Summary

This trial found that blue light exposure was able to modulate the host response to injury and critical illness, potentially improving outcome.

Who is the study for?
This trial is for adults over 18 who are undergoing surgery for appendicitis or diverticulitis, or receiving treatment for pneumonia. It's not suitable for individuals with traumatic brain injury, blindness, or those who have weakened immune systems.
What is being tested?
The study tests the effects of blue light exposure on patients' inflammatory responses after surgeries like appendectomy and colon resection, and during pneumonia treatment. The control group doesn't receive blue light to compare outcomes.
What are the potential side effects?
Since this trial involves exposure to blue light rather than medication, traditional side effects may not apply. However, potential discomforts could include eye strain or headache from the light.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
All Cohorts: change in serum concentrations of circulating inflammatory mediators in the blood
All groups: change in expression of circadian proteins in circulating immune cells
Pneumonia: change in bronchoalveolar lavage (BAL) bacteria concentration
Secondary study objectives
All Cohorts: change in organ dysfunction
Appendicitis and Diverticulitis: intraabdominal abscess formation
Pneumonia: need for and duration of mechanical ventilation

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

Trial Design

8Treatment groups
Experimental Treatment
Active Control
Group I: Pneumonia: Blue LightExperimental Treatment1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of bright (1700 lux) blue (peak 442 nm) enriched light for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the blue-enriched light is turned off, and additional blue wavelength light removed with an amber filter.
Group II: Necrotizing Soft Tissue Infection: Blue LightExperimental Treatment1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of bright (1700 lux) blue (peak 442 nm) enriched light for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the blue-enriched light is turned off, and additional blue wavelength light removed with an amber filter.
Group III: Intraabdominal infection: Blue LightExperimental Treatment1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of bright (1700 lux) blue (peak 442 nm) enriched light for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the blue-enriched light is turned off, and additional blue wavelength light removed with an amber filter.
Group IV: Infected Joint: Blue LightExperimental Treatment1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of bright (1700 lux) blue (peak 442 nm) enriched light for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the blue-enriched light is turned off, and additional blue wavelength light removed with an amber filter.
Group V: Necrotizing Soft Tissue Infection: Ambient LightActive Control1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of the standard white fluorescent ambient light of the hospital for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the ambient white lights are turned off.
Group VI: Intraabdominal infection: Ambient LightActive Control1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of the standard white fluorescent ambient light of the hospital for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the ambient white lights are turned off.
Group VII: Infected Joint: Ambient LightActive Control1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of the standard white fluorescent ambient light of the hospital for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the ambient white lights are turned off.
Group VIII: Pneumonia: Ambient LightActive Control1 Intervention
a 12 hours:12 hours light:dark photoperiod cycle of the standard white fluorescent ambient light of the hospital for a total of 3 days after the initial diagnosis and informed consent. The photoperiod is 12 hours: 0800 to 2000. At the transition from light to dark (2000), the ambient white lights are turned off.
