This is an open access article distributed under the terms of the Creative Commons Attribution License 4.0 (CC-BY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited., Background and objective: Mutations in the MAPT gene cause frontotemporal dementia (FTD). Most previous studies investigating the neuroanatomical signature of MAPT mutations have grouped all different mutations together and shown an association with focal atrophy of the temporal lobe. However, the variability in atrophy patterns between each particular MAPT mutation is less well characterised. We aimed to investigate whether there were distinct groups of MAPT mutation carriers based on their neuroanatomical signature. Methods: We applied Subtype and Stage Inference (SuStaIn), an unsupervised machine learning technique that identifies groups of individuals with distinct progression patterns, to characterise patterns of regional atrophy in MAPT-associated FTD within the Genetic FTD Initiative (GENFI) cohort study. Results: 82 MAPT mutation carriers were analysed, the majority of whom had P301L, IVS10+16 or R406W mutations, along with 48 healthy non-carriers. SuStaIn identified two groups of MAPT mutation carriers with distinct atrophy patterns: a 'temporal' subtype in which atrophy was most prominent in the hippocampus, amygdala, temporal cortex and insula, and a 'frontotemporal' subtype in which atrophy was more localised to the lateral temporal lobe and anterior insula, as well as the orbitofrontal and ventromedial prefrontal cortex and anterior cingulate. There was a one-to-one mapping between IVS10+16 and R406W mutations and the temporal subtype, and a near one-to-one mapping between P301L mutations and the frontotemporal subtype. There were differences in clinical symptoms and neuropsychological test scores between subtypes: the temporal subtype was associated with amnestic symptoms, whereas the frontotemporal subtype was associated with executive dysfunction. Discussion: Our results demonstrate that different MAPT mutations give rise to distinct atrophy patterns and clinical phenotype, providing insights into the underlying disease biology, and potential utility for patient stratification in therapeutic trials., The Dementia Research Centre is supported by Alzheimer's Research UK, Brain Research Trust, and The Wolfson Foundation. This work was supported by the NIHR Queen Square Dementia Biomedical Research Unit, the NIHR UCL/H Biomedical Research Centre and the Leonard Wolfson Experimental Neurology Centre (LWENC) Clinical Research Facility, NIHR Biomedical Research Centre at South London and Maudsley NHS Foundation Trust and Kings College London, as well as an Alzheimer's Society grant (AS-PG-16-007). This work was also supported by the MRC UK GENFI grant (MR/M023664/1), the Italian Ministry of Health (CoEN015 and Ricerca Corrente), and the Canadian Institutes of Health Research as part of a Centres of Excellence in Neurodegeneration grant, a Canadian Institutes of Health Research operating grant and The Bluefield Project, and the JPND GENFI-PROX grant (2019-02248). This work was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy within the framework of the Munich Cluster for Systems Neurology (EXC 2145 SyNergy ID 390857198). Nonfinancial support was also provided through the European Reference Network for Rare Neurologic Diseases (ERN-RND), 1 of 24 ERNs funded by the European Commission (ERNRND: 3HP 767231).

PURPOSE: To document and analyse the decision to withhold or withdraw life-sustaining treatment (LST) in a population of very old patients admitted to the ICU. METHODS: This prospective study included intensive care patients aged ≥ 80 years in 309 ICUs from 21 European countries with 30-day mortality follow-up. RESULTS: LST limitation was identified in 1356/5021 (27.2%) of patients: 15% had a withholding decision and 12.2% a withdrawal decision (including those with a previous withholding decision). Patients with LST limitation were older, more frail, more severely ill and less frequently electively admitted. Patients with withdrawal of LST were more frequently male and had a longer ICU length of stay. The ICU and 30-day mortality were, respectively, 29.1 and 53.1% in the withholding group and 82.2% and 93.1% in the withdrawal group. LST was less frequently limited in eastern and southern European countries than in northern Europe. The patient-independent factors associated with LST limitation were: acute ICU admission (OR 5.77, 95% CI 4.32-7.7), Clinical Frailty Scale (CFS) score (OR 2.08, 95% CI 1.78-2.42), increased age (each 5 years of increase in age had a OR of 1.22 (95% CI 1.12-1.34) and SOFA score [OR of 1.07 (95% CI 1.05-1.09 per point)]. The frequency of LST limitation was higher in countries with high GDP and was lower in religious countries. CONCLUSIONS: The most important patient variables associated with the instigation of LST limitation were acute admission, frailty, age, admission SOFA score and country.

Abstract

A inflamação, em geral, é uma resposta fisiológica do corpo para com diferentes tipos de lesão do tecido, provocando uma cascata coordenada de reacções celulares e bioquímicas. Distúrbios neurodegenerativos, inflamatórios e neoplásicos envolvem reacções neuroinflamatórias que isolam o tecido danificado e promovem respostas imunitárias. Da mesma forma, a neuroinflamação (NI) implica uma complexa e orquestrada resposta a vários estímulos no sistema nervoso central (SNC), com vista para a preservação do tecido e sua restauração. Reacções neuroinflamatórias envolvem uma resposta celular através da activação de células da linhagem do monócito, residentes ou circulantes. Microglia são as células residentes da linhagem dos monócitos no SNC e a sua activação, constitui uma característica principal da neuroinflamação. O processo envolve uma sobre expressão dos receptores da proteína translocadora de 18 kDa (TSPO) em células da linhagem dos monócitos/macrófagos e, no sistema nervoso central (SNC), pela activação da microglia. PK11195 é um ligando selectivo para o receptor da TSPO e, portanto, um identificador da microglia activada. O enantiómero (R) marcado radioactivamente com carbono-11, (R)-[N-metil-11 C]PK11195, é o radiotraçador mais utilizado para imagiologia in vivo da TSPO com PET. Neste trabalho, reportamos a optimização da síntese, purificação e reformulação de (R)-[N-metil-11 C] PK11195 pelo ‘captive solvente method’ com a finalidade de ser utilizado para imagem in vivo em estudos de PET. Carbono-11 é obtido sob a forma de [ 11 C]CO2 por irradiação de um alvo de gás (N2+O2 0,5%), utilizando a reacção nuclear 14 N(p,α) 11 C num ciclotrão. [ 11 C]CH3I é produzido por redução de [ 11 C]CO2 com LiAlH4/THF (0,1 M) via ‘fase liquida’ a [ 11 C]CH3OLi, e pela adição posterior de HI em um sistema de produção de iodeto de metilo, o [ 11 C]CH3I é destilado a 120ºC. Ao mesmo tempo, o [ 11 C]CH3I destilado é aprisionado num loop previamente carregado com uma solução da molécula precursora desmetilada (R)-[N-desmetil]PK11195 (dissolvida em 100μl de DMSO e saturada com 30mg de KOH), iniciando-se a reacção ao mesmo tempo que se aprisiona o [ 11 C]CH3I. Produtos da reacção ([11C]-X) passam por uma coluna HPLC semipreparativa de fase reversa (C18) para purificação. Finalmente, (R)-[N-metil-11 C]PK11195 foi formulado em 9ml de soro fisiológico (0,9%) e 1ml de EtOH e filtrado através de um filtro esterilizado de membrana de 0,22μm. O processo de síntese realiza-se em cerca de 35 minutos, e testes de controlo de qualidade foram realizados para garantir a boa qualidade do produto. 149,71±50,25mCi de vi (R)-[ 11 C]PK11195 foram obtidos no final da síntese com actividades específicas entre 15-25GBq/μmol num curto período de síntese. O ‘captive solvente loop’ proporciona uma maneira fácil e reprodutível para automatizar a produção de rotina de radiofármacos marcados com 11 C para uso humano. O método de produção é rápida, tendo em conta a curta meia-vida do carbono-11 (20,4 min), podendo-se produzir produtos finais com elevada pureza radioquímica e boa actividade específica.

Abstract

A doença de Alzheimer (DA) têm-se constituído, nos últimos anos, num sério problema de saúde pública nas sociedades ocidentais, um reflexo de uma população cada vez mais envelhecida fruto da melhoria geral da assistência médica e das mudanças demográficas daí decorrentes. Tratando-se uma doença neurodegenerativa a DA conduz à perda de diversas faculdades cognitivas e carateriza-se pela redução progressiva de tamanho e número das células cerebrais, a par da formação de emaranhados neurofibrilares (NFTs) no seu interior e placas de β-amilóide (Aβ) no espaço exterior. Na última década, o diagnóstico da DA ganhou um importante aliado com a possibilidade de realização de Tomografia por Emissão de Positrões (PET) com o radiofármaco [11C]PiB que apresenta afinidade pelas placas de Aβ. Recentemente, foi também possível aumentar a confiança deste diagnóstico complementando-o com a avaliação do metabolismo cerebral da glicose através da sua conjugação, no mesmo protocolo PET com a [18F]FDG. No que concerne à realidade portuguesa, o ICNAS, uma unidade orgânica de investigação da Universidade de Coimbra focada na Utilização Biomédica das Ciências Nucleares, que inclui na sua estrutura uma unidade de produção radiofarmacêutica com ciclotrão, é um local privilegiado para a realização de PET cerebral com [11C]PiB. Desde Abril de 2012 até Julho de 2014 foram já realizados 107 estudos com [11C]PiB, dos quais 37 fizeram parte de estudos sequenciais onde o mesmo doente realizou o estudo combinado com [11C]PiB e [18F]FDG.
