ObjectiveTo summarize the influence of dietary factors on the risk of pancreatic cancer and its possible mechanism. MethodThe literatures relevant to studies of the influence of dietary factors on the risk of pancreatic cancer were collected and reviewed. ResultsThe total intakes of carbohydrate, fatty acid, protein, and vitamin affected the risk of pancreatic cancer, and the different substances belonging to the same nutrients had different effects on the risk of pancreatic cancer. In addition to nutrients, the popular beverages and different dietary patterns in recent years also affected the risk of pancreatic cancer through certain mechanisms. ConclusionDietary factors can affect risk of pancreatic cancer through a variety of mechanisms, and it might decrease risk of pancreatic cancer by intervening in dietary factors in daily life for healthy people.
Objective To systematically review the efficacy of eight time-restricted eating strategies on overweight/obese adults using network meta-analysis. MethodsThe Scopus, MEDLINE, Embase, PubMed, Web of Science, and Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on the intervention effects of eight time-restricted eating strategies on overweight/obese adults from inception to September 18, 2024. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was performed using ADDIS 1.16.8 and Stata 18.0 software. ResultsA total of 23 RCTs involving 1 306 overweight/obese adults were included. The network meta-analysis revealed that compared with standard diets, the 8-hour time-restricted eating combined with a low-carbohydrate diet (MD=−4.01, 95%CI −5.95 to −2.08, P<0.05) showed better weight reduction effects. Compared with standard diets, the 8-hour time-restricted eating combined with a low-carbohydrate diet (MD=−3.54, 95%CI −5.44 to −1.63, P<0.05) and the 8-hour time-restricted eating combined with a low-sugar diet (MD=−4.19, 95%CI −8.33 to −0.05, P<0.05) significantly improved overall fat mass. Compared with standard diets, the 8-hour time-restricted eating combined with a low-sugar diet (MD=−15.42, 95%CI −29.12 to −1.72, P<0.05) had a better effect on fasting blood glucose control. The 8-hour time-restricted eating combined with high-intensity interval training (MD=−3.68, 95%CI −6.57 to −0.79, P<0.05) showed better results in reducing waist circumference. No statistical significance was found in direct comparisons regarding bone mineral content. The efficacy ranking showed that the 8-hour time-restricted eating combined with a low-carbohydrate diet was most effective for weight reduction; the 8-hour time-restricted eating combined with a low-sugar diet was more effective in reducing overall fat mass and controlling fasting blood glucose; the 8-hour time-restricted eating combined with calorie restriction had significant effects on waist circumference improvement; and the 8-hour time-restricted eating combined with high-intensity interval training was more effective for increasing bone mineral content. ConclusionBased on the results of the network meta-analysis and ranking, different time-restricted eating strategies have specific advantages for the intervention of overweight or obese individuals. The choice of the appropriate strategy should consider individual dietary habits and health conditions. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective Anorexia nervosa is a disorder of high morbidity and significant mortality. The aim of the present review was to evaluate the evidence from randomized controlled trials for the efficacy of outpatient psychotherapies used in the treatment of older adolescents ( aged ＞16 years) and adults with anorexia nervosa. Methods The search strat egy comprised database searches of Medline, EXTRAMED, EMBASE, PSYCLIT, Current Contents, Cochrane Con trolled Trials Register and the Depression and Anxiety Neurosis Cochrane Group ( CCDAN), the search date was Novem ber 2002. A hand-search of The International Journal of Eating Disorders from its first issue up to March 2003, and the ref erence lists of all papers selected. Personal letters were sent to identified leading researchers published in the area, requesting information on trials that are unpublished. All randomized controlled trials of adult individual outpatient therapy for anorexia nervosa, as defined by the DSM-IV or similar international criterion, were included. Quality ratings were made according to the CCDAN criteria. A range of outcome variables were selected, including physical state, severity of eating disorder attitudes and behefs, interpersonal function, and general psychiatric symptom severity. Continuous outcome data comparisons were planned with the standardized mean difference statistic, and binary outcome comparisons planned with the relative risk statistic. Results Six small trials only, two of which included children or adolescents, were identified from the search and aggregation of data was not possible. Bias was possible due to lack of blinding of outcome assessments. The results in two trials suggested that "treatment as usual" or similar may be less efficacious than a specific psychotherapy. No specific treatment was consistently superior to any other specific approach. Dietary advice as a control arm had a 100% non-completion rate in one trial. Conclusions No specific approach can be recommended from this review. It is unclear why "treatment as usual" performed so poorly, or why dietary advice alone appeared so unacceptable. There is an urgent need for large well-designed trials in this area.
ObjectiveTo investigate the effect of sleeve gastrectomy on preventing adipose infiltration and LOX-1 expression in aortic epithelium of high-fat-diet-induced obese rats. MethodsTwenty-four Wistar rats were randomized into normal chow group (CO group), high-fat diet group (HD group), and high-fat diet combined with sleeve gastrectomy group (SG group). Rats of three groups before operation and CO group after operation were fed with normal diet, rats of HD and SG group were fed with high-fat diet. Body weight of all the rats were examined on day 10, 20, and 30 after operation, respectively. Animals were sacrificed on day 30 after operation and plasma HDL and LDL were detected by ELISA, LOX-1 and LOX-1 mRNA expression in aortic epithelium were measured by Western blot and real-time RT-PCR, respectively. Immunochemical histological Nile red stain was adopted in adipose infiltration examination of aorta. ResultsThe body weights in HD group were much higher than those of other groups （Plt;0.01）. The HDL in CO, HD, and SG groups was (32.9±6.2) mg/dl, (43.4± 4.0) mg/dl, and (37.5± 4.3) mg/dl, respectively. The LDL in CO, HD, and SG groups was (31.8±4.5) mg/dl, (53.3±5.1) mg/dl, and (40.5±3.7 ) mg/dl, respectively. The HDL and LDL values in HD group were higher than those of other two groups (Plt;0.05, Plt;0.01). The LOX-1 protein and mRNA expressions in HD group were much higher than those of other groups (Plt;0.01). Adipose staining in HD group was also ber than that of other groups. ConclusionsHigh-fat diet can induce elevation of LOX-1 protein and mRNA expression in aorta. Sleeve gastrecto my can relieve plasma LDL level, as a result, LOX-1 protein and mRNA expression should be down-regulated.
Objective To understand the current situation of dietary organophosphate esters (OPEs) exposure, its effect on human health and its role in the occurrence and development of digestive system disease. Method We searched, analyzed and summarized the relevant literatures on the exposure of OPEs in diet and its effects on digestive system health. Results OPEs had long-term, extensive, and continuous exposure in diet. Although the exposure levels of different OPEs were different in time and space, its impact on digestive system health could not be ignored. OPEs might play a potential role in digestive system injury and tumorigenesis through the activation of inflammation related pathways and the expression change of cancer-related gene. Conclusions OPEs exposure may be a potential risk factor for digestive system injury and tumor. Further exploration of its pathogenic mechanism is of great significance to the screening of high risk factors, disease prevention, and health care.

Cardiovascular disease is the leading cause of death in the world. The influence of diet on atherosclerotic cardiovascular disease (ASCVD) should not be underestimated. In 2022, the American College for Preventive Cardiology (ASPC) issued guidelines, which emphasized the importance of changing dietary patterns for the prevention of ASCVD and its risk factors, recommended the best diet for ASCVD prevention, and discussed dietary recommendations for ASCVD prevention in special populations. This paper interprets this guideline, aiming to provide help for clinical practice.
