Objective: Postoperative venous thromboembolism (VTE) is a potentially life-threatening complication. This study aimed to develop a predictive model to identify independent risk factors and estimate the likelihood of VTE in patients undergoing surgery for cervical cancer.

Methods: We conducted a retrospective cohort study involving 1,174 patients who underwent surgery for cervical carcinoma between 2019 and 2022.

Background: With advancements in healthcare, traditional VTE risk assessment tools are increasingly insufficient to meet the demands of high-quality care, underscoring the need for innovative and specialized assessment methods.

Objective: Owing to the remarkable success of machine learning in supervised learning and disease prediction, our objective is to develop a reliable and efficient model for assessing VTE risk by leveraging the fundamental data and clinical characteristics of colorectal cancer patients within our medical facility.

Methods: Six commonly used machine learning algorithms were utilized in our study to predict the occurrence of VTE in patients with rectal cancer.

Article Synopsis
  • Lung cancer is the most common and deadliest cancer in China, with non-small cell lung cancer (NSCLC) making up 80-85% of cases, and immune checkpoint inhibitors (ICIs) are now standard first-line treatments for it.
  • A study of 1,321 NSCLC patients from Chongqing University Cancer Hospital aimed to develop a nomogram model to predict patient outcomes based on demographic, clinical, and laboratory factors observed during immunotherapy.
  • The final model identified 11 key prognostic factors affecting overall survival, achieving a C-index of approximately 0.717 for the training cohort, indicating good accuracy in predicting survival outcomes.

Objective: The incidence of venous thromboembolism (VTE) is significantly elevated in breast cancer patients, with a three-to-fourfold increase, and further escalates to sixfold in those undergoing chemotherapy. This study aims to identify the risk factors for VTE and develop a Nomogram risk prediction model distinct from the traditional Khorana score.

Methods: Univariate Cox regression analysis assessed the impact of each variable on the occurrence of VTE, while stepwise multivariate Cox regression analysis identified independent predictors.

Article Synopsis
  • Venous thromboembolism (VTE) is a serious complication that increases mortality rates in patients with primary liver cancer (PLC), prompting the need for better prediction methods.* -
  • A study analyzed 1,565 PLC patients to identify eight key risk factors for VTE using logistic regression, leading to the development of a nomogram model.* -
  • The nomogram demonstrated strong predictive accuracy and clinical utility, helping identify high-risk patients for timely interventions to mitigate thrombotic risks.*

Objective: Venous thromboembolism (VTE) poses a significant threat to lung cancer patients, particularly those receiving treatment with immune checkpoint inhibitors (ICIs). We aimed to develop and validate a nomogram model for predicting the occurrence of VTE in lung cancer patients undergoing ICI therapy.

Methods: The data for this retrospective cohort study was collected from cancer patients admitted to Chongqing University Cancer Hospital for ICI treatment between 2019 and 2022.

Background: To evaluate the efficacy of modified uterine stent in the treatment of mild-to-moderate intrauterine adhesions and explore the relative indicators affecting prognosis prediction.

Methods: A total of 115 patients with mild-to-moderate intrauterine adhesions received a modified uterine stent placement after hysteroscopy adhesiolysis. The second-look hysteroscopy operated after 3 months surgery, and the third-look hysteroscopy operated after 6 months surgery if necessary.

Background: The global aging phenomenon has raised concerns about the cognitive abilities of older individuals. This study aimed to explore the relationship between social participation, depressive symptoms, and cognitive function among middle-aged and older adults.

Methods: This study utilized data from the China Longitudinal Study of Health and Retirement (CHARLS) from wave 1 to wave 4.

Article Synopsis
  • A study was done to help lymphoma patients on chemotherapy by creating a special model that predicts their risk of getting blood clots (VTE).
  • Researchers looked at data from lymphoma patients in China and found important factors like age and blood test results that affect this risk.
  • The new model is reliable and can help doctors identify patients who are at higher risk so they can give them the right preventive care.

Background: Major depressive disorder (MDD) is a highly heterogeneous mental illness and a major public health problem worldwide. A large number of observational studies have demonstrated a clear association between MDD and coronary heart disease (CHD), and some studies have even suggested that the relationship is bidirectional. However, it was unknown whether any causal relationship existed between them and whether causality was bidirectional in such an instance.

Objective: Cervical cancer has one of the highest incidence and mortality rates of any malignant tumor of the female reproductive tract, and its longer treatment period will place significant financial strain on patients and their families. Little is known about how health insurance policies influence cervical cancer prognosis, particularly in developing countries. The relationship between cervical cancer specific death and cervical cancer all-cause mortality with public health insurance, self-payment rate, and the combined effect of public health insurance and self-payment rate was investigated in this study.

Stomach cancer (GC) has one of the highest rates of thrombosis among cancers and can lead to considerable morbidity, mortality, and additional costs. However, to date, there is no suitable venous thromboembolism (VTE) prediction model for gastric cancer patients to predict risk. Therefore, there is an urgent need to establish a clinical prediction model for VTE in gastric cancer patients.
