Late Onset Neuromyelitis Optica Spectrum Disorders (LONMOSD) from a Nationwide Portuguese Study: Anti-AQP4 Positive, Anti-MOG Positive and Seronegative Subgroups
No full textIntroduction: Several neuroimmunological disorders have distinct phenotypes according to the age of onset, as in multiple sclerosis or myasthenia gravis. It is also described that late onset NMOSD (LONMOSD) has a different phenotype.
Objective: To describe the clinical/demographic characteristics of the LONMOSD and distinguish them from those with early onset (EONMOSD).
Methods: From a nationwide Portuguese NMOSD study we analyzed the clinical/demographic characteristics of the LONMOSD.
Results: From the 180 Portuguese patients 45 had disease onset after 50 years old, 80% were female. 23 had anti-AQP4 antibodies (51.1%), 13 anti-MOG antibodies (28.9%) and 9 were double seronegative (20.0%). The most common presenting phenotypes in LONMOSD were transverse myelitis (53.3%) and optic neuritis (26.7%), without difference from EONMOSD (p = 0.074). The mean EDSS for LONMOSD was 6.0 (SD=2.8), after a mean follow-up time of 4.58 (SD=4.47) years, which was significantly greater than the mean EDSS of EONMOSD (3.25, SD=1.80)(p = 0.022). Anti-AQP4 antibodies positive LONMOSD patients had increased disability compared to anti-MOG antibodies positive LONMOSD (p = 0.022). The survival analysis showed a reduced time to use a cane for LONMOSD, irrespective of serostatus (p<0.001).
Conclusions: LONMOSD has increased disability and faster progression, despite no differences in the presenting clinical phenotype were seen in our cohort.info:eu-repo/semantics/publishedVersio
Teledermatologia e a Pandemia Covid-19: Experiência de um Centro Português
No full textIntroduction: In order to maintain assistential activity while ensuring social distancing and mobility restrictions imposed during the COVID-19 pandemic, the Dermatovenereology Department of Hospital de Santo António dos Capuchos implemented an asynchronous teledermatology platform based on e-mail and smartphones. This study aims to evaluate its application to urgent outpatient and inpatient consultations while considering its benefits and limitations. Methods: All written communications received via e-mail or smartphone between April 1, 2020 and April 31, 2021 were reviewed. Data was evaluated and statistical analysis was made using SPSS Statistics 25® software. Results: We reviewed 471 referrals (329 for outpatient and 142 for inpatient urgent consultations). E-mail was the most used platform (68.8%) and most referrals were composed of clinical information and clinical images (70.3%). Only 29% of these contained adequate clinical information and clinical images simultaneously. The majority of referrals received a response by a dermatologist in less than 24 hours (89%) and conversion to in-person evaluation was made in 58% of cases. The average time for in-person evaluation after triage was 0.25 days for inpatients and 4 days for outpatients. Conclusion: The COVID-19 pandemic hastened teledermatology implementation in order to maintain good healthcare. This study demonstrates that these platforms where wildly accepted by healthcare professionals and patients and remote consultations were possible in a significant percentage of cases. Teledermatology struggles with its own limitations and can never fully replace in-person evaluation, but can present itself as a useful tool in daily practice.Introdução: Com o objectivo de manter a actividade assistencial numa altura em que o distanciamento social e as restrições de mobilidade entre hospitais consequentes à pandemia COVID-19 se apresentavam como fundamentais, o departamento de Dermatovenereologia do Hospital de Santo António dos Capuchos implementou uma plataforma assíncrona de teledermatologia baseada em e-mail e smartphones. Este estudo pretende avaliar a sua aplicação a consultas de urgência de ambulatório e internamento, dando destaque aos seus benefícios e limitações. Métodos: Todas as comunicações escritas recebidas por e-mail ou smartphone entre 1 de Abril de 2020 e 31 de Abril de 2021 foram analisadas. Os dados foram avaliados e foi realizada análise estatística com recurso ao software SPSS Statistics 25®. Resultados: Foram analisadas 471 referenciações (329 consultas urgentes de ambulatório e 142 consultas urgentes em internamento). O e-mail foi a plataforma mais usada (68.8%) e a maioria das referenciações eram compostas por informação clínica escrita e imagens clínicas (70.3%). Apenas 29% destas continham, em simultâneo, informação clínica e imagens clínicas adequadas. A maior parte dos pedidos recebeu uma resposta por um dermatologista em menos de 24 horas (89%) e, em 58% dos casos, foi efectuada uma conversão a consulta presencial. O tempo médio para uma consulta presencial após triagem foi de 0.25 dias para consultas em internamento e 4 dias para consultas de ambulatório. Conclusão: A pandemia COVID-19 acelerou a implementação da teledermatologia de modo a assegurar a manutenção de bons cuidados de saúde. Este estudo demonstrou que estas plataformas foram amplamente adoptadas por profissionais de saúde e doentes e a realização de consultas remotas foi possível numa percentagem significativa de casos. A teledermatologia apresenta várias limitações e nunca poderá substituir integralmente uma avaliação presencial, podendo ser, no entanto, uma ferramenta útil no dia-a-dia.info:eu-repo/semantics/publishedVersio
Behavioural Patterns in Allergic Rhinitis Medication in Europe: A Study Using MASK‐Air ® Real‐World Data
No full textBackground: Co-medication is common among patients with allergic rhinitis (AR), but its dimension and patterns are unknown. This is particularly relevant since AR is understood differently across European countries, as reflected by rhinitis-related search patterns in Google Trends. This study aims to assess AR co-medication and its regional patterns in Europe, using real-world data.
Methods: We analysed 2015-2020 MASK-air® European data. We compared days under no medication, monotherapy and co-medication using the visual analogue scale (VAS) levels for overall allergic symptoms ('VAS Global Symptoms') and impact of AR on work. We assessed the monthly use of different medication schemes, performing separate analyses by region (defined geographically or by Google Trends patterns). We estimated the average number of different drugs reported per patient within 1 year.
Results: We analysed 222,024 days (13,122 users), including 63,887 days (28.8%) under monotherapy and 38,315 (17.3%) under co-medication. The median 'VAS Global Symptoms' was 7 for no medication days, 14 for monotherapy and 21 for co-medication (p < .001). Medication use peaked during the spring, with similar patterns across different European regions (defined geographically or by Google Trends). Oral H1 -antihistamines were the most common medication in single and co-medication. Each patient reported using an annual average of 2.7 drugs, with 80% reporting two or more.
Conclusions: Allergic rhinitis medication patterns are similar across European regions. One third of treatment days involved co-medication. These findings suggest that patients treat themselves according to their symptoms (irrespective of how they understand AR) and that co-medication use is driven by symptom severity.info:eu-repo/semantics/publishedVersio
Acute Haematogenous Osteomyelitis in Lisbon: An Unexpectedly High Association with Myositis and Arthritis
No full textIntroduction: Despite the current trend towards less aggressive therapeutic approaches, acute haematogenous osteomyelitis (AHO) continues to be a challenge and is associated with significant morbidity worldwide. Our aim was to determine if 80% compliance with current protocol was achieved, identify complications and associated risk factors and analyse trends in aetiology and management of AHO in children.
Methods: We conducted a longitudinal, observational, single-centre study in patients with AHO aged less than 18 years admitted to a paediatric hospital, between 2008 and 2018, divided into 2 cohorts (before and after 2014). Demographic, clinical data and disease progression were analysed.
Results: The study included 71 children with AHO, 56% male, with a median age of 3 years (interquartile range, 1-11). We found a 1.8-fold increase of cases in the last 5 years. The causative agent was identified in 37% of cases: MSSA (54%), MRSA (4%), Streptococcus pyogenes (19%), Kingella kingae (12%), Streptococcus pneumoniae (8%), and Neisseria meningitidis (4%). Complications were identified in 45% of patients and sequelae in 3.6%. In recent years, there was an increase in myositis (30% vs. 7%; p=0.02), septic arthritis (68% vs. 37.2%; p=0.012) and in the proportion of patients treated for less than 4 weeks (37% vs. 3.5%; p=0.012), with a similar sequelae rates. The risk factors for complications were age 3 or more years, CRP levels of 20mg/l or higher, time elapsed between onset and admission of 5 or more days and positive culture, although on multivariate analysis only positive culture was significant. The presence of complications was a risk factor for sequelae at 6 months.
Conclusions: Our study confirms that AHO can be aggressive. The identification of risk factors for complications may be fundamental for management.info:eu-repo/semantics/publishedVersio
Invasive and Subcutaneous Infections Caused by Filamentous Fungi: Report from a Portuguese Multicentric Surveillance Program
No full textInvasive fungal infections (IFI) have significantly increased over the past years due to advances in medical care for the at-risk immunocompromised population. IFI are often difficult to diagnose and manage, and can be associated with substantial morbidity and mortality. This study aims to contribute to understanding the etiology of invasive and subcutaneous fungal infections, their associated risk factors, and to perceive the outcome of patients who developed invasive disease, raising awareness of these infections at a local level but also in a global context. A laboratory surveillance approach was conducted over a seven-year period and included: (i) cases of invasive and subcutaneous fungal infections caused by filamentous/dimorphic fungi, confirmed by either microscopy or positive culture from sterile samples, (ii) cases diagnosed as probable IFI according to the criteria established by EORTC/MSG when duly substantiated. Fourteen Portuguese laboratories were enrolled. Cases included in this study were classified according to the new consensus definitions of invasive fungal diseases (IFD) published in 2020 as follows: proven IFI (N = 31), subcutaneous fungal infection (N = 23). Those proven deep fungal infections (N = 54) totalized 71.1% of the total cases, whereas 28.9% were classified as probable IFI (N = 22). It was possible to identify the etiological fungal agent in 73 cases (96%). Aspergillus was the most frequent genera detected, but endemic dimorphic fungi represented 14.47% (N = 11) of the total cases. Despite the small number of cases, a high diversity of species were involved in deep fungal infections. This fact has implications for clinical and laboratory diagnosis, and on the therapeutic management of these infections, since different species, even within the same genus, can present diverse patterns of susceptibility to antifungals.info:eu-repo/semantics/publishedVersio
Monitoração Remota Invasiva das Pressões na Artéria Pulmonar em Doentes com Insuficiência Cardíaca: Experiência Inicial em Portugal no Contexto da Pandemia Covid-19
No full textBackground: Decompensated heart failure (HF) is associated with poor short- and long-term prognosis. Remote invasive monitoring of pulmonary artery pressures (PAP) enables early detection of HF decompensation before symptoms occur and may improve clinical outcomes. We aimed to describe our initial experience with the use of the CardioMEMS™ remote monitoring system in patients with HF, including its safety and effectiveness.
Methods and results: Five patients with HF in New York Heart Association class III and at least one hospitalization due to decompensated HF in last 12 months, who underwent invasive remote monitoring of PAP, were included in this prospective registry. The median age was 66.0 years (interquartile range [IQR] 50.5-77.5 years), 80.0% were men and all had HF with reduced ejection fraction. The pulmonary artery (PA) sensor was placed in a left PA branch in all patients and no major procedural complications occurred. In median follow-up of 40 days (IQR 40-61 days), a total of 271 pressure readings were transmitted, patient compliance was 100% and freedom from sensor failure 98.1%. In three patients, PAP remained within the goal during follow-up. Two patients presented an increase in PAP to values above the targets, despite the absence of symptom worsening. These required dietary and diuretic dose adjustment, without the need for outpatient clinic visits, which reduced PAP. No hospitalizations for HF or deaths occurred during follow-up.
Conclusion: Hemodynamic-guided HF monitoring was safe and effective and may be a useful adjunctive tool to the standard-of-care management in selected HF patients, particularly in the context of the COVID-19 pandemic, where a reduction in the number of health care visits may be desirable.Introdução: A insuficiência cardíaca (IC) descompensada está associada a mau prognóstico em
curto e longo prazo. A monitoração remota invasiva da pressão na artéria pulmonar (PAP) possibilita a deteção precoce da descompensação da IC, previamente ao início dos sintomas, pode
melhorar os resultados clínicos. Descrevemos a experiência inicial com o uso do sistema de
monitoração remota CardioMEMSTM em doentes com IC, inclusive a sua segurança e eficácia.
Métodos e resultados: Foram incluídos prospetivamente cinco doentes com IC em classe III da
New York Heart Association, com pelo menos uma hospitalização por IC descompensada nos últimos 12 meses, submetidos a implantação de sistema de monitoração remota invasiva da PAP. A
mediana de idade foi de 66 anos (intervalo interquartil [IIQ] 50,5-77,5 anos), 80% eram do sexo
masculino e todos apresentavam IC com fração de ejeção reduzida. O sensor de PAP foi colocado num ramo da artéria pulmonar esquerda em todos os doentes, não ocorreram complicações
major. Durante o follow-up mediano de 40 dias (IIQ 40-61 dias), foram transmitidas 271 leituras,
verificou-se uma adesão dos doentes de 100% e taxa de transmissão bem-sucedida de 98,1%.
A PAP manteve-se dentro do objetivo em três doentes durante o follow-up. Apesar de continuarem assintomáticos, dois doentes apresentaram valores das PAP acima do alvo. Foi feito ajuste
dietético e da dose de diurético, sem necessidade de visitas clínicas presenciais, objetivou-se
uma redução efetiva das PAP. Durante o seguimento, não se registaram hospitalizações por IC
ou óbitos.
Conclusão: A monitoração da IC guiada pela hemodinâmica demonstrou ser segura e eficaz,
pode assumir-se como uma ferramenta útil no manejo de doentes com IC, particularmente
no contexto da pandemia Covid-19, quando é desejável uma redução do número de consultas

Early Anticoagulation in Patients with Acute Ischemic Stroke Due to Atrial Fibrillation: A Systematic Review and Meta-Analysis
No full textIntroduction: There is uncertainty regarding the optimal timing for initiation of oral anticoagulation in patients with acute ischemic stroke (AIS) due to atrial fibrillation (AF). Methods: We performed a systematic review and meta-analysis of randomized-controlled clinical trials (RCTs) and prospective observational studies to assess the efficacy and safety of early anticoagulation in AF-related AIS (within 1 week versus 2 weeks). A second comparison was performed assessing the efficacy and safety of direct oral anticoagulants (DOACs) versus vitamin-K antagonists (VKAs) in the two early time windows. The outcomes of interest were IS recurrence, all-cause mortality, symptomatic intracerebral haemorrhage (sICH) and any ICH. Results: Eight eligible studies (6 observational, 2 RCTs) were identified, including 5616 patients with AF-related AIS who received early anticoagulation. Patients that received anticoagulants within the first week after index stroke had similar rate of recurrent IS, sICH and all-cause mortality compared to patients that received anticoagulation within two weeks (test for subgroup differences p = 0.1677; p = 0.8941; and p = 0.7786, respectively). When DOACs were compared to VKAs, there was a significant decline of IS recurrence in DOAC-treated patients compared to VKAs (RR: 0.65; 95%CI: 0.52-0.82), which was evident in both time windows of treatment initiation. DOACs were also associated with lower likelihood of sICH and all-cause mortality. Conclusions: Early initiation of anticoagulation within the first week may have a similar efficacy and safety profile compared to later anticoagulation (within two weeks), while DOACs seem more effective in terms of IS recurrence and survival compared to VKAs.info:eu-repo/semantics/publishedVersio
Anatomical Basis, Histological Findings and Hemodinamics in the Modern Perfusion Model for Human Corpses
No full textsSeveral modern human cadaveric fixation methods are subject to permanent evaluation. Formaldehyde is the
oldest and still the most widely used method of embalming. However, the International Agency for Research on Cancer has proven its high carcinogenic potential and its use was banned, with the recommendation of research for better alternatives in the conservation of corpses. The embalming method of excellence, which preserves all features, while keeping the disinfectant properties against cadaveric decomposition was proposed by João Goyri O’Neill. Their method was considered “the most modern and efficient technique in cadaveric preservation”. The aim of this present study was to analyze the quality of this original perfusion technique, at the organic level, based on central and peripheral hemodynamics. The cadaveric material was embalmed through a pulsed arterial perfusion system, connected to an automatic intermittent pump, that permits stability
of the microvascular network, as well as the computerized measurement of the main perfusion parameters, such as flow and pressure. This procedure ensures good preservation of color, elasticity, texture, flexibility and fresh appearance, for several years. The morphological characteristics of the organs exhibited astonishing similarity to the living organic tissues, even several years after embalming and high freezing. Microscopic analysis demonstrated preservation of the structure of vessels, such as the aorta. Further studies on the integrity of the endocardial layer of the heart will enable to adapt the intermittent perfusion pump system to best simulate cardiac rhythm and arterial pulse, during cadaveric surgical training.info:eu-repo/semantics/publishedVersio
