- Associação entre Infeção por SARS-CoV-2 e Saúde Mental aos 12 Meses: Um Estudo na Região de Lisboa e Vale do Tejo (LVT)Publication . Cristóvão, Filipa; Moniz, Marta; Goes, Ana Rita; Soares, Patrícia; Leite, AndreiaIntrodução: A condição pós-COVID-19 afeta indivíduos com história de infeção por síndrome respiratória aguda grave devido a coronavírus 2 (SARS-CoV-2) e pode incluir sintomas persistentes como fadiga, alterações cognitivas e perturbações psicológicas (e.g., ansiedade, depressão, perturbação de stress pós-traumático (PTSD)), mesmo após 12 meses. Apesar de existirem dados sobre sintomas psicológicos nas fases iniciais da infeção, a sua persistência a longo prazo continua pouco explorada, particularmente em Portugal. Este estudo teve como objetivo investigar a associação entre infeção por SARS-CoV-2 e sintomas psicológicos aos 12 meses, em residentes da região de LVT. Métodos: Estudo observacional transversal analítico, incluindo indivíduos residentes em LVT que realizaram teste de reação em cadeia de polimerase (PCR) ou teste rápido de antigénio (TRAg) em agosto de 2022 com base na informação registada no Sistema Nacional de Vigilância Epidemiológica. A exposição foi o resultado do teste SARS-CoV-2 (positivo ou negativo); os outcomes foram sintomas de ansiedade, depressão e PTSD. Os dados foram recolhidos por entrevista telefónica (outubro-novembro de 2023), utilizando o Patient Health Questionnaire de 2 itens (PHQ-2), Patient Health Questionnaire de 9 itens (PHQ-9), General Anxiety Disorder Questionnaire de 2 itens (GAD-2), General Anxiety Disorder Questionnaire de 7 itens (GAD-7) e Primary Care PTSD Screen for DSM-5 (PC-PTSD-5). Para estimar a associação através de razões de prevalência ajustadas (RPa) foram usadas regressões de Poisson com variância robusta, ajustando para confundimento (idade, sexo, situação profissional, nível de escolaridade, comorbilidades, consumo de tabaco, consumo de álcool). Resultados: Foram incluídos 767 participantes (528 positivos, 239 negativos). A prevalência de sintomas depressivos foi de 6,0%, mais elevada nos positivos (7,0% vs. 3,8%). Após ajustamento, observou-se uma associação significativa (razão de prevalência ajustada (RPa )= 2,07; IC95%: 1,01–4,26). A prevalência de ansiedade foi também superior nos positivos (7,2% vs. 3,8%), sem significância estatística (RPa = 1,84; IC95%: 0,91–3,80). A prevalência de PTSD foi baixa (0,8%), pelo que não foram estimadas medidas de associação. Discussão e Conclusão: Os resultados mostraram maior prevalência de sintomas depressivos entre indivíduos previamente infetados por SARS-CoV-2, associação que se manteve após ajustamento e em consonância com estudos internacionais. Observou-se tendência não significativa para ansiedade e ausência de diferenças em PTSD, possivelmente relacionadas com o reduzido número de casos e a predomínio de infeções ligeiras. O contexto epidemiológico poderá ter atenuado as associações. Entre as limitações destacam-se o desenho transversal, autorreporte, confundimento residual e restrição geográfica e temporal da amostra. Em conclusão, os dados sugerem associação entre infeção e sintomas depressivos a longo prazo, sublinhando a importância da vigilância em saúde mental no período pós infecção.
- Direct costs with dementia hospitalization and its determinants in Portugal in 2018Publication . Madeira, Francisco; Moniz, Marta; Leite, Andreia; Alves, JoanaBackground/Objectives: Major neurocognitive disorders, as is the case of dementia, are characterised by a decline in cognitive abilities, leading to adverse health outcomes and deterioration in quality of life. The projected rise in diagnoses for the coming decades represent a public health concern, impacting patients and society, and placing a considerable financial burden on healthcare systems. This study aims to estimate hospitalisation costs with dementia in Portugal in 2018, and its determinants. Methods: We used inpatient data from the Portuguese publicly financed hospitals database (Base de Dados de Morbilidade Hospitalar, ACSS) for 2018. We selected hospitalization records (n = 25,830) with dementia-related diagnosis, either primary or non-primary, based on ICD-10. We computed average costs for inpatient cases, using tariffs from national legislation, stratifying by dementia type. We performed a multivariate regression analysis (gamma, log link) for assessing costs’ determinants (sex, age, region, number of comorbidities, type of dementia, medical or surgical inpatient, and destination after discharge). Results: The average cost per hospitalisation was 3,084 €. Stratifying by type of dementia, Alzheimer's patients accounted for 2,441 €, vascular dementia for 4,079 €, and other degenerative diseases (including Lewy body and frontotemporal dementia) for 2,515 €. This represented a national economic burden of 79.7 million €. Younger individuals (55-64, 65-74, and 75-84) incurred significantly higher inpatient costs of 1,042 €, 676 €, and 216 €, respectively, compared to 85+. Compared to unspecified dementia, Alzheimer's was associated with higher costs, while patients with other dementia showed no significant cost differences. The costs were higher (p < 0.001) with each additional comorbidity (+23 €) and severity level (+1,439 €). Compared to deceased (p < 0.001), patients discharged home had lower costs (-328 €), while those discharged to other settings incurred higher costs (+471 €). Non-surgical cases were 3,961€ less costly than surgical ones (p < 0.001). Conclusions/Recommendations: Dementia-related hospitalisations imposed a substantial financial burden on the Portuguese public healthcare system in 2018 and are expected to rise in the future. Costs were driven by key factors such as age, number of comorbidities, severity, destination of discharge, and hospitalisation type.
- Individual risk factors associated with SARS-CoV-2 infection during Alpha variant in high-income countries: a systematic review and meta-analysisPublication . Moniz, Marta; Pereira, Sofia; Soares, Patricia; Aguiar, Pedro; Donato, Helena; Leite, AndreiaObjectives: This study aimed to systematically appraise risk factors associated with SARS-CoV-2 infection in high-income countries during the period of predominance of the Alpha variant (January 2020 to April 2021). Methods: Four electronic databases were used to search observational studies. Literature search, study screening, data extraction and quality assessment were conducted by two authors independently. Meta-analyses were conducted for each risk factor, when appropriate. Results: From 12,094 studies, 27 were included. The larger sample size was 17,288,532 participants, more women were included, and the age range was 18-117 years old. Meta-analyses identified men [Odds Ratio (OR): 1.23, 95% Confidence Interval (CI): 1.97-1.42], non-white ethnicity (OR: 1.63, 95% CI: 1.39-1.91), household number (OR: 1.08, 95% CI: 1.06-1.10), diabetes (OR: 1.22, 95% CI: 1.08-1.37), cancer (OR: 0.82, 95% CI: 0.68-0.98), cardiovascular diseases (OR: 0.92, 95% CI: 0.84-1.00), asthma (OR: 0.83, 95% CI: 0.75-0.92) and ischemic heart disease (OR: 0.82, 95% CI: 0.74-0.91) as associated with SARS-CoV-2 infection. Conclusion: This study indicated several risk factors for SARS-CoV-2 infection. Due to the heterogeneity of the studies included, more studies are needed to understand the factors that increase the risk for SARS-CoV-2 infection.
- Investigating the role of symptom valorisation in tuberculosis patient delay in urban areas in PortugalPublication . de Morais, Margarida; Sousa, Sofia; Marques, Jéssica; Moniz, Marta; Duarte, Raquel; Leite, Andreia; Soares, Patricia; Carreira, Mário; Pereira, Sofia; Alves, Catarina; Alves, Filipe; Rodrigues, Ana; Moreira, Ana; Cardoso, Márcia; Mota, Sandra; Gomes, Ana; Ferreira, Liliana; Lopes, Marta; Correia, Isabel; Rachadell, Juan; Gameiro, Maria; Dias, Ângela; Pereira, Manuel; Gonçalves, Jorge; Gonçalves, Maria; Taveira, Adriana; Neves, Celene; Silva, Lucinda; Mendes, Maria; Teixeira, Maria; Pereira, Maria; Piedade, Milena; Teixeira, Antónia; Carvalho, CarlosBackground: Diagnosis delay contributes to increased tuberculosis (TB) transmission and morbimortality. TB incidence has been decreasing in Portugal, but median patient delay (PD) has risen. Symptom valorisation may determine PD by influencing help-seeking behaviour. We aimed to analyse the association between symptom valorisation and PD, while characterising individuals who disregarded their symptoms. Methods: A cross-sectional study was conducted among TB patients in Lisbon and Oporto in 2019 - 2021. Subjects who delayed seeking care because they did not value their symptoms or thought these would go away on their own were considered to have disregarded their symptoms. PD was categorised using a 21-day cut-off, and a 30-day cut-off for sensitivity analysis. We estimated the effect of symptom valorisation on PD through a directed acyclic graph. Then, a multivariable regression analysis characterised patients that disregarded their symptoms, adjusting for relevant variables. We fitted Poisson regression models to estimate crude and adjusted prevalence ratios (PR). Results: The study included 75 patients. Median PD was 25 days (IQR 11.5-63.5), and 56.0% of participants had PD exceeding 21 days. Symptom disregard was reported by 38.7% of patients. Patients who did not value their symptoms had higher prevalence of PD exceeding 21 days compared to those who valued their symptoms [PR 1.59 (95% CI 1.05-2.42)]. The sensitivity analysis showed consistent point estimates but wider confidence intervals [PR 1.39 (95% CI 0.77-2.55)]. Being a smoker was a risk factor for symptom disregard [PR 2.35 (95% CI 1.14-4.82)], while living in Oporto [PR 0.35 (95% CI 0.16-0.75)] and having higher household incomes [PR 0.39 (95% CI 0.17-0.94)] were protective factors. Conclusions: These findings emphasise the importance of symptom valorisation in timely TB diagnosis. Patients who did not value their symptoms had longer PD, indicating a need for interventions to improve symptom recognition. Our findings also corroborate the importance of the socioeconomic determinants of health, highlighting tobacco as a risk factor both for TB and for PD.
- Is a tiered restrictions system an effective intervention for COVID-19 control? Results from Portugal, November-December 2020Publication . Moniz, Marta; Soares, Patricia; Nunes, Baltazar; Leite, AndreiaBackground: In November 2020, similar to other European countries, Portugal implemented a tiered restrictions system to control the COVID-19 pandemic. We aimed to compare the COVID-19 growth rate across tiers to assess the effect of a tiered restrictions system in Portugal, using models with different times between tiers assessment. Our hypothesis was that being in a higher tier brings a faster deceleration in the growth rate than being in a lower tier. Methods: The national database of notified COVID-19 cases and publicly available data were used to analyse the effect of the tiered restrictions system on the COVID-19 incidence growth rate. The tiers were based on the European Centre for Disease Control risk classification: moderate, high, very and extremely high. We used a generalised mixed effects regression model to estimate the growth rate ratio (GRR) for each tier, comparing the growth rates of higher tiers using moderate tier as reference. Three models were fitted using different times between tiers assessment, separated by 14 days. Results: We included 156 034 cases. Very high tier was the most frequent combination in all the three moments assessed (21.2%), and almost 50% of the municipalities never changed tier during the study period. Immediately after the tiers implementation, a reduction was identified in the municipalities in high tier (GRR high tier: 0.90 [95%CI: 0.79; 1.02]) and very high tier (GRR very high tier: 0.68 [95%CI: 0.61; 0.77]), however with some imprecision in the 95% confidence interval for the high tier. A reduction in very high tier growth rate was identified two weeks (GRR: 0.79 [95%CI: 0.71; 0.88]) and four weeks (GRR: 0.77 [95%CI: 0.74; 0.82]) after the implementation, compared to moderate tier. In high tier, a reduction was also identified in both times, although smaller. Conclusions: We observed a reduction in the growth rate in very high tier after the tiered restriction system was implemented, but we also observed a lag between tiered restriction system implementation and the onset of consequent effects. This could suggest the importance of early implementation of stricter measures for pandemic control. Thus, studies analysing a broader period of time are needed.
- LOCUS (LOng Covid-Understanding Symptoms, events and use of services in Portugal): A three-component study protocolPublication . Dinis Teixeira, J.P.; Santos, Mário J.D.S.; Soares, Patricia; Azevedo, Luísa de; Barbosa, Patrícia; Boas, Andreia Vilas; Cordeiro, João V.; Dias, Sónia; Fonseca, Marta; Goes, Ana Rita; Lobão, Maria João; Moniz, Marta; Nóbrega, Sofia; Peralta-Santos, André; Ramos, Víctor; Rocha, João Victor; da Silva, António Carlos; Brazão, Maria da Luz; Leite, Andreia; Nunes, CarlaApproximately 10% of patients experience symptoms of Post COVID-19 Condition (PCC) after a SARS-CoV-2 infection. Akin acute COVID-19, PCC may impact a multitude of organs and systems, such as the cardiovascular, respiratory, musculoskeletal, and neurological systems. The frequency and associated risk factors of PCC are still unclear among both community and hospital settings in individuals with a history of COVID-19. The LOCUS study was designed to clarify the PCC’s burden and associated risk factors. LOCUS is a multi-component study that encompasses three complementary building blocks. The “Cardiovascular and respiratory events following COVID-19” component is set to estimate the incidence of cardiovascular and respiratory events after COVID-19 in eight Portuguese hospitals via electronic health records consultation. The “Physical and mental symptoms following COVID-19” component aims to address the community prevalence of self-reported PCC symptoms through a questionnaire-based approach. Finally, the "Treating and living with Post COVID-19 Condition" component will employ semi-structured interviews and focus groups to characterise reported experiences of using or working in healthcare and community services for the treatment of PCC symptoms. This multi-component study represents an innovative approach to exploring the health consequences of PCC. Its results are expected to provide a key contribution to the optimisation of healthcare services design.
- Long COVID is not the same for everyone: a hierarchical cluster analysis of Long COVID symptoms 9 and 12 months after SARS-CoV-2 testPublication . Moniz, Marta; Ruivinho, Carolina; Goes, Ana Rita; Soares, Patricia; Leite, AndreiaBackground: Identifying symptom clusters in Long COVID is necessary for developing effective therapies for this diverse condition and improving the quality of life of those affected by this heterogeneous condition. In this study, we aimed to identify and compare symptom clusters at 9 and 12 months after a SARS-CoV-2 positive test and describe each cluster regarding factors at infection. Methods: This is a cross-sectional study with individuals randomly selected from the Portuguese National System of Epidemiological Surveillance (SINAVE) database. Individuals who had a positive RT-PCR SARS-CoV-2 test in August 2022 were contacted to participate in a telephonic interview approximately 9 and 12 months after the test. A hierarchical clustering analysis was performed, using Euclidean distance and Ward's linkage. Clustering was performed in the 35 symptoms reported 9 and 12 months after the SARS-CoV-2 positive test and characterised considering age, sex, pre-existing health conditions and symptoms at time of SARS-CoV-2 infection. Results: 552 individuals were included at 9 months and 458 at 12 months. The median age was 52 years (IQR: 40-64 years) and 59% were female. Hypertension and high cholesterol were the most frequently reported pre-existing health conditions. Memory loss, fatigue or weakness and joint pain were the most frequent symptoms reported 9 and 12 months after the positive test. Four clusters were identified at both times: no or minor symptoms; multi-symptoms; joint pain; and neurocognitive-related symptoms. Clusters remained similar in both times, but, within the neurocognitive cluster, memory loss and concentration issues increased in frequency at 12 months. Multi-symptoms cluster had older people, more females and more pre-existing health conditions at 9 months. However, at 12 months, older people and those with more pre-existing health conditions were in joint pain cluster. Conclusions: Our results suggest that Long COVID is not the same for everyone. In our study, clusters remained similar at 9 and 12 months, except for a slight variation in the frequency of symptoms that composed each cluster. Understanding Long COVID clusters might help identify treatments for this condition. However, further validation of the observed clusters and analysis of its risk factors is needed.
