Oxidative stress, inflammatory response and apoptosis are recognized to play important roles in development of this disease. Recently, numerous studies have reported the therapeutic effects of molecular hydrogen (H<sub>2</sub>) on oxidative stress and inflammation-related diseases. Here, the effects of H<sub>2</sub> against glycerol-induced AKI and the underlying mechanisms were explored in rats. Low (4%) and high (67%) concentrations of H<sub>2</sub> were prepared using a self-made device to investigate the dose-response. After 72 hours of glycerol injection (8 mL/kg), we found that glycerol triggered oxidative stress, inflammatory reactions, and apoptotic events. These caused subsequent renal damage, evidenced by a significant reduction of antioxidases and up-regulation of the relevant damaged biomarkers. H<sub>2</sub> inhalation reversed the above alterations and exerted renoprotective effects. Interestingly, for RM/AKI-related factors, no consistent dose-response benefits of H<sub>2</sub> were observed. However, higher concentration of H<sub>2</sub> inhalation improved histological and morphological changes better. This study suggests that H<sub>2</sub> is a potential alternative therapy to prevent or minimize RM induced AKI possibly via its antioxidant, anti-inflammatory, anti-apoptotic and anti-necroptotic properties.</p>","PeriodicalId":18559,"journal":{"name":"Medical Gas Research","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/01/7e/MGR-13-78.PMC9555022.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33493381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The health care systems across the world were suddenly overburdened, due to the rapidly increasing oxygen demand for supporting COVID-19 patients who could not maintain their blood oxygen saturation on their own. Majority of the institutions, states, and countries could not keep up with this sudden surge in oxygen demand and found themselves face to face with an oxygen crisis of epic proportions. Oxygen is critically important for saving lives in emergencies, resuscitation of critical patients, trauma settings, and diseases that primarily affect the respiratory system, like pneumonia. Despite being in the list of essential medicines by World Health Organization,1 the importance of oxygen is usually forgotten due to it being easily available naturally in the environment. Eighty percent of the patients admitted in the United Kingdom due to COVID-19 required supplemental oxygen at higher-than-normal doses.2 The mere thought of oxygen being in short supply, and requiring rationing is alarming, but this is exactly what several health systems had to undergo during this pandemic. The combined efforts of the union government, local administration, and health institutions to maintain adequate supplies of medical grade oxygen during this pandemic proved fruitful, but the demand supply ratio was always under pressure.3 These strenuous circumstances have taught us that even with our best efforts the supply of oxygen would always be precarious, if healthcare providers, individually and collectively, do not find solutions to our increasing demands by implementing protocols for the judicious usage of oxygen. Being a large public sector hospital in the most populous state (Uttar Pradesh) of India, with a bed capacity of more than 3000 beds, and a dedicated COVID-19 facility of more than 900 beds, managing oxygen supplies was not easy during the recently crested second wave of the COVID-19 pandemic. The primary supply of oxygen in our institution is through a vacuum insulated evaporator liquid medical oxygen (LMO) vessel system, with cylinder manifolds as the secondary and backup (reserve) supply. During the second wave of the pandemic, the increasing demands of oxygen at our institution were maintained with the collective efforts of the hospital administration and government agencies.4 Additionally, efforts were done to formulate an “oxygen policy” to check the rising demands, and ensure judicious use of the rapidly diminishing oxygen reserves that we had at our disposal. Here, we try to highlight some of our oxygen conservation strategies that helped us achieve a state of balance in terms of demand and supply of oxygen during the stressful time of the second wave of this pandemic. • Daily oxygen consumption details were traced, and analyzed for the last few months and anticipatory storage of LMO was done ","PeriodicalId":18559,"journal":{"name":"Medical Gas Research","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/85/67/MGR-13-39.PMC9480355.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40682259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both pulsed radiofrequency (PRF) and ozone have good effects on the treatment of the disease. However, whether PRF and ozone have a synergistic effect on PHN remains unclear. Therefore, this study aimed to assess the therapeutic effects of ozone alone and in combination with PRF in the treatment of PHN. Ninety-one patients with PHN were assigned into two groups: PRF combined with ozone (PRF + ozone group, n = 44) and ozone therapy alone (ozone group, n = 47). In PRF + ozone group, the high-voltage, long-duration PRF was applied to the target dorsal root ganglions. Then ozonated water (11.5 µg/mL) was injected through the inner cannula. In the ozone group, all other processes were the same as those in the PRF + ozone group apart from the electrical stimulation. The therapeutic efficacy was evaluated by visual analog scale and tactile sensation at pre-treatment and post-treatment 3, 6, and 12 months. Compared with pre-treatment data, the visual analog scale score was significantly decreased in both groups after treatment. Compared with the ozone group, the visual analog scale score was significantly decreased in the PRF + ozone group at 3, 6, and 12 months. Similarly, the tactile sensation was also significantly decreased at post-treatment when compared to pre-treatment. However, there were no statistical differences between the two groups. Regression analysis results showed that the history of diabetes mellitus and age had significant negative and positive effects, respectively, on the treatment results. To conclude, the administration of PRF + ozone and ozone therapy alone could both improve pain symptoms. Moreover, treatment effects and total efficacy rates tended to be higher for the combination of PRF and ozone than ozone alone.
