Importance of methodological pluralism in deriving counterfactuals for evidence-based conservation.

Most protected area impact research that uses counterfactuals draws heavily on quantitative methods, data, and knowledge types, making it valuable in producing generalizations but limited in temporal scope, historical detail, and habitat diversity and coverage of ecosystem services. We devised a methodological pluralistic approach, which supports social science qualitative methods, narratives, mixed methods, and interdisciplinarity, to fully unlock the potential of counterfactuals in ensuring a place-based and detailed understanding of the socioecological context and impacts of protected areas. We applied this approach to derive possible counterfactual conditions for the impact of a montane protected area on 40 years of vegetation change in the Cape Floristic Region-a global biodiversity hotspot and UNESCO World Heritage Site in South Africa. We incorporated diverse methods, knowledge, and information sources, drawing on before-after protected area comparisons for inside and outside the protected area. A significant increase in shrubland vegetation (17-30%) was observed and attributed primarily to a decline in frequent burning for grazing. This also occurred outside the protected area and was driven by socioeconomic drivers and not by concerns over biodiversity conservation or land degradation. Had the protected area not been established the area would have seen intensification of cultivation and increased road networks, buildings, and water storage in dams. Our approach increased historical temporal coverage of socioecological change and contextualized assumptions around causality. Protected area impact evaluation should reengage in place-based research that fully incorporates pluralism in methodologies for constructing counterfactuals in a way that builds regional and global understanding from the local level upward. We devised 10 key principles for deriving counterfactuals grounded in methodological pluralism, covering aspects of collaboration, cocreation, inter- and transdisciplinarity, diverse values and lived experiences, multiple knowledge types, multiple possible causal mechanisms, social science qualitative methods, perceptions, perspectives, and narratives.

Importancia del pluralismo metodológico en la derivación de situaciones contrafactuales para la conservación basada en evidencias Resumen La mayoría de las investigaciones sobre el impacto de las áreas protegidas que usan situaciones contrafactuales se basan en gran medida en métodos cuantitativos, datos y tipos de conocimiento, por lo que son muy valiosas para producir generalizaciones, pero limitadas en el enfoque temporal, el detalle histórico y la diversidad de hábitats y cobertura de los servicios ambientales. Diseñamos una estrategia metodológica pluralista, la cual apoya los métodos cualitativos de las ciencias sociales, narrativas, métodos mixtos e interdisciplinarios para utilizar por completo el potencial de las situaciones contrafactuales para asegurar un conocimiento detallado y basado en el lugar del contexto socio ecológico y el impacto de las áreas protegidas. Aplicamos esta estrategia para derivar las posibles condiciones contrafactuales del impacto de un área protegida montañosa sobre 40 años de cambio de vegetación en el reino florístico del Cabo ­ un punto caliente de biodiversidad y Sitio de Patrimonio Mundial de la UNESCO en Sudáfrica. Incorporamos varios métodos, conocimientos y fuentes de información a partir de las comparaciones antes­después dentro y fuera del área protegida. Observamos un incremento significativo en la vegetación del matorral (17­30%), el cual atribuimos principalmente en la disminución de la quema frecuente para el pastoreo. Esto también ocurrió fuera del área protegida y fue causado por factores socioeconómicos y no por preocupación por la conservación de la biodiversidad o por la degradación del suelo. De no haberse establecido el área protegida, la zona habría sufrido una intensificación de cultivos y un incremento de carreteras, edificios y almacenamiento de agua en presas. Nuestra estrategia incrementó la cobertura histórica temporal del cambio socio­ecológico y contextualizó las suposiciones sobre la causalidad. La evaluación del impacto del área protegida debe volver a la investigación basada en el lugar que incorpora de lleno el pluralismo en la metodología para construir situaciones contrafactuales de una forma que genere conocimiento regional y global a partir del nivel local y hacia arriba. Diseñamos diez principios clave para derivar las situaciones contrafactuales basados en el pluralismo metodológico, la cobertura de los aspectos de colaboración, creación conjunta, inter­ y transdisciplinariedad, valores diversos y experiencias vividas, varios tipos de conocimiento, diferentes mecanismos causales posibles, métodos cualitativos de las ciencias sociales, percepciones, perspectivas, historias y narrativas.

Parents' information needs during the first year at home with their very premature born child; a qualitative study.

Objective: To obtain insights into parents' information needs during the first year at home with their very preterm (VP) born infant. Methods: We conducted semi-structured interviews with parents of VP infants participating in a post-discharge responsive parenting intervention (TOP program). Online interviews were audiotaped and transcribed verbatim. Inductive thematic analysis was performed by two independent coders. Results: Ten participants were interviewed and had various and changing information needs during the developmental trajectory of their infant. Three main themes emerged; (1) Help me understand and cope, (2) Be fully responsible for my baby, and (3) Teach me to do it myself. Available and used sources, such as the Internet, did not meet their information needs. Participants preferred their available and knowledgeable healthcare professionals for reassurance, tailored information, and practical guidance. Conclusion: This study identified parents' information needs during the first year at home with their VP infant and uncovered underlying re-appearing needs to gain confidence in child-caring abilities and autonomy in decision-making about their infants' care. Innovation: This study provides valuable information for healthcare professionals and eHealth developers to support parental self-efficacy during the first year after preterm birth.

Survey data on the socio-economic characteristics and electric vehicle perceptions of paratransit owners and drivers in and around the Cape Town Metropole of South Africa.

The survey data contain information on the socio-economic characteristics and intention of electric vehicle (EV) adoption amongst paratransit owners and drivers, to address knowledge gaps and inform policy-making in paratransit electrification. The data were collected by distributing a Microsoft Forms survey questionnaire among paratransit owners and drivers in and around Cape Town, South Africa. The questions in the survey were designed to gain information, and to provide information on the latent constructs of the behavioural framework constructed in "Electric vehicle adoption intention among paratransit owners and drivers in South Africa". The data were used in the aforementioned paper to shed light on the attitudes, barriers, and enablers to EV adoption in the paratransit sector, providing insights for targeted interventions and promoting sustainable mobility. The data can be re-used for more in-depth studies of, as well as comparative studies assessing the socio-economic profiles and EV perceptions of paratransit owners and drivers in vs. other regions, and longitudinal studies benchmarking changes in EV perceptions in these demographics over time. Comparative studies could identify regional variations, cultural influences, and policy implications for promoting EV adoption in different contexts, and longitudinal studies can assess the effectiveness of interventions, policy changes, or technological advancements on EV adoption in the paratransit sector over time.

Perceptions of the seriousness of major public health problems during the COVID-19 pandemic in seven middle-income countries.

INTRODUCTION: Public perception of the seriousness of the COVID-19 pandemic compared to six other major public health problems (alcoholism and drug use, HIV/AIDS, malaria, tuberculosis, lung cancer and respiratory diseases caused by air pollution and smoking, and water-borne diseases like diarrhea) is unclear. We designed a survey to examine this issue using YouGov's internet panels in seven middle-income countries in Africa, Asia, and Latin America in early 2022. METHODS: Respondents rank ordered the seriousness of the seven health problems using a repeated best-worst question format. Rank-ordered logit models allow comparisons within and across countries and assessment of covariates. RESULTS: In six of the seven countries, respondents perceived other respiratory illnesses to be a more serious problem than COVID-19. Only in Vietnam was COVID-19 ranked above other respiratory illnesses. Alcoholism and drug use was ranked the second most serious problem in the African countries. HIV/AIDS ranked relatively high in all countries. Covariates, particularly a COVID-19 knowledge scale, explained differences within countries; statistics about the pandemic were highly correlated with differences in COVID-19's perceived seriousness. CONCLUSIONS: People in the seven middle-income countries perceived COVID-19 to be serious (on par with HIV/AIDS) but not as serious as other respiratory illnesses. In the African countries, respondents perceived alcoholism and drug use as more serious than COVID-19. Our survey-based approach can be used to quickly understand how the threat of a newly emergent disease, like COVID-19, fits into the larger context of public perceptions of the seriousness of health problems.

We were curious what people in different countries thought about the seriousness of COVID-19 compared to other health problems. We designed a survey, and hired YouGov, a survey research firm, to administer it in seven countries in Africa, Asia, and Latin America in early 2022. Respondents answered the questions on their computer, tablets, or smart phones. Their answers revealed that in most countries respiratory illnesses were perceived to be a more serious problem than COVID-19. In Africa people felt that alcoholism and drug use were also more serious than COVID-19. These findings are important because they show that people still care about the health problems they were facing before the pandemic, which is useful information for healthcare providers.

Development and evaluation of a fidelity tool in a post-discharge responsive parenting intervention program for very preterm born children.

The TOP program is a fully implemented responsive parenting intervention for very preterm born infants. Fidelity monitoring of interventions is important for preserving program adherence, impact outcomes and to make evidence-based adaptations. The aim of this study was to develop a fidelity tool for the TOP program following an iterative and co-creative process and subsequently evaluate the reliability of the tool. Three consecutive phases were carried out. Phase I: Initial development and pilot testing two methods namely self-report and video based observation. Phase II: Adaptations and refinements. Phase III: Evaluation of the psychometric properties of the tool based on 20 intervention videos rated by three experts.The interrater reliability of the adherence and competence subscales was good (ICC.81 to .84) and varied from moderate to excellent for specific items (ICC between .51 and .98). The FITT displayed a high correlation (Spearman's rho.79 to.82) between the subscales and total impression item. The co-creative and iterative process resulted in a clinical useful and reliable tool for evaluating fidelity in the TOP program. This study offers insights in the practical steps in the development of a fidelity assessment tool which can be used by other intervention developers.

Neurodevelopmental Outcomes at Two Years' Corrected Age of Very Preterm Infants after Implementation of a Post-Discharge Responsive Parenting Intervention Program (TOP Program).

OBJECTIVE: To compare neurodevelopmental outcomes at 2 years corrected age (CA) between infants born very preterm (VP) who did or did not receive a postdischarge responsive parenting intervention (Transmural developmental support for very preterm infants and their parents [TOP program]) between discharge home and 12 months' CA. STUDY DESIGN: The Systemic Hydrocortisone to Prevent Bronchopulmonary Dysplasia (SToP-BPD) study showed no differences between treatment groups in motor and cognitive development using the Dutch Bayley Scales of Infant Development and behavior using the Child Behavior Checklist at 2 years' CA. During its study period, the TOP program was gradually scaled up nationwide in the same population, providing an opportunity to evaluate the effect of this program on neurodevelopmental outcome, after adjusting for baseline differences. RESULTS: Among 262 surviving VP infants in the SToP-BPD study, 35% received the TOP program. Infants in the TOP group had a significantly lower incidence of a cognitive score <85 (20.3% vs 35.2%; adjusted absolute risk reduction: -14.1% [95% CI: -27.2 to -1.1]; P = .03), and a significantly higher mean cognitive score (96.7 ± 13.8), compared with the non-TOP group (92.0 ± 17.5; crude mean difference: 4.7 [95% CI: 0.3 to 9.2]; P = .03). No significant differences were found on motor scores. For behavior problems, a small but statistically significant effect for anxious/depressive problems was found in the TOP group (50.5 vs 51.2; P = .02). CONCLUSIONS: VP infants supported by the TOP program from discharge until 12 months' CA had better cognitive function at 2 years' CA. This study demonstrates a sustained positive effect of the TOP program in VP infants.

Factors Associated With Walking Adaptability and Its Relationship With Falling in Polio Survivors.

OBJECTIVE: To explore factors associated with walking adaptability and associations between walking adaptability and falling in polio survivors. DESIGN: Cross-sectional study. SETTING: Outpatient expert polio clinic. PARTICIPANTS: Polio survivors (N=46) who fell in the previous year and/or reported fear of falling. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Walking adaptability was assessed on an interactive treadmill and operationalized as variable target-stepping and reactive obstacle avoidance performance. Further, we collected walking speed and assessed leg muscle strength, balance performance (Berg Balance Scale and Timed-Up-and-Go Test), balance confidence (Activities-specific Balance Confidence scale), ambulation level, orthosis use, fear of falling, and number of falls in the previous year. RESULTS: With walking speed included as a covariate, muscle weakness of the most affected leg and balance confidence explained 54% of the variance in variable target-stepping performance. For reactive obstacle avoidance performance, muscle weakness of the most affected leg and knee extensor strength of the least affected leg explained 32% of the variance. Only target-stepping performance was significantly related to the number of falls reported in the previous year (R2=0.277, P<.001) and mediated the relation between leg muscle weakness and balance confidence with falling. CONCLUSION: Our exploratory study suggests that leg muscle weakness and reduced balance confidence limit walking adaptability in polio survivors. Because poorer target stepping rather than obstacle avoidance performance was associated with falling, our results indicate that a limited ability to ensure safe foot placement may be a fall risk factor in this group. These findings should be confirmed in a larger sample.

Sexual health and closeness in couples coping with advanced cancer: Results of a multicenter observational study (eQuiPe).

BACKGROUND: Cancer and its treatment can severely affect sexual health. It is unknown how this may relate to the feelings of closeness between patients and their partners. AIM: To assess the association between sexual health and closeness in the relationship in couples coping with advanced cancer. DESIGN: This study was part of a prospective multicentre longitudinal observational cohort study on experienced quality of care and quality of life in patients with advanced cancer and their relatives (eQuiPe). SETTING/PARTICIPANTS: Baseline data regarding sexual health and closeness in people with advanced cancer and their partners. RESULTS: Out of the 566 dyads, 14 were same-sex couples. Especially male partners showed an interest in sex, but more than half of all patients and partners were not sexually active. Approximately one third experienced sexual dysfunction to be a problem but did not seek specialized support (<10%). There was a positive association between own sexual satisfaction and feelings of closeness in the relationship, which was stronger for partners compared to patients (p < 0.001). Sexual satisfaction of the other person was also related to own feelings of closeness (p = 0.003). CONCLUSIONS: Couples coping with advanced cancer clearly face challenges regarding sexual health but are not likely to seek specialized support. When discussing sexual health, it is crucial that health care professionals pay attention to the aspects of sexual health that may contribute to feeling close to each other and suggest specialized care if necessary. TRIAL REGISTRATION: The eQuiPe study is registered as NTR6584 in the Netherlands Trial Register.

Therapeutic Drug Monitoring of Endoxifen for Tamoxifen Precision Dosing: Feasible in Patients with Hormone-Sensitive Breast Cancer.

BACKGROUND: Endoxifen is the most important active metabolite of tamoxifen. Several retrospective studies have suggested a minimal or threshold endoxifen systemic concentration of 14-16 nM is required for a lower recurrence rate. The aim of this study was to investigate the feasibility of reaching a predefined endoxifen level of ≥ 16 nM (5.97 ng/mL) over time using therapeutic drug monitoring (TDM). METHODS: This prospective open-label intervention study enrolled patients who started treatment with a standard dose of tamoxifen 20 mg once daily for early breast cancer. An outpatient visit was combined with a TDM sample at 3, 4.5, and 6 months after initiation of the tamoxifen treatment. The tamoxifen dose was escalated to a maximum of 40 mg if patients had an endoxifen concentration < 16 nM. The primary endpoint of the study was the percentage of patients with an endoxifen level ≥ 16 nM at 6 months after the start of therapy compared with historical data, in other words, 80% of patients with endoxifen levels ≥ 16 nM with standard therapy. RESULTS: In total, 145 patients were included. After 6 months, 89% of the patients had endoxifen levels ≥ 16 nM, compared with a literature-based 80% of patients with endoxifen levels ≥ 16 nM at baseline (95% confidence interval 82-94; P = 0.007). In patients with an affected CYP2D6 allele, it was not always feasible to reach the predefined endoxifen level of ≥ 16 nM. No increase in tamoxifen-related adverse events was reported after dose escalation. CONCLUSION: This study demonstrated that it is feasible to increase the percentage of patients with endoxifen levels ≥ 16 nM using TDM. TDM is a safe strategy that offers the possibility of nearly halving the number of patients with endoxifen levels < 16 nM.

Mental health monitoring in parents after very preterm birth.

AIM: To evaluate parental mental health monitoring during follow-up care for very preterm (VPT) infants, describe symptoms of anxiety and depression and risk factors for mothers and fathers at 1 and 12 months of corrected age. METHODS: Parents completed the Hospital Anxiety and Depression Scale (HADS). Psychological symptoms and risk factors were analysed within and between mothers and fathers. RESULTS: In 4 years, the monitoring reached 1260 (48%) families. Of these, 693 mothers and 340 fathers (300 couples) completed the HADS twice. At 1 month, 22% and 15% of the mothers and 10% and 9% of the fathers, respectively, reported elevated symptoms of anxiety and depression. At 12 months, these rates were significantly reduced to 14% and 9% for mothers and 5% and 4% for fathers respectively. Within couples, anxiety and depression were positively associated. At 12 months, in 20% of the couples, one or both parents reported elevated symptoms. Risk factors were length of hospital stay, migration background, educational level and employment status. CONCLUSION: The mental health of parents of VPT infants improved, but elevated symptoms were still observed in 17% of included families after one year. Acknowledging and remediating parental mental health remain essential during follow-up care.

Development and nationwide implementation of a postdischarge responsive parenting intervention program for very preterm born children: The TOP program.

A previous randomized controlled trial has suggested the effectiveness of a Dutch postdischarge responsive parenting program for very preterm (VPT) infants, indicating that nationwide implementation was justified. This paper describes the development and nationwide implementation of the intervention, known as the TOP program, which consisted of three phases. In the preparation phase (2006-2010), a theory of change and the structure of the TOP program were developed, and funding for phase two, based on a positive Business Case, was obtained. In the pilot implementation phase (2010-2014), intervention strategies were developed for a real-world setting, capacity and adoption were increased, systematic evaluations were incorporated, and sustained funding was obtained. In the full-implementation phase (2014-2019), all Dutch Healthcare Insurers reimbursed the TOP program, enabling VPT infants to participate in the program without charge. By 2018, the number of interventionists that provided the TOP program had increased from 37 to 91, and all level III hospitals and 65% of regional hospitals in the Netherlands referred VPT infants. Currently, the program reaches 70% of the Dutch target population and parental satisfaction with the TOP program is high. After a 12-year implementation period, the TOP program forms part of routine care in the Netherlands.

Un previo ensayo controlado al azar ha sugerido la eficacia de un programa holandés sobre la crianza sensible para infantes muy prematuros (VPT) posterior al momento en que se les dio de alta, indicando que la implementación a lo largo de toda la nación era justificada. Este artículo describe el desarrollo y la implementación a nivel de toda la nación de la intervención, conocida como el programa ToP, el cual consistía de tres fases. En la fase de preparación (2006-2010), se desarrollaron una teoría de cambio y la estructura del programa ToP, y se obtuvieron los fondos para la fase dos, con base en un Caso de Negocios (BC) positivo. En la fase piloto de implementación (2010-2014), se desarrollaron estrategias de intervención para un escenario del mundo real, se aumentaron la capacidad y la adopción, se incorporaron evaluaciones sistemáticas y se obtuvieron fondos para mantener el programa. En la fase de implementación completa (2014-2019), todas las Aseguradoras Holandesas del Sector Salud reembolsaron el costo del programa ToP, permitiéndoles a los infantes VPT participar en el programa sin costo alguno. Para 2018, el número de practicantes de la intervención que prestaban el servicio del programa ToP había aumentado de 37 a 91, y todos los hospitales del nivel III y 65% de los hospitales regionales en Holanda refirieron los infantes VPT al programa. Actualmente, el programa llega a 70% de la población holandesa para la cual está destinado y la satisfacción de los padres con el programa ToP es alta. Después de un período de implementación de 12 años, el programa ToP forma parte del cuidado de salud rutinario en Holanda.

Un essai contrôlé randomisé précédent a suggéré l'efficacité d'un programme hollandais de sensibilité de parentage après la sortie de l'hôpital pour les nourrissons grands prématurés (GP ici en français), indiquant qu'une mise en œuvre au niveau national était justifiée. Cet article décrit le développement et la mise en œuvre au niveau national de l'intervention, connue en tant que ToP program, qui a consisté en trois phases. Dans la phase de préparation (2006-2010), une théorie du changement et la structure du programme ToP a été développée, et le financement pour la phase deux, basée sur une Etude de Cas positive, a été sécurisé. Dans la phase pilote d'implémentation (2010-2014) des stratégies d'intervention ont été développées pour un contexte réel, la capacité et l'adoption ont été augmentées, les évaluations systématiques ont été incorporées, et un financement durable a été sécurisé. Dans la pleine phase de mise en œuvre (2014-1029), tous les Assurances Santé Hollandaises ont remboursé le programme ToP, permettant aux nourrissons GP de participer au programme sans coût. En 2018 le nombre de prestataires qui offraient le programme ToP a augmenté de 37 à 91, et tous les hôpitaux de niveau III ainsi que 65% des hôpitaux régionaux aux Pays Bas ont envoyé les nourrissons GP au programme. En ce moment le programme atteint 70% de la population cible hollandaise et la satisfaction parentale avec le programme ToP est élevée. Après une période de mise en œuvre de 12 ans le programme ToP fait partie des soins de routine aux Pays Bas.

Influence of green tea consumption on endoxifen steady-state concentration in breast cancer patients treated with tamoxifen.

BACKGROUND: Many cancer patients use additional herbs or supplements in combination with their anti-cancer therapy. Green tea-active ingredient epigallocatechin-3-gallate (EGCG)-is one of the most commonly used dietary supplements among breast cancer patients. EGCG may alter the metabolism of tamoxifen. Therefore, the aim of this study was to investigate the influence of green tea supplements on the pharmacokinetics of endoxifen; the most relevant active metabolite of tamoxifen. METHODS: In this single-center, randomized cross-over trial, effects of green tea capsules on endoxifen levels were evaluated. Patients treated with tamoxifen for at least 3 months were eligible for this study. After inclusion, patients were consecutively treated with tamoxifen monotherapy for 28 days and in combination with green tea supplements (1 g twice daily; containing 300 mg EGCG) for 14 days (or vice versa). Blood samples were collected on the last day of monotherapy or combination therapy. Area under the curve (AUC0-24h), maximum concentration (Cmax) and minimum concentration (Ctrough) were obtained from individual plasma concentration-time curves. RESULTS: No difference was found in geometric mean endoxifen AUC0-24h in the period with green tea versus tamoxifen monotherapy (- 0.4%; 95% CI - 8.6 to 8.5%; p = 0.92). Furthermore, no differences in Cmax (- 2.8%; - 10.6 to 5.6%; p = 0.47) nor Ctrough (1.2%; - 7.3 to 10.5%; p = 0.77) were found. Moreover, no severe toxicity was reported during the whole study period. CONCLUSIONS: This study demonstrated the absence of a pharmacokinetic interaction between green tea supplements and tamoxifen. Therefore, the use of green tea by patients with tamoxifen does not have to be discouraged.

Pharmacokinetics of Sublingually Delivered Fentanyl in Head and Neck Cancer Patients Treated with Curatively Aimed Chemo or Bioradiotherapy.

Over 90% of patients treated for head and neck cancer with curatively aimed chemo or bioradiotherapy will develop painful mucositis and xerostomia. Sublingually delivered fentanyl (SDL) is a rapid acting opioid to treat breakthrough pain. It is unclear how SDL is absorbed by the mucosa of these patients. Therefore, the aim of this study was to investigate the effects of mucositis and xerostomia on the absorption of SDL. Thirteen patients who received chemo or bioradiotherapy (RT), were given a single dose of fentanyl: Before start of RT, 3 and 6 weeks after start of RT, and 6 weeks after finishing RT. Pharmacokinetic samples were taken. The primary endpoint was the relative difference (RD) between systemic exposure to fentanyl (area under the curve; AUC) at baseline (AUCbaseline) and fentanyl AUC in the presence of mucositis grade ≥2. The secondary endpoint was the RD between AUCbaseline and fentanyl AUC in the presence of xerostomia, which were analyzed by means of a paired t-test on log-transformed data. Mucositis resulted in a 12.7% higher AUC (n = 13; 95% CI: -10.7% to +42.2%, p = 0.29) compared to baseline levels and xerostomia resulted in a 22.4% lower AUC (n = 8; 95% CI: -51.9% to +25.3%, p = 0.25) compared to baseline levels. Mucositis grade ≥2 or xerostomia caused by chemo or bioradiotherapy does not significantly alter the systemic exposure to SDL. Patients with pain during and after chemo or bioradiotherapy may be safely treated with SDL.

Effects of smoking and body mass index on the exposure of fentanyl in patients with cancer.

The transdermal fentanyl patch is widely used to treat cancer-related pain despite its wide inter- and intrapatient variability in pharmacokinetics. The aim of this study was to investigate whether smoking and body size (i.e. body mass index) influence fentanyl exposure in patients with cancer. These are factors that typically change during treatment and disease trajectories. We performed an explorative cohort study in patients with cancer using transdermal fentanyl patches (Durogesic®), by taking a blood sample for pharmacokinetic analysis one day after applying a patch in patients with a stable fentanyl dose. A total of 88 patients were evaluable. Although no statistically significant difference was found, the plasma concentrations of non-smokers was 28% (95% CI [-14%; +89-%]) higher than those of smokers normalizing for a dose of 25µg/min. Patients with a low BMI (< 20 kg/m2) had almost similar (10% (95% CI [-39%; +97%]) higher) plasma concentrations compared to patients with a high BMI (> 25 kg/m2). A wider variation in fentanyl plasma concentrations was found in this study than anticipated. Due to this variation, studies in larger patient cohorts are needed to further investigate the effect of smoking on plasma concentration of fentanyl and thereby clarify the clinical significance of our findings.

Feasibility of a Preventive Parenting Intervention for Very Preterm Children at 18 Months Corrected Age: A Randomized Pilot Trial.

OBJECTIVE: To evaluate the feasibility and potential efficacy of an age-appropriate additional parenting intervention for very preterm born toddlers. STUDY DESIGN: In a randomized controlled pilot study, 60 of 94 eligible very preterm born children who had received a responsive parenting intervention in their first year were randomized to usual care or the additional intervention, consisting of 4-6 home visits between 18 and 22 months' corrected gestational age (CA). Parents were supported to responsively interact during increasingly complex daily activities and play. Parental satisfaction with the intervention was evaluated with a questionnaire. At baseline and 24 months CA, parents completed the Infant Toddler Social and Emotional Assessment, the Ages and Stages Questionnaire, and the Dutch Schlichting Lexilist for receptive language. At 24 months CA, motor, and cognitive development was measured by the Bayley Scales of Infant and Toddler Development, Third Edition Dutch version, and parent-child interaction was evaluated by the Emotional Availability Scales. RESULTS: Parental compliance and satisfaction with the intervention was high. Effect sizes (after correction for baseline variables) were small for internalizing and competence behavior, receptive language, and problem solving; medium for cognitive development and parent-child interaction; and large for externalizing and dysregulation behavior and motor development. CONCLUSION: After a postdischarge intervention during the first year, an additional responsive parenting support at toddler-age is feasible and associated with positive outcomes in a broad array of parental and child outcome measures.

Rethinking preventive post-discharge intervention programmes for very preterm infants and their parents.

Post-discharge preventive intervention programmes with involvement of the parent may support the resilience and developmental outcomes of infants born very preterm. Randomized controlled trials of home-based family-centred intervention programmes in very preterm infants that aimed to improve cognitive outcome, at least at age two, were selected and updated on the basis of a recent systematic review to compare their content and effect over time to form the basis of a narrative review. Six programmes were included in this narrative review. Four of the six programmes led to improved child cognitive and/or motor development. Two programmes, which focused primarily on responsive parenting and development, demonstrated improved cognitive outcome up till 5 years after completion of the programme. The programmes that also focused on maternal anxiety remediation led to improved maternal mental well-being, along with improved child behaviour, in one study - even at 3 years after completion of the programme. The magnitude of the effects was modest. Family-centred preventive intervention programmes that aim at improvement of child development should be continued after discharge home to improve the preterm child's resilience. Programmes may be most effective when they support the evolvement of a responsive parent-infant relationship over time, as well as the parent's well-being.

Deficits in vision and visual attention associated with motor performance of very preterm/very low birth weight children.

AIM: To extend understanding of impaired motor functioning of very preterm (VP)/very low birth weight (VLBW) children by investigating its relationship with visual attention, visual and visual-motor functioning. METHODS: Motor functioning (Movement Assessment Battery for Children, MABC-2; Manual Dexterity, Aiming & Catching, and Balance component), as well as visual attention (attention network and visual search tests), vision (oculomotor, visual sensory and perceptive functioning), visual-motor integration (Beery Visual Motor Integration), and neurological status (Touwen examination) were comprehensively assessed in a sample of 106 5.5-year-old VP/VLBW children. Stepwise linear regression analyses were conducted to investigate multivariate associations between deficits in visual attention, oculomotor, visual sensory, perceptive and visual-motor integration functioning, abnormal neurological status, neonatal risk factors, and MABC-2 scores. RESULTS: Abnormal MABC-2 Total or component scores occurred in 23-36% of VP/VLBW children. Visual and visual-motor functioning accounted for 9-11% of variance in MABC-2 Total, Manual Dexterity and Balance scores. Visual perceptive deficits only were associated with Aiming & Catching. Abnormal neurological status accounted for an additional 19-30% of variance in MABC-2 Total, Manual Dexterity and Balance scores, and 5% of variance in Aiming & Catching, and neonatal risk factors for 3-6% of variance in MABC-2 Total, Manual Dexterity and Balance scores. CONCLUSION: Motor functioning is weakly associated with visual and visual-motor integration deficits and moderately associated with abnormal neurological status, indicating that motor performance reflects long term vulnerability following very preterm birth, and that visual deficits are of minor importance in understanding motor functioning of VP/VLBW children.
