High-throughput Proteomics Identifies THEMIS2 as Independent Biomarker of Treatment-free Survival in Untreated CLL. Hemasphere 2023; 7:e951. [PMID: 37731707 PMCID: PMC10508458 DOI: 10.1097/hs9.0000000000000951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 07/31/2023] [Indexed: 09/22/2023] Open
Abstract
It remains challenging in chronic lymphocytic leukemia (CLL) to distinguish between patients with favorable and unfavorable time-to-first treatment (TTFT). Additionally, the downstream protein correlates of well-known molecular features of CLL are not always clear. To address this, we selected 40 CLL patients with TTFT ≤24 months and compared their B cell intracellular protein expression with 40 age- and sex-matched CLL patients with TTFT >24 months using mass spectrometry. In total, 3268 proteins were quantified in the cohort. Immunoglobulin heavy-chain variable (IGHV) mutational status and trisomy 12 were most impactful on the CLL proteome. Comparing cases to controls, 5 proteins were significantly upregulated, whereas 3 proteins were significantly downregulated. Of these, only THEMIS2, a signaling protein acting downstream of the B cell receptor, was significantly associated with TTFT, independently of IGHV and TP53 mutational status (hazard ratio, 2.49 [95% confidence interval, 1.62-3.84]; P < 0.001). This association was validated on the mRNA and protein level by quantitative polymerase chain reaction and ELISA, respectively. Analysis of 2 independently generated RNA sequencing and mass spectrometry datasets confirmed the association between THEMIS2 expression and clinical outcome. In conclusion, we present a comprehensive characterization of the proteome of untreated CLL and identify THEMIS2 expression as a putative biomarker of TTFT.

Abstract
PURPOSE The applicability of FLT3-internal tandem duplications (FLT3-ITD) for assessing measurable residual disease (MRD) in acute myeloid leukemia (AML) in complete remission (CR) has been hampered by patient-specific duplications and potential instability of FLT3-ITD during relapse. Here, we comprehensively investigated the impact of next-generation sequencing (NGS)-based FLT3-ITD MRD detection on treatment outcome in a cohort of patients with newly diagnosed AML in relation to established prognostic factors at diagnosis and other MRD measurements, ie, mutant NPM1 and multiparameter flow cytometry. METHODS In 161 patients with de novo FLT3-ITD AML, NGS was performed at diagnosis and in CR after intensive remission induction treatment. FLT3-ITD MRD status was correlated with the cumulative incidence of relapse and overall survival (OS). RESULTS NGS-based FLT3-ITD MRD was present in 47 of 161 (29%) patients with AML. Presence of FLT3-ITD MRD was associated with increased risk of relapse (4-year cumulative incidence of relapse, 75% FLT3-ITD MRD v 33% no FLT3-ITD MRD; P < .001) and inferior OS (4-year OS, 31% FLT3-ITD MRD v 57% no FLT3-ITD MRD; P < .001). In multivariate analysis, detection of FLT3-ITD MRD in CR confers independent prognostic significance for relapse (hazard ratio, 3.55; P < .001) and OS (hazard ratio 2.51; P = .002). Strikingly, FLT3-ITD MRD exceeds the prognostic value of most generally accepted clinical and molecular prognostic factors, including the FLT3-ITD allelic ratio at diagnosis and MRD assessment by NGS-based mutant NPM1 detection or multiparameter flow cytometry. CONCLUSION NGS-based detection of FLT3-ITD MRD in CR identifies patients with AML with profound risk of relapse and death that outcompetes the significance of most established prognostic factors at diagnosis and during therapy, and furnishes support for FLT3-ITD as a clinically relevant biomarker for dynamic disease risk assessment in AML.

Molecular characterization of mutant TP53 acute myeloid leukemia and high-risk myelodysplastic syndrome. Blood 2022; 139:2347-2354. [PMID: 35108372 PMCID: PMC11022827 DOI: 10.1182/blood.2021014472] [Citation(s) in RCA: 115] [Impact Index Per Article: 57.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 01/19/2022] [Indexed: 11/20/2022] Open
Abstract
Substantial heterogeneity within mutant TP53 acute myeloid leukemia (AML) and myelodysplastic syndrome with excess of blast (MDS-EB) precludes the exact assessment of prognostic impact for individual patients. We performed in-depth clinical and molecular analysis of mutant TP53 AML and MDS-EB to dissect the molecular characteristics in detail and determine its impact on survival. We performed next-generation sequencing on 2200 AML/MDS-EB specimens and assessed the TP53 mutant allelic status (mono- or bi-allelic), the number of TP53 mutations, mutant TP53 clone size, concurrent mutations, cytogenetics, and mutant TP53 molecular minimal residual disease and studied the associations of these characteristics with overall survival. TP53 mutations were detected in 230 (10.5%) patients with AML/MDS-EB with a median variant allele frequency of 47%. Bi-allelic mutant TP53 status was observed in 174 (76%) patients. Multiple TP53 mutations were found in 49 (21%) patients. Concurrent mutations were detected in 113 (49%) patients. No significant difference in any of the aforementioned molecular characteristics of mutant TP53 was detected between AML and MDS-EB. Patients with mutant TP53 have a poor outcome (2-year overall survival, 12.8%); however, no survival difference between AML and MDS-EB was observed. Importantly, none of the molecular characteristics were significantly associated with survival in mutant TP53 AML/MDS-EB. In most patients, TP53 mutations remained detectable in complete remission by deep sequencing (73%). Detection of residual mutant TP53 was not associated with survival. Mutant TP53 AML and MDS-EB do not differ with respect to molecular characteristics and survival. Therefore, mutant TP53 AML/MDS-EB should be considered a distinct molecular disease entity.

Constructing evidence-based clinical intrapartum care algorithms for decision-support tools. BJOG 2022. [PMID: 35411684 DOI: 10.1111/1471-0528.16958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 08/31/2021] [Accepted: 09/17/2021] [Indexed: 11/29/2022]
Abstract
AIM To describe standardised iterative methods used by a multidisciplinary group to develop evidence-based clinical intrapartum care algorithms for the management of uneventful and complicated labours. POPULATION Singleton, term pregnancies considered to be at low risk of developing complications at admission to the birthing facility. SETTING Health facilities in low- and middle-income countries. SEARCH STRATEGY Literature reviews were conducted to identify standardised methods for algorithm development and examples from other fields, and evidence and guidelines for intrapartum care. Searches for different algorithm topics were last updated between January and October 2020 and included a combination of terms such as 'labour', 'intrapartum', 'algorithms' and specific topic terms, using Cochrane Library and MEDLINE/PubMED, CINAHL, National Guidelines Clearinghouse and Google. CASE SCENARIOS Nine algorithm topics were identified for monitoring and management of uncomplicated labour and childbirth, identification and management of abnormalities of fetal heart rate, liquor, uterine contractions, labour progress, maternal pulse and blood pressure, temperature, urine and complicated third stage of labour. Each topic included between two and four case scenarios covering most common deviations, severity of related complications or critical clinical outcomes. CONCLUSIONS Intrapartum care algorithms provide a framework for monitoring women, and identifying and managing complications during labour and childbirth. These algorithms will support implementation of WHO recommendations and facilitate the development by stakeholders of evidence-based, up to date, paper-based or digital reminders and decision-support tools. The algorithms need to be field tested and may need to be adapted to specific contexts. TWEETABLE ABSTRACT Evidence-based intrapartum care clinical algorithms for a safe and positive childbirth experience.

Abstract
OBJECTIVES To evaluate the long-term neurodevelopmental and behavioral outcomes in surviving infants of pregnancies with spontaneous twin anemia-polycythemia sequence (TAPS), to compare outcome between donors and recipients, and to investigate potential risk factors for neurodevelopmental impairment (NDI). METHODS This was a retrospective study of a consecutive cohort of spontaneous-TAPS survivors delivered between 2005 and 2017 at the Leiden University Medical Center, The Netherlands. Neurological, motor, cognitive and behavioral development were assessed at a median age of 4 years. The primary outcome was NDI, which was a composite outcome of cerebral palsy, deafness, blindness and motor and/or cognitive delay. NDI was subdivided into two grades of severity: mild-to-moderate and severe NDI. Outcome was compared between surviving donor and recipient twins. Logistic regression analysis was used to assess risk factors for NDI. RESULTS Forty-nine twin pregnancies complicated by spontaneous TAPS were eligible for inclusion. The perinatal survival rate was 83% (81/98) of twins. Neurodevelopmental assessment was performed in 91% (74/81) of surviving twins. NDI occurred in 30% (22/74) of TAPS survivors, and was found more often in donors (44%; 15/34) than in recipients (18%; 7/40) (odds ratio (OR), 4.1; 95% CI, 1.8-9.1; P = 0.001). Severe NDI was detected in 9% (7/74) of survivors and was higher in donors compared with recipients (18% (6/34) vs 3% (1/40)), although the difference did not reach statistical significance; P = 0.056). Donors demonstrated lower cognitive scores compared with recipients (P = 0.011). Bilateral deafness was identified in 15% (5/34) of donors compared with 0% (0/40) of recipients (P = 0.056). Parental concern regarding development was reported more often for donor than for recipient twins (P = 0.001). On multivariate analysis, independent risk factors for NDI were gestational age at delivery (OR, 0.7; 95% CI, 0.5-0.9; P = 0.003) and severe anemia (OR, 6.4; 95% CI, 2.4-17.0; P < 0.001). CONCLUSION Surviving donor twins of pregnancies complicated by spontaneous TAPS have four-fold higher odds of NDI compared with recipient cotwins, are at increased risk of cognitive delay and have a high rate of deafness.

Abstract
Background Vaccination remains the mainstay of prevention of hepatitis B virus (HBV) including birth dose and hepatitis B immunoglobulins (HBIGs). National estimates of vaccination coverage exclude migrants. The objective of this study is to investigate documentation practices of HBV-related infant vaccinations in Northern Thailand including migrants. Methods This is a retrospective review of hospital records of women who birthed infants in 2015 at Maharaj Nakorn Hospital, Chiang Mai (CM) or on the Thailand-Myanmar border, Tak. Results Of 2522 women, 987 were from CM (861 Thai nationals, 126 migrants) and 1535 were from Tak (651 Thai residence and 884 Myanmar residence). In CM, documentation for the birth dose vaccine (999 of 999, 100%) and HBIG was complete. In Tak, documentation was 1441 of 1549 (93%) for birth dose and 26 of 34 (76.5%) for HBIG, with missed opportunities including home delivery, delay in obtaining hepatitis B e-antigen status, and limitations of the records. Expanded Program of Immunization (EPI) documentation of 3 follow-up vaccinations dwindled with subsequent doses and distance, and complete documentation of 3 HBV EPI vaccines at the hospital of birth was low, 41.5% (1056 of 2547), but equitable for Thai or migrant status. Conclusions This review provides strong support for excellent documentation of HBIG and birth dose vaccination in urban and rural settings, and in migrants, consistent with Thailand's vaccination policy and practice. Documentation of the 3 HBV EPI at the hospital of birth decreases with sequential doses, especially in families further away. Innovative data linkage is required to prove coverage and identify gaps.

Abstract
Multimorbidity, the simultaneous presence of multiple health conditions in an individual, is an increasingly common phenomenon globally. The systematic assessment of the quality of care delivered to people with multimorbidity will be key to informing the organization of services for meeting their complex needs. Yet, current assessments tend to focus on single conditions and do not capture the complex processes that are required for providing care for people with multimorbidity. We conducted a scoping review on quality of care and multimorbidity in selected databases in June 2018 and identified 87 documents as eligible for review, predominantly original research and reviews from North America, Europe and Australasia and mostly frequently related to primary care settings. We synthesized data qualitatively in terms of perceived challenges, evidence and proposed metrics. Findings reveal that the association between quality of care and multimorbidity is complex and depends on the conditions involved (quality appears to be higher for those with concordant conditions, and lower in the presence of discordant conditions) and the approach used for measuring quality (quality appears to be higher in people with multimorbidity when measured using condition/drug-specific process or intermediate outcome indicators, and worse when using patient-centred reports of experiences of care). People with discordant multimorbidity may be disadvantaged by current approaches to quality assessment, particularly when they are linked to financial incentives. A better understanding of models of care that best meet the needs of this group is needed for developing appropriate quality assessment frameworks. Capturing patient preferences and values and incorporate patients' voices in the form of patient-reported experiences and outcomes of care will be critical towards the achievement of high-performing health systems that are responsive to the needs of people with multimorbidity.

MBD4 guards against methylation damage and germ line deficiency predisposes to clonal hematopoiesis and early-onset AML. Blood 2018; 132:1526-1534.

Abstract
The tendency of 5-methylcytosine (5mC) to undergo spontaneous deamination has had a major role in shaping the human genome, and this methylation damage remains the primary source of somatic mutations that accumulate with age. How 5mC deamination contributes to cancer risk in different tissues remains unclear. Genomic profiling of 3 early-onset acute myeloid leukemias (AMLs) identified germ line loss of MBD4 as an initiator of 5mC-dependent hypermutation. MBD4-deficient AMLs display a 33-fold higher mutation burden than AML generally, with >95% being C>T in the context of a CG dinucleotide. This distinctive signature was also observed in sporadic cancers that acquired biallelic mutations in MBD4 and in Mbd4 knockout mice. Sequential sampling of germ line cases demonstrated repeated expansion of blood cell progenitors with pathogenic mutations in DNMT3A, a key driver gene for both clonal hematopoiesis and AML. Our findings reveal genetic and epigenetic factors that shape the mutagenic influence of 5mC. Within blood cells, this links methylation damage to the driver landscape of clonal hematopoiesis and reveals a conserved path to leukemia. Germ line MBD4 deficiency enhances cancer susceptibility and predisposes to AML.

Abstract
Abstract
Spontaneous methylcytosine (5mC) deamination is a common source of cytosine to thymine (C>T) mutations. These mutations accumulate over time, serving as a “molecular clock” that tracks cellular age. MBD4 is a thymine glycosylase that recognises sites of 5mC deamination and initiates base excision repair.
Three patients (of whom 2 are siblings) with germline MBD4 loss of function (LOF) mutations developed acute myeloid leukemia (AML) at a young age (<35 years old). Whole exome (WES) and whole genome sequencing (WGS) showed an elevated C>T mutation rate ~33 times the average for AML. The mutations occurred nearly exclusively at CG dinucleotides. Reduced representation bisulfite sequencing showed the mutations occurred at previously methylated cytosines. The 3 AMLs had somatic C>T mutations in the same driver genes (DNMT3A and either IDH1 or IDH2), suggesting the methylation damage charts a recurrent path towards malignancy in the hematopoietic system.
MBD4 is inactivated in other cancers, although this appears to be a rare event. Nine of 10,638 cancers in the TCGA database had MBD4 LOF mutations. In a uveal melanoma and a glioblastoma multiforme, there was also loss of heterozygosity of the wild-type MBD4. These 2 cancers with MBD4 deficiency exhibit the same mutational signature, with a high C>T mutation rate at CG dinucleotides.
To verify the link between MBD4 and the 5mC damage signature, Mbd4-/- and Mbd4+/+ mouse bone marrow were cultured in semi-solid agar and WGS was performed on individual myeloid progenitor colonies. Mbd4-/- myeloid progenitor colonies displayed the same increase in C>T mutations at CG dinucleotides. This highlights the importance of MBD4 across species.
Mbd4 deficient mice offer a model system to investigate mutation acquisition and cancer pathogenesis. Work on the interaction of MBD4 with other leukaemia initiating genes is underway.

Abstract
The pharmacokinetics (PK) of amoxicillin in asphyxiated newborns undergoing moderate hypothermia were quantified using prospective data (N = 125). The population PK was described by a 2-compartment model with a priori birthweight (BW) based allometric scaling. Significant correlations were observed between clearance (Cl) and postnatal age (PNA), gestational age (GA), body temperature (TEMP), and urine output (UO). For a typical patient with GA 40 weeks, BW 3,000 g, 2 days PNA (i.e., TEMP 33.5°C), and normal UO, Cl was 0.26 L/h (interindividual variability (IIV) 41.9%) and volume of distribution of the central compartment was 0.34 L/kg (IIV of 114.6%). For this patient, Cl increased to 0.41 L/h at PNA 5 days and TEMP 37.0°C. The respective contributions of both covariates were 23% and 27%. Based on Monte Carlo simulations we recommend 50 and 75 mg/kg/24h amoxicillin in three doses for patients with GA 36-37 and 38-42 weeks, respectively.

Abstract
OBJECTIVE Since 2010 the guideline 'Guideline for perinatal policy in cases of extreme prematurity' has advised an active policy in infants born at 24 weeks gestation. We investigated how infants born at 24 and 25 weeks gestation in the first year following the implementation of the guideline had developed by the age of 2 years. DESIGN Retrospective national cohort study. METHOD The study population consisted of all surviving infants born in the Netherlands at 24 or 25 weeks gestation in the period from 1 October 2010 to 1 October 2011. At a corrected age of 2 years the children underwent a general physical and neurological examination, and their cognitive scores were determined on the 'Bayley scales of infant and toddler development' (Bayley III). Examinations took place in the 10 neonatal intensive care units (NICU's) in the Netherlands. RESULTS Of 185 extremely premature infants, 166 were admitted to a NICU. A total of 95 survived to a corrected age of 2 years; 78 (82%) children were examined. Their average cognitive score on the Bayley III scale was 88 (SD: 16). Among the children born at 24 weeks gestation, 20% had mild disabilities and 20% had moderate to severe disabilities. Among the children born at 25 weeks gestation, 17% had mild disabilities and 12% had moderate to severe disabilities. CONCLUSION Of the children born at 24 weeks gestation in the first year after the introduction of active policy in the Netherlands and surviving to 2 years of age (46%), more than half had developed without disabilities. This was comparable to children born at 25 weeks gestation. Of all children born at 24 weeks gestation, 25% survived to 2 years of age without disabilities.

Abstract
AIMS To evaluate the effectiveness of a tailored, supportive intervention strategy in influencing diabetes-related distress, health status, well-being and clinical outcomes in people with Type 2 diabetes shortly after a first acute coronary event. METHODS People with Type 2 diabetes and a recent first acute coronary event (n = 201) were randomized to the intervention group (three home visits by a diabetes nurse) or the attention control group (one telephone consultation). Outcomes were measured after discharge (baseline) and at 5 months (follow-up) using validated questionnaires for diabetes-related distress (Problem Areas in Diabetes), well-being (WHO Well-Being Index) and health status (Euroqol 5 Dimensions; Euroqol Visual Analogue Scale). ancova was used to analyse change-over-time differences between groups. RESULTS Follow-up data were available for 81 participants in the intervention group (66.0 ± 9.3 years, 76% male) and 80 in the control group (65.6 ± 9.4 years, 75% male) participants. Mean diabetes-related distress was low after hospital discharge (intervention group: 8.2 ± 10.1; control group: 9.2 ± 12.4) and did not change after 5 months (intervention group: 9.2 ± 12.4; control group: 9.0 ± 11.2). Baseline well-being was less favourable but improved significantly in the intervention group (baseline: 58.5 ± 28.0; follow-up: 65.5 ± 23.7; P = 0.005), but not in the control group (baseline: 57.5 ± 25.2; follow-up: 59.6 ± 24.4; P = 0.481). Health status also improved in the intervention group (baseline: 69.9 ± 17.3; follow-up: 76.8 ± 15.6; P < 0.001) but not in the control group (baseline: 68.6 ± 15.9; follow-up: 69.9 ± 16.7; P = 0.470). A significant group effect was found for health status (F = 7.9; P = 0.006). CONCLUSIONS Although the intervention had no effect on diabetes-related distress, this might be at least partially attributable to very low levels of diabetes-related distress at baseline. Interestingly, health status scores and well-being, which were less favourable at baseline, both improved after the tailored support intervention.

Diabetes-related distress over the course of illness: results from the Diacourse study. Diabet Med 2015; 32:1617-24.

Abstract
AIMS To investigate the relationship between diabetes duration and diabetes-related distress and to examine the impact of micro- and macrovascular complications and blood glucose-lowering treatment on this relationship. METHODS We conducted a cross-sectional study in people with Type 2 diabetes who participated in the Dutch Diacourse study (n = 590) and completed the Problem Areas in Diabetes questionnaire. Data on diabetes duration, micro- and macrovascular complications and blood glucose-lowering treatment were collected. Multiple linear regression analysis was used to investigate the association between diabetes duration and diabetes-related distress, and to examine whether complications and treatment could explain this association. RESULTS A significant linear and quadratic association between diabetes duration and diabetes-related distress was found (duration: β = 0.27, P = 0.005; duration(2): β = -0.21, P = 0.030). The association between duration and distress could be explained by microvascular complications and insulin treatment, which were both more often present in people with a longer diabetes duration, and were associated with higher levels of diabetes-related distress (β = 0.20, P < 0.001 and β = 0.16, P = 0.006 respectively). Duration, age, gender, complications and treatment together explained 13.1% of the variance in distress. CONCLUSIONS Diabetes duration was associated with diabetes-related distress. This association can be explained largely by the presence of diabetes-related microvascular complications and insulin treatment. Healthcare providers should focus on distress in people with Type 2 diabetes in different stages over the course of illness, especially when complications are present or when people are on insulin treatment. As well as diabetes duration, complications and blood glucose-lowering treatment, diabetes-related distress is likely to be influenced by many other factors.

Abstract
OBJECTIVE To assess the incidence of and risk factors for adverse long-term neurodevelopmental outcome in complicated monochorionic pregnancies treated with selective feticide at our centre between 2000 and 2011. DESIGN Observational cohort study. SETTING National referral centre for fetal therapy (Leiden University Medical Centre, the Netherlands). POPULATION Neurodevelopmental outcome was assessed in 74 long-term survivors. METHODS Children, at least 2 years of age, underwent an assessment of neurologic, motor and cognitive development using standardised psychometric tests and the parents completed a behavioural questionnaire. MAIN OUTCOME MEASURES A composite outcome termed neurodevelopmental impairment including cerebral palsy (GMFCS II-V), cognitive and/or motor test score of <70, bilateral blindness or bilateral deafness requiring amplification. RESULTS A total of 131 monochorionic pregnancies were treated with selective feticide at the Leiden University Medical Centre. Overall survival rate was 88/131 (67%). Long-term outcome was assessed in 74/88 (84%). Neurodevelopmental impairment was detected in 5/74 [6.8%, 95% confidence interval (CI), 1.1-12.5] of survivors. Overall adverse outcome, including perinatal mortality or neurodevelopmental impairment was 48/131 (36.6%). In multivariate analysis, parental educational level was associated with cognitive test scores (regression coefficient B 3.9, 95% CI 1.8-6.0). Behavioural problems were reported in 10/69 (14.5%). CONCLUSIONS Adverse long-term outcome in survivor twins of complicated monochorionic pregnancies treated with selective feticide appears to be more prevalent than in the general population. Cognitive test scores were associated with parental educational level. TWEETABLE ABSTRACT Neurodevelopmental impairment after selective feticide was detected in 5/74 (6.8%, 95% CI 1.1-12.5) of survivors.

Abstract
OBJECTIVE To estimate the incidence, risk factors, severity and outcome after perinatal asphyxia in monochorionic (MC) versus dichorionic (DC) twins. METHODS We included all consecutive near-term MC and DC twins with perinatal asphyxia admitted to our neonatal ward between 2004 and 2013 and compared the perinatal characteristics and neonatal outcome between both groups. RESULTS The incidence of perinatal asphyxia in MC and DC twin infants was 4.0 (11/272) and 4.0% (8/200; p = 1.00). In contrast to DC twins, asphyxia in MC twins was strongly associated with acute exsanguination and anemia at birth; 64% (7/11) in MC twins and 0% (0/8) in DC twins (p < 0.01). Median hemoglobin level at birth in the MC and DC groups was 11.5 and 18.6 g/dl, respectively (p < 0.01). CONCLUSIONS Perinatal asphyxia in MC twins is often associated with severe anemia at birth due to acute hemorrhage through the placental vascular anastomoses.

Abstract
BACKGROUND The population of ageing people with mild and moderate intellectual disabilities (ID) is growing rapidly. This study examines how personal resources (physical health, mental health and social networks) impact the well-being of ageing people with ID. METHODS Longitudinal survey data on 667 people with a mild or moderate ID were acquired via interviews in 2006 and 2010. Indicators of personal resources (physical health, mental health and social networks) were assessed, as were indicators of well-being (satisfaction with life, happiness and loneliness). Additionally, data on background characteristics and autonomy were gathered. RESULTS The results show that age is positively related to decreased mobility and auditory disabilities and negatively related to independent living, autonomy in how one spends one's leisure time and autonomy in decision-making. Longitudinal analyses demonstrated that, with the exception of health that deteriorated, and social satisfaction that improved, almost all variables remained stable over the 4-year period. Further, good physical health in 2006 predicted happiness in 2010. CONCLUSION Despite the fact that age is associated with poorer physical and mental health and a smaller social network, this study showed that older people with ID have relatively high levels of well-being. Findings are discussed in the light of coping with ageing and impact of life events.

Abstract
BACKGROUND The prevalence of diabetes is relatively high in people with intellectual disability (ID). However, little is known about how people with ID experience having diabetes and how they manage the condition. METHOD Seventeen people with mild to moderate ID who have diabetes were interviewed. A framework on illness perceptions having an influence on diabetes self-management was used as a basis for the interviews and for the qualitative analysis. RESULTS Diabetes is associated with feelings of loss with regard to food intake and choices, and with being controlled. Most respondents did not feel ill. Information about diabetes for people with ID is lacking, but they do have questions. Family members with diabetes often serve as a role model. Diabetes self-management is impeded by a lack of information, motivation and support, few opportunities for learning, and by health factors, mood and living accommodation. Communication between health professionals and people with ID about diabetes rarely takes place. CONCLUSIONS Developing diabetes information together with the people concerned is an important step towards engagement in self-management activities. At the same time, the professional staff in living arrangements should stimulate and support the development of self-management skills in people with diabetes, by providing opportunities to learn and develop. Therefore, the professional staff also need skills and information to be able to support people with ID in building the skills and confidence they need to lead active and fulfilling lives, despite having diabetes.

Abstract
BACKGROUND Ventilator-induced lung injury has been recognized as a major contributing factor for bronchopulmonary dysplasia (BPD) in preterm infants. In the last decade, focus has shifted towards a more gentle respiratory approach. AIM To evaluate whether guideline changes in respiratory management in the delivery room and the unit improved the incidence of BPD in very preterm infants. METHODS Three cohorts of infants <30 weeks of gestation, born at the Leiden University Medical Center in the Netherlands in 1996-1997 (cohort '96), 2003-2004 (cohort '03) and 2008-2009 (cohort '08), were compared retrospectively. The major change was increasing use of continuous positive airway pressure in time, and monitoring the tidal volume during mechanical ventilation in cohort '08. The primary outcome was BPD at 36 weeks. RESULTS The incidence of BPD did not change from 47% in cohort '96 to 55% in cohort '03 (n.s.), but decreased significantly to 37% in cohort '08 (cohort '96 vs. '08 and cohort '03 vs. '08: p < 0.01). We observed the same effect when only moderate and severe BPD were counted with 27% in cohort '96, 31% in cohort '03 and 14% in '08 (cohort '96 vs. '03: p = n.s., cohort '96 vs. '08: p < 0.01, cohort '03 vs. '08: p < 0.05). The mortality rate was not significantly different between the three cohorts. CONCLUSION The incidence of BPD in our cohort of preterm infants has decreased during the last decade and could be due to the changes in respiratory management.

Abstract
BACKGROUND congenital infections are associated with a wide variety of clinical symptoms, including small for gestational age (SGA). AIMS to determine the co-occurrence of SGA and congenital TORCH infections, as diagnosed by TORCH serologic tests and/or cytomegalovirus (CMV) urine culture. STUDY DESIGN we performed a retrospective study of all neonates admitted to our neonatal intensive care unit from January 2004 to February 2010 in whom SGA was diagnosed and TORCH serologic tests and/or CMV urine cultures were performed. RESULTS TORCH serologic tests (in neonatal or maternal serum) and/or a CMV urine culture were performed in 112 neonates with SGA. None of the neonates tested positive for Toxoplasma gondii, Rubella, and Herpes simplex virus. Positive CMV urine culture was detected in 2% (2/112) of neonates, but their CMV IgM titers were negative. CONCLUSIONS the co-occurrence of TORCH congenital infection in infants with SGA is rare. Routine TORCH screening in neonates with isolated SGA does not seem warranted and should be limited to CMV urine cultures.

Abstract
OBJECTIVE To compare the effect of induction of labour with a policy of expectant monitoring for intrauterine growth restriction near term. DESIGN Multicentre randomised equivalence trial (the Disproportionate Intrauterine Growth Intervention Trial At Term (DIGITAT)). SETTING Eight academic and 44 non-academic hospitals in the Netherlands between November 2004 and November 2008. PARTICIPANTS Pregnant women who had a singleton pregnancy beyond 36+0 weeks' gestation with suspected intrauterine growth restriction. INTERVENTIONS Induction of labour or expectant monitoring. MAIN OUTCOME MEASURES The primary outcome was a composite measure of adverse neonatal outcome, defined as death before hospital discharge, five minute Apgar score of less than 7, umbilical artery pH of less than 7.05, or admission to the intensive care unit. Operative delivery (vaginal instrumental delivery or caesarean section) was a secondary outcome. Analysis was by intention to treat, with confidence intervals calculated for the differences in percentages or means. RESULTS 321 pregnant women were randomly allocated to induction and 329 to expectant monitoring. Induction group infants were delivered 10 days earlier (mean difference -9.9 days, 95% CI -11.3 to -8.6) and weighed 130 g less (mean difference -130 g, 95% CI -188 g to -71 g) than babies in the expectant monitoring group. A total of 17 (5.3%) infants in the induction group experienced the composite adverse neonatal outcome, compared with 20 (6.1%) in the expectant monitoring group (difference -0.8%, 95% CI -4.3% to 3.2%). Caesarean sections were performed on 45 (14.0%) mothers in the induction group and 45 (13.7%) in the expectant monitoring group (difference 0.3%, 95% CI -5.0% to 5.6%). CONCLUSIONS In women with suspected intrauterine growth restriction at term, we found no important differences in adverse outcomes between induction of labour and expectant monitoring. Patients who are keen on non-intervention can safely choose expectant management with intensive maternal and fetal monitoring; however, it is rational to choose induction to prevent possible neonatal morbidity and stillbirth.

Abstract
OBJECTIVE To compare the stressors accompanying chronic disease as perceived by patients and their GPs and to explore how incongruence in patients' and GPs' ideas influences patients' health status and use of health care. METHOD A total of 580 patients with a diagnosis of diabetes or osteoarthritis and their GPs were interviewed by questionnaire about the stressors accompanying a patient's illness. In addition, information was obtained from each patient on health status and use of health care. RESULTS The results show that patient and GP diverge in the way they think about chronic illness. Incongruence was larger in the case of osteoarthritis. In both diabetes and osteoarthritis, incongruence between patient and GP was associated with a worse health status of the patient and an increase in health-care use, although the pattern of correlation differed by type of disease. CONCLUSIONS A chronic disease requires an ongoing relationship between patient and GP over years. Therefore, it is especially important that providers recognize the problems with which chronic disease patients are faced. Too often, providers are one-sided focused on the medical aspects of disease, neglecting the personal impact that a chronic disease has on the patient's life. In this way, successful treatment is complicated.

Abstract
BACKGROUND In this review, we describe the growth of (very) preterm infants or (very) low-birth-weight infants from birth until adulthood. METHODS A systematic analysis of growth of these infants is thwarted by different definitions (classification by gestational age or birth weight) used in the literature. RESULTS The early postnatal period of these individuals is almost invariably characterized by substantial growth failure. In the majority of preterm infants this is followed by a period of catch-up growth, which starts in early infancy and usually stops at 2-3 years of age, although in some cases it may continue into adolescence. Catch-up growth is usually incomplete, so that infants born preterm remain shorter and lighter than term-born peers during childhood, adolescence, and adulthood. Disproportionate catch-up growth in height and weight may lead to an altered body composition in adulthood, especially in females. CONCLUSION Though early catch-up growth has shown to be beneficial for neurodevelopmental outcome, it is also associated with adverse metabolic consequences in adulthood. As the first generation of (very) preterm infants is now reaching young adulthood, future follow-up studies on these effects are warranted.

Abstract
OBJECTIVE To investigate whether postnatal allopurinol would reduce free radical induced reperfusion/reoxygenation injury of the brain in severely asphyxiated neonates. METHOD In an interim analysis of a randomised, double blind, placebo controlled study, 32 severely asphyxiated infants were given allopurinol or a vehicle within four hours of birth. RESULTS The analysis showed an unaltered (high) mortality and morbidity in the infants treated with allopurinol. CONCLUSION Allopurinol treatment started postnatally was too late to reduce the early reperfusion induced free radical surge. Allopurinol administration to the fetus with (imminent) hypoxia via the mother during labour may be more effective in reducing free radical induced post-asphyxial brain damage.

Abstract
OBJECTIVE To investigate the influence of perinatal risk factors, especially hypotension, on neuromotor status at term in surviving preterm infants born before 32 weeks of gestation. METHODS This study is part of the Leiden Follow-Up Project on Prematurity: a prospective, regional study of 266 live born infants with a gestational age (GA) < 32 weeks born in 1996-1997. Twenty-eight infants died before term age. Two hundred and eleven infants were examined neurologically at term according to Prechtl. The findings were classified as normal (N), mildly abnormal (MA) or definitely abnormal (DA). Hypotension was defined as a mean arterial blood pressure (MABP) < 30 mm Hg on at least two occasions. RESULTS One hundred and six (50%) infants were classified as neurologically N, 92 (44%) infants were classified as MA and 13 (6%) infants as DA. Hypotension, bronchopulmonary dysplasia (BPD), flaring and cystic periventricular leucomalacia (PVL) were risk factors for neurological morbidity. Of the 68 infants with hypotension, 33 (49%) were classified as MA and 7 (10%) as DA. Of the 141 infants without hypotension, 58 (41%) were MA, and 5 (4%) were DA. The odds ratio of hypotension for neurological morbidity was 1.9 (95% CI 1.06-3.40), adjusted for gestational age, birth weight, small for gestational age (SGA) and gender, it was 1.96 (95% CI 1.02-3.77). The adjusted odds ratio of PVL was 18.6 (4.4-78.5), of flaring was 2.37 (1.18-4.74) and of BPD was 2.44 (1.08-5.5). CONCLUSIONS Apart from gestational age, periventricular leucomalacia, and bronchopulmonary dysplasia, hypotension in preterm infants is a major risk factor for neurological morbidity at term.

Abstract
AIMS Diabetic patients require care from a variety of health care providers, but little is known about their actual use of health care. Aims of this study were to (1) obtain information on health care use by diabetic patients in the Netherlands, (2) distinguish patterns of health care utilisation among these patients, and (3) develop insight into the factors predicting these patterns. METHOD Data on 388 diabetic patients were extracted from a nationally representative database of patients with chronic disease. Data on health care utilisation and background variables were collected in 1998 by means of a survey. Patients' GPs registered information about medical diagnosis, illness duration and co-morbidity. Analysis included descriptive statistics, as well as cluster and logistic analysis. RESULTS Diabetic patients use a wide range of services, but large differences exist. Four patterns of health care utilisation could be distinguished: a pattern of low consumption, one of moderate consumption with a central role for internal medicine, one of more extensive diabetes care consumption, and one of high medical and home care consumption. Type 1 diabetes appeared to be an important determinant of the moderate, mainly internal medicine pattern and the more extensive diabetes care pattern. The pattern of high medical and home care was not predicted by diabetes type, but by the presence of co-morbidity and by poor self-rated health. CONCLUSION Despite the fact that diabetic patients use a wide range of health care services, there seems to be a problem of under utilisation, especially among type 2 diabetic patients.

Abstract
AIM The objective of this study was to determine behavioural outcome and risk factors for abnormal behaviour at 2 y corrected age in very premature infants in a regionally defined, prospective cohort study. METHODS The Leiden Follow-Up Project on Prematurity includes all liveborn infants of < 32 wk gestational age, born in 1996/1997 (n = 266). Behaviour was assessed with the Child Behaviour Checklist 2-3. RESULTS An analysis of 158 questionnaires of 206 survivors (77%) was carried out. Fourteen children (9%) had a total problem score > p90 ("clinical range"). This percentage is comparable with the 10% found in a sample of 2- to 3-y-olds from the Dutch general population. Univariate analysis showed higher syndrome scale scores in one or more of the Child Behaviour Checklist scales in children of lower gestational age, small for gestational age (birthweight < p10), with neurological abnormalities at term or at 2 y and of non-Dutch origin. Lower socioeconomic status and postnatal treatment with dexamethasone were associated with higher scores in the somatic problems scale and lower maternal age at birth with a higher total problem score. After correction for confounding variables, the associations between small for gestational age, neurological abnormalities at 2 y and the anxious/depressed and/or withdrawn scales remained significant. CONCLUSION The prevalence of behavioural problems at 2 y corrected age in this cohort of very premature infants (gestational age < 32 wk) was comparable with that in a general population sample. Children born small for gestational age or with neurological abnormalities at 2 y of age had higher syndrome scale scores, mainly for anxious/depressed and/or withdrawn behaviour.

Abstract
PURPOSE Previous research has highlighted disability as a determinant of the need for technical aids; surprisingly, disease as a potential determinant has been ignored. The goal of the present study was to determine whether the possession of technical aids is dependent on the type of chronic disease, illness duration, co-morbidity, disability, age, and several other factors. METHODS The study was performed in a representative sample of persons with a somatic chronic disease (n=2262). Type of chronic disease, time post-diagnosis and co-morbidity were assessed by the patient's general practitioner. Disability was assessed with the Sickness Impact Profile. The possession of technical aids and other characteristics were assessed by questionnaire. RESULTS Type of chronic disease (osteoarthritis, rheumatoid arthritis, diabetes and COPD), disability, age and gender were significantly and independently associated with the possession of technical aids. CONCLUSIONS Apart from disability, disease-, age-, and gender-related characteristics determine the possession of technical aids. A detailed assessment of these characteristics is required in order to ensure that technical aids meet personal needs.

Abstract
The aim of this study was to detect differences in depressive symptomatology in post-menopausal breast cancer patients who had recently undergone either mastectomy or breast conserving therapy. We measured depressive symptoms shortly after diagnosis and surgery as well as 6 months later. There were no significant differences in mean scores and relative risk estimates between the two treatment groups at either time of measurement. From this study we conclude that women treated by breast-conserving therapy have comparable levels of depressive symptoms to women treated by mastectomy during the first 8 months after diagnosis. Breast-conserving therapy can have cosmetic and physical advantages, but requires as much psychological adjustment as mastectomy does.

Abstract
Studies have shown that the mean scores on global subjective well-being measures of cancer patients do not differ from the mean scores of other patient samples or samples of healthy individuals. These results give rise to speculations about the nature of the concept subjective well-being. Therefore, we compared the structure of the concept subjective well-being between three groups of elderly women (cancer patients, women suffering from chronic ailments and healthy women). This was done by examining the relationships between five dimensions of subjective well-being (perceived physical health, self-esteem, negative affect, optimism and loneliness) and two measures of global subjective well-being (affective well-being and life satisfaction) in each group of women. The results clearly demonstrate the differences in the relative importance of the five dimensions for the global evaluation of well-being between the three groups. The most notable finding was that perceived physical health appears to be more strongly related to global subjective well-being, when the objective health status is worse. The unequal relative importance of dimensions of subjective well-being should be taken into account when comparing the mean scores on subjective well-being measures between populations with different states of health.

Abstract
The information-seeking behavior of cancer outpatients has been studied with the purpose of collecting data for the development of an educational intervention: stimulating communication between cancer outpatients and their specialists. The intention to seek information, the realization of the intention and the reasons for not realizing it are measured with several qualitative and quantitative methods: written questionnaires (n = 60, n = 18), audio records (n = 40) and focus group interviews (n = 19). Not every patient (58%) intends to discuss topics of illness and treatment with the specialist. Possible incentives to plan a discussion with the specialist are experienced uncertainty, fear and dissatisfaction with information received. In 22% of cases cancer outpatients do not realize their intention, and in 25% of cases the realization of the intention is due to the initiative of the specialist or the patient's companion. The information-seeking behavior of cancer outpatients appears to be influenced by several factors, including patients' needs, values and beliefs; unexpected situations; patients' skills; and specialists' and companions' behavior.

Is it correct to correct? Developmental milestones in 555 "normal" preterm infants compared with term infants. J Pediatr 1991; 118:399-404.

Abstract
To determine whether correction for preterm birth should be applied during developmental assessment, we conducted a prospective national survey of very premature infants (born at less than 32 weeks of gestation); neurodevelopment in the first 2 years was studied with the Dutch child health care developmental assessment. In 555 preterm children who had no evidence of handicap at 2 years of age, the age at which developmental milestones were reached was established. The results were compared with the results of the same assessment in Dutch children born at term. During the first year, the development of the very premature children equaled the development of normal children when full correction was applied. At 2 years of age, development was equal to or better than normal children's development without correction. We conclude that full correction for prematurity should be applied in the first year to avoid overreferral for developmental stimulation, whereas at 2 years of age correction is not necessary.
