ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Resumen En la crianza artificial de becerras es necesario reemplazar la leche para disminuir los costos de alimentación. Por ello, el objetivo del trabajo fue evaluar el uso de lactosuero fresco y enriquecido como sustituto de la leche entera en el sistema de crianza artificial de becerras Jersey. Se utilizaron 24 becerras de 31 ± 2,8 kg de peso, repartidas en tres tratamientos: T1) leche entera + concentrado + pasto (Cynodon nlemfuensis), T2) lactosuero fresco enriquecido + concentrado + pasto y T3) lactosuero fresco + concentrado + pasto. Se evaluó ganancia diaria de peso, consumo de concentrado, parámetros de fermentación ruminal y degradación in vitro del pasto. Se utilizó un diseño completamente al azar. La ganancia de peso fue similar para T1 y T2 (0,840 kg y 0,780 kg; p < 0,05), mientras que el consumo de concentrado fue similar para todos los tratamientos. El volumen máximo (VM: T1: 174,36 mL/g de MS, T2: 196,30 mL/g de MS y T3: 200,46 mL/g de MS; p > 0,05) y fase lag (L: T1: 1,36 h; T2: 1,22 h y T3: 0,68 h; p > 0,05) del pasto fue similar entre los tratamientos evaluados. A los 30 días, la mayor degradación se encontró en T1; sin embargo, a los 90 días no se encontraron diferencias. Se concluye que el uso del lactosuero fresco enriquecido es viable para reemplazar la leche en la crianza artificial de becerras Jersey.

Abstract In artificial calf rearing it is necessary to replace milk to reduce feed costs. Therefore, the objective of the work was to evaluate the use of fresh and enriched whey as a substitute for whole milk in the artificial rearing system of Jersey calves. Twenty-four calves weighing 31 ± 2.8 kg were used, divided into three treatments: T1) whole milk + concentrate + grass (Cynodon nlemfuensis), T2) enriched fresh whey + concentrate + grass and T3) fresh whey + concentrate + grass. Daily weight gain, concentrate consumption, ruminal fermentation parameters and in vitro degradation of the pasture were evaluated. A completely randomized design was used. Weight gain was similar for T1 and T2 (0.840 and 0.780 kg; P<0.05). While the consumption of concentrate was similar for all treatments. The maximum volume (Vm: T1: 174.36, T2: 196.30 and T3: 200.46 mL / g of MS; P>0.05) and lag phase (L: T1: 1.36; T2: 1.22 and T3: 0.68 h; P>0.05) of the pasture was similar between the evaluated treatments. At 30 days, the greatest degradation was found in T1. However, at 90 days no differences were found. It is concluded that the use of enriched fresh whey is viable to replace milk in artificial rearing of Jersey calves.

Abstract: Small-scale tilapia production contributes to sustainable rural development; however, it can be stagnated due to parasite diseases. This work aimed to determine the prevalence and intensity of infection of trichodinids and monogeneans on farmed tilapia in rural areas of Guerrero, Oaxaca and Chiapas, located in southwestern Mexico. A total of six trichodinid (Trichodina centrostrigeata, T compacta, T. heterodentata, T. magna, T. nigra y Trichodina sp.) and nine monogenean (Cichlidogyrus cirratus, C. dossoui, C. halli, C. mbirizei, C. sclerosus, C. thurstonae, C. tilapiae, Gyrodactylus cichlidarum y Scutogyrus longicornis) species were identified. The findings of C. mbirizei y C. cirratus represent new geographic records for Mexico. Trichodinid and monogenean infections occurred, respectively, at 73 and 93% of farms, distributed in coastal areas and mountain valleys. The prevalence of trichodinids was high (60-100%) in 30% of farms, whereas the median intensity was <10 trichodinids per fish. The prevalence of monogeneans was high and median intensities ranged between 1 and 30 at most farms. These results suggest that parasites can potentially occur everywhere; therefore, better management practices should be implemented to prevent parasite outbreaks.

Resumen: Las granjas pequeñas de tilapia contribuyen al desarrollo rural sostenible; pero los parásitos pueden afectar su productividad. El objetivo del presente estudio fue determinar la prevalencia e intensidad de tricodínidos y monogeneos en granjas de tilapia de Guerrero, Oaxaca y Chiapas. Se identificaron seis especies de tricodínidos: Trichodina centrostrigeata, T. compacta, T. heterodentata, T. magna, T nigra y Trichodina sp.; y nueve de monogeneos: Cichlidogyrus cirratus, C. dossoui, C. halli, C. mbirizei, C. sclerosus, C. thurstonae,C. tilapiae, Gyrodacty lus cichlidarum y Scutogyrus longicornis. Siendo los registros de C. mbirizei y C. cirratus nuevos para México. Los tricodínidos y monogeneos se presentaron, respectivamente, en 73 y 93% de las granjas muestreadas, tanto en regiones montañosas, valles y costas. La prevalencia de tricodínidos fue alta (60-100%) en 30% de las granjas, pero la intensidad mediana fue menor a 10 parásitos por pez. Mientras que la prevalencia de monogeneos fue alta en la mayoría de las granjas, pero la intensidad mediana fue baja (1 a 30). Estos resultados sugieren que los parásitos tienen el potencial de distribuirse en cualquier granja, por lo que las prácticas de manejo deben ser mejoradas y reducir así posibles brotes parasitarios que afecten la salud de los peces.

Abstract Introduction: This article summarizes the clinical practice guideline (CPG) for the initial pharmacological treatment of lupus nephritis in the Social Security of Peru (EsSalud). Objective: To provide evidence-based clinical recommendations for initial pharmacological treatment of non-refractory adults with class I to V lupus nephritis in EsSalud. Methods: A guideline development group (GDG) was formed, which included specialist physicians and methodologists, who formulated clinical questions. Systematic searches were conducted for systematic reviews and - when deemed relevant - primary studies in PubMed during 2021. Evidence was selected to answer each of the clinical questions posed. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic working meetings, the GEG used the GRADE methodology to review the evidence and formulate recommendations. The CPG was reviewed by external experts before its approval. Results: The CPG addressed 6 clinical questions, divided into 2 topics: initial treatment of the induction and maintenance phase. Based on these questions, 11 recommendations were formulated (all conditional), 22 points of good clinical practice, and 2 flow charts. Conclusion: Evidence-based recommendations were issued for the management of patients with this pathology.

Resumen La bioacústica permite monitorear murciélagos difícilmente detectados con métodos tradicionales, como las redes de niebla, y permiten obtener información sobre diferentes aspectos de la biología de las especies de estudio. En los últimos años se ha incrementado el interés por la aplicación de estos métodos y, en consecuencia, ha sido rápido el desarrollo de los equipos de grabación ultrasónica y las herramientas de análisis. Sin embargo, en el Neotrópico la bioacústica de murciélagos está en etapa de crecimiento en algunos países y apenas ahora está apareciendo en otros, por lo cual es necesario fortalecer este campo para estudiar la alta diversidad taxonómica y funcional de la región. En este contexto, es indispensable contar con bibliotecas de señales acústicas, que sirvan como referencia para identificar, validar y comparar las grabaciones de diferentes especies y localidades. Algunos países del Neotrópico han avanzado en este proceso y están construyendo estas bibliotecas de referencia. En Colombia, el trabajo a futuro implica un reto, debido a las más de 200 especies de murciélagos presentes. Este trabajo presenta las bases metodológicas para tomar grabaciones de referencia de murciélagos en Colombia y generar una guía para aquellos que se están iniciando en este campo de investigación.

Abstract Bioacoustic tools allow monitoring bats usually not detected with traditional methods, such as mist nets, and also provide information about different biological aspects of the species. The interest in applying these methods has increased in the last years, and consequently, there has been a rapid development of ultrasonic recording equipment and analysis tools. However, in the Neotropics, bat bioacoustics is emerging in some countries and just appearing in others; therefore it is necessary to reinforce this field to study the high taxonomic and functional diversity of the region. Therefore, it is essential to have bat call libraries that serve as a reference to validate and compare recordings from different species and localities. Some countries in the Neotropics have advanced in this process and are already building these reference libraries. In Colombia, the future work is challenging, due to the more than 200 bat species present. This paper establishes the methodological basis to obtain bat-reference calls in the Colombia and allow those who are just starting out in this research field.

Resumo Pseudoaneurismas micóticos da artéria femoral superficial (AFS) são raros, e geralmente são secundários à colonização de uma placa aterosclerótica durante bacteremia. Relatamos o caso de um paciente masculino diabético de 68 anos que chegou ao Serviço de Emergência com pirexia e massa expansiva dolorosa na coxa esquerda. Apresentava histórico de diarreia e havia sido tratado 16 dias antes para pseudoaneurisma da AFS, que foi excluído com stent coberto e sem antibioticoterapia adjuvante. A angiotomografia computadorizada demonstrou um abscesso ao redor dos vasos femorais e trombose do stent. Sob anestesia geral, realizamos desbridamento extenso, remoção do material endovascular, ligadura de AFS e antibioticoterapia empírica. Culturas de sangue e tecidos foram positivas para Escherichia coli. Na consulta de seguimento aos 3 meses, o paciente negou claudicação. Em pacientes selecionados, pseudoaneurismas micóticos podem ser tratados com ligadura de AFS.

Abstract Mycotic pseudoaneurysms of the superficial femoral artery (SFA) are rare and are usually secondary to colonization of an atherosclerotic plaque during an episode of bacteremia. We describe the case of a 68 year-old diabetic male who presented to the Emergency Department with pyrexia and a painful expanding mass in the left thigh. He had a history of diarrhea and had been treated 16 days earlier for an SFA pseudoaneurysm that had been excluded with a covered stent with no adjunctive antibiotic therapy. Angio CT showed an abscess surrounding femoral vessels and stent thrombosis. Under general anesthesia, we performed extensive debridement, removal of the endovascular material, SFA ligation, and empirical antibiotic therapy. Blood and tissue cultures were positive for Escherichia coli. At the 3-months follow up visit, the patient reported he had no claudication. In selected patients, mycotic pseudoaneurysms can be treated by SFA ligation.

ABSTRACT In Ecuador, one of the main hazards for threatened marine species, such as sea turtles, is small-scale fisheries bycatch. At a global scale, currently, bycatch reduction technologies (BRTs) are being tested in many coastal nations to mitigate this issue. Despite some advances in Ecuadorian efforts for wildlife protection, BRTs to reduce bycatch have yet to be assessed. The purpose of this study was to test the BRT of net illumination using violet light-emitting diodes (LEDs) as a mitigation measure to reduce sea turtle interactions in the small-scale driftnet fishery operating from the ports of Santa Rosa, Puerto Lopez and Jaramijo. A total of 146 pairs of experimental sets (control and illuminated panes) were deployed in all ports. A generalized linear mixed-effect model (GLMM) was employed to analyze the bycatch per unit of effort (BPUE) for sea turtles, and the catch per unit of effort (CPUE) for target species; for both control and illuminated panes. Thirty-two sea turtles from three species were observed captured: olive ridley Lepidochelys olivacea (n=18), green Chelonia mydas (n=13) and leatherback turtles Dermochelys coriacea (n=1). Turtle species-specific modeling showed bycatch of green turtles declined by 93% in illuminated nets compared with control, non-illuminated nets, whereas no significant difference between control and illuminated nets was observed for olive ridley turtles. The catch per unit effort of the pelagic fish species including skipjack tuna, yellowfin tuna, mahi-mahi, thresher shark and smooth hammerhead shark was not affected by net illumination. Our results represent the first evaluation of the effects of net illumination using LEDs on reducing marine turtle bycatch in Ecuadorian small-scale driftnet fisheries. Despite its relatively small sample size, these results could be used by fisheries managers to support the implementation or further testing of this BRT in gillnet fisheries along the Ecuadorian coast.

Summary This work focuses on knowing the differences in the academic performance of children’s education students according to sex and mother tongue. To this end, and starting from the different scenarios presented by multiculturality, we have taken into account the peculiarities of this cultural diversity reflected in the classroom. On the basis that we are in a context in which an official language and a cultural dialect coexist. The sample consisted of 489 children’s education students from 12 public educational establishments and 3 concerted centres, aged 5 to 6 (M= 5.23; DT= 506), of which 51.4 percent were boys (n=249) and 48.6 percent girls (n=235) of which 37.7% had Spanish as their mother tongue (n=183) and 62.3% Darija (n=302). The multidimensional instrument of basic skills in Child Education was used (Mateos y Olmedo, 2018). The results of ANOVA analysis and binary logistic regression showed that the mother tongue is the main cause of these children’s differences, negatively affecting those who have mother tongue Castilian, being clearly defined that the main weakness is shown in the areas of oral expression, written expression and phonetic consciousness.

Resumen Este trabajo se centra en conocer las diferencias en el rendimiento académico de los alumnos de Educación Infantil según el sexo y la lengua materna. Para ello, y partiendo de los distintos escenarios que nos presenta la multiculturalidad, hemos tenido en cuenta las peculiaridades de esta diversidad cultural reflejadas en el aula, sin olvidar que nos encontramos en un contexto en el que coexiste una lengua oficial y un dialecto cultural. La muestra estuvo integrada por 489 alumnos de Educación Infantil de 12 centros educativos públicos y 3 centros concertados, de edades comprendidas entre 5 y 6 años (M= 5.23; DT= .506); de estos el 51.4% eran niños (n=249) y el 48.6% niñas (n=235), de los cuales el 37.7% tenían como lengua materna familiar el castellano (n=183) y el 62.3% el darija (n=302). Se utilizó el instrumento multidimensional de competencias básicas en Educación Infantil (Mateos y Olmedo, 2018). Los resultados de los análisis ANOVA y regresión Logística Binaria evidenciaron que la lengua materna es la principal causa de las diferencias de estos niños, afectando negativamente a aquellos que tienen lengua materna castellana, quedando claramente definido que la principal debilidad se muestra en las áreas de la expresión oral, la expresión escrita y la conciencia fonética.

ABSTRACT This study analyzes the effectiveness of online training in a large organization. We tested the influence of different training processes, such as learning strategies, reactions, support of transfer, and barriers, on behavioral transfer and job performance. The participants were 3,600 employees of a Brazilian public bank after taking part in online training at work. Six months later, their supervisors evaluated the influences of the training on their subordinates' work behaviors. Findings indicated that in self-evaluation behavioral transfer was predicted by elaboration/practical application learning strategies, trainees' reactions to training, organizational, and peer support; motivation control, cognitive/help-seeking, and elaboration/practical application learning strategies, along with trainees' reactions to training, were significantly related to job performance. In hetero-evaluation, supervisor support contributed to explaining behavioral transfer, and cognitive/help-seeking strategies explained job performance. The mediating role of reactions to training was identified, and support of transfer showed marginal moderating effects.

RESUMEN Este estudio analiza la efectividad de la formación en línea en una gran organización. Se ha probado la influencia de diferentes procesos de la formación, como las estrategias de aprendizaje, las reacciones, el apoyo a la transferencia y las barreras, en la transferencia del comportamiento y el desempeño laboral. Los participantes fueron 3,600 empleados de un banco público brasileño que participaron en una formación en línea en el trabajo. Seis meses después, sus supervisores evaluaron las influencias de la formación en el comportamiento laboral de sus subordinados. Los hallazgos indicaron que en la autoevaluación la transferencia del comportamiento se predijo mediante estrategias de aprendizaje de elaboración/aplicación práctica, reacciones a la formación, apoyo organizacional y de pares; las estrategias de control de la motivación, cognitivas/búsqueda de ayuda y elaboración/aplicación práctica, junto con las reacciones a la formación, se relacionaron significativamente con el desempeño laboral. En la heteroevaluación, el apoyo del supervisor contribuyó a explicar la transferencia del comportamiento y las estrategias cognitivas/búsqueda de ayuda explicaron el desempeño laboral. Se identificó el papel mediador de las reacciones a la formación y el apoyo a la transferencia mostró efectos moderadores marginales.

Summary Currently, antibiotic resistance and indiscriminate use of chemical fungicides in agriculture need to be addressed. This research evaluated the inhibitory effect of aqueous, methanolic, acetonic and hexanic extracts from leaf and stem of Vitex mollis Kunth (Lamiaceae) against several bacteria (Escherichia coli, Micrococcus luteus, Salmonella enterica and Staphylococcus aureus) and species of Fusarium fungus (F. verticillioides, F. oxysporum, F. tapsinum and F. oxysporum f.sp. lycopersici), and determined their general chemical composition. The minimum inhibitory concentration (MIC) was determined by the micro-dilution technique for all extracts, except for the hexanic extract which did not show inhibition on the bacteria studied. S. enterica was the bacterium that showed the highest sensitivity to the methanolic extracts from stem (MIC = 28 µg mL-1), followed by M. luteus (MIC = 32 µg mL-1), S. aureus (MIC = 75 µg mL-1) and E. coli (MIC = 80 µg mL-1). The methanolic and aqueous extracts from the stem presented higher percentage of inhibition against different types of Fusarium evaluated by the agar dilution method. Extracts of V. mollis inhibited F. verticillioides between 62 and 91 % with 120 µg mL-1 of extract. The order of fungi species as inhibited by the extracts was F. verticillioides > F. oxysporum > F. tapsinum > F. oxysporum f.sp. lycopersici. The chemical composition of the species was determined by tests for phenols, tannins, flavonoids, triterpenes, alkaloids, coumarins and saponins. None of the extracts presented alkaloids and saponins. Phenols (37.1 mg EAG/g dry sample) and flavonoids (26.8 mg EQ/g dry sample) were the major compounds in the methanolic and aqueous extracts. In conclusion, small amounts of extracts are required to inhibit bacteria and Fusarium; hence, V. mollis can be considered a source of metabolites for this purpose and in agriculture as an alternative control within an integrated management of diseases.

Resumen Actualmente existe la necesidad de hacer frente al problema de la resistencia a los antibióticos y al uso indiscriminado de fungicidas químicos en la agricultura. El objetivo de este trabajo fue evaluar el efecto inhibitorio de extractos acuosos, metanólicos, acetónicos y hexánicos de hoja y tallo de Vitex mollis Kunth (Lamiaceae) contra diferentes bacterias (Escherichia coli, Micrococcus luteus, Salmonella enterica y Staphylococcus aureus) y especies del hongo Fusarium (F. verticillioides, F. oxysporum, F tapsinum y F. oxysporum f.sp. lycopersici) de importancia en la salud y en la agricultura, así como determinar su composición química general. Se determinaron las concentraciones inhibitorias mínimas (CIM) de todos los extractos por la técnica de microdilución, excepto del hexánico, que no presentó inhibición en las bacterias estudiadas. S. enterica fue la bacteria que mostró mayor sensibilidad al extracto metanólico de tallo (CIM = 28 µg mL-1), le siguieron M. luteus (CIM = 32 µg mL-1), S. aureus (CIM = 75 µg mL-1) y E. coli (CIM = 80 µg mL-1). Los extractos metanólicos y acuosos de tallo presentaron mayor porcentaje de inhibición contra los diferentes tipos de Fusarium evaluados por el método de dilución en agar. Los extractos de V. mollis inhibieron a F. verticillioides entre 62 y 91 % con 120 µg mL-1 de extracto. El orden de las especies de hongos inhibidas por los extractos fue: F. verticillioides > F. oxysporum > F. tapsinum > F. oxysporum f.sp. lycopersici. La composición química de las especies se determinó mediante pruebas para fenoles, taninos, flavonoides, triterpenos, alcaloides, cumarinas y saponinas. Ninguno de los extractos presentó alcaloides y saponinas. Los fenoles (37.1 mg EAG/g muestra seca) y flavonoides (26.8 mg EQ/g muestra seca) fueron los compuestos mayoritarios en los extractos metanólicos y acuosos. En conclusión, se requieren cantidades muy pequeñas de extracto para la inhibición de bacterias y de Fusarium; por lo tanto, V. mollis puede ser considerada una fuente de metabolitos para este fin y en la agricultura como control alternativo dentro de un manejo integrado de enfermedades.

Abstract Since learning strategies seem to be an important set of variables to explain the effectiveness of training and e-learning in organizations is here to stay, this paper aimed to analyze the factor structure and psychometric properties of a Learning Strategies Scale (LSS) and its relationship with the training transfer in an e-learning corporate context. A total of 3600 employees of a Brazilian bank participated in this study by responding to the LSS after taking part in an online course. We measured training transfer with self-evaluation and hetero-evaluation scales. Internal consistency, confirmatory factor analysis, and multiple regressions were conducted. A four-factor structure and an acceptable level of fit for the model were found. All types of learning strategies were related to training transfer in self-evaluation, and the cognitive and help-seeking strategies contributed to explain training transfer in hetero-evaluation. As a reliable and valid measure that predicts the effectiveness of training and job performance, participants should be advised about the learning strategies that produce better performance results at the workplace. Future research should use it in different contexts and samples, analyzing its relationships with other workplace variables.

Abstract Introduction: studies about the Nutritional Transition in Spain (NTS) until the mid-20th century are based on direct, and heavily aggregated, consumption estimates, a methodology that obscures important aspects of this process. Objective: to show the new possibilities of study opened by the analysis of hospital diets and to suggest new NTS indicators based on the menus provided by the Hospital Provincial in Valencia (HPV) and the Hospital Sant Jaume in Olot (HSJO), between 1900 and 1936. Method: we have calculated food and nutrient consumption among patients and hospital staff as well as among different groups of the population, and compared the results thus obtained with those calculated for the whole of Spain in the previous article in this supplement. Results: hospital menus contributed to disseminate certain strategic foodstuffs for the NTS: milk, eggs and fresh meat first, and fish, vegetables and fruit later. The public dissemination of these foodstuffs was, however, uneven, and deficits in the intake of micro- and macro-nutrients intake decreased at different paces, according to social group. Conclusions: hospital diets confirm that nutrition in Spain improved in the decades that preceded the Civil War, as well as the pioneering role that sanitary institutions played in this process. The data also suggests that the process operated at different paces in the reduction of deficits in the intake of certain nutrients according to age groups and socio-economic status.

Resumen Introducción: los estudios sobre la transición nutricional española (TNE) hasta mediados del siglo XX se basaban en estimaciones indirectas y muy agregadas del consumo que no permiten conocer aspectos importantes de aquel proceso. Objetivo: mostrar las nuevas posibilidades de estudio que proporcionan las dietas hospitalarias y proponer nuevos indicadores de la TNE a partir de las estimadas en el Hospital Provincial de Valencia (HPV) y en el Hospital Sant Jaume de Olot (HSJO) entre 1900 y 1936. Método: calculamos el consumo de alimentos y nutrientes de pacientes y empleados en aquellos hospitales y en diferentes subgrupos de población del primero. Contrastamos nuestros resultados con los obtenidos para España en el artículo anterior de este suplemento. Resultados: las dietas hospitalarias contribuyeron a difundir alimentos estratégicos de la TNE: primero, leche, huevos y carne fresca, y después, pescado fresco, verduras y frutas. La difusión de estos alimentos, sin embargo, fue desigual entre la población y no redujo con la misma intensidad los déficits en la ingesta de macronutrientes y micronutrientes. Conclusiones: las dietas hospitalarias confirman la mejora del estado nutricional de la población española en las décadas anteriores a la Guerra Civil y el papel pionero que tuvieron las instituciones sanitarias en este proceso. No obstante, también muestran diferentes cronologías en la reducción de los déficits de importantes nutrientes entre grupos de edad y estatus socioeconómico.

The purpose of this study was to evaluate the effect of 12 combinations of salinity and temperature on larval growth of Litopenaeus vannamei, starting in nauplius V (NV) and ending at postlarva (PL1), a process which lasted seven days. The results show that the larvae have greater length and weight at temperatures of 30 to 35°C in combination with salinities between 25 and 35. In conclusion, salinity and temperature are important factors to consider for the production of larvae of L. vannamei.

ABSTRACT: Zoonotic parasitic infections are a major global public and veterinary health problem and widespread among stray dogs. The objective of this study was to establish the prevalence of intestinal parasites in stray dogs in the urban, rural and coastal areas of Mexicali County in northwest Mexico. In 2014, from January to December, 380 stray dogs were captured. The entire small intestine, cecum and faeces samples were collected and examined by using simple zinc sulfate flotation and Lugol’s solution staining. Data were statistically analysed. Overall, about 21.5% of examined dogs were found positive for intestinal parasites. Toxocara canis was the most frequent detected parasite, with a prevalence of 7.1%, followed by Toxascaris leonina (5.5%), Cystoisospora spp. (5.0%), Taenia spp. (3.9%) and Dipylidium caninum (2.8%). Dogs were more frequently found to be infected with a single genus of intestinal parasite (18.7%) than co-infected (2.8%). Intestinal parasites were more prevalent in samples from the coastal area (25%) than in those from the rural (24.4%) and urban (20.6%) areas, however, only statistical association was found between capture area and specific intestinal parasitic infection. There were significant differences in the prevalence of taeniasis among two age groups (P<0.01). A seasonal peak of prevalence for intestinal parasitic infections was found during spring (P<0.05), corresponding with a seasonal peak of prevalence of T. canis (P<0.05). The wide range of isolated parasites indicated that people residing in this area are at risk of exposure to these potentially hazardous zoonotic pathogens.

RESUMEN: Las infecciones zoonóticas parasitarias son un problema global público y para la medicina veterinaria, siendo diseminadas por perros callejeros. El objetivo del estudio fue determinar la prevalencia de parasitosis intestinales en perros callejeros de la zona urbana, rural y costera del municipio de Mexicali, noroeste de México. En 2014, entre enero y diciembre, se capturaron 380 perros. Se colectó el intestino, ciego y heces y se examinaron utilizando flotación con sulfato de zinc y tinción con la solución de Lugol. Los datos fueron analizados estadísticamente. En general, alrededor del 21,5% de los perros examinados fueron positivos a parásitos intestinales. Toxocara canis fue el parásito más frecuentemente, con una prevalencia del 7,1%, seguido por Toxascaris leonina (5,5%), Cystoisospora spp. (5,0%), Taenia spp. (3,9%) y Dipylidium caninum (2,8%). Los perros fueron más frecuentemente encontrados infectados con un solo género de parásito intestinal (18,7%) que coinfectados (2,8%). Las parasitosis intestinales fueron más prevalentes en muestras de la costa (25%) que del área rural (24,4%) y urbana (20,6%), sin embargo solo se encontró asociación estadística entre el área de captura y las parasitosis intestinales específicas. Hubo diferencias significativas en la prevalencia de taeniasis entre los dos grupos de edad (P<0,01). El pico estacional de la prevalencia de infecciones parasitarias intestinales se encontró durante la primavera (P<0,05), correspondiendo con el pico estacional de T. canis (P<0,05). La amplia gama de parásitos aislados indicó que las personas que residen en esta zona están en riesgo de exposición a estos patógenos zoonóticos potencialmente peligrosos.
