In this paper, a multifractal downscaling technique is applied to adequately transformed and lag corrected normalized difference vegetation index (NDVI) in order to obtain daily estimates of rainfall in an area of the Peruvian Andean high plateau. This downscaling procedure is temporal in nature since the original NDVI information is provided at an irregular temporal sampling period between 8 a...

BACKGROUND Ethnicity has been associated with variance in warfarin treatment regimens in various settings. OBJECTIVES To determine whether ethnicity is associated with variance in patient management in Israel. METHODS Data were extracted from the electronic patient records of Clalit Health Services clinics in the Sharon Shomron region. The study group comprised all patients treated with war...

Objectives To 1) characterise older patients taking warfarin, 2) assess these patients' level of warfarin knowledge, and 3) describe their strengths and limitations in health literacy, and 4) explore relationships between participants' characteristics, warfarin knowledge and health literacy. Methods A warfarin knowledge questionnaire and Health Literacy Questionnaire (HLQ) were administered t...

BACKGROUND The importance of sharing a common mental model in communication prompted efforts to spread the use of the SBAR (Situation, Background, Assessment, and Recommendation) tool at OSF St. Joseph Medical Center, Bloomington, Illinois. CASE STUDY An elderly patient was on warfarin sodium (Coumadin) 2.5 mg daily. The nurse received a call from the lab regarding an elevated international n...

journal.publications.chestnet.org of our index cases over time (particularly the two individuals described in our report who were instrumental in our recognition of the local cluster and whose lives were devastated and shortened by this occupational lung disease) and our efforts to collate and interpret the available longitudinal surveillance data on workers have contributed more than a little ...

OBJECTIVES In the current study, we compared the effects of low- and high-flow anesthesia techniques on hemorheology and coagulation parameters in patients who received sevofluran. METHODS Forty patients classified as Risk Group I-II according to American Society of Anesthesiologists' (ASA) guidelines who were scheduled to undergo general anesthesia were randomly assigned to one of two groups...

A survey of physicians demonstrated that half had knowledge of the International Normalized Ratio (INR) but none used the value for monitoring their patients because it was not available from the Coagulation Laboratory. The Laboratory then provided the INR value at a physician's request. A six month review of prothrombin time (PT) results showed that only the physicians from the Cardiology Clin...

BACKGROUND Improved control of oral anticoagulation reduces adverse events. A program of quality measurement is needed for oral anticoagulation. The interval until the next test after an out-of-range International Normalized Ratio (INR) value (the "follow-up interval") could serve as a process of care measure. METHODS AND RESULTS We studied 104 451 patients cared for by 100 anticoagulation cl...

BACKGROUND Oral anticoagulant therapy (OAT) implies frequent blood checks and dose changes to prevent thromboembolic or hemorrhagic complications. This may interfere with patients' social and working circumstances in addition to the possible stress caused by the condition necessitating this treatment. We studied whether patient self-management could be a way to improve quality of life in these ...
