Neuropsychological rehabilitation of memory deficits and activities of daily living in patients with Alzheimer's disease: a pilot study

Patients with Alzheimer's disease (AD) gradually lose their cognitive competence, particularly memory, and the ability to perform daily life tasks. Neuropsychological rehabilitation is used to improve cognitive functions by facilitating memory performance through the use of external aids and internal strategies. The effect of neuropsychological rehabilitation through memory training - motor movements, verbal association, and categorization - and activities of daily living (ADL) training was tested in a sample of 5 elderly out-patients (mean age: 77.4 ± 2.88 years), with mild AD (Mini-Mental State Examination score: 22.20 ± 2.17) and their caregivers. All patients had been taking rivastigmine (6-12 mg/day) for at least 3 months before being assigned to the rehabilitation sessions, and they continued to take the medication during the whole program. Just before and after the 14-week neuropsychological rehabilitation program all patients were assessed by interviewers that did not participate in the cognitive training, using the Mini-Mental State Examination, Montgomery-Alsberg Depression Rating Scale, Hamilton Anxiety Scale, Interview to Determine Deterioration in Functioning in Dementia, Functional Test, Memory Questionnaire of Daily Living for patient and caregiver, Quality of Life Questionnaire for patient and caregiver, and a neuropsychological battery. The results showed a statistically significant improvement in ADL measured by Functional Test (P = 0.04), and only a small improvement in memory and psychiatric symptoms. Our results support the view that weekly stimulation of memory and training of ADL is believed to be of great value in AD treatment, not only delaying the progress of the disease, but also improving some cognitive functions and ADL, even though AD is a progressively degenerative disease.

Satisfação com a prótese auditiva na vida diária em usuários do Sistema de Saúde do Exército

O objetivo deste estudo foi investigar o nível de satisfação com a prótese auditiva na vida diária em usuários do Sistema de Saúde do Exército e fatores associados. Foram selecionados adultos e idosos, usuários do convênio de saúde da 3ª Região Militar, que adquiriram prótese auditiva entre os anos de 1998 e 2003, para responderem ao questionário SADL (Satisfaction with Amplification in Daily Life). Foram excluídos do estudo indivíduos com idade inferior a 18 anos; que adquiriram a prótese auditiva há menos de 6 semanas; com grave limitação da capacidade de compreensão e expressão; e que não concordaram em participar da pesquisa. Os resultados mostraram que os pacientes estavam consideravelmente satisfeitos com o uso da prótese auditiva. Houve menor satisfação na subescala fatores negativos do SADL, especialmente em relação ao uso do telefone. Tiveram associação com a satisfação fatores ligados à pessoa e, principalmente, à reabilitação auditiva. Os dados mostraram que, além da seleção da prótese tecnicamente mais adequada, tem fundamental importância a implantação de programas de reabilitação auditiva, com experiência domiciliar, orientações e aconselhamento, buscando que o paciente tenha expectativas realistas.

Self-reported hearing performance in workers exposed to solvents

OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz), to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA) were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

Impact of the disease: acceptability, ceiling and floor effects and reliability of an instrument on heart failure

This study evaluated the acceptability, ceiling/floor effects, and the reliability of the instrument for measuring the Impact of the Disease on the Daily Life of Patients with Valvular Disease (IDCV) when applied to 135 patients with heart failure (HF). Acceptability was evaluated by the percentage of unanswered items and by the proportion of patients who responded to all items; the ceiling/floor effects by the percentage of patients who scored in the top of 10% best and worst results of the scale, respectively. Reliability was estimated by internal consistency (Cronbach's alpha coefficient) and stability of the measure (intraclass correlation coefficient - ICC). All patients responded to all items. Ceiling/floor effects evidenced were of moderate magnitude. The Cronbach's alpha was satisfactory for the majority of the domains and ICC> 0.90 in all the domains. The IDCV proved to be an easy to understand questionnaire, with evidence of reliability in patients with HF.

Stress, coping and presenteeism in nurses assisting critical and potentially critical patients

Objective to verify the associations between stress, Coping and Presenteeism in nurses operating on direct assistance to critical and potentially critical patients. Method this is a descriptive, cross-sectional and quantitative study, conducted between March and April 2010 with 129 hospital nurses. The Inventory of stress in nurses, Occupational and Coping Questionnaire Range of Limitations at Work were used. For the analysis, the Kolmogorov-Smirnov test, correlation coefficient of Pearson and Spearman, Chi-square and T-test were applied. Results it was observed that 66.7% of the nurses showed low stress, 87.6% use control strategies for coping stress and 4.84% had decrease in productivity. Direct and meaningful relationships between stress and lost productivity were found. Conclusion stress interferes with the daily life of nurses and impacts on productivity. Although the inability to test associations, the control strategy can minimize the stress, which consequently contributes to better productivity of nurses in the care of critical patients and potentially critical.


MEDICAL STUDENT IN THE FAMILY HEALTH STRATEGY ON THE FIRST YEARS OF COLLEGE: PERCEPTION OF GRADUATES

There is a lack of knowledge about the effective value of the experience gained by medical students who participate in the Family Health Strategy (Estratégia Saúde da Família (ESF)) during the early stages of their medical training. This teaching strategy is based on learning by experiencing the problems that exist in real life. This study proposed to understand the value of this teaching strategy from the viewpoint of the students who had participated, after their graduation. The method adopted was a qualitative study conducted through interviews with students who graduated in the years 2009, 2010 and 2011. The data analysis used the hermeneutic dialectic technique as its model. The graduates considered that this experience enabled them to understand the organization and functioning of the health service and the context of the daily life of the users. This experience facilitated the doctor patient relationship, the development of clinical reasoning and the bond with the user. However the students emphasized that a lack of maturity prevented them gaining a higher level of benefit from the experience. Therefore, although the structure of the course is permeated by advances and challenges, it was concluded that this experience contributed to the student's learning of certain essential elements of medical training.

Skin tear prevalence and associated factors: a systematic review

OBJECTIVETo identify and analyse skin tear prevalence and factors associated with its occurrence.METHODSystematic review of literature of studies published until June 2014 including studies published in full in English, Spanish or Portuguese. The studies were analysed according to the Strengthening the Reporting of Observational Studies in Epidemiology and the Guidelines for Critically Appraising Studies of Prevalence or Incidence of a Health Problem.RESULTSThe analysis of eight studies showed skin tear prevalence of 3.3% to 22% in the hospital setting and 5.5% to 19.5% in homecare. Advanced age, dependence on basic activities of daily life, frail elderly, level of mobility, agitated behavior, non-responsiveness, greater risk for concurrent development of pressure ulcers, cognitive impairment, spasticity and photoaging were cited as risk factors.CONCLUSIONSkin tear prevalence ranged from 3.3% to 22% and is mainly associated with advanced age and dependence on basic activities of daily life.

Social representation of Alzheimer's disease for family caregivers: stressful and rewarding

Abstract OBJECTIVE To understand the content of Social Representation (SR) of family caregivers of Alzheimer's disease patients. METHOD Interviews were conducted with 26 caregivers and analyzed by the ALCESTE software. RESULTS The SR content was structured in two thematic axes called Daily Life and Care and Medical and Emotional Concepts and Outcomes. The first axis creates images related to the routine of interaction with the sick person, and contains a description of care procedures, experiences, and practices applied every day. The second is composed of subjective and conceptual aspects that make up the social representation of Alzheimer's disease, with meanings related to the emotional, medical, and biological contexts. CONCLUSION Due to the importance of topics related to patients' dependence and the personal and emotional consequences of the disease, overload is the main content of the SR of Alzheimer's disease for caregivers, and the understanding of these SR by health professionals should support the planning of interventions addressing this group of individuals.

O uso de calorimetria em ecologia

The macroscopic effects caused by sun radiation and the mankind-nature interactions in a ecosystem are firstly presented. However, the importance of calorimetric determinations to clarify some phenomena related to the living microorganism populations and their interactions with the food additive or inhibitor agents are reported. The collect values illustrate the occurence a great deal of effects in this microscopic world. For this subject, the reachest Latosol soil was selected due to the content of organic matter and consequently in microorganisms. Microbial activity was stimulated by addition of glucose, which showed to be the best nutrient source. Inhibitory effect was detected with many compounds used in the agriculture like some herbicides and fungicides. Although the assays are based on the use of the microcalorimetry, other techniques like respirometry contributes strongly to the understanding of the ecosystem. The main objective in this exposition is to stimulate by means of many interesting examples, the importance of preserving the environment in order to establish direct analogies by using the Chemistry in the daily life.

Effects of chronic heart disease on skeletal muscle fiber size

Size changes in muscle fibers of subjects with chronic heart disease (CHD) have been reported, although a consensus has not been achieved. The aims of the present study were to investigate a possible association between CHD and fiber size changes in the brachial biceps compared to subjects without heart disease. Forty-six muscle samples were obtained in autopsies of individuals (13 to 84 years) without neuromuscular disorders, 19 (10 males and 9 females) with, and 27 (14 males and 13 females) without CHD. In all cases muscle sections were stained with hematoxylin and eosin and processed for the visualization of myofibrillar ATPase activity. The lesser diameter of type 1 and type 2 fibers was obtained tracing their outlines (at least 150 fibers of each type per sample) onto an image analyzer connected to a computer. The results were analyzed statistically comparing males and females with and without CHD. Type 1 fiber mean lesser diameters were 51.51 and 54.52 µm in males (normal range 34-71 µm) and 45.65 and 55.42 µm in females (normal range 34-65 µm) without and with CHD, respectively; type 2 fibers measured 54.31, 58.23, 41.15, and 49.57 µm, respectively (normal range 36-79 µm for males and 32-59 µm for females). No significant difference in fiber size was detected in 24 males with and without CHD, while in 22 females there was a significant increase in size in those with cardiomyopathy. We concluded that CHD does not determine significant changes in fiber size. However, in females, there is some hypertrophy which, despite within normal range, may reflect morphologic heterogeneity of the sample, or the daily life activities in the upper limbs as a compensatory mechanism to fatigability that affect predominantly the lower limbs in subjects with CHD.

Psoriasis severity and hypothalamic-pituitary-adrenal axis function: results from the CALIPSO study

Psoriasis is a chronic inflammatory disease that significantly impacts life quality, being associated with stress and mental disorders. We investigated whether the activity of the hypothalamic-pituitary-adrenal (HPA) axis was associated with psoriasis severity, daily life stress and anxiety, and depressive symptoms. In this ancillary study, which was part of the CALIPSO (coronary artery calcium in psoriasis) study, saliva was collected from 102 patients with psoriasis immediately upon awakening, 30, and 60 min after awakening, at 2:00 pm and at bedtime (five time points) to determine salivary cortisol levels. We used Pearson's correlation coefficient to evaluate the association of clinical and psychopathological variables with HPA activity. We found a direct correlation between bedtime cortisol and psoriasis severity evaluated by the psoriasis area severity index (PASI; r=0.39, P<0.001). No correlations between other clinical and psychopathological variables or with other cortisol assessments were observed. The findings indicated that HPA dysfunction may be present in psoriasis, as bedtime cortisol was correlated with psoriasis severity. Our study is limited by the lack of a control group; therefore, we were not able to explore whether these cortisol values were different compared with a concurrent, healthy sample.
