We analyzed mortality (all-cause and lung cancer-specific) and time to follow-up treatment in stage I and II non-small cell lung cancer (NSCLC) patients treated with photodynamic therapy (PDT) compared with ablation therapy and radiation therapy. From Surveillance, Epidemiology, and End Results-Medicare linked data, patients diagnosed with stage I and II NSCLC between 2000 and 2015 were identified. Outcomes were mortality (overall and lung cancer-specific) and time to follow-up treatment. ⋯ Among stage I and II NSCLC patients, PDT was associated with improved survival, compared with radiation alone; and longer time to follow-up treatment compared with ablation. Currently, PDT is offered in various combinations with surgery and radiation. Larger studies can investigate the efficacy and effectiveness of these combinations.

Physical activities, such as resistance training and walking, are known to be effective against chronic low back pain (CLBP). However, few studies have examined the associations of walking and resistance training with CLBP in the general older population. Therefore, this study analyzed these relationships in the older Korean population (aged ≥65 years), with the goal of determining which exercise is better for CLBP. ⋯ In this cross-sectional study, walking was associated with a lower risk of CLBP. In particular, walking >5days per week had the maximum benefit in a lower risk of CLBP. Therefore, clinicians can consider recommending walking to patients with CLBP for optimal pain improvement.

Pseudotumor formation after hip arthroplasty is a rare complication that can occur not only at the head-neck junction but also at the modular neck-stem junction. Dislocation is a challenging and common complication of primary and revision total hip arthroplasty compared with other complications. Similarly, the association between pseudotumors and delayed recurrent dislocation remains unclear. ⋯ The application of the modular-neck stem should be cautiously performed, particularly for modular prostheses containing different alloys. Pseudotumors and insufficient soft-tissue tension both contribute to hip instability, which may eventually lead to delayed repeated dislocation. In addition, femoral offset must be considered. Cement-liner technology may be used for aging patients who are less active. This case report, focusing on pseudotumors and delayed recurrent dislocations, aimed to identify factors that may support this diagnosis, which is easy to miss. Consequently, it can provide further details on the treatment process and alert orthopedic surgeons to this infrequent but important cause of delayed recurrent dislocation.

This was a national database study. To examine the role of comorbidities and demographics on inpatient complications in patients with lumbar degenerative conditions. Degenerative conditions of the lumbar spine account for the most common indication for spine surgery in the elderly population in the United States. ⋯ Females, Medicare insurance status, Medicaid insurance status, urban hospital locations, and certain geographical locations were found to predict postoperative complications (P < .001). There were substantial differences in surgical management and postoperative complications among individuals of different sex, races, and insurance status. Further investigation evaluating the effect of demographics in spine surgery is warranted to fully understand their influence on patient complications.

Esophageal stenosis after chemotherapy in breast cancer patients is rare. Distinguishing esophageal stenosis from esophageal metastasis caused by breast cancer is important. ⋯ Esophageal stenosis is very infrequent in patients with breast cancer after chemotherapy. It needs to be. distinguished from esophageal metastasis caused by breast cancer. Esophageal stent implantation may provide benefits in terms of both symptom control and survival in patients with severe esophageal structures.
