Acid-base disorders may complicate the presentation of patients with poisoning. This article summarizes an approach to acid-base disorders from a toxicologic perspective. It aims to assist the reader in identifying underlying acid-base processes, generating a differential diagnosis for each, and approaching that differential diagnosis in a systematic fashion. Understanding these processes will help to guide management and interventional strategies. © 2014 Elsevier Inc. Source

Background and Purpose-Purpose in life, the sense that life has meaning and direction, is associated with reduced risks of adverse health outcomes. However, it remains unknown whether purpose in life protects against the risk of cerebral infarcts among community-dwelling older people. We tested the hypothesis that greater purpose in life is associated with lower risk of cerebral infarcts. Methods-Participants came from the Rush Memory and Aging Project. Each participant completed a standard measure of purpose in life. Uniform neuropathologic examination identified macroscopic infarcts and microinfarcts, blinded to clinical information. Association of purpose in life with cerebral infarcts was examined in ordinal logistic regression models using a semiquantitative outcome. Results-Four hundred fifty-three participants were included in the analyses. The mean score on the measure of purpose was 3.5 (SD, 0.5; range, 2.1-5.0). Macroscopic infarcts were found in 154 (34.0%) people, and microinfarcts were found in 128 (28.3%) people. Greater purpose in life was associated with a lower odds of having more macroscopic infarcts (odds ratio, 0.535; 95% confidence interval, 0.346-0.826; P=0.005), but we did not find association with microinfarcts (odds ratio, 0.780; 95% confidence interval, 0.495-1.229; P=0.283). These results persisted after adjusting for vascular risk factors of body mass index, history of smoking, diabetes mellitus, and blood pressure, as well as measures of negative affect, physical activity, and clinical stroke. The association with macroscopic infarcts was driven by lacunar infarcts, and was independent of cerebral atherosclerosis and arteriolosclerosis. Conclusions-Purpose in life may affect risk for cerebral infarcts, specifically macroscopic lacunar infarcts. © 2015 American Heart Association, Inc. Source

Blood transfusions have become indispensable to treat the anemia associated with a variety of medical conditions ranging from genetic disorders and cancer to extensive surgical procedures. In developed countries, the blood supply is generally adequate. However, the projected decline in blood donor availability due to population ageing and the difficulty in finding rare blood types for alloimmunized patients indicate a need for alternative red blood cell (RBC) transfusion products. Increasing knowledge of processes that govern erythropoiesis has been translated into efficient procedures to produce RBC ex vivo using primary hematopoietic stem cells, embryonic stem cells, or induced pluripotent stem cells. Although in vitro-generated RBCs have recently entered clinical evaluation, several issues related to ex vivo RBC production are still under intense scrutiny: among those are the identification of stem cell sources more suitable for ex vivo RBC generation, the translation of RBC culture methods into clinical grade production processes, and the development of protocols to achieve maximal RBC quality, quantity, and maturation. Data on size, hemoglobin, and blood group antigen expression and phosphoproteomic profiling obtained on erythroid cells expanded ex vivo from a limited number of donors are presented as examples of the type of measurements that should be performed as part of the quality control to assess the suitability of these cells for transfusion. New technologies for ex vivo erythroid cell generation will hopefully provide alternative transfusion products to meet present and future clinical requirements. © AlphaMed Press. Source

Complications from uncontrolled diabetes mellitus were reduced significantly with the introduction of insulin more than 90 years ago. Despite the proven benefits of normal glycemic levels, patients are deterred by the inconvenience and perceived pain related to multiple daily subcutaneous insulin injections. Inhaled insulin was first approved by the U.S. Food and Drug Administration (FDA) in 2006, but because profit margins did not achieve expectations, the drug manufacturer discontinued sales 2 years later. The second-generation inhaled insulin, developed with Technosphere technology, received FDA approval in 2014. The pharmacology, pharmacokinetics, drug interactions, clinical safety and efficacy, patient satisfaction, dosage and administration, warnings, precautions, contraindications, adverse effects, and place in therapy of inhaled Technosphere insulin are reviewed in this article. © 2015 Pharmacotherapy Publications, Inc.

Thrombolysis with alteplase administered within a narrow therapeutic window provides an effective therapy for acute ischaemic stroke. However, mainly because of prehospital delay, patients often arrive too late for treatment, and no more than 1-8% of patients with stroke obtain this treatment. We recommend that all links in the prehospital stroke rescue chain must be optimised so that in the future more than a small minority of patients can profit from time-sensitive acute stroke therapy. Measures for improvement include continuous public awareness campaigns, education of emergency medical service personnel, the use of standardised, validated scales for recognition of stroke symptoms and for triaging to the appropriate institution, and advance notification to the receiving hospital. In the future, use of telemedicine technologies for interaction between the emergency site and hospital, and the strategy of treatment directly at the emergency site (mobile stroke unit concept), could contribute to more efficient use of resources and reduce the time taken to instigate treatment to within 60 min-the golden hour-of the onset of the symptoms of stroke. © 2013 Elsevier Ltd.
