Abstract Objectives Visual cognitive performance (VCP) is an important factor in high-speed interactions with the environment such as sports or driving, however, the testing, training and determination of factors that influence this ability has been elusive. Iron intake from heme sources has been shown to prevent altered metabolic processes, reductions in protein and neurotransmitter synthesis, and cognitive abilities and neural functions. The purpose of this study is to determine whether chronic dietary iron intake explain the large difference in VCP and training responses between healthy individuals. Methods Men and women age 18–35 completed 15 visual cognitive training sessions (Neurotracker) in 10 visits to the laboratory. On the days of training, all food intake was documented (Nutribase) along with measures of body composition, blood pressure, hydration status, sleep patterns, and recent exercise. Mean nutritional intakes were calculated for the 10 days of food records. Total daily intakes of iron were also calculated for each of the 10 days of food records. Results Iron intake was significantly associated to VCP (P < 0.001) in women (N = 52) but not men (N = 36). VCP improved progressively with dietary iron intake in women from low (iron: 8.2 ± 1.2 mg/day, VCP: 1.38 ± 0.22, N = 24), medium (iron: 13.4 ± 1.3 mg/day, VCP = 1.59 ± 0.38, N = 21) to high (20.9 ± 3.8 mg/day, VCP = 1.86 ± 0.33, N = 7) in which all groups were all significantly different from each other (P < 0.05). Conclusions These results suggest that intakes of iron at or above the RDA may be essential to optimize VCP. Funding Sources National Cattlemen's Beef Association.

Abstract Objectives Visual cognitive performance (VCP) is an important factor in high-speed interactions with the environment such as sports or driving, however, the testing, training and determination of factors that influence this ability are scarce. The purpose of the Nutrition, Vision and Cognition in Sport Studies (IONSport) is to determine the nutritional factors that explain large variance in VCP and training responses. The objective of this study is to determine if daily beef or vegetable protein consumption affect VCP training responses. Methods Thirty-seven women (age 18–35 years) were randomized to either one serving of beef (90% lean ground sirloin, 3 oz) or one serving of vegetable protein (Morningstar prime veggie burgers, 3 oz) per day for 30 days. These foods were equivalent in serving size, calories, protein and fat but distinct in micronutrients. At the end of the dietary intervention, they performed 15 visual cognitive training sessions (Neurotracker) in 10 visits to the laboratory. On the days of training, all food intake was documented for 18 days (Three prior to starting, five from day zero to 15 and 10 from day 15–30). Mean nutritional intakes were calculated for the 15 days of food records during the intervention. Results Both groups significantly (P < 0.001) improved VCP from baseline (1.33 ± 0.33) to the end of training (1.62 ± 0.32), however, the improvement in the beef group was significantly higher (beef Δ = 0.36, veggie Δ = 0.19). Conclusions These results suggest that 30 days of daily beef intake is associated with better improvements in VCP as compared to a vegetable protein source.

The overall purpose of the Nutrition, Vision and Cognition in Sport Studies (IONSport) is to determine the nutritional factors that explain large variance in VCP and training responses. The objective of these studies is to determine if beef associated nutrients affect VCP. Methods In the preliminary study, 52 college age women performed 15 visual cognitive training sessions (Neurotracker) in 10 visits to the laboratory (all 10 visits within 15 days). On the days of training, all food intake was documented (no intervention, no change in diet). Mean nutritional intakes were calculated for the 10 days of food records. For the RCT intervention, 80 women were randomized to either a daily beef or veggie patty and consumed 1 patty/day for 30 days. Results In the preliminary study, iron intake was significantly associated to VCP (P < 0.001) where groups of low (<10 mg/day), medium (10–20 mg/day) and high (>20 mg/day) were all significantly different from each other (P < 0.05). Cholesterol, choline, arginine and B vitamins intake were also significantly associated to VCP (P < 0.05). Preliminary analyses of the RCT to enrich these nutrients with beef indicate higher mean VCP for the beef group with significant differences in mean daily intakes of beef associated nutrients. Conclusions These results suggest that high intake of beef associated nutrients may improve VCP. Funding Sources RCT funded by National Cattleman's Beef Association.

Cognitive abilities are good predictors of safety performance in many occupations. However, this correlation has not been studied from the perspective of high-speed railway (HSR) dispatchers who play a vital role in ensuring the safety and punctuality of HSR transportation system. Therefore, studying factors affecting HSR dispatchers’ safety performance is not only of great importance in filling the theoretical gap, but also conducive to the selection and training of dispatchers, contributing to the reduction of human errors and the prevention of railway accidents. In this study, a total of 118 HSR dispatchers from a branch of China Railway were recruited to complete the tests that examined their cognitive abilities related to the dispatching job, including logical reasoning, visual multiobject tracking, working memory, task switching, and cognitive flexibility. Safety performance, including both the safety evaluation score obtained from the dispatchers’ monthly safety performance record of the Railway Bureau and the emergency disposal performance indicated by train delay time, was evaluated with a dispatch simulator. The results suggested that better abilities in visual multiobject tracking, working memory, task switching, and cognitive flexibility were correlated with higher safety evaluation score (reflecting daily safety performance) and shorter train delay time (reflecting safety and efficiency in emergency disposal). No significant correlation was found in logical reasoning. These findings support the recommendation that cognitive abilities investigated as predictors of safety performance could be useful for the selection and training of HSR dispatchers.

<p class="0abstract">Context-aware mobile applications can adapt to different mobile, user and application contexts. Mobile cloud computing has been integrated with those applications to benefit from the cloud resources and make up for the limited mobile resources. This paper proposes such an application for the assessment and training of student visual cognitive abilities and skills that constitute an integral part of student intelligence such as the visualization ability of recognizing rotated objects. The need to ubiquitously and continuously deliver exercises relevant to a specific visual cognitive ability or skill according to the student proficiency and context has stimulated proposing the context-aware cloud-based MObile application for assessment and training of visual Cognitive Abilities (MOCA) presented in this paper. Integrating cloud computing with MOCA allows creating an extendible repository on the cloud and saving the relatively limited mobile resources that would be consumed by visual material. MOCA can be used in applications that are based on such cognitive abilities such as teaching visual science concepts and the visual classification and diagnosis of medical images. Two prototype mobile applications have been developed based on MOCA for visualization ability and for visual classification of science concepts. Empirical evaluation has shown the effectiveness of MOCA in training the students and the satisfaction of the students and teachers with its capabilities. MOCA is also a framework for building systems for other types of cognitive abilities.</p>

AbstractParenting behavior has a vital role in the development of the brain and cognitive abilities of offspring throughout childhood and adolescence. While positive and aggressive parenting behavior have been suggested to impact neurobiology in the form of abnormal brain activation in adolescents, little work has investigated the links between parenting behavior and the neurobiological correlates of cognitive performance during this age period. In the current longitudinal fMRI study, associations between parenting behaviors and cognitive performance and brain activation across mid- and late-adolescence were assessed. Observed measures of maternal aggressive and positive behavior were recorded in early adolescence (12 years) and correlated with fMRI activation and in-scanner behavioral scores on the multi-source interference task (MSIT) during mid- (16 years; 95 participants) and late-adolescence (19 years; 75 participants). There was a significant reduction in inhibitory-control-related brain activation in posterior parietal and cingulate cortices as participants transitioned from mid- to late-adolescence. Positive maternal behavior in early-adolescence was associated with lower activation in the left parietal and DLPFC during the MSIT in mid-adolescence, whereas maternal aggressive behavior was associated with longer reaction time to incongruent trials in late-adolescence. The study supports the notion that maternal behavior may influence subsequent neurocognitive development during adolescence.

Marketing Information

In its recent statement on iron,1 the Committee on Nutrition emphasized the value of iron-fortified, proprietary milk formulas for the prevention of iron-deficiency anemia of infancy. Despite this recommendation, the most recent marketing information available to the Committee shows that more than 70% of the proprietary formulas currently prescribed by physicians do not contain added iron. The reasons for continuing routine use of formulas not fortified with iron are not entirely clear. One reason may be that some physicians still believe iron additives increase the incidence of feeding problems or gastrointestinal disturbances. There is no documented evidence that this is a significant problem. The Committee strongly recommends when proprietary formulas are prescribed that iron-supplemented formulas be used routinely as the standard–that is, that this be the rule rather than the exception. There seems to be little justification for continued general use of proprietary formulas not fortified with iron. The Committee is fully aware that only a small percentage of American infants are fed proprietary formulas after 6 months of age. Fluid whole milk (available in bottle or carton ) or evaporated milk, both of which contain only trace amounts of iron, are substituted at the time of greatest iron need and highest prevalence of iron-deficiency anemia. The infant's diet is usually deficient in iron, unless other foods are carefully selected to insure adequate iron intake. Since the major dietary component during infancy is milk, two courses of action should be taken: (1) Pediatricians and other health professionals should engage in a program of public education to convince American mothers to provide their infants with a source of dietary iron.

Determinations of blood volume, total red cell volume, plasma and red cell iron turnover rates, and red cell survival were performed in seven dogs prior to and subsequent to radioiodine destruction of the thyroid gland. Anemia developed slowly in all animals as a result of a diminished rate of red cell synthesis. Erythrocyte survival was unaffected by thyroid ablation. Serum iron concentration decreased in five animals despite the apparent adequacy of dietary iron intake and the absence of detectable external loss. In two animals, parenteral administration of iron failed to correct the anemia. Vitamin B12 was ineffective in correcting the anemia or in producing a reticulocyte response in two other animals.

The causal relationship between serum ferritin and metabolic syndrome (MetS) remains inconclusive. Dietary iron intake increases serum ferritin. The objective of this study was to evaluate associations of total, heme, and nonheme dietary iron intake with MetS and its components in men and women in metropolitan China. Data from 3099 participants in the Shanghai Diet and Health Survey (SDHS) obtained during 2012–2013 were included in this analysis. Dietary intake was assessed by 24-h diet records from 3 consecutive days. Multivariate generalized linear mixed models were used to evaluate the associations of dietary iron intake with MetS and its components. After adjustment for potential confounders as age, sex, income, physical exercise, smoking status, alcohol use, and energy intake, a positive trend was observed across quartiles of total iron intake and risk of MetS (p for trend = 0.022). Compared with the lowest quartile of total iron intake (<12.72 mg/day), the highest quartile (≥21.88 mg/day) had an odds ratio (95% confidence interval), OR (95% CI), of 1.59 (1.15,2.20). In addition, the highest quartile of nonheme iron intake (≥20.10 mg/day) had a 1.44-fold higher risk of MetS compared with the lowest quartile (<11.62 mg/day), and higher risks of MetS components were associated with the third quartiles of total and nonheme iron intake. There was no association between heme iron intake and risk of MetS (p for trend = 0.895). Associations for total and nonheme iron intake with MetS risk were found in men but not in women. Total and nonheme dietary iron intake was found to be positively associated with MetS and its components in the adult population in metropolitan China. This research also revealed a gender difference in the association between dietary iron intake and MetS.
