Geomorphic Landforms and Plant Community Structure and Dominance In the Central Desert Region of Baja California, México
submitted by 7 minutes ago - Topic: Biology
Geomorphic gradients of landforms and associated soil catenas in the Central Desert region of Baja California produce complex but repeatable patterns of plant community distribution and a diversity of plant functional groups distributed unequally over the gradient. We measured plant diversity and made three assessments of plant dominance in six plant communities associated with a gradient of ge...



Factors Determining the Establishment of Plant Zonation In A Southern Californian Riparian Woodland
submitted by 8 minutes ago - Topic: Biology
This paper describes plant zonation in a southern California riparian woodland and identifies the factors responsible for the zonation. Of the 25 common trees and shrubs in the Tijuana River Valley, three were numerically dominant: Baccharis salicifolia (Ruiz & Pav.) Pers., Salix lasiolepis Benth., and Salix gooddingii C. R. Ball, here referred to as BASA, SALA, and SAGO, respectively. Adul...

Inferior vena cava filter insertion and retrieval patterns in a tertiary referral centre in Ireland
submitted by 8 minutes ago - Topic: Health
Inferior vena cava (IVC) filters are widely used in clinical practice to prevent large, clinically significant pulmonary emboli. Modern filters are designed to be retrievable within a specific time window; however, many become lost to follow-up. To examine the insertion and retrieval patterns of IVC filters in a tertiary referral teaching hospital in Ireland. A retrospective review of all IVC f...

Efficacy of uvulopalatopharyngoplasty combined with oral appliance in treatment of obstructive sleep apnea–hypopnea syndrome
submitted by 8 minutes ago - Topic: Health
This study aimed to investigate the efficacy of UPPP combined with an oral appliance (OA) in the treatment of obstructive sleep apnea–hypopnea syndrome (OSAHS). Forty patients diagnosed with severe OSAHS were randomly divided into two groups: 20 patients in the pure surgery group treated by uvulopalatopharyngoplasty (UPPP) surgery and the remaining 20 patients in the combined treatment group ...

Allergy in Irish adults: a survey of referrals and outcomes at a major centre
submitted by 8 minutes ago - Topic: Health
There is an increasing demand for specialist public allergy services across Ireland. Little data exist on the patterns of allergic disease in Irish adults. The limited resources available require innovative strategies to ensure quality care delivery. This study aimed to review the types of allergy referrals and diagnostic outcomes at a major Irish centre, and to establish an efficient method of...



Patient level costing in Ireland: process, challenges and opportunities
submitted by 8 minutes ago - Topic: Health
In 2013, the Department of Health released their policy paper on hospital financing entitled Money Follows the Patient. A fundamental building block for the proposed financing model is patient level costing. This paper outlines the patient level costing process, identifies the opportunities and considers the challenges associated with the process in the Irish hospital setting. involved a review...

A Comparison of In-person, Telephone, and Secure Messaging for Type 2 Diabetes Self-Management Support
submitted by 12 minutes ago - Topic: Biology
Ongoing interaction between diabetes educators and patients is necessary for making and sustaining behavior changes essential for glycemic control and subsequently reducing the complications of diabetes. The purpose of this study was to determine the feasibility of diabetes self-management support (DSMS) delivered via telephone or secure message and to compare clinical outcomes (A1C, LDL), beha...


Contributions of Second Opinions, Outcome Forecasts, and Testimonials to Patient Decisions about Knee Replacement Surgery
submitted by 15 minutes ago - Topic: Health
Decision aids are now a well-established means of supporting patients in their medical decision making. The widespread use of decision aids invites questions about how their components contribute to patient decisions. The objective of this study was to measure the importance of second opinions, patient-specific outcome forecasts, and patient testimonials relative to patient clinical and socioec...

A Balance Beam Aid for Instruction in Clinical Diagnostic Reasoning
submitted by 15 minutes ago - Topic: Health
We describe a balance beam aid for instruction in diagnosis (BBAID) and demonstrate its potential use in supplementing the training of medical students to diagnose acute chest pain. We suggest the BBAID helps students understand the process of diagnosis because the impact of tokens (weights and helium balloons) attached to a beam at different distances from the fulcrum is analogous to the impac...


The Balance Beam Metaphor: A Perspective on Clinical Diagnosis
submitted by 15 minutes ago - Topic: Health
Understanding the impact of clinical findings in discriminating between possible causes of a patient’s presentation is essential in clinical judgment. A balance beam is a natural physical analogue that can accurately represent the combination of several pieces of evidence with varying ability to discriminate between disease hypotheses. Calculation of Bayes’ theorem using log(posteri...

The Influence of Disease Risk on the Optimal Time Interval between Screens for the Early Detection of Cancer: A Mathematical Approach
submitted by 15 minutes ago - Topic: Health
The intervals between screens for the early detection of diseases such as breast and colon cancer suggested by screening guidelines are typically based on the average population risk of disease. With the emergence of ever more biomarkers for cancer risk prediction and the development of personalized medicine, there is a need for risk-specific screening intervals. The interval between successive...


Comparison of 4 Pediatric Health-Related Quality-of-Life Instruments: A Study on a Medicaid Population
submitted by 15 minutes ago - Topic: Health
Few studies have compared multiple health-related quality-of-life (HRQOL) instruments simultaneously for pediatric populations. This study aimed to test psychometric properties of 4 legacy pediatric HRQOL instruments: the Child Health and Illness Profile (CHIP), the KIDSCREEN-52, the KINDL, and the Pediatric Quality of Life Inventory (PedsQL). Methods. This study used data from 908 parents whos...

Stable isotope mass balance of the Laurentian Great Lakes
submitted by 15 minutes ago - Topic: Geography
We investigate the physical limnology of the Laurentian Great Lakes of North America using a new dataset of 18O/16O and 2H/1H ratios from over 500 water samples collected at multiple depths from 75 stations during spring and summer of 2007. δ 18O and δ 2H values of each lake plot in distinct clusters along a trend parallel to, but offset from, the Global Meteoric Water Line, reflecting the...

Sediment resuspension in the Lake Erie nearshore
submitted by 15 minutes ago - Topic: Geography
A decline in water quality in Lake Erie during the last decade, despite increased efforts to limit nutrient loading, may be better understood by examining internal processes in the lake. We employed 7Be, 210Pb and 137Cs measurements of suspended matter in tributaries, in the lake water column, in atmospheric precipitation, in sediment traps and in bottom sediments collected in June and august/S...

Determination of optimum time for intravenous cannulation after induction with sevoflurane and nitrous oxide in children premedicated with midazolam
submitted by 16 minutes ago - Topic: Health
It has been shown that early placement of an intravenous line in children administered sevoflurane anesthesia increased the incidence of laryngospasm and movement. However, the optimal time for safe cannulation after the loss of the eyelash reflex during the administration of sevoflurane and nitrous oxide is not known. The aim of the study was to determine the optimum time for intravenous cannu...
