RESUMEN
BACKGROUND: Obesity is a risk factor for dyspnea. However, investigations of daily living obesity-related dyspnea are limited and its mechanisms remain unclear. We conducted a cross-sectional study to analyze the relationships between dyspnea in daily living, lung function, and body composition in patients with obesity. METHODS: One-hundred and thirty patients (103 women/27 men), candidate for bariatric surgery, with a mean ± SD Body Mass Index (BMI) of 44.8 ± 6.8 kg/m2 were included. Dyspnea was assessed by the modified Medical Research Council (mMRC) scale. Comorbidities, laboratory parameters, pulmonary function tests, arterial blood gases, six-minute walk test (6MWT), handgrip strength, and DXA body composition were analyzed. RESULTS: Thirty-one percent of patients exhibited disabling dyspnea in daily living (mMRC ≥ 2). Compared with patients without disabling dyspnea (mMRC < 2), significant dyspnea (mMRC ≥ 2) was associated with a lower 6MWT distance (395 ± 103 m vs 457 ± 73 m, p < 0.001), lower lung volumes including Expiratory Reserve Volume (42 ± 28% vs 54 ± 27%, p = 0.024), Vital Capacity (95 ± 14 vs 106 ± 15%, p < 0.001) and Forced expiratory volume in one second (95 ± 13 vs 105 ± 15%, p = 0.002), a higher BMI (48.2 ± 7.7 vs 43.2 ± 5.7 kg/m2, p = 0.001) and a higher percentage of fat mass in the trunk (46 ± 5 vs 44 ± 5 p = 0.012) and android region (52 ± 4 vs 51 ± 4%, p = 0.024). There was no difference regarding comorbidities (except hypertension), laboratory parameters, and sarcopenia markers between patients with (mMRC ≥ 2) and without (mMRC < 2) disabling dyspnea. CONCLUSION: Dyspnea in patients with obesity is associated with a reduction in lung volumes and a higher percentage of fat mass in central body regions. How dyspnea and body composition may change with interventions like physical activity or bariatric surgery remains to be investigated.

OBJECTIVE: Pregnancy in patients with macroprolactinomas has been associated with a higher risk of pituitary tumour growth. However, the incidence and risk factors remain unclear. We aimed to evaluate the evolution of macroprolactinomas during pregnancy and to identify potential risk factors. DESIGN, PATIENTS AND MEASUREMENTS: This is a two-centre, retrospective, observational study. All patients with macroprolactinomas, treated with a dopamine receptor agonist (DA), and who had at least one pregnancy were included. RESULTS: There were a total of 85 viable pregnancies in 46 patients with macroprolactinomas. At diagnosis, mean size of pituitary adenomas was 17.9 ± 8.2 mm (10-43 mm) and mean plasma prolactin level was 1012.2 ± 1606.1 µg/L (60-7804 µg/L). Tumour growth-related symptoms were identified 12 times in 9 patients (19.6%) including 3 cases of apoplexy. Restarting, changing and/or increasing DA treatment was effective in 10 cases. Emergency surgery had to be performed twice (due to pituitary apoplexy). Patients with tumour progression tended to present with larger tumours after initial treatment and before pregnancy (9.9 vs 5.9 mm; P = .0504 and 11.5 vs 7.3 mm; P = .0671, respectively), whereas adenoma size at diagnosis did not seem to be a significant factor. The obstetrical outcomes were comparable to the general population. CONCLUSIONS: Symptomatic growth of macroprolactinoma during pregnancy occurred in 19.6% of medically treated patients. This risk seems higher for patients with poor initial tumour response to the DA treatment. Tumour progression is generally well controlled with medical treatment during pregnancy.

BACKGROUND: Evaluation of health-related quality of life (HRQoL) in patients with Alzheimer's disease (AD) is necessary to ensure optimal management. Several scales for assessing HRQoL of patients with AD exist, in particular the Quality of Life in Alzheimer's Disease (QoL-AD), which includes an evaluation by the caregiver of the patient's HRQoL. The aim of this study was to identify factors associated with patient, caregiver and overall HRQoL as assessed by the QoL-AD. METHODS: Cross-sectional multicenter study in subjects aged 65 years and older, with mild to moderate AD. HRQoL scores from the QoL-AD were recorded (3 scores, corresponding to patient, caregiver and overall), as well as sociodemographic variables for the patient and the caregiver, and data from the geriatric cognitive assessment (cognitive, psycho-behavioral, functional evaluations). Caregiver burden was evaluated using the Zarit caregiver burden scale. Factors associated with each QoL-AD score were identified by multivariate linear regression using t-tests and ß estimations. Study was registered in Clinical Trial.gov (NCT02814773). RESULTS: In total, 123 patients with AD were included. For the patient QoL-AD evaluation, depression was significantly associated with lower HRQoL (ß = - 2.56 ± 1.28, p = 0.04), while polypharmacy (ß = - 1.80 ± 0.99, p = 0.07) and anxiety (ß = - 1.70 ± 1.01, p = 0.09) tended to be associated with lower HRQoL scores. In terms of caregiver evaluations, depression (ß = - 3.46 ± 1.09, p = 0.002), polypharmacy (ß = - 1.91 ± 0.92, p = 0.04) and the presence of caregiver burden (ß = - 3.50 ± 0.91, p = 0.0002) were associated with lower HRQoL. For the overall evaluation, depression (ß = - 3.26 ± 1.02, p = 0.002) and polypharmacy (ß = - 1.85 ± 0.81, p = 0.03) were significantly related to lower HRQoL. CONCLUSIONS: Depression and polypharmacy were two factors influencing HRQoL in patients with AD, both by patient self-report and on the caregiver report. Thus, despite the discrepancies between HRQoL as assessed by patients with AD and HRQoL as assessed by their caregiver, the caregiver's assessment may be used to guide patient management when the patient can no longer complete QoL evaluations. Moreover, the association between caregiver burden and the caregiver's QoL-AD score underlines the need to take caregivers into consideration in the overall management of the AD patient.

OBJECTIVE: In clinical research, the recourse to a staff dedicated as CRA with the investigator is common practice to facilitate the work of collection and limiting the missing data (MD). We, therefore, looked for the interest of the recourse of such personnel to data collection. METHODS: MD were classified according to five categories: clinical, para-clinical, treatment, adverse events (serious) and others. Studies were separated in two designs, one-off studies during a single visit (so-called "no follow") and studies on the duration and including several visits (say "with follow"). Similarly, studies were differentiated according to their type of collection "Without ARC" if the data were collected by an investigator, and studies "With ARC". RESULTS: The presence of a CRA can reduce the number of MD whatever their type (Student test: P<0.0001): With CRA mean of MD is 4.8%±8.4% and Without CRA mean of MD is 22.1%±17.0%. CONCLUSION: The delegation of data collection to a staff dedicated reduces significantly the percentage of missing data.

Background: Carbapenems are frequently used as a last resort to treat infections caused by multidrug-resistant Gram-negative organisms, thus carbapenem-non-susceptible Enterobacteriaceae (CNSE) is an emerging health threat. Objectives: To assess risk factors and outcomes of CNSE carriage. Patients and methods: We conducted a matched case-control study in six hospitals in North-Eastern France. The controls were patients harbouring carbapenem-susceptible Enterobacteriaceae. Fifty-five cases and 110 controls were included. Results: Most of the CNSE isolates were Enterobacter cloacae and Klebsiella pneumoniae . Carbapenemase production was observed in 40% of isolates and they produced OXA-48 only. CNSE carriage was significantly associated with recent antibiotic use ( P = 0.014), particularly carbapenems ( P = 0.03) and fluoroquinolones ( P = 0.016). A multivariate analysis using conditional logistic regression showed that the presence of concomitant infection(s) (OR: 9.83; 95% CI 3.04-21.39, P = 0.0031), nosocomial infections (OR: 7.84; 95% CI 2.00-12.54, P = 0.0063) and a high age (OR: 1.07; 95% CI 1.01-1.06, P = 0.038) were independently associated with CNSE carriage. Moreover, patients infected with CNSE had worse outcomes: fewer resolved infections at 1 month ( P = 0.02), and they had a higher mortality rate ( P = 0.0004) and longer hospital stays ( P = 0.02). Conclusions: We identified three independent risk factors for CNSE carriage as well as worse outcomes in infected patients in North-Eastern France. This highlights the importance of early detection of CNSE and the need for antimicrobial therapy re-evaluation after bacteriological analysis has been performed.

AIM: To identify factors associated with health-related quality of life (HRQoL) as assessed by the Dementia Quality of Life (DQoL) in patients with Alzheimer's disease (AD), focusing particularly on functional alterations. METHODS: Cross-sectional multicenter study in subjects aged 65 years or older with mild to moderate AD. HRQoL was measured using the DQoL (five domains: self-esteem, positive affect/humor, negative affect, feeling of belonging, and sense of esthetics). Functional alterations were assessed based on activities of daily living (ADLs) and instrumental activities of daily living (IADLs). We also recorded socio-demographic characteristics of the patient and their carer, and comprehensive geriatric assessment including MMSE and psycho-behavioral data (Neuropsychiatric Inventory, Cornell depression score). Factors associated with each domain of the DQol were identified by multivariate linear regression. RESULTS: In total, 123 subjects were included (mean age 82 ± 6 years, 64% women). Two of the five domains of the DQoL were significantly associated with factors based on functional evaluation. The ability to transfer within the home and the ability to use the telephone were associated with an increase in HRQoL in the 'self-esteem' domain (p = 0.02 and 0.05, respectively). Ability to get dressed without assistance was associated with lower HRQoL in the 'negative affect' domain (p = 0.0007). CONCLUSION: Alterations in functional capacity have a significant effect on HRQoL in several domains of the DQoL.

Ceftazidime is a beta-lactam compound that exerts a time-dependent bactericidal effect. Numerous arguments are in favor of continuous administration of ceftazidime, both for reasons of clinical efficacy and to preserve bacteriological mutation. We report a prospective, single-center, parallel-group, randomized, controlled trial comparing two modes of administration of ceftazidime, namely, continuous administration (loading dose of 20 mg/kg of body weight followed by 60 mg/kg/day) versus intermittent administration (20 mg/kg over 30 min every 8 h) in 34 patients with ventilator-associated pneumonia due to Gram-negative bacilli. The study was performed over 48 h with 13 and 18 assessments of serum ceftazidime in the continuous-infusion group (group A) and the intermittent-fusion group (group B), respectively. Bronchoalveolar lavage (BAL) was performed at steady state in both groups at 44 h to determine ceftazidime levels in the epithelial lining fluid. We chose a predefined threshold of 20 mg/liter for serum concentrations of ceftazidime because of ecological conditions in our center. The median time above 20 mg/liter (T>20 mg) was 100% in group A versus 46% in group B. In group A, 14/17 patients had 100% T>20 mg, versus only 1/17 patients in group B. In the epithelial lining fluid, the median concentration of ceftazidime was 12 mg/liter in group A versus 6 mg/liter in group B. A threshold of 8 mg/liter in the epithelial lining fluid was achieved twice as often in group A as in group B. This study of ceftazidime concentrations in the epithelial lining fluid indicates that continuous infusion presents advantages in terms of pharmacodynamics and predictable efficacy in patients presenting ventilator-associated pneumonia.

PURPOSE: To build a questionnaire to assess health-related quality of life (HRQL) in patients suffering from slowly progressive neuromuscular disease (NMD) using item response theory (IRT). METHODS: A pool of 64 items and a validated questionnaire (WHOQOL-BREF) were administered to 159 patients recruited in eight NMD referral centers. Exploratory statistical analysis included methods derived from both IRT and classical test theory. RESULTS: We constructed a questionnaire named QoL-NMD which is composed of two general items and 24 items classified in three domains: (1) "Impact of Physical Symptoms," (2) "Self-perception" and (3) "Activities and Social Participation." Each domain has good psychometric properties (Cronbach's alpha > 0.77, test-retest ICC > 0.81, Loevinger's H > 0.41) and meets IRT assumptions. Comparison with the WHOQOL-BREF enabled assessing similarities and discrepancies with a generic questionnaire. CONCLUSION: This study enabled the development of a new HRQL questionnaire specifically designed for slowly progressive NMD patients. The QoL-NMD is short enough to be used in clinical practice (26 items). The next steps will be to validate QoL-NMD by re-assessing psychometrics in an independent sample of patients and calibrate the IRT scoring system.

OBJECTIVE: The Dementia Quality of Life (DQoL) and the Quality of Life in Alzheimer's Disease (QoL-AD) are the two most widely used dementia-specific QoL instruments in the world. We aimed to compare the psychometric properties of these two instruments and identify which is most adapted to use in geriatric consultations. METHODS: To evaluate the psychometric properties of the French language validation of DQoL and QoL-AD, 123 patients aged 65 years and over suffering from AD (Mini Mental State Examination score ≥10) were recruited in seven French hospitals and one Switzerland hospital. The DQoL comprises 29 items, ranked on a five-point Likert scale and measuring five QoL domains: self-esteem, positive affect, negative affect, feeling of belonging and sense of aesthetics. The QoL-AD contains 13 items giving an overall score ranging from 13 to 52 and evaluating the domains of interpersonal relationships, financial difficulties, physical condition, memory, mood and overall health. RESULTS: Both questionnaires showed adequate reproducibility at 2 weeks interval (intra-class correlation coefficient >0.80), good internal consistency (Cronbach's alpha coefficient >0.70) and good convergent validity with the general health dimension of the Duke Health Profile. The time required to complete the QoL-AD was significantly shorter (p < 0.0001). DQoL had better discriminant capacity (with at least one dimension significant for each subgroup of severity of cognitive decline, dependency, presence of depression or behavioural disorders). CONCLUSIONS: For quick evaluation of QoL during consultations in geriatric care, the QoL-AD is preferable, whereas for the purposes of research and more in-depth evaluation, the DQoL is more suitable.

Background: The role of obesity on dyspnea in chronic obstructive pulmonary disease (COPD) patients remains unclear. We aimed to provide an assessment of dyspnea in COPD patients according to their Body Mass Index (BMI) and to investigate the impact of obesity on dyspnea according to COPD severity. Methods: One hundred and twenty seven COPD patients with BMI ≥ 18.5 kg/m² (63% male, median (interquartile range) post bronchodilator forced expiratory volume of 1 second (post BD FEV1) at 51 (34-66) % pred) were consecutively included. Dyspnea was assessed by mMRC (Modified medical research council) scale. Lung function tests were recorded, and emphysema was quantified on CT-scan (computed tomography-scan). Results: Twenty-five percent of the patients were obese (BMI ≥ 30kg/m²), 66% of patients experienced disabling dyspnea (mMRC ≥ 2). mMRC scores did not differ depending on BMI categories (2 (1-3) for normal weight, 2 (1-3) 1 for overweight and 2 (1-3) for obese patients; p = 0.71). Increased mMRC scores (0-1 versus 2-3 versus 4) were associated with decreased post BD-FEV1 (p < 0.01), higher static lung hyperinflation (inspiratory capacity/total lung capacity (IC/TLC), p < 0.01), reduced DLCO (p < 0.01) and higher emphysema scores (p < 0.01). Obese patients had reduced static lung hyperinflation (IC/TLC p < 0.01) and lower emphysema scores (p < 0.01) than non-obese patients. mMRC score increased with GOLD grades (1-2 versus 3-4) in non-obese patients but not in obese patients, in association with a trend towards reduced static lung hyperinflation and lower emphysema scores. Conclusion: By contrast with non-obese patients, dyspnea did not increase with spirometric GOLD grades in obese patients. This might be explained by a reduced lung hyperinflation related to the mechanical effects of obesity and a less severe emphysema in severe COPD patients with obesity.

Diarrhea is a frequent complication after kidney transplantation, ascribed to adverse effects of the immunosuppressive therapy in case of negative microbiological examination of the stools. The aim of this study was to improve the microbiological diagnosis by implementing molecular tests. Fifty-four severe diarrhea events that occurred in 49 adult kidney transplant recipients from September 2010 to November 2011 were investigated. One or several enteric pathogens were detected in 13 (23%) stool samples using classical microbiological methods versus 39 (72%) for the seven commercially available multiplex PCR assays used retrospectively (P = 0.006). Interestingly, molecular diagnosis identified 15 multiple infections compared to none using classical techniques. The primary pathogens detected were enteropathogenic Escherichia coli (EPEC) (n = 15; 38%), Campylobacter spp. (n = 15; 38%), and Norovirus (n = 14; 36%). Specificities for Campylobacter and Norovirus infection diagnosis were 75 and 100%, respectively, by comparison to reference methods. Based on molecular findings, a cyclosporine-mycophenolate mofetil combination was identified as a risk factor for developing Norovirus-induced diarrhea. Norovirus infections were also responsible for higher weight loss than all the other causes of diarrhea. In samples from asymptomatic immunocompromised and immunocompetent patients, EPEC but not Norovirus and Campylobacter infections were detected at a frequency similar to that observed in symptomatic kidney transplant recipients. In conclusion, molecular tools significantly improved the detection of single and multiple enteric infections by comparison to classical techniques and could quickly become the key element in the management of severe acute diarrhea in transplant recipients.

PURPOSE: The treatment of giant incisional hernia (IH) with loss of domain (LOD, IHLD) is considerably challenging due to technical difficulties and subsequent post-operative complications. These post-operative risks may be anticipated by calculating the abdominal cavity (AC) volume (ACV) and the IH volume (IHV) on the preoperative CT-scans, using the AC and IH dimensions (Tanaka's method) or using tridimensional volumetry (Sabbagh's method). These techniques are often time-consuming and require specific softwares. The aim of the present study was to develop a simple method to rapidly obtain the LOD-ratio on the preoperative CT-Scan. METHODS: The CT-scans (n = 89) of patients with IHLD were retrospectively studied. Several ratios were calculated using different parameters of the AC and the IH, including width, height and depth, the areas (axial and sagittal ellipse, as well as freehand sagittal surface areas) and these were compared with the reference methods of Sabbagh et al. and Tanaka et al. RESULTS: The LOD ratios calculated from the two reference methods gave similar results (ICC = 0.82, p < 0.0001). The new "R-ratios" (Reims-ratios) obtained from the IH and AC surface areas measured using the "freehand ROI" tool on sagittal view or roughly evaluated by an ellipse on axial view showed excellent correlation with both reference ratios (all ICC ≥ 0.71, p < 0.0001). CONCLUSION: The LOD ratio may be quickly obtained by drawing two circles on the pre-operative CT scan ("R ratios") and available on the webpage https://romeo.univ-reims.fr/Rratio/ . This will certainly help surgeons to routinely anticipate the post-operative complications before IHLD repair.

BACKGROUND: One limitation of the endovascular treatment of intracranial aneurysms is aneurysm recanalization. The Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) study is a prospective multicenter cohort study evaluating the factors associated with recanalization after endovascular treatment. METHODS: The current analysis is focused on patients treated by coiling or balloon-assisted coiling (BAC). Postoperative, mid-term vascular imaging, and evolution of aneurysm occlusion were independently evaluated by two neuroradiologists. A 3-grade scale was used for aneurysm occlusion (complete occlusion, neck remnant, and aneurysm remnant) and for occlusion evolution (improved, stable, and worsened). Recanalization was defined as any worsening of aneurysm occlusion. RESULTS: Between December 2013 and May 2015, 16 French neurointerventional departments enrolled 1289 patients. A total of 945 aneurysms in 908 patients were treated with coiling or BAC. The overall rate of aneurysm recanalization at mid-term follow-up was 29.5% (95% CI 26.6% to 32.4%): 28.9% and 30.3% in the coiling and BAC groups, respectively. In multivariate analyses factors independently associated with recanalization were current smoking (36.6% in current smokers vs 24.5% in current non-smokers (OR 1.8 (95% CI 1.3 to 2.4); p=0.0001), ruptured status (31.9% in ruptured aneurysms vs 25.1% in unruptured (OR 1.5 (95% CI 1.1 to 2.1); p=0.006), aneurysm size ≥10 mm (48.8% vs 26.5% in aneurysms <10 mm (OR 2.6 (95% CI 1.8 to 3.9); p<0.0001), wide neck (32.1% vs 25.8% in narrow neck (OR 1.5 (95% CI 1.1 to 2.1); p=0.02), and MCA location (34.3% vs 28.3% in other locations (OR 1.5 (95% CI 1.0 to 2.1); p=0.04). CONCLUSIONS: Several factors are identified by the ARETA study as playing a role in aneurysm recanalization after coiling: current smoking, aneurysm status (ruptured), aneurysm size (≥10 mm), neck size (wide neck), and aneurysm location (middle cerebral artery). This finding has important consequences in clinical practice. TRIAL REGISTRATION NUMBER: URL: http://www. CLINICALTRIALS: gov; Unique Identifier: NCT01942512.

BACKGROUND: The COVID-19 pandemic caused major oncology care pathway disruption. The CAPANCOVID study aimed to evaluate the impact on pancreatic adenocarcinoma (PA) - from diagnosis to treatment - of the reorganisation of the health care system during the first lockdown. METHODS: This multicentre ambispective observational study included 833 patients diagnosed with PA between September 1, 2019 and October 31, 2020 from 13 French centres. Data were compared over three periods defined as before the outbreak of COVID-19, during the first lockdown (March 1 to May 11, 2020) and after lockdown. RESULTS: During the lockdown, mean weekly number of new cases decreased compared with that of pre-pandemic levels (13.2 vs. 10.8, -18.2%; p = 0.63) without rebound in the post-lockdown period (13.2 vs. 12.9, -1.7%; p = 0.97). The number of borderline tumours increased (13.6%-21.7%), whereas the rate of metastatic diseases rate dropped (47.1%-40.3%) (p = 0.046). Time-to-diagnosis and -treatment were not different over periods. Waiting neoadjuvant chemotherapy in resectable tumours was significantly favoured (24.7%-32.6%) compared with upfront surgery (13%-7.8%) (p = 0.013). The use of mFOLFIRINOX preoperative chemotherapy regimen decreased (84.9%-69%; p = 0.044). After lockdown, the number of borderline tumours decreased (21.7%-9.6%) and advanced diseases increased (59.7%-69.8%) (p = 0.046). SARS-CoV-2 infected 39 patients (4.7%) causing 5 deaths (12.8%). CONCLUSION: This cohort study suggests the existence of missing diagnoses and of a shift in disease stage at diagnosis from resectable to advanced diseases with related therapeutic modifications whose prognostic consequences will be known after the planned follow-up.

Extracellular matrix components such as collagens are deposited within the tumor microenvironment at primary and metastatic sites and are recognized to be critical during tumor progression and metastasis development. This study aimed to evaluate the clinical and prognostic impact of Discoidin Domain Receptor 1 (DDR1) expression in colon cancers and its association with a particular molecular and/or morphological profile and to evaluate its potential role as a prognosis biomarker. Immunohistochemical expression of DDR1 was evaluated on 292 colonic adenocarcinomas. DDR1 was highly expressed in 240 (82.2%) adenocarcinomas. High DDR1 immunostaining score was significantly associated, on univariate analysis, with male sex, left tumor location, BRAF wild type status, KRAS mutated status, and Annexin A10 negativity. High DDR1 immunohistochemical expression was associated with shorter event free survival only. Laser capture microdissection analyses revealed that DDR1 mRNA expression was mainly attributable to adenocarcinoma compared to stromal cells. The impact of DDR1 expression on cell invasion was then evaluated by modified Boyden chamber assay using cell types with distinct mutational profiles. The invasion capacity of colon adenocarcinoma is supported by DDR1 expression. Thus, our results showed that DDR1 was highly expressed in most colon adenocarcinomas and appears as an indicator of worse event free survival.
RESUMEN
Posttraumatic reactions are common among mothers of preterm infants and can have a negative influence on their quality of life and lead to interactional difficulties with their baby. Given the possible trajectories of posttraumatic reactions, we hypothesized that prevalences of postpartum posttraumatic reactions at given times underestimate the real amount of mothers experiencing these symptoms within 18 months following delivery. Additionally, we examined whether sociodemographic and clinical characteristics of dyads influence the expression of posttraumatic symptoms among these mothers. A sample of 100 dyads was included in this longitudinal study led by 3 french university hospitals. Preterm infants born before 32 weeks of gestation and their mothers were followed-up over 18 months and attended 5 visits assessing the infants' health conditions and the mothers' psychological state with validated scales. Fifty dyads were retained through the 18 months of the study. The period prevalence of posttraumatic reactions was calculated and a group comparison was conducted to determine their predictive factors. Thirty-six percent of the mothers currently suffered from posttraumatic symptoms 18 months after their preterm delivery. The 18 months period prevalence was 60.4% among all the mothers who participated until the end of the follow-up. There was a statistical link between posttraumatic symptoms and a shorter gestational age at delivery, C-section, and the mother's psychological state of mind at every assessment time. Only a small proportion of mothers were receiving psychological support at 18 months. Preterm mothers are a population at risk of developing a long-lasting postpartum posttraumatic disorder, therefore immediate and delayed systematic screenings for posttraumatic symptoms are strongly recommended to guide at-risk mothers towards appropriate psychological support.

BACKGROUND AND AIMS: Eating rate is associated with BMI and weight gain in various populations, and is a factor modulating the risk of complications after bariatric surgery. The aim of the present study is to determine whether common difficulties to change eating rate in subjects with obesity candidate to bariatric surgery, could be due to more extensive abnormalities in eating behavior. METHODS: A self-administered questionnaire was distributed to 116 consecutive female patients attending a nutrition consultation for obesity in a specialized center in France. This questionnaire explored eating rate (on an analog 10-point analog scale; a score ≥ 7 defines rapid eating), degree of chewing, signs of prandial overeating and scores of emotionality, externality, and restrained eating. RESULTS: Average age of the study population was 38.4 ± 12.7 years. Mean BMI was 45.5 ± 6.7, and eating rate was 6.3 ± 1.8. Rapid eating was present in 50.0% of the population. There was an inverse relationship between eating rate and degree of chewing (r = -0.59, p < 0.0001). The proportion of "rapid eating" patients was significantly higher among those who responded "all the time", "very often" or "often" (63.1%), as compared to "sometimes" or "never" (25.0%) to the question "Do you feel like you eat too much?" (p < 0.0001). There was a significant positive correlation between eating rate and emotional eating score (r = 0.30, p = 0.001) and external eating score (r = 0.30, p = 0.001), but not with restrained eating score. CONCLUSION: These data show that rapid eating, by being potentially associated to emotional eating, must be considered as an important issue in bariatric surgery.

BACKGROUND: Looking for strict normoglycemia in type 1 diabetes increases the risk of hypoglycemia, exposing to hypoglycemia unawareness. It has been shown that the early correction of hypoglycemia can help recovering the perception of hypoglycemia. The purpose of this prospective study was to assess the value of sensor-augmented insulin-pump therapy to treat hypoglycemia unawareness. METHODS: Eleven patients with type 1 diabetes and partial or total hypoglycemia unawareness received sensor-augmented insulin-pump therapy combined to the low blood glucose-suspend feature (Paradigm® Veo™ pump and Enlite® sensors) for three months. RESULTS: Eighty per cent of the patients improved their hypoglycemia unawareness with an increase in the hypoglycemia perception threshold of 31 mg/dL as evaluated by blinded continuous glucose monitoring. These results were correlated to a self-assessment quiz evaluation. Results were sustained at six months (three months after patients stopped using the system). Sensitive neuropathy, untreated hypoglycemia and the area under the curve for hypoglycemia events were associated with less chance of recovery. These devices were globally considered by the patients as simple to use, with no major disadvantages and only a single withdrawal occurred. CONCLUSIONS: Sensor-augmented insulin-pump therapy should be considered as a possible treatment of hypoglycemia unawareness.

OBJECTIVES: Very preterm infants are known to be at risk of developmental disabilities and behavioural disorders. This condition is supposed to alter mother-infant interactions. Here we hypothesize that the parental coping with the very preterm birth may greatly influence mother-infant interactions. METHODS: 100 dyads were included in 3 university hospitals in France. Preterm babies at higher risk of neurodevelopmental sequelae (PRI>10) were excluded to target the maternal determinants of mother-infant interaction. We report the follow-up of this cohort during 1 year after very preterm birth, with regular assessment of infant somatic state, mother psychological state and the assessment of mother-infant interaction at 12 months by validated scales (mPPQ, HADS, EPDS, PRI, DDST and PIPE). RESULTS: We show that the intensity of post-traumatic reaction of the mother 6 months after birth is negatively correlated with the quality of mother-infant interaction at 12 months. Moreover, the anxious and depressive symptoms of the mother 6 and 12 months after birth are also correlated with the quality of mother-infant interaction at 12 months. By contrast, this interaction is not influenced by the initial affective state of the mother in the 2 weeks following birth. In this particular population of infants at low risk of sequelae, we also show that the quality of mother-infant interaction is not correlated with the assessment of the infant in the neonatal period but is correlated with the fine motor skills of the baby 12 months after birth. CONCLUSIONS: This study suggests that mothers' psychological condition has to be monitored during the first year of very preterm infants' follow-up. It also suggests that parental interventions have to be proposed when a post-traumatic, anxious or depressive reaction is suspected.

AIM: To determine predictive factors associated with rapid cognitive decline (RCD) in elderly patients suffering from Alzheimer disease (AD). METHODS: Patients suffering from mild to moderate AD were included. RCD was defined as the loss of at least 3 points on the Mini-Mental State Examination (MMSE) over 12 months. Factors associated with RCD were identified by logistic regression. RESULTS: Among 123 patients included, 61 were followed up until 12 months. RCD occurred in 46% of patients (n = 28). Polymedication (p < 0.0001), the fact that the caregiver was the child or spouse of the patient (p < 0.0001) and autonomy for washing (p < 0.0001) were protective factors against RCD, while the presence of caregiver burden (p < 0.0001) was shown to be a risk factor for RCD. CONCLUSION: Early detection of the RCD risk in AD patients could make it possible to anticipate the patient's medical needs and adjust the care plan for caregiver burden.
