Authors: Mahmadiariska Theresia Daniela Ody , Debora Oda , Putri Maria Prieska , Ariesti Ellia
Published: May 2024

Type 2 Diabetes Mellitus is a chronic disease that can significantly impair the quality of life. Individuals with this condition often experience physical and mental disturbances, affecting their activities, medical therapy, rest, and pain perception, all of which are dimensions of quality of life. Factors that can influence the quality of life of individuals with Diabetes Mellitus include their level of knowledge about the disease, economic status, and duration of illness. This study aims to investigate the internal factors related to the quality of life of individuals with Diabetes Mellitus at the Janti Public Health Center in Malang. The research design employed is descriptive correlational with a cross-sectional approach. The study sample consists of 93 respondents selected using purposive sampling. Data analysis was conducted using ANOVA, with the instruments used are the World Health Organization Quality of Life (WHOQOL)-BREF and the Diabetes Knowledge Questionnaire (DKQ24). The analysis results indicate a significant correlation between knowledge (p=0.003 0.05), economic status (p=0.007 0.05), duration of illness (p=0.008 0.05) to the quality of life. The most influential factor is the duration of illness, as respondents who have been suffering for more than 10 years tend to feel that their activities are disrupted by Diabetes Mellitus and may develop complications in other organs, significantly affecting their quality of life. This study can serve as a reference for further scholarly development, thereby facilitating ongoing exploration of factors associated with quality of life.

Intrapersonal conflict is a condition where an individual has two desires that cannot be fulfilled simultaneously. This research aims to identify the description of intrapersonal conflict among nurses. The study design uses a scoping review method. Articles were identified using the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) method. Inclusion criteria for this review article include articles in English or Indonesian, original articles, and articles that use quantitative, qualitative, and mixed research methods published within the last 5 years. A search of articles in this review yielded 819 articles, and the review identified 4 articles that met the inclusion criteria and were subsequently analyzed. The results of the analysis indicate the description of intrapersonal conflict among nurses, namely: (1) Career-related conflicts, hindered by further study; (2) Family-related conflicts. Nurses want to contribute to the family's economy but their partner asks them to take care of the children and the house; (3) Work-family life conflicts or sleep duration; (4) Religion-related conflicts, with an example of a Muslim nurse newly employed at a hospital but facing a mandatory rule to remove the hijab. The conclusion of this review article shows various descriptions of intrapersonal conflict among nurses and suggests that research be conducted to reduce or manage these conflicts.

Purpose: This research sought to assess and contrast the physical attributes of adolescent wrestlers and judo practitioners aged 13 to 16, aiming to identify key physical and motor skills that contribute to performance excellence in these sports. Method: A total of 30 athletes were randomly assigned to the wrestling (n=15) and judo (n=15) groups. These athletes train 4 to 6 days a week. In this study, body composition, horizontal jump test, hand grip strength, flamingo balance test, sit and reach test and shuttle run of combat athletes were evaluated. Statistical analysis was conducted utilizing the SPSS 20.0 program. Findings: Based on the results, the average age of the participants was calculated to be (13.7±1.2) for judo and (14.8±1.7) for wrestling, with their respective sports ages being (5.3±1.3) for judo and (5.6±1.2) for wrestling, and their heights being (161.1±10.7) for judo and (169.4±9.4) for wrestling. Although a significant difference was noted in the lean body mass percentage, the results of the horizontal jump, hand grip strength tests, sit and reach test, flamingo balance test and shuttle run showed no significant variance. Conclusion: The lack of a significant difference in the outcomes observed between judo participants and wrestlers in this age category can be attributed to the similarity of these sports disciplines. The follow-up of the process will provide detailed information about the physical characteristics and performances of combative athletes and will provide scientific contribution to the training and development processes of athletes in this age group.

Invasion risk to the United States from Arapaima spp. hinges on climate suitability
Authors: Wyman-Grothem K , Castello L , Catâneo DTBS , Doria CRC , Magalhães ALB , Patoka J , Stewart D , Watson C
Published: May 2024

Fish in the South American genus Arapaima Müller, 1843 (hereafter referred to as arapaimas) have attracted interest for commercial aquaculture development thanks to their rapid growth rate and high market value. However, management agencies in the United States have expressed concerns about importing and culturing arapaimas due to records of non-native establishment in certain other countries where arapaimas were released or escaped from captivity. We used the Freshwater Fish Injurious Species Risk Assessment Model (FISRAM) to estimate the probability that arapaimas would be injurious (able to cause harm) to native ecosystems, humans, or the economy of the contiguous United States. Risk assessment model inputs were elicited from arapaima experts around the world. Model results were sensitive to the estimation of climate suitability for arapaimas within the contiguous United States, with predicted probability of injuriousness ranging from 0.784 down to 0.321 with different climate suitability inputs. Expert assessors predicted that competition and predation on native species would be the most likely mechanism of impact and expressed a high degree of uncertainty about potential for impacts from pathogens and parasites. We concluded that due to the cold sensitivity of these tropically adapted fish, establishment within the contiguous United States would be highly restricted geographically, limiting potential impacts if introduced outside climatically suitable areas. Existing regulations already mitigate risk of escape from aquaculture in areas where establishment is plausible, but further research into arapaima parasites and pathogens would help reduce uncertainties and suggest opportunities to enhance biosecurity measures if needed.
Niche partitioning among demersal marine fishes at the southern tip of South America
Authors: Alvarez CD , Giussi AR , Botto F
Published: May 2024

Niche differentiation is a means by which species can coexist and avoid competition. In marine food webs, large demersal fish often couple different trophic pathways and can be targets of valuable fisheries. This is the case for long tail hake Macruronus magellanicus, Patagonian toothfish Dissostichus eleginoides, southern blue whiting Micromesistius australis, and southern hake Merluccius australis, which coexist in the southernmost region of the southwestern Atlantic Ocean. In this study, C and N stable isotope and stomach content analyses were used to evaluate possible niche partitioning among these 4 species. Long tail hake and southern blue whiting mainly eat crustaceans, with great overlap in their diet spectra, but they differentiate in their spatial distribution. Southern hake and Patagonian toothfish mainly feed on fish, including the other 2 species, and exploit prey from a broad spatial area. These results suggest a spatial compartmentation of the food web at lower trophic levels, with demersal fish at the higher levels linking distant compartments. Therefore, results of this study show similarities and differences among these 4 demersal fish species, in the trophic and spatial dimensions of their niches, suggesting niche differentiation and probably different roles in the food web.

Az inzulin helytelen használatáról: narratív összefoglaló
Authors: Buzás György Miklós
Published: May 2024

Az inzulin a 20. század első csodagyógyszere volt: cukorbetegek millióinak életét mentette vagy hosszabbította meg, javítva életük minőségét. Az ezredforduló és a felfedezés centenáriuma (1922) kiváló alkalom volt arra, hogy az inzulinról a nemzetközi és a hazai irodalomban könyvek, közlemények jelenjenek meg (1, 3). Az orvostudomány és gyógyszerészet történetében közismert, hogy a mégoly hatékony gyógyszereknek is jelentős mellékhatásai lehetnek. Megfelelő adagolással és a haszon/kockázat mérlegelésével ezek veszélye megelőzhető vagy jelentősen csökkenthető. Az altatók, pszichoterápiás gyógyszerek, cardiacumok, a nem szteroid gyulladásgátlók, antikoagulánsok, a kemoés biológiai terápia mellett ide tartozik az inzulin is, amelynek hypoglykaemizáló hatása képezi alkalmazásának elsődleges területét, de egyben legnagyobb kockázatát is: ez az előnyös és erős hatás a felfedezők és gyártók szándékától eltérően visszaélésekre, téves és helytelen alkalmazására ad lehetőséget. Hangsúlyozom, hogy az inzulin az 1-es típusú cukorbetegség (T1DM) alapvető és megkerülhetetlen kezelése volt és marad. A 2es típusú diabetesben (T2DM) az orális antidiabetikumok egyre bővülő palettája mellett az inzulin alkalmazása jelentősen halasztható, de továbbra is a kezelés szerves része. Mivel a T1DM és T2DM aránya világszerte 1:10-hez, az utóbbiban adják az inzulinkezelések túlnyomó többségét.

Introduction. Removal of wisdom teeth is always accompanied by the appearance of collateral edema of varying severity, pain, neurological dysfunction and inflammatory contracture of the masticatory muscles.

Purpose. To evaluate the use of local apparatus hypothermia and the method of three-dimensional facial scanning for the treatment of patients after extraction of mandibular third molars.

Materials and methods. 60 patients had their wisdom teeth removed. Depending on the group, local apparatus hypothermia (LAH) (study group of 30 patients) and local ice hypothermia (LIH) (control group of 30 patients) were performed after surgery. Evaluation criterion: three-dimensional scanning of the face on days 3, 5, 7.

Results. In the control group, on the 3rd day the size of the edema was 6.31 mm (SD 0.81), on the 5th day – 4.88 mm (SD 0.73), on the 7th day – 3.44 mm (SD 0.88). In the study group, on the 3rd day the size of the edema was 5.09 mm (SD 0.80), on the 5th day – 2.73 mm (SD 0.71), on the 7th day – 1.28 mm (SD 0,62). In the control group, the size of edema on the 5th day changed by 22.67% compared to the 3rd day, on the 7th day by 30.12% compared to the 5th day and by 45.94% compared to 3rd day. In the study group, the size of edema on the 5th day changed by 46.42% compared to the 3rd day, on the 7th day by 53.16% compared to the 5th day and by 75.32% compared 3rd day. Comparison of groups 3, 5 and 7 in terms of absolute values of edema size and percentage change showed a statistically significant difference (p<0.001).

Conclusion. The use of local apparatus hypothermia in the postoperative period can reduce the severity of collateral edema in a shorter period compared to standard methods of local hypothermia.

Authors: Frolova K. E. , Zyulkina L. A. , Yurkevich A. V. , Efremova A. V.
Published: May 2024

Background. An increase in the number of patients with chronic apical periodontitis is becoming a global trend, which is mediated by several factors: the formation of foci of chronic infection, an increase in the number of various odontogenic complications leading to the loss of a causal tooth, a decrease in general resistance and the development of persistent sensitization of the body.

The aim of the study was to evaluate the effectiveness of diagnostic measures based on a complex of microbiological and joulemetric methods in patients with chronic apical periodontitis.

Materials and methods. 25 patients with the established diagnosis of «chronic apical periodontitis» were examined. Microbiological and joulemetric analyses of the root canal system were performed before and at the stages of treatment using the delayed obturation method, which provides for intra-channel administration of a preparation of highly dispersed calcium hydroxide.

Results. The comprehensive analysis of the results of bacteriological and joulemetric studies of the contents of the root canal system in the examined patients at the diagnostic and treatment stages fully corresponded to the clinical picture of the course of this nosological form and reflected the dynamics (negative and positive) of the inflammatory process in the studied periapical region.

Conclusions. The combined use of microbiological and joulemetric techniques increases the effectiveness of therapeutic and diagnostic measures in patients with chronic apical periodontitis, which in turn reduces the risk of possible complications and improves the effectiveness of immediate and long-term therapy results.

Background. Recently, the interest of dentists and physiologists has been focused on the development of a set of informative computerized techniques for an objective analysis of the functional state of the dentofacial apparatus. Achieving certain successes in conducting functional diagnostic examinations contributes to the development of algorithms for complex treatment of patients with generalized periodontitis and premature occlusal contacts.

Goal. Study of the functional state of the dentofacial apparatus according to the parameters of bioelectrical activity of muscles in patients with chronic generalized periodontitis and occlusal disorders in static and dynamic conditions of the lower jaw.

Materials and methods. The study involved 37 people with clinically healthy periodontium, physiological occlusion, and absence of occlusal disorders (Group 1) and 45 patients with physiological types of occlusion, generalized chronic periodontitis and premature occlusal contacts (Group 2). Functional methods included electronic registration of occlusal relationships with the T-Scan® III computer occlusion analysis system and study of the bioelectrical activity of the masticatory muscles using the Bio-EMG® III electromyography using standard functional tests.

Results. In patients of group 2, in comparison with patients of group 1, neuromuscular discoordination of the functional activity of the masticatory muscles was diagnosed. This condition is confirmed by the asymmetry and lack of muscle synergy when performing the “Maximum volitional compression” test, an improvement in the symmetry of the work of the muscles of the same name on the right and left sides and the synergy of the work of the muscles of the right and left masticatory groups, as well as a statistically significant increase in the values of biopotentials m. temporalis and m. masseter during the “Maximum volitional compression on rollers” test.

Conclusions. Disturbances in the coordinated work of the muscles of the craniofacial region in patients with chronic generalized periodontitis and premature occlusal contacts are realized in a statistically significant increase in the biopotentials of the masticatory muscle group at rest, a decrease in biopotentials during functional loading, as well as a reduction in the values of symmetry and synergy in relation to similar values patients of group 1.

Published: May 2024

У статті розглядяться історія виникнення Товариства взаємного страхування від вогню в місті Харкові як одного з найстаріших подібних об’єднань Наддніпрянщини в кінці ХІХ ст. Особливу увагу автор приділяє організаційній структурі товариства, його управлінню та фінансовій діяльності. Аналіз діяльності та організаційних принципів існування Товариств взаємного страхування дозволяє висвітлити побут українського міста тієї епохи та стан соціальної підтримки міського населення. Вивчення вітчизняних традицій системи взаємного страхування майна від пожеж є важливим у процесі становлення та подальшого удосконалення сучасної системи соціальної підтримки населення, у тому числі економічного захисту населення від збитків, нанесених пожежами, бойовими діями, природними катаклізмами тощо. Тому історичний аналіз розвитку страхування може дозволити уникнути фатальних помилок у його подальшому становленні та майбутньому розвиткові нашої країни.
Одеса під владою червоних «військових начальників»: особливості військової окупації Одещини (квітень 1919 р.)
Authors: Савченко Віктор
Published: May 2024

Стаття присвячена аналізу формування московської військової диктатури в Одесі у квітні 1919 р., процесу формування армії «вторгнення» – 3-ї Української радянської армії, яку Москва планувала використати для війни проти Румунії та «походу на Європу». Московський колоніалізм проявився у тому, що всі владні рішення приймалися «посланцями Москви», які формували військові структури, надзвичайні методи влади, відсторонивши від прийняття владних рішень місцеве самоврядування та ради. Військові структури червоної армії в Україні формувалися з місцевих повстанців, які були введені в оману примарними обіцянками більшовиків. На плечі повстанців та їхніх ватажків сідали нові господарі життя – московські більшовицькі керівники та червоні військові командири, що перетворювали життя в містах і селах України на надзвичайний військовий режим. У той же час ці «лідери охласу» так і не змогли організувати на Півдні України чітку структуру військового командування та міської влади. Повний хаос в управлінні, «війна штабів», доповнювалася колонізаторською політикою червоних окупантів українських теренів. У квітні 1919 р. Україна була в стані гострого соціального, політичного та національного конфлікту, повстанці, з яких складалися частини 3-ї української радянської армії не підтримали утвердження «військового комунізму» й сама ця армія створювалася як примарне формування з вкрай завищеними показниками особистого складу.
3-я Українська радянська армія у хаосі самознищення (травень 1919 р.)
Authors: Савченко Віктор
Published: May 2024

Стаття присвячена аналізу подій на південному заході України пов’язаних з повстанням отамана Н. Григор’єва. Розглядаючи особливості російської агресії в Україні у 1919 р., треба зазначити, що російський колоніалізм, використовуючи оманливу пропаганду, спромігся залучити значну частину мешканців України до трьох червоних армій радянського Українського фронту. Але, в травні 1919 р. частини 3-ї армії цього фронту повстали проти колоніальної політики «червоної» влади. На Півдні України отаману Н. Григор’єву вдалося підняти на повстання не тільки свою 6-ту дивізію 3-ї армії, але й частини 5-ї дивізії, радянські гарнізони Миколаєва, Херсона, Очакова, невдала спроба повстання військових фіксувалася в Одесі. Можна твердити, що в середині травня 1919 р. 3-я армія Українського фронту опинилася в стані руйнації та хаосу, з якого вона так і не вийшла до своєї ліквідації у червні 1919 р. Повстання отамана Н. Григор’єва зруйнувала тили Червоної Армії, не давши їй змоги провести запланований «похід на Європу» (захоплення Румунії), зробивши її неспроможною опиратися наступу частин армії УНР і «білої» армії. Повстання показало силу українського спротиву «червоній» диктатурі та привела до загальної кризи владних інститутів, у той же час повстанці виявили свої вади: антисемітизм, що досяг рівня погромів, недисциплінованість частин, хаотичність військового стратегічного планування.

Este estudo visa compreender: como se dá o desenvolvimento das habilidades referentes ao sistema numérico decimal descritas na BNCC, por parte de alunos concluintes dos anos iniciais do ensino fundamental? Para tanto, foi realizada, inicialmente, uma revisão bibliográfica para explicitar sobre os principais sistemas numéricos até a ascensão do sistema decimal no Ocidente, culminando na sua inserção no Ensino Formal. Recorreu-se à pesquisa exploratória para entender como o conhecimento sobre sistema de numeração decimal se realiza em sala de aula, atrelado à BNCC. A análise dos dados produzidos se deu com a metodologia Análise Textual Discursiva, a partir da qual foram estabelecidas três categorias, quais sejam: habilidades desenvolvidas no trabalho com o sistema de numeração decimal; dificuldades observadas no trabalho com o sistema numérico decimal; ensino do sistema numérico decimal. Tais categorias dizem da pergunta de pesquisa e, portanto, uma asserção articulada sobre elas é um modo de tecer compreensões sobre oi que aqui se interroga.

O presente trabalho é fruto de uma prática pedagógica adotada durante a pandemia ocasionada pelo Coronavírus. Nosso objetivo é trazer algumas reflexões sobre o processo de autoria de alunos do 6º ano do Ensino Fundamental II, de uma escola da rede privada de Belo Horizonte – MG, durante as aulas remotas de Matemática ocorridas no primeiro semestre de 2021. Utilizou-se como aporte teórico o processo de autoria e jogos propostos por Demo (2009). Os alunos foram convidados a criar jogos na plataforma Kahoot! a partir de conteúdos matemáticos pré-estabelecidos pela professora e apresentar nas aulas para que seus pares jogassem. Os resultados mostraram que as aulas com o Kahoot! ficaram mais interativas, envolventes e motivadoras. Além disso, durante as partidas, a professora pode verificar as dificuldades encontradas pelos jogadores e pelo autor do jogo nos conteúdos abordados.

The genus Serratia harbors opportunistic pathogenic species, among which Serratia marcescens is pathogenic for honeybees although little studied. Recently, virulent strains of S. marcescens colonizing the Varroa destructor mite’s mouth were found vectored into the honeybee body, leading to septicemia and death. Serratia also occurs as an opportunistic pathogen in the honeybee’s gut with a low absolute abundance. The Serratia population seems controlled by the host immune system, but its presence may represent a hidden threat, ready to arise when honeybees are weakened by biotic and abiotic stressors. To shed light on the Serratia pathogen, this research aims at studying Serratia’s development dynamics in the honeybee body and its interactions with the co-occurring fungal pathogen Vairimorpha ceranae. Firstly, the degree of pathogenicity and the ability to permeate the gut epithelial barrier of three Serratia strains, isolated from honeybees and belonging to different species (S. marcescens, Serratia liquefaciens, and Serratia nematodiphila), were assessed by artificial inoculation of newborn honeybees with different Serratia doses (104, 106, and 108 cells/mL). The absolute abundance of Serratia in the gut and in the hemocoel was assessed in qPCR with primers targeting the luxS gene. Moreover, the absolute abundance of Serratia was assessed in the gut of honeybees infected with V. ceranae at different development stages and supplied with beneficial microorganisms and fumagillin. Our results showed that all tested Serratia strains could pass through the gut epithelial barrier and proliferate in the hemocoel, with S. marcescens being the most pathogenic. Moreover, under cage conditions, Serratia better proliferates when a V. ceranae infection is co-occurring, with a positive and significant correlation. Finally, fumagillin and some of the tested beneficial microorganisms could control both Serratia and Vairimorpha development. Our findings suggest a correlation between the two pathogens under laboratory conditions, a co-occurring infection that should be taken into consideration by researches when testing antimicrobial compounds active against V. ceranae, and the related honeybees survival rate. Moreover, our findings suggest a positive control of Serratia by the environmental microorganism Apilactobacillus kunkeei in a in vivo model, confirming the potential of this specie as beneficial bacteria for honeybees.

Introduction

Little is known about the proteomic changes at the portals of entry in rainbow trout after infection with the myxozoan parasites, Myxobolus cerebralis, and Tetracapsuloides bryosalmonae. Whirling disease (WD) is a severe disease of salmonids, caused by the myxosporean M. cerebralis, while, proliferative kidney disease (PKD) is caused by T. bryosalmonae, which instead belongs to the class Malacosporea. Climate change is providing more suitable conditions for myxozoan parasites lifecycle, posing a high risk to salmonid aquaculture and contributing to the decline of wild trout populations in North America and Europe. Therefore, the aim of this study was to provide the first proteomic profiles of the host in the search for evasion strategies during single and coinfection with M. cerebralis and T. bryosalmonae.

Methods

One group of fish was initially infected with M. cerebralis and another group with T. bryosalmonae. After 30 days, half of the fish in each group were co-infected with the other parasite. Using a quantitative proteomic approach, we investigated proteomic changes in the caudal fins and gills of rainbow trout before and after co-infection.

Results

In the caudal fins, 16 proteins were differentially regulated post exposure to M. cerebralis, whereas 27 proteins were differentially modulated in the gills of the infected rainbow trout post exposure to T. bryosalmonae. After co-infection, 4 proteins involved in parasite recognition and the regulation of host immune responses were differentially modulated between the groups in the caudal fin. In the gills, 11 proteins involved in parasite recognition and host immunity, including 4 myxozoan proteins predicted to be virulence factors, were differentially modulated.

Discussion

The results of this study increase our knowledge on rainbow trout co-infections by myxozoan parasites and rainbow trout immune responses against myxozoans at the portals of entry, supporting a better understanding of these host-parasite interactions.
