ObjectiveTo investigate the incidence of perioperative anemia and the influencing factors of preoperative anemia in patients with colorectal cancer.MethodsThe clinicopathological data of 1 250 patients with colorectal cancer who underwent surgery in our hospital from January 1, 2019 to December 31, 2019 were analyzed retrospectively. According to the preoperative hemoglobin level, patients were divided into anemia group and non-anemia group. Univariate analysis and multivariate logistic regression analysis were used to explore the influencing factors of preoperative anemia in patients with colorectal cancer, and the effects of preoperative anemia on intraoperative blood transfusion, postoperative complications, and postoperative hospital stay were analyzed.ResultsThe incidence of preoperative anemia in patients with colorectal cancer was 40.6% (508/1 250), and the incidence of preoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 66.0% (192/291), 41.1% (139/338), and 28.5% (177/621), respectively. The incidence of postoperative anemia in patients with colorectal cancer was 69.4% (867/1 250), and the incidence of postoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 81.8% (238/291), 68.9% (233/338), and 63.8% (396/621), respectively. Multivariate logistic regression analysis showed that age >60 years old, nutritional risk screening 2002 ≥3, right colon cancer, T3–4 stage, and M1 stage were risk factors for preoperative anemia in patients with colorectal cancer (P<0.05). The rate of intraoperative blood transfusion and the incidence of postoperative complications in the preoperative anemia group of patients with colorectal cancer were higher than those in the non-anemia group (P<0.05). The postoperative hospital stay in the preoperative anemia group of patients with colon cancer was longer than that in the non-anemia group (P<0.05).ConclusionsThe incidence of perioperative anemia in patients with colorectal cancer is high. Advanced age, high nutritional risk, right colon cancer, T3–4 stage, and distant metastasis were the risk factors of preoperative anemia in patients with colorectal cancer. Preoperative anemia can increase the demand for intraoperative blood transfusion and the incidence of postoperative complications in patients with colorectal cancer, and prolong postoperative hospital stay of colon cancer patients.
ObjectiveTo investigate the status of roxadustat in patients undergoing maintenance peritoneal dialysis and analyze the factors affecting drug compliance. MethodsPatients with renal anemia undergoing maintenance peritoneal dialysis in West China Hospital of Sichuan University from July 2020 to March 2021 were selected. All patients took roxadustat orally. According to the medication compliance, the patients were divided into good compliance group and poor compliance group. The general information questionnaire and Morisky Medication Adherence Scale-8 (MMAS-8) were used to investigate and analyze the included patients, and their clinical examination indexes were collected. ResultsA total of 100 patients were included, Including 39 cases (39%) in the good compliance group and 61 cases (61%) in the poor compliance group. The average score of medication compliance of roxadustat was 5.19±1.72. Logistic regression analysis showed that drug cognition [odds ratio (OR)=0.099, 95% confidence interval (CI) (0.027, 0.365), P=0.001], medication troubles/complex protocol [OR=5.330, 95%CI (1.567, 18.132), P=0.007], and adverse drug reactions [OR=5.453, 95%CI (1.619, 18.368), P=0.006] were factors affecting patient compliance. Hemoglobin in the good compliance group was lower than that in the poor compliance group (Z=−2.259, P=0.024); there was no significant difference in other clinical examination indexes (P>0.05). ConclusionsThe overall compliance of oral roxadustat in maintenance peritoneal dialysis patients is poor, and the corresponding follow-up management system should be improved. Nurses should provide comprehensive and systematic medication guidance to patients, encourage them to fully understand the clinical manifestations, treatment schemes and prognosis of renal anemia, clarify the time, dose, possible adverse reactions and mitigation methods of roxadustat, etc., and help them to treat the disease with correct cognition and attitude, so as to improve their drug compliance.
ObjectiveTo explore the clinical manifestations, pathogenesis, prognosis and the therapeutic modalities of the patients with solid tumors combined with remarkable hematologic abnormalities. MethodsGastric cancer in a paitnet was diagnosed by endoscopy as well as pathological biopsy and myeloproliferative neoplasms (MPNs) were excluded through bone marrow examinations. Therefore, the primary and metastatic malignancies were excised. ResultsAlthough surgical operation improved the hematologic changes, the high tumor load caused the poor prognosis. ConclusionThe solid tumors may present with hematologic manifestations which is similar to the symptoms of MPNs; it belongs to the para-neoplastic phenomenon and may be an independent poor prognostic factors.
ObjectiveTo observe the effect of mild anemia on prognosis of hyperplastic diabetic retinopathy (PDR) treated by pars plana vitrectomy (PPV). MethodsA retrospective case-control study. From January 2021 to December 2022, 147 PDR patients with 147 eyes who received PPV treatment at Shenyang He Eye Hospital were included in the study. There were 147 eyes in 147 cases, 82 eyes in 82 males and 65 eyes in 65 females. Age was 25-79 (53.54±12.74) years old. A hemoglobin (Hb) of 90 to 120 g/L in men and 90 to 110 g/L in women was defined as mild anemia. According to Hb results, the patients were divided into mild anemia group and non-anemia group, with 39 cases (39 eyes) and 108 cases (108 eyes), respectively. The best corrected visual acuity (BCVA) test was performed using the international standard logarithmic visual acuity scale before and after the surgery, which was statistically converted to minimum resolved logarithmic (logMAR) visual acuity. The logMAR BCVA of the affected eye was 0.2-2.5 (1.60±0.62) before surgery. According to whether the BCVA improved by more than 3 lines 6 months after surgery, the affected eyes were divided into BCVA improved by more than 3 lines and BCVA improved by less than 3 lines, 117 eyes and 30 eyes, respectively. The patient's body mass index (BMI), BCVA at 6 months after surgery, and the occurrence of neovascular glaucoma (NVG) and recurrence of vitreous hemorrhage (RVH) were recorded. Independent sample t test was used for comparison between groups. Multivariate logistic regression analysis was performed to analyze the influencing factors of increased BCVA ≥3 rows after surgery. ResultsSix months after surgery, the logMAR BCVA of patients in mild anemia group and non-anemia group were 0.97±0.87 and 0.68±0.63, respectively. BCVA increased ≥3 in 26 (66.7%, 26/39) and 91 (84.3%, 91/108) eyes, respectively. logMAR BCVA (t=2.234) and BCVA increased by ≥3 rows of eyes (χ2=5.460) between the two groups, the differences were statistically significant (P=0.027, 0.019). Logistic regression analysis showed that baseline logMAR BCVA [odds ratio (OR) =4.291, 95% confidence interval (CI) 1.918-9.600, P＜0.001)], BMI (OR=1.248, 95%CI 1.057-1.472, P=0.009), the number of retinal laser photocoagulation during surgery (OR=1.001, 95%CI 1.000-1.002, P=0.038), mild anemia (OR=0.360, 95%CI 0.131-0.993, P=0.048), postoperative NVG (OR=0.156, 95%CI 0.033-0.726, P=0.018) and RVH (OR=0.264, 95%CI 0.086-0.808, P=0.020) were independent factors for BCVA improvement ≥3 lines after PPV. ConclusionsMild anemia has a certain effect on BCVA improvement after PPV of PDR. Mild anemia, post-operative NVG and RVH were independent risk factors for increasing BCVA ≥3 lines after PPV in PDR patients.
Objective To investigate the iron deficiency (ID) in children with congenital heart disease (CHD) and find high risk factors of ID. Methods The clinical data of 227 pediatric patients with CHD from February to June 2016 were retrospectively analyzed. The incidence of ID according to the result of iron metabolism examination (serum ferritin <12 μg/L as the diagnostic criteria) was investigated. According to their basic CHD types, patients were divided into a cyanotic group and an acyanotic group. We tried to find the high risk factors of ID in those pediatric CHD patients by comparing their age, gender, growth condition and blood routine test results. Results There were 19.8% pediatric CHD patients complicated by ID. The incidence of ID in the cyanotic patients was higher than that in the acyanotic patients (31.0% vs. 17.3%, P=0.045). In both groups, ID patients presented the characteristics of younger age, higher anemia rate, lower mean corpuscular volume (MCV), lower mean corpuscular hemoglobin (MCH), lower mean corpuscular-hemoglobin concentration (MCHC) and longer red blood cell distribution width (RDW). Conclusion Cyanosis, younger age (infant), anemia, decreased MCV, decreased MCH, decreased MCHC and increased RDW are high risk factors of ID in CHD children.
【Abstract】 Objective To report 1 case of acute hemolytic anemia after liver transplantation because of ABO compatibility and therapeutic experience. Methods The patient with liver cancer underwent orthotopic piggyback liver transplantation on September 2010 after radiofrequency ablation of the tumors. The donor and recipient ABO blood types were type O and type A, separately. Acute hemolytic anemia occurred at 10 days after transplantation and hemoglobin decreased to 56 g/L. The bone marrow showed active hyperplasia; and myeboid∶erythroid was 0.52∶1. The immunosuppressants were used and type O washed red blood cells were transfused immediately. Results The general condition of the patient was improved; hemoglobin increased gradually and returned to 111 g/L at 34 days after liver transplantation. At 12 months of follow-up, hemoglobin was within normal range. Conclusion Using graft blood type washed red blood cells transfusion and immunosuppressants could be an effective therapeutic procedure in the patient with ABO compatility graft when acute hemolytic anemia occurrs.
COPD 是一种可预防、可治疗, 以气流不完全可逆受限并呈进行性发展为特征的疾病, 与肺部对有害气体或有毒颗粒的异常炎症反应有关。在全球范围内COPD 是引起死亡和功能致残的主要疾病之一。COPD 在全球患病率和死亡率位居第四, 并呈不断上升的趋势[1] 。本病具有明显的肺外效应, 包括引起全身系统性炎症、代谢改变、神经激素激活,以及对肌肉骨骼、心血管系统等其他系统的影响等[2] 。既往认为COPD 仅引起红细胞增多, 但近期研究发现COPD 引起的系统性炎症可影响红细胞的生成, 贫血亦同样存在于部分COPD 患者。目前认为, COPD导致的贫血与其他许多慢性疾病如慢性心衰一样, 同属于一种慢性病性贫血( anemia of chronic disease, ACD) , 称为COPD 相关性贫血, 其患病率高于继发性红细胞增多症在COPD 的患病率[3-5] 。本文就COPD 相关性贫血的流行病学概况、病理生理机制、临床重要性及干预的最新研究进展如下综述。
