Oral famotidine reduces the plasma level of soluble P-selectin in children with sickle cell disease.

Plasma histamine levels are increased in patients with sickle cell disease (SCD), potentially promoting endothelial P-selectin expression and vaso-occlusion via histamine type 2 (H2) receptors. We conducted a prospective, non-comparative, single-centre study to determine whether famotidine, a H2 receptor antagonist, reduces P-selectin expression in SCD children. The median plasma P-selectin level was significantly reduced after 29 days of oral famotidine (53.2 ng/mL [IQR: 46.7-63.4] vs. 69.9 ng/mL [IQR: 53.6-84.2], median difference -10.2 ng/mL [IQR: -21.8 to -2.7], p = 0.005) in 28 patients. No effect was observed on other adhesion molecules, inflammation or haemolysis markers, except decreased reticulocyte count. No adverse events deemed related to famotidine were observed. Randomized controlled trials are now needed to assess the efficacy of famotidine in preventing vaso-occlusion in SCD.

CEA, CA19-9, circulating DNA and circulating tumour cell kinetics in patients treated for metastatic colorectal cancer (mCRC).

BACKGROUND: We previously reported that CEA kinetics are a marker of progressive disease (PD) in metastatic colorectal cancer (mCRC). This study was specifically designed to confirm CEA kinetics for predicting PD and to evaluate CA19-9, cell-free DNA (cfDNA), circulating tumour DNA (ctDNA) and circulating tumour cell (CTC) kinetics. METHODS: Patients starting a chemotherapy (CT) with pre-treatment CEA > 5 ng/mL and/or CA19.9 > 30 UI/mL were prospectively included. Samples were collected from baseline to cycle 4 for CEA and CA19-9 and at baseline and the sixth week for other markers. CEA kinetics were calculated from the first to the third or fourth CT cycle. RESULTS: A total of 192 mCRC patients were included. CEA kinetics based on the previously identified >0.05 threshold was significantly associated with PD (p < 0.0001). By dichotomising by the median value, cfDNA, ctDNA and CA19-9 were associated with PD, PFS and OS in multivariate analysis. A circulating scoring system (CSS) combining CEA kinetics and baseline CA19-9 and cfDNA values classified patients based on high (n = 58) and low risk (n = 113) of PD and was independently associated with PD (ORa = 4.6, p < 0.0001), PFS (HRa = 2.07, p < 0.0001) and OS (HRa = 2.55, p < 0.0001). CONCLUSIONS: CEA kinetics alone or combined with baseline CA19-9 and cfDNA are clinically relevant for predicting outcomes in mCRC. TRIAL REGISTRATION NUMBER: NCT01212510.

Role of oculocerebrorenal syndrome of Lowe (OCRL) protein in megakaryocyte maturation, platelet production and functions: a study in patients with Lowe syndrome.

Lowe syndrome (LS) is an oculocerebrorenal syndrome of Lowe (OCRL1) genetic disorder resulting in a defect of the OCRL protein, a phosphatidylinositol-4,5-bisphosphate 5-phosphatase containing various domains including a Rho GTPase-activating protein (RhoGAP) homology domain catalytically inactive. We previously reported surgery-associated bleeding in patients with LS, suggestive of platelet dysfunction, accompanied with a mild thrombocytopenia in several patients. To decipher the role of OCRL in platelet functions and in megakaryocyte (MK) maturation, we conducted a case-control study on 15 patients with LS (NCT01314560). While all had a drastically reduced expression of OCRL, this deficiency did not affect platelet aggregability, but resulted in delayed thrombus formation on collagen under flow conditions, defective platelet spreading on fibrinogen and impaired clot retraction. We evidenced alterations of the myosin light chain phosphorylation (P-MLC), with defective Rac1 activity and, inversely, elevated active RhoA. Altered cytoskeleton dynamics was also observed in cultured patient MKs showing deficient proplatelet extension with increased P-MLC that was confirmed using control MKs transfected with OCRL-specific small interfering(si)RNA (siOCRL). Patients with LS also had an increased proportion of circulating barbell-shaped proplatelets. Our present study establishes that a deficiency of the OCRL protein results in a defective actomyosin cytoskeleton reorganisation in both MKs and platelets, altering both thrombopoiesis and some platelet responses to activation necessary to ensure haemostasis.

Accuracy of saliva and nasopharyngeal sampling for detection of SARS-CoV-2 in community screening: a multicentric cohort study.

Nasopharyngeal sampling for nucleic acid amplification testing (NAAT) is the standard diagnostic test of coronavirus disease 2019. Our objectives were to assess, in real-life conditions, the diagnostic accuracy of a nasopharyngeal point-of-care antigen (Ag) test and of saliva NAAT for detection of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in ambulatory care. This was a prospective cohort study from 19 October through 18 December 2020 in two community COVID-19 screening centers in Paris, France. Two nasopharyngeal swabs and one saliva sample were simultaneously collected. Diagnostic accuracies of nasopharyngeal Ag testing and of three saliva NAAT methods were assessed as compared to nasopharyngeal NAAT. A total of 1452 ambulatory children and adults were included. Overall, 129/1443 (9%) participants tested positive on nasopharyngeal NAAT (102/564 [18%] in symptomatic and 27/879 [3%] in asymptomatic participants). Sensitivity was 94%, 23%, 96%, and 94% for the three different protocols of saliva NAAT and for the nasopharyngeal Ag test, respectively. Estimates of specificity were above 95% for all methods. Diagnostic accuracy was similar in symptomatic and asymptomatic individuals. Diagnostic accuracy of nasopharyngeal Ag testing and of saliva NAAT is similar to that of nasopharyngeal NAAT, subject to compliance with specific protocols for saliva. Registration number: NCT04578509.

Therapeutic plasma exchange for life-threatening pediatric disorders.

INTRODUCTION: Therapeutic plasma exchange (TPE) is acknowledged to be an effective treatment in life-threatening pediatric disorders. Apheresis for pediatric diseases has been poorly investigated, and most studies to date featured small numbers of patients and lacked control groups. The objective of the present study was to evaluate the tolerance of TPE in pediatric patients. MATERIALS AND METHODS: A retrospective cohort study via a web-based electronic case report form including pediatric patients referred for TPE between January 2005 and December 2014. RESULTS: A total of 78 patients (median [range] age: 9.8 [0.53-17.93]) and 731 TPE procedures were analyzed. The indications were antibody-mediated rejection (n = 33; 42%) and desensitization therapy (n = 5; 6%) after solid organ or hematopoietic stem cell transplantation, thrombotic microangiopathy (n = 17; 22%), pediatric inflammatory diseases (n = 16; 21%), kidney diseases (n = 6; 8%), and hyperviscosity syndrome (n = 1; 1%). On average, each patient underwent six procedures during the first session [range: 1-19]. In the 2 weeks following the start of a session, 72 patients (92%) presented a total of 311 adverse events (AEs) potentially related to TPE. The risk of AEs was not related to the indication for TPE, the intensity of care, venous access, plasma substitute use, or body weight. None of the deaths was related to the TPE. CONCLUSION: We studied one of the largest retrospective pediatric cohorts described to date. Our experience of TPE children's TPE feasibility concerned specific, life-threatening conditions and otherwise treatment-refractory diseases.

Faecal calprotectin and gut microbiota do not predict enteropathy in very preterm infants.

AIM: Very preterm birth is associated with a high risk of enteropathies. Diagnosis is challenging, especially in mild forms, leading to unnecessary periods of cessation of enteral feeding. This study aimed at establishing a prognosis score of enteropathy combining clinical parameters and faecal calprotectin concentration. METHODS: This prospective multicentric study included preterm neonates born at a gestational age of 33 weeks or less. Stools were collected weekly until hospital discharge, and daily in case of digestive events for calprotectin measurement (ELISA and immunochromatography) and microbiota analyses (16S rRNA gene sequencing). RESULTS: Among the 121 neonates included, 21 experienced at least one episode of enteropathy, mainly mild forms. By ELISA testing, median faecal calprotectin was 88 (8-798) µg/g faeces. No statistically significant association was found between the outset of enteropathy and maternal and neonatal characteristics, and calprotectin levels. The agreement between ELISA and immunochromatography assay was moderate (intra-class correlation coefficient 0.58, 95%CI [0.47-0.66]). Comparison of species diversity and relative bacterial abundance profiles between infants with or without enteropathy revealed no specific alterations associated with enteropathy. CONCLUSION: The study failed to propose a prognostic score of enteropathy, probably due the large inter- and intra-individual variability of faecal calprotectin in very preterm neonates.

One-way self-expanding rod for early-onset scoliosis: early results of a clinical trial of 20 patients.

PURPOSE: Progressive early-onset scoliosis raises major challenges for surgeons, as growth must be preserved. With traditional growing rods, the need for repeated surgery is associated with numerous complications, high costs, and heavy psychosocial burden on the patient and family. We assessed the safety and efficacy of a new one-way self-expanding rod (OWSER). METHODS: This prospective single-centre phase 2 study included two groups of children with progressive EOS treated by the OWSER in 2016-2017: Ten received a unilateral construct to treat progressive non-neuromuscular curves and 10 others a bilateral construct for neuromuscular scoliosis. Clinical and radiological data were assessed at surgery and 3, 6, 12, 18 months later. The primary endpoint was success defined as the absence of repeated surgery at 12 months. RESULTS: In the non-neuromuscular group, rod expansion occurred in 5 of 10 patients [95% CI 19-81]; in the five other patients, rotational conflict inside the domino prevented rod expansion, four of them required surgery within the first 12 months. Rod expansion occurred spontaneously and during monthly traction sessions in all 10 neuromuscular patients [95% CI 69-100], without mechanical or device-related complications. Residual pelvic obliquity was improved by -3° [- 6.0 to 9.5] at 18 months. Lung function improved in the non-neuromuscular group. CONCLUSION: In neuromuscular diseases, the OWSER bilateral construct seems to be safe and less aggressive. Used as unilateral construct in non-neuromuscular group, it was less effective. Accordingly, we recommend the bilateral construct for all aetiologies. That device could avoid further surgery and reduce the rate of complications after long follow-up.

Prenatal education of overweight or obese pregnant women to prevent childhood overweight (the ETOIG study): an open-label, randomized controlled trial.

BACKGROUND: We aimed to evaluate whether pre and perinatal education of pregnant women would reduce childhood overweight. METHODS: Four French centers included women at ≤21 gestational weeks (GWs) with body mass index (BMI) >25 kg/m2 before pregnancy. Patients were randomized to a control group (routine care including at least one dietary visit) or an intervention group (2 individuals (26 and 30 GW) and 4 group sessions (21, 28, 35 GW, 2 months postpartum)) aimed at educating the future mother regarding infant and maternal nutrition. The primary objective was to reduce post-natal excessive weight gain in the infant from birth to 2 years (NCT00804765). This project was funded by a grant from the National Programme for Hospital Research (PHRC-2007 French Ministry of Health). RESULTS: We included 275 women (BMI: 32.5 kg/m2). The rate of post-natal excessive weight gain was similar in the intervention (n = 132) and control (n = 136) groups by intention to treat (ITT: 59.1% vs 60.3% respectively, p = 0.84) in available data (AD, n = 206) and by per-protocol analysis (PP, n = 177). Two years after delivery, normalization of maternal BMI and number of infants with BMI < 19 kg/m2 were not significantly different in the interventional group in ITT and in the control group. Although not significantly different in ITT, normalization of maternal BMI was more frequent in AD (n = 149: 12.9% vs 3.8%, p = 0.04) and 2-year-old infant BMIs were less likely to be >19 kg/m2 in the intervention group in AD (n = 204: 0% vs 6.8%, p = 0.014) and PP (n = 176: 0% vs 6.4%, p = 0.03). CONCLUSIONS: An education and nutritional counseling program for overweight women, starting after 3 months of gestation, did not significantly change post-natal excessive weight gain of infants or prevent overweight in mothers and children 2 years after delivery.

Glibenclamide oral suspension: Suitable and effective in patients with neonatal diabetes.

BACKGROUND: Results of genetic have led to off-label glibenclamide treatment in patients with neonatal diabetes (NDM) because of potassium channel mutations. No pediatric form of glibenclamide was available. Glibenclamide was designated an orphan drug designation for NDM and a suspension was developed. As a part of the pediatric plan investigation, we assessed its acceptability, efficiency, and safety. METHODS: In this Phase II, prospective, non-randomized, single-center study, patient received glibenclamide tablets for 1 month then the suspension for 3 months. We assessed acceptability using hedonic scales and patient questionnaires, effectiveness using glycated hemoglobin (HbA1C) assays and safety based on hypo and hyperglycemia, and other adverse events. RESULTS: We included 10 patients (0.1-16.2 years, 6 < 5 years) were included. Younger patients preferred the suspension and older the tablets. All parents were satisfied with the ease of suspension administration. The parents of 5 of 6 younger children preferred the suspension over the tablets and kept it. Switching from tablets to suspension did not affect the excellent metabolic control (median HbA1c change, -0.40%, [-1.3% to 0.5%] P = 0.08). Median frequencies of hypoglycemia and hyperglycemia were less than 5% of routine blood glucose assays and were similar with both dosage forms. Two patients each experienced one episode of hypoglycemia below 35 mg/dL highlighting the need for dosage titration when switching from tablets to suspension. Transient and non-severe abdominal pain or diarrhea occurred in three patients. None of the patients discontinued the treatment. CONCLUSION: The glibenclamide oral suspension Amglidia, the first anti-diabetic drug specifically developed for pediatric patients, is acceptable, effective, and safe in patients with NDM (NCT02375828).

Segregation of mitochondrial DNA mutations in the human placenta: implication for prenatal diagnosis of mtDNA disorders.

BACKGROUND: Mitochondrial DNA (mtDNA) disorders have a high clinical variability, mainly explained by variation of the mutant load across tissues. The high recurrence risk of these serious diseases commonly results in requests from at-risk couples for prenatal diagnosis (PND), based on determination of the mutant load on a chorionic villous sample (CVS). Such procedures are hampered by the lack of data regarding mtDNA segregation in the placenta.The objectives of this report were to determine whether mutant loads (1) are homogeneously distributed across the whole placentas, (2) correlate with those in amniocytes and cord blood cells and (3) correlate with the mtDNA copy number. METHODS: We collected 11 whole placentas carrying various mtDNA mutations (m.3243A>G, m.8344A>G, m.8993T>G, m.9185T>C and m.10197G>A) and, when possible, corresponding amniotic fluid samples (AFSs) and cord blood samples. We measured mutant loads in multiple samples from each placenta (n= 6-37), amniocytes and cord blood cells, as well as total mtDNA content in placenta samples. RESULTS: Load distribution was homogeneous at the sample level when average mutant load was low (<20%) or high (>80%) at the whole placenta level. By contrast, a marked heterogeneity was observed (up to 43%) in the intermediate range (20%-80%), the closer it was to 40%-50% the mutant load, the wider the distribution. Mutant loads were found to be similar in amniocytes and cord blood cells, at variance with placenta samples. mtDNA content correlated to mutant load in m.3243A>G placentas only. CONCLUSION: These data indicate that (1) mutant load determined from CVS has to be interpreted with caution for PND of some mtDNA disorders and should be associated with/substituted by a mutant load measurement on amniocytes; (2) the m.3243A>G mutation behaves differently from other mtDNA mutations with respect to the impact on mtDNA copy number, as previously shown in human preimplantation embryogenesis.

ADJUVITE: a double-blind, randomised, placebo-controlled trial of adalimumab in early onset, chronic, juvenile idiopathic arthritis-associated anterior uveitis.

OBJECTIVES: To assess the efficacy and safety of adalimumab on uveitis in patients with early onset, chronic, juvenile idiopathic arthritis (JIA)-associated or idiopathic anterior uveitis and an inadequate response to topical steroids and methotrexate (MTX). METHODS: Patients aged 4 years or more with ocular inflammation quantified by laser flare photometry (LFP) ≥30 photon units/ms were double-blindly randomised (1:1) to 2 groups, one treated with placebo and one with adalimumab subcutaneously at a dose of 24 mg/m2 in patients aged <13 years, 40 mg in the others, every other week. The primary outcome was response at month 2 (M2) defined as a 30% reduction of inflammation on LFP in the assessable eye with more severe baseline inflammation and no worsening on slit lamp examination. From M2 to M12, all patients received adalimumab. RESULTS: At M2, among 31 patients included in intention-to-treat analysis, there were 9/16 responders on adalimumab and 3/15 on placebo (P=0.038, Χ2 test; relative risk=2.81, 95% CI 0.94 to 8.45; risk difference: 36.3%, 95% CI 2.1 to 60.6); there was no significant difference using the Standardised Uveitis Nomenclature classification criteria of improvement. Thirty patients continued the trial after M2 and received adalimumab (open-label phase), 29 reached M12. There were seven serious adverse events none related to study treatment. CONCLUSIONS: This trial is in favour of using adalimumab in patients with early onset, chronic anterior uveitis, which is in most cases associated with JIA, in case of inadequate response to topical therapy and MTX. LFP could be a valuable tool to assess early treatment efficacy. TRIAL REGISTRATION NUMBER: NCT01385826.

Surgery is not superior to dilation for the management of vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome: a multicenter comparative observational study in 131 patients.

BACKGROUND: Vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome can be managed either by various surgeries or dilation. The choice still depends on surgeon's preferences rather than on quality comparative studies and validated protocols. OBJECTIVE: We sought to compare dilation and surgical management of vaginal agenesis in Mayer-Rokitansky-Küster-Hauser syndrome, in terms of quality of life, anatomical results, and complications in a large multicenter population. STUDY DESIGN: Our multicenter study included 131 patients >18 years, at least 1 year after completing vaginal agenesis management. All had an independent gynecological evaluation including a standardized pelvic exam, and completed the World Health Organization Quality of Life instrument (general quality of life) as well as the Female Sexual Function Index and Female Sexual Distress Scale-Revised (sexual quality of life) scales. Groups were: surgery (N = 84), dilation therapy (N = 26), and intercourse (N = 20). One patient was secondarily excluded because of incomplete surgical data. For statistics, data were compared using analysis of variance, Student, Kruskal-Wallis, Wilcoxon, and Student exact test. RESULTS: Mean age was 26.5 ± 5.5 years at inclusion. In all groups, World Health Organization Quality of Life scores were not different between patients and the general population except for lower psychosocial health and social relationship scores (which were not different between groups). Global Female Sexual Function Index scores were significantly lower in the surgery and dilation therapy groups (median 26 range [2.8-34.8] and 24.7 [2.6-34.4], respectively) than the intercourse group (30.2 [7.8-34.8], P = .044), which had a higher score only in the satisfaction dimension (P = .004). However, the scores in the other dimensions of Female Sexual Function Index were not different between groups. The Female Sexual Distress Scale-Revised median scores were, respectively, 17 [0-52], 20 [0-47], and 10 [10-40] in the surgery, dilation therapy, and intercourse groups (P = .38), with sexual distress in 71% of patients. Median vaginal depth was shorter in dilatation therapy group (9.6 cm [5.5-12]) compared to surgery group (11 cm [6-15]) and intercourse group (11 cm [6-12.5]) (P = .039), but remained within normal ranges. One bias in the surgery group was the high number of sigmoid vaginoplasties (57/84, 68%), but no differences were observed between surgeries. Only 4 patients achieved vaginas <6.5 cm. Delay between management and first intercourse was 6 months (not significant). Seventy patients (53%) had dyspareunia (not significant), and 17 patients all from the surgery group had an abnormal pelvic exam. In the surgery group, 34 patients (40.5%) had complications, requiring 20 secondary surgeries in 17 patients, and 35 (42%) needed postoperative dilation. In the dilation therapy group, 13 (50%) needed maintenance dilation. CONCLUSION: Surgery is not superior to therapeutic or intercourse dilation, bears complications, and should therefore be only a second-line treatment. Psychological counseling is mandatory at diagnosis and during therapeutic management.

Prognostic factors of disease severity in infants with sickle cell anemia: A comprehensive longitudinal cohort study.

In order to identify very early prognostic factors that can provide insights into subsequent clinical complications, we performed a comprehensive longitudinal multi-center cohort study on 57 infants with sickle cell anemia (55 SS; 2 Sß°) during the first 2 years of life (ClinicalTrials.gov: NCT01207037). Time to first occurrence of a severe clinical event-acute splenic sequestration (ASS), vaso-occlusive (VOC) event requiring hospitalization, transfusion requirement, conditional/ abnormal cerebral velocities, or death-was used as a composite endpoint. Infants were recruited at a mean age of 4.4 ±1 months. Median follow-up was 19.4 months. During the study period, 38.6% of infants experienced ≥1 severe event: 14% ASS, 22.8% ≥ 1 VOC (median age: 13.4 and 12.8 months, respectively) and 33.3% required transfusion. Of note, 77% of the cohort was hospitalized, with febrile illness being the leading cause for admission. Univariate analysis of various biomarkers measured at enrollment showed that fetal hemoglobin (HbF) was the strongest prognostic factor of subsequent severe outcome. Other biomarkers measured at enrolment including absolute neutrophil or reticulocyte counts, expression of erythroid adhesion markers, % of dense red cells, cellular deformability or ϒ-globin genetic variants, failed to be associated with severe clinical outcome. Multivariate analysis demonstrated that higher Hb concentration and HbF level are two independent protective factors (adjusted HRs (95% CI) 0.27 (0.11-0.73) and 0.16 (0.06-0.43), respectively). These findings imply that early measurement of HbF and Hb levels can identify infants at high risk for subsequent severe complications, who might maximally benefit from early disease modifying treatments.

Effect of Cell-Free DNA Screening vs Direct Invasive Diagnosis on Miscarriage Rates in Women With Pregnancies at High Risk of Trisomy 21: A Randomized Clinical Trial.

Importance: Cell-free DNA (cfDNA) tests are increasingly being offered to women in the first trimester of pregnancies at a high risk of trisomy 21 to decrease the number of required invasive fetal karyotyping procedures and their associated miscarriages. The effect of this strategy has not been evaluated. Objective: To compare the rates of miscarriage following invasive procedures only in the case of positive cfDNA test results vs immediate invasive testing procedures (amniocentesis or chorionic villus sampling) in women with pregnancies at high risk of trisomy 21 as identified by first-trimester combined screening. Design, Setting, and Participants: Randomized clinical trial conducted from April 8, 2014, to April 7, 2016, in 57 centers in France among 2111 women with pregnancies with a risk of trisomy 21 between 1 in 5 and 1 in 250 following combined first-trimester screening. Interventions: Patients were randomized to receive either cfDNA testing followed by invasive testing procedures only when cfDNA tests results were positive (n = 1034) or to receive immediate invasive testing procedures (n = 1017). The cfDNA testing was performed using an in-house validated method based on next-generation sequencing. Main Outcomes and Measures: The primary outcome was number of miscarriages before 24 weeks' gestation. Secondary outcomes included cfDNA testing detection rate for trisomy 21. The primary outcome underwent 1-sided testing; secondary outcomes underwent 2-sided testing. Results: Among 2051 women who were randomized and analyzed (mean age, 36.3 [SD, 5.0] years), 1997 (97.4%) completed the trial. The miscarriage rate was not significantly different between groups at 8 (0.8%) vs 8 (0.8%), for a risk difference of -0.03% (1-sided 95% CI, -0.68% to ∞; P = .47). The cfDNA detection rate for trisomy 21 was 100% (95% CI, 87.2%-100%). Conclusions and Relevance: Among women with pregnancies at high risk of trisomy 21, offering cfDNA screening, followed by invasive testing if cfDNA test results were positive, compared with invasive testing procedures alone, did not result in a significant reduction in miscarriage before 24 weeks. The study may have been underpowered to detect clinically important differences in miscarriage rates. Trial Registration: ClinicalTrials.gov Identifier: NCT02127515.

Comparison of the Quality of Pediatric Randomized Controlled Trials Published in Both Nursing and Medical Journals: Adherence to the CONSORT Statement.

BACKGROUND: Nursing care should be based on scientific evidence. However, studies must be performed rigorously with accurate reporting for their findings to be applicable to practice. Since the body of scientific nursing literature is broad, the quality and validity of its findings should be regularly controlled and verified to ensure their application and their practical impact. PURPOSE: To compare reporting quality of pediatric randomized controlled trial (RCT) articles in nursing and medical journals. METHODS: Randomly selected articles were reviewed and scored to assess the number of CONSORT items that were adequately reported, generating a CONSORT score. The CONSORT scores for 28 items were compared between the two journal types. RESULTS AND DISCUSSION: The CONSORT scores by journal type were not significantly different: (19.2 [16.2; 22] for medical journals and 19.5 [16.1; 21.5] for nursing journals, p = .77). The reporting of CONSORT items was poor for both journal types. However, there were two significant differences: item 19 (Declaration of all important harm or unintended effects, p = .0006) and item 23 (Registration number of the study, p = .0003), were reported more often in medical journals. The adherence of journals to the CONSORT statement and large sample size was associated with better quality of the reporting of studies. CONCLUSIONS: Based on reporting quality, nursing studies have the same scientific credibility and rigor as medical studies in the pediatric field. LINKING EVIDENCE TO ACTION: The findings of this study could help researchers improve the reporting of their studies and highlight the importance of reporting quality for future knowledge transfer and practical use. The quality of research and its reporting is necessary to improve knowledge transfer into practice.

Chronic Granulomatous Disease in Patients Reaching Adulthood: A Nationwide Study in France.

Background: Although prognosis of Chronic Granulomatous Disease (CGD) has greatly improved, few studies have focused on its long-term outcome. We studied the clinical course and sequelae of CGD patients diagnosed before age 16, at various adult time points. Method: Cross-sectional French nationwide retrospective study of patients screened through the National Reference Center for Primary Immunodeficiencies (CEREDIH) registry. Results: Eighty CGD patients (71 males [88.7%], 59 X-linked [73.7%], median age 23.9 years [minimum, 16.6; maximum, 59.9]) were included, Median ages at diagnosis and last follow-up were 2.52 and 23.9 years, respectively. Seven patients underwent hematopoietic stem cell transplantation. A total of 553 infections requiring hospitalization occurred in 2017 patient-years. The most common site of infection was pulmonary (31%). Aspergillus spp. (17%) and Staphylococcus aureus (10.7%) were the commonest pathogens. A total of 224 inflammatory episodes occurred in 71 patients, mainly digestive (50%). Their characteristics as well as their annual frequency did not vary before and after age 16. Main sequelae were a small adult height and weight and mild chronic restrictive respiratory failure. At age 16, only 53% of patients were in high school. After age 30 years, 9/13 patients were working. Ten patients died during adulthood. Conclusions: Adult CGD patients displayed similar characteristics and rates of severe infections and inflammatory episodes that those of childhood. The high rate of handicap has become a matter of medical and social consideration. Careful follow-up in centers of expertise is strongly recommended and an extended indication of curative treatment by HSCT should be considered.

Long-term efficacy and safety of cladribine (2-CdA) in adult patients with mastocytosis.

Mastocytosis (M) is a clonal myeloid-disabling disorder for which no curative therapy is currently available. Cladribine (2-chlorodeoxyadenosine [2-CdA]) is a synthetic purine analog cytoreductive treatment, for which efficacy is mostly reported in advanced M. Here we report, with a long-term follow-up period (>10 years) efficacy and safety in 68 adult patients with M (36 [53%] had indolent M and 32 [47%] had advanced M) treated by 2-CdA (0.14 mg/kg in infusion or subcutaneously, days 1-5; repeated at 4-12 weeks until 1 to 9 courses). Median 2-CdA courses number was 3.7 (1-9). The overall response rate was 72% (complete remission [R]/major/partial R: 0%/47%/25%) and according to indolent/advanced M was 92% (major/partial R: 56%/36%) and 50% (major/partial R: 37.5%/12.5%), respectively. Clinical improvement was observed for 10 of 11 mediator release and 6 of 7 mast cell infiltration-related symptoms including urticaria pigmentosa and organomegaly (P < .02). Serum tryptase levels decreased (P = .01). Median durations of response were 3.71 (0.1-8) and 2.47 (0.5-8.6) years for indolent and aggressive M, respectively. The most frequent grade 3/4 toxicities were lymphopenia (82%), neutropenia (47%), and opportunistic infections (13%). 2-CdA appears to provide a significant efficacy with some toxicity in various M subtypes, mostly in indolent M, refractory to multiple symptomatic therapies.

Diabetes knowledge in adolescents with type 1 diabetes and their parents and glycemic control.

OBJECTIVE: To evaluate diabetes knowledge and skills (DKS) in adolescents (>10 year) with type 1 diabetes (T1D) and their parents, and its effect on glycemic control. METHODS: A ready-to-use program and a standardized questionnaire comprising 50 true-false questions based on this program, were elaborated by a National Committee, to help dispensing education at diagnosis of T1D. The questionnaire was completed by 2933 T1D patients (49% girls, 51% boys; 14.1 ± 2.5 year), 2180 mothers and 798 fathers, in 115 pediatric centers. Associations between DKS score (number of correct answers), glycated hemoglobin (HbA1c) and sociofamilial characteristics were assessed. RESULTS: DKS score increased with age, and was higher in girls than in boys and in mothers than in fathers; it correlated strongly between adolescents and their own parents; it was higher when adolescents had previously participated in diabetes camp and when parents had higher academic levels. HbA1c decreased significantly with parents' higher DKS score and academic level, and when both parents lived together. Mean adolescent DKS score was significantly higher in patients with HbA1c below 8% or 8.5% than for patients with HbA1c above these thresholds. CONCLUSION: A large survey in T1D children and adolescents and their parents showed associations between DKS and glycemic control, and the major role of sociofamilial factors.

Recurrence of Solid Pseudopapillary Neoplasms of the Pancreas: Results of a Nationwide Study of Risk Factors and Treatment Modalities.

BACKGROUND: Solid pseudopapillary neoplasms of the pancreas (SPPN) can relapse very late, but little is known about risk factors for recurrence and optimal treatment. We aimed to identify risk factors for recurrence and to analyze treatment modalities in all French pediatric cases of SPPN over the past 20 years. MATERIAL AND METHODS: Data were collected from pediatric oncologists and surgeons, and also from adult pancreatic surgeons in order to identify late recurrences. RESULTS: Fifty-one patients (41 girls) were identified. Median age at diagnosis was 13.1 years [8.7-17.9]. Abdominal pain was the commonest presenting symptom (32/49, 65%). The tumor was located in the pancreatic head in 24 patients (47%). Preoperative biopsy or cytology was performed in 14 cases (28%). All patients were operated with a median of 23 days [0-163] after diagnosis. The rate of postoperative morbidity was 29%. With a median follow-up of 65 months [0.3-221], the overall and event-free survival was 100% and 71%, respectively. Seven patients (13.7%) relapsed with a median of 43 months [33-94] after initial surgery. Six were treated surgically, either alone (n = 3) or with perioperative chemotherapy (n = 2) or hyperthermic intraperitoneal chemotherapy (n = 1). One patient in whom further treatment was not feasible was still alive at last news. Risk factors for recurrence were positive surgical margins (P = 0.03) and age less than 13.5 years at diagnosis (P = 0.03). CONCLUSIONS: SPPN recurrence in this pediatric series was a rare and late event that did not undermine overall survival. Complete surgical removal of recurrent tumors appears to be the best option.

Weaning Off Prognosis Factors of Home Parenteral Nutrition for Children With Primary Digestive Disease.

OBJECTIVES: The aim of the present study was to describe the indications for home parenteral nutrition (HPN) in children with primary digestive diseases and to identify factors associated with weaning off. METHODS: All the children initially discharged on HPN between January 1, 2000, and December 31, 2009, for chronic intestinal failure (IF) were included. The associations between clinical factors and weaning off of HPN were assessed using a multivariable Cox regression model. RESULTS: Among the 151 children (boys = 58%) included in this study, 98 (65%) presented with short bowel syndrome (SBS), 17 (11%) with digestive neuromuscular disorders, 14 (9%) with mucosal diseases, 13 (9%) with inflammatory bowel disease, and 9 (6%) with other primary digestive diseases. The probability of survival was ∼100%. At the end of the follow-up, the probability for weaning off of HPN was 0.73 (95% confidence interval 0.54-0.84) but varied according to the underlying cause of IF (for example, SBS and inflammatory bowel disease had a better prognosis). The median time until weaning off was 21 months (95% confidence interval 18-38 months). Unfavourable prognostic factors for weaning off of HPN included a bowel remnant of <40 cm, the presence of <50% of the colon, and daily lipid intakes >1.5 g · kg · day. Underlying disease was also associated with weaning off. CONCLUSIONS: HPN is a safe therapeutic option for children with chronic IF requiring long-term nutritional management. Prognostic factors for weaning off of HPN were identified, and they highlight the relevance of SBS anatomy and parenteral nutrition caloric intake. The outcome of children on HPN was primarily dependent on the underlying disease.
