Authors: Elbanna Hayat , Zamzam Mohammed Labib , El-Guindy Jylan Fouad , Idris Ahmed Soliman
Published: July 2021

Objective: To evaluate fracture resistance and survival rate of IPS Empress CAD versus Polished Celtra Duo ceramic laminate veneers. Material and Methods: Thirty-six ceramic laminate veneers were fabricated for maxillary anterior teeth. The patients were divided into two groups according to the material Group 1(control group) fabricated from IPS Empress CAD laminate veneers and group 2(intervention group) fabricated from Polished Celtra Duo laminate veneers. Standardized the same preparation with butt joint design and chamfer finish line located supra gingival were performed for all the teeth. The fabrication of the veneers was performed using Cad\Cam (Ceramill motion) machine, with software (Exocad). The veneers surfaces were treated and silanated according to the manufacture instruction of each ceramic and enamel surfaces were etched where total etch adhesive protocol was obeyed using BISCO. Follow up sessions were done every two months up to one year for each patient using dental probe and operator vision to evaluate the fracture, survival rate, marginal adaptation, sensitivity and caries. according to USPHS criteria (United States Public Health Service). This was performed by an experienced, blinded investigator. Results: Fracture resistance, marginal adaptation, retention, caries and sensitivity were evaluated according to the criteria of USPHS and we found there is no significant difference as both groups scaled zero score. Conclusion: Both IPS Empress Cad and Polished Celtra Duo laminate veneers revealed successful clinical performance in terms of fracture resistance, marginal adaptation, retention, and sensitivity after one year follow up period.

Published: July 2021

Objective: The aim of this study is to evaluate the effect of varying thickness and artificial aging on the color and translucency of cubic zirconia and lithium disilicate ceramics. Material and Methods: A total of 30 square shaped disks (12 mm x 12 mm) were fabricated from the cubic zirconia (Bruxzir Anterior) blank and lithium disilicate blocks (E.max CAD), used in three thicknesses (0.5mm, 0.8mm and 1mm). Portable spectrophotometer Vita Easyshade Advance was used to obtain color coordinates, which were substituted in formulas and used to calculate color change and translucency parameter values before and after aging (thermocycling for lithium disilicate and hydrothermal aging for cubic zirconia). Repeated measures Analysis of Variance (ANOVA) was used to study the effect of ceramic type, thickness, aging and their interaction on mean translucency parameter. Two-way (ANOVA) was used to study the effect of ceramic type, thickness and their interaction on mean color change (E). Results: Statistical analysis showed that E.max CAD HT is more translucent than Bruxzir Anterior. Translucency decreased as thickness increased. There was a statistically significant decrease in TP after aging for both materials. Lithium disilicate showed statistically significant greater E when subjected to aging than cubic zirconia, with both E values being clinically imperceptible. As thickness increased, E decreased. Conclusions: Thickness highly affected translucency and color of ceramics. As thickness increases, translucency parameter decreases and color change becomes less evident. Aging also causes a significant decrease in translucency parameter and induces color change however color changes are imperceptible.

O acesso à saúde e a diagnósticos de doenças como o HIV vem sendo facilitado em demanda espontânea através do uso de testes rápidos. Desta forma, cria-se uma circunstância mais favorável para leitura do exame, ampliando o vínculo e garantindo uma atenção resolutiva para o cuidado da paciente. Descrever a importância de uma abordagem integral e cautelosa frente à mulher recém diagnosticada soropositiva e os desafios na adesão ao tratamento e estigma social na APS. Estudo de caso. Paciente 01, 37 anos, casada, com filho de 13 anos, comparece a Unidade desejando realizar o teste rápido de HIV. Seu marido a informou sobre contaminação após uma relação extraconjugal. Foi realizado no mesmo momento aconselhamento pré-teste e teste rápido que se apresentou positivo. A paciente se mostrou apreensiva, com inúmeros questionamentos sobre a vida, sua estrutura familiar e doença, neste primeiro contato foi realizada uma abordagem para melhor entendimento sobre o HIV, esclarecimentos da medicação, exames, meios de contaminação, fortalecimento de vínculo e adesão ao tratamento. Pactuado com a mesma uma continuidade de consultas mensais para o acompanhamento frente a esta realidade. Paciente 02, 22 anos, sem relação estável, comparece a unidade com suspeita de gravidez. Realizado TIG confirmatório, no mesmo momento é iniciado o pré-natal. Durante a consulta foi realizado aconselhamento pré-teste junto aos testes rápidos, HIV e VDRL. No pós-teste o resultado para HIV se apresentou positivo. Informação passada de forma cautelosa, gestante se apresentou abalada e confusa sendo realizado escuta ativa de seus anseios, orientações de tratamento, seguimento da gestação, encaminhamento para serviço de referência especializado e continuidade do cuidado. Compreende-se de fato as dificuldades de aceitação ao diagnóstico de HIV, devido a uma estigmatização social, associação a promiscuidade e carência de informações. Segundo o Ministério da Saúde, a adesão é um processo dinâmico e multifatorial que abrange aspectos físicos, psicológicos, sociais, culturais e comportamentais, e que requer decisões compartilhadas e corresponsabilizadas entre a pessoa que vive com HIV, a equipe de saúde e a rede social. (BRASIL,2013). Desta forma, se mostra mais evidente a necessidade de uma base de acompanhamento multiprofissional, em busca de estratégias para uma abordagem dinâmica, cautelosa, garantia de sigilo, encorajamento ao tratamento e qualidade de vida do portador do HIV.

Músicos apresentam risco aumentado de desenvolver sintomas associados a disfunções do sistema musculoesquelético como dor, fraqueza, dormência, cansaço e outros. Esses sintomas podem estar associados à técnica utilizada para tocar determinado instrumento, tempo de estudo, quantidade e duração dos intervalos, fatores geradores de estresse relacionados ou não à atividade musical, entre outros. A ocorrência de tais sintomas pode impactar negativamente a performance do músico, e até mesmo resultar em afastamento de suas atividades laborais. É importante (re) conhecer os sintomas e os fatores de risco para doenças musculoesqueléticas neste grupo a fim de se desenvolver e implementar estratégias preventivas. Neste contexto, foi criado no Serviço Especializado em Saúde do Trabalhador (SEST) do Hospital das Clínicas da UFMG um programa de atenção integral à saúde do músico. Realizar uma análise descritiva do perfil sócio demográfico, clínico e ocupacional dos músicos que participaram do programa de saúde do músico do SEST. Estudo transversal realizado no período de novembro de 2008 a junho de 2016. Para a coleta de dados, foi aplicado um questionário estruturado durante o acolhimento dos músicos no SEST, o qual é dividido em informações ocupacionais, clínicas e funcionais. Para avaliação da dor, foi usada a versão adaptada para o português do questionário Brief Pain Inventory. Os dados foram analisados utilizando o software SPSS versão 17. Foram avaliados 132 músicos (65% do sexo masculino) com média de idade de 36 anos (DP = 13,2). A maioria (92%) relatou ser instrumentista, sendo mais frequente os instrumentistas de cordas, em sua maioria violonistas (15,9%). Grande parte da amostra estava vinculada a alguma instituição oficial (73%), sendo 36% como aluno e 46% como profissional. O tempo médio de experiência foi 16 anos (DP = 11,4). Sessenta e oito por cento dos músicos realizava estudos regulares, com duração média de 3,5 horas/dia. Em relação a queixas funcionais, 89% apresentou algum tipo de dor, 36% cansaço e 22% fraqueza. A região mais acometida foi o ombro direito (15%), seguida por coluna cervical (13%) e mão direita (9%). Em uma escala de 0 a 10, a dor apresentou média 4 de interferência na atividade ocupacional desses músicos, sendo a média da intensidade de dor relatada igual a 3,6. A prevalência de queixas é semelhante à encontrada na literatura mundial. A experiência do SEST/HC/UFMG tem mostrado que há uma demanda crescente por atendimento no setor público deste grupo de trabalhadores. Conhecer o perfil clínico-ocupacional dos participantes do programa de atenção integral a saúde do músico poderá auxiliar os profissionais de saúde e da música a incorporar estratégias que possam contribuir para a prevenção da ocorrência de disfunções do sistema musculoesquelético nestes trabalhadores.

Authors: Gómez Ramirez Briana Davahiva , Gómez Gutierrez Alejandra Maria
Published: July 2021

Introducción: Un adecuado estado de salud se relaciona con una óptima nutrición. Existe una creciente evidencia que indica que las dietas basadas en plantas como la vegetariana, adecuadamente planeadas, pueden ser completas y aportar una óptima cantidad de calorías y nutrientes para mantener y mejorar la salud y el estado nutricional. Los profesionales del área de la salud y especialmente los nutricionistas dietistas deben guiar a los pacientes que quieren tener una adecuada alimentación vegetariana. El objetivo fue evaluar las actitudes y conocimientos de médicos, nutricionistas, enfermeras y auxiliares de enfermería de una región de Colombia, con relación a las dietas vegetarianas. Material y métodos: Estudio descriptivo transversal, por medio de la aplicación de una encuesta anónima y voluntaria. La encuesta preguntaba sobre la disposición del profesional frente a las dietas vegetarianas y sobre el conocimiento que tenía de las mismas. Resultados: La mayoría de los profesionales (61,7%) se muestran dispuestos a apoyar una dieta vegetariana y el 34% la recomendaría. No obstante, el 18,9% considera que es apropiada para cualquier grupo de edad. Pocos profesionales consideran útil esta dieta para la prevención de enfermedades. También se evidenció que el 55,3% manifestaron que en el entorno hay pocas posibilidades para llevar este tipo de alimentación, destacándose la falta de conocimiento o información. Conclusiones: Se evidencian actitudes desfavorables y brechas en el conocimiento entre los profesionales de la salud en el tema de alimentación vegetariana.

Introduction: Certain weight management methods may be associated with unhealthy dietary intakes, skewing toward certain dietary components and lacking others. Management of weight should not ignore the quality of the diet, as both obesity and poor diet are associated with higher risk of chronic disease. Objective: To conduct a diet quality and exercise scan and observe their repercussion on BMI, in adults from Spain, Portugal, Uruguay and Mexico. Material and methods:An observational retrospective cohort study was designed, with 1181 adults aged 18-65 years. HEI-2010 score was used to assess diet quality. Data on type, days a week and hours/day of exercise, and participant’s anthropometric measures were collected.Results: The mean HEI-2010 score was 65.21. There were no statistically significant differences between HEI-2010 score and BMI [p=0.706], BMI and days of exercise per week [p=0.151], BMI and hours/day of exercise [p=0.590] and BMI and being active [>3 days/week] [p=0.106]. On the contrary, overall exercise influenced BMI significantly [p<0.001]. Conclusions: Dietary patterns may help to prevent weight gain and fight overweight and obesity. This study, however, did not observe associations between the quality of the diet nor specifics of exercise with lower BMIs. The quality of the diet of adults in Spain, Portugal, Uruguay and Mexico fell short of recommendations.
Ivermectin treatment for Strongyloides infection in patients with COVID-19
Authors:   Ontario COVID-19 Science Advisory Table and the Drugs & Biologics Clinical Practice Guidelines Working Group
Published: July 2021

Ivermectin, an antiparasitic agent, is not recommended for prophylaxis or treatment of coronavirus disease 2019 (COVID-19). Inappropriate use of ivermectin for treatment of COVID-19 may make it less available for patients with serious parasitic infections who could benefit from its use and worsen the current shortage of ivermectin in Canada. However, patients with COVID-19 who are candidates to receive immunomodulatory therapies (e.g. corticosteroids and interleukin-6 inhibitors) may be at risk of hyperinfection syndrome and disseminated disease from Strongyloides stercoralis. These complications can be severe and even fatal. It is important to recognize and screen patients who may be at risk of strongyloidiasis, as these patients may require treatment with ivermectin to avoid the potential for a hyperinfection syndrome and disseminated disease, which is frequently deadly. Clinicians should follow evidence-based recommendations to screen and treat for Strongyloides infection in patients with COVID-19 who are under consideration to receive specific COVID-19 therapies that alter immune response and may lead to hyperinfection syndrome or disseminated disease.
Un résumé de la surveillance, de la morbidité et de la microbiologie des cas confirmés en laboratoire de botulisme infantile au Canada, de 1979 à 2019
Authors: Harris Richard , Tchao Christine , Prystajecky Natalie , Cutler Jennifer , Austin John W
Published: July 2021

Contexte : Le botulisme infantile est une maladie toxicoinfectieuse rare causée par la colonisation de l’intestin du nourrisson avec la bactérie clostridia productrice de neurotoxines botuliques (i.e. Clostridium botulinum ou les souches neurotoxiques de C. butyricum ou de C. baratii). Notre objectif était d’examiner les données provenant de cas confirmés en laboratoire de botulisme infantile signalés au Canada afin de résumer l’incidence au fil du temps, en fonction de la répartition géographique par province ou territoire et par sexe, et de comparer ces paramètres avec les données du Système canadien de surveillance des maladies à déclaration obligatoire (SCSMDO). L’âge moyen de l’apparition des symptômes, le sérotype de la neurotoxine botulique (NTBo), les résultats du cas, la durée de l’hospitalisation et la pertinence des échantillons cliniques pour la confirmation en laboratoire ont également été déterminés. Méthodes : Nous avons examiné les dossiers de laboratoire du Service de référence sur le botulisme de Santé Canada et du laboratoire de santé publique du Centre de contrôle des maladies de la Colombie-Britannique. La Base de données sur les congés des patients (BDCP) et la Base de données sur la morbidité hospitalière (BDMH) de l’Institut canadien d’information sur la santé (ICIS) ont été interrogées pour obtenir des données sur les hospitalisations pour des cas de botulisme infantile. Le SCSMDO a été consulté pour obtenir des données sur les cas signalés de botulisme infantile. Résultats : De 1979 à 2019, 63 cas confirmés en laboratoire de botulisme infantile ont été confirmés par le Service de référence sur le botulisme de Santé Canada et le laboratoire de santé publique du Centre de contrôle des maladies de la Colombie-Britannique pour un taux annuel de 4,30 cas par million de naissances vivantes. De 1983 à 2018, 57 cas de botulisme infantile ont été signalés au SCSMDO. Sur les 63 cas confirmés par les laboratoires de référence, l’âge médian de l’apparition des symptômes était de 16 semaines avec un intervalle de deux à 52 semaines. La majorité des cas étaient de type A (76 %) et B (21 %), avec des cas uniques de type F et de type AB. Sur les 23 cas confirmés en laboratoire avec des dossiers hospitaliers jumelés, 13 ont été transférés à des soins spéciaux et huit ont eu besoin du soutien d’un respirateur; aucun décès n’a été signalé. Conclusion : Les spores de C. botulinum sont présentes naturellement dans l’environnement, de sorte que le diagnostic de botulisme infantile ne nécessite pas d’antécédents d’exposition à des aliments à risque élevé comme le miel. Les échantillons de selle sont les échantillons de diagnostic les plus utiles.
Possibilité d’intensification des efforts de dépistage et de recherche de contacts pour prévenir les nouvelles éclosions de COVID-19 attribuables à des variants plus transmissibles
Authors: Wu Jianhong
Published: July 2021

Contexte : Lorsque les interventions de santé publique sont assouplies après plusieurs jours de baisse du nombre de cas de maladie à coronavirus 2019 (COVID-19), il est essentiel de déterminer les stratégies potentielles pour assouplir les restrictions tout en atténuant le risque d’une nouvelle vague de variants préoccupants plus transmissibles. Nous avons estimé les améliorations nécessaires aux interventions en santé publique pour une réouverture partielle de l’économie tout en évitant les pires conséquences d’une nouvelle éclosion, associées à des variants préoccupants plus transmissibles. Méthodes : Un modèle dynamique de transmission a été utilisé pour quantifier les conditions auxquelles les interventions de santé publique combinées doivent répondre pour rouvrir l’économie sans risque d’éclosion importante. Ces conditions sont celles qui maintiennent le taux de reproduction de contrôle en dessous de l’unité, tout en tenant compte d’une augmentation de la transmissibilité due aux variants préoccupants. Résultats : Il a été possible de déterminer des combinaisons de la proportion de personnes exposées au virus qui sont retracées et mises en quarantaine avant de devenir infectieuses, la proportion de personnes symptomatiques confirmée et isolée et les taux de contact quotidiens individuels nécessaires pour s’assurer que le taux de reproduction de contrôle demeure inférieur à l’unité. Conclusion : Notre analyse indique que le succès des mesures restrictives, notamment les décrets de confinement et les fermetures, offre une fenêtre d’opportunité étroite pour intensifier les efforts de détection des cas et de recherche des contacts afin d’empêcher une nouvelle vague associée à la circulation de variants préoccupants plus transmissibles, comme en témoigne la réduction du nombre de cas.
RPEiS – interdyscyplinarne długie trwanie, dokonania i wyzwania

Published: July 2021

Tekst ma charakter okolicznościowy. Został przygotowany z okazji 100-lecia powstania czasopisma „Ruch Prawniczy, Ekonomiczny i Socjologiczny” (RPEiS). We współczesnym, wysoce turbulentnym świecie, świecie narastającej niepewności co do przyszłych kierunków przemian, w świecie nasilającego się Talebowskiego syndromu czarnego łabędzia, długie trwanie można uznać za sukces sam w sobie. Wiele wskazuje, że źródłem tego sukcesu jest interdyscyplinarny charakter RPEiS i wysoka merytoryczna jakość oraz holizm publikowanych w tym czasopiśmie tekstów. Mają one wymiar naukowo-badawczy, popularyzatorski, edukacyjny i ekspercko-konsultacyjny. Tworzy to korzystne podłoże dla rozwoju relatywnie nowego nurtu badawczego, jakim jest ekonomiczna analiza prawa. Jest to istotne tym bardziej, że ten obszar dociekań naukowo-badawczych nie doczekał się jeszcze należytego miejsca w polskiej rzeczywistości.
On split quaternion equivalents for Quaternaccis, shortly Split Quaternaccis
Authors: Bajorska-Harapińska Beata , Ludew Jakub Jan , Smoleń-Duda Barbara , Wituła Roman
Published: July 2021

In this paper, we introduce generalizations of Quaternacci sequences (Quaternaccis), called Split Quaternacci sequences, which arose on a base of split quaternion algebras. Explicit and recurrent formulae for Split Quaternacci sequences are given, as well as generating functions. Also, matrices related to Split Quaternaccis sequences are investigated. Moreover, new identities connecting Horadam sequences with other known sequences are generated. Analogous identities for Horadam quaternions and split Horadam quaternions are proved.

Published: July 2021

Using single-shot velocity map imaging technique, explosion imaging of different ion species ejected from 50 nm SiO2 nanoparticles are obtained excitedly by strong near-infrared and ultraviolet femtosecond laser fields. Characteristic momentum distributions showing forward emission of the ions at low excitation intensities and shock wave behaviors at high intensities are observed. When the excitation intensity is close to the dissociative ionization threshold of the surface molecules, the resulting ion products can be used to image the instant near-field distributions. The underlying dynamics of shock formation are simulated by using a Coulomb explosion model. Our results allow one to distinguish the ultrafast strong-field response of various molecular species in nanosystems and will open a new way for further exploration of the underlying dynamics of laser-and-nanoparticle interactions.
A (Lay) Catholic Voice Against a National Consensus
Authors: Mullins Patrick James
Published: July 2021

In both a canon law student’s essay and in oral remarks to the 2017 Onclin Chair conference at KU Leuven, the author critiques his own country’s closed border consensus excluding admission of boat people. He argues this political consensus in Australia is at odds with the celebrated national identity of Australians. Moreover, the author identifies that the closed border consensus is contrary to the Gospel, because it does not welcome the stranger and because it betrays the universality of the love of neighbour which the Gospel demands. The author argues that the voice of the Catholic lay person is not to remain silent, but is to speak out against the injustice of the policy because the Gospel, the magisterium of the Second Vatican Council in its decree on the Apostolate of the laity, the Canon law, Catholic moral theology and the dictates of conscience all demand the articulation of a contrary view.
‘Next Time You Should be More Friendly!’ The Value of Social Drinking in the Babylonian Letter BM 108890
Authors: de Ridder Jacob Jan , Zomer Elyze
Published: July 2021

This paper presents a first edition of the Middle Babylonian letter BM 108890. The unknown author complains bitterly about the inhospitable treatment he has received. Reflective of the author’s mood is the lack of introduction and formal greeting. Since a direct reference is made to Nippur, it is likely that this tablet originates from central Babylonia.
How Numerous and How Busy were Late-Antique Presbyters?
Authors: Wiśniewski Robert
Published: July 2021

This article seeks to count late-antique clergy and assess their workload. It estimates the number of clerics, and particularly presbyters, in Christian communities of various sizes, and investigates how and why the ratio of clerics to laypersons changed over time. First, by examining the situation in the city of Rome, it demonstrates that the growth in the ranks of the presbyters from the third to the fifth century was slow, and argues that this resulted from the competing interests of the bishops, lay congregation, rich donors, and above all the middle clergy. It is the last group who were reluctant to raise their number as this had a negative impact on their income. The results of this phenomenon can also be seen in other big sees of Christendom, in which, in Late Antiquity, there was one presbyter per several thousand laypersons. Interestingly, in smaller towns, this ratio was significantly lower, and in the countryside, it remained in the lower hundreds. Second, this article shows how the changing ratio of clerics to laypersons affected the level of professionalization of the former. In the big cities, the ecclesiastical duties of presbyters who served in a growing community were getting heavier. This turned the presbyters into full-time religious ministers, at the same time making them even more dependent on ecclesiastical income. In the towns and villages, however, the pattern was different. In the places in which one presbyter served a very small community, his job was less time-consuming but also brought him less income. In consequence, rural presbyters had to support their families through craft work, commerce, or farming, and they had time for this.
Audientia sacerdotalis?—Remarks on the Legal Nature of Dispute Resolution by Ecclesiastics in Late Antiquity
Authors: Wojtczak Marzena
Published: July 2021

The problem of audientia episcopalis in late antiquity has been the subject of extensive research in the past. Previous studies have usually focussed on the legal doctrine, as well as the picture of bishop courts in the light of the literary sources. In contrast, the question of how audientia episcopalis functioned in the legal practice as shown by papyri has caused scholars much difficulty, due to the limited material available as well as the obscure nature of the institution. One could therefore ask: how is it possible that such allegedly common practice of dispute resolution by the bishops—as literary sources make us believe—is so elusive in the papyri? How to explain the simultaneous increase for that period of the papyrological attestations regarding arbitration/mediation carried out by the clergy of lower rank? Could we be dealing with some sort of audientia sacerdotalis functioning in the legal practice? How widespread was in fact the audientia episcopalis, and was this institution homogeneous or rather heterogeneous in nature? The paper presents the attempt to answer these questions by confronting the imperial law with the evidence of legal practice.
Listening for the Pictures
Authors: Cheers D. Michael
Published: July 2021

This essay is inspired by the words of Pulitzer Prize–winning Chicago Sun Times photographer John White, who once told me to “listen for the pictures.” His message rang clear but never more so than when in 1990 we were covering the release of Nelson Mandela in Cape Town, South Africa. The Cape Town scene was alive and filled with so much vibrance. I was keenly aware that I must not just look, but I must listen, and use all my God-given senses to take it in. I can only describe the moment I started listening to the layer of sound, which was my own clicking camera superimposed on the chorus of sounds that surrounded me as both meta and sonorific. There was a certain rhythm to the sensation I felt in being one with my camera. It transported me to a wonderful place in time where visuals and cadences danced together.

I realized there was alchemy in this and in all the other moments and locations I had spent behind a camera developing and exercising that “inner ear” my ancestors, some gone, like Gordon Parks, but others here, like White, taught me to revere. This essay is a snapshot of some of those moments—a proof sheet, if you will—from a life that began, as did the civil rights era, with instances of terror and triumph. This essay chronicles my journey as a young photographer and the many influences that shaped my creative process and eventually my worldview. This essay is an invitation to travel with me through time and see life as my camera and I witnessed it, and to hear and sense the world as I do.
Advanced treatment of salty eutrophication water using algal-bacterial granular sludge: With focus on nitrogen removal, phosphorus removal, and lipid accumulation
Authors: Meng Fansheng , Liu Yu , Zhang Ping , Liu Dongfang , Huang Wenli
Published: July 2021

A new algal-bacterial granular sludge treatment method was used to treat salty eutrophication water. The results indicated that the treatment removed more than 98% of the total inorganic nitrogen and the total phosphorus after a 15 d cultivation period using 2% salinity simulated eutrophication water. For the 4% salinity simulated water, the total phosphorus was not able to be removed and was even higher in the effluent; and the total inorganic nitrogen was only removed 17%. Thus, the algal-bacterial granules were efficient for removing nitrogen and phosphorus in 2% salinity eutrophication water but were not effective for 4% salinity water. High levels of filamentous algae proliferation growing on the surface of the granules was primarily responsible for the good performance in 2% salinity water. However, the lipid accumulation was greatly enhanced (reactor R2 at a 27.6% increase and reactor R4 at a 107% increase) for both granule types due to the algal growth. Thus, treatment of the salty eutrophication water can also greatly increase the added-value of the algal-bacterial granules.

Published: July 2021

Introducción: en los últimos años se han descrito alteraciones genéticas asociadas con un mayor o menor riesgo de padecer una enfermedad trombótica. El objetivo del presente estudio es conocer la prevalencia de las mutaciones para la metilentetrahidrofolato reductasa (MTHFR), la protrombina (II G20210G/G20210A) y el factor V Leyden en las muestras de pacientes sometidas a estudio por perfil trombofílico en el Hospital San Vicente de Paúl. Metodología: con la base de datos de muestras referidas del Hospital San Vicente de Paúl, se estudiaron los marcadores de riesgo para trombofilia: MTHFR, Ac Lúpico, mutación del Factor II y Factor V Leyden correspondientes al periodo comprendido entre abril de 2017 a abril de 2018. Resultados: se observó que la frecuencia de la solicitud de estudio por trombofilia era mayor para el sexo femenino, con un 83,7 % del total de análisis, mientras que, para el sexo masculino fue de un 16,3 %. La mutación más prevalente fue la MTHFR, seguida del factor V Leyden, además, ambas se presentaron superiormente en las mujeres. Conclusión: se ha demostrado en varios estudios la asociación de las alteraciones genéticas estudiadas con los eventos trombóticos, por lo tanto, conocer su prevalencia en determinada población es de gran importancia para ayudar al clínico a llegar a un diagnóstico adecuado.

Objective: To evaluate the monthly rates of hospitalizations for childhood diarrhea in macro-regions of Araçatuba, Marília and Presidente Prudente, SP, between 2019 -June Between June 2009. Methods: The average rates and their standard deviations for admission of diarrhea in the target population were obtained from DATASUS and standardized for cases x 100,000 inhabitants. Confidence limits were established, occurrences above confidence limits were considered epidemic events. The normality of the data and serial autocorrelation were tested using the Shapiro-Wilk and Durbin-Watson method. Results: All methods detected epidemic occurrences in the three regions. Araçatuba and Marília, the peaks were concentrated in the first half of the decade and Presidente Prudente, close to the middle. The CUSUM method was more sensitive to detect epidemic periods, however the normality data and assumptions have been violated by serial autocorrelation in a few months. The EWMA method was considered the most appropriate. Conclusions: Statistical process control charts can be used to monitor and compare disease incidence between different regions.

Published: July 2021

Introducción. La pandemia de COVID-19 ha visibilizado la situación actual de los sistemas y las condiciones de salud de la población en todo el mundo. Objetivo. Analizar las condiciones de salud de la población en México, sobre todo en el grupo de 45 a 59 años, y cómo las enfermedades no transmisibles y la edad son factores de mal pronóstico para COVID-19, a fin de mostrar al envejecimiento saludable como una alternativa para replantear las políticas públicas. Argumentos para la discusión. Se requiere que el grupo etario de 45 a 59 años sea considerado como objetivo dentro de la cobertura del Paquete Garantizado de Servicios de Salud, cuyas acciones se aplican en todo el sector a manera de medicina preventiva; esto, porque actualmente está incluido en un grupo etario más amplio y se debe tomar en cuenta el incremento de la mortalidad asociada con la edad y la comorbilidad ocurrida por la pandemia. Conclusiones. México demanda un replanteamiento sobre la política pública de envejecimiento saludable, mediante la implementación de estrategias y acciones en todo el curso de vida, pero de forma urgente durante la segunda mitad, después de los 45 años, con medidas de prevención secundaria de enfermedades no transmisibles, ya que es a partir de esta edad y hasta los 79 años donde se han presentado la mayor cantidad de defunciones por COVID-19; de tal modo, se busca enfrentar con mejores condiciones de salud de la población las siguientes pandemias que se presenten.
Logistic and environmental quality

Logistic performance has been improved tremendously in many parts of the world. Nonetheless, its improvement does not necessarily guarantee that environmental quality can be preserved. Hence, it is the objective of this study to examine the effect of logistic improvement on environmental degradation in developing countries. Applying dynamic panel model estimator for a panel of 50 developing countries for the period between 2010 and 2016, this study observes that the level of pollution tends to be higher with a higher level of logistic performance. The findings show that developing countries that did not adopt green practices on logistic performance pose negative effects in terms of air pollution, climate change, and global warming. Thus, the efforts to reduce environmental degradation must be comprehensive enough and the priority of environmental policies should be in the first place, targeting logistic performance. In other words, performance measure of logistic should also take into account its contribution to environmental quality.

The general warming trend of the planet cannot be denied (the average global air temperature has increased by approx. 0.85°C between 1880-2012 (IPCC, 2013). The direct consequence of this warming is an increase in extreme weather events and hence in climate risks. The monitoring and assessing precipitation, identifying the physical laws governing its course in order to be able to estimate and forecast it in the future is therefore of great interest nowadays. Using geostatistical spatial analysis methods, this paper aims at identifying the correlations between longitude and precipitation (due to the specificity of the European climate, given by the major influence of the western circulation) and then an estimation - using linear regression equations - of precipitation amounts depending on longitude. Two variables were calculated for the statistical analysis: the proportion of the mean number of days with precipitation ≥ 10 mm of the multiannual mean of precipitation days (≥0,1 mm) and the precipitation ratio between the mean precipitation quantities in summer, compared to those in winter (hereinafter referred to as summer/winter precipitation ratio). The geostatistical analysis carried out on a sample of 40 weather stations aligned from west-south-west to east-north-east argues the existence of a strong correlation between longitude and the multiannual mean of days with precipitation ≥10 mm and between longitude and the summer/winter precipitation ratio.

The study of land cover and use changes is important for sustainability, given that they are part of the global changes affecting our environment. In order to understand the mechanisms determining them, land cover and use changes must be studied based on their associated transitional dynamics. The present research aims to look at the most recent land cover and use changes from Romania, chosen as an example for post-socialists transitions. The methodology was based on applying geo-spatial analyses to data on land cover and use changes and natural protected areas. The results indicate that the most prominent transitional dynamics are deforestations and abandonment of cropland, rooted in the post-socialist property restitution. Furthermore, the study identified transitional dynamics indicating the human pressure within the natural protected areas, including urbanization, development of agriculture, and deforestation. Although subject to limitations bound to the use of CORINE data, the findings are important for understanding the environmental impact of socio-economic drivers, and provide additional evidence for the fact that emerging economies tend to sacrifice the environment during the economic crises.

Sustainable development is now a key factor in the global economy. Sustainable development is a process that leads to the satisfaction of the current needs of people and at the same time goes towards further development without destroying and limiting the possibilities of meeting the needs of future generations. Therefore, joint efforts should be made as soon as possible to build a sustainable and safe future for all people and the planet as a whole. Therefore, it is important to promote and support sustainable development by managing natural resources and ecosystems and the entire environment including people. The presented research was done on-site in African and European countries (Egypt, Ethiopia, Guinea, Turkey, and Poland) to determine their level of sustainable development. The level of sustainable development was determined by selected indicators from the Human Development Index. The level of sustainable development was determined by selected indicators from the Human Development Index. In this study, the authors used basic methods of social and economic research as follows: (1) market observation, (2) primary research on-site and (3) secondary research and the use of statistical analysis (Pearson Correlation). These methods were used to define the social and scientific problems and identify factors that affected a country's sustainable development. The main scientific problem, addressed by the study was undertaken in order to help facilitate a outcome on the energy, food and agricultural sectors connected with climate change and environmental law. It was found that there is an extremely strong positive correlation (from 0.8 to 1.0), and a very strong negative correlation (from -0.8 to -1.0) between the levels of a country’s age share, CO2 emissions, renewable energy consumption, and natural resources depletion.

The shelf life of sour milk dessert has been substantiated based on the results of this study into the indicators of active acidity, water activity, enthalpy, and organoleptic properties. In addition, the content analysis of lactic acid bacteria and microbiological indicators in the finished product during storage was performed. It was found that the introduction of sublimated fruits together with whey protein concentrate reduces the water activity index from 0.984 to 0.972 by increasing the concentration of solids and product viscosity.
The active acidity indicator acts in combination with the water activity on the shelf life of food products. Active acidity during the study period was in the range of 5.4‒4.2 pH units.
The biological and physiological value of the fermented milk product will increase due to the use of a starter culture containing microorganisms of bifidobacteria and lactobacilli, which include Streptococcus thermophilus, Lactobacillus delbrueckii ssp. Bulgaricus, Lactobacillus acidophilus, Bifidobacterium lactis, Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus paracasei, Bifidobacterium infantis. When storing sour milk dessert for more than 3 days, the number of bacteria came down and was 1.0×108 CFU/g on day 9, which meets the regulatory requirements.
Based on the results of microbiological indicators, the shelf life of the sour milk dessert was established, which should not exceed 5 days at a temperature of 4±2 °С.
The development and improvement of sour milk desserts using secondary milk raw materials is a promising area of scientific research. This would allow the development of waste-free technologies with the maximum use of useful components that are included in the secondary milk raw materials

This paper reports a study into the dependence of efficient glycerate potassium production involving glycerin and potassium hydroxide solution on the process conditions. The concentration of potassium glycerate in the resulting product has been used as a parameter of the efficient glycerate potassium production process.
Glycerates of metals are applied to produce articles in the construction industry, electronics, medicine; they are employed as transesterification catalysts to obtain special fats for various purposes, as well as biodiesel fuel.
In order to derive potassium glycerate, heating was applied while agitating a mixture of glycerin and potassium hydroxide.
The analysis of potassium hydroxide was performed, in which the basic substance mass fraction was 85.5 %, the mass fraction of carbonate potassium – 0.9 %. The p.a.-grade glycerin was applied in this work, whose basic substance mass fraction was 99.5 %.
The effect of the heating temperature of the reaction mixture on the concentration of potassium glycerate in the product has been determined. It has been shown that the rational heating temperature is 145 °C.
The dependence of potassium glycerate concentration in the resulting product on the following conditions of the process has been established: a change in the molar concentration of glycerin and a reaction mixture heating duration.
Such rational conditions for obtaining potassium glycerate have been defined as a molar concentration of glycerin of 60 % and a heating duration of 4 hours. The experimentally established concentration of potassium glycerate in the product under these conditions was 75.77 %.
For potassium glycerate, the melting point (69 °C) and the mass fraction of moisture (0.8 %) have been determined.
The results of experimental studies would make it possible to obtain potassium glycerate directly at enterprises where the glycerates of metals are used, from available raw materials, under rational conditions. The defined conditions for obtaining potassium glycerate could make it possible to efficiently utilize material and energy resources.

The study reported here has revealed the issue related to the inefficient scaling of the uniformity of jacket model designs in the processes involving a typical representative as a result of modification parameters uncertainty.
A variant has been proposed to synchronize the critical points of silhouetted allowances by grouping the numeric series in the vector of choosing the value for an increase in the allowance according to the characteristics of style varieties. The influence of shape-forming segmentation on the formation of a classifier of the structural and technological solutions for a jacket has been determined. The built model to support modification vectors has made it possible to describe the sequence of procedures execution by the method of typical representation. The presence of one design category, the same structural parts, the uniformity of style simplifies the processes of choosing and selecting the most characteristic models of the jacket.
It was found that the morphological combination of attributes of the physical appearance affects the adjustment of style preferences in a manufacturer’s products. The parameters for typical segmentation relative to the junction points of the structural zones of the optimized five-seam prototype design have been defined as the most influential vectors of jacket modification.
A method for scaling the allowance for free fitting has been devised on the basis of data from empirical research. An adequate regression model has been derived for normalizing the silhouette allowance parameters. The constructed model makes it possible to scale silhouette structures by changing the increments at the corner points of the contour according to the prototype of gradation under an automated mode.
Practical recommendations have been compiled on the parameters of zonal-modular modification of silhouette designs of jacket varieties: a linear character of the state silhouetted transformation relative to ASi1=5 cm. The normalized parameters for constructing functional and decorative parts have been proposed
