RESUMEN
Introdução: A terminalidade é uma situação cada vez mais vivenciada nos serviços de saúde em razão da progressão da expectativa de vida da população e, consequentemente, do incremento de pacientes com doenças crônicas graves. No Brasil, os serviços de cuidados paliativos ainda se encontram centralizados nos serviços de atenção terciária. Entretanto, em diversos países, a Atenção Primária à Saúde tem sido a grande prestadora e coordenadora de cuidados paliativos dos usuários, em prol da descentralização dessa assistência e da promoção do cuidado integral. Objetivo: Realizar uma revisão narrativa da literatura, a fim de identificar a relação dos médicos de família e comunidade na atuação de cuidados paliativos na Atenção Primária à Saúde. Métodos: Revisão bibliográfica por meio do acesso às bases de dados: Portal da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO) e PubMed. Foram selecionados 16 artigos, os quais foram submetidos a análise temática e posterior discussão das principais características que colaboram para a maior atuação dos médicos de família e comunidade em cuidados paliativos. Resultados: Observou-se a importância da atuação dos médicos de família e comunidade em cuidados paliativos no âmbito da Atenção Primária à Saúde, bem como a interligação entre as duas especialidades, os desafios existentes nesse caminho e os benefícios dessa prática. Conclusões: A oferta de cuidados paliativos pelos médicos de família e comunidade na atenção primária favorece o acesso e acompanhamento dos pacientes. Entretanto, a atuação dos profissionais das Equipes de Saúde da Família nessa linha de cuidado ainda é insuficiente em razão da escassa capacitação na área.
Introduction: Terminality is a situation increasingly experienced in healthcare services due to the progression of the population's life expectancy and, consequently, the increase in patients with serious chronic diseases. In Brazil, Palliative Care services are still centralized in tertiary care services. However, in many countries, Primary Health Care has been the major provider and coordinator of Palliative Care for users, in favor of decentralizing this assistance and promoting comprehensive care. Objective: To carry out a narrative literature review to identify the relationship of Family Practice Doctors in the performance of Palliative Care in Primary Health Care. Methods: Bibliographic review through access to databases: CAPES, LILACS, SciELO, and PUBMED. Sixteen articles were selected, which were submitted to thematic analysis and subsequent discussion of the main characteristics that contribute to the greater performance of Family Practice Doctors in Palliative Care. Results: The importance of Family Practice Doctors in Palliative Care within the scope of Primary Health Care was observed, as well as the interconnection between the two specialties, the challenges along this path, and the benefits of this practice. Conclusions: The offer of Palliative Care by Family Practice Physicians in Primary Care favors the access and monitoring of patients. However, the performance of the professionals in Family Health Teams in this line of care is still insufficient due to the lack of training in the area.

The primordial odontogenic tumor (POT) is a rare mixed odontogenic tumor composed of mesenchymal cells, columnar odontogenic epithelium, and fibromyxoid stroma affecting the posterior mandible of children and adolescents. Herein, we report 3 patients with POT and the clinicopathological features of POT previously reported in the literature. A 12-year-old, 19-year-old, and 4-year-old patient presented an asymptomatic swelling in the posterior maxilla and posterior mandible. Imaging exams revealed radiolucent lesions associated with unerupted teeth. The lesions were surgically removed, and the histopathological examination revealed spindle-to-ovoid mesenchymal cells in a fibromyxoid stroma surfaced by columnar odontogenic epithelial cells with reverse nuclear polarization. Deposition of mineralized tissue was observed. The final diagnosis was POT, and patients did not exhibit signs of recurrence. POT should be included in the differential diagnoses of intraosseous lesions in the posterior mandible in pediatric patients.
RESUMEN
Background: Oropouche virus (OROV; species Orthobunyavirus oropoucheense) is an arthropod-borne virus that has caused outbreaks of Oropouche fever in Central and South America since the 1950s. This study investigates virological factors contributing to the reemergence of Oropouche fever in Brazil between 2023 and 2024. Methods: In this study, we combined OROV genomic, molecular, and serological data from Brazil from 1 January 2015 to 29 June 2024, along with in vitro and in vivo characterization. Molecular screening data included 93 patients with febrile illness between January 2023 and February 2024 from the Amazonas State. Genomic data comprised two genomic OROV sequences from patients. Serological data were obtained from neutralizing antibody tests comparing the prototype OROV strain BeAn 19991 and the 2024 epidemic strain. Epidemiological data included aggregated cases reported to the Brazilian Ministry of Health from 1 January 2014 to 29 June 2024. Findings: In 2024, autochthonous OROV infections were detected in previously non-endemic areas across all five Brazilian regions. Cases were reported in 19 of 27 federal units, with 83.2% (6,895 of 8,284) of infections in Northern Brazil and a nearly 200-fold increase in incidence compared to reported cases over the last decade. We detected OROV RNA in 10.8% (10 of 93) of patients with febrile illness between December 2023 and May 2024 in Amazonas. We demonstrate that the 2023-2024 epidemic was caused by a novel OROV reassortant that replicated approximately 100-fold higher titers in mammalian cells compared to the prototype strain. The 2023-2024 OROV reassortant displayed plaques earlier than the prototype, produced 1.7 times more plaques, and plaque sizes were 2.5 larger compared to the prototype. Furthermore, serum collected in 2016 from previously OROV-infected individuals showed at least a 32-fold reduction in neutralizing capacity against the reassortment strain compared to the prototype. Interpretation: These findings provide a comprehensive assessment of Oropouche fever in Brazil and contribute to a better understanding of the 2023-2024 OROV reemergence. The recent increased incidence may be related to a higher replication efficiency of a new reassortant virus that also evades previous immunity.
RESUMEN
BACKGROUND: Glucagon-like peptide-1 agonist receptors (GLP-1RAs), medications used for glycemic control and weight loss, are increasing worldwide. In the perioperative period, the major concern related to GLP-1RA is gastric emptying delay and risk of aspiration. This meta-analysis and systematic review compared the risks and benefits of using GLP-1 agonist receptors and control in surgical and nonsurgical procedures under anesthesia or sedation. METHODS: We systematically searched MEDLINE, Embase, and Cochrane for randomized controlled trials and observational studies involving patients > 18 years undergoing elective surgeries or procedures. Outcomes of interest were pre-procedural gastrointestinal (GI) symptoms, residual gastric content assessed by endoscopy, pulmonary aspiration during anesthesia/sedation, perioperative glycemic control, postoperative inotropic support, nausea/vomiting (PONV), atrial fibrillation, and 30-day mortality rate. We used a random effects model, with odds ratio and mean difference computed for binary and continuous outcomes, respectively. RESULTS: Fourteen randomized and observational studies with 2143 adult patients undergoing elective surgeries and procedures were included. GLP-1RA resulted in increased pre-procedural GI symptoms (OR 7.66; 95% CI 3.42, 17.17; p < 0.00001; I2 = 0%) and elevated residual gastric content (OR 6.08; 95% CI 2.86, 12.94; p < 0.00001; I2 = 0%). GLP-1RA resulted in lower glycemic levels (MD - 0.73; 95% CI - 1.13, - 0.33; p = 0.0003; I2 = 90%) and lower rate of rescue insulin administration (OR 0.39; 95% CI 0.23, 0.68 p = 0.0009; I2 = 35%). There was no significant difference in rate of perioperative hypoglycemia (OR 0.60; 95% CI 0.29, 1.24; p = 0.17; I2 = 0%), hyperglycemia (OR 0.89; 95% CI 0.59, 1.34; p = 0.58; I2 = 38%), need for postoperative inotropic support (OR 0.57; 95% CI 0.33, 1.01; p = 0.05; I2 = 0%), atrial fibrillation (OR 1.02; 95% CI 0.52, 2.01; p = 0.95; I2 = 16%), rate of PONV (OR 1.35; 95% CI 0.82, 2.21; p = 0.24; I2 = 0%), and 30-day mortality rate (OR 0.54; 95% CI 0.14, 2.05; p = 0.25; I2 = 0%). CONCLUSION: Compared to control, pre-procedural GLP-1RA increased the rate of GI symptoms and the risk of elevated residual gastric content despite adherence to fasting guidelines. GLP-1RA improved glycemic control and decreased the rate of rescue insulin administration. There was no significant difference in the rates of perioperative hypo or hyperglycemia, postoperative inotropic support, PONV, atrial fibrillation, and 30-day mortality.
RESUMEN
Introduction: Triatomines are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Currently, there is no vaccine against this disease. Thus, control of the insect vector population is the main strategy available to reduce the number of cases. Triatomines are considered obligate hematophagous, but different alternative feeding behaviors were described, such as haemolymphagy or plant feeding. Methods: To determine the preference for sugar feeding in nymphs and adults of Rhodnius prolixus, the insects were exposed a piece of cotton containing bromophenol blue plus sucrose. In addition, we offered several sugars for different species of triatomines, and tested sugar meals as a route of delivery of insecticides in first-instar nymphs of R. prolixus. The effect of sugar feeding on the physiology of these different species of triatomines was recorded. Results: First instar nymphs ingested sucrose more strongly than other stages, and showed high mortality rates. In different species of triatomines, sucrose induced an ingestion, but engorgement varied according to the species. R. prolixus nymphs showed an indiscriminate intake of various sugars, with very different physiological effects. Furthermore, ingesting different combinations of insecticides + sugar significantly reduced insect survival. Discussion: In summary, we described for the first-time sugar feeding as a widespread behavior in several species of triatomines, and the possibility of the use of toxic sugar baits for the control of these vectors. The knowledge of feeding behavior in these insects can be fundamental for the development of new strategies to control Chagas disease.
RESUMEN
Tabanidae (Diptera), popularly known as horse flies, is an important vector group. This is the first study to ascertain the abundance and diversity of horse flies in horses at the cerrado biome of the state of Tocantins, Brazil. Collecting took place in typical Cerrado, and sampling occurred in the dry and rainy seasons. The horseflies were collected from horses using an entomological net. A total of 249 individuals were collected and spread over 25 species. The prevalent species were Stypommisa aripuana (25.8%) and Catachlorops rufescens (6.4%), in the dry period, and Fidena lissorhina (22.5%), Tabanus occidentalis var. dorsovittatus (10%) and Poeciloderas quadripunctatus (6.4%), in the rainy season. The results suggest that tabanids attack horses throughout the dry and rainy seasons, posing a constant threat to their health in the Cerrado of Tocantins.

BACKGROUND: Midazolam is routinely used as preanesthetic medication in pediatric patients. Recently, dexmedetomidine has emerged as an alternative as a premedicant. We aimed to add more evidence about the efficacy and safety of two common routes of administration for pediatric premedication: oral midazolam versus intranasal dexmedetomidine. METHODS: We systematically searched Randomized Controlled Trials (RCTs) involving patients ≤ 18 years old undergoing preanesthetic medication and comparing intranasal dexmedetomidine with oral midazolam. Risk Ratio (RR) and Mean Difference (MD) with 95% Confidence Intervals (95% CI) were computed using a random effects model. Trial-sequential analyses were performed to assess inconsistency. RESULTS: Sixteen RCTs (1,239 patients) were included. Mean age was 5.5 years old, and most procedures were elective. There was no difference in satisfactory induction or mask acceptance (RR = 1.15, 95% CI 0.97-1.37; p = 0.11). There was a higher incidence of satisfactory separation from parents in the dexmedetomidine group (RR = 1.40; 95% CI 1.13-1.74; p = 0.002). Dexmedetomidine was also associated with a reduction in the incidence of emergence agitation (RR = 0.35; 95% CI 0.14-0.88; p = 0.02). Heart rate and mean arterial pressure were marginally lower in the dexmedetomidine group but without clinical repercussions. CONCLUSION: Compared with oral midazolam, intranasal dexmedetomidine demonstrated better separation from parents and lower incidence of emergence agitation in pediatric premedication, without a difference in satisfactory induction. Intranasal dexmedetomidine may be a safe and effective alternative to oral midazolam for premedication in pediatric patients.

Breast cancer stands out as one of the most prevalent malignancies worldwide, necessitating a nuanced understanding of its molecular underpinnings for effective treatment. Hormone receptors in breast cancer cells substantially influence treatment strategies, dictating therapeutic approaches in clinical settings, serving as a guide for drug development, and aiming to enhance treatment specificity and efficacy. Natural compounds, such as curcumin, offer a diverse array of chemical structures with promising therapeutic potential. Despite curcumin's benefits, challenges like poor solubility and rapid metabolism have spurred the exploration of analogs. Here, we evaluated the efficacy of the curcumin analog NC2603 to induce cell cycle arrest in MCF-7 breast cancer cells and explored its molecular mechanisms. Our findings reveal potent inhibition of cell viability (IC50 = 5.6 µM) and greater specificity than doxorubicin toward MCF-7 vs. non-cancer HaCaT cells. Transcriptome analysis identified 12,055 modulated genes, most notably upregulation of GADD45A and downregulation of ESR1, implicating CDKN1A-mediated regulation of proliferation and cell cycle genes. We hypothesize that the curcumin analog by inducing GADD45A expression and repressing ESR1, triggers the expression of CDKN1A, which in turn downregulates the expression of many important genes of proliferation and the cell cycle. These insights advance our understanding of curcumin analogs' therapeutic potential, highlighting not just their role in treatment, but also the molecular pathways involved in their activity toward breast cancer cells.

The development of prophylactic vaccines is important in preventing and controlling diseases such as visceral leishmaniasis (VL), in addition to being an economic measure for public health. Despite the efforts to develop a vaccine against human VL caused by Leishmania infantum, none is available, and the focus has shifted to developing vaccines against canine visceral leishmaniasis (CVL). Currently, commercially available vaccines are targeted at CVL but are not effective. Different strategies have been applied in developing and improving vaccines, such as using chimeric proteins to expand vaccine coverage. The search for patents can be a way of tracking vaccines that have the potential to be marketed. In this context, the present work presents a summary of immunological aspects relevant to VL vaccine development with a focus on the composition of chimeric protein vaccines for CVL deposited in patent banks as an important approach for biotechnological development. The resulting data could facilitate the screening and selection of antigens to compose vaccine candidates with high performance against VL.
RESUMEN
BACKGROUND: In hematologic cancers, including leukemia, cells depend on amino acids for rapid growth. Anti-metabolites that prevent their synthesis or promote their degradation are considered potential cancer treatment agents. Amino acid deprivation triggers proliferation inhibition, autophagy, and programmed cell death. L-lysine, an essential amino acid, is required for tumor growth and has been investigated for its potential as a target for cancer treatment. L-lysine α-oxidase, a flavoenzyme that degrades L-lysine, has been studied for its ability to induce apoptosis and prevent cancer cell proliferation. In this study, we describe the use of L-lysine α-oxidase (LO) from the filamentous fungus Trichoderma harzianum for cancer treatment. RESULTS: The study identified and characterized a novel LO from T. harzianum and demonstrated that the recombinant protein (rLO) has potent and selective cytotoxic effects on leukemic cells by triggering the apoptotic cascade through mitochondrial dysfunction. CONCLUSIONS: The results support future translational studies using the recombinant LO as a potential drug for the treatment of leukemia.

Aim: To evaluate the surface roughness and color stability of bulk-fill resin composites after simulated toothbrushing with whitening dentifrices. The radioactive/relative dentin abrasion (RDA) and radioactive/relative enamel abrasion (REA) of dentifrices were also assessed. Methods: Specimens (n=10) of Tetric N Ceram Bulk Fill (TNCB), Filtek One Bulk Fill (FOB) resin composites, and Z100(Control) were prepared using a cylindrical Teflon matrix. Surface roughness (Ra, µm) was assessed by a roughness meter and the color evaluations (ΔEab , ΔE00 , WID ) were performed using a digital spectrophotometer based on the CIELAB system. Three measurements were performed per sample, before and after simulated toothbrushing with 3D Oral-B White Perfection (3DW) and Black is White (BW) dentifrices. The abrasivity (REA and RDA values) of the used dentifrices was also determined by the Hefferren abrasivity test. Results: The Ra values increased significantly in all resin composites after 3DW and BW toothbrushing. The acceptable threshold color varied among resin composites, and TNCB and Z100 presented the highest ΔEab and ΔE00 for BW dentifrice. The 3DW dentifrice was significantly more abrasive than BW dentifrice on enamel and dentin. Conclusions: simulated toothbrushing with tested whitening dentifrices increased the surface roughness at acceptable levels. The Tetric N Ceram Bulk-fill and Z100 composite showed the highest color alteration in BW. 3D White Perfection dentifrice was more abrasive on dentin and enamel than Black is White.

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment's functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats.
Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

RESUMEN
As the primary decision-maker about the health, nutrition, and well-being of their horses, owners' knowledge of correct management practices and clinical changes can potentially affect the immediate health of their horses, in addition to having an impact on the prevention of disease spread in the herd. The adoption of management practices to prevent the introduction and spread of pathogens depends on various factors, including demographics, awareness of the problem, perceived responsibility, previously held beliefs, and sociocultural norms. This study aimed to evaluate the health management practices and the level of knowledge about infectious diseases of equine owners in the state of Rio Grande do Norte, Brazil. A cross-sectional study was conducted by distributing a questionnaire to horse owners in Rio Grande do Norte, Brazil. The participants included horse owners irrespective of the duration of ownership, experience, or sports practiced. In addition to the hygiene and management of animals, the questionnaire addressed topics related to the facilities where the horses were kept. Three hundred and two horse owners distributed in 60 of the 167 municipalities in the state of Rio Grande do Norte participated in this study. Among the interviewed owners, 63.90% (193/302) answered that they do not quarantine animals introduced into the herd or those visiting the property. Regarding the deworming program, 95.03% (287/302) of the owners regularly dewormed their animals. However, more than half of the participants sought veterinary guidance (54.30%). Investing in educational programs and increasing the awareness of equine owners in the state of Rio Grande do Norte about the main infectious diseases in horses is essential toward improving sanitary management and the general health of animals. Informed owners play an essential role in creating safer environments for their horses, thereby contributing to the sustainability of the equine industry.
Como principal tomador de decisão sobre a saúde, nutrição e bem-estar de seus cavalos, o conhecimento dos proprietários sobre práticas corretas de manejo e mudanças clínicas pode potencialmente afetar a saúde imediata de seus cavalos, além de ter um impacto na prevenção de propagação das doenças no rebanho. A adoção de práticas de manejo para prevenir a introdução e disseminação de patógenos depende de uma variedade de fatores, incluindo dados demográficos, consciência do problema, responsabilidade percebida, crenças anteriores e normas socioculturais. Este trabalho teve como objetivo avaliar as práticas de manejo da saúde e o nível de conhecimento sobre doenças infecciosas de proprietários de equinos no estado do Rio Grande do Norte, Brasil Brasil. As amostras incluíram proprietários de cavalos, independentemente da duração da posse, experiência ou esporte praticado. O questionário abordou temas relacionados às instalações onde os cavalos eram mantidos, além do manejo higiênico-sanitário dos animais. Participaram do estudo 302 proprietários de cavalos distribuídos em 60 dos 167 municípios do estado do Rio Grande do Norte. Dentre os proprietários entrevistados, 63,90% (193/302) responderam que não colocam em quarentena os animais introduzidos no rebanho ou que estão visitando a propriedade. Em relação ao programa de desverminação, 95,03% (287/302) proprietários administravam vermifugação regularmente aos seus animais. No entanto, pouco mais da metade procura orientação veterinária (54,30%). Investir em programas de educação e conscientização dos proprietários de equinos do estado do Rio Grande do Norte sobre as principais doenças infecciosas em equinos é fundamental para melhorar o manejo sanitário e a saúde geral dos animais. Proprietários informados desempenham um papel essencial na criação de ambientes mais seguros para os cavalos, contribuindo para a sustentabilidade da indústria equina como um todo.
RESUMEN
Understanding and skills in psychotherapy are fundamental aspects of clinical psychiatry practice. Learning about psychotherapy during the training of psychiatrists offers solid opportunities for developing high standards of psychiatric practice and providing better outcomes for patients. However, little is known about the extent that psychotherapy training is available to psychiatrists in America. This study aimed to analyze the status of psychotherapy training in Brazil through the experiences of early-career psychiatrists. This is a cross-sectional survey conducted between July and November 2021. A 16-item questionnaire was used to investigate: the quality of psychotherapy training; the organizational aspects of psychotherapy training; and satisfaction with training in psychotherapy. The majority of participants reported having mandatory training in psychotherapy, mainly in cognitive-behavioral therapy and psychodynamic therapy. However, only had some practical experience with psychotherapy training. This study highlights the frequent use of psychotherapy training among Brazilian early career psychiatrists. The consensus on the necessity of mandatory psychotherapy training underscores its importance in shaping psychiatric practice. While participants express satisfaction with psychotherapy supervision, the financial burden for advanced training raises concerns. These findings advocate for the improvement of the quality of psychotherapy training in Brazil.

BACKGROUND: Alpha 1-antitrypsin deficiency (AATD) is a hereditary codominant autosomal disease. This liver disease ranges from asymptomatic cases to terminal illness, which makes early recognition and diagnosis challenging. It is the main cause of pediatric liver transplantation after biliary atresia. OBJECTIVE: To describe the clinical characteristics, as well as those of histologic and laboratory tests, phenotypic and/or genetic evaluation and evolution of a cohort of pediatric patients with AATD. METHODS: This is a retrospective observational study of 39 patients with confirmed or probable AATD (without phenotyping or genotyping, but with suggestive clinical features, low serum alpha 1-antitrypsin (AAT) level and liver biopsy with PAS granules, resistant diastasis). Clinical, laboratory and histological varia-bles, presence of portal hypertension (PH) and survival with native liver have been analyzed. RESULTS: A total of 66.7% of 39 patients were male (26/39). The initial manifestation was cholestatic jaundice in 79.5% (31/39). Liver transplantation was performed in 28.2% (11/39) of patients. Diagnosis occurred at an average of 3.1 years old and liver transplantation at 4.1 years of age. 89.2% (25/28) of the patients with confirmed AATD were PI*ZZ or ZZ. The average AAT value on admission for PI*ZZ or ZZ patients was 41.6 mg/dL. All transplanted patients with phenotyping or genotyping were PI*ZZ (or ZZ). Those who were jaundiced on admission were earlier referred to the specialized service and had higher levels of GGT and platelets on admission. There was no significant difference in the survival curve when comparing cholestatic jaundiced to non-cholestatic jaundiced patients on admission. Comparing patients who did or did not progress to PH, higher levels of AST and APRI score at diagnosis (P=0.011 and P=0.026, respectively) were observed and in the survival curves patients with PH showed impairment, with 20.2% survival with native liver in 15 years. CONCLUSION: Jaundice is an important clinical sign that motivates referral to a specialist, but it does not seem to compromise survival with native liver. Patients progressing to PH had higher AST, APRi score on admission and significantly impaired survival with native liver. It is important to pay attention to these signs in the follow-up of patients with AATD.

ABSTRACT Background: Alpha 1-antitrypsin deficiency (AATD) is a hereditary codominant autosomal disease. This liver disease ranges from asymptomatic cases to terminal illness, which makes early recognition and diagnosis challenging. It is the main cause of pediatric liver transplantation after biliary atresia. Objective: To describe the clinical characteristics, as well as those of histologic and laboratory tests, phenotypic and/or genetic evaluation and evolution of a cohort of pediatric patients with AATD. Methods: This is a retrospective observational study of 39 patients with confirmed or probable AATD (without phenotyping or genotyping, but with suggestive clinical features, low serum alpha 1-antitrypsin (AAT) level and liver biopsy with PAS granules, resistant diastasis). Clinical, laboratory and histological variables, presence of portal hypertension (PH) and survival with native liver have been analyzed. Results: A total of 66.7% of 39 patients were male (26/39). The initial manifestation was cholestatic jaundice in 79.5% (31/39). Liver transplantation was performed in 28.2% (11/39) of patients. Diagnosis occurred at an average of 3.1 years old and liver transplantation at 4.1 years of age. 89.2% (25/28) of the patients with confirmed AATD were PI*ZZ or ZZ. The average AAT value on admission for PI*ZZ or ZZ patients was 41.6 mg/dL. All transplanted patients with phenotyping or genotyping were PI*ZZ (or ZZ). Those who were jaundiced on admission were earlier referred to the specialized service and had higher levels of GGT and platelets on admission. There was no significant difference in the survival curve when comparing cholestatic jaundiced to non-cholestatic jaundiced patients on admission. Comparing patients who did or did not progress to PH, higher levels of AST and APRI score at diagnosis (P=0.011 and P=0.026, respectively) were observed and in the survival curves patients with PH showed impairment, with 20.2% survival with native liver in 15 years. Conclusion: Jaundice is an important clinical sign that motivates referral to a specialist, but it does not seem to compromise survival with native liver.

RESUMO Contexto: Deficiência de alfa 1-antitripsina (DAAT) é uma doença hereditária, de caráter autossômico codominante. A apresentação da doença hepática varia desde casos assintomáticos até doença terminal, o que dificulta reconhecimento e diagnóstico precoces. É a principal causa de transplante hepático pediátrico após atresia de vias biliares. Objetivo: Descrever as características clínicas, de exames laboratoriais, histológicos, avaliação fenotípica e/ou genética e sobrevida de uma coorte de pacientes pediátricos com DAAT. Métodos: Estudo observacional retrospectivo de 39 pacientes com diagnóstico de DAAT confirmada ou provável (sem fenotipagem ou genotipagem, mas com clínica sugestiva, baixo nível sérico de alfa 1-antitripsina (A1AT) e biópsia hepática com grânulos PAS, diástase resistentes). Variáveis clínicas, laboratoriais, histológicas, presença de hipertensão portal (HP) e sobrevida com fígado nativo foram analisadas. Resultados: Dos 39 pacientes, 66,7% eram do sexo masculino (26/39). A manifestação inicial foi icterícia colestática em 79,5% (31/39). Em 28,2% (11/39) houve necessidade de transplante hepático. O diagnóstico ocorreu com uma idade média de 3,1 anos e, o transplante hepático, 4,1 anos. Dos pacientes com DAAT confirmada, 89,2% (25/28) eram PI*ZZ ou ZZ. O valor médio de A1AT na admissão de pacientes PI*ZZ ou ZZ foi 41,6 mg/dL. Todos os transplantados com fenotipagem ou genotipagem eram PI*ZZ (ou ZZ). Os ictéricos à admissão foram referenciados mais cedo ao serviço especializado e apresentaram níveis mais elevados de GGT e plaquetas à admissão. Não houve diferença significativa na curva de sobrevida ao compararmos icterícia colestática ou não à admissão. Ao comparar os pacientes que progrediram ou não para HP, observou-se níveis mais elevados de AST e APRI escore ao diagnóstico (P=0,011 e P=0,026, respectivamente) e, nas curvas de sobrevida, pacientes com HP apresentaram comprometimento, com 20,2% de sobrevida com fígado nativo em 15 anos. Conclusão: Icterícia é um sinal clínico importante que motiva o encaminhamento ao especialista, mas parece não comprometer a sobrevida com fígado nativo. Pacientes com evolução para HP tiveram AST e escore APRi mais elevados à admissão e comprometimento significativo da sobrevida com fígado nativo. Importante atentar a esses sinais no seguimento de pacientes com DAAT.
RESUMEN
OBJECTIVE: To determine the clinical profile of COVID-19 inpatients who were vaccinated prior to hospitalization and to compare the risk factors for death and the 28-day survival rate of between those inpatients vaccinated with one, two, or three doses and unvaccinated COVID-19 inpatients. METHODS: This was a retrospective observational cohort study involving COVID-19 patients admitted to a referral hospital in the city of Recife, Brazil, between July of 2020 and June of 2022. RESULTS: The sample comprised 1,921 inpatients, 996 of whom (50.8%) were vaccinated prior to hospitalization. After adjusting the mortality risk for vaccinated patients, those undergoing invasive mechanical ventilation (IMV) had the highest mortality risk (adjusted OR [aOR] = 7.4; 95% CI, 3.8-14.1; p < 0.001), followed by patients > 80 years of age (aOR = 7.3; 95% CI, 3.4-15.4; p < 0.001), and those needing vasopressors (aOR = 5.6; 95% CI, 2.9-10.9; p < 0.001). After adjusting the mortality risk for all patients, having received three vaccine doses (aOR = 0.06; 95% CI, 0.03-0.11; p < 0.001) was the most important protective factor against death. There were progressive benefits of vaccination, reducing the frequency of ICU admissions, use for IMV, and death (respectively, from 44.9%, 39.0% and 39.9% after the first dose to 16.7%, 6.2% and 4.4% after the third dose), as well as significant improvements in survival after each subsequent dose (p < 0.001). CONCLUSIONS: Vaccines were effective in reducing illness severity and death in this cohort of COVID-19 inpatients, and the administration of additional doses conferred them with accumulative vaccine protection.

Objetivo: Relatar o processo de diagnóstico e tratamento de um queratocisto odontogênico (QO) em seio maxilar e a sua importância na investigação e diagnóstico de Síndrome de Gorlin-Goltz (SGG). Relato de caso: Paciente do gênero feminino, 20 anos, apresentou-se no serviço de odontologia encaminhada pela equipe de genética médica para investigar a presença de QO para definição de diagnóstico de SGG. Foi realizada radiografia panorâmica e verificou-se a presença de alterações no trabeculado ósseo em tuberosidade maxilar do lado esquerdo. Por isso, foi solicitada a tomografia computadorizada de seios maxilares e encontrou-se uma lesão bem delimitada, ocupando quase completamente o seio maxilar esquerdo em íntimo contato com a raiz do dente 27. Portanto, foi realizada biópsia incisional da lesão, acompanhada da aspiração do conteúdo. Na aspiração foi obtido um conteúdo de característica caseosa sugestivo de queratina. O laudo histopatológico da lesão foi de cisto odontogênico. Com isso, foram realizados os procedimentos de exodontia do dente 27 e a enucleação da lesão em seio maxilar pela equipe da odontologia e da otorrinolaringologia, respectivamente, em centro cirúrgico. O laudo histopatológico confirmou a presença de QO, assim foi possível confirmar o diagnóstico da SGG pela equipe da genética médica. A paciente não apresentou sinais de recidiva e nem de novos QO após 2 anos do procedimento. Considerações finais: A SGG requer atenção odontológica especial, visto a alta taxa de QO nos pacientes com essa síndrome. Exame odontológico minucioso envolvendo exame clínico e exames radiográficos devem ser realizado nas consultas de seguimento.
Objective: To report the process of diagnosis and treatment of an odontogenic keratocyst (OK) in the maxillary sinus and its importance in the investigation and diagnosis of Gorlin-Goltz Syndrome (GGS). Case report: A 20-year-old female patient presented at the Dentistry and Stomatology service, referred by the Medical Genetics team to investigate the presence of OK to define the diagnosis of GGS. Panoramic radiography was performed and the presence of alterations in the bone trabeculae in the maxillary tuberosity on the left side was verified. For this reason, computed tomography of the maxillary sinuses was also requested and a well-defined lesion was found, occupying almost completely the left maxillary sinus in close contact with the root of tooth 27. Therefore, an incisional biopsy of the lesion was performed, accompanied by puncture of the same. In the puncture, a characteristic caseous content suggestive of keratin was obtained. The histopathological report of the lesion was described by the pathologist as an odontogenic cyst. With this, tooth extraction procedures for tooth 27 and enucleation of the lesion in the maxillary sinus were carried out by the dentistry and otorhinolaryngology teams, respectively, in a surgical center. The histopathological report confirmed the presence of OK, so it was possible to confirm the diagnosis of GGS by the medical genetics team. The patient showed no signs of recurrence or new OK after 2 years of the procedure. Final considerations: GGS requires special dental attention, given the high rate of OK in patients with this syndrome. A thorough dental examination involving clinical examination and radiographic examinations should be performed at follow-up visits.
