Increasing evidence has suggested a strong association of Q223R (rs1137101) and K109R (rs1137100) polymorphisms in leptin receptor (LEPR) gene with susceptibility of breast cancer (BC), but inconsistent results were obtained. To provide a quantitative assessment of this association, a systematic review and meta-analysis was performed. ⋯ The available evidence suggests that Q223R polymorphism may be significantly associated with BC risk in African population. K109R polymorphism may be significantly associated with BC risk in Asian population.

Gastric adenosquamous carcinoma (GASC) is a rare subtype of gastric cancer. Research on GASC treatment is limited, and its outcome is usually poor. We investigated the clinical features, immunoprofile of GASC, and determined the optimal treatment modality for these patients. ⋯ Patients with GASC are more likely to yield positive results for CPS and dMMR. Biomarkers should be examined, and immunotherapy can be considered as frontline systemic treatment.

This study aimed to analyze the demographic characteristics and prognostic factors of malignant peripheral nerve sheath tumor (MPNST) in a Taiwanese population. Single-center treatment outcomes were also presented. ⋯ In our series, metastasis diagnosed at presentation, large lesion sizes, and recurrence were identified as significant poor prognostic factors of survival. Metastasis was also identified as the only significant risk factor of recurrence. NF1-associated MPNSTs presented with significantly larger tumor sizes and additional treatment postoperatively did not significantly improve survival. The limitations of this study include its retrospective nature and sample size.

Birth defects (BDs) are the main causes of mortality and disability in infants and children. Associations between maternal diabetes mellitus (DM), including gestational DM (GDM) and pregestational DM (type 1 or type 2), and the risk of BDs have been reported. This study aims to determine the relationship between maternal DM and BDs and to investigate whether reducing the incidence of DM can decrease the incidence of BDs. ⋯ Mothers with pregestational DM (type 1 or type 2) increase the incidence of BD. Appropriate maternal glycemic control may achieve good pregnancy and perinatal outcomes.
