Abstract
INTRODUCTION To describe a novel surgical approach in the management of subluxated cataracts. METHODS A 70-year-old Caucasian male with a subluxated cataract in the left eye was referred to our clinic at the Azienda Ospedaliero-Universitaria di Bologna- Ophthalmology Unit. The ophthalmic examination revealed a best-corrected visual acuity (BCVA) of 20/200 in the left eye with monocular diplopia and a severely subluxated NO6/NC6 cataract and the fundus examination did not reveal any vitreoretinal abnormalities. The right eye had 20/20 BCVA and was pseudophakic. After a 300° conjunctival peritomy, a single 25-gauge valved trocar 4 mm was inserted from the limbus in the inferotemporal quadrant, where the cataract was mainly dislocated and a corneal paracentesis to reduce the anterior chamber intraocular pressure was performed. Subsequently cohesive viscoelastic was progressively injected in the retrolental space through the trocar, to recenter and elevate the subluxated cataract. Thereafter, a complete centered capsulorhexis was performed, four capsular hooks were inserted to stabilize the bag, and complete phacoemulsification was performed with intact posterior capsular support. In the end, given the lack of capsular support elements such as the Cionni ring or Ahmed segment, a sutureless scleral fixated intraocular lens was implanted. RESULTS One week after surgery, the BCVA was 20/25, and the final BCVA at 6 months was 20/20, without any complications. CONCLUSIONS Retrolental cohesive ophthalmic viscoelastic injection could represent a novel effective surgical approach in recentering and elevating subluxated cataracts, facilitating the capsulorhexis, and reducing the risk of a pars plana approach.

Abstract
BACKGROUND To report a case of sutureless scleral-fixated hydrophilic intraocular lens (FIL SSF IOL, Soleko, Italy) opacification following pars plana vitrectomy surgery using sulfur hexafluoride (SF6) for traumatic lens luxation associated with retinal detachment. CASE PRESENTATION A 77-year-old woman was referred to our emergency department after blunt trauma in her right eye. At the ophthalmic evaluation, visual acuity was hand movement, biomicroscopy showed pseudoexfoliation syndrome and a traumatic lens luxation in the vitreous chamber. The patient underwent pars plana vitrectomy, subluxated cataract explantation, and FIL SSF IOL implant. During surgery, an inferior retinal detachment was encountered, requiring 20% SF6 gas tamponade. No adverse events were encountered. One month postoperatively, visual acuity (BCVA) improved to 0,3 logMAR. At the 3-month follow-up, the patient presented with BCVA of 0,5 logMAR, and biomicroscopy showed a minimal IOL opacification. Six months postoperatively, BCVA decreased to 1.0 logMAR, and diffuse, IOL opacification was noted at slit lamp examination. The patient refused any other surgical intervention for IOL exchange. CONCLUSIONS Although hydrophilic IOL opacification gas related is known, to the best of our knowledge, this is the first case reported in the literature of FIL SSF IOL opacification after pars plana vitrectomy with gas tamponade for retinal detachment.

Abstract
Objectifs Les modifications organisationnelles liées à la crise sanitaire COVID-19 (cours en distanciel et stage en service d’unités COVID pour certains externes) ont pu favoriser la détresse psychologique des étudiants inscrits en médecine habituellement exposés à une charge de travail intense. L’objectif de cette étude était d’évaluer la prévalence de la détresse psychologique chez les étudiants en médecine pendant la crise sanitaire du COVID-19, et d’identifier les facteurs associés à la détresse psychologique. Méthodes Une étude observationnelle transversale a été proposée à 1814 étudiants en médecine (de la première à la sixième année) dans un centre hospitalier universitaire français du 10 mars au 25 mars 2021. Un avis favorable du comité d’éthique a été obtenu (IRBN272021/CHUSTE). Des informations sociodémographiques, professionnelles et médicales (détresse psychologique mesurée sur l’échelle française GHQ12) ont été recueillies par le biais d’un questionnaire anonyme auto-administré en ligne. Les variables associées à la détresse psychologique ont été étudiées en utilisant une analyse univariée (test du Chi2 et Fisher). Les variables avec une valeur p < 0,2 ont été inclues dans un modèle de régression de Poisson modifiée et les variables avec une valeur de p < 0,05 ont été conservées dans le modèle. Résultats Au total, 832 étudiants en médecine ont répondu (46 %) et 699 ont rempli le questionnaire en entier (39 %) : 625 (75 %) ont montré des signes de détresse psychologique et 109 (15 %) ont rapporté des idées suicidaires. Le sexe féminin, un traumatisme psychologique lors de la crise sanitaire COVID-19, une modification de la consommation d’alcool et des difficultés liées à l’enseignement en distanciel étaient positivement associés à la détresse psychologique, alors qu’un sentiment d’entraide et de coopération dans le cadre des études, la reconnaissance du travail effectué étaient négativement associés à la détresse psychologique. Un stage dans une unité COVID n’apparaît pas significativement associé à la détresse psychologique. Conclusions Des soins de santé mentale intégrant la prévention du suicide devraient être proposés aux étudiants à risque dans ce contexte de crise sanitaire COVID-19. Connaître les facteurs éducatifs et médicaux associés à la détresse psychologique permet d’identifier des axes de prévention.

Abstract
Functional hypothalamic amenorrhea (FHA) is a temporary infertility characterized by the suppression of the hypothalamic-pituitary-gonadal (HPG) axis, induced by the inhibition of the hypothalamic pulsatile secretion of the gonadotropin-releasing hormone (GnRH), in the presence of stressors, including eating disorders, excessive exercise, and psychological distress. Although the stressful factors that may lead to FHA are well-established, little is known about the inter-individual variability in response to stress and the consequent inhibition of the HPG axis. Not all women, indeed, manifest FHA in presence of stressful conditions. Recent studies highlighted a genetic contribution to FHA. Rare or polymorphic variants in genes that control the development and/or function of GnRH neurons may contribute, indeed, to the adaptability of the reproductive axis to stress factors. Also epigenetic changes have been associated with different pathways involved in the HPG axis and therefore, take part in FHA and confer a personal predisposition to anovulation consequent to a stressful event, or represent biological markers of response to stress. This review summarizes recent advances in the identification of the contribution of (epi)genetics to FHA and to long-term complications of functional amenorrhea, and reports insights into the involvement of additional genetic loci in FHA development on the bases of the clinical and molecular overlap with other gynecological and/or psychological conditions. Finally, we describe the promising application of induced pluripotent stem cells (iPSCs) as a new approach to investigate the molecular pathways involved in FHA.

Abstract
Myotonic dystrophy type 2 (DM2) is a multisystemic disorder caused by a (CCTG)n in intron 1 of the CNBP gene. The CCTG repeat tract is part of a complex (TG)v(TCTG)w(CCTG)x(NCTG)y(CCTG)z motif generally interrupted in CNBP healthy range alleles. Here we report our 14-year experience of DM2 postnatal genetic testing in a total of 570 individuals. The DM2 locus has been analyzed by a combination of SR-PCR, TP-PCR, LR-PCR, and Sanger sequencing of CNBP alleles. DM2 molecular diagnosis has been confirmed in 187/570 samples analyzed (32.8%) and is mainly associated with the presence of myotonia in patients. This set of CNBP alleles showed unimodal distribution with 25 different alleles ranging from 108 to 168 bp, in accordance with previous studies on European populations. The most frequent CNBP alleles consisted of 138, 134, 140, and 136 bps with an overall locus heterozygosity of 90%. Sequencing of 103 unexpanded CNBP alleles in DM2-positive patients revealed that (CCTG)5(NCTG)3(CCTG)7 and (CCTG)6(NCTG)3(CCTG)7 are the most common interruption motifs. We also characterized five CNBP premutated alleles with (CCTG)n repetitions from n = 36 to n = 53. However, the molecular and clinical consequences in our cohort of samples are not unequivocal. Data that emerged from this study are representative of the Italian population and are useful tools for National and European centers offering DM2 genetic testing and counseling.

Abstract
Hospital residency is stressful, with a risk of burnout. To assess the prevalence of burnout in medical and surgical residents and identify psycho-organizational and medical risk factors with a view to prevention. A transverse study was conducted in France between September 2018 and November 2018, targeting 633 hospital residents. A self-administered questionnaire was delivered by e-mail. Burnout was assessed on the Maslach Burnout Inventory, anxiety/depression on the Hospital Anxiety and Depression Scale (HAD) and stress on a visual analogue scale (VAS). Two-hundred and sixteen of the targeted residents (34%) responded. Twenty-three (12%) showed severe burnout in all three dimensions, severe loss of empathy being the most frequent. Almost one-third showed symptoms of anxiety. Residents exposed to psycho-organizational constraints (stress, time pressure, intense work rhythm) and/or with symptoms of anxiety/depression more frequently showed burnout. Prevention of burnout requires reinforced medical monitoring and reduced psycho-organizational constraints.

Abstract
Vogt-Koyanagi-Harada (VKH) is an autoimmune disease characterized by inflammation in tissues that contain melanocytes. We aimed to increase the knowledge regarding immunological pathways deregulated in VKH disease. We compared the percentages of circulating natural killer (NK), NK T and T cells expressing the activatory markers: CD16, CD69, NK group 2D (NKG2D), natural cytotoxicity triggering receptor 3 (Nkp30), natural cytotoxicity triggering receptor 1 (Nkp46) and the inhibitory marker: NK group 2 member A (NKG2A) in 10 active VKH patients, 20 control subjects (CTR) and seven patients with Behçet disease (BD) by flow cytometry. Cytotoxic potential of NK cells was determined through the degranulation marker CD107a expression after contact with K562 cells by flow cytometry. Moreover, plasmatic levels of 27 cytokines were determined with a multiplex bead-based assay. VKH patients showed higher percentages of NKG2Dpos NK and NK T cells versus CTR. The cytotoxic potential of NK cells induced by K562 cells was comparable between VKH patients and CTR. Finally, higher concentrations of interleukin (IL)-4, IL-5, IL-7, IL-17 and platelet-derived growth factor-subunits B (PDGF-bb) were detected in plasma of VKH patients versus CTR. The immune profile of VKH patients was similar to that of BD patients.

Abstract
BACKGROUND Obesity is a multifactorial condition and a major risk factor associated with several non-communicable diseases, such as cardiovascular disease, and with a higher risk of premature death and disability. Sex-specific factors have key roles and must be taken into consideration in studying occupational factors associated with the risk of obesity. The aim of this study was to investigate gender differences in body mass index (BMI) in a large cohort representative of Italian workers and, correlating this index with several demographic and occupational variables, to verify sex- and work-dependent differences in the risk of obesity. METHODS We utilized data from INSuLa, a cross-sectional, nationally representative survey of the Italian worker population conducted in 2013 by the Italian Workers' Compensation Authority to investigate health and safety at work. Analyses were run on a sample of 8000 Italian workers, aged from 16 to 64 years. Logistic regression models were employed to assess gender differences in the relation between occupational characteristics and BMI. We adjusted for age, education, variables related to health protection at work, and chronic conditions and diseases. RESULTS There were several significant differences in the BMI between males and females, linked to some occupational factors. For instance, female shift workers were 1.32 times (95% CI 1.11-1.57) more likely to be overweight or obese than normal-weight workers, and this association was maintained when controlling for confounders. The likelihood of overweight or obesity among women who worked 1-2 night shifts per week was significantly higher - 1.5-1.6 times - than those on day shifts. CONCLUSIONS Gender-specific differences in occupational factors associated with the risk of obesity are useful with a view to characterizing this risk and helping identify workplace-targeted intervention strategies.

Abstract
DM1 is an autosomal dominant multisystemic disease caused by an unstable CTG repeat expansion in the 3'-untranslated region (UTR) of the DMPK gene. The complex variant DMPK expanded the alleles containing CAG, CCG, CTC and/or GGC interruptions repetition sequences have been reported in 3-8% of DM1 patients. To date, very few information is available about the frequency and clinical consequences of pre-mutated DMPK variant allele. In this study, we describe a three-generation Italian family showing the segregation of an interrupted DMPK allele within the premutation range. TP-PCR with primers complementary to CCG repetitions and direct sequencing allow us to identify a hetero-triplet (CTG)6(CCGCTG)15(CTG)5 repeat structure. The haplotype analysis demonstrated that this variant allele is associated with the European founder DM1 haplotype. The pyrosequencing analysis of the CpG islands contained in the flanking regions of the CTG array, did not show the presence of a cis effect of the CCG interruptions on the methylation profile of the DM1 locus. The analysis of both meiotic transmissions, one maternal and one paternal, revealed the intrafamilial stability of the DM1 premutation among relatives. Our findings further support the hypothesis of a stabilizing effect of CCG interruptions on the mutational dynamics of the DM1 locus, also in intermediate DMPK alleles.

Abstract
PURPOSE Psychosocial consequences of road accidents are a major clinical problem that incurs significant social, occupational, and economic costs. The purpose of our study was to assess medical and socio-occupational factors of psychological distress in the severely injured 5 years after a road accident. METHODS A total of 691 of the 1168 subjects enrolled in a prospective cohort of road accident casualties (ESPARR cohort) responded to both standardized follow-up questionnaires at 1 and 5 years, assessing socio-occupational characteristics, physical and psychological sequelae, pain and perceived quality of life. RESULTS One quarter of participants exhibited psychological distress 5 years after the road accident; most of whom are women, with low educational level, and suffering from spinal lesions. After adjusting for several factors, psychological distress at 5 years was predicted by female gender and low educational level, and by several other factors observed 1 year after the road accident: poor self-reported quality of life, attention deficit and symptoms of anxiety. CONCLUSIONS Early-stage improvement in the screening and care of mental disorders in road accident casualties should help to reduce long-term psychological distress.

Abstract
BACKGROUND Higher Dietary Inflammatory Index (DII®) scores are associated with increased morbidity and mortality. However, little is known about the effects of DII on mortality in Mediterranean countries. Therefore, in the present study, we aimed to investigate the potential association between DII scores and overall, cancer and cardiovascular disease (CVD) mortality in people living in a Mediterranean area. METHODS DII scores were calculated using a validated food-frequency questionnaire. DII scores were then categorised into tertiles. Mortality was ascertained via death certificates. The association between DII scores with overall and cause-specific mortality was assessed via a multivariable Cox's regression analysis and reported as hazard ratios (HRs) with their 95% confidence intervals (CIs). RESULTS The study included 1565 participants (mean age 65.5 years; females 44.7%). After a median follow-up of 12 years (2005-2017), 366 (23.4%) participants died. After adjusting for 17 potential confounders, people with higher DII scores had an increased risk of death compared to those in the lowest (most anti-inflammatory) tertile (HR = 1.38; 95% CI = 1.04-1.82 for the second tertile; HR = 1.38; 95% CI = 1.03-1.86 for the third tertile). Each 1 SD increase in DII score increased the risk of death by 13%. No association was found between DII scores and cancer or CVD death when considered separately. CONCLUSIONS Higher DII scores were associated with a significantly higher mortality risk, whereas the association with cause-specific mortality was less clear. These findings highlight the potential importance of diet in modulating inflammation and preventing death.

Abstract
Bench press (i.e. arm-based) and half-squat (i.e. leg-based) are exercises commonly used to increase and evaluate muscular strength. In addition to differences in the location of the muscles that participate in each exercise, the total muscle mass required for the latter is larger than that involved in the former. The aim of this study is to analyze the effects of a maximal incremental strength test when performed by bench press and by half-squat on myocellular damage, oxidative damage and the inflammatory cytokine response. Ten male athletes were subjected to half-squat and bench press incremental strength tests. Blood samples were collected at rest, 15-minutes and 24 h post-test. Hydroperoxide and malondialdehyde concentrations were determined as lipid peroxidation markers. Lactate dehydrogenase (LDH) and creatine kinase isoenzyme MB (CK-MB) activities were determined as markers of muscle damage. α-Actin concentration was determined as a marker of sarcomeric damage. Serum interleukin (IL) 6, IL10, and tumor necrosis factor alpha (TNFα) were determined to assess the inflammatory response. LDH and CK-MB values were greater at 15 min and 24 h post bench press exercise (p < 0.05). No differences were found in lipid peroxidation or α-actin. Interestingly, IL10 values were greater in response to the press bench at 24 h post-test (p < 0.05). Our results suggest that, at equivalent workloads, an arm-based exercise induced higher anti-inflammatory effects and more severe muscle damage compared with a leg-based exercise.

Abstract
The identification of multilocus imprinting disturbances (MLID) appears fundamental to uncover molecular pathways underlying imprinting disorders (IDs) and to complete clinical diagnosis of patients. However, MLID genetic associated mechanisms remain largely unknown. To characterize MLID in Beckwith-Wiedemann (BWS) and Silver-Russell (SRS) syndromes, we profiled by MassARRAY the methylation of 12 imprinted differentially methylated regions (iDMRs) in 21 BWS and 7 SRS patients with chromosome 11p15.5 epimutations. MLID was identified in 50% of BWS and 29% of SRS patients as a maternal hypomethylation syndrome. By next-generation sequencing, we searched for putative MLID-causative mutations in genes involved in methylation establishment/maintenance and found two novel missense mutations possibly causative of MLID: one in NLRP2, affecting ADP binding and protein activity, and one in ZFP42, likely leading to loss of DNA binding specificity. Both variants were paternally inherited. In silico protein modelling allowed to define the functional effect of these mutations. We found that MLID is very frequent in BWS/SRS. In addition, since MLID-BWS patients in our cohort show a peculiar pattern of BWS-associated clinical signs, MLID test could be important for a comprehensive clinical assessment. Finally, we highlighted the possible involvement of ZFP42 variants in MLID development and confirmed NLRP2 as causative locus in BWS-MLID.

Abstract
Human induced pluripotent stem cells (hiPSCs)-patient specific are an innovative tool to reproduce a model of disease in vitro and summarize the pathological phenotype and the disease etiopathology. Myotonic dystrophy type 2 (DM2) is caused by an unstable (CCTG)n expansion in intron 1 of the CNBP gene, leading to a progressive multisystemic disease with muscle, heart and central nervous dysfunctions. The pathogenesis of CNS involvement in DM2 is poorly understood since no cellular or animal models fully recapitulate the molecular and clinical neurodegenerative phenotype of patients. In this study, we generated for the first time, two DM2 and two wild type hiPSC lines from dermal fibroblasts by polycistronic lentiviral vector (hSTEMCCA-loxP) expressing OCT4, SOX2, KLF4, and cMYC genes and containing loxP-sites, excisable by Cre recombinase. Specific morphological, molecular and immunocytochemical markers have confirmed the stemness of DM2 and wild type-derived hiPSCs. These cells are able to differentiate into neuronal population (NP) expressing tissue specific markers. hiPSCs-derived NP cells maintain (CCTG)n repeat expansion and intranuclear RNA foci exhibiting sequestration of MBNL1 protein, which are pathognomonic of the disease. DM2 hiPSCs represent an important tool for the study of CNS pathogenesis in patients, opening new perspectives for the development of cell-based therapies in the field of personalized medicine and drug screening.

Abstract
SummaryOxidized LDL has been observed to induce abnormalities in endothelial function which may be relevant for the progression of atherosclerotic lesions. We studied in vitro the possible effects of oxidized LDL on the antiaggregating activity of endothelial cells, which is dependent on release of prostacyclin and nitric oxide. We used an experimental model in which cultured human endothelial cells were placed in the aggregometer in contact with human platelets, after blockade of cyclo-oxygenase by adding acetylsalicylic acid. In this way the antiaggregant effect of endothelial cells was dependent on the release of nitric oxide alone; prevention of antiaggregant activity by preincubation of endothelial cells with 300 μM L-NG-mono-methyl-arginine confirmed this. When this system was used, endothelial cells (2–7.5 X 105ml) almost completely inhibited thrombin-induced (0.02–0.08 U/ml) platelet aggregation (2 × 108 platelets/ml), measured according to Born (11.1% ±8.5 vs 68.6% ±12.6, M ± SD). This antiaggregating activity was reduced when slightly oxidized LDL 100 μg/ml (35.2% ± 14.9, p <0.001), but not native LDL 100 μg/ml (7.5% ± 7.6), was added immediately before aggregation was induced.. Incubation of endothelial cells with oxidized LDL 100 μg/ml for 1 h did not affect the antiaggregating capacity, unless oxidized LDL was present during aggregation (18.3% ± 10.2 vs 35.8% ± 9.6, p <0.02). No significant direct effect of either oxidized or native LDL on stimulated platelet aggregation was observed. Our results indicate that slightly oxidized LDL can reduce the antiaggregating properties of the endothelium, probably by interaction with NO rather than through inhibition of its synthesis.

Abstract
BACKGROUND Road accidents may impact victims' physical and/or mental health and socio-occupational life, notably including return to work. OBJECTIVES To assess whether the occupational medical consequences sustained by subjects injured in road accidents occurring in a work-related context differ from those associated with private accidents. METHODS 778 adults who were in work or occupational training at the time of their accident were included. Two groups were distinguished: 354 (45.5%) injured in road accidents occurring in a work-related context (commuting or on duty) and 424 (54.5%) injured in a private accident. The groups were compared on medical and occupational factors assessed on prospective follow-up at 6 months and 1 and 3 years. Multivariate analysis explored for factors associated at 6 months and 1 year with sick leave following the accident and duration of sick leave. RESULTS There were no significant differences between groups for demographic data apart from a slightly higher injury severity in private accidents (32.5% of private accidents with MAIS3+(Maximum Abbreviated Injury Scale greater or equal to 3) vs. 23.7% for work-related accidents, p = 0.007). Victims of work-related accidents were more often on sick leave (OR = 1.8; 95% CI, 1.1-2.9). Although the length of sick leave is higher for work-related accidents that for private accidents, multivariate analysis showed that the injury severity and the post-traumatic stress disorder (PTSD) are significant factors to explain the time to return to work. There were no significant differences according to occupational impact during follow-up, notably including sick-leave duration, number of victims returning to work within 3 years and number of victims out of work due to incapacity. CONCLUSIONS In the ESPARR (follow-up study of a road-accident population in the Rhône administrative county: Etude de Suivi d'une Population d'Accidentés de la Route dans le Rhône) cohort, the fact that a road accident occurred in a work-related context did not affect the occupational consequences.

Abstract
Ten patients with hairy cell leukemia are being treated at our institution with a therapeutic schedule of α2(r) interferon (2 × 106 IU/m2 s.c. three times per week). Five patients underwent splenectomy from 4 to 108 months before treatment; nonsplenectomized patients had spleens palpable 6 to 12 cm UCM. According to Quesada's response criteria, at the sixth month of therapy, one patient was considered a complete responder, 8 partial responders and one a minor responder, with no differences between splenectomized and nonsplenectomized patients. In nonsplenectomized patients the spleen returned to normal. Our data confirm that interferon, even at low dosages, is a very effective approach for hairy cell leukemia. No evidence was found to contraindicate such therapy.

Abstract
The widespread industrial application of nanomaterials (NMs) has dramatically increased the likelihood of environmental and occupational exposure of humans to such xenobiotics. This issue, together with the increasing public health interest in understanding the effects of chemicals on endocrine system, encouraged to investigate the disruptive potential of NMs on the endocrine function. Therefore, the aim of this study was to evaluate the effects of palladium nanoparticles (Pd-NPs) on the female reproductive system of Wistar rats, intravenously exposed to different doses (0.12, 1.2, and 12 µg/kg), through the assessment of possible quantitative changes in the serum concentrations of several sex hormones. Our results demonstrated that the highest exposure doses significantly reduced the estradiol and testosterone concentrations, while increased the luteinizing hormone levels in treated animals compared to controls. Such alterations are indicative for an abnormal reproductive axis function. However, further investigations are needed to clarify the role of the different NP physicochemical properties in determining such effects, and possible underlining molecular mechanisms, as well as their relevance for the development of diseases in the female reproductive system. Overall, this may be helpful to define accurate risk assessment and management strategies to protect the health of the general and occupational populations exposed to Pd-NPs.

Abstract
Road accidents may impact victims' physical and/or mental health and socio-occupational life, particularly the capacity to return to work. The purpose of our study is to assess modifiable medical and socio-occupational factors of non-return to work in the severely injured 3 years after a road accident. Among1,168 road accidents casualties in the Rhône administrative Département of France followed for five years, 141 of the 222 severely injured (Maximal Abbreviated Injury Scale ≥ 3) aged more than 16 years who were in work at the time of the accident, reported whether they had returned to work in the 3 years following the accident. The subgroups of those who had (n=113) and had not returned to work (n=28) were compared for socio-occupational (gender, age, educational level, marital status, socio-occupational group) accident-related medical factors (type of road user, type of journey, responsibility in the accident, initial care) and post-accident medical factors (pain intensity, post-traumatic stress disorder, physical sequelae, quality of life) by using standardized tools. Severity of initial head, face and lower-limb injury, intense persistent pain, post-traumatic stress disorder, poor self-assessed quality of life and health status at 3 years were associated with non-return to work on univariate analysis. On multivariate analysis, severity of initial head and lower-limb injury, intense persistent pain at 3 years and post-traumatic stress disorder were significantly associated with non-return to work 3 years following severe road-accident injury. Post-traumatic stress disorder and chronic pain were essential modifiable medical determinants of non-return to work in the severely injured after a road accident: early adapted management could promote return to work in the severely injured. Improve early adapted treatment of pain and PTSD in the rehabilitation team should help the severely injured return to work following a road accident.

Abstract
Recently, palladium nanoparticles (PdNPs) have been increasingly used in many industrial sectors, and this has led to a significant release of nano-sized palladium particles into the environment. However, despite the increase in occupational and general population exposure, information on the potential adverse effects of these PdNPs is still limited and their impact on the immune system constitutes a major health concern. Therefore, the aim of this study was to investigate the potential adverse effects induced by subchronic intravenous administration of PdNPs on the immune system of female Wistar rats by evaluating alterations in Interleukin (IL)-1α, IL-2, IL-4, IL-6, IL-10, IL-12, granulocyte-macrophage colony-stimulating factor (GM-CSF), Interferon (INF)-γ, and Tumor Necrosis Factor (TNF)-α serum levels. Exposed and control animals were randomly divided into five groups (0, 0.012, 0.12, 1.2, and 12 μg PdNPs per kg body weight) which were treated with repeated intravenous injections of vehicle or PdNPs (on day 1, 30, and 60). Subchronic exposure to PdNPs induced a decreasing trend in serum levels in most of the cytokines investigated, with the highest concentration (12 μg/kg) determining significant inhibitory effects. Overall, these results showed that PdNPs are able to alter cytokine serum levels in subchronically treated Wistar rats, suggesting a possible impact of these xenobiotics on the immune system after long-term exposures.

Abstract
OBJECTIVE Ten to thirty percent of lung cancer is thought to be of occupational origin. Lung cancer is under-declared as an occupational disease in Europe, and most declarations of occupational disease concern asbestos. The purpose of this study was to design and validate a short, sensitive self-administered questionnaire, as an aid for physicians in detecting occupational exposure to asbestos and other lung carcinogens in order to remedy occupational lung cancer under-declaration. STUDY DESIGN Cross-sectional study. METHODS A short (30-question) self-administered questionnaire was drawn up by oncologist-pneumologists and occupational physicians, covering situations of exposure to proven and probable lung carcinogens. Understanding and acceptability were assessed on 15 lung cancer patients. Validity and reliability were assessed on 70 lung cancer patients by comparison against a semi-directive questionnaire considered as gold standard. Sensitivity and specificity were assessed by comparing responses to items on the two questionnaires. Reliability was assessed by analysing the kappa concordance coefficient for items on the two questionnaires. RESULTS Sensitivity was 0.85 and specificity 0.875. Concordance between responses on the two questionnaires was 85.7%, with a kappa coefficient of 0.695 [0.52-0.87]. Mean self-administration time was 3.1 min (versus 8.12 min to administer the gold-standard questionnaire). In 16 patients, the self-administered questionnaire detected lung carcinogen exposure meeting the criteria for occupational disease. CONCLUSION The present short, easy-to-use self-administered questionnaire should facilitate detection of occupational exposure to lung carcinogens. It could be used in occupational lung cancer screening and increase the presently low rate of application for recognition of lung cancer as an occupational disease.

Abstract
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian agenesis, is the second most common cause of primary amenorrhea. It is characterized by congenital absence of the uterus, cervix, and the upper part of the vagina in otherwise phenotypically normal 46,XX females. MRKH syndrome has an incidence of about 1 in 4,500-5,000 newborn females and it is generally divided into two subtypes: MRKH type 1, in which only the upper vagina, cervix and the uterus are affected, and MRKH type 2, which is associated with additional malformations generally affecting the renal and skeletal systems, and also includes MURCS (MÜllerian Renal Cervical Somite) characterized by cervico-thoracic defects. MRKH syndrome is mainly sporadic; however, familial cases have been described indicating that, at least in a subset of patients, MRKH may be an inherited disorder. The syndrome appears to demonstrate an autosomal dominant inheritance pattern, with incomplete penetrance and variable expressivity. The etiology of MRKH syndrome is still largely unknown, probably because of its intrinsic heterogeneity. Several candidate causative genes have been investigated, but to date only WNT4 has been associated with MRKH with hyperandrogenism. This review summarizes and discusses the clinical features and details progress to date in understanding the genetics of MRKH syndrome.

Abstract
BACKGROUND AND AIMS Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. METHODS AND RESULTS We studied 2573 people, aged 50-75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, vegetables, fruits, eggs, milk, vegetable oils, and added sugar, whereas men consumed more starchy foods, soft drinks and alcoholic beverages. This stands for a higher proportion (%) of energy intake from saturated fat and added sugar (12.0 ± 2.4 vs 11.5 ± 2.5 and 3.4 ± 3.2 vs 2.3 ± 3.2, P < 0.04), and a higher intake of fiber (11.2 ± 2.8 vs 10.4 ± 2.6 g/1000 Kcal/day) in women. Adherence to the recommendations for saturated fat and fiber consumption was associated with significantly lower LDL-cholesterol regardless of sex. Adherence to the recommendations for added sugars was associated with significantly lower triglycerides and higher HDL-cholesterol in men and women. CONCLUSIONS Men and women with diabetes show significant differences in adherence to nutritional recommendations, but sex differences in plasma lipid profile are unlikely to be explained by nutritional factors. Adherence to the nutritional recommendations is associated with a better plasma lipid profile regardless of sex, thus reinforcing the importance of substituting saturated for unsaturated fat sources, increasing fiber and reducing added sugar intake.

Abstract
“You are what you eat,” is a well-known axiom coined over 100 years ago by the French politician and epicure Jean Anthelme Brillat-Savarin. With this in mind, it is unsurprising that as diets across the United States and around the globe have become increasingly unhealthy, we have become unhealthy as well. Linked closely with the obesity epidemic, diabetes now affects over 29 million Americans (12.3% of adults over the age of 20). An additional 86 million Americans over the age of 20 are estimated to have pre-diabetes, making this disease an urgent health care problem.As type 2 diabetes is so closely associated with diet and obesity, it is possible that dietary interventions might prove more effective and affordable than pharmaceutical options. Reduced-calorie diets are notoriously difficult to sustain, but altering the macronutrient composition of the diet while keeping the total number of calories constant is an intriguing alternative. Recent findings suggest that a low protein, high carbohydrate diet can increase lifespan and improve metabolic health in rodents, yet the applicability of these studies to humans as well as the mechanisms driving this effect remain unclear.Here, we demonstrate for the first time in a randomized controlled trial that placing humans on a moderately protein restricted (PR) diet for one month improves multiple markers of metabolic health in humans, including fasting blood glucose and body mass index. We observed similar beneficial effects of moderate PR on the metabolic health of mice over the course of 3 months, with improved glucose tolerance starting as early as three weeks after initiation of the diet. While the precise dietary components altered in a PR diet that promote metabolic health have never been defined, we hypothesized that decreased levels of specific amino acids – the building blocks of protein – might mediate these effects.Several studies have shown that insulin-resistant humans have increased serum levels of the three branched-chain amino acids (BCAAs) – leucine, isoleucine, and valine. To study the contribution of reduced BCAAs to the beneficial effects of a PR diet, we placed mice on one of four amino acid (AA) defined diets: Control (21% of calories from AAs), Low AA (7% of calories from AAs), a Low BCAA diet in which the level of the three BCAAs was the same as in the Low AA (7%) diet, but all other AAs were at the level of a Control (21%) diet; and a Low Leucine diet in which only the level of leucine was reduced by 2/3rds. The caloric density of the diet as well as dietary fat was kept constant. We tracked weight and body composition over the course of three months, periodically testing glycemic control through the use of glucose, insulin, and pyruvate tolerance tests and the analysis of circulating hormones. At the end of the experiment, we isolated islets for the ex vivo analysis of glucose stimulated insulin secretion, and collected tissues and blood for subsequent phosphoproteomic and genomic analysis.We find that a specific reduction in dietary branched chain amino acids (BCAAs) is sufficient to improve glucose tolerance and body composition equivalently to a PR diet in mice. Intriguingly, the improved metabolic health of mice fed a low BCAA diet is independent of increased FGF21, an insulin sensitizing hormone believed to be responsible for many of the positive metabolic effects of a PR diet. Switching mice induced to be obese and insulin resistant through high-fat diet feeding to a diet with reduced levels of BCAAs stimulates rapid improvements in glucose tolerance and fat mass loss. Our results highlight a critical role for dietary quality in glycemic control, and suggest that a reduction of dietary BCAAs, or pharmacological interventions in this pathway, may offer a novel and translatable therapy to promote metabolic health.

Abstract
OBJECTIVES The present study sought to quantify the impaired mental well-being and psychosocial stress experienced by nursing home staff and to determine the relationship between impaired mental well-being assessed on the 12-item General Health Questionnaire (GHQ-12) and exposure to psychosocial stress assessed on Siegrist's effort/reward and overcommitment model. METHODS A transverse study was conducted in France on 2471 female employees in 105 nursing homes for the elderly. Personal and occupational data were collected by questionnaire for 668 housekeepers, 1454 nursing assistants and 349 nurses. RESULTS 36.8% of participants (n=896) showed impaired mental well-being, 42.7% (n=1039) overcommitment and 9% (n=224) effort/reward imbalance. Overcommitment (prevalence ratio (PR)=1.27; 95% CI (1.21 to 1.34)) and effort-reward imbalance (PR=1.19; 95% CI (1.12 to 1.27)) were significantly associated with presence of impaired mental well-being after adjustment for personal factors (age and private life events). Taking effort and reward levels into account, the frequency of impaired mental well-being was highest in case of exposure to great extrinsic effort and low rewards of any type: esteem, PR=3.53, 95% CI (3.06 to 4.08); earnings, PR=3.48, 95% CI (2.99 to 4.06); or job security, PR=3.30, 95% CI (2.88 to 3.78). Participants in situations of overcommitment and of effort/reward imbalance were at the highest risk of impaired mental well-being: PR=3.86, 95% CI (3.42 to 4.35). CONCLUSIONS Several changes in nursing home organisation can be suggested to reduce staff exposure to factors of psychosocial stress. Qualitative studies of the relation between impaired mental well-being and psychosocial stress in nursing home staff could guide prevention of impaired mental well-being at work.

Abstract
MAP/microtubule affinity-regulating kinase 4 (MARK4) is a serine-threonine kinase that phosphorylates microtubule-associated proteins taking part in the regulation of microtubule dynamics. MARK4 is expressed in two spliced isoforms characterized by inclusion (MARK4S) or exclusion (MARK4L) of exon 16. The distinct expression profiles in the central nervous system and their imbalance in gliomas point to roles of MARK4L and MARK4S in cell proliferation and cell differentiation, respectively. Having ruled out mutations and transcription defects, we hypothesized that alterations in the expression of splicing factors may underlie deregulated MARK4 expression in gliomas. Bioinformatic analysis revealed four putative polypyrimidine-tract binding (PTB) protein binding sites in MARK4 introns 15 and 16. Glioma tissues and glioblastoma-derived cancer stem cells showed, compared with normal brain, significant overexpression of PTB, correlated with high MARK4L mRNA expression. Splicing minigene assays revealed a functional intronic splicing silencer in MARK4 intron 15, but mutagenesis of the PTB binding site in this region did not affect minigene splicing, suggesting that PTB may bind to a splicing silencer other than the predicted one and synergistically acting with the other predicted PTB sites. Electrophoretic mobility shift assays coupled with mass spectrometry confirmed binding of PTB to the polypyrimidine tract of intron 15, and thus its involvement in MARK4 alternative splicing. This finding, along with evidence of PTB overexpression in gliomas and glioblastoma-derived cancer stem cells and differentiated progeny, merged in pointing out the involvement of PTB in the switch to MARK4L, consistent with its established role in driving oncogenic splicing in brain tumors.

Abstract
Silver nanoparticles (AgNPs) functionalized with an organometallic bifunctional thiol containing Pt(ii) centers, generated in situ from trans-trans-[thioacetyl-bistributylphosphine-diethynylbiphenyl-diplatinum(ii)], were synthesized with different sulphur/metal molar ratios (i.e. AgNPs-1 and AgNPs-2) with the aim to obtain nanosystems of different mean size and self-organization behaviour. AgNPs spontaneously self-assemble, giving rise to 2D networks, as previously assessed. In this work a deeper insight into the chemico-physical properties of these AgNPs is proposed by means of synchrotron radiation induced X-ray photoelectron spectroscopy (SR-XPS) and X-ray absorption fine structure spectroscopy (XAFS) techniques. The results are discussed in order to probe the interaction at the interface between a noble metal and a thiol ligand at the atomic level and the aim of this study is to shed light on the chemical structure and self-organization details of nanosystems. The nature of the chemical interaction between the dithiol ligand and the Ag atoms on the nanoparticle surface was investigated by combining SR-XPS (S2p, Ag3d core levels) and XAS (S and Ag K-edges) analysis. UV-visible absorption and emission measurements were also carried out on all samples and compared with TD-DFT calculations so as to get a better understanding of their optical behavior and establish the nature of the excitation and emission processes.

Abstract
BACKGROUND Few studies have been published about the factors influencing return to work after sickness absence. AIMS To identify medical and occupational factors influencing the type of fitness certificate given by occupational physicians before employees return to work after sickness absence. METHODS A cross-sectional study was undertaken over 3 months in several health services in France. Workers undergoing a medical examination before returning to work after a period of sickness absence of at least 3 weeks were included. Medical and occupational factors were collected using a questionnaire. The relationship between different factors and certification of fitness was assessed by univariate and multivariate analyses. RESULTS Among the 402 workers included, 64% were considered fit to return to work. Being older, strenuous work, prolonged sick leave and fear of returning to work appeared to be negative factors influencing the return to a previous job. In contrast, having an education level higher than secondary school, being satisfied at work, perception of very good health and benefitting from satisfactory professional relationships appeared to favour return to work. We developed a predictive score of not being fit to return to work after illness. CONCLUSIONS Our study highlighted the relationship between medical and occupational factors with problems returning to work. The predictive score may be used by occupational physicians as a screening tool to identify those who are likely to have difficulties returning to work after illness, so that their working conditions can be modified to take this into consideration.

Abstract
AIMS The aim of this consensus paper is to review the available evidence on the association between moderate alcohol use, health and disease and to provide a working document to the scientific and health professional communities. DATA SYNTHESIS In healthy adults and in the elderly, spontaneous consumption of alcoholic beverages within 30 g ethanol/d for men and 15 g/d for women is to be considered acceptable and do not deserve intervention by the primary care physician or the health professional in charge. Patients with increased risk for specific diseases, for example, women with familiar history of breast cancer, or subjects with familiar history of early cardiovascular disease, or cardiovascular patients should discuss with their physician their drinking habits. No abstainer should be advised to drink for health reasons. Alcohol use must be discouraged in specific physiological or personal situations or in selected age classes (children and adolescents, pregnant and lactating women and recovering alcoholics). Moreover, the possible interactions between alcohol and acute or chronic drug use must be discussed with the primary care physician. CONCLUSIONS The choice to consume alcohol should be based on individual considerations, taking into account the influence on health and diet, the risk of alcoholism and abuse, the effect on behaviour and other factors that may vary with age and lifestyle. Moderation in drinking and development of an associated lifestyle culture should be fostered.

Abstract
The diffusion of window frames with low air permeability, due to the energy saving regulations, has implied in several cases the worsening of the indoor microclimate and air quality. On the other hand, air-tight window frames imply uncontrolled and too high air change rates. The mechanical ventilation not always is a practicable solution because of economic reasons and because it implies energy waste. Various Italian and European environmental and energetic laws take into consideration and promote the use of controlled natural ventilation, though this definition is not associated to well defined and tested technical solutions. An adequate solution can be achieved by using semi-passive self adjustable ventilation devices, able to ensure controlled changes of indoor air. In this paper, a semi-passive damper with a feedback control system is proposed and its behavior is investigated by means of experimental study. The presented semi-passive grille allows to control the air flow rate, injected into the room by natural or artificial pressure gradient, more effectively than the usual passive ventilation grilles made available by the present industrial production. However, since the semi-passive grille has a one-way flow, in the natural ventilation of a flat the proper functioning of the system could be ensured with a more complex configuration, with respect to the passive self-regulating grilles, able to limit the flow of fresh air in the presence of high levels of Δp; conversely, it could have widespread use in applications requiring a more accurate control of airflow in case of mechanical ventilation plants.

Abstract
BACKGROUND AND OBJECTIVE Recent rapid advances in nanotechnology raise concerns about development, production route, and diffusion in industrial and consumer products of titanium dioxide nanoparticles (TiO2-NPs). In fact, compared to recent increase in applications of this nanomaterial, the health effects of human exposure have not been systematically investigated. The aim of this review was to provide a comprehensive overview on the current knowledge regarding the effects of TiO2-NPs on mammalian cells. EVIDENCE AND INFORMATION SOURCES This review is based on an analysis of the current literature on this topic. STATE OF THE ART Fine TiO2 particles have been considered as safe and to pose little risk to humans, suggesting that exposure to this material is relatively harmless. However, available data in the literature showed that TiO2-NPs can cause several adverse effects on mammalian cells such as increase of reactive oxygen species (ROS) production and cytokines levels, reduction of cell viability and proliferation, induction of apoptosis and genotoxicity. PERSPECTIVES AND CONCLUSIONS Additional research is needed to obtain up-to-date knowledge on health effects of TiO2-NPs and to avoid any potential risk correlated to their exposure. Consequently, future studies need to: (1) use an homogeneous and rigorous exposure classification to clarify how the physicochemical properties of TiO2-NPs correlate with their toxicological effects; (2) assess the potential adverse effects of low level exposures to TiO2-NPs, as most of the information currently available originates from studies in which exposure levels were excessively and unrealistically high; (3) identify the possible roles of TiO2-NPs in genotoxicity and carcinogenicity (4) carry out epidemiologic studies of exposed workers to provide an assessment of possible risks correlated to the occupational exposure to TiO2-NPs.
