Published: August 2022

Shigella sonnei merupakan salah satu bakteri patogen penyebab disentri basiler dengan tingkat prevalensi tinggi di negara berkembang. Bakteri ini dilaporkan resisten terhadap beberapa antibiotik yang direkomendasikan WHO, sehingga diperlukan upaya pencarian senyawa antibakteri baru. Penelitian ini bertujuan untuk mendeskripsikan kandungan fitokimia dan potensi ekstrak etanol umbi, batang dan daun ginseng jawa (Talinum paniculatum) dalam menghambat pertumbuhan S. sonnei secara in vitro. Uji fitokimia ekstrak etanol menggunakan metode Kromatografi Lapis Tipis (KLT).  Potensi antibakteri dilakukan dengan menerapkan metode difusi cakram Kirby Baeur teknik swab dengan perlakuan seri  konsentrasi ekstrak  50%, 75% dan  100%, kontrol positif (tetrasiklin 20%), dan kontrol negatif (DMSO 10%) dengan 5 pengulangan. Dari hasil uji fitokimia diketahui bahwa metabolit sekunder dari golongan steroid ditemukan pada umbi, batang maupun daun ginseng jawa.  Flavonoid hanya ditemukan pada umbi dan daun.  Ekstrak etanol batang dan daun menunjukkan hasil positif untuk tanin dan fenolik.  Alkaloid, saponin dan terpenoid tidak ditemukan pada ketiga ekstrak tersebut.  Ekstrak etanol daun memiliki potensi penghambatan terhadap S. sonnei lebih besar dibandingkan umbi dan batang, terutama pada konsentrasi 100%.  Meskipun demikian zona hambat yang terbentuk masih belum cukup efektif jika dibandingkan dengan zona hambat yang dibentuk oleh kontrol positif yaitu tetrasiklin.  Shigella sonnei a pathogenic bacterium that causes bacillary dysentery – a disease with high prevalence in developing countries. This bacterium has been reported resistant to several antibiotics. Development of new antibacterial compounds is regarded necessary. This study was conducted to describe the phytochemical content and potentials of ethanol extract from the tubers, stems and leaves of fameflowers (Talinum paniculatum) in inhibiting the growth of S. sonnei in vitro. Phytochemical test was performed to the ethanol extract using Thin Layer Chromatography (TLC). Antibacterial potential was assessed using Kirby Baeur disc diffusion swab on different treatment concentrations of 50%, 75% and 100%  with positive control (20% tetracycline), and negative control (DMSO 10%) in 5 replications. The phytochemical tests showed that secondary metabolites from the steroid group were found in tubers, stems and leaves of the famefolowers. However, flavonoids were only found in tubers and leaves. The ethanol extracts of stems and leaves also contained tannins and phenolics. Furthermore, neither Alkaloids, saponins or terpenoids were found in the three extracts. In addition, ethanol extract from the leaves showed stronger inhibitory potential against S. sonnei extracts from tubers and stems, particularly at 100% concentration. However, the inhibition zone formed in the extracts was still less effective compared to the inhibition zone formed by tetracycline as positive control.

The impact of digital transformation on changing legal nature of information in digital form
Authors: Paschenko Ilya Yurievich
Published: August 2022

The article examines the legal nature of digital information in the context of the development of the digital economy and the digitalization of public life. The author draws attention to the fact that information in digital form forms the basis for the emergence of new objects involved in turnover. Turnover, taking into account the need to meet the various needs of the individual, exists both in fact вЂ“ in everyday reality and in virtual space вЂ“ through information systems. In modern circulation in everyday life and the electronic environment, information can be presented in various forms. It is noted that in the conditions of rapid development of information technologies, the right to access information becomes important, and the information carrier loses its previously known importance in legal relations. In the conditions of digitalization, the division of new turnover objects into two varieties is proposed. The first group consists of objects that exist in the usual real form, but acquire an electronic form. Transformation accelerates turnover and allows us to work out optimal ways to exercise rights to such objects. The second group is formed by objects that arise and exist in virtual space within the framework of information systems. The possibilities of using such objects are determined by the level of development of information technologies. It is impossible to predict the appearance of new objects of economic value in the digital economy, and the choice of legal economy tools is not always a suitable way of law-making. Special attention is paid to information as a basis for turnover objects in the context of the theory of absolute and relative rights. The attempt to establish the ownership of information and limited property rights is analyzed, and the conclusion is made about the problematic existence of such structures. At the same time, the author shows a change in the understanding and essential meaning of information as a category in the conditions of digital transformation. It is concluded that it is necessary to develop a concept of digital information regulation.

Authors: Egg Rosas Erich A. , Mendoza-Arias Leslie M.
Published: August 2022

In his brilliant article published under the name Anxiety level of first-year medical students from a private university in Peru in times of Covid-19, he shows us that of 57 first-year medical students, 75.4% suffered from high levels of anxiety during the current pandemic, which seemed to me a disturbing result, since it is a condition that has been involving practically all of us in recent years. We can also observe that a significant association was found between the female sex and the presence of anxiety1, which would mean that this impact has a certain degree of preference in terms of sex. It is essential to give the appropriate importance and receive treatment as soon as possible to this mental health problem and thus avoid even more serious consequences, therefore, both family and professional support should be had.

Introduction: Anaplastic Large T-Cell Lymphoma is an infrequent pathology, determined by the expression of CD30, with different characteristics in its presentation and being more aggressive according to the expression of ALK. Objectives: The present study seeks to determine the epidemiological, clinicopathological and prognostic characteristics of patients with Anaplastic Large T-Cell Lymphoma. Methods: Descriptive, retrospective study of patients diagnosed with Anaplastic Large T-Cell Lymphoma of the National Institute of Neoplastic Diseases (INEN) between 2006 and 2016. Results: The pathology of 86 patients was analyzed and reviewed, 57% were men and 33% women, of the total population 21.9% were positive for ALK. 48 of the patients were found in CD I and II and 36 between stages III and IV. 57 patients had low or low-intermediate risk, while 26 had high-intermediate and high risk. The estimated overall survival was 40.8% at 5 years, in the group of patients with ALK + it was 67.4% and in the group with ALK- it was estimated at 30.2%. Conclusions: Anaplastic Large T-Cell Lymphoma is an aggressive disease, with a heterogeneous distribution with respect to age and slightly more frequent in males, with ALK and the international prognostic index as important prognostic factors.
Cutaneous loxoscelism predominantly edematous. Case report

Published: August 2022

The spider bite of the genus Loxosceles is a public health problem in regions of Latin America. In Peru, it occurs more frequently in homes in the coastal region and could have serious consequences, including death in the case of cutaneous and visceral loxoscelism (CVL). The case of a pediatric patient with a suspected spider bite is presented below. The clinical picture developed with marked edema of the face and neck, without developing respiratory distress and without evidence of systemic compromise. The slow resolution of the edema and the lack of response to the treatment of choice for angioedema allowed us to guide the diagnosis to predominantly edematous cutaneous loxoscelism (CLEP), which is an infrequent form of presentation.

Objectives:

Despite the various treatment approaches proposed for major depressive disorder (MDD), the right treatment protocol for different patients is not the same. Supplementation of L-carnitine to antidepressants has been recommended in some studies; however, different results have been reported. This study aimed to evaluate the effectiveness of adding L-carnitine to sertraline in the treatment of patients diagnosed with MDD.

Material and Methods:

This double-blind randomized controlled trial was conducted on 60 patients with MDD. The severity of the depressive disorder, as the primary research outcome, was assessed using the Beck depression inventory. The intervention group received 1000 mg of daily L-carnitine oral capsule along with 100 mg of sertraline; and the control group received a placebo (oral capsule containing 1000 mg of starch), along with 100 mg of sertraline every day. The primary outcome was assessed at baseline, the 3rd, and the 6th week.

Results:

Although depression score decreased in both groups over time, the difference between the two groups was not significant (P = 0.634). Three patients reported adverse side effects; however, the difference between the two groups was not significant (P = 0.554).

Conclusion:

Supplementation of L-carnitine to sertraline in patients with MDD did not show a significant effect on the improvement of depression severity.

Objectives:

Children spend the daytime participating in classes and sports. Hence, as the general caregiver of children during school hours, the teacher has a role in managing those with asthma. The present study aims to identify teachers’ knowledge, attitude, and experiences about childhood asthma in primary and secondary schools in Ilorin, Nigeria.

Materials and Methods:

A cross-sectional study was conducted among 1532 teachers from 64 schools (24 primary and 40 secondaries) selected through multistage sampling. A 40-item Asthma Knowledge Questionnaire was used to assess teachers’ knowledge about childhood asthma. A score of <22 out of 40 was considered suboptimal knowledge of childhood asthma.

Results:

The response rate was 92.8%. Two-thirds of respondents were female. The overall mean age was 33.8 ± 8.1 years. The median (interquartile range [IQR]) teaching duration was 6 (3–11) years. The teachers had the highest median score (60.0%) in the triggers domain and the lowest median score (33.3%) in the symptoms domain. The overall median (IQR) knowledge score of the primary school teachers was 50.0 (30.0–65.0%), and for the secondary school teachers was 52.5 (30.0–65.0%), P = 0.689. Two hundred and ninety-one (55.1%) primary teachers and 479 (53.6%) secondary teachers had suboptimal knowledge. Teachers with an asthmatic relative, an asthmatic child in the class, or who previously witnessed a child with an asthmatic attack had – significantly better asthma knowledge, with each P < 0.05.

Conclusion:

About half of the teachers surveyed had suboptimal knowledge of asthma. Strategies to improve teachers’ knowledge are crucial for improved childhood asthma management in Ilorin schools.
Pilgrim Signs in the Context of European Cultural Practices
Authors: Troitskaya Anna A.
Published: August 2022

The main purpose of the paper is to trace the continuity of the form of pilgrim signs: Renaissance secular hat badges inherited the shape and composition of late medieval pilgrim badges. More than a hundred European portraits of the late 15th — first half of the 16th century represent a model in a headdress decorated with a similar medal or badge, often with an emblematic image inside. This accessory originates from the religious tradition of keeping small medallions from pilgrimage sites, made of cheap metals or wax and known as “pilgrim signs”. The relevance of the research lies in the comparison of cultural traditions usually studied separately from each other due to their belonging to different periods of art history, as well as in an attempt to trace their continuity. The author analyzes the process of transferring the semantic meanings of pilgrim badges from the religious sphere to the field of socio-cultural practices associated with secular aristocratic fashion and the goals of personal self-identification. The article highlights the main aspects of the existence and functioning of pilgrimage signs, analyzes the practices of their purchase, wearing and storage. The author examines the development of their external forms, the variety of materials, as well as the meanings with which these signs were endowed in everyday life. There is found that Renaissance hat badges still retained the meaning of religious patronage. In some examples of portrait images, there is presented the practice of wearing jewelry badges-brooches that were part of aristocratic fashion suits, the elements of which can be interpreted in the context of personal self-identification practices. In this role, the hat badges imply a kind of expression of feelings, moods and intentions of the person portrayed. In the process of comparing the Renaissance brooches and pilgrim signs, there is also manifested their significant semantic difference organizing the visual narrative.
