Crise da Água em São Paulo na Perspectiva dos Órgãos Governamentais: Crise Hídrica ou de Informação?
Authors: Mazzarino Jane Marcia , Turatti Luciana
Published: March 2020

A internet possibilita às organizações sociais o papel de protagonistas na consecução do direito à informação, de modo a estimular a participação cidadã no debate público sobre as mais diversas questões, dentre as quais a hídrica. Este estudo analisa notícias veiculadas por duas organizações governamentais responsáveis pela gestão das águas no contexto brasileiro: uma nacional e outra do estado de São Paulo. Discute-se se suas práticas comunicativas atendem aos pressupostos legais do direito à informação no processo de agendamento e enquadramento da crise hídrica de São Paulo. O estudo é descritivo e analítico, qualitativo, de base bibliográfica e documental. A amostra é não probabilística, por tipicidade e acessibilidade. Emergiram quatro categorias de análise a partir de uma diversidade de elementos que compuseram a macrocategoria enquadramento: fontes, conflitos, responsabilidade e soluções. Concluiu-se que a organização estadual enquadra a crise como uma situação “sob controle”, enquanto a organização nacional busca explicar tecnicamente os mecanismos para o seu enfrentamento. De modo geral, e considerando-se a relevância do problema, as duas organizações publicaram pouco e informaram predominantemente a partir de interesses institucionais e não do interesse público. Por fim, verifica-se que o papel das organizações de caráter ambiental deve ser ampliado em se tratando da implementação do direito à informação ambiental.

O cerrado sensu stricto é uma fitofisionomia savânica com grande diversidade florística e que ocupa, aproximadamente, 70% do bioma Cerrado, porém, sofre uma rápida conversão para áreas de uso antrópico. Diante disso, objetivou-se analisar a estrutura fitossociológica de um cerrado sensu stricto em Gurupi, Tocantins. Em cinco parcelas de 20x50m foram amostrados os indivíduos com circunferência a altura do peito ≥ 10 cm. Foram encontrados 906 indivíduos, distribuídos em 102 espécies, 42 famílias e 78 gêneros. O índice de diversidade (H’) foi de 3,70 e a equabilidade (J’) de 0,80. A família com o maior índice de valor de importância (IVI) foi Myrtaceae. A espécieMyrcia fallax obteve o maior número de indivíduos e de IVI (23,1%). Na dominância relativa se destacaram Protium heptaphyllum (12,2%) e Tapirira guianensis (7,1%). As demais espécies encontradas apresentaram valores inferiores à (5,7%). Os índices obtidos neste estudo indicam a existência de uma alta diversidade florística.

The determination of infection rate parameter from in vitro macrophages infected by Leishmania amastigotes is fundamental in the study of vaccine candidates and new drugs for the treatment of leishmaniasis. The conventional method that consists in the amastigotes count inside macrophages, normally is done by a trained microscope technician, which is liable to misinterpretation and sampling. The objective of this work is to develop a method for the segmentation of images to enable the automatic calculation of the infection rate by amastigotes. Segmentation is based on mathematical morphology in the context of a computer vision system. The results obtained by computer vision system presents a 95% accuracy in comparison to the conventional method. Therefore, the proposed method can contribute to the speed and accuracy of analysis of infection rate, minimizing errors from the traditional methods, especially in situations where exhaustive repetitions of the procedure are required from the technician.

Published: March 2020

Fecal enterococci are generally not virulent; however, multidrug-resistant strains have emerged as leading causes of hospital-acquired infections. Thus, periodic enterococci monitoring should be included in highly populated cities to control the dissemination of multidrug-resistant strains to the marine environment. This study aimed to quantify enterococci bacteria from water and intertidal sediment samples in a beach located near Rio de Janeiro touristic spots. We also intended to accomplish if enterococci should be included in touristic beaches sanitary monitoring. Toward this approach, we monitored from August to December 2014 fecal indicator bacteria (FIB) at a beach close to some touristic spots through multiple tube method. Although FIB quantification was within sanitary standards of Brazilian legislation, high enterococci densities (=30 MNP.100 mL-1) were detected in the water collected in August. Thus, enterococci monitoring should be included in touristic beaches to avoid the risk of multidrug-resistant bacteria dissemination among swimmers and beachgoers.

Medicinal plants produce secondary metabolites with special biological activities, which may be used
as new therapeutic alternatives. For instance, tea tree essential oil (TTO) was shown to exert antimicrobial, antifungal,
anthelmintic, antiviral, anti-tumor and anti-inflammatory activities. Due to their thermal instability, active
principles can be easily degraded by physicochemical processes; therefore, they must be protected to increase
their time of action and improve their controlled release. The aim of this review is to discuss formulations incorporating
encapsulated TTO as the active ingredient. Micro and nanoencapsulated systems proved to be more
thermostable than TTO and to exert better antimicrobial, antifungal, antiparasitic and larvicidal effects. Nanoencapsulation
also reduced oil toxicity. Emulsified and hybrid systems developed by various methods showed improved
repellent, antibacterial, antifungal and anti-inflammatory activities, thereby proving promising for the
pharmaceutical industry. Liposomal formulations produced by hydration of lipid films exhibited constant rate of
terpinen-4-ol release. In addition, their incorporation into biomaterials, such as sponges, nanofibers and films,
showed great potential for treating infections. Mainly due to the advantages of their incorporation into new drug
delivery systems over conventional formulations, there is an interest in the development of systems containing
TTO as a pharmaceutical ingredient of plant origin.

Authors: De la Corte-Rodriguez Hortensia , Rodriguez-Merchan E. Carlos , Alvarez-Roman M. Teresa , Martin-Salces Monica , Jimenez-Yuste Victor
Published: March 2020

Background:

It is important to discard those practices that do not add value. As a result,
several initiatives have emerged. All of them try to improve patient safety and the use of health
resources.

Purpose:

To present a compendium of "do not do recommendations" in the context of hemophilia.

Methods:

A review of the literature and current clinical guidelines has been made, based on the best
evidence available to date.

Results:

The following 13 recommendations stand out: 1) Do not delay the administration of factor
after trauma; 2) do not use fresh frozen plasma or cryoprecipitate; 3) do not use desmopressin in
case of hematuria; 4) do not change the product in the first 50 prophylaxis exposures; 5) do not
interrupt immunotolerance; 6) do not administer aspirin or NSAIDs; 7) do not administer intramuscular
injections; 8) do not do routine radiographs of the joint in case of acute hemarthrosis; 9) Do
not apply closed casts for fractures; 10) do not discourage the performance of physical activities;
11) do not deny surgery to a patient with an inhibitor; 12) do not perform instrumental deliveries in
fetuses with hemophilia; 13) do not use factor IX (FIX) in patients with hemophilia B with inhibitor
and a history of anaphylaxis after administration of FIX.

Conclusions:

The information mentioned previously can be useful in the management of hemophilia,
from different levels of care. As far as we know, this is the first initiative of this type regarding
hemophilia.

Adopting Patient Portals in Hospitals: Qualitative Study
Authors: Hulter Pauline , Pluut Bettine , Leenen-Brinkhuis Christine , de Mul Marleen , Ahaus Kees , Weggelaar-Jansen Anne Marie
Published: March 2020

Background

Theoretical models help to explain or predict the adoption of electronic health (eHealth) technology and illustrate the complexity of the adoption process. These models provide insights into general factors that influence the use of eHealth technology. However, they do not give hospitals much actionable knowledge on how to facilitate the adoption process.

Objective

Our study aims to provide insights into patient portal adoption processes among patients and hospital staff, including health care professionals (HCPs), managers, and administrative clerks. Studying the experiences and views of stakeholders answers the following question: How can hospitals encourage patients and HCPs to adopt a patient portal?

Methods

We conducted 22 semistructured individual and group interviews (n=69) in 12 hospitals and four focus groups with members of national and seminational organizations and patient portal suppliers (n=53).

Results

The effort hospitals put into adopting patient portals can be split into three themes. First, inform patients and HCPs about the portal. This communication strategy has four objectives: users should (1) know about the portal, (2) know how the portal works, (3) know that action on the portal is required, and (4) know where to find help with the portal. Second, embed the patient portal in the daily routine of HCPs and management. This involves three forms of support: (1) hospital policy, (2) management by monitoring the numbers, and (3) a structured implementation strategy that includes all staff of one department. Third, try to adjust the portal to meet patients’ needs to optimize user-friendliness in two ways: (1) use patients’ feedback and (2) focus on optimizing for patients with special needs (eg, low literacy and low digital skills).

Conclusions

Asking stakeholders what they have learned from their efforts to stimulate patient portal use in hospitals elicited rich insights into the adoption process. These insights are missing in the theoretical models. Therefore, our findings help to translate the relatively abstract factors one finds in theoretical models to the everyday pragmatics of eHealth projects in hospitals.

Authors: Field Michael E , Goldstein Laura , Yu Lee Stephanie Hsiao , Kalsekar Iftekhar , Coplan Paul , Wong Charlene , Khanna Rahul , Gold Michael R , Reynolds Matthew R , Winterfield Jeffrey R
Published: March 2020

Aim:
To compare outcomes among patients with implantable cardioverter defibrillator/cardiac resynchronization therapy-defibrillator undergoing outpatient ventricular tachycardia (VT) catheter ablation using intracardiac echocardiography (ICE) versus no ICE.
Patients & methods:
Patients were classified into ICE (n = 1143)/non-ICE (n = 1677) groups based on ICE procedure codes. Patients in each group were propensity matched on study covariates. Survival analyses were used to assess outcomes. To examine residual confounding, falsification outcomes were evaluated.
Results:
ICE patients had a 24% lower risk of all-cause readmissions, 24% lower risk of cardiovascular-related and 20% lower risk of VT-related readmissions compared with non-ICE patients. Falsification analyses for ICE use association were nonsignificant.
Conclusion:
Patients with implantable cardioverter defibrillator/cardiac resynchronization therapy-defibrillator undergoing VT ablation with ICE use had significantly lower likelihood of VT-related readmission.
La variación en maya yucateco: un estudio descriptivo desde la dialectología perceptual
Authors: Hernández Méndez Edith
Published: March 2020

Desde la perspectiva de la dialectología perceptiva y mediante un estudio exploratorio y descriptivo, nos propusimos examinar la habilidad de quince bilingües de maya-español para identificar posibles variedades de lengua maya y relacionarlas con una región geográfica, determinar los rasgos más salientes que usan para distinguir una variedad de otra e identificar algunos factores que pueden afectar esta percepción dialectal. Algunas tareas de la metodología usada por Preston (1999), Mase (1999) y Clopper y Pisoni (2004) fueron adaptadas en el presente estudio, como la tarea de categorización controlada con mapa y la tarea de iguales o diferentes. Los resultados muestran que la habilidad de categorización de variedades entre los participantes fue pobre o deficiente, afectada principalmente por la escasa exposición y experiencia con mayahablantes de otras comunidades. Los límites geográficos, la distinción entre habla urbana / rural y entre la jach maya (la maya pura, antigua, verdadera) y el xe’ek’ (la maya mezclada) también se identificaron como una guía de reconocimiento de variedades o zonas dialectales. Los elementos suprasegmentales (entonación, melodía, ritmo, velocidad de la elocución) y el léxico, en general, resultaron los elementos lingüísticos salientes que guiaron la percepción dialectal de los participantes.

Published: March 2020

Рассматриваются проблемы оценки качества строительных работ. Выявлены основные дефекты стен: отклонение стены от вертикали, выпуклости и вогнутости, отклонения углов сопряжения стен от значения в 90 градусов, конусность дверных и оконных проемов.Представлен алгоритм функционирования системы технического зрения, позволяющей восстановить трехмерные координаты стен за счет анализа деформации структурированной сетки, проецируемой на них. Ключевыми объектами, по которым производится восстановление геометрии, являются пересечения горизонтальных и вертикальных линий контрастной сетки. Полученные координаты ключевых точек сравниваются с координатами ключевых точек в идеальном случае, т. е. при проекции на абсолютно ровную вертикальную плоскость.Представлена формула расчета отклонения от вертикали для каждой ключевой точки. Для точной классификации дефектов и определения их количественных характеристик, а также расчета объема материалов для их устранения предложен метод аппроксимации полученных дискретных значений аналитически заданной поверхностью. Рассмотрены наиболее применимые виды поверхностей второго порядка.В рамках исследования на основе разработанного алгоритма планируется создание функционального программного обеспечения с удобным пользовательским интерфейсом и оценка разработанной системы на практике.
Measuring of Amplitudes, Frequencies and Phases of Simple Periodic Components of the Complex Signal at Spectral Analysis by Fast Fourier Transform
Authors: Lеn’kоv S. V.
Published: March 2020

Предложен способ оценки амплитуд, частот и фаз конечного числа простых периодических составляющих сложного сигнала по дискретному спектру сложного сигнала, полученному быстрым преобразованием Фурье. В предложенных алгоритмах используются априорные данные (объем реализации и шаг дискретизации) и измеренные или вычисленные данные (действительные и мнимые части отсчетов спектра, лежащих около наибольших максимумов модуля спектра).Проведено моделирование работы предложенного алгоритма. Моделировался суммарный сигнал, состоящий из семи синусоид с единичными амплитудами, разными частотами и фазами. Шум канала моделировался добавлением нормально распределенной случайной величины к точному отсчету суммарного сигнала, а помеха 50 Гц – добавлением реализации синусоиды со случайной амплитудой и фазой. Определение параметров слагаемых синусоид осуществлялось двумя итерационными способами. При первом способе суммарный спектр сигнала рассматривался как сумма спектров семи независимых сигналов; при втором способе – как сумма  спектров независимых пар сигналов. Погрешности определения фаз не превосходили 3 %, а погрешности измерения амплитуд и частот – 1 %.Проведенное исследование может служить теоретическим обоснованием алгоритма измерения амплитуд, частот и фаз конечного числа простых периодических составляющих сложного сигнала с помощью быстрого преобразования Фурье при отсутствии априорных сведений о параметрах сигнала с использованием только действительных и мнимых составляющих дискретного спектра сигнала.
Low-Fee Private Schools: Case Studies from Ghana
Authors: Brion Corinne
Published: March 2020

Low-Fee Private Schools (LFPSs) have been controversial globally. This paper examines Christian Low-Fee Private Schools in the Greater Accra region of Ghana. This qualitative study uses four schools as cases. Specifically, the researchers examine how these schools come into existence, who they serve and why parents choose to send their children to these schools. Findings reveal that the school proprietors do not operate schools to make profits and that parents choose Christian LFPSs for spiritual, financial, quality, and proximity reasons. The study demonstrates that these Christian LFPSs provide families with an alternative choice that fits their beliefs, values and perceptions.
Effect of heightened interoceptive awareness among smokers on misinterpretation of emotional arousal
Authors: Kim Minseung , Park Yeon-Ju , Kim Kiho , Lee Jang-Han
Published: March 2020

We investigated the differences in the emotional experiences of people who smoke and have damaged interoceptive awareness. Interoception is the sensation of the physiological condition of the body, and it has 2 biases: neglect and amplification of bodily feedback. We recruited 72 participants
and divided them into 4 groups according to smoking status and interoceptive bias based on their scores on the Multidimensional Assessment of Interoceptive Awareness. All groups assessed their physiological and subjective arousal before and after watching video clips (positive–low arousal,
positive–high arousal, negative–low arousal, negative–high arousal, neutral). The results indicated that people with amplification (vs. neglect) bias who smoked showed stronger subjective arousal to neutral stimuli. In contrast, people with amplification (vs. neglect) bias
who did not smoke showed stronger subjective arousal to positive stimuli. These findings suggest that people who smoke and have an amplification bias could be more likely to misinterpret neutral emotional stimuli, leading to an increased craving for smoking.
Change in the level of depression among Chinese college students from 2000 to 2017: A cross-temporal meta-analysis
Authors: Feng Bing , Zhang Yan , Zhang Lei , Xie Xiaodan , Geng Wenxiu
Published: March 2020

University enrollment in China was expanded in 1999, with positive results. However, several psychological indicators of Chinese college students, such as increased anxiety across generational cohorts, have been revealed. To examine generational cohort changes in Chinese college students'
depression levels from 2000 to 2017, we conducted a cross-temporal meta-analysis involving 93 studies (117 data points, N = 87,503). The results showed that, according to responses to the SelfRating Depression Scale, the depression level of Chinese college students increased by 6.04
points (SD increase = 0.66). In addition, male (vs. female) college students demonstrated increased depression. Theoretical and practical implications are discussed.
Color preference and color meaning in the context of flags
Authors: Zhang Tengxiao , Shi Yunpeng
Published: March 2020

Researchers have argued that people's general color preferences can readily be generalized to their color preferences for artificial objects. However, although a strong general preference for blue has been documented, recent researchers have reported a preference for red when viewed
on national flags. We addressed this inconsistency by examining the flag color preferences of 181 Chinese participants across 3 contexts: own nation, allied nation, and enemy nation. We found that general color preferences did not generalize to flag color preferences, and that preferences
varied across the different 3 flag contexts. Participants assessed competitive and affiliative meanings differently in terms of conformity to the most preferred flag colors across contexts, indicating that flags have different color meanings in different contexts. We have contributed to the
field of color psychology by demonstrating the effect of the interaction between color and context on people's color preferences.

Analysis of Character Presentation and Storyline in the Comic "Vulcaman-Z" aims to find out and identify visually how the presentation of characters and storylines in the comic Vulcaman-Z by Galang Tirtakusuma. This comic is a 4 point comic (yonkoma) or four panels, a slapstick action-comedy genre that is rarely found in the Indonesian comics industry. This comic also has several unique features such as the use of layouts, characters, colors, expressions, action lines, and word balloons. This research uses a descriptive qualitative method with interviews, literature study and observation data collection methods. The purpose of this research is the initial research conducted jointly with students to uncover several Indonesian comic artists' styles which later become a study of revealing comic styles from Indonesia. As we know that Indonesian comics are still very influential with foreign comics, both Japanese and American. The comic style possessed by Indonesia does not yet have own characteristics, although some comic artists have tried to express the identity of Indonesia through cultural ornaments and stories. But the presentation and style of comics are still using or the same as the style that is outside. Based on this, this research is present as an effort to discover the characteristics of Indonesia in Comics or to give an idea to Indonesian comic artists to present new style contributions to Comics.

Published: March 2020

Estudios enfocados en la fauna anura en la región de la Orinoquía Colombiana son escasos en comparación con otras regiones del país. Este trabajo evaluó la composición de la fauna anura en la cuenca baja del Río Bojabá en temporada de lluvias y sequía. Se realizaron dos salidas de campo, la primera en septiembre del 2013 correspondiente a temporada de lluvias y marzo del 2014 en época seca. Se demarcaron transectos de 100m x 2m de longitud y complementados con la búsqueda por encuentros visuales (VES) en tres formaciones vegetales previamente establecidas, con un esfuerzo de muestreo por sitio de 64 horas/observador para un total de 192 horas/observador en cada temporada y de 384 horas/observador en todo el estudio. Se registraron 231 ejemplares pertenecientes a cinco familias, diez géneros y 18 especies; la familia más representativa fue Hylidae con ocho especies, seguido de Leptodactylidae con seis. Los géneros más diversos fueron Scinax‚ Boana y Leptodactylus con tres especies cada uno. La especie dominante fue Dendropsophus mathiassoni con el 22,1% de la abundancia relativa, seguido de Engystomops pustulosus con el 15,6%; la especie rara fue Lithobates palmipes con el 0,4% de las abundancias. Los índices de diversidad alfa Shannon y Simpson mostraron resultados más altos para la temporada seca en comparación con la temporada de lluvias. Sin embargo, al índice de riqueza de Margalef fue mayor para los bosques de galería en ambos periodos con un valor de 2,7 estableciéndose como el hábitat más diverso taxonómicamente. Los humedales y las sabanas en temporada seca presentaron el grado más alto de similaridad, mientras que, los bosques de galería mostraron mayor disimilitud.

Efficient matrix-free direction method with line search for solving large-scale system of nonlinear equations
Authors: Halilu Abubakar , Waziri Mohammed , Yusuf Ibrahim
Published: March 2020

We proposed a matrix-free direction with an inexact line search technique to solve system of nonlinear equations by using double direction approach. In this article, we approximated the Jacobian matrix by appropriately constructed matrix-free method via acceleration parameter. The global convergence of our method is established under mild conditions. Numerical comparisons reported in this paper are based on a set of large-scale test problems and show that the proposed method is efficient for large-scale problems.
Gustaf Nyström ja Suomen puukirkkojen ainutlaatuisuus
Authors: Ripatti Anna
Published: March 2020

Artikkeli käsittelee Suomen puukirkkojen varhaista tutkimushistoriaa arkkitehti Gustaf Nyströmin (1856–1917) toiminnan kautta. Osoitan, että Nyström ymmärsi ensimmäisenä tutkijana Suomen puukirkkojen ja erityisesti tukipilarikirkkojen ainutlaatuisuuden. Hänelle vanhojen rakennusten dokumentointi ja suojelu ei ollut antikvaarista toimintaa, vaan arkkitehtuurin historian perinpohjainen tunteminen – kotimaan rakennusperintö mukaan lukien – oli välttämätön edellytys uuden, korkeatasoisen arkkitehtuurin syntymiselle. Suomen 1600- ja 1700 -lukujen puukirkot muodostivat hänen ajattelussaan omintakeisen ja kansainvälisesti merkittävän kokonaisuuden, jossa tekniikka ja taide yhdistyivät esimerkillisellä tavalla toisiinsa.

Fiksiranje tkiva važan je korak u histološkoj obradi tkiva za izradu trajnih mikroskopskih preparata. Svrha fiksacije je očuvanje stanica i međustaničnih struktura kako bi što više nalikovali živom materijalu. U ovom istraživanju analizirali smo morfološke značajke unutrašnjih organa potočne pastrve (Salmo trutta L.) fiksirani s dva različita fiksativa. 10% neutralni puferirani formaldehid (PNF) koji daje kvalitetne histološke uzorke, ali je toksičan i kancerogen te zamjenskog fiksativa FineFix-a (FF) smanjene toksičnosti baziranog na etanolu. Kako bi usporedili učinak dva istraživana fiksativa, tkiva su nakon fiksacije uklopljena u paraplast, izrezana i obojena rutinskomn histološkom hemalaun eozinskom (HE) tehnikomte histokemijskom metodom bojenja perjodne kiseline i Schiffovog reagensa te alcijanskog modrila. Uzorci tkiva probavnog, dišnog i cirkulacijskog sustava potočne pastrvepokazalisu da je PNF i dalje najbolji izbor pri standardnoj fiksaciji za histološke i histokemijske analize. Kao najveća razlika između dva upotrebljena fiksativa ističe se kvaliteta fiksacije vezivnog tkiva u proučavanim organima, koja je bolja u tkivima fiksiranim s PNF, u usporedbi s FF, dok se FF istaknuo kao bolji fiksativ u HE bojenju preparata probavnog sustava. Ukoliko će se i dalje upotrebljavati PNF, određena osjetljiva tkiva poput probavnih organa mogu zahtijevati modificiranje standardnih postupaka bojenja, a naročito HE metode, kako bi se osigurao bolji afinitet tkiva za boju, a time i bolje prepoznavanje morfoloških struktura u tkivu, dok se potraga za zamjenskim, jednako kvalitetnim, fiksativom bez formalina i dalje nastavlja.

Background: Patient satisfaction is the extent to which the patients feel that their needs and expectations are being met by the service provider. The survey of patient satisfaction with health care services is a growing concept in Nigeria, where study on this subject is just beginning to develop.

Objective: The aim of this study was to compare the patients’ satisfaction level with radiological services and to identify the factors that may account for the differences in their satisfaction between a public and a private health facility in Kano state Nigeria.
Method: The study was a cross-sectional prospective survey that targeted patients who visited radiology departments. Data was collected using a 43 item self-completion questionnaire designed in line with the objectives of the study. The data were categorized into groups and analysed using a statistical package for social sciences version 20.0, where descriptive statistics such as the percentages and frequencies were generated and tabulated. A chi-square test was used to test for the differences in the patients’ satisfactory level at (p<0.05).
Results: The results showed that 60.7% (n=85) were female while 39.3% (n=55) were male, 52.2% (n=47) of the respondents from the public hospital were dissatisfied, while 47.8% (n=43) were satisfied. At the private hospital, only 20% (n=10) were dissatisfied, while 80% (n=40) were satisfied with the radiological services received. The type of health facility and patients’ satisfaction was found to be statistically significant at (p<0.05).
Conclusion: The patients in the private health facility of the study were more satisfied than those at the public health facility because of prompt attention given to them immediately after arrival, immediate collection of their radiological reports, and high ergonometric environment provided by the hospital staff.
The Effect of Therapy of The Lower Urinary Tract Symptoms due to Prostatic Benign Enlargement on Erectile Function
Authors: Štraus Anja , Poteko Sandi , Starc Andrej
Published: March 2020

Background: Benign prostatic enlargement is the most common benign disease in men. The main cause for the emergence of benign prostatic enlargement is sexual hormone testosterone. Under the influence of enzyme 5-alpha reductase testosterone turns into active dihydrotestosterone, which is then combined with receptors and causes the growth of the prostate. Benign prostatic enlargement can cause the lower urinary tract symptoms. One of the treatment options of lower urinary tract symptoms due to benign prostatic enlargement is the treatment with medicaments – inhibitors 5-alpha reductase. Like any other medicament, this one can also have unpleasant side effects, between others reduced erectile function and reduced libido.

Methods: We used the International Index of Erectile Function (IIEF-5), Quality of Erection Questionnaire (QEQ), and demographic data.
Results: Men with benign prostatic enlargement have problems with keeping an erection even before starting the therapy with medicaments. After the therapy with inhibitors 5-alpha reductase the results of the research show that on the erectile function scale, there are no significant differences between the first and second measurement, but on the erectile dysfunction scale expected differences occur – the functionality decreases. We also noticed that the independent variables of age and employment status have influence on the result of medicament treatment in the way that older participants in the study have more issues with erectile function than younger ones. Secondly, the men in retirement have more problem than employed men. There were no noticeable connections between the level of completed education and the profession of the participants.
Conclusions: The results of the research were expected, according to the previously consulted literature, where the side effects of treatment with medicaments inhibitors 5-alpha reductase were already mentioned. The effects that the treatment has on erectile function are that the function deteriorates, that is why it is important that we seek doctor assistance immediately after it occurs. The disease mainly manifests itself in older generation of men and it has a negative effect on erectile function already at the very beginning. Before starting the treatment the patients would need to be informed about the side effects of the medicament treatment and they should be presented other possibilities of treatment without side effects for erectile function.

Introduction. Xenogeneic tissues decellularization represents the obtaining process of extracellular matrix derived scaffolds. Most antigens being cell based, non-immunogenicity is obtained by cells removal. Scaffolds are temporary structures with biologic and mechanical role. Scaffolds, stem cells and bioreactors represent premise of regenerative medicine, aiming towards the ideal valvular substitute. In previous studies, we decellularized pulmonary valves root by immersion histology revealing cellular residue, requiring a more efficient approach. We hypothesized that immersion is insufficient and thus a pressure gradient was added.

Material and Method. This is part of a grant approved by the UMFTS. Eleven porcine pulmonary valves were included in the study: n=6 underwent immersion decellularization and n=5 were cyclically perfused with a 20-25mmHg pressure gradient during a 10-day protocol. The acellular valves obtained underwent a quality control using DAPI (4′,6-diamidino-2-phenylindol) nuclear staining, histological Haematoxylin-Eosin, DNA extraction and quantification, harvested from different structural levels: arterial wall, sinus, cusp.

Results. Histological assessments highlighted integrity of extracellular matrix in both groups and overall cells absence at the different levels of valvular structures analyzed. Immersion decellularized valves exhibited DAPI positive structures identified as potential residual nucleic material. Comparatively, the perfusion decellularized valves, lacked in those structures, result confirmed by DNA extraction and quantitation procedure.

Conclusions. Perfusion decellularization represents a feasible approach to obtain acellular cardiac valvular scaffolds derived from the extracellular matrix, being superior to immersion decellularization method. Their nonimmunogenic potential is underlined by total absence of nuclei. The process is fast, allowing production of an abundant number of valvular biomaterials in a short time.

Introduction. The cardiac allograft rejections from the post-transplant period are attributable to the acute cellular rejection monitored by multiple endomyocardial biopsies. Compared to this, humoral rejection remains a matter of debate, with multiple therapeutic strategies, poor prognosis, and persisting uncertainty about diagnostic criteria. Acute allograft rejection is associated with significant modifications of the extracellular matrix compartment mainly regulated by matrix metalloproteinases (MMPs). In this context, the aim of this study was to evaluate the expression of MMP-2 and -9 and CD31, CD68 (endothelial and histiocytic markers) and the correlations between them using immunohistochemistry, in patients with cardiac allografts.

Materials and methods. Tissue fragments were obtained by endomyocardial biopsy from 5 patients with allograft heart transplant, 2 in the medium post-transplant phase and 2 in late phase. After identifying and characterizing the morphological context the probes were processed by standard immunohistochemical technique using anti-MMP-2 and anti-MMP-9 antibodies (Santa Cruz Biotechnology, Inc.) and anti-CD31, anti-CD68 antibodies (Sigma). The samples were examined using the Olympus BX40 microscope with an Olympus E330 camera attached.

Results and discussions. Sample examination revealed in all 4 cases the lack of IR (-) for CD31 and weak IR (+) for CD68 compared to MMPs, where we found moderate IR (++) for MMP-9 and weak IR (+) for MMP-2. These aspects complets the histological lesional aspects of these cases, indicating the lack of acute rejection. In conclusion, CD31 and CD68 IR correlated with MMPs IR (especially MMP-9) appear to represent predictive markers for cardiac allograft rejection and require further studies.

Published: March 2020

Zenker’s diverticulum (ZD) also known as cricopharyngeal (CP), pharyngoesophageal or hypopharyngeal diverticulum is an outpouching of mucosal and submucosal layers originated from the pharyngoesophageal junction. Radiological evaluation of deglutition, modified barium swallow radiography may reveal the retentive character of the diverticular sac and confirm the diagnosis. Many different types of surgical approaches have been developed over the decades with modifications focusing on the need to reduce intra-operative or post-operative complications and overall morbidity. The authors present the case of a 76-years-old woman with spontaneous apparition of an exteriorised tumor in the oral cavity after an excessive cough effort. Surgical treatment is elective, preventing the occurence of complications that may endanger the patients life and improve the quality of life. Surgical therapy was open neck resection of the Zenker’s diverticulum with esophageal myotomy and pharynx reconstruction.

The weaving process is constantly evolving in terms of productivity, quality, and possibilities of fabrication of different fabric structures and shapes. This article covers some issues that have still not been resolved and represents distracting factors in the woven fabrics production. In the development of woven fabric using the CAD technology, it is inevitably a deviation of the virtual image on the computer screen from the woven sample. According to comprehensive industry analyses, the findings of many authors who contributed to the resolution of these problems can be concluded that these problems are still present in the development and production of striped, checkered, and jacquard woven fabrics. In this article, jacquard, multicolor woven fabrics were investigated, with deviations in pattern sizes and shades of color in warp and weft systems compared to virtual simulation on the computer, as well as the tendency of the weft distortion arising from the weaving process leading to the pattern deformation.

Published: March 2020

Endocrinopathies have a variety of orofacial presentations which span from dental malocclusion to facial disfigurement. These characteristics depend on the nature and severity of the condition. An orthodontist should understand the body's physiological processes to be able to timely determine the optimum intervention and plan treatment stages accordingly in compromised individuals. Communication between the two specialties should be well coordinated and should help facilitate quality health care to the patient. This review was aimed to impart the basic knowledge and the pivotal guidelines for orthodontic management in these conditions. Systemic conditions require multidisciplinary management and the dental team should aim to provide quality oral health care to enhance the overall quality of life and the orthodontist plays a vital role in helping patients achieve physical and psychological health.
