Down syndrome (DS) is related to diseases like congenital heart disease, obstructive sleep apnea, obesity and overweight. Studies focused on DS associated with obesity and overweight are still scarce. The main objective of this work was to analyze the relationship between dietary intervention, physical exercise and body composition, in DS with overweight and obesity. This review is based on the PRISMA guidelines (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Selection criteria for this analysis were: publications between January 1997 and December 2019; DS individuals with overweight and obesity; clinical trials using dietary intervention and physical exercise paying attention to changes in body composition. Selected clinical trials were focused on an exclusive intervention based on physical exercise. The anthropometric measures analyzed were body fat, BMI, waist circumference, body weight and fat free mass. The main conclusion is that prescribing structured physical exercise intervention may be related to a greater variation in body composition. Despite limited number of clinical trials analyzed, it can be assumed that the reported studies have not achieved optimal results and that the design of future clinical trials should be improved. Some guidelines are proposed to contribute to the improvement of knowledge in this field., Competing Interests: The authors report no conflict of interest.

(1) Objective: to establish practical guidance for the design of future clinical trials in MS (metabolic syndrome) patients aged 18 and older, based on a systematic review of randomized clinical trials connecting diet, physical exercise and changes in body composition. (2) Method: this systematic review of randomized clinical trials (RCT) is based on the guidelines recommended by PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Criteria of selection: ≥18 years of age; patients diagnosed with MS; intervention programs including diet, physical exercise and/or modifications in the style of life as treatment, as well as the magnitude of changes in body composition (BC); randomized clinical trial published between 2004 and 2018. (3) Results: the multidisciplinary interventions describe major changes in BC, and the recurring pattern in these clinical trials is an energy reduction and control in the percentage of intake of macronutrients along with the performance of regularly structured exercise; the most analyzed parameter was waist circumference (88.9% of the trials), followed by body weight (85.2%), BMI (77.8%) and body fat (55.6%). (4) Conclusions: The analysis of the information here reported sheds light for the design of future clinical trials in adults with MS. The best anthropometric parameters and units of measurement to monitor the interventions are related to dietary and physical exercise interventions. A list of practical advice that is easy to implement in daily practice in consultation is here proposed in order to guarantee the best results in changes of body composition., Competing Interests: The authors report no conflict of interest.

Objective: To record which interventions produce the greatest variations in body composition in patients ≤19 years old with metabolic syndrome (MS)., Method: search dates between 2005 and 2017 in peer reviewed journals, following the PRISMA method (Preferred Reporting Items for Systematic reviews and Meta-Analyses). The selection criteria were: diagnostic for MS or at least a criterion for diagnosis; randomized clinical trials, ≤19 years of age; intervention programs that use diet and/or exercise as a tool (interventions showing an interest in body composition)., Results: 1781 clinical trials were identified under these criteria but only 0.51% were included. The most frequent characteristics of the selected clinical trials were that they used multidisciplinary interventions and were carried out in America. The most utilized parameters were BMI (body mass index) in kg/m² and BW (body weight) in kg., Conclusions: Most of the clinical trials included had been diagnosed through at least 2 diagnostic criteria for MS. Multidisciplinary interventions obtained greater changes in body composition in patients with MS. This change was especially prevalent in the combinations of dietary interventions and physical exercise. It is proposed to follow the guidelines proposed for patients who are overweight, obese, or have diabetes type 2, and extrapolate these strategies as recommendations for future clinical trials designed for patients with MS.

Carotenoids are among the most abundant natural pigments available in nature. These pigments have received considerable attention because of their biotechnological applications and, more importantly, due to their potential beneficial uses in human healthcare, food processing, pharmaceuticals and cosmetics. These bioactive compounds are in high demand throughout the world; Europe and the USA are the markets where the demand for carotenoids is the highest. The in vitro synthesis of carotenoids has sustained their large-scale production so far. However, the emerging modern standards for a healthy lifestyle and environment-friendly practices have given rise to a search for natural biocompounds as alternatives to synthetic ones. Therefore, nowadays, biomass (vegetables, fruits, yeast and microorganisms) is being used to obtain naturally-available carotenoids with high antioxidant capacity and strong color, on a large scale. This is an alternative to the in vitro synthesis of carotenoids, which is expensive and generates a large number of residues, and the compounds synthesized are sometimes not active biologically. In this context, marine biomass has recently emerged as a natural source for both common and uncommon valuable carotenoids. Besides, the cultivation of marine microorganisms, as well as the downstream processes, which are used to isolate the carotenoids from these microorganisms, offer several advantages over the other approaches that have been explored previously. This review summarizes the general properties of the most-abundant carotenoids produced by marine microorganisms, focusing on the genuine/rare carotenoids that exhibit interesting features useful for potential applications in biotechnology, pharmaceuticals, cosmetics and medicine.

This review summarizes recent knowledge about the use of the amino acid l-Cysteine (l-Cys) through diet, nutritional supplements or drugs with the aim to improve human health or treat certain diseases. Three databases (PubMed, Scopus, and Web of Science) and different keywords have been used to create a database of documents published between 1950 and 2017 in scientific journals in English or Spanish. A total of 60,885 primary publications were ultimately selected to compile accurate information about the use of l-Cys in medicine and nutritional therapies and to identify the reported benefits of l-Cys on human health. The number of publications about the use of l-Cys for these purposes has increased significantly during the last two decades. This increase seems to be closely related to the rise of nutraceutical industries and personalized medicine. The main evidence reporting benefits of l-Cys usage is summarized. However, the lack of accurate information and studies based on clinical trials hampers consensus among authors. Thus, the debate about the role and effectiveness of supplements/drugs containing l-Cys is still open., Competing Interests: The authors report no conflict of interest.

Unlabelled: Objetive: to determine the adequate intake of macronutrients to improve the nutritional status of women athletes and their sports performance., Methods: a search was performed in four databases: EBSCO, Proquest, Pubmed and OvidSP, using the keywords "protein intake" AND "athletes", "endurance athletes" AND "nutrition"., Selection Criteria: original articles about protein intake in female athletes, published between 2009 and 2014, and whose source are indexed scientific journals., Results: 722 articles were identified, of which only 1.4% were considered to be included. 100% were completed clinical trials and published abroad, 50% in the US. 20% were exclusive studies of female athletes and 80% included men and women in the sample. In 70% of studies female athletes presented energy deficiencies; in protein intake, 70% met the dietary recommendations; carbohydrate intake was inadequate in 90% of clinical trials and in 50% of cases women had a high intake of fat., Conclusion: there is lack about nutrition in female athletes in Europe and internationally. Female athletes consume less energy and macronutrients that male athletes. There is no consensus on the recommended protein range and there are differences in consumption depending on the type of exercise being performed. It is recommended to carry out an agreement between scientific institutions about energy intake and macronutrient in sport, with particular emphasis on women., (Copyright AULA MEDICA EDICIONES 2014.

Unlabelled: %WL: percentage of weight loss; % FL: percentage of fat loss., Objective: to describe the management methodology of a qualitative and quantitative dietary treatment for overweight and obesity., Method: 4,625 consultations were conducted with 616 overweight and obese patients over the age of 25 in the south-east of Spain between 2006-12. A balanced, low-calorie, qualitative and quantitative diet based on locally grown food was employed. The weight loss and maintenance dietary treatment methodology is described, as are the units of measurement considered suitable for the expression of successful weight loss; a new vision of individualised counselling and multidisciplinary treatment., Results: 80% of patients obtained a % FL ≥ 5% (22.6±11.8-11.2±7.4), and attended appointments for more than a month and a half., Conclusion: the dietary treatment methodology is described; units of measurement are recommended for use in consultations and in clinical trial publications, creating a precedent with a degree of evidence on how to determine successful weight loss; it is recommended to measure hip and waist perimeters and incorporate a study of body image; a new vision of individualised assessment and advanced multidisciplinary care is presented, independent of age, pregnancy and physical disabilities. The health care professional's position should be seen as that of the person responsible for determining which techniques might be most effective in such loss., (Copyright AULA MEDICA EDICIONES 2014.

Objective: to identify what effect causes enteral nutrition on nutritional status of cancer., Method: a search was performed using the keywords "Cancer" AND "Enteral Nutrition" AND "Supplementation" in four document databases: Pubmed, EBSCO, ProQuest, and Web of Science., Inclusion Criteria: age of the sample, major than 18 years; submitted to surgery for cancer; that the intervention program was including diet and employment or not of nutritional Supplementation; clinical trials published between January 2004 and December 2014, in scientific journals indexed., Results: we analyzed 660 articles, of which only 2% has been included. 58% of intervention programs are applied outside Spain; 84% of the interventions was carried out in a hospitable ambient; 58% of the sample is formed by adults older than 54 years; 33% of the interventions were multidisciplinary and its duration ranges between 1 and 4 years., Discussion: we found just a few national interventions in cancer participants and there two types of interventions: by exclusive polymeric enteral formula or mixed with immunonutrition., Conclusions: enteral nutrition shows against the parenteral and its introduction at an early stage, it helps to improve nutritional status of the patient; polymeric formulas next immunonutrition, it helps to reduce the time of hospitalization; the analytical parameters are shown as a measurement pattern when assessing the improvement in nutritional status in cancer. It is recommended to increase the research in this field, especially in children., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

Purposes: assessing the magnitude of the effects of green tea in subjects that do exercise., Methodology: a search was been carried out with key words "green tea" AND "exercise" in four documentary databases: Pubmed, EBSCOHOST, OvidSP and Proquest., Inclusion Criteria: adult age of the sample (18-65 years, based on WHO), and the consumption of a quantified amount of green tea or substitutes, along with doing physical exercise measurable in intensity, in clinical tests published between January 2010 and December 2014, whose source were indexed scientific journals., Results: 260 articles were analyzed, of which 13 items were selected. 69% are studies with a designed workout, and 92% have included an exercise test to assess parameters. 77% fluctuate between 20-40 years and sample size between 9 and 36 subjects. 69% are long length. GTE has been the most used substitute (38%). 92% of studies have obtained some improvement and 92% of them, were significantly statistic. Interpretation of results: little homogeneity has been found in results in the analysis of results expression. Sample size is limited. There is a wide range of GTE substitutes and diversity of doses and exercise done. It cannot be possible to establish a dose, dosage and physical activity recommended., Conclusions: green tea gives us a wide variety of benefits in combination with physical exercise. There is a little evidence about quality. It cannot be possible to establish specific recommendations for obtaining benefits., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

Unlabelled: WL%: percentage of weight loss; % FL: percentage fat loss; PNLWF: patients who lose weight or fat; PLWF: patients who lose weight and fat., Objective: assess whether the% WL and FL% in the dietary treatment was affected by gender, age, BMI and assistance to the query., Method: 4,700 consultations, 670 patients (BMI ≥25), in the south-east of Spain (2006-12). Balanced and hypo-caloric diet was used. Two types of patients: PNLWF and PLWF (91.9%)., Results: in PLWF, men and those attending a greater number of occasions to the consultation have shown a greater loss against women (%FL: 23.0 vs 14.3%, p = 0.000; %WL: 7.7 vs 6.6%, p = 0.020), and those who attend less frequently (%FL: 19.1 vs 7.3%, p = 0.000; %WL: 7.8 vs 2.9%, p = 0.000). Multinomial regression analysis (PNLWF / PLWF) indicates that only attend more than one and a half to the consultation is a factor in the loss, OR 8.3 (IC 95% 4.5-15.1; p = 0.000)., Conclusion: the body fat measurement provides additional information lost weight; Most patients attend more than six weeks, obtained a high %FL; attendance is a predictor of loss; the %FL indicates that the dietary management plays a major role in the resolution of this pathology; It is recommended to design practical schemes of action process nutritionists according to the IMCI and variable., (Copyright AULA MEDICA EDICIONES 2014.

Concepts: %WL: Percentage of weight loss; %FL: Percentage of fat loss., Objective: evaluate which unit of measurement for weight loss could determine the success or failure of dietary treatment for overweight and obesity., Method: 4,625 consultations carried out on 616 patients in the southeast of Spain from 2006 to 2012. All of the patients were over 25 years of age and suffered from overweight or obesity. The consultations were carried out every fortnight, using the Mediterranean or low-calorie diet. The patients were divided into four groups according to their %WL and %FL., Results: most of the sample consisted of: women; participants between 25-45 years of age; attended consultations for over a month and a half; obese. 80% of the patients obtained a %FL ≥ 5% (15.5 } 12.8). The groups with a higher %FL obtained significant differences in weight loss (22.6 vs 11.2%, p = 0.000). The multinomial analysis shows significant differences between the groups with the highest %FL and the lowest %WL and %FL: sex (p = 0.006 vs p = 0.005), BMI (p = 0.010 vs p = 0.003) and attendance (p = 0.000 vs p = 0.000)., Conclusion: the patients who lost < 5% of fat had higher initial parameters (percentage of weight and fat); most of the sample lost ≥ 5% of fat. This means that the method of personalised dietary treatment results in a high fat loss; fat is an indicator of the quality loss obtained., Recommendations: use the measurement of fat as a complementary unit of measurement to weight loss; establish a limit of 5% to evaluate such loss; and increase this type of research in any method of weight loss., (Copyright AULA MEDICA EDICIONES 2014.

Objective: Observation of weight loss and the maximum time that individualized dietary treatment qualitative and quantitative is shown to be effective., Method: 4625 consultations were conducted with 616 patients over 25 years old, in the nutrition consultation, using the qualitative and quantitative individualized dietary treatment. As a result we controlled the weight loss, the fat and the quality and variability of the loss, monthly according to sex, age and BMI in an urban area of southeastern Spain., Results and Discussion: A low level of abandonment was proved in men, patients older than 45 years old compared to obese showed a higher degree. The quality of the loss was greater in men under 45 years old, overweight patients, however, more research is needed in this area. Measuring the waist and hips has led to an increasing interest in measuring indicators of body fat., Conclusion: The individualized dietary treatment has been proved to be effective for six months and then a multidisciplinary mode of this treatment is recommended. The use of new ways to assess weight loss is proposed taking into consideration the quality and variability of loss, regardless of the treatment used., (Copyright AULA MEDICA EDICIONES 2014.

Introduction: In Spain, nearly 14% of the population is diabetic, 95% corresponds to Type 2 Diabetes Mellitus patients. Poor glycemic control increases morbidity and mortality. There are three pillars in the treatment of type 2 diabetes: diet, medication and exercise. However, the potential for prescribing exercise training has not been fully exploited., Objective: To analyze the effect of different exercise modalities (AE, RT, Combo, HIIT) on glycemic control in patients with type 2 diabetes mellitus., Methods: The reserch was performed in 3 electronic databases (Pubmed, Scopus and Proquest), including publications from 2011 to the present, publications undertaking interventions with AE, RT, Combo or HIIT, and those that measured capillary glucose, CGMS or HbA1c., Results: Of the 386 articles found, 14 met the inclusion criteria. These items were classified according to exercise intervention modality (AE, RT, Combo, HIIT) and whether glycemic control was measured as a result of continued training or 24-48h post-workout., Conclusions: EA, RT, Combo and HIIT show efficacy in glycemic control in both the continuous training and 24-48h post-training. To achieve certain benefits in glycemic control, prescribing a structured frequency, volume and intensity training is required. Combo is the modality that gets better results through continued training., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

Objective: It shows a new study that examines if the anthropometric measurements can be used to classify the muscle dysmorphia (MD), in gymnasts who attend fitness room., Methodology: Gymnasts were analyzed several weights rooms of Alicante (urban area of southeastern Spain), where the measurements were 141 males aged between 18-45 years, aiming to enhance their muscle mass. We had in mind the calculation of BMI (kg/m2), the somatotype (endomorphy, mesomorphy and ectomorphy) and have been classified potential cases of muscle dysmorphia, using the Muscle appareance satisfaction escale., Results: The sample was composed of 68 normoweight; 66 overweight and 7 obese, classified as MD in a 25.0% the normoweight, 33.3% overweight and 85.7% of the obese (p=0.004 ). On the somatotype, the only component that presents differences between non-MD and MD is mesomorphy (p=0.024)., Conclusion: Muscle dysmorphia is a concept clearly difficult psychological diagnosable using anthropometric measures. Mesomorphy is the only measure that is increased in the MD, and may be a parameter to aid in the diagnosis and follow-up to the MD. In addition, the risk of developing MD is increase with the degree of obesity., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

Introduction: There are different parameters to express the loss of weight in the treatment of overweight and obesity: absolute loss, percentage of loss, decrease in BMI, etc., Objective: To determine the magnitudes more used in the bibliography in order to establish criteria for uniformity in the expression of those results., Methods: a systematic review of the last five years has made at Proquest, CINHAL, Scopus, with descriptors "body fat distribution" and "diet" and "diet, reducing" and "weight loss". Articles published in English, French and Spanish were selected. Inclusion criteria were used: articles only dietary treatment of overweight in humans, and exclusion criteria: not dietary treatments, metabolic diseases, less than 50 patients and less than 8 weeks of treatment. Title, summary, methodology, results and discussion have been analysed by two researchers independently., Results and Discussion: 854 items found, only 61 met the criteria. These were grouped into 5 subgroups, as they expressed the weight loss (weight or fat loss in kg; weight and fat loss in kg; weight or fat loss in %; weight loss in % and fat loss in kg or vice versa; weight and far loss in%). The results show a lack of homogeneity in the loss, being the percentage the most used expression., Conclusions: There is great heterogeneity in the expression of results of the treatments for weight loss; the diet is one of the least used tools; the analysis of clinical trials of intervention reflects a high quality in subjects older than 18 years, highlighting the lack of this type of research lines in children under 18 years. Therefore, it should standardize the magnitudes of expression of the success of these treatments and increase the lines of research on this topic., (Copyright AULA MEDICA EDICIONES 2014.
