Purpose: To evaluate the informativity of PET/CT with 18F-FES in determining estrogen receptor (ER) positivity in breast tumor tissue, as well as in regional lymph nodes or distant metastatic foci. Material and methods: The data of 30 patients who underwent PET/CT with 18F-FES performed at the stage of primary diagnosis were retrospectively analyzed. The study included patients before the start of specific treatment or on the background of neoadjuvant hormone therapy, with previously determined expression of ER according to the results of IGC. 14 patients underwent 18F-FDG PET/CT with 2–7 days difference between both PET/CT. Results: In our study, the mean SUVmax value in the primary tumor focus was 4.8, the lowest SUVmax = 1.61, and the highest SUVmax = 18.86. 18F-FES accumulation considered suspicious for metastatic lesion in axillary lymph nodes on the affected side was detected in 16 patients (56 %), mean SUVmax = 5.2, lowest SUVmax = 0.99, highest SUVmax = 11.54. On subsequent histological examination, tumor changes in axillary lymph nodes were confirmed in 16/16 patients. Conclusion: PET/CT with 18F-FES is a diagnostic method for noninvasive evaluation of ER expression in tumor foci, which can complement the data of traditional diagnostic methods and has a significant clinical potential. In our study, the results of PET/CT with 18F-FES coincided with the data of immunohistochemical study in 100 % of cases.

Background: Breast cancer (BC) occupies a leading position among my oncological diseases detected in women. Identification and search for predictors of malignant neoplasms using radiation and molecular genetic methods of research allows timely diagnosis and treatment, which improves the prognosis for breast cancer. Purpose: To identify a correlation between the molecular subtype of a breast cancer tumor at an early clinical stage and the patterns of the mammographic method. Methods: A prospective, single-center study of 363 patients diagnosed with breast cancer followed up during 2021. X-ray mammography in two projections, ultrasound-guided trephine biopsy for histological verification, and immunohistochemical (IHC) analysis to determine molecular subtypes were performed. Results: There were statistically significant differences in age between subtypes luminal A, luminal BHER2+ (p < 0.001) and triple negative (p = 0.037), luminal B, luminal BHER2+ (p = 0.001) and triple negative (p = 0.046), luminal BHER2+ and nonluminal HER2+ (p = 0.002), between nonluminal HER2+ and triple negative subtype (p = 0.034). When comparing the structure of radiological density, statistically significant differences were revealed between the subgroups luminal B, luminal BHER2+ (p = 0.010) and triple negative (p = 0.010), between luminal A and triple negative subtypes (p = 0.010). When comparing the leading mammographic symptom (p < 0.001), radiological contours of the formation (p < 0.001), the density of pathological changes (p < 0.001), the size, the newly detected pathological process (p < 0.001) statistically significant differences were also found in the subgroups. A division into groups according to the size of pathological changes within the biotypes was noted, where the aggressive phenotypes of the triple negative subtype (p = 0.001), non-luminal HER2+ (p = 0.02) and luminal B (p = 0.02), in contrast to luminal A, were manifested by a greater extent. the maximum linear size of the tumor. A symptom of nipple retraction (p = 0.048) was described, which was not characteristic of triple negative and non-luminal HER2 cancer. Conclusions: Visualization features of differences in the radiological manifestation of breast cancer of different biological subtypes up to 20 mm can be predictors of molecular subtypes. Pathological verification and IHC study remain a mandatory study, but it may be necessary to conduct an X-ray histological correlation before starting treatment and, if obvious discrepancies are detected, repeat the IHC analysis from the surgical material.

Purpose: To compare the quality of irradiation planning for patients with esophageal cancer using Clinac iX (Varian) electron accelerators with external gantry and Halcyon (Varian). Compare quantitative indicators of irradiation plans for different algorithms and versions. Material and methods: A comparative assessment of the quality of irradiation planning for 90 patients with cancer of the esophagus was carried out using the indices of dose homogeneity and conformity within the target according to the data of dose-volume histograms and dose loads on critical organs. The comparison was carried out for two models of accelerators Clinac iX (Varian) with an external gantry and tunnel type Halcyon (Varian). The results of calculations of irradiation plans using different versions and algorithms for calculating planning systems are compared. Results: A comparison of the quantitative characteristics of the exposure plans made it possible to designate the IMRT technology as the preferred one in the treatment of esophageal cancer using accelerators of both types, with external and built-in gantry. At the same time, the influence of calculation algorithms and versions of the SP on the indices of homogeneity, conformity and dose loads on critical organs is not expressed, and the calculation results are comparable within the error.

Purpose: To determine the most effective option for repeated radiation therapy in patients with continued growth of primary high-grade brain glioma, taking into account the isodose distribution during the initial course of radiation therapy. Material and methods: As a result of a retrospective analysis, the results of treatment of 100 patients with confirmed progression of high-grade glioma treated at the Chelyabinsk Regional Center for Oncology and Nuclear Medicine in the period from 2010 to 2020 were evaluated. The ratio of men and women was approximately equal (56 men and 44 women). The mean age of patients of both sexes was 47.2±11.9 years. According to the histological conclusion, patients with glioblastomas (GB) prevailed (n = 58), 42 patients were diagnosed with anaplastic astrocytoma (AA). Reoperation was performed in 26 patients. Repeated radiation therapy in an independent variant was performed in 76 patients of them: 17 patients received a course of neuronal therapy in mono mode and in 17 patients in combination with external beam radiation therapy; 23 patients underwent stereotactic radiotherapy (SRS) using the CyberKnife device; in 19 cases, remote radiation therapy. In 24 cases, a chemotherapeutic component was added in addition to radiation treatment. Results: Mean time to relapse was 23 months. The median overall survival (OS) for all patients was 35 months. (DI 26.2–43.7). Indicators of 1-year OS — 85.6 %; 3-year-old — 44.1 %, 5-year-old — 26.5 %. Depending on the type of radiation therapy: the highest progression-free survival (PFS) was found with SPLT and combined photon-neutron therapy (SPNT) as in the group of patients with recurrent EH for 15, 17, and AA 24 and 40 months, respectively. Among the patients included in our study, the majority of patients (42 people) had central recurrences (in which 95 % or more of the volume of the recurrent tumor was within 100-95 % of the initial isodose), 6 had marginal relapses (20 to 80 % of the recurrent volume is within the surface of 95 % isodose), and in 2 cases a distant recurrence was recorded (less than 20 % of the recurrent volume was within 95 % of the isodose). Distant recurrences (marginal and distant) occurred within an average of 12 months, while central recurrences were diagnosed on average 26 months after the end of the course of radiation (chemoradiation) treatment. Conclusion: Thus, when analyzing our data, in all patients with continued growth of primary high-grade brain gliomas, the method of choice for a repeated course of radiation therapy is stereotactic radiation therapy or a combined course of photon-neutron therapy, which allows to overcome the existing radioresistance.

Published: December 2023

Abstract
One alluvial grain of gold, recovered from a placer deposit in the platiniferous Au-Pd belt of Minas Gerais, at Fazenda Limeira, is distinguished by inclusions, between approximately 2 and 10 µm across, of sperrylite. Field-emission electron-microprobe analyses indicate amounts of Au of up to about 3.4 wt.% at the expense of As, without affecting Pt, the amount of which remains stoichiometric, i.e., 1.0 atom per formula unit (1.0 apfu Pt). Transmission electron microscopy of sperrylite foils, extracted by focused ion beam (FIB), shows no gold nanoparticles and thus provides evidence for Au-bearing sperrylite. The finding of Au-bearing sperrylite represents a Au-rich example of invisible Au in sulfide and arsenide minerals. Regionally, the occurrence of gold-hosted inclusions of Au-bearing sperrylite is in line with the highly oxidized fluid environment of the auriferous lodes that characterize the platiniferous Au-Pd belt of Minas Gerais.

Published: December 2023

This work aimed to evaluate the physical-chemical, microbiological and sensorial characteristics of unpeeled banana vitamin. The bananas of the cultivar Nanica (Musa acuminata Dwarf Cavendish) were in the 7th stage of maturation. The UHT whole milk used had 3% fat. The treatments were 0%, 10%, 25% and 35% addition of banana peel to the banana smoothie. The physical-chemical analyzes (acidity, pH, density, moisture, ash and fat) were carried out in triplicate, according to the methods of Adolfo Lutz. For microbiological evaluation, the analyzes of total coliforms (35ºC) and thermotolerant coliforms (45ºC) were performed using the multiple tube method and the results expressed in MPN/g. Sensory assessment was applied to 50 untrained panelists using a nine-point structured hedonic scale blind test. Data were subjected to ANOVA and Tukey's test with 5% significance to verify interactions between means. The acidity showed a statistically significant difference, with an average of 1.59%. The mean pH was 6.57 and showed statistical differences between treatments. For density, moisture, fat and ash, the averages were 1,543 g / dm3, 84.17%, 1.03% and 0.83%, respectively. Microbiological analyzes were negative for total coliforms and thermotolerant coliforms, indicating that good manufacturing practices were efficient. For sensory evaluation, the highest acceptance rate was for the treatment of 25% and 54% of the tasters consume banana smoothie at least once a month. The results of the physical-chemical analyzes allow us to infer that the peeled banana smoothie is a low-fat food, thus showing that it can be considered a low-calorie food. Microbiological analyzes showed that the vitamin was produced within good manufacturing practices, as the results for coliforms were negative for all samples. Sensory analysis allowed us to verify that the treatment with the best acceptance rate was the one with 25% of bark, but we will indicate the treatment with 35% of bark, since there was no statistical difference between the formulations in relation to acceptance.

Authors: Yoshida Luciano Hissashi Teixeira , Piedade Raul , Ecco Martios 
Published: December 2023

- Soybean yield can be affected by several factors, one of these factors is diseases such as Septoriosis and Cercosporiosis that can drastically reduce soybean yield. The objective of this study was to evaluate the efficiency of control of the associations of different fungicides with protective and resistance-inducing products in the management of Septoria glycines and Cercospora kikuchii that can affect the production components of the soybean crop. The experiment was carried out in a randomized block design (DBC) in Perobal – PR, Brazil, with 6 treatments related to the association of different fungicides with protectants and resistance inducers, applied to soybean crops with 5 replications. The first application of the treatments was performed at the V5 stage, the second application was 15 days after the first application, the third application 15 days after the second application, the fourth and last application was 15 days after the third application. The evaluations were carried out 15 days after the last application, the crop was at the R6 stage, where severity, number of pods per plant, weight of one thousand grains and yield were evaluated. The treatments that obtained the best performance for the control of septtoriosis and brown eye spot were the use of the combination of the active ingredients used in T2 (mancozeb + prothioconazole + bixafen + trifloxystrobin) and T6 (difenoconazole + propiconazole + cyproconazole + picoxystrobin + curative). The use of the curative resistance inducer containing copper and nickel (T6) has been shown to be efficient in the control of Septoriosis and Cercosporiosis and may be recommended to help in the control of these diseases, while the inducer used in the (T5) based on jasmonic and salicylic acid was not efficient.

Pseudotrombocitopenia dependiente de EDTA en un niño de 5 años: Reporte de caso
Authors: Pimentel-Morales Michael Ariel , Vega Medina Pablo Andrés , De León Augusto Gabriel , Batista del Cid Rosario del Carmen 
Published: December 2023

Introducción: La pseudotrombocitopenia dependiente del ácido etilendiaminotetraacético (PTCP-EDTA) es un fenómeno de laboratorio con una prevalencia estimada del 0,1-2% entre los pacientes hospitalizados y entre el 15-17% en los pacientes ambulatorios evaluados por trombocitopenia aislada. Se produce por cambios conformacionales a nivel de las glicoproteínas de la superficie plaquetaria que inducen la agregación de plaquetas tras la exposición al EDTA. Esta agregación da lugar a una falsa disminución del conteo de unidades totales de plaquetas al utilizar analizadores automatizados. Presentación del caso: Presentamos el caso de un paciente de 5 años que presentaba niveles bajos de plaquetas sin signos de hemorragia activa. El paciente fue ingresado en el hospital mientras se estudiaba la causa de su bajo conteo plaquetario. Para el diagnóstico de PTCP-EDTA, se realizó un frotis de sangre periférica y se compararon los niveles plaquetarios utilizando el tubo con anticoagulante de citrato. Conclusión: La PTCP-EDTA suele ser un diagnóstico que se pasa por alto y que puede dar lugar a procedimientos innecesarios y gastos adicionales para los pacientes que presentan este fenómeno in vitro.

Object of investigation – patients with ischemic heart disease, who were upon family physician monitoring at primary level of medical care and patients with ischemic heart disease, who were upon monitoring at secondary level of medical care at therapeutic department.
Оbjectives – to investigate the efficiency of the achieving of the target levels of main risk such factors as body mass index, body fat percentage, arterial pressure level, as well as low density lypoprotein cholesterol in the blood, changes of smoking rate during the treatment and changes of physical activity in patients with ischemic heart disease upon family physician monitoring and at secondary level of medical care.
As a result it was found, that upon the family physician monitoring of the patients with ischemic heart disease such risk-factors as the BMI, body fat percentage, level of physical activity after 6 weeks were modified better, than at secondary level. Upon monitoring of the patients with ischemic heart disease at secondary level of medical care such factors as blood pressure, low density lypoprotein cholesterol after 6 weeks is better modifiable, than at primary level of medical care. Such factor as smoking rate is modifiable equally bad either at primary level of medical care, or secondary level of medical care.
Conclusions. When monitoring patients with coronary heart disease, the family physician is advised to monitor more closely the achievement of target levels of blood pressure, LDL cholesterol and smoking cessation.
El fracaso de la nueva Ley General de Comunicación Social del “Plan B” en el Gobierno Obradorista
Authors: Esteinou Madrid Javier 
Published: December 2023

Para fortalecer el proyecto de gobernabilidad de la Cuarta Transformación en México el gobierno elaboró una iniciativa constitucional de reforma electoral denominada “Plan A” que fue cancelada en el Congreso de la Unión por no contar con mayoría calificada para ser aprobada. Ante ello, la presidencia de la República, con apoyo del Poder Legislativo, elaboró una segunda propuesta paralela denominada “Plan B”, para continuar con su intento de reforma electoral en el país.
Dicho “Plan B” quedó conformado por la modificación de diversas leyes entre las cuales figuró la Ley General de Comunicación Social, que conllevaba relevantes elementos anticonstitucionales en materia de comunicación política. Debido a ello, tal ley de comunicación y el “Plan B”, en conjunto, fueron anulados totalmente por la Suprema Corte de Justicia de la Nación, al ser contrarios a la Carta Magna, demostrando que la Corte es un poder republicano autónomo que puede fijar límites a los abusos cometidos por el Poder Ejecutivo y el Poder Legislativo en México.
