RESUMO

Apoptosis is a physiological cell death phenomenon, representing one of the fundamental physiological mechanisms for maintaining homeostasis in living organisms. Previous studies have observed typical apoptotic features in Carassius auratus gibelio caudal fin cell (GiCF) infected with Cyprinid herpesvirus 2 (CyHV-2), and found a significant up-regulation of ccBAX expression in these infected cells. However, the specific apoptotic mechanism involved remains unclear. In this study, we utilized the GiCF cell line to investigate the apoptotic mechanism during CyHV-2 infection. Immunofluorescence staining revealed translocation of ccBAX into mitochondria upon CyHV-2 infection. Flow cytometry analysis demonstrated that overexpression of ccBAX expedited virus-induced apoptosis, characterized by heightened mitochondrial depolarization, increased transcriptional levels of Cytochrome c (Cyto c) in both the cytoplasm and mitochondria, and augmented Caspase 3/7 enzyme activity. Bax inhibitor peptide V5 (BIP-V5), an inhibitor interfering with the function of Bax proteins, inhibited Bax-mediated apoptotic events through the mitochondrial pathway and attenuated apoptosis induced by CyHV-2. In this study, it was identified for the first time that CyHV-2 induces apoptosis via the mitochondrial pathway in GiCF cells, bridging an important gap in our understanding regarding cell death mechanisms induced by herpesvirus infections in fish species. These findings provide a theoretical basis for comprehending viral apoptotic regulation mechanisms and the prevention and control of cellular pathologies caused by CyHV-2 infection.

RESUMO

Aiming at the lack of quantitative evaluation methods in clinical diagnosis of lung cancer, a classification and prediction model of lung cancer based on Support Vector Machine (SVM) was constructed by using radiomics method. Firstly, the definition and processing flow of radiomics were introduced. The experimental samples were selected from 816 lung cancer patients on LIDC. Firstly, ROI was extracted by central pooling convolution neural network segmentation method. Then, Pyradiomics and FSelector feature selection models were used to extract features and reduce dimension. Finally, SVM was used to construct the classification and prediction model of lung tumors. The predictive accuracy of the model is 80.4% for the classification of benign and malignant pulmonary nodules larger than 5 mm, and the value of the area under the curve (AUC) is 0.792. This indicates that the SVM classifier model can accurately distinguish benign and malignant pulmonary nodules larger than 5 mm.

RESUMO

BACKGROUND: To investigate the optimal dose of pretreated-dexmedetomidine in fentanyl-induced cough (FIC) suppression. METHODS: Patients of 180 undergoing elective surgery with general anesthesia, aged 18-65 years, BMI 18.5-30 kg/m2, ASA I or II, were equally randomized into four groups (n = 45) to receive intravenous pretreatment of dexmedetomidine with 0 (group 1), 0.3 (group 2), 0.6 (group 3) and 0.9 (group 4) mcg/kg over 10 mins, respectively. After the pretreatment, all patients were given a 5-s intravenous injection of fentanyl 4 mcg/kg. The symptoms of irritating cough including the severity and onset time were recorded for 1 min after fentanyl injection. General anesthesia induction was completed with midazolam, propofol and cisatracurium, then endotracheal tube or laryngeal mask was inserted and connected to an anesthesia machine. MAP, HR and SpO2 at the beginning of pretreatment (T0), 3 min (T1), 6 min (T2), 9 min (T3) and 12 min (T4) after the beginning of pretreatment were recorded. Side effects of dexmedetomidine, such as bradycardia, hypertension, hypotension, and respiratory depression were also recorded during the course. RESULTS: Totally 168 patients completed the study. The incidences of cough were 52.4, 42.9, 11.9, and 14.3% in groups 1, 2, 3, and 4, respectively, with no significant differences between groups 1 and 2 (P > 0.05) and between groups 3 and 4 (P > 0.05). The incidence and severity of cough in groups 3 and 4 were significantly lower than those in groups 1 and 2 (P < 0.05). Compared to T0, HR at T2 (P < 0.05), T3 (P < 0.01), and T4 (P < 0.01) decreased significantly and MAP at T4 decreased significantly (P < 0.05) in group 4. Bradycardia occurred in 1 case and respiratory depression occurred in 1 case in group 4. Compared to group 1, the onset time of cough in the other 3 groups were delayed significantly (P < 0.05). CONCLUSION: Pretreated dexmedetomidine 0.6 mcg/kg blous intravenous infusion over 10 mins could reduce FIC effectively without side effects. TRIAL REGISTRATION: This study was registered in ClinicalTrials.gov (NCT03126422), April 13, 2017.

RESUMO

Nowadays, two-factor data security protection has become a research hotspot in smart ocean management. With the increasing popularity of smart ocean management, how to achieve the two-factor protection of public data resources in smart ocean management is a serious problem to be tackled. Furthermore, how to achieve both security and revocation is also a challenge for two-factor protection. In this paper, we propose a two-factor-based protection scheme with factor revocation in smart ocean management. The proposed scheme allows data owners (DOs) to send encrypted messages to users through a shipboard server (SS). The DOs are required to formulate access policy and perform attribute-based encryption on messages. In order to decrypt, the users need to possess two factors. The first factor is the user's secret key. The second factor is security equipment, which is a sensor card in smart ocean system. The ciphertext can be decrypted if and only if the user gathers the key and the security equipment at the same time. What is more, once the security equipment is lost, the equipment can be revoked and a new one is redistributed to the users. The theoretical analysis and experiment results indeed indicate the security, efficiency, and practicality of our scheme.

RESUMO

Cytosine methylation at CG sites ((m)CG) plays critical roles in development, epigenetic inheritance, and genome stability in mammals and plants. In the dicot model plant Arabidopsis thaliana, methyltransferase 1 (MET1), a principal CG methylase, functions to maintain (m)CG during DNA replication, with its null mutation resulting in global hypomethylation and pleiotropic developmental defects. Null mutation of a critical CG methylase has not been characterized at a whole-genome level in other higher eukaryotes, leaving the generality of the Arabidopsis findings largely speculative. Rice is a model plant of monocots, to which many of our important crops belong. Here we have characterized a null mutant of OsMet1-2, the major CG methylase in rice. We found that seeds homozygous for OsMet1-2 gene mutation (OsMET1-2(-/-)), which directly segregated from normal heterozygote plants (OsMET1-2(+/-)), were seriously maldeveloped, and all germinated seedlings underwent swift necrotic death. Compared with wild type, genome-wide loss of (m)CG occurred in the mutant methylome, which was accompanied by a plethora of quantitative molecular phenotypes including dysregulated expression of diverse protein-coding genes, activation and repression of transposable elements, and altered small RNA profiles. Our results have revealed conservation but also distinct functional differences in CG methylases between rice and Arabidopsis.

RESUMO

Two yeast enhanced green fluorescence protein (yEGFP) yeast reporter vectors, pR1558-yEGFP and pR406-yEGFP, which are regulated by two RAD54 promoters containing 406-bp and 1558-bp DNA sequences, respectively, were constructed using molecular biological techniques and transformed into yeast for the screening of genotoxins. The constructed biosensors were named W303-1A/R1558-yEGFP and W303-1A/R406-yEGFP. To quantify biosensor performance, both transformed yeast cells were exposed to multiple doses of genotoxins including methylmethane sulfonate (MMS; a DNA alkylating agent), 4-nitroquinoline-N-oxide (4-NQO; a DNA cleavage agent), 5-fluorouracil (5-Fu; an inhibitor of polymerases and topoisomerases) and colchicine and canavanine (affecting other biochemical activities). The yeast bioassay performance was analyzed using fluorescence-activated cell sorting (FACS) and Multi-Mode Reader in a 96-well black microplate. The observed W303-1A/R1558-yEGFP dose-effect relationship was more obvious and the maximum inductions were 5.96-fold (MMS), 2.19-fold (4-NQO) and 2.71-fold (5-Fu); the corresponding values for W303-1A/R406-yEGFP were 2.53-, 1.50- and 1.91-fold, respectively. It is suggested that it is best to select the entire RAD54 promoter when constructing recombinant yeast cells for screening mutagens.

RESUMO

Two vectors were used to construct the recombinant gene yeast cell that can be used to bioassay of the pollution of tetracycline antibiotics in the environment.In the expression vector,the GPD(glyceraldehyde-3-phosphate dehydrogenase)promoter was used to drive the gene expression of tetracycline repressor protein(TR)fused with V5 antigen epitope gene,while in the reporter vector,the tetracycline response element(TRE)was used to regulate Lac Z report gene expression.The specificity and the sensitivity of the recombinant gene yeast cell were evaluated respectively by different concentrations of tetracycline antibiotics and non-tetracycline antibiotics.The results showed that there were significant dose effect relationships between the tetracycline antibiotics and the yeast cells,while non-tetracycline antibiotics showed no dose effect relationships with this biosensor.It is illustrated that the recombinant yeast cells can be used to monitor the tetracycline antibiotic pollution on the environment.

RESUMO

BACKGROUND AND OBJECTIVE: A correlation between neutrophil extracellular traps (NETs) and ischemic stroke (IS) has been hypothesized, but the results of relevant studies remain controversial. The purpose was to determine whether NETs have an impact on ischemic stroke. METHODS: The studies on the correlation between NETs and IS were retrieved from CNKI, Wanfang Data, VIP, CBM, PubMed, Web of Science, Embase, and Cochrane databases by computer from the start of the database to December 2022. The study adhered to PRISMA guidelines. The PICOS model was used to create inclusion criteria. Two researchers screened the literature and extracted the relevant data. The quality of the included studies was evaluated using the NOS and the 11 items recommended by the AHRQ, and meta-analysis was completed using Stata 15.1 software. RESULTS: The researchers included 752 patients in 7 studies (4 case-control studies and 3 cross-sectional studies). The meta-analysis found NETs are positively associated with the severity of IS at the time of onset [r(95% CI) = 0.31(0.24, 0.38), P < 0.001]. NETs are positively associated with a worse prognosis of IS [r(95% CI) = 0.34(0.13, 0.53), P = 0.003]. CONCLUSION: The presence of NETs is positively related to the severity and prognosis of IS. Higher levels of NETs indicate a more severe disease and a poorer prognosis. Because the number and quality of included studies are limited, the above results must be supported by further high-quality studies.

RESUMO

Dysphagia has emerged as a serious health issue facing contemporary society. Consuming thickened liquids is an effective approach for improving the swallowing safety for dysphagia patients. The thickening effect of chia seed gum (CSG), a novel thickener, in different dispersing media (water, orange juice, and skim milk) was investigated. Moreover, the potential application of CSG for dysphagia management was evaluated by comparison with xanthan gum (XG) and guar gum (GG). The thickened liquids prepared with 0.4 %-1.2 % (w/v) CSG, XG, and GG could be classified into levels 1-4, 2-4, and 1-3, respectively, according to the International Dysphagia Diet Standardization Initiative (IDDSI) framework. All the thickened liquids displayed shear-thinning characteristics that facilitated safe swallowing. The viscosities (η50) of CSG dissolved in water (0.202-1.027 Pa·s) were significantly greater than those of CSG dissolved in orange juice (0.070-0.690 Pa·s) and skim milk (0.081-0.739 Pa·s), indicating that CSG had a greater thickening effect in water than in orange juice and skim milk. Compared with those prepared with GG, the thickened liquids prepared with CSG and XG exhibited greater viscoelasticity, better water-holding capacity, and more compact networks. The findings suggested that CSG can be used as a potential thickener for thickening liquid foods to manage dysphagia.

RESUMO

Wearable humidity sensors are attracting strong attention as they allow for real-time and continuous monitoring of important physiological information by enabling activity tracking as well as air quality assessment. Amongst 2Dimensional (2D) materials, graphene oxide (GO) is very attractive for humidity sensing due to its tuneable surface chemistry, high surface area, processability in water, and easy integration onto flexible substrates. However, strong hysteresis, low sensitivity, and cross-sensitivity issues limit the use of GO in practical applications, where continuous monitoring is preferred. Herein, a wearable and wireless impedance-based humidity sensor made with pyrene-functionalized hexagonal boron nitride (h-BN) nanosheets is demonstrated. The device shows enhanced sensitivity towards relative humidity (RH) (>1010 Ohms/%RH in the range from 5% to 100% RH), fast response (0.1 ms), no appreciable hysteresis, and no cross-sensitivity with temperature in the range of 25-60 °C. The h-BN-based sensor is able to monitor the whole breathing cycle process of exhaling and inhaling, hence enabling to record in real-time the subtlest changes of respiratory signals associated with different daily activities as well as various symptoms of flu, without requiring any direct contact with the individual.

RESUMO

BACKGROUND: To provide high-quality evidence for extracorporeal shock wave therapy (ESWT) for low back pain (LBP). METHODS: A computerized search screened trials of ESWT for LBP, and the time range was from the establishment of databases to August 2023, including CNKI, CBMdisc, Wanfang Data, VIP, PubMed, Web of Science, Embase, and Cochrane databases. The outcomes were extracted, including patients' pain, physical and psychological conditions, and adverse reactions. Meta-analysis was completed using Revman 5.4 and Stata 15 software, and GRADEpro software quantitated rate the evidence and assigned a recommendation strength. RESULTS: This meta-analysis included 22 studies involving 1749 patients. After treatment, patients in the ESWT group had lower scores in the visual analog scale (VAS) (mean difference [MD] = -1.14, 95% confidence interval [CI] (-1.47, -0.80), P < .00001), Oswestry disability index (ODI) [MD = -6.01, 95%CI (-7.97, -4.05), P < .00001], and Beck depression inventory [MD = -3.89, 95%CI (-6.59, -1.20), P = .005]; finger-floor distance [MD = -3.71, 95%CI (-5.26, -2.17), P < .00001] was shorter; Japanese orthopedic association scores [MD = 3.20, 95%CI (1.56, 4.85), P = .0001] were higher; at the 3-month follow-up, the VAS [MD = -1.29, 95%CI (-2.39, -0.19), P = .02] and ODI [MD = -5.95, 95%CI (-10.06, -1.84), P = .005] remained lower; adverse reactions [odds ratio = 0.19, 95%CI (0.07, 0.52), P = .001] were less, and the valid cases [odds ratio = 3.84, 95%CI (2.47, 5.96), P < .00001] were more. Sensitivity analyses revealed that the results were stable; Egger test found no publication bias in VAS (P = .270) and valid cases (P = .747); the trim and fill analysis tested the robustness of ODI scores due to the publication bias (P = .029), and the effect sizes before and after the trim and fill were consistent, which means the result was robust. CONCLUSION: ESWT for LBP has efficacy and safety in improving pain, dysfunction, and psychological conditions compared to other therapies. ESWT has shown advantages in terms of long-term efficacy. Randomized controlled trials with larger sample sizes and more objective outcomes are required.

RESUMO

Automation systems are soaring due to the innovation of artificial intelligence (AI) technologies. In this paper, we mainly concentrate on the security and efficiency of data transmission in AI-based automation systems, especially, for data sharing in a group manner in distributed networks. To this end, an authenticated group key agreement protocol is proposed for secure data transmission in AI-based automation systems. In order to release the computational overhead of distributed nodes, a semi-trusted authority (STA) is introduced to enable precomputation operations. Moreover, to overcome the predominantly distributed denial of service (DDoS) attack, a dynamic batch verification mechanism is devised. The presented dynamic batch verification mechanism guarantees that the proposed protocol can be run properly among legitimate nodes regardless of the existence of nodes who suffered from the DDoS attack. Finally, the session key security of the proposed protocol is proved and the performance is evaluated.

RESUMO

Thin films of gallium-doped zinc oxide (GZO), with a thickness of around fifty nanometers were deposited on bio-based poly(ethylene furanoate) (PEF) substrates by radio-frequency sputtering. By optimizing the Ga concentration in the target, the optics, water vapor barrier and antibacterial properties of PEF/GZO composite films can be adjusted. The highest visible light transmittance of the samples was around 85.1%. Furthermore, by introducing some GZO films with typical concentrations, the water vapor barrier and antibacterial properties of PEF films were improved. The optimized water vapor permeability of PEF/GZO composite film was 5.3 × 10-12 g·m/m2·s·Pa, and the highest antibacterial rate can reach 99.85% after 4 h. By XPS analysis, the antibacterial mechanism in the samples is envisaged to be mainly due cytotoxicity of Ga ions. The above results indicate that PEF/GZO films have great potential in the field of antibacterial food packaging.

RESUMO

Objective: Clinical research has shown that local injections for carpal tunnel syndrome reduce the symptoms of patients and enhance their quality of life considerably. However, there are several therapy options, and the optimal choice of regimen remains uncertain. Therefore, we comprehensively evaluated the variations in clinical efficacy and safety of several medications for treating carpal tunnel syndrome. Methods: Computer searches of Embase, PubMed, Cochrane Library, and Web of Science databases were used to collect articles of randomized controlled trials on local injections for treating carpal tunnel syndrome from database creation till 10 June 2023. Two researchers independently screened the literature, extracted information, evaluated the risk of bias in the included studies, and performed network Meta-analysis using Stata 17.0 software. Drug efficacy was assessed using symptom severity/function and pain intensity. Surface under the cumulative ranking curve (SUCRA) ranking was used to determine the advantage of each therapy. Results: We included 26 randomized controlled trials with 1896 wrists involving 12 interventions, such as local injections of corticosteroids, platelet-rich plasma, 5% dextrose, progesterone, and hyaluronidase. The results of the network meta-analysis showed the following: (i) symptom severity: at the 3-month follow-up, D5W combined with splinting (SUCRA = 95%) ranked first, and hyaluronidase (SUCRA = 89.6%) at 6 months; (ii) functional severity: either at the 3-month follow-up (SUCRA = 89.5%) or 6 months (SUCRA = 83.6%), iii) pain intensity: 5% dextrose in water combined with splinting was the most effective at the 3-month (SUCRA = 85%) and 6-month (SUCRA = 87.6%) follow-up. Conclusion: Considering the combination of symptoms/function and pain intensity, combining 5% dextrose in water with splinting is probably the treatment of choice for patients with carpal tunnel syndrome. It is more effective than glucocorticoids and no adverse effects have been observed. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/, identifier CRD42022370525.

RESUMO

Background: Depression is a common mental illness that is widely recognized by its lack of pleasure, fatigue, low mood, and, in severe cases, even suicidal tendencies. Photobiomodulation (PBM) is a non-invasive neuromodulation technique that could treat patients with mood disorders such as depression. Methods: A systematic search of ten databases, including randomized controlled trials (RCTs) for depression, was conducted from the time of library construction to September 25, 2023. The primary outcome was depression. The secondary outcome was sleep. Meta-analysis was performed using RevMan (version 5.4) and Stata (version 14.0). Subgroup analyses were performed to identify sources of heterogeneity. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: Three thousand two hundred and sixty-five studies were retrieved from the database and screened for inclusion in eleven trials. The forest plot results demonstrated that PBM alleviated depression (SMD = -0.55, 95% CI [-0.75, -0.35], I2 = 46%). But it is not statistically significant for patients' sleep outcomes (SMD = -0.82, 95% CI [-2.41, 0.77], I2 = 0%, p > 0.05). Subgroup analysis showed that s-PBM was superior to t-PBM in relieving symptoms of depression. The best improvement for t-PBM was achieved using a wavelength of 823 nm, fluence of 10-100 J/cm2, irradiance of 50-100 mW/cm2, irradiance time of 30 min, treatment frequency < 3/week, and number of treatments >15 times. The best improvement for s-PBM was achieved using a wavelength of 808 nm, fluence ≤1 J/cm2, irradiance of 50-100 mW/cm2, irradiance time ≤ 5 min, treatment frequency ≥ 3/week, number of treatments >15 times. All results had evidence quality that was either moderate or very low, and there was no bias in publication. Conclusion: We conclude that PBM is effective in reducing depression symptoms in patients. However, the current number of studies is small, and further studies are needed to extend the current analysis results.

RESUMO

KEY MESSAGE : We show for the first time that intraspecific crossing may impact mobility of the prominent endogenous retrotransposon Tos17 under tissue culture conditions in rice. Tos17, an endogenous copia retrotransposon of rice, is transpositionally active in tissue culture. To study whether there exists fundamental genotypic difference in the tissue culture-induced mobility of Tos17, and if so, whether the difference is under genetic and/or epigenetic control, we conducted this investigation. We show that dramatic difference in tissue culture-induced Tos17 mobility exists among different rice pure-line cultivars sharing the same maternal parent: of the three lines studied that harbor Tos17, two showed mobilization of Tos17, which accrued in proportion to subculture duration, while the third line showed total quiescence (immobility) of the element and the fourth line did not contain the element. In reciprocal F1 hybrids between Tos17-mobile and -immobile (or absence) parental lines, immobility was dominant over mobility. In reciprocal F1 hybrids between both Tos17-mobile parental lines, an additive or synergistic effect on mobility of the element was noticed. In both types of reciprocal F1 hybrids, clear difference in the extent of Tos17 mobility was noted between crossing directions. Given that all lines share the same maternal parent, this observation indicates the existence of epigenetic parent-of-origin effect. We conclude that the tissue culture-induced mobility of Tos17 in rice is under complex genetic and epigenetic control, which can be either enhanced or repressed by intraspecific genetic crossing.

RESUMO

Objective: To analyze the relationship between effective distance and epidemic spread trajectory and between arrival time and scale based on the COVID-19 data outbreak in Wuhan and thus to improve the prediction ability of the spread of infectious disease. Methods: Up to January 28, 2020, the reporting date, the onset date, and the cumulative number of confirmed cases of COVID-19 in each province and city were collected. Baidu migration data was used to calculate the effective distance from Wuhan city to other regions. The reporting date and onset date of the first diagnosed patient were taken as the arrival time, respectively, to establish a linear regression model of effective distance and arrival time. In different provinces and cities, the logarithm of the cumulative number of confirmed cases with a base of 5 was taken as the criteria to determine the level of the cumulative confirmed cases. Based on this, the linear regression model of effective distance and the level of cumulative confirmed cases in the provincial and municipal units was established. Results: The linear correlation between the reporting date of the first confirmed patient and the effective distance was not strong. The coefficients of determination (R 2) for cities with and without the cities of Hubei Province were 0.36 and 0.44, respectively. And the linear correlation between the onset date of the first confirmed patient and the effective distance was strong. And the coefficients of determination (R 2) for cities with and without the cities of Hubei Province were 0.67 and 0.83, respectively. And the linear correlation between the level of cumulative confirmed cases in the provincial and municipal units and the effective distance was strong, with an R 2 of 0.87 and 0.84, respectively. The regression coefficients of each linear model were statistically significant (P < 0.001). Conclusion: The effective distance has a good fit with the model of the onset date of the first confirmed patient and the level of cumulative confirmed cases, which can predict the trajectory, time, and transmission range of the epidemic. It can be taken as the reference for the early warning, prevention, and control of sudden acute infectious diseases from a macro perspective.

RESUMO

Objective: Peer attitude towards children with disabilities can significantly impact on the successful implementation of inclusive education. The current study examined the attitude of Chinese students toward peers with disabilities in relation to inclusive climate and empathy. Method: A total of 392 typically developing students (aging from 10 to 17 years old, with average age of 12.7) in primary and middle schools participated in the study by reporting the Inclusive Climate Scale, Peers Attitude to Students with Disabilities Scale, and Balanced Emotional Empathy Scale. Results: We found that students held a neutral attitude to peers with disabilities, and girls were more acceptable than boys. There were positive relationships among inclusive climate, empathy and attitude to classmates with disabilities. The mediation analysis showed that empathy played a partial mediation role between inclusive climate and the peers' attitude towards children with disabilities. Conclusion: Implications for improving students' attitude on peers with disabilities were discussed in the paper.

RESUMO

Background: Due to its convenience, wide availability, low usage cost, neural machine translation (NMT) has increasing applications in diverse clinical settings and web-based self-diagnosis of diseases. Given the developing nature of NMT tools, this can pose safety risks to multicultural communities with limited bilingual skills, low education, and low health literacy. Research is needed to scrutinise the reliability, credibility, usability of automatically translated patient health information. Objective: We aimed to develop high-performing Bayesian machine learning classifiers to assist clinical professionals and healthcare workers in assessing the quality and usability of NMT on depressive disorders. The tool did not require any prior knowledge from frontline health and medical professionals of the target language used by patients. Methods: We used Relevance Vector Machine (RVM) to increase generalisability and clinical interpretability of classifiers. It is a typical sparse Bayesian classifier less prone to overfitting with small training datasets. We optimised RVM by leveraging automatic recursive feature elimination and expert feature refinement from the perspective of health linguistics. We evaluated the diagnostic utility of the Bayesian classifier under different probability cut-offs in terms of sensitivity, specificity, positive and negative likelihood ratios against clinical thresholds for diagnostic tests. Finally, we illustrated interpretation of RVM tool in clinic using Bayes' nomogram. Results: After automatic and expert-based feature optimisation, the best-performing RVM classifier (RVM_DUFS12) gained the highest AUC (0.8872) among 52 competing models with distinct optimised, normalised features sets. It also had statistically higher sensitivity and specificity compared to other models. We evaluated the diagnostic utility of the best-performing model using Bayes' nomogram: it had a positive likelihood ratio (LR+) of 4.62 (95% C.I.: 2.53, 8.43), and the associated posterior probability (odds) was 83% (5.0) (95% C.I.: 73%, 90%), meaning that approximately 10 in 12 English texts with positive test are likely to contain information that would cause clinically significant conceptual errors if translated by Google; it had a negative likelihood ratio (LR-) of 0.18 (95% C.I.: 0.10,0.35) and associated posterior probability (odds) was 16% (0.2) (95% C.I: 10%, 27%), meaning that about 10 in 12 English texts with negative test can be safely translated using Google.

RESUMO

PURPOSE: To determine the effects of peak inspiratory pressure (PIP)-guided intracuff pressure (ICP) modulation of laryngeal mask airway (LMA) Supreme™ during laparoscopic cholecystectomy. METHODS: Totally 120 patients were randomly divided using computer-generated numbers into a control group (n = 60; ICP, 60 cmH2O) and a PIP group (n = 60), in which ICP was increased with 5 cmH2O each time from PIP level until no air leaks from the oropharynx. PIP, ICP, cuff volume (CV), oropharyngeal leak pressure (OLP) and leak fraction (LF) were recorded before and after pneumoperitoneum establishment. Postoperative pharyngolaryngeal complications (sore throat, dysphagia, pharyngeal hematoma, and dysphonia) were also recorded. RESULTS: Demographic data were similar in the two groups. The CV and ICP before and after pneumoperitoneum were significantly lower in the PIP group (CV: 15.6 ± 2.3 mL and 21.0 ± 2.6 mL; ICP: 14.3 ± 2.9 cmH2O and 20.5 ± 3.4 cmH2O) than in the control group (CV: 33.0 ± 2.8 mL and 32.8 ± 1.9 mL; ICP: 60.0 ± 0.1 cmH2O and 60.0 ± 0.1 cmH2O) (P < 0.05). Although OLP was lower in the PIP group (P < 0.05), the LF was similar in the two groups (P > 0.05). There were fewer postoperative pharyngolaryngeal complications in the PIP group (P < 0.05). CONCLUSIONS: Compared with a fixed ICP of 60 cmH2O, PIP-guided ICP modulation during LMA Supreme™ use provided effective airway sealing at a lower CV and ICP, and produced fewer postoperative pharyngolaryngeal complications in patients undergoing laparoscopic cholecystectomy.
