4 and 128.2 mg/L, respectively. Moreover, suspended-solid phase cultivation significantly mitigated the growth inhibition caused by MIT toxicity, enabled the algae to completely biodegrade MIT of extremely high concentrations (4.7 mg/L and 11.4 mg/L) in a short time. Our results demonstrate the feasibility of suspended-solid phase algal cultivation for simultaneously and effectively removing multiple main contaminants from ROC. Starting up or recovering partial nitritation is a major challenge for achieving or maintaining stable partial nitritation/anammox (PN/A) during mainstream wastewater treatment. This study presents a novel strategy for recovering the nitrite pathway by selectively reviving ammonium oxidizing bacteria (AOB) after thoroughly inhibiting AOB and nitrite oxidizing bacteria (NOB) using free nitrous acid (FNA). A sequencing batch reactor was operated for PN/A to treat real domestic wastewater for 423 days, during which twice FNA treatment was temporarily implemented. Results showed that with a single 0.45 mg/L FNA treatment on flocculent sludge, the NO3--N concentration during the aerobic period showed an uptrend again and the partial nitritation performance was deteriorated. In contrast, 1.35 mg/L FNA treatment induced the inhibition of both AOB and NOB leading to regressive ammonium oxidation, but a subsequently higher DO (1.5 mg/L) and longer aeration duration recovered partial nitritation. For the relative abundances of the acquired biomass related to nitrogen conversion, Nitrosomonas, Nitrospira and Nitrolancea increased to 9.65%, 10.27% and 4.35%, respectively, at the beginning of the 1.35 mg/L FNA treatment, and Nitrospira and Nitrolancea decreased to 2.80% and 0.03% whereas Nitrosomonas declined to 8.71% after 76 days. Ca. Brocadia showed less resilience after the 1.35 mg/L FNA treatment, with the relative abundance decreasing from 13.38% to 0.62% due to insufficient nitrite. Molecular ecological network analysis indicates that among anammox taxa, Ca. Kuenenia and Ca. Brocadia formed important links with other N cycle processes. Moreover, the proposed strategy shows operational flexibility because it can be easily used to control NOB in mainstream PN/A applications offered by flocculent sludge systems. BACKGROUND With the surge of intervention research examining ways of supporting students with autism spectrum disorder (ASD) in inclusive settings, there remains a need to examine how technology supports could enhance students' learning by offering one size fits one instruction. Furthermore, intervention studies focused on teaching students with ASD how to solve fractions are scarce. AIMS The purpose of this research study was to examine the effects of providing instruction via video modeling (VM), concrete manipulatives, a self-monitoring checklist, and practice for comprehension check on the accuracy of fraction problem solving of three middle school students with ASD. see more METHODS AND PROCEDURES Through the use of single-case multiple probe across students experimental design, we examined whether a functional relation existed between the intervention and students' improved accuracy of solving simple proper fraction problems. OUTCOMES AND RESULTS All three students improved the accuracy of solving simple proper fraction problems from baseline to intervention sessions and two students generalized the skill to solving whole proper fraction problems. CONCLUSIONS AND IMPLICATIONS The intervention consisting of VM and concrete manipulatives along with additional behavioral strategies offers an option for teachers to accommodate diverse learning needs of students with ASD in a variety of settings. BACKGROUND Children with sensory processing challenges often demonstrate a specific vestibular dysfunction characterized by an irrational fear of movement experiences referred to as gravitational insecurity. PROCEDURES/OUTCOMES This descriptive, exploratory study of existing de-identified data examined characteristics and prevalence of symptoms indicative of gravitational insecurity and the relationship among gravitational insecurity, gender, age, and other types of sensory-motor problems in 689 children, aged 4-12 years, with Sensory Processing Disorder (SPD) and related parent-reported co-morbid diagnoses of Attention Deficit-Hyperactivity Disorder, Anxiety Disorder, Learning Disabilities and Autism Spectrum Disorder. Gravitational insecurity was identified by the sum of eight items on a parent-report clinical questionnaire of sensory processing and motor skills in children. RESULTS/CONCLUSIONS The number and patterns of gravitational insecurity symptoms were not significantly different across age, gender or comorbid diagnoses. Prevalence of symptoms of gravitational insecurity in a clinical population of children with SPD was 15 - 21%. Cluster analysis found two groups with and without gravitational insecurity. In the gravitational insecurity group all eight items examined occurred "sometimes/often" and four or more symptoms were reported by individuals in this group. IMPLICATIONS Gravitational insecurity is an important vestibular-based dysfunction to identify and treat in children with SPD. Future studies should examine the relationship between these symptoms and objective measures of gravitational insecurity. OBJECTIVE To review and describe available pharmacotherapy interventions for smoking cessation during pregnancy  nicotine replacement therapy (NRT) and non nicotine replacement therapy. METHODS The PubMed, Medline, and Cochrane databases (1/01/2003 au 5/04/2019) were accessed to identify relevant studies, using the search terms « Tobacco Use Cessation Devices", "nicotine replacement product or therapy", "smoking cessation", "Pregnancy", "pregnant women", "varenicline", "bupropion". Résults There is no data on the impact of NRT on the rate of smoking cessation during pre conception period. According to randomised studies versus placebo, the prescription of NRT during pregnancy (16-hours patches and gums being mainly studied) is not associated with smoking cessation during pregnancy or at the end of pregnancy (LE1). Based on the analysis of all available studies, the prescription of NRT during pregnancy is associated with smoking cessation during pregnancy and at the end of pregnancy (LE2). Co-administration ofient data and low level of evidence to assess the impact of bupropion during the three trimesters of pregnancy, and in particular the neonatal consequences. Because of its amphetamine properties, bupoprion is not recommended for smoking cessation assistance in pregnant women (GRADE C). The available data are very inadequate and low level of evidence to assess the impact of varenicline during pregnancy. For this reason, varenicline cannot be recommended for smoking cessation during pregnancy (professional consensus). CONCLUSIONS The prescription of NRT may be offered to any pregnant woman who has failed a spontaneous smoking cessation without NRT, taking into account the lower risks of premature birth in the case of NRT (GRADE B). link2 This prescription can be initiated by the professional taking care of the pregnant woman in early pregnancy (Professional consensus). Smoking during pregnancy is a public health problem. Individual screening is carried out in France during pregnancy consultations, followed by non-systemic care (with or without nicotine replacement therapy). In the UK, pregnant smokers are routinely screened during pregnancy follow-up and then referred to smoking cessation services. In order to improve their adherence, and smoking cessation, patients can be contacted, in particular by phone. We therefore recommend to systematically screen for smoking during pregnancy by asking the question of smoking or by measuring the CO exhaled during the various consultations, to offer care in collaboration with a local smoking cessation service and renew the requests if necessary. We need to develop these care networks in France. link3 Nicotine is the main addictive substance in tobacco and its addictive effects mainly involve dopamine. Nicotine is mainly metabolized (C-oxidation) in the liver to cotinine by the cytochrome P450 enzyme system. Nicotine half-life is short being about 2 hours.Nicotine metabolism appears to be increased during pregnancy, mainly due to an increased cytochrome activity and maternal cardiac output. Thus, the smoking behavior of the pregnant woman is subsequently modified with an increase in withdrawal syndromes and an increased desire to smoke. These pharmacological elements should be taken into account when prescribing nicotine replacement therapy.Regarding the markers of tobacco intoxication, there is a good correlation between the importance of smoking and the measurement of expired air carbon monoxide. Although there is no evidence of decreased obstetrical complications related to its use, it is simple and non-invasive and therefore may be useful in routine practice. It gives an instantaneous value of tobacco intoxication, and represents a starting point for dialogue and management and can help to highlight the reality of withdrawal.Regarding the evaluation of tobacco addiction, the most commonly used questionnaires are the Fagerström tests (FTCD, HSI...), which are well correlated with cotinine concentration. However, there is insufficient evidence of their usefulness in reducing tobacco consumption during pregnancy to recommend them in current practice.DSM-V diagnostic criteria for addiction should be known as they can also be used to characterize the intensity of this addiction. INTRODUCTION The consequences of smoking have been studied more during pregnancy than during breastfeeding. There is a passage of nicotine and other substances in breast milk and some modifications of milk composition. The objectives of this chapter are to study the benefits of breastfeeding in women who smoke, and the adaptation of smoking, medication and behavioral habits in case of incomplete withdrawal to better guide women. METHODS The MedLine database, the Cochrane Library and foreign guidelines from 1999 to 2019 have been consulted. RESULTS The conservation of the benefit of breastfeeding in smokers with regard to the prevention of respiratory infections, infantile colic, cognitive deficits, obesity, sudden infant death, is not known to date. It is therefore not recommended to include smoking status in the choice of feeding mode for the newborn (Professional Agreement). However, since breastfeeding is a factor associated with a reduction in smoking and / or withdrawal (NP2), it is recommended to promote breastfeeding in non-weaned women in order to limit smoking (grade B). The use of nicotine replacement therapy is possible during breastfeeding (Professional Agreement). In the absence of data, bupropion (Zyban®) and varenicline (Champix®) are not recommended for women who are breast-feeding (Professional Agreement). A free interval between smoking and breastfeeding reduces the concentration of nicotine in milk (NP4). For non-weaned women who are breastfeeding, it is therefore recommended not to smoke just before breast-feeding (Professional Agreement). CONCLUSION The results indicate that breastfeeding is possible in smokers, although less often initiated by them. If the conservation of its benefits for the child is not demonstrated to date, breastfeeding allows the mother to limit smoking.
