Abstract Given the scarcity of water resources for agricultural use, it is necessary to promote the use of wastewater for agriculture. The towns of Capulálpam de Méndez and Ixtlán de Juárez in the State of Oaxaca have anaerobic wastewater treatment plants (WWTP). The morphological growth, biomass production and N and P content were evaluated in two forage species -Chenopodium quinoa Willd and Zea mays- irrigated with treated wastewater (TWW). A complete randomized design (CRD) was established in each municipality, given the homogeneity of the soil, using a 2 x 2 factorial arrangement, i.e., two forage crops (Quinoa and corn) and two types of irrigation (fresh water and treated wastewater), with 4 replicates per treatment. Analyses of variance and Tukey mean tests (P≤0.05) were performed for the studied variables. In the soils, the pH level was "moderately acid" to "neutral" (5.1 to 7.3); the EC indicated "negligible effects of salinity"; organic matter was found at intervals of "medium to high", and the texture was sandy clay loam in Ixtlán and clay loam in Capulálpam. Growth variables (plant height, stem diameter, and number of leaves) and biomass were significantly higher in plants irrigated with treated wastewater in both forage crops. Nitrogen and phosphorus contents were significantly higher in quinoa and corn plants receiving TWW. TWW could be an alternative that would help reduce the use of chemical fertilizers, as it is an important source of nutrients in forage crops.

Resumen Ante la escasez del recurso hídrico para el uso agrícola, es necesario promover el uso del agua residual para la agricultura. En las localidades Capulálpam de Méndez e Ixtlán de Juárez, Estado de Oaxaca cuentan con plantas de tratamiento de aguas residuales (PTAR) de tipo anaerobio. Se evaluó el crecimiento morfológico, producción de biomasa y contenido de N y P en dos especies forrajeras: Chenopodium quinoa Willd y Zea mays, regados con agua residual tratada (ART). Se estableció un diseño completo aleatorio (DCA) en cada municipio, dada la homogeneidad del suelo. Con arreglo factorial 2 x 2, esto es, dos cultivos forrajeros (Quinoa y maíz), y dos tipos de riego (agua dulce y agua residual tratada), con 4 repeticiones por tratamiento. Se realizaron análisis de varianza y pruebas de media Tukey (P≤0.05) de las variables estudiadas. En los suelos el nivel de pH fue “moderadamente acido” a “neutro” (5.1 a 7.3); la CE indicó “Efectos despreciables de la salinidad”; Materia orgánica en intervalos de “medio a alto”; y Textura Franco arcilloso arenoso en Ixtlán y Franco arcilloso en Capulálpam. Las variables de crecimiento (altura de planta, diámetro de tallo y número de hojas) y biomasa fueron significativamente mayores en plantas regadas con agua residual tratada en ambos cultivos forrajeros. El contenido de nitrógeno y fósforo fue significativamente mayor en plantas de quinoa y maíz que recibieron ART. El ART podría ser una alternativa que ayude a disminuir el uso de fertilizantes químicos, al ser una fuente importante de nutrimentos en los cultivos forrajeros.

Abstract Introduction: The central venous catheter is necessary in pediatric care; however, it is an important cause of nosocomial bacteremia, with 25% mortality. The nursing professional is responsible for the maintenance of the central venous catheter, in order to prevent local and systemic complications such as endocarditis and bacteremia related to intravenous treatment. Objective: To describe the nursing interventions for the maintenance of the central venous catheter in pediatric patients of a specialized hospital. Methodology: Observational, descriptive, cross-sectional design, sample made up of 85 nursing professionals who provided direct care to hospitalized children and received training, non-probabilistic sampling; the instrument used was a central venous catheter maintenance checklist, and data were collected with the observation technique. The survey complies with the ethical aspects of the general health law on research. Results: Nursing interventions were performed with an overall compliance of 90.1%; it is emphasized that 70.6% washed their hands before handling the device. Cleaning and maintenance of the insertion site was carried out by 98.8%, ports and connections were disinfected, and 92.9% lumens were identified. Conclusion: Nursing professionals performed interventions for the maintenance of the central venous catheter with a good compliance. However, the interventions with lower compliance that require improvement are hand hygiene, times for changing equipment and solutions, disinfection of ports and connections, which are essential to reduce infections in the bloodstream. In addition to future surveys about the professional and institutional factors associated with compliance.

ABSTRACT Objective: To investigate the impact of delirium severity in critically ill COVID-19 patients and its association with outcomes. Methods: This prospective cohort study was performed in two tertiary intensive care units in Rio de Janeiro, Brazil. COVID-19 patients were evaluated daily during the first 7 days of intensive care unit stay using the Richmond Agitation Sedation Scale, Confusion Assessment Method for Intensive Care Unit (CAM-ICU) and Confusion Method Assessment for Intensive Care Unit-7 (CAM-ICU-7). Delirium severity was correlated with outcomes and one-year mortality. Results: Among the 277 COVID-19 patients included, delirium occurred in 101 (36.5%) during the first 7 days of intensive care unit stay, and it was associated with a higher length of intensive care unit stay in days (IQR 13 [7 - 25] versus 6 [4 - 12]; p < 0.001), higher hospital mortality (25.74% versus 5.11%; p < 0.001) and additional higher one-year mortality (5.3% versus 0.6%, p < 0.001). Delirium was classified by CAM-ICU-7 in terms of severity, and higher scores were associated with higher in-hospital mortality (17.86% versus 34.38% versus 38.46%, 95%CI, p value < 0.001). Severe delirium was associated with a higher risk of progression to coma (OR 7.1; 95%CI 1.9 - 31.0; p = 0.005) and to mechanical ventilation (OR 11.09; 95%CI 2.8 - 58.5; p = 0.002) in the multivariate analysis, adjusted by severity and frailty. Conclusion: In patients admitted with COVID-19 in the intensive care unit, delirium was an independent risk factor for the worst prognosis, including mortality. The delirium severity assessed by the CAM-ICU-7 during the first week in the intensive care unit was associated with poor outcomes, including progression to coma and to mechanical ventilation.

RESUMO Objetivo: Investigar como a gravidade do delirium afeta pacientes graves com COVID-19 e sua associação com os desfechos. Métodos: Estudo de coorte prospectivo realizado em duas unidades de terapia intensiva terciárias no Rio de Janeiro (RJ). Os pacientes com COVID-19 foram avaliados diariamente durante os primeiros 7 dias de internação na unidade de terapia intensiva usando a escala de agitação e sedação de Richmond, a Confusion Assessment Method for Intensive Care Unit (CAM-ICU) e a Confusion Assessment Method for Intensive Care Unit-7 (CAM-ICU-7). A gravidade do delirium foi correlacionada com os desfechos e a mortalidade em 1 ano. Resultados: Entre os 277 pacientes com COVID-19 incluídos, o delirium ocorreu em 101 (36,5%) durante os primeiros 7 dias de internação na unidade de terapia intensiva e foi associado a maior tempo de internação na unidade de terapia intensiva em dias (IQ: 13 [7 - 25] versus 6 [4 - 12]; p < 0,001), maior mortalidade hospitalar (25,74% versus 5,11%; p < 0,001) e maior mortalidade em 1 ano (5,3% versus 0,6%, p < 0,001). O delirium foi classificado pela CAM-ICU-7 em termos de gravidade, e escores maiores foram associados à maior mortalidade hospitalar (17,86% versus 34,38% versus 38,46%, IC95%, valor de p < 0,001). O delirium grave foi associado a um risco maior de progressão ao coma (RC de 7,1; IC95% 1,9 - 31,0; p = 0,005) e à ventilação mecânica (RC de 11,09; IC95% 2,8 - 58,5; p = 0,002) na análise multivariada, ajustada por gravidade e fragilidade Conclusão: Em pacientes internados com COVID-19 na unidade de terapia intensiva, o delirium foi fator de risco independente para o pior prognóstico, incluindo mortalidade. A gravidade do delirium avaliada pela CAM-ICU-7 durante a primeira semana na unidade de terapia intensiva foi associada a desfechos desfavoráveis, incluindo a progressão ao coma e à ventilação mecânica.

Resumen El cruzamiento permite aprovechar las diferencias genéticas aditivas entre razas, también permiten hacer uso de la heterosis y de la complementariedad. Por lo tanto, se necesita generar información de la eficacia de las cruzas en comparación con las razas puras, bajo las condiciones de interés. El objetivo fue cuantificar el impacto de los efectos genéticos aditivos y no aditivo para días a primer estro (DPE), días a primer servicio (DPS), días abiertos (DA), servicios por concepción (SPC), intervalo entre partos (IP) y duración de la gestación (DG). Se utilizó la información productiva y genealógica de hembras provenientes de un dialelo entre Holstein (HO) y Suizo Pardo (SP), un total de 148 vacas de las razas HO (n=43), SP (n=64) y sus cruzas reciprocas HO-SP (n=20) y SP-HO (n=21). Se utilizaron contrastes para estimar la heterosis individual y las diferencias entre los efectos genéticos directos y entre los efectos genéticos maternos con base en los modelos de Dickerson. Los resultados mostraron que la heterosis y las diferencias entre los efectos maternos no fueron significativos (P>0.05) para ninguna de las características estudiadas. Las diferencias entre efectos genéticos directos solo fueron importantes (P<0.05) para SPC y DG. En conclusión, la heterosis generada por el cruzamiento entre HO y SP no influyó sobre la eficiencia reproductiva de las hembras. Los efectos maternos no fueron diferentes entre HO y SP. Los efectos genéticos directos para SPC y DG favorecieron a la raza SP.

Abstract Crossbreeding allows taking advantage of additive genetic differences between breeds, they also allow making use of heterosis and complementarity. Therefore, it is necessary to generate information on the efficacy of crosses compared to pure breeds under the conditions of interest. The objective was to quantify the impact of additive and non-additive genetic effects for days to first estrus (DFE), days to first service (DFS), days open (DO), services per conception (SPC), calving interval (CI) and gestation length (GL). The productive and genealogical information of females from a diallel between Holstein (HO) and Brown Swiss (BS), a total of 148 cows of the breeds HO (n=43), BS (n=64) and their reciprocal crosses HO-BS (n=20) and BS-HO (n=21), was used. Contrasts were used to estimate individual heterosis and differences between direct genetic effects and between maternal genetic effects based on Dickerson models. The results showed that heterosis and differences between maternal effects were not significant (P>0.05) for any of the traits studied. Differences between direct genetic effects were only important (P<0.05) for SPC and GL. In conclusion, the heterosis generated by the crossbreeding between HO and BS did not influence the reproductive efficiency of females. Maternal effects were not different between HO and BS. Direct genetic effects for SPC and GL favored the BS breed.

Resumen. El Síndrome Respiratorio y Reproductivo del Cerdo (PRRS) es una enfermedad endémica en porcinos que tiende a la cronicidad. Los esfuerzos se centran en prevención y control para minimizar el daño, pues no existe tratamiento. Se evaluó el efecto de la adición de ácido docosahexaenoico (DHA) y oleorresina de cúrcuma y capsicum (EP, extractos de plantas) en la alimentación de cerdas reproductoras afectadas con PRRS sobre su desempeño productivo, de salud y en su progenie. Cuarenta y ocho cerdas de primer parto se distribuyeron al azar en cuatro tratamientos (Tr1, testigo; Tr2, DHA; Tr3, EP; Tr4, DHA+EP). El ensayo con el segundo parto siguió el mismo diseño. Tr3 y Tr4 obtuvieron más peso de lechones al nacer en ambos partos (P < 0.05) que los demás. En ambos partos, la adición de DHA y EP resultó en menos cantidad de momias (P < 0.05) y menor costo que los otros tratamientos. Tr3 tuvo mayor número de lechones vivos en ambos partos, mientras que Tr4 solo en el segundo parto (P < 0.05). En el primer parto, se destetaron más lechones en Tr2 y Tr3 (P > 0.05); pero Tr2 superó a los demás en el segundo parto (P > 0.05). Por ELISA, todos los cerdos desarrollaron anticuerpos contra PRRS. Los grupos que recibieron DHA y/o EP tuvieron concentraciones séricas de IgG superiores al testigo (P < 0.05). Se concluye que la adición de DHA y EP mejora la respuesta productiva y mayores concentraciones de IgG en ambos partos, además de reducir el costo de producción de las cerdas.

Abstract. Pig Respiratory and Reproductive Syndrome (PRRS) is an endemic disease in pigs that tends to become chronic. Efforts are focused on prevention and control to minimize damage, as no treatment exists. The effect of adding docosahexaenoic acid (DHA) and turmeric oleoresin and capsicum (plant extracts, PE) in the feeding of breeding sows affected with PRRS on their productive performance, health and progeny was evaluated. Forty-eight first-parturition shows were randomly distributed into four treatments (Tr1, control; Tr2, DHA; Tr3, PE; Tr4, DHA+PE). The second parturition assay followed the same design. Tr3 and Tr4 got more piglet weight at birth in both parturitions (P < 0.05) than the others. In both deliveries, the addition of DHA and PE resulted in fewer mummies (P < 0.05) and lower cost than the other treatments. Tr3 had a higher number of live piglets in both parturitions, while Tr4 only got that in the second parturition (P < 0.05). More piglets were weaned in Tr2 and Tr3 (P > 0.05) in the first parturition; but Tr2 outperformed the others in the second parturition (P > 0.05). By ELISA, all pigs developed antibodies against PRRS. The groups receiving DHA and/or PE had higher serum IgG concentrations than control (P < 0.05). It is concluded that the addition of DHA and PE improves the productive response and induced higher concentrations of IgG in both parturitions, in addition to reducing the production cost of sows.

Resumo O presente estudo objetivou analisar a percepção da qualidade de vida (QV) dos acadêmicos de uma instituição promotora da saúde, por seriação, verificando o efeito que a experiência ao longo das séries exerce sobre a QV. Delineou-se um estudo de caso transversal, com amostra representativa de 390 universitários da instituição. Para avaliação da QV foi utilizado o instrumento WHOQOL-bref (OMS), juntamente com o questionário sociodemográfico. Os dados foram analisados com estatística descritiva e analítica, utilizando o IBM SPSS Statistics. Os resultados mostraram que o 1º ano da graduação apresentou o maior percentual de alunos que precisavam melhorar a QV e, conforme o avanço da seriação, aumentou gradualmente a percepção positiva da qualidade de vida, com índices estatisticamente significantes entre o 1º e 3º ano (p = 0,044) e 1º e 4º ano (p = 0,010). Verificou-se que, à medida em que o estudante progrediu na seriação, tendo mais tempo de vivência na instituição, ocorreu uma tendência ao aumento dos escores médios da qualidade de vida. Conclui-se que o ambiente universitário, quando promotor da saúde, pode contribuir positivamente para a melhoria da qualidade de vida dos estudantes.

Abstract The present study aimed to analyze the perception of quality of life (QOL) of students at a health-promoting institution, by grade, verifying the effect that experience throughout the grade has on QOL. A cross-sectional case study was designed, with a representative sample of 390 university students from the institution. To assess QoL, the WHOQOL-bref (OMS) instrument was used, together with the sociodemographic questionnaire. Data were analyzed with descriptive and analytical statistics using IBM SPSS Statistics. The results showed that the 1st year of graduation had the highest percentage of students who improved their QOL and, as the series progressed, the positive perception of quality of life gradually increased, with statistically significant rates between the 1st and 3rd year. (p = 0.044) and 1st and 4th year (p = 0.010). It was found that, as the student advanced in grade, having spent more time at the institution, there was a tendency for the average quality of life to increase. It is concluded that the university environment, by promoting health, can contribute positively to improving the quality of life of students.

ABSTRACT Thyroid cancer is a rare condition in the pediatric population, it has a unique set of clinical, pathological and molecular characteristics in children. The typical presentation is an asymptomatic thyroid nodule of months of evolution, as in the described case. Compared with adults, children more often present with late-stage aggressive disease. The management and treatment approach is radical thyroid surgery and extensive lymph node dissection, then iodotherapy and thyroid replacement. Survival is excellent, at 10 years it is greater than 98%, however, complications related to lifelong treatment, which are not uncommon, should be kept in mind.

RESUMEN El cáncer de tiroides es una entidad infrecuente en población pediátrica, tiene un conjunto único de características clínicas, patológicas y moleculares en niños. La clínica típica es un nódulo tiroideo de meses de evolución asintomático, como en el caso descrito. En comparación con los adultos, los niños presentan con mayor frecuencia una enfermedad agresiva en etapa avanzada. La conducta de manejo y tratamiento es la cirugía de tiroides radical y el vaciamiento ganglionar amplio, luego yodoterapía y suplencia tiroidea. La supervivencia es excelente, a los 10 años es mayor a 98% sin embargo, se deben recordar las complicaciones relacionadas con el tratamiento de por vida las cuales no son infrecuente.

ABSTRACT The Morroa aquifer, which is an essential source of water supply in Sucre, Colombia, with more than 500,000 users, may be at risk because of pesticide contamination that comes from different agricultural activities. The aim of this research was to evaluate the relationship between the presence of pesticides and the physicochemical properties of soils in the most vulnerable areas of the Morroa aquifer. Therefore, farmers were surveyed about pesticide usage and soil samples which were taken for analysis of pesticide and physicochemical properties. The results demonstrated that soils in these areas were relatively homogeneous in terms of texture, pH, cation exchange capacity and organic matter content. Pesticides detected in these soils were malathion, β-BCH, p-p’DDE, m-p’DDD, p-p’DDT, endosulfan, endrincetone, chlorpyrifos, dieldrin, endosulfan-sulfate, heptachlor-epoxide, and parathion. Physicochemical properties such as pH and texture of soils and intrinsic characteristics of the pesticide were found as the most influential variables according to statistical results. This study also presents a map of the spatial distribution of pesticide concentration according to the concentration of pesticides, which constitutes an important tool for the planning of agricultural activities that supports decision-making and the implementation of measures to mitigate potential impacts caused by pesticide pollution.

RESUMO O aquífero de Morroa é uma fonte essencial para o abastecimento de água em Sucre, Colômbia, com mais de 500.000 usuários que podem estar em risco devido à contaminação por pesticidas que provêm de diferentes atividades agrícolas. O objetivo desta pesquisa foi avaliar a relação entre a presença de pesticidas e as propriedades físico-químicas dos solos nas áreas mais vulneráveis do Aquífero Morroa. Para isso foi aplicado um inquérito sobre a utilização de pesticidas aos agricultores e foram coletadas amostras de solo para análise de pesticidas e propriedades físico-químicas. Os resultados mostraram que os solos nestas áreas são relativamente homogéneos em termos de textura, pH, Capacidade de Troca Catiônica e Matéria Orgânica. Os pesticidas detectados nestes solos foram Malathion, β-BCH, p-p’DDE, m-p’DDD, p-p’DDT, Endosulfan, Endrincetone, Chlorpyrifos, Dieldrin, Endosulfan-Sulfate, Heptachlor-epóxido e Parathion. O pH, a textura do solo e as características intrínsecas do pesticida são as variáveis mais influentes de acordo com os resultados estatísticos. Este estudo também mostra a distribuição espacial da concentração de pesticidas em toda a área do aquífero. O mapa elaborado constitui uma ferramenta para o planeamento de atividades agrícolas que subsidia a tomada de decisões e a implementação de medidas para mitigar os potenciais impactos causados pela poluição causada pelos pesticidas.

Resumen El suero bovino fetal (FBS por sus siglas en inglés) es el suplemento más utilizado para el cultivo celular, ya que su compleja composición aporta los nutrientes necesarios para el crecimiento de la mayoría de las células. Es un subproducto de la industria cárnica, y su disponibilidad y producción dependen principalmente de dos factores externos incontrolables: las condiciones climáticas y los cambios en el consumo de carne vacuna. Se hizo una caracterización de un FBS que se obtuvo de la industria cárnica para su uso en el cultivo celular. Se realizaron pruebas de proteínas totales, osmolaridad, presencia o ausencia de agentes biológicos patógenos, pH, concentración de ADN, contaminantes biológicos, resultados negativos y viabilidad celular, siguiendo los estrictos lineamientos de calidad de la International Serum Industry Association (ISIA). Se compararon el FBS y el plasma derivados de la sangre de la industria cárnica con un FBS comercial. Se observaron diferencias entre los FBS en cuanto a las concentraciones de ADN y de proteína total, pero no para la osmolaridad y el pH. A pesar de las diferencias, la prueba de viabilidad no arrojó complicación para el crecimiento celular con cualquier de los sueros y el plasma. El suero obtenido de la industria cárnica podría mantener cultivos celulares y permitir la proliferación celular de manera indistinta del suero comercial. Además, si no se dispone de FBS, el plasma puede funcionar como sustituto para el mantenimiento de los cultivos celulares.

Abstract The present work aims to characterize a fetal bovine serum (FBS) obtained from the meat industry for use in cell culture. FBS is the most widely used supplement for cell culture since its complex composition provides the necessary nutrients for the growth of most cells. It is a by-product of the meat industry, and its availability and production depend mainly on two uncontrollable external factors, climatic conditions and changes in beef consumption. According to the strict quality features of the International Serum Industry Association (ISIA), tests for total proteins, osmolarity, presence or absence of pathogenic biological agents, pH, DNA concentration, biological contaminants, negative results, and cell viability were performed. The characterization of the serum in the DNA and total protein concentration tests showed significant differences. Additionally, osmolarity and pH did not present significant differences between groups. Regarding the viability test, no complication for cell growth was observed despite the differences found in the characterization. The results showed that the serum obtained from the meat industry could maintain cell cultures and allow cell proliferation compared to commercial serum. Furthermore, if FBS is not available, some kinds of plasma can be used as a surrogate to maintain cell cultures.

SUMMARY Vaccines prevent millions of deaths each year, and their efficacy and safety have been widely established. In economic terms, vaccination is one of the most cost-effective health interventions, generating significant savings and long-term economic growth. Adult vaccination has been shown to decrease morbidity and mortality associated with preventable Infectious diseases, reducing complications and hospitalizations, including admissions to intensive care units. We have prepared this consensus document in order to design a pragmatic, accessible and standardized vaccination scheme for adults, according to risk category and age, based on the available evidence of available vaccines and new vaccines, having used the third consensus of the Paraguayan Infectious Diseases Society of 2019 as a basis for the final recommendations.

RESUMEN Las vacunas previenen millones de muertes cada año y su eficacia y seguridad han sido ampliamente establecidas. En términos económicos, la vacunación es una de las intervenciones sanitarias más costo efectivas, generando un importante ahorro y crecimiento económico que supone a largo plazo. Se ha demostrado que la vacunación de adultos disminuye la morbilidad y la mortalidad asociadas a enfermedades infecciosas prevenibles, reduciendo las complicaciones y las hospitalizaciones, incluidos los ingresos a las unidades de cuidados intensivos. Hemos elaborado este documento de consenso con el objeto de diseñar un esquema de vacunación pragmático, accesible y estandarizado del adulto, según categoría de riesgo y edad, sobre la base de la evidencia disponible de vacunas accesibles y nuevas vacunas habiendo utilizado el Tercer Consenso de la Sociedad Paraguaya de Infectología del 2019 como base para las recomendaciones finales.

Abstract This study evaluates litterfall production, forest floor mass and leaf-litter decomposition and growth in an 8-year- old Eucalyptus grandis stand and 467 treesha-1 and in another 16-year-old Pinus elliottii stand with 533 treesha-1, in the northeast of Corrientes, Argentina. In each stand, three permanent plots of 1000 m2 were established. Four collectors of 1.0 m2 and 12 litterbags of 20 cm2 were randomly distributed in each plot. The measurements were made over 3 years. The relationship between environmental factors and leaf-litterfall was analyzed using the Pearson correlation coefficient (r). The E. grandis stand showed an annual increment (IMA) of 25.2 m3ha-1year-1, a mean annual litter production (PAL) of 10.1 Mgha-1, an annual decomposition constant (K) of 0.7 and a half-life time (THL) of 1.0 years. The P. elliottii stand presented an IMA of 26.1 m3ha-1year-1, a PAL of 14.3 Mgha-1, a K of 0.6 and a THL of 1.15 years. The highest material fall occurred during the summer for both species with maximum monthly mean values of 1.5 Mgha-1 for E. grandis and 2.3 Mgha-1 for P. elliottii. The leaves were the most representative component of the fallen material. The climatic variable that presented the highest correlation with material fall was the average monthly temperature. The dynamics observed in the stands, production, formation of mulch and its decomposition are characteristic of subtropical forests.

Resumen Este estudio evalúa la producción de hojarasca, la acumulación y descomposición del mantillo y el crecimiento en un rodal de Eucalyptus grandis de 8 años de edad y 467 árbolesha-1 y en otro de Pinus elliottii de 16 años de edad y 533 árbolesha-1, en el nordeste de Corrientes, Argentina. En cada rodal fueron instaladas 3 parcelas permanentes de 1000 m2. Se distribuyeron 4 canastos de 1,0 m2 y 12 litterbags de 20 cm2, por parcela. Las mediciones fueron realizadas durante 3 años. La relación entre factores ambientales y caída de hojarasca se analizó mediante el coeficiente de correlación de Pearson (r). El rodal de E. grandis presentó un incremento medio anual (IMA) de 25,2 m3ha-1año-1, una producción de hojarasca anual media (PHA) de 10,1 Mgha-1, una constante de descomposición anual (K) de 0.7 y un tiempo de media vida (TMV) de 1,0 año. El rodal de P. elliottii presentó un (IMA) de 26,1 m3ha-1año-1, PHA de 14,3 Mgha-1, K de 0,6 y un TMV de 1,15 años. La mayor caída de material se presentó durante el verano para ambas especies con valores medios mensuales máximos de 1,5 Mgha-1 para E. grandis y de 2,3 Mgha-1 para P. elliottii. Las hojas fueron el componente más representativo del material caído. La variable climática que presentó mayor correlación con la caída de material fue la temperatura media mensual. La dinámica observada en los rodales, producción, formación de mantillo y su descomposición es característica de los bosques subtropicales.

Abstract: En | Text: En | PDF: En

ABSTRACT Objective: Our aim was to assess the ability of serum magnesium (Mg), measured on the first postoperative day (Mg1PO), to predict the need for calcium (Ca) replacement in patients undergoing total thyroidectomy (TT). Subjects and methods: Eighty patients undergoing TT, with Mg1PO and PTH dosage in the first (PTH1h) and eighth (PTH8h) hours after TT, were evaluated for the need for Ca replacement. Data were evaluated by uni/multivariate logistic regression and Receiver Operating Characteristic (ROC) curve. Results: 32 patients (40%) required Ca replacement. Median PTH1h, PTH8h and Mg1PO were higher in the no replacement group: 17 versus (vs) 3 pg/mL (p < 0.001), 18.2 vs 3.0 pg/mL (p < 0.001) and 2 vs 1.6 mg/dL (p < 0.001), respectively. Mg1PO was the isolated predictor for this replacement (odds ratio = 0.0004, 95% confidence interval: 0.000003-0.04; p = 0.001), with the cut-off value of 1.8 mg/dL showing sensitivity and specificity of 78.1% and 87.5%, respectively. Conclusions: In this group of patients, serum Mg1PO was the isolated predictor for the need for Ca replacement.

ABSTRACT Objective: To describe the results of upper eyelid blepharoplasty performed with radiosurgery in patients with upper eyelid dermatochalasis. Methods: A longitudinal descriptive study was carried out with patients from the ophthalmology service at Hospital Clínico Quirúrgico Hermanos Ameijeiras, from January 2021 to December 2022. After applying the selection criteria, the sample was made up of the first 50 patients who attended consecutively. Results: Patients aged 60-79 years predominated, as well as the female sex and the white skin color (p > 0.05). A complete reduction of redundant skin was achieved in more than 50 %. The average surgical time with radiofrequency was 35.9 min. Patient satisfaction was good in 96 %. Postoperative complications were present in 32 % of patients, only in two patients were they serious, but did not leave any sequelae. Conclusions: Radiowave surgery for treating dermatochalasis allows to achieve the desired aesthetic outcome, with satisfaction for both the physician and the patients, who achieve an improvement in their quality of life.

Resumen Descripción del caso clínico: Varón de 47 años con sintomatología inespecífica del tracto urinario inferior. Se le practica una uretroscopia en la que se aprecia un pequeño orificio en la porción inferior de la uretra bulbar por el que no se puede progresar. En la uretrografía retrograda se observa una pequeña cavidad de 8 mm bajo la uretra, compatible con siringocele. Se completa estudio mediante uretrosonografía retrograda donde se aprecia una cavidad de 22x4 mm (APxL) sin apreciar el orificio. Finalmente, mediante uretrosonografía retrograda con contraste ecográfico se apreció el orificio y un tamaño del siringocele de 35x5 mm (APxL). Relevancia: El caso pone de manifiesto como las nuevas técnicas de imagen pueden contribuir en el estudio de la patología uretral. Implicaciones clínicas: El hecho de que el siringocele sea muy poco frecuente en adultos y en muchas ocasiones asintomático puede provocar que su estudio mediante los protocolos habituales no sea óptimo produciéndose falsos negativos, infraestimaciones de su tamaño, errores en su clasificación o errores diagnósticos. Conclusiones: La uretrosonografía retrograda simple y la uretrosonografía retrograda con contraste ecográfico son técnicas de utilidad en el estudio del siringocele.

Abstract Description of the clinical case: 47-year-old male with nonspecific symptoms of the lower urinary tract. A urethroscopy is performed in which a small hole can be seen in the lower portion of the bulbar urethra through which progress cannot be made. Retrograde urethrography shows a small 8-mm cavity under the urethra, consistent with a syringocele. The study was completed by means of retrograde urethrosonography where a 22x4 mm cavity (APxL) was observed without appreciating the orifice. Finally, retrograde urethrosonography with ultrasound contrast revealed the orifice and a syringocele size of 35x5 mm (APxL). Relevance: The case shows how new imaging techniques can contribute to the study of urethral pathology. Clinical implications: The fact that syringocele is very rare in adults and is often asymptomatic can mean that its study using the usual protocols is not optimal, producing false negatives, underestimates of its size, errors in its classification or diagnostic errors. Conclusions: Simple retrograde urethrosonography and retrograde ultrasound contrast urethrosonography are useful techniques in the study of syringocele.
