1. Laryngomalacia and failure to thrive – A case report

Author: Rita Barroca Macedo, Maria Sousa Dias, Luís Salazar, Pedro Alexandre, Catarina Viveiros, Marco Pereira, and Jorge Spratley
Subjects: laryngomalacia, failure to thrive, stridor, flexible fibreoptic laryngoscopy, supraglottoplasty, gastro-oesophageal reflux, Medicine, Pediatrics, RJ1-570
Abstract: Introduction: Laryngomalacia (LGM) is the most common congenital anomaly of the larynx and the most frequent cause of stridor in the newborn. Even though it can be a source of concern and anxiety to parents, a large majority of cases usually resolve spontaneously within 18 months of life. However, in infants with signs of severity, a multidisciplinary approach and surgical intervention might be necessary. Case report: We report the case of a full-term 7-week-old infant girl, previously hospitalized in the Neonatal Intensive Care Unit and diagnosed with type II LGM (Olney’s classification). She presented to the Paediatric Emergency Department with stridor at rest, vigorous chest wall retractions and poor weight gain (increase of 10 g/day, weight under the 3rd percentile). The infant was admitted to monitor respiratory symptoms and investigate her failure to thrive. However, irrespective of feeding modifications, and after exclusion of other causes of failure to thrive, the infant maintained an insufficient weight gain. Additionally, respiratory symptoms remained exuberant and surgical intervention was determined as the optimal treatment. At 3 months old, supraglottoplasty was performed. At 18 months, she has a weight in the 3rd-15th percentile range (WHO curves) and is clinically asymptomatic. Conclusion: LGM is a remarkably frequent cause of stridor in infants, but only a rare number of cases require other interventions beyond symptomatic measures. In this report, surgical intervention was of paramount importance to ensure normal growth, emphasising the impact of a multidisciplinary approach in such cases.

2. Prevalência e Impacto da Enurese Noturna em Crianças em Idade Escolar: Estudo em Quatro Unidades de Saúde Familiar do Grande Porto

Author: Rita Correia, Johandry Duarte, Luís Salazar, Ana Catarina Coelho da Silva, Inês Pinto de Sousa, and Paula Pires de Matos
Subjects: enurese noturna, comorbilidades, prevalência, qualidade de vida, pediatria, medicina geral e familiar, Medicine, Medicine (General), R5-920
Abstract: Introdução: A enurese noturna (EN) tem uma prevalência de 5%-15% nas crianças em idade escolar (IE) e pode estar associada ao impacto na qualidade de vida (QdV) nas crianças e famílias. Com este trabalho, pretende-se estimar a prevalência da EN nas crianças em IE em quatro unidades de saúde familiares (USF) na região Norte e avaliar o impacto na QdV. Métodos: Estudo multicêntrico transversal e descritivo conduzido nas USF em estudo, após aprovação pela Comissão de Ética. Convidaram-se oportunisticamente as crianças em IE, que compareceram nas consultas programadas, para preenchimento de um questionário anónimo. A análise estatística foi conduzida com recurso ao Excel® e SPSS®. Resultados: Registaram-se 158 participantes, 60,1% do sexo feminino, com mediana de idades de 6 anos (IIQ 5-7). Identificaram-se 18 crianças enuréticas (11,4%), sendo que destas a maioria era do sexo masculino (66,7%), e tinha entre 5 e 6 anos (66,7%). Encontrou-se relação significativa entre EN e sexo (p=0,014), história familiar (HF) (p=0,021) e perdas urinárias diurnas (p=0,034). Relativamente à QdV (n=14), as subescalas mais afetadas foram as relações familiares, a autoestima e as relações sociais. Conclusão: Apesar da amostra reduzida condicionar a interpretação de resultados, a prevalência de EN obtida e a associação positiva entre EN e sexo masculino e HF são concordantes com a bibliografia. Além disso, a avaliação da QdV mostrou impacto negativo nas crianças e famílias. Desta forma, salienta-se a importância da abordagem e orientação adequadas desta patologia.

3. Hyperbaric Medicine in Pediatrics — reality of a Portuguese reference center

Author: Catarina Freitas, Luís Salazar, Sílvia Duarte-Costa, Catarina Fraga, Sara Monteiro, and Óscar Camacho
Subjects: Pediatrics, Hyperbaric oxygen therapy, Pediatrics emergency, Carboxyhemoglobin, RJ1-570
Abstract: ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

4. Maternal Left Ventricular Diastolic and Systolic Function during Normal Pregnancy in Saint Bernard Dogs

Author: Luís Lobo, Joana Esteves-Guimarães, Pedro Oliveira, Luís Salazar, André Pereira, and Ana Patrícia Fontes-Sousa
Subjects: dog, maternal cardiac function, doppler echocardiography, tissue doppler imaging, Veterinary medicine, SF600-1100
Abstract: This study aimed to evaluate maternal left ventricular (LV) systo-diastolic function using conventional and TDI echocardiography and included 10 healthy Saint-Bernard pregnant bitches. M-mode, peak transmitral flow velocities during early diastole (E) and atrial contraction (A), aortic and pulmonic flow, myocardial performance index (MPI), TDI studies (peak myocardial velocities during early diastole (E’), atrial contraction (A’) and peak systole (S’)), and blood pressure were measured at 21 to 28 (T1), 40 (T2) and 60 (T3) days of gestation and four to eight weeks postpartum (T4). Cardiac output and heart rate were 20% and 9% higher at T3, respectively, compared to T4 (p < 0.01). Lateral S’ was 36% higher at T3 than at T1 (p < 0.05). Changes in diastolic function were demonstrated by 10% lower E wave and 15% A wave at T1, compared to T4 (p < 0.05). E’ and A’ were 23% and 42% higher at T3 compared to T4 (p < 0.01). Both lateral E/E’ and E’/A’ were 6% and 19% lower at T3 compared to T1 (p < 0.01 and p < 0.05, respectively). At T3, MPI was 51% and 34% lower when compared to T1 or T2 (p < 0.05). The echocardiographic evaluation of maternal cardiac function is important, as structural, and functional changes occur throughout pregnancy.

Author: Daniel Orbe, Luis Salazar, and Paúl Vásquez
Subjects: distribución de energía, movilidad eléctrica, eficiencia energética, vehículos eléctricos, SUMO, Technology (General), T1-995
Abstract: La integración de la movilidad eléctrica es una realidad en el mundo actual, las políticas gubernamentales se enfocan cada vez más en incentivar el uso de vehículos eléctricos (VE) particulares, pero, principalmente en reemplazar la movilidad pública convencional por el uso de buses eléctricos. Una adecuada gestión energética de los sistemas de buses eléctricos debe optimizar el uso de recursos, prolongando la vida útil de las unidades de transporte, estaciones de carga y brindando siempre un servicio de calidad a sus usuarios. El desempeño del sistema de transporte mediante VE depende de diversas variables determinísticas y estocásticas que necesitan ser debidamente simuladas a fin de analizar su comportamiento, lo más cercano a las condiciones reales. En el presente trabajo, mediante la aplicación del software SUMO (Simulation of Urban Mobility), se ha implementado un modelo para el análisis energético de VE y se lo ha aplicado en rutas de transporte público en Quito-Ecuador. A partir de las simulaciones realizadas se ha estimado el consumo energético y se ha efectuado un análisis de sensibilidad del consumo energético de las unidades de buses eléctricos ante variaciones de parámetros relevantes en la gestión energética de sistemas de transporte público. Para el caso de estudio se comprueba la reducción de la autonomía del bus eléctrico en 27% de acuerdo con la información del fabricante. El análisis del desempeño energético realizado bajo diversos escenarios de tráfico permitirá en futuros trabajos optimizar la operación de los sistemas de transporte público eléctrico, considerando niveles de tráfico, flujo vehicular variable y pronunciados desniveles en su relieve.

Abstract: It is important to understand real-world BNT162b2 COVID-19 vaccine effectiveness (VE), especially among racial and ethnic minority groups. We performed a test-negative case-control study to measure BNT162b2 COVID-19 VE in the prevention of COVID-19-associated acute respiratory illness (ARI) hospitalizations at two Atlanta hospitals from May 2021–January 2023 and adjusted for potential confounders by multivariate analysis. Among 5139 eligible adults with ARI, 2763 (53.8%) were enrolled, and 1571 (64.5%) were included in the BNT162b2 analysis. The median age was 58 years (IQR, 44–68), 889 (56.6%) were female, 1034 (65.8%) were African American, 359 (22.9%) were White, 56 (3.6%) were Hispanic ethnicity, 645 (41.1%) were SARS-CoV-2-positive, 412 (26.2%) were vaccinated with a primary series, and 273 (17.4%) had received ≥1 booster of BNT162b2. The overall adjusted VE of the BNT162b2 primary series was 58.5% (95% CI 46.0, 68.1), while the adjusted VE of ≥1 booster was 78.9% (95% CI 70.0, 85.1). The adjusted overall VE of primary series for African American/Black individuals was 64.0% (95% CI 49.9, 74.1) and 82.7% (95% CI 71.9, 89.4) in those who received ≥1 booster. When analysis was limited to the period of Omicron predominance, overall VE of the primary series decreased with widened confidence intervals (24.5%, 95% CI −4.5, 45.4%), while VE of ≥1 booster was maintained at 60.9% (95% CI 42.0, 73.6). BNT162b2 primary series and booster vaccination provided protection against COVID-19-associated ARI hospitalization among a predominantly African American population.

Subjects: Specialties of internal medicine, RC581-951
Abstract: Introduction and Objectives: International studies have described an epidemiological change in patients with the hepatitis C virus (HCV), with greater involvement of young people and risk groups. The reality in Latin America, particularly in Chile, is unknown. This study aimed to epidemiologically characterize HCV patients treated in the Chilean public health system (period 2016-2021) and compare these characteristics in two periods (2016 - 2019 vs. 2020 - 2021). Materials and Methods: Historical cohort was constructed based on national data and the Hospital del Salvador registry (Santiago, Chile) (n=410). All patients diagnosed with HCV treated in the Chilean public system (2016-2019) and those treated at Hospital del Salvador (2020-2021 period) were included. It was registered: year of diagnosis, age, sex, presence of cirrhosis, HCV genotype, co-infection with hepatitis B virus (HBV) and/or HIV, need for a liver transplant, or intratreatment dead. Both periods were compared using the Mann-Whitney U test or Fisher's exact test, as appropriate. Results: 61.2% of patients were male, with a median age of 57 years. 73.5% presented genotype 1 and 11.6% genotype 4. There was a 19.3% coinfection with HIV. Only 1.4% had therapy failure at 24 weeks and 5.2% of patients underwent liver transplantation. When comparing the periods 2016 – 2019 vs. 2020 – 2021 a reduction in the median age 59 vs 49 (p

21. P-60 DETERMINATION OF THE PREVALENCE OF HEPATITIS C VIRUS USING THE RAPID MONTEBIO HCV TEST IN A HIGH-RISK POPULATION OF HOSPITAL DEL SALVADOR, CHILE.

Author: Alejandro Carvajal, Carlos Valdebenito, Luis Salazar, Gonzalo Veloso, Stephany Albán, and Gabriel Mezzano
Subjects: Specialties of internal medicine, RC581-951
Abstract: Introduction and Objectives: There are 71 million infected in the world and approximately 4 million in Latin America. In Chile, it is estimated that there are approximately 35-50 thousand infected, of which less than 10% have been identified and treated. This study aimed to determine the prevalence of anti-HCV in patients at high risk of infection using a rapid test for HCV. Materials and Methods: Cross-sectional and descriptive study, which examined 502 samples of capillary blood from patients of the Hospital del Salvador, based on risk factors for Hepatitis C. The commercial Montebio HCV test was used, which reports a sensitivity and specificity of 99%. Results: Of the total of 502 samples, 52.9% (266) corresponded to women. The average age was 51.5 years; the main risk factor was being older than 45 years (45.8%, 230/502), followed by being exposed to health personnel (34.5%, 173/502). 99.4% of the tests were validly performed. The positivity was 0.59% (3/502). Conclusions: The implementation of a rapid test as screening is a useful and cost-effective tool in populations with risk factors. In the population studied, there is a higher prevalence than that reported in other series.

Subjects: cardiac testing, cardiovascular disease, coronavirus, COVID-19, global health, Diseases of the circulatory (Cardiovascular) system, RC666-701
Abstract: Background: The coronavirus disease-2019 (COVID-19) pandemic significantly affected management of cardiovascular disease around the world. The effect of the pandemic on volume of cardiovascular diagnostic procedures is not known. Objectives: This study sought to evaluate the effects of the early phase of the COVID-19 pandemic on cardiovascular diagnostic procedures and safety practices in Asia. Methods: The International Atomic Energy Agency conducted a worldwide survey to assess changes in cardiovascular procedure volume and safety practices caused by COVID-19. Testing volumes were reported for March 2020 and April 2020 and were compared to those from March 2019. Data from 180 centers across 33 Asian countries were grouped into 4 subregions for comparison. Results: Procedure volumes decreased by 47% from March 2019 to March 2020, showing recovery from March 2020 to April 2020 in Eastern Asia, particularly in China. The majority of centers cancelled outpatient activities and increased time per study. Practice changes included implementing physical distancing and restricting visitors. Although COVID testing was not commonly performed, it was conducted in one-third of facilities in Eastern Asia. The most severe reductions in procedure volumes were observed in lower-income countries, where volumes decreased 81% from March 2019 to April 2020. Conclusions: The COVID-19 pandemic in Asia caused significant reductions in cardiovascular diagnostic procedures, particularly in low-income countries. Further studies on effects of COVID-19 on cardiovascular outcomes and changes in care delivery are warranted.

23. Impact of Paraffin Composition on the Interactions between Waxes, Asphaltenes, and Paraffin Inhibitors in a Light Crude Oil

Author: Oualid M'barki, John Clements, Luis Salazar, James Machac, and Quoc P. Nguyen
Subjects: paraffin composition, wax appearance temperature (WAT), asphaltenes-wax interactions, alpha olefin-maleic anhydride polymers, Chemistry, QD1-999
Abstract: The effect of wax molecular weight distribution on the efficacy of two alpha olefin-maleic anhydride paraffin inhibitors (PIs) having different densities of alkyl side-chains were examined in light West Texas crude in the absence and presence of asphaltenes. Interpretation of the data was aided by cross-polarization microscopy. Primary differences in wax crystal morphology appear to be driven by the composition of the wax, with secondary differences being associated with the choice of PI. In the absence of asphaltenes, the effect of wax composition on PI performance (i.e., reducing oil viscosity and wax appearance temperature) is greater for the PI having the higher chain density, with the one having the lower chain density being generally more effective regardless of the wax composition. These differences are diminished in the presence of asphaltenes such that the PI having the higher chain density is somewhat more effective. Trends in both morphology and viscosity suggest a steric effect associated with wax composition that is lessened on interaction of the PIs with asphaltenes.

24. Evaluation of a SARS-CoV-2 Capture IgM Antibody Assay in Convalescent Sera

Author: Binh Ha, Samadhan Jadhao, Laila Hussaini, Theda Gibson, Kathy Stephens, Luis Salazar, Caroline Ciric, Meg Taylor, Nadine Rouphael, Srilatha Edupuganti, Christina A. Rostad, S. Mark Tompkins, Evan J. Anderson, and Larry J. Anderson
Subjects: SARS-CoV-2, COVID-19, capture IgM ELISA, IgG ELISA, antibody duration, Microbiology, QR1-502
Abstract: ABSTRACT Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for a global pandemic with over 152 million cases and 3.19 million deaths reported by early May 2021. Understanding the serological response to SARS-CoV-2 is critical to determining the burden of infection and disease (coronavirus disease 2019 [COVID-19]) and transmission dynamics. We developed a capture IgM assay because it should have better sensitivity and specificity than the commonly used indirect assay. Here, we report the development and performance of a capture IgM enzyme-linked immunosorbent assay (ELISA) and a companion indirect IgG ELISA for the spike (S) and nucleocapsid (N) proteins and the receptor-binding domain (RBD) of S. We found that among the IgM ELISAs, the S ELISA was positive in 76% of 55 serum samples from SARS-CoV-2 PCR-positive patients, the RBD ELISA was positive in 55% of samples, and the N ELISA was positive in 15% of samples. The companion indirect IgG ELISAs were positive for S in 89% of the 55 serum samples, RBD in 78%, and N in 85%. While the specificities for IgM RBD, S, and N ELISAs and IgG S and RBD ELISAs were 97% to 100%, the specificity of the N IgG ELISA was lower (89%). RBD-specific IgM antibodies became undetectable by 3 to 6 months, and S IgM reached low levels at 6 months. The corresponding IgG S, RBD, and N antibodies persisted with some decreases in levels over this time period. These capture IgM ELISAs and the companion indirect IgG ELISAs should enhance serologic studies of SARS-CoV-2 infections. IMPORTANCE Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has inflicted tremendous loss of lives, overwhelmed health care systems, and disrupted all aspects of life worldwide since its emergence in Wuhan, China, in December 2019. Detecting current and past infection by PCR or serology is important to understanding and controlling SARS-CoV-2. With increasing prevalence of past infection or vaccination, IgG antibodies are less helpful in diagnosing a current infection. IgM antibodies indicate a more recent infection and can supplement PCR diagnosis. We report an alternative method, capture IgM, to detect serum IgM antibodies, which should be more sensitive and specific than most currently used methods. We describe this capture IgM assay and a companion indirect IgG assay for the SARS-CoV-2 spike (S), nucleocapsid (N), and receptor-binding domain (RBD) proteins. These assays can add value to diagnostic and serologic studies of coronavirus disease 2019 (COVID-19).

25. P-67 ULTRASOUND GUIDED TRANSIENT ELASTOGRAPHY FOR THE DIAGNOSIS AND STAGING OF LIVER FIBROSIS

Author: Juan Francisco Rozas, Katherine González, Luis Salazar, Máximo Cattaneo, Juan Pablo Roblero, Alvaro Urzúa, Alexandra Sandoval, and Jaime Poniachik
Subjects: Specialties of internal medicine, RC581-951
Abstract: Introduction: Transient elastography (TE) is a non-invasive method for the evaluation of liver fibrosis. Up to 20% of measurements fail, possibly due to the choice of probe position. Objectives: To evaluate the use of ultrasound as a position guide (UPG) prior to TE to improve the measurement of liver stiffness (LS). Methods: Prospective study of 237 patients (age 54 ± 14 years, 69% women) referred for TE (FibroScan, Echosens). The main indication was non-alcoholic fatty liver disease (52.3%). 65.4% of the patients were overweight or obese. LS was measured in each patient according to the manufacturer's recommendations and at the same appointment, in UPG. Fibrosis staging sections recommended by the manufacturer were used. Statistical analyzes performed with chi-square and t-test (p

Subjects: clustering, data mining, DBSCAN, K-Means, HDBSCAN, Bibliography. Library science. Information resources
Abstract: Compliance with the basic conditions of quality in higher education implies the design of strategies to reduce student dropout, and Information and Communication Technologies (ICT) in the educational field have allowed directing, reinforcing, and consolidating the process of professional academic training. We propose an academic and emotional tracking model that uses data mining and machine learning to group university students according to their level of dropout risk. We worked with 670 students from a Peruvian public university, applied 5 valid and reliable psychological assessment questionnaires to them using a chatbot-based system, and then classified them using 3 density-based unsupervised learning algorithms, DBSCAN, K-Means, and HDBSCAN. The results showed that HDBSCAN was the most robust option, obtaining better validity levels in two of the three internal indices evaluated, where the performance of the Silhouette index was 0.6823, the performance of the Davies–Bouldin index was 0.6563, and the performance of the Calinski–Harabasz index was 369.6459. The best number of clusters produced by the internal indices was five. For the validation of external indices, with answers from mental health professionals, we obtained a high level of precision in the F-measure: 90.9%, purity: 94.5%, V-measure: 86.9%, and ARI: 86.5%, and this indicates the robustness of the proposed model that allows us to categorize university students into five levels according to the risk of dropping out.

Author: Abdullah Ghali, Luis Salazar, David Momtaz, Gautham Prabhakar, Preston Richier, and Anil Dutta
Subjects: Orthopedic surgery, RD701-811
Abstract: Femoral-facial syndrome (FFS) is an exceedingly rare congenital disorder of unknown etiology related to maternal diabetes during pregnancy. It is characterized by variations of bilateral femoral hypoplasia and facial anomalies. We discuss an interesting case of a 3-year-old girl with FFS with an extensive surgical history who presented to a pediatric orthopaedic clinic with ankle pains and absent femurs. As this disease process is not frequently encountered, it is imperative for the practicing clinician to be aware of the various presentations. In this study, we discuss the different orthopaedic presentations in the literature and discuss various management recommendations.

Abstract: Se planteó el presente estudio con el objetivo de estudiar la dinámica de la concentración y la acumulación de nutrimentos en árboles de Cedrela odorata L. (Meliaceae), para mejorar el conocimiento y la gestión de las plantaciones forestales tropicales. Mediante una serie falsa de tiempo (crono secuencia) compuesta por 15 plantaciones en bosque Muy Húmedo Tropical de Costa Rica, se determinó la biomasa aérea, la concentración de nutrimentos y se estimó su acumulación en los componentes de la biomasa en árboles seleccionados. Como resultado se obtuvo que la concentración de los nutrimentos presentó tendencia a disminuir en el orden: nitrógeno > potasio > magnesio > calcio > azufre > fósforo para los macro nutrimentos, mientras que los micro elementos siguen la secuencia hierro > boro > zinc > manganeso > cobre > aluminio. Destacaron los altos valores de concentración de potasio medidos en los pecíolos (1,46 ± 0,48%) en contraste con contenidos más bajos de este elemento en el follaje (1,09 ± 0,21%). Se desarrolló modelos de regresión lineal para evaluar el comportamiento de la concentración de nutrimentos y se observó tendencia a la disminución de la concentración nitrógeno, fósforo, potasio y magnesio con el incremento de la edad, al ser este comportamiento más evidente en el potasio del fuste. Por otro lado, los modelos de regresión generados para evaluar el comportamiento de la acumulación de nutrimentos en los distintos componentes de la biomasa presentaron un comportamiento exponencial, con significancia estadística principalmente en el fuste y en el total acumulado. Dichos modelos permiten estimar posibles salidas de nutrimentos del sitio de plantación durante la cosecha, así como el reciclaje de cantidades de nutrimentos en componentes de la biomasa que permanecen en el sitio de plantación.

Author: Luis Salazar Caraballo, Jeison Pérez,, Jesús Chamorro Morán, René Patiño-Pardo, and Diego Carrillo-González
Subjects: Porcinos, reproducción, semen, zinc, selenio, Agriculture, Agriculture (General), S1-972, Animal culture, SF1-1100
Abstract: It was evaluated the addition effect of different concentrations of a mineral supplement, on the seminal characteristics of boars. The essay was developed in Sincelejo municipality. The experiment consisted in three cycles of mineral supplementation, where was supplied 10, 20 and 30 g/day daily in every pig, per cycle. Every cycle had a duration of 55 days, obtaining 1 ejaculate/pig/week (10 ejaculates/cycle). The seminal collects where taken making use of the hand gloved method. After the collect where made, the semen was transported to the laboratory, where it was processed and realized its respective evaluation of seminal quality (macroscopic and microscopic variables). The results evidenced that seminal volume, spermatic motility (individual, progressive), spermatic morphology (tails) and spermatic vitality, showed probability values associated to a lineal effect (P0,05). Finally, it was evidenced an effect of the supplementation levels on seminal aspect, but neither pH nor seminal color (P>0,05). It can be concluded that dietary micromineral supplementation favors some seminal variables such as volume and concentration, maintaining the others characteristics, within normal parameters.

43. Anaerobic co-digestion of vinasse and chicken manure: alternative for Colombian agrowaste management

Author: José Daniel Marin Batista, Luis Salazar, Liliana Castro, and Humberto Escalante
Subjects: Anaerobic Co digestion, vinasse, Chicken manure, Biomethane potential test, Biotechnology, TP248.13-248.65
Abstract: Anaerobic digestion is an attractive technology for waste management meanwhile energy is recovering. This study evaluated the feasibility of codigesting vinasse and chicken manure (CM) as management alternative for Colombian agro industries. Biochemical methane potential was tested for different vinasse to CM ratios of 1:0, 3:1, 1:3 and 0:1 on VS basis. Vinasse and CM ratio of 3:1 increased the specific methane production up to 55% regard to the weighted specific methane production of 0.65 m3CH4/kg VS. Mixtures between the substrates had a positive synergistic effect. CM improved buffer capacity diminishing the risk on acidification by drastic pH shift during vinasse digestion. Furthermore, vinasse allowed dilution of total ammonia nitrogen concentration avoiding ammonia inhibition. Since a higher methane production, vinasse and CM co-treatment improves the energy-recovery and economic feasibility of installing biogas plant as part of the ethanol production chain.

Abstract: El sistema de producción porcina en Colombia, ha tenido un gran crecimiento en los últimos años, gracias a la implementación de técnicas como la inseminación artificial, la cual permite realizar un mejoramiento genético incrementando la productividad. Sin embargo, el modelo de manejo de los reproductores y donantes de semen no es el adecuado, siendo mantenidos en confinamiento, alimentados con dietas que no suplen los requerimientos de micronutrientes (Zn y Se) alterando la calidad seminal. Por lo anterior, se han propuesto modelos de suplementación con microminerales, tales como el Zinc y el Selenio. En el presente artículo se recopila, relaciona y discute, los diferentes efectos de la suplementación con estos microminerales, sobre los distintos mecanismos fisiológico-moleculares que afectan las principales características seminales del cerdo.

Subjects: coffea arabica, almácigo, densidad crítica, meloidogyne exigua, tolerancia, producción mínima, Agriculture, Agriculture (General), S1-972
Abstract: El objetivo del estudio fue evaluar el efecto de densidad creciente de Meloidogyne exigua sobre el desarrollo de plantas de almácigo. Se trasplantaron plántulas de café variedad caturra a bolsas de polietileno con 1335 cm3 de sustrato desinfectado, para establecer un ensayo con diseño de bloques completos al azar, con 8 repeticiones. Los tratamientos aplicados consistieron de poblaciones iniciales (Pi) de 0; 0,125; 0,25; 0,5; 1; 2; 4; 8; 16; 32 y 64 huevos+J2/ cm3 de sustrato, aplicadas un mes después del trasplante. El modelo y=m+(1-m) ZP-T aplicado 234 días después del trasplante para la altura, diámetro, número de nudos y peso fresco aéreo, indicó que el límite de tolerancia (T) fue de 0,66; 0,06; 0,13 y 0,88 huevos+J2/cm3, respectivamente; la producción mínima relativa (m) fue de 0,79; 0,79; 0,33 y 0,54 respectivamente, a Pi iguales o mayores a 64 huevos+J2/cm3. El índice de agallas alcanzó el máximo a partir de una Pi de 2; el pico máximo de nematodos en el suelo y las raíces se alcanzó con Pi entre 2 y 4; mientras la tasa máxima de reproducción fue de 114 con Pi de 0,125. Se concluyó que la densidad crítica fue cercana a cero huevos/cm3 de sustrato como población inicial, y que el almácigo se debe desarrollar libre de nematodos, ya que aún con Pi bajas se puede alcanzar la máxima población en corto tiempo.

Abstract: In Mexico one in 14 deaths are caused by diabetes mellitus (DM) or by the macro and microvascular disorders derived from it. A continuous hyperglycemic state is characteristic of DM, resulting from a sustained state of insulin resistance and/or a dysfunction of β-pancreatic cells. Acaciella angustissima is a little studied species showing a significant antioxidant activity that can be used as treatment of this disease or preventive against the complications. The objective of this study was to explore the effect of oral administration of A. angustissima methanol extract on physiological parameters of streptozotocin-induced diabetic rats. The results indicated a significant reduction in blood glucose levels, an increase in serum insulin concentration, a decrease in lipid levels and an improvement in the parameters of kidney damage by applying a concentration of 100 mg/Kg B.W. However, glucose uptake activity was not observed in the adipocyte assay. Moreover, the extract of A. angustissima displayed potential for the complementary treatment of diabetes and its complications likely due to the presence of bioactive compounds such as protocatechuic acid. This study demonstrated that methanol extract of Acacciella angustissima has an antidiabetic effect by reducing the levels of glucose, insulin and improved physiological parameters, hypolipidemic effect, oxidative stress and renal damage in diabetic rats.

49. Detección de meloidogyne incognita en tubérculos de papa en Costa Rica

Author: Zeidy Montero, Catalina García, Luis Salazar, Roberto Valverde, and Luis Gómez-Alpízar
Subjects: papa, meloidogyne, diseño perineal, caracterización molecular, pcr, Agriculture, Agriculture (General), S1-972
Abstract: Especies del género Meloidogyne causan importantes daños al cultivo de la papa (Solanum tuberosum L) alrededor del mundo. Su efecto puede ser directo al disminuir el rendimiento o indirecto al infectar los tubérculos y causar agallas o protuberancias, que les confiere una apariencia verrugosa, que afecta su calidad y reduce su valor comercial. En Capellades y Llano Grande de Cartago, Costa Rica, fueron encontrados tubérculos de papa, de la variedad Floresta y del clon Bananito, con numerosas protuberancias en su superficie. De las protuberancias se extrajo hembras ovígeras de Meloidogyne spp. Estudios morfológicos (diseño perineal de las hembras) y moleculares (PCR y PCRRFLP) mostraron que las hembras extraídas de las protuberancias pertenecen a la especie M. incognita. Se recomienda estudiar las causas que promueven la infección de los tubérculos en ambas localidades, ya que cerca del 90% del área cultivada de papa en el país corresponde a la variedad Floresta. En adición, se debe prestar especial atención a las zonas semilleristas, ya que los tubérculos-semilla podrían servir como fuente de inóculo y contribuir a la diseminación del patógeno a otras áreas.
