Abstract Plasticulture improves crop quality and yield through polymeric films, but their improper disposal harms the environment due to humidity and contamination. This study aimed to develop biodegradable mulch films using soybean and peanut hulls and poly (butylene-adipate-co-terephthalate) (PBAT). The residues were characterized by thermogravimetric analysis and mulch films were evaluated by water absorption, contact angle and mechanical properties. The thermal behavior of the residues indicated stability below 200ºC. The agro-waste improved hydrophobicity but increased the water absorption values of the films by up to 18.5x (PBAT/SH5 after 14 days). Micrographs obtained by scanning electron microscopy indicated an important distribution of residue particles and formation of agglomerates, leading to lower mechanical performance. The study found that agro-industrial residues in powder form can be added to the polymeric matrix to produce biodegradable mulch films through traditional processing techniques. This approach has the potential to contribute to a more sustainable production system.

Abstract Background: Medical residents in operating rooms present signs and symptoms associated with occupational exposure to surgical smoke. Objective: To determine the incidence and relative risk of developing signs and symptoms associated with surgical smoke exposure in medical residents. Methodology: A cohort study was conducted with medical residents exposed and unexposed to surgical smoke. Data collection was conducted in two moments, over four months, using a questionnaire containing items on sociodemographic and occupational characteristics and surgical smoke-related signs and symptoms and protective measures. Results: The most frequent signs and symptoms in those exposed compared to those unexposed to surgical smoke were foreign body sensation in the throat, burning sensation in the pharynx, irritation of other mucous membranes, and nasopharyngeal lesions. The use of protective eyewear was a protective factor for those exposed (p = 0.01). Conclusion: Surgical smoke-related signs and symptoms are higher in medical residents exposed than in those unexposed. The relative risk of developing signs and symptoms is always higher for those exposed.

Abstract Objective: The objective of this study was to analyze masticatory characteristics in children from 7 to 10 years, and to compare these characteristics among normal weight, overweight and obese children. Methods: This is a cross-sectional study, conducted in northeast Brazil, with a sample of 160 children, aged 7 to 10 years. The authors evaluated: nutritional and dental status; food intake; masticatory parameters and orofacial myofunctional characteristics. The children were divided according to nutritional status into normal weight (n = 101), overweight (n = 33) and obesity (n = 26) groups. Results: The results showed that Obese children had a larger bite size (g) (median = 6.0, Q1-Q3 = 4.0-9.0, p = 0.049) and performed fewer masticatory sequences (median = 3.0, Q1-Q3 = 2.0-3.2, p = 0.024) than children with normal weight (median = 5.0, Q1-Q3 = 4.0-7.0; median = 4.0, Q1-Q3 = 3.0-5.0). Furthermore, obese children finished feeding in a shorter time (s) (median = 62.5, Q1-Q3 = 50.5-70.0, p = 0.039) than normal weight children (median = 66.0, Q1-Q3 = 56.5-78.0) and overweight children (median = 66.0, Q1-Q3 = 58.0-81.5). Conclusions: The present results suggest that obese children present changes in mastication, evidenced by larger bite-size, performing fewer masticatory sequences and rapid mastication, which may contribute to increased food consumption and the development of excess weight.

ABSTRACT Objective: Intrauterine environment can induce fetal metabolic programming that predisposes to adiposity-related chronic diseases in its lifespan. We examined the associations of parental nutritional status and gestational weight gain with offspring body composition in early adulthood. Materials and methods: This is cross-sectional analysis of female participants of the NutriHS who were submitted to questionnaires, clinical examinations and body composition assessed by DXA. Association of pre-conception parental BMI and maternal gestational weight gain (exposures) with body composition measurements (outcomes) were analyzed using multiple linear models adjusted for Directed Acyclic Graphs-based covariables (maternal and paternal educational level, maternal age, and tobacco, alcohol and/or drugs use). The sample included 124 women (median 28 (24-31) years) with a mean BMI of 25.4 ± 4.7 kg/m2. Results: No association between previous paternal BMI and offspring’s body composition was detected. In the fully adjusted linear regression model, maternal BMI was associated with offspring’s total lean mass (β = 0.66, p = 0.001), appendicular skeletal muscle mass index (ASMI) (β = 0.11, p = 0.003) and fat mass index (FMI) (β = 0.03, p = 0.039). Gestational weight gain was associated with increased offspring’s BMI (OR 1.12 [95% CI 1.02-1.20], p = 0.01). The linear regression model adjusted for maternal age and maternal and paternal education levels showed associations of gestational weight gain with offspring’s ASMI (β = 0.42, p = 0.046), FMI (β = 0.22, p = 0.005) and android-to-gynoid fat ratio (β = 0.09, p = 0.035). Conclusion: Our findings suggest that preconception maternal BMI could influence lean mass and general adiposity of young adult female offspring and that gestational weight gain could be useful for predicting centrally distributed adiposity.

Abstract Objective: The aim of our study was to evaluate the expression of MMP-2 and MMP-9 as a prognostic factor in patients diagnosed with Hodgkin Lymphoma (HL). Methods: In the present study, 45 paraffin biopsies from patients up to 19 years old diagnosed with HL were used in two referral hospitals in the state of Pernambuco, Brazil. Risk groups were classified into favorable and unfavorable, according to Ann Arbor. The expression of matrix metalloproteinases 2 and 9 and their inhibitors was performed by immunohistochemistry (IHC). Data were analyzed using the GraphPad Prism 5 program. Results: MMP-2 intensity pattern was stronger (> 10% of the total field) in patients with stage III/ IV and B symptoms. MMP-2 showed an association with the risk group (p = 0.0388). That is, the stronger the MMP-2 marking, the greater the unfavorable risk. However, for MMP-9 there was no difference in the stronger intensity pattern in relation to stages I/II and III/IV, only in the presence of B symptoms. MMP-9 showed an association with B Symptoms (p = 0.0411). Therefore, patients with B symptoms have higher MMP-9 expression. Conclusion: Our results suggest that MMP-2 expression is associated with HL progression. While MMP-9 expression is related to the clinical worsening of these patients. However, further studies are needed to evaluate the exact role of these proteins in hematologic malignancies.

ABSTRACT. The objective was to evaluate fertility, cyclicality behavior, and sexual performance of Pantaneiro sheep throughout the year’s photoperiods in Mato Grosso do Sul - Brazil. Two experiments were conducted. In experiment one, the ewes used aged between 2 and 4 years, distributed in three homogeneous groups of 54 animals and subjected to reproductive evaluation in three different predefined luminosity periods, consisting of autumn (11h 45 min.), spring (12h 30 min.), and summer (12h 55 min.). The characteristics studied were body weight (BW), body condition score (BCC), estrus distribution (EST), percentage of pregnant females per cycle (%P), plasma progesterone (PP), and fertility (F) in the three predefined seasons. The mating system used was controlled natural nocturnal and lasted for 45 days. Experiment two, evaluated the ram sexual activity. The males (10) were individually exposed to four ovariectomized ewes. The ewes cycled during evaluated seasons, and the highest fertility was observed in animals with BCC >2.75. The PP concentration differed among periods, and higher conception rates (F) were observed in autumn and spring. The rams (75%) had a medium of sexual performance when they performed more than two ejaculations in 20 min throughout the seasons. Pantaneiro sheep of both genders had a similar fertility index, with early and constant activity throughout the year, displaying no photoperiodism or seasonality.

ABSTRACT: The Ilex paraguariensis is a species native to Brazil, Paraguay and Argentine, valued by its positive effects on human health. Mate processing consists of the following stages: pre-drying (rapid drying at high temperature, known as sapeco operation), drying, and milling. In order to verify the current process and to propose future improvements to the mate processing, thermal and mass balance analysis were applied to industrial mate processing units. Results showed that the consumption of energy in sapeco and drying operations exceeds the calorific input necessary for these operations. These results verify the need for a change in the management of temperatures in the sapeco and drying stages of mate processing in order to optimize the consumption of energy, resulting in lower costs, with positive effects on the quality of the mate products.

RESUMO: A Ilex paraguariensis é uma espécie nativa do Brasil, Paraguai e Argentina, valorizada por seus efeitos positivos na saúde humana. O processamento do mate consiste nas seguintes etapas: pré-secagem (secagem rápida em alta temperatura, conhecida como operação de sapeco), secagem e moagem. A fim de verificar o atual processo e propor melhorias futuras no processamento de mate, foram aplicadas análises térmicas e de balanço de massa em unidades industriais de processamento de mate. Os resultados mostraram que o consumo de energia nas operações de sapeco e secagem supera o aporte calorífico necessário para essas operações. Esses resultados comprovam a necessidade de uma mudança no gerenciamento das temperaturas nas etapas de sapeco e secagem do processamento da erva-mate, a fim de otimizar o consumo de energia, resultando em menores custos, com efeitos positivos na qualidade dos produtos da erva-mate.

ABSTRACT: In the last decades, the high incidence of viruses transmitted by whiteflies has become a problem in the tomato fields, threatening, more recently, the potato crops. The present study carried out a survey of begomoviruses and criniviruses in tomato and potato crops, from 2015 to 2018, in the municipalities of Araucária, Campo do Tenente, Campo Largo, Contenda, Lapa, Faxinal, Morretes, Reserva, Castro, Palmeira and São Mateus do Sul, in Paraná State, Brazil. Total DNA and RNA from leaves were extracted and used as templates to detect, respectively, begomoviruses by PCR and criniviruses by RT-PCR. Out of 215 tomato samples, 14 from Faxinal were infected by crinivirus. The other tomato samples and 243 potato samples showed negative results for begomovirus and crinivirus. Results indicated a low incidence (6.5%) of crinivirus infecting tomato crops in Paraná State, and the nucleotide sequence of one amplified fragment shared 99.71% identity with tomato chlorotic virus (ToCV).

RESUMO: Nas últimas décadas, a alta incidência de vírus transmitidos por mosca-branca tornou-se um problema nos campos de tomateiros, ameaçando, mais recentemente, a cultura da batateira. O presente trabalho teve como objetivo realizar um levantamento de begomovírus e crinivírus em lavouras de tomateiro e batateira nos municípios de Araucária, Campo do Tenente, Campo Largo, Contenda, Lapa, Faxinal, Morretes, Reserva, Castro, Palmeira e São Mateus do Sul, no Estado do Paraná, Brasil, de 2015 à 2018. DNA e RNA totais de folhas foram extraídos e utilizados como molde para detectar begomovírus por PCR e crinivírus por RT-PCR. Das 215 amostras de tomateiros coletadas, 14 provenientes de Faxinal estavam infectadas por crinivírus. As demais amostras de tomateiro e as 243 amostras de batateira analisadas apresentaram resultados negativo para begomovírus e crinivírus. Os resultados indicaram baixa incidência (6,5%) de crinivírus infectando lavouras de tomateiros no Estado do Paraná e a sequência de nucleotídeos de um amplicon apresentou 99,71% de identidade com o crinivírus tomato chlorotic virus (ToCV).

Abstract This study aimed to translate and to perform the cultural adaptation of the instrument Illness Perception Questionnaire-Revised for Dental (IPQ-RD) into Brazilian Portuguese. The IPQ-RD consists of 34 items that assess the cognitive and emotional representation/perception of parents/caregivers of children with dental caries, with response options on a 5-point Likert scale, ranging from “Strongly agree” (score 1) to “Strongly disagree” (score 5). The higher the score, the lower the perception of the disease. The protocol consists of translation into Brazilian Portuguese, back-translation into English, revision by an Expert Review Committee, and pre-test (application in parents/caregivers of children in dental care). For some questions, the translated versions were identical (T1 = T2); for others, one version was preferred (T1 or T2); for still others, it was decided to modify terms to obtain greater clarity on the item (T3). In the first pre-test, three questions were misunderstood by more than 15% of the sample, after which the items were reviewed by the Expert Review Committee. In the second pre-test, the adapted version was applied to a new sample of parents/caregivers (n = 15) and the questions were understood by more than 85% of the participants. The Brazilian Portuguese version of the IPQ-RD was well understood by the evaluated population.

Abstract In this study, green high-density polyethylene (GHDPE) composites with 5, 10 and 15% natural powdered cork (CP) with and without 5% maleic anhydride (PE-g-MA) were developed in order to evaluate the potential of these materials for civil construction applications. The composites were produced in a co-rotating twin-screw extruder and injection molded. An impedance tube was used to determine the acoustic behavior of the composites, which were then used as ceiling tiles in prototypes of provisional constructions in order to study ascertain their performance with respect to thermal comfort in the City of Teresina, PI - Brazil. Our data indicates that composites sound absorption coefficient values are good between 500 and 1200 Hz, especially for those with a higher percentage of cork, with the lowest absorption rate observed for composites containing PE-g-MA. The composites used in the prototypes provided a decrease in the internal temperature of the built structure.

Abstract Neuromyelitis optica spectrum disorder (NMOSD) is a rare and severe inflammatory disorder of the central nervous system (CNS). It is strongly associated with anti-aquaporin 4 antibodies (AQP4-IgG), and it mainly affects young women from non-white ethnicities. However, ~ 5 to 10% of all cases have onset during childhood. Children and adolescents share the same clinical, radiologic, and laboratory presentation as adults. Thus, the same NMOSD diagnostic criteria are also applied to pediatric-onset patients, but data on NMOSD in this population is still scarce. In seronegative pediatric patients, there is a high frequency of the antibody against myelin oligodendrocyte glycoprotein (MOG-IgG) indicating another disease group, but the clinical distinction between these two diseases may be challenging. Three drugs (eculizumab, satralizumab, and inebilizumab) have been recently approved for the treatment of adult patients with AQP4-IgG-positive NMOSD. Only satralizumab has recruited adolescents in one of the two pivotal clinical trials. Additional clinical trials in pediatric NMOSD are urgently required to evaluate the safety and efficacy of these drugs in this population.

Resumo O espectro da neuromielite óptica (ENMO) é uma rara e grave doença inflamatória do sistema nervoso central (SNC), fortemente associada ao anticorpo anti-aquaporina 4 (AQP4-IgG) e que afeta preferencialmente mulheres jovens de etnias não-caucasianas. No entanto, aproximadamente de 5 a 10% de todos os casos se iniciam na infância. Crianças e adolescentes compartilham as mesmas características clínicas, radiológicas e laboratoriais dos adultos. Além disso, o mesmo critério diagnóstico de ENMO é aplicado para pacientes com início na infância. No entanto, dados da população pediátrica são escassos. Em pacientes pediátricos soronegativos, existe uma alta frequência de positividade ao anticorpo contra a glicoproteína na mielina do oligodendrócito (MOG-IgG), indicando outra patologia; porém, a distinção clínica entre as duas doenças é desafiadora. Três medicações (eculizumabe, inebilizumabe e satralizumabe) foram recentemente aprovadas para pacientes adultos com AQP4-IgG. Apenas um dos ensaios pivotais do satralizumabe recrutou adolescentes. Novos ensaios clínicos em pacientes pediátricos com ENMO são necessários para avaliar a segurança e eficácia destas drogas nesta população.

Abstract Objective To analyze fall risk and its relationship with the frailty syndrome and sociodemographic variables in older adults. Methods This is a cross-sectional, analytical and multicenter study, carried out in two university hospitals, from August 2019 to January 2020, with 323 older adults, using the Brazil Old Age Schedule (BOAS), for sociodemographic characterization, the Morse Fall Scale (MFS), to define fall risk, and the Edmonton Frail Scale (EFS), to identify the frailty syndrome. Data were analyzed using descriptive and inferential statistics. Results There was an association between fall risk and older adults aged over 70 years, with more than four preexisting diseases, without work activity, with cognitive impairment, poor general health status, with functional dependence in five to eight activities, using five or more medications, with weight loss, low functional performance, sad or depressed mood and with the installed frailty syndrome. Older adults who live alone, aged over 70 years, who have four or more previous illnesses, with functional dependence, depressed mood, who perform the Timed Up and Go (TUG) test in a time longer than 20 seconds, who use five or more medications per day and who forget to use these medications are more likely to fall at risk. Conclusion Factors related to the decline of physical, psychological and mental functions in older adults, which are exacerbated in the frailty syndrome, increase fall risk in this population.

Conclusão Fatores relacionados ao declínio de funções físicas, psicológicas e mentais nos idosos, e que se encontram exacerbados na síndrome da fragilidade, aumentam o risco para a ocorrência de quedas nessa população.

ABSTRACT Objectives: to identify whether implementing a supplementary Primary Health Care (PHC) system makes it possible to reduce care costs for older adults with heart diseases. Methods: a retrospective cohort of 223 patients with heart disease aged ≥ 60 years. Data were obtained from medical records and cost databases, assessed for a period of one year before and after PHC implementation. The results were expressed as mean absolute frequencies for number of hospitalizations and as average annual expenses expressed in dollars (US$) in relation to cost data. Results: there was a reduction in hospitalization expenses after implementing supplementary PHC (p=0.01) and a decrease in the frequency of hospitalizations for the entire sample (p=0.006). There was a reduction in the frequency of consultations at the Emergency Room among frail older adults (p=0.011). Conclusions: there was a reduction in hospitalization costs and frequency of visits to the Emergency Room after supplementary PHC.
