Self-Reported Nutritional Status and Breakfast Characterization in Latin American University Students.

OBJECTIVE: To associate breakfast consumption frequency with self-reported nutritional status and dietary patterns of Latin American university students by human development. MATERIAL AND METHODS: This was a cross-sectional, multicenter observational study. University students from 11 Latin American countries (Argentina, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, Peru, Paraguay, Panama and Uruguay) were invited to participate by answering an online self-administered questionnaire on food consumption and sociodemographic indicators, associations were investigated using logistic regression. RESULTS: The logistic regression analysis showed significant associations between breakfast consumption and the crude model, models 2 and 3 in countries with very high and upper-middle/high human development. However, after adjustment in the most comprehensive model, the association is no longer statistically significant. In the fully adjusted model of the variables, a significant relationship was observed between breakfast consumption and both healthy and unhealthy dietary patterns. Specifically, students who typically consume breakfast exhibit greater consumption of oatmeal and fruits, as well as healthier dinner choices. Conversely, they exhibit lower consumption of fast food, sugary drinks, and juices. In particular, in highly developed countries, along with the mentioned foods, consumption of dairy was linked to breakfast consumption in a positive way, while alcohol consumption was negatively associated. CONCLUSION: University students who eat breakfast on a regular basis maintain a healthier diet in comparison to those who do not, irrespective of their country's level of human development.

Factors associated with the consumption of fruits and vegetables in latin american university students

Objective: Explore the association between compliance with recommended consumption (5-a-day) of fruits and vegetables (F&V) with sociodemographic factors of university students of Latin America. Subjects: We conducted an analytical cross-sectional study in which 4,880 university students from 10 Latin American countries completed a self-administered online survey. Methods: F&V consumption and other sociodemographic variables were measured according to a validated survey. Body mass index was self-reported. Ordinal logistic regression models were applied. Results: Regarding the consumption of F&V, 4.7% of men complied with the recommendation, while in women this value reached 7.7%. In the adjusted model, having a normal weight (OR= 0.59; 95% CI 0.44-0.7; p=<0.001), being female (OR= 0.67; 95% CI 0.49-0.89; p=<0.01), being enrolled in a health-related degree program (OR= 0,60; IC95% 0,45-0,78; p<0.001), having professional parents (OR= 0.75; 95% CI 0.60-0.95; p=<0.05) and practicing physical activity (OR= 0.34; 95% CI 0.27-0.42; p=<0.001) were associated with compliance to F&V consumption recommendations. In the analysis by country, physical activity was the variable most associated with F&V consumption. Conclusion: We observed a low consumption of F&V in university students. The variables associated with compliance to the F&V recommendation were being normal weight, female, being enrolled in a health-related degree program, having professional parents, and practicing physical activity, the latter being the most important variable.

Objetivo: Explorar la asociación de la frecuencia de cumplimiento de las recomendaciones de consumo (5 al día) de frutas y verduras (F&V) con factores sociodemográficos de estudiantes universitarios de América Latina. Metodología: Se realizó un estudio transversal analítico con 4.880 estudiantes universitarios de 10 países de América Latina, quienes completaron una encuesta en línea autoadministrada. Se midió el consumo de F&V y otras variables sociodemográficas según una encuesta previamente validada. El índice de masa corporal fue autoinformado.

En el análisis por país, la actividad física fue la variable más asociada al consumo de F&V. Conclusión: Se observa un bajo consumo de F&V en estudiantes universitarios, y entre las variables asociadas al cumplimiento de la recomendación de F&V se encuentran estar normopeso, sexo femenino, estar cursando una carrera relacionada con la salud, tener los padres y la práctica de actividad física, siendo esta última la variable más importante.

Quality of life in Down syndrome in Brazil: a cross-sectional study.

BACKGROUND: Down syndrome is the most commonly genetic cause of developmental delay and intellectual disability, affecting 1:700 live births. It is associated with heart disease and recurrent infections, among other complications that greatly impair the patient's quality of life. OBJECTIVE: To evaluate the major factors associated with quality of life in a cohort of patients with Down syndrome. METHODS: We assessed 1,187 patients with Down syndrome, older than 4 years old, with an adaptation of the Personal Outcomes Scale validated for Portuguese language, interviewing patients, parents, and caregivers. RESULTS: A bad quality of life was reported in 56.4% of the sample. The main factors associated with better quality of life were female sex, first medical visit before 4 months old, higher parental education, a professionally active mother, and prenatal care. The main factors associated with worse quality of life were family history of alcohol abuse and psychiatric disorders and comorbidity with autism and epilepsy. CONCLUSION: Clinical comorbidities such as autism and epilepsy carry a heavy burden among patients with Down syndrome, while factors related to family support, such as employment status and educational background of the parents, enhance quality of life. The factors associated with quality of life among patients with Down syndrome should be adequately evaluated in medical consultation and targeted in public health policies.

ANTECEDENTES: A síndrome de Down é a mais comum causa identificável de atraso de desenvolvimento e deficiência intelectual, afetando 1 a cada 700 nascidos vivos.

Asociación entre consumo de alcohol y exceso de peso entre estudiantes universitarios de América Latina

Introducción: El sobrepeso y la obesidad son problemas de salud pública de nivel mundial. Si bien existe información respecto al consumo de alcohol en estudiantes universitarios durante la pandemia, pocos autores han señalado la asociación entre este hábito y el exceso de peso en esta población. El objetivo fue determinar la asociación entre el consumo de alcohol y el exceso de peso en estudiantes universitarios de 10 países de Latinoamérica durante la pandemia por COVID-19. Metodología: Se realizó un estudio transversal y multicéntrico con 4.539 estudiantes universitarios matriculados en diez países de América Latina. Para la valoración del consumo de alcohol se utilizó la pregunta ¿Consumes bebidas alcohólicas? (1 porción 1 vaso de 200 ml). El índice de masa corporal (IMC) se determinó a partir del peso y la altura auto informado. Para determinar si el exceso de peso (IMC ≥25 kg/m2) estaba asociado con el consumo de alcohol, se utilizó un análisis de regresión logística, ajustado por edad, sexo, año de estudio, nivel socioeconómico, actividad física y tabaquismo. Resultados: Entre los estudiantes con estado nutricional normal, un 59,6% no consumía alcohol, mientras entre los que presentaban un exceso de peso era un 55,1%. Los estudiantes que consumían 2 o más porciones de alcohol al día tenían 2,18 veces más riesgo de tener exceso de peso (OR: 2.18 [95% IC: 1,26 a 3,77]), comparado con aquellos que no consumían alcohol. Conclusión: Se observó que aquellos estudiantes que consumieron más alcohol tuvieron más probabilidades de tener exceso de peso.

Introduction: Overweight and obesity are public health problems worldwide. Alcoholic beverages could increase total energy intake causing an increase in body weight. However, few authors have pointed out the association between this habit and excess weight in this population. The objective of this study was to determine the association between alcohol consumption and excess weight in university students from 10 Latin American countries during the COVID-19 pandemic. Methodology: A cross-sectional and multicenter study was carried out with 4,539 university students enrolled in ten Latin American countries. To assess alcohol consumption, the question Do you consume alcoholic beverages? (1 portion 1 glass of 200 ml). Body mass index (BMI) kg/m2 was determined from self-reported weight and height. To determine if excess weight was associated with alcohol consumption, a logistic regression analysis was used, adjusted for age, sex, year of study, socioeconomic level, physical activity, and smoking. Results: Among students with normal nutritional status, 59.6% did not consume alcohol, while among those with a BMI ≥25 kg/m2 it was 55.1%. Students who consumed 2 or more servings of alcohol per day had a 2.18 times greater risk of being overweight (OR: 2.18 [95% CI: 1.26 to 3.77]), compared with those who did not consume alcohol. Conclusion: It was observed that those students who consumed more alcohol were more likely to be overweight.

Microbiota unbalance in relation to high-risk human papillomavirus cervical infection.

OBJECTIVES: To assess vaginal dysfunction using basic vaginal states and the presence of lactobacillary microbiota in patients with human papillomavirus (HPV) infection with no squamous intra-epithelial lesions (SIL), with low-grade squamous intra-epithelial lesions (L-SIL), and with high-grade squamous intra-epithelial lesions (H-SIL) or squamous cell carcinoma compared with a control group (HPV-negative); to establish the prevalence of bacterial vaginosis, candidiasis, and trichomoniasis in the different age groups; and to characterize the species of lactobacilli according to the type of lesion. METHODS: A cross-sectional study was carried out of patients who underwent clinical examination and collection of vaginal fornixes to study basic vaginal states and culture. Species identification of lactobacilli was performed by mass spectrometry. The results were analyzed using the χ2 and Fisher's tests; p<0.05 was considered significant. High-risk viral types were determined using a multiplex real-time polymerase chain reaction test. RESULTS: A total of 741 patients were analyzed and divided into three age groups: Group 1 aged 18-24 years (n=138), Group 2 aged 25-50 years (n=456), and Group 3 aged >50 years (n=147). All groups were further divided into an HPV-negative (control) group and an HPV-positive group without lesions, with L-SIL, or with H-SIL/squamous cell carcinoma. The prevalence of unbalanced basic vaginal states in patients with H-SIL/squamous cell carcinoma was 72.7% (p=0.03) in Group 1, 53.1% (p=0.05) in Group 2, and no cases of unbalance were detected in Group 3. The prevalence of bacterial vaginosis in women with H-SIL/squamous cell carcinoma in Group 1 was 54.5% and in Group 2 was 43.7%. Patients with H-SIL/squamous cell carcinoma had a prevalence of 21.4% of Lactobacillus crispatus, 42.9% of L. jensenii, and 14.3% of L. iners. CONCLUSIONS: A greater unbalance of vaginal microbiota was observed in patients with SIL, especially in those with H-SIL/squamous cell carcinoma. In this group, an increase in L. jensenii and L. iners compared with control was found. L. crispatus had a similar prevalence to the control group. It is important to characterize the lactobacilli species since the unbalance alters the vaginal microenvironment and acts as a co-factor in the persistence of HPV infection.

[Complete androgen insensitivity syndrome: diagnosis and multidisciplinary management]. / Síndrome de insensibilidad completa a los andrógenos: diagnóstico y manejo multidisciplinario.

Background: Complete androgen insensitivity syndrome (CAIS) is a sexual differentiation disorder, caused by a defect in the androgen receptor gene (AR; OMIM# 313700). It is characterized by the resistance of target tissues to the action of testosterone, which prevents normal male genital development. The objective is to describe a family case of CAIS and highlight the importance of multidisciplinary medical management and early diagnosis of this syndrome. Clinical case: We present two cases of SICA in a Mexican family. Case 1: 18-year-old female patient with primary amenorrhea and a history of surgery at an early age, without performing gonadectomy. Case 2: 11-year-old female patient who, due to the history of her sister, underwent surgery at that age. In both patients, absence of uterus and ovaries, hypoplastic vagina and male gonads is reported. The 46,XY karyotype was detected with the GTG and CBG band technique and fluorescent in situ hybridization with the presence of the Y chromosome in 100% of the cells analyzed. Although both patients were identified with their assigned sex, they were referred to the institution's psychiatric clinic. Conclusions: The importance of multidisciplinary management for the diagnosis of SICA at an early age is discussed, in order to make decisions regarding the treatment and management of patients, avoiding malignant transformation of the male gonads.

Introducción: el síndrome de insensibilidad completa a los andrógenos (SICA) es un desorden de la diferenciación sexual, causado por un defecto en el gen receptor de andrógenos (AR; OMIM# 313700). Se caracteriza por la resistencia de los tejidos diana a la acción de la testosterona, lo que impide el desarrollo genital masculino de manera normal. El objetivo es describir un caso familiar de SICA y destacar la importancia del manejo médico multidisciplinario y el diagnóstico temprano de este síndrome. Caso clínico: presentamos dos casos de SICA en una familia mexicana. Caso 1: paciente de 18 años con amenorrea primaria y antecedente de intervención quirúrgica a edad temprana, sin realizarle gonadectomía. Caso 2: paciente de 11 años que debido al antecedente de su hermana fue intervenida quirúrgicamente a esa edad. En ambas pacientes, se reporta ausencia de útero y ovarios, vagina hipoplásica y gónadas masculinas. El cariotipo 46,XY fue detectado con técnica de bandas GTG y CBG e hibridación in situ fluorescente con presencia del cromosoma Y en el 100% de las células analizadas. Aunque ambas se identificaban con su sexo de asignación, fueron referidas a consulta de psiquiatría de la institución. Conclusiones: se discute la importancia del manejo multidisciplinario para el diagnóstico de SICA a edades tempranas con la finalidad de tomar decisiones respecto al tratamiento y manejo de las pacientes y evitar la malignización de las gónadas masculinas.

Índice de massa corporal, nutrição e atividade física em crianças e adolescentes com síndrome de Down / Body-mass index, nutrition and physical activity in children and adolescents with Down syndrome

Objetivo: Descrever e comparar hábito nutricional, prática de atividade física e índice de massa corporal (IMC) de crianças e adolescentes com síndrome de Down acompanhados em ambulatório especializado de um hospital terciário no sul do Brasil. Método: Estudo transversal realizado a partir da análise de prontuário de pacientes com síndrome de Down em idade escolar e adolescentes acompanhados em ambulatório especializado do Complexo Hospital de Clínicas da Universidade Federal do Paraná. A alimentação foi considerada adequada se consistisse em alimentos de todos os grupos nas três refeições principais e um ou dois lanches e água nos intervalos. Sedentarismo foi definido como tempo de atividade física inferior a 300 minutos por semana. O estado nutricional foi avaliado usando as curvas de IMC da Organização Mundial da Saúde, 2007.Resultados: O estudo incluiu 755 pacientes, sendo 236 (31,3%) crianças e 519 (68,7%) adolescentes. Sobrepeso e obesidade foram observados em 10,7% e 14,8% da população, respectivamente, sem diferença significativa entre os gêneros. Alimentação inadequada foi observada em 34,6% e sedentarismo em 23,7% dos pacientes. IMC elevado foi observado em 20,3% das crianças e 27,9% dos adolescentes (p=0,026). Observou-se sedentarismo em 29,5% dos adolescentes e 11% das crianças (p<0,001). Alimentação inadequada também foi mais prevalente em adolescentes, porém sem diferença estatística. Pacientes com IMC elevado, em comparação com eutróficos, tiveram maior prevalência de alimentação inadequada e sedentarismo, com significância estatística. Nesse subgrupo, o sedentarismo foi observado em 25% das crianças e 57,2% dos adolescentes (p<0,001). Conclusão: Adolescentes com síndrome de Down apresentam maiores taxas de IMC elevado e sedentarismo comparados com crianças. Estudos específicos em educação em saúde para essa população são necessários com o objetivo de promover hábitos de vida saudáveis e prevenir a obesidade com efetividade. [au]

Objective: To describe and compare the nutritional habits, physical activity, and body mass index (BMI) of children and adolescents with Down syndrome followed up in the specialized outpatient clinic of a tertiary hospital in southern Brazil. Method: Cross-sectional study conducted from the analysis of medical records of patients with Down syndrome at school age and adolescents followed up at the Complexo Hospital de Clínicas of the Universidade Federal do Paraná. The diet was considered adequate if it consisted of foods from all groups in the three main meals and one or two snacks and water in the intervals. A sedentary lifestyle was defined as physical activity time of fewer than 300 minutes per week. Nutritional status was assessed using BMI curves from the World Health Organization, 2007. Results: The study included 755 patients, of whom 236 (31.3%) were children and 519 (68.7%) were adolescents. Overweight and obesity were observed in 10.7% and 14.8% of the population, respectively, without significant gender differences. Inadequate diet was observed in 34.6% and sedentarism in 23.7% of the patients. High BMI was observed in 20.3% of children and 27.9% of adolescents (p=0.026). Sedentarism was observed in 29.5% of adolescents and 11% of children (p<0.001). Inadequate diet was also more prevalent in adolescents but without statistical difference. Patients with high BMI, compared to eutrophic patients, had a higher prevalence of inadequate diet and sedentarism, with statistical significance. In this subgroup, sedentarism was observed in 25% of children and 57.2% of adolescents (p<0.001). Conclusion: Adolescents with Down syndrome have higher rates of high BMI and sedentarism compared to children. Specific studies in health education for this population are necessary to promote healthy lifestyle habits and effectively prevent obesity. [au]

Vaginal States: Detection of Conversion Processes in Women Using Contraception and Characterization of Vaginal Lactobacillus Species.

BACKGROUND: The vaginal microenvironment, regulated by an immune system, can be protected or altered by many factors, including contraceptive methods. OBJECTIVE: The objective of this study is to evaluate the impact of contraceptive methods on the basic vaginal states (BVSs) and to identify culturable vaginal Lactobacillus species. METHODS: This is a prospective, consecutive, longitudinal, and descriptive study. The vaginal contents of 208 women were sampled prior to initiating contraception and six months later. The BVSs were established using the balance of vaginal content (BAVACO) methodology that evaluates microbiota and vaginal inflammatory reaction (VIR). Lactobacillus species were characterized by biochemical tests and mass spectrometry. The following contraceptive methods were evaluated: combined oral contraceptive pill (COCP), condom (CON) and rhythm method (RHYT). McNemar's test was used. RESULTS: Of the 208 women, 171 attended both examinations. In the COCP group (n=127), 83 vaginal contents maintained a normal microbiota, 1 sample became dysbiotic, and 37/43 dysbiotic microbiota samples reverted to normal (p<0.0001). A conversion to BVS with VIR was detected in the CON group (n=31) (p=0.001). The RHYT group (n=13) maintained its initial BVSs. The predominant Lactobacillus species found were L. crispatus and L. gasseri, with a trend toward a positive association between L. crispatus and COCP (OR=2.82; p=0.058). CONCLUSION: Hormone administration corrected the dysbiosis and preserved a normal BVS. The CON increased the VIR. The protection of the microbiota observed in the rhythm method probably responds to a systemic hormonal influence. The trend toward a positive association between COCP and L. crispatus, with its protective properties, evidenced an effective hormonal relationship.

Biochemical profiling study in umbilical cord blood in mothers with metabolic disorders.

BACKGROUND: During pregnancy metabolic disorders that affect differently the fetus, are known. These could be early or late disorders. OBJECTIVES: To analyze different biochemical parameters in umbilical cord blood (UCB) of healthy and pathological newborns from mothers with metabolic disorders. MATERIALS AND METHODS: Samples from UCB (121) were analyzed of newborn from mothers with metabolic disorders who attended at Obstetrics Division. Patients were consecutive, prospective and transversally studied. Newborn were classified as healthy (n = 65) and pathological (n = 56). The maternal metabolic disorders were gestational or non-gestational diabetes, glucose intolerance, insulin resistance and/or obesity).The disorders of the pathological newborns were intrauterine growth restriction (IUGR) and/or fetal distress. Glucose (Glu), urea, creatinine, uric acid (UA), total bilirubin (TB), total proteins (TP), albumin (Alb), transaminases (ALT/AST), alkaline-phosphatase (ALP), gammaglutamyltranspeptidase (GGT), creatinkinasa (CK), lactatedehydrogenase, amylase (amy), pseudocholinesterase, iron, calcium, phosphorus, magnesium (Mg), sodium, potassium, chlorine, cholesterol (Chol), HDL-Chol, LDL-Chol, triglycerides (TG), high sensitivity C reactive protein (hsCRP) were determined by recommended methods. T-Student's and Mann Withney tests were applied, p < .05. RESULTS: Pathological neonates (n: 56) showed a significant decrease in maternal gestation weeks (GW) and in newborn weight (NW) with respect to healthy newborns (n: 65) from mothers with metabolic disorders (p < .0001). Pathological neonates from mothers with metabolic pathologies (n: 56) showed significant increases in Chol, TG, TB (p < .01), LDL-Chol, UA, Mg, hsCRP, ALP levels (p < .05) and significant decreases in TP, Alb (p < .0001) and Glu, ALT, CK, GGT, amy (p < .05) in UCB with respect to healthy newborns. CONCLUSIONS: In pathological newborn, the decrease in GW and NW would be related to IUGR that accompany these metabolic disorders. The increases observed of the analyzed parameters would be related to cellular destruction associated to maternal pathology and decreases of the parameters to IUGR with hepatic immaturity.

Respiratory and otolaryngological disorders in Down syndrome from one center in Brazil.

Down syndrome (DS) is the most common chromosomal condition. Anatomical and functional variations in the upper and lower airways are component manifestations of the syndrome and increase the risk of various medical problems. The objective of this study was to determine the prevalence of otorhinolaryngological and respiratory diseases in a DS outpatient clinic over a 3-year period. Medical records data from 1207 patients were retrospectively reviewed. Newborn Hearing Screening was positive in 7.1% of patients. Brainstem auditory evoked potential was performed in 1101 children and showed a hearing loss of 19.8% in the first year. It was positive in 21% of 1021 exams. Audiometry was altered in 64 of 994 exams (6.4%), showing a conductive loss in 90%. Adenotonsillectomy was performed in 308 (25.5%) patients, and 169 (14.0%) required serous otitis ventilation tubes. Asthma was observed in 140 (11.6%) patients, and allergic rhinitis in 544 (56.6%). There were hospitalizations for invasive infection in 480 (39.8%) children, and two (0.2%) patients had severe septicemia from pulmonary focus. Five (0.4%) infants had laryngotracheomalacia, and one patient had anomalous right tracheal bronchus. Recognizing the prevalence of respiratory and otorhinolaryngological disorders in patients with DS allows the promotion of optimal follow-up and early treatment, preventing the development of sequelae.

Sor Ema Téllez Muro: un himno a la vida y a la preservación del cuidado humanizado / Sister Ema Téllez Muro: a hymn to life and to the preservation of humanized take care

En esta biografía Sor Ema Téllez Muro comparte algunas vivencias que ha tenido como mujer, enfermera y religiosa. Pertenece a la Congregación de las Hermanas de la Caridad del Verbo Encarnado. Trabajó muchos años en el Instituto Nacional de Cardiología Ignacio Chávez, en la ciudad de México, de donde recientemente se jubiló. El contenido de esta historia de vida se construyó a partir de tres entrevistas realizadas entre 2018-2019, cuyas preguntas detonantes favorecieron la apertura de diversos temas que avizoran su camino en la enfermería. Su recorrido por la vida no ha sido sencillo, ha tenido experiencias muy duras que le sirvieron para confirmar su espiritualidad y sobre todo encontrar la reconciliación y el perdón. Refiere que el humanismo es un elemento clave para otorgar cuidado integral a sus semejantes y asevera que el trabajo en equipo es una gran estrategia para motivar a las nuevas generaciones en el fomento de valores. En su filosofía mantiene que con las enseñanzas que se dan y proyectan hacia la gente se pueden generar grandes transformaciones personales y personales. Anhela que la compasión y la generosidad, en su sentido amplio, prevalezcan como base fundamental en la atención que brinda el personal de Enfermería.

Ophthalmological abnormalities in Down syndrome among Brazilian patients.

Down syndrome is the most common chromosomal disorder, affecting 1/700 live births. Among the clinical findings, one constant concern is the high prevalence of visual disorders that, if left untreated, can negatively affect child development. The aim of this study was to determine the prevalence of ophthalmological findings among patients who attended an outpatient clinic for patients with Down syndrome in southern Brazil between 2005 and 2016. A cross-sectional study including 1,207 patients medical records were done, which 492 (40.8%) had some ophthalmological disorder. These data were subjected to descriptive analysis using Statistica software. Among the 492 patients with any ophthalmological disease, the need for glasses was found in 434 (36%) patients, keratoconus in 254 (42.1%), congenital cataract in 27 (15.1%), nasolacrimal duct obstruction in 25 (2.0%), strabismus in 22 (1.9%), nystagmus in four (0.3%), and juvenile cataract in two (0.2%). Two young adults with keratoconus underwent corneal transplantation. Although the prevalence of an ophthalmological disease among the present sample (40.8%) was lower than described in the current literature, it still reinforced the importance of routine and early evaluations in infants. These should begin at 6 months of age and be repeated half-year until 2 years old, annually until 7 years old, biennial in adolescents, and triennial in adults and elderly. Our findings of a high frequency of keratoconus support a detailed corneal study in such patients for early detection and treatment.

Asociación entre nivel de conocimiento y prácticas de cuidadores de niños de 2 a 5 años sobre la alimentación infantil / Association between knowledge level and practices on child food of 2 to 5 years children caregivers

El objetivo de este trabajo de investigación fue determinar la asociación entre el nivel de conocimiento y las prácticas de cuidadores sobre alimentación infantil de niños de 2 a 5 años que acudían al Hospital Materno Infantil de Loma Pytá de la ciudad de Asunción en junio de 2019. Estudio observacional, analítico de corte transverso. La población a estudiar estuvo compuesta por cuidadores de niños de 2 a 5 años que consultaban en el Hospital Materno Infantil de Loma Pytá del Ministerio de Salud. Se aplicó un cuestionario en el cual se incluyeron preguntas en relación nivel de conocimientos y prácticas a los cuidadores sobre alimentación de sus niños, además de una frecuencia alimentaria. En cuanto al nivel de conocimiento sobre los hábitos alimentarios que tenían los cuidadores de los niños, la mayoría tenía un conocimiento medio (40%). En relación a las prácticas sobre los hábitos alimentarios que los cuidadores tenían respecto a los niños, 80% de ellos tenían un nivel inadecuado. En cuanto a la asociación entre el nivel de conocimientos y el nivel de práctica se encontró relación estadísticamente significativa entre estas variables con un valor de p<0,001 para la prueba de Chi Cuadrado. Esto significa que existía relación entre lo que sabían los cuidadores de estos niños y las prácticas que realizaban

The objective of this research work was to determine the association between the level of knowledge and practices of caregivers on infant feeding of children from 2 to 5 years old who attended the Hospital Materno Infantil de Loma Pyta from the city of Asunción in June 2019. This was an observational, analytical cross-sectional study. The population to be studied was composed of caregivers of children aged 2 to 5 who consulted at the Hospital Materno Infantil de Loma Pyta. A questionnaire with questions related to the level of knowledge and practice was applied to caregivers about feeding their children, as well as the eating frequency. Regarding the level of knowledge about the eating habits of the children, the majority had an average knowledge (40%). In relation to the practices about the eating habits the caregivers had with the children, 80% of them had an inadequate level. In respect to the association between the level of knowledge and the level of practice, a statistically significant relationship was found between these variables with a value of p <0.001 for the Chi-square test. This means that there was a relationship between the knowledge of the caregivers and the practices they performed

Fetal coenzyme Q10 deficiency in intrahepatic cholestasis of pregnancy.

AIM: Intrahepatic cholestasis of pregnancy (ICP) is considered a high-risk condition because it may have serious consequences for the fetus health. ICP is characterized by the accumulation of bile acids in maternal serum which contribute to an imbalance between the production of reactive oxygen species and the antioxidant defenses increasing the oxidative stress experienced by the fetus. Previously, it was reported a significant decrease in plasma coenzyme Q10 (CoQ10) in women with ICP. CoQ10 is a redox substance integrated in the mitochondrial respiratory chain and is recognized as a potent antioxidant playing an intrinsic role against oxidative damage. The objective of the present study was to investigate the levels of CoQ10 in umbilical cord blood during normal pregnancy and in those complicated with ICP, all of them compared to the maternal ones. METHODS: CoQ10 levels and bile acid levels in maternal and umbilical cord blood levels during normal pregnancies (n=23) and in those complicated with ICP (n=13), were investigated. RESULTS: A significant decrease in neonate CoQ10 levels corrected by cholesterol (0.105±0.010 vs. 0.069±0.011, P<0.05, normal pregnancy vs. ICP, respectively), together with an increase of total serum bile acids (2.10±0.02 vs. 7.60±2.30, P<0.05, normal pregnancy vs. ICP, respectively) was observed. CONCLUSIONS: A fetus from an ICP mother is exposed to a greater risk derived from oxidative damage. The recognition of CoQ10 deficiency is important since it could be the starting point for a new and safe intervention strategy which can establish CoQ10 as a promising candidate to prevent the risk of oxidative stress.

Flavonoids as positive allosteric modulators of α7 nicotinic receptors.

The use of positive allosteric modulators (PAM) of α7 nicotinic receptors is a promising therapy for neurodegenerative, inflammatory and cognitive disorders. Flavonoids are polyphenolic compounds showing neuroprotective, anti-inflammatory and pro-cognitive actions. Besides their well-known antioxidant activity, flavonoids trigger intracellular pathways and interact with receptors, including α7. To reveal how the beneficial actions of flavonoids are linked to α7 function, we evaluated the effects of three representative flavonoids -genistein, quercetin and the neoflavonoid 5,7-dihydroxy-4-phenylcoumarin- on whole-cell and single-channel currents. All flavonoids increase the maximal currents elicited by acetylcholine with minimal effects on desensitization and do not reactivate desensitized receptors, a behaviour consistent with type I PAMs. At the single-channel level, they increase the duration of the open state and produce activation in long-duration episodes with a rank order of efficacy of genistein > quercetin ≥ neoflavonoid. By using mutant and chimeric α7 receptors, we demonstrated that flavonoids share transmembrane structural determinants with other PAMs. The α7-PAM activity of flavonoids results in decreased cell levels of reactive oxygen species. Thus, allosteric potentiation of α7 may be an additional mechanism underlying neuroprotective actions of flavonoids, which may be used as scaffolds for designing new therapeutic agents.
