Abstract: En Pt

The publication Cardiovascular Statistics – Brazil aims to provide an annual compilation of data and research on the epidemiology of CVDs in Brazil.  The report integrates official statistics from the Brazilian Ministry of Health and other governmental entities alongside data from the GBD project, coordinated by the IHME at the University of Washington. Additionally, it incorporates data derived from various sources and scientific studies, including cohorts and registries, that relate to CVDs and their associated risk factors. This publication is intended for a wide range of individuals, including researchers, clinicians, patients, healthcare policymakers, media professionals, the general public, and other interested parties seeking extensive national data about heart disease and stroke.  Volunteer researchers from various Brazilian universities and research institutions carry out the project. The group is led by a five-member steering committee (ALPR, CAP, DCM, GMMO, and LCCB). The Brazilian Society of Cardiology fully supports this initiative, and the project receives collaborative support from the GBD Brazil Network and an International Committee (GAR, PP, and TAG) from both the IHME/University of Washington (GAR) and the World Heart Federation (PP and TAG).

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Abstract: En | Text: En | PDF: En

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

ABSTRACT This study investigated the potential of Bacillus thuringiensis isolates obtained in the Cerrado region of the Brazilian state of Maranhão for the biological control of Aedes aegypti larvae. The isolates were obtained from soil samples and the identification of the B. thuringiensis colonies was based on morphological characteristics. Bioassays were run to assess the pathogenicity and toxicity of the different strains of the B. thuringiensis against third-instar larvae of A. aegypti. Protein profiles were obtained by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Polymerase chain reaction assays were used to detect the toxin genes found in the bacterial isolates. Overall, 12 (4.0%) of the 300 isolates obtained from 45 soil samples were found to present larvicidal activity, with the BtMA-104, BtMA-401 and BtMA-560 isolates causing 100% of mortality. The BtMA-401 isolate was the most virulent, with the lowest median lethal concentration (LC50) (0.004 × 107 spores/mL), followed by the Bacillus thuringiensis var. israelensis standard (0.32 × 107 spores/mL). The protein profiles of BtMA-25 and BtMA-401 isolates indicated the presence of molecular mass consistent with the presence of the proteins Cry4Aa, Cry11Aa and Cyt1, similar to the profile of Bacillus thuringiensis var. israelensis IPS-82. Surprisingly, however, none of the cry and cyt genes analyzed were amplified in the isolate BtMA-401. The results of the present study revealed the larvicidal potential of B. thuringiensis isolates found in the soils of the Cerrado region from Maranhão, although further research will be necessary to better elucidate and describe other genes associated with the production of insecticidal toxins in these isolates.

We investigated the use of Bacillus thuringiensis isolated in the state of Amazonas, in Brazil, for the biological control of the dengue vector Aedes aegypti. From 25 soil samples collected in nine municipalities, 484 bacterial colonies were obtained, 57 (11.78%) of which were identified as B. thuringiensis. Six isolates, IBt-03, IBt-06, IBt-07, IBt-28, IBt-30, and BtAM-27 showed insecticidal activity, and only BtAM-27 presents the five genes investigated cry4Aa, cry4Ba, cry10Aa, cry11Aa, and cry11Ba. The IBt-07 and IBt- 28, with lower LC50 values, showed equal toxicity compared to the standards. The isolates of B. thuringiensisfrom Amazonas constitute potential new means of biological control for A. aegypti, because of their larvicidal activity and the possibility that they may also contain new combinations of toxins.

Trichogramma spp. (Hymenoptera: Trichogrammatidae) can control Diaphania hyalinata Linnaeus (Lepidoptera: Pyralidae). On the other hand, pesticides may reduce the efficiency of natural enemies. The objective was to evaluate the side-effects of fungicides used in the production of cucurbitaceous crops on Trichogramma atopovirilia Oatman & Platner parasitizing D. hyalinata eggs. The fungicides used in bioassays were: azoxystrobin (0.08 g active ingredient [ai] L-1), chlorothalonil (2.00 g ai L-1), mancozeb (1.60 g ai L-1), tebuconazole (0.25 g ai L-1) and thiophanate-methyl (0.49 g ai L-1). Cardboards with 30 D. hyalinata eggs previously immersedin fungicide solutions and distilled water (control) were offered separately to 20 newly emerged T. atopovirilia females in glass tubes. Parasitism, parasitism reduction, emergence, sex ratio, and number of individuals per egg were evaluated. The fungicides chlorothalonil, thiophanate-methyl and tebuconazole reduced parasitism of T. atopovirilia by 43.37, 27.64 and 18.51%, respectively. However, parasitism with azoxystrobin (79.21%) was higher than the control (67.37%) (P ≤ 0.05). Chlorothalonil, thiophanate-methyl and tebuconazole reduced emergence by 73.77, 75.62 and 79.35% (P ≤ 0.05), respectively. Azoxystrobin and thiophanate-methyl reduced the sex ratio by 0.77 and 0.76 (P ≤ 0.05), respectively. Fungicides did not reduce the number of individuals per egg. The fungicides azoxystrobin and mancozeb were selective for T. atopovirilia for most studied parameters suggesting that these products must have the priority in crop disease management to allow efficient biological control of T. atopovirilia against D. hyalinata.

Trichogramma spp. (Hymenoptera: Trichogrammatidae) pueden controlar Diaphania hyalinata Linnaeus (Lepidoptera: Pyralidae). Sin embargo, los plaguicidas pueden reducir la eficiencia de los enemigos naturales. El objetivo de este trabajo fue evaluar la influencia de los fungicidas utilizados en la producción de cucurbitáceas en Trichogramma atopovirilia Oatman & Platner sobre huevos de D. hyalinata. Se evaluaron los fungicidas azoxystrobina (0.08 g ingrediente activo [ia] L-1), clorotalonil (2.00 g ia L-1), mancozeb (1.60 g ia L-1), tebuconazole (0.25 g ia L-1) and tiofanato-metil (0.49 g ia L-1). Tarjetas con 30 huevos de D. hyalinata previamente sumergidos en los fungicidas y en agua destilada (control) fueron ofrecidas a 20 hembras de T. atopovirilia con hasta 24 h de emergencia individualizadas en tubos de vidrio. Se evaluó parasitismo, reducción de parasitismo, emergencia, proporción sexual en la población y el número de individuos emergidos por huevo. Los fungicidas clorotalonil, tiofanato-metil y tebuconazol redujeron el parasitismo de T. atopovirilia en 43,37; 27,64 y 18,51%, respectivamente. Sin embargo, el parasitismo con azoxistrobina (79,21%) fue mayor que el control (67,37%) (P ≤ 0,05). Clorotalonil, tiofanato-metilo y el tebuconazol redujo la aparición de 73,77, 75,62 y 79,35% (P ≤ 0,05), respectivamente. Azoxistrobina y tiofanato-metil reduciran la proporción de sexos de 0,77 y 0,76 (P ≤ 0,05), respectivamente. Ninguno de los fungicidas redujo el número de individuos por cada huevo. Los fungicidas azoxistrobina y mancozeb fueron selectivos para T. atopovirilia en la mayoría de los parámetros estudiados, por lo tanto, deberían tener prioridad en el manejo de enfermedades de cucurbitáceas para permitir el uso eficiente de los enemigos naturales de D. hyalinata.

The objective of this work was to evaluate information about biological characteristics of egg of parasitoid Trichogramma exiguum Pinto & Platiner, (Hymenoptera: Trichogrammatidae) on the alternative hosts Anagasta kuehniella Zeller (Lepidoptera: Pyralidae) and Sitotroga cerealella Oliver (Lepidoptera: Gelechiidae) aiming to use in biological control programs. The higher rate of parasitism of the T. exiguum was verified on eggs of A. kuehniella. The viability of eggs was higher on eggs of S. cerealella. There is not influence in both alternative hosts in the sex ratio. Both alternative hosts can be used in massal rearing of T. exiguum, however due to the importance of the rate of parasitism, A. kuehniella is better adapting.

O objetivo deste trabalho foi obter informações sobre alguns aspectos biológicos de Trichogramma exiguum Pinto & Platiner, (Hymenoptera: Trichogrammatidae) criado nos hospedeiros alternativos Anagasta kuehniella Zeller (Lepidoptera: Pyralidae) e Sitotroga cerealella Oliver (Lepidoptera: Gelechiidae), visando à produção desses parasitóides para utilização no controle biológico de pragas. A maior taxa de parasitismo de T. exiguum foi encontrada em ovos de A. kuehniella. A viabilidade foi superior em ovos de S. cerealella. A razão sexual foi semelhante para ambos os hospedeiros alternativos. Estes resultados demonstram que ambos hospedeiros alternativos podem ser utilizados na criação massal de T. exiguum, porém levando em consideração a importância da taxa de parasitismo, A. kuehniella demonstrou maior aptidão.

Foi estudada a capacidade de parasitismo de Trichogramma acacioi em ovos de Anagasta kuehniella e Sitotroga cerealella em diferentes temperaturas (15, 20, 25, 30 e 35 ± 1°C). O parasitismo de T. acacioi variou com a temperatura e hospedeiro. O maior parasitismo (³80%) foi observado durante os primeiros dias após a emergência, em ambos hospedeiros e em todas as temperaturas estudadas. O parasitismo acumulado variou nas diferentes temperaturas e hospedeiros, sendo maior em A. kuehniella a 20ºC, o que mostra uma boa adaptação da espécie do parasitóide a essa temperatura. Assim, concluímos que o melhor hospedeiro alternativo e melhor temperatura para serem usadas em criações massais de T. acacioi é a A. kuehniella e 20ºC, respectivamente. Ainda, esta espécie de Trichogramma tem grande potencial para ser usada em liberações de campo em regiões onde a temperatura média está em torno de 20ºC.

It was studied the parasitism capacity of Trichogramma acacioi on Anagasta kuehniella and Sitotroga cerealella eggs at different temperatures (15, 20, 25, 30 and 35 ± 1°C). The parasitism of T. acacioi varied with temperature and host. The highest parasitism (³80%) were observed during the first days after emergence in both hosts, at all tested temperatures. The accumulated parasitism varied with both host and temperature, being higher on A. kuehniella at 20°C, what shows good parasitoid species adaptation to this temperature. Thus, we conclude that the best host and best temperature to be used at mass-rearing of T. acacioi is A. kuehniella and 20ºC, respectively. Moreover, this Trichogramma species has great potential to be used in field releases at regions where average temperature is around 20ºC.

Aspectos biológicos de Diaphania hyalinata L. foram estudados quando as lagartas foram criadas em dietas natural e artificial em condições de laboratório, a 25 ± 1ºC, umidade relativa de 70 ± 10% e fotofase de 14h. Como dieta natural foi utilizada abóbora jacaré, pepino e abobrinha caserda e uma dieta artificial utilizada em criações de Diatraea saccharalis (Fabr.), desenvolvida por Hensley & Hammond. As lagartas de D. hyalinata foram colocadas nos diferentes substratos e criadas por todo o ciclo. Observaram-se diferenças na duração do período larval, sobrevivência das larvas e pupas, longevidade do adulto e número de ovos entre os substratos. A dieta artificial a que mostrou de modo geral, mais adequada para a criação de D. hyalinata. Entre as dietas naturais, o pepino foi o que se apresentou mais adequado para criação desta praga.

The aim of this research was to evaluate the biological behaviour of melonworm at different natural and artificial diets. Squash cultivar jacaré, cucumber, summer squash and an artificial diets developed by Hensley & Hammond for the sugarcane borer were tried. The research was carried out in the Laboratório de Entomologia do Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, in climatized room at 25 ± 1ºC, relative humidity of 70 ± 10% and 14h photofase. The caterpillars fed on each substrate during the whole life cycle. Differences in duration of the larval period, larvae and pupae survival, adult longevity and number of eggs were registered between the substrates. The results show that the best diet for rearing is the artificial one. Between the natural diets the cucumber showed the best results.

Visando averiguar a presença de parasitóides do gênero Trichogramma, para utilização no controle biológico de pragas na cultura do feijão-vagem, foram coletadas posturas de Urbanus proteus (L.) que apresentavam ovos com características de parasitismo (ovos escuros). Os ovos foram encaminhados ao laboratório, onde se observou 44,9% de parasitismo. Constatou-se a viabilidade de 96.3%, com a média de 6,6 indivíduos por ovo e razão sexual de 0,93. Espécimes machos foram identificados, mostrando tratar-se de Trichogramma bruni Nagaraja, espécie que até então não havia sido descrita nesse hospedeiro e cultura.

Aiming to verify the presence of eggs parasitoids of the genus Trichogramma, for using in the biological control of insects pests, were collected eggs from long tailed skipper butterfly, a lepidopteran defoliator of snap beans, which presented eggs with parasitism characteristics (dark eggs). The eggs were taken to the laboratory were 44.9% of parasitism was verified. Viability was 96.3%, with an average of 6.6 individuals per egg and a sexual ratio of 0.93. Male specimens were identified as Trichogramma bruni Nagaraja. It is the first report of parasitism in this host and culture.

A biologia de Trichogramma atopovirilia Oatman & Platner parasitando ovos de Diaphania hyalinata L. foi estudada nas temperaturas de 18, 21, 24, 27, 30 e 33ºC e suas exigências térmicas foram determinadas. Trinta ovos do hospedeiro foram submetidos ao parasitismo na proporção de uma fêmea do parasitóide para 10 ovos, durante 5h, a 25°C e incubados nas diferentes temperaturas. Os parâmetros avaliados foram duração do ciclo ovo-adulto, viabilidade, número de indivíduos emergidos por ovo e razão sexual. A duração do período de desenvolvimento ovo-adulto apresentou relação inversa à temperatura e foi de 24,12 dias a 18°C e 7,36 dias a 33°C. A viabilidade do parasitismo a 24, 27 e 30ºC foi superior a 90%. O número de indivíduos emergidos por ovo hospedeiro e a razão sexual não sofreram influência da temperatura. A temperatura base (Tb) e a constante térmica (K) requerida por T. atopovirilia criados em ovos de D. hyalinata foi de 11,99°C e 130,42°C, respectivamente. Baseado nas médias térmicas de duas localidades de cultivo de cucurbitáceas da Bahia (Rio Real e Inhambupe) estimou-se que T. atopovirilia pode completar mais do que 32 gerações ao longo do ano. Estes resultados indicam que T. atopovirilia possui potencial de utilização para o controle de D. hyalinata com maiores chances de sucesso entre as temperaturas de 24°C e 27°C as quais também são apropriadas para o cultivo de cucurbitáceas.

The development and parasitism of Diaphania hyalinata L. eggs by Trichogramma atopovirilia Oatman & Platner and its thermal requirements were studied at the temperatures of 18, 21, 24, 27, 30 and 33°C. Thirty eggs of D. hyalinata were exposed to three females of T. atopovirilia for 5h at 25°C and incubated at the different temperatures. The developmental time from egg exposure to adult, parasitism viability, number of adults per parasitized host egg and progeny sex ratio were monitored. The developmental time from egg to adult emergence of the parasitoid exhibited inverse relationship to the temperature, lasting 24.12 days at 18°C and 7.36 days at 33°C. Parasitism viability at 24, 27 and 30°C was higher than 90%. The ratio of T. atapovirilia adult produced per egg and its sex ratio were not affected when using D. hialynata as host. The lowest threshold temperature (Tb) and estimated degree-days over Tb required by T. atopovirilia to develop on eggs of D. hyalinata was 11.99°C and 130.42ºC, respectively. Considering the temperature regimes of two areas where cucurbitaces are cultivated in Bahia State (Rio Real and Inhambupe County) it was estimated that T. atopovirilia can achieve more than 32 generation per year. The results suggest that T. atopovirilia has potential to control D. hyalinata eggs with better chance of success under temperature regimes ranging from 24 to 27°C that meets the suitable field conditions for cropping cucurbitaces.
