Objective: Postoperative delirium is common after extensive surgery. This study aimed to collate and synthesize published literature on risk factors for delirium in patients with head and neck cancer surgery. Methods: Three databases were searched (MEDLINE, Embase, and Cochrane Library) between January 1987 and July 2016. The Newcastle Ottawa Scale (NOS) was adopted to evaluate the study quality. Pooled odds ratios or mean differences for individual risk factors were estimated using the Mantel-Haenszel and inverse-variance methods. Results: They provided a total of 1940 patients (286 with delirium and 1654 without), and predominantly included patients undergoing head and neck cancer surgery. The incidence of postoperative delirium ranged from 11.50% to 36.11%. Ten statistically significant risk factors were identified in pooled analysis. Old age, age >70 years, male sex, duration of surgery, history of hypertension, blood transfusions, tracheotomy, American Society of Anesthesiologists physical status grade at least III, flap reconstruction and neck dissection were more likely to sustain delirium after head and neck cancer surgery. Conclusion: Delirium is common in patients undergoing major head neck cancer surgery. Several risk factors were consistently associated with postoperative delirium. These factors help to highlight patients at risk of developing delirium and are suitable for preventive action.

BackgroundDespite increasing evidence that has shown the association of ultra-processed foods (UPFs) with cancer risk, the results remain inconclusive. We, therefore, conducted the meta-analysis to clarify the association by including recently published studies.MethodsA comprehensive search was conducted in PubMed, Embase, and Web of Science to identify all relevant studies from inception to January 2023. To pool data, fixed-effects or random-effects models were used where appropriate. Subgroup analyses, sensitivity analyses, and publication bias tests were performed.ResultsA total of 13 studies (4 cohort studies and 9 case–control studies) were included in the analysis, with a total of 625,738 participants. The highest UPFs consumption was associated with increased risk of colorectal cancer (OR = 1.23, 95% CI: 1.10–1.38), colon cancer (OR = 1.25, 95% CI: 1.14–1.36), and breast cancer (OR = 1.10, 95% CI: 1.00–1.20) but not rectal cancer (OR = 1.18, 95% CI: 0.97–1.43) and prostate cancer (OR = 1.03, 95% CI: 0.93–1.12). In addition, the subgroup analyses showed that a positive association between UPFs consumption and colorectal cancer was observed among men (OR = 1.31, 95% CI: 1.15–1.50), whereas no significant association was observed among women (OR = 1.10, 95% CI: 0.94–1.29).ConclusionThe present meta-analysis suggests that high UPFs consumption is associated with a significantly increased risk of certain site-specific cancers, especially the digestive tract and some hormone-related cancers. However, further rigorously designed prospective and experimental studies are needed to better understand causal pathways.

Objective: We aimed to systematically evaluate the association between Dietary Inflammatory Index (DII) and mental health.Methods: We searched PubMed, Embase, and Web of Science from their inception to December 31, 2020. Categorical meta-analysis and dose–response meta-analysis were performed to evaluate the association between DII and mental health.Results: A total of 16 studies were included in this meta-analysis. Compared with the lowest DII category, the highest category was significantly associated with a variety of mental health outcomes, with the following pooled odds ratios (ORs) and 95% confidence intervals (95% CIs): 1.28 (1.17–1.39) for symptoms of depression, 1.27 (1.08–1.49) for symptoms of anxiety, 1.85 (1.43–2.40) for distress, and 4.27 (1.27–14.35) for schizophrenia. Furthermore, there was a linear dose–response relationship between DII and symptoms of depression in that a 1-unit increment in DII was associated with an increased risk of 6% for symptoms of depression (OR: 1.06, 95% CI: 1.03–1.19).Conclusion: The present study indicates that more pro-inflammatory diet, as estimated by the higher DII score, is associated with symptoms of mental disorder. It may be of clinical and public health significance regarding the development of novel nutritional psychiatry approaches to promote good mental health.

Papillary thyroid carcinoma (PTC) is the most prevalent cancer in the endocrine system, and the number of patients diagnosed with PTC has been increasing rapidly in recent years. Previous studies have reported that miR-145 plays an important role in many kinds of cancers, but its function in PTC remains unclear. In this study, we found that compared to paracancerous tissues, the level of miR-145 expression was significantly downregulated in PTC tissues.When miR-145 is overexpressed, migration and invasion of PTC cells were suppressed in vitro. In addition, we found that miR-145 downregulated the nuclear factor-κB (NF-κB) pathway in PTC cells. Taken together, our data suggest that miR-145 functions as a tumor suppressor in PTC with the suppressive effect related to downregulation of the NF-κB pathway.

BackgroundSarcopenia is a major public health problem. Depressive symptoms and dietary inflammatory potential play important roles in the development of sarcopenia. We aimed to disentangle the relationships between depressive symptoms, dietary inflammatory potential, and sarcopenia.MethodsA total of 6,082 participants from the National Health and Nutrition Examination Survey (NHANES) were included in the analyses. Sarcopenia was defined according to the Foundation for the National Institutes for Health (FNIH) criteria. The Depressive symptoms were assessed using the nine-item Patient Health Questionnaire (PHQ-9). Dietary Inflammatory Index (DII) was calculated based on 24-h dietary recall interview. Two sets of mediation models were constructed separately.ResultsDepressive symptoms and DII were associated with sarcopenia, with odds ratios [ORs] (95% CIs) 2.54 (1.27, 5.13) and 1.17 (1.00, 1.37), respectively. DII score mediated the association of depressive symptoms with low muscle mass, explaining a total of 10.53% of the association (indirect effect = 0.004). Depressive symptoms had a significant mediating effects on the association between DII with low muscle mass, explaining a total of 12.50% of the association (indirect effect = 0.001).ConclusionsOur findings suggested that both depressive symptoms and dietary inflammatory potential had direct effects, and indirect effects on low muscle mass, handgrip strength, muscle mass, through each other. It provides important insights into integrated nutritional and psychological intervention strategies in preventing sarcopenia.
