Fabrication of optical ceramics based on solid solution of yttrium and gadolinium sesquioxides activated by Nd3+ ions was reported. Nanopowder of Nd0.08(Y0.496Gd0.496)2O3 synthesized by laser ablation method was used as raw material. It was determined that laser-ablated nanoparticles initially have monoclinic phase transformation of which into cubic phase is started at the temperature of 1100 °C and fully completed at 1300 °C. It was found that the best transparency of samples (79.9% at the wavelength of 1060 nm) and lowest content of scattering centers of 2.7 ppm are reached by vacuum sintering of nanopowder previously calcined at 1000 °C for 3 h. A blue-shift of Nd3+ emission bands in (Y,Gd)2O3 matrix with respect to Y2O3 was observed as a result of measuring of photoluminescence spectrum. Broadening of emission bands and their partial overlap was determined suggesting the alteration of local environment of neodymium which embeds into positions of yttrium as well as gadolinium.

Stimulated Raman scattering of chirped Ti:Sapphire laser pulses in BaWO4 crystal A spectrum transformation of a chirped Ti:sapphire laser pulse stretched to 0.2 ns (with initial transform limited pulse duration of 90 fs) was experimentally studied in a tandem of BaWO4 crystals. To increase stimulated Raman scattering efficiency, broadband laser emission was used as a seed of this process. Efficiency of the Stokes component generation corresponding to the BaWO4 crystal phonon mode ν1(Ag)≈925 cm-1 reached ~ 10%. Generation of the Stokes component corresponding to the weaker phonon mode ν3(Eg)≈795 cm-1, and second Stokes components of ν1(Ag) and ν3(Eg) modes were also observed. Mechanisms reducing the stimulated Raman scattering efficiency for the ν1(Ag) mode are discussed.

The spectroscopic characteristics of mono and binuclear boron fluoride complexes of dipyrromethenes in various solvents and solid-state polymer media (films) are investigated depending on the wavelength and intensity of the exciting radiation. Along with experimental studies, quantum-chemical calculations of the electronic structure and geometry of electronically excited molecules were carried out, an interpretation of the experimental data (absorption and emission bands) was given, and a connection between the absorption spectra and the structure of bis (dipyrromethenes) and their conformations was established. The analysis of the obtained results is carried out in comparison with the modern literature data. The possibilities of practical application of the studied compounds in the development of liquid and solid-state lasers and optical solvent polarity sensor are discussed.

Theoretical calculations of excited states in complexes of gold and silver three-atom nanoclusters with carbon quantum nanodots have been performed using the M062X functional and the def2SVP {H}/def2TZVP/def2TZVPP{Ag, Au} hybrid basis set. The subsequent calculation of the excited states was performed in the approximation of the time-dependent density functional theory implemented in Gaussian09. The chromophore centers of the points were modeled by heterocyclic molecules of isoquino-diazaanthracene and benzopyrano-naphthydrine. The clusters were attached to the points by means of ethyl mercaptan and a methoxyethane bridge of various lengths. Energy transfer channels are considered depending on the mutual arrangement of energy levels of clusters and heterocycles.

Le placche ateromasiche localizzate al tratto tronco comune-succlavia destra, come marker precoce di malattia ateromasica
Authors: Marescotti Roberto
Published: January 2022

I pazienti che sviluppano una malattia cardiovascolare sono generalmente portatori, nel corso di una lunga fase preclinica, di fattori di rischio, spesso molteplici, per aterosclerosi. In questi soggetti è fondamentale una stratificazione del rischio per identificare e trattare adeguatamente coloro che andranno incontro alle manifestazioni cliniche della malattia aterosclerotica. L’ecocolordoppler dei tronchi sovraortici, che valuta la presenza di placche ateromasiche e lo spessore medio-intimale carotideo, è fondamentale nello screening di tali pazienti. L’ecocolordoppler è una metodica validata ed entrata nell’uso comune, non invasiva, facilmente ripetibile, ma che richiede un adeguato training dell’operatore per acquisire le adeguate competenze. Le nostre osservazioni richiamano l’attenzione sulla ateromasia delle arterie del distretto tronco brachiocefalico-succlavia destra, come marker precoce e predittivo del rischio, indipendente rispetto allo spessore medio-intimale carotideo.
Stories and experiences of long-distance care, the case: Israel and Mexico
Authors: Pérez Sánchez Lucía
Published: January 2022

The aim of this paper is to present the experiences of long-distance care amongst Spanish-speaking immigrant women in Israel and women living in Mexico, and to compare their experiences of care, where geographical distance is the constant variable. The research was carried out through an exploratory, transversal and non-experimental qualitative study, with non-statistical sampling, for continuous inclusion for convenience. The instrument used was an open questionnaire, based on Patton's in-depth interview structure. The main findings show the need to recognize and value the role of the long-distance caregiver in research and support approaches because of the potential impact of migration and caregivers on acculturation, stress experienced by the long-distance caregiver, the support they both may receive in the country of origin and in the country where they live, as well as the family's perception of them in terms of what caregiving means, all through critical analysis perspectives from gender, interculturality and intersectionality. Finally, the stories of the six participating women show important contributions in the care they provide to their sick family member, the primary caregiver and the rest of the family. Also, the experience of long-distance care was not determined by the length of the distance; the feelings and emotions that these women experience are the same, international migration or migration within the country were not determined.

Background. Bloodstream infections (BSI) are common after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The objective of study was to analyze pre- and post-engraftment BSI.

Materials and methods. From January 2018 till May 2021242 patients after first allo-HSCT were enrolled in the study. Median age was 35 (17–65) years. The majority of transplants were done for acute leukemias (71.9 %) in remission (91.7 %) with reduced-intensity conditioning regimens (71.5 %) and peripheral blood stem cells (74.4 %) as a graft source.

Results. Of 242 patients 95 (39.2 %) developed BSI: 79 (83.2 %) developed 1 BSI episode, 16 (16.8 %) – 2 or more. Overall 113 BSI episodes were registered: 94 (82.7 %) were caused by single microorganism, 19 (17.3 %) were polymicrobial. Probability of pre-engraftment BSI was 31.0 %, post-engraftment – 11.8 %. In total 134 microorganisms were identified: 61.2 % – gram-negative and 38.8 % – gram-positive bacteria. Gram-negative BSI rate was significantly higher during post-engraftment compared to pre-engraftment phase (57.7 % vs. 70.3 %; р = 0.008). Major risk factor for pre-engraftment BSI was mismatched unrelated allo-HSCTs (hazard ratio (HR) 2.55; 95 % confidence interval (CI) 1.32–4.91; р = 0.03), for post-engraftment BSI – secondary poor graft function (HR 21.70; 95 % CI 7.95–59.24; р <0.0001) and graft failure (HR 21.55; 95 % CI 6.27–74.08; р <0.0001), and gut graft-versus-host disease (HR 12.90; 95 % CI 5.77–28.80; р <0.0001). Thirty-day survival after each BSI episode was 90.3 % and was significantly lower in patients with post-engraftment BSI compared to pre-engraftment (71.9 % vs. 97.5 %; р <0.0001).

Conclusion. Gram-negative bacteria prevailed in the etiology of BSI. The main risk factors for pre-engraftment BSI was allo-HSCT from mismatched unrelated donors, for post-engraftment BSI – secondary poor graft function and graft failure. Post-engraftment BSI is associated with worse prognosis.
Chemotherapy limiting neutropenia. Is prevention required?
Authors: Kononenko I. B. , Snegovoy A. V. , Larionova V. B.
Published: January 2022

Neutropenia is the most common hematologic toxicity of chemotherapy. Severe and prolonged neutropenia can cause treatment delay and dose reduction. Clinical studies indicate that reducing the relative dose intensity of regimens harms treatment outcomes, especially in breast, ovarian, and pancreatic cancers. Therefore, screening of patients at high risk of neutropenia that limits planned chemotherapy is of practical importance. Unfortunately, most clinical studies indicate only the incidence of myelotoxicity with each chemotherapy regimen, and only a few have analyzed the potential risks associated with this complication. That is significant importance in highly chemotherapy-sensitive malignancies. Such patients often receive dose intense and dose dens chemotherapy. The risk of severe neutropenia in such patients and failure to adhere to planned chemotherapy may reduce the chances of cure. Currently, there is no consensus among oncologists on the management strategy for patients with neutropenia limiting chemotherapy. This topic is a worldwide discussion. The article presents scientific evidence and clinical studies dedicated to this problem. A general analysis of clinical data and experience of oncologists will allow the medical community to develop approaches to prevent this complication.

Background. Over the past 15 years, the therapeutic breakthrough in the treatment of multiple myeloma observed primarily due to the emergence of new drugs. Since the characteristic of the disease is a chronic course with consecutive periods of remissions and relapses, the search for new effective treatment options with each subsequent relapse/progression is critical to increasing the survival of patients.

Objective: to evaluate the role of pomalidomide in the treatment of relapsed/refractory multiple myeloma.

Materials and methods. The results’ analysis of using pomalidomide-based treatment (Pd (pomalidomide/dexamethasone), PVd (pomalidomide/bortezomib/dexamethasone), KPd (carfilzomib/pomalidomide/dexamethasone), IxaPd (ixazomib/pomalidomide/dexamethasone), DaraPd (daratumumab/pomalidomide/dexamethasone), IsaPd (isatuximab/ pomalidomide/dexamethasone), EloPd (elotuzumab/pomalidomide/dexamethasone)) in pretreated patients, including own data, was done. Based on the RosNIIGT FMBA of Russia, 17 patients with relapsed/refractory multiple myeloma were treated; the frequency of achieving a response and the development of adverse events was estimated; the possibility of pomalidomide dose reducing with the development of adverse events was described without an apparent decrease of effectiveness.

Results. The frequency of the overall response in using pomalidomide-based programs was 53 % (according to the world data, from 38 to 82 %). This drug is recommended for patients with multiple myeloma, even accompanied by the final stages of renal failure. The most frequent adverse event was grade III–IV neutropenia (30 % of patients). In 3 patients, the dosage of pomalidomide was adjusted with a decrease to 2 mg per day. In 2 patients, therapy was discontinued due to pulmonary embolism and bilateral pneumonia. After three courses of DaraPd, one patient achieved a complete response and underwent autologous hematopoietic stem cell transplantation.

Conclusion. Pomalidomide-based programs in patients with relapsed/refractory multiple myeloma are an effective treatment option. Using dose-adjusted pomalidomide after the occurrence of neutropenia makes it possible to normalize the neutrophils level (more than 1 × 109/l) and continue anti-myeloma therapy, preserving the therapeutic effect and in individual patients with unfavorable prognosis factors to conduct high-dose therapy followed by autologous hematopoietic stem cell transplantation.

Background. The treatment results of patients with diffuse large B-cell lymphoma (DLBCL) with c-MYC proto-oncogene and BCL2 protein positivity according to the CHOP-21 ± R scheme remain unsatisfactory, which dictates the need to intensify the therapy regimen. Due to the fact that most authors combine DH (double hit) lymphomas and DE (double expressor) lymphomas for analysis, these data do not allow forming an accurate idea of the independent significance of the phenomenon of activated transcription factor c-MYC and BCL2 protein in patients with DLBCL and the results of treatment specifically in this group. Some researchers believe that the presence of c-MYC gene aberration and BCL2 protein expression are associated with negative clinical characteristics. Nevertheless, the clinical features of this subgroup of DLBCL remain poorly understood.

The objective of the study was to analyze the incidence of c-MYC gene aberrations, BCL2 expression in DLBCL patients and to evaluate the effectiveness of intensive R + Hyper-CVAD chemotherapy regimen in this group of patients.

Materials and methods. We analyzed the data of 80 patients aged 18–65 years with a newly diagnosed DLBCL for the period from 2018 to 2020. The diagnosis was established by histological and immunohistochemical examination. The tumor stages (II–IV) were assessed according to the Ann Arbor classification; the patient’s somatic status – according to the ECOG scale with a total of no more than 3 points. To detect c-MYC gene aberrations in the tumor tissue, fluorescent in situ hybridization was performed; to determine the BCL2 protein expression and Ki-67 proliferative index – an immunohistochemical study was performed. Patients with identified c-MYC gene aberrations received treatment, which included 8 courses of polychemotherapy according to the R + Hyper-CVAD scheme and high-dose chemotherapy according to the BFR scheme with autologous hematopoietic stem cell transplantation. Patients with DLBCL, in whom c-MYC gene aberration was not detected, were assigned to the group of intermediate and low malignancy. They received a polychemotherapy regimen according to the R-CHOP-21 scheme (up to 8 courses).

Results and conclusion. For the first time in Kazakhstan, we studied the incidence of c-MYC proto-oncogene aberrations, BCL2 protein expression and proliferative activity (Ki-67) in DLBCL patients, which made it possible to identify groups of highly aggressive tumor and intermediate, low malignancy, apply personalized polychemotherapy programs and evaluate the immediate treatment efficacy. This approach made it possible to increase treatment effectiveness in the group of patients with highly aggressive DLBCL and to achieve comparable results with therapy in patients with a more favorable prognosis.

Objective: to evaluate the possibilities of strain elastography (SE) in eSie Touch mode and shear wave elastography (SWE) with ARFI (Acoustic Radiation Force Impulse) technology in Virtual TouchTM Tissue Imaging (VTI) for diagnostics lymphomatous superficial lymph nodes (LN).

Materials and methods. The prospective study included 168 patients with enlarged superficial LN. Based on a previous histological examination, patients were divided into three groups: group 1 (n = 108) – patients with lymphomas; group 2 (n = 30) – patients with metastatic superficial LN; group 3 (n = 30) – patients with reactive (inflammatory) changes in superficial LN. All patients underwent SE and SWE elastography of the enlarged LN using eSie Touch and VTI modes respectively.

Results. The SE data: reactive LN was characterized by elastotypes 1 and 2 with a predominance of elastic structure in 90.0 % of cases. In patients with lymphomas, the elastotype 3 was more often determined (58.3 %). The stiffest LN with the elastotype 4 were metastatic LN, detected in 66.7 % of patients from this group. The results of VTI elastography showed that the stiffest structure is typical for metastatic LN (elastotypes 5–6 in 63.3 % of cases). Lymphomas had an intermediate degree of stiffness (elastotypes 3–4 in 81.5 % of cases). The lowest indicators of elasticity were found in patients with reactive LN (elastotypes 1–2 in 73.4 % of cases).

Conclusion. The qualitative assessment of superficial LN stiffness, both using SE and VTI elastography, demonstrated statistically significant differences in the frequency of various types of superficial LN elastograms with lymphomatous, metastatic and reactive changes, which allows for more accurate differential diagnosis between these types of lymphadenopathy.

There are two factors that are researched, namely the concentration of liquid organic fertilizer consisting of five levels, namely control, 75, 150,  225 and 300 ml L-1 water,  and cucumber varieties consisting of two levels, namely Hercules and Mercy. The results showed that the treatment of liquid organic fertilizer concentration did not significantly affect all observed parameters. The treatment of varieties had a very significant effect on fruit length and diameter, and also had a significant effect on weight per fruit. The best fruit length and weight per fruit were found in the Hercules variety while the best fruit diameter was found in the Mercy variety. There is a real interaction between the treatment of liquid organic fertilizer concentration with cucumber varieties on fruit length. The best fruit length is found in a combination of a concentration of liquid organic fertilizer 150 ml L-1 of water with a variety of Hercules

Biskuit ubi jalar ungu merupakan salah satu produk diversifikasi pangan lokal yang memiliki potensi sumber daya alam khususnya pemanfaatan ubi jalar ungu. Penggunaan tepung lokal akan menghasilkan biskuit dengan karakteristik berbeda dari biskuit yang berbahan dasar tepung terigu sehingga penggunaan biskuit dengan suhu dan waktu pemanggangan yang berbeda akan mempengaruhi karakteristik yang dihasilkan. Penelitian ini bertujuan untuk untuk mengetahui pengaruh suhu dan waktu pemanggangan terhadap karakteristik fisikokimia dan organoleptik serta sekaligus sebagai olahan makanan yang memiliki nilai fungsional. Hasil penelitian menunjukkan faktor suhu dan waktu pemanggangan biskuit ubi jalar ungu berpengaruh nyata terhadap warna, rasa, tekstur, kadar air, kadar abu, kadar lemak, kadar serat kasar dan kadar karbohidrat. Perlakuan terbaik dihasilkan pada suhu pemanggangan 150°C dan waktu pemanggangan 10 menit dengan kadar air 2,86%, kadar lemak 5,54%, dan kadar karbohidrat 88,85%. Sedangkan perlakuan terbaik pada uji hedonik didapatkan pada suhu pemanggangan 150°C dan waktu pemanggangan 10 menit dengan aroma 3,29 (netral), warna 3,14 (netral), dan rasa 3,27 (netral). Hal ini diduga karena panelis cenderung lebih menyukai aroma yang tidak coklat, warna yang lebih khas dan rasa yang tidak pahit.Effect of Baking Temperature and Time on The Quality of Physical, Chemical, and Organoleptic in Purple Sweet Potato BiscuitsPurple sweet potato biscuits are one of the diversified local food products with natural resource potential, especially the use of purple sweet potatoes. The use of local flour will produce biscuits with different characteristics from biscuits made from wheat flour so that the use of biscuits with different baking temperatures and times will affect the resulting characteristics. This study aims to determine the effect of temperature and roasting time on physicochemical and organoleptic characteristics and food processing that has functional value. The results showed that the temperature and roasting time of purple sweet potato biscuits significantly affected the color, taste, texture, moisture content, ash content, fat content, crude fiber content, and carbohydrate content. The best treatment was produced at a roasting temperature of 150 °C and 10 minutes roasting time with a water content of 2.86%, a fat content of 5.54%, and a carbohydrate content of 88.85%. At the same time, the best treatment in the hedonic test was obtained at a roasting temperature of 150 ° C and baking time of 10 minutes with an aroma of 3.29 (neutral), color 3.14 (neutral), and taste 3.27 (neutral). This is presumably because the panelists tended to prefer non-brown scents, a more distinctive color, and a less bitter taste.
