Most actions targeting children's health behaviors have limited involvement of children in the development, potentially contributing to disappointing effectiveness. Therefore, in the 3-year "Kids in Action" study, 9- to 12-year-old children from a lower-socioeconomic neighborhood were involved as coresearchers in the development, implementation, and evaluation of actions targeting health behaviors. The current study describes the controlled trial that evaluated the effects on children's energy balance-related behaviors, physical fitness, and self-rated health, as well as experienced challenges and recommendations for future evaluations. Primary school children from the three highest grades of four intervention and four control schools were eligible for participation. Outcome measures assessed at baseline, and at 1- and 2-year follow-up were as follows: motor fitness by the MOPER test (N = 656, N = 485, N = 608, respectively), physical activity and sedentary behavior by accelerometry (N = 223, N = 149, N = 164, respectively), and consumption of sugar sweetened beverages and snacks and self-rated health by a questionnaire (N = 322, N = 281, N = 275, respectively). Mixed-model analyses were performed adjusted for clustering within schools and relevant confounders. Significant beneficial intervention effects were found on self-reported consumption of energy/sports drinks at T2 versus T0, and on total time and [greater than or equal to]5-minute bouts of moderate-to-vigorous physical activity at T1 versus T0. Significant adverse effects were found on "speed and agility" and "coordination and upper-limb speed." No other significant effects were found. The inconsistent intervention effects may be explained by the dynamic cohort and suboptimal outcome measures. We advise future studies with a similar approach to apply alternative evaluation designs, such as the delayed baseline design.

Aims The diagnostic performance of quantitative perfusion cardiac magnetic resonance (QP-CMR) imaging has scarcely been evaluated in patients with a history of coronary artery disease (CAD) and new onset chest pain. The present study compared the diagnostic performance of automated QP-CMR for the detection of fractional flow reserve (FFR) defined hemodynamically significant CAD with visual assessment of first-pass stress perfusion CMR (v-CMR) and quantitative [15O]H2O positron emission tomography (PET) imaging in a true head-to-head fashion in patients with prior CAD. Methods and results This PACIFIC-2 substudy included 145 symptomatic chronic coronary symptom patients with prior myocardial infarction and/or percutaneous coronary intervention. All patients underwent dual-sequence, single-bolus perfusion CMR, and [15O]H2O PET perfusion imaging followed by invasive coronary angiography with three-vessel FFR. Hemodynamically significant CAD was defined as an FFR ≤ 0.80. QP-CMR, v-CMR, and PET exhibited a sensitivity of 66, 67, and 80%, respectively, whereas specificity was 60, 62, and 63%. Sensitivity of QP-CMR was lower than that of PET (P = 0.015), whereas the specificity of QP-CMR and PET was comparable. Diagnostic accuracy and area under the curve of QP-CMR (64% and 0.66) was comparable to both v-CMR [66% (P = not significant [NS]) and 0.67 (P = NS)] and PET [74% (P = NS) and 0.78 (P = NS)]. Conclusion In patients with prior myocardial infarction and/or percutaneous coronary intervention, the diagnostic performance of QP-CMR was comparable to visual assessment of first-pass stress perfusion CMR and quantitative [15O]H2O PET for the detection of hemodynamically significant CAD as defined by FFR.

Background: Dutch adolescents predominantly purchase unhealthy snacks in supermarkets, which negatively influence their health. The aim of this study was to investigate the short- and longer-term effects of a nutrition peer-education intervention in supermarkets on food purchases and determinants of food purchase behaviour among adolescents of different education levels. Methods: We performed a quasi-experimental study in three supermarkets (two intervention and one comparison school) in Amsterdam, the Netherlands. The intervention schools received a 45-min peer-education workshop in the supermarket near their school, and the comparison school received no intervention. The workshops also included a 2-week 'healthy snacking challenge' and were led by two young supermarket employees. Measurements were performed 2 weeks before the intervention (T0) 2 weeks after (T1) and 3 months (T2) after the intervention. Cash receipts were used to examine food purchases (n = 458) and questionnaires to examine determinants of food purchase behaviour (n = 463). Results: The nutrition peer-education intervention did not improve food purchases but did improve several determinants of food purchase behaviour. Adolescents from the intervention schools reported improved nutritional knowledge (β = 0.38, 95% CI: 0.04–0.72) at T1, more favourable attitudes (β = 0.21, 95% CI: 0.00–0.42) and stronger social support (β = 0.27, 95% CI: 0.02–0.53) for healthy food purchases at T2 compared to those from the comparison schools. Adolescents with a low level of education reported more short- and longer-term improvements of determinants of food purchase behaviour compared to those with a higher level of education. Conclusions: While nutrition peer education in supermarkets did not improve adolescents' food purchases in the supermarket, determinants of food purchase behaviour did improve. The intervention was especially effective among adolescents with a low level of education. Nevertheless, to promote healthy food purchases of adolescents in supermarkets, more efforts are needed.

Background: Over half of preterm neonates with necrotizing enterocolitis (NEC) require surgery, making it essential to understand short-term postoperative outcomes and complication rates. Therefore, this study aimed to provide an overview of 30-day postoperative complications for NEC. Secondary, risk factors for minor and major short-term postoperative complications were identified. Methods: This retrospective study included all preterm infants (GA < 35w) surgically treated for NEC from 2008 to 2022. Postoperative complications were scored following the Clavien–Madadi classification. Risk factors were analyzed using multivariable logistic regression analysis. Results: In this cohort of 326 patients, 204 received a stoma, 80 had a primary anastomosis, and 32 had both. Postoperative mortality was 19.0%. In total, 186 patients experienced 238 complications (57.1%), including 118 (63.4%) major and 68 (36.6%) minor complications. Most common complications were sepsis (19.4%), stoma-related (13.3%), and wound dehiscence (11.3%). Cardiovascular support between NEC diagnosis and surgery was a significant risk factor for major complications (OR: 1.92, 95%-CI 1.19–3.08, p = 0.007) and stoma creation for minor complications (OR: 6.73, 95%-CI 2.05–22.05, p = 0.002). Conclusion: This study showed a postoperative complication rate of 57.1%. We found cardiovascular support between NEC diagnosis and surgery as risk factor for major complications and stoma creation as risk factor for minor complications. These findings provide valuable insights for improving parental counseling on NEC outcomes. Level of evidence: II [ABSTRACT FROM AUTHOR]

OBJECTIVES The VRECOVERY investigated the impact of virtual reality (VR) distraction therapy on postoperative pain, anxiety and quality of recovery in patients undergoing coronary artery bypass grafting surgery. METHODS A single-centre randomized controlled trial was conducted involving 192 participants, allocated to either the intervention or control group. Participants in the intervention group received VR distraction therapy on postoperative days 1, 2 and 3, while the control group received standard postoperative care. Primary outcomes were measured in both groups directly following the VR sessions of the intervention group. Outcomes included (i) postoperative pain [Numeric Rating Scale (NRS)], (ii) postoperative anxiety [State Trait Anxiety Inventory 6 questionnaire (STAI-6)] and (iii) quality of postoperative recovery [Quality of Recovery 15 questionnaire (QoR-15)]. RESULTS A total of 100 participants completed the study, including 39 patients (mean age 69.1 ± 7.7 years) in the intervention group and 61 patients (mean age 66.8 ± 8.2 years) in the control group. Eighty-nine percent of participants was male. VR-distraction therapy demonstrated a significant difference in postoperative pain decrease between groups (NRS score; intervention group −1.45/day vs control group −0.73/day, P  =   0.007), and an important overall difference in postoperative anxiety slopes (STAI-6 score; intervention group −0.60/day vs control group +0.09/day, P  =   0.06). There was no effect observed on postoperative quality of recovery (P  =   0.11). CONCLUSIONS The VRECOVERY trial suggests a beneficial impact of VR distraction therapy in reducing postoperative pain. There was no significant effect on postoperative anxiety and quality of recovery. [ABSTRACT FROM AUTHOR]

Background/objectives: A significant number of COVID-19 cases experience persistent symptoms after the acute infection phase, a condition known as long COVID or post-acute sequelae of COVID-19. Approved prevention and treatment options for long COVID are currently lacking. Given the heterogeneous nature of long COVID, a personalized medicine approach is essential for effective disease management. This study aimed to describe trends in pharmacotherapy from pre-COVID to post-COVID phases to gain insights into COVID-19 treatment strategies and assess whether pre-COVID pharmacotherapy can predict long COVID symptoms as a health status indicator. Methods: In the Precision Medicine for more Oxygen (P4O2) COVID-19 study, 95 long COVID patients were comprehensively evaluated through post-COVID outpatient clinics and study visits. This study focused on descriptive analysis of the pharmacotherapy patterns across different phases: pre-COVID-19, acute COVID, and post-COVID. Furthermore, associations between pre-COVID medication and long COVID outcomes were analyzed with regression analyses. Results: We observed peaks in the use of certain medications during the acute infection phase, including corticosteroids and antithrombotic agents, with a decrease in the use of renin–angiotensin system inhibitors. Consistently high use of alimentary tract medications was found across all phases. Pre-COVID respiratory medications were associated with fatigue symptoms, while antiinfectives and cardiovascular drugs were linked to fewer persisting long COVID symptom categories. Conclusion: Our findings provide longitudinal, descriptive pharmacotherapy insights and suggest that medication history can be a valuable health status indicator in characterizing patients for personalized disease management strategies, considering the heterogeneous nature of long COVID.

Background: Although the coronavirus disease 2019 (COVID-19) pandemic is no longer a public health emergency of international concern, 30% of COVID-19 patients still have long-term complaints. A better understanding of the progression of symptoms after COVID-19 is needed to reduce the burden of the post COVID-19 condition. Objective: This study aims to investigate the progression of symptoms, identify patterns of symptom progression, and assess their associations with patient characteristics. Methods: Within the P4O2 COVID-19 study, patients aged 40–65 years were recruited from five Dutch hospitals. At 3–6 and 12–18 months post COVID-19, medical data were collected, and pulmonary function tests were performed. In between, symptoms were assessed monthly with a questionnaire. Latent class mixed modelling was used to identify symptom progression patterns over time, with multinomial logistic regression to examine associations with patient characteristics. Results: Eighty-eight patients (aged 54.4 years, 48.9% males) were included. Three trajectories were identified for fatigue and dyspnoea: decreasing, high persistent, and low persistent. The odds of "decreasing fatigue" was higher for never smokers and participants in the lifestyle intervention and lower for those having a comorbidity. The odds of "decreasing dyspnoea" was higher for moderate COVID-19 patients and lifestyle intervention participants and lower for males, mild COVID-19 patients, and those with a higher age. Conclusions: Three distinct trajectories were identified for fatigue and dyspnoea, delineating patterns of symptom persistence following COVID-19. Sex, age, smoking status, participation in lifestyle interventions and COVID-19 severity were associated with the likelihood of belonging to different trajectories. These findings highlight the heterogeneity of the long-term symptoms experienced by post COVID-19 patients and emphasise the importance of personalised treatment strategies. [ABSTRACT FROM AUTHOR]

Introduction: Imaging fibroid vascularity may predict fibroid growth and aid to determine most appropriate therapy. Microvascular (MV) flow imaging is relatively new and is able to detect slow flow in small vessels. Data on feasibility, reproducibility, and reliability of MV‐flow imaging in fibroids is lacking. The purpose of our study was to determine the reproducibility of MV‐flow imaging and to explore this technique for clinical practice for assessing blood flow in fibroids. Material and Methods: Thirty patients with one or multiple fibroids (diameter 1.5–12.0 cm) were prospectively included. Transvaginal ultrasound scanning was performed in B‐mode, 2D MV‐Flow™, 2D and 3D power Doppler mode (HERA W10, Samsung) by two experienced gynecologists at a tertiary care clinic from February to December 2021. The primary outcome was intra‐ and interobserver agreement of the vascular index (VI) and color score (CS). The following parameters: '2D MV‐flow VI', '3DPD VI', '2D MV‐flow CS' and '2DPD CS' were measured offline in the center, pseudocapsule, and entire fibroid. Secondary offline outcomes for exploring 2D MV‐flow for clinical practice, included (1) ability to discern vascular structures, (2) assessing the degree of vascularity via CS and calculating a VI, and (3) determining penetration depth of the ultrasound signal in both power Doppler and MV‐flow imaging. Results: All scans of the 30 included patients were of sufficient quality to analyze. Inter‐ and intra‐observer correlations of all studied parameters were good to excellent, both for 2D MV‐flow and 2D power Doppler (intercorrelation coefficient 0.992–0.996). Using 2D MV‐flow different vascular structures were visible in detail, in contrary to using 2D and 3D power Doppler. In significantly more fibroids central flow could be visualized using 2D MV‐flow (63%) than with 2D power Doppler (13%, p = 0.001). Finally, penetration of the ultrasound signal was deeper using 2D MV‐flow (3.92 cm) than with 2D power Doppler (2.95 cm, p = 0.001). Conclusions: Using 2D MV‐flow imaging for determining vascularity is highly reproducible. It has potential added value for clinical practice as it depicts detailed vascular structures and the degree of vascularity, especially in the center of the fibroid. [ABSTRACT FROM AUTHOR]

Interpersonal psychotherapy (IPT) and antidepressant medications are both first-line interventions for adult depression, but their relative efficacy in the long term and on outcome measures other than depressive symptomatology is unknown. Individual participant data (IPD) meta-analyses can provide more precise effect estimates than conventional meta-analyses. This IPD meta-analysis compared the efficacy of IPT and antidepressants on various outcomes at post-treatment and follow-up (PROSPERO: CRD42020219891). A systematic literature search conducted May 1st, 2023 identified randomized trials comparing IPT and antidepressants in acute-phase treatment of adults with depression. Anonymized IPD were requested and analyzed using mixed-effects models. The prespecified primary outcome was post-treatment depression symptom severity. Secondary outcomes were all post-treatment and follow-up measures assessed in at least two studies. IPD were obtained from 9 of 15 studies identified (N = 1536/1948, 78.9%). No significant comparative treatment effects were found on post-treatment measures of depression (d = 0.088, p = 0.103, N = 1530) and social functioning (d = 0.026, p = 0.624, N = 1213). In smaller samples, antidepressants performed slightly better than IPT on post-treatment measures of general psychopathology (d = 0.276, p = 0.023, N = 307) and dysfunctional attitudes (d = 0.249, p = 0.029, N = 231), but not on any other secondary outcomes, nor at follow-up. This IPD meta-analysis is the first to examine the acute and longer-term efficacy of IPT v. antidepressants on a broad range of outcomes. Depression treatment trials should routinely include multiple outcome measures and follow-up assessments. [ABSTRACT FROM AUTHOR]

Background and Objectives: Regular whole blood donations are associated with an increased risk of iron deficiency. Iron supplementation is an effective strategy to prevent donation‐induced iron deficiency. However, research on donor perceptions towards such a policy is limited. Therefore, we aim to evaluate donors' knowledge on donation‐induced iron depletion and their perceptions regarding iron supplementation as a blood service policy. Materials and Methods: Three thousand Dutch whole blood donors were invited to complete a survey assessing their knowledge of donation‐induced iron depletion and attitudes and perceptions towards iron supplementation as a policy. Linear regression modelling was used to evaluate associations between explanatory variables and perceptions. Results: In total, 1093 (77.1%) donors were included in the analysis. Donors had poor knowledge of current iron management policies, but a better understanding of iron metabolism and supplementation. Iron supplementation as a policy was perceived mainly positive by donors, and the majority were willing to use iron supplements if provided. Iron supplementation was not perceived as invasive or negatively affecting donors' motivation to continue donating. Additional iron monitoring, information and donor physician involvement were regarded as important conditions for implementation. Male sex, trust in the blood service, prior experience with iron supplements and openness towards dietary supplements were strongly positively associated with willingness to use iron supplementation. Conclusion: Donors' knowledge regarding donation‐induced iron depletion is limited, but not associated with their perceptions regarding iron supplementation. Donors do not consider iron supplementation as invasive, deterring or demotivating, and a majority are willing to take supplements if offered. [ABSTRACT FROM AUTHOR]
