Long-term trajectories of densely reported depressive symptoms during an extended period of the COVID-19 pandemic in Switzerland: Social worries matter. Compr Psychiatry 2024; 130:152457. [PMID: 38325041 DOI: 10.1016/j.comppsych.2024.152457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 01/04/2024] [Accepted: 01/29/2024] [Indexed: 02/09/2024] Open
Abstract
Previous mental health trajectory studies were mostly limited to the months before access to vaccination. They are not informing on whether public mental health has adapted to the pandemic. The aim of this analysis was to 1) investigate trajectories of monthly reported depressive symptoms from July 2020 to December 2021 in Switzerland, 2) compare average growth trajectories across regions with different stringency phases, and 3) explore the relative impact of self-reported worries related to health, economic and social domains as well as socio-economic indicators on growth trajectories. As part of the population-based Corona Immunitas program of regional, but harmonized, adult cohorts studying the pandemic course and impact, participants repeatedly reported online to the DASS-21 instrument on depressive symptomatology. Trajectories of depressive symptoms were estimated using a latent growth model, specified as a generalised linear mixed model. The time effect was modelled parametrically through a polynomial allowing to estimate trajectories for participants' missing time points. In all regions level and shape of the trajectories mirrored those of the KOF Stringency-Plus Index, which quantifies regional Covid-19 policy stringency. The higher level of average depression in trajectories of those expressing specific worries was most noticeable for the social domain. Younger age, female gender, and low household income went along with higher mean depression score trajectories throughout follow-up. Interventions to promote long-term resilience are an important part of pandemic preparedness, given the observed lack of an adaptation in mental health response to the pandemic even after the availability of vaccines in this high-income context.

Muscle dysmorphia from an addictive perspective: Validation of the Addiction to Body Image Inventory (ABII). L'ENCEPHALE 2024; 50:20-25. [PMID: 36528392 DOI: 10.1016/j.encep.2022.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 10/11/2022] [Accepted: 10/15/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVES Muscle dysmorphia (MD) is a disorder affecting mainly men and is characterized by significant dissatisfaction with muscles. The idea that MD could represent an addiction has been theoretically discussed, but no empirical data are available. Based on Foster et al. (2015) framework, the Addiction to Body Image Inventory (ABII) was developed. This study aims to validate the ABII and to evaluate its capacity to capture MD severity. METHODS A first community sample of 466 participants was recruited and completed the ABII and questionnaires on MD and body esteem. A second sample of 47 men at risk of MD was recruited mostly in gyms and completed the ABII and questionnaires on MD, eating and psychological symptoms. RESULTS With the community sample, the results showed that the ABII had a valid factorial structure, good internal consistency, and good convergent validity. With the sample of men at risk of MD, the results showed that the ABII had good convergent validity with MD and eating symptoms but not with psychological symptoms. The results of a regression model showed that the ABII explained 12% of the MD variance. CONCLUSIONS This study brings the first measure of addiction to body image and suggests that MD must be understood as a complex phenomenon including eating symptoms and addictive tendencies.

Abstract
Cultural Concepts of Distress (CCDs) are culturally constructed diagnostic categories that exist within a specific society or culture. While several studies have assessed CCDs around the world, few studies have examined them in Haiti. This qualitative study examines manifestations of anxiety and depression via "sent spirits" in the form of maladi nanm ("Soul disorder") and maladi zonbi ("Zombie disorder"), and bipolar disorder in the form of maladi lalin ("Moon disorder"). Examples of CCDs were recorded as part of a study which interviewed 96 outpatients at the first mental health center in northern Haiti. Using qualitative methods, the authors identified three specific CCDs as reported by mental health patients. Maladi nanm and maladi zonbi represent alternative explanatory models of anxiety and depression in which the sufferer views mental illness as stemming from a sent spirit, or spirit which is intentionally sent supernaturally with the intent to cause harm. Maladi lalin is experienced by patients with bipolar disorder who associate cycles of mania and depression as in-sync with the phases of the moon. Understanding culture-bound forms of mental distress in settings such as Haiti is essential to developing accurate psychometrics for measuring mental health, as well as ensuring culturally appropriate and effective diagnosis and treatment.

Abstract
This study assesses the perspectives and experiences of Vodou priests (ougan) in the treatment of mental illness in northern Haiti. Our goal is to explore the etiology and popular nosologies of mental illness in the context of Haitian Vodou, through understandings of illness and misfortune which are often viewed as a result of sent spirits-or spirits sent supernaturally by others with the intent to cause harm. Using a qualitative approach, this study conducted semi-structured in-depth interviews with 20 ougan living near the city of Cap-Haïtien. Interviews highlight a sample of healers with little formal training who maintain beliefs and practices that differ significantly from current biomedical models. Ougan treat mental illness through a variety of means including prayer and conjuring of spirits, leaves for teas and baths, as well as combinations of perfumes, rum, human remains, and other powdered concoctions that are either imbibed or rubbed on the skin. The primary purpose of these treatments is to expel the spirit causing harm, yet they can often result in additional harm to the patient. Findings suggest that while ougan are willing to collaborate with biomedical practitioners, significant barriers remain preventing cooperation between these two groups.

Abstract
INTRODUCTION Cogan's syndrome is a rare form of vasculitis mainly affecting young subjects of whatever gender, associating cochleovestibular and ophthalmological damage. Despite medical treatment, auditory prognosis is uncertain, with 50-60% of patients showing irreversible severe to profound hearing loss, thus being candidates for cochlear implantation. Following CARE guidelines, we report 10 cases of cochlear implantation in Cogan's syndrome, with assessment of speech reception threshold and maximum intelligibility after a minimum 1 year's experience with the implant. CASE SERIES Ten patients from 4 centers received cochlear implants (14 implants) for Cogan's syndrome between 2005 and 2020. After 1 year's experience, there was significant improvement in speech reception threshold (P=0.0002) and maximum intelligibility (P=0.0002). CONCLUSION-DISCUSSION Audiovestibular signs associated with ophthalmological manifestations should suggest Cogan's syndrome. Hearing impairment is usually irreversible. Cochlear implantation may be necessary and improves hearing performance.

Abstract
OBJECTIVES This study aimed to investigate predictive factors for revision surgery in otosclerosis. METHODS This was a retrospective, multicentre study in four tertiary centres. The primary objective was to investigate factors that were predictive of the need for revision stapes surgery. RESULTS The 'revision' group included 145 patients, and the 'control' group included 143 patients. This study identified statistically significant predictive factors for the need for revision surgery: younger age, active smoking status, dyslipidaemia and high blood pressure. There was no statistically significant difference between the two groups in terms of surgical technique or stapedotomy technique. CONCLUSION This study showed that patients who are candidates for primary stapes surgery with younger age, active smoking status, dyslipidaemia and high blood pressure are at higher risk of needing revision surgery. A holistic approach prior to stapes surgery with multidisciplinary assessment is recommended. These results are important for better patient counselling on expected outcomes and risks.

Abstract
Populations in countries such as Haiti demonstrate a high level of need for mental health care despite a lack of services and trained professionals. In addition to the dearth of biomedical services, local belief systems and explanatory models contribute to a majority of the population relying on traditional medicine as their first option for care. Using a mixed-methods approach, we aim to characterise mental illness at the first mental health clinic in the region - Sant Sante Mantal Mòn Pele (SSMMP) - by interviewing 96 patients with a demographic questionnaire as well as Anxiety, Depression, and Functionality Scales. Multivariate logistic and linear regression models were conducted examining the impact of demographic variables on whether patients believed their illness was caused by sent spirits or previously visited a Vodou priest for treatment, as well as Depression, Anxiety, and Functionality Scale scores. Factors associated with mental illness in this sample included sex, number of traumatic events, physical health status, and number of sessions attended at SSMMP. Factors which impacted traditional beliefs or practices related to mental illness included sex, age, and income.

Abstract
Very little is known in Haiti and the Caribbean regarding child and lifetime sexual victimization. Using a nationally representative sample of adolescents and young adults aged 15-24, this study aimed to document the prevalence, risk factors and mental health correlates of lifetime and child sexual violence in Haiti. A national cross-sectional surrvey was conducted in Haiti, using a multistage sampling frame, stratified by geographical department, urban or rural setting, gender, and age groups (15-19 and 20-24 years). The final sample included 3586 household participants (47.6% female). A weighted sample of 3945 individuals was obtained and used in the following analyses. Overall rate of lifetime and child sexual violence was, respectively, 27.44% (95% CI 25.94-28.94) and 11.27% (95% CI 10.18-12.35). Lifetime sexual violence rate was significantly higher among female participants (29.02%; 95% CI 27.5-30.55) compared to male (25.73%, 95% CI 24.26-27.2), χ2 = 4.63, p < .05, but there was no significant gender difference for child sexual victimization. Experiences of family physical violence, emotional abuse by mother and father, divorce of parents, and other physical violence were strongly associated with higher odds of sexual victimization. Participants who reported having experienced sexual violence are more at risk to meet criteria of PTSD (OR = 1.96, 95% CI 1.66-2.32; p < .0001), depression (OR = 1.73, 95% CI 1.47-2.02; p < .0001), psychological distress (OR =1.72, 95% CI 1.47-2.02; p < .0001), and substance abuse (OR = 1.33, 95% CI 1.13-1.57; p < .0001). Findings demonstrate that sexual violence is a public health emergency in Haiti. They provide evidence for the development of prevention and intervention programs.

Abstract
OBJECTIVE The role of personality traits in self-asphyxial behaviors remains largely unexplored. The aim of this study was to explore temperament and character profiles of youth reporting participation in the choking game using Cloninger's biopsychosocial model of personality. METHODS Data were collected among French middle-school students (N=1771) aged 9-16 years (mean age=13.0, SD=1.3) and randomly selected from 13 public establishments located in different regions of France. Logistic regression models were run to identify Cloninger's temperamental and character dimensions associated with engagement in the choking game. RESULTS Descriptive analysis revealed that participants showed high scores of novelty-seeking (Cohen's d=0.293, p<0.001) and low levels of cooperativeness (Cohen's d=0.182, p<0.01), persistence (Cohen's d=0.182, p<0.05), and reward dependence (Cohen's d=0.241, p<0.01). However, multivariate modeling indicated that only the novelty-seeking dimension tended to slightly differentiate participants from non-participants within the global sample (OR=1.03, 95% CI: 1-1.06). When we compared girls and boys, we found a slight trend in association only in boys (OR=1.04, 95% CI: 1-1.08). CONCLUSIONS Our study, which contributes to the growing literature on the psychological correlates of choking activities and is the first to investigate the potential predictive role of personality traits in this risky behavior, suggests to some extent that (a) the choking game could possibly be influenced by some temperamental characteristics, and that (b) it might not have the same function according to the gender considered.

Abstract
Many long-term childhood cancer survivors suffer from treatment-related late effects, which may occur in any organ and include a wide spectrum of conditions. Long-term follow-up (LTFU) is recommended to facilitate early diagnosis and to ensure better health outcomes. Due to the heterogeneity of these sequelae, different specialists work together in the diagnosis and treatment of these conditions. Experts from both pediatric and internal medicine are involved in age-appropriate care by providing a transition process. Hence, LTFU of childhood cancer survivors is a prototypic example of multidisciplinary care for patients with complex needs treated in a specialized setting. International collaborations of healthcare professionals and scientists involved in LTFU of childhood cancer survivors, such as the International Guideline Harmonization Group, compile surveillance recommendations that can be clinically adopted all over the world. These global networks of clinicians and researchers make a joint effort to address gaps in knowledge, increase visibility and awareness of cancer survivorship and provide an excellent example of how progress in clinical care and scientific research may be achieved by international and multidisciplinary collaboration.

Abstract
Abstract
Study question
What is the impact of the type of myeloablative conditioning (MAC) regimen applied for hematopoietic stem cell transplantation (HSCT) on uterine volume of childhood leukemia survivors?
Summary answer
Uterine volume is significantly decreased after HSCT. Not only Total Body Irradiation (TBI), but also high-dose chemotherapy-based regimens containing alkylating agents induce uterine damage.
What is known already
Premature ovarian failure after HSCT is well known, as well as the uterine damage induced by TBI on uterine volume. A few studies have reported smaller uterus after HSCT in women treated with chemotherapy only. In these studies, uterus volume was assessed by a transabdominal and/or transvaginal ultrasonography, and primary diagnosis, age at treatment and chemotherapy regimen were heterogeneous. These preliminary results suggested that alkylating agents could induce uterine damage, as well as they induce fibrosis and vascular damage in ovarian stroma. The impact of chemotherapy on myometrium and uterus is still few investigated.
Study design, size, duration
A prospective multicentric national study was conducted between 2017, November and 2021, June in 16 University Teaching Hospitals that are following more than 4 500 childhood acute leukemia survivors enrolled in the L.E.A cohort. We included 88 adult women treated for a childhood acute leukemia with HSCT and who agreed a pelvic MRI assessment. Every case was matched 1:1 to control women who underwent MRI for benign ovarian cysts or benign pelvic pathology.
Participants/materials, setting, methods
Pelvic MRI scans were performed with a 1.5-T or 3T magnetic resonance scanner, including diffusion-weighted imaging sequences. Scans were centralized for a double-blinded lecture by two radiologists. The main outcome was the uterine volume. The secondary outcomes were uterine body-to-cervix ratio and apparent diffusion coefficient (ADC). Univariate and multivariate analyses have investigated the association of clinical and imaging variables with conditioning regimen and age at HSCT.
Main results and the role of chance
The mean age in HSCT group was 26.5 + 6.3 years. Mean age at HSCT was 9.1 + 0.3 years with a mean follow-up of 16.4 + 0.5 years. Among the 88 women included in HSCT group, two groups of conditioning regimens have been compared to the control group: a chemotherapy-only MAC regimen group with high dose of alkylating agents (n = 34) and one TBI-based regimen group (n = 52). Two MRI scans were not available. Among HSCT group, 75 women were considered as “normally impregnated” by estrogens, by hormone replacement therapy (HRT) for premature ovarian insufficiency (POI) or thanks to a residual ovarian function. Uterine volume was significantly decreased both after chemotherapy-only MAC regimen and after TBI, with respectively 45.3 + 5.6 and 19.6 + 1.9 mL Vs 79.7 + 3.3 mL in control population (p < 0.01). In chemotherapy-only MAC regimen group, uterine volume was dramatically decreased in POI women without HRT compared to those having a hormonal impregnation (15.2 + 2.6 Vs 49.3 + 6 mL, p < 0.05). In contrast, after TBI, uterine volume was similar in all women, with no positive effect of HRT on uterine volume (respectively 16.3 + 2.6 Vs 20.1 + 2.2 mL).
Limitations, reasons for caution
The number of pregnancies obtained spontaneously or after oocyte donation in our study population was too low to evaluate the obstetrical impact of uterine damage caused by non-TBI regimens.
Wider implications of the findings
Our results provide strong evidence that a MAC regimen containing high dose of alkylating agents could induce uterine damage. In these sub-group of women, HRT increases the volume of the uterus compared to non-treated women. After TBI, uterine volume is dramatically decreased, with no benefit of HRT on it.

Immunomodulatory effect of different statin regimens on regulatory T-cells among patients with acute coronary syndrome: a systematic review and network meta-analysis of randomized clinical trials
Introduction
In patients with acute coronary syndrome (ACS), studies suggest that statin therapy, besides its role in reducing the progression of atherosclerosis through its pharmacological effect, plays a pivotal role in controlling the pathogenesis of ACS through the anti-inflammatory effects of suppressor regulatory T cells (Tregs).
Purpose
We conducted a network meta-analysis (NMA) to determine the effects of low-dose conventional statin therapy (CST) (20 mg/day or less) and high-dose intensive statin therapy (IST) (40 mg/day or more) on the frequency of Tregs and their associated cytokines (IFN-γ, IL-10, TGF-β), compared to placebo.
Methods
The PubMed, Cochrane Library, and EMBASE databases were searched for randomized clinical trials (RCTs) to identify relevant articles published until June 2021. We pooled data extracted from the included studies using the standardized mean difference (SMD). A random-effects model was used to conduct this NMA. Heterogeneity was evaluated using Cochran's Q- and the I2-test. GRADE(Grading of Recommendations, Assessment, Development and Evaluations) was used to assess the study's quality. Data analysis was conducted using R software.
Results
A total of 505 patients were enrolled in the 5 RCTs. The NMA indicated a significant increase in Treg frequency in the CST group compared with the control group (SMD 1.77; 95% CI: 0.77 – 2.76; P-value = 0.0005) and a larger increase in the Treg frequency associated with the IST group compared with the control group (SMD 2.12; 95% CI: 1.15 – 3.10; P-value < 0.0001). However, there was significant heterogeneity and inconsistency among the included studies (τ2 = 0.6096; τ = 0.7808; I2 = 91.2% [80.5%; 96.0%]). When compared to the placebo, both CST and IST increased levels of secreted IL-10 (SMD 2.69; 95% CI: 2.07 – 3.31; P-value < 0.0001 and (SMD 2.14; 95% CI: 1.76 – 2.52; P-value < 0.0001), respectively. In comparison to the control group, CST was associated with increased levels of TGF-β (SMD 3.83; 95% CI: 0.63 – 7.0; P-value = 0.0189). This association was not seen in the IST group. IFN-γ levels decreased significantly in both the IST and CST groups (SMD -1.52; 95% CI: -1.94 – -1.10; P-value < 0.0001) and (SMD -2.34; 95% CI: -2.73 – -1.95; P-value < 0.0001) respectively.
Conclusions
Our study suggests that both high and low dose statin groups showed increased Treg frequency compared to the placebo group. IST showed larger benefits. Statin therapy also increased IL-10 and TGF-β cytokine levels and decreased IFN-γ levels. Therefore, statins have the potential to be the main treatment to reduce the incidence of cardiovascular events and improve cardiac function in patients with ACS through immunomodulatory effect on Treg.

Abstract
BACKGROUND Studies examining both victimization and perpetration of dating violence among both women and men are virtually non-existent in Haiti. This study aimed to document the prevalence and factors associated with victimization and perpetration of dating violence (DV) among adolescents and young adults aged 15-24 years in Haiti. PARTICIPANTS AND SETTING A total of 3586 participants (47.6% women; mean age = 19.37; SD = 2.71) were sampled in the 10 geographical departments according to residence areas (urban/rural), age group (15-19/20-24 years old), and gender (men/women). METHOD Participants completed questionnaires assessing DV victimization and perpetration, witnessing interparental violence, parental violence, violence acceptance, social desirability, and self-esteem. RESULTS Overall, 1538 participants (56% women) were in a romantic relationship in the past year. Results showed that men were more likely to experience both psychological (49.4% of women and 57% of men, X2 = 8.17, p = .004), and physical violence (11.1% of women and 18.8% of men, X2 = 8.13, p = .004). There were marginally significant differences for sexual violence between gender for adolescents aged 15 to 19 (26.5% of girls and 20.5% of boys, X2 = 3.25, p = .07), and not for young adults (21.8% of women and 24.0% of men, X2 = 0.49, p = .48). No significant difference was observed for any forms of DV perpetration. DV perpetration was positively associated with victimization (b = 0.5, p = .002), however victimization was not associated with perpetration. Results also showed different associations between violence perpetration and victimization, gender, social desirability, acceptance of violence, parental violence, and witnessing interparental violence. CONCLUSIONS This study highlights avenues for prevention and intervention that must begin at an early age, engage teachers, train peer-educators, promote healthy, non-violent and egalitarian romantic relationships.

Abstract
AIM The aim of this study was to evaluate the impact of cochlear reimplantation (CR) on hearing performance in children and adults with severe to profound hearing loss. MATERIAL AND METHODS Retrospective observational study. OBJECTIVES The main objective of this study was to determine whether there was a difference in hearing performance before and after CR. Secondary objectives were to analyze reasons for CR; to assess correlations between auditory performance and complete electrode reinsertion during CR, age, gender, explantation-to-CR interval, and interval between first implantation and CR; and to assess difference in APCEI score and the French evaluation protocol for implanted patients before and after CR. RESULTS Comparison of speech perception scores before and after explantation-reimplantation showed no significant difference (P>0.005) at 1 year or at 2 years after CR. In 80% of cases, reimplantation was due to hard implant failure. In other cases, it was undertaken for soft failure (diminished performance but no abnormalities on integrity testing) (8%), medical reasons (6%), or undetermined reasons (6%). There was no significant correlation between auditory performance at 1 or 2 years and complete or incomplete reinsertion of electrodes, age, gender, explantation-to-CR interval, or interval between first implantation and CR (P>0.005). For the adult subgroup, the French evaluation protocol scores did not differ after reimplantation (P=0.62). Likewise, for the child sub-group, APCEI and CAP results did not deteriorate after reimplantation. CONCLUSION Reimplantation had no negative impact on hearing and speech perception, but provided performance equivalent to or better than after initial implantation.

Sutureless venous microanastomosis using thermosensitive poloxamer and cyanoacrylate: experimental study on a rat model. J Plast Reconstr Aesthet Surg 2021; 75:433-438. [PMID: 34247962 DOI: 10.1016/j.bjps.2021.05.072] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 05/08/2021] [Accepted: 05/28/2021] [Indexed: 02/01/2023]
Abstract
INTRODUCTION Sutureless microvascular anastomoses could simplify the microvascular field, shortening operative time and improving the final outcome. The use of thermosensitive poloxamers (TP407) together with the application of cyanoacrylate as an alternative method for conventional sutures was well-documented for arteries, but not for veins. The purpose of our study was to prove the feasibility of this technique for venous anastomoses and compare it with the traditional hand-sewn technique on a rat model. MATERIALS AND METHODS Twenty male Sprague-Dawley rats that weighed between 265 and 310 g were used. In the sutureless group (SG), 20 left external jugular veins (LEJV) end-to-end anastomoses were performed using a T704 and cyanoacrylate glue. They were compared to 20 right external jugular veins (REJV) anastomoses sutured with conventional 10-0 stitches (control group - CG). Diameters of veins, anastomosis time, and patency rate at 15 days were reported. Foreign body reaction was assessed histologically. RESULTS The mean diameter of the LEJV was 0.94 ± 0.1 mm and 0.95 ± 0.09 mm for the REJV. The mean anastomosis time was 11.9 ± 1.37 min for the SG and 27.75 ± 3.31 min for the CG. In the latter group, the immediate patency rate was 95% and 90% at 15 days. For the SG group, 90% of the anastomoses were patent immediately and 85% at 15 days. CONCLUSION TP407 and cyanoacrylate could offer a fast and reliable technique for sutureless venous anastomoses. Before human application, effectiveness of this method remains to be confirmed in larger animals in a long-term follow-up.

Abstract
When people living in poverty are asked to describe their living conditions, mental health issues quickly come to mind (grief, sadness, anger, fear, bitterness, frustration, discontent, anxiety, and emotional damage consisting of low mood and depression, fatigue, hypersensitivity, sleep difficulties and physical pain). Although the association between poverty and mental health have been widely demonstrated in the literature, care must be taken to avoid the psychiatrization of poverty. However, how can healthcare be provided to people living in poverty when basic needs are not met? This article explores the global challenge of providing mental health services in impoverished populations, using the example of the poorest country in America: Haiti. It examines the availability of services offered through the Mental Health Centre at Morne Pelé, and the necessity for innovative and comprehensive approaches to provide culturally appropriate care that meets the real needs of populations. It highlights effective measures that policy makers should implement to develop an efficient mental healthcare system based on the lessons of the Mental Health Centre at Morne Pelé.

CD11c + dendritic cells mediate antigen-specific suppression in extracorporeal photopheresis. Clin Exp Immunol 2020; 203:329-339.

Abstract
Extracorporeal photopheresis (ECP) represents one of the most widespread and effective cell therapies for graft‐versus‐host disease and other T cell‐mediated disorders. However, the key factors affecting the therapeutic efficacy of ECP remain unclear. We hypothesized that therapeutic effects are mediated by ECP‐treated antigen‐presenting dendritic cells (DC). To test this hypothesis, we used the experimental model of contact hypersensitivity (CHS). The ECP’s therapeutic activity improved when the total cell dose of the ECP‐treated cells was increased. We used different haptens during sensitization to demonstrate that the anti‐inflammatory activity of ECP is antigen‐specific. This confirmed the hypothesis that professional antigen‐presenting cells are involved in the mode of action. Also, the ECP’s therapeutic activity was abrogated by the depletion of CD11c+ DC, which represents fewer than 1% of all the ECP‐exposed cells. Finally, we confirm the critical importance of CD11c+ DC for ECP activity by showing that only a few purified CD11c+ DC are sufficient to mediate its therapeutic effect. The finding that ECP‐treated, physiological antigen‐presenting DC alone mediate antigen‐specific modulation of a pathological immune response may result in better‐targeted interventions when treating patients.

Clinical, functional and genetic characterization of 16 patients suffering from chronic granulomatous disease variants - identification of 11 novel mutations in CYBB. Clin Exp Immunol 2020; 203:247-266.

Abstract
Chronic granulomatous disease (CGD) is a rare inherited disorder in which phagocytes lack nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity. The most common form is the X-linked CGD (X91-CGD), caused by mutations in the CYBB gene. Clinical, functional and genetic characterizations of 16 CGD cases of male patients and their relatives were performed. We classified them as suffering from different variants of CGD (X910 , X91- or X91+ ), according to NADPH oxidase 2 (NOX2) expression and NADPH oxidase activity in neutrophils. Eleven mutations were novel (nine X910 -CGD and two X91- -CGD). One X910 -CGD was due to a new and extremely rare double missense mutation Thr208Arg-Thr503Ile. We investigated the pathological impact of each single mutation using stable transfection of each mutated cDNA in the NOX2 knock-out PLB-985 cell line. Both mutations leading to X91- -CGD were also novel; one deletion, c.-67delT, was localized in the promoter region of CYBB; the second c.253-1879A>G mutation activates a splicing donor site, which unveils a cryptic acceptor site leading to the inclusion of a 124-nucleotide pseudo-exon between exons 3 and 4 and responsible for the partial loss of NOX2 expression. Both X91- -CGD mutations were characterized by a low cytochrome b558 expression and a faint NADPH oxidase activity. The functional impact of new missense mutations is discussed in the context of a new three-dimensional model of the dehydrogenase domain of NOX2. Our study demonstrates that low NADPH oxidase activity found in both X91- -CGD patients correlates with mild clinical forms of CGD, whereas X910 -CGD and X91+ -CGD cases remain the most clinically severe forms.

Abstract
We report on the observation of surface gravity-wave turbulence at scales larger than the forcing ones in a large basin. In addition to the downscale transfer usually reported in gravity-wave turbulence, an upscale transfer is observed, interpreted as the inverse cascade of weak turbulence theory. A steady state is achieved when the inverse cascade reaches a scale in between the forcing wavelength and the basin size, but far from the latter. This inverse cascade saturation, which depends on the wave steepness, is probably due to the emergence of nonlinear dissipative structures such as sharp-crested waves.

Abstract
The identification of the mechanisms by which marine dissolved organic matter (DOM) is produced and regenerated is critical to develop robust prediction of ocean carbon cycling. Polysaccharides represent one of the main constituents of marine DOM and their degradation is mainly attributed to polysaccharidases derived from bacteria. Here, we report that marine viruses can depolymerize the exopolysaccharides (EPS) excreted by their hosts using five bacteriophages that infect the notable EPS producer, Cobetia marina DSMZ 4741. Degradation monitorings as assessed by gel electrophoresis and size exclusion chromatography showed that four out of five phages carry structural enzymes that depolymerize purified solution of Cobetia marina EPS. The depolymerization patterns suggest that these putative polysaccharidases are constitutive, endo-acting and functionally diverse. Viral adsorption kinetics indicate that the presence of these enzymes provides a significant advantage for phages to adsorb onto their hosts upon intense EPS production conditions. The experimental demonstration that marine phages can display polysaccharidases active on bacterial EPS lead us to question whether viruses could also contribute to the degradation of marine DOM and modify its bioavailability. Considering the prominence of phages in the ocean, such studies may unveil an important microbial process that affects the marine carbon cycle.

Abstract
Autism Spectrum Disorders (ASD) are associated with higher levels of anxiety for parents [1]. Provide medical information about autism etiology is the first step to help parents to understand the child disorder and to cope with it. The medical current community accepts that autism is a neurodevelopmental disorder in which genes play a role but that environmental factors likely contribute as well [2]. This conception can meet parent's beliefs constructed on their cultural values and personal experiences. In line with causal attribution theory [3], it is important to consider to parental beliefs because it can impact the treatment choices and the child developmental trajectory [4]. The Main purpose is to evaluate the consistency between parental knowledge and beliefs about ASD etiology. The second purpose is to explore the impact of consistency on parents’ anxiety. We interviewed through open-ended questions 89 parents of ASD children aged between 3 to 10 years about their knowledge and their beliefs about ASD etiology. A content analysis was performed using the Nvivo10 software. Anxiety is evaluated with the subscale of the Hospital Anxiety and Depression Scale (HADS). In agreement with previous work four categories of causes have been identified: biological (BIO), psychological (PSY), multifactorial etiology (BIO + PSY), others (OT). A percentage of 55.1% of parents is consistent between their knowledge and beliefs about ASD etiology while 43.8% are inconsistent. Parent anxiety is significantly higher (T (71.91) = 2.34; P < 0.05) when knowledge and beliefs are inconsistent than when they are consistent. This study demonstrates the deleterious impact of inconsistency between knowledge and beliefs about ASD etiology, on parental anxiety. In order to provide relevant support for parents, information delivered after diagnosis must consider pre-existing parental beliefs. A systematic assessment of parental beliefs would adjust the information provided after the diagnosis.

Abstract
OBJECTIVES Peripheral neck nerve tumors are rare and mostly benign neoplasms. The exceptional malignant forms are very aggressive, and diagnosis is difficult. The objective of this study was to evaluate diagnostic and therapeutic management and identify possible predictive factors. MATERIAL AND METHODS A retrospective study was conducted of 73 patients treated for peripheral neck nerve tumor between 1995 and 2015. RESULTS Mean age was 44years. The main presenting symptom was a cervical mass, isolated or associated with signs related to the affected nerve structure. Diagnosis was suspected by slow progression of a firm mass, featuring T1 hyposignal and T2 hypersignal on magnetic resonance imaging. Surgery was performed in 99% of cases, completed by adjuvant chemotherapy in case of malignant neuroblastic tumor. Type 1 neurofibromatosis and sudden increase in mass with or without associated pain suggested malignant transformation. Age below 10years suggested neuroblastic tumor. CONCLUSION Neck nerve tumors are very often benign with low degenerative potential. Surgery is the treatment of choice after risk/benefit analysis. However, there is no clearly defined consensus regarding the timing of surgery for these lesions.

Abstract
The paradox of methane oversaturation in oxygenated surface water has been described in many pelagic systems and still raises the question of the source. Temora sp. and Acartia sp. commonly dominate the surface and subsurface waters of the central Baltic Sea. It is hypothesised that their gut microbiome at least partly contributes to the methane anomaly in this ecosystem. However, the potential pathway for this methane production remains unclear. Using a microcapillary technique, we successfully overcame the challenge of sampling the gut microbiome of copepods <1 mm. 16S rRNA gene amplicon sequencing revealed differences among the dominant bacterial communities associated with Temora sp. (Actinobacteria, Betaproteobacteria and Flavobacteriia) and Acartia sp. (Actinobacteria, Alphaproteobacteria and Betaproteobacteria) and the surrounding water (Proteobacteria, Cyanobacteria and Verrucomicrobia), but also intraspecific variability. In both copepods, gut-specific prokaryotic taxa and indicative species for methane production pathways (methanogenesis, dimethylsulfoniopropionate or methylphosphonate) were present. The relative abundance of archaea and methanogens was investigated using droplet digital polymerase chain reaction and showed a high variability among copepod individuals, underlining intra- and interspecific differences in copepod-associated prokaryotic communities. Overall, this work highlights that the guts of Temora sp. and Acartia sp. have the potential for methane production but are probably no hotspot.

Abstract
This article illustrates the application of multiple scales analysis to two archetypal quasi-linear systems; i.e. to systems involving fast dynamical modes, called fluctuations, that are not directly influenced by fluctuation-fluctuation nonlinearities but nevertheless are strongly coupled to a slow variable whose evolution may be fully nonlinear. In the first case, fast waves drive a slow, spatially inhomogeneous evolution of their celerity field. Multiple scales analysis confirms that, although the energy E, the angular frequency ω and the modal structure of the waves evolve, the wave action E/ω is conserved in the absence of forcing and dissipation. In the second system, the fast modes undergo an instability that is saturated through a feedback on the slow variable. A new multi-scale analysis is developed to treat this case. The key technical point, confirmed by the analysis, is that the fluctuation energy and mode structure evolve slowly to ensure that the slow field remains in a state of near marginal stability. These two model systems appear to be generic, being representative of many if not all quasi-linear systems. In each case, numerical simulations of both the full and reduced dynamical systems are performed to highlight the accuracy and efficiency of the multiple scales approach. Python codes are provided as electronic supplementary material.

Abstract
BACKGROUND The impact of Staphylococcus aureus on onset of nasal polyposis has been the focus of numerous studies, but there have been few studies of other germs found in the ethmoid of operated patients or of their impact on post-operative results. MATERIAL AND METHODS All patients undergoing endoscopic radical ethmoidectomy for nasal polyposis in the teaching hospital of Nantes (France) between 2006 and 2016 had intraoperative ethmoid cavity bacterial sampling. Phenotypic characteristics, pre- and post-operative symptoms and endoscopic findings were analyzed. Mann-Whitney tests and Kruskal-Wallis correlation analysis were used to assess clinical/bacteriological correlations. OBJECTIVES The main objective was to describe bacterial colonization of patients undergoing surgery for nasal polyposis, and to assess correlations with phenotypic features, functional results and postoperative clinical course. RESULTS One hundred and seven patients were included. A total of 26% were not infected, 55% mono-infected and 19% multi-infected. In 27.3%, staphylococci were isolated; in 30.5%, isolates were gram-negative bacilli. There were no significant correlations between presence or type of pathogen and symptom profile. CONCLUSION This study confirmed the high rate of pathogenic bacteria in nasal cavities in case of polyposis, with high frequencies of S. aureus but also of gram-negative bacilli, raising the question of their involvement in the inflammatory reactions underlying the nasal polyposis.

Abstract
PURPOSE Grandparents can be profoundly emotionally affected when a grandchild is diagnosed with cancer. They also often provide invaluable support for the family (e.g., caring for the sick child and/or siblings). Multigenerational family functioning may therefore change. Limited research has assessed grandparents' perspectives after their grandchild is diagnosed with cancer. In this study, we aimed to (1) assess differences in perceived family functioning among grandparents of a child with cancer and grandparents of healthy children and (2) assess the cancer-specific and demographic factors related to perceived family functioning in grandparents of a grandchild with cancer. PROCEDURE Grandparents of a child with cancer (n = 89) and grandparents of healthy children (n = 133) completed the general functioning, communication, and problem-solving scales of the Family Assessment Device. We used multilevel models with a random intercept to detect (1) between-group differences and (2) identify factors related to perceived family functioning among grandparents with a grandchild with cancer. RESULTS Grandparents with a grandchild with cancer reported poorer family functioning than grandparents with healthy grandchildren. Among the grandparents with a grandchild with cancer, impairments in family functioning were correlated with fewer years since diagnosis, providing care to their sick grandchild and/or siblings and living far away from the sick grandchild. CONCLUSIONS The detrimental impact of childhood cancer likely extends beyond the immediate family members. Including grandparents in interventions-beginning at diagnosis-to reduce distress and increase cohesion for families of a child with cancer is warranted, particularly for grandparents who provide care to their sick grandchild or siblings.

Genetic polymorphisms of Th2 interleukins, history of asthma or eczema and childhood acute lymphoid leukaemia: Findings from the ESCALE study (SFCE). Cancer Epidemiol 2018; 55:96-103.

Abstract
BACKGROUND Previous studies on the putative role of allergy in the aetiology of childhood leukaemia have reported contradictory results. The present study aimed to analyse the relation between a medical history of asthma or eczema and childhood acute lymphoid leukaemia (ALL) in light of potential candidate gene-environment interactions. METHODS Analyses were based on a subset of 434 cases of ALL and 442 controls successfully genotyped and of European ancestry children enrolled in a French population-based case-control study conducted in 2003-2004. Information about medical history was obtained during a standardized interview with the mothers. Candidate polymorphisms in genes of the Th2 cytokines IL4, IL10, IL13 and IL4-receptor, were genotyped or imputed. RESULTS None of the variant alleles were directly associated with childhood acute lymphoid leukaemia. A medical history of asthma or eczema was reported more often in the control group (OR = 0.7 [0.5-1.0]). This association was mostly seen in the group of children not carrying the IL13-rs20541 variant allele (Interaction Odds Ratio IOR 1.9, p-interaction = 0.07) and in those carrying the IL10 triple variant haplotype (IOR 0.5, p-interaction = 0.04). No interaction was observed with the candidate polymorphisms in IL4 and IL4R. CONCLUSION This study provides a new insight into the relationship between allergic symptoms and childhood acute lymphoid leukaemia, by suggesting this inverse association could be limited to children carrying certain genetic polymorphisms. If confirmed, these results could help better understand the biological mechanisms involved in the development of childhood acute lymphoid leukaemia.

Abstract
The increase in the number of patients who undergo massive weight loss surgery has led to an increasing number of patients who complain of circumferential abdominal skin and soft tissue excess. Currently, the only surgical option to treat soft tissue excess is vertical median abdominal lipectomy (fleur-de-lys technique). However, many patients are reluctant to undergo this surgery because of the position of the scar. We presented a new surgical approach to manage circumferential excess - dorsal median lipectomy (arrow technique) - in which the dorsal scar is well-tolerated by patients.

Abstract
BACKGROUND The contribution of mental health to the risk of smoking is increasingly acknowledged but still insufficiently studied during the key period of student life. In particular, the simultaneous action of stress and Attention Deficit Hyperactivity Disorder (ADHD) symptoms on the risk of smoking remains poorly understood. AIMS To assess the effects of stress and ADHD symptoms on tobacco smoking. METHOD Multivariate modeling was conducted on the French i-Share study (n=8110, median age 20.3 years, 74.8% females, 32.9% regular/occasional smokers) to evaluate the associations between stress, ADHD symptoms and tobacco smoking, adjusting for potential family/socio-demographic confounders. RESULTS Students with high levels of stress were more likely to smoke>10 cigarettes/day (adjusted odds ratio (aOR): 1.48, 95% CI: 1.12-1.96) than those with low levels of stress. Students with high levels of ADHD symptoms were more likely to smoke>10 cigarettes/day (aOR: 2.08, 95% CI: 1.58-2.75) than those with low levels of ADHD symptoms. CONCLUSIONS Stress and ADHD contribute independently to the risk of smoking. Interventions targeting each condition are likely to reduce the burden of tobacco use in students.

Clinical impact of NK-cell reconstitution after reduced intensity conditioned unrelated cord blood transplantation in patients with acute myeloid leukemia: analysis of a prospective phase II multicenter trial on behalf of the Société Française de Greffe de Moelle Osseuse et Thérapie Cellulaire and Eurocord.

Abstract
Unrelated cord blood transplantation (UCBT) after a reduced intensity conditioning regimen (RIC) has extended the use of UCB in elderly patients and those with co-morbidities without an HLA-identical donor, although post-transplant relapse remains a concern in high-risk acute myeloid leukemia (AML) patients. HLA incompatibilities between donor and recipient might enhance the alloreactivity of natural killer (NK) cells after allogeneic hematopoietic stem-cell transplantation (HSCT). We studied the reconstitution of NK cells and KIR-L mismatch in 54 patients who underwent a RIC-UCBT for AML in CR in a prospective phase II clinical trial. After RIC-UCBT, NK cells displayed phenotypic features of both activation and immaturity. Restoration of their polyfunctional capacities depended on the timing of their acquisition of phenotypic markers of maturity. The incidence of treatment-related mortality (TRM) was correlated with low CD16 expression (P=0.043) and high HLA-DR expression (P=0.0008), whereas overall survival was associated with increased frequency of NK-cell degranulation (P=0.001). These features reflect a general impairment of the NK licensing process in HLA-mismatched HSCT and may aid the development of future strategies for selecting optimal UCB units and enhancing immune recovery.

Abstract
The Cassini spacecraft orbiting Saturn carries the composite infrared spectrometer (CIRS) designed to study thermal emission from Saturn and its rings and moons. CIRS, a Fourier transform spectrometer, is an indispensable part of the payload providing unique measurements and important synergies with the other instruments. It takes full advantage of Cassini's 13-year-long mission and surpasses the capabilities of previous spectrometers on Voyager 1 and 2. The instrument, consisting of two interferometers sharing a telescope and a scan mechanism, covers over a factor of 100 in wavelength in the mid and far infrared. It is used to study temperature, composition, structure, and dynamics of the atmospheres of Jupiter, Saturn, and Titan, the rings of Saturn, and surfaces of the icy moons. CIRS has returned a large volume of scientific results, the culmination of over 30 years of instrument development, operation, data calibration, and analysis. As Cassini and CIRS reach the end of their mission in 2017, we expect that archived spectra will be used by scientists for many years to come.

Cytogenetics and outcome of allogeneic transplantation in first remission of acute myeloid leukemia: the French pediatric experience. Bone Marrow Transplant 2016; 52:516-521. [PMID: 27941778 DOI: 10.1038/bmt.2016.293] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2016] [Revised: 09/14/2016] [Accepted: 09/20/2016] [Indexed: 01/04/2023]
Abstract
We analyzed the impact of cytogenetics on 193 children enrolled in two successive French trials (LAME89/91 and ELAM02), who received hematopoietic stem cell transplantation during CR1. Detailed karyotype was available for 66/74 (89%) in LAME89/91 and 118/119 (99%) in ELAM02. Several karyotype and transplant characteristics differed according to therapeutic protocol: unfavorable karyotypes were more frequent in ELAM02 (36% vs 18%), pretransplant chemotherapy included high-dose cytarabine in ELAM02 and not in LAME89/91, IV replaced oral busulfan in the conditioning regimen, methotrexate was removed from post-transplant immunosuppression, and matched unrelated donor and cord blood transplantation were introduced. Five-year overall survival (OS) was 78.2% in LAME89 and 81.4% in ELAM02. OS was significantly lower for the unfavorable cytogenetic risk group in LAME89/91 when compared with intermediate and favorable groups (50% vs 90.6 and 86.4%, P=0.001). This difference was no longer apparent in ELAM02 (80.9% vs 71.3% and 5/5, respectively). Survival improvement for children with unfavorable karyotype was statistically significant (P=0.026) and was due to decrease in relapse risk. Five-year transplantation-related mortality was 6.75% in LAME89/91. In ELAM02, it was 3.2% for patients with a sibling donor and 10.9% with an unrelated donor or cord blood. We conclude that the outcome of children with unfavorable karyotype transplanted in CR1 has improved.
