Abstract
External urinary catheter devices used in hospitals can offer an alternative to indwelling urinary catheters. Prevalence and patient outcomes are not well understood. This multisite project involved point prevalence of device use in patients with labia on acute care units. All patients on included units with corresponding anatomy were observed for presence of device in addition to review of indication of use and chart audit. Device use was 28.8 %. Immobility was the leading indication, and most patients had severe dysfunction as to mobility. For most patients, level of mobility remained the same from admission to discharge. Many patients were either potentially physically able to mobilize out of bed to urinate or were likely continent. There was variation in suction setting and chart documentation. The project lacked a comparison group and collected limited patient information. Areas for future inquiry include prevalence and impact on mobility, continence, and skin integrity.

Abstract
Patients with familial hypokalemic periodic paralysis (HOKPP) experience episodes of reversible immobility and are at an increased risk of limited sunlight exposure, potentially leading to vitamin D deficiency. However, there is a lack of data on vitamin D levels in this population. We investigated serum vitamin D levels and their associated factors in children with HOKPP. This study included 170 genetically-confirmed children with HOKPP, aged 3-18 years, and 170 age-, sex-, and body mass index (BMI)-matched healthy controls from the Korean Channelopathy Study, a prospective controlled investigation. Anthropometric and clinical characteristics were recorded, and serum levels of calcium, ionized calcium, phosphorus, alkaline phosphatase, 25-hydroxyvitamin D, and intact parathyroid hormone (PTH) were analyzed. Vitamin D deficiency (< 20 ng/mL) was observed in 87.0% of the patients compared to 45.5% of the controls (P < 0.05) during the summer-fall season. During the winter-spring season, 91.7% of the patients and 73.4% of the controls were deficient (P < 0.05). A strong positive correlation was found between onset age of the first paralytic attack and vitamin D levels (r = 0.78, P < 0.01). Conversely, the frequency and duration of paralytic attacks were negatively correlated with vitamin D levels (r = -0.82 and r = -0.65, P < 0.01, respectively). Age, BMI, age at onset, frequency and duration of attacks, and PTH levels were independently associated with vitamin D levels (ß = -0.10, -0.12, 0.19, -0.27, -0.21, and -0.13, P < 0.05, respectively). CONCLUSIONS Vitamin D deficiency was highly prevalent in children with HOKPP, and vitamin D levels correlated with various disease characteristics. We recommend routine screening for vitamin D levels in these patients to address this prevalent deficiency. Considering the high prevalence of vitamin D deficiency observed, further research on other diseases characterized by reversible immobility is warranted. WHAT IS KNOWN • A correlation between immobility and low serum vitamin D levels has been established. However, the vitamin D status of patients with familial hypokalemic periodic paralysis (HOKPP) who experience periods of reversible immobility remains unknown. WHAT IS NEW • Vitamin D deficiency was highly prevalent in children with HOKPP, and vitamin D levels correlated with various disease characteristics.

Abstract
Hippocampal responses to selective 5-HT reuptake inhibitor (SSRI) have long been studied. However, its sub-regional involvements in mediating SSRI's pharmacological effects have not been fully addressed. The current study sought to investigate neurochemical, neurobiological and neurobehavioral changes in response to direct fluoxetine perfusion into the ventral and dorsal sub-regions of the hippocampus in C57BL/6 mice. Following fluoxetine perfusion, time courses of dialysate 5-HT, 5-HT transporter (5-HTT) protein (total, membrane and cytoplasmic fractions), locomotion, and immobility times in the forced swim test (FST) and tail suspension test (TST) were determined. At baseline, 5-HT uptake efficiency assessed by the no-net-flux microdialysis, and 5-HTT protein were measured as well. Results show that fluoxetine dose-dependently increased dialysate 5-HT, lowered membrane 5-HTT protein and increased cytoplasmic fraction without changing the total level, decreased immobility times in both the FST and TST, with greater responses all detected in the ventral sub-region compared to the dorsal sub-region. Fluoxetine didn't affect locomotor activity, ruling out the possibility that fluoxetine's effects on immobility maybe due to alteration in locomotion. Besides, lower 5-HT uptake efficiency and lower membrane 5-HTT protein level were found in the ventral sub-region at baseline. Together, the sub-regional differences at baseline and in responses to fluoxetine added powerful evidence to support the existence of two distinct 5-HT sub-systems in the hippocampus, with greater changes to fluoxetine detected in the ventral sub-system.

Abstract
The aim of this study is to investigate for the first time the uptake and ecotoxicological effects of nanoplastics (NPs) in a marine cnidarian. Ephyrae of the moon jellyfish Aurelia sp. of different ages (0 and 7 days old) were exposed to negatively charged polystyrene NPs for 24 h; then, the uptake was assessed through traditional and novel techniques, namely microscopy and three-dimensional (3D) holotomography. Immobility and behavioral responses (frequency of pulsations) of ephyrae were also investigated to clarify if NP toxicity differed along the first life stages. NP uptake was observed in ephyrae thanks to the 3D technique. Such internalization did not affect survival, but it temporarily impaired the pulsation mode only in 0 day old ephyrae. This may be ascribed to the negative charged NPs, contributing to jellyfish behavioral alteration. These findings promote 3D holotomography as a suitable tool to detect NPs in marine organisms. Moreover, this study recommends the use of cnidarians of different ages to better assess NP ecotoxicological effects in these organisms, key components of the marine food web.

Abstract
Immobility is known to impact health and well-being by reducing social contact, activity participation, and changing time use patterns. These unfortunate effects mostly affect specific demographic segments, including older adults, low income families, people who face disabilities, and those living in conflict zones. Emergency measures taken during the COVID-19 pandemic mandated or strongly recommended limitations to mobility, thereby causing this condition for segments of the public not usually characterized by high levels of immobility. In the context of the pandemic, reduced mobility was the non-pharmaceutical intervention of choice, and the evidence suggests that it helped to keep incidences of the disease from exploding. On the other hand, there is also a need to understand how mobility restrictions may have had incidental impacts, including to well-being, in population groups that have not been studied from this perspective before. In this spirit, the present paper uses the items of the Satisfaction with Life Scale to investigate how aspects of well-being changed during the pandemic, using a sample of 400 college and university students in Dhaka, Bangladesh. Analysis is based on multivariate ordered models and the results suggest that being less mobile, less active, and changes in activity time use due COVID-19 had an impact on the satisfaction with life of students. The detrimental effect was more marked for males and students from low-income households. Additionally, perceptions of residential characteristics and sense of belonging also correlate with satisfaction with life in the period under study.

Abstract
The internal migration literature has identified various factors that deter migration and encourage staying, but has been less concerned with people's own reports about what makes it difficult for them to migrate or makes them want to stay. We explore factors that make it difficult to change the place of residence-from here on denoted as constraints-reported in the Spanish survey on Attitudes and Expectations of Spatial Mobility in the Labour Force (N = 3892). These constraints were uniquely asked from all respondents through an open-ended question, regardless of their migration intentions. We find that many self-reported constraints correspond to factors that have previously been associated with decreased migration propensities. In order of frequency, respondents reported ties to family and friends, ties to their residential environment, financial limitations, and ties to work as constraints to migration. Our results further show that the likelihood of mentioning ties to family and friends as constraints decreased with age, was higher for women than for men and for people who lived close to most of their social network than for those who did not. Mentioning ties to the residential environment as constraints was positively associated with being partnered, and also with living in one's birthplace. People who were unemployed were less likely to mention ties to work and were more likely to report financial limitations as constraints than people who had a permanent contract-whereas being self-employed was positively associated with mentioning ties to the residential environment.

Abstract
This paper describes the Data Domotopia a 2300 + respondent self-administered web-based survey. It includes 100 + multi-purpose items about home-making and stillness in a moving world. We suppose that home-making can reveal coping strategies and resilience practices to make everyday life work - as home is a central location in people's activity-travel patterns. To describe this phenomenon, the concept of Domotopia is introduced, defining how people arrange, use, and experience their homes to cope with the pathologies of accelerated and liquid modernity (Bauman 2005). While the Data Domotopia is based on a mixed-method combining qualitative and quantitative material, this paper focuses mainly on the description of the questionnaire - which is organized into three interrelated layers: the dwelling, the dwellers, and the neighborhood. Each of these layers unfolds in functional, social, emotional and sensory components. The survey covers most of the contemporary issues related to home-making. This includes the domestic space and gender issues; the socio-spatial resources (mobility, action space, core, and wider social network); lifestyles, ideals, and residential aspiration; time pressures, time use, organization and stress; equipment, rules and arrangements; interpersonal relations, cohabitation and negotiation, dominance and power. Intakes on the Data Domotopia is given by two concrete cases about the time-space coverage of the habitual action space, and about inter-personal task allocation. These examples show the potential of the data to study domocentric stillness and resilience to urban pathologies. The data - aggregated to the infra-communal level - is available for research purposes.

Abstract
Escaping from predation saves life, but costs energy and time. The "threat-sensitive predator-avoidance" hypothesis proposes that prey may modulate their antipredator responses, and thus the associated costs, in accordance with the magnitude of predation risk. This process requires that prey accurately assess this risk by decoding available information from various sources. For example, distress calls are uttered by prey when a predator traps them and can serve as public information on predation risk. Such is the case for the weeping lizard whose distress calls trigger immobility in conspecifics. Here, we tested whether this antipredator response of the weeping lizard is modulated by witnessing predation. We exposed lizards to distress calls alone or paired with models of a prey (conspecific), a predator (snake), or a predatory event (a snake subjugating the conspecific). Data show that the sole presence of the predator or prey paired with distress calls seems not to modulate the antipredator responses. Contrarily, witnessing a predatory event associated with calls intensified antipredator responses; lizards reduced their activity for longer and avoided proximity to the stimuli, which may decrease predation risk by reducing the likelihood of being detected by the predator. We conclude that the weeping lizard can use multisensorial public information to assess predation risk and modulate its antipredator responses.

Abstract
Scholarship on the environmental dimensions of migration demonstrates the complex interplay of climatic and non-climatic factors which combine to create a potential for migration. Yet in times of environmental crisis or change, not everyone aspires to or is capable of moving to reduce their vulnerability. When, why, and how populations vulnerable to hazard risks decide not to migrate remains a significant gap in our understanding of the migration-environment relationship. Analysis of data from 38 qualitative interviews shows how Los Angeles County residents-after surviving the 2018 Woolsey Fire-developed aspirations to stay and/or rebuild, depending on the attachments and meanings associated with their communities. This paper also seeks to clarify the concept of capabilities to stay by considering separately the capabilities to return and rebuild from the capabilities to cultivate preparedness. Many who stayed also worked to strengthen community resilience to alleviate concerns of future wildfire risk. Some residents expressed individual commitments to stay and defend homes during future fires, while well-equipped volunteer fire brigades have proliferated in more affluent areas. Community mobilizations pressured local government and fire services to address the perceived institutional failure during previous fire responses and fostered feelings of collective efficacy among residents which increased their confidence to remain in high wildfire risk communities.

Abstract
BACKGROUND Fameyes (a mixture of Clematis mandshurica Rupr. extract (CMRE) and Erigeron annuus (L.) Pers. extract (EAPE)) containing scutellarin and chlorogenic acid as major components has been reported to relieve mental stress in human subjects, which is reflected in improved scores in psychometric tests measuring levels of depression, anxiety, well-being, and mental fitness. The aim of this study was to examine the anti-stress activity of Fameyes and to investigate the mechanisms of the anti-stress activity using in vitro and in vivo models of stresses. RESULTS First, we tested the effect of Fameyes on corticosterone-induced cytotoxicity in SH-SY5Y cells (human neurofibroma cell lines). Corticosterone induced apoptosis and decreased cell viability and mitochondrial membrane potential, but treatment with Fameyes inhibited these cytotoxic effects in a dose-dependent manner. However, CMRE and EAPE (components of Fameyes) did not inhibit the cytotoxic effect of corticosterone individually. Next, we tested the effects of Fameyes on rats that were exposed to different kinds of stresses for four weeks. When the stressed rats were treated with Fameyes, their immobility time in forced swim and tail suspension tests decreased. A reduction was also observed in the serum levels of adrenocorticotropic hormone (ACTH) and corticosterone. Furthermore, upon oral administration of Fameyes, serum serotonin levels increased. These in vitro and in vivo results support the anti-stress effects of Fameyes. CONCLUSIONS In vitro experiments showed anti-stress effects of Fameyes in cell viability, apoptosis, and mitochondrial membrane potential. In addition, in vivo experiments using rats showed anti-stress effects of Fameyes in blood and tissue levels of ACTH, corticosterone, and serotonin, as well as the immobility time in the forced swim and tail suspension tests. However, we did not specifically investigate which ingredient or ingredients showed anti-stress effects, although we reported that Fameyes contained chlorogenic acid and scutellarin major ingredients.

Background and Objectives Current definitions of older adults' mobility do not cover the full range of influencing factors and do not consider nursing home residents. The present study reports expert ratings from a Delphi study regarding factors influencing the mobility of long-term nursing home residents. Research Design and Methods We invited 129 professionals with expertise in a field relevant to research on mobility in older adults such as health care, medicine, or human movement science to participate in a Delphi study comprising 3 rounds of online questionnaires. Up to 40 experts participated in each round. In the first round, we used open-ended questions to solicit possible definitions, contextual factors, and assessment tools. In the second round, the participants used Likert scales (1-10) to rate their suitability. In the final round, we presented a definition based on consensus as well as the top-rated contextual factors and assessment tools from the first 2 rounds for a final rating of agreement. Results The experts showed broad agreement on the final version of the mobility definition, with 8.9 ± 1.4 (mean ± standard deviation) out of 10 points. The experts also showed broad consensus on the selected contextual factors, with 8.4 ± 1.8 points to 8.9 ± 1.2 points (out of 10 points). This was also the case for the top 3 assessment tools selected from results of previous rounds, which showed an agreement of 7 or more points (out of 10 points) by 81.6% to 100% of all experts in the different categories. Discussion and Implications Given that an interdisciplinary group of experts considered various hitherto neglected contextual factors as relevant, the Delphi survey and its results imply the need for an updated interdisciplinary and holistic understanding of mobility in nursing home residents and can provide a basis for putting it into practice.

Abstract
(Im)mobility studies often focus on people on the move, neglecting those who stay, are immobile, or are trapped. The duality of the COVID-19 pandemic and the climate crisis creates a global mental health challenge, impacting the most structurally oppressed, including immobile populations. The construct of immobility is investigated in the context of socio-political variables but lacks examination of the clinical psychological factors that impact immobility. Research is beginning to identify self-reported emotions that immobile populations experience through describing metaphors like feeling trapped. This article identifies links in the literature between Cultural Concepts of Distress drawn from transcultural psychiatry and immobility studies. Feeling trapped is described in mental health research widely. Among (im)mobile people and non-mobility contexts, populations experience various mental health conditions from depression to the cultural syndrome, nervios. The connection of feeling trapped to CCD research lends itself to potential utility in immobility research. The conceptualisation can support broadening and deepening the comprehension of this global mental health challenge - how immobile populations' experience feeling trapped. To broaden the analytical framework of immobility and incorporate CCD, evidence is needed to fill the gaps on the psychological aspects of immobility research.

Abstract
Iron oxide-lignin composites (GLS) were prepared based on the significant role of Fe-OM in the environmental behaviour of heavy metals and lignin binding with iron oxide preferentially in soil. GLS was applied in Cd/Pb immobilization and the stability under acid rain was investigated. The results show that the iron oxide appeared weakly crystalline or amorphous similar to 2-line ferrihydrite after the addition of lignin. Agglomerates of nanoparticles with higher adsorption capacity were observed for GLS. The mobility factor (MF) of Cd/Pb in the soil decreased rapidly after adding GLS. At the 3% dosage, the MF of Cd and Pb in the soil was decreased by 58.94% and 78.15% respectively, which was approximately 5 times that of goethite (GE). The mobile and exchangeable Cd/Pb were converted to organic, amorphous Fe oxide-bound and residue fractions. Under acid rain conditions, MF continues to decline for the GLS group, increasing the organic and amorphous Fe oxide-bound fractions, while for control group (CK) and GE, the trend was the opposite. Lignin could inhibit iron oxide dissolution and stabilize the combination of Cd/Pb and iron oxides in soil. The better stability performance of GLS for Cd/Pb may be related to the higher adsorption capacity and microstructural difference after iron oxide combined with lignin.

Abstract
Stroke patients tend to suffer from immobility, which increases the possibility of post-stroke complications. Urinary tract infections (UTIs) are one of the complications as an independent predictor of poor prognosis of stroke patients. However, the incidence of new UTIs onsets during hospitalization was rare in most datasets with a prevalence of 4%. This imbalanced data distribution sets obstacles to establishing an accurate prediction model. Our study aimed to develop an effective prediction model to identify UTIs risk in immobile stroke patients, and (2) to compare its prediction performance with traditional machine learning models. We tackled this problem by building a Siamese Network leveraging commonly used clinical features to identifying patients with UTIs risk. Model derivation and validation were based on a nationwide dataset including 3982 Chinese patients. Results showed that the Siamese Network performed better than traditional machine learning models in imbalanced datasets (Sensitivity: 0.810; AUC: 0.828).

Abstract
BACKGROUND/AIMS Anti-immobility actions of insulin in diabetic rats that are subjected to the forced swim test (FST) have been reported. In this test, low doses of antidepressants exert actions after long-term treatment, without affecting locomotor activity in healthy rats. Few studies have compared acute and chronic actions of insulin with antidepressants in healthy rats. METHODS We hypothesized that if insulin exerts a true anti-immobility action, then its effects must be comparable to fluoxetine in both a 1-day treatment regimen and a 21-day treatment regimen in healthy, gonadally intact female Wistar rats. RESULTS The results showed that low levels of glycemia were produced by all treatments, including fluoxetine, and glycemia was lower in proestrus-estrus than in diestrus-metestrus. None of the treatments or regimens produced actions on indicators of anxiety in the elevated plus maze. Insulin in the 1-day regimen increased the number of crossings and rearings in the open field test and caused a low cumulative immobility time in the FST. These actions disappeared in the 21-day regimen. Compared with the other treatments, fluoxetine treatment alone or combined with insulin produced a longer latency to the first period of immobility and a shorter immobility time in the chronic regimen in the FST, without affecting locomotor activity, and more pronounced actions were observed in proestrus-estrus (i.e., a true anti-immobility effect). CONCLUSION These results indicate that insulin does not produce a true antidepressant action in healthy rats. The purported antidepressant effects that were observed were instead attributable to an increase in locomotor activity only in the 1-day regimen.

Abstract
Selenium (Se) is regarded as a trace element for humans, but it is toxic in excess. In natural environments, the mobility of Se is dominantly controlled by the Se oxyanions with high solubility such as selenite (Se(IV)). Se(IV) is often associated with the omnipresent ferrihydrite and coexisting organic matter. However, there is little information on the dynamic interactions among Se(IV), fulvic acid, and ferrihydrite. This study investigated the influence of fulvic acid on ferrihydrite-Se(IV) coprecipitates (Fh-Se) transformation for 8 days and the subsequent behavior of Se(IV) at varied pH (5.0, 7.5, and 10.0). Results showed that fulvic acid had different effects on Fh-Se transformation at varied pH values. Fh-Se transformation was promoted by fulvic acid at initial pH 5.0 whereas it was inhibited at initial pH 10.0. Interestingly, at initial pH 7.5, Fh-Se transformation was promoted at a low C/Fe ratio while it was suppressed at a high C/Fe ratio. Besides, fulvic acid induced the generation of more extractable Se(IV) at initial pH 5.0 and more coprecipitated Se(IV) at initial pH 7.5 and blocked the release of Se(IV) at initial pH 10.0. Fulvic acid possibly interacted with Se(IV) via carboxyl complexation and weakened the inhibition of Se(IV) on Fh-Se transformation. Thus, fulvic acid increased the transformation rate of Fh-Se. These findings help to uncover the environmental behavior of Se(IV) and organic matter during ferrihydrite transformation.

Abstract
OBJECTIVES The excitability of lower motor neurons can be explored non-invasively by several neurophysiological techniques, e.g., F-wave and H-reflex studies after a period of immobility and then after subsequent exercise. The aim of this study is to investigate the impact of exercise and high frequency repetitive nerve stimulation (RNS) following changes induced by 75 min of immobility. METHODS We studied 10 healthy subjects following 75 min lower limb immobility, then randomized to RNS or cycling on different days. The neurophysiological studies of M-response, F-wave latency, F/M amplitude ratio and persistence; H-reflex threshold and latency, H/M amplitude ratio, and homosynaptic depression were performed at baseline, after immobility and immediately following the intervention, using stimulation of posterior tibial and peroneal nerves. RESULTS After immobility F-wave latencies were delayed and homosynaptic depression at 2 Hz was increased (p < 0.025). RNS had no effect, but cycling exercise reduced H-reflex latencies (p = 0.025) and decreased homosynaptic depression at 2 Hz. DISCUSSION Our findings suggest that both proprioceptive stimulation and supraspinal pathways modulate intraspinal physiological changes after immobility. These observations suggest that specific exercise protocols may be useful in managing patients recovering from periods of immobility.

Abstract
Die Sarkopenie beschreibt einen generalisierten Verlust von Muskelkraft, -masse und -funktion. Sie geht mit reduzierter Lebensqualität und erhöhter Mortalität einher. Zur Identifizierung gefährdeter Patienten in der Primärversorgung dient der Screeningfragebogen für Sarkopenie (SARC-F), welcher fünf Funktionsbereiche des alltäglichen Lebens erfasst. Im Fall einer relevanten Einschränkung sollte die Messung der Handkraft mithilfe eines Dynamometers und/oder die Beinkraft mithilfe des Chair-Rising-Test erfolgen. Bei pathologischen Ergebnissen sollte der relative Skelettmuskelindex z. B. per Dual-Röntgen-Absorptiometrie bestimmt werden. Unterschreitet dieser den geschlechtsspezifischen Grenzwert, ist die Diagnose einer Sarkopenie zu stellen. Bei normwertiger Muskelmasse liegt eine Präsarkopenie vor. In beiden Fällen sollten die Ursachen abgeklärt und eine Therapie begonnen werden. Eine Verlaufsuntersuchung wird zur Differenzierung zwischen akuter und chronischer Sarkopenie und zur Beurteilung der Krankheitsprogression empfohlen.

Abstract
RATIONALE There is evidence that hypoglycemia, a metabolic stressor, can negatively impact mood and motivation, and can interact with other stressors to potentiate their effects on behavior and physiology. OBJECTIVES/METHODS The current study in male Sprague-Dawley rats explored the interaction between impaired glucose metabolism induced by 0, 200, or 300 mg/kg 2-deoxy-D-glucose (2-DG) and a psychophysical stressor induced by forced swimming stress (FSS; 6 sessions, 10 min/session). The endpoints of interest were blood glucose levels, progressive behavioral immobility, and saccharin preference (2-bottle choice test). Furthermore, it was investigated whether pre-treatment with 0, 10, or 20 mg/kg ketamine could modify the interaction between 2-DG and FSS on these endpoints. RESULTS It was found that 2-DG increased blood glucose levels equally in all experimental groups, accelerated the immobile response to FSS, and suppressed saccharin preference 1 week following termination of stress exposure. As well, pre-treatment with ketamine blocked the effects of combined 2-DG and FSS on immobility and saccharin preference without affecting blood glucose levels and produced an anti-immobility effect that was observed during a drug-free test swim 1 week following administration. CONCLUSIONS Overall, these findings demonstrate that impaired glucose metabolism can potentiate the effects of a psychophysical stressor, and that this interaction can be modulated pharmacologically by ketamine.

Abstract
OBJECTIVE To implement a system for assessing and documenting patient mobility in an inpatient geriatric unit using a quality improvement framework. METHODS Whiteboards incorporating the Johns Hopkins Highest Level of Mobility scale were placed on each door of the unit. Staff were trained to assess and document patient mobility, and documentation compliance was measured. Nurses were surveyed to assess perceived burden of the system. Fall rates were calculated and analyzed for change from baseline. RESULTS Median daily documentation rates reached 79% by the end of the project. Surveys indicated a low perceived burden of the system. Fall rates did not increase when compared to the previous year baseline (p = 0.80) and the analogous time frames during the previous two years (p = 0.84). CONCLUSION A quality improvement framework may be used to improve mobility assessment and documentation in a geriatric unit without increasing patient falls or nursing burden.

Abstract
The current pandemic period has triggered a series of changes in society, at both individual and collective behavioral levels. These changes were perceived as either positive or negative by the impacted bodies, leading to both social change and positive interactions in a tense context. In this paper, the authors will deal with Pandemica Panotpica, subjugation infiltrating all levels of society, and the approach adopted by several countries in trying to find countermeasures to combat the virus' proliferation. Our research scope began at the onset of the pandemic and ended on early January 2021.

Abstract
Our world suffers. Some people suffer more than others. Since the first part of 2020, ours is justly described as a time of uncertainty, threat, and upheaval. In this article, we offer reflections threaded narratively, told from the specificity of our societal contexts in Iran, Canada, and Australia. What might we learn in the present and anticipated future from people living chronically within conditions of uncertainty and immobility and also those experiencing uncertainty and immobility for the first time? We argue that reflexive comparative analysis bridging social and visual analysis, anchored in embodied conditions of such people, offers a way to learn from responses to COVID-19 while also being an exercise in ethical research practice. This reflection builds on and extends from our scholarly collaborations that have been ongoing since 2015. Our title recognizes this specific virus as stealthy. Importantly, our choice of words identifies resident Iranians-whose experiences were the original impetuses for this paper, and whose lives provide its empirical basis (98 is Iran's country code)-as equally steely.

Abstract
A recent paper by Miszczak et al. (2020) examines metal contamination of mires in Poland and Norway. The authors conclude that lead (Pb) records in ombrotrophic peatlands cannot be used to reconstruct the chronological history of anthropogenic activities due to post-depositional mobility of the metal. We contest this general conclusion which stands in contrast with a significant body of literature demonstrating that Pb is largely immobile in the vast majority of ombrotrophic peatlands. Our aim is to reaffirm the crucial contribution that peat records have made to our knowledge of atmospheric Pb contamination. In addition, we reiterate the necessity of following established protocols to produce reliable records of anthropogenic Pb contamination in environmental archives.

Abstract
In the spinal cord, γ-aminobutyric acid (GABA) interneurons play an essential role in antinociception. However, not all actions of GABA favor antinociception at the supraspinal level. We previously reported that gabaculine, which increases endogenous GABA in the synaptic clefts, induces loss of the righting reflex (LORR) that is one indicator of hypnosis, but not immobility in response to noxious stimulus. A slow pain is transmitted to the spinal cord via C fibers and evokes substance P (SP) release from their terminals. However, the antinociceptive effects of gabaculine are still unknown. Our study examined whether the analgesic effects of the opioid morphine or the α2-adrenoceptor agonist dexmedetomidine, whose actions are mediated through facilitation of the descending analgesic pathway, are affected by gabaculine-induced LORR. We also explored the effects of GABA receptor agonists on SP release from cultured dorsal root ganglion (DRG) neurons. All drugs were administered systemically to mice. To assess antinociception, loss of nociceptive response (analgesia) and immobility were evaluated. DRG cells were dissected from rats. Gabaculine produced no analgesia. Either morphine or dexmedetomidine in combination with gabaculine induced immobility; however, the doses of each drug required to induce immobility were much higher than those required to induce analgesia. Capsaicin significantly increased SP release from DRG cells, but a high concentration (1 mM) of the GABA receptor agonist muscimol, propofol, gaboxadol, or baclofen did not inhibit the capsaicin-induced SP release, suggesting that their antinociceptive effects were not through this mechanism. Thus, the gabaculine-induced LORR may inhibit the descending analgesic pathway.

Abstract
Phosphate rock (PR) and ferric salts have been frequently used to immobilize heavy metal(loid)s in soils, but in varied efficiencies referring to different metal(loid) pollutants. This study explored the effective application of plant ash (PA) to the previous formula of phosphate rock (PR) and ferric salts (Fe(NO3)3) (PR + Fe3++PA), compared to only PR, on the bioavailability and immobility of multi-metal(loid)s of selected arsenic (As), lead (Pb) and cadmium (Cd) in soils. Results from NaHCO3- extraction and toxicity characteristic leaching procedure (TCLP) implied the increase of the As mobility in soils by 7.0% and 2.6% using PR only, but the significant reduction of the As mobility by 24.2% and 82.4% jointly using PR + Fe3++PA. Meanwhile, the application of either PR alone or PR + Fe3++PA in soil significantly decreased Pb and Cd extracting in diethylene triamine pentacetate acid (DTPA) and TCLP, particularly, the immobilization effect of PR + Fe3++PA was better than that of PR. The leaching column test further confirmed the high durability of PR + Fe3++PA on the immobilization of As and Pb under the continuous acid exposure, but likely slightly increased the mobility of Cd (the accumulated concentration of Cd, 5.88 μg/L) compared to that (3.16 μg/L) in the untreated column (UN-column), which were both much lower than the level V (100 μg/L) of the Chinese National Quality Standard for Surface Water (GB 3838-2002). Therefore, PR + Fe3++PA exhibited the significant enhancement on the immobilization of As, Pb and Cd under simulated acid rain (SAR) leaching.

Abstract
We use a qualitative, longitudinal study of 25 individuals with mental illness in the UK to better understand the relationships among mental health, power/lessness and im/mobility. Framed by the rise of the new mobilities paradigm and more specifically Cresswell's (2010) politics of mobility, we find that the extent to which the respective mobilities were expressions of internal free will or were undertaken as a result of external compulsion is a key demarcator of mental health. A key contribution is understanding the involuntary nature of (forced) immobility, or what we call entrapment. Entrapment is a punishing phenomenon, which causes distress to those unfortunate to experience it, and which can often be deepened rather than alleviated by those statutory bodies charged with providing care and support. The results speak to the need to recognize that (1) mobility is always relational and contextual, (2) (im)mobility is as much involuntary as voluntary, and that this has crucial implications for (mental) health, and (3) that the experience of individuals suffering from mental illness very much overlaps with what Philo (2017) called 'less-than-human geographies', providing a much-needed rebalance to the over-emphasis on well-being within health geography and (mental) health policy.

Abstract
Stress reactivity and glucocorticoid signaling alterations are reported in mouse models of autism spectrum disorder (ASD). BALB/c mice display decreased locomotor activity in the presence of stimulus mice and spend less time exploring enclosed stimulus mice; this mouse strain has been validated as an ASD model. VU0410120, a glycine type 1 transporter (GlyT1) inhibitor, improved sociability in BALB/c mice, consistent with data that NMDA Receptor (NMDAR) activation regulates sociability, and the endogenous tone of NMDAR-mediated neurotransmission is altered in this strain. Effects of a prosocial dose of VU0410120 on conspecific-provoked immobility, and relationships between conspecific-provoked immobility and corticosterone response were explored. VU0410120-treated BALB/c mice showed reduced immobility in the presence of conspecifics and increased the conspecific-provoked corticosterone response. However, the intensity of conspecific-provoked immobility in VU0410120-treated BALB/c mice did not differ as a function of corticosterone response. Expression profiles of 88 glucocorticoid signaling associated genes within frontal cortex and hippocampus were examined. BALB/c mice resistant to prosocial effects of VU0410120 had increased mRNA expression of Ddit4, a negative regulator of mTOR signaling. Dysregulated mTOR signaling activity is a convergent finding in several monogenic syndromic forms of ASD. Prosocial effects of VU0410120 in the BALB/c strain may be related to regulatory influences of NMDAR-activation on mTOR signaling activity. Because corticosterone response is a marker of social stress, the current data suggest that the stressfulness of a social encounter alone may not be the sole determinant of increased immobility in BALB/c mice; this strain may also display an element of social disinterest.

Abstract
QUESTIONS Does advice from a physiotherapist about the importance of staying physically active during hospitalisation improve activity, mobility, strength, length of stay, and complications in older inpatients? What barriers to physical activity during hospitalisation do older inpatients perceive? DESIGN Randomised controlled trial with concealed allocation, intention-to-treat analysis, and blinded assessment. PARTICIPANTS Sixty-eight people who were aged > 60 years and admitted to a university hospital ward. INTERVENTION In addition to usual hospital care, the experimental group received a booklet with content about the deleterious effects of hospitalisation and the importance of staying active during hospitalisation. The control group received usual hospital care only. OUTCOME MEASURES The amount of physical activity was measured via accelerometry during the hospital admission. Mobility was assessed using the de Morton Mobility Index (DEMMI), and muscle strength was assessed using a handgrip dynamometer. Length of stay and complications were extracted from hospital records. The barriers to staying active during hospitalisation were investigated via a questionnaire. RESULTS Accelerometry showed a mean between-group difference of 974 steps/day (95% CI 28 to 1919) in favour of the experimental group. The intervention also increased moderate-intensity physical activity and reduced sedentary time, although these effects might be trivially small. Experimental group participants were about one-fifth as likely to lose mobility during their hospital admission (two of 33) than control group participants (10 of 35), relative risk 0.21 (95% CI 0.05 to 0.90). Effects of the intervention were unclear regarding muscle strength, length of stay and incidence of complications between the groups. Patients reported that the main barriers to remaining active during hospitalisation were dyspnoea, lack of space, and fear of contracting infection. CONCLUSION In older inpatients, the addition of advice from a physiotherapist about maintaining activity during hospitalisation increases the level of physical activity and prevents loss of mobility.

Abstract
OBJECTIVE To determine whether utilizing beginner, video-guided tai chi and qigong classes as an adjunct to physical therapy to enhance mobilization among hospitalized patients is feasible and acceptable. DESIGN Single-arm feasibility study over a 15½-week period. SETTING Three medical-surgical units at one hospital. INTERVENTIONS Small-group video-guided beginner-level tai chi and qigong classes supervised by physical therapists occurred three times a week. MAIN OUTCOME MEASURES The primary outcome was weekly class attendance. Secondary outcomes included patient and staff satisfaction, collected by surveys and semi-structured interviews. Process measures included class duration. Balancing measures included falls. RESULTS One-hundred and fifty-seven patients were referred for recruitment, 45 gave informed consent, and 38 patients attended at least one class. The number of weekly class attendees increased during the study period. Based on first-class experience, 68% (26/38) of patients reported enjoying the class "quite a bit" or "extremely," 66% (25/38) of patients reported feeling "more mobile" afterward, and 76% (29/38) of patients agreed that the class made them more comfortable going home. Average class duration was 29 minutes. Zero falls occurred during or immediately following class. CONCLUSIONS Video-guided tai chi and qigong classes are feasible and well-received at our hospital. Future studies of the impact on preserving mobility and function or reducing length of stay are of interest.

Abstract
Behavioral analysis in mice provided important contributions in helping understand and treat numerous neurobehavioral and neuropsychiatric disorders. The behavioral performance of animals and humans is widely different among individuals but the neurobehavioral mechanism of the innate difference is seldom investigated. Many neurologic conditions share comorbid symptoms that may have common pathophysiology and therapeutic strategy. The forced swim test (FST) has been commonly used to evaluate the “antidepressant” properties of drugs yet the individual difference analysis of this test was left scantly investigated along with the possible connection among other behavioral domains. This study conducted an FST-screening in outbred CD-1 male mice and segregated them into three groups: high performers (HP) or the active swimmers, middle performers (MP), and low performers (LP) or floaters. After which, a series of behavioral experiments were performed to measure their behavioral responses in the open field, elevated plus maze, Y maze, three-chamber social assay, novel object recognition, delay discounting task, and cliff avoidance reaction. The behavioral tests battery revealed that the three groups displayed seemingly correlated differences in locomotor activity and novel object recognition but not in other behaviors. This study suggests that the HP group in FST has higher locomotor activity and novelty-seeking tendencies compared to the other groups. These results may have important implications in creating behavior database in animal models that could be used for predicting interconnections of various behavioral domains, which eventually helps to understand the neurobiological mechanism controlling the behaviors in individual subjects.

Abstract
The coprecipitation of organic matter (OM) and minerals is a relatively common phenomenon in soil, and it has a significant influence on the surface properties and reactivity of minerals. In turn, the fate of pollutants in soil is greatly affected by the organic-mineral composites. In this study, goethite-fulvic acid (Ge-FA) composites with varying FA mass ratios in the range of 0-15% were synthesized by coprecipitation. The sample properties were studied using XRD, FTIR, SEM-EDS and N2 gas adsorption techniques. The influence of Ge-FA on the mobility of Pb/Cd in soil was investigated. The crystal forms of Ge-FA changed from goethite (FA≤4%) to hematite (FA≥5%), and the FA affected the FeO bond vibrations. These results demonstrated that FA was successfully introduced into the iron oxide. Ge-FA changed from a filamental morphology to an aggregate as the FA ratio increased. The coprecipitation resulted in blockages of iron oxides, thereby decreasing the specific surface area and pore volume. The adsorption amount of Pb(II) on Ge-FA increased as the FA ratio increased, but no significant change was observed for Cd(II). With the application of Ge-FA, the exchangeable concentrations of Pb and Cd in contaminated soil decreased by 42.4%-93.6% and 15.8%-43.7%, respectively. The exchangeable and carbonate bound fractions of Pb and Cd decreased and were transformed into the FeMn bound and residual fractions.

Abstract
INTRODUCTION Pediatric vocal cord paresis (VCP) has a variety of etiologies, including congenital neurologic disease. Arnold-Chiari Malformation (ACM) is one such disease with known VCP association. However, the natural history, need for tracheostomy, and rate of decannulation in this patient population is not well characterized. OBJECTIVE To provide prognostic information on infants with ACM and VCP. METHODS A retrospective chart review was conducted of patients with both ACM and VCP at a single institution. Clinical outcomes and disease progression were determined using flexible laryngoscopy, serial clinical exams, and operative reports from otolaryngology and neurosurgery services. RESULTS Eighteen patients were included in this study, four with ACM Type I and 14 with ACM Type II. These groups were analyzed separately. For ACM I, the average age at diagnosis was 25 months and two (50%) required tracheostomy. Three subjects (75%) achieved VCP resolution, with two doing so after neurosurgical decompression. For ACM II, the average age at diagnosis was eight months and 12 patients (86%) underwent tracheostomy. Four subjects with tracheostomy (33%) achieved decannulation, with three of these demonstrating VCP resolution. In total, six ACM II patients had complete and one had partial VCP resolution, all of whom underwent decompression. Two patients initially had normal endoscopic exams despite stridor and VCP was only noted on serial exams. DISCUSSION This study represents the largest series of pediatric patients with VCP and ACM. The majority needed decompression (80%) and tracheotomy (78%). Tracheostomy decannulation typically occurred only after decompression and resolution of VCP. No children diagnosed at age <1 month were decannulated. Early decompression was associated with successful avoidance of tracheostomy in majority of Chiari I but not Chiari II patients. Serial endoscopies were required to confirm VCP in some patients. This information could potentially aid in management and counseling parents of children with VCP and CM.

Abstract
First mooted in 2011, the concept of Trapped Populations referring to people unable to move from environmentally high-risk areas broadened the study of human responses to environmental change. While a seemingly straightforward concept, the underlying discourses around the reasons for being 'trapped', and the language describing the concept have profound influences on the way in which policy and practice approaches the needs of populations at risk from environmental stresses and shocks. In this article, we apply a Critical Discourse Analysis to the academic literature on the subject to reveal some of the assumptions implicit within discussing 'trapped' populations. The analysis reveals a dominant school of thought that assisted migration, relocation, and resettlement in the face of climate change are potentially effective adaptation strategies along a gradient of migrant agency and governance.

Abstract
Hospitalized patients are at risk of venous thromboembolism (VTE) and prophylaxis is often suboptimal due to difficulty in identifying at-risk patients. Simple and validated risk-assessment models (RAMs) are available to assist clinicians in identifying patients who have a high risk for developing VTE. Despite the well-documented association of immobility with increased risk of thrombosis, immobility is not consistently defined in clinical studies. We conducted a systematic review of published VTE RAMs and used objective criteria to determine how the term immobility is defined in RAMs. We identified 17 RAMs with six being externally validated. The concept of immobility is vaguely described in different RAMs, impacting the validity of these models in clinical practice. The wide variability in defining mobility in RAMs precluded its accurate clinical application, further limiting generalization of published RAMs. Externally validated RAMs with clearly defined qualitative or quantitative terms of immobility are needed to assess VTE risk in real-time at the point-of-care.

Abstract
BACKGROUND Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes. OBJECTIVES The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes. SETTING This study took place at a university hospital in the United States. METHODS The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications. RESULTS There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, P<.001) and greater operative times, length of stay, reoperation rates, and readmissions. Immobile patients had a greater risk of multiple complications, including acute renal failure (OR 6.42, P<.001), pulmonary embolism (OR 2.44, P = .01), cardiac arrest (OR 2.81, P = .05), and septic shock (OR 2.78, P = .02). Regardless of procedure type, immobile patients had a higher incidence of perioperative morbidity compared with ambulatory patients. CONCLUSIONS This study is the first to specifically assess the impact of immobility on 30-day bariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery.

Abstract
A network of interconnected cell groups in the limbic forebrain regulates hypothalamic-pituitary-adrenal (HPA) axis activation and behavioral responses to emotionally stressful experiences, and chronic disruption of these systems chronically is implicated in the pathogenesis of psychiatric illnesses. A significant challenge has been to unravel the circuitry and mechanisms providing for regulation of HPA activity, as these limbic forebrain regions do not provide any direct innervation of HPA effector cell groups in the paraventricular hypothalamus (PVH). Moreover, information regarding how endocrine and behavioral responses are integrated has remained obscure. Here we summarize work from our laboratory showing that anteroventral (av) bed nuclei of the stria terminalis (BST) acts as a point of convergence between the limbic forebrain and PVH, receiving and coordinating upstream influences, and restraining HPA axis output in response to inescapable stressors. Recent studies highlight a more expansive modulatory role for avBST as one that coordinates HPA-inhibitory influences while concurrently suppressing passive behavioral responses via divergent pathways. avBST is uniquely positioned to convey endocrine and behavioral alterations resulting from chronic stress exposure, such as HPA axis hyperactivity and increased passive coping strategies, that may result from synaptic reorganization in upstream limbic cortical regions. We discuss how these studies give new insights into understanding the systems-level organization of stress response circuitry, the neurobiology of coping styles, and BST circuit dysfunction in stress-related psychiatric disorders.

Abstract
BACKGROUND Lost joint range of motion (ROM) is common in chronic osteoarthritis, alters regional weight-bearing across the articular surfaces, and contributes to loss of cartilage and bone alterations. Limited data exist on the regional effects on joints subjected to chronic losses of ROM. OBJECTIVE To characterize the regional replacement by bone as part of articular cartilage degeneration after prolonged immobilization. METHODS Eleven rat knees were rigidly-immobilized in flexion for 32weeks with contralateral and sham-operated (n=6) knees as controls. Sagittal medial tibial epiphysis histological sections assessed the anterior (non-weight-bearing), middle and posterior (both weight-bearing) regions. We quantified the distribution of collagen I, collagen II, cartilage thickness, glycosaminoglycan (GAG) staining, Mankin scoring, and subchondral bone plate cross-sectional area. Using immunohistochemistry (IHC), we visualized blood vessels, osteoblasts, and mesenchymal stem cells (MSCs). RESULTS Immobilized cartilage had increased collagen I content in the anterior tibial region with picrosirius red staining (immobilized=61±20%; contralateral=43±12%, p=0.033; sham=20±10%, p=0.028) and collagen I IHC (immobilized=40±10%; contralateral=11±4%, p=0.003; sham=5±3%, p=0.043). Articular cartilage was thinner anteriorly (18±30μm) in immobilized knees versus contralateral (124±40μm, p<0.001) and sham (125±43μm, p=0.043). GAG staining covered 2±4% of the anterior articular area in immobilized knees versus 28±12% contralaterally (p=0.003) and 26±7% in sham (p=0.043). Mankin scores in immobilized knees were 4.7±1.7 versus 0.2±0.4 and 0±0 for contralateral and sham (p=0.003, p=0.042), respectively. The trabecular bone plate area of anterior and posterior regions showed relative loss of cross-sectional area in immobilized knees compared to controls (immobilized/contralateral area ratios of 0.67 and 0.46 respectively, both p=0.003), while the area in the middle region was preserved. Movat's pentachrome stain and CD31 staining showed chondral vascular ingrowth from subchondral bone. Osteocalcin and CD90 MSC staining were decreased in immobilized knees versus contralateral (p=0.003, p=0.036 respectively). CONCLUSIONS Bony replacement characterizes articular cartilage degeneration of knees immobilized for 32weeks in the anterior, non-weight bearing region of the tibia. Replacement of cartilage by bone may have been mediated by chondral vascularization, suggesting irreversible changes. These findings stress the importance of weight-bearing and joint motion to maintain cartilage structure.

Abstract
Atrazine is an extensively used herbicide, and has become a common environmental contaminant. Effects on dopaminergic neurotransmission in mammals following exposure to atrazine have been previously demonstrated. Here, the effects of atrazine regarding behavioural and dopaminergic neurotransmission parameters were assessed in the fruit fly D. melanogaster, exposed during embryonic and larval development. Embryos (newly fertilized eggs) were exposed to two atrazine concentrations (10μM and 100μM) in the diet until the adult fly emerged. Negative geotaxis assay, as well as exploratory behaviour, immobility time and number of grooming episodes in an open field system were assessed. Tyrosine hydroxylase (TH) activity and gene expression of the dopaminergic system were also evaluated in newly emerged male and female flies. All analyzed parameters in male flies were not significantly affected by atrazine exposure. However female flies exposed to atrazine at 10μM presented an increase in immobility time and a reduction in exploratory activity in the open field test, which was offset by an increase in the number of grooming episodes. Also, female flies exposed to 100μM of atrazine presented an increase in immobility time. Gene expression of DOPA decarboxylase and dopamine (DA) receptors were also increased only in females. The behavioural effects of atrazine exposure observed in female flies were due to a disturbance in the dopaminergic system.

Abstract
In the visual systems of insects, different types of photoreceptors contribute to specialized visual channels that mediate distinct functions and behaviors. Large compound eyes of Periplaneta americana contain photoreceptors of two spectral classes, broadband green-sensitive photoreceptors and narrow-band UV-sensitive photoreceptors. Here, we investigated how visual stimulation by UV and green light affects locomotor, resting, and grooming behaviors in P. americana under conditions when light avoidance is not possible. We show that green but not UV light stimulates locomotor activity, inducing paradoxical positive masking. Duration of resting and grooming decreased with increasing light intensity, consistent with development of behavioral stress in response to visual overstimulation. A reaction of full immobility is described under UV light and at higher intensities of green light, with relative periods of immobility and grooming strongly negatively correlated. Low-intensity UV was more effective than low-intensity green light in suppressing grooming and inducing immobility. Our results suggest that locomotor activity in P. americana is mainly regulated by green-sensitive photoreceptors, and that dim UV light can trigger behavioral immobility, whereas both wavelengths induce stress-like reactions at high intensities. Considering the intrinsic UV sensitivity of green-sensitive photoreceptors, the contrasting behavioral responses indicate antagonistic interactions between UV and green visual channels.

Abstract
Stress can be experienced with or without adverse effects, of which anxiety and depression are two of the most important due to the frequent comorbidity with alcohol abuse in humans. Historically, stress has been considered a cause of drug use, particularly alcohol abuse due to its anxiolytic effects. In the present work we exposed male Wistar rats to two different stress conditions: single housing (social isolation, SI), and chronic mild stress (CMS). We compared both stressed groups to group-housed rats and rats without CMS (GH) to allow the determination of a clear behavioral response profile related to their respective endocrine stress response and alcohol intake pattern. We found that SI and CMS, to a greater extent, induced short-lasting increased sucrose consumption, a transient increase in serum corticosterone level, high latency/immobility, and low burying behavior in the defensive burying behavior (DBB) test, and a transient increase in alcohol intake. Thus, the main conclusion was that stress caused by both SI and CMS induced immobility in the DBB test and, subsequently, induced a transient increased voluntary ethanol intake in Wistar rats with a free-choice home-cage drinking paradigm.

Abstract
UNLABELLED This study assessed the prevalence and types of fractures in spina bifida and examined risk factors for fracture. Fracture prevalence was highest in childhood and reduced in adolescence and young adulthood. The importance of maintaining mobility is highlighted by the increased risk of fracture in those who are non-ambulatory. INTRODUCTION The aims of this study are to study the prevalence and types of fractures according to age group in spina bifida and examine risk factors associated with fracture. METHODS This is a retrospective cohort study of 146 individuals with spina bifida aged 2 years or older who attended the paediatric or adult spina bifida multidisciplinary clinic at a single tertiary hospital. RESULTS Median age at which first fracture occurred was 7 years (interquartile range 4-13 years). Fracture rates in children (ages 2-10), adolescents (ages 11-18) and adults (age > 18) were 10.9/1000 (95 % confidence interval 5.9-18.3), 5.4/1000 (95 % CI 1.5-13.8) and 2.9/1000 (95 % CI 0.6-8.1) patient years respectively. Childhood fractures predominantly involved the distal femur and femoral shaft; these fractures were rarely seen in adulthood. Non-ambulatory status was associated with a 9.8 times higher risk of fracture compared with ambulatory patients (odds ratio 9.8, p = 0.016, 95 % CI 1.5-63.0). Relative risk of re-fracture was 3.1 (95 % CI 1.4-6.8). Urological intervention with intestinal segments was associated with renal calculi (p = 0.037) but neither was associated with fracture. CONCLUSIONS The risk of fracture is lower in adults compared with children with spina bifida. The predominant childhood fracture affects the distal femur, and immobility is the most significant risk factor for fracture. Clinical factors contributing to fracture risk need to be elucidated to enable selection of patients who require investigation and treatment of osteoporosis.

Abstract
Several risk assessment models include infection and immobility among the items to be considered for venous thromboembolism (VTE) prevention. However, information on patients with infection leading to immobility and developing VTE are limited, as well as on the role of specific types of infection. Data were collected from the worldwide RIETE registry, including patients with symptomatic objectively confirmed VTE, and followed-up for at least 3 months. The overall population of RIETE at June 2013 (n = 47,390) was considered. Acute infection leading to immobility was reported in 3.9 % of non-surgical patients. Compared with patients immobilized due to dementia, patients with infection had a shorter duration of immobilization prior to VTE (less than 4 weeks in 94.2 vs. 25.9 % of cases; p < 0.001). During the 3-month follow-up, VTE patients with infection versus those with dementia had a lower rate of fatal bleeding (0.5 vs. 1.1 %; p < 0.05) or fatal PE (1.7 vs. 3.5 %; p < 0.01). Patients with respiratory tract infections had more likely PE as initial VTE presentation than other types of infection (62.3 vs. 37.7 %; p < 0.001). Significantly more patients with pneumonia than those with other respiratory infections had received VTE prophylaxis (50.2 vs. 30.6 %; p < 0.001). Following VTE, patients with sepsis showed a significantly higher risk of fatal bleeding. Based on our real-world data, infection seems to contribute to the pathogenesis of VTE by accelerating the effects of immobility. Its role as VTE risk factor probably deserves further attention and specific assessment in order to optimize VTE prophylaxis and treatment.

Abstract
Neuroligins (NLGNs) regulate synaptic excitability, neuronal signaling and sleep. We hypothesize that alteration of NLGNs is involved in the pathology of depression and tested the hypothesis in a model of depression using Wistar Kyoto (WKy) rat and its control, the Wistar (Wis) rat. We first evaluated behavioral deficits using the forced swim test and then characterized alterations of NLGN1 and NLGN2 with RT-PCR and Western Blotting in the prefrontal cortex, motor frontal cortex and hippocampus. Compared with controls of Wis rats, (1) the WKy rats had significantly shorter swim time and longer immobile time; (2) NLGN1 mRNA levels was higher in the motor frontal cortex and hippocampus in the WKy model; (3) NLGN1 protein was significantly higher in the motor frontal cortex, the prefrontal cortex and the hippocampus in the WKy model; (4) NLGN2 mRNA was significantly higher in the motor frontal cortex but significantly lower in the hippocampus in the WKy model. We concluded that NLGN1 gene and protein expression is higher in the motor frontal cortex, hippocampus and in the prefrontal cortex in the WKy rats suggesting that alterations of NLGN1 is involved in the pathology of depression but need to be further evaluated in human.

Abstract
Rodents show grooming, a typical self-care behavior, under stress and non-stress conditions. Previous studies revealed that grooming under stress conditions such as the open-field test (OFT) or the elevated plus-maze test (EPM) is associated with anxiety, but the roles of grooming under non-stress conditions are not well understood. Here, we examined spray-induced grooming as a model of grooming under a non-stress condition to investigate the relationship between this grooming and depression-like behavior in the forced swim test (FST) and tail suspension test, and we compared spray-induced grooming with OFT- and EPM-induced grooming. The main finding was that the duration of spray-induced grooming, but not that of OFT/EPM-induced grooming, was negatively correlated with the duration of immobility in the FST, an index of depression-like behavior. The results suggest that spray-induced grooming is functionally different from the grooming in the OFT and EPM and is related to reduction of depressive behavior.

Abstract
Brain-derived neurotrophic factor (BDNF) binds to Tropomyosin-receptor-kinase B (TrkB) receptors that regulate synaptic strength and plasticity in the mammalian nervous system. 7,8-Dihydroxyflavone (DHF) is a recently identified small molecule Trk B agonist that has been reported to ameliorate depression, attenuate the fear response, improve memory consolidation, and exert neuroprotective effects. Poor and disturbed sleep remains a symptom of major depressive disorder and most current antidepressants affect sleep. Therefore, we conducted sleep/wake recordings and concomitant measurement of brain orexins, endogenous peptides that suppress sleep, in mice for this study. Baseline polysomnograph recording was performed for 24 h followed by treatment with either 5 mg/kg of DHF or vehicle at the beginning of the dark phase. Animals were sacrificed the following day, one hour after the final treatment with DHF. Orexin A and B were quantified using ELISA and radioimmunoassay, respectively. Total sleep was significantly decreased in the DHF group, 4 h after drug administration in the dark phase, when compared with vehicle-treated animals. This difference was due to a significant decrease of non-rapid eye movement sleep, but not rapid eye movement sleep. DHF increased power of alpha and sigma bands but suppressed power of gamma band during sleep in dark phase. Interestingly, hypothalamic levels of orexin A were also significantly decreased in the DHF group (97 pg/mg) when compared with the vehicle-treated group (132 pg/mg). However, no significant differences of orexin B were observed between groups. Additionally, no change was found in immobility tests.

Abstract
The aim of this study was to investigate nursing staff induced repositionings and the patients' spontaneous movements during the day and night among older immobile patients in nursing care. Furthermore, the aim was to identify factors associated with the nursing staff induced repositionings and the patients' spontaneous movement frequency. An observational cross-sectional design was used. Spontaneous movements among patients (n = 52) were registered continuously using the MovinSense monitoring system. The nursing staff documented each time they repositioned the patient. Patients spontaneous movements were compared with nursing staff induced repositionings. There were large variations in the patients' spontaneous repositioning frequency during both days and nights, which shows that, although immobilised, some patients frequently reposition themselves. Analgesics were positively related to the movement frequency and psycholeptics were negatively related. The nursing staff more often repositioned the patients who were assessed as high risk than those assessed as low risk, but the patients' spontaneous movement frequency was not correlated to the risk score. This may be important when planning repositioning schedules. A monitoring system may be useful in decision making with regard to planning repositioning and positions used in the prevention of pressure ulcers among elderly immobile patients.

Abstract
PURPOSE While actigraphy has gained popularity in pediatric sleep research, questions remain about the validity of actigraphy as an estimate of sleep-wake patterns. In particular, there is little consistency in the field in terms of scoring rules used to determine sleep onset latency. The purpose of this study was to evaluate different criteria of immobility as a measure of sleep onset latency in children and adolescents. METHODS Ninety-five youth (ages 3-17 years, 46 % male) wore both the Ambulatory Monitoring Inc. Motionlogger Sleep Watch (AMI) and the Philips Respironics Mini-Mitter Actiwatch-2 (PRMM) during overnight polysomnography in a pediatric sleep lab. We examined different sleep onset latency scoring rules (3, 5, 10, 15, and 20 min of immobility) using different algorithms (Sadeh and Cole-Kripke) and sensitivity settings (low, medium, high) for the devices. Comparisons were also made across age groups (preschoolers, school-aged, adolescents) and sleep disordered breathing status (no obstructive sleep apnea [OSA], mild OSA, clinically significant OSA). RESULTS For the AMI device, shorter scoring rules performed best for children and longer scoring rules were better for adolescents, with shorter scoring rules best across sleep disordered breathing groups. For the PRMM device, medium to longer scoring rules performed best across age and sleep disordered breathing groups. CONCLUSIONS Researchers are encouraged to determine the scoring rule that best fits their population of interest. Future studies are needed with larger samples of children and adolescents to further validate actigraphic immobility as a proxy for sleep onset latency.

Abstract
Decreased orexin level has been well demonstrated in patients suffering from narcolepsy, depression accompanied with suicide attempt; obstructive sleep apnea and comorbidity were also demonstrated in these diseases. As C57BL/6J (B6) mice are more "depressed" and have lower brain orexins than A/J mice, B6 mice having chromosome 1 replacement (B6A1 mice) might have restored orexin levels and less depressive behavior. We studied the behavior of 4-6 month old B6, A/J and B6A1 mice with forced swim, tail suspension, and locomotor activity tests. The animals were then sacrificed and hypothalamus and medullas dissected from brain tissue. Orexins-A and -B were determined by radioimmunoassay. Compared with A/J mice, B6 mice displayed several signs of depression, including increased immobility, increased locomotors activity, and decreased orexin A and -B levels in both the hypothalamus and medulla. Compared to B6 mice, B6A1 mice exhibited significantly higher levels of orexins-A and -B in both brain regions. B6A1 mice also exhibited antidepressive features in most of measured variables, including decreased locomotor activity, decreased immobility and increased swim in tail suspension test; compared with B6 mice, however. B6A1 mice also reversed immobility in the early phase of the swim test. In summary, B6 mice exhibited depressive attributes compared with A/J mice, including increased locomotor activity, greater immobility, and decreased brain orexins, these were largely reversed in B6A1 mice. We conclude that orexin levels modulate these B6 behaviors, likely due to expression of A/J alleles on Chromosome 1.
