RESUMO
This work aimed to study for the first time the effects of phenolic compounds from sugarcane syrup on Saccharomyces cerevisiae ß-farnesene fermentation by removing them from this feedstock. Syrup purification was optimized through a central composite design using five types of activated charcoal: three contact times (1-24 h) and three adsorbent concentrations (10-150 g L-1 ). The optimal purification condition-charcoal pellets at 115 g L-1 and contact time of 12.5 h-led to 96.7% of phenolic compounds removal and 43.7% of syrup recovery. The effects of reducing phenolic content from approximately 7.0-0.3 mg L-1 in sugarcane syrup on yeast fermentation varied with the scale. An increase in biomolecule productivity was only observed in shake-flasks (11%) and in biomass productivity only in the 2 L bioreactor (12%). Thus, phenolic compounds from sugarcane syrup do not influence ß-farnesene production at a large scale under the conditions tested.

Executive functions are high-level cognitive processes involving abilities such as working memory/updating, set-shifting and inhibition. These complex cognitive functions are enabled by interactions among widely distributed cognitive networks, supported by white matter tracts. Executive impairment is frequent in neurological conditions affecting white matter; however, whether specific tracts are crucial for normal executive functions is unclear. We review causal and correlation evidence from studies that used direct electrical stimulation during awake surgery for gliomas, voxel-based and tract-based lesion-symptom mapping, and diffusion tensor imaging to explore associations between the integrity of white matter tracts and executive functions in healthy and impaired adults. The corpus callosum was consistently associated with all executive processes, notably its anterior segments. Both causal and correlation evidence showed prominent support of the superior longitudinal fasciculus to executive functions, notably to working memory. More specifically, strong evidence suggested that the second branch of the superior longitudinal fasciculus is crucial for all executive functions, especially for flexibility. Global results showed left lateralization for verbal tasks and right lateralization for executive tasks with visual demands. The frontal aslant tract potentially supports executive functions, however, additional evidence is needed to clarify whether its involvement in executive tasks goes beyond the control of language. Converging evidence indicates that a right-lateralized network of tracts connecting cortical and subcortical grey matter regions supports the performance of tasks assessing response inhibition, some suggesting a role for the right anterior thalamic radiation. Finally, correlation evidence suggests a role for the cingulum bundle in executive functions, especially in tasks assessing inhibition. We discuss these findings in light of current knowledge about the functional role of these tracts, descriptions of the brain networks supporting executive functions and clinical implications for individuals with brain tumours.

OBJECTIVE: Childhood maltreatment is extremely harmful to health, especially in relation to development of the psychiatric disorders throughout life. The objective of this study was to describe the prevalence and types of maltreatment in a sample of adolescent schoolchildren and to investigate associations between maltreatment types and anxiety and depressive symptoms, sociodemographic variables, and risk behaviors. The study also identified which variables were the greatest predictors of anxiety and depressive symptoms. METHODS: We conducted a cross-sectional study with a sample of 654 school students aged 11 to 17 years. We collected sociodemographic data and administered the Revised Child Anxiety and Depression Scale (RCADS-47) to measure anxiety and depressive symptoms as well as the Childhood Trauma Questionnaire (CTQ) to evaluate maltreatment and adverse experiences such as abuse and negligence during childhood and adolescence. Statistical analyses were conducted to estimate correlations between sociodemographic data, anxiety, depression, and types of maltreatment. A regression analysis was also conducted to identify maltreatment types that predict psychological symptoms. RESULTS: Emotional abuse and emotional neglect were the most prevalent types of maltreatment. Statistically, emotional abuse was the maltreatment type most strongly correlated with depression and anxiety and tended to co-occur with other types of maltreatment. Additionally, emotional and sexual abuse were the greatest predictors of anxiety and depression in adolescents. CONCLUSION: The above results reinforce the findings of previous studies in terms of understanding the effects of maltreatment. They identify emotional abuse as the main predictor of depressive and anxiety symptoms.

RESUMO
Lactic acid bacteria (LAB) have been documented as potential vitamin B12 producers and may constitute an exogenous source of cobalamin for the microalga Chlorella vulgaris, which has been described as being able to perform vitamin uptake. Hence, there is an interest in discovering novel B12-producing probiotic LAB. Therefore, the purpose of the current work was to perform a phenotype-genotype analysis of the vitamin B12 biosynthesis capacity of LAB isolated from C. vulgaris bioreactors, and investigate their probiotic potential. Among the selected strains, Lactococcus lactis E32, Levilactobacillus brevis G31, and Pediococcus pentosaceus L51 demonstrated vitamin B12 biosynthesis capacity, with the latter producing the highest (28.19 ± 2.27 pg mL-1). The genomic analysis confirmed the presence of pivotal genes involved in different steps of the biosynthetic pathway (hemL, cbiT, cobC, and cobD). Notably, P. pentosaceus L51 was the only strain harboring cobA, pduU, and pduV genes, which may provide evidence for the presence of the cobalamin operon. All strains demonstrated the capability to withstand harsh gastrointestinal conditions, although P. pentosaceus L51 was more resilient. The potential for de novo cobalamin biosynthesis and remarkable probiotic features highlighted that P. pentosaceus L51 may be considered the most promising candidate strain for developing high-content vitamin B12 formulations.

High-grade glioma (HGG) is associated with several external and internal stressors that may induce mood alterations at all stages of the disease. Symptoms of depression and anxiety in persons with glioma have multifactorial etiology and require active follow-up. We reviewed the literature data on the prevalence, mechanisms likely involved in the etiology of mood alterations in persons with HGG and psychosocial interventions found beneficial in treating these symptoms. We also investigated the prevalence and clinical variables that could increase the risk of depression and anxiety symptoms in a group of patients with HGG at two disease time-points: after surgery, before and 1 year after chemoradiotherapy. Literature findings revealed complex mechanisms underlying these symptoms and highlighted the importance of providing early access to palliative care. Our results show a high rate of anxiety and depression symptoms in the first stage of the disease and increased concomitance of these symptoms at the 1-year follow-up. Depression and anxiety symptoms at 1 year after the end of chemoradiotherapy were associated with the presence of symptoms at the first stage of the disease and tumor progression. Antiepileptic drugs and corticosteroid intake did not increase the risk of depressive and anxious symptoms among patients. Active management of mood alterations is an essential part of the care and contributes to patients' well-being and quality of life.
RESUMO
INTRODUCTION: The corpus callosum (CC) is frequently involved in primary central nervous system lymphomas (PCNSLs). In this cohort study, we described the neurocognition of patients with PCNSL-CC and its posttherapeutic evolution. METHODS: Immunocompetent patients with PCNSL-CC were identified retrospectively at the Pitié-Salpêtrière Hospital. We described their clinical presentation. Neuropsychological test scores (MMSE; digit spans; Free and Cued Selective Reminding Test; Image Oral Naming Test; Frontal Assessment Battery; Trail Making Test; Stroop and verbal fluency tests; Rey's Complex Figure test) and factors impacting them were analyzed. RESULTS: Twenty-seven patients were included (median age: 67 years, median Karnofsky Performance Status: 70); cognitive impairment and balance disorders were present in 74% and 59%, respectively. At diagnosis, neuropsychological test results were abnormal for global cognitive efficiency (63% of patients), memory (33-80% depending on the test) and executive functions (44-100%). Results for visuospatial and language tests were normal. All patients received high-dose methotrexate-based polychemotherapy, followed in one patient by whole-brain radiotherapy; 67% of patients achieved complete response (CR). With a median follow-up of 48 months (range 6-156), patients in CR had persistent abnormal test results for global cognitive efficiency in 17%, executive function in 18-60%, depending on the test, and memory in 40-60%. Splenium location and age ≥ 60 years were significantly associated with worse episodic memory scores throughout the follow-up. CONCLUSIONS: PCNSL-CC is associated with frequent cognitive dysfunctions, especially memory impairment, which may recover only partially despite CR and warrant specific rehabilitation. Older age (≥ 60) and splenium location are associated with worse neurocognitive outcomes.

AIM: Bring to discussion spiritual leadership and workplace spirituality on a health care system that faces constant challenges and seeks constant adaptations, as a way to guarantee nurses' well-being and quality of care. BACKGROUND: The work environment has shown to have impact on staff well-being. Workplace spirituality relates to sense of belonging, motivation and commitment. A spiritual leadership is fundamental to develop workplace spirituality. EVALUATION: Starting from literature, a reflection on the theme was carried out based on the results of the development of spiritual leadership and workplace spirituality in health care institutions, in professionals and in patients. KEY ISSUES: Nurses have spiritual needs which need to be also addressed in order to promote the sense of identification with the institutions' vision and goals. A relation between spiritual leadership, workplace spirituality and subjective well-being is often found in literature, and this is critical evidence towards new management and leadership dynamics and models in health care institutions that should integrate workplace spirituality. CONCLUSION: Nursing leaders are responsible for workplace spirituality facilitation. Nursing leadership and workplace spirituality seem both an answer and way to the change of health institutions management paradigm, but more studies are needed to inform this change in practice. IMPLICATIONS FOR NURSING MANAGEMENT: Workplace spirituality must be promoted in all health care institutions, aiming the humanization of care and teams. Nursing leaders must have spiritual competences and must include the promotion of workplace spirituality in daily agenda as a foundational area in management. The health care institutions' managers should consider the best leaders who should facilitate workplace spirituality.

INTRODUCTION: Cognitive impairment is frequent in patients with high-grade glioma and requires cognitive follow-up. Cognitive screening tools such as the Montreal Cognitive Assessment (MoCA) have been used to assess cognition in these patients. Here we assessed the sensitivity of the MoCA in screening for cognitive impairment in a cohort of 156 patients with newly-diagnosed high-grade glioma, after surgery and before radiochemotherapy. METHODS: We assessed cognitive performance with the MoCA and a neuropsychological battery. Cognitive scores were analyzed in terms of a previously validated framework designed to control false positives and data for 1003 control participants from the GRECOGVASC study. After comparison of performance on the tests, we used stepwise logistic regression to produce a cognitive summary score from the neuropsychological battery. Then we analyzed sensitivity and specificity of the MoCA with receiver operator characteristic (ROC) curve analysis. RESULTS: Both raw and adjusted MoCA scores showed only moderate sensitivity. The area under the ROC curve was 0.759 (95% CI 0.703-0.815) for the raw score and 0.788 (95% CI 0.734-0.842) for the adjusted score. Optimal discrimination was obtained with a raw score ≤ 25 (sensitivity: 0.526; specificity: 0.832; positive predictive value: 0.2; negative predictive value: 0.96) and an adjusted score - 0.603 (sensitivity: 0.716; specificity: 0.768; positive predictive value: 0.24; negative predictive value: 0.96). CONCLUSION: The moderate sensitivity of MoCA indicates that it is not a suitable screening tool for detecting cognitive impairment in patients with newly-diagnosed high-grade glioma.

OBJECTIVE: To evaluate the interrelationships between childhood maltreatment, life satisfaction (LS), and depressive symptoms, and to investigate LS as a mediating factor in the association between childhood maltreatment and depressive symptoms. METHODS: The sample consisted of 342 adolescents, aged 11 to 17 years (mean = 13.3, SD = 1.52 years), recruited from a public school in Salvador, Brazil. Participants filled out instruments for the collection of sociodemographic data and evaluation of childhood maltreatment, LS, and depressive symptoms. Structural equation modeling (SEM) was used to evaluate the mediating effect of LS. RESULTS: We detected significant negative correlations between childhood maltreatment and LS and between LS and depressive symptoms. We observed a significant positive correlation between childhood maltreatment and depressive symptoms. LS partially mediated the association between childhood maltreatment and depressive symptoms, mitigating the impact of maltreatment. CONCLUSION: LS played an important mediating role in the association between childhood maltreatment and depressive symptoms. Longitudinal studies are recommended to fully elucidate these associations, reinforcing the need for attention and care of this vulnerable population.

Sustainable management of insular beaches, that are critical to tourism-based economies, depends on sound understanding of coastal evolution drivers. However, interconnections among geological, oceanographical, biological and human key-drivers of coastal change, operating at relevant spatial and temporal scales, remains poorly understood. This work aims at understanding and quantifying the main drivers of insular beaches evolution using a past-to-future sediment budget approach, and to address future coastal impacts raised by anthropogenic interventions and climate change. This approach was developed in Porto Santo's beach from the early 20th century to the middle 21st century. Results show that anthropic activities undertaken during the late 20th century perturbed the existing long-term (natural) coastal stability. They caused significant reduction of the main sediment source (river sediment yield) and increased sediment sinks (e.g. sediment extraction from beach, harbour sedimentation). Altogether, this resulted in the onset of an erosive trend that persists until present. Projecting patterns of coastal change into the forthcoming decades strongly depends on sediment management strategies. We show that the adoption of a neutral strategy (i.e. compensating for anthropogenic-induced losses with beach nourishment) will not be enough to cease beach erosion, given the negative impacts related to acceleration of future sea level rise. Still, maintenance of the socioeconomic values of Porto Santo's beach can be achieved by triggering positive anthropic influences on its sediment budget. The past-to-future sediment budget approach proposed herein provided a unified perspective on the evolution of the main drivers of coastal change and simultaneously offers foundations for adaptations strategies aiming at increasing sustainability of insular beaches.
RESUMO
Life expectancy of patients treated for brain tumors has lengthened due to the therapeutic improvements. Cognitive impairment has been described following brain radiotherapy, but the mechanisms leading to this adverse event remain mostly unknown. Technical evolutions aim at enhancing the therapeutic ratio. Sparing of the healthy tissues has been improved using various approaches; however, few dose constraints have been established regarding brain structures associated with cognitive functions. The aims of this literature review are to report the main brain areas involved in cognitive adverse effects induced by radiotherapy as described in literature, to better understand brain radiosensitivity and to describe potential future improvements.

Introdução: as ceratites são infecções da córnea, que acontecem pós-trauma, cirúrgico ou não, ou em indivíduos imunossuprimidos e que podem ter como agente etiológico micobactérias não-tuberculosas (MNTs). O diagnóstico das ceratites por MNTs é feito pelos aspectos clínicos em associação à identificação do patógeno. Não existe um consenso na literatura com relação ao tratamento farmacológico. Objetivos: o objetivo primário é identificar as opções terapêuticas farmacológicas para ceratites por MNTs e, o secundário, descrever os aspectos clínicos dessa infecção. Metodologia: um total de 214 artigos foram encontrados através da pesquisa nas fontes CAPES, LILACS, PUBMED e Biblioteca Cochrane, utilizando-se as combinações de palavras chave: "ceratite" e "micobactérias não-tuberculosas, destes, após o uso dos critérios de exclusão, 4 artigos foram selecionados. Resultados: partindose das 4 publicações selecionadas foram reunidos 5 casos clínicos, todos com história de trauma corneano, cirúrgico ou não. Os 5 pacientes foram submetidos à técnica diagnóstica não-invasiva e em todos foi identificada MNT. Os tratamentos farmacológicos foram feitos com antimicrobianos das classes das quinolonas, aminoglicosídeos e macrolídeos. Em um dos casos foi usado um corticoide e em dois foi feita associação com anti-inflamatório não-esteroide. Conclusão: o tratamento farmacológico da ceratite por MNTs é de longo prazo, e, neste estudo, variou de 3 semanas a 6 meses. Os quimioterápicos usados são os aminoglicosídeos, macrolídeos e quinolonas e, em alguns casos, a combinação destes. O uso de anti-inflamatórios não-esteroidais e esteroidais não é consensual. Quanto aos aspectos clínicos, observam-se características comuns a outras ceratites infecciosas

Childhood maltreatment is a key predictor of mental health problems across the life span. Yet, how maltreatment types independently and jointly influence the risk for psychiatric problems remains unclear. The aim of the study was two-fold: first, to replicate recent findings regarding the impact of maltreatment types on youth psychiatric symptoms, based on a Brazilian sample of high-risk adolescents (nâ¯=â¯347; age rangeâ¯=â¯11-17â¯yrs), and second, to extend existing findings by examining whether this relationship is mediated by bullying victimization and/or perpetration. Measures included self-report ratings of childhood maltreatment and peer victimization, as well as multi-informant reports of internalizing and externalizing symptoms. Consistent with prior research, we found that: (i) maltreatment types often co-occurred; (ii) there was a linear association between number of maltreatment types experienced and symptom severity (i.e. cumulative effect); and (iii) emotional abuse emerged as the most consistent independent predictor of poor mental health across domains, raters, and gender. Additionally, this study extends previous findings by showing that the influence of maltreatment on psychiatric outcomes is partially mediated by peer victimization, but not by bullying perpetration. In conclusion, these findings expand our understanding of the heterogeneity in individual responses to maltreatment as well as highlighting emotional abuse as an important predictor of poor mental health.

A ausência ou perda da papila interdental cria deficiência estética, problemas fonéticos, impactação alimentar e gera muita expectativa ao paciente. Até o momento, o tratamento da ausência ou perda da papila interdental tem sido mal sucedido e não há estudos que indiquem que a regeneração da papila é um resultado previsível. O objetivo deste estudo foi avaliar a efetividade da injeção de gel de ácido hialurônico de origem não animal na redução ou eliminação da deficiência de papila entre dentes naturais comparativamente ao tratamento por meio de enxerto de tecido conjuntivo subepitelial. Foram avaliados neste estudo 20 sítios de 6 pacientes de ambos os sexos, com idade variável de 29 a 62 anos, apresentando deficiência de papila entre dentes naturais, na região anterior superior, em pelo menos dois dentes. Os 20 sítios tratados foram aleatoriamente divididos em dois grupos, de acordo com o tratamento para correção da deficiência de papila por meio de enxerto de tecido conjuntivo subepitelial (grupo controle) ou por meio de injeção de gel de ácido hialurônico (grupo teste). Um examinador único, calibrado, avaliou a distância da ponta da papila ao ponto de contato com auxílio de sonda periodontal milimetrada antes e aos 1, 3 e 6 meses após o tratamento. Além disso, foram investigados, nos sítios tratados, as medidas de profundidade de sondagem, nível de inserção, índice de sangramento do sulco, índice de placa, distância do ponto de contato à crista óssea alveolar, distância da ponta da papila à crista óssea alveolar e largura da papila. Os resultados demonstraram que aos 6 meses de pósoperatório o percentual de mudança na altura da papila foi maior no grupo teste (14,94% ± 21,35%) do que no grupo controle (-1,39% ± 31,46%), entretanto sem diferenças significantes entre os grupos (p> 0.05). Não houve variação estatisticamente significante na largura da papila antes e aos 4 meses após o tratamento nos grupos teste (p= 0.09) e controle (p= 0.16), assim como não houve variação significativa na distância entre a ponta da papila e a crista óssea alveolar. Houve melhora significativa do Índice de Estética Rosa (IER) observado aos 6 meses de acompanhamento em comparação com a condição inicial no grupo teste (p= 0.0078; Wilcoxon), enquanto que não houve mudança significativa no IER observado no grupo controle aos 6 meses de acompanhamento (p= 0.35). Os resultados obtidos permitiram concluir que o tratamento da deficiência de papila por meio de injeção de gel de ácido hialurônico promove melhora da deficiência de papila, similar aos resultados obtidos com o tratamento por meio de enxerto de tecido conjuntivo subepitelial, porém com melhora estética significativa relacionada especialmente às características de cor e textura do tecido relativamente aos tecidos moles adjacentes.(AU)
The absence or loss of interdental papilla creates an esthetic deficiency, phonetic problems and food impaction and generates a lot of expectation for the patient. Until now, the treatment for absence or loss of interdental papilla is unsuccessful e and there are no researches that show that the papilla regeneration is a predictable outcome. The aim of this study was to evaluate the effectivity of a non-animal originated hyaluronic acid injection in the reduction or elimination of papilla deficiency between natural teeth in comparison to a sub epithelial connective tissue graft treatment. The analysis was made on 20 sites in 6 patients, both genders, 29 - 62 years, showing deficiency in the papilla between natural teeth in the upper anterior region in at least two teeth. The 20 sites treated were randomly divided into two groups, according to the treatment by subepithelial connective tissue graft (control group) or by hyaluronic acid injection (test group). A single calibrated examiner evaluated the distance between the tip of the papilla to the contact point using a graduated periodontal probe before the treatment and 1, 3 and 6 months after it. Besides, it were investigated probing pocket depth, clinical attachment level, gingival bleeding index, plaque index, distance from papilla to alveolar crest, distance from contact point to alveolar crest and width of the papilla. The results showed that 6 months after the procedure, the percentage of change in the papilla level was higher in the test group (14,94% ± 21,35%) than in the control group (-1,39% ± 31,46%), though not statistically significant (p>0.05). There was no significant difference variation in the width of the papilla before and 4 months after the treatment in test group (p=0.09) and control group (p=0.16), and there was no significant difference variation in the distance between the tip of the papilla and the alveolar bone crest. There was significant improvement of the Pink Esthetic Score (PES) after 6 months in comparison to the initial condition in test group (p=0.0078; Wilcoxon), while there was no significant difference in the PES in control group 6 months after treatment (p=0.35). The results allow to conclude that the treatment for of the papilla deficiency using hyaluronic acid injection promotes improvement, similar to the results of the sub epithelial connective tissue graft treatment, but with significant esthetic improvement related specially to the color and texture characteristics of the adjacent soft tissues.(AU)

UNLABELLED: GRID-HAMD is a semi-structured interview guide developed to overcome flaws in HAM-D, and has been incorporated into an increasing number of studies. OBJECTIVES: Carry out the transcultural adaptation of GRID-HAMD into the Brazilian Portuguese language, evaluate the inter-rater reliability of this instrument and the training impact upon this measure, and verify the raters' opinions of said instrument. METHODS: The transcultural adaptation was conducted by appropriate methodology. The measurement of inter-rater reliability was done by way of videos that were evaluated by 85 professionals before and after training for the use of this instrument. RESULTS: The intraclass correlation coefficient (ICC) remained between 0.76 and 0.90 for GRID-HAMD-21 and between 0.72 and 0.91 for GRID-HAMD-17. The training did not have an impact on the ICC, except for a few groups of participants with a lower level of experience. Most of the participants showed high acceptance of GRID-HAMD, when compared to other versions of HAM-D. CONCLUSION: The scale presented adequate inter-rater reliability even before training began. Training did not have an impact on this measure, except for a few groups with less experience. GRID-HAMD received favorable opinions from most of the participants.
RESUMO
This study assessed the effect of the Body Rhythmics (BRIM) on actors' attentional processes. BRIM is a combination of exercises using numbers and rules that enact musical parameters in the moving body through displacements. Male actors (N = 22) participated in the study: 7 in the BRIM (Study) group and 15 in the Control group (groups were equivalent on mean Raven's IQ). The Continuous Performance Test (CPT-II) was administered before and after an intensive period of BRIM training. There was no significant difference on the CPT-II before training. Group results for before vs after training showed a significant difference for reaction time for the Study group. There was also a trend to increased errors of commission in the Study group after BRIM training.
