RESUMO

Processing of berries usually degrades anthocyanin and non-anthocyanin phenolics and diminishes antioxidant activity. In Colombia, jelly produced from the fruit of Vaccinium meridionale Swartz is a popular product among consumers. The aim of this study was to determine the effect of jelly processing steps on bioactive components. Analysis of anthocyanins (ACNs) and non-anthocyanin phenolics was performed via HPLC-PDA. Antioxidant activity was assessed by the ORACFL method. The pulping step had the highest impact on ACNs, whose total content was significantly higher in the pomace (747.6 ± 59.2 mg cyanidin 3-glucoside (cyn 3-glu)/100 g) than in the pulp (102.7 ± 8.3 mg cyn 3-glu/100 g). Similarly, pulping caused a significant decrease in flavonols, procyanidins (PACs) and ORACFL values. Despite the effects of processing, Colombian bilberry jelly can be considered a good source of phenolic compounds with high antioxidant activity. The final concentration of ACNs, hydroxycinnamic acids (HCAs) and flavonols, as well as the ORACFL values in this product were comparable to those of fresh cranberry (Vaccinium oxycoccos) and black currant (Ribes nigrum). The results also suggest that the pomace of V. meridionale can be recovered as an excellent source of bioactive compounds.

RESUMO

INTRODUCTION: Eosinophilic cholecystitis (EC) is rarely seen in the pediatric population. Most of the available literature comes from adult patients, while only anecdotal cases have been reported in children. OBJECTIVE: To describe the clinical course, management, and outcomes of all EC cases treated at a children's hospital. MATERIAL AND METHODS: All cholecystectomy specimens obtained between 2011 and 2017 were retrospectively reviewed. EC was diagnosed when more than 90% of the inflammatory cells in the gallbladder wall were eosinophils, whereas lymphoeosinophilic cholecystitis (LEC) was diagnosed when the percentage of eosinophils was between 50 and 90. We analyzed all clinical aspects of patients with EC and LEC. RESULTS: We identified and reviewed 134 cholecystectomy specimens. Of them, 8 (6.0%) were classified as EC, and 3 (2.2%) as LEC. The mean age at presentation was 12.6 (2-17) years. The female-to-male ratio was 1.5/1. One patient had a history of hereditary spherocytosis, and 3 patients had systemic eosinophilia. All patients presented with clinical and radiological signs of acute cholecystitis and underwent cholecystectomy. Acute cholecystitis was confirmed by histopathology in all cases. All cases of EC and LEC had cholelithiasis. None of the patients required additional treatment. All patients recovered uneventfully. CONCLUSIONS: EC is rarely seen in children, it does not have a specific clinical presentation, and it is always associated with cholelithiasis. The diagnosis is made postoperatively by histopathology. All patients in our study presented with acute cholecystitis. TYPE OF STUDY: Retrospective review. LEVEL OF EVIDENCE: Level IV.

RESUMO

Berries of Vaccinium meridionale Swartz contain a variety of phytochemicals, which are believed to account for their bioactive properties. The potential of Vaccinium meridionale Swartz pomace as a source of bioactive compounds was investigated. The dietary fiber (DF) content was assessed by the AOAC method, phenolic compounds were characterized and quantified via HPLC-PDA and UPLC-QTOF-MS. The in vitro antibacterial activity was tested against Gram-positive and Gram-negative bacteria. The antioxidant properties were assessed by the ORAC and the ABTS assays. The DF content was 52.4 ± 3.7%, phenolic compounds comprised anthocyanins (ACNs) (747.6 ± 167.5 mg cyanidin-3-glucoside/100 g FW), hydroxycinammic acids (HCAs) (229.2 ± 68.4 mg chlorogenic acid equivalents/100 g FW), flavonols (335.0 ± 139.5 rutin equivalents/100 g FW), and procyanidins (PACs) (140.9 ± 33.3 mg cocoa procyanidin equivalents/100 g FW). Staphylococcus aureus was more sensitive than E. coli. The ORAC value was 250.0 ± 32.0 µmol TE/g fresh weight (FW). Results suggest that the residue from V. meridionale S. can be utilized to obtain valuable nutraceuticals for the development of functional foods.

RESUMO

Retinoblastoma represents 3% of cancers in children under fifteen years of age. The standard paediatric treatment for saving the affected eye is supraselective intra-arterial chemotherapy performed in interventional rooms. In order to address the radiation toxicity due to the angiography, the aim of this study was to determine the typical dose value corresponding to the procedure, estimate the paediatric patients' eye lens dose and study the relationship between dose indicators and dose to the lens. An automatic dose management software was installed in two interventional rooms to obtain the distribution of the dose indicators kerma-area product and reference-point air kerma, getting a typical value 16 Gy·cm2 and 130 mGy, respectively (n = 35). The eye lens dose estimates were obtained with photoluminescent dosimeters placed on the patient's eyelids. In the left eye, the entrance surface air kerma was 44.23 ± 2.66 mGy, and 12.72 ± 0.89 mGy in the right eye (n = 10). There was a positive correlation between dose to the lens per procedure and dose indicators, with R2 > 0.65 for both eyes. Based on this information, the threshold for the onset of radiation-induce cataracts (500 mGy) will be exceeded if the treatment is performed for more than 8 sessions.

RESUMO

Thyroid hormones (THs) are well known for their genomic effects but recently attention has focused also on their nongenomic actions as rapid modulators of membrane receptors. Here we show that thyroxine (T4) and 3,3',5'-l-triiodothyronine (T3) rapidly decrease N-methyl-d-aspartate (NMDA)-evoked currents in rat hippocampal cultures with potency in the micromolar range. The effect is not mediated by glutamate or glycine binding sites as an increase in agonist or glycine concentration does not alter TH potencies. Furthermore THs' effect on NMDA receptors is independent of voltage and of subunit composition. The mechanism of THs' antagonistic effect does not involve PKC phosphorylation of NMDA receptors since neither blocking nor stimulating PKC changed THs' modulation. T3, but not T4, inhibits also kainate-evoked currents in hippocampal neurons in culture. In hippocampal pyramidal neurons in slice, T3, but not T4, significantly reduced the frequency of miniature excitatory postsynaptic currents (mEPSCs) without affecting their amplitude and decay. In cultured rat cortical neurons THs prevented glutamate-induced neuronal death at concentrations similar to those effective on glutamatergic receptors. Taken together our data show for the first time that THs can rapidly affect ionotropic glutamatergic receptors in hippocampal neurons, an effect that could have an important role in their modulation of brain function in physiological and pathological states.

RESUMO

Berries of Colombian Euterpe oleracea Mart. were analyzed for total phenolic content (TPC), anthocyanin (ACN) content, and antioxidant activity. Additionally, reversed-phase ultra-high performance liquid chromatography with photodiode array detection (RP-UHPLC-PDA) and heated electrospray ionization (HESI) multistage mass spectrometry (MS(n)) were used to determine the composition of phenolic compounds. Anthocyanin content was 0.57±0.39mg cyanidin-3-glucoside/g fresh weight (FW) and TPC was 6.07±2.17mg gallic acid equivalent (GAE)/g FW. The ABTS radical scavenging activity was 3.1±1.3µmol Trolox equivalents (TE)/100g FW, whereas the DPPH value was 2693.1±332.8µmol TE/100g FW. Overall, results show that Colombian açai has a more diverse polyphenolic profile and higher antioxidant activity than Brazilian açai. This information could be useful in authentification procedures to differentiate Brazilian açai from Colombian açai when used as an alternative for the supply of this fruit during the time of shortage in Brazil.

RESUMO

INTRODUCTION: There is evidence of increased macro- and micro-vascular risk in diabetic patients. The objective of this study was to determine the level of control in patients in different population groups with type 2 diabetes. DESIGN: Descriptive cross-sectional study. LOCATION: Primary care. Madrid Health Service. Year: 2014. SUBJECTS: Patients over 14 years with type 2 diabetes. Number of patientes: n=6674. MEASUREMENTS: Variables on the degree of control (HbA1c, systolic blood pressure [SBP], diastolic blood pressure [DBP], LDL-c) and variables on patient characteristics (demographic, other cardiovascular risk factors, complications). RESULTS: The mean age of patients with controlled HbA1c was 67.8 years vs. 62.9 years in the uncontrolled (P<.001). Patients diagnosed with hypertension have a higher percentage of control with respect to the undiagnosed in HbA1c, SBP, DBP and LDL-c: 51 vs. 37%, 62 vs. 43%, 75 vs. 47% and 57 vs. 44% respectively; diagnosed with dyslipidaemia: 51 vs. 39%, 60 vs. 49%, 70 vs. 56% and 56 vs. 46%. With a diagnosis of macroangiopathy: 46 vs. 45%, 58 vs. 54%, 71 vs. 62% and 15 vs. 60%. All differences were statistically significant (P<.001). Over 50% of patients without a diagnosis of hypertension had an SBP> 140mmHg or DBP> 90mmHg. Over 25% of patients with hypertension or DL and uncontrolled levels were not receiving drug treatment. CONCLUSION: Control was improved in all groups, especially in younger patients, with particularly high cardiovascular risk by the presence of other cardiovascular risk factors or macroangiopathy. A significant percentage of patients with uncontrolled BP and cLDL were not diagnosed or receiving drug treatment.

RESUMO

INTRODUCTION: There is evidence that cardiovascular goals are beneficial in diabetes. OBJECTIVE: To determine the distribution of cardiovascular risk levels in patients with diabetes and the clinical interventions they have received. DESIGN: Descriptive cross-sectional study. SETTING: SERMAS (Madrid) 2010. SUBJECTS: All patients with diabetes. (n=41,096). MAIN MEASUREMENTS: Patients in primary or secondary prevention, metabolic and cardiovascular risk factors control, pharmacological and non-pharmacological interventions. Patient and professional variables. RESULTS: Around one-fifth (21.5%) (95%CI: 21.1% -21.9%) in secondary prevention (very high cardiovascular risk). HbA1c was under control in 31% (95%CI: 30.1%-32%), with 49.9% (95%CI: 48.8%-50.9%) with BP under control, and 39.4% (95% CI: 38.4%-40.4%) with LDL controlled. Only 8.9% (95%CI: 8.3%-9.5%) had a well-controlled HdA1c, BP and LDL, and in 19.8% (95%CI: 19%-20.6%) none of these were under control. Of those with an uncontrolled BP, 23.6% (95% CI: 23.2%-24%) had antihypertensive drugs. There was better control in patients older than 70 years, and those who lived in an urban center, or a lower number of patients per day. CONCLUSION: In diabetic patients with very high cardiovascular risk (secondary prevention), just half of them had good control of cardiovascular risk factors (BP and LDL). An association was found between better control and older than 70, urban center or lower number of patients per day. This suggests developing strategies to promote a comprehensive control of cardiovascular risk factors in diabetic patients in secondary prevention.

RESUMO

The contents and profile of polyphenols were analyzed in edible petals of nasturtium flowers (Tropaeolum majus) of three colors, and their oxygen radical absorbance capacities (ORAC) were compared. Three primary anthocyanins (ACNs) and 15 non-ACN phenolic compounds including hydroxycinammic acids (HCAs) and flavonoids (myricetin, quercetin, and kaempferol derivatives) were detected. Anthocyanin concentration was within 31.9 ± 21.7 and 114.5 ± 2.3 mg cyanidin-3-glucoside (cy-3-glu)/100 g fresh weight (FW) in yellow and red petals, respectively. The concentration of HCAs varied between 33.3 ± 7.1 and 235.6 ± 8.1 mg chlorogenic acid equivalents/100 g FW for red and yellow flowers, respectively. Red flowers had the highest level of flavonoids (315.1 ± 2.4 mg myricetin equivalents/100 g FW) and the highest ORAC radical-scavenging activity. These results show the diversity and abundance of polyphenolic compounds in nasturtium flowers, which could be the basis for applications in functional foods, cosmetics, and pharmaceuticals.

RESUMO

PURPOSE: The aim of this study was to review the biliary complications occurring in late follow-up after liver transplantation in children. METHODS: The medical records of 135 children who received orthotopic liver transplantations (OLT) and had graft survival of more than 1 year were reviewed. Technical variants using a reduced-size graft were applied in 32 (23.7%). For biliary reconstruction, 15 patients had choledochocholedochostomy and 120 a Roux-en-Y loop. Biliary reoperation in the early post-OLT period was needed in 24 patients (17.7%). Routine checking of liver function and duplex Doppler ultrasonography (DDS) were performed during the follow-up period, which averaged 58 months. Late biliary complication was defined as that occurring after the first hospital discharge. RESULTS: Late biliary complications occurred in 18 children (13.3%); 16 showed symptoms or analytical disturbances in liver function tests. The Diagnoses included uncomplicated cholangitis (n = 6), anastomotic biliary stricture (n = 7), ischaemic damage of the biliary tree (n = 3) including one late (28 months) hepatic artery thrombosis leading to an intrahepatic biloma. and bile leak after T-tube removal (n = 2). The six children with uncomplicated cholangitis had no repeat episodes in follow-up despite persistent aerobilia. Six patients affected by anastomotic strictures were treated successfully with percutaneous dilatation and, if present, stone removal. Persisting dysfunction and cholangitis occurred in one case affected by ischaemic biliary disease. Biliary leaks after T tube removal settled spontaneously. Risk factors for late biliary complications were determined. There was no relation to the cold ischaemia time, type of graft or biliary reconstruction, or previous early post-OLT biliary reoperation. Aerobilia (affecting 21.5% of OLT patients) was related to cholangitis (P = .001). CONCLUSIONS: Anastomotic strictures, reflux of intestinal contents via the Roux-en-Y loop, and residual ischaemic damage led to late biliary complications in 12% of paediatric OLT patients. Evidence of biliary dilatation on DDS may be delayed in anastomotic strictures; in these cases the results of percutaneous treatment were excellent. Children with aerobilia have and increased risk of cholangitis.

RESUMO

A 68-year-old man with peripheral vascular disease and associated risk factors, was diagnosed by CT-scan and aortography with an atherosclerotic descending thoracic aortic aneurysm. The patient was treated by successful endovascular grafting of the aneurysm using a midsternotomy incision and the insertion of a thoracic stent-graft through a T-Dacron tube sutured in the ascending aorta, without the aid of cardiopulmonary bypass.

RESUMO

UNLABELLED: In the long-term after liver transplantation (LT), some children develop prehepatic portal hypertension (PPH) and raise problems not very well known yet; many of the lessons learned with the management of these patients may be useful outside the LT. AIM: 1. To analyze the incidence and risk factors of PPH after LT. 2. To evaluate the results with the different treatments used. METHODS: Retrospective study over 164 children surviving more than 1 year after LT. Univariant analysis of possible risk factors associated and multivariant (logistic regression), for those that had significance in the univariant analysis. Other factors associated are analyzed as well as the indications and results of two types of treatment: percutaneous pneumatic dilatation and surgical shunt (splenorenal and Rex shunt). RESULTS: 9 children developed symptomatic PPH (hemorrhage in 8, ascites in 1), associated to lymphoproliferative post-LT disease in 2, and to anastomotic biliary stricture in 1. The age at first LT (children under 1 year old), weight (below 10 kg), and need of retransplantation (reLT) were in the univariant analysis the associated variables with increased risk of PPH. The diagnosis (biliary atresia) and the emergency status of the LT were almost significative. In the multivariant analysis, the need of reLT is the only independent variable that increases the risk (relative risk: 4.5, confidence interval 95%: 1.29-18.87). At diagnosis 3 cases showed portal estenosis, and 5 showed absence of permeability with cavernomatous transformation. The PPH was caused in one case because of the esplenic vein disconnection (treatment not required at the moment); the three cases of portal estenosis were dilated percutaneously with success, and 2 of the 5 cases with portal thrombosis have been surgically shunted: one by an splenorenal shunt and the other by a Rex shunt (first case done in Spain); the other 3 cases are stable waiting for a surgical solution. The hepatic function is normal in the 9 cases. CONCLUSIONS: The PPH can complicate the prognostic of the pediatric LT in the long term. The treatment depends on the permeability of the portal trunk. Whenever possible, percutaneous dilatation should be attempted; should surgery be required, the Rex shunt is the best option.

RESUMO

AIM: 1. To show how in a program of pediatric liver transplantation (PLT) with 12 years of experience, the continuous use of technical innovations has allowed to improve the results and to treat the most complex cases. 2. To point out that when the immediate results of the transplant improve and the evolution time get longer, the late complications become the main source of concern. MATERIAL AND METHODS: The graft survival and the incidence of early surgical complications was compared between the first 100 PLT and the last 100 PLT (Total 235 PLT). The patients survival was also compared between the first and the last 5 years. In every case it was analyzed the age and weight of the children at the time of the transplant and the type of graft (full or reduced liver). The incidence of late complications in the global series was also analyzed, especially the posttransplant lymphoproliferative disease (PTLD) and the late biliary and vascular complications. RESULTS: There are significant differences between the first 100 PLT and the last 100 PLT in relation with the age of the patients (6.8 +/- 0.6 vs 4.2 +/- 0.5 years), the number of children younger than 1 year (4 vs 28), weight (22.4 +/- 1.2 vs 16.9 +/- 1.7 kg), number of PLT in children under 10 kg (7 vs 43), use of reduction techniques (7 vs 49), rate of hepatic artery thrombosis (12% vs 3%), and rate of early biliary complications (13% vs 4%). The 5 years survival of the graft was 51% in the first 100 PLT vs 65% in the last 100 PLT, and the 5 years patients survival was 70.1% in the first 5 years of the program vs 79.6% in the last 5 years. Among the late complications in the global series, 13 cases of PTLD (2 deaths) have special relevance, 6 cases of late anastomotic biliary stricture, 4 cases of portal stenosis, 1 arterial thrombosis, 1 death due to a fulminant sepsis and another death because of a colitis with multiple hepatic abscess. CONCLUSIONS: 1. The result of PLT improve, despite of the fact that in the last years the difficulty of the surgical procedures have increased (the patients are younger, with less weight and the reduction techniques are used more frequently). 2. The late complications have a significant influence in the prognosis, being that influence not completely established yet.

RESUMO

OBJECTIVE: To study relationship between institutional process indicators (measured using electronic records) and intermediate outcomes of patients with diabetes. METHOD: Cross-sectional epidemiological study. Setting Primary care health district 1. Madrid. 2010. PATIENTS: all patients with diabetes; n = 16.652. Main measures variables. Independent. Institutional process indicators. Dependent. Intermediate outcomes: GHb, BP, LDL, tobacco and weight within target limits and detected complications. Confounding. Age, gender, type and years for DM, co-morbidity, drugs and professional variables. RESULTS: GHb of 55.9% (SE 0,4) of patients was within target limits. Bivariate analysis and multivariate logistic regression showed that the recording of some process indicators was associated with an increase in the probability to achieve targets in intermediate outcomes: reviewing personal and family history, lifestyle and drug therapy, creatinine, GHb, BP and weight measurement, smoking advice, EKG, ankle-arm index, and eye examination. OR were from 1,15 (CI 95%: 1.01-1.32) to 2.05 (CI 95%: 1.76-2.39). Relationship among other indicators and higher probability to achieve targets was not found: classification, reviewing care plan, glucose, BMI, LDL and microalbuminury measurement. CONCLUSIONS: In diabetes, a lot of institutional process indicators measured on electronic records was associated with increase of probability to achieve targets in intermediate outcomes. It suggests to maintain process and outcome measurement, to include other outcomes, to include other interventions, to prioritize improvements in process indicators that show low performance and high impact and to keep out or to change process indicators that relationship was not found.

RESUMO

The fruit of Arazá (Eugenia stipitata McVaugh) native to the Colombian Amazon is considered a potentially economically valuable fruit for the Andean economy due to its novel and unique taste. The fruit has an intense yellow color, but its chemical composition and properties have not been well studied. Here we report the identification and quantitation of carotenoids in the ripe fruit using high performance liquid chromatography (HPLC) with photodiode array detector (PDA) and atmospheric pressure chemical ionization (APcI) mass spectrometry (MS/MS). The qualitative carotenoid profile of the fruit according to maturity stage was also observed. Furthermore, antioxidant activity of the peel and pulp were assessed using the ferric reducing ability of plasma (FRAP), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and 1,1-diphenyl-2-picrylhydrazyl (DPPH) methods, in addition to chemical indexes and total phenolic content. Multiple carotenoids were identified in the peel and pulp including four xanthophylls (free and esterified as their mono and diesters) and two carotenes. One of the xanthophylls was tentatively identified as zeinoxanthin, while the others were identified as lutein, zeaxanthin, and ß-cryptoxanthin. Carotenes included α-carotene and ß-carotene. The total carotenoid content was significantly higher in the peel (2484 ± 421 µg/100 g FW) than in the pulp (806 ± 348 µg/100 g FW) with lutein, ß-cryptoxanthin, and zeinoxanthin as the major carotenoid components. The unique carotenoid composition of this fruit can differentiate it from other carotenoid-rich fruits and perhaps be useful in authentication procedures. Overall, results from this study suggest that Colombian Arazá may be a good edible source of carotenoids important in retinal health as well as carotenoids with provitamin A activity. Therefore, Arazá fruit can be used as a nutraceutical ingredient and in production of functional foods in the Colombian diet.

RESUMO

The stability of anthocyanin (ACN) freeze-dried powders from Andes berry (Rubus glaucus Benth) as affected by storage, addition of maltodextrin as a carrier agent, and illumination was evaluated in isotonic model beverages. The ethanolic ACN extract was freeze dried with and without maltodextrin DE 20. Isotonic model beverages were colored with freeze-dried ACN powder (FDA), freeze-dried ACN powder with maltodextrin (MFDA), and red nr 40. Beverages were stored in the dark and under the effect of illumination. Half life of the ACNs, changes in color, total phenolics content (TPC), and antioxidant activity were analyzed for 71 d. Addition of maltodextrin and absence of light stabilized the color of beverages and improved ACN and TPC stability during storage. The antioxidant activity of the beverages was higher when they were colored with MFDA and highly correlated with ACN content. There was no correlation between antioxidant activity and TPC. It is concluded that addition of maltodextrin DE 20 as a carrier agent during freeze-drying improves the color and stability of nutraceutical antioxidants present in Andes berry extract. This suggests a protective enclosing of ACNs within a maltodextrin matrix with a resulting powder that could serve as a supplement or additive to naturally color and to enhance the antioxidant capacity of isotonic beverages.

RESUMO

Anthocyanins, total phenolic content, ascorbic acid content, and the antioxidant activity were determined in extracts of Andes berry fruit (Rubus glaucus Benth). Anthocyanis (ACNs) were isolated and characterized by means of high-performance liquid chromatography (HPLC) with photodiode array detection and electro spray ionization/mass spectrometry (PDA-ESI/MS/MS) analysis. The anthocyanin (ACN) content was 45 mg/100 g FW. The isolated anthocyanins were characterized as cyanidin 3-sambubioside, cyanidin 3-glucoside, cyanidin 3-xylorutinoside, cyanidin 3-rutinoside, pelargonidin 3-glucoside, and pelargonidin 3-rutinoside. The ascorbic acid content was 10.1 mg/100 g FW. The total phenolic content as determined by the Folin-Ciocalteau method was 294 mg GAE/100 g FW while the antioxidant activity as measured by ABTS(.) (+) radical scavenging capacity and ferric reducing antioxidant power (FRAP) was 2.01 and 4.50 mmol TE/100 g FW or 8.22 mmoles ferric iron reduced/100 g FW, respectively. The high phenolic content and antioxidant capacity of Andes berry suggest that this fruit could be a rich source of natural pigments, nutraceuticals, and natural antioxidants.

RESUMO

Esta investigación de corte cualitativo con diseño fenomenológico, buscó a través de los talleres lúdicos, la observación participante y la entrevista semiestructurada, comprender el significado de las vivencias de niños y niñas de 7 a 16 años de edad afectados por el VIH/SIDA, adscritos a un centro de atención y apoyo para el VIH/SIDA, entendiendo la vivencia como el resultado de la relación del sujeto con los diversos objetos y eventos que constituyen los aspectos dinámicos de su mundo y que componen su historia. Los significados de estos niños/as acerca de la vivencia de estar afectados por el VIH/SIDA giran en torno al señalamiento, la discriminación, el ser portador social del virus, miedo de revelar la condición en la escuela por el rechazo que puede causarles, la no satisfacción de sus demandas ontológicas por su institucionalización y la resignificación de sus vivencias que los lleva a tener conductas preventivas y ser educadores de la enfermedad.


This qualitative research with a phenomenological design, searched throughout playful workshops, partaker observation and semi-structured interview, understand the meaning of the experiences of children from 7 to 16 years old affected by HIV/AIDS, care for a support center for HIV/AIDS. Understanding the experience as the result of the subject's relationship with the different objects and events that constitute the dynamic aspects of their world and that comprise their story. The meanings of these children on the experience of being affected by HIV/AIDS revolve around tagging, discrimination, carrying the virus socially, fear to reveal the condition at school that can cause rejection, the failure to meet their ontological demands for their institutionalization and the significance of their experiences that leads to preventive behaviors and develop educators of the disease.
