Multifactorial Risk Reduction with Nutrition and Exercise Intervention: A Case Report and Review of Mechanisms
Authors: Danley Kelsey , Williams Sr. Kim A. , Brandon Margaret
Published: February 2023

The practice of cardiology by recent guidelines 1 includes assessment and management of cardiovascular risk with lifestyle first, followed by medications when lifestyle changes do not produce sufficient results or high risk is present. However, in clinical practice, the assessment of diet and exercise followed by meaningful intervention in these areas are not often emphasized by physicians, and implementation by patients is often lessthan optimal. In this case, there was a dramatic improvement in cardiovascular risk factors, including a profound degree of weight loss, along with a fall in systolic pressure, serum triglycerides, low-density lipoprotein cholesterol (LDL-C) and total cholesterol, possibly driven by the improvement in the microbiome induced by the patient’s exercise and dietary change to a whole food, plant-based diet. These remarkable changes represent an unusual response in terms of the degree, but not the direction, of improvement with exercise and a plant-based diet. The patient’s prospects of sustained weight loss and lifelong lower cardiovascular risk appear to be best with his adopted lifestyle changes, particularly the whole food, plant-based diet.

Published: February 2023

Este estudio tuvo por objetivo determinar si existen diferencias en el desempeño de la memoria de trabajo y representación espacial en niños y niñas mapuches rurales y no mapuche urbanos de la región de La Araucanía (Chile). Participaron 96 estudiantes entre 8 y 12 años (M = 10.33; DE = 1.02), quienes respondieron tareas de memoria de trabajo y de representación espacial en formato verbal y no verbal. Se utilizó un análisis multivariado de la covarianza (MANCOVA), controlando el efecto de la edad y el sexo. Los resultados evidencian que los participantes mapuche puntuaron más bajo que sus pares no mapuche en memoria de trabajo verbal, y se encontraron diferencias marginalmente significativas en memoria de trabajo no verbal. En la representación espacial verbal no se obtuvieron diferencias entre los grupos y en representación espacial no verbal los niños mapuches obtuvieron un desempeño significativamente más alto que sus pares no mapuche. Los niños no mapuche tienen un mayor desempeño en tareas verbales, mientras que niños mapuche obtienen desempeños similares o más altos en tareas no verbales. Se discute la relevancia de la validez ecológica desde el paradigma de la cognición situada.

The fungus Fusarium verticillioides produces fumonisins (FB1 and FB2), characterized by being the most frequently produced molecular forms and with greater toxicity. Fumonisin contamination is responsible for substantial losses during the meat production chain, so the safe levels of these compounds must be determined. The study was directed to establish safe levels of FB1 in poultry production; for this purpose, were used COBB 500® birds on experimental lots of infected corn during the 2015/2016 season in Brazil. The experimental group included 160 animals, divided into two groups: The T1 without fumonisin in the diet (control); and the T2 group in which corn was contaminated with 2.78 μg/g of fumonisin FB1. Histopathological effects of liver, heart, and small intestine, and zootechnical parameters were measured in birds treated. We found that there were no significant differences between the birds treated and untreated after 21 days of exposure to each treatment; F-values > P-values (P<0,05) for feed intake and weekly weight gain. Taken together, our data showed that the concentration evaluated is safe in poultry and will contribute to the design of future clinical studies.

Published: February 2023

The characterization of production systems is important to determine limitations and potentialities that allow their management. This type of diagnosis has not been carried out in the study region; therefore, there is no information on cocoa-based agroforestry systems. Therefore, traditional cocoa farms in the municipality of Los Andes, department of Nariño (Colombia), were social and economically characterized. Basic information was reviewed and a semi-structured survey was applied to a stratified random sample of 60 cocoa farmers. Eighteen qualitative and 20 quantitative variables were analyzed simultaneously with multiple correspondence analysis (MCA) and principal components analysis (PCA). In the PCA, five components explained 58.7% of the variability. The variables with the highest contribution were farm area, income from cocoa yields, income from agricultural production other than cocoa, and family labor. In the MCA, 11 components explained 58.43% of the variability. The most important components were farmers' schooling, transport type, loans, marketing, technical assistance, gender, land tenure, production systems, roads, and domestic animals. Finally, topographic and climatic conditions, inadequate roads and marketing of cocoa and the low adoption of technologies limit the competitiveness of the cocoa farms, hence the need to create favorable conditions to enhance the potential of cocoa agroforests.

The Cenozoic volcanism, which has been active in the territory of Mongolia since the beginning of the last century, has attracted the attention of Central Asian researchers. The purpose of this study is to analyze the geological research materials of the previous study and to determine the morphological origin and morphology of Shiliin Bogd volcano as the key representative of Cenozoic volcanism.  In general, due to the lava flow of basic composition, several types of geomorphological forms have been identified, and the identification of the type of dominant distribution is associated with a relation with origin problem that has not been encountered in our country before, and because of the current importance, the selection of the Shiliin Bogd volcano in Dariganga Plateau becomes important. The morphometric analyses were performed in-field measurements and previous studies, also highlighted the faults in satellite and other images using the morpho-structure method in order to depict the geomorphology of the Shiliin Bogd volcano. By comparing the results of the morphometric analysis, the Shiliin Bogd volcano morphological type was determined and a schematic diagram of the volcano's origin was developed. A large lava flow of fundamental composition flowed along to the large faults that stretched from the northeast to the southwest of the Shiliin Bogd volcano, which resulted in the current morphological forms of Shiliin Bogd and other volcanoes. The lava flow had a flow rate of less than 50% SiO2, which led to the creation of a Lava Plato. The morphological formations of lava cones, which are semicircular and basal in composition, with the average slope of the Shiliin Bogd volcano crater in 410, depth 63 meters and crater average diameter 302 meters, have been compared with morphology of other volcanoes by morphometric analysis. Based on the researchers' research data, the age of the trap of Shiliin Bogd volcano can be traced to the late Quaternary age, possibly to the Holocene age. Further details of the age of the basalt rock need to be precise.

Although many studies investigated the spatial distribution, duration and frequency of dust storm in Mongolia, there are a few studies were undertaken it in terms of physical process that underpinned the current study on the subject. The study examines whether it is possible to acquire the distribution of dust storms in a relatively simple way by estimating the atmospheric stability during a dust storm. In order to achieve the main purpose of the study, the atmospheric stability parameters such as Brunt-Vaisala frequency (N), Gradient Richardson Number (Ri), and Eady Growth Rate (σ_E) were evaluated on 3 different cases of heavy dust storms which are occurred from March to May 2020, covered almost all over Mongolia, using reanalysis data produced by the European Centre for Medium-Range Weather Forecasts and radiosonde data from “Dalanzadgad” an aerological station in Dalanzadgad, Umnugovi. Differential equations of N, Ri, and σ_E are solved using the finite difference method. The results of the study revealed that both Ri and σ_E stability parameters can be identified well the distribution of dust storm, while a linear relationship between a dust storm and N as well as the buoyancy component of Ri was not found. In addition, in the study, a simplified method to compute the Ri parameter based on power function was acquired by the wind shear. It was difficult to make statistical analyses in the results of the study based on few cases between March and May in 2020. Therefore, it is necessary to consider more cases in the future, to undertake statistical analysis.

This study aims to study international tourists’ perceptions towards the quality of tourism service provided at two tourist sites in Mongolia and to measure tourist satisfaction by examining the impact of the quality of tourism products on overall tourist satisfaction moderated by destination image. In this research, six hypotheses were developed for the purpose of the research model. The empirical data were collected from the international tourists via a questionnaire that yielded 230 usable surveys at the “Chinggis Khaan Statue Complex” and “Tumen EkhEnsemle” in Ulaanbaatar, Mongolia. The data was analyzed by using regression analysis to determine the relationship between service quality and tourist satisfaction. In addition, a moderating effect of destination image between service quality and tourist satisfaction was verified by regression analysis. The findings confirmed that quality of service directly impacted tourist satisfaction throughout destination facilities. Moreover, the monetary advantages and convenience advantages of the quality of tourism service had a positive impact on tourist satisfaction. On the contrary, safety and security were more concerned construct which had a negative impact on tourists’ satisfaction. Study findings supported the evidence that higher satisfaction reflects positively on the high revisit intention. The effect of convenience on tourist satisfaction was moderated differently by the level of a natural and cultural image. The findings of this research support that service quality plays an important role in tourism and it is a crucial factor to increase the level of tourist satisfaction. Moreover, the research result provided theoretical and managerial implications based on the findings to tourism practitioners by presenting recommendations for further studies.

Судалгааны үр дүнгүүдийг нэгтгэн үзэхэд Өгий нуурын талбай сүүлийн 30 орчим жилийн хугацаанд аялал жуулчлалын зориулалттай барилга байгууламж барих, шинээр худаг ухах, загасчлалын нөлөө,авто замуудын замбараагүй сүлжээ, мал аж ахуй эрхлэлттэй холбоотой хүний хүчин зүйлсээс шалтгаалж газрын гадаргад эвдрэл, доройтол илэрч, ургамлын бүрхэвчийн хэмжээ багассан зүй тогтол ажиглагдаж байна. Өгий нуур орчимд сүүлийн 30 жилд 136.2 км замын сүлжээ үүссэн байна. Судалгааны талбайд 2004-2019 оны хугацаанд 7 барилга 10.3 га талбайгаар тэлж, түүнтэй ойролцоо 70 гаруй га талбайд антропоген нөлөөллөөр газрын гадаргад өөрчлөлт орсон байна. Энэхүү судалгаа нь аялал жуулчлалын зорих газрыг зөв зохисгүй байгальд ээлгүй ашиглалтаас үүдэх үр дагаврыг тодорхойлсноороо ач холбогдолтой юм.

Data on the origin and morphology of lake depressions in Mongolia is poor and only 2 percent of total studies. The morphological patterns of the lake depressions caused by volcanic activity have not been well studied in Mongolia. The morphometric indicators of Khorgo volcanic lava plateau, its effect on the morphological changes of the lake depression, and the relationship between them are not studied in detail. The Khorgo volcanic lava is analyzed to clarify how it formed and compare it to the origin of the neighbouring Terkhiin Tsagaan Lake depression. This paper is defined the effect of Khorgo volcanic lava plateau on the origin of the Terkhiin Tsagaan Lake depression, based on morphometric analysis, remote sensing and geological mapping. Also study is checked by field measurements as identifying fault lengths, locations and morphology. Upon the Khorgo volcano activation, the valley of the Terkh River was dammed by a lava plateau. Lava damming formed the Terkhiin Tsagaan Lake depression, blocking the Terkh River valley. Another evidence is the age of the lava plateau and lake sediment. Terkhiin Tsagaan Lake area was three times larger than it is now (9000 years ago), comparing the terraces on the shoreline of the lake. The lake water outflows via the Suman River. The Suman River diversion has created a large canyon along fault. Changes in the water volume of Terkhiin Tsagaan Lake and the erosion of the Suman Gol canyon are inversely related.  This study is concerned that the effect of the youngest volcano in Central Asia is achieved a role in the development of lake depression, and presents a basis for integrating morphometric analysis to define the main phases of volcanic activity and lake depression evolution. Current lake area and volume is under influences of climate and environmental changes and human activities.

Surface water resources and flow regime of the river are dependent on climate, physical geography, soil condition, geology and hydrogeological conditions of the basin. These factors vary spatially and temporally and affect the runoff. To study the flow regime of the river including snowmelt and rainfall flow is crucial information for flood mitigation, control, water harvesting, hydro construction planning, dam and other hydrologic systems, etc.  Therefore, we attempted to investigate the flow regime and its changes of the Taats river which is located in the Asian internal drainage basin in this study. The study was conducted using the daily runoff, precipitation and air temperature data for the period of 1975-2019. In addition, the Mann-Kendall test was applied to detect trend analysis for the annual runoff and maximum flow of the snowmelt and rainfall events. The probability of the maximum runoff of the snowmelt was estimated through the Gringorten method. The results show that the mean annual runoff and snowmelt flow decreased and rainfall flow has increased insignificantly in the study period.  However, it was observed the changes in the timing of the snowmelt runoff shifted toward later in the year 1975-1990, earlier in the year 1991-2003 and on average in the period of 2004-2019. The maximum runoff of the snowmelt and rainfall is estimated at 13.2 m3/s and 275 м3/c, respectively in the 100 years.

The main objectives of this study were to use the statistical model (ANUSPLIN) to calculate the updated norms Mongolia of air temperature and precipitation (average for 1991-2020 according to the World Meteorological Organization) with high spatial accuracy for any grid, and to perform objective analysis in observation data. GTOPO30 (global digital elevation model, DEM) elevation grid data with 30-arc seconds (1 km) accuracy for estimating the mountain and orographic conditions of Mongolia, and monthly climate data of 137 meteorological stations of the National Agency of Meteorological and Environment of Mongolia (NAMEM), as well as monthly data of 3 automatic weather stations for glacial melting and accumulation research, were used to generate a series of data from 1991 to 2020 using climate statistical processing and comparison methods (linear regression equations). The data were used as peripheral and initial condition data for the statistical model (ANUSPLIN). The average spatial resolution of the data is ~ 0.75 ° or ~ 83.2 km for 137 meteorological stations, and ~ 0.87 ° or ~ 96.2 km for 3 automatic meteorological stations for ice melting and accumulation research. Hence, it can be considered that the hydro-meteorological and environmental research stations of Mongolia are relatively distributed sparsely. As a result of the statistical downscaling analysis, monthly air temperature and precipitation norms of Mongolia as an average of 1991-2020 were calculated for each grid with a spatial resolution of 0.0125° × 0.0125° (~ 1.4 × 1.4 km). The spatial correlation coefficients (SPC) were 0.97-1.00 and 0.88-1.00 for air temperature and precipitation, respectively, while the mean square error (DCA) was 0.24 °C to 1.03 °C for temperature and 0.02 mm to 3.61 mm for precipitation. For spatial average, the air temperature from the model was warmer by 1.1-1.4 °C in winter (December to January) and 0.2-0.6 °C in spring and autumn (March to May, and September to November) than for observation data, while it was very similar for the summer (June-August). But model precipitation was reduced by 0.5-2.9 mm during the warm season (May-October) than observation data. The monthly correlation coefficients between the statistical model and observation data were 99% or higher. Therefore, this high-resolution spatial data for air temperature and precipitation norms of Mongolia for grid points calculated using the statistical model ANUSPLIN can be used as fundamental data for various scientific studies such as environment, agriculture and biology.

For the last 90 years, approximately 100 research magazines have been published in each scientific sector of Mongolia in the Mongolian, Russian and English languages. But there is not any published research which clarifies development trends of each sector involving a review and analysis in the scientific journal of any specific area or sector in Mongolia. I have undertaken a review and analysis of this research using a comparative analysis method. In this article, the research published in the journal of Geographic Issues over the last 20 years was compared. This involved the review of articles, the involvement of authors, the similarities and differences in the field of scientific content, and the development trends of research. This was all clarified. The results showed that except for Mongolian researchers, Russian, German, British, American and Japanese researchers published their articles in this journal. Within the period the research involved 168 researchers who participated as a first author and 400 researchers as other authors in the publication of a total of 359 articles in developing the journal of Geographical Issues. Regarding the scope, more than 10 articles were published in the areas of service geography, meteorology and climate science, land relations, urban geography, environmental science, hydrology, agricultural geography, recreational geography, remote sensing and geomorphological studies. Baseline study materials of physics and social geography, which are the main sectors of geography, have comparatively been published rarely. The main trend of the magazine is inter-sectoral research work based on physical geography and socio-economic geography. It was a key principle of this magazine to publish this research by filtering them in an ethical and fair manner.

Tourism is one of the sectors most affected by the Covid-19 pandemic, impacting economies, livelihoods, public services and opportunities on all continents. International tourism has collapsed due to travel restrictions, closure of public places including major tourist attractions, and travel warnings of governments against travel and movement of people. Due to the impact of pandemic on travel freedom and tourists’ confidence, many destinations and governments have paid more focuses on domestic tourism and short haul nearby markets to ensure a recovery of tourism This research aims to explore the potential of domestic tourism as a means to revitalize the tourism industry from the perspectives of local tourism stakeholders. Interview data were collected and focused on domestic travel behavior, motivation, places of interest, travel preferences, and willingness to travel within Mongolia. Data were collected using structured, open-ended interview questions through key-informant interviews to twelve respondents from tourism stakeholders, nine from the local tour operators, and two from the tourist ger camp operators, and one from online tour agency. Data collection was carried in December 2021. The findings reveal that domestic tourism has the potential to revive and stabilize the tourism industry. A high percentage of respondents indicated that Mongolians have desire to travel domestically and being motivated by attractive natural scenery and resources for example, river, lakes, springs, and forest, as well as tour packages at discounted prices. COVID-19 has impacted tourist behavior and attitudes towards travelling, and people prefer to travel domestically rather than overseas. Furthermore, tourism stakeholders acknowledged the potential to revive the tourism industry via domestic tourism. Despite this, declarations of health, safety issues, flight availability, marketing communication methods, variety of tour activities, travel planning, and decision-making behaviors of Mongolians are key barriers to conducting domestic tourism in Mongolia.
