The best treatment modality is still under discussion. Resection of the lesion with partial ACL debridement has shown good results without the occurrence of instability. The authors present a case of mucoid degeneration of the ACL treated with resection of the mucoid degeneration and partial debridement of the ACL by arthroscopy.

Transcultural adaptation of a scale for exclusive breastfeeding to be used in Brazil.

OBJECTIVE: The aim of this study was to perform a cross-cultural adaptation of the Breastfeeding Self-Efficacy Scale in Exclusive Breastfeeding for use in a Brazilian-Portuguese context. METHODS: The cross-cultural adaptation process involved the translation from original English into Brazilian Portuguese by two qualified and independent translators. Both translations were synthesized into a single version that was back-translated into English. An expert committee was created to assess linguistic equivalences, formulating a pre-final version that was tested on ten nursing women attending a maternity hospital. To assess its psychometric properties, a cross-sectional study was carried out. The population consisted of 99 nursing women from a reference maternity hospital in southern Brazil. The scale's stability and internal consistency were measured through Cronbach's alpha. The Pearson's correlation coefficient and the intraclass correlation coefficient between two applications were assessed to ascertain the Breastfeeding Self-Efficacy Scale in Exclusive Breastfeeding-Br scale's reliability. The construct validity was evaluated through exploratory factorial analysis. RESULTS: The Breastfeeding Self-Efficacy Scale in Exclusive Breastfeeding-Br showed a general Cronbach's alpha of 0.849. The test-retest analysis showed a Pearson's correlation coefficient of 0.483 and intraclass correlation coefficient of 0.645. The exploratory factorial analysis showed two domains among the nine items of the Breastfeeding Self-Efficacy Scale in Exclusive Breastfeeding-Br: the functional domain, including six items, and the cognitive domain, including three items, explaining 59.77% of the variance. CONCLUSION: The Breastfeeding Self-Efficacy Scale in Exclusive Breastfeeding-Br was considered adequate for the cultural context and reliable and valid for Brazilian nursing women.

A high-sugar diet, but not obesity, reduces female fertility in Drosophila melanogaster.

Obesity is linked to reduced fertility in various species, from Drosophila to humans. Considering that obesity is often induced by changes in diet or eating behavior, it remains unclear whether obesity, diet, or both reduce fertility. Here, we show that Drosophila females on a high-sugar diet become rapidly obese and less fertile as a result of increased death of early germline cysts and vitellogenic egg chambers (or follicles). They also have high glycogen, glucose and trehalose levels and develop insulin resistance in their fat bodies (but not ovaries). By contrast, females with adipocyte-specific knockdown of the anti-obesity genes brummer or adipose are obese but have normal fertility. Remarkably, females on a high-sugar diet supplemented with a separate source of water have mostly normal fertility and glucose levels, despite persistent obesity, high glycogen and trehalose levels, and fat body insulin resistance. These findings demonstrate that a high-sugar diet affects specific processes in oogenesis independently of insulin resistance, that high glucose levels correlate with reduced fertility on a high-sugar diet, and that obesity alone does not impair fertility.

Parto vaginal operatório / Operative vaginal delivery

PONTOS-CHAVE Quando utilizados na técnica correta, fórcipes e vácuo-extratores apresentam baixos índices de complicações. Para o feto com sinais de hipóxia no período expulsivo, o parto vaginal operatório tem potencial para reduzir a exposição aos fatores intraparto que promovem a encefalopatia hipóxico-isquêmica. Fórcipes médios e/ou rotacionais são opções apropriadas em circunstâncias selecionadas e exigem habilidade e experiência. Os fórcipes são mais resolutivos do que os vácuo-extratores para o parto vaginal operatório, porém são mais associados a lacerações perineais graves. Céfalo-hematoma é mais provável de ocorrer com o aumento na duração da vácuo-extração. Os vácuo-extratores de campânulas flexíveis apresentam taxas maiores de falha, porém apresentam menores incidências de trauma no couro cabeludo do neonato. (AU)

Tendência temporal de nascidos prematuros no estado de Santa Catarina entre 2011 e 2021 / Temporal trend of premature birth in the state of Santa Catarina between 2011 and 2021

Objetivo: Analisar a tendência temporal de nascimentos prematuros no estado de Santa Catarina entre 2011 e 2021. Métodos: Estudo observacional ecológico de tendência temporal realizado com informações do banco de dados do Sistema de Informação sobre Nascidos Vivos do estado de Santa Catarina (2011-2021), disponibilizado pela Diretoria de Vigilância Epidemiológica. Foram analisados todos os nascidos vivos prematuros segundo o ano de processamento e o local de residência em Santa Catarina (110.422). Foram incluídos os nascidos vivos de gestação com menos de 37 semanas completas. As taxas de nascimentos prematuros foram calculadas proporcionalmente à totalidade de nascimentos e calculadas segundo macrorregião, idade materna, número de consultas do pré-natal, instrução materna e cor de pele. Para o cálculo da tendência temporal, foi utilizada a regressão linear simples, com intervalo de confiança de 95% (p ≤ 0,05). Resultados: A taxa média de nascimentos prematuros no estado de Santa Catarina foi de 10,57%, com tendência estável (p < 0,001). Maiores taxas específicas foram encontradas nas macrorregiões Meio Oeste e Serra e Planalto Norte e Nordeste (11,46%), extremos de idade (10-14 anos e 45-64 anos) e menor escolaridade. Maior número de consultas de pré-natal apresentou taxa de prematuridade menor (7,69%). Tendências crescentes das taxas foram apenas encontradas na macrorregião Grande Oeste, faixa etária materna entre 40-44 anos e entre 4-6 consultas de pré-natal. Conclusão: A tendência da taxa de prematuridade manteve-se estável em Santa Catarina. Baixo número de consultas de pré-natal, extremos de idades e baixa escolaridade mostraram taxas maiores de prematuridade. (AU)

Objective: Analyzing the temporal trend of premature births in the state of Santa Catarina between 2011 and 2021. Methods: Observational ecological temporal trend study carried out with information from the database of the Information System on Live Births in the state of Santa Catarina (2011-2021), made available by the Epidemiological Surveillance Directorate. All premature live births were analyzed according to the year of processing and place of residence in Santa Catarina (110,422). Live births of less than 37 completed weeks were included. The rates of premature births were calculated in proportion to the total number of births and calculated according to macro-region, maternal age, number of prenatal consultations, maternal education and skin color. Simple linear regression was used to calculate the temporal trend, with a confidence interval of 95% (p ≤ 0.05). Results: The average rate of premature births in the state of Santa Catarina was 10.57%, with a stable trend (p < 0.001). Higher specific rates were found in the Midwest and Serra, North Plateau and Northeast macro-regions (11.46%), age extremes (10-14 years and 45-64 years) and lower schooling. A greater number of prenatal consultations had a lower prematurity rate (7.69%). Increasing trends in rates were only found in the Grande Oeste macro-region, maternal age group between 40-44 years and between 4-6 prenatal consultations. Conclusion: The prematurity rate trend remained stable in Santa Catarina. Low number of prenatal consultations, extremes of age and low education showed higher rates of prematurity. (AU)

Soybean injury caused by the application of subdoses of 2,4-D or dicamba, in simulated drift.

2,4-D or dicamba can cause injuries and other deleterious effects on non-tolerant soybeans. Thus, the objective was to evaluate the potential for injury of subdoses of 2,4-D or dicamba, in drift simulation, for application in non-tolerant soybeans. Two experiments were carried out, one with 2,4-D and the other with dicamba. The treatments consisted of the application, in post-emergence of non-tolerant soybean, of subdoses 0; 1.35; 2.68; 5.37; 10.72; 21.45 and 42.9 g acid equivalent (ae) ha-1 2,4-D choline salt or dicamba diglycolamine (DGA) salt. Injury symptoms in plants, plant height and yield were evaluated, and the results were subjected to regression analysis. Polynomial fit was possible for the doses of both herbicides, with deleterious effects on soybean, with reductions in height and yield. The application of 2,4-D ≥ 10.72 g ae ha-1 was enough to cause injuries greater than 10% in plants, in simulated drift. The application of dicamba ≥1.35 g ae ha-1 was enough to cause injuries greater than 30% in plants, in simulated drift. For both herbicides, greater potential for injury and reductions in soybean yield were observed for the application of the highest doses (21.45 and 42.9 g ae ha-1).

O lúdico no processo de hospitalização das crianças com câncer / Plays in the hospitalization process of children with cancer

Trata-se de uma pesquisa que tem como objetivo analisar as contribuições do lúdico para o processo de hospitalização das crianças com câncer. Durante a sua hospitalização, a criança é afetada em seu estado físico, psicológico ou emocional, porém isso pode ser amenizado através de atividades lúdicas. Metodologicamente, esta pesquisa foi desenvolvida na abordagem qualitativa com método da hermenêutica dialética, que envolveu crianças em tratamento no hospital de referência na cidade de Recife/PE. Nesse caso, a comunicação foi tratada através dos dados recolhidos em fontes bibliográficas, observações dos jogos através do diário de campo e das entrevistas semiestruturadas com as crianças com câncer e seus acompanhantes. Com isso, foi constatado que a ludicidade é um recurso terapêutico enriquecedor, que contribuiu para ao desenvolvimento das crianças com câncer.

This research aims to analyze playfulness's contributions to the hospitalization process of children with cancer. During hospitalization, a child is affected physically, psychologically, or emotionally; however, this can be alleviated through playful activities. Methodologically, this research was developed in a qualitative approach based on dialectic-hermeneutics, which involved children undergoing treatment at a reference hospital in the city of Recife/PE. In this case, communication was treated through data collected from bibliographic sources, observations of the games through field diaries, and semi-structured interviews of children with cancer and their caretakers. Thus, it has been found that playfulness is an enriching.

Association between prenatal and neonatal factors and occurrence of asthma symptoms in six-year-old children.

The objective was to estimate association between prenatal and neonatal factors and asthma symptoms in children at six years of age. A cross-sectional study using secondary data from a cohort study with a sample of 578 children was carried out. Data were analyzed using three levels hierarchical Poisson Regression. Of the 578 children included in the study, 43.4% (95% CI 39.4; 47.4) had asthma symptoms. The variables with significantly higher prevalence of symptoms and asthma at six years of age were: male gender, with 5% higher prevalence (PR = 1.05 95% CI 1.01; 1.11) (p = 0.043); children of pregnant women presenting infectious diseases with 7% higher prevalence (PR = 1.07; 95% CI 1.02; 1.13) (p = 0.011); children who were not breastfed, with a 12% higher prevalence (PR = 1.12; 95% CI 1.02; 1.24) (p = 0.022) and children with respiratory problems in the first month of life, with a 14% higher prevalence (PR = 1.14; 95% CI 1.01; 1.29) (p = 0.033). It could be concluded that male gender, time-independent breastfeeding deprivation and respiratory problems in the first month of life were independently associated with asthma symptoms at six years of age. The occurrence of infectious diseases during pregnancy was the only factor with intrauterine physiology that was associated with the occurrence of asthma symptoms at six years of age.

Beyond the eye: Kynurenine pathway impairment causes midgut homeostasis dysfunction and survival and reproductive costs in blood-feeding mosquitoes.

Insect ommochrome biosynthesis pathways metabolize tryptophan to generate eye-color pigments and wild-type alleles of pathway genes are useful phenotypic markers in transgenesis studies. Pleiotropic effects of mutations in some genes exert a load on both survival and reproductive success in blood-feeding species. Here, we investigated the challenges imposed on mosquitoes by the increase of tryptophan metabolites resulting from blood meal digestion and the impact of disruptions of the ommochrome biosynthesis pathway. Female mosquitoes with spontaneous and induced mutations in the orthologs of the genes encoding kynurenine hydroxylase in Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus exhibited impaired survival and reproductive phenotypes that varied in type and severity among the species. A compromised midgut permeability barrier function was also observed in An. stephensi. Surprisingly, mutant mosquitoes displayed an increase in microbiota compared to controls that was not accompanied by a general induction of immune genes. Antibiotic treatment rescued some deleterious traits implicating a role for the kynurenine pathway (KP) in midgut homeostasis. Supplemental xanthurenic acid, a KP end-product, rescued lethality and limited microbiota proliferation in Ae. aegypti. These data implicate the KP in the regulation of the host/microbiota interface. These pleiotropic effects on mosquito physiology are important in the development of genetic strategies targeting vector mosquitoes.

Real-world data on metastatic breast cancer in Goiânia, Brazil: a 17-year analysis (1995­2011)

Introduction: Most of the data on metastatic breast cancer (MBC) originate from hospital-based studies or controlled trials involving specific populations and controlled treatments. In this respect, few population-based studies have analyzed the profile of MBC in low- and middle-income countries. Objective: To describe the epidemiological profile of women with de novo MBC using data from a population-based cancer registry (PBCR). Methods: An ecological study conducted in a PBCR in Goiânia, Brazil, for the 1995­2011 period. Women with MBC at diagnosis were included and the standardized incidence rate and annual percent change (APC) over the period were calculated. The women's clinical and demographic characteristics and data on diagnosis and treatment were analyzed. Results: Overall, 5,289 cases of breast cancer were registered in the Goiânia PBCR, 277 (5.2%) at metastatic stage. The adjusted incidence was 8.9/100,000 in 1995 and 6.04/100,000 in 2011 (APC: 1.1; p=0.6). Most of the patients (70.3%) were receiving care within the public healthcare system and the mean age at diagnosis was 54.7±14.5 years. Additional data for a subpopulation of 156 patients were identified at the city's two main treatment centers. According to immunohistochemistry, 53 women (67.1%) had hormone receptor-positive cancer. Of these, 14.0% (6/43) received endocrine therapy as first-line systemic treatment and 48.5% (17/35) as second-line treatment. A comparison of clinical data between the 1995­2003 and 2004­2011 periods revealed no significant differences in age, histological grade, locoregional staging, the presence of symptoms at diagnosis, or in treatment. Conclusion: This study population of women with MBC consisted predominantly of locally advanced tumors and the luminal-like subtype. The incidence rate of MBC in Goiânia did not change over the 17-year period. Most cases received chemotherapy as firstline systemic treatment irrespective of the tumor phenotype.
