Meta-analysis of the association between dietary inflammation index and C-reactive protein level.

BACKGROUND: There have been various clinical studies on the effect of dietary inflammatory index (DII) on circulating inflammatory biomarkers, but the findings from these are contradictory. The aim of the present study was to clarify any association. METHODS: The PubMed, Embase, Web of Science and Cochrane Library database were searched for relevant studies from inception February 2021. There were no language restrictions. Two investigators independently selected eligible studies. Measures of association were pooled by using an inverse-variance weighted random-effects model. The heterogeneity among studies was examined using the I2 index. Publication bias, sensitivity and subgroup analyses were also performed. RESULTS: A total of 13 cross-sectional studies were identified, involving 54,813 participants. The adjusted pooled OR of C-reactive protein (CRP) levels for the highest (the most pro-inflammatory diet) versus lowest (the most anti-inflammatory diet) DII categories was 1.25 (95% CI: 1.18-1.32; I2  = 59.4%, P = .002). Subgroup analyses suggested the main source of study heterogeneity was the geographic area (Asia, Europe, or USA) and CRP levels (>3 mg/L or others). This finding was remarkably robust in the sensitivity analysis. CONCLUSION: The meta-analysis suggests that more pro-inflammatory DII scores were positively associated with CRP, the DII scores can be useful to assess the diet inflammatory properties and its association with low-grade inflammation.

Coping styles play intermediary roles between resilience and clinical communication ability among nursing students in traditional Chinese Medical university: A structural equation model analysis.

ABSTRACT: To prove the positive association between resilience and clinical communication ability among Chinese nursing students, and to determine whether coping styles play a mediating role in the relationship between them.Four hundred and seventy-one nursing students from a traditional Chinese Medical university were enrolled in this study. They completed some questionnaires, which included the Chinese Version of the Simplified Coping Style Questionnaire (SCSQ), Connor-Davidson Resilience Scale Chinese Version, and Clinical Communication Ability Scale. Structural equation modeling was utilized to analyses the relationships between coping styles, resilience, and clinical communication ability.Resilience was positively associated with clinical communication ability (P < .01). Coping styles which included positive coping and negative coping both significantly affected clinical communication ability (P < .01) and intermediated the relationship between resilience and clinical communication ability (P < .01).Resilience is positively related to clinical communication ability among Chinese nursing students, and coping styles intermediated the relationship between them, which may provide scientific evidence to aid in developing intervention strategies to improve interpersonal skills.

Meta-analysis of the association between dietary inflammatory index (DII) and upper aerodigestive tract cancer risk.

BACKGROUND: Epidemiological studies have reported an inconsistent relationship between dietary inflammatory index (DII) and upper aerodigestive tract (UADT) cancer risk. However, no systematic review or meta-analysis has been reported up to now. To quantify the association between DII and UADT cancer risk, we performed this meta-analysis. METHODS: The PubMed, EMBASE, Web of Science and Cochrane Library database were searched for relevant studies from inception December 2018. All case-control studies investigating the association between DII and UADT cancer risk were selected. RESULTS: A total of 9 case-control studies were identified, involving 13,714 participants. The adjusted pooled OR of UADT cancer for the highest (the most pro-inflammatory diet) vs lowest (the most anti-inflammatory diet) DII categories were 2.27 (95% CI: 1.89-2.73). Subgroup analysis showed that individuals with the highest category of DII score were independently associated with esophagus cancer (OR = 2.53, 95% CI: 1.74-3.68), oral cavity cancer (OR = 2.23, 95% CI: 1.73-2.86), pharyngeal cancer (OR = 2.02, 95% CI: 1.54-2.64), and laryngeal cancer (OR = 2.05, 95% CI: 0.85-4.93). CONCLUSION: This meta-analysis suggested that the most pro-inflammatory diets (the highest DII scores) are associated with increased UADT cancer risk. However, the association between DII and laryngeal cancer risk need to be further investigated.
