Long-term Disability (long-term + disability)
Selected AbstractsRegular or "Super-Aspirins"?JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2001A Review of Thienopyridines or Aspirin to Prevent Stroke PURPOSE: To review the evidence for the effectiveness and safety of the thienopyridines (ticlopidine and clopidogrel) compared with aspirin for the prevention of vascular events among patients at high risk of vascular disease. BACKGROUND: Atherosclerosis and resultant cardiovascular disease are important causes of morbidity and mortality in older people. In particular, atherosclerosis of the cerebral arteries can lead to transient ischemic attacks (TIAs) and stroke. Stroke ranks as the third-leading cause of death in the United States and in 1997 was responsible for over 150,000 fatalities.1 In addition to the mortality associated with this disease, stroke is also a leading source of long-term disability in survivors. Nearly 4.5 million stroke survivors are alive today,1 highlighting the fact that primary, but also secondary, prevention are extremely important for minimizing the complications of this illness. DATA SOURCES: Specialized trial registers of the Cochrane Stroke Group and the Antithrombotic Trialist's Collaboration, MEDLINE, and Embase were searched. Additional unpublished information and data were sought from Sanofi, the pharmaceutical company that developed and manufactures ticlopidine and clopidogrel, as well as the principal investigators of the Clopidogrel versus Aspirin in Patients at Risk of Ischemic Events (CAPRIE) trial,7 the largest of the trials identified. STUDY SELECTION CRITERIA: All unconfounded randomized trials comparing either ticlopidine or clopidogrel with aspirin among patients at high risk of vascular disease (those with symptoms of ischemia of the cerebral, coronary, or peripheral circulations) who were followed for at least 1 month for the recurrence of vascular events were included. DATA EXTRACTION: Data were extracted from four completed randomized trials completed in the past 20 years, which included 22,656 patients.7,10 Two authors independently extracted the data from these trials for the following information: the types of patients enrolled; the entry and exclusion criteria; the randomization method; the number of patients originally allocated to the treatment and control groups; the method and duration of follow-up; the number of patients in each group lost to follow-up; information on compliance with the treatment allocated; the definitions of outcome events; the number of outcome events in each treatment group; and any method used for blinding patients, treating clinicians, and outcome assessors to treatment allocation. MAIN RESULTS: Four completed trials involving a total of 22,656 patients were identified. Aspirin was compared with ticlopidine in three trials (3,471 patients)8,10 and with clopidogrel in one trial (19,185 patients).7 A recent TIA or ischemic stroke was the qualifying event in 9,840 patients, a recent myocardial infarction in 6,302 patients, and symptomatic peripheral arterial disease in 6,514 patients. The average age of the patients was approximately 63, with approximately two-thirds of the patients being male and white. The duration of follow-up ranged from 12 to 40 months. CONCLUSIONS: This systematic review demonstrates that, compared with aspirin, thienopyridines are only modestly more effective in preventing serious vascular events in high-risk patients. For patients who are intolerant of, or allergic to aspirin, the available safety and efficacy data suggest that clopidogrel is an appropriate, but more-expensive, alternative antiplatelet drug. It appears safer than ticlopidine and as safe as aspirin but it should not replace aspirin as the first-choice antiplatelet agent for all patients. Further studies are necessary to determine which, if any, particular types of patients would benefit most and least from clopidogrel instead of aspirin. [source] Ethical issues for parents of extremely premature infantsJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 5 2008Judith Schroeder Abstract: Evidence suggests that NICU (neonatal intensive care unit) parents with an baby born at the threshold of viability do not always receive sufficient counselling during an emergency admission and as a consequence, are not well-informed to accept withdrawal of treatment or quality of life decisions. As prospective parents are not educated earlier in pregnancy about extreme premature delivery, crucial information and counselling explaining neonatal issues is only offered to labouring women during their emergency admission. As a result, most have difficulty understanding the risks and benefits of baby's treatment and therefore rely heavily on the perinatal physician to take responsibility for the initial treatment. However, this lack of understanding often leaves parents disadvantaged, as many are left unprepared to participate objectively in quality of life decisions. According to recent research, morbidity figures remain relatively high with one in five survivors at risk of a long-term disability. This shows that some parents will still be confronted by ethical decision of whether or not to continue treatment, and this may not be apparent until days after treatment has been established. As recent research has shown, parents do, in fact, want increased involvement in the decision-making process regarding their child's treatment. Therefore, it has been argued, that parents should be provided with information earlier in pregnancy to familiarise themselves with quality of life issues which they may encounter as the NICU parents of an extremely premature infant. [source] Clinical review: Healing in gastrointestinal anastomoses, Part IMICROSURGERY, Issue 3 2006Sarah K. Thompson M.D. Gastrointestinal healing is a topic rarely reviewed in the literature, yet it is of paramount importance to the surgeon. Failure of anastomotic healing may lead to life-threatening complications, additional surgical procedures, increased length of stay, increased cost, long-term disability, and reduced quality of life for the patient. The goal of this article is to review the biological response to wounded tissue, to outline discrete differences between skin and gastrointestinal healing, to discuss local and systemic factors important to gastrointestinal healing, and to compare methods of measuring collagen content and strength of the newly formed anastomosis. Part II of this review will focus on techniques and therapies available to optimize anastomotic healing. © 2006 Wiley-Liss, Inc. Microsurgery, 2006. [source] Evaluating the efficacy of tele-cognitive rehabilitation for functional performance in three case studiesOCCUPATIONAL THERAPY INTERNATIONAL, Issue 1 2003Dr Sing-Fai Tam PhD Associate Professor Abstract Traumatic brain injury (TBI) is one of the main causes of long-term disability, and its rehabilitation is a challenge to the healthcare team. Tele-rehabilitation, through using advancements in networking and tailor-made software, has been developed and applied to the cognitive rehabilitation of persons with brain injury in the present study. Tele-cognitive rehabilitation uses customized online computer software as a treatment mode. The online treatment software is operated on an interactive tele-communication platform , for example, video conferencing with screen sharing. Through implementing the tele-cognitive rehabilitation activities, therapists can help clients to practise and thus improve their cognitive skills through using the treatment software successfully. Moreover, hypermedia programming techniques allow the therapist to adjust the software to meet the client's treatment needs, so that the treatment is appropriate to his/her functional levels and living environment. Also the software can customize immediate visual, auditory and personalized feedback to motivate the client and training can be set at the right pace for the client's needs. The present study aimed to evaluate the effectiveness and perceived efficacy of the newly developed customized tele-cognitive rehabilitation programme for three subjects with traumatic brain injury through using single-case and qualitative research design. The cognitive factors investigated in this pilot study were, respectively, Chinese word recognition, prospective memory and semantic memory. The subjects had undergone a recruitment process with stipulated screening criteria. A single case experimental design (ABA reversal/withdrawal design) consisted of a no-intervention baseline phase (A), an intervention phase (B) and a no-intervention withdrawal phase (A). There were six sessions in each phase, making a total of 18 sessions. Tele-cognitive rehabilitation software was tailor-made according to each subject's cognitive functional needs. To monitor the change in cognitive functions, variables were tapped by tailor-made assessment and qualitative questionnaires through interviews, and they were then used to explore subjects' opinions of the programme and to test the treatment efficacy of the tele-cognitive rehabilitation programme. Finally, the relationships among the three phases were analysed through visual analysis and trend line analysis by means of the split-middle method. The three persons with brain injury showed improving trends and levels of specific cognitive performance during the treatment phase. Qualitative findings were analysed and confirmed the efficacy of the treatment module. The tele-cognitive rehabilitation approach was well received by subjects. The authors suggest that further replication studies of this kind should be conducted in the future and that more subjects should be recruited to improve the generalizability of the results.

Ryan MD Abstract Objectives/Hypothesis: To clarify the extent and patient perspectives of great auricular nerve (GAN) morbidity and recovery after nerve sacrifice during parotidectomy 4 to 5 years after surgery. Study Design: Prospective series. Methods: Twenty-two patients who underwent parotidectomy with GAN sacrifice and were previously studied for GAN sensory outcome during the first postoperative year. We performed light touch sensation tests on each patient to develop an ink map representing anesthesia and paresthesia in the GAN sensory territory; patients also completed an outcomes questionnaire. Results: Nineteen (86%) of 22 patients completed follow-up. One patient completed the questionnaire over the phone. The prevalence and average areas of anesthesia and paresthesia decreased since the first postoperative year according to sensory testing and patient scoring. At 4 to 5 years, 47% (9 of 19) of the patients had anesthesia, 58% (11 of 19) had paresthesia, and 26% (5 of 19) had neither anesthesia nor paresthesia during sensory testing. Patients reported that the GAN dysfunction brought them no to mild inference with their daily activities. At a mean point of 2 years, 70% (14 of 20) patients felt that their sensory symptoms had either completely abated or stabilized. Conclusions: The posterior branch of the GAN should be preserved if it does not compromise tumor resection. If this is not possible, the patient and surgeon should be comforted in that only minor, if any, long-term disability will ensue. Laryngoscope, 2009 [source] A review of paroxysmal sympathetic hyperactivity after acquired brain injuryANNALS OF NEUROLOGY, Issue 2 2010Iain Perkes BMedSc Severe excessive autonomic overactivity occurs in a subgroup of people surviving acquired brain injury, the majority of whom show paroxysmal sympathetic and motor overactivity. Delayed recognition of paroxysmal sympathetic hyperactivity (PSH) after brain injury may increase morbidity and long-term disability. Despite its significant clinical impact, the scientific literature on this syndrome is confusing; there is no consensus on nomenclature, etiological information for diagnoses preceding the condition is poorly understood, and the evidence base underpinning our knowledge of the pathophysiology and management strategies is largely anecdotal. This systematic literature review identified 2 separate categories of paroxysmal autonomic overactivity, 1 characterized by relatively pure sympathetic overactivity and another group of disorders with mixed parasympathetic/sympathetic features. The PSH group comprised 349 reported cases, with 79.4% resulting from traumatic brain injury (TBI), 9.7% from hypoxia, and 5.4% from cerebrovascular accident. Although TBI is the dominant causative etiology, there was some suggestion that the true incidence of the condition is highest following cerebral hypoxia. In total, 31 different terms were identified for the condition. Although the most common term in the literature was dysautonomia, the consistency of sympathetic clinical features suggests that a more specific term should be used. The findings of this review suggest that PSH be adopted as a more clinically relevant and appropriate term. The review highlights major problems regarding conceptual definitions, diagnostic criteria, and nomenclature. Consensus on these issues is recommended as an essential basis for further research in the area. ANN NEUROL 2010;68:126,135 [source] Gray matter atrophy is related to long-term disability in multiple sclerosisANNALS OF NEUROLOGY, Issue 3 2008Leonora K. Fisniku MRCP Objective To determine the relation of gray matter (GM) and white matter (WM) brain volumes, and WM lesion load, with clinical outcomes 20 years after first presentation with clinically isolated syndrome suggestive of multiple sclerosis (MS). Methods Seventy-three patients were studied a mean of 20 years from first presentation with a clinically isolated syndrome (33 of whom developed relapsing-remitting MS and 11 secondary-progressive MS, with the rest experiencing no further definite neurological events), together with 25 healthy control subjects. GM and WM volumetric measures were obtained from three-dimensional T1-weighted brain magnetic resonance images using Statistical Parametric Mapping 2. Results Significant GM (p < 0.001) and WM atrophy (p = 0.001) was seen in MS patients compared with control subjects. There was significantly more GM, but not WM atrophy, in secondary-progressive MS versus relapsing-remitting MS (p = 0.003), and relapsing-remitting MS versus clinically isolated syndrome (p < 0.001). GM, but not WM, fraction correlated with expanded disability status scale (rs = ,0.48; p < 0.001) and MS Functional Composite scores (rs = 0.59; p < 0.001). WM lesion load correlated with GM (rs = ,0.63; p < 0.001), but not with WM fraction. Regression modeling indicated that the GM fraction explained more of the variability in clinical measures than did WM lesion load. Interpretation In MS patients with a relatively long and homogeneous disease duration, GM atrophy is more marked than WM atrophy, and reflects disease subtype and disability to a greater extent than WM atrophy or lesions. Ann Neurol 2008 [source] Functioning and disability 6,15 years after traumatic brain injuries in northern SwedenACTA NEUROLOGICA SCANDINAVICA, Issue 6 2009L. J. Jacobsson Objectives,, To assess long-term functioning and disability after traumatic brain injury (TBI). Material and methods,, Individuals (n = 88) in Norrbotten, northern Sweden, who had been transferred for neurosurgical care were assessed with internationally established TBI outcome measures 6,15 years post-injury. Results,, There was an improvement in overall outcome from discharge from inpatient rehabilitation to follow-up. Many individuals had a high degree of motor and cognitive functioning, which enabled them to live independently in their own home without assistance, but there remained a disability related to community reintegration and social participation. This affected their productivity and to some degree their marital stability. The remaining disability and reduced productivity were related to the age at injury and the injury severity. Conclusions,, Our data showed that individuals with a TBI can achieve and maintain a high degree of functioning many years after the injury. Increasing age and a greater injury severity contributed to their long-term disability. [source] Corticosteroids in the treatment of multiple sclerosisACTA NEUROLOGICA SCANDINAVICA, Issue 2009K. M. Myhr Background ,, Multiple sclerosis (MS) is an immune-mediated inflammatory disease of the central nervous system (CNS) that usually is clinically characterized by repeated subacute relapses followed by remissions. Therapeutic strategies include corticosteroid treatment of relapses and immunomodulatory- or immunosuppressive treatment to prevent new relapses and progression of disability. Objectives ,, To review the evidences for the use of corticosteroids in the treatment of relapses in MS as well as its possible disease modifying potential. Materials & Methods ,, Available literature from PubMed search and personal experiences on corticosteroid treatment in multiple sclerosis were reviewed. Results ,, High dose short-term oral or intravenous methylprednisolone for 3-5 days speed up recovery from relapses, but the treatment has no influence on the occurrence of new relapses or long-term disability. There is also some evidence that pulsed treatment with methylprednisolone have beneficial long-term effects in multiple sclerosis. Conclusion ,, Relapses with moderate to serious disability should be treated with high dose intravenous or oral methylprednisolone. More data is needed to determine long-term disease modifying effects of corticosteroids. [source] | ||||||||||
