Nystatyna – skuteczny lek przeciwgrzybiczy
Authors: Sybilski Adam J.
Published: February 2023

W niesprzyjających warunkach lub stanach chorobowych może dojść do rozwoju zakażenia grzybami, najczęściej drożdżakami z rodzaju Candida, i stanu zapalnego przewodu pokarmowego. Zakażenia oportunistyczne u ludzi wywołane przez Candida albicans i inne spokrewnione gatunki mogą manifestować się bardzo różnorodnie, poczynając od pleśniawek jamy ustnej (najczęściej), a kończąc na śmiertelnych ogólnoustrojowych zakażeniach u pacjentów z czynnikami ryzyka. Jednym z najpowszechniej stosowanych antybiotyków polienowych jest nystatyna. Nystatyna była pierwszym antybiotykiem przeciwgrzybiczym, który okazał się bezpieczny i skuteczny w leczeniu chorób o etiologii grzybiczej u ludzi. Jest to aktywny błonowo makrolid polienowy, w zależności od stężenia działający fungistatycznie lub grzybobójczo na drożdże i grzyby drożdżopodobne. Nystatyna ma kilka zalet: minimalne skutki uboczne, wysoka skuteczność, niższy koszt niż w przypadku innych leków przeciwgrzybiczych i łatwość w użyciu. Postać zawiesiny doustnej stosuje się w profilaktyce lub leczeniu drożdżycy ustno-gardłowej oraz powierzchownej, drożdżakowej infekcji jamy ustnej i gardła, w infekcji Candida w jelitach, a także profilaktycznie u pacjentów leczonych dużymi dawkami antybiotyków lub glikokortykosteroidów. W artykule przedstawiono trzy przypadki kliniczne zastosowania nystatyny: 11-miesięcznego chłopca, u którego zastosowano nystatynę profilaktycznie w trakcie antybiotykoterapii, 12-dniowego noworodka z prewencyjnym stosowaniem preparatu oraz 63-letniej kobiety z kandydozą jamy ustnej. We wszystkich przypadkach nystatyna okazała się skuteczna i bezpieczna.

Sars-Cov-2 RNA and Spesific Antibodies in Breast Milk, Should Mother Breastfeeding? : A Literature Review
Authors: Sulistyaningsih Kalista Riski , Izzati Dwi
Published: February 2023

Introduction: Covid-19 is becoming a serious problem worldwide. The spread of disease occurs very quickly, viral mutations are fast and massive. Rules and guidelines change rapidly.  WHO and UNICEF recommend exclusive breastfeeding, even though mothers are confirmed because the benefits are considered greater than the risks. The aim of this study are to answer questions, about whether this virus can transmit vertically through breast milk, and how to properly guide the breastfeeding process in the pandemic. Methods: The source of this literature review is accessed through Scopus, PubMed, and various reputable websites published in 2019-2021. Article search by keyword usage, inclusion criteria and exclusion. Results: 508 articles filtered to prove that the source used is viable and relevant, finally determined 12 articles.  The prevalence of Covid-19 incidence in neonates from confirmed mothers was reported in some studies but there is no evidence that transmission is vertical through breast milk. SARS-CoV-2 RNA is found in some reports but there is nothing to confirm whether it is an active virus or just remnants of RNA that cannot infect. Beside RNA, Sars-Cov-2 specific antibodies were also found to protect neonates. Conclusion: Active transmission of Covid-19 vertically from breast milk has not been detected, should not be an indication of formula feeding or separation baby with mother. The findings of IgA, IgG, and IgM-specific antibodies can be passive protection, because until now no vaccination has been recommended for neonate groups.

Authors: Akyildiz Deniz , Aksoy Sena Dilek
Published: February 2023

This study aimed to evaluate the knowledge and practices of delivery room midwives on delayed umbilical cord clamping (DCC). This descriptive study was conducted with a total of 1,274 delivery room midwives from five regions of Turkey. The data were collected using a Google survey form. Most of the midwives defined DCC as clamping the umbilical cord in term newborns after cessation of pulsations (47.2%), and as clamping the umbilical cord in preterm newborns within 15-30 seconds of birth (31.2%). Their highest DCC time ranged between 0-10 seconds for term and preterm newborns (34.7% and 54.8%, respectively). The rates of applying DCC were 17.6% and 5.3% in term and preterm newborns, respectively. Dealing with the mother (75.6% and 33.4%, respectively), having workload (27.5% and 24.6%, respectively), considering that the newborn would have respiratory distress (16.1% and 33.4%), considering that the newborn would get cold (10.7% and 13.9%, respectively), preventing polycythemia and hyperbilirubinemia (6.7% and 9.7%, respectively), and being afraid of dropping the newborn (5.3% and 19%, 8, respectively) are the most common reasons for midwives not to apply DCC to term and preterm newborns. The majority of the midwives reported that they had no DCC protocol in their institution (80.5%) and did not receive in-service training on DCC (76.5%). This study has concluded that most midwives do not know the correct definition of DCC, do not apply DCC correctly, have quite short DCC times, have no DCC protocol in their institutions and do not receive in-service training on DCC

Introduction: Anemia is a condition in which there is a low concentration of hemoglobin (Hb) levels. Although many causes of anemia have been identified, there are few studies in which they are related to epidemiological factors in the first months of life. Objective of the study: To determine the factors associated with hemoglobin levels in children under 6 months of age hospitalized in a specialized pediatric center in Peru. Material and methods: Cross-sectional study in children under 6 months of age hospitalized in the medical services of a pediatric center during the year 2017, 267 medical records were reviewed, emphasizing clinical and epidemiological characteristics. Results: 61.4% of the infants were female, and only 6.7% of the proportion of the population studied were less than 1 month old. 6.7% had low birth weight, and 53.2% had a normal delivery. The level of anemia in hospitalized children under 6 months of age is 66.7%. Conclusions: According to the bivariate analysis, a significant association was found between hemoglobin levels with the variables age, nutritional status of weight for length and hospital causes. Regarding the multivariate analysis, only an association was found between age and the median Hb present in boys and girls aged 0 to 5 months hospitalized in a pediatric center in Peru.

Authors: Palomino Portilla Eugenio Américo , Quiñones Ávila María del Pilar , Torpoco Baquerizo Isaira Giovanna , Medrano Huallanca María Angélica , Palomino Aguilar Katia Sofía
Published: February 2023

Introduction: Digestive bleeding can put patients' lives at risk, even more so when the origin is not located in routine upper and lower endoscopy. The small intestine is the largest portion of the digestive tract and being a source of bleeding means a diagnostic and therapeutic medical challenge. Clinical case: We presented cases of two female patients, 53 and 60 years old, who develop digestive bleeding, locating its origin in the small bowel and undergoing surgical removal of the affected intestinal segment. The anatomopathological study finds malformed arteries and veins that communicate without an intermediate capillary bed. The diagnosis was arteriovenous malformation, a rare entity in the small bowel. Both cases are reviewed with emphasis on the histopathological criteria and their clinical correlation.

Published: February 2023

Introduction: Prevention and control programs have been created due to the high prevalence of anemia in Peruvian children. Objective: To evaluate the effectiveness of nutritional talks in the reduction and prevention of anemia in boys and girls from 6 to 36 months of age. Methods: Longitudinal analytical study of retrospective cohorts. The sample included 78 children attended at a primary health care center. The information was extracted from a database generated by the center. The hemoglobin (Hb) level was recorded close to the date of the intervention and in subsequent controls ≥1 month. Results: 41 children (52.6%) participated in the nutritional talk, not observing significant differences with the group that did not participate. A higher frequency of anemia was observed in the group that did not participate in the nutritional talk (23%) compared to the group that did participate (0%), a significant difference was evidenced in the time between Hb evaluations (p<0.001). and the indication of micronutrients (p<0.001) for both groups. Despite this, there was no significant difference between the initial and final Hb values. Conclusion: Children whose parents participated in the nutrition talks had less anemia. This could suggest that nutritional talks are effective in preventing anemia.

Authors: Patil Gaurang Suresh , Deshmukh Sonali Vijay , Das Arundhati
Published: February 2023

Objective:

The purpose of this study was to evaluate the amount of root repair that took place at varying intervals of 1 day, 2 weeks, 4 weeks and 8 weeks after intentional contact with microscrews. The results were evaluated by an environmental scanning electron microscope study (E-SEM).

Material and Methods:

Ten orthodontic patients with 2 maxillary and 2 mandibular first premolars (40 premolars) to be extracted as part of the orthodontic treatment were included in this study (age 18–25 years). The position of the roots of the 4 premolars to be extracted was clinically determined and under local anesthesia, microscrew implants were placed in such a way that they directly hit the root from the buccal aspect. Implants were removed immediately after the above-mentioned procedure was performed. On the same day, premolar of the 1st quadrant (Group I) was extracted. Premolar of the 2nd quadrant (Group II) was extracted 2 weeks later. Premolar of the 3rd quadrant (Group III) was extracted 4 weeks later and premolar of the 4th quadrant (Group IV) was extracted 8 weeks later, from the day of intentional damage.

Results:

Significant changes were observed in the deposition of cementum over 8 weeks which were analyzed using ESEM under magnifications of × 50, × 200, × 500, and × 5000.

Conclusion:

The damaged root surfaces due to intentional contact with microscrews showed swift repair and healing within 8 weeks. In case, the root is damaged due to improper placement technique or wrong biomechanics which may result in the implant touching the root surface, a minimum healing period of 8–10 weeks is advocated before commencing further tooth movement.
Isolated pulmonary valve endocarditis with pulmonary annular abscess in a patient of Noonan syndrome
Authors: RAO SHIVANI , NEGI PRAKASH CHAND
Published: February 2023

Right-sided endocarditis is a rare entity, with various series reporting an incidence of 5%–10%. Pulmonary valve (PV) is not only the least commonly involved valve in infective endocarditis (IE), with an incidence of 1.5%–2%, but ‘isolated’ pulmonic valve endocarditis (PVE) without tricuspid valve involvement is even rarer with limited published data. We report a middle-aged man with Noonan syndrome and a dysplastic PV with severe pulmonary stenosis. He presented with a large isolated mobile PV vegetation with moderate pulmonary regurgitation (PR). Initially, he was managed conservatively, but due to persistent fever, pulmonary regurgitation and evidence of pulmonary annular abscess extending into the right ventricular outflow tract, he required surgical intervention. Considering the low incidence of isolated PVE, it poses a challenge for physicians in prompt diagnosis and timely management of the infection.

Ghrelin is a multifunctional hormone constituted of 28 amino acids, which is the endogenous ligand of the synthetic growth hormone secretagogue receptor 1a (GHS-R) ligands. Ghrelin is expressed in different tissues including the central nervous system (CNS). In addition, circulating ghrelin can access different structures of CNS such as hippocampus and ventral tegmental area. Ghrelin has various neuroprotective properties, and it appears to be related to memory retention and formation. In Rolandic epilepsy, although many changes in the physiology of hormones in the neuroendocrine system of patients can occur, the causes of these changes have not been fully elucidated. There are also relations between seizure activity and stages of sleep, which has been shown to affect both endocrine function and sleep. The purpose of this study was to evaluate serum levels of ghrelin in a sample of Egyptian epileptic patients and to evaluate its possible correlations with clinical findings. A total of 60 patients (age: 6.5±1.9) currently receiving antiepileptic drug therapy for Rolandicepilepsy were studied. The control group consisted of 60 healthy volunteers (age: 6.6±2.1) matched for age and gender. In all participants, serum levels of ghrelin were measured using ELISA technique. In the Rolandic epilepsy patients, the mean serum ghrelin level was 175.8±49.1pg/ml, and this was significantly lower than the control group’s level of 445.7±151.4pg/ml (p < 0.001). In conclusion, the significant lower ghrelin serum level in patients with Rolandic epilepsy may support the hypothesis of ghrelin’s antiepilepticpotential and neuroprotective actions.

Published: February 2023

Grain boundaries (GBs) in two-dimensional (2D) materials are known to dramatically impact material properties ranging from the physical, chemical, mechanical, electronic, and optical to name a few. Predicting a range of physically realistic GB structures for 2D materials is critical to exercising control over their properties. This, however, is non-trivial given the vast structural and configurational (defect) search space between lateral 2D sheets with varying misfits. Here, in a departure from traditional evolutionary search methods, we introduce a workflow that combines the Graph Neural Network (GNN) and an evolutionary algorithm for the discovery and design of novel 2D lateral interfaces. We use a representative 2D material, blue phosphorene (BP), and identify 2D GB structures to test the efficacy of our GNN model. The GNN was trained with a computationally inexpensive machine learning bond order potential (Tersoff formalism), and density functional theory (DFT). Systematic downsampling of the training datasets indicates that our model can predict structural energy under 0.5% mean absolute error with sparse (< 2000) DFT generated energy labels for training. We further couple the GNN model with a multi-objective genetic algorithm (MOGA) and demonstrate strong accuracy in the ability of the GNN to predict GBs. Our method is generalizable, material agnostic, and is anticipated to accelerate the discovery of 2D GB structures.
Pressure-driven batch distillation optimal control for ethanol-water separation
Authors: Stojkovic Marija
Published: February 2023

Ethanol-water separation by pressure-swing batch distillation in a double-batch rectifier system is a process under investigation. In this work, a complete global solution to the optimal control problem in the form of a sequential synthesis of controlled trajectories is derived. During this study, the optimal reflux strategy through cyclic operation was extended to the separation of a second non-ideal minimum boiling azeotrope of industrial significance. Under the pressure force, the process driven by the increasing pressure from different "directions", ie. from atmospheric to high-pressure, is researched.
Can room temperature data for tunneling molecular junctions be analyzed within a theoretical framework assuming zero temperature?
Authors: Baldea Ioan
Published: February 2023

Routinely, experiments on tunneling molecular junctions report values of conductances ($G_{RT}$) and currents ($I_{RT}$) measured at room temperature. On the other side, theoretical approaches based on simplified models provide analytic formulas for the conductance ($G_{0K}$) and current ($I_{0K}$) valid at zero temperature. Therefore, interrogating the applicability of the theoretical results deduced in the zero temperature limit to real experimental situations at room temperature (i.e., $G_{RT} \approx G_{0K}$ and $I_{RT} \approx I_{0K}$) is a relevant aspect. Quantifying the pertaining % (room) temperature impact on the transport properties computed within the ubiquitous single level model with Lorentzian transmission is the specific aim of the present work. Comprehensive results are presented for broad ranges of the relevant parameters (level's energy offset $\varepsilon_0$ and width $\Gamma_a $, and applied bias $V$) that safely cover values characterizing currently fabricated junctions. They demonstrate that the strongest thermal effects occur at biases below resonance ($2 \left\vert \varepsilon_0 \right\vert - \delta\varepsilon_0 \alt \vert e V\vert \alt 2 \left\vert \varepsilon_0 \right\vert$). At fixed $V$, they affect an $\varepsilon_0$-range whose largest width $\delta\varepsilon_0 $ is about nine times larger than the thermal energy ($\delta\varepsilon_0 \approx 3 \pi k_B T$) at $\Gamma_a \to 0$. The numerous figures included aim at conveying a quick overview on the applicability of the zero temperature limit to a specific real junction. In quantitative terms, the conditions of applicability are expressed as mathematical inequalities involving elementary functions. They constitute the basis of an interactive data fitting procedure proposed, which aims at guiding experimentalists interested in data processing in a specific case.
Electrocatalytic Scission of Unactivated C(sp3)−C(sp3) Bonds Through Real-Time Manipulation of Surface-Bound Intermediates
Authors: Bakshi Harshal , Lucky Christine , Chen Hsiang-Sheng , Schreier Marcel
Published: February 2023

We demonstrate an electrocatalytic approach to cleave the C(sp3)-C(sp3) bond in ethane at room temperature. This reaction is enabled by time-dependent electrode potential sequences, combined with monolayer-sensitive in-situ analysis, which allows us to gain independent control over ethane adsorption, C-C bond fragmentation, and methane desorption. Importantly, our approach allowed us to vary the electrode potential to promote the fragmentation of ethane after it is bound to the catalyst surface, resulting in unprecedented control over the selectivity of this alkane transformation reaction. Steering the transformation of intermediates after adsorption constitutes an underexplored lever of control in catalysis. As such, our findings widen the parameter space for catalytic reaction engineering and open the door to future sustainable synthesis and energy storage technologies.

Published: February 2023

Cycloparaphenylenes (CPPs) are ring-shaped aromatic hydrocarbons in which benzene rings are connected to each other at the para-positions. In recent years, fluorinated CPPs (FCPPs) have attracted much attention as electron-accepting CPPs as well as strained fluoroarenes. Herein, we report the synthesis, properties, and derivatization of novel FCPPs; F16[8]CPP (1) and F12[6]CPP (2), in which ortho-difluorophenylene units are circularly connected to form CPP structure. The short-step synthesis of 1 and 2 has been achieved by the strategy using macrocyclic nickel or gold complexes. Furthermore, the derivatization of 1 was successfully achieved to afford a new heteroring-containing carbon nanoring; hexadecapyrrolyl[8]cycloparaphenylene 5, where 16 pyrrole rings are densely substituted on CPP framework.

Published: February 2023

Four therapeutic approaches have been developed for the treatment of arteriovenous malformations (AVMs): microsurgery, radiosurgery, embolization, and conservative treatment. The lack of consensus regarding the choice of treatment method and the different specializations of the doctor who are onvolved to the patient with AVM often determine the wrong treatment strategy. We performed a prospective analysis of the results of AVM of the IV degree according to Spetzler‒Martin scale, 4–5 points on the Buffalo scale complex treatment, based on clinical and tomographic data after the use of partial endovascular embolization and radical microsurgical removal of the AVM node assisted by cell saving technology. According to cerebral angiography 4 months follow-up there is no visible AVM vessels, the malformation was completely resected.Treatment of large and giant AVMs (IV and V degrees according to the Spetzler‒Martin scale) requires tailored surgical treatment approache using endovascular, microsurgical and radiosurgical techniques, but in many cases without achieving a radical result. The use of cell saver technology is necessary to reduce the risks of intraoperative complications associated with blood loss during microsurgical intervention, and enables radical removal of the AVM and recovery of the patient. The role of cell saver technology is crucial in vascular microsurgical interventions, which are often accompanied by a significant volume of blood loss, ensuring rapid autologous hemotransfusion and restoration of circulating blood volume. Endovascular embolization is a necessary step to reduce the risks of intraoperative complications during microsurgical intervention, which, together with the use of cell saver technology, makes it possible to achieve radical AVM removal and patient recovery.
Analyses of the relationship between self-expression in social media and the concept of ‘Bildung’: with a focus on the term ‘Mediale Artikulation’ and ‘Strukturale Medienbildung’
Authors:   Koreanisch-Deutsche Gesellschaft Fuer Erziehungswissenschaft, Lee Juho
Published: February 2023

This study aims at understanding self-expression in social media in an educational context. For this purpose, the previous studies in German-speaking area are analyzed first, in which self-expression is considered as identity work or effort to establish social relationships in social media. On the basis of the study by Jung(2005) und Jörissen & Marotzki(2009), self-expression in social media is regarded as ‘Mediale Artikulation’. In this context, this study is focused on the reflective potential of each user with self-expression in social media. Following the term ‘Strukturale Medienbildung’ by Jörissen & Marotzki(2009), the potential of ‘Mediale Artikulation’ for orientation of own life, in the sense of the ‘Bildungsprozess’, is also addressed in this study. In the age of the crises of orientation, in which the individual should seek his own orientation of own life, this study could be instructive with the focus on reflective potential and educational potential of self-expression in social media.

Tribalism and Ethnophobia Among Black South Africans
Authors: Mlambo Victor H , Masuku Mfundo Mandla
Published: February 2023

The paper examines the consolidation and implications of tribalism and ethnophobia among black South Africans. South Africa is considered a xenophobic country. With the demise of apartheid and the subsequent increase in undocumented migration, tensions began to develop, not only against black foreign nationals but also among black South Africans themselves. This paper focuses on how tribalism and ethnophobia have divided black South Africans and removed the need for unity and social cohesion in a post-apartheid era. This paper employed a qualitative research approach where a literature review was undertaken. The othering theory was used as a theoretical lens. Findings reflect that although South Africa is recognized as a rainbow nation because of its many different cultures and customs, it is hidden beneath ethnic and tribal emotions that have stifled the idea of unity and social cohesion. South Africa is still far from eradicating tribalistic and ethnophobic sentiments amongst its black population. Apart from ethnicity and tribalism, race continues to divide South Africa. The political transition of 1994 lacked effective frameworks to unite the various ethnic groups that were for decades segregated by apartheid; instead, the focus was on building a new South Africa. However, this approach missed the mark by not focusing on the importance of ethnic unity and tolerance among black South Africans. Unless these tribalistic and ethnophobic sentiments are addressed, unity and social cohesion in the South African black community is unlikely.
The World He Sought: Nazrul in Coolies and Laborers

Published: February 2023

Kazi Nazrul Islam, the national poet of Bangladesh, envisioned a future possibility for humankind, a community of care. The dominant socio-economic and political thinking of this century, however, finds his vision and unrealizable dream, especially in the light of the cleavages that wall human groupings from another—ethnicity, gender, geography, language, nationality, race, religion, and social class, among others. The focus of this article is to show that the dream has been informing some of the thinking of the last and present century, from a variety of cultural traditions, and that its policy implications, through a number of forums, including the United Nations, offer a future within which the entire human species, together, and the Earth, can mutually thrive and grow.

STEM education aspires toward integrated and contextualized instruction, both difficult goals for teachers. Expertise from within and outside the school are resources for helping teachers access content knowledge and practices in their classrooms. In this project, a STEM coach supported teachers to integrate and contextualize STEM instruction. Connectivity between teachers, outside experts, and other resources indicated opportunities for curricular integration and contextualization and was measured through social network analysis and analysis of teacher journals and interviews. The coach dramatically increased connectivity in the district through bridging and brokering relationships, maintaining a global vision for the district’s STEM initiative, and navigating interpersonal relationships. Teachers utilized the connectivity to expertise to enhance STEM curriculum. Having a central actor (coach) allowed for rapid and widespread advancement of the STEM initiative.

The goal of this study is to examine views regarding STEM education studies pertaining to a variety of disciplines inside an electronic database. In addition, the same keyword was used to search for articles published in the electronic database. 23 studies on STEM education context attitudes were assessed using criteria derived from the associated literature. As a result, Turkey provided the majority of the data, but Jordan, Indonesia, and China each contributed two sets. In research groups, instructors and middle school students mostly participated. University, elementary, and secondary school students participated sequentially. The most notable research explores whether participants' STEM attitudes alter in response to diverse conditions. Next are STEM-related studies. One research focuses on the development of scales. There are two types of STEM attitude factors. The first group consists of attitude-affecting elements. The second one is that factors are associated with attitudes (Personal and academic). Teachers' STEM attitudes were favorable, somewhat positive, and moderately positive. Studies of teachers reveal no gender differences. Also, it is indicated that a negative or no correlation between experience and attitudes. Private school science instructors were more supportive of STEM education than their public-school counterparts. The STEM perspectives of university students were favorable, whereas those of high school students were moderate. University and pre-university perspectives on STEM were not affected by gender. However, some pre-university studies demonstrate gender differences in STEM views. A traineeship or STEM education increased the STEM attitudes of university students. In pre-university STEM programs positively affect attitudes toward STEM.
