Abstract Background To date, there have no study comparing the associations between TyG index and HOMA-IR on the risk of incident albuminuria. Accordingly, the objective of the present study is to use discordance analysis to evaluate the diverse associations between TyG index and HOMA-IR on the risk of incident albuminuria. Methods A community-based prospective cohort study was performed with 2446 Chinese adults. We categorized participants into 4 concordance or discordance groups. Discordance was defined as a TyG index equal to or greater than the upper quartile and HOMA-IR less than the upper quartile, or vice versa. Results During a median follow-up period of 3.9 years, 203 of 2446 participants developed incident albuminuria (8.3%). In the multivariable logistic analyses, the high TyG index tertile group was associated with a 1.71-fold (95% confidence interval (CI) 1.07–2.72) higher risk of incident albuminuria, comparing with the low tertile group. Participants in TyG (+) & HOMA-IR (−) group had a greater risk of incident albuminuria compared with those in TyG (−) & HOMA-IR (−) group after multivariate adjustment. Subgroup analyses showed that low HOMA-IR and discordantly high TyG index was closely related to a highest risk of incident albuminuria in cardiovascular metabolic disorder subjects. Conclusions Participants with a discordantly high TyG index had a significantly greater risk of incident albuminuria, especially in metabolic dysfunction subjects. The TyG index might be a better predictor of early stage of chronic kidney disease than HOMA-IR for subjects with metabolic abnormality.

AbstractPeripheral artery disease (PAD) has been shown to be linked to elevated cardiovascular risk. The novel T50 test quantifies calcification propensity of serum and has been associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD) and in the general population. This study investigated the association of calcification propensity measured by the T50 test in 287 patients with PAD without severe CKD. Major cardiovascular events (MACEs) including nonfatal stroke and nonfatal myocardial infarction and all-cause death (MACE + ) were evaluated after a median follow-up of 4 years and long-term cardiovascular and all-cause mortality after a median follow-up of 8.7 years by Kaplan–Meier and Cox regression analyses. Mean T50 time was 268 ± 63 minutes in the study cohort (age 69 ± 10 years, 32% women, 47% diabetes). Low T50 values that signify high calcification propensity were significantly associated with the occurrence of MACE+ (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.55–0.94). This association sustained multivariate adjustment for cardiovascular risk factors (CVRFs), Fontaine PAD stage, and prevalent media sclerosis (HR: 0.65; CI: 0.47–0.91). Cardiovascular mortality was significantly associated with T50 after multivariate adjustment for CVRF (HR: 0.72; CI 0.53–0.99), but not all-cause mortality (HR: 0.80; CI: 0.64–1.01). In conclusion, calcification propensity associates with MACE+ and cardiovascular mortality in patients with PAD.

Abstract   The prevalence of type 2 diabetes (T2DM) is higher in peripheral artery disease (PAD) than in coronary artery disease (CAD) patients, and PAD overall confers higher cardiovascular risk than CAD. The purpose of this study was to investigate how the incidence of major cardiovascular events compares between PAD and CAD patients when analyses are stratified by the presence of type 2 diabetes (T2DM). We prospectively recorded major cardiovascular events and death over 10.0±4.7 years in 923 patients with stable CAD, of whom 26.7% had T2DM and in 292 patients with PAD, of whom 42.1% had T2DM. Four groups were analyzed: CAD patients without diabetes (CAD/T2DM-; n=677), CAD patients with T2DM (CAD/T2DM+; n=246), PAD patients without diabetes (PAD/T2DM-; n=169) and PAD patients with T2DM (PAD/T2DM+; n=123). When compared to the incidence of MACE in CAD+/T2DM- patients (25.1%), it was significantly higher in CAD+/T2DM+ patients (35.4%; p<0.001), in PAD+/T2DM- patients (30.2%; p=0.022) and in PAD+/T2DM+ patients (47.2%; p<0.001). Patients with both PAD and T2DM in turn were at a higher risk than CAD+/T2DM+ or PAD+/T2DM- patients (p=0.001 and p<0.001, respectively). The incidence of MACE did not differ significantly between PAD+/T2DM- and CAD+/T2DM+ patients (p=0.413). Compared to patients with CAD, Cox regression analyses after multivariate adjustment showed an adjusted hazard ratio of 1.46 [1.14–1.87], p=0.002 for the presence of PAD. Conversely, T2DM increased the risk of MACE after multivariate adjustment in CAD and PAD patients (adjusted HR 1.58 [1.27–1.98], p<0.001). In conclusion, our data show that T2DM and the presence of PAD are mutually independent predictors of MACE. Patients with both PAD and T2DM are at an exceedingly high risk of MACE.

Abstract Introduction Although natriuretic peptides (NPs) are established as a biomarker of heart failure (HF), NPs have been attracting attention as a mediator in the metabolic sequences recently. On the other hand, metabolic disorders including insulin resistance have been suggested to be involved in left ventricular (LV) concentric remodeling, hinting us to the unexpected relationship among NPs, insulin resistance and LV concentric remodeling. Purpose To investigate whether the basal B-type natriuretic peptide (BNP) level is linked to insulin resistance or LV concentric remodeling in the participants independent of HF in the Japanese Arita-cho cohort study. Methods Among 1632 subjects who participated in annual health checks from 2005 to 2008 in Arita-cho, Saga, Japan as a cohort study, we studied 675 subjects without history of cardiovascular disease with LV ejection fraction≥50% and BNP level<35pg/ml (227 men; median 62 years old). Insulin resistance was assessed by homeostatic model assessment of insulin resistance (HOMA-IR) and LV geometry including LV concentric remodeling was classified based on relative wall thickness (RWT) and LV mass index from echocardiographic findings. Results The tertile levels of BNP were inversely associated with HOMA-IR (the 1st tertile 1.33 (0.76–1.74), the 2nd tertile 1.05 (0.72–1.59), the 3rd tertile 0.95 (0.66–1.58), p=0.005); in the logistic regression analysis, the lower BNP level was related to the prevalence of insulin resistance defined as HOMA-IR≥1.37 after full multivariate adjustment (1 SD increment of BNP: adjusted odds ratio [aOR] 0.740, 95% confidence interval 0.601–0.912, P=0.005. LV concentric remodeling (RWT >0.42 and LV mass index ≤115 g/m2 in men and ≤95 g/m2 in women) was observed in 170 (25%) subjects; both low BNP level and higher insulin resistance were independently linked with LV concentric remodeling after multivariate adjustment (1 SD increment of BNP: aOR 0.714, 95% CI 0.544–0.938, p=0.015, HOMA-IR≥1.37 vs. <1.37: aOR 1.694, 95% CI 1.004–2.857, p=0.048, respectively) (Figure). Conclusions In the cohort without HF, the low BNP level was linked to insulin resistance and LV concentric remodeling independently, suggesting that the subjects with low NPs levels may cause metabolic disorders and LV morphological abnormalities.

Abstract Background There is a controversy over the association between obesity and the risk of renal events in patients with type 2 diabetes mellitus (T2DM). Furthermore, whether body weight (BW) loss following sodium glucose cotransporter 2 inhibitor (SGLT2i) treatment associated with risk of adverse renal events is unknown. Methods We used medical data from a multi-center healthcare provider in Taiwan, enrolling 8992 T2DM patients with a baseline/following-up BW data available after around 12 weeks of SGLT2i treatment, from June 1, 2016 to December 31, 2018. Patients were followed up until the occurrence of composite renal outcome (estimated glomerular filtration rate decline > 40% or end-stage kidney disease) or the end of study period, whichever occurred first. Results Participants were divided into six baseline BMI categories: < 18.5 (n = 55); 18.5–22.9 (n = 985); 23.0–24.9 (n = 1389); 25.0–29.9 (n = 3941); 30.0–34.9 (n = 1973); and ≥ 35.0 kg/m2 (n = 649). There were 38.9%, 23.5%, 24.7%, 8.4%, 2.7%, and 1.8% of patients experienced no-BW loss, initial BW loss of 0.0–2.4%, 2.5–4.9%, 5.0–7.4%, 7.5–9.9%, and ≥ 10.0%, associated with SGLT2i treatment, respectively. Compared with patients with normal BMI (BMI: 18.5–22.9 kg/m2), underweight (BMI: < 18.5 kg/m2) was associated with a higher risk of composite renal outcome (adjusted hazard ratio (aHR) [95% confidence intervals (CI)]: 2.17; [1.16–4.04]), whereas pre-obese (BMI: 25.0–29.9 kg/m2) associated with the lowest risk of composite renal outcome (0.52; [0.40–0.68]) after multivariate adjustment. Compared with those without BW loss after SGLT2i treatment, BW loss of 0.0–2.4% (0.55; [0.43–0.70]) and 2.5–4.9% (0.78; [0.63–0.98]) were associated with a lower risk, whereas BW loss ≥ 10.0% associated with a higher risk of composite renal outcome (1.61; [1.06–2.46]) after multivariate adjustment. Conclusion A modest BW loss of 0–5% associated with SGLT2i treatment was associated with a favorable renal outcome. Caution should be taken for whom are underweight at baseline or have a pronounced BW loss ≥ 10.0% associated with SGLT2i treatment, which was associated with a worse renal outcome.

Abstract Context How lymph node metastasis (LNM)-associated mortality risk is affected by BRAF V600E in papillary thyroid cancer (PTC) remains undefined. Objective To study whether BRAF V600E affected LNM-associated mortality in PTC. Design, Setting, Participants We retrospectively analyzed the effect of LNM on PTC-specific mortality with respect to BRAF status in 2638 patients (2015 females and 623 males) from 11 centers in 6 countries, with median age of 46 (IQR 35–58) years and median follow-up time of 58 (IQR 26–107) months. Results Overall, LNM showed a modest mortality risk in wild-type BRAF patients but a strong one in BRAFV600E patients. In conventional PTC (CPTC), LNM showed no increased mortality risk in wild-type BRAF patients but a robustly increased one in BRAFV600E patients; mortality rates were 2/659 (0.3%) versus 4/321 (1.2%) in non-LNM versus LNM patients (P=0.094) with wild-type BRAF, corresponding to a hazard ratio (HR) (95% CI) of 4.37 (0.80-23.89), which remained insignificant at 3.32 (0.52-21.14) after multivariate adjustment. In BRAFV600E CPTC, morality rates were 7/515 (1.4%) versus 28/363 (7.7%) in non-LNM versus LNM patients (P&lt;0.001), corresponding to HR of 4.90 (2.12-11.29) or, after multivariate adjustment, 5.76 (2.19-15.11). Adjusted mortality HR of coexisting LNM and BRAFV600E versus absence of both was 27.39 (5.15-145.80), with Kaplan-Meier analyses showing a similar synergism. Conclusions LNM-associated mortality risk is sharply differentiated by the BRAF status in PTC; in CPTC, LNM showed no increased mortality risk with wild-type BRAF but a robust one with BRAF mutation. These results have strong clinical relevance.

The relationship between eosinophils/basophils and allergic sensitization is not clear in pediatric adenotonsillar hypertrophy (ATH). The objective of this study is to investigate the relationship between eosinophil/basophil counts and peripheral specific IgE levels, and identify the common allergens in children with ATH. We initially screened 1,031 consecutive children who underwent adenotonsillectomy in our department from June 2018 to June 2019, and finally included 676 children. The eosinophil count, basophil count, and levels of specific IgE were collected. Correlations between two quantitative variables were assessed using the Pearson or Spearman coefficient. Logistic regression analyses were performed to evaluate the odds ratios (ORs) for atopy after controlling for age, sex, vitamin D, BMI, and visiting season. Both the eosinophil and basophil counts in atopic participants were significantly higher compared to non-atopic participants. The eosinophil count correlated with the levels of IgE specific to all allergens, and eosinophilia was independently associated with all tested atopy allergens other than atopy to dander after multivariate adjustment. Additionally, the basophil count correlated with the IgE levels specific to A. alternate and food mix, and basophilia was still significantly associated with atopy to food mix after multivariable adjustment. Furthermore, among allergic participants, D. farinae was the most prevalent allergen, followed by food mix, D. pteronyssinus, and A. alternata. In conclusion, eosinophils were more relevant to allergic sensitization than basophils, with eosinophils being significantly associated with all tested atopy allergens apart from dander, and basophils being associated with atopy to food mix. Furthermore, D. farinae was the most prevalent allergen and may be indicative of desensitization therapy.

Abstract Objective: We evaluate the association between the Dietary Inflammatory Index (DII) and kidney stones. Design: We performed a cross-sectional analysis using data from National Health and Nutrition Examination Survey. Dietary intake information was assessed using first 24-HR dietary recall interviews, and the Kidney Conditions was presented by questionnaire. The primary outcome was to investigate the association between DII and incidence of kidney stones, and the secondary outcome was to assess the association between DII and nephrolithiasis recurrence. Setting: The National Health and Nutrition Examination Survey (NHANES), 2007-2016. Participants: The study included 25984 NHANES participants, whose data on DII and kidney stones were available, of whom 2439 reported a history of kidney stones. Results: For the primary outcome, after fully multivariate adjustment, DII score is positively associated with the risk of kidney stones (OR = 1.07; 95% CI: [1.04–1.10]). Then, compared Q4 with Q1, a significant 38% increased likelihood of nephrolithiasis was observed. (OR=1.38; 95% CI: [1.19–1.60]). For the secondary outcome, the multivariate regression analysis showed that DII score is positively correlated with nephrolithiasis recurrence (OR=1.07; 95% CI: [1.00–1.15]). The results noted that higher DII scores (Q3 and Q4) are positively associated with a significant 48% and 61% increased risk of nephrolithiasis recurrence compared with the reference after fully multivariate adjustment. (OR=1.48; 95% CI: [1.07–2.05]; OR=1.61; 95% CI: [1.12–2.31]). Conclusions: Our findings revealed that increased intake of pro-inflammatory diet, as a higher DII score, is correlated with increased odds of kidney stones incidence and recurrence.

Objective The occurrence of pneumonia separates severe cases of COVID-19 from the majority of cases with mild disease. However, the factors determining whether or not pneumonia develops remain to be fully uncovered. We therefore explored the associations of several lifestyle factors with signs of pneumonia in COVID-19. Methods Between May and July 2020, we conducted an online survey of 201 adults in Germany who had recently gone through COVID-19, predominantly as outpatients. Of these, 165 had a PCR-based diagnosis and 36 had a retrospective diagnosis by antibody testing. The survey covered demographic information, eight lifestyle factors, comorbidities and medication use. We defined the main outcome as the presence vs. the absence of signs of pneumonia, represented by dyspnea, the requirement for oxygen therapy or intubation. Results Signs of pneumonia occurred in 39 of the 165 individuals with a PCR-based diagnosis of COVID-19 (23.6%). Among the lifestyle factors examined, only overweight/obesity was associated with signs of pneumonia (odds ratio 2.68 (1.29–5.59) p = 0.008). The observed association remained significant after multivariate adjustment, with BMI as a metric variable, and also after including the antibody-positive individuals into the analysis. Conclusions This exploratory study finds an association of overweight/obesity with signs of pneumonia in COVID-19. This finding suggests that a signal proportional to body fat mass, such as the hormone leptin, impairs the body’s ability to clear SARS-CoV-2 before pneumonia develops. This hypothesis concurs with previous work and should be investigated further to possibly reduce the proportion of severe cases of COVID-19.

Introduction: While an association between vascular disease and dementia has been identified, few studies have assessed the longitudinal relationship between aortic valve calcification (AVC) and mild cognitive impairment (MCI). We recently found AVC to be associated with increased atherosclerotic events, and we sought to determine the prognostic value of AVC derived from low dose, lung cancer screening computed tomography (LCSCT) for MCI in a moderate-to-high atherosclerotic risk cohort. Methods: This was a single site, retrospective analysis of 1401 U.S. veterans (65 years [IQI: 61, 68] years; 97% male), who underwent quantification of AVC from LCSCT indicated for smoking history. Exclusion criteria included lung cancer, prior aortic valve replacement and prior MCI diagnosis. The primary outcome was new diagnosis of MCI identified by objective testing (Mini-Mental Status Exam or Montreal Cognitive Assessment) or by ICD coding. Secondary outcome was nonfatal cerebrovascular accident (CVA). Time-to-event analysis was carried out using AVC as a continuous and a categorical variable, and multivariate adjustment included age, diabetes mellitus, glomerular filtration rate <60 mL/min, coronary artery disease, and prior CVA. Results: Over a 5-year follow up, 110 patients (8%) were newly diagnosed with MCI and 45 patients (3%) had CVA. By Cox regression, AVC was predictive of MCI (HR: 1.15 [1.07 -1.24], p<0.001) and the association remained significant after multivariate adjustment (HR: 1.09 [1.01-1.18], p=0.026). Non-zero AVC tertiles were: 0.1-115; 116-427; and ≥428 Agatston Units. AVC was associated with MCI at increasing tertiles, and after multivariate analysis, the association remained significant (HR: 1.89 [1.09-3.28], p=0.024 and HR: 1.80 [1.01-3.20], p=0.047; tertiles 2 and 3, respectively). AVC was also associated with CVA (HR: 1.17 [1.05-1.32], p=0.006); however, the association lost significance after multivariate adjustment (HR: 1.12 [0.99-1.26], p=0.080). Conclusions: To our knowledge, this is the first study demonstrating that quantification of AVC from LCSCT is predictive of MCI. The association may be in part due to atherosclerotic thromboembolic events as there was a trend toward increasing nonfatal CVA in this population.
