Abstract
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of what influences variability, however, is limited by sparse data. We collected standardized surveys of herbivory for 503 plant species at 790 sites across 116° of latitude. With these data, we show that within-population variability in herbivory increases with latitude, decreases with plant size, and is phylogenetically structured. Differences in the magnitude of variability are thus central to how plant-herbivore biology varies across macroscale gradients. We argue that increased focus on interaction variability will advance understanding of patterns of life on Earth.

Abstract
Introduction Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms including inattention, hyperactivity and/or impulsivity that commonly persists into adulthood. Suicide is a major cause of death in adult ADHD (aADHD) patients. Suicidality is higher in these patients, in possible relationship to various clinical and socio-demographic factors. Objectives To review the current literature concerning potential risk factors for suicide in aADHD patients. Methods A research was made using the Medline database through the Pubmed search engine, with the following keywords: “adhd”, “suicide”, “risk factors”. Results Comorbid psychiatric disorders (major depressive disorder, sleep disturbances, behavior disorders and addictive disorders) are powerful predictors of suicidal behavior in aADHD. Depression is the most frequent diagnosis among aADHD patients with previous suicide attempts. Subtype (mostly the combined type) and severity of ADHD were also associated with a higher number of prior suicide attempts. Impulsiveness, poor emotional self-regulation, recklessness, persistent hyperactivity, inability to relax, engagement in risk behavior (often found in ADHD), common personality traits in aADHD like low frustration tolerance, maladaptive coping and poor problem-solving, as well as interpersonal relationship problems, were associated with higher suicidality. Financial distress caused by unemployment is associated with higher suicidal behaviors. The suicidality is higher in females, mostly associated to self-concept, whereas in males is typically related to impulsivity. Conclusions Clinicians should be aware of the potential risk factors for suicide in aADHD patients because the early detection of these factors is fundamental to improve the patients’ quality of life and could contribute to the design of more effective treatments.

Abstract
Introduction Esketamine is an S-enantiomer of ketamine approved by the EMA for treatment-resistant depression (TRD). As an NMDA receptor antagonist, its administration results in increase of glutamate release and AMPA receptor activation, supporting both rapid-onset and long-term antidepressant effects. Short-term tolerability seems acceptable but major concerns remain regarding long-term safety, specifically regarding potential neurocognitive toxicity. Objectives To clarify the potential short and long-term cognitive beneficial-effects and side-effects of esketamine. Methods Research was made using the Medline database, through the Pubmed search engine, using the keywords: “esketamine”, “cognition”. Only randomized-controlled trials were considered. Results One study focused on the effects of intranasal esketamine (INE) on cognitive functioning in 24 healthy individuals, who were evaluated pre- and postdose (40 min, 2h, 4h and 6h). The results showed a decline in cognitive performance at 40 min postdose, returning to comparable levels as placebo by 2h postdose. Another study, with a follow-up of 1 year, involving 802 TRD patients, accessed the long-term safety of INE. In patients aged <65 years-old, performance on all cognitive tests remained stable or slightly improved from baseline during long-term treatment. In patients ≥ 65 years-old, the mean performance on all tests improved or remained stable, while the simple and choice reaction time began slowing at week 20. Conclusions Esketamine has proven to be a promising new option for the treatment of TRD and available studies have shown promising results regarding patients’ cognitive function. Larger clinical trials are needed to further evaluate its short-term and long-term cognitive effects. Disclosure No significant relationships.

Abstract
Introduction Attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) are neurodevelopmental disorders that commonly persist into adulthood. ADHD in adults can resemble, and often co-occurs with, bipolar disorder (BD), which might lead to diagnostic errors, ineffective treatment and potentially serious adverse consequences. Objectives To review on the overlaps and differences in the psychopathology of the two entities and particularities of the management when they occur comorbidely. Methods The Medline database through the Pubmed search engine was used with the following keywords: “adhd” and “bipolar disorder”. Results ADHD has an estimated prevalence of 10-30% in adults with BD. Despite the symptomatic similarities, there are some important differences. In the ADHD/BD comorbidity, symptoms like attention-deficit, distractibility, irritability, impulsiveness and hyperactivity that may present in (hypo)manic and/or depressive episodes, tend to persist after clinical stabilization. While adult patients with ADHD typically experience ceaseless mental activity and wandering mind, BD patients may have racing thoughts and perceive them as making sense. ADHD patients may have poor socio-occupational achievement that may lead to low self-esteem, low self-confidence and depressed mood. Features like course of illness, psychiatric family history and treatment response may help differentiate the two entities. The treatment must start with mood stabilization and then proceed to the treatment of ADHD symptoms. Conclusions A complete clinical history, with particular focus in the neurodevelopmental history, is important but sometimes is not enough for an accurate diagnosis of this comorbidity. As so, clinicians should be aware of the high comorbidity rates to prevent misdiagnosis and provide the best care for both disorders. Disclosure No significant relationships.

Abstract
Intervertebral disc (IVD) degeneration and the consequent low-back pain (LBP) affect over 80 % of people in western societies, constituting a tremendous socio-economic burden worldwide and largely impairing patients' life quality. Extracellular matrix (ECM)-based scaffolds, derived from decellularised tissues, are being increasingly explored in regenerative medicine for tissue repair. Decellularisation plays an essential role for host cells and antigen removal, while maintaining native microenvironmental signals, including ECM structure, composition and mechanical properties, which are essential for driving tissue regeneration. With the lack of clinical solutions for IVD repair/regeneration, implantation of decellularised IVD tissues has been explored to halt and/or revert the degenerative cascade and the associated LBP symptoms. Over the last few years, several researchers have focused on the optimisation of IVD decellularisation methods, combining physical, chemical and enzymatic treatments, in order to successfully develop a cell-free matrix. Recellularisation of IVD-based scaffolds with different cell types has been attempted and numerous methods have been explored to address proper IVD regeneration. Herein, the advances in IVD decellularisation methods, sterilisation procedures, repopulation and biocompatibility tests are reviewed. Additionally, the importance of the donor profile for therapeutic success is also addressed. Finally, the perspectives and major hurdles for clinical use of the decellularised ECM-based biomaterials for IVD are discussed. The studies reviewed support the notion that tissue-engineering-based strategies resorting to decellularised IVD may represent a major advancement in the treatment of disc degeneration and consequent LBP.

Abstract
Glioblastoma (GB) is the most aggressive and common form of primary brain tumor characterized by fast proliferation, high invasion, and resistance to current standard treatment. The average survival rate post-diagnosis is 14.6 months, despite the aggressive standard post-surgery radiotherapy concomitant with chemotherapy with temozolomide (TMZ). Currently, efforts are being endowed to develop new and more efficient therapeutic approaches capable to overcome chemoresistance, inhibit tumor progression and improve overall patient survival rate. Abnormal microRNA (miRNA) expression has been correlated with chemoresistance, proliferation and resistance to apoptosis, which result from their master regulatory role of gene expression. Altered cell metabolism, favoring glycolysis, was identified as an emerging cancer hallmark and has been described in GB, thus offering a new target for innovative GB therapies. In this work, we hypothesized that a gene therapy-based strategy consisting of the overexpression of a miRNA downregulated in GB and predicted to target crucial metabolic enzymes might promote a shift of GB cell metabolism, decreasing the glycolytic dependence of tumor cells and contributing to their sensitization to chemotherapy with TMZ. The increase of miR-200c levels in DBTRG cells resulted in downregulation of mRNA of enzymes involved in bioenergetics pathways and impaired cell metabolism and mobility. Additionally, miR-200c overexpression prior to DBTRG cell exposure to TMZ resulted in cell cycle arrest. Overall, our results show that miR-200c overexpression could offer a way to overcome chemoresistance developed by GB cells in response to current standard chemotherapy, providing an improvement to current GB standard treatment, with benefit for patient outcome.

Abstract
IntroductionClassic psychedelics have been administered in sacramental contexts since ancient times. They were of prominent interest within psychiatry and neuroscience in the 1950s to 1960s, but the association between classic psychedelics and the emerging counterculture put an end to their research. Modern research with classic psychedelics has reinitiated interest in the treatment of both cancer-related distress and addiction, with really promising results.ObjectivesWe aim to provide a review about history and new insights regarding research with psychedelics specially as treatment of addictive disorders.MethodsA framing analysis of articles, searched on Pubmed (articles between 2010-2020) with the key words: “ psychedelics”, “psilocybin”, “substance use disorder”, “addiction”.ResultsClassic psychedelics are 5HT2AR agonists such as LSD, mescaline, and psilocybin. They were shown to occasion mystical experiences, which are experiences reported throughout different cultures and religions involving a strong sense of unity. These experiences are scientifically important because they appear to cause abrupt and sustained changes in behavior and perception, that can be very useful in the substance use disorder field. From this analysis is possible to understand that the use of psychadelics in the treatment of some addictions is currently at an early stage of research. However, they show interesting results with no clinically significant adverse events when risk individuals are excluded.ConclusionsIn comparison to psychedelic research about cancer-related psychological distress, studies with addictions are less developed, but if they continue to suggest safety and efficacy, may be the use of psilocybin for the treatment of specific addiction can happen in a close future.

Abstract
BACKGROUND Meningiomas are the most common primary brain tumors and are generally considered benign. However, a rare subgroup of meningiomas, classified as World Health Organization (WHO) grade III meningiomas, can show extremely aggressive behavior and high rates of recurrence. Despite ongoing research, data on the clinical outcome of this subgroup of meningiomas are still limited. METHODS Medical records of patients with WHO grade III meningiomas diagnosed between 2000 and 2018 at the Coimbra University Hospital Center were retrospectively reviewed and several variables of interest and their relation to patients' survival were analyzed. RESULTS Of the 26 patients included in the final analysis, 23 had anaplastic meningiomas, 2 had papillary meningiomas, and 1 had a rhabdoid meningioma. Median overall survival and median progression-free survival were 2.45 and 1.22 years, respectively. Overall survival at 1, 2 and 5 years was 73%, 57%, and 35%, respectively. Adjuvant radiotherapy correlated with improved survival for subtotally resected meningiomas but not for gross totally resected meningiomas. There was a trend toward improved overall survival with gross total resection versus subtotal resection, but this difference failed to reach statistical significance. CONCLUSIONS This study provides insight into the clinical outcomes of WHO grade III meningiomas and suggests that adjuvant radiotherapy may not be beneficial for patients who underwent gross total resection. This rare subset of meningiomas still portends a devastating prognosis and the impact of extent of resection and adjuvant therapies in these patients needs further clarification.

Abstract
Glioblastoma (GB) is the most frequent and malignant type of brain tumor, for which no effective therapy exists. The high proliferative and invasive nature of GB, as well as its acquired resistance to chemotherapy, makes this type of cancer extremely lethal shortly after diagnosis. Long non-protein coding RNAs (lncRNA) are a class of regulatory RNAs whose levels can be dysregulated in the context of diseases, unbalancing several physiological processes. The lncRNA associated with microvascular invasion in hepatocellular carcinoma (lncRNA-MVIH), overexpressed in several cancers, was described to co-precipitate with phosphoglycerate kinase 1 (PGK1), preventing secretion of this enzyme to the extracellular environment and promoting cell migration and invasion. We hypothesized that, by silencing the expression of lncRNA-MVIH, the secretion of PGK1 would increase, reducing GB cell migration and invasion capabilities. We observed that lncRNA-MVIH silencing in human GB cells significantly decreased glycolysis, cell growth, migration, and invasion and sensitized GB cells to cediranib. However, no increase in extracellular PGK1 was observed as a consequence of lncRNA-MVIH silencing, and therefore, we investigated the possibility of a mechanism of miRNA sponge of lncRNA-MVIH being in place. We found that the levels of miR-302a loaded onto RISC increased in GB cells after lncRNA-MVIH silencing, with the consequent downregulation of several miR-302a molecular targets. Our findings suggest a new mechanism of action of lncRNA-MVIH as a sponge of miR-302a. We suggest that lncRNA-MVIH knockdown may be a promising strategy to address GB invasiveness and chemoresistance, holding potential towards its future application in a clinical context.

Abstract
Acoustic data was collected across 15 sites distributed through the coastal area of Rio de Janeiro, Brazil, encompassing regions of different natural characteristics. Noise levels and the acoustic complexity index were calculated. Quantity and composition of anthropogenic sound sources varied across recording sites, with at least one type of sound source being registered in each location. A cluster analysis using third-octave levels from eight frequency bands divided recording sites into two groups, one considered as impacted by anthropogenic noise and the other as less-impacted. The noisiest recording locations were those with higher numbers of anthropogenic sound sources, specifically large ships. It was evidenced that anthropogenic noise affects not only noise levels, but also low-frequency acoustic complexity, which decreased in the presence of vessel traffic. The constant noise input of human activities tended to mask natural variability in the soundscape at lower frequencies.

Abstract
The regulatory structures can become determinants in the organizational process of health management, as it has the possibility of giving more effective responses to the user who seeks the Brazilian health system. The objective of the study is to analyze the regulation of health services in Brazilian municipalities, considering the regulation centers, recommended by the legislation of the Unified Health System (SUS). This is a descriptive exploratory study with a qualitative focus, developed in municipal regulatory centers in Brazilian states, through semi-structured interviews. The sample consisted of eighteen managers and seventy regulation professionals, from September / 2017 to January 2018. As limiting factors in regulation, the following stand out: great demand for people; unavailability of beds; systemic difficulties in relation to the agreed services; procedures that are difficult to schedule and execute; problems in information flows between primary care and regulation. The main potentialities are: increased financial resources for health; reorganization of internal regulatory procedures; meeting users' needs; health training for regulatory professionals; and strengthening primary health care. The study showed that it is difficult to concentrate higher education professionals to perform the tasks of regulators of medium and high complexity procedures; there are obstacles to operationalize the regulatory process, since the regulatory structures created coexist with insufficient resources, agreements that are inconsistent with the country's reality; there is recognition of the need for a strong regulatory component in guaranteeing qualified access to health, and one of the greatest challenges is to understand the multiplicity of scenarios, subjects and interests, and to implement user-centered strategies.

Abstract
BACKGROUND Solitary spinal amyloidoma (SSA) is a rare and poorly characterized disease. There are few cases described, and the knowledge of this neoplasm is limited. A more accurate description of demographics, clinical findings, and outcomes may be useful for a better understanding of this pathology, as well as therapeutic intervention, adding value to the research of localized amyloidosis. METHODS A systematic search was carried out from when registries began until February 2020. We also include a case diagnosed and treated in our department. Descriptive statistics were used to evaluate data, demographics, clinical findings, diagnostic modalities, therapeutics, and finally neurologic outcomes. The Kaplan-Meier method was used to assess overall survival and progression-free survival. RESULTS The final cohort comprises 35 patients. The mean age at diagnosis was 61.97 years, and 68.60% of the patients were male. SSA developed more frequently in the thoracic spine (48.60%), followed by the cervical spine (17.10%). Intradural lesions were rare, and the average neoplastic score for spinal instability was 9.5 points. The most common symptoms were impaired motor function (74.29%) and axial back pain (65.70%). After surgery, neurologic recovery was reported in 82.90% of cases. Mean progression-free survival and mean overall survival were 47.26 and 156.66 months. CONCLUSIONS SSA is a rare subgroup of localized amyloidosis, usually being diagnosed in male patients between the sixth and eighth decades. The gold standard treatment seems to be surgical resection. SSA patients have excellent long-term survival and a low rate of local recurrence.

Abstract
Glioblastoma (GB) is the most aggressive and common form of primary brain tumor, characterized by fast proliferation, high invasion, and resistance to current standard treatment. The average survival rate post-diagnosis is only of 14.6 months, despite the aggressive standard post-surgery treatment approaches of radiotherapy concomitant with chemotherapy with temozolomide. Altered cell metabolism has been identified as an emerging cancer hallmark, including in GB, thus offering a new target for cancer therapies. On the other hand, abnormal expression levels of miRNAs, key regulators of multiple molecular pathways, have been correlated with pathological manifestations of cancer, such as chemoresistance, proliferation, and resistance to apoptosis. In this work, we hypothesized that gene therapy based on modulation of a miRNA with aberrant expression in GB and predicted to target crucial metabolic enzymes might impair tumor cell metabolism. We found that the increase of miR-144 levels, shown to be downregulated in U87 and DBTRG human GB cell lines, as well as in GB tumor samples, promoted the downregulation of mRNA of enzymes involved in bioenergetic pathways, with consequent alterations in cell metabolism, impairment of migratory capacity, and sensitization of DBTRG cells to a chemotherapeutic drug, the dichloroacetate (DCA). Taken together, our findings provide evidence that the miR-144 plus DCA combined therapy holds promise to overcome GB-acquired chemoresistance, therefore deserving to be explored toward its potential application as a complementary therapeutic approach to the current treatment options for this type of brain tumor.

Abstract
AIM Secondary sphincter repair has been the conventional management of anal incontinence (AI) when a structural defect in the sphincter is recognized. However, disappointing long-term results have contributed to a tendency towards an increasing use of alternative treatment methods. This study aimed to assess the long-term functional outcomes following a secondary sphincter repair in women with AI after obstetric sphincter injury. METHOD This is a questionnaire study of women who underwent a secondary sphincter repair in Denmark between January 1990 and December 2005. Patients were identified through the Danish National Patient Registry. Functional outcomes were assessed by a self-administered questionnaire in 2010 and 2018. Primary outcomes were Wexner and St. Mark's scores. Impact on quality of life was assessed using the Fecal Incontinence Quality of Life Scale. RESULTS Functional outcome was assessed in 370 women in 2010 and 255 women in 2018. At 18.3 [interquartile range (IQR 15.0-22.0)] years of follow-up, the mean ± SD Wexner score was 8.8 ± 4.8 and the mean St. Mark's score was 11.7 ± 5.0. Flatus incontinence was the most frequent symptom, reported by 97%. Incontinence for liquid and solid stools was reported by 75% and 54%, respectively. There were no significant changes in incontinence frequencies over time. Women with a Wexner score of ≥ 9 had a significantly lower quality of life score in all domains than did women with a Wexner score of < 9 (P < 0.001). CONCLUSION At long-term follow-up, few patients are fully continent following a secondary sphincter repair. However, it appears that the functional results remain stable at very long-term follow-up.

Abstract
Abstract
Sinus of Valsalva aneurysms are a rare pathology that can be clinically silent during years and/or become suddenly symptomatic. We described 3 cases with different clinical presentation, complications and surgical treatment.
A 26-year-old male, competitive cyclist was admitted with a 1.5 month history of fatigue, palpitations, and nocturnal cough and sweating. At physical examination he was apyretic, blood pressure 157/49mmHg and radial pulse 96 bpm; jugular vein engorgement and continuous heart murmur, were noticed. Blood samples only revealed a mild raised BNP. EKG showed sinus tachycardia and right intraventricular conduction delay and the transthoracic echocardiography (TTE) revealed high velocity systolic-diastolic shunt (image) between a non-dilated right coronary sinus (RCS) and the right atrium (RA); moderate left ventricle dilation, severe right atrium and mild right ventricle enlargement with mild pulmonary hypertension and normal biventricular systolic function. He was referred to angioCT that showed a large communication between a non-dilated RCS and RA with signs of right ventricular overload. He was submitted to surgery, where ruptured aneurysm sac was found. Fistula closure, aneurysm sac suture and tricuspid annuloplasty were performed.
A 45-year-old male asymptomatic, with no relevant medical background went to a Cardiology consultation after detection of a holossistolic murmur in the physical exam. EKG showed sinus rhythm arrhythmia with a nonspecific intraventricular conduction delay and the TTE revealed a communication between a dilated noncoronary sinus (NCS) and RA; the biventricular systolic function was normal. He was referred to angioCT which confirmed the diagnosis. He was submitted to surgery where an exeresis and closure of the fistula was performed.
A 38-year-old male with no relevant medical background was admitted to emergence room for an intermittent anterior thoracic pain radiating to the neck (2 days of evolution). The EKG showed sinus tachycardia, incomplete right bundle branch block and the high-sensitivity troponin assays were negative. The TTE revealed severe sinus of Valsalva aneurysm, particularly of the NCS with mild aortic regurgitation. The patient performed transesophageal echocardiography and angioCT which excluded an acute aortic syndrome. He was oriented to surgery where a contained rupture of the RCS and a non-visualization of the ostium right coronary artery were detected, suggesting an intimal dissection. The patient was submitted to Bentall procedure and a bypass with internal mammary artery to right coronary artery.
In spite of the unclear etiology, all the cases had a good clinical and echocardiographic evolution at follow-up. The difficulty in making a timely diagnosis is related to the variability of clinical presentation and the need of high clinical suspicion. Echocardiography and angioTC have demonstrated its value, in providing a prompt diagnosis and appropriate management guidance.

Abstract
One of the major challenges in Glioblastoma (GBM) therapy relates with the existence of glioma stem-like cells (GSCs), known to be chemo- and radio-resistant. GSCs and non-stem GBM cells have the ability to interchange, emphasizing the importance of identifying common molecular targets among those cell sub-populations. Nucleolin overexpression has been recently associated with breast cancer sub-populations with different stem-like phenotype. The goal of this work was to evaluate the potential of cell surface nucleolin as a target in GBM cells. Different levels of nucleolin expression resulted in a 3.4-fold higher association of liposomes targeting nucleolin (functionalized with the nucleolin-binding F3 peptide) in U87, relative to GBM11 glioblastoma cells. Moreover, nucleolin was suggested as a potential marker in OCT4-, NANOG-positive GSC, and in the corresponding non-stem GBM cells, as well as in SOX2-positive GSC. Doxorubicin delivered by liposomes targeting nucleolin enabled a level of cytotoxicity that was 2.5- or 4.6-fold higher compared to the non-targeted counterparts. Importantly, an overexpression of nucleolin was also observed in cells of patient-derived samples, as compared with normal brain. Overall, these results suggested nucleolin as a therapeutic target in GBM.

Abstract
Several classification systems have been proposed to address genomic heterogeneity of glioblastoma multiforme, but they either showed limited prognostic value and/or are difficult to implement in routine diagnostics. Here we propose a prognostic stratification model for these primary tumors based on tumor gene amplification profiles, that might be easily implemented in routine diagnostics, and potentially improve the patients management. Gene amplification profiles were prospectively evaluated in 80 primary glioblastoma multiforme tumors using single-nucleotide polymorphism arrays and the results obtained validated in publicly available data from 267/347 cases. Gene amplification was detected in 45% of patients, and chromosome 7p11.2 including the EGFR gene, was the most frequently amplified chromosomal region – either alone (18%) or in combination with amplification of DNA sequences in other chromosomal regions (10% of cases). Other frequently amplified DNA sequences included regions in chromosomes 12q(10%), 4q12(7%) and 1q32.1(4%). Based on their gene amplification profiles, glioblastomas were subdivided into: i) tumors with no gene amplification (55%); ii) tumors with chromosome 7p/EGFR gene amplification (with or without amplification of other chromosomal regions) (38%); and iii) glioblastoma multiforme with a single (11%) or multiple (6%) amplified DNA sequences in chromosomal regions other than chromosome 7p. From the prognostic point of view, these amplification profiles showed a significant impact on overall survival of glioblastoma multiforme patients (p>0.001). Based on these gene amplification profiles, a risk-stratification scoring system was built for prognostic stratification of glioblastoma which might be easily implemented in routine diagnostics, and potentially contribute to improved patient management.

Abstract
OBJECTIVE In utero fetal surgery to correct incomplete closure of the spinal cord lessens the extent of permanent damage but is associated with preterm prelabour rupture of membranes (PPROM). We determined whether compounds in amniotic fluid collected at the time of surgery predicted subsequent development of PPROM. DESIGN Prospective study. SETTING Hospitals in Sao Paulo, Brazil. POPULATION Twenty-four consecutive pregnant women at 24-26 weeks of gestation seen between February and October 2017 with a singleton pregnancy underwent in utero surgery to correct an open spinal defect in their fetus. METHODS Amniotic fluid was tested for lactic acid, matrix metalloproteinase 2 (MMP-2), MMP-8, MMP-9 and interleukin-6 (IL-6) by enzyme-linked immunosorbent assay. Clinical data were collected after completion of all laboratory studies. MAIN OUTCOME MEASURE Amniotic fluid concentration of compounds in women with or without PPROM. RESULTS Preterm prelabour rupture of membranes occurred in seven (29.2%) women. There were no differences in maternal age, gravidity, parity, race, history of caesarean sections or fetal gender between women with or without PPROM. Length of surgery, days of wound healing and length of hospital stay were also indistinguishable. The median concentrations of MMP-8 (1.7 versus 0.6 ng/ml; P = 0.0041) and lactic acid (7.1 versus 5.9 mm; P = 0.0181) were higher in women with PPROM. The amniotic fluid MMP-8 level was also negatively correlated with gestational age at delivery (Spearman r = -0.4217, P = 0.0319). CONCLUSION Differences in susceptibility to develop PPROM are present before fetal surgery. An increase in anaerobic glycolysis, evidenced by the intra-amniotic lactic acid level, may enhance MMP-8 production and weaken maternal and fetal membranes. TWEETABLE ABSTRACT Matrix metalloproteinase-8 and lactic acid in amniotic fluid predict preterm prelabour rupture of membranes.

Abstract
OBJECTIVES To analyze the muscle architecture and the expression pattern of the myosin heavy chain (MyHC) isoforms in the supraspinatus of Pan troglodytes and Homo sapiens in order to identify differences related to their different types of locomotion. MATERIALS AND METHODS We have analyzed nine supraspinatus muscles of Pan troglodytes and ten of Homo sapiens. For each sample, we have recorded the muscle fascicle length (MFL), the pennation angle, and the physiological cross-sectional area (PCSA). In the same samples, by real-time quantitative polymerase chain reaction, we have assessed the percentages of expression of the MyHC-I, MyHC-IIa, and MyHC-IIx isoforms. RESULTS The mean MFL of the supraspinatus was longer (p = 0.001) and the PCSA was lower (p < 0.001) in Homo sapiens than in Pan troglodytes. Although the percentage of expression of MyHC-IIa was lower in Homo sapiens than in Pan troglodytes (p = 0.035), the combination of MyHC-IIa and MyHC-IIx was expressed at a similar percentage in the two species. DISCUSSION The longer MFL in the human supraspinatus is associated with a faster contractile velocity, which reflects the primary function of the upper limbs in Homo sapiens-the precise manipulation of objects-an adaptation to bipedal locomotion. In contrast, the larger PCSA in Pan troglodytes is related to the important role of the supraspinatus in stabilizing the glenohumeral joint during the support phase of knuckle-walking. These functional differences of the supraspinatus in the two species are not reflected in differences in the expression of the MyHC isoforms.

Abstract
The ability to regulate our own physiological arousal when dealing with the emotional expression of our partner is crucial for satisfactory and stable intimate relationships. In previous physiological studies of marital interactions, researchers have found greater levels of psychophysiological arousal for members of the couple in conflictual interactions in comparison with positive interactions. Past researchers have established that intense and prolonged autonomic and neuroendocrine arousal during marital conflict can have negative consequences for mental and physical health. In this study we examined the physiological reactivity, as measured by skin conductance level, heart rate and cortisol levels, from both partners during a couple's interaction task consisting of a structured conversation about positive and negative aspects of their relationship. Participants were thirty-two heterosexual couples (N = 64) in a committed monogamous relationship with a minimum duration of one year. We found higher heart rate and cortisol levels during negative interaction condition when compared with the positive condition. Skin conductance was higher in the positive interaction condition, when compared with the negative interaction condition. In addition, we found a significant negative association between heart rate variability and autonomic arousal evoked by the interaction task. The implications of these findings for the effects of marital strain on health as well as for the design of risk-reducing interventions, namely biofeedback are discussed.

Abstract
Glioblastoma (GBM) is the most malignant primary brain tumor, with an average survival rate of 15 months. GBM is highly refractory to therapy, and such unresponsiveness is due, primarily, but not exclusively, to the glioma stem-like cells (GSCs). This subpopulation express stem-like cell markers and is responsible for the heterogeneity of GBM, generating multiple differentiated cell phenotypes. However, how GBMs maintain the balance between stem and non-stem populations is still poorly understood. We investigated the GBM ability to interconvert between stem and non-stem states through the evaluation of the expression of specific stem cell markers as well as cell communication proteins. We evaluated the molecular and phenotypic characteristics of GSCs derived from differentiated GBM cell lines by comparing their stem-like cell properties and expression of connexins. We showed that non-GSCs as well as GSCs can undergo successive cycles of gain and loss of stem properties, demonstrating a bidirectional cellular plasticity model that is accompanied by changes on connexins expression. Our findings indicate that the interconversion between non-GSCs and GSCs can be modulated by extracellular factors culminating on differential expression of stem-like cell markers and cell-cell communication proteins. Ultimately, we observed that stem markers are mostly expressed on GBMs rather than on low-grade astrocytomas, suggesting that the presence of GSCs is a feature of high-grade gliomas. Together, our data demonstrate the utmost importance of the understanding of stem cell plasticity properties in a way to a step closer to new strategic approaches to potentially eliminate GSCs and, hopefully, prevent tumor recurrence.

Abstract
OBJECTIVE To evaluate facial morphology of non-mixed indigenous people living in the Xingu region. Studies on these populations report that the total genetic diversity is as high as that observed for other continental populations. On the other hand, eating habits are different between indigenous and urban population, as indigenous people still have traditional habits. SETTING AND SAMPLE POPULATION The sample consisted of 106 indigenous subjects, in permanent dentition stage, belonging to four groups: Arara-Laranjal (n = 35), Arara-Iriri (n = 20), Xikrin-Kaiapó (n = 24), and Assurini (n = 27). MATERIAL AND METHODS Standardized facial photographs were obtained, and fourteen measurements were analyzed. Intra- and intergroup homogeneities were examined by discriminant analysis, followed by anova and Kruskal-Wallis tests. Sexual dimorphism to each village was analyzed by Student's t-test or Mann-Whitney test, at p < 0.05. RESULTS Significant facial differences were found between male and female, indicating that sex data should not be grouped for intergroup comparison. Discriminant analysis showed a large intergroup heterogeneity, while an intragroup homogeneity was found, especially for females. It was also observed that some morphological features of the face are specific to some villages, regardless of ethnicity. CONCLUSIONS Facial morphological characteristics were strongly different among groups, even comparing villages from the same ethnicity. Furthermore, a low diversity within groups was observed. Our findings, supported by previous reports on genetics and eating habits in these populations, reinforce the role of the genetic determination on craniofacial morphology.

Abstract
The increase in prevalence of Autism Spectrum Disorders (ASD) demands that new strategies for delivering speech-language therapy services to them are tested and improved. Including families and familiar situations may be a way to provide more intensive stimulation. The aim of this study was to identify strategies to stimulate communication development of children with ASD that can be suggested to parents and followed-up systematically. Participants were 67 children with diagnosis within the autism spectrum that attended weekly speech-language therapy at a specialized service of a large university in São Paulo (Brazil). The study was conducted in four phases: planning of activities; four face-to-face meetings with the parents to suggest and discuss activities that should be conducted at home daily; during six weeks the parents continued to conduct the proposed activities at home, with systematic weekly follow-up by the child's therapist finally, individual the parents reported their impressions about the proposal and the outcomes regarding their child's development during individual interviews. Activities involved the main areas of disorders in ASD. They suggested that the parents used familiar situations as opportunities for games and plays involving language, cognitive and social demands. Parents reported difficulties in implementing the proposed routine of playing with their child for at least a few minutes every day. They mentioned “lack of time” and “being tired” as the main reasons for it. Nevertheless they all reported that they were more able to understand their child's needs and demands and that their child responded well to the suggestions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Fluctuating asymmetry (FA) is a parameter to measure developmental stability in plants, which can be altered by disturbances, pollution, and biotic factors such as herbivory. We evaluated the effects of environmental stress and herbivory on the FA levels in individuals of Tibouchina heteromalla (Melastomataceae) that occur in natural and undergoing restoration areas in rupestrian grasslands at Serra do Cipó, Brasil. Individuals were collected and measured in seven restored and five natural areas, totalizing 240 individuals. We found that individuals in restored areas had greater leaf area, higher levels of insect herbivory and FA compared to individuals that occurred in natural areas. In both environments, the proportion of individuals with leaf damage caused by herbivory was higher than the proportion of undamaged individuals. In addition, FA was positively correlated with herbivory and total leaf area in both restored and natural areas. These results suggest that more favorable conditions in the restored areas enhanced leaf growth, resulting in higher FA.
