Published: May 2023

Background

The Chinese government recently introduced a program to buy medical supplies in bulk to reduce the patient cost burden. For patients undergoing percutaneous coronary intervention (PCI), little is known about the effect on outcomes of this bulk-buy program.

Aims

This study investigated whether the bulk-buy program to decrease the price of stents used in PCI affected clinical decision-making and outcomes.

Methods

This single-center study enrolled patients undergoing PCI from January 2020–December 2021. Prices decreased for stents on January 1, 2021, and balloons on March 1, 2021. Patients were grouped by surgical year as either before (2020) or after (2021) policy implementation. All clinical data were collected. To examine whether clinical decision-making for PCI was affected by the bulk-buy program, procedure appropriateness was analyzed using the 2017 appropriate use criteria (AUC). To assess outcomes, the rates of major adverse cardiac and cerebrovascular events (MACCE) and complications were compared between groups.

Results

Study participants were 601 patients in 2020 (before bulk buying) and 699 patients in 2021 (after bulk buying). Results of analysis by AUC for procedure appropriateness were 74.5% appropriate, 21.6% may be appropriate, and 3.8% rarely appropriate in 2020, with no differences for patients who underwent PCI in 2021. Between-group comparisons showed MACCE rates of 0.5% in 2020 and 0.6% in 2021, whereas complication rates were 5.5% and 5.7%, respectively. No statistically significant differences were found between groups (p > 0.05).

Conclusion

The bulk-buy program did not impact physician clinical decision-making or surgical outcomes for patients undergoing PCI.

Published: May 2023

Background

Bronchoalveolar lavage and transbronchial biopsy can increase diagnostic confidence in the diagnosis of hypersensitivity pneumonitis (HP). Improving the yield of bronchoscopy may help to improve diagnostic confidence while decreasing the risk of potential adverse outcomes associated with more invasive procedures such as surgical lung biopsy. The purpose of this study is to identify factors that were associated with a diagnostic BAL or TBBx in HP.

Methods

We conducted a retrospective cohort study of HP patients at a single center who underwent bronchoscopy during the diagnostic evaluation. Imaging characteristics, clinical characteristics including use of immunosuppressive medications and presence of active antigen exposure at the time of bronchoscopy, and procedural characteristics were collected. Univariable and multivariable analysis was performed.

Results

88 patients were included in the study. 75 patients underwent BAL and 79 patients underwent TBBx. Patients who had an active fibrogenic exposure at the time of bronchoscopy had a higher BAL yield than those who were out of exposure at the time of bronchoscopy. TBBx yield was higher when more than 1 lobe was biopsied, with a trend toward higher yield of TBBx when nonfibrotic lung was biopsied compared to fibrotic lung.

Discussion

Our study suggests characteristics that may improve yield of BAL and TBBx in patients with HP. We suggest that bronchoscopy be performed when patients are in the antigen exposure and that TBBx samples are taken from more than 1 lobe in order to improve diagnostic yield of the procedure.

To assess the feeding practices and behaviors of women and young children participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), USDA currently funds the longitudinal WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2). In 2013, the study used time-location sampling (TLS) to enroll a cohort of infants who participated in WIC around birth. The children are subsequently followed across their first six years of life, regardless of their participation in WIC, with an additional follow-up at age nine years. A woman may enroll her child in WIC either during pregnancy or postpartum. For this study, a representative sample of infants enrolled in WIC was desired. Because the associations between WIC prenatal support and education and feeding practices and behaviors are substantively important to this study, the sample needed to include both women enrolling their children prenatally and women enrolling their children postnatally. For prenatal WIC enrollees, we attempted to complete a prenatal interview with the mother prior to the child’s birth. This paper describes the TLS approach used and the challenges addressed in implementation of the sample design and selection for the WIC ITFPS-2. Our approach generated a probability sample (subject to site geographic and size exclusions) using a stratified, multistage design, but there were challenges at each stage of selection. First, a WIC site was selected, and then newly enrolled WIC participants were sampled within selected sites during predetermined recruitment windows based on the site’s average flow of new WIC enrollees. We discuss issues faced, including overcoming incomplete lists of individual WIC sites and discrepancies between projected new WIC enrollment counts and actual flow of new WIC enrollments during the recruitment period.
Strings attached: Sustainability and dependence in five models of local and community media
Authors: Krüger Franz
Published: May 2023

Sustainability is a key issue for local and community media in the Global South as well as the Global North, albeit in different ways. After identifying significant gaps in the sustainability literature, the article presents and discusses a taxonomy of ‘models’ – the relationships that arise around different dominant sources of revenue: commercial, patronage, state, donor and community. Although the models operate in all contexts, particular dynamics develop in situations of poverty and marginalization. Drawing mainly on literature from Africa and other parts of the Global South, it is argued that a broadly political economy approach surfaces issues of power and dependency in each model. The models serve as analytical tools that enable better understanding of the vulnerabilities of media for marginalized communities, where a lack of alternatives gives them disproportionately greater importance. Important new areas of research into issues of power in local and community media are suggested, including ways to reduce the vulnerabilities identified.
YouTube vlogging and dissidence in Zimbabwe: Opportunities from authoritarian media policies
Authors: Mututwa Wishes Tendayi , Gwindingwe Gift
Published: May 2023

This article explores the use of YouTube in the increasing practice of vlogging in Zimbabwe. Vlogging counters authoritarian media policies that restrict the entry of new media players and democratic participation in existing traditional media. This dearth of public debate on traditional media has created a window of opportunities for social media as alternative voices through YouTube ‘televisions’. We consider this a metaphorical yearning for alternative television stations in the mainstream media-dominated context of Zimbabwe. Employing the theoretical concept of counterpublics, this article presents a thematic analysis from three selected YouTube channels: Bustop TV, Goldgator TV and TV 7. The findings reveal that although authoritarian media laws are a huge setback to freedom of expression, YouTube empowers non-professional journalists to challenge those who possess political power. The article establishes that authoritarian media laws are no longer as effective in stifling dissent. We argue new thinking towards a liberal trajectory is called upon.

La biodiversidad es esencial en los ecosistemas cultivados. El presente trabajo tuvo como objetivo evaluar la composición y diversidad de la flora existente en fincas suburbanas de Santiago de Cuba. Se realizaron muestreos en las fincas seleccionadas y se contabilizó el total de individuos, familia, géneros y especies. De diversidad alfa se evaluó la riqueza de especies, dominancia de Simpson, dominancia de Berger-Parker y diversidad de Shannon. Como medida de similitud se tuvo en cuenta la formación de grupos homogéneos mediante un análisis multivariado (CLUSTER). Se contabilizaron un total de 261.024 individuos, 74 familias botánicas, 201 géneros y 238 especies. Por período (poco lluvioso y lluvioso) se encontró una tendencia a la disminución en el número de especies en el periodo lluvioso. Las especies arvenses fueron el grupo más representado, y Leguminosae y Asteraceae las familias más representadas. Aunque la dominancia es variable, existe una distribución homogénea de las especies donde predominan las clasificadas como escasas. La similitud entre fincas es de baja a moderada y se evidencia la existencia de especies comunes con pocos individuos y de especies exclusivas adaptadas a las condiciones de cada finca.

Authors: Rezhepov Kuralbay Zhadigerovich , Alimbayeva Shiirin Bekniyaz kizi
Published: May 2023

The article provides information on the synthesis of new derivatives of gossypol, their modification in order to obtain water-soluble complexes, as well as the analysis of their physicochemical and structural properties. In the above work, three iminoazo derivatives of gossypol were synthesized for the first time, on the basis of which water-soluble complexes were obtained. In the synthesis of gossypol derivatives, heterylamines were used as substituents on the aldehyde group and on the C-4 atoms of gossypol. The physicochemical properties of the synthesized water-soluble complexes were studied by UV and IR spectrometric methods and their structure was analyzed.

A comparative analysis of the UV spectra of iminoazo derivatives and complexes of gossypol derivatives with poly-N-vinylpyrrolidone (N-PVP) showed a slight shift in the main absorption maxima. In addition, various electronic transitions associated with functional groups in gossypol derivatives and N-PVP molecules were observed. This suggested that a complex compound was formed. In order to confirm the structure of the complexes of iminoazo derivatives of gossypol with N-PVP, a comparative study of them with intermediate compounds by IR spectroscopic analysis was carried out and the most probable structures of the obtained compounds were shown.
ABILITY OF GARLIC (ALLIUM SATIVUM L.) TO ACCUMULATE GERMANIUM UNDER NATURAL AND EXPERIMENTAL CONDITIONS
Authors: Polyakov Aleksey Vasil'yevich , Alekseeva Tatyana Vyacheslavovna
Published: May 2023

The ability of garlic to accumulate germanium under natural and experimental conditions is discussed at the article. It was shown that the content of germanium in the bulbs of 24 samples belonging to 19 cultivars of winter garlic and 5 varieties of spring garlic, grown in the flat conditions of the Voronezh, Moscow and Tver regions, as well as in the mountainous conditions of the Shandong province (PRC), Karachay-Cherkessia and Mountain Altai is at a low level. The content of germanium in the bulbs does not exceed 4.2 μg/kg in 23 samples, in the sample grown in the conditions of Karachay-Cherkessia, the content of this element is 5.0 μg/kg.

It was found that the efficiency of the accumulation of germanium in the bulbs depends on the method of feeding the plants. Foliar dressing is about 5 times more effective than root dressing and leads to an increase in the concentration of germanium in the tissues of the bulbs up to 20.0 μg/kg.

It has been shown that the efficiency of germanium accumulation in bulbs depends on the method of application of the germanium-containing substance. More effective is foliar feeding with the addition of dimethyl sulfoxide to the Germatranol solution, which promotes better penetration of germanium into tissues. It was found that roots and leaves accumulate germanium most actively. The concentration of germanium in these organs is 115.2 and 141.0 times higher than in the control. In cloves, the concentration of this element exceeds the control by 37.1 times and consisted of 78 μg/kg.

The presence of biologically active substances (BAS) in the composition of fir hydrolate allows the use of this waste from essential oil production in the manufacture of functional food products. However, the specific taste and aroma of the hydrolate limits its use without prior preparation in the production, in particular of beverages. The purpose of the work is to study the possibility of using carbon-containing sorbents to extract compounds that negatively affect the organoleptic properties of fir hydrolate without a significant change in biologically active substances. The object of study is fir hydrolat (florentine water), obtained in the process of fir oil production by steam distillation. Activated carbons of BAU-A and ABG grades acted as adsorbents. The effect of hydrolate treatment with sorbents (static and dynamic methods) was assessed by changing the composition of the hexane extract of the hydrolate by gas-liquid chromato-mass spectrometry (Agilent 6890N chromatograph), as well as organoleptically. The main components of the original hydrolate are borneol and bornyl acetate. When using the infusion method (static method), the taste and aroma of the hydrolate are optimized only after 3 and 8 hours of contact with BAU-A and ABG coals, respectively, at a dose of 10–12 g/100 cm3, however, the concentration of borneol in comparison with the initial value decreases by 4 times (coal BAU-A). Treatment of hydrolate by filtration (dynamic method) through a layer of adsorbent at a rate of 0.3–1.2 dm3/h significantly reduces the severity of organoleptic characteristics. At the same time, the use of coal of the ABG grade contributes to an increase in the amount of borneol by 15%, of the BAU-A grade by 50% in relation to the initial value. The observed changes are due both to the properties of the adsorbents used and to multiple processes (redox, catalytic) occurring on the surface of the coals. The results obtained allow us to speak about the fundamental possibility of using activated carbons for the treatment of fir hydrolates to extract compounds that worsen the taste and aroma characteristics, while maintaining the main biologically valuable components. The work needs to be continued in the direction of searching for new sorbents and optimizing processing conditions.

The article presents Data on the content of biologically active compounds (BAC) and the total phenolic antioxidants activity (TPA) evaluated for aboveground organs of three species from the Caragana Genus – C. bungei, C. pygmaea и C. spinosa, growing in the Mountain Altai. It was determined that leaves and reproductive organs contain flavonols, catechins, tannins, carotenoids, pectin substances. It is shown that biologically active substances of a plant are synthesized differently depending on the species, habitat and organ of the plant. The highest level of flavonols (36.4 мг/г), tannins (117.2 мг/г) and carotenoids (0.56 мг/г) was registered in leaves of C. spinosa. Catechins predominantly accumulated in the leaves of C. pygmaea (up to 211.3 mg/100g) and inflorescences of C. bungei (up to 205 mg/g). The content of pectin substances was quite high, with the biggest share of protopectins. The highest level of protopectins was registered in inflorescences of C. bungei (5.81%) and leaves of C. pygmaea (3.58%). Pectins are synthesized more in the flowers of C. bungei (0.74%) and leaves of C. spinosa (0.49%). The highest values of antioxidant activity were found in the water–ethanol extracts from the leaves of C. spinosa (1.61 mg/g), which is probably due to the increased content of flavonols and tannins. It was shown that the antioxidant activity of Caragana plants is 71% determined by the content of tannins, 62% by the content of flavonols and 41% by the content of carotenoids. C. spinosa is more promising for finding sources of antioxidants.

The chemical composition of plant polyphenols Plantago major L. and Plantago lanceolata L. growing in Uzbekistan was studied. More than 20 compounds, including 7 flavonoids, 9 phenolic acids, and 8 hydrolysable tannins, the ages of which have been determined using physicochemical methods of research have been isolated from plants. From P. major L., along with well-known phenolic compounds, such as gallic acid, rutin, luteolin, isorhamnetin, hyperoside, quercetin, substances belonging to the class of tannins – 1,2,3,4,6-penta-O-galloyl-β-D-glucopyranose, 1,2,3-tri-O-galloyl-β-D-glucopyranose, 1,3,4,6-tetra-O-galloyl-β-D-glucopyranose and 2 new hydrolysable tannins were isolated – hexahydroxydiphenoyl diester-1-(O-2-O-galloyl-β-D-glucopyranoside)-1-(O-β-D-xylopyranoside), hexahydroxydiphenoyl-1-(O-β-D-glucopyranoside) diester)-2-(O-4-O-halloyl-β-D-glucopyranoside).

From the aerial part of the P. lanceolata L. plant, along with known polyphenols such as gallic acid, quercetin-3-rutinoside, quercetin-3-O-β-D-galactopyranoside, kaempferol, quercetin, rhamnetin, 4 hydrolysable tannins were isolated for the first time: 3-O-galloyl-4,6-hexahydroxydi-phenoyl-β-D-glucopyranose, 2,3-di-O-galloyl-β-D-glucopyranose, 1,2,3-tri-O-galloyl-β-D-glucopyranose, 2-O-bis-digalloyl-4,6-valoneyl-β-D-glucose. Based on the results of chemical (acid and stepwise hydrolysis) and physical (UV-, IR-, 1H, 13C NMR spectroscopy) research methods, it was proved that the diester of hexahydroxydiphenoyl-1-(O-2-O-galloyl-β-D-glucopyranoside)-1-(O-β-D-xylopyranoside), diester hexahydroxydiphenoyl-1-(O-β-D-glucopyranoside)-2-(O-4-O-galloyl-β-D-glucopyranoside) (P. major L.) and 2-O-bis-digalloyl-4,6-valoneyl-β-D-glucose (P. lanceolata L.) are new hydrolysable tannins not described in the literature previously.

It was studied the impact of a water-alcohol extract (70%) from the marine green algae Ulva lactuca L., enriched with a polyphenol fraction, and a herbal preparation – extract of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (Araliaceae) on the indicators of antioxidant protection of the liver and blood plasma of rats under acute stress (vertical fixation by the dorsal neck fold). The total polyphenols and flavonoids content in the extract of U. lactuca made 16.2±1.8 µg GAE/g and 9.10±1.87 g QE/g, respectively, which was 2 times higher than its amount in the Eleutherococcus extract – 7.6±0.25 µg GAE/g and 4.8±0.3 µg QE/g respectively. The antiradical activity against ABTS+ and alkyl-peroxyl radicals of the U. lactuca extract was also almost 2 times higher in compere with Eleutherococcus. The pharmacological effect of the phenolic complex of U. lactuca in Wistar rats under stress was manifested in the stabilization of the antioxidant defense system. It was noted a decrease of the malondialdehyde content, an increase of the antiradical activity level, reduced glutathione content and the activity of enzymes of glutathione cycle in the liver and blood plasma of rats. In terms of efficiency, the extract of U. lactuca was not inferior to the reference preparation Eleutherococcus, and in terms of the ability to restore the activity of antioxidant enzymes and indicators of the glutathione system, it was superior to that. The pharmacological effect of the phenolic complex of U. lactuca, to our opinion, is provided by the action of its constituent flavonoids, phenolic terpenoids, phenolic acids (hydroxybenzoic, hydroxycinnamic, coumaric, synapic), etc., which have pronounced antioxidant properties, which prevents the development of lipid peroxidation and oxidative stress. Thus, the marine green algae U. lactuca is a promising raw material for the development of preparations that can increase the potential of the endogenous antioxidant defense system of the body at stress-induced disorders.

Published: May 2023

Olaszország iparpolitikai stratégiájával, illetve annak EU-s szerepével kapcsolatban elsősorban Adolfo Urso, a Vállalkozásügyi és „Made in Italy” Minisztérium minisztere nyilvánult meg az elmúlt időszakban. A Minisztérium honlapján például sorra jelennek meg a sajtóhírek azzal kapcsolatban, hogy különböző országok képviselőivel lebonyolított találkozások során az európai iparpolitika kerül fókuszba [1]. Ezekből a hírekből kirajzolódik az olaszok azon szándéka, hogy egy integrált, közös európai iparpolitika meghatározó szereplőivé kívánnak válni. Egy Ursoval készült interjúban [2] a miniszter kijelentette, hogy szükség van egy iparpolitikai stratégiai vízióra, és hogy Giorgia Meloni kormánya olyan iparpolitikát képzel el, amely ötvözi az olasz ipar erősségeit és sajátosságait azokkal a gazdasági és termelési szükségletekkel, amelyeket az ökológiai és digitális átállás kényszerít a nemzetgazdaságokra. Kiemelte az autonómia fontosságát mind az energiaellátás, mind a digitális infrastruktúra területén. Ennek kapcsán említésre került az EU félvezetők gyártásában betöltött szerepe, valamint a nyersanyagok nemzetgazdasági előállításának fontossága is. A különböző megnyilatkozásokat Olaszország esetében is elsősorban a zöld és digitális átállás tematizálja.

This paper examines the status of Open Access (OA) publishing in India and reviews its academic, economic, and societal impact. The study adopted descriptive and review methods. Data was extracted from directories, online databases, and websites for analyzing OA trends at the global level and in India. Studies related to the topic were also reviewed to examine the academic, economic, and societal impact of OA publishing on different stakeholders. The study's findings suggest that the number of OA journals indexed in Scopus, WoS, and DOAJ is consistently growing in India. A significant amount of research literature published in Scopus and WoS indexed journals is OA, making India one of the leading nations in the OA movement. Major funding bodies like CSIR, UGC, DST, DBT, and ICAR in India have formulated OA policies and mandated authors to make research outcomes of publicly funded research OA. The present study’s results will aid policymakers in realizing the difficulty associated with OA adoption, contributing to policy formulation and implementation nationwide.

Brahmi Script - is one of the earliest scripts known to India and South Asia and it is also an ancestral script for all the indigenous scripts present in India. The researchers, historians, laymen, etc. need these sources of information systematically and handily. In the scholarly world, a huge amount of data and information (Digital Humanities based collections) related to Brahmi script is available but all this information is scattered in the form of texts, images, videos, etc. This creates chaos to understand the overall story of the Brahmi script from its inception to till date. With these issues, we felt motivated to present the data and information related to Brahmi Script among their users in a more informative, easily accessible, and comfortably understandable manner. In this paper, we have tried to connect all the dots related to Brahmi Script under one umbrella with the help of the Digital humanities tool – VisualEyes. Further, we have mapped these multimedia formats with each other on the historical timeline, interactive maps and story events to establish and understand the relationship among the various facets of the Brahmi Script. The impact of this research is more appealing as it has presented a new dimension for any other script to make it more accessible and easily understandable worldwide while using an innovative open-source tool.

A alelopatia é um processo importante nos ecossistemas vegetais e seus estudos são de grande interesse para agricultura. Os aleloquímicos podem substituir herbicidas sintéticos, com a vantagem de não terem efeitos residuais ou tóxicos. Objetivou-se avaliar a atividade alelopática e sua correlação com o teor de compostos de fenólicos e potencial antioxidante de Portulaca oleracea e Raphanus raphanistrum a partir de diferentes preparações extrativas e concentrações na germinação de Lactuca sativa. Utilizou-se três métodos extrativos: refluxo em água; maceração dinâmica em água e maceração dinâmica com solventes de polaridade crescente. Os extratos concentrados em evaporador rotatório foram diluídos em água, obtendo-se as concentrações (0, 2, 4, 6, 8 e 10 g.L-1). Os parâmetros de germinação avaliados foram percentagem e índice de velocidade de germinação e comprimentos do hipocótilo e da radícula de L. sativa. O efeito alelopático foi correlacionado com o teor de compostos fenólicos (fenóis, flavonóides e dihidroflavonóides totais) e com o potencial antioxidante [poder quelante(PQ) e capacidade antioxidante total (CAT)]. Os extratos aquosos de P. oleracea e R. raphanistrum expressaram maior potencial em suprimir a germinação, índice de velocidade de germinação e comprimentos radicular e do hipocótilo de Lactuca sativa nas maiores concentrações. Os extratos aquosos apresentaram menores teores de compostos fenólicos e CAT, mas indicaram maior potencial quelante. Conclui-se que os efeitos alelopáticos dos extratos são dependentes da concentração e do método de extração. Porém, os extratos aquosos de P. oleracea e R. raphanistrum apresentam maior atividade alelopática contra L. sativa, sobretudo na concentração de 10 g.L-1.

Os microrganismos cavernícolas, principalmente os de litologia ferrífera, são pouco conhecidos. Estes constituem a maior parte da biodiversidade da caverna e desempenham papel fundamental na manutenção do ecossistema cavernícola. O isolamento e a caracterização da microbiota cavernícola podem levar a identificação de novas espécies e a obtenção de substâncias de interesse biotecnológico. O objetivo desse trabalho foi isolar e avaliar as atividades enzimática e antimicrobiana de microrganismos isolados do solo de caverna do Parque Nacional dos Campos Ferruginosos, sudeste amazônico. Foram coletadas amostras de solos da camada superficial interna da caverna GEM-1462 nas diferentes zonas (afótica, disfótica e fótica). Para caracterização das linhagens, utilizou-se a técnica de coloração de Gram e prova bioquímica. Foram avaliadas as atividades proteolíticas, celulolítica, amilolítica, fixação de nitrogênio, solubilização de fosfato e actinomicetos dos microrganismos. A atividade antimicrobiana foi avaliada por meio de ensaio de antibiose, teste de difusão em disco e concentração inibitória mínima contra cepas bacterianas padrão. No total, foram isoladas 10 colônias microbianas distintas e todas apresentaram atividade enzimática, destacando-se a atividade proteolítica. Quatro linhagens microbianas apresentaram atividade antimicrobiana para as cepas Bacillus subtilis e Klebsiella pneumoniae. Este estudo demonstrou a primeira descoberta de atividade biológica dos microrganismos de caverna ferrífera, indicando que a caverna GEM-1462 é uma promissora fonte para prospecção de microrganismos com potencial biotecnológico, principalmente de enzimas proteolíticas.

As the world continues to ponder issues of equity and diversity, U.S. public schools face an expanding demographic divide between teachers and students. While diverse groups of public school students show an increase in population, the teaching workforce in the U.S. remains overwhelmingly White. The purpose of this systematic review is to examine how preservice teachers (PST) are being prepared to be culturally responsive. A total of 26 studies published between 2006 and 2020 were reviewed. The results indicate that PSTs’ learning experiences are varied and tend to be stand-alone approaches focused on changing the attitudes and beliefs of PSTs. Findings also bring to light the vagueness of terminology used in the research to define cultural groups of students, the conspicuous absence of studies related to LGBTQ+ populations, and the lack of study replications. Implications for future research are discussed.
