In a Spanish speaking population, detection of cognitive impairment by a general practitioner in Primary Care can be a problem, as many of the standard tests target English speaking populations. The Memory Impairment Screen (MIS-A) is a validated test using English words to detect Alzheimer’s Disease (AD) and other dementias. We have modified this test to suit a Spanish speaking population and added a new component, delayed recall. We have called our new test the Memory Impairment Screen with Delayed Recall (MIS-D). Objectives: 1) To test a Spanish version of MIS-A and MIS-D. 2) To assess the discriminative validity of MIS-D as a screening tool for the amnestic variant of Mild Cognitive Impairment (aMCI) in a group of Spanish speaking people aged 65 years old and over. Methods: A case-control study of a cohort of 739 native Spanish speaking residents of Buenos Aires aged 65 years old and over, of whom 436 were healthy controls and 303 had a diagnosis of aMCI. Measurements: Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NVP) were estimated for MIS-D and MIS-A. Results: Normative values for MIS-A and MIS-D were obtained from the control population. Both age and education significantly affected these values (p < 0.0001). Control participants showed significant differences for both modalities, MIS-A and MIS-D. The cut-off for MIS-A should be 7.5 and for MIS-D, 5.5. Comparison between control population and aMCI population using ROC curve gave a result of 5.5 in MIS-D, with 97% specificity and 76% sensitivity. Conclusion: MIS-D was positively predictive of aMCI, with 97% specificity and 76% sensitivity in a sample of Spanish speaking patients aged 65 years old and over in Buenos Aires.展开更多

The previous case in the same operating room had involved a malignant hyperthermia-susceptible patient, and charcoal filters had been placed in the breathing circuit as a precautionary measure. Because it had not been used on the evening beforehand, the circuit with filters was left in situ with a strip of tape indicating that it was clean. The woman’s anesthesiologist assumed that these filters were heat and moisture exchanger filters in an unused circuit and therefore did not remove them. Subsequently, the patient had awareness with intraoperative recall. This case highlights the potential for inadvertent use of activated charcoal filters with potentially catastrophic results. Such unintended utilization of these products likely can be minimized by improved labeling techniques.展开更多

Another 70 students waiting to undergo the colloquium were interviewed as a control group. Two parallel series of drawings depicting personal stress situations were collected and, after evaluation by three expert judges in “double-blind” conditions, led to establishing five forms of development of the graphic language from the first to second drawing, defined as follows: a) distension, with a reduction in stress indicators and increase in comfort indicators;b) explicit representation of conflict resolution;c) appearance of new elements, with persisting conflict;d) increase in stress indicators;e) invariant or equivalent repetition of the stress drawing. Results showed that students who underwent the clinical colloquium (experimental group) changed their stress drawings mainly in the direction of distension and conflict resolution, while the control group had more invariant or equivalent repetition of the stress situation (?= 62.77;p < 0.001). The events depicted in the stress drawings were divided into three categories: a) limited short-term stressful situations due to mainly external agents;b) externally induced stressful situations with intense emotional resonance;c) wide-ranging long-lasting stressful situations with great involvement of the self. The participants were divided into: a) very anxious subjects;b) averagely anxious subjects;c) not very anxious subjects, on the basis of their scores on two questionnaires: the MPI (1959) and the STAI (1970). There is a correspondence between the subjects’ level of conflict and extension of the depicted stress. This confirms the usefulness of the Stress Drawing Recall Technique in psychological counselling.展开更多

Methods: Data were obtained from the Physical Activity in Young Adults Study, a 10- year follow-up study of 12 - 16 year old adolescents. Five hundred twenty-eight young adults, mean age 24.5 (±1.0) years, completed a GPAq regarding current and past (adolescent) PA. GPAq answers were used to determine whether young adults could accurately rank their past (adolescent) PA levels relative to peers of the same age and sex. GPAq responses were compared with actual self-reported PA levels assessed by the Modifiable Activity Questionnaire for Adolescents (MAQ-A;collected during adolescence). For adolescent PA, an average of 4 years of activity from the MAQ-A 1990-1993, was used. Results: Regardless of gender, Jonckheere-Terpstra tests for trend (p < 0.0001) suggest significant linear trends across categories of PA level for the MAQ-A. Higher perceived PA tracked with greater past PA activity and lower perceived PA tracked with lower past PA activity. Conclusions: Young adults who classified themselves as more active as an adolescent were found to be relatively more active based upon self-reported activity from recall questionnaires collected during that time. These findings suggest that young adults can reasonably estimate relative PA levels during their adolescent years with GPAq. Global physical activity questions may be valid for the assessment and classification of previous PA levels.展开更多

Impairment in verbal episodic memory, and in particular in a delayed recall phase, is considered one of the early markers of progression from mild cognitive impairment (MCI) to dementia. Therefore, having cognitive screening instruments with predictive value for progression is of utmost importance. Objective: The purpose of this work is to show the predictive value, sensitivity and specificity of the Memory Impairment Screen with delayed recall (MIS-DR) to predict conversion to dementia in patients with MCI. Methods: In retrospective study 502 patients over 60 years old, evaluated in the Older Adult Functional Evaluation Unit of our hospital for cognitive complaint, were diagnosed with MCI. They were followed up to assess conversion to dementia. Results: During follow up, 144 participants developed dementia (28.6%, 95% CI 24.76 - 32.85) and the average time of progression to dementia were 23 months (SD 13.2). The cut-off point was established below 6 for MIS-DR and it showed a sensitivity of 76% (95% CI 68.77 - 77.84) and a specificity of 56% (95% CI 50.44 - 61.58), with a positive predictive value of 41% (95% CI 34.78 - 47.6) and a negative predictive value of 85% (95% CI 80.53 - 91.11) for predicting progression to dementia. Of those patients who obtained a MIS-DR score below 6, 41% developed dementia, in contrast to 14.53% of those with a score above or equal to 6, OR 4.09 (95% CI 2.64 - 6.34), p 0.00001. There were no significant differences in terms of gender, education level or vascular risk factors among patients who converted and those who did not convert to dementia. Conclusion: We believe that MIS-DR is a useful and valid test to detect episodic memory impairment and to identify patients at risk of progression to dementia.展开更多

In the study, Signal-to-Noise Ratio (SNR), recall rate and pattern complexity are defined and employed to evaluate the recall performance. The experimental results indicate that the HNN possesses significant recall capacity against the strong noise corruption, and certain restoring competence to the rotation. It is also found that combining noise with rotation does not further challenge the HNN corruption resistance capability as the noise or rotation alone does.展开更多

One hundred and five women filled in the APNI scale to assess API and ANI and were asked to listen to and recall a story presenting both positive and negative events, and provide an assessment of the character perceived happiness. Finally, they were asked to choose an ending for the story. Results showed that recall is related to the perception of happiness more than API and ANI, and that relationships occur among recall, API, ANI, and perception of happiness. A positive ending for the story was preferred. Discussion focuses on the implications of individual differences in paying attention to and recall positive and negative information.展开更多

It is unknown, however, whether aging brings about a decline of encoding and retrieval of spatial information in parallel. The present study examined spatial encoding and retrieval in male CD-1 mice at 4, 9, and 12 months of age in a complex dry-land maze. The total time to reach the goal zone was age-dependent favoring mice at 4 months of age. We showed previously that moving time represents encoding of spatial information and resting time represents recall of previously learned spatial information. The average moving time decreased from 69.8 ± 5.3 s (mean ± SEM), 69.7 ± 8.0 s, and 78.9 ± 4.9 s to 17.0 ± 2.3 s (p < 0.001 ), 24.7 ± 2.7 s (p < 0.001), and 31.0 ± 3.5 s (p < 0.001) at 4, 9, and 12 months of age, respectively. The average resting time decreased from 34.9 ± 5.6 s, 22.2 ± 4.2 s, and 41.7 ± 5.3 s to 3.6 ± 1.2 s (p < 0.001), 5.3 ± 1.8 s (p = 0.009), and 22.7 ± 4.9 s (p = 0.007) at 4, 9, and 12 months of age, respectively. We conclude that age-related deficits of spatial memory in mice manifest with an encoding deficit prior to a retrieval deficit.展开更多

文摘An experimental assessment of the effectiveness of university counselling was conducted through the “Stress Drawing Recall” Technique applied before and after a clinical colloquium with 70 university students of both genders, aged 18 - 35 years, who had requested this service. Another 70 students waiting to undergo the colloquium were interviewed as a control group. Two parallel series of drawings depicting personal stress situations were collected and, after evaluation by three expert judges in “double-blind” conditions, led to establishing five forms of development of the graphic language from the first to second drawing, defined as follows: a) distension, with a reduction in stress indicators and increase in comfort indicators;b) explicit representation of conflict resolution;c) appearance of new elements, with persisting conflict;d) increase in stress indicators;e) invariant or equivalent repetition of the stress drawing. Results showed that students who underwent the clinical colloquium (experimental group) changed their stress drawings mainly in the direction of distension and conflict resolution, while the control group had more invariant or equivalent repetition of the stress situation (?= 62.77;p < 0.001). The events depicted in the stress drawings were divided into three categories: a) limited short-term stressful situations due to mainly external agents;b) externally induced stressful situations with intense emotional resonance;c) wide-ranging long-lasting stressful situations with great involvement of the self. The participants were divided into: a) very anxious subjects;b) averagely anxious subjects;c) not very anxious subjects, on the basis of their scores on two questionnaires: the MPI (1959) and the STAI (1970).

Methods: Data were obtained from the Physical Activity in Young Adults Study, a 10- year follow-up study of 12 - 16 year old adolescents. Five hundred twenty-eight young adults, mean age 24.5 (±1.0) years, completed a GPAq regarding current and past (adolescent) PA. GPAq answers were used to determine whether young adults could accurately rank their past (adolescent) PA levels relative to peers of the same age and sex. GPAq responses were compared with actual self-reported PA levels assessed by the Modifiable Activity Questionnaire for Adolescents (MAQ-A;collected during adolescence). For adolescent PA, an average of 4 years of activity from the MAQ-A 1990-1993, was used. Results: Regardless of gender, Jonckheere-Terpstra tests for trend (p < 0.0001) suggest significant linear trends across categories of PA level for the MAQ-A. Higher perceived PA tracked with greater past PA activity and lower perceived PA tracked with lower past PA activity. Conclusions: Young adults who classified themselves as more active as an adolescent were found to be relatively more active based upon self-reported activity from recall questionnaires collected during that time. These findings suggest that young adults can reasonably estimate relative PA levels during their adolescent years with GPAq. Global physical activity questions may be valid for the assessment and classification of previous PA levels.
文摘Background: Early detection of dementia is currently of great interest and of crucial importance for the implementation of preventive measures and treatment of the disease. Impairment in verbal episodic memory, and in particular in a delayed recall phase, is considered one of the early markers of progression from mild cognitive impairment (MCI) to dementia. Therefore, having cognitive screening instruments with predictive value for progression is of utmost importance. Objective: The purpose of this work is to show the predictive value, sensitivity and specificity of the Memory Impairment Screen with delayed recall (MIS-DR) to predict conversion to dementia in patients with MCI. Methods: In retrospective study 502 patients over 60 years old, evaluated in the Older Adult Functional Evaluation Unit of our hospital for cognitive complaint, were diagnosed with MCI. They were followed up to assess conversion to dementia. Results: During follow up, 144 participants developed dementia (28.6%, 95% CI 24.76 - 32.85) and the average time of progression to dementia were 23 months (SD 13.2). The cut-off point was established below 6 for MIS-DR and it showed a sensitivity of 76% (95% CI 68.77 - 77.84) and a specificity of 56% (95% CI 50.44 - 61.58), with a positive predictive value of 41% (95% CI 34.78 - 47.6) and a negative predictive value of 85% (95% CI 80.53 - 91.11) for predicting progression to dementia. Of those patients who obtained a MIS-DR score below 6, 41% developed dementia, in contrast to 14.53% of those with a score above or equal to 6, OR 4.09 (95% CI 2.64 - 6.34), p 0.00001. There were no significant differences in terms of gender, education level or vascular risk factors among patients who converted and those who did not convert to dementia. Conclusion: We believe that MIS-DR is a useful and valid test to detect episodic memory impairment and to identify patients at risk of progression to dementia.

文摘This paper examines the noise and rotation resistance capacity of Hopfield Neural Network (HNN) given four corrupted traffic sign images. In the study, Signal-to-Noise Ratio (SNR), recall rate and pattern complexity are defined and employed to evaluate the recall performance. The experimental results indicate that the HNN possesses significant recall capacity against the strong noise corruption, and certain restoring competence to the rotation. It is also found that combining noise with rotation does not further challenge the HNN corruption resistance capability as the noise or rotation alone does.

文摘This study assessed the relationships between recall of positive and negative events, API （attention to positive） and ANI （attention to negative information）, and perception of happiness, with the hypothesis that recall affects the perception of happiness and that ANI and API affect recall. One hundred and five women filled in the APNI scale to assess API and ANI and were asked to listen to and recall a story presenting both positive and negative events, and provide an assessment of the character perceived happiness. Finally, they were asked to choose an ending for the story. Results showed that recall is related to the perception of happiness more than API and ANI, and that relationships occur among recall, API, ANI, and perception of happiness. A positive ending for the story was preferred. Discussion focuses on the implications of individual differences in paying attention to and recall positive and negative information.
文摘On aging, spatial memory declines to some degree in both, rodents and humans. It is unknown, however, whether aging brings about a decline of encoding and retrieval of spatial information in parallel. The present study examined spatial encoding and retrieval in male CD-1 mice at 4, 9, and 12 months of age in a complex dry-land maze. The total time to reach the goal zone was age-dependent favoring mice at 4 months of age. We showed previously that moving time represents encoding of spatial information and resting time represents recall of previously learned spatial information. The average moving time decreased from 69.8 ± 5.3 s (mean ± SEM), 69.7 ± 8.0 s, and 78.9 ± 4.9 s to 17.0 ± 2.3 s (p < 0.001 ), 24.7 ± 2.7 s (p < 0.001), and 31.0 ± 3.5 s (p < 0.001) at 4, 9, and 12 months of age, respectively. The average resting time decreased from 34.9 ± 5.6 s, 22.2 ± 4.2 s, and 41.7 ± 5.3 s to 3.6 ± 1.2 s (p < 0.001), 5.3 ± 1.8 s (p = 0.009), and 22.7 ± 4.9 s (p = 0.007) at 4, 9, and 12 months of age, respectively. We conclude that age-related deficits of spatial memory in mice manifest with an encoding deficit prior to a retrieval deficit.
文摘There are no explicit laws concerning food recalls in China; moreover, some related regulations have weaknesses. China should first create a system of laws and regulations governing food recalls, establish a system to recall defective food, and strengthen administrative and legal remedial mechanisms related to consumer rights.
文摘The Administrative Regulation on the Recall of Defective Motor Vehicles has officially entered into force on October 1st, 2004, which means the management on defective products has made a substantive progress. The enactment and enforcement of the Administrative Regulation has generated active responses in our society and drawn much attention from the automobile industry. Up to March 2005, there have been 15 domestic and foreign auto manufacturers initiating voluntary recalls since the Administrative Regulation on the Recall of Defective Motor Vehicles was issued in March 2004, and 312864 vehicles have been recalled. All the relevant firms, types, models, numbers and the date are as the following table 1.
