    The Mini-Mental State Examination is a widely used cognitive screening measure. The purpose of the present study was to assess how 5 specific clusters of Mini-Mental State Examination items (ie, subscores) correlate with and predict specific areas of daily functioning in dementia patients, 61 patients with varied forms of dementia were administered the Mini-Mental State Examination and an observation-based daily functional test (the Direct Assessment of Functional Status). The results revealed that the orientation and attention subscores of the Mini-Mental State Examination correlated most significantly with most functional domains. The Mini-Mental State Examination language items correlated with all but the shopping and time orientation tasks, while the Mini-Mental State Examination recall items correlated with the Direct Assessment of Functional Status time orientation and shopping tasks. Stepwise regression analyses found that among the Mini-Mental State Examination subscores, orientation was the single, best independent predictor of daily functioning.

    As populations age, screening instruments for cognitive impairment and dementia will become of increasing importance in clinical practice. Mini-Mental Parkinson (MMP), a derivative of the Mini-Mental State Examination (MMSE), was originally described as a cognitive screening instrument for use in Parkinson's disease. Its item content addresses some of the acknowledged shortcomings of the MMSE. Pragmatic use of MMP in general cognitive clinics has not previously been examined. To compare the performance of two scales, Mini-Mental Parkinson (MMP) and the Mini-Mental State Examination (MMSE), as cognitive screening instruments for dementia in a memory clinic population. MMP was administered prospectively to 201 consecutive new patient referrals independent of other tests used to establish dementia diagnosis according to standard diagnostic criteria (DSM-IV). Diagnostic utility of MMP for dementia was measured and compared with MMSE. MMP proved easy to use and acceptable to patients. Optimal test accuracy (0.86) was at MMP cutoff of ≤ 17/32, with sensitivity 0.51, specificity 0.97, positive predictive value 0.83, negative predictive value 0.87, and area under Receiver Operating Characteristic curve 0.89. Using a higher cutoff (≤ 29/32), MMP sensitivity was 1.00 with specificity 0.70. MMP scores correlated with MMSE (r = 0.93) and diagnostic agreement was high (κ = 0.85). MMP is a useful screening instrument in the memory clinic setting, with patients who fall below the designated cutoff requiring further investigation to ascertain a cause for their cognitive impairment.

    The Mini-Mental State Examination is one of the most widely used screening tests for the adult population in daily neurologic practice. The aim of this study was to describe and to analyze the results of the Mini-Mental State Examination administered to Spanish children and to assess the relationship between Mini-Mental State Examination scores and the child's mental age/intelligence quotient. The study population included 181 children whose ages ranged between 4 and 12 years. The neuropsychologic battery consisted of the Mini-Mental State Examination and Kaufman Brief Intelligence Test. Percentiles were obtained for the Mini-Mental State Examination total score according to age ranges. Performance gradually increased from 4 to 10 years of age when a plateau in the total Mini-Mental State Examination score was reached. At the age of 6 years, results exceeded 24 on average. Pairwise mean comparisons showed statistically significant differences between the age groups (P Mini-Mental State Examination score correlated significantly with the child's chronologic (r = 0.80, P mental (r = 0.76, P Mini-Mental State Examination in a Spanish child population as well as a first step for the assessment of the usefulness of this instrument as a cognitive screening tool for children's development.

    Short cognitive tests are routinely used in clinical practice to detect and screen for cognitive impairment and dementia. These cognitive tests should meet minimum criteria for both applicability and psychometric qualities. The Mini-Mental State Examination (MMSE) is the most frequently applied short cognitive test, and the article introducing it remains a milestone in the history of medicine. Its main advantages are its widespread use and the extensive empirical evidence that supports it. However, the MMSE has important shortcomings, including lack of standardisation, its lack of suitability for illiterate subjects, the considerable effect of socio-educational variables on results, and its limited effectiveness for detecting cognitive impairment. Lastly, since the test is copyright-protected, using it is necessarily either costly or fraudulent. Newer available instruments do not share these shortcomings and have demonstrated greater diagnostic accuracy for detecting cognitive impairment and dementia, as well as being more cost-effective than the MMSE CONCLUSION: It is time to acknowledge the MMSE's important role in the history of medicine and grant it a deserved and honourable retirement. Its place will be taken by more effective instruments that require less time, are user-friendly and free of charge, can be applied to all individuals, and yield more equitable outcomes.

    The purpose of the study was to identify the most efficient items from the Mini-Mental State Examination for assessment of cognitive function. The Mini-Mental State Examination is the most frequently used cognitive screening instrument. However, the Mini-Mental State Examination has been criticized for insensitivity to mild cognitive dysfunction, limited memory assessment and variability in level of difficulty of the individual items. This study used secondary data analysis. Item response theory two-parameter model was used to analyse the data from the admission assessment of mental status by the Mini-Mental State Examination for 801 patients. By using item response analysis, 16 items were selected from the original 30-item Mini-Mental State Examination. The 16 items included mainly the measures of orientation, recall and attention and calculation. The internal consistency of the 16-item Mini-Mental State Examination was 0.84. The proposed new cut-off point for the 16-item Mini-Mental State Examination was 11. The correct classification rate was 0.94, the sensitivity was 100% and the specificity was 97.4%, when compared with the original 30-item Mini-Mental State Examination from the cut-off point of 24. This new cut-off point was determined for the purpose of over-identifying patients at risk so as to ensure early detection of and prevention from the onset of cognitive disturbance. Only a few items are needed to describe the subject's cognitive status. Using item response theory analysis, the study found that the Mini-Mental State Examination could be simplified. Deleting the items with less variation makes this assessment tool not only shorter, easier to administer and less strenuous for respondents, but also enables one to maintain validity as a cognitive function test for clinical setting.

    The Mini-Mental State Examination is the most commonly used cognitive screening test. In Portugal, the cut-off scores are defined according to literacy groups, but different proposals have been recommended by more representative studies. We therefore propose to confirm the influence of demographical variables, such as age and education, in the subjectâs performance; evaluating the discriminant ability of the new normative data; and to further examine the diagnostic acuity of the validated cut-off scoring for mild cognitive impairment and for the most prevalent types of dementia. Our study includes 1 441 educated subjects, divided into seven subgroups: Mild cognitive impairment, Alzheimer's disease, frontotemporal dementia, vascular dementia, dementia with Lewy bodies, community-controls and memory clinic-controls. Altogether age and education explain 10.4% of the Mini-Mental State Examination results variance, with both variables contributing significantly to the resultsâ prediction. The diagnostic acuity based on the most recent normative data was always higher than the one obtained through the validation cut-off scoring, revealing an overall excellent specificity (superior to 90%) and different sensitivity values: excellent for mild Alzheimer's disease (91%), good for dementia with Lewy Bodies (78%) and low for mild cognitive impairment (65%), frontotemporal dementia and vascular dementia (55%). The performance on the Mini-Mental State Examination is influenced by age and education, supporting the use of normative data that consider those variables. With this approach, the Mini-Mental State Examination could be a sensitive and specific instrument for the Alzheimer's disease screening among all healthcare levels. Nevertheless, its diagnostic acuity is limited in other conditions frequently seen in memory clinics, such as Mild Cognitive Impairment and other types of dementia.

    We compared the sensitivity and specificity of two delayed recall scores from the Modified Mini-Mental State (3MS) test with consensus clinical diagnosis to differentiate cognitive impairment due to Alzheimer's disease (AD) versus non-AD pathologies. At a memory disorders clinic, 117 cognitively impaired patients were administered a baseline 3MS test and received a contemporaneous consensus clinical diagnosis. Their brains were examined after death about 5 years later. Using logistic regression with forward selection to predict pathologically defined AD versus non-AD, 10-min delayed recall entered first (p = 0.001), followed by clinical diagnosis (p = 0.02); 1-min delayed recall did not enter. 10-min delayed recall scores ≤4 (score range = 0-9) were 87% sensitive and 47% specific in predicting AD pathology; consensus clinical diagnosis was 82% sensitive and 45% specific. For the 57 patients whose initial Mini-Mental State Examination scores were ≥19 (the median), 3MS 10-min delayed recall scores ≤4 showed some loss of sensitivity (80%) but a substantial gain in specificity (77%). In conclusion, 10-min delayed recall score on the brief 3MS test distinguished between AD versus non-AD pathology about 5 years before death at least as well as consensus clinical diagnosis that requires much more comprehensive information and complex deliberation.

    Cognitive impairment is frequent in cerebral palsy (CP) and there is a lack of multiprofessional screening instruments. The aim of this study was to investigate the utility of the Mini-Mental State Examination for Children (MMC), an adapted version of the Mini-Mental State Examination, in screening for cognitive impairments in children with CP. We assessed 397 Brazilian children, 310 with typical development and 87 with CP (hemiplegic and quadriplegic forms), aged 5-16 years. Association between the MMC and general intelligence was assessed by the Colored Progressive Matrices instrument. Psychometric indexes for the MMC were adequate. ROC analyses revealed effective diagnostic accuracy in all ages assessed. Cut-off values are reported. Major difficulties on the MMC were observed in children with CP, particularly individuals with the quadriplegic form. Moreover, the MMC showed moderate correlation with the intelligence test, and was reliable in discriminating, among clinical cases, those with poorer cognitive abilities. The MMC could be useful as a multiprofessional screening instrument for cognitive impairment in children with hemiplegic CP. Results of the MMC in quadriplegic CP children should be interpreted with caution. Diagnosis should be confirmed by further psychological testing.

    The Modified Mini-Mental State Examination (3MS) is an expanded and modified version of the Mini-Mental State Examination (MMSE). Research demonstrates that the reliability, validity, specificity, and sensitivity of the 3MS are superior to that of the MMSE in detecting cognitive impairment. The Farsi version of the 3MS (F-3MS) was examined as a screening tool for dementia among elderly Iranians. The F-3MS and the Clock Drawing Test (CDT) were administered to 58 patients with dementia and 145 control subjects with normal cognition, aged 60 to 85 years. The difference between groups on the mean total scores of the F-3MS was statistically significant (dementia = 60.65 ± 9.89, control = 80.73 ± 8.26; df = 201, t = 14.75, p validity of the F-3MS. The F-3MS can be used as a valid and reliable measure for dementia screening among elderly Iranians.

    The Mini-Mental State Exam (MMSE) is commonly used to screen cognitive function in a clinical setting. The measure has been published in over 50 languages; however, the validity and reliability of the MMSE has yet to be assessed with the culturally Deaf elderly population. Participants consisted of 117 Deaf senior citizens, aged 55-89 (M = 69.44, SD = 8.55). Demographic information, including state of residence, age, and history of depression, head injury, and dementia diagnoses, were collected. A standard form of the MMSE was used with modification of test administration and stimuli including translation of English test items into a sign-based form and alteration of two items in order to make them culturally and linguistically appropriate. Significant correlations were observed between overall test score and education level (r = .23, p = .01) as well as test score and age (r = -.33, p validate the use of this measure with the culturally Deaf population.

    The aim of this study was standardization and validation of the Mini-Mental State Examination (MMSE) in the general Croatian aging population. Three-hundred and forty-four participants underwent the MMSE test, 217 cognitively healthy subjects without neurological and psychiatric disorders and 127 patients with mild cognitive impairment (MCI) or dementia. The optimal cutoff point for screening of the general Croatian population (cognitively healthy vs. MCI and dementia) is 26/27; in the Croatian population aged ≥65 years, the cutoff point is 24/25, whereas for screening of highly educated persons (≥14 years of education) aged ≥65 years a higher cutoff point should be used (26/27). MMSE results when standardized and validated in a certain population might better contribute to recognition of the individuals at risk that should be directed to dementia outpatient clinics.

    We aim to provide a conversion between Addenbrooke's Cognitive Examination III (ACE-III) and Mini-Mental State Examination (MMSE) scores, to predict the MMSE result based on ACE-III, thus avoiding the need for both tests, and improving their comparability. Equipercentile equating method was used to elaborate a conversion table using a group of 400 participants comprising healthy controls and Alzheimer's disease (AD) patients. Then, reliability was assessed in a group of 100 healthy controls and patients with AD, 52 with primary progressive aphasia and 22 with behavioral variant frontotemporal dementia. The conversion table between ACE-III and MMSE denoted a high reliability, with intra-class correlation coefficients of 0.940, 0.922, and 0.902 in the groups of healthy controls and AD, behavioral variant frontotemporal dementia, and primary progressive aphasia, respectively. Our conversion table between ACE-III and MMSE suggests that MMSE may be estimated based on the ACE-III score, which could be useful for clinical and research purposes.

    Cognitive tests are used repeatedly to assess the treatment response or progression of cognitive disorders. The Montreal Cognitive Assessment (MoCA) is a valid screening test for mild cognitive impairment. The aim of our study was to establish 90% reliable change indices (RCI) for the MoCA together with the Mini-Mental State Examination (MMSE) in cognitively healthy older adults. We analyzed 197 cognitively healthy and functional independent volunteers aged 60-94 years, who met strict inclusion criteria for four consecutive years. The RCI methods by Chelune and Hsu were used. For 1, 2, and 3 years, the 90% RCI for MoCA using Chelune's formula were -4 ≤, ≥4; -4 ≤, ≥4 and -5 ≤, ≥4 points, respectively, and -3 ≤, ≥3 for the MMSE each year. Ninety percent RCI for MoCA using Hsu's formula ranged from -6 to 0, respectively, and +3 to +8 dependent on the baseline MoCA. Our study demonstrated RCI for the MoCA and MMSE in a 3-year time period that can be used for the estimation of cognitive decline or improvement in clinical settings.

    Previous studies have suggested that the pattern of cognitive impairment in crash involved older drivers is different from non-crash involved older drivers. This study assessed the relationship between seven areas of cognitive functioning (orientation to time, orientation to place, registration, attention and calculation, recall, language, and visual construction) on the Mini-Mental State Examination (MMSE) collected at baseline and rates of future crash involvement in a prospective population-based sample of older drivers. Motor vehicle collision involvement was obtained from the Alabama Department of Public Safety. Poisson regression was used to calculate crude and adjusted rate ratios (RR). Older drivers having difficulties in place orientation were more than 6 times (95% CI 1.90-19.86) more likely to be involved in a future crash (adjusted RR = 6.14, 95% confidence interval (CI) 1.90-19.86) and at-fault crash (adjusted RR=6.39, 95% CI 1.51-27.10). Impairment in the other cognitive areas was not associated with higher rates of crash or at-fault crash involvement. The findings were validated in an independent sample of high-risk older drivers and a similar pattern of results was observed. Spatial orientation impairment can help identify older drivers who are more likely to crash in the future.

    This study investigated whether healthy older adults with Mini-Mental State Examination (MMSE) scores above 23 exhibit cognitive impairment on neuropsychological tests. Participants completed the MMSE and a neuropsychological battery including tests of 10 domains. Results were compared to published normative data. On neuropsychological testing, participants performed well on measures of naming and recall but showed mild to moderate impairment in working memory and processing speed and marked impairment in inhibition, sustained attention, and executive functioning. Almost everyone (91%) scored at least 1 standard deviation (SD) below the mean in at least 1 domain. The median number of domains in which individuals scored below 1 SD was 3.0 of 10.0, whereas over 21% scored below 1 SD in 5 domains or more. With the strictest of definitions for impairment, 20% of this population scored below 2.0 SDs below the norm in at least 2 domains, a necessary condition for a diagnosis of dementia. The finding that cognitive impairment, particularly in attention and executive functioning, is found in healthy older persons who perform well on the MMSE has clinical and research implications in terms of emphasizing normal variability in performance and early identification of possible impairment. © The Author(s) 2016.

    Tests requiring the pronunciation of irregular words are used to estimate premorbid cognitive ability in patients with clinical diagnoses, and prior cognitive ability in normal ageing. However, scores on these word-reading tests correlate with scores on the Mini-Mental State Examination (MMSE), a widely used screening test for possible cognitive pathology. This study aimed to test whether the word-reading tests' correlations with MMSE scores in healthy older people are explained by childhood IQ or education. Wechsler Test of Adult Reading (WTAR), National Adult Reading Test (NART), MMSE scores and information about education were obtained from 1024 70-year-olds, for whom childhood intelligence test scores were available. WTAR and NART were positively correlated with the MMSE (r ≈ 0.40, p < 0.001). The shared variance of WTAR and NART with MMSE was significantly attenuated by ~70% after controlling for childhood intelligence test scores. Education explained little additional variance in the association between the reading tests and the MMSE. MMSE, which is often used to index cognitive impairment, is associated with prior cognitive ability. MMSE score is related to scores on WTAR and NART largely due to their shared association with prior ability. Obtained MMSE scores should be interpreted in the context of prior ability (or WTAR/NART score as its proxy).

    Validation study of the Mini-Mental State Examination in Urdu language for Pakistani population. This study was conducted primarily to validate and determine the optimal cutoff score in the diagnosis of dementia among Pakistani's and study the effects of gender and education on the MMSE performance in our population. Four hundred participants took part in the study. Patient with dementia recruited from five major hospitals from Pakistan. The MMSE was translated into Urdu. There were 61 men and 39 women in dementia group and 225 men and 75 women in the control group. The mean score of Urdu MMSE were lower in patients with dementia 18.5 ± 5.6 (range 0-30) as compared to the controls 26.8 ± 2.6 (range 7-30). This difference between groups was statistically significant (p<0.001). Educational based MMSE score below 15 yielded perfect sensitivity and specificity for the diagnosis of dementia. These finding confirm the influence of level of education on MMSE score and education stratified cutoff scores should be used while screening for cognitive impairment in this population.

    To examine factors that may have impact on the Mini-Mental State Examination (MMSE) screening validity, which could lead to further establishing the general model of the MMSE score in Chinese health elderly and to improve the screening accuracy of the existing MMSE reference. Based on the data of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), the MMSE scores of 19,117 normal elderly and 137 dementia patients who met the inclusion criteria were used for the analysis. The area under the curve (AUC) and validity indexes were used to compare the screening accuracy of various criteria. Multiple linear regression was used to identify factors that had impact on the MMSE score for both the normal and dementia elderly. Descriptive analysis was performed for differences in the MMSE scores by age trends and gender between the normal and dementia elderly. The AUC of MMSE was ≥0.75(Pvalidity of MMSE in CLHLS is not affected by educational level. The analysis of factors that may impact on the MMSE screening validity are gender, age, vision and residence which with validity identification. These four factors can be used as assist tool of MMSE in the screening of dementia to improve the screening accuracy.

    The objective of this study was to determine the reliability of the Mini-Mental State Examination (MMSE) administration via telehealth with a focus on the auditory and visual test components. Reliability was assessed through use of an in-person collaborator and by assessment of faxed test copies. The MMSE was administered via telehealth with the assistance of a face-to-face collaborator. Patient responses were recorded by both the remote and in-person nurse and compared item by item; total scores for each subject were also compared. Visual items were assessed through a blinded separate scoring of a faxed copy. Percent agreement per item and total score were calculated and correlations between scores were determined by Pearson correlation coefficients. Mean score differences and associated 95% confidence intervals were calculated. Eighty percent of individual items demonstrated remote to in-person agreement of >95% and all items were >85.5% in agreement. Pearson correlation coefficients demonstrated high correlations (>0.86) between 80% of the items examined. Mean differences in scored test items were not significantly different from zero. This study demonstrates the utility of using telehealth for cognitive assessment by MMSE. It supports the use of telehealth to improve healthcare access among patients for whom distance, cost, and mobility are potential barriers to attending face-to-face clinical visits. Continued validation and reliability testing is warranted to ensure that all healthcare provided via telehealth maintains an equal quality level to that of in-person care.

    The mini-mental state examination (MMSE) was adapted by individual countries according to their languages and cultures, though it has not been systematically compared. The objective of this study was to compare the linguistic and cultural variations of the MMSE used in various Asian countries. With this, we can analyze the strengths and weaknesses of the MMSE and consider using a common version in future international clinical studies in Asia. We collected the MMSEs used in 11 Asian nations. After translating those into English, we compared them to understand the differences in the questionnaires with regard to cultural aspects. Many items may be applicable or comparable with a little modification, for Asian countries. However, attention and calculation and repetition may be incomparable. There were some differences in the contents and the ways to administer. The lack of consideration of the cultural differences and their influences on the interpretation of the same cognitive test makes cross-cultural studies difficult. Some items of MMSE tasks need readjusting for, if any, multi-national studies. This study might serve as a first step in the development of a standardized cross-cultural cognitive instrument, especially in Asia.

    Background Brief cognitive screening measures are valuable tools for both research and clinical applications. The most widely used instrument, the Mini-Mental State Examination (MMSE) is limited in that it must be administered face-to-face, cannot be used in participants with visual or motor impairments, and is protected by copyright. Alternative screening instruments, such as the Telephone Interview for Cognitive Status (TICS) have been developed and may provide a valid alternative with comparable cut point scores to rate global cognitive function. Methods MMSE, TICS-30, and TICS-40 scores from 746 community dwelling elders who participated in the Aging, Demographics, and Memory Study (ADAMS) were analyzed with equipercentile equating, a statistical process of determining comparable scores based on percentile equivalents on different forms of an examination. Results Scores from the MMSE and the TICS-30 and TICS-40 corresponded well and clinically relevant cut point scores were determined; for example, an MMSE score of 23 is equivalent to 17 and 20 on the TICS-30 and TICS-40, respectively. Conclusions These findings provide scores that can be used to link TICS and MMSE scores directly. Clinically relevant and important MMSE cut points and the respective ADAMS TICS-30 and TICS-40 cut point scores have been included to identify the degree of cognitive impairment among respondents with any type of cognitive disorder. These results will help with the widespread application of the TICS in both research and clinical practice. PMID:19647495

    The present cross-sectional study aimed at assessing muscle strength of hands, the dominant arm and legs in Spanish institutionalized elderly people according to sex, age and cognitive status. A total of 153 elderly subjects (102 females, 51 males, mean age 83.6 ± 6.8 years) living in the region of Madrid were measured for handgrip strength (kg) with a Takei TKK 5101 digital dynamometer (range 5-100 kg, precision 0.1 kg), and arm and leg endurance strength (repetitions) according to the Rikli and Jones tests. Cognitive status was determined with the Mini-Mental State Examination (MMSE). The values for men and women were, respectively: 23.5 ± 7.3 kg and 11.6 ± 4.6 kg (right handgrip), 22.0 ± 7.8 kg and 10.7 ± 4.8 kg (left handgrip), 13 ± 5 and 10 ± 5 repetitions (arm strength), 8 ± 5 and 5 ± 4 repetitions (legs strength), and 21 ± 6 and 17 ± 7 (MMSE score). All parameters were significantly higher for men (P ≤ 0.01), but strength decline with age was less pronounced in women. In all MMSE groups, lower strength was associated with lower cognitive status. Strength values were lower in older subjects in both sexes; this difference was higher in men than in women. Higher strength values were associated with better cognitive status, which was the most influencing variable, even more than sex and age. © 2013 Japan Geriatrics Society.

    Hearing loss is associated with cognitive decline in the elderly. However, it is unknown if the use of hearing aids (HAs) is associated with enhanced cognitive function. In a cross-sectional study at an academic medical center, participants underwent audiometric evaluation, the Mini-Mental State Exam (MMSE), and the Trail Making Test, Part B (TMT-B). The impact of use versus disuse of HAs was assessed. Performance on cognitive tests was then compared with unaided hearing levels. HA users performed better on the MMSE (1.9 points; rank-sum, p = 0.008) despite having worse hearing at both high frequencies (15.3-dB hearing level; t test, p < 0.001) and low frequencies (15.7-dB hearing level; t test p < 0.001). HA use had no effect TMT-B performance. Better performance on the MMSE was correlated with both low frequency (ρ = -0.28, p = 0.021) and high frequency (ρ = -0.21, p = 0.038) hearing level, but there was no correlation between performance on the TMT-B and hearing at any frequency. Despite having poorer hearing, HA users performed better on the MMSE. Better performance on cognitive tests with auditory stimuli (MMSE) but not visual stimuli (TMT-B) suggests that hearing loss is associated with sensory-specific cognitive decline rather than global cognitive impairment. Because hearing loss is nearly universal in those older than 80 years, HAs should be strongly recommended to minimize cognitive impairment in the elderly.

    Stroke often leads to disability, and poststroke survivors often have limited accessibility to medical facilities. For such patients, mobile videoconferencing technology offers an opportunity to perform follow-up assessment and appropriate management of cognitive impairment. We aimed to determine the validity of the Korean version of the Mini-Mental State Examination (MMSE-K) when administered using a smartphone. Thirty patients with ischemic or hemorrhagic stroke were included in this study (20 males, 10 females; mean age, 69.8 ± 12.9 years). Both face-to-face and remote assessments of cognitive function through MMSE-K were performed for each patient at an interval of at least 3 days. Additionally, an in-person collaborator evaluated the MMSE-K score during the remote assessment. A smartphone and a tablet were used by the patient and the examiner, respectively, and remote connection was mediated using a dedicated videoconferencing application. The MMSE-K scores obtained through face-to-face, remote, and in-person assessments were compared using the Wilcoxon signed rank test and the Spearman correlation analysis. There was good agreement between face-to-face and remote assessments, as well as between remote assessment and in-person collaborator's evaluation regarding total MMSE-K score and subscores for each MMSE-K domain (orientation, memory, attention/calculation, language, and visuospatial function). Remote assessment can be a useful clinical evaluation method, and this study confirmed the validity. The smartphone represents a promising tool for the assessment of cognitive function in clinical practice, but further research into the intra- and inter-rater reliability of observations is warranted.

    To evaluate the diagnostic accuracy (DA) of the Mini-Mental State (MMS) for the detection of cognitive impairment (CI) in Primary Care (PC) and to determine the best conditions of use for that purpose. Pooled analysis of two prospective, double blind, studies on the evaluation of diagnostic tools with complete verification that were conducted in Madrid and Granada (Spain). The MMS was administered in PC and the final cognitive diagnosis (gold standard) was made in Specialized Care. Subjects with cognitive complaints or suspected of having CI were consecutively recruited in the PC clinic. The DA of the MMS was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC). The best cut-off point was selected according to the ratio of cases correctly classified (RCC) and to the kappa index. Direct (MMSd) and age- and education-adjusted (MMSa) total scores were analyzed separately. In the total sample of 360 subjects (214 CI), the DA of the MMSd was significantly superior to that of the MMSa (0.84±0.02 vs 0.82±0.02, p≤.001). The yield obtained by the best cut-off point of the MMSd (22/23) was modest (RCC 0.77, kappa 0.52±0.05) and was not improved by any MMSa cut-off point. The DA of the MMS for detection of CI in PC was modest and did not improve with adjustment of the score by age and education. The best cut-off point was 22/23, inferior to the usually recommended cut-off. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Chinese nationwide norms of the Mini-Mental State Examination (MMSE) have not been established despite its wide use. To obtain norms for the MMSE based on age, gender, education, and rural or urban residences and to determine the optimal cut-off points of the MMSE in elderly Chinese. A cross-sectional study was conducted in Chinese community residents aged 65 years or over selected by cluster random sampling. The MMSE was administered to 9,629 subjects (7,110 cognitively normal, 2,024 with mild cognitive impairment, and 495 with dementia). The demographic influences on MMSE scores were investigated and the norms were established considering those factors. Receiver operating characteristic (ROC) analysis was used to determine the optimal cut-off points. Years of education (standardized β= 0.399), rural residence (standardized β= -0.261), age (standardized β= -0.198), and being female (standardized β= -0.101) had significant effects on MMSE scores (p < 0.001). Accordingly, we presented the demographic-stratified normative data for the MMSE. The optimal cut-off points for dementia screening were 16/17 for illiterate (sensitivity 87.6% and specificity 80.8%), 19/20 for individuals with 1-6 years of education (sensitivity 93.6% and specificity 92.7%), and 23/24 for individuals with 7 or more years of education (sensitivity 94.3% and specificity 94.3%). We provide the age-, gender-, education-, and residence-specific reference norms for the MMSE derived from an investigation of a large-scale, multicenter, nationwide representative Chinese elderly population. It could be of great improvement for the use of the MMSE in dementia screening in Chinese elderly population.

    To adapt to Spanish and to determine the convergent validity of a Telephone Mini-Mental State Examination (t-MMSE) in order to assess the cognitive functions in Alzheimer's disease (AD) patients. Prospective and observational study of a clinical sample consisting of patients with dementia from a memory clinic. Consecutive sampling of participants was used and convergent validity of the t-MMSE and MMSE scores was determined using several statistics measures. Patients were randomly assigned depending on the administration of the in-person/telephone test (MMSE and t-MMSE) or telephone/in-person (t-MMSE and MMSE) test within a 1- to 7-day interval. The effect of the confusion variables (age, gender, years of education, dementia severity, presence or absence of hearing impairment and administration order) on the concordance between the in-person and telephone MMSE versions was analysed. After translating and retranslating the t-MMSE, of 141 participants, 77.47% subjects completed the protocol of the study. For the total score, the statistics for the convergent validity suggested a high consistency, independently of the order of test administration (intraclass correlation coefficient = 0.87, Spearman's rho = 0.77); for the all subscores, it suggested moderate and good correlations. The difference between subscores did not range more than 1 point in any case. Confusion variables did not affect the variability of the performance scores between t-MMSE and MMSE. The t-MMSE can be used as a good tool to estimate the MMSE score of patients with dementia.

    Several studies have identified moderate reliability and validity for the Mini-Mental State Examination (MMSE). Some researchers showed the superiority of other dementia screening tests over the MMSE considering the test quality criteria. The aim of this study was the evaluation of MMSE, especially in the area of geriatrics. MMSE and DemTect were carried out with 154 geriatric patients: 71 persons without cognitive impairment and 83 persons without delirium showed cognitive impairments as revealed by the DemTect. In addition, we also applied the Clock-Drawing-Test (CDT), Reisberg-Scale, Geriatric Depression-Scale (GDS, 15-item version) and the Confusion-Assessment-Method (CAM). According to the multitrait-multimethod approach, MMSE's convergent and divergent validity is similar to that of the DemTect. Both tests correlate only moderately with Spearman (r = 0.609) and revealed similar results for dementia in 57.1 % of the patients. MMSE showed low reliability and moderate reliability (Cronbach's α = 0.82) when ten items with low discriminatory power were excluded from the total test score. Difficulty of all items is only moderate (p = 0.86) and only eight items of the MMSE showed good test difficulty. All in all, DemTect and MMSE are not interchangeable. The MMSE estimates the average cognitive impairment of patients as considerably less pronounced than the DemTect. MMSE is, thus, not an instrument that would be recommended for the identification of mild cognitive impairment. In this case, tests with higher reliability and validity should be used.

    This study aimed to examine the validity and item-response characteristics of the Mini-Mental State Examination (MMSE), which is used for assessing cognitive function, in Japanese older adults. Factor analysis and item response analysis were carried out for MMSE responses (n = 1971) from older adults living in the community (n = 1339) or in a nursing home (n = 632), including Alzheimer-type dementia (n = 330), vascular dementia (n = 36), frontotemporal dementia (n = 7), mixed Alzheimer-type and frontotemporal type dementia (n = 27), and age-related cognitive decline (n = 29). When choosing the cut-off score of 23 points for the MMSE, sensitivity and specificity for each item were calculated. A three-factor solution was found to be most appropriate by factor analysis: complex processing, simple processing and working memory. The item characteristics curves showed unidimensionality with high reproducibility. We identified a simplified scale comprising 10 items in all participants: "naming", "three-step command", "registration", "repeat a sentence", "write a complete sentence", "copies drawing of two polygons", "orientation to place", "delayed recall", "orientation to time" and "serial sevens" tasks. Sensitivity and specificity for both "year" task and "day" task were more than 90% ("year": sensitivity 92.5%, specificity 96.3%; "day": sensitivity 92.4%, specificity 91.7%). For the Alzheimer-type dementia patients, the five-factor solution was suggested by factor analysis and the MMSE also had unidimensionality in terms of level of difficulty. We found that the MMSE had multiple cognitive areas. We showed that the MMSE could be used as an essentially unidimensional measure of cognitive ability and the question about orientation to time might be useful in the simplest assessment to identify cognitive dysfunction. © 2011 Japan Geriatrics Society.

    To determine the validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) as screening tools for cognitive impairment after stroke. Cognitive assessments were administered over 2 sessions (1 week apart) at 3 months post-stroke. Scores on the MoCA and MMSE were evaluated against a diagnosis of cognitive impairment derived from a comprehensive neuropsychological battery (the criterion standard). Sixty patients participated in the study [mean age 72.1 years (SD = 13.9), mean education 10.5 years (SD = 3.9), median acute NIHSS score 5 (IQR 3-7)]. The MoCA yielded lower scores (median = 21, IQR = 17-24; mean = 20.0, SD = 5.4) than the MMSE (median = 26, IQR = 22-27; mean = 24.2, SD = 4.5). MMSE data were more skewed towards ceiling than MoCA data (skewness = -1.09 vs -0.73). Area under the receiver operator curve was higher for MoCA than for MMSE (0.87 vs 0.84), although this difference was not significant (χ(2) = 0.48, P = 0.49). At their optimal cut-offs, the MoCA had better sensitivity than the MMSE (0.92 vs 0.82) but poorer specificity (0.67 vs 0.76). The MoCA is a valid screening tool for post-stroke cognitive impairment; it is more sensitive but less specific than the MMSE. Contrary to the prevailing view, the MMSE also exhibited acceptable validity in this setting. © 2013 John Wiley & Sons A/S.

    The Mini-Mental State Examination (MMSE) has been utilized for the diagnosis of hepatic encephalopathy (HE). However, its threshold of abnormality has not been formally tested in patients with cirrhosis and its diagnostic/prognostic validity remains unknown. The aim of this study was to assess it in a large group of well-characterized outpatients with cirrhosis and no overt HE. One-hundred-and-ninety-one patients underwent clinical assessment, MMSE, electroencephalography (EEG) and paper-and-pencil psychometry (PHES); 117 were followed up for 8 ± 5 months in relation to the occurrence of HE-related hospitalizations. On the day of study, 81 patients (42%) had abnormal EEG and 67 (35%) abnormal PHES; 103 (60%) had a history of HE. Average MMSE was 26.6 ± 3.5; 22 (19%) patients had abnormal MMSE based on the standard threshold of 24. Patients with abnormal EEG/PHES/history of HE had worse MMSE performance than their counterparts with normal tests/negative history (25.7 ± 4.2 vs. 27.3 ± 2.7; P < 0.01; 25.5 ± 3.2 vs. 27.9 ± 1.8, P < 0.0001; 26.3 ± 3.7 vs. 27.4 ± 2.6, P < 0.05, respectively). Based on the above results, MMSE thresholds of 26 and 27 were tested against abnormalities in clinical/EEG/PHES indices and significant associations were observed. An MMSE threshold of 26 was also a predictor of HE-related hospitalization (Cox-Mantel: P = 0.001); patients with MMSE <26 were significantly older than those with MMSE ≥26 but comparable in terms of liver dysfunction and ammonia levels. When MMSE items were considered separately, those which correlated most significantly with standard HE indices where spatial orientation and writing. In conclusion, an MMSE <26 identifies older patients with cirrhosis who are more prone to manifest HE signs.

    To evaluate the psychometric properties of Mini-Mental State Examination (MMSE) in patients with acquired brain injury in Turkey. A total of 207 patients with acquired brain injury were assessed. Reliability was tested by internal consistency and the person separation index; internal construct validity by Rasch analysis; external construct validity by correlation with cognitive disability; and cross-cultural validity by differential item functioning analysis compared with Italian MMSE data. Reliability was adequate with a Cronbach's alpha of 0.75 and person separation index of 0.76. After collapsing some categories, and adjustment for differential item functioning, internal construct validity was supported by fit of the data to Rasch model. Differential item functioning for culture was found in 2 items and after adjustment, data could be pooled between Turkey and Italy. External construct validity was supported by expected associations. The Turkish version of the Mini-Mental State Examination can be used as a cognitive screening tool in acquired brain injury. Cross-cultural validity between Italy and Turkey is supported, given appropriate adjustment for differential item functioning. However, shortfalls in reliability at the individual level, as well as the presence of differential item functioning suggest that a better instrument should be developed to screen for cognitive deficits following acquired brain injury.

    We intended to define the role of the National Institutes of Health Stroke Scale and the Mini-Mental State Examination in identifying adverse neurologic outcomes in a large international sample of patients undergoing cardiac surgery. We evaluated 4707 patients undergoing cardiac surgery with cardiopulmonary bypass at 72 centers in 17 countries between November 1996 and June 2000. Prespecified overt neurologic outcomes were categorized as type I (clinically diagnosed stroke, transient ischemic attack, encephalopathy, or coma) or type II (deterioration of intellectual function). The National Institutes of Health Stroke Scale and Mini-Mental State Examination were administered preoperatively and on postoperative day 3, 4, or 5. Receiver operating characteristic curves were plotted to determine the predictive value of worsening in National Institutes of Health Stroke Scale and Mini-Mental State Examination scores with respect to type I and II outcomes. The receiver operating characteristic area under the curve for changes in National Institutes of Health Stroke Scale score (n = 4620) was 0.89 for type I outcomes and 0.66 for type II outcomes. A 1-point worsening in National Institutes of Health Stroke Scale score provided excellent discrimination (86% specificity; 84% sensitivity) of type I outcomes. The receiver operating characteristic area under the curve for changes in Mini-Mental State Examination score (n = 4707) was 0.75 for type I outcomes and 0.71 for type II outcomes. A 2-point worsening in Mini-Mental State Examination score provided only fair discrimination (73% specificity; 62% sensitivity) of type II outcomes. We used baseline controls and postoperative worsening in National Institutes of Health Stroke Scale and Mini-Mental State Examination scores to predict both serious adverse neurologic outcome and deterioration of intellectual function. Our findings provide the only reference for evaluating these tests that are used in cardiac surgical clinical

    Although not as popular as the Mini-Mental State Examination (MMSE), the modified Telephone Interview for Cognitive Status (mTICS) has some distinct advantages when screening cognitive functioning in older adults. The current study compared these 2 cognitive screening measures in their ability to predict performance on a memory composite (ie, delayed recall of verbal and visual information) in a cohort of 121 community-dwelling older adults, both at baseline and after 1 year. Both the MMSE and the mTICS significantly correlated with the memory composite at baseline (r's of .41 and .62, respectively) and at 1 year (r's of .36 and .50, respectively). At baseline, stepwise linear regression indicated that the mTICS and gender best predicted the memory composite score (R (2) = .45, P similar. Despite its lesser popularity, the mTICS may be a more attractive option when screening for cognitive abilities in this age range. © The Author(s) 2015.

    Full Text Available Using a combination of the Hopkins Verbal Learning Test (HVLT and the Mini-Mental State Examination (MMSE, we investigated the prevalence of possible dementia (DEM in community-dwelling elderly in Shanghai. Subsequently, we investigated significant risk factors for DEM and generated a DEM self-checklist for early DEM detection and case management. We found that among a total of 521 participants using a HVLT cut-off score of <19 and a MMSE cut-off score of <24, a total of 69 DEM cases were identified. Risk factors, such as advanced age (≥68 years, low education (no or primary level, self-reported history of hypertension, and self-reported subjective memory complaints (SMC were significantly predictive of DEM. The presence of ≥3 out of four of the above mentioned risk factors can effectively discriminate DEM cases from non-DEM subjects.

    Cognitive impairments have been reported to be more common in non-demented patients with Parkinson's disease (PD) and education levels play an important role in intelligence. The studies on cognitive impairments in Chinese PD patients with higher education levels and normal global cognition according to Mini-Mental State Examination Score (MMSE) have not been reported. We enrolled 69 consecutive PD patients with over 6 years education levels and a MMSE score above 24 (of 30) and performed a battery of neuropsychological scales. There are extensive cognitive domain impairments in PD patients with "normal" global cognitive according to MMSE. Montreal Cognitive Assessment (MoCA) is a highly sensitive scale to screen cognitive impairments in PD. The cutoff score of 28 on the MMSE screening for cognitive impairment in Chinese PD patients with high education levels may be more appropriate.

    This study explores whether the Mini-Mental State Examination (MMSE) could reliably exclude definite dementia and dementia-free cases from requiring more extensive neuropsychological investigations in memory clinic settings in Singapore. Patients with memory complaints referred for possible dementia underwent the MMSE, followed by standardized neuropsychological and clinical assessments which led to a consensus diagnosis. MMSE cut-off points were derived stratified for education (less and equal/above primary level). Results show that after education stratification, using an optimal Positive Likelihood Ratio (PLR) and optimal Negative Likelihood Ratio (NLR), a higher percentage of patients were correctly identified as having dementia or dementia-free, with minimal misclassification rate. The finding suggests the MMSE can be used to exclude patients not requiring full neuropsychological assessments in a memory clinic.

    We aimed to compare the Mini-Mental State Examination (MMSE) with the Mini-Cog, measuring agreement in participants' classification, using a general population sample. Cross-sectional evaluation of 609 community dwellers aged ≥60 years was performed by trained interviewers. Cohen's kappa and 95% confidence intervals (CI) were calculated to assess overall agreement, and Cronbach alphas computed to assess reliability. Two-parameter Item Response Theory models (difficulty and discrimination parameters) were used to assess discrimination. Considering MMSE cut-point for scores Mini-Cog's cut-point score Mini-Cog Mini-Cog Mini-Cog's alpha was 0.2776. Co-calibration according to inherent ability is graphically presented. Agreement between scales seems fragile in our sample. The discriminative and reliability analysis suggests a better performance for subsets of the MMSE compared with the Mini-Cog. Usefulness of calibrated scores is discussed. Copyright © 2012 S. Karger AG, Basel.

    To evaluate the effectiveness of two cognitive screening measures, the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA), in predicting driving test outcome for individuals with and without cognitive impairment. Retrospective cohort study. A clinical driving evaluation program at a teaching hospital in the United States. Adult drivers who underwent assessment with the MMSE and MoCA as part of a comprehensive driving evaluation between 2010 and 2014 (N=92). MMSE and MoCA total scores were independent variables. The outcome measure was performance on a standardized road test. A preestablished diagnosis of cognitive impairment enhanced the validity of cognitive screening measures in the identification of at-risk drivers. In individuals with cognitive impairment there was a significant relationship between MoCA score and on-road outcome. Specifically, an individual was 1.36 times as likely to fail the road test with each 1-point decrease in MoCA score. No such relationship was detected in those without a diagnosis of cognitive impairment. For individuals who have not been diagnosed with cognitive impairment, neither the MMSE nor the MoCA can be reliably used as an indicator of driving risk, but for individuals with a preestablished diagnosis of cognitive impairment, the MoCA is a useful tool in this regard. A score on the MoCA of 18 or less should raise concerns about driving safety. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    The Mini-Mental State Examination (MMSE) is widely used in population-based longitudinal studies to quantify cognitive change. However, its poor metrological properties, mainly ceiling/floor effects and varying sensitivity to change, have largely restricted its usefulness. We propose a normalizing transformation that corrects these properties, and makes possible the use of standard statistical methods to analyze change in MMSE scores. The normalizing transformation designed to correct at best the metrological properties of MMSE was estimated and validated on two population-based studies (n = 4,889, 20-year follow-up) by cross-validation. The transformation was also validated on two external studies with heterogeneous samples mixing normal and pathological aging, and samples including only demented subjects. The normalizing transformation provided correct inference in contrast with models analyzing the change in crude MMSE that most often lead to biased estimates of risk factors and incorrect conclusions. Cognitive change can be easily and properly assessed with the normalized MMSE using standard statistical methods such as linear (mixed) models. © 2014 S. Karger AG, Basel.

    In view of the differing sensitivity and specificity of the Mini-Mental State Examination (MMSE) in the non-English-speaking populations, we conducted the first validation study of the Malay version (M-MMSE) in Malaysia among 300 subjects (from the community and outpatient clinics). Three versions were used: M-MMSE-7 (serial 7), M-MMSE-3 (serial 3) and M-MMSE-S (spell 'dunia' backwards). Dementia was assessed using the criteria of the Diagnostic and Statistical Manual of Mental Disorders IV. The optimal cutoff scores were obtained from the receiver operating characteristics curves. Seventy-three patients (24.3%) had dementia and 227 (75.7%) were controls. Three hundred patients completed the M-MMSE-7, 160 the M-MMSE-3 and 145 the M-MMSE-S. All 3 versions were valid and reliable in the diagnosis of dementia. The optimal cutoff scores varied with each version and gender. In the control group, significant gender differences were observed in the patients with the lowest educational status. Increasing educational levels significantly improved the M-MMSE performance in both genders. All 3 versions of the M-MMSE are valid and reliable as a screening tool for dementia in the Malaysian population, but at different cutoff scores. In those with the lowest educational background, gender-adjusted cutoff scores should be applied. Copyright 2009 S. Karger AG, Basel.

  7. Interpreting "I don't know" use by persons living with dementia in Mini-Mental State Examinations.

    We investigate dementia patients' use of "I don't know" (IDK) in Mini-Mental State Exams (MMSEs) using objective linguistic indicators to differentiate IDK signalling lack of knowledge (LOK) from IDK used to hedge responses, affect exam progression etc. We hypothesize that increased proportional use of LOK-IDK correlates with worsening dementia severity. 189 IDK tokens were extracted from 72 MMSE interactions and coded for linguistic/social characteristics. A data-driven, discourse position/relation-based functional taxonomy for IDK in MMSE was developed and the resulting functional distribution was subjected to multiple logistic regression. Use of LOK-IDK (vs. non-LOK-IDK) is significantly correlated (p=0.01) with clinicians' subjective ratings of patients' dementia as 'severe' vs. 'mild'/'moderate', indicating that objective sociolinguistic criteria approximate physician judgments. 92% of 'severe' patients' IDKs signalled LOK, compared to only 68% of 'mild' patients', suggesting that uncritical interpretation of IDK as signalling LOK would result in 8-32% of IDK responses being mis-scored. LOK and non-LOK uses distinguished on the basis of reliable, objective usage patterns are differentially distributed among dementia severity groups. LOK-IDK serves as a supplemental indicator of dementia severity. Correct interpretation may improve diagnostic accuracy and allow clinicians to respond supportively during cognitive assessment.

    To explore the agreement between the mini-mental state examination (MMSE) and montreal cognitive assessment (MoCA) within community dwelling older patients attending an old age psychiatry service and to derive and test a conversion formula between the two scales. Prospective study of consecutive patients attending outpatient services. Both tests were administered by the same researcher on the same day in random order. The total sample (n = 135) was randomly divided into two groups. One to derive a conversion rule (n = 70), and a second (n = 65) in which this rule was tested. The agreement (Pearson's r) of MMSE and MoCA was 0.86 (P < 0.001), and Lin's concordance correlation coefficient (CCC) was 0.57 (95%CI: 0.45-0.66). In the second sample MoCA scores were converted to MMSE scores according to a conversion rule from the first sample which achieved agreement with the original MMSE scores of 0.89 (Pearson's r, P < 0.001) and CCC of 0.88 (95%CI: 0.82-0.92). Although the two scales overlap considerably, the agreement is modest. The conversion rule derived herein demonstrated promising accuracy and warrants further testing in other populations.

    To analyse the evidence concerning the accuracy of the Mini-Mental State Examination (MMSE) as a diagnostic and screening test for the presence of delirium in adults. Two authors searched MEDLINE, PsychINFO and EMBASE from inception till March 2014. Articles were included that investigated the diagnostic validity of the MMSE to detect delirium against standardised criteria. A diagnostic validity meta-analysis was conducted. Thirteen studies were included representing 2017 patients in medical settings of whom 29.4% had delirium. The meta-analysis revealed the MMSE had an overall sensitivity and specificity estimate of 84.1% and 73.0%, but this was 81.1% and 82.8% in a subgroup analysis involving robust high quality studies. Sensitivity was unchanged but specificity was 68.4% (95% CI = 50.9-83.5%) in studies using a predefined cutoff of <24 to signify a case. In high-risk samples where delirium was present in 25% of patients, then the Positive predictive value and Negative predictive value would be 50.9% (48.3-66.2%) and 93.2% (90.0-96.5%). The MMSE cannot be recommended as a case-finding confirmatory test of delirium, but may be used as an initial screen to rule out high scorers who are unlikely to have delirium with approximately 93% accuracy.

    Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson's disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Dementia Rating Scale-2 (DRS-2) have been used extensively for cognitive screening in both clinical and research settings. Determining how to convert the scores between instruments would facilitate the longitudinal assessment of cognition in clinical settings and the comparison and synthesis of cognitive data in multicenter and longitudinal cohort studies. The primary aim of this study was to apply a simple and reliable algorithm for the conversion of MoCA to MMSE scores in PD patients. A secondary aim was to apply this algorithm for the conversion of DRS-2 to both MMSE and MoCA scores. The cognitive performance of a convenience sample of 360 patients with idiopathic PD was assessed by at least two of these cognitive screening instruments. We then developed conversion scores between the MMSE, MoCA, and DRS-2 using equipercentile equating and log-linear smoothing. The conversion score tables reported here enable direct and easy comparison of three routinely used cognitive screening assessments in PD patients. © 2014 International Parkinson and Movement Disorder Society.

    Centenarians represent a rare but rapidly growing segment of the oldest-old. This study presents item-level data from the Mini-Mental State Examination (MMSE) in a cross-sectional, population-based sample of 244 centenarians and near-centenarians (aged 98-108, 16% men, 21% African-American, 38% community dwelling) from the Georgia Centenarian Study (2001-2008) according to age, education, sex, race, and residential status. Multiple-Indicator Multiple-Cause (MIMIC) models were used to identify systematic domain-level differences in MMSE scores according to demographic characteristics in this age group. Indirect effects of age, educational attainment, race, and residential status were found on MMSE scores. Direct effects were limited to concentration for education and race and orientation for residential status. Mean levels of cognitive functioning in centenarians were low, with mean values below most commonly-used cutoffs. Overall scores on the MMSE differed as a function of age, education, race, and residential status, with differences in scale performance limited primarily to concentration and orientation and no evidence of interactions between centenarian characteristics. Adjusting for education was not sufficient to account for differences according to race, and adjusting for residential status was not sufficient to account for differences according to age. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

    Lower levels of cognitive function have been found to be associated with higher mortality in older people, particularly in dementia, but the association in people with other mental disorders is still inconclusive. Data were analysed from a large mental health case register serving a geographic catchment of 1.23 million residents, and associations were investigated between cognitive function measured by the Mini-Mental State Examination (MMSE) and survival in patients aged 65 years old and over. Cox regressions were carried out, adjusting for age, gender, psychiatric diagnosis, ethnicity, marital status, and area-level socioeconomic index. A total of 6,704 subjects were involved, including 3,368 of them having a dementia diagnosis and 3,336 of them with depression or other diagnoses. Descriptive outcomes by Kaplan-Meier curves showed significant differences between those with normal and impaired cognitive function (MMSE scoremental health services regardless of a dementia diagnosis. Causal pathways between this exposure and outcome (for example, suboptimal healthcare) need further investigation.

    The Mini-Mental State Examination (MMSE) is the most widely used cognitive screening test around the world. In Brazil, different MMSE versions and many cut-off points have been used. A systematic review of papers indexed in Scielo was conducted in order to analyze use of the MMSE in Brazilian empirical studies with elderly people. To search for these texts, the complete name of the instrument and its abbreviation were used. A growth trend in the scientific production during the 1998 to 2013 period was observed. Eleven versions of the MMSE were identified and the Bertolucci et al. version was the most cited. Over half of the studies used schooling as the criteria to establish cut-off points. The studies were predominantly conducted using samples recruited from large cities in the Southeastern region and in the community. Despite the growing trend of research with the elderly using the MMSE, the psychometric properties of this scale of measurement have been the subject of little investigation. Despite the widespread use of the MMSE in Brazil, there is a lack of standardization and evidence of validity for this this scale of measurement.

    Although the Mini-Mental State Examination (MMSE) is widely used in clinical practice, normative scores for a healthy population have not been documented in Turkey. The aim in this study was to validate the MMSE in a healthy population and to provide normal scores. Internal construct validity of the Turkish version of MMSE among a preliminary sample of 406 normal people was assessed by Rasch unidimensional measurement model. Scores of the normal sample varied according to age and education but not according to sex. The data derived from this sample showed poor fit to the Rasch model (mean item fit, -2.082, SD 3.022). Only four of 11 items met model expectations. There was also differential item functioning by education and age for most items. Thus the internal construct validity of the Turkish MMSE in a normative sample could not be demonstrated by Rasch analysis. The scale failed modern psychometric criteria for scalability. We would therefore suggest other large normative MMSE data sets to be tested in terms of internal construct validity. If these findings are replicated, the validity of MMSE norms and their consequent use in clinical practice should be reconsidered.

    The aim of the present study was to provide first-hand information about the prevalence of mild cognitive impairment (MCI) and Alzheimer's disease (AD) in Tamil Nadu, a southern state in India, and examine if there exists a relationship between cognitive functions and biochemical parameters in these patients. Surveys were collected from adults, older men and women (n = 3126) from different regions of Tamil Nadu, which were followed up after 12 months for 1337 participants. Mini-Mental State Examination (MMSE) scores, lipid profile, and liver function tests were carried out in the elderly, MCI and AD patients. Based on the MMSE scores, the elderly population was classified into old control (28.97 ± 1.49; n = 1868), MCI (19.58 ± 1.17; n = 734) and AD (7.18 ± 1.38; n = 304) groups. Peripheral blood samples were collected after overnight fast from both male and female volunteers (n = 40 per group) who were categorized as young adult control, old control, MCI and AD. AD patients showed lower MMSE scores compared with the young adults, old and MCI groups, and MMSE further decreased at follow-up examination a year later. In the serum of AD patients, high-density lipoprotein, alkaline phosphatase activity and bilirubin levels were lower, whereas low-density lipoprotein, total cholesterol and triglycerides levels were higher. MMSE was positively correlated with high-density lipoprotein, and negatively correlated with other lipid parameters in AD. Hypercholesterolemia is a risk factor for AD that might result in neurotoxicity and cognitive impairment. Dysfunction of lipoprotein and heme metabolism might also provide additional targets for AD diagnosis. Geriatr Gerontol Int 2017; 17: 1737-1745. © 2016 Japan Geriatrics Society.

    In recent years, the Mini-Mental State Examination (MMSE) has been widely used and has been proposed for cognitive decline screening in the framework of a systematic geriatric evaluation in health centers. The aim of the present longitudinal study was to identify the potential determinants of MMSE score and its evolution over a 4-year period in a population aged over sixty years with good general health without dementia and consulting for a health check-up. Longitudinal study. The preventive medical center (CMP) in Nancy. 687 subjects over 60 years of age (mean age 65.6 ± 5.07 years) were included from the Senior health examination study. All subjects underwent 2 visits over a period of 4 years. MMSE measurement and a self-administered questionnaire of emotional and psychological state were evaluated at baseline and at the follow-up visit. The major components of total variance of baseline MMSE were represented by education level, practice of regular physical activity, nervousness and despair. Multivariate analysis identified 3 variables at baseline visit that independently predicted annual changes in MMSE: MMSE score, education level and "Difficulty in social relations" (r= -0.222, 0.154 and -0.255 respectively). Education level and several psychological factors may influence MMSE score and its evolution over time in community-dwelling subjects aged over 60 years without dementia. In these subjects, a low MMSE score does not predict cognitive decline over a period of 4 years. Therefore, the reliability of MMSE in this type of population is questionable.

    To screen for and determine cognitive dysfunction, cognitive tests and/or informant reports are commonly used. However, these cognitive tests and informant reports are not always available. The present study investigated three screening methods using the Mini-Mental State Examination (MMSE) as the cognitive test, and the Korean dementia screening questionnaire (KDSQ) as the informant report. Participants were recruited from the Korea Clinical Research Center for Dementia of South Korea, and included 2861 patients with Alzheimer's disease (dementia), 3519 patients with mild cognitive impairment and 1375 controls with no cognitive dysfunction. Three screening methods were tested: (i) MMSE alone (MMSE(cut-off) ); (ii) a conventional combination of MMSE and KDSQ (MMSE+KDSQ(cut-off) ); and (iii) a decision tree with MMSE and KDSQ (MMSE+KDSQ(decision tree) ). For discriminating any cognitive dysfunction from controls, MMSE+KDSQ(cut-off) had the highest area under the receiver operating characteristic curve (0.784). For discriminating dementia from controls, MMSE+KDSQ(cut-off) had the highest area under the receiver operating characteristic curve (0.899). For discriminating mild cognitive impairment from controls, MMSE(cut-off) had the highest area under the receiver operating characteristic curve (0.683). MMSE+KDSQ(decision tree) showed the highest sensitivity for all discriminations. For overall classification accuracy, MMSE+KDSQ(decision tree) had the highest value (70.0%). These three methods had different advantageous properties for screening and staging cognitive dysfunction. As there might be different availability across clinical settings, these three methods can be selected and used according to situational needs. © 2015 Japan Geriatrics Society.

  20. Comparison of montreal cognitive assessment and mini-mental state examination in evaluating cognitive domain deficit following aneurysmal subarachnoid haemorrhage.

    Full Text Available Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH, and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa is superior to the Mini-Mental State Examination (MMSE in screening for cognitive domain deficit in aSAH patients.We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2-4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score <-1.65 (below the fifth percentile. Cognitive impairment was defined as two or more cognitive domain deficits. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193.Both the MoCA and the MMSE were successful in differentiating between patients with and without cognitive domain deficits and cognitive impairment at both assessment periods. At 1 year post-ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009.Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases.

    The clinical utility of the Mini-Mental State Examination (MMSE) and its shorter version (SMMSE) is still debated. There is a need to better understand the neuroanatomical correlates of these cognitive tests. The objective of this cross-sectional study was to determine whether lower MMSE and SMMSE scores correlated with focal brain volume reduction in older adults. Participants from the GAIT study (n = 207; mean, 70.9±5.9 years; 57% female; mean MMSE 26.2±3.9; mean SMMSE 5.1±1.1) were evaluated using the MMSE and SMMSE and received a 1.5-Tesla MRI scan of the brain. Cortical gray and white matter subvolumes were automatically segmented using Statistical Parametric Mapping. Age, gender, education level, and total intracranial volume were included as potential confounders. We found correlations between the MMSE score and specific cortical regions of the limbic system including the hippocampus, amygdala, cingulate gyrus, and parahippocampal gyrus, independently of the diagnostic category (i.e., mild cognitive impairment or Alzheimer disease or controls). Regarding correlations with the SMMSE score, only one cluster in the left hippocampus was identified, which overlapped with the cluster that was positively correlated with the MMSE score. There were no correlations with the volume of white matter. In conclusion, worse MMSE and SMMSE scores were associated with gray matter atrophy mainly in the limbic system. This finding highlights that atrophy of specific brain regions are related to performance on the MMSE and the SMMSE tests, and provides new insights into the cognitive function probed by these tests.

    The present prospective study used repeated measures analysis to identify potential Mini-Mental State Examination (MMSE) score trajectories and determine whether MMSE trajectory was associated with incident disabling dementia among community-dwelling older Japanese adults. A total of 1724 non-demented adults (mean age 71.4 years [SD 5.7]; 56.7% women) aged 65-90 years participated in annual geriatric health assessments during the period from June 2002 through July 2014. The total number of observations was 6755, and the average number of follow-up assessments was 3.9. A review of municipal databases in the Japanese public long-term care insurance system showed that 205 (11.9%) participants developed disabling dementia through December 2014. We identified three distinct MMSE score trajectory patterns (high, middle and low) in adults aged 65-90 years. After adjusting for important confounders, participants with middle (42.8%) and low (5.1%) MMSE trajectories had hazard ratios of 2.46 (95% confidence interval 1.64-3.68) and 10.73 (95% confidence interval 4.91-23.45), respectively, for incident disabling dementia, as compared with those in the high (52.1%) trajectory group. Approximately half of the participants were classified as having a high MMSE trajectory, whereas 43% and 5% had middle and low MMSE trajectories, respectively, in this population. Individuals with middle and low MMSE trajectories had a higher risk for incident disabling dementia, which suggests that a high-risk approach to dementia prevention should target people with mild and more rapid cognitive decline.

    The objective of this study is to validate two abridged versions of the mini-mental state examination (MMSE): one intended for use in face-to-face interviews, and the other developed for telephonic interviews, using data from Sweden and the US to validate the abridged scales against dementia diagnoses as well as to compare their performance to that of the full MMSE scale. The abridged versions were based on eight domains from the original MMSE scale. The domains included in the MMSE-SF were registration, orientation, delayed recall, attention, and visual spatial ability. In the MMSE-SF-C, the visual spatial ability item was excluded, and instead, one additional orientation item was added. There were 794 participants from the Swedish HARMONY study [mean age 81.8 (4.8); the proportion of cognitively impaired was 51 %] and 576 participants from the US ADAMS study [mean age 83.2 (5.7); the proportion of cognitively impaired was 65 %] where it was possible to compare abridged MMSE scales to dementia diagnoses and to the full MMSE scale. We estimated the sensitivity and specificity levels of the abridged tests, using clinical diagnoses as reference. Analyses with both the HARMONY and the ADAMS data indicated comparable levels of sensitivity and specificity in detecting cognitive impairment for the two abridged scales relative to the full MMSE. Receiver operating characteristic curves indicated that the two abridged scales corresponded well to those of the full MMSE. The two abridged tests have adequate validity and correspond well with the full MMSE. The abridged versions could therefore be alternatives to consider in larger population studies where interview length is restricted, and the respondent burden is high.

    To investigate whether demographic (age and education) adjustments for the Mini-Mental State Examination (MMSE) attenuate mean score discrepancies between African-American and Caucasian adults and whether demographically adjusted MMSE scores improve the diagnostic classification accuracy of dementia in African-American adults over unadjusted MMSE scores. Cross-sectional study. Community-dwelling adults participating in the Mayo Clinic Alzheimer's Disease Patient Registry and Alzheimer's Disease Research Center. Three thousand two hundred fifty-four adults (2,819 Caucasian, 435 African American) aged 60 and older. MMSE score at study entry. African-American adults had significantly lower unadjusted MMSE scores (23.0 ± 7.4) than Caucasian adults (25.3 ± 5.4). This discrepancy persisted despite adjustment of MMSE scores for age and years of education using established regression weights or newly derived weights. Controlling for dementia severity at baseline and adjusting MMSE scores for age and quality of education attenuated this discrepancy. In African-American adults, an age- and education-adjusted MMSE cut score of 23/24 provided optimal dementia classification accuracy, but this represented only a modest improvement over an unadjusted MMSE cut score of 22/23. The posterior probability of dementia in African-American adults is presented for various unadjusted MMSE cut scores and prevalence rates of dementia. Age, dementia severity at study entry, and quality of educational experience are important explanatory factors in understanding the existing discrepancies in MMSE performance between Caucasian and African-American adults. These findings support the use of unadjusted MMSE scores when screening older African Americans for dementia, with an unadjusted MMSE cut score of 22/23 yielding optimal classification accuracy. © 2012, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

    The minimental state examination (MMSE) is a widely used, standardized method to assess cognitive function including movement-related disorders with high reliability. We studied the relationship between MMSE scores and the ability to take oral medications correctly (ingestion compliance) in 70 elderly inpatients (mean age 71.3+/-7.0 years). Patients with abnormal glucose tolerance as determined by an HbA(1c) level of 5.8% or greater including diabetes showed a trend of lower MMSE scores compared with patients with normal glucose tolerance, and the scores were negatively correlated with HbA1c, age, and systolic blood pressure (P<0.05). Self-management in taking oral medications was very difficult in 4 patients whose MMSE scores were 21 points or less. Thus ingestion supervisions by nurses were required in these patients. Furthermore, 9 of 12 noncompliant patients had MMSE scores ranging from 22 to 26 points. We instructed these patients to take medications in a one-dose package as a useful tool to improve compliance. The MMSE score was 27 or higher in 44 of 54 compliant patients, and 10 patients had scores ranging from 21 to 26. The sensitivity and specificity for noncompliance at an MMSE score cut-off point of 26 were 75.0% and 81.5%, respectively. In conclusion, it is necessary to coordinate ingestion methods matched to each patient according to their abilities to comply with medication schedules. They should be preevaluated with the MMSE to improve ingestion compliance. The MMSE is a recommended test in hospitalized elderly patients for the assessment of the ability to take medications safely.

    To compare Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) global and subscores in classifying cognitive impairment in persons with mild stroke and to explore the relationship between admission and discharge functional status and improvement. Retrospective analysis of data. Acute rehabilitation unit of a large urban university-affiliated hospital. Inpatients with stroke (N=72; mean age, 70y; median time poststroke, 8.5d) and mild neurologic (median National Institutes of Health Stroke Scale score, 4) and cognitive deficits (median MMSE score, 25). Not applicable. Admission cognitive status was assessed by using the MMSE and MoCA. The motor subscale of the FIM instrument (mFIM) and motor relative functional efficiency was used to assess discharge functional status and improvement. The MoCA classified more persons as cognitively impaired than the MMSE (89% vs 63%, respectively; using a cutoff score of 27 on the MMSE and 26 on the MoCA). The MoCA also showed less of a ceiling effect than the MMSE, higher internal reliability (Cronbach α=.78 compared with α=.60), and marginally stronger associations with discharge functional status (r=.40; P<.001) than the MMSE (r=0.30; P<.05). The MoCA visuoexecutive subscore was the strongest predictor of functional status (P=.01) and improvement (P=.02) in global and subscores for both tests. The MoCA may be an important cognitive screening tool for persons with stroke and mild cognitive dysfunction on an acute rehabilitation unit. Lower visuoexecutive subscores may assist in identifying persons at risk for decreased functional gains in self-care and mobility (mFIM) during inpatient rehabilitation. The findings justify further validation studies of the MoCA in persons with subacute stroke. Copyright © 2011 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    Recent publications have highlighted the low sensitivity of the Mini-Mental State Examination (MMSE) for the cognitive assessment of patients with Parkinson disease (PD). The Montreal Cognitive Assessment (MoCA), otherwise, has shown greater sensitivity when compared to the MMSE. Based on this, we have searched for the cognitive impairment measurable by the MoCA and the functional performance on activities of daily living in a sample of Brazilian patients with PD and normal MMSE. We hypothesized that the low sensitivity of the MMSE, already shown by other authors, could be replicated in a low-income country. To describe the performance on the MoCA and the dependence on third parties for activities of daily living in a sample of Brazilian patients with PD and normal MMSE. We evaluated 43 volunteers with PD and normal MMSE considering the Brazilian cutoffs. Cognitive performance was assessed through the MoCA and functional performance through a modified version of the Disability Assessment for Dementia Scale. Despite normal score on the MMSE, considering the Brazilian cutoffs, 62.7% of the volunteers performed below the literature cutoff for the MoCA (26 points). Furthermore, 30.2% had dependence on third party for activities of daily living. By using a strict cutoff for the MMSE (26 points), 56.7% performed below the MoCA cutoff and 24.3% had dependence for activities of daily living. Our findings confirm the limitations of the MMSE for the cognitive screening of patients with PD in a low-income country.

    To describe the relationship of Mini-Mental State Exam (MMSE) scores and changes over time in MMSE scores to age and education in a population of older women. A prospective study of a defined population. Various motherhouses and church-run health care facilities in the Eastern, Midwestern, and Southern regions of the United States. Catholic sisters (nuns) participating in the Nun Study, a study of aging and Alzheimer's Disease. The 678 participants were 75 to 102 years old (mean 83.3, standard deviation 5.5, median 82.3) at the time of the first functional assessment. Second assessments were obtained an average of 1.6 years later on 575 survivors. The outcome variables were MMSE scores at the first assessment (Time-one), and MMSE scores at the second assessment (Time-two). The independent variables were age at Time-one, and education (bachelor's degree or no bachelor's degree). Time-one MMSE scores decreased with age at Time-one. The decrease in MMSE scores with age was less in sisters with bachelor's degrees than in sisters without bachelor's degrees. The changes in MMSE scores had a "U-shaped" relationship with Time-one score, where the greatest declines occurred in sisters with intermediate Time-one scores. Stratified analysis by age, education, and Time-one MMSE scores of 20 or greater because of the small numbers of sisters with Time-one scores less than 20. In sisters with Time-one MMSE scores in the categories 20 to 23, 24 to 26, or 27 to 30, older ages at Time-one were associated with greater decline in those with bachelor's degrees, but not in those without bachelor's degrees. Also, lower education was associated with greater decline in sisters aged 75 to 84 years at Time-one, but this education effect disappeared or reversed in sisters who were 85 years of age or older at Time-one. Cognitive function as measured by the MMSE decreased with age at Time-one, most steeply as a function of age in those without bachelor's degrees. Cognitive function declined

    Polychlorinated biphenyls (PCB)/polychlorinated dibenzofurans (PCDF) are known to affect central nervous functioning. In recent studies, elderly patients who have been exposed to these have been noted to have psychological deficits. There is little known about which test is sensitive to neurotoxins in cognitive evaluation. The objective of the present study was to compare the significance between selective psychological tests in cognitive assessment in PCB-laden elderly. A retrospective PCB/PCDF exposed cohort was observed. Exposed elderly aged ≥ 60 years and registered in Central Health Administration were enrolled, and similar age- and sex-matched subjects served as non-exposed controls. The Mini-Mental State Examination (MMSE) and Attention and Digit Span (ADS) were tested in both groups. Student's t-test, χ(2) -test and linear regression models were used for statistical analysis.  A total of 165 exposed patients and 151 controls were analyzed. The exposed group included 49% men, a mean age of 69.3 ± 6.4 years and an education level of 4.0 ± 3.9 years. The controls included 52% men, a mean age of 69.9 ± 5.5 years and an education level of 4.5 ± 3.2 years. There was no statistical difference in MMSE before and after adjusting for the confounding variables of age, sex and education (P= 0.16 vs P= 0.12). However, ADS-forward and ADS-total scores showed a significant decline in the exposed subjects (P= 0.0001 vs P= 0.001). Using a linear regression among stratified PCB and cognitive functioning (≤30 ppb; 31-89; ≥90), a dose effect was found at the medium (31-89 ppb) and high exposure (≧90 ppb) levels. Our observations showed attention and short-term memory were impaired in PCB-laden elderly patients. Higher exposure level showed lower cognitive functioning in ADS. The MMSE was insensitive to neurotoxins. The present study shows that the selective test has a decisive role in toxic-related cognitive assessments. © 2010 The Authors. Psychogeriatrics

    To explore the optimal cutoff score for initial detection of Alzheimer's Disease (AD) through the Chinese version of Mini-Mental State Examination (CMMSE) in rural areas in China, we conducted a cross-sectional study within the Linxian General Population Nutritional Follow-up study. 16,488 eligible cohort members participated in the survey and 881 completed the CMMSE. Among 881 participants, the median age (Interquartile range) was 69.00 (10.00), 634 (71.92%) were female, 657 (74.57%) were illiterate, 35 (3.97%) had 6 years of education or higher, and 295 (33.48%) were diagnosed with AD. By reducing the CMMSE criteria for illiterate to 16 points, primary school to 19 points, and middle school or higher to 23 points, the efficiency of Chinese version of Mini-Mental State Examination can be significantly improved for initial detection of AD in rural areas in China, especially in those nutrition deficient areas. © The Author(s) 2016.

    Full Text Available Abstract Background We assessed whether the Korean version of modified Mini-Mental State Examination (K-mMMSE has improved performance as a screening test for cognitive impairment or dementia in a general population compared with the Korean Mini-Mental State Examination (K-MMSE. Methods Screening interviews were conducted with people aged 65 and over in Noam-dong, Namwon-city, Jeonbuk province. There were 522 community participants, of whom 235 underwent clinical and neuropsychological examination for diagnosis of dementia and Cognitive Impairment No Dementia (CIND. Sensitivity, specificity and areas under the receiver operating characteristic (ROC curves for the K-mMMSE and the K-MMSE were the main outcome measures. Results Cronbach's alpha for the K-mMMSE was 0.91, compared with 0.84 for the K-MMSE. The areas under the ROC curves in identifying all levels of CIND or dementia were 0.91 for the K-mMMSE and 0.89 for the K-MMSE (P r = 0.89. Conclusion Our findings indicate that the K-mMMSE is more reliable and valid than the K-MMSE as a cognitive screen in a population based study of dementia. Considering the test characteristics, the K-MMSE and modified version are expected to be optimally used in clinical and epidemiologic fields.

    As the population ages, there is a growing need to quickly and accurately identify putative dementia cases. Many cognitive tests are available; among those commonly used are the Cognitive Dementia Rating (CDR) and the Mini-Mental Status Examination (MMSE). The aim of this work was to compare the validity and reliability of these cognitive tests in a primary care based cohort (pcb-Cohort). The MMSE and the CDR were applied to 568 volunteers in the pcb-Cohort. Distinct cut-off points for the MMSE were considered, namely MMSE 27, MMSE 24, and MMSE PT (adapted for the Portuguese population). The MMSE 27 identified the greatest number of putative dementia cases, and, as determined by the ROC curve, it was the most sensitive and specific of the MMSE cut-offs considered. Putative predictive or risk factors identified included age, literacy, depression, and diabetes mellitus (DM). DM has previously been indicated as a risk factor for dementia and Alzheimer's disease. Comparatively, the MMSE 27 cut-off has the greatest sensibility (94.9%) and specificity (66.3%) when compared to MMSE PT and MMSE 24. Upon comparing MMSE and CDR scores, the latter identified a further 146 putative dementia cases, thus permitting one to propose that in an ideal situation, both tests should be employed. This increases the likelihood of identifying putative dementia cases for subsequent follow up work, thus these cognitive tests represent important tools in patient care. Further, this is a significant study for Portuguese populations, where few of these studies have been carried out.

    This study was conducted to estimate screening performance of dementia screening tools including Mini-Mental State Examination (MMSE), Mini-Cog, Clock Drawing Test (CDT) and Ascertain Dementia 8 questionnaire (AD8) for older adults. 2015 participants aged 65 years or more in eastern China were enrolled. 4 screening tests were administered and scored by specifically trained psychiatrists. We used data from two-by-two tables to calculate the sensitivity, specificity, and positive and negative predictive values (PPV/NPV). Our study showed that dementia was highly prevalent among elderly in Zhejiang province. The Mini-Cog, with excellent screening characteristics and spending less time, could be considered to be used as a screening tool among communities to help to diagnose dementia early.

    The aim of this single photon emission computed tomography (SPECT) study was to determine the abnormality of the regional cerebral blood flow (rCBF), using a three-dimensional stereotactic surface projection (3D-SSP), in 18 patients referred to the hospital due to forgetfulness. An intergroup comparison, by 3D-SSP analysis, was conducted based on Mini-Mental State Examination (MMSE) results of the total score, time orientation, place orientation, recall, serial sevens and figure copy. In each abnormal group, rCBF was partially decreased in the temporo-parietal cortex, medial temporal structure and posterior cingulate gyrus; these areas with decreased rCBF are similar to the pattern found in Alzheimer's disease. In the abnormal group, at the time of orientation and figure copy, rCBF was decreased in the right parieto-occipital area. (author)

    Presence of detailed screening instruments to detect cognitive impairment in the older adults' culture and language is very essential. The Saint Louis University Mental Status Examination (SLUMS) is one of cognitive screening scales used. The aim of the study was to establish the validity and reliability of the Turkish version of SLUMS (SLUMS-T). Two hundred seventy-four participants aged 60 years and older admitted to our geriatric clinic were screened for cognitive impairment using SLUMS-T and Mini-Mental State Examination. Internal consistency was analyzed with Cronbach α test. Area under curves of receiver operating characteristic analyses were used to test the predictive accuracy of the SLUMS-T for detecting amnestic mild cognitive impairment (aMCI) and Alzheimer disease (AD) to set an appropriate cut-off point. The SLUMS-T scores were positively correlated with the Mini-Mental State Examination scores of the patients with aMCI and patients with AD and controls (r = 0.687, P < .001; r = 0.880, P < .001; respectively). Internal consistency of the SLUMS-T was Cronbach α = 0.85. It was found that SLUMS-T with a cut-off point of 23 had a sensitivity of 66.6% and a specificity of 72.3% for the diagnosis of aMCI, and with a cut-off point of 20 had a sensitivity of 83.8% and a specificity of 87.3% for the diagnosis of AD. SLUMS-T was demonstrated to have sufficient validity and reliability to evaluate cognitive impairment including MCI among Turkish elderly people.

    To determine if there is an association between hearing loss and poorer cognitive scores on Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) and to determine if poor hearing acuity affects scoring on the cognitive screening tests of MMSE and MoCA. One hundred fourteen elderly patients (Singapore residents) aged between 55 and 86 years were sampled. Participants completed a brief history questionnaire, pure tone audiometry, and 2 cognitive screening tests-the MMSE and MoCA. Average hearing thresholds of the better ear in the frequencies of 0.5, 1, 2, and 4 kHz were used for data analysis. Hearing loss was significantly associated with poorer cognitive scores in Poisson regression models adjusted for age. Mini-Mental State Examination scores were shown to decrease by 2.8% (P = .029), and MoCA scores by 3.5% (P = .013) for every 10 dB of hearing loss. Analysis of hearing-sensitive components of "Registration" and "Recall" in MMSE and MoCA using chi-square tests showed significantly poorer performance in the hearing loss group as compared to the normal hearing group. Phonetic analysis of target words with high error rates shows that the poor performance was likely contributed by decreased hearing acuity, on top of a possible true deficit in cognition in the hearing impaired. Hearing loss is associated with poorer cognitive scores on MMSE and MoCA, and cognitive scoring is likely confounded by poor hearing ability. This highlights an important, often overlooked aspect of sensory impairment during cognitive screening. Provisions should be made when testing for cognition in the hearing-impaired population to avoid over-referral and subsequent misdiagnoses of cognitive impairment.

A variety of medications, including herbal preparations (in particular Ginkgo biloba and Panax ginseng, have been advocated as treatments for cognitive impairment in the elderly. In this study, we investigated the effect of an already marketed dietary supplement (Memo® combining 750 mg of lyophilized royal jelly with standardized extracts of G. biloba 120 mg and P. ginseng 150 mg on Mini-Mental State Examination (MMSE scores in patients with mild cognitive impairment. Methods: Sixty-six subjects presenting with forgetfulness and satisfying the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR clinical criteria for mild cognitive impairment were randomly divided into an experimental group treated with one Memo capsule before breakfast daily for 4 weeks and a control group who took placebo. The mean change in MMSE score from baseline and reported adverse effects were compared between the two groups. Results: The mean change in MMSE score in the group treated with Memo for 4 weeks was significantly greater than in the control group (+2.07 versus +0.13, respectively by the Student’s t-test (t = 6.485, P < 0.0001. This was also true after adjusting for age as a covariate and educational level as a factor nested within the treatment groups in a general linear model (analysis of covariance, F = 9.675 [corrected model], P < 0.0001. Conclusion: This combined triple formula may be beneficial in treating the cognitive decline that occurs during the aging process as well as in the early phases of pathologic cognitive impairment typical of insidious-onset vascular dementia and in the early stages of Alzheimer’s disease.

    To validate the Mini-Mental State Examination (MMSE) Telephone (MMSET) against the MMSE. Cross-sectional. Homes of community-dwelling older adults. African-American and non-Hispanic white adults aged 75 and older participating in the University of Alabama at Birmingham Study of Aging II, a longitudinal epidemiological study across the state of Alabama (N = 419). Cognition, measured using the MMSE, MMSET, and Six-Item Screener (SIS), and function, based on self-reported difficulty performing instrumental activities of daily living (IADLs). Correlation and agreement coefficients were used to examine concordance of the MMSE and MMSET; linear and logistic regressions were used to test associations with clinical outcomes of IADL difficulty and verified diagnoses of dementia. The MMSET showed good internal consistency (Cronbach α = 0.845), similar to the full MMSE, and strong correlation with the latter (Spearman ρ = 0.694, P < .001). The MMSET explained a similar proportion of IADL difficulty as the full MMSE (coefficient of variation = 0.201 and 0.189, respectively). The MMSET was also associated with verified dementia diagnoses (area under the receiver operating characteristic curve = 0.73), which was similar to the full MMSE. The MMSET is a brief, valid measure of cognition in older adults with psychometric properties similar to that of the full MMSE. Because it can be administered over the telephone, further use in epidemiological studies is promising. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Performance on the Mini-Mental State Examination (MMSE), among the most widely used global screens of adult cognitive status, is affected by demographic variables including age, education, and ethnicity. This study extends prior research by examining the specific effects of bilingualism on MMSE performance. Sixty independent community-dwelling monolingual and bilingual adults were recruited from eastern and western regions of the United States in this cross-sectional group study. Independent sample t tests were used to compare 2 bilingual groups (Spanish-English and Asian Indian-English) with matched monolingual speakers on the MMSE, demographically adjusted MMSE scores, MMSE item scores, and a nonverbal cognitive measure. Regression analyses were also performed to determine whether language proficiency predicted MMSE performance in both groups of bilingual speakers. Group differences were evident on the MMSE, on demographically adjusted MMSE scores, and on a small subset of individual MMSE items. Scores on a standardized screen of language proficiency predicted a significant proportion of the variance in the MMSE scores of both bilingual groups. Bilingual speakers demonstrated distinct performance profiles on the MMSE. Results suggest that supplementing the MMSE with a language screen, administering a nonverbal measure, and/or evaluating item-based patterns of performance may assist with test interpretation for this population.

    The Mini-Mental State Examination (MMSE) is considered a useful supplementary method to diagnose dementia and evaluate the severity of cognitive disturbance. However, the region of the cerebrum that correlates with the MMSE score is not clear. Recently, a new method was developed to analyze regional cerebral blood flow (rCBF) using a Z score imaging system (eZIS). This system shows changes of rCBF when compared with a normal database. In addition, a three-dimensional stereotaxic region of interest (ROI) template (3DSRT), fully automated ROI analysis software was developed. The objective of this study was to investigate the correlation between rCBF changes and total MMSE score using these new methods. The association between total MMSE score and rCBF changes was investigated in 24 patients (mean age±standard deviation (SD) 71.5±9.2 years; 6 men and 18 women) with memory impairment using eZIS and 3DSRT. Step-wise multiple regression analysis was used for multivariate analysis, with the total MMSE score as the dependent variable and rCBF change in 24 areas as the independent variable. Total MMSE score was significantly correlated only with the reduction of left hippocampal perfusion but not with right (P<0.01). Total MMSE score is an important indicator of left hippocampal function. (author)

    Despite the considerable prevalence of cognitive impairment in substance-using populations, there has been little investigation of the utility of cognitive screening measures within this context. In the present study the accuracy of three cognitive screening measures in this population was examined-the Mini-Mental State Examination (MMSE), the Addenbrooke's Cognitive Examination-Revised (ACE-R), and the Montreal Cognitive Assessment (MoCA). A sample of 30 treatment-seeking substance users and 20 healthy individuals living in the community were administered the screening measures and a neuropsychological battery (NPB). Agreement of classification of cognitive impairment by the screening measures and NPB was examined. Results indicated that the ACE-R and MoCA had good discriminative ability in detection of cognitive impairment, with areas under the receiver-operating characteristic (ROC) curve of .85 (95% confidence interval, CI [.75. .94] and .84 (95% CI [.71, .93]) respectively. The MMSE had fair discriminative ability (.78, 95% CI [.65, .93]). The optimal cut-score for the ACE-R was 93 (impairment = score of 92 or less), at which it correctly classified 89% of individuals as cognitively impaired or intact, while the optimal cut-score for the MoCA was cognitive impairment in the context of substance use.

    The conventional practice of assessing cognitive status and monitoring change over time in older adults using normative values of the Mini-Mental State Exam (MMSE) based on age bands is imprecise. Moreover, population-based normative data on changes in MMSE score over time are scarce and crude because they do not include age- and education-specific norms. This study aims to develop unconditional standards for assessing current cognitive status and conditional standards that take prior MMSE score into account for assessing longitudinal change, with percentile curves as smooth functions of age. Cross-sectional and longitudinal data of a modified version of the MMSE for 2,026 older Chinese adults from the Singapore Longitudinal Aging Study, aged 55-84, in Singapore were used to estimate quantile regression coefficients and create unconditional standards and conditional standards. We presented MMSE percentile curves as a smooth function of age in education strata, for unconditional and conditional standards, based on quantile regression coefficient estimates. We found the 5th and 10th percentiles were more strongly associated with age and education than were higher percentiles. Model diagnostics demonstrated the accuracy of the standards. The development and use of unconditional and conditional standards should facilitate cognitive assessment in clinical practice and deserve further studies.

    THIS STUDY AIMED TO INVESTIGATE WHETHER THE SUPPLEMENTATION OF VERBAL FLUENCY: Animal category test (VF) performance can improve the screening ability of Mini-Mental State Examination (MMSE) for mild cognitive impairment (MCI), dementia and their major subtypes. Six hundred fifty-five cognitively normal (CN), 366 MCI [282 amnestic MCI (aMCI); 84 non-amnestic MCI (naMCI)] and 494 dementia [346 Alzheimer's disease (AD); and 148 non-Alzheimer's disease dementia (NAD)] individuals living in the community were included (all aged 50 years and older) in the study. The VF-supplemented MMSE (MMSE+VF) score had a significantly better screening ability for MCI, dementia and overall cognitive impairment (MCI plus dementia) than the MMSE raw score alone. MMSE+VF showed a significantly better ability than MMSE for both MCI subtypes, i.e., aMCI and naMCI. In the case of dementia subtypes, MMSE+VF was better than the MMSE alone for NAD screening, but not for AD screening. The results support the usefulness of VF-supplementation to improve the screening performance of MMSE for MCI and NAD.

    Studies have found that age and education were associated with cognition in older adults. However, little is known how clinical factors (e.g. age of illness onset, length of hospital stay, type of antipsychotic medications, and duration of illness) are associated with cognitive functioning in patients with schizophrenia. This study aimed to examine the influence of socio-demographic and clinical factors on cognitive domains measured using Mini-Mental State Examination (MMSE) among patients with schizophrenia or schizoaffective disorders residing in a psychiatric institute in Singapore. A single-phase interview was conducted at the Institute of Mental Health (IMH) in patients diagnosed with schizophrenia or schizoaffective disorders (n=110). MMSE was administered to all participants. Data on socio-demographic characteristics, smoking, alcohol consumption, and medical history were collected. Age, gender, and level of education were significantly associated with MMSE scores. After adjusting for all socio-demographic correlates, longer length of hospital stay remained significant in predicting lower MMSE scores. Length of hospital stay was independently associated with cognitive functioning. Early interventions for cognition such as physical and mental exercises should be implemented for better prognosis.

    To provide a crosswalk between the recently proposed short Montreal Cognitive Assessment (s-MoCA) and Mini-Mental State Examination (MMSE) within a clinical cohort. A total of 791 participants, with and without neurologic conditions, received both the MMSE and the MoCA at the same visit. s-MoCA scores were calculated and equipercentile equating was used to create a crosswalk between the s-MoCA and MMSE. As expected, s-MoCA scores were highly correlated (Pearson r = 0.82, P < .001) with MMSE scores. s-MoCA scores correctly classified 85% of healthy older adults and 91% of individuals with neurologic conditions that impair cognition. In addition, we provide an easy to use table that enables the conversion of s-MoCA score to MMSE score. The s-MoCA is quick to administer, provides high sensitivity and specificity for cognitive impairment, and now can be compared directly with the MMSE. Copyright © 2017 the Alzheimer's Association.

    The aim of this study was to assess the specificities of the Mini-Cog, the Clock Drawing Test (CDT), and the Mini-Mental State Examination (MMSE) against depression and healthy controls in a German Memory Clinic. Furthermore, we analyzed the specificities of all three screening instruments in dependence of actual depression severity. Data from 142 depressed elderly, 438 dementia patients, and 64 healthy controls were retrospectively analyzed. The CDT and an extraction of the three-item recall of the MMSE were used to constitute the Mini-Cog algorithm. Depression severity was rated by either the Beck Depression Inventory (BDI) or the Geriatric Depression Scale (GDS) depending on the age of the patients. The Mini-Cog achieved a specificity of 79.6% against depressed elderly and 100.0% against healthy subjects (p Mini-Cog and the CDT, but also showed the lowest sensitivity for the detection of dementia. Surprisingly, the depression severity had no effect on the specificity of the Mini-Cog and the CDT, only the MMSE was susceptible for the depression severity. Although the MMSE showed higher specificities, the weighting between the sensitivities and specificities in all tests prove again the Mini-Cog as a short, valid, and sensitive screening tool.

    In diagnostics of Alzheimer's disease (AD), the Mini-Mental State Examination (MMSE) questionnaire is frequently used to test cognitive decline. The final subtest of the MMSE, in which patients have to copy two interlocking pentagons, tests a variety of visuomotor functions. Recent imaging studies suggest that visuomotor function could decline in early stage AD, as a result of degeneration of the brain networks involved. The goal of the present study was to compare memory and visuomotor function in AD patients, reflected by the MMSE subscores for orientation, recall and interlocking pentagons. The MMSE subscores for orientation, recall and interlocking pentagons of 125 AD patients was extracted from their medical history. Patients were divided into three groups based on disease duration. Using related-samples Wilcoxon signed-rank tests, the performance between subtests using normalized subscores was compared within each group. In all three groups, the subscores of recall and interlocking pentagons were significantly lower than orientation. No differences were found between the subscores of recall and interlocking pentagons. The presented data suggest that memory function and visuomotor function are equally impaired in the present study population. This could indicate that visuomotor dysfunction might be a more important clinical feature of AD than is currently assumed. This knowledge can be used to develop new tests and markers for AD reflecting deficits in visuomotor functions, such as quantification of eye and hand movements. © 2013 Japan Geriatrics Society.

    Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson’s disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Dementia Rating Scale-2 (DRS-2) have been used extensively for cognitive screening in both clinical and research settings. Determining how to convert the scores between instruments would facilitate the longitudinal assessment of cognition in clinical settings and the comparison and synthesis of cognitive data in multicenter and longitudinal cohort studies. The primary aim of this study was to apply a simple and reliable algorithm for the conversion of MoCA to MMSE scores in PD patients. A secondary aim was to apply this algorithm for the conversion of DRS-2 to both MMSE and MoCA scores. The cognitive performance of a convenience sample of 360 patients with idiopathic PD was assessed by at least two of these cognitive screening instruments. We then developed conversion scores between the MMSE, MoCA, and DRS-2 using equipercentile equating and log-linear smoothing. The conversion score tables reported here enable direct and easy comparison of three routinely used cognitive screening assessments in PD patients. PMID:25381961

    Two conversion tables between the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) have recently been established for Parkinson's disease (PD). This study aimed to validate them in Korean patients with PD and to evaluate whether they could be influenced by educational level. A total of 391 patients with PD who undertook both the Korean MMSE and the Korean MoCA during the same session were retrospectively assessed. The mean, median, and root mean squared error (RMSE) of the difference between the true and converted MMSE scores and the intraclass correlation coefficient (ICC) were calculated according to educational level (6 or fewer years, 7-12 years, or 13 or more years). Both conversions had a median value of 0, with a small mean and RMSE of differences, and a high correlation between the true and converted MMSE scores. In the classification according to educational level, all groups had roughly similar values of the median, mean, RMSE, and ICC both within and between the conversions. Our findings suggest that both MMSE-MoCA conversion tables are useful instruments for transforming MoCA scores into converted MMSE scores in Korean patients with PD, regardless of educational level. These will greatly enhance the utility of the existing cognitive data from the Korean PD population in clinical and research settings.

    To examine level of and change in cognitive status using the Mini-Mental State Examination (MMSE) in relation to dementia, mortality, education, and sex in late nonagenarians. Three-year longitudinal study with examinations at ages 97, 99, and 100. Trained psychiatric research nurses examined participants at their place of living. A representative population-based sample of 97-year-old Swedes (N = 591; 107 men, 484 women) living in Gothenburg, Sweden. A Swedish version of the MMSE was used to measure cognitive status. Geriatric psychiatrists diagnosed dementia according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. Mixed models were fitted to the data to model the longitudinal relationship between MMSE score and explanatory variables. Individuals with dementia between age 97 and 100 had lower mean MMSE scores than those without dementia. Those who died during the 3-year follow-up had lower MMSE scores than those who survived. MMSE scores at baseline did not differ between those without dementia and those who developed dementia during the 3-year follow-up. Participants with more education had higher MMSE scores, but there was no association between education and linear change. MMSE score is associated with dementia and subsequent mortality even in very old individuals, although the preclinical phase of dementia may be short in older age. Level of education is positively associated with MMSE score but not rate of decline in individuals approaching age 100. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    The aim of this single photon emission computed tomography (SPECT) study was to determine the abnormality of the regional cerebral blood flow (rCBF) using a three-dimensional stereotactic surface projection (3D-SSP) in 18 patients who were referred to the hospital because of forgetfulness. Two intergroup comparison by 3D-SSP analysis was conducted based on MRI, kana pick-out test and Mini-Mental State Examination (MMSE) results. Of the MRI findings, in the brain atrophy group, rCBF was decreased in the posterior cingulate gyrus, medial temporal structure and parieto-temporal association cortex; these rCBF-decreased areas are similar to the Alzheimer disease pattern. In the group where the MMSE was normal but the kana pick-out test was abnormal, rCBF was decreased in the posterior cingulate gyrus and cinguloparietal transitional area. In the group where both the MMSE and kana pick-out test were abnormal, rCBF was decreased in the parieto-temporal association cortex, temporal cortex and medial temporal structure. These results suggest that 3D-SSP analysis of the SPECT with MMSE and the kana pick-out test provides the possibility of early diagnosis of initial stage of Alzheimer's disease. (author)

    Dementia is one of the leading causes of dependence in the elderly. This study was conducted to estimate diagnostic performance of dementia screening tests including Mini-Mental State Examination (MMSE), Mini-Cog, Clock Drawing Test (CDT) and Ascertain Dementia 8 questionnaire (AD8) by Bayesian models. A total of 2015 participants aged 65 years or more in eastern China were enrolled. The four screening tests were administered and scored by specifically trained psychiatrists. The prior information of sensitivity and specificity of every screening test was updated via Bayes' theorem to a posterior distribution. Then the results were compared with the estimation based on National Institute of Aging-Alzheimer's Association criteria (NIA-AA). The diagnostic characteristics of Mini-Cog, including sensitivity, specificity, PPV, NPV, especially the Youden index, performed well, even better than the combinations of several screening tests. The Mini-Cog with excellent screening characteristics, spending less time, could be considered to be used as a screening test to help to screen patients with cognitive impairment or dementia early. And Bayesian method was shown to be a suitable tool for evaluating dementia screening tests.

    To review systematically studies investigating the convergent, criterion, and predictive validity of multi-domain cognitive screening instruments in the first four weeks after stroke. Electronic databases (Pubmed, PsycINFO, CINAHL, Embase) were searched until June 2014. Studies concerning screening for cognitive dysfunction in stroke patients using multi-domain instruments, within four weeks postinfarct or haemorrhagic stroke, using tests taking no longer than one hour. Convergent, criterion, and predictive validity were examined. A total of 51 studies investigating 16 cognitive screening instruments were identified. None of the instruments covered all of the most affected cognitive domains. Only one study investigated the convergent validity of a multi-domain test during the (sub)acute phase after stroke. A total of 15 studies examined the criterion validity of cognitive measurements during the acute phase after stroke. The Montreal Cognitive Assessment and Higher Cortical Function Deficit Test had good criterion validity. A total of 24 studies examined the predictive ability of multi-domain cognitive instruments applied in the acute phase after stroke. The Cognistat, Montreal Cognitive Assessment, and Functional Independence Measure-cognitive showed good predictive validity. The Mini-Mental State Examination is the most widely used cognitive screening instrument, but shows insufficient criterion validity. None of the existing instruments fulfils all criteria. The Montreal Cognitive Assessment is the best candidate at present, provided items measuring speed of information processing are added, and further studies investigating the optimal cut-offs are conducted. © The Author(s) 2014.

    To investigate the validity of previously suggested dimensions underlying the Mini-Mental State Examination (MMSE) and differences in associations of these dimensions with sociodemographic and health characteristics in an older Latin-American community sample with low levels of education. Secondary analysis of baseline data from a population-based cohort study. Bambuí, Brazil. Of 1,742 total residents aged 60 years or older, 1,558 (89.4%) participated at this study. A standard Brazilian version of the MMSE. A five-factor solution (Concentration, Language/Praxis, Orientation, Attention, and Memory) for the MMSE was generated from Principal Components Analysis, and the five-factor solutions proposed in previous studies of developed nation samples were tested in this sample by Confirmatory Factor Analysis. In the adjusted linear regression models, MMSE factors varied in their correlates: for example, female gender was associated with higher concentration, orientation, and attention but lower Language/Praxis; increased age was inversely associated only with language and attention; and activity of daily living impairment was principally associated with lower Language/Praxis. This study provides support for the cross-sectional equivalence of the MMSE, suggesting that most of the items and underlying constructs remain meaningful after alteration and translation in a low-education sample with lower overall distribution of scores.

    Previous work combining the Mini-Mental State Examination (MMSE) and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) has been conducted in western populations. We ascertained, in an Asian population, (1) the best method of combining the tests, (2) the effects of educational level, and (3) the effect of different dementia etiologies. Data from 576 patients were analyzed (407 nondemented controls, 87 Alzheimer's disease and 82 vascular dementia patients). Sensitivity, specificity and AUC values were obtained using three methods, the 'And' rule, the 'Or' rule, and the 'weighted sum' method. The 'weighted sum' rule had statistically superior AUC and specificity results, while the 'Or' rule had the best sensitivity results. The IQCODE outperformed the MMSE in all analyses. Patients with no education benefited more from combined tests. There was no difference between Alzheimer's disease and vascular dementia populations in the predictive value of any of the combined methods. We recommend that the IQCODE be used to supplement the MMSE whenever available and that the 'weighted sum' method be used to combine the MMSE and the IQCODE, particularly in populations with low education. As the study population selected may not be representative of the general population, further studies are required before generalization to nonclinical samples. (c) 2007 S. Karger AG, Basel.

    Missing values are commonly encountered on the Mini Mental State Examination (MMSE), particularly when administered to frail older people. This presents challenges for MMSE scoring in research settings. We sought to describe missingness in MMSEs administered in long-term-care facilities (LTCF) and to compare and contrast approaches to dealing with missing items. As part of the Care and Construction project in Nova Scotia, Canada, LTCF residents completed an MMSE. Different methods of dealing with missing values (e.g., use of raw scores, raw scores/number of items attempted, scale-level multiple imputation [MI], and blended approaches) are compared to item-level MI. The MMSE was administered to 320 residents living in 23 LTCF. The sample was predominately female (73%), and 38% of participants were aged >85 years. At least one item was missing from 122 (38.2%) of the MMSEs. Data were not Missing Completely at Random (MCAR), χ 2 (1110) = 1,351, p < 0.001. Using raw scores for those missing <6 items in combination with scale-level MI resulted in the regression coefficients and standard errors closest to item-level MI. Patterns of missing items often suggest systematic problems, such as trouble with manual dexterity, literacy, or visual impairment. While these observations may be relatively easy to take into account in clinical settings, non-random missingness presents challenges for research and must be considered in statistical analyses. We present suggestions for dealing with missing MMSE data based on the extent of missingness and the goal of analyses. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V.

    To identify minimal sets of Mini-Mental State Examination (MMSE) items that can distinguish normal control subjects from patients with mild Alzheimer's disease (AD), patients with mild from those with moderate AD, and those with moderate from those with severe AD. Two randomly selected equivalent half samples. Results of logistic regression analysis from data from the first half of the sample were confirmed by receiver operating characteristic curves on the second half. Memory disorders clinics at major medical centers in the United States affiliated with the Consortium to establish a Registry for Alzheimer's Disease (CERAD). White, normal control subjects (n = 412) and patients with AD (n = 621) who met CERAD criteria; nonwhite subjects (n = 165) and persons with missing data (n = 27) were excluded. Three four-item sets of MMSE items that discriminate, respectively, (1) normal controls from patients with mild AD, (2) patients with mild from those with moderate AD, and (3) patients with moderate from those with severe AD. The MMSE items discriminating normal controls from patients with mild AD were day, date, recall of apple, and recall of penny; those discriminating patients with mild from those with moderate AD were month, city, spelling world backward, and county, and those discriminating patients with moderate from those with severe AD were floor of building, repeating the word table, naming watch, and folding paper in half. Performance on the first two four-item sets was comparable with that of the full MMSE; the third set distinguished patients with moderate from those with severe AD better than chance. A minimum set of MMSE items can effectively discriminate normal controls from patients with mild AD and between successive levels of severity of AD. Data apply only to white patients with AD. Performance in minorities, more heterogeneous groups, or normal subjects with questionable cognitive status has not been assessed.

    Although the Mini-Mental State Examination (MMSE), Clinical Dementia Rating-Sum of Boxes (CDR-SOB), and neuropsychological batteries are widely used for evaluating cognitive function, it remains elusive which instrument best reflects the longitudinal disease progression in amnestic mild cognitive impairment (aMCI) and probable Alzheimer disease (AD). We investigated whether changes in these three instruments over time correlate with loss of cortical gray matter volume (cGMV). We retrospectively investigated 204 patients (aMCI, n = 114; AD, n = 90) who had undergone MMSE, CDR-SOB, the dementia version of the Seoul Neuropsychological Screening Battery (SNSB-D), and 3-dimensional T1-weighted magnetic resonance images at least twice. We investigated the partial correlation between annual decline in test scores and percent change of cGMV. In aMCI patients, changes in the SNSB-D total score (r = 0.340, p < 0.001) and CDR-SOB (r = 0.222, p = 0.020), but not MMSE, showed a correlation with cGMV loss, with the SNSB-D total score showing the strongest correlation. In AD patients, decline in all three test scores correlated significantly with cGMV loss, with MMSE exhibiting the strongest correlation (r = 0.464, p < 0.001). In aMCI patients, neuropsychological battery, though time-consuming, was the most adequate tool in tracking disease progression. In AD patients, however, MMSE may be the most effective longitudinal monitoring tool when considering cost-effectiveness. © 2017 S. Karger AG, Basel.

    To evaluate how much the Addenbrooke's Cognitive Examination-revised (ACE-R) improves the estimate of cognitive ability from the Mini-Mental State Examination (MMSE) in people with Alzheimer disease (AD). We examined itemized data in people with AD who were on the Scottish Dementia Research Interest Register drawn from eight centres across Scotland, covering 75% of the Scottish population. ACE-R items that comprise the MMSE and those that did not (non-MMSE items) were summed separately. We residualized MMSE total on non-MMSE total and vice versa to derive a measure of the variance unique to each. Five hundred and one (258 male, 243 female) participants, mean age 75.7 (range 52-94) years were on the register, of whom 329 (160 men, 169 women) had AD. Of those with AD, 309 had a mean MMSE of 20.5 and mean ACE-R of 57.5 measured with Pearson r = 0.92 between MMSE and ACE-R totals, and the regression equation ACE-R score = 3.0 × MMSE - 4.1. The unique non-MMSE items score correlated with ACE-R total r = 0.40 (16% of ACE-R variance). The ACE-R and MMSE total scores are highly correlated. In this clinical sample of people with established AD, for an MMSE score of 24, the predicted ACE-R score was 67.9 with 95% confidence intervals of 61.6-75.4. The extra non-MMSE ACE-R items improve estimates of cognitive ability by 16%. Copyright © 2012 John Wiley & Sons, Ltd.

    The Mini-Mental State Examination (MMSE) is one of the most frequently used cognitive measures for dementia severity and linked to deficits in everyday functioning. Recently, the Montreal Cognitive Assessment (MoCA) and the Addenbrooke's Cognitive Examination III (ACE-III) increasingly substitute for the MMSE. However, there are no specific cutoffs in the ACE-III for mild dementia. The objectives of this exploratory study were to assess the sensitivity of each scale to everyday functioning and to examine the cutoffs between mild and moderate dementia on the ACE-III. People with mild dementia completed the MMSE, MoCA and ACE-III, whilst informal carers completed the Revised Interview for Deteriorations in Daily Living Activities for Dementia to rate their relative's initiative and performance of instrumental activities of daily living and the Katz activities of daily living scale. Data were analysed using correlation analysis, raw score comparisons, Cohen's kappa and receiver operating characteristics analysis. Thirty-three dyads completed the measures. The ACE-III was the most sensitive tool for everyday functioning performance, whilst its language subscale was specifically related to initiation of activities. The most suitable cutoff on the ACE-III between mild and moderate dementia was 61. Findings suggest the ACE-III more efficiently identifies everyday functional impairments. Further research is required to confirm these exploratory analyses of the cutoff between mild and moderate dementia on the ACE-III. Both functional impairment and stage of dementia are needed in the diagnostic process and in the clinical assessment of people with dementia. Copyright © 2016 John Wiley & Sons, Ltd.

    Background Dementia is considered widely under-detected in primary care, and general practitioners (GPs) frequently ask for easy to use tools to assist in its early detection.Aim To determine the degree of correlation between the Mini-Cog Assessment (Mini-Cog) as performed by GPs and the Mini-Mental State Examination (MMSE).Design of study This was a prospective study (2005, 2006) comparing two cognitive screening instruments.Setting Ten general practices in Austria, with patients with a hitherto undiagnosed suspicion of dementia seen consecutively.Method Sensitivity, specificity and positive and negative predictive values (PPVs and NPVs) of the Mini-Cog (applying both a colour-coded and the original rating method) were assessed for degree of correlation with the MMSE. In phase one GPs examined patients suspected of having dementia using the Mini-Cog; in phase two a neurologist retested them applying the MMSE, a clock-drawing test (CDT) and a routine clinical examination. A questionnaire on the practicability of the Mini-Cog was answered by GPs.Results Of the 107 patients who participated 86 completed the whole study protocol. The Mini-Cog, as performed by the ten GPs, displayed a sensitivity of 0.85 (95% CI: 0.71, 0.98), a specificity of 0.58 (95% CI: 0.46, 0.71), a PPV of 0.47 (95% CI: 0.33, 0.61) and an NPV of 0.90 (95% CI: 0.80, 0.99) as against the MMSE carried out by neurologists. The GPs judged the Mini-Cog useful and time saving.Conclusion The Mini-Cog has a high sensitivity and acceptable specificity in the general practice setting and has proved to be a practicable tool for the diagnosis of dementia in primary care.

    The purpose of this study was to compare a modified version of the Mini-Mental State Examination (MMSE) with the standard MMSE and the Mini-Cog in patients ≥65 years old, stratified by education and literacy level. This cross-sectional exploratory study enrolled a convenience sample of 219 patients with a complaint of memory loss or a diagnosis of dementia from a geriatric outpatient clinic, nursing home, senior center, and university hospital. The MMSE was administered, and in addition to spelling and serial 7s backward, patients were asked to recite the days of the week backward with the intent to reduce educational bias. Scores on the modified MMSE were compared with scores of the MMSE and the Mini-Cog. Of the 219 patients, 157 were identified with cognitive impairment by the Mini-Cog. Using a cutoff of ≤23, the MMSE identified 118 patients and the modified MMSE identified 91 patients with cognitive impairment, and with a cutoff of ≤27 the MMSE identified 168 and the modified MMSE 149 patients. All cognitively intact subjects correctly recited the days of the week backward. Specificity of the modified MMSE was higher than the MMSE for most groups. The highest sensitivity and specificity (94% and 88%, respectively) as well as positive and negative predictive values (96% and 81%, respectively) were in patients with low levels of education for the modified MMSE using a cut off of ≤27. Using the days of the week in the MMSE among illiterate and semiliterate participants and with education less than high school, and using a cutoff of 27 of 30, correlates better with Mini-Cog for dementia screening, with fewer false positives.

    Purpose: To determine the incidence of brain atrophy and dementia after whole-brain radiotherapy (WBRT) in patients with brain metastases not undergoing surgery. Methods and Materials: Eligible patients underwent WBRT to 40 Gy in 20 fractions with or without a 10-Gy boost. Brain magnetic resonance imaging or computed tomography and Mini-Mental State Examination (MMSE) were performed before and soon after radiotherapy, every 3 months for 18 months, and every 6 months thereafter. Brain atrophy was evaluated by change in cerebrospinal fluid-cranial ratio (CCR), and the atrophy index was defined as postradiation CCR divided by preradiation CCR. Results: Of 101 patients (median age, 62 years) entering the study, 92 completed WBRT, and 45, 25, and 10 patients were assessable at 6, 12, and 18 months, respectively. Mean atrophy index was 1.24 ± 0.39 (SD) at 6 months and 1.32 ± 0.40 at 12 months, and 18% and 28% of the patients had an increase in the atrophy index by 30% or greater, respectively. No apparent decrease in mean MMSE score was observed after WBRT. Individually, MMSE scores decreased by four or more points in 11% at 6 months, 12% at 12 months, and 0% at 18 months. However, about half the decrease in MMSE scores was associated with a decrease in performance status caused by systemic disease progression. Conclusions: Brain atrophy developed in up to 30% of patients, but it was not necessarily accompanied by MMSE score decrease. Dementia after WBRT unaccompanied by tumor recurrence was infrequent

    OBJECTIVES To examine Montreal Cognitive Assessment (MoCA) performance in patients with Parkinson’s disease (PD) with “normal” global cognition according to Mini-Mental State Examination (MMSE) score. DESIGN A cross-sectional comparison of the MoCA and the MMSE. SETTING Two movement disorders centers at the University of Pennsylvania and the Philadelphia Veterans Affairs Medical Center. PARTICIPANTS A convenience sample of 131 patients with idiopathic PD who were screened for cognitive and psychiatric complications. MEASUREMENTS Subjects were administered the MoCA and MMSE, and only subjects defined as having a normal age- and education-adjusted MMSE score were included in the analyses (N = 100). As previously recommended in patients without PD, a MoCA score less than 26 was used to indicate the presence of at least mild cognitive impairment (MCI). RESULTS Mean MMSE and MoCA scores ± standard deviation were 28.8 ± 1.1 and 24.9 ± 3.1, respectively. More than half (52.0%) of subjects with normal MMSE scores had cognitive impairment according to their MoCA score. Impairments were seen in numerous cognitive domains, including memory, visuospatial and executive abilities, attention, and language. Predictors of cognitive impairment on the MoCA using univariate analyses were male sex, older age, lower educational level, and greater disease severity; older age was the only predictor in a multivariate model. CONCLUSION Approximately half of patients with PD with a normal MMSE score have cognitive impairment based on the recommended MoCA cutoff score. These results suggest that MCI is common in PD and that the MoCA is a more sensitive instrument than the MMSE for its detection. PMID:19170786

    Purpose While Cognitive impairment (CI) has been identified as an independent risk factors for mortality in patients undergoing peritoneal dialysis (PD), it is inadequately assessed. We evaluated the applicability of the Modified Mini-Mental State Examination (3MS) in assessing specific cognitive function and compared it to a detailed neuropsychological test battery as the reference standard. Methods In this multicentric cross-sectional study, we enrolled 445 clinically stable patients from five PD units, who were undergoing PD for at least 3 months. The 3MS was evaluated for general cognitive function. A detailed neuropsychological battery including domains of immediate memory, delayed memory, executive function, language, and visuospatial ability were evaluated as reference standards. Sensitivity and specificity of the 3MS was determined by using receiver operating characteristic (ROC) analysis. Results The CI prevalence evaluated by 3MS was 23.6%. PD patients with CI performed worse in all cognitive domains. The 3MS correlated well with specific cognitive domains. However, 18.5%, 57.4%, 12.6%, 8.8%, and 41.2% of patients whom were idendified as normal by 3MS still showed executive dysfunction, immediate memory impairment, delayed memory impairment, and language-ability and visuospatial-ability impairment, respectively. The 3MS identified patients having specific cognitive dysfunction with varied extent of diagnostic value, with 0.50, 0.42, 0.35, 0.34, and 0.26 of Youden index in executive function, delayed memory, language ability, immediate memory, and visuospatial ability, respectively. Conclusions The 3MS is not a comprehensive instrument for major cognitive domains in PD patients. It could, however, be used for executive dysfunction and delayed memory impairment screening.

    The aim of this study was to compare the screening value of the Mini-Cog, Clock Drawing Test (CDT), Mini-Mental State Examination (MMSE) and the algorithm MMSE and/or CDT to separate elderly people with dementia from healthy depending on test time, type and severity of dementia, and demographic variables in a German Memory Clinic. Data from a heterogeneous patient sample and healthy participants (n = 502) were retrospectively analyzed. Of the 438 patients with dementia, 49.1% of the dementia diagnoses were Alzheimer's dementia and 50.9% were non-Alzheimer's dementia. Sixty-four participants were classified as cognitively unimpaired. The CDT and an extraction of the 3-item recall of the MMSE were used to constitute the Mini-Cog algorithm. Overall, the Mini-Cog showed significantly higher discriminatory power (86.8%) than the MMSE (72.6% at a cut-off ≤ 24 and 79.2% at ≤ 25, respectively) and CDT (78.1%) (each p 0.05). The specificity of the Mini-Cog (100.0%) was similar to that of the MMSE (100.0% for both cut-offs) and CDT (96.9%) (p = 0.154). For all age and educational groups the Mini-Cog outmatched the CDT and MMSE, and was less affected by education than MMSE and less susceptible for the dementia stage than the CDT. The Mini-Cog proved to have superior discriminatory power than either CDT or MMSE and is demonstrated to be a valid "short" screening instrument taking 3 to 4 minutes to administer in the geriatric setting.

    The Cognitive Performance Scale (CPS) is generated from five items of the interRAI/ Minimum Data Set instruments, a comprehensive geriatric assessment method. CPS was initially designed to assess cognition in residential care, where it has shown good psychometric performance. We evaluated the performance of the interRAI Acute Care in identifying cognitive impairment among patients hospitalized on acute geriatric wards. An observational study was conducted on two geriatric wards. Trained raters independently completed the interRAI Acute Care and the Mini-Mental State Examination (MMSE) in 97 inpatients (85 ± 5 years; 67% female). The level of agreement between CPS and MMSE was explored using comparisons of means, agreement coefficients, and diagnostic accuracy. Cognitive impairment was present in 61% of the participants. Average MMSE scores were significantly different between groups with low CPS scores compared with those with high CPS scores (p <0.05). CPS explained only 48.8% of the variability in MMSE. Agreement in defining cognitively impaired subjects was moderate (percentage observed agreement, 68%; κ = 0.41). With MMSE score less than 24 as a gold standard, diagnostic accuracy of CPS was moderate (area under curve = 0.73), with low sensitivity, but excellent specificity. When lowering the MMSE cutoff to less than 18 and focusing on patients with severe cognitive impairment, CPS agreement coefficients and sensitivity increased but specificity decreased. Using education-adjusted MMSE cutoffs did not substantially affect the results. CPS can be used for coarse triage between intact and severe cognitive impairment. Although promising results have been obtained in residential and community settings, our results suggest that CPS fails to differentiate across different levels of cognitive impairment in hospitalized geriatric patients.

    The validity and reliability of the Abbey Pain Scale-Japanese version (APS-J) have been examined. However, the range of cognitive levels for which the APS-J can be accurately used in older adults has not been investigated. This study aimed to examine the differences between total/item scores of the APS-J and Mini-Mental State Examination (MMSE) scores of residents in aged care facilities who self-reported the presence or absence of pain. This descriptive study included 252 residents in aged care facilities. Self-reported pain, MMSE scores, and item/total APS-J scores for pain intensity were collected. The MMSE scores were used to create four groups on the basis of the cognitive impairment level. Self-reports of pain and the APS-J scores were compared with different MMSE score groups. The total APS-J score for pain intensity as well as scores for individual items such as "vocalization" and "facial expression" were significantly higher in those who reported pain than in those reporting no pain across all MMSE groups. The total APS-J score and item scores for "vocalization," "change in body language," and "behavioral changes" showed significant differences in the four MMSE groups. Pain intensity tended to be overestimated by the APS-J, especially among those with low MMSE scores. The APS-J can be used to assess pain intensity in residents despite their cognitive levels. However, caution is required when using it to compare scores among older adults with different cognitive capacity because of the possibility of overestimation of pain among residents with low cognitive capacity.

    To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain-MCI (sd-MCI) and multiple domain-MCI (md-MCI). Area under the receiver operating characteristic curve (ROC) analysis was used to compare the discriminatory ability of the MoCA and the MMSE. Two hundred thirty patients were recruited, of which 136 (59.1%) were diagnosed with dementia, 61 (26.5%) with MCI, and 33 (14.3%) with no cognitive impairment (NCI). The majority of MCI patients had md-MCI (n = 36, 59%). The MoCA had significantly larger AUCs than the MMSE in discriminating md-MCI from the lower risk group for incident dementia (NCI and sd-MCI) [MoCA 0.92 (95% CI, 0.86-0.98) vs. MMSE 0.84 (95% CI, 0.75-0.92), p = 0.02). At their optimal cut-off points, the MoCA (19/20) remained superior to the MMSE (23/24) in detecting md-MCI [sensitivity: 0.83 vs. 0.72; specificity: 0.86 vs. 0.83; PPV: 0.79 vs. 0.72; NPV: 0.89 vs. 0.83; correctly classified: 85.1% vs. 78.7%]. The MoCA is superior to the MMSE in the detection of patients with cognitive impairment at higher risk for incident dementia at a memory clinic setting.

    BACKGROUND/STUDY CONTEXT: Although many of the Mini-Mental State Examination's (MMSE) limitations are well accepted among geriatricians, neuropsychologists, and other interested clinicians and researchers, its continued use in psychometrically unsound ways suggests that additional investigation and dissemination of information are sorely needed. The authors aimed to describe the reliability and validity of the MMSE as a measure of cognitive function among healthy older adults. The authors examined MMSE performance in 124 stroke- and dementia-free, community-dwelling older adults (65% male; mean age = 66.5 years). All participants were administered an extensive neuropsychological battery composed of measures of attention, executive function, memory, and visuospatial function. A subset of 99 participants also underwent magnetic resonance imaging (MRI). MMSE test-retest reliability was examined among 65 participants who underwent repeat MMSE testing over an average interval of 83.2 days. Spearman test-retest correlation for total MMSE scores was r S = .35 (p = .004), for Serial Sevens was r S = .40 (p = .001), and for Word Recall was r S = -.01 (p = .96). Total MMSE performance correlated significantly with a minority of neuropsychological tests and MRI-derived indices of white matter disease and brain atrophy. A subset of 17% of participants demonstrated inappropriate intrusion of MMSE Pentagon Copy during another test of visuospatial recall. Overall, MMSE scores exhibited ceiling effects, poor test-retest reliability, limited sensitivity to subtle brain abnormalities, and a high rate of intrusion elsewhere in the neuropsychological battery. Individual MMSE items demonstrated poor construct validity. These qualities illustrate the serious limitations of the MMSE in detecting individual differences in cognitive function among healthy older adults.

    To assess the validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in the detection of vascular mild cognitive impairment (VaMCI) in patients with subcortical ischemic vascular disease (SIVD). Among 102 SIVD patients, both cutoff scores of the MMSE and MoCA for differentiating VaMCI from no cognitive impairment (NCI) or differentiating VaMCI from vascular dementia (VaD) were determined by the receiver operator characteristic (ROC) analysis. Optimal sensitivity with specificity of cutoff scores was obtained after the raw scores were adjusted for education. After adjusting for education, the MoCA cutoff score for differentiating VaMCI from NCI was at 24/25 and that for differentiating VaMCI from VaD was at 18/19. After applying the adjusted MoCA scores from 19 to 24 to identify VaMCI in all SIVD patients, sensitivity was at 76.7% and specificity was at 81.4% (κ = 0.579). The adjusted cutoff score of the MMSE for differentiating VaMCI from NCI was at 28/29 and that for differentiating VaMCI from VaD was at 25/26. The sensitivity and specificity of the adjusted MMSE was at 58.1 and 71.2%, respectively, when using the score from 26 to 28 to identify VaMCI in SIVD patients (κ = 0.294). The MoCA detected subcortical VaMCI better than the MMSE. © 2013 S. Karger AG, Basel.

    The Oxford Cognitive Screen (OCS) was recently developed with the aim of describing the cognitive deficits after stroke. The scale consists of 10 tasks encompassing five cognitive domains: attention and executive function, language, memory, number processing, and praxis. OCS was devised to be inclusive and un-confounded by aphasia and neglect. As such, it may have a greater potential to be informative on stroke cognitive deficits of widely used instruments, such as the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment, which were originally devised for demented patients. The present study compared the OCS with the MMSE with regards to their ability to detect cognitive impairments post-stroke. We further aimed to examine performance on the OCS as a function of subtypes of cerebral infarction and clinical severity. 325 first stroke patients were consecutively enrolled in the study over a 9-month period. The OCS and MMSE, as well as the Bamford classification and NIHSS, were given according to standard procedures. About a third of patients (35.3%) had a performance lower than the cutoff (cognitive domains of the OCS. Using the MMSE as a standard of clinical practice, the comparative sensitivity of OCS was 100%. Out of the 208 patients with normal MMSE performance 180 showed impaired performance in at least one domain of the OCS. The discrepancy between OCS and MMSE was particularly strong for patients with milder strokes. As for subtypes of cerebral infarction, fewer patients demonstrated widespread impairments in the OCS in the Posterior Circulation Infarcts category than in the other categories. Overall, the results showed a much higher incidence of cognitive impairment with the OCS than with the MMSE and demonstrated no false negatives for OCS vs MMSE. It is concluded that OCS is a sensitive screen tool for cognitive deficits after stroke. In particular, the OCS detects high incidences of stroke-specific cognitive impairments, not detected

    Cognitive impairment in end-stage renal disease patients is associated with an increased risk of mortality. We examined the cognitive function in hemodialysis (HD) patients and compared the Korean versions of the Montreal Cognitive Assessment (K-MoCA) and of the Mini-Mental State Examination (K-MMSE) to identify the better cognitive screening instrument in these patients. Thirty patients undergoing hemodialysis and 30 matched reference group of apparently healthy control were included. All subjects underwent the K-MoCA, K-MMSE and a neuropsychological test battery to measure attention, visuospatial function, language, memory and executive function. All cognitive data were converted to z-scores with appropriate age and education level prior to group comparisons. Cognitive performance 1.0 SD below the mean was defined as modest cognitve impairment while 1.5 below the mean was defined as severe cognitive impairment. Modest cognitive impairment in memory plus other cognitive domains was detected in 27 patients (90%) while severe cognitive impairment in memory plus other cognitive domains was detected in 23 (77%) patients. Total scores in the K-MoCA were significantly lower in HD patients than in the reference group. However, no significant group difference was found in the K-MMSE. The K-MMSE ROC AUC (95% confidence interval) was 0.72 (0.59-0.85) and K-MoCA ROC AUC was 0.77 (0.65-0.89). Cognitive impairment is common but under-diagnosed in this population. The K-MoCA seems to be more sensitive than the K-MMSE in HD patients.

    Full Text Available BackgroundThe Oxford Cognitive Screen (OCS was recently developed with the aim of describing the cognitive deficits after stroke. The scale consists of 10 tasks encompassing five cognitive domains: attention and executive function, language, memory, number processing, and praxis. OCS was devised to be inclusive and un-confounded by aphasia and neglect. As such, it may have a greater potential to be informative on stroke cognitive deficits of widely used instruments, such as the Mini-Mental State Examination (MMSE or the Montreal Cognitive Assessment, which were originally devised for demented patients.ObjectiveThe present study compared the OCS with the MMSE with regards to their ability to detect cognitive impairments post-stroke. We further aimed to examine performance on the OCS as a function of subtypes of cerebral infarction and clinical severity.Methods325 first stroke patients were consecutively enrolled in the study over a 9-month period. The OCS and MMSE, as well as the Bamford classification and NIHSS, were given according to standard procedures.ResultsAbout a third of patients (35.3% had a performance lower than the cutoff (<22 on the MMSE, whereas 91.6% were impaired in at least one OCS domain, indicating higher incidences of impairment for the OCS. More than 80% of patients showed an impairment in two or more cognitive domains of the OCS. Using the MMSE as a standard of clinical practice, the comparative sensitivity of OCS was 100%. Out of the 208 patients with normal MMSE performance 180 showed impaired performance in at least one domain of the OCS. The discrepancy between OCS and MMSE was particularly strong for patients with milder strokes. As for subtypes of cerebral infarction, fewer patients demonstrated widespread impairments in the OCS in the Posterior Circulation Infarcts category than in the other categories.ConclusionOverall, the results showed a much higher incidence of cognitive impairment with the OCS than with the

    In older patients, evaluation of the cognitive status is crucial. The Mini-Mental State Examination (MMSE) is widely used for screening of cognition, providing fairly high sensitivity, specificity and reproducibility. Recently, a consensus emerged on the necessity of an international and transparent language, as provided by the WHO's International Classification of Functioning, Disability and Health (ICF). Most assessment tools however are not in accordance with the ICF. To reformulate the MMSE according to the ICF, both for the individual items and for the scoring system. MMSE data (scores varying from 3 to 30/30) of (1) 217 cognitively healthy elderly, (2) 60 persons with mild cognitive impairment, (3) 60 patients with mild Alzheimer's disease (AD), and (4) 60 patients with moderate/severe AD were obtained from studies at a university hospital setting. Subjects were aged 65 years or more and recruited either through advertisement (group 1), from the geriatric day hospital (groups 2 and 3), or the geriatric ward (group 4). The allocation to the groups was done after multidisciplinary evaluation. The conversion of the MMSE to ICF-MMSE was done by content comparison and by subsequent translation of the scoring system using automatic algorithms. All MMSE items were converted to the corresponding ICF categories. Three ICF domains were addressed: global and specific mental functions, general tasks and demands, divided over 6 ICF categories (orientation time/place, sustaining attention, memory functions, mental functions of language, undertaking a simple task). Scores on individual items were transformed according to their relative weight on the original MMSE scale, and a total ICF-MMSE score from 0 (no problem) to 100 (complete problem) was generated. Translation was satisfying, as illustrated by a good correlation between MMSE and ICF-MMSE. The diagnostic groups were distributed over the ICF-MMSE scores as expected. For each ICF domain, ICF-MMSE subscores were higher

    The Montreal Cognitive Assessment (MoCA) has been shown to be more sensitive in detecting executive dysfunction than the Mini-Mental State Examination (MMSE). However, it is still not known whether all the MoCA executive subtests contribute to the superior sensitivity. Thus, the present study aimed to determine how much executive abnormality was detected by the MMSE and MoCA executive subtests in a population-based cohort of Chinese post-stroke patients. The MMSE and MoCA were collected from post-stroke patients (within 15 days to 1 month after stroke, including ischemic stroke and hemorrhagic stroke) in 14 hospitals of northern and southern China (including 10 top-graded hospitals and 4 community hospitals) between June 2011 and September 2013. The proportions of patients with incorrect MoCA executive subtests and the proportions of patients with incorrect MMSE executive subtests were compared. A total of 1222 patients (703 men and 519 women, aged 62.06 ± 10.68 and 62.76 ± 9.86 years, respectively) were recruited. The MoCA detected more patients with executive dysfunction than the MMSE (OR 15.399, 95% CI 12.631-18.773; P < 0.001). The likelihood of incorrect MMSE executive tasks increased across decreasing scores of MoCA executive tasks (P < 0.001 for trend). Compared with the MMSE three-step command test (15.5%), the MoCA trail-making (57.8%), abstraction (48.0%) and abstraction (measurement tool; 45.7%) detected more patients with executive dysfunction (P < 0.001), whereas the MoCA digit span forwards (4.3%) and backwards (11.6%) detected fewer patients (P < 0.001 and P = 0.005, respectively). The MoCA executive tasks are more sensitive in detecting executive dysfunction compared with the MMSE executive tasks. Geriatr Gerontol Int 2017; 17: 2329-2335. © 2017 Japan Geriatrics Society.

    To determine if Montreal Cognitive Assessment (MoCA) is more sensitive than the commonly used Mini-Mental State Examination (MMSE) in detecting cognitive abnormalities in patients with probable progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) compared with Parkinson's disease (PD). In this multicenter observational study, MMSE and MoCA were administered in a random order to 130 patients: 35 MSA, 30 PSP and 65 age, and education and gender matched-PD. We assessed between-group differences for MMSE, MoCA, and their subitems. Receiver-operating characteristic (ROC) curves were calculated. The mean MMSE was higher than the mean MoCA score in each MSA (27.7 ± 2.4 vs. 22.9 ± 3.0, p < 0.0001), PSP (26.0 ± 2.9 vs. 18.2 ± 3.9, p < 0.0001), and PD (27.3 ± 2.0 vs. 22.3 ± 3.5, p < 0.0001). MoCA total score as well as its letter fluency subitem differentiated PSP from MSA and PD with high specificity and moderate sensitivity. More specifically, a cut-off score of 7 F-words or less per minute would support a diagnosis of PSP (PSP vs. PD: 86 % specificity, 70 % sensitivity; PSP vs. MSA: 71 % specificity, 70 % sensitivity). By contrast, MMSE presented an overall ceiling effect for most subitems, except for the pentagon scores, where PSP did less well than MSA or PD patients. These preliminary results suggest that PSP and MSA, similar to PD patients, may present normal MMSE and reduced MoCA performance. Overall, MoCA is more sensitive than MMSE in detecting cognitive impairment in atypical parkinsonism and together with verbal fluency would be a useful test to support PSP diagnosis.

    We investigated the factors associated with the reliability of insulin self-injection in elderly diabetic patients receiving insulin therapy. We enrolled diabetic patients aged ≥65 years and receiving insulin therapy, and assessed their cognitive function by the mini-mental state examination and 1-min mental status examination for category fluency. We also observed their technique of insulin self-injection, and evaluated whether or not patients were able to inject insulin by themselves according to nine defined details in terms of insulin self-injection. The predictive factors for the reliability of insulin self-injection were determined by univariate and multivariate logistic regression analysis. There were 278 participants (135 males, 143 females) enrolled in the present study. According to multivariate logistic regression analysis, only the 1-min mental status examination score was found to be a significant independent predictor of the reliability of insulin self-injection (odds ratio 0.75; 95% confidence interval 0.62-0.90; P = 0.002). The 1-min mental status examination for category fluency can be considered more useful than mini-mental state examination to evaluate the reliability of insulin self-injection in elderly diabetic patients receiving insulin therapy.

    The objectives of this study were to examine the reliability and validity of a 26-point telephone version of the Cantonese Mini-mental State Examination (T-CMMSE) for a sample of 65 elderly patients, comprising 31 patients without dementia and 34 patients with dementia, in an acute regional hospital in Hong Kong, and to identify an optimal cut-off score to discriminate between those patients with dementia and those without. Participants were rated by using the face-to-face Mini-mental State Examination (MMSE) before inpatient discharge and the T-CMMSE after inpatient discharge, and were rated separately by two raters in two telephone follow-up sessions using the T-CMMSE. The results of the study indicated that the scale had excellent inter-and intra-rater reliabilities. There was substantial agreement between the two versions of the examination (kappa > 0.6-0.8 < or =) for orientation, registration, and recall items. An optimal cut-off score of < or = 16 was suggested for the T-CMMSE to discriminate between those with and without dementia. The T-CMMSE can be used in telephone follow-ups as an alternative to the conventional face-to-face version.

    The Mini Mental State Examination (MMSE) is a cognitive test that is commonly used as part of the evaluation for possible dementia. To determine the diagnostic accuracy of the Mini-Mental State Examination (MMSE) at various cut points for dementia in people aged 65 years and over in community and primary care settings who had not undergone prior testing for dementia. We searched the specialised register of the Cochrane Dementia and Cognitive Improvement Group, MEDLINE (OvidSP), EMBASE (OvidSP), PsycINFO (OvidSP), LILACS (BIREME), ALOIS, BIOSIS previews (Thomson Reuters Web of Science), and Web of Science Core Collection, including the Science Citation Index and the Conference Proceedings Citation Index (Thomson Reuters Web of Science). We also searched specialised sources of diagnostic test accuracy studies and reviews: MEDION (Universities of Maastricht and Leuven, www.mediondatabase.nl), DARE (Database of Abstracts of Reviews of Effects, via the Cochrane Library), HTA Database (Health Technology Assessment Database, via the Cochrane Library), and ARIF (University of Birmingham, UK, www.arif.bham.ac.uk). We attempted to locate possibly relevant but unpublished data by contacting researchers in this field. We first performed the searches in November 2012 and then fully updated them in May 2014. We did not apply any language or date restrictions to the electronic searches, and we did not use any methodological filters as a method to restrict the search overall. We included studies that compared the 11-item (maximum score 30) MMSE test (at any cut point) in people who had not undergone prior testing versus a commonly accepted clinical reference standard for all-cause dementia and subtypes (Alzheimer disease dementia, Lewy body dementia, vascular dementia, frontotemporal dementia). Clinical diagnosis included all-cause (unspecified) dementia, as defined by any version of the Diagnostic and Statistical Manual of Mental Disorders (DSM); International Classification of

    BACKGROUND: Mini-mental state examination (MMSE) of Chinese version has been widely used to survey cognitive function of elder people; especially, it shows a good reliability and validity for elder people in city.However, whether it is beneficial to measure cognitive function of elder people in countries in Guangxi Zhuang Autonomous Region should be further studied.OBJECTIVE: To investigate the feasibility, reliability and validity of the cognitive function among the elderly people aged over 65 years from Jiazhuan in Bama County of Guangxi Zhuang Autonomous Region by using the MMSE of Chinese version.DESIGN: Prevalence survey.SETTING: Department of Psychology, Nanjing Municipal Social Welfare Hospital; Department of Psychology,Yizhou Municipal Jiulong Railroad Hospital; Long Life's Institute of Bama County.PARTICIPANTS: A total of 320 old persons over 65 years old were sampled on the basis of the unit of village of Jiazhuan in Bama County of Guangxi Zhuang Autonomous Region from the 12th to 28th, March 2004. All the subjects provided the confirmed consents.METHODS: ① Mental Health Questionnaire of long life's old man was adopted including demographic data and international standardized MMSE in Chinese. The survey of MMSE was divided into two phases: In the first phase, every case was examined by MMSE. The positive result was decided by the education level. Illiterate group, who was educated less than one year, then his MMSE scores must be less than 17; primary school group, who was educated from 1 to 6 years, then his MMSE must be less than 20; middle school group, who was educated more than 7 years, then his MMSE must be less than 24. In the second phase, these cases with positive MMSE score were given the neuro-psycho and mental health examination to confirm the dementia types after diagnosis. The content of the questionnaire was revised properly without changing the meaning of the questionnaire. The interclass correlation coefficient of MMSE was 0.89.

    Screening tests play a crucial role in dementia diagnostics, thus they should be very sensitive for mild cognitive impairment (MCI) assessment. Nowadays, the MiniMental State Examination (MMSE) is the most commonly used scale in cognitive function evaluation, albeit it is claimed to be imprecise for MCI detection. The Montreal Cognitive Assessment (MoCA), was created as an alternative method for MMSE. Aim. MoCA vs. MMSE credibility assessment in detecting MCI, while taking into consideration the sensitivity and specificity by cut-off points. A systematic literature search was carried out by the authors using EBSCO host Web, Wiley Online Library, Springer Link, Science Direct and Medline databases. The following medical subject headings were used in the search: mild cognitive impairment, mini-mental state examination, Montreal cognitive assessment, diagnostics value. Papers which met inclusion and exclusion criteria were chosen to be included in this review. At the end, for the evaluation of MoCA 20, and MMSE 13 studies were qualified. Research credibility was established by computing weighted arithmetic mean, where weight is defined as population for which the result of sensitivity and specificity for the cut-off point was achieved. The cut-offs are shown as ROC curve and accuracy of diagnosis for MoCA and MMSE was calculated as the area under the curve (AUC). ROC curve analysis for MoCA demonstrated that MCI best detection can be achieved with a cut-off point of 24/25 (n = 9350, the sensitivity of 80.48% and specificity of 81.19%). AUC was 0.846 (95% CI 0.823-0.868). For MMSE, it turned out that more important cut-off was of 27/28 (n = 882, 66.34% sensitivity and specificity of 72.94%). AUC was 0.736 (95% CI 0.718-0.767). MoCA test better meets the criteria for screening tests for the detection of MCI among patients over 60 years of age than MMSE.

    Numerous neuropsychological tests are implemented in the clinical setting. However, a readily available cognitive test is required to detect the risk of dementia in the community setting. A total of 4151 persons aged ≥65 years participated in the present prospective cohort study. We assessed cognitive performance using the Mini-Mental State Examination and the National Center for Geriatrics and Gerontology-Functional Assessment Tool. The National Center for Geriatrics and Gerontology-Functional Assessment Tool includes tests of story and word list memory, attention and executive function, processing speed, and visuospatial skill to screen for cognitive impairment. All measurements were transformed to Z-scores to compare among the cognitive tests. The incidence of dementia was determined using data collected by the Japanese Health Insurance System over 36 months. After an average of 43 months, 180 (4.3%) participants were diagnosed with dementia. Survival analyses showed that the probability of dementia was significantly associated with all cognitive tests, except for visuospatial skill. The processing speed test showed the highest hazard ratios for the incidence of dementia (Z-score: hazard ratio 0.61, 95% confidence interval 0.50-0.75, P Mini-Mental State Examination, play an important role in detecting the risk of dementia in the community setting. Further analysis is required to identify the risk of dementia in older people without global cognitive impairment. Geriatr Gerontol Int 2017; 17: 2383-2388. © 2017 Japan Geriatrics Society.

    As the rapid growth of the elderly population and the increased prevalence of Alezheimer's Disease and related disorders, there is an increasing need for effective cognitive screening. The Mini Mental State Examination (MMSE) is the most frequently used screening test of cognitive impairment because of its convenience. The Montreal Cognitive Assessment-Indonesian Version (MoCA-INA) has been validated and recently been used as a cognitive screening tool. The aim of this study was to compare the MMSE and MoCA-INA scores and to determine the correlation between the MMSE and MoCA-INA scores in elderly. This was a cross-sectional study including 83 elderly subjects from November 2016 until June 2017. We performed MMSE and MoCA-INA for assessment of cognitive function and the time between each test was at least 30 minutes. The study included 83 subjects which were consisted of 46 (55.4%) males and 37 (44.6%) females. The mean age was 69.19 ± 4.23 ranging from 65 to 79 years old. The average MMSE scores was 24.96 ± 3.38 (range 14 to 30). The average MoCA-INA scores was 21.06 ± 4.56 (range 5 to 30). The Pearson correlation coefficient between the scores was 0.71 (p<0.005). There were no significant differences of both scores based on history of hypertension, diabetes mellitus and previous stroke, but there was a significant difference in MMSE scores based on level of education. The MoCA-INA score showed a good correlation with the MMSE score. Both tests showed comparable results but MoCA-INA showed lower average with wider range of scores.

    Dementia is increasingly prevalent due to rapid aging of the population, but under-recognized among people with low education levels. This is partly due to a lack of appropriate and precise normative data, which underestimates cognitive aging in the use of screening tools for dementia. We aimed to improve the precision of screening for cognitive impairment, by characterizing the patterns of cognitive aging and derived normative data of the Mini-Mental State Examination (MMSE) for illiterate and low-educated populations. This community-based study included data from 2,280 individuals aged 40 years or older from two rural areas. Multiple linear modeling examined the effect of aging on cognition reflected by the MMSE, stratified by education level and gender. Threshold effect of age on cognition was performed using a smoothing function. The majority of participants (60.4%) were illiterate or had attended only primary school (24.6%). The effect of aging on cognition varied by gender and education. Primary-school educated females and males remained cognitively stable up to 62 and 71 years of age, respectively, with MMSE score declining 0.4 and 0.8 points/year in females and males thereafter. Illiterates females scored 2.3 points lower than illiterate males, and scores for both declined 0.2 points/year. According to these results, normative data stratified by age, education and gender was generated. This study suggests gender and educational differences exist in cognitive aging among adults with limited or no formal education. To improve screening precision for cognitive impairment with the use of MMSE in low-educated population, age, gender, and education level should be considered.

    We examined the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting multiple-domain mild cognitive impairment (md-MCI) in a Chinese sub-sample drawn from elderly population-based study. This study included Chinese participants from the Epidemiology of Dementia in Singapore (EDIS) study aged ≥ 60 years who underwent cognitive screening with the Abbreviated Mental Test and Progressive Forgetfulness Questionnaire. Screen-positive participants subsequently underwent MoCA, MMSE, and a comprehensive formal neuropsychological battery. MCI was defined by Petersen's criteria and further classified into single-domain MCI (sd-MCI) and md-MCI. Area under the receiver operating characteristic curve (AUC) with 95% confidence intervals (CIs) was computed for the MoCA and the MMSE in detecting md-MCI. A total of 300 participants were recruited: 128 (42.7%) were diagnosed with no cognitive impairment (NCI), 47 (15.7%) with sd-MCI, and 83 (28.0%) with md-MCI. Forty-one participants were excluded, 7 (2.3%) had dementia, and 34 (11.3%) had only objective cognitive impairment without subjective complaints. Although the MoCA had a significantly larger AUC than the MMSE (0.94 (95% CI = 0.91-0.97) vs. 0.91 (95% CI = 0.86-0.95), p= 0.04), at optimal cut-off points, the MoCA (19/20) was equivalent to the MMSE (25/26) in detecting md-MCI (sensitivity: 0.80 vs. 0.87, specificity: 0.92 vs. 0.80). Both screening tests had good discriminant validity and can be used in detecting md-MCI in a sub-sample of Chinese drawn from a population-based study.

    Knowing the reliability of cognitive tests, particularly those commonly used in clinical practice, is important in order to interpret the clinical significance of a change in performance or a low score on a single test. To report the intra-class correlation (ICC), standard error of measurement (SEM) and minimum detectable change (MDC) for the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Color Trails Test (CTT) among community dwelling older adults. 130 participants aged 55 and older without severe cognitive impairment underwent two cognitive assessments between two and four months apart. Half the group changed rater between assessments and half changed time of day. Mean (standard deviation) MMSE was 28.1 (2.1) at baseline and 28.4 (2.1) at repeat. Mean (SD) MoCA increased from 24.8 (3.6) to 25.2 (3.6). There was a rater effect on CTT, but not on the MMSE or MoCA. The SEM of the MMSE was 1.0, leading to an MDC (based on a 95% confidence interval) of 3 points. The SEM of the MoCA was 1.5, implying an MDC95 of 4 points. MoCA (ICC = 0.81) was more reliable than MMSE (ICC = 0.75), but all tests examined showed substantial within-patient variation. An individual's score would have to change by greater than or equal to 3 points on the MMSE and 4 points on the MoCA for the rater to be confident that the change was not due to measurement error. This has important implications for epidemiologists and clinicians in dementia screening and diagnosis.

    The effectiveness of dementia screening depends on the availability of suitable screening tools with good sensitivity and specificity to confidently distinguish normal age-related cognitive decline from dementia. The aim of this study was to evaluate the discriminant validity of 7 screening measures for dementia. A sample of 140 participants aged ≥60 years living in a residential facility for the aged were assessed clinically and assigned caseness for dementia using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revised diagnostic criteria. Sensitivity and specificity of a selection of the following screening measures were tested using receiver operating characteristic (ROC) analysis for individual and combined tests: the Mini-Mental State Examination (MMSE), Six-Item Screener (SIS), Subjective Memory Complaint, Subjective Memory Complaint Clinical (SMCC), Subjective Memory Rating Scale (SMRS), Deterioration Cognitive Observee (DECO) and the Clock Drawing Test (CDT). Using ROC analyses, the SMCC, MMSE and CDT were found to be 'moderately accurate' in screening for dementia with an area under the curve (AUC) >0.70. The AUCs for the SIS (0.526), SMRS (0.661) and DECO (0.687) classified these measures as being 'less accurate'. At recommended cutoff scores, the SMCC had a sensitivity of 90.9% and specificity of 45.7%; the MMSE had a sensitivity of 63.6% and a specificity of 76.0%, and the CDT had a sensitivity of 44.4% and a specificity of 88.9%. Combining the SMCC and MMSE did not improve their predictive power except for a modest increase when using the sequential rule. The SMCC is composed of valid screening questions that have high sensitivity, are simple to administer and ideal for administration at the community or primary health care level as a first level of 'rule-out' screening. The MMSE can be included at a second stage of screening at the general hospital level and the CDT in specialist clinical settings. Sequential use of the

    The JLGK0901 study showed the noninferiority of stereotactic radiosurgery (SRS) alone as initial treatment of 5 to 10 brain metastases (BMs) compared with 2 to 4 BMs in terms of overall survival and most secondary endpoints (Lancet Oncol 2014;15:387-95). However, observation periods were not long enough to allow confirmation of the long-term safety of SRS alone in patients with 5 to 10 BMs. This was a prospective observational study of Gamma Knife SRS-treated patients with 1 to 10 newly diagnosed BMs enrolled at 23 facilities between March 1, 2009, and February 15, 2012. The 1194 eligible patients were categorized into the following groups: group A, 1 tumor (n=455); group B, 2 to 4 tumors (n=531); and group C, 5 to 10 tumors (n=208). Cumulative rates of Mini-Mental State Examination (MMSE) score maintenance (MMSE score decrease <3 from baseline) determined with a competing risk analysis of groups A, B, and C were 93%, 91%, and 92%, respectively, at the 12th month after SRS; 91%, 89%, and 91%, respectively, at the 24th month; 89%, 88%, and 89%, respectively, at the 36th month; and 87%, 86%, and 89%, respectively, at the 48th month (hazard ratio [HR] of group A vs group B, 0.719; 95% confidence interval [CI], 0.437-1.172; P=.18; HR of group B vs group C, 1.280; 95% CI, 0.696-2.508; P=.43). During observations ranging from 0.3 to 67.5 months (median, 12.0 months; interquartile range, 5.8-26.5 months), as of December 2014, 145 patients (12.1%) had SRS-induced complications. Cumulative complication incidences by competing risk analysis for groups A, B, and C were 7%, 8%, and 6%, respectively, at the 12th month after SRS; 10%, 11%, and 11%, respectively, at the 24th month; 11%, 11%, and 12%, respectively, at the 36th month; and 12%, 12%, and 13%, respectively, at the 48th month (HR of group A vs group B, 0.850; 95% CI, 0.592-1.220; P=.38; HR of group B vs group C, 1.052; 95% CI, 0.666-1.662, P=.83).

    Cognitive deficits are frequent stroke sequelae. Data from population-based stroke cohorts on the impact of cognitive deficits on long-term outcome are scarce. The purpose of this study was to investigate the impact of low mini-mental status on health outcome up to 5 years after first-ever stroke. Data were collected from the Erlangen Stroke Project, a population-based stroke registry covering a source population of 103,000 inhabitants. The Mini-Mental State Examination (MMSE) was used to assess global cognitive function. Health outcome included limitations in instrumental activities of daily living (IADL, Frenchay Activities Index), low independence in activities of daily living (ADL, Barthel Index), depressive symptoms (Zung Self Rating Depression Scale), and institutionalization. Using multivariate logistic regression analysis, association of an education-adjusted MMSE score ≤ 24 with these health outcomes was investigated within distinct models at 12, 36, and 60 months after stroke as well as predictors at 3 months for low IADL. A total of 705 patients with first-ever stroke were included. Institutionalization, low levels of ADL and IADL (p mini-mental status up to 3 years after stroke (OR 2.69, 95% CI 1.2-5.8) as well as older age (p mini-mental status has an independent impact on long-term health outcome after stroke. Our results emphasize the importance of cognitive status screening to identify stroke survivors at risk and manage and treat these patients more efficiently.

A pilot study was conducted in 50 community-dwelling parkinsonian patients, in order to establish its metrological qualities. Comparisons were made with a neuropsychological battery including several tests widely used in the assessment of specific cognitive disorders in Parkinson’s disease. The correlations between the Mini-Mental Parkinson and each component of this battery were substantial, especially for the performance subtests of the WAIS-R (r = 0.62 to 0.72, the Stroop test (r = 0.65 the 15-objects test (r = 0.64, the word fluency (r = 0.63 and the Odd Man Out test (r = 0.61. The validity of each subtest of the Mini-Mental Parkinson was adequate except for one, based on a word choice, which requires a modification in French before definitive use. The test-retest reliability was high (r = 0.84. There was a significant difference in the mean scores in cases with confusional event (22.4, even without current signs of dementia, compared with patients with no such history (27.2. In conclusion, this brief test is suitable for assessment of parkinsonian patients.

    Cognitive decline is common in Parkinson's disease (PD) but may not be adequately identified by the mini-mental state examination (MMSE), which is better suited to Alzheimer's disease. The mini-mental Parkinson (MMP) examination is a cognitive screening tool designed in French specifically for PD. We aimed to establish the validity and reliability of the English language version of the MMP compared with the MMSE. People with various stages of PD underwent testing with the MMP and MMSE, which was then compared with a reference standard battery of neuropsychological tests to identify those with significant cognitive impairment. Forty-nine patients were recruited. Both the MMP and MMSE were significantly correlated with scores on all the neuropsychological tests in the validation battery. The median MMP score was proportionally lower (80% of maximum) than the MMSE (90% of maximum) in PD patients with cognitive impairment and those with prior neuropsychiatric complications but there was no difference between the MMP and MMSE in areas under the curves (0.84) for detecting cognitive impairment. Test-retest reliability of the MMP was good (intra-class correlation coefficient 0.793). An MMP of 28 or lower out of 32 detected cognitive impairment with 87% sensitivity and 76% specificity. The English language version of the MMP has now been validated. It detects more cognitive deficits in PD patients than the MMSE and identifies significant cognitive impairment in those with PD at least as well as the MMSE.

    It is a very well-known fact that an protonic exchange exists among natural DNA filaments and synthetic polynucleotides with the solvent (1--2). The existence of DNA open states, that is to say states for which the interior of the DNA molecule is exposed to the external environment, it has been demonstrated by means of proton-deuterium exchange (3). This work has carried out experiments measuring the dispersion of the traverse relaxation rate (4), as a pulsation rate function in a Carr-Purcell-Meiboom-Gill (CPMG) pulses sequence rate, to determine changes in the moist layer of the DNA molecule. The experiments were carried out under different experimental conditions in order to vary the probability that open states occurs, such as temperature or the exposure to electromagnetic fields. Some theoretical models were supposed to adjust the experimental results including those related to DNA non linear dynamic.

    Determining the ecological state or health of an ecosystem offers useful tools for its management and conservation. In Colombia, indexes of aquatic systems that combine in a single parameter the physical, chemical and biological variables have not been published, and the evaluation of water bodies' ecological state has been fragmentary or incomplete. In this work a limnological state index (LSI) for wetlands of the Canal del Dique, ecosystems under constant pressure by the human communities, is presented. For the construction of this multi-metric index, graphs of quality of the selected variables were constructed and values of importance were assigned to them. The theory of the multi-attributes was used to construct the LSI, which considers 12 variables. A principal components analysis was realized with these chosen parameters. A simplified version was designed (partial LSI - PLSI) in which four of the biological variables were excluded. Finally, an interpretation scale of the values obtained with these indices was built. The LSI and the PLSI were applied to wetlands of the Canal del Dique to establish their current ecological condition. Data show that the limnological state of most wetlands is acceptable, which suggests that these lentic ecosystems are within tolerable limits of function, although they are not exempt from deterioration processes.

    The International Challenge for Automated Prediction of MCI from MRI data offered independent, standardized comparison of machine learning algorithms for multi-class classification of normal control (NC), mild cognitive impairment (MCI), converting MCI (cMCI), and Alzheimer's disease (AD) using brain imaging and general cognition. We proposed to use an ensemble of support vector machines (SVMs) that combined bagging without replacement and feature selection. SVM is the most commonly used algorithm in multivariate classification of dementia, and it was therefore valuable to evaluate the potential benefit of ensembling this type of classifier. The ensemble SVM, using either a linear or a radial basis function (RBF) kernel, achieved multi-class classification accuracies of 55.6% and 55.0% in the challenge test set (60 NC, 60 MCI, 60 cMCI, 60 AD), resulting in a third place in the challenge. Similar feature subset sizes were obtained for both kernels, and the most frequently selected MRI features were the volumes of the two hippocampal subregions left presubiculum and right subiculum. Post-challenge analysis revealed that enforcing a minimum number of selected features and increasing the number of ensemble classifiers improved classification accuracy up to 59.1%. The ensemble SVM outperformed single SVM classifications consistently in the challenge test set. Ensemble methods using bagging and feature selection can improve the performance of the commonly applied SVM classifier in dementia classification. This resulted in competitive classification accuracies in the International Challenge for Automated Prediction of MCI from MRI data. Copyright © 2018 Elsevier B.V. All rights reserved.

    Harmonizing data across cohorts is important for validating findings or combining data in meta-analyses. We replicate and validate a previous conversion of MoCA to MMSE in PD. We used five studies with 1,161 PD individuals and 2,091 observations measured with both the MoCA and MMSE. We compared a previously published conversion table using equipercentile equating with log-linear smoothing to our internally derived scores. Both conversions found good agreement within and across the studies when comparing true and converted MMSE (mean difference: 0.05; standard deviation: 1.84; median difference: 0; interquartile range: -1 to 1, using internal conversion). These results show that one can get a reliable and valid conversion between two commonly used measures of cognition in PD studies. These approaches need to be applied to other scales and domains to enable large-scale collaborative analyses across multiple PD cohorts. © 2016 The Authors.

To assess the infl uence of habitual chocolate consumption over the MMSE in Spanish older adults. Cross-sectional study, using data of the follow-up of the Seniors-Study on Nutrition and Cardiovascular Risk in Spain (ENRICA) cohort. Habitual chocolate consumption in the last year was assessed with a computerized dietary history; differences between dark chocolate and milk chocolate were recorded. Chocolate intake was classified into the following categories: no consumption, chocolate consumption of ≥ 10 g/d had a better MMSE score (adjusted beta coefficient and 95% confidence interval: 0.26 (0.02-0.50; p trend = 0.05); for dark chocolate, the results were also statistically significant (0.48 [0.18-0.78]; p trend chocolate consumption was not associated with higher likelihood of having MCI. However, dark chocolate consumption was associated with less likelihood of MCI (OR and 95%CI for MMSE ≤ 25: 0.39 [0.20-0.77]; for MMSE ≤ 24: 0.26 [0.10-0.67]; and for MMSE ≤ 23: 0.25 [0.07-0.82]). Our results suggest that habitual dark chocolate consumption might improve cognitive function among the older population.

    Mental adjustment to cancer is known as a psychological, physical, and psychological health variable among cancer patients. The present study examines the factor structure and psychometric properties of the Mini-Mental Adjustment to Cancer scale (Mini-MAC) in a sample of Iranian adults who suffer from cancer. The sample consists of 320 cancer patients selected through non-random convenient sampling procedure from the hospitals and clinics in the cities of Kermanshah and Shiraz in Iran, using the Mini-MAC scale. One hundred of these patients also completed the Hospital Anxiety and Depression scale. Statistical methods used to analyze the data included confirmatory and exploratory factor analysis, discriminate validity, and Cronbach alpha coefficients for internal consistency. Factor analysis confirms five factors in the Mini-MAC. The values of fit indices are within the acceptable range. Significant correlations between the Mini-MAC and other measures also show that this scale has discriminate validity. Alpha coefficients for the subscales are Helplessness/Hopelessness,.94; Cognitive Avoidance.76; Anxious Preoccupation,.90; Fatalism,.77; Fighting Spirit.80; and total scale.84, respectively. The results confirm the five-factor structure of the Persian Mini-MAC scale and also prove that it is a reliable and valid scale. They show that this scale has sufficient power to measure different aspects of mental adjustment in patients with cancer.

    This study was aimed at finding out the changes in cognitive dysfunction in patients with traumatic brain injury (TBI) and investigating the factors limiting their cognitive improvement. Between January 2010 and March 2014, 33 patients with TBI participated in serial mini-mental status examination (MMSE). Their cognitive functions were statistically analyzed to clarify their relationship with different TBI status. Patients who developed hydrocephalus were separately analyzed in regards to their cognitive function depending on the placement of ventriculoperitoneal shunt (VPS). Bi-frontal lobe injury (β=-10.441, p<0.001), contre-coup injury (β=-6.592, p=0.007), severe parenchymal injury (β=-7.210, p=0.012), temporal lobe injury (β=-5.524, p=0.027), and dominant hemisphere injury (β=-5.388, p=0.037) significantly lowered the final MMSE scores. The risk of down-grade in the prognosis was higher in severe parenchymal injury [odds ratio (OR)=13.41, 95% confidence interval (CI)=1.31-136.78], temporal lobe injury (OR=12.3, 95% CI=2.07-73.08), dominant hemisphere injury (OR=8.19, 95% CI=1.43-46.78), and bi-frontal lobe injury (OR=7.52, 95% CI=1.31-43.11). In the 11 post-traumatic hydrocephalus patients who underwent VPS, the final MMSE scores (17.7±6.8) substantially increased from the initial MMSE scores (11.2±8.6). Presence of bi-frontal lobe injury, temporal lobe injury, dominant hemisphere injury, and contre-coup injury and severe parenchymal injury adversely influenced the final MMSE scores. They can be concluded to be poor prognostic factors in terms of cognitive function in TBI patients. Development of hydrocephalus aggravates cognitive impairment with unpredictable time of onset. Thus, close observation and routine image follow-up are mandatory for early detection and surgical intervention for hydrocephalus.

    There is a growing incidence of dementia patients in the community, and with this growth, there is need for rapid, valid, and easily administrable tests for the screening of dementia and mild cognitive impairment in the community. This review looks at the two most commonly used tests in dementia screening, namely, the clock drawing test (CDT) and the mini-mental status examination (MMSE). Both these tests have been used in dementia screening over the past three decades and have been the subject of scrutiny of various studies, reviews, and meta-analysis. Both these tests are analyzed on their ability to assess dementia and screen for it in the community, general practice and general hospital settings. The methods of administration and scoring of each test are discussed, and their advantages and disadvantages are explained. There is also a direct comparison made between the MMSE and CDT in dementia screening. Future research needs with these tests are also elucidated. PMID:29403122

    On the 21 of January of 2003, at 20:06:36 hrs (Mexico center time) an earthquake occurred at the Pacific coast with a magnitude of 7.6 degrees in the Richter scale, whose epicenter was located near the state of Colima and it was felt in a large extent of the Mexican Republic. The earthquake caused numerous material damages in the structures (houses, churches, offices, etc) and vital lines, mainly in the infrastructure of the electrical sector of the region, leaving without electrical energy a large part of the nearby populations and some colonies of distant zones such as in Mexico City. The cause of the interruption of the electrical energy was due to the collapse of some of the equipment of 400 and 230 KV of the electrical transmission substations, among which are Manzanillo II and Colima II. With the experience acquired in the earthquake of October 9, 1995 in Manzanillo, in which also the facilities and equipment of the electrical substations were affected considerably, and as a part of the infrastructure project on the analysis of seismic risk of vital lines that is being developed at this moment at the Instituto de Investigaciones Electricas (IIE), it was decided to inspect the electrical substations of the zone, where the greater damages in the facilities and equipment were reported, to analyze and to determine the main causes of their failure.

    To evaluate predictive validity of cognitive dysfunction of the Saint Louis University mental status (SLUMS) exam or mini-mental state exam (MMSE) for institutionalization and mortality after 7.5-years. Longitudinal study. Geriatric Research, Education and Clinical Center Veterans Affairs Hospital St. Louis, MO. Patients (N=705) were screened for cognitive dysfunction in 2003 using the SLUMS exam and MMSE, and mortality and institutionalization up to 7.5-years later were evaluated as outcome measures. The associations between outcome measures and MMSE and SLUMS exam total scores, and cognitive status were examined using Kaplan-Meier curves and Cox proportional-hazards regression. Five hundred thirty-three charts were reviewed, 176/533(33%) patients had died and 31/526 (6%) were institutionalized during 7.5-year follow-up period. All subjects were male with a mean age of 75 years and most had high school education or greater (71%). MMSE dementia, SLUMS dementia (ps<.001) and MCI (p<.05) groups had significantly lower survival rates than normal cognition group in the Kaplan-Meier curves. Scores classified as dementia on SLUMS (HR=2.4, 95% CI 1.6-3.7; p <.001) or MMSE (HR=2.3, 95% CI 1.5-3.6; p <.001) both predicted mortality and, also, institutionalization (SLUMS: HR=3.5, 95% CI 1.3-9.1; p <.01; MMSE: HR=3.8, 95% CI 1.6-9.0; p <.001) after adjustment for covariates. Unadjusted SLUMS exam MCI predicted morality (HR=1.5, 95% CI 1.1-2.2; p <.019) but not institutionalization. The SLUMS exam and MMSE both predict mortality and institutionalization for male patients screened as positive for dementia.

  4. Is the Mini-Mental State Examination (MMSE useful for eligibility screening of research participants with substance use disorder?

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Introduction: the MMSE is used for eligibility screening of potential research participants diagnosed with substance use disorder (SUD, as abilities needed to provide a valid informed consent or accurate information could be impaired in these clinical populations. Knowledge about the capacity of the MMSE to detect impairment in these abilities or at least to assess impact of SUD on its total score, however, is rather diffuse. This has important ethical and methodological implications. Objective: to analyze effects of SUD only, main substances of abuse, age of onset of substance use, recent substance use, and psychiatric comorbidity upon MMSE outcome. The overall purpose of the study was to assess the utility of the MMSE for eligibility screening of potential research participants with SUD. Method: individuals were recruited from residential facilities for substance use treatment. A demographic questionnaire, MMSE and Mini International Neuropsychiatric Interview were used. Results: A total of 601 participants were gathered for main analysis. Controlling for education, no differences in MMSE score were detected within main substances of abuse (F=1.25[4,529], p=.28, nor between SUD only versus SUD with psychiatric comorbidity (F=.58[1,597], p=.44. Effects of age of onset and recent use of specific substances upon MMSE score were also absent. Discussion and conclusions: If there is some cognitive impairment in this clinical population, it may not be pertinently assessed by the MMSE, thus casting doubt on its pertinence for eligibility screening.

    The biggest challenge regarding cognitive prospective evaluations in the elderly is the identification of subjects that go on to develop cognitive impairment. In this study, we compared the Italian telephone version of the MMSE (Itel-MMSE) with both the MMSE and a battery of neuropsychological tests in a group of 107 healthy elderly subjects. The aim of the study was to identify a subset of subjects who, despite having an overall score within the normal range, performed poorly in the cognitive neuropsychological evaluation. The Itel-MMSE score showed a good internal consistency as well as a significant correlation with the MMSE score, age and education. A score of < or = 21 on the Itel-MMSE was the score which reflected the highest degree of sensitivity in the neuropsychological tests. There was a statistically significant difference between subjects with an Itel-MMSE score of < or = 21 and those with a score of 22 in age, education, Attentional Matrices and Copying Drawings. Despite some potential limitations, our results strongly suggest that the Itel-MMSE may be used as a screening test to identify healthy elderly subjects whose cognitive performance is poor.

    The object of the study was to examine the factor structure and the psychometric properties of the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) among a large sample of Norwegian breast cancer patients. A total of 402 patients with breast cancer completed the Mini-MAC. Principal component analysis with varimax rotion confirmed four factors. Three had psychometric properties to the original Mini-MAC Helpless-Hopeless (HH), Anxious Preoccupation (AP) and Cognitive Avoidance (CA) subscales. The fourth, named Positive Attitude (PA) combined the Fighting Spirit (FS) and the Fatalism subscales of the original Mini-MAC. Construct validities were assessed by examining the interscale correlations as well as the correlations between the Mini-MAC subscales and the HADS subscales scores. Internal consistency of the five subscales was satisfactory for the original (HH, AP, CA, FA, coefficients=0.60-0.83), except for the FS subscale (coefficient=21). In view of the low internal reliability for the Norwegian Mini-MAC FS subscale coefficient; it appears to be more appropriate to use the Norwegian Mini-MAC as a four-factor model. If researcher or clinicians in Norway use the five-factor model, they should take great care when interpreting the fighting spirit subscale.

    Parkinson's disease (PD) is a chronic neurodegenerative disorder that causes cognitive impairment and dementia in ∼30% of patients. Compare metric qualities of Mini-Mental Parkinson (MMP) and scales for outcomes in Parkinson's disease-cognition (SCOPA-COG) with respect to their relative reliability, validity and ability to predict symptoms (mobility, quality of life, social repercussions, and mood) in PD patients. Outpatients (n=123, 78 males/45 females) diagnosed with PD were included in the study. A multilevel (hierarchical) modeling analysis was performed along with tests of reliability and validity to ascertain which of the two models better predicts symptoms related to PD. The MMP differed significantly between patients with Hoehn and Yahr (H&Y) stages 1, 2 or versus 4/5 (grouped together). The SCOPA-COG showed differences only between patients in H&Y stages 2 versus 4/5. Both scales were dependent on educational background and age. The SCOPA-COG had a higher coefficient of variation (0.303) than the MMP (0.184), indicating that it was the more discriminative of the two. The SCOPA-COG has some advantages over the MMP, the most important being a greater discriminative ability. Multilevel hierarchical analysis clarified the necessity of stratifying the PD population according to educational background, years of illness, and H&Y stage when using these scales. © 2010 Movement Disorder Society.

    Full Text Available El trabajo se encuadra en el marco de un trabajo mayor sobre la conformación del Estado santiagueño, a partir de la caída de los Taboada, en 1875, hasta la llegada del radicalismo al poder, en 1916. Esta etapa, a la que denomino de consolidación del Estado, corresponde al período final en la que el Estado provincial, delineado a fines del siglo XIX, comenzó a fortalecerse, como consecuencia de la llegada al poder de una nueva élite, compuesta por intelectuales, que centraban sus negocios en la propia organización estatal. Es posible identificar una mayor definición del Estado y el afianzamiento de proyectos institucionales a expensas del predominio de sectores de la burguesía intelectual, imbuidos de ideas positivistas en boga, ligados también a actividades agrícolas-comerciales. Nuevos problemas, como la mayor urbanización, las enfermedades sociales y otros que tienen que ver con la necesidad de ejercer más control sobre la sociedad, hicieron que la burguesía gobernante asumiera, desde el Estado, nuevos roles que condujeron a consolidar al propio Estado en formación. El Estado como órgano recaudador perfeccionó los mecanismos de previsión de gastos a través de los presupuestos y de la sanción de leyes impositivas con el propósito de paliar, en parte, el atraso material de la provincia. La organización de la administración fue perfeccionándose. Como hipótesis de la etapa analizada se considera que la consolidación y modernización del Estado, si bien se produjo con mayor resolución en el ámbito de las decisiones políticas, en los mecanismos de socialización e incorporación persistieron formas y modos de prácticas vigentes, con características de mayor duración, combinándose dinámicamente, en consecuencia, factores de continuidad-cambio.The work is framed within a larger research of the formation of the Santiago del Estero's State since the family Taboada lost their power, in 1875, to the arrival to office of

    This work is carried out in Veracruz State covering over 11 jurisdictions of the State (Panuco, Tuxpan, Poza Rica, Martinez de la Torre, Xalapa, Cordoba, Orizaba, Veracruz, Cosamaloapan, San Andres Tuxtla and Coatzacoalcos). The sampling was realized in a period from 2009 to 2013 analyzing home drinking water, supply sources and wells, the sampling was done by the sanitary checkers of different jurisdictions with approved methods and the methodology was validated at the State Laboratory of Public Health. 1637 samples were analyzed by counting equipment Tennelec Canberra series 5 and a gas supply system P-10 with calibration curves for alpha and gross beta. The results of measurements ranging from 0.07 to 0.25 Bq/L in the activity concentration gross alpha annual average, an gross beta were from 0.12 to 0.17 Bq/L in the activity concentration gross beta annual average, and with a concentration range of alpha activity up to 0.62 and a minimum 0.02, and the concentration of beta activity of a maximum value 1.54 and a minimum 0.02, taking also as resulted in five years of analysis only 1.16% of the analyzed samples (19 samples) showed a value of alpha activity concentration above the minimum detectable concentration and 62.43% (1022 samples) of the analyzed samples showed a value of beta activity concentration above the minimum detectable concentration, is also clear that the results of the sanitary jurisdictions of Panuco and Tuxpan not have corresponding activity values for the years 2009, 2011-2013 except 2010. We can conclude that the regular measurements of alpha and gross beta activity in water are invaluable for timely detection of radioactive contamination. (Author)

    Full Text Available La determinación de la posición angular instantánea del rotor es parte integral del control en los accionamientos de Motores de Reluctancia Conmutada. La medición directa de esta variable adiciona complejidad y costo al sistema y no siempre brinda buenos resultados, lo que ha motivado el desarrollo y prueba de algoritmos de estimación de la posición angular del rotor. En este trabajo se presenta el empleo de un Filtro Desaromatizado de Kalman para estimar la velocidad y la posición angular del rotor del motor MFR 132.5, basado en un modelo de caja gris de dicho motor que también es presentado en este trabajo. Los resultados demuestran que este estimador ofrece estimaciones satisfactorias del estado del motor, lo mismo durante el arranque que durante el funcionamiento regular, aún bajo la presencia de perturbaciones en el torque de la carga y errores en la estimación inicial de la posición angular del rotor.  The measure of the instant angular position of the rotor is integral part of the control of Switching Reluctance Motors drivers. The direct measurement of this variable adds complexity and cost to the system and it doesn’t give good results sometimes. That has motivated the development and test of algorithms for estimating the rotor angular position of the motor. In this work is presented the use of an Unscented Kalman Filter for estimating the speed and rotor angular position of the motor MFR 132.5, based on a grey box model of the motor which is also presented in this work. The results show that this kind of estimator gives good estimations of the state of the motor, as well during the starting as during the regular operation, even under the presence of perturbations of the load torque and errors in the initial estimation of the angular position.

    Normative data for the Tygerberg Cognitive Battery (TCB) and Mini-Mental Status Examination (MMSE) (in South Africa) have not been formally examined before. The TCB was developed for the bedside pen-and-paper screening of cognitive impairment in each of the 6 main cognitive domains, including attention and concentration, speech, memory, praxis, gnosis, and executive functioning. The test is also used to diagnose different neuropsychiatric conditions. The MMSE is an established screen of cognitive status, which is often used as a comparative standard for novel screening tests such as the TCB. The TCB was initially developed in English and Afrikaans, and a Xhosa version was also initiated with this study so that the 3 most common languages of the region could be accommodated. The first aim of the study was to estimate normative test performance on the TCB and MMSE among controls, and the second aim was to develop a Xhosa version of the TCB. Assessments of the TCB and MMSE were carried out in a population of healthy individuals (n = 157). In addition, healthy Xhosa-speaking participants (n = 14) were screened using a Xhosa version of the TCB. Reliability scores for all forms of the TCB were satisfactory. Age and education correlated significantly with TCB scores (r = -0.26, P < .01; r = 0.64, P < .01, respectively), whereas only education significantly correlated with MMSE scores (r = 0.32, P < .05). Normative values were calculated accordingly, that is, controlled for the effects of age and education. The TCB scores also correlated significantly with MMSE scores (r = 0.49, P < .05), demonstrating the potential of the TCB to serve as an alternate cognitive assessment tool, along with the MMSE, to focus neuropsychiatric investigations. Scores on the Xhosa version differed significantly on speech, praxis, and gnosis between the Afrikaans and English participant scores. These normative data can be used to increase precision and to provide an impartial evaluation when

    Full Text Available A review about nopol synthesis is included in this contribution. The traditional methodologies include the thermal synthesis and the use of ZnCl2 asa catalyst, and the emergent processes are the heterogeneous catalytic processes. The use of catalysts based on Sn supported on mesoporous materials,as reported by the Environmental Catalysis Research Group 10 years ago, iswidely discussed. Among the reported procedures, the homogeneous catalytic processes have the disadvantage of costs associated with separation andtreatment of inorganic salts generated during the processes. The commercialalternative for nopol production by heterogeneous catalytic processes shouldinclude reduction of costs associated with the production and regenerationof the catalysts. It should also include the minimization of the solvent required for compensating the requirements of time and energy associated withthe thermal process with respect to the moderate reaction conditions of theheterogeneous catalytic processes.En esta contribución se hace una revisión de los métodos para la síntesis delnopol.

    The Mini-Mental Adjustment to Cancer Scale (Mini-MAC) is a 29-item instrument designed to evaluate the responses developed by cancer patients during their mental adjustment to diagnosis and treatment. This study aims to validate the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) translated and adapted to the Portuguese language and culture, in end-of-life cancer patients receiving palliative care. The instrument was administered to 346 Portuguese end-of-life cancer patients, receiving care through outpatient visits or admitted into palliative care units, without cognitive symptoms and with symptoms under control. A cross-sectional validation study using orthogonal rotation through the varimax method followed by convergent and discriminant validity. The analysis of the main components confirms the existence of five factors, demonstrating the validity of the construct, with good internal consistency in the subscales and Cronbach's alpha values between 0.78 and 0.93. Good test-retest reliability was also found, and r values for subscales ranged from 0.62 to 0.99. The instrument proved to be a reliable, valid and sensitive measure in the study of mental adjustment of Portuguese end-of-life patients with cancer receiving palliative care. Nurses can use the Mini-MAC Scale in research and clinical practice in order to evaluate the mental adjustment of Portuguese end-of-life cancer patients receiving palliative care.

    Full Text Available Si bien existen estructuras del Estado, que no sólo de gobierno, cuya misión es impulsar y proteger los derechos ciudadanos, es claro que ésta no siempre se cumple cabalmente. Desde la formulación de leyes, políticas públicas, y regulaciones que deben hacer efectivas ambas, y entre todas éstas y su ejecución para asegurar el impacto deseado, existen con frecuencia brechas que terminan por hacerlas inoperantes. El caso de las medidas que a lo largo de muchos años se han establecido para el control del tabaco en México es un claro ejemplo de ello. En efecto, en múltiples ocasiones en el pasado se tomaron medidas de diversa índole que por una u otra razón han sido inefectivas. El postulado central de este ensayo es que desde el diseño de una ley, una política pública, y el logro de su propósito, intervienen necesariamente los fundamentos sobre los cuales se construyó esa política, su pertinencia a las necesidades que le dieron origen y las estructuras que la crean y/o las que deben hacerse responsables no sólo de acatar la ley y de convertirla en una política operativa sino de asegurar que esa operatividad se concrete en logros demostrables en los plazos esperados y con los recursos necesarios. El Consejo de Salubridad General se fortalece y rescata su vocación primigenia para responder como una de las estructuras del Estado que debe contribuir, con otras más, a la articulación de la génesis, formulación y ejecución de políticas públicas para que éstas transiten de un desideratum hacia una realidad de efectos positivos demostrables.Not always public policies for the advocacy of citizen rights meet their goal, among other things, because between their formulation and their implementation there is a lack of appropriate structures to generate, articulate and execute these policies.

La noción de poder político (o control social es central en esta aproximación: tomando como punto de partida “las áreas de dominación y oposición” que existen en el seno de las relaciones sociedad-estado, mira en particular las diferentes fuerzas en la sociedad que intentan monopolizar los tres mbitos que se asocian tradicionalmente al rendimiento estado moderno: el monopolio sobre la violencia, la asignación de recursos económicos y la representación de una población más o menos “fija”. Aunque claramente más afín a perspectivas más orientadas a la sociedad, la visión presentada intenta sin embargo combinarlas con un modelo más integrador de las relaciones estado-sociedad, que sirve para analizar cómo los estados y las sociedades siguen constituyéndose y transformándose el uno al otro, en un contexto de debilitamiento de las capacidades estatales.In the aftermath of 9/11, the problem of state ‘collapse’ appears again on  he agenda as an important question of global security. Nevertheless, the academic discussion has not come much further than post conflict dynamics of interference of various new ‘orders’ that move beyond traditional state capacities. The discussion on state collapse thus seems to be placed in a growing deadlock between classical state-centrist approaches —which keep pointing at functional problems— and more society-oriented insights that try to explain other political and economic loyalties that have emerged in the

    Full Text Available The water supply is currently a problem, given the over-exploitation of groundwater and contamination of surface water, so it is important to find alternative supplies. The rain water harvesting is considered one of the most viable options for the supply of the vital liquid; some of the most utilized systems for this purpose are the jagüeyes. State Park General Lázaro Cárdenas del Río better known as "Flor del Bosque", it is located east of the city of Puebla and listed as Protected Natural Area, this park has jagüeyes which store water from rain. In this research, the main physicochemical and microbiological parameters of water stored in four jagüeyes of “Flor del Bosque” were measured according to Mexican regulations, in order to establish its quality and determine the uses that are given as a watering wooded areas and drinking trough do not represent a risk to the flora and fauna of the park. Composite samples of each jagüey were analyzed, during two dry weather stations and two rainy weather stations between the moths of November 2011 and October 2012. The water of the four jagüeyes has microbiological contamination by helminth eggs, Fasciola hepatica, fecal (180 CFU and total coliforms (475 CFU, this represents a risk to the health of wildlife; as well as lots of settleable and suspended solids. Since these systems have been installed for watering wooded areas and drinking trough of animals live there, it would be advisable before use be given appropriate treatment, plus it aims to improve its design or construction to be suitable for the intended uses.

  11. Determination of the load state of lead-acid batteries using neural networks; Determinacion del estado de carga de baterias plomo-acido utilizando redes neuronales

    The charge of lead-acid batteries (LAB), as in any other type of batteries, consists of replacing the energy consumed during the discharge. Nevertheless, as no physical or chemical process is good enough to totality recharge a battery, it is necessary to supply to it more than the 100% of the energy demanded during its discharge. A critical factor to make a suitable load control of the batteries is to determine its own state of load. That is to say, to have an efficient load control, it is necessary to count on means that allow to accurately determining the residual capacity of the battery to deliver load. This one is the one of the aspects of greater interest in the research centers around world. For this reason, in this work it was pretended to develop a calculation algorithm of the state of load of batteries based on a fuzzy-neural network that could calculate the state of load without using the battery current as an input. This is because one of the main problems for the designers of battery load controllers is the correct supervision of the current that circulates around the system in all the rank of operation of the same one because the sensors do not have a linear behavior. [Spanish] La recarga de baterias plomo-acido (BPA), como cualquier otro tipo de baterias, consiste en reponer la energia consumida durante la descarga. Sin embargo, como ningun proceso fisico o quimico es lo bastante eficiente para recargar a totalidad una bateria, es necesario suministrarle mas del 100% de la energia demandada durante su descarga. Un factor critico para realizar un adecuado control de carga de las baterias, es determinar su propio estado de carga. Es decir, para tener un control de carga eficiente, es necesario contar con un medio que permita determinar con precision la capacidad remanente de la bateria para entregar carga. Este es uno de los aspectos de mayor interes en los centros de investigacion alrededor el mundo. Por tal razon, en este trabajo se propuso

    Nowadays Research and Development activities on Solar Thermal Power Generating Systems are supported by some countries around the world. Because of their thermal nature each of these plants can be operated only with solar energy or can be hybridized (solar/fossil fuel) and also with thermal storage systems. These types of solar thermal power plants are: Central Receiver, a circular field of tracking mirrors called helisotats reflects the solar energy onto receiver mounted on top of a central tower. Parabolic Trough, use linear parabolic concentrators to reflect sunlight to a receiver along the focal line (metallic pipe). Inside the pipe solar energy is absorbed in a working fluid with temperatures up to 390 Celsius degrees, which is then piped to a central location to power a conventional steam turbine and Parabolic Dish uses a parabolic dish concentrator to focus solar energy to a receiver and a heat engine/generator, located at the focus of the dish, to generate electrical power. In this document, we present the current status of technologies. A description of market opportunities, cost and technological perspectives are also included.

The wetland has had numerous trophic changes because the anthropogenic activities carry on the area (sugar mills, farmers, etc., This study determined the trophic state of the wetland using biological parameters such as primary productivity, chlorophyll, riparian flora and aquatic macro invertebrates, as well as physical and chemical such as water temperature, salinity, dissolved gases and others. According to our data, we determined that the wetland has a eutrophic state prone to hyper eutrophication. The system is continuously subjected to disturbance by human activities that change the characteristics of the ecosystem. As an indicator of this change, it is noticeable that in some sectors the marshy vegetation shows succession process belonging to a transition between aquatic and terrestrial ecosystems. For this reason, it is important the get more and meaningful knowledge of their successional stage in order to implement actions that will enable their restoration and conservation.

    The Mini-Mental Adjustment to Cancer Scale (Mini-MAC) is widely used to evaluate cancer patients' psychological responses. Validation studies of the scale have shown methodological shortcomings and inconsistency in the factor solutions. The aim of this study was to examine the factor structure and psychometric properties of the Mini-MAC. A large sample of 364 Chinese patients with breast or colorectal cancer completed the Mini-MAC and psychosocial measures (general health, perceived stress, anxiety, and depression). Exploratory factor analyses examined the relative fit of two- to six-factor models using robust weighted least square estimation and oblique target rotation. Convergent validity was evaluated via correlations between the Mini-MAC factor scores and the psychosocial outcomes. The five-factor model showed the best model fit and largely replicated the original Mini-MAC's helpless/hopeless (HH), anxious preoccupation (AP), fighting spirit (FS), fatalism (FA), and cognitive avoidance (CA) subscales. The five factors had acceptable reliability (Cronbach's α = 0.67-0.88) and 4-month test-retest reliability (r = 0.45-0.64). HH, AP, and CA were positively associated with the psychosocial outcomes (r = 0.19-0.60). Modest and negative correlations were found between the psychosocial outcomes and FS and FA. The results support the Mini-MAC's original five-factor structure with satisfactory reliability and convergent validity. The results demonstrate that the Mini-MAC is a valid measure for assessing psychological responses in cancer patients.

    We evaluate the influence of surgery for unruptured aneurysms on cerebral blood flow and neuropsychological estimate. We evaluated the cases of 28 consecutive patients with unruptured cerebral aneurysm treated with direct surgery accompanied by craniotomy. Before and after surgery, MRI, 123 I-IMP-SPECT with 3D-SSP analysis and MMSE were performed. There was not a significant decrease in MMSE. In 123 I-IMP-SPECT, it was recognized that the cerebral blood flow was decreased at the frontal operculum of operative site. These results indicate that careful neuropsychological evaluation is essential to make a favorable treatment plan for unruptured aneulysms. (author)

    es una herramienta clave para la rectoría del sistema de salud. Al adoptar este enfoque, otros países podrán elegir intervenciones con base en criterios de accesibilidad, efecto en la salud de la población, efecto en desigualdades de salud y en la capacidad para medir dichos efectos. Para alcanzar el éxito en este tipo de análisis comparativo del desempeño a nivel subnacional, las instituciones nacionales que lo lleven a cabo deberán contar con autoridad, habilidades técnicas, recursos e independencia suficientes.Benchmarking of the performance of states, provinces, or districts in a decentralised health system is important for fostering of accountability, monitoring of progress, identification of determinants of success and failure, and creation of a culture of evidence. The Mexican Ministry of Health has, since 2001, used a benchmarking approach based on the World Health Organization (WHO concept of effective coverage of an intervention, which is defined as the proportion of potential health gain that could be delivered by the health system to that which is actually delivered. Using data collection systems, including state representative examination surveys, vital registration, and hospital discharge registries, we have monitored the delivery of 14 interventions for 2005-06. Overall effective coverage ranges from 54.0% in Chiapas, a poor state, to 65.1% in the Federal District. Effective coverage for maternal and child health interventions is substantially higher than that for interventions that target other health problems. Effective coverage for the lowest wealth quintile is 52% compared with 61% for the highest quintile. Effective coverage is closely related to public-health spending per head across states; this relation is stronger for interventions that are not related to maternal and child health than those for maternal and child health. Considerable variation also exists in effective coverage at similar amounts of spending. We discuss the

    An experiment was conducted at Merowe Research Station farm, in the Northern State, Sudan, during 2008/2009 and 2009/2010 seasons. The objectives of the experiment were to determine the damage inflicted by a wild sorghum species (Sorghum arundinaceum (Del.) Stapf. ) on the yield of faba bean (Vicia faba L.) and to evaluate the efficacy of the post-emergence herbicide clodinafop-propargyl (Topik) on wild sorghum and its effect on faba bean yield. The wild sorghum reduced faba bean crop stand and straw and seed yields by 53% - 76%, 76% - 79% and 88% - 91%, respectively, compared with the hand-weeded control. Faba bean was tolerant to the herbicide. The herbicide, at all rates, effected complete (100%) and persistent control of the wild sorghum and resulted in faba bean seed yield comparable to the hand-weeded control. The lowest dose (0.075 kg a.i/ha) of the herbicide used was equal to 75% of the dose recommended for the control of wild sorghum in wheat. It is concluded that clodinafop-propargyl at 0.075 kg a.e/ha could be used in controlling wild sorghum in faba bean. At this rate, the marginal rate of return was about 35 which indicating that every monetary unit (SDG 1) invested in the mentioned treatment would be returned back, plus additional amount of 35 SDG.(Author)

    Cognitive deficits, self-reported or found following electroconvulsive therapy (ECT), and their correlates are diverse. Despite the characteristics of people receiving ECT in Asia differ widely from the west, pertinent research from Asia remains sparse. We investigated the correlates of self-reported, mini-mental status examination (MMSE) defined, and autobiographical memory deficits in a cohort that received ECT in a south Indian tertiary-care setting. 76 consecutive consenting people were recruited within seven days of completing their ECT course. Memory was assessed by a subjective Likert scale, MMSE, and an autobiographical memory scale (AMS). Psychopathology was assessed by brief psychiatric rating scale, and serum cortisol levels were estimated by chemi-luminescence immunoassays. Relevant sociodemographic and clinical data were collected from the participants, and their medical records. The correlates were analysed using generalised linear models after adjusting for the effects of potential confounders. Self-reported, MMSE-defined, and autobiographical memory deficits were present in 27.6% (95%CI 17.6-37.7%), 42.1% (95%CI 31.0-53.2%), and 36.8% (95%CI 26.0-47.7%) of participants, respectively. Agreement between the memory deficits was poor. Age, less education, duration of illness, hypothyroidism, and past history of another ECT course were significantly associated with MMSE-defined deficits. Age, anaemia, past ECT course, and pre-ECT blood pressure were significantly associated with autobiographical memory deficits, while residual psychopathology and cortisol levels were significantly associated with self-reported memory deficits. Self-reported, MMSE-defined, and autobiographical memory deficits are common at the completion of ECT course, and their correlates differ. All service users receiving ECT need periodic cognitive assessments evaluating multiple cognitive domains. Copyright © 2018 Elsevier B.V. All rights reserved.

    The elderly population is increasing around the world, and the prevalence of dementia increases with age. Hence, it is expected that the number of people with dementia will increase significantly in the coming years. The Mini-Mental Status Examination - 2 (MMSE-2) and Mini-Cog are widely used tests to screen for dementia. These scales have good reliability and validity and are easy to administer in clinical and research settings. The purpose of this study was to validate the Arabic versions of MMSE-2 and Mini-Cog. These scales were assessed against the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision ( DSM-IV-TR ) criteria for dementia, as the gold standard. The standard versions of the MMSE-2 and Mini-Cog were translated to Arabic following the back-translation method. Then, a trained rater administered these tests to 134 Arab elderly aged >60 years. A physician, blind to the results of these two tests, assessed the participants for vascular dementia or probable Alzheimer's disease, based on the DSM-IV-TR criteria. The sample included 67.2% Qataris. The mean age was 74.86 years (standard deviation =7.71), and 61.9% did not attend school. The mean of the adjusted scores of MMSE-2 based on age and education level was 19.60 (standard deviation =6.58). According to DSM-IV-TR , 17.2% of the participants had dementia. Sensitivity and specificity of the MMSE-2 and the Mini-Cog together were 71.4% and 61.6%, respectively, which were better than those of each test alone. Together, the Arabic versions of MMSE-2 and Mini-Cog are good screening tools for cognitive impairment in Arabs.

    The mini-Mental Adjustment to Cancer Scale is designed to assess psychological responses to cancer diagnosis and is widely used in research and clinical practice. Recent evidence demonstrates adequate convergent validity but inconsistent internal consistency and factor structure. This study aimed to provide a parsimonious factor structure with clinical utility. Repeated measures data were collected from 160 cancer patients (mixed illness type) at diagnosis and 3-month follow-up. Principal axis factoring with oblimin rotation was used. The number of factors was decided using parallel analysis. The resultant factors were compared against the recommended five-factor structure on internal consistency (Cronbach's alpha) and test-retest reliability and convergent validity (Pearson's correlation). Parallel analysis suggested that a four-factor model optimally fits these data. Two of these-cognitive avoidance and fighting spirit-are equivalent to the original factor structure. Redistribution of the remaining items resulted in factors of cognitive distress and emotional distress. Internal consistency and test-retest reliability of the new four-factor structure are equivalent, but convergent validity is much improved overall when compared with a five-factor structure, with the exception of the fighting spirit factor. The revised four-factor structure represents a more psychometrically sound measure of psychological adjustment in the current dataset. Findings related to the larger cognitive distress factor are congruent with data from foreign-language validation studies. The brevity of this improved measure may make it easier to administer in the clinical setting. Copyright © 2011 John Wiley & Sons, Ltd.

    Mental adjustment and coping affect the physical outcome and survival as well as quality of life in cancer patients. The Mini-Mental Adjustment to Cancer (Mini-MAC) scale is a new refined, economical and reliable self-rating instrument measuring cognitive and behavioral responses to cancer. The aim of this study was to evaluate the psychometric properties of the Mini-MAC in Korean cancer patients. A total of 208 cancer patients recruited from the Yonsei Cancer Center were assessed with the Mini-MAC and the Hospital Anxiety and Depression Scale (HADS). Principal component analysis with varimax rotation for the Korean version of Mini-MAC (K-Mini-MAC) confirmed four factors. Three had psychometric properties similar to Helpless-Hopeless (HH), Anxious Preoccupation (AP) and Cognitive Avoidance (CA) of the original Mini-MAC. A novel factor, named Positive Attitude, included items of both Fatalism (FA) and Fighting Spirit (FS) from the original version. The five subscales from the original version (AP, HH, FS, FA and CA) and Positive Attitude had acceptable internal reliabilities in our sample (Cronbach's alpha coefficient 0.50-0.86; correlation coefficient of test-retest 0.68-0.88). For the validity, significant interscale correlation was observed in the original five subscales and Positive Attitude. Each subscale including Positive Attitude was also significantly related to Depression and Anxiety of HADS. As a whole, the K-Mini-MAC was a reliable, valid and acceptable tool for Korean cancer patients. These findings can provide information about the cross-cultural validity of Mini-MAC scale's factor structure. Cultural differences were also discussed.

    Full Text Available La energía potencial del agua presenta diferencias de un punto del suelo a otro; esas diferencias son las que originan el movimiento del agua de acuerdo a la tendencia universal de la materia en el sentido de moverse de donde la energía potencial es mayor a donde dicha energía es menor. En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

    Full Text Available En los últimos años ha habido grandes controversias y debates sobre la eficacia de diferentes métodos de detección del cáncer de mama. En un esfuerzo por proporcionar orientaciones más claras tanto a las mujeres como a los profesionales de la salud, un grupo de expertos reunido por el Gobierno de los Estados Unidos de América, el llamado U.S. Preventive Services Task Force (USPSTF, publicó en febrero de 2002 un informe en el que se afirma que la mamografía permite salvar vidas y que su realización debería comenzar en la quinta década de la vida de la mujer. Este grupo de expertos dice también que no hay datos suficientes para hacer recomendaciones a favor o en contra de otros dos métodos de detección: el examen clínico de la mama y la autoexploración mamaria rutinaria. El presente documento resume las recomendaciones del informe del USPSTF, así como las principales consideraciones clínicas y pruebas científicas que presentó en áreas como la exactitud y fiabilidad de las pruebas de detección, la eficacia de la detección temprana del cáncer de mama, cuándo detener el tamizaje, el intervalo de tiempo más apropiado entre las pruebas y los potenciales perjuicios del tamizaje.

    Riassunto. L'analisi è stata condotta al fine di valutare l'effetto sia sulla sopravvivenza globale (OS) sia sulla sopravvivenza libera da progressione di malattia (PFS) della chemioterapia di combinazione in prima linea per il carcinoma pancreatico in fase avanzata di malattia. La presente analisi è limitata agli studi randomizzati controllati (RCT) di fase III. Successivamente è stata applicata la European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) agli RCT di fase III analizzati per ricavare uno score relativo all'entità del beneficio clinico ottenuto per ciascun RCT. Sono state calcolate inoltre le differenze in termini di PFS tra i diversi bracci di trattamento rapportandole con i costi dei farmaci necessari per ottenere il beneficio di PFS. La nostra analisi ha valutato 11 RCT di fase III, per un totale di 4572 pazienti. Combinando i costi della terapia con la misura dell'efficacia espressa dalla PFS, è stato ottenuto un costo di 74,12 euro (€) per mese di vita guadagnato in termini di PFS con la combinazione di 5-fluorouracil, leucovorin, irinotecan e oxaliplatino (FOLFIRINOX), 90,14 € per la combinazione di gemcitabina e oxaliplatino (GEMOX) e 4708,7 € per la combinazione di nab-paclitaxel e gemcitabina. Da questo punto di vista riteniamo che l'utilizzo delle "vecche chemioterapie di combinazione" (per es., GEMOX) non dovrebbe essere completamente abbandonato, ma valutato sul singolo paziente, sulla base di diversi fattori (età, ECOG PS, comorbilità, carico di malattia), al fine di ottenere una reale "tailored therapy".

    The effect of roasting time on the contents of bioactive compounds (tocopherols, phytosterols, phenolic compounds), antioxidant capacity and physicochemical properties of rapeseed oil pressed from de-hulled seeds was investigated. The de-hulled seeds were roasted at a temperature of 165 °C for 20, 40, 60, 80, and 100 min. The results of this study show that a roasting pre-treatment led to a gradual increase in canolol content (from 1.34 to 117.33 mg/100 g), total phytosterols (from 573.51 to 609.86 mg/100 g) and total carotenoids (0.82 to 2.41 mg/100 g), while only slight changes in the contents of tocopherols were noted. With the increase in roasting time a gradual increase in oxidative stability (from 4.27 to 6.85 h), and antioxidant capacity, seen mainly in the hydrophilic fraction of oil (from 0.32 to 2.30 mmol TEAC/l) was found. Although roasting resulted in the formation of primary and secondary oxidation products, the quality parameters of oils were within Codex Alimentarius limits. [Spanish] Se estudió el efecto del tiempo de tostado sobre el contenido de compuestos bioactivos (tocoferoles, fitoesteroles, compuestos fenólicos), capacidad antioxidante y propiedades fisicoquímicas del aceite de prensado de semillas descascarilladas de colza. Las semillas descascarilladas se tostaron a una temperatura de 165 ºC durante 20, 40, 60, 80 y 100 min. Los resultados de este estudio muestran que el pretratamiento con tostado condujo a un aumento gradual del contenido de canolol (de 1,34 a 117,33 mg/100 g), fitosteroles totales (de 573,51 a 609,86 mg/100 g) y carotenoides totales (0,82 a 2,41 mg/ 100 g). Sólo se observaron ligeros cambios en el contenido de tocoferoles.

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

    The initial temperatures field is presented for 40 wells in the Los Humeros geothermal reservoir, along with an elevation curve based on the formation temperature or the most probable reservoir temperature. Stabilized temperatures were estimated using the Radial Spherical Heat Flow method, chosen over the Horner method based on the numerical simulation of the circulation and stop processes of well H-26. In this well, the last temperature log series was reproduced, considering circulation losses. The temperatures were used to produce isothermal curves over three geological sections of the field, which represent the initial distribution of temperatures in the reservoir and show the thermal characteristics and the relationships among thermal anomalies and faults in the reservoir. The elevation curve plotted against the initial temperature of the formation was generated based on detection of the main feed zones at each well, which in turn was developed using detailed analyses of diverse information, such as temperature logs, circulation losses, lithology, well completion, and heat velocities. Based on the results, two groups of wells may be distinguished: one between 1000 and 1600 masl with temperatures from 290 to 330 degrees Celsius, and one between 900 and 0 masl with temperatures from 300 to 400 degrees Celsius.

    Purpose: Little information is available on the importance of pretreatment Mini-Mental Status Exam (MMSE) on long-term survival and neurologic function following treatment for unresectable brain metastases. This study examines the importance of the MMSE in predicting outcome in a group of patients treated with an accelerated fractionation regimen of 30 Gy in 10 daily fractions in 2 weeks. Materials and Methods: The Radiation Therapy Oncology Group (RTOG) accrued 445 patients to a Phase III comparison of accelerated hyperfractionated (AH) radiotherapy (1.6 Gy b.i.d.) to a total dose of 54.4 Gy vs. an accelerated fractionation (AF) of 30 Gy in 10 daily fractions from 1991 through 1995. All patients had histologic proof of malignancy at the primary site. Brain metastases were measurable by CT or MRI scan and all patients had a Karnofsky performance score (KPS) of at least 70 and a neurologic function classification of 1 or 2. Two hundred twenty-four patients were entered on the accelerated fractionated arm, and 182 were eligible for analysis (7 patients were judged ineligible, no MMSE information in 29, no survival data in 1, no forms submitted in 1). Results: Average age was 60 years; 58% were male and 25% had a single intracranial lesion on their pretherapy evaluation. KPS was 70 in 32%, 80 in 31%, 90 in 29%, and 100 in 14%. The average MMSE was 26.5, which is the lower quartile for normal in the U.S. population. The range of the MMSE scores was 11-30 with 30 being the maximum. A score of less than 23 indicates possible dementia, which occurred in 16% of the patients prior to treatment. The median time from diagnosis to treatment was 5 days (range, 0-158 days). The median survival was 4.2 months with a 95% confidence interval of 3.7-5.1 months. Thirty-seven percent of the patients were alive at 6 months, and 17% were alive at 1 year. The following variables were examined in a Cox proportional-hazards model to determine their prognostic value for overall survival

    Full Text Available Between July 2004 and June 2005, 84 specimens of Lithobates brownorum (Sanders, 1973 were collected and examined for helminths. Hosts came from 3 localities in the state of Yucatán, Mexico: Celestún (n= 35, Lagunas de Yalahau (n= 33, and Ría Lagartos (n= 16. Twelve helminth taxa were found: 7 nematodes, 4 digeneans, and 1 acanthocephalan. With the exception of Haematoloechus floedae and Megalodiscus temperatus, all helminth taxa found have a Neotropical distribution. Our results differ from those obtained in previous studies dealing with amphibians in Mexico because we found higher richness and abundance of nematodes than digenean species. The relatively low mean intensity and mean abundance values reached by digenean species in this study may be related to the generalist host diet and with the vagility of frogs (from the aquatic to the terrestrial environment or vice versa.Entre julio del 2004 y junio del 2005, se recolectaron y examinaron 84 ejemplares de Lithobates brownorum (Sanders, 1973 en busca de helmintos en 3 localidades del estado de Yucatán: Celestún (n= 35, Lagunas de Yalahau (n= 33 y Ría Lagartos (n= 16.

Nuestros resultados difieren de los obtenidos por otros autores que han reportado más especies de digéneos que de nematodos en este grupo de hospederos. Los bajos valores de intensidad y abundancia media de los digéneos encontrados en este estudio pueden estar relacionados con la amplia dieta del hospedero y la vagilidad que éste presenta entre el medio acuático y el terrestre.

El análisis propone una visión de conjunto sobre las discusiones que se llevaron a cabo en torno a su realización y la respuesta que provocó en los principales líderes étnicos. Integra dos sectores fronterizos sobre los que se proyectaba avanzar -la frontera sur de Córdoba, Mendoza y San Luis y la frontera bonaerense- y las agrupaciones nativas más cercanas a esos espacios: los ranqueles y los salineros dirigidos por el cacique Calfucurá.The aim of this paper is to analyze the context during 1869-1872 when the central government attempted to carry out the military conquest of the Southern Indian Territory established by Law 215, issued in 1867. An overview of the discussions taken place around war conduct and the resistance of ethnic leaders are presented. It integrates two main border areas on which the conquest was expected: the southern border of Córdoba, Mendoza and San Luis and Buenos Aires and the strategies of the indigenous groups closer to these spaces: the ranqueles and the salineros.

    Full Text Available The return of the Bourbons in 1814, despite the accompanying aggressive program of the extreme right-wing, intended to break the centralized state apparatus, considered to be the very source of "revolutionary danger”, by no means involved a reduction inthe power on an administration that has been poorly purged. Ultra-realism quickly showed itself unable to stabilize the economy and the society by means of a historic compromise that was nonetheless quickly organized by a technocracy composed of an combination of the old pre-1789 France offices and those of the revolutionary and imperial times. Under the lessons of Turgot and Colbert, the State became guardian and supervisor of a type of economic and social liberalism that provided French industrialization with new vigour. It also fostered and the creation of a protected national market. This modernising identity of the State managed to evolve. It overcame the right-oriented turn of politics promoted by Villèle. In order to meet the challenges of the French modernization process from 1828, the State decided to mirror the "English methods”, thus making the rigidity of the Napoleonic administration evolve. | El regreso de los Borbones en 1814, a pesar del agresivo programa de extrema derecha que trajo consigo, según el cual pretendía acabar con el aparato del Estado centralizado por considerarlo la fuente misma del “peligro revolucionario”, no mermó en ningún caso el poder de una administración que había sido muy poco depurada. El realismo ultra rápidamente demostró su incapacidad para estabilizar la economía y la sociedad mediante un compromiso histórico que, sin embargo, fue rápidamente organizado por una tecnocracia compuesta por una fusión de los despachos de la Francia anterior a 1789 y los del episodio revolucionario e imperial. Entre lecciones de Turgot y de Corbert, el Estado se hizo el guardián y el tutor de un liberalismo económico y social que dotó de un nuevo

    Full Text Available Objective: To determine the relationship between state size (measured in terms of public spending and public health indicators in a sample of countries representing all regions of the world and from 1990-2000. Methods: An ecological study was performed using data on Central Government Spending (CGS and per capita Gross National Product (GNP obtained from the International Monetary Fund, and on life expectancy, maternal, and infant mortality, provided by the World Health Organization. A multiple linear regression model was fitted to estimate the effect of CGS on health, which also took into consideration per capita GNP and geographical region. Results: CGS varied little over the study period, with convergence around an average of 28%, but within a relatively wide range (7.80-53.0%; the countries with the strongest economies (according to per capita GNP had the highest levels of CGS. The influence of this factor was particularly relevant for the infant mortality rate (r = 0.40; beta = -1.327; EE = 0.237; t = -5.590; p Objetivo: Determinar la relación entre el tamaño del Estado (medido como el gasto público y los indicadores de salud en una muestra de países de todas las regiones del mundo, en la década de los noventa.

    Full Text Available The wastewater treatments with floating macrophytes have proven effective in the remediation of waters with nutrient content, organic matter and toxic substances such as arsenic, zinc, cadmium, copper, lead, chromium, and mercury. Its importance lies in its ability to be used in rural communities due to their low consumption of conventional energy and practicality in the assembly and operation of treatment systems. Still, it has not been clarified thoroughly the processes taking place in the purification of wastewater with floating macrophytes. This article attempts to review the existing literature on floating macrophytes, thus identifying the general aspects, advantages and disadvantages of using these plants for treating wastewater. Similarly, identify the most important background since the beginning of this application. There will be described models and design criteria mostly employed, rigorously reviewing removal efficiencies of different species of floating macrophytes. Finally it will be addressed as discussed current perspectives and future challenges for the development of this technique.Los tratamientos de aguas residuales que involucran macrófitas flotantes han demostrado ser eficientes en la remediación de aguas con contenidos de nutrientes, materia orgánica y sustancias toxicas como arsénico, zinc, cadmio, cobre, plomo, cromo, y mercurio.

    Full Text Available Local government is a basic mainstay for democratic Welfare States based on principle of maximum closeness to the citizen (subsidiarity. However, municipalities are faced with many problems to make this challenge, including precisely its limited financial capacity and infra municipalism. Therefore, they had to devise new ways to maximize administrative efficiency of tax administration and collection. Following the literature on models of local public service delivery, local tax management provision would be: direct supply by the local administration, delivery through special purpose bodies dependent on the local government, and outsourcing. These formulas, incorporating elements of both the New Public Management (NPM and governance, have been reflected in various models ranging from inter administrative cooperation and supra local organizing skills. The aim of the study is to analyze these formulas for the sake of the principles of Solidarity, Equity and Redistribution. In this sense, municipalities have to maximize tax revenue for effective development of their social policies in the mode of Welfare States increasingly uncertain.

    Full Text Available Sobre todo desde los trabajos de Daniel Kahneman y Amos Tversky, la psicología económica se consolida como disciplina. Esos autores muestran que la racionalidad económica con frecuencia no se cumple a cabalidad. Resultado de esas constataciones se plantea si dado que el sujeto puede perjudicarse con sus decisiones le corresponde al Estado decidir por él. Esta cuestión acarrea la discusión de si el paternalismo de Estado, aún el blando, no menoscaba la libertad y por ende el desarrollo mismo de un sujeto responsable ¹ . En este trabajo ubicamos algunos ejemplos y los términos de la discusión. En las conclusiones planteamos que es la propia dinámica del mercado, al pasar de una etapa a otra, más que una iniciativa individual, la que corrige esas irracionalidades. Por último analizamos en que condiciones la intervención del Estado no socava la libertad del individuo o incluso puede fortalecer las posibilidades de un sujeto responsable.Behavioral economics has now become a major new field in economic. Daniel Kahneman and Amos Tversky backed up by a large amount of experiments; show that rationality in standard economy is not always accomplished by the decision maker. Due to these experiments the discussion is the following: if the individual can harm himself by making his own decision, then should the State make the decision on what is best for the individual? This subject matter leads to the controversy on paternalism: Does it diminish freedom as a value and so the development of the responsible citizen? In this paper we will set some examples of the discussion currently held in the academic world. Last we will show how the historic market dynamic can modify the irrational behavior. We will also set some precision on when not only the state intervention doesn't diminish freedom but also can enforce the experience of consumption of the responsible citizen.

    Full Text Available The 1992 Constitution recognizes the existence of people prior to the formation of the Paraguayan State and in that sense it gives them certain rights that protect their territory, identity and culture. This declaration of purpose constitutes a break with the previous model of dominant and exclusionary state policies toward indigenous peoples. However, the rights of indigenous peoples continue without respected, in spite of the space won in terms of social and political organizations, the struggle continues in this constant «search of the land without evil». This paper aims to describe the current situation of indigenous peoples from an analysis of access to public services, economic status, employability, employment discrimination and public policy. It also attempts to explain the factors that have influenced in the lack of consolidation of the indigenous movement in Paraguay.La Constitución Nacional de 1992 reconoce la existencia de pueblos anteriores a la conformación del Estado paraguayo y, en ese sentido, les otorga una serie de derechos que protegen sus territorios, identidad y cultura. Esta declaración de intenciones constituye un quiebre con respecto al modelo anterior de políticas estatales dominantes y excluyentes hacia los pueblos indígenas. No obstante, los derechos de los pueblos indígenas siguen sin respetarse, y a pesar de los espacios ganados en cuanto a organizaciones sociales y políticas, la lucha continúa en esa búsqueda constante de la tierra sin mal. Este trabajo busca describir la situación actual de los pueblos indígenas a partir de un análisis del acceso a los servicios públicos, la situación económica, la empleabilidad, la discriminación laboral y las políticas públicas. Asimismo, intenta explicar los factores que han influido en la escasa consolidación del movimiento indígena en Paraguay.

En la doble dimensión, por una parte, de la libertad personal para profesar un determinado credo religioso, o no profesar ninguno, o abandonar el que se profesa o cambiar de creencias. Y, por otra parte, de la libertad social que consiste en la protección y ausencia de coacción o limitaciones a la hora de actuar y manifestarse públicamente en consecuencia con la fe profesada. Reflexión que realizamos con especial referencia al caso español. Estudiamos el régimen de libertades establecido y consolidado en la Constitución de i 978 y desarrollado, en un primer momento, por la vigente Ley Orgánica de Libertad Religiosa.

    Full Text Available Currently, the service quality is the biggest distinguishing factor and the most powerful competitive advantage of service companies, where the performance of the human factor is fundamental. For the study of service quality two fundamental props exist: the internal and the external clients. The present investigation analyzes the service quality of fast food businesses from the participation of the avant-garde employee, in the specific case of businesses located in Libertador Municipality of Merida State, Venezuela. For this purpose, the integral model of quality breaches of the service and the scale of Dineserv were applied during the second semester of 2014. In this regards, a representative sample of the population of managers, employees and external customers of fast food businesses was selected, and a survey was applied to each of them. Compliance with the standards of the service employees was verified, as well as the positive correspondence between this performance and the levels of quality of service perceived by the user. To confront the low perception of the performance of the employee, rewards, recognition and multiple and varied stimulus should be implemented in order to motivate for a continuous improvement of the quality of service.

Utilizando la metodología del análisis de discurso se tiene como objetivo contrastar las narrativas regeneradoras en torno a la catástrofe del estado con los discursos académicos contemporáneos construidos en torno a la patología e insuficiencia del aparato público. Pese a sus aparentes diferencias ideológicas, el discurso político del siglo XIX y la narrativa académica contemporánea, muestran fuertes coincidencias, como reacciones a una ausencia simbólica de autoridad o fuerza de gobierno. La autora concluye con una reflexión en torno a la historicidad de las narrativas académicas, identificando el discurso de la patología del estado como una Regeneración deslocalizada.The article shows an historical character of the academic narratives that qualify the existence of the state as absent, weak or failed. Using the methodology of discourse analysis, the article aims to compare the regenerative narrative about the disaster in the state with contemporary academic discourses built around the pathology of the public apparatus and the failure of the state. Despite their apparent differences in ideology, these political discourses of the nineteenth century and the contemporary academic narrative show surprising coincidences. These convergences can be interpreted as strong reactions to a symbolic absence of authority and public force in the Colombian context. The author concludes with a reflection on the historical character of the academic narratives.

This study compares the usefulness of Montreal Cognitive Assessment (MoCA to Standardized Mini-Mental Status Exam (SMMSE for diagnosing mild cognitive impairment (MCI in Type 2 diabetes mellitus (DM population. Methods. This prospective pilot study enrolled 30 community dwelling adults with Type 2 DM aged 50 years and above. Subjects were assessed using both the SMMSE and MoCA for MCI. In all subjects, depression and dementia were ruled out using the DSM IV criteria, and a functional assessment was done. MCI was diagnosed using the standard test, the European consortium criteria. Sensitivity and specificity analysis, positive and negative predictive values, likelihood ratios and Kappa statistic were calculated. Results. In comparison to consortium criteria, the sensitivity and specificity of MoCA were 67% and 93% in identifying individuals with MCI, and SMMSE were 13% and 93%, respectively. The positive and negative predictive values for MoCA were 84% and 56%, and for SMMSE were 66% and 51%, respectively. Kappa statistics showed moderate agreement between MoCA and consortium criteria (kappa = 0.4 and a low agreement between SMMSE and consortium criteria (kappa = 0.07. Conclusion. In this pilot study, MoCA appears to be a better screening tool than SMMSE for MCI in the diabetic population.

    The state of Chihuahua counts with at least 56 uranium zones or of minerals associated to this, being Pena Blanca the greatest and more important deposit of the country. Some of the main cities of the state are near to these deposits, as Aldama and Chihuahua. Its were took samples of soil of 11 cities of the state to determine the natural activity of radionuclides. It was determined the specific activity attributable to the parents of the series of {sup 238} U, {sup 232} Th, and of the {sup 40} K isotopes, as well as effective dose rate H{sub E} in the soil samples. It was used the high resolution gamma spectrometry of a high purity Ge detector in the laboratory of Environmental Radiological Surveillance of the CIMAV. The measure of the activity of the uranium series carries out by means of the lines of 351 KeV of the {sup 214} Pb and of 609 keV of the {sup 214} Bi, while the thorium series it was deduced of the lines of 238 keV of the {sup 212} Pb and of 912 keV of the {sup 228} Ac. Its were carried out copies and replies for the quality control. Its were found high values of specific activity of some radionuclides, in the near cities to uranium deposits like Aldama and Chihuahua. For the cities that are not near to deposits, as Ciudad Juarez and Ojinaga, the found values were normal. Also the effective dose rate was high for the near cities to deposits like Aldama, Bocoyna, Chihuahua, Jimenez and Nuevo Casas Grandes, it is also necessary to determine, the radon in air levels and of radionuclides in consumption water to obtain the dose that the population of those populations receives.

    Migration across international borders places tremendous stress on immigrant families and may put women at greater risk for intimate partner violence. In this study, we used narrative analysis methods to explore how nine Mexican immigrant women in the Northeastern United States described their experiences of intimate partner sexual violence, and how these stories were embedded within narratives of transition and movement across borders. We identified three major themes: The Virgin and the Whore, The Family, and Getting Ahead. We share important implications for researchers and health and social service providers working with this population. © The Author(s) 2016.

Aunque en Cuba se fabrican transformadores de distribución, no existe unaguía para tratar este problema, pero cada día urge más establecer una política a seguir desde el punto devista de proyección y en busca de una explotación eficiente. Se pretende en este trabajo, abordar el temaexponiendo los resultados investigativos que existen  en el mundo sobre el mismo y tratando de aportar unpunto de vista que pueda ayudar a abrirse paso entre lo ya estudiado y hacer una propuesta.  One of the topics that at the moment is occupying the world of the designers and exploiters of transformersit is that of the operation of these teams with non lineal loads, producers of distortions or harmonic in thesigns of tension and current. Among the problems caused by the harmonic, the additional generation oflosses and of heating in the transformers, it is among the most important. If the load that these teams feed,stays constant, the result is the loss of useful life of the transformer, among other problems that can bepresented. A solution very employee in many countries for this problem, is the reduction of the capacity ofthe transformers, that is to say, the

    Full Text Available Since the passage of the North American Free Trade Agreement in 1993, there has been an increasing need to monitor environmental health trends that may be related to the rapid industrialization of the United States/Mexico border. We studied two counties on the California/Baja California border to obtain baseline data on trends in childhood asthma hospitalizations and two pollutants that aggravate asthma, ozone and particulate matter (less than 10 microns in diameter, from 1983 to 1994. Hospital discharge records of children 14 years and younger were analyzed, and rates by county, race, and sex were age-adjusted to the 1990 California population. Data on five ozone and particulate matter indices obtained from the California Environmental Protection Agency were used. Imperial County had the highest childhood asthma hospitalization rates in California for non-Hispanic whites and African-Americans, and the second highest for Hispanics. San Diego County had rates below the state average. Over the time period examined, rates in Imperial County increased 59%, while those in San Diego County decreased 9%. Maximum ozone levels increased 64% in Imperial County but decreased 46% in San Diego County. Particulate matter levels were four times higher in Imperial than in San Diego County. High rates of childhood asthma hospitalizations in Imperial County may be partially related to high levels of poverty and worsening air quality conditions produced by increased burdens on the local airshed. Asthma prevalence surveys and binational time-series analyses examining asthma-pollutant relationships are needed.Desde que se firmó el Tratado de Libre Comercio en 1993, ha aumentado la necesidad de monitorear problemas de salud que podrían relacionarse con la rápida industrialización de la frontera mexicana-estadounidense. Estudiamos dos condados de la fontera entre California y Baja California con objeto de obtener datos de base sobre las tendencias observadas de

    This report reviews the state of the art and the future trends of post occupancy evaluation. POE analysis is a systematic assessment process of the operation of a facility (typically a building) once they have been occupied by its users, and focuses on the needs of the occupants, in an attempt to measure whether the design of building suits the needs of its users. Historically, POE arises in the context of the study of Environment and Behaviour (Environment and Behaviour Research), an interdisciplinary academic movement from the fi eld of psychology that emerged in the United States due to the increased environmental awareness of the 60's. The main objective of this movement was to introduce the environmental variable (and fi nd out their influence) in the relationship between the individuals and their behaviour. The post occupancy assessment considers the need of end-user opinion to assess whether the operation of the building and the strategies employed in the design of it, are having the desired effect. Therefore, Post Occupancy Evaluation allows exploring the impact of sustainable strategies in the experience and comfort of users. (Author) 68 refs.

    This research was carried out with the object to recover the existing uranium in the copper-uranium deposit of Luz del Cobre located at 1300 Kms. approximately of the NW of Mexico City in the state of Sonora this deposit is geologically formed by a partially mineralized chimney which contains 572,732 tons of uranium ore with an average of 362.26g. of U 3 O 8 per ton, which represents 207,374 tons of U 3 O 8 in situ. To recover the uranium from this deposit, the only technical and economical possibility which presents a real interest is the system of leaching in situ. This operation will consist in the selective dissolution of the copper and uranium through leaching solution with a pH varying from 2.2 to 2.5, leaving the gangue on the ground and collecting the enriched solutions at the lower level of the mine, precipitating the copper subsequently through scrap iron and recovering the uranium from the tails of the copper precipitation plant through an ionic interchange process in counter current and its subsequent elution solvent extraction, reextraction and precipitation. This system makes possible to recover an uranium concentrate up to 98% of U 3 O 8 and practically free from impurities. The production cost would cost exceeding $300.00 Mexican currency per Kg of U 3 O 8 . (author)

    Full Text Available Between october 2013 and june 2015, a solid waste pilot recycling program was applied in six educational units located in Juan Antonio Sotillo and Diego Bautista Urbaneja counties, Anzoátegui state, Venezuela. The program was designed for its implementation in schools with educational levels from kinder garden to high school, with the purpose of contributing to environmental education for developing awareness on preservation of the environment and natural resources. The main objective of this study was to evaluate the program. For developing the program, undergraduate students participated as a human resource along with the authors, schools personnel and schools students. During two consecutives phases, a series of activities were performed to achieve the proposed goals. Some of the most significant were environmental education for recycling and its practice. Data were collected by direct observation, structured interviews, questionnaire and on-site measuring techniques. Results reflected that students had a better response during the first phase of the program, with respect to participation and materials recovering. In addition, it was observed that preschool and elementary school students had the best response to the program application. Motivation was one of the main factors that influenced on the results. The lack of a municipal recycling program could also have influenced over the results.

Metodología: se analizó la información sobre mortalidad del Sistema Nacional de Información en Salud (sinais. La unidad de análisis fue la causa básica de la defunción codificada según la décima revisión de la CIE. La mortalidad evitable fue clasificada según el catálogo de causas de muerte propuesto por Gómez. Se hizo un análisis exploratorio de la relación entre la mortalidad evitable y la derechohabiencia y el nivel socioeconómico de los municipios correspondientes a las muertes. Resultados: la tasa de mortalidad evitable global fue de 350,2 muertes por mil habitantes en la región. La mortalidad evitable por diagnóstico y tratamiento médico precoz, violencia y VIH/SIDA tuvo tasas de 223, 60 y 5 por mil habitantes, respectivamente, presentando variaciones de magnitud, sociodemográficas y por derechohabiencia entre estados. Discusión y conclusiones: las poblaciones de los estados de la frontera norte de México se caracterizan por tener una dinámica sociodemográfica y de los servicios de salud muy intensa. Los resultados sugieren que el sistema de salud está siendo rebasado en su respuesta a una alta frecuencia de enfermedades no transmisibles. En el aspecto social existen condiciones estructurales en México que favorecen la presencia de narcotráfico y su consecuente causa de violencia y consumo de drogas ilegales que podrían estar relacionadas con la frecuencia de muertes violentas y en forma subsidiaria con las causadas por el VIH/SIDA. / ABSTRACT Objective: to analyze avoidable mortality between 1998 and 2007 in the border states of Northern Mexico to evaluate, indirectly, the quality of the region's health care services.

    To establish the discriminatory validity of the mini-mental test (MMSE) and the memory alteration test (M@T) for the diagnosis of amnestic mild cognitive impairment (aMCI) and probable Alzheimer's disease (AD), and also to study the association between the results obtained in screening tests, a neuropsychological battery and a functional questionnaire in healthy persons and in patients with aMCI and AD. We evaluated 27 normal controls, 27 patients with aMCI and 35 patients with AD using the MMSE and a memory screening test, the M@T, a neuropsychological battery and a questionnaire on functional activities of daily living. Pearson correlation coefficients were used to evaluate the relations between the scores on the M@T and the MMSE and the neuropsychological tests. The area below the curve, the sensitivity and the specificity were calculated for the screening tests. In patients with aMCI, the scores on the M@T and the MMSE were strongly associated with the performance in the episodic memory tests in frontal tests and with the scores on the functional questionnaire, but not with tests that evaluated praxias and perceptive functions. In patients with AD, the scores on the M@T and the MMSE were associated with results in semantic memory, language, executive functions and praxias, but not with perceptive tests and functional questionnaires. In patients with aMCI and AD, the association between MMSE and M@T only correlate with some cognitive functions, without there being any association with other cognitive functions. Therefore, screening tests cannot be used as the only instrument for evaluating the cognitive status in patients with suspected dementia.

    Full Text Available La nutrición es un requisito elemental de la condición humana, su afectación genera un estado de desnutrición energético-proteica que se acompaña de diversas manifestaciones clínicas, grados de intensidad y evolutividad, lo cual le confiere el carácter de complejo sindrómico. Teniendo en cuenta la repercusión en el desarrollo físico general del niño, así como la importancia de un adecuado desarrollo del aparato estomatognático durante los primeros años de vida, nos propusimos el objetivo de determinar la relación existente entre el estado nutricional y las principales afecciones bucales. Para ello, se realizó un estudio con 52 escolares de enseñanza primaria, escogidos según un estudio previamente realizado por Medicina General Integral; de ellos, 26 fueron normo peso y 26 con trastornos nutricionales; de estos últimos, 14 delgados y 12 bajo peso. Los niños se examinaron a la luz natural en sus escuelas. Las variables analizadas fueron edad, estado nutricional, los índices coe-d y COP, la presencia de maloclusiones, así como el índice de PMA. Se encontraron elevados los índices de coe-d y COP en los niños con trastornos nutricionales (coe-d 1,50 y COP 0,66, mientras que en los normopeso fueron de 0,73 y 0,53, para el coe-d y el COP, respectivamente. Se observó alta prevalencia de maloclusiones en los bajo peso con 66,6 %, 46,15 % en los normopeso, y un elevado porcentaje de gingivitis en niños delgados y bajo peso (14,28 y 16,66, respectivamente, mientras que en los normopeso fue de 23,07.Nutrition is an essential requisite of the human condition.

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

To assess the validity of recommendations for use of the 85th and 95th percentiles of body mass index (BMI of the population in the United States of America as a screening tool to assess overweight/obesity in adolescents. Methods. We investigated the relation between BMI and percent body fat in 1 540 adolescents (717 males and 823 females aged 10 to 17.9 years old from a private high school in Niterói, a city in the state of Rio de Janeiro, Brazil. We used bioelectric impedance, with the appropriate equations for adolescents, to estimate percent body fat, which served as the gold standard (30% for girls and 25% for boys to calculate the sensitivity and specificity of the 85th and 95th percentiles of the United States and Brazilian distribution curves of BMI. Results. Sensitivity and specificity were high (above 80% for the Niterói boys, except for the 85th percentile of the Brazilian curve (specificity = 61.8% and for the 95th percentile of the United States curve (sensitivity = 55.4%. For the Niterói girls, the 85th- and 95th-percentile BMI cutoff points, from both the United States and Brazilian curves, showed low sensitivity, and that sensitivity decreased with age. Specificity was high for the girls, and much higher than it was for the boys. Conclusions. These data suggest that using BMI to screen for overweight/obesity in adolescents can generate a high percentage of false-positives for Niterói boys and an even higher percentage of false-negatives for Niterói girls. A more universal approach to using anthropometric measures to screen for overweight/obesity should be developed, preferably linked to stages of maturation.Objetivos.

    Full Text Available Abstract Background The mini-Mental Adjustment to Cancer Scale (mini-MAC is a well-recognised, popular measure of coping in psycho-oncology and assesses five cancer-specific coping strategies. It has been suggested that these five subscales could be grouped to form the over-arching adaptive and maladptive coping subscales to facilitate the interpretation and clinical application of the scale. Despite the popularity of the mini-MAC, few studies have examined its psychometric properties among long-term cancer survivors, and further validation of the mini-MAC is needed to substantiate its use with the growing population of survivors. Therefore, this study examined the psychometric properties and dimensionality of the mini-MAC in a sample of long-term cancer survivors using Rasch analysis. Methods RUMM 2030 was used to analyse the mini-MAC data (n=851. Separate Rasch analyses were conducted for each of the original mini-MAC subscales as well as the over-arching adaptive and maladaptive coping subscales to examine summary and individual model fit statistics, person separation index (PSI, response format, local dependency, targeting, item bias (or differential item functioning -DIF, and dimensionality. Results For the fighting spirit, fatalism, and helplessness-hopelessness subscales, a revised three-point response format seemed more optimal than the original four-point response. To achieve model fit, items were deleted from four of the five subscales – Anxious Preoccupation items 7, 25, and 29; Cognitive Avoidance items 11 and 17; Fighting Spirit item 18; and Helplessness-Hopelessness items 16 and 20. For those subscales with sufficient items, analyses supported unidimensionality. Combining items to form the adaptive and maladaptive subscales was partially supported.

    The Venta de Carpio Terminal is located in the Northern part of the old Texcoco Lake, State of Mexico, in highly compressible soil. In it, it is received, regulated, measured and distributed natural gas, LP gas and PEMEX Refinacion products that are supplied to distribution terminals of and consumption centers located in the central area of the country, that encompasses the states of Puebla, Tlaxcala, Mexico, Hidalgo, Queretaro and a small part of the Federal District. The construction of the Venta de Carpio station dates from 1960; since then, it has presented important regional settlements, mainly due to the water extraction of the subsoil, that have imposed deformations to the piping systems connected to the surface facilities that have been piloted in the terminal. Equally, other surface piping systems and facilities present deformations by differential settlement between their supports. [Spanish] La Terminal Venta de Carpio se ubica en la parte norte del antiguo Lago de Texcoco, Estado de Mexico, en terreno altamente compresible.

La construccion de la estacion Venta de Carpio data de 1960; desde entonces, se han presentado asentamientos regionales importantes debidos, principalmente a la extraccion de agua del subsuelo, que han impuesto deformaciones a los sistemas de tuberias conectados con las instalaciones superficiales que han sido piloteadas en la terminal. De igual modo, otros sistemas de tuberias e instalaciones superficiales presentan deformaciones por hundimientos diferenciales entre sus apoyos.

    Full Text Available Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

Estudio desarrollado a sabiendas de la importancia que reviste el sistema electoral como un medio que permite a los ciudadanos convertir su voto expresado en las urnas en escaños a favor de determinado candidato o partido. En dicho análisis tomamos en cuenta la evolución constitucional del sistema electoral mexicano, la participación de las fuerzas minoritarias en la integración del Senado y de la Cámara de Diputados, la división que se hace del territorio en circunscripciones electorales, la barrera electoral que se fija a los partidos políticos para acceder a la representación en el Parlamento, la fórmula de asignación que se aplica a la votación obtenida, para finalmente concluir que el sistema electoral mexicano es esencialmente mayoritario aun cuando se vista de proporcional.

The critical index of soil compaction is obtained with the Proctor test. The objective of this work was to perform a physical comparison between the Uhland sampler, with free and forced fall of the hammer, and the Proctor apparatus to assess mechanical alterations of the sample. Standard and modified Proctor instruments were used, as well as the Uhland with free and forced hammer fall. A completely randomized statistical design with ten replicates and four treatments was performed along with the analysis of variance, Minimum Significant Differ­ence and polynomial regression. It was concluded that Uhland and Proctor instruments pro­duced similar results. The penetrating energy of the Uhland was higher than the compacting energy of the Proctor. Humidity in the soil had an influence of the apparent dry density. The solidity ratio of the soil and the air porosity were the parameters that best identified the compaction process for the Proctor and Uhland instruments.

    La doctora MarthaLucía Tamayo comparte muchas inquietudes alrededor del Libro del Almismo, el Libro del Pensar; de dónde salió ese nombre; de juntar en medicina y en genética a tres escritores como lo son Jorge Luis Borges, Macedonio Fernández y Julio Cortázar. Su conferencia dice así:

    El término almismo fue ideado por Macedonio Fernández porque defendía mucho el ensimismamiento y el pensamiento hacia el interior, mirar hacia adentro; cada uno somos un “sí mismo” que nos hace diferentes aunque al mismo tiempo podemos ser iguales. Todos tenemos esa parte interior que la medicina debe trabajar y que no puede olvidar.

    “El Libro del Almismo, el libro del pensar” nos lleva a replantear y a repensar un poco la medicina que queremos, una medicina vuelta a pensar.

    Quiero contarles la historia de cómo se llegó a este libro y por qué y para qué se sigue trabajando en estos temas: Después de mi internado y de un trabajo un poco triste de rural, volví al Instituto de Genética y a la Universidad Javeriana en donde encontré al doctor Bernal y un espacio que estaba buscando para esa medicina diferente que quería, con un grupo de personas que me permitía no sólo ver la medicina sino ver muchas otras cosas más; había espacio para la literatura, para Mafalda, para hablar de niños, de locos, había incluso tiempo para hablar de medicina dentro del golf, de carros antiguos y de todo eso fui aprendiendo.

    Eso era lo que estaba buscando. Una medicina que diera espacios diferentes, que fuera más humanizada. Rápidamente me ubiqué y me quedé! No me arrepiento en lo absoluto de haberme quedado porque fue, ha sido y sigue siendo, una experiencia enriquecedora, de muchas vivencias importantes. Sabía exactamente dónde estaba y sabía que había que seguir rápido y había que trabajar muchos aspectos de esa medicina que estábamos buscando y de esa genética especial.

    Los cambios del nivel del mar han ejercido una fuerte influencia en la evolución del planeta y en la historia de la humanidad. En una escala de tiempo geológico, las variaciones de los niveles oceánicos han dejado un registro ampliamente distribuido en la forma de depósitos sedimentarios. El descenso del nivel del mar durante la Ultima Glaciación, que alcanzó unos 120 metros hace 18.000 años, permitió la emergencia del estrecho de Bering y la migración humana desde Eurasia hacia América.

    Full Text Available A partir de un texto del poeta Octavio Paz llamado «La imagen», se busca proseguir la equivalencia entre las imágenes de la poesía y la función que ellas tienen para el poeta, y el fantasma fundamental y su función para el analizante que está en el momento del pase. Se parte de la idea de que la poesía busca entrar en el ser así como el psicoanálisis tiene como finalidad apuntar al corazón del ser del sujeto. Se hace entonces una distinción del concepto de «ser» para el psicoanálisis, haciendo alusión también al discurso de la filosofía. Esclarecido el sentido de lo que es el «ser» para el psicoanálisis, se aborda de lleno – entre otras cosas, relacionadas con la experiencia del pase específicamente- la equivalencia entre la definición que hace Octavio Paz de «La Imagen» y el momento del pase en el análisis de un sujeto, imagen que, al igual que el mito para la filosofía, las leyes para la ciencia y el matema para el psicoanálisis, se constituyen en los instrumentos con los que cada una de estas disciplinas horadan en lo real.

    Full Text Available OBJETIVO: Caracterizar la violencia de pareja e identificar los principales factores que se asocian a la violencia en el embarazo en cuatro estados de alta marginación en México. MATERIAL Y MÉTODOS: La fuente de información fueron los datos de la Encuesta Nacional sobre Violencia contra las Mujeres 2003. Con base en ésta se realizó un estudio transversal, donde se incluyeron 1 949 mujeres entre 15 y 50 años de edad, que alguna vez estuvieron embarazadas y que demandaron atención en los servicios de primer y segundo nivel de atención de la SSA, IMSS e ISSSTE de los estados de Guerrero, Hidalgo, Oaxaca y Chiapas durante el periodo noviembre 2002- marzo 2003. Mediante regresión logística simple y múltiple, se evaluó la asociación entre las variables de interés y la violencia en el embarazo. RESULTADOS: Del total de mujeres, 250 (13% informaron haber sufrido violencia (física, psicológica, sexual y económica durante alguno de sus embarazos; una de cada tres refirió haber recibido golpes en el abdomen durante el embarazo. En la mayor parte de los casos (91.4% el agresor fue el cónyuge. Las variables que se asociaron positivamente con violencia en algún embarazo fueron: a nivel de escolaridad de la mujer: las analfabetas, comparadas con las mujeres que tenían escolaridad superior a primaria completa, presentaron la asociación más fuerte (RM 2.2; IC 95:% 1.1, 4.4; b antecedentes de violencia en la niñez (RM 3.2; IC 95% 1.9, 5.4; c antecedentes de abuso sexual antes de los 15 años (RM 2.4, IC95% 1.3, 4.4 y d consumo diario de alcohol por la pareja (RM 6.5; IC 95% 3.3, 12.9. CONCLUSIÓN: Los resultados de este estudio muestran que la violencia durante el embarazo es un hecho frecuente en contextos de alta marginación, además de que su expresión tiende a ser más severa. Los resultados sustentan la necesidad de seguir estudiando el problema de la violencia en el embarazo en México, además de identificarlo durante el proceso

    The Cerro Prieto Geothermal Field (CPGF) steam transportation network is constituted by 140 km of pipes with diameters ranging from 8 to 48 inches, which transport the steam of 165 producing wells to 13 power plants which have a total installed capacity of 720 MWe. Originally, the pipes are thermally insulated with a mineral wool or fiber glass layer and an external aluminum or iron cover. Due to the insulation material has been exposed to weather conditions during the field operation it shows nowadays different grades of wear-out, or even it is lacking in some parts of the network, causing higher heat losses from the pipes to the environment. In this work, the magnitude of the heat losses related with the present condition of the thermal insulation throughout the pipeline network is assessed. This involved determining the longitude and diameter, as well as the insulation condition of each single pipeline section, and the calculation of the heat transfer coefficients for the different thermal insulation conditions defined for this study. [Spanish] La red de transporte de vapor del campo geotermico Cerro Prieto (CGCP) esta constituida por aproximadamente 140 km de tuberias de 8 a 48 pulgadas de diametro, las cuales conducen el vapor producido por 165 pozos hacia 13 plantas generadoras, cuya capacidad instalada es de 720 MWe. Originalmente, estas tuberias son aisladas termicamente con una capa de 2 pulgadas de material aislante a base de lana mineral o fibra de vidrio, y una proteccion exterior de aluminio o hierro. Debido principalmente al impacto de las condiciones meteorologicas durante el tiempo de operacion del campo, en algunas porciones de la red el aislante presenta actualmente distintos grados de deterioro, o incluso se encuentra ausente, lo cual se traduce en una mayor perdida de calor desde las tuberias hacia el medio ambiente. En el presente trabajo se evalua la magnitud de las perdidas de calor asociadas al estado fisico del aislamiento termico de las

Through a comparison between the 1980s and 1990s, the article examines developments in the economic order and social structure of Brazil with particular emphasis on political and institutional changes. With this aim, the paper looks specifically at the style of public management, the nature of the decision-making process, and the channels of statesociety interaction as well as the mechanisms for access to the decision-making centres. Finally, the article assesses the changes and relative importance of strategic actors in the new capitalist order.El artículo evalúa el alcance y la profundidad de las transformaciones desencadenadas en Brasil a partir de la década de los años 80, cuando la instauración de la democracia y la ejecución de las reformas orientadas al mercado asumen el primer plano de la agenda pública. Mediante un contraste entre las décadas de los 80 y 90, este trabajo enfatiza los cambios en el orden económico y en la organización social del país, destancando las modificaciones de naturaleza política e institucional. Y para ello analiza particularmente el estilo de gestión pública, la naturaleza del proceso de toma de decisiones, las formas de articulación entre Estado y sociedad, así como los canales de acceso a los centros de decisión. Por último, se abordan las transformaciones en el peso relativo y en el papel de los actores estratégicos del nuevo orden capitalista en construcción.

    Full Text Available OBJECTIVES: To determine 1 the degree of soil contamination by parasites; 2 the prevalence of contaminated samples; 3 the overall number of parasitic forms, by distance between the collection site and the domicile; 4 the mean number of parasite forms per peri-household area; and 5 the variables associated with the total number of parasite forms. METHODS: Soil samples were collected in the peridomicile of 18 (out of a total sample of 63 and 22 (out of 190 residences of the Faxinal and Ivaí indigenous territories (ITs, respectively, from March 2005 through October 2006, and evaluated by the methods of Baermann, modified Faust et al., and Lutz. RESULTS: The overall prevalence of samples contaminated by enteroparasites of humans or of animals with zoonotic potential was 75.7% (84 out of 111 in Faxinal and 96.2% (127 out of 132 in Ivaí. The most prevalent parasites were Ascaris spp., Isospora spp., and Toxocara spp. Positive statistical associations were observed between the number of parasitic forms per domicile and the following variables: time of year (season, the presence of bathrooms in the domicile, and the presence of excrement on peridomiciliar soil. CONCLUSIONS: The high level of soil contamination in Faxinal and Ivaí 1 constitutes a potential source of parasitic infection and 2 suggests that the treatment of human and animal excreta continues to be inadequate.OBJETIVOS: Determinar: 1 el grado de contaminación parasitaria del suelo; 2 la prevalencia de muestras contaminadas; 3 el número general de formas parasitarias, en función de la distancia entre el sitio donde se tomaron las muestras y el domicilio; 4 el número promedio de formas parasitarias por área peridomiciliar y 5 las variables relacionadas con el número total de formas parasitarias.

    El McVCO es un generador de frecuencias basado en un microcontrolador que reemplaza al oscilador controlado por voltaje (VCO) utilizado en telemetría analógica de datos sísmicas. Acepta señales de baja potencia desde un sismómetro y produce una señal subportadora modulada en frecuencia adecuada para enlaces telefónicos o vía radio a un lugar remoto de recolección de datos. La frecuencia de la subportadora y la ganancia pueden ser seleccionadas mediante un interruptor. Tiene la opción de poder operar con dos canales para la observación con ganancia alta y baja. El McVCO fue diseñado con el propósito de mejorar la telemetría analógica de las señales dentro de la Pacific Northwest Seismograph Network (PNSN) (Red Sismográfica del Noroeste del Pacífico). Su desarrollo recibió el respaldo del Programa de Geofísica de la Universidad de Washington y del "Volcano Hazards and Earthquake Hazards programs of the United States Geological Survey (USGS) (Programa de Investigaciones de Riesgos Volcánicos y Programa de Investigaciones de Riesgos Sísmicos de los EEUU). Cientos de instrumentos se han construido e instalado. Además de utilizarlo el PNSN, el McVCO es usado por el Observatorio Vulcanológico de Alaska para monitorear los volcanes aleutianos y por el USGS Volcano Disaster Assistance Program (Programa de Ayuda en las Catástrofes Volcánicas del USGS) para responder a crisis volcánicas en otros países. Este manual cubre el funcionamiento del McVCO, es una referencia técnica para aquellos que necesitan saber con más detalle cómo funciona el McVCO, y cubre una serie de temas que requieren un trato explícito o que derivan del despliegue del instrumento.

    Full Text Available Este ensayo de investigación empírica analiza los determinantes del ingreso y del gasto en los hogares colombianos. Utilizando un modelo del ciclo de vida con datos de la encuesta de hogares de 1994 y 1995, muestra que el comportamiento del ingreso está afectado principalmente por las características demográficas del hogar y los rasgos socio ocupacionales de sus miembros. El comportamiento del gasto está determinado ante todo por el ingreso y, en menor medida, por las características sociales del hogar y el gasto de otros hogares con características similares. También examina la influencia de la incertidumbre acerca de los ingresos en el gasto de los hogares para comprobar si estos actúan con motivos de precaución.

Se presentan solo algunos datos y comentarios que encaucen o invoquen otras líneas que en materia de historia relacionada con la demografía se revelen. Este ensayo a modo de revisión bibliográfica es una ligera aproximación con apuntamientos, cuyo fin es encauzar o motivar algunas reflexiones que sean objeto de estudios más profundos y mejor documentados. Las interpretaciones históricas sobre las movilidades demográficas son materia de estudio de los especialistas en la Demografía Histórica. En consecuencia, el demógrafo histórico ideal no existe, pero con algunas habilidades tiene la esperanza de contribuir provechosamente en el campo de la demografía histórica. De ahí que todos los argumentos históricos tienen algo de imprecisión o falsedad, porque nadie puede estar totalmente seguro o inseguro de nada. Los grados de certeza son variables.

  9. Estudio del CH interestelar

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    Full Text Available Nos proponemos analizar un proceso de comunalización situado en parajes rurales de la cuenca del arroyo Comallo, provincia de Río Negro. En agosto de 2011 se conformó formalmente allí la comunidad mapuche Newen Ñuke Mapu que pasó a integrarse a las comunidades denominadas “nuevas” en la provincia, por contraste con aquellas consideradas “tradicionales”. Nuestro argumento es que esa novedad no es tal, sino que subyace un proceso de comunalización de larga duración que ha estado en permanente disputa con políticas estatales atomizadoras. En este sentido, se trata de un colectivo que se ha desarrollado a la sombra del estado argentino. Comenzaremos con un recorrido histórico en función de ubicar este caso en el proceso de incorporación del pueblo mapuche al estado nacional. A continuación analizamos el proceso de comunalización en tres escenarios históricos anclados en crisis de diferente tipo. 1 El presente que retoma la conformación de la comunidad mapuche.

    These pictures are divided into six chapters: Background, Components, Springline, Piers, Arch, Centring Erection and Removal, and Trimming.

    A lo largo de la historia, el Arco de fábrica ha sido el componente constructivo más característico de la Arquitectura y la Ingeniería desde que después de sus inicios etruscos en la época romana fuera desarrollado adelantándose con ello a la cultura helénica.
    El Arco, desde entonces, viene empleándose como una solución constructiva eficiente para cubrir espacios con materiales que no soportan tracciones. La originalidad técnica del Arco lo ha llevado a imponerse como símbolo de las hazañas bélicas como era el Arco de Triunfo.
    En el cambio de siglo y milenio en el que nos encontramos, un salto técnico fundamental se desvela en este Congreso, el Sistema de Albañilería Integral, que abre la posibilidad de ampliar el campo de aplicación de la albañilería con la incorporación del acero, a través de las perforaciones de las piezas, lográndose por fin armar en las tres direcciones del espacio cualquier muro de fábrica que se desee.
    El Arco del Milenio conmemoró el 12th IBMAC de Madrid, mostrando en él los avances técnicos que el Sistema de Albañilería Integral permite, al tratarse de un arco inclinado en el espacio y, por tanto, el primer arco de fábrica construido fuera de la vertical, mediante fábrica de Ladriflor aparejada a tizón, reforzada con barras y cercos.

    Full Text Available Las áreas de humedal ocupan casi el 5 % del territorio de la Patagonia argentina. En la zona extrandina y el desierto patagónico estos ecosistemas son esenciales para sostener numerosas especies de fauna y flora silvestre. Además, los humedales del norte patagónico permiten el desarrollo de comunidades acuáticas complejas y constituyen el hábitat crítico de grupos de organismos como los peces y los anfibios incluidos en listados de conservación prioritaria. Estos ecosistemas tienen un funcionamiento complejo que depende estrechamente de las fluctuaciones de las variables meteorológicas y son por lo tanto muy sensibles a los efectos del cambio climático. En la actualidad el uso de la tierra, la introducción de especies y la interacción de estos aspectos con el cambio climático constituyen las variables de mayor impacto sobre estos ambientes patagónicos. En este trabajo se presenta información geográfica, geomorfológica y climática de un número de humedales del norte de la Patagonia argentina. Por otra parte, se sintetiza información sobre la flora y la distribución de peces y anfibios con el propósito de enfatizar la importancia de estos ambientes en el mantenimiento de la biodiversidad regional. Por último, se señalan los procesos que actualmente afectan a estos sistemas poniendo en evidencia la necesidad de obtención de conocimientos básicos para el diseño de planes de manejo y conservación de sus comunidades biológicasAlmost 5 % of the lansdscape of Patagonia is occupied by wetlands. In the extra-andean region and the patagonian desert, wetlands are essential for sustaining biodiversity and wildlife. Besides, North patagonian wetlands present complex aquatic communities and provide habitat for threatened species of fishes and amphibians. These ecosystems have complex dynamics mostly driven by climatic fluctuations which make them vulnerable to the effect of climate change. Nowadays, the main impact on patagonian

Contrario a los supuestos de la literatura sobre la posmodernización de las campañas electorales, los resultados del estudio muestran que el uso político de las redes sociales en las elecciones locales en México es todavía limitado y que los canales basados en Internet aún no han logrado desplazar a las formas tradicionales de comunicación ni de participación electoral. En general, los datos revelan que las redes sociales se utilizan esencialmente como agenda o diario de actividades de los candidatos, los cuales buscan una mayor visibilidad de su imagen, pero con escasa incidencia en los resultados electorales. / The aim of this article is to examine political party communication through social media (Facebook and Twitter in the 2015 local congressional elections of the State of Mexico.

The main purpose of this work is to investigate (I if the differences in the degree of feminization of the migratory flows towards both countries are related to the job market demand and (II if this has had implications in the household structures of these migrants. The results suggest that the job market characteristics of the country of destiny might be behind the gender composition of the migratory flows to Spain and the US. In relation with the households, the female presence in complex households without a core is bigger in the collectives with more female presence. These differences are maintained when control variables are introduced, such as age, years of residence and the educational level of the migrants.Con datos censales de Estados Unidos de América y España, en este artículo se comparan las estructuras ocupacionales y de los hogares de la población dominicana y ecuatoriana en los dos países. La finalidad principal del trabajo es investigar (I si las diferencias en el grado de feminización de los flujos migratorios hacia ambos países responden a una cuestión de la demanda del mercado laboral y (II si ha tenido implicaciones en la estructura de los hogares de estos migrantes. Los resultados sugieren que las características del mercado laboral del país de destino podrían estar detrás de la composición de género de los flujos migratorios hacia España y Estados Unidos. En relación con los hogares, la presencia de las mujeres en hogares complejos y sin núcleo es mayor en aquellos colectivos más feminizados. Estas diferencias se mantienen cuando se introducen variables de control como la edad, los años de residencia y el nivel educativo de los/las inmigrantes.

    Full Text Available Colombia, al igual que la mayoría de países latinoamericanos, consciente de las repercusiones sociales y económicas negativas del trabajo infantil, se ha comprometido en la lucha por la erradicación de este fenómeno. Prueba de ello es la ratificación por parte del gobierno colombiano en el año 2007, del Convenio 182 de la OIT sobre la Prohibición de las Peores Formas de Trabajo Infantil y la Acción Inmediata para su Eliminación. En el plano regional, como parte del Plan de Desarrollo del Departamento del Valle del Cauca 2008-2011, se está implementando actualmente una estrategia territorial de erradicación del trabajo infantil en sus 42 municipios. Considerando este panorama, este trabajo indaga cuáles son los determinantes del trabajo infantil y la escolaridad en el departamento del Valle a partir de los datos de la Encuesta Nacional de Calidad de Vida del año 2003. Para el análisis se emplea un modelo econométrico Probit Bivariado, que permite el estudio conjunto e interrelacionado de decisiones diferentes, en este caso la asistencia escolar y el trabajo.

    Full Text Available La infección del tracto urinario (ITU, con sus múltiples presentaciones clínicas, está entre las enfermedades infecciosas más frecuentes, tanto en pacientes ambulatorios como hospitalizados. El uso del examen de orina completa y de urocultivo debe ser racional. La bacteriuria asintomática no debe ser buscada ni tratada, en parte porque esto favorece el desarrollo de bacterias resistentes a antibióticos. Distintos cuadros clínicos requieren de distintas duraciones de terapia antibiótica, y tanto el exceso de días de tratamiento como su falta deben evitarse. Se requiere investigación en la búsqueda de estrategias más efectivas para prevenir las ITU recurrentes y en el desarrollo de nuevos antibióticos orales para las ITU resistentes.

    Full Text Available INTRODUCCIÓN: Los Desórdenes por Deficiencia de Yodo son un problema serio de salud pública, con cerca de 2 mil millones de personas a riesgo de padecerlos, pudiendo causar bocio neonatal, cretinismo, retardo mental, hipotiroidismo, entre otros. Estos desórdenes son aún prevalentes, y en algunos casos los esfuerzos para su erradicación se han traducido en aumento del riesgo de exceso poblacional de yodo y autoinmunidad tiroidea. En Colombia, se desconoce el estado real de yodo en la población. OBJETIVOS: Determinar la mediana de la yoduría en población escolar, y de los hábitos del consumo de sal, función y parámetros de autoinmunidad tiroidea, y cociente intelectual. MATERIALES Y MÉTODOS: Estudio basado en la comunidad, de corte transversal. Se evaluaron las variables sociodemográficas, la frecuencia de bocio y los niveles de TSH, anti-TPO, anti-Tg, anti-TSHR, yoduria, test de factor G de Cattell, y hábitos del consumo de sal. RESULTADOS: El consumo de sal promedio persona/día fue de 18,13 g. El 37,9% presentó bocio. 36,1% tenían un valor límite en el cociente intelectual. La mediana de yoduria fue de 510,3 μg/L. El 42,75% tuvo anti-TPO positivos, y el 2,87% anti-Tg positivos. El 10% presentó niveles de TSH elevados. CONCLUSIÓN: En escolares de zona urbana, hay un exceso en la mediana de yoduria, pudiendo explicarse por el alto consumo de sal. La alta prevalencia de autoinmunidad tiroidea y bocio, junto al alto nivel de la TSH, puede ser consecuencia del exceso en la ingesta de sal y de otros factores medioambientales/ hereditarios.

(1997 from the University of Tilburg have analyzed motives, tendencies and frequency of crying, emotions and feelings that provoke crying, as well as differences and similarities among countries and sexes. Results show that women have a tendency to cry more frequently and intensively than men. It has also been noted that, in certain countries, there is a link between crying in women and their monthly period.

    Full Text Available La inestabilidad compleja del codo es de reciente descripción y controversial en sus resultados; es el estado que se deriva del daño estructural y funcional, producido por la incongruencia de las superficies articulares y las estructuras ligamentosas que estabilizan el codo. Se realizó un estudio descriptivo prospectivo, en el período comprendido entre enero de 2011 y abril de 2013, en una muestra no probabilística de ocho pacientes (diez codos, seleccionados según criterios de inclusión y exclusión. Los objetivos fundamentales del estudio fueron: la actualización de conocimientos para el manejo de la enfermedad y la caracterización de los resultados obtenidos en los afectados por esta dolencia que fueron operados en el Hospital Dr. Ernesto Guevara de la Serna de la provincia de Las Tunas. Se analizaron los datos mediante técnicas estadísticas descriptivas y se realizó la evaluación clínica y radiográfica de los lesionados. El tratamiento se ejecutó según los hallazgos y consistió en: reparación ligamentosa, actuación sobre las partes óseas dañadas y colocación de osteosíntesis diversas. La edad promedio fue de 39,2 años y predominó el sexo masculino. A todos se les practicó reparación ligamentosa, siete cupulectomías y seis aplicaciones de cerclajes anti-distractores. Existieron dos reluxaciones y una sepsis local. La amplitud de movimientos fue aceptable dentro del rango compatible, con una buena función ergonómica; de acuerdo a las comparaciones bibliográficas actualizadas que se realizaron. La fijación y reparación de los estabilizadores del codo brindan buenos resultados funcionales. La sistematización en el manejo de la enfermedad, la detección de complicaciones y el arsenal terapéutico disponible son factores a tener en cuenta

    Full Text Available In this article, the evolution of the different systems of transporting and storing submarine oil and its by-products (petroleum gas and natural gas, is dealt with stressing the importance of the use of concrete boats. Due to the high cost of oil pipelines, we have passed from tanks built on land to prestressed concrete tanks which can be berthed at great depths or anchored to the bottom to keep them afloat, it being possible to unmoor them for transferring them. Transporting and storing liquated gas leads US to see the advantages of prestressed concrete over steel, as the latter becomes brittle at low temperatures, whereas the former's strength increases. The different forms and possible sections are analyzed, stressing the great importance of the solution of the double concrete hull with pearlite insulation. Finally, a study is made of «light concretes », not the classical types used as thermal and acoustic insulation, but the semi-heavy ones made with expanded clay, high quality sand and P-450 cement, which technique is not yet as developed in Spain at might be wished.En este artículo se trata la evolución de los distintos sistemas de transporte y almacenamiento del petróleo submarino y sus derivados (gas de petróleo y gas natural, resaltando la importancia del uso de barcos de hormigón. Debido al gran coste de los oleoductos, se ha pasado de los tanques construidos en tierra firme a los depósitos de hormigón pretensado que pueden estar fondeados a gran profundidad o anclados al fondo para mantenerlos flotantes, existiendo la posibilidad de poder desamarrarlos para su traslado. El transporte y almacenamiento del gas licuado nos hace ver las ventajas del hormigón pretensado sobre el acero, pues éste se vuelve quebradizo a bajas temperaturas, mientras aquél aumenta su resistencia. Se analizan las diferentes formas y secciones posibles, destacando la gran importancia de la solución del doble casco de hormigón con

    Según el diccionario de la Real Academia Española (11, divertículo, del latín, diverticulum, quiere decir desviación de un camino; y desde el punto de vista anatómico, apéndice hueco y terminado en fondo de saco. (Gráfica No. 1.

    Goligher (17 lo define como la “posada al borde del camino, probablemente un lugar, a menudo, de mala reputación”.

    Según Hackford (18, el proceso fué descrito brevemente por Littre a comienzos del siglo XVIII; pero se le atribuye a Cruveilhier la primera descripción como proceso patológico en 1849, quien, además, mencionó: “encontramos, no rara vez, en el sigmoide, entre las bandas de fibras musculares longitudinales, una serie de pequeños tumores piriformes oscuros, que están formados por hernias de la mucosa a través de brechas en la capa muscular” (17.

    Fleischman en 1815 hizo la primera observación de la enfermedad y empleó el término divertículo (45.

    Full Text Available Las causas de ataque isquémico en pacientes jóvenes, son difíciles de encontrar pese a las investigaciones sistemáticas dirigidas a descartar origen cardiaco, alteraciones de la coagulación o cualquier otro tipo de enfermedades vasculares; de ahí la definición de «criptogénico». Se especula acerca del papel potencial de los cortocircuitos intracardiacos de derecha a izquierda como vía de embolismos paradójicos que culminan en enfermedad cerebral isquémica. Se demostró que la ecocardiografía transesofágica con inyección venosa periférica de solución salina agitada, es el método de elección para diagnosticar foramen ovale permeable y cortocircuito de derecha a izquierda. Estudios prospectivos que utilizan tratamiento con ácido acetil salicílico o warfarina, no demuestran una reducción significativa de los ataques recurrentes. Aunque, tanto el cierre quirúrgico del foramen ovale permeable como el percutáneo, muestran una disminución de la tasa de eventos embólicos subsecuentes, aún se discute su indicación, al menos hasta que aparezcan resultados de trabajos con escogencia al azar, que están en proceso en la actualidad. Sin embargo, los casos de embolismo paradójico recurrente y en los buzos profesionales, ambos casos con aneurisma del septum auricular y foramen ovale permeable asociados, son las únicas indicaciones inequívocas de cierre percutáneo. El cierre exitoso, definido por ecocardiografía transesofágica, parece predecir la ausencia de eventos embólicos recurrentes. En la medida en que la tasa de complicaciones de la implantación de dispositivos disminuya y que éstos sean técnicamente más sencillos, el cierre percutáneo se impondrá al quirúrgico.The causes of ischemic stroke in young patients are difficult to find, in spite of systematic investigations directed to rule out heart etiology, alterations in coagulation or any other type of vascular disease; hence the «cryptogenic» definition.

    Full Text Available Durante los últimos 10 años, los puentes extradosados se han convertido en una solución estructural atractiva alrededor del mundo, gracias a los buenos resultados obtenidos con las primeras realizaciones en Japón. Esta nueva tipología, reconocida generalmente como una solución intermedia entre los puentes atirantados y los de pretensado de viga cajón construidos por voladizos sucesivos, se ha convertido en una opción interesante. Por consiguiente, dado el interés que hoy en día existe alrededor de este tipo de puente, en este trabajo se presenta el contexto histórico que describe su origen, y se exponen la influencia de los principales elementos estructurales en el comportamiento del puente, y los criterios de diseño que han sido propuestos por investigadores en el tema. De esta manera, se espera ofrecer una visión general de la concepción y el comportamiento estructural de los puentes extradosados para que sea considerada una alternativa más de tipología estructural de puentes en nuestro medio.Over the past 10 years, Extradosed bridges have become an attractive structural type around the world, due to the good results obtained with the first bridges constructed in Japan. This new typology, generally recognized as an intermediate solution between cable stayed bridges and cantilever constructed prestressed box-girder bridges, because these take advantages of design and constructions methods of the other two typologies, has become an interesting option. Therefore, given the interest that exist about this type of bridge, in this paper the historical context that describes its origin, the influence of the principal structural elements and the design criteria proposed by researchers are presented. In this way it is expected to offer a general insight into the design conception and structural behavior of Extradosed Bridges, so that they may be considered as an alternative structure for bridges in the Americas.

    Full Text Available RESUMEN: La propuesta que presento tiene un gran objetivo general: estudiar y evaluar una pedagogía del poder —o múltiples—, unas técnicas del poder, unas prácticas. Para ello, propongo al lector poner a funcionar un grupo de presupuestos teóricos y metodológicos, provinientes del campo de la historia para ser aplicados también en el espacio de la historia de la educación en un estudio de caso concreto, Castilla en la época del emperador Carlos I, en función del análisis de dos grandes macrorrealidades que aún hoy perviven: la estructura del Estado y el espacio creado en sus relaciones con la universidad. Para la época seleccionada (la primera mitad del siglo XVI, estaríamos en presencia de un Estado monárquico con un poder «casi» incuestionable, y una universidad como la de Salamanca, referente indiscutible de la república de las letras del momento, tanto si la observamos en la península Ibérica como fuera de ella. Estas relaciones, estudiadas por ejemplo desde la historia de las familias de poder, o desde la microhistoria, pueden darnos como resultados nuevas perspectivas que nos encaminen hacia una nueva historia de la educación, hacia una historia cultural de la universidad y hacia una reflexión sobre un concepto interesante como el de pedagogía del poder. ABSTRACT: The proposal made in this paper has a great goal: to study and evaluate a pedagogy of power —or many—, it's techniques and it's practices. In order to achive this goal it makes the following proposal for the reader: putting to work a set of theorycal and metodological proposals taken from the field of history in order to apply them in a concrete case: the Castilla at the times of emperor Carlos I. This study will be made trough the analysis of two macrorealites still present in our times: the structure of the State and the space created trough it's relationship with the university. This set us in the first half of the XVI century with a monarchic
