Abstract Continuous illumination and increased feeding periods have enhanced growth in commercial fish species. However, oxygen consumption under these conditions has yet to be previously assessed in agastric short-intestine fish. This study evaluated Chirostoma estor (Atherinopsidae) oxygen consumption under three specific feeding and light regimes: resting-unfed, routine-fed, and continuous light/feeding. Fish in the continuous light/feeding condition presented oxygen consumption levels 60 and 20% higher than resting-unfed and routine-fed fish, respectively. The latter implies that constant high oxygen supply levels are required to satisfy the demand for C. estor raised under these high growth rate conditions. The present study shows the relevance of determining oxygen consumption levels during continuous illumination and extended feeding periods to consider optimal oxygen levels required to achieve better performance indicators, such as the growth and welfare of atherinopsids and species with similar digestive configurations.

Resumen La iluminación continua y el aumento de frecuencias alimenticias han mejorado el crecimiento de peces en cultivo. Sin embargo, el consumo de oxígeno en estas condiciones no se ha evaluado en peces agástricos de intestino corto. Este estudio evaluó el consumo de oxígeno de Chirostoma estor bajo tres regímenes específicos de alimentación y luz: reposo sin alimentación, alimentación de rutina y alimentación/luz continua. En este último tratamiento los peces presentaron niveles de consumo de oxígeno de 60 y 20% más altos que los peces en reposo y con alimentación rutinaria, respectivamente. Esto implica que se requieren niveles elevados y constantes de suministro de oxígeno para satisfacer la demanda de C. estor en cultivo en condiciones crecimiento acelerado. El presente estudio muestra la relevancia de determinar los niveles de consumo de oxígeno bajo protocolos de crecimiento acelerado para lograr mejores indicadores de desempeño de otras especies con configuraciones digestivas similares.

ABSTRACT In Brazil, the COVID-19 burden was substantial, and risk factors associated with higher in-hospital mortality rates have been extensively studied. However, information on short-term all-cause mortality and the factors associated with death in patients who survived the hospitalization period of acute SARS-CoV-2 infection is limited. We analyzed the six-month post-hospitalization mortality rate and possible risk factors of COVID-19 patients in a single center in Brazil. This is a retrospective cohort study focused on a six-month follow-up. The exclusion criteria were death during hospitalization, transference to another hospital, and age under 18. We collected data from the charts of all hospitalized patients from March 2020 to December 2020 with a positive RT-PCR test for SARS-CoV-2, resulting in a sample size of 106 patients. The main outcome was death after hospitalization, whereas comorbidities and demographics were evaluated as risk factors. The crude post-hospitalization death rate was 16%. The first 30 days of follow-up had the highest mortality rate. In a Cox regression model for post-hospitalization mortality, previous chronic kidney disease (HR, 4.06, 95%CI 1.46 – 11.30) and longer hospital stay (HR 1.01, 95%CI 1.00 – 1.02) were the only factors statistically associated with death. In conclusion, a high six-month all-cause mortality was observed. Within the six-month follow-up, a higher risk of death was observed for patients who had prior CKD and longer hospital stay. These findings highlight the importance of more intensive medical surveillance during this period.

ABSTRACT Despite being subject to lower AIDS-related mortality rates and having a higher life expectancy, patients with HIV are more prone to develop non-AIDS events. A low CD4+/CD8+ ratio during antiretroviral therapy identifies people with heightened immune senescence and increased risk of mortality. In clinical practice, finding determinants of a low CD4+/CD8+ ratio may be useful for identifying patients who require close monitoring due to an increased risk of comorbidities and death. We performed a prospective study on the evolution of the CD4+/CD8+ ratio in 60 patients infected with HIV (80% males), who were subjected to two different antiretroviral regimens: early and deferred therapy. The initial CD4+/CD8+ ratio was ≤1 for 70% of the patients in both groups. Older age, CD4+ cell count at inclusion, Nadir CD8+T-cell count, and Initial CD4+/CD8+ ratio ≤ 1 were risk factors for lack of ratio recovery. In the multivariate analysis, a CD4+/CD8+ ratio > 1 at the start of the treatment was found to be a determinant factor in maintaining a CD4+/CD8+ ratio > 1. The nadir CD4+T-cell count was lower in the deferred therapy group (p=0.004), and the last CD4+/CD8+ ratio ≤1 was not associated with comorbidities. Ratio recovery was not associated with the duration of HIV infection, time without therapy, or absence of AIDS incidence. A greater improvement was observed in patients treated early (p=0.003). In contrast, the slope of increase was slower in patients who deferred treatment. In conclusion, the increase in the CD4+/CD8+ ratio occurred mostly for patients undergoing early strategy treatment and its extension did not seem to be related to previous HIV-related factors.

ABSTRACT Objetives: The incidence of posttransplant diabetes and the elevated cardiovascular (CV) risk among transplant recipients are on the rise. Glucagon-like peptide agonists have the potential to mitigate the effects of immunosuppressive drugs, addressing both hyperglycemia and weight gain. This makes them appealing for use in this population, given their CV and renoprotective benefits. Nevertheless, there is insufficient substantial evidence regarding their efficacy in diabetic kidney transplant recipients (KTR). Methods: The objective of this retrospective study was to assess the effectiveness and safety of glucagon-like peptide agonists in KTR. The primary focus was to evaluate their impact on various parameters, such as hemoglobin A1c levels, body mass index (BMI), lipid panel, hemoglobin levels, renal allograft function (estimated glomerular filtration rate [eGFR]), and urinary protein-to-creatinine ratio. Results: During a median observation period of 18 months, this investigation included 64 renal transplant patients. Median eGFR at baseline was 61.9 mL/min/1.73 m2 and remained stable throughout the follow-up. Median HbA1cdecreased from 7.5 to 7% (95%CI; p < 0.002). A significant improvement in BMI and lipid panel were also observed. We did not observed significant changes regarding median creatinine and urinary protein:creatinine ratio levels. No side effects justified discontinuation of the drug. Conclusion: This study shows that the use of glucagon-like peptide agonists is feasible and well-tolerated in KTR, with no significant side effects observed. Subsequent studies are needed to explore whether glucagon-like peptide agonists can effectively improve allograft survival in these patients.

RESUMO Objetivos: A incidência de diabetes pós-transplante e o aumento do risco cardiovascular entre os receptores de transplante estão em ascensão. Os agonistas do receptor de peptídeo semelhante ao glucagon têm o potencial de mitigar os efeitos dos medicamentos imunossupressores, abordando tanto a hiperglicemia quanto o aumento de peso, o que os torna atrativos para uso nesta população, dadas as suas vantagens cardiovasculares e renoprotetoras. No entanto, a evidência atual é insuficiente sobre a sua eficácia em receptores de transplante renal diabéticos (RTRD). Métodos: O objetivo deste estudo retrospectivo foi avaliar a eficácia e segurança dos agonistas do peptídeo semelhante ao glucagon-1 em RTRD. O foco principal foi avaliar o seu impacto em vários parâmetros, tais como níveis de hemoglobina A1c, índice de massa corporal (IMC), perfil lipídico, níveis de hemoglobina, função do enxerto renal (taxa de filtração glomerular estimada [TFGe]) e relação proteína-creatinina urinária. Resultados: Durante um período de observação mediano de 18 meses, esta investigação incluiu 64 pacientes transplantados renais. A TFGe mediana no início foi de 61,9 mL/min/1,73 m2 e permaneceu estável durante o acompanhamento. A mediana da HbA1c diminuiu de 7,5 para 7% (IC95%; p < 0,002). Também foi observada uma melhoria significativa no IMC e no perfil lipídico. Não foram observadas mudanças significativas nos níveis medianos de creatinina e relação proteína:creatinina urinária. Nenhum efeito colateral justificou a descontinuação do medicamento. Conclusão: Este estudo mostra que o uso de agonistas do peptídeo semelhante ao glucagon é viável e bem tolerado em RTRD, sem efeitos colaterais significativos observados. Estudos subsequentes são necessários para explorar se esta terapêutica pode melhorar efetivamente a sobrevida do aloenxerto nesses pacientes.

ABSTRACT Introduction: Considering the rising occurrence of posttranplant diabetes and the elevated cardiovascular burden among transplant recipients, the utilization of SGLT2 inhibitors (SGLT2i) in this group is appealing because of their cardiovascular and renoprotective benefits. Nevertheless, there is a scarcity of evidence for diabetic kidney transplant recipients (DKTRs) owing to concerns about potential renal graft damage and adverse effects. Methods: This retrospective study was devised to assess the effectiveness and safety of SGLT2i in kidney transplant recipients (KTRs). The main focus was on evaluating their impact on parameters such as haemoglobin A1c levels, body mass index (BMI), lipid panel, haemoglobin levels, renal allograft function (estimated glomerular filtration rate) and urirnary protein-to-creatinine ratio. Results: A total of 75 renal transplant patients were included in this investigation. The study spanned a median observation period of 18 (2.0–71.0) months. Median estimated glomerular filtration rate at baseline was 61,9 (26–120) mL/min/1.73 m2 and remained stable throughout the follow-up. Median HbA1cdecreased from 7.5 to 7.0% (95% CI; p<0,002). A significant improvement in BMI (95% CI; p<0,001) and lipid panel (95% CI; p<0,05) were also observed. Median haemoglobin rate at baseline was 13,5g/dL and modestly improved at end of follow-up to 13,7g/dL (p=0,12). Regarding urinary protein:creatinine ratio, levels slightly but not significantly rose [+0.05 g/g (p=0,9)]. In a post-hoc subgroup analysis, the rate of urinary tract infections was low (10%). No other side effects were observed during the treatment course. Conclusions: This study demonstrates that the administration of SGLT2i is viable and well-tolerated, with no notable side effects observed in KTRs. However, the question of whether SGLT2i can effectively lower cardiovascular mortality and enhance allograft survival in these patients remains to be explored in subsequent studies.

RESUMO Introdução: Considerando o aumento da incidência de diabetes pós-transplante e o elevado impacto cardiovascular entre os receptores de transplantes, este facto faz com que o uso de inibidores de SGLT2 nesse grupo seja atrativo devido aos seus benefícios cardiovasculares e renoprotetores. No entanto, há escassez de evidência nos receptores de transplante renal com diabetes devido a preocupações com possíveis danos ao enxerto renal e efeitos adversos. Métodos: Este estudo retrospectivo foi elaborado para avaliar a eficácia e segurança dos inibidores de SGLT2 em receptores de transplante renal (KTRs). O foco principal foi avaliar o seu impacto em parâmetros como níveis de hemoglobina A1c, índice de massa corporal (IMC), perfil lipídico, níveis de hemoglobina, função do enxerto renal (taxa de filtração glomerular estimada) e relação proteína/creatinina urinária. Resultados: Um total de 75 pacientes receptores de transplante renal foram incluídos em nossa investigação. O estudo abrangeu um período de observação mediano de 18 (2,0–71,0) meses. A taxa média de filtração glomerular estimada no início foi de 61,9 (26–120) mL/min/1,73 m2 e permaneceu estável durante o acompanhamento. A mediana da HbA1c diminuiu de 7,5 para 7,0% (IC 95%; p<0,002). A melhora significativa no IMC (IC 95%; p<0,001) e no perfil lipídico (IC 95%; p<0,05) também foram observados. A taxa média de hemoglobina no início foi de 13,5g/dL e melhorou modestamente no final do acompanhamento para 13,7g/dL (p=0,12). Em relação à relação proteína/creatinina urinária, os níveis aumentaram ligeiramente, mas não significativamente [+0,05 g/g (p=0,9)]. Numa análise de subgrupo post-hoc, a taxa de infecções do trato urinário foi baixa (10%). Nenhum outro efeito colateral foi observado durante o curso do tratamento. Conclusões: Este estudo demonstra que a administração de inibidores de SGLT2 é viável e bem tolerada, sem efeitos colaterais notáveis em receptores de transplante renal. No entanto, a questão de saber se a inibição do SGLT2 pode efetivamente reduzir a mortalidade cardiovascular e melhorar a sobrevida do enxerto nesses pacientes permanece a ser explorada em estudos subsequentes.

ABSTRACT The presence of genetic mutations in HIV poses a significant challenge, potentially leading to antiretroviral resistance and hampering therapeutic development. The Brazilian population has presented variations in the HIV envelope V3 loop gene, especially the GWGR motif. This motif has been linked to reduced transmission potential and slower CD4+ T cell decline. This study aimed to assess clinical outcomes in patients with HIV-1 infected with strains containing the GWGR motif compared with those without it during long-term cART. A cohort of 295 patients with HIV was examined for the GWGR motif presence in the V3 loop. A total of 58 samples showed the GWGR signature, while 237 had other signatures. Multifactorial analyses showed no significant differences in demographic characteristics, CD4+ cell count, AIDS progression, or mortality between GWGR carriers and others. However, the mean interval between the first positive HIV test and the initial AIDS-defining event was more than two times longer for women carrying the GWGR signature (p = 0.0231). We emphasize the positive impact of cART on HIV/AIDS treatment, including viral suppression, CD4+ cell preservation, and immune function maintenance. Although no significant differences were found during cART, residual outcomes reflecting adherence challenges were observed between diagnosis and the first AIDS-defining event. The previously described outcomes, highlighting statistically significant differences between individuals carrying the GPGR motif compared with those with the Brazilian GWGR motif, may be directly linked to the natural progression of infection before advancements in cART. Presently, these physicochemical aspects may no longer hold the same relevance. challenge development V gene CD4 CD decline HIV1 1 HIV- longterm long term 29 5 23 signatures characteristics count others However AIDSdefining defining p 0.0231. 00231 0.0231 . 0 0231 0.0231) HIVAIDS treatment suppression preservation maintenance Presently relevance 2 0023 0.023 023 002 0.02 02 00 0.0 0.

Resumo Objetivo Neste estudo, investigamos o impacto de uma intrusão marinha nas características da coluna d'água da lagoa de Jurubatiba, um ecossistema costeiro tropical, por 12 meses após um evento de abertura da barra de areia, a fim de elucidar a duração de seus efeitos na lagoa. Métodos Amostramos mensalmente as características físicas, químicas e biológicas ao longo do perfil vertical da coluna d'água após a abertura da barra de areia e entrada de água do mar. Avaliamos a associação temporal (mensalmente) e espacial (ao longo do perfil de profundidade) entre essas variáveis e a correlação temporal na heterogeneidade vertical dessas variáveis e condições ambientais que promovem a estratificação. Resultados A intrusão marinha resultou na formação de cunhas salinas em curto prazo, levando à estratificação na concentração de oxigênio dissolvido, pH, salinidade e clorofila-a ao longo da coluna de água por, pelo menos, quatro meses. No entanto, a temperatura atmosférica e a incidência solar também emergiram como fatores cruciais associados à heterogeneidade vertical nas variáveis limnológicas, influenciando a densidade da água e o pH ao longo do período de estudo. A precipitação e a velocidade do vento tiveram apenas efeitos marginais nas variações térmicas e ectogênicas, provavelmente mediadas pela cor da água, entrada de nutrientes, profundidade da coluna d'água e orientação da lagoa na paisagem. Conclusões Apesar de rasas e expostas a ação dos ventos, as lagoas costeiras podem apresentar uma considerável heterogeneidade vertical nas condições limnológicas devido a vários fatores climáticos e hidrodinâmicos. Notavelmente, os efeitos de intrusões marinhas na salinidade e na estratificação da coluna d'água podem persistir por vários meses, afetando a qualidade da água e, provavelmente, as comunidades bióticas e o funcionamento do ecossistema. Uma vez que as atividades humanas e as mudanças climáticas podem intensificar as intrusões marinhas em lagoas costeiras, compreender seus efeitos na dinâmica limnológica é fundamental para nossa capacidade de prevê-los e conservar ecossistemas tão vulneráveis. estudo dágua d Jurubatiba tropical 1 físicas mar (mensalmente prazo dissolvido clorofilaa clorofila menos entanto ectogênicas nutrientes paisagem ventos hidrodinâmicos Notavelmente prevêlos prevê los vulneráveis

Abstract Aim In this study, we investigated the impact of an episodic marine intrusion on the water column characteristics of Jurubatiba lagoon, a tropical coastal ecosystem, for 12 months following a sandbar breaching event to elucidate the duration of its effects. Methods Monthly, we sampled the physical, chemical, and biological characteristics along the water column for one year after a sandbar breaching event and seawater inflow. We assessed the temporal (monthly) and spatial (along depth profiles) associations among these variables and the temporal correlation among vertical heterogeneities in these variables and environmental drivers of stratification. Results Marine intrusion resulted in salt wedges formation in the short-term, leading to stratification in dissolved oxygen, pH, salinity, and chlorophyll-a concentration along the water column for at least four months. However, temperature and solar incidence also emerged as crucial factors associated with vertical heterogeneity in limnological variables, influencing water density and pH throughout the study period. Precipitation and wind speed had only marginal effects on thermal and ectogenic stratifications, probably mediated by water colour, nutrient inputs, water column depth and lagoon’s orientation in the landscape. Conclusions Our data unveiled that, despite their shallowness and wind exposure, coastal lagoons can exhibit considerable vertical heterogeneities in limnological variables due to various climatic and hydrodynamic aspects. Notably, the effects of marine intrusions on salinity and ectogenic column stratification can persist for several months, affecting water quality and, probably, biotic communities and ecosystem functioning. Once human activities and climate change may intensify marine intrusions on coastal lagoons, understanding spatiotemporal dynamics and their drivers is fundamental to anticipating their effects and conserving such vulnerable ecosystems. lagoon 1 Monthly physical chemical inflow monthly (monthly profiles shortterm, shortterm short term, term short-term oxygen chlorophylla chlorophyll However period stratifications colour inputs s landscape that exposure aspects Notably functioning ecosystems

Resumen: La diabetes mellitus, un padecimiento crónico y progresivo, ocupó el tercer lugar en defunciones durante el período comprendido de enero a junio de 2021 en México. Su complicación crónica más frecuente es la neuropatía diabética que tiene un impacto importante en el sistema nervioso. En la Ciudad de México se reunió un grupo multidisciplinario de expertos para establecer un algoritmo de tratamiento que considere los aspectos sintomáticos y etiopatogénicos de la neuropatía diabética. Se utilizó un método Delphi en tiempo real con dos rondas de preguntas interactivas. La implementación del algoritmo propuesto permitirá abordar de manera integral al paciente diabético con neuropatía dolorosa y no dolorosa, tanto en el terreno de los síntomas como en la etiopatogenia. Este abordaje brinda la oportunidad de mejorar la calidad de vida y lograr la reinserción a la vida familiar y laboral. El panel de expertos recomienda al ácido tióctico como tratamiento etiopatogénico de primera línea en la neuropatía diabética.

Abstract: Diabetes mellitus, a chronic and progressive condition, was the third most common cause of death in Mexico between January and June 2021. Its most frequent chronic complication is diabetic neuropathy, which has a major impact on the nervous system. A multidisciplinary group of experts met in Mexico City to establish a treatment algorithm considering the symptomatic and etiopathogenic aspects of diabetic neuropathy. A real-time Delphi method with two rounds of interative questions was used. The implementation of the proposed algorithm will allow a comprehensive approach to the diabetic patient with painful and non-painful neuropathy, both in terms of symptoms and etiopathogenesis. This approach provides the opportunity to improve quality of life and achieve reintegration into family and work life. The expert panel recommends thioctic acid as the first line etiopathogenic treatment for diabetic neuropathy.

Abstract Introduction: This study aimed to assess the clinical, economic, and humanistic impact of short-bowel syndrome/chronic intestinal failure (SBS/CIF) in Portugal. Methods: This is a retrospective multicenter cohort chart review study, with a cross-sectional component for quality-of-life (QoL) evaluation. Inclusion criteria comprised patients with SBS/CIF, aged ≥1 year, with stable parenteral nutrition (PN). Data collection included patient chart review over a 12-month period and patient/caregiver self-report and SF-36/PedsQL™ questionnaires. Main endpoints comprised clinical and PN characterization, healthcare resource use (HRU), direct costs, and patient QoL. Results: Thirty-one patients were included (11 adults and 20 children). Patients’ mean age (standard deviation [SD]) was 57.9 (14.3) years in adults and 7.5 (5.0) years in children, with a mean time since diagnosis of 10.2 (5.9) and 6.6 (4.2) years, respectively. PN was administered for a mean of 5.2 and 6.6 days/week in adults and children, respectively; home PN occurred in 81.8% of adults and 90.0% of children for a mean of 9.6 and 10.8 months/year, respectively. The mean annual number of hospitalizations was 1.9 and 2.0 which lasted for a mean of 34.0 and 29.4 days in adults and children, respectively. Twenty-one and forty hospitalization episodes were reported in adults and children, respectively, of which 71.4% and 85.0% were due to catheter-related complications. Mean annual direct costs per patient amounted to 47,857.53 EUR in adults and 74,734.50 EUR in children, with PN and hospitalizations as the main cost-drivers. QoL assessment showed a clinically significant impaired physical component in adults and a notable deterioration in the school functioning domain in children. Conclusion: In Portugal, SBS/CIF patient management is characterized by a substantial therapeutic burden and HRU, translating into high direct costs and a substantial impairment of the adults’ physical function and children’s school functioning.

Resumo Introdução: Este estudo teve como objetivo avaliar o impacto clínico, económico e social da síndrome do intestino curto/falência intestinal crónica (SIC/FIC) em Portugal. Métodos: Estudo de coorte retrospectivo e multicêntrico de revisão dos processos clínicos incluindo uma componente transversal para avaliação da qualidade de vida (QV). Os critérios de elegibilidade incluíram doentes com SIC/FIC, idade ≥1 ano, em nutrição parenteral (NP) e clinicamente estáveis.

Os indicadores principais foram a caracterização clínica e da NP, a utilização de recursos de saúde, custos diretos e QV dos doentes. Resultados: Foram incluídos 31 doentes (11 adultos e 20 crianças). A idade média (desvio padrão: DP) foi de 57.9 (14.3) anos nos adultos e de 7.5 (5.0) nas crianças com um tempo médio desde o diagnóstico de 10.2 (5.9) e 6.6 (4.2) anos, respetivamente. A NP foi administrada durante uma média de 5.2 e 6.6 dias por semana, em adultos e crianças respetivamente, em 81.8% e 90.0% dos adultos/crianças foi feita em casa durante uma média de 9.6 ou 10.8 meses por ano, respetivamente. O número médio anual de hospitalizações foi de 1.9 (1.6) e 2.0 (1.5) com uma duração média de 34.0 (47.4) e 29.4 (32.3) dias, em adultos e crianças, respetivamente. Foram reportados 21 e 40 episódios de hospitalização em adultos/crianças, dos quais 71.4% e 85.0% foram devido a complicações relacionadas ao uso de cateter. Os custos diretos anuais médios por doente ascenderam a 47,857.53 EUR nos adultos e a 74,734.50 EUR nas crianças, sendo que os maiores responsáveis foram a NP e as hospitalizações. A avaliação da QV mostrou um comprometimento clinicamente significativo da componente física nos adultos e uma deterioração relevante da dimensão escolar nas crianças. Conclusões: A gestão dos doentes com SIC/FIC em Portugal é caracterizada por uma sobrecarga substancial a nível terapêutico e de utilização de recursos de saúde, o que se traduz em elevados custos diretos e comprometimento substancial da componente física nos adultos e do desempenho escolar nas crianças.

Resumo Introdução: A deiscência anastomótica (DA) é uma complicação grave no pós-operatório precoce da esofagectomia e gastrectomia total, pela sua elevada mortalidade. As próteses metálicas autoexpansíveis (PMAE) desempenham um papel fundamental no tratamento das DA. Na literatura, há apenas um caso descrito sobre a utilização de um Mega-Stent no contexto de DA, que não complicação bariátrica. Os autores reportam uma série de dois casos com diferente aplicação do Mega-Stent esofágico no tratamento de DA. Descrição do caso: Caso 1: Homem de 67 anos, submetido a esofagectomia por carcinoma epidermóide do esófago distal. O período pós-operatório precoce foi complicado de DA com fístula gastro-pleural. Inicialmente foi colocado um clip OTSC no orifício da deiscência com insucesso técnico e clínico, sendo posteriormente utilizado o Mega-Stent, posicionado desde o esófago até ao bulbo duodenal. Estudos contrastados posteriores confirmaram resolução da DA. Caso 2: Mulher de 86 anos, submetida a gastrectomia total com reconstrução em Y-Roux e esofagojejunostomia por adenocarcinoma gástrico, complicada de DA. Neste contexto foi colocada uma PMAE parcialmente coberta (PMAE-PC) sobre a área da anastomose. A tomografia computorizada subsequente demonstrou persistência de extravasamento. Foi colocada uma segunda PMAE-PC, com posterior resolução da DA. Semanas depois, ambas as PMAE-PC apresentavam tecido de granulação nos topos, tendo sido colocado o Mega-Stent (técnica stent-in-stent) e decorridas duas semanas, todas as próteses foram facilmente extraídas, confirmando-se sucesso no tratamento da DA. Discussão/conclusão: A utilização de PMAE nas DA constitui uma técnica terapêutica segura e bem estabelecida, contudo passível de apresentar limitações tais como a migração ou incapacidade de cobrir totalmente DA de maiores dimensões. O Mega-Stent esofágico pode constituir uma ferramenta útil na terapêutica endoscópica destes doentes.

Abstract Introduction: Anastomotic leak (AL) is a dangerous complication in the early postoperative period after total gastrectomy or esophagectomy being associated with high mortality. Self-expandable metal stents (SEMS) play a significant role in AL management. Only one case report described the use of Mega-Stent in AL setting. The authors report a two-case series with different applications of a Niti-S esophageal Mega-Stent in AL management. Case Report: Case 1 is a 67-year-old male who underwent an esophagectomy due to a squamous cell carcinoma of the distal esophagus. The early postoperative period was complicated with AL and gastropleural fistula. Initially, an OTSC was deployed in the dehiscence but failed to resolve AL. The esophageal Mega-Stent was further placed in-between the esophagus and the bulbus. Post-stenting contrast studies confirmed no further AL. Case 2 is an 86-year-old woman who underwent total gastrectomy with roux-en-y esophagojejunostomy due to a gastric adenocarcinoma, complicated with AL. A partially covered metal stent (PCMS) was placed to cover the anastomosis. Computed tomography confirmed leakage persistence and a second PCMS was deployed, resolving the AL. Several weeks later, both PCMSs presented ingrowth from granulation tissue. An esophageal Mega-Stent was placed (stent-in-stent technique) and 2 weeks later, all stents were removed, with no AL recurrence. Discussion/Conclusion: SEMS placement for AL is a safe, well-established therapeutic technique. Limitations include stent migration and incomplete cover of large AL. Mega-Stent can be an emerging tool for endoscopic AL management.

Hematological problems are associated with Coronavirus disease 2019 (COVID-19). Respiratory impairment is the higher point studied, although without experimental studies related to the oxygen transport performed by erythrocytes. Therefore, we decided to investigate if erythrocytes from COVID-19 patients have their functionality changed. The case-control study included hospitalized patients with a positive real-time polymerase chain reaction (RT-PCR) result admitted to University Hospital. Volunteers (negative RT-PCR results) were recruited as a control group. Thus, we assessed different erythrocytes parameters, oxidative stress markers, and biophysical studies using whole blood and isolated hemoglobin. We found a decrease of 51% in oxygen uptake and reduced antioxidant enzyme activity in COVID-19 patients compared to controls. Raman spectrometry showed structural changes in the hemoglobin and lipids of the erythrocytes from COVID-19 patients; thus, these results were consolidated with an increase in Young’s modulus in erythrocytes followed by morphology changes. Besides, isolated hemoglobin from COVID-19 patients has a distinct interaction profile using a ligand model compared to the control. COVID-19 leads to structural, functional, and morphological damage to human erythrocytes. Our data showed structural and molecular changes and induction of oxidative stress in erythrocytes by COVID-19, a new perspective on the contribution of erythrocytes to a respiratory commitment in COVID-19. 201 COVID19.

ABSTRACT The covid-19 vaccine confers direct protection and reduces transmission rates of the virus and new variants. Vaccines from Pfizer/BioNTech and CoronaVac have been cleared for children in Brazil. They are safe, effective, and immunogenic. There are no known complications associated with the use of steroids or vaccines in pediatric patients with covid-19 and nephrotic syndrome. With or without immunosuppression, these patients are not at increased risk of severe covid-19, and steroids are safe for them. A milder form of covid-19 occurs in patients with chronic kidney disease without the need for hospitalization. The vaccine response may be reduced and/or the duration of antibodies after vaccination may be shorter than in the general population. However, considering risk of exposure, vaccination against covid-19 is recommended. It is believed that patients with hemolytic-uremic syndrome are at higher risk of severe covid-19. Vaccination is recommended, although specific data on the safety and efficacy of the covid-19 vaccine are limited. There is agreement that the benefits of induced immunity outweigh the risks of immunization. Vaccination against covid-19 is recommended for children and adolescents needing kidney transplantation or who have undergone transplantation. These patients present decreased immune response after vaccination, but immunization is recommended because the benefits outweigh the risks of vaccination. Current recommendations in Brazil stipulate the use of the messenger RNA vaccine. This paper aims to provide pediatric nephrologists with the latest knowledge about vaccination against covid-19 for children with kidney disease. covid19 covid 19 covid-1 variants PfizerBioNTech Pfizer BioNTech effective immunogenic immunosuppression covid19, 19, them hospitalization andor population However exposure hemolyticuremic hemolytic uremic covid19. 19. limited covid1 1 covid-

Resumo A vacina covid-19 confere proteção direta, reduz as taxas de transmissão do vírus e de novas variantes. No Brasil, estão liberadas para a população pediátrica as vacinas Pfizer/BioNTech e a CoronaVac, ambas seguras, eficazes e imunogênicas. Pacientes pediátricos com síndrome nefrótica e covid-19 têm curso clínico regular sem complicações relacionadas ao uso de esteroides ou vacinas. Esses pacientes, com ou sem imunossupressão, não apresentam maior risco de covid-19 grave e o tratamento com esteroides é seguro. Os pacientes com doença renal crônica têm covid-19 mais leve, sem necessidade de hospitalização. A resposta vacinal pode ser reduzida e/ou a duração dos anticorpos pós-vacinação pode ser menor do que na população geral. Entretanto, a vacina covid-19 está recomendada, considerando o risco de exposição. Acredita-se que pacientes com síndrome hemolítico-urêmica teriam maior risco de covid-19 grave. A vacina é recomendada, embora dados específicos sobre segurança e eficácia da vacina covid-19 sejam limitados. Há concordância que os benefícios da imunidade induzida superam quaisquer riscos da imunização. A vacina covid-19 é recomendada para crianças e adolescentes candidatos ao transplante renal ou já transplantados. Esses pacientes têm resposta imunológica reduzida após a vacina, entretanto ela é recomendada porque os benefícios superam qualquer risco dessa vacinação. A recomendação atual no Brasil é a vacina de tecnologia RNA mensageiro. O objetivo deste documento é levar aos nefrologistas pediátricos os conhecimentos mais recentes sobre a vacinação contra contra-19 em crianças com doenças renais. covid19 covid 19 covid-1 direta variantes PfizerBioNTech Pfizer BioNTech CoronaVac seguras imunogênicas imunossupressão seguro leve hospitalização eou pósvacinação pós geral Entretanto exposição Acreditase Acredita se hemolíticourêmica hemolítico urêmica limitados imunização transplantados mensageiro contra19 contra-1 renais covid1 1 covid- contra1 contra-

Resumen Se realizó una revisión de literatura con el objetivo de identificar los factores de riesgo de la BN, utiles para que el equipo de salud proteja la seguridad de sus intervenciones y atención a las personas que padecen este trastorno en el ciclo de vida adolescente y joven. Se hizo una búsqueda en bases de datos y repositorios, con uso de términos libres como: BN, adolescente, factor de riesgo, trastorno de conducta alimentaria, en español e inglés, combinados con operadores boleanos (AND, OR, NOT) y de posición (WTH y NEAR). Se incluyeron 72 documentos tras la selección por criterios de inclusión, se hizo depuración de ellos según sus datos bibliográficos, objetivo, tipo de estudio, resultados y conclusión. Los resultados muestran que hay aún factores biológicos por rastrear y analizar, dentro de los sociodemográficos, la edad de afectación principalmente reportada es la adolescencia y adultez joven, no hubo diferencias por raza o nivel socioeconómico. Factores comportamentales como preocupación por la imagen corporal, dietas y ejercicio son documentados. Desde el área psicosocial, la disfuncionalidad individual y los antecedentes de trastornos psicológicos, la familia y el entorno cultural condicionan para que el cuerpo logre su delgadez. La conclusión general sugiere que la seguridad de la atención en la BN está en explorar los antecedentes individuales, biológicos, psicológicos y comportamentales; reconocer dinámicas familiares y la influencia del entorno social. Asimismo, es útil, el trabajo interdisciplinar e integración de red de apoyo familiar para lograr atención segura en la BN.

Abstract Review of literature aimed at recognizing risk factors of BN, useful for the health team to protect the safety of their interventions and care for people suffering from this disorder in the adolescent and young life cycle. It consists of a narrative review, carried out by means of search in databases and repositories, with use of free terms such as: BN, adolescent, risk factor, food behavior disorders, in Spanish and English, combined with bolean operators (AND, OR, NOT) and position (WTH and NEAR). Seventy-two sources were incorporated, documents were selected by inclusion criteria, review according to bibliographic data, objective, type of study, results, and conclusion. The results show that there are still biological factors to be traced and analyzed, within the sociodemographic the age of involvement is adolescence and youth, it does not have differences by race or socioeconomic level. Behavioral factors such as concern for body image, diets and exercise are documented. From the psychosocial area, individual dysfunction and backgrounds of psychological disorders, the family and the cultural environment influence to achieve the thinness of the body. The general conclusion suggests that the safety of care in the BN lies in exploring the individual, biological, psychological and behavioral backgrounds, recognizing family dynamics and the influence of the social environment. It is useful, interdisciplinary work and integration of family support network to achieve safe health care in the BN.
