Introduction: Parabolic flights, by producing short periods of weightlessness, closely simulate microgravity. However, they are still expensive, incur a significant logistics support, and occurrence of any adverse events during such simulation is undesirable. The present study was formulated to explore the feasibility of using a human centrifuge for simulation of parabolic flight to study the cardiopulmonary parameters as an alternative ground-based model. Material and Methods: Twelve healthy male volunteers were subjected to simulated parabolic flight, the profile of which involved exposure to 20 repetitions of hypogravity periods (+0.5 Gz), each interposed between periods of hypergravity phases (+2 Gz), using high-performance human centrifuge. Heart rate (HR), respiratory rate (RR), and arterial oxygen saturation (SpO2) were studied during such a simulation and analyzed using one-way repeated measures ANOVA. Motion sickness assessment questionnaire was administered to the participants after the run. They were also asked to rate their subjective feeling of weightlessness experienced during the run. Results: Comparison of HR revealed a significant difference (F = 22.167, P < 0.001) across 20 loops of different gravity phases. Post hoc analysis revealed that the mean HR of hypergravity phases was significantly higher compared with pre-run 1 G values and that of hypogravity phases. Similarly, HR showed a significant difference across pre-run 1 G, 10th and 20th loops of hypogravity phases (F = 5.672, P = 0.01). Post hoc analysis revealed a significant reduction in HR at 20th loop compared to both pre-run 1 G (P = 0.023) and 10th loop (P = 0.042) values. No significant differences were observed in both RR (F = 1.789, P = 0.148) and SpO2 (F = 1.708, P =0.199) across different gravity phases. The mean overall motion sickness score was found to be 23.6%. Participants rated their subjective feeling of weightlessness between 4 and 6 (mode = 5) on a scale of 1–10. Conclusion: It can be concluded from the results that HR increased during hypergravity conditions and reduced during hypogravity conditions, an expected outcome during parabolic flight. The significant reduction in HR during the 20th loop of hypogravity phase compared to 10th loop and pre-run 1 G conditions indicate a possible association with the duration of exposure. The centrifuge simulated parabolic flight profile designed in our study was able to emanate physiological changes similar to those experienced in actual parabolic flight for HR, RR, and SpO2.

Background: The increasing prevalence of SARS-COV-2 infection necessitates further epidemiological studies in the field of this epidemic. Methods: during 66 days (20/02/2020 to 01/06/2020) all patients diagnosed with SARS-COV-2 infection referred to Valiasr Hospital in Arak were monitored. Thus, based on the pre-prepared questionnaire, the information of the mentioned patients was extracted from the Hospital Information System (HIS) by the required formats and after eliminating the incomplete cases, it was aggregated based on coding (to preserve the patients' information). The results were evaluated using spss. v25 software. Results: Out of 535 patients with SARS-COV-2 included in the study, 295 (55%) were male and 240 (45%) were female. Women with a mean age of 61.03 years were significantly (p = 0.009) at a higher age than men with a mean age of 56.59 years. Nearly 60% (304 patients) of patients had a history of underlying disease. Gender comparison of patients with a history of underlying disease infected with SARS-COV-2 infection did not show any significant difference between male and female patients. Comparison of the mean age of the improved and dead patients shows that the mean age of the dead patients with a significant difference (P <0.001) was higher than the improved subjects. This result is also true for people with a history of underlying disease (p<0.0001). The number of patients with arterial oxygen saturation <93% was significantly higher in the group of patients with a history of at least one chronic underlying disease than who did not have any chronic disease (P <0.0001). The mortality rate in ICU patients was significantly higher than those admitted to the normal ward (p < 0.0001). Conclusion: Aging, gender, underlying diseases and arterial oxygen saturation (<93%) at the time of admission have important role in the hospitalization rate, severity of the disease and mortality in patients with COVID-19.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a major adverse effect of cardiac surgery. The early detection of this complication can improve the quality of postoperative care and help prevent this phenomenon. Methods: In this prospective descriptive-analytical study, 148 patients were enrolled, 107 of whom were selected for analysis between February and September 2019 in the Cardiac Surgery Unit of Golestan Hospital, Ahvaz, Iran. Kidney tissue oxygen saturation was measured at multiple definite times during surgery. Hemoglobin, blood urea nitrogen, creatinine, and lactate were measured during and 48 hours after the surgery. Results: Forty-one patients were diagnosed with CSA-AKI according to the KDIGO criteria. Parametric and non-parametric analyses showed no significant difference between the CSA-AKI and non-CSA-AKI groups in the demographic parameters. Repeated measures ANOVA showed no significant difference in parameters, except for BUN. Repeated measures ANOVA showed a significant difference between both groups and time factors (P < 0.001, P = 0.0006, respectively). The ROC curve analyses showed that in a single point of time, the difference in the middle of CPB time from baseline had a high value in the prediction of AKI (AUC: 0.764; CI: 0.57 - 0.951). Conclusions: Kidney saturation monitoring could be considered in cardiac surgery for the rapid detection of CSA-AKI. Although kidney tissue saturation is not correlated directly to the arterial oxygen saturation, the physician and the surgery team can predict the chance of acute kidney injury.

Objective: to compare the time for performance of dry and traditional bed bathing and its effects on transcutaneous arterial oxygen saturation and respiratory rates in critical adult patients. Method: pilot study of a randomized, open, crossover clinical trial, performed with 15 adult critically ill patients. Each patient received a dry and a traditional bed bath. Analysis of variance with repeated measures was used, adopting p-value ≤ 0.05. Results: most patients were male (73.3%), white (66.7%), with a mean age of 69.7 years. The dry bath was faster (20.0 minutes) than the traditional bath (30.0 minutes) (p<0.001). There was no significant difference between the patients’ saturation means between baths (p=0.381), with 94.7% for the dry bath and 95.2% for the traditional bath. During the traditional bath, the patients’ respiratory rate mean was higher (24.2 incursions per minute) and statistically different (p<0.001) from the value obtained for the dry bath (20.5 incursions per minute). Conclusion: the dry bath had a shorter duration than did the traditional bath, resulting in less patient exposure. The traditional bed bath had a negative effect on patients’ respiratory rate, increasing it. Brazilian Registry of Clinical Trials (ReBEC): RBR-5qwkqd

INTRODUCTION: We compared the physiological responses, psychomotor performances, and hypoxia symptoms between 7000 m and 7500 m (23,000 and 24,600 ft) exposure to develop a safer hypoxia training protocol.METHODS: In altitude chamber, 66 male pilots were exposed to 7000 and 7500 m. Heart rate and arterial oxygen saturation were continuously monitored. Psychomotor performance was assessed using the computational task. The hypoxic symptoms were investigated by a questionnaire.RESULTS: The mean duration time of hypoxia was 323.0 56.5 s at 7000 m and 218.2 63.3 s at 7500 m. The 6-min hypoxia training was completed by 57.6% of the pilots and 6.1% of the pilots at 7000 m and at 7500 m, respectively. There were no significant differences in pilots heart rates and psychomotor performance between the two exposures. The Spo2 response at 7500 m was slightly severer than that at 7000 m. During the 7000 m exposure, pilots experienced almost the same symptoms and similar frequency order as those during the 7500 m exposure.CONCLUSIONS: There were concordant symptoms, psychomotor performance, and very similar physiological responses between 7000 m and 7500 m during hypoxia training. The results indicated that 7000-m hypoxia awareness training might be an alternative to 7500-m hypoxia training with lower DCS risk and longer experience time.Wen D, Tu L, Wang G, Gu Z, Shi W, Liu X.

<p><strong>Background</strong>: Although the avoidance of cardiopulmonary bypass during the Fontan procedure has potential advantages, using cardiopulmonary bypass during this procedure has no adverse effects in terms of morbidity and mortality rates. In this study, we assessed the postoperative outcomes of our first 9 patients who have undergone extracardiac Fontan operation by the same surgeon using cardiopulmonary bypass.</p><p><strong>Methods</strong>: Between September 2011 and April 2013,  9 consecutive patients (3 males and 6 females) underwent extra-cardiac Fontan operation. All operations were performed under cardiopulmonary bypass at normothermia by the same surgeon.  The age of patients ranged between 4 and 17 (9.8 ± 4.2) years. Previous operations performed on these patients were modified Blalock-Taussig shunt procedure in 2 patients, bidirectional cavopulmonary shunt operation in 6 patients, and pulmonary arterial banding in 1 patient. Except 2 patients who required intracardiac intervention, cross-clamping was not applied. In all patients, the extracardiac Fontan procedure was carried out by interposing an appropriately sized tube graft between the infe-rior vena cava and right pulmonary artery.</p><p><strong>Results</strong>: The mean intraoperative Fontan pressure and transpulmonary gradient were 12.3 ± 2.5 and 6.9 ± 2.2 mm Hg, respectively. Intraoperative fenestration was not required. There was no mortality and 7 patients were discharged with-out complications. Complications included persistent pleural effusion in 1 patient and a transient neurological event in 1 patient. All patients were weaned off mechanical ventila-tion within 24 hours. The mean arterial oxygen saturation increased from 76.1% ± 5.3% to 93.5% ± 2.2%. All patients were in sinus rhythm postoperatively. Five patients required blood and blood-product transfusions. The mean intensive care unit and hospital stay periods were 2.9 ± 1.7 and 8.2 ±  1.9 days, respectively.</p><p><strong>Conclusions</strong>: The extracardiac Fontan operation per-formed using cardiopulmonary bypass provides satisfactory results in short-term follow-up and is associated with favor-able postoperative hemodynamics and morbidity rates.</p>

Abstract Background The life-threatening haemorrhagic complications of pulmonary arteriovenous malformations (PAVMs) are extremely rare, and only described in isolated cases. This study was designed to comprehensively investigate management of ruptured PAVMs. Methods We retrospectively assessed clinical and imaging data of ruptured PAVMs to summarize incidence, clinical characteristics, and outcomes following embolisation between January 2008 and January 2021. Results Eighteen of 406 (4.4%) patients with PAVMs developed haemorrhagic complications. Twelve of 18 patients were clinically diagnosed with hereditary haemorrhagic telangiectasia (HHT). Haemorrhagic complications occurred with no clear trigger in all cases. Eight of 18 patients (44.4%) were initially misdiagnosed or had undergone early ineffective treatment. 28 lesions were detected, with 89.3% of them located in peripheral lung. Computed tomography angiography (CTA) showed indirect signs to indicate ruptured PAVMs in all cases. Lower haemoglobin concentrations were associated with the diameter of afferent arteries in the ruptured lesions. Successful embolotherapy was achieved in all cases. After embolotherapy, arterial oxygen saturation improved and bleeding was controlled (P < 0.05). The mean follow-up time was 3.2 ± 2.5 years (range, 7 months to 10 years). Conclusions Life threatening haemorrhagic complications of PAVMs are rare, they usually occur without a trigger and can be easily misdiagnosed. HHT and larger size of afferent arteries are major risk factors of these complications. CTA is a useful tool for diagnosis and therapeutic guidance for ruptured PAVMs. Embolotherapy is an effective therapy for this life-threatening complication.

Visual fatigue caused by prolonged work viewing a Visual Display Terminals (VDT) and of work reading a hard-copy were assessed by electromyogram (EMG) waveform and electrooculogram (EOG) waveform in spontaneous blinks as objective criteria, and by questionnaire of subjective feeling, and by task performance. The duration and the amplitude of the EMG of the orbicularis ocular muscle on the right side and the EOG of the vertical direction to the eyelid were measured for 10 subjects who participated in a figure task consisting of the addition of single-digit numbers on a VDT work or a work with a hard-copy. The mean values of the duration and the amplitude of the EMG and the EOG were evaluated by the averaging of 10 waveforms of the spontaneous blinks for all subjects. The time lag from the EMG to the EOG in the process of the generation of spontaneous blinks was also analyzed. These five parameters were evaluated during the work time. The mean values for the duration of the EMG increased gradually during the work time, but the amplitude did not show significant difference between the prework and a work time. There was no significant change of the duration of the EOG, but the mean amplitude of the EOG decreased as the work time progressed, and the time lag significantly extended. The blinks frequency increased relatively when using a VDT. The rate of fluctuation for these parameters was higher during use of a VDT than use of a hard-copy. The time lag at five hours of VDT work was extended by 90% based on the value at the prework. The symptoms of general fatigue and fatigue of the eyes increased linearly during the VDT work for six hours. The results indicated a significant correlation between the objective parameters for the activity of the spontaneous blinks, i.e., duration and amplitude of EMG and EOG, and the time lag between EMG and EOG, and the subjective feeling was recognized in the time course of the task. These experimental results suggested that the parameters regarding the EMG and the EOG for the spontaneous blinks were effective indices for assessing visual fatigue during prolonged VDT work.

Background: Common clinical problems after surgery include nausea, vomiting and ileus that many patients complain of after their surgery. These complications can delay the patient's discharge from hospital. Nowadays, to reduce drug side effects, the use of complementary medicine, including reflexology, has received a great deal of attention. Aim: To compare the effect of hand and foot reflexology massages on the severity of nausea, vomiting and ileus in patients after abdominal surgery. Methods: This is a clinical trial study that was conducted between 2013 and 2015 in the emergency surgical departments of Imam Reza (AS) and Ghaem (AS) hospitals in Mashhad. The samples of this study included 90 women with cholecystitis and appendicitis who met the inclusion criteria. In this study, patients were randomly divided into 3 groups of hand reflexology massage, foot reflexology massage and control. To check the digestive status, gastrointestinal sounds were checked every hour using a clinical stethoscope. Also, information on gas and feces elimination was collected and recorded every hour. The intervention was performed 1 and 12 hours after the surgery. In both groups of hands and foot reflexology massages, after general massage of the hands and feet, the areas related to the abdominal distension and removal of the ileus were pressed. It should be noted that, the duration of massage for each person was 10 minutes (20 minutes in total). Data were analyzed by SPSS software version 16 using Chi-square, Fisher’s exact test, two-way ANOVA, Kruskal-Wallis test and repeated measures ANOVA. Results: There was no statistically significant difference in the mean score of severity of nausea before the intervention between the three groups (p = 0.90), but after the intervention a significant difference was observed in the mean score of severity of nausea between the three groups (p=0.002). Also, the result of ANOVA test with repeated measure showed a statistically significant difference in the mean score of nausea by group and stage (p<0.001). There was also no statistically significant difference in the frequency of vomiting severity between the three groups after the intervention. However, at 4 and 24 hours after the intervention, a statistically significant difference was observed between the three groups in that regard. Conclusion: The results showed that both types of hand and foot reflexology massage has positive effects on nausea and return of gastrointestinal movements, so nurses can use reflexology as a non-pharmacological and complementary method to reduce the severity of nausea and return gastrointestinal movements in postoperative patients. Since the reflexology had little or no effect on the severity of vomiting and the acceleration of gastrointestinal movements in patients, further studies in this area are recommended.

The purpose of this study was to compare chemoresponses following two different intermittent hypoxia (IH) protocols in humans. Ten men underwent two 7-day courses of poikilocapnic IH. The long-duration IH (LDIH) protocol consisted of daily 60-min exposures to normobaric 12% O2. The short-duration IH (SDIH) protocol comprised twelve 5-min bouts of 12% O2, separated by 5-min bouts of room air, daily. Isocapnic hypoxic ventilatory response (HVR) was measured daily during the protocol and 1 and 7 days following. Hypercapnic ventilatory response (HCVR) and CO2 threshold and sensitivity (by the modified Read rebreathing technique) were measured on days 1, 8, and 14. Following 7 days of IH, the mean HVR was significantly increased from 0.47 ± 0.07 and 0.47 ± 0.08 to 0.70 ± 0.06 and 0.79 ± 0.06 l·min−1·%SaO2−1 (LDIH and SDIH, respectively), where %SaO2 is percent arterial oxygen saturation. The increase in HVR reached a plateau after the third day. One week post-IH, HVR values were unchanged from baseline. HCVR increased from 3.0 ± 0.4 to 4.0 ± 0.5 l·min−1·mmHg−1. In both the hyperoxic and hypoxic modified Read rebreathing tests, the slope of the CO2/ventilation plot was unchanged by either intervention, but the CO2/ventilation curve shifted to the left following IH. There were no correlations between the changes in response to hypoxia and hypercapnia. There were no significant differences between the two IH protocols for any measures, indicating that comparable changes in chemoreflex control occur with either protocol. These results also suggest that the two methods of measuring CO2 response are not completely concordant and that the changes in CO2 control do not correlate with the increase in the HVR.

Purpose During the ART era, persistent immune activation remains a significant challenge in people living with HIV (PLWH). Microbial translocation play an essential role in this setting. Probiotics have several immunological benefits which can reverse this process. The purpose of this paper is to investigate the safety and efficacy of probiotics on CD4 counts among Iranian PLWH. Design/methodology/approach In total, 50 PLWH with CD4 counts above 350 cells/mm3 did not receive ART participated in a randomized, double-blind trial and underwent 24 weeks of treatment with either LactoCare® or placebo twice daily. CD4 counts of the patients were measured at baseline, 12 weeks and 24 later in the two groups. Side effects were measured monthly using a specific checklist. Findings The mean CD4 count of the patients showed a significant difference between the two groups after six months. Through six months follow up, the mean CD4 count of the patients showed a significant reduction as compared to the baseline in the placebo group; however, it did not show a significant difference in the probiotic group. Repeated Measures Anova test showed a significant effect for time × treatment interaction on the CD4 count during the trial course. No significant difference between the two groups concerning adverse events was reported. Originality/value It seems the use of probiotics in PLWH with a CD4 count above 350 cells/mm3 who are not receiving antiretroviral drugs is safe and can reduce the devastating process of CD4+ T cells in these patients.
