A Novel Isotropic Optical Fiber: Antimicrobial Effect of Blue Light on Drug Resistant Organisms.

Drug-resistant organisms (DROs) necessitate the development of new therapies. Antimicrobial blue light (ABL) is a promising option, utilizing photoexcitation of endogenous bacterial components to generate reactive oxygen species, leading to bacterial death. The aim of this study is to investigate the effects of a novel isotropic optical fiber under in-vitro conditions on multidrug-resistant gram-negative Pseudomonas aeruginosa (MDR-Pa) and methicillin-resistant Staphylococcus aureus (MRSA).

Pilot study on the in-vitro effect of radiation therapy on bending stiffness of intramedullary photodynamic implants.

Photodynamic implants are an increasingly popular minimally invasive option for the surgical treatment of metastatic bone disease. Following surgery, adjuvant radiation therapy (RT) is frequently administered to achieve better disease control and improve patient quality of life, but the role of RT in implant failures associated with photodynamic implants remains unclear. The aim of this study is to determine if the therapeutic RT range of 10-50 Gy affects the biomechanical properties of photodynamic implants.

Wound-Healing Effects of Common Antineoplastic Agents and Perioperative Considerations for the Orthopaedic Surgeon.

In oncologic patients, optimal postoperative wound healing is crucial for the maintenance of systemic therapies and improved survival. Although several risk factors for postoperative wound complications have been identified, the clinical effect of new antineoplastic agents on wound healing remains uncertain. The available literature on the effect of antineoplastic agents in wound healing is complex to analyze because of other confounding risk factors such as radiation therapy and certain patient-specific variables.

Phosphaturic mesenchymal tumor: management and outcomes of ten patients treated at a single institution.

Background: Phosphaturic mesenchymal tumor (PMT) is a rare tumor that causes tumor-induced osteomalacia. Patients present with non-specific symptoms secondary to renal phosphate wasting and decreased bone mineralization. We sought to assess: (1) What are the common presenting features, laboratory and imaging findings, histologic findings of phosphaturic mesenchymal tumors? (2) What are the available treatment strategies for phosphaturic mesenchymal tumors and their long-term outcomes in terms of local recurrence and symptom control after treatment?

Methods: We retrospectively identified patients with a histologic diagnosis of PMT located in the axial or appendicular skeleton, or surrounding soft tissues.

Reevaluation of the genus Cyclops Mller, 1776 (Cyclopoida: Cyclopidae) in the Laurentian Great Lakes basin: first report of the Palearctic species Cyclops divergens Lindberg, 1936 from Lake Erie and documentation of Cyclops sibiricus Lindberg, 1949 in the St. Marys River.

Large cyclopoid copepods of the genus Cyclops Mller, 1776 are seldom collected in the Laurentian Great Lakes, with only Cyclops scutifer Sars, 1863 and Cyclops strenuus Fischer, 1851 reported from the region. Rare reports of the species C. strenuus date back to 1972 within the Great Lakes basin.

Design of a novel multifunction decision support/alerting system for in-patient acute care, ICU and floor (AlertWatch AC).

Background: Multifunction surveillance alerting systems have been found to be beneficial for the operating room and labor and delivery. This paper describes a similar system developed for in-hospital acute care environments, AlertWatch Acute Care (AWAC).

Results: A decision support surveillance system has been developed which extracts comprehensive electronic health record (EHR) data including live data from physiologic monitors and ventilators and incorporates them into an integrated organ icon-based patient display.

Research in the retirement village community-The problems of recruiting a representative cohort of residents in Auckland, New Zealand.

Objectives: Retirement villages are semi-closed communities, access usually being gained via village managers. This paper explores issues recruiting a representative resident cohort, as background to a study of residents, to acquire sociodemographic, health and disability data and trial an intervention designed to improve outcomes.

Methods: We planned approaching all Auckland/Waitematā District villages and, via managers, contacting residents ('letter-drop'; 'door-knocks').

The Asian cyclopoid copepod Mesocyclops pehpeiensis reported from the western basin of Lake Erie.

The Asian cyclopoid copepod Mesocyclops pehpeiensis Hu, 1943 has been reported as an introduced species at several locations in the western hemisphere. In the United States, reports of this exotic species are restricted to localities in Louisiana, Mississippi, and Washington D.C.

First record of the Neotropical cladoceran in the Great Lakes basin.

The ctenopod has been reported primarily from the Neotropical region and occasionally from the southern United States. was collected in the Great Lakes basin (the Maumee River, Western Lake Erie, and Lake Michigan) in 2015 and 2018, far north from its previously known distribution. The occurrence of this southern species in the Maumee River and Great Lakes may be the result of an anthropogenic introduction, although a natural range expansion cannot be excluded.

Evolutionary responses to crude oil from the Deepwater Horizon oil spill by the copepod .

The BP Deepwater Horizon Oil Disaster was the most catastrophic offshore oil spill in U.S. history, yet we still have a poor understanding of how organisms could evolve in response to the toxic effects of crude oil.

Predictors of Long-term Opioid Use Following Lumbar Fusion Surgery.

Study Design: A population-based retrospective cohort study.

Objective: The aim of this study was to examine risk factors for long-term opioid use following lumbar spinal fusion surgery in a nationally representative cohort of commercially insured adults.

Summary Of Background Data: Opioid prescription rates for the management of low back pain have more than doubled in the US over the past decade.

Two new aromadendrane sesquiterpenes from the stem bark of Alafia multiflora.

Two new aromadendrane sesquiterpenoids (1β,4β,5β,6α,7α,11S)-aromadendr-9-en-13,14-dioic acid (1) and (1β,4β,5β,6α,7α,11S)-13-oxoaromadendr-9-en-14-oic acid (2) have been isolated from the stem bark of Alafia multiflora along with β-sitosterol and β-sitosterol glucoside. Their structures were established on the basis of spectroscopic analyses, including 1D and 2D NMR experiments (1H-1H COSY, NOESY, HSQC, HMBC). Compound 1 showed a weak growth inhibitory activity against the murine melanoma line B16F10 MTT.
