Gonioscopy-Assisted Transluminal Trabeculotomy Outcomes Under Different Levels of Glaucoma Severity: A Multicenter, Comparative Study.

PURPOSE: To evaluate the outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) under different levels of glaucoma severity. DESIGN: Retrospective, multicenter, before-and-after study. METHODS: One eye from all primary open-angle glaucoma patients who underwent GATT combined with cataract surgery (Phaco-GATT) or GATT stand-alone with 12 months of follow-up were included and divided according to glaucoma severity (mild = GI, moderate = GII, and advanced = GIII) and the outcomes compared. RESULTS: A total of 270 eyes were included: 90 in GI, 75 in GII, and 105 in GIII. The IOP was reduced from 18.6 ± 6.0 mm Hg in GI, 19.7 ± 6.4 mm Hg in GII, and 21.0 ± 7.9 mm Hg in GIII, preoperatively, to 11.9 ± 2.6 mm Hg in GI, 11.8 ± 2.1 mm Hg in GII, and 11.9 ± 3.0 mm Hg in GIII at 12 months postoperatively (P < .001 for all). The number of hypotensive ocular medications were reduced from 2.7 ± 1.0 in GI, 3.1 ± 0.8 in GII, and 3.2 ± 1.2 in GIII to 0.6 ± 0.9 in GI, 1.0 ± 1.1 in GII, and 1.2 ± 1.1 in GIII at the last postoperative visit (P < .001 for all). Relative success was achieved, at 1 year, in 93.8% of the eyes in GI, 89.0% in GII, and 88.1% in GIII (P = .3). Complete success was achieved in 61.8% of the eyes in GI, 43.8% in GII, and 37.6% in GIII (P = .007). No serious adverse event was observed in any group. CONCLUSIONS: GATT is a safe and effective procedure in glaucoma, regardless of its preoperative severity.

Benefits of using polymeric nanoparticles in breast cancer treatment: a systematic review.

Breast cancer comprises approximately 20% of all malignant neoplasm cases globally. Due to the limitations associated with conventional therapeutic approaches, extensive investigations have been undertaken to develop novel treatments that exhibit enhanced specificity and minimized adverse effects. Consequently, the application of polymeric nanoformulations for targeted drug delivery has gained significant attention within the biomedical field. Therefore, the primary objective of this study was to explore the inherent advantages and efficacy of employing polymeric nanoformulations for drug delivery in breast cancer treatment, as compared to traditional therapies. A comprehensive literature search was conducted across prominent databases including PubMed/MEDLINE, Embase, and Scopus, utilizing specific search strings. This meticulous approach yielded a total of 12 relevant articles for in-depth analysis and discussion. The findings from the selected studies underscore the effectiveness of employing polymeric nanoparticles as a drug delivery strategy, showcasing noteworthy improvements in cellular uptake and sustained intracellular retention of encapsulated therapeutic agents. Additionally, these nanoformulations exhibited superior efficacy, safety, and drug delivery capabilities. The utilization of polymeric nanoparticles in drug delivery has demonstrated a substantial enhancement in treatment efficacy, with the ability to achieve higher concentrations of active ingredients within tumor tissues, augment cellular uptake and drug concentrations, and sustain intracellular retention. Consequently, this innovative approach prolongs drug release in lower quantities, ultimately contributing to improved treatment outcomes.

Vagus Nerve Stimulation Electrode Impedance Over Time in Children With Lennox-Gastaut Syndrome.

OBJECTIVE: This manuscript describes the behavior of impedance of vagus nerve stimulation (VNS) electrode over time in a cohort of children with Lennox-Gastaut syndrome. MATERIALS AND METHODS: Nineteen consecutive pediatric patients with Lennox-Gastaut syndrome submitted to VNS were studied. All patients had at least four years of follow-up. Serial impedance measurements were carried out during every out-patient visit. A baseline value was obtained one month after surgery, before generator activation and yearly values were recorded for the next four years. Outcome regarding seizures was obtained through analysis of standardized seizure diaries filled out by the patient, relatives, or caregivers. RESULTS: There were 12 boys. Age ranged from four to 14 years (mean = 7.2). Mean impedance value was 2635 Ω at baseline, 2576 Ω after one year, 2418 Ω after two years, 2340 Ω after three years, and 2241 Ω after four years. There was a mean impedance decrease of 17% after four years. This decrease was statistically significant compared with baseline by the second year of follow-up: p = 0.342 after one year, p = 0.007 after two years, p = 0.001 after three years, and p = 0.001 after four years. There was no significant relationship between impedance values and seizure outcome at any time point. CONCLUSIONS: VNS electrode impedance significantly decreased during long-term follow-up in children with Lennox-Gastaut syndrome. To our knowledge, this is the first report on such findings regarding VNS in the literature. These findings suggest that the electrode/nerve interface is stable during long-term follow-up of VNS therapy and that this preserved anatomical relationship might be related to our ability to safely stimulate and review/explant the system whenever needed.

Effect of Systemic Insecticides Applied via Drench on the Mortality of Diaphorina citri on Curry Leaf.

Huanglongbing (HLB), the most serious disease in citriculture, is caused by the bacteria Candidatus Liberibacter spp., which is transmitted by the Asian citrus psyllid (ACP) Diaphorina citri. HLB is mainly controlled with insecticides, necessitating the development of alternative methods, e.g., the use of trap plants such as curry leaf Bergera koenigii, which is highly attractive to the ACP. We evaluated the effects of the main systemic insecticides used by citrus growers, applied via drench to adults of D. citri on the curry leaf tree. We tested the persistence of three pesticides: thiamethoxam, thiamethoxam + chlorantraniliprole, and imidacloprid in protected cultivation and the field condition at 7, 14, 28, 42, 56, 70, 98, and 154 days after the application. Different concentrations of insecticides containing the active ingredient thiamethoxam were tested on adults to determine the LC10 and LC50. Finally, we assessed the sublethal effects on the oviposition and development of D. citri. The insecticides controlled the adults for long periods. However, in the field experiment, from 42 days after application there was a decrease in mortality caused by pesticides applied via drench, while in the protected cultivation, mortality did not decline until the last day of evaluation. The median lethal concentration (LC50) for thiamethoxam was 0.031 g of active ingredient per plant, and for thiamethoxam in a mixture, the LC50 was 0.028 g a.i. per plant. In the experiment with sublethal doses, D. citri did not oviposit on the treated plants. Our findings suggest that the attract-and-kill system using the curry leaf tree and systemic insecticides is effective for the control of D. citri and contributes to the integrated management of HLB.

Overview of SARS-COV-2 infection at the Butantan Penitentiary Progression Center.

OBJECTIVE: To estimate the prevalence of exposure to the SARS-CoV-2 virus among individuals living in restricted freedom. METHODS: A seroprevalence survey was carried out with the population of the female penitentiary of the Centro de Progressão Penitenciária (CPP) in Butantan (municipality of São Paulo), between June 24 and August 20, 2020. During this period, according to the Secretariat of Penitentiary Administration (SAP), the positivity of rapid tests among inmates ranged from 65% to 78%. The evaluation method used in the study was the "One Step COVID-19" rapid test (chromatography), from the company Wondfo, also using the RT-PCR method in symptomatic participants to confirm the viral condition. The study population consisted of 879 female inmates and 170 employees of the institution. RESULTS: The prevalence of total antibodies (IgG/IgM) against the SARS-CoV-2 virus in the total population of 1049 study participants was 6.1%; among the population of 879 inmates,a prevalence of 5.8% was observed, and among the institution's employees, 7.5%. CONCLUSIONS: The prevalence of covid-19 at the Butantan CPP was low, which is due to the implementation of simple prevention measures at the institution, such as the use of masks (with appropriate changes), emphasis on hygiene, hand washing and social distancing, in addition to other strategies, such as suspending inmates' visits from relatives and friends and cutting back on elective medical appointments and outside work.

Comparison between selective head cooling and whole-body cooling in neonatal therapeutic hypothermia / Comparação entre resfriamento seletivo da cabeça e resfriamento de corpo inteiro na hipotermia terapêutica neonatal

INTRODUCTION: Experimental evidence, as well as improved clinical studies of the reduction of brain injury and, improves the neurological outcome, in newborns with hypoxic-ischemic encephalopathy (HIE) occurring in therapeutic hypothermia (TH). OBJECTIVE: To verify the potential of hypothermic hypoxic-ischemic encephalopathy (HIE) therapy in neonatal asphyxia, based on literature data, comparing the benefits between selective head cooling (SHC) and whole-body cooling (WBC), see that the use of TH as a standard treatment in newborns with moderate or severe HIE has been adopted. METHODS: A search was performed in the PubMed and SciELO databases of human studies, using the keywords "Therapeutic Hypothermia", "Induced Hypothermia", and "Hypoxic-Ischemic Encephalopathy", "Selective cooling of the head", "Total body cooling" and its variables. RESULTS: Eleven articles were selected to compose the review, after detailed reading. There is a consensus, that the reduction of the risk of death or disability at 18 months of life in neonates with moderate to severe HIE, occurs to TH through the techniques of WBC or SHC. It was found in the studies that there is no difference in terms of adverse effects between the two methods. As for radiological changes, such as hypoxic-ischemic injuries and the incidence of seizures after cooling, they are more frequent with SHC. CONCLUSION: Both WBC and SHC demonstrated neuroprotective properties, although WBC provides a broader area of brain protection. However, no significant differences were found between the methods in terms of adverse effects and beneficial short or long-term results.

INTRODUÇÃO: Evidências experimentais, assim como estudos clínicos, sugerem a redução da lesão cerebral e melhora do desfecho neurológico, em recém-nascidos com encefalopatia isquêmica hipóxica (EHI) submetidos à hipotermia terapêutica (HT). OBJETIVO: Verificar a potencialidade da terapia hipotérmica de encefalopatia hipóxico-isquêmica (EHI) na asfixia neonatal, com base em dados da literatura, comparando os benefícios entre o resfriamento seletivo da cabeça (RSC) e o resfriamento de corpo inteiro (RCI), visto que o uso de hipotermia terapêutica (HT) como tratamento padrão em recém-nascidos com EHI moderada ou grave tem sido amplamente adotada. MÉTODOS: Foi realizada uma busca nas bases de dados PubMed e SciELO de estudos em humanos, utilizando-se as palavras-chave "Therapeutic Hypothermia", "Induced Hypothermia", "Hypoxic-Ischemic Encephalopathy", "selective head cooling", "whole body cooling" e suas respectivas variáveis. RESULTADOS: Foram selecionados 11 artigos para compor a revisão, após leitura detalhada. É consenso, a redução do risco de morte ou incapacidade aos 18 meses de vida nos neonatos com EHI moderado a grave, submetidos à HT através das técnicas de RCI ou RSC. Constatou-se diante dos estudos que não há diferença em termos de efeitos adversos entre os dois métodos. Quanto às alterações radiológicas, as lesões hipóxico-isquêmicas e incidência de convulsões após o resfriamento são mais frequentes com o RSC. CONCLUSÃO: Tanto RCI quanto o RSC demonstraram propriedades neuroprotetoras, embora o RCI proporcione uma área de proteção cerebral mais ampla. No entanto, não foram constatadas diferenças significativas entre os métodos quanto a efeitos adversos e a resultados benéficos em curto e longo prazo.

RESUMO OBJETIVO Estimar a prevalência da exposição ao vírus SARS-CoV-2 entre indivíduos vivendo em restrição de liberdade. MÉTODOS Foi realizado inquérito de soroprevalência com a população da penitenciária feminina do Centro de Progressão Penitenciária (CPP) do Butantan (município de São Paulo), entre 24 de junho e 20 de agosto de 2020. Nesse período, segundo a Secretaria de Administração Penitenciária (SAP), a positividade dos testes rápidos entre detentos variou de 65 a 78%. O método de avaliação utilizado no estudo foi o teste rápido "One Step COVID-19" (cromatografia), da empresa Wondfo, empregando-se também o método RT-PCR em participantes sintomáticos para confirmação do quadro viral. A população do estudo foi constituída por 879 reeducandas e 170 funcionários da instituição. RESULTADOS A prevalência de anticorpos totais (IgG/IgM) contra o vírus SARS-CoV-2 na população total de 1.049 participantes do estudo foi de 6,1%; entre a população de 879 reeducandas foi observada prevalência de 5,8% e entre os servidores da instituição, 7,5%. CONCLUSÃO Houve baixa prevalência de covid-19 no CPP do Butantan, o que se deve à implementação de medidas de prevenção simples na instituição, como o uso de máscaras (com trocas adequadas), ênfase na higiene, lavagem das mãos e distanciamento social, além de outras estratégias, como suspensão de visitas de familiares e amigos das reeducandas, cortes de consultas médicas eletivas e do trabalho externo.

Using Surrogate Insects in Acid Bioassays for Development of New Controls for Varroa destructor (Arachnida: Varroidae).

Resistance to traditional synthetic compounds by Varroa destructor Anderson and Trueman and shortcomings of the organic acid class of acaracides commonly used in varroa management requires continual development of new controls. V. destructor, however, are difficult to obtain for use in control bioassays because they are obligate parasites that cannot be easily reared outside of a honey bee colony. We conducted bioassays using other, more easily obtainable species to find organisms that could be used as surrogates for V. destructor when testing new potential controls. We compared the toxicities of acetic acid, lactic acid, formic acid, and oxalic acid at 0.005%, 0.05%, 0.5%, 5%, and 50% (20% oxalic acid only) concentrations based on natural volatility (nonheated) for the control of two beetle species, Oryzaephilus surinamensis L. and Alphitobius diaperinus Panzer, greater wax moth larvae, Galleria mellonella L., and V. destructor. The assay results were consistent across all species with formic acid and acetic acid showing 100% mortality of all four test species at 50% concentration. The assays also provided insight into the method of application (vaporization or contact) needed to cause mortality. Our results show that other organisms can be used in place of V. destructor for initial testing of acids and possibly other chemicals for control of the ectoparasite.

Detection of SARS-CoV-2 virus via dynamic light scattering using antibody-gold nanoparticle bioconjugates against viral spike protein.

Mass testing for the diagnosis of COVID-19 has been hampered in many countries owing to the high cost of genetic material detection. This study reports on a low-cost immunoassay for detecting SARS-CoV-2 within 30 min using dynamic light scattering (DLS). The immunosensor comprises 50-nm gold nanoparticles (AuNPs) functionalized with antibodies against SARS-CoV-2 spike glycoprotein, whose bioconjugation was confirmed using transmission electron microscopy (TEM), UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), and surface-enhanced Raman scattering spectroscopy (SERS). The specific binding of the bioconjugates to the spike protein led to an increase in bioconjugate size, with a limit of detection (LOD) 5.29 × 103 TCID50/mL (Tissue Culture Infectious Dose). The immunosensor was also proven to be selective upon interaction with influenza viruses once no increase in size was observed after DLS measurement. The strategy proposed here aimed to use antibodies conjugated to AuNPs as a generic platform that can be extended to other detection principles, enabling technologies for low-cost mass testing for COVID-19.

Women engaged in prostitution and COVID-19: why are they excluded from socially vulnerable groups?

This study analyzed the exposure of women engaged in prostitution in downtown São Paulo to COVID-19. This cross-sectional study had a convenience sample selected in May 2021. We interviewed 219, mostly black, middle-aged, poor women with comorbidities. Among them, 61 had shown COVID-19 symptoms, 23, tested positive for the disease, seven underwent hospitalization, and four reported post-COVID-19 complications. Only 26 (30.2%) had been vaccinated. In addition to gender, race, and class inequalities, these women suffer both from a higher risk of contracting COVID-19 due to their working conditions and from the subsequent worsening of that disease due to age and lack of vaccination.

Mulheres profissionais da saúde e as repercussões da pandemia da Covid-19: é mais difícil para elas? / Female health care professionals and repercussions of the Covid-19 pandemics: is it harder for them?

RESUMO A pandemia da Covid-19 promoveu mudanças significativas no cotidiano de todos, mas entre os profissionais da saúde, estas foram ainda mais profundas. A crise sanitária impactou relações pessoais, sociais e familiares, trazendo sensação de desamparo e insegurança, agravadas ainda pelo desastroso enfrentamento da pandemia pelo governo federal no Brasil. A força de trabalho na saúde tem sido apontada pela literatura como majoritariamente feminina e o papel social de gênero, somado ao contexto atual, agrava as implicações da pandemia para as mulheres. Este estudo analisou as repercussões da pandemia da Covid-19 sobre diferentes perfis de profissionais da saúde no estado de São Paulo. Estudo descritivo, utilizou questionário semiestruturado, on-line validado e o processamento dos dados quantitativos foi realizado pelo software Stata 13.0. Foram comparadas as respostas de acordo com o gênero declarado. Os achados corroboram com a literatura acerca da prevalência importante de sobrecarga de profissionais da saúde, e da discrepância entre fatores de sobrecarga apontados por gênero. A sobrecarga doméstica foi mais presente entre mulheres, reforçando que estas são afetadas de maneira desigual. Essa situação fragiliza a saúde mental, traz alterações no humor, sono, cognição, ansiedade, desconforto físico e pessimismo. Os resultados reforçam a necessidade de um olhar de gênero para as ações e respostas às consequências que surgirão à medida que a pandemia avança e na recuperação da sociedade no pós-pandemia.

ABSTRACT The Covid-19 pandemic promoted significant changes in everyone's daily lives, but among health professionals, those were even more profound. It impacted personal, social and family relationships, bringing feelings of helplessness and insecurity, aggravated by the disastrous confrontation of the pandemic by the Federal Government in Brazil. The health workforce has been identified in the literature as mostly female. The social role of gender, added to the current context, aggravates the implications of the pandemic for women. This study analyzed the repercussions of the Covid-19 pandemic on different profiles of health professionals in the State of São Paulo. This is a descriptive study which used a semi-structured, online, validated questionnaire. The processing of quantitative data was made using Stata 13.0 software. Answers were compared according to the declared gender. The findings corroborate the literature on the prevalence of significant burden on health professionals and the discrepancy between burden factors identified by gender. Household overload was more present among women, reinforcing that they are unevenly affected. This situation weakens mental health, brings changes in mood, sleep, cognition, anxiety, physical discomfort, and pessimism. Our results reinforce the need for a gender perspective in actions and responses to the consequences that will arise as the pandemic advances and in the recovery of society in the post-pandemic period.

Domínios de competências essenciais nas práticas colaborativas em equipe interprofissional: revisão integrativa da literatura / Core competency domains in the collaborative practices of interprofessional health teams: an integrative literature review / Dominios de competencias esenciales en las prácticas colaborativas en equipo interprofesional: revisión integradora de la literatura

O objetivo desta pesquisa foi sintetizar evidências das práticas colaborativas interprofissionais segundo os domínios de competências essenciais do Canadian Interprofessional Health Collaborative (CIHC). Foi conduzida revisão integrativa da literatura, dos últimos dez anos, nas bases Pubmed, Web of Science e Biblioteca Virtual em Saúde e síntese das práticas segundo a estrutura proposta pela CIHC. Dos 364 artigos selecionados, 21 foram incluídos com amostras entre 12 e 972 participantes; 11 estudos utilizaram instrumentos para avaliação das práticas; 43% evidenciaram os seis domínios essenciais; e 38%, de três a quatro. A resolução de conflitos interprofissionais não foi abordada em 48% dos artigos. Foi observada a adesão aos domínios de competências essenciais, o que tende a qualificar o processo de trabalho. Entretanto, a lacuna observada na abordagem do enfrentamento dos conflitos interprofissionais representa um obstáculo para vencer a formação uniprofissional. (AU)

The aim of this study was to synthesize evidence of collaborative practices based on the core competency domains proposed by the Canadian Interprofessional Health Collaborative (CIHC). We conducted an integrative literature review of articles published over the last 10 years. Searches were performed of the PubMed, Web of Science and Virtual Health Library databases and a synthesis of the practices based on the framework proposed by the CIHC. The search yielded 364 articles, 21 of which were included in the sample. The included studies used samples of between 12 and 972 participants. Eleven of the studies used practice assessment instruments; 43% included all six core competency domains and 38% included three to four. Forty-eight per cent of the studies did not address interprofessional conflict resolution. The findings demonstrate that adherence to the core competency domains tends to improve the quality of work process. However, the gap represented by the failure to address interprofessional conflict resolution is an obstacle to overcoming uniprofessional training. (AU)

Association of inflammatory and coagulation biomarkers with mortality in patients aged 60 years or older and hospitalized with COVID-19 / Associação entre biomarcadores inflamatórios e da coagulação com mortalidade em pacientes com 60 anos de idade ou mais hospitalizados com COVID-19

Objectives: To analyze the association of inflammatory and coagulation biomarkers with mortality in geriatric patients with COVID-19. Methods: This is a retrospective cohort study of 206 patients aged 60 years or older who were hospitalized with COVID-19 at an intensive care unit. The analyzed variables were age, sex, length of hospital stay, and inflammatory biomarkers (C-reactive protein, neutrophil-to-lymphocyte ratio, procalcitonin, fibrinogen, ferritin, and d-dimer). We constructed a receiver operating characteristic curve and analyzed the area under the curve to evaluate the accuracy of biomarkers associated with mortality in patients with COVID-19. Results: Mean age was 72 (± 8) years. There were 101 deaths (49% of the total sample), which were significantly more frequent (p = 0.006) in the older age groups and were distributed as follows: 37.50% (60 ­ 69 years old); 50% (70 ­ 79 years old); 67.50% (80 ­ 89 years old); and 75% (over 90 years old). Mortality was associated with increased serum levels of procalcitonin, neutrophil-to-lymphocyte ratio, C-reactive protein, and d-dimer, and decreased fibrinogen levels. Neutrophil-to-lymphocyte ratio occupied the largest area under the receiver operating characteristic curve (area under the curve 0.859) in this group. Conclusions: In this study, inflammatory biomarkers neutrophil-to-lymphocyte ratio, procalcitonin, C-reactive protein, and d-dimer were associated with mortality in older patients with COVID-19 hospitalized at an intensive care unit, and neutrophil-to-lymphocyte ratio presented the best accuracy.

Objetivos: Analisar associação de biomarcadores inflamatórios e da coagulação com mortalidade em pacientes geriátricos com COVID-19. Metodologia: Estudo do tipo coorte retrospectiva de 206 pacientes com 60 anos de idade ou mais internados em unidade de terapia intensiva (UTI) com COVID-19. As variáveis analisadas foram idade, sexo, tempo de permanência hospitalar e biomarcadores inflamatórios, sendo esses proteína C reativa (PCR), relação neutrófilo-linfócitos (RNL), procalcitonina, fibrinogênio, ferritina e D-dímero. Empregou-se a curva ROC, com análise da área sob a curva (ACR), para avaliar a acurácia dos biomarcadores associados à mortalidade nos pacientes com COVID-19. Resultados: A média de idade foi de 72 (± 8) anos. Ocorreram 101 óbitos (49,02% da amostra total), significativamente mais frequente (p = 0,006) nas faixas etárias mais elevadas, distribuídos por faixa etária: 37,50% (60 ­ 69 anos); 50% (70 ­ 79 anos); 67,50% (80 ­ 89 anos); e 75% (nos maiores de 90 anos). A mortalidade foi associada a aumento dos níveis séricos dos biomarcadores procalcitonina, relação neutrófiloslinfócitos (RNL), proteína C reativa (PCR) e D-dímero, bem como diminuição dos níveis de fibrinogênio. A RNL ocupou a maior área sob a curva ROC (ACR 0,859) nesse grupo. Conclusões: Neste estudo, os biomarcadores inflamatórios RNL, procalcitonina, PCR e D-dímero foram associados com mortalidade em pacientes idosos portadores de COVID-19 internados em UTI, e a RNL foi a que apresentou a melhor acurácia.

RESUMO Esta pesquisa analisou a exposição de mulheres em situação de prostituição no centro de São Paulo à covid-19. Este estudo transversal contou com amostra de conveniência selecionada em maio de 2021. Entrevistou-se 219 mulheres majoritariamente negras, de meia idade, pobres e com comorbidades. Dentre essas mulheres, 61 tiveram sintomas de covid-19, 23 com teste positivo,7 foram internadas e 4 relataram complicações pós-covid-19. Somente 26 (30,2%) haviam sido vacinadas. Além das desigualdades de gênero, raça e classe, essas mulheres são expostas a um maior risco de contraírem covid-19, devido às condições de trabalho e por apresentarem doença grave relacionada à idade e falta de vacinação.

Risk Assessment of Insecticides Used in Tomato to Control Whitefly on the Predator Macrolophus basicornis (Hemiptera: Miridae).

The generalist mirid predator Macrolophus basicornis may contribute to Integrated Pest Management (IPM) of Bemisia tabaci in tomato crops. It is important to know the compatibility of the chemicals used to control this pest with this promising biological control agent. Seven insecticides were tested to investigate their toxicity to the predator. For four of the products, the LC50 for adults were determined. Buprofezin, cyantraniliprole and spiromesifen did not cause lethality and were classified as harmless. Acetamiprid, bifenthrin, etofenprox + acetamiprid and pyriproxyfen + acetamiprid caused acute toxicity and were classified as harmful. LT50 for all harmful insecticides were relatively low, ranging from 1.8 to 3.2 days. Moreover, these four insecticides have low LC50, with acetamiprid (0.26 mg a.i. L-1) as the lowest, followed by bifenthrin (0.38 mg a.i. L-1), etofenprox + acetamiprid (4.80 mg a.i. L-1) and pyriproxyfen + acetamiprid (8.71 mg a.i. L-1). However, the calculated risk quotient (RQ) values demonstrated that these insecticides were mostly ecologically safe for this predator, except for acetamiprid, classified as slightly to moderately toxic. The present study can contribute to the use of M. basicornis as a biological control agent on tomato crops and to compatible use with the insecticides tested, according to IPM strategies.

Performance of the quantification of adenosine deaminase and determination of the lactate dehydrogenase/adenosine deaminase ratio for the diagnosis of pleural tuberculosis in children and adolescents.

OBJECTIVE: To evaluate the accuracy of determining the adenosine deaminase (ADA) level, the 2'-deoxyadenosine/ADA ratio, and the LDH/ADA ratio in pleural fluid for the diagnosis of pleural tuberculosis (PT) in children and adolescents. METHODS: This was a retrospective cross-sectional study conducted at a tertiary hospital in a high-tuberculosis-incidence area, between 2001 and 2018. All patients with ADA in pleural fluid and a confirmed diagnosis of PT (cPT) or parapneumonic effusion (PPE) were included. RESULTS: The cPT and PPE groups comprised 25 and 68 individuals, respectively. At a cutoff of 40 U/L, ADA measurement showed the following: sensitivity, 88%; specificity, 31%; positive predictive value (PPV), 32%; negative predictive value (NPV), 88%; and overall accuracy, 46%. The best cutoffs were an ADA level of 125 U/L, a 2'-deoxyadenosine/ADA ratio of 0.5, and an LDH/ADA ratio of 8.3, with AUC of 0.67, 0.75, and 0.82, respectively. The sensitivity, specificity, PPV, NPV, and overall accuracy of the 125 U/L ADA cutoff were 84%, 65%, 47%, 92%, and 70%, respectively, compared with 79%, 79%, 59%, 91%, and 79%, respectively, for the 8.3 LDH/ADA ratio cutoff. Changing the LDH/ADA ratio cutoff to 3.0 increased the specificity to 98%. CONCLUSIONS: The ADA level and the 2'-deoxyadenosine/ADA ratio are not good biomarkers for the diagnosis of PT in pediatric patients. Determination of the LDH/ADA ratio provides the best overall accuracy for the diagnosis of PT in such patients.
