Therapeutic communication improves patient comfort during venipuncture in children: a single-blinded intervention study

The aim of this study was to examine whether therapeutic communication improves children's comfort during venipuncture compared to standard communication. This study was registered in the Dutch trial register (NL8221), December 10, 2019. This single-blinded interventional study was carried out in an outpatient clinic of a tertiary hospital. Inclusion criteria were age between 5 and 18 years, use of topical anesthesia (EMLA) and sufficient understanding of the Dutch language. 105 children were included, 51 assigned to the standard communication group (SC group) and 54 patients to the therapeutic communication group (TC group). The primary outcome measure was self-reported pain based on the Faces Pain Scale Revised (FPS-R). Secondary outcome measures were observed pain (numeric rating scale (NRS)), self-reported/observed anxiety in child and parent (NRS), self-reported satisfaction in child, parent and medical personnel (NRS), and procedural time. No difference was found for self-reported pain. Self-reported and observed anxiety (by parents and medical personnel) was lower in the TC group (p-values ranged from p = 0.005 to p = 0.048). Procedural time was lower in the TC group (p = 0.011). Satisfaction level of medical personnel was higher in the TC group (p = 0.014).   Conclusion: TC during venipuncture did not result in lower self-reported pain. However, secondary outcomes (observed pain, anxiety and procedural time) were significantly improved in the TC group. What is Known: • Medical procedures, especially needle related procedures, cause anxiety and fear in children and adults. • In adults communication techniques based on hypnosis are effective in reducing pain and anxiety during medical procedures. What is New: • Our study found that with a small change in communication technique (called therapeutic communication or TC), the comfort of children during venipuncture improves. • This improved comfort was mainly reflected by reduced anxiety scores and shorter procedural time. This makes TC suitable for the outpatient setting.

De novo mutations in children born after medical assisted reproduction

STUDY QUESTION

Are there more de novo mutations (DNMs) present in the genomes of children born through medical assisted reproduction (MAR) compared to spontaneously conceived children?

SUMMARY ANSWER

In this pilot study, no statistically significant difference was observed in the number of DNMs observed in the genomes of MAR children versus spontaneously conceived children.

WHAT IS KNOWN ALREADY

DNMs are known to play a major role in sporadic disorders with reduced fitness such as severe developmental disorders, including intellectual disability and epilepsy. Advanced paternal age is known to place offspring at increased disease risk, amongst others by increasing the number of DNMs in their genome. There are very few studies reporting on the effect of MAR on the number of DNMs in the offspring, especially when male infertility is known to be affecting the potential fathers. With delayed parenthood an ongoing epidemiological trend in the 21st century, there are more children born from fathers of advanced age and more children born through MAR every day.

STUDY DESIGN, SIZE, DURATION

This observational pilot study was conducted from January 2015 to March 2019 in the tertiary care centre at Radboud University Medical Center. We included a total of 53 children and their respective parents, forming 49 trios (mother, father and child) and two quartets (mother, father and two siblings). One group of children was born after spontaneous conception (n = 18); a second group of children born after IVF (n = 17) and a third group of children born after ICSI combined with testicular sperm extraction (ICSI-TESE) (n = 18). In this pilot study, we also subdivided each group by paternal age, resulting in a subgroup of children born to younger fathers (<35 years of age at conception) and older fathers (>45 years of age at conception).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Whole-genome sequencing (WGS) was performed on all parent-offspring trios to identify DNMs. For 34 of 53 trios/quartets, WGS was performed twice to independently detect and validate the presence of DNMs. Quality of WGS-based DNM calling was independently assessed by targeted Sanger sequencing.

MAIN RESULTS AND THE ROLE OF CHANCE

No significant differences were observed in the number of DNMs per child for the different methods of conception, independent of parental age at conception (multi-factorial ANOVA, f(2) = 0.17, P-value = 0.85). As expected, a clear paternal age effect was observed after adjusting for method of conception and maternal age at conception (multiple regression model, t = 5.636, P-value = 8.97 × 10-7), with on average 71 DNMs in the genomes of children born to young fathers (<35 years of age) and an average of 94 DNMs in the genomes of children born to older fathers (>45 years of age).

LIMITATIONS, REASONS FOR CAUTION

This is a pilot study and other small-scale studies have recently reported contrasting results. Larger unbiased studies are required to confirm or falsify these results.

WIDER IMPLICATIONS OF THE FINDINGS

This pilot study did not show an effect for the method of conception on the number of DNMs per genome in offspring. Given the role that DNMs play in disease risk, this negative result is good news for IVF and ICSI-TESE born children, if replicated in a larger cohort.

Common needs in uncommon conditions: a qualitative study to explore the need for care in pediatric patients with rare diseases

Background

Challenges faced by children diagnosed with a rare disease or complex condition and their family members are often characterized by disease-specific complexities, such as a prolonged diagnostic process, an uncertain prognosis, and the absence of curative treatment. The psychological burden of living with a rare disease or complex condition is often understudied and may present overarching concepts that shape the general experience of having been diagnosed with a rare condition. The present study examines common needs from a comprehensive perspective combining relevant aspects from the rare disease literature in a theoretical perspective from pediatric psychology, such as a family-centred, developmental and interdisciplinary approach. An exploratory study was designed among parents from children with a rare disease or complex condition in an Integrated University Children’s Hospital in the Netherlands. Semi-structured interviews were conducted with open-ended questions based around the experience of having a child diagnosed with a rare condition, such as the psychosocial impact on the child and it’s development, the impact on the family, and how provided care was experienced.

Results

Twelve interviews were analysed with a thematic content analysis to identify common needs. Eight themes followed from the analysis and uncovered the need for (1) family-focused care, (2) coping with uncertainty, (3) empathic communication, (4) practical support, (5) information, (6) psychological support, (7) interdisciplinary care, and (8) social support.

Conclusions

The results from our study provide directions for research and health care to support young patients with a rare disease or complex condition and their families. Moreover, our results demonstrated that there are overarching concepts across different rare diseases that may be optimally supported with interdisciplinary care.

Explaining placebo effects in an online survey study: Does 'Pavlov' ring a bell?

OBJECTIVES

Despite the increasing knowledge about placebo effects and their beneficial impact on treatment outcomes, strategies that explicitly employ these mechanisms remain scarce. To benefit from placebo effects, it is important to gain better understanding in how individuals want to be informed about placebo effects (for example about the underlying mechanisms that steer placebo effects). The main aim of this study was to investigate placebo information strategies in a general population sample by assessing current placebo knowledge, preferences for different placebo explanations (built around well-known mechanisms involved in placebo effects), and attitudes and acceptability towards the use of placebo effects in treatment.

DESIGN

Online survey.

SETTING

Leiden, The Netherlands.

PARTICIPANTS

444 participants (377 completers), aged 16-78 years.

MAIN OUTCOME MEASURES

Current placebo knowledge, placebo explanation preferences, and placebo attitudes and acceptability.

RESULTS

Participants scored high on current placebo knowledge (correct answers: M = 81.15%, SD = 12.75). Comparisons of 8 different placebo explanations revealed that participants preferred explanations based on brain mechanisms and positive expectations more than all other explanations (F(7, 368) = 3.618, p = .001). Furthermore, attitudes and acceptability for placebos in treatment varied for the type of the condition (i.e. more acceptant for psychological complaints) and participants indicated that physicians do not always have to be honest while making use of placebo effects for therapeutic benefit.

CONCLUSION

Our results brought forth new evidence in placebo information strategies, and indicated that explanations based on brain mechanisms and positive expectations were most preferred. These results can be insightful to construct placebo information strategies for both clinical context and research practices.

Integrating Placebo Effects in General Practice: A Cross-Sectional Survey to Investigate Perspectives From Health Care Professionals in the Netherlands

Objectives: Placebo effects, beneficial treatment outcomes due to non-active treatment components, play an important role in the overall treatment response. To facilitate these beneficial effects it is important to explore the perspectives of health care professionals (HCPs) on the integration of placebo effects in clinical care. Three themes were investigated: knowledge about placebo effects and factors that contribute to these, frequency of placebo use, and attitudes toward acceptability and transparency of placebo use in treatment. Methods: A cross-sectional survey, according to the Checklist for Reporting Results of Internet E-Surveys guidelines and STrengthening the Reporting of OBservational Studies in Epidemiology (STROBE), was conducted in the Netherlands in 2020. The survey was conducted in two samples: a (nested) short survey in 78 nurses during working shifts (sample 1) and an extended online survey in 47 general HCPs e.g., medical psychologists, oncologists, surgeons (sample 2). Results: Respondents from both samples reported to be somewhat or quite familiar with placebo effects (24.0 and 47.2%, respectively). From the six placebo mechanisms that were presented, mind-body interaction, positive expectations, and brain activity involved in placebo effects were rated as the most influential factors in placebo effects [F_(5,119) = 20.921, p < 0.001]. The use of placebo effects was reported in 53.8% (n = 42) of the nurses (e.g., by inducing positive expectations), and 17.4% of the HCPs (n = 8 reported to make use of pure placebos and 30.4% of impure placebos (n = 14). Attitudes toward placebo use in treatment were acceptant, and transparency was highly valued (both up to 51%). Conclusions: The findings from this study address knowledge gaps in placebo effects in practice and provide insights in attitudes toward the integration of placebo effects from HCPs. Altogether, integrating these findings may potentially optimize treatment outcomes.

Pharmacological conditioning for juvenile idiopathic arthritis: a potential solution to reduce methotrexate intolerance

BACKGROUND

Methotrexate (MTX) therapy has proven to be a successful and safe treatment for Juvenile Idiopathic Arthritis (JIA). Despite the high efficacy rates of MTX, treatment outcomes are often complicated by burdensome gastro-intestinal side effects. Intolerance rates for MTX in children are high (approximately 50%) and thus far no conclusive effective treatment strategies to control for side effects have been found. To address this need, this article proposes an innovative research approach based on pharmacological conditioning, to reduce MTX intolerance.

PRESENTATION OF THE HYPOTHESIS

A collaboration between medical psychologists, pediatric rheumatologists, pharmacologists and patient groups was set up to develop an innovative research design that may be implemented to study potential improved control of side effects in JIA, by making use of the psychobiological principles of pharmacological conditioning. In pharmacological conditioning designs, learned positive associations from drug therapies (conditioning effects) are integrated in regular treatment regimens to maximize treatment outcomes. Medication regimens with immunosuppressant drugs that made use of pharmacological conditioning principles have been shown to lead to optimized therapeutic effects with reduced drug dosing, which might ultimately cause a reduction in side effects.

TESTING THE HYPOTHESIS

This research design is tailored to serve the needs of the JIA patient group. We developed a research design in collaboration with an interdisciplinary research group consisting of patient representatives, pediatric rheumatologists, pharmacologists, and medical psychologists.

IMPLICATIONS OF THE HYPOTHESIS

Based on previous experimental and clinical findings of pharmacological conditioning with immune responses, we propose that the JIA patient group is particularly suited to benefit from a pharmacological conditioning design. Moreover, findings from this study may potentially also be promising for other patient groups that endure long-lasting drug therapies.

PD03-08: BRCA1-Like Triple Negative Tumors: Clinicopathological Variables and Chemosensitivity to Alkylating Agents

Background

Our group has previously employed array Comparative Genomic Hybridization (aCGH) to assess the genomic patterns of BRCA1-mutated breast cancers. It is reasonable to assume that this pattern indicates ‘BRCAness’ and thus serves as a marker for homologous recombination deficiency. This BRCA1-like aCGH profile is also present in about half of all triple negative sporadic breast cancers and has been shown to be predictive for benefit from intensive chemotherapy with DNA crosslinking agents. To study BRCA1-like tumors and conventional dose chemotherapy sensitivity in more detail, we compared clinical factors and survival rates in a uniform cohort of triple negative breast tumors treated with alkylating agents.

Patients and methods

103 patients with triple negative tumors received conventional dose adjuvant chemotherapy with doxorubicin/cyclophosphamide. DNA was extracted from tumor samples and BRCA1-like profiles were assessed. Tumors were classified as BRCA1 -like or non-BRCA1-like. Standard clinical and histopathological factors were determined and compared between both groups. Relapse free survival (RFS), disease specific survival (DSS) and overall survival (OS) after diagnosis were compared between BRCA1-like and non-BRCA1-like tumors.

Results

66 tumors (65%) had a BRCA1-like profile, while 35 tumors (35%) did not show such a profile. Patients with BRCA1-like tumors tended to be younger and had more often node-negative disease compared to the patients with non-BRCA1-like tumors (p=0.058 and p=0.034, respectively). There was no significant difference in survival between BRCA1-like and non BRCA1-like patients after treatment with alkylating agents: the median RFS was 121 vs. 109 months, median DSS was 129 vs. 114 months and OS was 127 vs. 110 months, for BRCA1-like versus non-BRCA1-like tumors. T-stage was the only variable significantly associated with survival.

Conclusion

BRCA1-like tumors occurred in younger patients and were more often node negative, which are features shared with tumors in BRCA1-mutation carriers. We did not observe a difference in survival between BRCA1-like and non-BRCA1-like triple negative breast cancers after treatment with conventional dose chemotherapy with alkylating agents. These results confirm our previous findings that BRCA1-like tumors have similar sensitivity to anthracycline-based adjuvant chemotherapy as other triple-negative tumors. It will be important to establish whether BRCA1-like tumors also share the exquisite sensitivity of BRCA-mutated tumors to PARP-inhibitors.
