Medication For Opioid Use Disorder At Hospital Discharge Is Not Associated With Intravenous Antibiotic Completion In Post-Acute Care Facilities, Edward C Traver, Patrick R Ching, Shivakumar Narayanan

Open Access Publications

Background: People with opioid use disorder and severe infections may complete their prolonged courses of outpatient parenteral antimicrobial therapy at a post-acute care facility due to adherence and safety concerns. We hypothesized that treatment with medications for opioid use disorder, such as methadone and buprenorphine, would increase antibiotic completion in these facilities.

Methods: We performed a retrospective cohort study of people with opioid use disorder and severe infections who were discharged from the University of Maryland Medical Center to a post-acute care facility to complete intravenous antibiotic therapy. The primary outcome was completion of outpatient parenteral antimicrobial therapy. We compared …

Sglt2 Inhibitors Therapy Protects Glucotoxicity-Induced Β-Cell Failure In A Mouse Model Of Human Katp-Induced Diabetes Through Mitigation Of Oxidative And Er Stress, Zeenat A. Shyr, Zihan Yan, Alessandro Ustione, Erin M. Egan, Maria S. Remedi

Open Access Publications

Progressive loss of pancreatic β-cell functional mass and anti-diabetic drug responsivity are classic findings in diabetes, frequently attributed to compensatory insulin hypersecretion and β-cell exhaustion. However, loss of β-cell mass and identity still occurs in mouse models of human KATP-gain-of-function induced Neonatal Diabetes Mellitus (NDM), in the absence of insulin secretion. Here we studied the temporal progression and mechanisms underlying glucotoxicity-induced loss of functional β-cell mass in NDM mice, and the effects of sodium-glucose transporter 2 inhibitors (SGLT2i) therapy. Upon tamoxifen induction of transgene expression, NDM mice rapidly developed severe diabetes followed by an unexpected loss of insulin content, decreased …

Evaluation Of The Quality Changes Of Common Beans (Phaseolus Vulgaris L.) Varieties During Storage In Hermetic Polyethylene Bags, Micah Rambeka Momanyi

All Master’s Theses

Common beans (Phaseolus vulgaris L.) are extensively cultivated in sub-Saharan Africa as a cheap source of proteins, starch, dietary fiber, and excellent mineral salts and vitamins. However,beans are lost due to poor post-harvest handling and storage practices that provide insufficient protection against storage insect pests. Therefore, farmers are forced to apply insecticides more than once in a storage period to achieve protection. Excessive use of chemicals is not safe for health and is uneconomical. Hermetic techniques for storage have attracted increasing attention in recent years as chemical-free methods to preserve food grains and protect them against storage insect pests. Whereas …

Protocols Of Improvements For Pmma Denture Base Resin: An Overview, Nidal W. Elshereksi, Fathie A. Kundie, Andanastuti Muchtar, Che H. Azhari

Journal of Metals, Materials and Minerals

Polymethyl methacrylate (PMMA) is a polymer that is expansively employed in denture base construction due to its low cost, aesthetics, lightweight, reparability, and processability. Nevertheless, this material is not ideal to fulfill the mechanical and physical characteristics of dental restorations. Despite the popularity of the thermal polymerization method, the main shortcoming is the prolonged curing period. Thus, correctly selecting a polymerization cycle and post-polymerization treatment is needed to achieve promising outcomes. In autoclave polymerization, pressure plays a crucial function in accelerating the initial polymerization as well as decreasing the pores and remaining monomer level, thereby improving the flexural strength. Besides, …
