Purpose: This study was conducted to evaluate the effect of alcohol consumption on breast cancer, adjusting for alcohol consumption misclassification bias and confounders.
Methods: This was a case-control study of 932 women with breast cancer and 1000 healthy control. Using probabilistic bias analysis method, the association between alcohol consumption and breast cancer was adjusted for the misclassification bias of alcohol consumption as well as a minimally sufficient set of adjustment of confounders derived from a causal directed acyclic graph. Population attributable fraction was estimated using the Miettinen's Formula.
Results: Based on the conventional logistic regression model, the odds ratio estimate between alcohol consumption and breast cancer was 1.05 (95% CI: 0.57, 1.91). However, the adjusted estimates of odds ratio based on the probabilistic bias analysis ranged from 1.82 to 2.29 for non-differential and from 1.93 to 5.67 for differential misclassification. Population attributable fraction ranged from 1.51 to 2.57% using non-differential bias analysis and 1.54-3.56% based on differential bias analysis.
Conclusion: A marked measurement error was in self-reported alcohol consumption so after correcting misclassification bias, no evidence against independence between alcohol consumption and breast cancer changed to a substantial positive association.

Background: Menstruation is a physiological process that may be accompanied by pain, headache, edema, emotional changes, and other symptoms, all of which affect quality of life. Although the results of some studies indicate lifestyle habits can affect the menstrual cycle and associated symptoms, few have investigated this issue, and even fewer have explored the impact of these symptoms on quality of life, in Spanish women.
Purpose: The objectives of this study were to determine the prevalence of dysmenorrhea and premenstrual syndrome (PMS) among students at a Spanish university, assess the impact of these conditions on quality of life, and analyze the relationship among lifestyle habits, dysmenorrhea, and PMS.

Objective: To examine the association between serum thyroid-stimulating hormone (TSH) levels with handgrip strength (HGS) and dynapenia in euthyroid postmenopausal women.
Methods: This was an exploratory cross-sectional study among 385 participants from the Department of Obstetrics, Gynecology, and Reproduction of the Dexeus Women's University Hospital, Barcelona, Spain. Age, age at menopause, adiposity, alcohol consumption, body mass index (BMI), and smoking status were recorded.

Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.

Nitrous oxide (NO) abuse is becoming increasingly popular worldwide. Moreover, the use of NO combined with other substances, such as alcohol, is also common. Accidental deaths associated with NO abuse are rare in forensic practice, with most fatal cases involving continuous inhalation equipment or exposure in a confined space.
