Effect of superficial adipose tissue mitochondrial and cellular functionality induced by extracorporeal shock wave therapy (ESWT).

Due to its regenerative action, extracorporeal shock wave therapy (ESWT) is applied in treating integumentary and musculoskeletal diseases. However, other potential therapeutic interventions are being investigated. It is essential to fully understand its mitochondrial signaling pathway to achieve this, which plays a fundamental role in elucidating the mechanism of action and possible therapeutic interventions. Thus, this study aimed to analyze the effect of ESWT on mitochondrial pathways through the relationship between lipolysis and adipocyte apoptosis, as well as cellular functionality. This is a non-randomized case-control clinical trial where obese women received ESWT sessions in the abdominal region, after which tissue samples were collected for histological and immunohistochemical analyses of adipose tissue. The data demonstrated positivity in the expression of mitochondrial markers related to cell apoptosis, such as FIS1 (p < 0.0203) and OPA1 (p < 0.0283), in addition to the positivity of anti-MFN1, responsible for regulating mitochondrial cell proliferation (p < 0.0003). In summary, this study demonstrates that ESWT was able to activate specific mitochondrial signaling pathways, which may be associated with its ability to stimulate lipolysis and apoptosis in superficial adipose tissue. However, no significant improvements in cellular functionality were observed.

Photobiomodulation therapy with light-emitting diode in stimulating adipose tissue mitochondria.

Low-level laser therapy (LLLT) is known for its ability to induce a photochemical process, primarily targeting mitochondria, a process referred to as photobiomodulation (PBM). Recently, its use has been attributed as an adjunct in obesity treatment, to stimulate lipolysis and apoptosis. However, the pathway of stimulation remains uncertain. Thus, the objective of this study was to understand whether mitochondrial stimulation occurs in adipose tissue cells after PBM therapy, which could lead to the processes of lipolysis and apoptosis. A non-randomized clinical trial was conducted using a split abdomen design in obese women who received red and infrared LED photobiomodulation therapy (PBMT). The patients underwent bariatric surgery, and adipose tissue samples were collected for immunohistochemical analysis with primary mitochondrial antibodies. Adipose tissue samples subjected to LED intervention exhibited positivity in mitochondrial antibodies for cAMP, DRP1, FAS, FIS1, MFN2, and OPA1 (p<0.001) compared to the control group. In conclusion, we observed that PBMT was capable of generating mitochondrial stimulation in adipose tissue cells, as evidenced by the positive antibody signals. This finding suggests that mitochondrial stimulation could be the mechanism and action underlying adipose tissue lipolysis and apoptosis.

Effects of LED photobiomodulation therapy on the subcutaneous fatty tissue of obese individuals - histological and immunohistochemical analysis.

Photobiomodulation therapy (PBMT) has become an adjuvant therapeutic possibility in body remodeling procedures. Given this scenario, this study was proposed with the aim of evaluating the effects of PBMT to Light Emitting Diode (LED) associating the red (630 nm) and infrared (850 nm) wavelengths in the subcutaneous fatty tissue. This controlled study of comparative intervention that evaluated a sample of subcutaneous fatty tissue from women with grade II obesity. The participants received the LED PBMT treatment with associated red and infrared wavelengths sequentially on the left side of the abdomen and the right side was considered as control, with the collection of biological material performed at the time of bariatric surgery. For histological and immunohistochemical evaluation, Caspase 3, Cleaved Caspase 3, CD68+, HSL and adipophilin markers were used. The participants showed positivity in the expression of Caspase 3 and Cleaved Caspase (p < .0001), CD68+ macrophages (p < .0001), HSL (p < .0001) and adipophilin (p < .0013) in the intervention sample when compared to the control. PBMT and LED associating red and infrared wavelengths were able to promote autophagic lipolysis induced by adipocyte cell apoptosis in the subcutaneous tissue of obese individuals.

Effect of extracorporeal shock waves on inflammation and angiogenesis of integumentary tissue in obese individuals: stimulating repair and regeneration.

The technology of extracorporeal shock wave therapy (ESWT) has been studied around the world for its possible benefits in the treatment and rehabilitation of aesthetic disorders. To better elucidate its real physiological effect on the integumentary tissue, this study was proposed aimed at evaluating whether ESWT can act to stimulate the inflammatory process and angiogenesis in the dermis and epidermis of obese individuals. This is an immunohistological study that evaluated a set of samples of the integumentary tissue of women with grade II obesity with weight loss of 10% of the initial weight undergoing ESWT treatment; the collection of biological material was performed at the time of surgery of bariatric surgery. For immunohistochemical evaluation, the markers to assess the presence and distribution of inflammatory cells, anti-COX-2, CD3, CD20, CD163, and NK were used. For physiological stimulus pathways for blood vessel angiogenesis, markers CD 34, CD 105 and VEGF were used. Fourteen obese women were included in the study. Positivity was evidenced in the epidermal expression of markers of the inflammatory process COX-2, CD3, CD20, NK cells, CD68, and CD163 (p < 0.0001) in the intervention sample when compared to controls. There was a positive expression for the angiogenesis markers CD105 and VEGF (p < 0.0001) when comparing the intervention group with the control group. It was concluded that ESWT can stimulate a local inflammatory process, mediating and modulating important growth factors to act in the repair process and skin tissue regeneration, being considered a promising treatment for skin diseases related to weight gain or loss.

High power Q-switched 1064 nm / 532 nm Nd:YAG Laser in tattoo removal: A systematic review.

Q-switched 1064 nm/532 nm Nd: YAG Lasers present important characteristics which can contribute toward the removal of tattoos, for having the ability to reach only specific targets with minimal damage to the tissue. Despite reports of their clinical benefits, only a few scientific studies demonstrate the efficacy and safety of these types of lasers in the short and long term. To substantiate the effects, benefits, and safety of the application of Q-switched 1064 nm/532 nm Nd: YAG lasers, a systematic review was carried out from September to December of 2019, about the studies which report their use in the removal of tattoos, published in the last 20 years. Randomized clinical trials in humans were considered, as long as they evaluated the efficacy, safety, and benefits of the application of Q-switched 1064 nm/532 nm Nd: YAG lasers in the removal of black and color tattoos in different skin phototypes. One hundred and twenty-two articles were identified after the titles, abstracts were read, and duplicates were removed; six articles were left, which were included in the research (188 individuals). The Q-switched 1064 nm/532 nm Nd: YAG lasers seem promising in the short term, with minimal adverse effects; however, the efficacy and safety in the long term still present limitations. Consequently, future research is necessary, with better methodological standardization applied and with a follow-up for a longer period of evaluation of possible permanent adverse effects, to determine the standardization and safety of the therapy with the lasers Nd: YAG de 1064 nm/532 nm Q-switched.

Efficacy, safety, and guidelines of application of the fractional ablative laser erbium YAG 2940 nm and non-ablative laser erbium glass in rejuvenation, skin spots, and acne in different skin phototypes: a systematic review.

Non-ablative and ablative fractional erbium lasers are among the most frequently used resources in dermatology for facial rejuvenation and for treating dermatological disorders. This type of erbium laser can be found at wavelengths of 1540 or 1550 nm, which are classified as non-ablative erbium glass, and at 2940 nm, classified as ablative erbium YAG. Despite the reports of their clinical benefits, few scientific studies have demonstrated the efficacy and safety of these lasers in the short or long term. In order to substantiate the effects, benefits, and safety of applying the erbium glass and erbium YAG lasers, a systematic review was carried out from August to December 2019 about studies published in the last 20 years. Randomized clinical trials in humans were considered that evaluated the efficacy, safety, and benefits of applying the fractional lasers erbium glass and erbium YAG to facial rejuvenation, skin spots, and atrophic acne scars. A total of 338 articles were identified; 76 articles remained after their titles and abstracts were read, and 42 articles were selected after removing the duplicates. After the articles were read in full, 17 of these articles were included in the systematic review (453 patients). The erbium glass and erbium YAG lasers seem promising in the short term, with minimal adverse effects; however, the long-term efficacy and safety still present limitations. Consequently, future research is needed, with better methodological standardization and a follow-up with a longer evaluation period for possible permanent adverse effects to determine the standardization and safety of therapy with erbium glass and erbium YAG lasers.

Efficacy and safety of ND:YAG 1064 nm lasers for photoepilation: a systematic review.

Using light sources in phototherapy has presented promising results regarding several types of facial and body skin affections for centuries. The neodymium-doped yttrium aluminum garnet (ND:YAG) 1064 nm laser has become a standard treatment in dermatology for dermatological disturbances related to the pilous follicle and the structures surrounding it. Despite the reports of its clinical benefits, few scientific studies show its actual safety and efficacy. To substantiate the effects, benefits, and safety of applying an ND:YAG 1064 laser in the epilation process during esthetic treatment, a systematic review was carried out between October 2018 and January 2019, on studies published in the last 20 years. Randomized clinical trials in humans were considered that evaluated the efficacy, safety, and benefits of ND:YAG laser application at 1064 nm wavelengths for hair removal. A total of 198 articles were identified; 58 articles remained after their titles and abstracts were read; and 21 articles were selected after the removal of duplicates. After the integral reading, 13 of these articles were included in the systematic review (734 patients). The ND:YAG 1064 nm laser presents safety and promising, beneficial effects in epilation. However, further scientific studies with better methodologic quality are necessary to better standardize ND:YAG laser therapy and clarify its parameters for photoepilation.

Respiratory evaluation through volumetric capnography among grade III obese and eutrophic individuals: a comparative study

ABSTRACT BACKGROUND: Excess trunk body fat in obese individuals influences respiratory physiological function. The aims of this study were to compare volumetric capnography findings (VCap) between severely obese patients and normal-weight subjects and to assess whether there is any association between neck circumference (NC), waist-hip ratio (WHR) and VCap among grade III obese individuals. DESIGN AND SETTING: Analytical observational case-matched cross-sectional study, University of Campinas. METHODS: This cross-sectional study compared VCap variables between 60 stage III obese patients and 60 normal-weight individuals. RESULTS: In comparison with the normal-weight group, obese patients presented higher alveolar minute volume (8.92 ± 4.94 versus 6.09 ± 2.2; P = < 0.0001), CO2 production (278 ± 91.0 versus 209 ± 60.23; P < 0.0001), expiratory tidal volume (807 ± 365 versus 624 ± 202; P = 0.005), CO2 production per breath (21.1 ± 9.7 versus 16.7 ± 6.16; P = 0.010) and peak expiratory flow (30.9 ± 11.9 versus 25.5 ± 9.13; P = 0.004). The end-expiratory CO2 (PetCO2) concentration (33.5 ± 4.88 versus 35.9 ± 3.79; P = 0.013) and the phase 3 slope were normalized according to expired tidal volume (0.02 ± 0.05 versus 0.03 ± 0.01; P = 0.049) were lower in the obese group. CONCLUSIONS: The greater the NC was, the larger were the alveolar minute volume, anatomical dead space, CO2 production per minute and per breath and expiratory volume; whereas the smaller were the phase 2 slope (P2Slp), phase 3 slope (P3Slp) and pressure drop in the mouth during inspiration.

Food Intolerance 1 Year After Banded Roux-En-Y Gastric Bypass.

The purpose of this study is to evaluate the food intolerance after banded Roux-en-Y gastric bypass (RYGB), correlating the data of food ingestion. METHODS: This is an observational prospective study, which evaluated the individuals before and 3, 6, and 12 months after banded RYGB. We performed an anthropometric evaluation and an assessment of the habitual food ingestion and applied a food tolerance questionnaire. RESULTS: The study group was comprised of 75 individuals, 89% of them female, with a percentual weight loss of 29.73 ± 6.79%. The observed results were that food intolerance increased over time and 1 year after surgery, only 2.7% reported to ingest any type of food, while the greatest difficulty was related to red meat (80%). Regarding vomits, after surgery, this proportion significantly increased after 3, 6, and 12 months. Preoperatively, the mean protein ingestion was 98 g, which decreased to 50 g after 3 and 6 months and to 51 g after 12 months. As a conclusion, food intolerance significantly increased following banded RYGB, leading to a crescent dissatisfaction regarding food and an increase in the vomits frequency.

Obstructive sleep apnea syndrome among obese individuals: A cross-sectional study.

INTRODUCTION: The obstructive sleep apnea syndrome (OSAS) is a respiratory illness, characterized by recurrent episodes of apnea and hypopnea, leading to reduction or cessation of the airflow. Obesity is one of the major risk factors for the development of OSAS. To help in the diagnosis of this disease, easily applicable and low-cost questionnaries were developed, such as the Berlin Questionnaire (BQ). OBJECTIVE: To evaluate the efficacy of the BQ for the screening of OSAS among candidates to bariatric surgery in a multidisciplinary preoperative program. METHOD: This is an observational, descriptive and cross-sectional study which evaluated obese individuals that were being prepared for bariatric surgery by means of the BQ. RESULTS: BQ was able to detect that minimal variations in the body mass index, neck circumference and hip-to-waist ratio lead to changes in the risk to develop OSAS; the higher the values of these variables, the higher the risk for OSAS development. CONCLUSION: BQ was an efficient and reliable tool to demonstrate the high risk for OSAS development in individual with obesity.

Resumo Introdução: A síndrome da apneia obstrutiva do sono (SAOS) é uma patologia respiratória, caracterizada por episódios recorrentes de apneia e hipopneia, resultando na cessação ou redução do fluxo aéreo. A obesidade é um dos principais fatores de risco para o desenvolvimento da SAOS. Foram criadas formas de auxiliar o diagnóstico da doença por meio de questionários de fácil aplicação e baixo custo, como o questionário de Berlim (QB). Objetivo: Avaliar a eficácia do QB para rastreamento do risco de desenvolvimento da SAOS em indivíduos portadores de obesidade que participaram do grupo multidisciplinar de preparo pré-operatório para cirurgia bariátrica do Hospital de Clínicas da Universidade Estadual de Campinas (HC-Unicamp). Método: O estudo foi observacional, descritivo e transversal, e avaliou portadores de obesidade que participavam do Programa multidisciplinar de preparo pré-operatório para cirurgia bariátrica do HC-Unicamp foram avaliados por meio do QB. Resultados: O QB foi capaz de detectar que mínimas oscilações no índice de massa corpórea (IMC), na circunferência cervical (Ccv), na circunferência da cintura e na relação cintura/quadril (RCQ) podem alterar o risco de desenvolvimento de SAOS, sendo que quanto maior esses valores, maior o risco de desenvolvimento de SAOS. Conclusão: O QB é uma ferramenta eficaz e fidedigna em demonstrar a prevalência do risco alto para o desenvolvimento da SAOS em indivíduos portadores de obesidade, dado esse que, quando correlacionado com IMC, aumento de idade, medida de cintura, Ccv e RCQ, faz o risco tender a aumentar de forma exponencial.
