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

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.

To observe the clinical effect of nano-carbon adsorption of 5-fluorouracil (5-FU) on Breast cancer lymph node metastasis in New Zealand rabbits. A breast cancer animal model was established by local injection of a VX2 tumor tissue suspension in thirty New Zealand rabbits. An observation group, control group A, and control group B were established using a random number table, with ten rabbits in each group. Once tumors with a diameter ≥5 mm were identified in the lymph nodes, the animals received the intervention. The observation group had nano-carbon-5-FU suspension subcutaneously injected, control group A had 5-FU subcutaneously injected through the ear margin, and control group B had 5-FU subcutaneously injected; all received a drug dose of 30 mg · kg–1. Half of the animals in the three groups were killed following treatment for thirty minutes, while the rest of the animals were killed following treatment for seven days. Tumors and lymphatic metastases were removed. Tumor and lymphatic metastasis volume were compared. H&E stained sections were used to determine the ND of tumor cells. A dTUP TUNEL assay using Terminal Deoxynucleotidyl Transferase (TdT) was used to assess tumor cell apoptosis. The expression level of casapase-3 mRNA in tumors and lymphoid tissues was determined using RT-PCR. After treatment for 30 mins, the observation group exhibited a significantly higher 5-FU concentration in lymph node metastases, and significantly lower 5-FU concentrations in plasma and tumors. Nano-carbon can increase the 5-FU concentration in tumor tissue, as well as enhance the clinical effect of drugs on lymph node metastases.

This study compares the effect of Hyalobarrier Gel and 4DryField® PH on the formation of postoperative adhesions after myomectomy in an experimental study on rabbit does. Thirty experimental animals were divided into three groups: group A – control, group B – use of 4DryField® PH, and group C – use of the Hyalobarrier Gel. A simulated myomectomy was performed in each group. The animals were euthanised 14 days after the procedure and the antiadhesive effect of the above-mentioned preparations was evaluated according to the criteria. Statistical evaluation clearly showed differences in the antiadhesive effect in the scoring systems for groups B and C compared to control group A at a high level of significance. We demonstrated an obvious, statistically confirmed antiadhesive effect of the Hyalobarrier Gel and 4DryField® PH in an experimental model of the rabbit uterus. Comparing both preparations, the Hyalobarrier Gel shows a higher level of effectiveness. Based on the results of the experiment, both preparations can be unambiguously recommended for routine practice.

e12012 Background: One of the most serious potential side effects of chemotherapy is neutropenia. Grade 3 and 4 neutropenia is especially problematic because of increased incidence of infections, hospitalization, antibiotic treatment, necessity to reduce therapy intensity. The intensity of adjuvant chemotherapy is the key to successful treatment. Dicarbamin is agent for the prevention of chemotherapy-induced neutropenia. Dicarbamin therapy decreases dystrophic changes in myeloid progenitor cells and decreases the relative number of cells with signs of apoptosis. We conducted an analysis of efficacy of dicarbamin in patients during docetaxel-based chemotherapy. Methods: Between May 2011 and July 2012, 87 patients with early breast cancer were treated with adjuvant DAC regimens (docetaxel 75 mg/m2, doxorubicin 50 mg/m2, cyclophosphamide 500 mg/m2 every 3 weeks). All patients were female. All patients were treated with these regimens without prophylactic growth factor support. 42 patients of control (group A) were not given any prophylaxis of neutropenia. 45 patients (group B) were given dicarbamin 100 mg/day on day 5 before chemotherapy administration. Treatment with dicarbamin continued for all treatment period. Neutropenia was evaluated with Common Toxicity Criteria, Version 3.0. Results: Median age was 47 (29 – 55). Grade 4 neutropenia was reported in 13 (30.9%) patients treated without dicarbamin (A) and in 8 (17.7%) patients treated with dicarbamin (B). Grade 4 neutropenia was observed in 39 cycles in group A and in 22 cycles in group B (p=0.016). The beneficial effect of dicarbamin was also demonstrated by a quick recovery of granulocytes levels than in controls. In 17 (37.7%) patients treated with dicarbamin granulocytes levels were normal all period of chemotherapy. The dose intensity of chemotherapy was more in group with dicarbamin prophilaxis. The toxicity of dicarbamin was not observed. Conclusions: Dicarbamin is an active agent for prophylaxis of neutropenia without specific toxicity. The intensity of the DAC-chemotherapy was more in group with dicarbamin prophilaxis.

This study aimed to explore the application of super paramagnetic gold magnetic nanoparticles (Au-M-NPs) in the magnetic resonance imaging (MRI) images for targeted diagnosis and treatment of breast cancer. The reducibility of ethylene glycol to ferric chloride (FeCl3) was adopted to synthesize the Au-M-NPs by solvothermal method by taking acetic acid as the base source and trisodium citrate as the stabilizer. Besides, the synthesized Au-M-NPs were applied in the MRI images for targeted therapy of breast cancer. Patients from a blank group (group A), a control group (group B), and an experimental group (group C) received the traditional clinical diagnosis treatment, MRI diagnosis, and Au-M-NPs targeted therapy with MRI in turn. The results showed that the prepared Au-M-NPs were featured with small particle size and good dispersibility, and were monodispersive after surface modification. The intraoperative blood loss of patients from group A (115.3±9.33 mL) and group B (94.6±9.72 mL) was obviously higher than the loss of group C (68.4±8.7 mL) (P < 0.05). The drainage volume of patients from group B (162.4±12.3 mL) and group C (131.9±11.8 mL) decreased sharply after surgery compared with group A (193.7±11.8 mL), and that in group C was the lowest (P < 0.05). The proportion of local recurrence in patients from group B (12.3%) and group C (6.4%) dropped steeply in contrast to the proportion of group A (13.2%) (P < 0.05). The proportion of tumor metastasis in patients from group B (11.2%) and group C (8.4%) was greatly lower than that of group A (14.8%) (P < 0.05). In conclusion, the application of Au-M-NPs in the diagnosis and treatment of breast cancer with MRI could effectively reduce the incidence of intraoperative and postoperative adverse reactions.

Abstract Study question How does embryo transfer with a low-level of mosaicism affect the success of ART programs, pregnancy, and live birth in comparison with euploid embryo transfer? Summary answer The transfer of mosaic embryos results in the delivery of a healthy baby however significantly decreases the outcome of ART programs and live birth rate. What is known already Present methods of preimplantation genetic testing of aneuploidy (PGT-A) allow detecting a mixture of euploid and aneuploid cells at the blastocyst stage with high accuracy. Such embryos are classified as mosaics with varying levels according to the guidelines of the International Society for Preimplantation Genetic Diagnosis (PGDIS). Numerous sources describe that number of mosaic embryos can vary from 4 to 22%. Several publications report that mosaic embryos can lead to successful pregnancies and healthy childbirth, but with a lower frequency and higher rates of pregnancy loss compared to euploid embryos. Nevertheless, the effect of mosaicism on ART outcomes remains controversial. Study design, size, duration It has been analyzed 2506 embryos from 648 patients undergoing the ART program with PGT-A at the Institute of Reproductive Medicine for 2018 - 2019. Embryos after PGT-A were classified as euploid, aneuploid, and having mosaicism of less than 40% as low level and more than 40% as high level following PGDIS guidelines. Patients of (group A) were transferred 467 single euploid embryos, and 43 patients (group B) underwent single low-level mosaic embryo transfer. Participants/materials, setting, methods The embryos on day 5 or 6 were graded by Gardner Scoring System. Approximately 5–10 TE cells were biopsied from good quality blastocysts and subsequently vitrified. PGT-A was performed utilizing an array comparative genomic hybridization (aCGH) (Agilent). The transfer of mosaic embryos was performed in the absence of an alternative, only after medical genetic counseling with a risk explanation and the subsequent signing of an informed agreement. Statistical tests processed by Pearson’s chi-squared test. Main results and the role of chance Of all analyzed embryos, the proportion of euploid embryos was 48.6% (n = 1002), the total number of mosaics was 18.6% (n = 384) and aneuploid ones were 32.8% (n = 676). Depending on the level of mosaicism, the ratio between embryos with low-level mosaicism (≤40%) / high-level (≥40%) was 38.3% / 61.7%, respectively. According to the study, there was a significant decrease in the indicator of clinical pregnancy rate after embryo transfer with a low-level of mosaicism of 44.1% versus 63.2% transferred euploid embryo (р&lt;0,01), however, despite an increase losses pregnancy in the group B (26.3%) there was no significant difference (p = 0.16) in comparison with the control group (15.4%). The live birth rate (LBR) significantly decreased (p &lt; 0.001) after the transfer of the mosaic embryo by 32.5%, while in the control group the indicator was 53.9%. In all cases, after the transfer of the mosaic embryo, healthy babies were born. There were 2 cases of high-level mosaic embryo transfer as a result of which pregnancy did not occur. According to the survey, about 70% of patients agree to replant mosaic embryos, 20% are ready to go to the new program, and 10% cannot make a decision. Limitations, reasons for caution The number of patients in group B was significantly lower than in group A. Not enough cases of embryo transfer with a high-level of mosaicism. Wider implications of the findings: The current study might help to develop and to select a more appropriate strategy for transfer mosaic embryos. The next series of studies should focus on obstetric and neonatal outcome data from mosaic embryo transfer to gain a better understanding of the chromosomal and physiological health of children.

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 &lt; 0.001). When compared with TyG quartile of Q1, Q4 was associated with an OR of 2.42 (1.77, 3.31), p &lt; 0.001, Q3 was associated with an OR of 1.53 (1.21, 1.93), p &lt; 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 &lt; 0.001). On univariate analysis, smoking (OR 2.15 [1.44, 3.22], p &lt; 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 &gt;8.87 (OR 3.08 [1.93, 4.93], p &lt; 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 &gt;8.87 (OR 2.93 [1.72, 4.98], p &lt; 0.001)ConclusionTyG index was associated with breast cancer in a nonlinear dose-response fashion.

Abstract Background Gastric fistulas, bleeding, and strictures are commonly reported after laparoscopic sleeve gastrectomy (LSG), that increase morbidity and hospital stay and may put the patient’s life at risk. We report our prospective evaluation of application of synthetic sealant, a modified cyanoacrylate (Glubran®2), on suture rime, associated with omentopexy, to identify results on LSG-related complications. Methods Patients were enrolled for LSG by two Bariatric Centers, with high-level activity volume. Intraoperative recorded parameters were: operative time, estimated intraoperative bleeding, conversion rate. We prospectively evaluated the presence of early complications after LSG during the follow up period. Overall complications were analyzed. Perioperative data and weight loss were also evaluated. A control group was identified for the study. Results Group A (treated with omentopexy with Glubran®2) included 96 cases. Control group included 90 consecutive patients. There were no differences among group in terms of age, sex and Body Mass Index (BMI). No patient was lost to follow-up for both groups. Overall complication rate was significantly reduced in Group A. Mean operative time and estimated bleeding did not differ from control group. We observed three postoperative leaks in Group B, while no case in Group A (not statistical significancy). We did not observe any mortality, neither reoperation. Weight loss of the cohort was similar among groups. In our series, no leaks occurred applying omentopexy with Glubran®2. Conclusion Our experience of omentopexy with a modified cyanoacrylate sealant may lead to a standardized and reproducible approach that can be safeguard for long LSG-suture rime.
