RESUMO

OBJECTIVE: Curative treatment of low-risk prostate cancer (LR-PCa) does not improve cancer specific survival and active surveillance (AS) is recommended. Although AS is cost-effective and reduces treatment-related complications, it requires psychosocial support. Research on psychosocial interventions specifically focused on men undergoing AS is limited. Aim of this study is to reach consensus amongst relevant stakeholders on selecting interventions offering psychosocial support to PCa patients during AS. METHODS: In accordance with the RAND/UCLA method, a modified Delphi approach was used to establish consensus on selecting interventions. During phase one, interventions were identified through a literature review and open survey among all participants. During phase two, three consensus rounds were conducted to rate potential interventions and obtain statistical consensus. The IQ healthcare consensus tool was used to calculate statistical consensus. RESULTS: After the first consensus round, 31 participants scored individual interventions on relevance using a 9-point Likert scale resulting in the selection of six interventions. During the second consensus round 13 discussion items were reviewed during a focus group. After the third consensus round, seven additional interventions were selected by 23 participants. CONCLUSIONS: In total, 13 interventions were selected for inclusion in a support program. This included four interventions within the domain information and education, three within coping and support, one intervention within physical wellbeing and four within the domain lifestyle.

RESUMO

PURPOSE: Living with untreated prostate cancer (PCa) may cause anxiety and uncertainty in men undergoing active surveillance (AS). Developing a psychosocial support program for such patients might promote psychosocial well-being and patient engagement. This review aims to identify interventions with the potential to influence the psychosocial burden of prostate cancer patients undergoing AS. METHODS: A scoping review was conducted in accordance with the PRISMA Extension for Scoping Reviews Checklist. A systematic search was conducted in six databases and included publications dating from 2009. All available and eligible evidence was included in this review. RESULTS: After screening 2824 articles, 12 studies were included in the review: nine quantitative, one qualitative, and two mixed method papers. The relative strength of these studies was limited and the quality of most was moderate. CONCLUSIONS: The described interventions can be categorized into three major themes: information and education, coping and (psycho)social support, and lifestyle. Psychosocial support for men undergoing AS should entail involvement of family and spouse during the decision-making process, tailored information about PCa treatments, risks, benefits, protocols, lifestyle adjustments, and complementary and alternative medicine. Assessment and promotion of effective coping and self-management strategies are recommended. Healthcare providers should actively promote physical activity and nutritional improvements. Physical activity programs may also be helpful in facilitating peer support, which is especially important for men with limited social support. Future research should investigate combining interventions to increase efficacy and optimize supportive care during AS.

RESUMO

A major event in the human life course is the move to a care center. In order for this transition to be successful, it is important that a care center creates the right conditions to achieve that residents feel at home and satisfied. The aim of this study is to investigate which characteristics are important for this,  according to the employees of care centers in the Netherlands. First a limited list of 15 characteristics has been constructed on the basis of literature research. With the help of the Delphi method, in three rounds, employees of Dutch care institutions were then asked about the importance of these characteristics for a successful adaptation of residents to the new living environment and they were asked to provide additional comments. Based on this, characteristics have been reformulated, added or removed. The result after the third round was a high degree of agreement on the characteristics that were considered (very) important. The attribute 'respect', scored in all three rounds the highest, followed directly by the characteristics 'approach' and 'safety'. There was a high degree of agreement about the most important characteristics between the different job levels (such as employee care or supervisor).

RESUMO

OBJECTIVE: This study explored the perspectives of child oncology professionals and parents about the attention professionals should give to the parent couple relationship during treatment of the child. METHODS: We employed a qualitative research design, framed within the approach of consensual qualitative research (CQR), gathering data from four focus groups with 20 professionals and from nine in-depth interviews with 16 parents. Thematic analysis of the focus group and interview data was done with MaxQda software, using two coders and member checks to strengthen confidence in the analysis. FINDINGS: Both professionals and parents talked about an elevated tension in the partner relationship during oncology treatment of the child. However, explicit attention to the partner relationship in this context felt inappropriate to professionals and parents. All emphasized the importance of the professional helpers' openness to conversation and an attuned response to the parental couple relationship. CONCLUSION: During treatment, the child is the primary focus for parents and professionals. The parents' focus on supporting their child makes talking about their own emotions or about issues in the partner relationship potentially disruptive and unhelpful. Therefore, it is crucial for professionals to support the parents in their parents' role, but with an openness to converse about issues in the partner relationship at the moments when these issues might threaten their focus on the child.

RESUMO

BACKGROUND: Smoking cessation after developing coronary heart disease improves disease prognosis more than any other treatment. However, many cardiac patients continue to smoke after hospital discharge. OBJECTIVE: The aim of this study was to investigate factors associated with the intention to (permanently) abstain from smoking among cardiac rehabilitation patients 2 to 4 weeks after discharge from hospital. METHODS: A cross-sectional survey was conducted among 149 cardiac rehabilitation patients recruited from 2 cardiac rehabilitation centers in The Netherlands 2 to 4 weeks after hospital discharge, at the start of the cardiac rehabilitation period. Psychosocial cognitions including attitude toward nonsmoking, social influence, and self-efficacy were measured with a standardized and validated Dutch questionnaire based on the Attitude-Social Influence-Self-efficacy model. Anxiety was measured using the shortened version of the State-Trait Anxiety Inventory. Craving for cigarettes was assessed with 6 items measuring the urge to smoke. Intention toward nonsmoking was assessed with 2 visual analog scales indicating the strength and probability of the intention to permanently refrain from smoking. RESULTS: Of all patients, 31% still smoked after hospital discharge. The smokers had a lower self-efficacy and intention to abstain from smoking and reported higher craving. Logistic regression analyses revealed that attitudes that embraced the advantages of not smoking, self-efficacy, and craving were significantly related to the intention to (permanently) abstain from smoking, whereas social influence and anxiety were not. Actual smoking behavior moderated the relation between self-efficacy and intention: only the quitters showed a significant positive relation. Anxiety did not moderate the relationship between psychosocial cognitive factors and intention. CONCLUSIONS: The intention to (permanently) abstain from smoking, measured 2 to 4 weeks after hospitalization for a cardiac event, predominantly depends on attitude, self-efficacy, and craving. Interventions aimed at smoking cessation among cardiac rehabilitation patients should focus on these factors.

RESUMO

OBJECTIVE: To study whether pregnancy-related lumbopelvic pain outcomes at 36 weeks of gestation can be predicted by psychological determinants earlier in pregnancy. DESIGN: Prospective cohort study. SETTING: Nine midwifery practices in different regions of the Netherlands. POPULATION: A cohort of 223 low-risk pregnant women in the Netherlands was followed from week 12 of gestation until 36 weeks of gestation. METHODS: Both psychological determinants and lumbopelvic pain symptoms were investigated with a set of questionnaires at 12, 24 and 36 weeks of gestation. Psychological determinants were measured with the Perceived Stress Scale (PSS), the Symptom Checklist-90-Revised (SCL-90), the Pregnancy-related Anxiety Questionnaire (PRAQ), and the Utrecht Coping List (UCL). Lumbopelvic pain outcomes were measured with the Pregnancy Mobility Index (PMI) and the Overall Complaints Index (OCI). MAIN OUTCOME MEASURES: Lumbopelvic pain symptoms and their impact at 36 weeks of gestation. RESULTS: There was a significant increase in scores on both the PMI and OCI across the three sampling occasions in pregnancy. Lumbopelvic pain outcomes showed significant associations with the psychological determinants perceived stress and recently perceived psychological and physical distress at all three times during pregnancy. Pregnancy-related anxiety was not a significant predictor of lumbopelvic pain outcomes, neither was coping. CONCLUSIONS: Lumbopelvic pain symptoms and their impact on daily activities at 36 weeks of gestation can be predicted by psychological determinants earlier in pregnancy; the combination of perceived stress and physical disability at 24 weeks of pregnancy seems to be the best predictor of disability in later pregnancy.

RESUMO

OBJECTIVE: To study the experiences, considerations, and motivations of patients with endometriosis in the decision-making process for deep endometriosis (DE) treatment options. DESIGN: Qualitative study using semi-structured in-depth focus group methodology. SETTING: University medical center. PATIENT(S): A total of 19 Dutch women diagnosed with DE between 27 and 47 years of age. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Focus group topics were disease impact and motives for treatment, expectations of the treatment process, and important factors in the decision process. RESULT(S): Women reported that pain, fertility, and strong fear of complications are important decisive factors in the treatment process. The goal of conceiving a child is considered important, however, sometimes doctors emphasize this topic too much. It emerged that complication counseling is frequently about surgical complications, whereas side effects of hormonal treatments are neglected. Shared decision making and information about treatment options, complications, and side effects are not always optimal, making it difficult to make a well-considered choice. Despite negative experiences encountered after surgery, the positive effect of surgery ensures that most women do not regret their choice. CONCLUSION(S): In the treatment decision process for patients with DE, pain is almost always the most important decisive factor. The wish to conceive and strong fear of complications can change this choice. Doctors should understand the importance of fertility for the majority of women, but, also, if this is not considered paramount, respect that view. To improve shared decision making, exploration of treatment goals, training of healthcare providers, and better patient information provision are desirable.

RESUMO

Socioeconomic status (SES) is associated with many health issues and health-compromising behaviour (HCB). Most research is based on objective indicators of SES, even though subjective SES, someone's perception of their social standing, is also related to health. Moreover, perceptions of health and HCB might also be of importance. Therefore, this study examined the relationship between both objective and subjective SES and perceived health and HCB respectively, and the role of perceptions of HCB. 326 respondents completed measures of objective and subjective SES, perceived health, HCB and perceptions of HCB. Results showed objective and subjective SES were related to perceived health. Only subjective SES was related to HCB, while for objective SES a moderating effect of perceiving HCB as typically high or low SES was found. Not only objective SES, but especially perceptions of SES and HCB are associated with someone feeling healthy and engaging in HCB. Health interventions should try to tackle perceptions of SES and HCB, either by invalidating current SES related perceptions or by emphasizing new healthy perceptions.

RESUMO

In this study, the performance of various methods for generating quantitative parametric images of dynamic 11C-phenytoin PET studies was evaluated. Methods: Double-baseline 60-min dynamic 11C-phenytoin PET studies, including online arterial sampling, were acquired for 6 healthy subjects. Parametric images were generated using Logan plot analysis, a basis function method, and spectral analysis. Parametric distribution volume (VT) and influx rate (K1) were compared with those obtained from nonlinear regression analysis of time-activity curves. In addition, global and regional test-retest (TRT) variability was determined for parametric K1 and VT values. Results: Biases in VT observed with all parametric methods were less than 5%. For K1, spectral analysis showed a negative bias of 16%. The mean TRT variabilities of VT and K1 were less than 10% for all methods. Shortening the scan duration to 45 min provided similar VT and K1 with comparable TRT performance compared with 60-min data. Conclusion: Among the various parametric methods tested, the basis function method provided parametric VT and K1 values with the least bias compared with nonlinear regression data and showed TRT variabilities lower than 5%, also for smaller volume-of-interest sizes (i.e., higher noise levels) and shorter scan duration.

RESUMO

Studies in rodents suggest that flumazenil is a P-glycoprotein substrate at the blood-brain barrier. This study aimed to assess whether [11C]flumazenil is a P-glycoprotein substrate in humans and to what extent increased P-glycoprotein function in epilepsy may confound interpretation of clinical [11C]flumazenil studies used to assess gamma-aminobutyric acid A receptors. Nine drug-resistant patients with epilepsy and mesial temporal sclerosis were scanned twice using [11C]flumazenil before and after partial P-glycoprotein blockade with tariquidar. Volume of distribution, nondisplaceable binding potential, and the ratio of rate constants of [11C]flumazenil transport across the blood-brain barrier (K1/k2) were derived for whole brain and several regions. All parameters were compared between pre- and post-tariquidar scans. Regional results were compared between mesial temporal sclerosis and contralateral sides. Tariquidar significantly increased global K1/k2 (+23%) and volume of distribution (+10%), but not nondisplaceable binding potential. At the mesial temporal sclerosis side volume of distribution and nondisplaceable binding potential were lower in hippocampus (both ∼-19%) and amygdala (both ∼-16%), but K1/k2 did not differ, suggesting that only regional gamma-aminobutyric acid A receptor density is altered in epilepsy. In conclusion, although [11C]flumazenil appears to be a (weak) P-glycoprotein substrate in humans, this does not seem to affect its role as a tracer for assessing gamma-aminobutyric acid A receptor density.

RESUMO

OBJECTIVES: To determine the influence of instrumental, emotional and informative support on the quality of life of former intensive care unit (ICU) patients and to establish their preferred sources of social support. RESEARCH METHODOLOGY: In a cross-sectional survey, former intensive care patients (n=88) completed the "social support interactions/discrepancies list", the "RAND-36 Health Survey" and reported their preferred sources of the different types of social support. SETTING: A 35 bed intensive care unit in the Radboudumc university hospital in the Netherlands. MAIN OUTCOME MEASURES: Psychological, physical and social domains of quality of life and patient preferences regarding sources of social support. RESULTS: Instrumental and emotional support show a buffering effect on the physical dimension of the quality of life. The discrepancies between the expected and the received instrumental, informative and emotional support have a negative influence on psychological quality of life. Former ICU patients prefer receiving social support from family members rather than friends, professional caregivers or fellow former ICU patients. CONCLUSION: This study emphasises the buffering effect of social support on diminished quality of life in former intensive care patients. It is suggested that hospitals provide an intensive care after-care programme including both patients and relatives to help fulfilling this need for social support.

RESUMO

UNLABELLED: The overexpression of P-glycoprotein (Pgp) is thought to be an important mechanism of pharmacoresistance in epilepsy. Recently, (11)C-phenytoin has been evaluated preclinically as a tracer for Pgp. The aim of the present study was to assess the optimal plasma kinetic model for quantification of (11)C-phenytoin studies in humans. METHODS: Dynamic (11)C-phenytoin PET scans of 6 healthy volunteers with arterial sampling were acquired twice on the same day and analyzed using single- and 2-tissue-compartment models with and without a blood volume parameter. Global and regional test-retest (TRT) variability was determined for both plasma to tissue rate constant (K1) and volume of distribution (VT). RESULTS: According to the Akaike information criterion, the reversible single-tissue-compartment model with blood volume parameter was the preferred plasma input model. Mean TRT variability ranged from 1.5% to 16.9% for K1 and from 0.5% to 5.8% for VT. Larger volumes of interest showed better repeatabilities than smaller regions. A 45-min scan provided essentially the same K1 and VT values as a 60-min scan. CONCLUSION: A reversible single-tissue-compartment model with blood volume seems to be a good candidate model for quantification of dynamic (11)C-phenytoin studies. Scan duration may be reduced to 45 min without notable loss of accuracy and precision of both K1 and VT, although this still needs to be confirmed under pathologic conditions.

RESUMO

UNLABELLED: Overexpression of the multidrug efflux transport P-glycoprotein may play an important role in pharmacoresistance. (11)C-laniquidar is a newly developed tracer of P-glycoprotein expression. The aim of this study was to develop a pharmacokinetic model for quantification of (11)C-laniquidar uptake and to assess its test-retest variability. METHODS: Two (test-retest) dynamic (11)C-laniquidar PET scans were obtained in 8 healthy subjects. Plasma input functions were obtained using online arterial blood sampling with metabolite corrections derived from manual samples. Coregistered T1 MR images were used for region-of-interest definition. Time-activity curves were analyzed using various plasma input compartmental models. RESULTS: (11)C-laniquidar was metabolized rapidly, with a parent plasma fraction of 50% at 10 min after tracer injection. In addition, the first-pass extraction of (11)C-laniquidar was low. (11)C-laniquidar time-activity curves were best fitted to an irreversible single-tissue compartment (1T1K) model using conventional models. Nevertheless, significantly better fits were obtained using 2 parallel single-tissue compartments, one for parent tracer and the other for labeled metabolites (dual-input model). Robust K1 results were also obtained by fitting the first 5 min of PET data to the 1T1K model, at least when 60-min plasma input data were used. For both models, the test-retest variability of (11)C-laniquidar rate constant for transfer from arterial plasma to tissue (K1) was approximately 19%. CONCLUSION: The accurate quantification of (11)C-laniquidar kinetics in the brain is hampered by its fast metabolism and the likelihood that labeled metabolites enter the brain. Best fits for the entire 60 min of data were obtained using a dual-input model, accounting for uptake of (11)C-laniquidar and its labeled metabolites. Alternatively, K1 could be obtained from a 5-min scan using a standard 1T1K model. In both cases, the test-retest variability of K1 was approximately 19%.

RESUMO

(-)-OSU6162 is a dopamine stabilizer that can counteract both hyperdopaminergic and hypodopaminergic states. In this study, D2/D3 receptor occupancy of (-)-OSU6162 in the human brain was investigated using positron emission tomography (PET). Twelve male healthy volunteers underwent [(11)C]raclopride PET scanning before and 1 h after a single oral dose of (-)-OSU6162 (15-90 mg). Blood samples for determination of (-)-OSU6162 and prolactin plasma levels were collected at Tmax. Parametric images of [(11)C]raclopride binding potential relative to nondisplaceable tissue (cerebellar grey matter) uptake (BPND) at baseline and after (-)-OSU6162 administration were generated using the simplified reference tissue model. MRI-based regions of interest were defined for the striatum, composed of caudate nucleus and putamen, and projected onto the co-registered parametric [(11)C]raclopride BPND image. Furthermore, three striatal subregions, ie, anterior dorsal caudate, anterior dorsal putamen, and ventral striatum, were defined manually and additionally analyzed. Plasma concentrations of (-)-OSU6162, ranging from 0.01 to 0.9 µM, showed a linear relationship with prolactin levels, reflecting blockade of pituitary D2 receptors. A concentration-dependent increase in striatal D2/D3 receptor occupancy was observed, reaching a value of about 20% at an (-)-OSU6162 plasma level of 0.2 µM, and which for higher concentrations leveled off to a maximal occupancy of about 40%. Findings were similar in the striatal subregions. The present data corroborate the notion that (-)-OSU6162 binds preferentially to a subpopulation of D2/D3 receptors, possibly predominantly extrasynaptic, and this may form the basis for the dopamine-stabilizing properties of (-)-OSU6162.

RESUMO

Clumsiness in preschool children may be a precursor to impaired academic performance and psychological and developmental problems. It is assumed that in this age group especially the qualitative aspects (=pattern) of a movement reflect variations in motor development. Currently available motor tests for this age group, however, mostly objectify quantitative aspects of a movement alone and do not objectify qualitative aspects. The aim of this study was to develop a new, valid, and reliable tool (Maastricht's Motor Test (MMT)) to objectify qualitative and quantitative aspects of movement in 5- to 6-year-old children. The test covers Static Balance (14 items), Dynamic Balance (20 items), Ball Skills (eight items), and Diadochokinesis and Manual Dexterity (28 items). About 50% of the items measure qualitative aspects and 50% quantitative aspects of movements. In total 487 subjects were recruited from the first year of primary school. To validate the test, one school doctor's global judgment was used as a form of expert validity. Sensitivity and specificity were calculated for different cut-off points. Intra-class correlation coefficients (ICC) of inter-rater (N = 42), intra-rater (N = 24), and test-retest (N = 43) agreement were determined. ICCs of the qualitative total score ranged from 0.61 to 0.95 and were comparable with those of the total quantitative score. The MMT can be used to objectify both qualitative and quantitative aspects of movements. The additional value of the qualitative observations has to be determined in children with various developmental problems.

RESUMO

OBJECTIVE: To examine the potential of a questionnaire (CQI 'R-ICU') to measure the quality of care from the perspective of relatives in the Intensive Care Unit (ICU). METHODS: A quantitative survey study has been undertaken to explore the psychometric properties of the instrument, which was sent to 282 relatives of ICU patients from the Erasmus MC, an academic hospital in Rotterdam, the Netherlands. Factor-analyses were performed to explore the underlying theoretical structure. RESULTS: Survey data from 211 relatives (response rate 78%) were used for the analysis. The overall reliability of the questionnaire was sufficiently high; two of the four underlying factors, namely 'Communication' and 'Involvement', were significant predictors. Two specific aspects of care that needed the most improvement were missing information about meals and offering an ICU diary. There is a significant difference in mean communication with nurses among the four wards in Erasmus MC. CONCLUSIONS: The CQI 'R-ICU' seems to be a valid, reliable and usable instrument. The theoretical fundament appears to be related to communication.
