Brazil – one of the world's largest biocultural diversities – faces high rates of habitat loss, social inequality, and land conflicts impacting indigenous and local peoples. To challenge that, Brazilian sustainability science and education needs to be strengthened. We searched for elements in ongoing bottom-up sustainability social movements that can help serve that purpose. We found values, contents, and attitudes that, if incorporated into Brazilian sustainability science and education, can assist its transformative potential by reflecting local voices and critically engaging with (often-hegemonic) northern concepts.
Technical summary
In Brazil, a strong sustainability science and education is required to confront ‘glocal’ issues such as zoonotic pandemics and climate change, which are worsened by rampant ecosystem loss and social vulnerability. However, a largely disciplinary university system has been slow to meet these urgent needs. To address if and how dialogical processes with non-academics can prompt integration between distinct types of knowledge, we analyze four bottom-up sustainability initiatives that promote dialogues between science, the arts, religion, youth, and indigenous and local knowledge, and reflect on lessons learnt with movement organizers, scientists, and educators – the authors of this paper. Although sustainability science produced in dialogue with other forms of knowledge is still emerging in Brazil, we find that bottom-up initiatives outside academia can inspire science and education to approach sustainability as wholeness – a state of balance to be fulfilled when reached individually, collectively, and cosmically. We discuss how to approach a transdisciplinary and reflexive attitude in Brazilian sustainability science and education, and highlight its unique contribution to frontier topics in global sustainability debates.
Social media summary
Social movements’ values, contents, and attitudes can inspire transformative Brazilian sustainability science and education.
Research synthesis, using techniques such as meta-analysis to combine the results of a number of studies, is a particularly useful technique when there are multiple studies with conflicting results, or where there may be conflicting interests, and can serve to extract the maximum information from animal experiments. The effect of conventional cages and alternative housing systems on measures of production, behaviour, physical and physiological condition in laying hens is an important question that would benefit from research synthesis. We found that statistical constraints did not allow the usual methods of meta-analysis, so as a first step towards quantitative comparison, we used a simple vote-counting approach based on the treatment means. We counted the number of papers in which conventional cages or alternative systems had a higher weighted mean for various response variables. Egg production was higher in conventional cages than in alternative systems, though this effect was probably mostly confined to the comparison with multi-level indoor systems. Bones were stronger from hens kept in alternative systems than those kept in conventional cages. We confirmed previous reviews that birds show more comfort behaviour and possibly dustbathing (or vacuum dustbathing) behaviour in alternative systems, but aggressive pecking did not differ between systems. Perhaps surprisingly, mortality, feather pecking and body wounds were not found to differ between systems. The latter findings suggest that the chance of a mortality or cannibalism outbreak may be no greater in alternative systems than in cage systems, but it should be noted that our analysis did not consider the magnitude of the difference in mortality. In conclusion, the meta-comparison undertaken here supports some but contradicts other conclusions reached in qualitative reviews.
A bibliometric analysis was undertaken to chart the development of animal welfare (AW) science as a whole, and of the individuals, organisations and countries that have had most academic impact to date. Publication data were collected from the Web of Science for the year range 1968-2017 and by-hand pre-processing of the data was undertaken to identify reviews and original research articles on AW. VOSviewer was used to create bibliometric networks. There has been a 13.3% annual growth in AW publications in the last 50 years with Animal Welfare and Applied Animal Behaviour Science the most frequent publishers of AW publications. Farm animals continue to dominate the subject of AW research and comparison of network visualisations for five key species suggested possible gaps in the research, such as relatively little emphasis on emotion research for some farm animals and little research on inherited disorders in dogs. However, keyword analysis indicated a recent broadening of AW findings to include other international contexts, such as conservation and sustainability. Highly cited review articles were grouped into five clusters with affective state (ie emotions, moods) and fish welfare the most recent topics. Almost all core authors of original research articles study farm animals, though in the last ten years other topics, such as consumer attitudes and wildlife, have emerged as highly cited areas of original research articles. Network analysis of organisations revealed the University of Bristol, UK as the main publisher of original research articles. Citation analysis indicated that many low-cited articles were originating from Germany and were published in German journals, suggesting that many worthwhile results and opinions on AW may be being missed by other researchers due to a language barrier. Several limitations of bibliometric analysis to generate an overview of AW science were identified, including the challenge of how to search and extract all the relevant publications in this discipline. In conclusion, animal welfare science is still in an exponential phase of growth which will bring opportunities, such as for the publication of new journals, but also challenges. The insights generated by this study suggest bibliometric analysis to be a useful addition to other approaches investigating the trends and concepts of animal welfare.
Herpes zoster virus can cause inflammatory neuropathy of the facial nerve. However, studies evaluating the prevalence of this agent in peripheral facial palsy are heterogeneous regarding sample group selection, laboratory analysis method and variables studied. In addition, there are a lack of epidemiological data in the Brazilian population on this serological phenomenon in peripheral facial palsy. This study estimated herpes zoster reactivation prevalence in serological samples through chemiluminescence immunoassay for quantitative determination of specific antibodies directed against the virus.
Methods
This cross-sectional study sought to determine the prevalence of viral reactivation by herpes zoster in subjects with idiopathic peripheral facial palsy through analysis of serological samples over a year.
Results
Forty-seven patients (32 females and 15 males) participated. Severe paralysis was more common in older patients (p = 0.017). Facial pain (p = 0.02) and vertigo (p = 0.001) were related to a worse evolution of facial palsy. The rate of serological reactivation of the virus was 12.76 per cent.
Conclusion
The rate of serological reactivation of herpes virus in idiopathic peripheral facial palsy in our population is similar to foreign literature data, suggesting similar aetiological mechanisms in the genesis of this morbidity.
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly commissioned 64-dish SARAO MeerKAT radio telescope in South Africa. MeerKAT is a high-gain (${\sim}2.8\,\mbox{K Jy}^{-1}$) low-system temperature (${\sim}18\,\mbox{K at }20\,\mbox{cm}$) radio array that currently operates at 580–1 670 MHz and can produce tied-array beams suitable for pulsar observations. This paper presents results from the MeerTime Large Survey Project and commissioning tests with PTUSE. Highlights include observations of the double pulsar $\mbox{J}0737{-}3039\mbox{A}$, pulse profiles from 34 millisecond pulsars (MSPs) from a single 2.5-h observation of the Globular cluster Terzan 5, the rotation measure of Ter5O, a 420-sigma giant pulse from the Large Magellanic Cloud pulsar PSR $\mbox{J}0540{-}6919$, and nulling identified in the slow pulsar PSR J0633–2015. One of the key design specifications for MeerKAT was absolute timing errors of less than 5 ns using their novel precise time system. Our timing of two bright MSPs confirm that MeerKAT delivers exceptional timing. PSR $\mbox{J}2241{-}5236$ exhibits a jitter limit of $<4\,\mbox{ns h}^{-1}$ whilst timing of PSR $\mbox{J}1909{-}3744$ over almost 11 months yields an rms residual of 66 ns with only 4 min integrations. Our results confirm that the MeerKAT is an exceptional pulsar telescope. The array can be split into four separate sub-arrays to time over 1 000 pulsars per day and the future deployment of S-band (1 750–3 500 MHz) receivers will further enhance its capabilities.
Spontaneous abortion is considered a public health problem having several causes, including infections. Among the infectious agents, bacteria of the vaginal microbiota and Ureaplasma parvum have been associated with abortion, but their participation needs to be further elucidated. This study aims to evaluate the influence of Mollicutes on the development of spontaneous abortion. Women who underwent spontaneous abortion and those with normal birth (control) were studied. Samples of cervical mucus (CM) and placental tissue were collected to identify Mollicutes using the quantitative polymerase chain reaction methodology. Eighty-nine women who had a miscarriage and 20 women with normal pregnancies were studied. The presence of Mollicutes in placental tissue increased the chance of developing miscarriage sevenfold. The prevalence of U. parvum in women who experienced spontaneous abortion was 66.3% in placental tissue. A positive association was observed between the detection of U. parvum in samples of placental tissue and abortion. There was a significant increase in microbial load in placental tissue for M. hominis, U. urealyticum and U. parvum compared to the control group. Detection of U. parvum in CM in pregnant women can ascend to the region of the placental tissue and trigger a spontaneous abortion.
The nosologies founded by Kraepelin (Psychotic Disorders) and Freud (Neurotic Disorders) still remain actual in categories F20-29, F30-39 and F40-49 of the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10). The psychopathological mechanisms observed in classic disorders are shared with disorders considered in other categories regarding recognized etiologies (F10-19), ages of onset (F90-98), symptoms as precocious and enduring traces (F60-69) or specific symptoms (F50-59). Each classic pathology and its psychopathological mechanisms may be prototypical for a specific nosological spectrum that includes diseases which seem different at first glance. Accordingly, based on the combined knowledge of psychopathology and neurosciences, we assume that it is possible to conceive a more logical, rational and simpler way of organizing psychiatric nosology based on different psychopathological mechanisms emerging from five major questions:
1.does the patient recognize his territory? (Dementia and delirium spectra),
2.does the patient accurately recognise himself and the other? (Schizophrenic vs. autistic spectra),
3.does the patient conserve his synchronicity with environmental and interpersonal rhythms? (Manic and depressive spectra),
4.how does the patient feel about and react to threatening experiences? (Phobic vs. paranoid spectra), and
5.how does the patient behave towards appetizing experiences? (Obsessive vs. Dissociative spectra).
We also discuss the relationship of these major questions with the encephalic stages (telencephalon, diencephalon, mesencephalon, and rhombencephalon).
There are several useful methods to induce anxiety in patients with panic disorder with agoraphobia (PDA). Our aim was to ascertain if a virtual reality simulation could induce anxiety and physiologic alterations in PDA patients.
Methods
10 healthy controls (HC) and 10 patients who fulfilled DSM-IV criteria for PDA were recruited for this study. Before and after the experiment the anxiety level was measured with the Subjective Units of Distress Scale (SUDS), the Diagnostic Symptom Questionnaire (DSQ) was used to ascertain panic attack symptoms. The heart rate, skin conductance and respiration parameters were monitored during the exposure to the VR. The virtual reality simulation was a 3D computer animation of a short bus trip, from a first person perspective. The Igroup Presence Questionnaire (IPQ) was used to measure the sense of presence.
Results
PDA patients had higher familial history of panic disorder. From the 10 PDA patients only 3 were not taking medications. In PDA patients the VR exposure increased anxiety levels, they also had higher scores in the DSQ and two of them had panic attacks. Compared to the HC, the PDA patients had higher skin conductance levels, electrodermal response magnitude, respiratory rate, tidal volume, and respiratory rate irregularities. The heart rates were higher for patients who had panic attacks, followed by the HC and the non-panicking patients. Regarding the sense of presence the two groups were similar.
Conclusion
This study indicated that VR exposure may induce anxiety, electrodermal and respiratory alterations in patients with PDA.
The imprecise status of Psychiatry may be due to Cartesian dualism and the mind / body assumption. We can clarify this status resorting to an alternative ontology. Popper's Worlds 1, 2 and 3, and the corresponding concepts of matter, energy and information, from Von Bertalanffy and his General Systems Theory, are candidates for a new ontology. Applying them to the history and present structure of Western Medicine, we can assume that General Surgery is the branch of medicine which deals with bodily matter, Internal Medicine deals with energy and Psychiatry is the branch which deals with information. The respective basic disciplines are Anatomy, Physiology and Psychology. None of them is a medical specialty, because specialties, such as Neurology, Urology and Cardiology, deal with a sub-system of the organism and may have a surgical, medical or even psychiatric emphasis. In the same way that the body / mind problem seemed important for Cartesian dualism, this triadic structure of Medicine may also inform a new ontology. The recent history of Philosophy may be interpreted as an attempt of looking for it.
Children with Gender Identity Disorder (GID) show a strong preference for sex-typed behaviors more characteristic of the opposite sex and a rejection or avoidance of sex-typed behaviors more characteristic of one's own sex. There are also signs of distress and discomfort about one's status as a boy or a girl, including verbal expressions of dislike or disgust about one's genital anatomy.
The behaviors that characterize GID in children occur in concert, not in isolation. It is this behavioral patterning that is of clinical significance, and recognition of the patterning is extremely important in conducting a diagnostic assessment. the authors describe the case of a 6-year-old boy with GID. the clinical referral occurred 3 years after the onset of the condition, at the age of 6, when his parents begin to feel that the pattern of behavior was no longer a “phase” and worried about the implications of his symptoms in his academic and social life.
This case illustrates some of the problems of the diagnosis, assessment, associated psychopathologies, developmental trajectories and therapeutic strategies for childhood GID, including parental considerations.
The case of a 72-year-old male patient with initial depressive symptoms and visual hallucinations, added to a progressive motor and cognitive neurological impairment, is presented. the patient died of pneumonia 7 weeks after the onset of the symptoms; the necropsy confirmed the diagnosis of Creutzfeldt-Jacob disease (CJD) suggested previously by complementary diagnostic tests (brain magnetic resonance imaging, electroencephalogram, 14-3-3 protein determination in the cerebrospinal fluid and study of the prionic protein gene).
Discussion:
CJD is a rare dementia characterized by a rapidly progressive course. Psychiatric symptoms, including depression and personality change, occur early in the clinical course in about a third of patients, being estimated in some studies that 10% of patients are first admitted to psychiatric wards. Psychiatric symptoms associated with CJD have often lead to erroneous initial diagnoses of functional psychosis, depressive pseudodementia, or hysteria.
Analysis of the psychiatric symptoms does not suggest specific features that rapidly allow the differentiation from more common psychiatric disorders, although the occurrence of associated persistent sensory symptoms may raise the possibility of this diagnosis. Later, the characteristic rapidly progressive neurological impairment is decisive in the affirmation of the diagnosis of CJD.
To describe therapeutic features of 120 panic disorder (PD) patients treated with clonazepam, paroxetine, or clonazepam + paroxetine for 3 years and their follow-up for more 6 years.
Method
A prospective open study randomized 120 PD patients to 2 mg/day clonazepam or 40 mg/day paroxetine. Poor responders were switched after 8 weeks to combined treatment with ∼2 mg/day clonazepam + ∼40 mg/day paroxetine. Tapered withdrawal of all treatments was performed after 3 years. Efficacy, safety, and cumulative relapse and remission were studied over the following 6 years, using panic attack (PA) count, clinical global impression-severity (CGI-S), and Hamilton anxiety scale (HAMA).
Results
94 patients completed 3 years treatment. All were free of panic attacks since at least one year before undergoing tapered drug withdrawal. After two months of tapering, 80% of clonazepam patients were drug-free, versus 55% on paroxetine. No serious or severe adverse event were observed but PA/month, CGI-S, and HAMA worsened slightly. In annually studied patients the relapse rates were similar after the 3 treatments with an advantage of clonazepam over the combination (p=0.0035) and paroxetine (p=0.08, exact Fisher) at the first year after drug withdrawal. Cumulative relapses rate were 41%, 77%, and 94% at years 1, 4, and 6, but relapse therapy with either clonazepam or paroxetine was successful in nearly all cases.
Conclusion
PD is a chronic disorder, with many patients relapsing after 3 years treatment. Response to retreatment was excellent. Paroxetine and clonazepam were associated with similar long-term prognoses but clonazepam was better tolerated.
Starting from atypical psychosis as a model of a psychotic entity typically associated with states of altered consciousness, and having as organic and physiological comparative models epileptic psychosis and dream, respectively, the authors seek to establish a fundamental condition for these phenomena. Then, assuming a phenomenological perspective, we analyze the latest neuroscientific findings in the field of psychosis, including schizophrenia, trying to extrapolate the findings obtained in atypical psychoses to all forms of psychosis, achieving a defining principle of psychosis. We conclude that psychosis consists in a disturbance of consciousness, namely, of a pre-reflective consciousness. This will be dependent on a complex neural system which, starting from a primordial feeling of Self, differentiates and branches out through higher brain structures along the ontogenetic development. A significant interference on the connectivity of this system leads to a commitment of effective intentionality in the psychotic individual, with a discontinuity in the search for meaning, and interaction of individuals in the world, where the regulation of primitive emotional tendencies for higher cognitive components is lost.
After the original description of the Ganser syndrome (GS), in 1898, there has been a great debate over the etiological primacy of either hysteria or psychosis (including organic states). Even now, despite the DSM-IV classification of GS as a dissociative disorder, this condition remains an extensively misunderstood condition. Not only has it been reported in association with various functional psychiatric disorders but also as organic states, most often in patients with head injury and stroke, especially those involving the frontal lobes.
A case of GS in a 47-year-old male patient admitted in the psychiatry ward due to a reactive depressive syndrome along with a personality disorder is presented. Throughout his stay in the inpatient unit, the patient developed a full blown GS after defenestration - in a paranoid context - with consequent head-trauma and internal hemorrhage in the fronto-temporal region of the dominant hemisphere.
The case illustrates some of the problems of nosology, clinical presentation, and psychopathology that this syndrome raises. The authors discuss the etiological dilemma and the complexities of the diagnosis of GS in the presence of an organic lesion accompanied by an overwhelming emotional component.
Narcolepsy is a disabling sleep disorder affecting 0.02% of adults worldwide. It is characterized by irresistible daytime sleepiness, catalepsy and can be associated with sleep paralysis, and hipnagogic hallucinations.
The treatment is essentially symptomatic with stimulant drugs (mostly dopaminergic) for daytime sleepiness and sleep attacks, antidepressants (mostly noradrenergic) for catalepsy and hypnotics for disturbed night-time sleep. Special care must be taken, with close blood monitoring for toxicity, in the prescription of these drugs to patients with concurrent renal or hepatic disease.
The authors present a case of a 72 year-old female patient with the diagnoses of narcolepsy and conjoint severe chronic renal and hepatic insufficiency, with intolerance for most of the recommended treatments for her sleep disorder. The patient is observed in a psychiatric consultation after several bone fractures due to cataleptic phenomena.
We describe a successful therapeutical approach with reboxetine, with a significant improvement in daytime sleepiness, reflected by a decrease of 52% on the Epworth Sleepiness Scale. Furthermore, a significant reduction in the cataplexy subscore of the Ullanlinna Narcolepsy Scale was also found. Consequently, this treatment led to a decrease in the frequency of catalepsy attacks and secondary traumatic injuries and an increase in the Global Assessment of Functioning scale.
to describe with prospective methodology the therapeutic response to clonazepam in the respiratory panic disorder (PD) subtype versus the non-respiratory subtype in a long-term follow-up.
Methods
A total of 67 PD outpatients (DSM-IV) were previously divided into respiratory (n = 35) and non-respiratory (n = 32) subtypes and then openly treated with clonazepam for 8 weeks. Those who responded were then treated for 3 years. Demographic and clinical features were compared in the two groups. The instruments used to evaluate response were the Clinical Global Impression, the Sheehan Panic and Anticipatory Anxiety Scale, and the Panic Disorder Severity Scale.
Results
In the first 8 weeks of treatment (acute phase), the respiratory subtype had a significantly faster response on all the major scales. During the follow-up and at the end of the study (week 156), there was no difference in the scale scores, and the reduction in panic attacks from baseline to end-point did not differ significantly between the two groups. After the acute phase treatment, the patients could undergo psychotherapy. In the respiratory subtype, the disorder had a later onset, was associated with a high familial history of anxiety disorder. The non-respiratory subtype had significantly more previous depressive episodes. Clonazepam had a safe adverse event profile during both phases of treatment.
Conclusion
The respiratory PD subtype had a faster response to treatment with clonazepam at 8 weeks than did the non-respiratory subtype and an equivalent response after 6 months of treatment. The response of clonazepam is clearly maintained during the long-term follow-up.

Multi-decade observing campaigns of the globular clusters 47 Tucanae and M15 have led to an outstanding number of discoveries. Here, we report on the latest results of the long-term observations of the pulsars in these two clusters. For most of the pulsars in 47 Tucanae we have measured, among other things, their higher-order spin period derivatives, which have in turn provided stringent constraints on the physical parameters of the cluster, such as its distance and gravitational potential. For M15, we have studied the relativistic spin precession effect in PSR B2127+11C. We have used full-Stokes observations to model the precession effect, and to constrain the system geometry. We find that the visible beam of the pulsar is swiftly moving away from our line of sight and may very soon become undetectable. On the other hand, we expect to see the opposite emission beam sometime between 2041 and 2053.
Even though mental disorders represent a major public health problem for women and respective children, there remains a lack of epidemiological longitudinal studies to assess the psychological status of women throughout pregnancy and later in life. This epidemiological cohort study assessed the relationship between mental disorders of 409 Brazilian women in pregnancy and 5–8 years after delivery.
Methods.
The women were followed from 1997 to 2000 at 17 health services, and subsequently from 2004 to 2006 at their homes. Mental disorders were investigated by the Perceived Stress Scale-PSS, General Health Questionnaire-GHQ and State-Trait Anxiety Inventories-STAI. The relationship between scores of the PSS, GHQ and STAI 5–8 years after delivery and in pregnancy was assessed by multivariate linear regression analysis, controlling for the following confounders: maternal age, education, per capita income, family size, work, marital status and body mass index.
Results.
Scores of the PSS, GHQ and STAI 5–8 years after delivery were positively associated with scores of the PSS, GHQ and STAI in the three trimesters of pregnancy, and inversely associated with maternal age and per capita income (adj. R2 varied from 0.15 to 0.37). PSS, GHQ and STAI scores in the 3rd trimester of pregnancy were positively associated with scores of the PSS, GHQ and STAI in the 1st and 2nd trimesters of pregnancy (adj. R2 varied from 0.31 to 0.65).
Conclusions.
The results of this study reinforce the urgency to integrate mental health screening into routine primary care for pregnant and postpartum women.
Many studies have assessed use of the outdoor ‘range’ area on free-range laying farms, and have revealed that percentage range use at any one time rarely exceeds 50% of the flock, and is sometimes below 10%. What constitutes a ‘good’ range use is difficult to determine without better knowledge of ranging bout lengths under ideal conditions. Well documented factors that affect percentage range use include prevailing weather, flock size and shelter on the range. Other factors such as pophole design, internal and external stocking density and system design appear to play a role although their effects are not as clear and more research would be valuable to truly understand their relevance. Factors affecting bird distribution on the range are also reviewed.
