“…DII has been reported to have association with numerous plasma inflammatory markers (CRP and IL6) and multiple health outcomes (stoke, depression, CVDs, metabolic risk markers, cancer and all-cause and specific-cause mortality) [53]. Recent studies found that DII is negatively associated with the Mediterranean dietary pattern and is positively correlated with the PLR, NLR and SII among polycystic ovary syndrome patients [31]. Our study validated the positive role of DII on SIRI.…”

“…Next, a z-score was created by subtracting the global standard mean from the individual's estimated intake and dividing by its standard deviation [27]. Furthermore, this value was converted into a centered proportion score, with values ranging from 0 to 1, in order to minimize the effect of right skewing [31]. The proportion was then centered by doubling the proportion and subtracting 1 [12].…”

Inflammation is known as an important mechanism of cognitive dysfunction. Systemic immune inflammation index (SII) and system inflammation response index (SIRI) are two blood inflammatory markers, which are related to many chronic diseases including cognitive impairment. It is recognized that dietary inflammatory index (DII), which is used to estimate the overall inflammatory potential of diet, may be related to mild cognitive impairment (MCI) as well. This study aimed to explore the relationship between SII, SIRI and DII, as well as the role of these inflammatory indexes on MCI in elderly people. A total of 1050 participants from Beijing were included. Neuropsychological tests were used for cognitive evaluation. Energy-adjusted DII scores were calculated based on semi-quantitative food frequency questionnaire. Blood samples were tested for calculating SII and SIRI. Log-binomial regression models were used to estimate the correlation of indexes. After adjusting demographic characteristics, SII and SIRI in MCI individuals were higher than controls (p ≤ 0.001). DII, SII and SIRI had positive relationship with MoCA scores (p < 0.005). DII also correlated with SIRI in MCI (β = 0.11, p = 0.031). Higher DII and SIRI could definitely increase the risk of MCI, as well as DII and SII (p < 0.005). In conclusion, DII was positively correlated with blood inflammation. The elderly with higher level of DII and SIRI, or DII and SII could be considered as people with higher risk of developing MCI.

“…SII/SIRS is defined as NLR×platelets and is another effective indicator of inflammatory status that has been widely used to predict disease prognosis in recent studies 20 . In a case-control study with 527 participants, it was found that patients with PCOS had higher NLR, PLR, and SII ratios than those in the control group, which indicated that PCOS patients were in an inflammatory state 18 . In this study, there was no difference in SII values between groups, which was due to the small number of patients in the study.…”

“…The greater the platelet volume, the easier the release of inflammatory factors. Based on this information, some studies have found that PLR and MPV can be used as markers to detect inflammation 18 . In a study of 48 PCOS patients, Kebapcilar et al reported that WBC and MPV values were higher in the PCOS group than those in the group without PCOS 19 .…”

OBJECTIVE: In this study, the hormone profile, lipid profile, and inflammatory parameters of patients with polycystic ovary syndrome were compared with those of non-polycystic ovary syndrome patients to determine predictive markers in young polycystic ovary syndrome patients who have not yet had children. METHODS: Patients' age, height, weight, body mass index, waist circumference, degree of hirsutism, and ultrasound findings were recorded. Hormone profile, lipid levels, ratio of complete blood count parameters, monocyte/high-density lipoprotein ratio, and total cholesterol/high-density lipoprotein ratio were compared between groups. RESULTS: No statistically significant differences were found between groups in terms of age, weight, waist circumference, body mass index, and dysmenorrhea (p>0.05). A significant relationship was found between the height and the degree of hirsutism in the groups (p<0.05). It was found that prolactin, total testosterone, and dehydroepiandrosterone sulfate levels were statistically significantly higher in the polycystic ovary syndrome group compared to the control group. The polycystic ovary syndrome group had hemoglobin, leukocytes, lymphocytes, neutrophils, platelets, and statistically higher ratios of total cholesterol/high-density lipoprotein, Low-density lipoprotein/high-density lipoprotein, and triglycerides/highdensity lipoprotein. No statistically significant relationships were found between homeostatic model assessment insulin resistance, neutrophilto-lymphocyte ratio, and monocyte-to-high-density lipoprotein ratio between the groups (p<0.05). There was no significant difference in systemic immune inflammation index values between the groups. CONCLUSION: Polycystic ovary syndrome patients are at risk for short-and long-term complications, and the use of the total cholesterol/high-density lipoprotein, Low-density lipoprotein/high-density lipoprotein, and triglycerides/high-density lipoprotein ratios in clinical practice during the follow-up of these patients may allow easy follow-up for patients. The health status of polycystic ovary syndrome patients can be objectively determined by tracking these outcomes at regular intervals.

“…The many ways in which nutrients and dietary components shape the immune-inflammatory process are becoming increasingly evident. In recent years, a burgeoning body of research has illuminated the profound impact of dietary components on immune responses and the subsequent modulation of inflammatory markers, as encapsulated by the systemic immune-inflammation index (SII) [ 6 , 7 , 8 ]. Existing investigations have demonstrated that foods rich in live microorganisms, specifically those containing high levels of live microbes (LMC), such as fermented foods, offer a myriad of health advantages, including anti-inflammatory, antioxidative, anti-microbial, anti-diabetic, and anti-atherosclerotic activities [ 9 ].…”

The main topic of this research is the relationship between dietary intake of live microbe-containing (LMC) foods, recreational physical activity (RPA), and the systemic immune-inflammation index (SII). This study presented a cohort of 26,254 individuals in the National Health and Nutrition Examination Survey (NHANES), representing an estimated weighted population of 193,637,615 in the United States. Weighted multivariable linear regression models were used in consideration of the multi-stage sampling design. Results: The study found that medium-LMC foods were negatively associated with the SII [β (95% CI): −4.807 (−7.752, −1.862), p = 0.002], indicating that their intake was correlated with lower levels of the SII. However, no significant associations were found with low- or high-LMC foods. The study also explored the relationship between RPA and the SII, finding that more time spent in RPA was negatively associated with the SII [β (95% CI): −0.022 (−0.034, −0.011), p < 0.001]. A mediation analysis was conducted to investigate the role of RPA in the relationship between medium-LMC food intake and the SII. The analysis revealed that RPA had a notable indirect effect, contributing to 6.7% of the overall change in the SII. Overall, this study suggests that medium-LMC food intake and RPA may have beneficial effects on systemic immune inflammation.
