Colorimetric Determination of Dissolved Oxygen: Assessment of Methodological Influences on Iodine Spectra, Isosbestic Point, Precision and Accuracy.

The colorimetric method for determining dissolved oxygen concentrations in freshwater and seawater samples essentially relies on measuring the absorbance of released I and I in a mixed form. While this approach is relatively quick and convenient, it is susceptible to significant temperature effects during analysis, irrespective of field temperatures. Additionally, the influences of spectrophotometric absorbance wavelengths and iodine concentrations on oxygen concentration determinations are ambiguous.

Should We Operate on Octogenarians with Cervical Myelopathy or Radiculopathy?

Study Design: Retrospective Cohort.

Objective: Investigate the disparities between octogenarians and non-octogenarians undergoing cervical spine surgery regarding perioperative, and postoperative outcomes.

Summary Of Background Data: As the population ages, the demand for elective cervical spine surgery among older, more active adults increases.

The 2024 American Orthopaedic Association-Japanese Orthopaedic Association Traveling Fellowship.

In 1992, the American Orthopaedic Association-Japanese Orthopaedic Association (AOA-JOA) Traveling Fellowship was created to develop and enhance collaboration between the Japanese and American orthopaedic communities. The fellowship is geared to early-career surgeons and fosters clinical and cultural exchange between members of the 2 countries. In 2024, the fellows hailed from around the United States: Kelly K.

Smoking Does Not Negatively Impact Outcomes Following Cervical Laminoplasty: A Quality Outcomes Database Study.

Study Design: Retrospective cohort study.

Objective: To assess the impact of smoking on outcomes following elective cervical laminoplasty for degenerative cervical myelopathy (DCM).

Summary Of Background Data: The detrimental effect of cigarette smoking on cervical spinal fusion surgery outcomes is well documented.
