortality. The Kaplan–Meier curves, Cox proportional hazards models, and smooth curve fitting were used to investigate the association between body mass index (BMI) and all-cause mortality.Results: After inclusion and exclusion criteria, 970 patients with an ICD were enrolled. After a median follow-up of 5 years (interquartile, 4.1–6.0 years), in 213 (22.0%) patients occurred all-cause mortality. According to the Kaplan–Meier curves and multivariate Cox proportional hazards models, BMI had no significant impact on all-cause mortality, whether as a continuous variable or a categorical variable classified by various BMI categorization criteria. The fully adjusted smoothed curve fit showed a linear relationship between BMI and all-cause mortality (p-value of 0.14 for the non-linearity test), with the curve showing no statistically significant association between BMI and all-cause mortality [per 1 kg/m2 increase in BMI, hazard ratio (HR) 0.97, 95% CI 0.93–1.02, p = 0.2644].Conclusions: The obesity paradox in all-cause mortality was absent in the Chinese patients with an ICD. Prospective studies are needed to further explore this phenomenon.

Background: The elevated blood pressure (BP) at midlife or late-life is associated with cardiovascular disease and death. However, there is limited research on the association between the BP patterns from middle to old age and incident coronary heart disease (CHD) and death.Methods: A cohort of the Atherosclerosis Risk in Communities (ARIC) Study enrolled 9,829 participants who attended five in-person visits from 1987 to 2013. We determined the association of mid- to late-life BP patterns with incident CHD and all-cause mortality using multivariable-adjusted Cox proportional hazards models.Results: During a median of 16.7 years of follow-up, 3,134 deaths and 1,060 CHD events occurred. Compared with participants with midlife normotension, the adjusted hazard ratio for all-cause mortality and CHD was 1.14 (95% CI, 1.04–1.25) and 1.28 (95% CI, 1.10–1.50) in those with midlife hypertension, respectively. In further analyses, compared with a pattern of sustained normotension from mid- to late-life, there was no significant difference for the risk of incident death (HR, 1.15; 95% CI, 0.96–1.37) and CHD (HR, 1.33; 95% CI, 0.99–1.80) in participants with a pattern of midlife normotension and late-life hypertension with effective BP control. A higher risks of death and CHD were found in those with pattern of mid- to late-life hypertension with effective BP control (all-cause mortality: HR, 1.24; 95% CI, 1.08–1.43; CHD: HR, 1.65; 95% CI 1.30–2.09), pattern of midlife normotension and late-life hypertension with poor BP control (all-cause mortality: HR, 1.27; 95% CI, 1.12–1.44; CHD: HR, 1.53; 95% CI, 1.23–1.92), and pattern of mid- to late-life hypertension with poor BP control (all-cause mortality: HR, 1.49; 95% CI, 1.30–1.71; CHD: HR, 1.87; 95% CI, 1.48–2.37).Conclusions: The current findings underscore that the management of elderly hypertensive patients should not merely focus on the current BP status, but the middle-aged BP status. To achieve optimal reductions in the risk of CHD and death, it may be necessary to prevent, diagnose, and manage of hypertension throughout middle age.

Abstract Background: Hyperhomocysteinemia (HHcy) is considered a risk factor for cardiovascular disease (CVD) including chronic kidney disease (CKD). In this study, we investigated the association between serum homocysteine (Hcy) level and mortality according to the presence of CKD.Methods: Our study included data of 9,895 participants from the 1996–2016 National Health and Nutrition Examination Surveys (NHANES). Moreover, linked mortality data were included and classified into four groups according to the Hcy level. Multivariable-adjusted Cox proportional hazards models using propensity-score were used to examine dose-response associations between Hcy level and mortality.Results: Of 9,895 participants, 1032 (21.2%) participants were diagnosed with CKD. In a multivariate Cox regression analysis including all participants, Hcy level was associated with all-cause mortality, compared with the 1st quartile in Model 3 (2nd quartile: hazard ratio (HR) 1.751, 95% confidence interval (CI) 1.348-2.274, p<0.001; 3rd quartile: HR 2.220, 95% CI 1.726-2.855, p<0.001; 4th quartile: HR 3.776, 95% CI 2.952-4.830, p<0.001). In the non-CKD group, there was a significant association with all-cause mortality; however, this finding was not observed in the CKD group. The observed pattern was similar after propensity score matching. In the non-CKD group, overall mortality increased in proportion to Hcy concentration (2nd quartile: HR 2.195, 95% CI 1.299-3.709, p = 0.003; 3rd quartile: HR 2.607, 95% CI 1.570-4.332, p<0.001; 4th quartile: HR 3.720, 95% CI 2.254-6.139, p<0.001). However, the risk of all-cause mortality according to the quartile of Hcy level did not increase in the CKD groupConclusion: This study found a correlation between the Hcy level and mortality rate only in the non-CKD group. This altered risk factor patterns may be attributed to protein-energy wasting or chronic inflammation status that is accompanied by CKD.

Abstract Nonexperimental studies of the effectiveness of seasonal influenza vaccine in older adults have found 40%–60% reductions in all-cause mortality associated with vaccination, potentially due to confounding by frailty. We restricted our cohort to initiators of medications in preventive drug classes (statins, antiglaucoma drugs, and β blockers) as an approach to reducing confounding by frailty by excluding frail older adults who would not initiate use of these drugs. Using a random 20% sample of US Medicare beneficiaries, we framed our study as a series of nonrandomized “trials” comparing vaccinated beneficiaries with unvaccinated beneficiaries who had an outpatient health-care visit during the 5 influenza seasons occurring in 2010–2015. We pooled data across trials and used standardized-mortality-ratio–weighted Cox proportional hazards models to estimate the association between influenza vaccination and all-cause mortality before influenza season, expecting a null association. Weighted hazard ratios among preventive drug initiators were generally closer to the null than those in the nonrestricted cohort. Restriction of the study population to statin initiators with an uncensored approach resulted in a weighted hazard ratio of 1.00 (95% confidence interval: 0.84, 1.19), and several other hazard ratios were above 0.95. Restricting the cohort to initiators of medications in preventive drug classes can reduce confounding by frailty in this setting, but further work is required to determine the most appropriate criteria to use.

Abstract Background and Aims Prior studies showed that there is a wide variability between serial pre-dialysis measurements of serum phosphate (P). Serum P vary can be due to changes in nutritional intake, underlying bone disorders, medication use or inflammation. Various variability markers have been investigated to study the association between P variability and its association with outcomes, however, the directional trends have not been studied in depth. We aimed to study directional changes and investigated its association with outcomes. Method All adult incident HD patients treated in Fresenius Medical Care North America (FMCNA) clinics between 01/2010 and 10/2018 were included in this retrospective cohort study. Serum P levels were averaged from month 1 to 6 after the initiation of dialysis (baseline). Baseline absolute and directional range (DR) of serum P were calculated. DR of P was calculated as: P min/max (t2) – P max/min (t1), with P (t1) and P (t2) represents the timepoint when either the min P value or max P value was measured, whichever comes first, and with t2 happened after t1. It is positive when the minimum antedates the maximum, otherwise negative. All-cause mortality was recorded between months 7 and 18. Cox proportional hazards models with spline terms were applied to explore the association between absolute and DR of P and all-cause mortality. Additionally, tensor product smoothing splines were computed to study the interactions of P with absolute P and DR of P and their joint associations with outcomes, respectably. Results We studied 353,142 patients. The average age was 62.7 years, 58% were male, 64% were diabetic. Baseline P was 4.98 mg/dL, median absolute range was 2.40 mg/dL, median DR was 1.1 mg/dL. Across different levels of P, both higher levels of absolute range and DR of P were associated with higher risk of mortality (Figure 1, Figure 2). The associations even seemed stronger in patients with lower levels of serum P and with negative DR (Figure 1). Conclusion Lower levels of serum P are independently associated with an increased risk of all-cause mortality. Whereas both a positive and negative DR of P are in general associated with increased mortality, the effects of an increase are most predominant in patients with higher levels of serum P, whereas a negative directional range are most predominant in patients with low serum P. This could be explained by the fact that patients with lower levels of P are generally malnourished or inflamed, where a further reduction indicates nutritional deterioration.

Abstract Studies have shown that accounting for time-varying confounding through time-dependent Cox proportional hazards models may provide biased estimates of the causal effect of treatment when the confounder is also a mediator. We explore 2 alternative approaches to addressing this problem while examining the association between vitamin D supplementation initiated after breast cancer diagnosis and all-cause mortality. Women aged 50–80 years were identified in the National Cancer Registry Ireland (n = 5,417) between 2001 and 2011. Vitamin D use was identified from linked prescription data (n = 2,570). We sought to account for the time-varying nature of vitamin D use and time-varying confounding by bisphosphonate use using 1) marginal structural models (MSMs) and 2) G-estimation of structural nested accelerated failure-time models (SNAFTMs). Using standard adjusted Cox proportional hazards models, we found a reduction in all-cause mortality in de novo vitamin D users compared with nonusers (hazard ratio (HR) = 0.84, 95% confidence interval (CI): 0.73, 0.99). Additional adjustment for vitamin D and bisphosphonate use in the previous month reduced the hazard ratio (HR = 0.45, 95% CI: 0.33, 0.63). Results derived from MSMs (HR = 0.44, 95% CI: 0.32, 0.61) and SNAFTMs (HR = 0.45, 95% CI: 0.34, 0.52) were similar. Utilizing MSMs and SNAFTMs to account for time-varying bisphosphonate use did not alter conclusions in this example.

Abstract Objectives Exposure to cadmium (Cd), a toxic heavy metal, increases risk of numerous chronic diseases and overall mortality. However, little work has been conducted to examine the effect of Zn intake on the association between Cd burden and mortality. The aim of this study was to examine whether the association between urinary Cd concentration and all-cause and disease specific mortality differs by Zn intake level among a representative sample of the US adult population. Methods A total of 15,642 US adults aged 30 years and older in the National Health and Nutrition Examination Survey 1988–1994 and 1999–2004 were followed up through December 31, 2011. Participants’ Zn intake was assessed through 24-hour dietary recalls. The main outcomes included mortality from cardiovascular disease (CVD), cancer, and all causes. Using Cox proportional hazards models, hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for quartiles of urinary Cd, quartiles of dietary Zn, and for quartiles of urinary Cd stratified by level of dietary Zn. Results Of 5367 total deaths that occurred over a mean follow-up of 15 years, 1194 were attributed to cancer and 1677 were attributed to CVD. After adjustment for potential confounders, positive relationships were observed between urinary Cd and all-cause mortality (HR for highest vs. lowest quartile (Q4 vs. Q1): 1.38; 95% CI: 1.14–1.68; P-trend < 0.0001) and cancer mortality (HR for Q4 vs. Q1: 1.54; 95% CI: 1.05–2.27; P-trend < 0.005), but not CVD mortality (HR for Q4 vs. Q1: 1.22; 95% CI: 0.95–1.57; P-trend = 0.0502). Negative associations were observed between dietary Zn and all-cause mortality (HR for Q4 vs. Q1: 0.88; 95% CI: 0.75–1.02; P-trend < 0.05) and cancer mortality (HR for Q4 vs. Q1: 0.82; 95% CI: 0.65–1.03, P-trend < 0.05). Among the lowest tertile of Zn consumers, there was a clear positive association between urinary Cd and cancer mortality (HR for Q4 vs. Q1: 1.79; 95% CI: 1.07–3.01), however, among the highest Zn consumers, this association was somewhat diminished (HR for Q4 vs. Q1: 1.66; 95% CI: 0.80–3.41). Conclusions These findings support existing evidence that Cd burden is associated with greater mortality, and also demonstrate that greater Zn consumption is associated with reduced risk of cancer death related to Cd.
