[PMID: 39151210 DOI: 10.1016/j.ijnurstu.2024.104867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 07/25/2024] [Accepted: 07/26/2024] [Indexed: 08/18/2024]
Abstract
BACKGROUND Venous thromboembolism is the leading cause of death in cancer patients, second only to tumor progression. The Khorana score is recommended by clinical guidelines for identifying ambulatory cancer patients at high risk of venous thromboembolism during chemotherapy. However, its predictive performance is debated among cancer patients. OBJECTIVES To map the applicability of the Khorana score in cancer patients and to assess its predictive performance across various cancer types, providing guidance for clinicians and nurses to use it more appropriately. DESIGN Systematic review and meta-analysis. METHODS A comprehensive literature search of the electronic database was first conducted on August 30, 2023, and updated on May 20, 2024. Studies examining the Khorana score's predictive performance (including but not limited to the areas under the curve, C-index, and calibration plot) in cancer patients were included. The Prediction Model Risk of Bias Assessment Tool (PROBAST) was applied to evaluate the methodological quality of the included studies. Data synthesis was achieved via random-effects meta-analysis using the R studio software. The subgroup analysis was performed according to the study design, clinical setting, cancer type, anti-cancer treatment stage, and country. RESULTS The review incorporated 67 studies, including 58 observational studies and nine randomized controlled trials. All included studies assessed the Khorana score's discrimination, with the C-index ranging from 0.40 to 0.84. The pooled C-index for randomized controlled trials was 0.61 (95 % CI 0.51-0.70), while observational studies showed a pooled C-index of 0.59 (95 % CI 0.57-0.60). Subgroup analyses revealed the pooled C-index for lung cancer, lymphoma, gastrointestinal cancer, and mixed cancer patients as 0.60 (95 % CI 0.53-0.67), 0.56 (95 % CI 0.51-0.61), 0.59 (95 % CI 0.39-0.76), and 0.60 (95 % CI 0.58-0.61), respectively. Inpatient and outpatient settings had the pooled C-index of 0.60 (95 % CI 0.58-0.63) and 0.58 (95 % CI 0.55-0.61), respectively. Calibration was assessed in only four studies. All included studies were identified to have a high risk of bias according to PROBAST. CONCLUSION The Khorana score has been widely validated in various types of cancer patients; however, it exhibited poor capability (pooled C-index<0.7) in accurately discriminating VTE risk among most types of cancer patients either in inpatient or outpatient settings. The Khorana score should be used with caution, and high-quality studies are needed to further validate its predictive performance. REGISTRATION The protocol for this study is registered with PROSPERO (registration number: CRD42023470320).

[PMID: 38598030 PMCID: PMC11006731 DOI: 10.1007/s11701-024-01931-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Accepted: 03/24/2024] [Indexed: 04/11/2024]
Abstract
Currently, there is no specific perioperative nursing standard for RARC based on the ERAS concept. This retrospective study investigates to analyze the effect of RARC-ERAS nursing program on VTE and other clinical outcomes in patients undergoing RARC surgery. This retrospective study included 216 patients undergoing RARC surgery From January 1, 2022 to December 30, 2023, and propensity score adjustment analysis was applied. The study compares a control group receiving traditional nursing and an observation group receiving RARC-ERAS nursing program. Perioperative variables and other postoperative complications were retrieved from the hospital medical records. After propensity score matching, there were no significant differences in the demographic and clinical characteristics between the two groups (p > 0.05). The ERAS group exhibited aa significantly higher rate of postoperative unobstructed venous blood flow in the lower extremities by color Doppler ultrasound as compared to the control group (94.6% VS 80.4%, p = 0.042). Before anesthesia induction, lower preoperative anxiety and surgical information needs scores were observed in the ERAS group than in the control group (p < 0.05). Compared to the control group, the ERAS group demonstrated a shorter surgical duration, a lower incidence of perioperative hypothermia, less time needed for getting out of bed, anal exhaust, and for defecation after returning to the ward (p < 0.05). RARC-ERAS nursing program significantly increased the rate of postoperative unobstructed venous blood flow in the lower extremities by color doppler ultrasound, lower preoperative anxiety and intraoperative hypothermia in patients undergoing RARC. This nursing approach presents a valuable strategy for enhancing patient outcomes and merits further exploration in clinical practice.Trial registration:ChiCTR2400081118; http://www.chictr.org.cn , Principal investigator: Mang-mang He, Date of registration: Feb 22, 2024.

Abstract
Objective: COVID-19 is a sort of infectious disease caused by a new strain of coronavirus. This study aims to develop a more accurate COVID-19 diagnosis system. Methods: First, the n-conv module (nCM) is introduced. Then we built a 12-layer convolutional neural network (12l-CNN) as the backbone network. Afterwards, PatchShuffle was introduced to integrate with 12l-CNN as a regularization term of the loss function. Our model was named PSCNN. Moreover, multiple-way data augmentation and Grad-CAM are employed to avoid overfitting and locating lung lesions. Results: The mean and standard variation values of the seven measures of our model were 95.28 ± 1.03 (sensitivity), 95.78 ± 0.87 (specificity), 95.76 ± 0.86 (precision), 95.53 ± 0.83 (accuracy), 95.52 ± 0.83 (F1 score), 91.7 ± 1.65 (MCC), and 95.52 ± 0.83 (FMI). Conclusion: Our PSCNN is better than 10 state-of-the-art models. Further, we validate the optimal hyperparameters in our model and demonstrate the effectiveness of PatchShuffle.

Sarcopenia as an independent predictor for venous thromboembolism events in bladder cancer patients undergoing radical cystectomy. Support Care Cancer 2021; 30:1191-1198. [PMID: 34453568 DOI: 10.1007/s00520-021-06423-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 07/07/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Sarcopenia has been proved to be related to the prognosis of patients with bladder cancer (BC) after radical cystectomy (RC). The relationship between sarcopenia and the occurrence of venous thromboembolism (VTE) after RC is unclear. METHODS We collected data of 252 BC patients treated with RC at our institution. Data was obtained from the electronic medical record database. Sarcopenia was defined by the third lumbar vertebra skeletal muscle index (SMI) which was measured using preoperative computed tomography. The primary outcome was the incidence of VTE within 30 days after the surgery in sarcopenia and non-sarcopenia groups. Outcomes between the two cohorts were compared using univariate analysis. Multivariate logistic regression was used to control for differences between cohorts. RESULTS Two hundred fifty-two patients were enrolled, of which 85 (33.7%) patients were in sarcopenia group, while 167 (66.3%) patients were not in sarcopenia group. The incidence of total VTE in sarcopenia group was higher than that in the extended group (10.6% vs. 1.8%, p = 0.005). Sarcopenia did not cause an increase in other postoperation 30 days complications (all p > 0.05). Multivariate analysis confirmed sarcopenia was independently associated with increased odds of VTE (OR = 4.18, 95% CI [1.01-17.27]; p = 0.048). Subgroup analysis showed that patients with VTE tended to be older (76.5 vs 66.0, p = 0.025) and have higher proportion of diabetes (58.3% vs 14.2%, p < 0.001) as well as lower level of serum albumin (35.0 g/L vs 40.4 g/L, p = 0.023) compared with those without VTE. CONCLUSIONS Sarcopenia was an independent predictor for VTE with patients undergoing RC for BC.
