Background: Carinal resections for non-small cell lung cancer (NSCLC) invading the carina are challenging cases that require a therapeutic strategy. The aim of this study was to compare the oncologic outcomes and complications of patients who underwent carinal resection.
Methods: Sixty-four patients who underwent carinal resection between 2005 and 2016 were evaluated. Data were retrospectively reviewed for indications, complications, and factors influencing long-term survival.
Results: The study included 51 patients (79.7%) who underwent sleeve pneumonectomy (sP) and 13 patients who underwent carinal sleeve lobectomy (csL) as a curative therapy. Nine patients (14.1%) received induction chemotherapy. Complications were observed in 31 patients (48.8%), including 24 patients (47.1%) in the sP group and 7 patients (53.8%) in the csL group ( = 0.662). Six patients (9.4%) developed bronchopleural fistula. The 30-day mortality rate was 10.9% ( = 7). The 5- and 10-year survival rates were 42.2 and 23.1%, respectively. N2 and R1 were identified as factors affecting survival ( = 0.029 and = 0.047).
Conclusion: Carinal resections have acceptable morbidity, mortality, and long-term survival outcomes in central NSCLC. The main factors affecting survival are complete resection and nodal status. The results of csL were similar to those of sP. Therefore, we believe that csL should be performed in all eligible patients.

Background: The global incidence of infertility is increasing, and infertility has become an important medical and social issue. With the widespread application of in vitro fertilization-embryo transfer (IVF-ET) technology, the mental health problems of patients undergoing this treatment have gradually attracted widespread attention. The purpose of this study was to explore the relationships among the level of hope, the fertility quality of life and negative emotions of patients who underwent IVF-ET treatment for the first time to provide a scientific basis for subsequent psychological support interventions.

Background: Increased glucagon levels are now recognized as a pathophysiological adaptation to counteract overnutrition in type 2 diabetes (T2D). This study aimed to elucidate the role of glucagon in peripheral nerve function in patients with T2D with different body mass indices (BMIs).
Methods: We consecutively enrolled 174 individuals with T2D and obesity (T2D/OB, BMI ≥ 28 kg/m), and 480 individuals with T2D and nonobesity (T2D/non-OB, BMI < 28 kg/m), all of whom underwent oral glucose tolerance tests to determine the area under the curve for glucagon (AUC).

Background: The ultimate goal of arthroplasty is thought to be the ability to "forget" a joint implant in daily activities. The Forgotten Joint Score (FJS-12), a score system that evaluates how much patients have been able to forget their hip or knee prosthesis, was recently published. It is based on a self-administered questionnaire that consists of 12 items.

Background: Hepatic glycogen storage diseases (GSD) are inborn errors of metabolism with abnormal storage or utilization of glycogen, a complex disease with significant genetic heterogeneity and similar clinical manifestations. This study aimed to describe the gastrointestinal symptoms and endoscopic features of hepatic GSD, including types Ia, Ib, III, VI, and IX, to provide evidence for etiology and treatment.
Methods: A national cohort survey questionnaire was distributed to patients diagnosed with GSD type Ia, Ib, III, VI, and IX through genetic testing or their parents in mainland China in May 2022.
