Atomic-scale imaging of a 27-nuclear-spin cluster using a quantum sensor.

Nuclear magnetic resonance (NMR) is a powerful method for determining the structure of molecules and proteins1. Whereas conventional NMR requires averaging over large ensembles, recent progress with single-spin quantum sensors2-9 has created the prospect of magnetic imaging of individual molecules10-13. As an initial step towards this goal, isolated nuclear spins and spin pairs have been mapped14-21. However, large clusters of interacting spins-such as those found in molecules-result in highly complex spectra. Imaging these complex systems is challenging because it requires high spectral resolution and efficient spatial reconstruction with sub-ångström precision. Here we realize such atomic-scale imaging using a single nitrogen vacancy centre as a quantum sensor, and demonstrate it on a model system of 27 coupled 13C nuclear spins in diamond. We present a multidimensional spectroscopy method that isolates individual nuclear-nuclear spin interactions with high spectral resolution (less than 80 millihertz) and high accuracy (2 millihertz). We show that these interactions encode the composition and inter-connectivity of the cluster, and develop methods to extract the three-dimensional structure of the cluster with sub-ångström resolution. Our results demonstrate a key capability towards magnetic imaging of individual molecules and other complex spin systems9-13.

Effectiveness of a Stigma Awareness Intervention on Reemployment of People with Mental Health Issues/Mental Illness: A Cluster Randomised Controlled Trial.

PURPOSE: A barrier for reemployment of people with mental health issues/mental illness (MHI) is workplace stigma and discrimination. In this RCT the effectiveness of a stigma-awareness intervention addressing finding work, retaining work and decisional stress were evaluated. METHODS: A cluster RCT was conducted in 8 Dutch municipal practices. Randomisation took place at practice level. Participants were unemployed people with MHI, receiving social benefits. The intervention consisted of a decision aid for workplace disclosure for participants and a 2 × 3 h stigma-awareness training for their employment specialists. Primary outcomes were measured at baseline, 3-, 6- and 12-months. Multilevel analyses, containing random intercepts of participants nested in organizations, were conducted to analyse the effects of the intervention. RESULTS: Participants (N = 153) were randomized to an experimental (n = 76) or control group (n = 77). At six months, significantly more participants of the experimental group (51%) had found work compared to the control group (26%). At twelve months, significantly more participants of the experimental group (49%) had retained work compared to the control group (23%). Intention-to-treat analyses showed that randomization to the experimental group was associated with finding (OR(95%CI) = 7.78(1.33-45.53), p = 0.02) and retaining (OR(95%CI) = 12.15(2.81-52.63), p < 0.01) work more often at twelve months. Analyses showed that the experimental and control group did not differ in decisional stress. CONCLUSIONS: Our stigma awareness intervention was effective for finding and retaining work. As the percentage of people who found and retained work almost doubled, this suggests that on a societal level, a vast number of unemployed people could be reemployed with a relatively simple intervention. TRIAL REGISTRATION: The study was retrospectively registered at the Dutch Trial Register (TRN: NL7798, date: 04-06-2019).

Oral health assessment in institutionalized elderly: a scoping review.

When elderly become frail and in need for complex care, they can no longer live independently at home and may be admitted to nursing homes. Various studies have shown that oral health in this population is remarkably poor, which may lead to distressing situations and impacts quality of life. A variety of definitions or descriptions for oral health is used. Without a uniform parameter, it is impossible to determine whether oral health in institutionalized elderly is actually improving or deteriorating over time, as well as the effect of (preventive) interventions. In search for an adequate and clinically applicable parameter to determine oral health in this specific patient group, this scoping review aims to give an overview of the currently used parameters for determining oral health in institutionalized elderly. Ninety different parameters were identified, and 50 parameters were solely used by one study. Only 4 parameters were frequently used (in > 20 studies). The relevance of these parameters for this specific patient group is discussed. To aid the planning and commissioning of future research and patient care, there is an urgent need for an adequate and uniform parameter for oral health determination in institutionalized elderly.

Maximizing agricultural reuse of recycled nutrients: A spatially explicit assessment of environmental consequences and costs.

Recovering nutrients from organic materials to reduce artificial fertilizer inputs requires the implementation of processing technologies and can involve considerable logistics and transportation costs. Reducing such costs by directly applying organic materials to agricultural land can contribute to pollution due to potential contaminants and unbalanced nutrient ratios. Assessing the cost of increased recycling requires a spatially explicit approach because availability of organic materials, nutrient demand and agro-ecosystem properties vary spatially. A multi-objective model was developed to estimate the trade-offs between costs of nutrient recovery and improvements in nutrient distribution for a case study area in The Netherlands. The evaluated recovery processes included solid-liquid separation followed by reverse osmosis to recover nutrients from pig manure which was compared to a conventional process via hygienisation and export. Results indicate that, even in a nutrient saturated area, replacement potential of artificial nitrogen (N) and phosphorus (P) fertilizers through locally reclaimed nutrients is limited to about 17% N and 55% P. A cost optimum was found when about 48% of the initial pig manure quantities were processed via nutrient recovery and directed to land. Increasing manure processing for nutrient recovery led to a redistribution of nutrients and trace metals (zinc (Zn) and copper (Cu)), resulting in more localized concentration. Zn and Cu were enriched by about 8% and 2%, respectively, when maximizing nutrient recovery. Our generic model offers a methodology to assess the trade-offs between increased recycling and associated spatial effects to facilitate sustainable recycling infrastructures for achieving more circular agriculture.

[Whether or not to remove root remnants in frail older adults?] / Wel of niet wortelresten verwijderen bij kwetsbare ouderen?

Many frail older adults have a poor oral health: unrestorable broken teeth and root remnants with open root canals, commonly associated with periapical and periodontal inflammation, are often seen. Improving oral health in this growing group of frail older adults is a considerable challenge for dental care professionals. Dentists are often uncertain how to deal with root remnants and unrestorable broken teeth in psychogeriatric and/or medically compromised frail older adults. Decisions about the extraction or retention of root remnants should not only be made on the basis of preventing pain and inflammation, but also on the course of disease, life expectancy, cooperation, laws and regulations and other factors that are an issue in geriatric patients but not in regular (healthy) patients. To help oral health care professionals in their treatment choice for this complex patient group, a decision tree was developed in which both root and patient-related factors were included.

Psychometric properties of the Internalized Stigma of Mental Illness (ISMI-10) scale in a Dutch sample of employees with mental illness.

BACKGROUND: Internalized stigma can have numerous negative effects on the well-being and employment of people with mental illness. Brief, valid, and reliable measures are needed to get a better understanding of self-stigmatization. The aim of this study is to translate the brief version of the Internalized Stigma of Mental Illness (ISMI-10) scale into a Dutch version and to assess the reliability and validity of this Dutch version in a sample of employees with mental illness. METHODS: The ISMI-10 was translated into Dutch using the forward-backward translation procedure. The sample consisted of 161 employees with mental illness. Internal consistency was evaluated and the retest reliability was tested with 68 respondents. The construct validity was evaluated by testing convergent and divergent validity. RESULTS: The Dutch ISMI-10 showed good internal consistency (α = 0.83) and good test-retest reliability (r = 0.73). The Dutch ISMI-10 demonstrated excellent convergent validity; high correlations were found between the Dutch ISMI-10 and hope (r = -0.54), anxiety and depression (r = 0.59), self-esteem (r = -0.56), and empowerment (r = - 0.59). Acceptable divergent validity was indicated; small correlations were found between the Dutch ISMI-10 and the physical functioning subscale (r = -0.27) and the role limitation due to physical problems subscale (r = -0.21), and medium correlations were found between the Dutch ISMI-10 and the general health subscale (r = -0.36). CONCLUSION: The Dutch ISMI-10 demonstrated adequate psychometric properties for assessing internalized stigma and can be used by researchers in Dutch speaking countries to get a better understanding of self-stigmatization among people with mental illness.

In What Ways Does Health Related Stigma Affect Sustainable Employment and Well-Being at Work? A Systematic Review.

PURPOSE: Studies are increasingly showing that health related stigma is a barrier to employment, but it is not known how. The aim of this systematic review is to identify, appraise and analyse studies that have directly or indirectly addressed ways in which stigma affects sustainable employment and well-being at work of people with disabilities. METHODS: Using a multiphase screening process, this review is based on a comprehensive literature search (2000-2019) carried out in six electronic databases: Embase, Web of Science, Medline Ovid, Cochrane CENTRAL, PsycINFO and Google Scholar. RESULTS: 7.263 publications were identified; 96 studies were found eligible to be included in the review. 72% of the studies were conducted in North America or Europe. Few studies directly assessed how stigma affects the employment of people with disabilities. Most studies highlighted that attitudes and behaviour of employers formed a barrier to employment, as well as anticipated stigma and self-stigma in people with health problems. However, the findings also showed that the attitudes and behaviour of co-workers, health care professionals, reintegration professionals, customers, and family and friends could act as a barrier to employment although these influences are under-researched. Although many similarities were seen in the relevant findings of studies about both physical and mental disabilities, several nuances were found. CONCLUSION: Stigma hampers sustainable employment and well-being in multiple ways. Whereas the number of publications on this topic is rapidly increasing, the roles of health care professionals, reintegration professionals, co-workers, customers, and family and friends particularly warrant more attention.

Expectations of Mental Illness Disclosure Outcomes in the Work Context: A Cross-Sectional Study Among Dutch Workers.

Purpose The decision whether to disclose mental illness at work can have important positive and negative consequences for sustainable employment and well-being. The aim of the study is (1) to examine workers' expectations of outcomes of mental illness disclosure in the workplace and to evaluate their expectations regarding which factors are of influence on these outcomes, (2) to identify distinct subgroups of workers, and (3) to characterize these subgroups in terms of personal, sociodemographic, and work-related characteristics. Methods In this cross-sectional survey study, a sample of 1224 Dutch workers was used. Latent Class Analysis (LCA) was used to identify classes of workers based on expected workplace mental illness outcomes. A three-step approach LCA was chosen to investigate whether the classes differed in characteristics. Results The majority of workers expected predominantly positive outcomes of workplace mental illness disclosure (e.g., being able to be one's authentic self; 82.4%), even though they simultaneously expected disclosure to lead to advancement-related discrimination (e.g., lower chances of contract renewal; or getting a promotion; 68.4% and 57%, respectively). Six distinct subgroups of workers were identified based on expected workplace mental illness disclosure outcomes: two positive classes (50.1%), two negative classes (33.3%), and two classes who indicated not to know what the outcomes would be (16.7%). Significant differences between the classes were found on personal experience, work-related association with mental illness, gender, educational level, and workplace atmosphere. Conclusion The disclosure process is complex, as most workers were optimistic (i.e., expected generally positive outcomes) whilst simultaneously expecting workplace discrimination. Subgroup differences in expectations regarding workplace mental illness disclosure outcomes were found.

[General health, healthcare costs and dental care use of elderly with differing oral status]. / Algemene gezondheid, zorgkosten en tandartsbezoek van ouderen met verschillende orale status.

Cross-sectional studies have shown that elderly with a natural dentition or implant-retained overdenture have better general health outcomes than elderly with conventional dentures. It is not known whether these findings would be confirmed in longitudinal studies of such groups of elderly. Therefore, in this study a large group of elderly (aged 75 and over) with a natural dentition (n = 143,199), an implant-retained overdenture (n = 6,503) or conventional denture (n=18,420) were followed over a period of 8 years. Elderly with conventional dentures had chronic conditions more often, used more medication and had higher healthcare costs. Remarkably, the general health outcomes of elderly with an implant-retained overdenture declined over the period of 8 years. At the time the implant-retained overdenture was placed, their general health profile seemed comparable to that of elderly with a natural dentition, but as time progressed it declined to the level of elderly with conventional dentures.

The value of 18F-FDG PET/CT for the diagnosis of device-related infections in patients with a left ventricular assist device: a systematic review and meta-analysis.

BACKGROUND: Left ventricular assist devices (LVADs) are increasingly used for the treatment of advanced heart failure. LVADs improve quality of life and decrease mortality, but the driveline carries substantial risk for major infections. These device-related LVAD and driveline infections are difficult to diagnose with conventional imaging. We reviewed and analysed the current literature on the additive value of 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) imaging for the diagnosis of LVAD-related infections." MATERIALS/METHODS: We performed a systematic literature review using several databases from their inception until the 31st of December, 2019. Studies investigating the diagnostic performance of FDG-PET/CT in patients with suspected LVAD infection were retrieved. After a bias risk assessment using QUADAS-2, a study-aggregate meta-analysis was performed on a per examination-based analysis. RESULTS: A total of 10 studies were included in the systematic review, eight of which were also eligible for study-aggregate meta-analysis. For the meta-analysis, a total of 256 FDG-PET/CT scans, examining pump/pocket and/or driveline infection, were acquired in 230 patients. Pooled sensitivity of FDG-PET/CT was 0.95 (95% confidence interval (CI) 0.89-0.97) and pooled specificity was 0.91 (95% CI 0.54-0.99) for the diagnosis of device-related infection. For pump/pocket infection, sensitivity and specificity of FDG-PET/CT were 0.97 (95%CI 0.69-1.00) and 0.93 (95%CI 0.64-0.99), respectively. For driveline infection, sensitivity and specificity were 0.96 (95%CI 0.88-0.99) and 0.99 (95%CI 0.13-1.00) respectively. Significant heterogeneity existed across studies for specificity, mostly caused by differences in scan procedures. Predefined criteria for suspicion of LVAD and/or driveline infection were lacking in all included studies. CONCLUSIONS: FDG-PET/CT is a valuable tool for assessment of device-related infection in LVAD patients, with high sensitivity and high, albeit variable, specificity. Standardization of FDG-PET/CT procedures and criteria for suspected device-related LVAD infections are needed for consistent reporting of FDG-PET/CT scans.

Perspectives on follow-up care and research for childhood cancer survivors: results from an international SIOP meet-the-expert questionnaire in Kyoto, 2018.

INTRODUCTION: Survival of childhood cancer has increased over the past decades. This has led to the development of strategies aiming to enhance follow-up care and research, for which priorities may vary globally. We explored perspectives of an international healthcare workers panel. METHODS: Attendants of a meet-the-expert session on childhood cancer survivorship at the 2018 SIOP conference completed a survey about their view on important follow-up care and research aspects for survivors below and over 18 years. We analysed overarching categories and subtopics, and compared Asian versus European and North American healthcare workers. RESULTS: A total of 58 participants from different medical specialties (67.2% paediatric oncologists) and continents (48.3% Asia, 39.7% Europe/North America) responded. Follow-up care priorities for survivors below and over 18 years included physical care (39.3% ≤18 years, 35.9% >18 years) and healthcare structure (29.4%, 26.0%). Physical care was also the most important research aspect for both age groups (52.5%, 50.7%). Psychological support was the most frequently reported subtopic. Asian clinicians (n = 22) primarily prioritized physical care aspects of follow-up care, whereas European/North American (n = 19) clinicians underscored the importance of healthcare structure. CONCLUSION: Physical care is the most important aspect of survivorship care and research according to clinicians from several continents. Asian and European/North American respondents shared most priorities, however, healthcare structure was a more important category for European/North American clinicians. The most common subtopic was psychological support, underlining also the need to involve psychologists in follow-up.

[General health of patients receiving an implant-retained overdenture. A cross-sectional study]. / Gezondheidsaspecten van patiënten die een overkappingsprothese op implantaten ontvangen: een cross-sectioneel onderzoek.

Although ample research has been done on implant-retained overdentures, little is known about the age, health aspects and socio-economic status of patients receiving an implant-retained overdenture for the first time. Therefore, a big data study was set up, in cooperation with Vektis (a Dutch national database for all insured and claimed healthcare), with the aim of investigating the aspects mentioned earlier in patients who received implant-retained overdentures between 2009 and 2016. The study showed that these overdentures were predominantly made for the lower jaw, using a bar attachment system. It also showed they were mainly used for relatively young (55- to 75-year-olds) and healthy patients. It was concluded that relatively few implants are placed to support implant-retained overdentures in patients over 85 years of age and in those with diabetes mellitus, although neither are contraindicated.

The experiences of Dutch fathers on fathering children with disabilities: 'Hey, that is a father and his daughter, that is it'.

BACKGROUND: Due to a predominant focus on mothers, fathers of children with disabilities are greatly overlooked in research. One could argue that there is a lack of research on the multifaceted nature of fatherhood altogether. Therefore, this study aims to gain insight into the perceived experiences of fathers of children with disabilities. METHODS: These perceptions were studied by analysing data generated through semi-structured interviews, which were conducted with 12 Dutch fathers of children or young adults with disabilities. RESULTS: Categories found during our data analysis were similar to those illustrated in the 'conceptual framework on responsible fathering' by including role identification, commitment, employment characteristics, cultural expectations and social support. CONCLUSIONS: Overall, the fathers in this study reported similar experiences, but this study identified new life perspective as an additional category, which might be specific for fathers of children with disabilities. This new life perspective included a positive attitude, living in the moment, appreciation of the little things and transformation of expectations. Some fathers expressed that their child(ren) has enriched their lives, which positively influenced their fathering experience.

Self-reported oral health problems and the ability to organize dental care of community-dwelling elderly aged ≥75 years.

BACKGROUND: It is unclear how many community-dwelling elderly (≥75 years) experience oral health problems (e.g. pain, dry mouth, chewing problems) and how they manage their dental care needs. This study aimed to assess self-reported oral health problems in elderly who are frail or have complex care needs, and their ability to organize dental care when reporting oral pain. METHODS: Three thousand five hundred thirty-three community-dwelling elderly participating in the "Embrace" project were asked to complete questionnaires regarding oral status and oral health problems. Frailty was assessed with the Groningen Frailty Indicator (GFI). Intermed for Elderly Self-Assessment (IM-E-SA) was used to determine complexity of care needs. Next, elderly who reported oral pain were interviewed about their oral pain complaints, their need for dental care, and their ability to organize and receive dental care. For statistical analyses Chi2-tests and the one-way ANOVA were used. RESULTS: One thousand six hundred twenty-two elderly (45.9%) completed the questionnaires. Dry mouth (11.7%) and oral pain (6.2%) were most frequently reported. Among the elderly reporting oral pain, most were registered at a local dentist and could go there when needed (84.3%). Robust elderly visited the dentist independently (87%), frail (55.6%) and complex (26.9%) elderly more often required assistance from caregivers. CONCLUSIONS: Dry mouth and oral pain are most reported oral health problems among community-dwelling elderly. Elderly with complex care needs report most oral health problems. In case an elderly seeks dental treatment to alleviate an oral pain complaint, most elderly in this study were able to organize dental care and transport to the dentist. Frail and complex elderly often need assistance from caregivers to visit the dentist. Therefore caretakers should keep in mind that when frailty progresses, visiting a dentist may become more and more difficult and the risk for poor oral health increases.

Regional lung densities in alpha-1 antitrypsin deficiency compared to predicted values.

BACKGROUND: We developed a method to calculate a standard score for lung tissue mass derived from CT scan images from a control group without respiratory disease. We applied the method to images from subjects with emphysema associated with alpha-1 antitrypsin deficiency (AATD) and used it to study regional patterns of differential tissue mass. METHODS: We explored different covariates in 76 controls. Standardization was applied to facilitate comparability between different CT scanners and a standard Z-score (Standard Mass Score, SMS) was developed, representing lung tissue loss compared to normal lung mass. This normative data was defined for the entire lungs and for delineated apical, central and basal regions. The agreement with DLCO%pred was explored in a data set of 180 patients with emphysema who participated in a trial of alpha-1-antitrypsin augmentation treatment (RAPID). RESULTS: Large differences between emphysematous and normal tissue of more than 10 standard deviations were found. There was reasonable agreement between SMS and DLCO%pred for the global densitometry (κ = 0.252, p < 0.001), varying from κ = 0.138 to κ = 0.219 and 0.264 (p < 0.001), in the apical, central and basal region, respectively. SMS and DLCO%pred correlated consistently across apical, central and basal regions. The SMS distribution over the different lung regions showed a distinct pattern suggesting that emphysema due to severe AATD develops from basal to central and ultimately apical regions. CONCLUSIONS: Standardization and normalization of lung densitometry is feasible and the adoption of the developed principles helps to characterize the distribution of emphysema, required for clinical decision making.

Predicting factors for chronic colonization of Pseudomonas aeruginosa in bronchiectasis.

About 25% of the patients with bronchiectasis are likely to develop a chronic colonization with Pseudomonas aeruginosa. A better understanding of predictors of acquiring Pseudomonas within the patient population may facilitate future focused research. The aim of this retrospective observational study was to investigate predicting factors for P. aeruginosa colonization in patients with bronchiectasis. This was a single-center retrospective cohort study using a bronchiectasis database which consisted of 211 patients with bronchiectasis. Data were collected for demographic details, etiology, spirometry, microbiology data, maintenance medication use, exacerbation frequency, hospital admission rate, and FACED and Bronchiectasis Severity Index (BSI) score. Two hundred eleven patients were identified from our bronchiectasis database. Overall, 25% of the patients (n = 53) had a chronic colonization with P. aeruginosa. Seventeen patients (8%) died in a 5-year follow-up period of whom 7 (41%) had a chronic P. aeruginosa colonization (p > 0.05). After multiple regression analysis, P. aeruginosa-positive patients were significantly associated with an older age (> 55 years) (p = 0.004), the use of hypertonic saline (0.042), and inhalation antibiotics (< 0.001). Furthermore, the presence of PCD (p < 0.001) and post-infectious etiology (p < 0.001) as underlying causes were significantly associated with P. aeruginosa colonization. We observed that independent predictors for P. aeruginosa colonization were age > 55 years, hypertonic saline, and PCD, and post-infectious etiology as underlying causes of bronchiectasis. Since prevention of P. aeruginosa colonization is an important aim in the treatment of bronchiectasis, more attention could be directed to these groups at risk for Pseudomonas colonization.

[A view on collective oral care for frail older people: united we stand]. / Visie op de collectieve mondzorg voor kwetsbare ouderen: eendracht maakt macht.

Oral health in frail older people is often poor. There are a number of reasons for this, such as increased morbity and decreased motivation for (self) care. Good oral health is, however, very important. Studies have revealed poor oral health to cause or aggravate several medical and psychological problems. Illness and medication can, in turn, damage oral health. Oral health among the elderly should therefore be carefully monitored and maintained. This requires multidisciplinary and interprofessional collaboration on the part of healthcare professionals and others involved. Such collaboration is now still very limited; hardly anything has been written about how such collaboration in the area of oral care for frail older people should or could be organised. This article provides an overview of the possibilities and the relevant factors in the area of oral care for the elderly in promoting collaboration among healthcare professionals and others involved. All of this is under the banner of 'united we stand'.

Effectiveness of 12-13-week scan for early diagnosis of fetal congenital anomalies in the cell-free DNA era.

OBJECTIVES: The main aim of this study was to assess the proportion and type of congenital anomalies, both structural and chromosomal, that can be detected at an early scan performed at 12-13 weeks' gestation, compared with at the 20-week structural anomaly scan offered under the present screening policy. Secondary aims were to evaluate the incidence of false-positive findings and ultrasound markers at both scans, and parental choice regarding termination of pregnancy (TOP). METHODS: Sonographers accredited for nuchal translucency (NT) measurement were asked to participate in the study after undergoing additional training to improve their skills in late first-trimester fetal anatomy examination. The early scans were performed according to a structured protocol, in six ultrasound practices and two referral centers in the north-east of The Netherlands. All women opting for the combined test (CT) or with an increased a-priori risk of fetal anomalies were offered a scan at 12-13 weeks' gestation (study group). All women with a continuing pregnancy were offered, as part of the 'usual care', a 20-week anomaly scan. RESULTS: The study group consisted of 5237 women opting for the CT and 297 women with an increased a-priori risk of anomalies (total, 5534). In total, 51 structural and 34 chromosomal anomalies were detected prenatally in the study population, and 18 additional structural anomalies were detected after birth. Overall, 54/85 (63.5%) anomalies were detected at the early scan (23/51 (45.1%) structural and all chromosomal anomalies presenting with either an increased risk at first-trimester screening or structural anomalies (31/34)). All particularly severe anomalies were detected at the early scan (all cases of neural tube defect, omphalocele, megacystis, and multiple severe congenital and severe skeletal anomalies). NT was increased in 12/23 (52.2%) cases of structural anomaly detected at the early scan. Of the 12 cases of heart defects, four (33.3%) were detected at the early scan, five (41.7%) at the 20-week scan and three (25.0%) after birth. False-positive diagnoses at the early scan and at the 20-week scan occurred in 0.1% and 0.6% of cases, respectively, whereas ultrasound markers were detected in 1.4% and 3.0% of cases, respectively. After first- or second-trimester diagnosis of an anomaly, parents elected TOP in 83.3% and 25.8% of cases, respectively. CONCLUSIONS: An early scan performed at 12-13 weeks' gestation by a competent sonographer can detect about half of the prenatally detectable structural anomalies and 100% of those expected to be detected at this stage. Particularly severe anomalies, often causing parents to choose TOP, are amenable to early diagnosis. The early scan is an essential part of modern pregnancy care. Copyright © 2017 ISUOG.

Reasons for (non)participation in supplemental population-based MRI breast screening for women with extremely dense breasts.

AIM: To determine the willingness of women with extremely dense breasts to undergo breast cancer screening with magnetic resonance imaging (MRI) in a research setting, and to examine reasons for women to participate or not. MATERIALS AND METHODS: Between 2011 and 2015, 8,061 women (50-75 years) were invited for supplemental MRI as part of the Dense Tissue and Early Breast Neoplasm Screening (DENSE) trial (ClinicalTrials.gov Identifier: NCT01315015), after a negative screening mammography in the national population-based mammography screening programme. Demographics of participants and non-participants were compared. All invitees were asked to report reasons for (non)participation. Ethical approval was obtained. Participants provided written informed consent. RESULTS: Of the 8,061 invitees, 66% answered that they were interested, and 59% eventually participated. Participants were on average 54-years old (interquartile range: 51-59 years), comparable to women with extremely dense breasts in the population-based screening programme (55 years). Women with higher socio-economic status (SES) were more often interested in participation than women with lower SES (68% versus 59%, p<0.001). The most frequently stated reasons for non-participation were "MRI-related inconveniences and/or self-reported contraindications to MRI" (27%) and "anxiety regarding the result of supplemental screening" (21%). "Expected personal health benefit" (68%) and "contribution to science" (43%) were the most frequent reasons for participation. CONCLUSION: Of women invited for MRI because of extremely dense breasts, 59% participated. Common reasons for non-participation were "MRI-related inconveniences" and "anxiety regarding the result of supplemental screening". In case of future implementation, availability of precise evidence on benefits and harms might reduce this anxiety.

Practitioner Review: Psychological treatments for children and adolescents with conduct disorder problems - a systematic review and meta-analysis.

BACKGROUND: This meta-analysis evaluates the efficacy of nonpharmacological treatments for conduct disorder (CD) problems in children and adolescents, based on child, parent and teacher report. METHODS: PubMed, PsycINFO and EMBASE were searched for peer-reviewed articles published between January 1970 and March 2015. Main inclusion criteria were nonpharmacological treatment, participants younger than 18 years, clinical CD problems/diagnosis, randomized controlled trials and inclusion of at least one CD problem-related outcome. Treatment efficacy is expressed in effect sizes (ESs) calculated for each rater (parent, teacher, self and blinded observer). RESULTS: Of 1,549 articles retrieved, 17 (published between June 2004 and January 2014) describing 19 interventions met the inclusion criteria. All studies used psychological treatments; only three studies included a blinded observer to rate CD problems. Most studies were of very poor to fair quality. ESs were significant but small for parent-reported outcomes (0.36, 95% CI = 0.27-0.47), teacher-reported outcomes (0.26, 95% CI = 0.12-0.49) and blinded observer outcomes (0.26, 95% CI = 0.06-0.47), and they were nonsignificant for self-reported outcomes (-0.01, 95% CI = -0.25 to 0.23). Comorbidity, gender, age, number of sessions, duration, intervention type, setting, medication use or dropout percentage did not influence the effect of treatment. CONCLUSIONS: Psychological treatments have a small effect in reducing parent-, teacher- and observer-rated CD problems in children and adolescents with clinical CD problems/diagnosis. There is not enough evidence to support one specific psychological treatment over another. Future studies should investigate the influence of participant characteristics (e.g. age of CD onset), use more homogeneous outcome measures and allow better evaluation of study quality. Many reports failed to provide detailed information to allow optimization of psychological treatment strategies.
