Technical Aspects of Videotaping
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
The videographer should research which camera will fulfill the desired quality at an acceptable cost. The use of a stable tripod is recommended to reduce jitter, which is inevitable in handheld recording devices. A small detachable microphone is essential in recording movement disorder patients because this can greatly enhance the speech comprehension and reduce background noise without interfering with the patient’s movements. High-definition (HD) video is now available on most cameras and provides reasonably manageable file sizes of acceptable quality, which are easily edited. Videos can be saved or converted into many formats or edited by one of many editing programs. Editing is now relatively simple and can be learned using online tutoring videos or associated instructions for each program. Given the confidential nature of patient videos and their inherent value in education, patient care, and research, security and reliability of file storage is of extreme importance.
Environment for Taping
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Environmental conditions are crucial to producing a good video. A designated area for videotaping is necessary to consistently produce consistently high-quality standardized videos. For those who evaluate movement disorder patients frequently, a special video room dedicated to filming patients is ideal, with controlled conditions for quality background and lighting. An identified hallway or space where patients can walk a longer distance is also needed. Key video room equipment and technical equipment kept in the video room will assure all resources are needed for adequate videotaping, including props, furniture, and writing tools. We provide tips that will prevent some of the common mistakes observed on poor-quality videotapes.
Consent Issues for Videotaping
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Ideally, all patients with movement disorders would sign a consent for videotaping, even if the taping is for clinical care only. It is necessary to explain the rationale for the video recording to the patient, and to obtain a written consent form from the patient or their legal representative. It is important to collect identifying information to link to the video record, for accurate storage and retrieval purposes. Guidelines detailed earlier pertaining to HIPAA should be followed in using videotapes for research use. However, additional regulations and consents need to be addressed when videotapes are specifically used for research, education or publication.
Editing for Publication
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Some publications, including medical journals, will accept videos with manuscript or document submission. For most journals, the video is a supplement to the article and only accessible online, although some journals (such as the Movement Disorders Journal) send periodic DVDs to journal subscribers or maintain an online searchable database of videos. In contrast to the more comprehensive protocols, videos submitted for publication need to be short and to the point in order to meet the requirements of limited data space and precision. However, if one has followed the comprehensive protocols, finding a few portions of the examination that best represent the patient and their movement disorders should be easy.
Tremor
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Tremor is the most common movement disorder. It is a rhythmic oscillation that can occur at rest or with action. It can be seen in isolation or in the setting of other movement disorders. The tremor video protocol focuses on features of the most common presentation of tremor (essential tremor). Tasks in the protocol illustrate postural sustention and various actions (spiral drawing and water pouring). Taping of more unusual tremors is addressed, such as orthostatic and palatal tremor. Although rest tremor is included in this protocol, since rest tremor is nearly always associated with parkinsonism, parkinsonism patients are best best filmed with other protocols.
Chorea
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Chorea is defined as involuntary, irregular, arrhythmic, nonpatterned, purposeless movements that flow randomly from one body part to the other. Patients with chorea commonly demonstrate other features including motor impersistence (inability to sustain voluntary muscle contraction), exaggerated gestures, which are caused by superimposition of chorea onto voluntary movements, and an irregular, dancelike gait. Due to the unpredictable nature of chorea, videotaping should show different areas of the body under various conditions. Abnormalities seen in Huntington disease, such as eye movements and tests of executive function are also included in the chorea protocol.
Myoclonus
Authors: Barton Brandon R. , Hall Deborah A. 
Published: November 2015

Abstract
Myoclonus is defined as a sudden, brief, “shocklike,” involuntary movement. It has a broad differential diagnosis. It can be further divided into positive myoclonus, which is active contraction of the muscle, and negative myoclonus or asterixis, defined as sudden loss of tone in the muscle. It must be distinguished from other hyperkinetic movements such as tics, chorea, tremor, and dystonia, which can all also have fast, jerky movements. The goal of videotaping is to capture the myoclonus in all the possible positions of occurrence and localize them to particular body regions. This is done by first observing at rest, then providing multiple types of stimulus including startle, touch, reflex elicitation, and finally provocation of myoclonus by voluntary activation of each body region.
Natural Infection of Soybean with Soybean vein necrosis-associated virus Grown under Greenhouse Conditions: An Accidental Observation
Authors: Hajimorad M. R. , Halter M. C. , Mengistu A. 
Published: November 2015

These data demonstrate occurrence of natural infection of SVNaV in soybean under greenhouse conditions during winter in the absence of field-grown soybeans or any infected host plant within the greenhouse. The observations point to the likelihood that overwintering viruliferous adult thrips may have the potential to serve as a local source of SVNaV; however, the epidemiological significance needs to be determined.

Corporate dividend policy in practice: the views of Nigerian financial managers
Authors: Ozo Friday Kennedy , Arun Thankom Gopinath , Kostov Philip , Uzonwanne Godfrey Chidozie 
Published: November 2015

Purpose– The purpose of this paper is to provide an additional insight into the dividend puzzle by investigating the field practice of dividend policy in an emerging market such as Nigeria. It also aims to contribute to the literature on industry-related dividend effect by examining whether managerial views on dividend policy vary between financial and non-financial firms.Design/methodology/approach– The study employs semi-structured interviews with the financial managers of 21 Nigerian listed firms. The interviewees were divided into two broad groups of financial vs non-financial firms based on the industry classification of the firms.Findings– The findings suggest that, despite differences in institutional environment, the dividend-setting process in Nigerian companies is similar in many extents to those in the USA and other developed markets. Nigerian companies exhibit dividend conservatism and typically focus on current earnings, stability of earnings and availability of cash when determining their current dividend levels. However, unlike in prior studies, the interviewees suggest that their companies do not have a target payout ratio; instead, they target the dividend per share when determining the disbursement level. Nevertheless, views regarding these issues vary significantly between financial and non-financial firms.Originality/value– This paper adds to the extant literature that has examined the behavioural aspects of dividend policy using interviews, especially in the context of less-developed markets such as Nigeria. The study also updates and extends prior evidence on an industry-related effect on managerial perceptions of dividend policy.
Corporate social responsibility, stock salience, and the asymmetric market impact of consumer sentiment news on Spanish firms
Authors: Oliver Barry , Pérez-Gladish Blanca , Méndez-Rodríguez Paz 
Published: November 2015

Purpose– The purpose of this paper is to identify whether the Spanish stock market experiences a negativity effect on the announcement of Spanish consumer sentiment information and if firms that are signatory to the UN Global Compact on corporate social responsibility are relatively more salient in the minds of investors.Design/methodology/approach– The authors use consumer sentiment announcements to show how the negativity effects on the Spanish stock market are significantly influenced by how salient the stock is in the minds of investors. If a firm’s stock exhibits negativity effects on the release of consumer sentiment information then this stock is salient to investors. If firms who are signatory to the UN Global Compact exhibit significant negativity effects, it could be concluded that these stocks are salient, particularly if firms that are not signatory to the Global Compact do not exhibit a similar negativity effect.Findings– The IBEX35 index experiences significant negativity effects upon the release of Spanish consumer sentiment announcements. This is similar to that reported in other countries, notably Australia and the USA. Using the constituent firms in the IBEX35 index, the authors find that those firms that are signatory to the UN Global Compact are significantly more likely to experience negativity effects upon the release of Spanish consumer sentiment information than if they are not signatory to the Global Compact. This indicates that firms that are part of the UN Global Compact are more salient to investors.Research limitations/implications– Available published Spanish data on consumer sentiment.Practical implications– Little is understood of the impact that consumer sentiment announcements have on stock prices. Studies in USA and Australia have identified significant negativity effects in stock markets when consumer sentiment information is released. This research has found that a psychological negativity bias occurs in firms that are salient to investors. Salience has been found to be important in asset pricing.Originality/value– This paper tries to find out which companies are more likely to sign the UN Global Compact. These companies are more sensitive to consumer sentiment, because they depend on the everyday decisions of the consumers. The more the companies depend on consumers, the more they care about them. And, when the consumer sentiment goes down, they are more affected by this sentiment. These firms are also more worried about the long term. They are not only thinking about the profits in the short term but also about maintaining the generation of profits in the long term.

Published: November 2015

AbstractWith this work we addressed some molecular systematic issues within the Mugil cephalus species complex. Particular attention was paid to the debated situations of: (i) Mugil liza, occurring in partial sympatry with Mugil cephalus in the northwestern Atlantic, and (ii) Mugil platanus, considered by some authors a synonymy of the former species and distributed in the southwestern Atlantic. We sequenced 79 individuals of a 465‐bp portion of the mitochondrial control region (CR) from 8 western Atlantic and 2 Mediterranean localities. In addition, all CR sequences available from GenBank for the studied taxa were added to our dataset, for a total of 323 individuals. Overall, 229 haplotypes corresponding to 8 divergent monophyletic lineages were detected. Results of phylogenetic analyses were consistent with the occurrence of past speciation events producing the observed lineages. Of these lineages, 7 correspond to cryptic species and one is constituted by M. liza and M. platanus. As a matter of fact, these 2 taxa constitute a single lineage within the M. cephalus species complex. However, individuals of M. liza/M. platanus lineage analyzed by means of the 18 mitochondrial markers available in GenBank exhibited a degree of genetic diversity consistent with highly divergent populations. Of the 8 lineages detected, the Mediterraean one (type locality) corresponds to M. cephalus; the lineage M. liza/M. platanus should be named M. liza, under the priority principle, and the left 6 lineages need formal description.

AbstractThe main metabolism pathway of tryptophan is protein formation, but it can also be metabolized into serotonin and kynurenine. Indoleamine 2,3‐dioxygenase (IDO) is the enzyme that catalyzes the degradation of tryptophan into kynurenine. Mastocytosis is a heterogeneous disease characterized by mast cell accumulation in various tissues with 57% of patients having gastrointestinal involvement. We studied tryptophan metabolism in mastocytosis patients displaying or not gastrointestinal features and healthy subjects (n = 26 in each group). Mastocytosis patients with digestive symptoms displayed significantly increased kynurenine level and IDO activity as compared to healthy controls and mastocytosis patients without digestive symptoms. This could be linked to mast cell‐mediated digestive inflammation among patients with mastocytosis. This work is the first focusing on kynurenine pathway in a mast cell disease and could help to understand the pathogenesis of digestive features in mastocytosis as well as in other mast cell‐mediated diseases.

BackgroundWe aimed to examine microvolt T wave alternans (MTWA) in 24‐hour Holter electrocardiography (ECG) of children with repaired tetralogy of Fallot (TOF) to assess associations of MTWA with ventricular arrhythmias, ECG parameters, and echocardiographic findings.MethodsHolter ECG records and archive files of 56 repaired TOF patients (62.5% male) who were analyzed retrospectively. Subjects’ ECG parameters and MTWA values were compared with age–sex‐matched control group. T wave changes were analyzed by time‐domain‐modified moving average method from the three channels of 24‐hour Holter ECG.ResultsMean age was 123.4 ± 48.3 months. Median MTWA value was 55.5 μV in the control group, whereas 95.5 μV in patients group (P < 0.001). A significant weak positive correlation was found between the presence of ventricular extrasystoles and tricuspid regurgitation. There was no correlation between ECG parameters, echocardiographic findings, and MTWA.ConclusionsMTWA was increased in children with repaired TOF as reported before. To our knowledge, this is the first study analyzing MTWA with 24‐hour Holter ECG in repaired TOF patients.

Published: November 2015

BackgroundThe cause of ischemic stroke or transient ischemic attack (TIA) remains unclear after initial cardiac monitoring in approximately one‐third of patients. Randomized controlled trials (RCTs) showed that the prolonged cardiac monitoring of patients with cryptogenic stroke or TIA increased detection of atrial fibrillation (AF). We aimed to perform a meta‐analysis of all RCTs that evaluated the prolonged monitoring ≥7 days in patients with cryptogenic stroke or TIA.MethodsWe searched PubMed, EMBASE, Cochrane CENTRAL, and relevant references for RCTs without language restriction (inception through December 2014) and performed meta‐analysis using random effects model. Detection of AF, use of anticoagulation at follow‐up, recurrent stroke or TIA, and mortality were major outcomes.ResultsFour RCTs with 1149 total patients were included in the meta‐analysis. Prolonged cardiac monitoring ≥7 days compared to shorter cardiac monitoring of ≤48 hours duration increased the detection of AF (≥30 seconds duration) in patients after cryptogenic stroke or TIA (13.8% vs. 2.5%; odds ratio [OR], 6.4; 95% confidence interval [CI], 3.50–11.73; P < 0.00001; I2, 0%]. It also increased the odds of AF detection of any duration (22.6% vs. 5.2%; 5.68[3.3–9.77]; P < 0.00001; I2, 0%). The patients who underwent prolonged monitoring were more likely to be on anticoagulation at follow‐up (2.21[1.52–3.21]; P < 0.0001; I2, 0%). No differences in recurrent stroke or TIA (0.78[0.40–1.55]; P = 0.48; I2, 0%) and mortality (1.33[0.29–6.00]; P = 0.71; I2, 0%] were observed between two strategies.ConclusionProlonged cardiac monitoring improves detection of atrial fibrillation and anti‐coagulation use after cryptogenic stroke or TIA and therefore should be considered instead of shorter duration of cardiac monitoring.
Positive Effects of the Reversion of Depression on the Sympathovagal Balance after Telerehabilitation in Heart Failure Patients

Published: November 2015

BackgroundAutonomic nervous system (ANS) dysfunction appears in the course of both chronic heart failure (CHF) and depression. Comprehensive cardiac rehabilitation (CCR), apart from improving physical capacity, can reduce depressive symptoms and leads to the restoration of ANS function among CHF patients.The purpose was to evaluate the influence of the reversion of depression (measured by Beck Depression Inventory [BDI] score, cut point <10) and the physical capacity improvement (measured by peak oxygen consumption [peak VO2; ml/kg per minute]) on the sympathovagal balance (measured by low/high frequency ratio [LF/HF]) after CCR in CHF patients.MethodsThe study group comprised 111 CHF patients (New York Heart Association II–III; left ventricular ejection fraction ≤ 40%). Patients were randomized (2:1) to 8‐week CCR based on Nordic walking training (five times weekly) at 40–70% of maximal heart rate, training group (TG) n = 77, or to control group (CG) n = 34. The effectiveness of CCR was assessed by changes—delta (Δ) in LF/HF, BDI score, and peak VO2, as a result of comparing these parameters from the beginning and the end of the program.ResultsEventually, 46 patients in TG and 23 patients in CG were eligible for simultaneous ANS and psychological status analysis. Only in TG the LF/HF decreased 2.06 ± 1.14 versus 1.19 ± 0.80 (P < 0.0001) and peak VO2 increased 16.83 ± 3.72 versus 19.14 ± 4.20 ml/kg per minute (P < 0.0001). Favorable results in CG were not observed. The differences between TG and CG were significant: Δpeak VO2 (P < 0.0001); ΔLF/HF (P = 0.0001). Depressive symptoms were substantially reduced in both groups (TG, P = 0.0006; CG, P = 0.0490). Nevertheless, the greatest improvement of sympathovagal balance was observed in patients whose depression was reversed, thanks to the CCR in comparison to other patients from TG and the entire CG.ConclusionPositive effect of the sympatho‐parasympathetic balance obtained during the home CCR based on Nordic walking training results from the additive effects of the reversion of depression and physical capacity improvement in CHF patients.

BackgroundIdentifying infarct‐related artery (IRA) in patients with inferior ST elevation myocardial infarction (STEMI) has prognostic and therapeutic benefits.ObjectivesTo differentiate IRA and the location of culprit lesion in inferior STEMI, using ST segment changes in lead aVR.MethodsST segment changes in lead aVR were recorded in 150 patients, admitted with first inferior STEMI. The association of IRA and the location of culprit lesion with ST segment changes in aVR were investigated.ResultsST elevation ≥ 0.5 mm in lead aVR was present in 17 patients (11.3%), ST depression ≥ 0.5 mm in 74 patients (49.3%) and 59 patients (39.3%) did not have significant ST segment changes. Right coronary artery (RCA) was the IRA in 117 patients (78%) and left circumflex artery (LCX) in 33 patients (22%). Prevalence of RCA involvement as the IRA was different in three study groups (94.1% in ST elevation group, 83.1% in isoelectric group and 70.3% in ST depression group, P = 0.049). Presence of ST elevation had a sensitivity and specificity of 13.68 % and 96.97%, for detecting RCA lesions, respectively. ST depression had 66.67% sensitivity and 55.56% specificity for identifying LCX lesions. Clinical complications were low in our study with no significant difference among patients of three groups.ConclusionsPresence of ST elevation is highly suggestive of RCA lesions versus LCX lesions, whereas absence of ST elevation cannot rule out RCA lesions. Presence of ST depression has a moderate sensitivity and specificity for LCX lesions.
Total Mortality, Major Adverse Cardiac Events, and Echocardiographic‐Derived Cardiac Parameters with Fragmented QRS Complex
Authors: Gong Bojun , Li Zicheng 
Published: November 2015

BackgroundFragmented QRS complex (fQRS), an easily evaluated noninvasive electrocardiographic parameter, is associated with worse outcomes in patients with several cardiovascular conditions. The presence of fQRS on ECG may be an indicator of myocardial damage in patients with coronary artery disease (CAD). In this article, we performed a meta‐analysis in order to characterize the presence of fQRS on ECG in patients with CAD.MethodsWe searched English‐language randomized controlled trials involving fQRS on ECG in patients with CAD (n = 3279 patients, 12 trials). Two reviewers independently extracted data. Data on LVEF, LVESD, LVEDD, LVESV, LVEDV, total mortality, stroke, and MACE were collected. fQRS was performed a comparison with non‐fQRS, calculating pooled relatives risk (RRs) and weighted mean difference (WMD), and associated 95% confidence intervals (CIs).ResultsfQRS was associated with significant increased WMD of LVEDD (WMD, 2.26; 95%CI, 0.92 to 0.36, P = 0.0009), LVESD (WMD, 2.71; 95%CI, 1.23 to 4.19, P = 0.0003), LVEDV (WMD, 31.37; 95%CI, 24.82 to 37.92, P < 0.00001), and LVESV (WMD, 28.45; 95%CI, 22.92 to 33.98, P < 0.00001). As compared to non‐fQRS, fQRS increased risk of total mortality (RR, 3.09; 95%CI, 1.76 to 5.44, P < 0.0001) and MACE (RR, 2.85; 95%CI, 1.98 to 4.09, P < 0.00001) in patients with CAD. However, a decreased trend was observed for LVEF (WMD, –3.59; 95%CI, –7.05 to –0.12, P = 0.04). For the incidence of stoke, there was no difference between fQRS and non‐fQRS group.ConclusionsOur findings indicate that fQRS is a valuable factor to predict total mortality and MACE in patients with CAD.
