RESUMO
This manuscript reports for the first time a heterogenous catalytic route to monoglycerides (MAGs) from microalgal oil. Microalgae is an important biomass source with high-value applications, such as food ingredients with essential fatty acids. To date, the glycerolysis of microalgae has only been investigated for a microbial oil (Schizochytrium sp.) using enzyme catalysis. However, the use of enzymes on a large scale is currently economically impeditive and requires highly selective lipases. In this study, metal oxides were screened and the reaction conditions optimized for rapeseed oil. The optimized conditions were then used to investigate the production of MAGs from Scenedesmus sp. microalga. The most promising catalyst was found to be MgO/KOH, which gave a 44 % yield. Comparing two reaction systems (low temperature 70 °C/atmospheric pressure and high temperature at 200 °C/20â bar), it was found that the latter has a superior performance. Due to the stability of the product in air, the presence of an inert atmosphere is essential to achieve high yields.
RESUMO
Arthrogryposis multiplex congenita (AMC) is a group of conditions characterized by multiple joint contractures. This rare disorder causes stiffness of joints, limiting the range of motion and negatively impacting activities of daily living (ADL). This case reports a 45-year-old male with AMC who was referred to physical medicine and rehabilitation (PMR). He had a limited range of movement in multiple joints and global muscle weakness. However, ADL were feasible, including walking. The patient had an unsteady barefoot gait, causing claudication, which improved significantly with adapted shoes. The primary goal of treatment is to improve the quality of life (QoL), and proper management should be promptly initiated. AMC requires a multidisciplinary approach to care with three mainstays of treatment: rehabilitation, orthoses, and corrective surgeries. Patients should be followed up periodically by their family doctors, and PMR evaluations and rehabilitation should be provided as needed. An orthopedic surgery consultation may be required for surgical interventions to provide optimal outcomes and augment the QoL.
RESUMO
OBJECTIVES: To evaluate the prevalence, magnitude, and potential determinants of work productivity impairment in patients with Behçet's Syndrome (BS), focusing on the role of irreversible organ damage. METHODS: A post-hoc analysis of the BS overall damage index (BODI) prospective validation study was performed. Demographics and clinical features were recorded in all patients. The Work Productivity and Activity Impairment: General Health (WPAI: GH) questionnaire was administered to assess the work limitation and the BODI to measure organ damage. The independent effect of BS features on WPAI: GH outcomes was evaluated by regression analysis. RESULTS: Out of 148 patients, 34.5% were unemployed, with age (OR 1.035) and BODI score (OR 1.313 for 1-unit increase) as the only factors significantly (p< 0.05) associated with the unemployment state. An overall work impairment was reported in about 64.2% of the employed patients. Indeed, 22.7% reported missing work h due to their health (absenteeism), with a mean time loss of 34.4%; whereas 60.2% declared a reduced performance at work because of their health (presenteeism), with a mean productivity impairment of 45.4%. Ocular damage was associated with absenteeism (ß 0.225); female sex (ß 0.260), physician global assessment of disease activity (ß 0.502) and an increased BODI score (ß 0.166 for 1-point increase) with presenteeism; fibromyalgia (ß 0.246), physician global assessment (ß 0.469), and musculoskeletal damage (ß 0.325) with overall work impairment. CONCLUSIONS: Disease activity and organ damage accrual remarkably affect work productivity in BS patients. Achieving remission and preventing damage accrual are crucial and complementary objectives.
RESUMO
Lung cancer is the second most common cancer worldwide and remains the first cause of cancer death. The diagnosis of lung cancer is mostly made following evaluation for respiratory signs and symptoms but sometimes the first presentation may be atypical. Some symptoms may be related to the invasion of adjacent structures and others caused by an autoimmune-mediated process when cross-reactivity between tumor antigens and normal nervous tissues is responsible for paraneoplastic syndromes. We present a case of a young woman with a smoking history who first manifested with two uncommon presentations of lung cancer: a paraneoplastic neurological syndrome and a hemorrhagic pericardial effusion with cardiac tamponade.
RESUMO
Parkinson's disease (PD) is the most common movement disorder, characterized by the progressive loss of dopaminergic neurons from the nigrostriatal system. Currently, there is no treatment that retards disease progression or reverses damage prior to the time of clinical diagnosis. Mesenchymal stem cells (MSCs) are one of the most extensively studied cell sources for regenerative medicine applications, particularly due to the release of soluble factors and vesicles, known as secretome. The main goal of this work was to address the therapeutic potential of the secretome collected from bone-marrow-derived MSCs (BM-MSCs) using different models of the disease. Firstly, we took advantage of an optimized human midbrain-specific organoid system to model PD in vitro using a neurotoxin-induced model through 6-hydroxydopamine (6-OHDA) exposure. In vivo, we evaluated the effects of BM-MSC secretome comparing two different routes of secretome administration: intracerebral injections (a two-site single administration) against multiple systemic administration. The secretome of BM-MSCs was able to protect from dopaminergic neuronal loss, these effects being more evident in vivo. The BM-MSC secretome led to motor function recovery and dopaminergic loss protection; however, multiple systemic administrations resulted in larger therapeutic effects, making this result extremely relevant for potential future clinical applications.

Mesenchymal stem cells (MSCs) hold promising therapeutic potential in several clinical applications, mainly due to their paracrine activity. The implementation of future secretome-based therapeutic strategies requires the use of easily accessible MSCs sources that provide high numbers of cells with homogenous characteristics. MSCs obtained from induced pluripotent stem cells (iMSCs) have been put forward as an advantageous alternative to the gold-standard tissue sources, such as bone marrow (BM-MSCs). In this study, we aimed at comparing the secretome of BM-MSCs and iMSCs over long-term culture. For that, we performed a broad characterization of both sources regarding their identity, proteomic secretome analysis, as well as replicative senescence and associated phenotypes, including its effects on MSCs secretome composition and immunomodulatory action. Our results evidence a rejuvenated phenotype of iMSCs, which is translated into a superior proliferative capacity before the induction of replicative senescence. Despite this significant difference between iMSCs and BM-MSCs proliferation, both untargeted and targeted proteomic analysis revealed a similar secretome composition for both sources in pre-senescent and senescent states. These results suggest that shifting from the use of BM-MSCs to a more advantageous source, like iMSCs, may yield similar therapeutic effects as identified over the past years for this gold-standard MSC source.

BACKGROUND: This study aimed to investigate the trajectory of damage accrual, associated factors, and impact on health-related quality of life (HR-QoL) in a multicenter cohort of patients with Behçet's syndrome (BS) over 2 years of follow-up. METHODS: Patients recruited in the BS Overall Damage Index (BODI) validation study were prospectively monitored for 2 years and assessed for damage accrual, defined as an increase ≥1 in the BODI score, and HR-QoL was evaluated by the SF-36 questionnaire. Logistic and multiple linear regression models were built to determine factors associated with damage accrual and impairment in the different SF-36 domains. RESULTS: During follow-up, 36 out of 189 (19.0%) patients had an increase ≥1 in the BODI score with a mean (SD) difference of 1.7 (0.8) (p <0.001). The incidence rate of damage accrual was stable over time, regardless of the disease duration. Out of 61 new BODI items, 25 (41.0%) were considered related to glucocorticoid (GC) use. In multivariate analysis, duration of GC therapy (OR per 1-year 1.15, 95% CI 1.07-1.23; p <0.001) and occurrence of ≥1 disease relapse (OR 3.15, 95% CI 1.09-9.12; p 0.038) were identified as predictors of damage accrual, whereas the use of immunosuppressants showed a protective effect (OR 0.20, 95% CI 0.08-0.54, p<0.001). Damage accrual was independently associated with the impairment of different physical domains and, to a greater extent, in emotional domains of the SF-36 questionnaire. Female sex, higher disease activity, and fibromyalgia were also significantly associated with impairment in HR-QoL. CONCLUSION: In BS, organ damage accrues over time, also in long-standing disease, resulting in an impairment of the perceived physical and mental health. Adequate immunosuppressive treatment, preventing disease flares and minimizing exposure to GCs have a crucial role in lowering the risk of damage accrual.

Abstract Objective To assess obstetric/puerperal/neonatal outcomes in an inflammatory bowel disease (IBD) population and to analyze disease characteristics that may be associated to adverse outcomes. Methods Retrospective descriptive analysis including 47 pregnant women with IBD (28 with Crohn's disease - CD and 19 with ulcerative colitis - UC) who delivered between March 2012 and July 2018 in a tertiary hospital. We reviewed clinical records to extract demographic information, previous medical history, disease subtype, activity, severity, treatment, and obstetric, puerperal, and neonatal outcome measures. Results Obstetric and neonatal complications (composite outcomes) occurred in 55.3% and 14.6% of the IBD population, respectively, and were more frequent in UC patients. Preterm birth (PTB), preeclampsia, anemia, low birth weight (LBW), and neonatal death were also more frequent in UC patients. The rate of postpartum hemorrhage (PPH) was 14.9%, and it was higher in CD patients. Women with active IBD had more obstetric/neonatal adverse outcomes (fetal growth restriction and LBW in particular) and cesarean sections. Patients with medicated IBD had less obstetric/neonatal complications (PTB and LBW in specific) and cesarean sections but more PPH. Conclusion Women with IBD may have an increased risk of obstetric/puerperal/neonatal adverse outcomes. Ulcerative colitis patients had more obstetric and neonatal complications, whereas PPH was more frequent if CD patients. Other disease characteristics were considered, which allowed a better understanding of their possible influence. Although more research is needed, this work reinforces the importance of adequate surveillance to allow prompt recognition and treatment of complications.
Resumo Objetivo Avaliar os desfechos obstétricos/puerperais/neonatais em uma população com doença inflamatória intestinal (DII) e analisar as características da doença, que podem estar associadas a desfechos adversos. Métodos Análise descritiva retrospectiva incluindo 47 gestantes com DII (28 com doença de Crohn - DC e 19 com retocolite ulcerativa - RCU) que deram à luz entre março de 2012 e julho de 2018 em um hospital terciário. Revisamos os registros clínicos para extrair informações demográficas, histórico médico prévio, subtipo da doença, atividade, gravidade, tratamento e medidas de resultados obstétricos, puerperais e neonatais. Resultados As complicações obstétricas e neonatais (desfechos compostos) ocorreram em 55,3% e 14,6% da população com DII, respectivamente; e foram mais frequentes em pacientes com RCU. Nascimento prematuro (PTB), pré-eclâmpsia, anemia, baixo peso ao nascer (BPN) e óbito neonatal também foram mais frequentes em pacientes com RCU. A taxa de hemorragia pós-parto (HPP) foi de 14,9% e foi maior em pacientes com DC. Mulheres com DII ativa tiveram mais desfechos obstétricos/neonatais adversos (restrição de crescimento fetal e BPN em particular) e cesarianas. Pacientes com DII medicada tiveram menos complicações obstétricas/neonatais (PTB e BPN em específico) e cesarianas, mas mais HPP. Conclusão Mulheres com DII podem ter um risco aumentado de desfechos adversos obstétricos/puerperais/neonatais. As pacientes com RCU apresentaram mais complicações obstétricas e neonatais, enquanto a HPP foi mais frequente em pacientes com DC. Outras características da doença foram consideradas, o que permitiu uma melhor compreensão de sua possível influência. Embora mais pesquisas sejam necessárias, este trabalho reforça a importância de uma vigilância adequada para permitir o reconhecimento e o tratamento imediatos das complicações.

TET enzymes (TET1-3) are dioxygenases that oxidize 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC) and are involved in the DNA demethylation process. In line with the observed 5hmC abundance in the brain, Tet genes are highly transcribed, with Tet3 being the predominant member. We have previously shown that Tet3 conditional deletion in the brain of male mice was associated with anxiety-like behavior and impairment in hippocampal-dependent spatial orientation. In the current study, we addressed the role of Tet3 in female mice and its impact on behavior, using in vivo conditional and inducible deletion from post-mitotic neurons. Our results indicate that conditional and inducible deletion of Tet3 in female mice increases anxiety-like behavior and impairs both spatial orientation and short-term memory. At the molecular level, we identified upregulation of immediate-early genes, particularly Npas4, in both the dorsal and ventral hippocampus and in the prefrontal cortex. This study shows that deletion of Tet3 in female mice differentially affects behavioral dimensions as opposed to Tet3 deletion in males, highlighting the importance of studying both sexes in behavioral studies. Moreover, it contributes to expand the knowledge on the role of epigenetic regulators in brain function and behavioral outcome.

The axonal growth-restrictive character of traumatic spinal cord injury (SCI) makes finding a therapeutic strategy a very demanding task, due to the postinjury events impeditive to spontaneous axonal outgrowth and regeneration. Considering SCI pathophysiology complexity, it has been suggested that an effective therapy should tackle all the SCI-related aspects and provide sensory and motor improvement to SCI patients. Thus, the current aim of any therapeutic approach for SCI relies in providing neuroprotection and support neuroregeneration. Acknowledging the current SCI treatment paradigm, cell transplantation is one of the most explored approaches for SCI with mesenchymal stem cells (MSCs) being in the forefront of many of these. Studies showing the beneficial effects of MSC transplantation after SCI have been proposing a paracrine action of these cells on the injured tissues, through the secretion of protective and trophic factors, rather than attributing it to the action of cells itself. This manuscript provides detailed information on the most recent data regarding the neuroregenerative effect of the secretome of MSCs as a cell-free based therapy for SCI. The main challenge of any strategy proposed for SCI treatment relies in obtaining robust preclinical evidence from in vitro and in vivo models, before moving to the clinics, so we have specifically focused on the available vertebrate and mammal models of SCI currently used in research and how can SCI field benefit from them.

BACKGROUND: Sirolimus constitutes a safe and effective treatment for cardiac manifestations of tuberous sclerosis complex (TSC) in children but only four cases describing prenatal treatment of rhabdomyomas with mTOR inhibitors have been published. CASE: In this case, sirolimus was initiated at 26 weeks´ gestation in a pregnant woman with TSC with a fetus with a large rabdomyoma conditioning severe arrythmia. There was a significant reduction in the tumor size with ongoing treatment and a partial reversion of the arrythmia. CONCLUSION: m-TOR inhibitors can be considered for severe cases of fetal rhabdomyomas with poor prognosis given its potencial benefits.

Corynebacterium striatum (C. striatum) is a skin commensal agent, rarely described as a cause of infective endocarditis. We describe a case of a 48-year-old man, with multiple comorbidities with cardiac resynchronization therapy defibrillator (CRT-D) device implanted 1 year before. A cardiac device-related infective endocarditis (CDRIE) due to C. striatum, with vegetations in the tricuspid valve adjacent to the electrode lead and concomitant lumbar spondylodiscitis were diagnosed. The patient was treated initially with a 6-week course of vancomycin with sterile blood cultures and reduction of inflammatory parameters. Surgery was refused at this stage. Six weeks later, he was readmitted due to C. striatum bacteriemia recurrence, with vegetations adhering to the electrode wire, being treated with daptomycin 10mg/kg body weight, after presenting renal toxicity to vancomycin. CRT-D device was removed with implantation of epicardial cardiac resynchronization therapy pacemaker (CRT-P). To our knowledge, this might be the first description of C. striatum CDRIE in a patient with a CRT-D. In the five cases described in the literature of CDRIE by this agent, early removal of the pacemaker was performed with good results. In this case, the device was removed only after failure of medical treatment alone.
RESUMO
A 29-year-old woman presented to the emergency department with red eyes and hypoacusia since the previous weeks associated with a sudden right facial palsy. Ophthalmologic examination revealed bilateral uveitis and lumbar puncture was compatible with aseptic meningitis. Thoracic computed tomography scan showed pulmonary nodules and mediastinal and hilar lymphadenopathy. Bronchoalveolar lavage revealed a CD4/CD8 ratio of 8, and lymph node biopsy confirmed non-caseating granulomas. The diagnosis of sarcoidosis with ocular, pulmonary, and neurologic involvement was made. Due to sarcoidosis severity at presentation, the patient was started on systemic steroids and methotrexate with improvement. Sarcoidosis involvement of the central nervous system is a rare condition (5-10%) but can be the first manifestation of the disease. Its presentation can be heterogeneous; therefore, symptoms are frequently devalued by patients and physicians, leading to a late diagnosis and permanent damage. Clinicians' awareness is crucial to early diagnosis and treatment.
RESUMO
Primary cardiac angiosarcoma is a rare malignant neoplasm and occurs most frequently in middle-aged males. It has an aggressive nature, with highly variable clinical features, which results in delayed diagnosis and high mortality. We report a 19-year-old man presented to the ED with a three-month history of hemoptysis and one-week history of anterior chest pain. Additionally, an aortic diastolic murmur grade II/VI was found on physical examination. Thoracic CT scan revealed bilateral dispersed hypodense pulmonary nodes with peripheral halo, alveolar densification, and pericardial effusion. The transthoracic echocardiogram confirmed sizeable pericardial effusion and bicuspid aortic valve, without other significant findings. A pericardiocentesis removed 1300 mL of hemorrhagic fluid, consistent with an exudate without malignant cells. Both cardiac magnetic resonance and transesophageal echocardiogram revealed a large mass on the right atrium's anterior wall. Mass biopsy was performed, revealing malignant cardiac angiosarcoma. The biopsy of the lung lesions was compatible with lung metastasis of primary cardiac angiosarcoma. The patient was submitted to palliative chemotherapy but died 12 months after the diagnosis.
RESUMO
The crosstalk between glial cells and neurons represents an exceptional feature for maintaining the normal function of the central nervous system (CNS). Increasing evidence has revealed the importance of glial progenitor cells in adult neurogenesis, reestablishment of cellular pools, neuroregeneration, and axonal (re)myelination. Several types of glial progenitors have been described, as well as their potentialities for recovering the CNS from certain traumas or pathologies. Among these precursors, glial-restricted precursor cells (GRPs) are considered the earliest glial progenitors and exhibit tripotency for both Type I/II astrocytes and oligodendrocytes. GRPs have been derived from embryos and embryonic stem cells in animal models and have maintained their capacity for self-renewal. Despite the relatively limited knowledge regarding the isolation, characterization, and function of these progenitors, GRPs are promising candidates for transplantation therapy and reestablishment/repair of CNS functions in neurodegenerative and neuropsychiatric disorders, as well as in traumatic injuries. Herein, we review the definition, isolation, characterization and potentialities of GRPs as cell-based therapies in different neurological conditions. We briefly discuss the implications of using GRPs in CNS regenerative medicine and their possible application in a clinical setting. MAIN POINTS: GRPs are progenitors present in the CNS with differentiation potential restricted to the glial lineage. These cells have been employed in the treatment of a myriad of neurodegenerative and traumatic pathologies, accompanied by promising results, herein reviewed.

A 19 years-old woman, on her 17th week of pregnancy presented to the emergency department with thoracic pain and vomiting. An empyema was diagnosed and she was transferred to a tertiary hospital for treatment. After drainage of the empyema a mediastinal mass was detected and a thoracic MRI revealed a multicystic lesion of the anterior mediastinum, causing cardiac and left lung compression, suggestive of a complicated teratoma. After a multidisciplinary discussion involving pulmonology, radiology, obstetrics and thoracic surgery, she was operated successfully by clamshell incision. A mature complicated teratoma was resected and a left pleurectomy/decortication performed. She was discharged on day 17 with no obstetrical or respiratory symptoms..

Epidemiologic studies have provided compelling evidence that prenatal stress, through excessive maternal glucocorticoids exposure, is associated with psychiatric disorders later in life. We have recently reported that anxiety associated with prenatal exposure to dexamethasone (DEX, a synthetic glucocorticoid) correlates with a gender-specific remodeling of microglia in the medial prefrontal cortex (mPFC), a core brain region in anxiety-related disorders. Gender differences in microglia morphology, the higher prevalence of anxiety in women and the negative impact of anxiety in cognition, led us to specifically evaluate cognitive behavior and associated circuits (namely mPFC-dorsal hippocampus, dHIP), as well as microglia morphology in female rats prenatally exposed to dexamethasone (in utero DEX, iuDEX). We report that iuDEX impaired recognition memory and deteriorated neuronal synchronization between mPFC and dHIP. These functional deficits are paralleled by microglia hyper-ramification in the dHIP and decreased ramification in the mPFC, showing a heterogeneous remodeling of microglia morphology, both postnatally and at adulthood in different brain regions, that differently affect mood and cognition. The chronic blockade of adenosine A2A receptors (A2A R), which are core regulators of microglia morphology and physiology, ameliorated the cognitive deficits, but not the anxiety-like behavior. Notably, A2A R blockade rectified both microglia morphology in the dHIP and the lack of mPFC-dHIP synchronization, further heralding their role in cognitive function.

Cell transplantation using Mesenchymal stem cell (MSC) secretome have recently been presented as a possible free-based therapy for CNS related disorders. MSC secretome is rich in several bio-factors that act synergically towards the repair of damaged tissues, thus making it an ideal candidate for regenerative applications. Great effort is currently being made to map the molecules that compose the MSC secretome. Previous proteomic characterization of the secretome (in the form of conditioned media - CM) of MSCs derived from adipose tissue (ASC), bone-marrow (BMSC) and umbilical cord (HUCPVC) was performed by our group, where proteins relevant for neuroprotection, neurogenic, neurodifferentiation, axon guidance and growth functions were identified. Moreover, we have found significant differences among the expression of several molecules, which may indicate that their therapeutic outcome might be distinct. Having this in mind, in the present study, the neuroregulatory potential of ASC, BMSC and HUCPVC CM in promoting neurodifferentiation and axonal outgrowth was tested in vitro, using human telencephalon neuroprogenitor cells and dorsal root ganglion explants, respectively. The CM from the three MSC populations induced neuronal differentiation from human neural progenitor cells, as well as neurite outgrowth from dorsal root ganglion explants. Moreover, all the MSC populations promoted the same extent of neurodifferentiation, while ASC CM demonstrated higher potential in promoting axonal growth.

Objetivos: identificar a oferta de alimentos complementares às crianças com idade inferior a dois anos, e sua conformidade com o Ministério da Saúde. Método: estudo realizado com 52 crianças em uma Unidade Básica de Saúde do Nordeste brasileiro, entre dezembro/2015 e fevereiro/2016. Realizou-se entrevistas com as mães aplicando-se um questionário socioeconômico e relacionado ao perfil alimentar infantil. Analisou-se os dados no programa estatístico R®. Classificou-se os alimentos consumidos em "não adequado" e "adequado" segundo o Ministério da Saúde. Resultados: dos maiores de 1 ano, uma (3,3%) estava em aleitamento complementar, já os menores de 1 ano (n=22/100%) faziam uso de mingau e 20 (90,9%) haviam consumido refrigerantes. Refrigerante, mingau, salgadinhos e biscoitos foram os alimentos mais consumidos. A alimentação "inadequada" prevaleceu nos menores de 1 ano. Conclusão: a alimentação é em sua maioria de produtos industrializados, tornando-se um problema de insegurança alimentar para a população do estudo (AU).
Objectives: To identify the offering of complementary foods to children aged below two years old, and the conformity of this with the Ministry of Health's recommendations. Method: a study undertaken with 52 children in a Primary Healthcare Center in the North East of Brazil, between December 2015 and February 2016. Interviews were held with the mothers, who were given a socioeconomic questionnaire which was also related to the children's dietary profile. The data were analyzed using the statistical program R®. The foods consumed were classified as either "not appropriate" or "appropriate", according to the Ministry of Health. Results: of the children older than one year, one (3.3%) was receiving complementary breastfeeding, while those younger than one year old (n=22/100%) were eating baby porridge ('mingau') 1 and 20 (90.9%) had already drunk soda. Soda, mingau, salted snacks and cookies were the foods consumed most. "Inappropriate" food was prevalent in the children younger than one year old. Conclusion: most of the food given consisted of industrialized products, and is thus a problem of food insecurity for the study population (AU).

In the advanced stages of illness, patients often face challenging decisions regarding their treatment and overall medical care. Terminal ill patients are commonly affected by infections. However, in palliative care, the use of antimicrobials can be an ethical dilemma. Deciding whether to treat, withhold, or withdraw the antimicrobial treatment for an infection can be difficult. Antimicrobial administration can lead to adverse outcomes but the two main benefits, longer survival and symptom relief, are the main reasons why physicians prescribe antimicrobial when treating terminally ill patients. For the patient who has an irreversible advanced heart or lung disease, or an advanced dementia, or a metastatic cancer, it is easier the decision of withholding mechanical ventilation, tube feeding, and dialysis than antibiotherapy. To characterize infections, agents, and their treatments in palliative care, we conducted a review of the literature. We also included some tips to help health professionals to guide their clinical approach.
