    Exposure to CO2 at high concentration is a much debated stunning method in pigs. Pigs respond aversively to high concentrations of CO2, and there is uncertainty about what behaviors occur before and after loss of consciousness. The aim was to assess timing of unconsciousness in pigs during exposure to high concentrations of CO2 based on changes in electroencephalogram (EEG) activity and the relation with the behaviors sniffing, retreat and escape attempts, lateral head movements, jumping, muscular contractions, loss of posture, and gasping. Pigs (108 ± 9 kg) were randomly assigned to 80% CO2 (80C, n = 24) or 95% CO2 (95C, n = 24). The time at which the gondola started descending into the well pre-filled with 80C or 95C was marked as T = 0. The CO2 exposure lasted 346 s after which the corneal reflex and breathing were assessed for 1 min. Visual assessment of changes in the amplitude and frequency of EEG traces after T = 0 was used to determine loss of consciousness. Time to loss of consciousness was longer in 80C pigs (47 ± 6 s) than in 95C pigs (33 ± 7 s). Time to an iso-electric EEG was similar in 80C pigs (75 ± 23 s) and 95C pigs (64 ± 32 s). When pigs descended into the well, the earlier entry of 95C pigs into high CO2 atmosphere rather than the concentration of CO2 by itself affected the latency of behavioral responses and decreasing brain activity. During exposure to the gas, 80C and 95C pigs exhibited sniffing, retreat attempts, lateral head movements, jumping, and gasping before loss of consciousness. 95C pigs exhibited all these behaviors on average earlier than 80C pigs after T = 0. But the interval between onset of these behaviors and loss of consciousness and the duration of these behaviors, except gasping, was similar for both treatments. Loss of posture was on average observed in both groups 10 s before EEG-based loss of consciousness. Furthermore, 88% of 80C pigs and 94% of 95C pigs demonstrated muscular contractions before loss of consciousness. The findings provide little reason to conclude on a behavioral basis that these atmospheres are greatly different in their impact on pig welfare.info:eu-repo/semantics/publishedVersio

    BACKGROUND: Active transport is a convenient way to incorporate physical activity in adolescents' daily life. The present study aimed to investigate which psychosocial and environmental factors are associated with walking, cycling, public transport (train, tram, bus, metro) and passive transport (car, motorcycle, moped) over short distances (maximum eight kilometres) among older adolescents (17-18 years), to school and to other destinations. METHODS: 562 older adolescents completed an online questionnaire assessing socio-demographic variables, psychosocial variables, environmental variables and transport to school/other destinations. Zero-inflated negative binomial regression models were performed. RESULTS: More social modelling and a higher residential density were positively associated with walking to school and walking to other destinations, respectively. Regarding cycling, higher self-efficacy and a higher social norm were positively associated with cycling to school and to other destinations. Regarding public transport, a higher social norm, more social modelling of siblings and/or friends, more social support and a higher land use mix access were positively related to public transport to school and to other destinations, whereas a greater distance to school only related positively to public transport to school. Regarding passive transport, more social support and more perceived benefits were positively associated with passive transport to school and to other destinations. Perceiving less walking and cycling facilities at school was positively related to passive transport to school only, and more social modelling was positively related to passive transport to other destinations. CONCLUSIONS: Overall, psychosocial variables seemed to be more important than environmental variables across the four transport modes. Social norm, social modelling and social support were the most consistent psychosocial factors which indicates that it is important to target both older adolescents and their social environment in interventions promoting active transport. Walking or cycling together with siblings or friends has the potential to increase social norm, social modelling and social support towards active transport

    The immediate impact of the coronavirus disease 2019 (COVID-19) pandemic on burn-out, work-engagement, and surgical training in the Netherlands

    BACKGROUND: The coronavirus disease 2019 pandemic led to major changes in health care and education options for all health care employees. The aim of this study is to achieve insight into coronavirus disease-care participation of surgical residents in the Netherlands, the impact of coronavirus disease 2019 on the experienced quality of surgical training, and the influence on Burn-out and Work Engagement compared with the non-coronavirus disease 2019 period in January 2020.METHODS: In this study, we have conducted 2 digital surveys immediately before and 2 months after the start of the coronavirus disease 2019 pandemic. We surveyed a validated Dutch questionnaire 'Utrecht Burn-out Scale,' derived from the Maslach Burn-out Inventory, and also collected the 'Utrecht Work Engagement Scale' measuring work engagement. Additionally, we describe the coronavirus disease-care participation of surgical residents, the impact on how they experienced the quality of their surgical training, and the influence on 'Burn-out and Work Engagement' compared with the pre-coronavirus disease 2019 period for surgical residents in the Netherlands.RESULTS: In January 2020, a total of 317 residents completed the online survey, and in April 2020, a total of 313 residents completed the online survey. Of the responders, 48.6%, in April, participated in coronavirus disease-care in both the coronavirus disease ward as well as the coronavirus disease intensive care unit. Residents experienced that the coronavirus disease 2019 influenced their surgical training in 85.2% of responders. In only 5% of the residents did the pandemic not affect the exposure to surgical training in the operating theater. More burn-out symptoms were noted amongst coronavirus disease ward deployed residents versus no coronavirus disease ward deployment, (16.0% vs 7.6%, P = .06). The Work-Engagement questionnaire showed a significantly lower work engagement score of 4.2 for residents who were deployed in a coronavirus disease-care intensive care unit versus a score of 4.6 for residents scheduled in a coronavirus disease ward (P = .02).CONCLUSION: This study shows a significant impact of the first months of the coronavirus disease 2019 pandemic on the Dutch surgical trainee program, with a major redistribution of residents with a decrease of surgical exposure and education. We emphasize the need for adequate guidance of all surgical residents and potentially lengthening the surgical training program.</p

    Promoting active transport in older adolescents before they obtain their driving licence : a matched control intervention study

    BACKGROUND: Active transport has great potential to increase physical activity in older adolescents (17-18 years). Therefore, a theory- and evidence-based intervention was developed aiming to promote active transport among older adolescents. The intervention aimed to influence psychosocial factors of active transport since this is the first step in order to achieve a change in behaviour. The present study aimed to examine the effect of the intervention on the following psychosocial factors: intention to use active transport after obtaining a driving licence, perceived benefits, perceived barriers, subjective norm, self-efficacy, habit and awareness towards active transport. METHODS: A matched control three-arm study was conducted and consisted of a pre-test post-test design with intervention and control schools in Flanders (northern part of Belgium). A lesson promoting active transport was implemented as the last lesson in the course 'Driving Licence at School' in intervention schools (intervention group 1). Individuals in intervention group 2 received this active transport lesson and, in addition, they were asked to become a member of a Facebook group on active transport. Individuals in the control group only attended the regular course 'Driving Licence at School'. Participants completed a questionnaire assessing socio-demographics and psychosocial variables at baseline, post (after one week) and follow-up (after eight weeks). To assess intervention effects, multilevel linear mixed models analyses were performed. RESULTS: A sample of 441 older adolescents (56.8% female; 17.4 (0.7) years) was analysed. For awareness regarding the existence of car sharing schemes, a significant increase in awareness from baseline to post measurement was found within intervention group 1 (p = 0.001) and intervention group 2 (p = 0.030) compared to the control group in which no change was found. In addition, a significant increase in awareness from baseline to follow-up measurement was found within intervention group 1 (p = 0.043) compared to a decrease in awareness from baseline to follow-up measurement within the control group. CONCLUSIONS: Overall, the intervention was not effective to increase psychosocial correlates of active transport. Future intervention studies should search for alternative strategies to motivate and involve this hard to reach target group

    Antenatal cardiotocography in dutch primary midwife-led care:Maternal and perinatal outcomes and serious adverse events. A prospective observational cohort study

    Problem: It is yet unknown whether shifting antenatal cardiotocography (aCTG) from obstetrician-led to midwife-led care leads to a safe reduction in referrals.Background: ACTG is used to assess fetal well-being. In the Netherlands, the procedure has until now been performed as part of obstetrician-led care. Developments in E-health facilitates the performance of aCTG outside the hospital in midwife-led care, hereby increasing continuity of care.Aim: To evaluate 1) process outcomes of implementing aCTG for specific indications in primary midwife-led care; 2) maternal and perinatal outcomes of pregnant women receiving aCTG in midwife-led care; 3) serious adverse events (with outcomes, causes, avoidability, and potential prevention strategies) that have occurred during the innovation project ‘aCTG in midwife-led care’.Methods: Prospective observational cohort study and a case series study of serious adverse events.Findings: A total of 1584 pregnant women with a specific aCTG indication were included in this cohort study for whom 1795 aCTGs were performed in midwife-led care. 1591 aCTGs(89.7%) were classified as reassuring. Referral to obstetrician-led care occurred for 234 women(13.0%) after an aCTG in midwife-led care of whom 202(86%) were referred back. Severe neonatal morbidity occurred in 27 neonates (1.7%). In the 5736 aCTGs included in the case series study, one case with a serious neonatal outcome was assessed as a serious adverse event attributable to human factors.Discussion: ACTGs performed in midwife-led care increased continuity of care. In this innovation project, maternal and perinatal outcomes were in the expected range for women in midwife-led care.</p

    Background: As previous studies showed significant hospital variation in curative treatment of esophagogastric cancer, this study assesses the association between this variation and overall, cancer-specific and recurrence-free survival, and Health-Related Quality of Life (HRQoL). Methods: Patients diagnosed with potentially curable esophageal or gastric cancer between 2015 and 2018 as registered in the Netherlands Cancer Registry were included. Data on overall survival was available for all patients, data on cancer-specific and recurrence-free survival and HRQoL was available for subgroups. Patients were classified according to diagnosis in hospitals with low, medium or high probability of treatment with curative intent (LP, MP or HP). Multivariable models were used to assess the association between LP, MP and HP hospitals and HRQoL and survival. Results: This study includes 7,199 patients with esophageal, and 2,407 with gastric cancer. Overall and cancer-specific survival was better for patients diagnosed in HP versus LP hospitals for both esophageal (HR = 0.82, 95%CI:0.77–0.88 and HR = 0.82, 95%CI:0.75–0.91, respectively), and gastric cancer (HR = 0.82, 95%CI:0.73–0.92 and HR = 0.74, 95%CI:0.64–0.87, respectively). These differences disappeared after adjustments for treatment. Recurrence-free survival was worse for gastric cancer patients diagnosed in HP hospitals (HR = 1.50, 95%CI:1.14–1.96), which disappeared after adjustment for radicality of surgery. Minor, but no clinically relevant, differences in HRQoL were observed.Conclusions: Patients diagnosed in hospitals with a high probability of treatment with curative intent have a better overall and cancer-specific but not recurrence-free survival, while minor differences in HRQoL were observed.</p

    Effective low-dose sirolimus regimen for kaposiform haemangioendothelioma with Kasabach-Merritt phenomenon in young infants

    Get PDF
    Aims Management of kaposiform haemangioendotheliomas (KHE) with Kasabach-Merritt phenomenon is challenging in young infants who are subjected to developmental pharmacokinetic changes. Sirolimus, sometimes combined with corticosteroids, can be used as an effective treatment of KHE. Simultaneously, toxicities such as interstitial pneumonitis related to the use of sirolimus may be fatal. As infants have a very low CYP3-enzyme expression at birth, which rises during ageing, we hypothesize that a reduced metabolization of sirolimus might lead to high sirolimus serum levels and low dose may be sufficient without the side effects. Methods A case series of 5 infants with kaposiform haemangioendothelioma with Kasabach-Merritt phenomenon was analysed retrospectively. All infants were treated with sirolimus 0.2 mg/m(2) every 24 or 48 hours according to their age. Prednisone was added to the therapy for additional effect in 4 patients. Results In all patients, low dose of sirolimus led to therapeutic sirolimus levels (4-6 ng/mL). All infants (aged 4 days-7 months) had a complete haematological response, without serious adverse events. In all patients, the Kasabach-Merritt phenomenon resolved, the coagulation profile normalized and tumour size reduction was seen. Conclusion Low-dose sirolimus treatment is safe for infants with kaposiform haemangioendothelioma and Kasabach-Merritt phenomenon. It is essential to realize that during the first months of life, metabolism is still developing and enzymes necessary to metabolise drugs like sirolimus still have to mature. To avoid toxic levels, the sirolimus dosage should be based on age and the associated pharmacological developments
