Microencapsulation of vitamins: A review and meta-analysis of coating materials, release and food fortification.

Vitamins are responsible for providing biological properties to the human body; however, their instability under certain environmental conditions limits their utilization in the food industry. The objective was to conduct a systematic review on the use of biopolymers and lipid bases in microencapsulation processes, assessing their impact on the stability, controlled release, and viability of fortified foods with microencapsulated vitamins. The literature search was conducted between the years 2013-2023, gathering information from databases such as Scopus, PubMed, Web of Science and publishers including Taylor & Francis, Elsevier, Springer and MDPI; a total of 49 articles were compiled The results were classified according to the microencapsulation method, considering the following information: core, coating material, solvent, formulation, process conditions, particle size, efficiency, yield, bioavailability, bioaccessibility, in vitro release, correlation coefficient and references. It has been evidenced that gums are the most frequently employed coatings in the protection of vitamins (14.04%), followed by alginate (10.53%), modified chitosan (9.65%), whey protein (8.77%), lipid bases (8.77%), chitosan (7.89%), modified starch (7.89%), starch (7.02%), gelatin (6.14%), maltodextrin (5.26%), zein (3.51%), pectin (2.63%) and other materials (7.89%). The factors influencing the release of vitamins include pH, modification of the coating material and crosslinking agents; additionally, it was determined that the most fitting mathematical model for release values is Weibull, followed by Zero Order, Higuchi and Korsmeyer-Peppas; finally, foods commonly fortified with microencapsulated vitamins were described, with yogurt, bakery products and gummy candies being notable examples.

Características sociodemográficas, económicas y de salud de los beneficiarios de los Servicios Educacionales Complementarios Básicos / Sociodemographic, economic and health-related characteristics of the beneficiaries of Basic Complementary Educational Services

Introducción: La nueva Ley Universitaria 30220 permite mejorar las condiciones básicas de calidad universitaria en Perú, y es pertinente conocer las condiciones del estudiante y su procedencia para la mejora continua de su progreso académico. Objetivo: Determinar las características sociodemográficas, económicas y de salud de beneficiarios de los servicios educacionales complementarios básicos de la Universidad Nacional de Frontera, Sullana Perú. Métodos: Se trata de un estudio descriptivo. Se revisaron los cuestionarios socioeconómicos, familiares y de salud de los beneficiarios. La población fue censal y ascendió a 1285 estudiantes. Resultados: Del total de estudiantes, 64 por ciento fueron mujeres y 35 por ciento hombres; asimismo, se determinó un elevado porcentaje de estudiantes con servicio de agua por horas, y se observó que algunos trabajaban en ocupaciones de ventas, en trabajo independiente y como mototaxistas. También se determinó que la mayoría de los estudiantes percibían un sueldo mensual entre 250-500 soles. En cuanto a la vacunación, se determinó que los estudiantes se colocaron la vacuna antitetánica, la vacuna contra el sarampión, la vacuna contra la hepatitis B, y la vacuna contra el virus del papiloma humano. Además, se halló un bajo porcentaje de estudiantes con asma, con algún tipo de alergia, y con padecimiento de alguna discapacidad, depresión y abuso sexual. Conclusiones: El servicio complementario de salud que brinda la universidad es pertinente para reducir riesgos de deserción por motivos de salud durante el pregrado. Aunque se necesita articular esfuerzos con los Gobiernos locales para establecer programas de salud(AU)

Introduction: The new University Law 30220 allows improving the basic conditions of university quality in Peru, insofar it is pertinent to know students' conditions and origins in view of the continuous improvement of their academic progress. Objective: To determine the sociodemographic, economic and health-related characteristics of beneficiaries of basic complementary educational services of the National University of Frontera in Sullana, Peru. Methods: This is a descriptive study. The socioeconomic, family and health questionnaires of the beneficiaries were reviewed. The population was of census type and amounted to 1,285 students. Results: Of the total of students, 64 percent were women and 35 percent were men. Likewise, a high percentage of students with hourly water service was determined, as well as some were observed to work in sales occupations, self-employment and as motorcycle taxi drivers. Most of the students were observed to receive a monthly salary between 250-500 soles. Regarding vaccination, the students were observed to receive vaccines against tetanus, measles, hepatitis B and human papillomavirus vaccines. In addition, a low percentage of students with asthma, with some type of allergy or suffering from some disability, depression and sexual abuse was found. Conclusions: The complementary health service offered by the university is pertinent to reduce the risk of dropping out due to health-related reasons during undergraduate studies. Although it is necessary to coordinate efforts with local governments for establish health programs(AU)

Prevalence of sicca syndrome in the Peruvian population.

OBJECTIVES: Sjögren's syndrome is a complex and heterogeneous autoimmune disease characterised by ocular and oral dryness (1), which mainly affects the exocrine glands. The objective of this study was to determine the prevalence of sicca syndrome (SS) in the Peruvian population. The age and gender of patients with SS and their national prevalence and in each of the departments were defined. METHODS: This was a cross-sectional prevalence study. All the people for whom the Ministry of Health (MINSA) in Peru covered health treatments from January to December 2016 were taken into account. The patients with SS were either newly or previously diagnosed with sicca syndrome (Sjögren's) according to the international classification of diseases version 10 (ICD-10) of the World Health Organization (WHO). The prevalence was determined considering the number of cases of SS in the total population registered by the Ministry of Health (MINSA). RESULTS: 1,301 cases of SS were observed in a total population of 15,417,345 people served in 25 territories. The prevalence of SS in this population was 0.0084%, the prevalence rate was 8.4 cases per 100,000 persons (95% CI: 7.99-8.91). The prevalence of SS was higher in the territories of Tacna, Lima, La Libertad, Arequipa, Callao, and Apurímac. CONCLUSIONS: The results of this study show the prevalence of SS in the Peruvian population and serve to strengthen the health strategies of rheumatology, ophthalmology, and oral health to improve the diagnosis, treatment, follow-up of the disease, and the quality of life of patients with SS.
