As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022. Among the 135 staff members interviewed, only 41% had received training in blood transfusion. A majority (65.2%) of the staff noted that a mismatch in cross-matching led to transfusion complications. Two-thirds (66.7%) identified chills as the primary clinical sign of potential accidents. Regarding elements to monitor during a reaction, hemolysis (78.5%) and temperature (76.3%) were most commonly mentioned. Surprisingly, more than half (53.3%) of the personnel interviewed did not conduct post-transfusion monitoring. This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.展开更多

The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.展开更多

These risks have sparked an ongoing debate regarding the overall impact of transfusions on patient outcomes. Thus, this study aimed to evaluate the impact of Red Blood Cells (RBCs) and/or platelet transfusion on the infection incidence and overall survival in AHSCT patients. Methods: We performed a retrospective analysis of clinical and laboratory data of sixty adult patients with primary malignant hematological disorder who had undergone AHSCT. Participants’ data were categorized into two groups;Group 1 (low transfusion group) consisted of patients receiving 10 units. Quantitative data were expressed as mean ± SD. The t-test of significance and Chi-square (χ2) test were used, with p ≤ 0.05 considered significant. Result: A total of 60 patients’ data was included. In Group 1, out of 30 patients, 13 (43.33%) developed infections. In contrast, Group 2 had 21 (70%) out of 30 patients develop infections. Group 1 had a higher survival rate (57.8%) than Group 2 (transfusion > 10 units) (46.2%) with a chi-square value = 23.56, and p-value Conclusion: The volume of blood product transfusions has a considerable impact on patient outcomes, particularly infection and survival rates. Additional long-term prospective studies and larger randomized controlled trials are needed to strengthen the evidence for determining transfusion protocols for these patients.展开更多

The main objective was to study the role of blood transfusion in the management of obstetric emergencies. During the study period we recorded 434 cases of obstetric emergencies of which 116 cases required an emergency blood transfusion or 26.73%. The most frequently found indications for blood transfusion are hemorrhages of the immediate postpartum 46.6% followed by severe malaria on pregnancy 27.6%. Blood remains the most prescribed and available Labile blood product in the department. Maternal prognosis was improved in 92.2%.展开更多

The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip arthroplasty in order to guide a blood-saving program. Method: Retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion data, anesthetic and intraoperative data. The primary outcome was intraoperative or postoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 276 patients included, 179 benefited from Total Hip Prosthesis (THP) and 97 from Intermediate Hip Prosthesis (IHP). Spinal anesthesia was performed in 67.4% of patients. The ASA 2 score predominated (65.9%). The transfusion incidence was 56.9% (157/276). Tranexamic acid was used in 16.3% (45/276) of patients. The average bleeding was 528 ± 405 ml. Preoperative anemia (OR = 0.78, 95% CI [0.66 - 0.91]) and total hip prosthesis (OR = 2.02 95% CI [1.11 - 3.67]) were predictors of bleeding and transfusion to be significant. The average serum hemoglobin predictive of a transfusion was 11.6 ± 1.8. ASA score and operative time were not found as risk factors for bleeding and transfusion. Conclusion: The incidence of transfusion is high. Preoperative anemia remains a major but modifiable risk factor unlike the choice of implant. The implementation of a patient blood management protocol could reduce this transfusion incidence.展开更多

Materials and Methods: this was a prospective, descriptive, analytical study from 01 January 2018 to 31 October 2018 in the gynecology and obstetrics department of the reference health center of Kalaban-Coro (Mali). Results: During the study period we recorded 32 cases of transfusion of the immediate postpartum out of 109 cases of hemorrhage or 29.35%;for a total of 2425 deliveries or a frequency of 1.31%. The main indications for blood transfusion were: postpartum haemorrhage due to tearing of the soft parts in 21.9%;retroplacental hematoma in 18.6%;uterine rupture in 12.5%;and placenta previa covering hemorrhagic in 12.5%. More than half of the transfused were evacuees, or 62.5%. Unmet transfusion requirements were 59.4%. The blood products requested were: whole blood in 99% of cases and fresh frozen plasma in only 1% of cases. Conclusion: the need for labile blood products remains a reality in obstetrics. The permanent availability of labile blood products improves the prognosis of immediate postpartum haemorrhages.展开更多

HIT can cause devastating thrombosis, making it one of the most serious adverse drug reactions encountered in clinical practice. We successfully treated a case of severe HIT presenting with thrombosis and life-threatening bleeding complications with intravenous immunoglobulin(IVIG), platelet transfusion and oral anticoagulant Rivaroxaban. In this case, we considered that IVIG played the most important role by preventing further thrombosis, increasing the platelet count, and ensuring the efficacy of Rivaroxaban. We therefore suggest that IVIG might be the optimal treatment for patients with this urgent condition.展开更多

文摘BACKGROUND Cesarean hemorrhage is one of the serious complications,and short-term massive blood transfusion can easily cause postoperative infection and physical stress response.However,predictive nursing intervention has important clinical significance for it.AIM To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section(CS).METHODS A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021.According to the different nursing methods,patients divided into control group(n=50)and observation group(n=50).Among them,the control group implemented routine nursing,and the observation group implemented predictive nursing intervention based on the control group.Moreover,compared the differences in stress res-ponse,complications,and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS.RESULTS The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing,and the psychological stress response of the observation group was significantly lower than that of the control group(P<0.05).The heart rate and mean arterial pressure(MAP)of the observation group during delivery were lower than those of the control group,and the MAP at the end of delivery was lower than that of the control group(P<0.05).Moreover,different pain scores improved significantly in both groups,with the observation group considerably less than the control group(P<0.05).After nursing,complications such as skin rash,urinary retention,chills,diarrhea,and anaphylactic shock in the observation group were 18%,which significantly higher than in the control group(4%)(P<0.05).CONCLUSION Predictive nursing intervention can effectively relieve the pain,reduce the incidence of complications,improve mood and stress response,and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.
文摘Blood transfusion is a complex activity, involving many actors. As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022.

This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.
文摘Objective: To develop and internally validate a nomogram to predict recurrence-free survival (RFS) including the time to radical cystectomy (RC) and perioperative blood transfusion (PBT) as potential predictors.Methods: Patients who underwent open RC and ileal conduit between January 1996 to December 2016 were split into developing (n=948) and validating (n=237) cohorts. The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.
文摘BACKGROUND The advent of coronavirus disease 2019(COVID-19)unveiled the worst national blood crisis that the United States had witnessed in over a decade.With the pandemic influencing the different stages of the acquisition of blood products outside the hospital setting,we aimed to explore the possible barriers contributing to the shortage of blood products within the medical community.the COVID era and pre-COVID era.METHODS We conducted a retrospective cross-sectional study on hospitalized patients distinguishing the pattern of blood transfusion during the COVID and pre-COVID era in a community hospital.Data was tabulated to include the number of red blood cell(RBC)transfusions and if transfusions met restrictive blood transfusion criteria as per institutional guidelines.Chi-square was applied to test the statistical association between qualitative variables.Unpaired t test and Mann Whitney U test were applied respectively to test the mean difference of quantitative variables.RESULTS A total of 208 patients were included in the study,of which 108 were during COVID era and 100 were during pre-COVID era.The leading reason for admission in both the COVID era and pre-COVID era transfused patients was shortness of breath(53.7%and 36%P=0.001),followed by gastrointestinal bleeding(25.9%and 21%P=0.001).There was a higher percentage of RBC transfusions in the intensive care unit in the COVID-era group than in the pre-COVID era group(38.9%vs 22%,P=0.008).The restrictive transfusion criteria were met in 62%vs 79%in the COVID and pre-COVID eras,respectively(P=0.008).CONCLUSION The COVID-era group received RBC transfusions with less stringent adherence to restrictive blood transfusion practices in comparison to pre-COVID era group.
文摘Background: While blood product transfusion is essential for managing hematologic deficits in Allogenic Hematopoietic stem cell transplant (AHSCT) recipients, it has risks including infectious disease transmission, alloimmunization, and transfusion reactions. These risks have sparked an ongoing debate regarding the overall impact of transfusions on patient outcomes. Thus, this study aimed to evaluate the impact of Red Blood Cells (RBCs) and/or platelet transfusion on the infection incidence and overall survival in AHSCT patients. Methods: We performed a retrospective analysis of clinical and laboratory data of sixty adult patients with primary malignant hematological disorder who had undergone AHSCT. Participants’ data were categorized into two groups;Group 1 (low transfusion group) consisted of patients receiving 10 units. Quantitative data were expressed as mean ± SD. The t-test of significance and Chi-square (χ2) test were used, with p ≤ 0.05 considered significant. Result: A total of 60 patients’ data was included. In Group 1, out of 30 patients, 13 (43.33%) developed infections. In contrast, Group 2 had 21 (70%) out of 30 patients develop infections. Group 1 had a higher survival rate (57.8%) than Group 2 (transfusion > 10 units) (46.2%) with a chi-square value = 23.56, and p-value Conclusion: The volume of blood product transfusions has a considerable impact on patient outcomes, particularly infection and survival rates. Additional long-term prospective studies and larger randomized controlled trials are needed to strengthen the evidence for determining transfusion protocols for these patients.
文摘Objective:To study the effect of the direct anti-human globulin test on the clinical efficacy of blood transfusion patients.Methods:52 transfused patients were selected for this study,of which 26 cases with positive direct anti-human globulin tests were included in the positive group,and another 26 cases with negative direct anti-human globulin tests were included in the negative group.The apparent efficacy of the patients in the two groups after blood transfusion was compared.Results:After blood transfusion,the apparent efficacy of the negative group was significantly higher,P<0.05;in the positive group,the proportion of the predominantly multi-antibody group was the highest;after blood transfusion,the post-transfusion apparent efficacy of the simple IgG group was higher than that of the multi-antibody group,P<0.05;comparing the intensity of the different antibodies resulted in the 1+group,and the 3+to 4+groups were significantly lower after blood transfusion,P<0.05.Conclusion:The use of the direct antiglobulin test in transfused patients showed that patients with positive results would have better clinical efficacy.Direct anti-human globulin tests will have an impact on the clinical efficacy of blood transfusion in patients with positive results,so it is very important to carry out a direct anti-human globulin test on blood transfusion patients.
文摘BACKGROUND Acute myeloid leukemia(AML)is one of the most common types of leukemia in adults.However,AML is relatively rare in the population overall,accounting for only about 1 percent of all cancers.Treatment for AML can be very effective for some patients,yet it leaves others with serious and even life-threatening side effects.Chemotherapy is still the primary treatment for most AML,but over time,leukemia cells become resistant to chemotherapy drugs.In addition,stem cell transplantation,targeted therapy,and immunotherapy are currently available.At the same time,with the progression of the disease,the patient may have corresponding complications,such as coagulation dysfunction,anemia,granulocytopenia,and repeated infection,so transfusion supportive therapy will be involved in the overall treatment regime.To date,few articles have reported on blood transfusion treatment options for patients with ABO subtypes AML-M2.Blood transfusion therapy is an important supportive treatment for AML-M2,and accurate determination of patients'blood type is one of the most important steps in the treatment process.In this study,we explored blood typing and supportive treatment strategies for a patient with A2 subtype AML-M2 to provide the basis for treatment for all patients.CASE SUMMARY In order to determine the blood type of the patient,serological and molecular biological methods were used for reference tests,and the genetic background was studied to determine the patient's final blood type and select the appropriate blood products for infusion treatment.According to the results obtained by serological and molecular biological methods,the blood type of the patient was A2 subtype;the genotype was A02/001;the irregular antibody screening was negative,and anti-A1 was found in the plasma.According to the overall treatment plan,active anti-infection,elevated cells,component blood transfusion support,and other rescue and supportive treatments were given,and the patient successfully passed the stage of myelosuppression after chemotherapy.Re-examination of bone marrow smears showed that AL was in complete remission of bone marrow signs,and minimal residual leukemia lesions suggested no cells with obvious abnormal immunophenotype(residual leukemia cells<10-4).CONCLUSION The infusion of patients with A2 subtype AML-M2 with A irradiated platelets and O washing red blood cells can meet the needs of clinical treatment.

文摘BACKGROUND Platelet transfusion is of great significance in the treatment of thrombocytopenia caused by myelosuppression during intensive chemotherapy in patients with acute leukemia.In recent years,with platelet transfusion increasing,ineffective platelet transfusion has become increasingly prominent.Generally speaking,platelet antibodies can be produced after repeated transfusion,thus rendering subsequent platelet transfusion ineffective.We report a case of first platelet transfusion refractoriness(PTR)in a patient with acute myelocytic leukemia(AML).Due to the rarity of such cases in clinical practice,there have been no relevant case reports so far.CASE SUMMARY A 51-year-old female patient attended the hospital due to throat pain and abnormal blood cells for 4 d.Her diagnosis was acute myelocytic leukemia[M2 type Fms related receptor tyrosine kinase 3,Isocitrate Dehydrogenase 1,Nucleophosmin 1,Neuroblastoma RAS viral oncogene homolog(+)high-risk group].She was treated with"IA"(IDA 10 mg day 1-3 and Ara-C 0.2 g day 1-5)chemotherapy.When her condition improved,the patient was discharged from the hospital,instructed to take medicine as prescribed by the doctor after discharge,and returned to the hospital for further chemotherapy on time.CONCLUSION We report a rare case of first platelet transfusion failure in a patient with AML during induction chemotherapy,which may be related to the production of platelet antibodies induced by antibiotics and excessive tumor load.This also suggests that we should consider the influence of antibiotics when the rare situation of first platelet transfusion failure occurs in patients with AML.When platelet antibodies are produced,immunoglobulins can be used to block antibodies,thereby reducing platelet destruction.For patients with PTR,both immune and non-immune factors need to be considered and combined in clinical practice along with individualized treatment to effectively solve the problem.
文摘This is a prospective and descriptive study carried out at the gynecology and obstetrics department of the reference health center of Fana from 01 May 2019 to 30 November or 7 months. The main objective was to study the role of blood transfusion in the management of obstetric emergencies. During the study period we recorded 434 cases of obstetric emergencies of which 116 cases required an emergency blood transfusion or 26.73%. The most frequently found indications for blood transfusion are hemorrhages of the immediate postpartum 46.6% followed by severe malaria on pregnancy 27.6%. Blood remains the most prescribed and available Labile blood product in the department. Maternal prognosis was improved in 92.2%.
文摘Background: Hip arthroplasty is a surgery with a high risk of bleeding. The main objective of this study was to research risk factors for bleeding and transfusion in patients undergoing hip arthroplasty in order to guide a blood-saving program. Method: Retrospective, monocentric, descriptive and analytical study carried out from June 2011 to June 2021 at the Omar Bongo Ondimba army training hospital. The variables studied were demographic characteristics, biological variables, transfusion data, anesthetic and intraoperative data. The primary outcome was intraoperative or postoperative transfusion. A univariate and multivariate analysis was conducted to identify the factors associated with the occurrence of a transfusion. Results: Of the 276 patients included, 179 benefited from Total Hip Prosthesis (THP) and 97 from Intermediate Hip Prosthesis (IHP). Spinal anesthesia was performed in 67.4% of patients. The ASA 2 score predominated (65.9%). The transfusion incidence was 56.9% (157/276). Tranexamic acid was used in 16.3% (45/276) of patients. The average bleeding was 528 ± 405 ml. Preoperative anemia (OR = 0.78, 95% CI [0.66 - 0.91]) and total hip prosthesis (OR = 2.02 95% CI [1.11 - 3.67]) were predictors of bleeding and transfusion to be significant. The average serum hemoglobin predictive of a transfusion was 11.6 ± 1.8. ASA score and operative time were not found as risk factors for bleeding and transfusion. Conclusion: The incidence of transfusion is high. Preoperative anemia remains a major but modifiable risk factor unlike the choice of implant. The implementation of a patient blood management protocol could reduce this transfusion incidence.

文摘Adequate oxygen in red blood cells carrying through the body to the heart and brain is important to maintain life.For those patients requiring blood,blood transfusion is a common procedure in which donated blood or blood components are given through an intravenous line.However,detecting the need for blood transfusion is time-consuming and sometimes not easily diagnosed,such as internal bleeding.This study considered physiological signals such as electrocardiogram(ECG),photoplethysmogram(PPG),blood pressure,oxygen saturation(SpO2),and respiration,and proposed the machine learning model to detect the need for blood transfusion accurately.For the model,this study extracted 14 features from the physiological signals and used an ensemble approach combining extreme gradient boosting and random forest.The model was evaluated by a stratified five-fold crossvalidation:the detection accuracy and area under the receiver operating characteristics were 92.7%and 0.977,respectively.
文摘The aim was to assess transfusion needs in the management of immediate postpartum haemorrhage. Materials and Methods: this was a prospective, descriptive, analytical study from 01 January 2018 to 31 October 2018 in the gynecology and obstetrics department of the reference health center of Kalaban-Coro (Mali). Results: During the study period we recorded 32 cases of transfusion of the immediate postpartum out of 109 cases of hemorrhage or 29.35%;for a total of 2425 deliveries or a frequency of 1.31%. The main indications for blood transfusion were: postpartum haemorrhage due to tearing of the soft parts in 21.9%;retroplacental hematoma in 18.6%;uterine rupture in 12.5%;and placenta previa covering hemorrhagic in 12.5%. More than half of the transfused were evacuees, or 62.5%. Unmet transfusion requirements were 59.4%. The blood products requested were: whole blood in 99% of cases and fresh frozen plasma in only 1% of cases. Conclusion: the need for labile blood products remains a reality in obstetrics. The permanent availability of labile blood products improves the prognosis of immediate postpartum haemorrhages.
文摘BACKGROUND Blood transfusion is common during the peri-transplantation period.The incidence of immunological reactions to blood transfusion after kidney transplantation and their consequences on graft outcomes have not been extensively studied.AIM To examine the risk of graft rejection and loss in patients who received blood transfusion in the immediate peri-transplantation period.METHODS We conducted a single-center retrospective cohort study of 105 kidney recipients,among them 54 patients received leukodepleted blood transfusion at our center between January 2017 and March 2020.RESULTS This study included 105 kidney recipients,of which 80%kidneys were from living-related donors,14%from living-unrelated donors,and 6%from deceased donors.Living-related donors were mostly first-degree relatives(74.5%),while the rest were second-degree relatives.The patients were divided into transfusion(n=54)and non-transfusion(n=51)groups.The average hemoglobin level at which blood transfusion was commenced was 7.4±0.9 mg/dL.There were no differences between the groups in terms of rejection rates,graft loss,or death.During the study period,there was no significant difference in creatinine level progression between the two groups.Delayed graft function was higher in the transfusion group;however,this finding was not statistically significant.A high number of transfused packed red blood cells was significantly associated with increased creatinine levels at the end of the study.CONCLUSION Leukodepleted blood transfusion was not associated with a higher risk of rejection,graft loss,or death in kidney transplant recipients.
文摘BACKGROUND The effect of perioperative blood transfusion(PBT)on the prognosis of ampullary carcinoma(AC)is still debated.AIM To explore the impact of PBT on short-term safety and long-term survival in AC patients who underwent pancreaticoduodenectomy.METHODS A total of 257 patients with AC who underwent pancreaticoduodenectomy between 1998 and 2020 in the Cancer Hospital,Chinese Academy of Medical Sciences,were retrospectively analyzed.We used Cox proportional hazard regression to identify prognostic factors of overall survival(OS)and recurrencefree survival(RFS)and the Kaplan-Meier method to analyze survival information.RESULTS A total of 144(56%)of 257 patients received PBT.The PBT group and nonperioperative blood transfusion group showed no significant differences in demographics.Patients who received transfusion had a comparable incidence of postoperative complications with patients who did not.Univariable and multivariable Cox proportional hazard regression analyses indicated that transfusion was not an independent predictor of OS or RFS.We performed Kaplan-Meier analysis according to subgroups of T stage,and subgroup analysis indicated that PBT might be associated with worse OS(P<0.05)but not RFS in AC of stage T1.CONCLUSION We found that PBT might be associated with decreased OS in early AC,but more validation is needed.The reasonable use of transfusion might be helpful to improve OS.
文摘BACKGROUND Gastric cancer(GC)is still a prevalent neoplasm around the world and its main treatment modality is surgical resection.The need for perioperative blood transfusions is frequent,and there is a long-lasting debate regarding its impact on survival.AIM To evaluate the factors related to the risk of receiving red blood cell(RBC)transfusion and its influence on surgical and survival outcomes of patients with GC.METHODS Patients who underwent curative resection for primary gastric adenocarcinoma at our Institute between 2009 and 2021 were retrospectively evaluated.Clinicopathological and surgical characteristics data were collected.The patients were divided into transfusion and non-transfusion groups for analysis.RESULTS A total of 718 patients were included,and 189(26.3%)patients received perioperative RBC transfusion(23 intraoperatively,133 postoperatively,and 33 in both periods).Patients in the RBC transfusions group were older(P<0.001),and had morecomorbidities(P=0.014),American Society of Anesthesiologists classification III/IV(P<0.001),and lower preoperative hemoglobin(P<0.001)and albumin levels(P<0.001).Larger tumors(P<0.001)and advanced tumor node metastasis stage(P<0.001)were also associated with the RBCtransfusion group.The rates of postoperative complications(POC)and 30-d and 90-d mortalitywere significantly higher in the RBC transfusion group than in the non-transfusion group.Lowerhemoglobin and albumin levels,total gastrectomy,open surgery,and the occurrence of POC werefactors associated with the RBC transfusion.Survival analysis demonstrated that the RBCtransfusions group had worse disease-free survival(DFS)and overall survival(OS)compared withpatients who did not receive transfusion(P<0.001 for both).In multivariate analysis,RBCtransfusion,major POC,pT3/T4 category,pN+,D1 lymphadenectomy,and total gastrectomywere independent risk factors related to worse DFS and OS.CONCLUSIONPerioperative RBC transfusion is associated with worse clinical conditions and more advancedtumors.Further,it is an independent factor related to worse survival in the curative intentgastrectomy setting.
文摘The pathophysiology of twin-to-twin transfusion syndrome(TTTS)is complex,and its understanding has evolved along with the evolution and revolution of fetal diagnostic and therapeutic techniques.Over the last few decades,several therapeutic interventions have been researched for improving the outcomes in TTTS.We present a summary of the current protocols for surveillance,diagnosis,and staging of TTTS in monochorionic pregnancies.We also describe in detail the technique for treatment of TTTS by endoscopic laser photocoagulation.
文摘Objective:To review the literature on long-term neurodevelopmental outcome after fetoscopic laser surgery for twin-twin transfusion syndrome(TTTS).Methods:A literature search in PubMed,Embase,Emcare,Web of Science,Cochrane library,and Academic Search Premier was performed.Inclusion criteria were studies between 2009 and 2019 in TTTS-survivors treated with fetoscopic laser surgery and followed-up after the neonatal period with cognitive developmental tests and neurologic exams.Exclusion criteria were non-English articles and reviews,case reports,letters,and guidelines.Results:Nineteen articles were included.Long-term severe neurodevelopmental impairment(NDI)was reported by seven and ranged from 4.0%to 18.0%with a mean of 9.7%(95%confidence interval(CI):7.8-11.5).The prevalence of cerebral palsy ranged from 1.6%to 18.2%,with a mean of 5.1%(95%CI:4.1-6.2).The mean prevalence of minor impairment was 13.7%(95%CI:11.4-16.0).However,only 78.9%(15/19)studies used a validated neurodevelopmental test.As studies lack uniform definitions of primary outcome,timing of follow-up,inclusion criteria,and methods,adequate comparison is hampered.Conclusion:The prevalence of severe NDI and cerebral palsy after fetoscopic laser surgery for TTTS in the last decade remains stable around 9.7%and 5.1%,respectively.International agreements on primary outcomes,methods,and follow-up are necessary to improve the knowledge of NDI in TTTS-survivors.
文摘Heparin-induced thrombocytopenia(HIT) is a relatively infrequent complication of heparin administration. HIT can cause devastating thrombosis, making it one of the most serious adverse drug reactions encountered in clinical practice. We successfully treated a case of severe HIT presenting with thrombosis and life-threatening bleeding complications with intravenous immunoglobulin(IVIG), platelet transfusion and oral anticoagulant Rivaroxaban. In this case, we considered that IVIG played the most important role by preventing further thrombosis, increasing the platelet count, and ensuring the efficacy of Rivaroxaban. We therefore suggest that IVIG might be the optimal treatment for patients with this urgent condition.
