Molecular genetic association of rs8099917 and rs1800795 polymorphisms in the progression of hepatitis Delta virus liver disease

Background: The relationship between viral infections and host factors holds high hopes for identifying the role of Interferon Lambda 3 (IFNL3) and Interleukin 6 (IL-6) polymorphisms in the development of Chronic Liver Disease (CLD) in patients infected with hepatitis Delta virus (HDV) in the Western Brazilian Amazon. Methods: Cross-sectional study conducted with a cohort of 40 chronic HDV patients, 27 with CLD and 13 without evident liver damage. Biological samples from the participants were analyzed using the polymerase chain reaction (PCR) technique, followed by sequencing by the automated Sanger method. Results: The rs8099917 T allele, from the IFNL3 gene, showed a higher frequency in both groups; however, it was not possible to establish an association with HDV infection [OR = 1.42 (0.42 - 4.75; p = 0.556 (95% CI). For IL-6, the rs1800795 G allele was superior to rs1800795 C. Analyzing both distributions in the studied groups, any association with HDV was absent (p > 0.05). Conclusion: The results suggest that the rs8099917 T/G (IFNL3) and rs1800795 G/C (IL-6) polymorphisms are not associated with the evolution of HDV in the studied population.

Pacientes em pós-operatório imediato: recepção na unidade clínico-cirúrgica / Patients in the immediate postoperative period: admission to the clinical and surgical unit

Objetivo: Analisar a demanda de enfermagem nos cuidados de pacientes em pós-operatório imediato, desde sua recepção do centro cirúrgico até sua acomodação ao leito na unidade de internação. Métodos: Estudo prospectivo e analítico. A população foi constituída por pacientes adultos, egressos do centro cirúrgico. A amostra foi calculada considerando-se que o serviço realiza uma média de 118 cirurgias ao mês. Considerando que a amostra mínima seria de 91 pacientes com um intervalo de confiança de 95%, optou-se por trabalhar com amostra de 100 pacientes. Os dados foram coletados no momento em que os pacientes eram recebidos da SRPA. Resultados: Os grupos cirúrgicos Angiologia, Coloproctologia, Otorrinolaringologia e Urologia demandaram no máximo dois profissionais de enfermagem. Os grupos de Cirurgia de Cabeça e Pescoço, Cirurgia Plástica, Nefrologia e Ortopedia demandaram pelo menos dois profissionais. O grupo da Coloproctologia teve maior média de tempo de acomodação ao leito. Cerca de 15% dos pacientes demandaram oxigenoterapia, quase 50% receberam analgésicos e 34% estavam usando cateter vesical de demora. Conclusão: O tempo destinado à acomodação dos pacientes variou de 5 a 30 minutos, com média de 15,19 ± 4,7. Não há indícios de que mais ou menos profissionais atuando juntos alterem o tempo de acomodação do paciente. Descritores: Admissão do paciente; Transferência do paciente; Cuidados de enfermagem; Enfermagem perioperatória.

Objective: To analyze the nursing demand in the care of patients in the immediate postoperative period, from their admission to the surgical center to their accommodation in bed in the admission unit. Methods: Prospective and analytical study. The population consisted of adult patients, discharged from the surgical center. The sample was calculated considering that the service performs an average of 118 surgeries per month. Considering that the minimum sample would be 91 patients at a 95% confidence interval, we chose to work with a sample of 100 patients. Data were collected at the time patients were received from the PACU. Results: The Angiology, Coloproctology, Otorhinolaryngology and Urology surgical groups required a maximum of two nursing professionals. The Head and Neck Surgery, Plastic Surgery, Nephrology and Orthopedics groups required at least two professionals. The Coloproctology group had a higher average time of accommodation in bed. About 15% of the patients required oxygen therapy, almost 50% received analgesics and 34% were using an indwelling urinary catheter. Conclusion: The time allocated to the accommodation of patients ranged from 5 to 30 minutes, with an average of 15.19 ± 4.7. There are no indications that a greater or lesser number of professionals acting together alter the accommodation time of the patient.

Rare CFTR large deletions: a series of cases / Grandes deleções raras no CFTR: uma série de casos

Aims: this paper aims to describe diagnosis and follow-up of patients affected by the Cystic Fibrosis (CF) manifestations and CFTR large deletions. For this, we performed a retrospective analysis of medical records, including genotyping and retrospective follow-up of clinical and lung function data. Electronic and printed medical records of patients followed at a referral outpatient clinic in CF were evaluated. Case description: we found that three patients had large deletions in the CFTRgene, being two of them heterozygous (heterozygous with deletion on exons from 2 to 3, and heterozygous for deletions on exons from 25 to 27) and one of them homozygous (homozygous for the deletions on exons from 19 to 21). One patient had a false negative result in complete genetic sequencing. All three received standard treatment for CF. Two patients died from CF pulmonary complications. Therefore, false negatives findings in CFTR sequencing for the diagnosis of CF are rare but may be more frequent in patients with large deletions. Conclusions: CFTR large deletions are associated with severe CF phenotypes

Objetivo: este trabalho tem como objetivo descrever o diagnóstico e o acompanhamento de pacientes acometidos pelas manifestações da fibrose cística e grandes deleções do gene CFTR. Para isso, realizamos análise retrospectiva de prontuários, incluindo genotipagem e acompanhamento retrospectivo de dados clínicos e de função pulmonar. Descrição dos casos: foram avaliados prontuários eletrônicos e impressos de pacientes acompanhados em ambulatório de referência em fibrose cística. Encontramos três pacientes com grandes deleções no gene CFTR, sendo dois deles heterozigotos (heterozigotos com deleção nos éxons de 2 a 3 e heterozigotos para deleções nos éxons de 25 a 27) e um deles homozigoto (homozigoto para as deleções nos éxons de 19 a 21,). Um paciente apresentou resultado falso negativo no sequenciamento genético completo. Todos os três receberam tratamento padrão para fibrose cística. Dois pacientes morreram de complicações pulmonares da fibrose cística. Portanto, achados falsos negativos no sequenciamento CFTR para o diagnóstico de fibrose cística são raros, mas podem ser mais frequentes em pacientes com grandes deleções. Conclusão: grandes deleções de CFTR estão associadas a fenótipos graves de FC

Resection of ankle tumor lesion and reconstruction with the use of allograft / Ressecção de lesão tumoral do tornozelo e reconstrução com uso de aloenxerto

RESUMO A reconstrução do terço distal da tíbia devido à ressecção de tumor maligno apresenta alguns fatores que dificultam sua realização, como camada subcutânea delgada, feixes neurovasculares que transpassam os compartimentos, tempo cirúrgico prolongado, material ortopédico específico e equipe multidisciplinar treinada. O aloenxerto de banco de tecido faz parte deste arsenal ortopédico. Objetivo: Descrever o protocolo realizado no Instituto Nacional de Traumatologia e Ortopedia Jamil Haddad. Métodos: Série de seis casos submetidos à ressecção com margens oncológicas, reconstrução com aloenxerto e uso de haste retrógrada de tornozelo como cirurgia preservadora do membro. Três dos seis pacientes eram do sexo feminino, as lesões tinham em média 9,3 cm de comprimento e o tempo cirúrgico médio foi de 3,25 horas. Resultados: A principal complicação de curto prazo (≤ 30 dias) foi a paralisia do nervo fibular, enquanto a principal complicação de longo prazo (> 30 dias) foi a infecção do sítio cirúrgico (dois casos). A consolidação dos dois focos ocorreu em três pacientes, e dois pacientes evoluíram para pseudoartrose assintomática do foco proximal com consolidação do foco distal. Conclusão: Apesar das complicações, a cirurgia proposta permite ao paciente a chance de preservar seu membro diante de uma cirurgia radical imediata. Nível de Evidência IV, Série de Casos.

ABSTRACT Reconstruction of the distal third of the tibia due to resection of a malignant tumor has some hindering factors, such as a thin subcutaneous layer, neurovascular bundles that cross compartments, prolonged operative duration, specific orthopedic material, and a trained multidisciplinary team. Allografting with material from tissue banks is part of this orthopaedic arsenal. Objective: To describe the protocol used at Instituto Nacional de Traumatologia e Ortopedia Jamil Haddad. Methods: Series of six cases subjected to resection with oncologic margins, allograft reconstruction, and use of a retrograde ankle nail as limb-salvage surgery. Three of the six patients were women, the lesions were on average 9.3 cm long, and the average operative duration was 3.25 hours. Results: The main short-term complication (≤ 30 days) was peroneal nerve palsy, while the main long-term complication (> 30 days) was surgical site infection (two cases). Consolidation of the two foci occurred in three patients, and two patients developed asymptomatic pseudoarthrosis of the proximal focus with consolidation of the distal focus. Conclusion: Despite the complications, the proposed surgery gives patients the chance to preserve their limb in the face of immediate radical surgery. Level of Evidence IV, Case Series.

Study of laser fluorescence spectroscopy in livers of rats with hypothermic ischemia

Purpose: After partial hepatectomy (PH), the remaining liver (RL) undergoes regenerative response proportional to the host. Limited literature exists on hepatic viability after tissue injury during hypothermic preservation. Spectroscopy measures cellular fluorescence and is explored for tissue characterization and parameter investigation. This study aimed to assess fluorescence analysis (spectroscopy) in evaluating liver viability and its relationship with hepatic tissue regeneration 24 hours after PH. Additionally, we analyzed liver regeneration in RL after 70% partial hepatectomy under hypothermic conditions with laser irradiation. Methods: Fifty-six Wistar rats were divided into four groups: total non-perfused liver (control), total perfused liver, partial hepatectomy "in situ", and partial hepatectomy "ex situ". Tissue analysis was performed at 0 and 24 hours using spectroscopy with laser devices emitting at 532 (green) and 405 nm (violet). Results: Spectroscopy identified tissue viability based on consistent results with Ki67 staining. The fluorescence spectra and Ki67 analysis displayed similar patterns, linking proliferative activity and absorption intensity. Conclusions: Fluorescence spectroscopy proves to be promising for real-time analysis of cellular activity and viability. Metabolic activity was observed in groups of live animals and hypothermically preserved samples, indicating cellular function even under blood deprivation and hypothermic conditions.

Antimalarials and macrolides: a review of off-label pharmacotherapies during the first wave of the SARS-CoV-2 pandemic

Abstract We critically analyzed clinical trials performed with chloroquine (CQ) and hydroxychloroquine (HCQ) with or without macrolides during the first wave of COVID-19 and discussed the design and limitations of peer-reviewed studies from January to July 2020. Seventeen studies were eligible for the discussion. CQ and HCQ did not demonstrate clinical advantages that justified their inclusion in therapeutic regimens of free prescription for treatment or prophylactic purposes, as suggested by health authorities, including in Brazil, during the first wave. Around August 2020, robust data had already indicated that pharmacological effects of CQ, HCQ and macrolides as anti-SARS-CoV-2 molecules were limited to in vitro conditions and largely based on retrospective trials with low quality and weak internal validity, which made evidence superficial for decision-making. Up to that point, most randomized and nonrandomized clinical trials did not reveal beneficial effects of CQ or HCQ with or without macrolides to reduce lethality, rate of intubation, days of hospitalization, respiratory support/mechanical ventilation requirements, duration, type and number of symptoms, and death and were unsuccessful in increasing virus elimination and/or days alive in hospitalized or ambulatory patients with COVID-19. In addition, many studies have demonstrated that side effects are more common in CQ-or HCQ-treated patients.

Cutaneous metastases from solid neoplasms - Literature review

Abstract Cutaneous metastases from solid tumors are uncommon events in clinical practice. Most of the time, the patient already has the diagnosis of a malignant neoplasm when the cutaneous metastasis is detected. However, in up to one-third of cases, cutaneous metastasis is identified before the primary tumor. Therefore, its identification may be essential for starting treatment, although it is usually indicative of poor prognosis. The diagnosis will depend on clinical, histopathological, and immunohistochemical analysis. Sometimes the identification of the primary site is difficult; however, a thorough analysis using imaging tests and constant surveillance is important.

Antimicrobial resistance of Pseudomonas aeruginosa isolated from patients with pneumonia during the COVID-19 pandemic and pre-pandemic periods in Northeast Brazil

Healthcare-related infections caused by resistant microorganisms are a severe public health problem and are becoming increasingly prevalent in the hospital environment, especially Pseudomonas aeruginosa. This work aimed to evaluate the resistance profile of Pseudomonas aeruginosa to antimicrobials before the COVID-19 pandemic and during the pandemic period. Bacteria strains were obtained from tracheal aspiration, sputum, and bronchoalveolar lavage for diagnosis and phenotypic characterization. Matrix assisted laser-desorption ionization-time of flight mass spectrometry (MALD-TOF MS) was used to identify strains. Automated Phoenix and VITEK® 2 Compact system and the disc diffusion method were performed to determine the antimicrobial susceptibility profile. A total of 41,000 medical reports from adult patients with pneumonia were analyzed. Of these, 951 patients were positive for P. aeruginosa, of which 373 were related to the pre-pandemic period and 578 to the pandemic period. Older men (≥60 years) were more prevalent in both periods. P. aeruginosa strains were resistant to imipenem in both periods: 38.8 and 42.5%, respectively, followed by meropenem (34.2 and 39.2%), ciprofloxacin (33.6 and 36.7%), and levofloxacin (34.9 and 43.5%). Intensive care units had the highest percentage of affected patients (62 and 65%) compared with other sectors, with a prevalence of 71% in the public network before COVID-19 and 59% during the pandemic. Our data showed a prevalence of P. aeruginosa in elderly patients in both the pre-pandemic and pandemic periods. In addition, an increase in P. aeruginosa resistance to beta-lactams, quinolones, carbapenems, and cephalosporins was observed during the COVID-19 pandemic compared with the period before the pandemic, especially in ICUs.

Correlação entre a Circunferência de Cintura e Medidas Centrais da Pressão Arterial / Correlation among Waist Circumference and Central Measures of Blood Pressure

Resumo Fundamento: A rigidez arterial é um forte preditor de doença cardiovascular (DCV). Medidas de gordura corporal, como a circunferência da cintura (CC), têm sido associadas à DCV na idade adulta. Objetivos: O objetivo deste estudo foi avaliar a associação da rigidez arterial, medida por tonometria de aplanação-Sphygmocor, com a CC. Métodos: Estudo observacional com 240 participantes que fazem consultas de rotina no ambulatório de clínica médica de um hospital universitário. Os participantes foram entrevistados e tiveram as medidas centrais da pressão arterial (MCPA), parâmetros antropométricos, gordura abdominal e gordura visceral mensurados. Foram u tilizados os testes t pareado e não pareado e qui-quadrado. Foi a dotado nível de significância de 5%. Resultados: Dos 240 participantes, 51,82% era do sexo masculino com idade média de 59,71(±14,81) anos e CC média de 99,87 (±11,54) cm. Os valores médios das MCPA foram: Pressão arterial central (PAC) = 130,23 (91-223) mmHg, velocidade de onda de pulso (VOP) = 9,8 (5,28-19,6)m/s e Augmentation Index [Índice de amplificação (AI)] = 29,45 (-14-60). A VOP e a PAC foram altamente correlacionadas com uma CC com p<0,001 e p=0,02, respectivamente; porém, a mesma correlação positiva não foi encontrada entre a CC e o AI (p=0,06). Conclusão: O presente estudo mostrou uma associação positiva entre a CC e a rigidez arterial, através da velocidade de onda de pulso carotídeo femoral (VOP-cf) e o AI, sendo mais forte com a VOP-cf, sugerindo a avaliação do efeito da CC na saúde vascular como método de auxílio no tratamento precoce das DCV e na prevenção de desfechos clínicos.

Abstract Background: Arterial stiffness is a strong predictor of cardiovascular disease (CVD). Body fat measures such as waist circumference (WC) have been associated with CVD in adulthood. Objectives: The objective of this study was to evaluate the association of arterial stiffness, measured by applanation tonometry-Sphygmocor, with WC. Methods: Observational study with 240 participants who make routine consultations at the outpatient clinic of a university hospital. Participants were interviewed and had central blood pressure measurements (CBPM), anthropometric parameters, abdominal fat and visceral fat measured. Paired and unpaired t and chi-square tests were used. A significance level of 5% was adopted. Results: Of the 240 participants, 51.82% were male with a mean age of 59.71(±14.81) years and a mean WC of 99.87 (11.54) cm. Mean CBPM values were: Central arterial pressure (CAP) = 130.23 (91-223) mmHg, pulse wave velocity (PWV) = 9.8 (5.28-19.6)m/s and Augmentation Index [Amplification Index (AI)] = 29.45 (-14-60). PWV and CAP were highly correlated with WC with p<0.001 and p=0.02, respectively; however, the same positive correlation was not found between WC and AI (p=0.06). Conclusion: The present study showed a positive association between WC and arterial stiffness, through the femoral carotid pulse wave velocity (cf-PWV) and AI, being stronger with cf-PWV, suggesting the evaluation of the effect of WC in vascular health as a method of aid in the early treatment of CVD and in the prevention of clinical outcomes.

Sinais de Injúria Cardíaca em Pacientes Pediátricos com COVID-19 Gravemente Enfermos: Uma Experiência de Centro Único no Brasil / Signs of Cardiac Injury in Critically Ill Paediatric Patients with COVID-19: a Single-Center Experience in Brazil

Resumo Fundamento Alguns pacientes com COVID-19 apresentam injúria miocárdica. Objetivo Detectar a injúria miocárdica em pacientes criticamente doentes, e comparar o envolvimento cardíaco entre crianças com síndrome respiratória aguda grave (SARS) e crianças com síndrome inflamatória multissistêmica (MIS-C). Métodos Todas as crianças acometidas da COVID-19 admitidas em uma unidade de terapia intensiva de referência foram cadastradas de forma prospectiva e fizeram uma ecografia transtorácica bidimensional (ETT-2D) e um teste de troponina I cardíaca (cTnI) nas primeiras 72 horas. Para a análise estatística, um p <0,05 bilateral foi considerado significativo. Resultados 33 pacientes foram incluídos, dos quais 51,5% apresentaram cTnI elevada e/ou ETT-2D anormal e 36,4% precisaram de suporte cardiovascular, que foi mais frequente em pacientes com cTnI elevada e anormalidades em ETT-2D do que em pacientes com exames normais (83,3% e 33,3%, respectivamente; p 0,006, 95% IC = 0,15-0,73). Os achados de ETT-2D mais comuns foram efusão pericárdica (15,2%) e regurgitação tricúspide/mitral (15,2%). Sinais de envolvimento cardíaco foram mais comuns na MIS-C que na SARS. Pacientes com MIS-C também apresentaram um índice mais alto de necessidade de suporte cardiovascular (66,7% X 25%, p 0,03, 95% IC = -0,7 a -0,04) e um índice mais frequente de cTnI elevada (77,8% X 20,8%; p 0,002, 95% IC = 0,19 a 0,79). Os valores preditivos negativos de cTnI para detecção de anormalidades de ETT-2D foram 100% para pacientes com MIS-C, e 73,7% para pacientes com SARS. Conclusão Sinais de injúria cardíaca foram comuns, especialmente em pacientes com MIS-C. As anormalidades na ETT-2D foram sutis. A realização de um teste de cTnI na admissão pode ajudar os prestadores de assistência de saúde a discriminar os pacientes com uma necessidade mais urgente de uma ETT-2D.

Abstract Background Some patients with COVID-19 present myocardial injury. Objective To detect myocardial injury in critically ill paediatric patients, and to compare cardiac involvement between children with severe acute respiratory syndrome (SARS) and children with multisystemic inflammatory syndrome (MIS-C). Methods All COVID-19 children admitted to a referral intensive care unit were prospectively enrolled and had a two-dimensional echocardiogram (2D-TTE) and a cardiac troponin I (cTnI) assay within the first 72 hours. For statistical analysis, two-sided p < 0.05 was considered significant. Results Thirty-three patients were included, of which 51.5% presented elevated cTnI and/or abnormal 2D-TTE and 36.4% needed cardiovascular support, which was more frequent in patients with both raised cTnI and 2D-TTE abnormalities than in patients with normal exams (83.3% and 33.3%, respectively; p 0.006, 95% CI = 0.15-0.73). The most common 2D-TTE findings were pericardial effusion (15.2%) and mitral/tricuspid regurgitation (15.2%). Signs of cardiac involvement were more common in MIS-C than in SARS. MIS-C patients also presented a higher rate of the need for cardiovascular support (66.7% vs 25%, p 0.03, 95% CI = -0.7 to -0.04) and a more frequent rate of raised cTnI (77.8% vs 20.8%; p 0.002, 95% CI = 0.19 to 0.79). The negative predictive values of cTnI for the detection of 2D-TTE abnormalities were 100% for MIS-C patients and 73.7% for SARS patients. Conclusion signs of cardiac injury were common, mainly in MIS-C patients. 2D-TTE abnormalities were subtle. To perform a cTnI assay upon admission might help providers to discriminate those patients with a more urgent need for a 2D-TTE.

O aproveitamento energético do gás gerado pela decomposição dos resíduos sólidos é um caminho atrativo para a solução, de uma só vez, desses dois problemas. Com objetivo de contribuir para o desenvolvimento da geração de energia elétrica a partir de aterros sanitários no Brasil, o presente trabalho compreende uma análise de potencial energético e de viabilidade financeira dessa alternativa energética no Brasil. Para a construção das análises, utilizaram-se dados de geração de resíduos e climáticos de seis cidades brasileiras, o que permitiu a estimativa da vazão de produção de gás nos aterros de cada uma dessas localidades, a potência ótima a ser instalada em cada um desses aterros e da viabilidade econômica dessa alternativa. Os valores de custo de geração obtidos variaram entre R$ 345 e 440·MWh, sendo fortemente influenciados por fatores como população, captação de resíduos e aspectos climáticos, sendo, em geral, superiores aos valores típicos de tarifa de venda de energia no país. Isso implica uma necessidade de formulação de políticas públicas de incentivo à geração de energia a partir de resíduos sólidos urbanos no Brasil.

ABSTRACT The search for alternative and renewable sources of energies is growing, as is the concern with the growing increase in the generation of waste by the world population. The energy use of the gas generated by the decomposition of solid waste at landfills is an attractive way to solve these two problems, at once. In order to contribute to the development of electric power generation from landfills in Brazil, the present work comprises an analysis of the energy potential and financial viability of this energy alternative in the country. For the construction of the analyses, waste and climate generation data from six Brazilian cities were used, which allowed the estimation of the gas production flow in the landfills of each city, the optimum power to be installed in each of these landfills and the economic viability of this alternative. The generation cost values obtained ranged between R$ 345 and 440·MWh, being strongly influenced by factors such as population, waste capitation and climatic factors, being, in general, higher than the typical values of energy sales tariff in the country. This implies a need to formulate public policies to encourage the generation of energy from solid urban waste in Brazil.

TGF-ß1 and CD68 immunoexpression in capsules formed by textured implants with and without mesh coverage: a study on female rats

Purpose: To evaluate fibrosis formation and number of macrophages in capsules formed around textured implants without and with mesh coverage. Methods: Fibrosis was analyzed through transforming growth factor-beta 1 (TGF-ß1) immunomarker expression and the number of macrophages through CD68 percentage of cells in magnified field. Sixty female Wistar rats were distributed into two groups of 30 rats (unmeshed and meshed). Each group was then subdivided into two subgroups for postoperative evaluation after 30 and 90 days. The p value was adjusted by Bonferroni lower than 0.012. Results: No difference was observed in fibrosis between meshed and unmeshed groups (30 days p = 0.436; 90 days p = 0.079) and from 30 to 90 days in the unmeshed group (p = 0.426). The meshed group showed higher fibrosis on the 90th day (p = 0.001). The number of macrophages was similar between groups without and with mesh coverage (30 days p = 0.218; 90 days p = 0.044), and similar between subgroups 30 and 90 days (unmeshed p = 0.085; meshed p = 0.059). Conclusions: In the meshed group, fibrosis formation was higher at 90 days and the mesh-covered implants produced capsules similar to microtextured ones when analyzing macrophages. Due to these characteristics, mesh coating did not seem to significantly affect the local fibrosis formation.

Wooden sticks for plaque streaking and microbiological inoculation might be more cost- effective, but is its large scale use feasible? Quality control methods and proof of concept / Métodos de controle de qualidade e prova de conceito para a utilização de palitos de madeira em microbiologia podem ser mais econômicas, mas seu uso em larga escala é viável? Método de controle de qualidade e prova de conceito

The loop is a material classically used in the laboratory for the purpose of plate streaking and handling biological materials. However, metal loops techniques might be time consuming, considering the amount of time spent to guarantee its cooling process through each inoculation. Furthermore, plastic loops may also represent environmental issues during its production and discard process and can also represent higher costs for the laboratory. Thus, in situations of limited resources, even the simplest materials can be restricted due to logistical and budgetary issues, especially in developing countries. Inspired by demands like these, facing an occasional shortage of supply of laboratory plastic handles, we hereby present a quality control for sterilization methods and cost-effectiveness studies towards the use of wooden sticks in a Latin American country and we discuss the possibility of the large-scale use of this technique.

A alça calibrada é um material usado classicamente em laboratório para fins de inoculação em placas e manuseio de materiais biológicos. No entanto, as técnicas de alças metálicas podem consumir muito tempo, considerando a quantidade de tempo gasto para garantir seu processo de resfriamento a cada inoculação. Além disso, alças de plástico também podem representar questões ambientais durante o processo de produção e descarte e também podem representar custos mais altos para o laboratório. Assim, em situações de recursos limitados, até os materiais mais simples podem ser restringidos devido a questões logísticas e orçamentárias, especialmente nos países em desenvolvimento. Inspirados por demandas como essas, diante de uma escassez ocasional de suprimentos de alças de plástico de laboratório, apresentamos um controle de qualidade para métodos de esterilização e estudos de custo-efetividade para o uso de varas de madeira em um país latino-americano e discutimos a possibilidade de grande uso em escala dessa técnica.

Impacto da pandemia da COVID-19 sobre transplantes de córnea / Impact of COVID-19 pandemic on corneal transplantations

RESUMO Objetivo: Tendo em vista que o sistema visual representa uma via de contaminação para o novo Corona vírus, a The Global Alliance of Eye Bank Association (GAEBA) divulgou um guideline preconizando a prevenção de transmissão do vírus entre o doadores de tecido ocular e o pacientes receptores, o que resultou em uma diminuição no número de ceratoplastias e aumento de filas de espera para transplantes de córnea (TC) em todo o mundo. Nesse sentido, o presente trabalho tem por objetivo analisar a situação do transplante de córnea (TC) no estado de Alagoas durante o primeiro ano de pandemia da COVID-19. Métodos: Trata-se de um estudo analítico, transversal, observacional utilizando dados provenientes de 3 fontes diferentes: Banco de Tecido Ocular Humano de Alagoas (BTO-AL), Registro Brasileiro de Transplantes (RBT) e Agência Nacional de Vigilância Sanitária (ANVISA). Resultados: Durante os últimos seis anos, foram realizados 284 TCs em Alagoas, segundo dados do Banco de Transplante de Olhos do estado (BTO), já segundo a Registro Brasileiro de Transplantes (RBT) foram realizados 451 TCs. A porcentagem de córneas não oriundas do BTO de Alagoas se mostrou crescente até 2019, porém decresceu em 2020, e no primeiro ano de pandemia , apenas 11,66% da necessidade anual estimada foi atendida, sendo o período com menor número de TCs realizados entre os seis anos analisados na pesquisa. Conclusão: O estudo demonstra o declínio na doação e realização de transplantes de córnea durante o primeiro ano da pandemia da COVID-19 em Alagoas.

ABSTRACT Objective: Considering the visual system is one source of contamination for the new coronavirus, The Global Alliance of Eye Bank Association (GAEBA) released a guideline recommending prevention of virus transmission between eye tissue donors and recipients, which resulted in a reduction of keratoplasties and increase in the waiting lists for corneal transplants worldwide. Hence, this work aims to analyze the situation of corneal transplantation in the state of Alagoas, during the first year of COVID-19 pandemic. Methods: This is an analytical, cross-sectional, observational study using data from 3 different sources: Human Eye Tissue Bank of Alagoas (BTO-AL), Brazilian Transplant Registry (RBT) and National Health Surveillance Agency (ANVISA). Results: During the past six years, 284 corneal transplants were performed in Alagoas, according to data from the Eye Transplant Bank (BTO) of the state, whereas according to the Brazilian Transplant Registry (RBT) 451 corneal transplants were performed. The percentage of corneas not coming from the BTO of Alagoas increased until 2019 but dropped in 2020. In the first year of the pandemic, only 11.66% of estimated annual need was met, and this period had the lowest number of corneal transplants performed out of the six years analyzed in the research. Conclusion: The study demonstrated the decline in donation and performance of corneal transplants during the first year of the COVID-19 pandemic in Alagoas.
