Risk factors for unexpected infant death among very premature infants in France.

BACKGROUND: Prematurity is one of the risk factors for sudden unexpected infant death (SUID), a phenomenon that remains poorly explained. MATERIALS AND METHODS: The analysis of specific factors associated with SUID among very premature infants (VPI) was performed through a retrospective review of data collected in the French SUID registry from May 2015 to December 2018. The factors associated with SUID among VPI were compared with those observed among full-term infants (FTI). Results are expressed as means (standard deviation [SD]) or medians (interquartile range [IQR)]. RESULTS: During the study period, 719 cases of SUID were included in the registry, 36 (incidence: 0.60 ‰) of which involved VPI (gestational age: 29.2 [2] weeks, 1157 [364]) g] and 313 (0.18 ‰) involved FTI (gestational age: 40 [0.8] weeks, 3298 [452] g). The infants' postnatal age at the time of death was similar in the two groups: 15.5 (12.2-21.8) vs. 14.5 (7.1-23.4) weeks. We observed low breastfeeding rates and a high proportion of fathers with no occupation or unemployment status among the VPI compared to the FTI group (31% vs. 55 %, p = 0.01 and 32% vs. 13 %, p = 0.05, respectively). Among the VPI, only 52 % were in supine position, and 29 % were lying prone at the time of the SUID (compared to 63 % and 17 %, respectively, in the FTI group). CONCLUSION: This study confirms prematurity as a risk factor for SUID with no difference in the SUID-specific risk factors studied except for breastfeeding and socioeconomic status of the fathers. VPI and FTI died at similar chronological ages with a high proportion of infants dying in prone position. These results argue for reinforcement of prevention strategies in cases of prematurity.

Dysmenorrhea among 12-year-old teenagers from different socioeconomic backgrounds.

BACKGROUND: The age of menarche has been gradually declining since the end of the 20th century. Few studies have been carried out about dysmenorrhea in Europe and they mainly included girls over the age of 15 years. METHODS: We conducted an observational study among sixth-grade schoolgirls (usually 11-12 years) during the 2020 academic year in 72 randomly selected public schools in a French region (approval number #20.94). RESULTS: Among 1712 girls interviewed, 257 (23 %) had reached menarche. Overall, 83 % of these teenagers had dysmenorrhea. Symptoms were reported to occur since the first periods in 59 % of the girls. School absenteeism was positively correlated with severe abdominal pain (p = 0.001). Median age at menarche was 11 years (10.7-11.5). Periods lasted less than 3 days, 3-8 days, and more than 8 days in, respectively, 18 %, 70 %, and 7 % of the girls. Symptoms were significantly more frequent and more severe in the urban group than the rural group (p = 0.005). Symptoms were abdominal pain (70 %), fatigue (48 %), difficulty in concentrating (26 %), headache (25 %), digestive disorders (16 %), and breast discomfort (11 %). Of the girls with dysmenorrhea, 61 % took painkillers; 10 % were uncomfortable despite taking painkillers. Sport exemption was more frequent in the urban group (p = 0.003) and among girls with severe abdominal pain (p = 0.001). CONCLUSIONS: The duration of the menstrual cycle was similar between the various socioeconomic groups, but symptoms and ways of coping were significantly different. Dysmenorrhea is definitely an issue that has to be raised with teenagers as soon as menarche occurs or even before that. Easy access to skilled health practitioners should be widespread.

Association of preoperative Enzian score with postoperative fertility in patients with deep pelvic endometriosis.

INTRODUCTION: Endometriosis is a chronic inflammatory disease with a negative impact on fertility. The Enzian classification provides a precise description of deep pelvic endometriotic lesions, especially in the retroperitoneal area, from preoperative pelvic MRI scans. However, it is not known if it is correlated with postoperative fertility. STUDY OBJECTIVE: To determine if there is an association between the preoperative Enzian score and postoperative fertility after deep pelvic endometriosis surgery. DESIGN: We conducted a descriptive, retrospective study using information from the ENDOREN database. SETTING: This was a retrospective study at the Department of Obstetrics and Gynecology at Rennes University Hospital (France) from January 2013 to May 2019 PATIENTS AND INTERVENTIONS: We used information from the ENDOREN database that included all women who underwent surgery for deep endometriosis and wish to conceive. This surgery was intended in a view to achieve a complete removal of endometriosis. MEASUREMENTS: The Enzian score was calculated from preoperative MRI scans, and total, spontaneous, and after In Vitro fertilization (IVF) live births and pregnancies outcomes were collected from the patients'computerized medical records. Univariate and multivariate analysis was performed. RESULTS: Sixty-eight patients were included. The live-birth rate was 35% (24/68). According to the Enzian classification, 25 patients (35%) were classified in compartment A, 64 patients (94%) in compartment B, and 27 (40%) in compartment C. In multivariate analysis, positive predictor of live birth was single Enzian B score (OR=4.7[1.21; 18.81], p = 0.03), negative predictors were uterine adenomyosis and a history of endometriosis surgery. In multivariate analysis, positive predictor of spontaneous live birth was EFI score ≥7 (OR =22.434; CI [1.138; 442.190]). In multivariate analysis, positive predictor was Enzian A score (OR=15.9[2.2; 114.7], p = 0.006), and negative predictors was uterine adenomyosis and Enzian B score (OR=0.01[0; 0.495], p = 0.02) for live birth after IVF. CONCLUSION: The present retrospective study cannot strongly conclude about fertility and correlation with Enzian score because the groups are too small. However, it seems that when solely the compartment B is involved by endometriosis, complete full removal of endometriosis leads to better post-operative live births results. Other studies must be done to determine if Enzian classification based on preoperative pelvic MRI could be clinical value in the decision-making strategy for managing infertile patients with deep pelvic endometriosis.

Performance of finger systolic blood pressure measurement to detect digital occlusive arterial disease in systemic sclerosis.

OBJECTIVE: Digital ulcers related to digital occlusive arterial disease (DOAD) are frequent in patients with SSc. Finger systolic blood pressure (FSBP) and digital-brachial pressure index (DBI) using laser Doppler flowmetry constitute a non-invasive means of detecting DOAD in SSc, although thresholds have yet to be established for defining DOAD. The purpose of this study was to ascertain FSBP and DBI thresholds to detect DOAD in SSc patients. The intra/interday reproducibility of curve reading by four vascular physicians in relation to finger pressure measurement was also investigated. METHODS: SSc patients were followed in this single-centre study (Rennes University Hospital, France) between November 2017 and October 2019.These patients underwent tests before and after heating at two visits spaced 10 days apart. DOAD was diagnosed on the basis of post-warming skin blood flow of ≤206 arbitrary units measured by laser Doppler flowmetry, contingent on previous results validated by arteriography as a gold standard. An interday kappa coefficient with a 95% confidence interval was used to assess reproducibility. RESULTS: Sixteen [10 females; mean age: 63 (9) years] SSc patients were included. Mean time interval between visits was 9 (5) days. The best FSBP threshold for DOAD diagnosis was 76 mmHg and DBI was 0.74 after warming. FSBP and DBI sensitivity/specificity were 59.1% (95% CI: 49.6, 68.5%)/92.5% (95% CI: 85.3, 99.6%) and 73.3% (95% CI: 64.9, 81.8%)/83.0% (95% CI: 72.9, 93.1%), respectively. Intra/interday reproducibility ranged from fair to good. CONCLUSION: The conclusions drawn from this study suggest that FSBP ≤ 76 mmHg and DBI ≤ 0.74 thresholds are potentially reliable indicators of DOAD and demonstrate fair to good intra- and interday reproducibility.

Food addiction among morbidly obese patients: prevalence and links with obesity complications.

Background: In the context of obesity, little is known about the prevalence of food addiction nor about the phenotype of obese patients with food addiction. Objectives: To assess: (i) the prevalence of food addiction among obese patients eligible for obesity surgery; (ii) the relationship between clinical features and the complications of obesity. Methods: Consecutive patients consulting for the first time were included. The Yale Food Addiction Scale (YFAS) 2.0 questionnaire was used to diagnose food addiction and its severity. Demographics, clinical features, and obesity complications were systematically collected. Statistics: Student's test was used for numerical variables and Chi-square test or Fisher's exact test for categorical variables. Results: A total of 292 patients were included: 79% female, age (mean ± SD) 42.6 ± 13.0 yrs., body mass index (BMI) 43.2 ± 6.8 kg/m2. One hundred and eight patients (37%) had food addiction: 58% severe, 33% moderate, 9% mild. Food addiction prevalence was 39% (n = 61/156) among patients eligible for obesity surgery. Food addiction was more frequent among the unemployed, compared to professionally active patients (41.0% vs. 33.5%, p = 0.046). Clinical and metabolic phenotypes and obesity complications were similar between patients with and without food addiction. Conclusion: Food addiction was present in 37% of obese patients, but was not associated with clinical features or obesity complications. Therefore, it should be systemically assessed for appropriate management.

Assessment of Inflammation and Calcification in Pseudoxanthoma Elasticum Arteries and Skin with 18F-FluroDeoxyGlucose and 18F-Sodium Fluoride Positron Emission Tomography/Computed Tomography Imaging: The GOCAPXE Trial.

BACKGROUND: Pseudoxanthoma elasticum (PXE) is an inherited metabolic disease characterized by elastic fiber fragmentation and ectopic calcification. There is growing evidence that vascular calcification is associated with inflammatory status and is enhanced by inflammatory cytokines. Since PXE has never been considered as an inflammatory condition, no incidence of chronic inflammation leading to calcification in PXE has been reported and should be investigated. In atherosclerosis and aortic stenosis, positron emission tomography combined with computed tomographic (PET-CT) imaging has demonstrated a correlation between inflammation and calcification. The purpose of this study was to assess skin/artery inflammation and calcification in PXE patients. Methods: 18F-FluroDeoxyGlucose (18F-FDG) and 18F-Sodium Fluoride (18F-NaF) PET-CT, CT-imaging and Pulse wave velocity (PWV) were used to determine skin/vascular inflammation, tissue calcification, arterial calcium score (CS) and stiffness, respectively. In addition, inorganic pyrophosphate, high-sensitive C-reactive protein and cytokines plasma levels were monitored. RESULTS: In 23 PXE patients, assessment of inflammation revealed significant 18F-FDG uptake in diseased skin areas contrary to normal regions, and exclusively in the proximal aorta contrary to the popliteal arteries. There was no correlation between 18F-FDG uptake and PWV in the aortic wall. Assessment of calcification demonstrated significant 18F-NaF uptake in diseased skin regions and in the proximal aorta and femoral arteries. 18F-NaF wall uptake correlated with CS in the femoral arteries, and aortic wall PWV. Multivariate analysis indicated that aortic wall 18F-NaF uptake is associated with diastolic blood pressure. There was no significant correlation between 18F-FDG and 18F-NaF uptake in any of the artery walls. CONCLUSION: In the present cross-sectional study, inflammation and calcification were not correlated. PXE would appear to more closely resemble a chronic disease model of ectopic calcification than an inflammatory condition. To assess early ectopic calcification in PXE patients, 18F-NaF-PET-CT may be more relevant than CT imaging. It potentially constitutes a biomarker for disease-modifying anti-calcifying drug assessment in PXE.

Effect of Continuous versus Intermittent Subglottic Suctioning on Tracheal Mucosa by the Mallinckrodt TaperGuard Evac Oral Tracheal Tube in Intensive Care Unit Ventilated Patients: A Prospective Randomized Study.

BACKGROUND AND AIMS: A risk of tracheal mucosa injury induced by subglottic suctioning has been raised. Therefore, this prospective randomized study aims to compare the effect of continuous suctioning of subglottic secretions versus intermittent suctioning of subglottic secretions (CSSS vs. ISSS) secretions on tracheal mucosa in front of the suctioning port of the endotracheal tube. PATIENTS AND METHODS: Patients requiring intubation or reintubation in Intensive Care Unit with an expected ventilation duration > 24 h were eligible. Participants received CSSS at -20 mmHg or ISSS at -100 mmHg during 15 s and no suction during 8 s. The effect on tracheal mucosa in front of the suction port was assessed after intubation (T0) and before extubation (T1) using bronchoscopy. Tracheal mucosa damages were graded into five categories (no injury, erythema, edema, ulceration, or necrosis). The occurrence (no injury observed at T0 but present at T1) or the worsening (injury observed at T0 exacerbating at T1) was studied. RESULTS: Seventy-three patients were included and 53 patients (CSSS, n = 26 and ISSS, n = 27) were evaluable on the primary endpoint. The occurrence or worsening of tracheal mucosal damages did not differ between the two groups (CSSS, n = 7 [27%] vs. ISSS, n = 5 [17%], P = 0.465). Daily average volume of suctioned secretion was higher with ISSS (74 ± 100 ml vs. 20 ± 25 ml, P < 0.001). Impossibility to aspirate was higher with CSSS (0.14 ± 0.16 per day vs. 0.03 ± 0.07 per day, P < 0.001). CONCLUSIONS: Our results suggest that tracheal mucosal damages did not differ between CSSS and ISSS. The aspirated volume was higher and impossibility to aspirate was lower with ISSS.
