The present study seeks to analyze the publications of articles in the Scopus database on environmental issues carried out by a private university in Peru between 2013 and 2024 through a review of bibliometric indicators in which 200 papers were selected and analyzed. The search was conducted by affiliation. The variables analyzed are: author, year, citations, journal, index, language and topics. The results allow us to see that the years 2022 and 2023 had a higher number of publications (n=54 and 52), 2017 reports a higher average total of citations per article (n=78.57), the journal with the most publications is "Marine pollution bulletin" from Switzerland with a Q2, SJR = 0.83, with 20 articles, the most relevant authors are: Alfaro-Shigueto (n=37) and Mangel JC (n=34), the clusters identified show words that are not normally associated with the field of environmental sciences such as: human, clinical study and non-human, the article with the greatest impact is "Microplastics in the Antarctic marine system: An emerging area of research", the countries in which they are published the most are Switzerland, the Netherlands, the United Kingdom, Germany and the USA. The impact level are between Q1 and Q2 with SJR = 0.39 up to 2.15.

The objective of this master's thesis was to evaluate the impact of the program of a youth orchestra in the Province of Buenos Aires on the operability of working memory, executive functions and verbal working memory with standardized tests. A transectional study was carried out, where two groups of adolescent participants were compared, with and without musical training. Significant differences were found in favor of the group with musical training in the direct digit tests, reverse digit tests and the verbal comprehension subtests (similarities, vocabulary and comprehension), adding to the studies that affirm that musical training affects working memory verbal. No significant differences were found in the other tests. Finally, it is concluded that the youth orchestra program benefits some aspects of cognitive development in its participants.

The aim of this literature review is to examine and contrast four dietary patterns to evaluate their influence on Alzheimer's prevention. The need for this study arises from the lack of a comprehensive analysis definitively confirming the effectiveness of these diets in preventing this disease. An exhaustive literature review was conducted, including clinical trials, systematic reviews, meta-analyses, online books, guidelines, etc. However, only articles from studies, clinical trials, and controlled randomized trials were used for discussion. Exclusion criteria were: publication period of 5 years, articles published in indexed journals and in databases such as PubMed, COCHRANE, or Google Scholar, with an impact factor equal to or greater than 1.5. It has been evidenced that the four diets can offer benefits in Alzheimer's prevention. However, when selecting the most effective diet in Alzheimer's prevention, it is necessary to consider different types of nutritional approaches such as engaging in physical activity to improve cognitive decline.It has been demonstrated that the four investigated diets offer significant benefits in Alzheimer's prevention. Although the MIND diet emerges as a promising strategy, combining the benefits of the Mediterranean and DASH diets. Integrating this diet with practices such as mindfulness and physical activity is important to promote long-term brain health and reduce the risk of cognitive decline, thus maximizing Alzheimer's prevention.

Mexico has high rates of obesity and overweight, associated with chronic non-communicable diseases. The Mediterranean diet (DM) is useful to combat cardiovascular diseases, obesity, diabetes and metabolic syndrome. It is adaptable to the region, it can use its own foods with nutritional density similar to those of the Mediterranean. To evaluate the effect of a nutritional-educational intervention with the Mexicanized Mediterranean Diet (MMD) on anthropometry, glucose, lipids, insulin and interleukin 6 in overweight or obese adults in Mexico.  Longitudinal, prospective 6-week study. The DMM intervention group involved 16 subjects and the control group with the usual diet involved 13. All received nutritional education.  Anthropometric measurements and blood tests were taken.  In the group operated on with DMM, weight and BMI decreased in 75% of the participants, 62.50% reduced body fat percentage, 37.50% visceral fat, waist-to-height ratio (W/T) in the 32%, the waist/hip ratio (W/C) and the waist circumference in 25%.  Blood glucose decreased by 12.5%, insulin and HOMA decreased by 62.5%, glycated hemoglobin by 43.5%, triacylglycerols, cholesterol and LDL by 68.75%, VLDL by 62.5%, and the atherogenic index by 75%. , IL-6 by 100%, HDL increased by 50%. Adherence to the DMM improved with education. Discussion: The intervention with DMM achieved a reduction in weight and anthropometric-biochemical parameters in the population, reaffirming the effects of DM evidenced in scientific literature.
