ABSTRACT The aim of this study was to evaluate the effect of the agroecological zone on the textile characteristics of the alpaca fibre (Vicugna pacos) from herds of productive units of the dry Puna and wet Puna in the Puno region, according to sex and age. The samples were obtained from 5530 Huacaya alpacas. Fibre diameter (FD), Standard Deviation of Fibre Diameter (SDFD), Coefficient of Variation of Fibre Diameter (CVDF), Spin Fineness (SF), Curvature Index (ICur) and Standard Deviation of Curvature Index (SDICur) were recorded using the OFDA 2000 equipment. The effects of the agroecological zone in relation to sex and age (Deciduous teeth [DL], 2 teeth [2D], 4 teeth [4D] and all teeth [BLL]) were estimated using a randomized design with factorial arrangement and Duncan's multiple range test. The FF values are in the range of 13.3 to 34.5 µm with an average value of 20.32 µm. The alpacas from the wet Puna presented lower FD (13.3-34.5 µm) compared to those from the dry Puna (13.6-37.9 µm). Age and sex affect the FD, as BLL alpacas registered a higher FF compared to the DL alpacas (p<0.05). Likewise, a lower FD was observed in male alpacas compared to females (p<0.05). The correlation between agroecological zones, sex and age was demonstrated by obtaining a smaller diameter in male DL alpacas from wet Puna. In addition, a significant correlation was identified between the fibre quality evaluated from its textile characteristics with the agroecological zone.

RESUMEN El objetivo del estudio fue evaluar el efecto de la zona agroecológica en las características textiles de la fibra de alpaca (Vicugna pacos), procedente de rebaños de unidades productivas de la Puna seca y Puna húmeda en la región Puno, según sexo y edad. Las muestras fueron obtenidas de 5530 alpacas Huacaya. El Diámetro de fibra (DF), Desviación estándar del diámetro de fibra (DEDF), Coeficiente de variación de diámetro de fibra (CVDF), Finura al hilado (FH), Índice de curvatura (IC) y Desviación estándar del índice de curvatura (DEIC) fueron registrados utilizando el equipo OFDA 2000. Los efectos de la zona agroecológica con relación al sexo y edad (Diente de leche [DL], 2 dientes [2D], 4 dientes [4D] y Boca llena [BLL]) se estimaron mediante un diseño al azar con arreglo factorial y prueba de rango múltiple de Duncan. Los valores de DF se encuentran en el rango de 13.3 a 34.5 µm con un valor promedio de 20.32 µm. Las alpacas de la Puna húmeda presentaron menor DF (13.3-34.5 µm) en comparación con las de la Puna seca (13.6-37.9 µm). La edad y el sexo inciden en el DF, pues las alpacas BLL registraron mayor DF frente a las alpacas DL (p<0.05). Asimismo, se observó un menor DF en alpacas macho en comparación con las hembras (p<0.05). La correlación entre zonas agroecológicas, sexo y edad se demostró al obtener menor diámetro en las alpacas macho DL de Puna húmeda. Además, se identificó una correlación significativa entre la calidad de fibra evaluada a partir de sus características textiles con la zona agroecológica.

ABSTRACT BACKGROUND: In Latin America, liver cancer is one of the top causes of cancer mortality. It is the fifth most common cause of death among malignant tumors in Mexico and is the leading cause in Hidalgo State (43.8% of the population living in poverty). OBJECTIVE: To conduct a correlational analysis on the main risk factors for liver cancer in Hidalgo State, Mexico, including municipal disaggregation and comparison with the national level. DESIGN AND SETTING: Cross-sectional, correlational, descriptive and comparative epidemiological study using Mexican governmental databases covering 1990-2019. METHODS: A comprehensive review of the databases of the General Directorate of Health Information (DGIS) was performed to analyze official death figures, hospital discharges and national and municipal population projections, using specific search criteria defined in the Global Burden of Disease classification, based on the risk factors for liver cancer. RESULTS: Liver cancer rates showed an evident rise in Hidalgo (183%), moving from 21st place in Mexico in 1990 to 9th place in 2019. This increase was correlated with alcoholism. An increasing trend for liver cancer deaths, of 133.89%, is projected for 2030. Females and the population over 60 years of age are more affected. There are some critical regions with liver cancer death rates twice the national rate or more. CONCLUSION: Targeted effective public health strategies should be structured by identifying, characterizing and regionalizing critical marginalized municipalities that are vulnerable to alcoholism and other risk factors for liver cancer. This approach may be helpful for other states in Mexico or similar countries.

ABSTRACT The Brewery Hatuey takes more than 94 years of exploitation contributing to the contamination of the river Yarayó and the bay of Santiago from Cuba. In the 2020 due to the pandemic were carried out modifications in the products to elaborate what influenced in that the DBO5 overcame in 4,52 times and the DQO in 6,88 times the permissible maximum limits settled down by the normative Cuban for to pour of residual waters to terrestrial waters and the sewer system. It was evidenced that the concentration of heavy metals, electric conductivity, as well as the nitrogen content and match stayed inside that settled down by to pour norm and that although the norm settles down that it should not exist suspended solids superior values they are reported to the 100 mg/L. A parameter that overcomes in 7,4 times what indicates the Cuban norm is the fats and oils, for what intends the installation of a float associated to the technological proposal of treatment that exists for this industry. It will also be necessary to neutralize the residual.

RESUMEN La Cervecería Hatuey lleva más de 94 años de explotación contribuyendo a la contaminación del río Yarayó y la bahía de Santiago de Cuba. En el 2020 debido a la pandemia se realizaron modificaciones en los productos a elaborar lo que influyó en que la DBO5 superara en 4,52 veces y la DQO en 6,88 veces los límites máximos permisibles establecidos por la normativa cubana para el vertimiento de aguas residuales a aguas terrestres y al alcantarillado. Se evidenció que la concentración de metales pesados, conductividad eléctrica, así como el contenido de nitrógeno y fósforo se mantuvieron dentro de lo establecido por la norma de vertimiento, y que a pesar de que la norma establece que no deben existir sólidos suspendidos, se reportan valores superiores a los 100 mg/L. Un parámetro que supera en 7,4 veces lo que indica la norma cubana son las grasas y aceites, por lo que se propone la instalación de un flotador asociado a la propuesta tecnológica de tratamiento que existe para esta industria. Además será necesario neutralizar el residual.

Resumo Objetivo Estimar a prevalência de níveis inadequados de vitamina D e seus fatores associados para mulheres em idade fértil no Brasil. Métodos Uma revisão sistemática foi realizada (última atualização em maio de 2020). As meta-análises foram realizadas usando o inverso da variância para o modelo fixo com cálculo de proporção sumarizada por transformação arco-seno duplo de Freeman-Tukey. A qualidade metodológica e de reporte foi avaliada usando a ferramenta do Joanna Briggs Institute para estudos de prevalência. Resultados Nossa revisão identificou 31 estudos, compreendendo 4.006 participantes. Todos os estudos apresentaram pelo menos uma limitação, principalmente devido ao uso de amostra de conveniência e tamanho amostral pequeno. As prevalências gerais de deficiência, insuficiência e deficiência de vitamina D foram 35% (intervalo de confiança, IC 95%: 34-37%), 42% (IC 95%: 41-44%) e 72% (IC 95%: 71-74%), respectivamente. Conclusão Embora a magnitude da prevalência de níveis inadequados de vitamina D seja incerta, a evidência sugere que presença de deficiência ou insuficiência de vitamina D em mulheres em idade reprodutiva pode causar problemas moderados a graves.

Abstract Objective To estimate the prevalence of inadequate vitamin D level and its associated factors for women of childbearing age in Brazil. Methods A systematic reviewwas conducted (last updatedMay 2020).Meta-analyses were performed using the inverse-variance for fixed models with summary proportion calculation by Freeman-Tukey double arcsine. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. Results Our review identified 31 studies, comprising 4,006 participants. All the studies had at least one weakness, mainly due to the use of convenience sampling and small sample size. The overall prevalence of vitamin D deficiency, insufficiency, and both deficiency and insufficiency were 35% (confidence interval, 95%CI: 34-37%), 42% (95%CI: 41-44%), and 72% (95%CI: 71-74%), respectively. Conclusion Although the magnitude of the prevalence of inadequate levels of vitamin D is uncertain, the evidence suggests that presence of vitamin D deficiency or insufficiency in women of reproductive age can cause moderate to severe problems.

Abstract: Objective: Describe the prevalence of breast cancer (BC)-associated germline pathogenic variants (PVs) among Mexican patients with triple-negative BC (TNBC). Materials and methods: The spectrum of PVs identified among patients with TNBC who were enrolled in a prospective registry and underwent genetic testing was analyzed. Results: Of 387 patients with invasive TNBC and a median age at diagnosis of 39 years (range 21-72), 113 (29%) were carriers of PVs in BC-susceptibility genes: BRCA1 (79%), BRCA2 (15%), and other (6%: ATM, BRIP1, PALB2, PTEN, RAD51C, and TP53). PV carriers were younger at BC diagnosis (37 vs. 40 years, p=0.004) than non-carriers. Conclusion: A large proportion of TNBC in Mexican patients is associated with germline PVs, the vast majority in BRCA. The incremental yield of PVs in other BC-susceptibility genes was modest, and a stepwise approach starting with BRCA testing may be justified if it is more cost-effective than multigene panel testing.

Resumen: Objetivo: Describir la prevalencia de variantes patógenas (VPs) germinales en genes asociados con cáncer de mama (CM) en pacientes mexicanos con CM triple negativo (CMTN). Material y métodos: Se analizó el espectro de VPs identificadas en pacientes con CMTN que fueron incluidos prospectivamente en un registro y se realizó un estudio genético. Resultados: Se analizó un total de 387 pacientes con una mediana de edad al diagnóstico de 39 años; 113 (29%) eran portadores de VPs en genes de susceptibilidad a CM: BRCA1 (79%), BRCA2(15%), y otros (6%: ATM, BRIP1, PALB2, PTEN, RAD51C y TP53). Los portadores de VPs eran más jóvenes al diagnóstico de CM (37 vs. 40 años, p=0.004). Conclusiones: Existe una alta prevalencia de VPs en pacientes mexicanos con CMTN y la mayoría se encuentra en genes BRCA. La realización de pruebas genéticas se puede optimizar mediante la adopción de un proceso escalonado para la detección de VPs.

ABSTRACT Objective: To evaluate the effect of a telenursing intervention in the context of the pandemic to prevent childhood anemia in Peru. Material and Method: Pilot, analytical, quasi-experimental study with pre- and post-test. The sample consisted of 60 mothers from a primary health care facility in Lambayeque, Peru, who were selected at convenience and then assigned to a control group (30) and an experimental group (30), with the latter being subjected to a 4 months telenursing intervention. The effect was measured by comparing the average hemoglobin and dietary iron intake before and after the intervention. Hemoglobin level was determined biochemically through blood analysis. Dietary iron intake was collected through telephone interviews following a 24-hour recall. Results: The average hemoglobin level in the experimental group did not show significant differences between the beginning and the end of the intervention (p= 0.199); whereas in the control group, the average hemoglobin level showed significant differences between the beginning and the end of the intervention (p= 0.013). The average dietary intake of iron among the children of the control group (p= 0.049) and the experimental group (p= 0.000) had a significant difference between the beginning and the end of the intervention. Conclusion: The children who received the telenursing intervention suffered no anemia and the dietary iron intake increased, thus corroborating that telenursing programs have the potential of offering more information on nutrition, favoring the health of the child, the mother and the family.

RESUMEN Objetivo: Evaluar el efecto de una intervención de teleenfermería en contexto de pandemia para prevenir la anemia infantil en Perú. Material y Método: Estudio piloto, analítico, cuasi experimental con pre y pos-test. La muestra estuvo constituida por 60 madres de un establecimiento de atención primaria de Lambayeque, Perú, que fueron seleccionadas a conveniencia y luego asignadas al Grupo control (30) y Grupo experimental (30), este último sometido a una intervención de teleenfermería de 4 meses. El efecto se midió comparando el promedio de hemoglobina e ingesta alimentaria de hierro antes y después de la intervención. La hemoglobina fue determinada bioquímicamente a través del análisis de sangre; la ingesta alimentaria de hierro fue recogida mediante entrevistas telefónicas a través del recordatorio de 24 horas. Resultados: El promedio de hemoglobina en el grupo experimental no presentó diferencia significativa entre el inicio y el final de la intervención (p= 0,199); en el grupo control el promedio de hemoglobina presentó diferencias significativas entre el inicio y el final de la intervención (p= 0,013). El promedio de ingesta alimentaria de hierro en los niños del grupo control (p= 0,049) y experimental (p= 0,000) sí tuvieron diferencias significativas entre el inicio y el final de la intervención. Conclusión: Los niños que recibieron la intervención con teleenfermería se mantuvieron sin anemia y la ingesta alimentaria de hierro aumentó por lo que se corrobora que los programas de teleenfermería tienen el potencial de incrementar información sobre alimentación, favoreciendo la salud del niño, de la madre y la familia.

RESUMO Objetivo: Avaliar o efeito de uma intervenção de telenfermagem no contexto da pandemia para prevenir a anemia infantil no Peru. Material e Método: Estudo piloto, analítico, quase-experimental com pré e pós-teste. A amostra foi composta por 60 mães de uma unidade básica de saúde de Lambayeque, Peru, que foram selecionadas por conveniência e depois designadas para um dos dois grupos de pesquisa: grupo controle=30 e um grupo experimental=30, submetido esse último a uma intervenção de telenfermagem de 4 meses. O efeito foi medido comparando a hemoglobina média e a ingestão de ferro dietético antes e depois da intervenção. O nível de hemoglobina foi determinado bioquimicamente através da análise de sangue. A ingestão de ferro dietético foi coletada através de entrevistas telefónicas por meio de um recordátorio de 24 horas. Resultados: O nível médio de hemoglobina no grupo experimental não apresentou diferenças significativas entre o início e o final da intervenção (p= 0,199). No grupo controle, a hemoglobina média mostrou diferenças significativas entre o início e o final da intervenção (p= 0,013). A ingestão alimentar média de ferro entre as crianças do grupo controle (p = 0,049) e do grupo experimental (p = 0,000) teve uma diferença significativa entre o início e o final da intervenção. Conclusão: As crianças que receberam a intervenção de teleenfermagem não sofreram anemia e a ingestão de ferro por via alimentar aumentou, corroborando assim que os programas de teleenfermagem podem oferecer mais informações sobre a nutrição, favorecendo a saúde da criança, da mãe e da família.

ABSTRACT Objective To analyze the pattern of triggering and exacerbation of dermatological diseases between March and July 2020 and to compare this pattern to the corresponding period of 2019. Methods This was a quantitative, descriptive, comparative and documentary study that was carried out through the retrospective analysis of medical records (March to July 2019 and 2020) of individuals assisted at a private dermatology practice service located in the southern area of the city of São Paulo (SP). Results We evaluated 992 medical consultations in 2019 and 1,176 in 2020. In 2020, we observed a significant increase in cases of telogen effluvium (276%), psoriasis (1,400%), atopic dermatitis (178%), seborrheic dermatitis (200%), herpes zoster (1,200%) and vitiligo (433%). All diseases had stress as a possible initial trigger. In addition, fragile nail syndrome and contact dermatitis, pathologies associated with behavioral measures, also had an important increase in the prevalence (6,400% and 5,500%, respectively). However, the number of aesthetic procedures decreased by approximately 54% during the pandemic period. Conclusion During the pandemic period, the pattern of incidence of dermatoses had changed compared with the previous year. An emphasis was observed on diseases triggered by a psychological component, as well as those pathologies that have behavioral measures as the main cause. For this reason, the impacts of COVID-19 is greater than only among those infected.

ABSTRACT Objectives: The objective of the study was to determine the evolution of functional ability in patients over 65 years of age during the home care program in the Lleida Health Region and analyze the predictors of mortality. Methodology: The sample includes stays in the home care program (processes) of at least six months long over five years. The variables under study were functional ability at the beginning, in the middle, and at the end of the process, sociodemographic characteristics, chronic diseases, health status, socio-family problems, and mortality. Results: A total of 8,189 people were included with a total of 8,433 processes opened between the years 2011 and 2016. Functional ability worsened more in the early stages of the process, remaining more stable in the final phase. In older patients, with senile dementia and the presence of pressure ulcers, dependence increased as the process progressed. Conclusions: The results obtained in this study on the relationship of functional ability in the initial assessment and the increased risk of mortality are consistent with studies carried out.

RESUMEN Objetivos: Los objetivos del estudio fueron determinar la evolución de la capacidad funcional en mayores de 65 años de la Región Sanitaria de Lleida durante su estancia en el programa de atención domiciliaria (ATDOM), y analizar los factores predictores de mortalidad. Metodología: Se trata de un estudio longitudinal. La muestra incluye las estancias (procesos) ≥ 6 meses en el programa ATDOM ocurridos durante 5 años. Las variables a estudio fueron la capacidad funcional al ingreso, a la mitad y al final del proceso, las características sociodemográficas, las enfermedades crónicas, el estado de salud, los problemas sociofamiliares y la mortalidad. Resultados: Se incluyeron un total de 8.189 personas, con un total de 8.433 procesos abiertos entre los años 2011 y 2016. La capacidad funcional empeoró más en las primeras fases del proceso, y se mantuvo más estable en la fase final. En las personas más mayores, con demencia senil y con presencia de úlceras por presión, la dependencia aumentaba conforme avanzaba el proceso. Conclusiones: Los resultados obtenidos en este estudio sobre la relación de la dependencia funcional en la valoración inicial y el mayor riesgo de mortalidad son coincidentes con estudios desarrollados.

ABSTRACT BACKGROUND: Despite the several options available for supplements containing vitamins C and E, evidence regarding the prevalence of deficiency or insufficiency of these vitamins is weak. OBJECTIVES: To estimate the prevalence of deficiency or insufficiency of vitamins C and E and associated factors among women of childbearing age, in Brazil. DESIGN AND SETTING: Systematic review and meta-analysis conducted at a Brazilian public university. METHODS: A search from index inception until May 2020 was conducted. Meta-analyses were performed using inverse variance for fixed models, with summary proportions calculation using Freeman-Tukey double arcsine (base case). Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. RESULTS: Our review identified 12 studies, comprising 1,316 participants, especially breastfeeding women. There was at least one quality weakness in all studies, mainly regarding sampling method (i.e. convenience sampling) and small sample size. The prevalence of vitamin C deficiency ranged from 0% to 40%. Only vitamin E deficiency was synthetized in meta-analyses, with mean prevalences of 6% regardless of the alpha-tocopherol cutoff in plasma, and 5% and 16% for cutoffs of < 1.6-12.0 mmol/l and < 16.2 mmol/l, respectively. The cumulative meta-analysis suggested that a trend to lower prevalence of vitamin E deficiency occurred in recent studies. CONCLUSIONS: Although the studies identified in this systematic review had poor methodological and reporting quality, mild-moderate vitamin C and E deficiencies were identified, especially in breastfeeding women. Thus, designing and implementing policies does not seem to be a priority, because the need has not been properly dimensioned among women of childbearing age in Brazil. REGISTRATION NUMBER IN PROSPERO: CRD42020221605.

Resumen Antecedentes: A pesar de las políticas actuales de yodación de la sal, la deficiencia de yodo sigue siendo un problema de salud pública mundial, especialmente en las mujeres. Hasta ahora, se han sugerido pruebas contradictorias sobre la prevalencia de la deficiencia de yodo en Brasil. Objetivo: Estimar la prevalencia de deficiencia de yodo y factores asociados en mujeres en edad fértil, en Brasil. Métodos: Se realizó una revisión sistemática, buscando en PubMed, LILACS, OMS, Scopus y la base de datos de disertaciones y tesis de Capes desde el inicio hasta mayo de 2020. Se realizaron metanálisis de proporciones utilizando la variancia inversa para el modelo fijo. La calidad de información y metodológica se evaluó utilizando la herramienta del Institute Joanna Briggs para estudios de prevalencia. Resultados: Nuestra revisión identificó siete estudios publicados entre 2002 y 2017, incluyendo 1354 participantes, especialmente mujeres embarazadas. Todos los estudios presentaron al menos una limitación de calidad, principalmente con respecto al método de muestreo (es decir, la conveniencia) y el pequeño tamaño de la muestra. La prevalencia de la deficiencia de yodo varió entre los estudios del 16% y el 62%, mientras que el metanálisis identificó una prevalencia media del 40% (intervalo de confianza del 95%, IC 37%-43%) para las mujeres embarazadas y del 13% (IC del 95% 4%-24%) para mujeres no embarazadas. El metanálisis acumulativo sugiere una tendencia a una mayor prevalencia de deficiencia de yodo a partir de 2018 en mujeres embarazadas. Conclusiones: Si bien esta revisión sistemática identificó estudios con mala calidad metodológica y de reporte, se identificó una alta prevalencia de deficiencia de yodo en mujeres embarazadas, lo que refuerza la importancia de las políticas nutricionales nacionales para monitorear el estado de yodo en esta población. Los estudios futuros deben considerar el muestreo probabilístico aleatorio, el tamaño de muestra apropiado y el análisis de subgrupos predefinidos para informar adecuadamente la prevalencia de la deficiencia de yodo y los factores asociados en mujeres en edad fértil y para respaldar las políticas de salud.

Abstract Background: Despite current policies of salt iodination, iodine deficiency is still a global public health problem, especially in women. So far, conflicting evidence has been suggested for the prevalence of iodine deficiency in Brazil. Objective: To estimate the prevalence of iodine deficiency and associated factors in women of childbearing age in Brazil. Methods: A systematic review was conducted using databases (PubMed, LILACS, WHO, Scopus, and Capes’ dissertation and thesis), from inception to May 2020. Meta-analyses of proportions were performed using the variance inverse for the fixed model. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool to prevalence studies. Results: Our review identified seven studies published between 2002 e 2017, including 1354 participants, especially pregnant women. All studies presented at least one quality limitation, mainly regarding the sampling method (i.e., convenience) and small sample size. The prevalence of iodine deficiency ranged among studies from 16% to 62%. In contrast, the meta-analysis identified a mean prevalence of 40% (95% confidence interval, CI 37%-43%) for pregnant women and 13% (95% CI 4%-24%) for non-pregnant women. Cumulative meta-analysis suggests a tendency of higher iodine deficiency prevalence from 2018 in pregnant women. Conclusions: Although this systematic review identified studies with poor methodological and reporting quality, a high prevalence of iodine deficiency was identified in pregnant women, reinforcing the importance of national nutritional policies for monitoring iodine status in this population. Future studies should consider random probabilistic sampling, appropriate sample size, and pre-defined subgroup analysis to adequately inform the prevalence of iodine deficiency and associated factors in women of childbearing age and support health policies.

Abstract Adequate sustainable forest management, whether in a plantation or a natural forest, creates carbon sinks that are usually constant over time, however, it is unknown how it affects the activities of vegetation management in carbon sinks in the forest ecosystems. The objective was to estimate the carbon concentration in herbaceous and shrubs, leaf litter and two soil depths (0 to 15 cm and 15 to 30 cm), in a forest plantation with the presence of four tropical species under two management conditions. Carbon measurements were made in grasses and shrubs, leaf litter and two soil depths under two managed and unmanaged conditions in 30 plots with the presence of purple rose (Tabebuia rosea), teak (Tectona grandis), melina (Gmelina arborea) and parota (Enterolobium cyclocarpum). After the collection, the dry weight of each sample was weighed and determined, to determine the carbon content of each of the components. An Anova and Duncan’s test were then performed to determine if there are significant differences. The plot with parota and with management was the one that registered the highest amount of total carbon with 73.94 Mg ha-1, while the plot with teak with management reported the lowest total carbon content, with 45.63 Mg ha-1. As for the carbon content in the soil, it decreases by approximately 35%, as its depth increases, with significant differences.

Resumen Un adecuado manejo forestal sustentable, ya sea en una plantación o un bosque natural, se crean sumideros de carbono que suelen ser constante en el tiempo, sin embargo, se desconoce cómo afecta las actividades del manejo de la vegetación en los sumideros de carbono en los ecosistemas forestales. El objetivo fue estimar la concentración de carbono en herbáceas y arbustos, hojarasca y dos profundidades de suelo (0 a 15 cm y de 15 a 30 cm), en una plantación forestal con presencia de cuatro especies tropicales en dos condiciones de manejo. Se realizaron las mediciones de carbono en hierbas y arbustos, hojarasca y dos profundidades de suelo en dos condiciones con manejo y sin manejo en 30 parcelas con presencia de rosa morada (Tabebuia rosea), teca (Tectona grandis), melina (Gmelina arborea) y parota (Enterolobium cyclocarpum). Después de la colecta, se pesó y se determinó el peso seco de cada muestra, para determinar el contenido de carbono por cada uno de los componentes. Después se realizó un Anova y la prueba de Duncan para determinar si existen diferencias significativas. La parcela con parota y con manejo fue la que mayor cantidad de carbono total registró con 73.94 Mg ha-1, mientras que la parcela con teca con manejo reportó el menor contenido de carbono total, con 45.63 Mg ha-1. En cuanto al contenido de carbono en el suelo este disminuye en 35% aproximadamente, conforme aumenta su profundidad, existiendo diferencias significativas.
