Objective: To systematically review the literature focusing on obstetric and perinatal outcomes in women with previous or current eating disorders (EDs) and on the consequences of maternal EDs for the offspring. Methods: The study was performed following the systematic review and meta-analysis (PRISMA) statement. PubMed, SciELO, and Cochrane databases were searched for non-interventional studies published in English or Portuguese from January 1980 to December 2020. Risk of bias was assessed using the Methods guide for effectiveness and comparative effectiveness reviews (American Agency for Healthcare Research and Quality). Results: The search yielded 441 records, and 30 articles were included. The psychiatric outcome associated with EDs in women was mainly perinatal depression. The most prevalent obstetric outcomes observed in women with EDs were vomiting, hyperemesis, bleeding, and anemia. Most studies found maternal anorexia nervosa and bulimia nervosa to be associated with low birth weight and slow fetal growth. Women with binge EDs delivered children with increased birth weight. Of the 30 studies included, methodological quality was good in seven, fair in eight, and poor in 15 studies. Conclusion: A considerable body of evidence was reviewed to assess obstetric and perinatal outcomes in EDs. Acute and lifetime EDs, especially if severe, correlated with poor perinatal, obstetric, and neonatal outcomes. Obstetricians and general practitioners should be vigilant and screen for EDs during pregnancy.

Objective: This study translated, culturally adapted, and validated a Brazilian Portuguese version (SCOFF-BR) of the Sick, Control, One Stone, Fat, Food Questionnaire (SCOFF) to screen eating disorders in young adults. Methods: This study used back-translation to culturally adapt the questionnaire according to International Society of Pharmacoeconomics and Outcome Research principles. The SCOFF-BR validation process involved a sample of men and women aged 18-32 years from a university community. After the participants completed the SCOFF-BR questionnaire, pre-trained researchers interviewed them with the Mini International Neuropsychiatric Interview (MINI). The presence of eating disorders was determined according to DSM-5 criteria. Results: Of the 361 subjects, 9.7% had an eating disorder (2.2% anorexia nervosa, 5% bulimia nervosa, and 2.5% binge-eating disorder). Using a cutoff point of two positive responses, we obtained a sensitivity of 80% and a specificity of 71.5%, with an accuracy of 72.3%. The positive and negative predictive values were 23.1% and 97.1%, respectively. Conclusion: This study demonstrated that the Brazilian version of the SCOFF questionnaire presents satisfactory accuracy and reliability to screen eating disorders among young adults in the Brazilian university community.

O presente trabalho teve por objetivo avaliar o efeito de seis temperaturas (20, 25, 28, 30, 32 e 35ºC) sobre os parâmetros biológicos de Acarophenax lacunatus (Cross & Krantz) utilizando ovos de Tribolium castaneum (Herbst) e Cryptolestes ferrugineus (Stephens) como hospedeiros. A temperatura influenciou o desenvolvimento do ácaro A. lacunatus. Os maiores valores para a progênie (19 ácaros em T. castaneum e 15 ácaros em C. ferrugineus) foram obtidos a 30ºC. O mesmo foi observado para a taxa líquida de reprodução (Ro), que revelou que a população de A. lacunatus aumentou 18 vezes em T. castaneum e 14 vezes em C. ferrugineus em uma geração. A taxa intrínseca de crescimento (r m) aumentou com a elevação da temperatura, atingindo o valor máximo a 35ºC em T. castaneum (1,608) e em C. ferrugineus (1,289). O tempo de geração foi inversamente proporcional à temperatura, variando de 1,60 a 4,85 dias em T. castaneum e de 1,96 a 5,34 dias em C. ferrugineus. Esses resultados sugerem que o ácaro A. lacunatus pode ser utilizado em programas de controle biológico de T. castaneum e de C. ferrugineus em regiões tropicais.

The aim of the present study was to assess the effect of six different temperatures on the development of Acarophenax lacunatus (Cross & Krantz) using eggs of Tribolium castaneum (Herbst) and Cryptolestes ferrugineus (Stephens) as hosts. The temperature affected the development of A. lacunatus. The largest values for the progeny (19 mites in T. castaneum and 15 mites in C. ferrugineus) were obtained at about 30ºC, as also observed for the net reproductive rate (Ro), which revealed that the A. lacunatus population increased 18 times in T. castaneum and 14 times in C. ferrugineus in a generation. The intrinsic rate of increase (r m) gradually increased with temperature, reaching the maximum value at 35ºC in T. castaneum (1,608) and C. ferrugineus (1,289). The generation time was negatively correlated with temperature, ranging from 1,60 to 4,85 days in T. castaneum and from 1,96 to 5,34 days in C. ferrugineus. These results suggest that the mite A. lacunatus may be used in programs of biological control of T. castaneum and C. ferrugineus in the tropics.

O presente trabalho teve como objetivo avaliar o efeito da interação de diferentes temperaturas com o parasita Acarophenax lacunatus (Cross & Krantz) na supressão populacional de Rhyzopertha dominica (Fabricius). Os ensaios foram realizados com e sem o parasita, em cinco repetições, às temperaturas de 20, 25, 30 e 35ºC, umidade relativa de 60 ± 5% e escotofase de 24h. As unidades experimentais consistiram de placas de Petri, contendo 40 g de grãos de trigo (13% b.u.), infestados com 10 adultos de R. dominica. Foram realizadas três inoculações de cinco fêmeas de A. lacunatus por placa de Petri. As avaliações foram realizadas depois de 20, 40, 60, 80, 100 e 120 dias do início do experimento. A interação da temperatura com A. lacunatus mostrou ser uma importante ferramenta para a supressão populacional de R. dominica. Todavia, em temperaturas maiores que 25ºC, mesmo A. lacunatus reduzindo grande proporção das fases imaturas de R. dominica, as perdas de massa dos grãos foram elevadas aos 120 dias do armazenamento. A manutenção da temperatura dos grãos armazenados a 20ºC pode ser usada como complemento para o controle biológico de R. dominica com A. lacunatus.

The objective of this study was to evaluate the effect of different temperatures with the association of the mite Acarophenax lacunatus (Cross & Krantz) on the population suppression of Rhyzopertha dominica (Fabricius). The experimental units were petri dishes containing 40 g of whole wheat grains (13% moisture content) infested with 10 adults of R. dominica, under the temperatures of 20, 25, 30 and 35ºC, with or without A. lacunatus, in five replicates. Relative humidity of 60 ± 5% and escotophase of 24h were used for all temperatures. Five days after the infestation, five mites were inoculated in each experimental unit. The evaluations were carried out at 20, 40, 60, 80, 100 and 120 days after R. dominica infestation. The interaction of the temperature with the parasite A. lacunatus was an important tool for the population suppression of R. dominica. In temperatures higher than 25ºC, however, despite the reduction of the immature stages of R. dominica, there was a high grain weight loss after 120 days. The maintenance of the temperature of the wheat grains stored at 20ºC can be used to complement the biological control of R. dominica with A. lacunatus.

O ácaro parasita Acarophenax lacunatus (Cross & Krantz) pode ser um importante agente de controle biológico de insetos-praga de grãos armazenados, mas sua presença em criações massais desses organismos é prejudicial. O objetivo deste trabalho foi avaliar a susceptibilidade desse parasita ao enxofre. As unidades experimentais consistiram de placas de Petri, contendo 30 g de grãos de trigo infestados com 30 adultos de Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae). Os tratamentos consistiram no polvilhamento dos grãos de trigo com enxofre, nas doses correspondentes a 0; 0,15; 0,30; 0,60; 0,90 e 1,20 mg i.a./g, em cinco repetições. Foram realizadas três inoculações de A. lacunatus por placa de Petri, cinco, dez e quinze dias depois da infestação de R. dominica. Em seguida, as placas foram armazenadas por 60 dias a 30 ± 1°C, 60 ± 5% UR e escotofase de 24h. O ácaro parasita mostrou-se susceptível a todas doses de enxofre avaliadas. O número de ovos de R. dominica parasitados por A. lacunatus apresentou uma tendência decrescentecom o aumento das doses do acaricida, assim como o número de fêmeas fisogástricas do ácaro. A taxa instantânea de crescimento de A. lacunatus se reduziu com o aumento das doses de enxofre, não ocorrendo o desenvolvimento do parasita nas doses superiores a 0,30 mg i.a./g. A suscetibilidade de A. lacunatus ao enxofre é importante, uma vez que não existe na literatura uma alternativa de controle desse parasita sobre criações de insetos. Além disso, esse método de controle apresenta baixo custo e é de fácil utilização.

The parasitic mite Acarophenax lacunatus (Cross & Krantz) is a potentially important biocontrol agent of stored grain insect pests, but its presence in insect mass rearing is undesirable. This study was carried out to evaluate the susceptibility of A. lacunatus to sulfur. The experimental units were petri dishes containing 30 g of whole wheat grains infested with 30 adults of Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae). The treatments consisted of pulverizing the wheat grains with sulfur, at 0, 0.15, 0.3, 0.6, 0.9 and 1.2 mg a.i./g, in five replicates. Three inoculations of A. lacunatus were carried out in each petri dish at five, ten and fifteen days after infestation with R. dominica. The petri dishes were stored for 60 days at 30 ± 1ºC, 60 ± 5% R.H. and 24h scotophase. The parasitic mite was susceptible to all sulfur doses used in the test. The number of eggs of R. dominica parasitized by A. lacunatus showed a decreasing trend with the increase in doses of sulfur, as did the number of physogastric females of the mite. The mite showed a negative correlation of their instantaneous rate of increase with sulfur dose. No mites developed at sulfur doses higher than 0.3 mg a.i./g. The susceptibility of A. lacunatus to sulfur is an important aspect to consider in the control of this parasitic mite in colonies of R. dominica. In addition, this control method has low cost and is easy to use.

A interação entre Acarophenax lacunatus (Cross & Krantz) e Anisopteromalus calandrae (Howard) pode ser uma ferramenta promissora para o manejo integrado de pragas. O objetivo deste estudo foi avaliar a compatibilidade desses dois inimigos naturais sobre Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae). As unidades experimentais consistiram de placas de Petri (140 x 10 mm), contendo 30 g de grãos de trigo com teor de água de 13% b.u. Esses grãos foram infestados com 20 adultos de R. dominica, com idade entre três e sete dias. Os tratamentos consistiram na inoculação com A. lacunatus e A. calandrae, isoladamente e em conjunto, em oito repetições. Foram realizadas três inoculações com cinco fêmeas adultas dos inimigos naturais por placa de Petri, cinco, dez e quinze dias após a infestação de R. dominica. Todos os tratamentos foram armazenados por 60 dias em câmara climática ajustada a 30 ± 1°C, 60 ± 5% UR e escotofase de 24h. Os menores números de fêmeas fisogástricas de A. lacunatus e de adultos de A. calandrae foram observados quando esses inimigos naturais estavam associados. O uso de A. calandrae sozinho ocasionou menor taxa instantânea de crescimento populacional de R. dominica e maior proteção aos grãos de trigo. Quando esse inimigo natural foi associado a A. lacunatus, além de preservar seu potencial, também apresentou os menores números de imaturos de R. dominica, demonstrando a importância dessa interação como ferramenta do manejo integrado de R. dominica em unidades armazenadoras.

The interaction between Acarophenax lacunatus (Cross & Krantz) and Anisopteromalus calandrae (Howard) may be a promising tool for the integrated pest management of stored grain insect pests. The objective of this study was to evaluate the compatibility of these two natural enemies on Rhyzopertha dominica (Fabricius). The experimental units were petri dishes (140 x 10 mm) containing 30 g of whole wheat grains (13% water content) infested with 20 adults of R. dominica. The treatments consisted of inoculation of A. lacunatus and A. calandrae, separately and associated, in eight replicates. Three inoculations of five adult females of the natural enemies were carried out in each petri dish at five, ten and fifteen days after the infestation of R. dominica. All treatments were stored during 60 days in environmental chamber at 30 ± 1°C, 60 ± 5% relative humidity and 24h scotophase. The smallest numbers of physogastric females of A. lacunatus and of adults of A. calandrae were obtained when the natural enemies were in association. The use of A. calandrae alone demonstrated a low instantaneous rate of increase (r i) of R. dominica and a high protection of the wheat grains. The association of A. calandrae with A. lacunatus led to the lowest number of immatures of R. dominica. These results demonstrate the importance of this interaction as a tool of for the integrated management of R. dominica in stored wheat grains.
