The Role of Social Support and Sleep Quality in the Psychological Well-Being of Nurses and Doctors.

Social support enhances the development of adaptive strategies to cope with difficulties, which may affect psychological well-being. Sleep quality has been highlighted as having a relevant role in psychological well-being. The present study aimed to analyse the role of social support and sleep quality in the psychological well-being of health professionals (nurses and doctors) compared to the general population. The sample comprised 466 adults aged between 18 and 75 (M = 43.4; SD = 10.8), of which 272 were the general population and 194 nurses and doctors. Data were collected through a Sociodemographic Questionnaire, the Multidimensional Scale of Perceived Social Support, the Pittsburgh Sleep Quality Index, and the Psychological Well-Being Manifestation Measure Scale. Nurses presented less balance (also doctors), sociability and happiness than other professionals. Less significant sociability was observed in nurses compared with doctors. The results also allowed us to observe the positive role of social support from significant others on social involvement and sociability and the positive role of the family in self-esteem. Social support from friends played a positive role in all dimensions of psychological well-being. Males had a higher prevalence of psychological well-being. Other professionals and sleep quality show high levels of psychological well-being in all dimensions. Data discussion highlights the role of social support, sleep, and sex and the implications of health professions (nurses and doctors) on psychological well-being.

Immunochromatographic POC-CCA Test for the diagnosis of intestinal schistosomiasis in a high endemic region in Brazil: Differences in the interpretation of results.

The POC-CCA test is subject to variations in reading interpretations depending on the intensity of its results, and trace test reading have implications for determining prevalence. The aim of this study was to assess whether the readings obtained from the POC-CCA tests, conducted using a semi-quantitative scale (the G-score classification for test determination), exhibited concurrence with the direct visual interpretation (positive, negative, or trace) performed by two distinct analysts, using photographs from previously performed POC-CCA test carried out in the municipality of Maruim, in the state of Sergipe-Brazil, a region of high endemicity. The devices used to read the photographs were smartphones, so as to simulate field usage, and a desktop, a tool with higher image quality that would help the researchers in the evaluation and establishment of the final result at a later. In direct visual interpretation of the POC-CCA photographs, the most discordant results occurred in the identification of the trace response (T). The Kappa index established for the direct visual interpretation between the two analysts, in which T is considered as positive, in the desktop was κ=0.826 and in the smartphone, κ=0.950. When we use the G-score as a reading standardization technique and classify the results according to the manufacturer, with trace being evaluated as positive, the highest level of agreement was obtained. Some disagreement remains between the direct visual interpretation and the G-score when performed on the desktop, with more individuals being classified as negative in the direct visual interpretation, by both analysts. However, this result was not statistically significant. The use of the G-score scale proved to be an excellent tool for standardizing the readings and classifying the results according to the semi-quantitative scale showed greater concordance of results both among analysts and among the different devices used to view the photographs.

Subclinical signs of podocyte injury associated with Circulating Anodic Antigen (CAA) in Schistosoma mansoni-infected patients in Brazil.

BACKGROUND: The long-term effects of schistosomiasis on the glomerulus may contribute to the development of chronic kidney disease. This study aimed to investigate baseline Schistosoma mansoni-Circulating Anodic Antigen (CAA) levels and their association with kidney biomarkers related to podocyte injury and inflammation in long-term follow-up after praziquantel (PZQ) treatment. METHODS: Schistosoma infection was diagnosed by detecting CAA in urine using a quantitative assay based on lateral flow using luminescent up-converting phosphor reporter particles. A cutoff threshold of 0.1 pg/mL CAA was used to diagnose Schistosoma infection (baseline) in a low-prevalence area in Ceará, Northeast, Brazil. Two groups were included: CAA-positive and CAA-negative individuals, both of which received a single dose of PZQ at baseline. Urinary samples from 55 individuals were evaluated before (baseline) and at 1, 2, and 3 years after PZQ treatment. At all time points, kidney biomarkers were quantified in urine and adjusted for urinary creatinine levels. RESULTS: CAA-positive patients had increased baseline albuminuria and proteinuria and showed greater associations between kidney biomarkers. CAA levels correlated only with Vascular Endothelial Growth Factor (VEGF) (podocyte injury) levels. Increasing trends were observed for malondialdehyde (oxidative stress), monocyte chemoattractant protein-1 (inflammation marker), and VEGF. In the follow-up analysis, no relevant differences were observed in kidney biomarkers between the groups and different periods. CONCLUSIONS: S. mansoni-infected individuals presented subclinical signs of glomerular damage that may reflect podocyte injury. However, no causal effect on long-term renal function was observed after PZQ treatment.

Accuracy of the urine point-of-care circulating cathodic antigen assay for diagnosing Schistosomiasis mansoni infection in Brazil: A multicenter study.

BACKGROUND: The World Health Organization recommends a market-ready, urine-based point-of-care diagnostic test for circulating cathodic antigens (CCA) to determine the prevalence of S. mansoni. This study evaluated the performance of the URINE CCA (SCHISTO) ECO TESTE® (POC-ECO), which is currently available in Brazil. METHODS: Residents from eight sites with different prevalence estimates provided one urine sample for POC-ECO and one stool sample for Kato-Katz (KK) and Helmintex® (HTX) testing as an egg-detecting reference for infection status. RESULTS: None of the study sites had significantly higher POC-ECO accuracy than KK. CONCLUSIONS: POC-ECO is not currently recommended in Brazilian schistosomiasis elimination programs.

Application of Poly-L-Lysine for Tailoring Graphene Oxide Mediated Contact Formation between Lithium Titanium Oxide LTO Surfaces for Batteries.

When producing stable electrodes, polymeric binders are highly functional materials that are effective in dispersing lithium-based oxides such as Li4Ti5O12 (LTO) and carbon-based materials and establishing the conductivity of the multiphase composites. Nowadays, binders such as polyvinylidene fluoride (PVDF) are used, requiring dedicated recycling strategies due to their low biodegradability and use of toxic solvents to dissolve it. Better structuring of the carbon layers and a low amount of binder could reduce the number of inactive materials in the electrode. In this study, we use computational and experimental methods to explore the use of the poly amino acid poly-L-lysine (PLL) as a novel biodegradable binder that is placed directly between nanostructured LTO and reduced graphene oxide. Density functional theory (DFT) calculations allowed us to determine that the (111) surface is the most stable LTO surface exposed to lysine. We performed Kubo-Greenwood electrical conductivity (KGEC) calculations to determine the electrical conductivity values for the hybrid LTO-lysine-rGO system. We found that the presence of the lysine-based binder at the interface increased the conductivity of the interface by four-fold relative to LTO-rGO in a lysine monolayer configuration, while two-stack lysine molecules resulted in 0.3-fold (in the plane orientation) and 0.26-fold (out of plane orientation) increases. These outcomes suggest that monolayers of lysine would specifically favor the conductivity. Experimentally, the assembly of graphene oxide on poly-L-lysine-TiO2 with sputter-deposited titania as a smooth and hydrophilic model substrate was investigated using a layer-by-layer (LBL) approach to realize the required composite morphology. Characterization techniques such as X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), Kelvin probe force microscopy (KPFM), scanning electron microscopy (SEM) were used to characterize the formed layers. Our experimental results show that thin layers of rGO were assembled on the TiO2 using PLL. Furthermore, the PLL adsorbates decrease the work function difference between the rGO- and the non-rGO-coated surface and increased the specific discharge capacity of the LTO-rGO composite material. Further experimental studies are necessary to determine the influence of the PLL for aspects such as the solid electrolyte interface, dendrite formation, and crack formation.

High schistosomiasis-related mortality in Northeast Brazil: trends and spatial patterns.

BACKGROUND: We analyzed the trends and spatial patterns of schistosomiasis-related mortality in Northeast Brazil in 2000-2019. METHODS: A mixed population-based ecological study was conducted, using information on the underlying or associated causes of death. We used Joinpoint regression analysis to calculate the trends. The spatial analysis included rates, spatial moving averages, and standardized mortality rates. The spatial dependence analysis was based on Getis-Ord's G and Gi* indices (Gi star) and local Moran's index to check for autocorrelation. RESULTS: A total of 5,814,268 deaths were recorded, of which 9,276 (0.16%) were schistosomiasis-related; 51.0% (n=4,732, adjusted rate 0.90/100,000 inhabitants [95% confidence interval (CI) 0.88-0.93]) were males; 40.0% (n=3,715, adjusted rate 7.40/100.000 inhabitants [95%CI: 7.16-7.64]) were ≥70 years old; 54.8% (n=5,087, crude rate 0.80/100,000 inhabitants) were of mixed/Pardo-Brazilian ethnicity; and 77.9% (n=7,229, adjusted rate 0.86/100,000 inhabitants [95%CI: 0.84-0.88]) lived outside state capitals. The highest proportion of deaths was in the state of Pernambuco (53.9%, n=4,996, adjusted rate 2.72/100,000 inhabitants [95%CI: 2.64-2.79]). Increasing mortality rate was verified in the state of Sergipe. On the coast of the state of Rio Grande do Norte and Bahia, there was spatial dependence of spatio-temporal risk patterns with clusters. Throughout the study period, we found positive spatial autocorrelation and cluster formation. CONCLUSIONS: In Northeast Brazil, schistosomiasis persists with a high mortality rate, especially in the coastal region, with heterogeneous spatial and temporal patterns. To eliminate schistosomiasis by 2030, it is necessary to strengthen the financing and management of the unified health system (SUS).

Kidney injury biomarkers and parasitic loads of Schistosoma mansoni in a highly endemic area in northeastern Brazil.

Schistosomiasis affects approximately 240 million people worldwide. In Brazil, it is estimated that 1.5 million people are infected with Schistosoma mansoni and up to 15% of diagnosed individuals develop kidney damage. Renal involvement in schistosomiasis mansoni is characterized by glomerular lesions, with a high incidence, especially in chronically infected patients living in areas of high endemicity. Renal damage occurs slowly and is often asymptomatic, with a long-term manifestation of chronic kidney disease, with progressive loss of kidney functions, and early detection of subclinical kidney disease is of great importance. The aim of this study was to investigate kidney damage in patients infected with S. mansoni through urinary biomarkers of kidney injury and their association with the different parasite loads found. The patients were divided into two groups based on the diagnosis of infection by S. mansoni by the Kato-Katz and IgG-ELISA-SEA method: group of individuals infected by S. mansoni, Kato-Katz positive (PG); and group of individuals not infected by S. mansoni, Kato-Katz-negative (NG). Urinary creatinine and albuminuria were determined by immunoturbidimetry and proteinuria by the colorimetric method. The urinary biomarkers of podocyte injury (VEGF and Nephrin) and glomerular inflammation (MCP-1) were quantified by immunoassay and expressed by the urinary creatinine ratio. Urinary VEGF showed significantly higher levels in PG compared to NG (p = 0.004), increasing at all intensities of infection including low parasite load (p = 0.020). Our results show increased signs of podocyte damage in patients with schistosomiasis mansoni regardless of the parasite load, evidenced by increased urinary VEGF levels. However, further studies are needed since data related to schistosomiasis glomerulopathy and its association with new urinary biomarkers of kidney injury are scarce in the literature.

Why do patients leave the Pediatric Emergency Department and what happens to them?

BACKGROUND: The dropout rate is an important indicator of the quality of emergency services. The authors intend to evaluate factors that influence abandonments in the Pediatric Emergency Department (PED) and to assess outcome and destination of the highest triage leveled patients. METHODS: Retrospective analysis of the abandonment cases occurring between 2014 and 2016 in a tertiary hospital, including sociodemographic characterization, temporal factors, triage level, referral from other health services, waiting time and patient attendance. The outcome of the highest triage level was also accessed. RESULTS: In the three years analyzed, there were 240171 PED visits, with an abandonment rate of 2.57%. PED abandonment was influenced by higher patient attendance and waiting time, a younger age, and less urgent triage level. Only 1.78% of the urgent or emergent patients (level three or two) abandoned the PED. Of these, 44% sought medical care in the next five days, 41% of which in private institutions, 40% in public hospitals and 19% in primary care. Only 0.81% of those were hospitalized. CONCLUSIONS: The majority of patients who leave the PED do not correspond to urgent cases. Health education awareness campaigns, clinical counseling platforms (online or phone services) and the improved accessibility of primary health care may optimize the usage of health resources. The reinforcement of the teams in times of greater affluence may contribute to decrease the rate of abandonment.

Persistence of Schistosomiasis-Related Morbidity in Northeast Brazil: An Integrated Spatio-Temporal Analysis.

OBJECTIVE: To analyze the temporal trend and spatial patterns of schistosomiasis-related morbidity in Northeast Brazil, 2001-2017. METHODS: Ecological study, of time series and spatial analysis, based on case notifications and hospital admission data, as provided by the Ministry of Health. RESULTS: Of a total of 15,574,392 parasitological stool examinations, 941,961 (6.0%) were positive, mainly on the coastline of Pernambuco, Alagoas and Sergipe states. There was a reduction from 7.4% (2002) to 3.9% (2017) of positive samples and in the temporal trend of the detection rate (APC-11.6*; Confidence Interval 95%-13.9 to -9.1). There was a total of 5879 hospital admissions, with 40.4% in Pernambuco state. The hospitalization rate reduced from 0.82 (2001) to 0.02 (2017) per 100,000 inhabitants. CONCLUSION: Despite the reduction in case detection and hospitalizations, the persistence of focal areas of the disease in coastal areas is recognized. This reduction may indicate a possible positive impact of control on epidemiological patterns, but also operational issues related to access to healthcare and the development of surveillance and control actions in the Unified Health System.

Diagnostic comparison of stool exam and point-of-care circulating cathodic antigen (POC-CCA) test for schistosomiasis mansoni diagnosis in a high endemicity area in northeastern Brazil.

This study aimed to evaluate the performance of the point-of-care circulating cathodic antigen (POC-CCA) test in a highly endemic area in Brazil, comparing it to the Kato-Katz (KK) technique for sensitivity, specificity and the intensity of the reaction of the test in relation to the parasitic load. The community in Sergipe, Brazil, participated in the study, providing three stool samples, one of urine (POC-CCA) and fingers tick blood sample was tested by enzyme-linked immunosorbent assay (ELISA). Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, kappa coefficient and Spearman's correlation were calculated for the POC-CCA test using the KK as the reference. The prevalence of schistosomiasis by KK testing was 48.82%; POC-CCA (t+) 66.14%; POC-CCA (t-) 45.24%. ELISA results showed 100% agreement in individuals with high and moderate eggs per gram (EPG). POC-CCA presented good diagnostic performance in individuals with medium and high EPG, but there were a high number of false negatives in individuals with low intensity infections. As observed, POC-CCA-filter test improves accuracy and sensitivity compared to a conventional test.

Orofacial clefts associated with cardiac anomalies: 27 years of experience of a multidisciplinary group in a tertiary hospital in Portugal / Fendas orofaciais associadas a anomalias cardíacas: 27 anos de experiência de um grupo multidisciplinar em um hospital terciário em Portugal

AIMS: Orofacial clefts (OFC) are a heterogeneous group of birth defects arising in about 1.7/1000 newborns. They can occur with other congenital anomalies, including heart defects. We aim to describe a population with orofacial clefts and associated cardiac anomalies. METHODS: Retrospective study of patients attended in the Cleft Lip and Palate Multidisciplinary Group outpatient clinic at Hospital Universitario São João, Porto-Portugal. Medical records from January 1992 through December 2018 were reviewed. Patients were divided into four groups according to the Spina classification: cleft lip (CL), cleft lip and palate (CLP), isolated cleft palate (CP) and atypical cleft (AC). Further categorization included gender, affected relatives, associated congenital anomalies and syndromes. RESULTS: From the 588 patients included, 77 (13%) presented cardiac anomalies. Of those with orofacial cleft and cardiac anomalies, 53% were males and 17% had known affected relatives. CP was the most common cleft among patients with cardiac anomaly (~56%). Additional congenital anomalies were found in 89.7% of patients, namely facial defects, central nervous system, renal and skeletal malformations. A recognizable syndrome was identified in 61.5%, being Pierre-Robin the most common (n=22), followed by 22q11.2 microdeletion (n=9). Bothadditional congenital anomalies and recognizable syndromes were significantlymore prevalent in patients with heart disease (p<0.05). The main groups of cardiac anomalies were left-to-right shunt (n=47) and right ventricular outflow tractobstruction (n=14). From these, 26 had a ventricular septal defect, 15 atrial septal defect and seven patients had tetralogy of Fallot. Five patients had dysrhythmias. CONCLUSIONS: Due to the high prevalence of cardiac anomalies in the cleft population, a routine cardiac evaluation should be performed in all these patients.

INTRODUÇÃO: As fendas lábio-palatinas são um grupo heterogêneo de defeitos congênitos que ocorrem em cerca de 1,7 / 1000 recém-nascidos. Eles podem ocorrer com outras anomalias congênitas, incluindo defeitos cardíacos. O nosso objetivo é descrever uma população com fendas lábio-palatinas e anomalias cardíacas associadas. MÉTODOS: Estudo retrospectivo de doentes seguidos pelo Grupo Multidisciplinar de Fendas Lábio-Palatinas no Hospital Universitário São João, Porto-Portugal. Foram analisados os prontuários médicos de janeiro de 1992 a dezembro de 2018. Os doentes foram divididos em quatro grupos, de acordo com a classificação de Spina: fenda labial (CL), fenda labial e palatina (CLP), fenda palatina isolada (PC) e fenda atípica (CA). Outras categorizações incluíram sexo, parentes afetados, anomalias e síndromes congênitas associadas. RESULTADOS: Dos 588 pacientes incluídos, 77 (13%) apresentaram anomalias cardíacas. Daqueles com fenda e anomalias cardíacas, 53% eram do sexo masculino e 17% tinham parentes afetados. A PC foi a fenda mais comum entre os doentes com anomalia cardíaca (aproximadamente 56%). Anomalias congénitas adicionais, como defeitos faciais, malformações do sistema nervoso central, renais e esqueléticas foram encontradas em 89,7%. Síndromes foram identificadas em 61,5%, sendo Pierre-Robin a mais comum (n = 22), seguida pela microdeleção 22q11.2 (n = 9). Anomalias congénitas adicionais e a presença de uma síndrome genética foram significativamente mais prevalentes em doentes com doença cardíaca associada (p <0,05). Os principais grupos de anomalias cardíacas foram shunt da esquerda para a direita (n = 47) e obstrução da via de saída do ventrículo direito (n = 14). Destes, 26 apresentaram comunicação interventricular, 15 comunicação interauricular e sete pacientes apresentaram tetralogia de Fallot. Cinco pacientes apresentaram disritmias. CONCLUSÕES: Devido à elevada prevalência de anomalias cardíacas na população de doentes com Fenda Lábio-Palatina, aconselhamos uma avaliação cardíaca de rotina em todos.

Burden of schistosomiasis-related mortality in Brazil: epidemiological patterns and spatial-temporal distribution, 2003-2018.

OBJECTIVE: To characterise the epidemiological patterns and the spatial-temporal distribution of schistosomiasis-related mortality in Brazil from 2003 to 2018. METHODS: A national population-based ecological study that used official data from the Mortality Information System. The data included all deaths recorded in Brazil from 2003 to 2018 in which schistosomiasis was mentioned in the death certificate as an underlying or associated cause of death (multiple causes). The municipalities of residence were used as units of geographic analysis, and standardised and smoothed mortality rates (per 100 000 inhabitants) were calculated using the local empirical Bayes method. Spatial autocorrelation was evaluated using global and local Moran indexes. To analyse the spatial dependence, the Getis-Ord G and Gi* statistics were used. RESULTS: During the study period, 18 421 113 deaths were recorded in Brazil. Schistosomiasis was mentioned in 11 487 deaths (proportional mortality: 0.06%); for 8141 deaths (70.87%), it was listed as the underlying cause, and for 3346 deaths (29.13%), it was listed as an associated cause. The mean mortality rate was 0.38 deaths/100 000 inhabitants. Individuals ≥ 70 years of age (RR: 115.34, 95% CI: 68.56-194.03) and residents in the Northeast region (RR: 10.81, 95% CI: 5.95-19.66) presented higher risks related to schistosomiasis. Municipalities with high mortality rates were identified in all regions, and high-risk clusters were found in municipalities located in the Northeast and Southeast regions of the country. CONCLUSIONS: Schistosomiasis remains an important cause of death in persistently endemic areas in Brazil, particularly in those with a high prevalence of the disease and a marked parasite load.

OBJECTIF: Caractériser les profils épidémiologiques et la distribution spatio-temporelle de la mortalité liée à la schistosomiase au Brésil de 2003 à 2018. MÉTHODES: Une étude écologique nationale basée sur la population qui a utilisé les données officielles du système d'information sur la mortalité. Les données incluaient tous les décès enregistrés au Brésil de 2003 à 2018 dans lesquels la schistosomiase était mentionnée dans le certificat de décès comme cause sous-jacente ou associée (causes multiples) de décès. Les municipalités de résidence ont été utilisées comme unités d'analyse géographique et les taux de mortalité normalisés et lissés (pour 100.000 habitants) ont été calculés à l'aide de la méthode empirique locale de Bayes. L'autocorrélation spatiale a été évaluée à l'aide d'indices de Moran globaux et locaux. Pour analyser la dépendance spatiale, les statistiques de Getis-Ord G et Gi* ont été utilisées. RÉSULTATS: Au cours de la période d'étude, 18.421.113 décès ont été enregistrés au Brésil. La schistosomiase a été mentionnée dans 11.487 décès (mortalité proportionnelle: 0,06%); pour 8.141 décès (70,87%), elle a été répertoriée comme la cause sous-jacente et pour 3.346 décès (29,13%), comme cause associée. Le taux de mortalité moyen était de 0,38 décès/100.000 habitants. Les personnes âgées de ≥70 ans (RR: 115,34 ; IC95%: 68,56 à 194,03) et les résidents de la région du Nord-Est (RR: 10,81 ; IC95%: 5,95 à 19,66) présentaient des risques plus élevés liés à la schistosomiase. Des municipalités présentant des taux de mortalité élevés ont été identifiées dans toutes les régions et des grappes à haut risque ont été trouvées dans des municipalités situées dans les régions du nord-est et du sud-est du pays. CONCLUSIONS: La schistosomiase reste une cause importante de mortalité dans les zones d'endémie persistante du Brésil, en particulier dans celles à forte prévalence de la maladie et à forte charge parasitaire.

Relevancia de los arrays de hibridación genómica comparada en el estudio de los retrasos del desarrollo en pediatría / Array-CGH: importance in the study of developmental delays in pediatrics

INTRODUCCIÓN: El retraso general del desarrollo (RGD) constituye un trastorno intelectual y del comportamiento adaptativo que aparece en los niños menores de 5 años que no consiguen alcanzar los hitos del desarrollo normal. La discapacidad intelectual se caracteriza por la limitación en el funcionamiento intelectual y en el comportamiento adaptativo, surgida en la infancia. Entre las causas frecuentes y reconocibles del RGD y de la discapacidad intelectual se encuentran los desequilibrios cromosómicos. Los arrays de hibridación genómica comparada (aCGH) han contribuido a mejorar la tasa de detección de las anomalías genéticas y ya se consideran la prueba genética de elección para la discapacidad intelectual de origen desconocido. OBJETIVO: Analizar los resultados del estudio genético con aCGH motivado por un RGD o una discapacidad intelectual en pacientes pediátricos. PACIENTES Y MÉTODOS: Análisis retrospectivo de pacientes pediátricos sometidos a seguimiento ambulatorio que fueron objeto de un estudio genético con aCGH entre 2012 y 2017. RESULTADOS: El número de pacientes sometidos al estudio con aCGH ascendió a 215. Del total, el 64,2% fueron investigados por discapacidad intelectual, y el 35,8%, por RGD. El 23,3% presentó deleciones o duplicaciones en la aCGH; el 56%, por la discapacidad intelectual; y el 44%, por el RGD, y los cromosomas 16, 22, 2 y 1 fueron los implicados con más frecuencia. CONCLUSIÓN: El presente estudio demuestra la mayor prevalencia de ambos en el sexo masculino, en consonancia con otras publicaciones precedentes. La tasa de detección de las anomalías clasificadas como patógenas resultó superior a la notificada en otros estudios

INTRODUCTION: Global developmental delay (GDD) is an intellectual and adaptive impairment in infants under 5 years of age who fail to meet expected developmental milestones. Intellectual disability is characterized by limitation in intellectual function and adaptive behavior, with onset in childhood. Frequent identifiable causes of GDD and intellectual disability are chromosomal imbalances. The array comparative genomic hybridization (aCGH) has contributed to improve the detection rate of genetic abnormalities and is considered the first-tier genetic test for unexplained intellectual disability. AIM: To analyze the results of a genetic study by aCGH due to GDD or intellectual disability in pediatric patients. PATIENTS AND METHODS: Retrospective analysis of pediatric patients followed in outpatient, which underwent a genetic study by aCGH, from 2012 to 2017. RESULTS: 215 patients were studied by aCGH. Of the total, 64.2% were investigated for intellectual disability and 35.8% for GDD. A 23.3% presented aCGH deletions or duplications, 56% for intellectual disability and 44% for GDD, with chromosomes 16, 22, 2 and 1 being the most implicated. CONCLUSION: Our study demonstrated a higher prevalence in males, according to previously published reports. The rate of detection abnormalities classified as pathogenic was higher than in other studies
