Endometrial cancer treatment and outcomes in Argentina: ECHOS-A real-world study.

Objective: Real-world data for patients with endometrial cancer (EC) are limited, particularly in Latin America. We present treatment pattern findings from ECHOS-A - Endometrial Cancer Health Outcomes Study in Argentina. Materials and methods: A retrospective study using clinical data from privately insured patients with EC diagnosed from 2010 to 2019. Index (diagnosis proxy) was first date of an EC-related health term or treatment. Demographics, clinical characteristics, and FIGO staging were described. Disease progression and survival were assessed until study end, loss to follow-up, or death. Results: Of 805 patients with EC, 77.4 % (n = 623/805) received any treatment and 22.6 % (n = 182/805) received none. Among those treated, 31.8 % (n = 198/623) had first-line (1L) systemic therapy, and 45.5 % (n = 90/198) proceeded to second-line (2L) therapy. Mean follow-up was 33.6 (SD 31.8) months. Of those receiving any treatment, 87.3 % (n = 544/623) had FIGO stage data (I, 62.9 %; II, 18.6 %; III, 13.6 %; IV, 5.0 %). Treatment by class in 1L and 2L, respectively, were platinum chemotherapy, 73.7 %, 36.7 %; non-platinum chemotherapy, 73.7 %, 62.2 %; immunotherapy, 1.0 %, 11.1 %; hormone therapy, 17.7 %, 26.7 %. Carboplatin/paclitaxel was the most frequent 1L (52.5 %) and 2L (14.4 %) regimen. Mean time to progression was 14.1 (SD 16.3) and 8.8 (SD 8.3) months in 1L and 2L, respectively. Adjusted 1- to 5-year risk of progression/death was 46.5-77.5 % and 65.0-86.2 % in 1L and 2L, respectively. Conclusions: Approximately one-quarter of patients with EC received no treatment, and approximately two-thirds were not treated with 1L systemic therapy. Efforts to better understand the reasons for these treatment patterns are crucial for improving patient outcomes.

OCEANIA: real-world study of ovarian cancer treatment patterns across multiple lines of therapy in Argentina and Brazil.

Aim: To evaluate real-world data on treatment patterns in Argentina and Brazil in patients with ovarian cancer. Methods: This study evaluated de-identified antineoplastic exposure data from a private healthcare provider in Argentina and health claims database (Orizon) in Brazil from 2010 to 2019 and 2015 to 2020, respectively. Results: Platinum-based chemotherapy was the most common first-line therapy (Argentina: n =311 [87.6%]; Brazil: n = 1142 [79.3%]). The proportion of patients receiving platinum-based chemotherapy declined across both populations from first- to second-line, while use of non-platinum-based, targeted, and hormone therapies increased. Duration of platinum-based treatment and time to next treatment decreased from first- to fourth-line. Conclusion: There is an unmet need for effective therapies that can prolong time to next treatment in ovarian cancer in Argentina and Brazil.

Influence of hydroxyurea on tubular phosphate handling in sickle cell nephropathy.

OBJECTIVE: This study aims to evaluate the markers of tubular phosphate handling in adults with sickle cell anemia (SCA) and the influence of hydroxyurea (HU), the degree of anemia and Hb F concentration on these markers. METHODS: Eighty-eight steady state SCA patients in outpatient follow-up in Fortaleza, Ceara, Brazil and 31 healthy individuals were included in this study. Vitamin D (25OHD) was measured by enzyme-bound fluorescence assay, intact parathyroid hormone (iPTH) by electrochemiluminescence, and serum and urinary phosphate and creatinine by colorimetric methods. Details of Hb F and HU use were obtained from clinical records. Tubular reabsorption of phosphate (TRP) and maximum tubular reabsorption of phosphate (MTRP) were calculated. SCA patients were stratified according to the use of HU, degree of anemia and percentage of Hb F. The significance level was set for p-values <0.05. RESULTS: Compared to controls the 25OHD level (25 ± 11 vs. 30 ± 9 pg/mL) was lower in SCA, while serum phosphate and MTRP were higher (3.86 ± 0.94 vs. 3.46 ± 0.72 and 3.6 ± 1.21 vs. 3.21 ± 0.53, respectively). There was no significant difference in iPTH, TRP and phosphaturia. Serum phosphate showed correlation with TRP (r = 0.32; p-value = 0.008) and MTRP (r = 0.9; p-value <0.001) in SCA. Patients taking HU, especially those with Hb F >10 % presented reduced serum phosphate levels, and TRP and MTRP rates. Those with mild anemia presented reduced serum phosphate levels and MTRP rates. CONCLUSION: Serum phosphate levels and renal phosphate reabsorption rate were increased in SCA. HU use, high Hb F concentration and total Hb were associated with better control of tubular phosphate handling markers.

Nocardiosis: a single-center experience and literature review.

INTRODUCTION: Nocardiosis is a rare bacterial infection caused by Nocardia spp. However, an increasing incidence has been described whereby data about epidemiology and prognosis are essential. METHODS: A retrospective descriptive study was conducted among patients with positive Nocardia spp. culture, from January 2019 to January 2023, at a Terciary Hospital in Portugal. RESULTS: Nocardiosis was considered in 18 cases with a median age of 63.8-years-old. At least one immunosuppressive cause was identified in 70% of patients. Five patients had Disseminated Nocardiosis (DN). The lung was the most common site of clinical disease (77.8%) and Nocardia was most commonly identified in respiratory tract samples. The most frequently isolated species were Nocardia nova/africana (n = 7) followed by Nocardia cyriacigeorgica (n = 3) and Nocardia pseudobrasiliensis (n = 3). The majority of the patients (94.4%) received antibiotic therapy, of whom as many as 55.6% were treated with monotherapy. The most frequently prescribed antibiotic was trimethoprim-sulfamethoxazole. Selected antimicrobial agents were generally effective, with linezolid and cotrimoxazole (100% Susceptibility [S]) and amikacin (94% S) having the most activity against Nocardia species. The median (IQR) duration of treatment was 24.2 (1‒51.4) weeks for DN; The overall one-year case fatality was 33.3% (n = 6) and was higher in the DN (66.7%). No recurrence was observed. CONCLUSION: Nocardiosis is an emerging infectious disease with a poor prognosis, particularly in DN. This review offers essential epidemiological insights and underscores the importance of gaining a better understanding of the microbiology of nocardiosis. Such knowledge can lead to the optimization of antimicrobial therapy and, when necessary, guide appropriate surgical interventions to prevent unfavorable outcomes.

Dominican Adolescents' Preferences for Content, Design, and Functionality of a Mobile Application for Type 1 Diabetes Mellitus Self-management.

OBJECTIVE: The purpose of this interdisciplinary study was to determine Dominican adolescents' preferences for the content, functionality (i.e. food's glycemic index list, and amount of insulin based on foods' carbohydrate count), and design of a culturally and linguistically relevant mobile application (app) for type 1 diabetes mellitus (T1DM) self-management. The app would facilitate T1DM self-management education and support by addressing providers' challenges in monitoring patients' disease progression and promoting patient adherence to recommended lifestyle changes. Findings inform an app development process that considers the linguistic and cultural values, norms, and structures of people with T1DM and their providers in the Dominican Republic. METHODS: Phone interviews were conducted with 23 adolescents (14 to 18 years of age), using a semistructured questionnaire. The research team conducted the data analysis using NVivo through a deductive and inductive approach. RESULTS: The findings suggest that, regardless of the context, adolescents with T1DM desire similar features and functionalities in a self-management app. Overall, participants preferred an app with a graphic format that has accessible information, a straightforward design, and instructional videos. Participants also desired that an app provide information and reminders about proper eating and insulin administration timing and be a vehicle to access a social network to foster mutual support and encouragement. CONCLUSIONS: Our study highlights adolescents' perspectives on components for inclusion in an app for T1DM self-management. Participants' recommendations for the app's potential usability, contents, and design features will be used to guide the development of a new app to promote engagement and foster better health outcomes.

Invasive and Subcutaneous Infections Caused by Filamentous Fungi: Report from a Portuguese Multicentric Surveillance Program.

Invasive fungal infections (IFI) have significantly increased over the past years due to advances in medical care for the at-risk immunocompromised population. IFI are often difficult to diagnose and manage, and can be associated with substantial morbidity and mortality. This study aims to contribute to understanding the etiology of invasive and subcutaneous fungal infections, their associated risk factors, and to perceive the outcome of patients who developed invasive disease, raising awareness of these infections at a local level but also in a global context. A laboratory surveillance approach was conducted over a seven-year period and included: (i) cases of invasive and subcutaneous fungal infections caused by filamentous/dimorphic fungi, confirmed by either microscopy or positive culture from sterile samples, (ii) cases diagnosed as probable IFI according to the criteria established by EORTC/MSG when duly substantiated. Fourteen Portuguese laboratories were enrolled. Cases included in this study were classified according to the new consensus definitions of invasive fungal diseases (IFD) published in 2020 as follows: proven IFI (N = 31), subcutaneous fungal infection (N = 23). Those proven deep fungal infections (N = 54) totalized 71.1% of the total cases, whereas 28.9% were classified as probable IFI (N = 22). It was possible to identify the etiological fungal agent in 73 cases (96%). Aspergillus was the most frequent genera detected, but endemic dimorphic fungi represented 14.47% (N = 11) of the total cases. Despite the small number of cases, a high diversity of species were involved in deep fungal infections. This fact has implications for clinical and laboratory diagnosis, and on the therapeutic management of these infections, since different species, even within the same genus, can present diverse patterns of susceptibility to antifungals.

Presence of Human Papillomavirus in Human Tissues and the Environment.

Human Papillomavirus is one of the most well-known pathogens having potential to cause both benign and malignant illnesses. The current controversy focuses on its continuity in non-epithelial tissues and the environment, and its ability to cause infection in these settings. This review addresses the virology aspects that contribute to its presence and resistance in humans and the environment.

Off-label drug use in an adult intensive care unit of a Brazilian hospital

Abstract The objective of this study was to determine the prevalence and describe the factors associated with off-label drug use in an adult intensive care unit (ICU) of a Brazilian hospital. An analytical, cross-sectional, prospective study was conducted in the adult ICU population from March 2018 to May 2018. Off-label use of medication was classified by indication, dosage, route of administration, type and volume of diluent, and duration of administration. Most patients were female (57.89%), non-elderly (56.14%), and had a mean age of 54.44 ± 17.15 years. The prevalence of off-label drug use was 70.31%, but was not associated with the clinical severity of the patients. A statistically significant association was observed between label use of drugs and prescribing potentially inappropriate medicines (PIM). The most common reasons for off-label drug use were therapeutic indication (19.58%) and volume of diluent (23.30%). Drug administration by enteral tubes accounted for the largest number of off-label uses due to route of administration (90.85%). There was a higher prevalence of off-label use of systemic antimicrobials (14.44%) and norepinephrine (9.28%). Our study provided a broad characterization of off-label drug use in an adult ICU and showed why it is important for health professionals to evaluate the specific risks and benefits of this practice

Association between asthma and sleep hours in Brazilian adolescents: ERICA

Abstract Objective To investigate the association between asthma and sleep duration in participants of the Study of Cardiovascular Risks in Adolescents. Materials and methods Cross-sectional, national, school-based study, involving adolescents aged 12-17 years. In the period between 2013−14, data from 59,442 participants were analyzed. Bivariate analysis between current asthma and short sleep duration, defined as < 7 h/night, was performed separately with the other variables analyzed: sex, age group, type of school, weight categories, and common mental disorders. Then, different generalized linear models with Poisson family and logarithmic link functions were used to assess the independence of potential confounding covariates associated with both asthma and short sleep duration in the previous analysis. Crude and adjusted prevalence ratios and respective 95% confidence intervals were calculated, and a value of p < 0.05 was considered significant for all analyses performed. Results Prevalence of current asthma was 13.4%, being significantly higher among students with short sleep duration (PR: 1.17; 95% CI: 1.01-1.35; p = 0.034). This remained significant even after adjusting for the other study covariates. Conclusion There was a positive association between the prevalence of current asthma and short sleep duration among Brazilian adolescents. Considering the high prevalence and morbidity of the disease in this age group, the promotion of sleep hygiene should be considered as a possible health strategy aimed at contributing to better control of asthma in this population.

Septic Shock Due to Capnocytophaga canimorsus Infection in a Splenectomized Patient.

Capnocytophaga canimorsus is a gram-negative rod that is part of the commensal flora of dogs' mouths. Among splenectomized patients who maintain close contact with dogs, the bacteria can lead to infection and fulminant sepsis even without evidence of a skin breach. In this report, we describe the case of a 71-year-old woman who had undergone splenectomy 35 years ago. She came to our emergency department complaining of back pain, myalgia, asthenia, and a fever of 40.2ºC. No other symptoms were noted upon her admission. Blood workup revealed hyperlacticaemia, increased C-reactive protein, and lymphopenia. A urinalysis and chest radiography were ordered, with no abnormal findings, and the SARS-CoV-2 test was negative. The patient developed persistent hypotension and drowsiness that did not improve with intravenous fluids. Therefore, she was started on a norepinephrine infusion. Cultures were collected, and intravenous antibiotic therapy was started with amoxicillin/clavulanic acid 2.2 mg and azithromycin 500 mg. Besides all the diagnostic tests, no infectious cause was found. On the second day of hospitalization, she started to deteriorate, and antibiotic therapy was escalated to piperacillin/tazobactam 4.5 g, resulting in a good clinical response. On the third day after admission, thanks to a group discussion, we were able to identify C. canimorsus in the patient's blood cultures. A review of history revealed that the patient was in close contact with her pet dog. This case highlights the importance of a multidisciplinary discussion, including the microbiology team, in order to reach an uncommon diagnosis. When dealing with splenectomized individuals presenting with the septic shock of unclear origin, a history of close contact with dogs must lead clinicians to consider C. canimorsus as a causative agent.

Severe asthma and eligibility for biologics in a Brazilian cohort.

OBJECTIVE: This study aims to describe the eligibility for biologic therapies for severe asthma (SA) in a cohort of patients attending the Program for Control of Asthma (ProAR) in Bahia, Brazil. METHODS: Data from SA patients (≥18 years old) attending the ProAR, that were included in a case-control study conducted from 2013 to 2015, were used to reassess patients according to a modified ERS/ATS 2014 SA criteria. Patients were then classified according to the eligibility for SA biological therapy based on current prescription labels. RESULTS: From 544 patients in the cohort, 531 (97.6%) were included and 172 (32.4%) were identified as SA patients according to the ERS/ATS 2014 modified criteria. Of these 172 patients, 69 (40.1%) were ineligible for any of the biologicals approved for asthma (omalizumab, mepolizumab, reslizumab and benralizumab), 60 (34.9%) patients were eligible for one of the biological therapies, and 10 (5.8%) patients were eligible for all biological therapies. CONCLUSIONS: More than half of patients with SA were eligible for biologic therapy in our study, but none of them received this form of treatment. Almost half of them were not eligible to any of the approved biologics, however. The variability and overlap in patients' eligibility highlight the importance of evaluating each patient individually for a more personalized treatment approach. While there is a need to increase access for some of those eligible that may really need a biologic treatment, continuous efforts are required to develop alternatives to those who are not eligible.

Multiplicity of Carbapenemase-Producers Three Years after a KPC-3-Producing K. pneumoniae ST147-K64 Hospital Outbreak.

Carbapenem resistance rates increased exponentially between 2014 and 2017 in Portugal (~80%), especially in Klebsiella pneumoniae. We characterized the population of carbapanemase-producing Enterobacterales (CPE) infecting or colonizing hospitalized patients (2017-2018) in a central hospital from northern Portugal, where KPC-3-producing K. pneumoniae capsular type K64 has caused an initial outbreak. We gathered phenotypic (susceptibility data), molecular (population structure, carbapenemase, capsular type) and biochemical (FT-IR) data, together with patients' clinical and epidemiological information. A high diversity of Enterobacterales species, clones (including E. coli ST131) and carbapenemases (mainly KPC-3 but also OXA-48 and VIM) was identified three years after the onset of carbapenemases spread in the hospital studied. ST147-K64 K. pneumoniae, the initial outbreak clone, is still predominant though other high-risk clones have emerged (e.g., ST307, ST392, ST22), some of them with pandrug resistance profiles. Rectal carriage, previous hospitalization or antibiotherapy were presumptively identified as risk factors for subsequent infection. In addition, our previously described Fourier Transform infrared (FT-IR) spectroscopy method typed 94% of K. pneumoniae isolates with high accuracy (98%), and allowed to identify previously circulating clones. This work highlights an increasing diversity of CPE infecting or colonizing patients in Portugal, despite the infection control measures applied, and the need to improve the accuracy and speed of bacterial strain typing, a goal that can be met by simple and cost-effective FT-IR based typing.

Prevalence of Combined Lipid Abnormalities in Brazilian Adolescents and Its Association with Nutritional Status: Data from the Erica Study.

Background: Cardiovascular diseases are the leading cause of death in Brazil and worldwide. The growing incidence of obesity in children and adolescents and its association with lipid abnormalities may worsen this scenario, mainly in developing countries where obesity has reached epidemic levels. Dyslipidemias have several patterns, and the combination of some lipid abnormalities may have higher atherogenic potential. Objectives: To evaluate the prevalence of single or multiple combined lipid abnormalities in adolescents and its association with nutritional status assessed by body mass index. Methods: Data were obtained from the Study of Cardiovascular Risks in Adolescents (ERICA), a school-based, national representative study with Brazilian adolescents between 12 and 17 years of age. Adolescents whose lipid profiles were available were included, and lipid abnormalities were defined as LDL-C ≥ 100 mg/dL, HDL-C < 45 mg/dL, and tryglicerides (TG) ≥ 100 mg/dL. We assessed the prevalence of single or combined lipid abnormalities and correlated this nutritional status with body mass index of low weight, normal, overweight, and obesity. Results: A total of 38,069 adolescents were included, with more than 24,000 of them presenting at least one lipid abnormality (64.7%), and 3.7% showing alterations in all of them. The most prevalent combination was high TG with low HDL-C levels. The higher the BMI, the more lipid abnormalities were found. Conclusions: In this large and representative sample of Brazilian adolescents, the majority had at least one lipid abnormality. Higher BMI was associated with a higher prevalence of combined lipid abnormalities. Highlights: - There is a high prevalence of Brazilian adolescents with dyslipidemias.- BMI was associated with a higher prevalence of combined lipid abnormalities.- BMI can be considered as an indicator of the diagnosis of dyslipidemia in adolescents.

Association Between Abdominal Waist Circumference and Blood Pressure In Brazilian Adolescents With Normal Body Mass Index: Waist circumference and blood pressure in Adolescents.

Obesity is the most common chronic disease in adolescents. In adults, waist circumference (WC) is associated with the presence of cardiovascular risk factors and is also a better predictor of cardiovascular (CV) risk than body mass index (BMI). The association between WC and CV risk factors in adolescents has been poorly explored so far, mainly in those within the normal BMI range. Objective: To evaluate the association between WC and elevated blood pressure (BP) in adolescents with a normal BMI. Methods: Cross-sectional analysis of 73,399 scholars between 12 and 17 years old from the ERICA study, a school-based, national representative study with Brazilian adolescents. Only those within the normal range of BMI were included. The WC was categorized into quartiles for sex and age (Q1 to Q4). For the analysis, BP values ≥ 90th percentile were considered to indicate elevated BP, what includes hypertension and pre-hypertension. The Poisson Regression model was used and the prevalence ratio was estimated. Results: A total of 53,308 adolescents with normal BMI were included. Prevalence of elevated BP in the overall group was 18.0%. In female adolescents with WC in the lowest quartile for their age, the prevalence of elevated BP was 7.3% (12-14 years) and 6.9% (15-17 years), increasing in the upper quartile to 15.2% and 19.5% respectively, with a prevalence ratio (PR) indicating chance at least two times higher for elevated BP in Q4 (p < 0.001). Similarly, this was observed in boys, with a prevalence of elevated BP of 10.0% and 18.9% in Q1, increasing to 21.4% and 49.6% in Q4 (p < 0.001). Conclusion: In adolescents, there is a strong association of increased WC with BP elevation, even when the BMI is adequate.

Quality of life and its relation with nutritional status in patients with incurable cancer in palliative care.

BACKGROUND: Nutritional impairment is common in cancer patients and adversely affects quality of life (QoL). The aim of this study was to investigate the association between nutritional status and QoL in incurable cancer patients in palliative care. METHODS: A prospective cohort with incurable cancer patients referred to the specialized Palliative Care Unit of the National Cancer Institute in Brazil was conducted. The nutritional risk (NR) was assessed using the Patient-Generated Subjective Global Assessment short form (PG-SGA SF), and cancer cachexia (CC) was defined according to the international consensus. QoL was evaluated using the Quality of Life Questionnaire Core 15 Palliative (QLQ-C15-PAL). Multivariate linear regressions analyses were performed to assess the relationship between the nutritional status and QoL scores. RESULTS: A total of 1039 consecutive patients were included. A high prevalence of NR (85.4%) and CC (78.7%) were observed. The patients with worse nutritional status presented significantly poorer physical, emotional, symptoms domains scales, and overall QoL. CC were significantly associated with QoL scores for dyspnea (p = 0.013), insomnia (p = 0.046), and appetite loss (p = 0.015), while NR were associated with all the QoL domains scales covered in QLQ-C15-PAL. CONCLUSION: Our findings support that impaired nutritional status was associated with poor QoL in incurable cancer patients. NR assessed by PG-SGA SF better reflects physical, emotional, symptom burden, and overall QoL scores. Thus, this tool may contribute in identifying patients at risk of deterioration QoL.

[Quality analysis of self-reported information on sleep duration in schoolchildren in the Study of Cardiovascular Risk Factors in Adolescents (ERICA)]. / Análise da qualidade da informação autorreferida sobre duração do sono de escolares do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA).

The study aimed to assess sleep behavior in adolescents 12 to 17 years of age participating in ERICA (Study of Cardiovascular Risk Factors in Adolescents), based on sociodemographic characteristics, school shift, and type of school, and to describe the correction of inconsistent sleep times in a nationally representative study in Brazil. Data were collected in 2013 and 2014. Four questions were asked on habitual time for sleeping and waking on weekdays and weekends, with 24 possible answers, one for each hour of the day. Analysis of inconsistencies considered the distribution of frequencies of answers as to sleeping and waking times, in addition to compatibility with the school shift. Sleep duration during the week and on weekends was obtained by the difference between sleeping and waking times, and differences of ≤ 4 or ≥ 14 hours were excluded. Mean total sleep duration in seven days was calculated by the formula (weekday sleep duration x 5 + weekend sleep duration x 2)/7. The following groups were created: original data (answers that did not require correction), corrected data (inconsistent, but amenable to correction), and excluded data (inconsistent, and for which there was no criterion for correction). Correction recovered inconsistent information for 5,988 adolescents, 8% of the 74,589 participants. A total of 7,937 (10.6%) answers were excluded. Adolescents whose information was corrected or excluded were younger, predominantly males, from public schools, and from the North of Brazil. Correction minimized losses and lent greater consistency to the data treatment. The study contributes to the improvement of data collection tools in observational studies, lending transparency to the way of dealing with inherent limitations in the data collection method.

Objetivou-se avaliar o comportamento do sono de adolescentes de 12 a 17 anos, participantes do ERICA (Estudo de Riscos Cardiovasculares em Adolescentes), estudo de representatividade nacional, segundo características sociodemográficas, turno e tipo de escola, e descrever a correção das horas inconsistentes. A coleta de dados ocorreu em 2013 e 2014. Foram feitas quatro perguntas sobre horas habituais de dormir e de acordar durante a semana e no final de semana, com 24 opções de respostas, uma para cada hora do dia. A análise das inconsistências considerou a distribuição de frequências das respostas quanto às horas habituais de dormir e de acordar, além da compatibilidade com o turno. A duração do sono durante a semana e final de semana foi obtida pela diferença entre horas habituais de dormir e de acordar e foi excluída se ≤ 4 ou ≥ 14 horas. A média de sono total da semana foi calculada pela fórmula: (duração do sono durante a semana x 5 + duração do sono no final de semana x 2)/7. Foram criados três grupos: dados originais (respostas que não necessitaram correções), dados corrigidos (inconsistentes, mas passíveis de correção) e dados excluídos (inconsistentes, para os quais não se tinha critério para correção). A correção recuperou informação inconsistente de 5.988 adolescentes (8%) dos 74.589 participantes. Foram excluídas 7.937 (10,6%) respostas. Os adolescentes cujas informações foram corrigidas ou excluídas são mais novos, do sexo masculino, de escolas públicas e da Região Norte. A correção minimizou perdas e conferiu maior consistência ao tratamento dos dados. O estudo contribui para o aprimoramento da construção de instrumentos de coleta de dados em estudos observacionais, tornando transparente a forma de lidar com as limitações inerentes ao método de coleta de dados.

El objetivo fue evaluar el comportamiento del sueño en adolescentes de 12 a 17 años, participantes en el ERICA (Estudio de Riesgos Cardiovasculares en Adolescentes), según características sociodemográficas, turnos y tipos de escuela, donde además se describe la corrección de las horas incompatibles en un estudio de nivel nacional en Brasil. La recogida de datos se realizó en 2013 y 2014. Se hicieron cuatro preguntas sobre las horas habituales de sueño y de despertarse durante la semana y el fin de semana, con 24 opciones de respuesta, una para cada hora del día. El análisis de las incompatibilidades consideró la distribución de frecuencias en las respuestas, respecto a las horas habituales de sueño y de despertarse, además de la compatibilidad con el turno. La duración del sueño durante la semana y fin de semana se obtuvo mediante la diferencia entre horas habituales de sueño y de despertarse y fue excluida si ≤ 4 ó ≥ 14 horas. La media de sueño total de la semana se calculó mediante la fórmula: (duración del sueño durante la semana x 5 + duración del sueño durante el fin de semana x 2)/7. Se crearon tres grupos: datos originales (respuestas que no necesitaron correcciones), datos corregidos (inconsistentes, pero plausibles de corrección) y datos excluidos (inconsistentes en los que no había criterio para la corrección). La corrección recuperó información inconsistente de 5.988 adolescentes (8%) de los 74.589 participantes. Se excluyeron 7.937 (10,6%) respuestas. Los adolescentes cuya información fue corregida o excluida son más jóvenes, sexo masculino, procedentes de escuelas públicas y de la región Norte. La corrección minimizó pérdidas y otorgó una mayor consistencia al tratamiento de los datos. El estudio contribuye al perfeccionamiento de la creación de instrumentos de recogida de datos en estudios observacionales, haciendo transparente la forma de enfrentarse a las limitaciones inherentes del método de recogida de datos.
