Background: Platelet antigens can stimulate the body to produce platelet alloimmune antibodies through blood transfusion, pregnancy, and autoimmunity. In the blood of pregnant women, anti-platelet antibodies can cause embryo implantation failure, abortion, etc. if they are present.
Methods: The platelet antibody was screened in 326 infertile patients (282 primary infertility and 44 secondary infertility) and 522 healthy controls in the physical examination center of our hospital by solid phase agglutination of red blood cells.
Results: The positive rate of anti-platelet antibody was 9.51% in the infertility group and 2.30% in the healthy control group. There was a significant difference between them (χ2 = 4.51, p < 0.05). The positive rate of anti-platelet antibody in the infertility group was significantly higher than that in the control group. The positive rate of anti-platelet antibody in the secondary infertility patients was significantly higher than that in the primary infertility patients (χ2 = 1.62, p < 0.05), and the positive rate of serum anti-platelet antibody increased gradually with the increase of infertility years.
Conclusions: The positive rate of anti-platelet antibody is closely related to infertility and gradually increases with the age of infertility.

Association between estrogen and kidney function: population based evidence and mutual bidirectional Mendelian randomization study.
Clin Exp Nephrol

Department of Nephrology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine, Shanghai, China.
Background: Previous studies have suggested a potential role of estrogen in the pathophysiology of chronic kidney disease (CKD); however, the association and causality between estrogen and kidney function remain unclear.
Methods: The cross-sectional correlation between serum estradiol concentration and estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) was analyzed using data from the National Health and Nutrition Examination Survey 2013-2016. Causality was tested using mutual bidirectional Mendelian randomization (MR) approaches based on six large-scale GWAS studies.
Ritlecitinib, a JAK3 /TEC inhibitor, modulates the markers of celiac autoimmunity in alopecia areata and vitiligo patients.
Arch Dermatol Res
January 2025
Division of Gastroenterology and Hepatology, 200 1st Street SW, Rochester, MN, 55905, USA.
Background: Celiac disease (CeD) has shown an association with autoimmune disorders including vitiligo and alopecia areata (AA). Ritlecitinib, a JAK3 and TEC kinase family inhibitor, has been approved for treatment of patients with AA and is in late-stage development for vitiligo. Ritlecitinib inhibits cytotoxic T cells, NK cells, and B cells which play a role in the pathogenesis of CeD.

Background: The standard first-line treatment for human epidermal growth factor receptor 2 (HER2)-positive recurrent/metastatic breast cancer currently includes pertuzumab plus trastuzumab and docetaxel. This study aimed to evaluate the effectiveness of KN026, an anti-HER2 bispecific antibody, plus docetaxel in first-line treatment of HER2-positive recurrent/metastatic breast cancer.
Methods: This open-label, single-arm, phase II study enrolled patients with HER2-positive recurrent/metastatic breast cancer in 19 centers across China from December 30, 2019 to May 27, 2021.

Background: Neck pain is common among people with headache, including migraines, tension headache, and cervicogenic headache. Neck pain has also been associated with self-reported sinus headache in individuals who were not formally diagnosed with headache attributed to rhinosinusitis (HAR). Neck pain, in individuals diagnosed with HAR according to the International Classification of Headache Disorders, has not been investigated.
