Introduction: It remains unclear if body mass index (BMI) is correlated to the amount of cardiac adipose tissue in humans. Echocardiography is typically utilized to measure epicardial fat in live patients, but has yielded inconclusive results, as it is difficult to measure cardiac adipose tissue levels from a single location on a 1-dimensional image, as fat is not always distributed equally across the heart. Methods: Through the Ohio State Cardiac Research Tissue program, we have collected over 200 human hearts of various conditions. Multi-angle photographs are available for every heart. We developed an adipose tissue scoring system, so correlations can be drawn between the adipose tissue score (ATS), and BMI in failing and non-failing human hearts. Hearts were scored based on the multi-angle photographs. Each heart was given an atrial (AATS) and a ventricular score (VATS) ranging from 0-7, based on fat distribution and epicardial fat thickness. Nine sets of scores by individuals blinded to any patient information were averaged for each heart and the average ATS was plotted for correlation analyses against BMI and etiology. Results: A strong correlation was not apparent by plotting BMI versus VATS for all failing and non-failing hearts (R 2 = 0.011915 failing, 0.017262 non-failing). It is of interest to note that the lower right quadrant of the correlation plot is empty, indication that in patients with high BMI, the ATS was also high. However, in individuals with low BMI, there was a wide distribution of ATS. VATS and AATS are closely correlated in both failing (R 2 = 0.67082) and non-failing (R 2 = 0.84446) hearts. Conclusions: Our analysis shows that in humans, a high BMI is typically correlated with a high ATS score, but a low BMI does not necessarily correlate with a low ATS. The non-failing hearts have a stronger correlation between VATS and AATS compared to the failing hearts, suggesting that failing hearts do not always have an equal distribution of adipose tissue between the atria and ventricle. Future studies will investigate the presence of correlation between ATS with other parameters, such as age, gender, and race.

Abstract Background Obesity has been pointed out as one of the risk factors for the development in several neoplastic diseases including malignant lymphoma. However the impact of obesity on the outcome of malignant diseases is unclear. L.Weiss et al have shown that high body mass index (BMI) is a significantly better prognostic factor in diffuse large B-cell lymphoma (DLBCL) (Increased body mass index is associated with improved overall survival in diffuse large B-cell lymphoma. Annals of Oncology 2014; 25: 171-176.). We evaluated this hypothesis in Japanese patients with DLBCL. Patients and Methods We analyzed 338 patients with newly diagnosed DLBCL who received full-dose (80% or more of the prescribed dose) R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) between April 2003 and December 2009 across 7 institutes. Patients of all stages were treated 6 or 8 cycles of full-dose R-CHOP therapy. All the patients were classified into 2 groups: high BMI (≥25 kg/m2 ) or low BMI (<25 kg/m2). Results The median patient age was 65 years (19–80 years); 192 were men and 146 were women. The median BMI was 22.9 kg/m2 (14.1–40.4 kg/m2); 66 patients (19.5%) were in the high BMI group (median, 27.4 kg/m2) and 272 (80.5%) were in the low BMI group (median, 21.6 kg/m2). The median follow-up of patients who were alive (n = 271) was 67.5 months (12.6–121.8 months). The 5-year progression-free survival (PFS) and overall survival (OS) of the high versus low BMI groups were 63.9% versus 74.0% (P = 0.196) and 77.2% versus 84.2% (P = 0.230), respectively (Figure1,2). Multivariate analysis considering the sex, International Prognostic Index, B symptoms, bulky mass, and BMI showed that high BMI (≥25 kg/m2) was a significant adverse prognostic factor for both OS (hazard ratio [HR], 1.906; 95% confidence interval [CI], 1.08-3.376; P = 0.027) and PFS (HR, 1.710; 95% CI, 1.054-2.774; P = 0.030). Conclusion The results of our study indicated that high BMI was an adverse prognostic factor of DLBCL. It is necessary to investigate BMI and its influence on patient background or treatment in much more cases. Figure 1 Figure 1. Figure 2 Figure 2.

Objective.Various factors affect joint damage in rheumatoid arthritis (RA). The influence of body mass index (BMI) is not adequately known. As BMI is potentially modifiable, we studied its influence on radiological joint damage in patients with RA.Methods.Treatment-naive patients with early RA (< 24 mo) were included. Demographic data were collected along with swollen joint count (SJC), tender joint count (TJC), erythrocyte sedimentation rate (ESR), and IgM-rheumatoid factor (IgM-RF). Radiographs of hands and feet were obtained. BMI and Disease Activity Score for 28-joint count (DAS28-ESR) were calculated. Joint damage was assessed using the Simplified Erosions Narrowing Score (SENS).Results.A total of 101 patients were studied (81 women; mean age 41.91 ± 11.99 yrs). Mean disease duration was 10.77 ± 6.73 months; 55 patients (54.5%) were IgM-RF-positive. Mean BMI was 22.82 ± 4.66 kg/m2 with 24 (23.8%) patients having low, 42 (41.6%) normal, and 35 (34.7%) high BMI. Mean SENS score was 16.81 ± 11.10; mean DAS28 was 6.23 ± 0.96. Significant correlation was noted between SENS and DAS28 (r = 0.28; p < 0.005). There was significant negative correlation between BMI and SENS (r = −0.509; p < 0.0005). In patients with low BMI, mean SENS (26.62 ± 13.45) was significantly higher than in patients with normal (15.88 ± 8.38; p < 0.001) and high BMI (11.20 ± 7.32; p < 0.001). Patients with normal BMI also had significantly higher SENS scores than those with high BMI (p < 0.05). One-way ANOVA did not reveal significant differences in DAS28 between groups. SENS was significantly higher in the IgM-RF-positive group (19.55 ± 11.36) than in the IgM-RF-negative group (13.54 ± 9.94; p < 0.01); DAS28 was not different between the 2 groups (6.22 ± 0.98 vs 6.26 ± 0.96, respectively). Within the 2 IgM-RF groups, a significant negative correlation was seen between BMI and SENS. Multiple regression analysis revealed RF, DAS28, and BMI were independently associated with SENS. BMI accounted for 23.04% of the variance in SENS independent of DAS28 and IgM-RF.Conclusion.Low BMI is adversely associated with joint damage in patients with early RA.

Abstract Background Little is known about cause and intervention for alanine aminotransferase (ALT) elevation after complete viral suppression in patients with chronic hepatitis B (CHB). Methods In this prospective cohort study, patients with CHB who were treated with nucleos(t)ide analogs and maintained undetectable levels of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) for at least 6 months were enrolled. Patients were followed up at 6-month intervals, and anthropometric, biochemical, and virological assessments were performed. Results Of 1965 patients with median follow-up of 18.36 months, one third of patients experienced ALT elevation. Baseline high body mass index ([BMI] defined as ≥25 kg/m2), younger age, and liver cirrhosis independently increased the risk of longitudinal ALT elevation. At the end of follow-up, 89 (4.8%) patients reverted to low BMI, and 92 (5.0%) developed to high BMI. Compared with persistent high BMI, reversion to low BMI reduced the risk of ALT elevation (adjusted odds ratio [aOR], 0.38; 95% confidence interval [CI], 0.19–0.77); compared with persistent low BMI, onset of high BMI increased the risk of ALT elevation (aOR, 1.78; 95% CI, 1.02–3.11). Conclusions High BMI is an independent predictor for ALT elevation after complete HBV DNA suppression. Improvement of BMI may have a beneficial effect on ALT normalization and even long-term outcomes.

Abstract AIM: This study was designed to investigate the prognostic effect of preoperative body mass index (BMI) for Type 2 diabetes mellitus (T2DM) patients with non-metastasis gastric cancer (GC) who underwent D2 gastrectomy.METHODS：T2DM patients with pT1-4bN0-3bM0 GC were retrospectively collected in our cancer center from January, 2000 to December, 2010. Chi-square test was used to analyze unordered categorical variables and ranked data, followed by Kaplan-Meier analysis as well as Cox regression models to detect risk factors for survival outcomes. In addition, the cut-off point was determined by the X-tile program. All analyses were carried out using survival package of R and SPSS Software. RESULTS： A total of 302 T2DM patients with pT1-4bN0-3bM0 GC were collected and analyzed. The cut-off point of BMI, identified by the X-tile program, was 19 kg/m2. Patients with low BMI (< 19 kg/m2) had a higher percentage of advanced T stage (T4a and T4b), more advanced TNM stage(stage IIIA, IIIB and IIIC), and more elevated level of serum carcinoembryonic antigen(CEA), compared to those with high BMI(>19 kg/m2)(all P < 0.05). In the low BMI subgroup, the 5-year overall survival rate was 39.02%, which was as high as 58.11% in the high BMI subgroup (P < 0.05). In the multivariate Cox regression model revealed that IIIC stage (OR= 3.101), N3b stage (OR= 3.113) were the most important prognostic indicators, followed by pretreatment BMI (OR= 2.136). CONCLUSION: Low preoperative BMI (<19 kg/m2) was a poor prognostic marker for T2DM patients with pT1-4bN0-3bM0 GC.

Abstract Aim This study was designed to investigate the prognostic effect of preoperative body mass index (BMI) for Type 2 diabetes mellitus (T2DM) patients with non-metastasis gastric cancer (GC) who underwent D2 gastrectomy. Methods T2DM patients with pT1–4bN0–3bM0 GC were retrospectively collected in Department of Gastrointestinal Surgical Oncology, Fujian Cancer Hospital & Fujian Medical University Cancer Hospital from January, 2000 to December, 2010. These patients underwent D2 radical resection of the stomach combined with regional lymphadenectomy. Chi-square test was used to analyze unordered categorical variables and ranked data, followed by Kaplan–Meier analysis as well as Cox regression models to detect risk factors for survival outcomes. In addition, the cut-off point was determined by the X-tile program. All analyses were carried out using survival package of R and SPSS Software. Results A total of 302 T2DM patients with pT1–4bN0–3bM0 GC were collected and analyzed. The cut-off points of BMI, identified by the X-tile program, was 19 kg/m2. Patients with low BMI (< 19 kg/m2) had a higher percentage of advanced T stage (T4a and T4b), more advanced TNM stage (stage IIIA, IIIB and IIIC), and more elevated level of serum carcinoembryonic antigen (CEA), compared to those with high BMI (> 19 kg/m2) (all P < 0.05). In the low BMI subgroup, the 5-year overall survival rate was 39.02%, which was as high as 58.11% in the high BMI subgroup (P < 0.05). In the multivariate Cox regression model revealed that IIIC stage (OR = 3.101), N3b stage (OR = 3.113) were the most important prognostic indicators, followed by pretreatment BMI (OR = 2.136). Conclusion Low preoperative BMI (< 19 kg/m2) was a poor prognostic marker for T2DM patients with pT1–4bN0–3bM0 GC.

AbstractObjectiveTo assess whether body mass index (BMI) has a causal effect on social and socioeconomic factors, including whether both high and low BMI can be detrimental.DesignMendelian Randomization, using genetic variants for BMI to obtain unconfounded estimates, and non-linear Mendelian Randomization.SettingUK Biobank.Participants378,244 men and women of European ancestry, mean age 57 (SD 8 years).Main outcome measuresTownsend deprivation index, income, age completed full time education, degree level education, job class, employment status, cohabiting relationship status, participation in leisure and social activities, visits from friends and family, and having someone to confide in.ResultsHigher BMI was causally associated with higher deprivation, lower income, fewer years of education, lower odds of degree-level education and skilled employment. For example, a 1 SD higher genetically-determined BMI (4.8kg/m2 in UK Biobank) was associated with £1,660 less income per annum [95%CI: £950, £2,380]. Non-linear Mendelian Randomization provided evidence that both low BMI (bottom decile, <22kg/m2) and high BMI (top seven deciles, >24.6kg/m2) can increase deprivation and reduce income. In men only, higher BMI was related to lower participation in leisure and social activities. There was no evidence of causal effects of BMI on visits from friends and family or in having someone to confide in. Non-linear Mendelian Randomization analysis showed that low BMI (bottom three deciles, <23.5kg/m2) reduces the odds of cohabiting with a partner or spouse for men, whereas high BMI (top two deciles, >30.7kg/m2) reduces the odds of cohabitation with a partner or spouse for women.ConclusionsBMI affects social and socioeconomic outcomes, with both high and low BMI being detrimental for some measures of SEP. This suggests that in addition to health benefits, maintaining healthy ranges of BMI across the population could have benefits both for individuals and society.

Abstract Background The efficacy and safety of ticagrelor versus prasugrel in patients with acute coronary syndromes (ACS) according to body mass index (BMI) remain unknown. Purpose To assess the efficacy and safety of ticagrelor versus prasugrel in patients with ACS according to BMI. Methods This post-hoc analysis of the ISAR-REACT 5 trial included 3987 patients with BMI data available. BMI was grouped in 3 categories: low (BMI&lt;25 kg/m2, n=1084), intermediate (BMI ≥25 to &lt;30 kg/m2, n=1890) and high (BMI≥30 kg/m2, n=1013). The primary endpoint was the 12-month incidence of all-cause death, myocardial infarction, or stroke. The secondary endpoint was the 12-month incidence of Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding. Results There was no significant treatment arm-by-BMI interaction regarding the primary endpoint (Pint=0.578). However, the primary endpoint occurred in 63 patients assigned to ticagrelor and 39 patients assigned to prasugrel in the low BMI group (11.7% vs. 7.5%; hazard ratio [HR]=1.62; 95% confidence interval [CI], 1.09–2.42; P=0.018), 78 patients assigned to ticagrelor and 58 patients assigned to prasugrel in the intermediate BMI group (8.3% vs. 6.2%; HR=1.36 [0.97–1.91]; P=0.076), and 43 patients assigned to ticagrelor and 37 patients assigned to prasugrel in the high BMI group (8.6% vs. 7.3%; HR=1.18 [0.76–1.84]; P=0.451). BARC type 3 to 5 bleeding events did not differ between ticagrelor and prasugrel in patients with low (6.5% vs. 6.6%), intermediate (5.6% vs. 5.0%), or high (4.4% vs. 2.8%) BMI. Conclusions BMI of patients with ACS did not impact significantly on the treatment effect of ticagrelor vs. prasugrel in terms of both efficacy and safety.

A hypothesis that goats in high body condition (BC) at kidding produce milk with lower free fatty acid (FFA) concentrations than do goats in poor condition was tested. Dry goats were measured for neck height and bodyweight 103 days prepartum, and body mass index (BMI) was calculated as bodyweight/height2, and used as a measure of BC. One-third of the goats with the highest BMI were allocated to the ‘high-BMI’ group, and the remaining two-thirds were allocated to ‘increased-BMI’ and ‘low-BMI’ groups. Until kidding, the high and low BMI groups were offered a low-energy diet, whereas the increased-BMI group was offered a high-energy diet. After parturition, all animals were offered the same diet. The goats that attained high BMI through feeding, but not those with inherent high BMI, mobilised body fat during early lactation, and increased milk yield. Milk FFA concentrations were reduced in multiparous goats, but not in yearling goats that had another genetic status and therefore were less susceptible to high milk-FFA concentrations.

Background: Mothers are the creators and sustainers of progeny. The health and wellbeing of children is intimately linked with the health, nutrition, education and well-being of their mothers because she is both the seed as well as the soil where in the baby is nurtured for 9 months. Hence the present study was conducted to determine the association between first trimester body mass index (BMI) of antenatal mothers with the mode of delivery, birth weight and APGAR scores of new born babies at birth in a tertiary care hospital.Methods: A cross-sectional study was conducted amongst 115 antenatal mothers who reported to the Labor room in a tertiary care hospital of Pune during the period of Nov. 2017 to Feb. 2018, to determine the association between first trimester body mass index (BMI) of antenatal mothers with the mode of delivery, birth weight and APGAR scores of new born babies.Results: The findings were suggestive of increased odds of APGAR of <7 at 1 min of birth among new born babies born to the study participants of low BMI group as compared to the new born babies born to the high BMI group; Increased odds of birth weight of  >3.5 kg and gestational weight gain of >14 kg and greater odds of complications among new born babies born to the study participants of high BMI group than the new born babies born to the low BMI group.Conclusions: The study concluded that birth weight of the new born babies shows a clinically significant increasing trend in association with the increasing first trimester BMI of their mothers.

Obesity has been established as a risk factor for renal cell carcinoma (RCC). Recently, studies have described obesity as a probable protecting factor in the metastatic stage of RCC. In this study, we assessed the relationship between body mass index (BMI) and overall survival in patients under systemic therapy.The correlation between BMI and overall median survival was studied in 76 patients diagnosed with metastatic RCC under systemic therapy. The groups were divided into overweight and obesity (BMI > 25 kg/m2) and underweight or normal (BMI < 25 kg/m2). Statistical analysis was performed using the Cox regression model adjusted by gender.A total of 76 patients were studied: 16 women (21%) and 60 men (79%). The median BMI was 27.96 kg/m2; 24 patients (31.6%) had low BMI and 52 (68.4%) had high BMI. Median overall survival in the group with BMI > 25 kg/m2 was 17 months (95% confidence interval [CI]: 13–34 months), while in the group with BMI ≤ 25 kg/m2, it was 14 months (95% CI: 8–20 months). When adjusted by gender, the group with BMI > 25 kg/m2 presented a hazards ratio of 0.54 (95% CI: 0.30–0.96), P = 0.044 (Log Rank).A high BMI significantly acts as a protecting factor. We observed an increased overall survival of overweight and obese patients within the context of metastatic RCC under systemic treatment. These data confirm the findings published in other studies that suggest the role of lipid metabolism in this type of tumors.
