Abstract
This study reports the development and validation of a new analytical method for simultaneous speciation analysis of Se and Hg in fish muscle. For this purpose, four Se species (selenite/Se(IV), selenate/Se(VI), selenomethionine/SeMet, and selenocysteine/SeCys) and two Hg species (inorganic mercury/iHg and methylmercury/MeHg) were extracted simultaneously by microwave-assisted enzymatic hydrolysis and then separated by HPLC in less than 15 min by using a column with both anion and cation exchange mechanisms and a mobile phase consisting of a mixture of methanol 5% (v/v), 45 mM HNO3, 0.015% 2-mercaptoethanol, and 1.5 mM sodium 3-mercapto-1-propanesulfonate. The separated species of Hg and Se were detected online by inductively coupled plasma-mass spectrometry (ICP-MS). The speciation analysis method was validated by means of the accuracy profile approach by carrying out three series of measurements in duplicate on three different days over a time-span of 3 weeks. The limits of quantification (LOQ) are in the range of 0.010-0.013 mg/kg wet weight (ww) for all selenium species, except for Se(IV) (0.15 mg/kg ww), while the coefficient of variation in terms of intermediate reproducibility (CVR) was < 7%. The LOQ for MeHg was 0.006 mg/kg ww, while the CVR was 3%. The method was successfully applied to the analysis of muscle samples from four different fish species: rainbow trout, tuna, swordfish, and dogfish.

Abstract
The role of tumor interaction with stromal components during carcinogenesis is crucial for the design of efficient cancer treatment approaches. It is widely admitted that tumor hypoxic stress is associated with tumor aggressiveness and thus impacts susceptibility and resistance to different types of treatments. Notable biological processes that hypoxia functions in include its regulation of tumor heterogeneity and plasticity. While hypoxia has been reported as a major player in tumor survival and dissemination regulation, the significance of hypoxia inducible factors in cancer stem cell development remains poorly understood. Several reports indicate that the emergence of cancer stem cells in addition to their phenotype and function within a hypoxic tumor microenvironment impacts cancer progression. In this respect, evidence showed that cancer stem cells are key elements of intratumoral heterogeneity and more importantly are responsible for tumor relapse and escape to treatments. This paper briefly reviews our current knowledge of the interaction between tumor hypoxic stress and its role in stemness acquisition and maintenance. Our review extensively covers the influence of hypoxia on the formation and maintenance of cancer stem cells and discusses the potential of targeting hypoxia-induced alterations in the expression and function of the so far known stem cell markers in cancer therapy approaches. We believe that a better and integrated understanding of the effect of hypoxia on stemness during carcinogenesis might lead to new strategies for exploiting hypoxia-associated pathways and their targeting in the clinical setting in order to overcome resistance mechanisms. More importantly, at the present time, efforts are oriented towards the design of innovative therapeutical approaches that specifically target cancer stem cells.

Abstract
Code comprehension is crucial for software maintenance and evolution, but it can be hindered by tiny code snippets that can confuse the developers, called atoms of confusion. Previous studies investigated how atoms impact code comprehension through the perspectives of time, accuracy, and opinions of developers. However, we need more studies evaluating other perspectives and the combination of these perspectives on a common ground through experiments. In our study, we evaluate how the eye tracking method can be used to gain new insights when we compare programs obfuscated by the atoms with functionally equivalent clarified versions. We conduct a controlled experiment with 32 novices in Python and measure their time, number of attempts, and visual effort with eye tracking through fixation duration, fixations count, and regressions count. We also conduct interviews and investigate the subjects' difficulties with the programs. In our results, the clarified version of the code with Operator Precedence reduced the time spent in the region that contains the atom to the extent of 38.6%, and the number of answer attempts by 28%. Most subjects found the obfuscated version more difficult to solve than the clarified one, and they reported the order of precedence to be difficult to validate. By analyzing their visual effort, in the obfuscated version, we observed an increase of 47.3% in the horizontal regressions count in the atom region, making its reading more difficult. The additional atoms evaluated revealed other interesting nuances. Based on our findings, we encourage researchers to consider eye tracking combined with other perspectives to evaluate atoms of confusion and educators to favor patterns that do not impact the understanding and visual effort of undergraduates.

Abstract
Little is known about long-term outcomes of the first episode of psychosis (FEP) other than in the symptomatic domain. We hypothesised that cognitive impairment is associated with poorer multi-domain outcomes at a long-term follow-up of FEP patients. We followed-up 172 FEP patients for a mean of 20.3 years. Ten outcome dimensions were assessed (symptomatic, functional and personal recovery, social disadvantage, physical health, suicide attempts, number of episodes, current drug use, chlorpromazine equivalent doses (CPZ), and schizophrenia/schizoaffective disorder final diagnosis). Cognition was assessed at follow-up. Processing speed and verbal memory deficits showed significant associations with poor outcomes on symptomatic, social functioning, social disadvantage, higher number of episodes, and higher CPZ. Significant associations were found between visual memory impairments were significantly associated with low symptomatic and functional recovery, between attentional deficits and a final diagnosis of schizophrenia/schizoaffective disorder, and between social cognition deficits and poor personal recovery.Lower cognitive global scores were significantly associated with all outcome dimensions except for drug abuse and physical status. Using multiple outcome dimensions allowed for the inclusion of the patients' perspective and other commonly neglected outcome measures. Taken together, cognitive impairment in FEP patients is strongly related to poor performance on several outcome dimensions beyond symptomatic remission.

Abstract
Abstract
Background
Identifying patients with cardiac sarcoidosis (CS) who are at increased risk of sudden cardiac death (SCD) is imperative. Current guideline recommendations for implantable cardioverter-defibrillator (ICD) implantation in patients with CS are based on small observational studies and have not been validated in contemporary cohorts using multimodality cardiac imaging.
Purpose
The aim of this study was to characterize a cohort of patients with tissue-proven cardiac sarcoidosis who underwent multimodality cardiac imaging and identify predictors of appropriate ICD shock and mortality.
Methods
We retrospectively identified subjects with a diagnosis of CS established by clinical/imaging criteria, and tissue biopsy (N=273) seen at our tertiary care center between 2001 and 2021. Clinical characteristics and outcomes were collected from electronic medical records. The primary endpoint of interest was a composite of appropriate ICD shock and all-cause mortality. Secondary endpoints were individual rates of appropriate ICD shock and all-cause mortality. Cox proportional hazard regression analysis was used to identify independent predictors of the outcomes.
Results
Mean age was 59±11 years and 40% were female. Isolated CS was found in 49 subjects (17.9%). The prevalence of traditional cardiovascular risk factors was low. Atrial fibrillation prevalence was high (41%). After a median follow-up of 7.9 years, the rate of appropriate ICD shock and all-cause mortality was 29% (N=79). The 5-year overall survival rate of 97.5%. Age, left ventricular ejection fraction (LVEF), and delayed gadolinium enhancement (DGE) in cardiac magnetic resonance (CMR) were independent predictors of the primary composite endpoint; LVEF and DGE in CMR were independent predictors of appropriate ICD-shock; and LVEF and baseline serum NT proBNP were independent predictors of overall mortality. An LVEF of 47% was identified as the optimal cutoff in predicting the primary composite endpoint. Presence of scar, inflammation or mismatch pattern in positron emission tomography were not significant predictors of the outcomes.
Conclusion
In this large cohort of subjects with CS, we found that the presence of DGE in CMR was the strongest independent predictor of the composite endpoint of appropriate ICD-shock and mortality and of appropriate ICD-shock individually; LVEF by echocardiogram was an independent predictor of the primary and secondary endpoints with an optimal LVEF cutoff for predicting the composite endpoint of 47%.

Abstract
Abstract
Study question
Could the sperm selection by birefringence improve ICSI outcomes in couples with different infertility factors?
Summary answer
Sperm selection by birefringence demonstrated a positive clinical impact on ICSI outcomes in couples with different infertility factors when compared to the conventional sperm selection.
What is known already
Higher sperm DNA fragmentation may affect ICSI outcomes. However, the utilized sperm selection protocols do not allow the evaluation of this parameter. In this sense, the analysis of sperm’s head birefringence has been suggested as an adjuvant of seminal processing in order to select viable sperm for couples with severe male factor. Nevertheless, considering men with normal seminal parameters may also curse with DNA fragmentation, the impact of birefringence on ICSI outcomes of couples with different infertility factors should be investigated.
Study design, size, duration
Retrospective case-control study. One hundred eighty-one couples who underwent ICSI from January 2018 to August 2020 [107 submitted to sperm selection by conventional analysis (Nonbirefringence group) and 74 whose sperm were selected by conventional analysis associated to sperm head birefringence evaluation (Birefringence group)] were included in the study.
Participants/materials, setting, methods
Medical records were assessed for eligibility evaluation and data collection. Clinical characteristics (female age, body mass index, infertility factor, seminal parameters) and ICSI outcomes (eg. fertilization rate, cleavage rate, blastulation rate, number of high quality embryos formed, implantation rate, biochemical pregnancy rate, clinical pregnancy rate per transfer and per initiated cycle) were compared between the groups using (p < 0.05). A multivariate logistic regression model was applied to verify the factors associated with clinical pregnancy.
Main results and the role of chance
Despite the Birefringence group showed higher female age (p = 0.01), lower seminal sperm concentration (p < 0.01) and higher sperm DNA fragmentation (p < 0.01), those patients cursed with higher cleavage rate (p = 0.04), higher clinical pregnancy rate per transfer (p = 0.03) and higher clinical pregnancy rate per initiated cycle (p = 0.02) than the Nonbirefringence group. The logistic regression showed a positive group (Birefrincence) effect on clinical pregnancy achievement.
Limitations, reasons for caution
The unequal inclusion of infertility factors between the groups might represent a bias. In logistic regression analysis, none of those factors interfered with clinical pregnancy, which reinforces the impact of the technique on the results. The endpoint analyzed was clinical pregnancy, while live birth would better reflect ICSI success.
Wider implications of the findings
Sperm selection by birefringence could positively impact ICSI outcomes. Because it is a cheap and easily reproducible technique, it could be combined with conventional ICSI treatments to improve the reproductive chances of those patients.

Abstract
The advent of antimicrobial resistance has added considerable impact to infectious diseases both in the number of infections and healthcare costs. Furthermore, the relentless emergence of multidrug-resistant bacteria, particularly in the biofilm state, has made mandatory the discovery of new alternative antimicrobial therapies that are capable to eradicate resistant bacteria and impair the development of new forms of resistance. Amongst the therapeutic strategies for treating biofilms, antimicrobial photodynamic therapy (aPDT) has shown great potential in inactivating several clinically relevant micro-organisms, including antibiotic-resistant 'priority bacteria' declared by the WHO as critical pathogens. Its antimicrobial effect is centred on the basis that harmless low-intensity light stimulates a non-toxic dye named photosensitizer, triggering the production of reactive oxygen species upon photostimulation. In addition, combination therapies of aPDT with other antimicrobial agents (e.g. antibiotics) have also drawn considerable attention, as it is a multi-target strategy. Therefore, the present review highlights the recent advances of aPDT against biofilms, also covering progress on combination therapy.

Abstract
Introduction Circadian rhythm (CR) dysfunction is a prominent feature in bipolar disorder (BD) and sleep disturbances are characteristic, although not essential to the diagnosis. Objectives To review the literature regarding the CR dysfunction and its impact on the onset and clinical course of BD. Methods We conducted a MEDLINE search using bipolar disorder, circadian rhythm and sleep as keywords, selecting studies written in English. Results CR dysfunction is a trait marker of BD. It’s known that during depressive episodes insomnia is present, with difficulty falling asleep/ maintaining sleep and early awakening. Regarding mania, decreased need for sleep is a critical marker. During the euthymic period significant alterations in sleep pattern have been described. It’s also known that changes in the sleep pattern occur prior to those in mood patterns, indicating that sleep dysregulation may trigger the onset of mood episodes or relapses. Therefore, CR disruption may be associated with the pathophysiology of BD and some factors have already been identified: irregularity of the sleep-wake rhythm, eveningness chronotype, abnormality of melatonin secretion, vulnerability of clock genes and the irregularity of social zeitgeber. Conclusions Disturbances of sleep are pervasive, and an essential feature of BD, worse during mood episodes, but still present during euthymic periods. It remains to determine whether circadian rhythm dysfunction is a trait marker or mood state dependent. Further studies are warranted to clarify this association.

Abstract
Introduction Paraneoplastic syndromes (PS) result from indirect effects of neoplasms. In 50% of the cases the symptoms precede the diagnosis and run independently. PS may involve the peripheral or central nervous system, resulting in symptoms from sensory neuropathies to several neuropsychiatric manifestations. Objectives To review the psychiatric manifestations of paraneoplastic syndromes affecting the nervous system. Methods Selective literature review via PubMed search, using the keywords “paraneoplastic syndromes”, “endrocrine paraneoplastic syndromes”, “neuropsychiatric manifestations”, “limbic encephalitis”. Results The prevalence of PS varies with the type of cancer (<1% for breast and ovarian cancers; 3-5% for small cell lung cancer; 20% for thymomas). The general mechanisms behind PS are related to the production of substances by the tumor that directly or indirectly cause distant symptoms, the depletion of substances or the host response to the tumor. Frequently there are autoimmune phenomena involved, with the production of antineuronal antibodies that recognise various antigens at the nervous system. Paraneoplastic neurological disorders include limbic encephalits that can present subacutely with symptoms of depression, irritability, hallucinations, cognitive impairment associated with sleep alterations, confusion and seizures. Others include psoclonus-myoclonus ataxia syndrome, neuromyotonia and cramp fasciculation syndrome. Metabolic and endocrine paraneoplastic syndromes (hypercortisolism, carcinoid tumors, pancreatic cancer) can result from the production of cytokines and hormones by the tumor and produce mood disorders, confusional states and psychosis. Conclusions PS can be related to various neuropsychiatric manifestations affecting consciousness, cognition, mood and perception. The recognition of this association can alert for the possibility of a cancer diagnosis specially when facing a patient with unusual clinical presentation. Disclosure No significant relationships.

Abstract
Introduction
Anhedonia is a symptom usually, and probably simplistically, defined as the inability to experience pleasure. It is considered one of the core symptoms of depression and a negative symptom of schizophrenia.
Objectives
We intend to explore whether previous studies found common or dissimilar experiences of anhedonia in depression and schizophrenia.
Methods
We performed a review of the published literature on the subject using PubMed. We conducted a search using ‘anhedonia’, ‘schizophrenia’, and ‘depression’ as keywords.
Results
There is different and diverging evidence on the matter. Historical reports associated schizophrenia with trait anhedonia, and depression with state anhedonia. More recently, some authors correlated appetitive anhedonia (lack of interest/desire) with schizophrenia, and consummatory anhedonia (lack of pleasure/enjoyment) with depression, but this was not corroborated by other studies. However, in line with it, there are findings of a normal physiological response to pleasurable stimuli among schizophrenics. Some authors propose that, in schizophrenia, this symptom might not represent an inability to feel pleasure but rather a deficient expression of its experience, as a part of blunted affect. Reward models highlight a deficit in reward learning in depression, but disorganization of reward processing and a focus on irrelevant clues in schizophrenia, which prevent patients from pursuing a pleasurable experience.
Conclusions
There are still limited studies comparing the experience of anhedonia in depression and schizophrenia. There seem to be significant differences between the two, but further studies are needed. In particular, this could be important in screening schizophrenic patients for depression.

Abstract
Introduction We live in a global world, where immigration is no longer just an escape, but also a demand and a desire. Globalization imposes the challenge of recognizing psychiatric illness in the most diverse of patients. Objectives To review the literature about the documentation of ethnic differences and the psychotic symptoms presentation. Methods We performed a MEDLINE search using the key words: ethnic differences and psychotic symptoms. We only included studies with full text published in English. Results
Since the 1970s, some studies have shown that there are differences in the manifestation of psychiatric illness in ethnic minorities. Most recent studies confirm this statement, mainly with an increase in immigration in the 20th century, with the receiving countries having an increase in the number of cases of psychosis (affective and non-affective). Belonging to an ethnic minority increases the risk of psychotic symptoms and experiences, witch is related to the patients perception of discrimination, social differences, family separation and the stress associated with immigration. On the other hand, these groups also have less access to health care. Conclusions Currently, professionals are more aware of the global world and what this implies in the manifestations of psychiatric illnesses. However, more studies will be needed to identify these natural differences. In this way, we will be able to help our patients anywhere and support their families.

Abstract
Introduction Valproic acid is an antiepileptic drug used in different fields of Psychiatry. It is known mostly for its use in managing patients with bipolar affective disorder. In psychiatry of addiction, there is still no approved indications for its usage, but it is widely prescribed in treating alcohol and cocaine abuse, due to the existence of studies in these addictions. Objectives This review aims to clarify the relation between valproic acid and dependences, particularly cocaine. Methods Non-systematic literature review using a PubMed search, using the following key words: “valproate”; “cocaine use”. Results Cocaine dependence can decrease GABA levels in humans. Valproic acid has multiple mechanisms that favour the synthesis of GABA, potentiating its release and postsynaptic GABAergic response. Because of this, valproic acid was found effective in promoting abstinence and in reducing the use of cocaine. There are studies that support the valproic acid’s use in alcohol and cocaine dependences. Valproic acid has been shown to be promising in relapse prevention. It has also showed efficacy in the management of impulsivity and irritability, what makes it useful in managing patients with borderline personality disorder – patients at higher risk for alcohol or substance use disorders. Conclusions Cocaine addiction involves different phenomena and may respond to distinct pharmacologic approaches. Although some studies need to be confirmed by larger clinical trials, valproic acid seems a promising agent as one of some potential treatments for cocaine dependence. Further studies are required in this field to come to more reliable conclusions. Disclosure No significant relationships.

Abstract
Introduction Depression is known to be associated with changes in the hypothalamic-pituitary-thyroid axis and the brain is a major target organ for thyroid hormone. Overt hypothyroidism can cause symptoms compatible with depression. However, its relationship with subclinical hypothyroidism (SCH) is not well established. Objectives To review the literature regarding the effect of levothyroxine therapy among patients with SCH and coexistent depression. Methods We conducted a MEDLINE search using depression, subclinical hypothyroidism and levothyroxine as keywords, selecting studies written in English. Results SCH is defined as an elevated thyroid stimulating hormone with normal peripheric hormone levels. The association between SCH and depression is controversial. Some studies indicate that SCH had the same propensity with overt hypothyroidism, while others report that major affective symptoms are not associated with SCH, but are likely due to independent psychiatric diagnoses, which are common in the general population and occur with similar frequency in patients with SCH. Individuals with SCH are recommended to initiate levothyroxine replacement therapy only when their TSH level is above 10 mIU/L or if symptoms are present. There is a lack of evidence supporting the use of levothyroxine therapy to improve mental health outcomes and the majority of meta-analysis do not show relief of affective symptoms after levothyroxine therapy, among individuals with SCH. Conclusions Routine screening for depressive symptoms among individuals with SCH is important to prevent morbidity. Nevertheless, there is no evidence enduring levothyroxine supplementation in these cases. Further studies, with larger sample sizes and longer follow-up periods are needed to enlighten the potential benefit of this therapy. Disclosure No significant relationships.

Abstract
Introduction Since the second half of the 20th century, studies have been carried out that prove the benefits of the hospital environment in the improvement and recovery of patients. In this way, it would be important to understand what has already been done within the reality of Psychiatry Department. Objectives To review the literature about the documentation of hospital environment influence in patients’ recovery. Methods We performed a MEDLINE search using the key words: hospital environment influence and patients’ recovery or patients healing. We only included studies with full text published in English. Results In the selected articles, we only found studies developed in the Surgery department; in one of them, the authors tested the presence of plants in the patients’ rooms and assessed lower blood pressure values, less pain and less anxiety than the control group; in another, they tested the presence of music and landscape, although there was no difference in terms of pain assessment, there was an improvement in the assessment of the postoperative experience. A review pointed some other aspects that patients linked with their recovery, such as: audio and visual environment; specifically, in anxiety, pain and stress. On the other hand, other studies address the influence of the hospital environment on the satisfaction of health care providers. Conclusions Although hospital environment has already demonstrated an impact on the patient recovery, none (in our review) was developed directly in a Psychiatric Department; further studies are needed to understand the impact on this kind of service.

Abstract
Introduction Pregnancy and the postpartum are generally characterized by positive feelings and expectations but they may also disguise maternal stress and difficulties. These are typical periods for the onset or relapse of psychiatric symptoms and disorders. Even though suicide during pregnancy and postpartum is rare, it is among the leading causes of maternal perinatal mortality. Objectives To provide an overview on the risk of suicide during pregnancy and postpartum. Methods PubMed database was searched using combinations of the terms “suicide”, combined with “pregnancy” and “depression”. Results The major risk factors for suicidal ideation are previous suicide attempts, self-harm, current or past history of psychiatric disorder, young maternal age, being unmarried, an unplanned pregnancy, substance use disorders, lack effective psychosocial support and discontinuation of psychotropic drugs. Pregnant women with suicidality behavior have also an increased risk for various adverse obstetric outcomes, including miscarriage, preterm delivery, maternal hemorrhage, and stillbirth. Furthermore, the postpartum period is often associated with the onset of mood and psychotic disorders with an increased risk of both suicide and infanticide. Women who have suffered from serious psychiatric conditions either after childbirth or in other phases of life should be informed about the possibility of relapse after subsequent pregnancies, thus presenting a higher risk of suicide. Conclusions During pregnancy and postpartum, it is fundamental to investigate suicide risk, including suicidal ideation, thoughts, and intent, especially (but not only) in women affected by mental pathology. Moreover, maternal suicide behaviour affects the child’s neuropsychological development and can also increase the infant´s suicide risk. Disclosure No significant relationships.

Abstract
Fermentation has been used since the Early Neolithic period to preserve foods. It has inherent organoleptic and nutritive properties that bestow health benefits, including reducing inflammation and oxidative stress, supporting the growth of salutogenic microbiota, enhancing intestinal mucosal protection and promoting beneficial immunometabolic health effects. The fermentation of food with specific microbiota increases the production salutogenic bioactive compounds that can activate Nrf2 mediated cytoprotective responses and mitigate the effects of the 'diseasome of aging' and its associated inflammageing, which presents as a prominent feature of obesity, type-2 diabetes, cardiovascular and chronic kidney disease. This review discusses the importance of fermented food in improving health span, with special reference to cardiometabolic diseases.

Abstract
BACKGROUND Few existing evidence-based parent interventions (EBPIs) for prevention and treatment of child and youth mental health disorders are implemented in low-middle-income countries. This study aimed to translate and confirm the factor structure of the Evidence-Based Practice Attitude Scale (EBPAS-15) survey in Brazilian Portuguese with the goal of examining providers' perspective about EBPIs. METHODS We translated and back translated the EBPAS-15 from English to Brazilian Portuguese. Participants were recruited via snowball sampling and data were collected using an online survey from July of 2018 through January of 2020. A confirmatory factor analysis was conducted to determine if the scale retained its original structure. Open-ended questions about providers' perspectives of their own clinical practice were coded using the Theoretical Domains Framework (TDF). Analyses included data from 362 clinicians (318 women, 41 men) from 20 of the 27 states of Brazil. Participants on average were 26.7 years old, held specialist degrees in the field of psychology, actively worked as therapists, and practiced in private clinics. RESULTS The translation of the EBPAS to Brazilian Portuguese retained the same four-factor structure as the English version except for dropping one item from the Divergence domain. When asked about the challenges in their practices, providers generally referred to parents as clients with little skills to discipline their children and lacking knowledge about child development. DISCUSSION The Brazilian version of the EBPAS-15 is promising, but future research should consider using quantitative data alongside qualitative information to better understand providers' attitudes about evidence-based interventions to inform implementation efforts.

Abstract
This study aims at the assessment of mercury (Hg)-selenium (Se) antagonism in fish. For this purpose, rainbow trout fish (Oncorhynchus mykiss) were exposed to methylmercury (MeHg) under controlled conditions, in the presence or absence of selenomethionine (SeMet) using an in-house prepared diet (enriched with MeHg and SeMet at 0.2 μg/g and 5.0 μg/g, respectively). The total duration of the exposure study was 3 months. Fish was sampled and analysed for total Se (SeT) and total mercury (HgT) content after 1, 2 and 3 months of exposure. Six feeding protocols were compared, depending on the exposure type: (i) no MeHg nor SeMet exposure (control group); (ii) exposure to SeMet solely; (iii) exposure to MeHg solely; (iv) exposure to both MeHg and SeMet; (v) exposure first to MeHg during 1 month and then to SeMet during 2 months and (vi), exposure to SeMet during 1 month and then to MeHg for 2 months. The levels of SeT and HgT in the fish (control and supplemented with MeHg/SeMet) were measured by inductively coupled plasma-mass spectrometry (ICPMS). Steadily (linear) bioaccumulation of MeHg in the fish muscle occurred when the fish were exposed individually to this species during the period. The bioaccumulation of MeHg is diminished when the fish are firstly exposed to SeMet and then to MeHg, hence indicating the MeHg detoxification due to SeMet supplementation.

Abstract
Little is known about the pathophysiological mechanisms of relapse in first-episode schizophrenia, which limits the study of potential biomarkers. To explore relapse mechanisms and identify potential biomarkers for relapse prediction, we analyzed gene expression in peripheral blood in a cohort of first-episode schizophrenia patients with less than 5 years of evolution who had been evaluated over a 3-year follow-up period. A total of 91 participants of the 2EPs project formed the sample for baseline gene expression analysis. Of these, 67 provided biological samples at follow-up (36 after 3 years and 31 at relapse). Gene expression was assessed using the Clariom S Human Array. Weighted gene co-expression network analysis was applied to identify modules of co-expressed genes and to analyze their preservation after 3 years of follow-up or at relapse. Among the 25 modules identified, one module was semi-conserved at relapse (DarkTurquoise) and was enriched with risk genes for schizophrenia, showing a dysregulation of the TCF4 gene network in the module. Two modules were semi-conserved both at relapse and after 3 years of follow-up (DarkRed and DarkGrey) and were found to be biologically associated with protein modification and protein location processes. Higher expression of DarkRed genes was associated with higher risk of suffering a relapse and early appearance of relapse (p = 0.045). Our findings suggest that a dysregulation of the TCF4 network could be an important step in the biological process that leads to relapse and suggest that genes related to the ubiquitin proteosome system could be potential biomarkers of relapse.

Abstract
Abstract
Background/Introduction
Artificial intelligence (AI) applied to 12-lead ECG can identify left ventricular ejection fraction (EF) ≤35% with a sensitivity and specificity of 86.3% and 85.7%, respectively. Whether AI algorithms trained on 12-lead can accurately predict EF from single-lead ECGs (recorded by a smart stethoscope) remains unknown. This could facilitate point-of-care screening for low EF during routine clinical examination.
Purpose
First independent multicentre real-world UK National Health Service (NHS) prospective validation of 12-lead-ECG-trained AI algorithm applied to single-lead ECG recorded by a smart stethoscope, with AI algorithm tuned to detect EF ≤40%.
Methods
Prospective recruitment of unselected patients attending for echocardiography across six urban NHS hospital sites (UK). In addition to transthoracic echocardiogram (routine care), all participants had 15 seconds of supine, single-lead ECG recorded at six different positions (figure), encompassing standard anatomical positions for cardiac auscultation. A convolutional neural network (CNN) previously trained on 35,970 independent pairings of 12-lead-ECG and echocardiograms was retrained to use the single-lead ECG as input. Accuracy of CNN detection of low EF (binary ≤40%) is reported at a threshold of 0.5 against gold-standard; echo-determined percentage EF.
Results
Among 353 patients recruited (mean age 63±17; 58% male, 43.1% non-white), 309 (87.5%) had an EF >40%, and 44 (12.5%) had EF ≤40%. The best single recording position in isolation was position 3 (sensitivity 57.9% [42.2–73.6], specificity 86.3% [82.2–90.3]). Taking any of the six positions performed during the examination as predicting EF ≤40%, this achieved a sensitivity of 81.2% and specificity of 61.5%.
Conclusion(s)
In this first prospective multicentre validation study the retrained AI algorithm reliably detected low EF from single-lead ECGs acquired using a novel ECG-enabled stethoscope in standard auscultation positions. The ability to identify patients with possible low EF during routine physical examination addresses a significant unmet clinical need in point-of-care ruling in/out of heart failure, and has potential to provide broader population-level screening for asymptomatic cardiovascular disease.

Abstract
The C preprocessor is widely used in practice. Conditional compilation with #ifdef annotations allows developers to flexibly introduce variability in their programs. Developers can use disciplined annotations, entirely enclosing full statements with preprocessor directives, or undisciplined ones, enclosing only parts of the statements. Despite some debate, there is no consensus on whether a developer should use exclusively disciplined annotations. While one prior study found undisciplined annotations more time-consuming and error-prone, another study found no difference between disciplined and undisciplined annotations regarding task completion time and accuracy. In this article, we evaluate whether three fine-grained refactorings to discipline #ifdef annotations correlate with improvements in code comprehension and visual effort with an eye tracker. We conduct a controlled experiment with 64 human subjects who were majoritarily novices in the C programming language. We observed statistically significant differences for two refactorings to discipline annotations with respect to the analyzed metrics (time, fixation duration, fixation count, and regressions count) in the code regions changed by each refactoring.

Abstract
Introduction Cognitive deficits are common, clinically relevant and closely linked to poor functional outcomes in everyday functioning in patients with schizophrenia and other psychoses. Objectives To ascertain to which extent a polydiagnostic assessment of schizophrenia is associated with clinically-derived criteria of cognitive impairment and gold-standard neuropsychological assessment. Methods We assessed 98 patients with a psychotic disorder. We tested if patients met criteria for schizophrenia according to five diagnostic classifications: Krapelin, Bleuler, Schneider, ICD-10 and DSM-IV. Also, we applied a set of clinically-derived criteria to assess cognitive impairment associated with psychosis (CIAPs). Gold-standard neuropsychological assessment was administered, covering the cognitive domains included in the MATRICS Cognitive Battery: attention, processing speed, verbal memory, visual memory, working memory, executive function and social cognition. MANOVAs were performed to test the association between polydiagnostic and clinically-derived criteria and neuropsychological assessment. Results ![]()
MANOVA profile analyses revealed that patients who met CIAPs criteria showed cognitive impairment in all the cognitive domains except for social cognition. Patients diagnosed with Kraepelin’s criteria showed significant differences in processing speed, visual memory, working memory and GCI. Patients fulfilling Bleuler and DSM-IV criteria showed significant deficits in processing speed and verbal memory, respectively. Schneider and ICD-10 diagnostic criteria did not reveal differences in cognition between patients who fulfilled these criteria. Conclusions CIAPs criteria were the most accurate classifying patients with cognitive impairment, followed by Kraepelin’s criteria, which were the ones among diagnostic criteria which better differentiated patients regarding cognitive impairment. These criteria take into consideration the outcome in addition to symptoms.

Abstract
Abstract
Background
T1 mapping is a magnetic resonance imaging (MRI) technique that enables the identification of myocardial structural changes during acute ischemic injury. However, it is not known whether these structural changes are present in patients with chronic effort induced ischemia.Thus, we sought to document the possible T1 mapping changes in chronic coronary artery disease (CAD) patients with documented myocardial ischemia.
Methods
Multivessel CAD patients from MASS V Trial with indication of myocardial revascularization, were evaluated for the presence of ischemia by myocardial scintigraphy. MRI with T1 mapping was performed in all patients. Based on the results of the scintigraphy, the myocardial segments were identified as ischemic and non-ischemic segments. The corresponding segments of scintigraphy and MRI were compared in relation to native T1 map (NT1), post-contrast T1 (CAT1) and extracellular volume (ECV).
Results
Of the 720 myocardial segments analyzed, there were 161 ischemic and 559 non-ischemic segments. Comparing ischemic vs non-ischemic segments, respectively, NT1 was 1022.7 (980.0–1052.0) versus 1029.3 (985.0–1066.3), p=0.57, ECV results were 25.4 (24.0–28.1) versus 26.4 (25.3–29.9), p=0.75 and CAT1 results were 492 (461.9–515.4) versus 488 (469.2–521.7), p=0.09. Myocardial segments supplied by obstructive coronary arteries were compared to those supplied by non-obstructive coronary arteries in relation to NT1 and ECV. NT1 values in obstructive and non-obstructive territories were, respectively, 1024.7 (998.5–1043.5) versus 1036.8 (1008.6–1046.9), p=0.30 and ECV results were 26.8 (24.4–29.9) versus 26.8 (24.4–30.0), p=0.90.
Conclusion
In this study, MRI identified structural similarities between chronic ischemic myocardium compared to the non-ischemic myocardium. This finding supports myocardial tissue stability in the presence of stress induced ischemia.

Abstract
Abstract
Background
At 28th February 2020, local public health authorities were notified that an occupational activity center headed to adult individuals with disabilities, in Guimarães (Portugal), had several cases of users vomiting or with diarrhea during that week, requesting control measures.
Methods
An outbreak investigation was carried out, with case definition being someone with nausea, vomiting and/or diarrhea. An epidemic curve was made with the number of cases per date of symptoms onset. Attack rate was calculated as the number of cases in the occupational activity center divided by the number of people in the same center.
Results
Mild, self-limited acute symptoms of nausea, vomiting and/or diarrhea were identified in 18 individuals that attended the occupational activity center. The first case developed symptoms on 24th February (day 0); the second case appeared about 24 hours after; the peak occurred at day 4 with seven cases. Attack rate was 27% among users and 15% among monitors. The mean age was 40 years. Two cases went to the emergency department and were clinically diagnosed with acute viral gastroenteritis, no further care needed. Meals were served at a neighbor building, shared with another rehabilitation institution. The rehabilitation institution reported zero cases. Additionally, Hazard Analysis and Critical Control Point process was fully accomplished.
Conclusions
Clinical and epidemiological findings suggest a probable viral outbreak with person-to-person transmission. The incubation period is consistent with norovirus, the most common agent of viral gastroenteritis. No biological samples were collected, because symptoms were mild and there was no chance to do it. Environmental samples were not collected. Preventive hygiene measures were immediatly enhanced, namely hand washing, appropriate disinfection of contaminated surfaces and isolation if symptomatic. These measures are highly efficient breaking the chain of infection and that was obtained.
Key messages
Epidemiological findings are at the core of an outbreak investigation and support immediate implemention of effective control measures. Although laboratory results are important, they are not always available for outbreak investigation.

Abstract
Abstract
Introduction
The pregnancy-puerperal cycle is defined as a moment that involves physical, psychological and social changes. There are pregnancies that require specialized care and attention due to the presence of risk factors that may be prior to pregnancy and / or that may be associated with the pregnancy condition itself, which characterize them as high-risk pregnancies. Currently, prenatal care with risk stratification is the main care strategy for pregnant women, once the risk classification is identified, it is possible to promote interventions according to the health needs of each pregnant woman. For this, the risk assessment is carried out at each prenatal consultation, so that, depending on the course of pregnancy, hospitalization becomes necessary. The diagnosis of high-risk pregnancies accompanied by hospitalization has impacts on the woman's life, such as loss of autonomy, a sense of failure and the incidence of greater care and interventions by the health team and the family that can configure practices to control their bodies.
Objective
This work aims to identify the hospitalization process during high-risk pregnancy as a space for the production of projects, resistance and protagonism through the protocols and regulations that configure the hospital context.
Methodology
This is an exploratory analysis of a qualitative approach in public health. A reference maternity hospital in high-risk pregnancy located in a teaching hospital in Greater Vitória was chosen. It will be used to define sampling for convenience. The data will be collected through semi-structured interviews and on-site observations by the researcher. The data analysis methodology used will be content analysis.
Expected Results
It is expected to understand the various practices of protagonism and resistance that permeate the care of hospitalized pregnant women.
Key messages
This work has an impact on the improvement of the maternal and child care network of the public health system in Brazil. This work allows to evaluate the quality of the assistance provided in the public maternity.

Abstract
Ocular syphilis can simulate various ophthalmic pathologies with multiple possible ophthalmic findings. Timely treatment of these patients can minimize visual damage, but its diagnosis is often a challenge for the ophthalmologist. We review a case report of a 45-year-old man with a rare and atypical clinical presentation of ocular syphilis, its clinical and imaging characteristics, its diagnosis, treatment and evolution. The patient presented with bilateral painless loss of vision, photopsia and peripheral scotomas with about 1 week evolution. There were no signs of ocular inflammation. The complementary ophthalmic study revealed an acute zonal occult outer retinopathy-like ("AZOOR-like") presentation. Ocular syphilis does not always present with ocular inflammation and its presentation as "AZOOR-like" is very rare. So, we should always maintain a high index of suspicion for this condition, as early diagnosis and treatment are essential for a better prognosis.

Abstract
BACKGROUND Intraperitoneal administration of ceftriaxone maintains therapeutic abdominal concentrations for 24 hours in healthy horses. Therefore, it is a possible treatment for septic peritonitis. The aim of this study was to evaluate the efficacy of ceftriaxone as an adjuvant treatment in horses with septic peritonitis. METHODS Twenty-six horses with clinical signs, sonography and/or laboratory findings of septic peritonitis were included. Peritoneal fluid was collected for microbiological culture and in vitro microbial sensitivity profile assessment. Daily intraperitoneal administration of ceftriaxone (25 mg/kg) was initiated with supportive and systemic antimicrobial treatment. The animals were divided into three groups: group 1-gastrointestinal tract injuries and abdominal surgery (excluding perforations/ruptures); group 2-not related to changes in the gastrointestinal tract; group 3-secondary to intestinal rupture and/or faeces contamination. RESULTS The mean success rate of the treatment was 77 per cent (20/26 animals), with success rates of 84.6 per cent in group 1; 87.5 per cent, group 2; and 40 per cent, group 3. CONCLUSIONS This is the first study to report adjuvant intraperitoneal treatment ceftriaxone for septic peritonitis in horses and indicates that this treatment can successfully treat septic peritonitis in horses.

Abstract
Abstract
Introduction
Doxorubicin (Dox) is an anthracycline commonly used to treat many types of cancer; unfortunately this chemotherapeutic agent induces many side effects such as cardiotoxicity leading to dilated cardiomyopathy (DCM). The cardiotoxicity of Dox has been related to reactive oxygen species generation, DNA intercalation, topoisomerase II inhibition and bioenergetics alterations leading to cardiomyocyte death.
Objective
Nowadays the challenge is to find new treatment options aiming at reducing Dox cardiotoxicity. Epac (exchange protein directly activated by cAMP) signaling could be worth investigating as Epac activates small G proteins which are known to be involved in Dox-induced cardiotoxicity.
Methods
We investigated the time/dose-dependent Dox effect on Epac signaling in both in vivo mice model (C57Bl63/ Knock-out Epac1 mice, iv injections, 12mg/kg cumulative dose) and in vitro (primary culture of neonatal rat cardiomyocytes (NRVM, 24h, Dox 1μM).
Results
In vivo, Dox-treated mice developed a DCM associated with Ca2+ homeostasis dysfunction (increase of Ca2+ waves and Ca2+ leaks). In vitro, as measured by flow cytometry and western blot, Dox (1μM) induced DNA damages and cell death in NRVM. This cell death is associated with apoptotic features including mitochondrial membrane permeabilization, caspase activation and cell size reduction. The inhibition of Epac1 (ESI09, CE3F4) decreased Dox-induced DNA damage, loss of mitochondrial membrane potential, apoptosis and finally cardiomyocyte death. Moreover, in vivo, Epac1 KO mice were protected against Dox-induced cardiotoxicity by unaltered cardiac function (no DCM) and calcium homeostasis at 15 weeks post-treatment.
Conclusion
Inhibition of Epac1 could be a valuable therapeutic strategy to limit Dox-induced cardiomyopathy during cancer chemotherapy. Indeed, preliminary data show also that preventing Dox-induced cardiotoxicity, the inhibition of Epac1 can also potentiate cancerous cells death.

Abstract
This paper presents a payload designed to perform semi-autonomous contact inspection tasks without any type of positioning system external to the UAV, such as a global navigation satellite system (GNSS) or motion capture system, making possible inspection in challenging GNSS- denied sites. This payload includes two LiDAR sensors which measure the distance between the UAV and the target structure and their inner orientation angle. The system uses this information to control the approaching of the UAV to the structure and the contact between both, actuating over the pitch and yaw signals. This control is performed using a hybrid automaton with different states that represent all the possible UAV status during the inspection tasks. It uses different control strategies in each state. An ultrasonic gauge has been used as the inspection sensor of the payload to measure the thickness of a metallic sheet. The sensor requires a stable contact in order to collect reliable measurements. Several tests have been performed on the system, reaching accurate results which show it is able to maintain a stable contact with the target structure.

Abstract
ABSTRACT Trauma or disease inflicted by tissue injuries may cause tissue degeneration. The use of biomaterials for direct or indirect repair has emerged as a promising alternative, and has become an important research topic. The pequi fruit (Caryocar brasiliense Camb.) has shown antifungal, antibacterial, anti-inflammatory, healing, antitumor, and antioxidant properties. The objective of this study was to develop a new biomaterial using a combination of collagen, gelatin, and pulp pequi oil, and to evaluate its biocompatibility in comparison with that of biomaterials produced without pulp pequi oil. Membranes were prepared from a mixture of bovine tendon collagen, commercial gelatin, and pulp pequi oil. The inflammatory and cicatricial processes were assessed via histopathology of the tissue interface/implants in the subcutaneous tissues and quantitative evaluation of leukocyte and collagen production in Wistar rats. It was observed that the presence of pequi oil reduced the amount of foreign-body giant cells and favored the recruitment of fibroblasts (P< 0.01), thereby promoting greater production of collagen membrane than that in the membranes of control samples. Therefore, it can be concluded that the addition of pequi oil improved the biocompatibility of collagen and accelerated the healing process.

Abstract
BACKGROUND The incidence rates of melanoma have risen to worrying levels over the last decade. Delayed diagnosis, due to faults on the detection stage, indicates the necessity of new aiding diagnosis techniques. Since metabolic activity is highly connected to neoplasia formation, a detection technique that focuses its results on vascular responses, as Infrared thermal (IRT), seems to be a viable option. MATERIALS AND METHODS Static and dynamic (cooling) thermal images of melanoma and melanocytic nevi lesions were collected and analysed to retrieve thermal parameters characteristic of this skin lesion types. The steady-state and dynamic variables were tested separately with different machine learning classifiers to verify whether the distinction of melanoma and nevi lesions was achievable. RESULTS The differentiation of both types of skin tumours was doable, achieving an accuracy of 84.2% and a sensitivity of 91.3% with the implementation of a learner based on support vector machines and an input vector composed by static variables. CONCLUSION The use of IRT for skin tumour classification is achievable, but some improvement is needed to raise the metrics of sensitivity and specificity. For future work, it is recommended the study of dynamic parameters for the classification of other types of skin neoplasia.

Abstract
The aim of this study was the development of a novel and effective antibacterial formulation combining selected phytochemical compounds (quercetin, cuminaldehyde, indole-3-carbinol and vanillic acid) with ethylenediaminetetraacetic acid (EDTA), an aminopolycarboxylic acid. The antibacterial activity of the combinations was evaluated against Escherichia coli and Staphylococcus epidermidis in planktonic and sessile states as single and dual species. The compounds when applied individually demonstrated modest antibacterial activity. Nevertheless, synergy was observed when EDTA was combined with the selected phytochemicals, particularly with cuminaldehyde and indole-3-carbinol. These combinations were evaluated against single- and dual-species biofilms. An inactivation of 100% was obtained for almost all the biofilms, with E. coli biofilms showing the highest resistance. This study allowed the discovery of novel formulations of phytochemical compounds with antibacterial activity against E. coli and S. epidermidis single- and dual-species biofilms at concentrations close to the minimum bactericidal concentration. SIGNIFICANCE AND IMPACT OF THE STUDY: The synergistic combinations of EDTA and cuminaldehyde or indole-3-carbinol were effective against single- and dual-species E. coli and S. epidermidis planktonic cells and biofilms. The overall results highlight the role of phytochemical products as a green and sustainable source of antimicrobial potentiators to control bacteria in both planktonic and sessile states.

Abstract
Individual changes over time in cognition in patients with psychotic disorders have been studied very little, especially in the case of first episode psychosis (FEP). We aimed to establish whether change in individual trajectories in cognition over 2 years of a sample of 159 FEP patients was reliable and clinically significant, using the reliable change index (RCI) and clinically significant change (CSC) methods. We also studied a sample of 151 matched healthy controls. Patients and controls were assessed with a set of neuropsychological tests, as well as premorbid, clinical and functionality measures. We analysed the course of cognitive measures over time, using analysis of variance, and the individual trajectories in the cognitive measures with the regression-based RCI (RCISRB) and the CSC. The RCISRB showed that between 5.4 and 31.2% of the patients showed deterioration patterns, and between 0.6 and 8.8% showed improvement patterns in these tests over time. Patients showing better cognitive profiles according to RCISRB (worsening in zero to two cognitive measures) showed better premorbid, clinical and functional profiles than patients showing deterioration patterns in more than three tests. When combining RCISRB and CSC values, we found that less than 10% of patients showed improvement or deterioration patterns in executive function and attention measures. These results support the view that cognitive impairments are stable over the first 2 years of illness, but also that the analysis of individual trajectories could help to identify a subgroup of patients with particular phenotypes, who may require specific interventions.

Abstract
OBJECTIVE To describe the perceptions of patients, their caregivers, and their healthcare providers to the development of a new specific instrument for assessment of the quality of life (QoL) in patients with mucopolysaccharidoses (MPS) using a qualitative focus group (FG) design. FGs were held in two Brazilian states (Rio Grande do Sul and Rio de Janeiro). RESULTS Three versions of the new instrument were developed, each for a different age group: children (age 8-12 years), adolescents (age 13-17), and adults (age ≥ 18). The FGs mostly confirmed the relevance of items. All FGs unanimously agreed on the facets: School, Happiness, Life Prospects, Religiosity, Pain, Continuity of Treatment, Trust in Treatment, Relationship with Family, Relationship with Healthcare Providers, Acceptance, and Meaning of Life. The overall concept of QoL (as proposed by the WHO-World Health Organization) and its facets apply to this patient population. However, other specific facets-particularly concerning clinical manifestations and the reality of the disease-were suggested, confirming the need for the development of a specific QoL instrument for MPS.

Abstract
BACKGROUND Low- and middle-income countries (LMICs) face a lack of epidemiological data. The development of high-quality surveys is a key research priority in countries such as Brazil. Our aim is to discuss the difficulties in conducting a longitudinal epidemiological survey in a pilot study of a school-based sample in São Paulo. METHODS Data came from a cohort of school-attending adolescents in two neighborhoods with different levels of urbanicity in São Paulo. Students born in 2002 and in the 7th grade during 2014 were recruited from nine public schools. Adolescents and caregivers were interviewed separately at baseline and at one year follow-up, using several instruments, including the Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Version (K-SADS-PL). RESULTS Achieving unbiased sampling, keeping an updated register of participants' contact information, using a full clinical interview without an algorithm for its scoring, and maintaining a highly-trained research team were among the difficulties faced. CONCLUSION Working closely with community leaders, organizing group efforts to perform interviews, using a short, easy to understand instrument and providing some reward for participants were identified as alternatives to dealing with these difficulties, useful not only in Brazil, but also in other LMICs.
