The paradoxes of communication and collaboration in maternity care:A video-reflexivity study with professionals and parents
Background: Research on maternity care often focuses on factors that prevent good communication and collaboration and rarely includes important stakeholders – parents – as co-researchers. To understand how professionals and parents in Dutch maternity care accomplish constructive communication and collaboration, we examined their interactions in the clinic, looking for “good practice”. Methods: We used the video-reflexive ethnographic method in 9 midwifery practices and 2 obstetric units. Findings: We conducted 16 meetings where participants reflected on video recordings of their clinical interactions. We found that informal strategies facilitate communication and collaboration: “talk work” – small talk and humour – and “work beyond words” – familiarity, use of sight, touch, sound, and non-verbal gestures. When using these strategies, participants noted that it is important to be sensitive to context, to the values and feelings of others, and to the timing of care. Our analysis of their ways of being sensitive shows that good communication and collaboration involves “paradoxical care”, e.g., concurrent acts of “regulated spontaneity” and “informal formalities”. Discussion: Acknowledging and reinforcing paradoxical care skills will help caregivers develop the competencies needed to address the changing demands of health care. The video-reflexive ethnographic method offers an innovative approach to studying everyday work, focusing on informal and implicit aspects of practice and providing a bottom up approach, integrating researchers, professionals and parents. Conclusion: Good communication and collaboration in maternity care involves “paradoxical care” requiring social sensitivity and self-reflection, skills that should be included as part of professional training
Improved GMP-compliant multi-dose production and quality control of 6-[18F]fluoro-L-DOPA
Background: 6-[18F]Fluoro-L-3,4-dihydroxyphenylalanine (FDOPA) is a frequently used radiopharmaceutical for detecting neuroendocrine and brain tumors and for the differential diagnosis of Parkinson’s disease. To meet the demand for FDOPA, a high-yield GMP-compliant production method is required. Therefore, this study aimed to improve the FDOPA production and quality control procedures to enable distribution of the radiopharmaceutical over distances. FDOPA was prepared by electrophilic fluorination of the trimethylstannyl precursor with [18F]F2, produced from [18O]2 via the double-shoot approach, leading to FDOPA with higher specific activity as compared to FDOPA which was synthesized, using [18F]F2 produced from 20Ne, leading to FDOPA with a lower specific activity. The quality control of the product was performed using a validated UPLC system and compared with quality control with a conventional HPLC system. Impurities were identified using UPLC-MS. Results: The [18O]2 double-shoot radionuclide production method yielded significantly more [18F]F2 with less carrier F2 than the conventional method starting from 20Ne. After adjustment of radiolabeling parameters substantially higher amounts of FDOPA with higher specific activity could be obtained. Quality control by UPLC was much faster and detected more side-products than HPLC. UPLC-MS showed that the most important side-product was FDOPA-quinone, rather than 6-hydroxydopa as suggested by the European Pharmacopoeia. Conclusion: The production and quality control of FDOPA were significantly improved by introducing the [18O]2 double-shoot radionuclide production method, and product analysis by UPLC, respectively. As a result, FDOPA is now routinely available for clinical practice and for distribution over distances
The human norepinephrine transporter in combination with C-11-m-hydroxyephedrine as a reporter gene/reporter probe for PET of gene therapy
Although the herpes simplex virus thymidine kinase gene has been frequently applied as a reporter gene for monitoring gene transfection in animals, it has some intrinsic limitations for use in humans. In our search for a reporter gene that lacks these limitations, we have evaluated the feasibility of the human norepinephrine transporter (hNET) as a reporter gene in combination with the reporter probe C-11-m-hydroxyephedrine (mHED) for PET. Methods: An adenoviral vector (AdTrack-hNET) containing the hNET gene as reporter gene and the enhanced green fluorescent protein (EGFP) as a substitute for a therapeutic gene was constructed. After COS-7, A2780, and U373 cells were transiently transduced with AdTrack-hNET, hNET protein expression, EGFP fluorescence, and cellular uptake of C-11-mHED were determined. In rats, U373 tumor xenografts were grown and transiently transduced with either AdTrack-hNET or an AdTrack-Luc control adenovirus. Intratumoral accumulation of C-11-mHED was determined by PET and ex vivo biodistribution. The tumors were subsequently examined for EGFP fluorescence. Results: 11C-mHED uptake was positively correlated with AdTrack-hNET viral titer and hNET protein expression. However, large differences in transfection efficiency between cell lines were observed. The highest 11C-mHED uptake was found in hNET transfected U373 cells, in which tracer uptake was > 70-fold higher than that in control cells. 11C-mHED accumulation could be inhibited by desipramine, a potent inhibitor of hNET. In all cell lines, C-11-mHED uptake was positively correlated with EGFP fluorescence, implying that imaging of hNET with 11C-mHED would enable monitoring of a coexpressed therapeutic gene. In the animal model, gene transfection efficiencies were very low, as determined by EGFP fluorescence. Still a significantly higher C-11-mHED uptake in hNIET transduced tumors than that in control tumors was demonstrated by ex vivo biodistribution studies. PET with a clinical camera could visualize 1 of 3 hNET transduced tumors, indicating that the transfection efficiency was near the detection limit. Conclusion: These results indicate that monitoring of gene therapy using the hNET/C-11-mHED reporter gene/probe is feasible, but further investigation with regard to the sensitivity of the technique is required

Using Intervention Mapping for Systematic Development of a Midwife-Delivered Intervention for Prevention and Reduction of Maternal Distress during Pregnancy
The authors describe how Intervention Mapping was used to develop a midwife-led intervention to prevent or reduce maternal distress during pregnancy. An extensive needs assessment showed that both pregnant women and midwives needed to be taught to recognise the vulnerability for developing maternal distress during pregnancy and how to identify maternal distress when it occurs. In addition to these mutual learning needs, women needed to learn to disclose their problems, how to handle maternal distress in their daily lives, and the value of seeking help when necessary. Midwives needed to prepare themselves to provide (collaborative) care for maternal distress. Screening and psycho-education were pathways to support self-disclosure, self-management, mobilizing support and treatment of maternal distress. Theory-based methods - such as tailoring, communicative support, individualization, advance organisers, cultural similarity, consciousness raising, elaboration, and cue altering - were built into a web-based tailored program for women. Information processing, intergroup dialogue training, verbal persuasion, providing cues, facilitation of means, and structural organization were the theory-based methods that were built into a training program and a toolbox for the midwife-delivered program. The program was introduced by means of the training given to midwives from 17 midwife-led practices in the Netherlands and proved to be effective. Finally, process and effect evaluations were planned
The influence of preferred place of birth on the course of pregnancy and labor among healthy nulliparous women: a prospective cohort study
__Abstract__
BACKGROUND:
Most studies on birth settings investigate the association between planned place of birth at the start of labor and birth outcomes and intervention rates. To optimize maternity care it also is important to pay attention to the entire process of pregnancy and childbirth. This study explores the association between the initial preferred place of birth and model of care, and the course of pregnancy and labor in low-risk nulliparous women in the Netherlands.
METHODS:
As part of a Dutch prospective cohort study (2007-2011), we compared medical indications during pregnancy and birth outcomes of 576 women who initially preferred a home birth (n = 226), a midwife-led hospital birth (n = 168) or an obstetrician-led hospital birth (n = 182). Data were obtained by a questionnaire before 20 weeks of gestation and by medical records. Analyses were performed according to the initial preferred place of birth.
RESULTS:
Low-risk nulliparous women who preferred a home birth with midwife-led care were less likely to be diagnosed with a medical indication during pregnancy compared to women who preferred a birth with obstetrician-led care (OR 0.41 95% CI 0.25-0.66). Preferring a birth with midwife-led care - both at home and in hospital - was associated with lower odds of induced labor (OR 0.51 95% CI 0.28-0.95 respectively OR 0.42 95% CI 0.21-0.85) and epidural analgesia (OR 0.32 95% CI 0.18-0.56 respectively OR 0.34 95% CI 0.19-0.62) compared to preferring a birth with obstetrician-led care. In addition, women who preferred a home birth were less likely to experience augmentation of labor (OR 0.54 95% CI 0.32-0.93) and narcotic analgesia (OR 0.41 95% CI 0.21-0.79) compared to women who preferred a birth with obstetrician-led care. We observed no significant association between preferred place of birth and mode of birth.
CONCLUSIONS:
Nulliparous women who initially preferred a home birth were less likely to be diagnosed with a medical indication during pregnancy. Women who initially preferred a birth with midwife-led care - both at home and in hospital - experienced lower rates of interventions during labor. Although some differences can be attributed to the model of care, we suggest that characteristics and attitudes of women themselves also play an important role
Sarcopenia/Muscle Mass is not a Prognostic Factor for Short- and Long-Term Outcome After Esophagectomy for Cancer
Background: Recent studies have suggested that sarcopenia is a prognostic risk indicator of postoperative complications and predicts survival in cancer patients. The aim of this study is to investigate whether sarcopenia is associated with postoperative short-term outcome (morbidity and mortality) and long-term survival in patients undergoing esophagectomy for cancer after neoadjuvant chemoradiotherapy. Methods: All patients who underwent neoadjuvant chemoradiotherapy followed by esophagectomy for cancer, and of whom an adequate CT scan was available, were included in the current study. The presence of sarcopenia was defined by CT imaging using cut-off values of the total cross-sectional muscle tissue measured transversely at the third lumbar level. Results: A total number of 120 patients were eligible for analysis. Almost half of the patients (NÂ =Â 54, 45Â %) were classified as having sarcopenia; 24 sarcopenic patients (44Â %) had overweight and 5 sarcopenic patients (9Â %) were obese. Overall morbidity and mortality rate did not differ significantly between sarcopenic and non-sarcopenic patients, nor did long-term overall or disease-free survival. Also sarcopenic obesity was not associated with worse outcome. Conclusion: The presence of sarcopenia was not associated with a negative short- and long-term outcome in this selected group of esophageal cancer patients after neoadjuvant chemoradiotherapy followed by esophagectomy
