Introduction: Autism spectrum disorder is a neuropsychiatric condition that demands interdisciplinary and multidisciplinary attention. Nutritional intervention is necessary in the face of possible associated symptoms, such as food selectivity and changes in bowel habits. Families living in places with limited access to health services may have difficulties in obtaining adequate support and follow-up.Objective: Reporting the experience of nutrition services provided by the Academic League of Nutrition and Public Health to children with autism spectrum disorder, exploring the main identified demands and challengesfaced in a remote access region. Methodology:Descriptive approach, experience of an report, of services provided in the municipality of Coari, in the interiorof Amazonas. The meetings were held with the aim identifying demands and reflecting on the best way to assistchildren with these comorbidities. Results: Ninechildren attended to, not all with a confirmed diagnosis. Food selectivity, gastrointestinal disorders and overweight were recurring challenges. There is a lack of perception of the importance of nutritional monitoring, in a scenario where there areimportant reportsofdifficulties in accessing medications, either due to lack of availability in the municipality or lack of resources for acquisition, as well as specialized therapies. Theseaspects become even more challenging given the geographical distance and scarcity of specialized professionals whocanprovide multidisciplinary care. Conclusions: Adequate nutritional monitoring is essential to meet the specific needs and improve the quality of life of these children. Given the limitations identified in the region, continuous efforts are needed to develop solutions that guarantee inclusive and effective assistance for children with autism spectrum disorder in the interior of Amazonas. Collaboration between institutions, community awareness, and strengthening the local health network are crucial to promoting a comprehensive, high-quality approach for these children and their families (AU).

ABSTRACT We report a case of bilateral acute depigmentation of the iris in which satisfactory intraocular pressure control was obtained after resolution of the acute disease with a trabecular implant (iStent®). A 62-year-old woman presented with bilateral simultaneous acute eye pain, photophobia, increased intraocular pressure (34 mmHg), circulating pigment in the anterior chamber, areas of depigmentation in the iris, and posterior synechiae. She had received oral amoxicillin-clavulanate and moxifloxacin for pneumonia 2 months previously. Bilateral acute depigmentation of the iris was suspected as well as a viral etiology. She received oral acetazolamide, aciclovir, and prednisone, besides topical prednisolone, betaxolol, brimonidine, dorzolamide, and atropine. The disease gradually resolved in 4 months but, after 1 year, she developed bilateral cataracts, and still needed three drugs for intraocular pressure control (16/18 mmHg). Cataract-iStent® combined surgery was performed in both eyes. One year after surgery, intraocular pressure was 11/12 mmHg, without medication. iStent® was safe and effective on this secondary glaucoma.
RESUMO Relatamos um caso de despigmentação aguda bilateral da íris, no qual obtivemos adequado controle da pressão intraocular com o implante do iStent®, após resolução da fase aguda da doença. Paciente feminina, 62 anos, atendida com quadro agudo, bilateral e simultâneo de dor ocular, fotofobia, hipertensão ocular (34 mmHg), pigmentos circulantes na câmara anterior, áreas de despigmentação iriana e sinéquias posteriores. Havia recebido amoxicilina-clavulanato e moxifloxacina orais para pneumonia 2 meses antes. Suspeitando-se de despigmentação aguda bilateral da íris ou de etiologia viral, recebeu acetazolamida, aciclovir e prednisona orais, e colírios prednisolona, betaxolol, brimonidina, dorzolamida e atropina. O quadro se resolveu gradualmente em 4 meses, porém, após 1 ano, desenvolveu catarata bilateral e ainda usava 3 colírios hipotensores (pressão intraocular 16/18 mmHg). A cirurgia combinada de catarata-iStent® foi realizada em ambos os olhos. Um ano depois, a pressão intraocular mantinha-se 11/12 mmHg, sem medicação. O iStent® foi seguro e eficaz no controle deste glaucoma secundário.
RESUMO
ABSTRACT Objectives: to assess patient safety culture during the COVID-19 pandemic and identify the dimensions that need to be improved in hospital settings and which sector, open or closed, direct or indirect care, exhibits a higher level of safety culture. Methods: a descriptive and cross-sectional study. The validated version for Brazil of the Hospital Survey on Patient Safety Culture instrument was applied to assess patient safety culture. Those dimensions with 75% positive responses were considered strengthened. Results: all dimensions presented results lower than 75% of positive responses. Closed sectors showed a stronger safety culture compared to open ones. Indirect care sectors had a low general perception of patient safety when compared to direct care sectors. Conclusions: with the pandemic, points of weakness became even more evident, requiring attention and incisive interventions from the institution's leaders.

RESUMO
Amazonian flora includes several species with the potential to develop pharmaceutical and biotechnological products. The essential oils from Amazonian species possess some biological properties, such as antioxidant, antibacterial, and cytotoxic activities. The essential oil of red sacaca (RSO), Croton cajucara Benth., contains metabolites characterized by antioxidant and anti-inflammatory activities. Nanostructured lipid carriers (NLC) are an advantageous alternative for the effective delivery of drugs because they can solubilize lipophilic actives and reduce their cytotoxicity. This study aimed to optimize the synthesis of RSO-loaded nanostructured lipid carriers (NLC-RSO) using a 23 factorial design and investigate their antioxidant and cytotoxic effects. The red sacaca essential oil (RSO) metabolite profile was characterized using gas chromatography coupled with a mass spectrometer (GC-MS), identifying 33 metabolites, with linalool and 7-hydroxy-calamenene as the major ones, as reported in the literature. The optimized NLC-RSO formulation had a particle size less than 100 nm and a polydispersity index lower than 0.25. After characterizing NLC-RSO using Fourier-transform infrared spectroscopy, powder X-ray diffraction, zeta potential, moisture content, and wettability, in vitro cytotoxicity were performed in A549 and BEAS-2B cell lines using the resazurin metabolism assay. The data indicated a lower IC50 for RSO than for NLC-RSOs in both cell lines. Furthermore, low cytotoxicity of blank nanoparticles (blank NP) and medium chain triglycerides-loaded nanostructured lipid carriers (NLC-MCT) towards both pulmonary cell lines was noted. At a concentration of 50-100 µg/mL, free RSO exhibited higher cytotoxicity than NLC-RSO, demonstrating the protective effect of this lipid carrier in reducing cytotoxicity during metabolite delivery. Similarly, free RSO showed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging than NLC-RSO, also indicating this protective effect. The 2',7'-dichlorofluorescein diacetate (DCFH-DA) intracellular reactive oxygen species (ROS) level assay did not show differences between the treatments at higher but non-cytotoxic dosages. Taken together, our results suggest that NLC-RSOs are potential RSO delivery systems for applications related to cancer treatment.
RESUMO
Metal contamination poses a significant threat to elasmobranchs, underscoring the need for targeted conservation approaches. The critically endangered Brazilian guitarfish, Pseudobatos horkelii, confronts an array of challenges, notably overexploitation, putting its survival at risk. Our study investigated the potential toxicity arising from arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) contamination across various adult guitarfish tissues from southeastern Brazil. Serological stress indicators, nutritional metabolites, and creatinine, an organ function marker, were also assessed, and Selenium (Se) levels were also investigated for possible protective effects. Our investigation unveiled significant correlations between metal concentrations and the determined physiological markers, shedding light on potential adverse effects. Remarkably, six correlations were indicative of how Hg and Pb negatively impact hepatic metabolite assimilation, while As was shown to influence renal phosphorus dynamics, Cd to affect rectal gland phosphorus regulation, and Pb to influence creatinine production in muscle tissue. Furthermore, Se demonstrated protective properties against Cd, Hg, and Pb, suggesting a role in alleviating the toxicity of these elements. Despite probable protective Se influences, the detected elemental interactions still suggest potential for organ impairment. These findings gain heightened significance within the context of the cumulative stressors faced by the Brazilian guitarfish, with metal contamination exhibiting the capacity to erode this species resilience against both anthropogenic and environmental pressures, thereby disrupting systemic equilibrium and jeopardizing wild populations. By investigating the intricate balance between metal accumulation and physiological consequences, our study contributes with crucial insights into potential conservation strategy formulations towards pollution for this critically endangered elasmobranch species.

Simplexvirus humanalpha1 (HSV-1) aï¬ects approximately 67% of the world's population. Here, we sought to use the CRISPR / Cas9 system with the UL39 target, essential for virus replication. The sgRNA sequence was inserted into the plasmid (PX459-UL39). Vero cells were transfected with PX459-UL39, and inhibition of viral replication was assessed 24 and 48 hours later using plaque assays and ï¬uorescence and qPCR. Fluorescence analyses revealed the presence of anti-HSV-1 CRISPR/Cas9 within Vero cells, and qPCR showed that the viral load decreased by> 95% of cells transfected with anti-HSV-1 CRISPR / Cas 9. Our data demonstrate the usefulness of the PX459-UL39 to inhibit HSV-1 infection.

The current climate change scenario caused by anthropogenic activities has resulted in novel environmental pressures, increasing the occurrence and severity of fungal infections in the marine environment. Research on fungi in several taxonomic groups is widespread although not the case for elasmobranchs (sharks and rays). In this context, the aim of the present study was to screen the oral fungal microbiota present in artisanally captured Rioraja agassizii, a batoid that, although endangered, is highly fished and consumed worldwide. Oropharyngeal samples were obtained by swabbing and the samples were investigated using morphological and phenotypic methods by streaking on Sabouraud Dextrose Agar (SDA) and subculturing onto CHROMagar Candida (BD Difco) and CHROMagar Candida Plus (CHROMagarTM), as well as molecular techniques by amplification of the ITS1-5.8S-ITS2 ribosomal DNA region and a MALDI-TOF MS assessment. The findings indicated the presence of Candida parapsilosis (seven isolates), Candida duobushaemulonii (one isolate) and Rhodotorula mucilaginosa (three isolates), several of these reported for the first time in Rioraja agassizii. In addition, a 100% agreement between the MALDI-TOF results and partial ITS region sequencing was noted, demonstrating that the MALDI-TOF MS is a rapid and effective alternative for yeast identification in Rioraja agassizii isolates and potentially in other elasmobranch species. These findings highlight the need for further research to determine the potential impact on elasmobranch health, ecology, and commercial fisheries. Furthermore, this research is paramount in a One Health framework and may be employed to predict elasmobranch responses to an evolving ocean, keep healthy populations in check, monitor species, and assess the public health consequences of consuming these species.
RESUMO
The oil and gas industries are the largest producers of NORM wastes that are continuously generated during production and extraction activities. In addition, an increasing trend is observed in waste production worldwide due to the decommissioning of oil platforms. The problem is that most of these wastes are in activity concentration levels above the exemption and the clearance limits and are being accumulated in storage sites because no repositories exist in Brazil for NORM wastes generated by oil industries. There are regulations for radioactive wastes and for the licensing of repositories for managing wastes with low and intermediate levels of radiation but the current regulations apply only to packaged wastes. Therefore an initial radiological assessment was carried out with the RESRAD-OFFSITE code to show that bulk NORM wastes (not packaged wastes) could be disposed of in repositories near the surface without causing additional risk to the public above the criteria used. The results can also support decision-making by the Regulatory Authority to change the current regulations and allow for the disposal of wastes in bulk form.

Vesicular stomatitis caused by Alagoas vesiculovirus (VSAV) has generated disease outbreaks in Brazil, mainly in the northeast region. Phylogenetic studies divide the isolates into three distinct genotypes (A, B, and C). However, there is no description of how this genetic divergence reflects on the phenotype of VSAV isolates such as in vitro replication fitness. Therefore, the objective of this work was to evaluate the ability of three distinct genotypes of Brazilian isolates of VSAV to grow in different cell-culture lines (BHK-21, Vero, and NCI-H1299). Quantification of viral RNA was performed using RT-PCR digital droplet from supernatant of cell culture collected every 4 h for a period of 24 h of viral growth in three different cell lines (BHK-21, Vero, and NCI-H1299). It was observed that the genotype C isolate has the lowest replication efficiency among the three analyzed viruses, without major changes in the copies of viral RNA over the entire time of the study.

The barrier discharge ionization detector (BID) is one of the latest detection technologies used in gas chromatography (GC). 306 papers from 2012 to 2021 with GC-BID analyses were considered. An overview of the main applications with the BID, considering the trends for the most common analyses, explored compounds, extraction methods, and comparative studies with other detectors is shown. Interest in BID applications has grown, and the number of publications reflects this. Despite having the potential to analyze different compounds, gases are more explored, mainly H2, CH4, and CO. The BID should be further explored for water analysis, as studies show its good performance in larger quantities and at the level of traces. Most of the determinations of these compounds were applied in studies focused on CO2 reduction (by photocatalysis or electro-reduction) and biogas (for CH4). BID is effective for determinations on the order of mmol to µmol. Headspace extraction (HS) is most often applied BID analysis. Reduced dynamic range and nonlinear response to carbon mass are some disadvantages to BID. On the other hand, the BID has a signal-to-noise ratio (S/N) 100 times higher than thermal conductivity detector (TCD) (for inorganic gases and water), a high linear sensitivity for dodecane (LOD less than 1.0 pgC/sec) and other compounds (being able to reach µg/L). Combined with simple extraction methods such as HS, the BID allows quick and simple analysis with great sensitivity, in addition, it is a good alternative for the analysis of inorganic gases and water compared to usual detectors.
