RESUMEN
Pulmonary rehabilitation (PR) is the bedrock of non-pharmacological treatment for people with COPD. Nonetheless, it is well described in the literature that unless the patient changes his behaviour, the benefits of PR programmes will decline in six to twelve months after finishing the programme. Therefore, maintenance programmes can address the problem of PR programmes' effect loss over time.Community care units can provide multidisciplinary care in the current Portuguese primary health care context. These units have an interdisciplinary team that aims to develop competencies in COPD patients to self-manage the disease.This study aims to test the effectiveness of a 12-month home-based PR programme (Rehab2Life) compared to usual care through a single-blind randomised controlled trial with two parallel groups. The Rehab2Life programme includes two distinct phases. The first is an 8-week PR programme delivered to both groups, and the second is a PR maintenance programme delivered to the intervention group after the initial eight weeks. The control group receive the usual care and regular appointments. The primary outcome is functional capacity, and secondary outcomes are dyspnea, Health-Related Quality of Life (HRQoL), number of exacerbations, symptoms burden, anxiety and depression symptoms, and physical activity.We expect to observe that the home-based PR programme brings clinically relevant benefits to the participants at the end of the first eight weeks and that, at 12 months after the maintenance phase of the programme, benefits are less dissipated than in the control group. We expect to identify the characteristics of the patients who benefit the most from home-based programmes.The trial was registered on 7 April 2022 at ClinicalTrials.gov (NCT05315505).
RESUMEN
OBJECTIVE: This systematic review aimed to evaluate if event-related potentials (ERPs) can be a relevant tool for cognitive dysfunction diagnosis in Multiple Sclerosis (MS). METHODS: Four databases were consulted (PubMed, Embase, Scielo, and Web of Science). The included studies should include adults with clear MS diagnoses, independently of having cognitive complaints, and all should have been submitted to ERPs (P300, N400 or mismatch negativity (MMN)). The main outcomes evaluated were ERPs' amplitude and/or latency. RESULTS: 425 studies were obtained initially from all databases, with 26 studies fulfilling the eligibility criteria. P300 was the most used ERP (25 studies), showing a reduced amplitude or an increased latency in 84% of those. N400 was evaluated in one study, showing also abnormal results. MMN was addressed in two studies with inconsistent findings. Some studies further suggest that ERPs may show earlier abnormal results compared with neuropsychological tests. CONCLUSIONS: Most MS patient groups revealed ERP abnormalities, suggesting that these neurophysiological tests may be a relevant and appropriate diagnostic aid method for cognitive impairment in MS. SIGNIFICANCE: The use of ERPs in MS patients seems able to demonstrate cognitive impairment and its use should be considered as part of the regular patient evaluation.

Chronic respiratory diseases are a dealing cause of death and disability worldwide. Their prevalence is steadily increasing and the exposure to environmental contaminants, including Flame Retardants (FRs), is being considered as a possible risk factor. Despite the widespread and continuous exposure to FRs, the role of these contaminants in chronic respiratory diseases is yet not clear. This study aims to systematically review the association between the exposure to FRs and chronic respiratory diseases. Searches were performed using the Cochrane Library, MEDLINE, EMBASE, PUBMED, SCOPUS, ISI Web of Science (Science and Social Science Index), WHO Global Health Library and CINAHL EBSCO. Among the initial 353 articles found, only 9 fulfilled the inclusion criteria and were included. No statistically significant increase in the risk for chronic respiratory diseases with exposure to FRs was found and therefore there is not enough evidence to support that FRs pose a significantly higher risk for the development or worsening of respiratory diseases. However, a non-significant trend for potential hazard was found for asthma and rhinitis/rhinoconjunctivitis, particularly considering urinary organophosphate esters (OPEs) including TNBP, TPHP, TCEP and TCIPP congeners/compounds. Most studies showed a predominance of moderate risk of bias, therefore the global strength of the evidence is low. The limitations of the studies here reviewed, and the potential hazardous effects herein identified highlights the need for good quality large-scale cohort studies in which biomarkers of exposure should be quantified in biological samples.

Background Pulmonary rehabilitation (PR) is formally indicated to all COPD patients in groups B and E. It positively impacts dyspnoea, health-related quality of life and exercise tolerance, reducing admissions among people with chronic obstructive pulmonary disease (COPD) who have had a recent exacerbation and symptoms of anxiety and depression. There is limited access to PR programmes in Portugal, partially due to insufficient resources or referrals. This study aims to characterise COPD patients and assess whether they have criteria for PR programmes. Data from this study may provide strategic information for healthcare organisations to differentiate and innovate their response to COPD patients. Methodology A cross-sectional study was conducted in an urban municipality in the northern region of Portugal. The sample was randomly extracted from the national primary electronic health records. The sample size (n = 339) was determined considering the population of COPD patients in this region (N = 2818), a 95% confidence level and a margin of error of 5%. Results In this population, the prevalence of COPD is 1.8%. Furthermore, in this sample, 40% (n = 136) of people diagnosed with COPD have a formal indication to participate in PR programmes, although only 14.2% (n = 48) of these patients had access to PR. Conclusion COPD is probably underdiagnosed in this Portuguese region. Most COPD patients have eligibility criteria to be offered PR programmes, although most of them do not benefit from this vital treatment. Investing in community and home-based programmes may increase PR access, reducing acute exacerbation of chronic obstructive pulmonary disease (AECOPD) admissions.
RESUMEN
Background: Asthma is one of the most common chronic respiratory diseases and one of the most frequent causes of hospital care. Objectives: To describe the clinical characteristics of asthma and factors associated with its control. Methods: A cross-sectional study was conducted at the Military Hospital in Luanda, from April 2018 to March 2019. Data collection was performed using questionnaires on asthma symptoms and treatment, socio-demographic and environmental questions, and a Global Initiative for Asthma (GINA) questionnaire to assess the level of asthma control. Ordinal logistic regression analyses were performed. We estimated odds ratios, for higher categories of asthma control. P<0.05 was considered significant. Results: The sample consisted of 305 asthmatics ≥18-years-old, 56% women, with a mean age of 41.3 years. About 28% of patients had controlled asthma, 36% partially controlled and 35% uncontrolled. Poor asthma control was associated with frequent use of short-acting beta-2 agonists [OR 5.70 (95%CI 2.37;13.7)], oral corticosteroids [OR 3.68 (95%CI 2.24;6.04)], and incorrect inhaler technique [OR 4.08 (95%CI 1.25;13.3)]. Conclusions: A significant number of adults living in Luanda have uncontrolled asthma due to the under-use of inhaled corticosteroid therapy. It is necessary to develop strategic management and prevention plans to improve Angolan asthmatics' medical care.

Abstract In Portugal, family doctors work with a well-defined list of patients to whom they provide healthcare throughout their lives. Several studies showed that larger list sizes are associa- ted with poorer health outcomes and compromise the quality of care. A significant increase in the average list size has been observed in recent years due to the Portuguese unfavorable socioeconomic context and the lack of family doctors. In 2017, the Portuguese Association of General and Fa- mily Medicine (APMGF) developed technical and scientific research that ultimately typified a set of different clinical practice contexts. It considers the geographic and socioeconomic characteristics and a set of population-based indicators, adjusting the list size according to the population's specific needs. Such adjustments ensure health care services with better quality, safety, efficacy, and personalized to their features. In this paper, a brief review is made on this topic, focusing on the work developed by APMGF and its main results.
Resumo Em Portugal, os médicos de família trabalham com uma lista bem definida de utentes, aos quais prestam cuidados de saúde ao longo da vida. Vários estudos mostraram que as dimensões maiores das listas estão associadas a piores resultados de saúde comprometedoras da qualidade do atendimento prestado. Devido ao contexto socioeconómico português desfavorável e à falta de médicos de família, tem-se verificado um aumento significativo da dimensão média das listas de utentes atribuídas aos médicos de família nos últimos anos. A Associação Portuguesa de Medicina Geral e Familiar (APMGF) desenvolveu, em 2017, uma investigação técnico-científica que acabou por tipificar diferentes contextos do exercício clínico. Este trabalho considerou as características geográficas e socioeconómicas, bem como um conjunto de indicadores demográficos, visando ajustar a dimensão das listas de acordo com as necessidades específicas da população. Com os ajustamentos propostos na gestão da dimensão das listas de utentes, será possível prestar serviços de saúde com mais qualidade, segurança, eficácia e obter ganhos decorrentes da maior personalização na prestação de cuidados. Neste artigo uma breve revisão é feita sobre este tópico, direcionando o enfoque para os resultados do trabalho desenvolvido pela APMGF.

ABSTRACT To assess the impact that educational interventions to improve inhaler techniques have on the clinical and functional control of asthma and COPD, we evaluated 44 participants before and after such an intervention. There was a significant decrease in the number of errors, and 20 patients (46%) significantly improved their technique regarding prior exhalation and breath hold. In the asthma group, there were significant improvements in the mean FEV1, FVC, and PEF (of 6.4%, 8.6%, and 8.3% respectively). Those improvements were accompanied by improvements in Control of Allergic Rhinitis and Asthma Test scores but not in Asthma Control Test scores. In the COPD group, there were no significant variations. In asthma patients, educational interventions appear to improve inhaler technique, clinical control, and functional control.
RESUMO Para avaliar o impacto do ensino da técnica inalatória no controle clínico e funcional de pacientes com asma ou DPOC, incluíram-se 44 participantes antes e após essa intervenção. Houve uma diminuição significativa no número de erros cometidos, sendo que 20 pacientes (46%) melhoraram significativamente sua técnica na expiração prévia e apneia final. No grupo asma, houve significativa melhora nas médias de FEV1 (6,4%), CVF (8,6%) e PFE (8,3%), e essa melhora correlacionou-se com os resultados no Control of Allergic Rhinitis and Asthma Test, mas não com os do Asthma Control Test. No grupo DPOC, não houve variações significativas. O ensino da técnica inalatória parece melhorar seu desempenho e os controles clínico e funcional em pacientes com asma.
