Automation of the air conditioning system for aseptic rooms of pharmaceutical production

<span lang="EN-US">As modern control systems are becoming more complex, and the implemented technology more sophisticated, the importance of the different characteristics of those systems, such as reliability, availability, security, and protection, is increasing. In this article, an automation design for the air conditioning system of classified areas of the Parenteral solutions plant of the eastern pharmaceutical laboratory company of Santiago de Cuba province, Cuba, is proposed because there is a lack of optimal environmental conditions for development and production of pharmaceuticals at a large scale. The proposal is focused on the design of a supervision system and automatic control of the environmental variables that influence the drug production process. The entire algorithm for the design was developed to monitor critical and non-critical variables and control values of temperature, relative humidity, differential pressure, and air velocity according to standards established by pharmaceutical companies. The design of the automation system includes, apart from the control and supervision algorithm for operation efficiency, the necessary instrumentation.</span>

Two new records of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae) from cyprinids fishes farmed in Cuba

Two monogeneans species were collected from gills of Labeo, Labeo rohita (Hamilton, 1822) and silver carp, Hypophthalmichthys molitrix Valenciennes, 1844 of four localities in the country: "La Sierpe" Fish hatchery and Zaza reservoir (Sancti Spíritus province); "Carlos Manuel de Céspedes" Fish hatchery (Santiago de Cuba province); and in the Aquaculture Technologies Company, EDTA (Havana province). The two species were identified according to their morphological characteristics and morphometric measures as Dactylogyrus labei Musselius and Gussev, 1976 (Gussev, 1976) from L. rohita; and Dactylogyrus hypophthalmichthys Achmerow, 1952 from H. molitrix. The collected parasites were set in ammonium-picrate and glycerin solution, and mounted in gelatin glycerin. Drawings, digital images and morphometric data were presented for each species. These new monogeneans records for Cuba also represent a new world geographical location.

A New Cost-Benefit Economic Model Approach of Hemodialyzer Reuse

In this study, a new cost-benefit economic model for hemodialyzer reuse has been developed considering all of the direct costs (dialyzer price, disinfection fluid price, reverse osmosis water cost, personnel, and miscellaneous) as well as the number of disinfections applied to the hemodialyzer. The maximum number of disinfections/reuses for different models of hemodialyzer was estimated using statistical analysis based on the information obtained from a total of 60 adult patients on maintenance hemodialysis for approximately 4 years; from a hospital in Santiago de Cuba province, Cuba. An equal number of treatments (100) was evaluated for each hemodialyzer including 2,800 total reuses. The total cost savings for reuse/disinfection using the new economic approach is compared with the single-use modality. Obtained results by applying the proposed model indicated that the correlation between the economic advantages of the reuse/disinfection process in the total cost of the hemodialysis treatment significantly depends on the type of hemodialyzer used for the treatment, the disinfection price, the virgin hemodialyzer price, the disposal cost and its price reduction because of the number of reuses and the maximum possible reuses that could be applied to the hemodialyzer.

Coastal Migration Index for Coastal Flooding Events Increased by Sea Level Rise due to Climate Change: Mexico and Cuba Case Studies

This paper presents a coastal migration index (CMI) useful for decision-making in the current scenario of sea-level rise (SLR) due to climate change. The CMI includes coastal human population density, degree of urbanization, and coastal-flooding penetration. Quantitative and qualitative statistical techniques and the geographic information system ArcGIS View 9.0 were used. Further, a panel of fifteen international experts in coastal management issues was consulted to establish and validate the CMI. Results led to three index components based on 22 indicators. CMI was applied in the state of Tamaulipas, Mexico and in Santiago de Cuba province, Cuba. According to CMI estimates, the risk levels associated with SLR for human settlements analyzed in Mexico and Cuba were 5.3% and 11.0%, respectively. The most severely affected communities will require resettlement. Meanwhile, the CMI determined that 15.8% of the Mexican territory studied will be able to withstand the effects of SLR through the management of engineering works that will protect human settlements. The CMI determined that 79.0%, in the case of Tamaulipas, as well as 89.0% of the Cuban territory, will not require new policies or guidelines to promote conservation and protection of coastal natural resources. Lastly, the method used allowed for creation of a CMI stoplight map useful to coastal decision-makers to adopt sound management actions.

Aplicación de una jalea de caléndula al 1% en pacientes con alveolitis

Objetivo: demostrar los beneficios terapéuticos del uso de una jalea de caléndula al 1% en pacientes con alveolitis. Métodos: se realizó una intervención terapéutica en el Policlínico Julián Grimau, provincia Santiago de Cuba, Cuba, entre enero y junio de 2019. Por muestreo no probabilístico se reclutó una muestra de 24 pacientes con diagnóstico de alveolitis seca o húmeda, distribuyéndose en dos grupos: A (control) y B (estudio), los cuales recibieron tratamiento convencional y jalea de caléndula al 1%, respectivamente. Se analizaron las variables: edad, sexo, tipo de alveolitis, tiempo de remisión del dolor y de cicatrización, respuesta al tratamiento (mejorado y no mejorado) y beneficios terapéuticos. Se empleó el porcentaje como medida de resumen y el test estadístico Ji al cuadrado de Independencia con un nivel de significación (a) de 0,05. Resultados: se evidenció un predominio de la alveolitis en pacientes con 19-59 años de edad (50,0%), del sexo femenino (66,7%) y del tipo húmeda (75,0%). En ambos grupos de tratamiento, el mayor porcentaje de los pacientes (17) refirió alivio del dolor a las 48 horas. En el 83,3% de los pacientes, incluidos en el grupo B, se observó menor tiempo de cicatrización. El 100% de los pacientes se categorizó como mejorado. Conclusiones: la jalea de caléndula al 1% resulta beneficiosa, dada su capacidad analgésica y cicatrizante en el tratamiento de pacientes con alveolitis.

New Records of Polymita venusta (Gmelin, 1792) Populations in Northern Foothills of Sierra de Boniato, Santiago de Cuba Province

Three new localities of Polymita venusta are uncovered from the northern foothills of Sierra de Boniato in the Santiago de Cuba province. In those, five new populations inhabiting fragmented forests over karstic substratum were found between 238-405 meters above sea level. The rediscovery of a unique color form took place in one colony from the La Luz vicinity. These populations occupy a highly deforested area where the main activities are cattle grazing and agriculture, combined with other anthropic threats. Protected Areas planning for this human highly disturbed zone is nonexistent.

Mathematical modeling and forecasting of COVID-19: experience in Santiago de Cuba province

In the province of Santiago de Cuba, Cuba, the COVID-19 epidemic has a limited progression that shows an early small-number peak of infections. Most published mathematical models fit data with high numbers of confirmed cases. In contrast, small numbers of cases make it difficult to predict the course of the epidemic. We present two known models adapted to capture the noisy dynamics of COVID-19 in the Santiago de Cuba province. Parameters of both models were estimated using the approximate-Bayesian-computation framework with dedicated error laws. One parameter of each model was updated on key dates of travel restrictions. Both models approximately predicted the infection peak and the end of the COVID-19 epidemic in Santiago de Cuba. The first model predicted 57 reported cases and 16 unreported cases. Additionally, it estimated six initially exposed persons. The second model forecasted 51 confirmed cases at the end of the epidemic. In conclusion, an opportune epidemiological investigation, along with the low number of initially exposed individuals, might partly explain the favorable evolution of the COVID-19 epidemic in Santiago de Cuba. With the available data, the simplest model predicted the epidemic evolution with greater precision, and the more complex model helped to explain the epidemic phenomenology.

Redescription of Tetragnatha guatemalensis, T. laboriosa and T. jaculator, with new synonymies of genus Tetragnatha (Araneae: Tetragnathidae) in the Neotropical Region

ABSTRACT We redescribe three species of the long-jawed orb-weaving spiders of the cosmopolitan genus Tetragnatha based on specimens from the Neotropical Region, all recorded from South America for the first time. Tetragnatha guatemalensis O. Pickard-Cambridge, 1889 is newly recorded from Brazil (Rondônia, Tocantins, Mato Grosso do Sul, São Paulo, Santa Catarina and Rio Grande do Sul states). Tetragnatha laboriosa Hentz, 1850 is newly recorded from Cuba (Santiago de Cuba province), Dominican Republic (Bahoruco province), Brazil (Sergipe, São Paulo and Rio Grande do Sul states), Chile (Valparaíso province), Paraguay (Misiones province) and Argentina (Corrientes, Neuquén, Río Negro and Santa Cruz provinces). Tetragnatha jaculator Tullgren, 1910 is newly recorded from Cuba (Holguín province), some states of Brazil (Pará, Maranhão, Paraíba, Pernambuco, Sergipe, Mato Grosso do Sul, São Paulo, Paraná and Santa Catarina) and Chile (Malleco commune). Finally, we proposed six new synonymies for these species.

Micromonospora fluminis sp. nov., isolated from mountain river sediment.

During a bioprospection of bacteria with antimicrobial activity, the actinomycete strain A38T was isolated from a sediment sample of the Carpintero river located in the Gran Piedra Mountains, Santiago de Cuba province (Cuba). This strain was identified as a member of the genus Micromonospora by means of a polyphasic taxonomy study. Strain A38T was an aerobic Gram-positive filamentous bacterium that produced single spores in a well-developed vegetative mycelium. An aerial mycelium was absent. The cell wall contained meso-diaminopimelic acid and the whole-cell sugars were glucose, mannose, ribose and xylose. The major cellular fatty acids were isoC15:0, 10 methyl C17:0, anteiso-C17:0 and iso-C17:0. The predominant menaquinones were MK-10(H4) and MK-10(H6). Phylogenetic analysis of 16S rRNA gene sequences revealed that this strain was closely related to Micromonospora tulbaghiae DSM 45142T (99.5 %), Micromonospora citrea DSM 43903T (99.4 %), Micromonospora marina DSM 45555T (99.4 %), Micromonospora maritima DSM 45782T (99.3 %), Micromonospora sediminicola DSM 45794T (99.3 %), Micromonospora aurantiaca DSM 43813T (99.2 %) and Micromonospora chaiyaphumensis DSM 45246T (99.2 %). The results of OrthoANIu analysis showed the highest similarity to Micromonospora chalcea DSM 43026T (96.4 %). However, the 16S rRNA and gyrB gene sequence-based phylogeny and phenotypic characteristics provided support to distinguish strain A38T as a novel species. On the basis of the results presented here, we propose to classify strain A38T (=LMG 30467T=CECT 30034T) as the type strain of the novel species Micromonospora fluminis sp. nov.

Nocardiopsis dassonvillei subsp. crassaminis subsp. nov., isolated from freshwater sediment, and reappraisal of Nocardiopsis alborubida Grund and Kroppenstedt 1990 emend. Nouioui et al. 2018.

An actinomycete, strain D1T, was isolated from a freshwater sediment sample collected from the San Pablo river in the La Risueña community, Santiago de Cuba province, Cuba. The strain was identified as a member of the genus Nocardiopsis by means of a polyphasic taxonomic study. It produced a light yellow non-fragmented substrate mycelium, a white well-developed aerial mycelium and straight to flexuous hyphae. No specific spore chains were observed. Strain D1T contained meso-diaminopimelic acid, no diagnostic sugars, and MK-10(H2), MK-10(H4), MK-10 and MK-10(H6) as predominant menaquinones, but not phosphatidylcholine as diagnostic polar lipid of the genus Nocardiopsis. The predominant fatty acids were iso-C16 : 0, 10-methyl-C18 : 0 and anteiso-C17 : 0. Strain D1T showed the highest degree of 16S rRNA gene sequence similarity to Nocardiopsis synnematoformans DSM 44143T (99.8 %), Nocardiopsis dassonvillei subsp. albirubida NBRC 13392T (99.8 %) and Nocardiopsis dassonvillei subsp. dassonvillei DSM 43111T (99.6 %). A genomic OrthoANIu value between D1T and N. dassonvillei subsp. dassonvillei DSM 43111T of 97.63 % and a dDDH value of 78.9 % indicated that strain D1T should be classified in N. dassonvillei. However, phenotypic characteristics distinguished strain D1T from its nearest neighbour taxon. On basis of these results we propose to classify strain D1T (=LMG 30468T=CECT 30033T) as a representative of a novel subspecies of the genus Nocardiopsis, for which the name Nocardiopsis dassonvillei subsp. crassaminis subsp. nov. is proposed. In addition, the genomic distance between N. dassonvillei subsp. albirubida NBRC 13392T and N. dassonvillei subsp. dassonvillei DSM 43111T as determined through OrthoANIu (93.64 %) and dDDH (53.40 %), along with considerable phenotypic and chemotaxonomic differences reported in earlier studies, indicated that the classification of this taxon as Nocardiopsis alborubida Grund and Kroppenstedt 1990 is to be preferred over its classification as N. dassonvillei subsp. albirubida Evtushenko et al. 2000.

Application of Business Intelligence in studies management of Hazard, Vulnerability and Risk in Cuba

In Cuba, the state invests considerable resources in the establishment of preparation plans to mitigate and to minimize the negative impacts of natural threats. As a sample of it, since the year 2010, the country carried out the studies of hazard, vulnerability, and risk (HVR), however, the form in that results of these studies are analyzed present serious limitations for the excessive quantity of data that are dispersed and not very understandable for users belonging to the Centers of Risks’ Management make decisions in an agile way. The present work, exposes the management’s pattern of the studies of Hazard, Vulnerability and Risk in Cuba alongside the occurrence of hydrometeorological extreme events in vulnerable territories; and the structuring process of the computer proposal that modifies and computerizes the current analysis procedure of these studies in the country. As contributions of the research and by means of the use of techniques and tools of Business Intelligence, is designed and implemented, for the case of Santiago de Cuba province, the data warehouse that centralizes the results of the studies for hydrometeorological extreme events in 2011 and 2016. A decision support system (DSS-HVR) is built, and integrated at the developed data warehouse in this work, it allows the analysis of the studies in a holistic manner and from several perspectives, to obtain outstanding and better-represented information through interactive and dynamic reports, both tabulate and graph representation, all as a support for a fast and effective decision making.

Characterization of former athletes with gonarthrotic of Santiago de Cuba province

Gonarthrosis is one of the main causes of pain and disability affecting a large number of the population of former athletes in the provincial Santiago de Cuba. Precisely this research aims to characterize the population of former athletes studied, some qualitative variables of interest, their predominance, and frequency, emphasizing age, sex, sport, and degree of osteoarthritis by the scale of Kellgren and Lawrence; that evaluates the degrees of osteoarthritis observed in x-rays. A percentage of statistical analysis was used for the interpretation of the data. As fundamental results, the group of age intervals of 41 to 50 years with 47% could be observed; the male sex dominated with equal 50% percentile for both age groups of 41 to 50 and 61-60 years; games with balls predominated with 71%; and grade II or mild osteoarthrosis in knees predominated with 71.5%.

Reporte de la Bijirita de Connecticut (Oporornis agilis; Aves: Parulidae) en el oriente de Cuba

La Bijirita de Connecticut (Oporornis agilis) es una especie de ave migratoria neotropical. La literatura y los mapas de distribución publicados por eBird sugieren que la especie utiliza la región del Caribe durante la migración otoñal y primaveral. La isla de Cuba solo posee un reporte de la especie en la cayería norte de Ciego de Ávila y Camagüey. Fue capturado un individuo macho en redes de niebla pertenecientes a la Estación de Anillamiento Permanente Juan Christoph Gundlach, ubicada en la Reserva Ecológica Siboney Juticí, del municipio de Santiago de Cuba, provincia Santiago de Cuba. Este constituye el primer reporte de la especie en la zona oriental de Cuba. La falta de avistamientos de Bijirita de Connecticut en Cuba puede estar condicionada por dos factores principalmente: la baja densidad de individuos en la isla durante la migración o la posible confusión de los ornitólogos cubanos con especies similares.

La interrelación de las agendas mediática y pública en función del desarrollo social. Un estudio transformativo

Desde 2010 el estudio de las agendas sociales en Cuba -y específicamente de las relaciones entre las agendas de los medios y los temas de interés ciudadano-ha develado profundas divergencias respecto a cómo se involucran estos actores para definir la realidad temática. La emisora Radio Titán, del municipio Mella, en la provincia Santiago de Cuba, es pionera en proponerse transformar la situación descrita a partir dela revisión y renovación de su modelo comunicacional y el modelo comunicacional comunitario. Se persigue lograr mecanismos de interrelación dialógica entre su agenda y la de los habitantes de la comunidad, que permita la acción social y el desarrollo participativo a través de la visibilización y diálogo colectivo sobre los problemas comunitarios. El estudio se desarrolla desde 2015 y contó con una etapa diagnóstica previa. Esta disertación presenta reflexiones teóricas, metodológicas y un sistema de acciones culturales para lograr la interrelación dialógica de las agendas. El método utilizado fue la Investigación Acción Participación y lastécnicas de Matriz DAFO y Taller Participativo. Asimismo, se aplicaron los principios del Desarrollo Organizacional y la Planificación Estratégica.

TWO REMARKABLE NEW SPECIES OF PSEUDOCELLUS PLATNICK, 1980 (RICINULEI: RICINOIDIDAE) FROM EASTERN CUBA

Two new species of the American ricinulid genus Pseudocellus Platnick, 1980 are herein described from eastern Cuba: one from a cave in the mountains of northwestern Guantánamo Province and another from a coastal site in southeastern Santiago de Cuba Province. Both species are remarkable by their deep morphological distinction from all other Cuban described congeners, especially those from the same geographical region, e.g., the former possesses very well developed eyespots and the latter has a large retrolateral apophysis in male leg II tibia (also present but much smaller in females). As results, the Cuban ricinulid fauna is now known to comprise 12 nominal species (all congeneric and endemic to the main island), with eight of them (67%) restricted to its eastern region.

Evaluation of the Sustainability Criteria of Forest Management in the Municipality Palma Soriano, Santiago De Cuba Province

The monitoring of the criteria and indicators carried out in Cuba to a municipal level and management areas are limited to a valuation according to the established methodology, making an inadequate evaluation of the same ones, what does not allow to obtain results on scientific bases that guarantee a correct valuation to define if the Forest Management is sustainable. This work carries out an evaluation of the criteria and indicators in the municipality Palma Soriano Santiago de Cuba province. The indicators were valued by means of a scale that allows judging their behavior using the approved and implemented methodology in Cuba. With these valuations there were carried out the graphs of sustainability, as tools to evaluate the performance of the criteria and indicators during 10 years. It concludes that the evaluation of the acting for each criteria was of weak, Excellent, Extremely weak, Weak and Favorable, for the criteria Forest Covering, Health and vitality of the Forest Ecosystems, Contribution of the Forest Ecosystems to the environmental Services, Productive functions of the Forest Ecosystems and Multiple Socio-economic benefits to cover the necessities of the society respectively.
