RESUMEN

OBJECTIVE: In cancer care, optimal communication between patients and their physicians is, among other things, dependent on physicians' emotion regulation, which might be related to physicians' as well as patients' characteristics. In this study, we investigated physicians' emotion regulation during communication with advanced cancer patients, in relation to physicians' (stress, training, and alexithymia) and patients' (sadness, anxiety, and alexithymia) characteristics. METHODS: In this study, 134 real-life consultations between 24 physicians and their patients were audio-recorded and transcribed. The consultations were coded with the "Defence Mechanisms Rating Scale-Clinician." Physicians completed questionnaires about stress, experience, training, and alexithymia, while patients completed questionnaires about sadness, anxiety, and alexithymia. Data were analysed using linear mixed effect models. RESULTS: Physicians used several defence mechanisms when communicating with their patients. Overall defensive functioning was negatively related to physicians' alexithymia. The number of defence mechanisms used was positively related to physicians' stress and alexithymia as well as to patients' sadness and anxiety. Neither physicians' experience and training nor patients' alexithymia were related to the way physicians regulated their emotions. CONCLUSIONS: This study showed that physicians' emotion regulation is related to both physician (stress and alexithymia) and patient characteristics (sadness and anxiety). The study also generated several hypotheses on how physicians' emotion regulation relates to contextual variables during health care communication in cancer care.

RESUMEN

OBJECTIVE: To investigate which characteristics of the physician and of the consultation are related to patient satisfaction with communication and working alliance. METHODS: Real-life consultations (N = 134) between patients (n = 134) and their physicians (n = 24) were audiotaped. All of the patients were aware of their cancer diagnosis and consulted their physician to discuss the results of tests (CT scans, magnetic resonance imaging, or tumor markers) and the progression of their cancer. The consultations were transcribed and coded with the "Defense Mechanisms Rating Scale-Clinician." The patients and physicians completed questionnaires about stress, satisfaction, and alliance, and the data were analyzed using robust linear modeling. RESULTS: Patient satisfaction with communication and working alliance was high. Both were significantly (negatively) related to the physician's neurotic and action defenses-in particular to the defenses of displacement, self-devaluation, acting out, and hypochondriasis-as well as to the physician's stress level. The content of the consultation was not significantly related to the patient outcomes. CONCLUSIONS: Our study shows that patient satisfaction with communication and working alliance is not influenced by the content of the consultation but is significantly associated with the physician's self-regulation (defense mechanisms) and stress. The results of this study might contribute to optimizing communication skills training and to improving communication and working alliance in cancer care.

RESUMEN

AIM: This randomized, controlled trial examined the medium-term effectiveness of online behavioral training in migraine self-management (oBT; N = 195) versus waitlist control (WLC; N = 173) on attack frequency, indicators of self-management (primary outcomes), headache top intensity, use of rescue medications, quality of life and disability (secondary outcomes). METHODS: An online headache diary following the ICHD-II and questionnaires were completed at baseline (T0), post-training (T1) and six months later (T2). Missing data (T1: 24%; T2: 37%) were handled by multiple imputation. We established effect sizes (ES) and tested between-group differences over time with linear mixed modelling techniques based on the intention-to-treat principle. RESULTS: At T2, attack frequency had improved significantly in oBT (-23%, ES = 0.66) but also in WLC (-19%; ES = 0.52). Self-efficacy, internal and external control in migraine management--and triptan use--improved only in oBT, however. This indicates different processes in both groups and could signify (the start of) active self-management in oBT. Also, only oBT improved migraine-specific quality of life to a sizable extent. CONCLUSIONS: oBT produced self-management gains but could not account for improved attack frequency, because WLC improved as well. The perspective that BT effects develop gradually, and that online delivery will boost BT outreach, justifies further research.

RESUMEN

OBJECTIVE: The aim of this study was to review the literature on clinician characteristics influencing patient-clinician communication or patient outcome in oncology. METHODS: Studies investigating the association of clinician characteristics with quality of communication and with outcome for adult cancer patients were systematically searched in MEDLINE, PSYINFO, PUBMED, EMBASE, CINHAL, Web of Science and The Cochrane Library up to November 2012. We used the preferred reporting items for systematic reviews and meta-analyses statement to guide our review. Articles were extracted independently by two of the authors using predefined criteria. RESULTS: Twenty seven articles met the inclusion criteria. Clinician characteristics included a variety of sociodemographic, relational, and personal characteristics. A positive impact on quality of communication and/or patient outcome was reported for communication skills training, an external locus of control, empathy, a socioemotional approach, shared decision-making style, higher anxiety, and defensiveness. A negative impact was reported for increased level of fatigue and burnout and expression of worry. Professional experience of clinicians was not related to communication and/or to patient outcome, and divergent results were reported for clinician gender, age, stress, posture, and confidence or self-efficacy. CONCLUSIONS: Various clinician characteristics have different effects on quality of communication and/or patient outcome. Research is needed to investigate the pathways leading to effective communication between clinicians and patients.

RESUMEN

Opioid neurotransmission has a key role in mediating reward-related behaviours. Opioid receptor (OR) antagonists, such as naltrexone (NTX), can attenuate the behaviour-reinforcing effects of primary (food) and secondary rewards. GSK1521498 is a novel OR ligand, which behaves as an inverse agonist at the µ-OR sub-type. In a sample of healthy volunteers, we used [(11)C]-carfentanil positron emission tomography to measure the OR occupancy and functional magnetic resonance imaging (fMRI) to measure activation of brain reward centres by palatable food stimuli before and after single oral doses of GSK1521498 (range, 0.4-100 mg) or NTX (range, 2-50 mg). GSK1521498 had high affinity for human brain ORs (GSK1521498 effective concentration 50 = 7.10 ng ml(-1)) and there was a direct relationship between receptor occupancy (RO) and plasma concentrations of GSK1521498. However, for both NTX and its principal active metabolite in humans, 6-ß-NTX, this relationship was indirect. GSK1521498, but not NTX, significantly attenuated the fMRI activation of the amygdala by a palatable food stimulus. We thus have shown how the pharmacological properties of OR antagonists can be characterised directly in humans by a novel integration of molecular and functional neuroimaging techniques. GSK1521498 was differentiated from NTX in terms of its pharmacokinetics, target affinity, plasma concentration-RO relationships and pharmacodynamic effects on food reward processing in the brain. Pharmacological differentiation of these molecules suggests that they may have different therapeutic profiles for treatment of overeating and other disorders of compulsive consumption.

RESUMEN

BACKGROUND: The characteristics of polycystic ovary syndrome (PCOS) such as hyperandrogenism and anovulation can be highly stressful and might negatively affect psychological well-being and sexuality. The objective of this study was to evaluate the association between PCOS characteristics and psychological well-being as well as sexarche. METHODS: Patients (n = 1148) underwent standardized clinical evaluation. Psychological well-being was investigated in 480 patients with the Rosenberg self-esteem scale (RSES), the body cathexis scale (BCS) and the fear of negative appearance evaluation scale (FNAES). Sexarche was also assessed. RESULTS: Amenorrhoea was associated with lower self-esteem (P = 0.03), greater fear of negative appearance evaluation (P = 0.01) and earlier sexarche (P= 0.004). Hyperandrogenism and acne were associated with poorer body satisfaction (P = 0.03, 0.02, respectively). Hirsutism and BMI were negatively associated with all psychological variables (RSES, P = 0.01; BCS, P = 0.05; FNAES, P = 0.02 and RSES, P = 0.03; BCS, P = 0.001; FNAES, P = 0.03, respectively). CONCLUSIONS: Our results suggest that menstrual irregularities might be related to sexarche. Moreover, this study stresses that the treatment of women with PCOS should notably focus on physical but also on psychological and sexual characteristics.

RESUMEN

The type-1 glycine transporter (GlyT1) is an important target for the development of new medications for schizophrenia. A specific and selective positron emission tomography (PET) GlyT1 ligand would facilitate drug development studies to determine whether a drug reaches this target and help establish suitable doses for clinical trials. This article describes the evaluation of three candidate GlyT1 PET radioligands (GSK931145, GSK565710, and GSK991022) selected from a library of compounds based on favorable physicochemical and pharmacological properties. Each candidate was successfully labeled using [(11)C]methyl iodide or [(11)C]methyl triflate and administered to a pig pre- and postadministration with a pharmacological dose of a GlyT1 inhibitor to determine their suitability as PET ligands in the porcine brain in vivo. All three candidate ligands were analyzed quantitatively with compartment analyses employing a plasma input function. [(11)C]GSK931145 showed good brain penetration and a heterogeneous distribution in agreement with reported GlyT1 localization. Following pretreatment with GSK565710, uptake of [(11)C]GSK931145 was reduced to homogeneous levels. Although [(11)C]GSK565710 also showed good brain penetration and a heterogeneous distribution, the apparent level of specific binding was reduced compared to [(11)C]GSK931145. In contrast, [(11)C]GSK991022 showed a much lower brain penetration and resultant signal following pretreatment with GSK565710. Based on these findings [(11)C]GSK931145 was identified as the most promising ligand for imaging GlyT1 in the porcine brain, possessing good brain penetration, specific signal, and reversible kinetics. [(11)C]GSK931145 is now being progressed into higher species.

RESUMEN

Knowledge on the quality of life of children with headache is lacking. Until now only a few studies in this field have provided information on a limited number of life domains. The aim of this study was to assess the quality of life in a comprehensive number of life domains in children with primary headache presenting at an out-patient paediatric department in a general hospital. From October 2003 to October 2005 all children referred to the out-patient paediatric department of the Vlietland Hospital because of primary headache were investigated by protocol. A thorough history was taken and a general physical and neurological examination was performed. The International Headache Society criteria were used for classification. Quality of life (QoL) was measured using the Dutch version of the Child Health Questionnaire (CHQ-PF50 Dutch edition) and compared with data from a previously investigated cohort of healthy children from the same region, and with data from a cohort of children from the USA with asthma or with attention deficit hyperactivity disorder (ADHD), investigated with the CHQ-PF50. A total of 70 primary headache patients were included in the study (25 with tension-type headache, 36 with migraine, seven with chronic tension-type headache, two with both tension-type headache and migraine). Their mean age was 10.6 years (range 4-17 years); 37 children were male. On all but one subscale (self-esteem) the QoL of the children with primary headache was decreased compared with the cohort of healthy children, especially on the domains of mental health, parental impact time and family cohesion. Compared with the cohort of children with asthma the QoL was significantly worse for our headache group on seven subscales and significantly better on one subscale (general health perception). Compared with the cohort of children with ADHD, the QoL was significantly worse on six subscales but significantly better on three subscales. There were no significant differences on any QoL subscale between children with tension-type headache and children with migraine. We conclude that the QoL in children with primary headache presenting at the out-patient paediatric department of a general hospital seems to be considerably diminished. Furthermore, we conclude that, in this population there is no difference in QoL between children with tension-type headache and those with migraine.

RESUMEN

In a large retail business group the ID Migraine Screening Test was sent to employees with three or more absences from work in the past year (n = 2893). Employees with positive results were invited for a neurological consultation and migraine patients were randomly assigned to: first attack 'treated as usual' and the second attack treated with 40 mg eletriptan, or reversed order. Of the 2893 employees, 799 responded (28%), 260 were positively screened for migraine (33%), 84 patients were diagnosed by a neurologist and 41 of the 75 included patients completed the protocol. Eletriptan induced pain-free response in 33.3% of the patients at 4 h compared with 0% after 'non-specific' treatment (P = 0.03). Eletriptan also significantly improved quality of life, but differences in absence from work and productivity loss could not be detected. In conclusion, in-company screening can be beneficial for undertreated employees, but implementation obstacles can reduce the effectiveness of screening.

RESUMEN

OBJECTIVES: The Distress Thermometer (DT) is a promising instrument to get insight into distress experienced by cancer patients. At our Family Cancer Clinic the DT, including an adapted problem list, was completed by 100 women at increased risk of developing hereditary breast cancer (mean age 45.2 years; SD: 10.5). Additionally, the women filled in either the Hospital Anxiety and Depression Scale as psychological component (n=48) or the somatic subscale of the Symptom Checklist-90 as somatic component (n=50) to identify associations with the DT-score. Further, the women filled in an evaluation form. RESULTS: The median score on the DT was 2 (range: 0-9). With regression analysis adjusted for age, the contribution of mood and somatic complaints, respectively, was investigated. The standardized regression coefficient for anxiety was 0.32 (ns), for depression 0.14 (ns) and for the somatic subscale 0.49 (p<0.001). The explained variance for anxiety and depression was 16%, and for somatic complaints 24%. The differences between the coefficients were not significant. Evaluation forms were returned by 73 women. In 50% of the cases, the physician had discussed the DT/problem list, which was appreciated by the majority of these women (80%). Sixty-two percent of the women would recommend the use of the DT for other patients. CONCLUSION: The use of the DT/problem list seems promising for the current population, and was appreciated by the majority of the women. As mood and somatic complaints did not differ significantly in explaining the experienced distress, other candidate factors need to be examined.

RESUMEN

BACKGROUND: Psychological variables, such as anxiety and depression, may have a negative impact on IVF outcomes, but the evidence remains inconclusive. Previous studies have usually measured a single psychological parameter with clinical pregnancy as the outcome. The objective of the current study was to determine whether pretreatment or procedural psychological variables in women undergoing a first IVF cycle affect the chance of achieving a live birth from that cycle. METHODS: Between February 2002 and February 2004, 391 women with an indication for IVF were recruited at two University Medical Centres in The Netherlands. Pretreatment anxiety and depression were measured with the Hospital Anxiety and Depression Scale. The Daily Record Keeping Chart was used to measure negative and positive affect before treatment and daily during ovarian stimulation. Multiple stepwise forward logistic regression analysis was performed with term live birth as the dependent variable. RESULTS: Regression analysis showed that women who expressed less negative affect at baseline were less likely to achieve live birth (P = 0.03). After one IVF cycle, women who received a standard IVF strategy were more likely to reach live birth delivery than those who received a mild IVF strategy (P = 0.002). A male/female indication for IVF was associated with a higher chance of achieving term live birth than a female only indication (P = 0.03). Age, duration of infertility or type of infertility were not independent predictors of live birth. CONCLUSIONS: The relationship between psychological parameters and IVF success rates is more complex than commonly believed. The expression of negative emotions before starting IVF might not be always detrimental for outcomes.

RESUMEN

In conformity with current views on patient empowerment, we designed and evaluated the effects of home-based behavioural training (BT) provided by lay trainers with migraine to small groups of fellow patients. The primary aims of BT were to reduce attack frequency and increase perceived control over and self-confidence in attack prevention. In a randomized controlled trial the BT group (n = 51) was compared with a waitlist-control group (WLC), receiving usual care (n = 57). BT produced a minor (-21%) short-term effect on attack frequency and clinically significant improvement in 35% of the participants. Covariance analysis showed a non-significant trend (P = 0.07) compared with WLC. However, patients' perceived control over migraine attacks and self-confidence in attack prevention increased significantly with large effect sizes. Patients with high baseline attack frequency might benefit more from BT than those with low attack frequency. In conclusion, lay trainers with migraine strengthened fellow patients' perceived control, but did not induce a significant immediate improvement in attack frequency.

RESUMEN

The penetration of drugs into the central nervous system is a composite of both the rate of drug uptake across the blood-brain barrier and the extent of distribution into brain tissue compartments. Clinically, positron emission tomography (PET) is the primary technique for deriving information on drug biodistribution as well as target receptor occupancy. In contrast, rodent models have formed the basis for much of the current understanding of brain penetration within pharmaceutical Drug Discovery. Linking these two areas more effectively would greatly improve the translation of candidate compounds into therapeutic agents. This paper examines two of the major influences on the extent of brain penetration across species, namely plasma protein binding and brain tissue binding. An excellent correlation was noted between unbound brain fractions across species (R(2) > 0.9 rat, pig, and human, n = 21), which is indicative of the high degree of conservation of the central nervous system environment. In vitro estimates of human brain-blood or brain-plasma ratios of marketed central nervous system drugs and PET tracers agree well with in vivo values derived from clinical PET and post-mortem studies. These results suggest that passive diffusion across the blood-brain barrier is an important process for many drugs in humans and highlights the possibility for improved prediction of brain penetration across species.

RESUMEN

OBJECTIVE: To compare a so-called mild in-vitro fertilisation (IVF) treatment strategy with the standard IVF treatment on the following aspects: the chance of a pregnancy resulting in full-term live birth within 1 year, patient discomfort, multiple pregnancies, and costs. DESIGN: Randomised, open-label, prospective trial (www.controlledtrials.com, number ISRCTN35766970). METHOD: 404 patients were assigned to undergo either a mild treatment, consisting of ovarian stimulation with a gonadotrophin releasing hormone (GnRH) antagonist combined with single embryo transfer, or the standard treatment consisting of prolonged stimulation with a GnRH agonist combined with the transfer of two embryos. The primary outcome measures were: (1) the percentage of cumulative pregnancies within one year after randomisation leading to full-term live birth; (2) total costs per couple and child up to 6 weeks after expected delivery; and (3) overall patient discomfort. Analysis was done according to the intention-to-treat principle and was intended to show that the mild treatment was not inferior to the standard treatment; the non-inferiority threshold was -12.5%. RESULTS: The proportion of cumulative pregnancies resulting in full-term live birth after 1 year was 43.4% in the mild and 44.7% in the standard treatment group. The lower limit of the one-sided 95% confidence interval was equal to -9.8%. The respective proportion of couples with multiple pregnancies was 0.5% versus 13.1% (p < 0.0001), and the average total costs were Euro 8,333.- versus Euro 10,745.- (difference: Euro 2,412.-, 95% CI: 703-4,131). There were no statistically significant differences between the groups with regard to anxiety, depression, physical discomfort, and sleep quality. CONCLUSION: After 1 year of treatment, the cumulative percentage of pregnancies leading to full-term live birth and the total patient discomfort were the same for the mild treatment (average 2.3 IVF-cycles) and the standard treatment (average 1.7 IVF-cycles). The mild treatment significantly reduced the number of multiple pregnancies and the overall costs.

RESUMEN

PURPOSE: This implementation study evaluated orthoptists' use of an educational cartoon ("the Patchbook") and other measures to improve compliance with occlusion therapy for amblyopia. METHODS: Participating orthoptists provided standard orthoptic care for one year, adding the Patchbook in the second year. They attended courses on compliance and intercultural communication by communication skills training. Many other compliance-enhancing measures were initiated. Orthoptists' awareness, attitude, and activities regarding noncompliance were assessed through interviews, questionnaires, and observations. Their use of the Patchbook was measured. The study was performed in low socio-economic status (SES) areas and in other areas in the Netherlands. It was attempted to integrate education on compliance into basic and continuing orthoptic training. RESULTS: The Patchbook was used by all 9 orthoptists who participated in low-SES areas and 17 of 23 orthoptists in other areas. Courses changed awareness and attitude about compliance, but this was not sustained. Although orthoptists estimated compliance during patching at 70%, three-quarters never suspected noncompliance during a full day of observation in any of their patients. Explanations to parents who spoke Dutch poorly were short. In the second year, explanations to children were longer. Implementation of all 7 additional compliance-enhancing measures failed. Education on compliance was not integrated into orthoptists' training. CONCLUSION: Almost all orthoptists used the Patchbook and, as another study demonstrated, it proved to be very effective, especially in low-SES areas. Duration of explanation was inversely proportional to parents' fluency in Dutch. Noncompliance was rarely suspected by orthoptists. Although 7 additional compliance-enhancing measures had been conceived and planned with the best intentions, they were not realized. These required extra, unpaid time from the orthoptists, which is especially scarce in hospitals in low-SES areas where the educational cartoon is most needed.

RESUMEN

A two-step radiolabelling protocol of a cancer relevant cRGD peptide is described where the fluorinase enzyme is used to catalyse a transhalogenation reaction to generate [(18)F]-5'-fluoro-5'-deoxy-2-ethynyladenosine, [(18)F]FDEA, followed by a 'click' reaction to an azide tethered cRGD peptide. This protocol offers efficient radiolabelling of a biologically relevant peptide construct in water at pH 7.8, 37 °C in 2 hours, which was metabolically stable in rats and retained high affinity for αVß3 integrin.

RESUMEN

Migraine is a chronic disabling disorder, with migraine episodes significantly reducing quality of life and leading to impaired functioning (physically, socially, emotionally) both at home and at work. We explored whether ambulatory accelerometry can be used as an objective method to quantify the behavioral aspects of migraine-related disability. Four body mounted uni-axial piezo-resistive accelerometers were used to quantify the time spent in different body postures (lying, sitting, standing), physical activities (walking, cycling) and a general index of body motility during eight migraine attacks and subsequent recovery periods of six patients in their habitual environment. The migraine attacks and recovery periods could be monitored after about 1 h, which was the time required for the investigator to travel to the patient and for the sensors to be attached. In order to quantify the influence of a migraine episode on daily activities, we also performed measurements during a headache-free baseline period of the same patients. Overall, the procedures functioned well, indicating that ambulatory accelerometry measurements before, during and after a migraine attack are feasible to perform. Furthermore, our quantitative data revealed that migraine always influenced behavior by reducing overall body motility and that, dependent upon the severity of the attack, the effectiveness of acute treatment and the time of day, the time spent in various body positions, dynamic activities, and the number of postural transitions were affected. This feasibility study showed that ambulatory accelerometry can provide the objective behavioral effect parameters for the evaluation of migraine and its treatment on daily functioning in the habitual environment of migraine patients.

RESUMEN

The aim of this study was to test the reliability and validity of the COMFORT scale as a postoperative pain instrument for children aged 0-3 years. Subjects were 158 neonates and toddlers after major abdominal or thoracic surgery. Trained nurses rated the children's pain at 3, 6 and 9 h postoperative on the Pediatric Surgical Intensive Care Unit using the COMFORT and a VAS for pain. Interrater reliability of the COMFORT items proved to be good (Kappa 0.63-0.93) for all items with the exception of the item 'Respiratory response', which was moderate (Kappa 0.54). LISREL analyses showed that the structure of the COMFORT data was best represented by three latent variables: COMFORT 'behaviour' with loadings from the behavioural items (Alertness, Calmness, Respiratory response/Crying, Physical movement, Muscle tone and Facial tension) and separate latent variables for 'Heart rate baseline' (HR) and 'Mean arterial blood pressure baseline' (MAP). Factor loadings of the items were invariant across time, indicating stability of the structure. The latent variables COMFORT 'behaviour' and VAS pain were highly interrelated indicating congruent validity. Stability of COMFORT 'behaviour' and VAS pain was moderate which might be due to varying painful episodes in this sample. HR and MAP, although stable across time, were weakly related to VAS pain and COMFORT 'behaviour'. These findings support the use of the COMFORT 'behaviour' scale to assess postoperative pain in neonates and infants.

RESUMEN

Previous research has indicated that postoperative distress is influenced by diverse biographic, medical and psychological variables, such as personality, coping behaviours and anxiety. The influence of state variables, apart from anxiety and coping behaviour, has received scant attention. Furthermore, the influence of coping behaviour has remained unclear. The present study investigated coping behaviour and indications of physical distress, i.e., preoperative fatigue, leg pain and back pain, besides preoperative anxiety, as predictors of postoperative anxiety and physical complaints in 126 patients undergoing lumbar surgery. Preoperative anxiety and leg pain independently predicted more postoperative anxiety beyond the influence of age, sex and medical variables. Preoperative anxiety and fatigue independently predicted more postoperative physical complaints. No associations were found between the coping behaviours and the postoperative variables. The implications of these results are discussed in relation to intervention strategies aimed at diminishing the stress of surgery.
