The impact of opioid administration on the incidence of postanaesthetic colic in horses.

Effective management of postoperative pain is essential to ensure patient welfare, reduce morbidity and optimize recovery. Opioids are effective in managing moderate to severe pain in horses but concerns over their adverse effects on gastrointestinal (GI) motility and associated increased colic risk limit their widespread use. Studies investigating the impact of systemic opioids on both GI motility and colic incidence in horses have yielded inconclusive outcomes. Therefore, this retrospective study aims to assess the influence of systemic administration of butorphanol, morphine, and methadone on post-anaesthetic colic (PAC) incidence. Horses undergoing general anaesthesia for non-gastrointestinal procedures that were hospitalized for at least 72 h post-anaesthesia were included in this study. Anaesthetised horses were stratified by procedure type into horses undergoing diagnostic imaging without surgical intervention, emergency or elective surgery. In addition, patients were grouped by opioid treatment regime into horses receiving no opioids, intraanaesthetic, short- (<24 h) or long-term (>24 h) postoperative opioids. Administered opioids encompassed butorphanol, morphine and methadone. The number of horses showing signs of colic in the 72 h after anaesthesia was assessed for each group. A total of 782 horses were included, comprising 659 undergoing surgical procedures and 123 undergoing diagnostic imaging. The overall PAC incidence was 15.1%. Notably, horses undergoing diagnostic imaging without surgery had a significantly lower PAC rate of 6.5% compared to those undergoing surgery (16.7%, p = 0.0146). Emergency surgeries had a significantly lower PAC rate of 5.8% compared to elective procedures (18%, p = 0.0113). Of the 782 horses, 740 received intraoperative opioids and 204 postoperative opioids, 102 of which long-term (≥24 h). Neither intraoperative (p = 0.4243) nor short-term postoperative opioids (p = 0.5744) increased PAC rates. Notably, only the long-term (≥24 h) administration of morphine significantly increased PAC incidence to 34% (p = 0.0038). In contrast, long-term butorphanol (5.3% PAC, p = 0.8482) and methadone (18.4% PAC, p = 0.6161) did not affect PAC rates. In summary, extended morphine administration was the only opioid treatment associated with a significantly increased risk of PAC.

Effect of a Nurse-Led Cognitive-Behavioral Therapy on Sleep Quality in Patients Undergoing Open Heart Surgery: A Prospective Randomized Clinical Trial

Background: Sleep disorders are one of the most common complications in patients undergoing open-heart surgery. Cognitive-behavioral therapy (CBT-I) is used as a way to improve sleep quality. Objectives: This study aimed to determine the effect of a nurse-led CBT-I on sleep quality among patients undergoing open-heart surgery. Methods: This prospective randomized clinical trial was conducted on 90 patients undergoing open-heart surgery in both intervention and control groups (N = 45). The control group received routine care. The intervention group received 10-12 sessions of nurse-led CBT-I. The demographic questionnaire and the Pittsburgh Sleep Quality Index (PSQI) were used to collect data. The data was analyzed in SPSS v. 22 software using X2, independent sample t -test, analysis of covariance (ANCOVA), and paired t-test. Results: The majority of samples were in the age range of 31 - 40 years (33.33%) and male (53.33%). The results of the independent t-test showed that the mean total PSQI score in the 2 groups before the intervention was not significantly different (P = 0.245). Also, the results of ANCOVA showed that the mean total PSQI score after the intervention has a significant difference in the 2 groups (P = 0.0001). Conclusions: Nurse-led CBT-I intervention helps to improve the sleep quality of patients after open-heart surgery by reducing their automatic thoughts that affect behavior. Thus, it is recommended that training in nurse-led CBT-I be included in the nurses' academic training program, as well as in continuing education programs for nurses working in heart surgery wards.

Management of Hepatocellular Carcinoma in 2024: The Multidisciplinary Paradigm in an Evolving Treatment Landscape.

Liver cancer is the third most common cause of cancer-related deaths worldwide, and hepatocellular carcinoma (HCC) makes up the majority of liver cancer cases. Despite the stabilization of incidence rates in recent years due to effective viral hepatitis treatments, as well as improved outcomes from early detection and treatment advances, the burden of HCC is anticipated to rise again due to increasing rates of metabolic dysfunction-associated steatotic liver disease and alcohol-related liver disease. The treatment landscape is evolving and requires a multidisciplinary approach, often involving multi-modal treatments that include surgical resection, transplantation, local regional therapies, and systemic treatments. The optimal approach to the care of the HCC patient requires a multidisciplinary team involving hepatology, medical oncology, diagnostic and interventional radiology, radiation oncology, and surgery. In order to determine which approach is best, an individualized treatment plan should consider the patient's liver function, functional status, comorbidities, cancer stage, and preferences. In this review, we provide an overview of the current treatment options and key trials that have revolutionized the management of HCC. We also discuss evolving treatment paradigms for the future.

TCN-Based Distal Force Feedback Strategy of a Vascular Interventional Surgery Robot

Design and Analysis of a Breast Biopsy Robot Based on TRIZ Theory

Background: In recent years, more and more medical robots have formally stepped into clinical applications and are gradually being accepted by patients. Magnetic resonance image (MRI)-guided breast intervention robot is the most advanced technology for breast cancer treatment. Still, the very limited working space within the MRI scanner restricts the development of breast intervention robots. Objective: In this paper, a compact breast biopsy robot in MRI environment is proposed based on TRIZ theory. Methods: The structure of the robot is optimized by using the curvilinear principle and the asymmetry principle of TRIZ theory to obtain a modified cartesian coordinates robot for breast biopsy. The coordinate systems of the robot are established using D-H method. Next, 3D visualization simulation of the robot is performed by SimMechanics of MATLAB, and then kinematic simulation and workspace simulation analysis are carried out. Results: The simulation results show that motion space of the end effector of the robot meets the requirements of breast intervention surgery, and the robot structure is simple and effective. Conclusion: In this paper, a compact breast biopsy robot in MRI environment is proposed. Through the Simulink module of MATLAB to analyze its workspace, it is obtained that its working range is 250mm × 300mm × 200mm, which can cover any position in breast tissue. At the same time, the simulation results of the workspace also show that the structure optimization of the breast biopsy robot based on TRIZ theory is reasonable.

Characteristics of non-carbapenemase producing carbapenem-resistant Klebsiella pneumoniae from a tertiary hospital in China.

The spread of carbapenem-resistant Klebsiella pneumoniae (CRKP) is a substantial severe global public health burden. Non-carbapenemase-producing CRKP (non-CP-CRKP) is increasingly recognized as the source of severe infections. We analyzed the genotypic, and phenotypic profiles of non-CP-CRKP strains with the whole-genome sequences isolated between 2017 and 2019 and the clinical characterization of non-CP-CRKP infection. A total of 91 CRKP strains were collected, of which 5 (5.49%) strains were non-CP-CRKP. Four strains were from male patients; three strains were isolated from the bile of patients who underwent biliary interventional surgery and four had a history of antibiotic exposure. Three strains were sequence type (ST)11, one was ST1, and one was ST5523. The non-CP-CRKP strains were insusceptible to ertapenem. Three strains were susceptible to amikacin. All the strains were susceptible to imipenem, meropenem, tigecycline, ceftazidime/avibatam and polymyxin B. The β-lactamases of non-CP-CRKP predominantly included blaCTX-M, blaSHV, and blaTEM subtypes. Two site mutations in ompK36 (p.A217S and p.N218H) and four in ompK37 (p.I70M, p.I128M, p.N230G, and m233_None234insQ) were detected accounting for carbapenem resistance. Plasmids IncFI and IncFII were found in most strains. Genes encoding aerobactin, yersiniabactin and allantoin utilization were not detected in several isolates, and all non-CP-CRKP strains did not carry rmpA gene. Non-CP-CRKP infected patients had a history of previous antibiotic exposure or invasive procedures. Non-CP-CRKP strains were insusceptible to ertapenem. The mechanism of resistance includes β-lactamases production and the site mutations in ompK36 and ompK37. Several virulence genes were not detected in non-CP-CRKP.

Endovascular rotational atherectomy for multivessel coronary calcification involving the main trunk of left coronary artery and the left anterior descending artery

The revascularization strategy for severe calcification is one of the most pressing problems of modern percutaneous coronary interventions, since it is observed more and more often and significantly complicates traditional endovascular treatment. Currently, the method of choice for severe coronary calcification is rotational atherectomy, which allows modification of atheromatous mass with an increase in the vessel lumen to allow satisfactory balloon angioplasty and stenting. This article presents a case of a patient at very high cardiovascular risk with a burdened coronary history and severe clinical symptoms of exertional angina while receiving the optimal multiagent therapy. The examination revealed a multivessel coronary calcification, but the patient was denied coronary artery bypass grafting due to high perioperative risks. SYNTAX (Synergy between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery score) score I – 25,5 points, SYNTAX score II — 40,4% and 70,1% for percutaneous coronary intervention and coronary bypass surgery, respectively, European System for Cardiac Operative Risk Evaluation (EuroSCORE II) — 4,95%. Attempts at traditional percutaneous intervention were unsuccessful and the patient underwent endovascular rotational atherectomy followed by stenting of affected coronary segments, against the background of which there was an improvement in exercise tolerance with a decrease in angina class.

Reverse shock index multiplied by the motor component of the Glasgow Coma Scale predicts mortality and need for intervention in pediatric trauma patients.

Timely identification of high-risk pediatric trauma patients and appropriate resource mobilization may lead to improved outcomes. We hypothesized that reverse shock index times the motor component of the Glasgow Coma Scale (GCS) (rSIM) would perform equivalently to reverse shock index times the total GCS (rSIG) in the prediction of mortality and the need for intervention following pediatric trauma. The 2017-2020 National Trauma Data Bank data sets were used. We included all patients 16 years or younger who had a documented prehospital and trauma bay systolic blood pressure, heart rate, and total GCS. We excluded all patients who arrived at the trauma center without vital signs and interfacility transport patients. Receiver operating characteristic curves were used to model the performance of each metric as a classifier with respect to our primary and secondary outcomes, and the area under the receiver operating characteristic curve (AUROC) was used for comparison. Our primary outcome was mortality before hospital discharge. Secondary outcomes included blood product administration or hemorrhage control intervention (surgery or angiography) <4 hours following hospital arrival and intensive care unit admission. After application of exclusion criteria, 77,996 patients were included in our analysis. Reverse shock index times GCS-motor and rSIG performed equivalently as predictors of mortality in the 1- to 2- ( p = 0.05) and 3- to 5-year-old categories ( p = 0.28), but rSIM was statistically outperformed by rSIG in the 6- to 12- (AUROC, 0.96 vs. 0.95; p = 0.04) and 13- to 16-year-old age categories (AUROC, 0.96 vs. 0.95; p < 0.01). Reverse shock index times GCS-motor and rSIG also performed similarly with respect to prediction of secondary outcomes. Reverse shock index times GCS-total and rSIM are both outstanding predictors of mortality following pediatric trauma. Statistically significant differences in favor of rSIG were noted in some age groups. Because of the simplicity of calculation, rSIM may be a useful tool for pediatric trauma triage.

A modified triplet combination of docetaxel, oxaliplatin, and fluorouracil for gastric cancer (GC) with peritoneal carcinomatosis (PC) and inoperable malignant bowel obstruction (MBO): A multi-center, non-randomized, three-cohort, phase II trial (Zhen Jing).

TPS426 Background: For GC, PC is ranked as the most common in relapse and the second common in metastasis. MBO is a frequent and preterminal complication of PC, which has been reported to have a poor overall survival (OS) of only 3 months without effective treatment. Medical therapy of gastroenteric drainage and symptomatic drugs is the cornerstone management for MBO, just alleviating symptoms. Interventional therapy and surgery are effective but indicated in limited patients (pts) with strict selection. Chemotherapy is the mainstay treatment for metastatic GC but its role in MBO is poorly defined. Only a few retrospective studies are available, showing conflicting results on obstruction clearance (OC) and OS. Methods: We are conducting the Zhen Jing trial in five Chinese centers to investigate the tolerability and efficacy of a dose-sense regimen of docetaxel, oxaliplatin and fluorouracil in MBO from GC. Cohort A is for pts in first-line setting. Cohort B is for second-line setting. Cohort C is for pts who have failed to two or more regimens. Eligible pts will receive the same experimental regimen every 28 days: docetaxel 25 mg/m2 on days 1, 8, 15; oxaliplatin 85 mg/m2 on days 1, 15; fluorouracil 1200 mg/m2 24-hour infusion on days 1, 8, 15. A Simon's two-stage optimal design is applied (table below). The primary endpoint is 60-day OC rate. Secondary endpoints are 30-day OC rate, time to OC, OC duration, safety, overall survival and quality of life. Till July 2023, a total of 34 pts has been enrolled (16 in cohort A, 9 in cohort B, 9 in cohort C). Inclusion Criteria: 18-75 years old; Eastern Cooperative Oncology Group performance status ≤ 3; adenocarcinoma of stomach or gastroesophageal junction; peritoneal carcinomatosis established by imaging data or pathological evidence; MBO below the Treitz ligament based on clinical grounds or radiological findings; inappropriate for operation judged independently by two surgeons; written informed consent. Exclusion Criteria: Treated by a combination regimen containing all the study drugs; allergy to any of the study drugs; HER-2 gene overexpression; high microsatellite instability or mismatch repair deficiency; strangulated obstruction; active gastrointestinal bleeding; uncontrolled active infection; unstable heart diseases; severe lung diseases; central nervous system diseases; concomitant cerebral or meningeal metastasis; surgery or stent are required. Clinical trial information: NCT04840264 . [Table: see text]

Clinical Management of Major Postoperative Bleeding After Bariatric Surgery.

Major postoperative bleeding (mPOB) is the most common complication after bariatric surgery. Its intesity varies from self-limiting to life-threatening situations. Comprehensive decision-making and treatment strategies are mandatory but not established yet. We retrospectively analyzied our prospectively collected database of our bariatric patients during 2012-2022. The primary study endpoint was major postoperative bleeding (mPOB) defined as hemoglobin drop > 2g/dl or clinically relevant bleeding requiring intervention (transfusion, endoscopy or surgery). Secondary endpoints were overall complications according to Clavien-Dindo-Classification and comprehensive-complication-index (CCI). We identified 1017 patients, of whom 667 underwent gastric bypass (GB) and 350 sleeve gastrectomy (SG). Major postoperative bleeding occured in 39 patients (total 3.8%; 5.1% after GB and 2.3% after SG). Patients with mPOB were more often diagnosed with type 2 diabetes (p = 0.039), chronic kidney failure (p = 0.013) or received antiplatelet drug treatment (p = 0.003). The interval from detection to intervention within 24h was 92.1% (35/39). Blood transfusions were necessary in 20/39 cases (total 51.3%; 45.2% after GB and 75% after SG; p = 0.046). Luminal bleeding only occured after GB (19/31; 61.3%), while all mPOB after SG were intraabdominal (p = 0.002). Reoperations were performed in 21/39 (total 53.8%; 48.4% after GB and 75% after SG; p = 0.067). CCI in patients with mPOB was 34.7 overall, with 31.2 after GB and 47.9 after SG (p = 0.005). The clinical appearance of mPOB depends on the type of surgery with severe bleedings after SG. We suggest a surgery first approach for mPOB after SG and an endoscopy first approach after GB.

Relationship between vascular calcification, osteoporosis and systemic inflammation

A lot of patients with coronary heart disease often suffer from vascular calcification. In many cases it is accompanied by harmful cardiovascular events. The modern ideas of the relationship between osteoporosis, vascular calcification and inflammation, the general mechanisms of development of vascular calcification and low bone mineral density are discussed. Despite a growing number of studies concerning the combined pathology of the cardiovascular and skeletal systems, a causal relationship between vascular calcification and a decrease in bone mass has not yet been established. Moreover, there is insufficient data on the effect of inflammation on ectopic calcification. Based on the analysis of available clinical and experimental studies, this review describes the main pathogenetic mechanisms of vascular calcification in coronary atherosclerosis. The influence of calcium and vitamin D medicines on the development of vascular calcification is discussed in this article. The author’s attention is focused on early and long-term consequences of percutaneous coronary intervention and coronary bypass surgery in patients with vascular calcification.

Noninvasive carotid ultrasound for predicting vulnerable plaques of the coronary artery based on optical coherence tomography images.

The risk factors for coronary and carotid plaque development are consistent. Coronary plaque rupture is a major cause of adverse cardiovascular events. Ultrasound can evaluate vulnerable carotid plaques and provide information for predicting vulnerable coronary plaques identified by optical coherence tomography (OCT). This study aimed to investigate the predictive role of non-invasive carotid ultrasound in OCT diagnosis of atherosclerotic vulnerable plaque. A total of 70 participants, including 35 patients with and 35 without vulnerable coronary plaque, were enrolled in this case-control study at Beijing Anzhen Hospital from 2016 to 2021. The data of 70 patients with suspected coronary heart disease who had undergone OCT examination during percutaneous coronary intervention (PCI) surgery and completed carotid ultrasound examination within 3 days before PCI were analyzed retrospectively. According to the OCT diagnostic criteria for vulnerable plaques, the patients were divided into the vulnerable-plaque group and the stable-plaque group. Univariate and binary logistic regression analyses assessed risk factors for vulnerable coronary plaque. Receiver operating characteristic (ROC) curve analysis was used to determine the predictive power of carotid plaque features. The univariate analysis demonstrated that the differences in high-sensitivity C-reactive protein levels and carotid plaque characteristics (irregular fibrous cap, heterogeneous plaque, hypoechoic plaque, plaque calcification, and a plaque thickness of greater than 3 mm) between the two groups were statistically significant. The logistic multivariate regression analysis revealed that an irregular fibrous cap of a carotid plaque [odds ratio (OR) =4.819; 95% confidence interval (CI): 1.106-22.867; P=0.048] and a hypoechoic plaque (OR =9.632; 95% CI: 2.138-43.384; P<0.05) were independent risk factors for predicting vulnerable plaques of the coronary artery. Noninvasive carotid ultrasound is feasible and clinically valuable for predicting vulnerable and asymptomatic coronary plaques defined by OCT. With this method, adverse events can be diagnosed and treated in advance.

The Systemic Immune-Inflammation Index Predicts In-Hospital Mortality in Patients Who Underwent On-Pump Cardiac Surgery.

Systemic immune-inflammation index (SII), a new inflammatory index calculated using platelet, neutrophil, and lymphocyte counts, has been demonstrated to be an independent risk factor for the identification of high-risk coronary artery disease in patients undergoing percutaneous coronary intervention and cardiovascular surgery with cardiopulmonary bypass (CPB). The relationship between SII and CPB-related mortality rates remains unclear. This research was designed to investigate the use of SII to predict in-hospital mortality in patients undergoing cardiac surgery with CPB. Four hundred eighty patients who underwent a cardiac procedure involving CPB over 3 years, were obtained from the hospital's database. The demographic data, comorbidities, hematological and biochemical profiles, and operative data of the groups were compared. Multiple logistic regression analyses were done to determine independent predictors of mortality. Prognostic factors were assessed by multivariate analysis, and the predictive values of SII, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) for mortality were compared. A p-value <0.05 was considered significant. Of 480 patients, 78 developed in-hospital mortality after cardiac surgery. SII was an independent predictor of in-hospital mortality (Odds ratio: 1.003, 95% confidence interval: 1.001-1.005, p<0.001). The cut-off value of the SII was >811.93 with 65% sensitivity and 65% specificity (area under the curve: 0.690). The predictive values of SII, PLR, and NLR were close to each other. High preoperative SII scores can be used for early determination of appropriate treatments, which may improve surgical outcomes of cardiac surgery in the future.

Correlation Between Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio with Risk Stratification Indicators and Thrombus Burden in Patients with Moderate-to-High Risk Acute Pulmonary Embolism, and Changes After Treatment.

To investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and risk stratification indicators as well as thrombus burden in patients with moderate-to-high risk acute pulmonary embolism (APE), and to assess the changes in these parameters following interventional therapy. This study retrospectively included patients with moderate-to-high risk APE who were admitted to the Department of Interventional Vascular Surgery at Putian First Hospital from May 2020 to May 2024. All patients received anticoagulation therapy, pulmonary artery catheter-directed thrombolysis, and/or mechanical thrombectomy. Patients were further divided into subgroup A if they did not present with any of the following conditions at admission: a) acute inflammatory diseases (including lung infections); b) malignant tumors; c) history of trauma or surgery within the past 2 months. Patients with any of the aforementioned conditions were classified as subgroup B. Additionally, 50 healthy individuals were randomly selected as the healthy control group. The NLR and PLR in subgroup A were significantly lower than those in subgroup B (P < .01). Compared with the healthy control group, the NLR in the APE group and subgroup A was significantly higher (P < .001). There were no significant differences in NLR and PLR between the troponin I-negative and troponin I-positive groups (P > .05), or between the N-terminal pro-B-type natriuretic peptide (NT-proBNP)-negative and NT-proBNP-positive groups (P > .05). There were no significant correlations between NLR and PLR with risk stratification indicators and pulmonary artery embolism index (P > .05). Compared with before treatment, NLR, troponin I, NT-proBNP, right ventricular diameter/left ventricular diameter ratio, and pulmonary artery embolism index were significantly reduced after treatment (P < .05), while there was no significant difference in PLR before and after treatment (P > .05). Elevated NLR in patients with APE, which decreases after effective treatment, may be used for assessing disease status and treatment efficacy. However, there is no correlation between NLR and risk stratification indicators or thrombus burden. PLR does not demonstrate significant value in assessing APE.

O Índice de Imuno Inflamação Sistêmica Prevê Mortalidade Hospitalar em Pacientes Submetidos à Cirurgia Cardíaca com Circulação Extracorpórea

Effect of nursing risk management on perioperative care in cardiovascular interventional catheterization rooms.

To investigate the effect of nursing risk management in cardiovascular interventional catheterization rooms, reduce perioperative complications and enhance treatment outcomes. This retrospective study included 60 patients who underwent cardiovascular interventional surgery at the Fourth Affiliated Hospital of Soochow University from January 2023 to January 2024. Patients were divided into two groups based on the nursing approach received. The observation group (n=32) received nursing risk management intervention, while the control group (n=28) received routine nursing care. Outcomes compared included psychological status, nursing satisfaction, postoperative complications, and general clinical information. Both groups showed significant reductions in Self-Rating Anxiety Scale and Self-Rating Depression Scale scores, with the observation group achieving lower scores post-intervention (both P<0.05). Nursing satisfaction was higher in the observation group (93.75%) compared to the control group (78.57%) (P<0.05). The rate of postoperative complications was lower in the observation group (6.2% vs. 17.9%) (P=0.047). Multiple regression analysis identified urinary retention (P=0.007) and nursing risk management (P<0.001) as independent factors influencing patients' psychological status. Nursing risk management in cardiovascular interventional catheterization rooms can reduce anxiety and depression, decrease postoperative complications, and improve nursing satisfaction.

Application of a Quality Control Circle Method in Reducing the Incidence Rate of Vasovagal Reflex in Patients Treated with Vascular Intervention Surgery

Objectives: In this paper, we discuss the effect of a quality control circle (QCC) method on reducing the incidence rate of vasovagal reflex (VVR) in patients treated with vascular intervention surgery. Methods:We selected 190 patients treated with vascular intervention surgery at Yantai Yuhuangding Hospital (Yantai City, Shandong Province) from January 22, 2021 to February 24, 2023. A random number table was used to divide these patients into a research group (N=95) and a control group (N=95. We compared multiple indices between the 2 groups. Results: The incidence rate of VVR in the research group was lower than in the control group (10.53% vs 22.11%, χ2 = 4.664, p &lt; .05). The comparison results of physical status between the 2 groups showed that the heart rate (83.00 ± 5.00 vs 67.00 ± 5.00), systolic blood pressure (123.36 ± 11.42 vs 112.36 ± 10.31), diastolic blood pressure (81.32 ± 9.76 vs 64.81 ± 8.94), urinary dysfunction (19 vs 41), abdominal discomfort (14 vs 34), defecation desire (11 vs 32), and health survey (65.37±9.52 vs 57±9.88) scores of the research group were greater than those of the control group (p &lt; .05). The depression and anxiety levels, degree of compliance with medical orders and level of satisfaction in the research group were greater than in the control group (p &lt; .05). Conclusions: The application of QCC will significantly reduce the incidence rate of VVR in patients treated with vascular intervention surgery, enhance communication and cooperation with patients, improve therapeutic efficiency, prevent surgical risks, and ensure safety.
