Telehealth and Type 2 Diabetes Management

Ikpeama, Blessing Nneoma 01 January 2019 (has links)
The use of telehealth in healthcare has grown in recent years; however, little is known about the effectiveness of this delivery method in the management of Type 2 diabetes mellitus (T2DM). Guided by the chronic care model and telehealth in chronic disease model, the purpose of this systematic literature review was to explore evidence related to lowering hemoglobin A1c levels and managing T2DM using telehealth in the outpatient setting. The practice-focused questions explored telehealth interventions used in T2DM management and their effectiveness. The Joanna Briggs Institute (JBI) method for conducting systematic literature reviews was the process, and data were compiled using the PRISMA evidence-based minimum set for reporting. Eighteen studies met the inclusion criteria for this project. Data were extracted, analyzed, and synthesized using JBI tools for data extraction and critical appraisal. Article appraisals revealed numerous telehealth interventions for management of T2DM including telephone, Internet-based, clinical video, remote monitoring, and smart phones/applications. Overall, telehealth interventions showed statistically significant improvement in the hemoglobin A1c levels of participants compared to traditional outpatient care. Success of the interventions is associated with components of evidenced-based diabetes management such as education, self-management, support, and feedback loop. The implications of this project for positive social change include the integration of telehealth interventions in the outpatient setting to manage T2DM with enhanced access to care, reduction in health disparities, and improved health outcomes for society.

Is Vitamin A Supplementation Associated With Anemia in Children Under 5 Years of Age in Peru: Secondary Analysis of the “Demographic Health Survey” 2015-2018?

Ribaudo, Isabella, Aramburú-Duclos, Camila B., Blitchtein, Dora 01 January 2021 (has links)
Vitamin A deficiency (VAD) affects 12% of Peruvians under 5 years of age. Recent studies have shown an association with hematopoiesis and iron metabolism. In Peru, 3-quarters of a million children have anemia. We aimed to identify an association between Vitamin A supplementation (VAS) and anemia in children under 5 years of age. A cross-sectional secondary analytical study from the Peruvian Demographic Survey and Family Health (DHS) was conducted. The primary outcome, anemia, was measured through hemoglobin concentration and adjusted by altitude. The DHS interviewer ensured the participant’s VAS in the last 6 months through a structural healthcare card. The association was statistically significant using crude regression but disappeared when adjusted per socioeconomic level and gender. VAS was not significantly associated with a lower prevalence of anemia. Further studies are required to help identify the association between VAS and anemia. / Revisión por pares

Effects of washing units of canine red blood cells on storage lesions

Coll, Ashley 30 April 2021 (has links) (PDF)
In humans, washing stored blood products prior to transfusion reduces storage lesions and the potential for transfusion reaction, but the effectiveness of washing units of canine whole blood is unknown. The objective of this study was to determine if a manual method of washing of stored whole blood units reduced storage lesions without adversely affecting erythrocytes. Units of canine whole blood were stored for 28 days and manually washed three times with sterile .9% NaCl. Following the first wash, there was a decrease in serum potassium (P<.0001), lactate (P<.0001), pH (P=.0110), pCO2 (P<.0001), TCO2 (P<.0001), arachidonic acid (P<.0001), and thromboxane B2 (P=.0417), and increases in iCa (P=.0494), iMg (P=.0024), MCV (P<.0001), MCHC (P=.0093), RDW (P=.0009), hemoglobin (P=.0011), and MCF (P=.0006). No bacterial growth was identified on the post-transfusion samples. Manual washing of stored blood significantly reduces storage lesions after a single wash and additional washing may cause in vitro hemolysis.

Changes in hemoglobin during metamorphosis of the Salamander

Mecham, Harvey Dee 01 August 1967 (has links)
Analysis of hemogobins were conducted on animals of the species Ambystoma tigrinum. Separation of hemoglobin types was performed with a Carboxy-methyl-cellulose column (6 X 50 mm.) and pH gradient (pH 6 thru 8) of .01 M phosphate buffer. The hemoglobins in the effluent were detected and analysed with a micro-flow cell in a Beck-man DB-G spectrophotometer attached to a Photovolt Varicord 43 recorder. Two major components of hemoglobin were observed: larval and adult. These two components varied in concentration with the stage of development of the individual. In addition, it was noted that minor peaks ansd shoulders appeared on each peak wich were consistant and characteristic for each major hemoglobin type.

The purpose of this work was evolution of influence, of different methodological approaches to of glycated hemoglobin results. Samples of 100 patients with Diabetes Mellitus was analyzed for glucose and HbA1c. There was shown correlation between average concentration glucose‘s during three months coefficient. HbA1c was analyzed using three analytical systems of Roche-Hitachi 917, Bayer-Advia1650 and Dade Behring-Dimension RxL standardized according different standardization recommendations: International Federation of Clinical Chemistry and Laboratory Medicine (IFCC), Diabetes Control and Complications Trial (DCCT), National Glycohemoglobin Standardization Program (NGSP). Roche-Hitachi 917 results standardized according IFCC recommendations were chosen as reference. Correlation and differences between analytical systems were as follows. Roche-Hitachi 917 (IFCC) – Bayer-Advia1650 (NGSP): r = 1.017 [0.883 to 1.188]; y = 3.068 [1.894 to 4.142]; n = 52; p = 0.0000001.
