“…Although the former association was also reported in some earlier studies (52)(53)(54), the causal link between visual defects and traffic crashes, as well as the need to change current visual standards for driving, are still an open debate (52,(55)(56)(57). With regard to limb disabilities, the wide range of variability in the specific nature of the handicap makes it difficult to offer a more specific analysis of our finding, which is in agreement with the association reported by Marottoli et al between foot abnormalities and risk of being involved in a traffic crash (58).…”

PURPOSE:To assess the strength of association of main driver-dependent risk factors with the risk of causing a collision between vehicles in Spain, from 1990 to 1999. METHODS:The data for this paired-by-collision, case-control study were obtained from the Spanish Dirección General de Tráfico traffic crash database. The study included all 220,284 collisions involving two or more vehicles with four or more wheels, in which only one of the drivers involved committed an infraction. Infractor drivers comprised the case group; noninfractor drivers involved in the same collision were their corresponding paired controls. RESULTS: All driver-dependent factors were associated with the risk of causing a collision. The highest adjusted odds ratio estimates were obtained for sleepiness (64.35; CI, inappropriate speed (28.33; CI,, and driving under the influence of alcohol with a positive breath test (22.32; CI,). An increase in the number of years in possession of a driving license showed a protective effect, albeit the strength of the effect decreased as age increased. CONCLUSIONS: Our results emphasize the urgent need to implement strategies aimed mainly at controlling speeding, sleepiness, and alcohol consumption before driving-the main driver-dependent risk factors for causing a vehicle collision.

Minimal hepatic encephalopathy (MHE) is the mildest form of the spectrum of neurocognitive impairment in cirrhosis. It is a frequent occurrence in patients of cirrhosis and is detectable only by specialized neurocognitive testing. MHE is a clinically significant disorder which impairs daily functioning, driving performance, work capability and learning ability. It also predisposes to the development of overt hepatic encephalopathy, increased falls and increased mortality. This results in impaired quality of life for the patient as well as significant social and economic burden for health providers and care givers. Early detection and treatment of MHE with ammonia lowering therapy can reverse MHE and improve quality of life. ( J CLIN EXP HEPATOL 2015;5:S42-S48) H epatic encephalopathy (HE) is a neurocognitive disorder in which brain function is impaired and is associated with both acute and chronic liver dysfunction. 1 It is a major complication that develops in some form and at some stage in a majority of patients with liver cirrhosis. Minimal HE (MHE) is the mildest form of spectrum of HE which is characterized by subtle cognitive and psychomotor deficits in the absence of recognizable clinical symptoms of HE. 2 It occurs in patients with liver dysfunction and/or portosystemic shunts. In MHE, neurocognitive abnormalities primarily affect attention, speed of information processing, executive control, motor ability and coordination in an individual. 3 In 1970, Zeegen et al 4 first described this condition when they discovered that 38% of patients who had undergone portal decompression surgery scored abnormal in Reitan trail making test (number connection test). Eight years later, the term subclinical HE 5 was introduced to describe these patients. Since then, this condition was described under various names like early HE, latent HE, subclinical HE and finally minimal HE. The latest classification combines MHE and grade 1 HE into covert HE while higher grades are classified as overt HE, thus simplifying the clinical schema so that HE can be uniformly diagnosed. 6 Covert HE means that the mental defect is not detectable by the clinician using conventional testing and is not noticeable to the patient. However, it is significant because these patients usually have neuropsychiatric and neurophysiological abnormalities on advanced testing which are not enough to cause disorientation or asterixis. MHE is regarded as a preclinical stage of HE and ammonia and systemic inflammation plays an important role in its pathogenesis similar to HE. Ammonia lowering therapies were used in the treatment of MHE and found to be effective.MHE is clinically significant as it impairs daily functioning, health related quality of life (HRQOL) and driving skills, predicts the development of overt HE and is associated with poor survival. 7-11 Overt HE develops in >50% of MHE patients within three years. 10 These patients pose a significant burden to their care givers depending on the severity of cognitive dysfunction. 2,12 Considering all ...

“…Though driving a vehicle is shown to be a highly visual dependent task, a number of studies have shown that there is no clear relationship between visual acuity and driving performance (Ball et al, 1993;Decina & Staplin, 1993;Gresset & Meyer, 1994;Hills, 1980;Ivers et al, 1999; Johansson et al, 1996;Marottoli et al, 1994;McCloskey et al, 1994;Owsley et al, 1998;Owsley et al, 1991;Shinar & Schieber, 1991). However, some other tasks such as reading road signs and avoiding obstacles in the roadway, are found to be affected by visual acuity loss (Higgins et al, 1998).…”

and Related Visual Contrast Sensitivity Haruetai Mekaroonreung (ABSTRACT) This research was designed to investigate the relationship between Trait-based Individual differences (neuroticism and extraversion) and glare subjective responses as well as the actual contrast sensitivity when exposed to the same manipulated glare condition. In addition, the relationship between the glare subjective responses and actual contrast sensitivity was investigated. To examine the trait-based individual differences, the International Personality Item Pool (IPIP) was used while the subjective glare experience was examined utilizing modified glare discomfort rating scale. The visual performance was measured through the contrast sensitivity level using adjustable contrast level of the Landolt's C target. This investigation compared 36 individuals (9 high neuroticism scorers, 9 low neuroticism scorers, 9 high extraversion scorers, and 9 low extraversion scorers) on subjective discomfort glare rating responses and visual contrast sensitivity. The study is directed toward improving our understanding of influencing factors on the experience of discomfort glare, which may eventually be applied to the design of glare measurement methods, and toward training and selection of drivers and workers who may work under conditions of glare. Results indicated significant effect of extraversion trait on rating response while insignificant effect on visual related performance was found. The relationships between rating response and visual performance were also found to be quite low in this study. In conclusion, the expected model was supported but only on the extraversion trait. RationaleFeelings of discomfort glare have been widely assessed with rating scales for various purposes, especially in the design of lighting configurations such as street lighting and visual display terminal (VDT) systems. However, consensus is lacking among researchers in terms of discomfort glare assessment methods (Gellatly and Weintraub, 1990;Lennie & Van Hemel, 2002;Olson & Sivak, 1984;Sivak & Flannagan, 1994). Although the between-subject variations in rating scores are repeatedly reported to be quite high, the subjective glare rating has been the method used for many years.Several subjective rating scales have been proposed since the 1960s (De Boer, 1967a).Among these rating scales, the 9 point De Boer scale is most often used in the field of automotive and public lighting systems (Theeuwes, 2002) while some other scales such as Visual Analog Scale (VAS) are used less frequently.As suggested by few researchers (Berman et al., 1994;Theeuwes, 2002), one underlying reason for the large variability of this subjective response could be the result of differences in the observers' trait rather than visual impairment. For example, people with dispositions related to worry or anxiety may have a perceived criterion for discomfort that is much lower than those who have dispositions that are less anxiety or worry prone. As a result, the worried people could exhibit more...
