Background/Aim. Opto-magnetic imaging spectroscopy (OMIS) was used as a novel method to determine tissue molecular conformation changes during hyperbaric oxygen (HBO) therapy. The aim of this study was to examine the usefulness of OMIS for the assessment of HBO therapy effectiveness on the diseased tissue. Method. OMIS is concerned with obtaining paramagnetic/diamagnetic properties of materials, related to the presence of unpaired/paired electrons based on their interaction with visible light. The basic tool is light of wavelength in the range between 400 nm and 700 nm and its interaction with tissue. The study included 22 subjects: 16 angiopathy patients and 6 healthy subjects as the control group. OMIS was used with patients on the 1st, 10th and 20th session and with the control group on the 1st, 10th and 20th day without HBO therapy in between. Results. The obtained results showed that healthy skin of all the control group subjects had the same shape curve. In the angiopathy patient group, before the first session OMIS showed tissue disorder and after the last session results resembled more closely the results in healthy tissue. The differences in the tissue state in the angiopathy group before each session were noticeable, showing normalized tissue under the influence of HBO. Conclusion. The results showed that OMIS could be used as a diagnostic tool for detection of the tissue state before and after the HBO therapy.

Recent studies have shown that hyperbaric oxygen (HBO) has a therapeutic effect on vascular dementia (VD); however, the exact mechanism remains unclear. This article aims to reveal the protective effects and underlying mechanisms of HBO on VD. A total of 158 patients with VD were prospectively included in the study and were randomly divided into control group and HBO group. The control group was given conventional treatment and the HBO group was treated with HBO in addition to conventional treatment. The following HBO protocol was practiced: 5 days per week, 60 min each, 100% oxygen at 2 standard atmospheric pressures for 12 weeks. The Mini-Mental State Examination (MMSE) scores and serum Humanin levels were detected before and after treatments in both groups. The baseline characteristics were not different dramatically between groups ( p > 0.05). There was no significant difference in MMSE scores and serum Humanin levels between the two groups before treatment ( p > 0.05). After treatment, compared with the control group, the MMSE scores and serum Humanin levels in the HBO group were significantly increased ( p < 0.05). Spearman correlation analysis showed that the serum Humanin levels were positively correlated with MMSE scores ( r = 0.409, p < 0.05) and this correlation was independent of baseline characteristics (β = 0.312, p < 0.05). HBO therapy can improve cognitive function in patients with VD, and its mechanism may be related to elevated serum Humanin levels.

AbstractIntroduction:Although major sequelae of carbon-monoxide (CO) poisoning and its treatment with hyperbaric oxygen (HBO) are well-documented, a syndrome of low-level CO poisoning has received relatively little attention. Subtle symptoms of poor concentration, language difficulty, problems with calculations, and memory loss were noted after an acute exposure of 131 dormitory residents to low levels of CO. The CO Neuropsychological Screening Battery (CONSB), a series of tests reported by others as useful to identify victims of CO poisoning, was performed on a subset of 46 victims. It was hypothesized that their test scores would improve after treatment with HBO.Methods:Testing was performed both before and after HBO on 35 CO-exposed victims. A control group of 20 students residing on the same college campus, but not involved with the CO incident, also were tested on two separate occasions to assess the ability of the test to identify selectively victims of low-level CO poisoning, as well as to evaluate its validity when administered serially.Results:Both CO-exposed and control subjects demonstrated significant performance improvement when completing the testing for the second time. In addition, the baseline test scores were not significantly different for either the CO-exposed or the control groups. Nonetheless, all CO-exposed victims reported immediate subjective improvement of their symptoms after HBO therapy.Conclusion:These observations and a review of the literature suggest that there might exist a syndrome of subtle neurological disturbances in victims of low-level CO poisoning. Whether this is permanent or might regress spontaneously over time is unknown. As a diagnostic adjunct, the CONSB does not appear to be as useful in low-level CO poisoning.

ABSTRACT   Quality of life is the subjective perception of the individual to the physical, psychological, social, and environmental conditions experienced. The aim of the study was to analyze differences in the physical dimensions of the quality of life of diabetes mellitus patients between providing hyperbaric oxygen therapy 10 days and 5 days. This study used the quasy experiment method with the approach of pre post test with control group design. The population in the study was 882 people with a sample of 14 respondents divided into two groups. 7 respondents in the treatment group and 7 respondents in the control group. Sampling used was consecutive sampling technique. Data were analyzed using Paired t test and Independent t test. The results of the Paired t test statistic in the treatment group had differences in quality of life before and after 10 days of hyperbaric oxygen therapy, while the control group had no difference in quality of life before and after 5 days of hyperbaric oxygen therapy. The independent t test results were different after being given hyperbaric oxygen therapy 10 days and 5 days. It is expected that health workers can be used as a reference source and as a basis for determining nursing intervention in the management of diabetes, especially in the quality of life of diabetic patients.

Before And After

In a double blind, placebo-controlled study to assess the prophylactic effect of hyperbaric oxygen therapy on migraine, 40 patients were randomly assigned to a treatment group receiving three sessions of hyperbaric oxygen, or a control group receiving three hyperbaric air treatments. The patients were instructed to keep a standardized migraine diary for eight weeks before and after the treatment. Thirty-four patients completed the study. Our primary measure of efficacy was the difference between pre- and post-treatment hours of headache per week. The results show a nonsignificant reduction in hours of headache for the hyperbaric oxygen group compared to the control group. Levels of endothelin-1 in venous blood before and after treatment did not reveal any difference between the hyperbaric oxygen and control groups. We conclude that the tested protocol does not show a significant prophylactic effect on migraine and does not influence the level of endothelin-1 in venous blood.

Oxidative Stress Indicators

This study was conducted to explore the effect of hyperbaric oxygen (HBO) therapy combined with virtual reality (VR) training on oxidative stress indicators (OSIs) and inflammatory factors (IFs) in swimming athletes with depression. 88 swimming athletes suffering from depression were grouped into a control group (group C) and a research group (group R). The patients in group C were given HBO therapy, and the group R was given HBO therapy combined with VR training. The Physical Health Questionnaire (PHQ-9) and the Symptom Checklist (SCL-90) were adopted to assess the depression status of patients. The differences between the two groups of serum OSIs and IFs before and after the intervention were compared and analyzed. The results disclosed that the PHQ-9 score and SCL-90 score in group R were not different from those in group C before the intervention, but those in group R were greatly decreased in contrast to group C after the intervention ( P < 0.05 ). Before the intervention, there was no obvious difference in the OSIs and the IFs between the two groups. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) in the two groups were decreased greatly after intervention, and those in the group R were much lower than those in group C ( P < 0.05 ). Compared with the preintervention, the levels of malondialdehyde (MDA) in both groups were reduced observably, and the levels of superoxide dismutase (SOD), nitric oxide (NO), and glutathione peroxidase (GSH-Px) were dramatically increased. The MDA in group R was much lower, while the SOD, NO, and GSH-Px were much higher in contrast to group C ( P < 0.05 ). It indicated that HBO combined with VR training had a good clinical effect for swimming athletes suffering from depression, and it could reduce the oxidative stress and inflammation, thereby helping patients recover quickly.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
