In colonial breeding species, the number of adverse social interactions during early-life typically varies with breeding density. Phenotypic plasticity can help dealing with this social context, by allowing offspring to adjust their behaviour. Furthermore, offspring may not be unprepared since mothers can allocate resources to their embryos that may pre-adjust them to the post-hatching conditions. Thus, we hypothesize that lesser black-backed gull chicks raised in dense breeding areas, with greater exposure to intra-specific aggression, show...

Abstract Background A longstanding debate exists about including a ‘reason for use’ on prescriptions for medication. Little is known, however, about patients’ opinions on this subject. Methods An internet-based questionnaire, consisting mainly of Likert scale questions, was distributed online to the general public in Belgium. Results from 1034 responses were analyzed using descriptive statistics. Results Opinions from patients toward including a ‘reason for use’ on medication prescriptions were generally positive. A clear majority of 62%...

Abstract Background Land-use is a major driver of changes in biodiversity worldwide, but studies have overwhelmingly focused on above-ground taxa: the effects on soil biodiversity are less well known, despite the importance of soil organisms in ecosystem functioning. We modelled data from a global biodiversity database to compare how the abundance of soil-dwelling and above-ground organisms responded to land use and soil properties. Results We found that land use affects overall abundance differently in soil...

Abstract Background Bedaquiline (BDQ) is a core drug for rifampicin-resistant tuberculosis (RR-TB) treatment. Accurate prediction of a BDQ-resistant phenotype from genomic data is not yet possible. A Bayesian method to predict BDQ resistance probability from next-generation sequencing data has been proposed as an alternative. Methods We performed a qualitative study to investigate the decision-making of physicians when facing different levels of BDQ resistance probability. Fourteen semi-structured interviews were conducted with physicians experienced in treating RR-TB,...

Abstract Background European countries are increasingly harmonising their organ donation and transplantation policies. Although a growing number of nations are moving to presumed consent to deceased organ donation, no attempts have been made to harmonise policies on individual consent and the role of the family in the decision-making process. Little is known about public awareness of and attitudes towards the role of the family in their own country and European harmonisation on these health policy...

Abstract Background PFAS are persistent, bioaccumulative compounds repelling water, oil and stains which are widely used. There is mounting evidence linking exposure to a range of adverse health outcomes including renal, hepatic, immunotoxic, reproductive, endocrine disrupting and carcinogenic effects. PFAS possibly also induce neurobehavioral and developmental effects. Within Flanders Environment and Health Studies (FLEHS) internal exposure to PFAS and relevant health effects are assessed since 2008. Results Adolescents 14–15 y (2010–2011) living in an industrially...

Abstract Background Evidence and advice for pregnant women evolved during the COVID-19 pandemic. We studied social contact behaviour and vaccine uptake in pregnant women between March 2020 and September 2021 in 19 European countries. Methods In each country, repeated online survey data were collected from a panel of nationally-representative participants. We calculated the adjusted mean number of contacts reported with an individual-level generalized additive mixed model, modelled using the negative binomial distribution and a log...

Abstract Background High-risk medications use at home entails an increased risk of significant harm to the patient. While interventions and strategies to improve medications care have been implemented in hospitals, it remains unclear how this type of medications care is provided in the home care setting. The objective was to describe home care nurses’ management of high-risk medications. Methods A cross-sectional, descriptive design was set up in home care nurses in Flanders, Belgium. Participants were...

Abstract Background Matched field-substitution has been applied in the Belgian Health Interview Survey (BHIS) since the first round. During data-collection, non-participating households are replaced by substitute households, if needed up to seven times. In this manuscript, the use of field-substitution in the six rounds of BHIS (1997–2018) is assessed. We investigated to what extent field-substitution contributes to obtaining the requested net-sample size and whether this has evolved throughout the successive BHIS’s. Methods Harmonized para-data gathered...

Abstract Background Over the last decades, adolescents’ sleep has deteriorated, suggesting the need for effective healthy sleep interventions. To develop such interventions, it is important to first gather insight into the possible factors related to sleep. Moreover, previous research has indicated that chances of intervention effectivity could be increased by actively involving adolescents when developing such interventions. This study examined psychosocial factors related to sleep in adolescents and investigated adolescents’ willingness to participate in the...

We investigated the effect of isoflurane and ketamine-xylazine anesthesia on the positron emission tomography (PET) tracer [18F]SynVesT-1 in the mouse brain. [18F]SynVesT-1 PET scans were performed in C57BL/6J mice in five conditions: isoflurane anesthesia (ANISO), ketamine-xylazine (ANKX), awake freely moving (AW), awake followed by isoflurane administration (AW/ANISO) or followed by ketamine-xylazine (AW/ANKX) 20 min post tracer injection. ANISO, ANKX and AW scans were also performed in mice administered with levetiracetam (LEV, 200 mg/kg) to assess...

Visual symbols, such as logos, landmark pictures, and mascots, play a significant role in attracting tourists and improving destination images. However, only a few studies have examined how the basic visual elements of these symbols influence potential tourists’ responses to a destination. This study aims to investigate the role of color lightness in destination visual symbols. Through three experiments, we repeatedly found that lightened visual symbols nudged consumers to evaluate their destination better. Furthermore, positive...

Abstract Background The COVID-19 outbreak had an important impact on general practice, for example the lack of personal protective equipment (PPE) and the switch to telephone consultations. We installed a monitoring instrument and reported the burden the COVID-19 pandemic placed on Belgian general practitioners (GPs) during the first wave of the pandemic. Methods We conducted an observational longitudinal prospective study from the 19th of March until the 17th of August 2020. Daily data were collected...

Abstract Introduction The management of postoperative pain in anaesthesia is evolving with a deeper understanding of associating multiple modalities and analgesic medications. However, the motivations and barriers regarding the adoption of opioid-sparing analgesia are not well known. Methods We designed a modified Delphi survey to explore the perspectives and opinions of expert panellists with regard to opioid-sparing multimodal analgesia. 29 anaesthetists underwent an evolving three-round questionnaire to determine the level of agreement on certain aspects...

Abstract Background Since 2013, the National Malaria Control Programme in mainland Tanzania and the Zanzibar Malaria Elimination Programme have implemented mass insecticide-treated net (ITN) distribution campaigns, routine ITN distribution to pregnant women and infants, and continuous distribution through primary schools (mainland) and community leaders (Zanzibar) to further malaria control efforts. Mass campaigns are triggered when ITN access falls below 40%. In this context, there is a need to monitor ITN access annually to assess whether...

Abstract Background Type 2 diabetes (T2D) is an increasingly dominant disease. Interventions are more effective when carried out by a prepared and proactive team within an organised system — the integrated care (IC) model. The Chronic Care Model (CCM) provides guidance for its implementation, but scale-up of IC is challenging, and this hampers outcomes for T2D care. In this paper, we used the CCM to investigate the current implementation of IC in primary care in...

Abstract Background Respiratory syncytial virus (RSV) causes a substantial burden of acute lower respiratory infection in children under 5 years, particularly in low- and middle-income countries (LMICs). Maternal vaccine (MV) and next-generation monoclonal antibody (mAb) candidates have been shown to reduce RSV disease in infants in phase 3 clinical trials. The cost-effectiveness of these biologics has been estimated using disease burden data from global meta-analyses, but these are sensitive to the detailed age breakdown of...

Abstract Background Threats to maintaining high population access with effective bed nets persist due to errors in quantification, bed net wear and tear, and inefficiencies in distribution activities. Monitoring bed net coverage is therefore critical, but usually occurs every 2–3 years through expensive, large-scale household surveys. Mobile phone-based survey methodologies are emerging as an alternative to household surveys and can provide rapid estimates of coverage, however, little research on varied sampling approaches has been conducted...

Abstract Background In spite of the global reduction of 21% in malaria incidence between 2010 and 2015, the disease still threatens many lives of children and pregnant mothers in African countries. A correct assessment and evaluation of the impact of malaria control strategies still remains quintessential in order to eliminate the disease and its burden. Malaria follow-up studies typically involve routine visits at pre-scheduled time points and/or clinical visits whenever individuals experience malaria-like symptoms. In...

Abstract Background To address the many challenges health systems and communities face, primary care is constantly searching for new strategies to improve quality of care. One of the strategies is to focus on patients’ personal goals to direct the care process. To adopt an explicit focus on patients’ personal goals, actions at different levels are required. As a first step in this process, this study aims to explore the experiences of primary care stakeholders (i.e.,...

Abstract Background Alzheimer’s disease (AD) is an incurable neurodegenerative disorder characterised by the progressive buildup of toxic amyloid-beta (Aβ) and tau protein aggregates eventually leading to cognitive decline. Recent lines of evidence suggest that an impairment of the glymphatic system (GS), a brain waste clearance pathway, plays a key role in the pathology of AD. Moreover, a relationship between GS function and neuronal network integrity has been strongly implicated. Here, we sought to assess the...

Abstract Background and aims We aimed to identify mucin-microbiome signatures shaping the tumor microenvironment in gastric adenocarcinomas and clinical outcomes. Methods We performed high-throughput profiling of the mucin phenotypes present in 108 gastric adenocarcinomas and 20 functional dyspepsia cases using validated mucin-based RT-qPCRs with subsequent immunohistochemistry validation and correlated the data with clinical outcome parameters. The gastric microbiota was assessed by 16S rRNA gene sequencing, taxonomy, and community composition determined, microbial networks analyzed, and the...

Abstract Background Colorectal cancer liver metastases (CRCLM) are associated with a poor prognosis, reflected by a five-year survival rate of 14%. Anti-angiogenic therapy through anti-VEGF antibody administration is one of the limited therapies available. However, only a subgroup of metastases uses sprouting angiogenesis to secure their nutrients and oxygen supply, while others rely on vessel co-option (VCO). The distinct mode of vascularization is reflected by specific histopathological growth patterns (HGPs), which have proven prognostic and...
