The effect of photobiomodulation on histamine and Mucuna pruriens-induced pruritus, hyperknesis and alloknesis in healthy volunteers: A double-blind, randomized, sham-controlled study. PLoS One 2024; 19:e0307034. [PMID: 39024251 PMCID: PMC11257285 DOI: 10.1371/journal.pone.0307034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 06/26/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND Photobiomodulation, also referred to as Low-Level Light Therapy (LLLT), has emerged as a promising intervention for pruritus, a prevalent and often distressing symptom. OBJECTIVES This study investigated the efficacy of low-level light therapy (LLLT) in alleviating pruritus, hyperknesis, and alloknesis induced by histamine and Mucuna pruriens. METHODS In a double-blind, randomized, sham-controlled trial with a split-body design, healthy volunteers underwent 6 minutes of LLLT and sham treatments in separate upper back quadrants. The histamine model was applied to the upper quadrants, and Mucuna pruriens to the lower quadrants. Pruritus intensity, alloknesis, hyperknesis, flare area, and skin temperature were measured pre and post treatment. RESULTS Seventeen individuals (eight females, nine males) participated in the study. In the histamine model, LLLT notably reduced itch intensity (difference = 13.9 (95% CI: 10.5 - 17.4), p = 0.001), alloknesis (difference = 0.80 (95% CI: 0.58-1.02), p = 0.001), and hyperknesis (difference = 0.48 (95% CI: 0.09-0.86), p = 0.01). Skin temperature changes were not significantly different between the two groups (difference = -2.0 (95% CI: -6.7-2.6), p = 0.37). For the Mucuna pruriens model, no significant differences were observed in any measures, including itch intensity (difference = 0.8 (95% CI: -2.3 - 3.8), p = 0.61) hyperknesis (difference = 0.08 (95% CI: -0.06-0.33), p = 0.16) and alloknesis (difference = 0. 0.09 (95% CI: -0.08-0.256), p = 0.27). CONCLUSIONS LLLT effectively reduced histamine-induced pruritus, alloknesis, and hyperknesis; however, LLLT was ineffective against Mucuna pruriens-induced pruritus. Further investigations are required to determine LLLT's effectiveness of LLLT in various pruritus models.

Abstract
PURPOSE To identify pharmacological and nonpharmacological interventions adopted for pain relief in the postoperative period of coronary artery bypass graft surgery. DESIGN Integrative review. METHODS Studies published in English, Spanish, and Portuguese from January 2010 to December 2019 in Cumulative Index to Nursing and Allied Health Literature (CINAHL), Latin American and Caribbean Literature on Health Science, PubMed, and Web of Science. Two hundred studies were identified and eleven were included. Methodological analysis was performed using the Medical Education Research Study Quality Instrument. FINDINGS The studies found were organized into three thematic categories: pharmacological interventions (methadone, morphine, lidocaine gel, remifentanil, sufentanil, and nefopam), nonpharmacological interventions (low-level laser therapy, light-emitting diode, Class IV laser, and transcutaneous nerve stimulation) and anesthetic techniques (dexmedetomidine, ultrasound-guided pectoral nerve block, high thoracic epidural analgesia, and perioperative parasternal block with levobupivacaine). CONCLUSIONS A greater tendency to use drug strategies for postoperative pain relief was identified. The drugs used demonstrated efficacy and safety in the treatment of pain, with the exception of nefopam, which showed little benefit in this population. Nonpharmacological interventions, used as adjuvants to drug treatment, were shown to be safe, effective, and well tolerated by the patients.

Abstract
Research is emerging on the use of Photobiomodulation therapy (PBMT) and its potential for augmenting human performance, however, relatively little research exists utilizing full-body administration methods. As such, further research supporting the efficacy of whole-body applications of PBMT for behavioral and physiological modifications in applicable, real-world settings are warranted. The purpose of this analysis was to observe cardiorespiratory and sleep patterns surrounding the use of full-body PBMT in an elite cohort of female soccer players. Members of a women’s soccer team in a “Power 5 conference” of the National Collegiate Athletic Association (NCAA) were observed across one competitive season while wearing an OURA Ring nightly and a global positioning system (GPS) sensor during training. Within-subject comparisons of cardiorespiratory physiology, sleep duration, and sleep composition were evaluated the night before and after PBMT sessions completed as a standard of care for team recovery. Compared to pre-intervention, mean heart rate (HR) was significantly lower the night after a PBMT session (p = 0.0055). Sleep durations were also reduced following PBMT, with total sleep time (TST) averaging 40 min less the night after a session (p = 0.0006), as well as significant reductions in light sleep (p = 0.0307) and rapid eye movement (REM) sleep durations (p = 0.0019). Sleep durations were still lower following PBMT, even when controlling for daily and accumulated training loads. Enhanced cardiorespiratory indicators of recovery following PBMT, despite significant reductions in sleep duration, suggest that it may be an effective modality for maintaining adequate recovery from the high stress loads experienced by elite athletes.

Abstract
OBJECTIVE The objective of this review is to evaluate the effect of low-level laser therapy, used alone or in combination with conventional therapies, on wound healing and pain reduction in patients with median sternotomy. INTRODUCTION In the previous two decades, the incidence of postsurgical complications following median sternotomy has remained reasonably unchanged. Owing to the shortcomings of conventional therapies in wound healing, alternative solutions are sought. Photobiomodulation with low-level laser therapy has become a preferred therapy for augmenting tissue repair and stimulating immediate analgesia by releasing local neurotransmitters and endorphins, or through anti-inflammatory effects. INCLUSION CRITERIA This review will include only randomized controlled trials that studied the effects of low-level laser therapy used as a monotherapy or in combination with other conventional therapies in promoting wound healing and reducing pain in adult patients with median sternotomy. Comparators may include other forms of photobiomodulation therapy/phototherapy, other conventional therapies, control, or placebo/sham interventions. METHODS Cochrane Central Register of Controlled Trials, MEDLINE (PubMed), CINAHL (EBSCO), AMED (EBSCO), Physiotherapy Evidence Database (PEDro), and Scopus will be searched from database inception to the present date. Two reviewers will independently screen, extract data, and examine methodological quality of the eligible studies using the JBI critical appraisal checklist for randomized controlled trials. A meta-analysis will be done if adequate data with homogeneous population, interventions, and outcomes are available. The overall level of evidence will be synthesized using the Grading of Recommendations, Assessment, Development and Evaluation criteria. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42020203011.

Abstract
Simple Summary Increasing societal and customer pressure to provide animals with ‘a life worth living’ continues to apply pressure on industry to alleviate pain associated with husbandry practices, injury and illness. Although a number of analgesic solutions are now available for sheep, providing some amelioration of the acute pain responses, this review has highlighted a number of potential areas for further research. Abstract Increasing societal and customer pressure to provide animals with ‘a life worth living’ continues to apply pressure on livestock production industries to alleviate pain associated with husbandry practices, injury and illness. Over the past 15–20 years, there has been considerable research effort to understand and develop mitigation strategies for painful husbandry procedures in sheep, leading to the successful launch of analgesic approaches specific to sheep in a number of countries. However, even with multi-modal approaches to analgesia, using both local anaesthetic and non-steroidal anti-inflammatory drugs (NSAID), pain is not obliterated, and the challenge of pain mitigation and phasing out of painful husbandry practices remains. It is timely to review and reflect on progress to date in order to strategically focus on the most important challenges, and the avenues which offer the greatest potential to be incorporated into industry practice in a process of continuous improvement. A structured, systematic literature search was carried out, incorporating peer-reviewed scientific literature in the period 2000–2019. An enormous volume of research is underway, testament to the fact that we have not solved the pain and analgesia challenge for any species, including our own. This review has highlighted a number of potential areas for further research.

Abstract
With the development of nanometer semiconductor laser technology, due to the wide range of photobiological regulation and non-invasive advantages, it is widely used in clinical research, including reducing pain, accelerating wound healing, nerve injury repair and regeneration. Increase tissue blood flow, improve anxiety and depression, and treat Parkinson's and retinal diseases. However, in many studies, the role of photobiological regulation is still controversial. There are two main problems, one is that the mechanism of photo biological regulation is not fully understood, and the other is that the specific parameters are not uniform in different treatments, such as wavelength density, power density, pulse, treatment timing, and number of treatments. In this paper, through the second question, the parameters of low-energy near-infrared light (810 nm semiconductor laser) in the treatment of fundus diseases are the main research objects. Based on understanding the parameters of low-energy lasers, cyan blue is irradiated with different energy near-infrared light. Data analysis of the actual energy obtained after the retina of the rabbit and observation and research on the cell morphology of each layer of the retina, to obtain relatively safe treatment parameters for the retina, provide theoretical data for near-infrared light in the treatment of clinical fundus disease, and make it safer to use in clinical treatment.

Abstract
Although coronary artery bypass graft (CABG) surgery is one of the most worldwide commonly performed cardiac surgeries to enhance myocardial perfusion in high-grade myocardial occlusion, it remains a high-risk procedure. Photobiomodulation (PBM) is one of the methods which have been shown to have positive effects on the healing process after CABG and postoperative complications. The aim of this study was to evaluate the efficacy of PBM in patients who underwent a coronary artery bypass graft (CABG). Ths study was conducted with 192 volunteers who electively submitted to CABG. The volunteers were randomly allocated into two groups: laser-treated (transdermal: 980 nm, 200 mW, continuous, average energy fluency of 6 J/cm2 and intravenous: 405 nm, 1.5 mW, continuous for 30 min) and standard treatment and control group (standard treatment only). Intravenous laser was illuminated the day before the surgery, immediately after transferring the patient to CCU post-operation and IV laser in addition to transdermal laser was applied every day after surgery for 6 days. A total of 170 out of 192 participants completed the study, 82 (48.2%) in the PBM group and 88 (51.8%) in the control group. Level of LDH and CPK was significantly lower in the PBM group (P < 0.05) in the 4th day postoperatively. The PBM group also showed significantly lower post-surgery complications, including pericardial effusion, ejection fraction, pathologic ST changes, pathologic Q, rehospitalization, heart failure, and mediastinitis (P < 0.05). Likewise, the VAS pain score after surgery was significantly lower in patients in the laser group (P < 0.05). PBM seems a promising, safe, cost-benefit therapeutic modality to reduce postoperative complications of CABG. Trial registration number: IRCT2016052926069N4 .

Abstract
Photobiomodulation, otherwise known as low-level laser (or light) therapy, is an emerging modality for the management of hair loss. Several randomized trials have demonstrated that it is safe and potentially effective on its own or in combination with standard therapies. These devices come in many forms including wearable caps or helmets that afford hands-free and discreet use. Models with light-emitting diodes (LEDs) are less expensive compared to laser-based devices and do not require laser safety considerations, thus facilitating ease of home use. Limitations include cost of the unit, risk of information bias, and lack of standardized protocols. Finally, as with any hair loss treatment, patients' expectations with regards to therapeutic outcomes must be managed.

Abstract
Introduction Several clinical trials have demonstrated that low-level light therapy (LLLT), a method of photobiomodulation, is an effective analgetic treatment. However, the mechanism of action has not yet been finally clarified. In particular, unanswered questions include whether it only affects peripheral or whether it also affects the spinal or supraspinal level. This study aimed to evaluate the effect of low-level light therapy on primary and secondary hyperalgesia in a human pain model. Methods This study was planned as a randomized, sham-controlled, and double-blinded trial with repeated measures within subject design. Capsaicin was applied on both forearms of ten healthy volunteers to induce peripheral and central sensitization. One forearm was treated with low-level light therapy; the other served as sham control. Results Low-level light therapy significantly increased the mechanical pain threshold, heat pain threshold, and decreased pain intensity. Conclusions Our data indicate that low-level light therapy is effective at reducing the heat and mechanical pain threshold in a human pain model, pointing to a significant modulating effect on peripheral and central sensitization. These effects—especially in the absence of reported side effects—make low-level light therapy a promising tool in pain management. The application of low-level light therapy to treat chronic pain should be considered for further clinical trials.

Abstract
Photobiomodulation (PBM) is a therapy suggested for the treatment of pain and inflammation. Different mechanisms have been proposed to explain the analgesic and inflammatory effects of photobiomodulation, but there are still gaps on the mechanisms underlying. The objective was to investigate the analgesic and anti-inflammatory effect of red LED, as well as to investigate the possible mechanism of action in acute nociception models. Radiation was applied with red LED (660 nm, 215 mW, 84.64 mW/cm2, 2.531 J/cm2 (30s); 5.07 J/cm2 (60s) 7.61 J/cm2 (90s) and 10.15 J/cm2 (120 s)). The red LED applied 60 s before the experiments, promoted reduction of the nociceptive neurogenic (1st phase) and inflammatory pain (2nd phase) induced by intraplantar (i.pl.) injection of formalin. This effect duration in the second phase was 180 min after pretreatment of the LED. Red LED also reduced nociception induced by intraperitoneal injection of acetic acid. Furthermore, red LED prevented nociception induced by i.pl. injection of cinnamaldehyde, capsaicin, menthol and acidified saline. It was demonstrate the involvement of glutamatergic system with the reduction the nociception induced by glutamate. The red LED was able to prevent nociception induced by intracellular signaling cascades activators, phorbol 12-myristate 13-acetate (PMA), bradykinin, forskolin and prostaglandin. In addition, red LED, respectively, from 30 to 90s demonstrated an antiedematogenic effect on ear edema and reduction the migration of inflammatory cells induced by single application of croton oil. Thus, the new findings in this study support some underlying mechanism by which red LED phototherapy reduces acute pain. However, need further clarification regarding analgesic and anti-inflammatory effect of the photobiomodulation in preclinical studies.

Abstract
Photobiomodulation (PBM) is a treatment method based on research findings showing that irradiation with certain wavelengths of red or near-infrared light has been shown to produce a range of physiological effects in cells, tissues, animals and humans. Scientific research into PBM was initially started in the late 1960s by utilizing the newly invented (1960) lasers, and the therapy rapidly became known as "low-level laser therapy". It was mainly used for wound healing and reduction of pain and inflammation. Despite other light sources being available during the first 40 years of PBM research, lasers remained by far the most commonly employed device, and in fact, some authors insisted that lasers were essential to the therapeutic benefit. Collimated, coherent, highly monochromatic beams with the possibility of high power densities were considered preferable. However in recent years, non-coherent light sources such as light-emitting diodes (LEDs) and broad-band lamps have become common. Advantages of LEDs include no laser safety considerations, ease of home use, ability to irradiate a large area of tissue at once, possibility of wearable devices, and much lower cost per mW. LED photobiomodulation is here to stay.

Abstract
OBJECTIVE To determine the effects of low-level laser therapy (LLLT) on clinical outcomes in dogs with cranial cruciate ligament disease treated with tibial plateau leveling osteotomy (TPLO). STUDY DESIGN Randomized, placebo-controlled clinical trial. Owners and surgeons (care providers and assessors) were masked. ANIMALS Ninety-five dogs were admitted for TPLO and assigned to 1 of 2 groups, laser group (LG; n = 51) or placebo group (PG; n = 44). METHODS Three treatments (laser or placebo) were administered within a 4-day perioperative period. A fourth treatment was recommended and was accepted in 28.4% of cases (LG, n = 14; PG, n = 13). Dogs in the LG group received laser at wavelengths 660 nm red (100 mW) and at 800, 905 and 970 nm infrared (maximum 15 W continuous wave, 20 W peak pulsed wave), administered simultaneously. Dogs in the PG group received placebo laser (660 nm, 4 mW). Other treatments were identical. Outcomes were measured by difference in clinical metrology instruments (Liverpool Osteoarthritis in Dogs and adjusted Canine Orthopedic Index [COI]), osteotomy healing on a radiographic scale, time to cessation of nonsteroidal anti-inflammatory drug administration, and wound healing by owner questionnaire. RESULTS The only difference detected between groups consisted of a greater improvement in the gait section of the adjusted COI (ACOI) in the LG group (median [interquartile range; IQR] = 6 [4-7.5]) compared with the PG group (median [IQR] = 4 [2-6]; P < .05). CONCLUSION The laser protocol used in this study was associated with a greater improvement in ACOI gait in dogs treated with TPLO but did not improve any other clinical metrology instrument scores or bone healing. CLINICAL SIGNIFICANCE This study provides some evidence that LLLT may improve the gait of dogs recovering from a TPLO, as assessed by owners.

Abstract
The use of opioid analgesics for postoperative pain management has contributed to the global opioid epidemic. It was recently reported that prescription opioid analgesic use often continued after major joint replacement surgery even though patients were no longer experiencing joint pain. The use of epidural local analgesia for perioperative pain management was not found to be protective against persistent opioid use in a large cohort of opioid-naïve patients undergoing abdominal surgery. In a retrospective study involving over 390,000 outpatients more than 66 years of age who underwent minor ambulatory surgery procedures, patients receiving a prescription opioid analgesic within 7 days of discharge were 44% more likely to continue using opioids 1 year after surgery. In a review of 11 million patients undergoing elective surgery from 2002 to 2011, both opioid overdoses and opioid dependence were found to be increasing over time. Opioid-dependent surgical patients were more likely to experience postoperative pulmonary complications, require longer hospital stays, and increase costs to the health-care system. The Centers for Disease Control and Prevention emphasized the importance of finding alternatives to opioid medication for treating pain. In the new clinical practice guidelines for back pain, the authors endorsed the use of non-pharmacologic therapies. However, one of the more widely used non-pharmacologic treatments for chronic pain (namely radiofrequency ablation therapy) was recently reported to have no clinical benefit. Therefore, this clinical commentary will review evidence in the peer-reviewed literature supporting the use of electroanalgesia and laser therapies for treating acute pain, cervical (neck) pain, low back pain, persistent post-surgical pain after spine surgery (“failed back syndrome”), major joint replacements, and abdominal surgery as well as other common chronic pain syndromes (for example, myofascial pain, peripheral neuropathic pain, fibromyalgia, degenerative joint disease/osteoarthritis, and migraine headaches).

Abstract
Background: The aim of this study was to evaluate the efficacy of low-level laser therapy for reducing the acute pain of sternotomy in patients who underwent a coronary artery bypass graft (CABG). Methods: This study was conducted with ninety volunteers who electively submitted to CABG. The volunteers were randomly allocated into three groups of equal size (n = 30): control, placebo, and laser (λ of 660 nm and spatial average energy fluency of 1.06 J/cm2). Pain when coughing was assessed by a visual analog scale (VAS) and McGill Pain Questionnaire, according to sensory, affective, evaluative, and miscellaneous domains. The patients were followed for 1 month after the surgery. Results: The laser group had a greater decrease in pain with analogous results, as indicated by both the VAS and the McGill questionnaire (P ≤ 0.05) on sensory and affective scores, on days 6 and 8 postsurgery compared to the placebo and control groups. Conclusion: Laser seems to be effective promoting pain reduction after coronary-arterial bypass grafting.
