Ferramenta para Análise e Gestão de Custos da Atividade Cafeeira em Pequenas e Médias Propriedades Rurais
Authors: Sacardo Luiz Felipe , Ramos Michele Ribeiro
Published: April 2021

ResumoO Agronegócio é responsável por cerca de ¼ das riquezas geradas anualmente no Brasil. Dentro deste universo a cultura cafeeira é responsável por cerca de 10% do volume total das exportações deste setor. A viabilidade da produção cafeeira em qualquer escala depende fortemente da agregação de qualidade no produto final, eficiência nos processos e o controle dos custos da atividade. Os pequenos e médios cafeicultores, de maneira geral, ainda carecem de uma estrutura administrativa que lhes permita conhecer e gerencia adequadamente suas finanças, apesar de existir uma consciência da necessidade do conhecimento e gerenciamento dos custos de produção o que ainda vemos são as finanças das atividades sendo misturadas com as finanças pessoais, impossibilitando qualquer tipo de análise precisa e ainda, uma forte tendência de subjugar os custos e despesas e de inflacionar os resultados finais, mesmo que estes não estejam explícitos. Fatores como má administração do fluxo de caixa ou até mesmo menosprezo por pequenas despesas no cálculo do resultado podem ser o diferencial entre aqueles produtores que prosperam e aqueles que têm de deixar a atividade.

Abstract Agribusiness is responsible for about ¼ of the wealth generated annually in Brazil. Within this universe, coffee culture is responsible for about 10% of the total export volume of this sector. The viability of coffee production on any scale strongly depends on the aggregation of quality in the final product, process efficiency and cost control of the activity. With the administrative modernization of the activity efficiency is gained, and with the efficiency gain opportunities for greater financial gain arise, either through cost reduction or revenue increase. Small and medium coffee farmers, in general, still lack an administrative structure that allows them to know and manage their finances properly, although there is an awareness of the need for knowledge and management of production costs. What we still see is the finances of the activity mixed with personal finances, precluding any kind of precise analysis and yet a strong tendency to subjugate costs and expenses and to inflate final results, even if they are not explicit. Factors such as poor cash flow management or even contempt for small expenses in calculating income may be the difference between those who thrive and those who have to leave the business.

Published: April 2021

ResumoO objetivo deste estudo exploratório é analisar a disposição dos consumidores brasileiros em utilizar a solução logística através de pontos de coleta para a retirada de medicamentos, itens de consumo recorrente e primordiais sobretudo no atual contexto de pandemia. Os pontos de coleta são locais físicos onde os consumidores podem retirar produtos comprados pela internet ou pelo telefone. Essa solução permite a utilização de uma rede de distribuição com armazenagem em fabricante ou distribuidor, resultando em menores custos logísticos. Por sua vez, os consumidores podem ser beneficiados, à medida que não precisam esperar pelas entregas, podendo receber suas encomendas antecipadamente e encontrar fretes mais acessíveis. Para a obtenção dos dados sobre as escolhas dos entrevistados aplicou-se um formulário integralmente online apresentando situações hipotéticas de entrega conforme a técnica de preferência declarada. Os resultados da pesquisa mostraram que a solução logística proposta pode ser viável, desde que apresente benefícios extras aos consumidores, se comparado à entrega convencional.

AbstractThe aim of this exploratory study is to analyze the willingness of Brazilian consumers to use the logistical solution through pick-up points for the withdrawal of medicines, items of recurrent consumption and essential, especially in the current context of the pandemic. Pick-up points are physical locations where consumers can collect products purchased over the internet or over the phone. This solution allows the use of a distribution network with storage at a manufacturer or distributor, resulting in lower logistics costs. In turn, consumers can benefit, as they do not have to wait for deliveries, being able to receive their orders in advance and find more affordable freight. To obtain data on the respondents' choices, a fully online form was applied showing hypothetical situations of delivery according to the declared preference technique. The research results showed that the proposed logistical solution can be viable, as long it presents extra benefits to consumers, when compared to conventional delivery.

Published: April 2021

ResumenEn el presente artículo, de naturaleza mixta, busca describir los conocimientos y los argumentos estadísticos que declaran futuros profesores de matemática de Educación Secundaria sobre situaciones aleatorias. Para ello, se analizó la percepción de 23 futuros profesores hacia la estadística, así como los argumentos entregados frente a dos situaciones aleatorias propuestas por Green (1989). La primera situación analiza la disposición entregada por cuatro estudiantes sobre la aparición de números del 1 al 16 en una cuadricula de 16 espacios. La segunda actividad evalúa si los vectores de datos del lanzamiento de 40 monedas realizadas por dos estudiantes se modelaban de manera aleatoria. Los resultados permitieron observar que los futuros profesores no declaran elementos teóricos acerca de los modelos estadísticos presentes en las actividades propuestas tendientes a tomar una decisión, como así también los argumentos entregados carecen de fundamentación teórica.

AbstractIn this article, mixed nature analyzes the perception of teachers in training towards statistics and the arguments given about two random situations to which they were subjected. Thus, the objective of the research was to describe the knowledge and statistical arguments about the random situations proposed by Green (1989). The study involved 23 teachers in training who had to answer two questions; the first was to study the provision given by four students of the appearance of numbers listed from 1 to 16 in a grid of 16 spaces. Similarly, the second activity consisted in evaluating whether the data vectors of the launch of 40 legal currencies made by two students were randomly modeled. The results allowed us to evaluate that the teachers in training do not present theoretical foundations about the statistical models present in the proposed activities tending to make a decision, as well as the arguments given lack theoretical foundation.

Eudaimonia: il ritorno agli antichi e degli antichi. Annotazioni attorno ad una proposta filosofica
Authors: Maraglino Giannicola
Published: April 2021

The study of 20th-century philosophical thought could prove to be of great interest if read in the light of its ethical-anthropological demands. In this sense, he cannot but turn with great interest to the philosophy of the American Martha Nussbaum. Specifically, the name of this philosopher should recall that cultural context of “analytical” philosophy. The intention of this contribution will be to seek the theoretical nodes of the renewed post-modern philosophical interest in the thought of the ancients and especially towards Aristotle. This is to the extent that such a look is the necessary foundation to support contemporary reflection on moral action.
Aristóteles e a Hierarquia dos Bens
Authors: Moraes Francisco
Published: April 2021

In this paper, I would like to presente the hierarchy of goods, supported by Aristotle in his ethical treaties and in Politics, as the solution to the impasse between two conceptions of virtue that come into open conflict in some of the main Platonic dialogues: virtue as sovereignity and self-sufficiency of the wise, such as that which opposes the insufficiency of addiction, and virtue as capacity ans achievement, as that which opposes to incapacity and to debility. I intend to show that Aristotle “saves” the aristocratic conception of virtue in the same extent that he defends pratical truth Against logical rigorismo, without, however, failing to incorporate the Platonic objection to an instrumental conception of virtue that sees it as a means for obtaining wealth and power.
« Expliquer le bien par une image ». Simone Weil et l’image platonicienne du Bien dans la République
Authors: Simeoni Francesca
Published: April 2021

In this contribution I aim to analyze how Simone Weil (1909-1943) interprets the image of the Good and the periagōghē of the soul described by Socrates in Plato’s Republic. In the first part, I consider the key role that Plato plays in the last writings of Weil. The Athenian philosopher, in fact, becomes a specific reference for Weil in the 1940s, within her attempt to reformulate an ethic for contemporaneity. In the second part, I analyze Weil’s specific comments on the Socratic image of the sun (Resp. VI 504a-509c) and on the last part of the myth of the cave (Resp. VII 518b-d). In the last part, I try to highlight Weil’s originality and her specific contribution : the author in fact frees herself from the Platonic text and follows an interpretative path that integrates the role of desire. She deviates from an intellectualist interpretation of the vision of the Good and pushes both the analogy of the sun and the exit of the prisoner outside the limits of nous.
Aristotle’s Account of Moral Perception (EN.VI.8) & Nussbaum’s Priority of the Particular Thesis
Authors: Hole Benjamin
Published: April 2021

Consider a contemporary retrieval of Aristotle’s account of moral perception. Drawing from EN.VI.8, Martha Nussbaum argues that we perceive moral particulars prior to ethical principles. First, I explain her priority of the particular thesis. The virtuous person perceives value in the world, as part of her moral deliberation. This perceptual skill is an important aspect of her virtuous activity, and hence also part of her eudaimonia. Second, I present her priority thesis with a dilemma: our perception of moral particulars is either non-inferential or it is inferential. If Nussbaum accepts a non-inferential interpretation, then she is committed to an unsavory view about moral epistemology –one that invites intuitionism and relativism. But if she accepts a non-inferential account, then the moral particular is no longer prior to the ethical principle. I suggest that her better option is to grab the second horn. This move avoids the problems of the first horn without sacrificing her neo-Aristotelian commitments or her overarching view that the perception of moral particulars is ineliminable to moral deliberation (and eudaimonia). At the same time, this move renders her priority thesis trivial.
Nationalism, Globalism, and Religion
Authors: Farina John
Published: April 2021

Contemporary political debate is replete with presentations of nationalism that see it as a reactionary movement with a troubling history and dubious prospect. It is often contrasted with globalism, presented in equally sweeping terms. A closer look at the tensions between nationalism and globalism reveals a far more complex picture, especially when the nineteenth and twentieth century histories of those terms are examined. This paper argues for a more nuanced view of nationalism and its value in societies, a value that depends on the action of metapolitical forces, most especially religion, to save nationalism from violent distortions and globalism from naïve utopianism.
Los héroes de la pandemia: la construcción discursiva del colectivo de los trabajadores sanitarios durante la crisis del COVID-19
Authors: Moreno-Barreneche Sebastián
Published: April 2021

Besides its impact in health, economics, and politics, the COVID-19 pandemic has allowed the emergence of phenomena of discursive nature, specifically regarding the solutions societies have found to make sense of the crisis caused by the uncontrolled spread of the virus. From a socio-semiotic approach, this article analyzes the collective identity construction process of the healthcare workers during the pandemic. After generally introducing semiotics as the discipline interested in meaning-making and signification, this paper studies four semiotic mechanisms that can be identified in the processes of discursive construction of collective identities. The aim is to explore how those have been developed during the pandemic in the specific case of healthcare workers. As it is shown, the case renders visible the semiotic mechanisms of segmentation, actorialization, generalization, and axiologization.
La ruptura de las uniones en Colombia y sus diferenciales. Una aproximación biográfica a partir de la Encuesta Nacional de Demografía y Salud de 2015
Authors: Ruiz-Vallejo Fernando
Published: April 2021

This study estimates the intensity and timing of the first union dissolution in Colombia and its regions, based on the application of survival analysis techniques with information from the 2015 Demographics and Health Survey (n = 24,823). The results demonstrate that after 20 years, 48% of unions were dissolved. The highest risk is associated with younger cohorts, common law marriage, early age at union, and age gaps where the woman is similar in age or older than her partner. Similarly, a higher level of education, as well as living in urban areas or certain regions, increases the risk of union dissolution. On the contrary, having preschool children was identified as a characteristic reducing this risk.
Örgütsel Ekoloji Kuramına Güncel Bir Bakış: Kamu İktisadi Teşekküllerinin Küresel Pazarlardaki Rolü
Authors: COŞAR Bora
Published: April 2021

Bu makalede Hannan ve Freeman tarafından ortaya konan ve bulunduğu dönemin önemli bir boşluğunu dolduran örgütsel ekoloji kuramının ve yaklaşımlarının, günümüzün küresel pazarlarında geçerliliği olmadığı savunulmuş ve buna bağlı olarak güncel bir bakış açısı getirilmeye çalışılmıştır. Bu bağlamda günümüzün büyük güçleri olarak bilinen kamu iktisadi teşekkülleri incelenmiş ve onların pazarlardaki baskın konumu göz önünde bulundurulmuştur. Bu örgütlerin hem pazardaki diğer firmalara rakip olması hem de devlet olarak kanun koyucu şeklinde yer almasıyla, örgütsel ekolojinin doğal seçilim sürecinin anlamını yitirdiği ve bu durumun bu örgütlerin seçiciliği altında yapay seçilim süreci olarak pazarları şekillendirdiği savunulmaktadır. Bu bağlamda kuramın diğer yaklaşımları da eleştirilmiş ve konuyla ilgili yeni yaklaşımlar önerilmiştir.
Türkiye’nin Demiryolu Yük Taşımacılığı Talebinin Zaman Serisi Analizi ile Tahmini
Authors: KARADAĞ ALBAYRAK Özlem
Published: April 2021

Taşıma modları içinde yatırım maliyeti yüksek olmasına rağmen kütlesel taşımada navlun
maliyeti oldukça düşük olan mod demiryolu taşımacılığıdır. Demiryolunda taşınacak yük miktarının
tahmin edilmesi etkin planlama yapılmasını sağlar. Bu çalışma Türkiye’de demiryolu yük
taşımacılığına oluşacak talep modeli 1978-2018 arasındaki yıllık zaman serisi verilerini kullanarak
analiz edilmiştir. Johansen eşbütünleşme analizi ve varyans hata düzeltme modeli ile tahminin
belirleyicilerinin kısa ve uzun dönem esneklikleri tahmin edilmiştir. Elde edilen sonuçlara göre
demiryolu yük talebinin en önemli belirleyicisi navlun oranı olmuştur. Demiryolu yük talebinin
navlun oranına göre uzun dönem ve kısa dönem esneklikleri - 0,181 ve -0,184 ile çok yakındır.
Demiryolu yükü talebinin uzun dönemli dış ticaret hacmi esnekliği anlamlı ve pozitiftir, yani ticaret
hacmi arttıkça demiryoluna oluşacak yük talebi artacaktır. Fakat demiryolu yükü talebinin uzun
dönemli Gayrisafi Katma Değer ve Yakıt Fiyatı esneklikleri anlamlı ve negatiftir. Yani bu
değişkenlerdeki artık demiryolu yük talebini azaltacaktır. Hata düzeltme modeline göre demiryolu
yük talebindeki herhangi bir son dönem sapmasının 55%’i bir yıl içinde düzeltilmekte ve uzun dönem
denge ilişkisi eski haline gelebilmektedir.

Cognizance of stem cells: A gist
Authors: Silvia C R Wilma Delphine , Sen Debalina , Kumar Pinnelli Venkata Bharat , A Priyanka
Published: April 2021

Stem cells are undifferentiated cells which usually arises from one cell (clonal) and has the characteristic of self renewal i.e ability to proliferate and differentiate into various styles of cells (potent). Depending upon the potencies there are different sources of stem cells. Pluripotent cells have the flexibility to differentiate into tissues from the three germ layers. There are various sources of stem cells with varying potencies. Pluripotent cells have the ability to differentiate into tissue from all 3 germ layers (endoderm, mesoderm, and ectoderm). Multipotent stem cells may differentiate into tissue derived from a single germ layer like mesenchymal stem cells which form adipose tissue, bone, and cartilage thanks to the limited generation of most somatic cells, stem cells’ capacity to replenish damaged somatic cells and maintain a self-renewing reservoir of progenitors is crucial for homeostasis in many tissues of the many organisms. Thus, there is an immense interest in understanding the mechanisms for self-renewal and differentiation in stem cells, given their potential applications in regenerative medicine and studies of human development or aging. This review article emphasizes on stem cells and its various types.

Published: April 2021

Type 2 diabetes is the chronic metabolic disease associated with cardiovascular, renal and neurological complications, responsible for morbidity and mortality. In addition, the incidence of cardiovascular disease was 10.3 out of 1000 type 2 diabetics per year in low-income countries like Gabon. Thus, this work was setup to determine the cardiometabolic profile of type 2 diabetic subjects in Libreville.

This was a cross-sectional analytical study, which took place at the Endocrinology Department of the University Hospital Center of Libreville (CHUL) and at the Biochemistry Laboratory of Health Sciences University (USS). 210 subjects were enrolled, including 95 diabetics and 115 controls. Their anthropometric values were recorded and biochemical parameters obtained by spectrophotometric methods. Metabolic syndrome was defined according to NCEP ATP III criteria, and 10-years cardiovascular risk was assessed using Framingham and American Heart Association (AHA) / ACC risk scores.

The metabolic syndrome was found among 75.8% of diabetics against 24.2% among controls (p = 0.000). In all, 42.1% of diabetics had a high cardiovascular risk by the Framingham equation versus 6.1% for the controls and 41.1% with the AHA / ACC score versus 4.3% for the controls. Diabetic women were more affected than men (54.6% against 13.8% p = 0.000).

Type 2 diabetics should undergo intensive management of cardiovascular risk factors in order to reduce the level of cardiovascular risk. Thus their life shall be improved by reducing morbidity and mortality.
Urinary transferrin as early marker of renal damage in type II diabetes mellitus: A case–control study
Authors: A Pavana , K C Vasudha , Kalra Pramila
Published: April 2021

Microalbuminuria is a reversible stage of renal dysfunction and its detection allows early intervention and treatment of diabetic nephropathy. Therefore, a more reliable biomarker is required to diagnose early, reversible stage of renal dysfunction.

To evaluate the utility of urinary transferrin (UTRANS) as an early predictive marker in type II diabetes mellitus (T2DM).

This cross-sectional study included 40 normoalbuminuric and 20 microalbuminuric T2DM patients and 20 clinically healthy controls.

Materials and methods: All baseline characteristics such as glucose (fasting and postprandial), serum creatinine, HbA1c, urinary albumin, creatinine, and UTRANS were estimated.

SPSS software version 20, R studio 3.6.2. Shapiro test, Chi-square test, Analysis of variance, Kruskal Wallis, and receiver operating characteristic (ROC).

Urinary albumin-to-creatinine ratio and UTRANS showed a significant difference among normoalbuminuric and microalbuminuric T2DM patients compared to controls (P = 0.000). UTRANS and TRANS/creatinine ratio positively correlated in normoalbuminuric, macroalbuminuric and control groups (P < 0.05). UTRANS was an excellent to outstanding discriminator (Area under the curve: 0.8 – >0.9), indicating UTRANS was able to differentiate between healthy controls, normoalbuminuric, and microalbuminuric T2DM subjects.

UTRANS may act as a potential biomarker that can be used as an early screening marker for renal injury, even before progression to the stage of microalbuminuria.
Effect of haemodialysis on renal profile in chronic renal failure patients at a tertiary care centre
Authors: Singh Ram Ranjan , Shekhar Sudhanshu , Sinha Rakesh , Tripathy Sunita
Published: April 2021

: In chronic renal failure there is a steady and continued decrease in renal clearance or glomerular filtration rate (GFR), which leads to the gathering of urea, creatinine and other waste metabolites in the blood. Haemodialysis is considered as a good therapeutic option in the context of the renal replacement therapies in which different body waste products including urea, creatinine and free water are removed from the blood. In view of that, the present study was conducted to evaluate the effect of haemodialysis on different renal biochemical parameter in CRF patients.

The present study was a hospital based study including 84 chronic renal failure patients on haemodialysis attending a tertiary care hospital in Bihar. Blood samples were collected before and four hours after haemodialysis and serum urea, creatinine, uric acid, potassium, sodium and calcium were estimated.

Our results revealed that there was significant decrease in the serum level of urea, creatinine, uric acid and potassium in post dialysis samples with p-value (<0.001, 0.001 0.003 and 0.001) respectively when compared to pre dialysis samples, while showed significant increase of sodium and calcium level in post dialysis samples with p-value (<0.004 and 0.005)

The Study concludes that, haemodialysis increase serum sodium and calcium level and decrease serum urea, creatinine, uric acid and potassium level.

Breast cancer is a leading cause of death in women due to cancer. According to WHO in 2018, it is estimated that 627.000 women died from breast cancer, that is approximately 15 % of all cancer deaths among women [3]. Early detection is a very important factor to reduce mortality by 25-30 %. Mammography is the most commonly used technique in detecting breast cancer using a low-dose X-ray system in the examination of breast tissue that can reduce false positives. A Computer-Aided Detection (CAD) system has been developed to effectively assist radiologists in detecting masses on mammograms that indicate the presence of breast tumors. The type of abnormality in mammogram images can be seen from the presence of microcalcifications and the presence of mass lesions. In this research, a new approach was developed to improve the performance of CAD System for classifying benign and malignant tumors. Areas suspected of being masses (RoI) in mammogram images were detected using an adaptive thresholding method and mathematical morphological operations. Wavelet decomposition is performed on the Region of Interest (RoI) and the feature extraction process is performed using a GLCM method with 4 statistical features, namely, contrast, correlation, entropy, and homogeneity. Classification of benign and malignant tumors using the MIAS database provided an accuracy of 95.83 % with a sensitivity of 95.23 % and a specificity of 96.49 %. A comparison with other methods illustrates that the proposed method provides better performance.

This article discusses an idea of a joint analysis of medical images and texts aimed at improving the quality of automated diagnosis of emphysema. We compare the quality of image classification with and without taking into account the localization of the pathology mentioned in radiological reports. The study was carried out on sets of real images of computed tomography of the lungs obtained in clinical studies at Samara State Medical University. It was established that the use of information on the localization of pathology contained in radiological reports leads to an increase in the F-score for the detection from 0.55 to 0.73.

By numerically simulating the sharp focusing of fractional-order vector beams (0≤m≤1, with azimuthal polarization at m=1 and linear polarization at m=0), it is shown that the shape of the intensity distribution in the focal spot changes from elliptical (m=0) to round (m=0.5) and ends up being annular (m=1). Meanwhile, the distribution pattern of the longitudinal component of the Poynting vector (energy flux) in the focal spot changes in a different way: from circular (m=0) to elliptical (m=0.5) and ends up being annular (m=1). The size of the focal spot at full width at half maximum of intensity for a first-order azimuthally polarized optical vortex (m=1) and numerical aperture NA=0.95 is found to be 0.46 of the incident wavelength, whereas the diameter of the on-axis energy flux for linearly polarized light (m=0) is 0.45 of the wavelength. Therefore, the answers to the questions: when the focal spot is round and when elliptical, or when the focal spot is minimal -- when focusing an azimuthally polarized vortex beam or a linearly polarized non-vortex beam, depend on whether we are considering the intensity at the focus or the energy flow. In another run of numerical simulation, we investigate the effect of the deviation of the beam order from m=2 (when an energy backflow is observed at the focal spot center). The reverse energy flow is shown to occur at the focal spot center until the beam order gets equal to m=1.55.

Purpose of the study: to determine the regional characteristics of the health indicators of pregnant women on the basis of integral assessment of extragenital pathology, complications and adverse consequences of pregnancy. Materials and methods. A comprehensive retrospective analysis of regional characteristics and dynamics of the main indicators of pregnant women’s health in Ukraine for the period 2010–2019 was carried out. According to the Center for Medical Statistics of Ukraine integral assessment (IA) of pregnant women’s health was carried out according to the generally accepted calculation method using integral indicators of the extragenital pathology frequency, pregnancy complications and its adverse consequences.Results. Health of pregnant women remains unsatisfactory with multidirectional trends in the frequency of individual pathologies in recent years. Simultaneously with a downward trend against the background of a high level of anemia and genitourinary system diseases (24.73 and 14.38 per 100 pregnant women in 2019, the rate of decline was 6.29% and 1.74%), gestosis, preeclampsia and eclampsia (6.57, 2.11 and 1.2%, 9.48%), not carrying a pregnancy, delivering a dead fetus (5.84, 0.43 and 15.92%, 9.3%), the incidence of circulatory system diseases and thyroid gland dysfunctions (7.61, 9.88, growth rate 18.7%, 2.33%) is increasing. Incidence of diabetes in pregnant women in Ukraine rapid increases in 10.4 times (0.17 per 100 pregnant women in 2010 and 0.77 in 2019). High regional differences in the frequency of different pathologies of pregnant women were revealed. The difference between the highest and lowest rates of circulatory system diseases in 2019 was 23.9 times, diabetes mellitus – 12.6 times, thyroid diseases – 5.4 times, genitourinary system diseases – 4.3 times, anemia in pregnant women – 3.4 times, and complications and adverse effects of pregnancy – 2.4–4.7 times. The analysis of the IA of the health status of pregnant women according in 2019 revealed that the level of health was higher than the average in Ukraine in Ivano-Frankivsk (65.5%), Zaporizhzhya (72.82%), Odesa (75.5%), Zakarpattia (76.5%), Lviv (81.1%), Sumy (81.3%), Luhansk (84.3%) and Ternopil (84.4%) regions, and low than the average level in Dnipropetrovsk (132.35%), Poltava (123.1%), Chernivtsi (118.0%), Chernihiv (111.7%) regions and Kyiv (117.1%). Conclusions. Developed toolkit for the IA of pregnant women’s health makes it possible to provide an objective assessment of pregnant women’s health in general and for individual components in the context of regions as a means of timely identification of problems that require intervention and effective management decisions to minimize risk factors that cause impaired health in pregnant women.

Research aim was to identify differences in anthropometric, somatotypological and components of body weight between the respective groups of healthy teenager girls and patients with primary dysmenorrhea. Identifying such relationships will identify risk groups for primary dysmenorrhea and prevent its occurrence in adolescent girls.Materials and methods. All materials presented in the article are part of the dissertation “Prognosis, diagnosis and prevention of primary dysmenorrhea in patients of pubertal age with different somatotypes.” Authors analyzed the indicators of 270 teenager girls, among which 200 persons were almost healthy and 70 patients with primary dysmenorrhea. For examination were used questionnaire-anamnestic method, measurement of anthropometric, somatotypological, components of body weight, ultrasound examination of the pelvic organs in two cycle phases and hormonal profile examination in the follicular and luteal phase of the menstrual cycle and statistical research methods. Results. Comparing anthropometric, somatotypological and components of body weight between the relevant (general or somatotype) groups of healthy girls and patients with primary dysmenorrhea, between the general group with primary dysmenorrhea and girls with primary dysmenorrhea of different somatotypes, as well as between patients with primary dysmenorrhea different somatotypes found significant differences (p <0.05) or tendencies of differences (p = 0.05) among total body size, body circumference, torso diameter, width of the distal epiphyses of the long tubular bones of the extremities, thickness of skin and fat folds, somatotype components, indicators of body weight composition.Conclusions. Medicine of the future will be preventive, aimed to identify predictors of pathology, factors influencing the development of nosology, and individual characteristics of teenage girls, which may lead to etiological and pathogenic impulse of clinical progression of primary dysmenorrhea. Therefore, the identification of prognostic markers of primary dysmenorrhea and formation of risk groups can improve not only life quality of a particular girl, but also the reproductive potential of nation.

Research aim: to determine the clinical efficacy and safety of bioavailable curcumin Longimin® in the complex anti-relapse therapy of patients with extragenital endometriosis after surgery.Materials and methods. Study involved 45 women with a mean age of 29.3 ± 3.6 years with a diagnosis of extragenital endometriosis. After surgical treatment of this disease all patients were prescribed dienogest 2 mg/day for 6 months with anti-relapse purpose. After that, 22 patients did not receive drug treatment (group 1) and other 23 women started a six-month course of 400 mg bioavailable curcumin (group 2).Results. After 12 months of observation 3 cases (13.6%) of newly formed foci of endometriosis were found among patients of group 1, two of which were multi-endometriomas, and the third was retrocervical heterotopia. There were no signs of recurrence in the group of sequential use of dienogest and bioavailable curcumin. In addition, 6 months after completion of hormonal treatment the number of women with chronic pelvic pain in group 1 was increased and average score on a visual analogue scale (VAS) was increased by 80% (p ≤0.05). It was accompanied by a stable moderately high level of anxiety throughout the observation period. At the same time the number of women who complained of intermenstrual pain in group 2 decreased from 15 to 13, and the average VAS score decreased by 13% (p ≥0.05) during the treatment period. Patients in group 2 noted an improvement in emotional control during treatment, which resulted in the average score decrease on the scale of personal and situational anxiety of the Spielberg-Hanin's questionnaire (25% and 30% respectively, p ≤0.05).Conclusions. The nature of the endometriosis development and progression is multipathogenetic. Blocking only its hormonal link, especially in cases of extragenital forms, may not be sufficient to stop the pathological process and prevent recurrence in the long term. Оbtained results of sequential course of dienogest and bioavailable curcumin Longimin® with anti-relapse purpose showed the wider clinical effectiveness of this therapy, which is probably based on additional inhibition of systemic inflammation, proliferation, stroma and psychogenic component of disease.
