ResumoOs sistemas de óxidos cerâmicos são frequentemente investigados para os mais diversos propósitos, sejam como refratários, pigmentos, cerâmicas eletroeletrônica ou semicondutores fotocatalíticos, entre várias outras aplicações. Muitos deles, como a alumina, a sílica, a zircônia e a titânia, acabam por se tornar ótimas matrizes adsorventes e de catalisadores, mas podem ter seus desempenhos significativamente melhorados com a modificação como outros tipos de óxidos não refratários, mas com excelentes propriedades adsortivas, como o cobre, molibdênio, vanádio, cério, entre outros. No entanto, materiais heterofásicos de sistemas ternários ou quaternários de óxidos metálicos são de difícil controle morfológico e estrutural e poucos métodos são mais adequados para a obtenção deste tipo de material do que o Método Sol-Gel. Um destes sistemas é TiO2-CeO2-V2O5, investigado neste trabalho, do ponto de vista das alterações morfológicas e estruturais que ocorrem ao longo do processo de tratamento térmico, sofrendo transições de fases e coalescência de poros.

AbstractCeramic oxide systems are frequently investigated for the most diverse purposes, whether as refractories, pigments, electro-electronic ceramics, or photocatalytic semiconductors, among many other applications. Many of them, such as alumina, silica, zirconia and titania, end up becoming excellent adsorbent matrices and catalysts, but their performance can be significantly improved with the addition of non-refractory oxides, but with excellent adsorptive properties, such as molybdenum, copper, molybdenum, vanadium, cerium, among others. However, heterophasic materials from ternary or quaternary systems of metal oxides are difficult to control from a morphological or structural point of view and few methods are more suitable for obtaining this type of material than the Sol-Gel Method. One of these systems is named TiO2-CeO2-V2O5, as investigated in this work, and a sample of this system was investigated from the point of view of the morphological and structural changes that occur throughout the heat treatment process, undergoing phase transitions and significant pore coalescence.

Authors: Balasaniantc G. S.
Published: February 2022

The aim of the study was to evaluate the effectiveness of MDR/XDR TB treatment with bedaquiline. Methods. The author analyzed the treatment results of 56 patients in Staint Petersburg in 2017 with MDR/XDR TB whose treatment regimen included bedaquiline. All patients were smear/ culture-positive: 43 (67.8%) cases with XDR MBT; 7 (12.5%) with pre-XDR MBT and only 6 (10.7 %) cases with MDR TB. Results. 35 (62.5%) patients received full bedaquiline course, 16 received the treatment for a few days to 4 months and did not complete the course, 5 patients with XDR tuberculosis who underwent surgery were treated for more than 6 months. The average duration of bedaquiline course was 4.7 ± 0.3 months. Among the 27 (48.2%) patients who completed the treatment effectively, 22 had XDR TB, 3 – pre-XDR TB, and 2 – MDR TB. The median sputum conversion period was 4.00 ± 0.42 months (CI: 3.14 – 4.86). 13 (23.2%) patients interrupted the treatment, but 9 of them had negative cultures for MBT at this time. These patients received bedaquiline for 1 to 14 months. Treatment failure was recorded in 12 (21.4%) patients, and 4 (7.14%) patients died during the intensive treatment phase. In general, 27 patients with a successful outcome had negative cultures at the end of the intensive phase and 9 patients who effectively completed the intensive phase but interrupted the treatment continuation phase. In total, 36 patients (64.3%) had a successful treatment outcome. Conclusion. The analysis showed that routine administration of the drug without consideration for treatment compliance increases the effectiveness of the intensive phase (64.3%) and does not significantly affect general effectiveness of the treatment (48.2%). The high frequency of treatment interruption remains a serious obstacle to improving the treatment effectiveness.

Published: February 2022

The aim was to study the volume of blood loss and the duration of a surgical session in patients with destructive pulmonary tuberculosis using threedimensional anatomical models of the lungs. Methods. The study was conducted in 2020 – 2021 in the State Budgetary Healthcare Institution of the Nizhniy Novgorod region “Nizhny Novgorod Regional Clinical Tuberculosis Dispensary” as part of an internal grant from the Federal State Budgetary Educational Institution of Higher Education “Privolzhsky Research Medical University” of the Ministry of Health of the Russian Federation. The prospective clinical study included 80 patients. All patients were divided into two groups. The main group included 40 patients. Preoperative lung reconstruction was performed for these patients. Thoracic surgeons used the three-dimensional anatomical models of the lungs to study the syntopy of healthy and diseased tissue (visual assessment) and prepare for the surgical session (cutting the model with a scalpel). Threedimensional preoperative lung reconstruction was not performed for the other 40 patients in the control group. In this group, the thoracic surgeons did not use 3D anatomical models of the lungs. Comparison of the results in the control and the main group was carried out using the Mann – Whitney U-test and Spearman and Kendall correlation tests. The obtained data are described with absolute and relative values, boxplots reflecting median (Me) and interquartile interval (IQI), scatter plots with trend lines, and probability density plots. The level of statistical significance of differences for testing the hypotheses was chosen at p < 0.05. Results. It was shown that the volume of blood loss (U = 590; p = 0.042) and the duration of surgery (U = 587; p = 0.041) in patients of the main group are smaller than in patients in the control group. A moderate correlation was established between the volume of blood loss and the duration of the surgical session (ρ = 0.54; p < 0.001) in the main group using the Spearman’s test. Kendall’s test also showed a positive correlation (τ = 0.42; p < 0.001). Conclusion. The established differences between the main group and control group in the volume of blood loss and the duration of surgery due to the inclusion of polymer models of the lungs in preoperative preparation of thoracic surgeons confirm our hypothesis about the effect of additive technologies on the above parameters and indicate the significance of the applied reconstruction method.

PH (pulmonary hypertension) targeted therapy may play an essential role in chronic thromboembolic pulmonary hypertension (CTEPH) patients considered inoperable. Given the limited number of PH-targeted drugs approved for CTEPH, reliable long-term data are necessary on the effects of PH-targeted drugs in patients with inoperable CTEPH. We aimed to evaluate the efficacy and safety of intermittent inhaled iloprost in inoperable CTEPH. Methods. The open randomized controlled trial included 22 inoperable CTEPH patients (aged (Me (25%; 75%)) 48,3 (38,4; 59,5) years; 63.6% females; 9.1% with WHO functional class (FC) IV, 72.7% with WHO-FC III, 18.2% with WHO-FC II; 6-minute walking test (6-MWT) distance of 348 (145; 443) m; mean pulmonary artery pressure (mPAP) of 41.8 (29.3; 52.8) mmHg; tricuspid annular plane systolic excursion (TAPSE) of 16.3 (14.5; 18.2) mm; plasma NT-proBNP of 853.8 (562.2; 1124.2) pg/mL). The patients were enrolled 3 – 6 months after acute pulmonary embolism and were randomized 1:1 to receive either standard therapy with vitamin K antagonists and, if indicated, oxygen and diuretics or inhaled iloprost 5.0 µg / inhalation 4 times a day for 2 weeks every 3 months for 2 years in addition to the standard of care. Efficacy endpoints included changes from baseline in 6-MWT, WHO-FC, echo-parameters, inflammatory markers, time to clinical worsening, and all-cause mortality. Results. At baseline (prior to therapy), there were no significant differences between iloprost and control groups. Levels of C-reactive protein and the interleukin (IL)-1b, IL-6, IL-8, γ-IF, and TNF-α cytokines were increased. At month 24, a mean 6-MWT distance increased by 215 m (p < 0.001) in the patients receiving inhaled iloprost and by 137 m in the control patients (p < 0.01). The control-adjusted difference was +78 m (p = 0.03). WHO-FC improved by two classes in 63.6% in iloprost group vs 0% in the control group (p = 0.028), by one class in 36.4% vs 30% (p = 0.091), and remained the same in 0% vs 70 % (p = 0.018), respectively. Inhaled iloprost delayed the time to clinical worsening (p = 0.0064). Improvements were noted in control-adjusted changes in ePASP (–18.6 mmHg; p = 0.0065), TAPSE (+2.4 mm; p = 0.028), and plasma NT-proBNP (–256.9 pg/mL; p < 0.01). The levels of inflammation decreased significantly in the iloprost group, while remained unchanged in the control group. Combination therapy with inhaled iloprost was tolerated well. One patient died in the control group (p = 0.093). Conclusion. Long-term intermittent inhaled iloprost for patients with inoperable CTEPH may improve their clinical status, hemodynamics, and anti-inflammatory status.

Eosinophils play a protective role and are involved in the pathogenesis of exacerbations in chronic obstructive pulmonary disease (COPD). The study of the role of eosinophils in pathogenesis of COPD, especially during exacerbations, is relevant to selecting the optimal therapy. The aim was to analyze literature data and compare them with the results of our study in real clinical practice. Methods. We analyzed the publications on eosinophil count in COPD in electronic libraries eLIBRARY and National Library of Medicine. In our study, we examined 330 patients, collected their history, and conducted physical examination, spirometry, and laboratory tests. Statistical analysis was carried out using SPSS-18 software.Results. Analysis of publications showed that percent of patients with COPD with a stable eosinophil count of more than 300 cells/μL varies from 12.3% to 17%. This percentage is variable and can reach 37.5% in patients with exacerbations. As many studies show, eosinophilia is one of the indications for inhaled corticosteroids (ICS) and is associated with better outcomes than eosinopenia. In our study, 18.58% of patients were eligible for ICSs because of their eosinophil count, 53.3% because of > 2 exacerbations, 82.1% because of exacerbations or hospitalizations, and 62.1% because their FEV1  was < 50% of the reference value. Among patients with FEV1  < 50%, 61% had > 2 exacerbations, 87.8% had hospitalizations, and 12.7% had eosinophilia. Only 7.57% of patients with COPD met all three criteria for prescribing ICS. 16.2% of patients had eosinophilia and 2 and more exacerbations within a year. 10.3% of patients had eosinophilia combined with FEV1  less than 50%. 6.7% of patients had eosinophilia, 2 or more exacerbations within a year, and FEV1  < 50%. Conclusion. Analysis of literature data and our findings have shown that the eosinophil blood count is one of the important prognostic indicators in COPD. It facilitates selection of the optimal therapy, including triple inhalation therapy.

Authors: Rojekar Arati Adhe , Rojekar Mohit Vijay , Ghanghurde Swati B. , Lalla Poonam
Published: February 2022

Objective: Polycystic ovary syndrome (PCOS) is an endocrine disorder associated with hyperandrogenism marked with hirsutism and ovarian dysfunction. These conditions may lead to the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. These conditions are related to PCOS complications hence our aim was to study and investigate the relationship between high-sensitivity C - reactive protein (hs-CPR) level and glycosylated hemoglobin (HbA1c) level in PCOS patients.
Materials and Methods: Female patients visiting the obstetrics and gynecology outpatient department (OPD), aged between 19 and 45 years with a body mass index (BMI) of 25 to 29 kg/m2. The individuals fulfilling the National Institute of Health (NIH) criteria for PCOS; including amenorrhea or oligomenorrhea and had been clinically diagnosed with hyperandrogenism were served as subjects.
Results: Two hundred and ten individuals with HbA1c of 5.4% have a higher risk of cardiovascular disorders. The study showed the association between increased cardiac risk as measured by hs-CRP and patients with normal HbA1c values with a sensitivity of 77.2% and specificity of 75.99%. The HbA1c cutoff value can be used in the PCOS patients to assess the cardiac risk due to association of HbA1c cut off value with false positivity rate of 15.24%.
Conclusion: In PCOS patients with chronic low-grade inflammation, IR, and the degree of inflammation associated with HbA1c value was observed.

Introduction: Recently, a new strain of coronaviruses, which originated from Wuhan City, Hubei Province, China has been identified. According to the high prevalence of new coronavirus, further investigation on the clinical and paraclinical features of this disease seems essential. Hence, we carried out this systematic review and meta-analysis to figure out the unknown features.
Methods:  This study was performed using databases of Web of Science, Scopus and PubMed. We considered English cross-sectional and case-series papers which reported clinical, radiological, and laboratory characteristics of patients with COVID-19. We used STATA v.11 and random effect model for data analysis.
Results: In the present meta-analysis, 32 papers including 49504 COVID-19 patients were studied. The most common clinical symptoms were fever (84%), cough (65%) and fatigue (42%), respectively. The most common radiological and paraclinical features were bilateral pneumonia (61%), ground-glass opacity (50%), thrombocytopenia (36%) and lymphocytopenia (34%). The study also showed that the frequency of comorbidities and early symptoms was higher in critically severe patients. Moreover, we found the overall mortality rate of three percent.
Conclusion: According to that there are many cases without Computed Tomography Scan findings or clear clinical symptoms, it is recommended to use other confirming methods such RNA sequencing in order to identification of suspicious undiagnosed patients. Moreover, while there is no access to clinical and paraclinical facilities in in public places such as airports and border crossings, it is recommended to consider factors such as fever, cough, sputum and fatigue.
O papel de Contratos Swap na cobertura de risco cambial na importação de viaturas usadas de Japão para Moçambique, 2010-2020
Authors: Charles Alcinda Rui Francisco Chichava
Published: February 2022

Contrato Swap negocea-se a troca de rentabilidade entre dois bens (mercadorias ou activos financeiros). Pode-se definir o contrato Swap como um acordo, entre duas partes, que estabelecem a troca de fluxo de caixa tendo como base a comparação da rentabilidade entre dois bens. Por exemplo: Swap de ouro x taxa prefixada. Se no vencimento do contrato, a valorização do ouro for inferior à taxa prefixada negociada entre as partes, receberá a diferença a parte que comprou taxa prefixada e vendeu ouro. Se a rentabilidade do ouro for superior à taxa prefixada, receberá a diferença a parte que comprou ouro e vendeu taxa prefixada. Esta pesquisa teve como objectivo estudar o papel dos contractos SWAP na cobertura de risco de variação cambial na importação de viaturas usadas de Japão. Para a recolha de dados usou-se a técnica do questionário a 65 agentes exportadores de viaturas usadas e exportadoras particulares, nas cidades de Maputo, Matola, Xai-Xai e Beira e foi feita a regressão logística binária onde concluiu se que existe uma relação significativa entre a crise financeira e a variação da taxa de cambio e assim como, a variação da taxa de cambio deveu-se a falta da cobertura por contrato Swap. Assim, todas as hipíteses nulas estão  acima de 0.05 de Sig, o que valida às hipóteses alternativas.

Published: February 2022

Objective: Periodontal disease is an essential phenomenon in human health. Oral pathogens can cause severe break which may show the way to serious issues in human disease like chronic obstructive pulmonary disease and cardiovascular diseases. Therefore, the aim of this study is to evaluate the antibacterial effect of a series nanoparticles on oral pathogens.Methods: In this study, antibacterial activity of a series of nanoparticles such as MWCNT, CuO2, CaCO3, SiO2, Al2O3, MgO and ZrO2 against oral pathogens such as Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa) was demonstrated. We evaluated the bactericidal effect of the nanoparticles to perio pathogens by measuring the inhibitor zone region. Antimicrobial experiments were conducted in five replicates.Results: As a result, we confirmed that engineering nanoparticles exhibited good bactericidal activity. SiO2 nanoparticle was the most effective on Pg. CaCO3 nanoparticle was the most effective on Aa. The order of the nanoparticle types in which the Pg is most sensitive is SiO2> MgO> Al2O3> ZrO2> CuO> MWCNT> CaCO3. For Aa order is CaCO3> SiO2>MgO> ZrO2> CuO> MWCNT> Al2O3.Conclusion: Our results suggest that engineering nanoparticles have a significant inhibitory effect on Aa and Pg. And, these effects are increased with increasing concentrations of nanoparticles. These results can be further clarified with new studies

Published: February 2022

This study portrays the unique experiences of graduate students in education during the pandemic and the commonalities of the interpretations and essences of those lived experiences. In the Philippines, some graduate students managed to survive in their full-time teaching and graduate education that was entirely remote online classes, where everything was home-based during the pandemic. Sixty-eight full-time teachers enrolled in the different graduate degree programs in education in one of the prestigious universities in the Philippines volunteered to share their stories via emails and informal audio-video chat. Commonalities among the unique and multiple realities of the experiences portray the essence of pandemic phenomenon like balance and equanimity for survival when everything was home-based, the importance of holding on to the lived values and personal traits as a stronghold, fortress, and strong weapon during the crisis, and a clear focus on finishing a graduate degree amidst pressing duties and responsibilities in full-time teaching, in the family, and graduate schooling. Findings suggest further inquiry on the graduate students’ lived experiences during a pandemic across cultures in various colleges and universities to uphold full-time teaching and graduate schooling toward efficient school leadership and governance during difficult times

AbstractThe majority of Indonesian migrant workers who work in the domestic sector are women. As a result, they are vulnerable to cases such as torture, violence, sexuality, and physical and emotional exploitation. In Indonesia, the rule of law against Indonesian Migrant Workers is regulated in Law Number 18 of 2017 concerning the Protection of Indonesian Migrant Workers. However, the existence of this regulation does not specifically apply to non-procedural Indonesian Migrant Workers in the Household Sector who are victims of human trafficking. Every Indonesian Migrant Worker, whether procedural or not, has the right to be protected as part of an Indonesian citizen. Non-procedural Indonesian Migrant Workers in the Domestic Sector are entitled to legal protection in a preventive and repressive manner.Keywords: Legal Protection; Indonesian Migrant Workers; Domestic Workers.AbstrakPekerja Migran Indonesia khususnya yang bekerja pada Sektor Rumah Tangga mayoritasnya adalah perempuan.

AbstractPandemic Covid-19 urges the government to launch PeduliLindungi application as followed by various instructions and ministerial circular letter in various sectors. This study aims to determine the effectiveness of the ministerial instructions and circular letter regarding PeduliLindungi application and also to evaluate quality of PeduliLindungi application and as reference for formulate a regulation that has stronger legal force. The research method used is descriptive qualitative with data collection techniques using literature studies and interviews. The results of the study show that currently the instructions and ministerial circular letter which regulate the use of PeduliLindungi application as condition for obtaining public services have not been effective, because it's legal force is still gray and its application is only for the internal scope of the government in each particular sector. The need for more binding and centralized regulation so that its implementation can be enforced, such as Presidential Decree or Government Regulation.Keywords: Ministerial Circular; Ministerial Instructions; PeduliLindungi Application.AbstrakPagebluk Covid-19 mendesak pemerintah meluncurkan aplikasi PeduliLindungi dengan diikuti keluarnya berbagai instruksi dan surat edaran menteri di berbagai sektor. Kajian ini bertujuan mengetahui efektivitas instruksi dan surat edaran menteri terhadap kewajiban penggunaan aplikasi PeduliLindungi, juga untuk mengevaluasi kualitas aplikasi PeduliLindungi dan sebagai referensi untuk menyusun suatu regulasi yang memiliki kekuatan hukum yang lebih kuat. Metode Penelitian yang digunakan adalah deskriptif kualitatif dengan teknik pengumpulan data menggunakan studi pustaka dan wawancara. Hasil Penelitian menunjukkan saat ini instruksi dan surat edaran menteri yang mengatur penggunaan aplikasi PeduliLindungi sebagai syarat untuk mendapatkan pelayanan publik belumlah efektif, sebab kekuatan hukumnya yang masih abu-abu dan pemberlakuannya hanya untuk lingkup internal pemerintah di setiap sektor tertentu. Diperlukannya suatu regulasi yang lebih mengikat dan terpusat agar pemberlakuannya dapat dipaksakan, seperti Keputusan Presiden atau Peraturan Pemerintah.Kata Kunci: Surat Edaran Menteri; Instruksi Menteri; Aplikasi PeduliLindungi.

probiotics. However, these bacteria caused rare infections mostly in diabetic and immunocompromised subjects in presence of risk factors such as prosthetic hearth valves and dental procedures or caries. The scope of this survey was re-assessing the pathogenic potential of lactobacilli based on the infection case reports published in the last three years. In 2019, 2020 and 2021 17, 15 and 16 cases, respective-ly,.including endocarditis, bacteremia and other infections, were reported. These annual numbers are higher than observed previously. Lacticaseibacillus rhamnosus (13 cases), comprising strain GG (ATCC 53103) with established applications in healthcare, L. paracasei (7 cases), Lactobacillus acidophilus (5 cas-es), L. jensenii (5 cases), Lactiplantibacillus plantarum (3 cases), L. paraplantarum, L. delbrueckii subsp. del-brueckii, L. gasseri, L. paragasseri, Limosilactobacillus fermentum and L. reuteri (1 case each) were involved. Virulence characterization of two strains that caused infections, a derivative of L. rhamnosus GG and L.paracasei LP10266, indicated that increased biofilm forming capacity favors pathogenicity and it is determined by variable genetic traits. This survey highlighted that strains of lactobacilli able to cause infections were little characterized genet-ically. Instead, to avoid that these bacteria become a hazard, genetic stability should be periodically re-evaluated by whole genome sequencing (WGS) to ensure that only non-pathogenic variants are ad-ministered to vulnerable individuals.
Resolution Limit in Statistical Independence and Bayesian Network Scoring Functions
Authors: Gogoshin Grigoriy , Rodin Andrei
Published: February 2022

In this paper we consider the congruence problem that arises in the post-analysis of Bayesian network models reconstructed from different datasets. Apart from the structure, a typical network numerically encodes relationship intensities, assigning numerical score to network edges via the scoring criterion used in the reconstruction process. This scoring is rarely a directly interpretable quantity with proper units of measure and an absolute scale, and often comes short in desirable characteristics of a true metric. This leads to poor portability of edge magnitude considerations between similar networks, originating from different sources. In this work, we address this problem by estimating the effect that data-specific resolution limit has on conditional independence, as reflected by information-theoretic entropy, and by the appropriate modification of MDL score, which removes the inconsistency between the score components in both the meaning and units. We also numerically validate our findings and expose additional performance advantages obtained via this modification.

Research is still lacking regarding the question as to how programs to promote healthy aging should be organized in order to increase acceptance and thus effectiveness. For older adults, ecological factors, such as physical distance to program sites, might predict participation and retention. Thus, the key aim of this analysis was to examine these factors in a physical activity intervention trial. Adults (N=8,299) aged 65 to 75 years were invited to participate and n=589 participants were randomly assigned to one of two intervention groups with 10 weeks of physical activity home practice and exercise classes or a wait-list control group. Response, participation, and dropout data were compared regarding ecological, individual, and study-related variables. Kaplan-Meier curves and Cox regression models were used to determine predictors of dropout. In total, 405 participants completed the study. Weekly class attendance rates were examined regarding significant weather conditions and holiday periods. The highest rates of nonresponse were observed in districts with very high neighborhood levels of socioeconomic status. In this study, ecological factors did not appear to be significant predictors of dropout, whereas certain individual and study-related variables were predictive. Future studies should consider these factors during program planning to mobilize and keep subjects in the program.
PEMBERIAN RESTITUSI SEBAGAI PERLINDUNGAN HUKUM KORBAN TINDAK PIDANA

Abstrak

Perlindungan hukum bagi korban salah satunya memberikan hak restitusi, tidak hanya pada tindak pidana tertentu, tetapi sebagai bentuk distribusi keadilan bagi korban. Keberadaan Undang-Undang yang terkait pemberian restitusi kepada korban telah memberikan aturan untuk perlindungan hukum korban,tetapi pelaksanaan restitusi tersebut kepada korban masih belum banyak diterapkan dan dirasakan oleh korban tindak pidana. Artikel ini hendak menganalisis bagaimana sifat pemberian restitusi dan merumuskan restitusi yang ideal agar dapat memenuhi keadilan terhadap korban tindak pidana. Penelitian ini merupakan penelitian hukum normatif atau penelitian hukum kepustakaan. Hal ini berdasarkan pendapat Peter Mahmud Marzuki bahwa penelitian hukum (legal research) selalu bersifat normatif. Banyak kasus korban tindak pidana tidak mendapatkan restitusi untuk memulihkan keadaannya, baik kerugian material maupun imaterial. Peradilan pidana belum memberikan kepastian atas pemenuhan restitusi. Sehingga diperlukan peraturan khusus mengenai pemberian restitusi dengan model pelayanan dimana korban diberikan pelayanan oleh penuntut umum guna mewakili tuntutan restitusi sehingga menghemat biaya dan meringankan beban korban tindak pidana.
