This paper uses the standard error of measurement (SEM) and the standard error of the difference (S(diff)) in relation to data on individuals with amyotrophic lateral sclerosis (ALS) to calculate the minimum change scores required by statistical criteria for each dimension of the Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40). Data collected from a longitudinal study was used to evaluate the usefulness of SEM and S(diff) criteria and to compare these criteria with an anchor-based approach in determining meaningful change. Questionnaires were completed on two occasions, 3 months apart. 764 questionnaires were returned. Questionnaires included the ALSAQ-40 and dimension specific transition items. The ALSAQ-40 is a disease specific health-related quality of life instrument for use in studies of patients with ALS or other motor neuron diseases. For all dimensions of the ALSAQ-40 the patterns of SEMs were similar over time. The results suggest that, for example, six points change on a 0-100 transformed scoring of the physical mobility dimension may be considered on distributional grounds a minimum meaningful change. The demonstrated consistency of SEMs for the dimensions of the ALSAQ-40 is empirical evidence of the theoretically claimed advantage of this measure of sample independence, and supports use of this distributional approach to calculate meaningful change. 相似文献

AbstractA 44-year-old patient died from amyotrophic lateral sclerosis (ALS) after nine years of heavy exposure to cadmium (Cd) in a nickel-cadmium (Ni-Cd) battery factory. Two years after starting work he and co-workers had experienced pruritus, loss of smell, nasal congestion, nosebleeds, cough, shortness of breath, severe headaches, bone pain, and proteinuria. Upper back pain and muscle weakness progressed to flaccid paralysis. EMG findings were consistent with motor neuron disease. Cd impairs the blood-brain barrier, reduces levels of brain copper-zinc (Cu–Zn) superoxide dismutase (SOD), and enhances excitoxicity of glutamate via up-regulation of glutamate dehydrogenase and down-regulation of glutamate uptake in glial cells. High levels of methallothionein, a sign of exposure to heavy metals, have been found in brain tissue of deceased ALS patients. The effects of Cd on enzyme systems that mediate neurotoxicity and motor neuron disease suggest a cause-effect relationship between Cd and ALS in this worker. 相似文献

Background
Occupation has been suggested to play a role in amyotrophic lateral sclerosis (ALS) etiology, but detailed information on the importance of specific workplace exposures is lacking.Objectives
Our aim was to assess the relationship between workplace exposures and the risk of ALS and to evaluate potential interactions between these exposures and smoking.Methods
We conducted a case–control study in New England between 1993 and 1996, comprising 109 cases and 253 controls who completed a structured interview covering occupations and workplace exposures. Unconditional logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for ALS. Analyses were conducted among the entire study population and after stratification by smoking.Results
We observed a higher risk of ALS for construction workers excluding supervisors (OR = 2.9; 95% CI, 1.2–7.2) and precision metal workers (OR = 3.5; 95% CI, 1.2–10.5). Self-reported exposures to paint strippers; cutting, cooling, or lubricating oils; antifreeze or coolants; mineral or white spirits; and dry cleaning agents each appeared to be associated with a 60–90% higher risk. Specific chemicals related to a > 50% increase in risk of ALS included aliphatic chlorinated hydrocarbons, glycols, glycol ethers, and hexane. Relative risks associated with these workplace exposures and chemicals were greater among nonsmokers and persisted in mutually adjusted models.Conclusions
Our data suggest that certain occupations and workplace exposures may be associated with increased risk of ALS. These results need to be confirmed in independent populations. 相似文献14.

ObjectivesReexamine cost-effectiveness of riluzole in the treatment of amyotrophic lateral sclerosis (ALS) in light of recent advances in disease staging and understanding of stage-specific drug effect.MethodsALS was staged according to the “fine’til 9” (FT9) staging method. Stage-specific health utilities (EQ-5D, US valuation) were estimated from an institutional cohort, whereas literature informed costs and transition probabilities. Costs at 2018 prices were disaggregated into recurring costs (RCs) and “one-off” transition/“tollgate” costs (TCs). Five- and 10-year horizons starting in stage 1 disease were examined from healthcare sector and societal perspectives using Markov models to evaluate riluzole use, at a threshold of $100 000/quality-adjusted life year (QALY). Probabilistic and deterministic sensitivity analyses were conducted.ResultsMean EQ-5D utilities for stages 0 to 4 were 0.79, 0.74, 0.63, 0.54, and 0.46, respectively. From the healthcare sector perspective at the 5-year horizon, riluzole use contributed to 0.182 QALY gained at the cost difference of $12 348 ($5403 riluzole cost, $8870 RC and −$1925 TC differences), translating to an incremental cost-effectiveness ratio (ICER) of $67 658/QALY. Transition probability variation contributed considerably to ICER uncertainty (−30.2% to +90.0%). ICER was sensitive to drug price and RCs, whereas higher TCs modestly reduced ICER due to delayed tollgates.ConclusionThis study provides a framework for health economic studies of ALS treatments using FT9 staging. Prospective stage-specific and disaggregated cost measurement is warranted for accurate future cost-effectiveness analyses. Appropriate separation of TCs from RCs substantially mitigates the high burden of background cost of care on the ICER. 相似文献

Previous studies have suggested a close but inconsistent relationship between essential nutrients and the risk of amyotrophic lateral sclerosis (ALS), and whether this association is causal remains unknown. We aimed to investigate the potential causal relation between essential nutrients (essential amino acids, essential fatty acids, essential minerals, and essential vitamins) and the risk of ALS using Mendelian randomization (MR) analysis. Large-scale European-based genome-wide association studies’ (GWASs) summary data related to ALS (assembling 27,205 ALS patients and 110,881 controls) and essential nutrient concentrations were separately obtained. MR analysis was performed using the inverse variance–weighted (IVW) method, and sensitivity analysis was conducted by the weighted median method, simple median method, MR–Egger method and MR–PRESSO method. We found a causal association between genetically predicted linoleic acid (LA) and the risk of ALS (OR: 1.066; 95% CI: 1.011–1.125; p = 0.019). An inverse association with ALS risk was noted for vitamin D (OR: 0.899; 95% CI: 0.819–0.987; p = 0.025) and for vitamin E (OR: 0.461; 95% CI: 0.340–0.626; p = 6.25 × 10−7). The sensitivity analyses illustrated similar trends. No causal effect was observed between essential amino acids and minerals on ALS. Our study profiled the effects of diet-derived circulating nutrients on the risk of ALS and demonstrated that vitamin D and vitamin E are protective against the risk of ALS, and LA is a suggested risk factor for ALS. 相似文献

Amyotrophic Lateral Sclerosis (ALS) is a devastating progressive neurodegenerative disease that affects motor neurons, leading to a relentless paralysis of skeletal muscles and eventual respiratory failure. Although a small percentage of patients may have a longer survival time (up to 10 years), in most cases, the median survival time is from 20 to 48 months. The pathogenesis and risk factors for ALS are still unclear: among the various aspects taken into consideration, metabolic abnormalities and nutritional factors have been the focus of recent interests. Although there are no consistent findings regarding prior type-2 diabetes, hypercholesterolemia and ALS incidence, abnormalities in lipid and glucose metabolism may be linked to disease progression, leading to a relatively longer survival (probably as a result of counteract malnutrition and cachexia in the advanced stages of the disease). Among potential dietary risk factors, a higher risk of ALS has been associated with an increased intake of glutamate, while the consumption of antioxidant and anti-inflammatory compounds, such as vitamin E, n-3 polyunsaturated fatty acids, and carotenoids, has been related to lower incidence. Poor nutritional status and weight loss in ALS resulting from poor oral intake, progressive muscle atrophy, and the potential hypermetabolic state have been associated with rapid disease progression. It seems important to routinely perform a nutritional assessment of ALS patients at the earliest referral: weight maintenance (if adequate) or gain (if underweight) is suggested from the scientific literature; evidence of improved diet quality (in terms of nutrients and limits for pro-inflammatory dietary factors) and glucose and lipid control is yet to be confirmed, but it is advised. Further research is warranted to better understand the role of nutrition and the underlying metabolic abnormalities in ALS, and their contribution to the pathogenic mechanisms leading to ALS initiation and progression. 相似文献

Background: The purpose of this study was to evaluate the safety and usefulness of fluoroscopy‐guided percutaneous gastrostomy (FPG) in patients with amyotrophic lateral sclerosis (ALS) using a large‐profile gastrostomy tube accompanied by the pull technique. This procedure was done without an accompanying endoscopy or gastropexy. Methods: Thirty‐six patients with ALS underwent FPG using a large‐profile gastrostomy tube accompanied by the pull technique. A 24 Fr pull‐type tube was inserted under fluoroscopic guidance into the mouth and pulled to the upper‐abdominal puncture site using a snare. The technical success rate, occurrence of complications, and clinical outcomes were evaluated. Results: The technical success rate was 100%. There were no procedure‐related mortalities or respiratory complications. The mean forced vital capacity of the patients was 732 mL (17.7% of the normal predicted value). During the procedure, 16 patients required ventilator support by nasal mask or tracheostomy. The tube indwelling period ranged from 1 to 24 months (average, 9.3). During this period, all the tubes were maintained in a proper position. In 18 patients, the tube was exchanged after 6 months without any problems. Conclusions: The FPG procedure using a 24 Fr tube and the pull technique shows a high rate of technical success. This procedure has a low risk for respiratory complications because endoscopic guidance is not needed. In addition, gastropexy is not required, which allows a large‐profile catheter to be inserted during a single procedure. 相似文献

Dysphagia is a highly prevalent symptom in Amyotrophic Lateral Sclerosis (ALS), and the implantation of a percutaneous endoscopic gastrostomy (PEG) is a very frequent event. The aim of this study was to evaluate the influence of PEG implantation on survival and complications in ALS. An interhospital registry of patients with ALS of six hospitals in the Castilla-León region (Spain) was created between January 2015 and December 2017. The data were compared for those in whom a PEG was implanted and those who it was not. A total of 93 patients were analyzed. The mean age of the patients was 64.63 (17.67) years. A total of 38 patients (38.8%) had a PEG implantation. An improvement in the anthropometric parameters was observed among patients who had a PEG from the beginning of nutritional follow-up compared to those who did not, both in BMI (kg/m2) (PEG: 0 months, 22.06; 6 months, 23.04; p < 0.01; NoPEG: 0 months, 24.59–23.87; p > 0.05). Among the deceased patients, 38 (40.4%) those who had an implanted PEG (20 patients (52.6%) had a longer survival time (PEG: 23 (15–35.5) months; NoPEG 11 (4.75–18.5) months; p = 0.01). A PEG showed a survival benefit among ALS patients. Early implantation of a PEG produced a reduction in admissions associated with complications derived from it. 相似文献

People with amyotrophic lateral sclerosis become dependent on caregivers for daily activities and to perform self-care activities at home. The family caregiver has an important role in the care. The patient decides and controls care but depends on the caregiver to implement self-care behaviours. The quality of caregiver–patient relationships could influence clinical outcomes, as it occurs in other illnesses, so the aim of this study was to investigate the relationship between the Amyotrophic Lateral Sclerosis patients and their family caregiver and how it impacts care, and patient and caregiver outcomes. We interviewed 22 patients/caregivers in a Neuromuscular Clinical Center in the South of Europe, between July and October 2018. A Grounded Theory approach was used, comprising line by line ‘initial coding’, memos writing, ‘focused coding’, advanced memos and categories definition. From the interviews three main categories emerged: ‘reciprocity’, ‘loving to care’ and ‘changing to care’ and four secondary categories: ‘having support’, ‘sharing suffering’, ‘protecting each other’ and ‘thinking positive’. A stable and calm relationship between patient and caregiver, characterised by reciprocity, mutual help and affection affected patient self-care provided at home and the caregiver burden. The concept of mutuality seems to describe this relationship, despite the patient's dependence on the caregiver. The relationship with health professionals and educational interventions could influence the quality of the relationship. Further studies are needed to describe the quality of the relationship in this dyad, to investigate the presence of mutuality and how it affects patient and caregiver outcomes. 相似文献
