Article Abstract
Background: Non-small cell lung cancer (NSCLC) remains a significant challenge for public health and is closely associated with malnutrition; however, few studies have attempted to examine the malnutrition experienced by patients with driver gene-negative NSCLC who have undergone combined chemotherapy after surgery. This study aimed to evaluate the nutritional status of patients with driver gene-negative NSCLC who received adjuvant chemotherapy after surgery and examined the application value of three nutritional screening tools: Nutritional Risk Screening Scale 2022 (NRS-2002), the Prognostic Nutritional Index (PNI), and the Patient-Generated Subjective Global Assessment Scale (PG-SGA).
Methods: Data from patients with driver gene-negative NSCLC who underwent sleeve surgery and adjuvant chemotherapy at Shanghai Pulmonary Hospital from January 2021 to December 2021 were prospectively collected. The NRS-2002, PG-SGA, and PNI were used to assess the risk of malnutrition in patients. The correlation between the three nutritional screening tools and various nutritional indicators was analyzed, and the diagnostic efficacy of the three nutritional screening tools was compared using the Global Leadership Initiative on Malnutrition as the gold standard for malnutrition assessment (diagnosis).
Results: There was a correlation between the three nutritional screening tools and human body composition and blood biochemical indicators (P<0.05), and the composite correlation coefficient between PNI and various nutritional indicators was the highest (r=0.683; P<0.001). In the evaluation of diagnostic efficacy, PG-SGA demonstrated the highest sensitivity and accuracy index of 85.70% and 54.00%, respectively, while the NRS-2002 had the highest specificity at 71.30%.
Conclusions: All three nutritional screening tools can provide a basis for diagnosing malnutrition in patients with driver gene-negative NSCLC after postoperative adjuvant chemotherapy, and their combined application in clinical practice can more comprehensively reflect the nutritional status of these patients.

IntroductionThe rapid expansion of virtual ambulatory care has included both video and audio-only modalities. The impact of visit modality on patient experience is poorly understood, particularly in the interplay with social health determinants and technical aspects of virtual care. We sought to characterize differences in the patient-reported experience of virtual care between video and audio-only modalities, and to understand drivers of these differences.

Hypertension is a clinical condition associated with an increase in cardiovascular morbidity and mortality. In chronic kidney disease (CKD), hypertension is also a driver of faster disease progression. Correct and appropriate treatment with antihypertensive medication reduces the risk of cardiovascular events and slows kidney disease progression.

Myoepithelial carcinoma (MECA) is a malignant neoplasm composed exclusively of myoepithelial cells and accounts for less than 1% of all salivary gland tumors. Its diagnosis is often challenging due to histologic overlaps with benign lesions and its variable morphologic presentation. Although molecular profiling has emerged as a valuable tool in salivary gland tumor classification, the genetic landscape of MECA remains incompletely defined.

Background: Stroke persists as the second leading global cause of mortality and disability. We analyzed G20 nations using Global Burden of Disease (GBD) 2021 data (1990-2021) to provide a new perspective.
Methods: We obtained age-standardized rates (ASR) of stroke mortality, incidence, prevalence, and YLLs (years of life lost) across G20 nations.

Objective: To determine the distribution of the cesarean section (CS) rate according to the Robson's 10-group classification system (RTGCS) and identify which groups contribute most to the rising CS rate at the concerned institute.
Methods: A cross-sectional single-center study was conducted between April and September 2021. Data were extracted from patients and entered into a structured template in accordance with RTGCS criteria.
