Abstract
Background The heartbeat evoked potential (HEP) is a brain response time-locked to the heartbeat and a potential marker of interoceptive processing. The insula and dorsal anterior cingulate cortex (dACC) are brain regions that may be involved in generating the HEP. Low-intensity focused ultrasound (LIFU) is a non-invasive neuromodulation technique that can selectively target sub-regions of the insula and dACC to better understand their contributions to the HEP. Objective Proof-of-concept study to determine whether LIFU modulation of the anterior insula (AI), posterior insula (PI), and dACC influences the HEP. Methods In a within-subject, repeated-measures design, healthy human participants (n=16) received 10 minutes of stereotaxically targeted LIFU to the AI, PI, dACC or Sham at rest during continuous electroencephalography (EEG) and electrocardiography (ECG) recording on separate days. Primary outcome was change in HEP amplitudes. Relationships between LIFU pressure and HEP changes were examined using linear mixed modelling. Peripheral indices of visceromotor output including heart rate and heart rate variability (HRV) were explored between conditions. Results Relative to sham, LIFU to the PI, but not AI or dACC, decreased HEP amplitudes; this was partially explained by increased LIFU pressure. LIFU did not affect time or frequency dependent measures of HRV. Conclusions These results demonstrate the ability to modulate HEP amplitudes via non-invasive targeting of key interoceptive brain regions. Our findings have implications for the causal role of these areas in bottom-up heart-brain communication that could guide future work investigating the HEP as a marker of interoceptive processing in healthy and clinical populations.

Abstract
Hyperarousal symptoms in generalized anxiety disorder (GAD) are often incongruent with the observed physiological state, suggesting that abnormal processing of interoceptive signals is a characteristic feature of the disorder. To examine the neural mechanisms underlying interoceptive dysfunction in GAD, we evaluated whether adrenergic modulation of cardiovascular signaling differentially affects the heartbeat-evoked potential (HEP), an electrophysiological marker of cardiac interoception, during concurrent electroencephalogram and functional magnetic resonance imaging (EEG-fMRI) scanning. Intravenous infusions of the peripheral adrenergic agonist isoproterenol (0.5 and 2.0 micrograms, μg) were administered in a randomized, double-blinded and placebo-controlled fashion to dynamically perturb the cardiovascular system while recording the associated EEG-fMRI responses. During the 0.5 μg isoproterenol infusion, the GAD group (n = 24) exhibited significantly larger changes in HEP amplitude in an opposite direction than the healthy comparison (HC) group (n = 24). In addition, the GAD group showed significantly larger absolute HEP amplitudes than the HC group during saline infusions, when cardiovascular tone did not increase. No significant group differences in HEP amplitude were identified during the 2.0 μg isoproterenol infusion. Using analyzable blood oxygenation level-dependent fMRI data from participants with concurrent EEG-fMRI data (21 GAD and 21 HC), we found that the aforementioned HEP effects were uncorrelated with fMRI signals in the insula, ventromedial prefrontal cortex, dorsal anterior cingulate cortex, amygdala, and somatosensory cortex, brain regions implicated in cardiac signal processing in prior fMRI studies. These findings provide additional evidence of dysfunctional cardiac interoception in GAD and identify neural processes at the electrophysiological level that may be independent from blood oxygen level-dependent responses during peripheral adrenergic stimulation.

Abstract
Interoception-the perception of internal bodily signals-has emerged as an area of interest due to its implications in emotion and the prevalence of dysfunctional interoceptive processes across psychopathological conditions. Despite the importance of interoception in cognitive neuroscience and psychiatry, its experimental manipulation remains technically challenging. This is due to the invasive nature of existing methods, the limitation of self-report and unimodal measures of interoception, and the absence of standardized approaches across disparate fields. This article integrates diverse research efforts from psychology, physiology, psychiatry, and engineering to address this oversight. Following a general introduction to the neurophysiology of interoception as hierarchical predictive processing, we review the existing paradigms for manipulating interoception (e.g., interoceptive modulation), their underlying mechanisms (e.g., interoceptive conditioning), and clinical applications (e.g., interoceptive exposure). We suggest a classification for interoceptive technologies and discuss their potential for diagnosing and treating mental health disorders. Despite promising results, considerable work is still needed to develop standardized, validated measures of interoceptive function across domains and before these technologies can translate safely and effectively to clinical settings.

Abstract
INTRODUCTION Injuries induced by falls represent the main cause of failure in the French Navy Special Forces selection course. In the present study, we made the assumption that probing the posture might contribute to predicting the risk of fall-related injury at the individual level. METHODS Before the start of the selection course, the postural signals of 99 male soldiers were recorded using static posturography while they were instructed to maintain balance with their eyes closed. The event to be predicted was a fall-related injury during the selection course that resulted in the definitive termination of participation. Following a machine learning methodology, we designed an artificial neural network model to predict the risk of fall-related injury from the descriptors of postural signal. RESULTS The neural network model successfully predicted with 69.9% accuracy (95% CI 69.3-70.5) the occurrence of a fall-related injury event during the selection course from the selected descriptors of the posture. The area under the curve value was 0.731 (95% CI 0.725-0.738), the sensitivity was 56.8% (95% CI 55.2-58.4) and the specificity was 77.7% (95% CI 76.8-0.78.6). CONCLUSION If confirmed with a larger sample, these findings suggest that probing the posture using static posturography and machine learning-based analysis might contribute to inform risk assessment of fall-related injury during military training, and could ultimately lead to the development of novel programmes for personalised injury prevention in military population.

Abstract
INTRODUCTION The Military Physical and Sports Training program was developed by the French Army in order to train, optimize, and maintain individual readiness. Although the health benefits of sport practice do not need to be demonstrated, such activities can cause acute musculoskeletal injuries that need to be addressed. The prevalence of lower limb injury is rather high in the French military population and, in particular, ranges from 15 to 45% during Special Forces selection courses. Thus, this project aims to investigate the efficiency of a body-centered program designed to enhance body awareness. The program seeks to train the mind to actively pay attention to body information, while the latter is viewed as a protective factor against fall injuries. We assume: (i) that postural control can be improved by enhancing the level of body awareness; and (ii) that greater postural awareness could be beneficial in reducing the risk of fall injuries. The body-centered prevention program is based on the Optimization of the Resources of the Armed Forces (ORAF) intervention, which focuses on mental preparation and recovery, and has been deployed in the French Army for many years. METHOD AND ANALYSES The study focuses on five French Special Forces selection courses (400 soldiers/ participants). It is divided into two stages (year 1, year 2). The first year is dedicated to data collection from the control group (200 participants), while in the second year the ORAF intervention will be deployed. In both year, participants will be subjected to the same enrollment schedule (Fig 3). The main objective is to evaluate the effectiveness of the ORAF intervention in reducing the rate of fall injuries during military selection, based on a multidisciplinary method that captures demographic, biological, biometric, clinical, and para-clinical measures.

Abstract
Enhanced body awareness has been suggested as one of the cognitive mechanisms that characterize mindfulness. Yet neuroscience literature still lacks strong empirical evidence to support this claim. Body awareness contributes to postural control during quiet standing; in particular, it may be argued that body awareness is more strongly engaged when standing quietly with eyes closed, because only body cues are available, than with eyes open. Under these theoretical assumptions, we recorded the postural signals of 156 healthy participants during quiet standing in Eyes closed (EC) and Eyes open (EO) conditions. In addition, each participant completed the Freiburg Mindfulness Inventory, and his/her mindfulness score was computed. Following a well-established machine learning methodology, we designed two numerical models per condition: one regression model intended to estimate the mindfulness score of each participant from his/her postural signals, and one classifier intended to assign each participant to one of the classes “Mindful” or “Non-mindful.” We show that the two models designed from EC data are much more successful in their regression and classification tasks than the two models designed from EO data. We argue that these findings provide the first physiological evidence that contributes to support the enhanced body awareness hypothesis in mindfulness.

Abstract
Body awareness refers to the individual ability to process signals originating from within the body, which provide a mapping of the body’s internal landscape (interoception) and its relation with space and movement (proprioception). The present study aims to evaluate psychometric properties and validate in French two self-report measures of body awareness: the Postural Awareness Scale (PAS), and the last version of the Multidimensional Assessment of Interoceptive Awareness questionnaire (version 2, MAIA-2). We collected data in a non-clinical, adult sample (N = 308; 61% women, mean age 35 ± 12 years) using online survey, and a subset of the original sample (n = 122; 62% women, mean age 44 ± 11 years) also completed the retest control. Factor analyses and reliability analyses were conducted. Construct validity of the PAS and the MAIA-2 were examined by testing their association with each other, and with self-report measures of personality (Big Five Inventory), alexithymia (Toronto Alexithymia Scale) and dispositional trait mindfulness (Freiburg Mindfulness Inventory). Factor analyses of the PAS supported the same two-factor structure as previously published versions (in other languages). For the MAIA-2, factor analyses suggested that a six-factor structure, excluding Not-Worrying and Not-Distracting factors, could successfully account for a common general factor of self-reported interoception. We found satisfactory internal consistency, construct validity, and reliability over time for both the PAS and the MAIA-2. Altogether, our findings suggest that the French version of the PAS and the MAIA-2 are reliable self-report tools to assess both components of body awareness (proprioception and interoception dimension, respectively).

Abstract
While the coronavirus disease 2019 (COVID-19) pandemic placed a heavy burden on healthcare systems worldwide, it also induced urgent mobilisation of research teams to develop treatments preventing or curing the disease and its consequences. It has, therefore, challenged critical care research to rapidly focus on specific fields while forcing critical care physicians to make difficult ethical decisions. This narrative review aims to summarise critical care research -from organisation to research fields- in this pandemic setting and to highlight opportunities to improve research efficiency in the future, based on what is learned from COVID-19. This pressure on research revealed, i.e., i/ the need to harmonise regulatory processes between countries, allowing simplified organisation of international research networks to improve their efficiency in answering large-scale questions; ii/ the importance of developing translational research from which therapeutic innovations can emerge; iii/ the need for improved triage and predictive scores to rationalise admission to the intensive care unit. In this context, key areas for future critical care research and better pandemic preparedness are artificial intelligence applied to healthcare, characterisation of long-term symptoms, and ethical considerations. Such collaborative research efforts should involve groups from both high and low-to-middle income countries to propose worldwide solutions. As a conclusion, stress tests on healthcare organisations should be viewed as opportunities to design new research frameworks and strategies. Worldwide availability of research networks ready to operate is essential to be prepared for next pandemics. Importantly, researchers and physicians should prioritise realistic and ethical goals for both clinical care and research.

Abstract
OBJECTIVE Post-traumatic stress disorder (PTSD) is a chronic, disabling condition. Our main objective is to investigate the association between trait mindfulness and PTSD over a period of 54 months. The secondary objective is to provide an exhaustive description of PTSD trajectories after the Bataclan attack. METHODS We designed a prospective cohort study of 133 subjects present in the Bataclan concert hall during the November 2015 terrorist attack in Paris, France. Data were recorded 6, 18, 30, and 54 months after the attack. The primary endpoint was evaluated using the PTSD Check List Scale. Trait mindfulness was measured by the 14-item Freiburg Mindfulness Inventory. RESULTS FMI scores were consistently, significantly, and negatively associated with PCL-5 scores. Adjusted odds ratios were at 0.81 (6 months), 0.88 (18 months) 0.82 (30 months), and 0.81 (54 months). PTSD prevalence 6 months after the event was 77%; it remained at 41% after 54 months. PTSD status of subjects is fluctuating. Latent class analysis divided the cohort into 3 groups: 21% of subject who remained below PTSD threshold throughout, 30% who remained above throughout, and 49% who steadily reduced their PTSD scores over time. CONCLUSION In our cohort, mindfulness is negatively associated with PTSD. Mindfulness programs are designed to improve global resilience and treat anxiety and mood disorders. Further research is needed to investigate if improving trait mindfulness is possible and beneficial for patients suffering from PTSD.

Abstract
The enhancement of body awareness is proposed as one of the cognitive mechanisms that characterize mindfulness. To date, this hypothesis is supported by self-report and behavioral measures but still lacks physiological evidence. The current study investigated relation between trait mindfulness (i.e., individual differences in the ability to be mindful in daily life) and body awareness in combining a self-report measure (Multidimensional Assessment of Interoceptive Awareness [MAIA] questionnaire) with analysis of the heartbeat evoked potential (HEP), which is an event-related potential reflecting the cortical processing of the heartbeat. The HEP data were collected from 17 healthy participants under five minutes of resting-state condition. In addition, each participant completed the Freiburg Mindfulness Inventory and the MAIA questionnaire. Taking account of the important variability of HEP effects, analyses were replicated with the same participants three times (in three distinct sessions). First, group-level analyses showed that HEP amplitude and trait mindfulness do not correlate. Secondly, we observed that HEP amplitude could positively correlate with self-reported body awareness; however, this association was unreliable over time. Interestingly, we found that HEP measure shows very poor reliability over time at the individual level, potentially explaining the lack of reliable association between HEP and psychological traits. Lastly, a reliable positive correlation was found between self-reported trait mindfulness and body awareness. Taken together, these findings provide preliminary evidence that the HEP might not support the increased subjective body awareness in trait mindfulness, thus suggesting that perhaps objective and subjective measures of body awareness could be independent.

Abstract
The piezoelectric cage-floor sensors have been used to successfully dissect sleep patterns in mice based on signal features related to respiration and body movements. We studied performance of the piezoelectric system to quantify the sleep-wake pattern in the rat over 7 days of recording compared with a visual electroencephalogram/electromyogram scoring, and under two light/dark (LD12:12 and LD16:8) photoperiods leading to change in the 24-hr sleep characteristics (N = 7 per group). The total sleep time (%/24 hr) over the 7 days recording and hourly sleep time over the last 24-hr recording were not statistically different between methods under the two photoperiods. Both methods detected higher total sleep time with the LD16:8 photoperiod compared with LD12:12 (p < .05), and correlated significantly (p < .001) at light and dark periods during each photoperiod. The accuracies for discrimination of sleep-wake patterns between methods were 81.9% and 84.9% for LD12:12 and LD16:8, respectively. In addition, spectral analysis of the respiratory signal given by piezo during all 10-s periods of the corresponding non-rapid eye movement and rapid eye movement sleep periods recorded by electroencephalogram/electromyogram resulted in selection of 36 features that could be inserted in an automated non-rapid eye movement sleep and rapid eye movement sleep classification, with 90% accuracy with the electroencephalogram/electromyogram visual scoring. The piezo system proved to be a reliable non-invasive alternative to electroencephalogram recording to study total sleep time in rat, with feasibility to discriminate between non-rapid eye movement and rapid eye movement sleep stages. This will be interesting in pharmacological or bio-behavioural studies evaluating sleep patterns or the restorative functions of sleep in the body and the brain.

Abstract
INTRODUCTION Over the past two decades, overseas deployments of the French Army have been characterized by the exposure of its service personnel to sustained, high levels of combat stress. There is a need to assess their mental health throughout the deployment cycle, identify risk factors associated with stress-related disorders, and characterize the factors that promote long-term well-being. METHODS We conducted two pilot studies within four units of the French Army: a conventional combat unit, a counterterrorist unit, a combat service support unit, and a medical support unit. Study 1 (n = 65) analyzed the psychological functioning of service personnel with respect to their personality and stress management characteristics. Study 2 (n = 40) analyzed the impact of overseas deployment on stress-related psychological outcomes. RESULTS Overall, results from study 1 showed that service personnel have a protective psychological functioning, which is particularly developed in the counterterrorist unit. In study 2, although no stress-related disorder symptoms were observed with the psychometric tools used, a certain degree of psychological dysfunction (social dysfunction and lower positive affect) was detected post-deployment. CONCLUSIONS These two complementary studies are key elements in developing a better understanding of unmet, medico-military needs that lie on the pathway that links exposure to stressors to impaired health. Certain personnel enrolled in the French Army (notably, the counterterrorist unit) were found to have a high level of protective psychological functioning, largely due to the training they receive. Nevertheless, overall, overseas deployment was associated with poorer psychological functioning and the emergence of social dysfunction, especially in units responsible for the care of service personnel (medical support and combat service support units).

Abstract
Neuroimaging, behavioral, and self-report evidence suggests that there are four main cognitive mechanisms that support mindfulness: (a) self-regulation of attention, (b) improved body awareness, (c) improved emotion regulation, and (d) change in perspective on the self. In this article, we discuss these mechanisms on the basis of the event-related potential (ERP). We reviewed the ERP literature related to mindfulness and examined a data set of 29 articles. Our findings show that the neural features of mindfulness are consistently associated with the self-regulation of attention and, in most cases, reduced reactivity to emotional stimuli and improved cognitive control. On the other hand, there appear to be no studies of body awareness. We link these electrophysiological findings to models of consciousness and introduce a unified, mechanistic mindfulness model. The main idea in this refined model is that mindfulness decreases the threshold of conscious access. We end with several working hypotheses that could direct future mindfulness research and clarify our results.

Abstract
Bacteremia with streptococcus group G is a rare infection, particularly in the post-partum, but of which the incidence has been increasing since the end of the 20th century. The objective of our work is to report the clinical and the bacteriologic aspects, as well as the therapeutic modalities of an exceptional case of bacteremia with streptococcus group G, after a normal vaginal delivery, in a 26-year-old woman. Streptococcus group G being a part of the normal flora of the female genital tract, the endogenous contamination probably took place by passage in the blood circulation during the episiotomy.

Abstract
Human pancreatic polypeptide (HPP) increases after insulin-induced hypoglycemia. To determine whether adrenergic mechanisms contribute to this increase in normal man, six subjects were studied on two occasions: once after insulin alone and once after insulin plus simultaneous alpha (phentolamine)- and beta (propranolol)-adrenergic blockade. Despite comparable hypoglycemia (51 +/- 4 vs. 49 +/- 4 mg/dl), the increase in HPP did not differ in the presence or absence of adrenergic blockade (721 +/- 215 vs. 736 +/- 193 pg/ml, respectively). These findings suggest that HPP secretion during hypoglycemia is not dependent on adrenergic mechanisms.

Abstract
The present studies were undertaken to assess the mechanism by which insulin increases glucose uptake in man. Because glucose uptake in most mammalian tissues occurs predominantly by a facilitated transport system that follows Michaelis-Menten kinetics, glucose uptake was measured isotopically in normal volunteers over the physiologic range of plasma glucose and insulin concentrations and was subjected to Lineweaver-Burk and Eadie-Hofstee analysis. With both methods, increases in plasma insulin from 18 microunits/ml to 80 and 150 microunits/ml were found to increase the maximum velocity (Vmax) for glucose uptake nearly three- and fivefold, respectively, (P less than 0.025 and P less than 0.001) without significantly altering the Michaelis constant (Km). Because an increase in the affinity or molecular activity of transport sites or provision of additional transport sites that differed from those present basally should have altered the Km, whereas a mere increase in the number of transport sites would have only increased the Vmax, our results indicate that in man, insulin may increase glucose uptake merely by providing additional transport sites.

Abstract
Nelson's syndrome occurs in 10 to 35 percent of patients treated for Cushing's disease by bilateral adrenalectomy and features an ACTH-producing pituitary tumor and hyperpigmentation. Cortisol-producing testicular tumors activated by markedly elevated ACTH levels have been described in male patients with Nelson's syndrome. We now describe a female patient with Nelson's syndrome who presented with virilization. Abdominal exploration revealed adrenal rest tumors in the paraovarian tissues and adrenal beds. Iodocholesterol scanning gave negative results. This case illustrates the need for follow-up study of patients with bilateral adrenalectomy for Cushing's disease and describes some of the unusual features these patients may present.

Abstract
Restoration of near-normal glucose metabolism with the insulin pump reduces retinal fluorescein leakage and microalbuminuria in diabetes. However, it is not known whether these functional changes reflect a true reversal of diabetic retinopathy or nephropathy. To evaluate this question, we studied the effect of 1-2 yr of insulin pump treatment on clinical endpoints in 17 type I diabetic patients. In each patient, plasma glucose and total glycosylated hemoglobin levels fell to normal or near-normal levels. The total daily dose of insulin given during the first month of pump treatment (52 +/- 5 U/day) was comparable to that given during conventional treatment (44 +/- 3 U/day) and varied little over the 1-2 yr period of observation. Ten eyes without retinopathy at the start of the study remained without retinopathy after 15-23 mo of pump treatment. One of eleven eyes with background retinopathy developed proliferative retinopathy and 3 of 13 eyes with proliferative retinopathy progressed during pump treatment. Similarly, no improvement in renal function was observed in the six patients with diabetic nephropathy on entry to the study. In the first month of pump treatment, proteinuria consistently fell to values 30% below prepump levels (P less than 0.005). However, the diminution in proteinuria was not sustained and all remain proteinuric after 13-18 mo of pump therapy. Serum creatinine rose slightly and creatinine clearance did not significantly change. These data suggest that insulin pump treatment does not reverse established diabetic microvascular complications, despite a sustained improvement in metabolic control for up to 2 yr.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
UNLABELLED Infusion of glucagon causes only a transient increase in glucose production in normal and diabetic man. To assess the effect of intermittent endogenous hyperglucagonemia that might more closely reflect physiologic conditions, arginine (10 g over 30 min) was infused four times to 8 normal subjects and 13 insulin-dependent diabetic subjects (4 of whom were infused concomitantly with somatostatin to examine effects of arginine during prevention of hyperglucagonemia). Each arginine infusion was separated by 60 min. Diabetic subjects were infused throughout the experiments with insulin at rates (0.07-0.48 mU/kg per min) that had normalized base-line plasma glucose and rates of glucose appearance (Ra) and disappearance (Rd). Basal plasma glucagon and arginine-induced hyperglucagonemia were similar in both groups; basal serum insulin in the diabetics (16+/-1 muU/ml, P < 0.05) exceeded those of the normal subjects (10+/-1 muU/ml, P < 0.05) but did not increase with arginine. Serum insulin in normal subjects increased 15-20 muU/ml with each arginine infusion. In both groups each arginine infusion increased plasma glucose and Ra. Increments of Ra in the diabetics exceeded those of normal subjects, (P < 0.02); Rd was similar in both groups. In normal subjects, plasma glucose returned to basal levels after each arginine infusion, whereas in the diabetics hyperglycemia persisted reaching 151+/-15 mg/dl after the last arginine infusion. When glucagon responses were prevented by somatostatin, arginine infusions did not alter plasma glucose or Ra. CONCLUSIONS Infusion of arginine acutely increases plasma glucose and glucose production in man solely by stimulating glucagon secretion; physiologic increments in plasma glucagon (100-150 pg/ml) can result in sustained hyperglycemia when pancreatic beta cell function is limited.
