[Body dissatisfaction, self-esteem, depressive symptoms, and nutritional status in adolescents]. / Insatisfacción corporal, autoestima, sintomatologia depresiva y estado nutricional en adolescentes.

In adolescence and especially in females, greater body dissatisfaction has been evidenced, which is defined as a negative evaluation of one's own body, being a strong predictor of eating disorders and obesity. OBJECTIVE: To relate body dissatisfaction with self-esteem, depression, and body mass index in adolescents. SUBJECTS AND METHOD: Quantitative, correlational, and cross-sectional study in a sample of 397 school adolescents (180 males and 217 females) from Concepción, Chile, aged 10 to 19 years, to whom the following instruments were applied: Body Shape Questionnaire (BSQ) to assess body dissatisfaction, Rosenberg Self-Esteem Scale, Beck's Depression Inventory-II for those older than 14 years, and Birleson Depression Self-Rating Scale for those younger than 14 years. Body mass index z-score was determined. Spearman's correlation coefficient was estimated for all variables. RESULTS: Body dissatisfaction was reported in 54.9 % of females and 18.3 % of males. Body dissatisfaction was positively correlated with age, z-BMI, and depression (p < 0.01) and negatively correlated with self-esteem (p < 0.01). When body dissatisfaction was differentiated by sex, the same significant correlations remained, except for age. CONCLUSIONS: The results confirm the relationship between body dissatisfaction with self-esteem, depression, and BMI. The importance of promoting healthy self-esteem and body image from an early age to prevent eating disorders and obesity is emphasized.

Perfil biosociodemográfico del cuidador principal informal del adulto mayor en una región de Ecuador / Biosociodemographic profile of the primary informal caregiver of the elderly in a region of Ecuador

La necesidad de servicios de cuidados prolongados a adultos mayores origina la actividad de ayuda no profesional y a la figura del cuidador principal informal. El objetivo de la investiga-ción fue describir el perfil del cuidador principal informal acompañante del paciente a consulta externa del Hospital de Atención Integral del Adulto Mayor en el último trimestre de 2021. Se hizo un estudio cuantitativo, observacional y descriptivo, en una población de 322 cuidadores principales informales de adultos mayores en el último trimestre de 2021, seleccionando una muestra de 190 individuos mediante un procedimiento del tipo sujetos voluntarios. El instrumento aplicado fue una guía de entrevista estructurada basada en la Encuesta de caracterización del cuidado de la díada cuidador familiar-persona con enfermedad crónica.

Además, el 86,3% realiza quehaceres domésticos. Se observó un deterioro de la condición de salud luego de iniciar en las funciones del cuidado y todos mencionaron padecer de alguna enfermedad; sin embargo, prevalecieron los que señalan recibir efectos emocionales positivos a partir del cuidado.

The need for long-term care services for the elderly originates the activity of non-professional help and the figure of the informal primary caregiver. This research aimed to describe the profile of the primary informal caregiver who accompanied the patient to the outpatient clinic of the Hospital de Atención Integral del Adulto Mayor in the last quarter of 2021. A quantitative, obser-vational, and descriptive study was carried out in a population of 322 primary informal caregi-vers of the elderly in the last quarter of 2021, selecting a sample of 190 individuals through a voluntary subject-type procedure. The applied instrument was a structured interview guide based on the Survey of Characterization of the Care of the Family Caregiver-person with a Chro-nic Illness Dyad. The care falls on the woman (83.2%), children (57.9%), married (48.9%), live with the elderly (42.6%), care for up to 4 family members; 17.9% who never receive help, care for between 1 and 6 years and dedicate up to 15 hours. In addition, 86.3% do housework. A dete-rioration of the health condition was observed after starting the care functions, and all of them mentioned suffering from some disease; however, those who reported receiving positive emotio-nal effects from care prevailed

Adaption and reliability of the Nutrition Environment Measures for stores (NEMS-S) instrument for use in urban areas of Chile.

OBJECTIVE: To adapt and assess reliability of the Chilean version of Nutritional Environment Measurement for Stores (NEMS-S-CHILE) to measure the food environment of stores in urban areas. DESIGN: NEMS-S-CHILE was the NEMS-S tool adapted to the Chilean food patterns; foods were grouped according to level of processing in (a) unprocessed or minimally processed foods, (b) processed culinary ingredients, (c) processed foods, and (d) ultra-processed foods, and scored according to NEMS-S-CHILE tool. Reliability inter evaluators was measured. SETTING: City of Concepción, Bio-Bio region, Chile. PARTICIPANTS: Seventeen of a total of 25 supermarkets, and 9 out of 10 street markets according to the municipal registry and the street market trade unions, representing 74.3% of both types of food premises in Concepción. RESULTS: Reliability inter evaluators was measured by the following aspects: product availability, price, quality, and variety, through the intraclass correlation coefficient (ICC), percent agreement, and Cohen's kappa analysis. Reliability was high for availability, where the kappa index and ICC were acceptable, ranging from moderate to high (0.42 to 1.00 for the kappa coefficient and 0.65 to 1.00 for ICC), as well as for prices (ICC: 0.65-1.00 ), variety (kappa: 0.76-1.00) and quality (percent agreement: 68.2- 100%). CONCLUSIONS: The adapted instrument, NEMS-S-CHILE, has a high reliability inter evaluators and can be useful to measure the availability of foods by the level of processing according to the prevalent food system in developing countries.

Temperatures Outside the Optimal Range for Helicobacter pylori Increase Its Harboring within Candida Yeast Cells.

Helicobacter pylori is capable of entering into yeast, but the factors driving this endosymbiosis remain unknown. This work aimed to determine if temperatures outside the optimal range for H. pylori increase its harboring within Candida. H. pylori strains were co-cultured with Candida strains in Brucella broth supplemented with 5% fetal bovine serum and incubated at 4, 25, 37 or 40 °C. After co-culturing, yeasts containing bacteria-like bodies (Y-BLBs) were observed by optical microscopy, and the bacterium were identified as H. pylori by FISH. The H. pylori 16S rRNA gene was amplified from the total DNA of Y-BLBs. The viability of intra-yeast H. pylori cells was confirmed using a viability assay. All H. pylori strains were capable of entering into all Candida strains assayed. The higher percentages of Y-BLBs are obtained at 40 °C with any of the Candida strains. H pylori also increased its harboring within yeast in co-cultures incubated at 25 °C when compared to those incubated at 37 °C. In conclusion, although H. pylori grew significantly at 40 °C, this temperature increased its harboring within Candida. The endosymbiosis between both microorganisms is strain-dependent and permits bacterial cells to remain viable under the stressing environmental conditions assayed.

Identificación de variantes genéticas asociadas a hipercolesterolemia familiar en niños y adolescentes de la Región del Biobío, Chile / Identification of genetic variants associated with familial hypercholesterolemia in Chilean children and adolescents

Background: Familial hypercholesterolemia (FH) is commonly associated with mutations in-LDL receptor (LDLR), apolipoprotein B (APOB) and proprotein convertase subtilisin/kexin type 9 (PCSK9). Aim: To identify genetic variants associated with FH in a population of children and adolescents with hypercholesterolemia or a family history of-demonstrated early CVD. Material and Methods: Clinical and biochemical parameters were evaluated, and nine genes related to FH were sequenced namely LDLR, APOB, PCSK9, LDLRAP1, LIPA, APOE, ABCG5, ABCG8 and STAP1, in 55 children and adolescents aged 1 to 18 years old, from non-consanguineous families. Results: Mutations associated with FH were found in 17 children and adolescents, corresponding to p.Asp47Asn, duplication of exons 13-15 and p.Ser326Cys of the LDLR gene; p.Glu204* and Ile268Met of the APOE gene. Thirteen patients were heterozygous, two homozygous, two compound heterozygous, and one double heterozygous. Conclusions: Children and adolescents carrying mutations associated with FH were found by selective screening, which constitutes the first stage in the identification of genetic variants in our country.

Antibiotics as a Stressing Factor Triggering the Harboring of Helicobacter pylori J99 within Candida albicans ATCC10231.

First-line treatment for Helicobacter pylori includes amoxicillin and clarithromycin or metronidazole plus a proton pump inhibitor. Treatment failure is associated with antibiotic resistance and possibly also with internalization of H. pylori into eukaryotic cells, such as yeasts. Factors triggering the entry of H. pylori into yeast are poorly understood. Therefore, the aim of this study was to evaluate whether clarithromycin or amoxicillin trigger the entry of H. pylori into C. albicans cells. METHODS: H. pylori J99 and C. albicans ATCC 10231 were co-cultured in the presence of subinhibitory concentrations of amoxicillin and clarithromycin as stressors. Bacterial-bearing yeasts were observed by fresh examination. The viability of bacteria within yeasts was evaluated, confirming the entry of bacteria into Candida, amplifying, by PCR, the H. pylori16S rRNA gene in total yeast DNA. RESULTS: Amoxicillin significantly increased the entry of H. pylori into C. albicans compared to the control. CONCLUSION: the internalization of H. pylori into C. albicans in the presence of antibiotics is dependent on the type of antibiotic used, and it suggests that a therapy including amoxicillin may stimulate the entry of the bacterium into Candida, thus negatively affecting the success of the treatment.

Phenotypic characterization and predictive analysis of p.Asp47Asn LDL receptor mutation associated with Familial Hypercholesterolemia in a Chilean population.

BACKGROUND: Familial hypercholesterolemia (FH) is an inherited disorder mainly caused by mutations in the LDL receptor (LDL-R) and characterized by elevation of low-density lipoprotein cholesterol (LDL-C) levels and premature cardiovascular disease. OBJECTIVE: In this study, we evaluated the clinical phenotype of the p.Asp47Asn, described as an uncertain pathogenic variant, and its effect on the structure of LDL-R and ligand interactions with apolipoproteins. METHODS: 27 children and adolescents with suspected FH diagnosis were recruited from a pediatric endocrinology outpatient clinic. Blood samples were collected after 12 h fasting for lipid profile analysis. DNA sequencing was performed for six FH-related genes by Ion Torrent PGM platform and copy number variation by MLPA. For index cases, a familial cascade screening was done restricted to the same mutation found in the index case. In silico analysis were developed to evaluate the binding capacity of LDL-R to apolipoproteins B100 and E. RESULTS: Lipid profile in children and adolescents demonstrated higher LDL-C levels in p.Asp47Asn carriers compared to the wild type genotype. In silico analysis predicted a reduction in the binding capacity of the ligand-binding modules LA1-2 of p.Asp47Asn LDL-R for ApoB100 and ApoE, which was not produced by local structural changes or folding defects but as a consequence of a decreased apparent affinity for both apolipoproteins. CONCLUSION: The clinical phenotype and the structural effects of p.Asp47Asn LDL-R mutation suggest that this variant associates to FH.

ABSTRACT Introduction: Eating habits in school-age children have been associated with cognitive skills and academic performance. Aim: To determine the relationship between eating habits and academic performance in Chilean school-age children. Methods: Cross-sectional study with 733 school-age children. Eating habits were assessed by the frequency of consumption of food groups, mealtimes, cooking skills and if they liked to cook. Grades of math and language subjects were reported. Results: There was a low proportion of healthy consumption frequency (HCF). Girls had a higher HCF of bread (p<0.001), boys had a higher HCF of dairy (p= 0.016). By sex, academic performance in language was different in girls (p= 0.013). HCF of dairy was associated with academic performance in language (p= 0.017) and mathematics (p= 0.035). Eating breakfast was associated with academic performance in mathematics (p= 0.028) and language (p= 0.001). Not consuming cakes and sweet doughs (p= 0.016), French fries, hot dogs and sopaipillas (p= 0.025) was associated with academic performance in mathematics. 29.1% of children had cooking skills, 54.0% being girls (p= 0.006). Having cooking skills was significantly associated with 7 of the 12 food groups analyzed. Conclusion: Eating habits are associated to the academic performance of Chilean school-age children.

Intracellular Presence of Helicobacter pylori and Its Virulence-Associated Genotypes within the Vaginal Yeast of Term Pregnant Women.

BACKGROUND: Helicobacter pylori transmission routes are not entirely elucidated. Since yeasts are postulated to transmit this pathogen, this study aimed to detect and genotype intracellular H. pylori harbored within vaginal yeast cells. METHODS: A questionnaire was used to determine risk factors of H. pylori infection. Samples were seeded on Sabouraud Dextrose Agar and horse blood-supplemented Columbia agar. Isolated yeasts were identified using and observed by optical microscopy searching for intra-yeast H. pylori. Total yeast DNA, from one random sample, was extracted to search for H. pylori virulence genes by PCR and bacterial identification by sequencing. RESULTS: 43% of samples contained yeasts, mainly Candida albicans (91%). Microscopy detected bacteria such as bodies and anti-H. pylori antibodies binding particles in 50% of the isolated yeasts. Total DNA extracted showed that 50% of the isolated yeasts were positive for H. pylori 16S rDNA and the sequence showed 99.8% similarity with H. pylori. In total, 32% of H. pylori DNA positive samples were cagA+ vacAs1a vacAm1 dupA-. No relationship was observed between possible H. pylori infection risk factors and vaginal yeasts harboring this bacterium. CONCLUSION: H. pylori having virulent genotypes were detected within vaginal yeasts constituting a risk for vertical transmission of this pathogen.

In Vitro Incorporation of Helicobacter pylori into Candida albicans Caused by Acidic pH Stress.

Yeasts can adapt to a wide range of pH fluctuations (2 to 10), while Helicobacter pylori, a facultative intracellular bacterium, can adapt to a range from pH 6 to 8. This work analyzed if H. pylori J99 can protect itself from acidic pH by entering into Candida albicans ATCC 90028. Growth curves were determined for H. pylori and C. albicans at pH 3, 4, and 7. Both microorganisms were co-incubated at the same pH values, and the presence of intra-yeast bacteria was evaluated. Intra-yeast bacteria-like bodies were detected using wet mounting, and intra-yeast binding of anti-H. pylori antibodies was detected using immunofluorescence. The presence of the H. pylori rDNA 16S gene in total DNA from yeasts was demonstrated after PCR amplification. H. pylori showed larger death percentages at pH 3 and 4 than at pH 7. On the contrary, the viability of the yeast was not affected by any of the pHs evaluated. H. pylori entered into C. albicans at all the pH values assayed but to a greater extent at unfavorable pH values (pH 3 or 4, p = 0.014 and p = 0.001, respectively). In conclusion, it is possible to suggest that H. pylori can shelter itself within C. albicans under unfavorable pH conditions.

Plasma from Patients with Rheumatoid Arthritis Reduces Nitric Oxide Synthesis and Induces Reactive Oxygen Species in A Cell-Based Biosensor.

Rheumatoid arthritis (RA) has been associated with a higher risk of developing cardiovascular (CV) diseases. It has been proposed that systemic inflammation plays a key role in premature atherosclerosis development, and is therefore crucial to determine whether systemic components from RA patients promotes endothelial cell-oxidative stress by affecting reactive oxygen species (ROS) and nitric-oxide (NO) production. The aim of this study was to evaluate whether plasma from RA patients impair NO synthesis and ROS production by using the cell-line ECV-304 as a biosensor. NO synthesis and ROS production were measured in cells incubated with plasma from 73 RA patients and 52 healthy volunteers by fluorimetry. In addition, traditional CV risk factors, inflammatory molecules and disease activity parameters were measured. Cells incubated with plasma from RA patients exhibited reduced NO synthesis and increased ROS production compared to healthy volunteers. Furthermore, the imbalance between NO synthesis and ROS generation in RA patients was not associated with traditional CV risk factors. Our data suggest that ECV-304 cells can be used as a biosensor of systemic inflammation-induced endothelial cell-oxidative stress. We propose that both NO and ROS production are potential biomarkers aimed at improving the current assessment of CV risk in RA.

Understanding agricultural water footprint variability to improve water management in Chile.

Understanding water consumption is crucial for sustainable management of water resources. Under climate change scenarios that project highly variable water availability, the need for public policies that assure efficiency and equity in water resources is increasing. This work analyzes the case of the Cachapoal River agricultural basin (34°S 71°W), which presents temperature increases and a precipitation deficit, with a drought period that began more than eleven years ago having significantly decreased water availability. Water consumption in the basin for food production was determined from the agricultural water footprint (WFagricultural), using the green (WFgreen), blue (WFblue) and gray water footprint (WFgray) indicators, which were measured in the upper, middle and lower basin under conditions of climate variability (dry, wet and normal years). The greatest WFagricultural was established in the dry year, with a total of 18,221 m3 t-1, followed by 15,902 m3 t-1 in the wet year and 14,091 m3 t-1 in the normal year. Likewise, the greatest WFblue and WFgray, of 12,000 m3 t-1 and 4934 m3 t-1, respectively, were also observed in the dry year. The greatest WFgreen, 2000 m3 t-1, was calculated for a normal year. The 63% of agricultural area of the basin was covered by avocado (Persea americana), olive (Olea europaea), corn (Zea mays) and grape (Vitis sp) crops, which presented the greatest WFagricultural. This water footprint data provides a quantitative basis for the assessment of water consumption and degradation, considering agricultural production and its multiple variables. The success of the application of these results lies in the use of indicators to understand change processes and complement future water allocation plans with more rational water management models.

Abstracts: Aim: To decribe the profile of users of a health program for chronic diseases (CD), especifically Diabetes Mellitus (DM) and Hypertension (HT), and its relation to indicators of clinical results. Subjects and methods: The subjects had DM and/or HT and were randomly selected form 4 health centers in southern Chile. Questionaires exploring demographic variables, Patient Assessement of Chronic Illness Care (PACIC) measurements of HbA1c, systolic (SBP) and diastolic (DBP) pressures were used as indicators of clinical results. Results: 222 subjects with DM and/or HT were evaluated. Mean age was 53.9 years-old (SD 7.5), 67.6% were females. The prevalence of CD was 53.6% for HT, 31.1% for DM+HT and 15.3% for DM. Mean BP and mean HbA1c were slightly higher in users with DM+HT. As perceived by the patient, the evaluation of care had a mean score 2.61 (SD 1.13). "Design of a method of care delivery / decission support" obtained the highest score. In subjects with HT there was a significant correlation between SBP and the number of drugs being received (p=0.03). Also, a significant correlation between HbA1c and disease duration was found in subjects with DM (p=0.02). In subjects with DM+HT significant correlation (p=0.01) existed between disease duration and both HbA1c and SBP. Conclusion: The evaluation of care suggests the need for a stronger effort in controlling therapeutic measures. Further studies are needed to refine the relation of user profile and clinical results.
