New approaches to second-degree burn healing: Polyvinyl alcohol membrane loaded to arnica combined to laser therapy.

Second-degree burns require greater care, as the damage is more extensive and worrisome and the use of a biomaterial can help in the cell repair process, with better planning, low cost, and better accessibility. Arnica has anti-inflammatory and analgesic properties in skin lesions treatments and laser therapy is another therapeutic alternative for burns. Evaluate the effects of arnica incorporated into PVA associated or not with low intensity laser on burns in rats. PVA and PVA with arnica (PVA+A) were obtained and characterized physicochemically. Through in vivo studies, the effects of PVA and PVA+A with or without the application of laser on the lesions allowed histological and immunohistochemical analyzes. PVA+A was biocompatible and with sustained release of the active, being a promising pharmacological tool and confirmed that laser therapy was effective in accelerating the healing process, due to its potential biomodulator, improving inflammatory aspects, promoting rapid healing in skin lesions.

Low-intensity mindfulness and cognitive-behavioral therapy for social anxiety: a pilot randomized controlled trial.

BACKGROUND: Cognitive-behavioral therapy (CBT) effectively improves the clinical symptoms of social anxiety disorder. However, there are non-responders who cannot decrease their cost/probability bias significantly; hence, their social anxiety symptoms remain unaddressed. Mindfulness training and cognitive-behavioral approaches promote a reduction in cost/probability bias and social anxiety symptoms. This study examines the effectiveness of a four-session program of mindfulness and CBT (M-CBT) in a non-clinical sample of individuals with high social anxiety. METHODS: Participants were 50 Japanese undergraduate students (37 women and 13 men) randomly allocated to an intervention group (n = 27) and a control group (n = 23). The intervention group underwent a four-session M-CBT program, while the control group did not receive any treatment. RESULTS: A group × time analysis of covariances showed significant interactions in the negative cognition generated when paying attention to others in probability bias, fear of negative evaluation by others, dispositional mindfulness, depressive symptoms, and subjective happiness. M-CBT also produced significant pre-post improvements in the above outcomes with moderate to high effect sizes (ds = .51-1.55). Conversely, there were no interactions in social anxiety symptoms and self-focused attention. CONCLUSIONS: These results indicate that M-CBT was effective for the negative cognition generated when paying attention to others in probability bias, fear of negative evaluation by others, dispositional mindfulness, depressive symptoms, and subjective happiness. The combination of mindfulness training with cognitive restructuring is proposed as potentially helpful for individuals with probability bias, leading to negative cognition from paying attention to others.

The impact of ischemic vascular stenosis on LIPU hyperthermia efficacy investigated Based on in vivo rabbit limb ischemia model.

Ischemic diseases due to arterial stenosis or occlusion are common and can have serious consequences if untreated. Therapeutic ultrasound like high-intensity focused ultrasound (HIFU) ablates tissues while low-intensity pulsed ultrasound (LIPU) promotes healing at relatively low temperatures. However, blood vessel cooling effect and reduced flow in ischemia impact temperature distribution and ultrasonic treatment efficacy. This work established a rabbit limb ischemia model by ligating the femoral artery, measuring vascular changes and temperature rise during LIPU exposures. Results showed the artery diameter was narrowed by 46.2% and the downstream velocity was reduced by 51.3% after ligation. Finite element simulations verified that the reduced flow velocity impaired heat dissipation, enhancing LIPU-induced heating. Simulation results also suggested the temperature rise was almost related linearly to vessel diameter but decayed exponentially with the increasing flow velocity. Findings indicate that the proposed model could be used as an effectively tool to model the heating effects in ischemic tissues during LIPU treatment. This research on relating varied ischemic flow to LIPU-induced thermal effects is significant for developing safe and efficacious clinical ultrasound hyperthermia treatment protocols for the patients with ischemic diseases.

The effectiveness of low-level laser therapy and low-intensity pulsed ultrasound in reducing pain induced by orthodontic separation: a randomized controlled trial.

BACKGROUND: The low-level laser therapy (LLLT) and low-intensity pulsed ultrasound (LIPUS) have been recently applied to control pain during orthodontic treatment. OBJECTIVE: To evaluate and compare the effectiveness of LLLT and LIPUS in reducing pain induced by orthodontic separation. STUDY DESIGN: A single-blinded randomized controlled trial. METHODS: One hundred and fifty patients were randomly assigned into three groups; LLLT group, LIPUS group, and control group. After 5 min from the separators' placement, the first dose of the laser or the ultrasound was applied, the second dose was applied after 24 h, and the third dose was applied after 48 h on both maxillary and mandibular first molars. The exposure of laser was for 20 s at each point (maxillary and mandibular first molars), with an 810-nm aluminum-gallium-arsenide (AlGaAs) diode laser on continuous mode. The output power set at 150 mW, the energy density of 4 J/cm2, and a laser spot diameter of 7 mm were applied. Whereas the frequency of ultrasonic toothbrush was 1.6 MHz; and average output intensity was 0.2 W/cm2. The application was for 20 min (5 min on each first molar). The control group received the separators without another intervention. A Visual Analog Scale (VAS 100 mm) was used to assess pain intensity at several time intervals during the first four days after the separators' placement. RESULTS: A total of 145 patients were assessed. There was a significant difference in pain perception among the three groups after 5 min (P = .002). The maximum pain level was reached after 24 h. However, the laser group and the ultrasound group showed a statistically significant decrease in pain scores compared to the control group at all the assessment time points (P < .001). Whereas there was no difference between the laser group and the ultrasound group in reducing the pain scores (P > .05). CONCLUSIONS: The LLLT and the LIPUS effectively reduce the separation pain when applied in multiple doses without differences between them. TRIAL REGISTRATION: This trial was registered with the German Clinical Trials Register (DRKS). ( https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID= DRKS00029991).

Attenuation of orthodontically induced inflammatory root resorption by using low-intensity pulsed ultrasound as a therapeutic modality- a systematic review.

Ultrasound is an effective tool for both diagnostic and therapeutic applications. As an imaging tool, ultrasound has mostly been used for real-time noninvasive diagnostic imaging. As ultrasound propagates through a material, a reflected radio-frequency (RF) signal is generated when encountering a mismatch in acoustic impedance. While traditionally recognized for its diagnostic imaging capabilities, the application of ultrasound has broadened to encompass therapeutic interventions, most notably in the form of Low-Intensity Pulsed Ultrasound (LIPUS). Low-Intensity Pulsed Ultrasound (LIPUS) is a form of mechanical energy transmitted transcutaneously by high-frequency acoustic pressure waves. The intensity of LIPUS (30 mW/cm2) is within the range of ultrasound intensities used for diagnostic purposes (1-50 mW/cm2) and is regarded as non-thermal, non-destructive, permeating living tissues and triggering a cascade of biochemical responses at the cellular level. The LIPUS device produces a 200 µs burst of 1.5 MHz acoustic sine waves, that repeats at a modulation frequency of 1 kHz and provides a peak pressure of 30 mW/cm2. Low-intensity pulsed ultrasound (LIPUS) forms one of the currently available non-invasive healing-enhancing devices besides electro-stimulation (pulsed electro-magnetic field, PEMF). This modality has been leveraged to enhance drug delivery, expedite injury recovery, improve muscle mobility, alleviate joint stiffness and muscle pain, and enhance bone fracture healing. Although LIPUS has been embraced within various medical disciplines, its integration into standard dental practices is still in its nascent stages, signifying an unexplored frontier with potentially transformative implications. Low-intensity pulsed ultrasound (LIPUS) has emerged as an attractive adjuvant therapy in various dental procedures, such as orthodontic treatment and maxillary sinus augmentation. Its appeal lies in its simplicity and non-invasive nature, positioning LIPUS as a promising avenue for clinical innovation. One particular area of interest is orthodontically induced inflammatory root resorption (OIIRR), an oftenunavoidable outcome of the orthodontic intervention, resulting in the permanent loss of root structure. Notably, OIIRR is the second most common form of root resorption (RR), surpassed only by root resorption related to pulpal infection. Given the high prevalence and potential long-term consequences of OIIRR, this literature review seeks to evaluate the efficacy of LIPUS as a therapeutic approach, with an emphasis on assessing its capacity to reduce the severity of OIIRR to a level of clinical significance. To conduct this systematic review, a comprehensive automated literature search was executed across multiple databases, including MEDLINE, Embase, PsycINFO, Web of Knowledge, Scopus, CINAHL, LILACS, SciELO, Cochrane, PubMed, trials registries, 3ie, and Google Scholar. Both forward and backward citation tracking was employed, encompassing studies published from database inception through January 2009 to April 2023. The review focused on randomized controlled trials (RCTs) that specifically evaluated the effects of low-intensity pulsed ultrasound therapy on orthodontically induced inflammatory root resorption (OIIRR), without restrictions of publication date. A stringent selection criterion was applied, and only studies demonstrating high levels of statistical significance were included. Ultimately, fourteen studies met the inclusion criteria and were subjected to further analysis. The overall quality of the included randomized controlled trials (RCTs) was rigorously assessed utilizing the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. This analysis revealed certain methodological limitations that posed challenges in drawing definitive conclusions from the available evidence. Despite these constraints, the review offers invaluable insights that can inform and guide future research. Specifically, it delineates recommendations for targeted populations, necessary interventions, appropriate outcome measures, suitable study designs, and essential infrastructure to facilitate further investigations. The synthesis of these insights aims to enhance the development and application of low-intensity pulsed ultrasound therapy within the field of dentistry, thereby contributing to improved patient outcomes.

Application of vascular photobiomodulation therapy in individuals with low back pain and its relationship with global methylation / Aplicação da terapia por fotobiomodulação vascular em indivíduos com lombalgia e sua relação com a metilação global

ABSTRACT BACKGROUND AND OBJECTIVES: Low back pain is among the most disabling conditions worldwide, and among the epigenetic factors, methylation in CpG islands of gene promoter regions can modulate gene expression, potentially correlating with the development of the disease and providing insights into the choice of treatment. The objective of this study was to assess the efficacy of therapy using modified ILIB related to DNA methylation processes in low back pain. Secondary objectives of this study included investigating pain intensity, gender, sociodemographic data, and physical-functional profile. METHODS: This prospective study was conducted in a municipality in the southern region of Brazil. The sample consisted of 30 participants of both genders, with an average age of 41.77 years. The following aspects were analyzed: anthropometric characteristics, global methylation using the ELISA method, pain level, physical activity level, functional disabilities, and hesitancy level related to work and physical activity-related activities. RESULTS: A statistically significant association was observed between methylation levels before and after treatment application for the experimental and placebo groups (p < 0.005), demonstrating a mean responsiveness between methylation and treatment (d = 0.5). However, there were no other statistically significant associations correlated with the other work variables. CONCLUSION: The results obtained in this study suggest the need for further research related to the identification of specific genes in methylation, as well as the standardization of dosimetry used for transcutaneous ILIB laser application in the radial artery.

RESUMO JUSTIFICATIVA E OBJETIVOS: A lombalgia está entre as condições mais incapacitantes no mundo e; dentre os fatores epigenéticos, a metilação em ilhas CpG de regiões promotoras de genes pode modular a expressão gênica permitindo uma possível correlação ao desenvolvimento da doença, como também pode trazer esclarecimentos a respeito do tratamento a ser escolhido. O objetivo deste estudo foi verificar a eficácia da terapia através do uso do ILIB modificado relacionada ao processo de metilação de DNA na lombalgia. Os objetivos secundários deste estudo foram a investigação da intensidade da dor, sexo, dados sociodemográficos e perfil físico-funcional. MÉTODOS: Este estudo, desenvolvido em um município da região sul do Brasil, caracteriza-se como prospectivo. A amostra deste estudo foi composta por 30 participantes, de ambos os sexos, com idade média de 41,77 anos. Foram analisados os seguintes aspectos: características antropométricas, metilação global através do método ELISA, nível de dor, nível de atividade física, incapacidades funcionais e nível de hesitação para realizar atividades relacionada ao trabalho e atividade física. RESULTADOS: Observou-se associação estatisticamente significativa entre os níveis de metilação antes e a após aplicação do tratamento para grupo experimental e placebo (p<0,005) demostrando uma média responsividade entre as variáveis metilação e tratamento (d=0,5). No entanto, não houve nenhuma outra associação estatística correlacionada as demais variáreis do trabalho. CONCLUSÃO: Os resultados obtidos neste estudo sugerem que há necessidade mais estudos relacionados a identificação de genes específicos na metilação, além da necessidade de padronização de dosimetria utilizadas para aplicação do laser ILIB de forma transcutânea, em artéria radial.

Effect of various photobiomodulation regimens on breast cancer-related lymphedema: A systematic review and meta-analysis.

Breast cancer-related lymphedema (BCRL) is common among patients who have completed their cancer treatment. Although low-level laser therapy (LLLT) has been explored as a treatment option for BCRL, we could not find a regimen that is more effective than others. This meta-analysis aimed to organize existing research and determine the optimal combination of LLLT parameters for BCRL treatment. Studies were collected from four online databases: Embase, Ovid Medline, Cochrane, and Cinahl. The collected studies were reviewed by two of the authors. We focused on the aspects of the treatment area, treatment regimen, and total treatment sessions across the included studies. The comparisons between LLLT and non-LLLT were performed through a meta-analysis. Post-treatment QOL was significantly better in the axillary group. The group treated "three times/week with a laser density of 1.5-2 J/cm2" had significantly better outcomes in terms of swelling reduction, both immediately post-treatment and at 1-3 months follow-ups. The group with > 15 treatment sessions had significantly better post-treatment outcomes regarding reduced swelling and improved grip strength. According to these results, LLLT can relieve the symptoms of BCRL by reducing limb swelling and improving QOL. Further exploration found that a treatment approach targeting the axilla, combined with an increased treatment frequency, appropriate laser density, and extended treatment course, yielded better outcomes. However, further rigorous, large-scale studies, including long-term follow-up, are needed to substantiate this regimen.

Use of Phototherapy and Er-YAG Laser in the Management of Mandible Osteoradionecrosis: A Case Report.

Introduction: Osteoradionecrosis (ORN) is a secondary complication from radiotherapy, which is difficult to manage and significantly reduces the life quality of the affected patients. Case Report: A 59-year-old female patient, diagnosed with infiltration by squamous cell carcinoma in the left cervical region, underwent adjuvant cervical-facial radiotherapy with a total dose of 66.6 Gy of radiation. Eight years after the diagnosis, the patient underwent multiple extractions and, subsequently, the installation of osseointegrated implants, evolving to extensive intraoral bone exposure associated with oral cutaneous fistula. The patient was initially exposed to photobiomodulation therapy (PBMT), with a low-power laser at wavelengths of 660 nm and 808 nm, and thereafter to antimicrobial photodynamic therapy (aPDT). After an improvement in the clinical condition and resolution of the oral cutaneous fistula, a surgical procedure with the Er: YAG laser was performed to remove the remaining necrotic bone. Once the ORN condition was completely treated, the patient's oral rehabilitation was implemented by the installation of an upper mucous-supported total prosthesis and a lower implant-supported prosthesis. Conclusion: The patient is in a clinical follow-up and has no signs of bone necrosis recurrence, suggesting that low and high-power laser treatment can be an effective therapeutic alternative to resolve this condition.

Photobiomodulation therapy assisted orthodontic tooth movement: potential implications, challenges, and new perspectives. / ­­æ¿€å ‰å ‰å­ç”Ÿç‰©è°ƒèŠ‚ç–—æ³•è¾ 助正畸牙齿移动：潜在的作用、挑战与新观点.

Over the past decade, dramatic progress has been made in dental research areas involving laser therapy. The photobiomodulatory effect of laser light regulates the behavior of periodontal tissues and promotes damaged tissues to heal faster. Additionally, photobiomodulation therapy (PBMT), a non-invasive treatment, when applied in orthodontics, contributes to alleviating pain and reducing inflammation induced by orthodontic forces, along with improving tissue healing processes. Moreover, PBMT is attracting more attention as a possible approach to prevent the incidence of orthodontically induced inflammatory root resorption (OIIRR) during orthodontic treatment (OT) due to its capacity to modulate inflammatory, apoptotic, and anti-antioxidant responses. However, a systematic review revealed that PBMT has only a moderate grade of evidence-based effectiveness during orthodontic tooth movement (OTM) in relation to OIIRR, casting doubt on its beneficial effects. In PBMT-assisted orthodontics, delivering sufficient energy to the tooth root to achieve optimal stimulation is challenging due to the exponential attenuation of light penetration in periodontal tissues. The penetration of light to the root surface is another crucial unknown factor. Both the penetration depth and distribution of light in periodontal tissues are unknown. Thus, advanced approaches specific to orthodontic application of PBMT need to be established to overcome these limitations. This review explores possibilities for improving the application and effectiveness of PBMT during OTM. The aim was to investigate the current evidence related to the underlying mechanisms of action of PBMT on various periodontal tissues and cells, with a special focus on immunomodulatory effects during OTM.

Effects of photobiomodulation with blue Light Emitting Diode (LED) on the healing of skin burns.

The management of skin burns is still challenging. Among the therapeutic methods used, there are topical treatments with pharmacological and herbal agents, low-intensity therapeutic ultrasound, use of biomaterials, reconstructive techniques and photobiomodulation therapy. The aim of this study was to evaluate the effects of photobiomodulation with blue Light Emitting Diode (LED) on burn healing. Fifty Wistar rats were divided into control (CTRL) (n = 25) and blue LED (LED) (n = 25), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, 28 and 32 days). Treated animals were daily irradiated (470 nm, 1W, 0.44 W/cm2, 50 J/cm2). Clinical evaluations were performed and the Wound Retraction Index (WRI) was determined. Histological sections were submitted to hematoxylin-eosin, toluidine blue and the immunohistochemical technique, with anti-α-SMA and anti-TGF-ß1 antibodies. All data were directly collected by previously calibrated evaluators in a blind manner. The values were included in a statistical program. For all statistical tests used, 5% significance level (p < 0.05) was considered. No statistically significant differences in WRI between groups were observed (p > 0.05). Re-epithelialization was higher using LED at 7 and 14 days (p < 0.05) and greater amount of inflammatory cells was observed at 7 days (p = 0.01). With LED at 21 and 32 days, greater number of mast cells were observed (p < 0.05), as well as smaller number of myofibroblasts at 14, 21, 28 and 32 days (p < 0.05) and lower percentage of TGF-ß1 positive cells in the conjunctiva at 7, 14 and 21 days (p < 0.05). Negative correlations were observed in LED between the percentage of TGF-ß1 in the epithelium and the mean number of inflammatory cells and number of myofibroblasts (p < 0.05). The results suggest that, depending on the period, blue LED can modulate the healing processes of third-degree skin burns, such as re-epithelialization, inflammatory response, mast cell concentration, myofibroblast differentiation and TGF-ß1 immunoexpression. Despite these effects, this therapy does not seem to have significant influence on the retraction of these wounds. Future studies, using different protocols, should be carried out to expand the knowledge about the photobiomodulatory mechanisms of this type of light in the healing process.

LIPUS combined with TFSC alleviates premature ovarian failure by promoting autophagy and inhibiting apoptosis.

OBJECTIVE: Premature ovarian failure (POF), also known as primary ovarian insufficiency, is a major cause of infertility in female worldwide. Excessive apoptosis and impaired autophagy in ovarian granulosa cells are the main pathological mechanisms of POF. The total flavonoids from semen cuscutae (TFSC) are often used in the treatment of gynecological endocrine disorders. In addition, low intensity pulsed ultrasound (LIPUS) is report as an effective method to improve ovarian function. This study aims to investigate the protective effect of POF by the combined use of TFSC and LIPUS. METHODS: POF rats model and granulosa cell model were successfully induced by tripterygium glycosides and cyclophosphamide, respectively. After that, model rats and cells received TFSC plus LIPUS administration. Then ovarian histomorphology, senescence, estrus cycle, and serum sex hormone levels were detected in rats. Ovarian tissue and granulosa cells autophagy and apoptosis levels were also assessed. RESULTS: Disturbed sex hormone levels, atrophied and senescent ovaries, and abnormal estrous cycle were found in POF rats. Meanwhile, cell autophagy was inhibited and cell apoptosis was activated in POF ovarian tissue and granulosa cells. However, TFSC combined with LIPUS improved these changes, and this combination treatment exhibited synergistic effects. The abnormal expression of the cell apoptosis-, autophagy-, and PI3K/AKT/mTOR signaling pathway-related proteins were also improved by combination treatment. CONCLUSION: The study found that the combination of TFSC and LIPUS can alleviate POF by modulating cell autophagy and apoptosis. The findings may provide a viable scientific basis for POF treatment.

Comparing Arsenic-Containing Qinghuang Powder and Low-Intensity Chemotherapy in Elderly Patients with Acute Myeloid Leukemia.

OBJECTIVE: To compare the clinical effect of arsenic-containing Qinghuang Powder (QHP) and low-intensity chemotherapy (LIC) in treatment of elderly acute myeloid leukemia (eAML) patients. METHODS: Clinical data of 80 eAML patients treated at Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2015 to December 2020 were retrospectively analyzed. The treatment scheme was designed by real world study according to patients' preference, and patients were divided into a QHP group (35 cases) and a LIC group (45 cases). The median overall survival (mOS), 1-, 2-, and 3-year OS rates, and incidence of adverse events were compared between the two groups. RESULTS: The mOS of 80 patients was 11 months, and the 1-, 2-, and 3-year OS rates were 45.51%, 17.96%, and 11.05%, respectively. The QHP and LIC groups demonstrated no significant difference in mOS (12 months vs. 10 months), 1- (48.57% vs. 39.65%), 2- (11.43% vs. 20.04%), and 3-year OS rates (5.71% vs. 13.27%, all P>0.05). Moreover, the related factors of mOS demonstrated no significant difference in patients with age>75 years (11 months vs. 8 months), secondary AML (11 months vs. 8 months), poor genetic prognosis (9 months vs. 7 months), Eastern Cooperative Oncology Group performance status score ⩾ 3 (10 months vs. 7 months) and hematopoietic stem cell transplant comorbidity index ⩾ 4 (11 months vs. 7 months) between the QHP and LIC groups (all P>0.05). However, the incidence of myelosuppression was significantly lower in the QHP group than that in the LIC group (28.57% vs. 73.33%, P<0.01). CONCLUSIONS: QHP and LIC had similar survival rates in eAML patients, but QHP had a lower myelosuppression incidence. Hence, QHP can be an alternative for eAML patients who do not tolerate LIC.

Photobiomodulation Reduces Periocular Wrinkle Volume by 30%: A Randomized Controlled Trial.

Objective: This study aimed to evaluate red and amber light-emitting diode protocols for facial rejuvenation at the same light dose. Background: The demand for minimally invasive cosmetic procedures to address skin aging has grown throughout the world. In vitro red and amber photobiomodulation (PBM) has been shown to improve collagen synthesis. Meanwhile, red PBM has already been studied in clinical trials; however, a comparison of the use of different wavelengths at the same light dose to reduce periocular wrinkles has not yet been performed. Methods: This split-face, randomized clinical trial recruited 137 women (40-65 years old) presenting with skin phototypes II-IV and Glogau photoaging scale types II-IV. The individuals received 10 sessions for 4 weeks of red (660 nm) and amber (590 nm) PBM (3.8 J/cm2), one at each side of the face. The outcomes, measured before and after the treatments, were the periocular wrinkle volume measured by VisioFace® RD equipment; hydration measured by the Corneometer CM 825; skin elasticity measured by the Cutometer Dual MPA 580; and quality of life determined by adapted versions of validated questionnaires [Melasma Quality of Life Scale-Brazilian Portuguese (MelasQoL-BP) and Skindex-29]. Results: There was a significant reduction in wrinkle volume after red (31.6%) and amber (29.9%) PBM. None of the treatments improved skin hydration and viscoelasticity. Both questionnaires showed improvements in participants' quality of life. Conclusions: PBM, both at red and amber wavelengths, is an effective tool for rejuvenation, producing a 30% wrinkle volume reduction. The technique has strong potential in patients with diabetes or those presenting with keloids, conditions for which highly inflammatory rejuvenating procedures are not indicated. Clinical trial registration number: REBEC-6YFCBM.

[Treatment of neurological postoperative disorders after surgical intervention for head and neck tumors using low-intensity laser radiation]. / Korrektsiya nevrologicheskikh posleoperatsionnykh narushenii u bol'nykh s opukholyami golovy i shei s ispol'zovaniem nizkointensivnogo lazernogo izlucheniya.

OBJECTIVE: To evaluate the efficacy of low-intensity laser radiation in rehabilitation treatment of patients undergoing radical treatment for head and neck tumors. MATERIAL AND METHODS: The study included 134 patients (39 (29.1%) men, 95 (70, 9%) women), aged from 23 to 78 years old, with an average age of 54.24±12.7 years. Three groups were formed: Group 1 - 45 patients who received the traditional complex of rehabilitation treatment, which includes physical exercise, massage, and drug therapy, without using low-intensity laser radiation; Group 2 - 45 patients who received the traditional complex of rehabilitation treatment in combination with low-intensity laser radiation; Group 3 - 44 patients who underwent only a few low-intensity laser irradiation courses as a rehabilitation treatment. The impact on the tissues of the shoulder joint and cervico-supraclavicular region was carried out by radiation with a wavelength of 660 nm and 970 nm using a matrix radiation source. The course of treatment was 10 treatment sessions lasting 10 minutes. During the first year after radical treatment, the course of laser therapy was repeated every 3 months. In the course of the study, indicators of the patient's subjective assessment of changes occurring with them were studied, depending on the method of rehabilitation used, as well as the restoration of range of motion in the shoulder joint on the side of the operation and the function of soft tissues in the shoulder joint on the radical treatment side. RESULTS: Against the background of the treatment, an improvement in the condition of patients was recorded in the form of a decrease in the severity of motor and sensory disorders. CONCLUSION: Complex rehabilitation treatment with the obligatory use of low-intensity laser radiation provides an improvement in the function of the peripheral nervous system and blood circulation, which, in turn, allows not only to restore the function of these organs, but also to generally improve the quality of life of patients.

Efeitos clínicos da fotobiomodulação como terapia adjuvante não-cirúrgica na periodontite crônica: uma revisão integrativa da literatura / Clinical effects of photobiomodulation as non-surgical adjuvant therapy for chronic periodontitis: an integrative literature review

Objetivos: Analisar os efeitos da fotobiomodulação como terapia adjuvante à raspagem e ao alisamento radicular no tratamento da periodontite crônica publicados nos últimos cinco anos. Métodos: Trata-se de uma revisão integrativa da literatura, realizada no período de setembro a novembro de 2021, mediante a utilização dos seguintes descritores: "Periodontitis", "Photobiomodulation" e "Therapy, selecionando artigos publicados em inglês durante o período entre 2016 a 2021. Resultados: Foram identificados 47 trabalhos. Destes, foram excluídos 39 estudos que se dispersaram do tema e 2 que se encontravam indisponíveis para o acesso, resultando em 6 artigos que foram consultados integralmente. Foi consenso entre os artigos consultados que a prática da fotobiomodulação tornou-se um potencial agente terapêutico no tratamento da periodontite crônica contribuindo para a redução da contagem de periodontopatógenos e que atua de maneira coadjuvante às raspagens radiculares. Conclusão: A fotobiomodulação mostrou-se uma ferramenta promissora na área odontológica. Entretanto, a grande variedade nos parâmetros de tratamentos e protocolos utilizados na fotobiomodulação impossibilita uma comparação e uma análise mais crítica e rigorosa dos resultados obtidos nos trabalhos analisados.

Introduction: Periodontal disease, which has an infectious origin, constitutes a multifactorial and inflammatory different clinical condition of multifactorial, inflammatory, and infectious origin. Photobiomodulation is a non-invasive technique that has been shown to decrease inflammation and provide pain relief. Studies also have shown that the choosing of photobiomodulation as adjuvant therapy to scaling and root planing has been able to reduce the bacterial load from chronic periodontitis. Objectives: To analyze the effects of photobiomodulation as an adjuvant therapy to scaling and root planing in the treatment of chronic periodontitis in the studies published in the last five years. Methods: This is an integrative literature review, carried out from September to November 2021, using the following descriptors: "Periodontitis", "Photobiomodulation" and "Therapy, from selected articles published in English during the period between 2016 to 2021. Results: From the research and selection of studies to compose this integrative literature review, 47 studies were initially identified based on the descriptors. From those, 39 papers that were outside from the topic and 2 papers that were unavailable for access were excluded from the present review. Then remained, 6 articles that were fully consulted. The practice of photobiomodulation has become a potential therapeutic agent in the treatment of chronic periodontitis reducing the count of periodontopathogens and as an adjunct therapy to root scaling. Conclusion: Photobiomodulation therapy has become a promising tool in the dental field, however, the great variety in the treatment parameters and protocols used for photobiomodulation makes impossible to compare and perform a more critical and rigorous analysis of the results collected in the present work.

Low-intensity red-light therapy in slowing myopic progression and the rebound effect after its cessation in Chinese children: a randomized controlled trial.

PURPOSE: To investigate the effect of low-intensity red-light (LRL) therapy on myopic control and the response after its cessation. METHODS: A prospective clinical trial. One hundred two children aged 6 to 13 with myopia were included in the LRL group (n = 51) and the single-focus spectacles (SFS) group (n = 51). In LRL group, subjects wore SFS and received LRL therapy provided by a laser device that emitted red-light of 635 nm and power of 0.35 ± 0.02 mW. One year after the control trial, LRL therapy was stopped for 3 months. The outcomes mainly included axial length (AL), spherical equivalent refraction (SER), subfoveal choroidal thickness (SFCT), and accommodative function. RESULTS: After 12 months of therapy, 46 children in the LRL group and 40 children in the SFS group completed the trial. AL elongation and myopic progression were 0.01 mm (95%CI: - 0.05 to 0.07 mm) and 0.05 D (95%CI: - 0 .08 to 0.19 D) in the LRL group, which were less than 0.39 mm (95%CI: 0.33 to 0.45 mm) and - 0.64 D (95%CI: - 0.78 to - 0.51 D) in the SFS group (p < 0.05). The change of SFCT in the LRL group was greater than that in the SFS group (p < 0.05). Accommodative response and positive relative accommodation in the LRL group were more negative than those in the SFS group (p < 0.05). Forty-two subjects completed the observation of LRL cessation, AL and SER increased by 0.16 mm (95%CI: 0.11 to 0.22 mm) and - 0.20 D (95%CI: - 0.26 to - 0.14 D) during the cessation (p < 0.05), and SFCT returned to baseline (p > 0.05). CONCLUSIONS: LRL is an effective measure for preventing and controlling myopia, and it may also have the ability to improve the accommodative function. There may be a slight myopic rebound after its cessation. The effect of long-term LRL therapy needs to be further explored.

Eficácia de um protocolo de laseracupuntura sobre a fadiga e alterações respiratórias pós- covid-19: estudo quase experimental / Effectiveness of a laseracupuncture protocol on post- covid-19 fatigue and lung capacity: a quasi-experimental study / Eficacia de un protocolo de laseracupuntura sobre cambios respiratorios de la fatiga y poscovida-19: estudio casi experimental

Objetivo: Estudo quase experimental aprovado pelo Comitê de Ética em Pesquisas com Seres Humanos ­ COPEP da Universidade Estadual de Maringá, sob Parecer nº. 5.262.784, cujo objetivo foi avaliar a segurança e eficácia da laseracupuntura como uma abordagem terapêutica complementar no tratamento da fadiga e capacidade pulmonar em pacientes pós-COVID. Materiais e método: Nos meses de fevereiro e maço de 2023, no ambulatório de enfermagem da Universidade Estadual do Paraná, Campus de Paranavaí, foram recrutados 23 pacientes da comunidade acadêmica (discentes, docentes e agentes universitários) da própria universidade, com idade mediana de 24 anos (IQR = 22,0, 32,0), com diagnóstico prévio de COVID-19 e que apresentavam sintomas de fadiga e queixa de desconforto respiratório por pelo menos quatro semanas após a recuperação da fase aguda da doença. Dados demográficos, socioeconômicos e de estado de saúde geral e relacionados à COVID-19 foram coletados. Os pacientes foram tratados com duas sessões semanais de laseracupuntura por um período de cinco semanas. Para identificação da presença e intensidade da fadiga, foi aplicada a Escala de Fadiga de Piper Revisada com 23 itens e dividida em três dimensões, no início e final do tratamento e realizados testes de função pulmonar por espirometria para descrição do padrão ventilatório dos voluntários, em todas as sessões. Resultados: Participaram 23 voluntários com idade mediana de 24 anos (IQR, 22-32) e predominantemente do sexo feminino (N= 15 [65%]) e da cor branca (N = 13 [56,4%]). A maioria dos voluntários tinha sobrepeso ou obesidade (N = 16 [79,6%]). Após a fase aguda da COVID-19, os sintomas mais relatados foram ansiedade (65%), queda de cabelo (35%) e dor de cabeça (30%). Todos os participantes apresentaram fadiga intensa pós-COVID (6,36 [IQR = 6,00 ­ 7,73]). Os resultados do estudo mostraram que o tratamento com a laseracupuntura resultou em redução significativa nas pontuações da escala de fadiga quanto à Dimensão comportamental (Diferença média [DM] = -1,65; IC 95%; 0,56-2,75; p < 0,001) Dimensão afetiva (DM = -2,43; IC 95%; 1,33-3,52; p < 0,001) e Dimensão sensorial (DM= -2,85; IC 95%; 2,08-3,63; p < 0,001), além do total geral de fadiga (-2,44; IC 95%; 1,63-3,24; p < 0,001), mas não apresentou qualquer efeito nas medidas de função pulmonar como Capacidade Vital Forçada (DM = -0,87; IC 95%; -4,24, 5,98); p = 0,727), manobra básica avaliada em espirometria e relação entre Volume expiratório forçado em 1 segundo (VEF1) e Capacidade vital forçada (CVF), o VEF1/CVF (DM = -1,00; IC 95%; -10,38-8,39; p = 0,828). Nenhum efeito colateral foi relatado durante o tratamento. Conclusão: O protocolo de laseracupuntura foi seguro e bem tolerado pelos pacientes, sem efeitos colaterais relatados durante o tratamento, sugerindo que a laseracupuntura pode ser uma opção segura para o tratamento da fadiga pós-COVID-19. Apesar da intervenção não ter provocado efeito nos padrões respiratórios dos voluntários, estes verbalizaram melhora da expansibilidade e dor torácica, aumento do fôlego e disposição. Sugere-se novos estudos controlados para melhor compreensão do manejo dos sintomas pós-agudos da COVID-19.

Objective: Quasi-experimental study approved by the Ethics Committee for Research with Human Beings ­ COPEP of the State University of Maringá, Opinion nº. 5,262,784, whose objective was to evaluate the safety and efficacy of laser acupuncture as a complementary therapeutic approach in the treatment of fatigue and lung capacity in post-COVID patients. Materials and method: In February and March 2023, at the nursing clinic of the State University of Paraná, Campus Paranavaí, 23 patients were recruited from the academic community (students, professors and university agents) of the university itself, with a median age of 24 years old (IQR = 22.0, 32.0), with a previous diagnosis of COVID-19 and who had symptoms of fatigue and a complaint of respiratory distress for at least four weeks after recovery from the acute phase of the disease. Demographic, socioeconomic, and general health and COVID-19 related data were collected. The patients were treated with two laseracupuncture sessions per week for a period of five weeks. To identify the presence and intensity of fatigue, the Revised Piper Fatigue Scale was applied, with 23 items and divided into three dimensions, at the beginning and end of treatment, and pulmonary function tests were performed by spirometry to describe the ventilatory pattern of the volunteers, in all sessions. Results: Participants were 23 volunteers with a median age of 24 years (IQR, 22-32) and predominantly female (N = 15 [65%]) and Caucasian (N = 13 [56.4%]). Most volunteers were overweight or obese (N = 16 [79.6%]). After the acute phase of COVID-19, the most reported symptoms were anxiety (65%), hair loss (35%) and headache (30%). All participants experienced severe post-COVID fatigue (6.36 [IQR = 6.00 ­ 7.73]). The results of the study showed that treatment with laser acupuncture resulted in a significant reduction in scores on the fatigue scale for the Behavioral Dimension (Mean difference [MD] = -1.65; CI 95%; 0.56-2.75; p < 0.001) Affective dimension (DM = -2.43; CI 95%; 1.33-3.52; p < 0.001) and Sensory dimension (DM = -2.85; CI 95%; 2.08-3, 63; p <0.001), in addition to the fatigue grand total (-2.44; 95% CI; 1.63-3.24; p < 0.001), but had no effect on measures of lung function such as Forced Vital Capacity (MD = -0.87; 95% CI; -4.24, 5.98); p = 0.727), basic maneuver evaluated in spirometry and ratio between Forced Expiratory Volume in 1 Second (FEV1) and Forced Vital Capacity (FVC), FEV1/FVC (DM = -1.00; CI 95%; -10.38 -8.39; p = 0.828). No side effects were reported during treatment. Conclusion: The laseracupuncture protocol was safe and well tolerated by patients, with no reported side effects during treatment, suggesting that laseracupuncture may be a safe option for treating post-COVID-19 fatigue. Although the intervention had no effect on the breathing patterns of the volunteers, they reported improvement in chest expansion and pain, increased breath and disposition. New controlled studies are suggested to better understand the management of post-acute symptoms of COVID-19.

Se han recopilado datos demográficos, socioeconómicos y de salud general relacionados con el programa COVID-19. Los pacientes fueron tratados con dos sesiones de laseracupuntura por semana durante cinco semanas. Para la identificación de la presencia y la intensidad de la fatiga, se revisó la escala de fatiga de los piper con 23 elementos y se dividió en tres dimensiones, al inicio y al final del tratamiento, y se realizaron pruebas de función pulmonar mediante espirometría para describir el patrón de ventilación de los voluntarios, en todas las sesiones. Resultados: participaron 23 voluntarios con una edad media de 24 años (RCI, 22-32) y predominantemente mujeres (N = 15 [65%]) y blancas (N = 13 [56,4%]). La mayoría de los voluntarios presentaron sobrepeso u obesidad (N = 16 [79,6%]). Después de la fase aguda de COVID-19, los síntomas notificados más frecuentemente fueron ansiedad (65%), pérdida de pelo (35%) y dolor de cabeza (30%). Todos los participantes presentaron fatiga grave post-COVID (6,36 [IQR = 6,00 - 7,73]). Los resultados del estudio mostraron que el tratamiento con laseracupuntura dio lugar a una reducción significativa de las puntuaciones de la escala de fatiga para la dimensión conductual (Diferencia media [DM] = -1,65; IC del 95%; IC del 0,56-2,75; p < 0,001) La dimensión afectiva (DM = -2,43; IC del 95%: 1; 33-3,52; p < 0,001) y dimensión sensorial (DM = -2,85; IC del 95% 2,08-3,63; p < 0,001), además de la fatiga general (-2,44; IC del 95%: 1,63-3,24; p < 0,0 01), pero no tuvo efecto sobre las medidas de función pulmonar como capacidad vital forzada (DM = -0,87; IC del 95%; -4,24,5,98); p = 0,727), maniobra basal evaluada en espirometría y relación entre el volumen respiratorio forzado 1 segundo (VEF1) y la capacidad viciosa forzada (CVF), EF1/CVF (DM = -1,00; IC del 95%; -10,38-8,39; p = 0,828). No se notificaron efectos adversos durante el tratamiento. Conclusión: El protocolo de laseracupuntura fue seguro y bien tolerado por los pacientes, sin efectos secundarios notificados durante el tratamiento, lo que sugiere que la laseracupuntura puede ser una opción segura para el tratamiento de la fatiga post-COVID-19. Aunque la intervención no tuvo efecto sobre los patrones respiratorios de los voluntarios, verbalizaron mejoría en la capacidad de expansión y dolor torácico, dificultad respiratoria y disposición. Se sugieren nuevos estudios controlados para entender mejor el manejo de los síntomas post-agudos de COVID-19.

A pandemia da COVID-19, provocou um grande impacto na saúde mental das pessoas, mesmo após a fase aguda da doença, resultando em altas taxas de ansiedade e depressão, tornando necessário o desenvolvimento e a avaliação de tratamentos, não farmacológicos, eficazes para aliviar esses sintomas. Este estudo quase-experimental, aberto, unicêntrico, realizado nos meses de fevereiro e março de 2023, no ambulatório de enfermagem da Universidade Estadual do Paraná, campus de Paranavaí, teve como objetivo avaliar a eficácia da Laseracupuntura, para o tratamento de ansiedade e depressão, na Síndrome Pós-COVID-19. O estudo foi aprovado pelo Comitê de Ética (Parecer nº. 5.262.784). Foram coletados dados demográficos, socioeconômicos e de estado de saúde. A presença e a intensidade de ansiedade e depressão foram verificadas no início e, ao final, do tratamento, por meio do Inventário de Ansiedade de Beck (21 itens) e Inventário de Depressão de Beck (21 itens). Ao todo, 23 voluntários receberam até 10 sessões, de um protocolo de Laseracupuntura, para tratar ansiedade e depressão pós-COVID-19. Os pontos P1, PC6, E36, E25, VC6, VC12, VC17 e Yintang, foram estimulados por luz de laser infravermelho sobre a pele. Os participantes eram predominantemente, mulheres, de raça/cor branca e tinham sobrepeso ou obesidade. Os sintomas pós-agudos da COVID-19, mais relatados, foram: ansiedade, queda de cabelo e dor de cabeça. A mediana inicial de pontuação das escalas de ansiedade e depressão foram de 23,00 (IQR, 13,50 ­ 27,50) e 22,00 (IQR, 11,50 ­ 26,50), respectivamente. A intervenção resultou em reduções significativas, nas pontuações de duas escalas: de ansiedade (DM = -9,74; IC 95%, 4,88 ­ 14,60; p < 0,001) e depressão (DM = -9,87; IC 95%; 5,53 ­ 14,21; p < 0,001). Nenhum efeito colateral foi relatado durante o tratamento. Os resultados obtidos neste estudo, sugerem que, a Laseracupuntura pode ser uma terapia eficaz e segura para tratar sintomas de ansiedade e depressão em pacientes pós-COVID-19. Além disso, o uso da laseracupuntura, tem a vantagem adicional de ser menos invasiva que a Acupuntura tradicional, tornando-a uma opção atraente para pessoas que buscam tratamentos integrativos para saúde mental, sem os riscos presentes em terapias medicamentosas tradicionais. Recomenda-se a realização de mais estudos ­ principalmente ensaios clínicos randomizados ­, para confirmar a eficácia da Laseracupuntura.

The COVID-19 pandemic has had a major impact on people's mental health even after the acute phase of the disease, resulting in high rates of anxiety and depression, making it necessary to develop and evaluate treatments, non- pharmacological, effective to alleviate these symptoms. This quasi-experimental, open- label, unicentric study, conducted in February and March 2023, at the nursing outpatient clinic at Paraná State University, Paranavaí campus, aimed to evaluate the effectiveness of Laseracupuncture, for the treatment of anxiety and depression, in Post-COVID-19 Syndrome. The study was approved by the Ethics Committee (Opinion No. 5 262 784). Demographic, socioeconomic and health status data were collected. The presence and intensity of anxiety and depression were verified at the beginning and at the end of the treatment, through the Beck Anxiety Inventory (21 items) and Beck Depression Inventory (21 items). In all, 23 volunteers received up to 10 sessions of a Laseracupuncture protocol to treat post-COVID-19 anxiety and depression. The points P1, PC6, E36, E25, VC6, VC12, VC17 and Yintang, were stimulated by infrared laser light on the skin. Participants were predominantly women of white race/color and were overweight or obese. The most reported post-acute symptoms of COVID-19 were: anxiety, hair loss, and headache. The median baseline scores for the anxiety and depression scales were 23.00 (IQR, 13.50 - 27.50) and 22.00 (IQR, 11.50 - 26.50), respectively. The intervention resulted in significant reductions in the scores of two scales: anxiety (DM = -9.74; 95% CI, 4.88 - 14.60; p < 0.001) and depression (DM = -9.87; 95% CI; 5.53 - 14.21; p < 0.001). No side effects were reported during treatment. Results obtained in this study suggest that Laseracupuncture may be an effective and safe therapy for treating symptoms of anxiety and depression in post-COVID-19 patients. In addition, the use of laseracupuncture has the additional advantage of being less invasive than traditional Acupuncture, making it an attractive option for people seeking integrative treatments for mental health, without the risks present in traditional drug therapies. Further studies - mainly randomized clinical trials - are recommended to confirm the efficacy of Laseracupuncture.
