Abstract
BACKGROUND Autonomic dysfunction is prevalent in Parkinson's disease (PD) and can worsen quality of life. We examined: (a) whether specific autonomic symptoms were more strongly associated with anxiety or depression in PD and (b) whether overall autonomic dysfunction predicted mood trajectories over a 5-year period. METHODS Newly diagnosed individuals with PD (N = 414) from the Parkinson's Progression Markers Initiative completed self-report measures of depression, anxiety, and autonomic symptoms annually. Cross-sectional linear regressions examined relationships between specific autonomic subdomains (gastrointestinal, cardiovascular, thermoregulatory, etc.) and mood. Multilevel modeling examined longitudinal relationships with total autonomic load. RESULTS Gastrointestinal symptoms were associated with both higher anxiety (b = 1.04, 95% CI [.55, 1.53], P < .001) and depression (b = .24, 95% CI [.11, .37], P = .012), as were thermoregulatory symptoms (anxiety: b = 1.06, 95% CI [.46, 1.65], P = .004; depression: b = .25, 95% CI [.09, .42], P = .013), while cardiovascular (b = .36, 95% CI [.10, .62], P = .012) and urinary symptoms (b = .10, 95% CI [.01, .20], P = .037) were associated only with depression. Longitudinally, higher total autonomic load was associated with increases in both depression (b = .01, 95% CI [.00, .02], P = .015) and anxiety (b = .04, 95% CI [.01, .06], P < .001) over time, as well as occasion-to-occasion fluctuations (depression: b = .08, 95% CI [.05, .10], P < .001; anxiety: b = .24, 95% CI [.15, .32], P < .001). CONCLUSION Findings suggest autonomic dysfunction, particularly gastrointestinal and thermoregulatory symptoms, may be an indicator for elevated anxiety/depression and a potential treatment target early on in PD.

Abstract
Increased blood pressure variability (BPV) is linked to cardiovascular disease and mortality, yet few modifiable BPV risk factors are known. We aimed to assess the relationship between sleep quality and activity level on longitudinal BPV in a cohort of community-dwelling adults (age ≥18) from 17 countries. Using Withings home measurement devices, we examined sleep quality and physical activity over one year, operationalized as mean daily step count and number of sleep interruptions, both transformed into tertiles. The primary study outcome was high BPV, defined as the top tertile of systolic blood pressure standard deviation. Our cohort comprised 29,375 individuals (mean age = 58.6 years) with 127.8±90.1 mean days of measurements. After adjusting for age, gender, country, body mass index, measurement days, mean blood pressure, and total time in bed, the odds ratio of having high BPV for those in the top tertile of sleep interruptions (poor sleep) was 1.37 (95% CI, 1.28-1.47) and 1.44 (95% CI, 1.35-1.54) for those in the lowest tertile of step count (physically inactive). Combining these exposures revealed a significant excess relative risk of 0.20 (95% CI, 0.04-0.35, p = 0.012), confirming their super-additive effect. Comparing individuals with the worst exposure status (lowest step count and highest sleep interruptions, n = 2,690) to those with the most optimal status (highest step count and lowest sleep interruptions, n = 3,531) yielded an odds ratio of 2.01 (95% CI, 1.80-2.25) for high BPV. Our findings demonstrate that poor sleep quality and physical inactivity are associated with increased BPV both independently and super-additively.

Abstract
INTRODUCTION Cerebral vasospasm in patients after aneurysmal subarachnoid hemorrhage (aSAH) continues to be a major source of morbidity despite significant clinical and basic science research. The removal of blood and its degradation products from the subarachnoid space through prophylactic lumbar drainage (LD) is a favorable option. However, several studies have delivered conflicting conclusions on its efficacy after aSAH. METHODS Systematic searches of Medline, Embase, and Cochrane Central Register of Controlled Trials were performed. The primary outcome was a good functional outcome (modified Rankin scale score, 0-2). Secondary outcomes included symptomatic vasospasm, secondary cerebral infarction, and mortality. RESULTS A total of 14 studies reporting on 2473 patients with aSAH were included in the meta-analysis. Compared with the non-LD group, no significant differences were found in the rates of good functional outcomes in the LD group at discharge to 1 month (risk ratio [RR], 1.28; 95% confidence interval [CI], 0.64-2.58) or at 6 months (RR, 1.12; 95% CI, 0.97-1.41). These findings were consistent in the subgroup analyses of only randomized controlled trials or observational studies. LD was associated with lower rates of symptomatic vasospasm (RR, 0.61; 95% CI, 0.48-0.77), secondary cerebral infarction (RR, 0.59; 95% CI, 0.45-0.79), and mortality at discharge to 1 month (RR, 0.58; 95% CI, 0.41-0.82). The effect on mortality diminished at 6 months (RR, 0.70; 95% CI, 0.34-1.45). However, when analyzing only randomized controlled trials, the benefit of LD on lower rates of mortality continued even at 6 months (RR, 0.75; 95% CI, 0.58-0.99). CONCLUSIONS For aSAH patients, the use of LD is associated with benefits in the rates of vasospasm, secondary cerebral infarctions, and mortality, without an increased risk of adverse events.

Abstract
BACKGROUND Cardiac autonomic neuropathy is a highly prevalent pathology in the diabetic population, and is the leading cause of death in this population. Orthostatic hypotension is the main clinical manifestation of the disease. In some patients, this orthostatic hypotension is associated with supine hypertension, posing a therapeutic challenge since treatment of one entity may aggravate the other. The challenge is to manage each of these two hemodynamic opposites without exposing the patient to a life-threatening risk of severe hypotension or hypertension. CASE PRESENTATION We report a case of a 62-year-old ethnic Moroccan woman who has cardiovascular risk factors such as type 2 diabetes, arterial hypertension, and dyslipidemia. The patient's symptoms included dizziness, tremors, morning sickness, palpitations, and intolerance to exertion. Given her symptomatology, the patient benefited from an exploration of the autonomic nervous system through cardiovascular reactivity tests (Ewing tests), which confirmed the diagnosis of cardiac autonomic neuropathy. In addition to orthostatic hypotension, our patient had supine arterial hypertension, complicating management. To treat orthostatic hypotension, we advised the patient to avoid the supine position during the day, to raise the head of the bed during the night, and to have a sufficient fluid intake, with a gradual transition from decubitus to orthostatism and venous restraint of the lower limbs. Supine hypertension was treated with transdermal nitrates placed at bedtime and removed 1 hour before getting up. One week after the introduction of treatment, the patient reported a clear regression of functional symptoms, with an improvement in her quality of life. Improvement in symptomatology was maintained during quarterly follow-up consultations. CONCLUSIONS Cardiac autonomic neuropathy is a very common pathology in diabetic patients. It is a serious condition with a life-threatening prognosis. Its management must be individualized according to the symptomatology and profile of each patient. The treatment of patients with orthostatic hypotension and supine hypertension requires special attention to ensure that each entity is treated without aggravating the other.

Abstract
BACKGROUND The purpose of this study was to determine the detailed characteristics of dizziness in patients with de novo Parkinson's disease (PD) and the clinical implications of dizziness. METHODS Ninety-three people with de novo PD were enrolled between July 2017 and August 2022 for this retrospective study. Using each representative scale, various motor and non-motor symptoms were assessed. In addition, clinical manifestations of dizziness in those patients, including its presence, type, frequency, and duration of occurrence, were investigated. RESULTS Thirty-nine patients with de novo PD reported dizziness, with presyncope being the most common (38%). The most common frequency was several times a week (51%). The most common duration was a few seconds (67%). Multivariable logistic regression analysis showed that dizziness was more common in women than in men {odds ratio (OR): 3.3601, 95% confidence interval (CI): 1.0820-10.4351, p = 0.0361}. Dizziness was significantly related to non-motor symptoms of low global cognition (OR: 0.8372, 95% CI: 0.7285-0.9622, p = 0.0123) and severe autonomic dysfunction (OR: 1.1112, 95% CI: 1.0297-1.1991, p = 0.0067). A post-hoc analysis revealed that dizziness was only associated with cardiovascular dysautonomia (adjusted OR: 10.2377, 95% CI: 3.3053-31.7098, p < 0.0001) among several domains of dysautonomia. CONCLUSIONS About 42% of patients with de novo PD complained of dizziness. The occurrence of dizziness in those people was highly associated with female gender women, cognitive impairment, and cardiovascular dysautonomia. These results suggest that clinicians should pay close attention when patients with PD complain of dizziness.

Abstract
OBJECTIVE This article discusses the effects of myelopathy on multiple organ systems and reviews the treatment and management of some of these effects. LATEST DEVELOPMENTS Recent advances in functional electrical stimulation, epidural spinal cord stimulation, robotics, and surgical techniques such as nerve transfer show promise in improving function in patients with myelopathy. Ongoing research in stem cell therapy and neurotherapeutic drugs may provide further therapeutic avenues in the future. ESSENTIAL POINTS Treatment for symptoms of spinal cord injury should be targeted toward patient goals. If nerve transfer for upper extremity function is considered, the patient should be evaluated at around 6 months from injury to assess for lower motor neuron involvement and possible time limitations of surgery. A patient with injury at or above the T6 level is at risk for autonomic dysreflexia, a life-threatening condition that presents with elevated blood pressure and can lead to emergent hypertensive crisis. Baclofen withdrawal due to baclofen pump failure or programming errors may also be life-threatening. Proper management of symptoms may help avoid complications such as autonomic dysreflexia, renal failure, heterotopic ossification, and fractures.

Abstract
Cardiovascular autonomic neuropathy (CAN) is a frequent complication of diabetes mellitus and is associated with increased morbidity and mortality in patients with diabetes. Hence, early and correct diagnosis of CAN is crucial. Standard cardiovascular reflex rests (CARTs) have been the gold standard of CAN assessment. Originally, CARTs consisted of five reflex tests, but measuring diastolic blood pressure response to sustained handgrip exercise has no longer been suggested as an established clinical test. Increasing body of evidence suggests that isometric handgrip test should no longer be used for the evaluation of sympathetic dysfunction during cardiovascular autonomic neuropathy assessment in diabetic patients. The associations of isometric handgrip test results with parameters of hypertension and markers of hypertension-related target-organ damage in diabetic and non-diabetic individuals point toward its potential role as a screening tool to identify patients with high cardiovascular risk. The current review summarizes historical view of standard cardiovascular reflex tests and latest data on isometric handgrip test.

Abstract
BACKGROUND Cholinergic discontinuation symptoms, also known as "cholinergic rebound," from abrupt clozapine discontinuation are characterized by a range of somatic and psychiatric symptoms. OBJECTIVE The objective of this study was to describe the clinical features and management options for clozapine withdrawal-associated cholinergic rebound syndrome (henceforth referred to as CWCRS) and present an illustrative case report. METHODS Based on a literature search of the databases PubMed, OVID Medline, and Embase as well as reviewing reference lists of relevant past reviews, we carried out a systematic review of case reports on the management of CWCRS from 1946 to 2023. RESULTS We identified 10 previously published articles on the clinical management of CWCRS, with a total of 18 patients (6 female, 12 male) with an average age of 43 years (standard deviation 14). Half of the patients had a history of tardive dyskinesia. The mean dose of clozapine before discontinuation was 351 mg/day, with duration of clozapine treatment ranging from 3 weeks to 9 years. Clozapine was the most effective treatment, followed by benztropine. CONCLUSIONS Given the small number of cases and the nonexperimental nature of the available studies, this review could not provide reliable data to guide management of CWCRS. The findings, however, suggest that clozapine may be more effective than other commonly used treatment options. With the high rates of discontinuation among patients on clozapine, there is a pressing need for further research into the epidemiology, natural history, and management of clozapine withdrawal syndromes.

Abstract
Crocodile tear syndrome (CTS) is a late complication of facial nerve palsy characterized by unilateral lacrimation in response to gustatory stimulation. We present 2 cases of patients diagnosed with CTS after recovering from unilateral idiopathic facial nerve palsy. Both patients underwent transconjunctival lacrimal gland incobotulinumtoxinA injection, with doses of 5-16 units. The patients were seen in clinic for post-treatment follow-up at 2 weeks, 3 months, and 6 months. Outcomes were measured by treatment efficacy and adverse drug effects. Following treatment, both patients reported resolution of gustatory lacrimation. The patient treated with 16 U experienced transient ptosis and diplopia following injection, whereas the patient treated with 5-7.5 U experienced no adverse effects.

Abstract
INTRODUCTION Postprandial hypotension is a type of autonomic dysfunction where there is a decrease in systolic blood pressure of >20 mm HG within 2 h after eating thought to be due to poor cardiovascular compensation for splanchnic blood pooling that occurs with meals. This form of autonomic dysfunction is underdiagnosed in patients with spinal cord injury, likely in part because it can be asymptomatic. CASE PRESENTATION 26-year-old with complete cervical spinal cord injury (SCI) presented with neck pain described as severe 10/10 pain, which felt like "a rope around his neck." Pain came on during and after meals and was associated with a feeling of pressure behind his eyes, white spots in his vision along with feeling as if he was going to pass out. The caregiver noted a systolic blood pressure drop by about 30-40 points with meals and lost weight due to avoiding eating. A diagnosis of post-prandial hypotension (PPH) was made and Acarbose was started at a low dose 25 mg three times per day with meals. During follow up, the patient reported complete resolution of drops of blood pressure, neck pain, and all associated symptoms. The patient was able to eat comfortably and gained weight. DISCUSSION There are few case reports on PPH in SCI and none looking at acarbose on a young, nondiabetic person with SCI. Clinicians should be aware that PPH can occur in young otherwise healthy people with SCI. Further research is needed on PPH, including the use of acarbose, in the SCI population.

Abstract
OBJECTIVE To retrospectively describe ocular abnormalities reported in dogs with presumed dysautonomia. ANIMALS 79 dogs with dysautonomia. METHODS Medical records from the Kansas State University Veterinary Health Center from 2004 to 2021 were reviewed for dogs with a clinical or histopathologic diagnosis of canine dysautonomia (CD). Ophthalmic exam abnormalities, nonocular clinical signs, and outcomes were recorded. RESULTS Most dogs (73/79 [92.4%]) with CD exhibited at least 1 ocular abnormality. The most common ocular abnormalities were diminished pupillary light reflexes (PLRs) in 55 of 79 (69.6%) dogs and elevation of the third eyelids in 51 of 79 (64.6%) dogs. Schirmer tear test values were bilaterally decreased in 32 of 56 (57.1%) dogs. Other ocular abnormalities included resting mydriasis, ocular discharge, photophobia, blepharospasm, corneal ulceration, and conjunctival vessel pallor. The most common nonocular clinical signs were vomiting or regurgitation in 69 of 79 (87.3%) and diarrhea in 34 of 79 (43.0%) dogs. Pharmacologic testing with dilute 0.01%, 0.05%, or 0.1% pilocarpine yielded pupillary constriction in 42 of 51 (82.4%) dogs. Thirty-two of 79 (40.5%) dogs survived to discharge. Resolution of ocular abnormalities was variable. CLINICAL RELEVANCE Ophthalmic abnormalities such as diminished PLRs, elevation of the third eyelids, and decreased tear production are commonly associated with CD and provide support for its antemortem clinical diagnosis, though dogs with normal PLRs can be diagnosed with the disease. Pharmacologic testing with dilute topical pilocarpine in dogs with clinical signs suggestive of dysautonomia supports a diagnosis of CD. Ophthalmic abnormalities may improve or resolve over time.

Abstract
Traumatic and non traumatic spinal cord injury are rare and an orphan disease in comparison to common diseases. Those affected represent a very special patient population in the treatment even at the site of the accident and in emergency medicine and require a high level of professional expertise. The rehabilitation with the complexity of a spinal cord injury can only succeed with a multiprofessional team that is less focused on the often similar diagnoses according to the International Classification of Diseases (ICD) but on functional disorders and associated activity impairments. Only then the best possible integration and participation/inclusion in sociocultural and professional life can be achieved. In addition to the importance of classical physiotherapy and occupational therapy, this article highlights important but often missing team players, such as neurourology and electrical stimulation. In addition, the problems of frequent and some less recognized complications, such as autonomic dysfunction and the benefits of airway management are highlighted. For a comprehensive overview of rehabilitation in spinal cord injury, reference textbooks and guidelines are recommended that are cited in the text.

Abstract
The relationship between urinary endothelial growth factor (uEGF) and cardiovascular autonomic neuropathy (CAN) in adults with type 1 diabetes was evaluated. uEGF levels at baseline and standardized CAN measures were collected at baseline and annually for 3 years for type 1 diabetes adults. Linear regression analysis and linear mixed effects model were used for analysis. In this cohort (n = 44, 59% women, mean ± standard deviation age 34 ± 13 years and diabetes duration 14 ± 6 years), lower baseline uEGF levels correlated with lower baseline expiration : inspiration ratios (P = 0.03) and greater annual declines in Valsalva ratios (P = 0.02) in the unadjusted model, and correlated with lower low-frequency power : high-frequency power ratios (P = 0.01) and greater annual changes in low-frequency power : high-frequency power ratios (P = 0.01) after adjustment for age, sex, body mass index, and hemoglobin A1C. In conclusion, baseline uEGF levels correlate to baseline and longitudinal changes in CAN indices. A large-scale, long-term study is needed to validate uEGF as a reliable CAN biomarker.

Abstract
CONTEXT Hyperglycemia and autonomic dysfunction are bidirectionally related. OBJECTIVE We investigated the association of longitudinal evolution of heart rate variability (HRV) with incident type 2 diabetes (T2D) among the general population. METHODS We included 7630 participants (mean age 63.7 years, 58% women) from the population-based Rotterdam Study who had no history of T2D and atrial fibrillation at baseline and had repeated HRV assessments at baseline and during follow-up. We used joint models to assess the association between longitudinal evolution of heart rate and different HRV metrics (including the heart rate-corrected SD of the normal-to-normal RR intervals [SDNNc], and root mean square of successive RR-interval differences [RMSSDc]) with incident T2D. Models were adjusted for cardiovascular risk factors. Bidirectional Mendelian randomization (MR) using summary-level data was also performed. RESULTS During a median follow-up of 8.6 years, 871 individuals developed incident T2D. One SD increase in heart rate (hazard ratio [HR] 1.20; 95% CI, 1.09-1.33), and log(RMSSDc) (HR 1.16; 95% CI, 1.01-1.33) were independently associated with incident T2D. The HRs were 1.54 (95% CI, 1.08-2.06) for participants younger than 62 years and 1.15 (95% CI, 1.01-1.31) for those older than 62 years for heart rate (P for interaction <.001). Results from bidirectional MR analyses suggested that HRV and T2D were not significantly related to each other. CONCLUSION Autonomic dysfunction precedes development of T2D, especially among younger individuals, while MR analysis suggests no causal relationship. More studies are needed to further validate our findings.

Abstract
OBJECTIVE To assess autonomic function and investigate factors related to its dysfunction in patients with temporomandibular disorders (TMD) from a biopsychosocial perspective. METHODS Seventy-six patients with TMD were investigated by clinical examination and questionnaires concerning biopsychosocial aspects (The Brief Pain Inventory, the Pain Catastrophizing Scale, and the Symptom Checklist-90-Revised) and autonomic dysfunction (The COMPASS 31). RESULTS Seventy-one patients were included in the study. The result of multiple regression analysis showed that four variables (sex, depression, age, and pain interference) were significantly associated with autonomic dysfunction. Increased orthostatic intolerance and bladder dysfunction were observed in females and males, respectively. Younger age was associated with higher orthostatic intolerance, while higher pain interference was associated with higher secretomotor dysfunction and bladder dysfunction. Further, higher depression scores were linked to higher scores in the gastrointestinal subdomain. CONCLUSION Autonomic dysfunction may affect TMD-related pain in the context of a biopsychosocial perspective.

Abstract
Parkinson's disease (PD) is a common neurodegenerative disease characterized by motor symptoms, including bradykinesia, resting tremor, and progressive rigidity. More recently, non-motor symptoms of PD, such as pain, depression and anxiety, and autonomic dysfunction, have attracted increasing attention from scientists and clinicians. As one of non-motor symptoms, pain has high prevalence and early onset feature. Because the mechanism of PD-related pathological pain is unclear, the clinical therapy for treating PD-related pathological pain is very limited, with a focus on relieving the symptoms. This paper reviewed the clinical features, pathogenesis, and therapeutic strategies of PD-related pathological pain and discussed the mechanism of the chronicity of PD-related pathological pain, hoping to provide useful data for the study of drugs and clinical intervention for PD-related pathological pain.

Abstract
BACKGROUND Resolution of sleep disordered breathing (SDB) in typically developing children normalises heart rate variability (HRV), a measure of autonomic control, to that of non-snoring controls. Children with Down Syndrome (DS) have dampened heart rate variability (HRV) but the effect of treatment is not known. To assess the effect of improvement of SDB on autonomic control we compared HRV in children with DS whose SDB improved over 2 y, to those whose SDB did not improve. METHODS 24 children (3-19 y) had a baseline and follow-up polysomnographic study 2 y later. Improved SDB was defined as a reduction in obstructive apnea hypopnea index (OAHI) to ≤ 50% of baseline. Children were grouped into Improved (n = 12) and Unimproved (n = 12). Power spectral analysis of the ECG determined low frequency (LF), high frequency (HF) power and the LF/HF ratio. Seven children in the Improved and 2 in the Unimproved group were treated following the baseline study. RESULTS In the Unimproved group at follow-up, LF power was lower compared to baseline during N3 and Total Sleep (p < 0.05 for both). HF power was lower during REM (p < 0.05). HRV remained unchanged between studies in the Improved group. CONCLUSION Autonomic control worsened as indicated by lower LF and HF power in children whose SDB was not improved. In contrast, in those children with improved SDB, autonomic control remained the same, suggesting improvement in SDB severity prevents further worsening of autonomic control in children with DS.

Abstract
Disorders of autonomic functions are typically characterized by disturbances in multiple organ systems. These disturbances are often comorbidities of common and rare diseases, such as epilepsy, sleep apnea, Rett syndrome, congenital heart disease or mitochondrial diseases. Characteristic of many autonomic disorders is the association with intermittent hypoxia and oxidative stress, which can cause or exaggerate a variety of other autonomic dysfunctions, making the treatment and management of these syndromes very complex. In this review we discuss the cellular mechanisms by which intermittent hypoxia can trigger a cascade of molecular, cellular and network events that result in the dysregulation of multiple organ systems. We also describe the importance of computational approaches, artificial intelligence and the analysis of big data to better characterize and recognize the interconnectedness of the various autonomic and non-autonomic symptoms. These techniques can lead to a better understanding of the progression of autonomic disorders, ultimately resulting in better care and management.

Abstract
We herein report a 45-year-old man with dentatorubropallidoluysian atrophy (DRPLA) who presented with mild dementia, ataxia, and involuntary movement and developed constipation, dysuria, and orthostatic hypotension. Thermography revealed an abnormal thermal response of the skin to cold stimulation. Skin temperature reflects the skin blood flow and is regulated by the sympathetic nervous system. Thermography is currently used to study diseases associated with vasomotor dysfunction of the skin. The thermography results suggested the possibility of autonomic dysfunction. Although little is known regarding autonomic dysfunction in DRPLA, this report demonstrates the importance of autonomic dysfunction in DRPLA.

Abstract
This case demonstrates how orthostatic hypotension in the absence of typical symptoms of light-headedness/dizziness when changing posture, can contribute to the burden of falls in Parkinson's disease. At least one-third of people with severe orthostatic hypotension do not report typical symptoms, and this figure appears to be higher in patients with Parkinson's disease. This is important clinically as it can increase the difficulty in ascribing falls to orthostatic hypotension, especially given the other competing reasons in Parkinson's disease and orthostatic hypotension symptoms can act as a prompt for the patient to act to prevent falls-related injuries. There is a clinical requirement, therefore, to screen for and manage orthostatic hypotension in patients with Parkinson's disease to prevent falls, even in those who do not report typical symptoms.

Abstract
OBJECTIVE The role of hemorrhage volume in risk of vasospasm, delayed cerebral ischemia (DCI), and poor outcomes after aneurysmal subarachnoid hemorrhage (SAH) is well established. However, the relative contribution of blood within individual compartments is unclear. We present an automated technique for measuring not only total but also volumes of blood in each major compartment after SAH. METHODS We trained convolutional neural networks to identify compartmental blood (cisterns, sulci, and ventricles) from baseline computed tomography scans of patients with SAH. We compared automated blood volumes against traditional markers of bleeding (modified Fisher score [mFS], Hijdra sum score [HSS]) in 190 SAH patients for prediction of vasospasm, DCI, and functional status (modified Rankin Scale) at hospital discharge. RESULTS Combined cisternal and sulcal volume was better correlated with mFS and HSS than cisternal volume alone (ρ = 0.63 vs. 0.58 and 0.75 vs. 0.70, P < 0.001). Only blood volume in combined cisternal plus sulcal compartments was independently associated with DCI (OR 1.023 per mL, 95% CI 1.002-1.048), after adjusting for clinical factors while ventricular blood volume was not. Total and specifically sulcal blood volume was strongly associated with poor outcome (OR 1.03 per mL, 1.01-1.06, P = 0.006 and OR 1.04, 1.00-1.08 for sulcal) as was HSS (OR 1.06 per point, 1.00-1.12, P = 0.04), while mFS was not (P = 0.24). CONCLUSIONS An automated imaging algorithm can measure the volume of bleeding after SAH within individual compartments, demonstrating cisternal plus sulcal (and not ventricular) blood contributes to risk of DCI/vasospasm. Automated blood volume was independently associated with outcome, while qualitative grading was not.

Abstract
BACKGROUND Identification of metabolomics profile in subjects with different blood pressure, including normal blood pressure, elevated blood pressure, stage 1 hypertension, and stage 2 hypertension, would be a promising strategy to understand the pathogenesis of hypertension. Thus, we conducted this study to investigate the association of plasma acylcarnitines and amino acids with hypertension in a large Iranian population. METHODS 1200 randomly selected subjects from the national survey on the Surveillance of Risk Factors of Non-Communicable Diseases in Iran (STEPs 2016) were divided into four groups based on the ACC/AHA hypertension criteria: normal blood pressure (n = 293), elevated blood pressure (n = 135), stage 1 hypertension (n = 325), and stage 2 hypertension (n = 447). Plasma concentrations of 30 acylcarnitines and 20 amino acids were measured using a targeted approach with flow-injection tandem mass spectrometry. Univariate and multivariate logistic regression analysis was applied to estimate the association between metabolites level and the risk of hypertension. Age, sex, BMI, total cholesterol, triglyceride, HDL cholesterol, fasting plasma glucose, use of oral glucose-lowering drugs, statins, and antihypertensive drugs were adjusted in regression analysis. RESULTS Of 50 metabolites, 34 were associated with an increased likelihood of stage 2 hypertension and 5 with a decreased likelihood of stage 2 hypertension. After full adjustment for potential confounders, 5 metabolites were still significant risk markers for stage 2 hypertension including C0 (OR = 0.75; 95%CI: 0.63, 0.90), C12 (OR = 1.18; 95%CI: 1.00, 1.40), C14:1 (OR = 1.20; 95%CI: 1.01, 1.42), C14:2 (OR = 1.19; 95%CI: 1.01, 1.41), and glycine (OR = 0.81; 95%CI: 0.68, 0.96). An index that included glycine and serine also showed significant predictive value for stage 2 hypertension after full adjustment (OR = 0.86; 95%CI: 0.75, 0.98). CONCLUSIONS Five metabolites were identified as potentially valuable predictors of stage 2 hypertension.

Abstract
PURPOSE OF REVIEW This article reviews the pathophysiology, epidemiology, clinical features, diagnosis, and treatment of Lambert-Eaton myasthenic syndrome (LEMS) and botulism, presynaptic disorders of neuromuscular transmission in which rapid diagnosis improves long-term outcomes. RECENT FINDINGS Therapy for LEMS has seen significant advances in recent years due to the approval of amifampridine-based compounds. LEMS is likely still underdiagnosed, particularly when no underlying malignancy is identified. Clinicians must have a strong suspicion for LEMS in any patient presenting with proximal weakness and autonomic dysfunction. Botulism is another rare disorder of presynaptic neuromuscular transmission that is most commonly associated with improper storage or preservation of food products. Over the past 2 decades, wound botulism has been increasingly reported among users of black tar heroin. A high degree of clinical suspicion and electrodiagnostic studies can be beneficial in distinguishing botulism from other acute neurologic disorders, and early involvement of state and federal health authorities may assist in confirming the diagnosis and obtaining treatment. When botulism is suspected, electrodiagnostic studies can provide clinical evidence of disordered neuromuscular transmission in advance of serologic confirmation, and providers should not wait for confirmation of the diagnosis to initiate treatment. SUMMARY A targeted clinical history and a thorough neurologic examination with support from serologic and electrodiagnostic studies are key to early diagnosis of LEMS and botulism. Early diagnosis of both conditions creates opportunities for therapy and improves outcomes.

Abstract
OBJECTIVE Cardiovascular autonomic neuropathy is a known complication in type 2 diabetes (T2D). However, the extent of sympathetic dysfunction and its relation to blood pressure (BP) dysregulation is insufficiently studied. We therefore assessed the cardiovascular sympathetic function using a standardized autonomic test-battery. RESEARCH DESIGN AND METHODS Forty T2D patients (mean age and duration of diabetes ±SD, 65.5 ± 7.3 and 9.5 ± 4.2 years) and 40 age- and gender-matched controls were examined through autonomic testing, assessing cardiovascular responses to deep breathing, Valsalva maneuver and tilt-table testing. Additionally, 24-hour oscillometric BP and self-reported autonomic symptoms on COMPASS-31 questionnaire was recorded. RESULTS Patients with T2D had reduced parasympathetic activity with reduced deep breathing inspiratory:expiratory-ratio (median [IQR] T2D 1.11 [1.08-1.18] vs. controls 1.18 [1.11-1.25] (p = 0.01)), and reduced heart rate variability (p < 0.05). We found no differences in cardiovascular sympathetic function measured through BP responses during the Valsalva maneuver (p > 0.05). 24-hour-BP detected reduced night-time systolic BP drop in T2D (9.8 % ± 8.8 vs. controls 15.8 % ± 7.7 (p < 0.01)) with more patients having reverse dipping. Patients with T2D reported more symptoms of orthostatic intolerance on the COMPASS-31 (p = 0.04). CONCLUSIONS Patients with T2D showed reduced parasympathetic activity but preserved short-term cardiovascular sympathetic function, compared to controls, indicating autonomic dysfunction with predominantly parasympathetic impairment. Despite this, T2D patients reported more symptoms of orthostatic intolerance in COMPASS-31 and had reduced nocturnal BP dipping, indicating that these are not a consequence of cardiovascular sympathetic dysfunction.

Abstract
INTRODUCTION Parkinson's disease (PD) has variable progression; identifying determinants of functional decline in PD is needed for accurate prognostication. Autonomic symptoms can result from dopaminergic therapy, but may also independently predict functional decline. METHODS The sample included individuals with newly-diagnosed PD in Parkinson's Progression Markers Initiative. Autonomic symptoms were measured with the Scales-for-Outcomes-in-Parkinson's-Disease-Autonomic (SCOPA-AUT). Presence/absence of autonomic symptoms for SCOPA-AUT total scale and seven subscales was defined and baseline demographic/clinical data were compared between groups with and without autonomic symptoms. Time-to-functional-dependence, or Schwab-and-England Activities-of-Daily-Living (SE-ADL) ≤70, was compared between groups using hazard models, adjusting for covariates including time-varying levodopa-equivalent daily dosage (LEDD). If a subscale was associated with a significant subhazard ratio (SHR), hazard models for items in that subscale were generated and gender was evaluated as an effect modifier. RESULTS 399 participants were included. Over a median of 72 months (range 6-84), 91 (22.81%) reached SE-ADL≤70. SCOPA-AUT total/gastrointestinal/urinary/pupillomotor scales were associated with SE-ADL≤70; respective multivariable SHRs (95% CI, p-value) were 1.98 (1.06-3.70, .03), 1.71 (1.04-2.81, .03), 1.94 (1.25-3.01, <.01), 2.56 (1.24-5.31, .01). Individual items in the gastrointestinal and urinary scales drove associations. Urinary scale associations were seen in males only. CONCLUSIONS Symptoms of gastrointestinal, urinary, pupillomotor dysfunction are associated with functional decline risk in PD, independent of dopaminergic therapy. Detailed assessments of autonomic symptomatology should be utilized in studies attempting to refine predictive models of PD progression.

Abstract
Cardiac autonomic neuropathy (CAN) is a serious complication of diabetes mellitus that can predispose patients to higher risk for cardiovascular death. The aim of the present study was to evaluate the presence of cardiac autonomic neuropathy and sudomotor dysfunction in patients with newly diagnosed carbohydrate disturbances (prediabetes or diabetes) and to assess their relationship to metabolic disturbances and cardiovascular risk. In the present study, we included 160 patients -78 with obesity without carbohydrate disturbances, 52 with prediabetes, and 30 with newly diagnosed diabetes. CAN was diagnosed using cardiovascular reflex tests and sudomotor function was evaluated by SUDOSCAN. Cardiovascular risk was calculated using SCORE and FRMINGHAM risk scores. The prevalence of cardiac autonomic neuropathy was significantly higher in patients with newly diagnosed diabetes. Independently of their glycemic status, the patients who had blood glucose on the 60th-minute of OGTT>8.5 mmol/l had significantly higher prevalence of cardiac autonomic neuropathy (30.2% vs 15.6%, р=0.044). Patients with high cardiovascular risk according to FRAMINGHAM and SCORE had worse heart rate variability scores. Autonomic neuropathy risk assessed by SUDOSCAN was a good predictor for the presence of CAN. In conclusion, CAN has a higher prevalence on patients with newly diagnosed diabetes compared to prediabetic and normoglycemic subjects, while the patients with blood glucose>8.5 mmol/l on the 60th-minute of OGTT have higher prevalence of CAN independently of their glycemic status. SUDOSCAN testing can be used to assess the risk of CAN and to select patients that should undergo further testing.

Abstract
AIMS We aimed to evaluate the contemporary prevalence of and risk factors for symptomatic diabetic autonomic neuropathy (DAN) in participants with type 1 diabetes (T1D) enrolled in the T1D Exchange Clinic Registry. METHODS DAN symptoms and severity were assessed with the Survey of Autonomic Symptoms (SAS) in adults with ≥5 years of T1D participating in the T1D Exchange from years 2010-2017. Associations of demographic, clinical, and laboratory factors with symptomatic DAN were assessed. RESULTS Of the 4919 eligible T1D participants, 965 (20%) individuals completed the SAS questionnaire [mean age 40 ± 17 years, median diabetes duration 20 years (IQR: 13,34), 64% female, 90% non-Hispanic White, and 82% with private insurance]. DAN symptoms were present in 166 (17%) of responders with 72% experiencing moderate severity symptoms or worse. Symptomatic DAN participants had higher hemoglobin A1c (p = 0.03), longer duration (p = 0.004), were more likely to be female (p = 0.03), and more likely to have lower income (p = 0.03) versus no DAN symptoms. Symptomatic DAN was associated with diabetic peripheral neuropathy (p < 0.0001), smoking (p = 0.002), cardiovascular disease (p = 0.02), depression (p < 0.001), and opioid use (p = 0.004). CONCLUSIONS DAN symptoms are common in T1D. Socioeconomic factors and psychological comorbidities may contribute to DAN symptoms and should be explored further.

Abstract
Some patients with Parkinson's disease and multiple system atrophy suffer from orthostatic hypotension as a result of cardiovascular autonomic dysfunction. Other complicated dysfunctions, such as spinal hypertension, hinder the management of orthostatic hypotension. A combination of pharmacological and non-pharmacological interventions is required for successful treatment. In this article, I first discuss general matters regarding orthostatic hypotension, after which I describe refractory cases of orthostatic hypotension I have encountered in clinical practice.

Abstract
Many people, particularly elderly, experience dizziness upon standing. It is important to always measure the blood pressure and heart rate in the supine and standing position in these patients. In case of orthostatic hypotension with an insufficient increase in heart rate, one has to consider autonomic dysfunction. Alpha-synucleopathies are frequent causes of autonomic dysfunction, including Parkinson's disease, Pure Autonomic Failure and Multiple System Atrophy. The quality of life can significantly be improved in patients with autonomic dysfunction due to life-style measures (increased salt and water intake, compressive stockings, head-up sleeping) and medication to increase blood pressure (fludrocortisone, midodrine). There is often a considerable delay in the diagnosis of autonomic dysfunction, which prevents adequate treatment. The main message of this paper is that we should all search for orthostatic hypotension in patients with dizziness and, in case of insufficient heart rate increase, refer these patients for autonomic function testing.

Abstract
Multiple system atrophy (MSA) is a neurodegenerative disease characterized by both autonomic and motor dysfunction (cerebellar ataxia and/or parkinsonism). The former presents with symptoms associated with urological, cardiovascular, gastrointestinal, auditory, and respiratory disorders, among others. Therefore, multidisciplinary collaboration between neurologists and specialists from the aforementioned disciplines is extremely important for the management of these patients. Optimal management of autonomic disorders in patients with MSA can significantly maximize patients' quality of life.

Abstract
Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) is a rare cause of syndromic obesity with risk of cardiorespiratory arrest and neural crest tumor. No ROHHAD-specific genetic test exists at present. Rapid weight gain of 20-30 pounds, typically between ages 2-7 years in an otherwise healthy child, followed by multiple endocrine abnormalities herald the ROHHAD phenotype. Vigilant monitoring for asleep hypoventilation (and later awake) is mandatory as hypoventilation and altered control of breathing can emerge rapidly, necessitating artificial ventilation as life support. Recurrent hypoxemia may lead to cor pulmonale and/or right ventricular hypertrophy. Autonomic dysregulation is variably manifest. Here we describe the disease onset with "unfolding" of the phenotype in a child with ROHHAD, demonstrating the presentation complexity, need for a well-synchronized team approach, and optimized management that led to notable improvement ("refolding") in many aspects of the child's ROHHAD phenotype over 10 years of care.

Abstract
BACKGROUND Syncope is not a common manifestation of COVID-19, but it may occur in this context and it can be the presenting symptom in some cases. Different mechanisms may explain the pathophysiology behind COVID-19 related syncope. In this report, we aimed to examine the current frequency and etiology of syncope in COVID-19. METHODS A systematic review across PubMed, ISI Web of Knowledge and SCOPUS was performed, according to PRISMA guidelines, in order to identify all relevant articles regarding both COVID-19 and syncope. RESULTS We identified 136 publications, of which 99 were excluded. The frequency of syncope and pre-syncope across the selected studies was 4.2% (604/14,437). Unexplained syncope was the most common type (87.9% of the episodes), followed by reflex syncope (7.8% of the cases). Orthostatic hypotension was responsible for 2.2% of the cases and syncope of presumable cardiac cause also accounted for 2.2% of cases. Arterial hypertension was present in 52.0% of syncope patients. The use of angiotensin receptor blockers or angiotensin converting enzyme inhibitors were not associated with an increased incidence of syncope (chi-square test 1.07, p 0.30), unlike the use of beta-blockers (chi-square test 12.48, p < 0.01). CONCLUSION Syncope, although not considered a typical symptom of COVID-19, can be associated with it, particularly in early stages. Different causes of syncope were seen in this context. A reevaluation of blood pressure in patients with COVID-19 is suggested, including reassessment of antihypertensive therapy, especially in the case of beta-blockers.

Abstract
With the advent of novel cancer therapeutics and improved screening, more patients are surviving a cancer diagnosis or living longer with advanced disease. Many of these treatments have associated cardiovascular toxicities that can manifest in both an acute and a delayed fashion. Arrhythmias are an increasingly identified complication with unique management challenges in the cancer population. The purpose of this scientific statement is to summarize the current state of knowledge regarding arrhythmia identification and treatment in patients with cancer. Atrial tachyarrhythmias, particularly atrial fibrillation, are most common, but ventricular arrhythmias, including those related to treatment-induced QT prolongation, and bradyarrhythmias can also occur. Despite increased recognition, dedicated prospective studies evaluating true incidence are lacking. Moreover, few studies have addressed appropriate prevention and treatment strategies. As such, this scientific statement serves to mobilize the cardio-oncology, electrophysiology, and oncology communities to develop clinical and scientific collaborations that will improve the care of patients with cancer who have arrhythmias.

Abstract
AIM The present study aims to determine the prevalence and association of cardiac autonomic neuropathy (CAN) with some traditional cardio-metabolic risk factors in adults with type 1 diabetes (T1D). MATERIAL AND METHODS 235 adults with T1D, divided into three groups according to diabetes duration, were recruited in this cross-sectional study from May 2017 till December 2018. Anthropometric parameters and blood pressure were measured. Lipids, liver enzymes, uric acid, creatinine, HbA1c and high sensitive C-reactive protein (hsCRP) were measured at fasting. Albumin/creatinine ratio (ACR) was measured in a first spot urine sample. Body composition was evaluated using bio-impedance analysis, Inbody720 (Biospace, USA). Advanced glycation end products (AGEs) were assessed by autofluorescence method, AGE Reader (Diagnoptics, The Netherlands). CAN was assessed by ANX-3.0 monitoring technology (ANSAR Medical Technologies, Inc., Philadelphia, PA), applying standard clinical tests. 2005 IDF and 2009 JIS definitions were used to define Metabolic Syndrome (MetS). RESULTS The prevalence of CAN was 23% and increased with diabetes duration. Sympathetic activity was independently related to age, albumin/creatinine ratio (ACR) and total body fat mass, and parasympathetic activity - to age and ACR. Elevated hsCRP, AGEs and body fat, diabetic retinopathy and nephropathy, as well as hypertension, dyslipidemia and metabolic syndrome were found to increase the risk of CAN in T1D. CONCLUSION CAN appears to be a common complication of T1D, especially with longer duration, and is found to be related to diabetic microvascular disease and metabolic syndrome components.

Abstract
OBJECTIVES To compare the clinical features of autonomic dysfunction using the SCOPA-AUT questionnaire in untreated patients with restless legs syndrome (RLS) with controls, to identify factors associated with more severe autonomic symptoms, and to assess the effect of medication in patients. METHODS The SCOPA-AUT questionnaire that evaluates cardiovascular, gastrointestinal, urinary, thermoregulatory, pupillomotor, and sexual dysfunctions was completed by 409 consecutive untreated patients with RLS (54.1 ± 14.5 y.o; 265 women) and 331 controls (59.0 ± 17.0; 161 women). Clinical and polysomnographic data were assessed in all patients. A subgroup of 57 patients were evaluated a second time after treatment (mostly dopaminergic agonist) after an interval of 0.88 ± 1.42 year. RESULTS Compared to controls, untreated patients with RLS were younger, more often women, obese, with increased cardiovascular diseases (CVD). The SCOPA-AUT total score was higher in patients than controls in unadjusted and adjusted models. Patients had more autonomic symptoms in all subdomains of the scale (except for sexual dysfunction in men). These results were confirmed in a subgroup of 259 cases and age-sex-matched controls. Female gender, obesity, RLS severity, diabetes mellitus, CVD, sleepiness, insomnia and depressive symptoms but neither periodic legs movements during sleep (PLMS) nor objective sleep parameters were associated with high scores. Despite RLS and PLMS improvement, medication did not change total and subdomain scores. CONCLUSIONS Patients with RLS have frequent and large spectrum of autonomic symptoms, without effect of PLMS, sleep fragmentation and medication. These results suggest a global autonomic dysfunction in RLS that should be assessed more systematically in severe patients.

Abstract
BACKGROUND Although autonomic imbalance is associated with an increased risk for metabolic disease, its effects on nonalcoholic fatty liver disease (NAFLD) remains unclear. We aimed to evaluate whether autonomic dysfunction predicts the risk for nonalcoholic fatty liver disease (NAFLD). METHODS A total of 33,899 participants without NAFLD who underwent health screening programs between 2011 and 2018 were enrolled. NAFLD was identified by ultrasonography. Autonomic activity was estimated using heart rate variability (HRV). Time domain [standard deviation of the normal-to-normal interval (SDNN) and root mean square difference (RMSSD)]; frequency domain [total power (TP), low frequency (LF), and high frequency (HF), and LF/HF ratio were analyzed. FINDINGS A total 6,466 participants developed NAFLD within a median of 5.7 years. Subjects with incident NAFLD showed decreased overall autonomic modulation and vagal activity with lowered SDNN, RMSSD, HF, normalized HF, compared to those without NAFLD. As the SDNN, RMSSD, TP, LF, and HF tertiles increased, the risk of NAFLD decreased with tertile 1 being the reference group [the hazard ratios (95% confidence intervals) of tertile 3 were 0.90 (0.85-0.96), 0.83 (0.78-0.88), 0.91 (0.86-0.97), 0.93 (0.87-0.99) and 0.89 (0.83-0.94), respectively] after adjusting for potential confounders. The risk for NAFLD was significantly higher in subjects in whom sustained elevated heart rate, normalized LF, and LF/HF ratio values than in those with sustained decrease in these parameters during follow-up. CONCLUSIONS Overall autonomic imbalance, decreased parasympathetic activity, and recently increased sympathetic activity might increase the risk of NAFLD.

Abstract
PURPOSE OF REVIEW This article reviews disorders of sweating, including hyperhidrosis and anhidrosis due to central or peripheral autonomic nervous system causes. RECENT FINDINGS Disorders of thermoregulation and sweating may manifest with hyperhidrosis or hypohidrosis/anhidrosis. Primary disorders of hyperhidrosis may significantly impact quality of life yet tend to be benign. Many sweating disorders present with compensatory hyperhidrosis due to areas of anhidrosis. Anhidrosis may occur due to either central or peripheral damage to the autonomic nervous system. The thermoregulatory control of sweating involves central pathways from the hypothalamus to the brainstem and then spinal cord as well as projections to peripheral structures, including the sympathetic chain ganglia, peripheral nerves, and eccrine sweat glands. Disruption at any point of this pathway may lead to impaired sweating. Characterization of sweating dysfunction helps localize different autonomic disorders to guide diagnosis and may allow for evaluation of treatment effect. SUMMARY Sweating dysfunction manifests in myriad ways, including essential hyperhidrosis, complete anhidrosis with heat intolerance, and compensatory hyperhidrosis due to anhidrosis, and often indicates involvement of underlying central or peripheral autonomic dysfunction.

Abstract
PURPOSE OF REVIEW This article reviews the α-synucleinopathies pure autonomic failure, multiple system atrophy, dementia with Lewy bodies, and Parkinson disease with respect to autonomic failure. RECENT FINDINGS The pattern and severity of autonomic involvement in the synucleinopathies is related to differences in cellular deposition and neuronal populations affected by α-synuclein aggregation, which influences the degree and manifestation of autonomic failure. Clinical and laboratory autonomic features distinguish the different synucleinopathies based on pattern and severity. These features also determine which patients are at risk for evolution from pure autonomic failure to the synucleinopathies with prominent motor involvement, such as multiple system atrophy, dementia with Lewy bodies, or Parkinson disease. SUMMARY Autonomic failure is a key feature of the synucleinopathies, with varying type and degree of dysfunction from predominantly peripheral involvement in the Lewy body disorders to central involvement in multiple system atrophy.

Abstract
PURPOSE OF REVIEW This article provides an up-to-date assessment of the role of skin biopsy in the evaluation of autonomic disorders. The standard methodology for completing a skin biopsy, the anatomic structures of interest detected within a skin biopsy, and the disease states in which skin biopsies may provide valuable information are reviewed. RECENT FINDINGS Several recent advances in the studies of hereditary amyloidosis and the various degenerative synucleinopathies have demonstrated that simple skin biopsies can provide valuable pathologic evidence of neurologic disease. In addition to diagnosis of the underlying disorder, skin biopsies provide a quantitative structural measurement of the associated autonomic damage. SUMMARY Skin biopsies are making great inroads into the study of autonomic and peripheral nerve disorders. Complex immunohistochemical staining protocols are challenging to complete, but the rich data derived from these studies in the diagnosis and monitoring of different disease states suggest that the role of skin biopsies in the study of the autonomic nervous system will continue to expand in the years to come.

Abstract
BACKGROUND Sclerostin inhibits bone formation and its expression is upregulated in the vasculature during the arterial calcification process as a counterregulatory mechanism preventing further calcification. Lower extremity arterial calcification (LEAC) is common in neuropathic patients with type 2 diabetes (T2DM). Herein, we investigated for associations between plasma sclerostin levels and diabetic neuropathy as well as LEAC in subjects with T2DM. METHODS A total of 74 individuals with and 76 without T2DMwere recruited. Plasma sclerostin levels were measured by ELISA. Diagnosis of cardiac autonomic neuropathy (CAN) was based on the battery of the four autonomic tests, while of somatosensory peripheral neuropathy (DPN) on neuropathy symptom score and neuropathy disability score. LEAC was assessed with conventional ankle and foot x-rays. RESULTS Plasma sclerostin levels were higher in participants with LEAC vs. those without LEAC in both diabetes and non-diabetes cohorts (p = 0.035 and p = 0.003, respectively). In the diabetes cohort, patients with CAN, but not with DPN, had higher sclerostin levels when compared with those without CAN (p < 0.001). Multivariate analysis in the diabetes cohort demonstrated that sclerostin levels were associated positively with CAN and LEAC, while in the non-diabetes cohort there was a trend for a positive association with male gender and presence of LEAC. CONCLUSION Plasma sclerostin levels are increased in individuals with LEAC irrespectively of diabetes status. In addition, plasma sclerostin concentrations are associated independently with LEAC and CAN in people with T2DM.

Abstract
INTRODUCTION Blood flow-restricted exercise (BFRE) appears to hold considerable potential in spinal cord injury (SCI) rehabilitation, due to its ability to induce beneficial functional changes and morphological alterations from low-intensity, low-load exercise. However, it remains unclear if this training approach is feasible and safe in individuals with autonomic dysreflexia (AD). CASE PRESENTATION A 23-year-old male with traumatic, cervical (C6), motor-complete (AIS: B) SCI and diagnosed AD completed eight sessions of BFRE for the upper extremities over 4 weeks. Blood pressure and heart rate recordings and perceptual pain responses were collected repeatedly during exercise. Blood samples were drawn pre- and post-training. Training was carried out in a neurorehabilitation hospital setting with appertaining medical staff readiness, and was supervised by a physiotherapist with expertise in AD in general as well as prior knowledge of the present patient's triggers and symptoms. Four incidences of AD (defined as systolic blood pressure increase >20 mmHg) were recorded across all training sessions, of which one was symptomatic. The patient's blood profile did not change considerably from pre- to post-training sessions. Self-reported average pain during training corresponded from "mild" to "moderate". DISCUSSION The patient was able to perform 4 weeks of BFRE, but encountered episodes of AD. Similarly, two AD episodes were registered during a single conventional, free-flow resistance training session. Evidence from clinically controlled safety studies is needed in order to establish if and how BFRE can be applied in a rehabilitation strategy in SCI individuals with neurological level of injury at or above T6 level.

Abstract
We present the case of a 34-year-old patient with severe head trauma and severe brain involvement. The patient deteriorated progressively and required several reinterventions for bleeding and brain herniation. We were consulted by neurosurgery due to irregular blood pressure control despite treatment with calcium antagonists. The patient had associated diaphoresis, tachypnoea and tachycardia, together with persistent high-grade fever with no microbiological evidence. Laboratory tests showed normal kidney function, with no proteinuria and no signs of left ventricular hypertrophy to suggest previous arterial hypertension. This led us to consider sympathetic hyperactivity syndrome as a first possible diagnosis due to severe neurological damage. In line with this suspicion, antihypertensive therapy was initiated which included non-cardioselective beta-blockers, alpha-2 agonists, benzodiazepines and GABA receptor agonists. Thus, we were able to improve the labile blood pressure levels, which supports the diagnosis.

Abstract
CONTEXT Hypoglycemia attenuates cardiovascular homeostatic autonomic control. This attenuation, known as the cardiovascular component of hypoglycemia-associated autonomic failure (HAAF), is characterized most notably by decreased baroreflex sensitivity (BRS) that begins during hypoglycemia and persists until at least the next day, despite return to euglycemia. Understanding the mechanisms underlying this reduction in BRS is important because BRS attenuation is associated with increased morbidity and mortality. OBJECTIVE The objective of this work is to investigate the role of the adrenocorticotropin (ACTH)-adrenal axis in decreasing BRS. We tested the hypothesis that infusion of ACTH 1-24 (cosyntropin), as compared to placebo, would acutely suppress BRS, and that this decrease in BRS would be present the next day. DESIGN A double-blind, placebo-controlled, random-order, cross-over study was conducted. SETTING This study took place in a clinical research center. PARTICIPANTS Participants included healthy men and women. INTERVENTIONS Interventions included an intravenous infusion of cosyntropin (70 μg/hour for 2.5 hours in the morning and again in the early afternoon) vs normal saline placebo. MAIN OUTCOME MEASURES Outcome measures included BRS during and 16 hours after cosyntropin vs placebo infusions. RESULTS Cosyntropin infusion attenuated BRS (mm Hg/ms) as compared to placebo (baseline 17.8 ± 1.38 vs 17.0 ± 2.07; during 14.4 ± 1.43 vs 17.3 ± 1.65; and next day 14.8 ± 1.42 vs 18.9 ± 2.04; P < .05, time by treatment, analysis of variance). BRS was decreased during the final 30 minutes of the morning cosyntropin infusion as compared to baseline (P < .01) and remained suppressed the next day (16 hours after afternoon infusion) (P < .025). Placebo infusion did not significantly change BRS. Corrected QT interval was not affected. CONCLUSIONS ACTH attenuates BRS, raising the possibility that hypoglycemia-induced increases in ACTH may contribute to the cardiovascular component of HAAF.

Abstract
CONTEXT Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, autonomic dysregulation and neural crest tumor (ROHHHAD[NET]) is a rare and potentially fatal disease. No specific diagnostic biomarker is currently available, making prompt diagnosis challenging. Since its first definition in 2007, a complete clinical analysis leading to specific diagnosis and follow-up recommendations is still missing. OBJECTIVE The purpose of this work is to describe the clinical timeline of symptoms of ROHHAD(NET) and propose recommendations for diagnosis and follow-up. DESIGN We conducted a systematic review of all ROHHAD(NET) case studies and report a new ROHHAD patient with early diagnosis and multidisciplinary care. METHODS All the articles that meet the definition of ROHHAD(NET) and provide chronological clinical data were reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis individual patient data guidelines. The data were grouped into 7 categories: hypothalamic dysfunction, autonomic dysregulation, hypoventilation, NET, psychiatric symptoms, other clinical manifestations, and outcome. RESULTS Forty-three individual patient data descriptions were analyzed. The timeline of the disease shows rapid-onset obesity followed shortly by hypothalamic dysfunction. Dysautonomia was reported at a median age of 4.95 years and hypoventilation at 5.33 years, or 2.2 years after the initial obesity. A NET was reported in 56% of the patients, and 70% of these tumors were diagnosed within 2 years after initial weight gain. CONCLUSION Because early diagnosis improves the clinical management and the prognosis in ROHHAD(NET), this diagnosis should be considered for any child with rapid and early obesity. We propose guidance for systematic follow-up and advise multidisciplinary management with the aim of improving prognosis and life expectancy.

Abstract
The paucity of epidemiological data regarding diabetes complications in Brazil motivated us to evaluate the prevalence rates of distal symmetric polyneuropathy (DSP) and of cardiovascular autonomic neuropathy (CAN) in individuals with type 2 diabetes (T2D) followed in a primary care unit. A total of 551 individuals (59.3% women, 65 years old; diabetes duration of 10 years; HbA1c of 7.2%, medians) were included in this cross-sectional study. DSP was diagnosed by sum of the Neuropathy Symptoms Score (NSS) and Modified Neuropathy Disability Score (NDS) and by the Semmes-Weinstein monofilament. CAN was diagnosed by cardiovascular autonomic reflex tests combined with spectral analysis of heart rate variability. The prevalence rates of DSP were 6.3% and 14.3%, as evaluated by the sum of NSS and NDS and by the Semmes-Weinstein monofilament, respectively. Those with DSP diagnosed by monofilament presented longer diabetes duration, worse glycemic control and a higher stature. The prevalence rates of incipient and definitive CAN were 12.5% and 10%, respectively. Individuals with definitive CAN presented a higher frequency of hypercholesterolemia and of arterial hypertension. The higher prevalence rate of DSP with the use of the monofilament suggests that it may be a more appropriate tool to diagnose DSP in the primary care setting in Brazil.
