Objectives: Checkpoint inhibitors pneumonitis (CIP) is one of the most lethal adverse events in non-small cell lung cancer (NSCLC) patients treated with immune checkpoint inhibitors (ICIs). Currently, there is no recognized and effective predictive model to predict CIP in NSCLC.
Materials And Methods: This study retrospectively analyzed 460 NSCLC patients who were first treated with ICIs. Patients were divided into three cohorts based on the occurrence of CIP: any grade CIP cohort, grade ≥ 2 CIP cohort and grade ≥ 3 CIP cohort.
Results: A dynamic hypertension nomogram was constructed with elements including hypertension, interstitial lung disease (ILD), emphysema at baseline, and higher baseline platelet/lymphocyte ratio (PLR). The C indices of the training cohort and the internal and external validation cohort in any grade CIP cohort were 0.872, 0.833 and 0.840, respectively. The constructed hypertension nomogram was applied to grade ≥ 2 cohort and grade ≥ 3 cohort, and their C indices were 0.844 and 0.866, respectively. Compared with the non-hypertension nomogram, the hypertension nomogram presented better predictive power.
Conclusions: After validated by internal and external validation cohorts, the dynamic online hypertension has the potential to become a convenient, intuitive, and personalized clinical tool for assessing the risk of CIP in NSCLC patients.

It is crucial to accurately identify patients with cancer at high risk for immune-related adverse events (irAEs) caused by immune checkpoint inhibitors (ICIs). The present retrospective study analyzed the risk factors for irAEs in 992 patients with cancer treated with ICIs at Xi'an International Medical Center Hospital from December 2021 to December 2023. The patients were categorized into one group that experienced irAEs (n=276) and a control group (n=716) based on the occurrence of irAEs.

Background: There is a lack of suitable predictive markers for assessing the efficacy of amlodipine in treating children with primary hypertension. This study aimed to explore whether plasma calcitonin gene-related peptide (CGRP) and nitric oxide (NO) could predict the effectiveness of amlodipine in pediatric primary hypertension.
Methods: This study enrolled 74 children and adolescents with primary hypertension who were prescribed amlodipine monotherapy, and after 4 weeks of treatment, they were divided into responders and non-responders according to blood pressure.

Objectives: To identify independent risk factors for perioperative hidden blood loss (HBL) in intertrochanteric femoral fractures (ITFs) and to develop a predictive model.
Methods: We enrolled 231 patients with ITFs who underwent proximal femoral nail antirotation (PFNA) surgery at the Orthopedics Department of Northern Jiangsu People's Hospital, Jiangsu Province, China, from January 2021 to December 2023. Hidden blood loss was calculated using the OSTEO formula, and independent risk factors were screened using the Least Absolute Shrinkage and Selection Operator (LASSO) logistic regression.

Background: Intrahepatic and perihepatic abscess (IPHA) is a severe yet understudied complication that can occur after hepatectomy. This multicenter study aimed to elucidate the clinical features, risk factors, and outcomes of IPHA after hepatectomy for hepatocellular carcinoma (HCC), and to develop a novel prediction model for personalized risk assessment.
Methods: This was a multicenter cohort study of HCC patients who underwent curative-intent hepatectomy.
