Introduction: Health care associated infections (HCAIs) are infections that patients get during hospitalization. The most effective prevention of HCAIs is hand washing. Hand washing compliance behavior is still quite low. Nurses' hand washing compliance needs to be improved by optimizing the role of the Infection Prevention and Control Team (PPI team) and adequate hand washing facilities. Research related to the role of the PPI team and existing hand washing facilities still shows mixed results, therefore it is interesting to study.Methods: This study used a descriptive correlational design that aims to determine the relationship between the role of the PPI team and hand washing facilities with nurses' hand washing compliance. The research sample consisted of 204 nurses who were taken at simple random, data collection using questionnaires and observation sheets. The questionnaire consisted of 10 questions for the role of the PPI Team variable and 5 questions for the variable hand washing facilities and 11 statements for observing nurse handwashing compliance.Results: The results showed that nurses who obeyed hand washing were 88% and did not comply with 12%, the role of the PPI team performed well at 97.5% and not good 2.5% and the availability of hand washing facilities were considered good at 97.5% and not good 2,5%. The results of the Chi-Square test showed that there was a significant relationship between the role of the PPI team and nurses' hand washing compliance (P = 0.0001) and there was a significant relationship between the completeness of hand washing facilities and nurses' hand washing compliance (P = 0.007).Conclusion: Based on the results of this study, nurses are expected to be able to maintain and improve hand washing and transform these good habits for other health teams, patients, families, and visitors. In addition, the PPI team must continue to work optimally and the hospital can provide complete hand washing facilities

Published: June 2022

Regarding exploitation and optimizing fisheries resources management in Tomini Bay, the Layang scad fish (Decapterus russelli, Ruppell 1830) is one of the small pelagic fishes inhabiting the bay that still lacks biological information. The species becomes the main target commodity for local fishers as it is commonly consumed as a protein source for coastal communities. This study aimed to determine the length-weight relationships and the growth pattern of Layang fish caught by fishers from Tomini Bay. The samples were collected once per month at Gorontalo City Fish Landing Spot from April to June 2020. Tomini Bay was confirmed as the fishing ground of all the landed fish. Layang is caught by Mini purse seines with a minimum mesh size of ¾ inch. A total of 896 samples of Layang fish were collected randomly from the fishers' catch during their unloading activity at the landing site. Abdomen dissection was performed on all samples for determining the fish’s sex. The fish samples' total length and body weight were measured using a ruler (nearest = 1 mm) and a scale (nearest = 0.01 gram). The result revealed that the length-weight equation of male Layang was W = 0.000004 L3.1972 (R2 = 97.57%), and that of female was W = 0.0000007 L3.0613 (R2 = 98.99%). This result implied a positive allometric growth pattern, excluding the females in April 2020.
Efectos de la estructura textual sobre la comprensión y abstracción de hechos históricos
Authors: Pérez-Almonacid Ricardo , García-Utrera Luis
Published: June 2022

En este trabajo se indagó, desde una aproximación psicológica no representacional, y a partir de dos experimentos, por el efecto de la estructura textual en la comprensión y abstracción de textos. En el primer experimento, quince estudiantes universitarios leyeron tres textos históricos distintos con una de tres estructuras —secuencial, jerárquica o circunstancial—, y se midió si interpretaron, subinterpretaron o sobreinterpretaron los textos en tres pruebas propias de cada estructura, y si realizaban la abstracción de un hecho común a los tres textos. En el segundo, se replicó sistemáticamente el primer experimento, pero con otros quince estudiantes, que se asignaron según su conocimiento conceptual del dominio histórico-político. Los resultados sugieren mayor subinterpretación con la estructura secuencial, y mayor sobreinterpretación con la jerárquica y la circunstancial; el conocimiento conceptual explicó los hallazgos mejor que la estructura textual, pero no dio cuenta de toda la variabilidad. Al final se discuten los resultados en términos de la mediación lingüística como una competencia subordinante tanto del conocimiento conceptual como de la estructura textual. Asimismo, se resaltan las ventajas del registro evolutivo de la comprensión de cada lector, se anticipan algunas fuentes de control adicional para futuros estudios, y se culmina proponiendo algunas implicaciones educativas de los hallazgos.
Modelo explicativo del autocuidado, la regulación emocional y el burnout en psicólogas en condición de aislamiento por COVID-19
Authors: Hernandez Montaño Alicia , González Tovar José
Published: June 2022

Los efectos negativos en la salud mental de la población mundial derivados de la pandemia por coronavirus 2019 (covid-19) han incrementado la demanda de los servicios de atención psicológica. Por ello resulta importante estudiar también el bienestar emocional de este grupo de profesionales. El objetivo de este estudio fue analizar los procesos de autorregulación emocional y autocuidado como factores protectores frente a la presencia del burnout en un grupo de psicólogas mexicanas. Para esto, se utilizó un diseño cuantitativo transversal con alcance explicativo, en una muestra por voluntarios de 226 psicólogas con trabajo clínico. Los datos se recolectaron en formato electrónico, y para su obtención se aplicó la Escala de Conductas de Autocuidado para Psicólogos Clínicos (APC), el Cuestionario de Regulación Emocional (ERQ) y el Inventario Maslach de Burnout (MBI-HS). Para el análisis, se obtuvieron estadísticos descriptivos para cada una de las escalas y subescalas, se estimaron coeficientes de correlación de Pearson, se ajustaron modelos de regresión lineal simple y múltiple para las subescalas del MBI-HS, y se ajustó un modelo de senderos mediante el método GLS. Los resultados indican un bajo nivel de burnout, que se asocia al autocuidado como factor protector frente al agotamiento emocional, a la realización personal, a un mayor uso de la supresión emocional como estrategia de autorregulación, y a la reevaluación cognitiva como factor protector ante la despersonalización. El estudio subraya la importancia fomentar el uso de conductas de autocuidado para disponer del mayor número de psicólogas en las mejores condiciones posibles para hacer frente a los efectos a largo plazo de la pandemia por covid-19.

Published: June 2022

Objectives

Coronavirus disease (COVID-19) can present with various symptoms and can involve multiple organs. Women infected during pregnancy have a higher incidence of obstetrical complications and infants born to “positive” mothers may get the infection with different manifestations. Presepsin seems to be a promising sepsis biomarker in adults and neonates. The aim of this study was to assess if presepsin levels in neonatal cord blood could be influenced by maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Methods

A total of 119 neonates born from women with a confirmed diagnosis of SARS-CoV-2 infection were enrolled and presepsin levels of cord blood samples were collected. All neonates were tested for SARS-CoV-2 infection at birth and after 48–72 h.

Results

The median presepsin value in umbilical cord blood samples collected after birth was 455 pg/mL. Presepsin levels were not influenced by maternal symptoms of COVID-19, weight for gestational age, or delivery mode, and did not significantly differ between infants with and without adverse neonatal outcomes. Infants hospitalized for more than 5 days had a significantly higher presepsin level at birth rather than those discharged up to 4 days of life. Three infants with positive nasopharyngeal swab at birth had higher Presepsin levels than two infants tested positive at 48 h.

Conclusions

This is the first study reporting cord presepsin levels in term and preterm infants born to mothers with COVID-19, that appeared to be not influenced by maternal clinical presentation. However, further studies are needed to explain the mechanisms of P-SEP increase in neonates exposed to perinatal maternal SARS-CoV-2 infection or with an indeterminate/possible SARS-CoV-2 infection in the same neonates.

Acute uterine inversion – A complication revisited; a case series and review of literature
Authors: Kaur Amanjot , Singh Beant
Published: June 2022

Objectives

The objective of this case series is to discuss the various presentations of acute uterine inversion and to discuss how these varied presentations can cause a diagnostic confusion. Differences in acute uterine inversion following a vaginal delivery and a cesarean section are also discussed along with the management of acute uterine inversion, emphasizing the need for a rapid diagnosis and management.

Case presentation

Three such cases of acute uterine inversion – two after vaginal delivery (one second-degree inversion and one third degree inversion) and one during cesarean section have been discussed along with their management.

Conclusions

Uterine inversion is a potentially life-threatening complication which can be prevented by active and careful management of third stage of labor and avoiding cord traction prior to development of the signs of placental separation. Early stages of uterine inversion may be confused with a prolapsed fibroid or a cervical polyp. Prompt management can avert maternal mortality and morbidity.
Extreme fetal macrosomia at 42 gestational weeks: a case report and literature review
Authors: Kummer Julia , Callister Yvonne , Jebens Anja , Mihajlov Valentin , Pech Luisa Maria , Hellmeyer Lars
Published: June 2022

Objectives

Fetal macrosomia is a term to describe excessive fetal birth weight. Fetal macrosomia is strongly associated with adverse obstetrical outcome.

Case presentation

We report a rare case of excessive neonatal weight in a medically unsupervised pregnancy and give a literature review on this significant subject. A 38 year-old woman (Gravida 8 Para 7) presented herself at 42 2/7 weeks of gestation at the labor ward. The pregnancy had not been supervised medically. Labor induction was initiated. Due to failure to progress and suspicion of a disproportion of the fetal head and maternal pelvis an urgent caesarean section was performed. A morbidly macrosomic male infant was delivered (birth weight: 6,760 g [>99. percentile], length: 60 cm [>99. percentile]).

Conclusions

The morbidity for infants and women increases with a birth weight exceeding 4,500 g. Gestational diabetes mellitus, a high pre-pregnancy body mass index and excessive gestational weight gain have been independently associated as risk factors. The increase in pregnancies complicated by maternal obesity and gestational diabetes emphasizes the necessity of evidence-based clinical interventions to prevent or reduce these diseases. If prenatal care is not frequented by mothers-to-be there are no options open for obstetricians to detect fetal macrosomia and to intervene.
Physiological pulmonary assessments in the management of bilateral diaphragmatic eventration
Authors: Arattu Thodika Fahad , Williams Emma E. , Dassios Theodore , Adu John , Nanjundappa Mahesh , Harris Christopher , Greenough Anne
Published: June 2022

Objectives

To describe the importance of comprehensive assessment to determine the underlying diagnosis and the role of physiological pulmonary measurements in the management of congenital bilateral eventration of the diaphragm.

Case presentation

A female infant born at 34 weeks gestation required intubation and ventilation at birth. Chest radiographical imaging revealed bilateral density to the bases of both lung fields with raised hemi-diaphragms. Ultrasound imaging showed focal diaphragmatic eventration with bulging of the dome of the liver into the right and left hemithoraces. Assessment of the electrical activity of the diaphragm during a spontaneous breathing trial demonstrated a mean amplitude consistent with that of ventilated infants of the same gestational age with intact diaphragms. Hence she was extubated which was successful. Chest radiographic thoracic area measured post extubation was 1,654 mm2, equivalent to that of a term infant with severe congenital diaphragmatic hernia. As the electrical activity of the diaphragm was normal this suggests replacement of the diaphragmatic muscle tissue with fibrous bands was likely to be only partial, and hence why extubation was successful. She had other abnormalities presenting in the neonatal period including dermal melancytosis, central hypotonia, hyperinsulinism and poor feeding. The infant underwent extensive investigation which revealed a KMT2D gene mutation associated with Kabuki syndrome.

Conclusions

Physiological pulmonary measurements may add clinical management in bilateratal diaphragmatic eventration.

Authors: Fankhouser Russell W. , Murrell Derek E. , Anane Yaa Y. , Hurley David L. , Mamudu Hadii M. , Harirforoosh Sam
Published: June 2022

Objectives

This study sought to identify potential pharmacogenetic associations of selected enzymes and transporters with type 2 diabetes (T2D). In addition, pharmacogenomic profiles, concentrations of asymmetric dimethylarginine (ADMA) or kidney injury molecule-1 (KIM-1), and several covariates were investigated.

Methods

Whole blood was collected from 63 patients, with 32 individuals with T2D. A pharmacogenomic panel was used to assay genetic profiles, and biomarker ELISAs were run to determine subject concentrations of ADMA and KIM-1. Additive genetic modeling with multiple linear and logistic regressions were performed to discover potential SNPs-outcome associations using PLINK.

Results

Ten SNPs were found to be significant (p<0.05) depending on the inclusion or exclusion of covariates. Of these, four were found in association with the presence of T2D, rs2231142, rs1801280, rs1799929, and rs1801265 depending on covariate inclusion or exclusion. Regarding ADMA, one SNP was found to be significant without covariates, rs1048943. Five SNPs were identified in association with KIM-1 and T2D in the presence of covariates, rs12208357, rs34059508, rs1058930, rs1902023, and rs3745274. Biomarker concentrations were not significantly different in the presence of T2D.

Conclusions

This exploratory study found several SNPs related to T2D; further research is required to validate and understand these relationships.
Hydrodesulfurization of 4,6–Dimethyldibenzothiophene on NiMoP/γ–Al2O3 catalyst under reactive distillation conditions in a micro trickle bed reactor: solvent and temperature effect
Authors: García-Martínez Julio Cesar , Chávez-Esquivel Gerardo , Colín-Luna José Antonio , de los Reyes-Heredia José Antonio
Published: June 2022

In this work, the influence of pressure and temperature experimentally applied on reactive distillation (RD) under lower conditions than conventional hydrotreating (HDT) processes, the hydrodesulfurization (HDS) reaction of 4,6–dimethyldibenzothiophene (4,6–DMDBT) molecule and the experimental performance of a down-flow micro trickle bed reactor (micro-TBR) with n–dodecane and decalin were studied. Thermodynamic analyses to evaluate hydrogen solubility in liquid hydrocarbons and evaporation for n–dodecane and decalin as lineal and cyclic representative solvents, respectively, were considered. It was possible to define experimental conditions, producing a small deviation of the plug flow model (PFM) and diminished the gas–liquid (G–L) mass transfer limitation as determined from a reactor model at 2.5 MPa. The axial dispersion model (ADM) and PFM models adjust the experimental data at 2.5 MPa operational pressure and the 4,6–DMDBT conversion obtained was ca. 20–50% using n–dodecane; 1.5 times higher when decalin was using. This behavior was due to the liquid hydrogen fraction of n–dodecane was two times higher than for decalin for all operational pressures. In this sense, the use of n–dodecane as a solvent decreased the mass transfer resistance at the G–L and liquid–solid (L–S) interphases. The internal mass transfer resistance in the G–L interphase not only depends on the diffusivity of the solvent, but it also depends on both, the temperature and hydrogen pressure, finding that the RD conditions with n–dodecane are viable in the treatment of sterically impaired molecules in HDS processes.

q
(Ω). Therefore we can apply the theory of nonlinear semigroups in Banach spaces in order to get regularity results in time and space.

The second part of the paper deals with the numerical solution of the problem. It is dedicated to the application of the space-time discontinuous Galerkin method (STDGM). It means that both in space as well as in time discontinuous piecewise polynomial approximations of the solution are used. We concentrate to the theoretical analysis of the error estimation.
Updating risk model for SGTR accident based on success criteria analysis
Authors: Mohammadnia Meisam , Hoseyni Seyed Mohsen , Karimi Kaveh
Published: June 2022

Success criteria analysis plays a key role in the development of realistic probabilistic safety/risk assessment (PSA/PRA) model because it provides supporting information regarding the response of complex nuclear power plant systems to different accident conditions. The current paper performs plant specific success criteria analysis for steam generator tube rupture (SGTR) accident in a typical pressurized water reactor (PWR) and demonstrates implementation of the obtained best estimate results on a risk model which has been initially developed based on expert judgment and general plant design data. The modifications on the risk model include configuration of the safety systems as well as the event tree structure. The updated PSA model shows 50% reduction in the plant core damage frequency (CDF) in comparison to the base case risk model. This highlights the importance of success criteria analysis for the development of a realistic PSA model in risk informed applications.

In order to solve the difficulties caused by the gradient term, we introduce some new techniques which may also be applied to investigate the qualitative properties of solutions for many problems with gradient terms. Our results are extensions of Berestycki and Nirenberg [Monotonicity, symmetry and antisymmetry of solutions of semilinear elliptic equations, J. Geom.

Smear character recognition method of side-end power meter based on PCA image enhancement
Authors: Luo Peng , Hu Xuekai , Zhao Yuhao , Jiang Yi , Lu Fanglin , Liang Jifeng , Xu Liang
Published: June 2022

Since it is difficult for manual recording to track the rapid change of indication of the power meter, the power meter images are collected by the camera and automatically recognized and recorded to effectively overcome the disadvantages of manual recording. However, the complex scene lighting environment and smearing character shadows make it difficult to transfer captured images directly to convolutional neural networks for character recognition. A smear character recognition method of side-end power meter under complex lighting conditions is proposed in this article. First, the uneven illumination image enhancement algorithm is studied. Through the estimation of the illumination component of the image, the fusion weight is calculated by the principal component analysis for multiscale fusion, and the up-sampling and down-sampling are adopted to reduce the calculation of the algorithm and achieve the rapid image enhancement. A convolution neural network framework based on deep learning is proposed to realize the segmentation of smear characters, and the final segmented individual characters are fed into a network to identify the meter readings. The experimental results show that the proposed smear character recognition method has fast recognition speed, and the recognition rate of samples with the smear character and complex illumination reaches 99.8%, which meets the requirements of power meter character recognition and is better than other algorithms.

Authors: Yao Chengli , Ding Aimin , Li Hongying , Wei Yanxin
Published: June 2022

The traditional measurement methods of luminescent materials have some problems, such as low accuracy and large amount of calculation. Therefore, a new measurement method is proposed in this article. Taking molecular capture as the core, the molecular force field is established. According to the first law of hohber_Kong’s molecules captures molecular dynamics, it extracts dynamic simulation data information and takes this as the input to establish the Markov data analysis model. The molecular dynamics data were input, and the multi-index method was used to describe the characteristics of metal complex luminescent materials. According to the external shape of the material and the tightness of molecular blocks, the dynamic observation index of the current complex can be obtained to determine the characteristics of luminescent materials. The experimental data show that the method in this article has higher accuracy, lower amount of calculation and good overall error adjustment effect. It can effectively determine the characteristics of complex luminescent materials.

Published: June 2022

The present study was developed to reinforce a thermoplastic matrix with carbonaceous material to improve its thermal and mechanical properties. Composite materials formed from the homogenization of polylactic acid (PLA) and reduced graphitic oxide (RGO) were synthesized and characterized, reinforcement of the polymer’s thermomechanical properties and the adequate homogeneity ratio in the dispersion of the composite material were studied. Graphitic oxide (GO) was synthesized by the modified Hummers method, followed by thermal exfoliation. The chemical composition and the structure of RGO were studied by infrared (FT-IR) and Raman spectroscopies, respectively. PLA composites with different RGO contents (2 and 3% by weight) were prepared and compared in terms of distribution of RGO in the matrix and morphology, using scanning electron microscopy. The thermal stability of the composites was determined through thermogravimetric analysis. Torque of the different composites was measured, which increased at 21%; the tensile test showed an improvement in the mechanical parameters of the composites because the RGO favors the rigidity of the composite. In addition, the oxygenated functional groups present in the RGO allowed a more significant interaction with the PLA matrix, which results in an effective reinforcement of the mechanical properties of the composite material.

PERANAN AGEN SOSIALISASI IBU BAPA TERHADAP PENGETAHUAN POLITIK MAHASISWA MELAYU DI UNIVERSITI AWAM
Authors: Mazli Mamat  , Ramli Rahimi
Published: June 2022

Abstract - The voting age restriction has been lowered to 18 years old, and the removal of Section 15(2)(c) of the AUKU has made it the country's responsibility to prepare young people to become mature voters. Some of these groups are made up of university students. The socialization process of students who are knowledgeable as voters in elections is closely tied to their socialization process. As a result, the purpose of this study is to analyze students' political knowledge levels as well as the role of parents as the earliest and most organized political socialization agents in influencing students' political knowledge. Malay students from four public universities in the Klang Valley were asked to participate in this study. The research uses a quantitative approach, and the information was gathered through questionnaires collected during a field survey. The study's sample included 441 Malay students who were chosen using stratified and simple sampling methods. The study's findings revealed that, despite their high level of political knowledge, the students' political information was not received directly from their parents' agents. As a result, these students learned knowledge from other socialization agents, particularly in relation to politics, but the values and beliefs that parents socialize remain their consideration and reference, as parents are more stable socialization agents than other socialization agents.

Mass effect from a goiter is a serious complication with potentially life-threatening consequences. In rare instances, a goiter can compress nearby vessels, compromising cerebral blood flow, which can lead to an ischemic stroke. Ischemic strokes generally occur due to atherogenic or embolic phenomenon, albeit a rare etiology can be due to a mechanical obstruction of great vessels of the neck that provide blood supply to the brain. An unusual example of a similar obstruction is the mass effect of an expansive goiter on the carotid artery (CA) in the neck. We present a rare case of a 90-year-old female who had a historically untreated goiter for 13 years. She presented with symptoms of acute stroke, including right-sided weakness and dysarthria. CT angiogram of the neck revealed a massively enlarged thyroid gland causing compression and intermittent obstruction of the blood flow in the left common CA. Subsequently, the patient underwent a total thyroidectomy. Postoperatively, she had a remarkable recovery of her symptoms of right-sided weakness and dysarthria. Acknowledging stroke as a grave mechanical complication of a large multinodular goiter is crucial for timely and appropriate management to avoid serious consequences.

Learning points

The natural history of euthyroid multinodular goiters include abnormal enlargement of the thyroid gland, which results in local compression of structures in the neck causing neurovascular injury.

Timely diagnosis and surgical management of an enlarging goiter compressing the CA can reduce morbidity from an ischemic stroke.

Ischemic stroke is a rare and dangerous complication of a giant multinodular goiter.

El estudio se realizó de febrero a junio del 2016, en la región Huetar Norte de Costa Rica. El objetivo fue mostrar resultados generales de la situación productiva y socioeconómica de los sistemas de producción caprina de la región. Se utilizó la base de datos del VI Censo Nacional Agropecuario (CENAGRO 2014) y una herramienta (encuesta) aplicada a socios activos de Coopecaprina R.L. Se utilizaron 15 variables (11 cualitativas y 4 cuantitativas). Se determinó mediante estadística descriptiva (por medio del software estadístico PSPPIRE (PSPP+GUI)), la distribución absoluta y porcentual para variables cualitativas, y los resultados de tendencia central y dispersión, para variables cuantitativas. En general, el 52 % de los suetos asociados a Coopecaprina R.L., posee entre 1 a 40 animales en sistemas estabulados y destinan su producción al mercado local y la venta en finca. El 50 % de estos sistemas son liderados por hombres con escolaridad primaria y trabajan internamente en la finca. En la región Huetar Norte, el 94 % de las fincas posee menos de 20 animales y se mantienen en sistemas de pastoreo basados en pasturas naturales, y destinan la producción a la venta en finca. El 54 % de estos sistemas son dirigidos por hombres que poseen primaria, no se asocian en organizaciones y laboran sin pago en sus fincas.

Un factor clave en la producción de almácigos es garantizar un sustrato que cumpla con los requisitos de textura, estructura, fertilidad y una buena sanidad, a fin de conseguir plantas sanas, vigorosas y con buen desarrollo para la etapa de campo. Una práctica para obtener almácigos a menor costo y con ciertas características es la técnica de almácigo en tubete. El objetivo de este estudio fue evaluar variables de crecimiento, costo económico y mortalidad de un almácigo de café producido mediante tubetes en tres diferentes sustratos. El ensayo se llevó a cabo en la localidad de El Cerro, Sabanilla de Alajuela, durante los meses de abril a septiembre del 2015. Se utilizó un diseño de bloques completos al azar con cinco repeticiones y tres tratamientos (T), que correspondieron a los sustratos T1: Peat Moss, T2: suelo + broza de café y T3: suelo + súper tierra + fibra de coco. En cuanto a los costos de producción aunque hubo diferencias entre cada sustrato, cada uno estuvo por debajo del precio normal de una plántula producida en el Valle Central. Las variables de crecimiento analizadas (altura, diámetro del tallo y pares de hojas) presentaron diferencias significativas mediante la prueba estadística LSD Fisher (>0.05); para todas, el comportamiento fue T1 > T2 > T3. No hubo pérdidas en plantas para los tres tratamientos, por lo que el porcentaje de mortalidad se mantuvo en cero. No se determinó ninguna diferencia en cuanto a los sustratos, así que cualquiera de ellos puede ser empleado para la elaboración de almácigos tanto por los materiales usados como por el costo de elaboración, el cual en todos los casos es menor al precio promedio de elaboración con otras técnicas. La decisión de cuál de ellos utilizar dependerá del criterio y la capacidad del productor.

En los últimos años, el movimiento OVOP ha crecido notablemente en Costa Rica como resultado de una iniciativa de instituciones del sector público en colaboración con organismos internacionales de cooperación. Su la finalidad es promover el desarrollo económico y la identidad local, mediante la generación y encadenamiento de capacidades comunitarias, emprendedoras y empresariales sustentadas en el potencial de los recursos locales. El éxito de una estrategia OVOP requiere disponer de información sistematizada de la oferta de productos y servicios disponibles en la comunidad, como base para la toma de decisiones y para la gestión de los procesos de organización comunitaria y empresarial local. Debido a que el Cantón de Dota, uno de los territorios OVOP de Costa Rica, no disponía de información con el grado de sistematización necesaria, se realizó un diagnóstico para la caracterización de emprendimientos en los principales distritos del cantón. La información fue recolectada mediante fuente primaria, específicamente aplicación de encuestas, llamadas telefónicas y fuente secundaria (bases de datos de la Municipalidad de Dota). El estudio se realizó durante el periodo de 2018 a 2020. Los resultados mostraron que la mayor cantidad de emprendimientos se agrupan en la categoría de producción alimentaria, seguida de las categorías de artesanías y hospedaje. Se aplicó un análisis de frecuencia de las empresas por distrito, en el cual se determinó que Santa María es el que presenta la mayor concentración de emprendimientos.

Rhabdomyolysis is a syndrome caused by destruction and necrosis of muscle tissue, which is accompanied by the release of intracellular contents into the systemic circulation. The etiology of rhabdomyolysis is multifaceted, however, regardless of the etiological factor, the central element of its pathophysiology is systemic endotoxemia with multiple organ failure syndrome. Acute renal failure is one of the most common manifestations of organ dysfunction. Considering the pathogenetic model of the development of systemic endotoxemia, the timely use of extracorporeal therapy, which reduces mortality in organ failure, seems promising. All the current types of extracorporeal therapy can be divided into convection (hemofiltration), diffusion (hemodialysis), convection/diffusion (hemodiafiltration), sorption (hemoperfusion) and plasma exchange (plasmapheresis, plasma exchange, plasma sorption, etc.) methods based on physical principle.

The aim of the reviewwas to summarize the available clinical data on extracorporeal treatments for rhabdomyolysis and to assess the feasibility and best indications for these methods based on the current pathogenetic model of rhabdomyolysis.

Material and methods.The search for information was carried out in the Web of Science, Scopus, Medline, PubMed, RSCI, E-library and other databases. Eighty-one sources were identified containing current therapeutic approaches and relevant data of clinical and scientific research on the subject of this review.

Results.In this review, the main etiological, epidemiological and pathogenetic models of acute renal injury in rhabdomyolysis have been discussed. The main methods of extracorporeal therapy have been reviewed and evaluated based on current understanding, and latest clinical data on their effectiveness have been summarized.

Conclusion.The choice of the optimal extracorporeal treatment method, the time of initiation and duration of the procedure still remain controversial. The solution to this issue can potentially help to better correct the electrolyte disturbances and could protect against organ dysfunction, which would improve the outcome in patients with rhabdomyolysis.

Analysis of morphology, stratigraphic and geographic distribution of the group of nautilid species, mainly from the Westphalian of Western Europe, and the Bashkirian and Moscovian of the Donets Basin (Eastern Ukraine) made it possible to establish a new genus Pseudogzheloceras Dernov, gen. nov. This genus includes tainoceratids with an evolute discoidal conch. The umbilical perforation is present. Cross section of the adult whorls is sub-square or almost rectangular. Surface ornamentation is represented by large transverse ribs on the flanks. Siphuncle is sub-central or is situated between the venter and the centre of the whorl (the position of the siphuncle is not known for the most species). Suture line has ventral, lateral and dorsal lobes; sometimes a lobe or saddle is present on the umbilical area. The new genus differs from the genus Gzheloceras by the sub-square or almost rectangular whorls cross section and coarser surface ornamentation. Pseudogzheloceras Dernov, gen. nov. is distinguished from the genus Parametacoceras Miller et Owen, 1934 (Pennsylvanian of North America, Westphalian of Western Europe, Moscovian of the Donets Basin and Moscow Syneclise) by the presence of transverse ribs on the flanks of the body chamber. The new genus includes the following species: Pseudogzheloceras costatum (Hind, 1905) comb. nov., Ps. falcatum (Sowerby in Prestwich, 1840) comb. nov., Ps. rotifer (Salter, 1864) comb. nov., Ps. postcostatum (Bisat, 1930) comb. nov., Ps. donetzense (Kruglov in Librovitch, 1939) comb. nov., Ps. orthocostatum (Kruglov in Librovitch, 1939) comb. nov., Ps. tacitum (Shimansky, 1957) comb. nov., and, possibly, Ps. maklai (Shimansky, 1967) comb. nov. These species had previously belonged to the genera Pleuronautilus, Metacoceras, Huanghoceras, and Gzheloceras. The new genus is known from the Westphalian of Western Europe and North Africa, Pennsylvanian of the Donets Basin and Moscow Syneclise, and possibly the Upper Pennsylvanian of the Fergana Depression. The research results have a great importance for studying the relationships between nautilid faunas of Carboniferous palaeobasins, as well as clarifying the taxonomy and phylogeny of non-ammonoid Carboniferous cephalopods.
