Anti-RH1 alloimmunization: At what maternal antibody threshold is there a risk of severe fetal anemia?

BACKGROUND: To define a threshold of maternal antibodies at risk of severe fetal anemia in patients followed for anti-RH1 alloimmunization (AI). STUDY, DESIGN, AND METHODS: We conducted a retrospective study of patients followed for anti-RH1 AI at the Lille University Hospital. The first group, severe anemia, included patients who received one or more in utero transfusions (IUT) or who were induced before 37 weeks of pregnancy for suspected severe fetal anemia. The second group, absence of severe anemia, corresponded to patients without intervention during pregnancy related to AI. Sensitivities, specificities, and positive and negative predictive values for screening for severe fetal anemia were calculated for the antibody thresholds of 3.5 and 5 IU/ml for the quantification. RESULTS: Between 2000 and 2018, 207 patients were included 135 in the severe anemia group and 72 in the no severe anemia group. No severe anemia was observed for an antibody titer below 16. For an antibody threshold of 3.5 IU/ml, the sensitivity was 98.2%, with 30.2% false positives. All severe anemias were detected in the second trimester; two cases of severe anemia were not detected in the third trimester. For an antibody threshold of 5 IU/ml, the sensitivity was lower at 95.6%, with five cases of severe anemia not detected. CONCLUSION: The antibody threshold of 3.5 IU/ml for the quantification and 16 for the titration allow targeting patients requiring close monitoring by an experienced team in case of anti-RH1 AI.

Relationships between Circulating Sclerostin, Bone Marrow Adiposity, Other Adipose Deposits and Lean Mass in Post-Menopausal Women.

Sclerostin is a Wnt signaling pathway inhibitor that negatively regulates bone formation. Bone-marrow-derived stromal cell (BMSC) differentiation is influenced by the Wnt pathway, leading to the hypothesis that higher levels of sclerostin might be associated with an increase in bone marrow adiposity (BMA). The main purpose of this study was to determine whether a relationship exists between circulating sclerostin and BMA in post-menopausal women with and without fragility fractures. The relationships between circulating sclerostin and body composition parameters were then examined. The outcomes measures included vertebral and hip proton density fat fraction (PDFF) using the water fat imaging (WFI) MRI method; DXA scans; and laboratory measurements, including serum sclerostin. In 199 participants, no significant correlations were found between serum sclerostin and PDFF. In both groups, serum sclerostin was correlated positively with bone mineral density (R = 0.27 to 0.56) and negatively with renal function (R = -0.22 to -0.29). Serum sclerostin correlated negatively with visceral adiposity in both groups (R = -0.24 to -0.32). Serum sclerostin correlated negatively with total body fat (R = -0.47) and appendicular lean mass (R = -0.26) in the fracture group, but not in the controls. No evidence of a relationship between serum sclerostin and BMA was found. However, serum sclerostin was negatively correlated with body composition components, such as visceral adiposity, total body fat and appendicular lean mass.

Dual-Energy CT Perfusion of Invasive Tumor Front in Non-Small Cell Lung Cancers.

Background Active endothelial cell proliferation occurs at the tumor edge, known as the invading-tumor front. This study focused on perfusion analysis of non-small cell lung cancers. Purpose To analyze dual-phase, dual-energy CT perfusion according to the degree of tumor hypoxia. Materials and Methods This prospective study was performed 2016-2017. A two-phase dual-energy CT protocol was obtained for consecutive participants with operable non-small cell lung cancer. The first pass and delayed iodine concentration within the tumor and normalized iodine uptake, corresponding to the iodine concentration within the tumor normalized to iodine concentration within the aorta, were calculated for the entire tumor and within three peripheral layers automatically segmented (ie, 2-mm-thick concentric subvolumes). The expression of the membranous carbonic anhydrase (mCA) IX, a marker of tumor hypoxia, was assessed in tumor specimens. Comparative analyses according to the histologic subtypes, type of resected tumors, and mCA IX expression were performed. Results There were 33 mCA IX-positive tumors and 16 mCA IX-negative tumors. In the entire tumor, the mean normalized iodine uptake was higher on delayed than on first-pass acquisitions (0.35 ± 0.17 vs 0.13 ± 0.15, respectively; P < .001). A single layer, located at the edge of the tumor, showed higher values of the iodine concentration (median, 0.53 mg/mL vs 0.21 mg/mL, respectively; P = .03) and normalized iodine uptake (0.04 vs 0.02, respectively; P = .03) at first pass in mCA IX-positive versus mCA IX-negative tumors. Within this layer, a functional profile of neovascularization was found in 23 of 33 (70%) of mCA IX-positive tumors, and the median mCA IX score of these tumors was higher than in tumors with a nonfunctional profile of neovascularization (median mCA IX score, 20 vs 2, respectively; P = .03). Conclusion A two-phase dual-energy CT examination depicted higher perfusion between the tumor edge and lung parenchyma in hypoxic tumors. © RSNA, 2021 Online supplemental material is available for this article.

Screening for neurodevelopmental disorders in children with congenital heart disease.

The aim of this study was to evaluate the frequency of neurodevelopmental disorders (NDD) in children with significant congenital heart disease (CHD) and to determine associated factors to NDD and frequency of follow-up in developmental therapies. Two hundred and ten children with significant CHD aged from 6 to 66 months were enrolled over a period of six months. The Ages & Stages Questionnaire Third Edition in French (ASQ-3) was used to assess neurodevelopmental domains. NDD were defined if cut-off scores were ≤ - 1SD. - 1SD corresponded to "Monitor" range: children with minor or emerging disorders; - 2SD corresponded to "Refer" range: children exhibiting neurodevelopmental delays. Forty children were in "Monitor" range and 86 in "Refer" range. NDD rate was 60.0% (n = 126, 95% CI, 53.4 to 66.6%). There was no difference regarding CHD severity (p = 0.99). Only the presence of non-cardiac disease (OR = 2.14; 95% CI, 1.11 to 4.20) was associated with NDD. Forty-six children with NDD had no developmental follow-up (among them 21 were in "Refer" range (10%)) despite this being available.Conclusion: Children with significant CHD are at risk for NDD regardless of CHD severity. Systematic and early monitoring in a specific care program is required. Barriers that prevent access of care must be identified.Trial registration: Neurodevelopmental Disorders in Children With Congenital Heart Disease. NeuroDis-CHD. NCT03360370. https://clinicaltrials.gov/ct2/show/NCT03360370 What is Known: • Children with CHD are at risk for neurodevelopmental disorders and behavioural problems impacting their social adaptation, academic achievements and quality of personal and family life even in adulthood. What is New: • Children with CHD are at risk for neurodevelopmental disorders regardless of the complexity of the CHD. • Even with the availability of appropriate developmental services, children with CHD are not correctly followed, highlighting the need of a specific program of care for a better outcome. Local barriers that prevent access of care of those children must be identified.

Pediatric chest computed tomography at 100 kVp with tin filtration: comparison of image quality with 70-kVp imaging at comparable radiation dose.

BACKGROUND: Radiation dose reduction is a primary objective in pediatric populations owing to the well-known risks of radiation-induced cancers. Low-energy photons participate in the radiation dose without significantly contributing to image formation. Their suppression by means of tin filtration should decrease the image noise, anticipating a subsequent application to dose saving. OBJECTIVE: To investigate the level of noise reduction achievable with tin (Sn) filtration at 100 kVp for chest computed tomography (CT) in comparison with a standard scanning mode at 70 kVp with comparable radiation dose. MATERIALS AND METHODS: Fifty consecutive children (Group 1) underwent non-contrast chest CT examinations on a third-generation dual-source CT system at tin-filtered 100 kVp and pitch 2. The tube-current time product (mAs) was adjusted to maintain the predicted dose length product (DLP) value at 70 kVp for the respective patient. Each child was then paired by weight and age to a child scanned at 70 kVp on the same CT unit (Group 2); Group 2 patients were consecutive patients, retrospectively selected from our database of children prospectively scanned at 70 kVp. Objective and subjective image quality were compared between the two groups of patients to investigate the overall image quality and level of noise reduction that could be subsequently achievable with tin filtration in clinical practice. RESULTS: The mean image noise was significantly lower in Group 1 compared to Group 2 when measured in the air (P<0.0001) and inside the aorta (P<0.001). The mean noise reduction was 21.6% (standard deviation [SD] 16.1) around the thorax and 12.0% (SD 32.7) inside the thorax. There was no significant difference in subjective image quality of lung and mediastinal images with excellent overall subjective scores in both groups. CONCLUSION: At comparable radiation dose, the image noise was found to be reduced by 21.6% compared to the 70-kVp protocol, providing basis for dose reduction without altering image quality in further investigations.

Differential Determinants of Tubular Phosphate Reabsorption: Insights on Renal Excretion of Phosphates in Kidney Disease.

We assessed the tubular reabsorption of phosphate (TRP) and maximal renal threshold for phosphate reabsorption to glomerular filtration rate (TmPi/GFR) and their determinants in 64 stages 2-4 chronic kidney disease (CKD) patients in order to define the early changes in phosphate metabolism in CKD. In multivariable analysis, TmPi/GFR correlates were estimated GFR (eGFR), intact parathyroid hormone (iPTH), and hemoglobin (R2 = 0.417), while TRP correlates were eGFR, iPTH, 24-h phosphaturia, and calcitriol (R2 = 0.72). This suggests that TmPi/GFR and TRP, respectively, assess hemoglobin-phosphate and bowel-kidney phosphate regulation axis. Iron supplementation based on TmPi/GFR or earlier phosphate restriction based on TRP should be investigated in view of modifying clinical outcomes in CKD.

Can the Pediatric Logistic Organ Dysfunction-2 Score on Day 1 Be Used in Clinical Criteria for Sepsis in Children?

OBJECTIVE: A recent task force has proposed the use of Sequential Organ Failure Assessment in clinical criteria for sepsis in adults. We sought to evaluate the predictive validity for PICU mortality of the Pediatric Logistic Organ Dysfunction-2 and of the "quick" Pediatric Logistic Organ Dysfunction-2 scores on day 1 in children with suspected infection. DESIGN: Secondary analysis of the database used for the development and validation of the Pediatric Logistic Organ Dysfunction-2. SETTINGS: Nine university-affiliated PICUs in Europe. PATIENTS: Only children with hypotension-low systolic blood pressure or low mean blood pressure using age-adapted cutoffs-and lactatemia greater than 2 mmol/L were considered in shock. MEASUREMENTS AND MAIN RESULTS: We developed the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 including tachycardia, hypotension, and altered mentation (Glasgow < 11): one point for each variable (range, 0-3). Outcome was mortality at PICU discharge. Discrimination (Area under receiver operating characteristic curve-95% CI) and calibration (goodness of fit test) of the scores were studied. This study included 862 children with suspected infection (median age: 12.3 mo; mortality: n = 60 [7.0%]). Area under the curve of the Pediatric Logistic Organ Dysfunction-2 score on day 1 was 0.91 (0.86-0.96) in children with suspected infection, 0.88 (0.79-0.96) in those with low systolic blood pressure and hyperlactatemia, and 0.91 (0.85-0.97) in those with low mean blood pressure and hyperlactatemia; calibration p value was 0.03, 0.36, and 0.49, respectively. A Pediatric Logistic Organ Dysfunction-2 score on day 1 greater than or equal to 8 reflected an overall risk of mortality greater than or equal to 9.3% in children with suspected infection. Area under the curve of the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 was 0.82 (0.76-0.87) with systolic blood pressure or mean blood pressure; calibration p value was 0.89 and 0.72, respectively. A score greater than or equal to 2 reflected a mortality risk greater than or equal to 19.8% with systolic blood pressure and greater than or equal to 15.9% with mean blood pressure. CONCLUSION: Among children admitted to PICU with suspected infection, Pediatric Logistic Organ Dysfunction-2 score on day 1 was highly predictive of PICU mortality suggesting its use to standardize definitions and diagnostic criteria of pediatric sepsis. Further studies are needed to determine the usefulness of the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 outside of the PICU.

Coronary calcium screening with dual-source CT: reliability of ungated, high-pitch chest CT in comparison with dedicated calcium-scoring CT.

PURPOSE: To investigate the reliability of ungated, high-pitch dual-source CT for coronary artery calcium (CAC) screening. MATERIALS AND METHODS: One hundred and eighty-five smokers underwent a dual-source CT examination with acquisition of two sets of images during the same session: (a) ungated, high-pitch and high-temporal resolution acquisition over the entire thorax (i.e., chest CT); (b) prospectively ECG-triggered acquisition over the cardiac cavities (i.e., cardiac CT). RESULTS: Sensitivity and specificity of chest CT for detecting positive CAC scores were 96.4 % and 100 %, respectively. There was excellent inter-technique agreement for determining the quantitative CAC score (ICC = 0.986). The mean difference between the two techniques was 11.27, representing 1.81 % of the average of the two techniques. The inter-technique agreement for categorizing patients into the four ranks of severity was excellent (weighted kappa = 0.95; 95 % CI 0.93-0.98). The inter-technique differences for quantitative CAC scores did not correlate with BMI (r = 0.05, p = 0.575) or heart rate (r = -0.06, p = 0.95); 87.2 % of them were explained by differences at the level of the right coronary artery (RCA: 0.8718; LAD: 0.1008; LCx: 0.0139; LM: 0.0136). CONCLUSION: Ungated, high-pitch dual-source CT is a reliable imaging mode for CAC screening in the conditions of routine chest CT examinations. KEY POINTS: • CAC is an independent risk factor for major cardiac events. • ECG-gated techniques are the reference standard for calcium scoring. • Great interest is directed toward calcium scoring on non-gated chest CT examinations. • Reliable calcium scoring can be obtained with dual-source CT in a high-pitch mode.

Characteristics of Patients with Alcohol Dependence Seeking Baclofen Treatment in France: A Two-Centre Comparative Cohort Study.

AIM: To characterize the profile of patients seeking baclofen treatment for alcohol dependence in France. METHOD: We compared retrospectively baclofen seekers and baclofen non-seekers within a cohort of consecutive outpatients with alcohol dependence who attended a first appointment for alcohol treatment at two French addiction centres between September 2012 and March 2014. We documented socio-demographic characteristics; comorbid psychiatric, addiction, alcohol dependence features; patients' initial drinking goal, and referral status; and treatment retention at 6 and 12 months. RESULTS: Of the 289 patients identified, 107 were baclofen seekers and 182 were baclofen non-seekers. The only parameters significantly associated with baclofen seekers in multivariate analyses were a greater baseline alcohol consumption (ß = 15.4, 95% CI: 0.18-30.65, P = 0.05), a controlled-drinking initial goal (OR = 14.9, 95% CI: 7.7-29, P < 0.0001) and self-referral (OR = 6.6, 95% CI: 3.7-12, P < 0.0001), baclofen seekers being eight times more likely to be self-referred and treatment-naïve (OR = 8.8, 95% CI: 4.1-18.9, P < 0.0001). Baclofen seekers were more likely to be retained in treatment at 6 months (OR = 3.5, 95% CI: 1.8-6.7, P < 0.0001) and 12 months (OR = 1.9, 95% CI: 1.1-3.2, P = 0.019). CONCLUSION: In France, the perspective of controlled drinking offered by baclofen treatment may have attracted more self-referred patients, including those without previous alcohol treatment, to attend treatment, than the usual treatment options. These findings raise the question as to whether future public health strategies on alcohol should more prominently promote some aspects of alcohol treatment, such as patient's preference and treatment options, in order to reduce the treatment gap in alcohol dependence.

Daily estimation of the severity of organ dysfunctions in critically ill children by using the PELOD-2 score.

INTRODUCTION: Daily or serial evaluation of multiple organ dysfunction syndrome (MODS) scores may provide useful information. We aimed to validate the daily (d) PELOD-2 score using the set of seven days proposed with the previous version of the score. METHODS: In all consecutive patients admitted to nine pediatric intensive care units (PICUs) we prospectively measured the dPELOD-2 score at day 1, 2, 5, 8, 12, 16, and 18. PICU mortality was used as the outcome dependent variable. The discriminant power of the dPELOD-2 scores was estimated using the area under the ROC curve and the calibration using the Hosmer-Lemeshow chi-square test. We used a logistic regression to investigate the relationship between the dPELOD-2 scores and outcome, and between the change in PELOD-2 score from day 1 and outcome. RESULTS: We included 3669 patients (median age 15.5 months, mortality rate 6.1%, median length of PICU stay 3 days). Median dPELOD-2 scores were significantly higher in nonsurvivors than in survivors (p < 0.0001). The dPELOD-2 score was available at least at day 2 in 2057 patients: among the 796 patients without MODS on day 1, 186 (23.3%) acquired the syndrome during their PICU stay (mortality 4.9% vs. 0.3% among the 610 who did not; p < 0.0001). Among the 1261 patients with MODS on day 1, the syndrome worsened in 157 (12.4%) and remained unchanged or improved in 1104 (87.6%) (mortality 22.9% vs. 6.6%; p < 0.0001). The AUC of the dPELOD-2 scores ranged from 0.75 (95% CI: 0.67-0.83) to 0.89 (95% CI: 0.86-0.91). The calibration was good with a chi-square test between 13.5 (p = 0.06) and 0.9 (p = 0.99). The PELOD-2 score on day 1 was a significant prognostic factor; the serial evaluation of the change in the dPELOD-2 score from day1, adjusted for baseline value, demonstrated a significant odds ratio of death for each of the 7 days. CONCLUSION: This study suggests that the progression of the severity of organ dysfunctions can be evaluated by measuring the dPELOD-2 score during a set of 7 days in PICU, providing useful information on outcome in critically ill children. Its external validation would be useful.

Nonrespiratory pediatric logistic organ dysfunction-2 score is a good predictor of mortality in children with acute respiratory failure.

OBJECTIVE: Multiple organ dysfunction, not respiratory failure, is the major cause of death in children with acute lung injury or acute respiratory distress syndrome. This study was undertaken to estimate the predictive value of death of the nonrespiratory Pediatric Logistic Organ Dysfunction-2 in children with acute respiratory failure. DESIGN: Analysis of the database of the recently published Pediatric Logistic Organ Dysfunction-2. SETTING: Nine multidisciplinary, tertiary-care PICU of university-affiliated hospitals in France and Belgium. PATIENTS: All consecutive children (excluding neonates) admitted to these PICUs (June 2006 to October 2007) and having acute respiratory failure. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: We prospectively collected data on variables considered for the Pediatric Logistic Organ Dysfunction-2 score during PICU stay up to eight time points: days 1, 2, 5, 8, 12, 16, and 18, plus PICU discharge. For each variable considered in the Pediatric Logistic Organ Dysfunction-2 score, the most abnormal value observed during time points was collected. Outcome was vital status at PICU discharge. We used areas under receiver operating characteristic curve to estimate the discrimination and Hosmer-Lemeshow goodness-of-fit tests to estimate calibration of the Pediatric Logistic Organ Dysfunction-2 and the nonrespiratory Pediatric Logistic Organ Dysfunction-2 scores, with correction for the optimism bias using a bootstrap resampling method. We included 1,572 consecutive patients (median age, 20.6 months; interquartile range, 5.5-80.2; mortality rate, 9.5%). Discrimination of the Pediatric Logistic Organ Dysfunction-2 and the nonrespiratory Pediatric Logistic Organ Dysfunction-2 were excellent (areas under receiver operating characteristic curve = 0.93 and 0.92, respectively) and calibration (chi-square test for goodness-of-fit = 5.8, p = 0.45 and 7.6, p = 0.27, respectively) was good. The four nonrespiratory organ dysfunctions were closely related to the risk of mortality (p< 0.001). CONCLUSION: Our study demonstrates that the nonrespiratory Pediatric Logistic Organ Dysfunction-2 score of the entire PICU stay is highly predictive of death in children with acute respiratory failure of whom 94.3% were invasively ventilated. The nonrespiratory Pediatric Logistic Organ Dysfunction-2 score could represent the nonrespiratory organ failure definition tool whose development was recommended in the international expert recommendations on pediatric acute respiratory distress syndrome.

Perception of aesthetic impairment in patients with systemic sclerosis determined using a semi-quantitative scale and its association with disease characteristics.

Background: Systemic sclerosis is a fibrotic disease. Body image assessments could be key in optimizing care; however, data are scarce. The main objective was to assess the perception of aesthetic impairment using a visual aesthetic evaluation scale in patients with systemic sclerosis compared with healthy subjects. The secondary objectives were to assess associations between the perception of aesthetic impairment and scores on standardized questionnaires for aesthetic impairment as well as clinical, psychological/quality of life, and functional parameters of patients with systemic sclerosis. Methods: This study evaluated and compared the perception of aesthetic impairment in two populations: patients with systemic sclerosis from a referral center at Lille Hospital, France, and healthy controls. Results: This study included 88 patients (69 (78.4%) women) with a median age of 52 years and 88 controls (49 (55.7%) women) with a median age of 45 years. The perception of aesthetic impairment assessed using the aesthetic evaluation scale was poorer in systemic sclerosis patients than in controls (3.7 ± 0.3 vs 2.8 ± 0.3, p = 0.028) and was statistically correlated with assessments using the adapted satisfaction with appearance, a specific aesthetic impact assessment questionnaire for patients with systemic sclerosis. Patients with anxiety or depressive symptoms had significantly higher aesthetic evaluation scale scores. Systemic sclerosis patients with facial involvement and pitting scars had a worse perception of aesthetic impairment. Compared with healthy controls, systemic sclerosis patients had a worse perception of aesthetic impairment, especially systemic sclerosis patients with anxiety or depression and those with facial and hand involvement. Conclusion: The aesthetic evaluation scale appears to be an easy-to-use tool to evaluate body image. Correlations of the aesthetic evaluation scale score with psychological and quality of life parameters reflect the importance of these parameters for body image evaluation and its complex assessment. Trial registration: Clinical Trial NCT03271320 (Registered 9 January 2017, https://www.clinicaltrials.gov/ct2/show/NCT03271320?term=NCT03271320&cntry=FR&draw=2&rank=1).

Perfusion CT allows prediction of therapy response in non-small cell lung cancer treated with conventional and anti-angiogenic chemotherapy.

OBJECTIVES: To determine whether CT can depict early perfusion changes in lung cancer treated by anti-angiogenic drugs, allowing prediction of response. METHODS: Patients with non-small cell lung cancer, treated by conventional chemotherapy with (Group 1; n = 17) or without (Group 2; n = 23) anti-vascular endothelial growth factor (anti-VEGF) drug (bevacizumab) underwent CT perfusion before (TIME 0) and after 1 (TIME 1), 3 (TIME 2) and 6 (TIME 3) cycles of chemotherapy. The CT parameters evaluated included: (1) total tumour vascular volume (TVV) and total tumour extravascular flow (TEF); (2) RECIST (Response Evaluation Criteria in Solid Tumours) measurements. Tumour response was also assessed on the basis of the clinicians' overall evaluation. RESULTS: In Group 1, significant reduction in perfusion was identified between baseline and: (1) TIME 1 (TVV, P = 0.0395; TEF, P = 0.015); (2) TIME 2 (TVV, P = 0.0043; TEF, P < 0.0001); (3) TIME 3 (TVV, P = 0.0034; TEF, P = 0.0005) without any significant change in Group 2. In Group 1: (1) the reduction in TVV at TIME 1 was significantly higher in responders versus non-responders at TIME 2 according to RECIST (P = 0.0128) and overall clinicians' evaluation (P = 0.0079); (2) all responders at TIME 2 had a concurrent decrease in TVV and TEF at TIME 1. CONCLUSION: Perfusion CT demonstrates early changes in lung cancer vascularity under anti-angiogenic chemotherapy that may help predict therapeutic response. KEY POINTS: • Perfusion CT has the potential of providing in vivo information about tumour vasculature. • CT depicts early and specific perfusion changes in NSCLC under anti-angiogenic drugs. • Specific therapeutic effects of anti-angiogenic drugs can be detected before tumour shrinkage. • Early perfusion changes can help predict therapeutic response to anti-angiogenic treatment. • Perfusion CT could be a non-invasive tool to monitor anti-angiogenic treatment.

Bone Marrow Adiposity and Fragility Fractures in Postmenopausal Women: The ADIMOS Case-Control Study.

CONTEXT: Noninvasive assessment of proton density fat fraction (PDFF) by magnetic resonance imaging (MRI) may improve the prediction of fractures. OBJECTIVE: This work aimed to determine if an association exists between PDFF and fractures. METHODS: A case-control study was conducted at Lille University Hospital, Lille, France, with 2 groups of postmenopausal women: one with recent osteoporotic fractures, and the other with no fractures. Lumbar spine and proximal femur (femoral head, neck, and diaphysis) PDFF were determined using chemical shift-based water-fat separation MRI (WFI) and dual-energy x-ray absorptiometry scans of the lumbar spine and hip. Our primary objective was to determine the relationship between lumbar spine PDFF and osteoporotic fractures in postmenopausal women. Analysis of covariance was used to compare PDFF measurements between patient cases (overall and according to the type of fracture) and controls, after adjusting for age, Charlson comorbidity index (CCI) and BMD. RESULTS: In 199 participants, controls (n = 99) were significantly younger (P < .001) and had significantly higher BMD (P < 0.001 for all sites) than patient cases (n = 100). A total of 52 women with clinical vertebral fractures and 48 with nonvertebral fractures were included. When PDFFs in patient cases and controls were compared, after adjustment on age, CCI, and BMD, no statistically significant differences between the groups were found at the lumbar spine or proximal femur. When PDFFs in participants with clinical vertebral fractures (n = 52) and controls were compared, femoral neck PDFF and femoral diaphysis PDFF were detected to be lower in participants with clinical vertebral fractures than in controls (adjusted mean [SE] 79.3% [1.2] vs 83.0% [0.8]; P = 0.020, and 77.7% [1.4] vs 81.6% [0.9]; P = 0.029, respectively). CONCLUSION: No difference in lumbar spine PDFF was found between those with osteoporotic fractures and controls. However, imaging-based proximal femur PDFF may discriminate between postmenopausal women with and without clinical vertebral fractures, independently of age, CCI, and BMD.

Obstetrical outcomes in cases of maternal heart disease with a risk of cardiac decompensation: A retrospective study since the establishment of a multidisciplinary consultation meeting "heart and pregnancy".

BACKGROUND: Pregnant women with chronic heart failure (CHF) are at increased risk for cardiac complications. However, the frequency of obstetrical and neonatal complications in pregnant women with CHF remains unclear. OBJECTIVE: The objective of our study was to describe obstetrical and neonatal outcomes in pregnant with CHF. METHOD: This single-center retrospective cohort study involves pregnant women with a CHF who delivered at Jeanne de Flandre, the Lille's university hospital, from 2017 to 2021. The frequency of obstetrical, neonatal, and cardiovascular complications was collected. RESULT: During this period, we identified 26 pregnant women with a CHF. The main cardiac diseases responsible for CHF were cardiomyopathies (53.8%) and congenital heart disease (46.2%). Acute heart failure occurred in 30.8% of the cases and mainly concerned patients with no follow-up of their heart disease. The main obstetrical complications were fetal growth restriction (38.5%) and premature rupture of fetal membranes (19.2%). The 26 pregnancies comprised 25 live births and 1 stillbirth. Newborn infants were delivered via cesarean in 69.2%. Of the live births, 60% were preterm at a median gestational age of 36 (34-38) weeks. CONCLUSION: Pregnant women with CHF had a higher risk for obstetrical and neonatal outcomes.

Surgical intervention after transvaginal Prolift mesh repair: retrospective single-center study including 524 patients with 3 years' median follow-up.

OBJECTIVE: The aim of this study was to explore the nature and rate of surgical intervention after transvaginal Prolift mesh repair for pelvic organ prolapse. STUDY DESIGN: This was a retrospective study of all patients who underwent Prolift mesh repair between January 2005 and January 2009. Patient data were obtained from medical records, and patients were telephoned to check if they had surgery in other hospitals. RESULTS: A total of 600 consecutive patients were identified. Of these, 524 patients (87.3%) were included in the study, with a median follow-up duration of 38 months (range, 15-63). Global reoperation rate was 11.6%. Indications of intervention were surgery for urinary incontinence (6.9%), mesh-related complications (3.6%), or prolapse recurrence (3%). CONCLUSION: The global reoperation rate after transvaginal Prolift mesh repair was 11.6%, with urinary incontinence surgery being the most common indication. Rates of mesh complications and prolapse recurrence are relatively low in an experienced team.

Maternal anxiety and pain during prenatal diagnostic techniques: a prospective study.

OBJECTIVE: To explore anxiety and pain felt by women undergoing chorionic villus sampling (CVS) and amniocentesis (AC). METHOD: We prospectively questioned 254 women (67 undergoing CVS, 187 AC) before the procedure on their anxiety, after the procedure on their pain felt, and the support they received or desired. The medical team collected technical information concerning each procedure. RESULTS: The level of anxiety was significantly higher in women undergoing CVS than AC, in those who had received complete information before the procedure, and when indication for the procedure was fetal structural abnormalities. The level of pain was significantly higher in cases of anxious women, those undergoing a CVS rather than AC, those who had undergone invasive prenatal diagnostic procedures in previous pregnancies, in procedures deemed difficult by the operator, and with needle insertion in the lateral part of the uterus. About 30% of women undergoing CVS and 8% of those undergoing AC would have desired some form of pain prevention, mostly with nonpharmacologic therapy. CONCLUSION: Prenatal diagnosis is frequently associated with anxiety and pain. We identified factors that could exacerbate either one. When questioned, patients would desire a nonpharmacologic means for pain prevention.

A feasible and reliable self-administered parental assessment of children's lifestyle (SAPLACL): an ancillary study based on the VIF program.

OBJECTIVES: In children, achieving an acceptable degree of accuracy from dietary or physical activity (PA) assessments remains a challenge. Children tend to overestimate their time spent in daily PA and underestimate their dietary intake of fat and sugar. Because parents play a key role in family lifestyle decisions, including children's food choices and PA levels, it is important to investigate the responses of parents regarding their children's lifestyle habits. We aimed to develop a Self-Administered Parental Assessment of Children's Lifestyle (SAPLACL) questionnaire and test its feasibility and reliability in 191 parents (29 fathers and 162 mothers). RESULTS: For each part of the questionnaire, the rate of missing or improper responses ranged from 0 to 24%. The highest proportion of problems in understanding was reported for the dietary intake dimension, especially for snacking in front of the TV. Some difficulty was also found regarding the question on leisure PA. Test-retest agreement was observed in 54.7-100% of the respondents. Overall, the kappa coefficients were favorable. Thus, the parent self-report questionnaire is a valid and accurate tool for analyzing children's lifestyle habits in France.

Whole pulmonary assessment 1 year after paediatric acute respiratory distress syndrome: prospective multicentre study.

BACKGROUND: Long-term pulmonary sequelae, including 1-year thoracic computed tomography (CT) sequelae of paediatric acute respiratory distress syndrome (ARDS) remain unknown. The purpose of the study was to determine pulmonary abnormalities in child survivors of pulmonary (p-ARDS) and extra-pulmonary ARDS (ep-ARDS) 1 year after paediatric intensive care unit discharge (PICUD). METHODS: Prospective multicentre study in four paediatric academic centres between 2005 and 2014. Patients with ARDS were assessed 1 year after PICUD with respiratory symptom questionnaire, thoracic CT and pulmonary function tests (PFT). RESULTS: 39 patients (31 p-ARDS) aged 1.1-16.2 years were assessed. Respiratory symptoms at rest or exercise and/or respiratory maintenance treatment were reported in 23 (74%) of children with p-ARDS but in 1 (13%) of those with ep-ARDS. Thoracic CT abnormalities were observed in 18 (60%) of children with p-ARDS and 4 (50%) of those with ep-ARDS. Diffuse and more important CT abnormalities, such as ground glass opacities or mosaic perfusion patterns, were observed in 5 (13%) of children, all with p-ARDS. PFT abnormalities were observed in 30 (86%) of patients: lung hyperinflation and/or obstructive pattern in 12 (34%) children, restrictive abnormalities in 6 (50%), mild decrease in diffusing capacity in 2 (38%) and 6-min walking distance decrease in 11 (73%). Important PFT abnormalities were observed in 7 (20%) children, all with p-ARDS. Increasing driving pressure (max plateau pressure-max positive end-expiratory pressure) was correlated with increasing CT-scan abnormalities and increasing functional residual capacity (more hyperinflation) (p < 0.005). CONCLUSIONS: Children surviving ARDS requiring mechanical ventilation present frequent respiratory symptoms, significant CT-scan and PFT abnormalities 1 year after PICUD. This highlights the need for a systematic pulmonary assessment of these children. Trial registration The study was registered on Clinical Trials.gov PRS (ID NCT01435889).
