To investigate the causal relationship between ever smoked and frozen shoulder using a Mendelian randomization (MR) approach. Pooled data from a large-scale genome-wide association study were used. Genetic loci that were independent of each other and associated with ever smoked and frozen shoulder in populations of European ancestry were selected as instrumental variables. ⋯ Inverse variance weighting results of ever smoked showed an OR = 2.49, 95% CI = 1.05-5.91, P = .038, indicating that ever smoked is a risk factor for a frozen shoulder. And the test revealed no heterogeneity and pleiotropy, and the sensitivity analysis also showed robust results. This study used two-sample MR analysis to analyze and explore the genetic data, and the results showed a higher prevalence of frozen shoulder in patients with ever smoked, suggesting that active control of ever smoked may reduce the occurrence of frozen shoulder.

Diabetic nephropathy (DN) is a major microvascular complication of diabetes mellitus that leads to end-stage renal disease. Hyperglycemia triggers apoptosis and kidney damage. Milk fat globule-epidermal growth factor 8 (MFG-E8) and TAM receptor tyrosine kinases, Tyro3, Axl, and Mer, are phagocytic receptors that mediate the clearance of apoptotic cells. This study aimed to identify the role of MFG-E8 and TAM receptors in the development of DN. ⋯ Decreased MFG-E8 and TAM receptor expression is associated with an increased risk of microvascular complications in patients with T2DM, which plays a critical role in the diagnosis of diabetic patients with microvascular complications, especially early stage DN, and in monitoring the development of DN.

This study aims to elucidate and examine the intricate interrelation between 5,10-methylenetetrahydrofolate reductase (MTHFR), combined folic acid (FA), and trace element supplementation as a preventive strategy against fetal malformations during the inaugural trimester of pregnancy. Eighty pregnant women selected from our hospital's early obstetrics department from May 2021 to August 2021. Pregnant women are divided into the MTHFR combined group, FA, and trace element group. ⋯ The deformity rate was negatively correlated with FA and trace elements. Pregnant women in the first trimester may have fetal malformations, and the malformation rate is negatively correlated with FA and positively correlated with MTHFR level. Importantly, the inverse relationship between FA supplementation and malformation incidence underscores its significance as a preventive measure.

Primary hepatic neuroendocrine tumors are rarely reported and extremely blurry to diagnose, especially in the case of a confirmed diagnosis of colon cancer and a family history. Here we report such a case followed by our experiences and lessons. ⋯ Hepatic neuroendocrine tumors exhibited no specific symptoms, signs or imaging manifestations, mainly relying on immunohistochemistry for diagnosis, which makes it difficult to be distinguished from other liver masses and metastatic tumors, especially interfered by a confirmed diagnosis of colon cancer and a family history. In this regard, more rigorousness is required in the diagnosis and treatment of liver tumors.

This study aims to investigate the causal effect of Alzheimer disease on thyroiditis using medical English and the Nature journal style. Genome-wide association data for Alzheimer disease and thyroiditis were obtained from the Mendelian Randomization (MR) platform. Single nucleotide polymorphisms (SNPs) significantly associated with Alzheimer disease were identified and used as instrumental variables (IVs) to examine the causal relationship between Alzheimer disease and thyroiditis, employing a 2-sample MR study design. ⋯ Upon evaluation using different methods, a consistent association between Alzheimer disease and thyroiditis was observed inverse variance-weighted method [IVW]: odds ratio [OR] 1.32, 95% confidence interval [CI] 1.01-1.72; weighted median estimator: OR 1.32, 95% CI 1.01-1.72; Mendelian randomization Egger regression: OR 1.29, 95% CI 0.92-1.81), indicating a positive correlation between Alzheimer disease and increased risk of thyroiditis. There was no evidence suggesting that the observed causal relationship between Alzheimer disease and thyroiditis risk could be influenced by pleiotropy (Mendelian randomization Egger intercept 0.0058, P = .88. Our MR analysis reveals causal association of Alzheimer disease and thyroiditis, despite observational studies reporting an association between Alzheimer disease and thyroiditis.
