RESUMO

Introduction: There are a set of conditions that directly affect the quality of life of older adults, causing marginalization and discrimination of this age group. Objective: Determining the factors that affect the perception of discrimination and quality of life of older adults in the province of El Oro, Ecuador. Methods: Observational, descriptive, qualitative-phenomenological, cross-sectional, cross-sectional study in older adults aged 65 years, between September 2019 and November 2020. The sample consisted of 399 older adults. The questionnaire "Biopsychosocial assessment of older adults from a bioethical approach" was used. The following variables were measured: discrimination and self-perception of quality of life. Multiple correspondence analysis was used to examine the association between discrimination, quality of life and the variables under study. Results: 61.7% of the respondents considered that discrimination exists, with ageism predominating. The variable most related to the perception of discrimination of the MAs was the treatment in health care, and the family environment. The quality of life in a significant percentage was unsatisfactory due to: their family environment, poor social integration and dissatisfaction with their health. Conclusions: The quality of life of older adults was unsatisfactory in almost half of the respondents, influenced by the relationship with the family, social integration, and health status. The older adults reported that there is discrimination and ageism in the treatment perceived in the health services and the family environment, in violation of the principles of bioethics.

Introducción: En la vejez se presentan un conjunto de condiciones que afectan directamente la calidad de vida del adulto mayor, ocasionando marginación y discriminación de este grupo etario. Objetivo: Determinar los factores que inciden en la percepción de discriminación y calidad de vida de los adultos mayores de la provincia El Oro, Ecuador. Métodos: Estudio observacional, descriptivo, cualitativo-fenomenológico, de corte transversal, en adultos mayores de 65 años, entre septiembre del 2019 y noviembre del 2020. La muestra fue 399 adultos mayores. Se utilizó el cuestionario: "Valoración biopsicosocial del adulto mayor desde un enfoque bioético". Se midieron las variables: discriminación y autopercepción de calidad de vida. Se utilizó el análisis de correspondencia múltiple, para examinar la asociación entre discriminación, calidad de vida, y las variables en estudio. Resultados: El 61,7% de los encuestados consideró que existe discriminación, predominando el edadismo. La variable más relacionada a la percepción de discriminación de los AM fue el trato en la atención sanitaria, y el entorno familiar. La calidad de vida en un porcentaje significativo fue insatisfactoria debido a: su entorno familiar, la poca integración social y la insatisfacción con su salud. Conclusiones: La calidad de vida de los adultos mayores fue poco satisfactoria en casi la mitad de los encuestados, influenciada por la relación con la familia, la integración social, y el estado de salud. Los adultos mayores refirieron que existe discriminación, y edadismo en el trato percibido en los servicios de salud, y el entorno familiar, incumpliéndose con los principios de la bioética.

RESUMO

Fatigue has been characterized as a post COVID-19 condition known to persist months after SARS-CoV-2 infection. COVID-19 has been reported to be associated with impaired cognitive function, including disorders in attention, memory, information processing, and executive functions. The objective of this study was to determine if post-COVID fatigue, manifested as tiredness while performing low-intensity physical activity, has a detrimental effect on neuropsychological performance, to achieve this, we randomly selected 20 participants with post-COVID fatigue and 20 SARS-CoV-2 negative age-matched controls from a database of 360 residents of Tijuana, Baja California in a cross-sectional study design. All 40 participants responded to a health survey, along with a neuropsychological assessment test via telephone call. Statistical analysis was performed using a multiple linear regression model including the following independent variables: study condition (post-COVID fatigue or negative control), sex, age, years of education, hypertension, asthma, administration of supplemental oxygen during COVID-19 recovery, and the hour at which the evaluation started. Significant regression analysis was obtained for all global parameters of the assessment, including BANFE-2 score (p = 0.021, R2 Adj. = 0.263), NEUROPSI score (p = 0.008, R2 Adj. = 0.319), and total errors (p = 0.021, R2 Adj. = 0.263), with significant regression coefficients for study condition on two global parameters, BANFE-2 score (p = 0.028, ß = - 0.371) and NEUROPSI score (p = 0.010, ß = -0.428). These findings suggest that the presence of post-COVID fatigue is a factor associated with a decrease in neuropsychological performance.

RESUMO

Beneficial Bacillus strains can be administered to livestock as probiotics to improve animal health. Cyclic lipopeptides produced by Bacillus such as surfactins may be responsible for some of the beneficial effects due to their anti-inflammatory and immunomodulatory activity. The aim of the present study was to isolate and evaluate the biocompatibility of native Bacillus spp. strains and their surfactin-like lipopeptides in vitro and in vivo to determine their potential to be used on animals. Biocompatibility of endospore suspensions (108 UFC/mL), and different dilutions (1:10; 1:50; 1:100; 1:500, and 1:1000) of Bacillus lipopeptide extracts containing surfactin was tested on Caco-2 cells by microculture tetrazolium-based colorimetric assay. Genotoxicity was tested on BALB/c mice (n = 6) administered 0.2 mL of endospore suspensions by the bone marrow erythrocyte micronuclei assay. All the isolates tested produced between 26.96 and 239.97 µg mL- 1 of surfactin. The lipopeptide extract (LPE) from isolate MFF1.11 demonstrated significant cytotoxicity in vitro. In contrast, LPE from MFF 2.2; MFF 2.7, TL1.11, TL 2.5, and TC12 had no cytotoxic effect (V% > 70%) on Caco-2 cells, not affecting cell viability signifficantly in most treatments. Similarly, none of the endospore suspensions affected cell viability (V% > 80%). Likewise, endospores did not cause genotoxicity on BALB/c mice. This study was elementary as a first step for a new line of research, since it allowed us to choose the safest isolates to keep working on the search of new potentially probiotic strains destined to production animals to improve their performance and health.

RESUMO

OBJECTIVE: the aim of the present article was to test a self-care model explained by the relationship between self-efficacy, body image, obsessive-compulsive disorder, and depression in people with bariatric surgery in the city of Tijuana, Baja California, Mexico. METHOD: this was a correlational cross-sectional study carried out between August and December 2020. Validated instruments were administered to 102 participants to measure their self-care capacity, general self-efficacy, psychopathological symptoms, and body image perception and satisfaction. The variables of interest were analyzed using descriptive statistics and the Pearson and Spearman correlation coefficients were used to develop a model using path analysis. RESULT: a significant model was obtained with adequate goodness-of-fit indicators (chi-square χ2 (8) = 11.451, p = .177; root mean square error of approximation (RMSEA)= 0.000; goodness-of-fit index (GFI)= 0.965; comparative fit index (CFI)= 0.985; parsimonious normed fit index (PNFI)= 0.509, and Akaike information criterion (AIC)= 37.451). Self-efficacy (Zß=0.294) and body image dissatisfaction (So= -0.376) were shown to influence self-care abilities while psychopathological symptoms influenced body dissatisfaction: obsessive-compulsive disorder (Zß=0.370) and depression (Zß=0.320). CONCLUSION: adequate levels of self-efficacy and body satisfaction predict a high capacity for self-care.

Introduction: Chronic kidney disease is considered a disease with serious repercussions for the society and health policies, with high incidence and prevalence due to the rise of diseases such as arterial hypertension and diabetes mellitus. Objective: To detect, in a timely manner, adults at high risk of developing chronic kidney disease in order to preserve their health, and thus slow the onset and progression of kidney damage. Methods: A descriptive, cross-sectional and quantitative study was carried out with 404 adult relatives of nursing students from the Technical University of Machala, El Oro, Ecuador. The questionnaire for early detection of renal disease risk of the Da Vita group was used. Results: Arterial hypertension was found as the main disease (27.2 percent), followed by type II diabetes mellitus (9.4 percent). The chi-square test showed no difference in the history of hypertension between both sexes (p > 0.05). Of the study population, 55.6 percent were obese/overweight, 54.7 percent reported a sedentary lifestyle, and 120 persons (29.7 percent) had a family history of chronic kidney disease. A total of 137 persons (33.9 percent) reported consuming nonsteroidal antiinflammatory drugs. The total of patients with arterial hypertension and diabetes mellitus (n = 17; 4.21 percent) were obese, sedentary, and had a family history of chronic kidney disease, a reason why they were considered at high risk. They were referred to consultation for study, in addition to receiving educational talks. Conclusions: The health professional can and should have an impact on the early detection of chronic kidney disease through screening and educational programs that increase the knowledge of the susceptible population(AU)

RESUMO

The objective of this study was to evaluate the validity and reliability of OTESSED, an online test for the self-detection and prevention of risk factors for eating disorders and related problems, such as depression, social anxiety, and self-injury, in samples of male and female adolescents. Participants formed a non-probability sample of N = 577 high school students. The mean ages of boys and girls were the same (Mage = 15.61; SD = 0.73). Among the main results, scales of depression, self-injury, social anxiety, and risky eating behavior (REB) with construct validity (CFA) were obtained. The first two showed the same structure (two factors per sex), with an appropriate reliability omega value (0.92), and a similar percentage of explained variance (≥50). The REB scale presented two factors for boys and three for girls, with an appropriate omega value (0.88) and explained variance percentage (0.56). The instrument validation process was completed, meeting the discriminant validity criterion for each scale of the OTESSED.

RESUMO

Introducción: El envejecimiento de la población en la actualidad es uno de los principales problemas a nivel mundial, debido al incremento en la esperanza de vida. Sin embargo, una mayor esperanza de vida no significa una mejor calidad de vida. Objetivo: Valorar el papel que desempeña la familia en la autopercepción de calidad de vida del adulto mayor. Métodos: Estudio descriptivo, observacional y transversal en adultos mayores aplicada en sujetos de ambos sexos en la provincia ecuatoriana de El Oro entre enero del 2018 y noviembre del 2019. La muestra quedó conformada por 399 pacientes. Los cuestionarios utilizados fueron: Valoración biopsicosocial del adulto mayor desde un enfoque bioético, y la Escala de Calidad de Vida WHOQOL-BREF. Resultados: El promedio de edad fue de 73,66 años ± 7,38 con un rango entre los 65 y 98 años. El 78,9 por ciento de los adultos mayores maltratados y el 75,9 por ciento de los adultos mayores con trato familiar regular refieren una calidad de vida deficiente. Solo el 18,3 por ciento de los adultos mayores bien tratados refirieron una calidad de vida deficiente, por lo que se observa una asociación entre el trato familiar y la percepción de la calidad de vida estadísticamente significativa. Se constató maltrato familiar por negligencia en los adultos mayores que refirieron una calidad de vida deficiente. Conclusiones: La familia posee un papel preponderante en la calidad de vida del adulto mayor(AU)

Introduction: Nowadays, population aging is one of the main problems worldwide, due to the increase in life expectancy. However, higher life expectancy does not mean better quality of life. Objective: To assess the role played by the family in the older adult's self-perception of quality of life. Methods: A descriptive, observational and cross-sectional study was carried out with older adults of both sexes in the Ecuadorian province of El Oro, between January 2018 and November 2019. The sample consisted of 399 patients. The questionnaires used were the Biopsychosocial Assessment of the Older Adult from a Bioethical Approach and the WHOQoL-BREF Quality of Life Scale. Results: The average age was 73.66 years ± 7.38 years, with a range between 65 and 98 years. A poor quality of life was reported by 78.9 percent of the mistreated older adults and 75.9 percent of the older adults with regular family treatment. Only 18.3 percent of the well-treated older adults reported a poor quality of life, which shows a statistically significant association between family treatment and perception of quality of life. Family mistreatment due to neglect was found in older adults who referred poor quality of life. Conclusions: The family has a preponderant role in the quality of life of the older adult(AU)

RESUMO

BACKGROUND AND OBJECTIVES: Micronutrient deficiencies are common among bariatric patients; this study aimed to determine whether a cognitive dissonance-based virtual program improved adherence to multivitamin use in bariatric patients from northern Mexico. METHODS AND STUDY DESIGN: A randomized controlled trial of the supplementation strategy was conducted over three months. The participants were randomized to an intervention or waitlisted control group and received two psycho-educative and four cognitive dissonance virtual sessions. Multiple linear regression was used to determine standardized estimates of associations between the intervention and dependent variables. Two path analyses were evaluated considering baseline and post-test measurements. RESULTS: Intervention was associated with higher concentrations of Hb (ß=0.758, p<0.001), vitamin D (ß=0.577, p<0.001), iron (ß=0.523, p<0.001), folate (ß=0.494, p<0.01), calcium (ß=0.452, p<0.01), higher adherence (ß=0.467, p<0.001), and level of knowledge (ß=0.298, p<0.05. CONCLUSIONS: The dissonance-based intervention potentiated the level of supplementation adherence. A higher level of adherence was reflected in micronutrient concentrations, thus providing confirmation of intervention. Thus, support is found for a multidisciplinary clinical practice that enhances nutrition status after bariatric surgery for obesity.
