Few studies have compared intraoperative oxygenation and perioperative outcomes between non-intubated video-assisted thoracic surgery (NIVATS) with supraglottic airway devices (SADs) and NIVATS with high flow nasal oxygenation (HFNO). The aim of this retrospective study was to compare the intraoperative desaturation rate and postoperative outcomes between NIVATS with SADs and NIVATS with HFNO.Data regarding NIVATS performed for lung cancer from January 2020 to December 2021 were collected. Intraoperative anesthetic results, post-anesthetic adverse effects, and surgical outcomes for patients who received SAD or HFNO were analyzed using propensity score-matched and unmatched analysis.In total, 199 patients with i-gel™ and 95 patients with HFNO were included. Significantly more female patients (91.6 vs. 82.4%, p = 0.0378) and fewer wedge resections (78.9 vs. 85.4%, p = 0.0258) were observed in the HFNO group. Among 250 patients who underwent NIVATS wedge resections under total intravenous anesthesia, those who received HFNO had a significantly higher desaturation event rate (19.8% vs. 7.9% in i-gel™ group; p = 0.0063), lower nadir SPOThe rate of SAD use in NIVATS was twice the rate of HFNO use, especially for wedge resections. There is uncertain airway patency and limited flow through HFNO during one-lung ventilation, whereas SADs like i-gel™ presented a significantly less intraoperative desaturation rate over time and similar postoperative outcomes.

Gu Sui Bu (GSB), the dried rhizome of Drynaria fortunei J. Sm., is widely used in traditional Chinese medicine for treating fractures and osteoporosis. Although glucocorticoids are widely prescribed in modern medicine, the efficacy of GSB in treating glucocorticoid-induced osteoporosis (GIOP) remains unclear.GIOP is one of the most prevalent forms of osteoporosis and increases the risk of fracture, which can cause severe complications in elderly people. Safe, efficacious, and cost-effective treatment options for GIOP are thus warranted. The present study investigated the efficacy and mechanism of GSB for treating GIOP.We established an efficient and robust in vivo GIOP model by optimizing zebrafish larvae rearing conditions and the dose and duration of dexamethasone treatment. Bone calcification was evaluated through calcein staining. To quantify the degree of vertebral mineralization in the larvae, we developed a scoring system based on the rate of vertebral calcification; this system reduced quantification errors among individual zebrafish caused by inconsistencies in staining or imaging parameters. Quantitative real-time polymerase chain reaction was used to access the expression levels of genes essential to the differentiation and function of bone cells. High-performance liquid chromatography was employed to identify naringin in the GSB extract.GSB significantly reversed the dexamethasone-induced calcification delay in zebrafish larvae. GSB enhanced osteoblast activity by increasing the expression of collagen I, osteopontin, and osteonectin and repressed bone resorption by decreasing the expression of matrix metalloproteinases (mmps), including mmp9 and mmp13a. We also identified naringin as one of the constituents of GSB responsible for the herbal extract's anti-GIOP activity.Using the in vivo zebrafish GIOP model that we established, the efficacy of traditional Chinese medicines in treating GIOP could be systematically investigated. GSB has an osteogenic effect and may thus be an efficacious and cost-effective treatment option for GIOP. Notably, bone resorption activity was found to be retained after GSB treatment, which would be beneficial for maintaining normal bone remodeling.

The aim of this study is to describe the technique of pulmonary expansion by suction control from a surgical wound during nonintubated uniportal video-assisted thoracic surgery. Five patients developed oxygen desaturation intraoperatively even with facial mask ventilation. Oxygenation was completed after 3 minutes with the suction technique through the uniportal wound. All the patients underwent the operation under spontaneous ventilation, without conversion to endotracheal intubation. The suction ventilation technique can provide an alternative solution during deoxygenation conditions of nonintubated video-assisted thoracic surgery.

This study aimed to evaluate the effects of motor imagery (MI) on walking function and balance in patients after stroke.Related randomized controlled trials (RCTs) were searched in 12 electronic databases (Cochrane Central Register of Controlled Trials, PubMed, Science Direct, Web of Science, Allied and Complementary Medicine, Embase, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, WanFang, and VIP) from inception to November 30, 2016, and Review Manager 5.3 was used for meta-analysis. References listed in included papers and other related systematic reviews on MI were also screened for further consideration.A total of 17 studies were included. When compared with "routine methods of treatment or training", meta-analyses showed that MI was more effective in improving walking abilities (standardized mean difference [SMD] = 0.69, random effect model, 95% confidence interval [CI] = 0.38 to 1.00, P 0.0001) and motor function in stroke patients (SMD = 0.84, random effect model, 95% CI = 0.45 to 1.22, P 0.0001), but no statistical difference was noted in balance (SMD = 0.81, random effect model, 95% CI = -0.03 to 1.65, P = 0.06). Statistically significant improvement in walking abilities was noted at short-term (0 to six weeks) (SMD = 0.83, fixed effect model, 95% CI = 0.24 to 1.42, P = 0.006) and long-term (≥six weeks) assessments (SMD = 0.45, fixed effect model, 95% CI = 0.25 to 0.64, P 0.00001). Subgroup analyses suggested that MI had a positive effect on balance with short-term duration (0 to six weeks) (SMD = 4.67, fixed effect model, 95% CI = 2.89 to 6.46, P 0.00001), but failed to improve balance (SMD = 0.82, random effect model, 95% CI = -0.27 to 1.90, P = 0.14) with long-term (≥six weeks) duration.MI appears to be a beneficial intervention for stroke rehabilitation. Nonetheless, existing evidence regarding the effects of MI in patients after stroke remains inconclusive because of significantly statistical heterogeneity and methodological flaws identified in the included studies. More large-scale and rigorously designed RCTs in future research with sufficient follow-up periods are needed to provide more reliable evidence on the effects of MI in post-stroke patients.

This study compared the cardiac output (CO) obtained from PiCCO with that obtained from the noninvasive NICOM method.Twenty-one cirrhotic patients receiving liver transplantation were enrolled. During the operation, their CO was measured by the PiCCO system via the thermodilution method as the standard and by the NICOM method. Two parameters including cardiac index (CI) and stroke volume index (SVI) were collected simultaneously at three phases during the surgery including the dissection phase (T1), the anhepatic phase (T2), and the reperfusion phase (T3). Correlation, Bland and Altman methods, and linear mixed model were used to evaluate the monitoring ability of both systems.Poor correlation was noted between the data measured by NICOM and PiCCO; the correlation coefficients for CI and SVI measured between the two systems were 0.32 and 0.39, respectively. Bland and Altman analysis showed the percentage error of CI as 63.7%, and that of SVI as 66.6% for NICOM compared to PiCCO. Using the linear mixed model, the CI and SVI measured using NICOM were significantly higher than those using PiCCO (estimated regression coefficient 0.92 and 10.77, both p 0.001). Mixed model analysis showed no differences between the trends of CI and SVI measured by the two methods.NICOM provided a comparable CI and SVI trend when compared to the gold standard PiCCO, but it raises concerns as an effective CO monitor because of its tendency to overestimate CI and SVI especially during the state of high cardiac output.

Background Perioperative psychological distress is associated with preoperative anxiety, depression, and postoperative pain. Mirtazapine is effective as an antidepressant, anxiolytic agent, and sleep enhancer. Moreover, mirtazapine can be made as orodispersible tablets with a fast onset for patients in nil per os status. This study is to determine whether mirtazapine can help psychologically distressed patients reduce perioperative anxiety, depression, and postoperative pain. Materials and methods Patients with preoperative psychological distress, undergoing major abdominal surgery, were inquired and assigned to two groups according to their own choice. In the treatment group, patients could choose to take orodispersible mirtazapine 30 mg at each night from Preoperative Day 0 to Postoperative Day 3. There was no other intervention in the nontreatment group. Hospital Anxiety and Depression Scale (HADS), Athens Insomnia Scale (AIS), and pain scores were accessed on the day before operation (Day 0), and on the 1 st day (Day 2) and 3 rd day (Day 4) after operation. We compared the HADS, AIS, and pain scores, and morphine consumptions between the two groups on a daily basis. Marginal regression models were fitted to our correlated longitudinal data alone with the generalized estimating equations method to estimate the population average effects of time-varying mirtazapine usage on the mean values of HADS, AIS, and pain scores, and daily morphine consumptions. Results From September 2007 to December 2008, 86 patients agreed to be enrolled and 79 of them completed the study. Propensity scores and multivariate analysis showed that mirtazapine reduced HADS scores of patients in 2 days. Trial results indicated that mirtazapine lowered the AIS day index and tended to decrease night index as well. Mirtazapine may reduce patients' morphine consumption, but this effect was not statistically significant ( p = 0.2). Conclusion Mirtazapine helps reduce anxiety, depression, and insomnia scores for patients with perioperative psychological distress.

Weak opioid combined with acetaminophen (APAP) has been proven to provide better analgesic efficacy and cause fewer complications than either drug alone. However, there are questions about whether different opioids, tramadol and propoxyphene, provide similar efficacy or safety. Thus, we investigated Ultracet (37.5 mg tramadol/325 mg APAP) and Depain-X (65 mg propoxyphene/650 mg APAP). The primary aims of this study were to compare the analgesic efficacy and adverse effects of single-dose oral Ultracet versus Depain-X in acute postoperative pain.This was a randomized, open-label, active-controlled parallel study on patients with postsurgical pain. Sixty patients who sustained moderate postsurgical pain (visual analog scale(3)3 cm) after undergoing implantation of venous access were randomized to two groups to receive either Ultracetor Depain-X for postoperative analgesia. Assessment items included pain intensity and pain relief ratings at the first 4 hours, and adverse events.There were initially 107 patients who were enrolled in this trial, but up to 45 (42.1%) of them were withdrawn during the study. In these 62 patients who complied with treatment (Ultracet: Depain-X = 29: 33), pain relief scale indicated that Ultracet could provide a better analgesic effect than Depain-X provided at 1 hour (p0.05). At 4 hours, the pain score in the Ultracet group was significantly lower than that in the Depain-X group (p0.05). Adverse events, such as drowsiness, dizziness, and skin itching did not differ in both groups.Among patients with mild to moderate postoperative wound pain, single-dose Ultracet can provide slightly better analgesic efficacy than Depain-X in terms of onset and duration. Depain-X is no longer marketed in Europe, America, Taiwan and other countries, therefore, Ultracet can serve as a good substitute for treating postoperative pain.

This study investigated how shallow processing (complexity rating), deep processing (pleasantness rating), and semantic generation (translating from English) of Chinese words affects conscious memory (CM) and unconscious memory (UM) of the words with three implicit tests: word association, word identification, and word-stem completion. A metacognition-based dissociation procedure was used to estimate the two forms of memory for each test. Except for the shallow condition preceding the word-association test, all three study conditions produced a positive effect on the estimate of CM. The estimate of UM did not benefit from any of the study conditions in the word-association test, it benefited from the shallow and deep conditions but did not benefit from the generation condition in the stem-completion test, and it benefited from the shallow condition but did not benefit from the deep and generation conditions in the word-identification test. Implications of these results for CM and UM operations are discussed.
