Impact of etanercept-methotrexate therapy on patient-reported outcomes in rheumatoid arthritis patients with up to 12 months of symptoms.

Background/Purpose: Patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) are critical in evaluating RA treatment effects on function and health-related quality of life (HR-QoL). Significant improvement in PROs has been reported in RA studies of biologic agents, including etanercept (ETN), but most studies have been conducted in patients with established disease. In addition to assessing treatment effects in early RA, there is interest in therapeutic strategies that allow dose reduction or withdrawal of biologic therapy (biologic-free) after induction of response. The PRIZE trial is an ongoing, 3-period study to evaluate the efficacy of combined ETN and methotrexate (MTX) therapy in patients with early, moderate-to-severe RA and to assess whether efficacy (remission) can be maintained with ETN dose reduction or biologic-free (Period 2) or drug-free (Period 3). Herein we report PROs associated with ETN 50 mg QW plus MTX (ETN50/MTX) therapy administered for 52 wks in Period 1 (induction) of the PRIZE trial. Methods: In Period 1, MTX- and biologic-naı‥ve patients with early, active RA (symptom onset 12 mo from enrollment; DAS28 _3.2) received open-label ETN50/MTX for 52 wks. The starting dose of MTX was 10 mg QW; at the discretion of the investigator, titration was permitted up to a maximum of 25 mg QW to achieve remission. Corticosteroid boosts were administered to patients not achieving low disease state at wks 13 and 26, unless contraindicated or not tolerated. PROs were assessed using the Health Assessment Questionnaire (HAQ) total score; Patient Acceptable Symptom State (PASS); EuroQol-5 Dimensions (EQ-5D) total index; Short Form Health Survey (SF-36); Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue; Work Instability Scale for Rheumatoid Arthritis (RAWIS); and Work Productivity and Activity Impairment Questionnaire: Rheumatoid Arthritis (WPAI:RA). Results: A total of 306 patients received treatment in Period 1 (mITT population); 222 (73%) patients completed the period. The majority of patients were female (70%), with a mean age of 50 y, mean DAS28 of 6.0 (median, 6.0), and duration of disease symptoms from onset of 6.5 months (median, 6.3 mo). Significant and clinically meaningful improvements in PROs, including in HAQ, EQ-5D, SF-36, and FACIT-Fatigue, were demonstrated with ETN50/MTX therapy from baseline to the final on therapy visit (Table; P_0.0001). Similar improvements were observed in all dimensions of RA-WIS and WPAI:RA (Table; P_0.0001). Conclusion: Combination therapy with ETN50/MTX for 52 wks in patients with _12 mo of symptomatic, active RA resulted in significant, clinically important improvements in measures of physical function, including normal HAQ (66.6% of patients), HR-QoL, fatigue, and work productivity. These outcomes are consistent with those reported in prior studies in patients with more established disease.

Association between nonmedical prescription drug use and health status among young swiss men.

PURPOSE: To examine the relationship between the nonmedical prescription drug use (NMPDU) of six drug classes and health. METHODS: Data on young adults males (mean age, 19.96 years) from the baseline and follow-up of the Cohort Study on Substance Use Risk Factors (C-SURF) were used (n = 4,958). Two sets of logistic regression models were fitted to examine the associations between NMPDU of opioid analgesics, sedatives or sleeping pills, anxiolytics, antidepressants, beta blockers and stimulants, and health status (assessed using the Medical Outcomes Study 12-Item Short Form Survey Instrument [SF-12 v2]). We first computed odds ratios between NMPDU at baseline and poor mental and physical health at follow-up, adjusting for poor mental or physical health at baseline. We then computed odds ratios between poor mental and physical health at baseline and NMPDU at follow-up, adjusting for NMPDU at baseline. RESULTS: Three key findings regarding mental health were (1) there was a reciprocal risk between poor mental health and sedatives and anxiolytics; (2) poor mental health increased NMPDU of opioid analgesics and antidepressants but not vice versa; and (3) there were no associations with stimulants. Three key findings regarding physical health were (1) poor physical health increased the risk of NMPDU of anxiolytics; (2) the only reciprocal risk was between physical health and NMPDU of opioid analgesics; and (3) there were no associations with stimulants. CONCLUSION: These results, among the first ever on reciprocal effects between NMPDU and mental and physical health status, give unique information concerning the adverse effects of NMPDU on health and vice versa. The study shows that NMPDU is not only a sign of self-medication but may induce health problems.

Psychometric properties of the Marlowe-Crowne Social Desirability Scale in eight African countries and Switzerland

The purpose of this study was to assess the cross-cultural validity of the Marlowe-Crowne Social Desirability scale short form C, in a large sample of French-speaking participants from eight African countries and Switzerland. Exploratory and confirmatory analyses suggested retaining a two-factor structure. Item bias detection according to country was conducted for all 13 items and effect was calculated with R2. For the two-factor solution, 9 items were associated with a negligible effect size, 3 items with a moderate one, and 1 item with a large one. A series of analyses of covariance considering the acquiescence variable as a covariate showed that the acquiescence tendency does not contribute to the bias at item level. This research indicates that the psychometric properties of this instrument do not reach a scalar equivalence but that a culturally reliable measurement of social desirability could be developed.

Cannabis Use in Patients with Fibromyalgia: Effect on Symptoms Relief and Health-Related Quality of Life

Background: The aim of this study was to describe the patterns of cannabis use and the associated benefits reported by patients with fibromyalgia (FM) who were consumers of this drug. In addition, the quality of life of FM patients who consumed cannabis was compared with FM subjects who were not cannabis users. Methods: Information on medicinal cannabis use was recorded on a specific questionnaire as well as perceived benefits of cannabis on a range of symptoms using standard 100-mm visual analogue scales (VAS). Cannabis users and non-users completed the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI) and the Short Form 36 Health Survey (SF-36). Results: Twenty-eight FM patients who were cannabis users and 28 non-users were included in the study. Demographics and clinical variables were similar in both groups. Cannabis users referred different duration of drug consumption; the route of administration was smoking (54%), oral (46%) and combined (43%). The amount and frequency of cannabis use were also different among patients. After 2 hours of cannabis use, VAS scores showed a statistically significant (p<0.001) reduction of pain and stiffness, enhancement of relaxation, and an increase in somnolence and feeling of well being. The mental health component summary score of the SF-36 was significantly higher (p<0.05) in cannabis users than in non-users. No significant differences were found in the other SF-36 domains, in the FIQ and the PSQI. Conclusions: The use of cannabis was associated with beneficial effects on some FM symptoms. Further studies on the usefulness of cannabinoids in FM patients as well as cannabinoid system involvement in the pathophysiology of this condition are warranted

Involuntary treatment of alcohol-dependent patients: a study of 17 consecutive cases of civil commitment.

AIM: To investigate the baseline and follow-up characteristics of a group of alcohol-dependent patients being treated under civil commitment. METHODS: This study involved a cross-sectional comparative analysis of baseline characteristics and a follow-up survey of a group of committed alcoholic patients. The study was undertaken in the Alcohol Unit of a 1,000-bed general and university hospital. The study included 17 consecutive cases of civil commitment (representing 15 patients, of whom 2 were committed twice) and a comparative group of 34 randomly selected age- and sex-matched patients. Baseline characteristics of the cases (at the time of commitment) and of patients from the comparative group were collected from medical records, including sociodemographic data, medical condition, patterns of drinking and number and dates of previous treatments for alcohol-related problems. A structured follow-up interview of the cases provided information on their medical condition, social status, patterns of alcohol use, type and duration of residential treatment as well as their perceptions of commitment. RESULTS: During a 4-year period, our Unit referred 23 cases of alcohol-dependent patients (out of 367) to the Guardianship Authority, requesting civil commitment. On 17 occasions, patients were committed to residential treatment, including 2 patients who underwent commitment on two separate occasions, thus representing a total of 15 different patients. In comparison with age- and sex-matched patients seen at the Unit, the cases were characterized by multiple medical, social and psychological alcohol-related impairments. At the time of follow-up, 14 out of 15 patients were alive, among whom 10 agreed to be interviewed. Eight of these reported complete abstinence, whereas 9 considered their alcohol problem as less severe than before. The average duration of commitment was 29 weeks. The majority of patients retrospectively considered the measure as having been justified and useful. The patients' satisfaction with the decision to commit was higher among women than among men. Health-related quality of life at the time of follow-up, as assessed by the MOS 36-Item Short Form Health Survey questionnaire, was good on average and better than that usually reported by other cohorts of alcoholics undergoing treatment. CONCLUSIONS: The usefulness of residential civil commitment of certain severely impaired alcohol-dependent patients is underscored. This study suggests that civil commitment not only may save the lives of endangered patients but could also be a health-promoting measure that may sometimes allow for recovery from dependence. Unexpectedly, this measure was retrospectively well accepted by many patients, who considered the commitment decision as having been justified and useful.

Health-related quality of life in patients with dual diagnosis: clinical correlates

Background: Although the studies published so far have found an affectation in the Health Related Quality of Life (HRQOL) in both psychiatric and substance use dependence disorders, very few studies have applied HRQOL as an assessment measure in patients suffering both comorbid conditions, or Dual Diagnosis. The aim of the current study was to assess HRQOL in a group of patients with Dual Diagnosis compared to two other non-comorbid groups and to determine what clinical factors are related to HRQOL. Methods: Cross-sectional assessment of three experimental groups was made through the Short Form 36 Item Health Survey (SF-36). The sample consisted of a group with Dual Diagnosis (DD; N=35), one with Severe Mental Illness alone (SMI; N=35) and another one with Substance Use Dependence alone (SUD; N=35). The sample was composed only by males. To assess the clinical correlates of SF-36 HRQOL, lineal regression analyses were carried out. Results: The DD group showed lower scores in most of the subscales, and in the mental health domain. The group with SUD showed in general a better state in the HRQOL while the group with SMI held an intermediate position with respect to the other two groups. Daily medication, suicidal attempts and daily number of coffees were significantly associated to HRQOL, especially in the DD group. Conclusions: The DD group showed lower self-reported mental health quality of life. Assessment of HRQOL in dual patients allows to identify specific needs in this population, and may help to establish therapeutic goals to improve interventions.

CoDiab-VD: protocol of a prospective population-based cohort study on diabetes care in Switzerland.

BACKGROUND: Diabetes represents an increasing health burden worldwide. In 2010, the Public Health Department of the canton of Vaud (Switzerland) launched a regional diabetes programme entitled "Programme cantonal Diabète" (PcD), with the objectives to both decrease the incidence of diabetes and improve care for patients with diabetes. The cohort entitled CoDiab-VD emerged from that programme. It specifically aimed at following quality of diabetes care over time, at evaluating the coverage of the PcD within this canton and at assessing the impact of the PcD on care of patients with diabetes. METHODS/DESIGN: The cohort CoDiab-VD is a prospective population-based cohort study. Patients with diabetes were recruited in two waves (autumn 2011--summer 2012) through community pharmacies. Eligible participants were non-institutionalised adult patients (≥ 18 years) with diabetes diagnosed for at least one year, residing in the canton of Vaud and coming to a participating pharmacy with a diabetes-related prescription. Women with gestational diabetes, people with obvious cognitive impairment or insufficient command of French were not eligible. Self-reported data collected, included the following primary outcomes: processes-of-care indicators (annual checks) and outcomes of care such as HbA1C, (health-related) quality of life measures (Short Form-12 Health Survey--SF-12, Audit of Diabetes-Dependent Quality of Life 19--ADDQoL) and Patient Assessment of Chronic Illness Care (PACIC). Data on diabetes, health status, healthcare utilisation, health behaviour, self-management activities and support, knowledge of, or participation to, campaigns/activities proposed by the PcD, and socio-demographics were also obtained. For consenting participants, physicians provided few additional pieces of information about processes and laboratory results. Participants will be followed once a year, via a mailed self-report questionnaire. The core of the follow-up questionnaires will be similar to the baseline one, with the addition of thematic modules adapting to the development of the PcD. Physicians will be contacted every 2 years. DISCUSSION: CoDiab-VD will allow obtaining a broad picture of the care of patients with diabetes, as well as their needs regarding their chronic condition. The data will be used to evaluate the PcD and help prioritise targeted actions. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, identifier NCT01902043, July 9, 2013.

Efficacy of brief interdisciplinary psychotherapeutic intervention for motor conversion disorder and nonepileptic attacks.

OBJECTIVE: The objective was to compare a brief interdisciplinary psychotherapeutic intervention to standard care as treatments for patients recently diagnosed with severe motor conversion disorder or nonepileptic attacks. METHODS: This randomized controlled trial of 23 consecutive patients compared (a) an interdisciplinary psychotherapeutic intervention group receiving four to six sessions by a consultation liaison psychiatrist, the first and last sessions adding a neurological consultation and a joint psychiatric and neurological consultation, and (b) a standard care group. After intervention, patients were assessed at 2, 6 and 12 months with the Somatoform Dissociation Questionnaire (SDQ-20), Clinical Global Impression scale, Rankin scale, use of medical care, global mental health [Montgomery and Asberg Depression Rating Scale, Beck Depression Inventory, mental health component of Short Form (SF)-36] and quality of life (SF-36). We calculated linear mixed models. RESULTS: Our intervention brought a statistically significant improvement of physical symptoms [as measured by the SDQ-20 (P<.02) and the Clinical Global Impression scale (P=.02)] and psychological symptoms [better scores on the mental health component of the SF-36 (P<.05) and on the Beck Depression Inventory (P<.05)] and a reduction in new hospital stays after intervention (P<.05). CONCLUSION: A brief psychotherapeutic intervention taking advantage of a close collaboration with neurology consultants in the setting of consultation liaison psychiatry appears effective.

L'insatisfaction des besoins en soins de support chez les patients atteints d'un cancer du poumon en fonction du genre, de l'âge et du tabagisme : étude descriptive corrélationnelle transversale

Les patients atteints d'un cancer du poumon souffrent de différents troubles physiques et psychosociaux sévères causés par la maladie et son traitement. Ces troubles engendrent plusieurs besoins en soins de support chez les patients. Afin de satisfaire leurs besoins et de leur offrir la meilleure qualité de soins possible, l'identification des besoins en soins de support des patients devient primordiale. But : Le but de l'étude est, dans un premier temps, d'identifier et de décrire les besoins insatisfaits en soins de support pour les patients souffrant d'un cancer du poumon pendant la phase de chimiothérapie dans un Centre Hospitalier Universitaire en Suisse (CHU). Dans un second temps, le but de l'étude est également d'explorer l'éventuelle existence de différences quant au degré d'insatisfaction, tel qu'exprimé par les patients, notamment en fonction de l'âge, du genre et du tabagisme des patients. Cadre théorique : La présente étude se base sur la théorie du déficit d'auto-soin de Dorothea Orem. Méthode : Le travail de recherche s'est basé sur un devis descriptif corrélationnel transversal. L'échantillon, composé de 26 patients atteints d'un cancer du poumon, a été recruté selon la méthode non probabiliste accidentelle dans le service d'oncologie ambulatoire du CHU. Le recueil des données a été effectué à travers deux questionnaires auto-administrés aux patients (Supportive Care Needs Survey Short Form 34 et un questionnaire socio-démographique). Les données médicales ont été recueillies par l'étudiant chercheur à travers la consultation des dossiers médicaux. Résultats : Les résultats montrent que les besoins les plus insatisfaits chez les patients se regroupent surtout autour des besoins liés aux aspects psychologiques et physiques/vie quotidienne. Les patients expriment aussi un degré d'insatisfaction par rapport aux besoins en information ainsi qu'aux soins et au soutien prodigués par les soignants. Les deux besoins le plus fréquemment (65,38 %) exprimés comme insatisfaits par les patients ont été : « être informé de ce que vous pouvez faire vous-même pour aller mieux » et « l'incertitude face à l'avenir ». Les différences des degrés d'insatisfaction, tel qu'exprimés par les patients, en fonction de l'âge, du genre du tabagisme ont permis de poser des hypothèses quant aux relations entre ces variables et le degré d'insatisfaction : les femmes seraient plus insatisfaites de toutes les dimensions liées aux besoins en soins de support ; les patients d'âge égal ou supérieur à 65 ans seraient plus insatisfaits quant aux besoins physiques/vie quotidienne, psychologiques et de soutien; les patients d'âge inférieur à 65 ans seraient plus insatisfaits quant aux besoins liés à la sexualité; les non-fumeurs avant le diagnostic seraient plus insatisfaits quant aux besoins physiques/vie quotidienne, d'information et sexuels ; les patients qui arrêtent de fumer après le diagnostic seraient plus insatisfaits quant aux besoins physique/vie quotidienne, psychologique et de soutien. Conclusion : Cette étude met en évidence le fait que, pendant la phase de chimiothérapie, les patients atteints d'un cancer du poumon expriment de l'insatisfaction par rapport à plusieurs besoins en soins de support. Afin d'améliorer la qualité des soins et de mieux répondre aux besoins des patients, les infirmières et les équipes interdisciplinaires présentes au sein des services d'oncologie du CHU sont appelés à prendre en considération l'insatisfaction exprimée par les patients.

Les besoins en soins de support chez les patients en phase d'un traitement ambulatoire, suivant l'annonce d'un diagnostic de cancer : étude descriptive transversale

Problématique L'incidence du cancer ne cesse d'augmenter dans les pays occidentaux et en Suisse, en constituant la deuxième cause de mortalité après les maladies cardiovasculaires. Si d'une part, les différents traitements oncologiques ont le potentiel de guérir certains cancers et d'augmenter l'espérance de vie des personnes concernées, ils sont associés à de multiples problèmes physiques et psychosociaux. De même, l'annonce de la maladie provoque une fragilité émotionnelle et sociale et la phase de traitement qui suit le diagnostic de cancer est souvent associé à des besoins psychologiques et d'information élevés. But Cette étude vise à décrire les besoins en soins de support insatisfaits chez les patients nouvellement diagnostiqués d'un cancer, au cours d'un traitement ambulatoire dans un Hôpital Cantonal de la Suisse. Elle vise également à identifier les associations entre les besoins en soins de support insatisfaits et les caractéristiques sociodémographiques et médicales. Méthode Cette étude corrélationnelle descriptive a été conduite auprès de 67 patients nouvellement atteints d'un cancer primaire ou d'une récidive, recrutés selon un échantillonnage non probabiliste par convenance consécutive. Le questionnaire auto-administré comprenait le Supportive Care Needs Survey Short Form 34 et un questionnaire sur des données sociodémographiques. Les données médicales ont été collectées par les chercheurs à travers les dossiers médicaux. Résultats Les trois besoins exprimés comme les plus insatisfaits étaient « la peur que le cancer se propage » (48,5%), « l'incertitude face à l'avenir » (45,4%) et « vos préoccupations face à l'incertitude de vos proches » (43,9%). Nous constatons une insatisfaction plus élevée des besoins psychologiques (M: 32,6 ; ET: 20,4) et des besoins d'information (M: 29,3 ; ET: 17,5) par rapport aux autres dimensions de besoins. À propos des caractéristiques associées a un plus haut niveau de besoins insatisfaits, nous trouvons qu'être plus jeune (29-56 ans) ou âgés de > 72 ans est positivement associé aux besoins insatisfaits du domaine psychologique (F = 3,50 ; p = 0,02) et de l'information/système de santé (F = 3,48 ; p = 0,02). Le jeune âge est aussi associé à plus de besoins dans le domaine sexuel (F = 2,85 ; p = 0,04). Il semble exister une association négative entre le niveau d'instruction et le degré d'insatisfaction des besoins psychologiques (F = 2,92, p = 0,06). Être retraité coïncide avec un plus grand degré d'insatisfaction dans les besoins physiques et des activités de la vie quotidienne (F = 4,64 ; p = 0,013). Finalement, avoir un moins bon état général est relié à plus de besoins physiques et de besoins issus du domaine des activités de la vie quotidienne (t = -2,85 ; p = 0,005). Conclusions Les présents résultats concordent avec les études antérieures. Cette étude a la particularité d'avoir identifié les besoins insatisfaits durant la phase de traitement qui suit l'annonce du diagnostic, sans se restreindre à une maladie cancéreuse spécifique, ce qui a été peu effectué auparavant. Les chercheurs infirmiers devraient poursuivre, en collaboration avec d'autres professionnels de la santé, les recherches visant le développement d'approches efficaces pour réduire les besoins insatisfaits chez des personnes atteintes de maladies cancéreuses.

The factorial structure of the 41-item version of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a Spanish population of 8 to 12 years-old

On this instrumental study we intend to analyse the factorial structure of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a Spanish sample using exploratory and confirmatory factorial analysis. As a second objective we intend to develop a short form of it for rapid screening and, finally, to analyze the reliabilities of both questionnaires. The SCARED was administered to a community sample of 1,508 children aged between 8 and 12 years. The sample was randomly split using half for the exploratory analysis and the other half for the confirmatory study. Furthermore a reduced version of the SCARED was developed using the SchmidLeiman procedure. Exploratory Factor Analysis yielded a four factor structure comprised of Somatic/panic, Generalized anxiety, Separation anxiety and Social phobia factors This structure was confirmed using Confirmatory Factor Analysis. The four factors, the full scale and the short scale showed good reliabilities. The results obtained seem to indicate that the Spanish version of the SCARED has good internal consistency, and along with other recent results, has a structure of four related factors that replicates the dimensions proposed for anxiety disorders by the DSM-IV-TR

Bound state solutions of schrödinger equation for a more general exponential screened coulomb potential via Nikiforov-Uvarov method

The arbitrary angular momentum solutions of the Schrödinger equation for a diatomic molecule with the general exponential screened coulomb potential of the form V(r) = (- a / r){1+ (1+ b )e-2b } has been presented. The energy eigenvalues and the corresponding eigenfunctions are calculated analytically by the use of Nikiforov-Uvarov (NU) method which is related to the solutions in terms of Jacobi polynomials. The bounded state eigenvalues are calculated numerically for the 1s state of N2 CO and NO

Improving Quality of Life of Patients With Schizophrenia In Acute Psychiatric Wards

The overall goal of this study was to identify means by which the quality of life (QoL) of patients with schizophrenia could be improved in acute psychiatric wards. First, subjective QoL of patients (n=35) was explored. Second, two different QoL instruments (EuroQoL-5D, EQ-5D; Quality of Life Enjoyment and Satisfaction Questionnaire Short Form, Q-LES-Q SF) were examined. Third, patients’ (n=35) and nurses’ (n=29) perceptions of nursing interventions to support patients’ QoL were examined. Fourth, the effect of three different patient education methods on patients’ QoL (n=311) was compared. The data were collected during the period 2005-2007. Patients named health, family, leisure activities, work or study, and social relationships most frequently as their important QoL areas. It emerged that patients’ QoL was impaired. Examination of two QoL instruments showed that the EQ-5D has moderate and the Q-LES-Q SF good internal consistency. Moreover, both instruments proved to be reasonably valid and feasible for use with patients with schizophrenia. Altogether six nursing interventions which nurses use to support patients’ QoL, and which should be further developed were identified from nurses’ descriptions: interventions related to care planning, empowering interventions, social interventions, activating interventions, security interventions, and interventions to support physical health. Evaluation of different patient education methods showed that patients’ QoL improved significantly during follow-up. No significant differences between groups were found. In light of the findings it is recommended to assess QoL of patients with schizophrenia as a basis for care planning and care evaluation in clinical settings. Valid and feasible instruments should be used in this assessment. Moreover, it is recommend that nursing interventions should be further developed to better improve patients’ QoL.

Qualidade de vida de graduandos da área da saúde

Esta investigação tem o objetivo de avaliar e comparar a qualidade de vida (QV) de graduandos da área da saúde de uma universidade pública. O estudo exploratório transversal incluiu voluntariamente 630 alunos dos cursos de enfermagem, farmácia, fonoaudiologia e medicina dessa instituição, correspondendo a 57% dessa população. Utilizou-se o Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) para avaliação da qualidade de vida, além de uma questão aberta relacionada à percepção do aluno sobre a influência da Universidade em sua qualidade de vida. O domínio com melhor escore foi a capacidade funcional, e o pior foi vitalidade. Na comparação da qualidade de vida entre as séries, o curso de farmácia apresentou piores escores nos anos iniciais, tendendo a melhorar no decorrer do curso; enquanto os demais apresentaram piores resultados nos anos finais, o que pode estar relacionado ao aumento das atividades práticas de estágio. Dentre os achados qualitativos, a escassez de tempo livre e o cansaço foram referidos pelos estudantes como os principais comprometedores da qualidade de vida, corroborando os achados do SF-36, que apresentaram piores resultados para a vitalidade.

Cognitive Functions After Traumatic Brain Injury. A 30-year Follow-up Study

Many cognitive deficits after TBI (traumatic brain injury) are well known, such as memory and concentration problems, as well as reduced information-processing speed. What happens to patients and cognitive functioning after immediate recovery is poorly known. Cognitive functioning is flexible and may be influenced by genetic, psychological and environmental factors decades after TBI. The general aim of this thesis was to describe the long-term cognitive course after TBI, to find variables that may contribute to it, and how the cognitive functions after TBI are associated with specific medical factors and reduced survival. The original study group consisted of 192 patients with TBI who were originally assessed with the Mild Deterioration Battery (MDB) on average two years after the injury, during the years 1966 – 1972. During a 30-year follow-up, we studied the risks for reduced survival, and the mortality of the patients was compared with the general population using the Standardized Mortality Ratio (SMR). Sixty-one patients were re-assessed during 1998-2000. These patients were evaluated with the MDB, computerized testing, and with various other neuropsychological methods for attention and executive functions. Apolipoprotein-E (ApoE) genotyping and magnetic resonance imaging (MRI) based on volumetric analysis of the hippocampus and lateral ventricles were performed. Depressive symptoms were evaluated with the short form of the Beck depression inventory. The cognitive performance at follow-up was compared with a control group that was similar to the study group in regard to age and education. The cognitive outcome of the patients with TBI varied after three decades. The majority of the patients showed a decline in their cognitive level, the rest either improved or stayed at the same level. Male gender and higher age at injury were significant risk factors for the decline. Whereas most cognitive domains declined during the follow-up, semantic memory behaved in the opposite way, showing recovery after TBI. In the follow-up assessment, the memory decline and impairments in the set-shifting domain of executive functions were associated with MRI-volumetric measures, whereas reduction in information-processing speed was not associated with the MRI measures. The presence of local contusions was only weakly associated with cognitive functions. Only few cognitive methods for attention were capable of discriminating TBI patients with and without depressive symptoms. On the other hand, most complex attentional tests were sensitive enough to discriminate TBI patients (non-depressive) from controls. This means that complex attention functions, mediated by the frontal lobes, are relatively independent of depressive symptoms post-TBI. The presence of ApoE4 was associated with different kinds of memory processes including verbal and visual episodic memory, semantic memory and verbal working memory, depending on the length of time since TBI. Many other cognitive processes were not affected by the presence of ApoE4. Age at injury and poor vocational outcome were independent risk factors for reduced survival in the multivariate analysis. Late mortality was higher among younger subjects (age < 40 years at death) compared with the general population which should be borne in mind when assessing the need for rehabilitation services and long-term follow-up after TBI.
