Instability Coefficient

In the present work, we analyzed some emotional mechanisms (emotion dysregulation—ED, negative affect—NA, and emotional vulnerability) involved in chronic diseases by means of an interdisciplinary approach. We started from the conceptualization of emotions as a complex dynamic system that can be investigated and understood within a framework inspired by Chaos Theory. An “instability coefficient” Δ was computed to analyze ED mechanisms, NA, and emotional vulnerability in different disease groups (blood cancer, breast cancer, hypertension) as well as in healthy persons. This coefficient, recently defined by our group, computes the Euclidian distance between the pairs of vectors whose components are similar or reverted items of a test measuring ED. The emotional and somatic systems were considered as two complex dynamical systems in interaction. Due to this interaction, and as a result of the laws of complexity, a small perturbation in an inner state of the emotional system could generate an important reaction in the somatic system in time. The emotional vulnerability reflected by high values of Δ was associated with the chronic disease condition. The differences between illness groups and healthy persons, as well as between the three disease groups in Δ values, were analyzed. The results showed that there were significant differences between the chronic disease groups in Δ values. The most highly significant differences in Δ values were reported between the breast cancer group and the healthy group on one hand and between the breast cancer group and the blood cancer group on the other hand. The less significant differences in Δ values were noticed between the hypertension group and the control group. Δ was significant in predicting ED and NA. Compared to the classical approaches, the original contribution of our research is that these results encourage us to propose this interdisciplinary method of assessment as a challenging, valid tool of investigation and understanding of complex phenomena that occur in the emotional and somatic system.

BACKGROUND: Carbohydrate antigens 15-3 (CA 15-3) is a conventional tumor marker in breast cancer, with low sensitivity and specificity. MicroRNA (miRNA)-21 showed its stability in circulation and could serve as powerful biomarker. The aim of this study was to evaluate miRNA-21 as breast cancer biomarker compared to CA 15-3 in Indonesian population.METHODS: Circulating plasma miRNA-21 expression was measured using qRT-PCR in 49 patients at various stages of breast cancer and 16 healthy controls. The relative expression value of miRNA-21 was calculated using 2-ΔΔCt. Meanwhile, CA 15-3 was quantified using electrochemiluminescence immunoassay (ECLIA) methods. The results of miRNA-21 and CA 15-3 plasma circulating expression were compared with controls at each stage and between stages of breast cancer.RESULTS: CA 15-3 median level in breast cancer group was 1.60 times higher compared to control group (p=0.019), 21.00 m/mL and 13.05 m/mL, respectively. Median miRNA-21 expression in breast cancer group was elevated 4.92 folds compared to control group (p=0.001), 4.43 and 0.90, respectively. There was no significant difference of CA 15-3 level between controls and all stages of breast cancer group. CA 15-3 cut-off value was 15.05 m/mL (p=0.016) with 59.2% sensitivity and 62.5% specificity. Meanwhile, there was a significant difference of miRNA-21 expression between controls and most stages of breast cancer group. Circulating miRNA-21 expression cut-off value was 2.07 (p=0.000) with 91.8% sensitivity and 87.5% specificity.CONCLUSION: Circulating miRNA-21 expression and CA 15-3 levels were significantly increased in breast cancer group compared to control group. The miRNA-21 expression increased consistently with breast cancer stage progression. miRNA-21 could serve as superior biomarker compared to CA 15-3.KEYWORDS: biomarker, breast cancer, circulating plasma, liquid biopsy, miRNA-21

BackgroundThis study aims to evaluate the association and dose-response between triglyceride-glucose (TyG) index and breast cancer.MethodThis is a multicenter case-control study conducted in six public referral hospitals in Indonesia. Cases are individuals aged 19 years or above who were diagnosed with breast cancer within 1 year of diagnosis, based on histopathology and immunohistochemistry. Controls were recruited from corresponding hospitals. TyG index was determined by the formula: ln (fasting TG [mg/dl] × fasting glucose [mg/dl]).ResultsThere were 212 participants in the breast cancer group and 212 participants in the control group. TyG index was higher in patients with breast cancer (median 8.65 [7.38, 10.9] vs. 8.30 [7.09, 10.84], p < 0.001). When compared with TyG quartile of Q1, Q4 was associated with an OR of 2.42 (1.77, 3.31), p < 0.001, Q3 was associated with an OR of 1.53 (1.21, 1.93), p < 0.001, Q2 was associated with an OR of 1.39 (1.12, 1.73), p = 0.002 for the risk of breast cancer. The dose-response relationship was nonlinear (p < 0.001). On univariate analysis, smoking (OR 2.15 [1.44, 3.22], p < 0.001), use of contraception (1.73 [1.15, 2.60], p = 0.008), alcohol consumption (OR 2.04 [0.96, 4.35], p = 0.064), and TyG Index >8.87 (OR 3.08 [1.93, 4.93], p < 0.001) were associated with risk of breast cancer. Independently associated with increased risk of breast cancer included smoking (OR 1.93 [1.23, 3.01], p = 0.004), use of contraception (OR 1.59 [1.02, 2.48], p = 0.039), and TyG Index >8.87 (OR 2.93 [1.72, 4.98], p < 0.001)ConclusionTyG index was associated with breast cancer in a nonlinear dose-response fashion.

Introduction: Adiponectin is one of the plasma protein derived from adipose tissue which has a positive effect on the metabolism of fat and lipid, resulting from its own receptors. Increase in body mass index (BMI) has a direct relationship with life length. Obesity has effects on secretion of some hormones related to adipokines. Adiponectin is an adipokine having an opposite relationship with insulin resistance and breast cancer. There is also an association between breast cancer incidence and obesity. Adiponectin level decreases in women affected by breast cancer and knowing this fact can help treat and prevent the cancer by giving adiponectin supplements. The present study compared the adiponectin levels in women affected by breast cancer and healthy females as a control group. Material and Method: In this study, 80 women with breast cancer and 80 healthy females as controls were selected and adiponectin level was compared between them. Result: Breast cancer group had higher BMI mean (28.77 ± 6.05) and lower adiponectin level in comparison to control group (p= 0.0001). Conclusion: Considering our findings, breast cancer risk is higher in women with higher BMI. Therefore, informing women in this regard could have a great effect on preventing this wide-spread disease. Taking adiponectin supplements as pills or injection could be a preventing step for breast cancer, which needs to be further cultivated in future studies.

The purpose of this study was to investigate the effects of zinc and melatonin administration on lipid peroxidation in various tissues in DMBA-induced breast cancer in female rats. A total of 42 recently weaned Wistar rats were divided into 5 groups in the study: Group 1 (Control), Group 2 (DMBA Control), Group 3 (DMBA+Zinc), Group 4 (DMBA+Melatonin), Group 5 (DMBA+Melatonin, and Zinc). MDA (malondialdehyde) and GSH (glutathione) levels were determined via the spectrophotometric method in the lung, liver, spleen, pancreas, and kidney tissue samples taken from experimental animals. The highest lung, liver, spleen, pancreas, and kidney tissue MDA levels were obtained in the DMBA-induced breast cancer group control group (G2) (p<0.05). MDA levels in DMBA+Zinc (G3), DMBA+Melatonin (G4), and DMBA+Melatonin and Zinc (G5) were significantly lower than group 2 (p<0.05). Similarly, lung, liver, spleen, pancreas, and kidney tissue GSH levels of DMBA+Zinc (G3), DMBA+Melatonin (G4), and DMBA+Melatonin and Zinc (G5) were significantly higher than that of Group 2 (p<0.05). The findings of the study indicated that increased lung, liver, spleen, pancreas, and kidney damage in DMBA-induced breast cancer is suppressed with the supplementation of zinc, melatonin, and combined zinc and melatonin.
