Erectile dysfunction (ED) is a common problem that seriously impacts men's quality of life and mental health. Earlier studies have indicated that homocysteine (HCY) levels might be linked to the risk of ED, although these studies are limited by small sample sizes and insufficient correction for confounding factors. This study uses data from the 2001-2004 National Health and Nutrition Examination Survey (NHANES) to evaluate the relationship between HCY levels and ED risk in U.S. adult males. The analysis involved using a weighted generalized linear model to assess main effects and restricted cubic splines (RCS) to explore nonlinear relationships. Results showed that the association between HCY and ED was not statistically significant after adjusting for covariates. However, interaction analyses between age and the HCY-ED relationship showed that as age increases, the impact of HCY on ED strengthens. Based on this, subgroup analysis by age was carried out, revealing that in people aged 50 and above, HCY levels were significantly positively correlated with ED, especially when HCY levels exceeded 9.22 μmol/L, significantly increasing the risk of ED. Sensitivity analysis further confirmed the robustness of these findings. This study indicates that controlling HCY levels, especially in middle-aged and older men, might help prevent and treat ED, providing a foundation for future preventive strategies.

A couple presenting with more than 3 years' history of infertility and three miscarriages was tested for serum homocysteine levels and for the two principal MTHFR SNPs: 677C < T and 1298A < C, as per our general policy for patients with infertility of long duration. The woman was found to be wild type for both MTHFR SNPs with a serum homocysteine 10.5 µM, slightly higher than our accepted normal value of 8.

Objective: To analyze the prognostic value and threshold effect of serum C3, C4 in patients with multiple myeloma (MM).
Methods: The clinical data of 146 patients with MM who visited Suqian First People's Hospital from October 2016 to October 2019 were collected. The patients were divided into deceased group (42 cases) and survival group (104 cases) according to their prognosis and survival.

Observational studies have found that elevated serum homocysteine (Hcy) levels during pregnancy may be associated with the occurrence of neural tube defects (NTDs). However, the effect of Hcy on fetal neural development and its underlying molecular mechanisms remains unclear. To uncover the molecular mechanism, we analyzed the serum Hcy concentration in pregnant women with normal and abnormal pregnancy outcomes and treated zebrafish model embryos with high Hcy.

Background: α-synuclein, homocysteine (Hcy) and leucine-rich α2-glycoprotein (LRG) have been shown to correlate to Parkinson's disease (PD). However, it remains unclear whether these factors are associated with the occurrence of cognitive impairment (CI) in PD patients.
Methods: This study initially enrolled eligible PD patients without cognitive impairment.

Background: Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of peripheral vertigo, with frequent recurrence, particularly pronounced among middle-aged and elderly populations, significantly affecting patients' quality of life. This study aimed to identify predictive factors for recurrence in middle-aged and older patients with BPPV and to develop a nomogram prediction model based on these predictors.
Methods: This retrospective study included 582 participants aged ≥45 years who were selected from the electronic medical records system of the First Hospital of Changsha between March 2021 and March 2024.
