Evaluation and Comparison of Serum Vitamin D Levels between Injection Drug Users with and without Chronic Hepatitis C Infection in Hamadan-Iran.

Hepatitis C virus (HCV) infection causes disruption in the metabolism of biochemicals, such as vitamin D, and subsequently alters their serum level via the involvement of the liver. The current study aimed at determining the serum level of vitamin D in injection drug users with chronic HCV infection. The current case-control study was conducted on 46 injection drug users referred to Imam Khomeini Specialty Clinic in Hamadan City, Iran, between 2017 and 2019, when their HCV infection was diagnosed with HCV PCR test, and 46 healthy injection drug users as the control group in order to compare serum vitamin D levels and liver enzymes.

Association of calorie and carbohydrate intake with tumour grade in early diagnosis of breast cancer: a case-control study.

Background: This study aimed to investigate the association of calorie and carbohydrate intake with tumour grade in early detection of breast cancer (BC) in Iranian women.

Materials And Methods: This case-control study carried out on 62 women with high grade BC and 93 women with low grade BC. Information about confounding variables was collected through a questionnaire.

The association of quantitative insulin sensitivity indices (HOMA-IR and QUICKI) with anthropometric and cardiometabolic indicators in adolescents.

Introduction: Homoeostasis model assessment (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) are used to evaluate insulin resistance. The aim of this study was to investigate the association between quantitative insulin sensitivity indices and anthropometric and cardiometabolic indicators in adolescents.

Material And Methods: This descriptive-analytic cross-sectional study was conducted on 80 adolescents aged 12 to 13 years in Isfahan, Iran.

The Vitamins Involved in One-Carbon Metabolisms are Associated with Reduced Risk of Breast Cancer in Overall and Subtypes.

Some micronutrients like folate, vitamin B12, B6, and B2 are the source of coenzymes, which participate in one-carbon metabolism. Any disruption in this metabolism can interfere with DNA replication, repair and regulation of gene expression and ultimately promote the likelihood of carcinogenesis. This study aimed at investigating the relationship between the intakes of micronutrients involved in one-carbon metabolism with breast cancer (BrCa) and its subtype's odds.

Association between Dietary Inflammatory Index (DII) and Risk of Breast Cancer: a Case-Control Study.

Background: Breast cancer (BrCa) is the most common cancer among women worldwide and is the second leading cause of cancer-related death in women, in developed countries. This cancer is among the top five most common cancers in Iran. Studies have shown that dietary components are implicated in the etiology of BrCa.

The association between the Index of Nutritional Quality (INQ) and breast cancer and the evaluation of nutrient intake of breast cancer patients: A case-control study.

Objective: Breast cancer (BrCa) is the most frequently diagnosed cancer among females and second cancer after lung cancer in many societies. In Iran, the risk for BrCa is 1 in 35 and each year, 8000 new patients have been diagnosed with BrCa. Studies have shown that dietary components are implicated in the etiology of BrCa.
