RESUMO

Multidrug-resistant pathogens have emerged worldwide. We have driven the hypothesis that the non-use of fluoroquinolone prophylaxis during neutropenia could reduce antibiotic resistance in Gram-negative bacteria that cause bloodstream infections (BSIs) in hematopoietic stem cell transplantation (HSCT) patients and that this change in resistance pattern could lead to an impact on BSI mortality. This is a quasi-experimental study comparing BSI incidence, resistance patterns of bacteria that cause BSI, and BSI mortality when levofloxacin prophylaxis was routine for neutropenic HSCT patients (2016-2018) to when fluoroquinolone prophylaxis was discontinued in our center (2019). Bivariate comparisons and multivariate logistic regression models were used for analyses. A total of 310 HSCTs (66 (21%) allogeneic and 244 (79%) autologous) were performed during the study period. Sixty (19%) patients had BSIs, 30 in each evaluated period. The discontinuation of levofloxacin prophylaxis was associated with an increase in BSI incidence and a decrease in the resistance rates of causative BSI bacteria and in BSI 30-day mortality. The increase in the rate of resistant bacteria causing BSI and in BSI mortality might outweigh the benefits of a decrease in BSI incidence caused by fluoroquinolone prophylaxis in neutropenic HSCT patients. We suggest that the routine use of fluoroquinolone in this context be revisited.

RESUMO

On 16-17 January 2020, four suspected mumps cases were reported to the local Public Health Authorities with an epidemiological link to a local school and football club. Of 18 suspected cases identified, 14 were included in this study. Laboratory results confirmed mumps virus as the cause and further sequencing identified genotype G. Our findings highlight that even with a high MMR vaccine coverage, mumps outbreaks in children and young adults can occur. Since most of the cases had documented immunity for mumps, we hypothesise that waning immunity or discordant mumps virus strains are likely explanations for this outbreak.

RESUMO

The poultry red mite Dermanyssus gallinae (De Geer) is the most important haematophagous ectoparasite in the poultry industry. The use of synthetic acaricides for this control is presenting risks related to human food. In this sense, plant secondary metabolites are promising for controlling this pest. Thus, this study aimed to evaluate the acaricidal activity of Duguetia lanceolata A.St.-Hil. (stem bark), Xylopia emarginata Mart. (stem bark), and Xylopia sericea A.St.-Hil. (stem bark and fruits) against D. gallinae. Additionally, the secondary metabolite profile of the X. emarginata was analysed by UFLC-DAD-ESI(+)-MS/MS (micrOTOF-QII) and data analysis was performed using the Molecular Networking. In a topical application test, all plant species tested showed bioactivity, in that order of toxicity with the respective probability survival: X. emarginata (stem bark) (0.28) > X. sericea (stem barks) (0.35) > X. sericea (fruits) and D. lanceolata (stem bark) (0.47). The most promising results were found for X. emarginata (LC50 = 331.769 µg/cm2). It is noteworthy that the LC50 of the insecticide cypermethrin was 1234.4 µg/cm2, which was 73% higher than that of X. emarginata. The metabolomic profile of X. emarginata revealed the presence of alkaloids, amides, terpenoids, and phenolic compounds. This is the first report of X. emarginata acaricidal activity against D. gallinae and exploratory chemical analysis by untargeted metabolomics and the molecular network of this plant.

RESUMO

BACKGROUND: Inherited metabolic diseases (IMD) are complex medical conditions. Thanks to improvements in diagnosis and treatment, a growing number of pediatric IMD patients reach adulthood. Thus, clinical care of adults with IMD has emerged as a new and challenging reality. This purpose of this study of adults with IMD in an adult metabolic clinic at two academic hospitals (Lausanne and Geneva) was to help inform decisions on the future organization of health care for this group of patients. METHODS: All adult patients with a biochemical and/or genetic diagnosis of IMD followed at the clinics were included in the study. Electronic patient records were reviewed for clinical features, diagnostic studies, treatment and long-term outcome. Data of undiagnosed patients referred for suspected IMD were analyzed separately. RESULTS: 126 patients were included in the study. The most prevalent group of diseases was small molecules disorders with 82 (65%) patients, followed by energy defects disorders with 29 (23%) patients and complex molecules disorders with 15 (12%) patients. Overall, 64% of patients were diagnosed before, and 36% after the age 16 years. Among the 126 cases, 51% suffered from medical complications. 79% of the patients were receiving a specific treatment for their disease. Among the 138 undiagnosed patients referred for suspicion of IMD, investigations lead to a genetic diagnosis in 24 (17%) patients. 19 had confirmation of an IMD, 5 were found to have another genetic condition. CONCLUSIONS: This retrospective study reveals significant features of adult IMD cohort. The disorders are heterogeneous, and there is no one-size-fits-all approach - treatment must be tailored to fit each specific disorder in each individual patient. Even patients who are followed at the dedicated clinic are not protected from metabolic decompensations and/or chronic organ-specific complications. While it is commonly assumed that patients with IMD are more stable once they become adults, our data show that the diseases continue to exact a lifelong toll. A coordinated monitoring of target organs by a multidisciplinary team is needed. To ensure that the success in diagnosis and treatment of individuals with IMD is sustained, there is a clear requirement for adequately staffed adult IMD clinics.

RESUMO

The poultry red mite, Dermanyssus gallinae, is a cosmopolitan ectoparasite in hens and has been considered an important threat to the egg production industry. This study evaluated an alternative to manage poultry red mite populations as a complement to conventional chemical treatments and other control strategies in poultry houses. A simple autoinoculation device prepared with corrugated cardboard (CB) or loofah sponge (LS) as inert supports to anchor Beauveria bassiana conidia was used to aggregate and infect mites from infested poultry houses. In the laboratory, mites gathered inside the traps and the average mortalities by the fungus were higher than 70% in CB and LS traps after 5 and 4 days of exposure, respectively. Conidial viability was around 80% in CB and LS traps after 14 and 60 days under unrefrigerated conditions (26 °C), respectively. Both trap types tied to hen cages efficiently captured fed mites after blood meal, and fungal infection was observed in 65-90% of the mites in field tests. Between 5 and 25% of the mites recaptured in monitoring cardboard traps installed immediately after CB and LS removal were infected by B. bassiana. According to our results, the use of B. bassiana in an autoinoculation strategy is a potential alternative method for D. gallinae control.

RESUMO

BACKGROUND: Extramedullary plasmacytomas occurs in about 20% of multiple myeloma (MM) recurrences. Extramedullary disease seems to respond poorly to thalidomide and has adverse prognostic implication. When disease recurs in the oral cavity with soft tissue infiltration, some authors defend upfront surgical excision prior to radiotherapy with the aim of achieving better local control. We describe herein such an atypical case of recurrence from MM, with complete local response after 2 cycles of chemotherapy. Unfortunately, disease progressed later on, and the patient died after 9 months post-recurrence. This emphasizes the prognostic impact of extramedullary disease manifestation in MM.

RESUMO

Reduced-intensity-conditioned allogeneic stem cell transplantation (SCT) remains a potentially curative approach for patients with relapsed/refractory Hodgkin lymphoma (HL) after an autologous stem cell transplantation. In the absence of an HLA-identical donor, haploidentical SCT (haplo-SCT) with post-transplantation cyclophosphamide (PT-Cy) has been evaluated with favorable preliminary results. We evaluated 24 patients who underwent haplo-SCT for relapsed/refractory HL. The conditioning regimen consisted of cyclophosphamide, fludarabine, and total body irradiation. Graft-versus-host disease (GVHD) prophylaxis consisted of a calcineurin inhibitor, mycophenolate mofetil, and PT-Cy (50 mg/kg/day for 2 days) for all patients. After a median follow-up of 2 years, the cumulative incidence (CI) of nonrelapse mortality was 26% and the CI of grades II to IV acute GVHD and chronic GVHD were 17% and 24%, respectively. Estimation of progression-free and overall survival at 2 years were 54% and 66%%, respectively. Haplo-SCT is a valuable option for relapsed/refractory HL patients after a failed autologous SCT, with favorable survival and relatively low risk of GVHD.

RESUMO

ABSTRACT CONTEXT AND OBJECTIVE: Alcohol consumption during pregnancy is a significant social problem that may be associated with adverse perinatal outcomes. The aim of this study was to describe alcohol consumption during pregnancy and to study its association with low birth weight, newborns small for gestational age and preterm birth. DESIGN AND SETTING: Nested cohort study, in the city of Ribeirão Preto, São Paulo, Brazil. METHODS: 1,370 women and their newborns were evaluated. A standardized questionnaire on health and lifestyle habits was applied to the mothers. Anthropometry was performed on the newborns. Alcohol consumption was defined as low, moderate or high, as defined by the World Health Organization. Adjusted logistic regression analysis was used. RESULTS: 23% of the women consumed alcohol during pregnancy. Consumption mainly occurred in the first trimester (14.8%) and decreased as the pregnancy progressed. The median alcohol intake was 3.89 g (interquartile range, IQR = 8 g) per day. In the unadjusted analysis, alcohol consumption increased the risk of low birth weight almost twofold (odds ratio, OR 1.91; 95% confidence interval, CI: 1.25-2.92). The risk was lower in the adjusted analysis (OR 1.62; 95% CI: 1.03-2.54). Alcohol consumption did not show associations with small for gestational age or preterm birth. There was greater risk of low birth weight and newborns small for gestational age and preterm birth among mothers who were both smokers and drinkers. CONCLUSIONS: The alcohol consumption rate during pregnancy was 23% and was independently associated with low birth weight, but there was no risk of newborns small for gestational age or preterm birth.


RESUMO CONTEXTO E OBJETIVO: O consumo de álcool durante a gravidez é um problema social significativo que pode estar associado a resultados perinatais adversos. O objetivo deste estudo foi descrever o consumo de álcool na gestação e avaliar sua associação com recém-nascido de baixo peso, pequeno para idade gestacional e pré-termo. TIPO DE ESTUDO E LOCAL: Estudo de coorte aninhado, na cidade de Ribeirão Preto, São Paulo, Brasil. Foram avaliadas 1.370 mulheres e seus recém-nascidos. Foi aplicado às mães um questionário padronizado sobre saúde e hábitos de vida. Antropometria foi realizada nos recém-nascidos. MÉTODOS:Consumo de álcool foi definido como baixo, moderado e elevado segundo a Organização Mundial de Saúde. Foi utilizada análise de regressão logística ajustada. RESULTADOS: 23% das gestantes consumiram álcool durante a gravidez. A maior parte do consumo ocorreu no primeiro trimestre (14,8%) e diminuiu conforme progredia a gravidez. A mediana de ingestão de álcool foi de 3,89 g (interval interquartil, IIQ = 8 g) por dia. Na análise não ajustada, o consumo de álcool aumentou em quase duas vezes (odds ratio , OR 1,91, intervalo de confiança, IC 95%; 1,25-2,92) o risco de baixo peso, que se reduziu após ajuste (OR 1,62; IC 95%; 1,03-2,54). Não houve associação entre consumo de álcool e pequeno para idade gestacional ou pré-termo. Observou-se maior risco de baixo peso, neonato pequeno para idade gestacional e pré-termo em gestantes simultaneamente fumadoras e bebedoras. CONCLUSÕES: O consumo de álcool na gestação foi de 23% e esteve associado independentemente com o baixo peso ao nascer, mas não houve risco para neonato pequeno para idade gestacional e pré-termo.

RESUMO

Frailty can be defined as a biologic syndrome that results from decline in multiple systems leading to vulnerability, with poorer capacity of the organism to maintain homeostasis facing stressing events. Physical symptoms of frailty involve unintentional weight loss, decreased physical activity level, exhaustion, muscle weakness, impaired balance and gait. Together, these symptoms can compromise independence in activities of daily living. Physical Therapy can improve muscle strength, balance, gait and cardiorespiratory aptitude of frail elderly, but remains unclear what is the best intervention strategy: unimodal or multimodal interventions, with combined exercises. This systematic review aimed: (1) to compare the efficacy of unimodal and multimodal Physical Therapy interventions; (2) to analyze its effects on clinical outcomes and (3) to elucidate what is the best modality of exercise and its combination in order to improve physical symptoms and independence in frail elderly. Searches were conducted in PubMed, Medline, PEDro, Lilacs and Scielo databases. We obtained 2,579 studies and 17 were included in analysis. Studies analyzed the following clinical outcomes: mobility, muscle strength, balance, falls and fear of falling, quality of life and functional capacity. We conclude that both unimodal and multimodal interventions have potential to promote beneficial effects, but the analyzed studies have important methodological issues that negatively affect their quality. Although the beneficial effects of both interventions, the quality of studies analyzed does not allow us to generalize these effects. We suggest that new clinical trials should be conducted with a stronger methodology and according to current guidelines for randomized clinical trials.


A fragilidade pode ser definida como uma síndrome biológica que resulta da diminuição da função de diversos sistemas, conduzindo à vulnerabilidade e pior capacidade do organismo para manter a homeostase frente a eventos estressores. As características físicas da fragilidade envolvem perda involuntária de peso, diminuição do nível de atividade física, cansaço, fraqueza muscular, diminuição do equilíbrio e marcha. Esses sintomas podem comprometer a independência nas atividades de vida diária. A fisioterapia pode melhorar a força muscular, equilíbrio, marcha e aptidão cardiorrespiratória de idosos frágeis, mas não está claro qual é a melhor estratégia: intervenções unimodais ou multimodais, com exercícios combinados. Sendo assim, esta revisão sistemática objetivou: (1) comparar a eficácia de intervenções unimodais e multimodais; (2) analisar os efeitos sobre os resultados clínicos e (3) elucidar qual a melhor modalidade de exercício e suas combinações na melhora dos sintomas físicos e independência em idosos frágeis. Foram realizadas buscas nas bases de dados PubMed, Medline, Pedro, Lilacs e Scielo. Obtivemos 2.579 estudos e 17 foram incluídos na análise. Os estudos incluídos analisaram os desfechos mobilidade, força muscular, equilíbrio, quedas e medo de cair, qualidade de vida e capacidade funcional. Concluimos que as intervenções unimodais e multimodais têm potencial para promover efeitos benéficos, mas os estudos analisados apresentaram falhas metodológicas que afetam a qualidade dos mesmos. Apesar dos benefícios de ambas as intervenções, a qualidade dos estudos não nos permite generalizar esses efeitos. Sugerimos que novos ensaios clínicos devam ser conduzidos, com metodologia de acordo com as recomendações para ensaios clínicos randomizados.
