Abstract Background Triglyceride glucose-body mass index (TyG-BMI) has been proven to be a reliable substitute for insulin resistance. However, whether a causal association exists between TyG-BMI and new-onset diabetes remains uncertain. The purpose of this study was to investigate the causal association and predictive performance between TyG-BMI and diabetes. Methods A total of 116,661 subjects who underwent a physical examination were included in this study. The subjects were divided into five equal points according to the quintile of TyG-BMI, and the outcome of interest was the occurrence of diabetic events. TyG-BMI = ln [fasting plasma glucose (mg/dL) × fasting triglycerides (mg/dL)/2] × BMI. Results During the average follow-up period of 3.1 (0.95) years, 1888 men (1.61 %) and 793 women (0.68 %) were newly diagnosed with diabetes. Multivariate Cox regression analysis showed that TyG-BMI was an independent predictor of new-onset diabetes (HR 1.50 per SD increase, 95 %CI: 1.40 to 1.60, P-trend < 0.00001), and the best TyG-BMI cutoff value for predicting new-onset diabetes was 213.2966 (area under the curve 0.7741, sensitivity 72.51 %, specificity 69.54 %). Additionally, the results of subgroup analysis suggested that the risk of TyG-BMI-related diabetes in young and middle-aged people was significantly higher than that in middle-aged and elderly people, and the risk of TyG-BMI-related diabetes in non-obese people was significantly higher than that in overweight and obese people (P for interaction < 0.05). Conclusions This cohort study of the Chinese population shows that after excluding other confounding factors, there is a causal association of TyG-BMI with diabetes, and this independent association is more obvious in young, middle-aged and non-obese people.

Abstract Background Triglyceride glucose-body mass index (TyG-BMI) has been recommended as an alternative indicator of insulin resistance. However, the association between TyG-BMI and pre-diabetes remains to be elucidated. Methods More than 100,000 subjects with normal glucose at baseline received follow-up. The main outcome event of concern was pre-diabetes defined according to the diagnostic criteria recommended by the American Diabetes Association (ADA) in 2018 and the World Health Organization (WHO) in 1999. A Cox proportional hazard regression model was used to evaluate the role of TyG-BMI in identifying people at high risk of pre-diabetes. Results At a mean observation period of 3.1 years, the incidence of pre-diabetes in the cohort was 3.70 and 12.31% according to the WHO and ADA diagnostic criteria for pre-diabetes, respectively. The multivariate Cox regression analysis demonstrated that TyG-BMI was independently positively correlated with pre-diabetes, and there was a special population dependence phenomenon. Among them, non-obese people, women and people under 50 years old had a significantly higher risk of TyG-BMI-related pre-diabetes (P-interaction< 0.05). Conclusions These findings suggest that a higher TyG-BMI significantly increases an individual’s risk of pre-diabetes, and this risk is significantly higher in women, non-obese individuals, and individuals younger than 50 years of age.

BackgroundPrevious studies have demonstrated that increased body mass index (BMI) is associated with decreased mortality in hemodialysis (HD) patients. However, the association between BMI and survival has not been well established in patients undergoing peritoneal dialysis (PD). The aim of the study was to determine the association between BMI and mortality in the PD population using the Clinical Research Center (CRC) registry for end-stage renal disease (ESRD) cohort in Korea.MethodsPrevalent patients with PD were selected from the CRC registry for ESRD, a prospective cohort study on dialysis patients in Korea. Patients were categorized into four groups by quartiles of BMI. Cox regression analysis was used to calculate the adjusted hazard ratio (HR) of mortality with a BMI of quartile 2 (21.4 - 23.5 kg/m2) as the reference.ResultsA total of 900 prevalent patients undergoing PD were included. The median follow-up period was 24 months. The multivariate Cox proportional hazard model showed that the lowest quartile of BMI was associated with higher mortality (HR 3.00,95% confidence interval (CI), 1.26 - 7.15). However, the higher quartiles of BMI were not associated with mortality compared with the reference category of BMI quartile 2 (Quartile 3: HR 1.11, 95% CI, 0.43 - 2.85, Quartile 4: H R 1.64,95% CI, 0.66 - 4.06) after adjustment for clinical variables.ConclusionsLower BMI was a significant risk factor for death, but increased BMI was not associated with mortality in Korean PD patients.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Obesity is known to be risk factor for incidence of cardiovascular (CV) events. However, the association between the reduction of body mass index (BMI) and incidence of cardiovascular event is not well established in elderly Asian population. Methods From the National Health Insurance Service-Senior (≥60 years) cohort from 2002 to 2013, 13,038 participants over 75 years old without baseline comorbidities (mean age: 78.4 ± 3.2 years 5243 (40.2%) male) were included in this study. We measured the change of BMI from first to second visit for health check-up within mean 23.6 ± 5.8months of follow-up. We categorized the reduction of BMI as five group according to the amount of change in BMI in overall patients (group 1: BMI change &lt;-10%, group 2: -10%≤BMI change&lt;-3%, group 3: -3% ≤ BMI change &lt; 3%, group 4: 3% ≤BMI change &lt; 10%, group 5: 10% ≤BMI change). We investigated the influence of change in BMI on the incidence of new-onset AF, stroke, acute myocardial infarction (MI), and CV mortality Results In the overall patients, new-onset AF, stroke, acute MI, and CV death was occurred in the 494 patients (3.5%), 775 patients (5.9%), 16 patients (0.1%), and 458 patients (3.5%) respectively. The Kaplan-Meier curve showed significant cumulative incidence rate of CV death in group 1 (Log rank p &lt; 0.001). The multivariate cox regression after adjusting for compound clinical covariates showed the risk of stroke (HR 1.43, 95% CI [1.09-1.89], p = 0.01) and CV death (HR 2.06, 95% CI [1.49-2.84] were significant higher in the group 1 as compared with group 3. In the high BMI (≥25) group, the risk of AF was significant higher in the group 5 as compared with group 3 (HR 2.38, 95% CI [1.02-5.54], p = 0.04). In contrast, the risk of stroke (HR 1.70, 95% CI [1.07-2.71], p = 0.02) and CV death (HR 3.27, 95% CI [1.66-6.41], p &lt; 0.001) was significant higher in the group 1 than in group 3. Conclusions In the elderly Asian population over 75 years old, the reduction of body weight affected worse effect on the incidence of stroke and CV death in overall patient and high BMI (≥25) group. It needs careful consideration to reduce BMI in the elderly Asian population even with high BMI (≥25) for purpose of CV events.

Abstract Background Although hemodialysis (HD) adequacy, single-pool Kt/Vurea (spKt/V), is inversely correlated with body size, each is known to affect patient survival in the same direction. Therefore, we sought to examine the relationship between HD adequacy and mortality according to body mass index (BMI) in HD patients and explore a combination effect of BMI and HD adequacy on mortality risk. Methods We retrospectively reviewed patient data from the Korean Society of Nephrology registry, a nationwide database of medical records of HD patients, from January 2001 to June 2017. We included patients ≥18 years old who were receiving maintenance HD. Patients were categorized into three groups according to baseline BMI (< 20 (low), 20 to < 23 (normal), and ≥ 23 (high) kg/m2). Baseline spKt/V was divided into six categories. Results Among 18,242 patients on HD, the median follow-up duration was 5.2 (IQR, 1.9–8.9) years. Cox regression analysis showed that, compared to the reference (spKt/V 1.2–1.4), lower and higher baseline spKt/V were associated with greater and lower risks for all-cause mortality, respectively. However, among patients with high BMI (n = 5588), the association between higher spKt/V and lower all-cause mortality was attenuated in all adjusted models (Pinteraction < 0.001). Compared to patients with normal BMI and spKt/V within the target range (1.2–1.4), those with low BMI had a higher risk for all-cause mortality at all spKt/V levels. However, the gap in mortality risk became narrower for higher values of spKt/V. Compared to patients with normal BMI and spKt/V in the target range, those with high BMI and spKt/V < 1.2 were not at increased risk for mortality despite low dialysis adequacy. Conclusions The association between spKt/V and mortality in HD patients may be modified by BMI.

Η αδιπονεκτίνη είναι μια από τις κυριότερες αδιποκίνες που παράγονται από τον λιπώδη ιστό. Προηγούμενες μελέτες έδειξαν τη δυνητική χρησιμότητα της αδιπονεκτίνης ορού ως διαγνωστικού ή/και προγνωστικού βιοδείκτη σε διάφορους συμπαγείς όγκους, αλλά τα σχετικά δεδομένα για τον καρκίνο του πνεύμονα, ειδικότερα, είναι ελλιπή. Επιπρόσθετα, η διαγνωστική ή και προγνωστική αξία των επιπέδων αδιπονεκτίνης σε άλλα βιολογικά υγρά -εκτός του περιφερικού αίματος- ασθενών με καρκίνο πνεύμονα ή και με οποιαδήποτε άλλη μορφή καρκίνου, δεν έχει, απ’ όσο γνωρίζουμε, μελετηθεί. Ο πρωταρχικός σκοπός της παρούσας μελέτης ήταν η περαιτέρω διερεύνηση της δυνητικής προγνωστικής αξίας των προθεραπευτικών επιπέδων αδιπονεκτίνης στον ορό και σε δείγματα βρογχοκυψελιδικής έκπλυσης (bronchoalveolar lavage, BAL) ασθενών με μη μικροκυτταρικό καρκίνο πνεύμονα (ΜΜΚΠ) προχωρημένου σταδίου. Στον παρόν ερευνητικό έργο μελετήθηκαν προοπτικά 29 νεοδιαγνωσθέντες ασθενείς με ΜΜΚΠ σταδίου IV. Τα προθεραπευτικά επίπεδα αδιπονεκτίνης ορού και BAL μετρήθηκαν με τη χρήση ανοσοενζυμικής μεθόδου (ELISA), και, ακολούθως, συσχετίσθηκαν με δημογραφικές, κλινικές και παθολογοανατομικές παραμέτρους. Αναλυτικότερα, οι παράμετροι που αξιολογήθηκαν συμπεριελάμβαναν το φύλο, την ηλικία, το Performance Status (PS), το δείκτη μάζας σώματος (Body Mass Index, BMI), την απώλεια βάρους > 10%, καθώς και τον ιστολογικό τύπο, βαθμό διαφοροποίησης (grade) και μέγεθος του πρωτοπαθούς όγκου. Η συσχέτιση των επιπέδων αδιπονεκτίνης και των λοιπών μεταβλητών με τη συνολική επιβίωση των ασθενών αξιολογήθηκε με μονοπαραγοντική και πολυπαραγοντική ανάλυση παλινδρόμησης του Cox (univariate and multivariate Cox regression analysis).Σύμφωνα με τα αποτελέσματα της μελέτης μας, η μέση ηλικία των ασθενών ήταν 65.6 έτη (SD= 10.1 έτη), ενώ η πλειοψηφία ήταν άνδρες (24/29 περιπτώσεις, 82.8%). Ο κυρίαρχος ιστολογικός τύπος ήταν το αδενοκαρκίνωμα (18/29 περιπτώσεις, 62.1%). Η λειτουργική κατάσταση (performance status, PS) των ασθενών ήταν 0 και 1-2 σε 17/29 περιπτώσεις (58.6%) και 12/29 περιπτώσεις (41.4%), αντιστοίχως. Απώλεια βάρους μεγαλύτερη του 10% παρατηρήθηκε σε 10/29 ασθενείς (34.5%). Οι διάμεσες τιμές επιπέδων αδιπονεκτίνης σε ορό και BAL ήταν 17710 ng/ml και 911.5 ng/ml, αντιστοίχως. Δεν παρατηρήθηκαν στατιστικώς σημαντικές συσχετίσεις μεταξύ των επιπέδων αδιπονεκτίνης (τόσο στον ορό όσο και στο BAL) και των κλινικών και παθολογοανατομικών παραμέτρων που αξιολογήθηκαν. Η μονοπαραγοντική ανάλυση παλινδρόμησης του Cox έδειξε ότι τα επίπεδα αδιπονεκτίνης δεν συσχετίζονταν σε στατιστικά σημαντικό βαθμό με την επιβίωση. Ο μόνος προγνωστικός παράγοντας που αναγνωρίστηκε, τόσο στη μονοπαραγοντική όσο και στην πολυπαραγοντική ανάλυση επιβίωσης, ήταν το PS [Hazard ratio (95% Confidence Interval): 2.75 (1.17-6.46), (p=0.02)]Συμπερασματικά, τα αποτελέσματα της προοπτικής μας μελέτης απέτυχαν να αναδείξουν στατιστικά σημαντικά συσχετίσεις των επιπέδων αδιπονεκτίνης (ορού και BAL) με τη συνολική επιβίωση καθώς και με τις δημογραφικές και κλινικοπαθολογοανατομικές παραμέτρους που αξιολογήθηκαν (συμπεριλαμβανομένου του BMI και της απώλειας βάρους), σε ασθενείς με ΜΜΚΠ σταδίου IV, σε συμφωνία με τις περισσότερες προηγούμενες κλινικές παρατηρήσεις.
