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.

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.

Neurologic Complications Associated With Burn Injury and Resuscitation.

Background: Treatment for large burn injuries relies on adequate fluid resuscitation secondary to the severe systemic inflammatory response. With improved critical care and better understanding of the complications of over and under resuscitation, morbidity and mortality rates are decreasing. Neurologic complications are not often considered as an over-resuscitation complication after burn injury but may be considered an additional form of compartment syndrome-intracranial compartment syndrome; however, it has not been evaluated for a possible threshold similar to the Ivy Index for abdominal compartment syndrome.

Factors Associated With Return to Work Following Laminoplasty for Degenerative Cervical Myelopathy.

Study Design: Retrospective cohort study.

Objective: To identify factors predictive of returning to work within 90 days of laminoplasty for degenerative cervical myelopathy (DCM).

Background: DCM is a debilitating condition resulting from spinal canal stenosis and spinal cord compression.

Anesthetic Management of Intracardiac Migration of Medical Devices.

The use of endovascular, percutaneous interventions to treat cardiac, arterial, and venous pathologies is becoming increasingly common in medical practice. While endovascular device placement typically carries a low risk, device migration remains a persistent problem with these procedures for which anesthesia providers must have a high index of suspicion. Anesthesia providers should be aware of the wide range of indications for such devices, potential migration locations, and hemodynamic consequences of both the inciting pathology and device migration so they can safely care for patients in these settings.

Consideration of Antifungal Coverage in Treating Infections Related to Delayed Esophageal Perforation from Anterior Cervical Spine Hardware.

(1) Background/Objectives: Delayed esophageal perforation following anterior cervical (spine) discectomy and fusion (ACDF) is rare but can lead to serious infectious complications. The treatment usually involves hardware explanation and prolonged intravenous antibiotics; however, there are scarce reports about the microbiology of these infections and corresponding targeted therapy. (2) Methods: Patients diagnosed or treated for delayed esophageal perforation after anterior cervical fusion between 2000-2020 at a tertiary medical center were studied.

Selective CO Reduction Electrocatalysis Using AgCu Nanoalloys Prepared by a "Host-Guest" Method.

Multimetallic nanoalloy catalysts have attracted considerable interest for enhancing the efficiency and selectivity of many electrochemically driven chemical processes. However, the preparation of homogeneous bimetallic alloy nanoparticles remains a challenge. Here, we present a room-temperature and scalable, host-guest approach for synthesis of dilute Cu in Ag alloy nanoparticles.

Open Versus Endoscopic Approach for Thoracic Disk Herniations: Equivalent Short-Term Outcomes With Significantly Different Costs.

Background And Objectives: Open thoracic diskectomy often requires significant bone resection and fusion, whereas an endoscopic thoracic diskectomy offers a less invasive alternative. Therefore, we sought to compare one-level open vs endoscopic thoracic diskectomy regarding (1) perioperative outcomes, (2) neurological recovery, and (3) total cost.

Methods: A single-center, retrospective, cohort study using prospectively collected data of patients undergoing one-level thoracic diskectomy was undertaken from 2018 to 2023.

Revisiting the Posterior Approach for Cervical Radiculopathy Utilizing Endoscopic Techniques: A Favorable Short-Term Outcome and Cost Comparison With Anterior Cervical Discectomy and Fusion.

Background: Cervical radiculopathy is a spine ailment frequently requiring surgical decompression via anterior cervical discectomy and fusion (ACDF) or posterior foraminotomy/discectomy. While endoscopic posterior foraminotomy/discectomy is gaining popularity, its financial impact remains understudied despite equivalent randomized long-term outcomes to ACDF. In a cohort of patients undergoing ACDF vs endoscopic posterior cervical foraminotomy/discectomy, we sought to compare the total cost of the surgical episode while confirming an equivalent safety profile and perioperative outcomes.

Clinical Effectiveness of Anterior Cervical Discectomy and Fusion Using Tritanium C Anterior Cervical Cage vs. PEEK Cage.

Introduction: Anterior cervical discectomy and fusion (ACDF) has proven to be a clinically efficient and cost-effective method for treating patients with degenerative cervical spine conditions. New intervertebral implant products are being developed to improve fusion and stability while decreasing complications. This study assesses the effectiveness of Tritanium C (Tri-C) Anterior Cervical Cage (Stryker) in the treatment of degenerative disk disease (DDD) of the cervical spine compared with polyetheretherketone (PEEK) cages.

Sex differences in sympathetic transduction in black and white adults: implications for racial disparities in hypertension and cardiovascular disease risk.

The prevalence of hypertension in non-Hispanic black (BL) individuals is the greatest of any racial/ethnic group. Whereas women generally display lower rates of hypertension than men of the same background, BL women display a similar if not greater burden of hypertension compared with BL men. The risk for cardiovascular disease and related events is also highest in BL individuals.

Obstacles to receiving postoperative radiation therapy following separation surgery for metastatic spine disease.

Objective: Obtaining timely postoperative radiotherapy (RT) following separation surgery is critical to avoid local recurrence of disease yet can be a challenge due to scheduling conflicts, insurance denials, and travel arrangements. In patients undergoing metastatic spine surgery for spinal cord compression, the authors sought to: 1) report the rate of postoperative RT, 2) describe reasons for patients not receiving postoperative RT, and 3) investigate factors that may predict whether a patient receives postoperative RT.

Methods: A single-center retrospective case series was undertaken of all patients who underwent metastatic spine surgery for extradural disease between January 2010 and January 2021.

Comparing the Upper Instrumented Vertebrae Tilt Angle vs Screw Angle in the Development of Proximal Junction Kyphosis After Adult Spinal Deformity Surgery: Which Matters More?

Background: We sought to determine which aspect of the upper instrumented vertebrae (UIV)-tilt angle or screw angle-was more strongly associated with: (1) proximal junctional kyphosis/failure (PJK/F), (2) other mechanical complications and reoperations, and (3) patient-reported outcome measures (PROMs).

Methods: A single-institution, retrospective cohort study was undertaken for patients undergoing adult spinal deformity (ASD) surgery from 2011 to 2017. Only patients with UIV at T7 or below were included.

Stopping at C2 Versus C3/4 in Elective Posterior Cervical Decompression and Fusion: A 5-Year Follow-up Study.

Study Design: This is a retrospective cohort study.

Objective: In patients undergoing elective posterior cervical laminectomy and fusion (PCLF) with a minimum of 5-year follow-up, we sought to compare reoperation rates between patients with an upper instrumented vertebra (UIV) of C2 versus C3/4.

Summary Of Background Data: The long-term outcomes of choosing between C2 versus C3/4 as the UIV in PCLF remain unclear.

"We restrict certain things": a cross-sectional study of health provider adherence to WHO's recommendation for intrapartum oral intake of fluid and food in Greater Accra, Ghana.

Background: Since 2018, WHO recommends oral fluid and food intake for low-risk women during labor to enhance positive childbirth experience and respect for women's preferences. This study investigated the current practices related to intrapartum oral intake among maternity care providers and women in public health facilities in Greater Accra, Ghana, and explored barriers and opportunities for adherence to the WHO guidance.

Does Timing of Radiation Therapy Impact Wound Healing in Patients Undergoing Metastatic Spine Surgery?

Introduction: The impact of radiation on wound healing after metastatic spine surgery remains an active area of research. In patients undergoing metastatic spine surgery, we sought to (1) assess the relationship between preoperative and/or postoperative radiation on wound complications, and (2) evaluate the relationship between the timing of postoperative radiation and wound complications.

Methods: A single-center, retrospective, cohort study of patients undergoing metastatic spine surgery was conducted from 2010 to 2021.

Safety of early discharge after elective lumbar spine surgery with subfascial drains and association with significant reduction in length of stay.

Objective: After lumbar spine surgery, postoperative drain removal often delays discharge. Whether inpatient drain removal reduces the risk of surgical site infection (SSI) or hematoma remains controversial. Therefore, in patients undergoing elective lumbar spine surgery, the authors sought to determine the impact of inpatient versus outpatient drain removal on the following variables: 1) length of hospital stay (LOS), and 2) postoperative complications.

Earlier Radiation Is Associated with Improved 1-Year Survival After Metastatic Spine Tumor Surgery.

Objective: In patients undergoing metastatic spine surgery, we sought to 1) report time to postoperative radiation therapy (RT), 2) describe the predictive factors of time to postoperative RT, and 3) determine if earlier postoperative RT is associated with improved local recurrence (LR) and overall survival (OS).

Methods: A single-center retrospective cohort study was undertaken of all patients undergoing spine surgery for extradural metastatic disease and receiving RT within 3 months postoperatively between January 2010 and January 2021. Time to postoperative RT was dichotomized at <1 month versus 1-3 months.
