The association between dietary intakes of zinc, vitamin C and COVID-19 severity and related symptoms: A cross-sectional study.

Background: The Coronavirus disease 2019 (COVID-19) pandemic has had a devastating impact on health systems, food supplies, and population health. This is the first study to examine the association between zinc and vitamin C intakes and the risk of disease severity and symptoms among COVID-19 patients.

Methods: This cross-sectional study included 250 recovered COVID-19 patients aged 18-65 years from June to September 2021.

Egg Consumption and Risk of All-Cause and Cause-Specific Mortality: A Systematic Review and Dose-Response Meta-analysis of Prospective Studies.

The association between egg consumption and mortality is extremely debatable. This study aimed to investigate the potential dose-response association of egg consumption with risk of mortality from all causes and cause-specific in the general population. The primary comprehensive literature search was conducted in PubMed/Medline, Scopus, ISI Web of Science, and Embase up to March 2021, as well as reference lists of relevant original papers and key journals.

Adherence to plant-based dietary patterns in relation to glioma: a case-control study.

Available evidence suggests a favorable association between adherence to a plant-based diet and disease prevention, but data on the link between such dietary intakes and cancer are scarce. We examined the association between the overall plant-based diet (PDI), healthy plant-based diet (hPDI), and unhealthy plant-based diet (uPDI) and risk of glioma. This case-control study was conducted on 128 newly diagnosed glioma patients, and 256 hospital-based controls.

Dietary glycaemic index and glycaemic load in relation to risk of breast cancer.

Objective: Previous studies on the association between glycaemic index (GI) and glycaemic load (GL) in relation to breast cancer risk are contradictory. The aim of this study was to examine the association between dietary GI and GL and risk of breast cancer in Iranian women.

Design: Population-based case-control study.

Dietary phytochemical index in relation to risk of stroke: a case-control study.

Background & Aim: No study explores the association of dietary phytochemical index (DPI) with stroke. This study was undertaken to obtain the required insight in this regard in Iranian adults.

Methods: This hospital-based case-control study was carried out on 195 stroke patients (diagnosed based on clinical and brained CT findings) and 195 control subjects with no history of cerebrovascular diseases or neurologic disorders).

Dietary phytochemical index in relation to risk of glioma: a case-control study in Iranian adults.

Background & Aim: No study is available that explores the association of dietary phytochemical index (DPI) with glioma. The objective of the current study was to assess this association in Iranian adults.

Methods: This hospital-based case-control study included 128 newly-diagnosed cases of glioma and 256 age- and sex-matched controls.

Does saffron supplementation have favorable effects on liver function indicators? A systematic review and meta-analysis of randomized controlled trials.

Several pharmaceutical and non-pharmaceutical approaches have been suggested to improve liver health. There is a large discrepancy in the effects of saffron supplementation on liver function in adults. To fill this knowledge gap, this systematic review and meta-analysis of randomized controlled trials (RCTs) assess the effects of saffron supplementation on liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP).

The association between plant-based dietary patterns and risk of breast cancer: a case-control study.

Limited data are available, linking the plant-based diets to breast cancer (BC). We examined the association of overall plant-based diet index (PDI), hypothesized healthful (hPDI) and unhealthful versions of a plant-based diet index (uPDI) with BC in Iranian women. This population-based case-control study included 350 cases with newly diagnosed BC and 700 age-matched apparently healthy controls.

Effects of saffron (Crocus sativus L.) supplementation on inflammatory biomarkers: A systematic review and meta-analysis.

The effect of saffron supplementation on subclinical inflammation remains inconclusive. We performed a systematic review and meta-analysis to summarize available findings on the effect of saffron supplementation on inflammatory biomarkers (C-reactive protein [CRP], tumor necrosis factor-α [TNF-α], and interleukin-6 [IL-6]) in adults. We searched PubMed/Medline, Scopus, Web of Science, and Google Scholar databases up to November 2019 using relevant keywords to identify eligible trials.

Adherence to the Mediterranean dietary pattern in relation to glioma: A case-control study.

Background: Although Mediterranean diet (MD) was associated with a lower risk of mortality and cancer, no data are available investigating the association between adherence to the MD and risk of glioma.

Methods: In this case-control study, we enrolled a total of 128 newly diagnosed patients with glioma, confirmed by pathological assessment, and 256 hospital-based controls from 2009 to 2011 in Tehran, Iran. A valid and reliable Block-format food frequency questionnaire (FFQ) was used to assess dietary intakes.

Refined grains consumption is associated with a greater odds of glioma.

: Grain consumption has been associated with brain carcinogenesis in earlier studies, however, no data are available examining the association between refined grains consumption and risk of glioma. The current study was done to investigate the association between refined grains consumption and risk of glioma in Iranian adults.: This hospital-based case-control study was performed on 128 pathologically confirmed cases with glioma and 256 age- and sex-matched controls in Tehran, Iran.
