Abstract

We investigate the process $\eta_c \to {\bar{K}}^0K^+\pi^-$ by taking into account the $S$-wave ${K^*\bar{K}^*}$ and $\rho\omega$ interactions within the unitary coupled-channel approach, where the scalar meson $a_0(1710)$ is dynamically generated. In addition, the contributions from the intermediate resonances $K_0^*(1430)^{-}\to {\bar{K}}^0\pi^- $ and $K_0^*(1430)^{0}\to K^+\pi^-$ are also considered. We find a significant dip structure around 1.8~GeV, associated to the $a_0(1710)$, in the ${{\bar{K}}^0K^+}$ invariant mass distribution, and the clear peaks of the $K_0^*(1430)$ in the ${\bar{K}}^0\pi^-$ and $K^+\pi^-$ invariant mass distributions, consistent with the {\it BABAR} measurements. We further estimate the branching fractions $\mathcal{B}(\eta_c \to \bar{K}^{*0}K^{\ast+}\pi^-)= 5.5\times10^{-3}$ and $\mathcal{B}(\eta_c \to \omega\rho^+\pi^-)= 7.9\times10^{-3}$. Our predictions can be tested by the BESIII and BelleII experiments in the future., Comment: 9 pages, 9 figures

Abstract

Background The elderly are at high risk for acute pulmonary embolism (APE) , and the difficulty of early identification and diagnosis of APE in the elderly has made the active search for an optimal prediction method for elderly patients with suspected APE a medical problem that must be faced. Objective To investigate the predictive value of the 4-level Clinical Pretest Probability Score (4PEPS) for pulmonary embolism (PE) in elderly patients with suspected APE. Methods Basic information and related clinical data were collected from elderly (age≥60 years) hospitalized patients who completed spiral CT pulmonary arteriography (CTPA) examinations in the Third Affiliated Hospital of Zunyi Medical University from 2017 to 2021. The study subjects were divided into the APE group and non-APE group according to the CTPA criteria for the diagnosis of PE in 2018 Guidelines for the Diagnosis, Treatment and Prevention of Pulmonary Thromboembolism. The 4PEPS, Standard algorithm, age-adjusted D-dimer (AADD) algorithm, YEARS algorithm and pulmonary embolism graduated D-dimer (PEGeD) algorithm were used to predict the APE of the study subjects, respectively, who were divided into the positive and negative groups, and the number of true positives, true negatives, false positives and false negatives of each prediction method was counted. The efficacy evaluation indexes of the five prediction method were calculated and their prediction values were compared. Results Among 1 193 elderly hospitalized patients who completed CTPA examination, 608 (50.96%) were male and 585 (49.04%) were female, with a median age of 74 (68, 81) years; 323 (27.07%) were APE patients and 870 (72.93%) were non-APE patients; there was no statistically significant difference between elderly APE patients and elderly non-APE patients in terms of gender and age (P>0.05) . 4PEPS, AADD algorithm, Standard algorithm, YEARS algorithm and PEGeD algorithm for elderly patients with suspected APE had a sensitivity of 95.05%, 97.83%, 98.76%, 97.21%, 97.83%, the specificity of 31.84%, 18.16%, 12.87%, 22.41%, 22.41%, the correctness of 48.95%, 39.73%, 36.13%, 42.67%, 42.83%, Youden index of 0.27, 0.16, 0.12, 0.20, 0.20. The net reclassification improvement (NRI) of 4PEPS, Standard algorithm, YEARS algorithm and PEGeD algorithm compared to AADD algorithm were 0.218, -0.087, 0.073, and 0.085, the difference of the NRI of 4PEPS compared to AADD algorithm was statistically significant (P

Abstract

Objective To investigate the effect of endotracheal suctioning method using suctioning sputum with suctioning salivary tube in patients with craniocerebral injury undergoing tracheotomy. Methods A randomized controlled trial was conducted in 106 patients with traumatic brain injury after tracheotomy who met the inclusion criteria. According to the random number table method, they were divided into two groups, with 53 cases in each group. The experimental group was treated with endotracheal suctioning method using sputum suction tube combined with sputum suction tube, while the control group was treated with routine sputum suction method using sputum suction tube . The secretion severity grade under electronic laryngoscope swallowing function assessment (FEES) before and after sputum aspiration was compared between the two groups. The number of sputum aspiration, blood oxygen saturation and heart rate changes at 1 minute before and after sputum aspiration were observed in the two groups at 1, 3 and 7 days after admission. The mucosal damage under electronic hose bronchoscopy was observed in the two groups at 1, 3 and 7 days after admission. Results The severity of FEES was significantly lower in the experimental group than in the control group (P
