The Relationship between Ultrarunning Status, Subjective Well-being, and Life Satisfaction

The COVID-19 pandemic resulted in a rise in mental health challenges across the United States. Consequently, two important well-being measures for Healthy People 2030—subjective well-being and life satisfaction—were negatively impacted. A plethora of evidence exists about the benefits of running for physical and mental health. Yet, there is no available evidence that shows the benefits of ultrarunning, subjective well-being, and life satisfaction. This quantitative cross-sectional study examined the relationship between ultrarunning status, subjective well-being, and life satisfaction among adult runners in the United States. The advanced triangle of epidemiology served as the conceptual framework. A convenience sample included 369 adult runners, who were recruited via the Survey Monkey online platform and through running and ultramarathon groups. Subjective well-being was measured using the Warwick Edinburgh Mental Well-being Scale, and life satisfaction was measured using the Satisfaction with Life Scale. Two hierarchical multiple linear regressions were conducted. The results showed that there was a statistically significant association between the agent (subjective well-being), the host (ultrarunners), and the environment (ultrarunning), adjusting for demographic characteristics, F (1,364) = 3.79, p = .050, R2 = .01. However, there was no statistically significant association between the agent (life satisfaction), the host (ultrarunners), and the environment (ultrarunning), adjusting for demographic characteristics, F (1,364) = 1.74, p = .188, R2 = .00. Implications for positive social change include helping public health officials create initiatives that improve well-being through community programs, leisure engagements, research, and policy

Desarrollo a Escala Humana y Resiliencia en las comunidades Samulalí y El Jícaro asociadas a la Unión de Campesinos Organizados de San Dionisio (UCOSD)

La presente investigación pretende realizar un análisis del Desarrollo a Escala Humana y la resiliencia en las comunidades de Samulalí y El Jícaro asociadas a la Unión de Campesinos Organizados de la cuenca de San Dionisio UCOSD. Con el propósito de mejorar la calidad de vida de las personas desde el aspecto organizacional, a partir de los aprendizajes familiares y la forma en que éstas logren alcanzar los niveles de resiliencia óptimos en sus respectivas parcelas. La metodología utilizada fue por medio de un estudio de caso a través de vivencias y experiencias compartidas con los socios. Se ejecutaron en dos etapas; la primera fue a través de la aplicación de la matriz de necesidades y satisfactores de Max Neef y la segunda se realiza con la descripción de las parcelas para identificar el nivel de resiliencia en el que se encuentran. El tipo de estudio realizado en esta investigación es descriptivo-analítico, cualitativo, en el que se utilizó de instrumento grupos focales y el método de la Investigación y Acción Participativa IAP. Los principales resultados obtenidos en la investigación fue que la Unión de Campesinos Organizados de la cuenca de San Dionisio a través de los años trascendidos desde su fundación, ha trabajado para lograr que los campesinos de Samulalí y El Jícaro tengan un desarrollo a escala humana tanto en la calidad de vida como en el entorno socio económico en el que éstos se desenvuelven, donde se detalla como principales hallazgos las potencialidades en Samulali la agricultura y el sentirse orgulloso de sus orígenes, en El Jícaro el cultivar y la ayuda mutua y carencias que presenta Samulalí es el financiamiento y la falta de armonía con el medio ambiente y en El Jícaro la falta de ganadería, el individualismo y la falta de participación. Así como también los niveles de resiliencia, en la que se clasificó la mejor y peor parcela. A la vez se brindaron estrategias para mejorar como pasar de rojo a amarillo, de amarillo a verde, tanto para la organización, como en la calidad de vida y así alcanzar la resiliencia óptima y prepararse para el cambio climático.

Estimation of dietary intake and content of lead and cadmium in infant cereals marketed in Spain

Lead and cadmium have become highly toxic metallic elements. There is an obvious 5 toxicological impact of these elements on infants since their intestinal absorption is 6 significantly higher than in adults, thus it is desirable to quantify lead and cadmium levels in 7 commonly consumed infant foods. Zeeman background correction, transversely heated 8 graphite furnace atomic absorption spectrometry, was used to determine both the lead and 9 cadmium content of 91 Spanish infant cereals. Cereals were assessed in terms of different 10 types, cereal predominant in formulation and whether it was obtained organically or 11 conventionally. Preliminary analysis revealed a noticeably higher content of lead and 12 cadmium (median, Q1-Q3) in organic cereals (n = 17, Pb: 26.07; 21.36-51.63; Cd: 18.52; 16.56-28.50 μg kg-1 13 ) in relation to conventional ones (n =74, Pb: 10.78; 6.43-19.33; Cd: 7.12; 4.40-11.77 μg kg-1 14 ). Three formulations exceeded European lead maximum levels. Added 15 ingredients (milk, cocoa, fruit and honey) to the cereal base provide lead enrichment. For 16 cadmium, this pattern was observed by cereal based on cocoa, but also the raw materials 17 contributed with a dilution phenomenon, decreasing the final cadmium concentration in infant 18 cereal. Apart from several organically produced cereals, lead content showed a narrow 19 variation, where gluten-free cereals provide lower cadmium content than formulations 20 containing gluten. Dietary intakes of both elements were assessed in comparison with the 21 reference intake values proposed by the EFSA Panel on Contaminants in the Food Chain. 22 Organic infant cereals based on honey and cocoa supplied the highest risk intakes of lead and 23 cadmium, respectively. In accordance with the actual state of knowledge on lead and 24 cadmium toxicity and attending to the upper limits calculated from risk intake values set by 25 EFSA, it seems prudent to call for a revision of both heavy metals content regulated by EC to set a maximum guideline values for infant cereal at 55 and 45 μg kg-1 26 , respectively

Survey of total mercury and arsenic content in infant cereals marketed in Spain and estimated dietary intake.

Due to the fact that infants and children are especially sensitive to mercury and arsenic 7 exposure, predominantly through diet, a strict control of the most widely consumed 8 infant foods, especially infant cereals, is of paramount importance. Levels of both total 9 mercury and arsenic in 91 different infant cereals from ten different manufacturers in 10 Spain were determined by flow injection adapted to cold vapor and hydride generation 11 atomic absorption spectrometry, respectively. Cereals were assessed in terms of the 12 different types, the predominating cereal in the formulation, the added ingredients, and 13 whether the cereal was organically or conventionally obtained. In general, the content of 14 toxic elements (median (Q1;Q3)) found in infant cereals based on conventionally obtained raw materials (n=74, Hg: 2.11 (0.42;4.58), As: 21.0 (9.4;50.9) μg·Kg-1 15 ) was 16 lower than in cereals produced by organic methods (n= 17, Hg: 5.48 (4.54;7.64), As: 96.3 (87.5;152.3) μg·Kg-1 17 ). Mercury content in infant cereals shows the higher values in 18 those formulations with ingredients susceptible to particulate contamination such as 19 gluten-free or cacao-based cereals. The highest arsenic content appears in the rice-based 20 cereals. The mercury and the inorganic arsenic dietary intakes for infants fed on the 21 infant cereals studied were assessed, taking into account the different stages of growth. 22 Organic infant cereals based on cocoa showed the highest risk intakes of mercury, very 23 close to exceeding the intake reference. Just the opposite, 95% of the organically 24 produced infant cereals and 70% of the conventional gluten-free infant cereals showed 25 an inadmissible risk of arsenic intake. Thus, it seems prudent to call for continued 26 efforts in standardizing routine quality control and in reducing arsenic levels in infant 27 cereals; in addition it is essential that relevant legislation be established and regulated 28 by EC regarding these two toxic elements

Surveillance of aflatoxin content in dairy cow feedstuff from Navarra (Spain)

Aflatoxins (B1, B2, G1 and G2) are produced by the fungi Aspergillus (A. flavus and A. parasiticus) in substrates used in cattle feed manufacturing. Aflatoxin M1 (AFM1) is a major metabolite of Aflatoxin B1 (AFB1) which may be present in milk from animals that consume contaminated feed. Levels of aflatoxins in 78 dairy cow feedstuff samples from 40 farms located in Navarra were determined by HPLC-FLD (High Performance Liquid Chromatography with fluorescence detection) and post-column derivatization. The influence of geographical location, season and type of feeding system on aflatoxin content was studied. The climatic profile of AFB1 pointed to spring as the season with the highest aflatoxin level (0.086 μg/kg), followed by winter and summer (0.075 and 0.030 μg/kg, respectively), and to a lesser degree, autumn (0.017 μg/kg). Moreover, wet and dry TMR (Total Mixed Ration) feeding systems (i.e. AFB1: 0.076 and 0.068 μg/kg; Aflatoxin G1 (AFG1): 0.050 and 0.011 μg/kg, respectively) showed a greater content of the analyzed aflatoxins in comparison with compound feed (i.e. AFB1: 0.039 μg/kg; AFG1: 0.007 μg/kg). The fact that the majority of the samples collected were based on compound feed shows that this type was preferred by most dairy farmers. The undetectable levels of aflatoxins in the organic homemade compound feedstuff are also worth mentioning. While none of the feedstuff samples contained amounts over those permitted under European legislation (5 μg/kg), the theoretical extrapolation of the carryover rate suggested in previously published experiments of AFB1 to AFM1 in secreted cow's milk predicts that only one of the feed samples studied had a positive aflatoxin level (53.4 ng/kg) higher than the legal limit for raw cow's milk

Documenting Decadal Spatial Changes in Seagrass and Acropora palmata Cover by Aerial Photography Analysis in Vieques, Puerto Rico: 1937-2000

Aerial photographs from 1937–2000 of Bahía Salina del Sur on vieques, Puerto Rico were analyzed to detect and describe spatial changes in the areal cover of sea-grass beds in Bahía Salina del Sur. The images were pre-processed to minimize noise and unsupervised classification was used to detect areas colonized by seagrass. The number of individual seagrass patches, direction, and characteristic of growth were quantified and described. Seagrass coverage increased by 85.8% over the 64-yr period and this increase was best described by a 2nd order polynomial function (r2 = 0.91). Between 1937 and 2000, the spatial expression of the seagrass patchiness went through discrete episodes characterized by expansion in the number and spatial extent of small patches followed by an increase in patch size and agglomeration of small patches to form large homogeneous areas. Patch growth was limited only by proximity to boundaries (i.e., coastline and reef structures) and a fluctuating physical environment. This study suggests that the overall increase in seagrass cover was linked to the synergy of hurricane impacts, decrease in grazers, and the protective geomorphology of Bahía Salina del Sur. Decreases in areal cover only occurred in concert with known anthropogenic impacts
