Abstract
INTRODUCTION Telomeres are composed of a repeated sequence of double-stranded nucleotides TTAGGG and numerous proteins including the Shelterin complex. Their main role is to maintain the stability of the genome during cell replication through a mechanism of copying the repeted sequence by the telomerase complexe. All the diseases involving a deregulation of this complex are now grouped together under the term telomeropathies. They are difficult to diagnose and manage. Our objective was to describe the clinico-biological characteristics and treatments used, in patients affected by telomeropathies previously seen by an hematologist followed at the Lille University Hospital Center. METHODS This is a retrospective, single-center study carried out within the department of internal medicine-clinical immunology, Reference center for rare autoimmune and systemic diseases at Lille University Hospital Center between 2005 and 2020 including all patients followed for telomeropathy. RESULTS Probands and relatives were included. Fifteen patients were studied from 10 independant families. Sixty percent had an heterozygous TERC gene mutation. Sixty seven percent had haematological diseases including macrocytosis, anemia and/or thrombocytopenia, 20 % had a fibrotic hepatic disease, 27 % had a fibrotic pulmonary disease. Lymphocyte immunophenotyping showed a double negative T lymphocyte population with γδ TCR expression in 5 (33 %) patients. Forty-seven percent of the patients had not received any treatment. Twenty-seven percent were on androgen therapy. Twenty percent had received cyclosporine and 13 % anti-lymphocyte serum in the context of initial misdiagnosis. CONCLUSION It is important to be aware of the complexity of telomeropathies, a differential diagnosis of immune aplastic anemia, in order to optimize management and avoid inappropriate treatments. Allografting of hematopoietic stem cells is the only potentially curative treatment. Our analysis found particularities in immunophenotyping lymphocyte not previously described to our knowledge, whose physiopathological imputability remains to be demonstrated.

Abstract
Issue For several weeks, prophylactic messages against the extension of Covid-19 have saturated the public space. To protect populations, efficient measures have been rapidly put to limit the movement of people and manufactured goods. These policies have reduced global greenhouse gas emissions as well as air pollution, especially in China. Problem If climate change were an epidemic, we would probably have already restored it. But it results directly from the thermo-industrial activities linked to the consumption society. For Friel (Lancet, 2020), the dramatic consequences of this disturbances have to be considered as an essential health issue. She advocates for 'climate change and health alliances'. Results Within such alliances, health professionals have the responsibility (1) to describe the morbidity inherent in our thermo-industrial societies (2) to alert populations, and (3) to work with allies to tackle climate change and protect human populations, starting with the most vulnerable. This type of alliance is underway in the battle against air pollution, as it has been for years for fighting smoking. Alliances are intended to extend to all population health issues, with a complete decompartmentalization of minds and practices at large scale. Lessons Health professionals have to be mindful not to cause any harm while practicing. The health system alone produces up to 8% of global greenhouse gas in developed countries (Pichler, 2019; HCWH, 2019). There is room for action. Since 2009, the British health care system (NHS) has adopted an efficient decarbonation policy, reducing global emission from 8 to 4%, but this outstanding initiative remains an exception worldwide. Key messages A review of public health strategies is necessary to meet the energy, environmental and health issues, both in terms of health risks due to climate change and of decarbonation of care activities. Health professionals have the responsibility to alert populations and to work with allies to tackle climate change and protect human populations.

Abstract
The induction of the granulocytic differentiation of leukemic cells by all-trans retinoic acid (RA) has been a major breakthrough in terms of survival for acute promyelocytic leukemia (APL) patients. Here we highlight the synergism and the underlying novel mechanism between RA and the granulocyte colony-stimulating factor (G-CSF) to restore differentiation of RA-refractory APL blasts. First, we show that in RA-refractory APL cells (UF-1 cell line), PML-RA receptor alpha (RARα) is not released from target promoters in response to RA, resulting in the maintenance of chromatin repression. Consequently, RARα cannot be recruited, and the RA target genes are not activated. We then deciphered how the combination of G-CSF and RA successfully restored the activation of RA target genes to levels achieved in RA-sensitive APL cells. We demonstrate that G-CSF restores RARα recruitment to target gene promoters through the activation of the extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) pathway and the subsequent derepression of chromatin. Thus, combinatorial activation of cytokines and RARs potentiates transcriptional activity through epigenetic modifications induced by specific signaling pathways.

Abstract
Inherited diseases and metabolism inborn errors with hematologic abnormalities such as cytopenias are observed early in the infant or childhood. Most of them require an acute observation of the bone marrow to determine quantitative and qualitative morphological peculiarities of each cell line in order to charatherize cytological signs of these childhood hereditary diseases and differentiate them from acquired disorders, which are particularly frequent in pediatric. So, after a brief review of hematopoietic physiology in healthy neonates and infant, we'll consider the physiopathology and bone marrow aspect of the erythroid (Blackfan-Diamond anemia, congenital dyserythropoietic...), megacaryocytic (Wiskott-Aldrich syndrome, congenital amegakaryocytic thrombocytopenia...) and granulocytic cell line (Kostmann syndrome, WHIM syndrome...) in hereditary disorder. Considering the hematologic consequences of metabolism inborn errors and storage diseases, the last part of this review will be dedicated to the examination of the bone marrow encountered in those diseases such as mitochondrial cytopathy, orotic aciduria or lysinuric aciduria intolerance.

Abstract
OBJECTIVE To evaluate the prevalence, characteristics, and treatment of restless legs syndrome (RLS) in France. METHODS In this population-based survey, face-to-face home interviews were conducted among a random sample of 10,263 French adults. A French translation of the four features defined by the International RLS Study Group in 1995 was used to assess the prevalence of symptoms consistent with a diagnosis of RLS. Data on severity of symptoms and their management were also collected. RESULTS The 12-month prevalence of RLS symptoms in the French adult population was estimated to be 8.5% (95% CI 8.0%, 9.0%), with a higher prevalence (p < 0.001) observed in women (10.8%) than in men (5.8%). Prevalence increases with age until 64 years and decreases thereafter in both sexes. Half of the identified subjects reported symptoms once a week at least. Symptoms were more severe in subjects reporting symptoms once a week at least compared to subjects with less frequent symptoms. In this group, half of the subjects reported a family history, the age at onset was earlier, and severity of symptoms higher. RLS had been previously diagnosed in only 5.3% of the subjects who reported previous medical diagnosis, and recommended RLS drug treatment was received by 3.4% of the 28.7% currently treated subjects. CONCLUSIONS Restless legs syndrome (RLS) occurred in 10% of women and 5% of men. RLS prevalence decreases after the age of 64. RLS is often underdiagnosed and few subjects receive recommended RLS drug treatment.

Abstract
OBJECTIVE To assess the efficacy, safety, and tolerability of ropinirole in the treatment of patients with restless legs syndrome. METHODS A 12 week, prospective, double blind, randomised comparison involving 284 patients from 10 European countries. All participants had a score of > or =15 on the international restless legs scale (IRLS). Patients were randomised (1:1) to receive either ropinirole 0.25-4.0 mg once daily or placebo. The primary efficacy end point was mean change from baseline to week 12 in total IRLS score. Global improvements (clinical global impression (CGI) scale) and improvements in sleep, health related quality of life (QoL; using generic and disease specific measures), work, and other activities were also assessed. RESULTS 112/146 patients (76.7%) taking ropinirole and 109/138 (79.0%) taking placebo completed the study. Improvement in IRLS at week 12 with ropinirole (mean (SD) dose, 1.90 (1.13) mg/day) was greater than with placebo (mean (SE): -11.04 (0.719) v -8.03 (0.738) points; adjusted difference = -3.01 (95% confidence interval (CI), -5.03 to -0.99); p = 0.0036). More patients in the ropinirole group (53.4%) showed improvement on the CGI scale at week 12 than in the placebo group (40.9%; adjusted odds ratio = 1.7 (1.02 to 2.69); p = 0.0416). Significant differences on both IRLS and CGI scales favouring ropinirole were apparent by week 1. Ropinirole was also associated with significantly greater improvements in sleep and QoL end points. The most common adverse events were nausea and headache. CONCLUSIONS Ropinirole improves restless legs syndrome compared with placebo, with benefits apparent by week 1. It is generally well tolerated.

Abstract
Delayed sleep phase syndrome involves undesirable late bed times and arising times with extreme difficulties in falling asleep and in awakening at a desired clock time. These patients present a delayed circadian system. Chronotherapy and phototherapy are designed to have a training effect on the circadian system. Response to these treatments varies widely and depends on the patient's motivation and associated psychological disorders. Other treatments have been proposed with less evident results. The few studies testing the effect of melatonin in delayed sleep phase syndrome concern a small number of patients and present methodological drawbacks. It can be concluded from these studies however that exogenous melatonin influences endogenous secretion more than other secretion rhythms. The effect on sleep time is significant but clinically moderate. More studies are needed to examine the effect of exogenous melatonin as a treatment strategy in delayed sleep phase syndrome.

Abstract
In this paper, we compare and analyze the results from automatic analysis and visual scoring of nocturnal sleep recordings. The validation is based on a sleep recording set of 60 subjects (33 males and 27 females), consisting of three groups: 20 normal controls subjects, 20 depressed patients and 20 insomniac patients treated with a benzodiazepine. The inter-expert variability estimated from these 60 recordings (61,949 epochs) indicated an average agreement rate of 87.5% between two experts on the basis of 30-second epochs. The automatic scoring system, compared in the same way with one expert, achieved an average agreement rate of 82.3%, without expert supervision. By adding expert supervision for ambiguous and unknown epochs, detected by computation of an uncertainty index and unknown rejection, the automatic/expert agreement grew from 82.3% to 90%, with supervision over only 20% of the night. Bearing in mind the composition and the size of the test sample, the automated sleep staging system achieved a satisfactory performance level and may be considered a useful alternative to visual sleep stage scoring for large-scale investigations of human sleep.

Abstract
The goal of the present study was to evaluate the first-night effect in psychiatric inpatients using large subject samples (n > 30) in order to obtain a good statistical evaluation. Thirty-two normal subjects and 94 psychiatric inpatients (38 depressives and 56 insomniacs) were studied for three consecutive nights in the hospital sleep laboratory. Our results showed clearly that there was a first-night effect in normal subjects, similar to that reported in previously published data, characterized by a longer rapid eye movement (REM) sleep latency (p < 0.05), increased wakefulness (p < 0.01) and total sleep time (p < 0.02) and a decreased sleep efficiency (p < 0.01). REM sleep latency and stage REM in the first third of the night were still altered in the second night. Both clinical groups had a less marked first-night effect than normal subjects, showing alterations only observed in REM sleep (p < 0.01) (decreased REM sleep, longer REM sleep latency, increased REM sleep gravity center). However, the first-night effect was more pronounced in insomniacs than in depressed patients. No statistical differences between the second and third nights' recordings were found in sleep parameters. It is suggested that first-night data should not be simply discarded but could be used in subsequent analyses.

Abstract
Antidepressant drugs, such as the tricyclics and the serotonin reuptake inhibitors, are well known to decrease paradoxical sleep and occasionally increase slow wave sleep in human and in animals. In order to examine whether amoxapine (a mixed NA reuptake blocker and 5-HT2/5-HT3 antagonist) and cericlamine (a selective 5-HT reuptake inhibitor) exert the same effect in rats, and to investigate the possible relationships between sleep, the action of antidepressants and the serotoninergic system, the effects of these two different drugs were examined under acute and chronic conditions. Acutely, amoxapine (1, 5 and 10 mg/kg; i.p.) and cericlamine (1, 8, 16 and 32 mg/kg; i.p.) decreased paradoxical sleep and increased deep slow wave sleep especially when they were given at a low dose. When administered for 14 days, amoxapine induced a sustained decrease of paradoxical sleep during the whole treatment, while some tolerance was observed with regard to the inhibitory effect of cericlamine on this state of sleep. In addition, a rebound of paradoxical sleep occurred on the first day of cericlamine withdrawal. Thus, amoxapine and cericlamine exerted the same effects on the states of vigilance in the rat as do other antidepressants. The effects of cericlamine on sleep probably reflect its blocking action on 5-HT uptake, whereas the more complex effects of amoxapine might involve its 5-HT2/5-HT3 antagonist properties.

Abstract
The effects of ipsapirone, a ligand of the 5-HT1A receptors and a new potential anxiolytic, on sleep/wakefulness regulation were examined in the rat. Injected i.p. at 1, 3 and 5 mg kg-1, this compound induced a dose-dependent reduction of paradoxical sleep for 2 to 4 hours, followed, at a dose of 5 mg kg-1, by a secondary rebound. The other states of vigilance were not modified, except at the latter dose where the amounts of wakefulness were enhanced initially and decreased secondarily, while those of SWS were enhanced from 2 to 4 hours post-treatment. The effects of ipsapirone (3 mg kg-1) persisted after infusion of the neurotoxin 5,7-dihydroxytryptamine into the dorsal raphe nucleus which induced the sub-total destruction of the serotoninergic system. Thus, the action of the 5-HT1A agonist ipsapirone on sleep/wakefulness cycles probably involves the stimulation of the post-synaptic 5-HT1A receptors.

Abstract
We describe a 29-year-old patient who developed acute colitis limited to the sigmoid and left colon with features mimicking ischemic injury after a prolonged administration of trifluoroperazine and levomepromazine, two phenothiazines in association with haloperidol, another neuroleptic, and biperidene, an anticholinergic compound. The discontinuation of these drugs was followed by a prompt and complete recovery, and no other cause of acute colitis was found. The subsequent administration of sultopride, a neuroleptic from the benzamide family and then the readministration of haloperidol were well tolerated. No colonic disorder occurred for the following months. This case strongly supports the view that neuroleptic agents, in particular phenothiazines, may induce acute colitis and that haloperidol, a butyrophenone derivative, or sultopride, a benzamide-related neuroleptic, can be administered thereafter without recurrence of the disease.
