Association between dietary inflammatory potential and frailty is mediated by inflammation among patients with colorectal cancer: A cross-sectional study.

Patients with colorectal cancer (CRC) are at high risk of frailty, leading to reduced quality of life and survival. Diet is associated with frailty in the elderly through regulating inflammation. Thus, we hypothesized that dietary inflammatory potential (as assessed by dietary inflammatory index [DII]) might be associated with frailty in patients with CRC through regulating inflammatory biomarkers. A total of 231 patients with CRC were included in this cross-sectional study. Dietary intake was evaluated by 3-day, 24-hour dietary recalls, and frailty status was assessed in accordance with the Fried frailty criteria. Plasma inflammatory cytokines were determined in 126 blood samples. A total of 67 patients (29.0%) were frail, with significantly higher DII scores than nonfrail patients, accompanied with significantly increased interleukin-6 (IL-6) and decreased interleukin-10 (IL-10) concentrations. Each 1-point increase of DII was related to a 25.0% increased risk of frailty. IL-6 was positively correlated with frailty and DII, whereas IL-10 was negatively correlated. After adjusting for age, sex, body mass index, education level, smoking status, and energy, mediation analysis revealed that the association between DII and frailty was significantly mediated by IL-6 (average causal mediation effect [ACME], 0.052; 95% confidence interval, 0.020-0.087; P = .002) and IL-10 (ACME, 0.025; 95% confidence interval, 0.004-0.063; P = .016). The ρ values for the sensitivity measure at which estimated ACMEs were zero were 0.3 and -0.2 for IL-6 and IL-10, respectively. Therefore, a pro-inflammatory diet was associated with frailty in patients with CRC possibly in part by affecting circulating IL-6 and IL-10 concentrations.

The relationship between probiotics and retinopathy of prematurity in preterm infants: A population-based retrospective study in China.

Background: Retinopathy of prematurity (ROP) is a retinal vascular disease with a high incidence in premature infants and is a leading cause of childhood blindness worldwide. The purpose of our study was to analyze the association between the use of probiotics and retinopathy of prematurity. Methods: This study retrospectively collected clinical data of premature infants with gestational age <32 weeks and birth weight <1500 g admitted to the neonatal intensive care unit from January 1, 2019 to December 31, 2021 in Suzhou Municipal Hospital, China. Demographic and clinical data of the inclusion population were collected. The outcome was the occurrence of ROP. The chi-square test was used to compare categorical variables, while the t-test and the nonparametric Mann-Whitney U rank-sum test were used for continuous variables. Univariate and multivariate logistic regression were used to analyze the relationship between probiotics and ROP. Results: A total of 443 preterm infants met the inclusion criteria, of which 264 didn't receive probiotics and 179 were supplemented with probiotics. There were 121 newborns with ROP in the included population. The results of univariate analysis showed that the preterm infants with and without probiotics were significantly different in the gestational age, the birth weight, the one-minute Apgar score, the oxygen inhalation time, the acceptance rate of invasive mechanical ventilation, the prevalence of bronchopulmonary dysplasia, ROP and severe intraventricular hemorrhage and periventricular leukomalacia (P < 0.05). Unadjusted univariate logistic regression model result showed that probiotics (OR 0.383, 95% CI 0.240∼0.611) were the factors affecting ROP in preterm infants (P < 0.01). Multivariate logistic regression result (OR 0.575, 95% CI 0.333∼0.994) was consistent with univariate analysis (P < 0.05). Conclusion: This study showed that probiotic was associated with a reduced risk of ROP in preterm infants with gestational age of <32 weeks and birth weight of <1500 g, but more large-scale prospective studies are still needed.

Impacts of psychological resilience on self-efficacy and quality of life in patients with diabetic foot ulcers: a prospective cross-sectional study.

BACKGROUND: Patients with diabetic foot ulcer (DFU) usually have a poor quality of life (QoL) and self-efficacy, which is affected by many risk factors. However, the role of psychological resilience in QoL and self-efficacy in DFU patients has remained unclear. METHODS: This prospective cross-sectional study was performed in a single center from January 2018 to February 2020. A total of 98 DFU patients were enrolled in this study. Some demographic and clinical data were prospectively collected from participants. The psychological resilience of participants was assessed by Connor-Davidson resilience scale (CD-RISC). Self-efficacy was also assessed using the diabetes management self-efficacy scale (DMSES) and QoL was assessed by the 36-item short-form (SF-36) health survey. Univariable and multivariable linear regression were used to analyze the risk factors of self-efficacy and QoL. Then, logistic regression was used to analyze the predictors of psychological resilience among the participants. RESULTS: A CD-RISC score of more than 85 points was defined as high psychological resilience in this study; there were 28 participants diagnosed with high psychological resilience and 70 patients with low psychological resilience. Those with high psychological resilience had significantly higher self-efficacy, general health, vitality, social functioning, role emotional, and mental health than those with low psychological resilience. According to multivariable linear regression, low psychological resilience and older age were identified as risk factors of self-efficacy. On the contrary, low psychological resilience, older age, lower perceived social support and higher level of glycated hemoglobin were identified as risk factors of QoL. Finally, males had lower psychological resilience than females and those receiving more social support had higher psychological resilience than participants receiving less social support. CONCLUSIONS: Some risk factors of QoL and self-efficacy were identified in this study and these results may provide some evidence for the improvement of QoL and self-efficacy in DFU patients. Being female and receiving higher social support were shown to have potential for improving psychological resilience in DFU patients.

[Clinical efficacy of heated humidified high-flow nasal cannula in preventing extubation failure in neonates: a Meta analysis].

OBJECTIVE: To evaluate the efficacy and safety of heated humidified high-flow nasal cannula (HHHFNC) in preventing extubation failure in neonates. METHODS: A literature search was performed using PubMed, Cochrane Library, FMRS, and CNKI to collect the randomized controlled trials (RCTs) and quasi-RCTs which compared the clinical efficacy of HHHFNC and nasal continuous positive airway pressure (NCPAP) in preventing extubation failure in neonates. The identified studies were finally selected after full-text search and quality assessment and then subjected to a Meta analysis using RevMan 5.3. RESULTS: Five eligible trials involving 1040 neonates were included in the Meta analysis. The Meta analysis showed that there was no significant difference in treatment failure rate between the HHHFNC and the NCPAP groups. The HHHFNC group had significantly lower incidence rates of nasal trauma (OR=0.49, 95% CI: 0.34-0.71, P=0.0001) and pneumothorax (OR=0.27, 95% CI: 0.07-0.97, P=0.04) than the NCPAP group, but there were no significant differences in the duration to reach full oral feedings and the incidence rates of serious adverse events or other complications between the two groups, such as in-hospital mortality, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and retinopathy of prematurity. CONCLUSIONS: HHHFNC is safe and effective in preventing extubation failure in neonates.
