Mental health among university students with eating disorders and irritable bowel syndrome in France.

BACKGROUND: University students are subject to stress due to academic pressure, empowerment and transition from adolescence to adulthood. This young population may have a higher risk of functional disorders as eating disorders (ED) and irritable bowel syndrome (IBS). Our objective was to determine the prevalence of ED, IBS and both and the associated behaviours. METHODS: A cross sectional study was conducted in Rouen University (France). Participating students filled an anonymous self-questionnaire with items on socio-demographics, depression (Duke score), stress (Cohen score), emotional exhaustion (Maslach Inventory), insomnia (Insomnia Severity Index), cyberaddiction (Internet Addiction Test), ED (SCOFF-F test) and IBS (Rome III). RESULTS: This study included 731 students (male/female ratio=0.43). The prevalences of ED, IBS and co-existing ED-IBS were respectively 16.7%, 7.8% and 2.7%. ED and IBS were more common in female students. Depression, stress, emotional exhaustion, insomnia and cyberaddiction were significantly associated with ED and IBS or both. Students with ED had a higher risk of having IBS (Adjusted Odds Ratio (AOR)=2.42, 95% CI: 1.30-4.51), and conversely students with IBS had a higher risk of having ED (AOR=2.46, 95% CI: 1.32-4.55) and were more likely to be in the third year of academic study or above (AOR=2.95, 95% CI: 1.50-5.76). CONCLUSION: Students (female especially) suffer from ED and IBS, with a significant risk of co-existing ED-IBS. ED and IBS are related to multiple mental health symptoms, which could lead to negative academic consequences. Screening, using simple and quick tests as SCOFF questionnaire and ROME IV criteria (update of ROME III in 2016), is essential in this population of university students.

A specific prediction equation is necessary to estimate peak oxygen uptake in obese patients with metabolic syndrome.

PURPOSE: The aims were to: (1) compare peak oxygen uptake ([Formula: see text]peak) predicted from four standard equations to actual [Formula: see text]peak measured from a cardiopulmonary exercise test (CPET) in obese patients with metabolic syndrome (MetS), and (2) develop a new equation to accurately estimate [Formula: see text]peak in obese women with MetS. METHODS: Seventy-five obese patients with MetS performed a CPET. Anthropometric data were also collected for each participant. [Formula: see text]peak was predicted from four prediction equations (from Riddle et al., Hansen et al., Wasserman et al. or Gläser et al.) and then compared with the actual [Formula: see text]peak measured during the CPET. The accuracy of the predictions was determined with the Bland-Altman method. When accuracy was low, a new prediction equation including anthropometric variables was proposed. RESULTS: [Formula: see text]peak predicted from the equation of Wasserman et al. was not significantly different from actual [Formula: see text]peak in women. Moreover, a significant correlation was found between the predicted and actual values (p < 0.001, r = 0.69). In men, no significant difference was noted between actual [Formula: see text]peak and [Formula: see text]peak predicted from the prediction equation of Gläser et al., and these two values were also correlated (p = 0.03, r = 0.44). However, the LoA95% was wide, whatever the prediction equation or gender. Regression analysis suggested a new prediction equation derived from age and height for obese women with MetS. CONCLUSIONS: The methods of Wasserman et al. and Gläser et al. are valid to predict [Formula: see text]peak in obese women and men with MetS, respectively. However, the accuracy of the predictions was low for both methods. Consequently, a new prediction equation including age and height was developed for obese women with MetS. However, new prediction equation remains to develop in obese men with MetS.

Validation of the Arabic version of the SCOFF questionnaire for the screening of eating disorders.

The high prevalence of eating disorders in Arab countries indicates a need for an Arabic language screening tool. This study aimed to validate an Arabic version (A-SCOFF) of the British SCOFF questionnaire, a brief tool for the screening of eating disorders in primary health care. After translation and back-translation the A-SCOFF was given to 123 female patients [mean age 32 (SD 8.8) years] visiting primary health-care centres in Beirut. Each patient was evaluated by an eating disorders specialist blinded to A-SCOFF results. The validated Arabic version of the Mini International Neuropsychiatric Interview and the DSM-IV criteria for eating disorders were used as diagnostic references. The best diagnostic threshold for the A-SCOFF was found to be at 2 positive answers with a sensitivity of 80.0%, a specificity of 72.7% and an area under the curve of 80.0%. The A-SCOFF questionnaire is accurate and reliable for the early detection of eating disorders in this high-risk population.

Is BRAF a prognostic factor in stage III skin melanoma? A retrospective study of 72 patients after positive sentinel lymph node dissection.

BACKGROUND: BRAF was identified as an oncogene in skin melanoma in 2002, and since 2011 has been a therapeutic target in the treatment of metastatic melanoma. The role of BRAF mutation in tumour initiation and the disease course remains to be elucidated. OBJECTIVES: The main objective of our study was to determine whether there is a relationship between BRAF status and overall survival in patients with a melanoma and a positive sentinel lymph node. We also sought an association between BRAF status and the clinicopathological features of the melanoma. Finally, we looked for a potential heterogeneity of BRAF status in primary and metastatic tumours. METHODS: All patients (n = 72) treated for melanoma and with a positive sentinel lymph node at the University Hospital of Clermont-Ferrand, France, between January 2000 and January 2010 were enrolled in the study. We investigated BRAF status in primary melanoma and lymph node metastatic tissue in our molecular pathology laboratory and collected the clinical and survival data. RESULTS: Of the 72 patients, 32 had at least one BRAF mutation. There was a statistically significant difference in overall survival between the BRAF-mutated and wild-type populations. The only clinical feature related to BRAF status was metastatic burden. Of the 25 patients in whom we obtained the status in both locations, five had a discordant result. CONCLUSIONS: BRAF mutation is an indicator of poor prognosis in patients with stage III melanoma with a positive sentinel lymph node. BRAF status could be used in the staging of this population. BRAF has a role not only in cellular immortalization but also in metastatic spread.

Low thoracic skeletal muscle index is associated with negative outcomes in 244 patients with respiratory COVID-19.

BACKGROUND: Sarcopenia is associated with negative outcomes in intensive care unit (ICU) patients and during chronic diseases. We aimed to evaluate if low skeletal muscle index (SMI) measured by computed tomography (CT) at the thoracic level is associated with poor outcomes in hospitalized patients with respiratory COVID-19. METHODS: Patients admitted to the hospital between March 1st and June 9, 2020 with a confirmed diagnosis of respiratory COVID-19 in the Emergency Department were included in this retrospective cohort study. SMI was assessed from a transverse CT image at the T12 level. We analysed the association between thoracic SMI and mortality, ICU admissions, infections, length of stay and gravity scores. RESULTS: We included 244 patients, whose median age was 62 (20-95) years, mean body mass index was 28,6 kg/m2, and 34% were obese patients. 102 patients (41,8%) had low thoracic SMI. On multivariable analysis, low thoracic SMI was associated with more infections (OR = 1,88 [1,06-2,98]) and increased length of stay (OR = 1,87 [1,14-3,49]) but not with mortality (OR = 1.37 [0.54-3.52]), whereas it was inversely associated with ICU admission (OR = 5,56 [1,96-16,67]. CONCLUSION: Low SMI measured by CT at the thoracic level T12 is associated with negative outcomes in patients with respiratory COVID-19.

Desmoplastic malignant melanoma: a study of ten cases and status of BRAF mutation.

BACKGROUND: Desmoplastic malignant melanoma (DM) is a rare variant of melanoma. BRAF gene mutations have been poorly explored in this entity. OBJECTIVE: To detect BRAF gene mutation in a series of DM. METHODS: This is a single-center retrospective study of ten patients with DM, with a biomolecular analysis of BRAF mutation. RESULTS: The male:female ratio was 2.3:1, with a mean patient age of 66.5 years. Melanoma arose in the head and neck region in 3 cases. The mean tumor thickness was 7.97 mm, Clark level was IV or V in all cases. Six melanomas were of the pure DM variant. Three patients had at least one local recurrence, two had regional node metastases, and two experienced systemic metastases which they died of (average follow-up 34.1 months). A V600E BRAF mutation was detected in only one patient. CONCLUSION: BRAF mutation seems to be a rare event in DM contrary to other melanoma variants.

Prenatal diagnosis of lobar bronchial atresia.

We report three cases of fetal lobar bronchial atresia referred to our Fetal Medicine Center during the mid-trimester of pregnancy over the last 15 years. Lobar bronchial atresia can mimic a main stem bronchial atresia on mid-trimester ultrasound examination as it induces extensive lobar enlargement, major mediastinal shift and eversion of the diaphragm. It was associated with severe pulmonary hypoplasia in all three cases, even though polyhydramnios and ascites were absent in two. Termination of pregnancy was performed at parental request after extensive counseling in each of the cases and necropsy confirmed one or two enlarged lung lobes leading to major compression of the remaining lobe(s) of the ipsilateral lung, the contralateral lung and the heart. No other anomalies were observed and the karyotype was normal in all cases.

Genotype-phenotype correlations in fetuses and neonates with autosomal recessive polycystic kidney disease.

The prognosis of autosomal recessive polycystic kidney disease is known to correlate with genotype. The presence of two truncating mutations in the PKHD1 gene encoding the fibrocystin protein is associated with neonatal death while patients who survive have at least one missense mutation. To determine relationships between genotype and renal and hepatic abnormalities we correlated the severity of renal and hepatic histological lesions to the type of PKHD1 mutations in 54 fetuses (medical pregnancy termination) and 20 neonates who died shortly after birth. Within this cohort, 55.5% of the mutations truncated fibrocystin. The severity of cortical collecting duct dilatations, cortical tubule and glomerular lesions, and renal cortical and hepatic portal fibrosis increased with gestational age. Severe genotypes, defined by two truncating mutations, were more frequent in patients of less than 30 weeks gestation compared to older fetuses and neonates. When adjusted to gestational age, the extension of collecting duct dilatation into the cortex and cortical tubule lesions, but not portal fibrosis, was more prevalent in patients with severe than in those with a non-severe genotype. Our results show the presence of two truncating mutations of the PKHD1 gene is associated with the most severe renal forms of prenatally detected autosomal recessive polycystic kidney disease. Their absence, however, does not guarantee survival to the neonatal period.

Beneficial effects of cathepsin inhibition to prevent chemotherapy-induced intestinal mucositis.

One of the main secondary toxic side effects of anti-mitotic agents used to treat cancer patients is intestinal mucositis. Previous data showed that cathepsin D activity, contributing to the proteolytic lysosomal pathway, is up-regulated during intestinal mucositis in rats. At the same time, cathepsin inhibition limits intestinal damage in animal models of inflammatory bowel diseases. The aim of this study was to evaluate the effects of cathepsin inhibition on methotrexate-induced mucositis in rats. Male Sprague-Dawley rats received saline solution subcutaneously as the control group or 2·5 mg/kg of methotrexate for 3 days (D0-D2). From D0 to D3 methotrexate-treated rats also received intraperitoneal injections of pepstatin A, a specific inhibitor of cathepsin D or E64, an inhibitor of cathepsins B, H and L, or vehicle. Rats were euthanized at D4 and jejunal samples were collected. Body weight and food intake were partially preserved in rats receiving E64 compared with rats receiving vehicle or pepstatin A. Cathepsin D activity, used as a marker of lysosomal pathway, was reduced both in E64 and pepstatin-treated rats. However, villus atrophy and intestinal damage observed in methotrexate-treated rats were restored in rats receiving E64 but not in rats receiving pepstatin A. The intramucosal concentration of proinflammatory cytokines, interleukin-1ß and cytokine-induced neutrophil chemoattractant (CINC)-2, was markedly increased in methotrexate-treated rats receiving vehicle or pepstatin A but not after E64 treatment. In conclusion, a large broad inhibition of cathepsins could represent a new potential target to limit the severity of chemotherapy-induced mucositis as opposed to the inhibition of cathepsin D alone.

Quality of life and obesity class relationships.

The aim of this study was to quantify the impact of obesity class on Health-Related Quality Of Life (HRQOL) and Total daily Energy Expenditure (TEE). 69 obese individuals were self-selected to 1 of 3 groups based upon Body Mass Index (BMI). Anthropometric parameters (height, weight, waist and hip circumference, fat mass, lean body mass), biological parameters (high density lipoprotein, low density lipoprotein, triglycerides, glycaemia, total cholesterol), and resting energy expenditure were assessed for each group. The Short Form Health Survey (SF-36) questionnaire and Hospital Anxiety Depression (HAD) scale were used to measure HRQOL, and TEE was estimated by Kurpad's method. Class 3 obesity was associated with greater impairment of the physical aspects of the SF-36 (37.2±11.3), greater depression risk (8.2±4.1), and higher TEE (30.0±7.9 Kcal·day (-1)·kg (-1)) than the lower obesity classes. No difference was observed among the 3 groups in the mental and psychosocial aspects of HRQOL. Impaired physical functioning was correlated with fat mass, age, waist circumference, glycaemia control and bodily pain. TEE was positively correlated with BMI, weight, fat mass and lean body mass. The obesity class had a negative impact on the physical health aspect of HRQOL, depression risk and energy expenditure. These impairments were associated with excess fat mass, waist circumference and glycaemia parameters.

Dietary modulation of peroxisome proliferator-activated receptor gamma.

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor that regulates intestinal inflammation. PPAR gamma is highly expressed in the colon and can be activated by various dietary ligands. A number of fatty acids such as polyunsaturated fatty acids or eicosanoids are considered as endogenous PPAR gamma activators. Nevertheless, other nutrients such as glutamine, spicy food or flavonoids are also able to activate PPAR gamma. As PPAR gamma plays a key role in bacterial induced inflammation, anti-inflammatory properties of probiotics may be mediated through PPAR gamma. The aims of the present review are to discuss of the potential roles of dietary compounds in modulating intestinal inflammation through PPAR gamma.

Ovarian epithelial dysplasia after ovulation induction: time and dose effects.

BACKGROUND: Ovarian epithelial dysplasia was first described after prophylactic oophorectomies for genetic risk. Ovarian stimulation has been considered as a risk factor of ovarian cancer by Fathalla's incessant ovulation theory. In this study, we have investigated the risk of ovarian dysplasia after ovulation induction. METHODS: We reviewed 99 oophorectomies or cystectomies between 1990 and 2005 divided them into two groups: previous in vitro fertilization (n = 37) and a panel of fertile controls (n = 62). Eleven epithelial cytological and architectural features were defined and an ovarian epithelial dysplasia score was calculated to quantify the degree of ovarian epithelial abnormalities. RESULTS: All the ovaries were macroscopically non-cancerous except in two patients (one endometrioid cancer and one borderline tumour). The mean ovarian dysplasia score was significantly higher in the ovulation induction group than in the control group (7.64 versus 3.62, P = 0.0002). We also found a relationship between the number of ovulation-inducted cycles and the severity of ovarian dysplasia ('dose-effect') and a relationship between time after the end of ovulation induction (over 7 years) and the severity of ovarian dysplasia ('time-effect'). CONCLUSIONS: There is probably a relationship between ovarian epithelial dysplasia and either ovulation inducing drugs or infertility. By Fathalla's incessant ovulation theory, 'the dose effect and the time effect' of ovarian stimulation may explain ovarian dysplasia formation.

Weight loss and quality of life after bariatric surgery: a study of 200 patients after vertical gastroplasty or adjustable gastric banding.

BACKGROUND AND OBJECTIVES: Long term evaluation of bariatric surgery must include quality of life measurement. METHODS: Quality of life (QoL) was evaluated using the original Moorehead-Ardelt questionnaire for 200 patients operated for massive obesity in a single centre between 1994 and 2003. QoL and physical data were obtained by retrospective mail questionnaire. Surgical procedures were vertical-banded gastroplasty according to Mason (VBGM) and adjustable gastric banding (AGB) in 61 and 39% of patients, respectively. The aim of the study was to assess the nutritional outcome and QoL according to the procedure. RESULTS: Overall, the body mass index (BMI) decreased from 50+/-8 kg/m(2) before surgery to 35.2+/-7.5 kg/m(2) at the time of the questionnaire. The percentage of weight loss was 28.8+/-12.2%. In the group treated with VBGM, the mean initial weight (P=0.003) and the percentage of weight loss (P<0.001) were significantly higher, and the QoL was better (P=0.003) than in the group treated with AGB. On the basis of the time spent since surgery, a regular weight loss was observed during the first 5 years, whereas weight subsequently increased over the five following years. Similarly, the total QoL score gradually improved during the first 5 years and worsened thereafter. However, it remained better than before surgery. A linear regression analysis showed a positive correlation between the percentage of weight loss and the QoL score (P<0.001). CONCLUSIONS: This study suggests that the bariatric surgery, particularly the VBGM technique, improved the QoL of obese patients, at least in the first 5 years following surgery.

[The use of ultrasonographic 3D power Doppler to describe an ovarian Sertoli-Leydig cell tumor]. / Description échographique d'une tumeur ovarienne de Sertoli-Leydig à l'aide du doppler énergie tridimensionnel.

[Congenital lobar emphysema: a rare etiology of hyperechoic lung]. / Une étiologie rare de poumon hyperéchogène: l'emphysème lobaire géant congénital.

Lobar congenital emphysema is a rare pulmonary malformation corresponding to progressive overinflation of a pulmonary lobe secondary to partial bronchial obstruction. Prenatal diagnosis is mainly based on lung hyperechoic area. Sonographic features are not specific highlighting the interest of fetal MRI or postnatal tomodensitometry. This case report describes prenatal detection including pitfalls and postnatal management.

[Ovarian epithelial dysplasia: myth or reality? Review]. / Dysplasie épithéliale ovarienne: mythe ou réalité? Revue de la littérature.

Ovarian epithelial dysplasia has been described in the ovarian surface epithelium by histologic, morphometric and nuclear profile studies. It could represent a potential precursor of ovarian malignancy in patients with genetic risk of ovarian cancer, although its natural history and progression to carcinoma are unpredictable. Diagnosis and identification of ovarian dysplasia would certainly be useful to understand the early steps of ovarian carcinogenesis. However, dysplasia in relation with ovulation induction seems to have a different pattern. We report dysplasia definitions and the current clinical management.

Changes and specificities in health behaviors among healthcare students over an 8-year period.

BACKGROUND: Healthcare students are future health care providers and serve as role models and coaches to enhance behaviors for healthy lifestyles. However healthcare students face multiple stressors that could lead to adopting risk behaviors. OBJECTIVES: To assess the changes in health risk factors among healthcare students between 2007 and 2015, and to identify specific health behaviors based on the curriculum in a population of healthcare students. METHODS: Two cross sectionnal studies were conducted in 2007 and 2015 among nursing, medical, pharmacy, and physiotherapy students (Rouen, France). During compulsory courses and examination sessions students filled self-administered questionnaires on socio-demographic characteristics and behavior as: tobacco smoking, alcohol consumption, cannabis consumption, eating disorders, regular practice of sport, perceived health, stress and use of psychotropic drugs. RESULTS: 2,605 healthcare students were included (1,326 in 2007 and 1,279 in 2015), comprising 1,225 medical students (47.0%), 738 nursing students (28.3%), 362 pharmacy students (13.9%), and 280 physiotherapy students (10.8%). Between 2007 and 2015, occasional binge drinking and regular practice of sport increased significantly among healthcare students, respectively AOR = 1.48 CI95% (1.20-1.83) and AOR = 1.33 CI95% (1.11-1.60), regular cannabis consumption decreased significantly, AOR = 0.32 CI95% (0.19-0.54). There was no change in smoking or overweight/obese. There was a higher risk of frequent binge drinking and a lower risk of tobacco smoking in all curricula than in nursing students. Medical students practiced sport on a more regular basis, were less overweight/obese, had fewer eating disorders than nursing students. CONCLUSION: Our findings demonstrate a stable frequency of classic behaviors as smoking but a worsening of emerging behaviors as binge drinking among healthcare students between 2007 and 2015. Health behaviors differed according to healthcare curricula and nursing students demonstrated higher risks. As health behaviors are positively related to favorable attitudes towards preventive counseling, therefore healthcare students should receive training in preventive counseling and develop healthy lifestyles targeted according to the health curriculum.

Delayed gastric emptying and altered antrum protein metabolism during activity-based anorexia.

BACKGROUND: Anorexia nervosa, a restrictive eating disorder, is often associated with gastrointestinal disorders, particularly a delayed gastric emptying. However, the mechanisms remained poorly documented. Thus, we aimed to evaluate gastric emptying and antrum protein metabolism in the Activity-Based Anorexia model (ABA). METHODS: Females C57Bl/6 mice were randomized into 3 groups: Control, ABA, and Limited Food Access (LFA). Food access has been progressively limited from 6 h/day at day 6 to 3 h/day at day 9 and until day 17. ABA mice had free access to an activity wheel. Gastric emptying was assessed. On gastric extracts, a proteomic analysis was performed, as well as an evaluation of protein synthesis and protein oxidation. KEY RESULTS: Both LFA and ABA mice exhibited a delayed gastric emptying compared with Controls (P < .05). Proteomic approach revealed 15 proteins that were differentially expressed. Among these proteins, we identified 2 clusters of interest contributing to (i) the organization of muscle fiber with ACTA2, VCL, KRT19, KRT8, and DES proteins and (ii) "heat shock proteins" with STIP1, HSPD1, and HSPA8 proteins. ABA mice specifically exhibited an increased rate of gastric oxidized proteins. CONCLUSIONS AND INFERENCES: Delayed gastric emptying observed in anorectic conditions appears to be secondary to malnutrition. However, an oxidative stress is specifically present in the stomach of ABA mice. Its role remains to be further studied.

[Nodular thrombophlebitis and granulomatous systemic disease]. / Thrombophlébites nodulaires et maladies systémiques granulomateuses.

INTRODUCTION: Nodular thrombophlebitis is septal hypodermitis characterised by vasculitis with vein thrombosis. It may indicate serious underlying disorders. EXEGESIS: We present two cases of nodular superficial phlebitis, which revealed tuberculosis and sarcoidosis. CONCLUSION: Nodular thrombophlebitis are classic during evolution of Behçet disease or Buerger vasculitis. In sarcoidosis, erythema nodosum and granulomatous involvement are the most common cutaneous manifestation. Nodular thrombophlebitis has never been described. Panniculitis are classical in tuberculosis. But most cases are erythema nodosum and cases of erythema induratum of Bazin. Nodular thrombophlebitis could reveal thrombophilic abnormalities, and even more neoplasms especially when they are recurrent and migratory.

[Regression in primary cutaneous melanoma is not predictive for sentinel lymph node micrometastasis]. / Absence de valeur prédictive des signes de régression histologique sur l'envahissement du ganglion sentinelle.

BACKGROUND: The predictive value of regression in melanoma is debated. AIM OF THE STUDY: A retrospective single-centre study to evaluate the correlation between regression in primary skin tumor and the presence of micrometastases in sentinel lymph nodes. PATIENTS AND METHODS: Histological signs of regression in 84 melanomas (>1 mm) with corresponding sentinel lymph nodes were studied by two independent pathologists. RESULTS: Regression was seen in 40 skin melanoma tumors while micrometastasis was seen in 24. Of the tumors with micrometastasis, only 10 were regressive (RR: 0.47, p=0.49). Breslow value>2 mm and male sex were predictive for node micrometastasis (RR: 4.6, p=0.03 and RR: 7.6, p=0.006, respectively). On multivariate analysis, these two factors were independent. COMMENTS: These data suggest that regression in primary cutaneous melanoma is not predictive for lymph node metastasis.
