When and why do people change their minds in favor of vaccination? Longitudinal analyses of switching COVID-19 vaccination preferences.

Background: Vaccinations are a cornerstone of public health. However, reluctance to accepting vaccines is common. Using longitudinal data, we investigated which individual and contextual factors were associated with switching preferences from initial hesitancy or unwillingness toward acceptance of a first COVID-19 vaccination.

Patterns of News Consumption during the COVID-19 Pandemic Crisis: A 2.5 Year Longitudinal Study in the Netherlands.

During major long-term crises, such as the COVID-19 pandemic, news media are crucial sources of information for the public. This study aimed to explore the frequency of COVID-19-related news consumption based on (1) phase of the pandemic, (2) socio-demographic characteristics, and (3) news information channels. The study used a dynamic cohort design with 18 rounds of data collection, including 306,692 responses from 83,180 unique respondents in the Netherlands from 17 April 2020 to 11 September 2022.

Psychosocial determinants of handwashing and physical distancing behaviour during the COVID-19 pandemic in the Netherlands: A longitudinal analysis.

Objectives: Physical distancing and handwashing can be important infection prevention measures during an infectious disease outbreak such as the COVID-19 pandemic. To stimulate these behaviours, knowledge of psychosocial determinants as well as contextual factors is vital. We present longitudinal, within-person analyses of the impact of contextual and psychosocial factors on handwashing and distancing behaviour.

Patient-reported outcomes of adverse events after COVID-19 vaccination in Nigeria: A mixed methods study.

Background: Adverse events following immunization (AEFIs), especially if serious, may impact vaccine recipients' quality of life and financial well-being and fuel vaccine hesitancy. Nigeria rolled out COVID-19 vaccination in 2021 with little known about the impact of AEFIs on an individual's quality of life. No study in Africa has explored the health and financial impact of AEFIs.

Mobile vaccination units to increase COVID-19 vaccination uptake in areas with lower coverage: a within-neighbourhood analysis using national registration data, the Netherlands, September-December 2021.

BackgroundVaccine uptake differs between social groups. Mobile vaccination units (MV-units) were deployed in the Netherlands by municipal health services in neighbourhoods with low uptake of COVID-19 vaccines.AimWe aimed to evaluate the impact of MV-units on vaccine uptake in neighbourhoods with low vaccine uptake.

A cardiac-rehab behaviour intervention to reduce sedentary time in coronary artery disease patients: the SIT LESS randomized controlled trial.

Background: High sedentary times (ST) is highly prevalent in patients with coronary artery disease (CAD), highlighting the need for behavioural change interventions that effectively reduce ST. We examined the immediate and medium-term effect of the SIT LESS intervention on changes in ST among CAD patients enrolled in cardiac rehabilitation (CR).

Methods: CAD patients participating in CR at 2 regional hospitals were included in this randomized controlled trial (1:1, stratified for gender and hospital).

Preferences for the Societal Impacts of a Pandemic when it Transitions into an Endemic: A Discrete Choice Experiment.

Background: The stage of the pandemic significantly affects people's preferences for (the societal impacts of) COVID-19 policies. No discrete choice experiments were conducted when the COVID-19 pandemic was in a transition phase.

Objectives: This is the first study to empirically investigate how citizens weigh the key societal impacts of pandemic policies when the COVID-19 pandemic transitions into an endemic.

Can blood-based markers predict RECIST progression in non-small cell lung cancer treated with immunotherapy?

Purpose: In this study, we aimed to evaluate the potential of routine blood markers, serum tumour markers and their combination in predicting RECIST-defined progression in patients with stage IV non-small cell lung cancer (NSCLC) undergoing treatment with immune checkpoint inhibitors.

Methods: We employed time-varying statistical models and machine learning classifiers in a Monte Carlo cross-validation approach to investigate the association between RECIST-defined progression and blood markers, serum tumour markers and their combination, in a retrospective cohort of 164 patients with NSCLC.

Results: The performance of the routine blood markers in the prediction of progression free survival was moderate.

Pilot randomized controlled trial of a program to enhance experience and adherence with adjuvant endocrine therapy among women with non-metastatic breast cancer: 12-month quantitative results.

Purpose: Adjuvant endocrine therapy (AET) reduces recurrence risk after hormone receptor-positive breast cancer, but non-adherence is common. We pilot-tested SOIE, a program to enhance AET experience and adherence, to assess its acceptability, feasibility, and effects on psychosocial precursors of AET adherence.

Methods: We conducted a 12-month pilot randomized controlled trial among women who had a first AET prescription.

Design of a Multiple-Behavior Change Intervention for Supporting Self-management in Patients With Chronic Heart Failure: An Intervention Mapping Approach.

Background: Nonadherence to medication and low physical activity contribute to morbidity, mortality, and decreased quality of life among patients with chronic heart failure (CHF). Effective interventions that can be delivered during routine clinical care are lacking.

Objective: We aimed to adapt the feasible and cost-effective Adherence Improving self-Management Strategy (AIMS) for patients with human immunodeficiency virus (HIV) to CHF treatment.

Estimating the impact of COVID-19 self-test availability and modifications in test-strategy on overall test uptake using an experimental vignette study.

To inform future Dutch COVID-19 testing policies we did an experimental vignette study to investigate whether inclusion of the less reliable lateral flow tests (self-tests) would change test-uptake sufficiently to improve population-level test sensitivity. A representative sample (n = 3,270) participated in a 2-by-2 online experiment to evaluate the effects of test-guidelines including self-testing advice (IV1), and the effects of self-test availability (IV2) on expected test uptake (PCR test, self-test or no test) and sensitivity of the overall test strategy (primary outcome). Across four scenarios, changing test advice did not affect expected testing behaviour.

Effectiveness of a COVID-19 contact tracing app in a simulation model with indirect and informal contact tracing.

During the COVID-19 pandemic, contact tracing was used to identify individuals who had been in contact with a confirmed case so that these contacted individuals could be tested and quarantined to prevent further spread of the SARS-CoV-2 virus. Many countries developed mobile apps to find these contacted individuals faster. We evaluate the epidemiological effectiveness of the Dutch app CoronaMelder, where we measure effectiveness as the reduction of the reproduction number R.

Mental health of healthcare workers during the first year of the COVID-19 pandemic in the Netherlands: a longitudinal study.

Purpose: In March 2020, the WHO declared COVID-19 a pandemic. Previous virus outbreaks, such as the SARS outbreak in 2003, appeared to have a great impact on the mental health of healthcare workers. The aim of this study is to examine to what extent mental health of healthcare workers differed from non-healthcare workers during the first year of the COVID-19 pandemic.

Mental health during the COVID-19 pandemic in children and adolescents with ADHD: A systematic review of controlled longitudinal cohort studies.

Prior studies reported mixed effects of the COVID-19 pandemic on the mental health of children and adolescents with ADHD, but they were mainly cross-sectional and without controls. To clarify the impact, we searched Web of Science, EMBASE, Medline, and PsychINFO until 18/11/2023 and conducted a systematic review of controlled longitudinal cohort studies (Prospero: CRD42022308166). The Newcastle-Ottawa scale was used to assess quality.

How well do surveys on adherence to pandemic policies assess actual behaviour: Measurement properties of the Dutch COVID-19 adherence to prevention advice survey (CAPAS).

Background: Survey data on adherence to COVID-19 prevention measures have often been used to inform policy makers and public health professionals. Although behavioural survey data are often considered to suffer from biases, there is a lack of studies critically examining the validity, reliability and responsiveness of population-survey data on behaviour throughout the COVID-19 pandemic.

Aim: We studied the measurement properties of the COVID-19 Adherence to Prevention Advice Survey (CAPAS), a novel questionnaire implemented in a repeated cross-sectional (i.

Signalling need for care: a neglected functional role of medical treatment.

Background And Objectives: While the primary goals of medical treatment are typically to shorten illness or relieve symptoms, we explore the idea that an important additional goal for some patients is to communicate their needs. Drawing on , we argue that undergoing treatments can help patients legitimize their illness and thereby enable access to crucial support during convalescence.

Methods And Results: Four pre-registered within-subjects experiments ( = 874) show that participants are more inclined to provide care to people who undergo treatment, especially when that treatment is painful.

Epidemiological surveillance of drug safety using cumulative sequential analysis in electronic healthcare data.

Background: Methods for safety signal detection in electronic healthcare data analysing data sequentially are being developed to meet the limitations of spontaneous reporting systems.

Objectives: This study aims to provide an overview of the literature on sequential analysis of electronic healthcare data and describe the development and testing of a novel epidemiological surveillance system.

Methods: We searched Medline, Embase, PubMed, Scopus, Web of Science, and the Cochrane Library applying similar in- and exclusion criteria as those of a previous systematic review.

Cortisol as Biomarker for CYP17-Inhibition is Associated with Therapy Outcome of Abiraterone Acetate.

Background: Abiraterone acetate is an irreversible 17α-hydroxylase/C17, 20-lyase (CYP17) inhibitor approved for the treatment of metastatic castration-resistant prostate cancer (mCRPC) patients. Inhibition of this enzyme leads to low testosterone and cortisol levels in blood. There is growing evidence that clinical efficacy of abiraterone is related to the rate of suppression of serum testosterone.

Tailoring CONSORT-SPI to improve the reporting of smoking cessation intervention trials: An expert consensus study.

Background And Aims: Inadequate reporting of smoking cessation intervention trials is common and leads to significant challenges for researchers. The aim of this study was to tailor CONSORT (Consolidated Standards of Reporting Trials)-SPI (Social and Psychological Interventions) guidelines to improve reporting of trials of behavioural interventions to promote smoking cessation.

Method: Informed by missing data from the IC-SMOKE (Intervention and Comparison group support provided in SMOKing cEssation) systematic review project, this study used a multi-stage Delphi process to examine which items could be added or modified to improve the reporting of smoking cessation trials.

Context Matters: Patterns in Physical Distancing Behavior Across Situations and Over Time During the Covid-19 Pandemic in the Netherlands.

Background: Physical distancing is an effective preventative measure during respiratory infectious disease outbreaks. Prior studies on distancing behaviors have largely ignored context characteristics (physical, social) and time.

Purpose: We investigated patterns in physical distancing over time and across situations, as well as sociodemographic variation herein.

Duration of Effectiveness Evaluation of Additional Risk Minimisation Measures for Centrally Authorised Medicinal Products in the EU Between 2012 and 2021.

Introduction: In studies evaluating the effectiveness of additional risk minimisation measures (aRMMs), the need for speed must be properly balanced with the quality of the study. We assessed the duration of aRMM effectiveness evaluations, using additional pharmacovigilance activities, for centrally authorised medicinal products in the European Union.

Methods: We established a cohort of medicinal products with aRMMs at marketing authorisation (MA) that were centrally authorised from July 2012-December 2021 using the European Public Assessment Reports.

Perspectives on how to build bridges between regulation, health technology assessment and clinical guideline development: a qualitative focus group study with European experts.

Objective: Improving synergy among regulation, health technology assessment (HTA) and clinical guideline development is relevant as these independent processes are building on shared evidence-based grounds. The two objectives were first to assess how convergence of evidentiary needs among stakeholders may be achieved, and second, to determine to what extent convergence can be achieved.

Design: Qualitative study using eight online dual-moderator focus groups.

Impact of a Treatment Guide on Intravenous Fluids in Minimising the Risk of Hospital-Acquired Hyponatraemia in Denmark.

Hypotonic intravenous (IV) fluids are associated with an increased risk of hospital-acquired hyponatraemia, eventually leading to brain injury and death. We evaluated the effectiveness of a treatment guide to improve prescribing practices of IV fluids. We conducted a before-and-after cross-sectional survey among physicians working at Danish emergency departments.

Needle-based confocal laser endomicroscopy for real-time granuloma detection.

Background And Objective: Needle-based confocal laser endomicroscopy (nCLE) allows real-time microscopic imaging at the needle tip. nCLE malignancy criteria are used for tool-in-lesion confirmation during bronchoscopic lung nodule analysis. However, to date, nCLE criteria for granulomas are lacking.
