Children and adolescents with sickle cell disease: characteristics and use of medicinal plants / Crianças e adolescentes com doença falciforme: características e uso de plantas medicinais

ABSTRACT Objective: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. Methods: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. Results: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). Conclusions: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

RESUMO Objetivo: Descrever as características epidemiológicas de pacientes pediátricos com doença falciforme (DF) e avaliar o uso de plantas medicinais concomitantemente ao tratamento medicamentoso. Métodos: Realizou-se revisão de prontuários de pacientes pediátricos de uma instituição pública com nível de atendimento terciário; o critério de seleção foi ser criança ou adolescente com DF em acompanhamento pediátrico neste ambulatório. Nos prontuários dos pacientes selecionados foi procurado o registro do uso de plantas com finalidades medicinais. Resultados: Foram revisados 154 prontuários (100% dos pacientes ativos desse ambulatório): 99 crianças e 55 adolescentes. O genótipo predominante foi SS (58,4%), seguido do SC (29,2%). O uso de ao menos uma medicação para a DF foi relatada em 95,5% dos prontuários. Em 70,1% dos prontuários havia o relato do uso de plantas medicinais, em 276 citações, sendo 64 plantas citadas ao todo; destas, seis espécies foram citadas para o tratamento da doença de base (DF), sendo "ora-pro-nobis" (Pereskia aculeata) a principal. Das 276 citações de plantas medicinais nos prontuários, 60,5% incluíram o uso de plantas medicinais em sintomas gripais e/ou COVID-19 (tanto prevenção quanto tratamento), sendo relatadas 35 para este uso, exclusivamente ou não. Essa foi a principal finalidade de uso encontrada nos prontuários dos pacientes, seguida do uso para sintomas de dor (14,2% das citações). Conclusões: Notou-se que a maioria dos pacientes avaliados faz uso da medicina convencional, aliada à tradicional/ complementar/ alternativa, o que leva à necessidade de mais estudos nessas áreas, especialmente na pediatria, visando principalmente à segurança do paciente.

Prevalence of myopic eyes in private practice and public care services in Brazil: 11 years of retrospective analysis

ABSTRACT Purpose: This study aimed to examine the prevalence of myopic eyes over 11 years (2008-2018) in a private clinic and a public assistance service. Methods: We retrospectively evaluated 6332 individuals (12,664 eyes) between 5 and 25 years old, seen at a private clinic-CEMO (2,663 individuals) and a public service-HOIP (3,669 individuals) from 2008 to 2018. We evaluated the prevalence of myopic eyes (EE ≤-0.50) and high myopic eyes (EE ≤-6.00). Results: Sex and services did not show statistical differences. The variation in the prevalence of myopic and high myopic eyes showed a random pattern during the study period (this prevalence could not be increased). Prevalences ranged from 20.7% (in 2017) to 32.4% (in 2015) for myopic eyes and from 1.6% (in 2009 and 2016) to 3.3% (in 2015) for eyes with high myopia. The prevalence of myopia showed a statistically significant increase based on the age group. Conclusion: The prevalence of myopic eyes did not increase in our study. The mean prevalence of myopic eyes was similar in the private clinic and public service.

Seasonality of the incidence of bronchiolitis in infants — Brazil, 2016-2022: An interrupted time-series analysis / Sazonalidade da incidência de bronquiolite em lactentes — Brasil, 2016-2022: Uma análise de série temporal interrompida

ABSTRACT Objective: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020-2022 season and compare it with the previous seasons. Methods: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Results: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 - August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 - December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020-2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. Conclusions: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

RESUMO Objetivo: Avaliar a sazonalidade da bronquiolite aguda no Brasil durante a temporada 2020-2022 e compará-la com a das temporadas anteriores. Métodos: Os dados de incidência de internações por bronquiolite aguda em lactentes <1 ano de idade foram obtidos do Departamento de Informática da base de dados da Saúde Pública Brasileira para o período entre 2016 e 2022. Esses dados também foram analisados por macrorregiões do Brasil (Norte, Nordeste, Sudeste, Sul e Centro-Oeste). Para descrever características sazonais e de tendência ao longo do tempo, utilizamos o Modelo de Médias Móveis Integradas Autorregressivas Sazonais. Resultados: Em comparação com o período pré-COVID-19, a incidência de hospitalizações relacionadas com bronquiolite aguda diminuiu 97% durante as intervenções não farmacológicas (março de 2020 - agosto de 2021), mas aumentou 95% após a flexibilização das intervenções não farmacológicas (setembro de 2021 - dezembro de 2022), resultando no aumento geral de 16%. Durante o período pré-COVID-19, as hospitalizações por bronquiolite aguda seguiram um padrão sazonal, que foi interrompido em 2020-2021, mas recuperaram-se em 2022, com um pico ocorrido em maio, aproximadamente 4% superior ao pico pré-COVID-19. Conclusões: Este estudo ressalta a influência significativa das intervenções contra a COVID-19 nas hospitalizações por bronquiolite aguda no Brasil. A restauração de um padrão sazonal em 2022 sublinha a interação entre as medidas de saúde pública e a dinâmica das doenças respiratórias em crianças pequenas.

Feedback received and role performance: The mediating role of engagement and the moderating role of authentic living

This research aims to identify the moderating role of authentic living in the relationship between feedback received and role performance, mediated by work engagement. The data were based on a convenience sample of Brazilian workers from public and private organizations (N = 1,244). The significant interaction between the feedback and authentic living allowed us to understand that the main effects of feedback on performance take place in individuals with high authentic living. When individuals are more authentic, the information they receive about their performance more strongly affects the motivational process at work itself. This study highlights the positive relationship between work and personal resources, as well as the work engagement and performance on the other, thus contributing to increase the feedback the organizations receive about performance, as well as to create environments that facilitate authenticity.

O objetivo desta pesquisa foi identificar o papel moderador da vivência autêntica na relação do feedback recebido com o desempenho de papéis, mediado pelo engajamento no trabalho. Os dados foram obtidos a partir de uma amostra por conveniência de trabalhadores brasileiros provenientes de organizações públicas e privadas (N = 1.244). A interação significativa entre o feedback e a vivência autêntica permitiu compreender que os maiores efeitos do feedback sobre o desempenho acontecem em indivíduos com elevada vivência autêntica. Quando os indivíduos são mais autênticos, as informações que os mesmos recebem sobre o desempenho afetará mais fortemente o próprio processo motivacional no trabalho. Este estudo fornece evidências da relação positiva entre os recursos do trabalho e pessoais com o engajamento e o desempenho no trabalho, contribuindo, assim, para um aumento, por parte das organizações, do feedback recebido sobre o desempenho, bem como a criação de ambientes facilitadores de autenticidade.

El objetivo de esta investigación fue identificar el papel moderador de la experiencia auténtica en la relación entre la retroalimentación recibida y el desempeño de roles, mediada por el compromiso laboral. Los datos se obtuvieron de una muestra por conveniencia de trabajadores brasileños de organizaciones públicas y privadas (N = 1244). La interacción significativa entre la retroalimentación y la experiencia auténtica permitió comprender que los mayores efectos de la retroalimentación sobre el desempeño ocurren en individuos con alta experiencia auténtica. Cuando los individuos son más auténticos, la información que reciben sobre el desempeño afectará más fuertemente su propio proceso motivacional en el trabajo. Este estudio proporciona evidencia de la relación positiva entre el trabajo y los recursos personales con el compromiso y el desempeño en el trabajo, de esta forma contribuyen al aumento, por parte de las organizaciones, de la retroalimentación recibida sobre el desempeño, así como a la creación de entornos propicios de autenticidad.

The moderating effect of perceived punishment on the relationship between the Dark Triad and corruption

The present study aimed to investigate the moderating effect of perceived punishment on the relationship between the Dark Triad personality traits and corruption in Brazil (N = 118) and the United Kingdom (N = 130). Participants answered the Dark Triad Dirty Dozen Scale, as well as measures of corruption and perceived punishment. It was found that punishment predicts corruption in both countries. Regarding the Dark Triad traits, a relationship between Machiavellianism and corruption was identified in Brazil and the United Kingdom, although an interaction with punishment was identified only in Brazil. Moreover, psychopathy had no relationship with corruption or punishment in either country. A direct relationship was found only in Brazil on narcissism, although the interaction term was significant in both countries. In general, it was identified that perceived punishment and the dark triad traits contribute to the understanding of corruption, despite some differences in the results between Brazil and the United Kingdom.

O presente estudo tem como objetivo investigar o papel moderador da percepção de punição na relação entre Tríade Sombria da personalidade e corrupção no Brasil (N = 118) e no Reino Unido (N = 130). Participantes responderam à Escala Dark Triad Dirty Dozen, bem como a medidas de corrupção e percepção de punição. Foi encontrado que a punição prediz a corrupção em ambos os países. Em relação à Tríade Sombria, o relacionamento entre maquiavelismo e corrupção foi identificado no Brasil e no Reino Unido, embora a interação com a punição tenha sido identificada apenas no Brasil. Adicionalmente, a psicopatia não teve relação com a corrupção ou com a punição em nenhum dos países. Um efeito direto do narcisismo foi encontrado apenas no Brasil, apesar do termo de interação ter sido significativo em ambos os países. De forma geral, foi identificado que a percepção de punição e a tríade sombria contribuíram com a compreensão da corrupção, apesar de algumas diferenças nos resultados entre Brasil e Reino Unido.

El presente estudio tuvo como objetivo investigar el efecto moderador del castigo percibido sobre la relación entre los rasgos de personalidad de la tríada oscura y la corrupción en Brasil (N = 118) y en el Reino Unido (N = 130). Los participantes respondieron a la Escala de la Docena Sucia de la Triada Oscura, así como a medidas de corrupción y castigo percibido. Se encontró que el castigo predice la corrupción en ambos países. En cuanto a los rasgos de la tríada oscura, se identificó una relación entre el maquiavelismo y la corrupción en Brasil y en el Reino Unido, aunque se identificó una interacción con el castigo solo en Brasil. Además, la psicopatía no tuvo relación con la corrupción o el castigo en ninguno de los dos países. Se encontró una relación directa solo en Brasil con el narcisismo, aunque la interacción fue significativa en ambos países. En general, se identificó que el castigo percibido y los rasgos de la tríada oscura contribuyen a la comprensión de la corrupción, a pesar de algunas diferencias en los resultados entre Brasil y el Reino Unido.

Single Port Robotic Nephrectomy via lower anterior retroperitoneal approach: feasible, safe and effective option in surgically complex patients

ABSTRACT Purpose: Minimally invasive radical nephrectomy is often preferred for larger renal tumours not suitable for partial nephrectomy (1). When performed with a multiport robot, the procedure is routinely performed with a transperitoneal approach, with recent studies highlighting important factors for surgical outcomes, including predictive factors (2), segmental artery unclamping techniques (3), and comparisons of robotic techniques (4). This video shows that SP Robot-Assisted Radical Nephrectomy (RARN) via a lower anterior approach is valuable in challenging cases. Materials and Methods: We performed SP-RARN on two complex patients using a retroperitoneal lower anterior approach. The first patient, a 54-year-old female with a BMI of 36.8 kg/m2, had a ventral hernia and bowel obstruction history, with a 9 cm right middle kidney mass. The second patient, a 58-year-old male with a BMI of 31.19 kg/m2, had ESRD and was on peritoneal dialysis for 8 years, with a 3.4x3.7 cm mass in the right superior pole, suspected to be RCC. The surgical technique is detailed in the video. Results: Both procedures were successful, with operative times of 173 and 203 minutes and blood loss of 150 mL. No complications occurred. Patients were discharged after 31 and 38 hours, respectively. Histopathology confirmed RCC. At the 3-month follow-up, no complications or readmissions were reported. Second patient continued peritoneal dialysis without issues. Conclusion: Retroperitoneal SP-RARN via the lower anterior approach avoids the peritoneal cavity, making it suitable for certain patients. In these patients, more so than in others, this procedure is feasible, safe, and less morbid than the standard multiport approach.

Interspecific association between two primatespecies in an urban park / Associação interespecífica entre duas espécies de primatas em um parque urbano

As with Amazonian primates, mixed associations between species in the Atlantic Forest are also influenced by ecological factors. However, Atlantic Forest primates may face additional challenges, such as isolation pressures and fragmentation of forest habitats, which may increase the frequency of these arrangements. The main of this work is to report a sympatry with possible interaction between individuals of two species of primates of the Pitheciidae and Callitrichidae families: Callicebus nigrifrons (Spix 1823) and Callithrix aurita (É. Geoffroy Saint-Hilaire 1812) in an urban park in the south of the state of Minas Gerais. Individuals were observed interacting during foraging and displacement. The association of individuals of the two species can be explained by the low quality of the forest fragment, as it can increases the chances of obtaining food resources and configures a dilution strategy against predator attacks.

Assim como ocorre com os primatas amazônicos, as associações mistas entre espécies na Mata Atlântica também são influenciadas por fatores ecológicos. No entanto, os primatas da Mata Atlântica podem enfrentar desafios adicionais, como pressões de isolamento e fragmentação de habitats florestais, que podem aumentar a frequência desses arranjos. O objetivo deste trabalho é apresentar um relato de simpatia com possível interação entre indivíduos de duas espécies de primatas das famílias Pitheciidae e Callitrichidae: Callicebus nigrifrons (Spix 1823) e Callithrix Resumo aurita (É. Geoffroy Saint-Hilaire 1812) em um parque urbano no sul do estado de Minas Gerais. Foram observados indivíduos interagindo durante o forrageio e deslocamento. A associação de indivíduos das duas espécies pode ser explicada devido à baixa qualidade do fragmento florestal, pois pode aumentar as chances de obter recursos alimentares e configura uma estratégia de diluição de contra-ataques de predadores.

Uma reflexão sobre as conexões entrea fonoaudiologia e Saúde Única / A reflection on the connections betweenspeech therapy and One Health

A Saúde Única é uma crescente abordagem sistêmica para aumentar indissociavelmente os níveis de saúde das pessoas, dos animais e do ambiente no planeta. Por sua característica interdisciplinar e multidisciplinar, a Saúde Única tem arregimentado cada vez mais novos agentes na área de saúde, ampliando novas fronteiras de prática profissional. Objetivo: tendo em vista de que a abordagem sistêmica da Saúde Única (One Health) é holística, objetivou-se descrever e refletir sobre o papel da fonoaudiologia nesse contexto. Métodos: fez-se uma revisão de escopo sobre as ligações da fonoaudiologia com as desordens de saúde que são o foco em Saúde Única. Realizou-se uma procura de artigos nas plataformas PubMed e SciELO, com a combinação booleana dos indexadores "fonoaudiologia" e "Saúde Única", em idioma português; e as palavras "speech-language therapy" e "One Health" em idioma inglês. O operador booleano foi "E" e "AND". Adicionalmente, procurou-se teses e dissertações com esses mesmos operadores e combinações no Catálogo de Teses e Dissertações da CAPES. Analisou-se os dados por uma abordagem qualitativa, por isso os métodos estatísticos não foram aplicados. A partir dessa abordagem, complementou-se a argumentação com uma reflexão crítica sobre a inclusão da fonoaudiologia na estratégia de Saúde Única. Resultados: apenas na plataforma SciELO encontrou-se cinco obras com os descritores e a combinação "Saúde Única AND fonoaudiologia"; esse resultado é fortemente sugestivo de que o profissional em fonoaudiologia não tem sido incluído como um agente na abordagem Saúde Única. Contrariando esse cenário, argumenta--se que a fonoaudiologia pode preencher um nicho de trabalho e atuação acadêmica na abordagem de Saúde Única, cujo foco são desordens de saúde que podem resultar em distúrbios da comunicação nas pessoas. Considerações finais: há um nicho para a fonoaudiologia na abordagem da Saúde Única para a prevenção, o tratamento e a investigação científica das desordens da comunicação humana.

One Health is a growing systemic approach aimed at increasing the health levels of people, animals and the environment on the planet. Due to its inter- and multidisciplinary characteristics, One Health has been recruiting an increasing number of new agents in the health area, expanding new frontiers of professional practice. Objective: considering that the systemic approach of One Health is holistic, the objective is to describe and reflect on the role of speech therapy in this context. Methods: a scoping review was conducted to explore the connections between speech therapy and the health disorders that are the focus of One Health. A search for articles was carried out on the PubMed and SciELO platforms, using the Boolean combination of the terms "fonoaudiologia" (speech therapy) and "Saúde Única" (One Health), in Portuguese; and the words "speech-language therapy" and "One Health" in English using the Boolean operator "E" and "AND". Additionally, we searched for theses and dissertations with these same operators and combinations, in the CAPES Catalog of Theses and Dissertations. The data was analyzed using a qualitative approach, therefore statistical methods were not applied. Based on this approach, the argument was complemented with a critical reflection on the inclusion of speech therapy in the One Health strategy. Results: five works were found on the SciELO platform using the descriptors and combination "Saúde Única AND fonoaudiologia". This result suggests that the speech therapy professional has not been included as an agent in the One Health approach. Contrary to this scenario, it is argued that speech therapy can play a significant professional and academic role in One Health, which focuses on health disorders that may result in communication disorders. Final considerations: there is a niche for speech therapy in the One Health approach to the prevention, treatment and scientific investigation of human communication disorders.

Investigation of serum Metrnl levels in pregnant women with gestational diabetes mellitus: a prospective non-interventional cohort study

SUMMARY OBJECTIVE: The objective of this study was to investigate serum Metrnl levels in pregnant women with gestational diabetes mellitus and compare them with pregnant women without gestational diabetes mellitus. METHODS: The gestational diabetes mellitus group consisted of 87 pregnant women diagnosed with gestational diabetes mellitus, and the control group consisted of 93 healthy pregnant women without gestational diabetes mellitus. Serum Metrnl levels were determined by the enzyme-linked immunosorbent assay method. RESULTS: The two groups were similar in terms of demographic features. The median serum Metrnl level was found to be 1.16 ng/mL in the gestational diabetes mellitus group, while it was determined as 2.2 ng/mL in the control group (p=0.001). The two groups were divided into two subgroups based on participants' body mass index, normal weight and overweight. The lowest median Metrnl level was detected in the normal weight gestational diabetes mellitus group, followed by the overweight gestational diabetes mellitus group, normal weight control group, and overweight control group (1.1, 1.2, 2, and 2.4 ng/mL, respectively). Receiver operating curve analysis was performed to determine the value of the serum Metrnl level in terms of predicting gestational diabetes mellitus. The area under the curve analysis of serum Metrnl for gestational diabetes mellitus estimation was 0.768 (p=0.000, 95%CI 0.698-0.839). The optimal cutoff value for serum Metrnl level was determined as 1.53 ng/mL with 69% sensitivity and 70% specificity. CONCLUSION: Serum Metrnl levels in pregnant women with gestational diabetes mellitus were found to be significantly lower than in pregnant women without gestational diabetes mellitus. The mechanisms underlying the decrease in serum Metrnl levels in gestational diabetes mellitus remain unclear for now, and future studies will reveal the role of Metrnl in the pathophysiology of gestational diabetes mellitus.

Hailey-Hailey disease: clinical, diagnostic and therapeutic update

Abstract Hailey-Hailey disease is a rare genodermatosis described in 1939, with an autosomal dominant inheritance pattern, characterized by compromised adhesion between epidermal keratinocytes. It has an estimated prevalence of 1/50,000, with no gender or race predilection. It results from a heterozygous mutation in the ATP2C1 gene, which encodes the transmembrane protein hSPA1C, present in all tissues, with preferential expression in keratinocytes. Mutations in the ATP2C1 gene cause changes in the synthesis of junctional proteins, leading to acantholysis. It usually begins in adulthood, with isolated cases at the extremes of life. It manifests as vesico-bullous lesions mainly in the flexural areas, which develop into erosions and crusts. Chronic lesions may form vegetative or verrucous plaques. Pruritus, a burning feeling and pain are common. It evolves with periods of remission and exacerbation, generally triggered by humidity, friction, heat, trauma and secondary infections. The diagnosis is based on clinical and histopathological criteria: marked suprabasal acantholysis, loosely joined keratinocytes, giving the appearance of a "dilapidated brick wall", with a few dyskeratotic cells. The acantholysis affects the epidermis and spares the adnexal epithelia, which helps in the differential diagnosis with pemphigus vulgaris. Direct immunofluorescence is negative. The main differential diagnoses are Darier disease, pemphigus vegetans, intertrigo, contact dermatitis, and inverse psoriasis. There is no cure and the treatment is challenging, including measures to control heat, sweat and friction, topical medications (corticosteroids, calcineurin inhibitors, antibiotics), systemic medications (antibiotics, corticosteroids, immunosuppressants, retinoids and immunobiologicals) and procedures such as botulinum toxin, laser and surgery. There is a lack of controlled clinical trials to support the choice of the best treatment.

Patrones de alimentación perceptiva durante la primera infancia en conglomerados urbanos. Argentina, 2018-19 / Responsive feeding patterns during early childhood in urban areas. Argentina, 2018­2019

Introducción. La calidad de la alimentación implica tanto la cantidad y calidad de los alimentos que se ofrecen como la forma en que se ofrecen, el entorno y las respuestas de quien los ofrece. El objetivo de este trabajo fue identificar patrones de comportamiento relacionados a la alimentación perceptiva en niños entre 6 y 23 meses de áreas urbanas de la Argentina en 2018-19. Población y métodos. Análisis secundario de datos de la 2da Encuesta Nacional de Nutrición y Salud 2018-19, de una muestra probabilística polietápica de localidades urbanas de 5000 habitantes y más de Argentina. Se realizó análisis descriptivo y análisis de componentes principales para identificar los patrones de alimentación perceptiva en 4379 niños y niñas de 6 a 23 meses. Resultados. Se identificaron cinco patrones de alimentación perceptiva, las dos primeras dimensiones explicaron el 71,1 % de la inercia (p = 0,013). El patrón donde prevalecía la posibilidad de experimentación, la autonomía, la interacción y la ausencia de pantallas, premios y distracciones se asoció a niños/as mayores de 12 meses, de las regiones del centro y sur (Cuyo, Pampeana, Gran Buenos Aires y Patagonia), mientras que el patrón relacionado con menor autonomía, experimentación y autorregulación correspondió a las regiones Noroeste y Noreste, y a niños/as entre 6 y 11 meses. Conclusión. Se evidencian prácticas de alimentación perceptiva que se corresponden con patrones diferenciados entre sí, asociados a diferentes etapas y a la región donde viven los niños/as.

Introduction. Dietary quality involves both the quantity and quality of food offered, the way and the setting in which it is offered, and the responses of the person offering it. The objective of this study was to identify behavioral patterns related to responsive feeding in children aged 6 to 23 months in urban areas from Argentina in 2018­2019. Population and methods. Secondary analysis based on data from the second National Survey on Nutrition and Health of 2018­2019 conducted in a multistage probability sample from urban areas of 5000 inhabitants or more in Argentina. A descriptive analysis and a principal component analysis were performed to identify responsive feeding patterns in 4379 children aged 6 to 23 months. Results. Five responsive feeding patterns were identified; the first 2 dimensions explained 71.1% of inertia (p = 0.013). The pattern with a prevailing possibility of experimentation, autonomy, interaction, and the absence of screens, rewards and distractions was associated with children older than 12 months from the central and south regions (Cuyo, Pampa, Greater Buenos Aires, and Patagonia), whereas the pattern related to a lower autonomy, experimentation, and self-regulation corresponded to children aged 6 to 11 months from the Northwest and Northeast regions. Conclusion. There is evidence of responsive feeding practices that correspond to distinguishable patterns, associated with different stages of life and with the region where the children live

COVID-19 Computed tomography patterns in renal replacement therapy patients / Padrões de tomografia computadorizada da COVID-19 em pacientes em terapia renal substitutiva

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12-84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12-84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19.

Drenaje venoso anómalo. Vena cava superior izquierda persistente que drena en la aurícula derecha y vena cava superior derecha que drena en la aurícula izquierda: reporte de un caso / Anomalous Venous Drainage. Persistent Left Superior Vena Cava Draining into the Right Atrium and Right Superior Vena Cava Draining into the Left Atrium: Case Report

Introducción: Entre 0,3-0,5% de niños nacidos presentan una vena cava superior izquierda persistente, lo que lo hace una de las malformaciones congénitas más frecuentes del drenaje venoso. El drenaje de esta en la aurícula derecha, además del drenaje de la vena cava superior derecha en la aurícula izquierda, es extremadamente infrecuente. Caso Clínico: Se presenta el caso de un infante de 8 meses asintomático que es llevado a consulta por presentar desaturaciones. El examen físico es normal. El ecocardiograma de contraste con solución salina muestra una vena cava superior izquierda persistente que drena en la aurícula derecha y un retorno anómalo de la vena cava superior derecha. Se realiza una corrección quirúrgica y evoluciona de forma favorable. Conclusión: La presentación en simultáneo de una vena cava superior izquierda persistente que drena en la aurícula derecha y una vena cava derecha que drena en la aurícula izquierda es extremadamente rara. La mayoría de los casos registrados se diagnosticaron de manera incidental en personas adultas al no presentar síntomas.

Introduction: Between 0.3-0.5% of children born have a persistent left superior vena cava, which makes it one of the most frequent congenital malformations of venous drainage. Drainage of this vein into the right atrium, in addition to drainage of the right superior vena cava into the left atrium, is extremely rare. Clinical case: We present a case of an asymptomatic 8-month-old infant who was taken to the clinic for desaturations. Physical examination was normal. The contrast echocardiogram with saline solution showed a persistent left superior vena cava draining into the right atrium and an anomalous return of the right superior vena cava. Surgical correction was performed and the patient evolved favorably. Conclusion: The simultaneous presentation of a persistent left superior vena cava draining into the right atrium and a right superior vena cava draining into the left atrium is extremely rare. Most of the reported cases were diagnosed incidentally in adults in the absence of symptoms.

Riesgo de eventos embólicos en pacientes con miocardiopatía chagásica y fibrilación auricular a pesar de terapia antitrombótica: ¿es la anticoagulación suficiente? / Risk of Embolic Events in Patients with Chagasic Cardiomyopathy and Atrial Fibrillation Despite Antithrombotic Therapy: Is Anticoagulation Enough?

RESUMEN Introducción: La miocardiopatía chagásica (MC) difiere de otras causas de insuficiencia cardíaca en múltiples aspectos, destacándose el riesgo de embolias sistémicas. Sin embargo, pocos estudios han evaluado el riesgo de eventos embólicos en pacientes anticoagulados con MC en comparación con otras miocardiopatías. Objetivo: Nuestro objetivo fue analizar la incidencia de embolias sistémicas en una cohorte de pacientes anticoagulados con diagnóstico de fibrilación auricular (FA) con y sin MC. Material y métodos: Se realizó un estudio de cohorte retrospectivo en hospital de cuarto nivel en Colombia durante el periodo 2014-2020. Se incluyeron todos los pacientes con diagnóstico de miocardiopatía de cualquier etiología y FA que estuvieran en régimen de anticoagulación. El resultado primario fue la incidencia de eventos embólicos. Se realizó un análisis de supervivencia mediante modelos de riesgos proporcionales de Cox ajustados. Un valor de p <0,05 se consideró significativo. Todas las pruebas estadísticas fueron de dos colas. Resultados: Se evaluaron 149 pacientes anticoagulados con miocardiopatía (mediana de edad: 71 años; mujeres: 30,20%). La incidencia acumulada de eventos embólicos fue significativamente mayor en los pacientes con MC (17,50%) en comparación con aquellos con otras miocardiopatías (4,95%), a pesar de que estos últimos tenían una puntuación CHA2DS2-VASc significativamente mayor (p=0,013). Tras el análisis multivariado, los pacientes con MC tuvieron un riesgo significativamente mayor de eventos embólicos independientemente de la puntuación CHA2DS2-VASc y del tipo de anticoagulante prescrito (HR 5,65; IC 95% 1,46-21,83; p=0,012). Conclusiones: La MC se asoció con un riesgo significativamente mayor de eventos embólicos, a pesar del tratamiento anticoagulante en ambos grupos. Se requiere más investigación para comprender el origen de este riesgo observado y traducir este conocimiento en indicaciones específicas de anticoagulación para pacientes con MC.

ABSTRACT Background: Chagasic cardiomyopathy (CC) differs from other heart failure causes in multiple aspects, highlighting the risk of systemic embolisms. However, few studies have evaluated the risk of embolic events in anticoagulated patients with CC compared with other cardiomyopathies. Objective: We aimed to analyze the incidence of systemic embolisms in a cohort of anticoagulated patients diagnosed with atrial fibrillation (AF) with and without CC. Methods: A retrospective cohort study was carried out at a fourth level hospital in Colombia during the period 2014-2020. All patients diagnosed with cardiomyopathy of any etiology and AF, who were on an anticoagulation regimen were included. The primary outcome was the incidence of embolic events. A survival analysis was performed using adjusted Cox proportional hazard models. A p-value <0.05 was considered significant. All statistical tests were two-tailed. Results: A total of 149 anticoagulated patients with cardiomyopathy were evaluated (median age: 71 years; women: 30.20%). The cumulative incidence of embolic events was significantly higher in patients with CC (17.50%) compared with those presenting other cardiomyopathies (4.95%), despite that the latter had a significantly higher CHA2DS2-VASc score (p=0.013). After multivariate analysis, patients with CC had a significantly higher risk of embolic events regardless of the CHA2DS2-VASc score and the type of anticoagulant prescribed (HR 5.65; 95% CI 1.46-21.83; p=0.012). Conclusions: Chagasic cardiomyopathy was associated with a significantly higher risk of embolic events, despite anticoagulation therapy in both groups. More research is required to understand the origin of the risk observed in order to translate this knowledge into specific indications for anticoagulation in patients with CC.

Relationship between video game addiction and bladder/bowel dysfunction in children / Relación entre la adicción a los videojuegos y la disfunción vesical o intestinal en niños

Abstract Introduction. Video games have a strong influence on children and adolescents. Video game addiction has negative effects on children's health. Objective. To determine the relationship between video game addiction and bladder/bowel dysfunction in children. Materials and methods. Three hundred sixty-three children and their mothers who met the inclusion criteria constituted the sample of this correlational study. The data were collected using a descriptive information form, the Video Game Addiction Scale for Children, and the Childhood Bladder and Bowel Dysfunction Questionnaire. Results. We found that 72.5% of the children were nine years old and 27.5% were ten years old; 50.4% were males and 49.6% were female. While 4.7% of the children who participated in the study were underweight, 19.6% were overweight, and 17.9% were obese. The mean Video Game Addiction Scale for Children score was 50.77 ± 16.17, whereas the mean Childhood Bladder and Bowel Dysfunction Questionnaire score was 29.98 ± 8.90. The ratio of children with a mean Video Game Addiction Scale for Children scores equal to or greater than 90 was 0.8% (n = 3). We found that 3.6% (n = 13) of the children had urinary/fecal incontinence while playing video games. There was a weak positive relationship between the dimensions of the Video Game Addiction Scale for Children scores, the Childhood Bladder and Bowel Dysfunction Questionnaire scores, and children's bladder and bowel function (r = 0.220; p < 0.05). Conclusions. There is a correlation between children's video game addiction level and their bladder and bowel dysfunction grade. Higher video game addiction levels correspond to higher bladder and bowel dysfunction.

Resumen Introducción. Los videojuegos tienen una fuerte influencia en los niños y adolescentes. La adicción a ellos tiene efectos perjudiciales para la salud de los niños. Objetivo. Determinar la relación entre la adicción a los videojuegos y la disfunción vesical o intestinal en niños. Materiales y métodos. Los 373 niños y sus madres que cumplieron con los criterios de inclusión constituyeron la muestra de este estudio descriptivo y correlacional. Los datos se recopilaron mediante un formulario de información descriptiva, la Video Game Addiction Scale for Children y el Childhood Bladder and Bowel Dysfunction Questionnaire. Resultados. El 72,5 % de los niños tenía nueve años y, el 27,5 %, diez; el 50,4 % eran hombres y el 49,6 %, mujeres. El 4,7 % de los estudiantes que participaron en el estudio tenían bajo peso, el 19,6 % presentaba sobrepeso y el 17,9 % tenía obesidad. Se constató que las puntuaciones medias de las escalas fueron 50,77 ± 16,17 para la Video Game Addiction Scale for Children y 29,98 ± 8,90 para el Childhood Bladder and Bowel Dysfunction Questionnaire. La proporción de niños con una puntuación de 90 o superior en la dicha escala fue del 0,8 % (n = 3). Se encontró que el 3,6 % (n = 13) de los niños tenía incontinencia urinario-fecal mientras jugaba videojuegos. Se reveló que había una correlación positiva débil entre las dimensiones de las dos escalas evaluadas, y la función de la vejiga y el intestino (p < 0,05). Conclusiones. El grado de adicción a los videojuegos de los niños está correlacionado con su grado de disfunción vesical o intestinal: entre mayor sea la adicción, mayor es la disfunción.
