Controle químico de mancha azul e determinação de alguns de seus agentes causais em Araucaria angustifolia (Bert.) O. Ktze. reflorestada

Araucaria angustifolia (pinheiro-do-paraná) é susceptível ao ataque de fungos manchadores, o que desfavorece a comercialização de sua madeira no mercado nacional e internacional. Trabalhou-se num povoamento homogêneo dessa espécie florestal subdividido, desde a bordadura até o centro, em três faixas de largura igual, porém, transversais ao comprimento do mesmo. Abateram-se 36 árvores a cada mês, em 12 meses, transformando-as em toretes de 60cm de comprimento e diâmetro variável. Testaram-se três substâncias anti-manchais à base de sal de amônio quaternário, quelato de cobre e tribromofenol. Fez-se um tratamento paralelo, sem químicos, envolvendo as extremidades dos toretes com saco plástico e isolaram-se deles espécies de fungos. Trabalhou-se com duas épocas de umidade. Trataram-se os toretes, individualmente, por pulverização e distribuíram-se todos sobre o solo do povoamento em duas posições cardeais, usando-se três níveis de profundidade dentro do povoamento e expondo-os ao ambiente em seis períodos de tempo. Fizeram-se avaliações de todos os tratamentos nas seções transversal e axial de cada um dos 432 novos toretes, mensalmente, durante 12 meses. Concluiu-se, após análise estatística, que o TBP-90 (tribromofenol) e o Osmocobre AG-805 (quelato de cobre) controlaram a manqha azul, sendo mais eficientes na época menos úmida. O Armoblen 61 mostrou potencial como antimancha. Dos fungos isolados obtiveram-se as espécies mançhadoras Ceratocystis triangulospora (Butin) Upadhyay e Diplodia mutila Fr., bem como Microascus sp, não manchadora, porém ocorrendo juntamente com a primeira

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Cateter venoso profundo recoberto com antibiótico para reduzir infecção: estudo piloto Antibiotic coated catheter to decrease infection: pilot study

JUSTIFICATIVA E OBJETIVOS: A bacteremia associada a cateter venoso central (CVC) aumenta a morbidade e mortalidade hospitalar em pacientes internados em unidade de terapia intensiva (UTI). Os cateteres recobertos com rifampicina e minociclina (RM) reduzem a freqüência de colonização e bacteremia. No entanto, resultados de estudos recentes questionaram o seu impacto clínico. O objetivo deste estudo foi comparar a incidência de colonização e bacteremia associada à CVC recobertos com RM e não recobertos numa coorte de pacientes admitidos em UTI. METODO: Estudo prospectivo, controlado em UTI mista clínico-cirúrgica. Os pacientes receberam um CVC recobertos com RM ou não recoberto. Após remoção do CVC, foi feita cultura de ponta do cateter e hemoculturas foram coletadas. Avaliou-se a freqüência de colonização e bacteremia. RESULTADOS: Cento e vinte CVC foram inseridos e 100 puderam ser avaliados, 49 no grupo não recobertos e 51 no grupo recoberto. As características clínicas foram similares nos 2 grupos. Dois casos de bacteremia associada ao cateter (BAC) (3,9%) ocorreram em pacientes que receberam CVC recobertos com RM comparado a 5 (10,2%) casos de BAC no grupo não recobertos (p = 0,26). Seis (11,8%) cateteres recobertos foram colonizados, comparados a 14 (28,6%) no grupo não recoberto (p = 0,036). A análise de Kaplan-Meier não demonstrou diferença no risco de colonização ou BAC entre os dois grupos estudados. A taxa de BAC foi de 4,7 por 1000 cateteres-dia no grupo com CVC recobertos e 11,4 por 1000 cateteres-dia no grupo que recebeu cateteres não recobertos (p = 0,45). CONCLUSÕES: Neste estudo piloto, demonstrou-se menor freqüência de colonização em cateteres recobertos com RM, quando comparados a cateteres não recobertos. A freqüência de BAC não foi diferente entre os dois grupos.<br>BACKGROUND AND OBJECTIVES: Nosocomial catheter related bloodstream infections (CR-BSI) increase morbidity and mortality in critically ill patients. Central venous catheters (CVC) coated with rifampin and minocycline (RM) decrease rates of colonization and CR-BSI. However, recent trials challenged the clinical impact of such catheters. We designed this trial to compare rates of colonization and CR-BSI in RM catheters and controls in a cohort of critically ill patients in Brazil. METHODS: Prospective, controlled trial conducted in one medico-surgical ICU. Patients were assigned to receive a control or RM CVC. After removal, tips were cultured in association with blood cultures. Rates of colonization and CR-BSI were recorded. RESULTS: Among 120 catheters inserted, 100 could be evaluated, 49 in the uncoated and 51 in the coated group. Clinical characteristics of patients were similar in the two groups. Two cases of CR-BSI (3.9%) occurred in patients who received RM catheters compared with 5 (10.2%) in the uncoated group (p = 0.26). Six RM catheters (11.8%) were colonized compared with 14 (28.6%) control catheters (p = 0.036). Kaplan-Meier analysis showed no significant differences in the risk of colonization or CR-BSI. Rates of CR-BSI were 4.7 per 1000 catheter-days in the RM coated group compared to 11.4 per 1000 catheter days in the uncoated group (p = 0.45). CONCLUSIONS: In this pilot study, we showed lower rates of colonization in RM coated when compared with uncoated catheters. Incidence and rates of CR-BSI were similar in the two groups

Reduction of cardiac imaging tests during the COVID-19 pandemic: The case of Italy. Findings from the IAEA Non-invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Background: In early 2020, COVID-19 massively hit Italy, earlier and harder than any other European country. This caused a series of strict containment measures, aimed at blocking the spread of the pandemic. Healthcare delivery was also affected when resources were diverted towards care of COVID-19 patients, including intensive care wards. Aim of the study: The aim is assessing the impact of COVID-19 on cardiac imaging in Italy, compare to the Rest of Europe (RoE) and the World (RoW). Methods: A global survey was conducted in May–June 2020 worldwide, through a questionnaire distributed online. The survey covered three periods: March and April 2020, and March 2019. Data from 52 Italian centres, a subset of the 909 participating centres from 108 countries, were analyzed. Results: In Italy, volumes decreased by 67% in March 2020, compared to March 2019, as opposed to a significantly lower decrease (p &lt; 0.001) in RoE and RoW (41% and 40%, respectively). A further decrease from March 2020 to April 2020 summed up to 76% for the North, 77% for the Centre and 86% for the South. When compared to the RoE and RoW, this further decrease from March 2020 to April 2020 in Italy was significantly less (p = 0.005), most likely reflecting the earlier effects of the containment measures in Italy, taken earlier than anywhere else in the West. Conclusions: The COVID-19 pandemic massively hit Italy and caused a disruption of healthcare services, including cardiac imaging studies. This raises concern about the medium- and long-term consequences for the high number of patients who were denied timely diagnoses and the subsequent lifesaving therapies and procedures

Impact of COVID-19 on Diagnostic Cardiac Procedural Volume in Oceania: The IAEA Non-Invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Objectives: The INCAPS COVID Oceania study aimed to assess the impact caused by the COVID-19 pandemic on cardiac procedure volume provided in the Oceania region. Methods: A retrospective survey was performed comparing procedure volumes within March 2019 (pre-COVID-19) with April 2020 (during first wave of COVID-19 pandemic). Sixty-three (63) health care facilities within Oceania that perform cardiac diagnostic procedures were surveyed, including a mixture of metropolitan and regional, hospital and outpatient, public and private sites, and 846 facilities outside of Oceania. The percentage change in procedure volume was measured between March 2019 and April 2020, compared by test type and by facility. Results: In Oceania, the total cardiac diagnostic procedure volume was reduced by 52.2% from March 2019 to April 2020, compared to a reduction of 75.9% seen in the rest of the world (p&lt;0.001). Within Oceania sites, this reduction varied significantly between procedure types, but not between types of health care facility. All procedure types (other than stress cardiac magnetic resonance [CMR] and positron emission tomography [PET]) saw significant reductions in volume over this time period (p&lt;0.001). In Oceania, transthoracic echocardiography (TTE) decreased by 51.6%, transoesophageal echocardiography (TOE) by 74.0%, and stress tests by 65% overall, which was more pronounced for stress electrocardiograph (ECG) (81.8%) and stress echocardiography (76.7%) compared to stress single-photon emission computerised tomography (SPECT) (44.3%). Invasive coronary angiography decreased by 36.7% in Oceania. Conclusion: A significant reduction in cardiac diagnostic procedure volume was seen across all facility types in Oceania and was likely a function of recommendations from cardiac societies and directives from government to minimise spread of COVID-19 amongst patients and staff. Longer term evaluation is important to assess for negative patient outcomes which may relate to deferral of usual models of care within cardiology

International Impact of COVID-19 on the Diagnosis of Heart Disease

Background: The coronavirus disease 2019 (COVID-19) pandemic has adversely affected diagnosis and treatment of noncommunicable diseases. Its effects on delivery of diagnostic care for cardiovascular disease, which remains the leading cause of death worldwide, have not been quantified. Objectives: The study sought to assess COVID-19's impact on global cardiovascular diagnostic procedural volumes and safety practices. Methods: The International Atomic Energy Agency conducted a worldwide survey assessing alterations in cardiovascular procedure volumes and safety practices resulting from COVID-19. Noninvasive and invasive cardiac testing volumes were obtained from participating sites for March and April 2020 and compared with those from March 2019. Availability of personal protective equipment and pandemic-related testing practice changes were ascertained. Results: Surveys were submitted from 909 inpatient and outpatient centers performing cardiac diagnostic procedures, in 108 countries. Procedure volumes decreased 42% from March 2019 to March 2020, and 64% from March 2019 to April 2020. Transthoracic echocardiography decreased by 59%, transesophageal echocardiography 76%, and stress tests 78%, which varied between stress modalities. Coronary angiography (invasive or computed tomography) decreased 55% (p &lt; 0.001 for each procedure). In multivariable regression, significantly greater reduction in procedures occurred for centers in countries with lower gross domestic product. Location in a low-income and lower–middle-income country was associated with an additional 22% reduction in cardiac procedures and less availability of personal protective equipment and telehealth. Conclusions: COVID-19 was associated with a significant and abrupt reduction in cardiovascular diagnostic testing across the globe, especially affecting the world's economically challenged. Further study of cardiovascular outcomes and COVID-19–related changes in care delivery is warranted
