Introduction: Hypertension (HTN) is a common risk factor for various medical diseases. Recently, there is growing evidence focusing on the potential inflammatory properties of food in the developing HTN risk. However, limited data are indicating the link between the dietary inflammatory index score (DII) and HTN risk. Aim: This study aimed to investigate the relationship between DII score and HTN risk in middle-aged people. Methods: This case-control study was performed on 945 middle-aged participants (376 subjects with HTN and 569 control group). Usual dietary intakes were collected using a validated semi-quantitative food frequency questionnaire. The dietary inflammatory index (DII) for each participant was calculated with a standardized procedure, and the relationship between the risk of HTN and the DII score was investigated. Results: The multi-adjusted regression analysis showed that subjects with the higher DII score had a 1.61 times greater chance of developing HTN than individuals in the lowest ones (95% CI 1.07–2.65). Interestingly, after conducting a sex-based analysis, there was no significant relationship between DII score and risk of HTN in middle-aged women (95% CI 0.38–1.61). However, middle-aged men in the highest quartile of DII had greater (2.91 times) odds of HTN compared to the lowest quarter of DII (95% CI 1.52–5.23). Conclusion: The findings of this study suggested that adherence to a diet with a high inflammatory index could increase the risk of HTN in middle-aged men by approximately 2.9 times. However, following a diet with a high DII score had no significant relationship with HTN risk in middle-aged women. [ABSTRACT FROM AUTHOR]

The cumulative rate of death of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has necessitated better recognizing the risk factors of the disease and the COVID-19-induced mortality. This cross-sectional study aimed to determine the potential risk factors that predict COVID-19-related mortality concentrating on the initial recorded laboratory tests. We extracted admission's medical records of a total of 136 deaths related to COVID-19 and 272 discharged adult inpatients (≥18 years old) related to four referral centers from February 24th to April 12th, 2020, in Isfahan, Iran, to figure out the relationship between the laboratory findings and mortality beyond demographic and clinical findings. We applied the independent sample t test and a chichi square test with SPSS software to compare the differences between the survivor and non-survivor patients. A P value of less than 0.05 was considered significant. Our results showed that greater length of hospitalization (P≤0.001), pre-existing chronic obstructive pulmonary disease (P≤0.001), high pulse rate, hypoxia (P≤0.001), and high computed tomography scan score (P<0.001), in addition to high values of some laboratory parameters, increase the risk of mortality. Moreover, high neutrophil/lymphocyte ratio (OR, 1.890; 95% CI, 1.074-3.325, P=0.027), increased creatinine levels (OR, 15.488; 95% CI, 0.801-299.479, P=0.07), and elevated potassium levels (OR, 13.400; 95% CI, 1.084-165.618, P=0.043) independently predicted in-hospital death related to COVID-19 infection. These results emphasized the potential role of impaired laboratory parameters for the prognosis of fatal outcomes in adult inpatients. [ABSTRACT FROM AUTHOR]
