Comparison of hypersensitivity reactions of intravenous iron: iron isomaltoside-1000 (Monofer® ) versus ferric carboxy-maltose (Ferinject® ). A single center, cohort study.

AIMS: Intravenous iron supplementation is widely used to treat iron deficiency and iron deficiency anemia when oral iron administration is ineffective or poorly tolerated. Hypersensitivity reactions (HSRs) during infusions are rare, but can be life-threatening. This study aimed to compare the risk for HSRs with the intravenous administration of iron isomaltoside-1000 and ferric carboxymaltose for the treatment of iron deficiency and iron deficiency anemia. METHODS: This was a single-centre cohort study. Nurses and physicians were instructed to fill out an HSR registration form with every administration of intravenous iron. HSRs were distinguished into serious and non-serious HSRs using the Ring and Messmer classification. RESULTS: HSRs occurred in 18/836 (2.1%) ferric carboxymaltose and 43/496 (8.7%) iron isomaltoside-1000 administrations. The crude risk for HSRs was 75% lower after ferric carboxymaltose treatment (RR = 0.248, 95% CI: 0.145-0.426, P < 0.0001). The risk for grade II HSRs was 88% lower after ferric carboxymaltoside (RR = 0.123, 95% CI: 0.051-0.294). The likelihood of HSRs was 3.4 times higher after the administration of iron isomaltoside-1000 (95% CI: 1.910-6.093, P < 0.0001). Regardless of the type of intravenous iron, patients with comorbidities have a factor 3.6 higher risk (95% CI: 1.899-6.739, P < 0.0001). CONCLUSIONS: Ferric carboxymaltose is associated with a 75% lower risk for HSRs compared with iron isomaltoside-1000 in our population. The presence of a comorbidity raises the likelihood of an HSR by a factor of three regardless of the type of intravenous iron infusion. Further research is needed to clarify the underlying mechanism in various patient groups.

Evaluating an integrated primary care approach to improve well-being among frail community-living older people: A theory-guided study protocol.

BACKGROUND: A major challenge in primary healthcare is the substantial increase in the proportion of frail community-dwelling older persons with long-term conditions and multiple complex needs. Consequently, a fundamental transformation of current models of primary care by means of implementing proactive integrated care is necessary. Therefore, an understanding of the effects of integrated primary care approaches and underlying mechanisms is essential. This article presents the design of a theory-based evaluation of an integrated primary care approach to improve well-being among frail community-living older adults, which is called "Finding and Follow-up of Frail older persons" (FFF). First, we present a theoretical model to facilitate a sound theory-guided evaluation of integrated primary care approaches for frail community-dwelling older people. The model incorporates interrelated elements of integrated primary care approaches (e.g. proactive case finding and self-management support). Efforts to improve primary care should integrate these promising components to assure productive patient-professional interactions and to improve well-being. Moreover, cognitive and behavioral components of healthcare professionals and patients are assumed to be important. Second, we present the design of the study to evaluate the FFF approach which consists of the following key components: (1) proactive case finding, (2) case management, (3) medication review, (4) self-management support, and (5) working in multidisciplinary care teams. METHODS: The longitudinal evaluation study has a matched quasi-experimental design with one pretest and one posttest (12 month follow-up) and is conducted in the Netherlands between 2014 and 2017. Both quantitative and qualitative methods are used to evaluate effectiveness, processes, and cost-effectiveness. In total, 250 frail older persons (75 years and older) of 11 GP (general practitioner) practices that implemented the FFF approach are compared with 250 frail older patients of 4 GP practices providing care as usual. In addition, data are collected from healthcare professionals. Outcome measures are based on our theoretical model. DISCUSSION: The proposed evaluation study will reveal insight into the (cost)effectiveness and underlying mechanisms of the proactive integrated primary care approach FFF. A major strength of the study is the comprehensive evaluation based on a theoretical framework. The quasi-experimental design presents some challenges.

Comprehensive Diagnostic Assessment of Health Status of Patients with Asthma or COPD: A Delphi Panel Study among Dutch Experts.

A comprehensive diagnostic assessment is needed to improve understanding of the health status of patients with chronic obstructive pulmonary disease (COPD) or asthma. Therefore, this study investigated which components and subsequent instruments should be part of a holistic assessment in secondary care. We also explored which data need to be exchanged for an adequate transfer of patients between primary and secondary care, and vice versa. A cross-sectional Web-based survey was conducted among Dutch healthcare professionals using a Delphi-like procedure; these included professionals working in primary or secondary care, medical advisors of health insurance companies and patients' representatives. The national guidelines were used as a starting point, resulting in a questionnaire addressing 55 components related to a comprehensive diagnostic assessment, covering the domains physiological impairments, symptoms, functional limitations and quality of life. Of the 151 experts and stakeholders invited, 92 (60.9%) completed the first round and 79 (52.3%) the second round; most respondents were pulmonologists. There was a high level of agreement between respondents from primary versus secondary care regarding which components should be measured during a comprehensive assessment of patients with asthma or COPD in secondary care and the instruments to measure these components. Regarding the exchange of information, upon referral, pulmonologists required little information from the general practitioners, whereas general practitioners required more extensive information after referral. An overview is provided of what should be part of a holistic assessment of health status in asthma and COPD. This information can be used as input for integrated care pathways.

Effect of a Single Dose of Vitamin D3 on Postprandial Arterial Stiffness and Inflammation in Vitamin D-Deficient Women.

CONTEXT: Cholecalciferol (vitamin D3) improves vascular function and inflammation, potentially providing an explanation for the proposed cardiovascular protection of vitamin D. OBJECTIVE: We investigated whether cholecalciferol supplementation reduces postprandial arterial dysfunction and inflammation. DESIGN: Randomized, 1:1, double-blind trial. SETTING: Diabetes and Vascular Center, Franciscus Gasthuis, Rotterdam, The Netherlands. PATIENTS: Twenty-four healthy, premenopausal, overweight or obese, vitamin D-deficient women. INTERVENTIONS: A single high (300,000 IU) or low dose (75,000 IU) of cholecalciferol. MAIN OUTCOME MEASURES: The effect of low- and high-dose cholecalciferol on postprandial leukocyte activation markers, pulse wave velocity (PWV), and augmentation index (AIx) during an oral fat loading test, expressed as area under the curve (AUC). RESULTS: High- and low-dose supplementation increased vitamin D by 163% ± 134% (P < 0.001) and 66% ± 59% (P < 0.001), respectively. Monocyte CD11b-AUC slightly increased after low but not high dose (6% ± 2%, P = 0.012, and 4% ± 1%, P = 0.339, respectively). There were no significant effects on postprandial PWV or AIx by high- or low-dose vitamin D. Fasting complement component 3 (C3) levels decreased by 5.9% (P = 0.004) in the high-dose group and by 4.0% (P = 0.018) in the low-dose group. CONCLUSION: A single dose of vitamin D does not seem to reduce arterial stiffness and leukocyte activation in overweight, vitamin D-deficient women. Vitamin D may decrease fasting C3. Possibly, higher vitamin D concentrations may be needed to decrease inflammation and improve vascular function in overweight or obese vitamin D-deficient women.

Uterine artery embolization vs hysterectomy in the treatment of symptomatic uterine fibroids: 10-year outcomes from the randomized EMMY trial.

BACKGROUND: Since 1995 uterine artery embolization has been described as an alternative for hysterectomy in patients with symptomatic fibroids. Many studies including several randomized controlled trials established uterine artery embolization as a valuable treatment. These randomized controlled trials reported outcomes in terms of health-related quality of life, clinical outcomes, efficacy, and cost-effectiveness after 1, 2, and 5 years of follow-up. OBJECTIVE: The purpose of this study was to compare clinical outcome and health-related quality of life 10 years after uterine artery embolization or hysterectomy in the treatment of heavy menstrual bleeding caused by uterine fibroids in a randomized controlled trial. STUDY DESIGN: In all, 28 Dutch hospitals recruited patients with symptomatic uterine fibroids who were eligible for hysterectomy. Patients were 1:1 randomly assigned to uterine artery embolization or hysterectomy. The outcomes assessed at 10 years postintervention were reintervention rates, health-related quality of life, and patient satisfaction, which were obtained through validated questionnaires. Study outcomes were analyzed according to original treatment assignment (intention to treat). RESULTS: A total of 177 patients were randomized from 2002 through 2004. Eventually 81 uterine artery embolization and 75 hysterectomy patients underwent the allocated treatment shortly after randomization. The remaining patients withdrew from the trial. The 10-year questionnaire was mailed when the last included patient had been treated 10 years earlier. The mean duration of follow-up was 133 months (SD 8.58) accompanied by a mean age of 57 years (SD 4.53). Questionnaires were received from 131 of 156 patients (84%). Ten years after treatment, 5 patients underwent secondary hysterectomy resulting in a total of 28 of 81 (35%) (24/77 [31%] after successful uterine artery embolization). Secondary hysterectomies were performed for persisting symptoms in all cases but 1 (for prolapse). After the initial treatment health-related quality of life improved significantly. After 10 years, generic health-related quality of life remained stable, without differences between both groups. The urogenital distress inventory and the defecation distress inventory showed a decrease in both groups, probably related to increasing age, without significant differences between study arms. Satisfaction in both groups remained comparable. The majority of patients declared being (very) satisfied about the received treatment: 78% of the uterine artery embolization group vs 87% in the hysterectomy group. CONCLUSION: In about two thirds of uterine artery embolization-treated patients with symptomatic uterine fibroids a hysterectomy can be avoided. Health-related quality of life 10 years after uterine artery embolization or hysterectomy remained comparably stable. Uterine artery embolization is a well-documented and less invasive alternative to hysterectomy for symptomatic uterine fibroids on which eligible patients should be counseled.

Feasibility and reliability of a newly developed antenatal risk score card in routine care.

OBJECTIVE: to study in routine care the feasibility and inter-rater reliability of the Rotterdam Reproductive Risk Reduction risk score card (R4U), a new semi-quantitative score card for use during the antenatal booking visit. The R4U covers clinical and non-clinical psychosocial factors and identifies overall high risk pregnancies, qualifying for intensified antenatal care. DESIGN: a population-based cross-sectional study (feasibility) and a cohort study (inter-rater reliability). SETTING: feasibility was studied in six midwifery practices and two hospitals; the reliability study was performed in one midwifery practice. PARTICIPANTS: 1096 pregnant women in the feasibility study and a subsample of 133 participants in the inter-rater reliability study. MEASUREMENTS: feasibility was expressed as (a) time needed to complete the R4U and (b) the missing rate at the item and client level. For inter-rater reliability (IRR) an independent, blinded, caregiver completed a re-test R4U during a second visit; inter-rater agreement for each item and all domain sum scores were computed. FINDINGS: completion of the R4U took 5 minutes or less in 63%; and between 5 and 10 minutes in another 33%. On the participant level 0.2% of women had >20% missing values (below 4% threshold, P<0.001). One of 77 items had a >10% missing rate. The per item IRR was 100% in 20% of the items, and below the predefined 80% threshold in 13% of the items (n=9). The domain sum scores universally differed less than the predetermined ±15% margin. KEY CONCLUSION: the R4U risk score card is a feasible and reliable instrument. IMPLICATION FOR PRACTICE: the R4U is suitable for the assessment of clinical and non-clinical risks during the antenatal booking visit in a heterogeneous urban setting in routine practice.

Selenite supplementation in euthyroid subjects with thyroid peroxidase antibodies.

CONTEXT: Euthyroid thyroid peroxidase (TPO-Ab)-positive subjects are at risk for progression to subclinical and overt autoimmune hypothyroidism. Previous studies have shown a decrease in TPO-Ab and improvement of quality-of-life (QoL) in L-T4-treated hypothyroid patients upon selenium supplementation. OBJECTIVES: To evaluate in euthyroid TPO-Ab-positive women without thyroid medication whether selenite decreases TPO-Ab and improves QoL. DESIGN: Randomized, placebo-controlled, double-blind study. PATIENTS AND METHODS: Euthyroid (TSH 0·5-5·0 mU/l, FT4 10-23 pm) women with TPO-Ab ≥ 100 kU/l were randomized to receive 200 mcg sodium selenite daily (n = 30) or placebo (n = 31) for 6 months. TSH, FT4, TPO-Ab, selenium (Se), selenoprotein P (SePP) and QoL were measured at baseline, 3, 6 and 9 months. RESULTS: There were no differences in baseline characteristics between the Se group and the placebo group. During selenite supplementation, serum Se and SePP did not change in the placebo group, but increased in the Se group. TPO-Ab and TSH did not change significantly in any group. TPO-Ab in the Se group were 895 (130-6800) at baseline, 1360 (60-7050) kU/l at 6 months, in the placebo group 1090 (120-9200) and 1130 (80-9900) kU/l, respectively (median values with range). TSH in the Se group was 2·1 (0·5-4·3) at baseline, 1·7 (0·0-5·3) mU/l at 6 months, in the placebo group 2·4 (0·7-4·4) and 2·5 (0·2-4·3) mU/l, respectively. QoL was not different between the groups. CONCLUSION: Six months selenite supplementation increased markers of selenium status but had no effect on serum TPO-Ab, TSH or quality-of-life in euthyroid TPO-Ab-positive women.

Uterine artery embolization vs hysterectomy in the treatment of symptomatic uterine fibroids: 5-year outcome from the randomized EMMY trial.

OBJECTIVE: The purpose of this study was to compare clinical outcome and health related quality of life (HRQOL) 5 years after uterine artery embolization (UAE) or hysterectomy in the treatment of menorrhagia caused by uterine fibroids. STUDY DESIGN: Patients with symptomatic uterine fibroids who were eligible for hysterectomy were assigned randomly 1:1 to hysterectomy or UAE. Endpoints after 5 years were reintervention rates, menorrhagia, and HRQOL measures that were assessed by validated questionnaires. RESULTS: Patients were assigned randomly to UAE (n = 88) or hysterectomy (n = 89). Five years after treatment 23 of 81 UAE patients (28.4%) had undergone a hysterectomy because of insufficient improvement of complaints (24.7% after successful UAE). HRQOL measures improved significantly and remained stable until the 5-year follow-up evaluation, with no differences between the groups. UAE had a positive effect both on urinary and defecation function. CONCLUSION: UAE is a well-established alternative to hysterectomy about which patients should be counseled.

Economic evaluation of uterine artery embolization versus hysterectomy in the treatment of symptomatic uterine fibroids: results from the randomized EMMY trial.

PURPOSE: To investigate whether uterine artery embolization (UAE) is a cost-effective alternative to hysterectomy for patients with symptomatic uterine fibroids, the authors performed an economic evaluation alongside the multicenter randomized EMMY (EMbolization versus hysterectoMY) trial. MATERIALS AND METHODS: Between February 2002 and February 2004, 177 patients were randomized to undergo UAE (n = 88) or hysterectomy (n = 89) and followed up until 24 months after initial treatment allocation. Conditional on the equivalence of clinical outcome, a cost minimization analysis was performed according to the intention to treat principle. Costs included health care costs inside and outside the hospital as well as costs related to absence from work (societal perspective). Cumulative standardized costs were estimated as volumes multiplied with prices. The nonparametric bootstrap method was used to quantify differences in mean (95% confidence interval [CI]) costs between the strategies. RESULTS: In total, 81 patients underwent UAE and 75 underwent hysterectomy. In the UAE group, 19 patients (23%) underwent secondary hysterectomies. The mean total costs per patient in the UAE group were significantly lower than those in the hysterectomy group ($11,626 vs $18,563; mean difference, -$6,936 [-37%], 95% CI: -$9,548, $4,281). The direct medical in-hospital costs were significantly lower in the UAE group: $6,688 vs $8,313 (mean difference, -$1,624 [-20%], 95% CI: -$2,605, -$586). Direct medical out-of-hospital and direct nonmedical costs were low in both groups (mean cost difference, $156 in favor of hysterectomy). The costs related to absence from work differed significantly between the treatment strategies in favor of UAE (mean difference, -$5,453; 95% CI: -$7,718, -$3,107). The costs of absence from work accounted for 79% of the difference in total costs. CONCLUSIONS: The 24-month cumulative cost of UAE is lower than that of hysterectomy. From a societal economic perspective, UAE is the superior treatment strategy in women with symptomatic uterine fibroids.

Symptomatic uterine fibroids: treatment with uterine artery embolization or hysterectomy--results from the randomized clinical Embolisation versus Hysterectomy (EMMY) Trial.

PURPOSE: To prospectively evaluate health-related quality of life (HRQOL) outcomes for uterine artery embolization (UAE) and hysterectomy up to 24 months after the intervention in terms of mental and physical health, urinary and defecatory function, and overall patient satisfaction. MATERIALS AND METHODS: Ethics committee approval and informed consent were obtained for the Embolisation versus Hysterectomy Trial. Women (n = 177) with uterine fibroids and heavy menstrual bleeding who were scheduled to undergo hysterectomy were randomly assigned to undergo UAE (n = 88) or hysterectomy (n = 89). HRQOL was measured six times during a 24-month follow-up period with the following validated questionnaires: Medical Outcome Study Short Form 36 (SF-36) mental component summary (MCS) and physical component summary (PCS), Health Utilities Index Mark 3, EuroQol 5D, urogenital distress inventory (UDI), incontinence impact questionnaire, and defecation distress inventory (DDI). Satisfaction was assessed with a seven-point Likert scale. Repeated measurement analysis was performed for between-group analysis. Paired t tests were performed for within-group analysis. Satisfaction was analyzed with the Fisher exact test. RESULTS: The SF-36 MCS and PCS, Health Utilities Index Mark 3, EuroQol 5D, and UDI scores were improved significantly in both groups at 6 months and afterward (P < .05). The DDI score was improved significantly in only the UAE group at 6 months and afterward (P < .05). No differences between groups were observed, with the exception of PCS scores at 6-week follow-up: Patients in the UAE group had significantly better scores than did patients in the hysterectomy group (P < .001). Improvement in PCS score at 24-month follow-up was significantly higher for patients who were employed at baseline (P = .035). At 24-month follow-up, patients in the hysterectomy group were significantly more satisfied than those in the UAE group (P = .02). CONCLUSION: Both UAE and hysterectomy improved HRQOL. No differences were observed between groups regarding HRQOL at 24-month follow-up. On the basis of HRQOL results, the authors determined that UAE is a good alternative to hysterectomy.

Dutch women's decision-making in pregnancy and labour as seen through the eyes of their midwives.

OBJECTIVE: a national study of midwives' perceptions of women's decision-making in the technical interventions in the birth process. DESIGN: questionnaire survey of women and their midwives. Midwives completed a maternity record for each woman in the study after the birth, and the women completed a demographic questionnaire at to 20-24 weeks gestation. SETTING: a stratified sample of 25 Dutch midwifery practices based on rural or urban location. Each of these 25 independent practices agreed to approach 25 eligible consecutive pregnant women on a randomly assigned day. PARTICIPANTS: in total 637 women were invited and 625 participated (response rate 98%). FINDINGS AND KEY CONCLUSIONS: midwives reported that they had a large influence in the decision to refer a woman to an obstetrician, but far and far less so when it comes to decisions around taking pharmaceutical pain relief. Midwives felt women had least say in the decision around augmentation of labour and most in the decision to sweep the membranes, whilst obstetricians had most input in the decision around primary induction of labour and least in the decision to refer from primary to secondary care. Our analysis indicated that midwives saw younger women (29 and younger) as having more influence in the decision-making process than old ones. Our analysis suggests there might be a tension between midwives own professional ideology and their non-interventionist focus and women's choice, which leads to an increase in medicalisation of childbirth.
