Fair allocation of cryopreserved donor oocytes: towards an accountable process.

A growing number of people desire ART with cryopreserved donor oocytes. The allocation of these oocytes to couples and mothers to be is a 2-fold process. The first step is to select a pool of recipients. The second step is to decide who should be treated first. Prioritizing recipients is critical in settings where demand outstrips supply. So far, the issue of how to fairly allocate cryopreserved donor oocytes has been poorly addressed. Our ethical analysis aims to support clinics involved in allocation decisions by formulating criteria for recipient selection irrespective of supply (Part I) and recipient prioritization in case supply is limited (Part II). Relevant criteria for recipient selection are: a need for treatment to experience parenthood; a reasonable chance for successful treatment; the ability to safely undergo an oocyte donation pregnancy; and the ability to establish a stable and loving relationship with the child. Recipients eligible for priority include those who: have limited time left for treatment; have not yet experienced parenthood; did not undergo previous treatment with cryopreserved donor oocytes; and contributed to the supply of donor oocytes by bringing a donor to the bank. While selection criteria function as a threshold principle, we argue that the different prioritization criteria should be carefully balanced. Since specifying and balancing the allocation criteria undoubtedly raises a moral dispute, a fair and legitimate allocation process is warranted (Part III). We argue that allocation decisions should be made by a multidisciplinary committee, staffed by relevant experts with a variety of perspectives. Furthermore, the committees' reasoning behind decisions should be transparent and accessible to those affected: clinicians, donors, recipients and children born from treatment. Insight into the reasons that underpin allocation decisions allows these stakeholders to understand, review and challenge decisions, which is also known as accountability for reasonableness.

Fertility-sparing surgery and fertility preservation in cervical cancer: The desire for parenthood, reproductive and obstetric outcomes.

OBJECTIVE: To evaluate the desire for parenthood and reproductive outcomes of young cervical cancer survivors who underwent fertility-sparing surgery or fertility preservation procedures for invasive cervical cancer. METHODS: All women <45 years who underwent fertility-sparing treatment for invasive cervical cancer in a tertiary referral center in the Netherlands between January 2009 and January 2020 were identified. Fertility-sparing treatment options included Vaginal Radical Trachelectomy (VRT) for patients with early-stage disease and fertility preservation techniques (FP) when requiring Radical Hysterectomy (RH) or chemoradiotherapy. Data on reproductive intentions - and outcomes were retrieved from medical files and questionnaires. RESULTS: 75 patients were identified of whom 34 underwent VRT, 9 RH and 32 had (chemo)radiotherapy. 26 patients started FP of whom 23 (88.5%) successfully preserved fertility through cryopreservation of embryos, oocytes and ovarian tissue. After a median follow-up of 49 months, 5 patients developed recurrent disease and died. Reproductive outcomes were retrieved in 58 patients. 89.6% maintained their desire for parenthood after cancer treatment. Following VRT, we report a pregnancy rate of 61.9% among the patients attempting conception (n = 24). 15 patients conceived 21 pregnancies which resulted in 15 live-births, yielding a live-birth rate of 75.0%. Following RH or (chemo)radiotherapy, 3 surrogate pregnancies were established (21.4%) using frozen-thawed material with good neonatal outcomes. CONCLUSION: Many cervical cancer survivors maintain the desire to become parents eventually. In early-stage disease, VRT shows good reproductive outcomes without compromising oncological safety. For those requiring gonadotoxic treatment fertility preservation and gestational surrogacy provides a promising alternative for achieving a biological offspring.

The ethics of embryo donation: what are the moral similarities and differences of surplus embryo donation and double gamete donation?

Over the years, the demand for ART with donated embryos has increased. Treatment can be performed using donated 'surplus embryos' from IVF treatment or with embryos intentionally created through so-called 'double gamete donation'. Embryo donation is particularly sensitive because treatment results in the absence of a genetic link between the parent(s) and the child, creating complex family structures, including full genetic siblings living in another family in the case of surplus embryo donation. In this paper, we explore the ethical acceptability of embryo donation in light of the similarities and differences between surplus embryo donation and double gamete donation. We will argue that no overriding objections to either form of embryo donation exist. First of all, ART with donated embryos respects patients' reproductive autonomy by allowing them to experience gestational parenthood. It also respects IVF patients' reproductive autonomy by providing an additional option to discarding or donating surplus embryos to research. Second, an extensive body of empirical research has shown that a genetic link between parent and child is not a condition for a loving caring relationship between parent(s) and child. Third, the low moral status of a pre-implantation embryo signifies no moral duty for clinics to first use available surplus embryos or to prevent the development of (more) surplus embryos through double gamete donation. Fourth, there is no reason to assume that knowledge of having (full or half) genetically related persons living elsewhere provides an unacceptable impact on the welfare of donor-conceived offspring, existing children of the donors, and their respective families. Thus, patients and clinicians should discuss which form of ART would be suitable in their specific situation. To guarantee ethically sound ART with donated embryos certain conditions have to be met. Counselling of IVF patients should involve a discussion on the destination of potential surplus embryos. When counselling donors and recipient(s) a discussion of the significance of early disclosure of the child's mode of conception, the implications of having children raised in families with whom they share no genetic ties, expectations around information-exchange and contact between donor and recipient families or genetically related siblings is warranted. Importantly, conclusions are mainly drawn from results of empirical studies on single gamete donation families. To evaluate the welfare of families created through surplus embryo donation or double gamete donation additional empirical research on these particular families is warranted.

MRI cT1-2 rectal cancer staging accuracy: a population-based study.

BACKGROUND: Adequate MRI-based staging of early rectal cancers is essential for decision-making in an era of organ-conserving treatment approaches. The aim of this population-based study was to determine the accuracy of routine daily MRI staging of early rectal cancer, whether or not combined with endorectal ultrasonography (ERUS). METHODS: Patients with cT1-2 rectal cancer who underwent local excision or total mesorectal excision (TME) without downsizing (chemo)radiotherapy between 1 January 2011 and 31 December 2018 were selected from the Dutch ColoRectal Audit. The accuracy of imaging was expressed as sensitivity, specificity, and positive predictive value (PPV) and negative predictive value. RESULTS: Of 7382 registered patients with cT1-2 rectal cancer, 5539 were included (5288 MRI alone, 251 MRI and ERUS; 1059 cT1 and 4480 cT2). Among patients with pT1 tumours, 54·7 per cent (792 of 1448) were overstaged by MRI alone, and 31·0 per cent (36 of 116) by MRI and ERUS. Understaging of pT2 disease occurred in 8·2 per cent (197 of 2388) and 27·9 per cent (31 of 111) respectively. MRI alone overstaged pN0 in 17·3 per cent (570 of 3303) and the PPV for assignment of cN0 category was 76·3 per cent (2733 of 3583). Of 834 patients with pT1 N0 disease, potentially suitable for local excision, tumours in 253 patients (30·3 per cent) were staged correctly as cT1 N0, whereas 484 (58·0 per cent) and 97 (11·6 per cent) were overstaged as cT2 N0 and cT1-2 N1 respectively. CONCLUSION: This Dutch population-based analysis of patients who underwent local excision or TME surgery for cT1-2 rectal cancer based on preoperative MRI staging revealed substantial overstaging, indicating the weaknesses of MRI and missed opportunities for organ preservation strategies.

ANTECEDENTES: Una adecuada estadificación mediante resonancia magnética nuclear (RMN) de los cánceres de recto en estadios precoces es esencial para la toma de decisiones en una era en la existen diferentes opciones de tratamiento preservadoras del recto. El objetivo de este estudio de base poblacional fue determinar la precisión de la estadificación mediante RMN del cáncer de recto precoz en la práctica diaria, ya sea combinada o no con la ecografía endorectal (endorectal ultrasound, ERUS). MÉTODOS: Los pacientes con cáncer de recto en estadio cT1-2 que se sometieron a resección local o resección total del mesorrecto (total mesorectal excision, TME) sin (quimio) radioterapia neoadyuvante fueron seleccionados a partir del registro auditado ColoRectal holandés, entre el 1 de enero de 2011 y el 31 de diciembre de 2018. La precisión de las imágenes se expresó como sensibilidad, especificidad y valores predictivos positivo y negativo (positive- and negative predicting value, PPV / NPV). RESULTADOS: De un total de 7.382 pacientes registrados con cáncer de recto en estadio cT1-2, se incluyeron 5.539 pacientes (5.288 solamente RMN, 251 RMN + ERUS; 1.059 cT1 y 4.480 cT2). Los pacientes pT1 fueron sobreestadificados cuando se utilizó únicamente la RMN en un 54,7% de los casos (792/1.448) y cuando se combinó RMN y ERUS en un 31,0% (36/116). La infraestadificación de pT2 ocurrió en un 8,2% (197/2.388) y en un 27,9% (31/111), respectivamente. La RMN utilizada como única prueba sobreestadificó los casos pN0 en el 17,3% (570/3.303) y el VPP del estadio cN0 fue del 76,3% (2.733/3.583). De los 834 pacientes con estadio pT1N0, potencialmente adecuado para la resección local, 253 pacientes (30,3%) se clasificaron correctamente como cT1N0, y 484 (58,8%) y 97 (11,6%) pacientes se sobreestadificaron como cT2N0 y cT1-2N1, respectivamente. CONCLUSIÓN: Este estudio de base poblacional holandés en pacientes que se sometieron a una resección local o a cirugía TME por cáncer de recto cT1-2 con estadificación preoperatoria mediante RMN, muestra una considerable sobreestadificación, lo que indica las debilidades y oportunidades en las estrategias de preservación del recto.

Stakeholders views on the ethical aspects of oocyte banking for third-party assisted reproduction: a qualitative interview study with donors, recipients and professionals.

STUDY QUESTION: What are the moral considerations held by donors, recipients and professionals towards the ethical aspects of the intake and distribution of donor bank oocytes for third-party assisted reproduction? SUMMARY ANSWER: Interviews with oocyte donors, oocyte recipients and professionals demonstrate a protective attitude towards the welfare of the donor and the future child. WHAT IS KNOWN ALREADY: The scarcity of donor oocytes challenges the approach towards the many ethical aspects that arise in establishing and operating an oocyte bank for third-party assisted reproduction. Including experiences and moral considerations originating from practice provides useful insight on how to overcome these challenges. STUDY DESIGN, SIZE, DURATION: The project was set-up as a qualitative interview study and took place between October 2016 and August 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: We conducted 25 semi-structured interviews with professionals engaged in the practice of oocyte banking (n = 10), recipients of donor oocytes (n = 7) and oocyte donors (n = 8). Key themes were formulated by means of a thematic analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Based on the interviews, we formulated four main themes describing stakeholders' views regarding the ethical aspects of the intake and distribution of donor bank oocytes. First, respondents articulated that when selecting donors and recipients, healthcare workers should prevent donors from making a wrong decision and safeguard the future child's well-being by minimizing health risks and selecting recipients based on their parental capabilities. Second, they proposed to provide a reasonable compensation and to increase societal awareness on the scarcity of donor oocytes to diminish barriers for donors. Third, respondents considered the prioritization of recipients in case of scarcity a difficult choice, because they are all dependent on donor oocytes to fulfil their wish for a child. They emphasized that treatment attempts should be limited, but at least include one embryo transfer. Fourth and finally, the importance of good governance of oocyte banks was mentioned, including a homogenous policy and the facilitation of exchange of experiences between oocyte banks. LIMITATIONS, REASONS FOR CAUTION: The possibility of selection bias exists, because we interviewed donors and recipients who were selected according to the criteria currently employed in the clinics. WIDER IMPLICATIONS OF THE FINDINGS: Respondents' moral considerations regarding the ethical aspects of the intake and distribution of donor oocytes demonstrate a protective attitude towards the welfare of the donor and the future child. At the same time, respondents also questioned whether such a (highly) protective attitude was justified. This finding may indicate there is room for reconsidering strategies for the collection and distribution of donor bank oocytes.

Growth patterns and cerebroplacental hemodynamics in fetuses with congenital heart disease.

OBJECTIVES: Congenital heart disease (CHD) has been associated with reduced fetal head circumference (HC), although the underlying pathophysiology remains undetermined. We aimed to define trends in fetal growth and cerebroplacental Doppler flow, and to investigate their relationship, in fetuses with CHD. METHODS: This was a retrospective study in two fetal medicine units in The Netherlands. We included all fetuses with CHD in whom Doppler flow patterns (middle cerebral artery (MCA) pulsatility index (PI), umbilical artery (UA) PI and cerebroplacental ratio (CPR)) and biometry (HC and abdominal circumference (AC)) had been measured serially after 19 weeks' gestation between January 2010 and November 2016. Fetuses were categorized into three groups based on the expected cerebral arterial oxygen saturation of their particular type of CHD: normal; mild to moderately reduced; severely reduced. Trends over time in Z-scores were analyzed using a linear mixed-effects model. RESULTS: A total of 181 fetuses fulfilled the inclusion criteria. Expected cerebral arterial oxygen saturation in CHD was classified as normal in 44 cases, mild to moderately reduced in 84 and severely reduced in 53. In the cohort overall, average trends over time were significant for both HC and AC Z-scores. HC Z-scores showed a tendency to decrease until 23 weeks, then to increase until 33 weeks, followed by another decrease in the late third trimester. AC Z-scores increased progressively with advancing gestation. MCA-PI and UA-PI Z-scores showed significant trends throughout pregnancy, but CPR Z-scores did not. There were no associations between expected cerebral arterial oxygen saturation and fetal growth. Average trends in MCA-PI Z-scores were significantly different between the three subgroups, whereas those in UA-PI Z-scores and in CPR Z-scores were similar between the subgroups. There was no significant association between MCA-PI and HC Z-scores. CONCLUSIONS: Fetal biometry and Doppler flow patterns are within normal range in fetuses with CHD, but show trends over time. Head growth in fetuses with CHD is not associated with cerebral blood flow pattern or placental function and HC is not influenced by the cerebral arterial oxygen saturation. © 2018 The Authors.

Treatment and Outcome of Synchronous Colorectal Carcinomas: A Nationwide Study.

BACKGROUND: Synchronous colorectal carcinomas (CRC) occur in 1-8% of patients diagnosed with CRC. This study evaluated treatment patterns and patient outcomes in synchronous CRCs compared with solitary CRC patients. METHODS: All patients diagnosed with primary CRC between 2008 and 2013, who underwent elective surgery, were selected from the Netherlands Cancer Registry. Using multivariable regressions, the effects of synchronous CRC were assessed for both short-term outcomes (prolonged postoperative hospital admission, anastomotic leakage, postoperative 30-day mortality, administration of neoadjuvant or adjuvant treatment), and 5-year relative survival (RS). RESULTS: Of 41,060 CRC patients, 1969 patients (5%) had synchronous CRC. Patients with synchronous CRC were older (mean age 71 ± 10.6 vs. 69 ± 11.4 years), more often male (61 vs. 54%), and diagnosed with more advanced tumour stage (stage III-IV 54 vs. 49%) compared with solitary CRC (all p < 0.0001). In 50% of the synchronous CRCs, an extended surgery was conducted (n = 934). Synchronous CRCs with at least one stage II-III rectal tumour less likely received neoadjuvant (chemo)radiation [78 vs. 86%; adjusted OR 0.6 (0.48-0.84)], and synchronous CRCs with at least one stage III colon tumour less likely received adjuvant chemotherapy [49 vs. 63%; adjusted OR 0.7 (0.55-0.89)]. Synchronous CRCs were independently associated with decreased survival [RS 77 vs. 71%; adjusted RER 1.1 (1.01-1.23)]. CONCLUSIONS: The incidence of synchronous CRCs in the Dutch population is 5%. Synchronous CRCs were associated with decreased survival compared with solitary CRC. The results emphasize the importance of identifying synchronous tumours, preferably before surgery to provide optimal treatment.

Alpha particle spectroscopy using FNTD and SIM super-resolution microscopy.

Structured illumination microscopy (SIM) for the imaging of alpha particle tracks in fluorescent nuclear track detectors (FNTD) was evaluated and compared to confocal laser scanning microscopy (CLSM). FNTDs were irradiated with an external alpha source and imaged using both methodologies. SIM imaging resulted in improved resolution, without increase in scan time. Alpha particle energy estimation based on the track length, direction and intensity produced results in good agreement with the expected alpha particle energy distribution. A pronounced difference was seen in the spatial scattering of alpha particles in the detectors, where SIM showed an almost 50% reduction compared to CLSM. The improved resolution of SIM allows for more detailed studies of the tracks induced by ionising particles. The combination of SIM and FNTDs for alpha radiation paves the way for affordable and fast alpha spectroscopy and dosimetry.

Feedback to Patients About Patient-reported Outcomes Does Not Improve Empowerment or Satisfaction.

BACKGROUND: Although patient-reported outcome measures (PROMs) are helpful to define whether an intervention has improved a patient's status in ways the patient feels are important, they may also serve an empowering educational role; specifically, sharing a patient's scores might help the patient understand his or her progress during treatment. However, whether sharing PROM scores in this way improves the sense of empowerment or satisfaction with the process of care has not been well explored. Also, less is known whether specific demographic factors or coping strategies are associated with empowerment. QUESTIONS/PURPOSES: We asked the following: (1) Does giving patients feedback on their PROM scores improve a patient's sense of empowerment or satisfaction? (2) Do demographic factors, duration of disability, or self-efficacy correlate with patient empowerment? METHODS: In this prospective cohort study, we assigned patients with osteoarthritis of the knee or hip sequentially such that the first 70 patients did not receive the intervention and the next 72 did. Patients enrolled in the control cohort were managed according to standard care, whereas patients enrolled in the intervention cohort completed web-based questionnaires measuring their physical function and pain. After filling out the questionnaires, a printout with the scores was given to the patients providing feedback about their physical function and pain. The primary outcome measure was patient empowerment, as measured by the Patient Activation Measure. Secondary outcomes were patient satisfaction, as measured by an 11-point Likert scale and Patient Doctor Relation Questionnaire. Independent variables were demographic factors and coping, measured by the Pain Self-efficacy Questionnaire. Bivariate and multivariable analyses were performed to determine the influence of the feedback. Although no minimum clinically important differences have been defined for the patient empowerment or satisfaction scales, we believe that differences smaller than 10% are unlikely to be clinically important, even if they are statistically significant. RESULTS: Although the group that received PROM feedback had higher scores for empowerment than the group that did not, the effect size was small and likely not to have been clinically important (2.8 ± 0.85 versus 3.1 ± 0.811; mean difference -0.31; 95% confidence interval, 2.8-3.1; p = 0.037). With the numbers available, there were no differences between the group given PROM feedback and the group that did not receive such feedback in terms of satisfaction scores (8.6 ± 1.4 versus 8.8 ± 1.2; mean difference -0.19; p = 0.39). After controlling for demographic factors such as level of education and duration of complaint, we found that the group that received PROM feedback and who had a higher level of self-efficacy had higher scores for empowerment than the group that did not, although the effect size was small. CONCLUSIONS: PROM feedback did not have a clinically important impact on empowerment or satisfaction. This might indicate that counseling based on PROMs during a single visit may be ineffective. The most important positive finding is that more effective coping strategies are associated with greater patient empowerment. LEVEL OF EVIDENCE: Level II, therapeutic study.

Amplitude-Integrated EEG and Cerebral Near-Infrared Spectroscopy in Cooled, Asphyxiated Infants.

OBJECTIVE: To assess the predictive value of amplitude-integrated electroencephalography EEG (aEEG) and near-infrared spectroscopy (NIRS) during therapeutic hypothermia. PATIENTS AND METHODS: We studied 39 cooled, asphyxiated infants. We assessed aEEG and calculated mean regional cerebral oxygen saturation (rcSO2) during and after treatment. At 30 months, we performed a neurological examination and administered the Bayley Scales of Infant and Toddler Development, 3rd edition. We calculated the odds ratios (ORs) of abnormal aEEG and rcSO2 for severely abnormal outcome. RESULTS: At 6 and 12 hours, severely abnormal aEEGs predicted severely abnormal outcomes (OR, 7.7 [95% confidence interval, CI, 1.39-42.6] and 24.4 [95% CI 4.2-143] respectively), as did epileptic activity (OR 28.9, 4.6-183). During the first 48 hours, rcSO2 was not associated with outcome, but at 72 hours after birth and after rewarming it was, with ORs for severely abnormal outcomes of 12.8 (1.31-124) and 21.6 (1.05-189), respectively. In multivariate analyses, aEEG and rcSO2 remained independently predictive in the model at 48 hours and significantly from 72 hours after birth onward. CONCLUSION: aEEG was a strong predictor of adverse outcome. After 48 hours of cooling, a higher rcSO2 was associated with a severely abnormal outcome, adding to the predictive value of aEEG in cooled, asphyxiated infants.

[Vision on man, vision on addiction: a multiple view of problems and recovery]. / Visie op de mens, visie op verslaving: een meervoudige kijk op problematiek en herstel.

BACKGROUND: The way we look at addiction has changed dramatically over the past decades. Currently, the brain disease model is the leading model in the biomedical scientific literature. However, this model has been severely criticized and seems to apply mostly to people with a chronic form of addiction. When the ideas of the recovery movement are applied to the current understanding of addiction, the biopsychosocial (bps) model seems the most fitting. On the other hand, while 'meaningful existence' (or 'sense of meaning') is a focal element the model of recovery, this concept is not included in the bps model.
AIM: To explore whether addition of the concept of meaning to the bps model is usefull.
METHOD: Discussion of a case and evaluation of selected literature.
RESULTS: We advocate the addition of the concept 'sense of meaning' to the bps model, making it the bpsm model. A matter still to be resolved is whether this concept would become a fourth domain or considered either subjacent to or above the other three domains. We suggest that, while sense of meaning is not new in addiction care, adding this concept would underline the importance of the personal story behind the addiction.
CONCLUSION: Addition of the concept meaning to the bps model is Usefull in addiction care.

[Recognising and reporting child abuse by orthodontists]. / Herkenning en melding van kindermishandeling door orthodontisten.

In 2013, the child abuse and domestic violence reporting code was introduced in the Netherlands, which obliged caregivers to report suspicions of child abuse or domestic violence. In 2014, a survey was conducted among dentists on this subject. However, nothing was known about the use of the reporting code among orthodontists. In December 2015, a survey was sent to members of the Dutch Orthodontic Society (NVvO). The survey consisted of 20 items about applying the reporting code and experiences with patients. Most orthodontists were aware of the reporting code (83%) and had implemented this in their practice (64%). Nevertheless, orthodontists found it difficult to recognise signs of child abuse, mostly because of a lack of experience in this area. Most orthodontists who suspected child abuse took action, mainly by seeking advice from the foundation 'Veilig Thuis' ('Safe at Home').

Multicentre evaluation of the new ORTHO VISION® analyser.

BACKGROUND: Implementation of fully automated analysers has become a crucial security step in the blood bank; it reduces human errors, allows standardisation and improves turnaround time (TAT). OBJECTIVES: We aimed at evaluating the ease of use and the efficiency of the ORTHO VISION® Analyser (VISION) in comparison to the ORTHO AutoVue® Innova System (AutoVue) in six different laboratories. METHODS: After initial training and system configuration, VISION was used in parallel to AutoVue following the daily workload, both automates being based on ORTHO BioVue® System column agglutination technology. Each participating laboratory provided data and scored the training, system configuration, quality control, maintenance and system efficiency. A total of 1049 individual samples were run: 266 forward and reverse grouping and antibody screens with 10 urgent samples, 473 ABD forward grouping and antibody screens with 22 urgent samples, 160 ABD forward grouping, 42 antibody screens and a series of 108 specific case profiles. RESULTS: The VISION instrument was more rapid than the AutoVue with a mean performing test time of 27·9 min compared to 36 min; for various test type comparisons, the TAT data obtained from VISION was shorter than that from AutoVue. Moreover, VISION analysed urgent STAT samples faster. Regarding the ease of use, VISION was intuitive and user friendly. CONCLUSIONS: VISION is a robust, reproducible system performing the most types of analytical determinations needed for pre-transfusion testing today, thus accommodating a wide range of clinical needs. VISION brings appreciated new features that could further secure blood transfusions.

The role of Indonesian patients' health behaviors in delaying the diagnosis of nasopharyngeal carcinoma.

BACKGROUND: With an estimated 13,000 newly diagnosed patients per year, nasopharyngeal carcinoma (NPC) is one of the most common types of cancer in males in Indonesia. Moreover, most patients are diagnosed at an advanced stage of the disease. This study aimed to explore the health behaviors of patients diagnosed with NPC and the possible causes of patient delay in NPC diagnosis. METHODS: A qualitative research method was used to gain better insight into patient behaviors. Twelve patients were interviewed using semi-structured interview guidelines. All interviews were recorded, transcribed verbatim and analyzed according to a standard content analysis framework. RESULTS: Most patients had limited knowledge regarding NPC and its causes. Fifty percent of the patients had a delay of six months from the onset of symptoms to diagnosis. The main reason for this delay was the lack of awareness among the patients, which was influenced by their environment, economic status, family, culture, and religion. The perceived barriers to seeking medical help included direct non-medical costs not covered by health insurance, complex and time-consuming insurance and referral systems, and negative experiences in the past. Health insurance did motivate people to seek medical help. CONCLUSION: This study provides additional insight into patients' motivations to delay seeking medical help and can facilitate the design of NPC education programs. To improve awareness of the abovementioned causes for delay, community-based education programs are highly warranted and should focus on the recognition of NPC symptoms and possible solutions to overcome the main barriers at an earlier disease stage.

Relationship between general movements in neonates who were growth restricted in utero and prenatal Doppler flow patterns.

OBJECTIVE: To investigate whether Doppler pulsatility indices (PIs) of the fetal circulation in cases of fetal growth restriction (FGR) are associated with the general movements (GMs) of the neonate after birth. METHODS: This was a prospective observational cohort study including pregnancies with FGR diagnosed between June 2012 and September 2014. A diagnosis of FGR was based on an abdominal circumference or estimated fetal weight < 10th percentile (in conjuction with abnormal Doppler) or declining fetal growth of at least 30 percentiles with respect to previous size measurements. Doppler parameters of the umbilical artery (UA), fetal middle cerebral artery (MCA) and ductus venosus (DV) were measured maximally 1 week prior to delivery. Cerebroplacental ratio (CPR) was calculated as MCA-PI divided by UA-PI. We assessed the quality of neonatal GMs 7 days after birth, around the due date if cases were born preterm, and at 3 months post-term. We performed a detailed analysis of the motor repertoire by calculating a motor optimality score (MOS). RESULTS: Forty-eight FGR cases were included with a median gestational age at delivery of 35 (range, 26-40) weeks. UA-PI, MCA-PI and CPR correlated strongly (ρ, -0.374 to 0.472; P < 0.01) with the MOS on day 7 after birth, but DV-PI did not. Doppler PI measurements did not correlate with MOS at 3 months post-term. CONCLUSION: Fetal arterial Doppler measurements are associated with the quality of neonatal GMs 1 week after birth, but this association is no longer evident at 3 months post-term. Brain sparing in particular is associated strongly with GMs of an abnormal quality. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Correlation between Doppler flow patterns in growth-restricted fetuses and neonatal circulation.

OBJECTIVES: To investigate whether prenatal Doppler parameters in growth-restricted fetuses are correlated with neonatal circulatory changes. METHODS: In 43 cases of suspected fetal growth restriction (FGR), serial Doppler measurements of umbilical artery (UA) and middle cerebral artery (MCA) pulsatility index (PI) were performed. The last measurement, closest to delivery (< 1 week before birth), was used for analysis. Neonatal circulation was assessed for 2 h/day on Days 1-5, 8 and 15 by near-infrared spectroscopy (NIRS) of the cerebral, renal and splanchnic regions. We calculated fractional tissue oxygen extraction (FTOE) as: (arterial oxygen saturation - NIRS value)/arterial oxygen saturation. The following ratios were calculated: cerebroplacental ratio (CPR; MCA-PI/UA-PI), cerebrorenal ratio (CRR; cerebral/renal FTOE) and cerebrosplanchnic ratio (CSR; cerebral/splanchnic FTOE). Spearman's rank correlation coefficient (ρ) was calculated between prenatal Doppler parameters and neonatal NIRS variables. These analyses were carried out for the entire group, and separately for cases of early FGR (delivered < 34 weeks) and late FGR (≥ 34 weeks). RESULTS: Fetal Doppler parameters correlated with neonatal NIRS variables on Days 1-3: UA-PI correlated with renal FTOE (Day 1: ρ = 0.454, P < 0.01) and CRR (Day 1: ρ = -0.517, P < 0.001). MCA-PI correlated with cerebral FTOE on Day 2 (ρ = 0.469, P < 0.01), approached statistical significance on Day 3 but was not correlated on Day 1. CPR correlated with CRR (Day 1: ρ = 0.474, P < 0.01). Most associations lost their statistical significance when early and late FGR subgroups were considered separately. CONCLUSION: Low MCA-PI and low CPR, indicating brain sparing before birth, are associated with low CRR after birth, indicating relatively greater blood flow to the cerebrum than to the renal region. Based on the results of this study, it could be speculated that if brain sparing is present in the fetal circulation, it persists during the first 3 days after birth. Copyright © 2015 ISUOG.

Patient adherence in orthodontics: a protocol for a scoping review.

BACKGROUND: Patient adherence is a key factor in achieving orthodontic success. While in recent years there have been changes in orthodontic healthcare, no recent comprehensive reviews regarding adherence in orthodontics are available. Therefore, the aim of this planned scoping review is to systematically map the available literature regarding patient adherence in orthodontics to identify factors associated with patient adherence and to investigate if there are knowledge gaps in the available literature. METHODS/DESIGN: This protocol was drafted according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) statement and the PRISMA extension for Scoping Reviews (PRISMA-ScR). For the methods Arksey and O'Malley's framework and the Reviewer's Manual of the Joanna Briggs Institute for conducting scoping reviews were consulted. The inclusion criteria for this scoping review are studies of all designs assessing any form of adherence in orthodontics, published in English from 2006 onwards. The exclusion criteria are studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those solely treated for obstructive sleep apnoea. Case reports and studies published in non peer reviewed journals will also be excluded. The following electronic databases will be searched: Embase, PubMed, and Web of Science Core Collection. The following key terms will be used in the search strategies: 'treatment adherence and compliance', and 'orthodontics'. Multiple reviewers will independently screen the results and perform the data charting process. A narrative description will be provided for the analysis of the included studies. The results will be categorized into multiple topics based on recommendations by previous studies into patient adherence. Identified knowledge gaps will be reported and recommendations for future research will be suggested. DISCUSSION: No systematic review has previously assessed this exact topic. Because of the broad-spectrum research questions and the expected widely scattered literature a scoping review approach was chosen over a systematic review approach. The Academic Centre for Dentistry Amsterdam (ACTA) has been conducting research in patient adherence in orthodontics up to 2006 and therefore only studies published from 2006 onwards will be researched in this review. Identifying knowledge gaps and summarizing and disseminating research findings on this topic is important for every dental professional performing orthodontic treatment.

Neurocognitive outcomes in moderately preterm born adolescents.

BACKGROUND: Early preterm (EP) born children are at risk of neurocognitive impairments persisting into adulthood. Less is known about moderately to late (MLP) preterm born children, especially after early childhood. The aim of this study was to assess neurocognitive functioning of MLP adolescents regarding intelligence, executive and attentional functioning, compared with EP and full-term (FT) adolescents. METHODS: This study was part of the Longitudinal Preterm Outcome Project (LOLLIPOP), a large community-based observational cohort study. In total 294 children (81 EP, 130 MLP, and 83 FT) were tested at age 14 to 16 years, regarding intelligence, speed of processing, attention, and executive functions. We used the Dutch version of the Wechsler Intelligence Scale for Children-Third Edition-Dutch Version (WISC-III-NL), the Test of Everyday Attention for Children, and the Behavioural Assessment of the Dysexecutive Syndrome for Children. We assessed differences between preterm-born groups with the FT group as a reference. RESULTS: Compared to the FT group, MLP adolescents scored significantly lower on two subtasks of the WISC-III-NL, i.e. Similarities and Symbol Search. EP adolescents performed significantly lower on all neuropsychological tests than their FT peers, except for the subtask Vocabulary. The MLP adolescents scored in between FT and EP adolescents on all tasks, except for three WISC-III-NL subtasks. CONCLUSIONS: Neurocognitive outcomes of MLP adolescents fell mostly in between outcomes of their EP and FT peers. MLPs generally performed on a low-average to average level, and appeared susceptible to a variety of moderate neurodevelopmental problems at adolescent age, which deserves attention in clinical practice.

The effect of preimplantation genetic screening on neurological, cognitive and behavioural development in 4-year-old children: follow-up of a RCT.

STUDY QUESTION: Does embryo biopsy inherent to preimplantation genetic screening (PGS) affect neurological, cognitive and behavioural development of 4-year-old children? SUMMARY ANSWER: PGS does not seem to affect neurological, cognitive and behavioural development of 4-year-old singletons; however, our data suggest that it may be associated with altered neurodevelopment in twins. WHAT IS KNOWN ALREADY: Evidence concerning the safety of PGS on neurodevelopmental outcome in offspring is scarce. The present study provides information on neurodevelopmental, cognitive and behavioural outcome of 4-year-old PGS offspring. STUDY DESIGN, SIZE, DURATION: A prospective, assessor-blinded follow-up study of children born to women who participated in a multi-centre RCT on the effect of IVF with or without PGS. PARTICIPANTS/MATERIALS, SETTING, METHODS: At 4 years, 49 children (31 singletons, 9 sets of twins) born following IVF with PGS and 64 children (42 singletons, 11 sets of twins) born following IVF without PGS (controls) were assessed (post-natal attrition 18%). Neurological development was evaluated with the standardized, age-specific and sensitive neurological examination according to Hempel, resulting in a neurological optimality score (NOS), a fluency score and the rate of adverse neurological outcome. Primary outcome was the fluency score, as fluency of movements is easily reduced by subtle dysfunction of the brain. Cognitive development was evaluated with the Kaufman Assessment Battery for Children; behavioural development was evaluated with the Child Behavior Checklist. The effect of PGS was analysed with a mixed effects model. MAIN RESULTS AND THE ROLE OF CHANCE: Based on the intention to treat analysis, neurodevelopmental outcome of PGS children was similar to that of controls. However, additional analyses indicated that PGS affected neurodevelopmental outcome of twins in a different way than that of singletons. The fluency score of singletons born following PGS was similar to that of control singletons [mean values, 95% confidence intervals (CIs): 12.2 (11.5;12.8) and 12.2 (11.6;12.8)], respectively, P = 0.977) that was also true for the other neurodevelopmental parameters. The fluency score of PGS twins was significantly lower than that of control twins [mean values, 95% CIs: 10.6 (9.8;11.3) and 12.3 (11.5;13.1)], respectively, P = 0.001); the same was true for the NOS. In addition, PGS in twins was associated with a higher sequential intelligence quotient score. On the other hand, other neurodevelopmental parameters were similar for PGS twins and control twins. Post hoc sample size calculation for the primary outcome parameter, the fluency score, indicated that the study groups, including the subgroups of singletons and twins, were adequately powered. LIMITATIONS, REASONS FOR CAUTION: We assessed singletons and twins who contributed to the generalizability of the study. A limitation of our study is the relative small size of our study groups and the selective dropout in both groups (dropouts PGS group: higher gestational age; control group: less well-educated parents). These preclude the conclusion that PGS per se is not associated with neurodevelopmental, cognitive and behavioural problems in singletons and the conclusion that PGS is associated with altered neurodevelopmental outcome in twins. WIDER IMPLICATIONS OF THE FINDINGS: The need for careful long-term monitoring of children born following embryo biopsy remains, as it is still applied in the form of PGD and it is still unknown whether embryo biopsy affects long-term neurodevelopmental outcome.

Association between C-reactive protein levels and outcome in acute lung injury in children.

UNLABELLED: High plasma C-reactive protein (CRP) levels are associated with favorable outcome in adults with acute lung injury (ALI). The association between CRP levels and outcome has not been studied in ALI in children. We performed a historical cohort study in 93 mechanically ventilated children (0-18 years) with ALI. The CRP level within 48 h of disease onset was tested for association with 28-day mortality and ventilator-free days (VFD). Clinical parameters and ventilator settings were evaluated for possible confounding. Fourteen patients died within 28 days. The median (interquartile range) CRP level in nonsurvivors was 126 mg/L (64; 187) compared with 56 mg/L (20; 105) in survivors (p = 0.01). For every 10-mg/L rise in CRP level, the unadjusted odds (95% confidence interval (95% CI)) for mortality increased 8.7% (2.1-15.8%). Cardiovascular organ failure at onset of ALI was the strongest predictor for mortality (odds ratio, 30.5 (6.2-152.5)). After adjustment for cardiovascular organ failure, for every 10-mg/L rise in CRP level, the OR (95% CI) for mortality increased 4.7% (-2.7-12.6%; p = 0.22). Increased CRP levels were associated with a decrease in VFD (ρ = -0.26, p = 0.01). CONCLUSION: increased plasma CRP levels are not associated with favorable outcome in ALI in children. This is in contrast with findings in adults with ALI.
