Article Synopsis
  • Immune checkpoint inhibitors (ICIs) have transformed cancer treatment, but many patients still show low response rates, presenting ongoing challenges.
  • The study found that Sema4A-positive non-small cell lung cancer (NSCLC) patients had a significantly better response to anti-PD-1 therapy compared to those who were Sema4A-negative.
  • Sema4A enhances T cell activation and prevents T cell exhaustion in NSCLC, making it a potential target for improving ICI treatments and a useful biomarker for predicting patient response.

Background: Previous trials suggest that older adults with non-small cell lung cancer (NSCLC) derive benefit from platinum doublet combination therapy, but its superiority is controversial. Although geriatric assessment variables are used to assess the individual risk of severe toxicity and clinical outcomes in older patients, the standard first-line treatment is still debated. Therefore, we aimed to identify the risk factors for clinical outcomes in older patients with NSCLC.

The Special Committee for Measures Against Transition from Pediatric to Adult Health Care of the Japanese Society of Neurology, which consists of child and adult neurologists, started to tackle the issues of pediatric to adult health care transition for patients with neurological disease in July 2020. The Committee held a workshop with a theme of "cooperation between child and adult neurologists," which is a critical issue in the pediatric to adult health care transition. To solve the many problems in the pediatric to adult health care transition, it is crucial that child and adult neurologists and primary care physicians cooperate on the following issues: preparing child neurologists for the transition, encouraging adult neurologists to study child neurology, promoting the formation of multidisciplinary teams, improving the medical system and medical fees, appealing to governmental agencies for issues of community health care and welfare services.

Background: Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant muscular disorder characterized by asymmetric muscle wasting and weakness. FSHD can be subdivided into two types: FSHD1, caused by contraction of the D4Z4 repeat on chromosome 4q35, and FSHD2, caused by mild contraction of the D4Z4 repeat plus aberrant hypomethylation mediated by genetic variants in SMCHD1, DNMT3B, or LRIF1. Genetic diagnosis of FSHD is challenging because of the complex procedures required.
