Nine healthy adults (four women; age 24 ± 3 years; body fat 17.9 ± 6.4 %; V̇O2max 48 ± 9 mL·kg·minute-1) completed three visits: a no-immersion control trial and two experimental trials consisting of a four-hour cold-water immersion (20.1±0.3C) either breathing air (FIO2 = 0.21) or O2 (FIO2 = 1.0). During the no-immersion control trial and following immersion in the experimental trials, subjects first completed a 60-minute ruck-march carrying 20% of body mass in a rucksack, immediately followed by an unweighted, self-paced 5-km time trial on a motorized treadmill. Core temperature, heart rate, and rating of perceived exertion were recorded every 1,000 meters during the 5-km time trial. Data are presented mean ± SD. Time trial performance was reduced following immersion in both the 100% O2 trial (32 ± 6 minutes; p=0.01) and air trial (32 ± 5 minutes; p=0.01) compared to the control trial (28 ± 4 minutes). However, there was no difference between the 100% O2 and air trials (p=0.86). Heart rate, core temperature, and rating of perceived exertion increased during the time trial (time effect: p<0.01), but were not different between trials (trial effect: p≥0.33). These findings suggests that prolonged cold-water immersion attenuates self-paced aerobic exercise performance, but does not appear to be further affected by breathing gas type.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77618987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both patients were decannulated within 6 months of presentation and after at least 20 HBO2 therapy sessions. Despite a small sample size, our findings are consistent with data supporting HBO2 therapy’s effects on tissue edema and neovascularization as well as HBO2 potentiation of antibiotic treatment and leukocyte function. We suggest HBO2 therapy may have accelerated airway decannulation by way of infection resolution as well as the revitalization of upper airway tissues, ultimately renewing the structural integrity of the larynx. Physicians should be aware of the potential benefits of HBO2 therapy when presented with this rare but significant clinical challenge.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89274306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: 40 Male Sprague-Dawlay rats were randomly divided into sham, LPS, LPS + HBO, LPS + HRS and LPS + HBO + HRS groups. ALI was induced by an intratracheal injection of LPS, then the rats were respectively given single agent treatment of HBO or HRS or HBO + HRS treatment. The treatments were continued for 3 days in such experimental rat model of ALI. At the end of experiment, the lung pathological , inflammatory factors , and cell apoptosis in the pulmonary tissue were detected by Tunel method and cell apoptosis rate was calculated accordingly. Results: In the groups treated with HBO + HRS, pulmonary pathological data, wet-dry weight ratio and inflammatory factors of pulmonary tissues and aveolar lavage fluid were signficantly superiror to those of the sham group(P<0.05). Cell apoptosis detection revealed that no matter single agent treatment of HRS or HBO, or combination treatment , could all alleviate cell apoptosis, and HRS combined with HBO treatment was obviously superior to single treatment(P<0.05). Conclusions: HRS or HBO single treatment could decrease inflammatory cytokines release in lung tissue, reduce accumulation of oxidative products and alleviate apoptosis of pulmoanry cells, then lead to positive therapeutic effects on ALI induced by LPS. Furthermore, HBO combined with HRS treatment presented a synergy effect on cell apoptosis decrease, and a declined trend in inflammatory cytokines release and related inflammatory products generation, compared with single treatment.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135535034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
