Methods: A total of 106 patients who underwent cardiovascular and cerebrovascular interventional treatment were collected and randomly divided into Group A (control) and Group B (observation), with 53 cases each. Group A received the routine nursing intervention and Group B received the interventional nursing intervention. The clinical efficacy, complications, negative emotions, quality of life, and nursing satisfaction of the two groups of patients were evaluated. Results: The total clinical effective rate of Group B (52/98.12%) was higher than that of Group A (45/84.91%) (χ^(2)= 4.371, P < 0.05). The total incidence of complications in Group B (2/3.78%) was lower than that of Group A (9/16.98%) (χ^(2)= 4.970, P < 0.05). The self-rating anxiety (SAS) score and self-rating depression (SDS) of Group B were lower than those of Group A (P < 0.001). The quality of life of Group B was significantly higher than that of Group A (P < 0.001). The nursing satisfaction of group B (51/96.22%) was higher than that of group A (43/81.13%) (χ^(2)= 6.014, P < 0.05). Conclusion: In the care of patients undergoing cardiovascular and cerebrovascular interventional therapy, interventional nursing intervention effectively improved the patient’s clinical efficacy, reduced the incidence of complications, reduced negative emotions, improved the quality of life, and increased nursing satisfaction.展开更多

Several deep learning techniques can be used to identify each of these anomalies in the chest x-ray images. Convolutional neural networks (CNNs) have shown great success in the fields of image recognition and image classification since there are numerous large-scale annotated image datasets available. The classification of medical images, particularly radiographic images, remains one of the biggest hurdles in medical diagnosis because of the restricted availability of annotated medical images. However, such difficulty can be solved by utilizing several deep learning strategies, including data augmentation and transfer learning. The aim was to build a model that would detect abnormalities in chest x-ray images with the highest probability. To do that, different models were built with different features. While making a CNN model, one of the main tasks is to tune the model by changing the hyperparameters and layers so that the model gives out good training and testing results. In our case, three different models were built, and finally, the last one gave out the best-predicted results. From that last model, we got 98% training accuracy, 84% validation, and 81% testing accuracy. The reason behind the final model giving out the best evaluation scores is that it was a well-fitted model. There was no overfitting or underfitting issues. Our aim with this project was to make a tool using the CNN model in R language, which will help detect abnormalities in radiography images. The tool will be able to detect diseases such as Pneumonia, Covid-19, Effusions, Infiltration, Pneumothorax, and others. Because of its high accuracy, this research chose to use supervised multi-class classification techniques as well as Convolutional Neural Networks (CNNs) to classify different chest x-ray images. CNNs are extremely efficient and successful at reducing the number of parameters while maintaining the quality of the primary model. CNNs are also trained to recognize the edges of various objects in any batch of images. CNNs automatically discover the relevant aspects in labeled data and learn the distinguishing features for each class by themselves.展开更多

Approximately 80% of these NCD-related deaths occur in LMICs. A quasi-experimental study utilizing a non-equivalent pre-and post-test was conducted from May 2022 to March 2023 with 370 study participants. Multistage cluster and random sampling were used to select ten community units, and therefore, 150 CHVs were chosen for the control unit, and 150 were used to form the interventional group. Data was collected from the KOBO app. Six (6) homogenous FGDs comprised ten members, and 10 KII were conducted across study sites. Quantitative data was analyzed using SPSS version 28.0, and qualitative data was audio-recorded, transcribed, and analyzed via N-Vivo 12. The study shows that 59.3% of respondents have minimal information, and 92.7% (n = 139) have no clear understanding of NCDs, with a pre-intervention capacity of 48.8%. Independent sample t-test showed a significant difference in capacity from a pre-intervention average of 48.75 (SD ± 5.7)%, which increased to 68.28 (SD ± 7.6)%, p < 0.001. A well-designed community interventional model plays a pivotal role in grassroots healthcare delivery but requires optimization for NCD management.展开更多

Providers respect patients’ values and preferences, address their emotional and social needs, and involve them and their families in decision making. According to the best of our knowledge, there is no evidence to prove, radiologists and radiographers are aware enough about the patient safety, care, and code of conduct with their patients in the interventional radiology department. Objective: This article aims to measure the awareness of radiologists and radiographers toward care and safety in an interventional radiology department. Material and Method: This study was carried in period from 15 February to 20 April 2022. One hundred sixty-four radiographers and radiologists participating in this study completed the questionnaire, which equals a response rate of approximately 82%. The questionnaire was fully completed by almost all responders;only a few of them gave partial answers. Results: The first question for radiographers and radiologists was “the sufficient awareness about the patient safety and care during the interventional radiology procedure. Also, the majority of the radiographers and radiologists are providing the patients with sufficient information when he/she ask for help or queries. A large number of radiographers and radiologists were participating in this study explaining the procedures to patients before starting the examinations in a structured way. Finally, the result shows both radiographers and radiologists respect the patient’s rights, privacy, and dignity and also kept the radiation protection during the interventional radiology procedures. Conclusion: This article summarizes the key categories of awareness of patient care issues in the provision of interventional radiology services, from the joint perspectives of radiographers and radiologists, and provides references for further reading in all major relevant areas.展开更多

It is well-known that Professor Lin Gui is the founding father of Interventional radiology. Under the leadership of Lin Gui and other professors, interventional therapy of liver cancer has swiftly progressed in China. Indeed, TAI, TAE, TACE and ablation therapy have witnessed great innovations in hardware facil ities, technical means, and therapeutic philosophy, while incorporating Chinese characteristics. As with the development of combined interventional therapy in China, interventional treatment of liver cancer has gradually started the process of precision and individualization. Actually, multidisciplinary, multimodal, and polymorphic treatments will be the most suitable pattern for liver cancer in the future, among which combination of interventional therapy with targeted, immunological treatments and information technology(IT) tools may bring a revolutionary breakthrough in liver cancer treatment.展开更多

文摘Interventional radiological procedures performed under the guidance of X-ray imaging tools are widely used to diagnose and treat various conditions.However,radiation exposure can result in many health problems,including cataracts,skin necrosis,radiation burns,hair loss,birth defects,and cancer^([1-2]).Patient exposure during an interventional radiology procedure involves a wide dose range and can reach a level at which deterministic effects may occur^([3]).Although knowledge of radiation safety has greatly improved over the past century,radiation exposure in the healthcare environment remains a risk to both patients and medical professionals.Recently,given the increasing number of interventions and complexity of cases,there has been growing concern about the radiation exposure of patients and surgical personnel.Therefore,a special evaluation of the exposure of patients and medical staff is necessary to ensure their protection.
文摘An infant with Kasabach-Merritt Phenomenon(KMP)presented with a giant subcutaneous mass in the right lower limb,severe hypofibrinogenemia,and thrombocytopenia.Glucocorticoids,along with supportive treatments including transfusion of blood products and clotting factors,were administered to reverse fatal disseminated intravascular coagulation and acute hemolysis.The glucocorticoid dose was tapered slowly,and sirolimus was added to treat the hemangiomas.The patient subsequently underwent interventional therapy.After 6 months of medical and interventional therapy,the patient was doing well with a normal platelet count,the tumor volume was markedly reduced,and the primary cutaneous lesion became pale pink.Currently,the patient remains on sirolimus,and no recurrence of thrombocytopenia or further growth of the mass was observed after six months of follow-up.

文摘Magnesium is generally known to degrade in aqueous environments by an electrochemical reaction.The corrosion products of magnesium include hydrogen gas,Mg^(2+),and Mg(OH)_(2).Here,we summarize the published literature describing the corrosion characteristics of magnesium,and the antitumor properties of magnesium-associated corrosion products,aiming to induce the therapeutic properties of magnesium and magnesium alloys in solid tumors.The therapeutic potential of corrosion products of magnesium is enormous.Hydrogen gas exhibits antioxidant and anti-inflammatory properties,which amount to potential anti-tumor characteristics.Mg(OH)_(2),which creates a localized alkaline microenvironment,represents a second approach for anti-tumor therapy with magnesium metal.Upregulated concentrations of Mg^(2+)ions in the local tumor microenvironment remodelling are considered a third approach for anti-tumor therapy.Therefore,we speculate about the different physical forms of magnesium that could create an anti-tumor microenvironment upon tumor interventional therapy,a technique that precisely places anti-tumor implants like particles and stents.Finally,we present our viewpoints on the potential use of magnesium in diverse solid tumor therapies to inhibit tumor progression.
文摘Objective:To observe the clinical effect of emergency interventional therapy for patients with acute severe non-variceal upper gastrointestinal bleeding.Methods:78 patients with acute severe non-variceal upper gastrointestinal bleeding who were treated in the General Hospital of the Eastern Theater Command from May 2020 to May 2023 were randomly divided into two groups according to different treatment plans.The study group underwent emergency upper gastrointestinal angiography and interventional embolization therapy,the control group was treated with esomeprazole;the clinical data related to the two groups were compared,including the total effective rate of treatment,blood pressure stabilization time,bleeding control time,etc.Results:The effective rate of clinical treatment in the study group was 97.44%,which was higher than that in the control group,which was 79.49%(P<0.05).Both were significantly shorter(P<0.05);the 7 d rebleeding rate and 30 d rebleeding rate of the study group were lower than those of the control group(P<0.05);the 7 d and 30 d mortality rates of the two groups after treatment were compared,and the comparative study group was lower,but there was no significant difference(P>0.05).Conclusion:Emergency interventional therapy can control bleeding more quickly,shorten bleeding control time and complete hemostasis time,shorten blood pressure stabilization time and abdominal pain relief time,and reduce rebleeding rate in patients with acute severe non-variceal upper gastrointestinal bleeding.

文摘The recent interest in precision medicine among interventionists has led to the establishment of the concept of precision interventional radiology(PIR).This concept focuses not only on the accuracy of interventional operations using traditional image-guided techniques,but also on the comprehensive evaluation of diseases.The invisible features extracted from CT,MRI,or US improve the accuracy and specificity of diagnosis.The integration of multi-omics and molecule imaging provides more information for interventional operations.The development and application of drugs,embolic materials,and devices broaden the concept of PIR.Integrating medicine and engineering brings new image-guided techniques that increase the efficacy of interventional operations while reducing the complications of interventional treatment.In all,PIR,an important part of precision medicine,emphasizing the whole disease management process,including precision diagnosis,comprehensive evaluation,and interventional therapy,maximizes the benefits of patients with limited damage.
文摘Background: The hospitals and health care centres are organized around the patient, a model in which healthcare providers partner with patients and families to identify and satisfy patients’ needs and preferences. Providers respect patients’ values and preferences, address their emotional and social needs, and involve them and their families in decision making. According to the best of our knowledge, there is no evidence to prove, radiologists and radiographers are aware enough about the patient safety, care, and code of conduct with their patients in the interventional radiology department. Objective: This article aims to measure the awareness of radiologists and radiographers toward care and safety in an interventional radiology department. Material and Method: This study was carried in period from 15 February to 20 April 2022. One hundred sixty-four radiographers and radiologists participating in this study completed the questionnaire, which equals a response rate of approximately 82%. The questionnaire was fully completed by almost all responders;only a few of them gave partial answers. Results: The first question for radiographers and radiologists was “the sufficient awareness about the patient safety and care during the interventional radiology procedure. Also, the majority of the radiographers and radiologists are providing the patients with sufficient information when he/she ask for help or queries. A large number of radiographers and radiologists were participating in this study explaining the procedures to patients before starting the examinations in a structured way. Finally, the result shows both radiographers and radiologists respect the patient’s rights, privacy, and dignity and also kept the radiation protection during the interventional radiology procedures. Conclusion: This article summarizes the key categories of awareness of patient care issues in the provision of interventional radiology services, from the joint perspectives of radiographers and radiologists, and provides references for further reading in all major relevant areas.
文摘Routine chest radiography is not a requirement in post-surgery cardiac bypass patients.However,the safety of abandoning routine chest radiographs in critically ill patients remains uncertain.Surgery in an asymptomatic coronavirus disease 2019(COVID-19)patient presents additional challenges in postoperative management.Chest radiography remains a valuable tool for assessment of all patients,even a stable one.Management of surgical patients as an emergency in an asymptomatic COVID-19 case remains a surgeon’s dilemma.
文摘Fast neutron radiography(FNR) is an effective non-destructive testing technique.Due to the scattering effect and low detection efficiency,the detection limit of FNR under certain conditions cannot be determined.In order to obtain the minimum detectable thickness by FNR,we studied the contrast sensitivity of FNR lead samples,both theoretically and experimentally.We then clarified the relationship between pixel value and irradiation time,and sample materials and thickness.Our experiment,using a4-cm-thick lead sample,verified our theoretical expression of FNR contrast sensitivity.
文摘In China interventional therapy of liver cancer started in the 1980s. It is well-known that Professor Lin Gui is the founding father of Interventional radiology. Under the leadership of Lin Gui and other professors, interventional therapy of liver cancer has swiftly progressed in China. Indeed, TAI, TAE, TACE and ablation therapy have witnessed great innovations in hardware facil ities, technical means, and therapeutic philosophy, while incorporating Chinese characteristics. As with the development of combined interventional therapy in China, interventional treatment of liver cancer has gradually started the process of precision and individualization. Actually, multidisciplinary, multimodal, and polymorphic treatments will be the most suitable pattern for liver cancer in the future, among which combination of interventional therapy with targeted, immunological treatments and information technology(IT) tools may bring a revolutionary breakthrough in liver cancer treatment.

文摘It is an era of diagnostic and interventional ultrasound (US).Various new techniques such as three-dimensional US(3D US),interventional US,and contrastenhanced US(CEUS)have been introduced into clinical practice.Dr.Xu and his colleagues have taken advantage of these techniques and carried out a series of relevant studies.Their use of 3D US in the liver,gallbladder,liver tumor volumetry,guidance for ablation,and 3D CEUS has widened the application of 3D US in the clinic.They found that prognosis in patients with hepatocellular carcinoma(HCC)after thermal ablation with curative intent was determined by treatment response to ablation,pretreatment serum AFP,and liver function reserve.Tumor response to treatment was the most predictive factor for long-term survival.They compared the use of percutaneous microwave ablation and radiofrequency ablation for the treatment of HCC and found that both are effective methods in treating HCCs.The local tumor control,complications related to treatment, and long-term survival were equivalent for the two modalities.They first compared the enhancement patterns of HCC and intrahepatic cholangiocarcinoma(ICC)and proposed the diagnostic clues for ICC,liver angiomyolipoma(AML),gallbladder cancer,renal carcinoma,and renal AML,which have greatly enhanced the role ofCEUS in the clinic.They also evaluated the diagnostic performance of CEUS in characterizing complex cystic focal liver lesions and the agreement between two investigators with different experience levels;and found that CEUS is especially useful for the young investigator.They assessed the effect of anti-angiogenic gene therapy for HCC treated by microbubble-enhanced US exposure and concluded that gene therapy mediated by US exposure enhanced by a microbubble contrast agent may become a new treatment option for HCC.
