It is critical to develop tailored strategies increase acceptability of the COVID-19 vaccine and decrease hesitancy. Hence, this study aims assess identify factors associated with hesitancy in Portugal. We used data from a community-based survey, “COVID-19 Barometer: Social Opinion”, which includes regarding intention take vaccines, health status, risk perception Portugal September 2020 January 2021. multinomial regression delay or refuse vaccines. was high: 56% would wait 9% refuse. Several...
Background: Knowledge on the settings and activities associated with a higher risk of SARS-CoV-2 transmission is essential to inform decision-making. We thus designed case-control study identify relevant for community severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Portugal. Methods: evaluated 1,088 cases, identified through national surveillance system, 787 controls, recruited using random digit dialing. Sociodemographic characteristics, individual protective measures, or...
The COVID-19 pandemic has resulted in changes healthcare use. This study aimed to identify factors associated with a patient's decision avoid and/or delay during the pandemic. We used data from community-based survey Portugal July 2020 August 2021, "COVID-19 Barometer: Social Opinion", which included regarding health services use, risk perception and confidence services. framed our analysis under Andersen's Behavioural Model of Health Services Use utilised Poisson regression avoidance...
Abstract Background Early diagnosis and treatment of pulmonary tuberculosis (PTB) is essential for an effective control the (TB) epidemic. Delayed TB increases chance complications mortality patients, enhances transmission in population. Therefore, aim this study was to characterize patient, healthcare total delay diagnosing PTB assess effect clinical sociodemographic factors on time until first contact with or reaching a diagnosis. Methods Retrospective cohort that included active patients...
Introduction: Early reports showed that Omicron (BA.1) SARS-CoV-2 could be less severe. However, the magnitude of risk reduction hospitalization and mortality infections compared with Delta (B.1.617.2) is not yet clear. This study compares severe disease among patients infected variant in Portugal.Methods: We conducted a cohort individuals diagnosed infection between 1st 29th December 2021. Cases were positive PCR test notified to national surveillance system. variants classified first by...
Objetivo: Delinear o perfil epidemiológico dos pacientes diagnosticados com tuberculose na faixa etária pediátrica de 0 a 19 anos no Estado do Pará período 2018 2021 e influência da Covid-19 nessa variável. Métodos: Estudo descritivo transversal, retrospectivo quantitativo realizado partir análise registros ênfase nas variáveis sexo, forma clínica (pulmonar e/ou extrapulmonar) disponíveis Banco Dados Departamento Informática Sistema Único Saúde Brasil (DATASUS). Resultados: A as medidas...
A diabetes mellitus tipo 1 (DM1) é uma doença autoimune mediada por linfócitos T, caracterizada pela destruição progressiva das células beta pancreáticas, levando à deficiência absoluta de insulina. O tratamento convencional baseia-se na administração exógena desse hormônio, sem, no entanto, interferir nos mecanismos imunopatogênicos subjacentes. imunoterapia tem emergido como alternativa promissora, visando modular a resposta imune e preservar função residual beta. Diversas estratégias vêm...
INTRODUÇÃO: A poliomielite, também conhecida como paralisia infantil, é uma doença aguda altamente infecto contagiosa e incurável, capaz de infectar crianças, causada pelo poliovírus. O vírus se localiza na região do trato respiratório dos indivíduos e, devido a especificidade em receptores desses microorganismos, espécie humana seu único hospedeiro. Um cada 200 casos poliomielite evolui para forma paralítica, com deficiências motoras principalmente nos membros inferiores, quadro febril...
Abstract Chagas disease (CD) is a chronic condition associated with high morbidity and mortality in endemic regions of Brazil, particularly the state Bahia. The clinical‐epidemiologic analysis hospital admissions strategic due to limited data on CD infections general lack access diagnosis treatment. This study examines sociodemographic clinical‐epidemiological patterns from its temporal trends 2000 2022 Bahia, Northeast Brazil. A mixed ecological was conducted using information systems. We...

Vaccination strategies to control COVID-19 have been ongoing worldwide since the end of 2020. Understanding their possible effect is key prevent future disease spread. Using a modelling approach, this study intends measure impact Portuguese vaccination strategy on effective reproduction number and explore three scenarios for vaccine effectiveness waning. Namely, no-immunity-loss, 1-year 3-years immunity duration scenarios. We adapted an age-structured SEIR deterministic model used...
Community-acquired pneumonia (CAP) is a major cause of hospitalization that leads to substantial morbidity, mortality, and costs. Evaluating CAP trends over time important understand patterns the impact public health interventions. This study aims describe characteristics in incidence adults hospitalized with Portugal between 2010 2018. In this study, we included data, prevalence comorbidities, population data. hospitalizations (≥18y) living mainland discharged from hospitals were identified...
Context To assess the real impact of human-made structures on bird and bat communities, a significant number carcass-removal trials has been performed worldwide in recent decades. Recently, researchers have started to use camera traps record carcasses exact removal time better understand factors that influence this event. Aims In our study, we endeavoured identify significantly affect carcass-persistence time, such as (1) season, (2) scavenger guild, (3) type carcass, (4) habitat (5) weather...
Abstract Background Accurate data on hypertension is essential to inform decision-making. Hypertension prevalence may be underestimated by population-based surveys due misclassification of health status participants. Therefore, adjustment for bias required when relying self-reports. This study aims quantify in self-reported and ratios the Portuguese component European Health Interview Survey (INS2014), illustrate application multiple imputation (MIME) correction using measured high blood...
An online cross-sectional study on COVID-19 vaccination adhesion was conducted in Portugal nine months after rollout (September-November 2021). Logistic regression used to identify factors associated with hesitancy take the vaccine community-based survey, "COVID-19 Barometer: Social Opinion". Hesitancy 11%; however, of those, 60.5% stated that they intended vaccine. such as lower monthly household income; no intention taking flu this year; perceived reasonable health status; having two or...
Abstract Introduction The B.1.617.2 variant (Delta) was associated with increased transmissibility and lower vaccine effectiveness than the B.1.1.7 (Alpha). However, effect of on disease severity remains unclear. This study aims to assess whether infection a higher risk serious illness, compared other co-circulating variants, measured through hospitalization death by COVID-19 in Portugal. Methods We conducted matched cohort adult individuals diagnosed SARS-CoV-2/COVID-19 between March 29...
Purpose Near real-time vaccine safety surveillance (NRTVSS) is an option for post-licensure assessment. NRTVSS requires timely recording of outcomes in the database used. Our main objective was to examine delays Clinical Practice Research Datalink (CPRD) interest inform feasibility using these data. We also evaluated completeness and further assessed reporting hospitalized events CPRD. Methods selected Guillain–Barré syndrome (GBS), Bell's palsy (BP), optic neuritis (ON) febrile seizures...
Near real-time vaccine safety surveillance (NRTVSS) using electronic health records is increasingly used to rapidly detect signals. NRTVSS has not been fully implemented in the UK. We assessed feasibility of implementing this UK Clinical Practice Research Datalink (CPRD).We selected seasonal influenza vaccine/Guillain-Barré Syndrome (GBS) as an example a rare outcome and measles-mumps-rubella (MMR) vaccine/febrile seizures positive control. For influenza/GBS we system for 2013/2014 2014/2015...
