Automutilação na adolescência e vivência escolar: uma revisão integrativa da literatura
Authors: Lara Gianna de , Saraiva Eduardo Steindorf , Cossul Danielli
Published: February 2023

Resumo O objetivo deste estudo consiste em revisar as produções acadêmicas publicadas nos últimos dez anos, sobre a automutilação na adolescência e suas repercussões na vivência escolar. A metodologia utilizada foi a revisão integrativa da literatura a partir das bases de dados Scielo e Scopus. Como resultados, destaca-se a identificação de 13 artigos, os quais foram analisados através das categorias: i) perspectiva do professor, tendo como base os desafios enfrentados e as contribuições do contexto escolar em casos de automutilação; e ii) fatores desencadeantes relacionados à automutilação. Conclui-se que para os adolescentes o ato de automutilar-se é uma forma de comunicação consigo mesmos e com os outros, sendo um movimento solitário e ao mesmo tempo sinalizador do sofrimento psíquico que estão vivenciando, o qual pode ser observado e experienciado de diversas formas. A palavra, o gesto, a vivência e as atitudes como um todo, individuais e coletivas, são consideradas como fatores geradores tanto da aceitação de suas questões psíquicas, como ocasionadores do ato de auto mutilar-se. Nesse sentido, a percepção da família e do professor tornou-se um movimento importante, na visão dos adolescentes, pois ambos têm condições de ajudá-los, oferecendo suporte, apoio, acolhimento e escuta, essenciais para enfrentarem o período conturbado que estão vivendo.
ANÁLISIS DE LAS POLÍTICAS PÚBLICAS IMPLEMENTADAS SOBRE LA PREVALENCIA DE ECNT Y SU RELACIÓN CON EL SEDENTARISMO EN CHILE.
Authors: MUÑOZ FRANCISCO JAVIER RETAMALES
Published: February 2023

Las políticas públicas respecto a la prevalencia de ECNT (enfermades crónicas no transmisibles) en Chile responden a una necesidad constante y propia de las sociedades actuales por mantener el estado de bienestar de sus habitantes; sumado a esta complejidad se encuentra el sedentarismo como factor asociado y que repercute notoriamente en la población sin mediar en las condiciones etarias, sociales o económicas. Los efectos de las políticas públicas implementadas entre los años 2000 y la actualidad, buscan de forma transversal minimizar el impacto en la salud de la población, a razón de esfuerzos interministeriales, gubernamentales que, con una mirada local, pero con la interpretación funcional de la región y sus principales indicadores pretende soslayar este flagelo. Si bien el desarrollo de políticas públicas argumenta la preocupación de los Estados, estas medidas y regulaciones deben mantener una cuota de correlación entre áreas multidisciplinares, como así dimensionar nuevos panoramas o efectos adversos que puedan surgir como lo ocurrido con las pandemia de COVID-19 recientemente, que han impactado fuertemente en la actualidad la prevalencia de las ECNT por sobre otros FR (factores de riesgo) y en especial el sedentarismo dentro del ámbito comportamental siendo una causa directa de la carga de enfermedad y por ende factor en la tasa de mortalidad global por ECNT en el Chile; efectos que necesariamente deberán estudiarse en mayor profundidad en nuevos estudios.

The paper analyzes the reaction of phase formation occurring during the synthesis in the Al-TiO2 system. The problem of the phase composition change in the vicinity of the particles, where the change of the regions occupied by the phases is related to the moving boundaries, is formulated. An approximate analytical solution is constructed. Kinetic regularities of the strengthening particle formation and the matrix composition evolution in its vicinity have been studied under the assumption that the reactions start at a temperature higher than the melting temperature of aluminum, which surrounds the titanium oxide solid particles. The temperature is a function of the time and follows from the solution of the macro problem. The accompanying stresses and strains both in the vicinity of the interface and averaged over the cell volume are evaluated. During cooling both diffusion and reactions are inhibited, which leads to slowing down the growth of stresses, however, their values remain rather high.

IMPLEMENTATION OF STRATEGIC INFRASTRUCTURE PROJECTS: MODELING OF EFFECTS AND RESULTS
Authors: Prikhodko L. V. , Arsenova E. V.
Published: February 2023

The article describes the modelling of strategic infrastructure project effects and results using methods of analysing direct and indirect effects and helping to determine the feasibility of railway infrastructure project implementation. Neglecting this fact significantly reduces the overall efficiency of infrastructure projects, and in some cases leads to the wrong decisions that reject project implementation.

Investigations made by authors allow to identify, classify and quantitatively estimate the direct and indirect effects from the implementation of infrastructure projects, including integrated assessment of budgetary efficiency and an assessment of economic effects for the development of territories.

Among indirect effects the special attention was paid to the multimodal effects resulting from the redistribution of passenger and cargo flows and more rational capacity of the transportation system. The attention was paid to the multiplier effects caused in related sectors of the economy, agglomeration effects leading to increased connectivity of urban and suburban areas and the corresponding growth in employment, investment and productivity, the effects of optimising subsidies, etc.

Scenario forecasting procedures were used within the presented investigations. Macroeconomic effects, bottlenecks in the railway system impact on the level of undertransportation of goods as well as price arbitrage were determined for various scenarios.

One of the features of the development of modern society is the growing need to restrict access to various objects. The main task of the State Border Guard is to ensure the inviolability of the state border, including the prevention of illegal crossing of the state border. Nowadays, presence detection systems are often used for this purpose - devices or functions of a security television system that generate an alarm when movement is detected in the field of view of the camcorder. The aim of the current study is to analyze the efficiency of the use of presence detection systems used in the structural units of the State Border Guard.
What do teachers have to do with it?
Authors:   , Elliott Kathlyn Elizabeth , Kelly Kristy E
Published: February 2023

This research investigates how teachers in Finland understand their role in the prevention of violent extremism. Finland's first National Plan was adopted in 2016 in response to calls from the UN to help prevent violent extremism and were a response to increased homegrown Islamic terrorism associated with ISIS and other Islamic extremist organizations (Ministry of the Interior, 2016). The most recent version of the plan includes education as part of a broad-based, public health approach to prevention (Ministry of the Interior, 2019). Through a qualitative ethnographic approach, I look to examine how education works in concert with other aspects of the Finnish welfare system and how teachers make sense of their role in the prevention of violent extremism. The Finnish welfare state acts a primordial prevention where the systems create a society that focuses caring for their citizens and protecting them from economic and social situations that create vulnerabilities to extremist ideologies and use of violence. Most teachers feel that the prevention of violent extremism is part of their responsibilities, but with reservations and concerns expressed about the increasing level of expectations placed on teachers. Teachers are able to identify individual-level risk factors, but struggle to correctly identify communitylevel and societal-level risk factors. In the classroom, teachers and administrators are able to identify school-based programs and systems, curriculum, and pedagogy that would help in the work of preventing violent extremism. This work addresses a significant gap in understanding how teachers as street-level bureaucrats understand their role and see examples of how their daily practice can be used as preventative measures.

Authors:   , Featherstone Bryan Scott , Gonder Mary K , Russell Jacob A
Published: February 2023

Habitat loss, forest fragmentation, and growing anthropogenic pressures are recognized as driving factors in the loss of biodiversity and increased extinction rates of wildlife populations on a global scale. The Gulf of Guinea rainforests in Central West Africa are considered to be biodiversity hotspots of global importance due to high levels of species richness and endemism, this region hosts a large portion of the world's flora and fauna, and large swaths of forest areas remain largely intact. However, Central Africa continues to experience rapid human population growth, which has led to an alarming increase in biodiversity loss through infrastructure expansion, deforestation, illegal hunting and accessibility, to pristine habitats. Despite the importance of these forests, the impacts of these anthropogenic pressures on biodiversity remain poorly understood. This study aims to disentangle and more accurately understand the impacts of environmental changes and anthropogenic pressures on vulnerable large mammal populations to create a science driven science driven conservation efforts by using utilizing multidisciplinary datasets and modeling techniques. The datasets included in this study are 16S rRNA amplicon sequences from fecal material of six primates found on Bioko Island, Equatorial Guinea, climatic, topographic and anthropogenic predictor variables compiled from remote sensing databases across Bioko Island, presence localities of primates, duikers and hunting signs from biomonitoring surveys over a 10+ year time period, carcass rates from the central wildlife market in the capitol city of Malabo, and hunter surveys spanning several villages along the southern portion of Bioko Island. The aims of this study are to; (1) identify the major factors driving GMC variation in six primate species inhabiting Bioko Island; (2) investigate the impact of micro-environmental and anthropogenic variables on the GMC variation found within the Bioko Drill; and, (3) determine the impacts of hunting pressures, market dynamics and hunter motivations have on large mammal vulnerability on Bioko.

Published: February 2023

El objetivo del presente artículo es analizar una serie de programas de turismo social promovidos durante el Frente Popular chileno (1938-1946) que permitieron que un número creciente de trabajadores pudieran acceder a la experiencia de las vacaciones y el tiempo libre. Un aspecto a destacar es el papel que desempeñó el Estado, así como los municipios y empresarios, en la formulación de iniciativas como las colonias de verano para obreros. Se finaliza con la Dirección General de Informaciones y Cultura (1942) como punto de inflexión en la formulación de programas de turismo social. Se concluye que estas acciones promovidas por los gobiernos del Frente Popular fueron un avance en las políticas sociales de inclusión para los trabajadores y sirvieron de modelo para futuros programas de turismo social en Chile.
Internações por condições sensíveis a atenção primária: revisão qualitativa da literatura científica brasileira.
Authors: Malvezzi Edson
Published: February 2023

O Sistema Único de Saúde vem enfrentando a fragmentação do cuidado com a formulação de propostas que visam a integração e a integralidade das ofertas de serviços e ações de cuidado centrados nas necessidades de saúde da população. Uma destas é a adoção da Atenção Primária em Saúde como ordenadora do sistema, buscando a racionalidade e coordenação na utilização dos demais níveis assistenciais. Um dos grandes desafios é a integração entre os serviços, onde se destaca o distanciamento entre as Unidades Básicas de Saúde e os Hospitais. Neste sentido, um conceito que vem sendo utilizado para avaliar esta relação é o de Internações por Condições Sensíveis à Atenção Primária. Este trabalho tem como objetivo explorar as diferentes abordagens e apresentar os sentidos e usos atribuídos ao indicador ICSAP no Brasil, através de uma revisão da literatura nacional, de cunho qualitativo, entendida como um estudo exploratório da produção do conhecimento acerca do tema, privilegiando-se o artigo científico como fonte de análise. Os resultados apontam para a importância que o uso deste indicador vem ganhando na avaliação da Atenção Primária, porém com alguns aspectos ainda a serem superados para seu uso, tais como a sua formula de cálculo e acesso ao banco de dados, e de que não há consenso sobre a correlação inversa entre a cobertura da Atenção Primária e as ocorrências de internações por CSAP.
Gestação na adolescência e transtorno depressivo: desafios à atenção básica, às redes de cuidado e à educação na saúde
Authors: Moraes Maurício , Ceccim Ricardo Burg
Published: February 2023

O artigo é resultado de uma pesquisa realizada com 136 puérperas captadas de uma coorte de 540 gestantes adolescentes inscritas na rede básica de saúde. Essas adolescentes foram classificadas quanto à presença ou não de transtorno de depressão. Um questionário composto de perguntas abertas foi aplicado em entrevista, tendo sido categorizadas vinte variáveis que diziam respeito à vida adolescente e ao contato com os serviços de saúde. Pela prevalência de 18,4% do diagnóstico de depressão, estabeleceu-se, como paralelo, significados para o cuidado em saúde de puérperas que possuíam diagnóstico de depressão maior na gestação e puérperas que não tinham este diagnóstico. Foram detectados fatores, tanto de cobrança pessoal, como de pressão social, uma vez que as jovens se identificaram antes da gravidez como “irresponsáveis” ou “imaturas” e relataram, após a gravidez, o “amadurecimento pessoal”, como identidade. Do ponto de vista pessoal, as adolescentes com depressão na gestação se perceberam “mais responsáveis” após o nascimento dos filhos, enquanto as demais se perceberam “mais felizes”. A participação solidária da mãe ou do pai das adolescentes, assim como do namorado e da sogra foi proporcionalmente maior quando comparada com aquelas que não apresentaram depressão, o que diz de as adolescentes com depressão terem contado com proteção e cuidados especiais, atenuando, por conseguinte, sua eventual exposição ao maior risco psicossocial.

Published: February 2023

Relevance. The survival and reproductive rates of mini-tubers obtained from in vitro potato plantlets were observed to increase under greenhouse conditions. This increase was diagrammed based on the experimental data. The aim of the study was to assess the effect of various types of bio-soils on the multiplication factor of mini-potatoes in vitro at the stage of original seed production in protected ground conditions.

Materials and methods. The research was conducted in FSBSI “Federal Scientific Center of Agricultural Biotechnology of the Far East named after A.K. Chaiki” (Timiryazevsky settlement, Ussuriysk urban district, Primorsky kray) in 2021.In vitroplantlets of four potato varieties from different maturity groups were used as the research object: Meteor (early), Sante (medium early), Dachnyi (mid-season), and Smak (medium late). These potato varieties were admitted to use in the 12th (Far Eastern) region. The experiments were carried out in a 260 m2 greenhouse during spring and summer. Five variants of potting soil were studied. An agrochemical analysis of the soil mixtures was performed in the Laboratory of Agrochemical Analyses according to generally accepted methods. The reproductive rate of a variety was calculated from the number of survived plants in vials: the total reproductive rate and the reproductive rate of standard tubers (according to GOST 33996-2016). For this purpose, potato sizing squares and the visual method for the rejection of defective material were implemented.

Results. Three out of five studied soil mixtures were determined to be effective for four potato varieties used in the experiments: a) 70% peat, 20% biocompost, and 10% vermiculite; b) 60% peat, 30% humus, and 10% sand; c) 60% peat, 20% humus, 10% humus from seaweeds, and 10% vermiculite.

Published: February 2023

The vegetable growing industry in Russia is the main component of crop production, the development of which determines the basis of life and food security. Being the most important and indispensable products of plant origin in the human diet, for a Russian, vegetables are in third place in importance after bread and potatoes. However, according to Rosstat, the level of selfsufficiency in vegetables and food melons in the country is 86,3%, which implies the need to increase their production. To improve the situation in the vegetable growing industry, an important place is given to the issues of improving selection and seed production, since the variety and high-quality seeds are the main elements of modern zonal crop cultivation technologies. At the Federal Scientific Center for Vegetable Growing, selection and seed production of vegetable crops is moving to an innovative development path, where, along with classical methods, modern methods are used: molecular marking according to the main economic characteristics, accelerated creation of homozygous lines using doubled haploid methods, plant immunity. In recent years, various methods of pre-sowing preparation of seeds have been developed to increase their viability and germination friendliness, to obtain even seedlings without harming the ecosystem. Based on the fundamental and priority applied research of previous years, in 2022, the creation of 17 varieties and hybrids of vegetable, melon and flower crops for all potential vegetable growing zones was completed. In order to provide the industry with pure-grade high-quality seed and increase the productivity of crops through the full use of the potential of the variety, the Federal Research Center for Vegetable Growing is constantly working in primary seed production. The developed zonal cultivation technologies will allow growing domestic products in various soil and climatic conditions of the country.
Assessment of early ripeness and productive capacity of a collection of F1 hybrids of cucumber grown in a polycarbonate greenhouse in the south of the Amur region
Authors: Kositsyna O. A. , Kirsanova V. F.
Published: February 2023

Relevance. In the vegetable market, cucumber is in stable demand. It also occupies one of the leading places in the structure of sown areas after root crops, cabbage, and tomato. In addition to high yields, modern varieties (hybrids) of cucumber, are characterized by good marketability of green cukes and transportability. The stable demand for green cukes among the population, as well as their high economically valuable characteristics, ensure constant interest in this crop both at large and small farms, which supply a significant part of the market with the fresh produce in spring and summer. Local peasant farms grow cabbages, root vegetables, onions, and watermelons, but very few of those cultivate cucumbers. Those are mainly grown in spring greenhouses. This imbalance is explained by the lack of cucumber varieties and hybrids adapted to local conditions.

The purpose of this study is the assessment of a collection of parthenocarpic F1 cucumber hybrids and identification of highly productive varieties suitable for growing in polycarbonate greenhouses suitable in the spring-summer rotation in the south of the Amur Region. The object of the study were 11 F1 cucumber hybrids of domestic and foreign selection.

Results. According to the results of studying the collection of parthenocarpic hybrids of cucumber grown in spring/summer polycarbonate greenhouses in the south of the Amur Region, marketable green cukes are formed on day 44-54 after germination. The hybrids Amur F1, Artist F1, Director F1, Componist RZ F1, Bjorn F1, Gunnar F1, and Cedric F1 are characterized by high productive facility. They have formed 9.0–13.0 kg/m2 of marketable green cukes. According to the test panel score, the hybrids Bettina F1, Pasalimo F1, and Gunnar F1, have the best gustatory quality (4,8-5,0 points).

Published: February 2023

Relevance. Pumpkin is a food, medicinal and fodder crop of the Cucurbitaceae family. It is valued for its high content of vitamins, minerals, organic acids. At present, thanks to the huge variety of species and modern selection, it is possible to select pumpkin varieties for cultivation in almost any region, including areas with short and not too hot summers. Udmurtia belongs to the zone of risky farming, the end of spring frosts is observed on average in the first ten days of June, and autumn frosts on the soil are possible at the end of August. Due to the short frost-free period, it is necessary to choose earlier maturing varieties, grow the crop through seedlings and use temporary shelters. The pumpkin fruit is usually large in size, is a thick layer of pulp, covered with a dense peel. When cutting such a fruit, the pumpkin is not stored in the future, it requires urgent processing. In this connection, in recent years, portioned varieties of pumpkin, the size of the fruit of which does not exceed 1.5–3.0 kg, have become increasingly in demand.

Materials and Methods. The purpose of the research: a comparative assessment of varietal characteristics of growth and productivity of pumpkin species. In 2020–2021 in the conditions of the Udmurt Republic, experiments were carried out to study the characteristics of growth and productivity of pumpkin varieties. We studied varieties of pumpkin: Pearl, Crumb, Honey Tale, Marble, Rossiyanka, Smile, Candied fruit.

Results and its discussion. Within two years, pumpkin varieties of large-fruited and nutmeg were studied. On average, for two years, the pumpkin Medovaya skazka distinguished itself with the highest yield. In 2021, the yield for the Medovaya Skazka variety was 64.7 t/ha. The yield increase was obtained due to an increase in fruit weight, which in 2020 amounted to 2.9 kg, in 2021 - 6.5 kg. The studied varieties of pumpkin differed in quality indicators of fruits. On average, over two years, the varieties Rossiyanka and Mramornaya showed an increase in the content of water-soluble sugars in fruits. The fruits of the pumpkin Candied fruit and Kroshka were distinguished by a high content of dry matter.

Authors: DİLBAZ Kübra , ALDEMİR Oya , DİLBAZ Serdar , DİLBAZ Berna , ÖZELÇİ Runa , USTUN Yaprak
Published: February 2023

Aim: Hypogonadotropic hypogonadism (HH) is a rare clinical condition resulting from gonadal insufficiency due to low pituitary gonadotropin levels. Since ovulation occurs rarely in these patients, the probability of spontaneous pregnancy is very low. The study aimed to evaluate the in vitro fertilization (IVF) treatment outcomes in patients with HH and to compare these results with that of patients with unexplained infertility (UI) who underwent IVF treatment.
Material and Methods: In this study, 36 cycles of 28 HH patients who underwent IVF treatment and 72 cycles of 68 patients who underwent IVF treatment for UI were included. Demographic data, ovarian hyperstimulation and cycle outcomes, clinical pregnancy rates, and predictive factors for clinical pregnancy were evaluated retrospectively, and the two groups were compared.
Results: In the HH group, clinical pregnancy, and live birth rates per cycle after IVF were significantly higher compared with the UI group (n=16, 44.4% vs. n=17, 23.6%, p=0.027; and n=14, 38.9% vs. n=14, 19.4%; p=0.030, respectively). Although the number of antral follicles (p=0.001) and retrieved oocytes (p=0.042) were significantly higher in the UI group, the number of mature oocytes and grade I-II embryos were similar in the HH and UI groups. The total gonadotropin dose used and duration of stimulation in the HH group were significantly higher than in the UI group (both p=0.001).
Conclusion: HH patients responded well to IVF treatment and had better IVF outcomes compared to women who underwent IVF for UI. No prognostic factor that affected pregnancy success in HH patients was detected.

Authors: Marčun Varda Nataša , Hanželj Natalija
Published: February 2023

Purpose: The purpose of our research was to determine the prevalence of overweight and obese school children 6-15 years of age. We wanted to determine the children´s knowledge about obesity and treatment for obesity. We also wanted to raise awareness about obesity as a chronic disease. The results of the current could facilitate targeting prevention activities.

Methods: The study included 966 children, 6-15 years of age, from different primary schools in Slovenia. The study was conducted from 2012-2013 using a questionnaire to acquire epidemiologic information about overweight children and was processed using basic statistical methods with SPSS.

Results: We showed that 12.7% of children were overweight; 8.4% of children were in the overweightcategory and 4.3% were in the obese category. Of the enrolled children, 77% were of the opinion that their eating habits were suitable, despite the fact that only 66% had 5 meals per day and 61% had breakfast every day. One-half of the children claimed to be physically active and 70% were sedentary < 2 h daily.

Conclusion: With respect to excessive nourishment of children, Slovenia ranks lower than other countries. Knowledge about obesity as a chronic disease among Slovenian school children was limited, as was knowledge about different treatments for obesity. Thus, there is a public health need to preventchildhood obesity.
Lactobacillus plantarum PCS 26 as a probiotic dietary supplement in Slovenian patients with metabolic syndrome: a pilot clinical study
Authors: Gorenjak Mario , Škorjanc Dejan , Skok Pavel
Published: February 2023

Purpose: In this study, we aimed to determine the effect of a probiotic dietary supplement on physical-anthropometric and biochemical markers in Slovenian patients with metabolic syndrome.

Methods: This prospective, randomized, double-blind, placebo-controlled pilot clinical trial involved 16 volunteers who consumed a probiotic dietary supplement over a period of 3 months. The volunteers underwent clinical assessments before and at the end of the period of consuming the dietary supplement or placebo.

Results: At a concentration of 1 × 109 colony-forming units per day (N = 8), the Lactobacillus plantarum PCS 26 supplement decreased waist circumference (p = 0.043), lowered serum cholesterol (p = 0.028), and maintained serum adiponectin levels (p = 0.629). In the group that received the placebo (N = 8), no differences were found in the waist circumference (p = 0.750) or serum cholesterol levels (p = 0.225); however, we found a statistically significant reduction of the serum adiponectin levels (p = 0.036).

Conclusion: Although the number of patients examined was too low to draw any firm conclusions, dietary supplementation with the probiotic strain Lactobacillus plantarum PCS 26 exerted some favorable effects that could alleviate the symptoms of metabolic syndrome and reduce the clinical manifestations and risks of cardiovascular diseases. These results represent a starting point to carry out an extensive long-term clinical trial that would provide insight into the mechanisms of action of probiotic bacteria in preventing or relieving metabolic syndrome or its components.
Is Fabry disease an indication for a transcatheter aortic valve implantation? A case of successful surgical aortic valve replacement with an adverse postoperative course
Authors: Antonič Miha
Published: February 2023

Purpose: Fabry disease (FD) is an extremely rare X-linked lysosomal storage disorder caused by a deficiency of the enzyme α-galactosidase A, which results in intracellular accumulation of glycosphingolipids. In the heart, accumulating sphingolipids and accompanying fibrosis promote hypertrophy, conduction disturbances, thickening of the valves, and accelerated coronary artery disease resulting in substantial morbidity and mortality.

Case report: Here, we present a case of a 57-year old male with FD, severe aortic valve stenosis, and permanent atrial fibrillation who underwent successful and uncomplicated surgical aortic valve replacement, but postoperatively developed severe complications of nearly all organ systems, which resulted in death.

Conclusion: Although the patient risk profile did not meet the criteria for transcatheter aortic valve implantation, this treatment option is presented and discussed as a possible or even preferable alternative to surgery.

Authors: Rižnik Petra , Bevc Sebastijan
Published: February 2023

The Faculty of Medicine at the University of Maribor is the younger of the two medical faculties in Slovenia. Since its foundation, it has been successfully engaging students in the educational process. The result of students ´ involvement is the introduction of peer teaching, and along with that, the incorporation of objective structured clinical examination (OSCE) as an assessment method. This paper focuses on the development of clinical skills peer teaching and its accompanying tool of assessment, OSCE, at the Faculty of Medicine, University of Maribor.
Systemic errors in clinical studies / Sistemske napake kliničnih raziskav
Authors: Pahor Dušica
Published: February 2023

Despite careful planning and implementation of clinical studies, systematic errors occurring during the course of the research cannot be avoided. In a clinical study, such errors can lead to conclusions that are not realistic. These errors can be increased, minimized or even reversed. Finding the cause and scope of such errors are of exceptional importance in a clinical study. The greater the systematic error or 'bias', the greater the possibility for erroneous statistical results becomes. Systematic errors are, therefore, a constant danger for clinical studies. A study is considered to be unsuitable if at least one systematic error is present.

Authors: Bergauer Andrej , Prosen Gregor , Kobilica Nina , Flis Vojko , Jevšek Marko , Šeruga Tomaž
Published: February 2023

Purpose: The present proof of concept study was performed to evaluate the consistency between measurements of the optic nerve sheath taken using contrast– enhanced sonography and high– resolution magnetic resonance imaging (MRI). The main goal was to devise a novel candidate method to measure the optic nerve sheath diameter that is easy to perform, straightforward to interpret, and highly reproducible.

Methods: The approval of the National Medical Ethics Committee of the Republic of Slovenia was obtained; the study was registered under No. 30/03/12. Nine healthy young adults were examined with high–resolution MRI and contrast–enhanced ultrasound (CEUS). Measurements of the optic nerve sheath diameter were performed 3 mm behind the bulb, using both methods. The datasets were anonymized and the readers, blinded. Statistical analysis included evaluation of agreement using Bland–Altman plots. The assessment of inter– rater reliability was achieved by calculation of the intra class correlation coefficient.

Results: Bland–Altman plots showed favorable overall agreement between both methods, with clinically acceptable limits of agreement. The intra class correlation coefficient calculated for both methods suggests that the CEUS method was at least as reproducible as high–resolution MRI.

Conclusion: The described method, using CEUS to measure the optic nerve sheath diameter, facilitates the identification of the surrounding anatomy. When CEUS is employed, the measurement points can be easily and reliably set, and retro bulbar artifacts are less confounding. Based on results from a relatively small sample, this method seems to be comparable with high–resolution MRI. Evaluation of the method on a larger sample of healthy subjects and patients with increased intracranial pressure is needed.
Assessment of left ventricular impairment by calculating left ventricular impairment index using doppler echocardiography in chronic heart failure patients
Authors: Krajnc Igor , Sinkovič Andreja
Published: February 2023

Purpose: In order to assess global left ventricular impairment in chronic heart failure (HF) patients, it is necessary to consider both functional and structural changes of the left ventricle (LV), in particular, stroke volume (SV) and left ventricular end-diastolic diameter (LVEDD). Based on SV as a marker of LV function, LVEDD as a simple indicator of structural LV changes, and height of an individual patient (H), the left ventricular impairment index (iLVI) can be calculated. The purpose of this study was to assess the diagnostic value of iLVI in chronic HF patients.

Methods: This prospective study included a total of 50 chronic HF patients and 50 healthy individuals, whounderwent standard two-dimensional echocardiography. The iLVI was calculated according to the formula: iLVI = SV x H / LVEDD2 (mL/cm). Results:The iLVI accurately separated healthy subjects from patients (AUC = 0.989), with the highest sensitivity and specificity for proper identification of HF (96.0% each),in comparison with ejection fraction (EF), stroke volume index (SVI), and SV/H. The iLVI effect was strong (Cohen’s d=3.2), exceeding that of EF, SVI, and SV/H.

Conclusion: The study concluded that the iLVI, which can be readily calculated, represents an excellent clinical marker for global functional and/or structural LV impairment in chronic HF patients.
How and why to analyze microbiota – a quick guide for clinicians
Authors: Horvat Sabina , Rupnik Maja
Published: February 2023

Microbiota is defined as a microbial population inhabiting a given body part. The best known example is the gut microbiota, but oral, vaginal, and skin microbiota have also been studied extensively. Many body parts previously thought to be sterile have been shown to possess their own specific microbiota. Each microbiota plays an important role in organ functioning, in health, or in disease development. Therefore, microbiotas are widely studied in an effort to establish possible health or disease markers, or to use microbiota as potential therapeutic targets. The literature on microbiota has increased exponentially along with the development of methods used for analysis. An understanding of the basic principles and terms used in microbiota studies are therefore an important part of a clinician’s education.
A Novel Capacitive Method for Urodynamic Measurements That is Suitable for Home Use
Authors: Nikolić Gregor , But Igor , Stožer Andraž , Kramberger Iztok
Published: February 2023

Purpose: Urinary incontinence is highly prevalent in both women and men. Urodynamic testing is essential for diagnosis, but a gap exists in the usefulness of simple assessments that do not provide sufficient data, and devices that provide the necessary data, but are used primarily in clinics and clinical trials. This study considered the existing methods of urodynamics testing and developed a device that was both effective and suitable for home use.

Methods: A review of existing urodynamic methods led to development of a capacitive device. We created a device with sensor electrodes placed on the outside of a specimen container. The functionality of the electrodes and performance of the novel capacitive device were compared with that of a gravimetric device (Dorado KT, Laborie Medical Technologies, Mississauga, ON, Canada) used at the University Clinical Center, Maribor.

Results: Measurements of fluid volume (p = 0.936), maximum (p = 0.327), and mean (p = 0.136) flow observed with the two devices were not significantly different. Graphical analysis of collected volumes and flow variation over time show a high degree of overlap.

Conclusion: Compared with previously developed urodynamics testing devices, the capacitance method and the performance of this device represent an advance. The precision of the measurements needs improvement and did not fully address the recommendations of the International Continence Society, but he use of additional sensor electrodes is expected to improve performance. Extending the functionality as a standalone capacitive device for home use and upgrading with wireless access by mobile systems would allow for additional benefits beyond current voiding diaries.
Percutaneous balloon aortic valvuloplasty: palliative treatment for inoperable patients?
Authors: Dovč Klemen , Markota Andrej , Kanič Vojko , Bombek Mirko , Prosen Gregor
Published: February 2023

Purpose: The number of elderly patients with severe aortic stenosis and comorbidities is increasing in the aging populations of “developed” countries. Unacceptably high perioperative mortality and morbidity makes the decision to undertake surgical aortic valve replacement in this group of patients difficult and unlikely. Development of less invasive procedures such as balloon aortic valvuloplasty and transcatheter aortic valve replacement is emerging as another treatment option.

Case report: A 84-year-old female with previous left-sided hemiparesis after stroke and severe aortic stenosis presented with pulmonary edema to our institution. Non-invasive ventilation and inotropic support were unsuccessful. Balloon aortic valvuloplasty was done as as emergency procedure and she improved immediately. She was discharged after 25 days of inhospital treatment. She died 8 weeks later of unrelated reasons (infected decubitus and sepsis).

Conclusion: Balloon aortic valvoluplasty might be used as temporary and interim therapeutical options for patients with severe aortic stenosis and acute left ventricular failure who have unacceptably high risks when aortic valve replacement or emergency transcatheter aortic valve implantation is considered. Balloon aortic valvuloplasty may be used as a bridge to both procedures.
Arthroscopic anatomy and pathoanatomy of anterior cruciate ligament ruptures: clinical study with 94 patients
Authors: Hussein Mohsen , Čretnik Andrej , Dinevski Dejan , Rupreht Mitja , Vogrin Matjaž
Published: February 2023

Purpose: To arthroscopically evaluate the size variability of the Anterior cruciate ligament (ACL) insertion sites and to determine whether there are variations in rupture patterns of the two ACL bundles.

Material and Methods: Ninetyfour patients undergoing ACL reconstruction between June 2008 and June 2009 were included inour study. The average age of the patients was 26.7 ± 8.3 years (range, 16–48 years). Only patients with an ACL rupture less than 120 days old were included as unpublished data revealed difficulty in distinguishing between AM and PL bundles in older ACL ruptures.

Results: The femoral ACL insertion site length ranged from 11 to 20 mm (15.9 ± 2.2). On the tibial side, the length of the tibial ACL insertion site ranged from 9 to 20 mm (16.0 ± 2.1). On the femoral side, the width of the ACL insertion site ranged from 6 to 11 mm (8.3 ± 1.2). On the tibial side, the width of the entire ACL insertion site ranged from 6 to 12 mm (8.7 ± 1.1). The most frequent injury pattern was found to be the proximal rupture of both bundles; seen in 74 patients (78.7%).

Conclusion: Both hypotheses were confirmed, and this may be clinically relevant in anatomic ACL reconstruction.
