Parental Involvement and Stress in Children's Quality of Life: A Longitudinal Study with Portuguese Parents during the COVID-19 Pandemic Period

Parental involvement (PI) has particular relevance on children's academic adjustment and on children's general quality of life (QoL). QoL can be influenced by parental stress, specifically the stress suffered during the COVID-19 pandemic. Thus, this study aimed to analyze the differences during the pandemic period (before, after and with no lockdown), comparing these constructs with parental educational level to provide predictors of their children's quality of life. Data collection was performed with a non-probability convenience sampling procedure. It was composed of 129 parents, mainly women (71.8%), with children aged between 6 and 12 years. The family's sociodemographic characteristics were assessed, as well as the PI, parental stress, and children's QoL. The comparison between the three times revealed an increase in the children's QoL, but no differences were found in PI. Based on the parental educational level, as defined by academic qualifications and split into superior and non-superior levels, it is possible conclude that engagement in school activities and parents' meetings increased in the parents with superior education levels and decreased in the parents with lower education levels. This study concluded that despite this difficult and uncertain pandemic period, these parents were able to maintain important aspects of their children's lives.

The Volunteer Functions Inventory (VFI): Adaptation and Psychometric Properties among a Portuguese Sample of Volunteers

The Volunteer Functions Inventory (VFI) is an instrument widely used to assess volunteers' motivation based on the Functionalist Model of Omoto and Snyder. It assesses six factors that reflect several motivational functions. The VFI has been translated into various languages and validated in different cultural contexts, but some studies have reported different factor structures (e.g., five or four factors). In the Portuguese context, previous studies have also shown inconsistent results. The aim of this study was to adapt and validate the VFI for Portuguese volunteers, testing several alternative models (nine models) using confirmatory factor analysis. The sample comprised 468 volunteers (76.3% women), aged from 13 to 81 years (M = 36.66, SD = 14.93). The results support the original interrelated six-factor model as the best-fitting one. The VFI showed good internal consistency and convergent validity. Significant correlations were found between the VFI factors, organizational commitment, and volunteers' satisfaction. Overall, the six-factor VFI is a valid and reliable tool for measuring the motivational functions of Portuguese volunteers, with implications for practice and research in the volunteering field.

Screening for Light Personalities in Portugal: A Cross-Cultural Validation of the Light Triad Scale With an At-risk-of-delinquency Sample

The Light Triad of personality refers to three prosocial personality traits-Faith in Humanity, Humanism, and Kantianism-that promote the worth and dignity of other people, focus on ethical behavior and empathy, and confidence that other people are naturally good. The aim of the present study is to examine the psychometric properties of the Light Triad Scale (LTS)-Portuguese version. Our convenience sample consisted of 242 male and female participants (M = 30.19 years, SD = 12.78, range = 16-77) from Portugal. The proposed latent structure models of the LTS obtained adequate fits. Internal consistency/reliability, as measured by the alpha and omega coefficients, was adequate to good. Construct validity with other psychometric measures (i.e., empathy, dark traits of personality, propensity to morally disengage, and antisociality/criminality measures) and criterion-related validity (with justice involvement variables such as problems with the law, arrested by the police, sentenced to prison and alcohol/drug abuse variables) were demonstrated. Cross-gender measurement invariance was established, with females scoring higher than males. The findings support the use of the LTS as a valid and reliable measure.

Lung cancer survival and sex-specific patterns in Portugal: A population-based analysis

INTRODUCTION

In Portugal, lung cancer (LC) is the first cause of cancer-related death and of death and disability combined. This study aims to analyze the overall survival (OS) and relative survival (RS) of patients diagnosed with LC in 2009-2011 by socio-demographic and tumor characteristics, and analyze sex-specific patterns.

METHODS

We estimated 5-year OS using the Kaplan-Meier method and 5-year net survival through the RS framework. Cox regression modeling was used to determine the hazard ratio (HR) of death associated with each independent variable.

FINDINGS

For the 11,523 cases analyzed, median 5-year OS was 264 days (95% confidence interval [CI]: 254.8-273.2), the cumulative OS was 13.6% and RS was 15.1%. Males had a lower median survival (237 days; 95% CI: 228.2-245.7) compared to females (416 days; 95% CI: 384.4-447.6) (p < 0.0001) and lower 5-year RS proportions (12.1% vs. 24.9%). RS progressively decreased with age (41.7% for age-group <40 to 7.2% for ≥80) and stage (66.6% for stage I to 2.4% for stage IV). As predictors of decreased survival, we identified male gender, increasing age >50, histologic types (squamous cell carcinoma, non-small cell lung cancer not otherwise specified, other unspecified and small cell lung cancer), and increasing stage. Compared to women, the risk of death in men was 37.7% higher (HR = 1.386; 95% CI: 1.295-1.484).

CONCLUSIONS

The differences between OS and RS were small, reflecting the high lethality of LC. Male gender and older age are factors related to poor prognosis. Histology also plays a role in survival prognosis and varies with gender, but the factor related to the worst survival is stage. Although the study reflects data from a decade ago, and major changes occurred in diagnosis, staging and treatment, particularly for advanced disease, as LC mortality is strongly correlated with late stage diagnosis, all efforts should be made to secure early diagnosis and improve survival prospects.

The Dark Side of Multimedia Devices: Negative Consequences for Socioemotional Development in Early Childhood

There is growing concern about the relationship between screen use by young children and negative effects on their development, as children with developmental and socioemotional impairments tend to have difficulties in their relationships and increased academic problems. The aim of our study was to analyse the relationship between the use of multimedia devices and paediatric symptoms in children below 5 years old. Data from 534 Portuguese parents of children aged from 18 to 57 months were collected via a self-report questionnaire. Children's daily exposure to multimedia devices was nearly 2 h per day. Paediatric symptoms were positively associated with watching television and screen time and negatively associated with parents' working hours. Touchscreen use was more frequent among girls and older children. Parents' working hours comprised the most significant predictor of paediatric symptoms. Our findings reinforce past findings on the adverse links between the use of multimedia devices and paediatric symptoms and also highlight the influence of other variables like the child's age and gender, as well as parental factors. The need to both create a more comprehensive framework regarding the long-term effects of multimedia device use and delineate effective strategies for prevention and intervention with parents and children is discussed.

Vulnerability to Suicide Ideation: Comparative Study between Adolescents with and without Psychosocial Risk

Adolescents are characterized as a risk group for suicide, being the fourth leading cause of death in young people. The main aim was to compare vulnerability to suicidal ideation in a sample of young people with and without psychosocial risk. The total sample consisted of 137 adolescents, aged between 10 and 19 years (M = 14.76; SD = 1.40), and it was composed of two groups-the psychosocial risk group (n = 60) and general population group (n = 77). In both groups, suicidal ideation correlated positively with negative events and negatively with self-esteem and social support satisfaction. When comparing the two groups, the psychosocial risk group presented significantly higher mean values of negative life events (mainly separations/losses and physical and sexual abuse) and significantly lower mean values of satisfaction with social support (particularly with family and social activities). It was also found that, in the psychosocial risk group, negative life events were the only significant predictors of suicidal ideation. This study allowed identifying the role of risk and protective factors in suicidal ideation, according to the psychosocial risk of adolescents. The practical implications of the findings on adolescents' mental health and the promotion of their well-being are discussed.

The effect of TB patient delay on loss to follow-up in Portugal

BACKGROUND: Early identification of TB cases, followed by treatment to completion, are essential for controlling and preventing the disease. Previous studies have found some factors associated with both loss to follow-up (LTFU) and patient delay. We aim to build a causal model to investigate the association between TB patient delay and LTFU.METHODS: Pulmonary TB cases were identified using the national surveillance system in Portugal between 2008 and 2017. A directed acyclic graph was used to identify the minimal set of variables to adjust for when studying the association between delay (exposure) and LTFU (outcome). Crude and adjusted hazard were estimated using Cox regression.RESULTS: Nearly 4% of the patients did not follow up treatment. There was no association between patient delay and LTFU, even after adjustment with the minimal set of covariates. Factors associated with a higher risk of LTFU were being younger, being unemployed, living in urban areas, having HIV and the abuse of alcohol and drugs.CONCLUSION: Patient delay was not associated with LTFU, while social conditions were. Future research should investigate the underlying reasons why patients discontinue TB treatment and use these findings to develop targeted interventions that can support patients in completing their treatment regimen.

Tubeless field anaesthesia for surgical removal of an aspirated endoscopy capsule

Capsule endoscopy is a safe, minimally invasive procedure used to investigate gastrointestinal bleeding of unknown origin that persists or recurs after a negative initial endoscopy. The most common adverse effects of capsule endoscopy include abdominal pain, nausea and vomiting. Capsule pulmonary aspiration, although a rare complication, has been reported in the literature. Most reported cases resolve without further medical intervention. In these cases, the capsule is either expelled by coughing, or it re-enters the oropharynx and is then swallowed. In a small number of cases, the capsule remains in the lung, unable to be expectorated. This requires prompt diagnosis and emergency bronchoscopic removal under general anaesthesia. Due to the smooth, rounded surfaces of the capsule, it may be difficult to grasp, and consequently extraction may be technically challenging. The existing literature contains limited documentation on anaesthetic and surgical approaches for managing an aspirated endoscopy capsule. In this case report, we present the management of an aspirated endoscopy capsule in a district general hospital, in which thoracic surgery was not available. Local resources were used to manage this potentially life-threatening complication without patient transfer. In our case, we provided a tubeless field to optimise surgical access. This facilitated the successful surgical extraction of the endoscopy capsule from the left main bronchus.

Examination of the Weinberger Adjustment Inventory-Short Form Among Portuguese Young Adults: Psychometrics and Measurement Invariance

The Weinberger Adjustment Inventory-Short Form (WAI-SF) is a multidimensional measure of behavioral adjustment frequently used with forensic, clinical, and community populations. However, no previous studies have examined the WAI-SF from a more modern psychometric perspective including second-order models, measurement invariance and a better estimation of reliability. The current sample is composed of female and male young adults (N = 610, M = 21.33 years, SD = 3.09, range = 18-37) from a university context in Portugal. Results indicated that both the four-factor intercorrelated and the four-factor second order models of the WAI-SF Distress and Restraint scales showed good fits. The WAI-SF Distress and Restraint scales were negatively and significantly correlated, and the intercorrelations between the subscales of each scale ranged from moderate to high. The WAI-SF scales and subscales mostly showed adequate to good reliability in terms of McDonald's Omega and the more traditional Cronbach's Alpha. Strong cross-gender measurement invariance was demonstrated, with females scoring significantly higher than males on the Anxiety subscale of the Distress scale, and on the Suppression of Aggression, Impulse Control, Consideration of Others, Responsibility subscales, and Restraint scale. The WAI-SF scales and subscales showed distinctive correlates with other measures (e.g., low self-control, psychopathy) and variables (e.g., delinquency seriousness, substance use). Considering our findings, the use of the WAI-SF is recommended among the Portuguese young adult population and its use in criminological research is encouraged.

Epidemiology and outcomes of hospital-acquired bloodstream infections in intensive care unit patients: the EUROBACT-2 international cohort study

PURPOSE

In the critically ill, hospital-acquired bloodstream infections (HA-BSI) are associated with significant mortality. Granular data are required for optimizing management, and developing guidelines and clinical trials.

METHODS

We carried out a prospective international cohort study of adult patients (≥ 18 years of age) with HA-BSI treated in intensive care units (ICUs) between June 2019 and February 2021.

RESULTS

2600 patients from 333 ICUs in 52 countries were included. 78% HA-BSI were ICU-acquired. Median Sequential Organ Failure Assessment (SOFA) score was 8 [IQR 5; 11] at HA-BSI diagnosis. Most frequent sources of infection included pneumonia (26.7%) and intravascular catheters (26.4%). Most frequent pathogens were Gram-negative bacteria (59.0%), predominantly Klebsiella spp. (27.9%), Acinetobacter spp. (20.3%), Escherichia coli (15.8%), and Pseudomonas spp. (14.3%). Carbapenem resistance was present in 37.8%, 84.6%, 7.4%, and 33.2%, respectively. Difficult-to-treat resistance (DTR) was present in 23.5% and pan-drug resistance in 1.5%. Antimicrobial therapy was deemed adequate within 24 h for 51.5%. Antimicrobial resistance was associated with longer delays to adequate antimicrobial therapy. Source control was needed in 52.5% but not achieved in 18.2%. Mortality was 37.1%, and only 16.1% had been discharged alive from hospital by day-28.

CONCLUSIONS

HA-BSI was frequently caused by Gram-negative, carbapenem-resistant and DTR pathogens. Antimicrobial resistance led to delays in adequate antimicrobial therapy. Mortality was high, and at day-28 only a minority of the patients were discharged alive from the hospital. Prevention of antimicrobial resistance and focusing on adequate antimicrobial therapy and source control are important to optimize patient management and outcomes.

The Volunteer Satisfaction Survey (VSS): Adaptation and Psychometric Properties among Portuguese Volunteers

(1) Background: Volunteering satisfaction is one significant construct that nourishes the sustaining of volunteer work, and it is present in reference models such as the three-stage volunteer process model (VPM). The volunteer satisfaction survey (VSS), created by Vecina, Chacón and Sueiro, evaluates three different domains of volunteer satisfaction: specific motivations, organization management and volunteering tasks. The aim of this study was to adapt the instrument and explore the psychometric properties of the 17 items of the VSS in a sample of Portuguese volunteers. (2) Methods: The sample was composed of 335 Portuguese volunteers (aged between 14 and 81 years), mainly women (76.4%). Measures included volunteer satisfaction, work engagement and organizational commitment. (3) Results: The original three-factor model was tested with a confirmatory factor analysis (CFA) and the model fitted the data. Satisfactory levels of internal consistency, discriminant and convergent validity were found. (4) Conclusions: The VSS reveals good psychometric properties and can be considered a useful tool for professionals and future research for volunteers' satisfaction assessment.

Absence among National Health Service workers during the COVID-19 pandemic in Portugal

Background

By March 2020, the first Covid-19 cases were detected in Portugal. While the National Health Service (NHS) faced an increased demand for health care, anecdotal evidence showed that the NHS absenteeism rose. This might be explained by outbreaks in healthcare units, COVID-19 infection due to close contact with patients, self-isolation and quarantines, and family challenges originated by lockdowns. The present work aimed to quantify the absenteeism among NHS workers during the COVID-19 pandemic in Portugal.

Methods

This study used data for the number of NHS workers and absence days (2015-2021), from the Portuguese NHS Transparency Portal and the Strategy and Planning Office. Absenteeism was compared, before and after the pandemic onset, in absolute terms, and as absence rates (number of absent days as a percentage of potential workforce days). Additionally, we performed an interrupted time series analysis, by fitting a Poisson regression model with level change. We controlled for data seasonality using Fourier terms (pairs of sine and cosine functions).

Results

From 2015 until March 2020, the average monthly absence rate was of 12.2, rising to 14.4 in the remaining period. This represented an increase of 18% in the absence rate. The interrupted time series showed an increase of 10.8% in the NHS absenteeism after the pandemic onset [Relative risk =1.10; 95% confidence interval (CI) 1.10-1.11; p &lt; 0.01]. When accounting for seasonality in the data, the model showed an increase of 11.0% in the NHS absenteeism [Relative risk =1.11; 95% CI 1.01-1.22; p &lt; 0.05].

Conclusions

These results highlight the excess of absence days among the NHS workers during the COVID-19 pandemic. In future healthcare crises, health professionals should be protected, by assuring a safe workplace and making protective equipment available. Only then will be possible to reduce constraints in healthcare assistance, guarantee the adequate response, and contain the absence costs.

Key messages

Non-adherence to COVID-19 lockdown: who are they? A cross-sectional study in Portugal

Objectives

The SARS-CoV-2 virus has spread worldwide, leading governments to implement mitigation measures. Understanding the reluctance to adhere to non-pharmacological interventions might help promote adherence to these measures. This study aimed to identify factors associated with non-adherence to the first lockdown in Portugal.

Study design

Cross-sectional study.

Methods

This study used data from a Portuguese community-based survey entitled ‘COVID-19 Barometer: Social Opinion’. Data were collected on risk perception, health status and social experiences using a snowball sampling technique. The event of interest corresponded to participants who reported not staying home during the lockdown period, serving as a proxy for non-adherence to lockdown. Logistic regression was used to identify factors associated with non-adherence to the first lockdown.

Results

Responses from 133,601 individual questionnaires that were completed during the first week of the first lockdown in 2020 were analysed. A minority of participants (5.6%) reported non-adherence to lockdown (i.e. leaving home for reasons other than essential situations). Working in the workplace was the factor with the strongest association of non-adherence to the lockdown. Several other factors were also associated with non-adherence to the first lockdown; namely, being a man, being a student, having a low level of education, having a low income, living alone or with a high-infection-risk professional (e.g. doctor, nurse, pharmaceutical, health technician, firefighter, police officer, military, essential services worker), perceiving the risk of getting COVID-19 to be high, not having social support in case of infection, feeling agitated, sad or anxious every day, and considering the preventive measures to be unimportant or inadequate.

Conclusions

Non-adherence to lockdown was associated with socio-economic, trust and perception factors. Future research should investigate the mechanisms underlying these associations to help identify the population groups who are most at risk of non-adherence.

Dark Triad Psychopathy Outperforms Self-Control in Predicting Antisocial Outcomes: A Structural Equation Modeling Approach

Dark Triad traits and self-control are considered viable causal precursors to antisocial and criminal outcomes in youth. The purpose of the present study is to concurrently compare how Dark Triad traits and self-control differ in terms of predicting self-reported juvenile delinquency, CD symptoms, proactive overt aggression, and crime seriousness. The sample consisted of 567 (M = 15.91 years, SD = 0.99 years, age range = 14–18 years) Southern European youth from Portugal. Structural-equation-modelling procedures revealed that the psychopathy factor of Dark Triad traits presented the strongest significant hypothetical causal associations with the antisocial/criminal outcomes, followed by self-control. Machiavellianism and narcissism presented the lowest causal associations. Our findings indicate that psychopathy, as operationalized in the Dark Triad, concurrently surpasses self-control and the remaining factors of the Dark Triad in terms of predicting antisocial/criminal outcomes in youth. This suggests that behavioral disinhibition, or a core incapacity to regulate one’s conduct, is central for understanding delinquency and externalizing psychopathology. Comparatively, the interpersonal component of dark personality features, such as Machiavellianism and narcissism, are secondary for understanding crime.

Emotional Availability in Mother-Child and Father-Child Interactions as Predictors of Child's Attachment Representations in Adoptive Families

Emotional availability (EA) in parent-child interactions is associated with positive child outcomes, including attachment security. However, little is known about EA in adoptive families. This study investigated the associations between secure representations of attachment in adopted children and the adoptive parents' EA. The participants (n = 75) included 26 mothers, 23 fathers, and 26 children who were aged 3 to 9 years. Children completed the Attachment Story Completion Task. Adult-child dyadic relationships were assessed using the EA^® System. The results showed that the children's and parents' EA, age when adopted, and time elapsed since adoption were associated with more secure children's attachment representations. Implications for family support and public policy are discussed.

Impact of an Online Parenting Support Programme on Children’s Quality of Life

The study aims to describe the parental use of an online parenting support programme, the ‘Open Window to Family’ (JAF) and to evaluate its impact on perceived children’s quality of life (QoL). This programme makes online resources available to support positive parenting. The study included 363 parents (nintervention group = 142) who completed measures to evaluate their children’s QoL. The results suggest that using the programme for a longer time and accessing more information/services are positively related to the perception of utility but not to the frequency of use. The programme proved to be more useful for specific difficulties and to search for specific information. We found high levels of parental perception of children’s well-being, both physical and psychological, and lower values in social support and relationships with peers. No differences were observed between the total QoL of children in the intervention group and control group. The differences in the dimensions of QoL are due to interaction with the level of education of the mother: mothers with higher education reported higher physical well-being, social support, relationships with peers, and school context. Guidelines are suggested to enhance the accessibility of this type of programme as well as enhance its impact on parents and children.

Prospective international validation of the predisposition, infection, response and organ dysfunction (PIRO) clinical staging system among intensive care and general ward patients

Background

Stratifying patients with sepsis was the basis of the predisposition, infection, response and organ dysfunction (PIRO) concept, an attempt to resolve the heterogeneity in treatment response. The purpose of this study is to perform an independent validation of the PIRO staging system in an international cohort and explore its utility in the identification of patients in whom time to antibiotic treatment is particularly important.

Methods

Prospective international cohort study, conducted over a 6-month period in five Portuguese hospitals and one Australian institution. All consecutive adult patients admitted to selected wards or the intensive care, with infections that met the CDC criteria for lower respiratory tract, urinary, intra-abdominal and bloodstream infections were included.

Results

There were 1638 patients included in the study. Patients who died in hospital presented with a higher PIRO score (10 ± 3 vs 8 ± 4, p < 0.001). The observed mortality was 3%, 15%, 24% and 34% in stage I, II, III and IV, respectively, which was within the predicted intervals of the original model, except for stage IV patients that presented a lower mortality. The hospital survival rate was 84%. The application of the PIRO staging system to the validation cohort resulted in a positive predictive value of 97% for stage I, 91% for stage II, 85% for stage III and 66% for stage IV. The area under the receiver operating characteristics curve (AUROC) was 0.75 for the all cohort and 0.70 if only patients with bacteremia were considered. Patients in stage III and IV who did not have antibiotic therapy administered within the desired time frame had higher mortality rate than those who have timely administration of antibiotic.

Conclusions

To our knowledge, this is the first external validation of this PIRO staging system and it performed well on different patient wards within the hospital and in different types of hospitals. Future studies could apply the PIRO system to decision-making about specific therapeutic interventions and enrollment in clinical trials based on disease stage.

Patient and healthcare delays in critical and non-critical pulmonary tuberculosis incidence areas in Portugal: are there differences?

OBJECTIVES

To characterize patient, healthcare, and total delay in diagnosing pulmonary tuberculosis (PTB) in critical (higher PTB incidence) and non-critical (lower PTB incidence) areas and their determinants considering clinical and sociodemographic factors.

STUDY DESIGN

Retrospective cohort study.

METHODS

Data was retrieved from the Portuguese National Tuberculosis Surveillance System (SVIG-TB). Were included in the study all active PTB patients (n = 11,762) notified between 2008 and 2017. Spatial analysis was used to define critical and non-critical areas. Kaplan-Meier estimator, logrank test, and Cox regression were conducted, stratified by area.

RESULTS

PTB cases in critical areas (n = 6594, 56.1%) presented longer patient median delay (41 vs 31days), shorter healthcare median delay (7 vs 10 days), and longer total median delay (63 vs 61days) t.han non-critical areas. Patient and total delay increased in both areas over time, while healthcare delay only increased in non-critical areas. Icn both areas, being from a high TB incidence country and alcohol abuse were associated with longer patient delays. Being female, older age, and oncologic diseases were associated with longer healthcare delays. Respiratory diseases were only associated with a longer healthcare delay in non-critical areas. Being female, older, and from a high TB incidence country were associated with a longer total delay in both areas.

CONCLUSIONS

Patient delay was significantly longer in critical areas, and healthcare delay was significantly longer in non-critical areas. Several factors associated with longer delays have been identified, most of which are shared by critical and non-critical areas. Differences in patient and healthcare delay, for example, by sex, age, or country of birth, highlight the need for targeted public health interventions to help reduce these differences.

Factors associated with motivation to avoid meeting family and friends during the COVID-19 pandemic

Background

The widespread adherence to behaviours that prevent the transmission of the SARS-CoV-2 virus depends on human will. There is a paucity of research on the factors that influence adherence to social distancing. Available research suggests that it varies with the specific behaviour and that reducing contact with family and friends is the hardest one. This study aims to identify factors associated with motivation to avoid meeting with family and friends during the second lockdown of the COVID-19 pandemic in Portugal.

Methods

We used data from a community-based survey, “COVID-19 Barometer: Social Opinion”, which includes sociodemographics, psychosocial variables, and subjective health and wellbeing indicators from 20th February to 19th March 2021. We included 1336 participants who answered the question “To what extent is it easy for you to avoid visiting family and friends?”. Logistic regression analysis was used to identify factors associated with difficulty to avoid visiting family and friends.

Results

Preliminary data shows that 38.4% (513) had difficulties avoiding meeting with family and friends. Those with greater difficulty were the ones who have less education, higher negative emotionality, do not work remotely, have more difficulties to stay home and practice physical distancing and consider the Government's measures inadequate. Contrarily, those who have less difficulty avoiding visiting friends and family are older and have low risk perception of COVID-19 infection.

Conclusions

This study suggests higher difficulty in avoiding visiting friends and family for those whose routines demand not staying at home, with low agreement with Government measures, and struggle with higher negative emotionality, confirming the personal costs of these behaviours and the importance of habits. Older people had less difficulty, suggesting that these measures may be closer to their usual routines. Interventions should consider the specificities of social interaction.

Key messages

Social distancing comes at an enormous cost to people's livelihoods and it also depends on people living circumstances.

Interventions to improve adherence to social distancing should consider the specificity of social interaction and the potential dissonance created by the overall routines.

Healthcare system delay and utilization in tuberculosis patients in Portuguese high-incidence region

Background

In Portugal, the Tâmega e Sousa region (TeS) has a high incidence of tuberculosis (TB) [27.4 and 43.8 per 100.000 inhabitants in sub-regions Baixo Tâmega (BxT) and Vale do Sousa Sul (VSS), 2017]. Delay in TB diagnosis leads to increased transmission, which may lead to more people infected. This study aimed to describe healthcare system delay among TB patients and healthcare utilization from symptoms onset to diagnosis in TeS.

Methods

We analysed pulmonary TB cases notified in BxT and VSS in 2014-7 in the national surveillance system (SVIG-TB). Concomitantly, we analysed healthcare utilisation from patients in a retrospective study (URBAN-TB) about TB delays in 2019-20. We characterised demographics of patients from each data source and comorbidities from SVIG-TB. We calculated median overall delay until diagnosis (days); and healthcare delay overall and by patient characteristics, for each sub-region. Delay was calculated only when relevant dates were recorded. Healthcare utilisation from symptoms onset to diagnosis was described using the frequency of each first contact provider and the average number of visits until diagnosis.

Results

Included 139 patients from BxT and 206 from VSS (83% male, 53% aged 40-59y, and 17% with silicosis). Global delays were 48 and 75 days (n = 57/132; BxT and VSS). Healthcare delays were 7 and 8 days (n = 76/180; BxT and VSS). In both ACES, healthcare delays were longer for patients aged 60-79y, with COPD and aged 0-19y. Healthcare utilisation analysis included 38 patients (89% male; 55% aged 40-59y; n = 17/21). Primary care (n = 15; 39%) and emergency department (ED) (n = 9; 24%) were frequent points of first contact. The average number of visits until diagnosis was higher for patients from ED (3.9) and lower for patients from TB specialised units (1.3).

Conclusions

Our results suggest that in TeS it is important to avoid ED as a point of first contact of TB patients and to facilitate the diagnosis in young, older and COPD patients.

Key messages

Emergency department is a relevant point of first contact and may be included in efforts to reduce tuberculosis delay. Policies to reduce tuberculosis delay may target younger, older and COPD patients.

Factors associated with avoidance of emergency department visits in Portugal during the pandemic

Background

Avoiding an emergency department (ED) visit risks irreversible negative consequences for patients' health. EDs are a frequent access point to the Portuguese health system. Previous studies have shown that patients may avoid visiting ED during the pandemic. This study aims to identify factors associated with avoidance of ED visits in Portugal during the COVID-19 pandemic.

Methods

We used data from a community-based survey, “COVID-19 Barometer: Social Opinion”, which includes healthcare utilisation, health status, and risk perception in Portugal from 11th April 2020 to 16th April 2021. We included respondents that reported having needed ED care. Data were collected on sociodemographics, health status (comorbidities, mental health), risk perception (COVID-19 and complications), level of trust in health services and self-assessment of the severity of the reason for ED visit. The outcome of interest was the decision to avoid ED care. We used logistic regression to identify factors associated with the decision to avoid ED.

Results

Preliminary data showed that 914 respondents reported needing ED care (74.8% female; mean age 43 years). From those, 224 (25%) decided to avoid ED care. ED visits avoidance was higher during lockdowns (28%). People reporting specific comorbidities (cardiac, autoimmune, respiratory) avoided ED more than those without them. Perception of no severe reason for ED visit, poor mental health, perception of higher risk of COVID-19 and complications, and low trust in health services response to the pandemic were associated with higher odds of ED visit avoidance.

Conclusions

People avoiding ED visits represented a considerable share. The decision to avoid ED visit was associated with clinical characteristics, but the perception of risk and assessment of the context and health system response also played a role in decision making.

Key messages

The effect of avoided ED visits on health should be a research and policy concern. People with certain comorbidities or perception of high risk of COVID-19 and complications may be closely monitored.

The impact of age when screening for latent tuberculosis infection - is it a problem?

Background

Older population in developed countries represents a large reservoir of tuberculosis (TB) infection. Knowledge if age can contribute to false negative results in the immunological tests available for screening latent TB infections (LTBI) is critical to improve their usefulness in Public Health strategies for TB control. The aim of this study was to ascertain whether age was a risk factor for false negative (FN) results in the tuberculin skin test (TST) and in an interferon gamma release assay (IGRA).

Methods

Retrospective cohort study carried out using data from the Portuguese National Tuberculosis Surveillance system (2008-2015). Were included all active pulmonary TB cases with an IGRA (n = 597) and/or TST (n = 6185) result. TST outcomes were interpreted using a 5mm (TST-5mm) and 10mm (TST-10mm) cutoff. Logistic regression analysis crude and sex-adjusted was used to evaluate the association of age to the risk of FN results.

Results

Patients with a TST result presented a mean age of 42.7 years and patients with an IGRA result presented a median age of 45.5 years. TST-5mm, TST-10mm and IGRA had 36.5%, 43.9% and 24.5% FN results, respectively. Older patients presented a statistically significant association with the risk of FN TST results, regardless of using a 5mm [71-80years: OR 2.209; &gt;80years: OR 2.491; p &lt; 0.001] or 10mm [71-80years: OR 1.986; &gt;80years: OR 2.308; p &lt; 0.001] cut-off. Age was not a predictive factor for FN IGRA results. However, older patients presented a significant association with indeterminate IGRA results [71-80years: OR 3.808; &gt;80years: OR 5.214; p &lt; 0.001].

Conclusions

When using TST as part of the Public Health strategies for screening elderly patients, healthcare professionals should bear in mind that there is an increased risk of obtaining a FN result. On the other hand, age did not show an association with the occurrence of FN IGRA results, which suggests that this test could perform better when screening for LTBI in older patients.

Key messages

TST in elderly people is associated with false negative results thus, when using this test for screening for LTBI, a negative result should be interpreted with caution. IGRA was not associated with false negative results in elderly people, however indeterminate results can occur more frequently, thus performing better in this population group.

Space-time analysis of pulmonary tuberculosis hospitalizations in mainland Portugal (2002-2016)

Background

Tuberculosis (TB) imposes a great pressure on healthcare resources, particularly in terms of hospital-based treatment and extended hospitalization. Understanding the space-time clustering of pulmonary TB (PTB) hospitalizations leads to a richer knowledge to assist decision makers in Public Health to develop strategic interventions to reduce these hospitalizations. Our objective was to identify space-time clusters of PTB hospitalizations at municipality level in mainland Portugal.

Methods

Ecologic study using data from nationwide hospitalization database of Portugal. All patients with a diagnosis of PTB (primary or secondary) and reference to place of residence were included in the study (n = 22760). Space-time analysis was used to define clusters with high rates of hospitalizations at the municipality level between 2002 and 2016.

Results

Overall hospitalization rate was 17.7/105population/year, with hospitalization rates decreasing by 64.9% during this period (2002:29.4/105; 2016:9.6/105). Space-time analysis of the overall period identified five different clusters, with the clusters in Lisboa and Porto metropolitan areas presenting the highest hospitalization rates (51.5/105 and 43.6/105population, respectively). In a more recent period (2011-2016), were identified four clusters with Lisboa metropolitan area and a northeast rural region presenting the highest hospitalization rates (27.6/105 and 46.2/105population, respectively).

Conclusions

PTB hospitalization rates in continental Portugal presented a constant decrease between 2002 and 2016. We identified a cluster of PTB hospitalizations in a rural region of northeast mainland Portugal, an area where the incidence of TB is below 20/105population. A closer look is needed to understand the reasons behind this high number of hospitalizations. Our results show that space-time analysis can be a resource to monitor the dynamic of the disease and identify possible areas needing Public Health intervention.

Key messages

Pulmonary tuberculosis hospitalizations are decreasing in mainland Portugal, with the two major urban areas (Lisboa and Porto) presenting the clusters with highest hospitalization rates. A cluster of hospitalizations for pulmonary tuberculosis was identified in a rural region in the northeast of mainland Portugal, an area with a low incidence of tuberculosis.

Identification of hospitalized patients with community-acquired infection in whom treatment guidelines do not apply: a validated model

OBJECTIVES

To develop and validate a clinical model to identify patients admitted to hospital with community-acquired infection (CAI) caused by pathogens resistant to antimicrobials recommended in current CAI treatment guidelines.

METHODS

International prospective cohort study of consecutive patients admitted with bacterial infection. Logistic regression was used to associate risk factors with infection by a resistant organism. The final model was validated in an independent cohort.

RESULTS

There were 527 patients in the derivation and 89 in the validation cohort. Independent risk factors identified were: atherosclerosis with functional impairment (Karnofsky index <70) [adjusted OR (aOR) (95% CI) = 2.19 (1.41-3.40)]; previous invasive procedures [adjusted OR (95% CI) = 1.98 (1.28-3.05)]; previous colonization with an MDR organism (MDRO) [aOR (95% CI) = 2.67 (1.48-4.81)]; and previous antimicrobial therapy [aOR (95% CI) = 2.81 (1.81-4.38)]. The area under the receiver operating characteristics (AU-ROC) curve (95% CI) for the final model was 0.75 (0.70-0.79). For a predicted probability ≥22% the sensitivity of the model was 82%, with a negative predictive value of 85%. In the validation cohort the sensitivity of the model was 96%. Using this model, unnecessary broad-spectrum therapy would be recommended in 30% of cases whereas undertreatment would occur in only 6% of cases.

CONCLUSIONS

For patients hospitalized with CAI and none of the following risk factors: atherosclerosis with functional impairment; previous invasive procedures; antimicrobial therapy; or MDRO colonization, CAI guidelines can safely be applied. Whereas, for those with some of these risk factors, particularly if more than one, alternative antimicrobial regimens should be considered.

Early Cerebrovascular Ultrasonography as a Predictor of Hemorrhagic Transformation After Thrombectomy

OBJECTIVES

To determine the predictive value of early transcranial color-coded sonography (TCCS) for intracranial hemorrhage (ICH) in patients with large artery occlusion (LAO) stroke of carotid circulation, who were submitted to endovascular therapy (EVT) with successful reperfusion.

MATERIALS AND METHODS

Retrospective study evaluating a cohort of consecutive stroke patients with LAO of the carotid circulation that were recanalyzed with EVT. We measured angle-corrected peak systolic velocities, end-diastolic velocities and mean flow velocities (PSV, EDV and MFV) of the symptomatic and asymptomatic middle cerebral artery (MCA). The ratio between MFV of the symptomatic MCA and MFV of the asymptomatic MCA (MCA-Ra) was calculated. Parenchymal hematoma in the 24 hours control CT was considered as ICH. Univariate associations and multivariate analyses were used to identify early independent predictors for ICH among TCCS findings.

RESULTS

We included 234 patients, mean age 72.5 (SD 12.6) years, 52.1% male. The mean time between recanalization and TCCS was 12.3 hours (range 3-22). Patients who developed postinterventional ICH showed a higher MCA-Ra (1.02 ± 0.26 vs 1.16 ± 0,21, p = 0.036). In multivariate analysis, only higher MCA-Ra remained independently associated with postinterventional ICH (OR: 6.778, 95%CI: 1.152-39.892, p = 0.034). A value of MCA-Ra ≥ 1,05 was associated with ICH, showing a sensitivity of 81.3% and a specificity of 65.9%; the AUC based of the ROC analysis was 0.688 (95% CI 0.570-0.806).

CONCLUSION

TCCS performed within the first 24 hours after stroke onset can help to predict hemorrhagic transformation in patients with LAO.

The Brief COPE: Measurement Invariance and Psychometric Properties among Community and At-Risk Portuguese Parents

Parenting generally brings about high internal and external demands, which can be perceived as stressful when they exceed families’ resources. When faced with such stressors, parents need to deploy several adaptive strategies to successfully overcome these challenges. One of such strategies is coping, an important cognitive and behavioural skill. In this study, we intended to examine the psychometric properties of Carver’s (1997) Brief COPE (Coping Orientation to Problems Experienced), extending its cross-cultural validity among a Portuguese sample of community and at-risk parents. The sample comprised community (n = 153) and at-risk (n = 116) parents who completed the brief COPE, the Family Adaptability and Cohesion Scales and the Parenting Stress Index—Short Form. Confirmatory factor analysis, internal consistency, cross sample invariance, convergent and discriminant validity were analysed. Data from the confirmatory factor analysis revealed that the 14-factor model obtained the best fit. The results provided evidence that the Brief COPE is a psychometrically sound instrument that shows measurement invariance across samples and good reliability. Our findings demonstrated that the Portuguese version of brief COPE is a useful, time-efficient tool for both practitioners and researchers who need to assess coping strategies, a relevant construct in family context.

Teaching young consumers in Europe: a multicentre qualitative needs assessment with educators on food hygiene and food safety

AIM

Foodborne illnesses have a significant global burden and can be life-threatening, with higher risk in vulnerable groups such as children. SafeConsume is an EU-funded, transdisciplinary project aiming to improve consumers' food safety behaviour. Developing educational resources on food safety for use in schools has potential to improve teaching of our young consumers. The aim of this study was to explore school educators' attitudes, behaviours and knowledge towards food hygiene, safety and education.

METHODS

Focus groups and interviews in England, France, Portugal and Hungary explored educator knowledge, skills, intentions and beliefs around educating young people (11-18 years) about food safety. Data were analysed using NVivo and emerging themes were applied to the Theoretical Domains Framework.

RESULTS

A total of 48 educators participated. Knowledge, confidence and skills to teach food safety to young people varied depending on background and training. Educators reported they had a role to teach food safety to young people, were positive about delivering education and optimistic they could improve students' food safety behaviour. Barriers to teaching included lack of national curriculum coverage, limited time and money, and lack of facilities. Educators reported that social influences (family, celebrity chefs, public health campaigns and social media) were important opportunities to improve young peoples' awareness of food safety and consequences of foodborne illness.

CONCLUSION

Educator food safety expertise varied; training could help to optimise educator knowledge, confidence and skills. Ministries of Health and Education need encouragement to get food safety incorporated further into school curricula across Europe, so schools will be motivated to prioritise these topics.

Targeted nanostructured lipid carriers for doxorubicin oral delivery

The treatment with anticancer drugs remains a challenge, as available drugs still entail the risk of deleterious off-target effects. The present study describes folic acid conjugated nanostructured lipid carriers (NLCs) as an effective doxorubicin delivery approach targeted to breast cancer cells. Two distinct NLCs formulations were designed and optimized leading to an encapsulation efficiency over than 65%. Cytotoxic and targeting potential of NLCs were studied in vitro, using MDA-MB-231 cell line. Results showed an enhanced cellular uptake of conjugated NLCs. In vitro release studies, mimicking the path in the body after oral administration, show that all formulations would reach the tumor microenvironment bearing 50% of the encapsulated doxorubicin. Moreover, NLCs demonstrated storage stability at 25 °C for at least 42 days. Overall, results revealed that the developed NLCs enable the possibility of oral administration and are a promising approach for the targeted delivery of doxorubicin to breast cancer cells.

Anti-Zika virus activity of several abietane-type ferruginol analogues

Abietane diterpenoids are naturally occurring plant metabolites with a broad spectrum of biological effects including antibacterial, antileishmanial, antitumor, antioxidant, as well as antiinflammatory activities. Recently, we found that some analogues of natural ferruginol ( 2 ) actively inhibited dengue virus 2 (DENV-2) replication. Due to the similarity with DENV, we envisaged that abietane diterpenoids would also be active against Zika virus (ZIKV). Six selected semi-synthetic abietane derivatives of (+)-dehydroabietylamine ( 3 ) were tested. Cytotoxicity was determined by MTT assay in Vero cells. In vitro anti-ZIKV (clinical isolate, IMT17) activity was evaluated by plaque assay. Interestingly, these molecules showed potential as anti-ZIKV agents, with EC₅₀ values ranging from 0.67 to 18.57 µM, and cytotoxicity (CC₅₀ values) from 2.56 to 35.09 µM. The 18-Oxoferruginol (8) (EC₅₀ = 2.60 µM, SI = 13.51) and 12-nitro-N-benzoyldehydroabietylamine (9) (EC₅₀= 0.67 µM, SI = 3.82) were the most active compounds, followed by 12-hydroxy-N-tosyldehydroabietylamine ( 7 ) (EC₅₀ = 3.58 µM, SI = 3.20) and 12-hydroxy-N,N-phthaloyldehydroabietylamine ( 5 ) (EC₅₀ = 7.76 µM, SI = 1.23). To the best of our knowledge, this is the first report on anti-Zika virus properties of abietanes.

Benefits and damages of the use of touchscreen devices for the development and behavior of children under 5 years old-a systematic review

AIM

Several health organizations have been expressing concern about the amount of time children spend using electronic devices and about the benefits and damages of the use of touchscreen devices, such as smartphones or tablets, for the development and behavior of children under the age of 5. A systematic review was carried out in order to understand the impact of touchscreen device usage toward children's development and behavior under the age of 5.

METHODS

Using the PRISMA method, from a total of 6314 studies found in online databases, searched in English, between 01/01/2000 and 01/10/2018, 11 studies were selected for analysis.

RESULTS

The results revealed that, in children under the age of 5, the damages of the use of touchscreen devices are superior to the benefits that may result, especially when there are more hours of screen time. More importance is given to the quality of the child-adult relationship and not to the use of touchscreen devices. Nevertheless, some studies emphasize some aspects that may reduce the negative effects, such as moderate use, less screen time, parental monitoring, and viewing educational programs in an academic environment.

CONCLUSIONS

Guidelines that should be given to parents about the use of touchscreen devices by children are discussed. The limitation of this study was the difficulty in finding studies directed to the desired age and type of electronic device. This may be taken as a potential cause of bias.

Tuberculosis among immigrants: risk factors associated with a delayed diagnosis in Portugal

Background

A timely diagnosis is a key factor to TB control, since delayed diagnosis increases transmission, severity and mortality rates. However, immigrants have a higher risk of delay due to difficulties in the access to the healthcare services. Hence, the aim of this study is to identify risk factors associated with delays in immigrants and compare the results with the national population.

Methods

We carried out a retrospective study to analyse all pulmonary TB cases notified in Portugal having a passive case finding, between 2008 and 2017. Global delay was defined as the number of days between symptoms onset and diagnosis date and divided into patient delay (time between symptoms onset and first appointment date) and healthcare services delay (time between first appointment date and diagnosis date). A descriptive analysis was performed, and factors associated with each delay were identified using a Cox regression. Analyses were stratified by country of origin: immigrants (born outside of Portugal) and nationals (Portuguese population).

Results

Our results were consistent with previous studies and showed that the immigrant population was younger, had a higher proportion of HIV infection and had a smaller proportion of alcoholics, drug addicts, inmates, homeless and individuals living in community residencies compared to nationals. Immigrants had higher patient delay (44 vs. 36 days) compared to nationals. Different risk factors were associated with the delay in immigrants and nationals. Alcohol addiction was the only significant variable in both populations and was associated with lower delay in health services.

Conclusions

Immigrants have higher global delay, attributable to a higher patient delay. The risk factors related to TB diagnosis delay have an heterogeneous association in immigrant and nationals. Hence, tailored interventions should be implemented to decrease the delay among immigrants.

Key messages

Different risk factors were identified for the patient and healthcare services delay among immigrants and nationals, which highlight the importance to analyse each component of TB diagnosis delay. Immigrants have higher patient delay compared to nationals, hence tailored interventions should be implemented to facilitate access to healthcare services in this population.

Factors related to tuberculosis delays: Evidence from nationwide retrospective study in Portugal

Background

Globally, tuberculosis (TB) remains one of the top 10 causes of deaths and the leading cause from a single infectious agent. Delayed TB diagnosis and/or treatment may result in the transmission of bacilli, increasing infectivity, the risk of severe disease states, morbidity and mortality. It is essential to identify the factors that prolong delays in TB services so that health planners can initiate necessary measures to control TB infections.

Methods

A nationwide retrospective study was conducted from 2010 until 2013 to analyze tuberculosis delays under the setting of the Portuguese National Tuberculosis Control Programme. There were 16824 participants who were from 25 administrative districts under 7 regions and were originated from 70 countries in the world. The log-rank test, Cox's regression, and the Kaplan-Meier method have employed to analyze TB delay data.

Results

The median of patients` delay was 34 days with interquartile ranges (IQR) 50 days. Alcohol addicted people with TB infection were delayed by 40 days with 95% CI 37.73-42.28 whereas the non-addicted people took 33 days with 95% CI 32.35-33.65. The median diagnostic delay was 12 days with an IQR of 38 days. The female participants were delayed more than that of male (median delay for female 17 days with 95% CI 15.80-18.19) in TB diagnosis. Further, comorbidities e.g. lung cancer affected TB candidates were delayed more than their counterparts (median delay 37 days with 95% CI 23.29-50.70). The median of public health delays was 63 days with IQR 72 days. The females were delayed more than that of males (median delay 68 days with 95% CI 66.06-69.94). The adjusted Cox's regression identifies the features - older age, female, drug addiction, and community residence as potential factors that might affect TB delays.

Conclusions

It is essential to emphasize on the influencing dynamics - older age, female patients, HIV patients, alcohol addiction, and comorbidities to minimize TB delays.

Key messages

To minimize spreading risk of TB infections the dynamics of TB delays e.g. older age, female patients, drug, and alcohol addiction, comorbidities should be prioritized in the TB control programs. Special attention should be given to other lung diseases while diagnosing TB infections.

Heat waves and mortality: developing a local prediction model based on two kinds of heat waves

Background

Heat waves (HW) will tend to have a higher impact on mortality due to climate change. The aim of this study was to develop a tailored model to predict local mortality associated to HW.

Methods

In this ecological study, daily temperature and daily mortality were collected from May to October of 1980 to 2017 in Coimbra, Portugal. Two definitions of HW were used: more than two consecutive days of maximum temperature (MaxT) or minimum temperature (MinT) above percentile 95 for the periods in question. Attributable general mortalities with 13 and 30 lag days were calculated and then converted to attributable general mortality rates adjusted to the resident population. Bivariate and multivariate analyses with SPSS statistics were performed with the following independent variables for each HW: MaxT, diurnal temperature variation (DTV), mean of the mean daily temperatures, month, ageing index (AI), ordinal number of the HW for that year (ONHW), duration, overlapping of another HW and existence of a public health contingency plan.

Results

The multivariate analyses returned a R2=0,19 for the MaxT model (MaxTM) for both 13 and 30 lag days and a R2=0,51 for the MinT model (MinTM) with 13 lag days and R2=0,45 for 30 lag days. DTV was the only variable with statistical significance in the MaxTM (p &lt; 0,023; β = 0,44 for 13 lag days and p &lt; 0,024; β = 0,43 for 30 lag days). In the MinTM model two variables had statistical significance: AI (p &lt; 0,008; β = 1,72 for 13 lag days and p &lt; 0,037; β = 0,44 for 30 lag days) and ONHW (p &lt; 0,038; β= -0,44 for 30 lag days).

Conclusions

MaxTM and MinTM had different predictability potentials with different statistical significant independent variables. This may mean HW defined by MaxT have impact in a distinct way from HW defined by MinT. Further development of these models that include acclimatization indexes and causes of mortality may help local public health services to create more efficient, selective contingency plans.

Key messages

Minimum and maximum temperature defined heat waves may impact mortality differently. Local heat wave/mortality models may contribute to more efficient, selective contingency plans than regional models.

Delays in the diagnosis of pulmonary tuberculosis in critical and non-critical areas in Portugal

Background

Delays in diagnosing tuberculosis lead to longer infectious periods, posing a challenge in tuberculosis control. This is particularly relevant in high incidence areas (critical). Thus, the objectives of this work were to characterize tuberculosis diagnosis delay and its components (patient delay and health delay) in incidence critical and non-critical areas in Portugal, as well as associated factors.

Methods

Notified cases of pulmonary tuberculosis diagnosed due to symptoms (passive screening) in the Portuguese Tuberculosis Surveillance System were analysed (2008-2017). Patient, health and overall delays were calculated. Factors associated with each delays' components were identified utilising Cox regression, while adjusting for sex, age and education level. Analyses were stratified by area type (critical and non-critical).

Results

Median (1st-3rd quartile - Q1-Q3) delays in patient, health and overall delay in critical areas were: 40 (Q1-Q3: 21-76), 8 (Q1-Q3:1-31), and 65 (Q1-Q3: 40-105) days, respectively; similar delays in non-critical areas were 32 (Q1-Q3:16-63); 9 (Q1-Q3: 1-34) and 58 (Q1-Q3: 35-98), respectively. More recent cases, adults younger than 65 years and alcoholic presented longer patient delays (both areas); healthcare professionals and patients with HIV infection presented shorter patient delays (only critical areas). Tuberculosis high-risk groups (males, alcohol dependency, homelessness, community residency) presented shorter health delays in both areas; drug use also presented shorter health delays but only in critical areas. Existing comorbidities was associated with longer health delays in both areas.

Conclusions

Patient delays increased between 2008 and 2017. Groups with longer/shorter delays differed between delay type and area type. Intervening in tuberculosis diagnosis delays requires different action for critical and non-critical areas, targeting health literacy from the general population and training of healthcare professionals.

Key messages

Delays in diagnosing in Portugal are mainly driven by delays in patient seeking care and are longer in areas of higher tuberculosis incidence. Intervening in tuberculosis diagnosis delays in Portugal requires different action in different areas, targeting health literacy in the general population and training of professionals.

Burden of disease associated with dietary exposure to carcinogenic aflatoxins in Portugal using human biomonitoring approach

Human biomonitoring is an important tool to assess human exposure to chemicals, contributing to describe trends of exposure over time and to identify population groups that could be under risk. Aflatoxins are genotoxic and carcinogenic food contaminants causing hepatocellular carcinoma, the third leading cause of cancer deaths worldwide. In Portugal, scarce data are available regarding exposure to aflatoxins and no previous study used human biomonitoring data to comprehensively characterize the associated burden of disease. 24 h urine and first-morning urine paired samples were collected by 94 participants and were analyzed by liquid chromatography-tandem mass spectrometry for the quantitative determination of aflatoxins (B₁, B₂, G₁, G₂ and M₁). Deterministic and probabilistic models were developed to assess the Portuguese exposure to aflatoxins and to estimate the health impact of this exposure, estimating the attributed Disability-Adjusted Life Years (DALYs). Aflatoxins were detected in a maximum of 13% (AFB₁), 16% (AFB₂), 1% (AFG₁), 2% (AFG₂) and 19% (AFM₁) of the urine samples. Data obtained through the probabilistic approach revealed an estimated mean probable daily intake of 13.43 ng/kg body weight per day resulting in 0.13 extra cases of hepatocellular carcinoma, corresponding to mean annual DALYs of 172.8 for the Portuguese population (10291027 inhabitants). The present study generated for the first time and within a human biomonitoring study, reliable and crucial data to characterize the burden associated to the exposure to aflatoxins of the Portuguese population. The obtained results constitute an imperative support to risk managers in the establishment of preventive policy measures that contribute to ensure public health protection.

Burden of disease attributable to exposure to aflatoxins in Portugal using Human biomonitoring data

Key messages

Portuguese population is exposed to aflatoxins, chemical food contaminants that may be harmful (carcinogenic, immunotoxic, mutagenic, teratogenic, hepatotoxic) to humans. Human biomonitoring studies provide realistic data on internal exposure at individual level, contributing to a more accurate estimation of the burden derived from this exposure.

Risk assessment of Portuguese population to multiple mycotoxins: the human biomonitoring approach

Key messages

Portuguese population is exposed to mycotoxins, chemical food contaminants that may be harmful (carcinogenic, immunotoxic, mutagenic, teratogenic, hepatotoxic) for human health. Human biomonitoring studies provide realistic data on internal exposure at individual level, allowing a more accurate knowledge of the determinants of exposure to these contaminants.

Multidrug-resistant tuberculosis in Lisbon: unfavourable treatment and associated factors, 2000-2014

SETTING: The incidence of tuberculosis (TB) has been decreasing in Portugal. Lisbon concentrates the largest number of cases of multidrug-resistant (MDR) TB in the country. This study aims at identifying clinical and demographic factors associated with unfavourable treatment results of patients with MDR-TB in the city.METHOD: The data on 265 MDR-TB cases, notified from 2000 to 2014 in the District of Lisbon, were collected from the Tuberculosis Surveillance System. Unfavourable cases were classified as failure, loss to follow-up (LTFU) and death. Bivariate and multivariate logistic regressions were undertaken to estimate the factors associated with unfavourable outcomes, LTFU and death.RESULTS: The proportion of unfavourable outcomes was 30.5%. These were associated mostly with being male, foreign-born and resistant to kanamycin. Death was associated with being human immunodeficiency virus-positive and resistant to kanamycin. Being foreign-born had a 4.46-fold higher odds of a LTFU outcome than did being Portuguese-born. The foreign-born patients were mostly African immigrants.CONCLUSION: The main finding in this study is that foreign-born patients are associated with a higher probability of unfavourable outcomes than Portuguese-born patients. Therefore, foreign-born patients need more careful monitoring in the control of MDR-TB.
