ABSTRACT

Hyperbaric Oxygen Therapy (HBOT) assumes that high pressure hyperoxygenation causes faster tissue recovery and wound healing. Lower extremity flow rates are affected by leg ulcers that change vasodilation, microcirculation resistance, and local tissue demands; how blood hyper oxygenation influences these factors is still unclear. Peripheral arterial occlusive disease (PAOD) has been mostly associated with HBOT results in the femoral artery than in other arteries. Common femoral artery (CFA) peak systolic velocities (PSV), measured pre and post HBOT, were analyzed to research HBOT hemodynamics. Sixteen patients with leg ulcers who were 65 ± 11 (SD) (38-87) years-old, had HBOT of 90 minutes at 2.6 ATA. Bilateral CFA Doppler velocity waveforms were recorded immediately pre and post HBOT. Ulcerated vs non-ulcerated peak systolic velocity (PSV) data were compared using paired t-test. CFA PSV were significantly equal in the ulcerated and non-ulcerated extremities before HBOT: 114 ± 35 (SD) cm/s vs 116 ± 41 cm/s (p = 0.87 by paired t-test). CFA PSV in the ulcerated extremity increased to 122 ± 35 cm/s after HBOT but were statistically insignificant (p =.19 by one-tailed paired t-test). On the other hand, CFA PSV decreased to 103 ± 28 cm/s (p =.049 by one-tailed paired t-test) in the non-ulcerated extremity and were significantly lower after HBOT, with 103 ± 28 cm/s vs 122 ± 35 cm/s for the ulcerated limb (p =.02 by paired t-test). Blood velocity responses post HBOT showed differences between ulcerated vs non-ulcerated extremities. The non-ulcerated extremity apparently responded to oxygenation more than the ulcerated extremity. Such observation suggests further research on hemodynamic reactions caused by HBOT.


A oxigenoterapia hiperbárica (HbOT) assume que a oxigenação de alta pressão resulta em mais celeridade na recuperação do tecido e na cicatrização de feridas. As taxas de fluxo nas extremidades inferiores são afetadas por úlceras nas pernas que alteram a vasodilatação, a resistência da microcirculação e as demandas locais de tecido; esses fatores podem ser influenciados pela hiperoxigenação sanguínea de maneiras ainda não claramente compreendidas. A doença arterial oclusiva periférica femoral (DAOP) tem sido associada a melhores resultados de HBOT quando comparada a outras artérias. As velocidades sistólicas de pico (PSV) da artéria femoral comum (CFA) medidas antes e depois da HBOT foram analisadas como parte de um projeto de pesquisa da hemodinâmica da HBOT. Dezesseis pacientes com úlceras de perna, com idade 65 ± 11 (DP), 38-87 anos, realizaram HBOT com duração de 90 minutos a 2,6 ATA. As formas de onda de velocidade do Doppler CFA bilateral foram registradas imediatamente antes e depois da HBOT. Os dados de PSV ulcerado vs. não ulcerado foram comparados usando o teste t pareado. Pre HBOT CFA PSV não foi significativamente diferente nas extremidades ulceradas e não ulceradas: 114 ± 35 (DP) cm/s vs 116 ± 41 cm/s (p = 0,87 pelo teste t pareado). O PSV pós HbOT CFA na extremidade ulcerada aumentou para 122 ± 35 cm/s, mas não atingiu significância estatística (p = 0,19 pelo teste t pareado unicaudal). Em contraste, CFA PSV na extremidade não ulcerada diminuiu para 103 ± 28 cm/s (p = 0,049 pelo teste t pareado unicaudal). O pós-HbOT CFA PSV foi significativamente menor no membro não ulcerado, 103 ± 28 cm/s vs 122 ± 35 cm/s para o membro ulcerado (p = 0,02 pelo teste t pareado). As respostas da velocidade do sangue após HbOT mostraram diferenças entre as extremidades ulceradas e não ulceradas. Aparentemente, a extremidade não ulcerada respondeu mais significativamente à oxigenação do que a extremidade ulcerada. Tal observação sugere pesquisas adicionais sobre as reações hemodinâmicas decorrentes da HbOT.


La terapia de oxígeno hiperbárico (HbOT) asume que la hiperoxigenación a alta presión da como resultado una recuperación más rápida de los tejidos y una cicatrización de heridas. Las tasas de flujo de las extremidades inferiores se ven afectadas por úlceras en las piernas que alteran la vasodilatación, la resistencia de la microcirculación y las demandas de los tejidos locales; estos factores pueden verse influenciados por la hiperoxigenación de la sangre, de formas que aún no se han entendido con claridad. La enfermedad oclusiva arterial periférica femoral (PAOD) se ha relacionado con los mejores resultados de HbOT que otras arterias. Las velocidades sistólicas máximas (PSV) de la arteria femoral común (CFA) medidas antes y después de la HbOT se analizaron como parte de un proyecto para investigar la hemodinámica de la HbOT. Dieciséis pacientes con úlceras en pierna, 65 ± 11 (DE) (38-87) años, 12 hombres, 11 diabéticos, tenían HbOT de 90 minutos a 2,6 ATA. Se registraron formas de onda de velocidad de CFA Doppler bilaterales inmediatamente antes y después de la HbOT. Se compararon los datos de la velocidad sistólica máxima (PSV) ulcerada frente a la no ulcerada mediante la prueba t pareada. Pre HbOT CFA PSV no fue significativamente diferente en las extremidades ulceradas y no ulceradas: 114 ± 35 (DE) cm/s vs 116 ± 41 cm/s (p = 0,87 por prueba t pareada). Post HbOT CFA PSV en la extremidad ulcerada aumentó a 122 ± 35 cm/s pero no alcanzó significación estadística (p =.19 por prueba t unilateral pareada). En contraste, CFA PSV en la extremidad no ulcerada disminuyó a 103 ± 28 cm/s (p =.049 por prueba t unilateral pareada). El PSV después de la HbOT CFA fue significativamente menor en la extremidad no ulcerada, 103 ± 28 cm/s frente a 122 ± 35 cm/s para la extremidad ulcerada (p = 0,02 según la prueba t pareada). Las respuestas de velocidad sanguínea post HbOT mostraron diferencias entre las extremidades ulceradas y no ulceradas. Aparentemente, la extremidad no ulcerada respondió más significativamente a la oxigenación que la extremidad ulcerada. Tal observación sugiere una mayor investigación sobre las reacciones hemodinámicas debidas a la HbOT.

ABSTRACT

Cutaneous manifestations of dermatomyositis are unusual and difficult to treat. This study aimed to report a case of cutaneous manifestations of dermatomyositis treated with hyperbaric oxygen. We present a case of dermatomyositis in a 44-year-old female with pain ulcers in her left leg for 17 months, refractory to an exclusive clinical treatment, who underwent a hyperbaric oxygen therapy (HBOT) breathing O2 100%, 90 minute sessions, six days a week, at 2.4 ATA. HBOT therapy proved to be highly efficacious in wound healing in this case and HBOT should be considered as a treatment in the assistance given to such patients.

ABSTRACT

Hyperbaric oxygenation (HBO2) is a successful treatment of diabetic foot ulcerations. Research on the characterization of tissue by ultrasonography (CATUS) or by imaging (CATIM) has grown. We investigated the photographic pCATIM feasibility to quantitate HBO2 effects. Besides, we analyzed pre and post HBO2 treatment photographs quantitatively based on pixel brightnesses of gray-scale imaging versions. Grayscale Medians (GSM) for (1) entire ulceration, (2) inner core, (3) ulceration border, and (4) adjacent skin decreased from 92 to 77, 60 to 56, 105 to 101, and 105 to 90. Entire ulceration post-HBO2 pixel percentages were lower in the 112-153 intervals, 11% vs 29% (p = .0013 by Chi-square), and higher in the 41-111 brightness range, 87% vs 68% (p = .0008). A case report showed quantifiable relative changes detected by pCATIM post HBO2 treatment of diabetic foot ulceration. Further investigation may quantify brightness variabilities and/or specific GSM for ulceration and skin regions.


A oxigenioterapia hiperbárica (HBO2) tem sido um tratamento de sucesso para úlceras do pé diabético, enquanto cresce o número de pesquisas caracterizando o tecido por meio de ultrassonografia (Catus) ou imagem (Catim) ­ sendo que a pCatim torna viável quantificar os efeitos da oxigenioterapia hiperbárica. Fotografias do pré e pós tratamento foram analisadas quantitativamente com base em brilhos de pixel de versões de imagens em escala de cinza. Houve redução das medianas da escala de cinza (gray scale medians ­ GSM) para (1) ulceração inteira, de 92 para 77; (2) núcleo interno, de 60 para 56; (3) borda da ulceração, de 105 para 101; e (4) pele adjacente, de 105 para 90. Na úlcera completa, após a HBO2, as porcentagens de pixels foram menores nos intervalos 112-153 (11% contra 29%, p = 0,0013 por qui-quadrado) e maiores na faixa de brilho 41-111 (87% contra 68%, p = 0,0008). Um relato de caso demonstrou mudanças relativas quantificáveis detectadas por pCatim após o tratamento com HBO2 de uma úlcera do pé diabético, e investigações mais aprofundadas podem quantificar as variabilidades de brilho e/ou GSM específicas para cada ulceração e regiões da pele.


La oxigenación hiperbárica (HBO2) ha sido un tratamiento exitoso de las ulceraciones del pie diabético. Ha crecido la investigación sobre la caracterización de tejidos por ecografía (CATUS) o por imágenes (CATIM). Se investigó la viabilidad fotográfica de pCATIM para cuantificar los efectos de HBO2. Las fotografías anteriores y posteriores al tratamiento con HBO2 se analizaron cuantitativamente en función del brillo de los píxeles de las versiones de imágenes en escala de grises. Medianas de escala de grises (GSM) para (1) ulceración completa, (2) núcleo interno, (3) borde de ulceración y (4) piel adyacente disminuyeron de 92 a 77, 60 a 56, 105 a 101 y 105 a 90, respectivamente. En la ulceración completa, después de HBO2, los porcentajes de píxeles fueron más bajos en los intervalos 112-153, 11% vs 29% (p = .0013 por Chi-cuadrado) y más altos en el rango de brillo 41-111, 87% vs 68% (p = .0008). Un informe de caso demostró cambios relativos cuantificables detectados por pCATIM después del tratamiento con HBO2 de una ulceración del pie diabético. Una investigación adicional puede cuantificar las variaciones de brillo y o GSM específico para ulceraciones y regiones de la piel.

ABSTRACT

Abstract Contact electrical burns are more severe than other forms of contact burn injury. Moreover, treatment of hand burns is an important therapeutic challenge. We present a 17 year-old female of low voltage electric hand injury, admitted 5 days after injury. The patient was treated with autologous platelet rich plasma, porcine dermis heterograft and partial autologous skin graft, all of them with hyperbaric oxygen therapy (HBOT) at 1.45 ATA ≈100% O2 like adjuvant therapy. Good evolution and acceptable aesthetic results were reported. Although more studies are required, we suggest that multi-therapeutic approach could be effective in treatment for electric burns in hands.


Resumen Las quemaduras eléctricas por contacto son más graves que otras formas de quemaduras. Además, el tratamiento de las mismas en las manos es un importante desafío terapéutico. Presentamos el caso de una mujer de 17 años de edad con lesión en la mano por quemadura por electricidad de baja tensión. Fue ingresada 5 días después de la lesión y tratada con plasma rico en plaquetas autólogo, heteroinjerto de dermis porcina e injerto de piel autólogo parcial, todo con oxigenoterapia hiperbárica (TOHB) a 1.45 ATA ≈100% O2 como terapia adyuvante. Tuvo buena evolución y resultados estéticos aceptables. Aunque se requieren más estudios, sugerimos que el enfoque multi-terapéutico podría ser eficaz en el tratamiento de las quemaduras eléctricas en las manos.

ABSTRACT

We investigated the local and systemic effects of hyperbaric oxygen therapy in BALB/C mice, exposed to two different exposure times, under 2.4 atmosphere (ATM). Fifteen animals were divided into three groups (GI, GII and Control) and underwent a surgical excision of a skin fragment of approximately one square centimeter of the dorsal region. The wounds were treated and monitored for 21 days. In the control group, the wound was cleaned once a day with sterile 0.9% NaCl solution. GI and GII mice were submitted to daily hyperbaric oxygen therapy of 30 or 60minutes sessions, respectively. The wounds were photographed every three days and their surfaces were analyzed by an image analyzer. At 21 days, all animals were euthanatized for histopathological analysis of the skin, lungs and liver in order to identify eventual alterations in wound healing or in the analyzed organs. Animals belonging to GI showed a faster skin wound healing in comparison to the other groups. Animals from GII, however, showed a delayed wound healing process and exhibited lung and microcirculatory alterations. These findings allow us to conclude that the exposure time to the oxygen in hyperbaric environment is crucial and can help or disturb skin wound healing or even be deleterious to other organs.(AU)


Investigaram-se os efeitos locais e sistêmicos da oxigenoterapia hiperbárica em camundongos BALB / C, submetidos a dois tempos de exposição diferentes, sob atmosfera 2,4 (ATM). Quinze animais foram divididos em três grupos (GI, GII e controle) e submetidos à excisão cirúrgica de fragmento de pele de aproximadamente um centímetro quadrado da região dorsal. As feridas foram tratadas e acompanhadas por 21 dias. No grupo controle, a ferida foi limpa uma vez ao dia, com solução estéril de NaCl 0,9%. Camundongos GI e GII foram submetidos à oxigenoterapia hiperbárica diária de 30 ou 60 minutos de sessões, respectivamente. As feridas foram fotografadas a cada três dias, e suas superfícies analisadas por um analisador de imagens. Aos 21 dias, todos os animais foram submetidos à eutanásia para análise histopatológica da pele, do pulmão e do fígado, em busca de eventuais alterações na cicatrização da ferida ou nos órgãos analisados. Animais pertencentes ao GI apresentaram cicatrização mais rápida de feridas cutâneas em comparação aos outros grupos. Já os animais do GII apresentaram retardo na cicatrização da ferida e alterações pulmonares e microcirculatórias. Esses achados permitem concluir que o tempo de exposição ao oxigênio em ambiente hiperbárico é fundamental e pode auxiliar ou atrapalhar a cicatrização de feridas cutâneas ou mesmo ser deletério para outros órgãos.(AU)

ABSTRACT

OBJECTIVES@#This study was performed to investigate the effects of hyperbaric oxygen and other approaches for treating the osteoradionecrosis of the jaws (ORNJ) systematically.@*METHODS@#According to the preset inclusion and exclusion criteria, randomized controlled trials and cohort studies on hyperbaric oxygen in the treatment of ORNJ were screened, and foreign language databases such as PubMed, EMBASE, and Cochrane library were searched via a computer; Chinese databases such as CNKI, VIP, Wanfang data, and CBM were searched from the established database to September 2020. Relevant books were searched manually to collect all literatures on the efficacy of hyperbaric oxygen and its related therapies in ORNJ treatment. Two researchers were independent and mutually blind, the papers were selected, data were collected, and the bias risk was evaluated. If any difference was detected, it would be decided by discussion or arbitrated by a third party. The data related to the efficacy of hyperbaric oxygen and its related therapy in the treatment of the ORNJ were extracted, and the Revman5.4 software was used for Meta-analysis. In case of large heterogeneity, sensitivity analysis was performed. A funnel chart was used to evaluate possible publication bias qualitatively.@*RESULTS@#Four randomized controlled trials and seven cohort studies were included in Meta-analyses. In ORNJ treatment, no significant differences between the group subjected to hyperbaric oxygen and both surgery and antibiotics and the group that underwent both surgery and antibiotics (RR=1.16, 95%CI: 0.86~1.58, @*CONCLUSIONS@#Hyperbaric oxygen therapy cannot replace surgery and antibiotic therapy. Hyperbaric oxygen therapy is not superior to antibiotics and antifibrotic drugs, but the benefits of antifibrotic drugs should be further explored.

ABSTRACT

BACKGROUND@#Hyperbaric oxygen treatment (HBOT) has been demonstrated to influence the keloid recurrence rate after surgery and to relieve keloid symptoms and other pathological processes in keloids. To explore the mechanism of the effect of HBOT on keloids, tumor immune gene expression and immune cell infiltration were studied in this work.@*METHODS@#From February 2021 to April 2021, HBOT was carried out on keloid patients four times before surgery. Keloid tissue samples were collected and divided into an HBOT group (keloid with HBOT before surgery [HK] group, n = 6) and a non-HBOT group (K group, n = 6). Tumor gene expression was analyzed with an Oncomine Immune Response Research Assay kit. Data were mined with R package. The differentially expressed genes between the groups were compared. Hub genes between the groups were determined and verified with Quantitative Real-time PCR. Immune cell infiltration was analyzed based on CIBERSORT deconvolution algorithm analysis of gene expression and verified with immunohistochemistry (IHC).@*RESULTS@#Inflammatory cell infiltration was reduced in the HK group. There were 178 upregulated genes and 217 downregulated genes. Ten hub genes were identified, including Integrin Subunit Alpha M (ITGAM), interleukin (IL)-4, IL-6, IL-2, Protein Tyrosine Phosphatase Receptor Type C (PTPRC), CD86, transforming growth factor (TGF), CD80, CTLA4, and IL-10. CD80, ITGAM, IL-4, and PTPRC with significantly downregulated expression were identified. IL-10 and IL-2 were upregulated in the HK group but without a significant difference. Infiltration differences of CD8 lymphocyte T cells, CD4 lymphocyte T-activated memory cells, and dendritic resting cells were identified with gene CIBERSORT deconvolution algorithm analysis. Infiltration levels of CD4 lymphocyte T cell in the HK group were significantly higher than those of the K group in IHC verification.@*CONCLUSION@#HBOT affected tumor gene expression and immune cell infiltration in keloids. CD4 lymphocyte T cell, especially activated memory CD4+T, might be the key regulatory immune cell, and its related gene expression needs further study.

ABSTRACT

Many studies have shown that high-altitude exposure could significantly influence human cognition, and the approaches which could enhance the human cognition in high-altitude hypoxia environment attract great attention. In the present study, we recruited a total of 60 subjects who had been migrated to Tibet University as adults for more than one year. These participants were randomly divided into the experimental group and the control group. The participants in the experimental group were instructed to complete a hyperbaric oxygen treatment, and those in the control group just completed a wait condition. By using the attention network test (ANT), the changes of the attention function before and after a single session of hyperbaric oxygen treatment were explored. The results showed that single hyperbaric oxygen treatment significantly improved the orienting function of attention, with an obvious post-intervention effect, but not the alerting and conflict function of attention. We also found a strong association between alerting function and conflict function after the end of intervention, suggesting the change of the overall performance of attention function. The present findings might suggest that the improvement of attention function by a single session of hyperbaric oxygen intervention is derived from the increase of general cognitive resources, rather than the transfer of cognitive resources within the attention system.

ABSTRACT

Resumen Se realiza una revisión narrativa que plantea una reflexión acerca del rol de la oxigenación hiperbárica en la recuperación de los intoxicados con monóxido de carbono (ICO). La relación presión de tratamiento de oxigenación hiperbárica (TOHB), o sea dosis de oxígeno, y demora en su implementación son descriptas en esta revisión. Se presentan 9 casos de pacientes con ICO tratados con TOHB a 1,45 ATA (Atmósferas absolutas) por falta de acceso a TOHB de alta presión. Si bien es necesario investigación adicional, sugerimos que esta modalidad terapéutica a 1,45 ATA para ICO debe ser elegida frente al oxígeno normobárico, y considerada cuando las instalaciones de alta presión no están disponibles a distancias razonables.


Abstract A narrative review that raises a reflection about the role of hyperbaric oxygenation in the recovery of monoxide carbon (CO) poisoning is carried out. A description of the relationship of the pressure of hyperbaric oxygen therapy (HBOT), oxygen dosage, and the delay in its implementation was done. Nine cases of intoxications treated with HBOT at 1.45 ATA due to lack of access to high-pressure HBOT were presented. While additional research is necessary, we suggest that this therapeutic modality at 1.45 ATA (Absolute Atmospheres) should be chosen instead of normobaric oxygen therapy for CO poisoning, and considered when high pressure facilities are not available at reasonable distances.

Pessoas com idade de 61-72 anos tiveram maior tempo de sessões (mediana = 40 sessões). A regressão por modelagem linear utilizando como preditor a variável tempo de tratamento pela doença, demonstrou significância estatística do tabagismo e doença hematológica. Discussão: Os achados corroboram com estudos sobre a ocorrência de feridas. Conclusão: O estudo de prevalência poderá contribuir para a elaboração de um plano de cuidados de enfermagem individualizado ao portador de feridas que realizam tratamento no setor de oxigenoterapia hiperbárica. (AU)


Objective: Describe the prevalence of types of wounds indicated for hyperbaric oxygen therapy. Method: cross-sectional, quantitative and retrospective study. Were analyzed medical records of patients seen in the hyperbaric medicine sector for the period from January to December 2015. Descriptive and analytical statistics were used. Results: In the 60 medical records analyzed, the following were prevalent: age between 19-49 years and 61-72 years (both with 27,1%), male (68,3%), Diabetes Mellitus (44,1%) and surgical dehiscence (20,3%). People aged 61-72 years had longer sessions (median = 40 sessions). Regression by linear modeling using the variable duration of treatment for the disease as a predictor, demonstrated statistical significance of smoking and hematological disease. The findings corroborate with studies on the occurrence of wounds. Conclusion: The prevalence study may contribute to the development of an individualized nursing care plan for patients with wounds undergoing treatment in the hyperbaric oxygen therapy sector. (AU)

Casuistic and Method: Cross-sectional, retrospective, and descriptive study based on the analysis of physical records of patients with GF submitted to hyperbaric oxygen therapy through the hyperbaric chamber from February 2008 to May 2018, assisted at the hyperbaric oxygen therapy clinic, in Bauru, SP. The data collected were age, gender, etiology, comorbidities, lesion location and extension, total session number, and mortality. Result: It totaled 38 patients, 76% male, with a mean age of 55.6 years. Among the patients, 17 (44.7%) were discharged, 18 (47.4%) discontinued treatment before termination, and three (8.21%) deaths occurred. The main etiology was an abscess and the main predisposing comorbidities were diabetes mellitus and hypertension. The location and extension lesion with the most affected areas were in the scrotal region, followed by the perineal region. Conclusion: The results of this study demonstrated that the effect of HBOT as an adjuvant treatment has an advantage in the treatment of GF resulting in considerable patient medical discharge and low mortality.

ABSTRACT

OBJECTIVE@#To compare the therapeutic effect of electro-nape-acupuncture (ENA) combined with hyperbaric oxygen therapy (HBOT) and single HBOT on refractory flat descending idiopathic sudden sensorineural hearing loss (ISSNHL).@*METHODS@#A total of 78 patients were randomized into an ENA combined with HBOT (ENA+HBOT) group and a HBOT group, 39 cases in each one. Patients in both groups were treated with oral extract of ginkgo biloba leaves and mecobalamin tablets. On the basis of the conventional medication treatment, HBOT was adopt in the HBOT group. On the basis of the treatment in the HBOT group, electro-nape-acupuncture was applied at Fengchi (GB 20), Gongxue (Extra), Zhongzhu (TE 3), Waiguan (TE 5) and Yifeng (TE 17), Tinggong (SI 19), Tinghui (GB 2) and the vertigo-auditory area of affected side in the ENA+HBOT group. Pulse acupuncture instrument was connected at Fengchi (GB 20) and Gongxue (Extra) for 30 min (with continuous wave, 2 Hz in frequency), the needles were retained for another 30 min after electroaupuncture. The treatment was given once a day, 6 times a week for 4 weeks in both groups. Before the treatment and 2,4 weeks into the treatment, the average auditory threshold, the scores of tinnitus handicap inventory (THI) and dizziness handicap inventory (DHI) were observed, and the therapeutic effect was evaluated in both groups.@*RESULTS@#Compared before treatment, the average auditory threshold, the scores of THI and DHI of 2,4 weeks into the treatment were decreased in both groups (0.05).@*CONCLUSION@#Electro-nape- acupuncture can improve the mean auditory threshold and the symptoms of tinnitus and dizziness in patients with refractory flat descending idiopathic sudden sensorineural hearing loss.

ABSTRACT

Objective@#Hyperbaric oxygen treatment (HBOT) has demonstrated efficacy in improving hearing levels of patients with idiopathic sudden sensorineural hearing loss (ISSHL); however, the underlying mechanisms are not well understood. HBOT alleviates the inflammatory response, which is mediated by Toll-like receptor (TLR) 4 and nuclear factor (NF)-κB. In this study we investigated whether HBOT attenuates inflammation in ISHHL patients alteration of TLR4 and NF-κB expression.@*Methods@#ISHHL patients ( = 120) and healthy control subjects ( = 20) were enrolled in this study. Patients were randomly divided into medicine group treated with medicine only ( = 60) and HBO group receiving both HBOT and medicine ( = 60). Audiometric testing was performed pre- and post-treatment. TLR4, NF-кB, and TNF-α expression in peripheral blood of ISSHL patients and healthy control subjects was assessed by ELISA before and after treatment.@*Results@#TLR4, NF-κB, and TNF-α levels were upregulated in ISSHL patients relative to healthy control subjects; the levels were decreased following treatment and were lower in the HBO group than that in the medicine group post-treatment ( < 0.05 and < 0.01).@*Conclusion@#HBOT alleviates hearing loss in ISSHL patients by suppressing the inflammatory response induced by TLR4 and NF-κB signaling.

ABSTRACT

RESUMO Objetivo Avaliar a relação entre a adesão à oxigenoterapia domiciliar prolongada (ODP) e a mortalidade em pacientes com doença pulmonar obstrutiva crônica (DPOC) e insuficiência respiratória crônica e suas características clínicas. Métodos Análise retrospectiva longitudinal de 254 pacientes com DPOC e insuficiência respiratória crônica no período de 2008 a 2016. No início do estudo, avaliamos o diagnóstico, valores espirométricos, gasometria arterial, hemograma, oximetria de pulso, composição corporal e questionários de saúde (dispnéia, qualidade). vida, ansiedade e depressão). Para a análise de adesão referida ao ODP, foram incluídos 199 pacientes, divididos de acordo com a prescrição de oxigênio: 12h/dia (G1), 15h/dia (G2) e 24h/dia (G3). As causas e datas da morte foram estudadas durante o período de cinco anos. Resultados Em cinco anos, identificamos 124 óbitos (62,3%). Não houve diferença significativa na mortalidade entre os grupos de adesão (p = 0,75) e não encontramos diferenças nos parâmetros clínicos avaliados. A prescrição de ODP não foi associada à mortalidade (p = 0,07). Na análise de regressão de Cox, não houve associação entre mortalidade e não adesão ao ODP (HR: 0,75; IC95%: 0,21-2,70). O risco de mortalidade aumentou no G3 em comparação ao G1 (HR: 7,16; IC 95%: 1,44-35,38) e naqueles com maior escore de depressão (HR: 1,35; IC: 1,14-1,59). Conclusão Não foi encontrada associação entre adesão à ODP e mortalidade em pacientes com DPOC e insuficiência respiratória. Não houve diferenças clínicas entre os grupos de adesão.


ABSTRACT Objective Assess the relationship between adherence to long-term oxygen therapy (LTOT) with mortality in patients with chronic obstructive pulmonary disease (COPD) and chronic respiratory failure and their clinical features. Methods Longitudinal retrospective analysis of 254 patients with COPD and chronic respiratory failure from 2008 to 2016. At baseline, we evaluated the diagnosis, spirometry values, arterial blood gas analysis, blood count, pulse oximetry, body composition and health questionnaires (dyspnea, quality of life, anxiety and depression). For referred adherence analysis to LTOT we included 199 patients, divided according to prescription of oxygen: 12h/day (G1), 15h/day (G2) and 24h/day (G3). The cause of death and dates were studied over the five-year period. Results In five years we identified 124 deaths (62.3%). No significant difference was found in mortality between the adherence groups (p=0.75) nor did we find differences in the clinical parameters evaluated. LTOT prescription was not associated with mortality (p=0.07). In Cox regression analysis, there was no association between mortality and non-adherence to LTOT (HR: 0.75; IC95%: 0.21-2.70). The risk of mortality was increased in G3 compared with G1 (HR: 7.16; IC 95%: 1.44-35.38) and in those with a higher depression score (HR: 1.35; IC: 1.14-1.59). Conclusion No association was found between LTOT adherence and mortality in patients with COPD and respiratory failure. There were no clinical differences between the adherence groups.

ABSTRACT

OBJECTIVES: Mesenchymal stem cells (MSCs) are potentially ideal for type 2 diabetes treatment, owing to their multidirectional differentiation ability and immunomodulatory properties. Here we investigated whether the stem cells from human exfoliated deciduous teeth (SHED) in combination with hyperbaric oxygen (HBO) could treat type 2 diabetic rats, and explored the underlying mechanism. METHODS: SD rats were used to generate a type 2 diabetes model, which received stem cell therapy, HBO therapy, or both together. Before and after treatment, body weight, blood glucose, and serum insulin, blood lipid, pro-inflammatory cytokines (tumor necrosis factor-alpha and interleukin-6), and urinary proteins were measured and compared. After 6 weeks, rats were sacrificed and their organs were subjected to hematoxylin and eosin staining and immunofluorescence staining for insulin and glucagon; apoptosis and proliferation were analyzed in islet cells. Structural changes in islets were observed under an electron microscope. Expression levels of Pdx1, Ngn3, and Pax4 mRNAs in the pancreas were assessed by real-time quantitative polymerase chain reaction (RT-qPCR). RESULTS: In comparison with diabetic mice, those treated with the combination or SHE therapy showed decreased blood glucose, insulin resistance, serum lipids, and pro-inflammatory cytokines and increased body weight and serum insulin. The morphology and structure of pancreatic islets improved, as evident from an increase in insulin-positive cells and a decrease in glucagon-positive cells. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining of islet cells revealed the decreased apoptosis index, while Ki67 and proliferating cell nuclear antigen staining showed increased proliferation index. Pancreatic expression of Pdx1, Ngn3, and Pax4 was upregulated. CONCLUSION: SHED combined with HBO therapy was effective for treating type 2 diabetic rats. The underlying mechanism may involve SHED-mediated increase in the proliferation and trans-differentiation of islet β-cells and decrease in pro-inflammatory cytokines and apoptosis of islets.

ABSTRACT Objective To evaluate cardiorespiratory alterations due to a single session of hyperbaric oxygen therapy. Method Randomized study with patients: a control group and hyperbaric oxygen therapy. Evaluations occurred in the beginning, during, and after exposure to pure oxygen above atmosphere for 2 hours. Systemic blood pressure, peripheral oxygen saturation, pulse rate, lung volume and lung capacity, and maximal inspiratory and expiratory pressures were evaluated. Peripheral oxygen saturation, pulse rate, and systemic blood pressure were evaluated during the pressurizing in the first hour. Data were evaluated by means of ANOVA, Mann-Whitney, and independent t-test (p<0.05). Results A total of 14 adult patients were evaluated. In the group under therapy (seven subjects), aged: 49.57±14.59 years, there was a decrease in the pulse rate of 16 beats per minute after 35 minutes of therapy (intragroup analysis), and the peripheral oxygen saturation was higher within the same period compared to the control group. Conclusion The hyperbaric oxygen therapy promotes cardiorespiratory alterations with the increase of the peripheral oxygen saturation and decrease of the pulse rate, without altering blood pressure levels and the strength, volumes, and respiratory capacities.

ABSTRACT

Introduction: Acute acoustic trauma, which is a kind of sensorineural hearing loss, is caused by acoustic overstimulation. Hyperbaric oxygen therapy (HBOT) is reported to be effective against acute acoustic trauma. Objective: We aimed to evaluate the efficacy of HBOT against acoustic hearing loss based on our 20 years of experience with such cases. Methods: Patients who were treated with HBOT for acute acoustic trauma between April 1997 and August 2017 were evaluated in this study. Thirty-five patients with a mean age of 25.7 ± 9.2 (range: 16­48) years were included. Thirty-nine out of 70 ears (35 patients) were damaged. We investigated the initial level of hearing loss; the extent to which hearing recovered; subjective symptoms, such as tinnitus and aural fullness; and the treatment administered. Results: The planned HBOT was completed in 37 of 39 ears. Twenty-six of the 37 ears (70.2%) displayed improved hearing, and 31 of the 37 ears (83.9%) exhibited symptom improvement. Twenty-three (76.7%) and 26 (86.7%) of the 30 ears treated with steroids demonstrated improvements in hearing and subjective symptoms, respectively. Conclusion: A combination of HBOT and steroids should be considered as a treatment for acute acoustic trauma in cases involving symptoms such as tinnitus and aural fullness (AU)
