RESUMO

Background: Due to the copious disposal of plastics, marine ecosystems receive a large part of this waste. Microplastics (MPs) are solid particles smaller than 5 millimeters in size. Among the plastic polymers, polystyrene (PS) is one of the most commonly used and discarded. Due to its density being greater than that of water, it accumulates in marine sediments, potentially affecting benthic communities. This study investigated the ingestion of MP and their effect on the meiofauna community of a sandy beach. Meiofauna are an important trophic link between the basal and higher trophic levels of sedimentary food webs and may therefore be substantially involved in trophic transfer of MP and their associated compounds. Methods: We incubated microcosms without addition of MP (controls) and treatments contaminated with PS MP (1-µm) in marine sediments at three nominal concentrations (103, 105, 107particles/mL), for nine days, and sampled for meiofauna with collections every three days. At each sampling time, meiofauna were collected, quantified and identified to higher-taxon level, and ingestion of MP was quantified under an epifluorescence microscope. Results: Except for Tardigrada, all meiofauna taxa (Nematoda, turbellarians, Copepoda, Nauplii, Acari and Gastrotricha) ingested MP. Absorption was strongly dose dependent, being highest at 107 particles/mL, very low at 105 particles/mL and non-demonstrable at 103 particles/mL. Nematodes accumulated MP mainly in the intestine; MP abundance in the intestine increased with increasing incubation time. The total meiofauna density and species richness were significantly lower at the lowest MP concentration, while at the highest concentration these parameters were very similar to the control. In contrast, Shannon-Wiener diversity and evenness were greater in treatments with low MP concentration. However, these results should be interpreted with caution because of the low meiofauna abundances at the lower two MP concentrations. Conclusion: At the highest MP concentration, abundance, taxonomic diversity and community structure of a beach meiofauna community were not significantly affected, suggesting that MP effects on meiofauna are at most subtle. However, lower MP concentrations did cause substantial declines in abundance and diversity, in line with previous studies at the population and community level. While we can only speculate on the underlying mechanism(s) of this counterintuitive response, results suggest that further research is needed to better understand MP effects on marine benthic communities.

RESUMO

This article presents an ingestion procedure towards an interoperable repository called ALPACS (Anonymized Local Picture Archiving and Communication System). ALPACS provides services to clinical and hospital users, who can access the repository data through an Artificial Intelligence (AI) application called PROXIMITY. This article shows the automated procedure for data ingestion from the medical imaging provider to the ALPACS repository. The data ingestion procedure was successfully applied by the data provider (Hospital Clínico de la Universidad de Chile, HCUCH) using a pseudo-anonymization algorithm at the source, thereby ensuring that the privacy of patients' sensitive data is respected. Data transfer was carried out using international communication standards for health systems, which allows for replication of the procedure by other institutions that provide medical images. OBJECTIVES: This article aims to create a repository of 33,000 medical CT images and 33,000 diagnostic reports with international standards (HL7 HAPI FHIR, DICOM, SNOMED). This goal requires devising a data ingestion procedure that can be replicated by other provider institutions, guaranteeing data privacy by implementing a pseudo-anonymization algorithm at the source, and generating labels from annotations via NLP. METHODOLOGY: Our approach involves hybrid on-premise/cloud deployment of PACS and FHIR services, including transfer services for anonymized data to populate the repository through a structured ingestion procedure. We used NLP over the diagnostic reports to generate annotations, which were then used to train ML algorithms for content-based similar exam recovery. OUTCOMES: We successfully implemented ALPACS and PROXIMITY 2.0, ingesting almost 19,000 thorax CT exams to date along with their corresponding reports.

RESUMO

The study aimed to understand the feeding behavior of Neotropical brown stink bug nymphs Euschistus heros (F.) on soybean plants during vegetative stage through electropenetrography (EPG) technique. Three distinct phases were identified: non-feeding, pathway, and ingestion. Waveforms representing these phases were consistent across nymphal instars and plant structures, and named Np, Eh1, and Eh2, respectively. Biological interpretations of the waveforms were proposed by integrating visual observations, comparisons with adult waveforms, and histological studies. The waveforms Np, Eh1, and Eh2 were associated with resting/walking, initial stylet-plant contact, and xylem sap ingestion, respectively. Notably, nymphs showed a higher number of Eh1 events and longer durations when feeding on petioles compared to leaves, particularly in younger instars. However, differences between instars diminished in older nymphs. Fifth instars consistently exhibited the highest Eh1 values, and displayed longer xylem ingestion durations compared to other instars. Second instars demonstrated increased xylem ingestion events on petioles compared to leaves. Across plant structures, on petioles, nymphs generally showed longer xylem ingestion durations than on leaf surfaces. Fifth instar consistently had the longest ingestion durations overall. Additionally, statistical differences in xylem ingestion duration were observed between instars within each plant structure, with fifth instars displaying the longest durations. These findings offer valuable insights into the feeding behavior of E. heros nymphs, which could inform the development of more effective pest management strategies for soybean crops.

RESUMO

Background: Bevacizumab together with 5-fluorouracil and oxaliplatin inhibit microvascular growth of tumor blood vessels and tumor proliferation. Few reports state the effect of these therapeutic schemes on salivary glands. Materials and Methods: Food consumption, body weight and salivary amylase activity were assessed in the submandibular gland of rats. Adult male Wistar rats, of three months old with 350/400 grams body weight, under 12-hour light/dark cycles respectively, were divided into the following experimental groups: G1) Control group, G2) 5-Fluorouracil and leucovorin calcium treated group, G3) Bevacizumab treated group, G4) Oxaliplatin treated group, G5) Bevacizumab, oxaliplatin, 5-fluorouracil and leucovorin calcium treated group and G6) Drug-free paired feeding treated group. Assessment of treatment effect was performed by one-way ANOVA. A value of p<0.05 was set for statistical significance. Results: Salivary amylase activity in gland homogenate was G1: 137.9 ± 4.64, G2: 60.95±4.64, G3: 120.93 ± 4.96, G4: 26.17 ±4.64, G5: 10.77 ±4.64 and G6: 82.87 ±4.64 U/mg protein (mean ± S.D.) Amylase activity in the G1 group was higher relative to the other experimental groups p<0.0001. Conclusions: The drugs 5-fluorouracil and oxaliplatin altered salivary amylase activity by serous granules of the submandibular gland interpreted as a mechanism of impaired acinar function. Bevacizumab administered in isolation did not alter salivary amylase activity compared to the control group. While the lower intake of the matched feeding group affected salivary amylase activity compared to the control group, the effect was significantly greater in animals treated with the oncology drugs used in the present animal model.


Antecedentes: Bevacizumab, junto con 5-fluorouracilo y oxaliplatino, inhiben el crecimiento microvascular de los vasos sanguíneos tumorales y la proliferación tumoral. Pocos reportes establecen el efecto de estos esquemas terapéuticos sobre las glándulas salivales. Materiales y Métodos: Se evaluaron el consumo de alimentos, el peso corporal y la actividad de amilasa salival en la glándula submandibular de ratas Wistar macho adultas, de tres meses de edad con 350/400 gramos de peso corporal, bajo ciclos de luz/oscuridad de 12 horas respectivamente, se dividieron en los siguientes grupos experimentales: G1) Grupo control, G2) Grupo tratado con 5-Fluorouracilo y Leucovorina cálcica. , G3) Grupo tratado con bevacizumab, G4) Grupo tratado con oxaliplatino, G5) Grupo tratado con bevacizumab, oxaliplatino, 5-fluorouracilo y leucovorina cálcica y G6) Grupo tratado con alimentación emparejada sin fármacos. La evaluación del efecto del tratamiento se realizó mediante ANOVA unidireccional. Se estableció un valor de p<0,05 para significación estadística. Resultado: La actividad de amilasa salival en homogeneizado de glándula fue G1: 137,9 ± 4,64, G2: 60,95 ± 4,64, G3: 120,93 ± 4,96, G4: 26,17 ± 4,64, G5: 10,77 ± 4,64 y G6: 82,87 ± 4,64 U/mg de proteína (media ± S.E.). La actividad de amilasa en el grupo G1 fue mayor en relación con los otros grupos experimentales p<0,0001. Conclusión: Los fármacos 5-fluorouracilo y oxaliplatino alteraron la actividad de la amilasa salival mediante gránulos serosos de la glándula submandibular interpretados como un mecanismo de deterioro de la función acinar. Bevacizumab administrado de forma aislada no alteró la actividad de la amilasa salival en comparación con el grupo de control. Mientras que la menor ingesta del grupo de alimentación combinada afectó la actividad de la amilasa salival en comparación con el grupo de control, el efecto fue significativamente mayor en los animales tratados con los medicamentos oncológicos utilizados en el grupo. modelo animal actual.

Describir la prevalencia de consumo de alimentos ultraprocesados en menores de 2 años e identificar factores asociados. Describir la proporción que los alimentos ultraprocesados representan del número total de los alimentos consumidos en el día. Métodos. Análisis secundario de los datos de niños entre 6 y 23 meses de edad con al menos un recordatorio de 24 horas de consumo de alimentos de la Segunda Encuesta Nacional de Nutrición y Salud de Argentina del año 2018. Se estudiaron como variables principales: "consumo de alimentos ultraprocesados" (según el sistema NOVA) categorizada en sí/no y la "proporción de ultraprocesados del total de alimentos consumidos". Los factores asociados explorados fueron lactancia materna, sexo, edad y el número de alimentos no ultraprocesados consumidos. Se realizó un modelo de regresión logística multivariable y se aplicó un factor de expansión para ponderar los datos. Resultados. Se incluyeron 4224 niños (ponderado 908 104). La prevalencia de consumo de ultraprocesados fue del 90,8 % (IC95%: 89,5-92) y fue asociado con mayor edad (OR 3,21; IC95% 2,28-4,52) y con el número de alimentos no ultraprocesados consumidos (OR 1,17; IC95% 1,13-1,23). Los ultraprocesados representaron una mediana del 20 % (RIC: 12,5-28,6 %) del total de alimentos consumidos en el día. Conclusiones. Este estudio señala la alta penetración de los alimentos ultraprocesados en la alimentación complementaria.


Introduction. The availability of data on the consumption of ultra-processed foods among children is important for planning public policies. Objectives. To describe the prevalence of consumption of ultra-processed foods in children under 2 years of age and identify associated factors. To describe the proportion that ultra-processed foods represent out of the total number of foods consumed in a day. Methods. Secondary analysis of data from children aged 6­23 months with at least a 24-hour recall of food consumption based on the Second National Survey on Nutrition and Health of Argentina (2018). The following primary variables were studied: "consumption of ultra-processed foods" (according to the NOVA system) categorized into yes/no and "proportion of ultra-processed out of total foods consumed." The following associated factors were studied: breastfeeding, sex, age, and number of non-ultra-processed foods consumed. A multivariate logistic regression model was developed and an expansion factor was applied to weight the data. Results. A total of 4224 children were included (weighed: 908 104). The prevalence of ultra-processed food consumption was 90.8% (95% CI: 89.5­92) and was associated with an older age (OR: 3.21, 95% CI: 2.28­4.52) and the number of non-ultra-processed foods consumed (OR: 1.17, 95% CI: 1.13­1.23). Ultra-processed foods accounted for a median 20% (IQR: 12.5­28.6%) of all foods consumed in a day. Conclusions. This study highlights the high penetration of ultra-processed foods in complementary feeding.

RESUMO

Bioindicator species are useful to monitor wildlife exposure to plastic pollution, and responses to plastic leakage and policy interventions. Here we explore the biomonitoring potential of different seabird and shorebirds species across six years of monitoring in Brazil. Using the necropsy stranding database of the Beach Monitoring Project of the Santos Basin (PMP-BS), we evaluated i) the frequency of birds-plastic interactions in Brazil; ii) whether plastic interactions have changed through time and in different coastal regions; and iii) potential bioindicators for monitoring the exposure of seabirds to plastic in the nearshore South Atlantic Ocean. We found 37 species that had ingested plastic, including ten new records, found that the rates of tube-nosed seabirds increased through time, and suggested two potential species. We discuss the potential for biomonitoring marine pollution in the South Atlantic Ocean using PMP-BS, providing a scheme for a better plastic pollution monitoring in Brazil.

RESUMO

Pacientes com transtornos alimentares (TAs) são considerados mais vulneráveis ao sofrimento psíquico induzido pela pandemia de Covid-19. Este estudo teve como objetivo analisar as repercussões do isolamento social na saúde física e mental de pacientes com diagnóstico de TAs durante o primeiro ano da pandemia de Covid-19 e investigar suas reações à mudança do atendimento presencial para o online. Trata-se de uma pesquisa qualitativa, descritiva e exploratória, com delineamento longitudinal. Participaram 13 pacientes do sexo feminino, com idades entre 13 e 66 anos, em seguimento ambulatorial em um serviço vinculado ao Sistema Único de Saúde (SUS). Os dados foram colhidos de forma remota, por meio de um formulário aplicado e reaplicado em um intervalo de seis meses. Os resultados foram submetidos à análise temática reflexiva e agrupados em quatro categorias centrais: adaptação às condições de isolamento social; repercussões emocionais ao escutar o persistente rumor da morte; qualidade da alimentação, gestão das emoções e nível de insatisfação corporal; e facilidades e barreiras percebidas na transição para o atendimento online. Os achados evidenciam marcada vulnerabilidade psicossocial, que se reflete na piora de sintomas preexistentes e no aparecimento de novos sofrimentos psíquicos, indicando a necessidade de intensificar o acompanhamento terapêutico no período pandêmico, de acordo com as adaptações requeridas.(AU)


Patients with eating disorders (EDs) are considered more vulnerable to pandemic-induced psychological distress due to COVID-19 pandemic. This study aimed to analyze the repercussions of social isolation on the physical and mental health of patients diagnosed with EDs during the first year of the COVID-19 pandemic and to investigate their reactions to the shift from face-to-face to online care. This is a qualitative, descriptive, and exploratory research with a longitudinal design. In total, 13 female patients aged from 13 to 66 years and who were in outpatient follow-up participated in this research. Data were remotely collected using a form applied and reapplied at a six-month interval. Results were subjected to thematic reflective analysis and grouped into four central categories: Adaptation to conditions of social isolation; Emotional repercussions: listening to the persistent rumor of death; Quality of food, management of emotions, and level of body dissatisfaction; Transition to online care: perceived facilities and barriers. Results show marked psychosocial vulnerability, which is reflected in the worsening of preexisting symptoms and the emergence of new psychological suffering, indicating the need to intensify the monitoring in this period, according to the adaptations required by the pandemic scenario.(AU)


Los pacientes con trastornos de la conducta alimentaria (TCA) están más vulnerables al sufrimiento psíquico inducido por la pandemia de la Covid-19. Este estudio tuvo como objetivo analizar las repercusiones del aislamiento social en la salud física y mental de pacientes con diagnóstico de TCA durante el primer año de la pandemia de Covid-19 e investigar sus reacciones al cambio de la atención presencial a la online. Se trata de una investigación cualitativa, descriptiva y exploratoria, con diseño longitudinal. Participaron 13 pacientes mujeres, con edades de entre 13 y 66 años, en seguimiento en un servicio vinculado al Sistema Único de Salud (SUS). Los datos se recogieron de manera remota mediante un formulario aplicado y reaplicado en un intervalo de seis meses. Los resultados se sometieron a análisis temático reflexivo y se agruparon en cuatro categorías centrales: Adaptación a las condiciones de aislamiento social; Repercusiones emocionales en la escucha del persistente rumor de la muerte; calidad de la alimentación, gestión de las emociones y nivel de insatisfacción corporal; y facilidades y obstáculos percibidos en la transición a la atención en línea. Los resultados muestran una marcada vulnerabilidad psicosocial, que se refleja en el empeoramiento de los síntomas preexistentes y en la aparición de nuevos sufrimientos psicológicos, lo que indica la necesidad de intensificar el seguimiento, de acuerdo con las adaptaciones requeridas.(AU)

RESUMO

ABSTRACT Background: People recurrently have difficulties swallowing solid medications, which can be associated with the size of the medication and the age and gender of individuals. Objective: To evaluate the impact of capsule size and adults' age and gender on oral and pharyngeal capsule transit during capsule swallows. Methods: Videofluoroscopy was used to measure capsule oral and pharyngeal transit during swallows in 49 healthy individuals (17 men and 32 women), with a mean age of 46 years (ranging from 23 to 88 years). Smaller capsules were filled with 0.50 mL of barium sulfate, and larger capsules were filled with 0.95 mL of barium sulfate; the volume of liquid ingested with the capsules was also quantified in each ingestion. The measurements included the oral preparation time, oral transit time, swallowing reaction time, time to laryngeal vestibule closure, laryngeal vestibule closure duration, pharyngeal transit time, and upper esophageal sphincter opening duration. Results: The capsule size did not influence either the oral or pharyngeal transit time. Increased liquid volume was ingested with larger capsules and by people older than 40 years. The oral transit time was shorter in older adults (60-88 years), and the time to laryngeal vestibule closure was longer in women. Conclusion: The size of large capsules did not make a difference in oral or pharyngeal transit when compared with smaller capsules. The capsule size and the participant's age influenced the volume of liquid ingested - larger capsules and older individuals required a larger volume. The capsule oral transit was faster in individuals older than 60 years.


RESUMO Contexto: Algumas pessoas apresentam recorrentemente dificuldades para engolir medicamentos sólidos, o que pode estar associado ao tamanho do medicamento, à idade e ao gênero dos indivíduos. Objetivo: Avaliar, em adultos, o impacto do tamanho da cápsula, da idade e do gênero no trânsito oral e faríngeo de cápsulas. Métodos: Videofluoroscopia foi utilizada para medir o trânsito oral e faríngeo de cápsulas em 49 indivíduos saudáveis (17 homens e 32 mulheres), com idade média de 46 anos (limites de 23 e 88 anos). Cápsulas menores foram preenchidas com 0,50 mL e cápsulas maiores foram preenchidas com 0,95 mL de sulfato de bário; o volume de líquido ingerido com as cápsulas foi quantificado em cada ingestão. Foram medidos o tempo de preparo oral, tempo de trânsito oral, tempo de reação da deglutição, tempo para fechamento do vestíbulo laríngeo, tempo de fechamento do vestíbulo laríngeo, tempo de trânsito faríngeo e tempo de abertura do esfíncter superior do esôfago. Resultados: O tamanho da cápsula não influenciou o tempo de trânsito oral ou faríngeo. Mais líquido foi ingerido com cápsulas maiores e por pessoas com mais de 40 anos. O tempo de trânsito oral foi menor em idosos (60-88 anos) e o tempo de fechamento do vestíbulo laríngeo foi maior em mulheres. Conclusão: O tamanho da cápsula não influenciou o trânsito oral e faríngeo, porém houve maior volume de líquido ingerido com a cápsula maior e nos mais idosos. O trânsito oral da cápsula foi mais rápido em indivíduos com mais de 60 anos.

RESUMO

Abstract Wildlife roadkill surveys in Brazil often focus on birds, as they are one of the main groups affected by road accidents. In addition roadkill, anthropogenic litter also contributes to a significant number of bird fatalities every year. The present study aimed to investigate the stomach contents and possible contamination by inorganic material of birds killed on a federal highway that crosses the Serra de Itabaiana National Park in the state of Sergipe, Brazil. Monitoring and data collection were carried out from January to June 2022, with a motorcycle at an average speed of 60 km/h. The collected animals were transported to the Institute of Technology and Research, located at the Tiradentes University, Sergipe, Brazil, and a plastic material was identified. The plastic material found was subjected to Fourier Transform Infrared Spectroscopy (FTIR), which showed a similar wavenumber to a polymer in the polypropylene chain, very common in plastic packaging. The presence of plastics and metals in the intestinal contents of Caracara plancus and Crotophaga ani is noteworthy, as they have a greater tendency to ingest plastics due to their generalist diet. Plastic contamination in Progne chalybea and Nyctidromus albicollis probably occurred through bioaccumulation, from the consumption of insects contaminated by microplastics.


Resumo As pesquisas sobre atropelamentos de animais silvestres no Brasil geralmente se concentram nas aves, pois elas são um dos principais grupos afetados por acidentes rodoviários. Além dos atropelamentos, o lixo antropogênico também contribui para um número significativo de mortes de aves todos os anos. O presente estudo teve como objetivo investigar o conteúdo estomacal e possível contaminação por material inorgânico de aves atropeladas em uma rodovia federal que atravessa o Parque Nacional da Serra de Itabaiana, no estado de Sergipe, Brasil. O monitoramento e a coleta de dados foram realizados no período de janeiro a junho de 2022, com uma motocicleta a uma velocidade média de 60 km/h. Os animais coletados foram transportados para o Instituto de Tecnologia e Pesquisa situado na Universidade Tiradentes, Sergipe, Brasil, onde foi identificado um material plástico. O material plástico encontrado foi submetido à espectroscopia no infravermelho com transformada de Fourier (FTIR), que mostrou número de onda semelhante a um polímero da cadeia do polipropileno, muito comum em embalagens plásticas. Chama a atenção a presença de plásticos e metais no conteúdo intestinal de Caracara plancus e Crotophaga ani, pois apresentam maior tendência à ingestão de plásticos devido à dieta generalista. A contaminação plástica em Progne chalybea e Nyctidromus albicollis provavelmente ocorreu por bioacumulação, a partir do consumo de insetos contaminados por microplásticos.

RESUMO

Los trastornos por evitación/restricción de la ingesta, han sido ampliamente descritos por la similitud en sus características y las consecuencias que estas traen sobre el desarrollo crecimiento de los niños que lo experimentan. La alimentación exigente es un trastorno de tipo multifactorial, en donde los niños muestran comportamientos negativos frente a la comida o tienen preferencia por un grupo de alimentos. Esta revisión narrativa de la literatura tiene como objetivo presentar las últimas investigaciones relacionadas con la alimentación exigente, ofreciendo una guía sobre signos y síntomas, evaluación e intervención en los niños con alimentación exigente realizada por el equipo multiprofesional. La revisión de literatura fue conducida en las bases de datos PubMed y Scopus, aplicando como principal criterio de inclusión artículos en inglés, español y portugués, sobre alimentación exigente en niños entre el nacimiento y los 5 años. Los resultados de esta revisión apuntan que la alimentación exigente estaría determinada por tres estadios importantes en la vida del niño; la gestación, la fase temprana de alimentación y las experiencias durante su segundo año de vida, por lo tanto, se requiere reconocer las señales de alerta (rechazo a comer determinados alimentos, falta de habilidades para alimentarse, duración excesiva durante los tiempo de alimentación etc.,), lo que permite realizar una evaluación temprana, que guie la intervención terapéutica, favoreciendo así una alimentación segura y eficaz para la nutrición y calidad de vida del niño.


Avoidant/Restrictive Food Intake Disorders have been widely described due to the similarity in their characteristics and the consequences they have on the development and growth of children who experience them. Picky eating is a multifactorial disorder where children exhibit negative behaviors towards food or show preference for a specific group of foods. This narrative literature review aims to present the latest research related to picky eating, offering guidance on signs and symptoms, assessment, and intervention in children with picky eating conducted by a multidisciplinary team. The literature review was conducted using the PubMed and Scopus databases, with the main inclusion criterion being articles in English, Spanish, and Portuguese, on picky eating in children from birth to 5 years old. The results of this review suggest that picky eating is determined by three important stages in a child's life; gestation, the early phase of feeding, and experiences during their second year of life. Therefore, it is necessary to recognize warning signs (refusal to eat certain foods, lack of feeding skills, excessive duration during feeding times, etc.), which allows for an early assessment that guides therapeutic intervention, thus promoting safe and effective feeding for the nutrition and quality of life of the child.

RESUMO

ABSTRACT Background: Children who experience alkaline injury are at risk for the development of esophageal strictures and the need for esophageal dilations. Objective: We aimed to assess predictors for a higher number of esophageal dilatations in children following alkali ingestion. Methods: Single-center retrospective cohort study including children who underwent esophagogastroduodenoscopy (EGD) after alkali ingestion. Possible predictive factors for the need for esophageal dilatations were evaluated. Results: A total of 34 patients were included, and 19 were female (55.9%). The median age at the time of the accidents was 20.6 months (IQR 15-30.7). All alkali ingestions were accidental, in all cases involving liquid products, and most (24/34; 70%) occurred at the child's home. Homemade liquid soap was the agent in half of the cases. The most frequently reported symptom at presentation was vomiting (22/34, 64.7%). The median follow-up time was 3.2 years (IQR 1.1-7.4). On follow-up, the median number of esophageal dilatations required for these patients was 12.5 (IQR 0-34). Among demographic factors, male gender (P=0.04), ingestion of homemade products (P<0.01), and accidents happening outside of the household environment (P=0.02) were associated with a greater number of esophageal dilations on follow-up. An endoscopic classification Zargar of 2B or higher (P=0.03), the presence of stricture at the time of the second EGD (P=0.01), and gastroesophageal reflux disease (GERD) as a late complication (P=0.01) were also associated with a greater number of esophageal dilations on long term follow-up. Conclusion: Beyond the endoscopic classification severity - a well-known risk factor for the strictures after alkali ingestions, we found that male gender, accidents with homemade products, and accidents occurring outside the household environment were significantly associated with a greater number of esophageal dilatations in the long-term follow-up of children following alkali ingestion.


RESUMO Contexto: Crianças que sofrem lesões cáusticas correm alto risco de desenvolver estenose esofágica e necessidade de dilatações esofágicas. Objetivo: Objetivamos avaliar preditores de necessidade de maior número de dilatações esofágicas em crianças, após uma ingestão cáustica. Métodos: Estudo de coorte retrospectivo de centro único incluindo crianças submetidas a esofagogastroduodenoscopia (EGD) após ingestão cáustica. Foram avaliados possíveis fatores preditivos para a necessidade de dilatações esofágicas. Resultados: Foram incluídos 34 pacientes, 19 do sexo feminino (55,9%). A idade mediana no momento dos acidentes foi de 20,6 meses (IQR 15-30,7). Todas as ingestões cáusticas foram incidentais, de substâncias líquidas, e a maioria dos acidentes (24/34; 70%) ocorreu no domicílio da criança. Em metade dos casos, a substância ingerida foi um sabão caseiro. O sintoma mais reportado na apresentação foi vômito (22/34 -64,7%). O tempo médio de acompanhamento foi de 3,2 anos (IQR 1,1- 7,4). No seguimento, o número médio de dilatações esofágicas necessárias foi de 12,5 (IQR 0-34). Entre os fatores demográficos, o sexo masculino (P=0,04), acidentes com produtos caseiros (P=<0,01) e a localização do acidente fora do ambiente domiciliar (P=0,02) foram associados a um maior número de dilatações esofágicas no seguimento. A classificação endoscópica Zargar 2B ou mais (P=0,03), a presença de estenose na segunda EGD (P=0,01) e a DRGE como complicação tardia (P=0,01) também se associaram a maior número de dilatações esofágicas no acompanhamento a longo prazo. Conclusão: Além da gravidade da classificação endoscópica - fator de risco bem conhecido para as estenoses após ingestão de cáusticos, observamos que o sexo masculino, os acidentes com produtos caseiros e os acidentes ocorridos fora do ambiente doméstico foram fatores significativamente associados a um maior número de dilatações esofágicas em acompanhamento em longo prazo de crianças após ingestão de soda cáustica.

RESUMO

Abstract Avoidant or Restrictive Food Intake Disorder (ARFID) is an eating disorder (ED) not common in adults. In this article we present a clinical case of ARFID in a 37-year-old male patient treated in an ED center in Medellin, Colombia; displaying anxious symptoms that began a year earlier and concomitant weight loss, following a traumatic event causing an overall impairment with that patient. Several medical evaluations/examinations looking for organic causes, were excluded. Interventions were implemented by a psychiatry, a psychotherapist using cognitive-behavior therapy (CBT), and a nutritionist, all in face-to-face modality, which were carried out weekly for the first three months, then biweekly and subsequently quarterly. each lasting approximately 40-60 minutes. After the set of pharmacological interventions and psychotherapy, a great improvement in the functionality of the patient was observed. Improvement was found with respect to eating in public, food variation and panic attacks. In the absence of guidelines, it is important to use standardized and replicable treatments in this population.


Resumen El trastorno evitativo restrictivo de la ingesta (TERIA) es un trastorno alimentario (TCA) raro en adultos. Se presenta el caso de un hombre de 37 años con TERIA y trastorno de pánico atendido en un centro para TCA en Medellín, Colombia, quien presentó un año de síntomas ansiosos y pérdida de peso después de evento traumático, generando disfuncionalidad. Fue evaluada y excluida organicidad. Se realizaron intervenciones por parte de psiquiatría, psicoterapia con enfoque cognitivo conductual y nutrición, todas en modalidad presencial, las cuales se realizaron semanalmente los primeros tres meses, luego quincenalmente y posteriormente trimestralmente. Cada una con una duración de 40-60 minutos aproximadamente por sesión. Posterior al conjunto de intervenciones farmacológicas y psicoterapia, se observó una gran mejoría la funcionalidad del paciente, se encontró mejoría con respecto a comer en público, variación en los alimentos y ataques de panico. Ante la ausencia de guías de manejo de TERIA en adultos es relevante realizar tratamientos estandarizados que puedan ser replicados.

RESUMO

Objetivo: Determinar la relación entre la erosión dental y el consumo de bebidas refrescantes en escolares de 12 a 16 años del Centro Educativo Juan Velasco Alvarado, en el distrito de Pillco Marca, Perú. Materiales y métodos: Se realizó un estudio observacio- nal, transversal de una muestra de 135 niños de 12 a 16 años. Se seleccionaron historias clínicas que contaran con datos so- bre variables demográficas, la valoración del tipo de erosión dental según la clasificación de Eccles y que hayan respondi- do la encuesta sobre el consumo de las bebidas refrescantes (gaseosas, rehidratantes y jugos). Para evaluar la asociación entre las variables se aplicó la prueba chi-cuadrado; el nivel de significación establecido fue de p<0,05. Resultados: La frecuencia de la erosión dental en los es- colares fue del 54,1%. Un 3,7% consumía bebidas refrescan- tes de 3 a 5 veces por semana, un 45,9% consumía 2 veces por semana, y el 50,4% no consumía o consumía menos de 2 ve- ces a la semana. Las gaseosas que más frecuentemente se con- sumían fueron la Coca-Cola (20,7%) y la Kola Real (20%). El 43,7% no ingería ningún tipo de bebida gaseosa. Se halló una asociación entre la erosión dental y la ingesta de bebidas refrescantes (chi-cuadrado 84,77, p<0,05), con una ingesta de 2 veces por semana o más (chi-cuadrado 62,589, p<0,05). La erosión dental fue más frecuente en aquellos alumnos que in- gerían ambas bebidas, gaseosas y rehidratantes en su dieta, comparado con solo gaseosas o rehidratantes (p=0,048). Conclusiones: Las bebidas refrescantes resultaron ser no- civas para la erosión dental, cuando estas bebidas se toman al menos dos veces por semana (AU)


Aim: Determine the relation between dental erosion and the consumption of the refreshing drinks in schoolchildren from 12 to 16 years of Juan Velasco Alvarado Educational Center, from Pillco Marca district, Peru. Materials and methods: An observational, cross-sec- tional study was carried out on a sample of 135 children from 12 to 16 years of age. From all the medical records avail- able, the final selection included the ones that had data on demographic variables, the assessment of the type of dental erosion according to the Eccles classification and that had answered the survey on the consumption of refreshing drinks (soft drinks, rehydrating drinks and juices). To evaluate the association between the variables, the chi-square test was ap- plied; the established significance level was p<0.05. Results: The frequency of dental erosion in schoolchil- dren was 54.1%. 3.7% consumed refreshing drinks 3 to 5 times a week, 45.9% consumed 2 times a week, and 50.4% did not consume or consumed less than 2 times a week. The soft drinks most frequently consumed were Coca-Cola (20.7%) and Kola Real (20%). 43.7% did not ingest any type of soft drink. An association was found between dental erosion and the intake of refreshing drinks (chi-square 84.77, p<0.05), with an intake of at least twice a week (chi-square 62.589, p<0.05). Dental erosion was more frequent in those students who ingested both soft drinks and rehydrating drinks in their diet, compared to only soft drinks or only rehydrating drinks (p=0.048 Conclusions: Refreshing drinks turned out to be harmful in relation to dental erosion, when these drinks are taken at least twice a week (AU)

RESUMO

Introducción. Los niños con trastorno del espectro autista (TEA) presentan dificultades de adaptación a situaciones estresantes, como la pandemia por COVID-19. Objetivo. Evaluar el impacto del primer año de pandemia en las dificultades alimentarias de niños con TEA. Población y métodos. Se invitó a participar a cuidadores de niños con TEA no sindromático (edad: 2-18 años) de una unidad de neurodesarrollo. Los participantes respondieron en línea un cuestionario y la escala de evaluación de problemas de conducta alimentaria (BPFAS por su sigla en inglés) antes y durante el primer año de pandemia. Se calculó un puntaje de prioridad (producto entre promedio de frecuencia y problema) para cada ítem del BPFAS. Resultados. El 56,6 % (86/152) de los cuidadores contestó la encuesta (madre 74,4 %), mediana de edad 6,3 años (p25-p75: 4,7-8,2); el 80,2 % de los niños eran de sexo masculino; el 58,1 % mantuvo terapia durante la pandemia y el 61,6 % presentaba problemas de comportamiento previo a esta. Durante el primer año de pandemia, los niños presentaron mayor intensidad en dificultades conductuales (34,9 %) y de alimentación (61,6 %); sin embargo, el 31,4 % refirió mejoría en la alimentación. No existieron diferencias significativas entre puntajes BPFAS antes y durante la pandemia. Los ítems con mayor puntaje de prioridad fueron "se levanta de la mesa durante la hora de comer", "no probar alimentos nuevos", "no come verduras", "no come frutas". Conclusiones. Hubo alta frecuencia de dificultades en las conductas alimentarias durante el primer año de pandemia. No se presentaron diferencias en las características de estas conductas antes y durante la pandemia.


Introduction. Children with autism spectrum disorder (ASD) have difficulties adapting to stressful situations, such as the COVID-19 pandemic. Objective. To assess the impact of the first year of the pandemic on feeding difficulties in children with ASD. Population and methods. The caregivers of children and adolescents with non-syndromic ASD (age: 2­18 years) from a neurodevelopment unit were invited to participate. Participants completed a questionnaire and the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) online before and during the first year of the pandemic. A priority score (product between the average frequency and the problem) for each BPFAS item was estimated. Results. Among the caregivers, 56.6% (86/152) completed the survey (mother: 74.4%); children's median age was 6.3 years (p25­p75: 4.7­8.2); 80.2% of children were males; 58.1% continued with their therapy during the pandemic; and 61.6% had behavioral problems before the pandemic. During the first year of the pandemic, children had greater behavioral problems (34.9%) and feeding difficulties (61.6%); however, 31.4% of caregivers referred improvements in feeding. There were no significant differences in the BPFAS scores before and during the pandemic. The following items obtained the highest priority scores: gets up from table during meal, does not try new food, does not eat vegetables, does not eat fruits. Conclusions. A high frequency of feeding difficulties was noted during the first year of the pandemic. No differences were observed in feeding characteristics before and during the pandemic.

RESUMO

Introducción: Una nutrición adecuada es clave para desarrollar inmunidad, protección contra las enfermedades e infecciones, y apoyar la recuperación. Objetivo: Identificar las características del consumo de alimentos y la cultura alimentaria en convalecientes de COVID-19. Métodos: Se realizó un estudio observacional, descriptivo y transversal, desde mayo hasta diciembre del 2020, de 67 pacientes mayores de 20 años de edad convalecientes de la COVID-19, con resultados negativos en la prueba de reacción en cadena de la polimerasa durante un mes, quienes pertenecían a un área de salud de La Habana. Se analizaron variables sociodemográficas, dietéticas y de estado nutricional. Resultados: La enfermedad se presentó con mayor frecuencia en el sexo masculino (59,7 %) y el grupo etario de 20 a 39 años (47,8 %). Se identificó un alto porcentaje de sobrepeso global (59,7) y los alimentos de mayor consumo y preferencia fueron los energéticos en el horario de la tarde-noche (89,6 %), así como aquellos productos fritos y la piel de aves (38,8 %). La ingestión de vegetales y frutas resultó escasa (29,9 y 40,3 %, respectivamente) y la alimentación, poco variada (86,4 %), pues no consumían diariamente alimentos de los 7 grupos básicos, aunque la mayoría (70,0 %) realizaba las 3 comidas principales del día. Conclusiones: Los sujetos estudiados poseían una cultura alimentaria deficiente expresada por conocimientos escasos o errados, lo que advierte sobre la necesidad de disponer de un instrumento educativo para la adopción de actitudes y prácticas alimentarias saludables que conduzcan a la restauración de la inmunidad.


Introduction: An appropriate nutrition is the key to develop immunity, protection against diseases and infections, and support the recovery. Objective: To identify the characteristics of foods consumption and alimentary culture in COVID-19 convalescent persons. Methods: An observational, descriptive and cross-sectional study was carried out, from May to December 2020, of 67 patients over 20 years convalescent from COVID-19, with negative results in the polymerase chain reaction test for a month, who belonged to a health area of Havana city. Some sociodemographic, dietary and nutritional state variables were analyzed. Results: The disease was presented more frequently in male sex (59.7%) and the 20 to 39 age group (47-8%). A high percentage of general overweight was identified (59.7), and the most consumed and preferred foods were the energy-giving in the afternoon-night time (89.6%), as well as those fried products and poultry skin (38.8%). The consumption of vegetables and fruits was low (29.9 and 40.3%, respectively) and there was a poor variety in the diet (86.4%), since they didn't consume foods from the 7 basic groups daily, although most of them (70.0%) had 3 meals a day. Conclusions: The studied individuals possessed a poor alimentary culture expressed by limited or wrong knowledge, what is a warning about the necessity of having an educational instrument for the adoption of attitudes and healthy alimentary habits leading to the restoration of immunity.

RESUMO

The present study aimed to evaluate and compare feeding responses of the non-native and native bivalves, the dark false mussel Mytilopsis leucophaeata and the scorched mussel Brachidontes darwinianus, respectively, by offering different concentrations of seston from the coastal lagoon where these species coexist after dark false mussel introduction (Rodrigo de Freitas Lagoon, Rio de Janeiro-Brazil). For this purpose, independent laboratory experiments were carried out under five concentrations of seston to test the differences in clearance and ingestion rates of bivalves as a function of increasing concentrations of suspended particulate matter (SPM) on seston. In addition, from the integrated analysis of data obtained in experiments, it can be inferred about the efficiency levels of these species to remove SPM from seston and their effects on water turbidity and nutrient concentrations (total carbon, nitrogen, and phosphorus). Our hypothesis was that the non-native bivalve is more efficient to clear and ingest SPM from seston compared to the native one, which may lead to competitive advantages to the successful invasion of M. leucophaeata in coastal lagoons. Native species did not show a significant difference in clearance and ingestion rates with increasing concentrations of seston. Whereas the non-native bivalve showed a slight tendency to increase its clearance and ingestion rates with the increase in seston concentrations, evidencing its plasticity to adjust its feeding responses. The native bivalve was significantly more efficient to clear and ingest SPM at the lower seston concentration (i.e., close to natural concentrations found in the lagoon) compared to the non-native bivalve, which, on the other hand, showed a significant increase in its ingestion rates at the higher concentration tested (140 mg SPM L-1). Thus, the present results did not suggest food competition between the non-native M. leucophaeata and the native B. darwinianus in the introduced system. However, M. leucophaeata increased its feeding response with experimental increment in seston concentration, which suggests species ability to benefit from conditions of increased inputs of organic matter and higher primary production that could mediate its establishment in introduced systems.

RESUMO

Human settlements within the Antarctic continent have caused significant coastal pollution by littering plastic. The present study assessed the potential presence of microplastics in the gastrointestinal tract of the Antarctic fish Harpagifer antarcticus, endemic to the polar region, and in the sub-Antarctic fish Harpagifer bispinis. H. antarcticus. A total of 358 microfibers of multiple colors were found in 89 % of H. antarcticus and 73 % of H. bispinis gastrointestinal track. A Micro-FTIR analysis characterized a sub-group (n = 42) of microfibers. It revealed that most of the fibers were cellulose (69 %). Manmade fibers such as microplastics polyethylene terephtalate, acrylics, and semisynthetic/natural cellulosic fibers were present in the fish samples. All the microfibers extracted were textile fibers of blue, black, red, green, and violet color. Our results suggest that laundry greywater discharges of human settlements near coastal waters in Antarctica are a major source of these pollutants in the Antarctic fish.

RESUMO

The ubiquity of microplastics has caused alarm as to the impact of these materials on aquatic life, leading to experimental studies to understand these effects. In zooplankton bioassays, microspheres (Ms) are often used as a proxy to represent aquatic microplastic contamination due to their homogeneity and small sizes (<100 µm). The present study proposes an accessible protocol that does not require highly specialized equipment for the creation of Ms stock solutions and environmentally realistic experimental concentrations and describes some common issues. Adult females of the calanoid copepod Centropages furcatus underwent treatments of two Ms sizes at experimental concentrations of 10 Ms/mL. They consumed on average 0.9 ± 2.6 Ms/mL of 45-53 µm Ms, and 2.4 ± 1.1 Ms/mL of 38-45 µm Ms. The results are not directly comparable with other studies due to the wide variety of methods used but successfully demonstrate the reproducibility of the proposed protocol.

RESUMO

A alimentação tem efeitos diretos na saúde do binômio mãe-filho, bem como nos desfechos da gravidez, o que torna necessária a análise do consumo alimentar durante a gestação, principalmente considerando as mudanças nos hábitos alimentares ocorridas nas últimas décadas. O objetivo deste estudo foi analisar o consumo alimentar de gestantes atendidas pela Estratégia Saúde da Família, segundo o grau de processamento e a adequação de macro e micronutrientes. Trata-se de um estudo de corte transversal realizado com 239 gestantes atendidas pela Estratégia Saúde da Família durante o pré-natal. A análise do consumo alimentar foi feita utilizando o questionário de frequência alimentar reduzido, considerando a classificação NOVA. Foram calculados média e desvio padrão, com intervalo de confiança de 95%, porcentagem de contribuição de energia, macro e micronutrientes e adequação aos níveis de consumo recomendados. A maior contribuição energética e de nutrientes derivou de alimentos processados (59%), a maioria das gestantes apresentou elevado consumo de sódio (76,15%), e a contribuição de energia proveniente de alimentos in natura ou minimamente processados (20,3%) e ultraprocessados (20,1%) alcançou valores aproximados. O consumo de proteínas (86,19%), carboidratos (91,63%), fibras (71,55%), sódio (76,15%), zinco (58,16%), magnésio (64,44%), vitaminas A (80,75%), D (52,3%), B12 (69,87%), B9 (51,46%) e C (95,82%) foi acima do recomendado. Houve maior prevalência de consumo de alimentos processados, embora a ingestão de alimentos in natura ou minimamente processados e ultraprocessados tenha atingido níveis aproximados. O consumo de macronutrientes foi inadequado, assim como da maioria dos micronutrientes, segundo as recomendações para gestantes.


Eating has direct effects on the health of the mother-child binomial, as well as on pregnancy outcomes, which makes it necessary to analyze food intake during pregnancy, especially considering the changes in eating habits that have occurred in recent decades. This study aimed to analyze the food intake of pregnant women assisted by the Family Health Strategy according to the degree of processing and the adequacy of macronutrients and micronutrients. This is a cross-sectional study conducted with 239 pregnant women assisted by the Family Health Strategy during prenatal care. The food consumption analysis was done using the reduced food frequency questionnaire, considering the NOVA classification. Mean and standard deviation, with 95% confidence interval, percentage of energy, macronutrients and micronutrients contribution, and adequacy to the recommended consumption levels were calculated. The highest energy and nutrient contribution was derived from processed foods (59%), most pregnant women presented high sodium intake (76.15%), and the energy contribution from in natura or minimally processed (20.3%) and ultra-processed (20.1%) foods reached approximate values. The consumption of proteins (86.19%), carbohydrates (91.63%), fibers (71.55%), sodium (76.15%), zinc (58.16%), magnesium (64.44%), vitamins A (80.75%), D (52.3%), B12 (69.87%), B9 (51.46%), and C (95.82%) was above the recommendations. Higher prevalence of consumption of processed foods was observed, despite the ingestion of in natura or minimally processed and ultraprocessed foods reaching approximate levels. The consumption of macronutrients was inadequate, as well as most micronutrients, according to the recommendations for pregnant women.


La alimentación tiene efectos directos sobre la salud del binomio madre-hijo, así como sobre los resultados del embarazo, lo que hace necesario analizar el consumo de alimentos durante el embarazo, principalmente por los cambios en los hábitos alimentarios ocurridos en las últimas décadas. El objetivo de este estudio es analizar el consumo de alimentos por las mujeres embarazadas atendidas en la Estrategia Salud Familiar según el grado de elaboración y adecuación de macronutrientes y de micronutrientes. Este es un estudio transversal, realizado con 239 mujeres embarazadas atendidas por la Estrategia Salud Familiar durante el prenatal. El análisis del consumo de alimentos se realizó mediante un cuestionario de frecuencia alimentaria reducida, considerando la clasificación NOVA. Se calcularon la media y la desviación estándar con un intervalo de confianza del 95%, el aporte porcentual de energía, macronutrientes y micronutrientes y la adecuación a los niveles de ingesta recomendados. El mayor aporte de energía y de nutrientes se derivó de los alimentos procesados (59%), la mayoría de las embarazadas presentaron alto consumo de sodio (76,15), y el aporte de energía de los alimentos in natura o mínimamente procesados (20,3%) y ultraprocesados (20,1%) alcanzó valores aproximados. El consumo de proteínas (86,19%), carbohidratos (91,63%), fibras (71,55%), sodio (76,15%), zinc (58,16%), magnesio (64,44%), vitaminas A (80,75%), D (52,3%), B12 (69,87%), B9 (51,46%) y C (95,82%) estuvo por encima de las recomendaciones. Hubo una mayor prevalencia de consumo de alimentos procesados, aunque la ingesta de alimentos in natura o mínimamente procesados y ultraprocesados alcanzaron niveles aproximados. El consumo de macronutrientes resultó ser inadecuado, así como la mayoría de los micronutrientes recomendados para embarazadas.
