TL;DR: Age, SAPS II and length of ICU stay were significantly higher in patients Dying patients who had therapy withheld or withdrawn than in patients dying despite active treatment.
Abstract: Objective: To determine how frequently life support is withheld or withdrawn from adult critically ill patients, and how physicians and patients families agree on the decision regarding the limitation of life support. Design: Prospective multi-centre cohort study. Setting: Six adult medical-surgical Spanish intensive care units (ICUs). Patients and participants: Three thousand four hundred ninety-eight consecutive patients admitted to six ICUs were enrolled. Measurements and results: Data collected included age, sex, SAPS II score on admission and within 24 h of the decision to limit treatment, length of ICU stay, outcome at ICU discharge, cause and mode of death, time to death after the decision to withhold or withdraw life support, consultation and agreement with patient's family regarding withholding or withdrawal, and the modalities of therapies withdrawn or withheld. Two hundred twenty-six (6.6%) of 3,498 patients had therapy withheld or withdrawn and 221 of them died in the ICU. Age, SAPS II and length of ICU stay were significantly higher in patients dying patients who had therapy withheld or withdrawn than in patients dying despite active treatment. The proposal to withhold or withdraw life support was initiated by physicians in 210 (92.9%) of 226 patients and by the family in the remaining cases. The patient's family was not involved in the decision to withhold or withdraw life support therapy in 64 (28.3%) of 226 cases. Only 21 (9%) patients had expressed their wish to decline life-prolonging therapy prior to ICU admission. Conclusions: The withholding and withdrawing of treatment was frequent in critically ill patients and was initiated primarily by physicians.

TL;DR: Management of colorectal obstruction by using metallic stents was effective and safe, although colonic perforation is a potential complication, and the method may obviate palliative colostomy.
Abstract: PURPOSE: To determine the effectiveness and safety of metallic stents in the treatment of malignant colorectal obstruction before surgery and for palliation. MATERIALS AND METHODS: Eighty patients with acute malignant colorectal obstruction presumed to be malignant were treated by means of implanting self-expanding metallic stents. RESULTS: Stent placement was successful in 70 of the 80 patients and resolved bowel obstruction in 67 patients (96%). Two patients had colonic perforation and developed peritonitis 18 and 24 hours after stent placement; one patient died as a consequence. Thirty-three patients underwent elective surgery after 7 days ± 3 (SD; range, 4–10 days), and adequate tumoral coverage and cleansing of the colon were observed in all patients. Stent placement was used as final palliative treatment in another 35 patients. Patient follow-up lasted a mean of 138 days ± 93 (range, 36–334 days). The survival rate for the palliative group was 55% at 3 months, 44% at 6 months, and 25% at 9 months. T...

TL;DR: The clinical efficacy of nimodipine for the symptoms of dementia, either unclassified or according to the major subtypes - Alzheimer's disease, vascular, or mixed Alzheimer's and vascular dementia is determined.
Abstract: Background Dementia is an age-related condition in which Alzheimer's disease (AD) and cerebrovascular disease account for the bulk of cases. The role played by calcium in regulating brain functions is well known - the calcium ion links membrane excitation to subsequent intracellular enzymatic response. Change in calcium homeostasis is one important effect of aging with repercussions on higher cortical functions. Nimodipine is an isopropyl calcium channel blocker which can easily cross the blood brain barrier. Its primary action is to reduce the number of open channels, thus restricting influx of calcium ions into the cell. The usefulness of nimodipine in patients with Alzheimer's disease and vascular dementia and unspecified dementia is still controversial with mixed results. In spite of the uncertainties about its efficacy in dementia, nimodipine is currently a frequently prescribed drug for cognitive impairment and dementia in several European countries. This review will be conducted in two phases; the current review is based on evidence from published data only. The second phase will be based on individual-patient data analysed centrally and added to this review in due course. Objectives To determine the clinical efficacy of nimodipine for the symptoms of dementia, either unclassified or according to the major subtypes - Alzheimer's disease, vascular, or mixed Alzheimer's and vascular dementia. Search strategy The Cochrane Dementia Group Register of Clinical Trials was searched using the terms 'nimodipine' and 'isopropyl (2-methoxy-ethyl) 1,4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3, 5-pyridinedicarboxylate'. Selection criteria All unconfounded, double-blind, randomised trials in which treatment with nimodipine was administered for more than a day and compared to placebo in patients with dementia, either unclassified or according to the major subtypes - Alzheimer's disease, vascular, or mixed Alzheimer's and vascular dementia. Data collection and analysis Data were extracted independently by the reviewers and the odds ratio (95%CI) or the average difference (95%CI) were estimated. Both intention-to-treat and on-treatment results were extracted. Main results This review produced no clear results. Many of the data published were not capable of being sensibly pooled. The data were compatible with nimodipine producing improvement, no change or even harm for those with Alzheimer's disease, vascular dementia, or mixed Alzheimer's and vascular dementia. It was not possible to use many of the published results in a combined analysis. For measures of overall clinical improvement, the intention-to-treat analysis, based on one study only, failed to detect any difference between nimodipine and placebo (OR 0.53; 95%CI 0.25 - 1.13). An on-treatment analysis, based on one study only, produced a statistically significant difference in favour of nimodipine (SMD 4.4; 95%CI 3.9 - 5.0). For cognitive function, the effect of nimodipine was statistically significantly different from placebo for the Mini Mental State Examination score (0-30; high =good) (SMD 0.9; 95%CI 0.59 - 1.22) and there was a statistically significant effect in favour of treatment for the Wechsler Memory Scale (SMD 0.47; 95%CI 0.17 - 0.77). These analyses were based only on those who completed the study and not intention-to-treat analyses. There were no results presented in a form suitable for pooling for functional autonomy, behaviour, quality of life dependency (eg institutionalization), effect on carer, death, acceptability of treatment (as measured by withdrawal rate, safety (as measured by the incidence of adverse effects, including side effects, leading to withdrawal). Reviewer's conclusions This review provides no convincing evidence that nimodipine is a useful treatment for the symptoms of dementia, either unclassified or according to the major subtypes - Alzheimer's disease, vascular, or mixed Alzheimer's and vascular dementia. However, as so few of the trials presented data in a format suitable for pooling, the results of this review may be modified when further data from all relevant trials are included. There is an urgent need for the independent evaluation of the data already existing in the trials but not accessible through published or grouped data. An independent meta-analysis of the individual patient data is required. Nimodipine cannot be currently recommended in patients with dementia. The results and conclusions of this update are unaltered by further searching as the additional studies do not add any further valid/eligible data.
