Aneurismal subarachnoid hemorrhage in a Chilean population, with emphasis on risk factors

<p>Abstract</p> <p>Background</p> <p>Subarachnoid Hemorrhage (SAH) is caused principally by the rupture of intracranial aneurisms. Important risk factors have been described such as age, sex, hypertension (HT) and season of the year, among others. The objective is to investigate the demographic characteristics and possible risk factors in a population of Chilean patients.</p> <p>Methods</p> <p>This retrospective study was based on the analysis of 244 clinical records of patients diagnosed with aneurismal SAH who were discharged from the Instituto de Neurocirugía ASENJO in Santiago, Chile.</p> <p>Results</p> <p>The mean age of patients was 49.85 years and the male:female ratio was 1:2.7. The signs and symptoms were not different between sexes; cephalea (85.7%) was predominant, followed by loss of consciousness, vomiting/nausea and meningeal signs. Risk factors included sex, age and HT. Concordant with other reports, the incidence of SAH was greatest in spring.</p> <p>Conclusions</p> <p>The demographic characteristics and risk factors observed in patients with aneurismal SAH treated in ASENJO were comparable to those of other populations. We were not able to conclude that tobacco and alcohol consumption were risk factors for this population.</p

Independent risk factors for anemia in cancer patients receiving chemotherapy: Results from the European Cancer Anaemia Survey

Objectives: To develop a hitherto unavailable risk factor model for accurately predicting anemia development in cancer patients before chemotherapy (CT) administration. Methods: 2,070 nonanemic patients from the European Cancer Anaemia Survey (ECAS) with hemoglobin (Hb) ≥12 g/dl at enrollment who received their first CT during ECAS and underwent at least two CT cycles were divided randomly into split half (SH) 1 and SH2 (n = 1,035 each). The model was developed on SH1 using logistic regression to simultaneously evaluate predictive factors, and was validated using SH2 and an additional similar subpopulation of 5,901 ECAS patients. Anemia risk values were assigned to the predictive factors and the sum of the predictive factors gave the total anemia risk score; lower-, higher-, and highest-risk cutoff points of the total anemia risk score were determined. Results: Variables ultimately identified as significant predictive factors for anemia were: lower initial Hb (≤12.9 g/dl in females, and ≤13.4 g/dl in males); having lung or gynecologic cancer versus gastrointestinal (GI)/colorectal cancer; cancer at any other site versus GI/colorectal cancer; treatment with platinum CT, and female gender. Conclusion: Using this evidence-based risk model, nonanemic patients who are at the highest risk of develop ing anemia prior to receiving CT can be identified clinically, allowing appropriate anemia management to be planned

An evaluation of dog-assisted therapy for residents of aged care facilities with dementia

Although some research suggests that dog-assisted therapy may be beneficial for people with dementia living in residential aged care facilities, the intervention has not been adequately investigated. To address this shortcoming, we conducted a randomized controlled trial of dog-assisted therapy versus a human-therapist-only intervention for this population. Fifty-five residents with mild to moderate dementia living in three Australian residential aged care facilities completed an 11-week trial of the interventions. Allocation to the intervention was random and participants completed validated measures of mood, psychosocial functioning, and quality of life (QOL), both prior to and following the intervention. No adverse events were associated with the dog-assisted intervention, and following it participants who had worse baseline depression scores demonstrated significantly improved depression scores relative to participants in the human-therapist-only intervention. Participants in the dogassisted intervention also showed significant improvements on a measure of QOL in one facility compared with those in the human-therapist-only group (although worse in another facility that had been affected by an outbreak of gastroenteritis). This study provides some evidence that dog-assisted therapy may be beneficial for some residents of aged care facilities with dementia
