Abstract In addition to the spectrum of conditions known collectively as the Metabolic Syndrome, obesity is now recognized to be associated with increased risk of several cancers including colon, endometrial, and breast cancer. Obesity and carcinogenesis share 2 characteristics in common. On the one hand, they involve inflammatory pathways, and on the other hand, they involve dysregulated metabolism. In this review we focus on postmenopausal breast cancer and discuss the metabolic and cellular mechanisms whereby obesity and breast cancer are related. Because a majority of postmenopausal breast tumors are estrogen responsive, we include a discussion of the action of obesity-related factors on estrogen formation within the breast.

Physical activity (PA) and metabolic syndrome (MetS) have emerged as crucial factors in facilitating the incidence of postmenopausal (PM) breast cancer (BC). The association of PA, MetS and its components with PM BC was explored in this study. PRISMA guideline was followed and online databases were searched comprehensively to find relevant cohort and case-control studies until 18 February 2021 using keywords such as “physical activity”, “metabolic syndrome” and “breast cancer”. Eligible studies evaluating BC in postmenopausal women with a clear definition and measure of PA, MetS and its individual components were selected. A total of twenty-three articles related to PA and fifteen articles for MetS met the eligibility criteria and were assessed thoroughly. PA and MetS were significantly associated with PM BC. There was evidence of dose-response effect of PA and Mets on PM BC. Obesity, diabetes and dyslipidaemia were independently associated with PM BC and posed an increased risk on PM BC whereas the association of HPTN with PM BC was not prominent. Consistent and sustained long term PA throughout one’s lifetime was observed to decrease PM BC risk whereas increasing number of MetS components increased the risk of PM BC. Routine screening for PM women with ≥2 MetS components and obese or overweight women with any of the MetS components may be beneficial in early BC detection. Lifestyle modifications with emphasis on long term PA would be beneficial to public health in preventing and improving MetS outcomes as well as a primary prevention of sporadic PM BC.

Abstract We assessed the association between the Dietary inflammatory index (DII) and the development of metabolic syndrome in the elderly over 55 years in Northern China. The data of 1936 Chinese adults aged 55 and over from a community-based neurological disease cohort study from 2018 to 2019 were analyzed. Multiple logistic regression and restricted cubic splines regression were used for analysis, and social demographics, lifestyle, health-related factors were adjusted. In the fully adjusted model, the risk of metabolic syndrome increased by 1.28-fold in people with a pro-inflammatory diet. When we divide the metabolic syndrome by its components, high pro-inflammatory diet and hyperglycemia, triglycerides, hypertension, and abdominal obesity. We failed to observe a significant association between a high pro-inflammatory diet and HDL-C; However, these associations are moving in the expected direction. At the same time, the results of BMI subgroup analysis showed that with the increase of DII, obese people are at increased risk of metabolic syndrome, hyperglycemia, high triglycerides, hypertension, and abdominal obesity. Also in overweight people, the increase in DII is accompanied by an increased risk of hyperglycemia and abdominal obesity. Higher inflammatory diet is related to metabolic syndrome, hypertension, hyperglycemia, abdominal obesity, and hypertriglyceridemia. Further research is needed to confirm the role of inflammation and diet in the development of metabolic syndrome; however, it is desirable to reduce the dietary components associated with inflammation.

Objective. Breast cancer survivors are highly sedentary, overweight, or obese, which puts them at increased risk for comorbid chronic disease. We examined the prevalence of, and changes in, metabolic syndrome following 6 months of an aerobic exercise versus usual care intervention in a sample of sedentary postmenopausal breast cancer survivors.Design and Methods. 65 participants were randomized to an aerobic exercise intervention (EX) (n=35) mean BMI 30.8 (±5.9) kg/m2or usual care (UC) (n=30) mean BMI 29.4 (±7.4) kg/m2. Metabolic syndrome prevalence was determined, as well as change in criteria and overall metabolic syndrome.Results. At baseline, 55.4% of total women met the criteria for metabolic syndrome. There was no statistically significant change in metabolic syndrome when comparing EX and UC. However, adhering to the exercise intervention (at least 120 mins/week of exercise) resulted in a significant (P=.009) decrease in metabolic syndromez-score from baseline to 6 months (-0.76±0.36) when compared to those who did not adhere (0.80±0.42).Conclusions. Due to a higher prevalence of metabolic syndrome in breast cancer survivors, lifestyle interventions are needed to prevent chronic diseases associated with obesity. Increasing exercise adherence is a necessary target for further research in obese breast cancer survivors.

Objectives: The metabolic syndrome (MetS) refers to a cluster of interrelated physiological characteristics that are associ­ated with an increased risk of cardiovascular disease and diabetes. While the clinical usefulness of the MetS has been the subject of controversy for years, increasingly sophis­ticated methods are being used to measure the concept.Participants: Study of community health center patients who were not diabetic; study group was evenly divided between Black and White adults.Methods: Structural equation modeling of MetS incorporating the effects of race/eth­nicity, racial discrimination, socioeconomic position (SEP), and selected mediating variables.Main Outcome Measure: Latent MetS score and MetS status based on the five-point scale developed by the National Cholesterol Education Panel (NCEP).Results: The largest influences on latent MetS scores were SEP (negative relationship) and male gender (higher scores for men). Two mediating variables, physical activ­ity and stress-related eating, had smaller impacts. Self-reported racial discrimination was associated with cynical hostility but did not influence the MetS level among non­diabetics. Despite higher NCEP scores and MetS prevalence rates for Blacks compared with Whites, race did not have direct effect on MetS levels when adjusted for the other characteristics in our model.Conclusions: Neither race nor self-reported racial discrimination had direct effects on MetS level in our structural model. The large effects of socioeconomic position and male gender were not mediated by the other variables in the model.Ethn Dis. 2020;30(2):331-338; doi:10.18865/ ed.30.2.331

Bipolar disorder and major depression are life-shortening illnesses. Unnatural causes such as suicide and accidents account for only a portion of this premature mortality1 Research is beginning to identify that mood disordered patients have a higher incidence of metabolic syndrome, an illness characterized by dyslipidemia, impaired glucose tolerance, hypertension and obesity.2 Metabolic syndrome is associated with an increased risk for a variety of physical illnesses. Hypothesis: Never treated patients with mood disorders have preexisting elevations in the prevalence of the component variables of metabolic syndrome. Central obesity will be especially elevated, predicting increased premature mortality. Methods: We assessed never treated patients with mood disorders for metabolic syndrome and its component variables. Patients were assessed at baseline and followed up at 6-month intervals. All psychiatric pharmacotherapy was documented. Body mass index (BMI) was also obtained and the percentage of deaths attributable to overweight and obesity was calculated using the population attributable risk (PAR). [PAR= ∑[P (RR-1)/RR] Results: Prior to the initiation of treatment, patients did not differ from population norms with respect to metabolic syndrome or BMI. At 2-year follow-up, BMI had increased for unipolar patients 2.02 points and 1.92 points for bipolar patients. (p < .001) This increase in BMI predicted an increase in mortality of 19.4%. Conclusion: An increase in visceral obesity is often the first component of metabolic syndrome to appear and may indicate the initiation of this disease process prematurely in this group. The increase in BMI places patients with mood disorders at risk for premature mortality and indicates a need for early intervention. References 1.Osby U, Brandt L, Correia N, Ekbom A & Sparen P.

Aging Women

The metabolic syndrome (MetS) comprises individual components including central obesity, insulin resistance, dyslipidaemia and hypertension and it is associated with an increased risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). The menopause per se increases the incidence of MetS in aging women. The effect(s) of menopause on individual components of MetS include: i) increasing central obesity with changes in the fat tissue distribution, ii) potential increase in insulin resistance, iii) changes in serum lipid concentrations, which seem to be associated with increasing weight rather than menopause itself, and, iv) an association between menopause and hypertension, although available data are inconclusive. With regard to the consequences of MetS during menopause, there is no consistent data supporting a causal relationship between menopause and CVD. However, concomitant MetS during menopause appears to increase the risk of CVD. Furthermore, despite the data supporting the association between early menopause and increased risk of T2DM, the association between natural menopause itself and risk of T2DM is not evident. However, the presence and the severity of MetS appears to be associated with an increased risk of T2DM. Although the mechanism is not clear, surgical menopause is strongly linked with a higher incidence of MetS. Interestingly, women with polycystic ovary syndrome (PCOS) have an increased risk of MetS during their reproductive years; however, with menopausal transition, the risk of MetS becomes similar to that of non-PCOS women.

Objective: To our knowledge, no studies have yet looked at how the risk of developing breast cancer (BC) varies with changes in metabolic syndrome (MetS) status. This study aimed to investigate the association between changes in MetS and subsequent BC occurrence. Research Design and Methods: We enrolled 930,055 postmenopausal women aged 40–74 years who participated in a biennial National Health Screening Program in 2009–2010 and 2011–2012. Participants were categorized into four groups according to change in MetS status during the two-year interval screening: sustained non-MetS, transition to MetS, transition to non-MetS, and sustained MetS. We calculated multivariable-adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for BC incidence using the Cox proportional hazards models. Results: At baseline, MetS was associated with a significantly increased risk of BC (aHR 1.11, 95% CI 1.06–1.17) and so were all of its components. The risk of BC increased as the number of the components increased (aHR 1.46, 95% CI 1.26–1.61 for women with all five components). Compared to the sustained non-MetS group, the aHR (95% CI) for BC was 1.11 (1.04–1.19) in the transition to MetS group, 1.05 (0.96–1.14) in the transition to non-MetS group, and 1.18 (1.12–1.25) in the sustained MetS group. Conclusions: Significantly increased BC risk was observed in the sustained MetS and transition to MetS groups. These findings are clinically meaningful in that efforts to recover from MetS may lead to reduced risk of BC.

Abstract Background A relationship between depression and metabolic syndrome has been reported. Considering the diabesity rates effecting the small state of Malta it was considered appropriate to explore for links between these diseases, their metabolic determinants with depression. Methods A national health examination survey was conducted. A validated questionnaire note down (1) self-reported depression (2) anti-depressive medication (3) PHQ-9 depression symptoms score (&gt;5 positive for depression). Participants with the presence of one or more of these variables were labelled as having depression. Body mass index (BMI), waist circumference (WC) and blood pressure (BP) were measured. Blood testing for fasting blood glucose (FBG) and lipid profile were performed. The biochemical (FBG, Lipid profiles) and anthropometric profiles (BMI, WC, BP) of the depression population were compared to those without this disease. Univariant and multivariant binary logistic regression models were performed. Results The depression population (17.2% of the total population) had significantly higher median LDL, triglyceride (TG) and total cholesterol (TC) levels when compared to those without the disease (p = &lt;0.01). On univariant modelling each variable (LDL OR:1.15 p = 0.01; TG OR:1.16 p = 0.01; TC OR:1.64 p = &lt;0.01) showed a positive association with having depression even after adjusting for confounding factors (sex, age, education, smoking, alcohol habits). On multivariant modelling only an increase in TC was associated with increased risk of having depression (OR: 1.36 CI95%: 1.05-1.76 p = 0.02) after adjusting for confounders. Conclusions The various components of the metabolic syndrome appeared not to be associated with a diagnosis of depression. Only high cholesterol level exhibited a metabolic link with depression. Although further research is merited, it is suggested that physicians incorporate a depression screening tool as part of their consultation when examining high-risk patients. Key messages A metabolic syndrome profile is not linked with depression. A high cholesterol level is linked with depression, making these individuals susceptible to potential cardiovascular disease.

Childhood cancer survivors are highly exposed to the development of side effects after many years of cessation of anticancer treatment, including altered lipid metabolism that may result in an increased risk of overweight and metabolic syndrome. Adipocyte (A-FABP) and epidermal (E-FABP) fatty acid-binding proteins are expressed in adipocytes and are assumed to play an important role in the development of lipid disturbances leading to the onset of metabolic syndrome. The aim of this study was to investigate the association between serum A-FABP and E-FABP levels, overweight, and components of the metabolic syndrome in acute lymphoblastic leukemia survivors. Sixty-two acute lymphoblastic leukemia (ALL) survivors (34 females) were included in the study. The mean age at the time of the study was 12.41 ± 4.98 years (range 4.71–23.43). Serum levels of A-FABP and E-FABP were analyzed using a commercially available ELISA kit. The ALL survivors presented statistically higher A-FABP levels in comparison with the healthy controls (25.57 ± 14.46 vs. 15.13 ± 7.61 ng/mL, p < 0.001). The subjects with body mass index (BMI) above the normal range (18 overweight, 10 obese) had a greater level of A-FABP compared to the ALL group with normal BMI (32.02 ± 17.10 vs. 20.33 ± 9.24 ng/mL, p = 0.006). Of all participants, 53.23% had at least one risk factor of metabolic syndrome; in this group, only the A-FABP level showed a statistically significant difference compared to the healthy control group (30.63 ± 15.91 vs. 15.13 ± 7.61 ng/mL, p < 0.001). The subjects with two or more metabolic risk factors (16.13%) presented higher levels of both A-FABP (33.62 ± 17.16 vs. 15.13 ± 7.61 ng/mL, p = 0.001) and E-FABP (13.37 ± 3.62 vs. 10.12 ± 3.21 ng/mL, p = 0.021) compared to the controls. Univariable regression models showed significant associations between BMI and systolic blood pressure with the A-FABP level (coeff. 1.02 and 13.74, respectively; p < 0.05). In contrast, the E-FABP level was only affected by BMI (coeff. 0.48; p < 0.01). The findings reported herein suggest that the increased levels of A-FABP and E-FABP may be involved in the pathogenesis of overweight and the onset of metabolic syndrome in acute lymphoblastic leukemia. However, further longitudinal, prospective studies of fatty acid-binding proteins and their potential role in the pathogenesis of obesity and metabolic syndrome in ALL survivors remain to be performed.
