This case report describes a rare case of progressive muscle weakness in a patient treated for eosinophilic fasciitis (EF) for many years before being diagnosed with a second autoimmune disease: dermatomyositis. Our case is a report of a 65-year-old male diagnosed with eosinophilic fasciitis 7 years before being evaluated in our service at Mayo Clinic in Jacksonville, Florida, due to progressive muscle weakness despite the chronic treatment with methotrexate. Contrast-enhanced magnetic resonance imaging of the lower extremity showed enhancement throughout the thigh musculature, which led us to pursue biopsies of the fascia and muscle in order to confirm the diagnosis of EF associated with myopathy. This case illustrates the need to consider the possibility of myopathy in patients diagnosed with EF whenever muscle weakness is more prominent than expected.

Проведены экспериментальные исследования процесса испарения жидкости в условиях акустико-вакуумного воздействия. На основе полученных значений массы испаряющейся жидкости и давления паров жидкости в замкнутой ёмкости выявлен резонансный эффект. Появление резонансного эффекта характеризуется активным кипением жидкости при совпадении частоты системы «парогазовая смесь + купол + вакуумная камера + слой жидкости» и частоты акустического воздействия в условиях пониженного внешнего давления. Для измерения давления паров жидкости в состав экспериментального стенда введен купол, позволяющий увеличить давление паров жидкости и зарегистрировать его значение используемой аппаратурой. Получена тарировочная характеристика лабораторных весов в виде зависимости изменения массы груза от значений давления в вакуумной камере. С использованием полученной тарировочной характеристики лабораторных весов, работающих в условиях акустико-вакуумного воздействия, получены значения изменения массы жидкости при различных значениях внешнего давления в вакуумной камере. Полученные результаты могут найти применение в области акустико-вакуумной осушки и очистки различных поверхностей.

Non-pharmacological interventions in the management of atopic dermatitis
Authors: Gangadharan Geethu
Published: April 2021

The diagnosis and management of atopic dermatitis are often challenging due to the complexity of its etiopathogenesis and the variety of presentation. Atopic dermatitis is one of the very prevalent dermatoses in which drug therapy alone will not suffice. However, it also requires a logical modification of the patient’s dayto-day activities and his microenvironment. For this, the patient has to understand the disease very well, and knowledge regarding the disease, conditions the patient, for the prolonged treatment course. Various nonpharmacological interventions play an important role in achieving this.

Authors: Dominic Swapna , Asokan N. , Nandakumar G. , George Biju
Published: April 2021

Objectives:

The objectives of the study were (1) to study the fine-needle aspiration cytology (FNAC) features of skin lesions of leprosy, (2) to determine the agreement between FNAC and histopathology to classify leprosy into different groups of the spectrum, and (3) to determine the sensitivity and specificity of FNAC to classify leprosy into different groups of the spectrum against the gold standard of histopathology.

Materials and Methods:

All newly diagnosed cases of leprosy who attended the outpatient department of dermatology and venereology of a tertiary referral center during the 16 months study period were included in this cross-sectional study. Based on FNAC and histopathology, patients were classified into different groups of the spectrum. Agreement between FNAC and histopathology to classify leprosy was determined by Kappa statistics. Sensitivity and specificity of FNAC to classify leprosy were determined against the gold standard of histopathology.

Results:

All the 47 study participants had histopathology features of leprosy. FNAC could obtain adequate aspirate in 30 patients (63.8%), who were considered for further analysis. There was moderate agreement (76.6%) between classification of leprosy by FNAC and histopathology on Kappa statistics (Kappa value 0.766). FNAC showed 80–100% sensitivity and 84–100% specificity to classify leprosy against the gold standard of histopathology.

Limitation:

Small sample size.

Conclusion:

When adequate aspirate is obtained, FNAC could serve as a useful tool in classification of leprosy.

We demonstrate here that a porous free-standing silver foam cathode in an electrolytic flow electrolyzer mediates efficient electrolysis of 3.0 M bicarbonate solutions into CO. These results have direct implications for carbon capture schemes where OH- solutions react with CO2 to form bicarbonate-rich solutions that need to be treated to recycle the sorbent and recover the CO2. Our study shows a viable path for replacing the high-temperature thermal process currently used to recover CO2 from these carboncapture solutions by using electricity to drive the conversion of bicarbonate into CO2 and subsequently into CO. The use of free-standing porous silver electrodes was found to yield electrolysis performance parameters (e.g., a Faradaic efficiency for CO production, FECO, of 95% at 100 mA cm2; <3% performance loss after 80 h operation) that are superior to results obtained in bicarbonate electrolyzers that utilize conventional carbon-based gas diffusion electrodes (GDEs) designed for gaseous CO2 fed electrolyzers. This liquid-fed bicarbonate electrolyzer achieves high CO formation rates with the added benefit of not requiring an energy-intensive CO2 regeneration step that would be necessary for the electrolysis of gaseous CO2. These findings represent a potentially important step in closing the carbon cycle.
Gd Matrix Effects on Eu Isotope Fractionation in Geological Rocks Using MC-ICP-MS: Optimizing Europium Isotope Ratio Measurements in Geological Samples
Authors: Lee Seung-Gu , Tanaka Tsuyoshi
Published: April 2021

Eu has only two isotopes (151Eu and 153 Eu). Eu and Gd are one of the rare earth elements that are very difficult to completely separate from each other. Eu isotope ratio can be determined by MC-ICP-MS using internal Sm or Gd spikes to correct for mass discrimination. NIST3117a ultrapure chemical reagent shows almost no Eu isotope fractionation regardless of the kind of normalization isotope pair. However, Eu isotope ratio in the silicate rocks was effected by Gd matrix during MC-ICP-MS measurement if a trace amount of Gd impurity remains in the purified Eu fraction. In this report, we tried to determine optimizing conditions for precise and accurate Europium isotope ratio measurements in geological samples using MC-ICP-MS. The pure Eu fraction with almost no Gd matrix separated from geological samples and NIST3117a ultrapure chemical reagent show almost same degree of Eu isotope fractionation regardless of the kind of normalization isotope pair. However, Eu isotope ratio in the silicate rocks was effected by Gd matrix during MC-ICP-MS measurement using if 154 Gd interference relative to 154 Sm as internal standard is more than ca. 0.1%. Particularly, highly fractionated granite and high silica volcanic rock with extremely low Eu concentration compared to Gd require high – purity Eu separation with a high recovery rate to obtain the true value of the Eu isotope fractionation in the geological rocks.

The SARS-CoV-2 pandemic has highlighted the weaknesses of relying on single-use mask and respirator personal protective equipment (PPE) and the global supply chain that supports this market. There have been no major innovations in filter technology for PPE in the past two decades. Non-woven textiles used for filtering PPE are single-use products in the healthcare environment; use and protection is focused on preventing infection from airborne or aerosolized pathogens such as Influenza A virus SARS-CoV-2. Recently, C–H bond activation under mild and controllable conditions was reported for crosslinking commodity aliphatic polymers such as polyethylene and polypropylene. Significantly, these are the same types of polymers used in PPE filtration systems. In this report, we take advantage of this C–H insertion method to covalently attach a photosensitizing zinc-porphyrin to the surface of a melt-blow non-woven textile filter material. With the photosensitizer covalently attached to the surface of the textile, illumination with visible light was expected to produce oxidizing 1O2/ROS at the surface of the material that would result in pathogen inactivation. The filter was tested for its ability to inactivate Influenza A virus, an enveloped RNA virus similar to SARS-CoV-2, over a period of four hours with illumination of high intensity visible light. The photosensitizer-functionalized polypropylene filter inactivated our model virus by 99.99% in comparison to a control.
Factors Affecting Lichen Diversity in Manor Parks of Pskov Region (Northwestern Russia)

Published: April 2021

The article describes the results of studies of the factors affecting lichen diversity in 46 manor parks of the region of Pskov. The investigated parks were founded in the end of XVIII – beginning of XX centuries. Twenty of them are fragmented and currently occupy less than 5 ha, the area of nine parks varies from 5 to 10 ha, those preserved within historical boundaries cover from 11 to 100 ha. Manor parks are situated both within the settlements’ boundaries (31 parks) and outside the settlements either bordering forest (12) or agricultural lands (3). Ten of the former border the forests. During the study 166 lichen species were identified. Statistical methods were performed to investigate the factors affecting lichen diversity in manor parks. Linear regression analysis was used to examine the dependence of the lichens species number on the park age/date of park creation (dispersion pattern), area of the parks (box plot), substrata diversity (dispersion pattern), and the dependence of the epiphytic lichens species number on tree and shrub species diversity (dispersion pattern). With the biserial correlation coefficient the impact of the settlement and the presence of the surrounding natural forests was calculated. Correlation analysis was performed to demonstrate the colligation between lichen species composition of the parks located in different subzones of forest zone in the region of Pskov. Our findings show that the number of lichen species depends on the park area (p = 0,0315), the variety of substrate types (p ˂ 0,001), and the variety of trees and bushes planted (p ˂ 0,001). The date of park creation and the presence of the surrounding natural forests do not influence the species diversity of lichens. We reveal that the location of the parks in a specific subzone of forest zone (southern taiga and mixed coniferous-broad-leaved forest) has no significant effect on the lichen species composition. The species richness of lichens tends to decrease in parks located within the settlements. The data obtained indicate not only the similarity of the species composition of lichens in the studied communities, but also the long-term development of lichen park communities in comparable climatic and landscape conditions.
Corticolous Lichens of Belarus. II. Obligate and Facultative Epiphytes
Authors:   Francisk Skorina Gomel State University, Tsurykau A. G. ,   Samara National Research University
Published: April 2021

The lichen biota of Belarus lists 406 corticolous species. Of these, 213 (35.7%) species are obligate epiphytes. Crustose lichens make up the majority of obligate epiphytes (157 species, or 73.7%). Apparently, this can indicate the decisive role of the morphology and chemistry of the substrate for the closely contacted lichen thallus. Facultative epiphytes are represented by 193 species, which are quite widely represented by foliose and fruticose life forms (51.3%). Facultative epiphytes inhabit rotting and processed wood, stony substrates, soil (including forest litter), mosses, leaves (needles), root turnouts and metal objects. Wood is inhabited by 154 facultative epiphyte species, of which 80 lichens are strongly epiphyticlignicolous. The lichen diversity of tree bark and wood is relatively similar; the value of the Sørensen-Dice index is equal to 0.51. Soil is the second most important substrate after wood for facultative epiphytes. It is inhabited by 55 lichens, most of which are represented by Cladonia and Peltigera species. 46 species of facultative epiphytes were found on mosses. These are represented mainly by cyanobiont-containing lichens, broad-lobed species, as well as many by the representatives of the genus Cladonia. The stony substrate is suitable for 43 facultative epiphytes species and is characterized by a high specificity of lichen biota. Its Sørensen- Dice index is equal to 0.13. Most of these representatives are common in urban environments. Fungi, lichens, root inversions, leaves, and metal are predominantly inhabited by multisubstrate lichen species.

Virtual reality (VR) has been integrated and used with smartphones as one of the digital entertainments such as in gaming and movie streaming. With emergent of various VR brands in the market, it concerns the public on the possible side effects of VR on the ocular performance specifically on tear film stability and ocular discomfort. The purpose of this study was to compare the change on non-invasive keratograph tear break-up time (NIKBUT), tear meniscus height (TMH) before and after the use of VR for 30 minutes, and to measure the ocular discomfort after the use of VR quantitatively. Thirty-two subjects were recruited in this study and all the subjects were divided randomly into two groups; VR and laptop (used as a control) groups. Each subject needed to watch a movie for 30 minutes using the respective devices. The changes of tear film stability and ocular discomfort before and after the use of the devices were then compared and the results showed that there was no significant difference (p>0.05) after 30 minutes of the use. Comparison of the ocular parameters between the devices on post-watching activities was also not significant (p>0.05). Use of VR did not give any signs of dryness to the eyes and it can be used without any discomfort even after 30 minutes usage of the devices.

The Impact of Ketogenic Diet on Colorectal Cancer Progression and the Co-evolution of Gut Microbiota: A Research Protocol
Authors: Shirdarreh Melika , Sadeghi Yasamin , Rahimi Tina
Published: April 2021

Introduction: To date, the ketogenic diet (KD) has been shown to improve certain health conditions such as seizure. These positive effects have been partly mediated through the gut microbiome. However, research on KD’s impact on colorectal cancer (CRC) and the gut microbiome of cancer patients that use KD has been scant. This study aims to investigate the role of KD in the co-evolution of gut microbial composition and CRC progression. We hypothesize that KD alters overall species diversity through either elimination of harmful bacterial genera or perpetuation of beneficial gut microbiota which could ultimately be the mechanism underlying positive CRC outcomes.
Methods: In order to test this hypothesis, we propose a murine study using ApcMin/+ (multiple intestinal neoplasia) CRC mouse models in C57BL/6J background. The mice will either be given normal chow (control group) or KD (87% fat) for
8 weeks. Mice will be euthanized at the end of the experiment and analyzed in terms of polyp size and polyp number in the small intestine and colon. Frozen colon tissue will also be used to extract mRNA for quantitative polymerase chain reaction (qPCR) analysis of TH17 cytokine production. Gut microbiome composition will be analyzed by sequencing of 16S rRNA genes. To compare microbiome structure between diet groups, alpha diversity will be used to measure the differences in gut microbial structure in the control and experimental groups.
Results: We would expect that mice fed a KD would have altered microbiota diversity, a decreased level of cytokine production, as well as fewer and smaller polyps (as measured in the small intestine and colon).
Discussion: Analysis of the gut microbiota post-treatment, in conjunction with assessment of cytokine levels will help to set correlations between microbial gut activity and CRC progression.
Conclusion: The results of this experiment could give insight into the impact of KD on development and progression of CRC; which could be used to develop therapeutic or dietary interventions.

Objetivos: descrever as características dos casos de abortamento e analisar a ocorrência de complicações decorrentes de aborto em uma maternidade de referência. Métodos: trata-se de uma pesquisa documental, censitária e de abordagem quantitativa. O estudo foi realizado com 393 mulheres. Os dados foram analisados à luz da estatística descritiva e análise inferencial. A projeto de pesquisa foi submetido e aprovado pelo Comitê de Ética em Pesquisa da Fundação Santa Casa de Misericórdia do Pará, com o número do CAAE 60112316.9.0000.5171. Resultados: ocorreram abortamentos, em sua maioria, em mulheres de idade entre 16 e 23 anos, solteiras, que relataram não serem diabéticas nem fazer uso de álcool, tabaco, outras drogas. A maioria dos abortamentos era do tipo incompleto e retido. Notou-se, entretanto, que nos abortamentos do tipo infectado houve maiores frequências absolutas de abortos complicados. Não foi observada associação entre complicações por aborto com as variáveis do estudo. Conclusão: os resultados deste estudo avultam para a realização de novas pesquisas sobre outras variáveis na análise da ocorrência de abortamentos e suas complicações, além de estudos que utilizem outros desenhos de pesquisa e investiguem fatores protetores para a gestação.

The growth and development of toddlers is influenced by hereditary and environmental factors. Genetic factors, biologically have strong influences on toddlersâ€™ growth in their early years of life. While psychologically, a good interpersonal relation of pregnant women with their families will make them more ready to undergo the pregnancy and childbirth. On the other hand, socially, the level of parental education might affect the nutrition intake and parenting patterns. For the economic factor, the level of family income and their ability to provide sufficient nutrition input might affect the nutritional status during gestation. The nutrition input during pregnancy highly contributes to the fetus growth and development. A poor nutrition input during gestation might cause an Intrauterine Growth Retardation (IUGR) and growth and development disorder. This study aimed to analyze the bio-psychosocial and economic factors of gestation period on toddler growth and development. This is a correlational analytic study with 80 mothers and toddlers as the sample. The data was analysed using univariat, bivariate with Chi square and multivariate with logistic regression. The results show that the statistically significant independent variables which influence the growth and development of toddlers are the mother height (p = 0.001), LILA (p = 0.008), family income (p = 0.007), infant birth weight (p = 0.009) and family support (p = 0.013). While the statistically insignificant independent variable is the mother level of education (p = 0.086).

The COVID-19 pandemic that resulted in a shift towards on-line teaching and learning resulted in countless difficulties concerning the access to efficient education, especially in the case of children from families with a lesser-endowed socio-economic and cultural background, or children with learning problems, with ADHD or various disabilities (visual or healing impairment, intellectual disabilities, autism spectrum disorders, etc.). Moreover, even pupils who actually have technical access to the new teaching-learning system run the risk of losing their motivation for learning.
The efficient activity of and the results obtained by many teachers whose approach has been successful have shown the efficiency of integrated curricula whose teaching tasks are structured in learning sequences and whose testing patterns are personalized. By putting into practice, the principle of cognitive motivation development through an interactive process of teaching and learning that relies on structured learning sequences and employs personalized assessment techniques, reaching formative pedagogical objectives becomes possible even in the on-line teaching-learning system.
Autism, schizofrenie, ADHD. Perspective convergente
Authors: MICLEA Bogdana
Published: April 2021

Over time, continuous efforts have been made to clarify and circumscribe diagnoses of autism, schizophrenia, and attention deficit hyperactivity disorder (ADHD). The diagnostic split between the 3 disorders dominated psychiatry after the 80s, being still used and recognized as such by the diagnostic manuals. Recently a shift and flexibility of the psychiatric paradigm has been noticed. The categorical perspective on mental illness is gradually complemented by the dimensional one. In the last decade, research in the field of neuroscience and psychology has brought evidence in favor of a partial overlap between ADHD, autism and schizophrenia. The hypothesis of a partial overlap can also be supported by non-medical or psychological theorizations, related to common deficits of symbolic structuring of the psyche in achieving a coherent representation of the world and of one’s own person.

The first step in combating speech and language disorders, is checking if specific language development steps from infancy and toddlerhood have been done. Students from families with financial difficulties, that lack early childhood cognitive development, tend to be less skilled in reading or writing.
To avoid school dropout, we focused on identifying these issues when a child starts school and apply a ten week program.
This program has two components, one for teachers and the other for students. The main goal is to identify if certain early development milestones have been met, memory and atention development and phonology conscience. The program has proved it’s eficacity even during the corona virus pandemic

This article describes a research study developed during the webinar organized in order to celebrate 6 th of March as European Day of Speech & Language Therapy. In this research participated Romanian SLTs (N=150). The research was based on the following objectives: to identify the typology of the present used resources in the Romanian SLT field; to implement the Padlet as a tool for collecting and sharing data and to identify the area of resources that has to be developed. Results demonstrated that SLTs mainly use virtual resources (VR=106) in their present work and that material resources that can be used online is the less detailed and mentioned category (MRV=17). The third category of resources is the category of material resources (MR), those that are to be used mainly during face-to-face SLT therapy. This category is represented by a relatively low number of units, compared with VR (MR=61). Regarding the use of Padlet, we consider that this focused-group based research was enhanced with success, participants in the research, even if they were a numerous group, and the research was developed online, had the chance to express their points of view, without difficulties.

Background: The pH of the skin surface is elevated in the elderly therefore it may cause impaired barrier function manifest as various cutaneous abnormalities, including xerosis, pruritus, dermatitis, and skin infections. Consequently, skin care products for the elderly should contain moisturizing ingredients which are formulated to normalize the skin surface pH. Application of pH 4 emulsion is potentially beneficial to improve barrier function in the elderly and promoting skin health. We aimed to determine the difference of effectiveness of pH 4 emulsion compared to identical non pH 4 emulsion on decreasing TEWL in the elderly. A systematic review and meta-analysis was performed of randomized clinical trials assessing the effects of pH 4 emulsion on skin barrier function in the elderly. Methods: Medline Pubmed, Scopus, ProQuest, Cochrane library, ClinicalTrials.gov, the reference list, conference proceedings, researchers in the field of eligible studies were searched. Four studies (n=98 subjects) were included in qualitative analysis of which two studies (n=45 subjects) were included in the meta-analysis. The mean age of the participants was 71.1 years old. Interventions use the application of pH 4 water in oil emulsion (n=2) and pH 4 oil in water emulsion (n=2). Duration of intervention (24 hours-7 weeks) and outcomes of interest varied among included studies. Results: Pooling of data using random-effects model found lower TEWL score in the pH 4 emulsion than in non pH 4 emulsion, with no significant difference (overall effect mean difference -0.068, 95% confidence interval -0.485 – 0.348, p = 0.11, I2=60.1, two RCTs). In addition to that, the qualitative analysis found that the application of pH 4 emulsion increased stratum corneum hydration, decreased skin surface roughness and scaliness, decreased DASI, and improved ICLL length and lamellar organization. Conclusion: The meta-analysis result of the mean differences of TEWL scores lowering effect between pH 4 emulsion and non pH 4 emulsion is statistically inconclusive. This is despite the observation that the pH 4 emulsion appears to be more effective comparatively. The qualitative analysis found that the application of pH 4 emulsion had improved skin barrier function in the elderly. Larger scale, well-designed RCTs assessing the effects of pH 4 emulsion on skin barrier function in the elderly, are still needed.
