Abstract
Electrophysiology has proven invaluable to record neural activity, and the development of Neuropixels probes dramatically increased the number of recorded neurons. These probes are often implanted acutely, but acute recordings cannot be performed in freely moving animals and the recorded neurons cannot be tracked across days. To study key behaviors such as navigation, learning, and memory formation, the probes must be implanted chronically. An ideal chronic implant should (1) allow stable recordings of neurons for weeks; (2) allow reuse of the probes after explantation; (3) be light enough for use in mice. Here, we present the "Apollo Implant", an open-source and editable device that meets these criteria and accommodates up to two Neuropixels 1.0 or 2.0 probes. The implant comprises a "payload" module which is attached to the probe and is recoverable, and a "docking" module which is cemented to the skull. The design is adjustable, making it easy to change the distance between probes, the angle of insertion, and the depth of insertion. We tested the implant across eight labs in head-fixed mice, freely moving mice, and freely moving rats. The number of neurons recorded across days was stable, even after repeated implantations of the same probe. The Apollo implant provides an inexpensive, lightweight, and flexible solution for reusable chronic Neuropixels recordings.

Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Abstract
Mixing/blending is a crucial operation in the manufacturing of solid drug products in the pharmaceutical industry. Although usually described and controlled in specific steps, blending is also inherent to other operations such as transference of materials and equipment feeding systems. This study aimed to investigate a simple and fast wettability testing procedure capable to foresee potential over-blending effects of lubricants occurring during manufacturing of solid dosage forms. An industrial batch blend was submitted to two mixing mechanisms studies (diffusion and shear) during increasing time periods, and the developed wettability testing procedure was applied to assess their impact on blend water uptake. Capsules filled with these blends were tested for dissolution and disintegration. The method was applied to capsules with known dissolution results manufactured at industrial scale. Results demonstrated that processes inducing shear stress led to less permeable blends with consequent retardation on capsules dissolution of at least 35% in the tested timepoints and obtained study metrics above 500 s. Moreover, disintegration testing was not able to detect non-compliant dissolutions, while the proposed wettability testing procedure proved to be able to identify performance failures. Wettability results correlate the effect of mixing mechanisms to capsules dissolution performance, evidencing that this technique can be applied in pharmaceutical industry to evaluate possible over-blending effects.

Abstract
BACKGROUND The accuracy with which healthcare professionals (HCPs) and risk prediction tools predict outcomes after major lower limb amputation (MLLA) is uncertain. The aim of this study was to evaluate the accuracy of predicting short-term (30 days after MLLA) mortality, morbidity, and revisional surgery. METHODS The PERCEIVE (PrEdiction of Risk and Communication of outcomE following major lower limb amputation: a collaboratIVE) study was launched on 1 October 2020. It was an international multicentre study, including adults undergoing MLLA for complications of peripheral arterial disease and/or diabetes. Preoperative predictions of 30-day mortality, morbidity, and MLLA revision by surgeons and anaesthetists were recorded. Probabilities from relevant risk prediction tools were calculated. Evaluation of accuracy included measures of discrimination, calibration, and overall performance. RESULTS Some 537 patients were included. HCPs had acceptable discrimination in predicting mortality (931 predictions; C-statistic 0.758) and MLLA revision (565 predictions; C-statistic 0.756), but were poor at predicting morbidity (980 predictions; C-statistic 0.616). They overpredicted the risk of all outcomes. All except three risk prediction tools had worse discrimination than HCPs for predicting mortality (C-statistics 0.789, 0.774, and 0.773); two of these significantly overestimated the risk compared with HCPs. SORT version 2 (the only tool incorporating HCP predictions) demonstrated better calibration and overall performance (Brier score 0.082) than HCPs. Tools predicting morbidity and MLLA revision had poor discrimination (C-statistics 0.520 and 0.679). CONCLUSION Clinicians predicted mortality and MLLA revision well, but predicted morbidity poorly. They overestimated the risk of mortality, morbidity, and MLLA revision. Most short-term risk prediction tools had poorer discrimination or calibration than HCPs. The best method of predicting mortality was a statistical tool that incorporated HCP estimation.

Abstract
Natural or industrial hexavalent chromium water pollution continues to be a worldwide unresolved threat. Today, there is intense research on new active and cost-effective sorbents for Cr(VI), but most still exhibit a critical limitation: their powdered nature makes their recovery from water cost and energy consuming. In this work, Al(OH)3, MIL-88-B(Fe), and UiO-66-NH2 Cr(VI) sorbents were immobilized into a poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymeric substrate to develop an easily reactivable and reusable water filtering technology. The immobilization of the sorbents into the PVDF-HFP porous matrix modified the macro and meso-porous structure of the polymeric matrix, tuning in parallel its wettability. Although a partial blocking of the Cr(VI) adsorptive capacity was observed for of Al(OH)3 and MIL-88-B(Fe) when immobilized into composite membranes, PVDF-HFP/UiO-66-NH2 filter (i) exceeded the full capacity of the non-immobilized sorbent to trap Cr(VI), (ii) could be reactivated and reusable, and (iii) it was fully functional when applied in real water effluents.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
Introduction
While alcohol-induced psychotic disorder (AIPD) is a well-recognised clinical disorder, relativery little is known about aspects such as epidemiology, course and treatment of the condition. Current evidence suggests AIPD can be clinically distinguised from alcohol-withdrawal delirium and schizophrenia. AIPD is associated with high comorbidity with other psychiatric disorders, high re-hospitalization and mortality rate, namely suicidal behaviour.
Objectives
The objetive of the study was to examine the correlates, clinical features, psycopathology, and short-term response in an inpatient sample with alcohol-induced psychotic disorder, predominant hallucinations (ICD-10 F10.52) admitted to Centro Hospitalar Psiquiátrico de Lisboa.
Methods
We collected retrospectively data from all admitted patients to our Alcohol Unit between January 2010 and January 2020 with the diagnosis of AIPD. The exclusion criteria were: presence of preexisting psychotic disorder, delirium, or other substance use disorders. We characterized our sample in Demographic categories, Clinical categories, Treatment and Short-term course.
Results
A total of 113 subjects were included in the study. The prevalance of alcoholic hallucinosis was found to be 1.3% of all patients who received inpatient treatment. Most individuals reported auditory hallucinations, that iniciated when they decrease their alcohol intake, and 1 in 4 had past episodes of AIPD.
Conclusions
There are specific challenges in studiyng AIPD, such as the relatively rarity of the disorder, its often transient nature and high levels of comorbidity. A high degree of recurrence and morbidity indicates a need to prevent, and intervene early with an abstinent-oriented management goal.

Abstract
In recent years, environmental factors, particularly humidity, have been used to inform influenza prediction models. This study aims to quantify the relationship between humidity and influenza incidence at the state-level in the contiguous United States. Piecewise segmented regressions were performed on specific humidity data from NASA's Atmospheric Infrared Sounder (AIRS) and incident influenza estimates from Google Flu Trends to identify threshold values of humidity that signal the onset of an influenza outbreak. Our results suggest that influenza incidence increases after reaching a humidity threshold that is state-specific. A linear regression showed that the state-specific thresholds were associated with annual average humidity conditions (R 2 = 0.9). Threshold values statistically significantly varied by region (F-statistic = 8.274, p < 0.001) and of their 36 pairwise combinations, 13 pairs had at least marginally statistically significant differences in their means. All of the significant comparisons included either the South or Southeast region, which had higher humidity threshold values. Results from this study improve our understanding of the significance of humidity in the transmission of influenza and reinforce the need for local and regional conditions to be considered in this relationship. Ultimately this could help researchers to produce more accurate forecasts of seasonal influenza onset and provide health officials with better information prior to outbreaks.

Abstract
Introduction The process of emotional regulation allows the patient to deal with various situations throughout life, since it includes the ability to create and control emotions, in order to guide action and interaction with others. However, people with alcohol use disorder (AUD) is not always able to give appropriate responses to surronding situations in the face of certain specific emotions. Objectives We aimed to evaluate the use of emotional regulation strategies in people with AUD. Methods A descriptive and correlational study was conducted. A sociodemographic questionnaire, that included variables to assess aspects related to AUD, and the Emotion Regulation Questionnaire were used. Results The sample had 25 participants, mostly male, average age of 46.68 years. 44% were married, and most cases had an withdrawal time larger than 3 months. Regarding emotional regulation strategies, it was found that the participants resort more to cognitive reassessment (M=26.59,SD = 7.54), compared to emotional suppression (M = 15.16, SD = 5.03). Statistically significant differences were found between genders in relation to cognitive reassessment (U = 29.00; p = 0.02). No correlations were found between withdrawal time, treatment time, cognitive reevaluation and emotional suppression. Conclusions Results show differences between gender, and the absence of a relationship between educational qualifications in cognitive reassessment, contradicting previous findings on general Portuguese population. This data points to the need to implement intervention programs in this population, taking into account the gender variable, and including the development of the ability to identify and express emotions, as well as of strategies to deal with emotional aspects.

Abstract
Introduction Attention deficit and hyperactivity disorder (ADHD) and bipolar disorder (BD) are two of the most prevalent psychiatric disorders presenting in children and adults, respectively. Reported co-occurrence of ADHD and BD in adulthood is higher than would be expected by chance, with great impact on prognosis and treatment. Since features of both entities can overlap, careful assessment of these patients is crucial. Objectives To understand the relation between BD and ADHD, and how co-occurrence impacts clinical evaluation. Methods
Bibliographic research was made through the PubMed/NCBI database. No time limit was specified on the search. Pertinent manuscripts were individually reviewed for additional relevant citations. Results ADHD influences the course and manifestations of BD, regardless of its presence later in adulthood. There is a 3-fold increase of ADHD co-occurrence in individuals with BD when compared to normal population, and ADHD seems to co-occur in about 20% of BD patients (even after correction for overlapping symptoms). Features which may suggest simultaneous diagnosis are: earlier occurrence of BD-related symptoms (especially manic or hypomanic states), more severe course of the mood disorder, less adherence to treatment and higher functioning impact. This makes for a worse prognosis, with increased suicidal risk in these patients. Conclusions The co-occurrence of BD and ADHD may represent a distinct clinical phenotype, with recent findings highlighting the presence of common neurobiological mechanisms. Accordingly, patients with BD should be screened for ADHD and viceversa. There is no consensus for treatment of ADHD-BD patients, with further studies being necessary to better define and define possible therapeutic approaches.

Abstract
Introduction The word motivation derives from the Latin movere, which means to move. In psychiatry, it is an isolated phenomenon found in the substrate of several pathologies, and may be part of an heterogeneous dimensional spectrum. However, there is no unique definition for it, nor a targeted approach. In addictive disorders motivation gains a fundamental role, both as a precipitant of abuse as in its withdrawal. Objectives To review the literature about the concept of motivation and its implications on the psychopathology, especially on addictive disorders. Methods Narrative review on PubMed/MEDLINE, using the keywords “motivation” AND “psychopatology” AND “addiction”. Articles in English and Portuguese were included. Results Three main perspectives were found addressing the concept of motivation in psychopathological terms: psychological, neurobiological and phenomenological. The first describes motivation as the energizing of behaviour in pursuit of a goal. Neurobiology says motivational drive is dependent on the concentration of extrasynaptic dopamine. In phenomenological terms, the concept stands for the web of solicitations that make a certain situation feel in a certain way for the subject. In addictive disorders, learning about what leads to reward, exaggeration in representing those values, and dominance in being guided by those representations lead to alterations on motivation mechanisms. Conclusions Motivation is described from different perspectives. Although it is recognized as a fundamental piece in addictive disorders, besides motivational interview model, there are no pharmacological approaches aimed to improving motivation. The recognition of motivation as a concrete psychopathological alteration, and its measure through psychopathological instruments, could optimize the patient’s approach.

Abstract
Introduction Epilepsy has long been considered a risk factor for psychosis, and studies estimate that up to 80% of patients with epilepsy will experience a psychotic episode at some point in the course of their disease. However, data on the treatment of psychotic disorders in epilepsy is limited and the management of these problems is still founded on individual clinical experience. Objectives To assess evidence pertaining psychosis related to epilepsy, especially its risks factors and treatment approaches available. Methods Bibliographic research was made through the PubMed/NCBI database. No time limit was specified on the search. Pertinent manuscripts were individually reviewed for additional relevant citations. Results Recent literature shows a prevalence in psychotic disorders of 5.6%, and up to 7% in patients with epilepsy. So far, mechanisms of psychosis in epileptic patients remain unknown. Risk factors are earlier age of epilepsy onset, more frequent seizures, longer duration of epilepsy, high number of relatives with epilepsy and long-term antiepileptic drugs therapy. Psychiatric manifestations may include both positive and negative symptoms, including auditory hallucinations, paranoid delusions, and disorganized thought and/or behaviour. Poor adherence to treatment with oral antipsychotics occurs in more than 40% of patients; long-acting injectable medication should be considered, bearing in mind interactions with anti-epileptic medication and possibility of increased side effects. Conclusions Our findings emphasize the importance of early recognition and management of psychosis in epileptic patients. Unfortunately, there is lack of evidence for the use of antipsychotic medication in epileptic patients, since available studies pertain to populations with primary psychiatric disorders.

Abstract
Introduction Starting in December 2019, the coronavirus SARS-CoV-2 emerged and soon acquired a pandemic dimension. The evidence that 1 in 3 patients presented neuropsychiatric symptoms highlighted SARS-CoV-2 neurotropic properties. The involvement of the Central Nervous System (CNS) seems to be associated with poor prognosis, and it can occur independently of the respiratory system. Objectives To assess neuropsychiatric symptoms in SARS-CoV-2 patients and possible mechanisms of CNS invasion; to reflect on what changes should be made in order to avoid short and long-term complications. Methods A non-systematic literature review was performed, including publications between January and August 2020. Results The most frequent CNS presentations included fatigue (38-75%), headache (6,5-34%), nausea or vomiting (1-13,7%). Regarding PNS involvement, three kinds of hypoesthesia (hyposmia, hypogeusia, and hypopsia) were commonly present. Additionally, cases of neurological syndromes associated with SARS-CoV2 were reported, being related to a poor prognosis in cases such as brainstem infiltration. Another major concern regarding CNS involvement is the possibility of permanent neurological disabilities. Importantly there are reports of patients who tested positive for SARS-CoV-2 in CFS, without samples from nasopharyngeal swabs. Different hypothesis are postulated to explain possible mechanisms through which SARS-CoV-2 affects CNS, including: direct invasion through the olfactory nerve, hematogenous route through ACE-2 (angiotensin-converting enzyme) receptor expressed in blood-brain-barrier; or indirect mechanisms. Conclusions Here we discuss the neuropsychiatric manifestations of SARS-CoV-2 infection and the potential mechanisms by which they occur at an early stage. Awareness, prevention and early treatment of potential neuropsychiatric symptoms of COVID-19 should not be overlooked, especially because they seem to predict a worse prognosis.

Abstract
Introduction Prenatal alcohol exposure can have a negative impact on a child’s neurocognitive development. Still, about 16% of European women maintain alcohol consumption, even after knowing they are pregnant. Several studies have shown that alcohol use patterns alter drastically during pregnancy. However, little is known about how these change in women with Alcohol Use Disorder (AUD) diagnosis. Objectives To understand the impact of pregnancy on alcohol use patterns in women at high risk or with previous AUD diagnosis. Methods Bibliographic research was made through the PubMed/NCBI database. No time limit was specified on the search. Pertinent manuscripts were individually reviewed for additional relevant citations. Results Several factors influence alcohol consumption during pregnancy, including financial status, educational level, and high levels of psychological stress. Although older age at the onset of pregnancy is deemed a risk factor for alcohol consumption, women of 25 or fewer years of age are at higher risk for AUD, as are those with a history of criminal behaviour and family history of AUD. Pregnancy seems to play a critical role in altering alcohol use patterns, reducing the risk of AUD in about 70%, regardless of pregnancy trimester. This is seen even in women who present high-risk factors for AUD. Conclusions Pregnancy presents itself as a behavioural change promoter and should be regarded as a window of opportunity for intervention in women with AUD. However, there are few studies that focus on alcohol consumption patterns specifically in women with AUD, whereby making it necessary to extrapolate the available data.

Abstract
IntroductionThe relationship between alcohol use and dementia is complex. There is a J-shaped relationship between alcohol use and cognitive impairment and evidence shows that one-quarter of the dementia population have alcohol related problems. It is estimated that alcohol-related dementia (ARD) contributes for about 10% of all cases of dementia, especially early-onset dementia, but is largely overlooked or seen as a comorbid factor.ObjectivesTo clarify the relationship between alcohol use, alcohol-related brain damage and dementia; to review the clinical features, neuropathology, nosology and neuropsychology of ARD and alcohol-induced persisting amnestic syndrome (Wernicke-Korsakoff syndrome- WKS).MethodsWe performed a review of systematic reviews from the last 10 years. A total of 28 systematic reviews were identified.ResultsHeavy alcohol use has been shown to be a contributory factor and necessary factor in the development of multiple brain diseases. It may cause brain damage in multiple ways: direct neurotoxic effect of acetaldehyde; thiamine deficiency. It is also a risk factor for other conditions, such as hepatic encephalopathy, epilepsy and head injury.ConclusionsClinical observation favors the diagnosis of ADR as a distinct entity, but broader evidence reflects significant commonality between ARD and WKS, tough neuropsychological studies have largely attempted to differentiate these syndromes. Repeated episodes of WKS may cause cognitive deterioration. In contrast to other common causes of dementia, the decline in cognitive functioning in ARD is relatively non-progressive if abstinence is maintained, or even partially reversible, as supported by neuroimaging evidence. Given the increase in per capita consumption, it is expected a disproportionate increase in ARD.

Abstract
Introduction The analysis of the impact of individuals’ behaviors on their health involves several variables, namely alcoholism. It is necessary to take in account that when anxiety is excessive it may be very disabling and produce many adverse effects, such as unsatisfactory work performance, anxiety disorders, depressive mood and somatic symptoms. These elements affect the Quality of Life (QOL) drastically, while social support of the patients protect QOL. Objectives To assess the quality of life of patients with alcohol use disorders in treatment for alcohol use disorder (AUD). Methods An exploratory, descriptive and correlational study was carried out. A sociodemographic scale was used, an instrument constructed by the authors that assesses the existence of risk behaviors and protective health behaviors, the Social Support Satisfaction Scale (ESSS), and a quality of life assessment scale (WHOQOL-Bref). Data analysis was performed using IBM SPSS 25 statistics. Results Sample consisting of 34 patients with Alcohol Use Disorders. Abstinence time is positively correlated with QOL and negatively correlated with social support satisfaction. Conclusions This study shows that in treatment of patients with AUD, longer abstinence times have a positive effect on QOL and overall wellbeing of patients, while being associated with a lower satisfaction with social support. Treatment Units dedicated to AUD should keep striving for maintenance of abstinence due to these positive effects.

Abstract
IntroductionThe current SARS-CoV-2 pandemic has many implications, one of them being alcohol consumption. The impact of long-term distancing measures in terms of alcohol use and misuse is yet unknown. Any increase, would not only add to the usual disease burden associated with alcohol, but also add to the COVID-19 load, given that alcohol use may weaken the immune response.ObjectivesTo characterize and compare the pattern of alcohol consumption throughout the pandemic in patients with the diagnosis of Alcohol Use Disorder; to identify factors considered as most relevant in the increase of alcohol consumption.MethodsWe conducted a observational study in an outpatient population in Centro Hospitalar Psiquiátrico de Lisboa (Portugal) with diagnosis of Alcohol Use Disorder, 6 months after the pandemic lockdown. We characterized our sample regarding social, demographic and clinical categories. We applied auto-filled questionnaires, particularly: Mental Health Inventory (MHI), Positive Mental Health Scale (PMHS) and Severity of Alcohol Dependence Questionnaire (SADQ-C).ResultsA total of 65 patients were included. More than 30% changed their drinking habits because of the pandemic. Nearly half of these increased consumption, and half decreased (16% vs 14%). The increase affected particularly men, and was related with the severity of alcohol dependence, stress-related coping strategies and psycopathology; on the other hand, a lowered level of consumption based on the decrease of alcohol accessability and affordability.ConclusionsThe current situation is unique in terms of mass physical distancing and may trigger different behaviours that should be monitored. Governments should give public health warning about excessive alcohol consumption to protect vulnerable individuals.DisclosureNo significant relationships.

Abstract
LIDAR sensors are one of the key enabling technologies for the wide acceptance of autonomous driving implementations. Target identification is a requisite in image processing, informing decision making in complex scenarios. The polarization from the backscattered signal provides an unambiguous signature for common metallic car paints and can serve as one-point measurement for target classification. This provides additional redundant information for sensor fusion and greatly alleviates hardware requirements for intensive morphological image processing. Industry decision makers should consider polarization-coded LIDAR implementations. Governmental policy makers should consider maximizing the potential for polarization-coded material classification by enforcing appropriate regulatory legislation. Both initiatives will contribute to faster (safer, cheaper, and more widely available) advanced driver-assistance systems and autonomous functions. Polarization-coded material classification in automotive applications stems from the characteristic signature of the source of LIDAR backscattering: specular components preserve the degree of polarization while diffuse contributions are predominantly depolarizing.

Abstract
We investigate the relaxation dynamics of protein-polymer conjugates by neutron scattering spectroscopy to understand to which extent the coating of a protein by a polymer can replace water in promoting thermal structural fluctuations. For this purpose, we compare the dynamics of protein-polymer mixtures to that of conjugates with a variable number of polymers covalently attached to the protein. Results show that the flexibility of the protein is larger in protein-polymer mixtures than in native protein or in conjugates, even in the dry state. Upon hydration, both the native protein and the conjugate show equivalent dynamics, suggesting that the polymer grafted on the protein surface adsorbs all water molecules.

Abstract
The evaluation of conservative treatments' efficacy on natural building stones are usually based on standard recommendation routines finalized to evaluate compatibility and harmfulness of products in turn of the substrate. However, the visualization and the quantification of products inside pore structure of natural stones is not immediate through standard tests, so that imaging and advanced techniques are recently proposed in material conservation field to improve knowledge on penetration depth, modification of pore-air interface at different scale and monitor dynamic absorption processes. Moreover, natural stones are usually characterized by complex structure, which changes due to conservative treatments have to be inspected at different scale (from micrometer to nanometer). In this prospective, the assessment of laboratory practices able to integrate multiscale methods and give back a complete overview on interaction between new conservative formulates and natural stones is of high interest. In this paper, we propose a methodological routine for efficacy assessment of conservative products, incorporating classical and innovative nondestructive techniques. Validation of the workflow has been verified on a high porous natural stone treated with new hybrid formulates appropriately customized for conservation issues. •The study intends to add new insights on problems related to consolidation of high porous carbonate stone, application methods in consolidating natural stones and methods to evaluate efficacy of new products.•A multi-scale laboratory investigation procedure is proposed by integrating standard and innovative nondestructive methods. Merits and limits of each applied method are discussed during validation.•The possibility to incorporate standard routines and/or substitute destructive testing with non-destructive ones seem to be a valid alternative to evaluate efficiency and monitor behavior of stones treated with consolidating products.

Abstract
IntroductionAlcohol use disorders (AUD) is a preventable cause of significant morbidity and mortality worldwide. AUD is a heterogeneous disorder stemming from a complex interaction of neurobiological, genetic, and environmental factors. To achieve treatment effectiveness this heterogenity should be considered, as well as safety.ObjectivesReview mechanisms underlying alcohol addiction in order to work out new, more effective treatment strategies.AimTo update on treatment for alcoholism.MethodsA literature search was performed on PubMed database.ResultsAlcohol dependence is a chronic, relapsing condition in which there is evidence of significant change in the motivation and control systems in the brain. Increasingly drug therapy is focused not just on the treatment of the acute withdrawal syndrome, but on modifying these other dysregulated brain systems. Of the numerous neurotransmitter systems that have been identified for the development of new medicines, the most promising compounds appear to be those that modulate the function of opioids, glutamate with or without gamma-aminobutyric acid, and serotonin. Other putative therapeutic medications including direct modulators of dopamine function and enzyme inhibitors also shall be discussed. At present, only four medications are approved for the treatment of alcohol dependence in Europe, that is naltrexone, acamprosate, disulfiram and the most recent nalmefene. Among other promising strategies the following drugs are mentioned: baclofen, topiramate, ondansetron, aripiprazole, rimonabant and varenicline.ConclusionsPharmacological development remains a high priority in the alcoholism field. Drugs have different safety profiles that need to be balanced with the treatment objective, individual patient preferences and comorbid conditions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The concept of zoonotic hepatitis E in industrialized countries has emerged with the discovery of swine strains of hepatitis E virus (HEV) genotype 3, closely related to human HEV. Different routes of zoonotic HEV transmission have been recognized, including contact with infected pigs. Workers occupationally exposed to swine (WOES) have been considered a risk group for HEV infection, but contradictory results have been reported. In the present study, we searched for anti-HEV IgG in WOES (butchers, slaughterhouse workers, veterinarians and pig farmers; n = 114) and in the general population (n = 804) in order to investigate the potential occupational risk of zoonotic HEV infection in this work group. A significantly higher (p = 0.008) anti-HEV IgG seroprevalence was found in WOES (30.7 %) when compared with the general population (19.9 %). Multivariate analysis showed that having professions with exposure to pigs for more than 16.5 years was a risk factor for being positive for anti-HEV IgG (aOR of 5.4, 95 % CI 1.9-15.6, p = 0.002). To our knowledge, this is the first study on the prevalence of anti-HEV IgG in WOES in Portugal, also showing increased probability for infection in this group.

Abstract
IntroductionOver the past 40 years, services for psychiatric patients have become increasingly deinstitutionalized, shifting away from inpatient facilities. as a result, patients seek other avenues for treatment, including outpatient facilities and community resources. Unfortunately, those resources have also become increasingly constrained by widespread budget cuts, leaving patients with the health care system's last remaining safety net—the emergency department (ED).Because EDs are seeing increasing numbers of patients, hospital administrators have recognized the importance of improving throughput and the quality of care delivered in EDs.The aim of this report is to investigate the gender difference among patient's profile in psychiatric emergency room, assessing the socio-demographic and clinical characteristics, reasons for attendance and practices.MethodsRetrospective and observational study, conducted at Centro Hospitalar e Universitário de Coimbra, during a three month period. Statistical analysis of data with “SPSS 21”.ResultsDuring the three months period, a total of 2309 patients were admitted in Psychiatric ED, 1485 female and 824 male.Regarding clinical data, the authors are expecting to find different psychopathology among male and female, as well as psychiatric comorbidities, diagnoses after discharge, treatment conducts, social support and different rates of psychiatric comorbidities.ConclusionsFactors such as patient's vulnerability, defined by socio-demographic elements, characteristic as the type and severity of their mental illness, social support, treatment adherence, with significant implications of prognosis, costs and care. The conducted study enabled us to outline a profile of male and female psychiatric patients in ED.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionAlcohol dependence is one of the psychiatric disorders for which hereditary influence is strongest. In fact, the importance of genetic factors in transmission of vulnerability to alcohol dependence was first described in literature many years ago by psychiatrists who dedicate to its study. That vulnerability may be explained by an epigenetic model in which biological hereditary factors associate with environmental factors to cause alcohol dependence.ObjectivesStudy the influence of genetic factors on alcohol dependence.MethodsDuring 4 consecutive months a sample of alcoholic patients was collected from the Alcohol Treatment Unit of CHPL (inpatients and outpatients). Biographic data, patient's psychiatric diagnosis and family history of alcohol dependence or of dependence of other drugs were recorded.ResultsInitial sample included 122 patients. After exclusion of patients who were also hospitalized in that period, the final sample included 102 patients (26% female), with a mean age of 48 years old. Main patients’ diagnosis was alcohol dependence but most of them (52%) presented psychiatric comorbidity. Most patients (55%) had family history of alcohol dependence or dependence of other substances, 26% did not have and 19% did not know. For 61% of patients, the father and/or mother were the affected relative. Most patients (61%) who had a family history of alcohol dependence or dependence of other substances had 2 or more affected relatives.ConclusionsMost patients with alcohol dependence have family history of alcohol dependence or dependence of other substances, usually in more than 1 relative, which must be taken in account during treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
After reviewing the protocol-dependent properties of HDA, which thermally anneals to LDA, and the data gap over an unusually large T-range between HDA, LDA, and water, we investigate whether or not, despite HDA's ill-defined state and distinction from a glass, the HDL-LDL fluctuations view of the two-liquid model can explain water's anomalous behavior. An analysis of the density, ρ, compressibility, β, heat capacity, Cp, and thermal conductivity, κ, of water over a monotonic (continuous) path bridging this data gap shows the following: (i) Such a path between ρwater at 320 K and ρHDA yields an untenable thermal expansion coefficient of water. (ii) There is neither a continuous path between βwater at 353 K and βHDA, nor between Cp,water at 363 K and Cp,HDA. (iii) The same value of ρwater, of βwater, or of Cp,water at two temperatures separated by a maxima or a minima is incompatible with the HDL-LDL fluctuations view. (iv) κLDA at ∼140 K is about twice that of κ water at 253 K. (v) κHDA at 120 K is incompatible with κwater at T > 320 K. Thus, there is an internal inconsistency between the thermodynamics of HDA seen as a glass and that of water seen as an HDL-LDL mixture, which is incompatible with both the HDL-LDL fluctuations view and the liquid-liquid transition.

Abstract
Using the Dürrer electrode needle to record the intramural electrogram and a standard peripheral electrocardiogram (ECG) lead as reference, the authors studied the action of 9 different drugs in the conduction system of dogs. The authors concluded that diphenylhydantoin and lignocaine would be useful in dysrhythmias related to increased excitability and perhaps increased automatism. Ajmaline and quinidine may be some of some interest in dysrhythmias due to conduction disturbances; and, finally, ajmaline, diphenylhydantoin, di-isopyramide and quinidine may be useful in dysrhythmias due to focal re-entry.

Abstract
Alzheimer's disease (AD) has become a health problem to societies worldwide affecting millions of people. AD normally ensues in middle and late life but its specific cause remains unknown. Besides amyloid-β deposition and hyperphosphorylated tau protein, increased production of reactive species (RS) has also been described to be a hallmark in early steps of this disorder. Antioxidant therapy has received considerable attention over the last years as a promising approach to delay or slow the neurodegeneration progression in AD either by boosting the pool of endogenous antioxidants (e.g.vitamins, coenzyme Q10 or melatonin) or by the intake of dietary antioxidants, such as phenolic compounds of flavonoid or non-flavonoid type. However, the majority of antioxidants studied so far have limited success in clinical trials, a fact that could be related to their poor distribution and with the inherent difficulties to cross the blood brain barrier and attain the target sites. Despite the evidence that different classes of antioxidants are neuroprotectants in vitro, the clinical data is not consistent. Alzheimer's disease and antioxidant therapy is still an open question: the research is far from the end but the success may not be so time-consuming if the data obtained so far are gathered and rationally analyzed either by checking new targets or by the obtention of new and effective compounds, for instance by the rational modification of the previous ones.
