Perturbações da personalidade nos cuidados primários
A perturbação da personalidade é uma alteração da personalidade e comportamentos de um individuo que diferem dos comummente aceites na sociedade, onde este se insere. Estas perturbações têm um impacto negativo no funcionamento e na vida do indivíduo, contribuindo para o seu sofrimento. Interferindo determinantemente na construção de relações. Surge frequentemente durante a adolescência mantendo-se estável ao longo do tempo. Estudos prévios indicam uma prevalência das perturbações entre 4-15% da população geral, aumentando para aproximadamente 25% na amostra dos utentes dos cuidados de saúde primários. Apesar destes valores, os médicos continuam a apresentar dificuldades em diagnosticar e lidar com estes doentes, impedindo que os doentes recebam uma intervenção direcionada e adaptada à problemática vivenciada. É nesse contexto que surge este trabalho, tendo como principal objetivo identificar as principais necessidades que os médicos de Medicina Geral de Familiar (MMGF) têm ao lidar com este grupo de doentes e determinar o seu grau de sensibilização para a temática. Pretende-se, ainda, compreender as barreiras que os doentes possam enfrentar, na perspetiva do profissional de saúde. Para tal, foram realizadas entrevistas semiestruturadas e questionários a 24 MMGF da área de Lisboa e Vale do Tejo. A análise dos dados foi realizada através do método “thematic analysis” e a análise estatística através de SPSS. As principais dificuldades apuradas foram a baixa sensibilização para as perturbações da personalidade, a realização do diagnóstico, a gestão destes doentes, principalmente para criar uma boa relação médico-doente e na terapêutica. Já as principais necessidades apuradas foram a formação e a proximidade com a Psiquiatria e Psicologia. Por fim, os médicos identificaram como principais barreiras dos doentes a falta de insight e os problemas socioeconómicos. Foi possível concluir que a sensibilização e a formação dos MMGF é um dos primeiros passos para ajudar os MMGF a lidar com estes doentes.

Multistage antiplasmodium activity of astemizole analogues and inhibition of hemozoin formation as a contributor to their mode of action
A drug repositioning approach was leveraged to derivatize astemizole (AST), an antihistamine drug whose antimalarial activity was previously identified in a high-throughput screen. The multistage activity potential against the Plasmodium parasite's life cycle of the subsequent analogues was examined by evaluating against the parasite asexual blood, liver, and sexual gametocytic stages. In addition, the previously reported contribution of heme detoxification to the compound's mode of action was interrogated. Ten of the 17 derivatives showed half-maximal inhibitory concentrations (IC50s) of <0.1 μM against the chloroquine (CQ)-sensitive Plasmodium falciparum NF54 ( PfNF54) strain while maintaining submicromolar potency against the multidrug-resistant strain, PfK1, with most showing low likelihood of cross-resistance with CQ. Selected analogues ( PfNF54-IC50 < 0.1 μM) were tested for cytotoxicity on Chinese hamster ovarian (CHO) cells and found to be highly selective (selectivity index > 100). Screening of AST and its analogues against gametocytes revealed their moderate activity (IC50: 1-5 μM) against late stage P. falciparum gametocytes, while the evaluation of activity against P. berghei liver stages identified one compound (3) with 3-fold greater activity than the parent AST compound. Mechanistic studies showed a strong correlation between in vitro inhibition of β-hematin formation by the AST derivatives and their antiplasmodium IC50s. Analyses of intracellular inhibition of hemozoin formation within the parasite further yielded signatures attributable to a possible perturbation of the heme detoxification machinery.

Disfunção miccional após cirurgia de incontinência urinária com colocação de sling de uretra média (TVT-O™/TVT-Abbrevo®) em mulheres com bexiga hipoativa versus bexiga normocontrátil
Objetivo: Este estudo pretende comparar o risco de disfunção miccional após cirurgia de incontinência urinária com colocação de sling da uretra média em mulheres com bexiga hipoativa versus bexiga normocontrátil. Material e Métodos: Estudo observacional retrospetivo que incluiu mulheres com incontinência urinária de esforço ou mista, submetidas a correção cirúrgica com sling da uretra média no serviço de Ginecologia do Hospital de Santa Maria, entre 2004 e 2018. Foram excluídas doentes com prolapso de órgão pélvico de grau superior ou igual a 3, cirurgia pélvica/sagrada prévia, ou uropatia obstrutiva baixa. Com base no exame urodinâmico pré-operatório, foram divididas no grupo em estudo (bexiga hipoativa) e no grupo de controlo (bexiga normocontrátil). Avaliaram-se os dados das consultas dos 6, 12, 24 e 48 meses após cirurgia. A presença de sintomas do trato urinário inferior e/ou agravamento de urgência miccional foram utilizados como indicadores de disfunção miccional. O teste da tosse negativo foi utilizado como definição de cura objetiva. Os desfechos subjetivos foram avaliados utilizando o King’s Health Questionnaire. Registaram-se as complicações peri-operatórias. Resultados: Das 110 mulheres analisadas, 89 apresentavam bexiga normocontrátil e 21 bexiga hipoativa. Não se observaram diferenças entre os dois grupos quanto à taxa de disfunção miccional em cada consulta de seguimento. No grupo de controlo observou-se um aumento (p=0,011) da disfunção miccional ao longo das consultas, sobretudo entre as consultas dos 6 e 12 meses e a dos 48 meses (48,3% vs 34,10%; p=0,039; 48,3% vs 33,70%; p=0,017). O grupo em estudo apresentou uma maior taxa de cura subjetiva (94,70% vs 71,40%; p= 0,038) e uma pontuação de KHQ inferior (23,00 vs 25,50; p=0,013). Não foram registadas diferenças quanto às complicações pós-operatórias. Conclusão: Doentes com bexiga hipoativa não aparentam desenvolver maior taxa de disfunção miccional que as doentes com bexiga normocontrátil após cirurgia com slings da uretra média.

Neuroimaging in functional movement disorders
Purpose of review: Functional movement disorders are common and disabling causes of abnormal movement control. Here, we review the current state of the evidence on the use of neuroimaging in Functional movement disorders, particularly its role in helping to unravel the pathophysiology of this enigmatic condition. Recent findings: In recent years, there has been a shift in thinking about functional movement disorder, away from a focus on high-level psychological precipitants as in Freudian conversion theories, or even an implicit belief they are 'put-on' for secondary gain. New research has emphasised novel neurobiological models incorporating emotional processing, self-representation and agency. Neuroimaging has provided new insights into functional movement disorders, supporting emerging neurobiological theories implicating dysfunctional emotional processing, self-image and sense of agency. Recent studies have also found subtle structural brain changes in patients with functional disorders, arguing against a strict functional/structural dichotomy.

Control of Carbapenem-resistant Enterobacteriaceae, Acinetobacter baumannii, and Pseudomonas aeruginosa in healthcare facilities: a systematic review and reanalysis of quasi-experimental studies
Carbapenem-resistant Enterobacteriaceae (CRE), Acinetobacter baumannii (CRAB), and Pseudomonas aeruginosa (CRPsA) are a serious cause of healthcare-associated infections, although the evidence for their control remains uncertain. We conducted a systematic review and reanalysis to assess infection prevention and control (IPC) interventions on CRE-CRAB-CRPsA in inpatient healthcare facilities to inform World Health Organization guidelines. Six major databases and conference abstracts were searched. Before-and-after studies were reanalyzed as interrupted time series if possible. Effective practice and organization of care (EPOC) quality criteria were used. Seventy-six studies were identified, of which 17 (22%) were EPOC-compatible and interrupted time series analyses, assessing CRE (n = 11; 65%), CRAB (n = 5; 29%) and CRPsA (n = 3; 18%). IPC measures were often implemented using a multimodal approach (CRE: 10/11; CRAB: 4/5; CRPsA: 3/3). Among all CRE-CRAB-CRPsA EPOC studies, the most frequent intervention components included contact precautions (90%), active surveillance cultures (80%), monitoring, audit and feedback of measures (80%), patient isolation or cohorting (70%), hand hygiene (50%), and environmental cleaning (40%); nearly all studies with these interventions reported a significant reduction in slope and/or level. The quality of EPOC studies was very low to low.

New insights into the role of epithelial–mesenchymal transition during aging
Epithelial⁻mesenchymal transition (EMT) is a cellular process by which differentiated epithelial cells undergo a phenotypic conversion to a mesenchymal nature. The EMT has been increasingly recognized as an essential process for tissue fibrogenesis during disease and normal aging. Higher levels of EMT proteins in aged tissues support the involvement of EMT as a possible cause and/or consequence of the aging process. Here, we will highlight the existing understanding of EMT supporting the phenotypical alterations that occur during normal aging or pathogenesis, covering the impact of EMT deregulation in tissue homeostasis and stem cell function.

Burnout and dropout intention in medical students : the protective role of student engagement
Introdução: O Burnout no estudante refere-se ao exceder dos recursos emocionais devido à exigência do estudo, cinismo e desempenho acadêmico reduzido. As consequências são relevantes, pelo que os fatores de risco e proteção do burnout não devem ser negligenciados. Há poucos estudos sobre as variáveis psicológicas e influência no burnout em estudantes de medicina em Portugal. Foi desenhado um modelo estrutural para estimar os efeitos das estratégias de coping, satisfação com o suporte social, distress geral, no envolvimento académico, burnout do aluno e intenção de abandono do curso, numa amostra de estudantes de medicina portugueses, com a intenção de planear intervenções futuras para prevenir o Burnout. Métodos: Neste estudo transversal, a amostra foi composta por 532 alunos, matriculados no 1.º e 2.º ano do Mestrado Integrado em Medicina da Faculdade de Medicina da Universidade de Lisboa em 2020. Os dados foram recolhidos através de instrumentos psicométricos de autorrelato online (Maslach Burnout Inventory - Student Survey, Social Support Satisfaction Scale for College Students, Brief COPE Scale for College Students, University Student Engagement Inventory, e Depression, Ansiety and Stress Scale) juntamente com variáveis sociodemográficas e académicas. Os dados foram analisados por meio de modelos de equações estruturais (análise fatorial confirmatória e modelo estrutural latente). Resultados: O modelo estrutural das variáveis latentes apresentou um bom ajuste aos dados e confirmou que em relação à intenção de abandono, o efeito da satisfação com o suporte social e coping adaptativo é negativo, enquanto o efeito do coping desadaptativo, depressão, stress e ansiedade é positivo. Conclusão: A satisfação com suporte o social, o distress geral, o coping adaptativo e mal-adaptativo são preditores de burnout do aluno, que por sua vez, prediz a intenção de abandono. O envolvimento académico atua como um protetor das intenções de abandono e atenua o efeito do burnout na intenção de abandono.
Metallosis: a new form of autoimmune/autoinflammatory syndrome induced by adjuvants syndrome (ASIA)?
Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) is a new entity in which exposure to an adjuvant triggers an aberrant autoimmune response. Metallosis is a rare condition characterized by the deposition and build-up of metal debris in the soft tissues of the body associated with metal-on-metal (MOM) prosthetic devices. It can present with local/systemic symptoms and signs due to a chronic inflammatory host response. The authors present the case of a 51-year-old woman with a 6-month history of systemic complaints due to intoxication with metal ions from hip metallosis. This case highlights the importance of follow-up and continuous monitoring of patients with a hip prosthesis. As this is a rare condition, a patient presenting with unspecific symptoms such as ASIA syndrome induced by metallosis requires a high level of clinical suspicion as the removal of the adjuvant can resolve the condition. Learning points: Asia syndrome is a new entity in which exposure to an adjuvant triggers an aberrant autoimmune response.Metallosis is an uncommon condition with local and systemic presentation.A high level of suspicion and close monitoring is needed in patients with vague systemic complaints.

Neurological complications of cardiac tumors
Purpose of review: This article reviews recent literature regarding the neurological manifestations of cardiac tumors, including diagnosis, pathophysiology, and treatment. Recent findings: Clinical cases of patients with acute ischemic stroke due to cardiac tumors who were treated with intravenous alteplase show a favorable safety profile. Mechanical thrombectomy seems to be a reasonable treatment alternative for these patients, when there is a large vessel occlusion. Histopathology analysis of mechanical thrombectomy specimens may allow the diagnosis of a cardiac tumor. Prolonged time interval between stroke and tumor excision surgery is significantly associated with stroke recurrence. Myxomatous aneurysms are a late complication of cardiac myxomas, which commonly demand imaging follow-up after excision of the primary tumor. Aneurysms are more frequent in patients who present with other embolic complications. Conservative treatment of myxomatous aneurysms is a reasonable strategy, as the majority of aneurysms remain stable over many years. Spontaneous regression of these formations has been documented after excision of the primary tumor. Other complications recently described include acute psychosis and mononeuropathy multiplex. Cardiac tumors are rare. There are mainly case reports and retrospective case series describing the neurological manifestations of cardiac tumors. Hyperacute stroke treatment seems to be safe, and mechanical thrombectomy is a reasonable treatment. A conservative approach towards myxomatous aneurysms should be considered.

Regulation of ATR activity via the RNA polymerase II associated factors CDC73 and PNUTS-PP1
Ataxia telangiectasia mutated and Rad3-related (ATR) kinase is a key factor activated by DNA damage and replication stress. An alternative pathway for ATR activation has been proposed to occur via stalled RNA polymerase II (RNAPII). However, how RNAPII might signal to activate ATR remains unknown. Here, we show that ATR signaling is increased after depletion of the RNAPII phosphatase PNUTS-PP1, which dephosphorylates RNAPII in its carboxy-terminal domain (CTD). High ATR signaling was observed in the absence and presence of ionizing radiation, replication stress and even in G1, but did not correlate with DNA damage or RPA chromatin loading. R-loops were enhanced, but overexpression of EGFP-RNaseH1 only slightly reduced ATR signaling after PNUTS depletion. However, CDC73, which interacted with RNAPII in a phospho-CTD dependent manner, was required for the high ATR signaling, R-loop formation and for activation of the endogenous G2 checkpoint after depletion of PNUTS. In addition, ATR, RNAPII and CDC73 co-immunoprecipitated. Our results suggest a novel pathway involving RNAPII, CDC73 and PNUTS-PP1 in ATR signaling and give new insight into the diverse functions of ATR.

SVC Is a marker of respiratory decline function, similar to FVC, in patients with ALS
Introduction: Respiratory function is a critical predictor of survival in amyotrophic lateral sclerosis (ALS). We aimed to determine if slow vital capacity (SVC) is a predictor of functional loss in ALS as compared to forced vital capacity (FVC). Methods: Consecutive ALS patients in whom respiratory tests were performed at baseline and 6 months later were included. All patients were evaluated with revised ALS functional rating scale (ALSFRS-R) and the respiratory tests, SVC, and FVC. Significant independent variables of functional decay were assessed by univariate Kaplan-Meier log-rank test and multivariate Cox proportional hazards model. A monthly decay not exceeding 0.92 in ALSFRS was considered as the time event. Results: We included 232 patients (134 men; mean onset-age 59.1 ± 11.23 years; mean disease duration from first symptoms to first visit: 14.5 ± 12.9 months; 166 spinal and 66 bulbar onset). All variables studied declined significantly between the two evaluations (p < 0.001). FVC and SVC were strongly correlated at study entry (r 2 = 0.98, p < 0.001) and FVC and SVC decays between first evaluation and 6 months after were the only significant prognostic variables of functional decay (p < 0.001). Conclusion: FVC and SVC decay are inter-changeable in predicting functional decay in ALS. Pharmacological interventions reducing the decline rate of FVC and SVC can have a positive impact on the global functional impairment, with relevant implications for clinical trials' design and interpretation.

Impacto da pandemia COVID-19 na saúde mental dos profissionais de saúde
A presente revisão tem como objetivo estudar o impacto da pandemia COVID-19 na saúde mental dos profissionais de saúde, com particular atenção para a associação entre a depressão, ansiedade e burnout nos profissionais de saúde e a pandemia COVID-19. A metodologia utilizada foi a de uma revisão não sistemática da literatura, tendo sido realizada uma pesquisa com os termos “COVID-19”, “anxiety”, “depression”, “burnout”, “mental health” e “healthcare workers”, na PubMed e na Cochrane. Os resultados indicam que os profissionais de saúde, antes do início da pandemia COVID-19, apresentavam uma maior prevalência de depressão, ansiedade e burnout comparativamente à população em geral. Durante a pandemia, observou-se um aumento da prevalência das patologias referidas acima, especialmente em profissionais de saúde com contacto direto com doentes com COVID-19. Foram ainda identificadas várias estratégias, que têm sido sugeridas e implementadas, de modo a diminuir o impacto da pandemia na saúde mental dos profissionais de saúde, apesar da escassa evidência científica disponível acerca da sua eficácia. Assim, é essencial a realização de estudos adicionais sobre o tema de modo a controlar fatores de risco e desenvolver estratégias, passíveis de serem adotadas pelas organizações de saúde, para diminuir os níveis de burnout, ansiedade e depressão, garantindo que os profissionais de saúde se encontram nas melhores condições para combater a pandemia COVID-19.

European postgraduate curriculum in geriatric medicine developed using an international modified Delphi technique
Background: the European Union of Medical Specialists (UEMS-GMS) recommendations for training in Geriatric Medicine were published in 1993. The practice of Geriatric Medicine has developed considerably since then and it has therefore become necessary to update these recommendations. Methods: under the auspices of the UEMS-GMS, the European Geriatric Medicine Society (EuGMS) and the European Academy of Medicine of Ageing (EAMA), a group of experts, representing all member states of the respective bodies developed a new framework for education and training of specialists in Geriatric Medicine using a modified Delphi technique. Thirty-two expert panel members from 30 different countries participated in the process comprising three Delphi rounds for consensus. The process was led by five facilitators. Results: the final recommendations include four different domains: 'General Considerations' on the structure and aim of the syllabus as well as quality indicators for training (6 sub-items), 'Knowledge in patient care' (36 sub-items), 'Additional Skills and Attitude required for a Geriatrician' (9 sub-items) and a domain on 'Assessment of postgraduate education: which items are important for the transnational comparison process' (1 item). Conclusion: the current publication describes the development of the new recommendations endorsed by UEMS-GMS, EuGMS and EAMA as minimum training requirements to become a geriatrician at specialist level in EU member states.

Time, age and season effect on thyroid function
Introdução: As hormonas tiroideias têm um papel importante na manutenção da temperature corporal enquanto ocorrem variações da temperatura ambiente. Tanto a idade como a estação do ano podem infulenciar a função e autoimunidade tiroideias. Objectivos: Explorar os efeitos da idade, tempo de evolução da doença e estação do ano na função e autoimunidade tiroideias. Doentes e Métodos: Análise retrospetiva da base de dados da consulta externa de endocrinologia de um hospital central público. Foram selecionados doentes com tiroidite de Hashimoto (HT) e Bócio Nodular Simples (SNG) sem tratamento com hormonas tiroideias e com análises laboratoriais colhidas no verão ou inverno. A análise estatística foi realizada para detetar diferenças na função e autoimunidade tiroideias ao longo do tempo e entre estações do ano. Resultados: Verificou-se uma redução significativa dos níveis de T4 em doentes com SNG e dos níveis de T4, T3 e TPOAb em doentes com HT, ao longo do tempo. Não foram encontradas diferenças estatisticamente significativas na função e autoimunidade tiroideias quando comparadas avaliações do verão e inverno. No entanto, há uma tendência estatística para a redução de T4, FT4 e TgAb no verão. Foi observada uma redução estatisticamente significativa dos níveis de T4 do inverno para o verão. Conclusão: A idade/tempo parece ser um fator relevante na função tiroideia com uma redução dos níveis de T4 em doentes com SNG e redução dos níveis de T3 e T4 em doentes com HT, sendo que estas alterações não causam disfunção tiroideia. Uma redução da função e autoimunidade tioirdeia é sugerida pela tendência estatística para a redução dos níveis de T4, FT4 e TgAb no verão e redução estatisticamente significativa dos níveis de T4 observada do inverno para o verão.
Spatiotemporal analysis for detection of pre-symptomatic shape changes in neurodegenerative diseases: initial application to the GENFI cohort
Brain atrophy as measured from structural MR images, is one of the primary imaging biomarkers used to track neurodegenerative disease progression. In diseases such as frontotemporal dementia or Alzheimer's disease, atrophy can be observed in key brain structures years before any clinical symptoms are present. Atrophy is most commonly captured as volume change of key structures and the shape changes of these structures are typically not analysed despite being potentially more sensitive than summary volume statistics over the entire structure. In this paper we propose a spatiotemporal analysis pipeline based on Large Diffeomorphic Deformation Metric Mapping (LDDMM) to detect shape changes from volumetric MRI scans. We applied our framework to a cohort of individuals with genetic variants of frontotemporal dementia and healthy controls from the Genetic FTD Initiative (GENFI) study. Our method, take full advantage of the LDDMM framework, and relies on the creation of a population specific average spatiotemporal trajectory of a relevant brain structure of interest, the thalamus in our case. The residuals from each patient data to the average spatiotemporal trajectory are then clustered and studied to assess when presymptomatic mutation carriers differ from healthy control subjects. We found statistical differences in shape in the anterior region of the thalamus at least five years before the mutation carrier subjects develop any clinical symptoms. This region of the thalamus has been shown to be predominantly connected to the frontal lobe, consistent with the pattern of cortical atrophy seen in the disease.

Contribution of FoxP3+ Tfr cells to overall human blood CXCR5+ T cells
The identification that T follicular helper (Tfh) cells is critical for the emergence of germinal centre responses prompted the study of CXCR5-expressing CD4+ T cell subsets in autoimmunity. However, circulating CXCR5-expressing T cells are heterogeneous by containing Forkhead box protein 3 (FoxP3)+ T follicular regulatory (Tfr) cells in addition to bona fide Tfh cells. Such heterogeneity may hamper the analysis of the contribution of specific follicular T cell subsets for autoimmune pathogenesis. Therefore, separate assessment of Tfh and Tfr populations offer greater opportunities for stratification of autoimmune patients, such as Sjögren's syndrome patients.

Gli Studi Iberici: passato, presente, futuro
This article intents to offer a panoramic view of the field of Iberian Studies, a fairly young academic field devoted to the study of Iberian literatures and cultures, which has gained some level of recognition and visibility in recent years. I will present its multiple genealogy, its different origins and theoretical foundations in diverse geographical and academic spaces; its current state, with a quantitative and qualitative analysis of its publications and of its level of institutionalization, and some proposals for its future development, based on the most recent debates and criticisms about this discipline. I will try to show that, without any intention of becoming homogenic or hegemonic, Iberian Studies have promoted new ways of studying Iberian cultures superseding linguistic, political or academic barriers.
