RESUMEN

BACKGROUND AND OBJECTIVES: Previous research has shown that alcohol craving is associated with psychiatric comorbidities. However, no population studies have examined the odds of psychiatric disorders in cravers and noncravers. The purpose of this study was to investigate current prevalence rates and odds ratios of psychiatric disorders among alcohol drinkers with and without alcohol craving in a population-based sample. We also compared four craving groups (cravers with and without alcohol use disorder [AUD], noncravers with and without AUD) for psychiatric comorbidities. METHODS: The study data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). A subset of the NESARC sample (N = 22 000) who reported alcohol use during the past 12 months was included. Prevalence rates of psychiatric disorders were compared among current drinkers with alcohol craving (N = 900) and without alcohol craving (N = 21 500). RESULTS: Cravers had higher prevalence rates of current psychiatric disorders than noncravers. Even after adjustment for other psychiatric disorders including AUD, cravers had significantly higher odds of any substance use disorder (adjusted odds ratio [AOR], 9.01), any mood disorder (AOR, 1.78), any anxiety disorder (AOR, 1.86), and any personality disorder (AOR, 1.92) than noncravers. Interestingly, cravers without AUD had even higher rates of any anxiety disorder and any personality disorder than noncravers with AUD. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Alcohol craving is associated with a higher prevalence of various psychiatric disorders. These findings suggest that alcohol craving may be related to transdiagnostic features that are present across various psychiatric disorders. (Am J Addict 2021;30:34-42).

RESUMEN

BACKGROUND AND PURPOSE: Acute vestibular symptoms have a profound impact on patients' well-being. In this study, health-related quality of life (HRQoL) and functional impairment were investigated prospectively in patients with different peripheral and central vestibular disorders during the acute symptomatic stage to decipher the most relevant underlying factors. METHODS: In all, 175 patients with acute vestibular disorders were categorized as central vestibular (CV, n = 40), peripheral vestibular (PV, n = 68) and episodic vestibular disorders (EV, n = 67). All patients completed scores to quantify generic HRQoL (European Quality of Life Score Five Dimensions Five Levels, EQ-5D-5L) and disease-specific HRQoL (Dizziness Handicap Inventory, DHI). Vestibular-ocular motor signs were assessed by video-oculography, vestibular-spinal control by posturography and verticality perception by measurement of subjective visual vertical. RESULTS: Patients with PV had a poorer HRQoL compared to patients with CV and EV (EQ-5D-5L/DHI: PV, 0.53 ± 0.31/56.1 ± 19.7; CV, 0.66 ± 0.28/43.3 ± 24.0; EV, 0.75 ± 0.24/46.7 ± 21.4). After adjusting for age, gender, cardiovascular risk factors and non-vestibular brainstem/cerebellar dysfunction patients with PV persisted to have poorer generic and disease-specific HRQoL (EQ-5D-5L -0.17, DHI +11.2) than patients with CV. Horizontal spontaneous nystagmus was a highly relevant factor for subgroup differences in EQ-5D-5L and DHI, whilst vertical spontaneous nystagmus, subjective visual vertical and sway path were not. EQ-5D-5L decreased significantly with more intense horizontal subjective visual vertical in CV (rho = -0.57) and PV (rho = -0.5) but not EV (rho = -0.13). CONCLUSIONS: Patients with PV have the highest functional impairment of all patients with acute vestibular disorders. Vestibular-ocular motor disturbance in the yaw plane has more impact than vestibular-spinal or vestibular-perceptive asymmetry in the roll and pitch plane, suggesting that horizontal visual stability is the most critical for HRQoL.

RESUMEN

BACKGROUND: Alcohol-impaired driving causes a substantial proportion of motor vehicle accidents. Depression is a prevalent psychiatric disorder among drinker-drivers. Few previous studies have investigated the relationship between major depression and alcohol-impaired driving. OBJECTIVES: We investigated whether depression has a positive relationship with the probability of alcohol-impaired driving after controlling for the co-occurrence of binge drinking and alcohol dependence. METHODS: Our data consisted of drinkers aged 21-64 years from two waves of the National Epidemiologic Survey of Alcohol and Related Conditions. Cross-sectional analysis investigated whether depression is an independent risk factor for drinking-driving. Longitudinal analysis distinguished the relationship of depression onset, continuance, and recovery with changes in drinking-driving behaviors between the waves. These dual approaches allowed comparisons with previous studies. RESULTS: Major depression was a small but statistically significant predictor of changes in alcohol-impaired driving behaviors among males but not females. Binge drinking and alcohol dependence were comparatively stronger predictors. Conclusions/Importance: There is limited empirical support that treating depression reduces drinking and driving in males who do not exhibit symptoms of alcohol use disorders. For persons with co-occurring depression and alcohol use disorders, depression treatment should be part of a strategy for treating alcohol use disorders which are highly related to drinking and driving.

RESUMEN

BACKGROUND: Nonmedical use of prescription opioids (NMUPO) is an ongoing public health challenge, as NMUPO is associated with psychopathology, other drug use, and fatal overdose. These concomitant risks are greatest in those with opioid use disorder (OUD), but the development of NMUPO-related use disorder is poorly understood. The primary aim of this study was to establish factors associated with the development of and time to OUD among persons engaged in NMUPO. METHODS: Data were from wave 1 of the National Epidemiologic Study on Alcohol and Related Conditions, with 1755 participants endorsing lifetime NMUPO. Analyses used sequential design-based logistic regression for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) opioid dependence correlates, followed by Cox regression of proportional hazards for correlates (e.g., sociodemographics, age of NMUPO initiation, and psychopathology) of time to dependence in those who developed DSM-IV dependence. RESULTS: Earlier age of NMUPO initiation increased OUD odds (adjusted odds ratio [AOR] = 0.95, 95% confidence interval [CI] = 0.94-0.96) but slowed OUD development (adjusted hazard ratio [AHR] = 1.05, 95% CI = 1.04-1.06) in those who developed OUD (n = 118), after controlling for sociodemographics, psychopathology, and ages of other drug use initiation. Psychopathology and earlier other drug use initiation were associated with higher OUD odds, but only having an alcohol use disorder was associated with shorter time to OUD. CONCLUSIONS: Earlier NMUPO initiation is associated with increased odds of OUD, although those with early initiation had a slower progression to OUD. Programs that prevent early NMUPO initiation, which might lower rates of OUD, and/or identify the later initiators at highest risk for rapid OUD development could have great public health benefits.

RESUMEN

BACKGROUND AND OBJECTIVES: Separate literatures indicate that intimate partner violence (IPV), posttraumatic stress disorder (PTSD), and alcohol use are independently associated with increased risk for cigarette smoking. No previous studies have examined the co-occurrence of these problems on smoking quantity and potential gender-specific relationships. This study will address this gap in the literature. METHODS: Data from Wave 2 of the National Epidemiologic Study on Alcohol and Related Conditions (NESARC) were examined. Variables were assessed during the past year. Individuals (N = 25,604) who reported being married, dating, or involved in a romantic relationship were included. RESULTS: Among men, PTSD and alcohol use were associated with more cigarettes smoked per day. Among women, PTSD, alcohol use, and IPV victimization were associated with more cigarettes smoked per day. Women who experienced IPV victimization smoked approximately three additional cigarettes per day. DISCUSSION AND CONCLUSIONS: IPV victimization, PTSD, and alcohol use were associated with cigarettes smoked among women, while IPV experiences were not associated with smoking risk among men. SCIENTIFIC SIGNIFICANCE: These findings represent an important contribution to the existing literature in that it elucidates the compounding relationship between a common and complex comorbidity and cigarette smoking. Findings indicate a critical need to implement routine smoking screening and intervention in venues where intimate partner violence is commonly encountered, such as advocacy and substance use treatment settings.

RESUMEN

BACKGROUND AND OBJECTIVES: Pathological and problem gambling may be common yet frequently undetected conditions in substance use treatment. This paper reports findings on the prevalence of gambling comorbidities in these clinical contexts that are generalizable across regions and settings. It indicates the implications of such conditions for treatment of substance use problems. METHODS: A U.S. representative sample of n = 402 patients reporting past-year treatment for substance use problems was derived from wave 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Weighted prevalence estimates were produced and regression analyses used to examine correlates of gambling symptoms. RESULTS: Rates of lifetime pathological gambling (5+ DSM-IV symptoms) and problem gambling (3+ DSM-IV symptoms) were 4.3% (s.e. = 1.3%) and 7.2% (s.e. = 1.6%), respectively. Lifetime gambling symptoms were associated with Axis II disorders, but no Axis I diagnoses. There was limited evidence of associations with substance usage, mental or physical health and medical utilization. There were associations with financial crises and relationship breakdown, during and after treatment. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Gambling problems are elevated in substance use treatment but may be less common than previously thought; when considered nationally and across clinical settings. They may have modest associations with clinical characteristics given high levels of psychiatric severity that characterise treatment seeking samples overall. Notwithstanding, the results suggest that gambling comorbidities should be standard considerations in substance use treatment. They may signal complex conditions characterised by pervasive underlying psychopathology, and psychosocial difficulties that accumulate over time.

RESUMEN

OBJECTIVES: In idiopathic normal pressure hydrocephalus (NPH) ventriculoperitoneal (VP) shunt insertion is the method of choice to improve cardinal symptoms such as gait disturbance, urge incontinence and/or dementia. With reduced compliance, the brain of the elderly is prone for overdrainage complications. This was especially true with the use of differential pressure valve implantation. The present study compares clinical outcome and complication rates after VP shunt insertion with differential pressure valves in the early years and gravitational valves since 2005. METHODS: The authors reviewed patients treated at our institution for NPH since 1995. Differential pressure valves were solely used in the initial years, while the treatment regimen changed to gravitational valves in 2005. Clinical improvement/surgical success rates as well as complications were compared between the two groups. RESULTS: Eighty-nine patients were enrolled for the present study. Mean age at the time of surgery was 73.5 ± 6.3 years. Male patients predominated with 73, compared with 16 female patients. Median follow-up time was 28 ± 26 months. Date of last follow-up was 1st October 2013. Forty-nine patients received a gravitational valve, while 40 were treated with differential pressure valves. In the gravitational group a significant improvement was observed after shunt insertion for gait disorder, cognitive impairment and urge incontinence (p < 0.0001, resp. p = 0.004), while a significant change in the differential pressure group was only seen for gait disorder (p = 0.03) but not for cognition or urinary incontinency (p > 0.05). The risk of hygroma as a sign of shunt overdrainage requiring surgical intervention was significantly higher in the differential pressure group (5 versus 0 in the gravitational group). CONCLUSIONS: Patients with NPH treated with gravitational valves in the present cohort showed a more profound improvement in their initial symptoms, including gait disorder, cognitive impairment and urinary incontinency without the risk of overdrainage complications requiring surgical intervention when compared with patients who received differential pressure valves in previous years.

RESUMEN

BACKGROUND: Slow walking with reduced body dynamics is a characteristic feature of locomotion in the elderly. Impaired mobility and falls associated with gait disorders significantly contribute to a reduced quality of life in the elderly. OBJECTIVES: A gait disorder is not an inevitable consequence of aging. This article shows that it is worth recognizing specific deficits and differentiating specific aspects in multifactorial disorders because many causes can be well treated. Also provided are the bases for clinical classification and therapeutic principles. METHODS: Review of recent literature and clinical review based on own experience and own scientific results. RESULTS: Common causes of disturbed gait in the elderly are neurological deficits, including sensory deficits (e.g. peripheral neuropathy and vestibulopathy), neurodegeneration (e.g. cerebellar ataxia and parkinsonian syndromes, cognitive impairment (e.g. degenerative dementia), degeneration of joints (e.g. coxarthrosis) and general loss of muscle mass (sarcopenia). Furthermore, a fear of falling also contributes to the gait disorder. Multimodal therapies are often necessary and the principles are presented. CONCLUSION: Identification of deficits is a prerequisite for specific therapy. As physical activity protects against cognitive impairment, reduces the risk of falling and improves overall quality of life, a structured assessment of causes for gait impairment is crucial.

RESUMEN

Organ transplant recipients (OTR) are at high risk for cutaneous squamous cell carcinomas (SCC). We aimed to define clinically meaningful patient-reported warning signals predicting the presence of invasive SCC.Patient-reported signs and symptoms of 812 consecutively biopsied skin lesions from 410 OTR were determined by questionnaire and physical examination and related to the subsequent biopsy-proven diagnoses. Receiver-operating characteristic (ROC) curve analyses were used as a measure of distinction between the predictive values of patient-reported warning signals and the occurrence of SCC. Pain was an independent predictive patient-reported warning signal for a biopsy-proven invasive SCC. The odds ratio from the fully adjusted model predicting SCC was 4.4(95% confidence interval: 2.4­8.2). Higher scores on the visual analog scale (VAS) for pain were associated witha greater likelihood for the presence of SCC compared to none or mild pain. The for scores on the VAS from 1to 3, 4 to 6 and 7 to 10 were 4.9 (2.2­10.5), 2.3 (0.96­5.5)and 16.5 (3.6­75.8), respectively. Pain is the most powerful patient-reported warning signal for invasive cutaneous SCC in OTR. Empowerment of patients by education could accelerate diagnosis and treatment of cutaneous SCC.

RESUMEN

BACKGROUND: The Medicare program provides universal access to hospital care for the elderly; however, mortality disparities may still persist in this population. The association of individual education and area income with survival and recurrence post Myocardial Infarction (MI) was assessed in a national sample. METHODS: Individual level education from the National Longitudinal Mortality Study was linked to Medicare and National Death Index records over the period of 1991-2001 to test the association of individual education and zip code tabulation area median income with survival and recurrence post-MI. Survival was partitioned into 3 periods: in-hospital, discharge to 1 year, and 1 year to 5 years and recurrence was partitioned into two periods: 28 day to 1 year, and 1 year to 5 years. RESULTS: First MIs were found in 8,043 women and 7,929 men. In women and men 66-79 years of age, less than a high school education compared with a college degree or more was associated with 1-5 year mortality in both women (HRR 1.61, 95% confidence interval 1.03-2.50) and men (HRR 1.37, 1.06-1.76). Education was also associated with 1-5 year recurrence in men (HRR 1.68, 1.18-2.41, < High School compared with college degree or more), but not women. Across the spectrum of survival and recurrence periods median zip code level income was inconsistently associated with outcomes. Associations were limited to discharge-1 year survival (RR lowest versus highest quintile 1.31, 95% confidence interval 1.03-1.67) and 28 day-1 year recurrence (RR lowest versus highest quintile 1.72, 95% confidence interval 1.14-2.57) in older men. CONCLUSIONS: Despite the Medicare entitlement program, disparities related to individual socioeconomic status remain. Additional research is needed to elucidate the barriers and mechanisms to eliminating health disparities among the elderly.

RESUMEN

In the state of Hesse (Germany) all vaccinations were administered either by the public health-care (ÖGD) or private health-care facilities and were registered by week and age group. In the following article, the benefit of the vaccination campaign will be looked at in terms of preventable consultations due to acute respiratory tract infections (AK-ARI). AK-ARI were registered with the nation-wide sentinel of the AGI. Scenarios regarding timing and age-specific coverage are modelled. The achieved timing and age distribution was compared to assumed ideal distributions, e. g., having achieved the final coverage 2 weeks before epidemic start or having applied the used vaccine exclusively for the most affected age group 5-14 years. The timing and coverage actually achieved (7% overall) prevented an estimated 1.4% or, respectively, 1.1% of the total consultation excess. With the same amount of vaccine but ideally applied at least 2 weeks -before the begin of the epidemic and exclusively to the age group of the 5- to 14-year olds, an estimated 13.9% or, respectively, 18.2% of the total excess could have been prevented. The simulated scenarios give estimations as to what benefit potentially could have been achieved during the A(H1N1)pdm09 pandemic. Both the delayed successive access to vaccine and the not ideal age distribution reduced the benefit to about 30% of the optimum. These exemplary estimates underline the importance of timeliness and valid prioritising of vaccination campaigns, although footing on just one outcome. It appears beneficial to reduce uncertainties for a solid prioritisation by, e. g., timely extended surveillance. Short-term decisions and adoptions are likely for future campaigns, e. g., due to unexpected changes in the epidemic, demanding flexibility in the application management.

RESUMEN

The use of hyaluronic acid fillers for treatment of rhytides (wrinkles) is widespread in aesthetic dermatology and is considered a safe procedure; however, complications can occur especially if the injections are carried out by an inexperienced person and/or with a lack of anatomical knowledge. The two cases presented here exemplify this problem. In conclusion, both cases demonstrate complications after uncritical injection of hyaluronic acid fillers into "risk" or "expert" regions. While the patients in these two cases recovered completely, the injection of filler substances can also lead to the risk of potentially permanent side effects, such as granuloma, necrosis with scar tissue formation and even blindness. The frequency and severity of complications often show a direct correlation with the qualification or expertise of the person treating and hence injection treatments should be performed solely by physicians.

RESUMEN

Healthy persons exhibit relatively small temporal and spatial gait variability when walking unimpeded. In contrast, patients with a sensory deficit (e.g., polyneuropathy) show an increased gait variability that depends on speed and is associated with an increased fall risk. The purpose of this study was to investigate the role of vision in gait stabilization by determining the effects of withdrawing visual information (eyes closed) on gait variability at different locomotion speeds. Ten healthy subjects (32.2 ± 7.9 years, 5 women) walked on a treadmill for 5-min periods at their preferred walking speed and at 20, 40, 70, and 80 % of maximal walking speed during the conditions of walking with eyes open (EO) and with eyes closed (EC). The coefficient of variation (CV) and fractal dimension (α) of the fluctuations in stride time, stride length, and base width were computed and analyzed. Withdrawing visual information increased the base width CV for all walking velocities (p < 0.001). The effects of absent visual information on CV and α of stride time and stride length were most pronounced during slow locomotion (p < 0.001) and declined during fast walking speeds. The results indicate that visual feedback control is used to stabilize the medio-lateral (i.e., base width) gait parameters at all speed sections. In contrast, sensory feedback control in the fore-aft direction (i.e., stride time and stride length) depends on speed. Sensory feedback contributes most to fore-aft gait stabilization during slow locomotion, whereas passive biomechanical mechanisms and an automated central pattern generation appear to control fast locomotion.

RESUMEN

Most economists believe that people would value an additional $1,000 in income more if they were poor than if rich, but if so, people should not gamble according to standard expected utility theory. Thus, economists have been challenged to explain the pervasiveness of gambling in human behavior. A recently proposed solution to this theoretical challenge (Nyman 2004; Nyman et al. in Journal of Socio-Economics 37:2492-2504, 2008) suggests that, because having to work for one's income is a fact of life in market economies, many individuals view the winnings from gambling not only as additional income, but as additional income for which one does not need to work. As a result, individuals, and especially those who are disadvantaged in the labor market, attach a utility premium to gambling winnings and gamble because of that. This utility premium would explain the pervasiveness of gambling in society, especially among the economically disadvantaged. This paper reviews the economic approaches to explaining non-pathological gambling, presents an overview of the new theory, and uses data from the National Epidemiological Survey of Alcohol and Related Conditions from 2001 to test it. The results indicate that the respondent's work characteristics explain the decision to gamble in a way that is consistent with theory.

RESUMEN

Dermatomycoses due to pets and farm animals are often a clinical and diagnostic challenge for dermatologists. A 24-year-old man presented with inflammatory skin changes on his cheeks and chin. Because of negative fungal culture and the clinical appearance of a highly inflammatory process, our first diagnosis was a bacterial pyoderma. Polymerase chain reaction (PCR) identified Arthroderma benhamiae in both the patient and his guinea pig. A. benhamiae is a zoophilic dermatophyte which belongs to the Trichophyton mentagrophytes-complex. The fungus is acquired from guinea pigs and causes highly inflammatory forms of tinea. PCR-based diagnostics are quick and simple tools to identify this pathogen, so that suitable antimycotic therapy can be initiated quickly.

RESUMEN

Migraine equivalents are the most common cause of vertigo in children and adolescents. Vertigo and balance disorders occur frequently in children during the course of otitis media, middle ear effusion and viral infections. If otitis media is associated with reduced hearing and vertigo, labyrinthitis must be considered. Craniocerebral injury is another important cause of vertigo in children. In contrast, spontaneous benign paroxysmal positional vertigo is rare among children. The isolated cases of endolymphatic hydrops that occur in children are usually secondary. Perilymph fistula can have congenital, infectious or trauma-related causes. The following characteristics are useful for differentiating between different vertiginous syndromes: type and duration of vertigo, triggering/aggravating/alleviating factors and accompanying symptoms. A neuro-ophthalmologic examination is essential to rule out central vestibular disorders.

RESUMEN

It is a widely held belief that the sole effect of muscle on bone is through mechanical loading. However, as the two tissues are intimately associated, we hypothesized that muscle myokines may have positive effects on bone. We found that factors produced by muscle will protect osteocytes from undergoing cell death induced by dexamethasone (dex), a glucocorticoid known to induce osteocyte apoptosis thereby compromising their capacity to regulate bone remodeling. Both the trypan blue exclusion assay for cell death and nuclear fragmentation assay for apoptosis were used. MLO-Y4 osteocytes, primary osteocytes, and MC3T3 osteoblastic cells were protected against dex-induced apoptosis by C2C12 myotube conditioned media (MT-CM) or by CM from ex vivo electrically stimulated, intact extensor digitorum longus (EDL) or soleus muscle derived from 4 month-old mice. C2C12 MT-CM, but not undifferentiated myoblast CM prevented dex-induced cell apoptosis and was potent down to 0.1 % CM. The CM from EDL muscle electrically stimulated tetanically at 80 Hz was more potent (10 fold) in prevention of dex-induced osteocyte death than CM from soleus muscle stimulated at the same frequency or CM from EDL stimulated at 1 Hz. This suggests that electrical stimulation increases production of factors that preserve osteocyte viability and that type II fibers are greater producers than type I fibers. The muscle factor(s) appears to protect osteocytes from cell death through activation of the Wnt/ß-catenin pathway, as MT-CM induces ß-catenin nuclear translocation and ß-catenin siRNA abrogated the positive effects of MT-CM on dex-induced apoptosis. We conclude that muscle cells naturally secrete factor(s) that preserve osteocyte viability.

RESUMEN

Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in the Western World. It belongs to the low-grade non-Hodgkin lymphomas and is characterized by clonal reproduction of mature small-cell non-functional B-lymphocytes. CLL affects men somewhat more often than women and the average age at onset is over 50 years. In addition to regional lymph node swelling, typical symptoms include hepatosplenomegaly, leukocytosis and skin disorders such as eczema and pruritus. Manifestations in the oropharynx or hypopharynx are rare but should be kept in mind in the differential diagnosis.

RESUMEN

Gait disorders are among the most common presenting symptoms in neurology. In the elderly, multiple causes of gait instability and dizziness may occur in the same subject. Relevant pathogenetic factors are sensory deficits (visual, vestibular, somatosensory), neurodegenerative processes (cortical, extrapyramidal, cerebellar), toxic factors (medication, alcohol) and anxiety (primary or as the result of falls). Reduced mobility reduces the quality of life; associated falls increase morbidity and mortality. The evaluation of aged people with the chief complaint "gait disorder" should focus on the identification of specific deficits. This is the prerequisite for reasoned therapy. Besides treatment of the underlying pathology there is a need for effective symptomatic therapy, in particular for degenerative disorders. Physical therapy with postural and locomotor training remains the basis of treatment; it can improve gait and prevent falls. So far, symptomatic drug treatment is unsatisfactory. Based on pathophysiology and uncontrolled studies, the most promising approaches are to support cholinergic neurotransmission in the midbrain and thalamus by central cholinesterase inhibitors and the regularisation of Purkinje cell function by potassium channel blockers. Brain stem nuclei which are target regions for deep brain stimulation (subthalamic and pedunculopontine nucleus) are known to be relevant for locomotor control (subthalamic and mesencephalic locomotor region). Accordingly, deep brain stimulation also affects posture and gait. The current literature on symptomatic therapy for gait disorders in the elderly is summarised.

RESUMEN

OBJECTIVE: To study the behavioral relevance of postural and ocular-motor deficits on daily activity and risk of falling in patients with bilateral vestibular hypofunction (BVH). METHODS: Thirty patients with BVH and 30 age- and gender-matched healthy controls participated in a continuous 2-week assessment of daily activities and mobility using a body-worn inertial sensor and a 6-month prospective fall risk assessment. At inclusion, patients and controls further underwent a multi-modal clinical, score- and instrument-based assessment of general health and balance status. We analyzed the relationship between clinical, lab-, and sensor-based measures and their validity to identify those patients at a risk of general, frequent, and severe falling. RESULTS: Patients exhibited impairments in daily activity in particular in terms of reduced ambulatory activity (p = 0.009). 43% of patients experienced falls (13% in controls, p = 0.008) and 70% of these patients reported recurrent falling (0% in controls, p = 0.001) during prospective assessment. Severe fall-related injuries that would require medical attention neither occurred in patients nor in controls. Classificatory models based on multi-modal clinical, lab-, and sensor-based measures of balance and mobility identified patients who fell with an accuracy of 93% and patients who recurrently fell with an accuracy of 89%. CONCLUSION: BVH is linked to particular impairments of patients' daily activities which in turn are related to patients' fall risk. Hence, off-laboratory measures of daily mobility may supplement standard clinical assessment in BVH to more adequately capture the burden of disease and to reliably identify those patients at a specific risk of falling.
