Hemodynamic Insights into Combined Fractional Flow Reserve and Instantaneous Wave-Free Ratio Assessment Through Quantitative [15O]H2O PET Myocardial Perfusion Imaging.

In patients evaluated for obstructive coronary artery disease (CAD), guidelines recommend using either fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) to guide coronary revascularization decision-making. The hemodynamic significance of lesions with discordant FFR and iFR measurements is debated. This study compared [15O]H2O PET-derived absolute myocardial perfusion between vessels with concordant and discordant FFR and iFR measurements. Methods: We included 197 patients suspected of obstructive CAD who had undergone [15O]H2O PET perfusion imaging and combined FFR/iFR interrogation in 468 vessels. Resting myocardial blood flow (MBF), hyperemic MBF, and coronary flow reserve (CFR) were compared among 4 groups: FFR low/iFR low (n = 79), FFR high/iFR low (n = 22), FFR low/iFR high (n = 22), and FFR high/iFR high (n = 345). Predefined [15O]H2O PET thresholds for ischemia were 2.3 mL·min-1·g-1 or less for hyperemic MBF and 2.5 or less for CFR. Results: Hyperemic MBF was lower in the concordant low (2.09 ± 0.67 mL·min-1·g-1), FFR high/iFR low (2.41 ± 0.80 mL·min-1·g-1), and FFR low/iFR high (2.40 ± 0.69 mL·min-1·g-1) groups compared with the concordant high group (2.91 ± 0.84 mL·min-1·g-1) (P < 0.001, P = 0.004, and P < 0.001, respectively). A lower CFR was observed in the concordant low (2.37 ± 0.76) and FFR high/iFR low (2.64 ± 0.84) groups compared with the concordant high group (3.35 ± 1.07, P < 0.01 for both). However, for vessels with either low FFR or low iFR, quantitative hyperemic MBF and CFR values exceeded the ischemic threshold in 38% and 49%, respectively. In addition, resting MBF exhibited a negative correlation with iFR (P < 0.001) and was associated with FFR low/iFR high discordance compared with concordant low FFR/low iFR measurements, independent of clinical and angiographic characteristics, as well as hyperemic MBF (odds ratio [OR], 0.41; 95% CI, 0.26-0.65; P < 0.001). Conclusion: We found reduced myocardial perfusion in vessels with concordant low and discordant FFR/iFR measurements. However, FFR/iFR combinations often inaccurately classified vessels as either ischemic or nonischemic when compared with hyperemic MBF and CFR. Furthermore, a lower resting MBF was associated with a higher iFR and the occurrence of FFR low/iFR high discordance. Our study showed that although combined FFR/iFR assessment can be useful to estimate the hemodynamic significance of coronary lesions, these pressure-derived indices provide a limited approximation of [15O]H2O PET-derived quantitative myocardial perfusion as the physiologic standard of CAD severity.

Inequality of opportunity in selection procedures limits diversity in higher education: An intersectional study of Dutch selective higher education programs.

Selection for higher education (HE) programs may hinder equal opportunities for applicants and thereby reduce student diversity and representativeness. However, variables which could play a role in inequality of opportunity are often studied separately from each other. Therefore, this retrospective cohort study conducts an innovative intersectional analysis of the inequality of opportunity in admissions to selective HE programs. Using a combination of multivariable logistic regression analyses and descriptive statistics, we aimed to investigate 1) the representativeness of student populations of selective HE programs, as compared to both the applicant pool and the demographics of the age cohort; 2) the demographic background variables which are associated with an applicant's odds of admission; and 3) the intersectional acceptance rates of applicants with all, some or none of the background characteristics positively associated with odds of admission. The study focused on all selective HE programs (n = 96) in The Netherlands in 2019 and 2020, using Studielink applicant data (N = 85,839) and Statistics Netherlands microdata of ten background characteristics. The results show that student diversity in selective HE programs is limited, partly due to the widespread inequality of opportunity in the selection procedures, and partly due to self-selection. Out of all ten variables, migration background was most often (negatively) associated with the odds of receiving an offer of admission. The intersectional analyses provide detailed insight into how (dis)advantage has different effects for different groups. We therefore recommend the implementation of equitable admissions procedures which take intersectionality into account.

Cost-effectiveness of twice-weekly versus once-weekly sessions of cognitive-behavioural therapy and interpersonal psychotherapy for depression at 12 months after start of treatment: randomised controlled trial.

BACKGROUND: Cost-effective treatments are needed to reduce the burden of depression. One way to improve the cost-effectiveness of psychotherapy might be to increase session frequency, but keep the total number of sessions constant. AIM: To evaluate the cost-effectiveness of twice-weekly compared with once-weekly psychotherapy sessions after 12 months, from a societal perspective. METHOD: An economic evaluation was conducted alongside a randomised controlled trial comparing twice-weekly versus once-weekly sessions of psychotherapy (cognitive-behavioural therapy or interpersonal psychotherapy) for depression. Missing data were handled by multiple imputation. Statistical uncertainty was estimated with bootstrapping and presented with cost-effectiveness acceptability curves. RESULTS: Differences between the two groups in depressive symptoms, physical and social functioning, and quality-adjusted life-years (QALY) at 12-month follow-up were small and not statistically significant. Total societal costs in the twice-weekly session group were higher, albeit not statistically significantly so, than in the once-weekly session group (mean difference €2065, 95% CI -686 to 5146). The probability that twice-weekly sessions are cost-effective compared with once-weekly sessions was 0.40 at a ceiling ratio of €1000 per point improvement in Beck Depression Inventory-II score, 0.32 at a ceiling ratio of €50 000 per QALY gained, 0.23 at a ceiling ratio of €1000 per point improvement in physical functioning score and 0.62 at a ceiling ratio of €1000 per point improvement in social functioning score. CONCLUSIONS: Based on the current results, twice-weekly sessions of psychotherapy for depression are not cost-effective over the long term compared with once-weekly sessions.

Effectiveness of psychosomatic therapy for patients with persistent somatic symptoms: Results from the CORPUS randomised controlled trial in primary care.

OBJECTIVE: To evaluate the effectiveness of psychosomatic therapy versus care as usual in primary care for patients with persistent somatic symptoms (PSS). METHODS: We conducted a pragmatic, two-armed, randomised controlled trial among primary care patients with PSS in the Netherlands that included 39 general practices and 34 psychosomatic therapists. The intervention, psychosomatic therapy, consisted of 6-12 sessions delivered by specialised exercise- and physiotherapists. PRIMARY OUTCOME MEASURE: patient's level of functioning. SECONDARY OUTCOMES: severity of physical and psychosocial symptoms, health-related quality of life, health-related anxiety, illness behaviour and number of GP contacts. RESULTS: Compared to usual care (n = 85), the intervention group (n = 84) showed no improvement in patient's level of functioning (mean difference - 0.50 [95% CI -1.10 to 0.10]; p = .10), and improvement in health-related anxiety (mean difference - 1.93 [95% CI -3.81 to -0.04]; p = .045), over 12 months. At 5-month follow-up, we found improvement in physical functioning, somatisation, and health-related anxiety. The 12-month follow-up revealed no therapy effects. Subgroup analyses showed an overall effect in patient's level of functioning for the group with moderate PSS (mean difference - 0.91 [95% CI -1.78 to -0.03]; p = .042). In the year after the end of therapy, the number of GP contacts did not differ significantly between the two groups. CONCLUSION: We only found effects on some secondary outcome measures, and on our primary outcome measure especially in patients with moderate PSS, the psychosomatic therapy appears promising for further study. TRIAL REGISTRATION: the trial is registered in the Netherlands Trial Registry, https://trialsearch.who.int/Trial2.aspx?TrialID=NTR7356 under ID NTR7356.

The handling of missing data in trial-based economic evaluations: should data be multiply imputed prior to longitudinal linear mixed-model analyses?

INTRODUCTION: For the analysis of clinical effects, multiple imputation (MI) of missing data were shown to be unnecessary when using longitudinal linear mixed-models (LLM). It remains unclear whether this also applies to trial-based economic evaluations. Therefore, this study aimed to assess whether MI is required prior to LLM when analyzing longitudinal cost and effect data. METHODS: Two-thousand complete datasets were simulated containing five time points. Incomplete datasets were generated with 10, 25, and 50% missing data in follow-up costs and effects, assuming a Missing At Random (MAR) mechanism. Six different strategies were compared using empirical bias (EB), root-mean-squared error (RMSE), and coverage rate (CR). These strategies were: LLM alone (LLM) and MI with LLM (MI-LLM), and, as reference strategies, mean imputation with LLM (M-LLM), seemingly unrelated regression alone (SUR-CCA), MI with SUR (MI-SUR), and mean imputation with SUR (M-SUR). RESULTS: For costs and effects, LLM, MI-LLM, and MI-SUR performed better than M-LLM, SUR-CCA, and M-SUR, with smaller EBs and RMSEs as well as CRs closers to nominal levels. However, even though LLM, MI-LLM and MI-SUR performed equally well for effects, MI-LLM and MI-SUR were found to perform better than LLM for costs at 10 and 25% missing data. At 50% missing data, all strategies resulted in relatively high EBs and RMSEs for costs. CONCLUSION: LLM should be combined with MI when analyzing trial-based economic evaluation data. MI-SUR is more efficient and can also be used, but then an average intervention effect over time cannot be estimated.

It is not only competitive employment that counts: Findings from a longitudinal panel of people with severe mental illness.

OBJECTIVE: Being engaged in work and social activities is associated with a better quality of life. However, little evidence is available on the relationship between different categories of social participation and quality of life in people with severe mental illnesses. Furthermore, longitudinal studies considering this relationship in people with severe mental illnesses (SMI) are scarce. This study attempts to fill this gap by exploring whether and how different categories of social participation and quality of life were associated over a period of 4 years. METHOD: The association between social participation activities and quality of life was analyzed with linear mixed models, using data from a Dutch national panel of people with SMI. Four annual waves including self-reported measures were used. Three categories of participation were assessed: paid employment, voluntary work, outside social activities. RESULTS: From 2015 to 2018, 1.682 panel members (18-75 years old) participated in the survey. All three participation variables show a unique significant positive association with quality of life. Controlling for covariates (age, sex, and mental health) comparable regression coefficients were found: paid employment, .208, 95% CI [.090-.326], voluntary work, .210, 95% CI [.120-.300], and outside social activities, .239, 95% CI [.154-.324]. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The value of participation for people with SMI seems to be not restricted to competitive employment. Engagement in paid employment, voluntary work, and performing outside social activities each have a comparable and additional positive association with quality of life. Therefore, rehabilitation professionals should pay attention to social participation activities in a broad range. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Selection for health professions education leads to increased inequality of opportunity and decreased student diversity in The Netherlands, but lottery is no solution: A retrospective multi-cohort study.

BACKGROUND: Concerns exist about the role of selection in the lack of diversity in health professions education (HPE). In The Netherlands, the gradual transition from weighted lottery to selection allowed for investigating the variables associated with HPE admission, and whether the representativeness of HPE students has changed. METHOD: We designed a retrospective multi-cohort study using Statistics Netherlands microdata of all 16-year-olds on 1 October 2008, 2012, and 2015 (age cohorts, N > 600,000) and investigated whether they were eligible students for HPE programs (n > 62,000), had applied (n > 14,000), and were HPE students at age 19 (n > 7500). We used multivariable logistic regression to investigate which background variables were associated with becoming an HPE student. RESULTS: HPE students with ≥1 healthcare professional (HP) parent, ≥1 top-10% income/wealth parent, and women are overrepresented compared to all age cohorts. During hybrid lottery/selection (cohort-2008), applicants with ≥1 top-10% wealth parent and women had higher odds of admission. During 100% selection (cohort-2015) this remained the case. Additionally, applicants with ≥1 HP parent had higher odds, those with a migration background had lower odds. CONCLUSIONS: Odds of admission are increasingly influenced by applicants' backgrounds. Targeted recruitment and equitable admissions procedures are required to increase matriculation of underrepresented students.

One-Stop Surgery: An Innovation to Limit Hospital Visits in Children.

INTRODUCTION: One-stop surgery (OSS) allows for same-day outpatient clinic visit, preoperative assessment, and surgical repair. This study aims to determine the efficiency, (cost-)effectiveness, and family satisfaction of one-stop inguinal hernia surgery compared with usual care. MATERIAL AND METHODS: Children (≥ 3 months) with inguinal hernia and American Society of Anesthesiologists (ASA) grades I-II, scheduled for OSS (intervention) or regular treatment (control) between March 1, 2017, and December 1, 2018, were eligible for inclusion. Exclusion criteria consisted of age less than 3 months and ASA grades III-IV. The primary outcome measure was treatment efficiency (i.e., total number of hospital visits and waiting time [days] between referral and surgery). Secondary outcome measures were the effectiveness in terms of complication and recurrence rate, and parent-reported satisfaction and cost-effectiveness using the Dutch Pediatric Quality of Life Healthcare Satisfaction and Institute for Medical Technology Assessment Productivity Cost Questionnaire. RESULTS: Ninety-one (intervention: 54; control: 37) patients (56% boys) were included. Median (interquartile range) number of hospital visits was lower in the intervention group (1 vs 3; p < 0.001). All but one of the OSS patients (98%) were discharged home on the day of surgery. Postoperative complication (1.9% vs 2.7%; p = 0.787) and recurrence rates (0% vs 2.7%; p = 0.407) did not differ between the intervention and control patients. "General satisfaction," "satisfaction with communication," and "inclusion of family" were higher after OSS, while satisfaction about "information," "technical skills," and "emotional needs" were similar. Median (range) follow-up was 28 (15-36) months. CONCLUSIONS: Pediatric one-stop inguinal hernia repair seems to be an effective treatment strategy that limits the number of hospital visits and provides enhanced family satisfaction without compromising the quality of care.

Contralateral surgical exploration during inguinal hernia repair in infants (HERNIIA trial): study protocol for a multi-centre, randomised controlled trial.

BACKGROUND: The incidence of metachronous contralateral inguinal hernia (MCIH) is high in infants with an inguinal hernia (5-30%), with the highest risk in infants aged 6 months or younger. MCIH is associated with the risk of incarceration and necessitates a second operation. This might be avoided by contralateral exploration during primary surgery. However, contralateral exploration may be unnecessary, leads to additional operating time and costs and may result in additional complications of surgery and anaesthesia. Thus, there is no consensus whether contralateral exploration should be performed routinely. METHODS: The Hernia-Exploration-oR-Not-In-Infants-Analysis (HERNIIA) study is a multicentre randomised controlled trial with an economic evaluation alongside to study the (cost-)effectiveness of contralateral exploration during unilateral hernia repair. Infants aged 6 months or younger who need to undergo primary unilateral hernia repair will be randomised to contralateral exploration or no contralateral exploration (n = 378 patients). Primary endpoint is the proportion of infants that need to undergo a second operation related to inguinal hernia within 1 year after primary repair. Secondary endpoints include (a) total duration of operation(s) (including anaesthesia time) and hospital admission(s); (b) complications of anaesthesia and surgery; and (c) participants' health-related quality of life and distress and anxiety of their families, all assessed within 1 year after primary hernia repair. Statistical testing will be performed two-sided with α = .05 and according to the intention-to-treat principle. Logistic regression analysis will be performed adjusted for centre and possible confounders. The economic evaluation will be performed from a societal perspective and all relevant costs will be measured, valued and analysed. DISCUSSION: This study evaluates the effectiveness and cost-effectiveness of contralateral surgical exploration during unilateral inguinal hernia repair in children younger than 6 months with a unilateral inguinal hernia.

Sleep characteristics across the lifespan in 1.1 million people from the Netherlands, United Kingdom and United States: a systematic review and meta-analysis.

We aimed to obtain reliable reference charts for sleep duration, estimate the prevalence of sleep complaints across the lifespan and identify risk indicators of poor sleep. Studies were identified through systematic literature search in Embase, Medline and Web of Science (9 August 2019) and through personal contacts. Eligible studies had to be published between 2000 and 2017 with data on sleep assessed with questionnaires including ≥100 participants from the general population. We assembled individual participant data from 200,358 people (aged 1-100 years, 55% female) from 36 studies from the Netherlands, 471,759 people (40-69 years, 55.5% female) from the United Kingdom and 409,617 people (≥18 years, 55.8% female) from the United States. One in four people slept less than age-specific recommendations, but only 5.8% slept outside of the 'acceptable' sleep duration. Among teenagers, 51.5% reported total sleep times (TST) of less than the recommended 8-10 h and 18% report daytime sleepiness. In adults (≥18 years), poor sleep quality (13.3%) and insomnia symptoms (9.6-19.4%) were more prevalent than short sleep duration (6.5% with TST < 6 h). Insomnia symptoms were most frequent in people spending ≥9 h in bed, whereas poor sleep quality was more frequent in those spending <6 h in bed. TST was similar across countries, but insomnia symptoms were 1.5-2.9 times higher in the United States. Women (≥41 years) reported sleeping shorter times or slightly less efficiently than men, whereas with actigraphy they were estimated to sleep longer and more efficiently than man. This study provides age- and sex-specific population reference charts for sleep duration and efficiency which can help guide personalized advice on sleep length and preventive practices.

External validation of a prediction model and decision tree for sickness absence due to mental disorders.

PURPOSE: A previously developed prediction model and decision tree were externally validated for their ability to identify occupational health survey participants at increased risk of long-term sickness absence (LTSA) due to mental disorders. METHODS: The study population consisted of N = 3415 employees in mobility services who were invited in 2016 for an occupational health survey, consisting of an online questionnaire measuring the health status and working conditions, followed by a preventive consultation with an occupational health provider (OHP). The survey variables of the previously developed prediction model and decision tree were used for predicting mental LTSA (no = 0, yes = 1) at 1-year follow-up. Discrimination between survey participants with and without mental LTSA was investigated with the area under the receiver operating characteristic curve (AUC). RESULTS: A total of n = 1736 (51%) non-sick-listed employees participated in the survey and 51 (3%) of them had mental LTSA during follow-up. The prediction model discriminated (AUC = 0.700; 95% CI 0.628-0.773) between participants with and without mental LTSA during follow-up. Discrimination by the decision tree (AUC = 0.671; 95% CI 0.589-0.753) did not differ significantly (p = 0.62) from discrimination by the prediction model. CONCLUSION: At external validation, the prediction model and the decision tree both poorly identified occupational health survey participants at increased risk of mental LTSA. OHPs could use the decision tree to determine if mental LTSA risk factors should be explored in the preventive consultation which follows after completing the survey questionnaire.

Determinants of Post-acute Care Costs in Acutely Hospitalized Older Adults: The Hospital-ADL Study.

OBJECTIVES: After hospitalization, many older adults need post-acute care, including rehabilitation or home care. However, post-acute care expenses can be as high as the costs for the initial hospitalization. Detailed information on monthly post-acute health care expenditures and the characteristics of patients that make up for a large share of these expenditures is scarce. We aimed to calculate costs in acutely hospitalized older patients and identify patient characteristics that are associated with high post-acute care costs. DESIGN: Prospective multicenter cohort study (between October 2015 and June 2017). SETTING AND PARTICIPANTS: 401 acutely hospitalized older persons from internal medicine, cardiology, and geriatric wards. MEASUREMENTS: Our primary outcome was mean post-acute care costs within 90 days postdischarge. Post-acute care costs included costs for unplanned readmissions, home care, nursing home care, general practice, and rehabilitation care. Three costs categories were defined: low [0-50th percentile (p0-50)], moderate (p50-75), and high (p75-100). Multinomial logistic regression analyses were conducted to assess the associations between costs and frailty, functional impairment, health-related quality of life, cognitive impairment, and depressive symptoms. RESULTS: Costs were distributed unevenly in the population, with the top 10.0% (n = 40) accounting for 52.1% of total post-acute care costs. Mean post-acute care costs were €4035 [standard deviation (SD) 4346] or $4560 (SD 4911). Frailty [odds ratio (OR) 3.44, 95% confidence interval (CI) 1.78-6.63], functional impairment (OR 1.80, 95% CI 1.03-3.16), and poor health-related quality of life (OR 1.89, 95% CI 1.09-3.28) at admission were associated with classification in the high-cost group, compared with the low-cost group. CONCLUSIONS/IMPLICATIONS: Post-acute care costs are substantial in a small portion of hospitalized older adults. Frailty, functional impairment, and poor health-related quality of life are associated with higher post-acute care costs and may be used as an indicator of such costs in practice.

Characteristics of sports participation and psychosocial health in children: Results of a cross-sectional study.

Several studies suggest that sports participation is beneficial for psychosocial health. There is, however, only a limited number of studies about the relationship of specific characteristics of sports participation with psychosocial health. The present study investigated associations between characteristics of sports participation and three aspects of psychosocial health, i.e. internalising problems, externalising problems and prosocial behaviour. The examined characteristics of sports participation pertained to individual versus team sports, indoor versus outdoor sports, involvement in competition or not, and contact sports versus non-contact sports. Cross-sectional data were collected from 1768 Dutch children aged 10-12 years who were member of a sports club. These children completed the Movement and Sports Monitor Questionnaire Youth aged 8-12 years (MSMQ) and the Strength and Difficulties Questionnaire (SDQ). Linear multilevel analyses and logistic generalised estimating equation were conducted. Children participating in team sports, outdoor sports, or competition showed fewer internalising problems than children engaged in individual sports, indoor sports, or only training. The associations with internalising problems were stronger for boys than for girls. Children participating in non-contact sports showed fewer externalising problems than children performing non-contact sports as well as contact sports. Children practising indoor sports or non-contact sports showed better prosocial behaviour than children doing outdoor or contact sports. In conclusion, the form of sports participation seemed to matter highly with respect to internalising problems, especially for boys, and, to a lesser extent, with respect to externalising problems and prosocial behaviour. This offers starting points for developing tailor-made sports programmes for children.

Shared decision-making in mental health care using routine outcome monitoring: results of a cluster randomised-controlled trial.

PURPOSE: To investigate the effects of Shared Decision-Making (SDM) using Routine Outcome Monitoring (ROM) primary on patients' perception of Decisional Conflict (DC), which measures patients' engagement in and satisfaction with clinical decisions, and secondary on working alliance and treatment outcomes. METHOD: Multi-centre two-arm matched-paired cluster randomised-controlled trial in Dutch specialist mental health care. SDM using ROM (SDMR) was compared with Decision-Making As Usual (DMAU). Outcomes were measured at baseline (T0) and 6 months (T1). Multilevel regression and intention-to-treat analyses were used. Post hoc analyses were performed on influence of subgroups and application of SDMR on DC. RESULTS: Seven teams were randomised to each arm. T0 was completed by 186 patients (51% intervention; 49% control) and T1 by 158 patients (51% intervention, 49% control). DC, working alliance, and treatment outcomes reported by patients did not differ significantly between two arms. Post hoc analyses revealed that SDMR led to less DC among depressed patients (p = 0.047, d =- 0.69). If SDMR was applied well, patients reported less DC (SDM: p = 0.000, d = - 0.45; ROM: p = 0.021, d = - 0.32), which was associated with better treatment outcomes. CONCLUSION: Except for patients with mood disorders, we found no difference between the arms for patient-reported DC. This might be explained by the less than optimal uptake of this generic intervention, which did not support patients directly. Regarding the positive influence of a higher level of applying SDM and ROM on less DC and better treatment outcomes, the results are encouraging for further investments in patient-oriented development and implementation of SDMR.

Role of 3-Dimensional Sonography in the Assessment of Submucous Fibroids: A Pilot Study.

OBJECTIVES: To investigate the accuracy and reliability of 3-dimensional (3D) transvaginal sonography in classifying submucous fibroids using the International Federation of Gynecology and Obstetrics PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified) classification and protrusion (percent) compared to 2-dimensional (2D) transvaginal sonography, 2D saline infusion sonography, and 3D saline infusion sonography, using hysteroscopy as a reference test. METHODS: A prospective cohort pilot study was performed among 14 consecutive patients undergoing hysteroscopic surgery, preceded by routine sonography (2D transvaginal sonography, 2D saline infusion sonography, 3D transvaginal sonography, and 3D saline infusion sonography). RESULTS: The intraclass correlation coefficient (ICC) for 2D transvaginal sonography versus hysteroscopy was 0.69 (95% confidence interval [CI], 0.06, 0.90) compared to 0.94 (95% CI, 0.83, 0.98) for 2D saline infusion sonography. The ICCs for 3D transvaginal sonography versus hysteroscopy were 0.69 (95% CI, 0.03, 0.90 [investigator A]) and 0.55 (95% CI, -0.48, 0.86 [investigator B]). The ICCs for 3D saline infusion sonography versus hysteroscopy were 0.94 (95% CI, 0.81, 0.98 [investigator A]) and 0.87 (95% CI, 0.60, 0.96 [investigator B]). Interobserver agreement of 3D transvaginal sonography was 0.81 (95% CI, 0.43, 0.94) compared to 0.86 (95% CI, 0.56, 0.96) for 3D saline infusion sonography. CONCLUSIONS: In these preliminary data, 3D transvaginal sonography was not as accurate as 2D or 3D saline infusion sonography and was not more accurate than 2D transvaginal sonography. There was moderate interobserver agreement for 3D transvaginal sonography. There might be room for improvement, as 3D transvaginal sonography is more accurate when endometrial thickness increases. Further study is warranted to evaluate in which patients saline infusion sonography eventually can be obviated.

Targeting the underlying causes of undernutrition. Cost-effectiveness of a multifactorial personalized intervention in community-dwelling older adults: A randomized controlled trial.

BACKGROUND & AIMS: Undernutrition in old age is associated with increased morbidity, mortality and health care costs. Treatment by caloric supplementation results in weight gain, but compliance is poor in the long run. Few studies targeted underlying causes of undernutrition in community-dwelling older adults. This study aimed to evaluate the cost-effectiveness of a multifactorial personalized intervention focused on eliminating or managing the underlying causes of undernutrition to prevent and reduce undernutrition in comparison with usual care. METHODS: A randomized controlled trial was performed among 155 community-dwelling older adults receiving home care with or at risk of undernutrition. The intervention included a personalized action plan and 6 months support. The control group received usual care. Body weight, and secondary outcomes were measured in both groups at baseline and 6 months follow-up. Multiple imputation, linear regression and generalized estimating equation analyses were used to analyze intervention effects. In the cost-effectiveness analyses regression models were bootstrapped to estimate statistical uncertainty. RESULTS: This intervention showed no statistically significant effects on body weight, mid-upper arm circumference, grip strength, gait speed and 12-Item Short-Form Health Survey physical component scale as compared to usual care, but there was an effect on the 12-Item Short-Form Health Survey mental component scale (0-100) (ß = 8.940, p=0.001). Borderline significant intervention effects were found for both objective and subjective physical function measures, Short Physical Performance Battery (0-12) (ß = 0.56, p=0.08) and ADL-Barthel score (0-20) (ß = 0.69, p=0.09). Societal costs in the intervention group were statistically non-significantly lower than in the control group (mean difference -274; 95% CI -1111; 782). Cost-effectiveness acceptability curves showed that the probability of cost-effectiveness was 0.72 at a willingness-to-pay of 1000 €/kg weight gain and 0.80 at a willingness-to-pay of 20,000 €/quality-adjusted life year gained. CONCLUSIONS: This multifactorial personalized intervention showed a statistically non-significant effect and was not cost-effective on body-weight compared to usual care. We observed consistently beneficial treatment effects in the intervention group on all outcomes measures. CLINICAL TRIAL REGISTRY NUMBER AND WEBSITE: NTR5184 (www.trialregister.nl).

Can an early perceptuo-motor skills assessment predict future performance in youth table tennis players? An observational study (1998-2013).

This study intended to investigate the capability of the 4 test items "sprint", "agility", "speed while dribbling" and "throwing a ball" of the Dutch perceptuo-motor skills assessment used at the age of 7-10 years to predict table tennis performance (U13, U15 and U18) in an observational study. Data of 1191 young table tennis players, collected from 1998 to 2013, were analysed in univariable and multivariable logistic and linear regression models. The test items "sprint" and "throwing a ball" showed to be significant predictors for table tennis performance outcomes in boys (P < 0.05). For girls, besides these test items also "speed while dribbling" had a significant contribution (P < 0.05). Since the accuracies of the models were low, it is advised to include other determinants to enhance the predictive value of a model for table tennis performance. Nevertheless, it can be concluded that a perceptuo-motor skills assessment might improve the effectiveness of talent programmes in table tennis as an additional method to objectively estimate a youth players' potential. Future research focusing on the inclusion of test items specifically assessing eye hand coordination and other domains, for example, the psychological and the environmental domain, related to table tennis performance are recommended.

Embryo selection using time-lapse analysis (Early Embryo Viability Assessment) in conjunction with standard morphology: a prospective two-center pilot study.

STUDY QUESTION: Does prospective embryo selection using the results from the Eava Test (Early Embryo Viability Assessment) in combination with standard morphology increase the pregnancy rate of IVF and ICSI patients compared to embryo selection based on morphology only? SUMMARY ANSWER: Embryo selection using the Eeva Test plus standard morphology on Day 3 results in comparable pregnancy rates as conventional morphological embryo selection. WHAT IS KNOWN ALREADY: Time-lapse monitoring of embryo development may represent a superior way to culture and select embryos in vitro. The Eeva Test records the development of each embryo with a cell-tracking system and predicts the likelihood (High, Medium or Low) that an embryo will form a blastocyst based on an automated analysis of early cell division timings. STUDY DESIGN, SIZE, DURATION: This trial was designed as a prospective, observational, two-center pilot study with a propensity matched control group. The analysis involved 280 of 302 enrolled patients who were included in the Eeva Test group in 2013 and 560 control patients who were treated in the years 2011-2013. The majority of transfers (98%) were single embryo transfers. PARTICIPANTS/MATERIALS, SETTING, METHODS: Two academic hospitals (VUmc Amsterdam and UZ Gent) enrolled patients <41 years old, with <3 previous attempts and ≥5 normally fertilized eggs. Propensity matching was used to identify a propensity matched control group from a cohort of 1777 patients based on age, cycle number, oocyte number and number of fertilized oocytes. MAIN RESULTS AND THE ROLE OF CHANCE: There was no difference in patient baseline characteristics between the two groups. The ongoing pregnancy rate (OPR) of patients enrolled in the Eeva Test group (34.3%; 96/280) did not differ significantly from the OPR in the propensity matched control group (34.6%, 194/560; P = 0.92). However, significantly less top quality embryos (eight-cell embryos with ≤25% fragmentation) were transferred in the Eeva Test group compared to the propensity matched control group (70.4% vs. 82.3%; P < 0.001). The transfer of Eeva High and Medium embryos resulted in a significantly higher OPR of 36.8% (89/242) compared to 18.4% (7/38) for Eeva Low embryos (P = 0.02). LIMITATION, REASONS FOR CAUTION: This pilot study is limited by its nonrandomized design with a concurrent and historical control. WIDER IMPLICATIONS OF THE FINDINGS: Our pilot data did not reveal significant differences between time-lapse based and conventional embryo selection. Interestingly, the pregnancy rates were comparable in both groups even though the morphological quality of the transferred embryos was significantly lower in the Eeva Test group compared to the propensity matched control group. A sufficiently powered three-armed randomized controlled trial (RCT) with a solid design should be performed to generate decisive evidence in the future. STUDY FINDING/COMPETING INTERESTS: Progyny Inc., formerly Auxogyn provided the Eeva scopes, software and technical support for this study. The funding sources did neither influence data collection, management, analysis and interpretation of the data, nor the preparation of the manuscript.

Watchful waiting for subthreshold depression and anxiety in visually impaired older adults.

PURPOSE: Immediate treatment of depression and anxiety may not always be necessary in resilient patients. This study aimed to determine remission rates of subthreshold depression and anxiety, incidence rates of major depressive and anxiety disorders, and predictors of these remission and incidence rates in visually impaired older adults after a three-month 'watchful waiting' period. METHODS: A pretest-posttest study in 265 visually impaired older adults (mean age 74 years), from outpatient low-vision rehabilitation services, with subthreshold depression and/or anxiety was performed as part of a randomised controlled trial on the cost-effectiveness of a stepped-care intervention. An ordinal logistic regression analysis was conducted. Main outcome measures were: (1) subthreshold depression and anxiety measured with the Centre for Epidemiologic Studies Depression Scale (CES-D) and the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A), and (2) depressive and anxiety disorders measured with the Mini International Neuropsychiatric Interview. RESULTS: After a three-month watchful waiting period, depression and anxiety decreased significantly by 3.8 (CES-D) and 1.4 points (HADS-A) (p < 0.001). Of all participants, 34 % recovered from subthreshold depression and/or anxiety and 18 % developed a depressive and/or anxiety disorder. Female gender [odds ratio (OR) 0.49, 95 % confidence interval (CI) 0.28-0.86], more problems with adjustment to vision loss at baseline (OR 1.02, 95 % CI 1.00-1.03), more symptoms of depression and anxiety at baseline (OR 1.06, 95 % CI 1.02-1.10), and a history of major depressive, dysthymic, and/or panic disorder (OR 2.28, 95 % CI 1.28-4.07) were associated with lower odds of remitting from subthreshold depression and/or anxiety and higher odds of developing a disorder after watchful waiting. CONCLUSIONS: Watchful waiting can be an appropriate step in managing depression and anxiety in visually impaired older adults. However, female gender, problems with adjustment to vision loss, higher depression and anxiety symptoms, and a history of a depressive or anxiety disorder confer a disadvantage. Screening tools may be used to identify patients with these characteristics, who may benefit more from higher intensity treatment or a shorter period of watchful waiting.

Effect of tailored antibiotic stewardship programmes on the appropriateness of antibiotic prescribing in nursing homes.

OBJECTIVES: To evaluate the effect of tailored interventions on the appropriateness of decisions to prescribe or withhold antibiotics, antibiotic use and guideline-adherent antibiotic selection in nursing homes (NHs). METHODS: We conducted a quasi-experimental study in 10 NHs in the Netherlands. A participatory action research (PAR) approach was applied, with local stakeholders in charge of selecting tailored interventions based on opportunities for improved antibiotic prescribing that they derived from provided baseline data. An algorithm was used to evaluate the appropriateness of prescribing decisions, based on infections recorded by physicians. Effects of the interventions on the appropriateness of prescribing decisions were analysed with a multilevel logistic regression model. Pharmacy data were used to calculate differences in antibiotic use and recorded infections were used to calculate differences in guideline-adherent antibiotic selection. RESULTS: The appropriateness of 1059 prescribing decisions was assessed. Adjusting for pre-test differences in the proportion of appropriate prescribing decisions (intervention, 82%; control, 70%), post-test appropriateness did not differ between groups (crude: P = 0.26; adjusted for covariates: P = 0.35). We observed more appropriate prescribing decisions at the start of data collection and before receiving feedback on prescribing behaviour. No changes in antibiotic use or guideline-adherent antibiotic selection were observed in intervention NHs. CONCLUSIONS: The PAR approach, or the way PAR was applied in the study, was not effective in improving antibiotic prescribing behaviour. The study findings suggest that drawing prescribers' attention to prescribing behaviour and monitoring activities, and increasing use of diagnostic resources may be promising interventions to improve antibiotic prescribing in NHs.
